Intensive follow-up of patients after curative surgery for colorectal cancer is common in clinical practice, but evidence of a survival benefit is limited. To examine overall mortality, colorectal cancer-specific mortality, and colorectal cancer-specific recurrence rates among patients with stage II or III colorectal cancer who were randomized after curative surgery to 2 alternative schedules for follow-up testing with computed tomography and carcinoembryonic antigen. Unblinded randomized trial including 2509 patients with stage II or III colorectal cancer treated at 24 centers in Sweden, Denmark, and Uruguay from January 2006 through December 2010 and followed up for 5 years; follow-up ended on December 31, 2015. Patients were randomized either to follow-up testing with computed tomography of the thorax and abdomen and serum carcinoembryonic antigen at 6, 12, 18, 24, and 36 months after surgery (high-frequency group; n = 1253 patients) or at 12 and 36 months after surgery (low-frequency group; n = 1256 patients). The primary outcomes were 5-year overall mortality and colorectal cancer-specific mortality rates. The secondary outcome was the colorectal cancer-specific recurrence rate. Both intention-to-treat and per-protocol analyses were performed. Among 2555 patients who were randomized, 2509 were included in the intention-to-treat analysis (mean age, 63.5 years; 1128 women [45%]) and 2365 (94.3%) completed the trial. The 5-year overall patient mortality rate in the high-frequency group was 13.0% (161/1253) compared with 14.1% (174/1256) in the low-frequency group (risk difference, 1.1% [95% CI, -1.6% to 3.8%]; P = .43). The 5-year colorectal cancer-specific mortality rate in the high-frequency group was 10.6% (128/1248) compared with 11.4% (137/1250) in the low-frequency group (risk difference, 0.8% [95% CI, -1.7% to 3.3%]; P = .52). The colorectal cancer-specific recurrence rate was 21.6% (265/1248) in the high-frequency group compared with 19.4% (238/1250) in the low-frequency group (risk difference, 2.2% [95% CI, -1.0% to 5.4%]; P = .15). Among patients with stage II or III colorectal cancer, follow-up testing with computed tomography and carcinoembryonic antigen more frequently compared with less frequently did not result in a significant rate reduction in 5-year overall mortality or colorectal cancer-specific mortality. clinicaltrials.gov Identifier: NCT00225641.

To compare the patient-reported, clinical, and radiographic outcome of 2 methods of internal fixation in distal radius fractures. Fifty patients, mean age 56 years (range, 21-69 years) with primarily nonreducible or secondarily redisplaced distal radius fractures were randomized to open reduction internal fixation using volar locking plates (n = 25) or fragment-specific fixation (n = 25). The patients were assessed on grip strength, range of motion, patient-reported outcome (Quick Disabilities of the Arm, Shoulder, and Hand), pain (visual analog scale), health-related quality of life (Short Form-12 [SF-12]), and radiographic evaluation. Grip strength at 12 months was the primary outcome measure. At 12 months, no difference was found in grip strength, which was 90% of the uninjured side in the volar plate group and 87% in the fragment-specific fixation group. No differences were found in range of motion and the median Quick Disabilities of the Arm, Shoulder, and Hand score was 5 in both groups. The overall complication rate was significant, 21% in the volar locking plate group, compared with 52% in the fragment-specific group. In treatment of primarily nonreducible or secondarily redisplaced distal radius fractures, volar locking plates and fragment-specific fixation both achieve good and similar patient-reported outcomes, although more complications were recorded in the fragment-specific group.

To evaluate the diagnostic value and potential therapeutic impact of Peking Union Medical College Hospital critical ultrasonic management (PCUM) in the early management of critically ill patients with acute respiratory failure (ARF). Patients admitted into the ICU of Peking Union Medical College Hospital for ARF were consecutively recruited over a 18-month period. Patients were randomly divided into conventional group and PCUM group (critical care ultrasonic examination was added in addition to conventional examinations). The two groups were compared with respect to time to preliminary diagnosis, time to final diagnosis, diagnostic accuracy, time to treatment response, time to other examination. A total of 187 patients were included in this study. The two groups showed no significant differences in general clinical information or final diagnosis (P > 0.05). The PCUM group had a shorter time to preliminary diagnosis, time to final diagnosis, time to treatment response, time to X-ray/CT examination, and a higher diagnostic accuracy than the conventional group (P < 0.001). PCUM had high sensitivity and specificity for the diagnosis of acute respiratory distress syndrome (ARDS) (sensitivity 92.0%, specificity 98.5%), acute pulmonary edema (sensitivity 94.7%, specificity 96.1%), pulmonary consolidation (sensitivity 85.7%, specificity 98.6%), COPD/asthma (sensitivity 84.2%, specificity 98.7%). The PCUM is seem to be an attractive complementary diagnostic tool and able to contribute to an early therapeutic decision for the patients with ARF.

The aim of this study was to quantify the amount of brain damage suffered by patients who underwent off-pump coronary artery bypass grafting (OPCAB) in which S-100β protein and neuron-specific enolase were used. Thirty-four patients undergoing scheduled OPCAB were enrolled in the study. The patients were divided into two groups according to the results of their magnetic resonance angiography (MRA) and cervical ultrasonography: 13 patients had cervical or intracranial arterial stenosis (Group A), and 21 patients did not (Group B). Blood samples were collected from the arterial catheters immediately before surgery, upon arrival to the intensive care unit, and 6 and 24 hours after surgery. In blood samples collected from patients upon arrival to the intensive care unit, the maximum concentration of serum s-100β protein in Group A was significantly higher than that of Group B (p = 0.029). Though patients in Group A tended to have higher maximum neuron-specific enolase (NSE) concentrations, there were no significant differences in NSE concentrations at any point between the two groups. Our findings show a correlation between the stenosis detected by MRA or cervical ultrasonography and brain damage after OPCAB.

For desensitization of ABO-incompatible kidney transplant recipients we recently proposed nonantigen-specific immunoadsorption (IA) and rituximab. We now compared clinical outcomes of 34 ABO-incompatible living-donor kidney recipients who were transplanted using this protocol with that of 68 matched ABO-compatible patients. In addition, we analyzed efficacy and cost of nonantigen-specific as compared to blood group antigen-specific IA. Before desensitization, the median isoagglutinin titer of 34 ABO-incompatible patients was 1:64 (Coombs technique). Patients received a median of 7 preoperative IA treatments. Twenty-four patients had a median of 2 additional plasmapheresis treatments to reach the preoperative target isoagglutinin titer of 1:8 or less. After a median postoperative follow-up of 22 months, overall graft survival in the ABO-incompatible group was not significantly different from that in ABO-compatible patients (log-rank P = 0.20), whereas patient survival tended to be lower (log-rank P = 0.05). The incidence of rejection episodes was 15% in both groups. The ABO-incompatible kidney recipients had a higher incidence of BK virus replication (P = 0.04) and nephropathy (P = 0.01) and showed more often colonization with multidrug resistant bacteria (P = 0.02). In comparison to blood group antigen-specific IA, nonantigen-specific IA showed equal efficacy but was associated with reduction in cost. Clinical outcomes of ABO-incompatible patients desensitized with a nonantigen-specific IA device and rituximab do not differ from that of matched ABO-compatible patients although a trend toward reduced patient survival was noted. Special attention must be paid to the higher incidence of BK virus infection in recipients of ABO-incompatible grafts.

Specific efficacy expectations mediate exercise compliance in patients with COPD.

Social learning theory has generated two different approaches for the assessment of expectancies. Bandura argues that expectancies are specific and do not generalize. Therefore, he prefers measures of specific efficacy expectations. Others endorse the role of generalized expectancies measured by locus of control scales. The present study examines specific versus generalized expectancies as mediators of changes in exercise behavior among 60 older adult patients with Chronic Obstructive Pulmonary Disease. The patients were given a prescription to increase exercise and randomly assigned to experimental groups or control groups. All groups received attention but only experimental groups received training to increase their exercise. After 3 months, groups given specific training for compliance with walking significantly increased their activity in comparison to the control group receiving only attention. These changes were mediated by changes in perceived efficacy for walking, with efficacy expectations for other behaviors changing as a function of their similarity to walking. A generalized health locus of control expectancy measure was less clearly associated with behavior change. The results are interpreted as supporting Bandura's version of social theory.

[Purpose] The aim of this study was to compare the effects of "McGill stabilization exercises" and "conventional physiotherapy" on pain, functional disability and active back flexion and extension range of motion in patients with chronic non-specific low back pain. [Subjects and Methods] Thirty four patients with chronic non-specific low back pain were randomly assigned to McGill stabilization exercises group (n=17) and conventional physiotherapy group (n=17). In both groups, patients performed the corresponding exercises for six weeks. The visual analog scale (VAS), Quebec Low Back Pain Disability Scale Questionnaire and inclinometer were used to measure pain, functional disability, and active back flexion and extension range of motion, respectively. [Results] Statistically significant improvements were observed in pain, functional disability, and active back extension range of motion in McGill stabilization exercises group. However, active back flexion range of motion was the only clinical symptom that statistically increased in patients who performed conventional physiotherapy. There was no significant difference between the clinical characteristics while compared these two groups of patients. [Conclusion] The results of this study indicated that McGill stabilization exercises and conventional physiotherapy provided approximately similar improvement in pain, functional disability, and active back range of motion in patients with chronic non-specific low back pain. However, it appears that McGill stabilization exercises provide an additional benefit to patients with chronic non-specific low back, especially in pain and functional disability improvement.

Radical prostatectomy has recently been shown to prolong cancer-specific survival compared to watchful waiting in patients with localized prostate cancer. Most patients who seek medical advice for this disease are treated in hospitals in which the operation is performed relatively infrequently. The aim of this study is to report the oncological outcome at intermediate- to long-term follow-up after radical prostatectomy performed in a community hospital. A total of 148 patients underwent radical prostatectomy at Ryhov County Hospital between 1985 and 1997. Patients without T3 tumours, prostate-specific antigen (PSA) >10 ng/ml or poorly differentiated tumours were judged to be in a low-risk group, those with one risk factor to be in an intermediate group and those with two or more factors to be in a high-risk group. The projected biochemical disease free- and cancer-specific survival rates were compared between these risk groups. Median follow-up was 96 months for surviving patients. Patients in the low- and intermediate risk groups had equal 10-year PSA-free survival rates of 68.8%, while that in the high-risk group was only 19.3% (9-year data). Corresponding cancer-specific survival rates were 93% and 84%, respectively. The oncological outcome seems comparable to that reported in the literature, even when the operation is performed in a low-volume community-based setting.

Low Back Pain (LBP) results in significant level of disability, producing significant restriction on usual activity such as an inability to work. Nearly two third of the adults are affected by non-specific low back pain at some point in their lives. The purpose of the study was to determine the effect of core stabilization exercises in comparison with conventional exercises on pain, functional status in patients with non-specific LBP. Thirty patients diagnosed with non-specific LBP participated with age group between 20-50 years and divided in to 2 groups, one with core stabilization exercises and other conventional exercises, 15 subjects each. Three months study, pre and post treatment outcome measures used were VAS for pain intensity and Modified Oswestry Low Back Pain Disability Index for functional status (disability). Data were analyzed using student 't' test (paired and unpaired). Whereas both groups improved significantly from the initiation of treatment, a between-group comparison revealed significantly greater (p<0.001) improvements regarding pain and functional status for experimental group compared to control group. Core stabilization exercises were found to be more effective in reducing pain and improving functional status by decreasing disability of patients with non-specific low back pain in comparison with conventional exercises.

Invasive mucormycosis (IM) is an emerging life-threatening fungal infection. It is difficult to obtain a definite diagnosis and to initiate timely intervention. Mucorales-specific T cells occur during the course of IM and are involved in the clearance of the infection. We have evaluated the feasibility of detecting Mucorales-specific T cells in hematological patients at risk for IM, and have correlated the detection of such cells with the clinical conditions of the patients. By using an enzyme linked immunospot assay, the presence of Mucorales-specific T cells in peripheral blood (PB) samples has been investigated at three time points during high-dose chemotherapy for hematologic malignancies. Mucorales-specific T cells producing interferon-γ, interleukin-10 and interleukin-4 were analysed in order to detect a correlation between the immune response and the clinical picture. Twenty-one (10.3%) of 204 patients, accounting for 32 (5.3%) of 598 PB samples, tested positive for Mucorales-specific T cells. Two groups could be identified. Group 1, including 15 patients without signs or symptoms of invasive fungal diseases (IFD), showed a predominance of Mucorales-specific T cells producing interferon-gamma. Group 2 included 6 patients with a clinical picture consistent with invasive fungal disease (IFD): 2 cases of proven IM and 4 cases of possible IFD. The proven patients had significantly higher number of Mucorales-specific T cells producing interleukin-10 and interleukin-4 and higher rates of positive samples by using derived diagnostic cut-offs when compared with the 15 patients without IFD. Mucorales-specific T cells can be detected and monitored in patients with hematologic malignancies at risk for IM. Mucorales-specific T cells polarized to the production of T helper type 2 cytokines are associated with proven IM and may be evaluated as a surrogate diagnostic marker for IM.

An experience of a tentative contribution of the nurses to the health policy planning is described. Fifty one focus groups were organized, with nurses from different contexts (hospital, district, free lance nurses; caring for paediatric, geriatric surgical and medical patients) and nurses were asked to identify problems encountered in patients care, select one, discuss contributing causes assign a weight (from 1 to 100) and define the nurses' contribution to the resolution/improvement of each cause. The problems were discussed in groups and possible solutions identified, with specific attention to the potential implications of regional health policies. The main difficulties identified were the lack of continuity in patients care (for geriatric and paediatrics patients), 12 groups, and the management of chronic patients (7 groups); the lack of information to patients, 6 groups; the appropriateness of care, from hospital admissions to waiting lists, 5 groups; the management of surgical patients, 5 groups; the lack of nursing personnel, 5 groups; the safety of patients and health personnel, 4 groups; and other problems reported by less than 3 groups. This experience allowed nurses to reflect on health care problems throughout the trajectory from the specific problem to its general implications, also for the health care policies. The solutions identified in fact, encompass a dimension relevant for health policy planning. It is also an experience of opportunity (and feasibility) of involvement of the "general nurses" and not only nurse managers, to reflect on practice and propose a specific and original contribution to the development of regional and local policies.

In this study, we compared a cognition-specific computer-based cognitive training program with a motion-controlled computer sports game that is not cognition-specific for their ability to enhance cognitive performance in various cognitive domains in patients with Parkinson disease (PD). Patients with PD were trained with either a computer program designed to enhance cognition (CogniPlus, 19 patients) or a computer sports game with motion-capturing controllers (Nintendo Wii, 20 patients). The effect of training in 5 cognitive domains was measured by neuropsychological testing at baseline and after training. Group differences over all variables were assessed with multivariate analysis of variance, and group differences in single variables were assessed with 95% confidence intervals of mean difference. The groups were similar regarding age, sex, and educational level. Patients with PD who were trained with Wii for 4 weeks performed better in attention (95% confidence interval: -1.49 to -0.11) than patients trained with CogniPlus. In our study, patients with PD derived at least the same degree of cognitive benefit from non-cognition-specific training involving movement as from cognition-specific computerized training. For patients with PD, game consoles may be a less expensive and more entertaining alternative to computer programs specifically designed for cognitive training. This study provides Class III evidence that, in patients with PD, cognition-specific computer-based training is not superior to a motion-controlled computer game in improving cognitive performance.

This was a randomised, double-blind, placebo-controlled study to evaluate the efficacy and safety of Vitamin C vaginal tablets (250 mg) given once a day in patients suffering from non-specific vaginitis. The total length of the study was 20 days, including a treatment phase of 6 days. The primary end-point was the presence in the two groups of non-specific vaginitis 1 and 2 weeks after the end of treatment, as assessed by at least 3 out of the 4 characteristic symptoms: discharge, fishy odour, vaginal pH >/= 4.7, and presence of clue cells. Secondary end-points were the individual symptoms and signs, above reported, and pruritus, fever, superinfections, microscopic findings on vaginal smear, and colposcopy. One hundred female patients aged 18 years or older and suffering from non-specific vaginitis were included in the study after giving their informed consent. Fifty were randomised to the active treatment and 50 to placebo. Seven patients, three in the Vitamin C group and four in the placebo group, were lost to follow-up and did not complete the treatment period. Two patients in the active group showed protocol deviations (age under 18 years and HIV-positive, respectively). The two groups resulted comparable for demographics, history and baseline clinical picture. A cluster analysis of the four main symptoms showed a statistically significant difference between the active group and the placebo group; significantly more patients were still affected by non-specific vaginitis after placebo (35.7%) compared to patients treated with Vitamin C tablets (14.0%). The meaningful secondary variable, referring to the microscopic examination of vaginal smear, supported the trend for efficacy in the Vitamin C treated group. The clue cells disappeared in 79% of patients treated with the drug and in 53% of patients on placebo. Similarly, bacteria disappeared in 77 and 54%, respectively, while lactobacilli reappeared in 79.1 and 53.3%, respectively. Vaginal pH values decreased significantly in both groups, but the frequency rate of subjects with pH >/= 4.7, as measured 1 week after the drug discontinuation, was significantly lesser in the Vitamin C group (16.3%) than in the placebo group (38.6%). Adverse events occurred in four patients, two on placebo (pruritus, cystitis) and two on Vitamin C (two candidiasis).

Depression is associated with increased symptom burden in the setting of chronic medical conditions. Studies investigating the influence of depression on the symptoms of chronic rhinosinusitis (CRS) are lacking. The purpose of this project was to establish the prevalence of depression in patients with CRS and to explore the impact of this disorder on disease-specific symptoms and general quality of life (QOL) in the preoperative and postoperative setting. We reviewed the records of 320 consecutive patients presenting with sinonasal symptoms to our specialty sinus clinic. Patients with CRS were evaluated by nasal endoscopy, CT imaging, and validated questionnaires including the Chronic Sinusitis Survey and SF-8 Health Survey, a QOL measurement. Findings in CRS patients with depression were compared with a matched-control group of CRS patients without depression before and after endoscopic sinus surgery. Overall, 26% of patients presenting with sinonasal symptoms had a diagnosis of depression. After evaluation including CT imaging, 33% of the initial population was diagnosed with CRS. The prevalence of depression in these CRS patients was 25%. Disease-specific symptoms were similar between groups; however, depressed CRS patients reported significantly worse pain and energy level and difficulty with daily activities (p < 0.050) when compared with a control group of CRS patients without depression. Postoperatively, nondepressed patients showed a marked improvement in disease-specific as well as general QOL scores (p < 0.050), whereas depressed patients did not. CRS patients with and without depression have similarly poor disease-specific symptoms. However, depressed CRS patients have poorer disease-specific and overall QOL outcomes after sinus surgery.

AB0 blood groups and Rhesus factor expression have been associated with carcinogenesis, response to treatment and tumor progression in several malignancies. The aim of the present study was to test the hypothesis that AB0 blood groups and Rhesus factor expression are associated with clinical outcome in patients with epithelial ovarian cancer (EOC). AB0 blood groups and Rhesus factor expression were evaluated in a retrospective multicenter study including 518 patients with EOC. Their association with patients' survival was assessed using univariate and multivariable analyses. Neither AB0 blood groups nor Rhesus factor expression were associated with clinico-pathological parameters, recurrence-free, cancer-specific, or overall survival. In a subgroup of patients with high-grade serous adenocarcinoma, however, blood groups B and AB were associated with a better 5-year cancer-specific survival rate compared to blood groups A and 0 (60.3 ± 8.6% vs. 43.8 ± 3.6%, p = 0.04). Yet, this was not significant in multivariable analysis. AB0 blood groups and Rhesus factor expression are both neither associated with features of biologically aggressive disease nor clinical outcome in patients with EOC. Further investigation of the role of the blood group B antigen on cancer-specific survival in the subgroup of high-grade serous should be considered.

To compare the sensitivity and specificity of Moorfields regression analysis (MRA) and glaucoma probability score (GPS) between healthy and glaucomatous eyes with Heidelberg Retinal Tomograph 3 (HRT-3). The study included 120 eyes of 75 glaucoma patients and 138 eyes of 73 normal subjects, for a total of 258 eyes of 148 individuals. All measurements were performed with the HRT-3. Diagnostic test criteria (sensitivity, specificity, etc.) were used to evaluate how efficiently GPS and MRA algorithms in the HRT-3 discriminated between the glaucoma and control groups. The GPS showed 88 % sensitivity and 66 % specificity, whereas MRA had 71.5 % sensitivity and 82.5 % specificity. There was 71 % agreement between the final results of MRA and GPS in the glaucoma group. Excluding borderline patients from both analyses resulted in 91.6 % agreement. In the control group the level of agreement between MRA and GPS was 64 % including borderline patients and 84.1 % after excluding borderline patients. The accuracy rate is 92 % for MRA and 91 % for GPS in the glaucoma group excluding borderline patients. The difference was nor statistically different. In both cases, agreement was higher between MRA and GPS in the glaucoma group. We found that both sensitivity and specificity increased with disc size for MRA, while the sensitivity increased and specificity decreased with larger disc sizes for GPS. HRT is able to quantify and clearly reveal structural changes in the ONH and RNFL in glaucoma.

Is the simple mean of the costs per diabetes patient a suitable tool with which to compare care groups? Do the total costs of care per diabetes patient really give the best insight into care group performance? Cross-sectional, multi-level study. The 2009 insurance claims of 104,544 diabetes patients managed by care groups in the Netherlands were analysed. The data were obtained from Vektis care information centre. For each care group we determined the mean costs per patient of all the curative care and diabetes-specific hospital care using the simple mean method, then repeated it using the 'generalized linear mixed model'. We also calculated for which proportion the differences found could be attributed to the care groups themselves. The mean costs of the total curative care per patient were €3,092 - €6,546; there were no significant differences between care groups. The mixed model method resulted in less variation (€2,884 - €3,511), and there were a few significant differences. We found a similar result for diabetes-specific hospital care and the ranking position of the care groups proved to be dependent on the method used. The care group effect was limited, although it was greater in the diabetes-specific hospital costs than in the total costs of curative care (6.7% vs. 0.4%). The method used to benchmark care groups carries considerable weight. Simply stated, determining the mean costs of care (still often done) leads to an overestimation of the differences between care groups. The generalized linear mixed model is more accurate and yields better comparisons. However, the fact remains that 'total costs of care' is a faulty indicator since care groups have little impact on them. A more informative indicator is 'costs of diabetes-specific hospital care' as these costs are more influenced by care groups.

Various specific and non-specific dermatological manifestations can be found in patients with psychiatric ailments. Most studies in this regard have been conducted on an outpatient basis and not much work has been done on patients admitted with psychiatric diseases. This cross-sectional hospital-based study involved two groups of admitted psychiatric patients over a period of 1 year, involving 100 patients in each group. In the family ward group patients were admitted with accompanying family members, whereas in the closed ward group patients were kept under custodial care. In the family ward setting, eczema was the most common finding, observed in 29 patients, followed by atrophic scarring in 28 patients, erythema ab igne in 25 patients, and bacterial infections in five patients. Various forms of nail changes were seen in 18 patients. In the closed ward group, most common dermatological involvement was parasitic infestation, seen in 56 patients, followed by generalized pruritus in 53 patients and atrophic scarring in 52 patients. Thirty-eight patients had nail changes. Skin manifestations are more common in chronic neglected psychiatric patients under custodial care. The authors stress upon the importance of familial care provided to psychiatric patients living in custodial settings.

To assess the survival outcomes of oral cavity squamous cell carcinoma (OCSCC) by differing geographical location. Demographic, pathologic, treatment, and survival data was obtained from OCSCC patients from 1998-2010 in Alberta, Canada. 554 patients were included from 660 OCSCC patients. Overall, disease-specific, and disease-free survivals were estimated with Kaplan-Meier and Cox regression analyses. Patients were grouped by geographic locations. Patients from urban locations had improved overall, disease-specific, and disease-free survival compared to rural locations (p<0.05). Two and five year estimates of overall survival were significantly higher in the urban cohort at 84% and 78%, versus rural with 48% and 44%, respectively (p<0.05). Disease-specific and disease-free survival rates were also superior in the urban group (p<0.05). Diagnosis to treatment time for all 3 geographical groups was not found to be statistically significant (p>0.05). This study shows that patients with OCSCC living in urban settings have improved survival compared to rural groups. Copyright © 2015 Elsevier Ltd. All rights reserved.

High levels of rejection sensitivity are assumed to be the result of early and prolonged experiences of rejection. Aim of this study was to investigate autobiographical memories of rejection in clinical samples high in rejection sensitivity (Borderline Personality Disorder, BPD, and Major Depressive Disorder, MDD) and to identify group differences in the quality of the memories. Memories of rejection were retrieved using an adapted version of the Autobiographical Memory Test (AMT; five positive cue words, five cue words referring to rejection). Specificity of memories and linguistic word usage was analyzed in 30 patients with BPD, 27 patients with MDD and 30 healthy controls. Patients with BPD retrieved less specific memories compared to the healthy control group, whereas patients with MDD did not differ from controls in this regard. The group difference was no longer significant when controlling for rejection sensitivity. Linguistic analysis indicated that compared to both other groups, patients with BPD showed a higher self-focus, used more anger-related words, referred more frequently to social environments, and rated memories of rejection as more relevant for today's life. Clinical symptoms were not assessed in the control group. Moreover, the written form of the AMT might reduce the total number of specific memories. The level of rejection sensitivity influenced the specificity of the retrieved memories. Analysis of linguistic styles revealed specific linguistic patterns in BPD compared to non-clinical as well as depressed participants. Copyright © 2014 Elsevier Ltd. All rights reserved.

Objective Patients with rheumatoid arthritis (RA) are at increased risk of herpes zoster, and vaccination is recommended for patients ages 50 years and older, prior to starting treatment with biologic agents or tofacitinib. Tofacitinib is an oral JAK inhibitor for the treatment of RA. We evaluated its effect on the immune response and safety of live zoster vaccine (LZV). Methods In this phase II, 14‐week, placebo‐controlled trial, patients ages 50 years and older who had active RA and were receiving background methotrexate were given LZV and randomized to receive tofacitinib 5 mg twice daily or placebo 2–3 weeks postvaccination. We measured humoral responses (varicella zoster virus [VZV]–specific IgG level as determined by glycoprotein enzyme‐linked immunosorbent assay) and cell‐mediated responses (VZV‐specific T cell enumeration, as determined by enzyme‐linked immunospot assay) at baseline and 2 weeks, 6 weeks, and 14 weeks postvaccination. End points included the geometric mean fold rise (GMFR) in VZV‐specific IgG levels (primary end point) and T cells (number of spot‐forming cells/106 peripheral blood mononuclear cells) at 6 weeks postvaccination. Results One hundred twelve patients were randomized to receive tofacitinib (n = 55) or placebo (n = 57). Six weeks postvaccination, the GMFR in VZV‐specific IgG levels was 2.11 in the tofacitinib group and 1.74 in the placebo group, and the VZV‐specific T cell GMFR was similar in the tofacitinib group and the placebo group (1.50 and 1.29, respectively). Serious adverse events occurred in 3 patients in the tofacitinib group (5.5%) and 0 patients (0.0%) in the placebo group. One patient, who lacked preexisting VZV immunity, developed cutaneous vaccine dissemination 2 days after starting tofacitinib (16 days postvaccination). This resolved after tofacitinib was discontinued and the patient received antiviral treatment. Conclusion Patients who began treatment with tofacitinib 2–3 weeks after receiving LZV had VZV‐specific humoral and cell‐mediated immune responses to LZV similar to those in placebo‐treated patients. Vaccination appeared to be safe in all of the patients except 1 patient who lacked preexisting VZV immunity. PMID:28845577

To develop three prognostic groups for disease specific mortality based on the binary classified pretreatment variables age, haemoglobin concentration (Hb), erythrocyte sedimentation rate (ESR), alkaline phosphatase (ALP), prostate-specific antigen (PSA), plasma testosterone and estradiol level in hormonally treated patients with metastatic prostate cancer (PCa). The present study comprised 200 Finnprostate 6 study patients, but data on all variables were not known for every patient. The patients were divided into three prognostic risk groups (Rgs) using the prognostically best set of pretreatment variables. The best set was found by backward stepwise selection and the effect of every excluded variable on the binary classification cut-off points of the remaining variables was checked and corrected when needed. The best group of variables was ALP, PSA, ESR and age. All data were known in 142 patients. Patients were given one risk point each for ALP > 180 U/l (normal value 60-275 U/l), PSA > 35 microg/l, ESR > 80 mm/h and age < 60 years. Three risk groups were formed: Rg-a (0-1 risk points), Rg-b (2 risk points) and Rg-c (3-4 risk points). The risk of death from PCa increased statistically significantly with advancing prognostic group. Patients with metastatic PCa can be divided into three statistically significantly different prognostic risk groups for PCa-specific mortality by using the binary classified pretreatment variables ALP, PSA, ESR and age.

Computer-based decision support systems are a promising method for incorporating research evidence into clinical practice. However, evidence is still scant on how such information technology solutions work in primary healthcare when support is provided across many health problems. In Finland, we designed a trial where a set of evidence-based, patient-specific reminders was introduced into the local Electronic Patient Record (EPR) system. The aim was to measure the effects of such reminders on patient care. The hypothesis was that the total number of triggered reminders would decrease in the intervention group compared with the control group, indicating an improvement in patient care. From July 2009 to October 2010 all the patients of one health center were randomized to an intervention or a control group. The intervention consisted of patient-specific reminders concerning 59 different health conditions triggered when the healthcare professional (HCP) opened and used the EPR. In the intervention group, the triggered reminders were shown to the HCP; in the control group, the triggered reminders were not shown. The primary outcome measure was the change in the number of reminders triggered over 12 months. We developed a unique data gathering method, the Repeated Study Virtual Health Check (RSVHC), and used Generalized Estimation Equations (GEE) for analysing the incidence rate ratio, which is a measure of the relative difference in percentage change in the numbers of reminders triggered in the intervention group and the control group. In total, 13,588 participants were randomized and included. Contrary to our expectation, the total number of reminders triggered increased in both the intervention and the control groups. The primary outcome measure did not show a significant difference between the groups. However, with the inclusion of patients followed up over only six months, the total number of reminders increased significantly less in the intervention group than in the control group when the confounding factors (age, gender, number of diagnoses and medications) were controlled for. Computerized, tailored reminders in primary care did not decrease during the 12 months of follow-up time after the introduction of a patient-specific decision support system.

To explore if soluble amyloid precursor proteins (sAPP) in CSF improve the identification of patients with incipient Alzheimer disease (AD) in a group of patients with mild cognitive impairment (MCI). A cohort study with follow-up assessments of 58 patients with MCI with baseline CSF sampling was conducted: 21 patients had progressed to probable AD (MCI-AD), 27 still had MCI, 8 had reverted to normal (MCI-NAD), and 2 patients with frontotemporal dementia (FTD) were excluded. Sixteen additional patients with FTD were included to explore the specificity of the CSF markers. CSF concentrations of sAPPα, sAPPβ, tau, and Aβ(1-42) were measured with sensitive and specific ELISAs. Associations between diagnostic status, CSF protein concentrations, and other patient characteristics were explored using multiple logistic regression analyses with stepwise variable selection. The optimal sensitivity and specificity of the best models were derived from receiver operating characteristic curves. The MCI-AD group had significantly higher sAPPβ concentrations than the MCI-NAD and the FTD groups. A combination of sAPPβ, tau, and age differentiated the MCI-AD and the MCI-NAD groups with a sensitivity of 80.00% and a specificity of 81.00%. The best model for the differentiation of the MCI-AD and the FTD groups included sAPPβ and tau, and showed a sensitivity of 95.20% and a specificity of 81.20%. Aβ(1-42) and sAPPα did not significantly contribute to the models. These findings suggest that sAPPβ may be clinically useful, and superior to Aβ(1-42), in the early and differential diagnosis of incipient AD.

The purpose of this study was to evaluate the sensitivity, specificity and predictive value of thyrotropin receptor antibody (TRAb) in the diagnosis of Graves disease. TRAb was tested by an isotopic receptor assay-TRAK Henning-in 80 newly diagnosed, untreated Graves disease patients (group I), 63 with other thyroid diseases (group II) and 60 controls (group III). In group I, 11 patients were TRAb negative and 7 were considered in the gray area (TRAb between 9 and 14 U/L). In group II, only 2 patients had TRAb 9 U/l and all controls were TRAb negative. For statistical analysis patients with TRAb in gray area were excluded. Sensitivity and specificity for this assay were 84.5 and 100% respectively. Predictive value of 100% affords certainty that a hyperthyroid patient with a positive TRAb has Graves disease, not sequining a scintigram.

The knowledge of the specificity of cognitive biases in psychiatric disorders is important in order to develop disorder-specific cognitive models and therapies. This cross-sectional study aimed to investigate the specificity of jumping to conclusions (JTC) and attributional biases (AB) for patients with schizophrenia. Twenty patients with paranoid schizophrenia were compared with patients with depression (n=20) and with anorexia nervosa (n=15) and nonclinical controls (n=55). All participants were administered a modified version of the beads task (JTC), a revised German version of the Internal, Personal, and Situational Attributions Questionnaire (AB), and several symptom and neurocognitive measures. The proportion of patients with JTC bias in the schizophrenia group was, at the descriptive level, higher than in the depression and the anorexia groups. Regarding AB, the schizophrenia group showed a significantly stronger externalising but not personalising bias than the clinical control groups. Neither JTC nor attributional biases were significantly associated with delusions in general or persecutory delusion. We found evidence for the specificity of an externalising bias for paranoid schizophrenia. Concerning JTC bias the evidence was less clear. Whether the modification of those biases through psychological interventions would have an effect on psychopathology should be investigated in the context of clinical trials.

The purpose of this study was to evaluate the effects of 6 months of specific balance training included in endurance-resistance program on postural balance in haemodialysis (HD) patients. Forty-nine male patients undergoing HD were randomly assigned to an intervention group (balance training included in an endurance-resistance training, n = 26) or a control group (resistance-endurance training only, n = 23). Postural control was assessed using six clinical tests; Timed Up and Go test, Tinetti Mobility Test, Berg Balance Scale, Unipodal Stance test, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scale. All balance measures increased significantly after the period of rehabilitation training in the intervention group. Only the Timed Up and Go, Berg Balance Scale, Mini-Balance Evaluation Systems Test and Activities Balance Confidence scores were improved in the control group. The ranges of change in these tests were greater in the balance training group. In HD patients, specific balance training included in a usual endurance-resistance training program improves static and dynamic balance better than endurance-resistance training only. Implications for rehabilitation Rehabilitation using exercise in haemodialysis patients improved global mobility and functional abilities. Specific balance training included in usual endurance resistance training program could lead to improved static and dynamic balance.

Aim of this study is the evaluation of the impact of preoperative informative session using a Multimedia Health Educational Program (MHEP) on patients undergoing elective Laparoscopic Cholecystectomy (LC) for cholelithiasis, preoperative anxiety and postoperative pain and nausea. Sixty consecutive patients scheduled for elective LC were considered for enrollment in the trial. Patients were assigned randomly to four groups: Group A included 15 patients, preoperatively informed regarding LC through the MHEP presented by a Registered Nurse (RN). Group B included 15 patients preoperatively informed through a leaflet (designed and developed using the exact contents of the MHEP). In Group C, there were 15 patients who were being informed verbally from the RN. Finally, the control Group D included 15 patients, who had the conventional preoperative information about the operation and postoperative course by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, C. Preoperative assessment of patient's knowledge about cholelithiasis and LC was performed after informative session, and was based on a specifically developed "closed, true-false" questionnaire. Preliminary results suggest that conventional information provided by the attending surgeon (Group D) is inadequate. Specifically developed informative sessions with the contribution of MHEP seems to be effective on reducing preoperative anxiety and postoperative pain, in patients undergoing elective LC.

In recent years, several novel immunotherapeutic approaches were developed and investigated in patients with hepatocellular carcinoma (HCC). We designed this systematic review, to evaluate clinical efficacy of specific immunotherapy in patients with HCC, according to the guidelines of Border of Immune Tolerance Education and Research Network (BITERN) and Cochrane collaboration. We searched Medline, Scopus, CENTRAL, TRIP, DART, OpenGrey, and ProQuest through the 9th of December 2015. One author reviewed and retrieved citations from these seven databases for irrelevant and duplicate studies, and two other authors independently extracted data from the studies and rated their quality. We collated study findings and calculated a weighted treatment effect across studies using Review Manager. We found 12144 references in seven databases of which 21 controlled studies with 1885 HCC patients in different stages were included in this systematic review after the primary and secondary screenings. Overall, patients undergoing specific immunotherapy had significantly higher overall survival than those in control group (HR = 0.59; 95% CI = 0.47-0.76, P < 0.0001). There was a significant difference in recurrence-free survival between patients undergoing specific immunotherapy and patients in control groups and patients in immunotherapy groups overall had less recurrence than control group (HR = 0.54; 95% CI = 0.46-0.63, P < 0.00001). Results of this systematic review based on the available literature suggest that overall specific immunotherapeutic approaches could be beneficiary for the treatment of patients with HCC. This further supports the current and ongoing evaluations of specific immunotherapies in the field. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

To assess the risk factors for biochemical recurrence in D'Amico intermediate-risk prostate cancer patients treated using radical prostatectomy. We retrospectively reviewed the medical records of 1268 men with prostate cancer treated using radical prostatectomy without neoadjuvant therapy. The association between various risk factors and biochemical recurrence was then statistically evaluated. The Kaplan-Meier method, log-rank tests and Cox proportional hazards models were used for statistical analysis. In the intermediate-risk group, 96 patients (14.5%) experienced biochemical recurrence during a median follow up of 41 months. In the intermediate-risk group, preoperative prostate-specific antigen level, prostate volume and prostate-specific antigen density were significant preoperative risk factors for biochemical recurrence, whereas other factors including age, primary Gleason 4, clinical stage >T2 and percentage of positive biopsies were not. In multivariate analysis, higher preoperative prostate-specific antigen level and density, and a smaller prostate volume were independent risk factors for biochemical recurrence in the intermediate-risk group. Biochemical recurrence-free survival of patients in the intermediate-risk group with a higher prostate-specific antigen level and density (≥15 ng/mL, ≥0.6 ng/mL/cm(3), respectively), and lower prostate volume (≤10 mL) was comparable with that of high-risk group individuals (P = 0.632, 0.494 and 0.961, respectively). Preoperative prostate-specific antigen, prostate volume and prostate-specific antigen density are significant risk factors for biochemical recurrence in D'Amico intermediate-risk prostate cancer patients treated using radical prostatectomy. Using these variables, a subset of the intermediate-risk patients can be identified as having equivalent outcomes to high-risk patients. © 2015 The Japanese Urological Association.

The aim of this study was to determine whether local radiotherapy to the prostate by intraoperative radiotherapy (IORT) increases the overall and cancer-specific survival rates of patients with metastatic prostate cancer. Between 1993 and 2000, 102 patients with prostate cancer were treated with a combination of (a) IORT of the prostate (25 or 30 Gy per fraction); (b) external beam radiotherapy of the prostate (30 Gy in 10 fractions), starting approximately 1 week post-operatively; and (c) endocrine treatment. Of these, 16 patients had stage D1 disease (D1 IORT group), 32 had stage D2 disease without visceral metastasis (D2 IORT group), and 38 had stage D2 disease without visceral metastasis and did not receive local therapy (D2 control group). Overall and cancer-specific survival rates were compared. The 5- and 10-year cancer-specific survival rates were 75.9 and 52.7 %, respectively, in the (D1 + D2) IORT group and 45.8 and 33.5 %, respectively, in the D2 control group, with cancer-specific survival being significantly longer in the D2 IORT than in the D2 control group (P = 0.030). Univariate and multivariate reduced-rank regression analyses showed that extent of skeletal disease Grade 4 and non-regional lymph node metastasis were significantly prognostic of poorer cancer-specific survival (P < 0.001 each). Local radiotherapy to the prostate by IORT in patients with metastatic prostate cancer may contribute to better survival, especially in patients without extent of skeletal disease Grade 4 or non-regional lymph node metastasis.

Whether plantar fascia-specific stretching or shock-wave therapy is effective as an initial treatment for proximal plantar fasciopathy remains unclear. The aim of this study was to test the null hypothesis of no difference in the effectiveness of these two forms of treatment for patients who had unilateral plantar fasciopathy for a maximum duration of six weeks and which had not been treated previously. One hundred and two patients with acute plantar fasciopathy were randomly assigned to perform an eight-week plantar fascia-specific stretching program (Group I, n = 54) or to receive repetitive low-energy radial shock-wave therapy without local anesthesia, administered weekly for three weeks (Group II, n = 48). All patients completed the seven-item pain subscale of the validated Foot Function Index and a patient-relevant outcome questionnaire. Patients were evaluated at baseline and at two, four, and fifteen months after baseline. The primary outcome measures were a mean change in the Foot Function Index sum score at two months after baseline, a mean change in item 2 (pain during the first few steps of walking in the morning) on this index, and satisfaction with treatment. No difference in mean age, sex, weight, or duration of symptoms was found between the groups at baseline. At two months after baseline, the Foot Function Index sum score showed significantly greater changes for the patients managed with plantar fascia-specific stretching than for those managed with shock-wave therapy (p < 0.001), as well as individually for item 2 (p = 0.002). Thirty-five patients (65%) in Group I versus fourteen patients (29%) in Group II were satisfied with the treatment (p < 0.001). These findings persisted at four months. At fifteen months after baseline, no significant between-group difference was measured. A program of manual stretching exercises specific to the plantar fascia is superior to repetitive low-energy radial shock-wave therapy for the treatment of acute symptoms of proximal plantar fasciopathy.

The role of pathogen specific cellular immune responses against the eliciting pathogen in development of post-infectious chronic fatigue syndrome (PI-CFS) is not known and such studies are difficult to perform. The aim of this study was to evaluate specific anti-Giardia cellular immunity in cases that developed CFS after Giardia infection compared to cases that recovered well. Patients reporting chronic fatigue in a questionnaire study three years after a Giardia outbreak were clinically evaluated five years after the outbreak and grouped according to Fukuda criteria for CFS and idiopathic chronic fatigue. Giardia specific immune responses were evaluated in 39 of these patients by proliferation assay, T cell activation and cytokine release analysis. 20 Giardia exposed non-fatigued individuals and 10 healthy unexposed individuals were recruited as controls. Patients were clinically classified into CFS (n = 15), idiopathic chronic fatigue (n = 5), fatigue from other causes (n = 9) and recovered from fatigue (n = 10). There were statistically significant antigen specific differences between these Giardia exposed groups and unexposed controls. However, we did not find differences between the Giardia exposed fatigue classification groups with regard to CD4 T cell activation, proliferation or cytokine levels in 6 days cultured PBMCs. Interestingly, sCD40L was increased in patients with PI-CFS and other persons with fatigue after Giardia infection compared to the non-fatigued group, and correlated well with fatigue levels at the time of sampling. Our data show antigen specific cellular immune responses in the groups previously exposed to Giardia and increased sCD40L in fatigued patients.

Background: Kinesio Taping ® has been widely used in clinical practice. However, it is unknown whether this type of tape is more effective than placebo taping in patients with chronic lower back pain. Objective: To compare the effectiveness of Kinesio Taping ® in patients with chronic non-specific low back pain against a placebo tape and a control group. Method: This is a 3-arm, randomized controlled trial with a blinded assessor. Sixty patients with chronic non-specific low back pain were randomized into one of the three groups: Kinesio Taping ® group (n=20), Micropore® (placebo) group (n=20) and control group (n=20). Patients allocated to both the Kinesio Taping ® group and the placebo group used the different types of tape for a period of 48 hours. The control group did not receive any intervention. The outcomes measured were pain intensity (measured by an 11-point numerical rating scale) and disability (measured by the 24-item Roland Morris Disability Questionnaire). A blinded assessor measured the outcomes at baseline, 48 hours and 7 days after randomization. Results: After 48 hours, there was a statistically significant difference between the Kinesio Taping ® group versus the control group (mean between-group difference = -3.1 points, 95% CI=-5.2 to -1.1, p=0.003), but no difference when compared to the placebo group (mean between-group difference= 1.9 points, 95% CI=-0.2 to 3.9, p=0.08). For the other outcomes no differences were observed. Conclusions: The Kinesio Taping ® is not better than placebo (Micropore®) in patients with chronic low back pain. PMID:26647750

Background Invasive mucormycosis (IM) is an emerging life-threatening fungal infection. It is difficult to obtain a definite diagnosis and to initiate timely intervention. Mucorales-specific T cells occur during the course of IM and are involved in the clearance of the infection. We have evaluated the feasibility of detecting Mucorales-specific T cells in hematological patients at risk for IM, and have correlated the detection of such cells with the clinical conditions of the patients. Methods and Findings By using an enzyme linked immunospot assay, the presence of Mucorales-specific T cells in peripheral blood (PB) samples has been investigated at three time points during high-dose chemotherapy for hematologic malignancies. Mucorales-specific T cells producing interferon-γ, interleukin-10 and interleukin-4 were analysed in order to detect a correlation between the immune response and the clinical picture. Twenty-one (10.3%) of 204 patients, accounting for 32 (5.3%) of 598 PB samples, tested positive for Mucorales-specific T cells. Two groups could be identified. Group 1, including 15 patients without signs or symptoms of invasive fungal diseases (IFD), showed a predominance of Mucorales-specific T cells producing interferon-gamma. Group 2 included 6 patients with a clinical picture consistent with invasive fungal disease (IFD): 2 cases of proven IM and 4 cases of possible IFD. The proven patients had significantly higher number of Mucorales-specific T cells producing interleukin-10 and interleukin-4 and higher rates of positive samples by using derived diagnostic cut-offs when compared with the 15 patients without IFD. Conclusions Mucorales-specific T cells can be detected and monitored in patients with hematologic malignancies at risk for IM. Mucorales-specific T cells polarized to the production of T helper type 2 cytokines are associated with proven IM and may be evaluated as a surrogate diagnostic marker for IM. PMID:26871570

This study was undertaken for two reasons: 1) It is more difficult to diagnose hypersensitivity to molds than to other allergens, so an evaluation of diagnostic tests was needed. 2) Alternaria is the principal cause of mold sensitization in our area. Sixty-six patients (20 +/- 4 years) were selected and divided into two groups. Group A was made up of patients with rhinitis and/or asthma due to Alternaria sensitization. Group B consisted of patients sensitized to other allergens and patients with nonrespiratory allergic disorders. Skin tests (prick and intradermal), challenge tests (conjunctival, nasal, and bronchial), and specific IgE determination were performed for all patients. A biologically standardized extract of Alternaria tenuis (Alergia e Inmunología Abelló, S. A., Madrid, Spain) obtained from a single batch was used for all tests. Our diagnostic criterion was a clinical history of rhinitis or asthma that coincided with the results of nasal/bronchial challenge. The diagnostic value of the other tests was compared to this criterion. In the group of rhinitic patients, skin tests and conjunctival challenge were more sensitive than specific IgE determination. In asthmatic patients, the most sensitive techniques were nasal and conjunctival challenges, followed by prick and intradermal skin tests, and, lastly, serum specific IgE determination. When rhinitis and asthma were considered jointly, the most sensitive test was conjunctival challenge, followed by skin-prick and intradermal tests. All tests had the same specificity, regardless of disorder. Nasal challenge was positive in all patients. Skin tests are easy to perform, cheap, non-traumatic for the patient, and sufficiently specific and sensitive for the diagnosis of Alternaria hypersensitivity.(ABSTRACT TRUNCATED AT 250 WORDS)

Utilizing patient-specific instrumentation during total knee arthroplasty has gained popularity in recent years with theoretical advantages in blood loss, intraoperative time, length of stay, postoperative alignment, and functional outcome, amongst others. No study has compared acute perioperative measures between patient-specific instrumentation and conventional instrumentation in the bilateral total knee arthroplasty setting. We compared patient-specific instrumentation versus conventional instrumentation in the setting of bilateral total knee arthroplasty to determine any benefits in the immediate perioperative period including surgical time, blood loss, pain medication use, length of stay, and discharge disposition. A total of 49 patients with standard instrumentation and 31 patients with patient-specific instrumentation were retrospectively reviewed in a two-year period at one facility. At baseline, the groups were comparable with respect to age, ASA, BMI, and comorbid conditions. We analyzed data on operative time, blood loss, hemoglobin change, need for transfusion, pain medication use, length of stay, and discharge disposition. There was no statistically significant difference between groups in regards to these parameters. Patient-specific instrumentation in the setting of bilateral total knee arthroplasty did not provide any immediate perioperative benefit compared to conventional instrumentation.

Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.2 to 3.5 mm). The value of completion lymph-node dissection for patients with sentinel-node metastases is not clear. In an international trial, we randomly assigned patients with sentinel-node metastases detected by means of standard pathological assessment or a multimarker molecular assay to immediate completion lymph-node dissection (dissection group) or nodal observation with ultrasonography (observation group). The primary end point was melanoma-specific survival. Secondary end points included disease-free survival and the cumulative rate of nonsentinel-node metastasis. Immediate completion lymph-node dissection was not associated with increased melanoma-specific survival among 1934 patients with data that could be evaluated in an intention-to-treat analysis or among 1755 patients in the per-protocol analysis. In the per-protocol analysis, the mean (±SE) 3-year rate of melanoma-specific survival was similar in the dissection group and the observation group (86±1.3% and 86±1.2%, respectively; P=0.42 by the log-rank test) at a median follow-up of 43 months. The rate of disease-free survival was slightly higher in the dissection group than in the observation group (68±1.7% and 63±1.7%, respectively; P=0.05 by the log-rank test) at 3 years, based on an increased rate of disease control in the regional nodes at 3 years (92±1.0% vs. 77±1.5%; P<0.001 by the log-rank test); these results must be interpreted with caution. Nonsentinel-node metastases, identified in 11.5% of the patients in the dissection group, were a strong, independent prognostic factor for recurrence (hazard ratio, 1.78; P=0.005). Lymphedema was observed in 24.1% of the patients in the dissection group and in 6.3% of those in the observation group. Immediate completion lymph-node dissection increased the rate of regional disease control and provided prognostic information but did not increase melanoma-specific survival among patients with melanoma and sentinel-node metastases.

To evaluate (I) trastuzumab-containing primary systemic therapy (PST) in human epidermal growth factor receptor 2 (Her2) overexpressing breast carcinomas.; (II) compare the patients who achieved and those who did not achieve pathological complete remission (pCR), and (III) analyze the accuracy of different clinical-imaging modalities in tumor response monitoring. 188 patients who received PST between 2008 and 2014 were reviewed and 43 Her2 overexpressing breast cancer patients (28 Luminal B/Her2-positive and 15 Her2-positive) were enrolled. 26 patients received mostly taxane-based PST without trastuzumab (Group 1) and 17 patients received trastuzumab-containing PST (Group 2). We compared the concordance between pCR and complete remission (CR) defined by breast-ultrasound, CR defined by standard 18F-fluoro-deoxy-glucose positron emission tomography and computerized tomography (FDG-PET/CT) criteria (Method 1) and CR defined by a novel, breast cancer specific FDG-PET/CT criteria (Method 2). Sensitivity (sens), specificity (spec), and positive (PPV) and negative predictive values (NPV) were calculated. Ten patients (38.5%) in Group 1 and eight (47%) in Group 2 achieved pCR. pCR was significantly more frequent in Her2-positive than in Luminal B/Her2-positive tumors in both Group 1: (P=0.043) and Group 2: (P=0.029). PET/CT evaluated by the breast cancer specific criteria (Method 2) differentiated pCR from non-pCR more accurately in both groups (Group 1: sens=77.8%, spec=%, PPV=100%, NPV=71.4%; Group 2: sens=87.5%, spec=62.5%, PPV=70%, NPV=83.3%) than standard PET/CT criteria (Method 1) (Group 1: sens=22.2% spec=100% PPV=100% NPV=41.7%; in Group 2: sens=37.5%, spec=87.5%, PPV=75% NPV=58.3%) or breast ultrasound (Group 1, sens=83.3% spec=25% PPV=62.5% NPV=50%; Group 2, sens=100% spec=12.5% PPV=41.6% NPV=100%). The benefit of targeted treatment with trastuzumab-containing PST in Her2 overexpressing breast cancer was defined in terms of pCR rate. Luminal B/Her2-positive subtype needs further subdivision to identify patients who would benefit from PST. Combined evaluation of tumor response by our novel, breast cancer specific FDG-PET/CT criteria accurately differentiated pCR from non-pCR patients.

To assess the significance of serum total prostate specific antigen (tPSA) and digital rectal examination (DRE) in the diagnosis of prostate cancer (PC). One hundred and eighteen patients with serum tPSA ranging between 2.5 and 10 ng/ml with lower urinary tract symptoms presented at the Urology Clinic of Soba University Hospital, Khartoum, Sudan from August 2008 and January 2010 were included in the study. Serum tPSA was measured using enzyme immunoassay method, and accordingly, the patients were classified into 2 groups: patients that had tPSA between 2.5-4.0 ng/ml; and patients that had tPSA between 4.1-10 ng/ml. The DRE was performed on all patients by a qualified urologist, and were recorded as a group with suspicion of PC, and a group with no suspicion of PC. All patients underwent transrectal sextant prostate biopsy. The DRE alone showed 63.8% sensitivity and 68% specificity with 46.9% positive predictive value (PPV) for the diagnosis of PC. The tPSA test revealed 91.6% sensitivity and 24% specificity with PPV of 34%. However, when combining DRE and tPSA, the sensitivity reached 100% and the specificity increased to 92% with PPV of 49%. Combining DRE and tPSA test increases the sensitivity, specificity, and PPV of PC detection.

The high rate of cannabis use among patients with first-episode psychosis (FEP), as well as the associated negative impact on illness course and treatment outcomes, underlines the need for effective interventions in these populations. However, to date, there have been few clinical treatment trials (of pharmacological or psychological interventions) that have specifically focused on addressing comorbid cannabis use among these patients. The aim of this paper is to describe the design of a study protocol for a randomized controlled trial in which the objective is to assess the efficacy of a specific cognitive behavioral therapy program for cannabis cessation in patients with FEP compared to standard treatment (psychoeducation). This is a single-blind randomized study with 1 year of follow-up. Patients are to be randomly assigned to one of two treatments: (1) specific cognitive behavioral therapy for cannabis cessation composed of 1-hour sessions once a week for 16 weeks, in addition to pharmacological treatment scheduled by the psychiatrist, or (2) a control group (psychoeducation + pharmacological treatment) following the same format as the experimental group. Participants in both groups will be evaluated at baseline (pre-treatment), at 16 weeks (post-treatment), and at 3 and 6 months and 1 year of follow-up. The primary outcome will be that patients in the experimental group will have greater cannabis cessation than patients in the control group at post-treatment. The secondary outcome will be that the experimental group will have better clinical and functional outcomes than the control group. This study provides the description of a clinical trial design based on specific cognitive behavioral therapy for cannabis cessation in FEP patients, aiming to improve clinical and functional outcome, as well as tackling the addictive disorder.

According to literature, virtual reality was found to reduce pain and kinesiophobia in patients with chronic pain. The purpose of the study was to investigate short-term effect of the virtual reality on pain, function, and kinesiophobia in patients with subacute and chronic non-specific low-back pain METHODS: This randomised controlled study in which 44 patients were randomly assigned to the traditional physiotherapy (control group, 22 subjects) or virtual walking integrated physiotherapy (experimental group, 22 subjects). Before and after treatment, Visual Analog Scale (VAS), TAMPA Kinesiophobia Scale (TKS), Oswestry Disability Index (ODI), Nottingham Health Profile (NHP), Timed-up and go Test (TUG), 6-Minute Walk Test (6MWT), and Single-Leg Balance Test were assessed. The interaction effect between group and time was assessed by using repeated-measures analysis of covariance. After treatment, both groups showed improvement in all parameters. However, VAS, TKS, TUG, and 6MWT scores showed significant differences in favor of the experimental group. Virtual walking integrated physiotherapy reduces pain and kinesiophobia, and improved function in patients with subacute and chronic non-specific low-back pain in short term.

Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

To identify potential subgroups amongst patients with non-specific low back pain based on a consensus list of potentially discriminatory examination items. Exploratory study. A convenience sample of 106 patients with non-specific low back pain (43 males, 63 females, mean age 36 years, standard deviation 15.9 years) and 7 physiotherapists. Based on 3 focus groups and a two-round Delphi involving 23 health professionals and a random stratified sample of 150 physiotherapists, respectively, a comprehensive examination list comprising the most "discriminatory" items was compiled. Following reliability analysis, the most reliable clinical items were assessed with a sample of patients with non-specific low back pain. K-means cluster analysis was conducted for 2-, 3- and 4-cluster options to explore for meaningful homogenous subgroups. The most clinically meaningful cluster was a two-subgroup option, comprising a small group (n = 24) with more severe clinical presentation (i.e. more widespread pain, functional and sleeping problems, other symptoms, increased investigations undertaken, more severe clinical signs, etc.) and a larger less dysfunctional group (n = 80). A number of potentially discriminatory clinical items were identified by health professionals and sub-classified, based on a sample of patients with non-specific low back pain, into two subgroups. However, further work is needed to validate this classification process.

To investigate the effects of a Pilates exercise program on disability, pain, lumbar mobility, flexibility and balance in patients with chronic non-specific low back pain. Randomized controlled trial. University laboratory. A total of 54 patients with chronic non-specific low back pain. Patients were randomly allocated to an experimental group ( n=27) included in a Pilates exercise program or to a control group ( n=27) receiving information in a form of a leaflet. Disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), current, average and pain at it least and at its worst (Visual Analogue Scales), lumbar mobility (modified Shober test), flexibility (finger-to-floor test) and balance (single limb stance test) were measured at baseline and after the intervention. A between-group analysis showed significant differences in the intervention group compared to the control group for both disability scores, the Rolland-Morris questionnaire (mean change±standard deviation of 5.31±3.37 and 2.40±6.78 respectively and between-groups mean difference of 3.2 ± 4.12, p=0.003) and the Oswestry Disability Index ( p<0.001), current pain ( p=0.002) and pain at it least ( p=0.033), flexibility (0.032) and balance (0.043). An 8-week Pilates exercise program is effective in improving disability, pain, flexibility and balance in patients with chronic non-specific low back pain.

Cognitive and Affective Uses of a Thoracic Outlet Syndrome Facebook Support Group.

There are currently many disease-specific groups on Facebook in which patients may take an active part (Greene, Choudhry, Kilabuk, & Shrank, 2011). Although uses and gratifications of patient-disease groups have begun to be identified for chronic diseases, rare diseases have been omitted, even though they collectively affect roughly 30 million people in the United States and 350 million people worldwide. This study is a content analysis of one Facebook rare disease patient group, the Thoracic Outlet Syndrome (TOS) Awareness group. All wall posts were recorded and content analyzed for cognitive and affective categories and subcategories between October 9, 2011 (date of site origin), and May 1, 2012. Analysis of cognitive needs indicated TOS patients used the site more to share information about their own TOS symptoms and journey with diagnosis than to seek information. Analysis of affective needs found patients were more likely to use the site to give support and encouragement to others than to express concerns and complaints. The complaints they did express were primarily related to their frustration with the general medical community's perceived inability to diagnose and understand their disease or to question a specific doctor's diagnosis/recommendation. Results point to needs specific to TOS patients that uses and gratifications research can help clarify.

Cephalosporin and penicillin cross-reactivity in patients allergic to penicillins.

Bata-lactam antibiotics are the most commonly used antibiotics which usually cause serious IgE-mediated allergic reactions. Of all bata-lactam antibiotics, penicillins have so far been the best-studied, but the studies of cephalosporins and their cross-reactivity with penicillins are rare. We sought to evaluate the IgE response in vitro and estimate cross-reactivity between penicillins and cephalosporins in patients allergic to penicillins. We studied 87 control subjects and 420 subjects allergic to penicillins. Radioallergosorbent test (RAST) was performed to detect eight types of specific-penicillin IgE and eleven types of specific-cephalosporin IgE. The cross-reactivity and different molecules recognition by IgE were studied with a radioallergosorbent inhibition test. Of 420 patients allergic to penicillins, 95 patients (22.62%) showed specific-cephalosporin IgE positive, 73 patients (17.38%) showed IgEs positive to both penicillins and cephalosporins. In specific-penicillin IgE positive group, the positive rate of specific-cephalosporin IgE was significantly higher than in specific-penicillin IgE negative group (27.14% vs. 14.57%, p < 0.01). In urticaria group, the positive rate of specific-cephalosporin IgE was significantly higher than in other symptoms group (30.65% vs. 8.11%, p < 0.05). The analysis of drugs which have the same or similar side-chains showed that benzylpenicillanyl-IgE (BPA-IgE), ampicillanyl-IgE (APA-IgE), amoxicillanyl-IgE (AXA-IgE) were respectively related to cephalothanyl-IgE (CLA-IgE), cephalexanyl-IgE (CEXA-IgE), cephalexanyl-IgE (CEXA-IgE)in sera of penicillin-allergic patients we studied, and compared with patients who had negative amoxicillin-IgE, the positive rates of specific-ampicillin IgE and specific-cephalexin IgE were significantly higher in patients who had positive amoxicillin-IgE (14.43% vs. 3.72%, 14.00% vs. 2.96%, p < 0.01). Radioallergosorbent test and radioallergosorbent inhibition test confirmed that both nuclear structure and R1 side-chain contribute to IgE recognition. There exists cross-reactivity between cephalosporins and penicillins; patients allergic to several penicillins are more likely to develop allergic reaction to cephalosporins; due to sensitization to the similar structural characteristics (nuclear and R1 side-chain), penicillin-allergic patients may develop cross-allergic reactions with not only first-generation but also third-generation cephalosporins.

The clinical spectrum of ocular disease in 37 patients with atopic keratoconjunctivitis (AKC) is described. Patients typically had a severe blepharoconjunctivitis. Associated corneal scarring, suppurative keratitis, or keratoconus were the major causes of visual loss. Serum and tear samples from these patients were analyzed to quantify total and specific IgE antibodies. The results were compared as a case control study with results from samples from 55 patients with other forms of atopic disease and 16 nonatopic volunteers. Although the mean values for total and specific IgEs in the serum of patients with atopic disease were markedly higher than the values from nonatopic controls (P less than 0.00002), a difference between the disease groups could not be demonstrated (P greater than 0.05). There were also differences between both the total IgE (P = 0.0002) and pollen-specific IgE (P = 0.015) in tears from patients with atopic disease and nonatopic controls, but not for house dust mite or cat dander-specific IgEs. These results suggest that clinical differences between groups of patients with chronic allergic external eye disease are not associated with specific patterns of IgE production.

Transdiagnostic psychotherapies are designed to apply the same underlying treatment principles across a set of psychiatric disorders, without significant tailoring to specific diagnoses. Several transdiagnostic psychotherapy protocols have been developed recently, each of which has its own strengths and weaknesses. One promising treatment is Transdiagnostic Behaviour Therapy (TBT), in that it is one of the few transdiagnostic treatments to date shown to be effective in patients with depressive and anxiety disorders. However, TBT has only been investigated via individual psychotherapy. The present study investigated the effectiveness of a group protocol for TBT, compared with disorder-specific group psychotherapies, in a naturalistic setting. 109 participants with various diagnoses of affective disorders completed either group TBT (n = 37) or a disorder-specific group psychotherapy (n = 72). Measures included assessments of psychiatric symptomatology and transdiagnostic impairment at baseline and post-treatment. Overall, participants in the TBT group demonstrated significant improvements across all measures. When compared with disorder-specific groups, no statistical differences were observed between groups across symptoms; however, participants in the TBT group demonstrated roughly twice the treatment effect sizes in transdiagnostic impairment compared with participants in the disorder-specific groups. In addition, when participants from the most well-represented diagnosis and disorder-specific treatment (social anxiety disorder) were investigated separately, participants in the TBT group demonstrated significantly larger improvements in comorbid depressive symptoms than participants in the disorder-specific treatment. Pending replication and additional comparison studies, group TBT may provide an effective group treatment option for patients with affective disorders.

The recovery of mediator metabolites from urine has the potential to provide a rapid, safe, and easily available index of release of mediators. We aimed to determine urinary metabolites of both histamine and leukotrienes (LTs) in patients affected by chronic urticaria (CU). Twenty patients with CU were studied. They were selected on the basis of double-blind placebo-controlled challenge (DBPC) with acetyl salicylic acid (ASA) and food additives. Ten patients (group B) were negative to both challenges. Ten patients (group C) presented urticaria and/or the appearance of angioedema during or 24 h after challenge, with reactions to ASA (five patients) or food additives (five patients). We recruited 15 healthy volunteers as controls (group A). During a second challenge, groups B and C were challenged double-blind with a single dose of ASA, or a specific food additive, or placebo. The healthy group was challenged only with a placebo (talc capsule). Patients in groups B and C were challenged twice: with placebo (as groups B1 and C1) and with ASA (groups B2 and C2) or food additives (C2). Four samples of urine were collected; one during the night before the specific or sham challenge (baseline), and three at 2, 6 and 24 h after the challenge. Urinary methylhistamine (N-MH) and LTE4 were analyzed and normalized for urinary creatinine. For urinary N-MH at baseline, there was a significant difference only between group A and groups B1, B2, C1 and C2 (A vs. B1, P < 0.0001; A vs. B2, P < 0.0001; A vs. C1, P < 0.0001; A vs. C2, P < 0.0001). We detected a significant variation in urinary methylhistamine excretion only in group C2 after 2 h, 6 h and 24 h (P < 0.0001). However, no variations were observed in N-MH excretion rate in the other groups (A, B1, C1) after challenge with placebo, and in B2 after challenge with ASA 20 mg. For urinary LTE4 at baseline no differences were found between the mean values for the different groups. After specific challenge, only C2 patients showed significantly increased excretion rates of urinary LTE4 compared with the other groups challenged with placebo (A, B1, C1), or ASA (B2) (P < 0.0001). No significant correlation was seen between urinary LTE4 and methylhistamine excretion rate in any patients. Our results show that urinary excretion of N-MH and LTE4 is different for CU patients without ASA or food hypersensitivity, compared to those with CU with ASA or food additive hypersensitivity after specific challenge.

According to the Dutch Guideline on Hereditary Colorectal Cancer published in 2008, patients with recently diagnosed colorectal cancer (CRC) should undergo microsatellite instability (MSI) testing by a pathologist immediately after tumour resection if they are younger than 50 years, or if a second CRC has been diagnosed before the age of 70 years, owing to the high risk of Lynch syndrome (MIPA). The aim of the present MIPAPS study was to investigate general distress and cancer-specific distress following MSI testing. From March 2007 to September 2009, 400 patients who had been tested for MSI after newly diagnosed CRC were recruited from 30 Dutch hospitals. Levels of general distress (SCL-90) and cancer-specific distress (IES) were assessed immediately after MSI result disclosure (T1) and 6 months later (T2). Response rates were 23/77 (30%) in the MSI-positive patients and 58/323 (18%) in the MSI-negative patients. Levels of general distress and cancer-specific distress were moderate. In the MSI-positive group, 27% of the patients had high general distress at T1 versus 18% at T2 (p = 0.5), whereas in the MSI-negative group, these percentage were 14 and 18% (p = 0.6), respectively. At T1 and T2, cancer-specific distress rates in the MSI-positive group and MSI-negative group were 39 versus 27% (p = 0.3) and 38 versus 36% (p = 1.0), respectively. High levels of general distress were correlated with female gender, low social support and high perceived cancer risk. Moderate levels of distress were observed after MSI testing, similar to those found in other patients diagnosed with CRC. Immediately after result disclosure, high cancer-specific distress was observed in 40% of the MSI-positive patients.

To evaluate the applicability and accuracy of the urine lipoarabinomannan (LAM) test in tuberculosis (TB)/HIV co-infected patients and HIV-negative patients with disseminated TB. Frozen urine samples obtained at baseline from patients in the TB research cohort with proven culture-positive TB were selected for blinded urine LAM testing. One hundred and nine patients were categorized into four groups: (1) HIV-positive patients with TB; (2) HIV-negative patients with disseminated TB; (3) HIV-negative immunocompromised patients with TB; and (4) patients with diseases other than TB. The sensitivity of urine LAM testing for culture-positive TB, specificity of urine LAM testing for patients without TB, positive predictive value (PPV), and negative predictive value (NPV) were assessed. The sensitivity of the urine LAM test in group 1 patients with a CD4 T-cell count of >100, ≤100, and ≤50 cells/mm 3 was 38.5%, 40.6%, and 45%, respectively. The specificity and PPV of the urine LAM test were >80%. The sensitivity of the test was 20% in group 2 and 12.5% in group 3, and the specificity and PPV were 100% for both groups. A positive urine LAM test result was significantly associated with death. This promising diagnostic tool could increase the yield of TB diagnosis and may predict the mortality rate of TB infection, particularly in TB/HIV co-infected patients.

Earlier, we showed that neuropathic complications limit social participation of ex-leprosy patients, even in a non-endemic leprosy setting like the Netherlands. Self-care groups for ex-leprosy patients can strengthen self-worth of participants, prevent further handicap, and enable the exchange of coping strategies. For non-endemic leprosy settings with a very low rate of leprosy patients, a self-care group exclusively for (ex)leprosy patients is not likely to be feasible. A combined group with patients facing comparable morbidity would be more efficient than disease-specific self-care groups. Here, we studied the comparability in social constraints of diabetic patients and ex-leprosy patients. Moreover, we investigated if combined self-care groups for ex-leprosy patients and diabetic patients would be desirable and acceptable for possible participants. Social participation was studied based on in-depth interviews and Participation Scale information collected from 41 diabetic patients and compared with the data of 31 ex-leprosy patients from a prior study. Moreover, we made an inventory of potential strengths and limitations and attitudes toward combined self-care groups for diabetic patients with neuropathy. The following themes emerged among diabetic patients: disease confrontation, dependency, conflict with partner or relatives, feelings of inferiority, stigma, abandoning social activities, fear of the future, lack of information, and hiding the disease. These themes were very similar to those voiced by the previously interviewed ex-leprosy patients. The latter more often mentioned stigma and disease ignorance among Dutch health care workers. Whereas ex-leprosy patients perceived stigma on multiple fronts, diabetic patients only mentioned feeling inferior. Diabetic patients experienced some form of participation restriction in 39% of the cases as opposed to 71% of the ex-leprosy patients. Diabetic patients did acknowledge the comparability with leprosy as far as their neuropathic complaints concerned. Yet only 17% showed interest in combined self-care groups. The majority preferred disease-specific self-care groups only focused on diabetic patients. This might have been caused partly by the perception that a self-care group is yet another disease-related demand on their time, rather than an opportunity to become less dependent on health care services. The physical complications and social problems in ex-leprosy and diabetic patients with neuropathy are similar. Both groups show social participation limitations, yet in contrast to diabetic patients, ex-leprosy patients perceive stigma in more domains in life. Despite the fact that diabetic patients preferred disease-specific, homogeneous self-care groups, we believe that the option of combined groups with ex-leprosy patients and possibly even other people needing chronic wound care is a promising strategy. Therefore, further research is warranted into the acceptance and impact of self-care groups as a strategy to reduce social constraints by diseases causing neuropathy.

Transdiagnostic Cognitive Behavior Therapy (TCBT) manuals delivered in individual format have been reported to be just as effective as traditional diagnosis specific CBT manuals. We have translated and modified the "The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders" (UP-CBT) for group delivery in Mental Health Service (MHS), and shown effects comparable to traditional CBT in a naturalistic study. As the use of one manual instead of several diagnosis-specific manuals could simplify logistics, reduce waiting time, and increase therapist expertise compared to diagnosis specific CBT, we aim to test the relative efficacy of group UP-CBT and diagnosis specific group CBT. The study is a partially blinded, pragmatic, non-inferiority, parallel, multi-center randomized controlled trial (RCT) of UP-CBT vs diagnosis specific CBT for Unipolar Depression, Social Anxiety Disorder and Agoraphobia/Panic Disorder. In total, 248 patients are recruited from three regional MHS centers across Denmark and included in two intervention arms. The primary outcome is patient-ratings of well-being (WHO Well-being Index, WHO-5), secondary outcomes include level of depressive and anxious symptoms, personality variables, emotion regulation, reflective functioning, and social adjustment. Assessments are conducted before and after therapy and at 6 months follow-up. Weekly patient-rated outcomes and group evaluations are collected for every session. Outcome assessors, blind to treatment allocation, will perform the observer-based symptom ratings, and fidelity assessors will monitor manual adherence. The current study will be the first RCT investigating the dissemination of the UP in a MHS setting, the UP delivered in groups, and with depressive patients included. Hence the results are expected to add substantially to the evidence base for rational group psychotherapy in MHS. The planned moderator and mediator analyses could spur new hypotheses about mechanisms of change in psychotherapy and the association between patient characteristics and treatment effect.

We investigated the relationship between potentially pathogenic antibodies against a Trypanosoma cruzi ribosomal protein (P2β) and the evolution of Chagas disease and the effect of trypanocidal treatment on these variables. Seventy-eight patients with chronic Chagas disease who were followed-up for more than 20 years were divided into three groups: 30 asymptomatic persons undergoing specific treatment (group A), 37 asymptomatic persons not undergoing specific treatment (group B), and 11 patients with chronic chagasic cardiomyopathy (CCC) who were not treated. Five patients in group B showed evolution to myocardial abnormalities. Among persons with CCC, six showed no changes; the remaining persons showed progression of cardiac involvement. Levels of antibodies to P2β in persons in group A decreased from their initial values. This finding was not observed in persons in groups B and C. Comparisons at the end of the follow-up showed lower amounts of antibodies to P2β in groups A and C. These findings support the benefits of specific treatment during chronic infection. PMID:21460013

Diagnosis of tuberculosis (TB) is not always easy, thus employing methods with a short duration and acceptable sensitivity and specificity is necessary to diagnose TB. The aim of this study was to investigate the diagnostic value of serum adenosine deaminase (ADA) level for diagnosis of pulmonary tuberculosis. A total of 160 sex and age-matched subjects were included in this study, and were divided to four groups; forty patients with pulmonary tuberculosis (PTB) diagnosed based on the national TB program (NTP), forty patients with non-tuberculosis bacterial pneumonia, forty patients with lung cancer and forty people who were healthy in every respect. Serum adenosine deaminase activity in patients of each group was measured by the Giusti and Galanti calorimetry method using a commercial kit (Diazyme, USA). The ANOVA analysis was used to compare groups for quantitative variables. Mean serum ADA level in the PTB group was clearly higher than the mean serum ADA in the other three groups. Mean serum ADA was 26 IU/L in PTB patients, 19.48 IU/L in patients with pneumonia, 15.8 IU/L in patients with lung cancer, and 10.7 IU/L in the control group (P < 0.05). In regard to the cut off value of 26 IU/L for ADA in patients with PTB sensitivity and specificity was defined as 35% and 91%, respectively. Serum ADA activity with high specificity percentage may be a useful alternative test in restricted resource areas to rule out diagnosis of PTB. However, serum ADA activity is not a useful tool for TB diagnosis.

Beekeepers are strongly exposed to honey bee stings and therefore at an increased risk to develop IgE-mediated allergy to bee venom. We wondered whether bee venom-allergic beekeepers were different from normally exposed bee venom-allergic patients with regard to clinical and immunological parameters as well as their response to venom immunotherapy. Among the 459 bee venom-allergic patients seen over the 5 year period 1987-91, 62 (14%) were beekeepers and 44 (10%) family members of beekeepers. These two groups were compared with 101 normally exposed bee venom-allergic patients matched with the allergic beekeepers for age and sex, regarding clinical parameters, skin sensitivity, specific IgE and IgG antibodies to bee venom as well as safety and efficacy of venom immunotherapy. As expected, allergic beekeepers had been stung most frequently before the first allergic reaction. The three groups showed a similar severity of allergic symptoms following bee stings and had an equal incidence of atopic diseases. Allergic beekeepers showed higher levels of bee venom-specific serum IgG, lower skin sensitivity and lower levels of bee venom specific serum IgE than bee venom-allergic control patients. A negative correlation between number of stings and skin sensitivity as well as specific IgE was found in allergic beekeepers and their family members, while the number of stings was positively correlated with specific IgG in these two groups. Venom immunotherapy was equally effective in the three groups, but better tolerated by allergic beekeepers than the two other groups. The majority of allergic beekeepers continued bee-keeping successfully under the protection of venom immunotherapy. The lower level of sensitivity in diagnostic tests and the better tolerance of immunotherapy in allergic beekeepers is most likely related to the high level of specific IgG in this group.

