This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compared preoperatively, as well as on the first postoperative day, 6th and 12th months postoperatively. Clinical assessment was performed using the ODI and the VAS of low back pain. The pre- and immediate postoperative segmental lordosis angles were 12.9° and 12.6° in the 4° group and 12° and 12.0° in the 8° group. Both groups exhibited no significant different segmental lordosis angle and total lumbar lordosis over period and time. However, the total lumbar lordosis significantly increased from six months postoperatively compared with the immediate postoperative day in the 8° group. The ODI and the VAS in both groups had no differences. Cages with different lordotic angles of 4° and 8° showed insignificant results clinically and radiologically in short-level PLIF surgery. Clinical improvements and sagittal alignment recovery were significantly observed in both groups. PMID:25685795

Abstract Background There is evidence for a group of nonclinical individuals with full-blown, persistent psychotic experiences (PEs) but no need-for-care: they are of particular importance in identifying risk and protective factors for clinical psychosis. The aim of this study was to investigate whether reasoning biases are related to PEs or need-for-care. Method Two groups with persistent PEs (clinical; n = 74; nonclinical; n = 92) and a control group without PEs (n = 83) were compared on jumping-to-conclusions (JTC) and belief flexibility. A randomly selected subset of interviews (n = 104) was analyzed to examine differences in experiential and rational reasoning. Results As predicted JTC was more common in the clinical than the other 2 groups. Unexpectedly no group differences were observed between clinical and nonclinical groups on measures of belief flexibility. However, the clinical group was less likely to employ rational reasoning, while the nonclinical group was more likely to use experiential reasoning plus a combination of both types of reasoning processes, compared to the other 2 groups. Conclusions Reasoning biases differ in groups with PEs with and without need-for-care. JTC is associated with need-for-care rather than with PEs. The ability to invoke rational reasoning processes, together with an absence of JTC, may protect against pathological outcomes of persistent PEs. However, marked use of experiential reasoning is associated with the occurrence of PEs in both clinical and nonclinical groups. Implications for theory development, intervention and further research are discussed. PMID:28338872

The oral lichenoid disease (OLD) includes different chronic inflammatory processes such as oral lichen planus (OLP) and oral lichenoid lesions (OLL), both entities with controversial diagnosis and malignant potential. Epidermal growth factor receptor (EFGR) is an important oral carcinogenesis biomarker and overexpressed in several oral potentially malignant disorders. Objectives: To analyze the EGFR expression in the OLD to find differences between OLP and OLL, and to correlate it with the main clinical and pathological features. Material and Methods: Forty-four OLD cases were studied and classified according to their clinical (Group C1: only papular lesions / Group C2: papular and other lesions) and histopathological features (Group HT: OLP-typical / Group HC: OLP-compatible) based in previous published criteria. Standard immunohistochemical identification of EGFR protein was performed. Comparative and descriptive statistical analyses were performed. Results: Thirty-five cases (79.5%) showed EGFR overexpression without significant differences between clinical and histopathological groups (p<0.05). Histological groups showed significant differences in the EGFR expression pattern (p=0.016). Conlusions: All OLD samples showed high EGFR expression. The type of clinical lesion was not related with EGFR expression; however, there are differences in the EGFR expression pattern between histological groups that may be related with a different biological profile and malignant risk. Key words:Oral lichenoid disease, oral lichen planus, oral lichenoid lesion, oral carcinogenesis, EGFR. PMID:24880441

Cognitive assessment is essential in tracking disease progression in AD. Presently, cohorts including preclinical at-risk participants are recruited by different means, which may bias cognitive and clinical features. We compared recruitment strategies to levels of cognitive functioning. We investigate recruitment source biases in self-referred and memory clinic-referred patient cohorts to reveal potential differences in cognitive performance and demographics among at-risk participants. We included 431 participants 40-80 years old. Participants were classified as controls (n = 132) or symptom group (n = 299). The symptom group comprised of subjective cognitive decline (SCD, n = 163) and mild cognitive impairment (MCI, n = 136). We compared cognitive performance and demographics in memory clinic-referrals (n = 86) to self-referred participants responding to advertisements and news bulletins (n = 179). Participants recruited by other means were excluded from analysis (n = 34). At symptom group level, we found significant reductions in cognitive performance in memory clinic-referrals compared to self-referrals. However, here reductions were only found within the MCI group. We found no differences in cognitive performance due to recruitment within the SCD group. The MCI group was significantly impaired compared to controls on all measures. Significant reductions in learning, and executive functions were also found for the SCD group. Regardless of recruitment method, both the SCD and MCI groups showed reductions in cognitive performance compared to controls. We found differences in cognitive impairment for memory clinic-referrals compared to self-referrals only within the MCI group, SCD-cases being equally affected irrespective of referral type.

OBJECTIVE To study the potential differences in patient characteristics between two referral methods to a fall clinic, specifically: case-finding of patients admitted to an emergency department because of a fall, compared to direct referral to the fall clinic via the general practitioner. Cross-sectional study. Fall clinics in two university teaching hospitals in the Netherlands. Three hundred community-dwelling older people aged 65 years or over currently attending the fall clinics in Nijmegen (Group 1, n=154) and in Amsterdam (Group 2, n=146). Patients were referred by a general practitioner (Group 1) or were selected using the Carefall Triage Instrument (CTI) after visiting the emergency department (Group 2). In all patients, modifiable risk factors for recurrent falls were assessed. Group 1 had less modifiable risk factors for falling (a mean of 4 (SD 1.6) vs. a mean of 5 (SD 1.5) in Group 2, p < 0.001). Compared to Group 2, Group 1 had more prevalent " recurrent falling (≥ 2 falls)" (p=0.001) and "assisted living in homes for the aged" (p=0.037). "Fear of falling", "mobility and balance problems", "home hazards" and "osteoporosis" were significantly less prevalent in Group 1. This study suggests that patients referred to a multidisciplinary fall prevention clinic by their general practitioner have a different risk profile than those selected by case finding using the CTI. These differences have consequences for the reach of secondary care for fall-preventive interventions and will probably influence the effectiveness and efficiency of a fall prevention program.

Clinical research and practice support a multi-method approach to validating behavioral problems in children. We examined whether parent-reported symptoms of hyperactivity and inattention (using the Disruptive Behavior Disorder Rating Scale) were substantiated by objective laboratory measures [hyperactivity measured by wrist-worn actigraphy (ACT) and inattention assessed using a 20-minute continuous performance task (CPT)] in three age- and demographically-matched groups of school-age children: children with prenatal alcohol exposure (AE), non-exposed children with idiopathic ADHD (ADHD), and controls (CON). Results indicated that the clinical groups (AE, ADHD) had significantly higher parent-reported levels for both domains compared to the CON group, and did not differ from each other. On the laboratory measures, the clinical groups were more inattentive than controls on the CPT, but did not differ from each other. In contrast, the ADHD group had higher objective activity on the ACT than AE and CON, which did not differ from each other. Thus, laboratory measures differentially validated parent reports in a group-dependent manner. Actigraphy substantiated parent-reported hyperactivity for children in the ADHD group but not for children in the AE group, while the CPT validated parent-reported inattention for both clinical groups. Although the majority of children in the AE group met criteria for ADHD, objective activity levels were not different from controls, indicating that hyperactivity may be a less prominent feature in the AE group. Thus, while there is considerable overlap between the effects of prenatal alcohol exposure and ADHD, differences in behavioral profiles may be clinically useful in differential diagnosis. Further, these data indicate that objective measures should be used to validate parent reports. PMID:24512965

The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

Orthorexia nervosa (ON) is defined as pathological healthful eating. The aim of this study was to investigate whether there is any difference in orthorexic behaviours between clinical and non-clinical groups, and in different cultural contexts. . Recruitment involved both female patients with anorexia nervosa (AN) and healthy controls (HC) from Italy and Poland (N = 23 and N = 35 AN patients; and N = 39 and N = 39 HCs, in Italy and Poland, respectively). Assessment of orthorexic behaviours was performed with the ORTO-15 test. Statistically significant differences were found between Italian women in the AN and HC group, whereas no difference between Polish women in the AN and HC group was found. Both Italian groups scored significantly higher than the Polish ones on the ORTO-15. Differences have been found between the Italian and Polish samples, both in the percentage of individuals with orthorexic behaviours as suggested by an ORTO 15 score below the cutoff, and in the mean ORTO 15 scores in the AN and HC groups, suggesting cross-cultural differences in orthorexic behaviours, whose meaning is currently difficult to understand.

This study aimed to examine the associations between family history and clinical manifestations and immunologic characteristics of lupus in China. Based on their family history, lupus patients from the Chinese lupus treatment and research group (CSTAR) registry were categorised: familial lupus (FL), family history of other rheumatic disorders (RD), and sporadic lupus (SL). Demographic data, clinical manifestations, and laboratory data were compared among these three groups. A total of 2,104 patients from CSTAR were included, with 34 (1.6%) in the FL group, 50 (2.4%) in the RD group, and 2,020 (96.0%) in the SL group. There were no significant differences in age or gender among these groups (p=0.36 and p=0.75, respectively). The prevalence of discoid rash and positivity of anti-RNP antibodies differed significantly among the three groups. Photosensitivity and neurological disorder were marginally significantly different among the three groups (p=0.05). No statistical differences were observed in other clinical manifestations or laboratory results. In the FL group, first-degree relatives (25/34, 73.5%) had higher susceptibility to lupus. Rheumatoid arthritis (RA) (35/50, 70.0%) was the most frequent non-lupus rheumatic disorder in the RD group. Among lupus patients, the rate of familial lupus was lower in Chinese patients than among other ethnicities. Familial lupus cases are found mainly among their first-degree relatives. A family history of lupus did not significantly affect clinical phenotypes, except for higher frequency of discoid rash and anti-RNP in the FL group, and more anti-RNP positivity in the RD group.

To investigate the clinical effect of double dose of valsartan combined with tacrolimus in the treatment of diabetic nephropathy (DN). HA total of 86 cases diagnosed with DN were selected from October 2013 to October 2014 in Zaozhuang Municipal Hospital, China. The study was approved by our hospital Ethics Committee and written consent was obtained from patients and their family members. Patients were randomly divided into three groups according to the sequence of admission, group A (conventional dose of valsartan group, n = 28 cases), group B (double dose of valsartan group, n = 29 cases) and group C (double dose of valsartan combined with tacrolimus group, n = 29). Clinical effects were compared by analyzing the renal function tests after 8 weeks. 24h urine protein, serum creatinine level of patients in group B and group C were significantly lower than that of group A. Those in group C was much lower. The glomerular filtration rates were significantly higher for group B and C than that of group A, and those in group C were much higher. The difference is statistically significant (p < 0.05). High-sensitivity C-reactive protein (hs CRP) and adiponectin levels of patients in group B and C of were significantly lower than that of group A and those in group C were much lower. The difference is statistically significant (p < 0.05). The high mobility group protein 1 (HMGB1) and renal tubular and interstitial damage index (TDI) of patients in B and C groups were significantly lower than those in the A group, and those in C group were significantly lower. The difference was statistically significant p < 0.05). The clinical effective rates of patients in group B and C were significantly higher than that in group A, and those of group C were much higher. The difference is statistically significant (p < 0.05). The recurrence rates of patients in group B and group C were significantly lower than those of group A and those in group C were much lower. The difference is statistically significant (p < 0.05). Patients in three groups showed no obvious drug complications. Double dose of valsartan combined with tacrolimus treatment of DN patients can improve clinical symptoms, reducing inflammation, inhibiting or even reversing the interstitial fibrosis, which will improve the curative effect and reduce the recurrence, as to provide a new theoretical basis for the clinical treatment of the disease.

The study was undertaken to correlate the blood groups and clinical presentations in malaria patients and to understand the differential host susceptibility in malaria. From October 2007 to September 2008, malaria positive patients' samples were evaluated in this study. Hemoglobin, total leukocyte count, and platelet count of each patient were done on an automated cell counter. After determining the blood groups, malarial species and the severity of clinical course were correlated. A total of 100 patients were included in the study, of which 63 cases were positive for Plasmodium falciparum and 37 cases were positive for P. vivax infection and 11 patients had mixed infection. The results of the blood groups showed 22 - 'A' group, 42 - 'B' group, 35 - 'O' group and 1 was 'AB' group. When the clinical courses between different groups were compared using the following parameters for severe infection--a parasitic load of >10/1000 RBCs, severe anemia with hemoglobin < 6 g%, platelet count of <10,000/mm3, hepato or splenomegaly or clinical signs of severe malaria such as fever >101°F and other organ involvement, it was observed that 'O' group had an advantage over other the groups. The difference in rosetting ability between red blood cells of different 'ABO' blood groups with a diminished rosetting potential in blood group 'O' red blood cells was due to the differential host susceptibility. 'O' group had an advantage over the other three blood groups. Based on literature and the results of this study, the diminished rosetting potential in blood group 'O' red blood cells is suggested as the basis for the differential host susceptibility.

The transition to full-time clinical studies holds anxieties for most medical students. While graduate entry medical education has only recently begun in the UK, the parallel undergraduate and graduate entry MBBS courses taught at our school allowed us to study how 2 differently prepared groups perceived this vital time at a comparable stage in their training. An anonymous questionnaire collected demographic data and graded anxiety in 13 statements relating to starting full-time clinical attachments. Two open questions allowed free text comment on the most positive and negative influences perceived during this time. Both a statistical analysis and a qualitative assessment were performed to compare the 2 groups of students. The 2 groups were similar with respect to gender but the graduate entry students were significantly older. The graduate entry students were significantly less anxious about most aspects of the transition period compared to the undergraduates. These course differences remained after adjusting for age and sex. When adjusted for course and age, male students expressed less anxiety. The main positive qualitative statements related to continual clinical and communication skills training in the graduate entry group. The main qualitative concerns in both groups related to 'fitting in' and perceived lack of factual knowledge. These data support the early introduction of clinical skills teaching, backed up by a fully integrated clinically relevant curriculum with continued assessment, in preparing students and reducing levels of anxiety before they start full-time clinical attachments. These course design differences appear to be more important than any differences in maturity between the 2 groups.

Measuring the level of serum lipase has been used for the clinical diagnosis of acute pancreatitis. Reports showed that the serum lipase level increased in patients of clinical renal failure. In this study, we aimed to measure the change of serum lipase levels in chronic kidney diseases and determine whether it could serve as a clinical laboratory index for clinical renal failure diagnosis. Materials: The OLYMPUS AU5400 automatic biochemical analyzer was used to determine the serum levels of lipase and creatinine. The study included 120 cases in the clinical renal failure group, 76 cases in the nephrotic syndrome group, 81 cases in the chronic nephritis group, and 80 healthy controls from our hospital volunteers in the same period. We then compared the lipase levels and conducted statistical analyses among these groups. The serum lipase levels were 15.3 U/L, 79.8 U/L, 45.1 U/L, and 51.0 U/L in the normal control, clinical renal failure, nephrotic syndrome, and chronic nephritis groups, respectively. The lipase levels in the groups with diseases were significantly different compared with that of the normal control group (p < 0.01). The lipase level of the clinical renal failure group was significantly higher than that of the nephrotic syndrome group and chronic nephritis group (p < 0.01). However, no statistically significant difference between the nephrotic syndrome and chronic nephritis group (p > 0.05) was observed. Moreover, an association of the serum lipase with disease progression was observed in the study. Serum lipase is an effective serological index which can reflect the clinical changes in the clinical renal failure and tends to increase through the progression of renal dysfunction.

Acetaminophen (APAP) is the most common cause of acute liver failure (ALF) in the west. It is unknown if APAP overdose in combination with diphenhydramine or opioids confers a different clinical presentation or prognosis. Study objectives were to compare (1) baseline patient characteristics; (2) initial clinical presentation; and (3) clinical outcomes among patients with ALF due to APAP alone or in combination with diphenhydramine or opioids. We analyzed 666 cases of APAP-related liver failure using the Acute Liver Failure Study Group database from 1998 to 2012. The database contains detailed demographic, laboratory, and clinical outcome data, including hemodialysis, transplantation, and death and in-hospital complications such as arrhythmia and infection. The final sample included 666 patients with APAP liver injury. A total 30.3% of patients were overdosed with APAP alone, 14.1% with APAP/diphenhydramine, and 56.6% with APAP/opioids. Patients taking APAP with opioids were older, had more comorbidities, and were more likely to have unintentional overdose (all P<0.0001). On presentation, 58% in the APAP/opioid group had advanced encephalopathy as compared with 43% with APAP alone (P=0.001) The APAP/diphenhydramine group presented with the highest serum aminotransferase levels, no differences in laboratory values were noted at 3 days postenrollment. No significant differences were observed in clinical outcomes among the groups. Most patients with APAP-induced ALF were taking APAP combination products. There were significant differences in patient characteristics and clinical presentation based on the type of product ingested, however, there were no differences noted in delayed hepatotoxicity or clinical outcomes.

Little is known about the use of biomarkers in guiding treatment decisions in routine asthma management. The objective of this study was to determine whether adding a LABA to an ICS would control bronchial hyperresponsiveness (BHR) at an overall lower dose of ICS when titration of medication was based upon the assessment of routine clinical measures with or without the measurement of BHR. After a 2-week run-in period, subjects (> or = 12 years) were randomized to one of three treatment groups. Two groups followed a BHR treatment strategy (based on clinical parameters [lung function, asthma symptoms, and bronchodilator use] and BHR) and were treated with either fluticasone propionate/salmeterol (FSC(BHR) group) or fluticasone propionate (FP(BHR) group) (n=156 each). The third group followed a clinical treatment algorithm (based on clinical parameters alone) and were treated with fluticasone propionate (FP(REF) group; n=154). All treatments were administered via Diskus. Treatment doses were adjusted as needed every 8 weeks for 40 weeks according to the subject's derived severity class, which was based on clinical measures of asthma control with or without BHR. The mean total daily inhaled corticosteroids (ICS) dose during the double-blind treatment period was lower, although not statistically significant, in the FSC(BHR) group compared with the FP(BHR) group (a difference of -42.9 mcg; p=0.07). Compared with the FP(REF) group, the mean total daily ICS dose was higher in the FSC(BHR) group (a difference of 85.2 mcg) and was significantly higher in the FP(BHR) group (a difference of 131.2 mcg, p=0.037). This study demonstrated that for most subjects, control of BHR was maintained when treatment was directed toward control of clinical parameters. In addition, there was a trend towards control of BHR and clinical measures at a lower dose of ICS when used concurrently with salmeterol.

This study's purpose was to compare the clinical and radiographic success rates of 5.25 percent Sodium Hypochlorite (NaOCl) pulpotomies to Formocresol (FC) and Ferric Sulfate (FS) in decayed primary molars. Eighty-one primary molars, randomly divided into three groups, were treated with one of three different pulpotomy materials; NaOCl, FC and FS. The outcomes of the different groups were assessed clinically and radiographically every six months over 18 months. Chi-square test was used to detect differences in outcome measures in all groups. At six months, clinical and radiographic success rates were 100 percent for each group (27/27). At 12 months, clinical success was 100 percent (24/24), 96 percent (24/25), and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. The radiographic success was 95.8 percent (23/24) for NaOCl group, and 100 percent for FC (25/25), and FS (23/23). At 18 months, the clinical success was 83.3 percent (20/24), 96 percent (24/25), and 87 percent (20/23) for NaOCL, FC, and FS respectively. The 18 month radiographic success was 91.7 percent (22/24), 100 percent (25/25), and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. No significant differences were found in clinical or radiographic outcomes between the three groups at six, 12 and 18 months. The three pulpotomy medicaments yielded similar outcomes.

The way people who experience mental illness are perceived by health care professionals, which often includes stigmatising attitudes, can have a significant impact on treatment outcomes and on their quality of life. To determine whether stigma towards people with mental illness varied for undergraduate nursing students who attended a non-traditional clinical placement called Recovery Camp compared to students who attended a 'typical' mental health clinical placement. Quasi-experimental. Seventy-nine third-year nursing students were surveyed; n=40 attended Recovery Camp (intervention), n=39 (comparison group) attended a 'typical' mental health clinical placement. All students completed the Social Distance Scale (SDS) pre- and post-placement and at three-month follow-up. Data analysis consisted of a one-way repeated measures analysis of variance (ANOVA) exploring parameter estimates between group scores across three time points. Two secondary repeated measures ANOVAs were performed to demonstrate the differences in SDS scores for each group across time. Pairwise comparisons demonstrated the differences between time intervals. A statistically significant difference in ratings of stigma between the intervention group and the comparison group existed. Parameter estimates revealed that stigma ratings for the intervention group were significantly reduced post-placement and remained consistently low at three-month follow-up. There was no significant difference in ratings of stigma for the comparison group over time. Students who attended Recovery Camp reported significant decreases in stigma towards people with a mental illness over time, compared to the typical placement group. Findings suggest that a therapeutic recreation based clinical placement was more successful in reducing stigma regarding mental illness in undergraduate nursing students compared to those who attended typical mental health clinical placements.

Patients diagnosed with anorexia nervosa (n = 30) and bulimia nervosa (n = 27), their parents and therapists were recruited for this study aimed at examining differences between clinical groups and a control group (n = 35) in terms of attachment styles and perceptions of memories of parental rearing. Within the clinical groups, relations among these variables and therapeutic bond were explored. In addition, parents' and their daughters' attachment styles were compared. The results showed differences between clinical and control groups: the daughters in the control group reported lower levels of attachment anxiety compared to those of the clinical groups; their mothers exhibited higher security than mothers of anorectic patients and lower avoidance than mothers of bulimic patients. For the anorectic group, therapeutic bond was associated to higher father's emotional support and lower rejection; in the bulimic group, therapeutic bond was related to higher maternal emotional support and lower rejection as well as to lower paternal overprotection.

Dental implant-retained overdentures have been chosen as the treatment of choice for complete mandibular removable dentures. Dental implants, such as mini dental implants, and components for retaining overdentures, are commercially available. However, comparative clinical studies comparing mini dental implants and conventional dental implants using different attachment for implant-retained overdentures have not been well documented. To compare the clinical outcomes of using two mini dental implants with Equator ® attachments, four mini dental implants with Equator attachments, or two conventional dental implants with ball attachments, by means of a randomized clinical trial. Sixty patients received implant-retained mandibular overdentures in the interforaminal region. The patients were divided into three groups. In Groups 1 and 2, two and four mini dental implants, respectively, were placed and immediately loaded by overdentures, using Equator ® attachments. In Group 3, conventional implants were placed. After osseointegration, the implants were loaded by overdentures, using ball attachments. The study distribution was randomized and double-blinded. Outcome measures included changes in radiological peri-implant bone level from surgery to 12 months postinsertion, prosthodontic complications and patient satisfaction. The cumulative survival rate in the three clinical groups after one year was 100%. There was no significant difference (p < 0.05) in clinical results regarding the number (two or four) of mini dental implants with Equator attachments. However, there was a significant difference in marginal bone loss and patient satisfaction between those receiving mini dental implants with Equator attachments and conventional dental implants with ball attachments. The marginal bone resorption in Group 3 was significantly higher than in Groups 1 and 2 (p < 0.05); there were no significant differences between Groups 1 and 2. There was no significant difference in patient satisfaction between Groups 1 and 2 but it was significantly higher than that in Group3 (p < 0.05). Two and four mini dental implants can be immediately used successfully for retaining lower complete dentures, as shown after a 1-year follow up. © 2016 Wiley Periodicals, Inc.

[Coping with everyday stress in different problem areas- comparison of clinically referred and healthy adolescents].

Studies are lacking that analyze how clinically referred adolescents and healthy adolescents cope with everyday stressors. Clinically referred adolescents from three problematic domains (diverse disorders including delinquency, drug abuse, and depression) were compared to healthy adolescents using the Coping Across Situations Questionnaire (Seiffge-Krenke, 1995) and a short version of the Youth Self-Report (Achenbach, 1991). The different clinical groups (n = 469) showed unique patterns concerning their coping styles. The group of depressed youth altogether showed lower coping activities. The youth from institutions for drug abusive youth used more dysfunctional coping. The adolescents from youth welfare services (diverse disorders including delinquency) were more active in both dysfunctional and functional coping than the other two clinically referred groups. The control group showed more functional and less dysfunctional coping. The clinically referred adolescents did not differentiate in their coping behavior, depending on the type of stressor. Gender effects were apparent, albeit negligible. Clinically referred youth are unable to adapt their coping behavior according to the given situation.

The availability of internet-based information resources is increasing and the appropriate use of such resources is an important subject for clinical medical students. The aims of this study were to investigate the behaviors of clinical medical students regarding the use of internet-based activities, to analyze the behavior and characteristics of the students' information demands, and to discuss the behaviors and time preferences related to internet use of students with different levels of education. Librarians obtained real-time feedback from 999 clinical medical students to record online activities. The data was recorded in a standard form and then analyzed statistically. There were significant differences in the use of the internet for learning activities among the different groups of clinical medical students (P < 0.0001). Learning accounted for 73.5% of all internet use for doctoral candidates, 47.6% of internet use for master's candidates, 28.7% of internet use for seven-year undergraduate students, and 14.1% of use for five-year undergraduate students. There was also a significant difference in the proportions of leisure and e-commerce activities among the student groups (P < 0.0001), with five-year students displaying the highest total proportion of these activities (59.4% and 18.8%). Internet use for entertainment activities was the same for all groups of clinical medical students. Time of day of internet use was consistent across all student groups, but internet use differed by day of the week (P < 0.01). There was no difference among the time of day of internet use for learning, leisure and entertainment activities during a single day (P > 0.05), but e-commerce activities varied according to time of day (P < 0.05). Learning and e-commerce activities by clinical medical students did not vary by day of the week (P > 0.05), but the distributions of leisure and entertainment activities were different according to day of the week (P < 0.05). A stronger demand for learning is associated with a higher academic level of clinical medical students. Differences exist among student groups regarding internet use behaviors and internet use during different time periods.

We conducted an experimental pilot study in an oncology clinic in Honolulu, Hawai'i to determine the effect of a culturally-tailored educational DVD on cancer clinical trial participation among Filipino cancer patients. Thirty-seven patients participated in the study, with 17 randomized into the control group (ie, usual education) and 20 into the intervention group (ie, usual education plus educational DVD). Participants completed pre- and post-educational questionnaires with items asking about understanding of several cancer topics, behavioral outcomes, and attitudes regarding several treatment and physician related topics. A Fisher's exact test was conducted to explore the association between enrollment into a clinical trial and group assignment. General linear models were created to determine significant differences between study groups in post-education response scores for each questionnaire item after controlling for age, gender, education, and pre-education response scores. Two participants from the control group and three participants from the intervention group enrolled into clinical trials. Results showed no significant association between clinical trial enrollment and study group assignment ( P > .99). A significant difference was found between study groups on surety of joining the clinical trial suggested to them ( P = .013). A multilingual educational DVD to supplement clinical trial education may positively influence Filipino cancer patients to move forward with the decision to join a cancer clinical trial. However, health literacy may serve as a major barrier to actual enrollment into the particular clinical trial available to a patient.

Low heart rate variability in patients with clinical burnout.

2016-12-01

Several studies have shown that acute psychosocial stress and chronic psychosocial stress reduce heart rate variability (HRV). It is likely that individuals suffering from burnout have reduced HRV, as a consequence of the long-term stress exposure. This study investigated HRV in 54 patients with clinical burnout (40 women and 14 men) and in 55 individuals reporting low burnout scores (healthy; 24 women and 31 men) and 52 individuals reporting high burnout scores (non-clinical burnout; 33 women and 19 men). The participants underwent a 300s ECG recording in the supine position. Standard deviation of normal R-R intervals (SDNN) and the root mean square of successive normal interval differences (RMSSD) were derived from time domain HRV analysis. Frequency domain HRV measures; total power (TP), low frequency power (LF), high frequency power (HF), and LF/HF ratio were calculated. All HRV measures, except LF/HF ratio, were lower in the clinical burnout patients compared to both the non-clinical burnout group and the healthy group. The difference was larger between the patients and the healthy group than between the patients and the non-clinical burnout group. HRV did not differ significantly between the non-clinical burnout group and the healthy group. Low HRV in burnout patients may constitute one of the links to associated adverse health, since low HRV reflects low parasympathetic activity - and accordingly low anabolic/regenerative activity.

Laser-assisted hatching (LAH) is recognized as a useful technology to improve clinical pregnancy rates and implantation rates. This study reports the differences between a new LAH method and two conventional LAH techniques. The authors studied 151 patients with repeated implantation failure, who were divided into three groups. In group 1, the zona pellucida (ZP) was opened using LAH (n = 52). In group 2, laser-assisted thinning was performed to dissolve the outer layer of the ZP (n = 49). In group 3, laser-assisted thinning was performed to dissolve the inner layer of the ZP (n = 50). The clinical pregnancy rates and implantation rates among the groups were compared. The results demonstrate that there are significant differences in the clinical pregnancy rates and implantation rates between group 3 and the other two groups. Performing laser-assisted thinning to dissolve the inner layer of the ZP markedly increases the pregnancy rates and implantation rates of patients with repeated implantation failure.

The purpose of this study was to assess cognitive vulnerability and response style in clinical and normal individuals. A sample of 90 individuals was selected for each of the 3 groups of Generalized Anxiety disorder, Dysthymic disorder and normal individuals. They completed MCQ and RSQ. Results analyzed by MANOVA and post hoc showed significant differences among groups. Dysthymic group and GAD reported higher scores on cognitive confidence compared to the normal group. Individuals with GAD showed highly negative beliefs about need to control thought, compared to the other groups, but in cognitive self-consciousness they have no differences with the normal group. In regard to uncontrollability, danger and positive beliefs, GAD group had higher levels than the other groups. Although normal and GAD group didn't show any significant differences in response style, there was a significant difference between Dysthymic group and other groups in all response styles.  Beliefs and meta-cognitive strategies can be distinguished between clinical and non clinical individuals. Also, findings support the Self-Regulatory Executive Function model. ary committee was effective in recognizing, designing and implementing tailored interventions for reduction of medication errors. A systematic approach is urgently needed to decrease organizational susceptibility to errors, through providing required resources to monitor, analyze and implement effective interventions.

The goals of this study were to establish prevalence of subjective memory complaints (SMC) and depressive symptoms (DS) and their relation to cognitive functioning and cognitive status in an outpatient memory clinic cohort. Two hundred forty-eight cognitively healthy controls and 581 consecutive patients with cognitive complaints who fulfilled the inclusion criteria were included in the study. A statistically significant difference (p < 0.001) between control group and patient group regarding mean SMC was detected. 7.7% of controls reported a considerable degree of SMC, whereas 35.8% of patients reported considerable SMC. Additionally, a statistically significant difference (p < 0.001) between controls and patient group regarding Beck depression score was detected. 16.6% of controls showed a clinical relevant degree of DS, whereas 48.5% of patients showed DS. An analysis of variance revealed a statistically significant difference across all four groups (control group, SCI group, naMCI group, aMCI group) (p < 0.001). Whereas 8% of controls reported a considerable degree of SMC, 34% of the SCI group, 31% of the naMCI group, and 54% of the aMCI group reported considerable SMC. A two-factor analysis of variance with the factors cognitive status (controls, SCI group, naMCI group, aMCI group) and depressive status (depressed vs. not depressed) and SMC as dependent variable revealed that both factors were significant (p < 0.001), whereas the interaction was not (p = 0.820). A large proportion of patients seeking help in a memory outpatient clinic report considerable SMC, with an increasing degree from cognitively healthy elderly to aMCI. Depressive status increases SMC consistently across groups with different cognitive status.

A total of 14 women meeting criteria for dissociative identity disorder (DID) based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]) were compared to a group of women (n = 10) with other dissociative diagnoses and a group of normal controls (n = 14) with regard to dissociativity, absorption, trauma related symptoms and hypnotizability. Both of the clinical groups reported histories of childhood trauma and attained high PTSD scores. The DID group differed significantly from the group with other dissociative diagnoses and the non-diagnosed comparison group with regard to hypnotizability, the variety of dissociative symptomatology, and the magnitude of dissociative symptomatology. However, no significant differences between the two clinical groups were detected with regard to absorption, general dissociative level, or symptoms related to traumatic stress. Results support the notion that DID can be regarded as a clinical entity which is separable from other dissociative disorders. Results also indicated that hypnotizability is the most important clinical feature of DID.

We observed the clinical effects of comprehensive nursing intervention pattern in 23G minimally invasive vitreous surgery according to the comprehensive nursing intervention table developed by our hospital, which would supply a basis for its clinical application. In this prospective study, we followed 120 patients undergoing 23G minimally invasive vitreous surgery from Xuzhou First People's Hospital from February 2013 to February 2015 and divided them into control and observation groups by a random number table (60 patients in each group). A regular nursing pattern was adopted for the control group, and a comprehensive nursing intervention pattern was adopted for the observation group. After that, a comparative analysis was made to identify the differences between the clinical effects of the two groups. Scores of cognition ratio, patient compliance and comfort level of patients in the observation group were higher than those of the control group were, and there was significant difference between the groups (P< 0.05). Complication incidence of the observation group is significantly lower than that of the control group (P<0.05). The comprehensive nursing intervention pattern developed by our hospital can improve clinical effects notably, which is of application value .We recommend it to be applied in eye diseases.

Pain biomarkers are warranted for individualized pain management. Based on different pain modulatory phenotypes, the objectives of this study were to explore the existence of subgroups within patients with nonmalignant chronic pain and to investigate differences in clinical pain and pain hypersensitivity between subgroups. Cuff algometry was performed on lower legs in 400 patients with chronic pain to assess pressure pain threshold, pressure pain tolerance, temporal summation of pain (TSP: increase in pain scores to 10 repeated stimulations), and conditioned pain modulation (CPM: increase in cuff pressure pain threshold during cuff pain conditioning on the contralateral leg). Heat detection and heat pain thresholds at clinical painful and nonpainful body areas were assessed. Based on TSP and CPM, 4 distinct groups were formed: group 1 (n = 85) had impaired CPM and facilitated TSP; group 2 (n = 148) had impaired CPM and normal TSP; group 3 (n = 45) had normal CPM and facilitated TSP; and group 4 (n = 122) had normal CPM and normal TSP. Group 1 showed more pain regions than the other 3 groups (P < 0.001), indicating that impaired CPM and facilitated TSP play an important role in widespread pain. Groups 1 and 2 compared with group 4 had lower heat pain threshold at nonpainful areas and lower cuff pressure pain tolerance (P < 0.02), indicating that CPM plays a role for widespread hyperalgesia. Moreover, group 1 demonstrated higher clinical pain scores than group 4 (P < 0.05). Although not different between subgroups, patients were profiled on demographics, disability, pain catastrophizing, and fear of movement. Future research should investigate interventions tailored towards these subgroups.

This study assessed the effects of race and place of residence on clinical trial participation by patients seen at a designated NCI comprehensive cancer center. Clinical trial accrual to cancer case ratios were evaluated using a database of residents at the continental United States seen at The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins from 2005 to 2007. Place of residence was categorized into 3 nonoverlapping geographic areas: Baltimore City, non–Baltimore City catchment area, and non–catchment area. Controlling for age, sex, county poverty level, and cancer site, significant race and place of residence differences were seen in therapeutic or nontherapeutic clinical trials participation. White non–Baltimore City catchment area residents, the designated reference group, achieved the highest participation rate. Although the test of interaction (control group compared with all others) was not significant, some race–geographic area group differences were detected. In therapeutic trials, most race–place of residence group levels were statistically lower and different from reference; in nontherapeutic trials, race-specific Baltimore City groups participated at levels similar to reference. Baltimore City residents had lower participation rates only in therapeutic trials, irrespective of race. County poverty level was not significant but was retained as a confounder. Place of residence and race were found to be significant predictors of participation in therapeutic and nontherapeutic clinical trials, although patterns differed somewhat between therapeutic and nontherapeutic trials. Clinical trial accruals are not uniform across age, sex, race, place of residence, cancer site, or trial type, underscoring that cancer centers must better understand their source patients to enhance clinical trial participation.