Cognitive-behavioral therapy is frequently indicated for panic disorder. The aim here was to evaluate the efficacy of a model for cognitive-behavioral therapy for treating panic disorder with agoraphobia. Randomized clinical trial at Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro. A group of 50 patients with a diagnosis of panic disorder with agoraphobia was randomized into two groups to receive: a) cognitive-behavioral therapy with medication; or b) medication (tricyclic antidepressants or selective serotonin reuptake inhibitors). Although there was no difference between the groups after the treatment in relation to almost all variables with the exception of some items of the Sheehan disability scale and the psychosocial and environmental problems scale, the patients who received the specific therapy presented significant reductions in panic attacks, anticipatory anxiety, agoraphobia avoidance and fear of body sensations at the end of the study, in relation to the group without the therapy. On the overall functioning assessment scale, overall wellbeing increased from 60.8% to 72.5% among the patients in the group with therapy, thus differing from the group without therapy. Although both groups responded to the treatment and improved, we only observed significant differences between the interventions on some scales. The association between specific cognitive-behavioral therapy focusing on somatic complaints and pharmacological treatment was effective among this sample of patients with panic disorder and the response was similar in the group with pharmacological treatment alone.

The aim of this study was to compare the sensitivity and specificity of two questionnaires to identify patients with obstructive sleep apnea (OSA). Fifty-three moderate to severe OSA patients [with a respiratory disturbance index (RDI) ≥ 15] and 31 controls (RDI < 15) based on ambulatory somnographic assessment were recruited through flyers and mail at USC School of Dentistry. Each patient answered the Berlin and apnea risk evaluation system (ARES) questionnaires. The responses to the questionnaires were scored and compared for significant group differences. Moderate and severe OSA patients were predominantly male, older, had a larger neck size, and larger body mass index than controls. There were no significant differences in race or ethnicity between the two groups. In this study, subjects having a "high risk" ARES questionnaire were 7.9 times as likely to have OSA as subjects with "low or no risk" score (p = 0.0002). The ARES questionnaire had a sensitivity of 90.6%, specificity of 43.2%, a positive predictive value (PPV) of 73.8%, and negative predictive value (NPV) of 73.7% compared to 67.9%, 54.8%, 72%, and 50%, respectively, for the Berlin questionnaire using a cut point of RDI ≥ 15. In this specific patient group, not uncommon to the regular dental private practice, the ARES questionnaire performed better than the Berlin questionnaire with higher sensitivity, similar PPV, higher NPV, but lower specificity. The lower specificity could be explained in part because the ARES has been tailored to screen patients with an RDI ≥ 5, and our study included mostly mild to severe patients. In conclusion, in this specific group of subjects, the ARES questionnaire is a better choice than the Berlin questionnaire; however, the Berlin questionnaire is publicly available and the ARES screener is proprietary.

The purpose of this study was to determine the effectiveness of an individualized physical therapy intervention in treating neck pain based on a clinical reasoning algorithm. Treatment effectiveness was examined by assessing changes in impairment, physical performance, and disability in response to intervention. One treatment group of 30 patients with neck pain completed physical therapy treatment. The control group of convenience was formed by a cohort group of 27 subjects who also had neck pain but did not receive treatment for various reasons. There were no significant differences between groups in demographic data and the initial test scores of the outcome measures. A quasi-experimental, nonequivalent, pretest-posttest control group design was used. A physical therapist rendered an eclectic intervention to the treatment group based on a clinical decision-making algorithm. Treatment outcome measures included the following five dependent variables: cervical range of motion, numeric pain rating, timed weighted overhead endurance, the supine capital flexion endurance test, and the Patient Specific Functional Scale. Both the treatment and control groups completed the initial and follow-up examinations, with an average duration of 4 wk between tests. Five mixed analyses of variance with follow-up tests showed a significant difference for all outcome measures in the treatment group compared with the control group. After an average 4 wk of physical therapy intervention, patients in the treatment group demonstrated statistically significant increases of cervical range of motion, decrease of pain, increases of physical performance measures, and decreases in the level of disability. The control group showed no differences in all five outcome variables between the initial and follow-up test scores. This study delineated algorithm-based clinical reasoning strategies for evaluating and treating patients with cervical pain. The algorithm can help clinicians classify patients with cervical pain into clinical patterns and provides pattern-specific guidelines for physical therapy interventions. An organized and specific physical therapy program was effective in improving the status of patients with neck pain.

Stroke patients have major problems with impaired upper-extremity function. Unfortunately, many patients do not experience a full recovery from movement deficits in the upper extremities. The purpose of this study was to compare the effectiveness of inter-limb learning transfer (ILT) to the contralateral upper limb after both hemisphere-specific and -unspecific ipsilateral upper limb training for stroke patients with hemiparesis. Twenty-four stroke patients with hemiparesis participated. The hemisphere-specific training group performed reaching movements in a customized training setting in which non-dominant limb training participants began from a single starting location and proceeded to one of three target locations (1S3T condition); the dominant limb training participants started from one of three starting locations and proceeded to a single target location (3S1T condition). The hemisphere-unspecific training group performed these movements starting under reverse-start and target conditions. The non-dominant to dominant limb transfer, the hemisphere-specific training group performance time decreased significantly as compared with the pre-training session (p < 0.05). Also, the isolation contraction ratio was decreased significantly from that of the pre-training session in the biceps brachii muscles and increased significantly in the upper trapezius muscles (p < 0.05). And, dominant to non-dominant limb transfer in the hemisphere-specific training group significantly increased RMS amplitudes from the pre-training session in the biceps brachii and triceps muscles (p < 0.05). Also, the isolation contraction ratio was increased significantly from that of the pre-training session in the biceps brachii muscles and decreased significantly in the upper trapezius muscles (p < 0.05). However, the hemisphere-unspecific training group showed no significant differences in inter-limb learning transfer (ILT). The transfer of hemisphere-specific training from one arm to the other had a more positive influence on functional recovery than did hemisphere-unspecific training for patients with stroke and hemiparesis.

Significant rates of psychological distress occur in implantable cardioverter defibrillator (ICD) patients. Research has demonstrated that women are particularly at risk for developing distress and warrant psychosocial attention. The major objectives were to implement and test the effectiveness of a female-specific psychosocial group intervention on disease-specific quality of life outcomes in outpatient female ICD recipients versus a wait-list control group. Twenty-nine women were recruited for the study. Fourteen women were randomized to the intervention group and participated in a psychosocial intervention focused on female-specific issues; 15 were randomized to the wait-list control group. All women completed individual psychological batteries at baseline and at 1-month follow-up measuring shock anxiety and device acceptance. Pre-post measures of shock anxiety demonstrated a significant time by group interaction effect with the intervention group having a significantly greater decrease (Pillai's trace = 5.58, P = 0.026). A significant interaction effect (Pillai's trace = 5.05, P = 0.046) was found, such that women under the age of 50 experienced greater reduction in shock anxiety than their middle-aged cohorts. Pre-post measures of device acceptance revealed a significant time by group interaction effect with the intervention group having significantly greater increases (Pillai's trace = 5.80, P = 0.023). Structured interventions for female ICD patients involving ICD-specific education, cognitive behavioral therapy strategies, and group social support provide improvements in shock anxiety and device acceptance at 1-month re-assessment. Young women appear to be an at-risk subgroup of this population and may experience more benefit from psychosocial treatment targeting device-specific concerns. ©2010, The Authors.

The aim of the study was to provide further and up to date information on the evaluation of the management of Anorexia and Bulimia nervosa at the Eating Disorders Unit (EDU) of the Ljubljana Psychiatric Clinic, based upon detailed assessment of the eating disorders specific and non specific symptoms of impulsive behaviors, highly correlated with these entities. 34 female patients with anorexia (restrictive or purgative type) and 38 female patients with Bulimia nervosa (purgative or non-purgative type) undergoing hospital treatment at the EDU were evaluated upon admission, as well as upon discharge and three and six months after discharge, using the Eating Disorder Questionnaire. Upon discharge a marked decrease in the overall symptoms was noted. The differences in symptoms incidences between the two groups were significantly specific for the individual form of eating disorder, especially upon admission, and were more pronounced in anorexia group. In later measurements, performed during the period of three and six months after discharge, a mild trend of increase in the disorder specific symptoms was detected in both groups, but was not statistically significant. In addition to binging on food, striking, quarreling and spending sprees are characteristics of patients with eating disorders, which in particular apply to the Bulimia nervosa group. Apart from the disorder specific symptoms, impulsive behavior was also reduced during study period, while the difference in its occurrence between the two groups gradually became non-significant. The management of patients with eating disorders at the EDU was successful in both groups, confirmed by an intense reduction of the disorder specific symptoms, impulsive behavior and increased stability recorded three and six months after discharge. The study strongly suggests that the effect of treatment regime for eating disorders can be predicted by careful assessment of the relevant symptoms and impulsive behavioral patterns.

Candida species are commonly detected isolates from abdominal foci. The question remains as to who would benefit from early empiric treatment in cases of Candida peritonitis. This study collected real-life data on critically ill patients with Candida peritonitis to estimate the relevance of the chosen treatment strategy on the outcome of these patients. One hundred and thirty-seven surgical intensive care unit (ICU) patients with intra-abdominal invasive Candidiasis were included in the study. Fifty-six patients did not get any antifungal agent. Twenty-nine patients were empirically treated, and 52 patients were specifically treated. In the group without, with empiric and with specific antifungal treatment, the 30-day mortality rate was 33.9, 48.3 and 44.2 respectively. Candida albicans was the most frequently found species. Seven patients in the specific treatment group and one patient in the empiric treatment group emerged with candidaemia. Age, leucocyte count, APACHE II Score and acute liver failure were independent predictors of 30-day mortality in patients with Candida peritonitis. Not all patients with Candida peritonitis received antifungal treatment in real clinical practice. Patients with higher morbidity more often got antifungals. Early empirical therapy has not been associated with a better 30-day mortality. © 2017 Blackwell Verlag GmbH.

Bladder management for male patients with spinal cord injury (SCI) challenges the urologist to work around physical and social restrictions set forth by each patient. The objective of this study was to compare the complications associated with urethral catheter (UC) versus suprapubic tube (SPT) in patients with SCI. A retrospective review of records at Long Beach Veterans Hospital was carried out to identify SCI patients managed with SPT or UC. Chart review identified morbidities including urinary tract infection (UTI), bladder stones, renal calculi, urethral complications, scrotal abscesses, epididymitis, gross hematuria and cancer. Serum creatinine measurements were evaluated to determine whether renal function was maintained. In all, 179 patients were identified. There was no significant difference between the two catheter groups in any areas in which they could be compared. There were catheter-specific complications specific to each group that could not be compared. These included erosion in the UC group and urethral leak, leakage from the SPT and SPT revision in the SPT group. Average serum creatinine for the UC and SPT groups was 0.74 and 0.67 mg per 100 ml, respectively. SCI patients with a chronic catheter have similar complication rates of UTIs, recurrent bladder/renal calculi and cancer. Urethral and scrotal complications may be higher with UC; however, morbidity from SPT-specific procedures may offset benefits from SPT. Serum creatinine was maintained in both groups. Overall, bladder management for patients with chronic indwelling catheters should be selected on the basis of long-term comfort for the patient and a physician mind-set that allows flexibility in managing these challenges.

Objective: Graves’ disease and Hashimoto’s thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves’ disease from Hashimoto’s thyroiditis. Methods: This study included 149 patients divided into three groups, patients with Graves’ disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto’s thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. Results: A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves’ was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto’s group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves’ group with 100% and 17.6% specificity and sensitivity, respectively. Conclusion: Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves’ disease or Hashimoto’s thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed. PMID:28451576

To investigate whether concepts important to patients with ankylosing spondylitis (AS) are covered by disease-specific self-report health status instruments. A qualitative focus group study was conducted with AS patients on problems in daily functioning. Group sessions with 4 to 5 patients each were organized up to the point that no new information was brought forward. Group sessions were tape-recorded, transcribed, and divided into meaning units. Concepts contained in the meaning units were extracted. Self-report instruments on health status specific for AS were identified in a literature search. Using the International Classification of Functioning, Disability and Health (ICF) as a common reference, it was determined whether the concepts identified in the focus groups were covered by the instruments. Nineteen patients participated in 4 focus group interviews. In total, 332 unique meaning units were linked to 90 second-level ICF categories, of which 25 referred to body functions, 10 to body structures, 35 to activities and participation and 30 to environmental factors. In addition, several concepts relating to personal factors were identified. Only 47 categories were also covered by one of the self-report instruments in AS. Only a minority of concepts addressed by the AS-specific questionnaires were not revealed as relevant in the interviews. Relevant aspects of the influence of AS are not covered by the classic disease-specific instruments. In particular, the influence of AS on socializing and leisure and the relevance of environmental and personal factors are not adequately assessed by available instruments.

Social media may have the potential to enhance weight management efforts. However, the acceptability of incorporating this entity into pediatrics is unknown. The objective of this project was to explore patients' and parents' perspectives about developing a Facebook group as a component of a pediatric weight management program. Semistructured interviews were performed between September, 2011, and February, 2012, with patients and parents in a multidisciplinary weight management program. Interviews explored participants' perceptions of potential benefits, concerns, and preferences related to a program-specific Facebook group. Transcripts were reviewed and themes identified. The study concluded when thematic saturation was achieved. Participants (n=32) were largely enthusiastic about the idea of a program-specific Facebook group for adolescents. Most preferred a secret group, where only participants would know of the group's existence or group members' identity. No parents expressed concern about security or privacy related to a program-specific Facebook group; one parent expressed concern about undesirable advertisements. Participants endorsed a variety of ideas for inclusion on the page, including weight loss tips, live chats with providers, quizzes, and an incentive system where participants could gain points for making healthy choices. Many parents requested a separate parent-focused page, an idea that was supported by the adolescents. This study suggests that participants perceive potential benefits from incorporating social media interventions into pediatric weight management efforts. Privacy and security issues do not appear to be major parental concerns. Future work should explore the impact of program-specific social media interventions on outcomes for patients in weight management programs.

Dizziness in the elderly is relatively common, but only a few studies are available. The purpose of this study was to analyze the effect of vestibular rehabilitation on dizziness in elderly patients. A total of 240 patients older than 70 years with dizziness who visited the dizziness center of a tertiary care university hospital from January 2000 to January 2004 were studied. The patients' charts were retrospectively reviewed. Thorough otolaryngologic and neurotologic evaluations and vestibular function testing were performed in every case to determine the specific causes of dizziness. General vestibular rehabilitation therapy (VRT) was performed in 103 cases (VRT group) and it was not done on the other 46 cases (non-VRT group). The intensity of dizziness and disequilibrium was evaluated by the verbal analogue scale and Activities-specific Balance Confidence questionnaires that were obtained at 3 weeks and at 3 months after the initiation of general VRT. The average age of the patients was 76.5 +/- 6.2 years. In 153 cases (63%), no specific causes for dizziness were found, which was attributed to presbyastasis. Improvement in dizziness in the VRT group was significantly higher than in the non-VRT group by the verbal analogue scale and Activities-specific Balance Confidence scale obtained at 3 weeks and at 3 months after the initiation of VRT. In the majority of elderly patients with dizziness, the etiology of dizziness is not found and is attributed to presbyastasis. General VRT seems to be an effective treatment for this elderly group.

Functional dyspepsia (FD) is a common disease without an established optimal treatment. To determine (i) the effect of acupuncture in relieving FD symptoms and improving life quality; (ii) the effect difference between acupoint and non-acupoint; and (iii) the effect difference among different acupoints. A total of 712 eligible patients were included and randomly assigned to six groups (Group A: specific acupoints of the stomach meridian; Group B: non-specific acupoints of the stomach meridian; Group C: specific acupoints of alarm and transport points; Group D: specific acupoints of the gallbladder meridian; Group E: sham acupuncture of non-acupoints; and Group F: itopride). A treatment period of 4 weeks (continuous five sessions per week), and a follow-up period of 12 weeks were arranged. The outcomes were the (i) patients' response, (ii) symptoms improvement measured using the Symptom Index of Dyspepsia and (iii) quality-of-life improvement based on Nepean Dyspepsia Index. All groups had an improvement in dyspepsia symptoms and the QoL at the end of treatment, and the improvement was sustained for 4 weeks and 12 weeks. The overall response rate was significantly higher in acupuncture group A (70.69%), and lower in sham acupuncture group (34.75%), compared with itopride and other acupuncture groups. Similarly, the difference in symptoms and QoL improvement was significant between group A and the other acupuncture groups. Acupuncture is effective in the treatment of functional dyspepsia, and is superior to non-acupoint puncture. The benefit of acupuncture relies on acupoint specificity. © 2012 Blackwell Publishing Ltd.

This study assessed the effects of a 6-week telephone based intervention on the pain intensity and physical function of patients with knee osteoarthritis (OA), and compared the results to physiotherapy conducted in the clinic. Fifty randomly selected patients with knee OA were assigned to one of two treatment groups: a clinic group (CG) and a tele-physiotherapy group (TG). The CG received thrice-weekly physiotherapist administered osteoarthritis-specific exercises in the clinic for six weeks. The TG received structured telephone calls thrice-weekly at home, to monitor self-administered osteoarthritis-specific exercises. Participants’ pain intensity and physical function were assessed at baseline, two, four, and six weeks, in the clinic environment. Within group comparison showed significant improvements across baseline, and at weeks two, four, and six for both TG and CG’s pain intensity and physical function. Between-group comparison of CG and TG’s pain intensity and physical function at baseline and weeks two, four, and six showed no significant differences. This study demonstrated that a six-week course of structured telephone calls thrice-weekly to patients at their home, to monitor self-administered osteoarthritis-specific exercises for patients with knee OA (i.e., tele-physiotherapy) achieved comparable results to physiotherapy conducted in the clinic.

Bronchoalveolar lavage (BAL) and protected specimen brushing (PSB) are the most commonly used methods for diagnosing ventilator-associated (VA) pneumonia although they require bronchoscopy. Endotracheal aspiration (EA) is a simple and less costly technique than PSB or BAL. The purpose of our study was to investigate the diagnostic value of EA quantitative cultures and to compare the results obtained using EA with those obtained using PSB and BAL in mechanically ventilated patients with or without pneumonia. We prospectively studied 102 intubated patients divided into three diagnostic categories: Group I (definite pneumonia, n = 26), Group II (uncertain status, n = 48), and Group III (control group, n = 28). All patients received prior antibiotic treatment. EA, PSB, and BAL were obtained sequentially in all patients. When comparing Group I with Group III and using 10(5) cfu/ml as a threshold, we found that EA quantitative cultures represented a relatively sensitive (70%) and relatively specific (72%) method to diagnose VA pneumonia. The specificity of BAL and PSB (87% and 93%, respectively) was better than that of EA. The negative predictive value of EA cultures was higher (72%) when compared with that obtained using PSB (34%) (p < 0.05). EA quantitative cultures correlated with PSB and BAL quantitative cultures in patients with definite pneumonia. Although EA quantitative cultures are less specific than PSB and BAL for diagnosing VA pneumonia, our results suggest that the former approach may be used to treat these patients when bronchoscopic procedures are not available.

The consequences of current intensive chemotherapy for childhood acute lymphoblastic leukemia (ALL) for immune defense are a matter of concern. The purpose of this study was to examine the effect of reduced compared with intensive (conventional) ALL chemotherapy on serum immunoglobulin levels and specific antibody concentrations against vaccine-preventable diseases. Patients treated according to Dutch Childhood Oncology Group ALL 10 protocol were stratified by minimal residual disease to receive reduced (standard risk; SR) or intensive (medium risk; MR) intensification/maintenance treatment. Between November 2004 and July 2009 we compared serum immunoglobulins of 110 patients and specific antibodies against diphtheria toxin, tetanus toxin, and Bordetella pertussis antigens of 41 patients of SR and MR groups during chemotherapy. Immunoglobulin levels showed significantly different patterns between the SR and MR groups. In the MR group IgG, IgA, and IgM levels decreased towards the end of intensive treatment; in the SR group IgG levels increased while IgA and IgM stabilized. In both groups IgM and IgG levels were most affected. Specific antibody levels against vaccine-preventable diseases decreased in both groups, but more profound in MR group. Although reduced chemotherapy is beneficial for immunoglobulin level recovery and might prevent susceptibility for infections, specific antibodies remain decreased.

No instrument exists to assess quality of life (QOL) in adult cochlear implant (CI) users that has been developed and validated using accepted scientific standards. To develop a CI-specific QOL instrument for adults in accordance with the Patient Reported Outcomes Measurement Information System (PROMIS) guidelines. As required in the PROMIS guidelines, patient focus groups participated in creation of the initial item bank. Twenty-three adult CI users were divided into 1 of 3 focus groups stratified by word recognition ability. Three moderator-led focus groups were conducted based on grounded theory on December 3, 2016. Two reviewers independently analyzed focus group recordings and transcripts, with a third reviewer available to resolve discrepancies. All data were reviewed and reported according to the Consolidated Criteria for Reporting Qualitative Research. The setting was a tertiary referral center. Coded focus group data. The 23 focus group participants (10 [43%] female; mean [range] age, 68.1 [46.2-84.2] years) represented a wide range of income levels, education levels, listening modalities, CI device manufacturers, duration of CI use, and age at implantation. Data saturation was determined to be reached before the conclusion of each of the focus groups. After analysis of the transcripts, the central themes identified were communication, emotion, environmental sounds, independence and work function, listening effort, social isolation and ability to socialize, and sound clarity. Cognitive interviews were carried out on 20 adult CI patients who did not participate in the focus groups to ensure item clarity. Based on these results, the initial QOL item bank and prototype were developed. Patient focus groups drawn from the target population are the preferred method of identifying content areas and domains for developing the item bank for a CI-specific QOL instrument. Compared with previously used methods, the use of patient-centered item development for a CI-specific QOL instrument will more accurately reflect patient experience and increase our understanding of how CI use affects QOL.

Task-specific focal dystonia is a movement disorder that is characterized by the loss of voluntary motor control in extensively trained movements. Musician's dystonia is a type of task-specific dystonia that is elicited in professional musicians during instrumental playing. The disorder has been associated with deficits in timing. In order to test the hypothesis that basic timing abilities are affected by musician's dystonia, we investigated a group of patients (N = 15) and a matched control group (N = 15) on a battery of sensory and sensorimotor synchronization tasks. Results did not show any deficits in auditory-motor processing for patients relative to controls. Both groups benefited from a pacing sequence that adapted to their timing (in a sensorimotor synchronization task at a stable tempo). In a purely perceptual task, both groups were able to detect a misaligned metronome when it was late rather than early relative to a musical beat. Overall, the results suggest that basic timing abilities stay intact in patients with musician's dystonia. This supports the idea that musician's dystonia is a highly task-specific movement disorder in which patients are mostly impaired in tasks closely related to the demands of actually playing their instrument.

Marital status correlates with health. Our goal was to examine the impact of marital status on the survival outcomes of patients with colorectal neuroendocrine neoplasms (NENs). The Surveillance, Epidemiology and End Results program was used to identify 1,289 eligible patients diagnosed between 2004 and 2010 with colorectal NENs. Statistical analyses were performed using Chi-square, Kaplan-Meier, and Cox regression proportional hazards methods. Patients in the widowed group had the highest proportion of larger tumor (>2cm), and higher ratio of poor grade (Grade III and IV) and more tumors at advanced stage (P<0.05). The 5-year cause specific survival (CSS) was 76% in the married group, 51% in the widowed group, 73% in the single group, and 72% in the divorced/separated group, which manifest statistically significant difference in the univariate log-rank test and Cox regression model (P<0.05). Furthermore, marital status was an independent prognostic factor only in Distant stage (P<0.001). In conclusion, patients in widowed group were at greater risk of cancer specific mortality from colorectal NENs and social support may lead to improved outcomes for patients with NENs.

To investigate the influence of metabolic syndrome on prostate-specific antigen levels by considering prostate volume and plasma volume. We retrospectively analyzed 4111 men who underwent routine check-ups including prostate-specific antigen and transrectal ultrasonography. The definition of metabolic syndrome was based on the modified Adult Treatment Panel III criteria. Prostate-specific antigen mass density (prostate-specific antigen × plasma volume / prostate volume) was calculated for adjusting plasma volume and prostate volume. We compared prostate-specific antigen and prostate-specific antigen mass density levels of participants with metabolic syndrome (metabolic syndrome group, n = 1242) and without metabolic syndrome (non-prostate-specific antigen metabolic syndrome group, n = 2869). To evaluate the impact of metabolic syndrome on prostate-specific antigen, linear regression analysis for the natural logarithm of prostate-specific antigen was used. Patients in the metabolic syndrome group had significantly older age (P < 0.001), larger prostate volume (P < 0.001), higher plasma volume (P < 0.001) and lower mean serum prostate-specific antigen (non-metabolic syndrome group vs metabolic syndrome group; 1.22 ± 0.91 vs 1.15 ± 0.76 ng/mL, P = 0.006). Prostate-specific antigen mass density in the metabolic syndrome group was still significantly lower than that in the metabolic syndrome group (0.124 ± 0.084 vs 0.115 ± 0.071 μg/mL, P = 0.001). After adjusting for age, prostate volume and plasma volume using linear regression model, the presence of metabolic syndrome was a significant independent factor for lower prostate-specific antigen (prostate-specific antigen decrease by 4.1%, P = 0.046). Prostate-specific antigen levels in patients with metabolic syndrome seem to be lower, and this finding might be affected by the prostate volume. © 2016 The Japanese Urological Association.

Background: Acupuncture is commonly used to treat migraine. We assessed the efficacy of acupuncture at migraine-specific acupuncture points compared with other acupuncture points and sham acupuncture. Methods: We performed a multicentre, single-blind randomized controlled trial. In total, 480 patients with migraine were randomly assigned to one of four groups (Shaoyang-specific acupuncture, Shaoyang-nonspecific acupuncture, Yangming-specific acupuncture or sham acupuncture [control]). All groups received 20 treatments, which included electrical stimulation, over a period of four weeks. The primary outcome was the number of days with a migraine experienced during weeks 5–8 after randomization. Our secondary outcomes included the frequency of migraine attack, migraine intensity and migraine-specific quality of life. Results: Compared with patients in the control group, patients in the acupuncture groups reported fewer days with a migraine during weeks 5–8, however the differences between treatments were not significant (p > 0.05). There was a significant reduction in the number of days with a migraine during weeks 13–16 in all acupuncture groups compared with control (Shaoyang-specific acupuncture v. control: difference –1.06 [95% confidence interval (CI) –1.77 to –0.5], p = 0.003; Shaoyang-nonspecific acupuncture v. control: difference –1.22 [95% CI –1.92 to –0.52], p < 0.001; Yangming-specific acupuncture v. control: difference –0.91 [95% CI –1.61 to –0.21], p = 0.011). We found that there was a significant, but not clinically relevant, benefit for almost all secondary outcomes in the three acupuncture groups compared with the control group. We found no relevant differences between the three acupuncture groups. Interpretation: Acupuncture tested appeared to have a clinically minor effect on migraine prophylaxis compared with sham acupuncture. Trial Registration: Clinicaltrials.gov NCT00599586 PMID:22231691

Sport is increasingly recommended for haemophilic patients due to physical and psychological benefits. 'WATERCISE' is a specific aqua-training programme for haemophiliacs in which endurance, strength, coordination and mobility are trained. In the WAT-QoL study benefits and risks of regular WATERCISE training sessions were investigated in terms of health-related quality of life (HRQoL), physical functioning (PF), orthopaedic joint status (OJS), bleeding frequency and factor consumption. Patients in the WATERCISE group attended an aqua-training programme once a week for 1 h over 12 months, patients in the control group did not. Patients were matched for clinical and demographic data. Information on clinical data, orthopaedic status, PF (HEP-Test-Q) and HRQoL were collected in both groups at baseline and at follow-up (6 and 12 months). Twenty-eight adult severely affected haemophilic patients (WATERCISE group: 10 haemophilia A (HA), 3 haemophilia B (HB) patients; control group: 12 HA and 3 HB patients) were enrolled (aged 40.68 ± 12.7 years). Baseline data (body mass indices, OJS, sportive activities, HRQoL and PF) were well distributed between groups. After 12 months the WATERCISE group reported a significantly better PF (M(W) = 65.22, SD = 11.3; M(C) = 52.5, SD = 15.0), especially for endurance (P < 0.004). Although always differently reported by the patients within the WATERCISE group, HRQoL did not prove to be significantly different between groups. WATERCISE seems to have a positive effect on the PF of patients suffering from haemophilia. These study findings need to be further investigated in a larger study group. © 2012 Blackwell Publishing Ltd.

Procedure volume is an important determinant of total knee arthroplasty (TKA) outcomes. We aimed to determine whether computer navigation or patient-specific instrumentation (PSI) would improve postoperative alignment in a low-volume setting. PSI for TKA achieves better limb and implant alignment compared to conventional TKA and to computer navigated TKA. This is a retrospective cohort study of 385 primary TKAs (Women=59%. Mean age=67years. Mean BMI=30.1kg/m 2 ), which were performed using conventional instrumentation (n=117; 30%), computer navigation (n=209; 54%), or patient-specific instrumentation (n=59; 15%) in a low-volume center (<50 TKAs/year). The risk of postoperative leg and implant mechanical alignment outliers in the coronal plane (>3° from neutral), average alignment and operation time were assessed. The risk of postoperative mechanical alignment outliers (>3°) was reduced by 89% in the navigated group (4% outliers) compared to the conventional group (35%) (RR=0.11; p<0.0001). No significant improvement was observed in the PSI group (27%) (RR=0.91; p=0.772). The risk of postoperative femoral component coronal alignment outliers was reduced by 63% in the navigated group (11%) compared to the conventional group (31%) (RR=0.37; p=0.018). No significant reduction in outliers was observed in the PSI group (32%) (RR=1.08; p=0.816). There was a reduction in the risk of tibial component coronal malalignment of 66% in the navigated group (5%) compared to the conventional group (13%) (RR=0.33; p=0.070). There was a two-fold increase in the risk of tibial component alignment outliers in the PSI group (29%) (RR=1.94; p=0.110). Computer navigation improved postoperative alignment in TKA. No evidence of improved alignment was seen with patient-specific instrumentation. The routine use of patient-specific instrumentation in low-volume centers is not supported by the currently available data. Retrospective cohort study. Level IV. Copyright © 2018 Elsevier Masson SAS.

Comparing metagenomic samples is crucial for understanding microbial communities. For different groups of microbial communities, such as human gut metagenomic samples from patients with a certain disease and healthy controls, identifying group-specific sequences offers essential information for potential biomarker discovery. A sequence that is present, or rich, in one group, but absent, or scarce, in another group is considered “group-specific” in our study. Our main purpose is to discover group-specific sequence regions between control and case groups as disease-associated markers. We developed a long k-mer (k ≥ 30 bps)-based computational pipeline to detect group-specific sequences at strain resolution free from reference sequences, sequence alignments, and metagenome-wide de novo assembly. We called our method MetaGO: Group-specific oligonucleotide analysis for metagenomic samples. An open-source pipeline on Apache Spark was developed with parallel computing. We applied MetaGO to one simulated and three real metagenomic datasets to evaluate the discriminative capability of identified group-specific markers. In the simulated dataset, 99.11% of group-specific logical 40-mers covered 98.89% disease-specific regions from the disease-associated strain. In addition, 97.90% of group-specific numerical 40-mers covered 99.61 and 96.39% of differentially abundant genome and regions between two groups, respectively. For a large-scale metagenomic liver cirrhosis (LC)-associated dataset, we identified 37,647 group-specific 40-mer features. Any one of the features can predict disease status of the training samples with the average of sensitivity and specificity higher than 0.8. The random forests classification using the top 10 group-specific features yielded a higher AUC (from ∼0.8 to ∼0.9) than that of previous studies. All group-specific 40-mers were present in LC patients, but not healthy controls. All the assembled 11 LC-specific sequences can be mapped to two strains of Veillonella parvula: UTDB1-3 and DSM2008. The experiments on the other two real datasets related to Inflammatory Bowel Disease and Type 2 Diabetes in Women consistently demonstrated that MetaGO achieved better prediction accuracy with fewer features compared to previous studies. The experiments showed that MetaGO is a powerful tool for identifying group-specific k-mers, which would be clinically applicable for disease prediction.

Background This study is conducted to compare the metacognition treatment and the mindfulness-based stress reduction treatment on life quality of women with breast cancer. Methods In a quasi-experimental design, with pre-test, post-test and control group, 36 patients with diagnosis of breast cancer, among patients who referred to the Division of Oncology and Radiotherapy of Imam Hossein hospital in Tehran, were selected in accessible way and were assigned randomly to three experimental groups, the first group receiving meta-cognition treatment (n=12), the second one receiving mindfulness-based stress reduction program (n=12), and the other was the control group. Participants completed global life quality in cancer patient's questionnaire and specific quality of life in breast cancer patient's questionnaire in three stages: baseline, after intervention and two-month follow-up. Data were analyzed using the multivariate repeated measurement model. Results Findings showed both treatments were effective in improving global and specific quality of life in patients with breast cancer. The mindfulness -based stress reduction treatment excelled in functions and roles, fatigue, pain, future perspective and treatment side effects symptoms at the end of the treatment and follow-up in comparison to the metacognition treatment. Conclusion Results of this research showed the mindfulness-based stress reduction treatment can be effective in improving global and specific life quality of women with breast cancer and is a selective method for improving quality of life in patients.

Pulmonary hypertension (PH) complicating chronic obstructive pulmonary disease (COPD-PH) and interstitial lung disease (ILD-PH) (World Health Organization [WHO] Group III PH) increases medical costs and reduces survival. Despite limited data, many clinicians are using pulmonary arterial hypertension (PAH)-specific therapy to treat WHO Group III PH patients. To further investigate the utility of PAH-specific therapy in WHO Group III PH, we performed a systematic review and meta-analysis. Relevant studies from January 2000 through May 2016 were identified in the MEDLINE, EMBASE, and COCHRANE electronic databases and www.clinicaltrials.gov. Change in six-minute walk distance (6MWD) was estimated using random effects meta-analysis techniques. Five randomized controlled trials (RCTs) in COPD-PH (128 placebo or standard treatment and 129 PAH-medication treated patients), two RCTs in ILD-PH (23 placebo and 46 treated patients), and four single-arm clinical trials (50 patients) in ILD-PH were identified. Treatment in both COPD-PH and ILD-PH did not worsen hypoxemia. Symptomatic burden was not consistently reduced but there were trends for reduced pulmonary artery pressures and pulmonary vascular resistance with PAH-specific therapy. As compared to placebo, 6MWD was not significantly improved with PAH-specific therapy in the five COPD-PH RCTs (42.7 m; 95% confidence interval [CI], -1.0 - 86.3). In the four single-arm studies in ILD-PH patients, there was a significant improvement in 6MWD after PAH-specific treatment (46.2 m; 95% CI, 27.9-64.4), but in the two ILD-PH RCTs there was not an improvement (21.6 m; 95% CI, -17.8 - 61.0) in exercise capacity when compared to placebo. Due to the small numbers of patients evaluated and inconsistent beneficial effects, the utility of PAH-specific therapy in WHO Group III PH remains unproven. A future clinical trial that is appropriately powered is needed to definitively determine the efficacy of this widely implemented treatment approach.

We aim to find the risk factors that influence the formation of bladder calculi in patients with benign prostate hyperplasia (BPH) and to reduce the surgical intervention related to bladder calculi.Between January 2015 and October 2016, 332 patients with BPH underwent surgical therapy were retrospectively evaluated. Patients with BPH were categorized into 2 groups: 94 patients with bladder calculi in group 1 and 238 patients without bladder calculi in group 2. Medical history, age, body mass index (BMI), total prostate specific antigen, total prostate volume (TPV), International Prostate Symptom Score (IPSS), intravesical prostatic protrusion (IPP), urodynamic parameters, and urine culture were compared between groups.There was no significant difference in the age, BMI, peak flow rate, and total IPSS between groups. TPV, total prostate specific antigen, and duration of BPH were significantly lower in group 1 than those in group 2. In addition, IPP was significantly higher in group 1 than group 2 (P < .001). Besides, after exclusion of patients with urinary retention and indwelling catheter, group 1 associated with a significantly higher preoperative positive rate of urine culture than that of group 2 (P = .046). Multivariate analysis indicated that IPP was a significant independent risk factor for the presence of bladder calculi.The incidence of bladder calculi in patients with BPH was proved to be closely associated with preoperative positive urine culture and longer IPP in our study. Furthermore, the IPP was presented to be an independent risk factor for the formation of bladder calculi. And early antibacterial therapy of urinary tract infection (UTI) may help to prevent the presence of bladder calculi in patients with BPH.

This article presents an historical overview of the changing meaning of the patient-consumer, and specifically the role played by patient groups in constructing the patient as consumer. It is argued that patient groups were central to the formation of the patient-consumer, but as health consumerism was taken on by the state, they lost control of this figure. Competing understandings of what it meant to be a patient-consumer developed, a shift that raises further questions about the unity of claims made in the name of the patient-consumer. PMID:20798768

We asked whether there would be any difference between primary and revision modern cemented fixed hinge megaprosthesis of the distal femur in function and activity-related outcomes following treatment of a bone tumor. An identical custom-made fixed hinge cemented megaprosthesis with a hydroxyapatite collar was used in all cases. The main outcomes were joint-specific function, disease-specific activity, and health-related quality of life. Implant survival was also evaluated. Patients in the revision group performed slightly better than patients in the primary group on disease-specific (Toronto Extremity Salvage Score, p  = 0.033; Musculoskeletal Tumor Society, p  = 0.072) and health-related outcomes (Short Form 36 [SF-36] physical component, p  = 0.085; SF-36 mental component, p  = 0.069) but not on joint-specific outcomes (Knee Society Score, p  = 0.94). The cumulative probabilities of revision for any reason were 14.5% (7-25%) at 5 years with no statistically significant difference between primary and revision procedures ( p  = 0.77). In conclusion, patients undergoing a revision have similar joint-specific functional outcome but improved disease-specific and health-related outcomes. Implant survival are similar between groups.

Some patients with interstitial lung disease (ILD) related to connective tissue disease (CTD) have a delayed diagnosis of the underlying CTD when the ILD is categorized as idiopathic. In this study, we evaluated the frequency of myositis autoantibodies in patients diagnosed with idiopathic ILD and investigated the clinical significance stemming from the presence of the antibodies. A total 32 patients diagnosed with idiopathic ILD were enrolled in this study. We analyzed a panel of 11 myositis autoantibody specificities in the patients using a line blot immunoassay. Then, we divided them into myositis autoantibody-positive and -negative groups and compared the clinical features and laboratory data between the two groups. Of the 32 idiopathic ILD patients, 12 patients had myositis autoantibodies encompassing 9 specificities, except for anti-Mi-2 and anti-PM-Scl 100 (12/32, 38%). Anti-synthetase autoantibodies including Jo-1, EJ, OJ, PL-7, and PL-12 were present in 7 patients (7/32, 22%). The group with myositis autoantibodies presented more frequently with the symptom of mechanic's hand and showed abnormal pulmonary function test results with low forced vital capacity, diffusing capacity for carbon monoxide, total lung capacity, and high lactate dehydrogenase values in blood when compared with the group without myositis antibodies. We strongly suggest that patients undergo an evaluation of myositis autoantibodies, if they are diagnosed with idiopathic ILD in the presence of clinical characteristics including mechanic's hand, arthralgia, and autoantibodies which are insufficient to make a diagnosis of a specific CTD category.

This study aimed to investigate oxidative stress in etiopathogenesis by analyzing serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), arylesterase, IgE, and C-reactive protein (CRP) in bladder pain syndrome/interstitial cystitis (BPS/IC). The study included 16 female patients diagnosed with BPS/IC and 25 healthy female subjects forming the control group. A bladder biopsy was performed on all patients in the BPS/IC group by carrying out cystoscopy with hydrodistention under general anesthesia. The results of serum TAC, TOS, IMA, AOPP, PON, arylesterase, IgE, and CRP of the subjects in both groups were compared. The mean age of the 16 female patients in the BPS/IC group was 43.6 ± 14.5 years, and the mean age of the 25 healthy subjects in the control group was 42.0 ± 10.3 years. According to the criteria of International Society for the Study of Interstitial Cystitis (ESSIC), eight patients were classified as Type 2A, three patients as Type 2B, four patients as Type 2C, and one patient as Type 3C. In the BPS/IC group, while TAC was found significantly lower than in the control group, IMA, IgE, and CRP were found significantly higher (P < 0.05). When binary logistic regression analysis was performed, the created model was determined to have 81.3 % sensitivity and 80 % specifity. In the etiology of BPS/IC, mechanism of oxidative damage comes into prominence. In the diagnosis of BPS/IC, IgE, CRP, and TAC are not specific markers when used separately; however, a higher specifity and sensitivity could be reached when used jointly in the suspected patients.

Manual therapy according to the School of Manual Therapy Utrecht (MTU) is a specific type of passive manual joint mobilization. MTU has not yet been systematically compared to other manual therapies and physical therapy. In this study the effectiveness of MTU is compared to physical therapy, particularly active exercise therapy (PT) in patients with non-specific neck pain. Patients neck pain, aged between 18-70 years, were included in a pragmatic randomized controlled trial with a one-year follow-up. Primary outcome measures were global perceived effect and functioning (Neck Disability Index), the secondary outcome was pain intensity (Numeric Rating Scale for Pain). Outcomes were measured at 3, 7, 13, 26 and 52 weeks. Multilevel analyses (intention-to-treat) were the primary analyses for overall between-group differences. Additional to the primary and secondary outcomes the number of treatment sessions of the MTU group and PT group was analyzed. Data were collected from September 2008 to February 2011. A total of 181 patients were included. Multilevel analyses showed no statistically significant overall differences at one year between the MTU and PT groups on any of the primary and secondary outcomes. The MTU group showed significantly lower treatment sessions compared to the PT group (respectively 3.1 vs. 5.9 after 7 weeks; 6.1 vs. 10.0 after 52 weeks). Patients with neck pain improved in both groups without statistical significantly or clinically relevant differences between the MTU and PT groups during one-year follow-up.

Extranodal natural killer (NK)/T cell lymphoma, nasal type, is a recently recognized distinct entity and the most common type of non-B cell extranodal lymphoma in Asia. This retrospective analysis studied the potential survival benefits of hematopoeitic stem cell transplantation (HSCT) compared with a historical control group. A total of 47 patients from 3 previously published series of HSCT were matched according to NK/T cell lymphoma International Prognostic Index (NKIPI) risk groups and disease status at transplantation with 107 patients from a historical control group for analysis. After a median follow-up of 116.5 months, the median survival time was not determined for the HSCT group, but it was 43.5 months for the control group (95% confidence interval [CI] = 6.7 to 80.3 months; P = .127, log-rank test). In patients who were in complete remission (CR) at the time of HSCT or at surveillance after remission, disease-specific survival rates were significantly higher in the HSCT group compared with the control group (disease-specific 5-year survival rate, 87.3% for HSCT vs 67.8% for non-HSCT; P = .027). In contrast, in subgroup analysis on non-CR patients at the time of HSCT or non-HSCT treatment, disease-specific survival rates were not significantly prolonged in the HSCT group compared with the control group (1-year survival rate, 66.7% for HSCT vs 28.6% for non-HSCT; P = .141). The impact of HSCT on the survival of all patients was significantly retained at the multivariate level with a 2.1-fold (95% CI =1.2- to 3.7-fold) reduced risk of death (P = .006). HSCT seems to confer a survival benefit in patients who attained CR on postremission consolidation therapy. These findings suggest that, in particular, patients in CR with high NKIPI risk scores at diagnosis should receive full consideration for HSCT.

To report the results of a trial comparing the efficacy of triptorelin and surgical castration in the treatment of locally advanced or metastatic prostate cancer. 80 patients with previously untreated locally advanced or metastatic prostate cancer prostate cancer were included in a one-year multicentre, randomized, prospective, open-label therapeutic trial. Patients either received a monthly injection of triptorelin (group 1; n = 40), or were treated by pulpectomy (group 2; n = 40). Patients were reviewed every 3 months, then every 6 months. The mean age of the patients was 71.22 +/- 8.25 years. At 1 month, 38 patients were castrated (plasma testosterone < 0.5 mg/ml) in the pulpectomy group versus 35 in the triptorelin group. The mean follow-up was 38.8 +/- 26 months in the triptorelin group and 36.3 +/- 25 months in the pulpectomy group. On multivariate analysis, age, impaired performance status and PAP level (> 3.2 ng/ml) were predictive factors of a poor outcome. The median survival was 37.5 +/- 9 months in the triptorelin group and 33 +/- 3 months in the pulpectomy group. At 3 years, no significant difference in specific survival was observed between the 2 groups. At 8 years of follow-up, 63 patients had died. This study demonstrates an equivalent specific survival between patients treated by triptorelin or surgical castration. Castration is rapidly obtained with triptorelin (< 2 months) and is maintained over time throughout the duration of treatment.

Whether subgroups of functional dyspepsia (FD) should be treated with different approaches is controversially discussed in research. As our previous study has demonstrated the effect of acupuncture in FD treatment, we now further analyze the therapeutic effect of acupuncture in the treatment of postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). A retrospective analysis was conducted in 465 eligible PDS patients and 241 EPS patients. 4 acupuncture groups (group A: specific acupoints along the stomach meridian; group B: non-specific acupoints along the stomach meridian; group C: alarm and transport acupoints; group D: specific acupoints along the gallbladder meridian) were compared with a non-acupoint sham acupuncture group and an itopride group. The patients were treated in 5 consecutive sessions per week for 4 weeks and were followed-up for 12 weeks afterwards. Primary outcome of the study was defined as response rate and symptom improvement as measured by the Symptom Index of Dyspepsia, while secondary outcome was designated as improvement in quality of life (QoL) as determined by the Nepean Dyspepsia Index. Symptoms of dyspepsia and QoL were improved from baseline in all groups. In EPS patients, no statistically significant differences could be observed in response rate (p = 0.239) and symptoms improvement (p = 0.344 for epigastric pain; p = 0.465 for epigastric burning). In contrast, PDS patients of the acupuncture group A showed higher response rate (53.2% vs. 19.7%, p<0.001; 53.2% vs. 35.1%, p = 0.025) and score change in postprandial fullness (1.01 vs. 0.27, p<0.001; 1.01 vs. 0.57, p<0.001), early satiation (0.81 vs. 0.21, p<0.001; 0.81 vs. 0.39, p=0.001), and QoL (14.5 vs. 4.33, p<0.001; 14.5 vs. 8.5, p<0.001) compared to the sham acupuncture and itopride group. FD patients with PDS responded better to the acupuncture therapies, especially at the specific acupoints along the stomach meridian. The positive therapeutic effect of acupuncture on PDS was correlated with the improvement in postprandial fullness. ClinicalTrial.gov NCT00599677. © 2015 S. Karger GmbH, Freiburg.

To investigate the association between prostate specific antigen (PSA) bounce and disease outcome after prostate brachytherapy. We analyzed 975 patients treated with (125)I implantation monotherapy between 1992 and 2006. All patients had tumor Stage ≤ 2c, Gleason score ≤ 7 prostate cancer, a minimum follow-up of 2 years with at least four PSA measurements, and no biochemical failure in the first 2 years. Median follow-up was 6 years. Bounce was defined as a PSA elevation of +0.2 ng/mL with subsequent decrease to previous nadir. We used the Phoenix +2 ng/mL definition for biochemical failure. Additional endpoints were disease-specific and overall survival. Multivariate Cox regression analysis was performed to adjust for potential confounding factors. Bounce occurred in 32% of patients, with a median time to bounce of 1.6 years. More than 90% of bounces took place in the first 3 years after treatment and had disappeared within 2 years of onset. Ten-year freedom from biochemical failure, disease-specific survival, and overall survival rates were, respectively, 90%, 99%, and 88% for the bounce group and 70%, 93%, and 82% for the no-bounce group. Only 1 patient (0.3%) died of prostate cancer in the bounce group, compared with 40 patients (6.1%) in the no-bounce group. Adjusted for confounding, a 70% biochemical failure risk reduction was observed for patients experiencing a bounce (hazard ratio 0.31; 95% confidence interval 0.20-0.48). A PSA bounce after prostate brachytherapy is strongly related to better outcome in terms of biochemical failure, disease-specific survival, and overall survival. Copyright © 2012 Elsevier Inc.

Abstract Background Social media may have the potential to enhance weight management efforts. However, the acceptability of incorporating this entity into pediatrics is unknown. The objective of this project was to explore patients' and parents' perspectives about developing a Facebook group as a component of a pediatric weight management program. Methods Semistructured interviews were performed between September, 2011, and February, 2012, with patients and parents in a multidisciplinary weight management program. Interviews explored participants' perceptions of potential benefits, concerns, and preferences related to a program-specific Facebook group. Transcripts were reviewed and themes identified. The study concluded when thematic saturation was achieved. Results Participants (n=32) were largely enthusiastic about the idea of a program-specific Facebook group for adolescents. Most preferred a secret group, where only participants would know of the group's existence or group members' identity. No parents expressed concern about security or privacy related to a program-specific Facebook group; one parent expressed concern about undesirable advertisements. Participants endorsed a variety of ideas for inclusion on the page, including weight loss tips, live chats with providers, quizzes, and an incentive system where participants could gain points for making healthy choices. Many parents requested a separate parent-focused page, an idea that was supported by the adolescents. Conclusions This study suggests that participants perceive potential benefits from incorporating social media interventions into pediatric weight management efforts. Privacy and security issues do not appear to be major parental concerns. Future work should explore the impact of program-specific social media interventions on outcomes for patients in weight management programs. PMID:23869854

Objectives: To determine whether the mean platelet volume (MPV) and MPV/platelet (PLT) values can be used in the study of sepsis and systemic inflammatory response syndrome (SIRS). Methods: In this retrospective case-controlled study, 69 sepsis, 69 SIRS patients, and 72 control group who were treated in the years 2012-2013 were reviewed, and both the MPV and MPV/PLT rates were evaluated in all groups at Kahramanmaras Sutcu Imam University Intensive Care Unit, Kahramanmaras, Turkey. Results: Statistically significant difference was found between sepsis, SIRS, and control groups when comparing the MPV and MPV/PLT ratio (p<0.05), and no significant difference was found between sepsis and SIRS groups in terms of MPV and MPV/PLT ratio (p>0.05). Mean platelet volume values for sepsis and control groups was 10.07/8.731 femtoliter (fL) (p=0.000), and 9.45/8.731 fL (p=0.000) for SIRS and control groups. In the group of sepsis patients, the MPV was found to be at cut-off 8.915, sensitivity 71%, and specificity 63.9%. In the group of patients with SIRS, MPV was found to be at cut-off 8.85, sensitivity 69.6%, and specificity 62.5%. For the MPV/PLT values, the specificity and sensitivity were found to be insignificant. Conclusion: This study shows that although there was no significant reduction in the PLT values between the sepsis and SIRS patients, the MPV and MPV/PLT ratio values were found to have significant differences. However, the specificity and sensitivity of the values were not reliable standard to be used as a test. PMID:26446329

Active surveillance is now the treatment of choice in men with low risk prostate cancer. Although there is no consensus on which patients are eligible for active surveillance, prostate specific antigen above 10 ng/ml is generally excluded. In an attempt to determine the validity of using a prostate specific antigen cutoff of 10 ng/ml to counsel men considering active surveillance we analyzed a multi-institution database to determine the pathological outcome in men with prostate specific antigen greater than 10 ng/ml but histologically favorable risk prostate cancer. We queried a prospectively maintained database of men with histologically favorable risk prostate cancer who underwent radical prostatectomy between 2003 and 2015. The cohort was categorized into 3 groups based on prostate specific antigen level, including low-less than 10 ng/ml, intermediate-10 or greater to less than 20 and high-20 or greater. Associations of prostate specific antigen group with adverse pathological and oncologic outcomes were analyzed. Of 2,125 patients 1,327 were categorized with histologically favorable risk disease. However on multivariate analyses the rates of up staging and upgrading were similar between the intermediate and low prostate specific antigen groups. In contrast compared to the intermediate prostate specific antigen group the high group had higher incidences of up staging (p = 0.02) and upgrading to 4 + 3 or greater disease (p = 0.046). Biochemical recurrence-free survival rates revealed no pairwise intergroup differences except between the low and high groups. Patients with preoperatively elevated prostate specific antigen between 10 and less than 20 ng/ml who otherwise had histologically favorable risk prostate cancer were not at higher risk for adverse pathological outcomes than men with prostate specific antigen less than 10 ng/ml.

Background Transverse sinus stenosis (TSS) is common among patients with cerebral venous sinus thrombosis. No previous studies have reported on double-track sign detected on axial Gd-enhanced T1WI in TSS. This study aimed to determine the sensitivity and specificity of the double-track sign in the detection of TSS. Methods We retrospectively reviewed medical records of 383 patients with transverse sinus thrombosis (TST) and 30 patients with normal transverse sinus from 5 participating hospitals in china from January 2008 to June 2014. 167 feasible transverse sinuses included in this study were categorized into TSS (n = 76), transverse sinus occlusion (TSO) (n = 52) and transverse sinus normal (TSN) groups (n = 39) according to imaging diagnosis on digital subtraction angiography (DSA) or magnetic resonance venography (MRV). Double-track sign on axial Gd-enhanced T1WI was compared among the three groups. Sensitivity and specificity of double-track sign in detection of TSS were calculated, with final imaging diagnosis of TSS on DSA or MRV as the reference standard. Results Of 383 patients with TST recruited over a 6.5-year period, 128 patients were enrolled in the study, 255 patients were excluded because of insufficient clinical data, imaging finding and delay time, and 30 matched patients with normal transverse sinus were enrolled in the control group. Therefore, double-track sign assessment was conducted in 167 available transverse sinuses of 158 patients. Of the 76 sinuses in TSS group, 51 had double-track sign. Of the other 91 sinuses in TSO and TSN groups, 3 had a false-positive double-track sign. Thus, double-track sign on axial Gd-enhanced T1WI was 67.1% (95% CI 55.3–77.2) sensitive and 96.7% (95% CI 89.9–99.1) specific for detection of TSS. Conclusions The double-track sign on axial Gd-enhanced T1WI is highly specific and moderate sensitive for detection of TSS. Nevertheless, it could be a direct sign and might provide an early clue for TSS. PMID:26291452

Preoperative intraaortic balloon pump (IABP) counterpulsation has better outcomes compared with perioperative or postoperative insertion in critical patients, and off-pump surgical procedures have been advocated to reduce mortality in high-risk patients. However, some surgeons are reluctant to perform beating heart operations in specific patient subgroups, including those with unstable angina or patients with low ejection fraction, because of their possible perioperative hemodynamic instability. We evaluated combined beating heart procedures and preoperative IABP in selected high-risk patients and compared our results with the predictive European System for Cardiac Operative Risk Evaluation (EuroSCORE) model. Fifty-five high-risk patients with a mean logistic EuroSCORE of 24 were prospectively enrolled and then divided into emergency (group 1, n = 25) and nonemergency (group 2, n = 30) groups. IABP was inserted immediately before operation in group 1 and the day before the procedure in group 2. Compared with the EuroSCORE predictive model, a dramatic decrease in mortality occurred in both groups. Group I predicted mortality was 36.8%, and observed was 20%; and group 2 predicted mortality was 15.2% and observed was 0%. No specific complications from the use of IABP were encountered. During mid-term (2 years) follow-up, no patient died from a cardiac cause or required percutaneous coronary intervention or subsequent reoperation due to incomplete revascularization. The combined use of preoperative intraaortic counterpulsation and beating heart intervention allows complete revascularization in high-risk patients with a important reduction in operative mortality and excellent mid-term results.

According to cognitive-behavioral models of hypochondriasis (HYP), biased attentional and memory processes related to health threat stimuli are crucial for the development and maintenance of severe health anxiety. Little is known about the specificity, temporal stability, and modifiability of these biases via psychotherapy. In an emotional Stroop and subsequent recognition task, the authors compared attention and memory processes for health-related words (illnesses, bodily complaints, and panic-related words) in patients with HYP (n = 32), other somatoform disorders (SFD; n = 27), and panic disorder (PD; n = 25). A control group consisted of 31 healthy participants (CG). All patients were reexamined after 4 months of cognitive-behavioral therapy (CBT). Patients with HYP showed a significant attentional bias toward all 3 target word categories. Evidence for a specific bias was found only for the PD group. General recognition performance for health threat and neutral words was best in the HYP group. After therapy, attentional bias had clearly decreased in the HYP and SFD patients. Patients with HYP can be characterized by attentional bias and more elaborate verbal processing. These irregularities tend to disappear after psychotherapy.

For three years 128 pollinosis patients received specific immunotherapy with cereals, weed and tree pollen allergens manufactured by the Scientific and Industrial Amalgamation "Allergen" (Stavropol). For comparison, a group of 42 patients was treated with the corresponding allergens according to the commonly used treatment scheme. Patients who had earlier undergone treatment with water-saline extracts of allergens, that proved to be ineffective, formed a special group. In sensitive patients reaction to the skin test with allergoids was by half less pronounced than reaction to the skin test with allergens. In allergometric titration on the nasal mucosa, reaction to the introduction of allergoids could be registered when they were used at a 10- to 100-fold higher concentration than allergens. The course of specific immunotherapy with allergoids was found to lead to a decrease in the level of allergen-specific IgE antibodies (p > 0.05) and total IgE (p < 0.01). An increase in the level of IgG antibodies was noted (p < 0.01). Specific immunotherapy with allergoids was more effective than that with water-saline extracts of allergens. The use of allergoids made it possible to prescribe specific immunotherapy to a wider circle of patients.

Alloimmunization to red blood cell (RBC) antigens after transfusion is well described in patients with sickle cell disease (SCD). We recently demonstrated that leukocyte-reduced RBC transfusions appeared to induce human leukocyte antigen (HLA) antibodies in some children with SCD; now, we hypothesize that residual platelets contained in transfused RBC products may lead to platelet glycoprotein antibody formation. A cross-sectional study was conducted among never pregnant pediatric patients with SCD who either had received many RBC transfusions or had never received any transfusions. Serum was tested for antibodies to platelet-specific glycoproteins using a commercial enzyme immunoassay. Platelet-specific glycoprotein antibodies were found in 12 of 90 patients (13%) in the transfused group versus 5 of 24 patients (21%) in the never transfused group (p = 0.35). The prevalence of antibodies as well as the median standardized optical density for these two groups was not significantly different for any of the studied platelet glycoprotein antigens. There was no association with the presence of platelet-specific glycoprotein antibodies with either RBC or HLA antibodies. Leukocyte-reduced RBC transfusions do not appear to induce platelet-specific glycoprotein antibodies. The positive platelet-specific glycoprotein antibody results from this study may represent platelet autoantibodies, platelet alloantibodies, or false-positive reactions. A better understanding of the immunobiology of patients with SCD at baseline and after blood product exposure may help improve future transfusion and transplantation. © 2016 AABB.

A strong association has been established between migraine and depression. However, this is the first study to differentiate in a large sample of migraine patients for symptom dimensions of the affective disorder spectrum. Migraine patients (n=3174) from the LUMINA (Leiden University Medical Centre Migraine Neuro-analysis Program) study and patients with current psychopathology (n=1129), past psychopathology (n=477), and healthy controls (n=561) from the NESDA (Netherlands Study of Depression and Anxiety) study, were compared for three symptom dimensions of depression and anxiety. The dimensions -lack of positive affect (depression specific); negative affect (nonspecific); and somatic arousal (anxiety specific)- were assessed by a shortened adaptation of the Mood and Anxiety Symptom Questionnaire (MASQ-D30). Within the migraine group, the association with migraine specific determinants was established. Multivariate regression analyses were conducted. Migraine patients differed significantly (p<0.001) from healthy controls for all three dimensions: Cohen's d effect sizes were 0.37 for lack of positive affect, 0.68 for negative affect, and 0.75 for somatic arousal. For the lack of positive affect and negative affect dimensions, migraine patients were predominantly similar to the past psychopathology group. For the somatic arousal dimension, migraine patients scores were more comparable with the current psychopathology group. Migraine specific determinants for high scores on all dimensions were high frequency of attacks and cutaneous allodynia during attacks. This study shows that affective symptoms in migraine patients are especially associated with the somatic arousal component. Copyright © 2015 Elsevier Inc. All rights reserved.

Patients in the early stage of hypertensive heart disease tend to have normal echocardiographic findings. The aim of this study was to investigate whether pathology-specific echocardiographic morphologic and functional parameters can help to detect subclinical hypertensive heart disease. One hundred ten consecutive patients without a history and medication for arterial hypertension (AH) or other cardiac diseases were enrolled. Standard echocardiography and two-dimensional speckle-tracking-imaging analysis were performed. Resting blood pressure (BP) measurement, cycle ergometer test (CET), and 24-hour ambulatory BP monitoring (ABPM) were conducted. Patients were referred to "septal bulge (SB)" group (basal-septal wall thickness ≥ 2 mm thicker than mid-septal wall thickness) or "no-SB" group. Echocardiographic SB was found in 48 (43.6%) of 110 patients. In this SB group, 38 (79.2%) patients showed AH either by CET or ABPM. In contrast, in the no-SB group (n = 62), 59 (95.2%) patients had no positive test for AH by CET or ABPM. When AH was solely defined by resting BP, SB was a reasonable predictive sign for AH (sensitivity 73%, specificity 76%). However, when AH was confirmed by CET or ABPM the echocardiographic SB strongly predicted clinical AH (sensitivity 93%, specificity 86%). In addition, regional myocardial deformation of the basal-septum in SB group was significantly lower than in no-SB group (14 ± 4% vs. 17 ± 4%; P < .001). In conclusion, SB is a morphologic echocardiographic sign for early hypertensive heart disease. Sophisticated BP evaluation including resting BP, ABPM, and CET should be performed in all patients with an accidental finding of a SB in echocardiography. Copyright © 2016 The Authors.

To investigate the impact of age on the clinicopathological features and survival of patients with gastric cancer (GC), and hope to better define age-specific patterns of GC and possible associated risk factors.Using the surveillance, epidemiology, and end results (SEER) database to search the patients who diagnosed GC between 2007 and 2011 with a known age. The overall and 5-year gastric cancer specific survival (CSS) data were obtained using Kaplan-Meier plots. Multivariable Cox regression models were built for the analysis of long-term survival outcomes and risk factors.A total of 7762 GC patients treated with surgery during the 4-year study period were included in the final study cohort. We divided into five subgroups according to the different age ranges. The overall 5-year cause-specific survival (CSS) was 60.3% in Group 1 (below 45 years), 60.3% in the Group 2 (45-55 years), 61.2% in Group 3 (56-65 years), 59.2% in Group 4 (66-75 years), and 59.2% in Group 5 (older than 76 years). Kaplan-Meier plots showed that patients older than 76 years had the worst 5-year CSS of 56.0% rate in all the subgroups. Age, tumor size, primary site, histological type, and Tumor Node Metastasis stage were identified as significant risk factors for poor survival on univariate analysis (all P < 0.001, log-rank test). Additionally, as the age increased, the risk of death for GC demonstrated a significant increase.In conclusion, our analysis of the SEER database revealed that the prognosis of GC varies with age. Patients at age 56 to 65 group have more favorable clinicopathologic characteristics and better CSS than other groups.

We aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome and its variants. The lack of specifically designed stents has led to off-label use of coronary, biliary, or peripheral stents in the neonatal ductus arteriosus. Recently, a self-expanding stent, specifically designed for use in hypoplastic left heart syndrome, has become available. We carried out a retrospective cohort comparison of 69 neonates who underwent hybrid ductal stenting with balloon-expandable and self-expanding stents from December, 2005 to July, 2014. In total, 43 balloon-expandable stents were implanted in 41 neonates and more recently 47 self-expanding stents in 28 neonates. In the balloon-expandable stents group, stent-related complications occurred in nine patients (22%), compared with one patient in the self-expanding stent group (4%). During follow-up, percutaneous re-intervention related to the ductal stent was performed in five patients (17%) in the balloon-expandable stent group and seven patients (28%) in self-expanding stents group. Hybrid ductal stenting with self-expanding stents produced favourable results when compared with the results obtained with balloon-expandable stents. Immediate additional interventions and follow-up re-interventions were similar in both groups with complications more common in those with balloon-expandable stents.

Whether shock wave therapy or shock wave therapy combined with plantar fascia-specific stretching is more efficient in treating chronic plantar heel pain remains unclear. The aim of the study was to test the null hypothesis of no difference of these two forms of management for patients who had unilateral plantar fasciopathy for a minimum duration of twelve months and which had failed at least three other forms of treatment. One hundred and fifty-two patients with chronic plantar fasciopathy were assigned to receive repetitive low-energy radial shock-wave therapy without local anesthesia, administered weekly for three weeks (Group 1, n = 73) or to receive the identical shock wave treatment and to perform an eight-week plantar fascia-specific stretching program (Group 2, n = 79). All patients completed the nine-item pain subscale of the validated Foot Function Index and a subject-relevant outcome questionnaire. Patients were evaluated at baseline, and at two, four, and twenty-four months after baseline. The primary outcome measures were a mean change in the Foot Function Index sum score at two months after baseline, a mean change in item 2 (pain during the first steps of walking in the morning) on this Index, and satisfaction with treatment. No difference in mean age, sex, weight or duration of symptoms was found between the groups at baseline. At two months after baseline, the Foot Function Index sum score showed significantly greater changes for the patients managed with shock-wave therapy plus plantar fascia-specific stretching than those managed with shock-wave therapy alone (p < 0.001), as well as individually for item 2 (p < 0.001). Twenty-four patients in Group 1 (32%) versus forty-seven patients in Group 2 (59%) were satisfied with the treatment (p < 0.001). Significant differences persisted at four months, but not at twenty-four months. A program of manual stretching exercises specific to the plantar fascia in combination with repetitive low-energy radial shock-wave therapy is more efficient than repetitive low-energy radial shock-wave therapy alone for the treatment of chronic symptoms of proximal plantar fasciopathy.

The aim of this study was to analyze first intraoperative alignment and reason to abandon the use of patient-specific instrumentation using intraoperative CAS measurement, secondly assess by postoperative CT analysis if CI, based on preoperative 3D-MRI data, improved postoperative component positioning (including femoral rotation) and lower limb alignment as compared with results obtained with CAS. In this randomized controlled trial, 80 consecutive patients scheduled to undergo TKA were enrolled. Eligible knees were randomized to the group of PSI-TKAs (n = 40) or to the group of CAS-TKAs (n = 40). In the CAS group, CAS determined and controlled cutting block positioning in each plane. In the PSI group, CAS allowed to measure adequacy of intraoperative alignment including femoral component rotation. At 3 months after surgery, implants position were measured and analyzed with full-weight bearing plain radiographs and CT scan. Intraoperatively, there was a significant difference concerning Sagittal Femoral mechanical, Frontal tibial mechanical angle and tibial slope between the two groups (respectively p = 0.01, p = 0.02, p = 0.046). Custom instrumentation was abandoned intraoperatively in seven knees (17.5 %). Abnormal tibial cuts were responsible of the abandon in three out of seven cases, femoral cut in 1/7 and dual abnormalities in 3/7. Postoperatively, tibial slope outliers percentage was higher in the patient specific instrumentation group with six patients (18.18 %) versus one patient (2.5 %) in the CAS group (p = 0.041). Patient specific instrumentation was associated with an important number of hazardous cut and a higher rate of outliers in our series and thus should be used with caution as related to. This study is the first to our acknowledgement to compare intra-operative ancillary and implant positioning of PSI-TKA and CAS-TKA. High rate of malposition are sustained by our findings, as such PSI-TKA should be used with caution, by surgeons capable to switch to conventional instrumentation intra-operatively.

To determine the importance of fasting calcium/creatinine ratio in patients with calcium stones and its relation with hypercalciuria and phospho-calcium metabolism. Cross-sectional study including 143 patients divided into two groups according to fasting calcium/creatinine. Group 1: 66 patients (calcium/ creatinine<0.11); Group 2: 77 patients (calcium/ creatinine>0.11). A comparative study is performed between groups including phospho-calcium metabolism parameters and excretion of urinary lithogenic markers. Linear correlation studying calciuria and fasting calcium/ creatinine was performed. SPSS 17.0 statistical analysis software was used, considering p≤0.05. It is noteworthy that group 2 had increased 24 h urine calcium excretion in comparison to group 1 (229.3 vs 158.1; p=0.0001) and calcium/citrate (0.47 vs 0.34; p=0.001). There is a positive and significant correlation between calcium levels in 24 h urine and fasting calcium/creatinine (R=0.455; p=0.0001) and a cutoff is set at 0.127 (sensitivity 72%, specificity 66%) to determine hypercalciuria (>260 mg in 24 h). Increased fasting calcium/creatinine determines increased 24 hours calcium excretion, although the sensitivity and specificity to determine hypercalciuria is not high.

In this study we investigated the erectile function status of men presenting with Peyronie's disease. Demographics of patients regarding age, duration of PD, nature of deformity and comorbidities were compared between the patients with PD, with and without erectile dysfunction. Patients with erectile dysfunction underwent dynamic infusion cavernosometry/cavernosography. The hemodynamic profile of patients presenting with combined PD and ED were analyzed and compared between those with onset of ED before and after diagnosis of PD. Of the 222 patients 78 had ED (35%) by self-report at presentation. The mean age of patients with PD and ED was 52 +/- 22 years old. Hypertension (71.5%), hyperlipidemia (60.4%) and smoking (49.2%) were the leading comorbidities in the entire group. Statistically significant differences were found between the groups with and without ED for hypertension (p = 0.02) and cigarette smoking (p = 0.009). Of 222 patients 45 (20%) had ED that predated PD onset (group 1) and 33 (15%) had ED that postdated the onset of PD (group 2). DICC showed normal hemodynamics in 14 of 78 patients (18%), arteriogenic insufficiency in 50 (64%) and corporoveno-occlusive dysfunction in 16 (20%). CVOD was evenly distributed between groups 1 and 2, whereas arteriogenic ED was significantly higher in group 1 (82%). Site specific leak was seen in 4 of 33 (12%), all group 2 patients. Patients in whom ED postdates the onset of PD are more likely to have normal erectile hemodynamics. Site specific leak is an uncommon contributor to PD and is seen only in the patients with PD in whom ED postdated PD onset. The leading vascular etiology of ED in PD is arteriogenic in older patients and those with greater associated comorbidities.

Task specific grip force control in writer's cramp.

2014-04-01

Writer's cramp is defined as a task specific focal dystonia generating hypertonic muscle co-contractions during handwriting resulting in impaired writing performance and exaggerated finger force. However, little is known about the generalisation of grip force across tasks others than writing. The aim of the study was to directly compare regulation of grip forces during handwriting with force regulation in other fine-motor tasks in patients and control subjects. Handwriting, lifting and cyclic movements of a grasped object were investigated in 21 patients and 14 controls. The applied forces were registered in all three tasks and compared between groups and tasks. In addition, task-specific measures of fine-motor skill were assessed. As expected, patients generated exaggerated forces during handwriting compared to control subjects. However there were no statistically significant group differences during lifting and cyclic movements. The control group revealed a generalisation of grip forces across manual tasks whereas in patients there was no such correlation. We conclude that increased finger forces during handwriting are a task-specific phenomenon that does not necessarily generalise to other fine-motor tasks. Force control of patients with writer's cramp in handwriting and other fine-motor tasks is characterised by individualised control strategies.

1996-05-01

To determine the distribution of antibodies to streptokinase that might be anticipated in patients requiring treatment with streptokinase, specific anti-streptokinase antibody titres were determined in a group of subjects from the general population and in a group of patients presenting with acute myocardial infarction. Enzyme-linked immunosorbent assays were developed to measure specific anti-streptokinase IgG and subclass IgG1 in 95 subjects from the general population and in 160 patients presenting with acute myocardial infarction. Low titres of IgG1 were found in both the general population (median = 5; range: 0-490) and in the myocardial infarction group (median = 7; range: 0-2000). A minority of subjects in both groups had high titres. The findings suggest that low titres of antibody are widespread in the population. The minority of subjects in both groups who had high titres may explain the infrequent type III immune reactions encountered with streptokinase.

[Ethnic origin of patients remains important].

PubMed

Stronks, Karien

2013-01-01

The ethnic diversity in medical practices is increasing rapidly. In the Netherlands, ethnic groups are predominantly defined on the basis of their geographical origin, e.g. inhabitants of Turkish, Moroccan or Surinamese origin. The prevalence of health problems and the utilisation of health care differ between ethnic groups. This ethnic variation arises, firstly, from characteristics that are inherent to these groups such as genetic profile and culture, and, secondly, from characteristics that reflect their position in Dutch society such as socio-economic position and discrimination on the other. If we could fully understand which of these specific characteristics leads to a specific pattern of health problems or health care use, the classification of patient into ethnic groups would then become redundant. As long as we do not completely understand this variation, however, ethnic origin is a good entry-point for targeting health care to groups of patients.

The primary objective was to identify specific groups of patients with a first-episode psychosis based on family history, obstetric complications, neurological soft signs, and premorbid functioning. The secondary objective was to relate these groups with cognitive variables. A total of 62 first-episode psychoses were recruited from adult and child and adolescent mental health services. The inclusion criteria were patients between 7 and 65 years old (real range of the samples was 13-35 years old), two or more psychotic symptoms and less than one year from the onset of the symptoms. Premorbid functioning (PAS), soft signs (NES), obstetric complications and a neuropsychological battery (CPT, TMTA/TMTB, TAVEC/TAVECI, Stroop, specific subtest of WAIS-III/WISC-IV) were administered. We found three clusters: 1) higher neurodevelopment contribution (N=14), 2) higher genetic contribution (N=30), and 3) lower neurodevelopment contribution (N=18). Statistical differences were found between groups in TMTB, learning curve of the TAVEC, digits of the WAIS and premorbid estimated IQ, the cluster 1 being the most impaired. A cluster approach could differentiate several groups of patients with different cognitive performance. Neuropsychological interventions, as cognitive remediation, should be addressed specifically to patients with more impaired results. © 2013 Elsevier B.V. All rights reserved.

Is there any influence of personality disorder on the short term intensive group cognitive behavioral therapy of social phobia?

2011-03-01

The treatment of personality disorder is repeatedly reported as less successful than the treatment of patients without personality disorder. Most clinicians believe that anxiety disorder in tandem with a personality disorder often leads to longer treatment, worsens the prognosis, and thus increases treatment costs. Our study was designed to compare the short-term effectiveness of therapy in patients suffering from social phobia with and without personality disorder. The specific aim of the study was to assess the efficacy of a 6 week therapeutic program designed for social phobia (SSRIs and CBT) in patients suffering from social phobia with comorbid personality disorder (17 patients) and social phobia without comorbid personality disorder (18 patients). The patients were regularly assessed in weeks 0, 2, 4 and 6 using the CGI (Clinical Global Improvement) for severity, LSAS (Liebowitz Social Anxiety Scale), and in self-assessments BAI (Beck Anxiety Inventory) and BDI (Beck Depression Inventory). Patients in both groups improved their scores in most of the assessment instruments used. A combination of CBT and pharmacotherapy proved to be the most effective treatment for patients suffering with social phobia with or without comorbid personality disorder. Treatment efficacy in patients with social phobia without personality disorder was significantly better than in the group with social phobia comorbid with personality disorder for CGI and specific inventory for social phobia - LSAS. The scores on the subjective depression inventory (BDI) also showed significantly greater decrease over the treatment in the group without personality disorder. The treatment effect between groups did not differ in subjective general anxiety scales BAI. Our study showed that patients suffering from social phobia and comorbid personality disorder showed a smaller decrease in specific social phobia symptomatology during treatment compared than patients with social phobia without personality disorders. However, a significant decrease in symptomatology occurred in personality disorder patients as well.

The aim of this study was to investigate the presence and distribution of anti-toxoplasma-specific IgM and IgG tantibodies in patients suspected to have toxoplasmosis and investigate for any association between IgM and IgG antibodies and some toxoplasmosis risk factors as well. In a comparative cross-sectional study, 70 patients suspected to had active toxoplasmosis and 30 control volunteers, who gave informed consent, entered the study. In each group, patient age, sex, signs of appearance, education level, residency status (urban / rural), occupation, frequency of toxoplasma-specific IgG and IgM antibodies, abortion history, and some risk factors (Direct cat exposure, Occupational exposure to raw meat, and Raw vegetable consumption) were recorded. The enzyme-linked immunosorbent assay (ELISA) kits (EUROIMMUN(®), United Kingdom) were used for the evaluation of anti-toxoplasma IgG and IgM antibodies according to the manufacturer's instructions. All analyses were done using SPSS-20. The frequency of toxoplasma-specific IgG and IgM antibodies like: Direct cat exposures, Occupational exposure to raw meat, and Raw vegetable consumption were not statistically significant between the two groups (P > 0.05). The history of previous abortions in women in the toxoplasmosis-suspected group was significantly higher than that in the controls (31.4% versus 6.7%; P = 0.009). The frequency of specific IgM and IgG antibodies in toxoplasmosis suspected in the toxoplasmosis and control groups was not statistically significant.