2012-08-01

The purpose of this study was to compare return visits made by patients within 2 weeks after using retail nurse practitioner clinics to return visits made by similar patients after using standard medical office clinics. Retail medicine clinics have become widely available. However, their impact on return visit rates compared to standard medical office visits for similar patients has not been extensively studied. Electronic medical records of adult primary care patients seen in a large group practice in Minnesota in 2009 were analyzed for this study. Patients who were treated for sinusitis were selected. Two groups of patients were studied: those who used one of 2 retail walk-in clinics staffed by nurse practitioners and a comparison group who used one of 4 regular office clinics. The dependent variable was a return office visit to any site within 2 weeks. Multiple logistic regression analysis was used to adjust for case-mix differences between groups. Unadjusted odds of return visits were lower for retail clinic patients than for standard office care patients. After adjustment for case mix, patients with more outpatient visits in the previous 6 months had higher odds of return visits within 2 weeks (2-6 prior visits: odds ratio [OR]=1.99, P=0.00; 6 or more prior visits: OR=6.80, P=0.00). The odds of a return visit within 2 weeks were not different by clinic type after adjusting for propensity to use services (OR=1.17, P=0.28). After adjusting for case mix differences, return visit rates did not differ by clinic type.

To conduct a preliminary study comparing different trauma and clinical populations on types of shame coping style and levels of state shame and guilt. A mixed independent groups/correlational design was employed. Participants were recruited by convenience sampling of 3 clinical populations-complex trauma (n = 65), dissociative identity disorder (DID; n = 20), and general mental health (n = 41)-and a control group of healthy volunteers (n = 125). All participants were given (a) the Compass of Shame Scale, which measures the four common shame coping behaviors/styles of "withdrawal," "attack self," "attack other," and "avoidance," and (b) the State Shame and Guilt Scale, which assesses state shame, guilt, and pride. The DID group exhibited significantly higher levels of "attack self," "withdrawal," and "avoidance" relative to the other groups. The complex trauma and general mental health groups did not differ on any shame variable. All three clinical groups had significantly greater levels of the "withdrawal" coping style and significantly impaired shame/guilt/pride relative to the healthy volunteers. "Attack self" emerged as a significant predictor of increased state shame in the complex trauma, general mental health, and healthy volunteer groups, whereas "withdrawal" was the sole predictor of state shame in the DID group. DID emerged as having a different profile of shame processes compared to the other clinical groups, whereas the complex trauma and general mental health groups had comparable shame levels and variable relationships. These differential profiles of shame coping and state shame are discussed with reference to assessment and treatment. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The purpose of the present study was to compare the clinical efficacy between a flowable-type nano-hybrid composite and a paste-type composite for posterior restoration. Of 62 posterior teeth in 33 patients (mean age: 34.1 years), 31 were filled with a paste-type composite (Heliomolar [HM] group), and another 31 with a flowable nano-hybrid composite (MI FIL [MI] group). Clinical efficacy was evaluated at 2 years after the restoration. There were no differences for retention, surface texture deterioration, anatomical form change, deterioration of marginal adaptation, and secondary caries, while a statistical difference was found for marginal discoloration, which was significantly greater in the HM group (P < 0.05). Furthermore, color matching in the MI group was superior to that in the HM group immediately after the restoration throughout the study period. The present 2-year clinical evaluation of different composites showed that the flowable nano-hybrid composite could be an effective esthetic material for posterior restoration. © 2016 John Wiley & Sons Australia, Ltd.

The aim of curriculum reform in medical education is to improve students' clinical and communication skills. However, there are contradicting results regarding the effectiveness of such reforms. A study of internal medicine students was carried out using a static group design. The experimental group consisted of 77 students participating in 7 sessions of communication training, 7 sessions of skills-laboratory training and 7 sessions of bedside-teaching, each lasting 1.5 hours. The control group of 66 students from the traditional curriculum participated in equally as many sessions but was offered only bedside teaching. Students' cognitive and practical skills performance was assessed using Multiple Choice Question (MCQ) testing and an objective structured clinical examination (OSCE), delivered by examiners blind to group membership. The experimental group performed significantly better on the OSCE than did the control group (P < 0.01), whereas the groups did not differ on the MCQ test (P < 0.15). This indicates that specific training in communication and basic clinical skills enabled students to perform better in an OSCE, whereas its effects on knowledge did not differ from those of the traditional curriculum. Curriculum reform promoting communication and basic clinical skills are effective and lead to an improved performance in history taking and physical examination skills.

In an attempt to develop a short neuropsychological test battery five different tests of reaction time were assessed according to their ability to discriminate between HIV seropositive men and healthy controls. In all tests a patient group with clinical symptoms was slower than the control group. In the complex reaction time test, which has a large cognitive aspect, even a clinically "asymptomatic" group was slower than the control group. The movement test, a new test with a large motor component, identified most slow responders, defining approximately half of the patients with clinical symptoms and one third of the "asymptomatic" patients as such. A test battery consisting of three tests is suggested for serial assessment and screening.

The purpose of this study was to determine if a new titanium cup with increased porosity resulted in different periacetabular bone loss and migration compared to a porous coated cup. Fifty-one patients with primary hip osteoarthritis were randomized to either a cup with porous titanium construct backside (porous titanium group, n = 25) or a conventional porous coated titanium cup (control group, n = 26). The primary outcome variable was change in periacetabular bone mineral density two years after surgery measured with dual energy X-ray absorptiometry (DXA). Secondary outcomes were implant fixation measured with radiostereometry (RSA) and clinical outcome scores. The pattern of bone remodelling was similar in the two groups with almost complete restoration to baseline values. BMD diminished in the two proximal zones and increased in the two distal zones. After minimal migration up to six months all implants in both groups became stable. We found no difference between the two groups in clinical outcome scores. In this prospective, randomized, controlled trial on a new porous titanium cup we found, compared to the control group, no clinically relevant differences regarding periacetabular bone preservation, implant fixation or clinical outcome up to two years postoperatively.

The purpose of this paper is to compare the morphological features of interictal epileptiform discharges (IED) in patients with benign epilepsy of childhood with centrotemporal spikes to IED of those with symptomatic localization related epilepsies using information theory. Three patients from each clinical group were selected. Two-second epochs centered at the peak negativity of the sharp waves were analyzed from a referential montage during stage I sleep. The epochs from the two groups were compared using parametric and information theory analysis. Information analysis determined the likelihood of correctly identifying the clinical group based on the IED. Standard parametric, morphological and spectral analyses were also performed. We found no significant difference in the morphology of the sharp wave between the two groups. The after-going slow wave contained the greatest information that separated the two groups. This result was supported by morphological and spectral differences in the after-going slow wave. Greater distinguishing information is held in the after-going slow wave than the sharp wave for the identification of clinical groups. Information analysis may assist in differentiating clinical syndromes from EEG signals.

High-fidelity simulation (HFS) offers a strategy to facilitate cognitive, affective, and psychomotor outcomes and motivate the new generation of students. The purpose of this study was to examine the impact of using high-fidelity simulation on the development of clinical judgment and motivation among Lebanese nursing students. A post-test, quasi-experimental design was used. Two private universities in Lebanon were targeted to implement the intervention. A convenience sample of 56 nursing students from two private universities in Lebanon were recruited. Data were collected using the Lasater Clinical Judgment Rubric and the Motivated Strategies for Learning questionnaires. Nursing students exhibited significant improvement in clinical judgment and motivation due to exposure to HFS. There was a significant difference post HFS between the intervention group and the control group in clinical judgment intervention (t=5.23, p<0.001) and motivation for academic achievement (t=-6.71, p<0.001). The intervention group had a higher mean score of clinical judgment (29.5, SD=5.4) than the control group (22.1, SD=5.7) and, similarly, students had higher mean scores of motivation (198.6, SD=10.5) in the intervention group than in the control group (161.6, SD=20). The analysis related to differences between the intervention and control groups in motivation and clinical judgment; controlling for previous experience in health care services, the analysis showed no significant difference (Wilk's lambda =0.77, F=1.09, p=0.374). There is a need for nursing educators to implement HFS in nursing curricula, where its integration can bridge the gap between theoretical knowledge and nursing practice and enhance critical thinking and motivation among nursing students.

β₂-Adrenergic receptor agonists accelerate resolution of pulmonary edema in experimental and clinical studies. This clinical trial was designed to test the hypothesis that an aerosolized β₂-agonist, albuterol, would improve clinical outcomes in patients with acute lung injury (ALI). We conducted a multicenter, randomized, placebo-controlled clinical trial in which 282 patients with ALI receiving mechanical ventilation were randomized to receive aerosolized albuterol (5 mg) or saline placebo every 4 hours for up to 10 days. The primary outcome variable for the trial was ventilator-free days. Ventilator-free days were not significantly different between the albuterol and placebo groups (means of 14.4 and 16.6 d, respectively; 95% confidence interval for the difference, -4.7 to 0.3 d; P = 0.087). Rates of death before hospital discharge were not significantly different between the albuterol and placebo groups (23.0 and 17.7%, respectively; 95%confidence interval for the difference,-4.0 to 14.7%;P = 0.30). In the subset of patients with shock before randomization, the number of ventilator-free days was lower with albuterol, although mortality was not different. Overall, heart rates were significantly higher in the albuterol group by approximately 4 beats/minute in the first 2 days after randomization, but rates of new atrial fibrillation (10% in both groups) and other cardiac dysrhythmias were not significantly different. These results suggest that aerosolized albuterol does not improve clinical outcomes in patients with ALI. Routine use of β₂-agonist therapy in mechanically ventilated patients with ALI cannot be recommended. Clinical trial registered with www.clinicaltrials.gov (NCT 00434993).

The purpose of this prospective clinical study was to determine the success rate of single-unit posterior fixed dental prostheses (FDPs) with zirconia copings generated with two CAD/CAM systems, compared to porcelain-fused-to-metal (PFM) single-unit posterior FDPs after 5 years of function. From 2005 to 2006, 60 patients who needed a single-unit FDP on a first molar in the mandibular jaw (left or right) in a private office setting were included in this study. The 60 first mandibular molars were randomly divided into three groups (n = 20): in the control group (group C), 20 PFM FDPs were included. In the other two groups CAD/CAM technology was used for the fabrication of the zirconium-oxide copings: 20 single-unit posterior FDPs with zirconia copings were generated with the Procera system (group P, Nobel Biocare); 20 single-unit posterior FDPs with zirconia copings were generated with the Lava system (group L, 3M ESPE). For the ANOVA follow-up data, the clinical life table method was applied. The statistical analysis was performed using two nonparametric tests, the log-rank test for k-groups and the Fisher exact test. No statistically significant difference in the clinical outcome of zirconia-ceramic FDPs of both groups (P and L) evaluated together and metal-ceramic posterior single FDPs was found at 5 years of function; however, clinical data showed that technical problems, such as extended fracture of the veneering ceramic, tended to occur more frequently in the zirconia-ceramic FDP groups. The difference in the frequency of failure was statistically significant only in the comparison of groups C and P. Even if no statistically significant difference in the clinical outcome of zirconia-ceramic FDPs of both groups (P and L) considered together and metal-ceramic posterior single FDPs was found at 5 years of function, clinical data showed that the two zirconia-ceramic FDP groups tended to have more frequent clinical problems: for this reason all the clinical and technical variables related to the use of zirconia-ceramic FDPs generated with CAD/CAM systems should be carefully considered prior to all treatment procedures. © 2012 by the American College of Prosthodontists.

Clinical ethic situations in modern multiprofessional healthcare systems may involve different healthcare professions who work together for patient care. The undergraduate interprofessional education of clinical ethics would help to incubate healthcare students' ability of interprofessional collaboration in solving ethical problems. However, the impact from an interprofessional educational model on student's attitudes and confidence of interprofessional collaboration should be carefully evaluated during the process of curricular development. This study aimed to conduct a pilot interprofessional PBL curriculum of clinical ethics and evaluate the curricular impact on interprofessional students' attitude and confidence of collaborative teamwork. Thirty-six medical and nursing students volunteered to participate in this study and were divided into three groups (medical group, nursing group, and mixed group). Tutors were recruited from the Medical School and the College of Nursing. The pilot curriculum included one lecture of clinical ethics, one PBL case study with two tutorial sessions, and one session of group discussion and feedback. A narrative story with multiple story lines and a multiperspective problem analysis tool were used in the PBL tutorials. The students' self-evaluation of learning questionnaire was used to evaluate students' learning of clinical ethics and interprofessional collaborative skills and attitude. The internal consistency of the questionnaire was measured by Cronbach α, and the criterion-related validity of the questionnaire was evaluated through associations between the dimension scores with the student group by one-way analysis of variance test (ANOVA) test and Tukey-Kramer honestly significant difference (HSD) comparison. There was significant difference among different groups in students' ability and attitudes about "interprofessional communication and collaboration" (p = 0.0184). The scores in the mixed group (37.58 ± 3.26) were higher than the medical group (32.10 ± 4.98). In conclusion, our model for the interprofessional PBL curriculum of clinical ethics is practicable and will produce positive impacts on students' attitudes and confidence of interprofessional collaboration.

High blood pressure (BP) is commonly not diagnosed, and patients do not achieve target values when treated. Among 20,000 patients encompassing most races-ethnicities, we evaluated BP measurements and treatment response in a stroke prevention trial. Our goal was to identify BP measurement differences between clinical trial and patient determinations and among the racial-ethnic groups. A total of 20,332 patients with ischemic stroke were randomized to receive antiplatelet treatment and 80 mg of telmisartan versus placebo. BP measurements were obtained at the first clinic visit and then 1 and 3 months later and every 6 months thereafter. One week after the first clinic visit, patients were requested to report a BP measurement obtained elsewhere. Measurements at the trial clinics were obtained with the same electronic device. Statistical analysis was used to detect significant differences. The mean patient age was 66 years; 36% were women, and race-ethnicity comprised 58% Whites, 33% Asian, 4.9% Hispanic, and 4% Black. Overall, 74% of patients were hypertensive. BP varied between the race-ethnicity groups, being highest in Hispanics (145/85) and lowest in Blacks (144/82). BP at visits clinic 1, nonclinic 1A, and clinic 2 were, respectively, 144/84, 137/80, and 139/81 mmHg, with the difference between visits 1-2 and visit 1A being significant. BPs were normal in 42% of the cases at visit 1A, and of these, only 44% were normal at visit 1 and 57.6% were normal on visit 2. Similar findings were noted for all race-ethnicity groups. BP values varied among race-ethnicities and showed differences between clinic and patient measurements. This finding questions the reliability of self-reported BP and has implications for BP management in daily clinical practice.

Several recent studies have reported that favorable clinical results and a high level of patient satisfaction can generally be obtained with no increased risk of complications after single-bundle anterior cruciate ligament (ACL) reconstruction performed in patients >40 years of age. However, no studies have yet clarified the age-based differences in clinical outcomes after double-bundle reconstruction. To compare clinical outcomes after double-bundle ACL reconstruction using hamstring tendon hybrid grafts between patients in 2 different age groups: ≥40 years and <40 years. Cohort study; Level of evidence, 3. A retrospective study was conducted using 96 patients (48 men, 48 women ; mean age, 37 years) who underwent unilateral ACL reconstruction between 2008 and 2011. These patients were divided into 2 groups: group M included patients ≥40 years of age (n = 40 patients), and group Y included patients <40 years of age (n = 56 patients). All patients underwent the same anatomic double-bundle ACL reconstruction procedure. Clinical outcomes were evaluated at 2 years after surgery. Tunnel enlargement was also evaluated by computed digital radiography at 1 week and 2 years after surgery. Mean postoperative side-to-side differences in anterior laxity were 0.5 ± 1.9 mm and 1.2 ± 1.5 mm in groups M and Y, respectively; there was a significant difference between the 2 groups ( P = .039). There were no significant differences between the groups in Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, or peak muscle torque of the hamstring. On the other hand, peak muscle torque of the quadriceps was significantly lower in group M (81%) than in group Y (89%) ( P = .025). With respect to femoral tunnel enlargement, the posterolateral tunnel in group M was significantly larger than that in group Y on anteroposterior and lateral radiographs ( P = .015 and P = .002, respectively). Equivalent clinical outcomes were seen between the 2 age groups after double-bundle ACL reconstruction. Postoperative anterior laxity was significantly less in older patients than in younger patients, however, older patients had significantly less quadriceps muscle strength than younger patients. Surgeons should be aware of residual muscle weakness and tunnel enlargement when performing double-bundle ACL reconstruction in older patients.

In order to make meaningful cross-cultural or cross-linguistic comparisons of health-related quality of life (HRQL) or to pool international research data, it is essential to create unbiased measures that can detect clinically important differences. When HRQL scores differ between cultural/linguistic groups, it is important to determine whether this reflects real group differences, or is the result of systematic measurement variability. To investigate the linguistic measurement equivalence of a cancer-specific HRQL questionnaire, and to conduct a sensitivity analysis of treatment differences in HRQL in a clinical trial. Patients with newly diagnosed chronic myelogenous leukemia (n = 1049) completed serial HRQL assessments in an international Phase III trial. Two types of differential item functioning (uniform and non-uniform) were evaluated using item response theory and classical test theory approaches. A sensitivity analysis was conducted to compare HRQL between treatment arms using items without evidence of differential functioning. Among 27 items, nine (33%) did not exhibit any evidence of differential functioning in both linguistic comparisons (English versus French, English versus German). Although 18 items functioned differently, there was no evidence of systematic bias. In a sensitivity analysis, adjustment for differential functioning affected the magnitude, but not the direction or interpretation of clinical trial treatment arm differences. Sufficient sample sizes were available for only three of the eight language groups. Identification of differential functioning in two-thirds of the items suggests that current psychometric methods may be too sensitive. Enhanced methodologies are needed to differentiate trivial from substantive differential item functioning. Systematic variability in HRQL across different groups can be evaluated for its effect upon clinical trial results; a practice recommended when data are pooled across cultural or linguistic groups to make conclusions about treatment effects.

Does phone multimedia messages (MMS) to families of Indigenous children with tympanic membrane perforation (TMP): (i) increase clinic attendance; (ii) improve ear health; and (iii) provide a culturally appropriate method of health promotion? Fifty-three Australian Aboriginal children with a TMP living in remote community households with a mobile phone were randomised into intervention (n = 30) and control (n = 23) groups. MMS health messages in local languages were sent to the intervention group over 6 weeks. there was no significant difference in clinic attendance, with 1.3 clinic visits per child in both groups (mean difference -0.1; 95% confidence interval (CI) -1.1, 0.9; P = 0.9). (i) there was no significant change in healed perforation (risk difference 6%; 95% CI -10, 20; P = 0.6), middle ear discharge (risk difference -1%; 95% CI -30, 30; P = 1.0) or perforation size (mean difference 3%; 95% CI -11, 17; P = 0.7) between the groups; (ii) 84% (95% CI 60, 90) in the control and 70% (95% CI 50, 80) in the intervention group were happy to receive MMS health messages in the future. The difference was not significant (risk difference -14%; 95% CI -37, 8; P = 0.3). Although there was no improvement in clinic attendance or ear health, this randomised controlled trial of MMS in Indigenous languages demonstrated that MMS is a culturally appropriate form of health promotion. Mobile phones may enhance management of chronic disease in remote and disadvantaged populations. © 2014 The Authors.

To explore differences in mindfulness facets among patients with a diagnosis of either obsessive-compulsive disorder (OCD), major depressive disorder (MDD), or borderline personality disorder (BPD), and healthy controls (HC), and their associations with clinical features. One hundred and fifty-three patients and 50 HC underwent a clinical assessment including measures of mindfulness (Five Facets Mindfulness Questionnaire - FFMQ), psychopathological symptoms (Symptom Check List-90-R), dissociation (Dissociative Experience Scale), alexithymia (Alexithymia Scale 20), and depression (Beck Depression Inventory-II). Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were performed to assess differences in mindfulness scores and their associations with clinical features. The three diagnostic groups scored lower on all mindfulness facets (apart from FFMQobserving) compared to the HC group. OCD group had a significant higher FFMQ total score (FFMQ-TS) and FFMQacting with awareness compared to the BPD group, and scored higher on FFMQdescribing compared to BPD and MDD groups. The scores in non-judging facet were significantly lower in all the three diagnostic groups compared to the HC group. Interestingly, higher FFMQ-TS was inversely related to all psychological measures, regardless of diagnostic group. Deficits in mindfulness skills were present in all diagnostic groups. Furthermore, we found disease-specific relationships between some mindfulness facets and specific psychological variables. Clinical implications are discussed. The study showed deficits in mindfulness scores in all diagnostic groups compared to a healthy control group. Overall, mindfulness construct has a significantly negative association with indexes of global distress, dissociative symptoms, alexithymia, and depression. Mindfulness-based interventions in clinical settings should take into account different patterns of mindfulness skills and their impact on disease-specific maladaptive cognitive strategies or symptomatology. © 2018 The British Psychological Society.

The validity of meta-analysis is dependent upon the quality of included studies. Here, we investigated whether the design of untreated control groups (i.e. source and timing of data collection) influences the results of clinical trials in orthodontic research. This meta-epidemiological study used unrestricted literature searching for meta-analyses in orthodontics including clinical trials with untreated control groups. Differences in standardized mean differences (ΔSMD) and their 95% confidence intervals (CIs) were calculated according to the untreated control group through multivariable random-effects meta-regression controlling for nature of the interventional group and study sample size. Effects were pooled with random-effects synthesis, followed by mixed-effect subgroup and sensitivity analyses. Studies with historical control groups reported deflated treatment effects compared to studies with concurrent control groups (13 meta-analyses; ΔSMD = -0.31; 95% CI = -0.53, -0.10; P = 0.004). Significant differences were found according to the type of historical control group (based either on growth study or clinical archive; 11 meta-analyses; ΔSMD = 0.40; 95% CI = 0.21, 0.59; P < 0.001). The use of historical control groups in orthodontic clinical research was associated with deflation of treatment effects, which was independent from whether the interventional group was prospective or retrospective and from the study's sample size. Caution is warranted when interpreting clinical studies with historical untreated control groups or when interpreting systematic reviews that include such studies. PROSPERO (CRD42015024179).

Objective Routine use of prophylactic antiepileptic drugs (AED) has been debated. We retrospectively evaluated the effects of prophylactic AED on clinical outcomes in patients with a good clinical grade suffering from aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods Between September 2012 and December 2014, 84 patients who met the following criteria were included: (1) presence of a ruptured aneurysm; (2) Hunt-Hess grade 1, 2, or 3; and (3) without seizure presentation. Patients were divided into two groups; the AED group (n = 44) and the no AED group (n = 40). Clinical data and outcomes were compared between the two groups. Results Prophylactic AEDs were used more frequently in patients who underwent microsurgery (84.1%) compared to those who underwent endovascular surgery (15.9%, p < 0.001). Regardless of prophylactic AED use, seizure episodes were not observed during the six-month follow-up period. No statistical difference in clinical outcomes at discharge (p = 0.607) and after six months of follow-up (p = 0.178) were between the two groups. After six months, however, favorable outcomes in the no AED group tended to increase and poor outcomes tended to decrease. Conclusion No difference in the clinical outcomes and systemic complications at discharge and after six months of follow-up was observed between the two groups. However, favorable outcomes in the no AED group showed a slight increase after six months. These findings suggest that discontinuation of the current practice of using prophylactic AED might be recommended in patients with a good clinical grade. PMID:26526008

The purpose of this study was to demonstrate differences in clinical presentation of hydatidiform mole between women ≥40 years and younger women. Retrospective study. A tertiary referral unit in northern Italy. Three hundred and sixty-five women with hydatidiform mole were divided into group A (<40 years, 318 cases) and group B (≥40 years, 47 cases). Clinical presentation between groups A and B was analyzed, also considering partial hydatidiform mole and complete hydatidiform mole. Differences in clinical presentation according to woman's age. In group B the diagnosis of hydatidiform mole at ≥12 gestational weeks was more frequent (p < 0.001) and the detection of ultrasound features was higher (p < 0.05) than in group A. Vaginal bleeding (p < 0.05), increased uterine volume (p < 0.0001) and hyperemesis (p < 0.05) occurred more frequently in group B. In the women with complete hydatidiform mole, group B women presented with vaginal bleeding (p < 0.001), increased uterine volume (p < 0.05) and hyperemesis (p < 0.05) more frequently than group A women. Complete hydatidiform mole was more commonly diagnosed after 12 weeks of gestation in group B (p < 0.0001). In women ≥50 years, an increased rate of disease-related complications was detected. The clinical features of hydatidiform mole in women ≥40 years are different from those seen in younger women. Failures in the early detection of hydatidiform mole in older women may expose them to a higher rate of severe complications. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Aims To compare the profile of paediatric patients receiving dental treatment under general anaesthesia (GA) or conscious sedation (CS). A second aim was to explore whether there is an overlap between the two patient groups.Design This service evaluation study was based on sociodemographic and clinical data extracted from clinical records of patients attending dental appointments for GA or CS services at King's College Hospital. Sociodemographic and clinical differences between GA and CS groups were explored using logistic regression models.Results Data from 113 children (58 GA and 55 CS) were analysed. There were differences between groups in terms of age and numbers of quadrants and teeth treated, but not in terms of sex, ethnicity or deprivation scores. In the adjusted model, older children and those having more teeth treated were more likely to be in the GA than in the CS group. An overlap between the GA and CS groups was found, with 50% of children aged four to nine years having two to four teeth treated in both groups.Conclusion Age and number of teeth treated were the main characteristics associated with receiving care under GA or CS. Some overlap between children receiving dental treatment under GA or CS existed despite demographic and clinical differences between both groups.

Background The availability of internet-based information resources is increasing and the appropriate use of such resources is an important subject for clinical medical students. The aims of this study were to investigate the behaviors of clinical medical students regarding the use of internet-based activities, to analyze the behavior and characteristics of the students’ information demands, and to discuss the behaviors and time preferences related to internet use of students with different levels of education. Methods Librarians obtained real-time feedback from 999 clinical medical students to record online activities. The data was recorded in a standard form and then analyzed statistically. Results There were significant differences in the use of the internet for learning activities among the different groups of clinical medical students (P < 0.0001). Learning accounted for 73.5% of all internet use for doctoral candidates, 47.6% of internet use for master’s candidates, 28.7% of internet use for seven-year undergraduate students, and 14.1% of use for five-year undergraduate students. There was also a significant difference in the proportions of leisure and e-commerce activities among the student groups (P < 0.0001), with five-year students displaying the highest total proportion of these activities (59.4% and 18.8%). Internet use for entertainment activities was the same for all groups of clinical medical students. Time of day of internet use was consistent across all student groups, but internet use differed by day of the week (P < 0.01). There was no difference among the time of day of internet use for learning, leisure and entertainment activities during a single day (P > 0.05), but e-commerce activities varied according to time of day (P < 0.05). Learning and e-commerce activities by clinical medical students did not vary by day of the week (P > 0.05), but the distributions of leisure and entertainment activities were different according to day of the week (P < 0.05). Conclusions A stronger demand for learning is associated with a higher academic level of clinical medical students. Differences exist among student groups regarding internet use behaviors and internet use during different time periods. PMID:24690437

To study the ultra structural changes in bladder musculature in cases of BPE and their clinical relevance. In this descriptive longitudinal, controlled, observational study patients were enrolled into three groups, group 1, group 2A and group 2B. Control group (group-1) consisted of age matched normal male patients, who underwent surveillance or diagnostic cystoscopy for microscopic hematuria or irritative symptoms. Case group (group-2) comprised of patients with BPE, undergoing TURP. Case group (group-2) was further classified into: Category 2A (patients not on catheter) and cat-egory 2B (patients on catheter). All relevant clinical parameters like IPSS, prostate size, Qmax, PVR were recorded. Cystoscopy and bladder biopsy were performed in all patients. Various ultrastructural parameters like myocytes, fascicular pattern, interstitial tissue, nerve hypertrophy and cell junction pattern were analyzed under electron microscope and they were clinically correlated using appropriate statistical tests. Control group had significant difference as compared to case group in terms of baseline parameters like IPSS, flow rate and prostate size, both preoperatively and postoperatively, except for PVR, which was seen only preoperatively. There was statistically significant difference in ultrastructural patterns between case and control group in all five electron microscopic patterns. However, no significant difference was found between the subcategories of case groups. BPE is responsible for ultra structural changes in detrusor muscle and these changes remain persistent even after TURP. Nerve hypertrophy, which was not thoroughly discussed in previous studies, is also one of the salient feature of this study. Copyright® by the International Brazilian Journal of Urology.

Although image analysis has shown that the outside-in (OI) technique is associated with different femoral tunnel geometry than the transportal (TP) technique in anatomic anterior cruciate ligament (ACL) reconstruction, it is not known whether clinical results differ between the 2 techniques. To compare clinical results, second-look arthroscopic findings, and magnetic resonance imaging (MRI) findings between the TP and OI techniques in anatomic double-bundle (DB) ACL reconstruction. Randomized controlled trial; Level of evidence, 2. From November 2010 to March 2013, 128 patients were enrolled in this study and were randomly assigned to either the TP group (64 patients) or the OI group (64 patients), and DB ACL reconstructions were performed. At the minimum 2-year follow-up (34.9 ± 10.9 months), 111 patients (86.7%) were evaluated with multiple clinical scores and stability tests (KT-2000 arthrometer, Lachman test, and pivot-shift test). Ninety-three knees were evaluated for graft continuity, graft tension, and synovialization by use of second-look arthroscopy. Seventy-eight knees were evaluated on MRI for graft continuity, femoral graft tunnel healing, and graft signal/noise quotient (SNQ). The primary outcome was KT-2000 arthrometer results. Results were compared between the TP and OI groups. No significant differences were found between the 2 groups in terms of KT-2000 arthrometer results, which was the primary outcome, and other clinical results, with the exception of the postoperative functional test of International Knee Documentation Committee (IKDC) objective score. The ratio of grade A and B on the postoperative functional test of IKDC objective score was significantly larger for the OI group (51/58) than the TP group (36/53) ( P = .005). The second-look arthroscopic findings were not significantly different between the 2 groups in either bundle ( P > .05). In addition, MRI findings did not differ significantly between the 2 groups ( P > .05). With the exception of the functional test of IKDC objective score, we found that clinical results, second-look arthroscopic findings, and MRI findings did not differ significantly between the OI and TP techniques for anatomic ACL reconstruction, although femoral tunnel geometries differed significantly between the 2 techniques.

Although reverse shoulder arthroplasty provides excellent clinical results in appropriately selected patients, loss of external and internal rotation may occur. Component selection, design, and placement affect postoperative results. Recent studies considered the effect of humeral component version on functional results. The current study investigated whether humeral stem retroversion affects the outcomes of reverse shoulder arthroplasty with a retrospective review of a multisurgeon, industry-sponsored, prospectively gathered database of a single reverse shoulder arthroplasty implant. All patients had at least 2-year follow-up. Clinical outcomes, including American Shoulder and Elbow Surgeons score, visual analog scale pain score, Short Form-12 Mental and Physical Component scores, range of motion, and internal rotation function, were compared between patients with humeral retroversion of 10° or less (group A) and those with humeral retroversion of 20° or greater (group B). Radiographic outcomes were compared. The analysis included 64 patients (group A, 29 patients; group B, 35 patients). No clinical or statistically significant difference was found in American Shoulder and Elbow Surgeons scores. Both groups showed statistical and clinical improvement vs preoperative scores, with group A averaging 77.8 and group B averaging 79.2 at final follow-up. No differences were found between groups in range of motion or ability to perform tasks that require shoulder internal rotation. Patients can expect good clinical improvement after reverse shoulder arthroplasty. No difference was found in clinical or radiologic outcomes based on humeral component retroversion. Despite the theoretical increase in external rotation when the humeral component is placed closer to native retroversion, the results did not show this effect. [Orthopedics. 2017; 40(3):179-186.].

The purpose of the present study was to compare the clinical and radiographic results after TKA using two prostheses with different sagittal patellofemoral design features, including outcomes related to compatibility of the patellofemoral joint. The clinical and radiographic results of 81 patients (100 knees) who underwent TKA using the specific prosthesis (group A) were compared with those in a control group who underwent TKA using the other prosthesis (group B). The presence of anterior knee joint pain, patellar crepitation, and patellar clunk syndrome was also checked. The function score and maximum flexion angle at the last follow-up were slightly better in group A than those in group B (92.0 ± 2.3 vs. 90.6 ± 4.2) (133.6° ± 8.4° vs. 129.6° ± 11.4°). Anterior knee pain was observed in 6 knees and patellar crepitation in four knees in group A. In group B, these symptoms were observed in 22 knees and 18 knees, respectively. There was no patellar clunk syndrome in either group. The alignment was corrected with satisfactory positioning of components. The patellar height remained unchanged after TKA in the two groups. The differences between preoperative and postoperative patellar tilt angle and patellar translation were small. When comparing the clinical and radiographic results after TKA using two prostheses with different sagittal patellofemoral design features, TKA using the specific prosthesis provided satisfactory results with less clinical symptoms related to the patellofemoral kinematics with TKA using the other prosthesis.

The effect of postmilking teat dipping with a foaming iodophor agent on incidence of intramammary infections (IMI), incidence of clinical mastitis, somatic cell count and the characteristics of udder tissue and teat was investigated in a positively controlled field study. Two groups of animals were compared. Teats were dipped with a foaming iodophor in the treatment group (TG, 122 animals) while teats in the control group (CG, 121 animals) were dipped with a conventional iodophor teat dip with the same iodine content. A bacteriological examination of quarter milk samples divided the study period in two parts. The incidence of new IMI did not differ between the groups (1st part of trial: TG vs. CG: 6.84% vs. 9.16%, 2nd part of trial: 7.78% vs. 7.82%). There were no differences between the treatment groups regarding incidence of clinical mastitis. We detected 0.64 clinical cases per 100 days in the treatment group vs. 0.50 in the control group. The development of SCC was comparable in both groups. Teat skin and teat duct conditions showed variation during the study period. Clinical efficacy of postmilking teat disinfection with a foaming iodophor was comparable to the treatment with a conventional iodophor product.

Diagnosis of incarcerated inguinal hernia (IIH) is not difficult, but currently, there are no diagnostic criteria that can be used to differentiate it from strangulated inguinal hernia (SIH). This research aimed to evaluate the clinical value of the neutrophil/lymphocyte ratio (NLR) in diagnosing SIH. We retrospectively analyzed 263 patients with IIH who had undergone emergency operation. The patients were divided into two groups according to IIH severity: group A, patients with pure IIH validated during operation as having no bowel ischemia; group B, patients with SIH validated during operation as having obvious bowel ischemia, including bowel necrosis. We statistically evaluated the relation between several clinical features and SIH. The accuracy of different indices was then evaluated and compared using receiver operating characteristic (ROC) curve analyses, and the corresponding cutoff values were calculated. Univariate analysis showed eight clinical features that were significantly different between the two groups. They were then subjected to multivariate analysis, which showed that the NLR, type of hernia, and incarcerated organ were significantly related to SIH. ROC curve analysis showed that the NLR had the largest area under the ROC curve. Among the different clinical features, the NLR appears to be the best index in diagnosing SIH.

Objective Treatment of furcation defects are thought to be challenging. The purpose of this study was to evaluate the clinical and radiographic parameters of Bio-Gen with Biocollagen compared with Bio-Gen with connective tissue in the treatment of Class II furcation defects. Material and Methods In this clinical trial, 24 patients with Class II furcation defect on a buccal or lingual mandibular molar were recruited. After oral hygiene instruction, scaling and root planing and achievement of acceptable plaque control, the patients were randomly chosen to receive either connective tissue and Bio-Gen (case group) or Biocollagen and Bio-Gen (control group). The following parameters were recorded before the first and re-entry surgery (six months later): vertical clinical attachment level (VCAL), gingival index (GI), plaque index (PI), horizontal probing depth (HPD), vertical probing depth (VPD), gingival recession (GR), furcation vertical component (FVC), furcation to alveolar crest (FAC), fornix to base of defect (FBD), and furcation horizontal component (FHC) were calculated at the time of first surgery and during re-entry. A digital periapical radiograph was taken in parallel before first surgery and re-entry. The radiographs were then analyzed by digital subtraction. The differences with p value <0.05 were considered significant. Results Only the mean changes of FAC, FHC, mean of FHC, FBD in re-entry revealed statistically significant differences between the two groups. HPD, VPD, FBD, FAC, and FHC showed statistically significant differences after 6 months in the case group. However, in the control group, statistically significant differences were found in GR and HPD. We did not observe any significant difference in radiographic changes among the two groups. Conclusion The results of this trial indicate that better clinical outcomes can be obtained with connective tissue grafts in combination with bone material compared with a resorbable barrier with bone material. The differences in radiographic changes between the two groups, however, were not statistically significant. PMID:24212988

Introduction Smoking is a hazardous habit which causes definite changes in the oral cavity, consequently there exist changes in the mucosa when subjected to smoking. Palatal mucosa is first to be affected. The present study determines the palatal status in reverse smokers and conventional smokers. Aim To study and compare the clinical, cytological and histopathological changes in palatal mucosa among reverse and conventional smokers. Materials and Methods Study sample was categorized into two groups. Group 1 comprised of 20 subjects with the habit of reverse smoking and Group 2 comprised of 20 subjects with the habit of conventional smoking. Initially, clinical appearance of the palatal mucosa was recorded, followed by a cytological smear and biopsy of the involved area among all the subjects. The findings were studied clinically, the specimens were analysed cytologically and histopathologically, and compared among the two groups. Results The severity of clinical changes of the palatal mucosa among reverse smokers was statistically significant when compared to those of conventional smokers. There was no statistically significant difference observed in cytological staging between the groups with a p-value of 0.35. The histopathological changes in both the groups showed a significant difference with a p-value of 0.02. A significant positive correlation was observed between the clinical appearance, and cytological, histopathological changes. Conclusion Profound clinically aggressive changes were observed in group I compared to group II. Severity of dysplastic changes have been detected in few subjects through histopathological examination irrespective of no prominent clinical and cytological changes observed among the two groups.