Fasting in Ramadan has adverse effects on health of Muslims with diabetes. Key strategies to prepare the patients are to provide appropriate health education to the patients prior to Ramadan and to adjust anti-diabetic medicines during Ramadan. To study outcomes of the specific health care services that providing health education in parallel with counseling by Islamic leader The Thai Muslims with type 2 diabetes mellitus were divided into two groups. There were 62patients in experimental group that was provided with specific health care service for Thai Muslims with diabetes in which health education prior to Ramadan and adjustment ofanti-diabetic medicine applied. The other was control group with 28patients that was provided only with original health care service. The results were monitored after Ramadan by interviews, weight and waist measurements, blood pressure measurement and blood tests. Both mean systolic and diastolic blood pressure were well controlled in both groups and slightly decreased after Ramnadan. The mean diastolic blood pressure of the experimental group decreased after Ramadan (p-value = 0.041). From behavior point of view, it was found that the patients in the experimental group had consumed less sweetenedfood (p-value = 0.002). There was no incidence ofsevere hypoglycemia in either experimental or control group. The number and portion of patients with hypoglycemic symptoms in experimental group were lower than those in controlled group (p-value = 0.013). Specific health care service by providing health education prior to Ramadan and adjustment ofanti-diabetic medicine application resulted in a positive effect as the patients tended to consume less sweetenedfood to keep blood sugar level in control. Fasting could affect the patients 'health in apositive way as it helps to control blood pressure, while in parallel, adjustment of anti-diabetic medicine application helps to prevent hypoglycemia. This health care service, which can be achieved in collaboration with a health care team and Islamic leaders, is useful and suitable for Thai Muslims with diabetes mellitus type 2.

Oral desensitization in children allergic to cow's milk proteins is not risk free. The analysis of factors that may influence the outcome is of utmost importance. To analyze the efficacy and safety of the oral desensitization according to specific IgE (sIgE) level and adverse events during the maintenance phase. Thirty-six patients allergic to cow's milk (mean age, 7 years) were included in an oral desensitization protocol. Patients were grouped according to sIgE levels (ImmunoCAP) into groups 1 (sIgE <3.5 kU/L), 2 (3.5-17 kU/L), and 3 (>17-50 kU/L). Nineteen children were included as a control group. Serum sIgE levels to cow's milk and its proteins were determined at inclusion and 6 and 12 months after finishing the desensitization protocol. Thirty-three of 36 patients were successfully desensitized (200 mL): 100% of group 1 and 88% of groups 2 and 3. Desensitization was achieved in a median of 3 months (range, 1-12 months); 90% of the patients in group 1, 50% of the patients in group 2, and 30% of the patients in group 3 achieved tolerance in less than 3 months (P = .04). In the control group only 1 child tolerated milk in oral food challenge after 1 year. During the induction phase, there were 53 adverse events in 27 patients (75%). Patients of groups 2 and 3 had more severe adverse events compared with group 1. During the maintenance phase, 20 of 33 patients (60%) had an adverse event. Oral desensitization is efficacious. Tolerance is achieved earlier when sIgE is lower. Severe adverse events are frequent, especially in patients with higher sIgE levels.

Improvement of communication skills in nursing home staff is key to provide better care for dementia patients and decrease occupational mental stress. An innovative train-the-trainer program to improve and maintain professional caregivers' social competencies in nursing home dementia care is described. Over a period of 6 months, a group of 6 senior staff members were qualified as program trainers (multiplicators) for the TANDEM training program, which qualified them to design, deliver, and evaluate training sessions that foster specific social competencies in dementia care. In a subsequent intervention study with 116 geriatric caregivers in 14 nursing homes, training was provided either by multiplicators (intervention group) or directly by project coworkers (control group). Participants in both groups improved their dementia-specific communication skills. In a follow-up survey, the intervention group also reported lasting reductions in mental stressors at work (p < 0.05) and occupational mental stress (p < 0.01) compared with the control group. The qualification of staff members in German nursing homes to be multiplicators for the TANDEM train-the-trainer program for dementia-specific communication skills has a beneficial influence on social competencies, mental stressors at work, and occupational mental stress of staff who care for dementia patients and may contribute to a sustainable implementation of dementia-specific social competencies.

Several prospective studies into the effects of adjuvant systemic therapy on cognitive functioning suggest that a proportion of breast cancer patients show cognitive deficits already before the start of systemic therapy. Owing to, among others, methodological inconsistency, studies report different rates of this pre-treatment cognitive impairment. We examined the impact of four different criteria of cognitive impairment and two types of reference groups (a study-specific healthy reference group versus published normative data) on the prevalence of cognitive impairment. Two hundred and five postmenopausal breast cancer patients underwent a battery of neuropsychological tests before the start of endocrine therapy, 124 healthy subjects underwent the same tests. Proportions of cognitive impaired patients were calculated for each of four criteria for cognitive impairment, using (1) study-specific healthy controls and (2) published norms of healthy controls as reference groups. The prevalence of cognitive impairment varied greatly with the strictness of the criterion, as expected, but also was dependent on the reference group used. Cognitive impairment, relative to published norms, ranged from 1% for the strictest to 36.6% for the less strict criterion, cognitive impairment relative to study-specific healthy controls, ranged from 13.7 to 45.4% for the same criteria. This study highlights contrasting proportions of cognitive impairment by using different criteria for cognitive impairment and different reference groups. (Dis)advantages of the methods using a criterion for cognitive impairment, and of the use of published norms versus a study-specific reference group are discussed.

Purpose Some patients with interstitial lung disease (ILD) related to connective tissue disease (CTD) have a delayed diagnosis of the underlying CTD when the ILD is categorized as idiopathic. In this study, we evaluated the frequency of myositis autoantibodies in patients diagnosed with idiopathic ILD and investigated the clinical significance stemming from the presence of the antibodies. Materials and Methods A total 32 patients diagnosed with idiopathic ILD were enrolled in this study. We analyzed a panel of 11 myositis autoantibody specificities in the patients using a line blot immunoassay. Then, we divided them into myositis autoantibody-positive and -negative groups and compared the clinical features and laboratory data between the two groups. Results Of the 32 idiopathic ILD patients, 12 patients had myositis autoantibodies encompassing 9 specificities, except for anti-Mi-2 and anti-PM-Scl 100 (12/32, 38%). Anti-synthetase autoantibodies including Jo-1, EJ, OJ, PL-7, and PL-12 were present in 7 patients (7/32, 22%). The group with myositis autoantibodies presented more frequently with the symptom of mechanic's hand and showed abnormal pulmonary function test results with low forced vital capacity, diffusing capacity for carbon monoxide, total lung capacity, and high lactate dehydrogenase values in blood when compared with the group without myositis antibodies. Conclusion We strongly suggest that patients undergo an evaluation of myositis autoantibodies, if they are diagnosed with idiopathic ILD in the presence of clinical characteristics including mechanic's hand, arthralgia, and autoantibodies which are insufficient to make a diagnosis of a specific CTD category.

C-reactive protein (CRP) plays an important role on inflammatory processes associated to the metabolic syndrome (MS), alike of insulin sensitivity, endothelial dysfunction and fibrinolysis insufficiency. Alanine aminotransferase (ALT) may be a sensible marker for the diagnosis of hepatic damage and has therefore been used as an alternative method for the noninvasive diagnosis of non-alcoholic fatty liver disease (NAFLD), especially in epidemiological studies. At the present time, the possible utility of high sensitivity CRP (hsCRP) as a simple measure to detect the degree of hepatic inflammatory response during the development NAFLD in MS has not been explored. To evaluate the measurement of serologic hsCRP for the identification of hepatic inflammatory response in patients with MS. Seven hundred and forty persons (526 men and 214 women), mean age 45 +/- 11 years who were asymptomatic and otherwise seeming healthy in whom a medical questionnaire was applied underwent physical examination, laboratory testing, hepatic ultrasound and measurement of hsCRP by the immuno-turbidimetric method. Receiver operating characteristic (ROC) analysis was used to evaluate the sensitivity and specificity of all possible hsCRP for detecting different degrees of hepatic inflammation (ALT > 44 U/L and ALT > 88 U/L). Patients were stratified according to the presence of metabolic syndrome (MS) and ALT concentration in three groups: Group I, having MS and ALT > 44 U/L (n = 39); Group II, having ALT > 44 U/L without MS (n = 105) and Group III, having ALT < or = 44 U/L without MS (n = 596). The optimal hsCRP cut-off for detecting patients with ALT 44 U/L was 2.5 mg/L (sensibility 66%; specificity 50%) and for detecting patients with ALT > 88 U/L was 2.35 (sensibility 72%; specificity 59%). hsCRP serum concentrations in Group I were significantly higher than in Group II and Group III (p < 0.05) but no difference was found between Group II and Group III (Group I = 6.0 +/- 6.7 mg/L vs. Group II = 2.8 +/- 3.1 mg/L, vs. Group III = 2.9 +/- 4.1 mg/L). ALT concentrations were also significantly higher in Group I than in Group II and Group III, (p < 0.05) and a difference between Group II and Group III (p < 0.05) was also found (Group I = 72 +/- 31 U/L vs. Group II = 64 +/- 29 U/L vs. Group III = 24 +/- 8 U/L). These results suggest that the measurement of hsCRP for the identification of hepatic inflammatory response in patients with MS with NAFLD is limited because of its low sensibility and specificity observed on identifying different degrees of hepatic inflammation.

We want to review the value of 18-fluoro-deoxy-glucose positron emission tomography for response prediction of primary tumor in patients with esophageal cancer during or after neoadjuvant chemoradiotherapy. Studies were searched in Pubmed, Embase and Cochrane Library with specific search strategy. The published articles were included according to the criteria established in advance. The included studies were divided into two groups according to the time of the repeat positron emission tomography: during (Group A) or after neoadjuvant chemoradiotherapy (Group B). The studies that performed the repeat positron emission tomography after neoadjuvant chemoradiotherapy were graded Quality Assessment of Diagnostic Accuracy Studies. The pooled sensitivity, specificity and diagnostic odds ratio were obtained for both groups on the basis of no-existing of threshold effect. Fifteen studies were included in the present study. The threshold effect did not exist in both groups. The pooled sensitivity, specificity and diagnostic odds ratio were 85%, 59%, 6.82 with 95% confidence interval 76-91%, 48-69%, 2.25-20.72 in Group A. The equivalent values were 67%, 69%, 6.34 with 95% confidence interval 60-73%, 63-74%, 2.08-19.34 in Group B. The pooled sensitivity was 90% in four studies that enrolled patients with esophageal squamous cell carcinoma merely in Group B. According to the present data, positron emission tomography should not be used routinely to guide treatment strategy in esophageal cancer patients. We speculated that positron emission tomography could be used as a tool to predict treatment response after neoadjuvant chemoradiotherapy in patients with esophageal squamous cell carcinoma. © The Author 2016.

The Directigen Group A Strep Test (DGAST), a new rapid method of detecting group A beta-hemolytic streptococci directly from throat swabs, was compared with a traditional culture technique for the detection of group A beta-hemolytic streptococci. Five hundred oropharyngeal swabs from pediatric and adult patients were cultured and then processed by using the DGAST. Of the 144 specimens positive by culture, 131 were DGAST positive (sensitivity, 90.9%). Of the 356 specimens negative by culture, 353 were DGAST negative (specificity, 99.2%). Twelve of the 13 false-negative DGAST results were from pediatric patients. One hundred isolates of non-group A beta-hemolytic streptococci were recovered, primarily groups C, F, and G. The DGAST is easy to perform, rapid, sensitive, and very specific for detection of group A beta-hemolytic streptococci directly from swabs. Supplementing the DGAST with a culture on a 5% sheep blood agar plate would enhance detection of group A beta-hemolytic streptococci, especially in pediatric patients. PMID:6386884

Conventional diagnostic tests in allergy are insufficient to clarify the cause of vernal conjunctivitis. Component-resolved diagnostic (CRD) by microarray allergen assay may be useful in detecting allergens that might be involved in the inflammatory process. In a recent trial in patients suffered from eosinophilic esophagitis, after 2 years of the CRD-guided exclusion diet and specific immunotherapy, significant clinical improvement was observed, and 68% of patients were discharged (cure based on negative biopsy, no symptoms, and no medication intake). Our new objective was to evaluate IgE-mediated hypersensitivity by CRD in tears and serum from patients with vernal conjunctivitis and treat patients with identified triggering allergens by specific immunotherapy. Twenty-five patients with vernal conjunctivitis were evaluated. The identified triggering allergens were n Lol p 1 (11 cases), n Cyn d 1 (eight cases), group 4 and 6 grasses (six cases) and group 5 of grasses (five cases). Prick test and pollen IgE were positive in one case. Clinical improvement was observed in 13/25 vernal conjunctivitis patients after 1-year specific immunotherapy. CRD seems to be a more sensitive diagnostic tool compared with prick test and IgE detection. Specific CRD-led immunotherapy may achieve clinical improvements in vernal conjunctivitis patients.

SUMMARY Purpose The aim of this retrospective case-control study was to identify, in a group of growing children and adolescents affected by malocclusion, specific dento-skeletal characteristics which could be correlated to the onset, in the above-mentioned subjects, of craniomandibular disorders (CMD). Materials and methods Among the patients treated at the Paedodontics and Orthodontics department of Bari Dental School, we recruited a group of patients with malocclusion and symptoms of temporomandibular disorders, as an experimental group. We considered as controls those patients who, match-paired to their skeletal class depending on the ANB angle, did not show any CMD sign or symptom. Results Of the 128 examined patients, 15 showed signs and/or symptoms of CMD (11.7%). When compared to 15 patients non-affected by CMD, we could not detect statistically significant differences in both skeletal and occlusal characteristics. It is still interesting to notice how in CMD patients, characteristics of skeletal hyperdivergence are often to be found. Conclusions The present study seems to confirm that in growing children and adolescents, the presence of signs and/or symptoms of CMD is not associable to a specific vertical skeletal growth pattern or to other specific occlusal characteristics.

to determine whether the activity of tuberculous inflammation is associated with different clinical forms of drug-resistant pulmonary tuberculosis. The material taken from 310 patients operated on in 2010-2015 were retrospectively examined. The patients underwent economical lung resections of limited extent (typical and atypical ones of up to 3 segments) for circumscribed forms of tuberculosis with bacterial excretion. A study group consisted of 161 (51.9%) patients with drug-resistant variants of pulmonary tuberculosis. A control group included 149 (48.1%) patients with preserved susceptibility of Mycobacterium tuberculosis to anti-TB drugs. The activity of specific changes in tuberculosis was morphologically evaluated in accordance with the classification proposed by B.M. Ariel in 1998. The highest activity of fourth-to-fifth degree specific inflammation, including that outside the primary involvement focus, was obtained in the drug-resistant pulmonary tuberculosis group due to the predominance of patients with cavernous and fibrous-cavernous tuberculosis versus those in whom the susceptibility to chemotherapeutic agents was preserved. A macroscopic study showed that the primary lesion focus had a median size in one-half of the all the examinees; but large tuberculomas, caverns, and fibrous caverns over 4 cm in diameter were multiple and detected in the drug-resistant pulmonary tuberculosis group. Multidrug resistance was observed in more than 60% of the patients with fibrous-cavernous pulmonary tuberculosis, extensive drug resistance was seen in those with cavernous tuberculosis, which is an aggravating factor. The data obtained from the morphological study of the intraoperative material can specify the clinical form of tuberculosis and evaluate the efficiency of preoperative specific therapy. The highest activity of specific inflammation was observed in patients with multiple drug-resistant pulmonary tuberculosis, the prevalence of third-to-fourth degree specific changes was seen in those with multiple and extensively drug-resistant tuberculosis. The findings suggest that the activity of tuberculous inflammation is associated with different clinical forms of drug-resistant tuberculosis and with a spectrum of drug resistance.

To compare the effectiveness of treatment for ocular toxoplasmosis with pyrimethamine + clindamycin (or sulfadiazine) + a corticoid (Group 1), or azithromycin or a combination of azithromycin with a corticoid or a corticoid alone (Group 2). To determine the relapse rate depending on the treatment approach. A total of 25 patients treated for ocular toxoplasmosis over the last five years (2008-2013) were analyzed. Group 1 comprised 16 patients (3 were excluded) and Group 2 consisted of 6 patients. Visual improvement was more rapid in Group 1 (day 10.7) than in Group 2 (significant improvement on day 29.6). There were 5 cases of relapse in Group 1; in 13 cases, no relapse was noted; all patients in Group 2 relapsed (a total of 13 relapses). Twenty-three patients were positive for specific IgG antibodies. According to our experiences, pyrimethamine + clindamycin (or sulfadiazine) + a corticoid should be the treatment of choice in patients with ocular toxoplasmosis.

PURPOSE The purpose of this study was to evaluate patient outcomes in the National Demonstration Project (NDP) of practices’ transition to patient-centered medical homes (PCMHs). METHODS In 2006, a total of 36 family practices were randomized to facilitated or self-directed intervention groups. Progress toward the PCMH was measured by independent assessments of how many of 39 predominantly technological NDP model components the practices adopted. We evaluated 2 types of patient outcomes with repeated cross-sectional surveys and medical record audits at baseline, 9 months, and 26 months: patient-rated outcomes and condition-specific quality of care outcomes. Patient-rated outcomes included core primary care attributes, patient empowerment, general health status, and satisfaction with the service relationship. Condition-specific outcomes were measures of the quality of care from the Ambulatory Care Quality Alliance (ACQA) Starter Set and measures of delivery of clinical preventive services and chronic disease care. RESULTS Practices adopted substantial numbers of NDP components over 26 months. Facilitated practices adopted more new components on average than self-directed practices (10.7 components vs 7.7 components, P=.005). ACQA scores improved over time in both groups (by 8.3% in the facilitated group and by 9.1% in the self-directed group, P <.0001) as did chronic care scores (by 5.2% in the facilitated group and by 5.0% in the self-directed group, P=.002), with no significant differences between groups. There were no improvements in patient-rated outcomes. Adoption of PCMH components was associated with improved access (standardized beta [Sβ]=0.32, P = .04) and better prevention scores (Sβ=0.42, P=.001), ACQA scores (Sβ=0.45, P = .007), and chronic care scores (Sβ=0.25, P =.08). CONCLUSIONS After slightly more than 2 years, implementation of PCMH components, whether by facilitation or practice self-direction, was associated with small improvements in condition-specific quality of care but not patient experience. PCMH models that call for practice change without altering the broader delivery system may not achieve their intended results, at least in the short term. PMID:20530395

To investigate the cost-effectiveness of standardized specific immunotherapy (SIT) for allergic rhinitis patients accompanied with asthma (ARAS) in China. Forty ARAS patients sensitized with house dust mite (HDM) were administered with SIT (SIT group) or merely medicine treatment (control group). Alutard dermatophagoides pteronyssinus vaccine from ALK company was used for immunotherapy. The usage of symptom control medicine was according to the ARIA and GINA guideline. Cost-effectiveness ratio (CER) and Incremental cost-effectiveness ratio(ICER) analysis was conducted. The effectiveness was measured in terms of symptom scores, quality of life, objective improvement of rhinitis and asthma. Sensitive analysis was conducted to verify the stability of the results. The cost of SIT group for 1 year (6578 yuan) was higher than that of control group (1733.3 yuan), while the cost-effectiveness ratio and incremental cost-effectiveness ratio of SIT group were significant better than that of control group in all items. CER was 1686.7 yuan in SIT group compared with 3466.6 yuan in control group for nasal symptom scores, 4698.6 yuan in SIT group compared with 5777.8 yuan in control group for asthma symptom scores, 3462.1 yuan in SIT group compared with 8666.7 yuan in control group. The sensitive analysis of the price 10 percent higher or lower showed the same results. The cost-effectiveness of specific immunotherapy (SIT) for mite sensitized ARAS patients was better than that of merely medicine treatment.

Assisted hatching in reproduction techniques has improved the successful implantation rates in certain groups of patients with poor prognosis. This study focuses on its effect in groups of patients with previous implantation failure and according to age groups. Compare the pregnancy rates of patients who turned to this technique following an implantation failure using in vitro fertilization with those of patients who did not use assisted hatching before another attempt of in vitro fertilization and according to specific age groups. Cases of patients using assisted hatching in our Center between January 2008 and December 2009 were studied. The results were compared in terms of age in three groups: group I, >35 years; group II, 35-39 years, and group III, > 40 years. Patients in group II had better pregnancy rate (30%) than those in groups I and III (16.98 and 20.83%, respectively). When comparing the results of the group of patients using assisted hatching with those of the group that did not, the first reported a 20% pregnancy rate versus no pregnancy in the other group.

There is a need for a disease-specific instrument for assessing health-related quality of life in adults with hereditary angioedema due to C1 inhibitor deficiency, a rare, disabling and life-threatening disease. In this paper we report the protocol for the development and validation of a specific questionnaire, with details on the results of the process of item generation, domain selection, and the expert and patient rating phase. Semi-structured interviews were completed by 45 patients with hereditary angioedema and 8 experts from 8 regions in Spain. A qualitative content analysis of the responses was carried out. Issues raised by respondents were grouped into categories. Content analysis identified 240 different responses, which were grouped into 10 conceptual domains. Sixty- four items were generated. A total of 8 experts and 16 patients assessed the items for clarity, relevance to the disease, and correct dimension assignment. The preliminary version of the specific health-related quality of life questionnaire for hereditary angioedema (HAE-QoL v 1.1) contained 44 items grouped into 9 domains. To the best of our knowledge, this is the first multi-centre research project that aims to develop a specific health-related quality of life questionnaire for adult patients with hereditary angioedema due to C1 inhibitor deficiency. A preliminary version of the specific HAE-QoL questionnaire was obtained. The qualitative analysis of interviews together with the expert and patient rating phase helped to ensure content validity. A pilot study will be performed to assess the psychometric properties of the questionnaire and to decide on the final version.

Strategies are needed to help general practitioners (GPs) promote smoking cessation as recommended by guidelines. This study examines whether the quality of action planning among GPs improves their provision of smoking cessation care. The effectiveness of a 1-h training programme was examined in a cluster randomised controlled trial in which 49 GPs participated. GPs who followed the training (intervention group; n = 25) formulated action plans related to i) enquiring about smoking, ii) advising to quit smoking, and iii) arranging follow-up for smokers motivated to quit. GPs also formulated a coping plan for encountering smokers not motivated to quit. The quality of these plans (plan specificity) was rated and, 6 weeks after the training, GPs reported on the performance of these plans (plan enactment). Multilevel regression analyses were used to examine the effects of plan specificity and plan enactment on patient-reported smoking cessation activities of the GPs in the intervention group (n = 1,632 patients) compared with the control group (n = 1,769 patients). Compared to the control group, GPs who formulated a highly specific action plan during the training asked their patients about smoking more often after the training compared to prior to the training (OR 2.11, 95% CI 1.51-2.95). GPs were most likely to have asked patients about smoking after the training compared to prior to the training when they had enacted a highly specific formulated action plan (OR 3.08, 95% CI 2.04-4.64). The effects of GP plan specificity and plan enactment on asking patient about smoking were most prominent among GPs who, at baseline, intended to provide smoking cessation care. A highly specific action plan formulated by a GP on when, how, and by whom patients will be asked about smoking had a positive effect on GPs' asking patients about smoking, especially when these professionals also reported to have enacted this plan. This effect was most prominent among GPs who intended to provide smoking cessation care prior to the intervention. Training in devising personalised coping plans is recommended to further increase GPs' provision of advice to quit smoking and arranging follow-up support to quit smoking.

There are about 60,000 chemical substances which may cause poisoning. Identifying the cause substances is, therefore, very important for patient at emergency department. Triage is an immunoassay kit for the qualitative test for the metabolites of 8 major abuse drugs in urine. We assessed the usefullness of Triage on two patient groups. The first Group consists of the patients considered having not taken substances at initial diagnosis; the second Group consists of the patients considered having taken substances. The result are as follows. 1) The rate of Triage positive patients in the first Group were: attempt-suicide 23%, coma 24%, shock 10%, trauma 7%, respectively. Except for the habitually used medicine, narcotic and stimulant drugs were detected. In the first Group, negative result of Triage was effective in diagnosing the patients as not poisoned, excluding the possitivity of 8 major drugs usage. 2) The rate of Triage positive patients in the second Group were very high: attempt-suicide 77%, coma 51%, shock 57%, trauma 30%, respectively, showing mostly any of 8 major drugs were the cause of poisoning. In the second Group, positive result of Triage was effective in diagnosing the patient as poisoning or as coexisting poisoning with other diseases. 3) The specificity of Triage diagnosis in the first Group was 80% (113/142). The specificity and the sensitivity in the second Group were 64% (50/78) and 97% (74/76), respectively. These results means that Triage is very useful for diagnosis on 8 major drugs poisoning. 4) Triage is efficient for identifying the cause substances in drug poisoning and, therefore, can save medical expense. Triage is a very useful test kit at emergency department.

Marital status was found to be an independent prognostic factor for survival in various cancer types, but it hasn't been studied in gastric cancer. The Surveillance, Epidemiology and End Results database was used to compare survival outcomes with marital status. A total of 16,106 eligible patients were identified. Patients in the widowed group had the highest proportion of women, more common site of stomach, more prevalence of elderly patients, higher percentage of adenocarcinoma, and more tumors at localized stage (P < 0.05). Patients in married group had better 5year cause-specific survival (CSS) than those unmarried (P < 0.05). Further analysis showed that widowed patients always presented the lowest CSS compared with that of other groups. Widowed patients had 7.1% reduction in 5-year CSS compared with married patients at Localized stage (77.2% vs 70.1%, P < 0.001), 9.6% reduction at Regional stage (38.2% vs 28.6%, P < 0.001), and 4.7% reduction at Distant stage (13.3% vs 8.6%, P < 0.001). These results showed that unmarried patients were at greater risk of cancer specific mortality. Despite favorable clinicpathological characteristics, widowed patients were at highest risk of death compared with other groups.

There has been little research which specifically examines medicine use among South Asian (SA) and Middle Eastern (ME) groups, although evidence suggests that medicine-related needs may be poorly met for these groups. To describe medicine-related problems (MRPs) experienced by SA and ME patients from their perspectives and identify possible contributory factors that may be specific to their cultures. The data were collected in seven pharmacies in London, United Kingdom (UK). The study was a qualitative study. Patients were from SA and ME origins, aged over 18 and prescribed three or more regular medicines. Patients were identified when presenting with a prescription. The data were collected in 80 face-to-face semi-structured interviews using Gordon's MRPs tool. Interviews were audiotaped, transcribed verbatim and analysed thematically using Gordon's coding frame and Nvivo 10 software. Describing MRPs experienced by SA and ME patients from their perspectives and identifying possible contributory factors that may be specific to their cultures. Results Eighty participants (61 % male) had mean (SD) age 58 (13.4) years and a mean (SD) of 8 (4) medicines. Interviews revealed that several factors contributed to the development of MRPs; some appeared to be specific to SA and ME cultures and others were similar to the general population. The factors that were reported to be specific to SA and ME groups comprised religious practices and beliefs, use of non-prescription medicines, extent of family support, and travelling abroad--to patient's homeland or to take religious journeys. Illiteracy, language and communication barriers, lack of translated resources, perceptions of healthcare providers, and difficulty consulting a doctor of the same gender may also contribute to the problems. Many of these factors could be expected to influence patient's safety, adherence, and informed decision-making. This study demonstrated that SA and ME patients have their own problems and needs regarding both medicine use and service access. By uncovering particular problems experienced by these groups, the study can inform healthcare professionals to support SA and ME patients in the use of their medicines.

Patients with vaginitis were classified into four groups: Group A (prepubertal under-aged females); Group B (pubertal under-aged females); Group C (reproductive age adult females); Group D (postmenopausal adult females). All vaginal specimens underwent microscopy, amine testing, Gram staining and culturing. Overall, 163 patients were included (33, 14, 81 and 35 patients, respectively). The most common infection was bacterial vaginosis (BV), followed by Ureaplasma infection, aerobic vaginitis (AV) and candidiasis. The most common AV-associated organism was Escherichia coli and the most common BV-associated organism was Gardnerella vaginalis. AV was more frequent in Group A, BV in Group C and Ureaplasma infections in Groups C/D. Decreased lactobacilli concentrations were associated with BV in fertile patients (Groups B-C). Although presentation of vaginitis is similar among females of different age in Greece, type and prevalence of pathogens differ. Normal vaginal flora changes are associated with higher risk of vaginitis in specific age groups. Impact Statement The worldwide incidence of reproductive tract infections has been increasing, with specific pathogens being associated with significant risk of morbidity and complications. However, literature data on the distribution of such infections in different age groups is limited. Therefore, the aim of this study was to provide data on the prevalence and causes of vaginitis in adult and non-adult females of all ages. This study has shown that although presentation of vaginitis is similar among females of different age groups and menstrual status in Greece, type and prevalence of responsible pathogens are different among groups. Changes in normal vaginal flora seem to be associated with higher risk of vaginitis in specific age-groups as well. These findings could contribute in adjusting diagnostic and therapeutic strategies for each age group according to the prevailing pathogens. Further research on antibiotic resistance and treatment outcomes for each age group should be conducted.

Quantitative Analysis of Swallowing Function Between Dysphagia Patients and Healthy Subjects Using High-Resolution Manometry

2017-01-01

Objective To compare swallowing function between healthy subjects and patients with pharyngeal dysphagia using high resolution manometry (HRM) and to evaluate the usefulness of HRM for detecting pharyngeal dysphagia. Methods Seventy-five patients with dysphagia and 28 healthy subjects were included in this study. Diagnosis of dysphagia was confirmed by a videofluoroscopy. HRM was performed to measure pressure and timing information at the velopharynx (VP), tongue base (TB), and upper esophageal sphincter (UES). HRM parameters were compared between dysphagia and healthy groups. Optimal threshold values of significant HRM parameters for dysphagia were determined. Results VP maximal pressure, TB maximal pressure, UES relaxation duration, and UES resting pressure were lower in the dysphagia group than those in healthy group. UES minimal pressure was higher in dysphagia group than in the healthy group. Receiver operating characteristic (ROC) analyses were conducted to validate optimal threshold values for significant HRM parameters to identify patients with pharyngeal dysphagia. With maximal VP pressure at a threshold value of 144.0 mmHg, dysphagia was identified with 96.4% sensitivity and 74.7% specificity. With maximal TB pressure at a threshold value of 158.0 mmHg, dysphagia was identified with 96.4% sensitivity and 77.3% specificity. At a threshold value of 2.0 mmHg for UES minimal pressure, dysphagia was diagnosed at 74.7% sensitivity and 60.7% specificity. Lastly, UES relaxation duration of <0.58 seconds had 85.7% sensitivity and 65.3% specificity, and UES resting pressure of <75.0 mmHg had 89.3% sensitivity and 90.7% specificity for identifying dysphagia. Conclusion We present evidence that HRM could be a useful evaluation tool for detecting pharyngeal dysphagia. PMID:29201816

Purpose Subcutaneous allergen-specific immunotherapy (SCIT) is a well-established and clinically effective method to treat allergic diseases, such as rhinitis and asthma. It remains unclear how soon after initiation of an ultra-short course of grass pollen immunotherapy adjuvanted with monophosphoryl lipid A (MPL)-specific bronchial tolerance can be induced. Methods In a prospective study of 69 children double-sensitized to birch and grass pollens (51 males, average age 11.1 years), development of bronchial tolerance after 1 cycle of SCIT for grass was evaluated. In all the patients, the bronchial allergen provocation test (BAP) was performed before and after treatment. According to the results of the first BAP, the patients were divided into 2 groups: those showing a negative BAP with a decrease in FEV1 of <20% (seasonal allergic rhinitis [SAR] group, n=47); and those showing a positive BAP with a decrease in FEV1 of ≥20% (SAR with allergic asthma [SAR and Asthma] group, n=22). All the patients received MPL-adjuvanted, ultra-short course immunotherapy for birch, but only those with a positive BAP to grass received MPL-SCIT for grass. Results After the pollen season, the BAP in the SAR group remained unchanged, while it was improved in the SAR and Asthma group (decrease in FEV1 of 28.8% vs 12.5%, P<0.01). The IgG4 levels increased after SCIT (median before SCIT 0.34 to 11.4 after SCIT), whereas the total and specific IgE levels remained unchanged. Conclusions After 1 cycle of MPL-SCIT, specific bronchial tolerance may be significantly induced, whereas in patients without SCIT, bronchial hyperactivity may remain unchanged. PMID:26922936

To compare swallowing function between healthy subjects and patients with pharyngeal dysphagia using high resolution manometry (HRM) and to evaluate the usefulness of HRM for detecting pharyngeal dysphagia. Seventy-five patients with dysphagia and 28 healthy subjects were included in this study. Diagnosis of dysphagia was confirmed by a videofluoroscopy. HRM was performed to measure pressure and timing information at the velopharynx (VP), tongue base (TB), and upper esophageal sphincter (UES). HRM parameters were compared between dysphagia and healthy groups. Optimal threshold values of significant HRM parameters for dysphagia were determined. VP maximal pressure, TB maximal pressure, UES relaxation duration, and UES resting pressure were lower in the dysphagia group than those in healthy group. UES minimal pressure was higher in dysphagia group than in the healthy group. Receiver operating characteristic (ROC) analyses were conducted to validate optimal threshold values for significant HRM parameters to identify patients with pharyngeal dysphagia. With maximal VP pressure at a threshold value of 144.0 mmHg, dysphagia was identified with 96.4% sensitivity and 74.7% specificity. With maximal TB pressure at a threshold value of 158.0 mmHg, dysphagia was identified with 96.4% sensitivity and 77.3% specificity. At a threshold value of 2.0 mmHg for UES minimal pressure, dysphagia was diagnosed at 74.7% sensitivity and 60.7% specificity. Lastly, UES relaxation duration of <0.58 seconds had 85.7% sensitivity and 65.3% specificity, and UES resting pressure of <75.0 mmHg had 89.3% sensitivity and 90.7% specificity for identifying dysphagia. We present evidence that HRM could be a useful evaluation tool for detecting pharyngeal dysphagia.

To study the skin prick test (SPT) reactivity to house dust mite allergens in overweight and normal weight children with allergic asthma before and after standard subcutaneous specific immunotherapy. Two hundred and fifteen children with allergic asthma who had positive SPT responses to Dermatophagoides pteronyssinus (DP) and Dermatophagoides farinae (DF) were enrolled. According to the weight index, they were classified into overweight (n=63) and normal weight groups (n=152). Skin indices (SI) to DP and DF were compared between the two groups at 6 months and 1 year after standard subcutaneous specific immunotherapy. The overweight group had a significantly larger histamine wheal diameter than the normal weight group after controlling the variation in testing time (P<0.05). After controlling the variation in weights, there were significant differences in the SIs to DP and DF before specific immunotherapy and at 6 months and 1 year after specific immunotherapy. At 6 months and 1 year after specific immunotherapy, the SIs to DP and DF were significantly reduced in both groups (P<0.05), and the overweight group had greater decreases in the SIs to DP and DF than the normal weight group. The overweight children with allergic asthma have stronger responses to histamine than the normal weight patients. Specific immunotherapy can reduce the reactivity to dust mite allergens in children with allergic asthma. Within one year after specific immunotherapy, the overweight children with allergic asthma have a significantly greater decrease in the reactivity to dust mite allergens than the normal weight patients.

[Purpose] The objective of this study was to investigate the effects of spinal support device (SSD) on pain and hamstring extensibility in patients with non-specific low back pain (NSLBP). [Subjects and Methods] 20 patients with NSLBP were recruited and randomly assigned to either the SSD group or the control group. In the SSD group, SSD was applied; in the control group, bed rest in supine position was performed. Both groups underwent treatment 20 min/day, 3 times a week, for a duration of 4 weeks. To assess the hamstring extensibility, sit and reach test (SRT) was performed. To assess pain pressure threshold (PPT) of the sacroiliac joint, a pressure algometer was used. Visual analog scale (VAS) was used to quantify pain. [Results] The SSD group showed a significant improvement in sacroiliac joint pain with increased VAS, and the control group showed a significantly increased VAS after intervention. In the SSD group, VAS was significantly increased, but SRT was not changed compared with the control group. [Conclusion] These results demonstrated that an application of SSD effectively attenuates low back pain. Therefore, SSD may be a suitable intervention for pain control in patients with NSLBP.

To analyze the superiority of wait-and-see policy and elective neck dissection in treating cN0 patients with facial cutaneous cell carcinoma (cSCC).Patients with clinically negative parotid and neck metastasis disease were prospectively enrolled. Three groups were divided based on whether the patient received an operation of superficial parotidectomy or/and elective dissection, and regional control and disease-specific survival rates were compared.The occult parotid and neck metastasis rate was 20% and 16%, respectively. There was neck node metastasis without parotid metastasis in only 1 patient. All the node metastasis occurred in level II. Regional recurrence was noted in 16 (16%) patients, and 6 patients died of the disease. In the group undergoing superficial parotidectomy and elective neck dissection, 2 patients had neck node metastasis, and there was no disease-related death, further survival analysis indicated it had better regional control and disease-specific survival rates compared with the other 2 groups.Superficial parotidectomy and elective neck dissection are suggested for patients with T3-4 facial cutaneous squamous cell carcinoma.

In primary health care, efficacious treatment strategies are lacking for these patients, although the most prominent symptoms accounting for consultation in primary care often cannot be related to any biological causes. The aim was to explore whether group supervision from a specific phenomenological theory of psychosomatics could provide healthcare professionals treating patients with psychosomatic health issues within primary care a deeper understanding of these conditions and stimulate profession-specific treatment strategies. Our research questions were as follows: (i) What is the healthcare professionals' understanding of psychosomatics before and after the intervention? (ii) What are the treatment strategies for this group of patients before and after the intervention? The study was an explorative qualitative intervention pilot study. The six participants from a primary healthcare setting in a medium-sized city in Sweden participated in the study. A supervision group was formed, based on a mix of professions, age, gender and years of clinical experience. Supervision consisted of one 75-minutes meeting every month during the course of 6 months. Participants were interviewed before and after the supervision intervention. The study showed two distinct categories emerged from the data. One category of healthcare professionals espoused a psycho-educative approach, while the other lacked a cohesive approach. The supervision improved the second category of healthcare professionals' understanding of psychosomatics. The psycho-educative group did not change their understanding of psychosomatics, although they felt strengthened in their approach by the supervision. Profession-specific strategies were not developed. This pilot study indicates that a relatively short supervision intervention can aid clinicians in their clinical encounters with these patients; however, further research is necessary to ascertain the value of the specific phenomenologically based supervision intervention. © 2017 Nordic College of Caring Science.

Patient-reported outcomes (PROs) have become essential clinical trial end points. However, a comprehensive, multidimensional, patient-relevant, and precise glaucoma-specific PRO instrument is not available. Therefore, the purpose of this study was to identify content for a new, glaucoma-specific, quality-of-life (QOL) item bank. Content identification was undertaken in 5 phases: (1) identification of extant items in glaucoma-specific instruments and the qualitative literature; (2) focus groups and interviews with glaucoma patients; (3) item classification and selection; (4) expert review and revision of items; and (5) cognitive interviews with patients. A total of 737 unique items (extant items from PRO instruments, 247; qualitative articles, 14 items; focus groups and semistructured interviews, 476 items) were identified. These items were classified into 10 QOL domains. Four criteria (item redundancy, item inconsistent with domain definition, item content too narrow to have wider applicability, and item clarity) were used to remove and refine the items. After the cognitive interviews, the final minimally representative item set had a total of 342 unique items belonging to 10 domains: activity limitation (88), mobility (20), visual symptoms (19), ocular surface symptoms (22), general symptoms (15), convenience (39), health concerns (45), emotional well-being (49), social issues (23), and economic issues (22). The systematic content identification process identified 10 QOL domains, which were important to patients with glaucoma. The majority of the items were identified from the patient-specific focus groups and semistructured interviews suggesting that the existing PRO instruments do not adequately address QOL issues relevant to individuals with glaucoma.

Patient navigation is a promising intervention to ameliorate cancer health disparities. This study objective was to measure patient navigation effects on cancer-specific quality of life (QOL) among patients with newly diagnosed cancer. A randomized controlled trial of patient navigation was conducted in Rochester, NY. Patients with breast cancer and colorectal cancer were randomly assigned to receive a patient navigation intervention or usual care. QOL was measured at baseline and four subsequent time points, using the validated Functional Assessment of Cancer Therapy (FACT-B, FACT-C) instruments. Among 319 randomized patients (165 patient navigation, 154 control), median age was 57 years and 32.5% were from minority race/ethnicity groups. Patient navigation and control groups were comparable on baseline factors, except home ownership versus renting (more home ownership among controls, P = 0.05) and race (more whites among controls, P = 0.05). Total and subscale FACT scores did not differ between groups when analyzed as a change from baseline to 3 months, or at various time points. The emotional well-being subscale change from baseline approached significance (better change among patient navigation group, P = 0.05). Time trends of QOL measures did not differ significantly between groups. Adjustment for baseline patient factors did not reveal a benefit of patient navigation on QOL. In this randomized trial of patient navigation, there was no statistically significant effect on disease-specific QOL. These results suggest that patient navigation may not affect QOL during cancer treatment, that social/medical support are adequate in this study's setting, or that the trial failed to target patients likely to experience QOL benefit from patient navigation. 2012 AACR

An association between the survival of patients with oral cavity squamous cell carcinoma (OCSCC) and advancements in diagnosis and therapy has not been established. This was a retrospective, longitudinal, international, population-based study of 2738 patients who underwent resection of OCSCC during 2 different decades. Characteristics of patients from 7 international cancer centers who received treatment between 1990 and 2000 (group A; n = 735) were compared with patients who received treatment between 2001 and 2011 (group B; n = 2003). Patients in group B had more advanced tumors and tended to develop distant metastases more frequently than patients in group A (P = .005). More group B patients underwent selective neck dissection and received adjuvant radiotherapy (P < .001). Outcome analysis revealed a significant improvement in 5-year overall survival, from 59% for group A to 70% for group B (P < .001). There was also a significant improvement in disease-specific survival associated with operations performed before and after 2000 (from 69% to 81%, respectively; P < .001). Surgery after 2000, negative margins, adjuvant treatment, and early stage disease were independent predictors of a better outcome in multivariate analysis. The decade of treatment was an independent prognostic factor for cancer-specific mortality (hazard ratio, 0.42; 95% confidence interval, 0.3-0.6). The survival rate of patients with OCSCC improved significantly during the past 2 decades despite older age, more advanced disease stage, and a higher rate of distant metastases. The current results suggest that the prognosis for patients with OCSCC has improved over time, presumably because of advances in imaging and therapy. © 2013 American Cancer Society.

To estimate the diagnostic accuracy (sensitivity and specificity) of the AdenoPlus point-of-care adenoviral test compared to PCR in an ophthalmic accident and emergency service. These findings were compared with those of a previous study. This was a prospective diagnostic accuracy study on 121 patients presenting to an emergency eye unit with a clinical picture of acute adenoviral conjunctivitis. AdenoPlus testing was carried out on one eye of each patient and a PCR analysis was also performed on a swab taken from the same eye. AdenoPlus and PCR results were interpreted by masked personnel. Sensitivity and specificity for the AdenoPlus test were calculated using PCR results as the reference standard. 121 patients were enrolled and 109 met the inclusion criteria. 43 patients (39.4%) tested positive for adenovirus by PCR analysis. The sensitivity of the AdenoPlus swab in detecting adenovirus was 39.5% (17/43, 95% CI 26% to 54%) and specificity was 95.5% (63/66, 95% CI 87% to 98%) compared to PCR. The AdenoPlus test has a high specificity for diagnosing adenoviral conjunctivitis, but in this clinical setting, we could not reproduce the high sensitivity that has been previously published.

In New Zealand, almost all general practitioners are members of peer groups, which provide opportunities for both clinical discussion and collegial support. This article proposes that peer groups can also be a useful medium for exploring specific challenges within the doctor-patient relationship. However, the peer group culture needs to be receptive to this particular goal. Structured discussion can help peer group members explore interpersonal issues more thoroughly.

To compare the effect of Scientific Exercises Approach to Scoliosis (SEAS) exercises with "usual care" rehabilitation programmes in terms of the avoidance of brace prescription and prevention of curve progression in adolescent idiopathic scoliosis. Prospective controlled cohort observational study. Seventy-four consecutive outpatients with adolescent idiopathic scoliosis, mean 15 degrees (standard deviation 6) Cobb angle, 12.4 (standard deviation 2.2) years old, at risk of bracing who had not been treated previously. Thirty-five patients were included in the SEAS exercises group and 39 in the usual physiotherapy group. The primary outcome included the number of braced patients, Cobb angle and the angle of trunk rotation. There were 6.1% braced patients in the SEAS exercises group vs 25.0% in the usual physiotherapy group. Failures of treatment in the worst-case analysis were 11.5% and 30.8%, respectively. In both cases the differences were statistically significant. Cobb angle improved in the SEAS exercises group, but worsened in the usual physiotherapy group. In the SEAS exercises group, 23.5% of patients improved and 11.8% worsened, while in the usual physiotherapy group 11.1% improved and 13.9% worsened. These data confirm the effectiveness of exercises in patients with scoliosis who are at high risk of progression. Compared with non-adapted exercises, a specific and personalized treatment (SEAS) appears to be more effective.

Patients with medically unexplained symptoms (MUS) are frequent in primary care and substantially impaired in their quality of life (QoL). Specific training of general practitioners (GPs) alone did not demonstrate sustained improvement at later follow-up in current reviews. We evaluated a collaborative group intervention. We conducted a cluster randomized controlled trial. Thirty-five GPs recruited 304 MUS patients (intervention group: 170; control group: 134). All GPs were trained in diagnosis and management of MUS (control condition). Eighteen randomly selected intervention GPs participated in training for a specific collaborative group intervention. They conducted 10 weekly group sessions and 2 booster meetings in their practices, together with a psychosomatic specialist. Six and 12 months after baseline, QoL was assessed with the Short-Form 36. The primary outcome was the physical composite score (PCS), and the secondary outcome was the mental composite score (MCS). At 12 months, intention-to-treat analyses showed a significant between-group effect for the MCS (p = 0.023) but not for the PCS (p = 0.674). This effect was preceded by a significant reduction of somatic symptom severity (15-item somatic symptom severity scale of the Patient Health Questionnaire, PHQ-15) at 6 months (p = 0.008) that lacked significance at 12 months (p = 0.078). As additional between-group effects at 12 months, per-protocol analyses showed less health anxiety (Whiteley-7; p = 0.038) and less psychosocial distress (PHQ; p = 0.024); GP visits were significantly (p = 0.042) reduced in the intervention group. Compared to pure GP training, collaborative group intervention achieved a progressive, clinically meaningful improvement in mental but not physical QoL. It could bridge gaps between general practice and mental health care. Copyright © 2012 S. Karger AG, Basel.

Clinical and neuropsychological correlates of insight in schizophrenia and bipolar I disorder: does diagnosis matter?

Lack of insight is a well-recognized feature of schizophrenia and is associated with symptom severity and cognitive impairments. However, the diagnostic specificity of insight variables and their correlates is not known. To assess this specificity, we compared awareness of illness and neuropsychological function between patients with chronic schizophrenia and bipolar I disorder. We assessed insight, level of psychopathology, and cognitive performance on a neuropsychological test battery in 37 patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition bipolar I disorder, 32 patients with schizophrenia, and 31 healthy subjects for comparison. There was no significant difference between the 2 diagnostic groups on general illness awareness. However, patients with bipolar disorder had better awareness of their symptoms and their pathologic nature compared to patients with schizophrenia. Similar patterns of association emerged between insight and clinical variables. General unawareness was associated with clinical severity, especially of the affective type, and working memory deficits (Wechsler Adult Intelligence Scale digit span) in both diagnostic groups. The contribution of other cognitive deficits to insight differed across the groups. Misattribution differed from the other aspects of insight in its relative independence of clinical and neurocognitive correlates. Both patient groups were neurocognitively impaired, with the schizophrenia group performing significantly worse on conceptual ability, verbal learning, visuospatial processing, and motor speed. The results suggest that differences in general insight in major mental disorders may be explained by symptom severity and working memory function rather than the specific diagnosis. Subcomponents of insight are influenced by different factors emphasizing the need to consider insight as multidimensional.

Background and purpose - Patient-specific instrumentation (PSI) for total knee arthroplasty (TKA) has been introduced to improve alignment and reduce outliers, increase efficiency, and reduce operation time. In order to improve our understanding of the outcomes of patient-specific instrumentation, we conducted a meta-analysis. Patients and methods - We identified randomized and quasi-randomized controlled trials (RCTs) comparing patient-specific and conventional instrumentation in TKA. Weighted mean differences and risk ratios were determined for radiographic accuracy, operation time, hospital stay, blood loss, number of surgical trays required, and patient-reported outcome measures. Results - 21 RCTs involving 1,587 TKAs were included. Patient-specific instrumentation resulted in slightly more accurate hip-knee-ankle axis (0.3°), coronal femoral alignment (0.3°, femoral flexion (0.9°), tibial slope (0.7°), and femoral component rotation (0.5°). The risk ratio of a coronal plane outlier (> 3° deviation of chosen target) for the tibial component was statistically significantly increased in the PSI group (RR =1.64). No significance was found for other radiographic measures. Operation time, blood loss, and transfusion rate were similar. Hospital stay was significantly shortened, by approximately 8 h, and the number of surgical trays used decreased by 4 in the PSI group. Knee Society scores and Oxford knee scores were similar. Interpretation - Patient-specific instrumentation does not result in clinically meaningful improvement in alignment, fewer outliers, or better early patient-reported outcome measures. Efficiency is improved by reducing the number of trays used, but PSI does not reduce operation time.

Elastin fibre detection could be a simple and reliable marker of ventilator associated pneumonia. To confirm this, a prospective study was undertaken to evaluate the diagnostic yield of elastin fibre detection in the diagnosis of ventilator associated pneumonia. Seventy eight mechanically ventilated patients were evaluated by examining endotracheal aspirates for the presence of elastin fibres. All patients were previously treated with antibiotics. Quantitative bacterial cultures of endotracheal aspirates and protected specimen brush samples were also performed. Patients were classified into three diagnostic categories: group 1, definite pneumonia (n = 25); group 2, probable pneumonia (n = 35); and group 3, controls (n = 18). Patients with definite and probable pneumonia were grouped together. The presence of elastin fibres in endotracheal aspirate samples was more frequent in groups 1 and 2, being found in 19 of the 60 patients compared with five of the control group. Although the presence of elastin fibres had a low sensitivity (32%), it was a reasonably specific marker (72%) of pneumonia. This specificity increased to 86% and 81% respectively when only Gram negative bacilli and Pseudomonas aeruginosa pneumonia were considered. Again, calculated sensitivity was 43% and 44% when analysing cases infected by Gram negative bacilli and Ps aeruginosa, respectively. The negative predictive value of the detection of elastin fibres in pneumonia caused by Ps aeruginosa was 81%. Detection was more frequent with infection by Gram negative bacilli (14/19), particularly with Ps aeruginosa (8/14). By contrast, pneumonia due to Gram positive cocci or non-bacterial agents uncommonly resulted in positive elastin fibre preparations (4/19, 21%). When analysing patients with and without chronic obstructive pulmonary disease, the diagnostic value of elastin fibre detection did not change. Potassium hydroxide preparation of elastin fibres is a rapid and simple specific marker of ventilator associated pneumonia and may be a useful technique to help diagnose pulmonary infections in mechanically ventilated patients, although this assessment is at present limited to patients without adult respiratory distress syndrome.

Component resolved allergen diagnosis allows for a precise evaluation of the sensitization profiles of patients sensitized to felines and canines. An accurate interpretation of these results allows better insight into the evolution of a given patients sensitizations, and allows for a more precise evaluation of their prognoses. 70 patients (42 women and 28 men, aged 18-65, with the average of 35.5) with a positive feline or canine allergy diagnosis were included in the research group. 30 patients with a negative allergy diagnosis were included in the control group. The total IgE levels of all patients with allergies as well as their allergen-specific IgE to feline and canine allergens were measured. Specific IgE levels to canine (Can f 1, Can f 2, Can f 3, Can f 5) and feline (Fel d 1, Fel d 2, Fel d 4) allergen components were also measured with the use of the ImmunoCap method. Monosensitization for only one canine or feline component was found in 30% of patients. As predicted, the main feline allergen was Fel d 1, which sensitized as many as 93.9% of patients sensitized to felines. Among 65 patients sensitized to at least one feline component, for 30 patients (46.2%) the only sensitizing feline component was Fel d 1. Only 19 patients in that group (63.3%) were not simultaneously sensitized to dogs and 11 (36.7%), the isolated sensitization to feline Fel d 1 notwithstanding, displayed concurrent sensitizations to one of the canine allergen components. Fel d 4 sensitized 49.2% of the research group.64.3% of patients sensitized to canine components had heightened levels of specific IgE to Can f 1. Monosensitization in that group occurred for 32.1% of the patients. Sensitization to Can f 5 was observed among 52.4% of the patients. Concurrent sensitizations to a few allergic components, not only cross-reactive but also originating in different protein families, are a significant problem for patients sensitized to animals.

We considered group A as 51 patients who also underwent computed-tomography with contrast-enhancement (CECT), and group B as 35 patients who had also been tested for biomarker Ca-125. Sensitivity, specificity, accuracy, positive predictive values (PPV) and negative predictive values (NPV) of (18)F-FDG PET/CT as compared to CECT and to Ca-125 were evaluated. (18)F-FDG PET/CT' sensitivity, specificity, accuracy, PPV and NPV for all 79 patients were: 85%, 92.31%, 88.61%, 91.89% and 85.71%, respectively. (18)F-FDG PET/CT sensitivity in group A was 78.6%, while it was 53.6% for CECT. (18)F-FDG PET/CT specificity, calculated in the same group, was 91.3%, while that of CECT was 60.9% (statistically significant difference, McNemar 4, P=0.039). Accuracy was 84.3% and 56.9%, respectively. (18)F-FDG PET/CT' sensitivity in group B was 86.4%, while that of Ca-125 was 81.8% (no statistical difference, McNemar 0, P=1). (18)F-FDG PET/CT specificity in group B was 84.6% while that of Ca-125 was 38.5% (clear but not statistically significant difference, McNemar 3.12, P=0.070). Accuracy calculated in the same group was 85.7% for (18)F-FDG PET/CT and 65.7% for Ca-125. (18)F-FDG PET/CT is a useful diagnostic tool when peritoneal biopsy cannot be performed and it can better select those who are candidates for adjuvant chemotherapy.

Tham and Tegner proposed the Baking Tray Task (BTT) as a fast simple assessment test for detecting spatial negligence. However, very few studies have examined its validity as a diagnostic test. To analyse the diagnostic validity of the BTT by measuring its specificity and sensitivity in a sample of subjects with right hemisphere strokes. Forty-eight patients with right hemisphere vascular lesions were distributed in two groups (negligence group, n = 35; non-negligence group, n = 13) according to the scores obtained in a battery of visuospatial examination tests. The participants' performance on the BTT was compared with that of a healthy control group (n = 12). The results showed a high level of sensitivity of the BTT, but low specificity. The performance on the BTT of eight of the 13 members of the non-negligence group was suggestive of negligence. The BTT has proved to be a sensitive test for the detection of spatial negligence. Yet, based on its low specificity, its use alone as a single diagnostic test is not recommended.

To describe the perceptions of patients, their caregivers, and their healthcare providers to the development of a new specific instrument for assessment of the quality of life (QoL) in patients with mucopolysaccharidoses (MPS) using a qualitative focus group (FG) design. FGs were held in two Brazilian states (Rio Grande do Sul and Rio de Janeiro). Three versions of the new instrument were developed, each for a different age group: children (age 8-12 years), adolescents (age 13-17), and adults (age ≥ 18). The FGs mostly confirmed the relevance of items. All FGs unanimously agreed on the facets: School, Happiness, Life Prospects, Religiosity, Pain, Continuity of Treatment, Trust in Treatment, Relationship with Family, Relationship with Healthcare Providers, Acceptance, and Meaning of Life. The overall concept of QoL (as proposed by the WHO-World Health Organization) and its facets apply to this patient population. However, other specific facets-particularly concerning clinical manifestations and the reality of the disease-were suggested, confirming the need for the development of a specific QoL instrument for MPS.

Purpose: Extracapsular spread (ECS) in neck lymph nodes is a major adverse prognostic factor in patients with oral cavity squamous cell carcinoma (OSCC). We conducted a retrospective analysis of prognostic factors in this patient group and tried to identify a subset of patients with a worse prognosis suitable for more aggressive therapeutic interventions. Methods and Materials: Enrolled in the study were 255 OSCC patients with ECS in neck nodes and without evidence of distant metastasis. All participants were followed-up for at least 2 years or censored at last follow-up. The 5-year rates of control, distant metastasis, and survival were themore » main outcome measures. Results: Level IV/V lymph node metastases and tumor depth {>=}12 mm were independent predictors of 5-year survival and identified three prognostic groups. In the low-risk group (no level IV/V metastases and tumor depth <12 mm), the 5-year disease-free, disease-specific, and overall survival rates were 60%, 66%, and 50%, respectively. In the intermediate-risk group (no level IV/V metastases and tumor depth {>=}12 mm), the 5-year disease-free, disease-specific, and overall survival rates were 39%, 41%, and 28%, respectively. In the high-risk group (evidence of level IV/V metastases), the 5-year disease-free, disease-specific, and overall survival rates were 14%, 12%, and 10%, respectively. Conclusions: Among OSCC patients with ECS, those with level IV/V metastases appear to have the worst prognosis followed by without level IV/V metastases and tumor depth {>=}12 mm. An aggressive therapeutic approach may be suitable for intermediate- and high-risk patients.« less

During the last years, several approaches were applied on biomedical data to detect disease specific proteins and genes in order to better target drugs. It was shown that statistical and machine learning based methods use mainly clinical data and improve later their results by adding omics data. This work proposes a new method to discriminate the response of Acute Myeloid Leukemia (AML) patients to treatment. The proposed approach uses proteomics data and prior regulatory knowledge in the form of networks to predict cancer treatment outcomes by finding out the different Boolean networks specific to each type of response to drugs. To show its effectiveness we evaluate our method on a dataset from the DREAM 9 challenge. The results are encouraging and demonstrate the benefit of our approach to distinguish patient groups with different response to treatment. In particular each treatment response group is characterized by a predictive model in the form of a signaling Boolean network. This model describes regulatory mechanisms which are specific to each response group. The proteins in this model were selected from the complete dataset by imposing optimization constraints that maximize the difference in the logical response of the Boolean network associated to each group of patients given the omic dataset. This mechanistic and predictive model also allow us to classify new patients data into the two different patient response groups. We propose a new method to detect the most relevant proteins for understanding different patient responses upon treatments in order to better target drugs using a Prior Knowledge Network and proteomics data. The results are interesting and show the effectiveness of our method.

OBJECTIVE: To evaluate the effectiveness of a program to improve hypertension control practices in primary care. DESIGN: Retrospective quasi-experimental study. SETTING: Three hospital-based family medicine centres (FMCs) PARTICIPANTS: Two study groups of 100 randomly-selected adult patients each, who visited the study FMC before implementation of the hypertension program (from April 1, 1983 to March 31, 1984) or afterward (from April 1, 1986 to March 31, 1987). These patients were compared to patients from control FMCs A and B seen during the same time frames (100 patients before and after at FMC A and 60 at FMC B). INTERVENTIONS: 1) Educational sessions for physicians to standardize knowledge of the recommendations of the Canadian Hypertension Society on hypertension treatment and 2) specific operational incentives to improve hypertension control, including a reference guide placed in each physician's office, a specific hypertension follow-up form placed with each patient's chart, a recall card file, and hypertension information handouts. MAIN OUTCOME MEASURE: Blood pressure measurements recorded in patient charts. Hypertension control is determined from the Canadian Hypertension Society recommendations. RESULTS: The hypertension control rate was 52% in the study group before program implementation and 34.3% afterward (p = 0.01); the corresponding rates in the two control groups moved from 47.4% to 59.8% (p > 0.05) in Group A and from 40.7% to 39.3% (p > 0.05) in Group B. Patients listed in the recall card file were not controlled more frequently (33.3%) than those not listed (35.3%). CONCLUSION: This intervention did not improve physician practice regarding hypertension control. Clinicians did not follow the protocol as recommended. Physicians must be convinced that a change in their practice is needed before any specific strategies are introduced to support the change. Different suggestions and alternatives related to hypertension management are discussed. PMID:7950469

Phage idiotype vaccination: first phase I/II clinical trial in patients with multiple myeloma

PubMed Central

2014-01-01

Background Multiple myeloma is characterized by clonal expansion of B cells producing monoclonal immunoglobulins or fragments thereof, which can be detected in the serum and/or urine and are ideal target antigens for patient-specific immunotherapies. Methods Using phage particles as immunological carriers, we employed a novel chemically linked idiotype vaccine in a clinical phase I/II trial including 15 patients with advanced multiple myeloma. Vaccines composed of purified paraproteins linked to phage were manufactured successfully for each patient. Patients received six intradermal immunizations with phage idiotype vaccines in three different dose groups. Results Phage idiotype was well tolerated by all study participants. A subset of patients (80% in the middle dose group) displayed a clinical response indicated by decrease or stabilization of paraprotein levels. Patients exhibiting a clinical response to phage vaccines also raised idiotype-specific immunoglobulins. Induction of a cellular immune response was demonstrated by a cytotoxicity assay and delayed type hypersensitivity tests. Conclusion We present a simple, time- and cost-efficient phage idiotype vaccination strategy, which represents a safe and feasible patient-specific therapy for patients with advanced multiple myeloma and produced promising anti-tumor activity in a subset of patients.

The aim of this study was to evaluate procalcitonin (PCT), C-reactive protein (CRP), platelet count (PLT) and serum lactate dehydrogenase (LDH) as early markers for diagnosis of SIRS, bacterial sepsis and systemic candidiasis in intensive care unit (ICU) patients. Based on blood culture results, the patients were divided into a sepsis group (70 patients), a SIRS group (42 patients) and a systemic candidiasis group (33 patients). PCT, CRP, LDH and PLT levels were measured on day 0 and on day 2 from the sepsis symptom onset. PCT levels were higher in Gram negative sepsis than those in Gram positive sepsis, although the P value between the two subgroups is not significant (P=0.095). Bacterial sepsis group had higher PCT and CRP levels compared with the systemic candidiasis group, whereas PLT and LDH levels showed similar levels in these two subgroups. The AUC for PCT (AUC: 0.892, P <0.001) was larger than for CRP (AUC: 0.738, P <0.001). The best cut-off values for PCT and CRP were 0.99 ng/mL and 76.2 mg/L, respectively. Diagnostic sensitivity and specificity for PCT were 84.3% and 81.8% whereas CRP showed a sensitivity of 77.2% and a specificity of 63.6%. However, PCT was unable to discriminate between SIRS and systemic candidiasis groups (P=0.093 N.S.). In conclusion, PCT can be used as a preliminary marker in the event of clinical suspicion of systemic candidiasis; however, low PCT levels (<0.99 ng/mL) necessarily require the use of other specific markers of candidaemia to confirm the diagnosis, due to great uniformity of PCT levels in systemic candidiasis and SIRS groups.

Strategies for Treating Compensatory Articulation in Patients with Cleft Palate

Del Carmen Pamplona, Maria; Ysunza, Antonio; Morales, Santiago

2014-01-01

Patients with cleft palate frequently show compensatory articulation (CA). CA requires a prolonged period of speech intervention. Some scaffolding strategies can be useful for correcting placement and manner of articulation in these cases. The purpose of this paper was to study whether the use of specific strategies of speech pathology can be more effective if applied according to the level of severity of CA. Ninety patients with CA were studied in two groups. One group was treated using strategies specific for their level of severity of articulation, whereas in the other group all strategies were used indistinctively. The degree of severity of CA was compared at the end of the speech intervention. After the speech therapy intervention, the group of patients in which the strategies were used selectively, showed a significantly greater decrease in the severity of CA, as compared with the patients in whom all the strategies were used indistinctively. An assessment of the severity of CA can be useful for selecting the strategies, which can be more effective for correcting the compensatory errors. PMID:24711749

The basophil activation test (BAT), which relies on flow cytometric quantitation of the allergen-induced up-regulation of the granule-associated marker CD63 in peripheral blood basophils, has been suggested to be a useful approach in detecting responsiveness to allergens. The purpose of this study was to establish the usefulness of the BAT with regard to the clinical history and current diagnostic tools in Hymenoptera venom allergy using a prospective study design. Fifty-seven consecutive patients allergic to Hymenoptera venom as defined by a systemic reaction after an insect sting, and 30 age- and sex-matched control subjects with a negative history were included. The degree and nature of sensitization was confirmed by skin testing, specific immunoglobulin E (IgE), serum tryptase levels and BAT. In the nonallergic control group only analysis of specific IgE and BAT were performed. Correlation of BAT, skin test and specific IgE, respectively, with the clinical history in the allergic group was termed as sensitivity and in the control group as specificity. Twenty one of 23 (91.3%) bee venom allergic patients and 29 of 34 (85.3%) patients allergic to wasp and hornet venom tested positive in BAT. The overall sensitivity of BAT, specific IgE and skin tests were 87.7, 91.2 and 93.0%, respectively. The overall specificities were 86.7% for BAT and 66.7% for specific IgE. No correlation between the severity of clinical symptoms and the magnitude of basophil activation was observed. The BAT seems to be an appropriate method to identify patients allergic to bee or wasp venom with a comparable sensitivity to standard diagnostic regimens. The higher specificity of BAT as compared with specific IgE makes this test a useful tool in the diagnosis of Hymenoptera venom allergy.

Background: Specific cognitive rehabilitation in multiple sclerosis (MS) resulted to be effective compared to no treatment. So far the possible role of an aspecific psychological intervention on cognition has not been investigated. Objective: The aim of the SMICT RCT was to compare the efficacy of a specific cognitive training with an aspecific psychological intervention in relapsing-remitting MS patients. Methods: From a sample of 150 patients, with the same disability and immunomodulatory therapy, submitted to neuropsychological examination, 45 impaired in at least one test were included and 41 randomized to have either a specific cognitive training for the impaired function (22) or to an aspecific psychological intervention (19) for 4 months, starting after baseline examination. Neuropsychological tests and functional scales were administered at baseline and 1 year later. Results: After 1 year, the mean number of pathological tests was significantly lower in the specific treatment group, compared to the aspecific group. Memory and attention/speeded information processing functions were mostly improved. Depression and quality of life were not different between groups at follow up. Conclusion: Our study demonstrates that an intensive and domain specific cognitive approach results to be more effective than aspecific psychological intervention in patients with MS. PMID:25628596

The Global Initiative for Chronic Obstructive Lung Disease (GOLD guideline) for patients with chronic obstructive pulmonary disease does not adequately reflect the impact of the disease because does not take into account daily physical activity (DPA). Forty eight patients (12 in each GOLD group) were prospectively recruited. DPA was evaluated by accelerometer. Patients were classified into 3 levels of activity (very inactive, sedentary, active). No significant differences in levels of physical activity among GOLD groups (P=.361) were observed. The percentages of very inactive patients were 33% in group A, 42% in group B, 42% in group C and 59% in group D. In addition, high percentage of sedentary patients were observed through 4 groups, in group A (50%), B and C (42%, each), and group D (41%). COPD patients has very low levels of physical activity at all stages of GOLD classification even those defined as low impact (such as GOLD A). Is necessary to detect patients at risk who might benefit from specific interventions. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

To investigate the effects of dual-task balance training on postural performance in patients with multiple sclerosis as compared with single-task balance training. Double-blind, pretest-posttest, randomized controlled pilot trial. Local Multiple Sclerosis Society. A total of 47 patients were randomly assigned to two equal groups labeled as single-task training and dual-task training groups. All patients received supervised balance training sessions, 3 times per week for 4 weeks. The patients in the single-task group performed balance activities, alone. However, patients in dual-task group practiced balance activities while simultaneously performing cognitive tasks. The 10-Meter Walk Test and Timed Up-and-Go under single-task and dual-task conditions, in addition to Activities-specific Balance Confidence, Berg Balance Scale, and Functional Gait Assessment were assessed pre-, and post intervention and also 6-weeks after the end of intervention. Only 38 patients completed the treatment plan. There was no difference in the amount of improvement seen between the two study groups. In both groups there was a significant effect of time for dual-10 Meter Walk Test (F 1, 36 =11.33, p=0.002) and dual-Timed Up-and-Go (F 1, 36 =14.27, p=0.001) but not for their single-tasks. Moreover, there was a significant effect of time for Activities-specific Balance Confidence, Berg Balance Scale, and Functional Gait Assessment ( P<0.01). This pilot study did not show more benefits from undertaking dual-task training than single-task training. A power analysis showed 71 patients per group would be needed to determine whether there was a clinically relevant difference for dual-task gait speed between the groups.

Background: Extensive research on both healthy subjects and patients with central nervous damage has elucidated a crucial role of postural adjustment reactions and central sensory integration processes in generating and “shaping” locomotor function, respectively. Whether robotic-assisted gait devices might improve these functions in Multiple sclerosis (MS) patients is not fully investigated in literature. Purpose: The aim of this study was to compare the effectiveness of end-effector robot-assisted gait training (RAGT) and sensory integration balance training (SIBT) in improving walking and balance performance in patients with MS. Methods: Twenty-two patients with MS (EDSS: 1.5–6.5) were randomly assigned to two groups. The RAGT group (n = 12) underwent end-effector system training. The SIBT group (n = 10) underwent specific balance exercises. Each patient received twelve 50-min treatment sessions (2 days/week). A blinded rater evaluated patients before and after treatment as well as 1 month post treatment. Primary outcomes were walking speed and Berg Balance Scale. Secondary outcomes were the Activities-specific Balance Confidence Scale, Sensory Organization Balance Test, Stabilometric Assessment, Fatigue Severity Scale, cadence, step length, single and double support time, Multiple Sclerosis Quality of Life-54. Results: Between groups comparisons showed no significant differences on primary and secondary outcome measures over time. Within group comparisons showed significant improvements in both groups on the Berg Balance Scale (P = 0.001). Changes approaching significance were found on gait speed (P = 0.07) only in the RAGT group. Significant changes in balance task-related domains during standing and walking conditions were found in the SIBT group. Conclusion: Balance disorders in patients with MS may be ameliorated by RAGT and by SIBT. PMID:24904361

During specific immunotherapy (SIT) it is recommended to monitor the patient symptoms in relation to the exposure of allergen which the patient is treated. The aim of the study was to analyze the clinical symptoms of allergic rhinitis (AR) and cross reactivity in patients undergoing specific immunotherapy using pollen allergens (SIT) (birch and/or grasses) against the pollen exposure in 2014-2016. The study group, consisted of patients with pollen allergy, treated by SIT with birch and grasses allergens, who showed oral allergy symptoms. Patients of the control group were sensitive to birch and/or grasses allergens and they were not treated with SIT. The analyses were based on the results of questionnaires and patient symptom diaries. Timing of the pollen seasons of birch and grasses were similar, however the significantly higher concentration of birch pollen was found in 2014 and 2016, comparing to 2015. The strongest relationship between the pollen concentration and symptoms severity was revealed in the study group in patients desensitized by combined vaccine (birch/grasses), while in the control group, in patients sensitive to both taxa. In 35.3% of patients in the study group, a significant decrease in symptoms after foods was found, especially in patients desensitized with mixed vaccine (birch, grasses) after consumption of vegetables and in patients desensitized with grasses allergens after the fruits and nuts. SIT has a significant impact on the symptoms score reduction, which could be modified by the changeable seasonal pollen exposure.

This study examines the relationships between neuroticism (higher-order vulnerability factor), the cognitive styles of worry, brooding and reflection (second-order vulnerability factors) and symptoms of anxiety and depression in three groups of patients: patients with Generalized Anxiety Disorder (GAD), with Major Depressive Disorder (MDD) and with Mixed Anxiety-Depressive Disorder (MADD). One hundred and thirty four patients completed a battery of questionnaires including measures of neuroticism, worry, rumination (brooding and reflection), anxiety and depression. Multiple mediation analyses indicate that worry may act as a mediating mechanism linking neuroticism and anxiety symptoms in the three diagnostic groups, whereas brooding-rumination may play a mediating role between neuroticism and depressive symptoms in patients with MDD and MADD and, with less certainty, in patients with GAD. Overall, our findings suggest that neuroticism may increase the risk of anxious and depressive symptoms via specific links involving either worry or brooding, respectively, and that both worry and brooding may operate in the three groups examined, irrespectively of whether anxiety or depression are the main emotions or whether they coexist without any clear predominance; consequently, we hypothesize the existence of "specific transdiagnostic" mechanisms.

Interpersonal problems are thought to play an essential role in the development and maintenance of eating disorders. The aim of the current study was to investigate whether a specific interpersonal profile could be identified in a group of patients diagnosed with Bulimia Nervosa, Binge Eating Disorder, or Eating Disorders Not Otherwise Specified, and to explore if specific types of interpersonal problems were systematically related to treatment outcome in this group of patients. The participants were 159 patients who received systemic/narrative outpatient group psychotherapy. Interpersonal problems were measured at baseline, and eating disorder symptoms were measured pre- and post treatment. Data were analysed with the Structural Summary Method, a particular method for the analysis of the Inventory of Interpersonal Problems, and hierarchical regression analysis was conducted. The patients demonstrated a generally Non-assertive and Friendly-submissive interpersonal style. No significant association between the overall level of interpersonal problems and treatment outcome was identified. However, the results showed a correlation between being cold and hostile and poor treatment outcome, while being domineering showed a trend approaching significance in predicting better treatment outcome. The results indicate that patients with eating disorders show a specific interpersonal profile, and suggest that particular types of interpersonal problems are associated with treatment outcome.

Patient education is a key component in the management of chronic obstructive pulmonary disease (COPD). Delivering effective education to ethnic groups with COPD is a challenge. The objective of this study was to develop and assess the effectiveness of culturally and linguistically specific audiovisual educational materials in supporting self-management practices in Mandarin- and Cantonese-speaking patients. Educational materials were developed using participatory approach (patients involved in the development and pilot test of educational materials), followed by a randomized controlled trial that assigned 91 patients to three intervention groups with audiovisual educational interventions and one control group (pamphlet). The patients were recruited from outpatient clinics. The primary outcomes were improved inhaler technique and perceived self-efficacy to manage COPD. The secondary outcome was improved patient understanding of pulmonary rehabilitation procedures. Subjects in all three intervention groups, compared with control subjects, demonstrated postintervention improvements in inhaler technique (P<0.001), preparedness to manage a COPD exacerbation (P<0.01), ability to achieve goals in managing COPD (P<0.01), and understanding pulmonary rehabilitation procedures (P<0.05). Culturally appropriate educational interventions designed specifically to meet the needs of Mandarin and Cantonese COPD patients are associated with significantly better understanding of self-management practices. Self-management education led to improved proper use of medications, ability to manage COPD exacerbations, and ability to achieve goals in managing COPD. A relatively simple culturally appropriate disease management education intervention improved inhaler techniques and self-management practices. Further research is needed to assess the effectiveness of self-management education on behavioral change and patient empowerment strategies.

Corticosteroids can cause hypersensitivity reactions, particularly delayed-type allergic reactions. A new classification system for testing hypersensitivity to corticosteroids distributes the drugs into 3 groups according to molecular structure; patients are classified according to whether they are allergic to agents in 1 or more of the groups. We aimed to describe the clinical characteristics of corticosteroid-allergic patients treated at our clinic and apply the new classification system to them; we also compared these patients' characteristics to those of others treated at our clinic. Retrospective study of cases of delayed-type corticosteroid hypersensitivity treated in the skin allergy clinic of a tertiary level hospital over an 11-year period. We reviewed the records of 2857 patients, finding 33 with at least one positive patch test result showing corticosteroid hypersensitivity. Atopic dermatitis and hand involvement were less common in our corticosteroid-allergic patients. All were allergic to a group 1 corticosteroid (most often, budesonide, the culprit in 87.9%). Testing with a specific corticosteroid series revealed that 14 (42.4%) were also allergic to corticosteroids in group 2 and/or group 3. None were allergic exclusively to group 2 or group 3 agents. Twenty-one patients were exposed to a corticosteroid cream from a group their patch test results indicated allergy to; 13 of them (61.9%) did not develop a hypersensitivity reaction. The Spanish standard series only contains group 1 corticosteroids. In the interest of improving allergy management, we recommend testing with a specific corticosteroid series and a patient's own creams whenever patch testing with a standard series reveals a hypersensitivity reaction to corticosteroids.

The present study investigated the application of echocardiography to evaluation of cardiac dyssynchrony in patients with congestive heart failure (CHF). A total of 348 consecutive CHF patients who were admitted for cardiac resynchronization (CRT) and presented with low ejection fraction (EF) and wide QRS duration were enrolled in this study, along with 388 healthy individuals. Dyssynchrony was assessed based on filling time ratio (FT/RR), left ventricular pre-ejection delay (PED), interventricular mechanical delay (IVMD), longitudinal opposing wall delay (LOWD) and radial septal to posterior wall delay (RSPWD). Response to CRT was defined as a ≥15% increase in EF. The results showed that FT/RR was decreased while PED, IVMD, LOWD and RSPWD were increased in the CHF group compared with the control group (P<0.01). In the CHF group, FT/RR was negatively correlated with the QRS duration, LV end-diastolic diameter (LVESd), LV end-diastolic volume (LVEDV) and LV end-systolic volume (LVESV) (P<0.01), but positively with the LVEF (P<0.01). Additionally, PED, IVMD, LOWD and RSPWD were positively correlated with the QRS duration, LVESd, LVEDV and LVESV (P<0.01), but negatively with the LVEF (P<0.01). The CHF group was divided into three subgroups according to the varying degrees of LVEF. FT/RR decreased successively from the LVEF-1 group to the LVEF-2 group to the LVEF-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order (P<0.01). The CHF group was divided into three subgroups according to the varying degrees of QRS duration, and FT/RR decreased successively in a sequence from the QRS-1 group to the QRS-2 group to the QRS-3 group, while the PED, IVMD, LOWD and RSPWD successively increased in the same order (P<0.01). Speckle tracking radial dyssynchrony ≥130 ms was predictive of an EF response in patients in QRS-1 group (78% sensitivity, 83% specificity), those in QRS-2 group (83% sensitivity, 77% specificity) and in QRS-3 group (89% sensitivity, 79% specificity). In conclusion, echocardiography is a convenient and sensitive method for evaluating cardiac dyssynchrony in patients with CHF.

The study presented examines age-specific differences in emotional and behaviour problems as well as resources at the beginning of in-, out- and day-patient youth welfare measures. Additionally, parenting-skills were investigated. A sample of N = 126 was divided by the median (10.1 years) thus leading to two groups: ages six to ten (version for parents) versus eleven to sixteen (self-completion). Children and adolescents were evaluated with the SDQ, parenting skills with the DEAPQ-EL-GS. Values of both groups were compared cross-sectionally with multivariate, one-factorial variance analysis. Parents of younger children achieve significantly better results for parenting-skills. Compared to the older ones, younger children show significantly greater behaviour problems. Younger children belong to the group especially affected in youth welfare measures. Therefore, measures should be specifically adapted for this group to reduce symptoms.

Idiopathic inflammatory myopathies are a group of clinically heterogeneous diseases, which have been classified by myositis specific antibodies recently. The anti-SRP positive subset of this group is characterized by more severe clinical prognosis than other myositis specific antibody positive types. Our goal was to compare 16 anti-SRP positive patients in the Division of Clinical Immunology, Department of Internal Medicine, University of Debrecen with 16 antibody negative ones. Muscle strength validated in both groups by the manual muscle test proved to be significantly decreased both before and after therapy (χ 2 = 0.006 and 0.019) in the anti-SRP positive group. Muscle-specific inflammatory laboratory parameters showed significant difference only in case of LDH-levels after therapy. Both groups showed good clinical response to first line steroid treatment, yet the significantly higher rate of second line administration suggests worse therapeutic response of the antibody positive group. Based on these facts we determined poor clinical prognosis and therapeutic response of the anti-SRP positive group. Orv Hetil. 2017; 158(35): 1382-1389.

Urothelial carcinoma (UC) is a common complication after renal replacement therapy (RRT) among Chinese end-stage renal disease (ESRD) patients. It is unclear whether there are any differences in the clinicopathologic characteristics of UC between renal transplantation (RT) and dialysis patients; such differences could impact RRT modality selection. We retrospectively reviewed clinicopathologic data for 27 RT patients and 40 dialysis patients who were diagnosed with UC in our center to explore differences in the clinicopathologic characteristics of UC and prognoses between the two groups. The median follow-up period was 92 months (2-137) for the RT group and 71 months (18-155) for the dialysis group. The demographic and baseline data showed no significant differences between the two groups. Upper urinary tract UC (UUC) occurred more frequently in the RT group (22 UUCs in 39 UCs), whereas bladder UC (BUC) predominated in the dialysis group (33 BUCs in 49 UCs) (P=0.025). The pathologic grading in the RT group was significantly higher than that in the dialysis group (P=0.046 for WHO1973 grading, P=0.026 for WHO2004 grading), whereas the difference in tumor stage was not significant (P=0.089). The RT group manifested a higher recurrence rate than the dialysis group (P=0.024). However, the overall and cancer-specific survival rates between the two groups were not significantly different (P=0.239 and P=0.818, respectively). Certain traits of UC, including tumor site, pathologic grading, and recurrence-free survival, were notably different between RT and dialysis patients, but the overall and cancer-specific survival rates were similar.

Desensitization regimens including use of intravenous immune globulin and rituximab have been reported to overcome renal transplant hyperacute rejection. A retrospective case-control study was performed to assess the results and complications of renal transplantation with desensitization therapy for donor-specific antibody (DSA) in a transplant center in Asia, where donor exchange was usually not allowed. Between January 2007 and December 2013, 22 patients with DSA received live-donor renal transplantation after desensitization (DSA group). During the same period, the DSA group was compared to the NSA group (152 renal transplants) who had no specific antibody to the donors (66 from deceased donors and 86 from living relatives). Rejection, renal function, graft and patient survival rates, infection, and cancer incidence were reviewed and analyzed from medical records. The DSA group (46.8%) had significantly higher acute rejection rates than the NSA group (13.7%) at the 1-year follow-up. The estimated renal function, 5-year graft, and patient survival rates were comparable between the groups. The DSA group (19.6%) had significantly higher 5-year de novo cancer incidence than the NSA group (8.5%; p = 0.028); three patients of the DSA group developed urothelial carcinoma 17.0 ± 3.0 months after transplantation. By using stepwise Cox regression analysis, desensitization therapy was identified as the sole independent risk factor for post-transplant urothelial carcinoma. When compared to renal transplantation without DSA, desensitization therapy for DSA resulted in equivalent renal transplant outcome but potentially increased risk of urothelial carcinoma after transplantation.

Objectives This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months. Methods Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache. Results Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022–12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036–10,820] in the control group (p<0.0001). The largest cost differences were attributed to productivity losses (homeopathy: EUR 6,289 [6,118–6,460]; control: EUR 5,498 [5,326–5,670], p<0.0001) and outpatient costs (homeopathy: EUR 1,794 [1,770–1,818]; control: EUR 1,438 [1,414–1,462], p<0.0001). Although the costs of the two groups converged over time, cost differences remained over the full 33 months. For all diagnoses, homeopathy patients generated higher costs than control patients. Conclusion The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group. PMID:28915242

To determine the efficacy of Sustained Natural Apophyseal Glides (SNAGs) with and without Isometric Exercise Training Program (IETP) in Non-specific Neck Pain (NSNP) Methods: This randomized control trial of one year duration was conducted at out-patient department of Physiotherapy and Rehabilitation, Khyber Teaching Hospital (KTH) Peshawar, Pakistan from July 2012 to June 2013. The sample of 102 patients of NSNP were randomly selected through simple random sampling technique, and placed into two groups. The SNAGs manual physical therapy technique with IETP was applied on 51 patients in group A and SNAGs manual physical therapy techniques was applied alone on 51 patients in group B. The duration of intervention was 6 weeks, at 4 times per week. The Neck Disability Index (NDI) and Visual Analog Scale (VAS) for neck pain were assessment tools used for all patients before and after 6 weeks of physical therapy intervention. All the patients were assessed through NDI and VAS before intervention and at the completion of 6 weeks program. The data of all 102 was analyzed by SPSS-20 and statistical test was applied at 95% level of significance determine the efficacy of both the treatments interventions and compare with each other. The patients in group A, treated with SNAGs and followed by IETP for 6 weeks, demonstrated more improvement in pain and physical activity as assessed by VAS (p=0.013) and NDI (p=0.003), as compared to the patients treated with SNAGS alone, as pain and function assessed by VAS (p=0.047) and NDI (p=0.164). In group A the NDI score improved from 40 to 15 and VAS from 7 to 4, while in group B the NDI score improved from 42 to 30 and VAS from 7 to 4. Patients with non-specific neck pain treated with SNAGs manual physical therapy techniques and followed by IETP was more effective in reduction of pain and enhancement of function, as compared to those patients treated with SNAGs manual physical therapy techniques alone.

Hyperphosphorylated paratarg-7 (pP-7) is a frequent target of paraproteins in German patients with monoclonal gammopathy of undetermined significance (MGUS)/multiple myeloma (MM). The frequency of MGUS/MM is lower in Japan than in Europe. As pP-7, the first molecularly defined autosomal-dominant risk factor for any hematological neoplasm, is inherited in a dominant fashion, we determined the incidence of the pP-7 carrier state in a Japanese population, and compared the frequency of pP-7-specific paraproteins and the pP-7 carrier state in Japanese and German patients with MGUS/MM. Peripheral blood from 111 Japanese patients with MGUS/MM and 278 healthy blood donors was analyzed for the pP-7 carrier state by isoelectric focusing and for pP-7-specific antibodies by ELISA. The Japanese group was compared with 252 German MGUS/MM patients and 200 healthy controls. Five of 111 (4.5%) Japanese and 35/252 (13.9%) German IgA/IgG MGUS/MM patients had a pP-7-specific paraprotein (P=0.009). The prevalence of healthy pP-7 carriers in the Japanese study group was 1/278 (0.36%), whereas it was 4/200 in the German group (P=0.166). The relative risk for pP-7 carriers developing MGUS/MM had an odds ratio of 13.1 in the Japanese and 7.9 in the German group. In conclusion, the fraction of pP-7 carriers with a pP-7-specific paraprotein is lower among Japanese than in German patients with MGUS/MM, but pP-7 carriers in both ethnic groups have a high risk of developing MGUS/MM. © 2011 Japanese Cancer Association.

To evaluate the clinical benefit of adjuvant platinum-based chemotherapy after radical cystectomy for muscle-invasive bladder cancer in routine clinical practice. The present observational study was carried out to compare the effectiveness of adjuvant chemotherapy versus observation post-radical cystectomy in patients with clinically muscle-invasive bladder cancer. Cancer-specific survival and overall survival between the adjuvant chemotherapy group and radical cystectomy alone group were compared using Kaplan-Meier method and log-rank test. After adjusting for background factors using propensity score weighting, differences in cancer-specific survival and overall survival between these two groups were compared. Subgroup analyses by the pathological characteristics were carried out. In total, 322 patients were included in the present study. Of these, 23% received adjuvant chemotherapy post-radical cystectomy. Clinicopathological characteristics showed that patients in the adjuvant chemotherapy group were pathologically more advanced and were at higher risk than the radical cystectomy alone group. In the unadjusted population, although it is not significant, the adjuvant chemotherapy group had lower overall survival (3-year overall survival; 61.5% vs 73.6%, HR 1.33, P = 0.243, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). In the weighted propensity score analysis, although it is not significant, the adjuvant chemotherapy group were superior to radical cystectomy alone groups (overall survival: HR 0.65, 95% CI 0.39-1.09, P = 0.099, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). Subgroup analyses showed that adjuvant chemotherapy significantly reduced the hazard ratio of overall survival and cancer-specific survival in the ≥pT3, pN+, ly+ and v+ subgroups. Platinum-based adjuvant chemotherapy might be associated with increased cancer-specific survival and overall survival in patients with high-risk invasive bladder cancer. © 2017 The Japanese Urological Association.

To determine the prevalence and clinical association of myositis specific antibodies in an unselected group of patients with juvenile dermatomyositis (DM). The sera of 42 subjects, representing an unselected group of patients from a single center, with juvenile DM and 7 others with idiopathic inflammatory myopathy (IIM) were examined for the presence of myositis specific antibodies by immunodiffusion against calf thymus extract and immunoprecipitation with HeLa extract. Of the subjects with juvenile DM, only 2 had evidence of antibodies specific to myositis (anti-Mi2). Three other patients with juvenile DM had defined autoantibodies not usually considered to be specific to myositis. Two of the 3 subjects had anti-PM-Scl; both developed features of scleroderma after the juvenile DM remitted. The 5 subjects with defined autoantibodies did not differ clinically from the remainder of the subjects with the exception of the late development of scleroderma features in 2. Fourteen other subjects with juvenile DM had unidentified bands on immunoprecipitation, which may represent as yet undiscovered myositis specific antibodies. No myositis specific antibodies were detected in any of the 7 subjects with other IIM syndromes. Based on our findings, we do not recommend routine clinical testing for these antibodies in children with typical juvenile DM. Further study of the unidentified bands seen in our subjects may lead to better understanding of the clinical groupings and etiopathogenesis of childhood myositis.

The aim of this study was to evaluate the efficacy of an intervention combining Life Review Therapy (LRT) and Memory Specificity Training (MST) (LRT-MST) to improve ego-integrity and despair among cancer patients in palliative care. In this multicentre randomized controlled trial, cancer patients in palliative care were randomized to the intervention group (LRT-MST; n = 55) or waiting-list control group (n = 52). LRT-MST is a 4-session home-based psychological intervention that aims to retrieve specific positive memories, to re-evaluate life events and to reconstruct the story of a patient's life, including the diagnosis of incurable cancer. Outcome measures were ego-integrity and despair (NEIS), psychological distress, anxiety and depression (HADS), quality of life (EORTC QLQ-C15-PAL), and specificity of the autobiographical memory (AMT). NEIS, HADS and EORTC QLQ-C15-PAL were assessed at baseline (T0), 1 month later (post-treatment; T1), and at 1 month follow-up (T2). AMT was assessed at T0 and T1. Linear mixed models (intention to treat) were used to assess group differences in changes over time. Independent samples t-tests were used to assess group differences at T0, T1, and T2, and effect sizes (ES) were calculated at T1 and T2. The course of ego-integrity (not despair) improved significantly over time (p = .007) in the intervention group compared to the waiting-list control group, with moderate, but insignificant, effect sizes at T1 (ES = .42) and T2 (ES = .48). Compliance rate was 69% and total dropout rate was 28%, both primarily related to disease progression and death. LRT-MST seems effective among cancer patients in palliative care to improve the course of ego-integrity.

Emotion regulation (ER) difficulties have been considered to play an important role in the development and maintenance of various mental disorders such as depression and anorexia nervosa. However, previous research has failed to provide detailed insight into the disorder-specificity of ER difficulties. Therefore, the present study investigated specific ER difficulties in female samples of patients with major depression, patients with anorexia nervosa, and healthy controls (total sample: N=140). As compared to healthy controls, both clinical groups reported greater ER difficulties concerning both the experience and the differentiation as well as the attenuation and the modulation of emotions. Patients in both clinical groups reported comparably elevated ER difficulties regarding the experience and differentiation of emotions. However, depressed patients reported stronger ER difficulties regarding the attenuation and modulation of emotions as compared to patients with anorexia nervosa. These findings support the notion of ER difficulties as transdiagnostic phenomena, and suggest that depression may be characterized by broader and greater ER difficulties than anorexia nervosa.

Assessing ethical endorsement is crucial to the study of professional performance and moral conduct. There are no specific instruments that verify patients and professional experiences of ethical practice in the specific area of primary health care (PHC). To study the psychometric properties of two questionnaires to identify professional and patient endorsement of normative ethics. A methodological study conducted in PHC centres from an urban area (Barcelona). A group of items from an ethical code were generated using a qualitative study with focus groups. Items underwent expert validation, item refinement and test-retest reliability. Two groups of items for PHC professionals and patients were validated. The structure of the constructs and the internal consistency were studied after participants completed the questionnaires. Principal component analysis with supplementary variables showed the utility of the validated questionnaires. The patients' questionnaire consisted of 17 general items plus 11 additional items on specific conditions, and the health professional's contained 24 general and 9 specific items. The construct of the questionnaires comprised a three-factor solution for patients and a five-factor solution for professionals. Principal component analysis with supplementary variables showed that patients with higher scores on ethical perception were associated with better opinions on health care quality and more confidence in professionals. In PHC professionals, higher scores were associated with effective knowledge of the code. Both questionnaires showed good psychometric properties and are valid to screen ethical attitudes. The instrument warrants further testing and use with culturally diverse patients and PHC professionals.

Background: Pathological complete response (pCR) to neoadjuvant chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC) is still ascribed to a minority of patients. A pathway based-approach could highlight the predictive role of germline single nucleotide polymorphisms (SNPs). The primary aim of this study was to define new predictive biomarkers considering treatment specificities. Secondary aim was to determine new potential predictive biomarkers independent from radiotherapy (RT) dosage and cotreatment with oxaliplatin. Methods: Thirty germ-line SNPs in twenty-one genes were selected according to a pathway-based approach. Genetic analyses were performed on 280 LARC patients who underwent fluoropyrimidine-based CRT. The potential predictive role of these SNPs in determining pathological tumor response was tested in Group 1 (94 patients undergoing also oxaliplatin), Group 2 (73 patients treated with high RT dosage), Group 3 (113 patients treated with standard RT dosage), and in the pooled population (280 patients). Results: Nine new predictive biomarkers were identified in the three groups. The most promising one was rs3136228-MSH6 (p = 0.004) arising from Group 3. In the pooled population, rs1801133-MTHFR showed only a trend (p = 0.073). Conclusion: This exploratory study highlighted new potential predictive biomarkers of neoadjuvant CRT and underlined the importance to strictly define treatment peculiarities in pharmacogenetic analyses.

Chemokines play a key role in inflammatory diseases. The aim of this study was to estimate chemokine RANTES in the sera of patients with atopic dermatitis (AD) and to analyze the correlation between RANTES serum level and the immunological and clinical parameters of the disease. Serum levels of RANTES (ELISA; R&D Systems), total IgE and specific IgE (FEIA; Pharmacia CAP System) were estimated in 24 patients with AD, 28 patients with pollinosis (PL) and 22 healthy nonatopic subjects (HC). The division of the AD group into a pure AD (pAD) subgroup, without a coexisting respiratory allergy, and a subgroup of patients with AD and a respiratory allergy (AD+AO) was done according to Wütrich. Levels of RANTES were higher in the AD group than in the HC group and the PL group. RANTES levels did not differ among subgroups with various clinical scores and between the pAD and AD+AO subgroups. There were no correlations between levels of RANTES and total IgE. Significant positive correlations between serum levels of RANTES and Dermatophagoides farinae and cat dander-specific IgE were found in the AD group. We conclude that the serum level of chemokine RANTES differs patients with AD from patients with PL. The increase of RANTES concentration in the serum of patients with AD depends neither on a clinical picture nor an IgE system.

There is a lack of research investigating models of nursing care for older hospitalised patients that address the nursing needs of this group. The objective of this study is to evaluate the efficacy of models of care for acutely older patients tailored to two contexts: an aged care specific ward and a medical ward. This is a repeated measures design. Efficacy of the models was evaluated in terms of: patient and nurses' satisfaction with care provided; increased activities of daily living; reduced unplanned hospital readmissions; and medication knowledge. An aged care specific ward and a medical ward in two Sydney teaching hospitals. There were two groups of patients aged 65 years or older who were admitted to hospital for an acute illness: those admitted prior to model implementation (n=232) and those admitted during model implementation (n=116). Patients with moderate or severe dementia were excluded. The two groups of nurses were the pre-model group (n=90) who were working on the medical and aged care wards for the study prior to model implementation, and the post-model group (n=22), who were the nurses working on the wards during model implementation. Action research was used to develop the models of care in two wards: one for an aged care specific ward and another for a general medical ward where older patients were admitted. The models developed were based on empirical data gathered in an earlier phase of this study. The models were successful in both wards in terms of increasing satisfaction levels in patients and nurses (p<0.001), increasing functional independence as measured by activities of daily living (p<0.01), and increasing medication knowledge (p<0.001). Findings indicate that models of care developed by nurses using an evidence-based action research strategy can enhance both satisfaction and health outcomes in older patients.

The novel POSEIDON stratification of 'Low prognosis patients in Assisted Reproductive Technology' and its proposed marker of successful outcome.

In reproductive medicine little progress has been achieved regarding the clinical management of patients with a reduced ovarian reserve or poor ovarian response (POR) to stimulation with exogenous gonadotropins -a frustrating experience for clinicians as well as patients. Despite the efforts to optimize the definition of this subgroup of patients, the existing POR criteria unfortunately comprise a heterogeneous population and, importantly, do not offer any recommendations for clinical handling. Recently, the POSEIDON group ( P atient- O riented S trategies E ncompassing I ndividualize D O ocyte N umber) proposed a new stratification of assisted reproductive technology (ART) in patients with a reduced ovarian reserve or unexpected inappropriate ovarian response to exogenous gonadotropins. In brief, four subgroups have been suggested based on quantitative and qualitative parameters, namely, i. Age and the expected aneuploidy rate; ii. Ovarian biomarkers (i.e. antral follicle count [AFC] and anti-Müllerian hormone [AMH]), and iii. Ovarian response - provided a previous stimulation cycle was performed. The new classification introduces a more nuanced picture of the "low prognosis patient" in ART, using clinically relevant criteria to guide the physician to most optimally manage this group of patients. The POSEIDON group also introduced a new measure for successful ART treatment, namely, the ability to retrieve the number of oocytes needed for the specific patient to obtain at least one euploid embryo for transfer. This feature represents a pragmatic endpoint to clinicians and enables the development of prediction models aiming to reduce the time-to-pregnancy (TTP). Consequently, the POSEIDON stratification should not be applied for retrospective analyses having live birth rate (LBR) as endpoint. Such an approach would fail as the attribution of patients to each Poseidon group is related to specific requirements and could only be made prospectively. On the other hand, any prospective approach (i.e. RCT) should be performed separately in each specific group.

Interstitial lung diseases (ILDs) comprise a broad and heterogeneous group of more than two hundred diseases with common functional characteristics. Their diagnosis and management require a multidisciplinary approach. This multidisciplinary approach involves the assessment of comorbid conditions including pulmonary hypertension (PH) that exerts a dramatic impact on survival. The current World Health Organization (WHO) classification of PH encompasses many of the interstitial lung diseases into WHO Group 3, while sarcoidosis, Pulmonary Langerhans Cell Histiocytosis and lymphangioleiomyomatosis are placed into WHO Group 5 as diseases with unclear or multifactorial mechanisms. Connective tissue diseases could span any of the 5 WHO groups based on the primary phenotype into which they manifest. Interestingly, several challenging phenotypes present with features that overlap between two or more WHO PH groups. Currently, PH-specific treatment is recommended only for patients classified into WHO Group 1 PH. The lack of specific treatment for other groups, including PH in the setting of ILD, reflects the poor outcomes of these patients. Thus, identification of the optimal strategy for ILD patients with PH remains an amenable need. This review article provides a brief overview of biomarkers indicative of vascular remodeling in interstitial lung disease, summarizes the current state of knowledge regarding patients with PH and ILD and highlights future perspectives that remain to be addressed.

A strong patient safety culture in the operating room (OR) and post-anesthesia care unit (PACU) is essential to promote safe care. The Patient Safety Climate in Healthcare Organizations (PSCHO) survey was administered to employees at 30 Veterans Affairs (VA) hospitals. The survey consisted of 42 close-ended items representing 12 different dimensions of safety. We measured percent problematic response (PPR); higher PPR values reflect weaker safety culture. The "OR/PACU" and the "Other Work Areas" groups' item-specific, dimension-specific, and overall problematic responses were compared. The overall and dimension-specific PPRs were similar between the OR/PACU and the Other Work Areas group (overall: 20.2% and 18.1%, respectively; P = .41). When the 2 groups were compared on an item-by-item level, the OR/PACU staff reported more frequent witnessing of unsafe patient care (PPR 55.1% vs 43.2%; P = .01), and perceived less understanding by senior leadership of clinical care (PPR 28.3% vs 17.1%; P = .01) and less hospital interest in quality of care (PPR 20.4% vs 12.5%; P = .03). Specific areas of safety culture in the OR/PACU were found that should be targeted for improvement.

Traditional manual instruments for total knee arthroplasty are associated with a malalignment rate of nearly 30%. Patient-specific positioning guides, developed to help address alignment, may also influence other intraoperative factors. This study compared a consecutive series of 270 Vanguard total knee replacements performed with Signature patient-specific positioning guides (study group) to a consecutive series of 595 similar knee replacements performed with manual instrumentation (control group). The study group averaged 16.7 fewer minutes in the operating room (p < .001), utilized tibial inserts that averaged 0.4 mm thinner with a smaller proportion of "thick" tibial inserts (14-18 mm) (p < .001), and required fewer transfusions (p = .022). The Signature-derived surgical plan accurately predicted correct femoral and tibial component sizes in 86.3% and 70.3% of the cases, respectively. These rates increased to 99.3% and 99.2%, respectively, for accuracy to within one size of the surgical plan, similar to published values for manual instrumentation.

Working memory impairments are prevalent among patients with acquired brain injury (ABI). Computerised training targeting working memory has been researched extensively using samples from healthy populations but this field remains isolated from similar research in ABI patients. We report the results of an actively controlled randomised controlled trial in which 17 patients and 18 healthy subjects completed training on an N-back task. The healthy group had superior improvements on both training tasks (SMD = 6.1 and 3.3) whereas the ABI group improved much less (SMD = 0.5 and 1.1). Neither group demonstrated transfer to untrained tasks. We conclude that computerised training facilitates improvement of specific skills rather than high-level cognition in healthy and ABI subjects alike. The acquisition of these specific skills seems to be impaired by brain injury. The most effective use of computer-based cognitive training may be to make the task resemble the targeted behaviour(s) closely in order to exploit the stimulus-specificity of learning.

It is unclear whether risk prediction strategies in chronic heart failure (CHF) need to be specific for sex or beta-blockers. We examined this problem and developed and validated the consequent risk models based on 6-minute-walk-test and NT-proBNP. The derivation cohort comprised 636 German patients with systolic dysfunction. They were validated against 676 British patients with similar aetiology. ROC-curves for 1-year mortality identified cut-off values separately for specificity (none, sex, beta-blocker, both). Patients were grouped according to number of cut-offs met (group I/II/III - 0/1/2 cut-offs). Widest separation between groups was achieved with sex- and beta-blocker-specific cut offs. In the derivation population, 1-year mortality was 0%, 8%, 31% for group I, II and III, respectively. In the validation population, 1-year rates in the three risk groups were 2%, 7%, 14%, respectively, after application of the same cut-offs. Risk stratification for CHF should perhaps take sex and beta-blocker usage into account. We derived and independently validated relevant risk models based on 6-minute-walk-tests and NT-proBNP. Specifying sex and use of beta-blockers identified three distinct sub-groups with widely differing prognosis. In clinical practice, it may be appropriate to tailor the intensity of follow-up and/or the treatment strategy according to the risk-group. Copyright © 2009 Elsevier Ireland Ltd.

Circadian changes of the blood pressure and heart rate in elderly normotensive bedridden patients with severe dementia of the Alzheimer type (group D) were compared with those in elderly normotensive bedridden patients without dementia (group R), normotensive subjects with normal daily activity (group N), and hypertensive patients with normal daily activity (group H). In groups R, N, and H, the blood pressure increased in the afternoon and decreased at midnight; in group D, however, although it increased in the afternoon, it did not decrease at night. The circadian changes of the heart rate were similar in all four groups, showing maxima in the afternoon and minima at midnight. Thus, a specific alteration was found in the circadian rhythm of the blood pressure in patients with Alzheimer-type dementia.

In the TNM seventh edition, a prognostic grouping for prostate cancer incorporating prostate-specific antigen and Gleason score was advocated. The present study was carried out to evaluate and validate prognostic grouping in prostate cancer patients. The 15 259 study patients treated with primary androgen deprivation therapy were enrolled in the Japan Study Group of Prostate Cancer. Overall survival was stratified by tumor-nodes-metastasis, Gleason score and prostate-specific antigen, and extensively analyzed. The accuracy of grouping systems was evaluated by the concordance index. The 5-year overall survival in prognostic grouping-I, IIA, IIB, III and IV was 90.0%, 88.3%, 84.8%, 80.6% and 57.1%, respectively. When considering subgroup stratification, the 5-year overall survival of subgroups prognostic grouping-IIA, IIB, III and IV was 80.9∼90.5%, 75.4∼91.8%, 75.7∼89.0% and 46.9∼86.2%, respectively. When prognostic grouping-IIB was subclassified into IIB1 (except IIB2) and IIB2 (T1-2b, prostate-specific antigen >20, Gleason score ≥8, and T2c, Gleason score ≥8), the 5-year overall survival of IIB2 was significantly lower than that of IIB1 (79.4% and 87.3%, P < 0.0001). Also, when prognostic grouping-IV was subclassified into IV1 (except IV2) and IV2 (M1, prostate-specific antigen >100 or Gleason score ≥8), the 5-year overall survival of prognostic grouping-IV1 was superior to that of IV2 (72.9% and 49.5%, P < 0.0001). Prognostic groupings were reclassified into modified prognostic groupings, divided into modified prognostic grouping-A (prognostic grouping-I, IIA, and IIB1), modified prognostic grouping-B (prognostic grouping-IIB2 and III), modified prognostic grouping-C (prognostic grouping-IV1) and modified prognostic grouping-D (prognostic grouping-IV2). The concordance index of prognostic grouping and modified prognostic grouping for overall survival was 0.670 and 0.685, respectively. Prognostic grouping could stratify the prognosis of prostate cancer patients. However, there is considerable variation among the prognostic grouping subgroups. Thus, the use of a modified prognostic grouping for patients treated with primary androgen deprivation therapy is advisable. © 2013 The Japanese Urological Association.

Delayed onset of neuropsychiatric symptoms after apparent recovery from acute carbon monoxide (CO) poisoning has been described as delayed neuropsychiatric sequelae (DNS). To date, there have been no studies on the utility of serum neuron-specific enolase (NSE), a marker of neuronal cell damage, as a predictive marker of DNS in acute CO poisoning. This retrospective observational study was performed on adult patients with acute CO poisoning consecutively treated over a 9-month period. Serum NSE was measured after emergency department arrival, and patients were divided into two groups. The DNS group comprised patients with delayed sequelae, while the non-DNS group included patients with none of these sequelae. A total of 98 patients with acute CO poisoning were enrolled in this study. DNS developed in eight patients. The median NSE value was significantly higher in the DNS group than in the non-DNS group. There was a statistical difference between the non-DNS group and the DNS group in terms of CO exposure time, Glasgow Coma Scale (GCS), loss of consciousness, creatinine kinase, and troponin I. GCS and NSE were the early predictors of development of DNS. The area under the curve according to the receiver operating characteristic curves of GCS, serum NSE, and GCS combined with serum NSE were 0.922, 0.836, and 0.969, respectively. In conclusion, initial GCS and NSE served as early predictors of development of DNS. Also, NSE might be a useful additional parameter that could improve the prediction accuracy of initial GCS.

There is a need to improve the safety and efficacy of allergen-specific immunotherapy. Long synthetic peptide-based immunotherapy was proven safe, immunogenic, and protective in preclinical trials. To evaluate the safety and immunogenicity of an allergen-derived long synthetic overlapping peptide (LSP) immunotherapy, we designed a double-blind, placebo-controlled phase I clinical trial in patients hypersensitive to bee venom. Patients from the active group were injected at day 0 with a mixture of 3 LSPs mapping the entire PLA2 molecule, a major bee venom allergen, in a dose-escalating protocol to a maintenance dose of 100 microg per peptide repeated at days 4, 7, 14, 42, and 70. The control group was injected with human albumin. Whereas specific T-cell proliferation in the peptide group increased up to day 14, a sharp decline was observed thereafter, ending in specific T-cell hyporesponsiveness at day 80. Serum-specific IgG4 response was enhanced, in contrast to anti-PLA2 IgE. Specific T-cell cytokine modulation was marked by increased IL-10 and IFN-gamma secretion. LSP injections were well tolerated in all patients except for mild, late allergic reactions in 2 patients at day 70. The results of this short-term study demonstrate that LSP-based allergen immunotherapy was safe and able to induce T(H)1-type immune deviation, allergen-specific IL-10 production, and T-cell hyporesponsiveness. LSPs, which offer the advantage of covering all possible T-cell epitopes for any HLA genotype, can be considered candidates for a novel and safe approach of specific immunotherapy.

This paper focuses on the treatment of patients with schizophrenic disorders employing the Team Group model. The advantages and disadvantages of the Team Group are presented. Systems theory and principles of group development are applied as a basis for understanding the dynamics of the group in the context at the acute psychiatric unit. Particular problems encountered in treating patients with schizophrenic disorders in this setting are presented. These include: (1) issues of therapist style and technique, (2) basic psychopathology of the schizophrenic disorders, and (3) phase-specific problems associated with the dynamics of the group. Recommendations for therapist interventions are made that may better integrate these patients into the Team Group.

Purpose: To report our results with accelerated partial breast irradiation (APBI) in terms of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2/neu) status. Methods and Materials: Between February 2003 and June 2009, 209 women with early-stage breast carcinomas were treated with APBI using multicatheter, MammoSite, or Contura brachytherapy to 34 Gy in 10 fractions twice daily over 5-7 days. Three patient groups were defined by receptor status: Group 1: ER or PR (+) and HER-2/neu (-) (n = 180), Group 2: ER and PR (-) and HER-2/neu (+) (n = 10), and Group 3:more » ER, PR, and HER-2/neu (-) (triple negative breast cancer, n = 19). Median follow-up was 22 months. Results: Group 3 patients had significantly higher Scarff-Bloom-Richardson scores (p < 0.001). The 3-year ipsilateral breast tumor control rates for Groups 1, 2, and 3 were 99%, 100%, and 100%, respectively (p = 0.15). Group 3 patients tended to experience relapse in distant sites earlier than did non-Group 3 patients. The 3-year relapse-free survival rates for Groups 1, 2, and 3 were 100%, 100%, and 81%, respectively (p = 0.046). The 3-year cause-specific and overall survival rates for Groups 1, 2, and 3 were 100%, 100%, and 89%, respectively (p = 0.002). Conclusions: Triple negative breast cancer patients typically have high-grade tumors with significantly worse relapse-free, cause-specific, and overall survival. Longer follow-up will help to determine whether these patients also have a higher risk of ipsilateral breast tumor relapse.« less

The purpose of this study was to identify brain atrophy specific for dementia with Lewy bodies (DLB) and to evaluate the discriminatory performance of this specific atrophy between DLB and Alzheimer's disease (AD). We retrospectively reviewed 60 DLB and 30 AD patients who had undergone 3D T1-weighted MRI. We randomly divided the DLB patients into two equal groups (A and B). First, we obtained a target volume of interest (VOI) for DLB-specific atrophy using correlation analysis of the percentage rate of significant whole white matter (WM) atrophy calculated using the Voxel-based Specific Regional Analysis System for Alzheimer's Disease (VSRAD) based on statistical parametric mapping 8 (SPM8) plus diffeomorphic anatomic registration through exponentiated Lie algebra, with segmented WM images in group A. We then evaluated the usefulness of this target VOI for discriminating the remaining 30 DLB patients in group B from the 30 AD patients. Z score values in this target VOI obtained from VSRAD were used as the determinant in receiver operating characteristic (ROC) analysis. Specific target VOIs for DLB were determined in the right-side dominant dorsal midbrain, right-side dominant dorsal pons, and bilateral cerebellum. ROC analysis revealed that the target VOI limited to the midbrain exhibited the highest area under the ROC curves of 0.75. DLB patients showed specific atrophy in the midbrain, pons, and cerebellum. Midbrain atrophy demonstrated the highest power for discriminating DLB and AD. This approach may be useful for determining the contributions of DLB and AD pathologies to the dementia syndrome.

Marital status was found to be an independent prognostic factor for survival in various cancer types, but it hasn't been fully studied in colorectal cancer (CRC). The Surveillance, Epidemiology and End Results database was used to compare survival outcomes with marital status in each stage. In total, 112, 776 eligible patients were identified. Patients in the widowed group were more frequently elderly women, more common of colon cancer, and more stage I/II in tumor stage (P < 0.001), but the surgery rate was comparable to that for the married group (94.72% VS 94.10%). Married CRC patients had better 5year cause-specific survival (CSS) than those unmarried (P < 0.05). Further analysis showed that widowed patients always presented the lowest CSS compared with that of other' group. Widowed patients had 5% reduction 5-year CSS compared with married patients at stage I (94.8% vs 89.8%, P < 0.001), 9.4% reduction at stage II (85.9% vs 76.5%, P < 0.001), 16.7% reduction at stage III (70.6% vs 53.9%, P < 0.001) and 6.2% reduction at stage IV(14.4% VS 8.2%, P < 0.001). These results showed that unmarried patients were at greater risk of cancer specific mortality. Despite favorable clinicpathological characteristics, widowed patients were at highest risk of death compared with other groups.

Background—Early diagnosis of tuberculosis is crucial, especially in Korea, where tuberculosis is endemic. Aims—To evaluate the validity of the ICT tuberculosis test (ICT) in early diagnosis of tuberculosis. Methods—Sixty eight patients with tuberculosis were tested; 37 had no history of previous tuberculosis (patient group 1), and 31 had reactivated tuberculosis (patient group 2). The control groups comprised 77 subjects: 25 healthy adults, 35 hospital workers, and 17 inpatients with non-tuberculous respiratory diseases. Results—The diagnostic sensitivities of ICT were 73% in patient group 1 and 87.1% in patient group 2. In two patients with extrapulmonary tuberculosis, both tested positive using ICT. The specificities of ICT were 88%, 94%, and 94% in healthy adults, hospital workers, and non-tuberculous patients, respectively. Conclusions—ICT is a useful tool for the diagnosis of tuberculosis.

Purpose Clinical features of peanut allergy can range from localized to systemic reactions. Because peanut and birch pollen have cross-reactivity, peanut can lead to localized allergic reaction in Fagales pollen-sensitized oral allergy syndrome (OAS) patients without peanut sensitization per se. The purpose of this study was to discriminate true peanut food allergy from cross-reactive hypersensitivity in birch-sensitized peanut allergy. Methods Birch-sensitized (n=81) and peanut anaphylaxis patients (n=12) were enrolled. Peanut-related allergic reactions and sensitization profiles were examined. Specific IgE to Fagales tree pollens (birch, oak), peanut, and their component allergens (Bet v 1, Bet v 2, Ara h 1, Ara h 2, Ara h 3, Ara h 8, and Ara h 9) were evaluated. Based on these specific IgEs and clinical features, the patients were classified into 4 groups: group 1 (Fagales pollen allergy without OAS), group 2 (Fagales pollen allergy with OAS), group 3 (OAS with peanut anaphylaxis), and group 4 (peanut anaphylaxis). Results After peanut consumption, one-third of OAS patients experienced oral symptoms not associated with peanut sensitization. Ara h 1 or Ara h 2 was positive in peanut anaphylaxis patients, whereas Ara h 8 was positive in OAS patients. There were 4 patients with both peanut anaphylaxis and OAS (group 3). Both Ara h 2 and Ara h 8 were positive in these patients. Foods associated with OAS in Korea showed unique patterns compared to Westernized countries. Conclusions Ara h 2 and Ara h 8 may be important component allergens for discriminating peanut allergy. PMID:27582401

To compare the short-term and medium-term effect of Functional Fascial Taping to placebo taping on pain and function in people with non-specific low back pain. A pilot randomized controlled trial with a 2-week intervention, and 2-, 6- and 12-week follow-up. Individuals with non-specific low back pain recruited from local communities. Forty-three participants with non-specific low back pain for more than 6 weeks were randomized into either Functional Fascial Taping group (n = 21) or placebo group (n = 22). The intervention group was treated with Functional Fascial Taping while the control group was treated with placebo taping. Both groups received four treatments over 2 weeks. Worst and average pain and function were assessed at baseline, after the 2-week intervention, and at 6 and 12 weeks follow-up. The Functional Fascial Taping group demonstrated significantly greater reduction in worst pain compared to placebo group after the 2-week intervention (P = 0.02, effect size = 0.74; 95% confidence interval 0.11-1.34). A higher proportion of participants in Functional Fascial Taping group attained the minimal clinically important difference in worst pain (P = 0.007) and function (P = 0.007) than those in placebo group after the 2-week intervention. There were no significant differences in either group's disability rating or clinically important difference in average pain at any time. Functional Fascial Taping reduced worst pain in patients with non-acute non-specific low back pain during the treatment phase. No medium-term differences in pain or function were observed.

Working Memory and executive functioning deficits are core characteristics of patients suffering from schizophrenia. Electrophysiological research indicates that altered patterns of neural oscillatory mechanisms underpinning executive functioning are associated with the psychiatric disorder. Such brain oscillatory changes have been found in local amplitude differences at gamma and theta frequencies in task-specific cortical areas. Moreover, interregional interactions are also disrupted as signified by decreased phase coherence of fronto-posterior theta activity in schizophrenia patients. However, schizophrenia is not a one-dimensional psychiatric disorder but has various forms and expressions. A common distinction is between positive and negative symptomatology but most patients have both negative and positive symptoms to some extent. Here, we examined three groups-healthy controls, predominantly negative, and predominantly positive symptomatic schizophrenia patients-when performing a working memory task with increasing cognitive demand and increasing need for executive control. We analyzed brain oscillatory activity in the three groups separately and investigated how predominant symptomatology might explain differences in brain oscillatory patterns. Our results indicate that differences in task specific fronto-posterior network activity (i.e., executive control network) expressed by interregional phase synchronization are able to account for working memory dysfunctions between groups. Local changes in the theta and gamma frequency range also show differences between patients and healthy controls, and more importantly, between the two patient groups. We conclude that differences in oscillatory brain activation patterns related to executive processing can be an indicator for positive and negative symptomatology in schizophrenia. Furthermore, changes in cognitive and especially executive functioning in patients are expressed by alterations in a task-specific fronto-posterior connectivity even in the absence of behavioral impairment.

Narratives of empowerment and compliance: studies of communication in online patient support groups.

Wentzer, Helle S; Bygholm, Ann

2013-12-01

New technologies enable new forms of patient participation in health care. The article discusses whether communication in online patient support groups is a source of individual as well as collective empowerment or to be understood within the tradition of compliance. The discussion is based on a qualitative analysis of patient communication in two online groups on the Danish portal sundhed.dk, one for lung patients and one for women with fertility problems. The object of study is the total sum of postings during a specific period of time - a total of 4301 posts are included. The textmaterial was analyzed according to the textual paradigm of Paul Ricoeur, and the three steps of critical interpretation. Thus, the analysis moves from describing communicative characteristics of the site to a thorough semantic analysis of its narrative structure of construing meaning, interaction and collective identity, and finally as a source of collective action. The meta-narratives of the two groups confirm online patient support groups for individual empowerment, for collective group identity, but not for collective empowerment. The collective identities of patienthood on the two sites are created by the users (patients) through specific styles of communication and interaction, referred to as 'multi-logical narratives'. In spite of the potential of online communities of opening up health care to the critical voice of the public, the analysis points to a synthesis of the otherwise opposite positions of empowerment and compliance in patient care. On a collective level, the site is empowering the individual users to comply with 'doctor's recommendations' as a group. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To test effects of a web-based decision support tool, the diabetes Disease Management Application (DMA), developed to improve evidence-based management of type 2 diabetes. We conducted a group randomized controlled trial of 12 intervention and 14 control staff providers and 307 intervention and 291 control patients with type 2 diabetes in a hospital-based internal medicine clinic. Providers were randomly assigned from May 1998 through April 1999 to have access to the DMA (intervention) or not to have access (control). The DMA displays interactive patient-specific clinical data, treatment advice, and links to other web-based care resources. We compared patients in the intervention and control groups for changes in processes and outcomes of care from the year preceding the study through the year of the study by intention-to-treat analysis. The DMA was used for 42% of scheduled patient visits. The number of HbA(1c) tests obtained per year increased significantly in the intervention group (+0.3 tests/year) compared with the control group (-0.04 tests/year, P = 0.008), as did the number of LDL cholesterol tests (intervention, +0.2 tests/year; control, +0.01 tests/year; P = 0.02) and the proportions of patients undergoing at least one foot examination per year (intervention, +9.8%; control, -0.7%; P = 0.003). Levels of HbA(1c) decreased by 0.2 in the intervention group and increased by 0.1 in the control group (P = 0.09); proportions of patients with LDL cholesterol levels <130 mg/dl increased by 20.3% in the intervention group and 10.5% in the control group (P = 0.5). Web-based patient-specific decision support has the potential to improve evidence-based parameters of diabetes care.

Our aim was to identify the optimal diagnostic cutoff point on the scale of protrusion measurements of the first metatarsal (M1) to predict the probability of reulceration after metatarsal head resection in patients with diabetes mellitus. We conducted a prospective study of patients with diabetes who underwent resection of at least 1 metatarsal head in our department. After surgery, we measured the difference in length (protrusion) between the M1 and the longest of the 4 lesser metatarsals by radiographic view. The patients were divided into those in whom the M1 was the longest of the 5 metatarsals (group 1) and patients in whom at least one of the lesser metatarsals was longer than the M1 (group 2). They were followed-up for 12 months and were assessed for reulceration. Ninety-one patients were included in the present study: 43 (47%) in group 1 and 48 (53%) in group 2. In group 1, the longer the protrusion of M1 was, the higher the probability for reulceration (P < .001, 95% confidence interval = 0.813-0.997). In group 2, the shorter the protrusion of M1, the higher the probability for reulceration (P = .002, 95% confidence interval = 0.628-0.905). The optimal cutoff point for group 1 was 11 mm (sensitivity = 84.6%, specificity = 86.7%) for the probability of reulceration. In group 2, it was -7 mm (sensitivity = 81.8%, specificity = 65.4%). These results suggest that M1 protrusion is an optimum prognostic indicator for reulceration and could be recommended for detecting patients at risk of reulceration after surgery.

In this study, we analyzed clinicopathological characteristics and survival outcomes according to extranodal involvement of diffuse large B-cell lymphoma (DLBCL) in the head and neck. A retrospective analysis was conducted on 110 patients from 2004 to 2014 with CD20-positive DLBCL involving the head and neck area. Patients were categorized into two groups, extranodal and nodal, according to involvement of extranodal sites in the head and neck. Outcome measurements for the groups included clinical response to treatment and recurrence rates. Palatine tonsils were the most frequently involved extranodal site in the head and neck (29.1%). Among clinicopathological parameters, proportion of patients with lactate dehydrogenase over 350 IU/L (p=0.033), cell of origin (p<0.001), and treatment outcomes (p=0.007) were significantly different between the two groups. Among cell origin markers CD10, Bcl6, and MUM1, MUM1 was significantly correlated with extranodal involvement (p=0.029). Recurrence rates were similar between groups, while disease-specific survival was significantly higher in the extranodal group (p=0.011). Disease-specific survival of the extranodal group was also higher than the nodal group with extranodal involvement of other body sites (p=0.010). Among patients with negative expression of CD10 (p=0.015), Bcl6 (p=0.018), and MUM1 (p=0.005), survival was longer in the extranodal than the nodal group. DLBCL patients with extranodal involvement of the head and neck may have longer survival outcomes than patients with solely nodal involvement. Increased survival may be more prominent in patients with negative expression of CD10, Bcl6, and MUM1. Copyright © 2018 Elsevier B.V. All rights reserved.

Access to orthodontic services for children enrolled in Medicaid is limited nationwide. Orthodontists cite low fee reimbursement as a significant barrier to Medicaid participation. The purpose of this study was to examine, under a specific set of practice assumptions, the simulated effect on profitability of treating patients covered by Medicaid in orthodontic practices in North Carolina by using a break-even analysis for the 2005 fiscal year. Questionnaires were mailed to 154 orthodontists in active practice in North Carolina. The response rate was 58%. Seventy respondents met the eligibility criteria. Respondents were categorized into 4 groups based on the number of 2005 Medicaid case starts (I, 0; II, 1-5; III, 6-12; IV, 13 or more). By using the aggregated responses for treatment fees, treatment times, and overhead percentages for each group, average per-patient costs were calculated for each group and used in a break-even analysis. Group I accounted for 60% of respondents; group II, 20%; group III, 9%; and group IV, 11%. Assuming that the break-even point had not been reached, the group I practice would have an average estimated loss of $164 per patient whereas groups II, III, and IV would realize average profits from $98 to $256. The break-even point increased slightly in groups I, II, and III after the total number of patients in the patient pool was increased by 5%, assuming that additional patients were enrolled in Medicaid: group I, 203 to 210; group II, 220 to 226; group III, 158 to 160. The break-even point for group IV was 234 patients. Assuming that the break-even point had been reached, all groups were estimated to realize average per-patient profits of $1483 to $1897. Break-even analysis is a basic economic concept applicable to orthodontic practices. Under the specific conditions of this study, the inclusion of 5% of patients enrolled in Medicaid in the active patient pool had minimal effect on the financial break-even point and, assuming that the break-even point had been reached, was unlikely to have a negative financial impact on the practice. 2010 American Association of Orthodontists.

Cystinuria is a rare cause of urolithiasis. Affected patients have an earlier onset and more aggressive disease than patients with other stone etiologies. We assessed the health-related quality of life (HRQOL) of cystine stone-forming patients using the disease-specific Wisconsin Stone Quality of Life questionnaire (WISQOL). Cystine patients treated in our stone clinics (n = 12) completed the WISQOL; information about medical and stone histories was gathered. Patients were matched with noncystine stone formers (n = 12) for gender, age, and comorbidities. In addition, a second control group (n = 90), also from our institution and consisting of mixed calcium stone formers, was included. WISQOL responses were compared between groups. Cystine patients had significantly lower total WISQOL scores than noncystine patients. Compared with noncystine stone formers, cystine stone formers also had lower HRQOL scores for subscales (domains) related to social impact, emotional impact, disease impact, and vitality (p ≤ 0.04 for all). On specific items, cystine patients reported significantly more sleep problems (p = 0.02), more bother with nocturia (p = 0.03), and feeling tired or fatigued (p = 0.02). Among those with current stones, cystine patients scored lower than noncystine patients for total score and in two of four domains. Using a stone-specific questionnaire, patients with cystine stones have lower HRQOL compared with noncystine stone formers. Identifying and addressing specific areas of decrement in patients with cystine stones may improve disease management and patients' HRQOL.

To examine whether an intervention on proper use of electronic medical records (EMRs) in patient care could help improve medical students' empathic engagement, and to test the hypothesis that the training would reduce communication hurdles in clinical encounters. Seventy third-year medical students from the Sidney Kimmel Medical College at Thomas Jefferson University were randomly divided into intervention and control groups during their six-week pediatric clerkship in 2012-2013. The intervention group received a one-hour training session on EMR-specific communication skills, including discussion of EMR use, the SALTED mnemonic and technique (Set-up, Ask, Listen, Type, Exceptions, Documentation), and role-plays. Both groups completed the Jefferson Scale of Empathy (JSE) at the clerkship's start and end. At clerkship's end, faculty and standardized patients (SPs) rated students' empathic engagement in SP encounters, using the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE), and their history-taking and communication skills. Faculty mean ratings on the JSPPPE, history-taking skills, and communication skills were significantly higher for the intervention group than the control group. SP mean ratings on history-taking skills were significantly higher for the intervention group than the control group. Both groups' JSE mean scores increased pretest to posttest, but the changes were not significant. The intervention group's posttest JSE mean score was higher than the control group's, but the difference was not significant. The findings suggest that a simple intervention providing specialized training in EMR-specific communication can improve medical students' empathic engagement in patient care, history-taking skills, and communication skills.

Marital status has been validated as an independent prognostic factor for survival in several cancer types, but is controversial in rectal cancer (RC). The objective of this study was to investigate the impact of marital status on the survival outcomes of patients with RC. We extracted data of 27,498 eligible patients diagnosed with RC between 2004 and 2009 from the Surveillance, Epidemiology and End Results (SEER) database. Patients were categorized into married, never married, divorced/separated and widowed groups.We used Chi-square tests to compare characteristics of patients with different marital status.Rectal cancer specific survival was compared using the Kaplan-Meier method,and multivariate Cox regression analyses was used to analyze the survival outcome risk factors in different marital status. The widowed group had the highest percentage of elderly patients and women,higher proportion of adenocarcinomas, and more stage I/II in tumor stage (P < 0.05),but with a lower rate of surgery compared to the married group (76.7% VS 85.4%). Compared with the married patients, the never married (HR 1.40), widowed (HR 1.61,) and divorced/separated patients (HR 1.16) had an increased overall 5-year mortality. A further analysis showed that widowed patients had an increased overall 5-year cause-specific survival(CSS) compared with married patients at stage I(HR 1.92),stage II (HR 1.65),stage III (HR 1.73),and stage IV (HR 1.38). Our study showed marriage was associated with better outcomes of RC patients, but unmarried RC patients, especially widowed patients,are at greater risk of cancer specific mortality.

To evaluate the effectiveness of isometric exercises as compared to general exercises in chronic non-specific neck pain. For this randomised controlled trial total 68 patients (34 each group) with chronic non-specific neck pain were recruited from Alain Poly Clinic and Institute of Physical Medicine & Rehabilitation Dow University of Health Sciences, Karachi between May, 2012 and August, 2012. Simple randomisation method was used to assign participants into isometric exercise group and general exercise groups. The isometric exercise group performed exercises for neck muscle groups with a rubber band and general exercises group performed active range of movement exercises for all neck movements. Patients in both groups received 3 supervised treatment sessions per week for 12 weeks. Visual Analogue Scale (VAS), North wick Park Neck Pain Questionnaire and goniometer were used to assess pain, disability and neck range of movements at baseline and after 12 weeks. Both interventions showed statistically significant improvements in pain, function and range of movement p = 0.001f or isometric exercise group, p = 0.04 for general exercises group and p = 0.001 for range of movement. However, mean improvements in post intervention VAS score and North wick Park Neck Pain Questionnaire score was better in isometric exercises group as compared to general exercise group. In conclusion, both interventions are effective in the treatment of chronic non-specific neck pain however; isometric exercises are clinically more effective than general exercises.

Skin test sensitivity in patients with immediate allergy to penicillins tends to decrease over time, but no information is available concerning in vitro tests. We analysed the negativization rates of two in vitro methods that determine specific immunoglobulin E (IgE) antibodies, the basophil activation test using flow cytometry (BAT) and the radioallergosorbent test (RAST), in immediate allergic reactions to penicillins. Forty-one patients with immediate allergic reactions to amoxicillin were followed up over a 4-year period. BAT and RAST were performed at 6-month intervals. Patients were randomized into groups: Group I, skin tests carried out at regular intervals; Group II, skin tests made only at the beginning of the study. Differences were observed between RAST and BAT (P < 0.01), the latter showing earlier negativization. Considering different haptens, significant differences for the rate of negativization were only found for amoxicillin (P < 0.05). Comparisons between Groups I (n = 10) and II (n = 31) showed a tendency to become negative later in Group I with RAST. Levels of specific IgE antibodies tended to decrease over time in patients with immediate allergic reactions to amoxicillin. Conversion to negative took longer for the RAST assay, although the differences were only detected with the amoxicillin hapten. Skin testing influenced the rate of negativization of the RAST assay, contributing to maintenance of in vitro sensitivity. Because of the loss of sensitivity over time, the determination of specific IgE antibodies to penicillins in patients with immediate allergic reactions must be done as soon as possible after the reaction.

Bipolar disorder patients experiencing a depressive episode (BD-dep) without an observed history of mania are often misdiagnosed and are consequently treated as having unipolar depression (UD), leading to inadequate treatment and poor outcomes. An essential solution to this problem is to identify objective biological markers that distinguish BD-dep and UD patients at an early stage. However, studies directly comparing the brain dysfunctions associated with BD-dep and UD are rare. More importantly, the specificity of the differences in brain activity between these mental disorders has not been examined. With whole-brain regional homogeneity analysis and region-of-interest (ROI) based receiver operating characteristic (ROC) analysis, we aimed to compare the resting-state brain activity of BD-dep and UD patients. Furthermore, we examined the specific differences and whether these differences were attributed to the brain abnormality caused by BD-dep, UD, or both. Twenty-one bipolar and 21 unipolar depressed patients, as well as 26 healthy subjects matched for gender, age, and educational levels, participated in the study. We compared the differences in the regional homogeneity (ReHo) of the BD-dep and UD groups and further identified their pathophysiological abnormality. In the brain regions showing a difference between the BD-dep and UD groups, we further conducted receptive operation characteristic (ROC) analyses to confirm the effectiveness of the identified difference in classifying the patients. We observed ReHo differences between the BD-dep and UD groups in the right ventrolateral middle frontal gyrus, right dorsal anterior insular, right ventral anterior insular, right cerebellum posterior gyrus, right posterior cingulate cortex, right parahippocampal gyrus, and left cerebellum anterior gyrus. Further ROI comparisons and ROC analysis on these ROIs showed that the right parahippocampal gyrus reflected abnormality specific to the BD-dep group, while the right middle frontal gyrus, the right dorsal anterior insular, the right cerebellum posterior gyrus, and the right posterior cingulate cortex showed abnormality specific to the UD group. We found brain regions showing resting state ReHo differences and examined their sensitivity and specificity, suggesting a potential neuroimaging biomarker to distinguish between BD-dep and UD patients. We further clarified the pathophysiological abnormality of these regions for each of the two patient populations. Copyright © 2012 Elsevier Inc. All rights reserved.

Cervical spinal injuries occur in 2.0-6.6% of patients after blunt trauma and can have devastating neurological sequelae if left unrecognized. Although there is high quality evidence addressing cervical clearance in asymptomatic and symptomatic awake patients, cervical spine clearance in patients with altered level of alertness (i.e., obtunded patients with Glasgow coma scale (GCS) of 14 or less) following blunt trauma has been a matter of great controversy. Furthermore, there are no data on cervical spine clearance in obtunded patients without high impact trauma and these patients are often treated based on evidence from similar patients with high impact trauma. This retrospective study was conducted on this specific subgroup of patients who were admitted to a neurointensive care unit (NICU) with primary diagnoses of intracranial hemorrhage with history of minor trauma; the objective being to evaluate and compare cervical spinal computed tomography (CT) and magnetic resonance imaging (MRI) findings in this particular group of patients. Patients with GCS of 14 or less admitted to neruointensive care unit (NICU) at RUSH University Medical Center from 2008 to 2010 with diagnoses of intracranial hemorrhage (surgical or non-surgical) who had reported or presumed fall (i.e., "found down") were queried from the computer data registry. A group of these patients had cervical spine CT and subsequently MRI for clearing the cervical spine and removal of the cervical collar. Medical records of these patients were reviewed for demographics, GCS score and injury specific data and presence or absence of cervical spine injury. Eighty-three patients were identified from the computer database. Twenty-eight of these patients had positive findings on both CT and MRI (33.73% - Group I); four patients had a negative CT but had positive findings on follow-up MRI (4.82% - Group II); fifty-one patients had both negative CT and MRI (61.44% - Group III). All patients in Group I required either surgical stabilization or continuation of rigid cervical orthosis. All four patients in Group II had intramedullary T2 hyper intensity consistent with possible spinal cord injury on MRI, but did not have any signs of fracture or ligamentous injury to suggest instability. They eventually underwent surgical decompression of the spinal cord during the same hospital stay. Cervical collars were safely removed in all patients in Group III. In our retrospective study, CT had a sensitivity of 0.875 [0.719-0.950, 95% CI] and a specificity of 1.000 [0.930-1.000, 95% CI] in detecting all cervical spine injuries compared to MRI. However, all patients with missed injuries had intramedullary T2 hyper intensity consistent with possible spinal cord injury on MRI and were not unstable precluding cervical spine clearance. If only unstable injuries are considered, CT had a sensitivity of 1.00 [0.879-1.000, 95% CI] and a specificity is 1.000 [0.935-1.000, 95% CI] compared to MRI in this particular group of patients. CT is highly sensitive in detecting unstable injuries in obtunded patients with GCS of 14 or less in the absence of high impact trauma. In the absence of high impact trauma, neurosurgeons should be comfortable to discontinue the cervical collar after a negative, high-quality CT in this patient population. In the presence of focal neurological deficits unexplained by associated intracranial injury, an MRI may help diagnose intrinsic spinal cord injuries which necessarily may not be unstable in the presence of a negative CT and does not precludes clearance of cervical spine.

Background: Bariatric procedures are effective options for weight loss (WL) in the morbidly obese. However, some patients fail to lose any weight after bariatric surgery, and mid-term weight maintenance is variable. The aim of this study was to investigate whether initial WL could predict mid-term weight maintenance. Methods: Eighty patients were enrolled, of whom 44 were treated with the BioEnterics Intragastric Balloon (BIB), 21 with laparoscopic adjustable gastric lap-banding (LAGB), and 15 with laparoscopic sleeve gastrectomy (LSG). Percentage of body WL and percentage of excess weight loss (EWL) were calculated at baseline and after 1, 3, 6, and 12 months. Successful WL was defined as EWL >20% for patients treated with BIB and >50% for patients treated with LAGB and SG. Results: Success in the 6th and 12th month was achieved in 80% and 58% of patients in the BIB group, 33% and 40% in the LAGB group, and 60% and 73% in the LSG group. In the BIB group, WL in the 1st month correlated positively with WL at the 6th and 12th month, and an initial WL >6.5% best predicted success (sensitivity 50%, specificity 80%). A similar association was observed in the LAGB group at the 6th and 12th month and an initial WL >9.4% best predicted success (sensitivity 90.0%, specificity 81.2%). In patients treated with LSG, WL in the 3rd month correlated positively with EWL at the 6th and 12th month, with a cutoff value of 17% (sensitivity 66.7%, specificity 100%). Conclusions: WL in the 1st month in patients treated with BIB and LAGB and WL in the 3rd month in patients treated with LSG could be used as a prognostic factor to predict mid-term weight maintenance.

Blood group B glycosphingolipids (B-GSLs) are substrates of the lysosomal alpha-galactosidase A (AGAL). Similar to its major substrate-globotriaosylceramide (Gb3Cer)-B-GSLs are not degraded and accumulate in the cells of patients affected by an inherited defect of AGAL activity (Fabry disease-FD).The pancreas is a secretory organ known to have high biosynthesis of blood group GSLs. Herein, we provide a comprehensive overview of the biochemical and structural abnormalities in pancreatic tissue from two male FD patients with blood group B. In both patients, we found major accumulation of a variety of complex B-GSLs carrying predominantly hexa- and hepta-saccharide structures. The subcellular pathology was dominated by deposits containing B-glycoconjugates and autofluorescent ceroid. The contribution of Gb3Cer to the storage was minor. This abnormal storage pattern was specific for the pancreatic acinar epithelial cells. Other pancreatic cell types including those of islets of Langerhans were affected much less or not at all.Altogether, we provide evidence for a key role of B-antigens in the biochemical and morphological pathology of the exocrine pancreas in FD patients with blood group B. We believe that our findings will trigger further studies aimed at assessing the potential pancreatic dysfunction in this disease.

To assess the presence of Lepidoglyphus destructor in the household environment of sensitized children living in an urban environment, samples of house dust were collected at the homes where two groups of patients were living, as well as in two bakeries in the city of Valencia, which were taken as a reference. Patients were divided into two groups. Group A included atopic children suffering from rhinitis and/or asthma, who were sensitized to L. destructor, as proven by prick test and specific IgE (CAP). Group B included children with the same features as those included in Group A, who were sensitized to Dermatophagoides pteronyssinus, with prick and CAP tests showing no significant sensitization to L. destructor. The samples of dust were analyzed, and the amounts of Der p I, Der f I, Der II and Lep d I per gram of dust were assessed through a solid-phase ELISA with monoclonal antibodies. In Group A, all patients but two showed a sensitization to D. pteronyssinus by prick test and serum IgE. At the homes of the patients from both groups, significant levels of Dermatophagoides were found. In Group A, only three houses showed levels of L. destructor which were comparable to those found in bakeries. Lep d I was not found in the houses of Group B patients. This means that a sensitization to L. destructor, as assessed with full extracts, is not always an indicator of its presence at the patient's house environment; it may rather refer to cross-reactivity to Dermatophagoides. Thus, availability of the main antigen Lep d I seems necessary to increase the specificity of the allergologic study.

Electromyography (EMG) of the corpora cavernosa (CC-EMG) is able to record the activity of the erectile tissue during erection, and thus has been used as a diagnostic technique in patients with erectile dysfunction (ED). The present study examines the usefulness of the technique in the diagnosis of arterial ED. A cross-sectional study was made of 35 males with a mean age of 48.5 years (s.d. 11.34), referred to our center with ED for >1 year. The patients were subjected to CC-EMG and a penile Doppler ultrasound study following the injection of 20 μg of prostaglandin E1 (PGE1). The patients were divided into three groups according to their response to the intracavernous injection of PGE1: Group 1 (adequate erection and reduction/suppression of EMG activity); Group 2 (insufficient erection and persistence of EMG activity); and Group 3 (insufficient erection and reduction/suppression of EMG activity). Patient classification according to response to the intracavernous injection of PGE1 was as follows: Group 1: six patients (17%), Group 2: 18 patients (51%), and Group 3: 11 patients (31%). Patients diagnosed with arterial insufficiency according to Doppler ultrasound (systolic arterial peak velocity <30 mm s(-1) in both arteries) were significantly older than those without such damage (54.5 versus 41.8 years, respectively; s.d. 11.12). The patients in Group 3 showed a significantly lower maximum systolic velocity in both arteries than the subjects belonging to Group 2. Likewise, a statistically significant relationship was observed between the diagnosis of arterial insufficiency and patient classification in Group 3. The confirmation of insufficient erection associated with reduction/suppression of EMG activity showed a sensitivity of 66.7% (confidence interval between 50 and 84%) and a specificity of 92.9% (confidence interval between 84 and 100%) in the diagnosis of arterial ED. Owing to the high specificity of CC-EMG response to the injection of PGE1, this test is considered useful as a screening technique in the diagnosis of arterial ED.

Patients with Attention-Deficit/Hyperactivity Disorder (ADHD) and obsessive/compulsive disorder (OCD) share problems with sustained attention, and are proposed to share deficits in switching between default mode and task positive networks. The aim of this study was to investigate shared and disorder-specific brain activation abnormalities during sustained attention in the two disorders. Twenty boys with ADHD, 20 boys with OCD and 20 age-matched healthy controls aged between 12 and 18 years completed a functional magnetic resonance imaging (fMRI) version of a parametrically modulated sustained attention task with a progressively increasing sustained attention load. Performance and brain activation were compared between groups. Only ADHD patients were impaired in performance. Group by sustained attention load interaction effects showed that OCD patients had disorder-specific middle anterior cingulate underactivation relative to controls and ADHD patients, while ADHD patients showed disorder-specific underactivation in left dorsolateral prefrontal cortex/dorsal inferior frontal gyrus (IFG). ADHD and OCD patients shared left insula/ventral IFG underactivation and increased activation in posterior default mode network relative to controls, but had disorder-specific overactivation in anterior default mode regions, in dorsal anterior cingulate for ADHD and in anterior ventromedial prefrontal cortex for OCD. In sum, ADHD and OCD patients showed mostly disorder-specific patterns of brain abnormalities in both task positive salience/ventral attention networks with lateral frontal deficits in ADHD and middle ACC deficits in OCD, as well as in their deactivation patterns in medial frontal DMN regions. The findings suggest that attention performance in the two disorders is underpinned by disorder-specific activation patterns.

Although neurological soft signs have been consistently described in patients with schizophrenia, their diagnostic specificity is not well clarified. To test the hypothesis that neurological soft signs are specifically related to schizophrenia, we examined 305 subjects (patients with schizophrenia-spectrum disorder, n=167; patients with bipolar I disorder, n=88; controls, n=50). Neurological soft signs were assessed using the Neurological Evaluation Scale (NES). Multiple logistic regression analysis was used to compute the diagnostic predictive power of neurological soft signs. Patients in the schizophrenia-spectrum disorder group were found to have significantly greater neurological impairment (NES total score=23.9, standard deviation [SD] 11.2) than those in the bipolar disorder group (NES total score=18.2, SD 7.6; p<0.001). Neurological functioning was closely associated with psychopathology (all p<0.001). The NES total score reliably distinguished patients with schizophrenia spectrum disorders from those with bipolar disorder in 68.7% of the cases (p<0.001). Moreover, a particular set of neurological soft signs showed specificity for the schizophrenia-spectrum disorder diagnostic group. Our findings suggest that schizophrenia and bipolar disorder can be distinguished in terms of neurological impairment. Furthermore, we recommend the utility of neurological soft signs as a useful, quantifiable, sensitive, and inexpensive tool for the diagnostic work-up of schizophrenia.

B cell immunity, including the chemokine CXCL13, has an established role in Lyme neuroborreliosis, and also, T helper (Th) 17 immunity, including IL-17A, has recently been implicated. We analysed a set of cytokines and chemokines associated with B cell and Th17 immunity in cerebrospinal fluid and serum from clinically well-characterized patients with definite Lyme neuroborreliosis (group 1, n = 49), defined by both cerebrospinal fluid pleocytosis and Borrelia-specific antibodies in cerebrospinal fluid and from two groups with possible Lyme neuroborreliosis, showing either pleocytosis (group 2, n = 14) or Borrelia-specific antibodies in cerebrospinal fluid (group 3, n = 14). A non-Lyme neuroborreliosis reference group consisted of 88 patients lacking pleocytosis and Borrelia-specific antibodies in serum and cerebrospinal fluid. Cerebrospinal fluid levels of B cell-associated markers (CXCL13, APRIL and BAFF) were significantly elevated in groups 1, 2 and 3 compared with the reference group, except for BAFF, which was not elevated in group 3. Regarding Th17-associated markers (IL-17A, CXCL1 and CCL20), CCL20 in cerebrospinal fluid was significantly elevated in groups 1, 2 and 3 compared with the reference group, while IL-17A and CXCL1 were elevated in group 1. Patients with time of recovery <3 months had lower cerebrospinal fluid levels of IL-17A, APRIL and BAFF compared to patients with recovery >3 months. By using a set of markers in addition to CXCL13 and IL-17A, we confirm that B cell- and Th17-associated immune responses are involved in Lyme neuroborreliosis pathogenesis with different patterns in subgroups. Furthermore, IL-17A, APRIL and BAFF may be associated with time to recovery after treatment.

Paroxysmal nonepileptic events (PNEs) are frequently encountered phenomena in children. Although frequencies and types of PNEs have been extensively studied in adult populations, the data available for children and adolescents are limited, especially in patients without underlying neurologic disorders. In this study, we evaluated and compared the characteristics of PNEs between age groups and according to the presence of neurologic deficits to improve early detection and diagnosis of PNEs. We retrospectively reviewed 887 pediatric patients who were admitted to the epilepsy monitoring unit at the Samsung Medical Center between December 2001 and July 2014. One hundred and forty-one patients (15.9%) were diagnosed as having PNEs on the basis of their clinical history and long-term video-electroencephalography (EEG) monitoring (VEM). Children with PNEs were divided into three groups by age: 1) the infant, toddler, and preschool group (<6 years, N=50, 35.5%); 2) the school-age group (6-<12 years, N=30, 21.3%); and 3) the adolescent group (12-<18 years, N=61, 43.3%). Physiologic disorders, such as normal infant behavior, sleep movement, and staring, were more common in patients younger than 6 years of age, whereas psychogenic nonepileptic seizures were predominant in patients older than 6 years. Vasogenic syncope was also frequently observed in the adolescent group and was confirmed by the head-up tilt test. There was no significant difference in specific PNE types between the groups of patients with or without neurologic deficits. Physiologic symptoms were predominant in the younger age group, whereas psychogenic nonepileptic seizures were observed in older age groups more often. Clinical pattern recognition by age plays an important role in clinical practice, because pediatric patients present various types of PNEs with age-specific patterns. Considering various and inconsistent presentations and the importance of correct diagnosis, long-term VEM can be helpful in diagnosing normal infant behavior and psychogenic nonepileptic seizures.

Conversion disorder is characterized by functional impairment in motor, sensory, or neurovegetative systems that cannot be explained by a general medical condition. Diagnostic systems emphasize the absence of an organic basis for the dysfunction observed in conversion disorder. Nevertheless, there is a growing body of data on the specific functional brain correlates of conversion symptoms, particularly those obtained via neuroimaging and neurophysiological assessment. The present study aimed to determine if there are differences in measures of cognitive functioning between patients with conversion disorder and healthy controls. The hypothesis of the study was that the patients with conversion disorder would have poorer neurocognitive performance than the controls. The patient group included 43 patients diagnosed as conversion disorder and other psychiatric comorbidities according to DSM-IV-TR. Control group 1 included 44 patients diagnosed with similar psychiatric comorbidities, but not conversion diosorder, and control group 2 included 43 healthy individuals. All participants completed a sociodemographic questionnaire and were administered the SCID-I and a neuropsychological test battery of 6 tests, including the Serial Digit Learning Test (SDLT), Auditory Verbal Learning Test (AVLT), Wechsler Memory Scale, Stroop Color Word Interference Test, Benton Judgment of Line Orientation Test (BJLOT), and Cancellation Test. The patient group had significantly poorer performance on the SDLT, AVLT, Stroop Color Word Interference Test, and BJLOT than both control groups. The present findings highlight the differences between the groups in learning and memory, executive and visuospatial functions, and attention, which seemed to be specific to conversion disorder.

Investigators from the University of California, Los Angeles (UCLA), and members of the leadership and data analysis teams at UnitedHealthcare (UHC) are partnering to evaluate the Diabetes Health Plan (DHP), an innovative disease-specific insurance product designed by UHC specifically for patients with prediabetes or diabetes. The DHP provides improved access to care management, telephone coaching, and enhanced Internet-based communication with enrollees. The evaluation will use a quasi-experimental design, comparing patients from employer groups that offer the DHP with patients from groups that do not, to determine the effect of the DHP on incidence of diabetes, adherence to metformin, and costs of care among patients with prediabetes. Other factors studied will be cardiovascular risk factor control, adherence to preventive services, health care use, and costs of care among patients with existing diabetes.

Geriatric stroke patients are generally frail, have an advanced age and co-morbidity. It is yet unclear whether specific groups of patients might benefit differently from structured multidisciplinary rehabilitation programs. Therefore, the aims of our study are 1) to determine relevant patient characteristics to distinguish groups of patients based on their admission scores in skilled nursing facilities (SNFs), and (2) to study the course of these particular patient-groups in relation to their discharge destination. This is a longitudinal, multicenter, observational study. We collected data on patient characteristics, balance, walking ability, arm function, co-morbidity, activities of daily living (ADL), neuropsychiatric symptoms, and depressive complaints of 127 geriatric stroke patients admitted to skilled nursing facilities with specific units for geriatric rehabilitation after stroke. Cluster analyses revealed two groups: cluster 1 included patients in poor condition upon admission (n = 52), and cluster 2 included patients in fair/good condition upon admission (n = 75). Patients in both groups improved in balance, walking abilities, and arm function. Patients in cluster 1 also improved in ADL. Depressive complaints decreased significantly in patients in cluster 1 who were discharged to an independent- or assisted-living situation. Compared to 80% of the patients in cluster 2, a lower proportion (46%) of the patients in cluster 1 were discharged to an independent- or assisted-living situation. Stroke patients referred for rehabilitation to SNFs could be clustered on the basis of their condition upon admission. Although patients in poor condition on admission were more likely to be referred to a facility for long-term care, this was certainly not the case in all patients. Almost half of them could be discharged to an independent or assisted living situation, which implied that also in patients in poor condition on admission, discharge to an independent or assisted living situation was an attainable goal. It is important to put substantial effort into the rehabilitation of patients in poor condition at admission.

Propionibacterium acnes is a clinically relevant pathogen with total shoulder arthroplasty. The purpose of this study was to determine the sensitivity of frozen section histology in identifying patients with Propionibacterium acnes infection during revision total shoulder arthroplasty and investigate various diagnostic thresholds of acute inflammation that may improve frozen section performance. We reviewed the results of forty-five patients who underwent revision total shoulder arthroplasty. Patients were divided into the non-infection group (n = 15), the Propionibacterium acnes infection group (n = 18), and the other infection group (n = 12). Routine preoperative testing was performed and intraoperative tissue culture and frozen section histology were collected for each patient. The histologic diagnosis was determined by one pathologist for each of the four different thresholds. The absolute maximum polymorphonuclear leukocyte concentration was used to construct a receiver operating characteristics curve to determine a new potential optimal threshold. Using the current thresholds for grading frozen section histology, the sensitivity was lower for the Propionibacterium acnes infection group (50%) compared with the other infection group (67%). The specificity of frozen section was 100%. Using a receiver operating characteristics curve, an optimized threshold was found at a total of ten polymorphonuclear leukocytes in five high-power fields (400×). Using this threshold, the sensitivity of frozen section for Propionibacterium acnes was increased to 72%, and the specificity remained at 100%. Using current histopathology grading systems, frozen sections were specific but showed low sensitivity with respect to the Propionibacterium acnes infection. A new threshold value of a total of ten or more polymorphonuclear leukocytes in five high-power fields may increase the sensitivity of frozen section, with minimal impact on specificity.