The aims of this study were to assess 1) differences in perceptions of dental implant training between dental students who received didactic training alone (control group) and those who received didactic plus simulation training (test group); 2) differences in response between students with and without clinical experience in implant dentistry; and 3) the interaction effect of simulation training and clinical experience on students' satisfaction. A survey was distributed to the control group in 2014 and to the test group in 2015; both groups were at the same U.S. dental school. Data were collected on confidence levels with various implant restorative procedures along with overall satisfaction and number of implant restorations performed by each student. The response rate was 78.7% in the control group and 81.3% in the test group. In the control group, 85.7% of students reported being satisfied with implant training compared to 90.8% of students in the test group. The interaction effect of simulation training and clinical experience on overall student satisfaction was OR=1.5 at 95% CI: 0.8, 3.0. The students who had clinical experience with implant restorative procedures had significantly greater satisfaction than those who did not (OR=4.8, 95% CI: 2.1, 11.1, p<0.01). This study found that both the simulation and clinical experience affected these students' confidence and satisfaction levels with implant education: they were almost five times more satisfied with implant training when clinical experience in implant restorative procedures was a part of their implant education.

To compare the clinical outcomes and cost-effectiveness of luteal phase down-regulation with gonadotrophin-releasing hormone (GnRH) agonist protocol and GnRH antagonist protocol in patients undergoing repeated in vitro fertilization and intracytoplasmic sperm injection (IVF-ICSI) cycles. A retrospective analysis of clinical outcomes and costs was conducted among 198 patients undergoing repeated IVF-ICSI cycles, including 109 receiving luteal phase down-regulation with GnRH agonist protocol (group A) and 89 receiving GnRH antagonist protocol (group B). The numbers of oocytes retrieved and good embryos, clinical pregnancy rate, abortion rate, the live birth rate, mean total cost, and the cost-effective ratio were compared between the two groups. In patients undergoing repeated IVF-ICSI cycles, the two protocols produced no significant differences in the number of good embryos, clinical pregnancy rate, abortion rate, or twin pregnancy rate. Compared with group B, group A had better clinical outcomes though this difference was not statistically significant. The number of retrieved oocytes was significantly greater and live birth rate significantly higher in group A than in group B (9.13=4.98 vs 7.11=4.74, and 20.2% vs 9.0%, respectively). Compared with group B, group A had higher mean total cost per cycle but lower costs for each oocyte retrieved (2729.11 vs 3038.60 RMB yuan), each good embryo (8867.19 vs 9644.85 RMB yuan), each clinical pregnancy (77598.06 vs 96139.85 RMB yuan). For patients undergoing repeated IVF/ICSI cycle, luteal phase down-regulation with GnRH agonist protocol produces good clinical outcomes with also good cost-effectiveness in spite an unsatisfactory ovarian reserve.

Double-row rotator cuff repair leads to superior cuff integrity and clinical results compared with single-row repair. The study enrolled 68 patients with a full-thickness rotator cuff tear who were divided into 2 groups of 34 patients according to repair technique. The patients were followed-up for at least 2 years. The results were evaluated by Constant score. Despite the biomechanical studies and cadaver studies that proved the superiority of double-row fixation over single-row fixation, our clinical results show no difference in functional outcome between the two methods. It is evident that double-row repair is more technically demanding, expensive, and time-consuming than single-row repair, without providing a significant improvement in clinical results. Comparison between groups did not show significant differences. At the final follow-up, the Constant score was 82.2 in the single-row group and 78.8 in the double-row group. Functional outcome was improved in both groups after surgery, but the difference between the 2 groups was not significant. At long-term follow-up, arthroscopic rotator cuff repair with the double-row technique showed no significant difference in clinical outcome compared with single-row repair in small to medium tears. 2010 Journal of Shoulder and Elbow Surgery Board of Trustees.

Hispanic cancer patients are underrepresented in clinical trials; research suggests lack of knowledge and language barriers contribute to low accrual. Multimedia materials offer advantages to Hispanic populations because they have high acceptability, are easy to disseminate, and can be viewed with family. Hispanic cancer patients and caregivers participated in focus groups to aid in developing a Spanish-language multimedia intervention to educate Hispanic cancer patients about clinical trials. We explored the feasibility of delivering the intervention in medical oncology clinics. A total of 35 patients were randomized to either the multimedia intervention group (n = 18) or a control group (n = 17) who were asked to read the National Cancer Institute's Spanish-language clinical trials brochure. Self-reported data on knowledge about and attitudes toward clinical trials, self-efficacy for participating in a clinical trial, intention to participate in a clinical trial if asked, and receptivity to information about a clinical trial were collected at baseline and 10 days later. Delivery of the multimedia presentation in oncology clinics was feasible. The intervention group had more knowledge about clinical trials at follow-up than the control group; scores for intention to participate in a clinical trial by participants in the intervention group increased from 3.8 to 4.0 of a possible 5, but declined in the control group from 4.5 to 4.1. No statistically significant difference was detected between groups in scores for attitudes or self-efficacy for making a decision to participate in a clinical trial. Our sample size was inadequate to identify differences between the informational methods. Although all patients were asked about their willingness to participate in a clinical trial, this decision was hypothetical. In addition, the study was conducted with a sample of Spanish-speaking Hispanic cancer patients at a comprehensive cancer center in Florida. Thus, the results may not generalize to other Hispanic populations. In the pilot project, we demonstrated the feasibility of delivering multimedia information to patients in medical oncology clinics. Because delivery in a clinical setting was found to be feasible, a larger study should be conducted to evaluate the efficacy of the multimedia intervention with respect to promoting accrual of Hispanic patients to clinical trials.

To observe the clinical characteristics and regular patterns of subacute 1, 2-dichloroethane poisoning patients for providing evidences to it's diagnosis, treatment and prognosis. 51 cases of subacute 1, 2-dichloroethane poisoning analyzed. They were divided into 3 groups according to their main clinical manifestation: group A mainly with intracranial hypertension (n = 25), group B with limbs tremor (n = 18), group C with mental and behavior disorder (n = 8). All cases' clinical symptoms, cranial computer tomography, cerebrospinal pressure (Group A) were observed, the durations of the onset, deterioration, improvement, recovery and whole course of the disease were compared between groups and in each group. In all of 51 cases, only the differences between the deterioration duration of cranial CT and symptom was significantly (t = 2.555, P<0.05), which indicate the deterioration of symptom was earlier than radiological change. The symptom deterioration of group C was the fastest than group A and group B (P<0.00). As to the change of symptom duration, group B's improvement, recovery and whole course was the longest comparing with group A and group C (P<0.05). As to the change of cranial CT duration, group B's recovery duration was the shortest and group A's recovery duration was the longest (P<0.01); group B's whole course was also the shortest and group A's whole course was the longest (P<0.05). The clinical course of symptoms, cranial computer tomography, cerebrospinal pressure (Group A) was compared in each group, in group A, the duration of improvement and whole course of the cranial CT and cerebrospinal pressure change was longer than that of the symptom change (P<0.01), this indicated that group A has longer asymptomatic intracranial hypertension and their cranial radiography recover slowly. In group B, their symptoms (3.94 ± 4.31 days) deteriorated is earlier than cranial CT changes (P<0.05), the recovery (92.39 ± 55.04 days) and whole course of symptom was longer than cranial CT change (all P<0.01). In group C, symptom deterioration was earlier than CT deterioration (P< 0.05). The clinical characteristic of subacute 1, 2- dichloroethane poisoning is central nervous system damage, it differs according to the different stage of course, the regions and severity of pathology lesions.

To evaluate the feasibility of full-mouth debridement (subgingival scaling and root planning, SRP) by 2 times within 1 week and compare the clinical effects of different sequences of debridement-antibiotic usage in patients with severe chronic periodontitis (CP). A double-blinded, placebo-controlled, randomized clinical trial was conducted in 30 severe CP patients (14 males and 16 females, 40.5 ± 8.4 years old on average from 35 to 60) receiving 3 different sequences of debridement-antibiotictherapy: Group A, antibiotic usage (metronidazole, MTZ, 0.2 g, tid, 7 d; amoxicillin, AMX 0.5 g, tid, 7 d) was started together with SRP (completed by 2 times in 7 d); Group B, antibiotic usage (MTZ 0.2 g, tid, 7 d; AMX 0.5 g, tid, 7 d) was started 1 d after SRP(completed by 2 times in 7 d); Group C, SRP alone[probing depth (PD), bleeding index (BI) and tooth mobility] was examined. The average full-mouth probing depth, the average full-mouth proximal probing depth (pPD), the percentage of sites with PD>5 mm (PD>5 mm%), the percentage of sites with proximal PD>5 mm (pPD>5 mm%), the average bleeding index (BI) and the percentage of sites with bleeding on probing (BOP%) were calculated. Clinical examinations were performed at baseline and 2 months post therapy. (1) Compared with baseline conditions, all the subjects showed clinical improvements in all the parameters evaluated 2 months post therapy, P<0.05. (2) Significant difference were observed in the average PD changes between Group A [(2.15 ± 0.42) mm], Group B [(1.76 ± 0.29) mm] and Group C [(1.57 ± 0.33) mm], P<0.05. No significant difference was observed in the average PD changes between Group B and Group C, P=0.354. Significant differences were observed in the average pPD changes between Group A [(2.45 ± 0.43)mm] and Group C[(1.90 ± 0.48) mm], P<0.05. No significant difference was observed in BI and BOP% changes between Group A,Group B and Group C. For patients with severe chronic periodontitis, it is safe and feasible to receive full-mouth SRP by 2 times within 1 week. The short-term (2 months) advantages in PD changes are observed in patients receiving SRP and antibiotic usage at the same time comparing with patients using antibiotics after SRP or SRP alone.

The aim of this prospective randomized control trial was to evaluate if the use of two different volumes (20-25 vs 40-45 μl) of media used for embryo transfer affects the clinical outcomes in fresh in vitro fertilization (IVF) cycles. In total, 236 patients were randomized in two groups, i.e., "low volume" group (n = 118) transferring the embryos with 20-25 μl of medium and "high volume" group (n = 118) transferring the embryos with 40-45 μl of medium. The clinical pregnancy, implantation, and ongoing pregnancy rates were compared between the two groups. No statistically significant differences were observed in clinical pregnancy (46.8 vs 54.3%, p = 0.27), implantation (23.7 vs 27.8%, p = 0.30), and ongoing pregnancy (33.3 vs 40.0%, p = 0.31) rates between low and high volume group, respectively. Higher volume of culture medium to load the embryo into the catheter during embryo transfer does not influence the clinical outcome in fresh IVF cycles. NCT03350646.

HIV-infected women need support to deal with their diagnosis as well as with the stigma attached to HIV. As part of their practical training, Master's-level psychology students negotiated with the staff of four clinics in townships in Tshwane, South Africa, to establish support groups for HIV+ women and offered to assist them in facilitating the groups. This study aimed to understand why the implementation of groups was successful in one clinic and not other clinics. The student reports on their experiences and interaction with clinic staff and clients were used as sources of data. Using qualitative data analysis, different dynamics and factors that could affect project implementation were identified in each clinic. The socio-ecological and systems theories were used to understand implementation processes and obstacles in implementation. The metaphor of building a bridge over a gorge was used to describe the different phases in and obstacles to the implementation of the intervention. Valuable lessons were learnt, resulting in the development of guiding principles for the implementation of support groups in community settings.

The aim of this short-term study was to compare the clinical efficacy of 2 different methods to treat acute periodontal abscesses. After patient selection, 100 cases of acute periodontal abscess were randomly divided into two groups. The experimental group was treated by supra- and subgingival scaling, while the control group was treated by incision and drainage. A clinical examination was carried out to record the following variables: subjective clinical variables including pain, edema, redness and swelling; objective clinical variables including gingival index(GI), bleeding index(BI), probing depth(PD),suppuration, lymphadenopathy and tooth mobility. The data was analyzed with SPSS 19.0 software package. RESULES: Subjective clinical variables demonstrated statistically significant improvements with both methods from the first day after treatment and lasted for at least 30 days(P<0.05), but the results of experimental group showed much better than the control group 1 day and 7 days after treatment. 30 days after treatment, there was no significant difference between the two groups in pain and swelling improvement(P>0.05), but the experimental group showed more improvement in edema and redness than the control group(P<0.05).On improving objective variables, the experimental group showed significant improvement in GI,BI,PD and suppuration 1 day after treatment(P<0.05).After 7 days, all objective clinical variables in the experimental group improved significantly(P<0.05) in the control group, there were significant improvements in GI,suppuration,lymphadenopathy and tooth mobility(P<0.05) but the four variables of the experimental group showed more improvement than the control group(P<0.05).After 30 days, all objective clinical variables improved significantly in both groups as compared to baseline, but in the experimental group, improvements were more significant regarding to GI,BI,PD,suppuration and tooth mobility(P<0.05). The method of supra- and subgingival scaling was rapid and effective in treatment of acute periodontal abscesses.

Total knee arthroplasty gives excellent objective results. Nevertheless, the subjective findings do not match the normal knee perception: Often, it depends on patellar pain onset. In this study, we analyzed clinical and radiological items that can affect resurfaced patellar tracking, and role of a patella-friendly femoral component and patellar size on patellar pain onset. Thirty consecutive patients were implanted using the same-cemented posterior-stabilized TKA associated with patella resurfacing. Fifteen patients were implanted using a classical femoral component, while another 15 patients were implanted using a patella-friendly femoral component. The statistical analysis was set to detect a significant difference (p < 0.05) in clinical and radiological outcomes related to several surgical parameters. Clinical and functional outcomes were recorded using the Knee Society Scoring System (KSS) and patellar pain with the Burnett questionnaire. Mean follow-up was 25 months. KSS results were excellent in both groups. Group 2 (patella-friendly femoral model) reached a higher percentage of 100 points in the clinical and functional KSS, but there was no statistical difference. Also, no statistical differences for Burnett Questionnaire results were recorded. We had one case of patellar clunk syndrome in the standard femoral component group and one poor result in the second group. Postoperative radiographic measurements evidenced no statistical differences in both groups. In group 1 (classical femoral component), better significant result (p < 0.05) war recorded at clinical evaluation according to the Knee Society Scoring System (KSS) in case of wider patellar component resurfaced. The present study reveals no statistically significant difference in the incidence of anterior knee pain between classical and "patella-friendly" femoral components. With the particular type of implant design utilized in this study, when the classical femoral component is used, bigger patellar implant sizes (38 and 41 mm) showed superior clinical outcome.

Sixty cats which underwent an ovariohysterectomy were randomly allocated into four treatment groups. One group (controls) received no analgesics postoperatively, and the others received either a single dose of buprenorphine (0.006 mg/kg) intramuscularly, or pethidine (5 mg/kg) intramuscularly, or ketoprofen (2 mg/kg) subcutaneously. The analgesia obtained after each treatment was assessed by three measures. There were significant differences between the groups both for the requirement for intervention analgesia (P = 0.0008) and for the overall clinical assessment (P = 0.0003) with ketoprofen requiring least intervention analgesia and having the best overall clinical assessment, followed by buprenorphine then pethidine. The control group required the most intervention analgesia and had the worst overall clinical assessment. Visual analogue scale scoring for pain produced significant differences between the groups from one hour after the operation, with the cats which were given ketoprofen tending to have lower pain scores than the other groups.

This study investigated the effectiveness of two different levels of e-learning when teaching clinical skills to medical students. Sixty medical students were included and randomized into two comparable groups. The groups were given either a video- or text/picture-based e-learning module and subsequently underwent both theoretical and practical examination. A follow-up test was performed 1 month later. The students in the video group performed better than the illustrated text-based group in the practical examination, both in the primary test (P<0.001) and in the follow-up test (P<0.01). Regarding theoretical knowledge, no differences were found between the groups on the primary test, though the video group performed better on the follow-up test (P=0.04). Video-based e-learning is superior to illustrated text-based e-learning when teaching certain practical clinical skills.

To investigate the clinical effect of Gushen Antai pills and progesterone in the treatment of threatened abortion, in order to provide references for early clinical intervention with threatened abortion. The 112 cases of patients with threatened abortion were randomly divided into the control group and the observation group. 56 cases in each group. Patients in the control group was injected with progesterone, the observation group was treated with Gushen Antai pills in addition to the therapy of the control group. Both groups were treated by drugs for two weeks. Their venous bloods (5 mL) were collected before treatment and in 1, 2 weeks after treatment to determine serum levels of β-HCG, P, E2 and CA125. The differences between the two groups after treatment were compared. The total effective rate of the control group and the observation group were 79% and 91.9% respectively, with a statistically significant difference between the two groups (P＜0.05). Two weeks after the treatment, the serum levels of P and E2 in the observation group were significantly higher than before treatment, but the serum CA125 levels decreased significantly after treatment (P<0.05). These indicators showed statistically significant difference compared with that of the control group (P<0.05). After treatment, the serum β-HCG levels of the two groups were significantly higher than before treatment (P<0.05), but there was no statistically significant difference between the two groups. Gushen Antai pills and progesterone had a better clinical curative effect in treatment threatened abortion, which could significantly raise serum β-HCG, P and E2, reduce serum CA125 and increase the tocolysis efficiency, and so it was worth promoted in clinic.

In this study, our aim was to assess total antioxidant capacity (TAC) levels in follicular fluid (FF) and their relationship to clinical pregnancy rates in PCOS patients undergoing assisted reproduction (ART). Twenty-two women with polycystic ovary syndrome (PCOS) (Group 1) and 41 women without PCOS (Group 2) were included in this study. Clinical and laboratory parameters and FF TAC levels were investigated. No statistically significant differences were found between the groups with regard to age and baseline parameters. Although we could not demonstrate a significant difference in FF TAC levels between the two groups (p=0.469), there was a significant positive correlation between FF TAC and clinical pregnancy rates, BMI, and the duration of infertility for the entire group (r=0.254, p=0.048; r=0.312, p=0.013; r=0.259, p=0.040; respectively). Owing to the correlation between FF TAC and the clinical pregnancy rates, further studies evaluating the impact of FF TAC levels on ART outcomes in patients with PCOS and other etiologies of infertility are needed.

Transcranial direct current stimulation (tDCS) can enhance a range of neuropsychological functions but its efficacy in addressing clinically significant emotion recognition deficits associated with depression is largely untested. A randomized crossover placebo controlled study was used to investigate the effects of tDCS over the left dorsolateral prefrontal cortex (L-DLPFC) on a range of neuropsychological variables associated with depression as well as neural activity in the associated brain region. A series of computerized tests was administered to clinical (n = 17) and control groups (n = 20) during sham and anodal (1.5 mA) stimulation. Anodal tDCS led to a significant main effect for overall emotion recognition (p = .02), with a significant improvement in the control group (p = .04). Recognition of disgust was significantly greater in the clinical group (p = .01). Recognition of anger was significantly improved for the clinical group (p = .04) during anodal stimulation. Differences between groups for each of the six emotions at varying levels of expression found that at 40% during anodal stimulation, happy recognition significantly improved for the clinical group (p = .01). Anger recognition at 80% during anodal stimulation significantly improved for the clinical group (p = .02). These improvements were observed in the absence of any change in psychomotor speed or trail making ability during anodal stimulation. Working memory significantly improved during anodal stimulation for the clinical group but not for controls (p = .03). The tentative findings of this study indicate that tDCS can have a neuromodulatory effect on a range of neuropsychological variables. However, it is clear that there was a wide variation in responses to tDCS and that individual difference and different approaches to testing and stimulation have a significant impact on final outcomes. Nonetheless, tDCS remains a promising tool for future neuropsychological research.

The aim of this study was to evaluate the clinical advantages of Roux-en-Y (R-Y) and Billroth-I (B-I) reconstruction after distal gastrectomy for gastric cancer by examining the postoperative symptoms based on a patient questionnaire and patient nutrition. In addition, this study determined which of the R-Y or B-I procedures is preferable following distal gastrectomy. Fifty-one patients who had undergone R-Y reconstruction and 50 patients who had undergone B-I reconstruction were retrospectively enrolled in this study. The operative and postoperative findings such as operating time, blood loss, complications, and postoperative hospital stay were evaluated as short-term clinical outcomes. Postoperative serum nutrition parameters, transition of body weight, incidence of residual gastritis, and clinical symptoms were evaluated as mid-term clinical outcomes. An assessment of symptoms was based on a questionnaire concerning dumping symptoms, reflux symptoms, food intake, and satisfaction with the operation. No significant differences were observed in the operative and postoperative clinical parameters without stage grouping. The transition of serum nutrition parameters revealed no significant differences between the two groups for the preoperative and postoperative states. Dumping symptoms, reflux symptoms, and abdominal symptoms were less frequent in R-Y patients, but there were no significant differences between the two groups. Moreover, the differences in body weight recovery rates were not found to be statistically significant between two groups. However, the incidence of residual gastritis was significantly less in R-Y patients (21.2%) than in B-I patients (68.8%) (p < 0.05). The questionnaire results regarding food intake and surgery satisfaction were not significantly different between the two groups. Definite clinical advantages were not recognized in patients with R-Y reconstruction. B-I and R-Y reconstructive procedures should be selected according to the condition of each patient. However, the advantages of these reconstruction procedures following distal gastrectomy would only be revealed in large randomized controlled trials.

In psychotic disorders, impairments in cognition have been associated with both clinical and functional outcome, while deficits in social cognition have been associated with functional outcome. As an extension to a recent report on neurocognition and short-term clinical outcome in first-episode psychosis (FEP), the current study explored whether social cognitive deficits could also identify poor short-term clinical outcome among FEP patients. We defined the social-cognition domain based on the scores from the Hinting Task and the Four Factor Tests of Social Intelligence. Data were collected in 45 FEP patients and 26 healthy controls. The patients were divided into good- and poor-outcome groups based on clinical data at six months following initiation of treatment. Social cognition was compared among 27 poor-outcome, 18 good-outcome, and 26 healthy-control participants. Outcome groups significantly differed in the social cognition domain (z-scores: poor outcome=-2.0 [SD=1.4]; good outcome=-1.0 [SD=1.0]; p=0.005), with both groups scoring significantly lower than the control group (p<0.003). Moreover, outcome groups differed significantly only on the Cartoon Predictions subtest (z-scores: poor outcome=-2.7 [SD=2.7]; good outcome=-0.7 [SD=1.8]; p=0.001) among the five subtests used. Overall, social cognition appears to be compromised in all FEP patients compared to healthy controls. More interestingly, significant differences in social cognitive impairments exist between good and poor short-term clinical outcome groups, with the largest effect found in the Cartoon Predictions subtest.

The aim of this study was to investigate the effects of mentoring on the clinical perioperative competence of nursing operating room students in Iran. Mentoring is an essential part of clinical education, which has been studied in different populations of students. However, there is a need to assess its effectiveness in operating room students' competence. A randomised controlled trial was performed. Sixty nursing operating room students were randomly assigned to experimental and control groups. Both the control and experimental groups had routine training in the form of faculty supervision. The experimental group had an additional mentoring program. Using the Persian Perceived Perioperative Competence Scale-Revised, clinical competence was compared between the two groups, before and after the intervention. Using SPSS 19, descriptive and inferential statistics, including chi-square and t-tests, were conducted. In the experimental group, the difference between the mean scores of clinical competence before (19·43 ± 2·80) and after (27·86 ± 1·87) the intervention was significant (p ≤ 0·001). After intervention, the difference between the mean scores of the control (3·9 ± 0·15) and experimental (8·61 ± 0·68) groups was significant (p ≤ 0·003). Findings affirmed the positive effect of mentorship programmes on clinical competence in nursing operating room students. Mentoring is an effective method for preparing nursing students in practice. Health care systems may improve as a result of staff-student relationships that ultimately increase the quality care for patients. © 2016 John Wiley & Sons Ltd.

Differences in clinical reasoning among nurses working in highly specialised paediatric care.

Andersson, Nina; Klang, Birgitta; Petersson, Gunilla

2012-03-01

The aim of the study was to examine differences in clinical reasoning among novice, experienced and specialist paediatric nurses. Highly specialised paediatric care requires specific knowledge and ongoing skill performance of the nurses employed. There is a lack of research in how paediatric nurses manage the daily care problems they encounter and how they acquire the skills required to give patients the best possible care. More knowledge is needed about how paediatric nurses with different experience and education reason and communicate about paediatric patient situations. The study was based on six recorded group discussions of a fictitious, but realistic paediatric case. Three categories of nurses: novices (n = 7), experienced (n = 7) and specialists (n = 7) from a paediatric hospital participated. A qualitative content analysis approach was chosen to examine differences in clinical reasoning. Several themes were uncovered: child's social situation, child abuse and the child's illness, qualitative differences emerged in how the nurses discussed the case. Three approaches were identified: a task-oriented approach (novices and experienced), an action-oriented approach (novices and experienced) and hypothesis-oriented approach (specialists) while discussing the case. When comparing nurses in three competence groups, it was established that the groups with extensive experience and specialist education reasoned differently than the other groups. Between the novice and experienced groups, no obvious differences were found. Thus, the importance of experience alone for the development of competence is still an open question. Experience combined with further education appears important for developing professional competence in paediatric care. Nurses' reasoning in clinical paediatric care is related to experience and training. © 2012 Blackwell Publishing Ltd.

At Wayne State University School of Medicine (WSU SOM), the Robert R. Frank Student Run Free Clinic (SRFC) is one place preclinical students can gain clinical experience. There have been no published studies to date measuring the impact of student-run free clinic (SRFC) volunteerism on clinical skills development in preclinical medical students. Surveys were given to first year medical students at WSU SOM at the beginning and end of Year 1 to assess perception of clinical skills, including self-confidence, self-reflection, and professionalism. Scores of the Year 1 Objective Structured Clinical Exam (OSCE) were compared between SRFC volunteers and non-volunteers. There were a total of 206 (68.2%) and 80 (26.5%) survey responses at the beginning and end of Year 1, respectively. Of the 80 students, 31 (38.7%) volunteered at SRFC during Year 1. Statistically significant differences were found between time points in self-confidence (p < 0.001) in both groups. When looking at self-confidence in skills pertaining to SRFC, the difference between groups was statistically significant (p = 0.032) at both time points. A total of 302 students participated in the Year 1 OSCE, 27 (9%) of which were SRFC volunteers. No statistically significant differences were found between groups for mean score (p = 0.888) and established level of rapport (p = 0.394). While this study indicated no significant differences in clinical skills in students who volunteer at the SRFC, it is a first step in attempting to measure clinical skill development outside of the structured medical school setting. The findings lend themselves to development of research designs, clinical surveys, and future studies to measure the impact of clinical volunteer opportunities on clinical skills development in future physicians.

Aims: The purpose of this study was to compare the clinical efficacy of subepithelial connective tissue graft and acellular dermal matrix graft associated with coronally repositioned flap in the treatment of Miller's class I and II gingival recession, 6 months postoperatively. Settings and Design: Ten patients with bilateral Miller's class I or class II gingival recession were randomly divided into two groups using a split-mouth study design. Materials and Methods: Group I (10 sites) was treated with subepithelial connective tissue graft along with coronally repositioned flap and Group II (10 sites) treated with acellular dermal matrix graft along with coronally repositioned flap. Clinical parameters like recession height and width, probing pocket depth, clinical attachment level, and width of keratinized gingiva were evaluated at baseline, 90th day, and 180th day for both groups. The percentage of root coverage was calculated based on the comparison of the recession height from 0 to 180th day in both Groups I and II. Statistical Analysis Used: Intragroup parameters at different time points were measured using the Wilcoxon signed rank test and Mann–Whitney U test was employed to analyze the differences between test and control groups. Results: There was no statistically significant difference in recession height and width, gain in CAL, and increase in the width of keratinized gingiva between the two groups on the 180th day. Both procedures showed clinically and statistically significant root coverage (Group I 96%, Group II 89.1%) on the 180th day. Conclusions: The results indicate that coverage of denuded root with both subepithelial connective tissue autograft and acellular dermal matrix allograft are very predictable procedures, which were stable for 6 months postoperatively.

Inference of median difference based on the Box-Cox model in randomized clinical trials.

Maruo, K; Isogawa, N; Gosho, M

2015-05-10

In randomized clinical trials, many medical and biological measurements are not normally distributed and are often skewed. The Box-Cox transformation is a powerful procedure for comparing two treatment groups for skewed continuous variables in terms of a statistical test. However, it is difficult to directly estimate and interpret the location difference between the two groups on the original scale of the measurement. We propose a helpful method that infers the difference of the treatment effect on the original scale in a more easily interpretable form. We also provide statistical analysis packages that consistently include an estimate of the treatment effect, covariance adjustments, standard errors, and statistical hypothesis tests. The simulation study that focuses on randomized parallel group clinical trials with two treatment groups indicates that the performance of the proposed method is equivalent to or better than that of the existing non-parametric approaches in terms of the type-I error rate and power. We illustrate our method with cluster of differentiation 4 data in an acquired immune deficiency syndrome clinical trial. Copyright © 2015 John Wiley & Sons, Ltd.

Evaluation and applications of the clinically significant change method with the Violence Risk Scale-Sexual Offender version: implications for risk-change communication.

We examined the use of the clinically significant change (CSC) method with the Violence Risk Scale-Sexual Offender version (VRS-SO), and its implications for risk communication, in a combined sample of 945 treated sexual offenders from three international settings, followed up for a minimum 5 years post-release. The reliable change (RC) index was used to identify thresholds of clinically meaningful change and to create four CSC groups (already okay, recovered, improved, unchanged) based on VRS-SO dynamic scores and amount of change made. Outcome analyses demonstrated important CSC-group differences in 5-year rates of sexual and violent recidivism. However, when baseline risk was controlled via Cox regression survival analysis, the pattern and magnitude of CSC-group differences in sexual and violent recidivism changed to suggest that observed variation in recidivism base rates could be at least partly explained by pre-existing group differences in risk level. Implications for communication of risk-change information and applications to clinical practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

Though hallucinations and delusions are prominent basic impairments in schizophrenia, reports of the relationship between hallucinatory and delusional symptoms among schizophrenia patients are scant. To examine the epidemiological and clinical differences between mainly hallucinatory and mainly delusional subgroups of paranoid schizophrenia patients. One hundred schizophrenia patients, paranoid type, were recruited. In a cross-sectional study, participants were divided into Mainly Hallucinatory (H) and Mainly Delusional (D) subgroups. Demographic variables were compared and clinical characteristics were evaluated using the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Clinical Global Impression Scale. The Quality-of-Life Enjoyment and Satisfaction Questionnaire-18 was used to assess quality of life. Clinically, the H group was more heterogeneous as expressed by the broader range of scores that described the clinical picture of patients in that subgroup (in 43 of 78 variables, 55.13%) and similar ranges of scores (31 of 78 variables, 39.74%) for patients in the D group. Duration of hospitalization was significantly longer in group H than in group D (p=0.047). There was no statistically significant difference between the H and D subgroups in demographic characteristics. There are distinct epidemiological and clinical differences between the H and D subgroups, with more severe positive and negative symptoms and greater functional impairment in the H group. Paranoid schizophrenia patients with prominent hallucinations have poorer prognosis and need intensive therapeutic rehabilitation beginning with onset-of-illness. Further genetic studies and comparisons of fMRI and/or PET findings are warranted to investigate additional distinctive characteristics of these subgroups.

Clinical utility of the Rorschach with African Americans.

2001-12-01

In this study we sought to identify Rorschach differences between African Americans and White Americans and to understand these differences within a social and cultural framework. Data from the Exner (1993) Comprehensive System normative sample (N = 700) was used to form a group of 44 African Americans and 44 White Americans matched for age, sex, education, and socioeconomic status. Twenty-three Rorschach variables were chosen a priori and group differences were analyzed. The only clinically significant difference found was that African Americans offered significantly less cooperative movement. This lower frequency of cooperative movement may suggest African Americans do not anticipate cooperative interactions with others as a routine event. This may reflect a shared feeling among African Americans that most members of our society are less likely to be sensitive to or responsive to their needs relative to others. However, the study demonstrates a striking similarity between the groups, supporting the clinical use of the Rorschach with African Americans.

The aim was to investigate occupational stress among newly graduated nurses in relation to the workplace and clinical group supervision. Being a newly graduated nurse is particularly stressful. What remains unclear is whether the workplace and clinical group supervision affect the stress. A cross-sectional comparative study was performed in 2012. Data were collected by means of a numerical scale measuring occupational stress, questions about workplace and clinical group supervision. One hundred and thirteen nurses who had recently graduated from three Swedish universities were included in the study. The stress was high among the newly graduated nurses but it differed significantly between workplaces, surgical departments generating the most stress. Nurses who had received clinical group supervision reported significantly less stress. The stress between workplaces remained significant also when participation in clinical group supervision was taken into account. Newly graduated nurses experience great stress and need support, especially those in surgical departments. Nurses participating in clinical group supervision reported significantly less stress. It is important to develop strategies that help to adapt the work situation so as to give nurses the necessary support. Clinical group supervision should be considered as an option for reducing stress. © 2014 John Wiley & Sons Ltd.

This paper explores the role that self-regulation and emotions play in establishing a clinical diagnosis in the context of solving a clinical case in BioWorld, a computer supported learning environment designed for medical students to practice clinical reasoning. Group differences between high and low performers were explored. The results revealed no group differences in overall measures of SRL but high performers spend more time than lows in a subcategory of the reflection phase (reflecting on prioritized evidence and results). A reciprocal role of emotions was demonstrated for clinical reasoning and predicted students' diagnostic performance. High performers showed less negative activating emotions than low performers.

Objective: To discuss the effects of prophylactic chemotherapy on the outcomes and prognosis of invasive mole patients. Methods: One hundred and fifteen invasive mole (IM) patients older than 40 years were registered in Peking Union Medical Collage Hospital.Eleven of them were treated with prophylactic chemotherapy before diagnosed as IM prophylactic chemotherapy group, while the other 104 cases received therapeutic chemotherapy after diagnosed as IM (non-prophylactic chemotherapy group). The general clinical data (including age, clinical stage, risk factor score), treatment, outcomes and relapse of patients were retrospectively compared between two groups. Results: (1) The age of prophylactic chemotherapy group and non-prophylactic chemotherapy group were (47±5) versus (46±4) years old. Ratio of clinical stageⅠ-Ⅱ were 3/11 versus 29.8% (31/104), clinical stage Ⅲ-Ⅳ were 8/11 versus 70.2% (73/104). Ratio of risk factor score 0-6 were 11/11 versus 84.6% (88/104), risk factor score >6 were 0 versus 15.4% (16/104). There were no significant statistical differences between two groups in age, clinical stage or risk factor score (all P> 0.05). (2) Treatment: the total chemotherapy courses between prophylactic chemotherapy group and non-prophylactic chemotherapy group (median 7 versus 5) were significantly different ( Z= 3.071, P= 0.002). There were no significant statistical differences between two groups in the chemotherapy courses until negative conversion of β-hCG, consolidation chemotherapy courses, total therapeutic chemotherapy courses or ratio of hysterectomy (all P> 0.05). (3) Outcomes and relapse: between the prophylactic chemotherapy group and the non-prophylactic chemotherapy group, the complete remission rate were 11/11 versus 98.1%(102/104), the relapse rate were 0 versus 1.0%(1/102). There were no significant difference between the two groups in outcomes or relapse rate ( P> 0.05). Conclusions: Prophylactic chemotherapy does not substantially benefit the IM patients older than 40 years. Prophylactic chemotherapy may not significantly improve patients' prognosis, in which increased sample size is required in further study.