The aim of this study was to evaluate the results of elective neck dissection compared with observation (control group) in selected cases of early carcinoma of the oral tongue and floor of the mouth. It was a retrospective analysis of 222 patients who had the tumour resected (161 also had elective neck dissection). Occult lymph node metastases were detected in 33/161 (21%), and neck recurrences were diagnosed in 10 of the 61 patients in the control group (16%). Occult lymph node metastases reduced the 5-year disease-specific survival from 90% to 65% (p=0.001) and it was 96% among the controls. The 5-year disease-specific survival was 85% in the group treated by neck dissection and 96% in the observation group (p=0.09). Rigorous follow-up of selected low risk patients is associated with high rates of salvage, and overall survival was similar to the observed survival in patients treated by elective neck dissection. Observation is a reasonable option in the treatment of selected patients. Copyright © 2014 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

Patient-related outcome measures (PROMs) are commonly used to gauge treatment effects in patients with anterior cruciate ligament (ACL) deficiency. Valid measures of specific conditions depend on relevant item content. While item content can be derived either from clinicians (face validity) or from patients, item relevance and comprehensiveness can only be confirmed by the patient (content validity). Focus group and single interviews were conducted with patients' pre- and post-ACL reconstruction in order to construct a condition-specific PROM for the target patients. One hundred fifty-seven items from a previously conducted literature search were used as a basis for content genesis. Content saturation was achieved after three focus groups and seven single interviews. Thirty-eight items from the literature search were directly endorsed, and five modified items were endorsed. Twelve new item themes with verbatim content emerged. Thus, a 55-item pilot PROM consisting of six conceptual domains was assembled. We have constructed a condition-specific PROM for measurement of surgical and non-surgical treatment effects on ACL deficiency. The instrument possesses face and content validity. A pilot survey to assess the psychometric properties will be performed using Rasch measurement theory. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Dysfunctional parenting styles represent a risk factor for the development of psychological disturbances. The present study investigated the differential validity of the German language Fragebogen zur Erfassung dysfunktionaler Erziehungsstile (FDEB; Measurement of Parental Styles, MOPS) and determined whether different forms of psychological disorders are associated with specific patterns of parenting styles. 145 inpatients, 108 outpatients and a control group of 633 representative individuals from the general population were investigated by adapting the FDEB. A comparison of dysfunctional parenting styles showed different distress levels within the diagnostic groups: Patients suffering from depression reported high levels of maternal indifference and over protectiveness together with an abusive rearing behavior on the part of both parents. Patients with anxiety disorders reported having overprotective mothers. Bulimic patients as well as those with personality disorders significantly exhibited stress in almost all areas. However, anorexic patients did not differ significantly from the control group, which appeared to be the least affected of all. The FDEB showed a satisfactory differential validity. There was evidence that specific patterns of dysfunctional parenting styles were associated with different diagnostic groups.

Increased false memory recognition in patients with Huntington's disease (HD) has been widely reported; however, the underlying memory constructive processes remain unclear. The present study explored gist memory, item-specific memory, and monitoring ability in patients with HD. Twenty-five patients (including 13 patients with mild HD and 12 patients with moderate-to-severe HD) and 30 healthy comparison participants (HC) were recruited. We used the Deese-Roediger-McDermott (DRM) paradigm to investigate participants' false recognition patterns, along with neuropsychological tests to assess general cognitive function. Both mild and moderate-to-severe patients with HD showed significant executive functioning and episodic memory impairment. On the DRM tasks, both HD patient groups showed significantly impaired performance in tasks assessing unrelated false recognition and item-specific memory as compared to the HC group; moderate-to-severe patients performed more poorly than mild patients did. Only moderate-severe patients exhibited significantly poorer related false recognition index scores than HCs in the verbal DRM task; performance of HD patient groups was comparable to the HC group on the pictorial DRM task. It appears that diminished verbatim memory and monitoring ability are early signs of cognitive decline during the HD course. Conversely, gist memory is relatively robust, with only partial decline during advanced-stage HD. Our findings suggest that medial temporal lobe function is relatively preserved compared to that of frontal-related structures in early HD. Thus, gist-based memory rehabilitation programs might be beneficial for patients with HD. © The Author 2017. Published by Oxford University Press. All rights reserved.

In this preliminary trial we investigated the effects of dry cupping, an ancient method for treating pain syndromes, on patients with chronic non-specific neck pain. Sensory mechanical thresholds and the participants' self-reported outcome measures of pain and quality of life were evaluated. Fifty patients (50.5 ± 11.9 years) were randomised to a treatment group (TG) or a waiting-list control group (WL). Patients in the TG received a series of 5 cupping treatments over a period of 2 weeks; the control group did not. Self-reported outcome measures before and after the cupping series included the following: Pain at rest (PR) and maximal pain related to movement (PM) on a 100-mm visual analogue scale (VAS), pain diary (PD) data on a 0-10 numeric rating scale (NRS), Neck Disability Index (NDI), and health-related quality of life (SF-36). In addition, the mechanical-detection thresholds (MDT), vibration-detection thresholds (VDT), and pressure-pain thresholds (PPT) were determined at pain-related and control areas. Patients of the TG had significantly less pain after cupping therapy than patients of the WL group (PR: Δ-22.5 mm, p = 0.00002; PM: Δ-17.8 mm, p = 0.01). Pain diaries (PD) revealed that neck pain decreased gradually in the TG patients and that pain reported by the two groups differed significantly after the fifth cupping session (Δ-1.1, p = 0.001). There were also significant differences in the SF-36 subscales for bodily pain (Δ13.8, p = 0.006) and vitality (Δ10.2, p = 0.006). Group differences in PPT were significant at pain-related and control areas (all p < 0.05), but were not significant for MDT or VDT. A series of five dry cupping treatments appeared to be effective in relieving chronic non-specific neck pain. Not only subjective measures improved, but also mechanical pain sensitivity differed significantly between the two groups, suggesting that cupping has an influence on functional pain processing. The trial was registered at clinicaltrials.gov (NCT01289964).

We investigated the association between National Institute of Health category IV prostatitis and prostate-specific antigen levels in patients with low-risk localized prostate cancer. The data of 440 patients who had undergone prostate biopsies due to high PSA levels and suspicious digital rectal examination findings were reviewed retrospectively. The patients were divided into two groups based on the presence of accompanying NIH IV prostatitis. The exclusion criteria were as follows: Gleason score>6, PSA level>20ng/mL, >2 positive cores, >50% cancerous tissue per biopsy, urinary tract infection, urological interventions at least 1 week previously (cystoscopy, urethral catheterization, or similar procedure), history of prostate biopsy, and history of androgen or 5-alpha reductase use. All patient's age, total PSA and free PSA levels, ratio of free to total PSA, PSA density and prostate volume were recorded. In total, 101 patients were included in the study. Histopathological examination revealed only PCa in 78 (77.2%) patients and PCa+NIH IV prostatitis in 23 (22.7%) patients. The median total PSA level was 7.4 (3.5-20.0) ng/mL in the PCa+NIH IV prostatitis group and 6.5 (0.6-20.0) ng/mL in the PCa group (p=0.67). The PSA level was≤10ng/mL in 60 (76.9%) patients in the PCa group and in 16 (69.6%) patients in the PCa+NIH IV prostatitis group (p=0.32). Our study showed no statistically significant difference in PSA levels between patients with and without NIH IV prostatitis accompanying PCa.

Assessment of Digoxin-Specific Fab Fragment Dosages in Digoxin Poisoning.

Digoxin poisoning still remains a common cause of morbidity and mortality. Fortunately, digoxin-specific Fab fragments are commercially available as an antidote. However, these Fab fragments are several thousand dollars per vial. There is a standardized formula to calculate appropriate Fab fragment dosage based on the serum digoxin concentration. This can greatly reduce the amount of Fab fragment administered. There is also an empiric dosing guideline recommending 6-10 vials be given; however, this may result in higher amounts of Fab fragments being administered than required. We performed this study to assess the amounts of digoxin-specific Fab fragments administered in the treatment of digoxin poisonings recorded in a poison control system database from January 1, 2000, to December 31, 2009, in which digoxin serum concentrations were available. This was a retrospective study of 278 patients, 107 with acute poisonings (group A) and 171 following chronic poisoning (group B). In group A, the calculated Fab dose was higher than the calculated dose based on available concentrations in 39 (36%) of group A and 15 (9%) of group B patients. The average wholesale price cost of the excessive dosages ranged from $4818 to as high as $50,589 per patient. Our data suggests that clinician education on digoxin poisoning and the use of the standardized formula to calculate the Fab dose may decrease over utilization and decrease costs associated with the administration of digoxin-specific Fab fragments in the treatment of digoxin poisonings.

The aim of this pilot study was to assess the effect of pre-operative inspiratory muscle training (IMT) on respiratory variables in patients undergoing major abdominal surgery. Respiratory muscle strength (maximum inspiratory [MIP] and expiratory [MEP] mouth pressure) and pulmonary functions were measured at least 2 weeks before surgery in 80 patients awaiting major abdominal surgery. Patients were then allocated randomly to one of four groups (Group A, control; Group B, deep breathing exercises; Group C, incentive spirometry; Group D, specific IMT). Patients in groups B, C and D were asked to train twice daily, each session lasting 15 min, for at least 2 weeks up to the day before surgery. Outcome measurements were made immediately pre-operatively and postoperatively. In groups A, B and C, MIP did not increase from baseline to pre-operative assessments. In group D, MIP increased from 51.5 cmH(2)O (median) pre-training to 68.5 cmH(2)O (median) post-training pre-operatively (P < 0.01). Postoperatively, groups A, B and C showed a fall in MIP from baseline (P < 0.01, P < 0.01) and P = 0.06, respectively). No such significant reduction in postoperative MIP was seen in group D (P = 0.36). Pre-operative specific IMT improves MIP pre-operatively and preserves it postoperatively. Further studies are required to establish if this is associated with reduced pulmonary complications.

Aim: The purpose of this study was to investigate continuity of care in the psychiatric healthcare system from the perspective of patients, including vulnerable groups such as immigrants and refugees. Method: The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes). Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Results: Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. Conclusions: The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups. PMID:25233017

This study evaluated the use of polymerase chain reaction for cryptococcal meningitis diagnosis in clinical samples. The sensitivity and specificity of the methodology were evaluated using eight Cryptococcus neoformans/C. gattii species complex reference strains and 165 cerebrospinal fluid samples from patients with neurological diseases divided into two groups: 96 patients with cryptococcal meningitis and AIDS; and 69 patients with other neurological opportunistic diseases (CRL/AIDS). Two primer sets were tested (CN4-CN5 and the multiplex CNa70S-CNa70A/CNb49S-CNb-49A that amplify a specific product for C. neoformans and another for C. gattii). CN4-CN5 primer set was positive in all Cryptococcus standard strains and in 94.8% in DNA samples from cryptococcal meningitis and AIDS group. With the multiplex, no 448-bp product of C. gattii was observed in the clinical samples of either group. The 695bp products of C. neoformans were observed only in 64.6% of the cryptococcal meningitis and AIDS group. This primer set was negative for two standard strains. The specificity based on the negative samples from the CTL/AIDS group was 98.5% in both primer sets. These data suggest that the CN4/CN5 primer set was highly sensitive for the identification of C. neoformans/C. gattii species complex in cerebrospinal fluid samples from patients with clinical suspicion of cryptococcal meningitis.

Gait characteristics and balance are altered in diabetic patients. Little is known about possible treatment strategies. This study evaluates the effect of a specific training programme on gait and balance of diabetic patients. This was a randomised controlled trial (n=71) with an intervention (n=35) and control group (n=36). The intervention consisted of physiotherapeutic group training including gait and balance exercises with function-orientated strengthening (twice weekly over 12 weeks). Controls received no treatment. Individuals were allocated to the groups in a central office. Gait, balance, fear of falls, muscle strength and joint mobility were measured at baseline, after intervention and at 6-month follow-up. The trial is closed to recruitment and follow-up. After training, the intervention group increased habitual walking speed by 0.149 m/s (p<0.001) compared with the control group. Patients in the intervention group also significantly improved their balance (time to walk over a beam, balance index recorded on Biodex balance system), their performance-oriented mobility, their degree of concern about falling, their hip and ankle plantar flexor strength, and their hip flexion mobility compared with the control group. After 6 months, all these variables remained significant except for the Biodex sway index and ankle plantar flexor strength. Two patients developed pain in their Achilles tendon: the progression for two related exercises was slowed down. Specific training can improve gait speed, balance, muscle strength and joint mobility in diabetic patients. Further studies are needed to explore the influence of these improvements on the number of reported falls, patients' physical activity levels and quality of life.

The aim of this study was to examine early signs of psychosis in patients suffering from both drug dependence and schizophrenia, compared to a control group of drug-addicted patients without a comorbid psychotic disorder, and to assess whether the presence of these signs was related to changes in the pattern of substance abuse. In a rehabilitation hospital for young addicts, 32 patients with a comorbid diagnosis of schizophrenia and 30 patients without the diagnosis of a psychotic disorder, were assessed using the Interview for the Retrospective Assessment of the Onset of Schizophrenia. Information relating to 64 signs of early psychosis was collected from every patient. From the 64 signs, five groups of symptoms were defined: non-specific and precursor symptoms; non-specific and depressive symptoms; negative symptoms; positive symptoms; and impaired social adjustment. The semiquantitative pattern of substance abuse for each 1-year interval over the previous 10 years was investigated using the categories of chapter F1 of ICD-10 and including an additional category "biological drugs". The relationship between the pattern of substance abuse and the presence of early signs was assessed using anova and non-parametric statistical methods. The results indicate that the defined pathological symptomatology greatly influences the pattern of consumption of psychoactive substances in both the psychosis group and the control group. The group factor exerted the greatest influence within the categories "biological drugs" and "other stimulants", where the "psychosis and addiction group" consumed significantly more than the control group. There is a subgroup of non-psychotic addicted patients whose pattern of psychoactive substance abuse is similar to that found in addicted patients suffering from schizophrenia. It may be helpful to systematically identify this subgroup with regard to possible therapeutic implications, particularly with regard to possible pharmacological treatment options.

Acute-on-chronic liver failure (ACLF) is characterized by a rapid progression to multiple organ failure and is associated with a very high mortality rate of 50-90%. Novel therapies are being investigated such as Erythropoietin (EPO). The aim of this prospective cohort study was to analyse the value of EPO in predicting prognosis and determine which patients may benefit most from EPO therapy. According to the EASL-CLIF criteria, 104 consecutive patients were diagnosed with ACLF, and separated into two groups based on the type of insult: bleeding (Group A=31) or non-bleeding (Group B=73). In addition to a complete biochemical work-up and calculation of relevant prognostic scores, levels of EPO were measured on admission and correlated to the type of insult and final outcome. Fifteen patients from Group A (mean age 60.32+/-9.29 years) had a lethal outcome and higher values of EPO on admission (319.26+/-326.58 mIU/ml) (p<0.005), compared to the 37 patients from Group B (mean age 59.9+/-10.19 years) with EPO levels at admission of 29.88+/-34.6 mIU/mL. In Group B, a cut-off EPO value of 30.65 mIU/mL had a sensitivity of 87.5% and a specificity 57.4% in predicting lethal outcome with an AUROC of 0.823. In Group A, a cut-off value of 229.95 mlU/mL had a sensitivity and specificity of 53.3% and 92.7%, respectively. The AUROC for this cut-off was 0.847. Erythropoietin is superior to the standard prognostic scores in predicting 28-day mortality. Lower levels of EPO were detected in patients without bleeding as an insult indicating a possible therapeutic benefit in these patients.

To investigate beliefs about medicines and their association with medicine adherence in patients with chronic diseases in China. A cross-sectional questionnaire-based study SETTING: Two large urban hospitals in Hefei and Tianjin, China PARTICIPANTS: Hospital inpatients (313 stroke patients) and outpatients (315 diabetic patients and 339 rheumatoid arthritis (RA) patients) were recruited between January 2014 and September 2014. The Beliefs about Medicines Questionnaire (BMQ), assessing patients' beliefs about the specific medicine (Specific-Necessity and Specific-Concerns) prescribed for their conditions (stroke/diabetes/RA) and more general background beliefs about pharmaceuticals as a class of treatment (BMQ-General Benefit, Harm and Overuse); the Perceived Sensitivity to Medicines scale (PSM) assessed patients' beliefs about how sensitive they were to the effects of medicines and the Medication Adherence Report Scale. The association between non-adherence and beliefs about medicines was assessed using a logistic regression model. Patients with diabetes mellitus had a stronger perceived need for treatment (mean (SD) Specific-Necessity score, 3.75 (0.40)) than patients with stroke (3.69 (0.53)) and RA (3.66 (0.44)) (p=0.049). Moderate correlations were observed between Specific-Concerns and General-Overuse, General-Harm and PSM (Pearson correlation coefficients, 0.39, 0.49 and 0.49, respectively, p<0.01). Three hundred and eleven patients were non-adherent to their medicine (159 (51.0%) in the stroke group, 60 (26.7%) in the diabetes mellitus group and 62 (19.8%) in the RA group, p<0.01). Across the whole sample, after adjusting for demographic characteristics, non-adherence was associated with patients who had higher concerns about their medicines (OR, 1.35, 95% CI 1.07 to 1.71) and patients who believed that they were personally sensitive to the effects of medications (OR 1.44, 95% CI 1.16 to 1.85). The BMQ is a useful tool to identify patients at risk of non-adherence. In the future, adherence intervention studies may use the BMQ to screen for patients who are at risk of non-adherence and to map interventional support. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Although specific nasal provocation is an objective diagnostic test for allergic rhinitis, it can also increase the lower airway responsiveness in asthmatic patients. Our goal was to determine the value and safety of specific nasal provocation test for the diagnosis of allergic rhinitis in mild persistent asthmatic patients under low-dose inhaled steroid therapy. The study was performed on 32 mild persistent, stable, mite-sensitive allergic asthmatics (group 1), 9 mild persistent nonallergic asthmatics (group 2) and 9 healthy non-smokers (group 3). Nasal symptoms were noted, paranasal sinus computerized tomography (PNCT) and rhinoscopic evaluations were performed. Cases with pathologic-anatomic changes in PNCT and rhinoscopy were excluded. Symptom scoring, flow-volume, peak expiratory flow (PEF), serum and nasal lavage eosinophil cationic protein (ECP) and nasal lavage eosinophil counts were performed before mite specific nasal provocation test and at the 0th, 4th and 24th hours following the test. No adverse effects were observed in all diagnostic procedures. Total diagnostic value of nasal symptoms were found to be at 92%, while being 70% for rhinoscopy and 88% for specific nasal provocation test respectively in the diagnosis of allergic rhinitis in group 1. Statistically significant differences were found between basal nasal lavage eosinophil values (p < 0.001) and ECP levels (p < 0.05) when group 1 was compared with both group 2 and group 3. In the remaining measured values between three groups, no statistically significant differences were found. Specific nasal provocation test is a safe method for mild house dust mite allergic asthma cases under low-dose inhaled steroid therapy, but history of rhinitis might be sufficient for the diagnosis of allergic rhinitis.

The purpose of this study was to determine the specificity of the LV/RV for mitral insufficiency. One hundred and sixty patients underwent MUGA studies as part of their diagnostic evaluation. Phase analysis was performed. In the amplitude image, the LV/RV was measured. Patients were divided into 11 clinical groups based on chart review after adequate follow-up. The groups were compared by Duncan's Multiple Comparsion Test. Patients with mitral insufficiency (N = 12, mean LV/RV = 2.36), those with idiopathic myocardiopathy (8, 2.29) and those with normal hearts having lung disease on chest x-ray (22, 1.78) formed a group which atmore » the p < .05 level were not different from one another. Patients with idiopathic myocardiography, normal hearts with lung disease on chest x-ray, normal hearts with lung disease (23, 1.71) formed a second group which partially overlapped with both the first and third groups. The third group consisted of normal hearts with lung disease, normal hearts not taking adriamycin (18, 1.53), normal hearts taking adriamycin (22, 1.50), congestive heart failure (19, 1.50), arteriosclerotic heart disease, normal hearts (15, 1.29), chronic obstructive pulmonary disease and acute myocardial infarction. The LV/RV is not specific for mitral insufficiency. Idiopathic myocardiography, and normal hearts with lung disease on chest x-ray (metastases, cancer of the lung, infiltrates, fibrosis, and/or COPD) cannot be differentiated on a statistical basis. The mitral insufficiency group had the greatest values of LV/RV. It appears that decreased RV amplitude seen with diseases causing strain on the right ventricle will result in elevated LV/RV ratios.« less

Previous studies have suggested that leukocyte telomere length is associated with risk of developing prostate cancer. Investigations of leukocyte telomere length as a prognostic factor in prostate cancer are, however, lacking. In this study, leukocyte telomere length was investigated both as a risk marker, comparing control subjects and patient risk groups (based on serum levels of prostate-specific antigen, tumor differentiation, and tumor stage), and as a prognostic marker for metastasis-free and cancer-specific survival. Relative telomere length was measured by a well-established quantitative polymerase chain reaction method in 415 consecutively sampled individuals. Statistical evaluation included 162 control subjects without cancer development during follow-up and 110 untreated patients with newly diagnosed localized prostate cancer at the time of blood draw. Leukocyte telomere length did not differ significantly between control subjects and patients, or between patient risk groups. Interestingly, however, and in line with our previous results in breast and kidney cancer patients, relative telomere length at diagnosis was an independent prognostic factor. Patients with long leukocyte telomeres (⩾median) had a significantly worse prostate cancer-specific and metastasis-free survival compared to patients with short telomere length. In contrast, for patients who died of other causes than prostate cancer, long relative telomere length was not coupled to shorter survival time. To our knowledge, these results are novel and give further strength to our hypothesis that leukocyte telomere length might be used as a prognostic marker in malignancy.

Purpose: To describe radiation therapy cases during which voluntary incident reporting occurred; and identify patient- or treatment-specific factors that place patients at higher risk for incidents. Methods and Materials: We used our institution's incident learning system to build a database of patients with incident reports filed between January 2011 and December 2013. Patient- and treatment-specific data were reviewed for all patients with reported incidents, which were classified by step in the process and root cause. A control group of patients without events was generated for comparison. Summary statistics, likelihood ratios, and mixed-effect logistic regression models were used for group comparisons. Results:more » The incident and control groups comprised 794 and 499 patients, respectively. Common root causes included documentation errors (26.5%), communication (22.5%), technical treatment planning (37.5%), and technical treatment delivery (13.5%). Incidents were more frequently reported in minors (age <18 years) than in adult patients (37.7% vs 0.4%, P<.001). Patients with head and neck (16% vs 8%, P<.001) and breast (20% vs 15%, P=.03) primaries more frequently had incidents, whereas brain (18% vs 24%, P=.008) primaries were less frequent. Larger tumors (17% vs 10% had T4 lesions, P=.02), and cases on protocol (9% vs 5%, P=.005) or with intensity modulated radiation therapy/image guided intensity modulated radiation therapy (52% vs 43%, P=.001) were more likely to have incidents. Conclusions: We found several treatment- and patient-specific variables associated with incidents. These factors should be considered by treatment teams at the time of peer review to identify patients at higher risk. Larger datasets are required to recommend changes in care process standards, to minimize safety risks.« less

Peritonitis remains an important cause of morbidity and mortality in peritoneal dialysis (PD) patients, but its incidence and the distribution of causative organisms vary widely between institutions and age groups. This study was performed to investigate the recent status and risk factors of PD-related peritonitis and to clarify differences between age groups. We retrospectively reviewed the medical records of 119 PD patients treated at our department between January 2002 and January 2013. We calculated both overall and organism-specific peritonitis rates and also analyzed risk factors. Sixty-three episodes of peritonitis occurred during 261.5 patient-years for an incident rate of 0.24 episodes/patient-year. Multivariate analysis showed that older age (≥65 years) and hypoalbuminemia (<3.0 g/dL) were associated with an increased risk of peritonitis (P = 0.035 and P = 0.029, respectively). In elderly patients (≥65 years old), the rate of peritonitis due to Gram-positive and Gram-negative bacteria was 0.17 and 0.08 episodes/patient-year, respectively, and Gram-positive peritonitis was markedly more frequent than in younger patients (<65 years old). In particular, there was a high frequency of Staphylococcus aureus peritonitis in elderly patients (0.09 episodes/patient-year) and it had a poor outcome. At our department, the risk of peritonitis was increased in older patients and patients with hypoalbuminemia. The distribution of causative organisms was markedly different between age groups and analysis of organism-specific peritonitis rates helped to identify current problems with our PD program. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

To evaluate the information needs of ductal carcinoma in situ (DCIS) patients. Four focus groups involving 24 previously treated DCIS patients were conducted to develop a comprehensive list of questions they felt were important to have answered at the time of diagnosis. Using a survey, a separate group of patients treated for DCIS then rated the importance of having each of these questions addressed before treatment decision making. Response options were "essential," "desired," "not important," "no opinion," and "avoid." For each essential/desired question, respondents specified how addressing it would help them: "understand," "decide," "plan," "not sure," or "other." Focus group participants generated 117 questions used in the survey. Fifty-seven patients completed the survey (55% response rate). Respondents rated a median of 66 questions as essential. The most commonly cited reason for rating a question essential was to "understand," followed by to "decide." The top questions women deemed essential to help them understand were disease specific, whereas the top questions deemed essential to help women decide were predominantly treatment specific, pertaining to available options, recurrence and survival outcomes, and timelines to decide and start treatment. DCIS patients want a large number of questions answered, mostly for understanding, and also for deciding and planning. A core set of questions that most patients consider essential for decision making has been formulated and may be used in the clinical setting and in research to develop educational resources and decision-making tools specific to DCIS.

Spinal deformities are very challenging to treat and have a great risk of neurological complications due to hardware placement during corrective surgery. Various techniques have been introduced to ensure safe and accurate placement of pedicle screws. Patient-specific screw guides with pre-drawn and pre-validated trajectory seems to be an attractive option. We have focused on developing 3D printing technique for complex spinal deformities in India. This study also aimed to compare the placement of pedicle screw with 3D printing and free hand technique. This is a retrospective comparative clinical study at an academic institutional setting. A total of 20 patients were enrolled during the study, 10 were operated with the help of 3D printing (group 1) and 10 were operated with freehand technique (group 2). Group 1 included 6 congenital, 3 adolescent idiopathic scoliosis (AIS), one post tubercular kyphosis and Group 2 included 5 congenital, 4 AIS and one post tubercular kyphosis patient. Primary outcomes were measured in terms of screw violation and secondary outcome were measured in terms of Surgical time, Blood loss, Radiation exposure (no. of shoots required) and complications. MIMICS v18.0 Software was used for 3D reconstruction from CT scan images of all the patients. 3-Matic software was used to create drill guide. 3-D printer from Stratasys Mojo ABS P 430 model material cartilage (a thermoplastic material) was used for printing of vertebrae model and jigs. Two sample test of proportion was used to compare correctly and wrongly pedicle screw placement with 3D printing and freehand technique. T-test with equal variance was used for operating surgical time and blood loss. This work was carried out by collaboration of Orthopaedics Department, All India Institute of Medical Sciences (AIIMS), New Delhi and Biomedical Engineering Department, Indian Institute of Technology (IIT) Delhi. This project received the grant of USD 60000 from Department of Biotechnology (DBT), Government of India under DBT Innovative young Biotechnologist Award. No study-specific conflicts of interest-associated biases is declared by the authors. No superior or inferior screw violation was observed in any of our patients in either group. We found significant (p=0.03) difference between 2 groups regarding perfect screw placement in favour of 3D printing. There were 13 grade 2 medial perforations in free hand group and 3 in 3D printing group. There was no grade 3 medial perforation in either group. There were 6 grade 2 lateral perforations in free hand group and 7 in 3D printing group were observed. There were 3 grade 3 lateral perforation in free hand group and 2 in 3D printing group were observed. Analysis showed a statistically significant (p-value: 0.005) medial violation in free hand group. Surgical time was significantly (p-value: 0.03) less in 3D printing group as compared to free hand group. Mean Blood loss was higher in free hand group, however it was not statistically significant (p-value: 0.3) in 3D printing group. Fluoroscopic shots required were less in number in 3D printing group in comparison to free hand group. There was no neurological deficit in any of the patient in any group. In our study, focusing on spinal deformities statistically significant higher rate of accurate screw positioning and higher number of inserted screws with 3D printing was possible due to enhanced safety particularly at apical levels. As such, spinal deformities are difficult to treat worldwide. In India, these deformities are often neglected and present at a very late and much more deformed state when their treatment becomes even more challenging. Developing these patient specific drill templates will enable an average spine surgeon to treat these patients with much ease and safety. Copyright © 2018. Published by Elsevier Inc.

The preservation of the nipple areolar complex (NAC) for cancer treatment is still a matter of debate because of suspected increase of local recurrence and surgery-specific complications. The aim of the study was to investigate both the relapse risk associated with nipple sparing mastectomy (NSM) for breast cancer and women's satisfaction with preservation of the NAC. We included retrospectively all patients who had skin-sparing mastectomy (SSM) or NSM from 2007 to 2012 for breast cancer or ductal carcinoma in situ (DCIS). We compared NSM and SSM group for oncological and surgical outcomes. Patients' satisfaction and quality of life has been evaluated by a specifically designed questionnaire. We included 63NSM (41.5%) and 89SM (58.5%). Eighty-nine (58.6%) patients had DCIS, and the other had small invasive disease. Median follow-up was 42 (IQR: 18-58) months. Local recurrence rate was 1.7% (n=1) in the NSM group and 0% in the SSM group without recurrence in the preserved nipple. After NSM, one patient had complete NAC necrosis, and three patients suffered partial necrosis. Satisfaction with the NAC was higher in the NSM group compared to the SSM group with delayed reconstruction of the nipple (75% vs. 59%, P=0.14). Patients with NSM required less psychological support before (P=0.028) and immediately after surgery (P=0.14) than patients in the SSM group. NSM can successfully and safely be performed for pre-invasive and small invasive breast cancer. Besides esthetic aspects, preserving the nipple may ease the acceptance of these radical form of surgery. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Disease-Specific Trends of Comorbidity Coding and Implications for Risk Adjustment in Hospital Administrative Data.

To investigate changes in comorbidity coding after the introduction of diagnosis related groups (DRGs) based prospective payment and whether trends differ regarding specific comorbidities. Nationwide administrative data (DRG statistics) from German acute care hospitals from 2005 to 2012. Observational study to analyze trends in comorbidity coding in patients hospitalized for common primary diseases and the effects on comorbidity-related risk of in-hospital death. Comorbidity coding was operationalized by Elixhauser diagnosis groups. The analyses focused on adult patients hospitalized for the primary diseases of heart failure, stroke, and pneumonia, as well as hip fracture. When focusing the total frequency of diagnosis groups per record, an increase in depth of coding was observed. Between-hospital variations in depth of coding were present throughout the observation period. Specific comorbidity increases were observed in 15 of the 31 diagnosis groups, and decreases in comorbidity were observed for 11 groups. In patients hospitalized for heart failure, shifts of comorbidity-related risk of in-hospital death occurred in nine diagnosis groups, in which eight groups were directed toward the null. Comorbidity-adjusted outcomes in longitudinal administrative data analyses may be biased by nonconstant risk over time, changes in completeness of coding, and between-hospital variations in coding. Accounting for such issues is important when the respective observation period coincides with changes in the reimbursement system or other conditions that are likely to alter clinical coding practice. © Health Research and Educational Trust.

The aims of this study were to investigate the safety of combined intravenous, oral and topical tranexamic acid (TXA) in primary total knee replacement. We assessed dose-related efficacy on hemoglobin level, transfusion, length of stay and thromboembolic complications. In addition, TXA safety in patients with previous history of thromboembolism >12months ago was monitored specifically. From January 2013 until January 2016, 922 patients were included who received TXA after primary total knee replacement. Patients without TXA administration or with thromboembolic events <12months ago were excluded. TXA dosage groups were divided into ≤10mg/kg, >10-25mg/kg and >25-50mg/kg. Between the three TXA groups no significant difference was found in thromboembolic complications (deep venous thrombosis (DVT) and pulmonary embolism (PE)), wound leakage and transfusion rate. For patients with DVT or PE in their history >12months ago specifically, no more complications were noted in higher-TXA-dosage groups compared to the low-dosage group. Length of stay was shorter in the highest-TXA-dosage group compared with lower-dosage groups (median two vs three days). With high TXA dose a smaller difference between pre- and postoperative Hb was found: the >25-50mg/kg TXA group had a 0.419mmol/l smaller decrease in postoperative hemoglobin compared to the lowest-dosage group (P<0.05). Combined intravenous, oral and topical TXA is effective in knee replacement and can safely be given to patients with a thromboembolic history >12months ago. High dosage (>25-50mg/kg) TXA resulted in the smallest decrease in postoperative hemoglobin. Copyright © 2017 Elsevier B.V. All rights reserved.

Deep venous thrombosis (DVT) is the most common form of vascular involvement in Behçet's disease (BD). Chronic post-thrombotic syndrome (PTS) develops in up to one-half of patients with DVT and is associated with impaired quality of life (QoL). There are no data on the severity of DVT-related PTS and its effect on QoL in patients with vascular BD (VBD). We aimed to evaluate PTS and venous disease-specific QoL in patients with VBD. This study included 50 patients (41 men, nine women) with VBD and 31 individuals matched for age and gender (22 men, nine women) with DVT associated with non-BD causes. The Villalta scale was used to assess PTS. The Venous Disability Score and the Venous Clinical Severity Score were used for the assessment of venous disease. Venous disease-specific QoL was measured through Venous Insufficiency Epidemiological and Economic Study Quality of Life/Symptom (VEINES-QoL/Sym) questionnaire. The Behçet Syndrome Activity Score (BSAS) questionnaire was used to assess disease activity. We observed a significantly lower risk of PTS together with significantly better VEINES-QoL/Sym, and Venous Disability Score in the VBD group compared with the non-BD group. When VBD patients with PTS were compared with patients without PTS, VEINES-QoL/Sym, and Venous Clinical Severity Score were significantly worse. BSAS was also significantly higher in patients with PTS. An inverse correlation was found between the VEINES-QoL and the BSAS in multivariate analysis. There were no differences between anticoagulant users and nonusers regarding the presence of PTS and scores of all of the venous assessment tools. We found lower PTS risk and better venous disease-specific QoL, symptom severity, and venous disability scores in VBD patients compared with the non-BD group. Venous disease-specific QoL negatively correlated with disease activity. Effective control of vascular inflammation through treatment in VBD might explain lower rates of PTS and better venous QoL outcomes in VBD patients. Our results suggest that successful control of BD activity might decrease the development of PTS, improve venous disease-specific QoL, and prevent relapses in VBD.

Truly informed consent is an elusive goal, seldom attained in medical or surgical practice. Patients often do not fully understand procedures and therapies they undergo or the associated sequelae. Historically, informed consent and patient education have been limited to physician discussions, sometimes with the addition of simple visual aids. More recently, there is a growing body of decision aids available, including interactive multimedia patient educational modules that review preoperative through postoperative care, risks, benefits, alternatives, different surgical options, as well as commonly asked questions. We hypothesized that the addition of a Web-based educational tool would positively impact attainment of informed consent and satisfaction in plastic surgery patients. We performed a prospective randomized controlled study comparing patients who presented in consultation for breast reconstruction, breast reduction, and abdominoplasty. Patients received standard patient education along with a procedure-specific (study) or general patient safety (control) Web-based educational module. Informed consent was measured using a surgical-focused, modified version of the Shared Decision-making 25 index tool. Patient demographic information as well as surrogate markers of familiarity with technology were recorded preoperatively and postoperatively. Comparisons were made between study and control groups, procedure subgroups, and preoperative and postoperative time points. Demographic factors and consent variables were compared among experimental and procedure groups. Data were collected from 65 patients preoperatively and 48 patients postoperatively. Thirty patients competed both surveys. Overall, no differences in patient characteristics or familiarity with technology were observed between experimental groups. Demographic characteristics were also similar between groups. No meaningful differences were identified in comparisons between experimental groups on either cross-sectional or longitudinal analyses. Nearly all patient responses were consistent with being well informed and satisfied with the educational process. Overall, patients undergoing plastic surgery procedures are adequately informed and have a high degree of satisfaction regarding their patient education. The addition of a Web-based informed consent tool did not make a demonstrable difference in informed consent.

Previous studies have suggested that Plasmodium falciparum (P. falciparum) specific IgE in the form of immune complexes crosslinking the low-affinity receptor (CD23) on monocyte results in tumor necrosis factor (TNF)-α and nitric oxide (NO) production. However, the roles of these parameters in severity and immune protection are still unclear. This study aimed to determine the association between CD23 expression on monocytes, plasma soluble CD23 (sCD23), total IgE, malaria-specific IgE and IgG, and TNF-α levels in P. falciparum infected patients. We evaluated 64 uncomplicated (UC) and 25 severe patients (S), admitted at the Hospital for Tropical Diseases, Mahidol University, and 34 healthy controls (C) enrolled in 2001. Flow cytometry and enzyme linked immunosorbent assays (ELISA) demonstrated that trends of the CD23 expression, levels of sCD23 and specific IgE were higher in the S group as compared to those in the UC and C groups. Plasma levels of P. falciparum specific IgE in the UC (p=0.011) and S groups (p=0.025) were significantly higher than those in C group. In contrast the TNF-α levels tended to be higher in the UC than those in the S (p=0.343) and significantly higher than those in C (p=0.004) groups. The specific IgG levels in UC were significantly higher than those in S and C (p<0.001) groups. At admission, a strong significant negative correlation was found between specific IgG and sCD23 (r=-0.762, p=0.028), and TNF-α and IgE-IgG complexes (r=-0.715, p=0.002). Significant positive correlations between levels of specific IgE and TNF-α (r=0.575, p=0.010); and sCD23 (r=0.597, p=0.000) were also observed. In conclusion, our data suggest that CD23 expression and malaria-specific IgE levels may be involved in the severity of the disease while TNF-α and the malaria-specific IgG may correlate with protection against falciparum malaria.

Park, Kelly K

2015-12-01

Many opportunities exist for residents to get involved in advocacy in dermatology, from national to grassroots levels. Residents also should be aware of opportunities to get involved in patient advocacy and become familiar with the myriad of patient advocacy groups that exist. These groups offer support and education for patients and initiate research efforts for specific dermatologic conditions that provide support for patients beyond what can be offered during a standard office visit. The value of resident involvement in advocacy also is discussed.

The concepts of "frontal" and "dysexecutive" syndromes are still a matter of debate in the literature. These terms are often used interchangeably but can be distinguished when considering specific frontal behavioural deficits which occur during social interaction. Despite being of interest for the clinical assessment and care management of patients with anterior brain damage, few studies have tried to disentangle the specificity of each syndrome. We report the case of eight patients with frontal lobe damage who were assigned to one of two groups based on whether or not they showed a dysexecutive syndrome. The nondysexecutive group differed from the dysexecutive group in showing environmental dependency phenomena, behavioural disorders triggered by social interaction. By adopting an interactionist perspective, this pilot study contributes to defining more precisely the distinction between "frontal" and "dysexecutive" syndromes. The discussion focuses on the potential interest of the interactionist approach in designing appropriate methodologies of assessment and rehabilitation of patients with frontal lobe syndrome.

During the last two decades, understanding and experience of microsurgical reconstruction have increased. This is linked to improved instruments and technical devices, as well as to the increased number of available donor sites for microvascular flap transfer. If the indication is appropriate, it is now possible to perform personalised, safe and successful microsurgical reconstructions, almost independently of the patients' age. Despite these constant developments, there is little specific literature on microsurgery related to the specific problems of the elderly patient. During two consensus workshops organised by the DAM (German Speaking Working Group for Microsurgery of the Peripheral Nerves and Vessels), the latest findings and experience with microsurgical reconstruction in the elderly patient were presented by a group of experts and current recommendations were formulated. On the basis of these consensus workshops and the current literature, this article discusses important issues in this area. Georg Thieme Verlag KG Stuttgart · New York.

Apolipoprotein E4 serum concentration for increased sensitivity and specificity of diagnosis of drug treated Alzheimer's disease patients vs. drug treated parkinson's disease patients vs. age-matched normal controls.

Inasmuch as Alzheimer's disease (AD) is difficult to diagnose, patients with suspected dementias are often given FDA approved medications, including donepezil, rivastigmine, memantine HCl, or a combination, prior to diagnosis, and some respond with improved cognition. The present study demonstrates how concentrations of a select group of serum protein biomarkers can provide the basis for sensitive and specific differential diagnosis of AD in drug treated patients. Optimization is addressed by taking into account whether the patients and controls have or do not have increased risk of AD die to the presence or absence of Apolipoprotein E4. For differential diagnosis of AD, prospectively collected newly drawn blood serum samples were obtained from drug treated Alzheimer's disease and Parkinson's disease patients from a first (39 drug treated DTAD, and 31 age matched normal controls) and second medical center (56 drug treated DTPD, 47 age-matched normal controls). Analytically validated quantitative 2D gel electrophoresis (%CV ≤ 20%; LOD ≥ 0.5 ng/spot, 300 μg/ml of blood serum) was employed with patient and control sera for differential diagnosis of AD. Protein quantitation was subjected to statistical analysis by single variable Dot, Box and Whiskers and Receiver Operator Characteristics (ROC) plots for individual biomarker performance, and multivariate linear discriminant analysis for joint performance of groups of biomarkers. Protein spots were identified and characterized by LC MS/MS of in-gel trypsin digests, amino acid sequence spans of the identified peptides, and the protein spot molecular weights and isoelectric points. The single variable statistical profiles of 58 individual protein biomarker concentrations of the DTAD patient group differed from those of the normal and/or the disease control groups. Multivariate linear discriminant analysis of blood serum concentrations of the 58 proteins distinguished drug treated Alzheimer's disease (DTAD) patients from drug treated Parkinson's disease (DTPD) patients and age matched normal controls (collectively not-DTAD, DTAD Sensitivity 87.2%, Not-DTAD Specificity 87.2). Moreover, when the patients and controls were stratified into carriers or non-carriers of Alzheimer's high risk Apolipoprotein E 4 allele and/or the Apolipoprotein E4 protein, the DTAD, DTPD and control Apo E4 (+) profiles were more divergent from one another than the corresponding Apo E4 (-) profiles. Multivariate stepwise linear discriminant analysis selected 17 of the 58 biomarkers as optimal and complimentary for distinguishing Apo E4 (+) DTAD patients from Apo E4 (+) DTPD and Apo E4 (+) controls (collectively Apo E4 (+) not-DTAD, DTAD Sensitivity 100%, not-DTAD Specificity 100%) and 22 of the 58 biomarkers for distinguishing Apo E4 (-) DTAD patients from Apo E4 (-) DTPD and Apo E4 (-) controls (collectively Apo E4 (-) not-DTAD, DTAD Sensitivity 94.4%, not- DTAD Specificity 94.4%). Only 6 of the selected proteins were common to both the Apo E4 (+) and the Apo E4 (-) discriminant functions. Recombining of the results of Apo E4 (+) and Apo E4 (-) discriminations provided overall sensitivity for total DTAD of 97.4% and specificity for total not-DTAD of 95.7%. These results can form the basis of a blood test for differential diagnosis of Alzheimer's disease patients already under treatment (DTAD) by anti dementia drugs, including donepezil, rivastigmine, memantine HCl, or a combination thereof. Also, the profile differences and the rise in specificity and sensitivity obtained by handling the Apo E4 (+) and Apo E4 (-) groups separately supports the concept that they are different patient and control populations in terms of the "normal" physiology, the pathophysiology of disease, and the response to drug treatment. Taking that into account enables increased sensitivity and specificity of differential diagnosis of Alzheimer's disease.

In ascertained allergic sensitization to Vespa crabro (VC) venom, the European guidelines still consider venom immunotherapy (VIT) with Vespula (VE) venom sufficient to achieve an adequate protection against VC. However, antigen 5 immunoblotting studies showed that a genuine sensitization to VC venom may exist. In such cases, a specific VC venom would be preferable for VIT treatment. Since in the last few years, VC venom extracts became available for diagnosis and desensitization, we assessed the efficacy and safety of VIT with a VC-VIT, compared to VE extract. Patients stung by VC, and carefully diagnosed for specific sensitization and indication to VIT underwent a 5-year course of immunotherapy with either VE or VC extracts . The severity of reactions at the first sting (pre-VIT) and after field re-stings (during VIT) were compared. Eighty-three patients, treated with VE extract and 130 patients treated with VC extract completed the 5-year course of VIT. Only a fraction of those patients (43,8%) were field-re-stung by VC: 64 patients on VC VIT and 69 on VE VIT. In the VC VIT group, reactions at re-sting were: 50 negative, 12 large local reactions, 4 systemic reactions (Muller grade I). In this group the VC VIT efficacy was 93,8%. In the VE VIT treated group the reactions at VC re-sting were: 51 negative, 10 large local reactions and 9 systemic reactions (5 Muller I, 3 Mueller III, 1 Muller IV). In this group the overall efficacy of VIT was 87,0%. The difference in efficacy between the two groups was not statistically significant, as previously reported in literature. Nonetheless, field sting systemic reactions Muller III and IV were recorded only in those patients receiving VE VIT. This observation suggests that in patients with ascertained VC-induced allergic reactions a specific VC VIT, where available, would be more adequate, at least concerning the safety profile.

Autonomic behavior is subject to direct suggestion. We found that patients undergoing major operations benefit more from instruction than from information and reassurance. We compared the return of intestinal function after intra-abdominal operations in 2 groups of patients: the suggestion group received specific instructions for the early return of gastrointestinal motility, and the control group received an equal-length interview offering reassurance and nonspecific instructions. The suggestion group had a significantly shorter average time to the return of intestinal motility, 2.6 versus 4.1 days. Time to discharge was 6.5 versus 8.1 days. Covariates including duration of operation, amount of intraoperative bowel manipulation, and amount of postoperative narcotics were also examined using the statistical model analysis of covariance. An average savings of $1,200 per patient resulted from this simple 5-minute intervention. In summary, the use of specific physiologically active suggestions given preoperatively in a beleivable manner can reduce the morbidity associated with an intra-abdominal operation by reducing the duration of ileus.

Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The medianmore » duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.« less

Purpose Medulloblastoma comprises four distinct molecular subgroups: WNT, SHH, Group 3, and Group 4. Current medulloblastoma protocols stratify patients based on clinical features: patient age, metastatic stage, extent of resection, and histologic variant. Stark prognostic and genetic differences among the four subgroups suggest that subgroup-specific molecular biomarkers could improve patient prognostication. Patients and Methods Molecular biomarkers were identified from a discovery set of 673 medulloblastomas from 43 cities around the world. Combined risk stratification models were designed based on clinical and cytogenetic biomarkers identified by multivariable Cox proportional hazards analyses. Identified biomarkers were tested using fluorescent in situ hybridization (FISH) on a nonoverlapping medulloblastoma tissue microarray (n = 453), with subsequent validation of the risk stratification models. Results Subgroup information improves the predictive accuracy of a multivariable survival model compared with clinical biomarkers alone. Most previously published cytogenetic biomarkers are only prognostic within a single medulloblastoma subgroup. Profiling six FISH biomarkers (GLI2, MYC, chromosome 11 [chr11], chr14, 17p, and 17q) on formalin-fixed paraffin-embedded tissues, we can reliably and reproducibly identify very low-risk and very high-risk patients within SHH, Group 3, and Group 4 medulloblastomas. Conclusion Combining subgroup and cytogenetic biomarkers with established clinical biomarkers substantially improves patient prognostication, even in the context of heterogeneous clinical therapies. The prognostic significance of most molecular biomarkers is restricted to a specific subgroup. We have identified a small panel of cytogenetic biomarkers that reliably identifies very high-risk and very low-risk groups of patients, making it an excellent tool for selecting patients for therapy intensification and therapy de-escalation in future clinical trials.

Effectiveness of mat Pilates or equipment-based Pilates in patients with chronic non-specific low back pain: a protocol of a randomised controlled trial

PubMed Central

2013-01-01

Background Chronic low back pain is an expensive and difficult condition to treat. One of the interventions widely used by physiotherapists in the treatment of chronic non-specific low back pain is exercise therapy based upon the Pilates principles. Pilates exercises can be performed with or without specific equipment. These two types of Pilates exercises have never been compared on a high-quality randomised controlled trial. Methods/design This randomised controlled trial with a blinded assessor will evaluate eighty six patients of both genders with chronic low back pain, aged between 18 and 60 years, from one Brazilian private physiotherapy clinic. The patients will be randomly allocated into two groups: Mat Group will perform the exercises on the ground while the Equipment-based Group will perform the Pilates method exercises on the following equipment: Cadillac, Reformer, Ladder Barrel, and Step Chair. The general and specific disability of the patient, kinesiophobia, pain intensity and global perceived effect will be evaluated by a blinded assessor before randomisation and at six weeks and six months after randomisation. In addition, the expectation of the participants and their confidence with the treatment will be evaluated before randomisation and after the first treatment session, respectively. Discussion This will be the first study aiming to compare the effectiveness of Mat and Equipment-based Pilates exercises in patients with chronic non-specific low back pain. The results may help health-care professionals in clinical decision-making and could potentially reduce the treatment costs of this condition.

Non-specific chronic back pain (CBP) is often accompanied by psychological trauma, but treatment for this associated condition is often insufficient.Nevertheless, despite the common co-occurrence of pain and psychological trauma, a specific trauma-focused approach for treating CBP has been neglected to date. Accordingly, eye movement desensitization and reprocessing (EMDR), originally developed as a treatment approach for posttraumatic stress disorders, is a promising approach for treating CBP in patients who have experienced psychological trauma.Thus, the aim of this study is to determine whether a standardized, short-term EMDR intervention added to treatment as usual (TAU) reduces pain intensity in CBP patients with psychological trauma vs. TAU alone. The study will recruit 40 non-specific CBP patients who have experienced psychological trauma. After a baseline assessment, the patients will be randomized to either an intervention group (n = 20) or a control group (n = 20). Individuals in the EMDR group will receive ten 90-minute sessions of EMDR fortnightly in addition to TAU. The control group will receive TAU alone. The post-treatment assessments will take place two weeks after the last EMDR session and six months later.The primary outcome will be the change in the intensity of CBP within the last four weeks (numeric rating scale 0-10) from the pre-treatment assessment to the post-treatment assessment two weeks after the completion of treatment.In addition, the patients will undergo a thorough assessment of the change in the experience of pain, disability, trauma-associated distress, mental co-morbidities, resilience, and quality of life to explore distinct treatment effects. To explore the mechanisms of action that are involved, changes in pain perception and pain processing (quantitative sensory testing, conditioned pain modulation) will also be assessed.The statistical analysis of the primary outcome will be performed on an intention-to-treat basis. The secondary outcomes will be analyzed in an explorative, descriptive manner. This study adapts the standard EMDR treatment for traumatized patients to patients with CBP who have experienced psychological trauma. This specific, mechanism-based approach might benefit patients. This trial has been registered with ClinicalTrials.gov (NCT01850875).

To test if functional electrical stimulation (FES) can enhance the recovery of upper extremity function during early stroke rehabilitation. Open-label block-randomized trial, begun during inpatient rehabilitation and continued at the patients' home. Patients were assigned to either FES combined with task-specific upper extremity rehabilitation (n = 7) or a control group that received task-specific therapy alone (n = 8) over 12 weeks. Outcome measures . Hand function (Box & Blocks, B & B; Jebsen-Taylor light object lift, J-T) and motor control (modified Fugl-Meyer, mF-M) were video-recorded for both upper extremities at baseline, 4, 8, and 12 weeks. B&B mean score at 12 weeks favored (P = .049) the FES group (42.3 +/- 16.6 blocks) over the control group (26.3 +/- 11.0 blocks). The FES group J-T task was 6.7 +/- 2.9 seconds and faster (P = .049) than the 11.8 +/- 5.4 seconds of the control group. Mean mF-M score of the FES group at 12 weeks was 49.3 +/- 5.1 points out of 54, compared to the control group that scored 40.6 +/- 8.2 points (P = .042). All patients regained hand function. Upper extremity task-oriented training that begins soon after stroke that incorporates FES may improve upper extremity functional use in patients with mild/moderate paresis more than task-oriented training without FES.

2013-04-01

A growing number of studies are attempting to understand how effective cognitive interventions may be for patients with amnestic mild cognitive impairment (aMCI), particularly in relation to their memory problems. The present study aimed to explore the benefits of a working memory (WM) training program in aMCI patients. Patients (N = 20) were randomly assigned to two training programs: the experimental group practiced with a verbal WM task, while the active control group conducted educational activities on memory. Results showed that the aMCI patients completing the WM training obtained specific gains in the task trained with some transfer effects on other WM measures (visuospatial WM) and on processes involved in or related to WM, e.g. fluid intelligence (the Cattell test) and long-term memory. This was not the case for the aMCI control group, who experienced only a very limited improvement. This pilot study suggests that WM training could be a valuable method for improving cognitive performance in aMCI patients, possibly delaying the onset of Alzheimer's disease.

This study investigates the utility of serum tryptase for the confirmation of shrimp-induced anaphylaxis. Patients with a history of shrimp allergy and positive skin prick tests (SPT) to commercial shrimp extract were recruited for shrimp challenges. Serum total tryptase was obtained at baseline and 60 min (peak) after the onset of symptoms. Thirty-nine patients were challenged. There were 12 patients with anaphylaxis, 20 with mild reactions and 7 without symptoms (control group). Characteristic features and baseline tryptase were not different among the 3 groups. The peak tryptase levels were higher than the baseline in anaphylaxis and mild reaction groups (P<0.05). The delta-tryptase (peak minus baseline) and the tryptase ratio (peak divided by baseline) in the anaphylaxis group were higher than the mild reaction and control groups (P<0.01). The optimum cut-off for peak tryptase to confirm anaphylaxis was 2.99 µg/L with 50% sensitivity, 85% specificity, 3.33 positive likelihood ratio (LR) and 0.59 negative LR. The manufacturer's cut-off for peak tryptase was >11.4 µg/L with 17% sensitivity, 100% specificity, infinity positive LR and 0.83 negative LR. The best cut-off for delta-tryptase was ≥0.8 µg/L with 83% sensitivity, 93% specificity, 11.86 positive LR and 0.18 negative LR. The best cut-off for tryptase ratio was ≥1.5 with 92% sensitivity, 96% specificity, 23 positive LR and 0.08 negative LR. The peak tryptase level should be compared with the baseline value to confirm anaphylaxis. The tryptase ratio provide the best sensitivity, specificity, positive and negative LR than a single peak serum tryptase for the confirmation of shrimp-induced anaphylaxis.

INTRODUCTION Medical specialties' core curricula should take into account functions to be carried out, positions to be filled and populations to be served. The functions in the professional profile for specialty training of Cuban intensive care and emergency medicine specialists do not include all the activities that they actually perform in professional practice. OBJECTIVE Define the specific functions and procedural skills required of Cuban specialists in intensive care and emergency medicine. METHODS The study was conducted from April 2011 to September 2013. A three-stage methodological strategy was designed using qualitative techniques. By purposive maximum variation sampling, 82 professionals were selected. Documentary analysis and key informant criteria were used in the first stage. Two expert groups were formed in the second stage: one used various group techniques (focus group, oral and written brainstorming) and the second used a three-round Delphi method. In the final stage, a third group of experts was questioned in semistructured in-depth interviews, and a two-round Delphi method was employed to assess priorities. RESULTS Ultimately, 78 specific functions were defined: 47 (60.3%) patient care, 16 (20.5%) managerial, 6 (7.7%) teaching, and 9 (11.5%) research. Thirty-one procedural skills were identified. The specific functions and procedural skills defined relate to the profession's requirements in clinical care of the critically ill, management of patient services, teaching and research at the specialist's different occupational levels. CONCLUSIONS The specific functions and procedural skills required of intensive care and emergency medicine specialists were precisely identified by a scientific method. This product is key to improving the quality of teaching, research, administration and patient care in this specialty in Cuba. The specific functions and procedural skills identified are theoretical, practical, methodological and social contributions to inform future curricular reform and to help intensive care specialists enhance their performance in comprehensive patient care.

Patients with borderline personality disorder (BPD) show various psychopathological symptoms and suffer especially from disturbance in their identity. The purpose of the study was to investigate changes-particularly in affective BPD symptoms and identity diffusion-during a structured, disorder-specific inpatient treatment (DST) that combined a psychodynamic transference-focused psychotherapy approach with modules of dialectical behavioural skills training. In a prospective, two-group comparison trial, 44 patients with BPD were assessed with questionnaires addressing identity diffusion and state, as well as trait affective psychopathology, before and after 12 weeks of inpatient treatment. Thirty-two patients received DST, whereas 12 patients were given inpatient treatment-as-usual (TAU). The patients were allocated in a non-random procedure for two groups, in order of admission and availability of treatment options in the DST unit. In the pre-post-comparison, the DST group showed a significant decrease in identity diffusion (p < 0.001) and improvements in instability of the image of self and others (p < 0.008), as well as in pathological (trait and state) symptoms. However, there was no significant improvement in the TAU group. After a 12-week inpatient treatment, the findings indicate significant improvements in the DST group in typical affective borderline symptomatology and in the personality structure feature of identity diffusion. This highlights the significance of a short-term specific inpatient therapy for BPD. A structured, disorder-specific inpatient treatment of patients diagnosed with borderline personality disorder (BPD) combined a psychodynamic transference-focused psychotherapy treatment approach (focusing on pathological features in personality organization, particularly on non-integrated images of self and others) with modules of dialectical behavioural skills training. This treatment is associated with a decrease in identity diffusion of these patients after 12 weeks of treatment. The treatment is also related to a significant decrease in borderline typical psychopathological symptoms such as depressive symptoms, as well as an improvement in state anger. The outcomes of this structured, disorder-specific inpatient treatment of severely ill BPD patients indicated the relevance of intensive short-term inpatient psychotherapy in terms of psychopathological improvements as well as initial changes in structural personality organization.

To study the distribution characteristics of lactobacillus in the vaginal mucosa of patients with HPV infection. The planting density of lactobacillus in vaginal secretions of 95 cases with HPV16/18 infection and 90 cases of normal women of childbearing age were observed by oil microscope. And the strains of vaginal lactobacilli in two groups were analyzed using species-specific polymerase chain reaction (Species-specific PCR) and the distribution of vaginal lactobacilli in patients with HPV16/18 infection were investigated. In HPV16/18 infective groups, the planting density of lactobacillus in the vaginal mucosa was 104 (68-186)/HP. It was significantly lower than that of the normal group (234 (161-326)/HP, P<0.05). Compared with the normal group, the positive rates of lactobacillus iners, lactobacillus crispatus, and lactobacillus gasseri were significantly lower in HPV16/18 infection group (P<0.05). The HPV16/18 infection is associated with the decreased number of lactobacillus and the imbalance of vaginal flora; Lactobacillus iners, lactobacillus crispatus, and lactobacillus gasseri may play a key role in maintaining the vaginal micro ecological environment.

The incidence of gastric cancer has been increasing among elderly persons in Japan. This study aimed to clarify risk factors for postoperative complications in oldest old patients with gastric cancer. One-hundred ninety patients more than 75 years old with gastric cancer underwent gastrectomy between 2000 and 2011. Patients were classified into two groups: group A included 29 patients who were 85 years or older (oldest old patients), and group B included 161 patients who were 75-84 years of age. Perioperative parameters associated with complications were compared in each group. The preoperative estimated glomerular filtration rate was significantly lower in group A (p = 0.03). The two groups significantly differed in performance status (p = 0.018). Patients in group A received a lesser extent of lymph node dissection and had fewer lymph nodes excised. As a result, the duration of the operation was significantly shorter in group A. There were no significant differences in the frequency or grade of total complications or mortality between the two groups. Operative hemorrhage (>300 ml) and Hiroshima POSSUM (predicted morbidity risk >40) were risk factors in both groups A and B; the risk factors of preoperative serum albumin level and prognostic nutritional index (PNI) were specific to group A. Adjustments to the extent of surgery among oldest old patients most likely reduces the incidence of postoperative complications in this group. Preoperative serum albumin level and PNI are significant predictors of postoperative complications in oldest old patients with gastric cancer.

Anti-double-stranded (ds)DNA antibodies are serological markers of systemic lupus erythematosus (SLE). Of all anti-dsDNA antibody detection methods, the Crithidia luciliae immunofluorescence test (CLIFT) is thought to have the highest specificity for SLE. However, the clinical application is hampered by the low diagnostic sensitivity. A CLIFT with modified assay buffer (mCLIFT) was developed and compared with conventional CLIFT, using sera from 110 patients with SLE, 89 anti-dsDNA ELISA-positive patients with other diseases (non-SLE group A), 157 non-SLE patients with undetectable anti-dsDNA antibodies by ELISA (non-SLE group B), 77 disease controls (non-SLE group C), and 50 healthy blood donors. Out of the 110 anti-dsDNA antibody ELISA-positive SLE patients, 84 (76.4%) demonstrated a positive kinetoplast staining, using the mCLIFT, compared to only 42.3%, using the conventional CLIFT. The diagnostic specificity of mCLIFT was 100% with healthy blood donors and 98.1% with the non-SLE group C (anti-nuclear antibodies negative; no signs or symptoms of an autoimmune disease) included. In the non-SLE groups A and B with various other autoimmune diseases or symptoms of a possible autoimmune disease, positive mCLIFT results were obtained in 33.7% and 3.2%, respectively. In conclusion, by modification of the assay buffer, a significant increase in sensitivity of the CLIFT could be observed while retaining the high specificity for SLE. Further investigation is required to check whether the CLIFT-positive non-SLE patients develop SLE and whether anti-dsDNA antibodies detected by the mCLIFT represent a pathogenetic and diagnostic subgroup of autoantibodies that may improve the early diagnosis of SLE or SLE-overlap syndromes.

To determine whether specific psychosocial interventions can ease discomfort in palliative care (PC) patients, particularly in those with high levels of pain or emotional distress. Changes in the psychological parameters of 8333 patients were assessed in a quasi-experimental, prospective, multicenter, single group pretest/post-test study. Psychosocial care was delivered by 29 psychosocial care teams (PSTs; 137 professionals). Pre- and post-intervention changes in these variables were assessed: mood, anxiety, and emotional distress. Patients were classified as complex, when presented with high levels of anxiety, mood, suffering (or perception of time as slow), and distress (or unease, or discomfort), or noncomplex. These groups were compared to assess changes in suffering-related parameters from baseline. Psychosocial interventions reduced patients' suffering. These interventions were more effective in complex patients. After successive psychosocial interventions, the level of suffering in complex patients decreased until close to parity with noncomplex patients, suggesting that patients with major complexity could benefit most from specific psychosocial treatment. These findings support the importance of assessing and treating patients' psychosocial needs.

Empathy is a rather elaborated human ability and several recent studies highlight significant impairments in patients suffering from psychiatric disorders, such as schizophrenia, bipolar disorder or major depression. Therefore, the present study aimed at comparing behavioral empathy performance in schizophrenia, bipolar and depressed patients with healthy controls. All subjects performed three tasks tapping the core components of empathy: emotion recognition, emotional perspective taking and affective responsiveness. Groups were matched for age, gender, and verbal intelligence. Data analysis revealed three main findings: First, schizophrenia patients showed the strongest impairment in empathic performance followed by bipolar patients while depressed patients performed similar to controls in most tasks, except for affective responsiveness. Second, a significant association between clinical characteristics and empathy performance was only apparent in depression, indicating worse affective responsiveness with stronger symptom severity and longer duration of illness. Third, self-report data indicate that particularly bipolar patients describe themselves as less empathic, reporting less empathic concern and less perspective taking. Taken together, this study constitutes the first approach to directly compare specificity of empathic deficits in severe psychiatric disorders. Our results suggest disorder-specific impairments in emotional competencies that enable better characterization of the patient groups investigated and indicate different psychotherapeutic interventions.

Although some clinical reports suggest patient-specific instrumentation in TKA may improve alignment, reduce surgical time, and lower hospital costs, it is unknown whether it improves pain- and function-related outcomes and gait. We hypothesized that TKA performed with patient-specific instrumentation would improve patient-reported outcomes measured by validated scoring tools and level gait as ascertained with three-dimensional (3-D) analysis compared with conventional instrumentation 3 months after surgery. We randomized 40 patients into two groups using either patient-specific instrumentation or conventional instrumentation. Patients were evaluated preoperatively and 3 months after surgery. Assessment tools included subjective functional outcome and quality-of-life (QOL) scores using validated questionnaires (New Knee Society Score(©) [KSS], Knee Injury and Osteoarthritis Outcome Score [KOOS], and SF-12). In addition, gait analysis was evaluated with a 3-D system during level walking. The study was powered a priori at 90% to detect a difference in walking speed of 0.1 m/second, which was considered a clinically important difference, and in a post hoc analysis at 80% to detect a difference of 10 points in KSS. There were improvements from preoperatively to 3 months postoperatively in functional scores, QOL, and knee kinematic and kinetic gait parameters during level walking. However, there was no difference between the patient-specific instrumentation and conventional instrumentation groups in KSS, KOOS, SF-12, or 3-D gait parameters. Our observations suggest that patient-specific instrumentation does not confer a substantial advantage in early functional or gait outcomes after TKA. It is possible that differences may emerge, and this study does not allow one to predict any additional variances in the intermediate followup period from 6 months to 1 year postoperatively. However, the goals of the study were to investigate the recovery period as early pain and functional outcomes are becoming increasingly important to patients and surgeons. Level I, therapeutic study.

The aim of our study was to investigate whether two different daily doses of a high monounsaturated fatty acid (MUFA) specific diabetes enteral formula could improve nutritional variables as well as metabolic parameters. We conducted a randomized, open-label, multicenter, parallel group study. 27 patients with diabetes mellitus type 2 with recent weight loss were randomized to one of two study groups: group 1 (two cans per day) and group 2 (three cans per day) for a ten week period. A significative decrease of HbA1c was detected in both groups. The decrease 0.98% (confidence interval 95% 0.19-1.88) was higher in group 2 than group 1 0.60% (confidence interval 95% 0.14-1.04). A significant increase of weight, body mass index, fat mass, albumin, prealbumin and transferrin was observed in both groups without statistical differences in this improvement between both groups. The increase of weight 4.59kg (confidence interval 95% 1.71-9.49) was higher in group 2 than group 1 1.46% (confidence interval 95% 0.39-2.54). Gastrointestinal tolerance (diarrhea episodes) with both formulas was good, without statistical differences (7.60% vs 7.14%: ns). A high monounsaturated fatty acid diabetes-specific supplement improved HbA1c and nutritional status. These improvements were higher with three supplements than with two per day.

The diagnosis of IgE-mediated immediate reactions to penicillins can be supported by in vivo or in vitro tests using classical benzylpenicillin determinants. The wide variety of beta-lactams and the description of new specificities requires a re-evaluation of the different tests available. The objective was to evaluate the diagnostic capacity of Pharmacia CAP System RAST FEIA amoxicilloyl c6 (AXO) and benzylpenicilloyl c1 (BPO) in patients with a documented IgE-mediated penicillin allergy. We studied 129 patients in five groups. Groups 1, 2, and 3 had developed an immediate reaction after penicillin treatment. Group 1 (n=19) were skin test positive to amoxicillin (AX) and/or BPO and/or minor determinant mixture (MDM); group 2 (n=29) were skin test positive to AX but negative to BPO and MDM; and group 3 (n=26) were skin test negative to all determinants, the diagnosis being confirmed by a previous repetitive history or controlled administration. Two control groups, one with nonimmediate reactions -- group 4 (n=25) -- and one with good tolerance to penicillin -- group 5 (n=30) -- were included. All samples were analyzed in vitro for AXO and BPO, and the results compared to the in vivo diagnosis. AX was the drug most often involved. In group 1, 53% were in vitro positive for AXO and 68% for BPO, but 74% had at least one positive test result. In group 2, only 10% had a positive in vitro test to BPO compared to 41% to AXO. In group 3, 42% had positive BPO and/or AXO in vitro tests. In the control groups 4 and 5, the negative in vitro results for AXO were 96% and 100%, and for BPO 100% and 97%, respectively. A positive correlation between specific IgE levels and the time interval from the reaction to the evaluation was found only for group 3. This in vitro assay is beneficial for evaluating subjects allergic to beta-lactams. It is necessary to test for specific IgE to AXO in addition to BPO in patients with immediate allergic reactions after AX. The combination of in vivo and in vitro tests for estimating IgE antibodies to penicillins is important because of the existence of patients with a positive history but negative skin test.

The superior temporal sulcus (STS) is specifically involved in processing the human voice. Profound acquired deafness by post-meningitis ossified cochlea and by bilateral vestibular schwannoma in neurofibromatosis type 2 patients are two indications for auditory brainstem implantation (ABI). In order to objectively measure the cortical voice processing of a group of ABI patients, we studied the activation of the human temporal voice areas (TVA) by PET H(2)(15)O, performed in a group of implanted deaf adults (n=7) with more than two years of auditory brainstem implant experience, with an intelligibility score average of 17%+/-17 [mean+/-SD]. Relative cerebral blood flow (rCBF) was measured in the three following conditions: during silence, while passive listening to human voice, and to non-voice stimuli. Compared to silence, the activations induced by voice and non-voice stimuli were bilaterally located in the superior temporal regions. However, compared to non-voice stimuli, the voice stimuli did not induce specific supplementary activation of the TVA along the STS. The comparison of ABI group with a normal-hearing controls group (n=7) showed that TVA activations were significantly enhanced among controls group. ABI allowed the transmission of sound stimuli to temporal brain regions but lacked transmitting the specific cues of the human voice to the TVA. Moreover, among groups, during silent condition, brain visual regions showed higher rCBF in ABI group, although temporal brain regions had higher rCBF in the controls group. ABI patients had consequently developed enhanced visual strategies to keep interacting with their environment.

  The objective of this study was to correlate dermatoglyphics and cheiloscopy with genetic inheritance in cleft lip and cleft palate patients.   This was a case-control study to look for asymmetry in finger and lip print patterns. All of the participants were divided into two equal groups (40 mothers and 40 fathers in each group). The data were analyzed by three evaluators who were blind to the study to avoid any chances of error.   A sample of 160 sporadic participants were identified and evaluated. Group A was composed of 80 healthy parents not affected by cleft lip and cleft palate but had at least one child born with nonsyndromic cleft. Group B consisted of 80 healthy parents not affected by cleft lip and cleft palate and had healthy children without cleft lip and cleft palate.   Main outcome measures were marked dermatoglyphic asymmetry and specific lip print pattern in the study group.   We found marked asymmetry in various fingerprints and specific type II and type III lip print in the study group when compared with the control group. It was observed that groove count on the lip was significantly more frequent in study group parents.   Our study determined that there is a significant correlation between increased dermatoglyphic asymmetry and specific type II and type III lip print pattern in parents of children born with cleft. This could act as an important screening marker for the prediction of cleft lip and cleft palate inheritance.

Measuring the free:total ratio of prostate-specific antigen (f/t-PSA) can improve the specificity of single-serum PSA values, distinguishing between benign prostatic hyperplasia (BPH) and prostatic carcinoma (PCa) in men over the age of 50. Additionally, clinical trials have shown that dihydroxyvitamin D3 can slow the rate of PSA rise in PCa patients. However, little is known regarding the applicability of those findings in men undergoing chronic peritoneal dialysis (CPD). In the present study, we investigated the prevalence of increased serum PSA levels among CPD patients and correlated those values with serum levels of vitamin D [25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3]. We undertook a cross-sectional study of 71 male CPD patients without a known history of prostate cancer from 24 centers in Canada, Greece, and Turkey. All of the patients were more than 50 years of age. In these patients, we measured serum concentrations of PSA, free PSA (f-PSA), total PSA (t-PSA), prostate alkaline phosphatase (PAP), 25-hydroxyvitamin D3, 1,25-dihydroxyvitamin D3, and intact parathyroid hormone (iPTH). We recorded serum PSA levels < 4 ng/mL in 62 patients (87.3%, group A) and levels > 4 ng/mL in 9 patients (12.7%, group B). The f/t-PSA ratio was < 0.25 in 16 patients (22.5%). Group B patients were older than those in group A (median: 73 years vs. 65 years, p < 0.01) and had a lower body weight (median: 66.5 kg vs. 76.7 kg, p < 0.05). We observed no statistically significant difference between the two groups for serum 1,25-dihydroxyvitamin D3 (median: 9.8 ng/mL vs. 10.1 ng/mL) or 25-hydroxyvitamin D3 (8 ng/mL vs. 8.2 ng/mL) levels. Also, we observed no correlation between vitamin D levels and f/t-PSA, but iPTH levels were significantly higher in group A (200.5 pg/mL vs. 61.2 pg/mL, p < 0.04). Also, serum PAP levels correlated significantly with PSA (r = 0.49, p = 0.01) and with f-PSA (r = 0.56, p = 0.000). Our results showed no clear relationship between vitamin D and serum levels of PSA or-of f/t-PSA in PD patients. However, further studies are needed to better define the uses of these PSA markers in PD patients because, in such patients, other relevant factors might be implicated in their predictive value.

Social media (SoMe) has evolved to be a platform that patients use to seek information prior to an operation, share perioperative and postoperative journey, provide feedback, offer and receive support. While there have been studies looking at the evolution and usage of SoMe either by patients or by surgeons, there is no information that compares its usefulness for both the groups. The aim of this study was to compare the view held by patients and surgeons, towards social media and other internet resources, in relation to one commonly performed operation. A questionnaire was presented to 648 consecutive patients who attended our clinic for consultation for primary breast augmentation from September 2016 to March 2017. A separate "surgeons' questionnaire" was answered by a group of 138 plastic surgeons who either worked in our clinic, had previously done fellowship with us or were visiting the clinic. All 138 surgeons and 648 patients responded to the questionnaire. 91.4% of patients said that they had searched online and 61.4% had searched in specific online groups for information on breast augmentation. 88.9% of patients had specifically looked for clinical photographs and 73.4% had specifically searched for unfavorable reviews of the surgeon. In comparison, 72.5% of surgeons thought that over three quarters of patients gather information on the internet while only 20.3% thought that over three-quarters of patients use social media for their information. 52.5% of surgeons have noticed that social media affected their consultations. With the evolution of Internet and related technologies, the role of social media continues to increase. While patients use social media to help make their decision, it is not the only deciding factor. Surgeons appear to underestimate the patients' use of these technologies. There is concern in each group about the amount of inaccurate information on the social media. This underlines the importance of providing factual, evidence-based information to the patients. © 2018 The American Society for Aesthetic Plastic Surgery, Inc.

Laparoscopy has been used for the diagnosis and treatment for hemodynamically stable patients with penetrating abdominal trauma. This study evaluated whether diagnostic and therapeutic laparoscopy can be used as effectively in select patients with blunt abdominal trauma. All hemodynamically stable patients undergoing operations for blunt abdominal trauma over a 10-year period (2006–2015) at a tertiary medical center were included. Patients undergoing laparotomy were categorized as group A. Patients who underwent laparoscopy were categorized as group B. The clinical outcomes of the 2 groups were compared. There were 139 patients in group A and 126 patients in group B. Group A patients were more severely injured (mean injury severity score of 23.3 vs. 18.9, P < .001) and had a higher frequency of traumatic brain injuries (25.2% vs. 14.3%, P = .039). The sensitivity and specificity of diagnostic laparoscopy for patients in group B was 99.1% and 100.0%, respectively. No non-therapeutic laparotomies were performed in group B, and the success rate of therapeutic laparoscopy was 92.0% (103/112) for patients with significant intra-abdominal injuries. Patients in the 2 groups had similar perioperative and postoperative outcomes in terms of operation times, blood loss, blood transfusion requirements, mortality, and complications (all, P > .05). Laparoscopy is a feasible and safe tool for the diagnosis and treatment of hemodynamically stable patients with blunt abdominal trauma who require surgery. PMID:29470527

To determine whether 3-dimensional (3D) speckle-tracking echocardiography could provide a new way to assess myocardial viability in patients with myocardial infarction (MI). Forty-five patients with MI underwent routine echocardiography, 2-dimensional (2D) speckle-tracking echocardiography, and 3D speckle-tracking echocardiography. Radionuclide myocardial perfusion/metabolic imaging was used as a reference standard to define viable and nonviable myocardia. Among 720 myocardial segments in 45 patients, 368 showed abnormal motion on routine echocardiography; 204 of 368 were categorized as viable on single-photon emission computed tomography/positron emission tomography (SPECT/PET), whereas 164 were defined as nonviable; 300 normal segments on SPECT/PET among 352 segments without abnormal motion on routine echocardiography were categorized as a control group. The radial, longitudinal, 3D, and area strain on 3D speckle-tracking echocardiography had significant differences between control and nonviable groups (P < .001), whereas none of the parameters had significant differences between control and viable groups. There were no significant differences in circumferential, radial, and longitudinal peak systolic strain from 2D speckle-tracking echocardiography between viable and nonviable groups. Although there was no significant difference in circumferential strain between the groups, radial and longitudinal strain from 3D speckle-tracking echocardiography decreased significantly in the nonviable group. Moreover, 3D and area strain values were lower in the nonviable segments than the viable segments. By receiver operating characteristic analysis, radial strain from 3D speckle-tracking echocardiography with a cutoff of 11.1% had sensitivity of 95.1% and specificity of 53.4% for viable segments; longitudinal strain with a cutoff of 14.3% had sensitivity of 65.2% and specificity of 65.7%; 3D strain with a cutoff of 17.4% had sensitivity of 70.6% and specificity of 77.2%; and area strain with a cutoff of 23.2% had sensitivity of 91.5% and specificity of 82.8%. Three-dimensional speckle-tracking echocardiography might have potential for detection of myocardial viability in patients with cardiac dysfunction due to MI.