To evaluate the influence of patellar replacement on total knee arthroplasty by comparing with non patellar replacement. Between September 2010 and November 2010, 63 patients (63 knees) with osteoarthritis who met the selection criteria and underwent total knee arthroplasty, were randomly divided into 2 groups: patellar replacement in 32 cases (replacement group), non patellar replacement in 31 cases (non patellar replacement group). There was no significant difference in gender, age, disease duration, osteoarthritis grading, the clinical and functional scores of American Knee Society Score (KSS), the patellar tilt angle, tibiofemoral angle, and patellar ligament ratio between 2 groups (P > 0.05), they were comparable. After 6 weeks, 3, 6, and 12 months of operation, clinical and imaging evaluation methods were used to assessment the effectiveness. Primary healing of incision was obtained in all patients of 2 groups. Deep venous thrombosis occurred in 6 cases of replacement group and in 8 cases of non patellar replacement group. All patients were followed up 12 months. The postoperative incidence of anterior knee pain in replacement group was significantly lower than that in non patellar replacement group (P < 0.05) at 3, 6, and 12 months after operation. No significant difference was found in the postoperative KSS clinical score between 2 groups at each time point (P > 0.05). The joint function score of the replacement group was significantly higher than that of the non patellar replacement group at the other time point (P < 0.05) except the score at 6 weeks and 3 months. Significant difference was found in the patella score between 2 groups at 12 months (P < 0.05), but no significant difference at the other time points (P > 0.05). X-ray film showed no patellar fracture and dislocation, or loosening and breakage of internal fixation. At 12 months after operation, the tibiofemoral angle, the patellar ligament ratio, and the patellar tilt angle showed no significant difference between 2 groups (P > 0.05). Patella replacement can improve knee function score and the patella score, and reduce the incidence of postoperative anterior knee pain.

Ankle fractures are common injuries. Since the recognition of the importance of syndesmotic injury in ankle fractures, much of the scientific work has been focused on concomitant syndesmotic injury. Despite the invention of novel devices for restoration and maintenance of the congruent syndesmosis following syndesmotic injury, the metallic syndesmotic screw is still considered to be the "gold standard". The aim of this study was to compare the clinical results in patients who retained the syndesmosis screw with those in whom the screw was removed following open reduction and internal fixation of the malleolar fracture associated with syndesmosis disruption. This was a retrospective study of 82 patients. Minimum follow-up was 12 months. Clinical evaluation included American Orthopaedic Foot and Ankle Society (AOFAS) score and Visual Analogue Scale (VAS) for patient general satisfaction. The condition of the screw (removed, intact or broken), presence of radiolucency around the syndesmotic screw and the tibiofibular clear space were recorded using final follow-up radiographs. Three cortices were engaged in 66 patients (80%) and quadricortical fixation was performed in the remaining 16 patients (20%). The number of engaged cortices did not correlate with the clinical outcome and screw fracture. A single syndesmotic screw was used in 71 patients (86%. The mean AOFAS score in the group with intact screw (I) was 83; the scores in the group with broken screw (B) and removed screw (R) were 92.5 and 85.5, respectively. There was a statistically significant difference between the three groups: this was due to the difference between groups I and B; the difference between groups I and R and groups B and R were not statistically significant. There were no statistically significant differences in VAS results. There were no statistically significant differences in clinical outcome between the group with the screw retained and the group in which the screw was removed; however, the group with broken screws had the best clinical outcome based on AOFAS score. Widening of the syndesmosis after screw removal was not evident. We do not recommend routine syndesmosis screw removal. Copyright © 2015 Elsevier Ltd. All rights reserved.

Striae distensae are very common cutaneous disorders that produce great psychological stress for women. measure and compare between efficacy and tolerability of three modalities for treatment of striae distensae. Forty-five female patients with striae distensae were randomly selected from the outpatient dermatology clinics of Al-Zahra university Hospital within 6 months period. Patients divided into three groups according to the therapeutic modalities were used. Group A: treated with carboxytherapy using carbon dioxide (CO2) injection, Group B: where patients were treated with intradermal injection of autologous platelet-rich plasma (PRP), and Group C: where we used tripolar radiofrequency (RF) for treatment. All treated groups showed overall clinical improvement as regards the width, texture, and overall improvement after treatment (P > .05), with no statistically significant differences between the three groups. Patient's satisfaction was statistically significantly better in both group C (93.33%) and group A (80%) while group B (53.33%) was less with minimal side effects such as pain and ecchymosis, which were more frequent in group B than the other two groups; but with no statistically significance differences both groups A and C were effective with no significant differences in both types of striae and in any site of the body but group B is significantly more effective on striae rubra on trunk, with better improvement of lesions texture. The three modalities of treatments proved to be effective clinically and histopathologically in treating both types of striae, which were well tolerated by the patients with minimal, transient side effects and our study results gave us guidelines for their clinical application. © 2018 Wiley Periodicals, Inc.

The evaluation of the clinical aptitude is expressed in challenging clinical situations and the scope of learning is conditioned by the quality of the educational strategy. The aim of this study was to value the scope of two different educational approaches, in order to develop the clinical aptitude of 20 family physicians. Quasi experimental design, in which 20 general physicians in training process of Family Medicine were randomized: a teaching-centered strategy (TCS) was applied in 10, and a learning-centered strategy (LCS) in the remaining 10. The application of both strategies lasted 24 hours, and the same content was used on them. While applying TCS, it was employed an exposition with questions (which privileged the transmission of information). While implementing LCS, it was used discussion in small groups (which favored the point of view and the confrontation). To validate the evaluation, it was used the Kuder-Richardson formula 20, with a reliability of 0.91. Before the intervention, TCS group had a median of 124 and LCS group, 105 (p = 0.19). After the intervention, TCS group showed a median of 126, and LCS group of 156 (p = 0.012). Both groups were compared using Mann Whitney U, and the same subjects were also compared with the matched pairs Wilcoxon test. The differences were statistically significant, which it does not differ from earlier studies. The clinical aptitude reaches best development in the LCS when tested against TCS.

To evaluate the role of endometrial injury in the cycle preceding ovarian stimulation for intrauterine insemination (IUI) cycle on the clinical pregnancy rate. This was a prospective randomized controlled trial which included three hundred and thirty two infertile women with an indication for IUI. The subjects were randomly divided into two groups. The intervention group (group A) (n=166) subjects underwent office hysteroscopy with endometrial injury using grasping forceps with teeth, while the control group (group B) (n=166) subjects underwent office hysteroscopy alone without endometrial injury. Primary outcome was clinical pregnancy rate. There were no significant differences in baseline or clinical characteristics between the groups. There were no significant differences in clinical pregnancy rate [13.8% (23/166) versus 12% (20/166); RR 1.15 (95% CI 0.66-2.01), p=0.62]. The abortion rate [4.3% (1/23) versus 15% (3/20); RR 0.29 (95% CI 0.03-2.57), p=0.27], the multiple pregnancy rate [13% (3/23) versus 15% (3/20); RR 0.87 (95% CI 0.20-3.83), p=0.85] and the live birth rate [13.6% (22/166) versus 10.4% (17/166); RR 1.28 (95% CI 0.71-2.32), p=0.42]. There is no evidence of significant difference on the clinical pregnancy rate when endometrial scratching during hysteroscopy is compared to only hysteroscopy in women undergoing IUI.

Quality of life (QOL) and sleepiness for patients with sleep apnea/hypopnea syndrome (SAHS) might improve with continuous positive airway pressure devices working in auto-adjust mode (autoCPAP) by allowing pressure modulations following patient needs. Clinical comparisons between devices driven by different algorithms are needed. We compared the clinical effectiveness of fixed pressure CPAP and four different autoCPAP devices by assessing compliance and QOL (36-item short-form health survey [SF-36]). SAHS patients were randomly allocated to five groups. Polysomnography (PSG) was performed to titrate the effective pressure in the constant CPAP group and evaluate residual apnea/hypopnea index (AHI) under autoCPAP. Follow-up consisted of clinical visits at three and six months by homecare technicians who assessed compliance, symptom scores and SF-36 scores. A laboratory-based PSG using the same CPAP/autoCPAP device as at home was performed at six months. Eighty-three patients (mean age 56+/-10 yrs) with mean body mass index (BMI) 30.8+/-5.3 kg/m(2) and severe SAHS (mean AHI: 52.3+/-17.8/h) were included. There were no differences in clinical symptoms or QOL scores, and similar clinical and PSG improvements were seen in all groups. CPAP use was >5 h per night, without any significant difference between groups. AutoCPAP is equally as effective as fixed CPAP for long-term home treatment in severe SAHS patients.

During five and a half years of studying veterinary medicine, students should in addition to theoretical knowledge acquire sufficient practical skills. Considering animal welfare and ethical aspects, opportunities for hands-on learning on living animals are limited because of the high annual number of students. The first German veterinary clinical-skills lab, established in 2013 at the University for Veterinary Medicine Hannover, Foundation (TiHo), offers opportunities for all students to learn, train and repeat clinical skills on simulators and models as frequently as they would like, until they feel sufficiently confident to transfer these skills to living animals. This study describes the establishment of clinical-skills lab training within the students' practical education, using the example of the small-animal clinic of the TiHo. Two groups of students were compared: without skills lab training (control group K) and with skills lab training (intervention group I). At the end of both the training and a subsequent 10-week clinical rotation in different sections of the clinic, an objective structured clinical examination (OSCE) was performed, testing the students' practical skills at 15 stations. An additional multiple-choice test was performed before and after the clinical rotation to evaluate the increased theoretical knowledge. Students of group I achieved significantly (p ≤ 0.05) better results in eight of the 15 tested skills. The multiple-choice test revealed a significant (p ≤ 0.05) gain of theoretical knowledge in both groups without any differences between the groups. Students displayed a high degree of acceptance of the skills lab training. Using simulators and models in veterinary education is an efficient teaching concept, and should be used continually and integrated in the curriculum.

Objective Salivary mucin and amylase levels are increased in patients with chronic periodontitis (CP). Due to the fact that aggressive periodontitis (AgP) not only differs from chronic periodontitis in terms of its clinical manifestation, the aim of this study was to compare salivary mucin and amylase levels and their relation to the clinical parameters of patients with aggressive periodontitis with that of patients with chronic periodontitis. Material and Methods Eighty subjects were divided into two groups: 20 patients with AgP and their 20 matched controls and 20 patients with CP and their 20 matched controls, based on clinical attachment loss (CAL), probing pocket depth (PPD) and bleeding on probing (BOP). Whole unstimulated saliva was obtained and mucin, amylase and protein were determined by colorimetric methods. Pearson’s correlation analysis was used to determine the relationship between salivary mucin, amylase and protein levels and the clinical parameters. Results Salivary mucin, amylase and protein levels were increased in patients with AgP and CP but there were no differences between them or between control groups. Pearson’s correlation analysis, determined in the entire subjects studied, showed a positive and significant correlation of mucin, amylase and proteins with CAL and PPD and a negative correlation with the flow rate. When Pearson’s correlation analysis was carried out in each group separately, Fisher’s z transformation showed no significant difference between both groups. Conclusion Comparison of the salivary levels of mucin, amylase and protein and their relationship with clinical parameters of AgP patients with that of CP patients revealed no differences between both groups.

Objectives: Unhelpful beliefs about sleep have been linked to insomnia, and increasing one's cognitive flexibility about sleep has been linked to post-treatment sleep improvement. This study evaluated if levels of such beliefs differ across insomnia groups, and whether there are particular beliefs that differ for specific insomnia subtypes. Methods: Participants (N = 1384) were people with insomnia and good sleepers ranging from 18 to 89 years old (M = 42.6, SD = 19.4). Data from previous studies at five insomnia clinical sites were pooled to examine responses on the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16) across differing insomnia groups. Results: Group analyses revealed that those from community-based insomnia clinics and those who are hypnotic-dependent generally had the highest levels of unhelpful sleep-related beliefs. With the exception of beliefs about sleep needs (wherein only community sleep clinic patients had high scores relative to good sleepers), all insomnia groups had higher scores on the DBAS-16 than good sleepers. A validity analysis suggested that a DBAS-16 index score > 3.8 was the level of unhelpful beliefs associated with clinically significant insomnia, although a slightly lower cutoff may be useful to identify an unhelpful degree of sleep-related beliefs in highly screened PI and medical patient groups. Conclusions: This study offers descriptive data for the use of the DBAS-16 across insomnia subgroups, which will help the user understand what degree of maladaptive sleep beliefs are most strongly associated with clinically significant levels of insomnia. Results also may have implications for cognitive targeting during treatment for particular insomnia groups. PMID:20004301

Clinical studies are needed to evaluate the entire digital and conventional workflows in prosthetic dentistry. The purpose of the second part of this clinical study was to compare the laboratory production time for tooth-supported single crowns made with 4 different digital workflows and 1 conventional workflow and to compare these crowns clinically. For each of 10 participants, a monolithic crown was fabricated in lithium disilicate-reinforced glass ceramic (IPS e.max CAD). The computer-aided design and computer-aided manufacturing (CAD-CAM) systems were Lava C.O.S. CAD software and centralized CAM (group L), Cares CAD software and centralized CAM (group iT), Cerec Connect CAD software and lab side CAM (group CiL), and Cerec Connect CAD software with centralized CAM (group CiD). The conventional fabrication (group K) included a wax pattern of the crown and heat pressing according to the lost-wax technique (IPS e.max Press). The time for the fabrication of the casts and the crowns was recorded. Subsequently, the crowns were clinically evaluated and the corresponding treatment times were recorded. The Paired Wilcoxon test with the Bonferroni correction was applied to detect differences among treatment groups (α=.05). The total mean (±standard deviation) active working time for the dental technician was 88 ±6 minutes in group L, 74 ±12 minutes in group iT, 74 ±5 minutes in group CiL, 92 ±8 minutes in group CiD, and 148 ±11 minutes in group K. The dental technician spent significantly more working time for the conventional workflow than for the digital workflows (P<.001). No statistically significant differences were found between group L and group CiD or between group iT and group CiL. No statistical differences in time for the clinical evaluation were found among groups, indicating similar outcomes (P>.05). Irrespective of the CAD-CAM system, the overall laboratory working time for a digital workflow was significantly shorter than for the conventional workflow, since the dental technician needed less active working time.

Objective. Women with infertility and recurrent miscarriages may have an overlapping etiology. The aim of this study was to compare the pregnancy loss in pregnancies after IVF treatment with spontaneous pregnancies in women with recurrent miscarriages and to assess differences related to cause of infertility. Methods. The outcome from 1220 IVF pregnancies (Group I) was compared with 611 spontaneous pregnancies (Group II) in women with recurrent miscarriages. Subgroup analysis was performed in Group I based on cause of infertility: tubal factor (392 pregnancies); male factor (610 pregnancies); and unexplained infertility (218 pregnancies). Results. The clinical pregnancy loss rate in Group I (14.3%) was significantly lower than that of Group II (25.8%, p < 0.001) and this was independent of the cause of infertility. However the timing of pregnancy loss was similar between Groups I and II. The clinical pregnancy loss rate in Group I was similar in different causes of infertility. Conclusions. The clinical pregnancy loss rate following IVF treatment is lower than that of women with unexplained recurrent miscarriages who conceived spontaneously. This difference persists whether the infertility is secondary to tubal factors, male factors, or unexplained cause. PMID:26576157

Critical reflection is effective in improving students' communication abilities and confidence. The aim of this study was to evaluate the effectiveness of a work-based critical reflection program to enhance novice nurses' clinical critical-thinking abilities, communication competency, and job performance. The present study used a quasi-experimental design. From October 2014 to August 2015, we collected data from 44 novice nurses working in an advanced general hospital in S city in Korea. Nurses in the experimental group participated in a critical reflection program for six months. Outcome variables were clinical critical-thinking skills, communication abilities, and job performance. A non-parametric Mann-Whitney U-test and a Wilcoxon rank sum test were selected to evaluate differences in mean ranks and to assess the null hypothesis that the medians were equal across the groups. The results showed that the clinical critical-thinking skills of those in the experimental group improved significantly (p = 0.003). The differences in mean ranks of communication ability between two groups was significantly statistically different (p = 0.028). Job performance improved significantly in both the experimental group and the control group, so there was no statistical difference (p = 0.294). We therefore suggest that a critical reflection program be considered an essential tool for improving critical thinking and communication abilities among novice nurses who need to adapt to the clinical environment as quickly as possible. Further, we suggest conducting research into critical reflection programs among larger and more diverse samples.

Johne's disease (JD) is an economically important infectious disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). This study evaluated the differences in various hematological and biochemical parameters between healthy goats and goats with JD. Forty goats were chosen randomly from a herd endemic for JD. A complete physical examination was performed. Blood and fresh fecal samples were collected from each goat. A complete blood cell (CBC) count and a protein electrophoresis were performed. Polymerase chain reaction (PCR) on fecal samples was performed in order to divide goats into two groups: group A "positive PCR on feces"; and group B "control (negative)." A Student's t test was performed for each parameter to verify differences between groups A vs B. Twenty goats were included in each group. Clinical signs likely related to JD were found in the history of 4/40 (10%) goats, while 36/40 (90%) goats were reported to be asymptomatic. CBC and electrophoresis values were within reference intervals in both groups. No differences were found for CBC parameters between the two groups. Values for alpha 1, beta, gamma globulins, and total protein (TP) were statistically higher in group A vs those in group B, while those for albumin and albumin/globulin (A/G) ratio were lower. An increase in TP, hypoalbuminemia, and hypergammaglobulinemia has been reported in group A, while no abnormalities were found concerning CBC. JD-positive goats seem to show earlier clinical pathological alternations than clinical signs. Protein electrophoresis may help the diagnosis of JD in asymptomatic goat herds, acting as an economical screening method.

Objectives: To investigate the relation between occlusal loading and peri-implant clinical parameters (probing depth, bleeding on probing, gingival retraction, width of keratinized mucosa, and crevicular fluid volume) in patients with implant-supported complete fixed prostheses in both arches. Material and Methods: This clinical study took place at the University of Valencia (Spain) dental clinic. It included patients attending the clinic for regular check-ups during at least 12 months after rehabilitation of both arches with implant-supported complete fixed ceramo-metallic prostheses. One study implant and one control implant were established for each patient using the T-Scan®III computerized system (Tesco, South Boston, USA). The maxillary implant closest to the point of maximum occlusal loading was taken as the study implant and the farthest (with least loading) as the control. Occlusal forces were registered with the T-Scan® III and then occlusal adjustment was performed to distribute occlusal forces correctly. Peri-implant clinical parameters were analyzed in both implants before and two and twelve months after occlusal adjustment. Results: Before occlusal adjustment, study group implants presented a higher mean volume of crevicular fluid (51.3±7.4 UP) than the control group (25.8±5.5 UP), with statistically significant difference. Two months after occlusal adjustment, there were no significant differences between groups (24.6±3.8 UP and 26±4.5 UP respectively) (p=0.977). After twelve months, no significant differences were found between groups (24.4±11.1 UP and 22.5±8.9 UP respectively) (p=0.323). For the other clinical parameters, no significant differences were identified between study and control implants at any of the study times (p>0.05). Conclusions: Study group implants receiving higher occlusal loading presented significantly higher volumes of crevicular fluid than control implants. Crevicular fluid volumes were similar in both groups two and twelve months after occlusal adjustment. Key words:Occlusal loading, crevicular fluid, peri-implant clinical parameters, T-Scan®.

In the present study, we evaluated the impact of sperm origins and concentration on the clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles. A total of 1201 ICSI cycles were retrospectively analyzed for male azoospermia or oligozoospermia between January 2015 and December 2015 in the Peking University Third Hospital. Patients were divided into three groups (Group 1 vs Group 2/3; surgically extracted sperm vs ejaculated sperms): Group 1 included 343 ICSI cycles and Group 2 analyzed 388 cycles on semen with sperm concentration <5 × 10 6 ml -1 (severe oligozoospermia group). Group 3 included 470 cycles with sperm concentration between 5 × 10 6 ml -1 and 15 × 10 6 ml -1 (mild oligozoospermia group). Fertilization rates, clinical pregnancy rates, and live birth rates were analyzed and compared among groups of different semen origins and concentrations on the oocyte retrieval day. Group 2 showed a lower fertilization rate than Group 3 (62.9% ± 21.6% vs 66.8% ± 22.1%,P< 0.05). There were no statistically significant differences in clinical pregnancy rate per transfer (51.3%, 46.7%, and 50.0%, respectively), live birth rate per transfer (44.4%, 40.9%, and 41.4%, respectively), accumulative live birth rate (58.3%, 51.0%, and 52.1%, respectively), twin birth rate (18.4%, 10.6%, and 12.6%, respectively), and birth defects rate (0, 0.3%, and 0.2%, respectively) among three groups. The results of this study indicated that sperm origins and concentration do not impact the clinical outcomes in ICSI cycles.

Tuberculosis (TB) in goats (Capra hircus) is due to infection with members of the Mycobacterium tuberculosis complex (MTC), mainly Mycobacterium bovis and Mycobacterium caprae. We report a comparative experimental infection of goats with M. bovis, M. caprae and M. tuberculosis strains. We hypothesized that goats experimentally infected with different members of the MTC would display different clinical pictures. Three groups of goats were challenged with either M. bovis SB0134 (group 1, n=5), M. caprae SB0157 (group 2, n=5) and M. tuberculosis SIT58 (group 3, n=4). The highest mean total lesion score was observed in M. bovis challenged goats (mean 15.2, range 9-19), followed by those challenged with M. caprae (10.8, 2-23). The lowest score was recorded in goats challenged with M. tuberculosis (3, 1-6). Culture results coincided with the lesion scores in yielding more positive pools (7/15) in M. bovis challenged goats. By contrast, only three pools were positive from goats challenged M. tuberculosis (3/12) and with M. caprae (3/15), respectively. Differences in the performance of the intradermal and gamma-interferon (IFN-γ) tests depending of the group were observed since all goats from group 1 were diagnosed using intradermal test and these goats reacted earlier to the IFN-γ assay in comparison to the other groups. This study confirmed that goats experimentally infected with different members of the MTC display different clinical pictures and this fact may have implications for MTC maintenance and bacterial shedding.

To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118).

Objective To investigate the clinical and antenatal sonographic characteristics of placenta previa accreta after cesarean section. Methods The data of 21 inpatients diagnosed as placenta previa accreta after cesarean section in PUMC Hospital from 2006 to 2016 were retrospectively reviewed. The clinical and ultrasound features were recorded and compared among three placental accreta groups,including placenta accrete group(n=5),increta group(n=12),and percreta group(n=4). The relationship between the placental thickness at the uterine anterior lower segment level and the blood loss of the following cesarean section was tested. Results Of 21 patients,placenta previa was diagnosed by ultrasound in 20 cases(95.2%) and placenta previa accreta was diagnosed in 9 cases(42.9%). Antenatal ultrasound findings included following signs:loss of "clear zone"(15/18,83.3%),myometrial thinning(12/18,66.7%),abnormal placental lacunae(12/19,63.2%),bladder wall interruption(2/18,11.1%),and uterovesical hypervascularity(4/9,44.4%). Myometrial thinning(J-T=64.000,P=0.036),abnormal placental lacunae(J-T=74.500,P=0.032) and the placental thickness at the uterine anterior lower segment level(U=83.000,P=0.010) showed significant difference among different placenta accreta groups. Placental thickness at the uterine anterior lower segment level showed linear correlation with the blood loss of the following cesarean section(r=0.669,P=0.002). The blood loss of the following cesarean section showed significant difference among different placenta accreta groups(U=118.500,P=0.000). Conclusions The clinical and sonographic manifestations of placenta previa accreta after cesarean section show a spectrum of demographic characteristics. The measurement of thickness of placenta at the anterior lower segment may help the evaluation of the clinical prognosis of this special pathology.

Matrices of unsplinted attachment systems are generally reported to be the weak component of implant overdentures, often requiring frequent maintenance. Clinical wear results in reduced retention of the prosthesis, requiring activation or renewal of the matrix to restore the initial level of retention. The purpose of this retrospective study was to measure the wear of the matrix of a ball attachment after various periods of clinical wear. Seventy specimens of 3 groups of matrices of ball attachments that had been in use for mean periods of 12.3 months (1Y group, n=26), 39.0 months (3Y group, n=28) and 95.6 months (8Y group, n=16) were retrieved from 35 patients (2 specimens per patient) and measured on a coordinate measuring machine equipped with a touch trigger probe. Ten unused matrices were used as controls (CTRL group). The external and internal matrix diameters and deviations from circularity were measured. For the various time periods, the decreases in matrix thickness were calculated and compared with controls. Kruskal-Wallis 1-way ANOVA by ranks, followed by the Mann-Whitney post hoc tests, were conducted to test for differences in median values among groups (α =.05). For the internal upper diameter of the matrices tested, the Kruskal-Wallis and Mann-Whitney tests revealed significant differences for the 3 groups compared to the controls. For group 1Y, a significant difference (P<.001) of the internal upper diameter was found compared to the CTRL group. Compared to the controls, the nonparametric analyses for groups 3Y and 8Y showed significant differences for the internal upper diameter (P<.001) and deviations from circularity (P<.001). For groups 1Y, 3Y and 8Y, matrix thickness losses were 07, 47 and 70 μm, respectively. Within the limitations of this study, it was observed that one year of clinical wear had limited effect on the ball attachment matrices. Three to 8 years of clinical use resulted in a significant decrease of matrix thickness, especially at the tip of the retentive lamellae.

No clinical data are available for the new computer-aided design/computer-assisted manufacture (CAD/CAM) material zirconia-reinforced lithium silicate (ZLS) ceramic. This study describes preliminary clinical results for indirect ZLS CAD/CAM restorations after 12 months. Indirect restorations were fabricated, using the CEREC method and intraoral scanning (CEREC Omnicam, CEREC MCXL). Sixty-seven restorations were seated adhesively (baseline). Sixty restorations were evaluated after 12 months (follow-up), using modified FDI criteria. Two groups were established, according to ZLS restorations' post-processing procedure prior to adhesive seating: group I (three-step polishing, n = 32) and group II (fire glazing, n = 28). Statistical analysis was performed with Mann-Whitney U test and Wilcoxon test (P < .05). The success rate of indirect ZLS CAD/CAM restorations after 12 months was 96.7%. Two restorations clinically failed as a result of bulk fracture (failure rate 3.3%). No statistically significant differences were found for baseline and follow-up criteria (Wilcoxon test, P > .05). Statistically significant differences were found for criteria surface gloss for group I and group II (Mann-Whitney U test, P < .05). This study demonstrates ZLS CAD/CAM restorations have a high clinical success rate after 12 months. A longer clinical evaluation period is necessary to draw further conclusions.

To apply rapid prototyping (RP) technology on pre-fabricating nasoalveolar molding (NAM) appliances, and compare clinical outcomes and complications with traditional NAM appliances. Between June 2014 and September 2016, 39 children with unilateral cleft lip and palate were included in study. Seventeen children (test group) had received novel NAM protocol by pre-fabricating NAM appliances using RP technology, and the other 22 children (control group) had received traditional NAM protocol. There was no significant difference in gender, age, the side of cleft lip and palate, and the width of the alveolar cleft gap before treatment between 2 groups ( P >0.05). The change of width of the alveolar cleft gap, number of clinic visit, treatment time, and complications were compared between 2 groups. The number of clinic visit was less in test group than in control group ( P <0.05). There was no significant difference in treatment time between 2 groups ( P >0.05). During treatment, there was 16 children (72.2%) of skin irritation, 3 (13.6%) of mucosal ulceration, 1 (4.5%) of intraoral bleeding, 1 (4.5%) of alveolar arch T-shap asymmetry in control group. And there were 11 children (64.7%) of skin irritation, 3 (17.6%) of mucosal ulceration in test group. There was no significant difference in the incidence of complications between 2 groups ( P >0.05). After treatment, the anterior alveolar cleft width, horizontal cleft width, sagittal cleft width, antero-medial alveolar ridges angle of the healthy side, angle between anterior alveolar and posterior alveolar baseline of the healthy side, perpendicular distance from buccal frenum point to sagittal line were significantly reduced when compared with the values before treatment ( P <0.05). The angle between the anterior segments of two sides, angle between buccal frenum point and posterior baseline were significant increased when compared with the values before treatment ( P <0.05). There was no significant difference in the differences between pre- and post-treatment of above indexes between 2 groups ( P >0.05). There also was no significant difference in posterior alveolar width, the width between the middle parts of alveolar, vertical cleft width, antero-medial alveolar ridges angle of the affected side, and angle between anterior alveolar and posterior alveolar baseline of the affected side between pre- and post-treatment in each group ( P >0.05). Clinical outcome of novel approach was equivalent to traditional protocol; however, the number of clinic visit decreased. With improving of RP technology, it would provide a more consistency and convenient way for sequential treatment with cleft lip and palate.

Although prior studies have examined various clinical characteristics of pathological gambling (PG), limited data exist regarding the clinical correlates of PG based on preferred forms of gambling. We grouped patients meeting DSM-IV criteria for pathological gambling into 3 categories of preferred forms of gambling: strategic (eg, cards, dice, sports betting, stock market), nonstrategic (eg, slots, video poker, pull tabs), or both. We then compared the groups' clinical characteristics, gambling severity (using the Yale-Brown Obsessive Compulsive Scale Modified for Pathological Gambling, the Clinical Global Impression-Severity scale, and time and money spent gambling) and psychiatric comorbidity. The 440 patients included in this sample (54.1% females; mean age 47.69±11.36 years) comprised the following groups: strategic (n = 56; 12.7%), nonstrategic (n = 200; 45.5%), or both (n = 184; 41.8%). Nonstrategic gamblers were significantly more likely to be older and female. Money spent gambling, frequency of gambling, gambling severity, and comorbid disorders did not differ significantly among groups. These preliminary results suggest that preferred form of gambling may be associated with certain age groups and sexes but is not associated with any specific clinical differences.

The impact of clinical experience on learning outcome from a resuscitation course has not been systematically investigated. To determine whether half a year of clinical experience before participation in an Advanced Life Support (ALS) course increases the immediate learning outcome and retention of learning. This was a prospective single blinded randomised controlled study of the learning outcome from a standard ALS course on a volunteer sample of the entire cohort of newly graduated doctors from Copenhagen University. The outcome measurement was ALS-competence assessed using a validated composite test including assessment of skills and knowledge. The intervention was half a year of clinical work before an ALS course. The intervention group received the course after a half-year of clinical experience. The control group participated in an ALS course immediately following graduation. Invitation to participate was accepted by 154/240 (64%) graduates and 117/154 (76%) completed the study. There was no difference between the intervention and control groups with regard to the immediate learning outcome. The intervention group had significantly higher retention of learning compared to the control group, intervention group mean 82% (CI 80-83), control group mean 78% (CI 76-80), P=0.002. The magnitude of this difference was medium (effect size=0.57). Half a year of clinical experience, before participation in an ALS course had a small but statistically significant impact on the retention of learning, but not on the immediate learning outcome.

To study the clinical effects of Shen-nourishing and menstruation-regulating method (SNMRM) combined with Triptorelin Acetate Injection (TAI) on patients with luteinized unruptured follicle syndrome (LUFS). Sixty-two LUFS patients were randomly assigned to the treatment group and the control group. TAI was given to patients in the control group while SNMRM + TAI was given to those in the treatment group. The ovulation rate and the pregnancy rate were observed in the two groups. The ovulation rate in the treatment group was higher than that in the control group, but without significant difference (85.53% versus 79.07%, P > 0.05). The pregnancy rate was significantly higher in the treatment group than in the control group (56.25% vs 30.00%, P < 0.05). Treatment of LUFS by SNMRM + TAI could improve the ovulation rate and the pregnancy rate, indicating that LUFS patients' ovary functions could be improved by using different menstruation regulating methods during different follicular development phases.

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.

Retrospective study of 68 patients of symptomatic cervical spondylosis who were treated by anterior cervical discectomy and fusion (ACDF). The purpose of this study was to compare the clinical and radiological outcomes of patients with single level cervical spondylosis using either zero-profile spacer (group A) or anterior cervical plate and cage (group B). Clinical and radiological data of 68 patients undergoing ACDF from C3-C7 were collected retrospectively. There were 35 patients with a mean age of 54.05 years who received treatment by zero-profile implant. A total of 33 patients with a mean age of 52.09 years underwent fusion by traditional plate with cage. Group A and group B were followed up for an average of 23.68 months and 24.39 months, respectively. Age, blood loss, and operation time were assessed. The clinical outcomes were evaluated by JOA and VAS score before and after surgery. In addition, incidence of dysphagia was recorded. The Cobb angle (from C2 to C7) change was measured on the lateral cervical spine radiographs. There was no significant difference in terms of operation time and blood loss between two groups. The postoperative JOA significantly increased and the VAS decreased correspondently in both groups. The postoperative Cobb angle increased and showed statistical difference compared with preoperative Cobb angle in both groups. There was no significant difference between group A and group B in achieving clinical symptoms and radiograph improvement according to postoperative JOA, VAS and Cobb angle comparison. The incidence of postoperative dysphagia was lower in the group A than group B. Our study suggests that the application of zero-p spacer can achieve similar clinical and radiological improvement compared with traditional plate and cage. Meanwhile, zero-p is superior to plate and cage with a lower incidence of postoperative dysphagia.

Alzheimer disease results in progressive functional decline, leading to loss of independence. To determine whether collaborative care plus 2 years of home-based occupational therapy delays functional decline. Randomized, controlled clinical trial. (ClinicalTrials.gov: NCT01314950). Urban public health system. 180 community-dwelling participants with Alzheimer disease and their informal caregivers. All participants received collaborative care for dementia. Patients in the intervention group also received in-home occupational therapy delivered in 24 sessions over 2 years. The primary outcome measure was the Alzheimer's Disease Cooperative Study Group Activities of Daily Living Scale (ADCS ADL); performance-based measures included the Short Physical Performance Battery (SPPB) and Short Portable Sarcopenia Measure (SPSM). At baseline, clinical characteristics did not differ significantly between groups; the mean Mini-Mental State Examination score for both groups was 19 (SD, 7). The intervention group received a median of 18 home visits from the study occupational therapists. In both groups, ADCS ADL scores declined over 24 months. At the primary end point of 24 months, ADCS ADL scores did not differ between groups (mean difference, 2.34 [95% CI, -5.27 to 9.96]). We also could not definitively demonstrate between-group differences in mean SPPB or SPSM values. The results of this trial are indeterminate and do not rule out potential clinically important effects of the intervention. The authors could not definitively demonstrate whether the addition of 2 years of in-home occupational therapy to a collaborative care management model slowed the rate of functional decline among persons with Alzheimer disease. This trial underscores the burden undertaken by caregivers as they provide care for family members with Alzheimer disease and the difficulty in slowing functional decline.

This split-mouth controlled randomized clinical trial evaluated clinical and histological results of acellular dermal matrix allograft (ADM) compared to autogenous free gingival graft (FGG) for keratinized tissue augmentation. Twenty-five patients with the absence or deficiency of keratinized tissue (50 sites) were treated with FGG (control group) and ADM (test group). Clinical parameters included keratinized tissue width (KTW) (primary outcome), soft tissue thickness (TT), recession depth (RD), probing depth (PD), and clinical attachment level (CAL). Esthetic perception was evaluated by patients and by a calibrated periodontist using visual analog scale (VAS). Histological analysis included biopsies of five different patients from both test and control sites for each evaluation period (n = 25). The analysis included percentage of connective tissue components, epithelial luminal to basal surface ratio, tissue maturation, and presence of elastic fibers. Data were evaluated by ANOVA complemented by Tukey's tests (p < 0.05). After 6 months, PD and CAL demonstrated no differences between groups. ADM presented higher RD compared to FGG in all periods. Mean tissue shrinkage for control and test groups was 12.41 versus 55.7%. TT was inferior for ADM group compared to FGG. Esthetics perception by professional evaluation showed superior results for ADM. Histomorphometric analysis demonstrated higher percentage of cellularity, blood vessels, and epithelial luminal to basal surface ratio for FGG group. ADM group presented higher percentage of collagen fibers and inflammatory infiltrate. Both treatments resulted in improvement of clinical parameters, except for RD. ADM group presented more tissue shrinkage and delayed healing, confirmed histologically, but superior professional esthetic perception. This study added important clinical and histological data to contribute in the decision-making process between indication of FGG or ADM.