Even though temperature is a continuous quantitative variable, its measurement has been considered a snapshot of a process, indicating whether a patient is febrile or afebrile. Recently, other diagnostic techniques have been proposed for the association between different properties of the temperature curve with severity of illness in the Intensive Care Unit (ICU), based on complexity analysis of continuously monitored body temperature. In this study, we tried to assess temperature complexity in patients with systemic inflammation during a suspected ICU-acquired infection, by using wavelets transformation and multiscale entropy of temperature signals, in a cohort of mixed critically ill patients. Twenty-two patients were enrolled in the study. In five, systemic inflammatory response syndrome (SIRS, group 1) developed, 10 had sepsis (group 2), and seven had septic shock (group 3). All temperature curves were studied during the first 24 hours of an inflammatory state. A wavelet transformation was applied, decomposing the signal in different frequency components (scales) that have been found to reflect neurogenic and metabolic inputs on temperature oscillations. Wavelet energy and entropy per different scales associated with complexity in specific frequency bands and multiscale entropy of the whole signal were calculated. Moreover, a clustering technique and a linear discriminant analysis (LDA) were applied for permitting pattern recognition in data sets and assessing diagnostic accuracy of different wavelet features among the three classes of patients. Statistically significant differences were found in wavelet entropy between patients with SIRS and groups 2 and 3, and in specific ultradian bands between SIRS and group 3, with decreased entropy in sepsis. Cluster analysis using wavelet features in specific bands revealed concrete clusters closely related with the groups in focus. LDA after wrapper-based feature selection was able to classify with an accuracy of more than 80% SIRS from the two sepsis groups, based on multiparametric patterns of entropy values in the very low frequencies and indicating reduced metabolic inputs on local thermoregulation, probably associated with extensive vasodilatation. We suggest that complexity analysis of temperature signals can assess inherent thermoregulatory dynamics during systemic inflammation and has increased discriminating value in patients with infectious versus noninfectious conditions, probably associated with severity of illness.

Recently, other diagnostic techniques have been proposed for the association between different properties of the temperature curve with severity of illness in the Intensive Care Unit (ICU), based on complexity analysis of continuously monitored body temperature. In this study, we tried to assess temperature complexity in patients with systemic inflammation during a suspected ICU-acquired infection, by using wavelets transformation and multiscale entropy of temperature signals, in a cohort of mixed critically ill patients. Methods Twenty-two patients were enrolled in the study. In five, systemic inflammatory response syndrome (SIRS, group 1) developed, 10 had sepsis (group 2), and seven had septic shock (group 3). All temperature curves were studied during the first 24 hours of an inflammatory state. A wavelet transformation was applied, decomposing the signal in different frequency components (scales) that have been found to reflect neurogenic and metabolic inputs on temperature oscillations. Wavelet energy and entropy per different scales associated with complexity in specific frequency bands and multiscale entropy of the whole signal were calculated. Moreover, a clustering technique and a linear discriminant analysis (LDA) were applied for permitting pattern recognition in data sets and assessing diagnostic accuracy of different wavelet features among the three classes of patients. Results Statistically significant differences were found in wavelet entropy between patients with SIRS and groups 2 and 3, and in specific ultradian bands between SIRS and group 3, with decreased entropy in sepsis. Cluster analysis using wavelet features in specific bands revealed concrete clusters closely related with the groups in focus. LDA after wrapper-based feature selection was able to classify with an accuracy of more than 80% SIRS from the two sepsis groups, based on multiparametric patterns of entropy values in the very low frequencies and indicating reduced metabolic inputs on local thermoregulation, probably associated with extensive vasodilatation. Conclusions We suggest that complexity analysis of temperature signals can assess inherent thermoregulatory dynamics during systemic inflammation and has increased discriminating value in patients with infectious versus noninfectious conditions, probably associated with severity of illness.

Detection of specific IgE antibodies against food materials indicates allergic sensitization. Some very widely consumed foods materials such as garlic and onion have rarely been investigated for their allergenic potential. To assess the presence of garlic and onion specific IgE antibodies in patients investigated for food allergy. Radioallergosorbent test (RAST) results of 108 patients with clinical suspicion of food allergy who were specifically screened for garlic and onion specific IgE antibodies along with other food allergens were analyzed retrospectively at King Khalid University Hospital between January 2008 and April 2009. This group of patients included 73 males and 35 females with mean age 27+13.2 years. Estimation of garlic and onion specific IgE antibodies was performed by radioallergosorbent test (RAST) using Pharmacia ImmunoCAP 250 analyzer. Out of the 108 patients 15 (13.8%) had garlic and onion specific IgE antibodies in their sera. Garlic specific IgE antibodies with the RAST scores between one to four were present in 14 and onion specific IgE were detected in 13 patients. For garlic specific IgEs majority of patients (08) had RAST score of one (0.35-0.69 kU/L) and for onion specific IgE antibodies seven patients had RAST score of two (0.70-3.49 kU/L). Among these patients 12 (80%) were found to have coexisting specific IgE antibodies against garlic and onion. The presence of garlic and onion specific IgE antibodies in a sizeable number of patients indicate sensitization and allergenic potential of these food materials.

The mechanism of long-term B cell immunity against donor blood group antigens in recipients who undergo ABO-incompatible (ABOi) living-donor kidney transplantation (LKTx) is unknown. To address this question, we evaluated serial anti-A and anti-B antibody titers in 50 adult recipients. Donor-specific antibody titers remained low (≤1:4) in 42 recipients (84%). However, antibodies against nondonor blood group antigens were continuously produced in recipients with blood type O. We stimulated recipients' peripheral blood mononuclear cells in vitro to investigate whether B cells produced antibodies against donor blood group antigens in the absence of graft adsorption in vivo. Antibodies in cell culture supernatant were measured using specific enzyme-linked immunosorbent assays (ELISAs). Thirty-five healthy volunteers and 57 recipients who underwent ABO-compatible LKTx served as controls. Antibody production in vitro against donor blood group antigens by cells from ABOi LKTx patients was lower than in the control groups. Immunoglobulin deposits were undetectable in biopsies of grafts of eight recipients with low antibody titers (≤1:4) after ABOi LKTx. One patient with blood type A1 who received a second ABOi LKTx from a type B donor did not produce B-specific antibodies. These findings suggest diminished donor-specific antibody production function in the setting of adult ABOi LKTx. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

To explore the application of multiplex nested methylated specific polymerase chain reaction (PCR) in the early diagnosis of epithelial ovarian carcinoma (EOC). Serum and fresh tissue samples were collected from 114 EOC patients. RUNX3, TFPI2 and OPCML served as target genes. Methylation levels of tissues were assessed by multiplex nested methylated specific PCR, the results being compared with those for carcinoma antigen 125 (CA125). The serum free deoxyribose nucleic acid (DNA) methylation spectrum of EOC patients was completely contained in the DNA spectrum of cancer tissues, providing an accurate reflection of tumor DNA methylation conditions. Serum levels of CA125 and free DNA methylation in the EOC group were evidently higher than those in benign lesion and control groups (p<0.05). Patients with early EOC had markedly lower serum CA125 than those with advanced EOC (p<0.05), but there was no significant difference in free DNA methylation (p>0.05). The sensitivity, specificity and positive predicative value (PPV) of multiplex nested methylated specific PCR were significantly higher for detection of all patients and those with early EOC than those for CA125 (p<0.05). In the detection of patients with advanced EOC, the PPV of CA125 detection was obviously lower than that of multiplex nested methylated specific PCR (p>0.05), but there was no significant difference in sensitivity (p>0.05). Serum free DNA methylation can be used as a biological marker for EOC and multiplex nested methylated specific PCR should be considered for early diagnosis since it can accurately determine tumor methylation conditions.

To assess the clinical manifestations and prognosis of Spanish patients with systemic sclerosis (SSc) according to their immunological profile. From the Spanish Scleroderma Study Group or RESCLE (Registro de ESCLErodermia as Spanish nomenclature) Registry we selected those patients in which anti-centromere (ACA), anti-topoisomerase I (ATA), and anti-RNA polymerase III (ARA) antibodies had been determined, and a single positivity for each SSc specific antibody was detected. Demographic, clinical, laboratory, and survival data were compared according to the serologic status of these antibodies. Overall, 209 SSc patients were included. In 128 (61%) patients ACA was the only positive antibody, 46 (22%) were only positive for ATA, and 35 (17%) for ARA. Of note, the three groups were mutually exclusive. In univariate analysis, patients with ACA presented more frequently limited cutaneous SSc (lcSSc) (p<0.001), whereas diffuse cutaneous SSc (dcSSc) was the most frequent subtype in patients with ATA (54%) and ARA (62%) (both p<0.001). Positive patients for ARA showed the highest prevalence of joint involvement (p<0.001) and those from ATA group had a higher prevalence of interstitial lung disease (ILD) (p<0.001). Scleroderma renal crisis was more frequent in the ARA group (p<0.001). In multivariate analysis, ACA were associated with female gender and were protective for dcSSc and ILD. ATA were found to be protective for lcSSc and they were independently associated with interstitial reticular pattern. ARA positivity was independently associated with dcSSc. We did not find differences in mortality between the three groups. In Spanish SSc patients, the presence of SSc specific antibodies conferred a distinctive clinical profile.

Celiac disease (CD) is common yet under-detected. A point of care test (POCT) may improve CD detection. We aimed to assess the diagnostic performance of an IgA/IgG-deamidated gliadin peptide (DGP)-based POCT for CD detection, patient acceptability, and inter-observer variability of the POCT results. From 2013-2017, we prospectively recruited patients referred to secondary care with gastrointestinal symptoms, anemia and/or weight loss (group 1); and patients with self-reported gluten sensitivity with unknown CD status (group 2). All patients had concurrent POCT, IgA-tissue transglutaminase (IgA-TTG), IgA-endomysial antibodies (IgA-EMA), total IgA levels, and duodenal biopsies. Five hundred patients completed acceptability questionnaires, and inter-observer variability of the POCT results was compared among five clinical staff for 400 cases. Group 1: 1000 patients, 58.5% female, age 16-91, median age 57. Forty-one patients (4.1%) were diagnosed with CD. The sensitivities of the POCT, IgA-TTG, and IgA-EMA were 82.9, 78.1, and 70.7%; the specificities were 85.4, 96.3, and 99.8%. Group 2: 61 patients, 83% female; age 17-73, median age 35. The POCT had 100% sensitivity and negative predictive value in detecting CD in group 2. Most patients preferred the POCT to venepuncture (90.4% vs. 2.8%). There was good inter-observer agreement on the POCT results with a Fleiss Kappa coefficient of 0.895. The POCT had comparable sensitivities to serology, and correctly identified all CD cases in a gluten sensitive cohort. However, its low specificity may increase unnecessary investigations. Despite its advantage of convenience and rapid results, it may not add significant value to case finding in an office-based setting.

Overuse of cranial computed tomography scans in children with blunt head trauma unnecessarily exposes them to radiation. The Pediatric Emergency Care Applied Research Network (PECARN) blunt head trauma prediction rules identify children who do not require a computed tomography scan. Electronic health record (EHR) based clinical decision support (CDS) may effectively implement these rules but must only be provided for appropriate patients in order to minimize excessive alerts. To develop, implement and evaluate site-specific groupings of chief complaints (CC) that accurately identify children with head trauma, in order to activate data collection in an EHR. As part of a 13 site clinical trial comparing cranial computed tomography use before and after implementation of CDS, four PECARN sites centrally developed and locally implemented CC groupings to trigger a clinical trial alert (CTA) to facilitate the completion of an emergency department head trauma data collection template. We tested and chose CC groupings to attain high sensitivity while maintaining at least moderate specificity. Due to variability in CCs available, identical groupings across sites were not possible. We noted substantial variability in the sensitivity and specificity of seemingly similar CC groupings between sites. The implemented CC groupings had sensitivities greater than 90% with specificities between 75-89%. During the trial, formal testing and provider feedback led to tailoring of the CC groupings at some sites. CC groupings can be successfully developed and implemented across multiple sites to accurately identify patients who should have a CTA triggered to facilitate EHR data collection. However, CC groupings will necessarily vary in order to attain high sensitivity and moderate-to-high specificity. In future trials, the balance between sensitivity and specificity should be considered based on the nature of the clinical condition, including prevalence and morbidity, in addition to the goals of the intervention being considered.

Pituitary masses are common lesions accounting for about 15-20% of all brain tumours. Oozing blood is an annoyance in microscopic sublabial trans-sphenoidal approach for these masses. There have been many ways of reducing the ooze, having their own pros and cons. To find out the efficacy and safety of clonidine in reducing blood loss in pituitary adenoma surgery through a randomized masked trial. It was a prospective randomized controlled trial done. Total 50 patients of pituitary adenomas were randomized into two groups. Group A (25 patients) was given 200 μg clonidine orally, while Group B (25 patients) was given placebo. Surgeon, anaesthesiologist and patient were blinded for the trial. Sublabial trans-septal trans-sphenoidal approach to sella and excision of mass was performed in each patient. Patients were studied for pre-, intra- and post-operative blood pressure and heart rate, pre- and post-operative imaging findings, intra-operative blood loss, bleeding grading by surgeon, surgeon's satisfaction about condition of specific part and quality of surgical field, operative time and extent of resection. Blood loss during the surgery, operative time and bleeding grading by the surgeon were found significantly less in the clonidine group, while quality of surgical field, condition of the specific part and extent of resection were found significantly better in the clonidine group (p value <.05). There was no untoward adverse effect of the drug in the test group. Clonidine is a safe and effective drug to reduce bleeding in trans-sphenoidal microscopic pituitary adenoma surgeries.

The aim of this study was to investigate the effect of a specific therapeutic jaw exercise on the temporomandibular disorders of patients with chronic whiplash-associated disorders. Ninety-four consecutive patients with whiplash-related conditions were referred to and accepted for a treatment period at a center for functional evaluation and rehabilitation during 2001-2002. The patients followed a program of physical therapy, occupational therapy, and pain management. At the start of their stay, they were examined by a physician specialized in rehabilitation medicine and also by a dentist who performed a functional examination of the stomatognathic system. Of the 93 patients who accepted participation in the study, 55 were diagnosed with temporomandibular disorders and chronic whiplash-associated disorders in accordance with the inclusion criteria. They were randomized into a jaw exercise group (n = 25), who performed specific therapeutic jaw exercises, and a control group (n = 30). Both groups undertook the whiplash rehabilitation program at the center. There were no inter- or intra-group differences in symptoms and signs of temporomandibular disorders at baseline, nor at the 3-week and 6-month follow-ups, except for an increase of maximum active mouth-opening capacity in the control group. In conclusion, the therapeutic jaw exercises, in addition to the regular whiplash rehabilitation program, did not reduce symptoms and signs of temporomandibular disorders in patients with chronic whiplash-associated disorders.

Diabetic patients without active DFU were classified according to the International Working Group Risk Stratification System (RSS) and categorized according to the results of the Semmes-Wenstein Monofilament (SWM) and biothesiometer measurements or the SFT. The main outcome evaluated was the development of DFU. median follow-up was 42 [38-44] months. Sixty patients (22.8%) developed DFU after a median of 6.2 [3-17] months. Ten patients that were included in the no-risk group (group 0) based on the SWM and biothesiometer results developed DFU. Thus the sensitivity of this approach was 83.33% and the specificity was 50.47%. Based on the SFT results, all patients that developed DFU were included in the correct risk group. This approach had 100% sensitivity and 31.53% specificity. Regarding the diagnostic accuracy of the two Methods, the respective AUC values were 0.776 (95% CI 0.702-0.849) and 0.816 (95% CI 0.757-0.874). SFT improved RSS in diabetic patients in a specialized diabetic foot unit. SFT categorized patients correctly according to the risk of developing DFU. Copyright © 2017 Elsevier B.V.

To develop a descriptive system for a glaucoma-specific preference-based health-related quality of life (HRQoL) instrument: the Health Utility for Glaucoma (HUG-5). The descriptive system was developed in two stages: item identification and item selection. A systematic literature review of HRQoL assessment of glaucoma was conducted using a comprehensive search strategy. Purposeful sampling was used to recruit patients with different clinical characteristics. Relevant items were presented to glaucoma patients through face-to-face, semi-structured interviews. Framework methodology was applied to analyze interview content. The recurring themes identified through an iterative content analysis represented topics of most importance and relevance to patients. These themes formed the domains of the HUG-5 descriptive system. Three versions of the descriptive system, differing in explanatory detail, were pilot tested using a focus group. The literature review identified 19 articles which contained 266 items. These items were included for the full text review and were used to develop an interview guide. From twelve patient interviews, 22 themes were identified and grouped into five domains that informed the five questions of the descriptive system. The HUG-5 measures visual discomfort, mobility, daily life activities, emotional well-being, and social activities. Each question has five response levels that range from "no problem" to "severe problem". The focus group comprised of seven additional patients unanimously preferred the version that contained detailed, specific examples to support each question. A 5-domain descriptive system of a glaucoma-specific preference-based instrument, the HUG-5, was developed and remains to be evaluated for validity and reliability in the glaucoma patient population.

This study attempts to clarify the clinical characteristics of chronic dizziness and its relationships with specific vestibular, oculomotor, autonomic and psychiatric dysfunctions. 73 Patients with idiopathic chronic dizziness were recruited and classified based on history taking and clinical examination into the following four clinical subgroups; vestibular migraine (VM), dysautonomia, psychogenic, and unspecified groups. They were also evaluated using oculomotor, otolithic and autonomic function tests, and psychologic investigation. Patients in the VM group showed a high proportion of abnormality on smooth pursuit and otolithic function testing compared to the other groups. The dysautonomia group revealed significant abnormalities in sympathetic and cardiovagal autonomic function, while the psychogenic group had a high frequency of abnormality in sympathetic autonomic testing and in Beck's anxiety inventory scale. The unspecified group showed abnormalities on saccade, smooth pursuit and autonomic function testing. Clinical classification of patients with chronic dizziness was relevant and they showed a correlation with disease-specific abnormal results in oculomotor, otolithic, autonomic function and psychology testing. Appropriate diagnostic investigation based on precise clinical diagnosis of chronic dizziness reduces the need for extensive laboratory testing, neuroimaging, and other low-yield tests.

Patient support groups serve an important function for those affected by a disease but especially for people with a rare disease. Because of the complexity of Wilson disease there are some unique and difficult problems faced by groups that advocate for these patients. We give a comparative overview of the differences between groups that support people with more common diseases and groups that serve the rare disease population. The history and current status of the Wilson Disease Association and other worldwide Wilson disease groups are described and information about other organizations that support Wilson disease in additional ways is explained. The specific challenges faced in the support of Wilson disease patients are outlined and possible solutions proposed. Drawing from experience in speaking with many patients, we discuss some of the most common questions that are asked by patients who are seeking a possible diagnosis or are already on treatment. There are many options for improving patient advocacy efforts in the future that we hope will be accomplished. © 2017 Elsevier B.V. All rights reserved.

There are studies demonstrating that skin-test sensitivity to penicillins can decrease over time and that allergic patients may lose sensitivity if the responsible compounds are avoided. With regard to subjects with IgE-mediated hypersensitivity to cephalosporins, however, such studies are lacking. We evaluated prospectively in a 5-year follow-up 72 cephalosporin-allergic patients. After the first evaluation, patients were classified into two groups according to their patterns of allergologic-test positivity: to both penicillins and cephalosporins (group A), or only to cephalosporins (group B). Skin tests and serum-specific IgE assays were repeated 1 year later and, in case of persistent positivity, 3 and 5 years after the first allergologic examination. Seven (43.7%) of the 16 subjects of group A and 38 (67.8%) of the 56 patients of group B became negative; one was lost to follow-up. Patients of group B became negative sooner and more frequently than group A subjects. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Patients' trust in their physicians has recently become a focus of concern, largely owing to the rise of managed care, yet the subject remains largely unstudied. We undertook a qualitative research study of patients' self-reported experiences with trust in a physician to gain further understanding of the components of trust in the context of the patient-physician relationship. Twenty-nine patients participants, aged 26 to 72, were recruited from three diverse practice sites. Four focus groups, each lasting 1.5 to 2 hours, were conducted to explore patients' experiences with trust. Focus groups were audio-recorded, transcribed, and coded by four readers, using principles of grounded theory. The resulting consensus codes were grouped into seven categories of physician behavior, two of which related primarily to technical competence (thoroughness in evaluation and providing appropriate and effective treatment) and five of which were interpersonal (understanding patient's individual experience, expressing caring, communicating clearly and completely, building partnership/sharing power and honesty/respect for patient). Two additional categories were predisposing factors and structural/staffing factors. Each major category had multiple subcategories. Specific examples from each major category are provided. These nine categories of physician behavior encompassed the trust experiences related by the 29 patients. These categories and the specific examples provided by patients provide insights into the process of trust formation and suggest ways in which physicians could be more effective in building and maintaining trust.

Impaired sensory integration contributes to balance disorders in patients with multiple sclerosis (MS). The objective of this paper is to compare the effects of sensory integration balance training against conventional rehabilitation on balance disorders, the level of balance confidence perceived, quality of life, fatigue, frequency of falls, and sensory integration processing on a large sample of patients with MS. This single-blind, randomized, controlled trial involved 80 outpatients with MS (EDSS: 1.5-6.0) and subjective symptoms of balance disorders. The experimental group (n = 39) received specific training to improve central integration of afferent sensory inputs; the control group (n = 41) received conventional rehabilitation (15 treatment sessions of 50 minutes each). Before, after treatment, and at one month post-treatment, patients were evaluated by a blinded rater using the Berg Balance Scale (BBS), Activities-specific Balance Confidence Scale (ABC), Multiple Sclerosis Quality of Life-54, Fatigue Severity Scale (FSS), number of falls and the Sensory Organization Balance Test (SOT). The experimental training program produced greater improvements than the control group training on the BBS (p < 0.001), the FSS (p < 0.002), number of falls (p = 0.002) and SOT (p < 0.05). Specific training to improve central integration of afferent sensory inputs may ameliorate balance disorders in patients with MS. Clinical Trial Registration (NCT01040117). © The Author(s), 2015.

Traumatic brain injury (TBI) is a major cause of disability and death globally. Despite significant progress in neuromonitoring and neuroprotection, pharmacological interventions have failed to generate favorable results. We examined the effect of memantine on serum levels of neuron-specific enolase (NSE), a marker of neuronal damage, and the Glasgow Coma Scale (GCS) in patients with moderate TBI. Patients were randomly assigned to the control group (who received standard TBI management) and the treatment group (who, alongside their standard management, received enteral memantine 30 mg twice daily for 7 days). Patients' clinical data, GCS, findings of head computed tomography, and serum NSE levels were collected during the study. Forty-one patients were randomized into the control and treatment groups, 19 and 22 patients respectively. Baseline characteristics and serum NSE levels were not significantly different between the 2 groups. The mean serum NSE levels for the memantine and the control groups on day 3 were 7.95 ± 2.86 and 12.33 ± 7.09 ng/mL, respectively (P = .05), and on day 7 were 5.03 ± 3.25 and 10.04 ± 5.72 ng/mL, respectively (P = .003). The mean GCS on day 3 was 12.3 ± 2.0 and 10.9 ± 1.9 in the memantine and control groups, respectively (P = .03). Serum NSE levels and GCS changes were negatively correlated (r = -0.368, P = .02). Patients with moderate TBI who received memantine had significantly reduced serum NSE levels by day 7 and marked improvement in their GCS scores on day 3 of the study. © 2017, The American College of Clinical Pharmacology.

The aims of the study were to detect the frequency of involvement of the Achilles tendon and plantar fascia in patients with calcium pyrophosphate deposition disease (CPPD) by high-frequency gray-scale ultrasonography (US) and power Doppler sonography (PDS) and to correlate these findings with demographic and clinical data. Two groups of patients were enrolled: group I (38 patients with CPPD) and group II (22 patients with knee OA). US/PDS examination of the heels was performed to both groups. In the CPPD group, US/PDS examination of the Achilles tendon revealed: calcification in 57.9%, enthesophytosis in 57.9%, enthesopathy in 23.7%, vascular sign in 21%, bursitis in 13.2%, and cortical bone irregularity in 10.5%. US/PDS examination of plantar fascia in the CPPD group revealed: calcification in 15.8%, cortical bone irregularity in 78.9%, enthesophytosis in 60.5%, and planter fasciitis in 42.1%. In patients with CPPD, age was significantly correlated with enthesophytosis and deep retrocalcaneal bursitis (p = 0.01 and p = 0.04, respectively). Heel tenderness and posterior talalgia were significantly correlated with Achilles tendon enthesopathy, vascular sign, and deep retrocalcaneal bursitis (p = 0.0001 for each). Inferior talalgia was significantly correlated with plantar fasciitis (p = 0.0001). The sensitivity of ultrasonography for detection of calcifications in Achilles tendon and plantar fascia was 57.9% and 15.8%, respectively, and the specificity was 100% for both. To conclude, ultrasonographic Achilles tendon and plantar fascia calcifications are frequent findings in patients with CPPD. These calcifications have a high specificity and can be used as a useful indirect sign of CPPD.

To assess the prognostic value of new Gleason grade grouping system in high-risk prostate cancer patients, we compared oncological outcomes after radical prostatectomy for patients with Gleason score 8 versus 9-10. Between 1987 and 2008, 3,755 men underwent radical prostatectomy with curative intent at University of Southern California. Patients who had Gleason score 8-10 at final histopathological evaluation (pT2-4N0) were included in this study. Eligible patients were divided into two groups; 226 with Gleason score 8 and 132 with Gleason score 9-10. Various patient and disease characteristics as well as oncological outcomes (biochemical recurrence, clinical recurrence, and overall survival) were compared between the groups. Impact of Gleason score on outcomes was controlled for preoperative prostate specific antigen, pathological stage, use of adjuvant radiotherapy, and neoadjuvant/adjuvant hormone therapy in multivariable analyses. A total of 358 patients (mean age: 65 years) were included in the analysis. Mean age and median duration of follow-up (9.6 years) were comparable between the study groups. Gleason 9-10 prostate cancer was associated with worse biochemical (HR 1.6; 95%CI [1.1-2.3]) and clinical recurrence free survival (HR = 1.9; 95%CI [1.1-3.3]); however, overall survival did not differ significantly between the groups. In addition, more patients with Gleason score 9-10 received adjuvant hormone therapy in the course of disease. Long-term follow-up after radical prostatectomy revealed significant differences in disease-specific outcomes between patients with Gleason score 8 versus 9-10. This sub-classification of high-risk patients might be helpful for patient counseling and determining therapeutic strategies.

Self-reflection and set-shifting mediate awareness in cognitively preserved schizophrenia patients.

Poor insight in schizophrenia has been linked to poor cognitive functioning, psychological processes such as denial, or more recently with impaired metacognitive capacity. Few studies, however, have investigated the potential co-dependency of multiple factors in determining level of insight, but such a model is necessary in order to account for patients with good cognitive functioning who have very poor awareness. As evidence suggests that set-shifting and cognitive insight (self-reflection (SR) and self-certainty) are strong predictors of awareness we proposed that these factors are key mediators in the relationship between cognition and awareness. We hypothesised that deficits specifically in SR and set-shifting determine level of awareness in the context of good cognition. Thirty schizophrenia patients were stratified by high and low awareness of illness and executive functioning scores. Cognitive insight, cognition, mood and symptom measures were compared between sub-groups. A low insight/high executive functioning (LI-HE) group, a high insight/high executive functioning (HI-HE) group and a low insight/low executive functioning (LI-LE) group were revealed. As anticipated, the LI-HE patients showed significantly lower capacity for SR and set-shifting than the HI-HE patients. This study indicates that good cognitive functioning is necessary but not sufficient for good awareness; good awareness specifically demands preserved capacity to self-reflect and shift-set. Results support Nelson and Narens' [1990. Metamemory: A theoretical framework and new findings. The Psychology of Learning and Motivation, 26, 125-173] model of metacognition by which awareness is founded on control (set-shifting) and monitoring (SR) processes. These specific factors could be targeted to improve insight in patients with otherwise unimpaired cognitive function.

To evaluate the efficacy of a specific rehabilitation program for patients in whom ultrasound-guided percutaneous treatment (UGPT) was performed for rotator cuff calcific tendinopathy (RCCT). In this prospective observational study, 86 patients (22 males and 64 females) with shoulder calcific tendinopathy treated with UGPT were enrolled. At the end of the procedure, a corticosteroid injection into the subacromial-subdeltoid bursa was performed. The patients were then asked to follow a specific rehabilitation protocol (2 times/week for 5 weeks) that focused on mobility, strength and function. At baseline and after 6 weeks, clinical parameters, visual analog scale (VAS) and Constant-Murley scale (CMS) scores and ultrasound (US) features were collected. The mean age of the patients was 48.9 ± 8.4 years and their mean BMI was 22.7 ± 2.1. Considering the whole cohort, the treatment was effective, with a significant decrease in the VAS score and an improvement in the CMS score. Thereafter, on the basis of the compliance to the rehabilitation program (by self-report), 53 and 33 patients were included in the rehabilitation group (Rehab group; performed exercises ≥2 times/week) and the No Rehab group (performed exercises <2 times/week), respectively. The comparison between the groups showed that the subjects who performed the exercises regularly had better results in terms of pain and functional recovery, and less associated diseases (e.g. adhesive bursitis and tenosynovitis of the long head of the biceps) than those who were less compliant with the program. UGPT, followed by a specific postprocedure rehabilitation program, was an effective treatment for RCCT. © 2014 S. Karger AG, Basel.

The careful education of patients with complex genetic disease is essential. However, healthcare providers often have limited time to spend providing thorough genetic education. Furthermore, the number of healthcare professionals possessing strong genetics training may be inadequate to meet increasing patient demands. Due to such constraints, several interventions have been investigated over the past decade to identify potential resources for the facilitation of this specific type of patient education. This systematic literature review of these interventions for patient education attempts to elucidate the answer to the question: is there sufficient evidence for best practice for delivering genetic information to patients with multifactorial conditions? The various interventions (CD-ROM, group counseling, video/decision aid, and miscellaneous) were analyzed in terms of quality criteria and achievement of specific outcomes and were rated according to the Stetler model for evidence based practice. Seven main outcomes were evaluated: 1. objective and subjective knowledge assessment 2. psychological measures (general anxiety, depression, stress, cancer worry) 3. satisfaction/effectiveness of intervention 4. time spent in counseling (time spent on basic genetic information vs. specific concerns) 5. decision making/intent to undergo genetic testing 6. treatment choice and value of that choice, and, finally 7. risk perception. Overall, the computer interventions resulted in more significant findings that were beneficial than any other category followed by the video category, although the group and miscellaneous categories did not measure all of the outcomes reported by the other two categories. Nevertheless, while these groups had neutral or negative findings in some of the outcomes, the computer intervention group showed significant improvement in genetics knowledge, psychological measures, satisfaction/effectiveness, time spent with counselor, and decision/intent to undergo testing.

We aimed to evaluate whether mean platelet volume (MPV) and platelet distribution width (PDW) are helpful to identify complete thrombus resolution (CTR) after acute deep venous thrombosis (DVT). Patients who had first-time episode of acute proximal DVT were included in this retrospective study. 100 patients with DVT were divided into two groups according to absence (group 1; n = 68) or presence (group 2; n = 32) of CTR on doppler ultrasonography at month 6. There were no significant difference in admission MPV and PDW levels between group 1 and group 2. MPV (p = 0.03) and PDW (p < 0.001) levels at month 6 were significantly higher in group 1 than in group 2. CTR showed a moderate negative correlation with PDW at month 6 (ρ = -0.47) and a weak negative correlation with MPV at month 6 (ρ = -0.26). Logistic regression analysis showed that PDW (OR, 2.2; p = 0.004) at month 6 was an independent risk factor for the presence of residual venous thrombosis in DVT patients. Receiver operating characteristics analysis revealed that a 8.4 % decrease in admission MPV at month 6 provided 62 % sensitivity and 62 % specificity (AUC: 0.64) and a 15.4 % decrease in admission PDW at month 6 provided 87 % sensitivity and 94 % specificity (AUC: 0.89) for prediction of CTR in DVT patients. Percent change in admission MPV and PDW levels at month 6 may be used to identify the patients with CTR after a first episode of acute proximal DVT.

The objective of this study was to compare the prognostic effect of time to prostate-specific antigen (PSA) nadir (TTPN) after treatment with abiraterone acetate (AA) and enzalutamide (Enz) in patients with docetaxel-naïve, metastatic castration-resistant prostate cancer (mCRPC). This study included a total of 297 consecutive patients with mCRPC, of whom 125 and 172 received AA and Enz, respectively, without previous treatment with docetaxel and subsequently achieved any degree of PSA reduction after the administration of either agent. The mean values of TTPN in the AA and Enz groups were 19 and 14 weeks, respectively. Despite the lack of significant differences in several parameters according to the mean TTPN in the Enz group, patients with TTPN>19 weeks were characterized by longer duration of androgen deprivation therapy, better performance status, lower incidence of bone metastasis, lower value of nadir PSA, and higher incidence of PSA response than those with TTPN ≤19 weeks in the AA group. The PSA progression-free survival (PFS) in patients with TTPN >19 weeks was significantly superior when compared with TTPN ≤19 weeks in the AA group; however, there was no significant effect of the mean TTPN on the PSA-PFS in the Enz group. Furthermore, TTPN was identified as one of the independent predictors of PSA-PFS in the AA group but not in Enz group. A longer time to reach a PSA nadir after treatment with AA, but not Enz, appeared to be associated with favorable disease control in patients with docetaxel-naïve mCRPC.

Obese and type 2 diabetic patients present metabolic disturbance-related alterations in nonspecific immunity, to which the decrease in their plasma arginine contributes. Although diabetes-specific formulas have been developed, they have never been tested in the context of an acute infectious situation as can be seen in intensive care unit patients. Our aim was to investigate the effects of a diabetes-specific diet enriched or not with arginine in a model of infectious stress in a diabetes and obesity situation. As a large intake of arginine may be deleterious, this amino acid was given in graded fashion. Randomized, controlled experimental study. University research laboratory. Zucker diabetic fatty rats. Gastrostomized Zucker diabetic fatty rats were submitted to intraperitoneal lipopolysaccharide administration and fed for 7 days with either a diabetes-specific enteral nutrition without (G group, n=7) or with graded arginine supply (1-5 g/kg/day) (GA group, n=7) or a standard enteral nutrition (HP group, n=10). Survival rate was better in G and GA groups than in the HP group. On day 7, plasma insulin to glucose ratio tended to be lower in the same G and GA groups. Macrophage tumor necrosis factor-α (G: 5.0±1.1 ng/2×10⁶ cells·hr⁻¹; GA: 3.7±0.8 ng/2×10⁶ cells·hr⁻¹; and HP: 1.7±0.6 ng/2×10⁶ cells·hr⁻¹; p<.05 G vs. HP) and nitric oxide (G: 4.5±1.1 ng/2×10⁶ cells·hr⁻¹; GA: 5.1±1.0 ng/2×10⁶ cells·hr⁻¹; and HP: 1.0±0.5 nmol/2×10⁶ cells·hr⁻¹; p<.05 G and GA vs. HP) productions were higher in the G and GA groups compared to the HP group. Macrophages from the G and GA groups exhibited increased arginine consumption. In diabetic obese and endotoxemic rats, a diabetes-specific formula leads to a lower mortality, a decreased insulin resistance, and an improvement in peritoneal macrophage function. Arginine supplementation has no additional effect. These data support the use of such disease-specific diets in critically ill diabetic and obese patients.

The purpose of this study is to develop a method for estimating patient-specific dose from abdomen-pelvis CT examinations and to investigate dose variation across patients in the same weight group. Our study consisted of seven pediatric patients in the same weight/protocol group, for whom full-body computer models were previously created based on the patients' CT data obtained for clinical indications. Organ and effective dose of these patients from an abdomen-pelvis scan protocol (LightSpeed VCT scanner, 120-kVp, 85-90 mA, 0.4-s gantry rotation period, 1.375-pitch, 40-mm beam collimation, and small body scan field-of-view) was calculated using a Monte Carlo program previously developed and validated for the same CT system. The seven patients had effective dose of 2.4-2.8 mSv, corresponding to normalized effective dose of 6.6-8.3 mSv/100mAs (coefficient of variation: 7.6%). Dose variations across the patients were small for large organs in the scan coverage (mean: 6.6%; range: 4.9%-9.2%), larger for small organs in the scan coverage (mean: 10.3%; range: 1.4%-15.6%), and the largest for organs partially or completely outside the scan coverage (mean: 14.8%; range: 5.7%-27.7%). Normalized effective dose correlated strongly with body weight (correlation coefficient: r = -0.94). Normalized dose to the kidney and the adrenal gland correlated strongly with mid-liver equivalent diameter (kidney: r = -0.97; adrenal glands: r = -0.98). Normalized dose to the small intestine correlated strongly with mid-intestine equivalent diameter (r = -0.97). These strong correlations suggest that patient-specific dose may be estimated for any other child in the same size group who undergoes the abdomen-pelvis scan.

Background Currently, no data are available on the prevalence of red blood cell (RBC) antibody formation amongst Kenyan patients with multiple transfusion needs, such as patients with sickle cell disease (SCD) or haematological malignancies (HM) and solid (SM) malignancies. Objectives We determined the prevalence and specificities of RBC alloantibodies and autoantibodies in two patient groups with recurrent transfusion demands at Kenyatta National Hospital, Nairobi, Kenya. Method Between February and August 2014, 300 samples from SCD, HM and SM patients were collected and screened for alloantibodies. Samples from 51 healthy blood donors were screened for irregular antibodies and phenotyped. Results Amongst the 228 patients with viable samples (SCD, n = 137; HM, n = 48; SM, n = 43), the median transfusion frequency was two to three events per group, 38 (16.7%) were RBC immunised and 32 (14.0%) had a positive direct antiglobulin test. We identified specific alloantibodies in six patients (2.6%). Four of these six were SCD patients (2.9%) who had specific RBC alloantibodies (anti-Cw, anti-M, anti-Cob, anti-S); amongst HM patients one had anti-K and one had anti-Lea. RBC autoantibody prevalence was 3.1% (7/228). Amongst the healthy blood donors, the Ror, ccD.ee and R2r, ccD.Ee phenotypes accounted for 82% of the Rhesus phenotypes and all were Kell negative. Conclusion The numbers of transfusions and the rates of RBC alloantibodies are low and the most important RBC alloantibody-inducing blood group antigens are relatively homogeneously distributed in this population. A general change in the Kenyatta National Hospital pre-transfusion test regimen is thus not necessary. The current transfusion practice should be reconsidered if transfusion frequencies increase in the future. PMID:28879098

Writer's cramp is a specific focal hand dystonia causing abnormal posturing and tremor in the upper limb. The most popular medical intervention, botulinum neurotoxin type A (BoNT-A) therapy, is variably effective for 50-70% of patients. BoNT-A non-responders undergo ineffective treatment and may experience significant side effects. Various assessments have been used to determine response prediction to BoNT-A, but not in the same population of patients. A comprehensive assessment was employed to measure various symptom aspects. Clinical scales, full upper-limb kinematic measures, self-report, and task performance measures were assessed for nine writer's cramp patients at baseline. Patients received two BoNT-A injections then were classified as responders or non-responders based on a quantified self-report measure. Baseline scores were compared between groups, across all measures, to determine which scores predicted a positive BoNT-A response. Five of nine patients were responders. No kinematic measures were predictably different between groups. Analyses revealed three features that predicted a favorable response and separated the two groups: higher than average cramp severity and cramp frequency, and below average cramp latency. Non-kinematic measures appear to be superior in making such predictions. Specifically, measures of cramp severity, frequency, and latency during performance of a specific set of writing and drawing tasks were predictive factors. Since kinematic was not used to determine the injection pattern and the injections were visually guided, it may still be possible to use individual patient kinematics for better outcomes.

[Contribution of nutritional support to fight cancer cachexia].

To increase dietary intake and to fight anorexia several measures to treat symptoms and administer the most adequate diet according to composition, texture and flavour are proposed. However, in the anorexia-caquexia present in cancer patients not always these measures are effective. Now a day it seems more reasonable to approach this problem with different strategies directed to modulate the pathologic alterations associated. The analysis of specific nutritional support as part as the treatment of these patients from a systematic review conclude that no high methodological quality studies to analyze the impact of oral supplementation on a specific group of patients, neither the study of functional effects are done. However, an increase in the total energy intake, not maintained over the time, was observed. The effects on weight and corporal composition are variable, with small differences between groups with o without supplementation and confuse due to, mainly, the heterogeneity of the patients included in the different studies analyzed. The analysis of the effects of nutritional supplements administered by enteral feeding shown an increase in the energy intake with an increase in body weight or a lack of decrease it, and with some functional and clinical beneficial effects. Despite the results and conclusions obtained, a strong recommendation to conduct clinical trials in specific group of cancer patients with different antineoplasic treatment seems necessary. N-3 fatty acids, especially eicosapentaenoic acid may have anticachectic properties. Although further trials are necessary the limited results available suggests that nutritional supplements enriched with EPA may reverse cachexia in cancer patients.

There is a lack of diagnostic tests for leptospirosis in technology-restricted settings. We developed loop-mediated isothermal amplification (LAMP) specific for the 16S ribosomal RNA gene (rrs) of pathogenic and intermediate group Leptospira species. The lower limit of detection was 10 genomic equivalents/reaction, and analytical specificity was high; we observed positive reactions for pathogenic/intermediate groups and negative reactions for non-pathogenic Leptospira species and other bacterial species. We evaluated this assay in Thailand by using a case–control study of 133 patients with laboratory-proven leptospirosis and 133 patients with other febrile illnesses. Using admission blood, we found that the rrs LAMP showed positive results in 58 of 133 cases (diagnostic sensitivity = 43.6, 95% confidence interval [CI] = 35.0–52.5) and in 22 of 133 controls (diagnostic specificity = 83.5, 95% CI = 76.0–89.3). Sensitivity was high for 39 patients who were culture positive for Leptospira spp. (84.6, 95% CI = 69.5–94.1). The rrs LAMP can provide an admission diagnosis in approximately half of patients with leptospirosis, but its clinical utility is reduced by a lower specificity. PMID:21460019

The theory of self-efficacy states that specific efficacy expectations affect behaviour. Two types of efficacy expectations are described within the theory. Self-efficacy expectations are the beliefs in the capacity to perform a specific behaviour. Outcome expectations are the beliefs that carrying out a specific behaviour will lead to a desired outcome. To develop and examine the reliability and validity of an outcome expectancy scale for self-care (OESS) among periodontal disease patients. A 34-item scale was tested on 101 patients at a dental clinic. Accuracy was improved by item analysis, and internal consistency and test-retest stability were investigated. Concurrent validity was tested by examining associations of the OESS score with the self-efficacy scale for self-care (SESS) score and plaque index score. Construct validity was examined by comparing OESS scores between periodontal patients at initial visit (group 1) and those continuing maintenance care (group 2). Item analysis identified 13 items for the OESS. Factor analysis extracted three factors: social-, oral- and self-evaluative outcome expectancy. Cronbach's alpha coefficient for the OESS was 0.90. A significant association was observed between test and retest scores, and between the OESS and SESS and plaque index scores. Further, group 2 had a significantly higher mean OESS score than group 1. We developed a 13-item OESS with high reliability and validity which may be used to assess outcome expectancy for self-care. A patient's psychological condition with regard to behaviour and affective status can be accurately evaluated using the OESS with SESS. © 2011 Blackwell Publishing Ltd.

Common and unique gray matter correlates of episodic memory dysfunction in frontotemporal dementia and Alzheimer's disease.

Conflicting evidence exists regarding the integrity of episodic memory in the behavioral variant of frontotemporal dementia (bvFTD). Recent converging evidence suggests that episodic memory in progressive cases of bvFTD is compromised to the same extent as in Alzheimer's disease (AD). The underlying neural substrates of these episodic memory deficits, however, likely differ contingent on dementia type. In this study we sought to elucidate the neural substrates of episodic memory performance, across recall and recognition tasks, in both patient groups using voxel-based morphometry (VBM) analyses. We predicted that episodic memory dysfunction would be apparent in both patient groups but would relate to divergent patterns of neural atrophy specific to each dementia type. We assessed episodic memory, across verbal and visual domains, in 19 bvFTD, 18 AD patients, and 19 age- and education-matched controls. Behaviorally, patient groups were indistinguishable for immediate and delayed recall, across verbal and visual domains. Whole-brain VBM analyses revealed regions commonly implicated in episodic retrieval across groups, namely the right temporal pole, right frontal lobe, left paracingulate gyrus, and right anterior hippocampus. Divergent neural networks specific to each group were also identified. Whereas a widespread network including posterior regions such as the posterior cingulate cortex, parietal and occipital cortices was exclusively implicated in AD, the frontal and anterior temporal lobes underpinned the episodic memory deficits in bvFTD. Our results point to distinct neural changes underlying episodic memory decline specific to each dementia syndrome. Copyright © 2013 Wiley Periodicals, Inc.

Recent investigations have shown improved patient reported outcome after preservation of the inferior mesenteric artery in sigmoid resection for diverticular disease. We report on our experience with preservation of the superior rectal artery (SRA). This is an observational single center study in a high-volume, level II inner city hospital from 2006 to 2008. Inclusion criteria were all patients with diverticular disease. Exclusion criteria were stoma formation, cancer, and iatrogenic perforation. Patients were investigated in group A with preservation of the SRA, and group B ligation of the SRA. Outcomes assessed, included incidence of anastomotic breakdown, intraoperative complications, hospital stay, and risk factors. The patient population included 259 patients, 46 patients were excluded, leaving 100 patients in group A and 113 patients in group B. Patients in both groups were comparable regarding age, gender, co-morbidities and stage of disease. Anastomotic breakdown occurred in one patient in group A and in eight patients in group B (p = 0.038). Incidence of intraoperative bleeding, wound dehiscence, and length of stay was increased in group B (p < 0.03; p < 0.04; p = 0.05). Obesity was an independent risk factor for anastomotic dehiscence in group B (p < 0.04). Our data comprise the largest patient population reported so far on vascular preservation in surgery for diverticular disease. The results of this study support the establishment of evidence based recommendations on the level of dissection in diverticular disease. Specifically obese patients are at risk of anastomotic breakdown with ligation of the SRA. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

Medulloblastoma comprises four distinct molecular subgroups: WNT, SHH, Group 3, and Group 4. Current medulloblastoma protocols stratify patients based on clinical features: patient age, metastatic stage, extent of resection, and histologic variant. Stark prognostic and genetic differences among the four subgroups suggest that subgroup-specific molecular biomarkers could improve patient prognostication. Molecular biomarkers were identified from a discovery set of 673 medulloblastomas from 43 cities around the world. Combined risk stratification models were designed based on clinical and cytogenetic biomarkers identified by multivariable Cox proportional hazards analyses. Identified biomarkers were tested using fluorescent in situ hybridization (FISH) on a nonoverlapping medulloblastoma tissue microarray (n = 453), with subsequent validation of the risk stratification models. Subgroup information improves the predictive accuracy of a multivariable survival model compared with clinical biomarkers alone. Most previously published cytogenetic biomarkers are only prognostic within a single medulloblastoma subgroup. Profiling six FISH biomarkers (GLI2, MYC, chromosome 11 [chr11], chr14, 17p, and 17q) on formalin-fixed paraffin-embedded tissues, we can reliably and reproducibly identify very low-risk and very high-risk patients within SHH, Group 3, and Group 4 medulloblastomas. Combining subgroup and cytogenetic biomarkers with established clinical biomarkers substantially improves patient prognostication, even in the context of heterogeneous clinical therapies. The prognostic significance of most molecular biomarkers is restricted to a specific subgroup. We have identified a small panel of cytogenetic biomarkers that reliably identifies very high-risk and very low-risk groups of patients, making it an excellent tool for selecting patients for therapy intensification and therapy de-escalation in future clinical trials.

Emotion dysregulation is a core feature of borderline personality disorder (BPD). So far, many studies have tested the consequences of the implementation of certain emotion regulation (ER) strategies, but there have been no investigations about ER choices in BPD. Thus, the aim of this study was to investigate habitual ER choices by self-report questionnaires and experimentally by testing the preference to select between distraction and reappraisal when facing different emotional intensities (high vs. low) and contents (borderline-specific vs. unspecific negative) in patients with BPD (n=24) compared with clinical controls (patients with major depression, n=19) and a healthy control group (n=32). Additionally, heart rate (HR) responses were continuously assessed. Main results revealed that both patient groups showed maladaptive self-reported ER choice profiles compared with HC. We found, however, no differences between the groups in the choice of distraction and reappraisal on the behavioral level and in HR responses. In BPD, within-group analyses revealed a positive correlation between symptom severity and the preference for distraction under high-intensity borderline-specific stimuli. Our findings provide preliminary evidence of ER choices in BPD and show the robustness of the choice effect in patients with affective disorders. Copyright © 2016 Elsevier Ireland Ltd.

To assess serum procalcitonin (PCT), a marker of monocyte activity, in predicting chorioamnionitis in preterm premature rupture of membranes (PPROM). Prospective cohort study in singleton gestation patients with PPROM between 2 2 + 0 to 3 3 + 6 weeks gestation. Two blood samples were taken - admission and delivery or diagnosis of clinical chorioamnionitis. Maternal serum PCT > 0.1 ng/mL was considered positive. Patients were divided into four groups: clinical evidence of chorioamnionitis confirmed by placental pathology (group C + P); pathological evidence of chorioamnionitis without clinical signs (group P); clinical signs only (group C); and patients without clinical or pathological findings (group N). Groups were compared to gestational age matched controls. Forty eight patients recruited, with 28 eligible for analysis: 10 in C + P group, 10 P group, 3 C group, and 5 N group. None of the control or PPROM patients had positive PCT on admission. At delivery, 3 of 10 group C + P and 4 of 10 group P had positive PCT. Maternal serum PCT sensitivity was 50% and specificity 55.6% for diagnosis of pathological chorioamnionitis. Maternal serum PCT is not detectable in PPROM patients at admission or in uncomplicated pregnant controls and is a poor predictor for clinical or pathological chorioamnionitis.

Objective This study investigated the impact of marital status on cancer-caused specific mortality among acute myeloid leukemia (AML) patients in the United States. Methods We used the Surveillance, Epidemiology and End Results program to identify 50,825 patients who had their clinical and follow-up information available and were diagnosed for AML between the years 1988 and 2015. The univariate and multivariable Cox regression models were used to analyze the patient data, and to minimize the group differences due to covariates between groups, a 1:1 propensity score matching was used in subsequent subgroup analysis. Results Our study demonstrated that married patients were less likely to die due to AML after adjusting for demographic and clinicopathological variables, than patients with variable unmarried status. Further analysis indicated that widowed, divorced and never married status correlated with poor cancer-cause specific survival than being married in almost all subgroups after being adjusted for the aforementioned variables (P<0.05). However, the difference between married and separated was not apparent. Moreover, similar survival analysis results were also observed in the 1:1 matched subgroups of marital status, but they displayed varied prognostic factors between them. The association of survival benefit with marriage in AML was consistent with the published survival benefit of conventional therapeutic approaches. Conclusion Overall, our study concluded that unmarried AML patients were at greater risk of cancer-specific mortality than married, and thus indicated that physicians should focus on health care strategies that target social support, in order to reduce the cancer-specific mortality in unmarried patients.

To validate the American College of Rheumatology Classification (ACR) Criteria (2012) for the diagnosis of primary Sjogren's syndrome in Chinese patients. All patients involved in this study came from the Department of Oral Medicine Peking University Stomatology Hospital. They were devided into two groups of pSS and non-pSS according to the diagnoses made by two experts. Both groups of the patients had completed medical records kept in the hospital. A total of 239 pSS patients (160 with labial salivary gland biopsy, and 79 without biopsy) and 52 age-matched non-pSS patients [(55.17±14.295),and (55.90±13.38) years old, P>0.05] (9 with biopsy, and 43 without biopsy) were involved in this study. The sensitivity and specificity of ACR criteria in diagnosing pSS were 90.37 % and 88.46 % respectively. The positive and negative likelihood ratios were 7.83 and 0.109, respectively. The sensitivities of ACR criteria in diagnosing pSS patients with and without labial biopsy were 88.75% and 93.67 %, respectively, with specificities of 88.89% and 88.37%, respectively. The most sensitive item adopted in ACR criteria was the ocular staining score with a sensitivity of 85.77%, and the most specific item was the labial salivary gland biopsy, with a specificity of 88.89%. The sensitivity and specificity of ACR criteria in diagnosing Chinese pSS patients were relatively high, and may serve as the diagnosis criteria in research and clinical practice. However, the ACR criteria need to be validated and further revised in the future .

Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF.

Urinary prostate-specific antigen (uPSA) can be used as additional parameter of benign prostatic hyperplasia (BPH) progression. From January 2001 to December 2011, uPSA was determined in 265 patients with benign prostate. Based on total prostate volume (TPV), the patients with benign prostate were divided in two groups: TPV < 31 mL and TPV ≥ 31 mL. Additional three groups were formed upon MTOPS study criteria: non- progressive BPH group (TPV < 31 mL, PSA < 1.6 ng/mL, age < 62 yrs), intermediate group (one, or two parameters {TPV, PSA, age} increased) and progressive BPH group (TPV ≥ 31 ml, PSA ≥ 1.6 ng/mL, age ≥ 62 yrs). Average uPSA values in the groups TPV < 31 mL and TPV ≥ 31 mL were 119.3 ± 124.5 and 255.5 ± 204.9 ng/mL, respectively and they were significantly different (p < 0.0001). Average uPSA values in the non- progressive BPH group, intermediate group and progressive BPH group were 86.8 ± 82.4 ng/mL, 166.6 ± 164.9 ng/mL and 274.9 ± 208.3 ng/mL, respectively and they were significantly different (p < 0.0001). The level of uPSA correlated significantly with TPV (r = 0.32, p < 0.0001). The cut off uPSA level of 150 ng/mL discriminates the patients with non-progressive BPH and progressive BPH with specificity of 0.83 and sensitivity of 0.67. The level of uPSA reflects prostatic hormonal activity and correlates with TPV, PSA and age. UPSA level ≥ 150 ng/mL can be used as additional predictive parameter of BPH progression.

Tools to collect patient-reported outcome measures (PROMs) are frequently used in the healthcare setting to collect information that is most meaningful to patients. Due to discordance among how patients and healthcare providers rank symptoms that are considered most meaningful to the patient, engagement of patients in the development of PROMs is extremely important. This review aimed to identify studies that described how patients are involved in the item generation stage of cancer-specific PROM tools developed for cancer patients. A literature search was conducted using keywords relevant to PROMs, cancer, and patient engagement. A manual search of relevant reference lists was also conducted. Inclusion criteria stipulated that publications must describe patient engagement in the item generation stage of development of cancer-specific PROM tools. Results were excluded if they were duplicate findings or non-English. The initial search yielded 230 publications. After removal of duplicates and review of publications, 6 were deemed relevant. Fourteen additional publications were retrieved through a manual search of references from relevant publications. A total of 13 unique PROM tools that included patient input in item generation were identified. The most common method of patient engagement was through qualitative interviews or focus groups. Despite recommendations from international groups and the emphasized importance of incorporating patient feedback in all stages of development of PROMs, few unique tools have incorporated patient input in item generation of cancer-specific tools. Moving forward, a framework of best practices on how to best engage patients in developing PROMs is warranted to support high-quality patient-centered care.

In adults, unexplained left ventricular hypertrophy is usually due to sarcomeric hypertrophic cardiomyopathy (HCM). Fabry disease (FD) is rare but may mimic sarcomeric HCM, and has an adverse prognosis in the absence of specific treatment. We aimed to assess cardiologists' awareness of FD based on data from the Portuguese Registry of Hypertrophic Cardiomyopathy. A total of 811 index patients, aged 55 ± 16 years, 486 (59.9%) male, were included. Three groups were characterized: A - 128 patients, 74 (57.8%) male, with pathogenic or likely pathogenic mutation(s) in sarcomeric genes; B - 234 patients, 146 (62.4%) male, with negative genetic testing; and C - 449 patients, 266 (59.2%) male, no genetic testing performed. The groups were compared in terms of whether FD was excluded in the registry. Potential red flags for FD were also analyzed and compared between groups. Patients in group A were younger and more frequently had familial HCM (A - 53.9% vs. B - 20.1% vs. C - 18.3%; p <0.001). FD was recorded as excluded in 217 (26.8%), similar in all groups; GLA gene testing was performed in only 50/217 patients (A - 48.6%, B - 25.7%, p = 0.019; C - 13.4%, p = 0.036 for B vs. C), mostly in women (p <0.001) in groups B and C. Alpha-galactosidase A (α-Gal A) activity was assessed in 39/217 (18%) patients, with no difference between groups, but more often in men (p = 0.005). Among patients with potential red flags for FD, only 46.7% underwent specific tests (GLA gene testing and/or α-Gal A activity). When GLA genotyping was performed no mutations were identified. There is a need to improve cardiologists' alertness for the identification of FD among the Portuguese HCM population. Copyright © 2018 Sociedade Portuguesa de Cardiologia.

Layer-specific strain allows the assessment of the function of every layer of myocardium. To evaluate the changes of non-ST-segment elevation acute coronary syndrome(NSTE-ACS) patients with and without complex coronary artery disease(CAD) by layer-specific strain and determine if myocardial strain can identify complex CAD and assess the severity of coronary lesions as defined by Syntax score (SS). A total of 139 patients undergoing coronary angiography due to suspected NSTE-ACS were prospectively enrolled. Echocardiography was performed 1h before angiography. Global longitudinal strain (GLS), territorial longitudinal strain (TLS), global circumferential strain (GCS) and territorial circumferential strain (TCS) of the three layers of LV wall were assessed by two-dimensional (2D) speckle tracking echocardiography (STE) with layer-specific myocardial deformation quantitative analysis based on the perfusion territories of the three major coronary arteries in an 18-segment model of LV. SS was used for predicting the severity of coronary lesions in patients with complex CAD. 78 had complex CAD, 32 had 1- or 2-vessel disease and 29 had no significant coronary stenosis confirmed by coronary angiography. According to SS value, 78 complex CAD subjects were subdivided into three groups, 24 in group SS 1 (SS≤22), 26 in group SS 2 (SS 23-32) and 28 in group SS 3 (SS≥33). Compared to the other two groups without complex CAD, patients with NSTE-ACS due to complex CAD had worse function in all 3 myocardial layers assessed by GLS, TLS, GCS and TCS. Endocardial GLS and TLS (all, P<0.01) were most affected. The absolute differences between endocardial and epicardial GLS and TLS were lower in magnitude in patients with complex CAD than in those without (all, P<0.001), and the more complex of coronary lesion, the lower magnitude of the parameters(all, P<0.001). Endocardial GLS and TLS were closely correlated with SS value(r=-0.751 and r=-0.753, respectively; P<0.001). By receiver-operating characteristic curve analysis, endocardial GLS and TLS demonstrated the highest area under curve, showing better diagnostic accuracy (endocardial GLS: value<-21.35% had 72% sensitivity, 84% specificity and area under the curve ¼0.846; endocardial TLS: value<-20.15% had 72% sensitivity, 88% specificity and area under the curve ¼0.852) than GCS, TCS, mid-myocardial and epicardial GLS, and TLS(all, P<0.05). Strains, particularly endocardial GLS and TLS measurement by 2DSTE might enable a non-invasive method to identify complex CAD and predict the severity of coronary lesions in patients with NSTE-ACS.

[Patient-centered approaches to understanding, transformation and solution of team conflicts in the psychiatric clinic within the scope of the Balint group concept].

The working climate and therapeutic possibilities in a hospital are determined, among other factors, by emotional processes in everyday ward routine. Team conflicts and their solution are not infrequently reflections of the open-mindedness of a hospital towards the complexity of these processes. However, the complex interlocking of transference processes with rôle-specific and personality-conditioned behaviour patterns makes it more difficult to understand and make use of these emotional processes within the team. We present a specific attempt to working up emotional conflicts in a patient-centred approach via focussing on self-rating of the team workers in respect of mood, feeling tone and imagination. Specific internal Balint groups are the fulcrum. To distinguish this method from the theory of object-directed transference of emotions and constructions of relations, the theoretical basis of this group method is seen in the systemic paradigm with which patient-focussed solution functions are obtained in respect of process orientation and instrumental part functions of the team workers. In this connection it was explored to what extent the following factors can be interpreted as patient-induced phenomena: therapeutic and rôle behaviour, hospital structures and administrative squabbles, internal and external walls of a mental hospital.

To observe the change of PVI after thoracic epidural block on the basis of general anesthesia. In 26 patients undergoing elective upper abdominal operations, changes of SVI, PVI, SVV, PPV and CVP were monitored immediately before and 10 minutes after T8-9 thoracic epidural anesthesia on the basis of general anesthesia. The definition was that patients with ΔSVI greater than 10% belonged to response group to epidural block. Before epidural block, the PVI, SVV and PPV baseline values in patients of response group were significantly higher than those in patients of non-response group. PVI, SVV and PPV after epidural block were significantly higher than immediately before epidural block (P < 0.001). PVI, SVV and PPV baseline values immediately before epidural block were positively correlated with ΔSVI; the correlation coefficients were 0.70, 0.71 and 0.63, respectively, P ≤ 0.001. The optimal critical values for PVI, SVV and PPV to predict response to T8-9 gap epidural block under general anesthesia were 16% (sensitivity 80%, specificity 92%), 13% (sensitivity 90%, specificity 62%) and 12% (sensitivity 90%, specificity 77%), respectively. PVI can be used as a noninvasive indictor to monitor volume change after thoracic epidural block on the basis of general anesthesia.

Objective: To investigate the clinical symptoms and immunology inspection characteristics of nasal cavity local allergy. Method: Selected 60 patients as observation group, who had only nasal local allergy symptoms, allergen skin prick test and serum allergen specific IgE (SIgE) test were negative, 40 allergic rhinitis (AR) patients and 40 healthy volunteers as control groups. To detect Symptom scores and VAS scores, and eosinophilia counts in venous blood, allergen skin prick test (SPT), serum allergen SIgE test, nasal secretions allergen SIgE test, nasal mucous membrane excitation test in both observation group and AR group, eosinophilia counts in nasal secretion, taked the data for statistical analysis. Result: There was no difference ( P > 0.05) in the symptom scores and VAS scores of observation group and the AR group. The eosinophilia counts in venous blood in the AR group were higher than in the observation group ( P < 0.05). The eosinophilia counts in venous blood in the observation group were higher than in the healthy volunteers group ( P < 0.05). The positive rate of nasal secretions dust mites and pollen allergen was 90% (54/60) in observation group. There was no significant difference ( P > 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the AR group. There was significant difference ( P < 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the healthy volunteers group. There were 6 patients in observation group whose nasal secretions allergen SIgE test and nasal mucous membrane excitation test were both negative, could be diagnosised as non-allergic rhinitis (NAR). According to eosinophilia counts in venous blood and nasal secretions, 4 patients were diagnosised as vasomotor rhinitis and 2 patients were diagnosised as NAR with eosinophilia syndrome. There were 54 patients in observation group whose nasal secretions allergen SIgE test and (or) nasal mucous membrane excitation test were positive, could be diagnosised as local allergic rhinitis. After three years, all of the observation group patients were detected with SPT and serum allergen SIgE test. Five patients diagnosed as local allergic rhinitis before three years were positive. Six patients diagnosed as NAR before three years were negative. Conclusion: For patients with the typical medical history and symptoms of AR, but allergen SPT and serum allergen SIgE test were negative, there was local specific hypersensitivity in nasal mucosa, but the reaction was not accompanied by systemic sensitization. Combined with nasal secretions allergen SIgE test or allergen nasal mucosa proocation tests positive, could be diagnosed as local allergic rhinitis.

Impairment of orientation for time (OT) is a characteristic symptom of Alzheimer disease (AD). However, the brain regions underlying OT remain to be elucidated. Using single photon emission computed tomography (SPECT), we examined the brain regions exhibiting hypoperfusion that were associated with OT. We compared regional cerebral blood flow (rCBF) differences between AD and amnesic mild cognitive impairment (aMCI) or normal subjects using 3-dimensional stereotactic surface projection (3D-SSP) analysis. AD patients were divided into OT good and poor groups according to their mean OT scores, and rCBF then compared between the groups to elucidate OT-specific brain areas. 3D-SSP analysis showed reduced rCBF in the left superior parietal lobule (SPL) and bilateral inferior parietal lobule (IPL) in AD patients. In the poor OT group, 3D-SSP analysis revealed hypoperfusion in the bilateral SPL, IPL, posterior cingulated cortex (PCC), and precuneus. Among these areas, region of interest analysis revealed a significant higher number of hypoperfused pixels in the left PCC in the OT poor AD group. Our SPECT study suggested that hypoperfusion in the left SPL and bilateral IPL was AD specific, and reduced rCBF in the left PCC was specifically associated with OT.

This retrospective study presents our 4-year experience of preemptive treatment of early anti-HLA donor specific antibodies with IgA- and IgM-enriched immunoglobulins. We compared outcomes between patients with antibodies and treatment (case patients) and patients without antibodies (control patients). Records of patients transplanted at our institution between 03/2013 and 11/2017 were reviewed. The treatment protocol included one single 2g/kg immunoglobulin infusion followed by successive 0.5g/kg infusions for a maximum of 6 months, usually combined with a single dose of anti-CD20 antibody and, in case of clinical rejection or positive crossmatch, with plasmapheresis or immunoabsorption. Among the 598 transplanted patients, 128 (21%) patients formed the case group and 452 (76%) the control group. In 116 (91%) patients who completed treatment, 106 (91%) showed no antibodies at treatment end. Fourteen (13%) patients showed antibody recurrence thereafter. In case vs. control patients and at 4-year follow-up, respectively, graft survival (%) was 79 vs. 81 (p=0.59), freedom (%) from biopsy-confirmed rejection 57 vs. 53 (p=0.34) and from chronic lung allograft dysfunction 82 vs. 78 (p=0.83). After lung transplantation, patients with early donor specific antibodies and treated with IgA- and IgM-enriched immunoglobulins had 4-year graft survival similar to patients without antibodies and showed high antibody clearance.

We retrospectively evaluated the utility of 68 Ga-PSMA-11 PET for planning 223 RaCl 2 therapy of patients with metastatic prostate cancer and its impact on the therapeutic response as determined by prostate-specific antigen (PSA) and alkaline phosphatase (ALP), as well as the correlation of PSA changes with the results of prostate-specific membrane antigen (PSMA) PET follow-up scans. Methods: Sixty-three patients with a median age of 73 y who underwent 307 cycles of therapy with 223 RaCl 2 were analyzed. In 31 patients, bone scanning and radiologic imaging were performed for pretherapeutic imaging (group 1). In 32 patients, bone scanning and PSMA PET were performed before therapy (group 2). Patients with small lymph node metastases and local recurrence were not excluded from treatment, consistent with current guidelines. PSA and ALP were measured before each treatment cycle and 4 wk after the final cycle. Thirteen patients from group 2, who underwent a second PSMA PET scan as a follow-up, were evaluated to determine the significance of PSA changes as a follow-up marker. Results: In group 1, 4 patients (12.9%) showed a PSA decline, of whom 2 patients and 1 patient showed a PSA decline of more than 30% and more than 50%, respectively. In contrast, in group 2, 14 patients (43.8%) showed a PSA decline, of whom 10 and 8 patients showed a decline of more than 30% and more than 50%, respectively ( P = 0.007). Thirty-seven patients had a high ALP level (19 from group 1 and 18 from group 2). Twelve (63.2%) and 16 (88.9%) patients in groups 1 and 2, respectively, showed an ALP decline. This difference was not significant; however, 7 (36%) and 13 (72.2%) patients in groups 1 and 2, respectively, showed an ALP decline of more than 30% ( P = 0.04). Considering any ALP decline as a response, no patient with increasing ALP showed a PSA response ( P = 0.036). There was a significant correlation between the PSA changes and the therapeutic response according to follow-up PSMA PET. Conclusion: When PSMA PET is used as the gatekeeper in addition to bone scanning, radionuclide therapy with 223 Ra may be more effective and have more success regarding changes in the PSA. An increase in PSA during therapy cycles occurs because of disease progression. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

We aimed to evaluate the impact of a transition service on clinical and developmental outcomes in adolescent Inflammatory Bowel Disease (IBD) patients on transfer to adult health care services. We reviewed the records of IBD patients diagnosed in pediatric care following their transfer/attendance to the adult IBD service. The data on patients who attended the transition service were compared with those who did not pass through the transition service. Seventy-two patients were included in the study 41M and 31F. Forty-four patients went through the transition system (Group A), and 28 had no formalized transition arrangement before transfer (Group B). A significantly higher number of Group B patients needed surgery within 2 years of transfer when compared with patients in Group A (46% vs. 25%, p = .01). Sixty-one percent of patients in Group B needed at least one admission within 2 years of transfer when compared with 29% of Group A patients (p = .002). Nonattendance at clinics was higher in Group B patients with 78% having at least one nonattendance, whereas 29% of Group A failed to attend at least one appointment (p = .001). In addition, drug compliance rates were higher in the transition group when compared with Group B (89% and 46%, respectively; p = .002). A higher proportion of transitioned patients achieved their estimated maximum growth potential when completing adolescence. There was a trend toward higher dependence on opiates and smoking in Group B patients. In adolescent IBD patients, transition care is associated with better disease specific and developmental outcomes. Prospective studies of different models of transition care in IBD are needed.

To compare the clinical implications of electro-diagnostic study with those of magnetic resonance imaging in patients with lumbosacral intervertebral herniated disc or spinal stenosis. Retrospective study of clinical data. Patients with lumbosacral intervertebral herniated disc or spinal stenosis, diagnosed by clinical assessment and magnetic resonance imaging (MRI), were selected. A total of 753 patients (437 with lumbosacral intervertebral herniated disc and 316 with spinal stenosis) were included in the study. Clinical data for electrodiagnostic study (EDX)and MRI were compared and the sensitivity and specificity of these studies were evaluated. Among all subjects, 267 had radiculopathy on EDX (EDX (+)) and 486 no radiculopathy (EDX(-)). Furthermore, 391 had root compression on MRI (MRI (+)) and 362 no root compression on MRI (MRI (-)). Patients with radioculopathy on EDX (+) showed a significantly higher visual analogue scale score for radiating pain and a higher Oswestry Disability Index than those with negative findings by EDX (-) in the total subjects group and the lumbosacral intervertebral herniated disc subgroup, and there was a trend toward higher Oswestry Disability Index in the spinal stenosis subgroup. Although patients with radioculopathy on root compression on MRI (+) also had a higher visual analogue scale for radiating pain than patients with negative findings by MRI (-) in the total subjects group and the lumbosacral intervertebral herniated disc subgroup, no significant difference was seen in the Oswestry Disability Index. EDX revealed a significant correlation with muscle weakness in the total subjects group and the lumbosacral intervertebral herniated disc subgroup, and trends toward muscle weakness in the spinal stenosis subgroup, whereas there was no such significant correlation for MRI findings in any group. Electrodiagnostic study had a higher specificity in terms of physical examination data than MRI, in spite of its lower sensitivity. Electrodiagnostic study was significantly more correlated with clinical data, especially leg muscle weakness and functional status, and showed a higher specificity than MRI in patients with lumbosacral intervertebral herniated disc or spinal stenosis.

To predict the malignant potential of prostate cancer (PCa) according to prostate-specific antigen velocity (PSAV), PSA density (PSAD), free/total PSA ratio (%fPSA), and digital rectal examination (DRE). From January 2009 to December 2012, 548 adult male patients were diagnosed with PCa by prostate biopsy at four hospitals in Korea. We retrospectively analyzed 155 adult male patients with an initial PSA level≤10 ng/mL and whose PSA levels had been checked more than two times at least 6 months before they had been diagnosed with PCa, with test intervals of more than 3 months. Patients with a urinary tract infection, and patients who had previously undergone cystoscopy or surgery of the prostate were excluded. We separated patients into two groups according to Gleason sum [Gleason sum≤7 (n=134) or Gleason sum≥8 (n=21)] and the presence of extracapsular invasion [organ confined (n=129) or extracapsular invasion (n=26)]. Differences between the groups were compared. The group with a Gleason sum≥8 or extracapsular invasion of PCa showed high PSAV and significantly lower %fPSA. There were no significant differences in PSAD and the presence of an abnormality on DRE between two groups. In PCa patients treated with other therapies besides prostatectomy, a high PSA velocity and a low %fPSA may predict high grade PCa with a Gleason sum≥8 or the presence of extracapsular invasion.

Objective: To evaluate the performance of T cell enzyme-linked immuno-spot assay (T-SPOT) on peripheral blood in combination with adenosine deaminase (ADA) on pleural fluid for diagnosis of tuberculous (TB) pleurisy within different age groups. Methods: The data of patients with pleural effusion from the Department of Pulmonary and Critical Care Medicine of the First Affiliated Hospital of Wenzhou Medical University from April 2012 to November 2016 were retrospectively analyzed, and the diagnoses of these patients were histopathologically confirmed through medical thoracoscopy. The cases who had confirmed diagnosis, in the same time, received peripheral blood T-SPOT.TB were enrolled. The performance of peripheral blood T-SPOT.TB in combination with pleural fluid ADA on diagnosing TB pleurisy in the younger patients (16-59 years old) and elderly patients (≥60 years old) were analyzed respectively. The sensitivity, specificity and the receiver operating characteristic (ROC) curve were adopted for statistical analysis. Results: A total of 448 cases were finally enrolled, 341(76.1%) confirmed with TB pleurisy, 224 males, 117 females, (47±19) years old; and 107 (23.9%) classified as non-TB pleurisy, 65 males, 42 females, (61±14) years old. There were 285 cases who were classified as younger group, and the other 163 cases were classified as elderly group. The sensitivity and specificity of peripheral blood T-SPOT.TB were 85.4% (204/239) and 71.7% (33/46) in the younger patients, 76.5% (78/102) and 59.0% (36/61) respectively in the elderly patients. The sensitivity of peripheral blood T-SPOT.TB in the younger patients was significantly higher than that in the elderly patients ( P =0.047). The sensitivity and specificity were 99.2% and 95.7% in combination with peripheral blood T-SPOT.TB and pleural fluid ADA respectively in the younger patients. The area under ROC curve (AUC) of T-SPOT.TB in the younger patients was 0.833, AUC of T-SPOT.TB combined with ADA was 0.911. The combination test of 2 tests had the sensitivity of 96.1% and the specificity of 90.2% respectively in the elderly patients. The AUC of T-SPOT.TB in the elderly patients was 0.747, AUC of T-SPOT.TB combined with ADA was 0.911. Conclusion: Peripheral blood T-SPOT.TB combined with pleural fluid ADA can improve the diagnostic performance for TB pleurisy with different ages, especially for elderly patients who can't tolerate pleural biopsy.

A randomized controlled trial. To compare changes in self-rated disability, pain, and anticipatory postural adjustments between specific trunk exercise and general exercise in patients with chronic low back pain. Chronic low back pain is associated with altered motor control of the trunk muscles. The best exercise to address altered motor control is unclear. Sixty-four patients with chronic low back pain were randomly assigned to a specific trunk exercise group (SEG) that included skilled cognitive activation of the trunk muscles in addition to a number of other best practice exercises, whereas the general exercise group performed only seated cycling exercise. The training program lasted for 8 weeks. Self-rated disability and pain scores were collected before and after the training period. Electromyographic activity of various trunk muscles was recorded during performance of a rapid shoulder flexion task before and after training. Muscle onsets were calculated, and the latency time (in ms) between the onset of each trunk muscle and the anterior deltoid formed the basis of the motor control analysis. After training, disability was significantly lower in the SEG (d = 0.62, P = 0.018). Pain was reduced in both groups after training (P < 0.05), but was lower for the SEG (P < 0.05). Despite the general exercise group performing no specific trunk exercise, similar changes in trunk muscle onsets were observed in both groups after training. SEG elicited significant reductions in self-rated disability and pain, whereas similar between-group changes in trunk muscle onsets were observed. The motor control adaptation seems to reflect a strategy of improved coordination between the trunk muscles with the unilateral shoulder movement. Trunk muscle onsets during rapid limb movement do not seem to be a valid mechanism of action for specific trunk exercise rehabilitation programs.

Sleep disturbances, fantasy proneness, cognitive failures, and dissociative symptoms are related to each other. However, the co-occurrence of these phenomena has been primarily studied in non-clinical samples. We investigated the correlations between these phenomena in dissociative identity disorder (DID) patients, post-traumatic stress disorder (PTSD) patients, and healthy controls. Both patient groups reported more sleep problems and lower sleep quality and displayed higher levels of fantasy proneness and cognitive failures than controls. However, the two patient groups did not differ with regard to these variables. Moreover, a higher level of unusual sleep experiences tended to predict participants belonging to the DID group, while specifically a lower sleep quality and more cognitive failures tended to predict participants belonging to the PTSD group.