Objectives: To examine the effects on bone tissues of immediate implant-supported mandibular overdentures with cusped or cuspless teeth. Methods: A randomized controlled trial was conducted at the Dental Clinic, Faculty of Dentistry, Al-Azhar University, Assiut Branch, Egypt, over a 12-month period from September 2013 to September 2014. Twenty patients were treated with immediate implant-supported overdentures: one group received overdentures with cusped teeth, and the other group received overdentures with cuspless teeth. The rate of implant success was assessed clinically and radiographically at 3, 6, 9, and 12 months. The data were collected by a questionnaire, an observation checklist, and radiography. The data were then analyzed using computerized methods. Results: Overdentures with cusped teeth showed a significant improvement in the clinical criteria, including the absence of clinical implant mobility, pain, and bone resorption, while the clinical criteria for the absence of peri-implant radiolucency were insignificantly different between the 2 groups (p>0.05). There were no significant differences in the clinical evaluations for bone levels at the time of insertion or 3 months after insertions, while significant differences were found at 6, 9, and 12 months after insertion. Conclusion: Overdentures with cusped teeth supported by immediate implants were found superior regarding many clinical criteria than those cuspless counterparts. PMID:26739979

Age-related invariance of abilities measured with the Wechsler Adult Intelligence Scale-IV.

2016-11-01

Assessment of measurement invariance across populations is essential for meaningful comparison of test scores, and is especially relevant where repeated measurements are required for educational assessment or clinical diagnosis. Establishing measurement invariance legitimizes the assumption that test scores reflect the same psychological trait in different populations or across different occasions. Examination of Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) U.S. standardization samples revealed that a first-order 5-factor measurement model was best fitting across 9 age groups from 16 years to 69 years. Strong metric invariance was found for 3 of 5 factors and partial intercept invariance for the remaining 2. Pairwise comparisons of adjacent age groups supported the inference that cognitive-trait group differences are manifested by group differences in the test scores. In educational and clinical settings these findings provide theoretical and empirical support to interpret changes in the index or subtest scores as reflecting changes in the corresponding cognitive abilities. Further, where clinically relevant, the subtest score composites can be used to compare changes in respective cognitive abilities. The model was supported in the Canadian standardization data with pooled age groups but the sample sizes were not adequate for detailed examination of separate age groups in the Canadian sample.

Until now, there are no definitive conclusions regarding functional differences related to middle- and long-term everyday activities and patient pain following implantation of mobile- and fixed-platform tibial prostheses. The aim of this study was to determine whether there are middle-term differences in knee function and pain in patients undergoing fixed- and mobile-bearing total knee arthroplasty (TKA). Eligible patients were randomized into two groups: the first group received TKA implantation with a fixed tibial platform (group A); the second group received TKA with a mobile tibial platform (group B). Patients were followed up (2 years), and their symptoms and limitations in daily living activities were evaluated using the Knee Outcome Survey-Activities of Daily Living Scale (ADLS), in addition to pain evaluation assessed using the pain visual analogue scale (VAS). There were no significant differences in function and symptoms in the ADLS and VAS between the study groups. The type of platform used in TKA (fixed vs. mobile) does not change the symptoms, function or pain of patients 2 years post-surgery. Although mobile TKAs may have better short-term results, at medium- and long-term follow-up they do not present important clinical differences compared with fixed-platform TKAs. This information is important so that surgeons can choose the most suitable implant for each patient. Randomized clinical trial, Level I.

In the Texas Medication Algorithm Project (TMAP), patients were given algorithm-guided treatment (ALGO) or treatment as usual (TAU). The ALGO intervention included a clinical coordinator to assist the physicians and administer a patient and family education program. The primary comparison in the schizophrenia module of TMAP was between patients seen in clinics in which ALGO was used (n = 165) and patients seen in clinics in which no algorithms were used (n = 144). A third group of patients, seen in clinics using an algorithm for bipolar or major depressive disorder but not for schizophrenia, was also studied (n = 156). The ALGO group had modestly greater improvement in symptoms (Brief Psychiatric Rating Scale) during the first quarter of treatment. The TAU group caught up by the end of 12 months. Cognitive functions were more improved in ALGO than in TAU at 3 months, and this difference was greater at 9 months (the final cognitive assessment). In secondary comparisons of ALGO with the second TAU group, the greater improvement in cognitive functioning was again noted, but the initial symptom difference was not significant.

Clinical review: Ethnic differences in bone mass--clinical implications.

PubMed

Leslie, William D

2012-12-01

Differences in bone mineral density (BMD) as assessed with dual-energy x-ray absorptiometry are observed between geographic and ethnic groups, with important implications in clinical practice. PubMed was employed to identify relevant studies. A review of the literature was conducted, and data were summarized and integrated. The available data highlight the complex ethnic variations in BMD, which only partially account for observed variations in fracture rates. Factors contributing to ethnic differences include genetics, skeletal size, body size and composition, lifestyle, and social determinants. Despite BMD differences, the gradient of risk for fracture from BMD and other clinical risk factors appears to be similar across ethnic groups. Furthermore, BMD variation is greater within an ethnic population than between ethnic populations. New imaging technologies have identified ethnic differences in bone geometry, volumetric density, microarchitecture, and estimated bone strength that may contribute to a better understanding of ethnic differences in fracture risk. Factors associated with ethnicity affect BMD and fracture risk through direct and indirect mechanisms.

Physiotherapists practicing at clinical placement sites assigned the role as clinical instructors (CIs), are responsible for supervising physiotherapy students. For CIs to role model evidence-based practice (EBP) they need EBP competence. The aim of this study was to assess the short and long term impact of a six-month multifaceted and clinically integrated training program in EBP on the knowledge, skills, beliefs and behaviour of CIs supervising physiotherapy students. We invited 37 CIs to participate in this non-randomized controlled study. Three self-administered questionnaires were used pre- and post-intervention, and at six-month follow-up: 1) The Adapted Fresno test (AFT), 2) the EBP Belief Scale and 3) the EBP Implementation Scale. The analysis approach was linear regression modeling using Generalized Estimating Equations. In total, 29 CIs agreed to participate in the study: 14 were invited to participate in the intervention group and 15 were invited to participate in the control group. One in the intervention group and five in the control group were lost to follow-up. At follow-up, the group difference was statistically significant for the AFT (mean difference = 37, 95% CI (15.9 -58.1), p < 0.001) and the EBP Beliefs scale (mean difference = 8.1, 95% CI (3.1 -13.2), p = 0.002), but not for the EBP Implementation scale (mean difference = 1.8. 95% CI (-4.5-8.1), p = 0.574). Comparing measurements over time, we found a statistically significant increase in mean scores related to all outcome measures for the intervention group only. A multifaceted and clinically integrated training program in EBP was successful in improving EBP knowledge, skills and beliefs among CIs. Future studies need to ensure long-term EBP behaviour change, in addition to assessing CIs' abilities to apply EBP knowledge and skills when supervising students.

The purpose of this study is to ascertain if clinical nurse specialist students differed on measures of professional socialization based on employment in a Magnet-oriented hospital. A secondary analysis of data from a previous national study of the socialization of clinical nurse specialist students was used. Anticipatory socialization variables (nursing leadership, workplace exposure to the role, and preconceived impression of the role), mentorship by a clinical nurse specialist, and socialization outcomes (self-concept, perceived preparedness for practice, and nursing specialty certification) were explored. Data were divided into 2 groups: Magnet (n = 106) and non-Magnet (n = 119). Comparisons between the groups on researcher-designed items and the Professionalism and Work Ethic subscales of the Nurses Self-Description Form were analyzed. The Magnet group was more likely to be exposed to the clinical nurse specialist role in the workplace. Overall, there were no group differences in socialization outcome measures; but in the subset of students with workplace exposure to the role, those with Magnet experience had higher professionalism self-concept scores. Magnet employment was not a significant socializing factor for nurses pursuing clinical nurse specialist education. The graduate program is likely the primary socializing agent for these students.

This study sought to investigate the clinical efficacy of arthroscopic refreshing treatment of anterior cruciate ligament (ACL) injury combined with stable medial meniscus ramp injury. Sixty-eight patients treated between January 2010 and January 2014 were included, and their clinical data were retrospectively analyzed. All patients, after being treated using ACL reconstruction, were divided into 2 groups according to meniscus injury treatment method. The observation group (31 cases) was treated by arthroscopic refreshing, which removed the tissue on both sides of the tear edge using a cutting knife, while the control group (37 cases) was treated using Fast-fix sutures. All patients were followed up for at least 24 months. Surgical duration, postoperative function recovery time, and hospital stay for patients in the observation group were significantly shorter than for those of the control group (P<0.05). Both groups showed significant post-operative improvement for Lysholm scores, IKDC scores, and average knee range of motion at 12 and 24 months post-operation (P<0.05), but no significant differences between groups were observed (P>0.05). Regarding the difference in movement range between the healthy and injured sides, both groups showed significant decrease post-operation (P<0.05). Ultimately, there was no significant difference in the recovery of ramp damage and objective symptoms between the two groups (P>0.05). Arthroscopic refreshing treatment of patients with anterior cruciate ligament injury combined with stable ramp lesion can achieve similar clinical curative effects as the Fast-fix suture, thereby providing a simple alternative for patient treatment worth popularizing.

The popular belief advocates the use of sitz (sitting) baths with cold water for the treatment of acute anal pain, but clinical practice guides recommend the use of hot water for its known effect on the at-rest anal pressure. The objective of the study was to examine the analgesic effect on the quality of life, manometer data and clinical progress, of the two temperatures in sitz baths in patients with anal pain. A randomised clinical trial on patients with acute anal pain due to haemorrhoids or anal fissures, divided into Group 1: Sitz baths with water at a temperature of less than 15 degrees C, and Group 2: Baths with a water temperature above 30 degrees C. The analgesia was the same in both groups. An analysis was made of the pain at 7 days (visual analogue scale), quality of life (SF-36), anal at-rest pressure and disease progress. Of the 27 eligible patients, 24 were randomised (Group 1: n=12 y Group 2: n=12). There were no statistical differences in pain, but it remained stable in Group 1, but gradually decreased in the patients of Group 2, the difference being in the pain scores on the first day compared to the seventh in Group 2 (p=0.244). The rest of the variables were similar. There were no statistically significant differences in pain control from day 1 to day 7 in the Group with sitz baths with hot water.

To compare the clinical efficacy and drug-related adverse effects of 14 days of treatment with cefuroxime axetil 30 mg/kg/day or phenoxymethyl penicillin 100,000 IU/kg/day in the treatment of children with erythema migrans. Consecutive patients younger than 15 years, referred to our institution in 1996 with solitary erythema migrans and without prior antibiotic therapy, were included in this prospective study. Basic demographic features and clinical data were collected by questionnaire. The efficacy of the treatment of acute disease, development of major and/or minor manifestations of Lyme borreliosis and drug-related adverse effects were surveyed at follow-up visits during the first year after the initiation of antibiotic treatment. Forty-six patients received cefuroxime axetil (group C) and 44, phenoxymethyl penicillin (group P). The two groups differed in terms of age (patients in group C were younger), but no other differences in demographic and clinical pre-treatment characteristics were present. The clinical course during the post-treatment period revealed no significant differences between the two groups: the duration of erythema migrans (7.1 +/- 7.5 days in group C, 10.6 +/- 19.3 days in group P) and the appearance of minor manifestations of Lyme borreliosis (8.8% in group C, 9.1% in group P) were comparable; no major manifestations were recorded. Twelve months after antibiotic treatment all patients were free of symptoms. The patients treated with cefuroxime axetil had more drug-related adverse effects than did those treated with phenoxymethyl penicillin (26.1% versus 6.8%, p = 0.0301). "Herxheimer's reaction" at the beginning of treatment was identified more often in group C than in group P, but the difference was not statistically significant. Cefuroxime axetil and phenoxymethyl penicillin are equally effective in the treatment of children with solitary erythema migrans; however drug-related adverse effects were more frequently observed with cefuroxime axetil.

Air emboli released from incompletely deaired cardiac chambers may cause neurocognitive decline after open heart surgery. Carbon dioxide (CO2) field flooding is reported to reduce residual intracavital air during cardiac surgery. A protective effect of carbon dioxide insufflation on postoperative brain function remains unproven in clinical trials. Eighty patients undergoing heart valve operations by median sternotomy were randomly assigned to either CO2 insufflation (group I, n = 39) or unprotected controls (group II, n = 41). Preoperative evaluation included neurocognitive test batteries consisting of six different tests, and objective measurements of brain function by means of P300 wave auditory-evoked potentials (peak latencies, ms). Neurocognitive testing and P300 measurements were repeated on postoperative day 5. Neurocognitive deficit (ND) was defined as a 20% decrement in two or more tests. Preoperatively, P300 peak latencies did not differ between groups (374 +/- 75 vs 366 +/- 72 ms, not significant [n.s.]). Five days after surgery, P300 peak latencies were significantly shorter with CO2 protection as compared with the unprotected control group (group I: 390 +/- 68 ms, group II: 429 +/- 75 ms, p = 0.02). Clinical outcome was comparable as for mortality (group I: 1 patient; group II: 2 patients) and cerebrovascular events or confusional syndromes (group I: 5 patients; group II: 4 patients) or other clinical variables as intubation time or hospital stay. Neurocognitive test batteries did not reveal differences between groups. Shorter P300 peak latencies after surgery indicate less brain damage in patients who underwent heart valve operations with CO2 flooding of the thoracic cavity. Even if these findings were not supported by clinical results or neurocognitive test batteries in our cohort, carbon dioxide field flooding has proven efficiency and should be advocated for all patients undergoing open heart surgery.

To have in-depth analysis of clinical ablation effect of noninvasive radiofrequency field-induced hyperthermia on liver cancer cells, this paper collected liver cancer patients' treatment information from 10 hospitals during January 2010 and December 2011, from which 1050 cases of patients were randomly selected as study object of observation group who underwent noninvasive radiofrequency field-induced hyperthermia treatment; in addition, 500 cases of liver cancer patients were randomly selected as study object of control group who underwent clinical surgical treatment. After treatment was completed, three years of return visit were done, survival rates of the two groups of patients after 1 year, 2 years, and 3 years were compared, and clinical effects of radiofrequency ablation of liver cancer were evaluated. Zoom results show that the two groups are similar in terms of survival rate, and the difference is without statistical significance. 125 patients in observation group had varying degrees of adverse reactions, while 253 patients in control group had adverse reactions. There was difference between groups P < 0.05, with significant statistical significance. It can be concluded that radiofrequency ablation of liver cancer is more secure. Therefore, the results of this study fully demonstrate that liver cancer treatment with noninvasive radiofrequency field-induced hyperthermia is with safety effect and satisfactory survival rate, thus with relatively high clinical value in clinical practice.

The prevalence of fibromyalgia (FM) in males is much lower than in women. Thus, current knowledge about the syndrome has been developed from research with women. The aim of the present study is to analyze whether FM manifestations differ as a function of sex. Two clinical groups with FM (21 males and 21 women) and a control group of healthy men (n= 21) participated in the study. Several aspects of pain, sleep, fatigue, psychopathology, emotional distress and functional impact of FM were evaluated with an algometer and questionnaires. The clinical groups showed a significantly greater impairment than the control group in all the self-report measures. However, the FM patients only showed significant differences in the sensibility threshold to the pain, which was lower in the women. In addition, the best predictor of the experience of pain in males was sleep quality, and in the women, catastrofying pain. Our results suggest that the most effective therapeutic strategies to control pain may be different for men and women.

Background and aims Plasma rich in growth factors (PRGF) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. The aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade II mandibular molar furcation involvement using autogenous bone graft with and without PRGF. Materials and methods In this double-blind clinical trial, thirty mandibular molars with grade II furcation involvement in 30 patients were selected. The test group received bone graft combined with PRGF, while the control group was treated with bone graft only. Clinical parameters included clinical probing depth (CPD), vertical clinical attachment level (V-CAL), horizontal clinical attachment level (H-CAL), location of gingival margin (LGM), surgically exposed horizontal probing depth of bony defect (E-HPD), vertical depth of bone crest (V-DBC), vertical depth of the base of bony defect (V-DBD), and length of the intrabony defect (LID). After six months, a re-entry surgery was performed. Data were analyzed by SPSS 14, using Kolmogorov, Mann-Whitney U, and paired t-test. Results After 6 months, both treatment methods led to significant improvement in V-CAL and H-CAL and significant decreases in CPD, E-HPD, V-DBD and LID; there was no significant difference in LGM and V-DBC in any of the treated groups compared to the baseline values. Also, none of the parameters showed significant differences between the study groups. Conclusion Although autogenous bone grafts, with or without PRGF, were successful in treating grade II furcation involvement, no differences between the study groups were observed. PMID:23486928

Encopresis is often the result of chronic constipation in the majority of paediatric patients. In clinical practice, however, encopresis is also seen without constipation and it is unknown whether these two clinical variants are based on similar or different pathophysiological mechanisms, requiring different therapeutic approaches. We analysed clinical symptoms, colonic transit time (CTT), orocaecal transit time (OCTT), anorectal manometric profiles, and behavioural scores. Patients were divided into two groups, one consisted of 111 children with paediatric constipation, and another group of 50 children with encopresis and/or soiling without constipation. Significant clinical differences in children with encopresis/soiling existed compared with children with paediatric constipation regarding: bowel movements per week, the number of daytime soiling episodes, the presence of night time soiling, the presence and number of encopresis episodes, normal stools, pain during defecation, abdominal pain, and good appetite. Total and segmental CTT were significantly prolonged in paediatric constipation compared with encopresis/soiling, 62.4 (3.6-384) and 40.2 (10.8-104.4) hours, respectively. No significant differences were found in OCTT. Among the two groups, all manometric parameters were comparable, except for a significantly higher threshold of sensation in children with paediatric constipation. The defecation dynamics were abnormal in 59% and 46% in paediatric constipation and encopresis/soiling, respectively, and were significantly different from controls. Using the child behaviour checklist no significant differences were found when comparing children with paediatric constipation and encopresis/soiling, while both patient groups differed significantly from controls. In conclusion, our findings support the concept of the existence of encopresis as a distinct entity in children with defecation disorders. Identification of such children is based on clinical symptoms, that is, normal defecation frequency, absence of abdominal or rectal palpable mass, in combination with normal marker studies and normal anal manometric threshold of sensation, Thus, encopresis is not always the result of constipation and can be the only clinical presentation of a defecation disorder.

Severity of illness, treatment choices, and clinical outcomes may vary with physician training. This study was performed to determine whether such differences exist among patients with congestive heart failure (CHF) treated by cardiologists and by noncardiologists in the community hospital setting. Prospective cohort study. Ten acute-care community hospitals. PATIENTS, MEASUREMENTS, AND RESULTS: Two thousand four hundred fifty-four patients with CHF were identified and followed up for 6 months after hospital discharge. Patients who were not treated by a cardiologist (group I; n = 977) were compared with patients whose attending physician was a cardiologist (group II; n = 419) and patients who received consultative care from a cardiologist (group III; n = 1,058). When compared with group I patients, group II patients were more likely to receive the recommended diagnostic tests and treatment strategies, although some of these differences could be explained by variations in the case mix. Group II patients had higher hospital charges, but lower CHF readmission rates and better postdischarge quality-of-life measures. No differences in adjusted mortality rates were observed. In the community-hospital setting, the clinical practices of cardiologists are more compatible with published treatment guidelines than the clinical practices of other physicians. The benefits of cardiology specialty care include lower CHF readmission rates and better postdischarge quality-of-life measures, rather than lower mortality rates, fewer hospital charges, or shorter length of stay.

Objectives Perinatal asphyxia (PA) is very significant in perinatal medicine due to the involvement of the central nervous system. This study was conducted to investigate the biochemical, clinical, and paraclinical changes associated with phenobarbital administration in neonates with PA. Methods In this prospective, case-control study, 30 neonates with PA in two groups of 15 each (case and control) were investigated. The case group received 20 mg/kg intravenous phenobarbital within six hours of birth, and the control group did not receive phenobarbital. Serum concentrations of nitric oxide (NO) were measured at enrollment and one week after birth in the two groups. Clinical, electroencephalography, and magnetic resonance imaging findings of the two groups were compared. Results At enrollment, the two groups did not differ in clinical severity, seizure incidence, or NO concentration. After one week, NO concentration was significantly lower in the case group (p < 0.050), but there was no significant difference in other variables between the two groups. Conclusions Early administration of phenobarbital in term neonates with PA could protect them against encephalopathy. PMID:27602186

Abstract To investigate the clinical features and perinatal treatment of thrombocytopenia induced by different causes during pregnancy. Clinical data from 195 pregnant women with thrombocytopenia attending 2 tertiary hospitals from January 2014 to October 2016 were retrospectively studied. The obtained data were analyzed with SPSS 19.0 software. There were 117 (60.0%), 55 (28.2%), and 23 cases (11.8%) of pregnancy-associated thrombocytopenia (PAT), idiopathic thrombocytopenia (ITP), and hypertensive disorder in pregnancy (PIH), respectively. The percentage of nulliparous women, gestational age at delivery, date of diagnosis of thrombocytopenia, and delivery mode significantly differed between the patients in these 3 groups (P < .05). Patients with PIH had a higher percentage of premature delivery and of lower birth weight infants than patients in the other 2 groups. The 3 groups had similar incidences of postpartum hemorrhage, rates of stillbirth, and neonatal Apgar scores at 5 minutes. PAT and PIH patients had different platelet counts after delivery compared with at diagnosis, whereas the platelet counts of the ITP patients were similar at diagnosis and after delivery. ITP patients in the nontreatment group and the treatment group had significantly different platelet counts (P < .05), and in the treatment group, the maternal platelet count did not differ for treatment with intravenous immunoglobulin (IVIg) versus corticosteroids. The causes of thrombocytopenia in pregnancy are diverse, and the clinical features vary widely. Timely analysis is needed to determine the primary cause of thrombocytopenia, and appropriate therapy should then be selected to effectively improve the prognosis of pregnancies. PMID:28723784

Feedback cards are recommended as a feasible tool for structured written feedback delivery in clinical education while effectiveness of this tool on the medical students' performance is still questionable.  The purpose of this study was to compare the effects of structured written feedback by cards as well as verbal feedback versus verbal feedback alone on the clinical performance of medical students at the Mini Clinical Evaluation Exercise (Mini-CEX) test in an outpatient clinic. This is a quasi-experimental study with pre- and post-test comprising four groups in two terms of medical students' externship. The students' performance was assessed through the Mini-Clinical Evaluation Exercise (Mini-CEX) as a clinical performance evaluation tool. Structured written feedbacks were given to two experimental groups by designed feedback cards as well as verbal feedback, while in the two control groups feedback was delivered verbally as a routine approach in clinical education. By consecutive sampling method, 62 externship students were enrolled in this study and seven students were excluded from the final analysis due to their absence for three days. According to the ANOVA analysis and Post Hoc Tukey test,  no statistically significant difference was observed among the four groups at the pre-test, whereas a statistically significant difference was observed between the experimental and control groups at the post-test  (F = 4.023, p =0.012). The effect size of the structured written feedbacks on clinical performance was 0.19. Structured written feedback by cards could improve the performance of medical students in a statistical sense. Further studies must be conducted in other clinical courses with longer durations.

The ability of two non-steroidal anti-inflammatory drugs to modify the clinical manifestations of pain associated with locomotor disease was assessed. Sixty-nine cats with acute or chronic locomotor disorders were recruited from 14 first opinion UK veterinary practices and randomly allocated to one of two treatment groups. Group A received meloxicam drops (0.3 mg/kg orally on day 1 followed by 0.1 mg/kg daily for four more consecutive days) and group B received ketoprofen tablets (1.0 mg/kg orally once daily for five days). Each cat underwent a full clinical examination before treatment, 24 hours after initiation of treatment and 24 hours after completion of treatment. General clinical parameters (demeanour and feed intake) and specific locomotor parameters (weightbearing, lameness, local inflammation and pain on palpation) were scored using a discontinuous scale scoring system. The two groups did not differ in terms of age, weight, gender distribution or duration of clinical signs; nor did they differ in terms of general clinical or specific locomotor scores pretreatment. Both treatment regimens resulted in a significant improvement in demeanour, feed intake and weightbearing, and a significant reduction in lameness, pain on palpation and inflammation. No significant difference was observed between the two treatment groups with respect to any of the parameters measured and both treatments were associated with minimal observed side effects. Meloxicam and ketoprofen were found to be effective analgesics and well tolerated in cats with acute or chronic locomotor disorders when administered for short-term treatment (five days) in such cases. However, meloxicam was assessed to be significantly more palatable than ketoprofen.

Few studies have examined structured rehabilitation techniques for improving activities of daily living in people with mild-moderate dementia. We sought to examine the advantages to delivering the Skill-building through Task-Oriented Motor Practice (STOMP) intervention in the home environment (versus the clinic), hypothesizing that ADL improvement would be significantly better, time to meeting goals would be faster and fewer displays of behavior would be noted. Compared results of two quasi-experimental studies of STOMP, one completed in the home, one completed previously in a clinic. Participants were English-speaking; community dwelling adults aged 50-90 diagnosed with mild-moderate dementia who could participate in an intensive rehabilitation program (5 days/week, 3 hours/day, for 2 weeks). Outcome measurements include examiner-observation of performance and proxy-report of performance and satisfaction with performance in patient-selected goals. No differences existed in the sociodemographic characteristics between the home and clinic groups where the groups were primarily white, married, had > high school education and had mild-moderate dementia. Results from the home group indicate that participants made significant improvement in ADL which was generally retained at the 90 day follow-up. These results were not significantly different than the clinic group. No significant advantages were noted for the home group in terms of time to meeting goals or exhibition of fewer behaviors. The STOMP intervention appeared to work equally as well in the home and in the clinic. Future studies should continue to examine the benefits of massed practice using high-dose regimens.

2010-11-01

Whilst preparing undergraduate students for a clinical course in paediatric dentistry, four consecutive classes (n = 107) were divided into two groups. Seven behaviour-modifying techniques were introduced: systematic desensitization, operant conditioning, modelling, Tell, Show, Do-principle, substitution, change of roles and the active involvement of the patient. The behaviour-modifying techniques that had been taught to group one (n = 57) through lecturing were taught to group two (n = 50) through video sequences and vice versa in the following semester. Immediately after the presentations, students were asked by means of a questionnaire about their perceptions of ease of using the different techniques and their intention for clinical application of each technique. After completion of the clinical course, they were asked about which behaviour-modifying techniques they had actually used when dealing with patients. Concerning the perception of ease of using the different techniques, there were considerable differences for six of the seven techniques (P < 0.05). Whilst some techniques seemed more difficult to apply clinically after lecturing, others seemed more difficult after video-based teaching. Concerning the intention for clinical application and the actual clinical application, there were higher percentages for all techniques taught after video-based teaching. However, the differences were significant only for two techniques in each case (P < 0.05). It is concluded that the use of video based teaching enhances the intention for application and the actual clinical application only for a limited number of behaviour-modifying techniques. © 2010 John Wiley & Sons A/S.

Early diagnosis through newborn screening (NBS) and early treatment of cystic fibrosis (CF) do lead to better prognosis. In the Netherlands, the median age for a clinical diagnosis is six months, and after newborn screening this is 30 days. It is unknown if being diagnosed at the age of six months or before two months leads to a clinically relevant difference of the clinical condition at the time of diagnosis. The aim of this study is to assess the differences in clinical parameters at diagnosis between children with CF identified by newborn screening (NBS) or by clinical diagnosis (CD) in the Netherlands. From July 1st, 2007 to January 1st, 2012 all newly diagnosed CF patients were reported to the Dutch Paediatric Surveillance Unit (DPSU). All paediatricians received a questionnaire to collect data on mutations and clinical condition at diagnosis. Non-classical CF was excluded from the analysis on clinical condition. 204 new CF diagnoses were reported to the DPSU, 33 were reported twice and three had no CF after further testing. 127 questionnaires were returned (76%); 85 children were diagnosed because of clinical symptoms, 40 after NBS and two because of a positive family history. The median age at diagnosis was 34 weeks for a clinical diagnosis and 3 weeks after NBS. Non-classical CF was more prevalent in the NBS group (6 clinical, 14 NBS), mostly F508del/R117H7T (12). Compared to the NBS group, significantly more patients in the CD group showed failure to thrive, respiratory symptoms, and hospitalizations. 62% of the CD group showed abnormal signs at physical examination compared to 4% of the NBS group. At the time of diagnosis infants detected after NBS are in a significantly better condition than after a clinical diagnosis. Growth retardation is already seen when after NBS the diagnosis is confirmed, but NBS leads to a diagnosis before respiratory symptoms have developed. Copyright © 2014 Elsevier Inc.

Surgical navigation in TKA facilitates better alignment; however, it is unclear whether improved alignment alters clinical evolution and midterm and long-term complication rates. We determined the alignment differences between patients with standard, manual, jig-based TKAs and patients with navigation-based TKAs, and whether any differences would modify function, implant survival, and/or complications. We retrospectively reviewed 97 patients (100 TKAs) undergoing TKAs for minimal preoperative deformities. Fifty TKAs were performed with an image-free surgical navigation system and the other 50 with a standard technique. We compared femoral angle (FA), tibial angle (TA), and femorotibial angle (FTA) and determined whether any differences altered clinical or functional scores, as measured by the Knee Society Score (KSS), or complications. Seventy-three patients (75 TKAs) had a minimum followup of 8 years (mean, 8.3 years; range, 8-9.1 years). All patients included in the surgical navigation group had a FTA between 177° and 182º. We found no differences in the KSS or implant survival between the two groups and no differences in complication rates, although more complications occurred in the standard technique group (seven compared with two in the surgical navigation group). In the midterm, we found no difference in functional and clinical scores or implant survival between TKAs performed with and without the assistance of a navigation system. Level II, therapeutic study. See the Guidelines online for a complete description of levels of evidence.

To examine the effects of high-fidelity patient simulation (HFPS) led clinical reasoning course among undergraduate nursing students. A quasi-experimental study of non-equivalent control group pretest-post test design was applied. A total of 49 senior nursing students participated in this study. The experimental group consisted of the students who took the "clinical reasoning" course (n = 23) while the control group consisted of students who did not (n = 26). Self-administered scales including the nursing core competencies, problem solving, academic self-efficacy, and Kolb learning style inventory were analyzed quantitatively using SPSS version 20.0. Data analysis was conducted using one-way ancova due to a significant difference in nursing core competencies between the experimental group and control group. There was a significant improvement in nursing core competencies in the experimental group (F = 7.747, P = 0.008). The scores of problem solving and academic self-efficacy were higher in the experimental group after the HFPS led clinical reasoning course without statistical difference. There is a need for the development of effective instructional methods to improve learning outcomes in nursing education. Future research is needed related to simulation education as well as management strategies so that learning outcomes can be achieved within different students' learning style. © 2015 The Authors.

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.

The aim of the present study was to examine the clinical merits of joint application of β-sodium aescinate and mannitol for the treatment of early swelling of upper limb trauma after surgery. We verified whether the expression of serum aquaporin 1 (AQP-1) was involved in swelling mechanism. A total of 102 patients with swelling after upper limb trauma surgery were enrolled into the study and divided randomly into 3 groups (n=34 cases per group). Group A was treated with β-sodium aescinate; group B was treated with with mannitol and group C was treated with both β-sodium aescinate and mannitol. The expression level of AQP-1, and clinical effects and complications before and after treatment were compared§. The time of swelling subsidence in group C was significantly shorter than that of the other two groups and differences were statistically significant (P<0.05). The recovery ratio and total efficiency in group C were significantly higher than those in other two groups and differences were statistically significant (P<0.05). Three and seven days after treatment, the AQP-1 levels in group A and group C were decreased and AQP-1 level decreased further with time. Differences of comparison within groups were statistically significant (P<0.05), although the differences of comparison between the groups showed no statistical significance (P>0.05). We also compared the AQP-1 level in group B before and after treatment, and the differences were not statistically significant (P>0.05). When the complication incidence in the 3 groups was compared, no statistical significance was detected (P>0.05). We concluded that the joint use of β-sodium aescinate and mannitol in treating early swelling after upper limb trauma surgery produced satisfactory outcomes. This might be related to reduction of the AQP-1 level.

To determine the effect of clinical scores that predict streptococcal infection or rapid streptococcal antigen detection tests compared with delayed antibiotic prescribing. Open adaptive pragmatic parallel group randomised controlled trial. Primary care in United Kingdom. Patients aged ≥ 3 with acute sore throat. An internet programme randomised patients to targeted antibiotic use according to: delayed antibiotics (the comparator group for analyses), clinical score, or antigen test used according to clinical score. During the trial a preliminary streptococcal score (score 1, n=1129) was replaced by a more consistent score (score 2, n=631; features: fever during previous 24 hours; purulence; attends rapidly (within three days after onset of symptoms); inflamed tonsils; no cough/coryza (acronym FeverPAIN). Symptom severity reported by patients on a 7 point Likert scale (mean severity of sore throat/difficulty swallowing for days two to four after the consultation (primary outcome)), duration of symptoms, use of antibiotics. For score 1 there were no significant differences between groups. For score 2, symptom severity was documented in 80% (168/207 (81%) in delayed antibiotics group; 168/211 (80%) in clinical score group; 166/213 (78%) in antigen test group). Reported severity of symptoms was lower in the clinical score group (-0.33, 95% confidence interval -0.64 to -0.02; P=0.04), equivalent to one in three rating sore throat a slight versus moderate problem, with a similar reduction for the antigen test group (-0.30, -0.61 to -0.00; P=0.05). Symptoms rated moderately bad or worse resolved significantly faster in the clinical score group (hazard ratio 1.30, 95% confidence interval 1.03 to 1.63) but not the antigen test group (1.11, 0.88 to 1.40). In the delayed antibiotics group, 75/164 (46%) used antibiotics. Use of antibiotics in the clinical score group (60/161) was 29% lower (adjusted risk ratio 0.71, 95% confidence interval 0.50 to 0.95; P=0.02) and in the antigen test group (58/164) was 27% lower (0.73, 0.52 to 0.98; P=0.03). There were no significant differences in complications or reconsultations. Targeted use of antibiotics for acute sore throat with a clinical score improves reported symptoms and reduces antibiotic use. Antigen tests used according to a clinical score provide similar benefits but with no clear advantages over a clinical score alone. ISRCTN32027234.

There has been a recent interest in the double row repair method for arthroscopic rotator cuff repair following favourable biomechanical results reported by some studies. The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears. 22 patients of arthroscopic single row repair (group I) and 25 patients who underwent double row repair (group II) from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES). In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method. Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

Objectives: To investigate the clinical, pathological, and sonographic characteristics of unexpected gallbladder carcinoma (UGC). Methods: Of 5424 patients who had undergone cholecystectomy from December 2006 to October 2013, 54 patients with primary gallbladder carcinomas confirmed by pathological diagnosis were identified. The patients were divided into two groups: diagnosed before operation (n=34) and UGC groups (n=20), of whom the clinical, pathological, and sonographic characteristics were compared. Results: No significant differences in age, gender, location of lesion, histological type, length of the gallbladder, existence of biliary sludge, and intestinal gas interference between the two groups were found (all P>0.05). The clinical symptoms, laboratory abnormalities, tumor markers, coexisting gallbladder stones, lesion size, lesion type, degree of differentiation, and tumor staging showed statistically significant differences between the two groups (all P<0.05). On ultrasound, the width of the gallbladder, gallbladder wall thickness, vascularity on color Doppler ultrasound, and bile volume in the gallbladder showed significant differences (all P<0.05). Conclusions: UGCs are commonly found at an early stage, often well-differentiated, wall thickened, and are generally accompanied with cholelithiasis. UGCs should be taken into consideration in cases with cholelithiasis or small gallbladder on ultrasound. PMID:26379911

Single-fiber electromyography (SFEMG) abnormality in the extensor digitorum communis (EDC) was reported in ocular myasthenia gravis (OMG), which indicated subclinical involvement beyond extraocular muscles in OMG patients. The relationship between the abnormal findings of SFEMG in EDC and the probability for OMG to develop generalized myasthenia gravis (GMG) is unknown. This retrospective study aimed to determine the predictive value of abnormality of SFEMG in EDC of OMG patients. One-hundred and two OMG patients underwent standard clinical diagnosis process and SFEMG test in EDC muscle when diagnosed and were clinically followed up for 5 years. The SFEMG data were compared between different clinical groups according to thymus status, onset age, and different outcome of OMG developing. Chances of progressing to GMG were compared between two different groups according to SFEMG and repetitive nerve stimulation (RNS) results, acetylcholine receptor antibody (AchRAb) titer, thymus status, and onset age. Abnormal SFEMG results were observed in 84 (82.4%) patients. The mean jitter, percentage of jitter >55 μs (%), and blocking were higher in OMG patients than in healthy volunteers. There were no statistical differences in jitter analysis between thymoma group and non-thymoma group (P = 0.65), or between the later OMG group and the later GMG group (P = 0.31), including mean jitter, percentage of jitter >55 μs (%), and blocking. Elderly group (≥45 years old) had a higher mean jitter than younger group (t = 2.235, P = 0.028). Total 55 OMG developed GMG, including 47 in abnormal SFEMG group while 8 in normal SFEMG group. There was no statistical difference in the conversion rates between the two groups (χ2 = 0.790, P = 0.140). RNS abnormality, AchRab titer, or onset age had no correlation with OMG prognosis (P = 0.150, 0.070, 0.120, respectively) while thymoma did (χ2 = 0.510, P = 0.020). SFEMG test in the EDC showed high abnormality in OMG, suggesting subclinical involvement other than extraocular muscles. Nevertheless, the abnormal jitter analysis did not predict the prognosis of OMG according to clinical follow-up.

Coronary artery diseases (CAD) are associated with psychological problems such as anxiety and depression in patients. Thus, management of these problems can consider as an important intervention by health care workers, especially nurses. The purpose of this study was to investigate the effectiveness of patient-focused clinical pathway on anxiety, depression and satisfaction of patients with CAD. In this quasi-experimental study, 138 patients suffering from CAD in a coronary care unit of a referral teaching hospital affiliated to Semnan University of Medical Sciences in Semnan, Iran, were recruited using a convenience sampling method. The participants were assigned to two groups: Clinical pathway (CP) and routine (RUT) care. The level of anxiety and depression of patients were measured in admission and discharge in both groups. Also, the level of patients' satisfaction was measured at the time of discharge. Data were analyzed using descriptive and inferential statistics. Prevalence rates of anxiety and depression in total of patients were 7.2% and 8.7%, respectively. In terms of anxiety, the mean of difference between pretest and posttest scores in the CP group (0.52 ± 1.39) was higher compared to the RUT group (-0.17 ± 1.69) and there was a significant difference between the two group (P = 0.009). In terms of depression, the mean of this difference in the CP group (0.75 ± 2.05) was higher compared to the RUT group (0.00 ± 1.08), as there was a significant difference between the two group (P = 0.024). Also, the mean of patients' satisfaction scores in the CP group (3.69 ± 0.39) was higher compared to the RUT group (3.45 ± 0.47) and there was a significant difference between the two groups (P = 0.002). According to the positive effects of CP on patients with CADs, it can be considered as a useful, safe and simple instrument for the improvement of patients' outcomes. Thus, the findings of this study can provide a new insight in patient care for clinical nurses.

Ethnicity has been associated with clinical and experimental pain responses. Whereas ethnic disparities in pain in other minority groups compared with whites are well described, pain in Asian Americans remains poorly understood. The purpose of this study was to characterize differences in clinical pain intensity and experimental pain sensitivity among older Asian American and non-Hispanic white (NHW) participants with knee osteoarthritis (OA). Data were collected from 50 Asian Americans ages 45 to 85 (28 Korean, 9 Chinese, 7 Japanese, 5 Filipino, and 1 Indian) and compared with 50 age-matched and sex-matched NHW individuals with symptomatic knee OA pain. The Western Ontario and McMaster Universities Osteoarthritis Index and Graded Chronic Pain Scale were used to assess the intensity of clinical knee pain. In addition, quantitative sensory testing was used to measure experimental sensitivity to heat-induced and mechanically induced pain. Asian American participants had significantly higher levels of clinical pain intensity than NHW participants with knee OA. In addition, Asian American participants had significantly higher experimental pain sensitivity than NHW participants with knee OA. These findings add to the growing literature regarding ethnic and racial differences in clinical pain intensity and experimental pain sensitivity. Asian Americans in particular may be at risk for clinical pain and heightened experimental pain sensitivity. Further investigation is needed to identify the mechanisms underlying ethnic group differences in pain between Asian Americans and NHWs, and to ensure that ethnic group disparities in pain are ameliorated.

Long-term outcomes after sirolimus-eluting stent (SES) implantation in haemodialysis (HD) patients have remained controversial. We investigated the impact of HD on outcomes after SES implantation. We analysed the data on 2050 patients who underwent SES implantation in a multi-centre prospective registry in Japan. Three-year clinical outcomes were compared between the HD group (n = 106) and the non-haemodialysis (NH) group (n = 1944). At the 3-year clinical follow-up, the rates of unadjusted cardiac mortality (HD: 16.3 vs. NH: 2.3%) and target-lesion revascularization (TLR) (HD: 19.4 vs. NH: 6.6%) were significantly higher in the HD group than the NH group (P < 0.001). Although HD group had a numerically higher stent thrombosis rate, the difference in stent thrombosis between the two groups (HD: 2.0 vs. NH: 0.7%) did not reach statistical significance. Using Cox's proportional-hazard models with propensity score adjustment for baseline differences, the HD group had higher risks of TLR [HD: 16.3 vs. NH: 6.1%; hazard ratio, 2.83; 95% confidence interval (CI): 1.62-4.93, P = 0.0003] and cardiac death (HD: 12.3 vs. NH: 2.3%; hazard ratio, 5.51; 95% CI: 2.58-11.78, P < 0.0001). The consistent results of analyses, whether unadjusted or adjusted for other baseline clinical and procedural differences, identify HD as an independent risk factor for cardiac death and TLR. Percutaneous coronary intervention with SES in HD patients has a higher incidence of repeat revascularization and mortality compared with those in NH patients. Haemodialysis appears to be strongly associated with mortality and repeat revascularization even after SES implantation.

Cervical disc arthroplasty (CDA) with Discover prosthesis or anterior cervical discectomy and fusion (ACDF) with Zero-P cage has been widely used in the treatment of cervical spondylotic myelopathy (CSM). However, little is known about the comparison of the 2 zero-profile implants in the treatment of single-level CSM. The aim was to compare the clinical outcomes and radiographic parameters of CDA with Discover prosthesis and ACDF with Zero-P cage for the treatment of single-level CSM. A total of 128 consecutive patients who underwent 1-level CDA with Discover prosthesis or ACDF with Zero-P cage for single-level CSM between September 2009 and December 2012 were included in this study. Clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score and Neck Disability Index (NDI). For radiographic assessment, the overall sagittal alignment (OSA), functional spinal unit (FSU) angle, and range of motion (ROM) at the index and adjacent levels were measured before and after surgery. Additionally, the complications were also recorded. Both treatments significantly improved all clinical parameters (P < 0.05), without statistically relevant differences between the 2 groups. The OSA and FSU angle increased significantly in both groups (P <0.05). Compared with Zero-P group, ROMs at the index levels were well maintained in the Discover group (P < 0.05). However, there were no statistical differences in the ROMs of adjacent levels between the 2 groups (P > 0.05). Besides, no significant differences existed in dysphagia, subsidence, or adjacent disc degeneration between the 2 groups (P > 0.05). However, significant differences occurred in prosthesis migration in CDA group. The results of this study showed that clinical outcomes and radiographic parameters were satisfactory and comparable with the 2 techniques. However, more attention to prosthesis migration of artificial cervical disc should be paid in the postoperative early-term follow-up.

Little is known about the epidemiology of urogenital Chlamydia trachomatis infection (chlamydia) in Suriname. Suriname is a society composed of many ethnic groups, such as Creoles, Maroons, Hindustani, Javanese, Chinese, Caucasians, and indigenous Amerindians. We estimated determinants for chlamydia, including the role of ethnicity, and identified transmission patterns and ethnic sexual networks among clients of two clinics in Paramaribo, Suriname. Participants were recruited at two sites a sexually transmitted infections (STI) clinic and a family planning (FP) clinic in Paramaribo. Urine samples from men and nurse-collected vaginal swabs were obtained for nucleic acid amplification testing. Logistic regression analysis was used to identify determinants of chlamydia. Multilocus sequence typing (MLST) was performed to genotype C. trachomatis. To identify transmission patterns and sexual networks, a minimum spanning tree was created, using full MLST profiles. Clusters in the minimum spanning tree were compared for ethnic composition. Between March 2008 and July 2010, 415 men and 274 women were included at the STI clinic and 819 women at the FP clinic. Overall chlamydia prevalence was 15% (224/1508). Age, ethnicity, and recruitment site were significantly associated with chlamydia in multivariable analysis. Participants of Creole and Javanese ethnicity were more frequently infected with urogenital chlamydia. Although sexual mixing with other ethnic groups did differ significantly per ethnicity, this mixing was not independently significantly associated with chlamydia. We typed 170 C. trachomatis-positive samples (76%) and identified three large C. trachomatis clusters. Although the proportion from various ethnic groups differed significantly between the clusters (P = 0.003), all five major ethnic groups were represented in all three clusters. Chlamydia prevalence in Suriname is high and targeted prevention measures are required. Although ethnic sexual mixing differed between ethnic groups, differences in prevalence between ethnic groups could not be explained by sexual mixing.

To study the clinical effect of Gelatamp colloidal silver gelatin sponge on preventing the complication of teeth extraction. 672 teeth were divided into experimental group and control group semi-randomly. All teeth were extracted after local anesthesia and sockets were cleaned. Gelatamp colloidal silver gelatin sponge was implanted into socket in experimental group and nothing was implanted into alveolar socket in control group. The complication of teeth extraction was observed on 0.5 h, 2 d and 7 d after extraction. The incidence rate of complication was calculated. The incidence rate of complication of teeth extraction in experimental group was 7.72%, which was lower than that of control group (24.43%). There was significant difference in the incidence rates of complication between experimental group and control group (P < 0.05). The incidence rate of bleeding, infection, pain, swelling and dry socket after teeth extraction in experimental group was lower than those of control group, and the difference between them was statistically significant (P < 0.05). The results demonstrate that Gelatamp colloidal silver gelatin sponge can prevent the occurrence of complication of teeth extraction, this can be used in clinic.

To determine whether military health care beneficiaries with low back pain (LBP) who are likely to respond successfully to spinal manipulation experience a difference in short-term clinical outcomes based on the manipulation technique that is used. Sixty patients with LBP identified as likely responders to manipulation underwent a standardized clinical examination and were randomized to receive a lumbopelvic (LP) or lumbar neutral gap (NG) manipulation technique. Outcome measures were a numeric pain rating scale and the modified Oswestry Disability Questionnaire. Both the LP and NG groups experienced statistically significant reductions in pain and disability at 48 hours postmanipulation. The improvements seen in each group were small because of the short follow-up. There were no statistically significant or clinically meaningful differences in pain or disability between the two groups. The two manipulation techniques used in this study were equally effective at reducing pain and disability when compared at 48 hours posttreatment. Clinicians may employ either technique for the treatment of LBP and can expect similar outcomes in those who satisfy the clinical prediction rule (CPR). Further research is required to determine whether differences exist at longer-term follow-up periods, after multiple treatment sessions, or in different clinical populations.

Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p < 0.0001). Combined and nighttime reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p < 0.05). There was no difference in Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory scores among three groups. GERD patients with combined daytime and nighttime reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

To investigate the clinical characteristics of Leber hereditary optic neurology (LHON) patients with different primary site mutation. Four hundred and fourteen patients with optic neuropathy were divided into three groups: clinically diagnosed LHON group (group A), probable LHON group (group B), optic neuropathy of unknown reason group (group C). Visual acuity (VA), colour vision, Intraocular pressure (IOP), virtual field and visual evoked potential (VEP) were tested for all the patients. Some (64 cases) had optical coherence tomography (OCT) measurement. Mutations of mtDNA were detected for all the groups, and clinical analysis were carried out emphatically in the patients with the 11778 mutation confirmed by gene assessment. T paired test was used to evaluate two group patients of different Mitochondrial DNA mutation. Gene mutations were found in 215 of the 414 patients (52%). Approximately 93% (199/255) of the patients were caused by the common primary mutations (11778, 14484, 3460 mutation), in which 100% mutation (106/106) in group A, 65% (91/139) in group B, and 11% (18/169) in group C. No cases were diagnosed with confirmed LHON in the patients with unilateral optic neuropathy. Fundus examination in 334 eyes of 167 cases showed pseudo papilledema (54 eyes), normal (67 eyes), pale disc or pale on the temporal side of the optic disc (213 eyes). On the basis data of OCT from 64 patients and 84 normal person, RNFL was found thickening at the early stage and thinning gradually at the later stage in the LHON patients. But, the RNFL thickness of patients with 1-2 years history was not significantly different from the patients with over 2 years history(P = 0.051), and there was no difference among the patients with different mitochondrial DNA mutations. The initial mean VA of patients with the 14484 mutation and 11778 mutation were 3.6 ± 0.65, 3.75 ± 0.54 (t = 0.536, P > 0.05), but the follow-up VA were 4.29 ± 0.55 (t = 4.034, P < 0.001) and 3.93 ± 0.49 respectively (t = 1.857, P > 0.05). The symptoms and fundus manifestation were similar in the LHOH patients with different primary site mutation. Gene mutation analysis is helpful to assess the prognosis of visual acuity.

The serotoninergic system as a target for add-on treatment seems to be a promising approach in patients with schizophrenia. To clarify if selective 5HT-6 antagonist AVN-211 (CD-008-0173) adds clinical and cognitive effects to stable antipsychotic treatment. A randomized, double-blind, placebo-controlled, add-on, 4r-week trial in 47 schizophrenia patients (21 patients receiving study drug and 26 receiving placebo) who were stabilized on antipsychotic medication was performed. Seventeen patients from the study drug group and 25 patients from the placebo group completed the trial. Treatment effects were measured using clinical rating scales and attention tests. With no differences at baseline, there was a significant difference between the groups in Positive and Negative Syndrome Scale (PANSS) positive subscale score (p = 0.058) in favor of patients in the treatment group at the endpoint. The PANSS positive subscore (p = 0.0068) and Clinical Global Impression-Severity (CGI-S) (p = 0.048) score significantly changed only in the treatment group. Only in the placebo group were significant changes in Calgary Depression Rating Scale (CDRS) total score registered. The indices of attention tests at endpoint did not show differences between the groups, with the exception of the scope of change in the results of the subtest VIII of the Wechsler Adult Intelligence Scale (WAIS), which showed difference between the groups (p = 0.02) and was significantly larger in the treatment group. Only inside the study drug group, significant changes in selectivity and continuous attention were observed regarding total correct responses (p = 0.0038) and reaction time (p = 0.058) in the Continuous Attention Task (CAT) test. Selective 5HT6 antagonist AVN-211 (CD-008-0173) added antipsychotic and some procognitive (attention) effects to antipsychotic medication.

To assess predictors of positive oral food challenge test (OFC) in neonates that are suggestive of gastrointestinal food allergy. A prospective case accumulations study on neonates suspected of having gastrointestinal food allergy was conducted in 126 neonatal intensive care units in Japan between April 2010 and September 2011. Neonates who underwent an OFC for the diagnosis of gastrointestinal food allergy were enrolled. Clinical backgrounds, clinical symptoms, and laboratory findings were compared between neonates with a positive OFC and those with a negative OFC. An analysis was performed in 32 neonates. The OFC results were positive in 9 neonates (28.1%), pseudo-positive in 4, and negative in 19. There were no significant differences in clinical backgrounds between the positive OFC group and the negative OFC group. Vomiting and bloody stool were frequently observed in both groups (approximately 70%), although there were no significant differences in the clinical symptoms between the two groups. Additional diagnostic tests included those for eosinophils in the peripheral blood and stool mucus and allergen-specific lymphocyte stimulation test. There were no significant differences in laboratory findings between the two groups, and many neonates showed pseudo-positive in all of the tests. It was difficult to predict OFC results based on clinical symptoms and additional diagnostic test results. In order to obtain an accurate diagnosis of gastrointestinal food allergy in neonates, OFC should be performed proactively under conditions that enable complete understanding of risks to neonates.

Objective The diagnosis of schizoaffective disorder has long maintained an uncertain status in psychiatric nosology. Studies comparing clinical and biological features of patients with schizoaffective disorder to patients with related disorders [e.g., schizophrenia and bipolar disorder] can provide an evidence base for judging the validity of the diagnostic category. However, because most prior studies of schizoaffective disorder have only evaluated differences between groups at a static timepoint, it is unclear how these disorders may be related when the entire illness course is taken into consideration. Methods We ascertained a large cohort [N = 993] of psychiatric patients with a range of psychotic diagnoses including schizophrenia with no history of major affective episodes [SZ−; N = 371], schizophrenia with a superimposed mood syndrome [SZ+; N = 224], schizoaffective disorder [SAD; N = 129] and bipolar I disorder with psychotic features [BPD+; N = 269]. Using cross-sectional data we designed key clinical and neurocognitive dependent measures that allowed us to test longitudinal hypotheses about the differences between these diagnostic entities. Results Large differences between diagnostic groups on several demographic and clinical variables were observed. Most notably, groups differed on a putative measure of cognitive decline. Specifically, the SAD group demonstrated significantly greater post-onset cognitive decline compared to the BP+ group, with the SZ− and SZ+ group both exhibiting levels of decline intermediate to BPD+ and SAD. Conclusions These results suggest that schizoaffective disorder may possess distinct features. Contrary to earlier formulations, schizoaffective disorder may be a more severe form of illness.

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.

To determine if the Mayo-Portland Adaptability Inventory (MPAI) demonstrates clinical utility in differentiating between persons with severe TBI and frontal lobe damage/anosognosia and persons with mild TBI and no frontal lobe damage. Forty-three persons with TBI and documented frontal lobe damage (mean age = 34; mean time since injury = 5.2 years) and 69 persons with mild TBI and no frontal lobe damage (mean age = 34.3; mean time since injury = 4.8 4.8 years). MPAI. Total inventory and select sub-category difference scores were significantly greater in the frontal lobe group than in the non-frontal lobe group. However, as expected, there was no significant difference between the two groups on the mobility sub-category difference scores. The MPAI appears to be potentially clinically useful in assessing for frontal lobe damage and associated anosognosia in patients with TBI.

Hyaluronic acid (HA) has a number of clinical applications in current practice. Therefore, correlation of HA with free radicals and inflammatory cells is clinically important. The purpose of this study is to measure the efficacy of high molecular weight HA on the oxidative stress of oral wounds (glutathione (GSH) and lipid peroxidation (LPO) levels), the inflammatory reaction (leucocytes, collagen and angiogenesis content), pain (visual analogue scale (VAS) records) and trismus (maximum interincisal opening (MIO) records) after third molar (M3) extraction. 40 patients were included in this study. 0.2 ml 0.8% HA was applied immediately after surgery within the HA group (n = 20). Nothing was applied to the control group (n = 20). The primary outcome variables were the changes in the inflammatory reaction (leucocyte, angiogenesis and collagen content), oxidative stress (GSH, LPO) and clinical parameters (VAS, MIO). Results were compared immediately after extraction (T0) and 1 week after surgery (T1). Bivariate analyses were used to assess the differences between the HA and control groups for each study variable. There was a statistically significant difference of leucocyte infiltration and angiogenesis between the groups at T1. The HA group showed less leucocyte infiltration and more angiogenesis than the control group. There was no statistically significant difference in oxidative stress, VAS or MIO levels between the groups. Our results confirm the hypothesis that HA has an anti-inflammatory effect following M3 extraction. However, the oxidative stress levels and clinical outcomes were similar after one week. Further studies examining these parameters at different times are necessary. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

This study describes the susceptibility of different fish gender following acute Streptococcus agalactiae infection by using Javanese medaka Oryzias javanicus as test fish. The fish were grouped into four groups, which were: (1) all-male; (2) all-female; (3) mixed-gender (1 male: 1 female ratio); and (4) control non-infected (1 male: 1 female ratio). The fish in group 1, 2 and 3 were intraperitoneally exposed to 5.4 × 10 8  CFU/ml of S. agalactiae, while for group 4, the fish were exposed using sterile broth. The main clinical signs and histopathological changes of infected Javanese medaka were commonly observed in S. agalactiae infected fishes. However, no difference on clinical signs and histopathological changes of fish in group 1, 2 and 3 were noticed. The Javanese medaka mortality in group 1, 2 and 3 were observed from 4 h post infection (hpi) to 6 hpi, with the cumulative mortality from 3% to 30%. Then, the mortality increased at 12 hpi, with the range from 53% to 80%. However, 100% of the infected fish dead at 24 hpi. No clinical signs, histopathological changes and fish mortality recorded in group 4. Generally, the clinical signs, mortality patterns, cumulative mortality and histopathological changes of Javanese medaka infected by S. agalactiae did not show any difference between the all-male, all-female and mixed-gender groups. This indicates that the susceptibility of fish to S. agalactiae infection is not influenced by their gender. Copyright © 2017. Published by Elsevier Ltd.

Metabolic syndrome (MetS) increases the risk of morbidity and mortality from cardiovascular disease, and exercise training is an important factor in the treatment and prevention of the clinical components of MetS. The aim was to compare the effects of high-intensity interval training and steady-state moderate-intensity training on clinical components of MetS in healthy physically inactive adults. Twenty adults were randomly allocated to receive either moderate-intensity continuous training [MCT group; 60-80% heart rate reserve (HRR)] or high-intensity interval training (HIT group; 4 × 4 min at 85-95% peak HRR interspersed with 4 min of active rest at 65% peak HRR). We used the revised International Diabetes Federation criteria for MetS. A MetS Z-score was calculated for each individual and each component of the MetS. In intent-to-treat analyses, the changes in MetS Z-score were 1.546 (1.575) in the MCT group and -1.249 (1.629) in the HIT group (between-groups difference, P =  0.001). The average number of cardiometabolic risk factors changed in the MCT group (-0.133, P = 0.040) but not in the HIT group (0.018, P = 0.294), with no difference between groups (P = 0.277). Among apparently healthy physically inactive adults, HIT and MCT offer similar cardiometabolic protection against single MetS risk factors but differ in their effect on average risk factors per subject.

The aim of this study was to assess the feasibility of Er: YAG laser in bone cutting for removal of impacted lower third molar teeth and compare its outcomes with that of surgical bur. The study comprised 40 subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters like pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing and complications were compared for both groups. Clinical parameters like pain, bleeding and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered as an alternative tool to surgical bur, specially in anxious patients.

To compare skills acquired by undergraduate nursing students enrolled in a medical-surgical course. To compare skills demonstrated by students with no previous clinical practice (undergraduates) and nurses with clinical experience enrolled in continuing professional education (CPE). In a nonrandomized clinical trial, 101 undergraduates enrolled in the "Adult Patients 1" course were assigned to the traditional lecture and discussion (n = 66) or lecture and discussion plus case-based learning (n = 35) arm of the study; 59 CPE nurses constituted a comparison group to assess the effects of previous clinical experience on learning outcomes. Scores on an objective structured clinical examination (OSCE), using a human patient simulator and cases validated by the National League for Nursing, were compared for the undergraduate control and intervention groups, and for CPE nurses (Student's t test). Controls scored lower than the intervention group on patient assessment (6.3 ± 2.3 vs 7.5 ± 1.4, p = .04, mean difference, -1.2 [95% confidence interval (CI) -2.4 to -0.03]) but the intervention group did not differ from CPE nurses (7.5 ± 1.4 vs 8.8 ± 1.5, p = .06, mean difference, -1.3 [95% CI -2.6 to 0.04]). The CPE nurses committed more "rules-based errors" than did undergraduates, specifically patient identifications (77.2% vs 55%, p = .7) and checking allergies before administering medication (68.2% vs 60%, p = .1). The intervention group developed better patient assessment skills than the control group. Case-based learning helps to standardize the process, which can contribute to quality and consistency in practice: It is essential to correctly identify a problem in order to treat it. Clinical experience of CPE nurses was not associated with better adherence to safety protocols. Case-based learning improves the patient assessment skills of undergraduate nursing students, thereby preparing them for clinical practice. © 2014 Sigma Theta Tau International.

OBJECT Unruptured posterior communicating artery (PCoA) aneurysms with oculomotor nerve palsy (ONP) have a very high risk of rupture. This study investigated the hemodynamic and morphological characteristics of intracranial aneurysms with high rupture risk by analyzing PCoA aneurysms with ONP. METHODS Fourteen unruptured PCoA aneurysms with ONP, 33 ruptured PCoA aneurysms, and 21 asymptomatic unruptured PCoA aneurysms were included in this study. The clinical, morphological, and hemodynamic characteristics were compared among the different groups. RESULTS The clinical characteristics did not differ among the 3 groups (p > 0.05), whereas the morphological and hemodynamic analyses showed that size, aspect ratio, size ratio, undulation index, nonsphericity index, ellipticity index, normalized wall shear stress (WSS), and percentage of low WSS area differed significantly (p < 0.05) among the 3 groups. Furthermore, multiple comparisons revealed that these parameters differed significantly between the ONP group and the asymptomatic unruptured group and between the ruptured group and the asymptomatic unruptured group, except for size, which differed significantly only between the ONP group and the asymptomatic unruptured group (p = 0.0005). No morphological or hemodynamic parameters differed between the ONP group and the ruptured group. CONCLUSIONS Unruptured PCoA aneurysms with ONP demonstrated a distinctive morphological-hemodynamic pattern that was significantly different compared with asymptomatic unruptured PCoA aneurysms and was similar to ruptured PCoA aneurysms. The larger size, more irregular shape, and lower WSS might be related to the high rupture risk of PCoA aneurysms.

To identify the clinical features of gastric mucosa-associated lymphoid tissue (MALT) lymphoma with extra copies of MALT1. This is a multi-centered, retrospective study. We reviewed 146 patients with MALT lymphoma in the stomach who underwent fluorescence in situ hybridization analysis for t(11;18) translocation. Patients were subdivided into patients without t(11;18) translocation or extra copies of MALT1 (Group A, n = 88), patients with t(11;18) translocation (Group B, n = 27), and patients with extra copies of MALT1 (Group C, n = 31). The clinical background, treatment, and outcomes of each group were investigated. Groups A and C showed slight female predominance, whereas Group B showed slight male predominance. Mean ages and clinical stages at lymphoma diagnosis were not different between groups. Complete response was obtained in 61 patients in Group A (69.3%), 22 in Group B (81.5%), and 21 in Group C (67.7%). Helicobacter pylori (H. pylori) eradication alone resulted in complete remission in 44 patients in Group A and 13 in Group C. In Group B, 14 patients underwent radiotherapy alone, which resulted in lymphoma disappearance. Although the difference was not statistically significant, event-free survival in Group C tended to be inferior to that in Group A (P = 0.10). Patients with t(11;18) translocation should be treated differently from others. Patients with extra copies of MALT1 could be initially treated with H. pylori eradication, similar to patients without t(11;18) translocation or extra copies of MALT1.

Minimally invasive techniques have broadened the horizons of periodontal plastic surgery to improve treatment outcomes. Thus, the purpose of this clinical trial was to compare root coverage, postoperative morbidity, and esthetic outcomes of subepithelial connective tissue graft (SCTG) technique with or without the use of a surgical microscope in the treatment of gingival recessions. In this split-mouth study, twenty-four patients with bilateral Miller's Class I or II buccal gingival recessions ≥2.0 mm in canines or premolars were selected. Gingival recessions were randomly designated to receive treatment with SCTG with or without the assistance of the surgical microscope (test and control groups, respectively). Clinical parameters evaluated included the following: depth (RH) and width (RW) of the gingival defect, width (WKT) and thickness (TKT) of keratinized tissue, probing depth (PD), and clinical attachment level (CAL). Postoperative morbidity was evaluated by means of an analog visual scale and questionnaire. Patient satisfaction was also evaluated with a questionnaire. Descriptive statistics were expressed as mean ± SD. Repeated-measures analysis of variance was used for examination of differences regarding PD, CAL, and TKT. The Wilcoxon test was used to detect differences between groups and the Friedman test to detect differences within group regarding WKT, RH, and RW. The average percentages of root coverage for test and control treatments, after 12 months, were 98.0% and 88.3%, respectively (P <0.05). Complete root coverage was achieved in 87.5% and 58.3% of teeth treated in test and control groups, respectively. For all parameters except recession height, there was an improvement in the final examination but without difference between treatments. For the RH, a lower value was found in the test group compared to the control group (P <0.05). In the test group, all patients were satisfied with the esthetics obtained, and 19 patients (79.1%) were satisfied in the control group. For postoperative morbidity, 14 patients in each of the two treatment groups did not use analgesics for pain control. Both approaches were capable of producing root coverage; however, use of the surgical microscope was associated with additional clinical benefits in the treatment of teeth with gingival recessions.

Abstract This study investigated clinical outcomes of biomimetic mineralized collagen artificial bone putty for bone reconstruction in the treatment of calcaneus fracture. Sixty cases of calcaneal fractures surgically treated with open reduction and internal fixation in our hospital from June 2014–2015 were chosen and randomly divided into two groups, including 30 cases treated with biomimetic mineralized collagen artificial bone putty as treatment group, and 30 cases treated with autogenous ilia as control group. The average follow-up time was 17.2 ± 3.0 months. The results showed that the surgery duration and postoperative drainage volume of treatment group were significantly lower than control group; there were no statistically significant differences in the fracture healing time, American Orthopaedic Foot and Ankle Society scores at 3 and 12 months after surgery, Böhler’s angle, Gissane’s angle and height of calcaneus between the two groups. There were no significant differences in wound complication and reject reaction between the two groups, while significant difference in donor site complication. As a conclusion, the implantation of biomimetic mineralized collagen artificial bone putty in the open reduction of calcaneal fracture resulted in reliable effect and less complications, which is suitable for clinical applications in the treatment of bone defect in calcaneal fractures.

A high prevalence of cholestatic disease, including gallbladder mucocele (GBM), has been reported in dogs with naturally occurring pituitary-dependent hyperadrenocorticism (PDH). Differences exist in the clinical features of dogs with PDH and concurrent cholestatic disease, and also is the management of these dogs with trilostane. Sixty-five client-owned dogs with naturally occurring PDH. This was a retrospective, observational case series. Each dog was treated with trilostane for at least 3 months before the study, and had a good clinical response, as determined by owners. Statistical comparisons of clinical signs, results of routine blood tests, basal and post-ACTH cortisol concentration, and optimal trilostane dosage were made after dogs were separated into the following 3 groups by ultrasonographic imaging: normal on ultrasound (NOU) group, cholestasis group, and GBM group. The GBM group had more severe clinical signs and significantly different total serum cholesterol concentration and post-ACTH stimulation cortisol concentration at the time of diagnosis. Dogs that weighed <6 kg had a significantly higher prevalence of cholestatic disease than did the other dogs (P = .003). The optimal trilostane dosages for the GBM and cholestasis groups were 2.5 and 1.5 times the dosage of the NOU group, respectively (P < .001). Gallbladder disease associated with cholestatic disease is correlated with PDH in dogs, in both its clinical features and drug management. These findings may be associated with hypercholesterolemia, unidentified genetic factors, and the hydrophobic nature of trilostane. Copyright © 2017 The Authors.

The serum Krebs von der Lungen-6 (KL-6) level is a useful marker correlated with the severity of various interstitial lung diseases. There have been few reports about the clinical characteristics of organizing pneumonia (OP) associated with the serum KL-6 levels. This study was performed to determine whether the serum KL-6 levels can help determine the optimal treatment for OP. Patients diagnosed with OP by clinical, radiological and histopathological findings were retrospectively reviewed. The OP patients were classified into two groups based on their serum KL-6 levels: normal KL-6 and high KL-6 groups. The two groups were compared with regard to their clinical and radiological data and therapeutic response one month after the start of treatment. The clinical records of twenty-two patients diagnosed with OP were reviewed. The serum KL-6 level was elevated in 11 of the 22 patients. There were no obvious differences in the clinical data between the two groups, although patients in the normal KL-6 group tended to have a fever. There were no significant differences in the chest X-ray (CXR) score or computed tomography (CT) score between the two groups. The CXR scores were correlated with the serum KL-6 levels. At 1 month after the diagnosis, 11 patients who needed treatment with prednisolone were included in the high KL-6 group. Patients with normal KL-6 levels showed lower CXR and CT scores. The serum KL-6 level on admission is a useful marker to judge the need for corticosteroid treatment in OP patients.

This study aims to investigate the clinical efficacy of Dextran 40 plus dexamethasone on the prevention of fat embolism syndrome (FES) in high-risk patients with long bone shaft fractures. According to the different preventive medication, a total of 1837 cases of long bone shaft fracture patients with injury severity score (ISS) > 16 were divided into four groups: dextran plus dexamethasone group, dextran group, dexamethasone group and control group. The morbidity and mortality of FES in each group were analyzed with pairwise comparison analysis. There were totally 17 cases of FES and 1 case died. The morbidity of FES was 0.33% in dextran plus dexamethasone group and significantly lowers than that of other groups (P < 0.05). There was no significant difference among other groups (P > 0.05). Conclusion from our data is dextran 40 plus dexamethasone can effectively prevent long bone shaft fractures occurring in high-risk patients with FES.

To determine the clinical efficacy of posterior intervertebral surgery for single-segment thoracolumbar spinal tuberculosis.
 Methods: Clinical data were retrospectively analyzed in 62 patients with thoracolumbar spinal tuberculosis who underwent posterior intervertebral surgery (A group) or posterior and anterior combined intervertebral surgery (B group) from January 2010 to January 2015 in Department of Spinal Surgery, General Hospital, Ningxia Medical University. The operative time, blood loss, length of hospital stay, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, neurological function, VAS score, vertebral Cobb angle, bone healing, and postoperative complications were compared between the 2 groups.
 Results: All patients were followed up for 10 to 30 (average 22) months after the operation. In the A group, operative time, blood loss, and hospital stay were less than those in the B group (P<0.05). In the follow-up, the pain of patients was alleviated and nervous function was improved obviously in the 2 groups compared with pre-operation. The ESR and CRP at the 6 months after operation returned to the normal range in patients of the 2 groups. There were significant differences in the ESR and CRP among the pre-operation, the 6 months after operation, and the end of follow-up within the group (P<0.05), while there were no significant differences in ESR and CRP between the 6 months after operation and the end of follow-up (P>0.05). There were no significant differences in the ESR and CRP among the pre-operation, the 6 months after operation, and the end of follow-up in the 2 group (P>0.05). The Cobb angles after the operation and the end of follow-up were significanthy smaller than those before the operation (P<0.01), while there were no significant differences in Cobb angle before operation, after the operation, and the end of follow-up between the 2 groups (P>0.05). There were no significant differences in the bone healing rate at 6 months or 1 year after operation between the A group and B group (P>0.05) and the complication rate of the A group was lower than the B group (P<0.01).
 Conclusion: Clinical efficacy of posterior intervertebral surgery is satisfatory in treating single-segment thoracolumbar spinal tuberculosis with less complications.

Current clinical models emphasize certain cognitive processes in the maintenance of distressing paranoia. While a number of these processes have been examined in detail, the role of strategic cognition and self-focused attention remain under-researched. This study examined the deployment of cognitive strategies and self-focused attention in people with non-clinical paranoia. An experimental design was used to examine the impact of a threat activation task on these processes, in participants with high and low non-clinical paranoia. Twenty-eight people were recruited to each group, and completed measures of anxiety, paranoid cognition, strategic cognition and self-focused attention. The threat activation task was effective in increasing anxiety in people with high and low non-clinical paranoia. The high paranoia group experienced more paranoid cognitions following threat activation. This group also reported greater use of thought suppression, punishment and worry, and less use of social control strategies when under threat. No differences were found between the groups on measures of self-focused attention. This study shows that the threat activation task increased anxiety in people with high non-clinical paranoia, leading to increased paranoid thinking. The use of strategic cognition following threat activation varied dependent on level of non-clinical paranoia. If these differences are replicated in clinical groups, the strategies may be implicated in the maintenance of distressing psychosis, and may therefore be a valuable target for therapeutic intervention.

Studies of infants at risk for autism spectrum disorder (ASD) have proliferated, but few of these samples have been followed longer-term. We conducted a follow-up study, at age 5.5-9 years, of younger siblings of children with ASD (high-risk group, n = 79) or typical development (low-risk group, n = 60), originally recruited as infants. Children with ASD were excluded because of the focus on understanding the range of non-ASD outcomes among high-risk siblings. Using examiner ratings, parent ratings, and standardized assessments, we evaluated differences in clinical outcomes, psychopathology symptoms, autism symptoms, language skills, and nonverbal cognitive abilities. After adjusting for covariates, the high-risk group had increased odds of any clinically elevated/impaired score across measures relative to the low-risk group (43% vs. 12%, respectively). The high-risk group also had increased odds of examiner-rated Clinical Concerns (CC) outcomes (e.g., ADHD concerns, broader autism phenotype, speech-language difficulties, anxiety/mood problems, learning problems) relative to the low-risk group (38% vs. 13%, respectively). The high-risk group with CC outcomes had higher parent-reported psychopathology and autism symptoms, and lower directly-assessed language skills, than the Low-Risk Typically Developing (TD) and High-Risk TD groups, which did not differ. There were no differences in nonverbal cognitive skills. For some in the high-risk group, clinical concerns persisted from early childhood, whereas for others clinical concerns were first evident at school-age. Results suggest continued vulnerability in at least a subgroup of school-age children with a family history of ASD and suggest that this population may benefit from continued screening and monitoring into the school-age years.