To evaluate the utility of rapid antigen detection testing (RADT) for the diagnosis of group A beta-hemolytic streptococcal tonsillopharyngitis in children, and to detect the sensitivity and specificity of rapid antigen detection of group A beta-hemolytic streptococci from throat specimen compared with throat culture. Rapid antigen detection and throat culture results for group A beta-hemolytic streptococci from outpatients attending university hospital between 1st January 2011 and 31st of December 2011 were evaluated retrospectively. The antigen test negative-throat culture positive patients were investigated for streptococcal carriage. For this purpose, the throat culture results taken from these patients were reviewed after treatment. Eight hundred and ninetytwo children were included in the studywith a mean age of 5.34 y. There were 639 and 253 children in two groups with age of 0-6 and 7-17 y, RADT sensitivity and specificity were found to be 59.5 % and 97.2 %, respectively. The positive predictive value was 87.1 %, whereas negative predictive value was 88.4 %. After treatment of 74 patients with throat culture positive and antigen test negative. Group A beta-hemolytic streptococci were isolated in 12 of them (16.2 %) and accepted as a carrier. The low sensitivity of the RADT may be related to streptococcal carriage in some patients. The throat culture should be repeated after treatment to detect streptococcal carriage.

There is a relation between deficits of the proprioceptive system and movement control dysfunction in patients with chronic low back pain (LBP) but, the exact mechanism of this relation is unknown. Exercise therapy has been recognized as an effective method for low back pain treatment. In spite of this, it is not clear which of the various exercise therapy programs lead to better results. Therefore, the present analyze the efficacy of a HUBER study aims to exercise system mediated sensorimotor training protocol on proprioceptive system, lumbar movement control (LMC) and quality of life (QOL) in patients with chronic non-specific LBP. Quasi-experimental study. 53 patients with chronic non-specific LBP (mean age 37.55 ± 6.67 years,and Body Mass Index (BMI) 22.4 ± 3.33) were selected by using Roland-Morris Disability Questionnaire (RMQ) and were assigned into two experimental (N= 27) and control groups (N= 26) The experimental group underwent a five-week (10 sessions) Sensorimotor training by using the Human Body Equalizer (HUBER) spine force under the supervision of an investigator. The movement control battery tests, the HUBER machine testing option, goniometer and visual analogue scale used for movement control, neuromuscular coordination, proprioception and LBP assessment respectively. The assessments were completed in pre-test and after five weeks. The paired and sample T tests were used for data analysis in SPSS program version 18 (Significance level were set at a P value < 0.05). The HUBER system mediated sensorimotor training demonstrated significant improvement in the proprioceptive system, LMC and QOL (P= 0.001). Also There was a significant reduction in the pain scores of subjects with chronic non-specific LBP in the sensorimotor group (P= 0.001). In this study, only the short term effects of the sensorimotor training were examined. The results suggest that a sensorimotor training program causes significant improvement in patients with chronic non-specific LBP. Future research should be carried out with a larger sample size to examine the long term effects of the sensorimotor training program on treatment of patients with chronic non-specific LBP. Considering the efficacy of the sensorimotor training, it is recommended that this intervention should be applied to treatment of patients with chronic non-specific LBP in the future.

The purpose of this study was to confirm the prevalence of medial ankle widening among patients with an isolated fibular fracture and to determine the functional outcome of nonoperative treatment despite a diagnosis of a supination-external rotation stage-IV injury based on stress radiography. One hundred and one patients with evidence of an isolated fibular fracture and an intact mortise seen on a standard ankle trauma radiograph series were evaluated with stress radiographs. Clinical signs were recorded at the time of presentation. A positive stress test was defined as > or =4 mm of widening of the medial clear space. Patients with a negative stress test were treated nonoperatively, those with a positive stress test and clinical signs of medial injury were treated surgically, and those with a positive stress test and no signs of medial injury were treated according to the preference of the surgeon and patient. The patients were followed prospectively with radiographs and ankle outcome scores. Sixty-six (65%) of the 101 patients had a positive stress radiograph. Thirty-six of them had signs of medial injury, and thirty had no medial injury. With regard to predicting a positive stress radiograph, medial tenderness had a sensitivity of 56% and a specificity of 80%, swelling had a sensitivity of 55% and a specificity of 71%, and ecchymosis had a sensitivity of 26% and a specificity of 91%. Of the subset of patients without signs of medial injury, twenty were treated nonoperatively (group I) and ten were treated operatively (group II). Two of the twenty patients in group I had evidence of persistent widening of the medial clear space at the time of the latest follow-up (mean, 7.4 months); only one of those patients was symptomatic. The average American Orthopaedic Foot and Ankle Society (AOFAS) score was 94 points in group I and 93 points in group II. We found a high rate of positive stress radiographs for patients who presented with an isolated fibular fracture and an intact ankle mortise on the initial radiographs. Medial tenderness, swelling, and ecchymosis were not sensitive with regard to predicting widening of the medial clear space on stress radiographs. All of the patients with a positive stress radiograph and no clinical symptoms who were treated without surgery had a good or excellent clinical result.

We have performed a comparative study to evaluate seasonal and perennial schedules after 3 years of immunotherapy. Sixty patients suffering from rhinitis and/or asthma due to grass pollen sensitization were randomly allocated to receive a semi-depot extract of Phleum pratense according to a perennial or seasonal schedule. The last year of the study, 14 patients were recruited as a control group without immunotherapy. The cumulative dose was 602 BU in the perennial group and 372 BU in the seasonal group. The frequency and severity of side-effects were similar and very low in both treated groups. The IgE level was significantly lower after perennial immunotherapy at the end of the first 2 years. A seasonal decrease in specific IgG levels was observed in patients who interrupted immunotherapy, while this was not observed in patients under the perennial schedule. Symptoms and medication scores did not show differences between groups. Nevertheless, we found a significant difference between treated patients and the control group.

To evaluate the prognostic significance of serially measured tissue polypeptide-specific antigen (TPS) levels in patients with metastatic prostatic carcinoma treated with intermittent maximal androgen blockade (MAB). To determine its value with respect to predicting response to treatment and time to clinical progression. Finally to compare TPS with prostate-specific antigen (PSA) measurements in terms of prognostic impact in patients with metastatic prostatic carcinoma. TPS and PSA measurements were performed before start of and monthly during intermittent MAB in 68 patients participating in EORTC protocol 30954. Both TPS and PSA were measured in serum. Fifty-six patients from eight centers were included in the final analysis because at least three TPS values were available. TPS and PSA values were correlated with clinical course of the disease. Median follow-up was 21.3 months. Three patient groups were defined on clinical grounds: (a) clinically progressive disease (n=18); (b) clinically stable disease (n=33); and (c) patients who did not reach a predefined nadir PSA value following 9 months of treatment (n=5). Pretreatment TPS was significantly higher in the clinically progressive patients than in the other patient groups (p=0.0041). When grouping patients according to their pretreatment TPS values (cut-off value of 100 U/l) the pretreatment TPS value (>100 U/l) proved to be a statistically significant prognostic factor with respect to time to progression: elevated TPS was associated with a 3.8 increased risk for progressive disease (p=0.0055). Pretreatment PSA (>100 ng/ml) was of no prognostic value for time to progression. In five patients increase of TPS coincided with or preceded clinical progression during treatment, whereas PSA remained normal. Additional value of pretreatment TPS measurements in metastatic prostate cancer patients is found in defining the patients with rapid clinical progression. Following MAB an increase in TPS signifies clinical progression even if PSA is found to remain normal.

The efficacy of NS5A inhibitors for the treatment of patients chronically infected with hepatitis C virus (HCV) can be affected by the presence of NS5A resistance-associated substitutions (RASs). We analyzed data from 35 phase I, II, and III studies in 22 countries to determine the pretreatment prevalence of various NS5A RASs, and their effect on outcomes of treatment with ledipasvir-sofosbuvir in patients with genotype 1 HCV. NS5A gene deep sequencing analysis was performed on samples from 5397 patients in Gilead clinical trials. The effect of baseline RASs on sustained virologic response (SVR) rates was assessed in the 1765 patients treated with regimens containing ledipasvir-sofosbuvir. Using a 15% cut-off, pretreatment NS5A and ledipasvir-specific RASs were detected in 13% and 8% of genotype 1a patients, respectively, and in 18% and 16% of patients with genotype 1b. Among genotype 1a treatment-naïve patients, SVR rates were 91% (42/46) vs. 99% (539/546) for those with and without ledipasvir-specific RASs, respectively. Among treatment-experienced genotype 1a patients, SVR rates were 76% (22/29) vs. 97% (409/420) for those with and without ledipasvir-specific RASs, respectively. Among treatment-naïve genotype 1b patients, SVR rates were 99% for both those with and without ledipasvir-specific RASs (71/72 vs. 331/334), and among treatment-experienced genotype 1b patients, SVR rates were 89% (41/46) vs. 98% (267/272) for those with and without ledipasvir-specific RASs, respectively. Pretreatment ledipasvir-specific RASs that were present in 8-16% of patients have an impact on treatment outcome in some patient groups, particularly treatment-experienced patients with genotype 1a HCV. The efficacy of treatments using NS5A inhibitors for patients with chronic hepatitis C virus (HCV) infection can be affected by the presence of NS5A resistance-associated substitutions (RASs). We reviewed results from 35 clinical trials where patients with genotype 1 HCV infection received treatments that included ledipasvir-sofosbuvir to determine how prevalent NS5A RASs are in patients at baseline, and found that ledipasvir-specific RASs were present in 8-16% of patients prior to treatment and had a negative impact on treatment outcome in subset of patient groups, particularly treatment-experienced patients with genotype 1a HCV.

To investigate the positive predictive value (PPV) of urinary vanillylmandelic acid (VMA) testing in the diagnosis of phaeochromocytoma and to describe the features associated with phaeochromocytoma at the University Hospital of the West Indies (UHWI). There were 551 VMA tests performed from January 2003 to June 2009 and 122 tests in 85 patients were elevated (ie > or = 35 micromol/24 hr). The study patients were categorized as: (i) 'surgical' (5 patients who underwent surgery) or (ii) 'non-surgical' (remaining 80 patients). Forty medical charts (out of 85) were reviewed using a standardized data extraction form. The median age for patients in the non-surgical group (with charts reviewed, n = 35) was 36 years (range 9-70) and the median VMA was 43 micromol/24 hr (IQR 38-51). Of these patients, 83% had one or no symptom typical of phaeochromocytoma. In the surgical group the median VMA was 58 micromol/24 hr (IQR 44-101); phaeochromocytoma was confirmed histologically in 3 patients, all of whom had several symptoms typical of catecholamine excess. VMA testing had a PPV of 8%, specificity of 79% and sensitivity of 100%. VMA testing at UHWI has poor specificity and high sensitivity. These results contrast with international data showing that VMA testing is poorly sensitive but highly specific. The use of assays with higher specificity (eg plasma or urinary metanephrines) may represent a more cost-effective approach to biochemical screening at UHWI.

Noninvasive markers of brain function could yield biomarkers in many neurological disorders. Disease models constrained by coordinate-based meta-analysis are likely to increase this yield. Here, we evaluate a thalamic model of temporal lobe epilepsy that we proposed in a coordinate-based meta-analysis and extended in a diffusion tractography study of an independent patient population. Specifically, we evaluated whether thalamic functional connectivity (resting-state fMRI-BOLD) with temporal lobe areas can predict seizure onset laterality, as established with intracranial EEG. Twenty-four lesional and non-lesional temporal lobe epilepsy patients were studied. No significant differences in functional connection strength in patient and control groups were observed with Mann-Whitney Tests (corrected for multiple comparisons). Notwithstanding the lack of group differences, individual patient difference scores (from control mean connection strength) successfully predicted seizure onset zone as shown in ROC curves: discriminant analysis (two-dimensional) predicted seizure onset zone with 85% sensitivity and 91% specificity; logistic regression (four-dimensional) achieved 86% sensitivity and 100% specificity. The strongest markers in both analyses were left thalamo-hippocampal and right thalamo-entorhinal cortex functional connection strength. Thus, this study shows that thalamic functional connections are sensitive and specific markers of seizure onset laterality in individual temporal lobe epilepsy patients. This study also advances an overall strategy for the programmatic development of neuroimaging biomarkers in clinical and genetic populations: a disease model informed by coordinate-based meta-analysis was used to anatomically constrain individual patient analyses.

A program has been developed in MATLAB for use in quality assurance of treatment planning of radiation therapy. It analyzes patient DVH files and compiles dose volume data for review, trending, comparison and analysis. Patient DVH files are exported from the Eclipse treatment planning system and saved according to treatment sites and date. Currently analysis is available for 4 treatment sites; Prostate, Prostate Bed, Lung, and Upper GI, with two functions for data report and analysis: patient-specific and organ-specific. The patient-specific function loads one patient DVH file and reports the user-specified dose volume data of organs and targets. These data can be compiled to an external file for a third party analysis. The organ-specific function extracts a requested dose volume of an organ from the DVH files of a patient group and reports the statistics over this population. A graphical user interface is utilized to select clinical sites, function and structures, and input user's requests. We have implemented this program in planning quality assurance at our center. The program has tracked the dosimetric improvement in GU sites after VMAT was implemented clinically. It has generated dose volume statistics for different groups of patients associated with technique or time range. This program allows reporting and statistical analysis of DVH files. It is an efficient tool for the planning quality control in radiation therapy. © 2012 American Association of Physicists in Medicine.

The present study was conducted to assess the seroprevalence of Toxoplasma gondii in and around Tirunelveli by in-house IgG assay using ELISA. Serum samples from 175 immunodeficient and 175 immunocompetent patients were collected at Tirunelveli district, Tamil Nadu from May 2006 to October 2007. They were subjected into in-house IgG assay using enzyme-linked immune sorbent assay (ELISA) in which tachyzoite soluble antigen derived from solubilised whole organisms was used. Out of 350 patients tested by IgG ELISA, 46 patients (13.14%) had antibodies for toxoplasmosis with mean OD value of 0.2 ± 0.073 and the OD value ranged from 0.144 to 0.444. Among the immunocompetent group of 175 patients, 19 patients (10.86%) had antibodies to toxoplasmosis whereas, in immunodeficient group of 175 patients, 27 patients (15.43%) had antibodies for toxoplasmosis. There was no statistical difference (P > 0.05) between the immunocompetent and immunodeficient group. The sensitivity and specificity of IgG ELISA in detecting toxoplasmosis was 90 and 100%, respectively. The overall seroprevalence of toxoplasmosis in and around Tirunelveli district of Tamil Nadu was 13.14% based on IgG ELISA. The study has proved ELISA to be a sensitive and specific procedure for the serodiagnosis of toxoplasmosis.

High-density lipoprotein cholesterol (HDL-C) levels are inversely related to the atherosclerotic burden and are higher in women than in men. We aimed to investigate the sex-specific relationship between serum HDL-C levels and the Duke treadmill score (DTS) in this study. A total of 111 patients (59 men, 42 women) with suspected coronary artery disease (CAD) who underwent exercise treadmill test (EST) were included. Fasting blood samples were obtained for the assessment of serum lipid levels. DTS was calculated for each patient based on EST findings including ST segment deviation and symptoms. Patients were categorized into a moderate to high risk group based on the DTS score (group-I: 38 patients) and a low risk group (group-II: 63 patients). There was a significant positive correlation between serum HDL-C levels and DTS (r = 0.230; P=0.021). The mean HDL-C level was significantly higher in group-II relative to group-I (49.25 ±11.21 vs. 44.43 ± 11.18, respectively, P = 0.04). An HDL-C level less than the cut-off value of 41.39 mg/dL predicted a moderate to severe risk DTS with 65% sensitivity and 69% specificity in men (area under curve = 0.732, P = 0.004), but not in women (area under curve = 0.505, P = 0.958). After adjustment for traditional CAD risk factors (age, sex, and smoking status), the relationship of DTS to HDL-C remained significant. (P = 0.030; adjusted OR = 0.948 [95% CI, 0.904-0.995]). Low HDL-C levels may be associated with a moderate to high risk Duke treadmill score in men, but not in women. Further research is required to clarify the sex-specific relationship between HDL-C and DTS.

High-load strength training consisted of unilateral heel raises with a towel inserted under the toes. Primary outcome was the foot function index (FFI) at 3 months. Additional follow-ups were performed at 1, 6, and 12 months. At the primary endpoint, at 3 months, the strength group had a FFI that was 29 points lower [95% confidence interval (CI): 6-52, P = 0.016] compared with the stretch group. At 1, 6, and 12 months, there were no differences between groups (P > 0.34). At 12 months, the FFI was 22 points (95% CI: 9-36) in the strength group and 16 points (95% CI: 0-32) in the stretch group. There were no differences in any of the secondary outcomes. A simple progressive exercise protocol, performed every second day, resulted in superior self-reported outcome after 3 months compared with plantar-specific stretching. High-load strength training may aid in a quicker reduction in pain and improvements in function. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Motivational Interviewing provides the opportunity to health professionals to have an effective strategy to increase the level of readiness to change health behaviors. Along with the Transtheoretical Model (Stages of Change Model) compose the theoretical base of intervention in psychiatry settings. This study was aimed to change nutritious behavior of psychiatric patients using a specific Model of Change and Counseling implementing a health education program. A quasi-experimental design was adopted on a random sample of 60 psychiatric patients at Military Hospital of Athens. Patients were divided into two groups as follows; (a) Intervention Group (four sessions of counseling and encouraging motivation for modification of their nutritious habits), and (b) Control Group (simple information sessions about the principles of healthy alimentation). The mean age of Intervention Group (IG) was 43.9 ± 9.5 and Control Group (CG) 46.1 ± 9.1, ranging from 40 to 55 years old. Also, 26.7% of the participants were female, 23.3% were married and, 10% divorced. Our analyses showed that IG patients were significantly loss weight post-intervention compared to CG patients. Specifically, IG patients were significantly moderated the intake of starchy foods in every meal (p < 0.001) and the intake of fruits and vegetables (p < 0.001). Similarly, IG patients were moderated the intake of low fat dairy foods while they changed the full fat dairy foods with low fat (p < 0.001). Also important, IG patients showed significant enhance (80%) regarding drugs compliance, suggesting that 34% of the CG patients often forgot to take their medication. Finally, IG patients reported a positive attitude towards moderating unhealthy nutritious behaviors (p = 0.032). Our results confirms that health educational and promotional Interventions may change behavior of psychiatric patients and thus may positively influence their nutritious habits.

Usability of therapy controllers in elderly patients with deep brain stimulation

PubMed Central

2012-01-01

Background Technical devices are becoming more prevalent in society and also in medical care. Older adults need more support to learn new technologies than younger subjects. So far, no research has been done on the usability of patient controllers in deep brain stimulation in an elderly population. The aim of the study was to investigate the factors influencing the performance of elderly DBS patients with respect to usability aspects of Medtronic Access therapy controllers. Methods Time, mistakes and frequency of use of the controller were compared in 41 elderly DBS patients who prior to the study had already owned a therapy controller for more than six years. One group (n = 20, mean age = 66.4 years) was watching an instructional video and then completed practical assignments on a model implantable pulse generator (IPG). The other group (n = 21, mean age = 65.9 years) completed the tasks without having seen the video before. Any errors that patients made were documented and also corrected so that all of them received hands-on training. After six months all patients were re-evaluated on the dummy IPG in order to compare the effects of hands-on alone vs. video-based training combined with hands-on. Results The group that had seen the video before significantly outperformed the control group at both assessments with respect to number of errors. Both groups performed faster after six months compared to baseline and tend to use the controller more often than at baseline. Conclusion Our results indicate that elderly DBS patients who have been using the controller for several years still have various difficulties in operating the device. However, we also showed that age-specific training may improve the performance in older adults. In general, the design of DBS patient controllers should focus on the specific needs of the end-users. But as changes to medical devices take a long time to be implemented, video instructions with age-specific content plus hands-on training may improve learning for older adults. PMID:22330892

Background/Aims Duodenitis is not infrequent finding in patient undergoing endoscopy. However, hospitalized patients have a higher incidence of secondary duodenal mucosal lesions that might be related with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infection, tuberculosis, immunologic disorders, or other rare infections. We aimed to identify clinicopathologic features of duodenal mucosal lesions in hospitalized patients. Methods All hospitalized patients having duodenal mucosal lesions were identified by endoscopic registration data and pathologic data query from 2011 to 2014. The diagnostic index was designed to be sensitive; however, a detailed review of medical record and endoscopic findings was undertaken to improve specificity. Secondary duodenal lesion was defined as having specific reason to explain the duodenal lesion. Results Among 6,334 hospitalized patients have undergone upper endoscopy, endoscopic duodenal mucosal lesions was detected in 475 patients. Secondary duodenal lesions was 21 patients (4.4%) and the most frequent secondary cause was IBD (n = 7). The mean age of secondary group was significantly lower than that in primary group (42.3 ± 18.9 years vs. 58.5 ± 16.8 years, p = 0.00), and nonsteroidal anti-inflammatory drugs were less frequently used in secondary group, but there was no differences of gender or presence of Helicobacter pylori. The involvement of distal part of duodenum including postbulbitis or panduodenitis was more frequently detected in secondary group than in primary group. By multivariate regression analysis, younger age of 29 years and the disease extent were significant predictors for the secondary mucosal lesions. Conclusions Secondary duodenal mucosal lesions with different pathophysiology, such as IBD or CMV infection, are rare. Disease extent and age seems the most distinctive feature of secondary duodenal mucosal lesions. PMID:28823115

To analyse the presence of heightened sensory sensitivity in patients with anorexia nervosa, which seems similar but not identical to that described in patients with unexplained somatic symptoms or body dysmorphic disorder. We developed a sensory sensitivity scale in eating disorders (SASTCA), which measures the intensity of the response to specific somatosensory stimuli. The scale was completed by 48 patients with anorexia and a control group of 31 participants matched in age, sex and social and educational level. The results were compared with those obtained with the Barsky Somatosensory Amplification Scale (SSAS). The reliability (Cronbach's/alpha, 0.946; Guttman/ split-half, 0.936) and validity (ROC, 0.933) of the SASTCA scale are indicative of its high sensitivity and specificity. The anorexia group had a significantly higher mean score on the SASTCA scale than the control group (p<.001). Similarly, the patients with anorexia had a significantly higher mean value on the SSAS than the participants in the control group (p<.01), although the difference was less extreme. The 2 scales correlated positively (r=.634). These preliminary results suggest the presence in Anorexia of heightened sensory sensitivity which differs from the sensitivity of the control group. This sensitivity has a significant relationship with that described in patients with somatic complaints about health (SSD) or appearance (BDD). Could this heightened sensory sensitivity help us to explain the process of forming the distorted body self-concept (I'm fat, sick, ugly) in all these patients? Once its presence has been confirmed in other patients with anorexia, their relatives and other patients with somatic disorders this heightened sensitivity could constitute the somatic endophenotype of anorexia?

Patients who undergo major surgery for cancer are at high risk of postoperative sepsis. Early markers of septic complications would be useful for diagnosis and therapeutic management in patients with postoperative sepsis. The aim of this study was to investigate the association between early (first postoperative day) changes in interleukin 6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) serum concentrations and the occurrence of subsequent septic complications after major surgery. Serial blood samples were collected from 50 consecutive patients for determination of IL-6, PCT and CRP serum levels. Blood samples were obtained on the morning of surgery and on the morning of the first postoperative day. Sixteen patients developed septic complications during the first five postoperative days (group 1), and 34 patients developed no septic complications (group 2). On day 1, PCT and IL-6 levels were significantly higher in group 1 (P-values of 0.003 and 0.006, respectively) but CRP levels were similar. An IL-6 cut-off point set at 310 pg ml(-1) yielded a sensitivity of 90% and a specificity of 58% to differentiate group 1 patients from group 2 patients. When associated with the occurrence of SIRS on day 1 these values reached 100% and 79%, respectively. A PCT cut-off point set at 1.1 ng ml(-1) yielded a sensitivity of 81% and a specificity of 72%. When associated with the occurrence of SIRS on day 1, these values reached 100% and 86%, respectively. PCT and IL-6 appear to be early markers of subsequent postoperative sepsis in patients undergoing major surgery for cancer. These findings could allow identification of postoperative septic complications.

Objective: Candida esophagitis belongs to the most common AIDS-defining diseases; however, a comprehensive immune pathogenic concept is lacking. Design: We investigated the immune status of 37 HIV-1-infected patients from the Swiss HIV cohort study at diagnosis of Candida esophagitis, 1 year before, 1 year later and after 2 years of suppressed HIV RNA. We compared these patients with three groups: 37 HIV-1-infected patients without Candida esophagitis but similar CD4+ cell counts as the patients at diagnosis (advanced HIV group), 15 HIV-1-infected patients with CD4+ cell counts higher than 500 cells/μl, CD4+ cell nadirs higher than 350 cells/μl and suppressed HIV RNA under combination antiretroviral therapy (cART) (early cART group) and 20 healthy individuals. Methods: We investigated phenotype, cytokine production and proliferative capacity of different immune cells by flow cytometry and enzyme-linked immunosorbent spot. Results: We found that patients with Candida esophagitis had nearly abolished CD4+ cell proliferation in response to Candida albicans, significantly increased percentages of dysfunctional CD4+ cells, significantly decreased cytotoxic natural killer cell counts and peripheral innate lymphoid cell counts and significantly reduced IFN-γ and IL-17 production compared with the early cART group and healthy individuals. Most of these defects remained for more than 2 years despite viral suppression. The advanced HIV group without opportunistic infection showed partly improved immune recovery. Conclusion: Our data indicate that Candida esophagitis in HIV-1-infected patients is caused by an accumulation of multiple, partly Candida-specific immunological defects. Long-term immune recovery is impaired, illustrating that specific immunological gaps persist despite cART. These data also support the rationale for early cART initiation to prevent irreversible immune defects. PMID:27149086

Use of ICP monitoring is considered to be part of "standard of care" in management of severe traumatic brain injury, but it is rarely used in developing countries. The authors present a study which evaluates the efficacy and outcomes of ICP monitoring at a high-volume trauma center in India. Data on management and outcomes for 126 patients who were admitted with diffuse traumatic brain injury (GCS 3-8) were studied prospectively over an 18-month period. These patients were treated by one of the two specific protocols: ICP monitoring-based or non-ICP monitoring-based. The primary outcome was measured based on 2 weeks mortality and GOS-E at 1, 3, and 6 months. Secondary outcome was measured based on need for brain-specific treatment, length of ICU stay, and radiation exposure. Mortality in a subset of patients who underwent surgical intervention later due to increased ICP values, drop in GCS, or radiological deterioration was noted to be significantly lower in the ICP monitoring group (p = 0.03), in spite of statistically insignificant difference in overall mortality rates between groups. GOS-E scores at 1 month were significantly better (p = 0.033) in ICP monitoring group, even though they equalized at 3 and 6 months. The need for brain-specific treatment (p < 0.001), radiation exposure (p < 0.001), and length of ICU stay (p = 0.013) was significantly lower in the ICP monitoring group. ICP monitoring-based treatment protocol helps in achieving faster recovery; lowers mortality rates in operated patients; and reduces ICU stay, radiation exposure, and the need for brain-specific treatment.

The efforts to improve health care delivery usually involve studies and analysis of patient populations and healthcare systems. In this dissertation, I present the research conducted in the following areas: identifying patient groups, improving treatments for specific conditions by using statistical as well as data mining techniques, and developing new operation research models to increase system efficiency from the health institutes' perspective. The results provide better understanding of high risk patient groups, more accuracy in detecting disease' correlations and practical scheduling tools that consider uncertain operation durations and real-life constraints.

Obsessive compulsive disorder (OCD) is a clinically heterogeneous disorder; OCD with poor insight has been suggested to be a specific clinical subtype. Neurological soft signs (NSSs) may be helpful to identify the specific subtypes of OCD patients. In the present study, we aimed to compare OCD patients with poor insight with OCD patients having good insight, and healthy individuals. Sixty-four OCD patients (38 with good insight and 26 with poor insight), and 32 healthy subjects were enrolled in the present study. The Overvalued Ideas Scale (OVIS) was used to determine OCD patients with poor insight. NSSs were assessed by using the Neurological Evaluation Scale (NES). Two OCD groups had significantly higher total NES scores compared to controls (p=.000). Compared to healthy controls, OCD patients with poor insight performed significantly worse on all NES subscales, and they had significantly more NSSs on motor coordination, and sensory integration subscales compared to the OCD with good insight group. Our results suggested that OCD patients with poor insight exhibit more extensive neurodevelopmental impairments compared to OCD patients with good insight. Copyright © 2011 Elsevier Inc.

To retrospectively determine the sensitivity and specificity of magnetic resonance (MR) imaging findings in patients with clinical athletic pubalgia, with either surgical or physical examination findings as the reference standard. Institutional review board approval was granted for this HIPAA-compliant study, and informed consent was waived. MR imaging studies in 141 patients (134 male patients, seven female patients; mean age, 30.1 years; range, 17-71 years) who had been referred to a subspecialist because of groin pain were reviewed for findings including hernia, pubic bone marrow edema, secondary cleft sign, and rectus abdominis and adductor tendon injury. MR imaging findings were compared with surgical findings for 102 patients, physical examination findings for all 141 patients, and MR imaging findings in an asymptomatic control group of 25 men (mean age, 29.8 years; range, 18-39 years). Sensitivity and specificity of MR imaging for rectus abdominis and adductor tendon injury were determined by using a chi(2) analysis, and significance of the findings was analyzed with an unpaired Student t test. Disease patterns seen at MR imaging were compared with those reported in the surgical and sports medicine literature. One hundred thirty-eight (98%) of 141 patients had findings at MR imaging that could cause groin pain. Compared with surgery, MR imaging had a sensitivity and specificity, respectively, of 68% and 100% for rectus abdominis tendon injury and 86% and 89% for adductor tendon injury. Injury in each of these structures was significantly more common in the patient group than in the control group (P < .001). Only two patients had hernias at surgery. At MR imaging, injury or disease could be fit into distinct groups, including osteitis pubis, adductor compartment injury, rectus abdominis tendon injury, and injury or disease remote from the pubic symphysis. Patients with injury involving the rectus abdominis insertion were most likely to go on to surgical pelvic floor repair. MR imaging depicts patterns of findings in patients with athletic pubalgia, including rectus abdominis insertional injury, thigh adductor injury, and articular diseases at the pubic symphysis (osteitis pubis).

Neuropsychological group study methodology is considered one of the primary methods to further understanding of the organisation of frontal ‘executive’ functions. Typically, patients with frontal lesions caused by stroke or tumours have been grouped together to obtain sufficient power. However, it has been debated whether it is methodologically appropriate to group together patients with neurological lesions of different aetiologies. Despite this debate, very few studies have directly compared the performance of patients with different neurological aetiologies on neuropsychological measures. The few that did included patients with both anterior and posterior lesions. We present the first comprehensive retrospective comparison of the impact of lesions of different aetiologies on neuropsychological performance in a large number of patients whose lesion solely affects the frontal cortex. We investigated patients who had a cerebrovascular accident (CVA), high (HGT) or low grade (LGT) tumour, or meningioma, all at the post-operative stage. The same frontal ‘executive’ (Raven's Advanced Progressive Matrices, Stroop Colour-Word Test, Letter Fluency-S; Trail Making Test Part B) and nominal (Graded Naming Test) tasks were compared. Patients' performance was compared across aetiologies controlling for age and NART IQ scores. Assessments of focal frontal lesion location, lesion volume, global brain atrophy and non-specific white matter (WM) changes were undertaken and compared across the four aetiology. We found no significant difference in performance between the four aetiology subgroups on the ‘frontal’ executive and nominal tasks. However, we found strong effects of premorbid IQ on all cognitive tasks and robust effects of age only on the frontal tasks. We also compared specific aetiology subgroups directly, as previously reported in the literature. Overall we found no significant differences in the performance of CVA and tumour patients, or LGT and HGT patients or LGT, HGT and meningioma's on our four frontal tests. No difference was found with respect to the location of frontal lesions, lesion volume, global brain atrophy and non-specific WM changes between the subgroups. Our results suggest that the grouping of frontal patients caused by different aetiologies is a pragmatic, justified methodological approach that can help to further understanding of the organisation of frontal executive functions.

To improve on the existing risk-stratification systems for prostate cancer. This was a retrospective investigation including 2 248 patients undergoing dose-escalated external beam radiotherapy (EBRT) at a single institution. We separated National Comprehensive Cancer Network (NCCN) intermediate-risk prostate cancer into 'favourable' and 'unfavourable' groups based on primary Gleason pattern, percentage of positive biopsy cores (PPBC), and number of NCCN intermediate-risk factors. Similarly, NCCN high-risk prostate cancer was stratified into 'standard' and 'very high-risk' groups based on primary Gleason pattern, PPBC, number of NCCN high-risk factors, and stage T3b-T4 disease. Patients with unfavourable-intermediate-risk (UIR) prostate cancer had significantly inferior prostate-specific antigen relapse-free survival (PSA-RFS, P < 0.001), distant metastasis-free survival (DMFS, P < 0.001), prostate cancer-specific mortality (PCSM, P < 0.001), and overall survival (OS, P < 0.001) compared with patients with favourable-intermediate-risk (FIR) prostate cancer. Similarly, patients with very high-risk (VHR) prostate cancer had significantly worse PSA-RFS (P < 0.001), DMFS (P < 0.001), and PCSM (P = 0.001) compared with patients with standard high-risk (SHR) prostate cancer. Moreover, patients with FIR and low-risk prostate cancer had similar outcomes, as did patients with UIR and SHR prostate cancer. Consequently, we propose the following risk-stratification system: Group 1, low risk and FIR; Group 2, UIR and SHR; and Group 3, VHR. These groups have markedly different outcomes, with 8-year distant metastasis rates of 3%, 9%, and 29% (P < 0.001) for Groups 1, 2, and 3, respectively, and 8-year PCSM of 1%, 4%, and 13% (P < 0.001) after EBRT. This modified stratification system was significantly more accurate than the three-tiered NCCN system currently in clinical use for all outcomes. Modifying the NCCN risk-stratification system to group FIR with low-risk patients and UIR with SHR patients, results in modestly improved prediction of outcomes, potentially allowing better personalisation of therapeutic recommendations. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

The aim of the present study was to assess energy and nutrient intake in a group of women with restrictive AN (r-AN) compared with a control group. Thirteen r-AN patients and 13 healthy female controls completed 7-d food records. Intake of macro- and micronutrients was compared between the two groups as well as to the Dietary Reference Intake for the Italian Population (LARN) for specific ages. Additionally, the r-AN patients underwent indirect calorimetry for measuring resting energy expenditure (REE). Total energy intake was significantly lower in the r-AN group than in controls (906 ± 224 vs 1660 ± 139, respectively; P < 0.01). Nutrient composition significantly differed, as well. Mean intake of sodium, phosphorus, and zinc was higher in controls than in the women with r-AN (P < 0.01), but neither group of women met LARN recommendations for potassium, calcium, or iron intake. With respect to vitamins, no significant differences were found for riboflavin or vitamins A, B 12 , or C between groups, whereas levels of other vitamins differed (P < 0.01). Both groups failed to meet the LARN recommendation for vitamin D intake; moreover, none of the r-AN patients met recommended intake levels of vitamin E, thiamine, niacin, and folate. Intakes reported by r-AN patients did not meet requirements for most micronutrients evaluated in this study and, as expected, both energy needs and specific dietary patterns differed between groups. Therefore, a careful evaluation of food consumption should be recommended to reduce nutritional gaps in these patients. According to these preliminary observations, nutritional counseling, mainly focused on calcium and vitamin D intake, should be suggested for healthy women, as well. Copyright © 2017 Elsevier Inc.

Prior studies have reported that the presence of prior biliary stent may interfere with EUS visualization of pancreatic tumors. We aimed to compare the influence of the biliary plastic and fully covered self-expanding metal stents (CSEMS) on the accuracy of EUS-FNA cytology in patients with solid pancreatic masses. We conducted a retrospective study evaluating 677 patients with solid pancreatic head/uncinate lesions and a previous biliary stent in whom EUS-FNA was performed. The patients were stratified into two groups: (1) those with a plastic stents and (2) those with CSEMS. Performance characteristics of EUS-FNA including the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were compared between the two groups. The frequency of obtaining an adequate cytology by EUS-FNA was similar in both the CSEMS group and the plastic stent group (97 vs. 97.1 % respectively; p = 1.0). The sensitivity, specificity, and accuracy of EUS-FNA was not significantly different between patients with CSEMS and plastic stents (96.8, 100, 100 % and 97.3, 98, 99.8 %, respectively). The negative predictive value for EUS-FNA was lower in the CSEMS group compared to the plastic stent group (66.6 vs. 78.1 % respectively; p = 0.42). There was one false-positive cytology in the plastic stent group compared to none in the CSEMS group. In a retrospective cohort trial, EUS-FNA was found to be highly accurate and safe in diagnosing patients with suspected pancreatic cancer, even in the presence of a plastic or metallic biliary stent. The presence of a stent did not contribute to a higher false-positive cytology rate.

The aim of this study was to explore the effect of electroacupuncture (EA) on immune function in patients undergoing supratentorial craniotomy. We also examined whether point specificity in EA was present. The study involved 29 patients undergoing craniotomy. The patients were divided into three groups: a control (C, n=10), an EA (A, n=9) and a sham acupoints group (S, n=10). Blood samples were collected at the following time points: before anesthesia (T0), 4 h after the induction of anesthesia (T1), 1 day post-surgery (T2) and 2 days post-surgery (T3) to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10), immunoglobulin M (IgM), IgA and IgG. Data were analyzed using SPSS 13.0 software. When comparing the levels of cytokines following surgery, we observed that the peripheral blood IL-8 levels in groups A and S were increased significantly compared with those of group C at 1 and 2 days after surgery. When comparing immunoglobulin levels after surgery, we established that the peripheral blood IgA levels in group C had decreased significantly compared to those of group A and group S 4 h after induction of anesthesia and 1 day after surgery. However, there was no significant difference between group A and group S. Compared with simple general anesthesia, acupuncture combined with anesthesia partially reduces immune suppression in the perioperative periods under the same conditions as the simple general anesthesia. Point specificity in EA was not present. PMID:24137250

Intensive group training using principles of graded activity has been proven to be effective in occupational care for workers with chronic low back pain. Objective of the study was to compare the effects of an intensive group training protocol aimed at returning to normal daily activities and guideline physiotherapy for primary care patients with non-specific chronic low back pain. The study was designed as pragmatic randomised controlled trial with a setup of 105 primary care physiotherapists in 49 practices and 114 patients with non-specific low back pain of more than 12 weeks duration participated in the study. In the intensive group training protocol exercise therapy, back school and operant-conditioning behavioural principles are combined. Patients were treated during 10 individual sessions along 20 group sessions. Usual care consisted of physiotherapy according to the Dutch guidelines for Low Back Pain. Main outcome measures were functional disability (Roland Morris disability questionnaire), pain intensity, perceived recovery and sick leave because of low back pain assessed at baseline and after 6, 13, 26 and 52 weeks. Both an intention-to-treat analysis and a per-protocol analysis were performed. Multilevel analysis did not show significant differences between both treatment groups on any outcome measures during the complete follow-up period, with one exception. After 26 weeks the protocol group showed more reduction in pain intensity than the guideline group, but this difference was absent after 52 weeks. We finally conclude that an intensive group training protocol was not more effective than usual physiotherapy for chronic low back pain.

development of cytomegalovirus (CMV)-specific CD8+ T cell response is crucial in preventing symptomatic CMV infection specially, in stem cell transplant (SCT) patients. The aim of this study was to evaluate CMV-specific CD8+ T cell reconstitution in allogeneic SCT recipients and to study the possible association between CMV-specific CD8+ T cell recovery with protection from CMV reactivation and persistency. Human leuKocyte antigen (HLA)-tetramers were used for CMV-specific CD8+ cell quantitation by Flow cytometry in twenty post-allogeneic SCT patients. Nine patients (45%) developed rapid recovery of CMV-specific CD8+ cells, among them; 7 patients (78%) had no CMV reactivation in the first 95 days post-transplant. Five patients had developed persistent CMV viremia; all of them had not developed CMV-specific CD8+ recovery till day 95 post-transplant. Patients with persistent CMV viremia had a statistically significant lower means of CMV-specific CD8+ percent and absolute count compared to those without persistent viremia (p = .001, .015), respectively. The incidence of CMV reactivation and persistency was higher among patients with delayed CMV-specific CD8+ reconstitution in the first 95 days post-transplant. CMV-specific CD8+ cells can help in categorizing patients into risk groups: (early recovery/low risk) and (delayed recovery/increased risk), this tool may guide clinicians in the selection of patients who may profit from prophylactic antiviral therapy and frequent viral monitoring.

To evaluate the effects of a nurse-led, hospital-based heart failure specific education session with a three-month telephone follow-up on self-care behaviour, care dependency and quality of life for patients with chronic heart failure. Patient education in patients with heart failure is able to promote heart failure-specific self-care, to reduce mortality, morbidity and rehospitalisation rates and to enhance quality of life, especially if heart failure education is embedded in a multidisciplinary approach. Evidence of the effect of a nurse-led self-care education, quality of life and care dependency in addition to standard medical treatment in Germany is lacking. Nonblinded, prospective, single-centre, randomised controlled trial. Sixty-four patients were allocated either to the intervention group or to the control group. Patients in the intervention group received education about heart failure self-care with a consecutive telephone follow-up over three months in addition to standard medical treatment. Patients in the control group received standard medical treatment only. Data of 110 patients (58 in the intervention group and 52 in the control group) with a mean age of 62 years and mean left ventricular ejection fraction of 28·2% could be analysed. Self-care education had a significant influence on overall heart failure self-care but not on quality of life and care dependency. A single education session with a consecutive telephone follow-up is able to improve overall self-care behaviours but not quality of life. Care dependency was not influenced by the education session. The easy to implement and short educational intervention has a positive effect on self-care behaviour for patients with heart failure. However, there was no effect on quality of life and care dependency. To improve quality of life and to influence care dependency, different measures have to be applied. © 2015 John Wiley & Sons Ltd.

Background Leptospirosis is an important zoonotic disease worldwide. Humans usually present a mild non-specific febrile illness, but a proportion of them develop more severe outcomes, such as multi-organ failure, lung hemorrhage and death. Such complications are thought to depend on several factors, including the host immunity. Protective immunity is associated with humoral immune response, but little is known about the immune response mounted during naturally-acquired Leptospira infection. Methods and principal findings Here, we used protein microarray chip to profile the antibody responses of patients with severe and mild leptospirosis against the complete Leptospira interrogans serovar Copenhageni predicted ORFeome. We discovered a limited number of immunodominant antigens, with 36 antigens specific to patients, of which 11 were potential serodiagnostic antigens, identified at acute phase, and 33 were potential subunit vaccine targets, detected after recovery. Moreover, we found distinct antibody profiles in patients with different clinical outcomes: in the severe group, overall IgM responses do not change and IgG responses increase over time, while both IgM and IgG responses remain stable in the mild patient group. Analyses of individual patients’ responses showed that >74% of patients in the severe group had significant IgG increases over time compared to 29% of patients in the mild group. Additionally, 90% of IgM responses did not change over time in the mild group, compared to ~51% in the severe group. Conclusions In the present study, we detected antibody profiles associated with disease severity and speculate that patients with mild disease were protected from severe outcomes due to pre-existing antibodies, while patients with severe leptospirosis demonstrated an antibody profile typical of first exposure. Our findings represent a significant advance in the understanding of the humoral immune response to Leptospira infection, and we have identified new targets for the development of subunit vaccines and diagnostic tests.

Several studies on avoidance of house-dust-mite (HDM) and cat allergens have been carried out, most of them in asthmatic patients and only a few in patients with atopic dermatitis (AD). No study so far has focused on which subgroup of AD patients benefits from avoidance measures. Forty adult patients with AD completed the 12-month avoidance study. They were divided into an active treatment (n = 22) and a placebo (n = 18) group. Active treatment comprised use of polyurethane-coated cotton encasings for bedding, and placebo use of cotton covers. Patients came for regular checkups during the 12-month period, when eczema severity was assessed and blood samples were analyzed for total IgE, HDM- and cat-specific IgE and soluble CD30 (sCD30) in serum. Dust samples were collected from mattresses before treatment and after 3, 6, and 12 months, and analyzed for content of HDM and cat allergen. Eczema severity decreased significantly in both groups (P < 0.001), with a more pronounced decrease in patients with active covers. The HDM exposure decreased significantly in the active treatment group (P < 0.001), and the levels of HDM-specific IgE were reduced (P<0.05). Exposure to cat allergens was unchanged in the active treatment group but decreased, albeit not significantly (P=0.19), in the placebo group. sCD30 levels were significantly reduced in both groups (P<0.001). Patients not sensitized to HDM allergens benefited from the bedcovers as much as sensitized patients. Occlusive bedding significantly reduced HDM exposure in bed (P<0.001) and eczema severity, and sCD30 levels decreased significantly (P<0.001). Patients not sensitized to HDM and not exposed to HDM allergens benefited equally from use of the bedcovers, a result which could be due to a reduction of other important allergens, superantigens, or irritants in bed. We therefore recommend the use of bedcovers as part of treatment for AD.

To assess the effect of aerobic walking training as compared to active training, which includes muscle strengthening, on functional abilities among patients with chronic low back pain. Randomized controlled clinical trial with blind assessors. Outpatient clinic. Fifty-two sedentary patients, aged 18-65 years with chronic low back pain. Patients who were post surgery, post trauma, with cardiovascular problems, and with oncological disease were excluded. Experimental 'walking' group: moderate intense treadmill walking; control 'exercise' group: specific low back exercise; both, twice a week for six weeks. Six-minute walking test, Fear-Avoidance Belief Questionnaire, back and abdomen muscle endurance tests, Oswestry Disability Questionnaire, Low Back Pain Functional Scale (LBPFS). Significant improvements were noted in all outcome measures in both groups with non-significant difference between groups. The mean distance in metres covered during 6 minutes increased by 70.7 (95% confidence interval (CI) 12.3-127.7) in the 'walking' group and by 43.8 (95% CI 19.6-68.0) in the 'exercise' group. The trunk flexor endurance test showed significant improvement in both groups, increasing by 0.6 (95% CI 0.0-1.1) in the 'walking' group and by 1.1 (95% CI 0.3-1.8) in the 'exercise' group. A six-week walk training programme was as effective as six weeks of specific strengthening exercises programme for the low back.

Dizziness and unsteadiness are common symptoms following a whiplash injury. To compare the effect of 3 exercise programs on balance, dizziness, proprioception and pain in patients with chronic whiplash complaining of dizziness. A sub-analysis of a randomized study. One hundred and forty subjects were randomized to either a physiotherapist-guided neck-specific exercise (NSE), physiotherapist-guided neck-specific exercise, with a behavioural approach (NSEB) or prescription of general physical activity (PPA) group. Pre intervention, 3, 6 and 12 months post baseline they completed the University of California Los Angeles Dizziness Questionnaire (UCLA-DQ), Visual Analogue Scales (VAS) for, dizziness at rest and during activity and physical measures (static and dynamic clinical balance tests and head repositioning accuracy (HRA)). There were significant time by group differences with respect to dizziness during activity and UCLA-Q favouring the physiotherapy led neck specific exercise group with a behavioural approach. Within group analysis of changes over time also revealed significant changes in most variables apart from static balance. Between and within group comparisons suggest that physiotherapist led neck exercise groups including a behavioural approach had advantages in improving measures of dizziness compared with the general physical activity group, although many still complained of dizziness and balance impairment. Future studies should consider exercises specifically designed to address balance, dizziness and cervical proprioception in those with persistent whiplash. Crown Copyright © 2015.

A Dutch online patient decision aid to support prosthetic heart valve selection was recently developed. A multicenter randomized controlled trial was conducted to assess whether use of the patient decision aid results in optimization of shared decision making in prosthetic heart valve selection. In a 5-center randomized controlled trial, patients were allocated to receive either standard preoperative care (control group) or additional access to the patient decision aid (intervention group). Legally capable adult patients accepted for elective isolated or combined aortic and mitral valve replacement were included. Primary outcome was preoperative decisional conflict (Decisional Conflict Scale); secondary outcomes included patient knowledge, involvement in valve selection, anxiety and depression, (valve-specific) quality of life, and regret. Out of 306 eligible patients, 155 were randomized (78 control and 77 intervention). Preoperative decisional conflict did not differ between the groups (34% versus 33%; P =0.834). Intervention patients felt better informed (median Decisional Conflict Scale informed subscore: 8 versus 17; P =0.046) and had a better knowledge of prosthetic valves (85% versus 68%; P =0.004). Intervention patients experienced less anxiety and depression (median Hospital Anxiety and Depression Scale score: 6 versus 9; P =0.015) and better mental well-being (mean Short Form Health Survey score: 54 versus 50; P =0.032). Three months postoperatively, valve-specific quality of life and regret did not differ between the groups. A patient decision aid to support shared decision making in prosthetic heart valve selection does not lower decisional conflict. It does result in more knowledgeable, better informed, and less anxious and depressed patients, with a better mental well-being. http://www.trialregister.nl.

To describe the prevalence of nonacute conditions among patients seeking health care in a defined US population, emphasizing age, sex, and ethnic differences. The Rochester Epidemiology Project (REP) medical records linkage system was used to identify all residents of Olmsted County, Minnesota, on April 1, 2009, who had consented to review of their medical records for research (142,377 patients). We then electronically extracted all International Classification of Diseases, Ninth Revision codes noted in the records of these patients by any health care institution between January 1, 2005, and December 31, 2009. We grouped International Classification of Diseases, Ninth Revision codes into clinical classification codes and then into 47 broader disease groups associated with health-related quality of life. Age- and sex-specific prevalence was estimated by dividing the number of individuals within each group by the corresponding age- and sex-specific population. Patients within a group who had multiple codes were counted only once. We included a total of 142,377 patients, 75,512 (53%) of whom were female. Skin disorders (42.7%), osteoarthritis and joint disorders (33.6%), back problems (23.9%), disorders of lipid metabolism (22.4%), and upper respiratory tract disease (22.1%, excluding asthma) were the most prevalent disease groups in this population. Ten of the 15 most prevalent disease groups were more common in women in almost all age groups, whereas disorders of lipid metabolism, hypertension, and diabetes were more common in men. Additionally, the prevalence of 7 of the 10 most common groups increased with advancing age. Prevalence also varied across ethnic groups (whites, blacks, and Asians). Our findings suggest areas for focused research that may lead to better health care delivery and improved population health. Copyright © 2013 Mayo Foundation for Medical Education and Research.

Robot-assisted minimally invasive surgical systems enable procedures with reduced pain, recovery time, and scarring compared to traditional surgery. While these improvements benefit a large number of patients, safe access to diseased sites is not always possible for specialized patient groups, including pediatric patients, due to their anatomical differences. We propose a patient-specific design paradigm that leverages the surgeon's expertise to design and fabricate robots based on preoperative medical images. The components of the patient-specific robot design process are a virtual reality design interface enabling the surgeon to design patient-specific tools, 3-D printing of these tools with a biodegradable polyester, and an actuation and control system for deployment. The designed robot is a concentric tube robot, a type of continuum robot constructed from precurved, elastic, nesting tubes. We demonstrate the overall patient-specific design workflow, from preoperative images to physical implementation, for an example clinical scenario: nonlinear renal access to a pediatric kidney. We also measure the system's behavior as it is deployed through real and artificial tissue. System integration and successful benchtop experiments in ex vivo liver and in a phantom patient model demonstrate the feasibility of using a patient-specific design workflow to plan, fabricate, and deploy personalized, flexible continuum robots.

Despite extensive research on individual diseases, population-based knowledge about reasons for acute medical admissions remains limited. Our aim was to examine primary diagnoses, Charlson Comorbidity Index (CCI) score, age, and gender among patients admitted acutely to medical departments in Denmark. In this population-based observational study, 264,265 acute medical patients admitted during 2010 were identified in the Danish National Registry of Patients (DNRP), covering all hospitals in Denmark. Reasons for acute admissions were assessed by primary diagnoses, grouped according to the International Classification of Diseases 10th edition. Additionally, the CCI score, age and gender were presented according to each diagnostic group. Two-thirds of the patients had one of the four following reasons for admission: cardiovascular diseases (19.3%), non-specific Z-diagnoses ("Factors influencing health status and contact with health services") (16.9%), infectious diseases (15.5%), and non-specific R-diagnoses ("Symptoms and abnormal findings, not elsewhere classified") (11.8%). In total, 45% of the patients had a CCI score of one or more and there was a considerable overlap between the patients' chronic diseases and the reason for admission. The median age of the study population was 64 years (IQR 47-77 years), ranging from 46 years (IQR 27-66) for injury and poisoning to 74 years (IQR 60-83) for hematological diseases. Gender representation varied considerably within the diagnostic groups, for example with male predominance in mental disorders (59.0%) and female predominance in diseases of the musculoskeletal system (57.8%). Our study identifies that acute medical patients often present with non-specific symptoms or complications related to their chronic diseases.

Patient navigation is increasingly being directed at adolescent and young adult (AYA) patients. This study provides a novel description of differences in AYA cancer patients' preferences for navigation services by developmental age at diagnosis. Eligible patients were diagnosed with cancer between ages 15 and 39 and had completed at least 1 month of treatment. Between October 2015 and January 2016, patients completed semi-structured interviews about navigation preferences. Summary statistics of demographic and cancer characteristics were generated. Differences in patient navigation preferences were examined through qualitative analyses by developmental age at diagnosis. AYAs were interviewed (adolescents 15-18 years N = 8; emerging adults 19-25 years N = 8; young adults 26-39 years N = 23). On average, participants were 4.5 years from diagnosis. All age groups were interested in face-to-face connection with a navigator and using multiple communication platforms (phone, text, email) to follow-up. Three of the most frequently cited needs were insurance, finances, and information. AYAs differed in support, healthcare, and resource preferences by developmental age; only adolescents preferred educational support. While all groups preferred financial and family support, the specific type of assistance (medical versus living expenses, partner/spouse, child, or parental assistance) varied by age group. AYAs with cancer have different preferences for patient navigation by developmental age at diagnosis. AYAs are not a one-size-fits-all population, and navigation programs can better assist AYAs when services are targeted to appropriate developmental ages. Future research should examine fertility and navigation preferences by time since diagnosis. While some navigation needs to span the AYA age range, other needs are specific to developmental age.

Impaired facial affect recognition (FAR) is observed in schizophrenia and autism spectrum disorder (ASD) and has been linked to amygdala and fusiform gyrus dysfunction. ASD patient's impairments seem to be more pronounced during implicit rather than explicit FAR, whereas for schizophrenia data are inconsistent. However, there are no studies comparing both patient groups in an identical design. The aim of this three-group study was to identify (i) whether FAR alterations are equally present in both groups, (ii) whether they are present rather during implicit or explicit FAR, (iii) and whether they are conveyed by similar or disorder-specific neural mechanisms. Using fMRI, we investigated neural activation during explicit and implicit negative and neutral FAR in 33 young-adult individuals with ASD, 20 subjects with paranoid-schizophrenia and 25 IQ- and gender-matched controls individuals. Differences in activation patterns between each clinical group and controls, respectively were found exclusively for implicit FAR in amygdala and fusiform gyrus. In addition, the ASD group additionally showed reduced activations in medial prefrontal cortex (PFC), bilateral dorso-lateral PFC, ventro-lateral PFC, posterior-superior temporal sulcus and left temporo-parietal junction. Although subjects with ASD showed more widespread altered activation patterns, a direct comparison between both patient groups did not show disorder-specific deficits in neither patient group. In summary, our findings are consistent with a common neural deficit during implicit negative facial affect recognition in schizophrenia and autism spectrum disorders.

A High Frequency of HIV-Specific Circulating Follicular Helper T Cells Is Associated with Preserved Memory B Cell Responses in HIV Controllers.

Follicular helper T cells (Tfh) play an essential role in the affinity maturation of the antibody response by providing help to B cells. To determine whether this CD4 + T cell subset may contribute to the spontaneous control of HIV infection, we analyzed the phenotype and function of circulating Tfh (cTfh) in patients from the ANRS CO21 CODEX cohort who naturally controlled HIV-1 replication to undetectable levels and compared them to treated patients with similarly low viral loads. HIV-specific cTfh (Tet + ), detected by Gag-major histocompatibility complex class II (MHC-II) tetramer labeling in the CD45RA - CXCR5 + CD4 + T cell population, proved more frequent in the controller group ( P = 0.002). The frequency of PD-1 expression in Tet + cTfh was increased in both groups (median, >75%) compared to total cTfh (<30%), but the intensity of PD-1 expression per cell remained higher in the treated patient group ( P = 0.02), pointing to the persistence of abnormal immune activation in treated patients. The function of cTfh, analyzed by the capacity to promote IgG secretion in cocultures with autologous memory B cells, did not show major differences between groups in terms of total IgG production but proved significantly more efficient in the controller group when measuring HIV-specific IgG production. The frequency of Tet + cTfh correlated with HIV-specific IgG production ( R = 0.71 for Gag-specific and R = 0.79 for Env-specific IgG, respectively). Taken together, our findings indicate that key cTfh-B cell interactions are preserved in controlled HIV infection, resulting in potent memory B cell responses that may play an underappreciated role in HIV control. IMPORTANCE The rare patients who spontaneously control HIV replication in the absence of therapy provide a unique model to identify determinants of an effective anti-HIV immune response. HIV controllers show signs of particularly efficient antiviral T cell responses, while their humoral response was until recently considered to play only a minor role in viral control. However, emerging evidence suggests that HIV controllers maintain a significant but "silent" antiviral memory B cell population that can be reactivated upon antigenic stimulation. We report that cTfh help likely contributes to the persistence of controller memory B cell responses, as the frequency of HIV-specific cTfh correlated with the induction of HIV-specific antibodies in functional assays. These findings suggest that T follicular help may contribute to HIV control and highlight the need for inducing such help in HIV vaccine strategies that aim at eliciting persistent B cell responses.

We have validated our touch-screen-modified FRAX® tool against the traditional healthcare professional-led questionnaire, demonstrating strong concordance between doctor- and patient-derived results. We will use this in outpatient clinics and general practice to increase our capture rate of at-risk patients, making valuable use of otherwise wasted patient waiting times. Outpatient clinics offer an opportunity to collect valuable health information from a captive population. We have previously developed a modified fracture risk assessment (FRAX®) tool, enabling patients to self-assess their osteoporotic fracture risk in a touch-screen computer format and demonstrated its acceptability with patients. We aim to validate the accuracy of our tool against the traditional questionnaire. Fifty patients over 50 years of age within the fracture clinic independently completed a paper equivalent of our touch-screen-modified FRAX® questionnaire. Responses were analysed against the traditional healthcare professional (HCP)-led questionnaire which was carried out afterwards. Correlation was assessed by sensitivity, specificity, Cohen's kappa statistic and Fisher's exact test for each potential FRAX® outcome of "treat", "measure BMD" and "lifestyle advice". Age range was 51-98 years. The FRAX® tool was completed by 88 % of patients; six patients lacked confidence in estimating either their height or weight. Following question adjustment according to patient response and feedback, our tool achieved >95 % sensitivity and specificity for the "treat" and "lifestyle advice" groups, and 79 % sensitivity and 100 % specificity in the "measure BMD" group. Cohen's kappa value ranged from 0.823 to 0.995 across all groups, demonstrating "very good" agreement for all. Fisher's exact test demonstrated significant concordance between doctor and patient decisions. Our modified tool provides a simple, accurate and reliable method for patients to self-report their own FRAX® score outside the clinical contact period, thus releasing the HCP from the time required to complete the questionnaire and potentially increasing our capture rate of at-risk patients.

Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical planning, combined with patient-specific surgical guides, has the potential to improve pre-operative understanding of patient anatomy as well as intra-operative accuracy. For patients with malunion of the distal radius fracture, this technology could significantly improve clinical outcomes that largely depend on the quality of restoration of normal anatomy. Therefore, the objective of this study is to compare patient outcomes after corrective osteotomy for distal radius malunion with and without preoperative computer-assisted planning and peri-operative patient-specific surgical guides. This study is a multi-center randomized controlled trial of conventional planning versus computer-assisted planning for surgical correction of distal radius malunion. Adult patients with extra-articular malunion of the distal radius will be invited to enroll in our study. After providing informed consent, subjects will be randomized to two groups: one group will receive corrective surgery with conventional preoperative planning, while the other will receive corrective surgery with computer-assisted pre-operative planning and peri-operative patient specific surgical guides. In the computer-assisted planning group, a CT scan of the affected forearm as well as the normal, contralateral forearm will be obtained. The images will be used to construct a 3D anatomical model of the defect and patient-specific surgical guides will be manufactured. Outcome will be measured by DASH and PRWE scores, grip strength, radiographic measurements, and patient satisfaction at 3, 6, and 12 months postoperatively. Computer-assisted surgical planning, combined with patient-specific surgical guides, is a powerful new technology that has the potential to improve the accuracy and consistency of orthopaedic surgery. To date, the role of this technology in upper extremity surgery has not been adequately investigated, and it is unclear whether its use provides any significant clinical benefit over traditional preoperative imaging protocols. Our study will represent the first randomized controlled trial investigating the use of computer assisted surgery in corrective osteotomy for distal radius malunions. NCT01193010.

Myositis-specific autoantibodies: an important tool to support diagnosis of myositis.

PubMed

Betteridge, Z; McHugh, N

2016-07-01

The idiopathic inflammatory myopathies are characterized by muscle weakness, skin disease and internal organ involvement. Autoimmunity is known to have a role in myositis pathogenesis, and myositis-specific autoantibodies, targeting important intracellular proteins, are regarded as key biomarkers aiding in the diagnosis of patients. In recent years, a number of novel myositis autoantibodies including anti-TIF1, anti-NXP2, anti-MDA5, anti-SAE, anti-HMGCR and anti-cN1A have been identified in both adult and juvenile patients. These autoantibodies correlate with distinct clinical manifestations and importantly are found in inclusion body, statin-induced, clinically amyopathic and juvenile groups of myositis patients, previously believed to be mainly autoantibody negative. In this review, we will describe the main myositis-specific and myositis-associated autoantibodies and their frequencies and clinical associations across different ages and ethnic groups. We will also discuss preliminary studies investigating correlations between specific myositis autoantibody titres and clinical markers of disease course, collectively demonstrating the utility of myositis autoantibodies as both diagnostic and prognostic markers of disease. © 2015 The Association for the Publication of the Journal of Internal Medicine.

Detection of specific IgE antibodies to major and minor antigenic determinants in sera of penicillin allergic patients.

To investigate the mechanism(s) of penicillins allergic reaction. The radioallergosorbent test (RAST) was used to detect 9 specific IgE antibodies, including major antigenic determinants: benzylpenicilloyl (BPO), ampicilloyl (APO), amoxicilloyl (AXO), phenoxomethylpenicilloyl (PVO) and flucloxacilloyl (FLUO), and minor antigenic determinants: benzylpenicillanyl (BPA), amoxicillanyl (AXA), 6-aminopenicillanic (APA) and phenoxomethylpenicillany (PVA), in the sera of 32 penicillin allergic patients. The relationship between specific IgE antibodies and penicillins chemical structures was studied by radioallergosorbent inhibition test. Nineteen of 32 patients (59.4%) were RAST positive, among whom, five cases were positive only to one or two antigenic minor determinants, and three cases were positive only to one or three major antigenic determinants. The remaining 11 patients were positive not only to major antigenic determinants but also minor antigenic determinants. In 9 specific IgE antibodies, the positive rate of PVA-IgE was the highest (34.38%), followed by BPO-IgE (31.25%). The positive rate of FLUO-IgE was the lowest (15.63%). Of the total patient group, 53.13% were positive to one or more minor antigenic determinants, while 37.5% (12/32) were positive to one or more major antigenic determinants. The percentage of patients with urticarial reactions who were positive to minor antigenic determinants (63.16%) was significantly higher than observed in the anaphylactic shock group (38.5%, P < 0.05). The minor antigenic determinant was important in allergic reaction. The combining sites of the specific IgE antibodies were likely to be the side-chain of drug or the overwhelming drug molecule.

There is a need to identify individual treatment success in patients with fibromyalgia (FM) who received non-pharmacological treatment. The present study described responder criteria for multicomponent non-pharmacological treatment in FM, and estimated and compared their sensitivity and specificity. Candidate responder sets were 1) identified in literature; and 2) formulated by expert group consensus. All candidate responder sets were tested in a cohort of 129 patients with FM receiving multicomponent non-pharmacological treatment. We used two gold standards (both therapist's and patient's perspective), assessed at six months after the start of treatment. Seven responder sets were defined (three identified in literature and four formulated by expert group consensus), and comprised combinations of domains of 1) pain; 2) fatigue; 3) patient global assessment (PGA); 4) illness perceptions; 5) limitations in activities of daily living (ADL); and 6) sleep. The sensitivity and specificity of literature-based responder sets (n=3) ranged between 17%-99% and 15%-95% respectively, whereas the expert-based responder sets (n=4) performed slightly better with regard to sensitivity (range 41%-81%) and specificity (range 50%-96%). Of the literature-based responder sets the OMERACT-OARSI responder set with patient's gold standard performed best (sensitivity 63%, specificity 75% and ROC area = 0.69). Overall, the expert-based responder set comprising the domains illness perceptions and limitations in ADL with patient's gold standard performed best (sensitivity 47%, specificity 96% and ROC area = 0.71). We defined sets of responder criteria for multicomponent non-pharmacological treatment in fibromyalgia. Further research should focus on the validation of those sets with acceptable performance.

In Massachusetts, physician groups' performance on validated surveys of patient experience has been publicly reported since 2006. Groups also receive detailed reports of their own performance, but little is known about how physician groups have responded to these reports. To examine whether and how physician groups are using patient experience data to improve patient care. During 2008, we conducted semi-structured interviews with the leaders of 72 participating physician groups (out of 117 groups receiving patient experience reports). Based on leaders' responses, we identified three levels of engagement with patient experience reporting: no efforts to improve (level 1), efforts to improve only the performance of low-scoring physicians or practice sites (level 2), and efforts to improve group-wide performance (level 3). Groups' level of engagement and specific efforts to improve patient care. Forty-four group leaders (61%) reported group-wide improvement efforts (level 3), 16 (22%) reported efforts to improve only the performance of low-scoring physicians or practice sites (level 2), and 12 (17%) reported no performance improvement efforts (level 1). Level 3 groups were more likely than others to have an integrated medical group organizational model (84% vs. 31% at level 2 and 33% at level 1; P < 0.005) and to employ the majority of their physicians (69% vs. 25% and 20%; P < 0.05). Among level 3 groups, the most common targets for improvement were access, communication with patients, and customer service. The most commonly reported improvement initiatives were changing office workflow, providing additional training for nonclinical staff, and adopting or enhancing an electronic health record. Despite statewide public reporting, physician groups' use of patient experience data varied widely. Integrated organizational models were associated with greater engagement, and efforts to enhance clinicians' interpersonal skills were uncommon, with groups predominantly focusing on office workflow and support staff.

This work aims to elucidate the effects of age and HIV-1 infection on the frequency and function of T cell subsets in response to HIV-specific and non-specific stimuli. As compared with the younger AIDS group, the frequencies of naive and central memory T cells were significantly lower in aged AIDS patients. Although there was also a dramatic loss of classical CD4(+)FoxP3(+)CD25(+)Treg cells in this patient group, high frequencies of IL-10-producing CD4(+)FoxP3(-) T cells were observed. In our system, the increased production of IL-10 in aged AIDS patients was mainly derived from Env-specific CD4(+)FoxP3(-)CD152(+) T cells. Interestingly, while the blockade of IL-10 activity by monoclonal antibody clearly enhanced the release of IL-6 and IL-1β by Env-stimulated PBMC cultures from aged AIDS patients, this monoclonal antibody enhanced in vitro HIV-1-replication. In conclusion, HIV infection and aging undoubtedly contribute synergistically to a complex immune dysfunction in T cell compartment of HAART-treated older HIV-infected individuals.

KBG syndrome is a neurodevelopmental disorder (NDD) caused by loss-of-function of the ANKRD11 gene. The core phenotype comprises developmental delay (DD)/ intellectual disability (ID) and several specific facial dysmorphisms. In addition, both ADHD- and ASD-related symptoms have been mentioned. For the correct understanding of these developmental and behavioral characteristics however, it is of great importance to apply objective measures, which seldom has been done in patients with KBG syndrome. In this study, intelligence profiles of patients with KBG syndrome (n = 18) were compared with a control group comprising patients with NDD caused by various other genetic defects (n = 17), by means of the Wechsler scales. These scales were also used to measure speed of information processing, working memory, verbal comprehension and perceptual reasoning. No significant differences were found in the global level of intelligence of patients with KBG syndrome as compared to the patient genetic control group. The same was true for Wechsler subtest results. Hence, behavioral problems associated with KBG syndrome cannot directly be related to or explained by a specific intelligence profile. Instead, specific assessment of neurocognitive functions should be performed to clarify the putative behavioral problems as observed in this syndrome. PMID:29311865

Traumas are the third most common cause of death worldwide, after cardiovascular diseases and neoplasms, and the main cause of death of patients under 40 years of age. Contemporary image diagnosis of chest trauma uses chest X-ray (CXR), multidetector computed tomography (MDCT), transthoracic and transoesophageal ultrasound (USG), X-ray angiography and magnetic resonance. The aim of the present study was to evaluate MDCT results in the examination of posttraumatic chest injuries and to compare the results of CXR and MDCT in chosen chest traumatic injuries. The sixty patients with chest trauma included in the study were diagnosed at the Department of Radiology of the Institute of Tuberculosis and Lung Diseases between May 2004 and October 2007. MDCT was performed in all patients. Two groups with different types of injury (blunt or penetrating chest trauma) were distinguished. The analysis of injuries in both groups was conducted depending on the mechanism of trauma. The detection of 20 selected injuries at CXR and MDCT was compared. Moreover, the compatibility of MDCT with the results of intraoperative assessment and bronchoscopy was analysed. The influence of MDCT on the treatment modality was also assessed. History of blunt chest trauma was found in 51 patients (group 1) and of penetrating trauma in 9 patients (group 2). The most frequent injuries among group 1 were lung contusion and rib fractures, and among group 2 it was pericardial hematoma. Compared to MDCT, the sensitivity and specificity of CXR were 66.7 and 58%, respectively. Change of treatment modality was observed after MDCT in 83% of patients. The sensitivity and specificity of MDCT in diagnosing tracheobronchial injury, compared to bronchoscopy, were 72.7% and 100%, respectively. Compatibility of MDCT results and intraoperative assessment was observed in 43% of patients, and the main reason for discrepancy was underdiagnosis of diaphragm injury in MDCT. MDCT was a valuable diagnostic method in recognition of chest trauma, characterized by high sensitivity and specificity in the assessment of life-threatening injures and for depicting tracheal and bronchial injuries. The diagnostic value of CXR was low. The compatibility of MCTD and intraoperative assessment was confirmed, with the exception of diaphragm injures and lung laceration. Change of treatment modality was certified after MDCT in 83% of patients.

The purpose of this archival study was to identify performance validity tests (PVTs) and standard IQ and neurocognitive test scores, which singly or in combination, differentiate credible patients of low IQ (FSIQ ≤ 75; n = 55) from non-credible patients. We compared the credible participants against a sample of 74 non-credible patients who appeared to have been attempting to feign low intelligence specifically (FSIQ ≤ 75), as well as a larger non-credible sample (n = 383) unselected for IQ. The entire non-credible group scored significantly higher than the credible participants on measures of verbal crystallized intelligence/semantic memory and manipulation of overlearned information, while the credible group performed significantly better on many processing speed and memory tests. Additionally, credible women showed faster finger-tapping speeds than non-credible women. The credible group also scored significantly higher than the non-credible subgroup with low IQ scores on measures of attention, visual perceptual/spatial tasks, processing speed, verbal learning/list learning, and visual memory, and credible women continued to outperform non-credible women on finger tapping. When cut-offs were selected to maintain approximately 90% specificity in the credible group, sensitivity rates were highest for verbal and visual memory measures (i.e., TOMM trials 1 and 2; Warrington Words correct and time; Rey Word Recognition Test total; RAVLT Effort Equation, Trial 5, total across learning trials, short delay, recognition, and RAVLT/RO discriminant function; and Digit Symbol recognition), followed by select attentional PVT scores (i.e., b Test omissions and time to recite four digits forward). When failure rates were tabulated across seven most sensitive scores, a cut-off of ≥ 2 failures was associated with 85.4% specificity and 85.7% sensitivity, while a cut-off of ≥ 3 failures resulted in 95.1% specificity and 66.0% sensitivity. Results are discussed in light of extant literature and directions for future research.

The rationale for neoadjuvant chemoradiation therapy (Neo-CRT) and the definition of borderline resectable pancreatic cancer (BRPC) are still controversial. In particular, surgical treatment of BRPC with isolated venous vascular involvement (IVVI) is debatable.From January 2000 to December 2013, 84 patients diagnosed with BRPC according to NCCN guidelines were identified, and 70 patients were found to have BRPC with IVVI. We divided all 70 patients into 3 groups: surgery first without Neo-CRT (Group 1); pancreatectomy following Neo-CRT (Group 2); and no operation following Neo-CRT (Group 3). Patient characteristics including oncologic outcomes were analyzed for each of the 3 patients groups.Thirty-seven patients were female and 33 were male, with a mean age of 61.7 ± 9.74 years. Among the 70 BRPC patients with IVVI, 28 patients (40%) belonged to Group 1, 30 patients (42.9%) belonged to Group 2, and 12 patients (17.1%) belonged to Group 3. Pathological tumor size (P < 0.001), pT stage (P = 0.001), pTNM stage (P=0.002), combined vascular resection (P = 0.003), completeness of adjuvant therapy (P = 0.004) were found to be statistically significantly different between Groups 1 and 2. In addition, disease-free survival (P = 0.055) and disease-specific survival (DSS) (P=0.006) were improved in Group 2. Interestingly, when comparing DSS, there was no statistically significant difference between Groups 1 and 3 (P = 0.991).The clinical practice of pancreatectomy following Neo-CRT in BRPC with IVVI provided favorable oncologic outcomes. The effect of Neo-CRT in BRPC with IVVI may be multifactorial, providing proper patient selection, complete adjuvant chemotherapy, and potential therapeutic (downstaging) effect.

Autobiographical memory specificity in dissociative identity disorder.

2014-05-01

A lack of adequate access to autobiographical knowledge has been related to psychopathology. More specifically, patients suffering from depression or a history of trauma have been found to be characterized by overgeneral memory, in other words, they show a relative difficulty in retrieving a specific event from memory located in time and place. Previous studies of overgeneral memory have not included patients with dissociative disorders. These patients are interesting to consider, as they are hypothesized to have the ability to selectively compartmentalize information linked to negative emotions. This study examined avoidance and overgeneral memory in patients with dissociative identity disorder (DID; n = 12). The patients completed the autobiographical memory test (AMT). Their performance was compared with control groups of posttraumatic stress disorder (PTSD) patients (n = 26), healthy controls (n = 29), and DID simulators (n = 26). Specifically, we compared the performance of separate identity states in DID hypothesized to diverge in the use of avoidance as a coping strategy to deal with negative affect. No significant differences in memory specificity were found between the separate identities in DID. Irrespective of identity state, DID patients were characterized by a lack of memory specificity, which was similar to the lack of memory specificity found in PTSD patients. The converging results for DID and PTSD patients add empirical evidence for the role of overgeneral memory involved in the maintenance of posttraumatic psychopathology.

To assess the effects of short-term resistance training and pulsed electromagnetic fields on bone metabolism and joint function in patients with haemophilia with osteoporosis. A randomized, controlled, patient and blood sample assessor-blinded, six-week trial, three times weekly. Hospital outpatients with severe haemophilia A and osteoporosis. Forty-eight patients were randomly assigned to resistance training (RT, n = 13), combined resistance training with pulsed electromagnetic fields (RTPEMF, n = 12), pulsed electromagnetic fields (PEMF, n = 11) and control (n = 12) groups. The RT group received 30-40 minutes of resistance exercises and placebo pulsed electromagnetic fields. The RTPEMF group received the same exercises with lower repetition and 30 minutes of pulsed electromagnetic fields. The PEMF group was exposed to 60 minutes of pulsed electromagnetic fields (30 Hz and 40 Gauss). Bone-specific alkaline phosphatase, N-terminal telopeptide of type 1 collagen, and joint function, using the modified Colorado Questionnaire, were measured before and after the programme. The absolute change of bone-specific alkaline phosphatase was significant in the RT and RTPEMF groups compared with the control group (25.41 ± 14.40, 15.09 ± 5.51, and -4.73 ± 2.93 U/L, respectively). The absolute changes in the total score for joint function were significant for knees, ankles, and elbows in the RT group (9.2 ± 1.38, 5.1 ± 0.5, and 3.2 ± 0.8, respectively) and the RTPEMF group (7.7 ± 1.0, 3.3 ± 0.6, and 2.5 ± 0.7, respectively) compared to the PEMF and control groups. This value was significant for knee joints in the PEMF group compared to the control group (3.4 ± 0.5 and 0.66 ± 0.4, respectively). Resistance training is effective for improving bone formation and joint function in severe haemophilia A patients with osteoporosis.