The efficacy of video recording in transmitting clinical knowledge and skills to medical students was tested by recording on videotape demonstrations of physical examinations given by five clinicians to a randomly selected group of 12 students (personal group) from the first clinical year and then showing these recordings, under identical conditions, to 13 students from the same year (video group). The efficacy of both the personal and video mediums in terms of whether content was retained was tested by a questionnaire completed by all students at the end of the sessions and by a structured clinical assessment in which students were asked to demonstrate some of the same clinical tasks three weeks after the demonstration. In answering the questionnaire the video group obtained a mean (SD) score of 20.8 (7.0) (maximum possible score 40), which was not significantly different from the score achieved by the personal group (17.4 (7.7)). The video group was able to reproduce 44 (10)% of the total clinical steps demonstrated and the personal group 45 (14)%. Videotaped demonstrations can be as effective as personal teaching of clinical methods, and video should be developed as a medium for first line clinical teaching. PMID:6428655

(1) To evaluate the spectrum of serum autoantibodies in pediatric-onset systemic lupus erythematosus (pSLE) with a focus on ethnic differences; (2) using cluster analysis, to identify patients with similar autoantibody patterns and to determine their clinical associations. A single-center cohort study of all patients with newly diagnosed pSLE seen over an 8-year period was performed. Ethnicity, clinical, and serological data were prospectively collected from 156/169 patients (92%). The frequencies of 10 selected autoantibodies among ethnic groups were compared. Cluster analysis identified groups of patients with similar autoantibody profiles. Associations of these groups with clinical and laboratory features of pSLE were examined. Among our 5 ethnic groups, there were differences only in the prevalence of anti-U1RNP and anti-Sm antibodies, which occurred more frequently in non-Caucasian patients (p < 0.0001, p < 0.01, respectively). Cluster analysis revealed 3 autoantibody clusters. Cluster 1 consisted of anti-dsDNA antibodies. Cluster 2 consisted of anti-dsDNA, antichromatin, antiribosomal P, anti-U1RNP, anti-Sm, anti-Ro and anti-La autoantibody. Cluster 3 consisted of anti-dsDNA, anti-RNP, and anti-Sm autoantibody. The highest proportion of Caucasians was in cluster 1 (p < 0.05), which was characterized by a mild disease with infrequent major organ involvement compared to cluster 2, which had the highest frequency of nephritis, renal failure, serositis, and hemolytic anemia, or cluster 3, which was characterized by frequent neuropsychiatric disease and nephritis. We observed ethnic differences in autoantibody profiles in pSLE. Autoantibodies tended to cluster together and these clusters were associated with different clinical courses.

Psychogenic non-epileptic seizures (PNES) tend to begin in adolescence and young adulthood, although the seizures can occur in a wide range of ages. In the current study, we investigated the age of onset in patients with PNES and tried to determine the correlation between the age of onset and the demographic and clinical characteristics and factors potentially predisposing to PNES. In this cross-sectional study, all patients with a clinical diagnosis of PNES were recruited at the outpatient epilepsy clinic at Shiraz University of Medical Sciences from 2008 to 2012. We dichotomized the patients into two groups; those with age of onset below 18 years (juvenile), and those with age of onset at 18-55 years (adult-onset). We studied the demographic and clinical characteristics and factors potentially predisposing to PNES between these two groups. Statistical analyses were performed using Chi square and Fisher's Exact tests and Mann-Whitney U test. Fifty-seven patients with juvenile and 129 people with adult-onset PNES were studied. Demographic characteristics of these two groups were not different significantly. Seizure characteristics and semiology in these two groups were not significantly different either. However, factors potentially predisposing to PNES were significantly different between these two groups. History of being abused, academic failure, epilepsy or family history of epilepsy were more frequently observed in juvenile PNES, while medical comorbidities were more frequent among patients with adult-onset PNES. Age of onset of PNES is not correlated with the clinical manifestations; however, factors potentially predisposing to PNES are significantly different in patients with juvenile compared to those with adult-onset PNES.

HIV/Aids patients present a change of microbiota associated with host immunodeficiency. Photodynamic therapy (PDT) showed as a promising and viable alternative in reducing microbiota. Present study evaluate effectiveness of photodynamic therapy in periodontal disease of AIDS patients with highly activity antiretroviral therapy (HAART) failure, measuring the clinical periodontal parameters and periodontal microbiota. Twelve patients with HARRT resistance (R group) divided into two groups (control and PDT) and 12 patients with no HAART resistance (NR group) divided into two groups (control and PDT). The results show the difference in baseline of CD4 cells count, NR group 640.0 +/- 176.2 cells/mm3 R group and 333.3 +/- 205.8 cells / mm3 (p<0.05), and in 8.3% detectable viral load in NR group and 75% detectable (p <0.001) in R group. As clinical periodontal parameters (PD and CAL), PDT was more effective than the control group only in the NR group (p <0.05%), moreover, there was no difference in the evaluation of clinical periodontal parameters between the both R groups (p>0.05%). Microbiological evaluation in R group presents a general reduction in the Aa at 3 and 6 months. Furthermore, demonstrated a reduction of Pg in all groups at 6 months and in R group at 3 months. The impact assessment of photodynamic therapy in patients with different levels of immunosuppression determined that the combination of mechanical periodontal treatment with photodynamic therapy in patients with HAART failure did not cause additional benefits. Therefore, PDT in this study could not been indicated in HAART resistance patients.

The aim of our study is to examine effects of aerobic and Pilates exercises on disability, cognition, physical performance, balance, depression and fatigue in relapsing-remitting Multiple Sclerosis (MS) patients as compared to healthy controls. The subjects were divided as aerobic exercise (n = 26), Pilates (n = 9), and the healthy control group (n = 21). We used MSFC, physical performance, Berg balance scale, Beck depression scale, fatigue impact scale. All evaluations were performed before and after exercise training. There are statistically meaningful differences between Nine hole testing, PASAT 3, physical performance and fatique impact scale before and after aerobic exercise. Also we found significant difference for physical performance in the Pilates group. There are no significant differences in measures of fatique impact scale and depression between aerobic exercise group and the healthy controls after exercise. We found significant differences between Pilates and control group's after measurements except depression. There were significant differences between the Pilates and aerobic group for cognitive tests in favor of the Pilates group. Aerobic exercise and clinical Pilates exercises revealed moderate changes in levels of cognitive, physical performance, balance, depression, fatigue in MS patients.

A study was undertaken to test the hypothesis that clinical photographic records can be used to motivate oral hygiene performance in mentally handicapped adults. Plaque reduction over the period of the study was shown to be higher in the test group than the control group but differences between the test and control groups were not statistically significant. The small numbers involved (29) and the difficulties in matching subjects may have mitigated against demonstrating a statistically significant difference between the two groups. All participants demonstrated high levels of toothbrushing ability during the practical aspects of the study but this was not maintained through daily oral hygiene practices in the majority of subjects.

Methadone hydrochloride treatment is the most common pharmacological intervention for opioid dependence, and recent interest has focused on expanding methadone treatment availability beyond traditional specially licensed clinics. However, despite recommendations regarding effective dosing of methadone, controlled clinical trials of higher-dose methadone have not been conducted. To compare the relative clinical efficacy of moderate- vs high-dose methadone in the treatment of opioid dependence. A 40-week randomized, double-blind clinical trial starting in June 1992 and ending in October 1995. Outpatient substance abuse treatment research clinic at the Johns Hopkins University Bayview Campus, Baltimore, Md. One hundred ninety-two eligible clinic patients. Daily oral methadone hydrochloride in the dose range of 40 to 50 mg (n = 97) or 80 to 100 mg (n = 95), with concurrent substance abuse counseling. Opioid-positive urinalysis results and retention in treatment. By intent-to-treat analysis through week 30 patients in the high-dose group had significantly lower rates of opioid-positive urine samples compared with patients in the moderate-dose group (53.0% [95% confidence interval [CI], 46.9%-59.2%] vs 61.9% [95% CI, 55.9%-68.0%]; P = .047. These differences persisted during withdrawal from methadone. Through day 210 no significant difference was evident between dose groups in treatment retention (high-dose group mean retention, 159 days; moderate-dose group mean retention, 157 days). Nineteen (33%) of 57 patients in the high-dose group and 11 (20%) of 54 patients in the moderate-dose group completed detoxification. Both moderate- and high-dose methadone treatment resulted in decreased illicit opioid use during methadone maintenance and detoxification. The high-dose group had significantly greater decreases in illicit opioid use.

The aim of this study was to investigate the correlation between the natriuretic peptide precursor B (NPPB) gene single nucleotide polymorphism (SNP) c.-1298 G/T and pulse pressure (PP) of the Chinese Han population and the association between genotype and clinical indicators of hypertension. Peripheral blood was collected from 180 unrelated patients with hypertension and 540 healthy volunteers (control group), and DNA was extracted to amplify the 5'-flanking region and 2 exons of the NPPB gene by polymerase chain reaction; the fragment was sequenced after purification. The clinical data of all subjects were recorded, the distribution of the NPPB gene c.-1298 G/T polymorphism was determined, and differences in clinical indicators between the two groups were evaluated. The mean arterial pressure PP, and creatinine levels were significantly higher in the hypertension group than in the control group (P<0.05), but no other clinical indicators differed between the groups. There were no significant differences in genotype frequency and distribution of the NPPB gene c.-1298 G/T polymorphism between the hypertension group and the control group (P>0.05); in the control group, the mean PP of individuals with the SNP c.-1298 GG genotype was greater than that of individuals with the GT+TT genotype (P<0.05). In conclusion, there was no significant correlation between the NPPB gene c.-1298 G/T polymorphism and the incidence of essential hypertension in the Han population; however, the PP of the SNP c.-1298 GG genotype was greater than that of the GT+TT genotype in the control group.

The aim of the study was to assess immune response to honeybee venom in relation to the degree of exposure, time after a sting and clinical symptoms. Fifty-four volunteers were divided into 2 groups: beekeepers and a control group. The serum levels of total IgE (tIgE), bee venom-specific IgE (venom sIgE), phospholipase A2-specific IgE (phospholipase A2 sIgE), tryptase and venom-specific IgG4 (venom sIgG4) were determined. In beekeepers, diagnostic tests were performed within 3 hours following a sting and were repeated after a minimum of 6 weeks from the last sting. In individuals from the control group, the tests were performed only once, without a sting. The tests showed significant differences in venom sIgE (beekeepers' median = 0.34 kUA/l, control group median = 0.29 kUA/l), baseline serum tryptase (beekeepers' median = 4.25 µg/l, control group median = 2.74 µg/l) and sIgG4 (beekeepers' median = 21.2 mgA/l, control group median = 0.14 mgA/l), confirming higher levels of the tested substances in the beekeepers than in the control group. A significant positive correlation was observed between phospholipase A2 sIgE concentration and severity of clinical symptoms after a sting in the group of beekeepers. It was also demonstrated that the clinical symptoms after a sting became less severe with increasing age of the beekeepers. The differences in the immune response to a bee sting between the beekeepers and individuals not exposed to bees were probably due to the high exposure of the beekeepers to honeybee venom allergens. This may suggest a different approach to the bee venom allergy diagnostic tests in this occupational group.

During stimulation, Group IV needed significantly more days of stimulation as compared to Group II [8.09 ± 1.25 vs. 7.62 ± 1.17; P < 0.05], but was the group in which more oocytes were recovered [Group I: 9.43 ± 4.99 vs. Group II: 8.96 ± 4.82 vs. Group III: 8.78 ± 3.72 vs. Group IV: 11.62 ± 5.80; P < 0.05]. No significant differences were seen between the groups in terms of clinical and ongoing pregnancy, but among patients in whom two embryos with similar quality parameters (ASEBIR) were transferred, the group treated with hp-hMG alone achieved a significantly greater clinical pregnancy rate as compared to all other groups [Group I: 31.6%, Group II: 56.4%, Group III: 28.7%, Group IV: 32.7%; P < 0.05]. Although randomized clinical trials should be conducted to achieve a more reliable conclusion, these observations support the concept that stimulation with hp-hMG could be beneficial in normal responders women undergoing pituitary suppression with GnRH antagonists.

Standardized Diagnostic Interviews (SDIs) such as the Mini International Neuropsychiatric Interview (MINI) are widely used to systematically screen for psychiatric disorders in research. To support generalizability of results to clinical practice, we assessed agreement between the MINI and clinical diagnoses. Agreement was assessed in a large, real life dataset (n = 7016) using concordance statistics such as sensitivity, specificity, efficiency and area under the curve (AUC). 41.5% of clinical diagnoses were mood disorders, 26.5% were anxiety disorders. Overall, we found moderate agreement between MINI and clinical diagnoses (median efficiency: 0.92, median AUC: 0.79). For mood disorders, the AUC for all participants showed a range between 0.55 and 0.81 (median: 0.73), and for anxiety disorders the AUC ranged from 0.78 to 0.88 (median: 0.83). The AUC showed better agreement for mood disorders in the single diagnosis group than in the total group (median 0.77 vs. 0.71). For anxiety disorders, the AUC for the single diagnosis group was comparable to the AUC of the total group (median: 0.81 vs. 0.83 respectively). Numbers of false positives were high for both mood and anxiety diagnoses, but less so in the single diagnosis group. Time lag between MINI and clinical diagnosis, the availability of only the primary clinical diagnosis, and relatively high severity of the current sample are limitations of the current study. Agreement between MINI and clinical diagnoses was moderate at best, which partly reflects the difference between the different measures used in the current study. Copyright © 2017 Elsevier B.V.

To compare 5-day regimen of levofloxacin 750 mg IV daily with 7-14-day conventional regimen of levofloxacin 500 mg intravenous to oral (IV/PO) daily for treatment of community-acquired pneumonia (CAP) in Chinese population. This was a non-inferiority study to assess the difference of clinical efficacy at the end of treatment (EOT) between two regimens. Adult CAP patients with CURB-65 score 0-2 were enrolled from 17 hospitals in China from November 2012 to July 2014. The subjects were randomized into levofloxacin 750 or 500 mg group and the clinical data were collected. Sputum and blood specimens were sent for bacterial culture. The urinary antigen of Streptococcus pneumoniae ( S. pneumoniae ) was detected as well. At EOT, the clinical efficacy (primary endpoint), microbiological efficacy and safety were evaluated. A total of 457 patients were enrolled. Intent-to-treat (ITT) for primary endpoint analysis and per-protocol set (PPS) populations were 448 and 427 patients respectively. The therapeutic durations were 4.86 and 10.35 days and the mean drug exposure was 3,641.4 and 5,169.6 mg in 750 and 500 mg groups respectively. The clinical efficacy rate was 91.40% (202/221) in 750 mg group and 94.27% (214/227) in 500 mg group (ITT, P=0.2449). The difference in clinical efficacy rate was -2.87 (95% CI: -7.64, 1.90) between the two groups. The non-inferiority hypothesis of two groups was tenable (Δ=10%). The bacterial eradication rate was 100.00% in both groups. The most common drug-related clinical adverse events were injection site and gastrointestinal reactions. The most common drug-related laboratory abnormalities were WBC decrease and ALT/AST elevation. No statistical difference was found between two groups (P>0.05). The 5-day regimen of levofloxacin 750 mg daily is non-inferior to 7-14-day conventional regimen of 500 mg daily in clinical efficacy for treatment of mild to moderate Chinese CAP population. The short course regimen allows the reduction of antimicrobial drug exposure and is well tolerated.

In spite of previous conflicting results, an adjuvant role of selenium in the treatment of Graves' disease (GD) hyperthyroidism has been proposed. To address this issue, a randomized clinical trial was carried out aimed at investigating whether selenium is beneficial on the short-term control of GD hyperthyroidism treated with methimazole (MMI). Thirty newly diagnosed hyperthyroid GD patients were randomly assigned to treatment with: (i) MMI or (ii) MMI plus selenium. Primary outcomes were: control of hyperthyroidism and clinical and biochemical manifestations of hyperthyroidism [heart rate, cholesterol, sex hormone-binding globulin (SHBG), hyperthyroidism symptoms] at 90 days. Baseline features of the two groups did not differ. Serum selenium at baseline was similar in the two groups and within the recommended range to define selenium sufficiency. Selenium increased with treatment in the MMI-selenium group and became significantly higher than in the MMI group. Serum malondialdehyde, a marker of oxidative stress, was similar in the two groups and decreased significantly with treatment, with no difference between groups. Administration of MMI was followed by a reduction of FT 3 and FT 4 , with no difference between groups. Heart rate, SHBG and symptoms of hyperthyroidism decreased, whereas total cholesterol increased in both groups with no difference between groups. Our study, carried out in a selenium-sufficient cohort of GD patients, failed to show an adjuvant role of selenium in the short-term control of hyperthyroidism. However, selenium might be beneficial in patients from selenium-deficient areas, as well as in the long-term outcome of antithyroid treatment.

Gated radionuclide ventriculography (RNV) may be used for the evaluation of the right ventricular function. However, the accuracy of the method should be clinically validated in patients suffering from diseases with specific pathology of the right ventricle (RV) and with possible left ventricular (LV) interaction. Three groups of 15 patients each, diagnosed with arrhythmogenic right ventricular dysplasia (ARVD), pulmonary artery hypertension (PAH) or atrial septal defect (ASD) were compared to a group of normal subjects. The parameters for both ventricles were evaluated separately (ejection fractions: LVEF and RVEF, and intraventricular synchronism quantified as phase standard deviation: LVPSD and RVPSD) as well as the relation or interdependence of the right to left ventricle (RV/LV volume ratio, LV/RV ejection fraction and stroke volume ratios, and interventricular synchronism). All the variables as a whole were analyzed to identify groups of patients according to their functional behaviour. Significant differences were found between the patients and control group for the RV function while the LV function remained mostly within normal limits. When the RV function was considered, the control group and ASD patient group showed differences regarding the ARVD and PAH patients. On evaluating the RV/LV ratios, differences were found between the control group and the ASD group. In the PAH patients, LV function showed differences in relation to the rest of the groups. RNV is a reliable clinical tool to evaluate RV function in patients with RV abnormality. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

The purpose of this study was to address the need for effective educational interventions to promote students' clinical decision making (CDM) within clinical practice environments. Researchers used a quasi-experimental, non-equivalent groups, posttest-only design to assess differences in CDM ability between intervention group students who participated in analogy-guided learning activities and control group students who participated in traditional activities. For the intervention, analogy-guided learning activities were incorporated into weekly group discussions, reflective journal writing, and questioning with clinical faculty. The researcher-designed Assessment of Clinical Decision Making Rubric was used to assess indicators of CDM ability in all students' reflective journal entries. Results indicated that the intervention group demonstrated significantly higher levels of CDM ability in their journals compared with the control group (ES(sm) = 0.52). Recommendations provide nurse educators with strategies to maximize students' development of CDM ability, better preparing students for the demands they face when they enter the profession.

To investigate the clinical effects of surgical vs manual reduction of ankle fractures. From March 2006 to April 2010,301 patients with ankle fractures were analyzed retrospectively, of whom 134 patients were treated by manual reduction and plaster fixation, and the other 167 patients underwent surgical treatment. In manual reduction group, there were 86 males and 48 females with a mean age of (38.2 +/- 15.7) years, involving Weber-Denis A in 55 cases,Weber-Denis B in 60 cases, and Weber-Denis C in 19 cases. In surgical reduction group, there were 115 males and 52 females with a mean age of (39.6 +/- 11.9) years, involving Weber-Denis A in 59 cases, Weber-Denis B in 52 cases and Weber-Denis C in 56 cases. The score of the ankle's symptoms and function was calculated according to Mazur,and the difference was analyzed by Chi-squire test. Of the 114 patients with Weber-Denis A, 55 patients were in manual reduction group, with excellent, good, acceptable and poor results in 18, 20, 11 and 6 patients respectively vs 26, 25, 6 and 2 in surgical reduction group of 59 patients. In patients with Weber-Denis B, there were 60 patients in manual reduction group, with excellent, good, acceptable and poor results in 20 , 26, 8 and 6 patients vs 25, 21, 5, and 1 in surgical reduction group of 52 patients. There was no significant difference in clinical effects between the two group of Weber-Denis A and B. The remaining 75 patients belonged to Weber-Denis C, of whom 19 patients were in manual reduction group,with excellent, good, acceptable and poor results in 2, 3, 7 and 7 patients vs 21, 18, 11 and 6 in surgical reduction group of 56 patients. There was no significant difference in clinical effects between the two groups of Weber-Denis C (P=0.007). The clinical effect of surgical reduction group was obviously better than that of manual reduction group for Weber-Denis C, and therefore surgical intervention is recommended for this type of fracture.

Aim Main endpoint was a response rate to therapy; secondary endpoints were disease-free survival, overall survival, acute and late toxicities, specially in terms of anorectal and urinary continence. Background Radiochemotherapy for anal cancer achieves a good clinical response, locoregional control, anal function preservation. However, oncologic outcomes can differ using radiotherapy plus fluorouracil and mytomicin vs. cisplatin and fluorouracil. Methods Between 2000 and 2012, 27 anal cancer patients receiving radiotherapy combined with two different radiochemotherapy schedules, fluorouracil and mytomicin (group A) and cisplatin plus fluorouracil (group B). The Kaplan–Meier method was also used to estimate local control, overall survival and disease free survival. Statistical significance between curves was evaluated using the Log-rank test. Results Complete pathological response was found in 85.2% of patients, with higher rates of response in the group A (100% vs. 63.6%, p = 0.039). No significantly difference was found between the two groups for the other endpoints. Low rates of both acute and late toxicities were recorded. Conclusion Radiotherapy plus fluorouracil and mytomicin provide a better complete pathological response than radiotherapy plus cisplatin and fluorouracil and a greater rate of anal sphincter function preservation. Globally, radiochemotherapy of the anal cancer provides excellent clinical outcomes with a good profile of acute and late toxicity, without difference between the two groups studied. PMID:25859401

Objective Guided internet-based intervention beyond hearing aid (HA) fitting has been shown to be efficacious in randomised controlled trials (RCTs). However, internet interventions have rarely been applied clinically as a part of regular aural rehabilitation (AR). Our aim was to evaluate the effectiveness of internet-based AR for HA users from a clinical population. Outcome measures The Hearing Handicap Inventory for the Elderly (HHIE) was used as the primary outcome measure, and the Communication Strategies Scale (CSS) and the Hospital Anxiety and Depression Scale were used as secondary outcome measures. All questionnaires were administered before and directly after the intervention and at 6 months postintervention. Methods We used a parallel group design (RCT). The data were collected in 2013–2014 at three different clinics. Seventy-four HA users were randomly assigned to receive either full internet-based AR (intervention group, n=37) or one element of the internet-based AR (control group, n=37). Results Data were analysed following the intention-to-treat principle. Each group showed improved HHIE scores over time and did not differ significantly from each other. The intervention group showed significantly greater improvement compared with the control group for the CSS total and the non-verbal subscale scores. The intervention group and control group were also subdivided into two age groups: 20–59 years and 60–80 years. Significantly better improvement on the CSS total and non-verbal subscale scores was found in the older group compared with the younger participants. Conclusions This study indicates that participants in an internet-based intervention applied in general clinical practice showed improved self-reported communication skills compared with a control group. Receiving a full intervention was not more effective in improving self-reported hearing problems than receiving just one element of the internet-based intervention.

To investigate the adverse effects of acupuncture on the prognosis, and effectiveness of acupuncture combined with far infrared ray in the patient of acute Bell's facial paralysis within 48 h. Clinically randomized controlled trial was used, and the patients were divided into 3 groups: group A (early acupuncture group), group B (acupuncture combined with far infrared ray) and group C (acupuncture after 7 days). The facial nerve functional classification at the attack, 7 days after the attack and after treatment, the clinically cured rate of following-up of 6 months, and the average cured time, the cured time of complete facial paralysis were observed in the 3 groups. There were no significant differences among the 3 groups in the facial nerve functional classification 7 days after the attack, the clinically cured rate of following-up of 6 months and the average cured time (P > 0.05), but the cured time of complete facial paralysis in the group A and the group B were shorter than that in the group C (P < 0.05). The patient of acute Bell's facial paralysis can be treated with acupuncture and moxibustion, and traditional moxibustion can be replaced by far infrared way.

In the field of Neurology good clinical reasoning skills are essential for successful diagnosing and treatment. Team-based learning (TBL), an active learning and small group instructional strategy, is a promising method for fostering these skills. The aim of this pilot study was to examine the effects of a supplementary TBL-class on students' clinical decision-making skills. Fourth- and fifth-year medical students participated in this pilot study (static-group comparison design). The non-treatment group (n = 15) did not receive any additional training beyond regular teaching in the neurology course. The treatment group (n = 11) took part in a supplementary TBL-class optimized for teaching clinical reasoning in addition to the regular teaching in the neurology course. Clinical decision making skills were assessed using a key-feature problem examination. Factual and conceptual knowledge was assessed by a multiple-choice question examination. The TBL-group performed significantly better than the non-TBL-group (p = 0.026) in the key-feature problem examination. No significant differences between the results of the multiple-choice question examination of both groups were found. In this pilot study participants of a supplementary TBL-class significantly improved clinical decision-making skills, indicating that TBL may be an appropriate method for teaching clinical decision making in neurology. Further research is needed for replication in larger groups and other clinical fields.

To explore gender differences in perceptions of 1) barriers and motivators to participation in clinical trials and perceived need of clinical trials and 2) perceptions of risks and benefits of participation in clinical trials in African American men and women. Focus groups were conducted among African American participants by gender. A total of 67 African American participated in the focus groups. All focus groups were audio-taped and transcribed verbatim. Data analysis was performed by combining the key elements of grounded theory and content analysis with the assistance of the qualitative software ATLAS.ti 5.0. Different themes emerged for men versus women. The business and economic of research were important to male participants. The researcher-participant relationship emerged as one of the strongest themes related to potential female participation in research. Focus group results indicate that African American men and women present different preferences, beliefs and barriers to participation. Men expressed the desire to know information on funding issues, financial benefit and impact of the research. Women expressed the desire to be treated respectfully and as an individual as opposed to just a study subject. Integrating gender preferences into researcher-participant interactions, advertisement, informed consent delivery and advertisement of research studies may lead to increased participation rates. Discussing and presenting relevant information on clinical research funding mechanisms, and the business of clinical research with potential participants may be helpful in building trust with the researcher and the research team. Creating a process for information exchange and methods to minimize the power imbalance between the researcher and participant may also build trust and help participants feel more comfortable to participate in research.

2017-03-01

In a previous biomechanical study, eccentric glenospheres with more inferior position of the center of rotation were shown to improve range of motion and reduce the incidence of scapular notching after reverse total shoulder arthroplasty (RSA). The purpose of this study was to compare the clinical and radiological results of RSA using an eccentric glenosphere to those using a concentric glenosphere and to determine the usefulness of the eccentric glenosphere. From 2009 to 2015, we performed a retrospective review of 20 consecutive patients who underwent RSA using a deltopectoral approach. Nine patients underwent RSA using a concentric glenosphere (group A) while 11 had an eccentric glenosphere (group B). The average follow-up period was 13.9 months (range, 12 to 18 months). All glenoid components were placed with 15° of inferior tilt. Clinical results were assessed using the visual analog pain scale score (VAS), the American Shoulder and Elbow Surgeon (ASES) score, the Korean shoulder scoring system (KSS), and the Constant score. On radiological evaluation, prosthesisscapular neck angle (PSNA), peg-glenoid rim distance (PGRD), scapular neck-inferior glenoshere rim distance (inferior glenoshpere overhang), acromion-greater tuberosity (AT) distance, glenoid-greater tuberosity (GT) distance, and severity of notching according to the Nerot-Sirveaux classification were assessed. The clinical results improved significantly in both groups, but there was no statistically significant difference between the two groups. A significant intergroup difference was observed with regard to PGRD (24.8 ± 1.6 mm for group A vs. 22.2 ± 1.9 mm for group B; p = 0.002) and inferior glenosphere overhang (2.0 ± 1.7 mm for group A vs. 5.8 ± 1.6 mm for group B; p = 0.000). Seven of 9 patients in group A developed notching compared with 2 of 11 patients in group B ( p = 0.022). The other radiological parameters such as inferior tilt and AT and GT distances were not significantly different between two groups. Complications such as loosening and scapular fractures did not occur. The eccentric glenosphere in RSA was more effective in reducing the rate of notching than the concentric glenosphere although clinical outcomes were not significantly different in the short-term follow-up.

To compare the distribution of capsular groups and factor H-binding protein (fHBP) variants among meningococcal isolates and non-culture clinical specimens and to assess the representativeness of group B isolates amongst group B cases as a whole. A PCR sequencing assay was used to characterise fHBP from non-culture cases confirmed from January 2011 to December 2013. These were compared to genotypic data derived from whole genome analysis of isolates received during the same period. Group W and Y strains were more common among isolates than non-culture strains. The distribution of fHBP variants among group B non-culture cases generally reflected that seen in the corresponding isolates. Nonetheless, the non-culture subset contained a greater proportion of fHBP variant 15/B44, associated with the ST-269 cluster sublineage. Differences in capsular group and fHBP distribution among culture and non-culture cases may be indicative of variation in strain viability, diagnostic practice, disease severity and/or clinical presentation. Future analyses combining clinical case information with laboratory data may help to further explore these differences. Group B isolates provide a good representation of group B disease in E&W and, therefore, can reliably be used in fHBP strain coverage predictions of recently-licensed vaccines.

A major pathogenic factor for catamenial pneumothorax is thoracic endometriosis. However, thoracic endometriosis-related pneumothorax (TERP) can develop as either catamenial or non-catamenial pneumothorax (CP). Therefore, the aim of this study was to elucidate the clinical differences between catamenial and non-catamenial TERP. The clinical and pathological data in female patients who underwent video-assisted thoracoscopic surgery at the Pneumothorax Research Center during an 8-year period were retrospectively reviewed. This study included 150 female patients with surgico-pathologically confirmed TERP. The subjects were divided into two groups, those having all of the pneumothorax episodes in the catamenial period (CP group) and those who did not (non-CP group). We compared the clinical characteristics and surgico-pathological findings between these two groups. Of the 150 TERP patients, 55 (36.7%) were classified in the CP group, and 95 (63.3%) in the non-CP group. In regard to the locations of endometriosis, all TERP patients had diaphragmatic endometriosis, while pleural implantation was recognized in 34 of the 55 (61.8%) patients in the CP group and 42 of the 95 (44.2%) patients in the non-CP group (P < 0.05). A significant difference in the proportion of patients with pleural endometriosis was observed between catamenial and non-catamenial TERP. The ectopic sites of the endometriosis may be responsible for the timing of the pneumothorax episodes. © 2015 Asian Pacific Society of Respirology.

We studied the biomarker signatures and prognoses of 3 different subtle cognitive impairment (SCI) groups (executive, memory, and multidomain) as well as the subjective memory complaints (SMC) group. We studied 522 healthy controls in the Alzheimer's Disease Neuroimaging Initiative (ADNI). Cutoffs for executive, memory, and multidomain SCI were defined using participants who remained cognitively normal (CN) for 7 years. CSF Alzheimer disease (AD) biomarkers, composite and region-of-interest (ROI) MRI, and fluorodeoxyglucose-PET measures were compared in these participants. Using a stringent cutoff (fifth percentile), 27.6% of the ADNI participants were classified as SCI. Most single ROI or global-based measures were not sensitive to detect differences between groups. Only MRI-SPARE-AD (Spatial Pattern of Abnormalities for Recognition of Early AD), a quantitative MRI pattern-based global index, showed differences between all groups, excluding the executive SCI group. Atrophy patterns differed in memory SCI and SMC. The CN and the SMC groups presented a similar distribution of preclinical dementia stages. Fifty percent of the participants with executive, memory, and multidomain SCI progressed to mild cognitive impairment or dementia at 7, 5, and 2 years, respectively. Our results indicate that (1) the different SCI categories have different clinical prognoses and biomarker signatures, (2) longitudinally followed CN subjects are needed to establish clinical cutoffs, (3) subjects with SMC show a frontal pattern of brain atrophy, and (4) pattern-based analyses outperform commonly used single ROI-based neuroimaging biomarkers and are needed to detect initial stages of cognitive impairment. © 2015 American Academy of Neurology.

Introduction Telerehabilitation enables patients to access remote rehabilitation services for patient-physiotherapist videoconferencing in their own homes. Home-based virtual reality (VR) balance training has been shown to reduce postural instability in patients with Parkinson's disease (PD). The primary aim was to compare improvements in postural stability after remotely supervised in-home VR balance training and in-clinic sensory integration balance training (SIBT). Methods In this multicenter study, 76 PD patients (modified Hoehn and Yahr stages 2.5–3) were randomly assigned to receive either in-home VR telerehabilitation (n = 38) or in-clinic SIBT (n = 38) in 21 sessions of 50 minutes each, 3 days/week for 7 consecutive weeks. VR telerehabilitation consisted of graded exergames using the Nintendo Wii Fit system; SIBT included exercises to improve postural stability. Patients were evaluated before treatment, after treatment, and at 1-month follow-up. Results Analysis revealed significant between-group differences in improvement on the Berg Balance Scale for the VR telerehabilitation group (p = 0.04) and significant Time × Group interactions in the Dynamic Gait Index (p = 0.04) for the in-clinic group. Both groups showed differences in all outcome measures over time, except for fall frequency. Cost comparison yielded between-group differences in treatment and equipment costs. Conclusions VR is a feasible alternative to in-clinic SIBT for reducing postural instability in PD patients having a caregiver. PMID:29333454

Treating tic disorder is challenging. No trial has ever examined whether twice weekly aripiprazole is effective for treating tic disorders. Participants of this 8-week randomized controlled parallel-group clinical trial were a clinical sample of 36 children and adolescents with tic disorder. Yale global tic severity scale was used to assess the outcome. Both groups received daily dosage of aripiprazole for the first 14 days. Then, one group received daily dose of aripiprazole while the other group received twice weekly dosage of aripiprazole for the next 46 days. The patients were assessed at baseline, week 2, 4, and 8. Tic scores decreased in both group significantly 22.8 (18.5) versus 22.0 (11.6). Moreover, there was no between group difference. The final mean (SD) score of motor and vocal tics in the group treated with daily treatment was not significantly different from the twice weekly group (Cohen's d = 0.36). The odds ratios for sedation and increased appetite were 3.05 and 3, respectively. For the first time, current findings support that twice weekly aripiprazole efficacy was not different from that of daily treatment. The rate of drowsiness in the twice weekly treatment group was less than that of the daily treatment group. This trial was registered at http://www.irct.ir.

The politics of nursing: a case study--clinical grading.

PubMed

Gavin, J N

1995-08-01

This paper is a study of the clinical grading policy for nurses in the United Kingdom and the extent to which the participating groups in the policy development process realized their objectives. The study is based on the literature available at the time of the research and the results of structured interviews with a range of individuals involved in the policy process. The results expose the cleavages between the different representative groups on the staff side. They also shed light on the differing power bases of the groups involved. In particular, they expose the weakness of nursing as a professional pressure group and the strength of the state and its agents in determining the outcomes of policy in the public arena. It is suggested that this weakness vis-à-vis the state is responsible for the failure of nurses to achieve a reward system which recognizes the value of clinical nursing expertise, and that the 'clinical grading' system, in practice, is having the opposite effect. The policy is explored from its origins, its acceptance on to the political agenda, its negotiation and agreement, its contentious implementation, the final outcomes, and its failure to establish a valid 'clinical' pay structure.