The DISC (Diabetes in Social Context) Study-evaluation of a culturally sensitive social network intervention for diabetic patients in lower socioeconomic groups: a study protocol

Background Compared to those in higher socioeconomic groups, diabetic patients in lower socioeconomic groups have less favourable metabolic control and experience more diabetes-related complications. They encounter specific barriers that hinder optimal diabetes self-management, including a lack of social support and other psychosocial mechanisms in their immediate social environments. Powerful Together with Diabetes is a culturally sensitive social network intervention specifically targeted to ethnic Dutch, Moroccan, Turkish, and Surinamese diabetic patients in lower socioeconomic groups. For ten months, patients will participate in peer support groups in which they will share experiences, support each other in maintaining healthy lifestyles, and learn skills to resist social pressure. At the same time, their significant others will also receive an intervention, aimed at maximizing support for and minimizing the negative social influences on diabetes self-management. This study aims to test the effectiveness of Powerful Together with Diabetes. Methods/Design We will use a quasi-experimental design with an intervention group (Group 1) and two comparison groups (Groups 2 and 3), N = 128 in each group. Group 1 will receive Powerful Together with Diabetes. Group 2 will receive Know your Sugar, a six-week group intervention that does not focus on the participants' social environments. Group 3 receives standard care only. Participants in Groups 1 and 2 will be interviewed and physically examined at baseline, 3, 10, and 16 months. We will compare their haemoglobin A1C levels with the haemoglobin A1C levels of Group 3. Main outcome measures are haemoglobin A1C, diabetes-related quality of life, diabetes self-management, health-related, and intermediate outcome measures. We will conduct a process evaluation and a qualitative study to gain more insights into the intervention fidelity, feasibility, and changes in the psychosocial mechanism in the participants' immediate social environments. Discussion With this study, we will assess the feasibility and effectiveness of a culturally sensitive social network intervention for lower socioeconomic groups. Furthermore, we will study how to enable these patients to optimally manage their diabetes. This trial is registered in the Dutch Trial Register: NTR1886 PMID:22429263

Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A) and delayed (B) cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient's satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient's satisfaction was 92.66 ± 6.8 in group A compared with 75.34 ± 12.85 in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

In France, teenagers with cancer are managed mainly in paediatric units, given that there are only few teenage cancer units. This situation leads to the following question: are teenagers with cancer provided with tailored patient education? The object of this study was to identify education programmes specifically designed for teenagers in French paediatric oncology units. This study was conducted first by questionnaires, second by interviews with health care providers in units where information programs had been implemented. Nine information programmes or projects were identified: 2 booklets, one log book, one Web chat, one video, one DVD, one educative muppet, one peer based education group project, one nursing education session project and one qualitative study project. Only 5 from these programmes or project were specifically designed for teenagers. Four approaches can be identified: conception of education materials, individual patient education, group patient education, informal patient education.

Transgender patients have particular needs with respect to demographic information and health records; specifically, transgender patients may have a chosen name and gender identity that differs from their current legally designated name and sex. Additionally, sex-specific health information, for example, a man with a cervix or a woman with a prostate, requires special attention in electronic health record (EHR) systems. The World Professional Association for Transgender Health (WPATH) is an international multidisciplinary professional association that publishes recognized standards for the care of transgender and gender variant persons. In September 2011, the WPATH Executive Committee convened an Electronic Medical Records Working Group comprised of both expert clinicians and medical information technology specialists, to make recommendations for developers, vendors, and users of EHR systems with respect to transgender patients. These recommendations and supporting rationale are presented here. PMID:23631835

Although bipolar disorder and substance use disorder frequently co-occur, there is little information on the effectiveness of behavioral treatment for this population. Integrated group therapy, which addresses the two disorders simultaneously, was compared with group drug counseling, which focuses on substance use. The authors hypothesized that patients receiving integrated group therapy would have fewer days of substance use and fewer weeks ill with bipolar disorder. A randomized controlled trial compared 20 weeks of integrated group therapy or group drug counseling with 3 months of posttreatment follow-up. Sixty-two patients with bipolar disorder and current substance dependence, treated with mood stabilizers for >or=2 weeks, were randomly assigned to integrated group therapy (N=31) or group drug counseling (N=31). The primary outcome measure was the number of days of substance use. The primary mood outcome was the number of weeks ill with a mood episode. Intention-to-treat analysis revealed significantly fewer days of substance use for integrated group therapy patients during treatment and follow-up. Groups were similar in the number of weeks ill with bipolar disorder during treatment and follow-up, although integrated group therapy patients had more depressive and manic symptoms. Integrated group therapy, a new treatment developed specifically for patients with bipolar disorder and substance dependence, appears to be a promising approach to reduce substance use in this population.

To cross-culturally adapt the VISA-P questionnaire for Greek-speaking patients and evaluate its psychometric properties. The VISA-P was developed in the English language to evaluate patients with patellar tendinopathy. The validity and use of self-administered questionnaires in different language and cultural populations require a specific procedure in order to maintain their content validity. The VISA-P questionnaire was translated and cross-culturally adapted according to specific guidelines. The validity and reliability were tested in 61 healthy recreational athletes, 64 athletes at risk from different sports, 32 patellar tendinopathy patients and 30 patients with other knee injuries. Participants completed the questionnaire at baseline and after 15-17 days. The questionnaire's face and content validity were judged as good by the expert committee, and the participants. Concurrent validity was almost perfect (ρ=-0.839, p<0.001). Also, factorial validity testing revealed a two-factor solution, which explained 85.6% of the total variance. A one-factor solution explained 80.8% of the variance when the other knee injury group was excluded. Known group validity was demonstrated by significant differences between patients compared with the asymptomatic groups (p<0.001). The VISA-P-GR exhibited very good test-retest reliability (ICC=0.818, p<0.001; 95% CI 0.758 to 0.864) and internal consistency since Cronbach's α analysis ranged from α=0.785 to 0.784 following a 15-17 days interval. The translated VISA-P-GR is a valid and reliable questionnaire and its psychometric properties are comparable with the original and adapted versions. Published by the BMJ Publishing Group Limited.

Cross-sectional design. To investigate whether the Fly Test can be used to differentiate patients with whiplash-associated disorders (WAD) from asymptomatic persons who deliberately feign symptoms and from WAD patients exaggerating symptoms. The lack of valid clinical tests makes it difficult to detect a justifiable cause for compensation claims in traumatic neck-pain disorders. The Fly Test recorded the accuracy of neck movements in patients with WAD (n = 34) and asymptomatic persons (n = 31). The participants followed a moving "Fly" on a computer screen with a cursor from sensors mounted on the head. Two conditions were tested, sincere versus feigned efforts. In the former, the participants moved their neck as accurately as possible. In the latter, a short text was presented describing a fictitious accident (asymptomatic group) or imagining more intense pain/suffering (WAD group), and the test was performed as affected by these more serious conditions. Amplitude accuracy (AA), time on target (ToT) and jerk index (JI) were compared across patterns, conditions and groups. The sincere effort in the WAD group was significant compared to the feigned effort of the asymptomatic group (p < 0.001). For AA, correct categorization of 81.5% of the performances was made, where a mean score above 5.5 mm differentiated feigned versus sincere efforts in asymptomatic and WAD groups (sensitivity 79.4%, specificity 67.7%). For ToT, score above 11% indicated correctly categorized WAD patients (sensitivity 82.4%, specificity 64.5%). The Fly Test can provide clinicians a clue when patients with mild to moderate pain/disability are feigning or exaggerating symptoms.

To observe nailfold capillary changes in a cohort of connective tissue disease (CTD) with Raynaud's phenomenon (RP) and to explore the diagnostic value of nailfold video-capillaroscopy (NVC) in systemic sclerosis (SSc). Sixty CTD patients with RP divided into SSc group (n = 36) and non-SSc group (n = 24) were referred to an experienced operator for NVC. The patients had decreased capillary loops in SSc group with the capillary diameter more enlarged in SSc group than non-SSc group. The number of patients in SSc group with giant capillaries was 14, while 3 in non-SSc group. There were 23 patients with haemorrhages in SSc group and 9 in non-SSc group. The number of patients with severe effusion was 15 in SSc group, while 2 in non-SSc group. By using the ROC curves, indexes with AUC at least 0.7 of the input capillary diameter, the output capillary diameter, the middle capillary diameter, blood color and effusion for the diagnostic cutoff points were 18.5 µm, 24.5 µm, 19.5µm, deep red and severe effusion. With at least 2 out of the top 3 indexes, the diagnostic sensitivity and specificity of SSc were higher. CTD Patients with RP of SSc have less capillary loops, more enlarged capillaries, more giant capillaries, more severe effusion and more haemorrhages than non-SSc patients. The characteristics of nailfold capillary changes in SSc patients with RP can be helpful for the diagnosis and the differential diagnosis of SSc.

Urinary biomarkers of mycotoxin exposure were evaluated in a group of celiac patients (n = 55) and in a control group of healthy subjects (n = 50) following their habitual diet. Deoxynivalenol (DON), zearalenone (ZEN), and fumonisin B1 (FB1) were monitored in 105 urinary samples collected from the two groups. Dietary habits were also recorded through compilation of a seven-day weighed dietary diary. Biomarkers of mycotoxin exposure were detected in 21 celiac patients and in 15 control subjects, corresponding to about 34% of total participants. In particular, ZEN was the most detected mycotoxin among all the studied subjects with a total of 19 positive cases. Results did not show a statistically significant difference in mycotoxin exposure between the two groups, and the presence of specific mycotoxins was not related to the intake of any particular food category. Our findings suggest little urgency of specific regulation for gluten free products, although the prevalence of exposure observed in free-living diets of both celiac and healthy subjects underlines the need of a constant surveillance on mycotoxins occurrence at large.

Purpose: The optimal sequence of radiotherapy and chemotherapy in breast-conserving therapy is unknown. Methods and Materials: From 1983 through 2007, a total of 641 patients with 653 instances of breast-conserving therapy (BCT), received both chemotherapy and radiotherapy and are the basis of this analysis. Patients were divided into three groups. Groups A and B comprised patients treated before 2005, Group A radiotherapy first and Group B chemotherapy first. Group C consisted of patients treated from 2005 onward, when we had a fixed sequence of radiotherapy first, followed by chemotherapy. Results: Local control did not show any differences among the threemore » groups. For distant metastasis, no difference was shown between Groups A and B. Group C, when compared with Group A, showed, on univariate and multivariate analyses, a significantly better distant metastasis-free survival. The same was noted for disease-free survival. With respect to disease-specific survival, no differences were shown on multivariate analysis among the three groups. Conclusion: Radiotherapy, as an integral part of the primary treatment of BCT, should be administered first, followed by adjuvant chemotherapy.« less

A doctor's ability to communicate effectively is key to establishing and maintaining positive doctor-patient relationships. The Consumer Assessment of Healthcare Providers and System (CAHPS(®)) Clinician and Group Survey is the standard for collecting and reporting information about patients' experiences of care in the USA. To evaluate how well CAHPS(®) Clinician and Group 2.0 core and supplemental survey items (CG-CAHPS) with a 12-month reference capture doctor-patient communication. Eleven of the 40 highest-rated physicians on the CG-CAHPS survey treating patients in a Midwest commercial health plan. Data were obtained via semi-structured interviews. Specific behaviors, practices, and opinions about doctor communication were coded and compared to the CG-CAHPS items. CG-CAHPS fully captures six of the nine behaviors most commonly mentioned by high-performing physicians: employing office staff with good people skills; involving office staff in communication with patients; spending enough time with patients; listening carefully; providing clear, simple explanations; and devising an action plan with each patient. Three physician behaviors identified as key were not captured in CG-CAHPS items: use of nonverbal communication; greeting patients and introducing oneself; and tracking personal information about patients. CG-CAHPS survey items capture many of the most commonly mentioned doctor-patient communication behaviors and practices identified by high-performing physicians. Nonverbal communication, greeting patients, and tracking personal information about patients were identified as key aspects of doctor-patient communication, but are not captured by the current CG-CAHPS. We recommend further research to assess patients' perceptions of specific verbal and nonverbal behaviors (such as leaning forward in a chair, casually asking about other family members), followed by the development of new items (if needed) that aim to capture what these specific behaviors represent to patients (e.g., listens attentively, seems to care about me as a person, empathy). We also recommend including items about greeting and tracking personal information about patients in future CAHPS item sets addressing doctor-patient communication. Enriching the content of the CAHPS communication measure can help health-care organizations improve doctor-patient communication and interactions.

This research investigated the information needs of patients receiving ED procedural sedation to determine the best format to consistently deliver key information in a way acceptable to all involved. Of particular interest was the question concerning patients' need for receiving written information. A descriptive exploratory study gathered qualitative data through face-to-face interviews and focus groups involving patients, nurses and medical staff. Individual interviews were conducted with eight adult patients following procedural sedation. They identified very few gaps in terms of specific information they needed pertaining to procedural sedation and rejected the need for receiving information in a written format. Their information needs related to a central concern for safety and trust. Focus groups, reflecting on the findings from patients, were conducted with five ED nurses and four emergency medicine consultants/registrars who regularly provided procedural sedation. Themes that emerged from the analysis of data from all three groups identified the issues concerning patient information needs as being: competence and efficiency of staff; explanations of procedures and progress; support person presence; and medico-legal issues. The research confirms that the quality of the patient's ED experience, specifically related to procedural sedation, is enhanced by ED staff, especially nurses, providing them with ongoing and repeated verbal information relevant to their circumstances.

This study investigated the fear of progression (FoP) in cancer patients and the discriminant ability of the Fear of Progression Questionnaire (FoP-Q) against the Hospital Anxiety and Depression Scale (HADS), while also examining relationships between FoP, satisfaction outcomes and supportive needs. The FoP-Q and HADS were administered to 112 cancer patients in Korea during June and July 2006. The FoP-Q totals and subscales, and the HADS scores were compared across three groups (patients with recurrence, patients with metastases and controls experiencing neither). Comparison of the FoP-Q total score to HADS anxiety (HADS-A) and depression (HADS-D) scores showed higher FoP in the recurrence group compared to the control group (P=.009). Subscale score comparisons revealed a heightened "affective reaction" (P=.003) to cancer progression and fear of "loss of autonomy" (P=.011) in recurrence patients. FoP-Q score showed a moderate association with HADS-A (r=.54, P=.000) and a significant association with treatment satisfaction (r=-.26, P=.007), medical staff and communication (r=-.31, P=.001), and supportive needs (r=.41, P=.000). The importance of providing supportive interventions tailored to the specific emotional concerns of cancer patients, assessed via appropriate, disease-specific instruments, and the need to pay special attention to the concerns of recurrence patients are suggested.

ABSTRACT Objective To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. Methods A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. Results The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Conclusion Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone. PMID:28767914

Electroconvulsive therapy (ECT) is a highly effective and well-tolerated therapy for severe and treatment-resistant depression. Cognitive side-effects are still feared by some patients and clinicians. Importantly, cognitive impairments are among the most disabling symptoms of depression itself. Patients suffering from a severe episode of depression were treated with either ECT or treatment as usual (TAU) in an in-patient setting. Matched healthy participants served as controls (HC). Verbal memory was tested with the California Verbal Learning Test (CVLT) before the specific treatment started (ECT = 15, TAU = 16, HC = 31) and 2 months after the last ECT session or 2 months after discharge respectively. Before the specific treatment started, depressed patients performed substantially worse compared with HC in total, short- and long-delay recall in the CVLT, while the ECT group showed the worst performance. More severely depressed patients showed worse performances in these measures. Intriguingly, verbal memory showed a significant improvement in ECT-treated patients, but not in the other groups. No differences between the groups were found at follow-up. Contrary to the widely feared assumption that ECT has long-term impact on memory functions, we found evidence that ECT is superior to TAU in improving verbal memory in depressed patients. © 2016 John Wiley & Sons A/S.

Condyle-specific matching for osteochondral allograft transplantation (OCA) pairs donor and recipient condyles in an attempt to minimize articular incongruity. While the majority of cartilage defects are located on the medial femoral condyle, lateral femoral condyles are more commonly available as a graft source. The purpose of this study was to compare the clinical outcomes of patients treated with non-orthotopic (lateral-to-medial condyle or medial-to-lateral condyle) OCA with those treated with traditional orthotopic (medial-to-medial condyle or lateral-to-lateral condyle) OCA. We hypothesized that clinical outcomes would be similar between groups at midterm follow-up. A retrospective review of prospectively collected data on patients treated with OCA from 2000 to 2014 was conducted. Seventy-seven patients with a full-thickness cartilage defect of a femoral condyle were treated with either orthotopic (n = 50) or non-orthotopic (n = 27) OCA. A minimum follow-up of 2 years was required for analysis. Patients in each group were matched according to sex, age, and total chondral defect size. Reoperations and patient responses to validated outcome measures were reviewed. Failure was defined as any revision cartilage procedure or conversion to knee arthroplasty. The mean duration of follow-up was 4.0 years (range, 2 to 16 years). The orthotopic and non-orthotopic OCA groups were comparable in terms of demographics, the mean number of prior ipsilateral knee operations, and the percentage of concomitant procedures at baseline. Reoperation (p = 0.427) and failure (p = 0.917) rates did not differ significantly between groups. Both groups demonstrated significant increases in the Short Form-36 (SF-36) physical functioning and pain, International Knee Documentation Committee (IKDC), and Knee Outcome Survey-Activities of Daily Living (KOS-ADL) scores compared with baseline (p < 0.004). Outcome scores (baseline and postoperative) and change scores did not differ significantly between groups. Clinical outcomes do not differ between patients treated with orthotopic OCA and those treated with non-orthotopic OCA, suggesting that condyle-specific matching may not be necessary.

To assess the communication potential of three-dimensional (3D) patient-specific models of congenital heart defects and their acceptability in clinical practice for cardiology consultations. This was a questionnaire-based study in which participants were randomised into two groups: the 'model group' received a 3D model of the cardiac lesion(s) being discussed during their appointment, while the 'control group' had a routine visit. Outpatient clinic, cardiology follow-up visits. 103 parents of children with congenital heart disease were recruited (parental age: 43±8 years; patient age: 12±6 years). In order to have a 3D model made, patients needed to have a recent cardiac MRI examination; this was the crucial inclusion criterion. Questionnaires were administered to the participants before and after the visits and an additional questionnaire was administered to the attending cardiologist. Rating (1-10) for the liking of the 3D model, its usefulness and the clarity of the explanation received were recorded, as well as rating (1-10) of the parental understanding and their engagement according to the cardiologist. Furthermore, parental knowledge was assessed by asking them to mark diagrams, tick keywords and provide free text answers. The duration of consultations was recorded and parent feedback collected. Parents and cardiologists both found the models to be very useful and helpful in engaging the parents in discussing congenital heart defects. Parental knowledge was not associated with their level of education (p=0.2) and did not improve following their visit. Consultations involving 3D models lasted on average 5 min longer (p=0.02). Patient-specific models can enhance engagement with parents and improve communication between cardiologists and parents, potentially impacting on parent and patient psychological adjustment following treatment. However, in the short-term, parental understanding of their child's condition did not improve. Published by the BMJ Publishing Group Limited.

Objective This study was aimed to compare survival outcomes in high-risk prostate cancer (PCa) patients receiving external beam radiotherapy (EBRT) or radical prostatectomy (RP). Materials and methods The Surveillance, Epidemiology, and End Results (SEER) database was used to identify PCa patients with high-risk features who received RP alone or EBRT alone from 2004 to 2008. Propensity-score matching (PSM) was performed. Kaplan–Meier survival analysis was used to compare cancer-specific survival (CSS) and overall survival (OS). Multivariate Cox regression analysis was used to identify independent prognostic factors. Results A total of 24,293 patients were identified, 14,460 patients receiving RP and 9833 patients receiving EBRT. Through PSM, 3828 patients were identified in each group. The mean CSS was 128.6 and 126.7 months for RP and EBRT groups, respectively (P<0.001). The subgroup analyses showed that CSS of the RP group was better than that of the EBRT group for patients aged <65 years (P<0.001), White race (P<0.001), and married status (P<0.001). However, there was no significant difference in CSS for patients aged ≥65 years, Black race, other race, and unmarried status. Similar trends were observed for OS. Multivariate analysis showed that EBRT treatment modality, T3–T4 stage, Gleason score 8–10, and prostate-specific antigen >20 ng/mL were significant risk factors for both CSS and OS. Conclusion This study suggested that survival outcomes might be better with RP than EBRT in high-risk PCa patients aged <65 years; however, RP and EBRT provided equivalent survival outcomes in older patients, which argues for primary radiotherapy in this older cohort.

Patients with negative anti-Helicobacter pylori antibody titer and high pepsinogen (PG) level (group A) are regarded as having a low risk for gastric cancer. However, gastric cancer cases are occasionally observed in this group. We aimed to elucidate the clinical features of gastric neoplasm in group A patients and reviewed advanced methods for mass screening. A total of 271 gastric epithelial neoplasm patients were enrolled. We classified them according to the H. pylori-PG system and determined the number of patients in each group. After excluding true H. pylori-negative cases from group A (group A'), we examined the differences between group A' and group non-A. Group A included 30 (11%) patients, and only three of these were true negative for H. pylori. All patients in group A' (n = 27) exhibited endoscopic atrophy in the gastric corpus. Serologically, these patients showed low gastrin, low PG II and high PG I/II ratio, indicative of post-eradication. Histologically, 24 (89%) of these had little inflammation, and 26 (96%) were negative for H. pylori by immunohistochemistry. No difference was observed in the incidence of metachronous gastric tumors between group A' and group non-A. The discriminant function using gastrin and PGs could distinguish these 27 patients from true H. pylori-negative controls with 85% sensitivity and 84% specificity. Group A included a certain number of patients with atrophic gastritis who were potentially at risk of gastric neoplasm development. Although evaluation of corpus atrophy is necessary for the identification of these patients, the discriminant function may be useful. © 2013 John Wiley & Sons Ltd.

To investigate the real-time tissue elastography and 3D contrast-enhanced ultrasonography(CEUS) in breast lumps differential diagnostic value. A total of 126 patients (180 lumps) with breast mass were retrospectively analyzed from December 2012 to December 2014 in Tumor Hospital Affiliated To Xinjiang Medical University.All patients were divided into three groups by using stratified random method.Each group was detected by real-time tissue elastography, 3D CEUS and two joint inspection.Each group of 42 cases (60 lumps) was confirmed by the pathological results as gold standard.Diagnostic sensitivity, specificity and coincidence rate of different methods were compared. The benign masses of ultrasound contrast showed the punctate, linear and nodular enhancement, and the border of enhancement was smooth.The malignant tumors were mainly dominated by uneven and high enhancement. There was no statistical difference in sensitivity, specificity and coincidence rate between elastography group and 3D CEUS group (64.7% vs 73.5%, 69.2% vs 76.9%, 66.7% vs 75.0%, all P>0.05). The sensitivity, specificity and coincidence rate of two joint inspection group were higher than those of elastography group and 3D CEUS group, the differences were statistically significant (97.1%, 92.3% and 98.3% , all P<0.05). 3D CEUS combined with real-time tissue elastography is of high value in the diagnosis of breast masses.

Excellent communication is a necessary component of high-quality health care. We aimed to determine whether a training module could improve patients' perceptions of physician communication behaviors, as measured by change over time in domains of patient experience scores related to physician communication. We designed a comprehensive physician-training module focused on improving specific "etiquette-based" physician communication skills through standardized simulations and physician coaching with structured feedback. We employed a quasi-experimental pre-post design, with an intervention group consisting of internal medicine hospitalists and residents and a control group consisting of surgeons. The outcome was percent "always" scores for questions related to patients' perceptions of physician communication using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey and a Non-HCAHPS Physician-Specific Patient Experience Survey (NHPPES) administered to patients cared for by hospitalists. A total of 128 physicians participated in the simulation. Responses from 5020 patients were analyzed using HCAHPS survey data and 1990 patients using NHPPES survey data. The intercept shift, or the degree of change from pre-intervention percent "always" responses, for the HCAHPS questions of doctors "treating patients with courtesy" "explaining things in a way patients could understand," and "overall teamwork" showed no significant differences between surgical control and hospitalist intervention patients. Adjusted NHPPES percent excellent survey results increased significantly post-intervention for the questions of specified individual doctors "keeping patient informed" (adjusted intercept shift 9.9% P = 0.019), "overall teamwork" (adjusted intercept shift 11%, P = 0.037), and "using words the patient could understand" (adjusted intercept shift 14.8%, p = 0.001). A simulation based physician communication coaching method focused on specific "etiquette-based" communication behaviors through a deliberate practice framework was not associated with significantly improved HCAHPS physician communication patient experience scores. Further research could reveal ways that this model affects patients' perceptions of physician communication relating to specific physicians or behaviors.

Trauma patients: I can't get no (patient) satisfaction?

The Centers for Medicare and Medicaid Services (CMS) provides financial incentives to hospitals based on the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) patient satisfaction survey. This data is made publicly available on their website to be utilized by patients and insurers. Hospitals are profoundly interested in identifying patient populations that negatively contribute to overall patient satisfaction scores. Hospitals consider trauma patients "high risk" from a HCAHPS perspective, but there is no data to inform this opinion. The purpose of this study is to evaluate trauma patient satisfaction scores and their impact on overall patient satisfaction. Three different analyses were performed. Group 1 was composed of ALL patients admitted to our hospital over a 7-month period who were administered a validated patient satisfaction survey by a 3rd party and compared patient satisfaction of trauma vs. non-trauma patients (ALL). Group 2 compared admitted patients with a specific ICD-9 procedure code to non-trauma patients who underwent a procedure with the same ICD-9 code (ICD). Group 3 examines patient satisfaction between three Level I Trauma Centers within our geographic area (TC). Patient satisfaction data of trauma vs non-trauma patients (ALL), those with a specific ICD-9 procedure code (ICD), and the 3 Level I Trauma Centers in our area (TC) were analyzed with the appropriate statistical test. In the ALL group, no difference in satisfaction was noted in 18/21 questions for trauma patients when compared to non-trauma patients at our hospital. In the ICD group, 57 ICD-9 procedure codes were analyzed. Of these, only patients who required spinal fusion secondary to trauma reported lower overall patient satisfaction. No meaningful difference was found in HCAHPS associated satisfaction between the Level I Trauma Centers in our area (TC). In contrast to commonly held opinion, trauma patients do not negatively contribute to overall patient satisfaction in our facility. Certain injuries may offer opportunities for improvement and efforts around improved physician-patient communication may be warranted. In the era of public reporting and financial penalties, surgeons should embrace patient satisfaction as it may be vital to the survival of the trauma center. Copyright © 2016.

Inadequate assessment and management of pain among critical care patients can lead to ineffective care delivery and an increased length of stay. Nurses' lack of knowledge regarding appropriate assessment and treatment, as well as negative biases toward specific patient populations, can lead to poor pain control. Our aim was to evaluate the effectiveness of professionally directed small group discussions on critical care nurses' knowledge and biases related to pain management. A quasi-experiment was conducted at a 383-bed Magnet(®) redesignated hospital in the southeastern United States. Critical care nurses (N = 32) participated in the study. A modified Brockopp and Warden Pain Knowledge Questionnaire was administered before and after the small group sessions. These sessions were 45 minutes in length, consisted of two to six nurses per group, and focused on effective pain management strategies. Results indicated that mean knowledge scores differed significantly and in a positive direction after intervention [preintervention mean = 18.28, standard deviation = 2.33; postintervention mean = 22.16, standard deviation = 1.70; t(31) = -8.87, p < .001]. Post-bias scores (amount of time and energy nurses would spend attending to patients' pain) were significantly higher for 6 of 15 patient populations. The strongest bias against treating patients' pain was toward unconscious and mechanically ventilated individuals. After the implementation of professionally directed small group discussions with critical care nurses, knowledge levels related to pain management increased and biases toward specific patient populations decreased.

To assess the prevalence of possible risk factors of upper gastrointestinal bleeding (UGIB) and their age-group specific trend among the general population and osteoarthritis patients. We utilized data from the National Health Insurance Service that included claims data and results of the national health check-up program. Comorbid conditions (peptic ulcer, diabetes, liver disease, chronic renal failure, and gastroesophageal reflux disease), concomitant drugs (aspirin, clopidogrel, cilostazol, non-steroidal anti-inflammatory drugs, steroid, anticoagulants, and SSRI), personal habits (smoking, and alcohol consumption) were considered as possible UGIB risk factors. We randomly imputed the prevalence of infection in the data considering the age-specific prevalence of Helicobacter pylori ( H. pylori ) infection in Korea. The prevalence of various UGIB risk factors and the age-group specific trend of the prevalence were identified. Prevalence was compared between osteoarthritis patients and others. A total of 801926 subjects (93855 osteoarthritis patients) aged 20 and above were included. The prevalence of individual and concurrent multiple risk factors became higher as the age increased. The prevalence of each comorbid condition and concomitant drug were higher in osteoarthritis patients. Thirty-five point zero two percent of the overall population and 68.50% of osteoarthritis patients had at least one or more risk factors of UGIB. The prevalence of individual and concurrent multiple risk factors in younger age groups were also substantial. Furthermore, when personal habits (smoking, and alcohol consumption) and H. pylori infection were included, the prevalence of concurrent multiple risk factors increased greatly even in younger age groups. Prevalence of UGIB risk factors was high in elderly population, but was also considerable in younger population. Patient with osteoarthritis was at higher UGIB risk than those without osteoarthritis. Physicians should consider individualized risk assessment regardless of age when prescribing drugs or performing procedures that may increase the risk of UGIB, and take necessary measures to reduce modifiable risk factors such as H. pylori eradication or lifestyle counseling.

Antidepressant treatment efficacy is low, but might be improved by matching patients to interventions. At present, clinicians have no empirically validated mechanisms to assess whether a patient with depression will respond to a specific antidepressant. We aimed to develop an algorithm to assess whether patients will achieve symptomatic remission from a 12-week course of citalopram. We used patient-reported data from patients with depression (n=4041, with 1949 completers) from level 1 of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D; ClinicalTrials.gov, number NCT00021528) to identify variables that were most predictive of treatment outcome, and used these variables to train a machine-learning model to predict clinical remission. We externally validated the model in the escitalopram treatment group (n=151) of an independent clinical trial (Combining Medications to Enhance Depression Outcomes [COMED]; ClinicalTrials.gov, number NCT00590863). We identified 25 variables that were most predictive of treatment outcome from 164 patient-reportable variables, and used these to train the model. The model was internally cross-validated, and predicted outcomes in the STAR*D cohort with accuracy significantly above chance (64·6% [SD 3·2]; p<0·0001). The model was externally validated in the escitalopram treatment group (N=151) of COMED (accuracy 59·6%, p=0.043). The model also performed significantly above chance in a combined escitalopram-buproprion treatment group in COMED (n=134; accuracy 59·7%, p=0·023), but not in a combined venlafaxine-mirtazapine group (n=140; accuracy 51·4%, p=0·53), suggesting specificity of the model to underlying mechanisms. Building statistical models by mining existing clinical trial data can enable prospective identification of patients who are likely to respond to a specific antidepressant. Yale University.

The Pilates method has been widely used to treat patients with chronic low back pain. Pilates exercises can be performed in 2 ways: by using specific equipment or without it (also known as mat Pilates). There are no studies, however, that have compared the effectiveness of mat Pilates with that of equipment-based Pilates. The aim of this study was to compare the effectiveness of mat Pilates and equipment-based Pilates in patients with chronic nonspecific low back pain. A 2-arm randomized controlled trial with a blinded assessor was conducted. The study was conducted at a private physical therapy clinic in Brazil. Eighty-six patients with chronic nonspecific low back pain participated. The patients were randomly allocated to 1 of 2 groups: a mat Pilates group (n=43) and an equipment-based Pilates group (n=43). The participants in both groups attended 12 Pilates sessions over a period of 6 weeks. The primary outcomes were pain intensity and disability. The secondary outcomes were global perceived effect, patient's specific disability, and kinesiophobia. A blinded assessor evaluated the outcomes at baseline and 6 weeks and 6 months after randomization. After 6 months, there was a statistically significant difference for disability (mean difference=3.0 points, 95% confidence interval [CI]=0.6 to 5.4), specific disability (mean difference=-1.1 points, 95% CI=-2.0 to -0.1), and kinesiophobia (mean difference=4.9 points, 95% CI=1.6 to 8.2) in favor of equipment-based Pilates. No differences were found for the remaining outcomes. Equipment-based Pilates was superior to mat Pilates in the 6-month follow-up for the outcomes of disability and kinesiophobia. These benefits were not observed for pain intensity and global perceived effect in patients with chronic nonspecific low back pain.

Attentional bias to disease-relevant emotional cues is considered to be pathogenetically relevant in anxiety disorders. To investigate functional neural correlates and disease specificity of attentional bias across different anxiety disorders. A cognitive and emotional Stroop task, consisting of congruent and incongruent color words, obsessive-compulsive disorder (OCD)-related and panic-related negative words, and neutral words, was used in 3 patient groups and a control group during functional magnetic resonance imaging. Academic outpatient department for anxiety disorders. Medication-free patients with OCD (n = 16), panic disorder (PD) (n = 15), and hypochondriasis (n = 13) and 19 controls. Voxel-wise analyses of cerebral blood flow changes for contrasts of interest (incongruent vs congruent color words, OCD-related vs neutral words, and panic-related vs neutral words) within and between groups. During incongruent vs congruent color naming, all patient groups recruited additional posterior brain regions relative to controls, but performance was impaired only in OCD. In OCD, color naming OCD-related, but not PD-related, words correlated with increased activation of frontal-striatal and temporal regions, although performance was unimpaired. In contrast, in PD, increased frontal-striatal involvement was found during color naming both OCD-related and panic-related words. In PD, color naming panic-related words was slowed and correlated with increased activation of the right amygdala and hippocampus. Patients with hypochondriasis showed a similar activation pattern to patients with PD. Our results support the hypothesis of increased distractibility for irrelevant information in patients with OCD, PD, and hypochondriasis associated with frontal-striatal and limbic involvement compared with controls. Although patients with OCD did not display an attentional bias in behavior relative to controls, there was a clear, specific neural response during color naming OCD-related words, involving mainly ventral brain regions. In contrast, generalized emotional interference effects were found in PD and hypochondriasis, involving ventral and widespread dorsal brain regions, reflecting not only unconscious emotional stimulus processing but also increased cognitive elaboration.

Combined supine-prone myocardial perfusion imaging (CSP MPI) has been shown to reduce attenuation artifact in comparison to supine-only (SU) MPI in mixed-gender populations with varying risk for coronary artery disease (CAD), often where patients served as their own controls. However, there is limited direct comparison of these imaging strategies in men. 934 male patients underwent CSP or SU MPI. Diagnostic certainty of interpretation was compared. Within the cohort, 116 were referred for left heart catheterization (LHC) to assess for CAD. Sensitivity, specificity, and area under the curve (AUC) were compared with additional analysis based on body mass index (BMI). 597 patients completed the SU protocol and 337 patients completed the CSP protocol. Equivocal studies were seen more frequently in the SU group (13%) than in the CSP group (4%, P < .001). At catheterization, the specificity for CSP MPI of 70% was higher than 40% for SU MPI (P = .032). The CSP AUC (0.80 ± 0.06) was significantly larger than SU AUC (0.57 ± 0.05, P = .004). CSP specificity was significantly higher in obese patients. CSP MPI increases diagnostic certainty and improves test accuracy for CAD detection in men with CAD risk factors, especially obese patients, compared to SU MPI.

The prevalence of MLH1 constitutional epimutations in the general population is unknown. We sought to analyse the prevalence of MLH1 constitutional epimutations in unselected and selected series of patients with colorectal cancer (CRC). Patients with diagnoses of CRC (n=2123) were included in the unselected group. For comparison, a group of 847 selected patients with CRC who fulfilled the revised Bethesda guidelines (rBG) were also included. Somatic and constitutional MLH1 methylation was assayed via methylation-specific multiplex ligation-dependent probe amplification of cases lacking MLH1 expression. Germline alterations in mismatch-repair (MMR) genes were assessed via Sanger sequencing and methylation-specific multiplex ligation-dependent probe amplification. Loss of MLH1 expression occurred in 5.5% of the unselected series and 12.5% of the selected series (p<0.0001). No constitutional epimutations in MLH1 were detected in the unselected population (0/62); five cases from the selected series were positive for MLH1 epimutations (15.6%, 5/32; p=0.004). Our results suggest a negligible prevalence of MLH1 constitutional epimutations in unselected cases of CRC. Therefore, MLH1 constitutional epimutation analysis should be conducted only for patients who fulfil the rBG and who lack MLH1 expression with methylated MLH1.

Questionnaires to screen for rheumatoid arthritis (RA) have been tested in groups that were primarily well educated and Caucasian. We sought to validate the RA questions of the Connective Tissue Disease Screening Questionnaire (CSQ) in ethnic minorities in an underserved community, and to test a Spanish-language version. The Spanish-language version was developed by 2 native speakers. Consecutive English-speaking or Spanish-speaking patients in a community-based rheumatology practice completed the questionnaire. Diagnoses were confirmed by medical record review. Sensitivity and specificity of the questionnaire for a diagnosis of RA were computed for each language version, using 2 groups as controls: patients with noninflammatory conditions, and participants recruited from the community. The English-language version was tested in 53 patients with RA (79% ethnic minorities; mean education level 11.3 yrs), 85 rheumatology controls with noninflammatory conditions, and 82 community controls. Using 3 positive responses as indicating a positive screening test, the sensitivity of the questionnaire was 0.77, the specificity based on rheumatology controls was 0.45, and the specificity based on community controls was 0.94. The Spanish-language version was tested in 55 patients with RA (mean education level 7.8 yrs), 149 rheumatology controls, and 88 community controls. The sensitivity of the Spanish-language version was 0.87, with specificities of 0.60 and 0.97 using the rheumatology controls and community controls, respectively. The sensitivity of the English-language version of the RA questions of the CSQ was lower in this study than in other cohorts, reflecting differences in the performance of the questions in different ethnic or socioeconomic groups. The Spanish-language version demonstrated good sensitivity, and both had excellent specificity when tested in community controls.

This study was to follow IFN-γ, TNF-α and IL-10 modulation of peripheral blood mononuclear cells (PBMC) from HIV/cerebral toxoplasmosis patients (CT) during specific treatment. The results were compared with two other groups: HIV patients that had CT at least one year before (P/CT) and individuals with chronic toxoplasmosis (CHR). Blood samples (63) collected from three groups were analyzed. CT, 15 patients (3 blood samples collected one day before Toxoplasma gondii treatment; 7 and 15days during the treatment). P/CT, 5 patients (one blood sample collected at least, one year after the treatment). CHR, 13 individuals with chronic toxoplasmosis (one blood sample). Cytokine levels were assessed by ELISA after PBMC stimulation with T. gondii antigen. CT patients had low IFN-γ; discrete increase at 7th and 15th days; and the levels were recovered in cured patients (P/CT). CT patients had high TNF-α in the beginning of the treatment. TNF-α levels decrease during the treatment (7th and 15th) and in those patients who were treated (P/CT). IL-10 levels were almost similar in CT and P/CT groups but low when compared with CHR individuals. The evolution of the infection was correlated to restoration of IFN-γ response and a decrease of the inflammation. The evaluation of the immune response can provide valuable information and better monitoring of patients during specific treatment. Copyright © 2015 Elsevier B.V. All rights reserved.

Residents may view feedback from patients and their families with greater skepticism than feedback from supervisors and peers. While discussing patient and family feedback with faculty may improve residents' acceptance of feedback and learning, specific strategies have not been identified. We explored pediatrics residents' perspectives of patient feedback and identified strategies that promote residents' reflection on and learning from feedback. In this multi-institutional, qualitative study conducted in June and July 2016, we conducted focus groups with a purposive sample of pediatrics residents after their participation in a randomized controlled trial in which they received written patient feedback and either discussed it with faculty or reviewed it independently. Focus group transcripts were audiorecorded, transcribed, and analyzed for themes using the constant comparative approach associated with grounded theory. Thirty-six of 92 (39%) residents participated in 7 focus groups. Four themes emerged: (1) residents valued patient feedback but felt it may lack the specificity they desire; (2) discussing feedback with a trusted faculty member was helpful for self-reflection; (3) residents identified 5 strategies faculty used to facilitate their openness to and acceptance of patient feedback (eg, help resident overcome emotional responses to feedback and situate feedback in the context of lifelong learning); and (4) residents' perceptions of feedback credibility improved when faculty observed patient encounters and solicited feedback on the resident's behalf prior to discussions. Discussing patient feedback with faculty provided important scaffolding to enhance residents' openness to and reflection on patient feedback.

To evaluate the outcomes of conservatively managed staghorn calculi, specifically looking at morbidity and mortality, incidence of infections and progressive changes in renal function. A total of 22 patients with unilateral or bilateral staghorn calculi, who were treated conservatively, were included in the study. Patients were reviewed yearly with symptom assessment, urine culture and measurement of estimated glomerular filtration rate. The presentations to the urology department of staghorn calculi were incidental (41%), haematuria (36%), abdominal discomfort (5%) and recurrent urinary tract infections (UTIs; 18%). The reasons for conservative management in the cohort were comorbidities (59%), patient choice (36%) or poor access/anatomy (5%). In the whole cohort the rate of recurrent UTIs was 50%, the progressive renal failure rate was 14%, the disease-specific mortality rate was 9%, the dialysis dependence rate was 9% and the rate of hospital attendances attributable to stone-related morbidity was 27%. Comparison of outcome measures between the unilateral and bilateral staghorn stones showed statistically significant differences in disease-specific mortality (0 vs 40%) and morbidity (12 vs 80%) in favour of the unilateral group. Although there was a lower incidence of UTIs (41 vs 80%), renal deterioration (6 vs 40%) and dialysis requirement (6 vs 20%) in the unilateral group, these findings were not statistically significant. From the results, we conclude that conservative management of staghorn calculi is not as unsafe as previously thought. Careful patient selection to include unilateral asymptomatic stones with minimal infection, and thorough counselling with regard to the risks, could make conservative management a suitable option for specific patient groups. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

Although many studies about penile prosthesis implantation (PPI) have been published so far, only a small amount of them take into account patients and partners outcome in terms of satisfaction and erotic function. The aim of this study is to explore the value of psycosexual counselling in and the sexual and erotic function of penile prosthesis recipients. Thirty patients and their partners were randomised into two groups. In arm A (case group) patients and their partners underwent a multistep psychosexual counselling before and after surgery. In arm B (control group) surgery was performed without the specific psychosexual counselling scheme. Specific questionnaires (International Index of Erectile Function (IIEF) and the Sexual Daydreaming Scale (SDS)) were administered before surgery and 12 months afterwards. Twenty-four months postoperatively patients were asked to complete the Global Assessment Questions (GAQ) and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), while their partners were asked to answer to the EDITS partner's section. Between January 2009 and October 2011, we enrolled 30 patients undergoing PPI in our institution (15 in each arm). Twenty-four months postoperative follow-up is available for all of them. No significant differences between the two groups in terms of baseline questionnaires scores were observed. Mean IIEF score was significantly higher in case group (arm A 68.3, arm B 53.4, P-value<0.001). At 12 months after PPI the improvement of erotic function according to SDS was significantly higher in the study group for both patients and their partners. Improvement in satisfaction rates were confirmed at 24 months, with statistically significant scores for EDITS in arm A patients and partners as compared with arm B. PPI with a pre- and postoperative psychosexual counselling scheme resulted in better postoperative sexual activity and erotic function for both patients and partners than PPI alone.

PURPOSE We studied the efficacy of osteopathic manual treatment (OMT) and ultrasound therapy (UST) for chronic low back pain. METHODS A randomized, double-blind, sham-controlled, 2 × 2 factorial design was used to study OMT and UST for short-term relief of nonspecific chronic low back pain. The 455 patients were randomized to OMT (n = 230) or sham OMT (n = 225) main effects groups, and to UST (n = 233) or sham UST (n = 222) main effects groups. Six treatment sessions were provided over 8 weeks. Intention-to-treat analysis was performed to measure moderate and substantial improvements in low back pain at week 12 (30% or greater and 50% or greater pain reductions from baseline, respectively). Five secondary outcomes, safety, and treatment adherence were also assessed. RESULTS There was no statistical interaction between OMT and UST. Patients receiving OMT were more likely than patients receiving sham OMT to achieve moderate (response ratio [RR] = 1.38; 95% CI, 1.16-1.64; P <.001) and substantial (RR = 1.41, 95% CI, 1.13-1.76; P = .002) improvements in low back pain at week 12. These improvements met the Cochrane Back Review Group criterion for a medium effect size. Back-specific functioning, general health, work disability specific to low back pain, safety outcomes, and treatment adherence did not differ between patients receiving OMT and sham OMT. Nevertheless, patients in the OMT group were more likely to be very satisfied with their back care throughout the study (P <.001). Patients receiving OMT used prescription drugs for low back pain less frequently during the 12 weeks than did patients in the sham OMT group (use ratio = 0.66, 95% CI, 0.43-1.00; P = .048). Ultrasound therapy was not efficacious. CONCLUSIONS The OMT regimen met or exceeded the Cochrane Back Review Group criterion for a medium effect size in relieving chronic low back pain. It was safe, parsimonious, and well accepted by patients. PMID:23508598

Inflammatory Bowel Disease (IBD) patients are at an increased risk of developing herpes zoster (HZ), especially when immunosuppressed. HZ may be preventable with the herpes zoster vaccine (HZV), but many patients are not offered vaccination over concern regarding efficacy and fear of adverse events. Although the Center for Disease Control and Prevention recommends that low-dose immunosuppression is not a contraindication, few IBD patients on these medications are receiving HZV. This study was a prospective clinical trial to assess the safety and immunogenicity of HZV among 2 groups of IBD patients. Group A consisted of 14 patients on low-dose immunomodulators and group B consisted of 25 patients either on 5-aminosalicylic acid or no IBD therapy. Blood samples were obtained to measure immune responses. HZ specific immunoglobulin G rose significantly in both groups but the response was lower in the immunosuppressed group (P = 0.0002). Peripheral blood mononuclear cell secretion of Tumor necrosis factor-α in response to HZ antigen increased after HZV in group B, but not in group A. Interleukin-8 secretion increased in both groups, but the response was much higher in group B. There were no significant differences in adverse events between groups. No patients developed a HZ-like rash within 1 year after vaccination. IBD patients on low-dose immunosuppressive therapy have a blunted immune response to HZV as compared with nonimmunosuppressed subjects. Despite this, immunosuppressed IBD patients are able to mount a statistically significant immune response. There were no serious adverse events to HZV.

It is not clear whether vitamin D should be actively supplemented in elderly patients suffering from an acute attack of COPD (AECOPD) and coronary heart disease (CHD). The patients were divided into three groups according to specific criteria: patients with AECOPD (group A), patients with COPD combined with CHD (group B), and patients with CHD (group C). We measured the levels of vitamin D and analyzed the correlation between vitamin D and important electrolytes, including prealbumin, creatinine, hemoglobin, cystatin C, blood fat, blood calcium, and blood magnesium, and the nutrition state of the whole body. The serum B-type natriuretic peptide (BNP) was measured using an ELISA kit. The vitamin D level in group B was the lowest, followed by group A. When compared with group C, they all had statistical significance (P<0.05), but there was no statistical difference between groups A and B. There was no difference among the three groups when prealbumin, creatinine, hemoglobin, cystatin C, blood fat, blood calcium, and blood magnesium were compared. The level of BNP in the three groups increased, but it had no obvious correlation with the level of vitamin D (P>0.05). When elderly patients have coronary artery disease with AECOPD, vitamin D levels were obviously lower and were negatively correlated with the BNP. Low vitamin D levels, as well as poor nutrition, affect cardiopulmonary function and quality of living of elderly patients, especially female patients. Therefore, vitamin D should be supplemented more actively in the female patients suffering from AECOPD and CHD.

Neuropeptide Y (NPY) is one of the most potent endogenous vasoconstrictors, and its contribution to the multifactorial cascade of cerebral vasospasm due to nontraumatic subarachnoid hemorrhage (SAH) is not yet fully understood. This experimental study compared the hemorrhage-specific course of NPY secretion into cerebrospinal fluid (CSF) and into plasma between 2 groups: patients with SAH and patients with basal ganglia hemorrhage (BGH) or cerebellar hemorrhage (CH) over the first 10 days after hemorrhage. Seventy-nine patients were prospectively included: SAH patients (n=66) (historic population) and intracerebral hemorrhage patients (n=13). All patients received an external ventricular drain within 24 hours of the onset of bleeding. CSF and plasma were drawn daily from day 1 to day 10. The levels of NPY were determined by means of competitive enzyme immunoassay. The CSF samples of 29 patients (historic population) who had undergone spinal anesthesia due to orthopedic surgery served as the control group. NPY levels in CSF were significantly higher in the 2 hemorrhage groups than in the control group. However, the 2 hemorrhage groups showed significant differences in NPY levels in CSF (SAH mean, 0.842 ng/mL vs. BGH/CH mean, 0.250 ng/mL; P<0.001) as well as in the course of NPY secretion into CSF over the 10-day period. NPY levels in plasma did not differ significantly among SAH, BGH/CH, and controls. Our findings support the hypothesis that excessive release of NPY into CSF but not into plasma is specific to aneurysmal SAH in the acute period of 10 days after hemorrhage. In BGH/CH, CSF levels of NPY were also increased, but the range was much lower.

In the present study, we showed that a representational disorder for words can dissociate from both representational neglect for objects and neglect dyslexia. This study involved 14 brain-damaged patients with left unilateral spatial neglect and a group of normal subjects. Patients were divided into four groups based on presence of left neglect dyslexia and representational neglect for non-verbal material, as evaluated by the Clock Drawing test. The patients were presented with bisection tasks for words and lines. The word bisection tasks (with words of five and seven letters) comprised the following: (1) representational bisection: the experimenter pronounced a word and then asked the patient to name the letter in the middle position; (2) visual bisection: same as (1) with stimuli presented visually; and (3) motor bisection: the patient was asked to cross out the letter in the middle position. The standard line bisection task was presented using lines of different length. Consistent with the literature, long lines were bisected to the right and short lines, rendered comparable in length to the words of the word bisection test, deviated to the left (crossover effect). Both patients and controls showed the same leftward bias on words in the visual and motor bisection conditions. A significant difference emerged between the groups only in the case of the representational bisection task, whereas the group exhibiting neglect dyslexia associated with representational neglect for objects showed a significant rightward bias, while the other three patient groups and the controls showed a leftward bisection bias. Neither the presence of neglect alone nor the presence of visual neglect dyslexia was sufficient to produce a specific disorder in mental imagery. These results demonstrate a specific representational neglect for words independent of both representational neglect and neglect dyslexia. ©2011 The British Psychological Society.

To determine whether there is a difference in shoulder-related physical function and quality of life between postoperative rehabilitation patients receiving standard care and those receiving care according to the American Society of Shoulder and Elbow Therapists' rehabilitation guideline for arthroscopic anterior capsulolabral repair of the shoulder. Descriptive studies with comparison between a retrospective and a prospective cohort. Municipal outpatient rehabilitation centre. A total of 96 arthroscopic Bankart-operated patients. A total of 52 patients received standard care; 44 patients underwent rehabilitation according to the American Society of Shoulder and Elbow Therapists' rehabilitation guideline. Primary outcome variable was Western Ontario Shoulder Instability Index. Secondary outcome measures were Patient-Specific Functional Scale, shoulder range of motion, return to work, return to sports, and costs. There was no significant difference in adjusted mean change scores between the standard care group and the guideline group in the primary outcome variable (Western Ontario Shoulder Instability Index total = 574.85 vs. 644.48) or the secondary outcomes (Patient-Specific Functional Scale = 4.6 vs. 5.0; range of motion in forward flexion = 46.49° vs. 49.58°; external rotation in adduction = 28.58° vs. 34.18°; external rotation in abduction = 51.29° vs. 47.55°; weeks until return to work = 5.2 vs. 6.9; weeks until return to sports =13.9 vs. 13.1; costs = number of visits; 18.5 vs. 15.9). There were no significant between-group differences in shoulder-related physical function and quality of life between the standard care group and the guideline group, following Bankart operations. © The Author(s) 2014.

In the field of psychosomatic medicine the relationship between personality characteristics and diseases is supposed to be an important issue. The aim of this article is to present group's MMPI profiles obtained for patients with different chronic diseases and to discuss about possible specific features of these different groups. We summarized results obtained by psychological testing of following groups of patients: adult patients treated with chronic maintenance dialysis, patients with diabetic retinopathy, general anxiety group, attack panic syndrome, parents of children with rheumatoid arthritis, as well as adolescents with mental anorexia, cystic fibrosis, diabetes mellitus and leukemia. Two control groups comprised adults and adolescents, both without any health problems, selected randomly. As a psychometric test MMPI-201 was used. Statistic 10 package is used for statistical analysis. In our presentation it can be seen some typical personality characteristics for patients with chronic conditions. These findings could be helpful for clinicians concerning treatment planning and follow-up. In general, the MMPI helps us to obtain a global, factual picture from the self-assessment of the patient, explained in a psycho-technical language. Group's profile could be used in clinical practice for planning treatment and to suppose the prognosis of the illness.

Back pain is a challenge for case management but is a health insurance fund (HIF) that identifies high risk patients and includes them in a back pain assessment and a multimodal program cost-effective? Case managers of a HIF contacted selected patients and requested information on pain and current perspectives. Patients in the intervention group were offered a multimodal assessment and, if applicable, a multimodal treatment program. Control group patients received verbal or written (back book) information. Cost data were evaluated with respect to the interview data 1 year prior and 1 year afterwards. Of the 800 insured persons contacted 621 were nationwide, 88 were regional controls and 91 were intervention patients. Inability to work was still rising in all groups but less in the intervention group versus both control groups. Drugs, hospital as well as cure/adjuvant costs were less for intervention patients than in both control groups. The investment for the program was thus more than refinanced. Case management was well accepted but the intervention was in need of training for case managers and the specific diagnostic and treatment option regionally. The HIF was responsible for the study investment and project partners shared the training of the HIF regional case managers.

To examine the impact of healthcare professional versus patient goal setting for the self-management of intermittent allergic rhinitis (AR) on symptom severity and quality of life. This was a 6 week, parallel group study. Group A participants, with pharmacist facilitation, nominated personally relevant goals and strategies relating to their AR. Group B participants had their goals and strategies set by the pharmacist. The main outcome measures used included perceived symptom severity and quality of life. In addition, goals and strategies data from participants of both groups were collected and analysed. Both groups demonstrated significant improvements in symptom severity and quality of life scores however Group B symptom severity scores improved more. Group B set a greater number of goals and strategies which were better structured and more task specific. This is the first study to investigate the impact of goal setting on patient behaviour in a chronic yet episodic illness. Our results suggest that self-management goals set by the healthcare professional which are clinically indicated but tailored to the patient's nominated symptoms yields better outcomes than goals nominated by the patient. A brief, structured intervention, tailored to patient symptoms, can enhance self-management of intermittent allergic rhinitis.

Task-specific focal hand dystonia can disable affected individuals. Although neurorehabilitation techniques such as sensory motor retuning can result in complete recovery in some patients, it requires many months of treatment. Combining transcranial direct current stimulation (tDCS) with neurorehabilitation is a new and promising approach that can help these patients. However, the results in different studies are contradictory. Analyze whether delivering tDCS (cathode over left and anode over right parietal region) during the neurorehabilitation process for musicians with dystonia can increase the effectiveness of therapy. A parallel double-blind randomized design was used to study 30 musicians with right-hand primary focal dystonia. All patients underwent a 2-week course of neurorehabilitation based on sensory motor retuning therapy coupled with either real or sham tDCS for the first 30 minutes of each daily 1-hour therapy session (total 10 sessions). The therapist and patient were blind to the tDCS condition. A dystonia severity score was obtained before and after the 2-week protocol. The therapist also rated the evolution of each patient. Both groups significantly improved their dystonia severity score during the 2 weeks. Score differences were 88.23 (±40.51) and 63.36 (±30.57) for the active and sham groups, respectively. The active group showed a statistically significant greater improvement. Biparietal tDCS with left-sided cathode is a safe technique that does not interfere with the neurorehabilitation procedure and can increase therapy effectiveness in rehabilitation patients with right-hand task-specific focal dystonia.

To investigate the effect of combining pain education, specific exercises and graded physical activity training (exercise) compared with pain education alone (control) on physical health-related quality of life (HR-QoL) in chronic neck pain patients. A multicentre randomised controlled trial of 200 neck pain patients receiving pain education. The exercise group received additional exercises for neck/shoulder, balance and oculomotor function, plus graded physical activity training. Patient-reported outcome measures (Short Form-36 Physical and Mental component summary scores, EuroQol-5D, Beck Depression Inventory-II, Neck Disability Index, Pain Bothersomeness, Patient-Specific Functioning Scale, Tampa Scale of Kinesiophobia, Global Perceived Effect) and clinical tests (Aastrand Physical Fitness, cervical Range of Motion, Pressure Pain Threshold at infraspinatus, tibialis anterior and cervical spine, Cranio-cervical Flexion, Cervical Extension muscle function, and oculomotion) were recorded at baseline and after 4 months. The exercise group showed statistically significant improvement in physical HR-QoL, mental HR-QoL, depression, cervical pressure pain threshold, cervical extension movement, muscle function, and oculomotion. Per protocol analyses confirmed these results with additional significant improvements in the exercise group compared with controls. This multimodal intervention may be an effective intervention for chronic neck pain patients.

The increased use of oral chemotherapy for the treatment of cancer introduces new challenges for patients and caregivers. Among them are the ability to swallow oral solid dosage forms, the proper administration of the agents and the safe-handling of chemotherapeutic drugs in the home. Since these drugs are hazardous, proper preparation, administration, and disposition introduces a variety of safety issues. The increased toxicity of these drugs coupled with complicated dosing regimens and the occasional need to dilute the drug or measure a liquid dosage form require careful instruction of the patient and/or caregivers. The purpose of this project was to create templates for writing patient instruction brochures. A group of clinicians specializing in oncology from several institutions in the United States and Canada met through a series of conference calls. The group included pharmacists with a specialty in pediatric oncology, investigational drug pharmacists, and an oncology nurse practitioner. National guidelines and practices at each institution were used for the creation of templates to be used in developing templates for medication and formulation-specific instruction brochures. The group developed six templates. The templates ranged in scope from instructions on the administration of intact tablets or capsules to directions on opening capsules or crushing tablets and mixing the content with foods or liquids. Thirty-three drug-specific brochures were developed using the templates. Templates of patient brochures and drug-specific brochures on the safe handling of chemotherapy in the home can be created using a collaborative, multi-institutional approach.

The aim of this study was to evaluate the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer Breast-Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). A total of 153 patients with breast cancer and 153 normal subjects completed three questionnaires of the Korean version of the EORTC QLQ-BR23. Multitrait scaling analyses demonstrated that all scales met multidimensional conceptualization criteria in terms of convergence and discrimination validity. Cronbach's alpha coefficients for five multiple-item scales were greater than 0.70 (range, 0.72-0.91). In known-group comparisons, there were marked group differences between patients differing in disease stage. In breast cancer patients, performance on the questionnaires was in the expected direction for almost all functioning and symptom scores. In addition, comparison between the patient and control groups showed that almost all variables discriminated between patients and normal individuals. In conclusion, the Korean version of the EORTC QLQ-BR23 was found to be a reliable and valid measure of quality of life in breast cancer patients, indicating that it should be used in clinical and epidemiological cancer research.

The purpose of this study was to assess leg muscle quality and give a detailed description of leg muscle involvement in a series of Duchenne muscular dystrophy patients using quantitative MRI and strength measurements. Fatty infiltration, as well as total and contractile (not fatty infiltrated) cross sectional areas of various leg muscles were determined in 16 Duchenne patients and 11 controls (aged 8-15). To determine specific muscle strength, four leg muscle groups (quadriceps femoris, hamstrings, anterior tibialis and triceps surae) were measured and related to the amount of contractile tissue. In patients, the quadriceps femoris showed decreased total and contractile cross sectional area, attributable to muscle atrophy. The total, but not the contractile, cross sectional area of the triceps surae was increased in patients, corresponding to hypertrophy. Specific strength decreased in all four muscle groups of Duchenne patients, indicating reduced muscle quality. This suggests that muscle hypertrophy and fatty infiltration are two distinct pathological processes, differing between muscle groups. Additionally, the quality of remaining muscle fibers is severely reduced in the legs of Duchenne patients. The combination of quantitative MRI and quantitative muscle testing could be a valuable outcome parameter in longitudinal studies and in the follow-up of therapeutic effects.

Objective The psychological processes of doubting and skepticism have recently become topics of neuroscientific investigation. In this context, we developed the False Tagging Theory, a neurobiological model of the belief and doubt process, which proposes that the prefrontal cortex is critical for normative doubt regarding properly comprehended cognitive representations. Here, we put our theory to an empirical test, hypothesizing that patients with prefrontal cortex damage would have a doubt deficit that would manifest as higher authoritarianism and religious fundamentalism. Method Ten patients with bilateral damage to the ventromedial prefrontal cortex (vmPFC), ten patients with damage to areas outside the vmPFC, and sixteen medical comparison patients, who experienced life-threatening (but non-neurological) medical events, completed a series of scales measuring authoritarianism, religious fundamentalism, and specific religious beliefs. Results VMPFC patients reported significantly higher authoritarianism and religious fundamentalism than the other groups. The degrees of authoritarianism and religious fundamentalism in the vmPFC group were significantly higher than normative values, as well; by contrast, the comparison groups did not differ from normative values. Moreover, vmPFC patients reported increased specific religious beliefs after brain injury. Conclusions The findings support the False Tagging Theory, and suggest that the vmPFC is critical for psychological doubt and resistance to authoritarian persuasion. PMID:22612576

Quality function deployment (QFD) is one of the most effective quality design tools. This study applies QFD technique to improve the quality of the burn unit services in Ghotbedin Hospital in Shiraz, Iran. First, the patients' expectations of burn unit services and their priorities were determined through Delphi method. Thereafter, burn unit service specifications were determined through Delphi method. Further, the relationships between the patients' expectations and service specifications and also the relationships between service specifications were determined through an expert group's opinion. Last, the final importance scores of service specifications were calculated through simple additive weighting method. The findings show that burn unit patients have 40 expectations in six different areas. These expectations are in 16 priority levels. Burn units also have 45 service specifications in six different areas. There are four-level relationships between the patients' expectations and service specifications and four-level relationships between service specifications. The most important burn unit service specifications have been identified in this study. The QFD model developed in the study can be a general guideline for QFD planners and executives.

Background Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Methodology/Principal Findings Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Conclusions/Significance Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF. PMID:26849126

The purposes of this study were to create a new flow-chart of prehospital electrocardiography (ECG)-transmission, evaluate its predictive ability for ST-elevation myocardial infarction (STEMI) and shorten door-to-balloon time (DTBT). The new transmission flow-chart was created using symptoms from previous medical records of STEMI patients. A total of 4090 consecutive patients transferred emergently to our hospital were divided into two groups: those in ambulances with an ECG-transmission device with the new flow-chart (ECGT-FC) and those transferred without an ECG-transmission device (non-ECGT) groups. A STEMI group comprising walk-in patients during the same period was used as a control group. The predictive ability of STEMI and the effectiveness of shortening the DTBT by the new flow-chart of ECG-transmission was evaluated. In the ECGT-FC group, the prevalence of STEMI in the ECG-transmission by the new flow-chart were significantly higher than in the non-ECG-transmission patients (6.71% vs. 0.19%; p<0.001). The sensitivity and specificity of the new ECG-transmission flow-chart were 83.3% and 88.1%, respectively. The median DTBT was significantly shortened (p=0.045) and the prevalence of DTBT<90min was significantly higher in the ECGT-FC group (p=0.018) than the other groups. The sensitivity and specificity of the new flow-chart for ECG-transmission were high. The new flow-chart combined with an ECG-transmission device could detect STEMI efficiently and shorten DTBT.

Clozapine-associated fever is common but the specific cytokine changes and treatment durations that may cause fever remain unknown. We investigated the association between inflammatory cytokine changes and clozapine-induced fever in patients who were treated with clozapine. Forty-three patients with schizophrenia or schizoaffective disorder, diagnosed by using the Chinese Version of the Mini International Neuropsychiatric Interview, were treated with clozapine for the first time (first-time use group, n = 22) or for more than 6 months (long-term use group, n = 21). The Positive and Negative Syndrome Scale, tympanic temperature, and levels of tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ), interleukin-2 (IL-2), and interleukin-6 (IL-6) were determined at baseline and weeks 1, 2, 3, 4, and 6. A multiple linear regression with generalized estimating equation methods was used to analyze the association between the changes in the cytokine levels and clozapine-induced fever in the different groups. The IL-6 level changes were significantly different between the two groups (P = 0.04). In the first-time use group, the fever rate was increased (47.1%) compared with the long-term use group (5.6%, P = 0.005). Moreover, in these patients, the TNF-α, INF-γ, IL-2, and IL-6 levels were significantly (P < 0.001) different from patients who did not develop a fever. An interaction effect with the different treatment duration groups and fever development was only significant for IL-6 (P < 0.001). Patients who were treated with clozapine for the first time have an increased rate of developing a fever, and IL-6 might have a specific role in the interaction effect between treatment duration and fever development. © 2017 The Authors.

Introduction. The impact of preoperative BMI on surgical outcomes and long-term survival of gastric cancer patients was investigated in various reports with contrasting results. Materials & Methods. A total of 378 patients who underwent a surgical resection for primary gastric cancer between 1994 and 2011 were retrospectively studied. Patients were stratified according to BMI into a normal group (<25, group A), an overweight group (25–30, group B), and an obesity group (≥30, group C). These 3 groups were compared according to clinical-pathological characteristics, surgical treatment, and long-term survival. Results. No significant correlations between BMI and TNM (2010), UICC stage (2010), Lauren's histological type, surgical results, lymph node dissection, and postoperative morbidity and mortality were observed. Factors related to higher BMI were male gender (P < 0.05), diabetes (P < 0.001), and serum blood proteins (P < 0.01). A trend to fewer lymph nodes retrieved during gastrectomy with lymphadenectomy in overweight patients (B and C groups) was observed, although not statistically significant. There was no difference in overall survival or disease-specific survival between the three groups. Conclusion. According to our data, BMI should not be considered a significant predictor of postoperative complications or long-term result in gastric cancer patients. PMID:25759721

Epithelial ovarian cancer (EOC) is the most lethal gynecological cancer. Several approaches of active and passive immunotherapy for EOC have been studied. The aim of this systematic review was to assess the clinical efficacy of specific immunotherapy in patients with EOC. We found 4524 references in seven databases and we included ten controlled clinical trials with 2285 patients with EOC reporting five active immunotherapeutic agents and three passive immunotherapies. Meta-analysis of six studies showed that overall there was not any significant difference in overall survival and recurrence-free survival between patients undergoing specific immunotherapy and those in control group. Most of the studies we evaluated reported a positive outcome from treatment with specific immunotherapy, although this was not significant.

This study aims to discuss the influence of different types of transformation zone (TZ) on positive surgical margin of loop electrosurgical excision procedure (LEEP) and the significance of infection of different genetic high-risk HPV for cervical intraepithelial neoplasm. The clinical data of patients who had CIN2+ and received LEEP during January to December 2013 was investigated. The conditions of positive surgical margin of patients of different transformation zone (type I, II, III) were analyzed. The clinical high-risk types of HPV were divided into three groups, including A5/6, A7 and A9, compared with the pathological conditions of pre-operation and post-operation of the patients in respective group. The results indicated that type III transformation zone is more likely to cause positive cutting margin. For CIN2+ patients, sensitivity and specificity are 0.89% and 79.56% in group A5/6, and negative and positive predicted value (NPV, PPV) are 40% and 5%. The sensitivity, specificity, NPV, PPV in group A7 is 12.5%, 44.08%, 29.49% and 21.21%, respectively. The sensitivity, specificity, NPV, PPV in group A9 is 88.99%, 87.09%, 85.26%, 81.51%, respectively. Transformation zone type was correlated positively with positive cutting margin percentage (r = 0.8732, P < 0.05). Compared with type I, type II and III transformation zone is more likely to cause pathological upgrades. In conclusion, different types of transformation zone and high-risk HPV have clinical significance in causing positive cutting margin of surgery and disease extent.

Abstract It is not well established whether the incident outcomes of the clinical high-risk (CHR) syndrome for psychosis are diagnostically specific for psychosis or whether CHR patients also are at elevated risk for a variety of nonpsychotic disorders. We collected 2 samples (NAPLS-1, PREDICT) that contained CHR patients and a control group who responded to CHR recruitment efforts but did not meet CHR criteria on interview (help-seeking comparison patients [HSC]). Incident diagnostic outcomes were defined as the occurrence of a SIPS-defined psychosis or a structured interview diagnosis from 1 of 3 nonpsychotic Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) groups (anxiety, bipolar, or nonbipolar mood disorder), when no diagnosis in that group was present at baseline. Logistic regression revealed that the CHR vs HSC effect did not vary significantly across study for any emergent diagnostic outcome; data from the 2 studies were therefore combined. CHR (n = 271) vs HSC (n = 171) emergent outcomes were: psychosis 19.6% vs 1.8%, bipolar disorders 1.1% vs 1.2%, nonbipolar mood disorders 4.4% vs 5.3%, and anxiety disorders 5.2% vs 5.3%. The main effect of CHR vs HSC was statistically significant (OR = 13.8, 95% CI 4.2–45.0, df = 1, P < .001) for emergent psychosis but not for any emergent nonpsychotic disorder. Sensitivity analyses confirmed these findings. Within the CHR group emergent psychosis was significantly more likely than each nonpsychotic DSM-IV emergent disorder, and within the HSC group emergent psychosis was significantly less likely than most emergent nonpsychotic disorders. The CHR syndrome is specific as a marker for research on predictors and mechanisms of developing psychosis. PMID:26272875

To determine the validity of the proposed clinical diagnostic criteria for anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis in paediatric patients. The diagnostic criteria for anti-NMDAR encephalitis proposed by Graus et al. (2016) use clinical features and conventional investigations to facilitate early immunotherapy before antibody status is available. The criteria are satisfied if patients develop four out of six symptom groups within 3 months, together with at least one abnormal investigation (electroencephalography/cerebrospinal fluid) and reasonable exclusion of other disorders. We evaluated the validity of the criteria using a retrospective cohort of paediatric patients with encephalitis. Twenty-nine patients with anti-NMDAR encephalitis and 74 comparison children with encephalitis were included. As expected, the percentage of patients with anti-NMDAR encephalitis who fulfilled the clinical criteria increased over time. During the hospital inpatient admission, most patients (26/29, 90%) with anti-NMDAR encephalitis fulfilled the criteria, significantly more than the comparison group (3/74, 4%) (p<0.001). The median time of fulfilling the criteria in patients with anti-NMDAR encephalitis was 2 weeks from first symptom onset (range 1-6). The sensitivity of the criteria was 90% (95% confidence interval 73-98) and the specificity was 96% (95% confidence interval 89-99). The proposed diagnostic criteria for anti-NMDAR encephalitis have good sensitivity and specificity. Incomplete criteria do not exclude the diagnosis. The proposed clinical diagnostic criteria for anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis by Graus et al. (2016) have high sensitivity and specificity in paediatric patients. The median time of fulfilling the criteria in patients with anti-NMDAR was 2 weeks from first symptom onset. © 2017 Mac Keith Press.

To develop a specific rehabilitation protocol for patients who have undergone surgical repair of acute aneurysmal subarachnoid hemorrhage (aSAH), and to determine the time at which verticalization should be initiated after aSAH. Sixty-five patients who underwent acute-term surgery for aSAH and early rehabilitation were evaluated in groups: Group 1 (n=34) started verticalization on days 2-5 post-bleeding whereas Group 2 (n=31) started verticalization approximately day 12 post-bleeding. All patients were monitored for early complications, vasospasm and ischemia. Assessments of motor status, depression and anxiety (using Zung scales), and cognitive status (using the Mini-Mental State Examination (MMSE)) were conducted at discharge and at 1 and 3 months post-surgery. At discharge, Group 1 had a significantly higher proportion of patients with ischemia than Group 2 (p=0.004). Group 1 had a higher proportion of patients with hemiparesis than Group 2 three months post-surgery (p=0.015). Group 1 patients scored significantly higher on the Zung depression scale than Group 2 patients at 1 month (p=0.005) and 3 months post-surgery (p=0.001; the same applies to the Zung anxiety scale (p=0.006 and p=0.000, respectively). Group 2 patients scored significantly higher on the MMSE than those in Group 1 at discharge (p=0.040) and 1 month post-surgery (p=0.025). Early verticalization had no effect with respect to preventing early postoperative complications in this patient group. Once a patient has undergone acute surgical repair of aSAH, it is safe and preferred that rehabilitation be initiated immediately postsurgery. However, verticalization should not start prior to day 12 post-bleeding.

To assess the effectiveness of 12 weeks of Pilates practice on disability, pain and kinesiophobia in patients with chronic non-specific low back pain. This is a randomized controlled trial. This study was conducted in the university laboratory. A total of 64 participants with chronic non-specific low back pain were included. Participants were randomly allocated to intervention group consisted in Pilates intervention during 12 weeks ( n = 32) or control group who received no treatment ( n = 32). Disability, pain and kinesiophobia were assessed by Roland Morris Disability Questionnaire, visual analogue scale and Tampa Scale of Kinesiophobia, respectively. Measurements were performed at baseline, at 6 and 12 weeks after study completion. There were significant differences between groups with observed improvement in Pilates intervention group in all variables after treatment ( P < 0.001). Major changes on disability and kinesiophobia were observed at six weeks of intervention with no significant difference after 12 weeks ( P < 0.001). Mean changes of the intervention group compared with the control group were 4.00 (0.45) on the Roland Morris Disability Questionnaire and 5.50 (0.67) in the Tampa Scale of Kinesiophobia. Pain showed better results at six weeks with a slightly but statistically significant improvement at 12 weeks with Visual Analogue Scale scores of 2.40 (0.26) ( P < 0.001). Pilates intervention in patients with chronic non-specific low back pain is effective in the management of disability, pain and kinesiophobia.

Role of autobiographical memory in social problem solving and depression.

Depressed patients frequently exhibit deficiencies in social problem solving (SPS). A possible cause of this deficit is an impairment in patients' ability to retrieve specific autobiographical memories. A clinically depressed group and a hospital control group performed the Means-End Problem-Solving (MEPS; J. J. Platt & G. Spivack, 1975a) task, during which they were required to attend to the memories retrieved during solution generation. Memories were categorized according to whether they were specific, categoric, or extended and whether the valence of the memories was positive or negative. Results support the general hypothesis that SPS skill is a function of autobiographical memory retrieval as measured by a cuing task and by the types of memories retrieved during the MEPS. However, the dysfunctional nature of categoric memories in SPS, rather than the importance of specific memories, was highlighted in the depressed group. Valence proved to be an unimportant variable in SPS ability. The cyclical links among autobiographical memory retrieval, SPS skills, and depression are discussed.

Sensory-motor returning (SMR) can help the symptoms of task-specific focal hand dystonia. However, effects vary across patients and take many sessions. Here, we present proof of principle evidence that transcranial direct current stimulation (tDCS) can enhance these effects. We compared the effects of a combined tDCS-SMR protocol (n=4 patients) with the efficacy of SMR alone (n=30 patients). All 4 patients treated with the combined protocol showed greater improvement than those undergoing SMR alone. Results encourage a larger, parallel-group clinical trial with sham tDCS control.

Studies examining patient-reported outcomes in subjects with vestibular schwannoma (VS) and "excellent" hearing are lacking. To assess patient-reported audiovestibular handicap and overall quality of life (QoL) in VS patients with class A hearing in both ears. Among 539 VS patients treated during 1998 to 2008, we identified 296 patients with either bilateral class A (AA) hearing or 1 good ear and 1 deaf ear (AD) according to the American Academy of Otolaryngology-Head and Neck Surgery classification. Patients responded to validated hearing, tinnitus, and dizziness handicap inventories and 2 QoL questionnaires, and the 2 groups were compared. A reference group of 103 adults filled out the same questionnaires. Forty-nine patients (16.6%) had class AA and 247 patients (83.4%) had class AD hearing. AA patients scored poorer than control subjects without tumor on all handicap questionnaires ( P < .001) and a VS-specific QoL instrument ( P = .006). Con-versely, AA patients scored significantly better than patients with AD on the hearing inventory and the disease-specific QoL instrument ( P < .001), but no difference was found between these groups with regard to tinnitus and dizziness. The hearing disability score was approximately 3 times poorer for AA patients compared with control subjects without tumor; a third of AA patients reported a hearing handicap. Patients with VS and bilateral class A hearing report significantly poorer hearing handicap than control subjects without tumor but better hearing than those with unilateral deafness. When patients with bilateral class A hearing are counseled, it should be noted that one-third of patients experience self-perceived hearing handicap.