The hypothesis of this 5-y randomized clinical trial was that there would be no significant difference in the satisfaction of edentulous participants with removable complete overdentures attached to 1 or 2 mandibular implants. Secondary aims were to test changes in satisfaction between and within the groups from baseline to 5 y and differences between the groups in implant survival and prosthodontic maintenance over 5 y. Each of the 86 participants (mean age, 67 y) was randomly allocated to receive either 1 implant in the midline (group 1) or 2 implants in the canine areas (group 2) attached to a mandibular overdenture opposing a maxillary complete denture. Satisfaction was self-assessed by participants on a visual analog scale at baseline prior to implants, as well as at 2 mo and 1, 3, and 5 y with implant overdentures, whereas implant survival and prosthodontic maintenance were assessed by clinical examination. After 5 y, 29 participants in group 1 and 33 in group 2 were available, with most dropouts due to death. Satisfaction with the implant denture after 5 y was significantly (P < 0.001) higher than at baseline in both groups and remained with no significant difference (P = 0.32) between the groups. No implants failed in group 1 but 5 failed before loading in 4 participants in group 2. Most participants required maintenance or occasionally denture replacement, and although differences between the groups were not statistically significant, group 1 experienced almost twice as many fractured dentures usually adjacent to the implant attachment. We conclude that there were no significant differences after 5 y in satisfaction or survival of implants with mandibular overdentures retained by 1 implant or 2 implants. Additional research is required to confirm long-term treatment effectiveness of single-implant dentures and the implications of prosthetic maintenance with implant overdentures (ClinicalTrials.gov: NCT02117856). © International & American Associations for Dental Research 2014.

The replication of natural teeth, especially with single-tooth restorations, represents a challenge. Similar to metal ceramic crowns, different designs of zirconia substructures have been suggested to improve the esthetic results of zirconia ceramic crowns. The purpose of the study was to analyze the color of the cervical portion of single zirconia ceramic crowns fabricated with different zirconia coping designs. The color, measured on the CIELAB color scale, of 3 different groups of restorations (n=10) fabricated with zirconia coping (Lava) and feldspathic porcelain (Noritake Super Porcelain) was analyzed with a spectrophotometer. Conventional zirconia crowns with zirconia facial margins were compared with ceramic crowns with porcelain facial margins and either a horizontal reduction of the zirconia coping (1.0 mm reduction) or an additional vertical reduction (1.0 mm additional reduction). The 3 groups, each with a different coping extension, were examined with a 1-way ANOVA and the Fisher exact test, and the differences of the groups were evaluated by applying ΔE thresholds (α=.05). The mean color difference among all the groups was not clinically significant (ΔE<3.7). Reduced color differences were present between the 2 porcelain butt margin groups of crowns (ΔE=1.06, between group H and V). Increased differences were present between the zirconia margin group and the porcelain butt margin group (ΔE=2.54 between group C and H; ΔE=2.41 between group C and V). Lab* values were examined in all the groups of crowns to determine the clinical implications. Within the limitation of the study, no significant differences were present among the tested groups of crowns. Nevertheless, although some differences were present between the zirconia margin group and the porcelain butt margin group, reduced differences were present between the 2 different cutback designs.

Immunization against human platelet alloantigens (HPAs) is associated with a number of clinical complications. The detection and identification of clinically relevant platelet antibodies are important for the diagnosis and management of patients affected with immune-mediated thrombocytopenias. Human platelet alloantigen frequencies and the characteristics of antiplatelet antibodies vary widely between ethnic groups. Since 2008, the importance of platelet immunology in the field of transfusion medicine has gained greater recognition by clinical laboratories in China. Laboratories in China have established and improved methods for platelet antibody detection and HPA genotyping techniques, which are used for the diagnosis of alloimmune platelet disorders in clinic and research environments. Research has revealed the frequencies of HPA alleles in different Chinese ethnic groups and compared the differences in HPA gene frequencies between the Chinese Han and other ethnic groups of the world. Production of anti-CD36 isoantibodies is an important risk factor for immune-mediated thrombocytopenia in the Chinese population. Advances in research and clinical application of platelet immunology have significantly improved the clinical diagnosis, treatment including transfusion support, and prevention of alloimmune platelet disorders in the Chinese population.

To observe the clinical effect and efficacy of Xiaozhi Capsule (XZC), a Chinese medicine preparation for tonifying Gan-Shen, invigorating Pi to dissipate dampness (TGSIPDD) on total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and endothelin (ET) in treating patients with hyperlipidemia. Totally 120 primary hyperlipidemia patients were randomly assigned to the treatment group (80 cases) and the control group (40 cases). Those in the treatment group took XZC, while those in the control group took Xuezhikang Capsule (XZKC). The serum TC, TG, HDL-C, LDL-C, and ET were detected and evaluated after 8 weeks of treatment. In the treatment group TC was reduced by 25.60%, TG by 33.70%, LDL-C by 32.90%, and ET by 11.02%, while HDL-C was elevated by 24.20%. In the control group, TC was reduced by 24.80%, TG by 33.50%, LDL-C by 31.30%, and ET by 12.05%, while HDL-C was elevated by 20.90%. There was statistical difference in the two groups when compared with before treatment (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups after treatment (P > 0.05). The integrals for main symptoms after treatment obviously decreased in the two groups, showing statistical difference when compared with before treatment in the same group (P < 0.01). But there was no statistical difference in the aforesaid indices between the two groups (P > 0.05). After 8 weeks of treatment, symptoms such as vertigo, heavy sensation of head, palpitation, chest distress, dry mouth and thirsty were obviously improved after treatment. There was statistical difference in the improvement of tinnitus after treatment in the treatment group (P < 0.01). The total effective rate was 86.25% in the treatment group and 82.50% in the control group, showing no statistical difference (P > 0.05). XZC showed certain effects on each blood lipid index and ET of hyperlipidemia patients. It had better improvement of clinical symptoms with reliable efficacy.

In a randomised, placebo-controlled, double-blind clinical study the clinical efficacy and safety of Crataegus extract WS 1442, standardised to 18.75% oligomeric procyanidines, were investigated in 40 female and male outpatients suffering from congestive heart failure NYHA class II. Following a wash-out period of up to seven days, the patients were randomised to be treated for 12 weeks with either WS 1442 (3 x 1 capsule) or placebo. The primary outcome variable was exercise tolerance determined with bicycle exercise testing; as a secondary outcome variable the difference of the double product was calculated. On average, the exercise tolerance increased by 66.3 W x min (10.8%) in the WS 1442 group while in the placebo group a reduction of 105.3 W x min (16.9%) was measured. This difference between the groups was borderline statistically significant (p = 0.06). During the three month therapy the difference of the double product (heart rate x systolic blood pressure x 10(-2)) decreased by 14.4 mmHg s(-1) (26.8%) in the WS 1442 group and by 1.3 mmHg s(-1) (2.7%) in the placebo group, respectively. Recording of laboratory parameters and adverse events showed that WS 1442 was safe and well tolerated. The data show that Crataegus extract WS 1442 is clinically effective in patients with congestive heart failure corresponding to NYHA class II.

Recent studies have demonstrated the beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on physiological processes and on a variety of chronic inflammatory diseases, including periodontal diseases. In this study, we evaluated the impact of omega-3 PUFAs in conjunction with scaling and root planing (SRP) on salivary markers in patients with chronic periodontitis. Thirty systemically healthy subjects with chronic periodontitis were enrolled and randomly allocated into two groups. The control group (n = 15) was treated with SRP + placebo whereas the test group was treated with SRP and dietary supplementation of low-dose omega-3 PUFAs (6.25 mg eicosapentaenoic acid and 19.19 mg docosahexaenoic acid). Clinical parameters were taken at baseline, 1, 3 and 6 mo following therapy. Saliva samples were obtained at the same time intervals and analyzed for tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD). Both groups showed significant changes in clinical parameters in response to treatment compared to baseline with no significant difference between groups. Salivary TNF-α levels showed a statistically significant decrease in the test group at 6 mo compared to the control group. Salivary SOD levels increased significantly at 3 and 6 mo in the test group and at 6 mo in placebo groups compared to baseline with no statistically significant differences between the groups. The results demonstrated that dietary supplementation with low-dose omega-3 PUFAs improves salivary TNF-α without any significant impact on clinical parameters in patients with chronic periodontitis, suggesting that the systemic benefits of dietary omega-3 PUFAs may not be translated to periodontal health.

McDaniel, C

1998-06-01

There is increasing attention paid to ethics under managed care; however, few clinical-based ethics programs are reported. This paper reports the assessment and outcomes of one such program. A quasi-experimental research design with t-tests is used to assess the outcome differences between participants and control groups. There are twenty nurses in each; they are assessed for comparability. Differences are predicted on two outcomes using reliable and valid measures: nurses' time with their patients in ethics discussions, and nurses' opinions regarding their clinical ethics environments. Results reveal a statistically significant difference (p <.05) between the two groups, with modest positive change in the participants. Additional exploratory analyses are reported on variables influential in health care services.

Ethnic minorities (EM) from STI-endemic countries are at increased risk to acquire an STI. The objectives of this study were to investigate the difference in STI clinic consultation and positivity rates between ethnic groups, and compare findings between Dutch cities. Aggregated population numbers from 2011 to 2013 of 15-44 year-old citizens of Amsterdam, Rotterdam, The Hague and Utrecht extracted from the population register (N=3 129 941 person-years) were combined with aggregated STI clinic consultation data in these cities from the national STI surveillance database (N=113 536). Using negative binomial regression analyses (adjusted for age and gender), we compared STI consultation and positivity rates between ethnic groups and cities. Compared with ethnic Dutch (consultation rate: 40.3/1000 person-years), EM from Eastern Europe, Sub-Sahara Africa, Suriname, the Netherlands Antilles/Aruba and Latin America had higher consultation rates (range relative risk (RR): 1.27-2.26), whereas EM from Turkey, North Africa, Asia and Western countries had lower consultation rates (range RR: 0.29-0.82). Of the consultations among ethnic Dutch, 12.2% was STI positive. Positivity rates were higher among all EM groups (range RR: 1.14-1.81). Consultation rates were highest in Amsterdam and lowest in Utrecht independent of ethnic background (range RR Amsterdam vs Utrecht: 4.30-10.30). Positivity rates differed less between cities. There were substantial differences in STI clinic use between ethnic groups and cities in the Netherlands. Although higher positivity rates among EM suggest that these high-risk individuals reach STI clinics, it remains unknown whether their reach is optimal. Special attention should be given to EM with comparatively low consultation rates. Published by the BMJ Publishing Group Limited.

To observe the clinical efficacy on migraine treated with acupoint implantation. Sixty cases of migraine were randomized into a implantation group and an electroacupuncture (EA) group, 30 cases in each one. In the implantation group, implantation was used at Fengchi (GB 20), Taiyang (EX-HN 5), Waiguan (TE 5), Yanglingquan (GB 34), etc., once every 2 weeks, for 4 weeks totally. In the EA group, the acupoints were the same as the implantation group, and EA was applied to Fengchi (GB 20) and Taiyang (EX-HN 5), Yanglingquan (GB 34) and Zusanli (ST 36), once every two days, for 4 weeks totally. The visual analogue scale (VAS) was adopted before and after treatment and the clinical efficacy was compared between the two groups. After treatment, VAS score was reduced in the implantation group and the EA group as compared with that before treatment (both P < 0.01). After treatment, VAS score in the implantation group was lower than that in the EA group (P < 0.01). The difference in VAS score before and after treatment in the implantation group was improved apparently as compared with that in the EA group (P < 0.01). The total effective rate in the implantation group was higher than that in the EA group (P < 0.05). The acupoint implantation reduces VAS score in the patients of migraine and its clinical efficacy is better than that in the EA group. The therapy presents the long-term clinical effect and deserves to be promoted in clinical practice.

To explore the clinical characteristics and prognosis of patients with chronic kidney disease with unprotected left main (ULM) coronary artery disease undergoing coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). A total of 601 unprotected left main coronary artery disease patients were recruited. According to the values of endogenous creatinine clearance rate (Ccr), they were divided into three groups of <45 ml/min (n=40), 45-59 ml/min (n=96) and ≥60 ml/min (n=465). Retrospective comparisons were made for the clinical parameters and prognosis of ULM patients in different Ccr groups with different therapies. In Ccr≥60 ml/min group, the valves of left ventricular ejection fraction (LVEF) were lower in patients undergoing CABG. Patients with complete total occlusion (CTO) and complete revascularizations were much more than those undergoing PCI. In Ccr≥60 ml/min and Ccr 45-59 ml/min groups, multivessel disease was frequent in CABG-treated patients. No significant difference existed among three groups in major adverse cardiac and cerebrovascular event (MACCE), overall mortality or cardiac mortality. PCI is both safe and efficacious for chronic renal insufficiency patients with ULM.

To compare retrospectively the clinical and radiographic outcomes between cervical reconstruction with expandable cylindrical cage (ECC) and iliac crest autograft after one- or two-level anterior cervical corpectomy for spondylotic myelopathy. Forty-two patients underwent cervical reconstruction with either iliac crest autograft and plating (20 patients) or ECC and plating (22 patients). The average clinical and radiological follow-up period was 77.54 ± 44.28 months (range 14-155 months). The authors compared clinical parameters (Nurick Myelopathy Grade, modified Japanese Orthopedic Association (mJOA) scores), perioperative parameters (hospital stays, complications) and radiological parameters (Cobb's angles of the fused segments and C2-C7 segments, cervical subsidence, fusion rate). Fusion was assessed on flexion-extension X-ray films. No significant differences between the two groups were found in demographics, neurological presentation, preoperative sagittal alignment, clinical improvement and length of hospitalization. Patients of the autograft group experienced more postoperative complications, although the difference between the two treatment groups was not statistically significant (15 versus 4.5%, p=0.232). The fusion rate was 100% in both groups. The average lordotic increase of the segmental angle was significantly greater in the ECC group (p<0.05). Other radiological parameters were not significantly different in the two groups. Cervical reconstruction either with iliac crest autograft and plating or ECC and plating provides good clinical results and similar fusion rates after one- or two-level corpectomy for spondylotic myelopathy. However, the use of ECC obviates donor site complications and provides a more significant increase of lordosis in segmental angle. Copyright © 2015 Elsevier B.V. All rights reserved.

Objective: To investigate whether neutrophil to lymphocyte ratio (NLR) in peripheral blood can be an independent prognostic factor in patients with head and neck squamous cell carcinoma (HNSCC). Methods: Clinical data of 97 HNSCC patients who received surgical treatment in our department between January 2008 and January 2012 were analyzed retrospectively. The 97 patients were divided into low NLR group (NLR≤5, n =69) and high NLR group (NLR>5, n =28) according to the NLR in preoperative peripheral blood. The relationships of NLR and clinicopathological features were analyzed. Kaplan-Meier method was used for univariate survival analysis and Cox proportional hazard model for multivariate survival analysis. Results: The clinical stages were significantly different between high NLR group and low NLR group ( P <0.05), however, the age, gender, location, lymph node metastasis, smoking and alcohol of the two groups showed no significant differences ( P > 0.05 of all). Univariate survival analysis showed that smoking, lymph node metastasis, clinical stage and NLR value were risk factors for 3-year overall survival (OS) rate and relapse-free survival (RFS) rate of HNSCC patients ( P <0.05). The OS rate of high NLR and low NLR groups was 42.9% and 91.3%, and the RFS rate was 44.2% and 80.1%, respectively, with a statistically significant difference ( P <0.05 for both). Cox multivariate survival analysis showed that clinical stage and NLR were independent factors for prognostic evaluation of HNSCC patients ( P <0.05 for both). Conclusions: NLR level is significantly associated with clinical stage of HNSCC. High NLR is an independent prognostic rick factor and plays an important role in prognostic evaluation of HNSCC patients.

Navigated computer-assisted total knee arthroplasty (TKA) was introduced to expedite long-term survival based on improved postoperative implantation accuracy. However, long-term outcome data after 10 years or more are rare, even available meta-analyses show controversial study results. In a prospective randomized trial, 100 conventional TKAs (group CONV) were compared with 100 computer-assisted TKAs (group NAV) after a mean follow-up of 12 years postoperatively. A long-leg weight-bearing X-ray was performed for measuring mechanical axis of the limb, lateral distal femoral angle, and medial proximal tibial angle. Tibial slope, patella alpha angle, and radiolucent lines were also observed. Clinical investigation included evaluation of 4 different scores: Insall Knee Score, Western Ontario and MacMaster University Index score, Hospital for Special Surgery Knee Score, and visual analog scale. Based on a follow-up rate of at least 75%, no difference in TKA survival was found 12 years postoperatively: 91.5% in group CONV vs 98.2% in group NAV (P = .181). Since 5-year follow-up, no additional TKA revision had been performed in both groups. Group CONV showed a nonsignificant higher inaccuracy of neutral lower limb axis (1.8° ± 1.4°) compared to group NAV (1.6° ± 1.7°, P = .700). All X-ray assessments were not significant different within both study groups (P ≥ .068). Clinical examination showed no differences in evaluations (P ≥ .204). All collected outcome score results were similar (P ≥ .222). Twelve years postoperatively, no differences were found in terms of long-term survival, implantation accuracy, clinical outcome or score results. Copyright © 2017 Elsevier Inc. All rights reserved.

Inferring beliefs and social emotions of others has different neural substrates and possibly different roles in the pathophysiology of different clinical phases of schizophrenia. The current study investigated the neural basis for inferring others' beliefs and social emotions, as individual concepts, in 17 subjects at ultra-high risk for psychosis (UHR), 16 patients with schizophrenia and 20 healthy controls. Brain activity significantly differed from normal in both the left superior temporal sulcus (STS) and the inferior frontal gyrus (IFG) in the schizophrenia group while inferring others' beliefs, whereas those of UHR group were in the middle of those in the schizophrenia and healthy-control groups. Brain activity during inferring others' social emotions significantly differed in both the left STS and right IFG among individuals at UHR; however, there was no significant difference in the schizophrenia group. In contrast, brain activity differed in the left IFG of those in both the schizophrenia and UHR groups while inferring social emotion. Regarding the difference in direction of the abnormality, both the UHR and schizophrenia groups were characterized by hyper-STS and hypo-IFG activations when inferring others' beliefs and emotions. These findings might reflect different aspects of the same pathophysiological process at different clinical phases of psychosis. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Purpose: To evaluate the effect of oral calcium dobesilate (Doxium) on macular thickness in clinically significant macular edema (CSME). Methods: Overall, 71 eyes of 40 patients with non-proliferative diabetic retinopathy and clinically significant macular edema were included. All patients were received laser treatment for macular edema. Coherence optical tomography was used to determine the retinal thickness. Patients were randomized into two groups: group A received three Doxium capsule daily and group B received three placebo capsule daily for six months. Results: The mean macular thickness before and after treatment in the group A was 340 and 257 micrometers respectively (24.5% reduced), and in the group B was 336 micrometers and 263 micrometers respectively (21.5% reduced). Macular thickness significantly decreased after treatment in both groups and the reduction in group A is higher but the difference of reduction between the two groups was not statistically significant (P>0.05). Conclusion: In respect to the effect of adding oral Doxium to Laser Photocoagulation on the macular thickness in patients with diabetic macular edema, this study showed no statistically significant difference between Doxium and placebo.

To compare the effectiveness and safety of the methylphenidate produced in Iran (Stimdate®) with its original brand (Ritalin®) in children with Attention deficit hyperactivity disorder (ADHD). In this double-blinded randomized clinical trial, 30 patients with ADHD who were 6 to 16 years old, were divided into two groups: 15 in Stimdate® and 15 in Ritalin® group. The two groups were compared for side effects profile, Conner's Parent's Rating Scale-Persion version (CPRS-R), Child Symptom Inventory-4 (CSI-4), Clinical Global Impressions (CGI), and Children's Global Assessment Scale (CGAS), at baseline and at the 4(th) and 6(th) weeks. The subjects showed significant decreases in the CPRS-Rand CSI-4 scores and significant increase of CGAS scores during the follow-up, but there were no significant difference between Stimdate® and Ritalin® group, regarding the pattern of changes observed. The mean therapeutic dose and the number of side effects were not significantly different between the two studied groups. Both Stimdate® and Ritalin® had comparable clinical efficacy and safety in children with ADHD.

Interposition arthroplasty with bioreplaceable poly-L-D-lactic acid (PLDLA) implants has yielded promising results in reconstruction of rheumatoid hands. In this prospective clinical study we compared the PLDLA implant arthroplasty (n = 17) with that of tendon interposition (n = 12) for destruction of the trapeziometacarpal joint in arthritic patients. There was no significant difference between the two groups preoperatively. At one-year follow-up, the mean pain and function scores were 5 and 13 in the PLDLA group, and 19 and 43 in the tendon interposition group, respectively. At one-year follow-up the visual analogue scale (VAS) for function of the PLDLA group differed significantly from that of the tendon interposition group (p = 0.03). This difference was not found at three months postoperatively, and disappeared again at two-year follow-up. Otherwise, no significant difference was found between the groups in the pain or function scores, functional tests, or range of movement. Bioreplaceable interposition arthroplasty works at least as well as tendon interposition. The operation is easier.

Objective Ethnicity has been associated with clinical and experimental pain responses. While ethnic disparities in pain in other minority groups compared to whites are well described, pain in Asian Americans remains poorly understood. The purpose of this study was to characterize differences in clinical pain intensity and experimental pain sensitivity among older Asian American and non-Hispanic White (NHW) participants with knee osteoarthritis (OA). Methods Data were collected from 50 Asian Americans ages 45-85 (28 Korean, 9 Chinese, 7 Japanese, 5 Filipino, and 1 Indian) and compared to 50 age- and gender-matched NHW individuals with symptomatic knee OA pain. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Graded Chronic Pain Scale (GCPS) were used to assess the intensity of clinical knee pain. In addition, quantitative sensory testing was used to measure experimental sensitivity to heat- and mechanically-induced pain. Results Asian American participants had significantly higher levels of clinical pain intensity than NHW participants with knee OA. In addition, Asian American participants had significantly higher experimental pain sensitivity than NHW participants with knee OA. Discussion These findings add to the growing literature regarding ethnic and racial differences in clinical pain intensity and experimental pain sensitivity. Asian Americans in particular may be at risk for clinical pain and heightened experimental pain sensitivity. Further investigation is needed to identify the mechanisms underlying ethnic group differences in pain between Asian Americans and non-Hispanic Whites, and to ensure that ethnic group disparities in pain are ameliorated.

To describe and compare two extracorporeal shock wave therapy techniques for the treatment of painful subcalcaneal spur. Random assignment to two groups of treatment with two and eight months follow-up. The data were collected in outpatients. Forty-five subjects with a history of at least six months of heel pain were studied. Each subject received a three-session ultrasound-guided extracorporeal shock wave therapy (performed weekly). Perpendicular technique was used in group A (n=22, mean age 59.3 +/- 12 years) and tangential technique was used in group B (n= 23, mean age 58.8 +/- 12.3 years). Mayo Clinical Scoring System was used to evaluate each subject before the treatment and at two and eight months follow-up. Mayo Clinical Scoring System pretreatment scores were homogeneous between the groups (group A 55.2 +/-18.7; group B 53.5 +/- 20; P>0.05). In both groups there was a significant (P<0.05) increase in the Mayo Clinical Scoring System score at two months (group A 83.9 +/- 13.7; group B 80 +/- 15,8) and eight months (group A 90 +/- 10.5; group B 90.2 +/-8.7) follow-up. No significant differences were obtained comparing the Mayo Clinical Scoring System scores of the two groups at two and eight months follow-up. There was no difference between the two techniques of using extracorporeal shock wave therapy. The tangential technique was found to be better tolerated as regards treatment-induced pain, allowing higher energy dosages to be used.

Emotion dysregulation (ED) has long been recognized in clinical descriptions of attention-deficit hyperactivity disorder (ADHD), but a renewed interest in ED has advanced research on the overlap between the two entities. Autonomic reactivity (AR) is a neurobiological correlate of emotion regulation; however, the association between ADHD and AR remains unclear. Our aim was to explore the clinical differences, AR, and subjective emotional responses to visual emotional stimuli in ADHD children with and without ED. School-aged ADHD children with (n = 28) and without (n = 20) ED, according to the definition of deficiency in emotional self-regulation (DESR), and healthy controls (n = 22) were interviewed by using the Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime version (K-SADS-PL) to screen frequent psychopathologies for these ages. All subjects were evaluated with Child Behavior Checklist 6-18 (CBCL), the Strengths and Difficulties Questionnaire (SDQ), the McMaster Family Assessment Device (FAD), the School-Age Temperament Inventory (SATI), and Conners' Parent Rating Scale (CPRS-48), which were completed by parents. To evaluate emotional responses, the International Affective Picture System (IAPS) and the subjective and physiological responses (electrodermal activity and heart rate reactivity) to selected pictures were examined. Regarding clinically distinctive features, the ADHD+ED group differed from the ADHD-ED and the control groups in terms of having higher temperamental negative reactivity, more oppositional/conduct problems, and lower prosocial behaviors. In the AR measures, children in the ADHD+ED group rated unpleasant stimuli as more negative, but they still had lower heart rate reactivity (HRR) than the ADHD-ED and control groups; moreover, unlike the two other groups, the ADHD+ED group showed no differences in HRR between different emotional stimuli. The presented findings are unique in terms of their ability to clinically and physiologically differentiate between ADHD children with and without ED.

The purpose of this study is to analyze the clinical results and related complications of the femur plate system (FP) and the retrograde-inserted supracondylar nail (RISN). The study included 42 cases of periprosthetic supracondylar femoral fractures (PSF) proximal to posterior stabilized total knee arthroplasty between 2005 and 2009. Twenty-four cases of PSF were treated with the FP, and the other 18 cases were treated with the RISN. This study cohort was divided into subgroups according to the AO classification. We retrospectively compared the clinical results between the FP and RISN group. There were no significant differences between the two groups in terms of time of clinical union (p = 0.649). In the subgroup analysis, the mean operation time was significantly different only in subgroup A1 (p = 0.03). Complications were seen in 29.2 % (7/24) of patients in the FP group and 27.8 % (5/18) in the RISN group. The age during the index TKA and fracture fixation was a significant risk (p = 0.008) factor for complications between the two groups. No significant differences were found in the other factors between the two groups. The p value for operative time (p = 0.223), immobilization period (p = 0.129), ROM (p = 0.573), KSS (p = 0.379), KSS functional scores (p = 0.310) and time to union (p = 0.649). Clinical results did not differ according to the treatment methods used. Fixation method and fracture type did not cause an increase in the complication rate, but there was a trend toward higher non-union rates with the FP method and higher re-fracture rate with the RISN method. Noting the fact that only increasing age correlated with an increased complication rate, more careful attention should be paid to elderly patients in terms of both prevention and surgical care. Level III, therapeutic study.

The aim of this clinical prospective trial was to evaluate finishing effectiveness of stainless steel (SS) archwires versus titanium molybdenum alloy (TMA) archwires using SmartClip™ self-ligating brackets. Thirty-two patients were divided in two groups: a group of 21 (G1-SS) and a group of 12 (G2-TMA). The protocol consisted of two different finishing archwires coupled with self-ligating brackets: .019 × .025" SS archwires for G1-SS and .019 × .025" TMA archwires for G2-TMA. Lateral cephalometric radiographs obtained at the beginning (T1) and end (T2) of treatment were used to assess the changes in incisor inclination, and measurements of irregularity index (LII), interdental widths, arch length (AL) and arch depth (AD) were made on dental casts to investigate changes associated with crowding correction. No significant differences from T1 to T2 were found for incisors proclination and AL changes. Statistically significant differences were found for LII (higher decrease in G1-SS), maxillary AD (higher increase in G1-SS) and three interdental maxillary widths (higher in G1-SS). The statistically significant differences found were few and clinically negligible. Self-ligating brackets system coupled with .019 × .025" archwires showed good finishing effectiveness, but no clinically significant differences were found between SS and TMA. Copyright © 2013 CEO.

Clinical efficacy of the low power laser (LPL) in medical treatments is still not well established. In a double blind, placebo controlled study, we tried to find out first which type of LPL is more efficient, and second if coherence is an important character for clinical efficacy. We treated 1228 patients having different rheumatic diseases, with low power diode, used as follows: A group: IR coherent diode, continuous emission, 3 mW power; B group: IR coherent diode, pulsed emission, output power about 3 mW; C group: IR noncoherent diode continuous emission 9 mW power; D group: both IR diode lasers (continuous or pulsed) and HeNe laser, continuous emission, 2 mW power; E group: placebo laser as control group. The energy dose used for every group was the same, as well as the clinical protocols. The positive results were: 66.16% for A group; 64.06% for B group; 48.87% for C group; 76.66% for D group, and 39.07% for E group. Finally, we showed that LPL is really efficient in the treatment of some rheumatic diseases, especially when red and IR diode laser were used in combination. The type of emission (continuous or pulsed) is not important, but coherence is obviously necessary for clinical efficacy.

The aim of the study was to explore possible differences in temperament and character dimensions between 2 monodiagnostic adolescent groups of depression, namely, one with a present episode of major depression and subjects with the other being their dysthymic peers. From a multisite Western Hungarian sample of consecutively referred 14- to 18-year-old new psychiatric adolescent outpatients, 2 groups were compared: group I, n = 56 (9 males, 47 females), with major depressive disorder (MDD) and group II, n = 27 (6 males, 21 females), with a diagnosis of dysthymic disorder (DD). All other comorbid diagnoses including bipolar and double depression (MDD + DD) cases were excluded. Present suicide events, if the attempter had an underlying diagnosis of depression, were not causes for exclusion. Assessment methods used were the adapted Hungarian versions of the Mini International Neuropsychiatric Interview and the Junior Temperament (Cloninger) Character Inventory. The only difference between the major depressive and dysthymic adolescents was harm avoidance, adolescents with major depression having a higher level practice of harm avoidance, whereas the temperament type of MDD vs DD seems to differ only in the aspect of avoiding painful stress. Expectations regarding a worse degree of self-directedness and lower levels of persistence and cooperativeness in the MDD sample were not proved. No essential temperament differences were found between the 2 adolescent depressive groups. Scarce differences between temperament qualities of MDD and DD may support Akiskal's continuum theory of depressive disorders. More research and the use of closer clinical personality typologies are warranted to explore possible personality trait differences (if they exist) between clinical diagnostic groups of adolescent patients.

An international collaboration was organized to undertake a dosimetry exchange to enable the future combination of clinical data from different centers conducting neutron capture therapy trials. As a first step (Part I) the dosimetry group from the Americas, represented by MIT, visited the clinical centers at Studsvik (Sweden), VTT Espoo (Finland), and the Nuclear Research Institute (NRI) at Rez (Czech Republic). A combined VTT/NRI group reciprocated with a visit to MIT. Each participant performed a series of dosimetry measurements under equivalent irradiation conditions using methods appropriate to their clinical protocols. This entailed in-air measurements and dose versus depth measurements in a large water phantom. Thermal neutron flux as well as fast neutron and photon absorbed dose rates were measured. Satisfactory agreement in determining absorbed dose within the experimental uncertainties was obtained between the different groups although the measurement uncertainties are large, ranging between 3% and 30% depending upon the dose component and the depth of measurement. To improve the precision in the specification of absorbed dose amongst the participants, the individually measured dose components were normalized to the results from a single method. Assuming a boron concentration of 15 microg g(-1) that is typical of concentrations realized clinically with the boron delivery compound boronophenylalanine-fructose, systematic discrepancies in the specification of the total biologically weighted dose of up to 10% were apparent between the different groups. The results from these measurements will be used in future to normalize treatment plan calculations between the different clinical dosimetry protocols as Part II of this study.

Catheter ablation of atrioventricular nodal reentrant tachycardia (AVNRT) is a commonly performed electrophysiology (EP) procedure. Few data exist comparing conventional (CONV) versus novel ablation strategies from both clinical and direct cost perspectives. We sought to investigate the disposable costs and clinical outcomes associated with three different ablation methodologies used in the ablation of AVNRT. We performed a retrospective review of AVNRT ablations performed at Augusta University Medical Center from 2006 to 2014. A total of 183 patients were identified. Three different ablation techniques were compared: CONV manual radiofrequency (RF) (n=60), remote magnetic navigation (RMN)-guided RF (n=67), and cryoablation (CRYO) (n=56). Baseline demographics did not differ between the three groups except for a higher prevalence of cardiomyopathy in the RMN group ( p <0.01). The clinical end point of interest was recurrent AVNRT following the index ablation procedure. A significantly higher number of recurrent AVNRT cases occurred in the CRYO group as compared to CONV and RMN ( p =0.003; OR =7.75) groups. Cost-benefit analysis showed both CONV and RMN to be dominant compared to CRYO. Cost-minimization analysis demonstrated the least expensive ablation method to be CONV (mean disposable catheter cost = CONV US$2340; CRYO US$3515; RMN US$5190). Despite comparable clinical outcomes, the incremental cost of RMN over CONV averaged US$3094 per procedure. AVNRT ablation using either CONV or RMN techniques is equally effective and associated with lower AVNRT recurrence rates than CRYO. CONV ablation carries significant disposable cost savings as compared to RMN, despite similar efficacy.

Objectives: The antiplaque and antigingivitis effect of Lippia Sidoides (LS) was evaluated in this in vivo investigation. Material and Methods: Twenty-three subjects participated in a cross-over, double-blind clinical study, using 21-day partial-mouth experimental model of gingivitis. A toothshield was constructed for each volunteer, avoiding the brushing of the 4 experimental posterior teeth in the lower left quadrant. The subjects were randomly assigned initially to use either the placebo gel (control group) or the test gel, containing 10% LS (test group). Results: The clinical results showed statistically significant differences for plaque index (PLI) (p<0.01) between days 0 and 21 in both groups, however only the control group showed statistically significant difference (p<0.01) for the bleeding (IB) and gingival (GI) index within the experimental period of 21 days. On day 21, the test group presented significantly better results than the control group with regard to the GI (p<0.05). Conclusions: The test gel containing 10% LS was effective in the control of gingivitis. PMID:19936516

No data were available on demographic and clinical characteristics of members of fibromyalgia syndrome (FMS) self-help groups in Germany. The study was carried out from November 2010 to April 2011. A set of questionnaires was distributed by the German League Against Rheumatism and the German Fibromyalgia Association to members and to all consecutive FMS patients at nine clinical centres of different levels of care. The set included a self-developed questionnaire on demographic and medical data and on previously and currently used therapies, the patient health questionnaire (PHQ 4) and the fibromyalgia survey questionnaire. Members of FMS self-help groups (N = 1,014) were older and reported a longer duration of chronic widespread pain, less anxiety and depression and a more frequent current use of aerobic exercise, relaxation training and complementary alternative medication than participants not affiliated with FMS self-help groups (N = 630). Membership in FMS self-help groups was associated with less psychological distress and a more frequent use of active self-management strategies.

In this randomized, blinded, multicenter comparison study, 377 infants and children with acute otitis media (AOM) received a 10-day course of an oral suspension of one of the following: cefuroxime axetil (CAE), 30 mg/kg/day; cefaclor (CEC), 40 mg/kg/day; or amoxicillin-clavulanate potassium (AMX-CL), 40 mg/kg/day. Clinical efficacy was determined by pneumatic otoscopy and tympanometric testing 3 to 5, 11 to 14, and 22 to 26 days after the initiation of therapy. There was a statistically significant difference among the three treatment groups with respect to clinical outcome; more patients in the CAE group (62%) than in the CEC group (46%) or the AMX-CL group (52%) had complete resolution of signs and symptoms of AOM (including effusion). Paired comparisons revealed a significant difference in efficacy between CAE and CEC and a nearly significant difference between AMX-CL and CEC. Taste acceptability was highest for CEC and lowest for this formulation of CAE. Significantly more patients in the AMX-CL group than in the CAE or CEC group had a side effect, primarily diarrhea, vomiting, or diaper rash. We conclude that CAE suspension has greater clinical efficacy than CEC and fewer side effects than AMX-CL.

To define regional grey-matter abnormalities in schizophrenia patients with poor insight (Insight(-)), relative to patients with preserved clinical insight (Insight(+)), and healthy controls. Forty stable schizophrenia outpatients (20 Insight(-) and 20 Insight(+)) and 20 healthy controls underwent whole brain magnetic resonance imaging (MRI). Insight in all patients was assessed using the Birchwood Insight Scale (BIS; a self-report measure). The two patient groups were pre-selected to match on most clinical and demographic parameters but, by design, they had markedly distinct BIS scores. Voxel-based morphometry employed in SPM8 was used to examine group differences in grey matter volumes across the whole brain. The three participant groups were comparable in age [F(2,57) = 0.34, P = 0.71] and the patient groups did not differ in age at illness onset [t(38) = 0.87, P = 0.39]. Insight(-) and Insight(+) patient groups also did not differ in symptoms on the Positive and Negative Syndromes scale (PANSS): Positive symptoms [t(38) = 0.58, P = 0.57], negative symptoms [t(38) = 0.61, P = 0.55], general psychopathology [t(38) = 1.30, P = 0.20] and total PANSS scores [t(38) = 0.21, P = 0.84]. The two patient groups, as expected, varied significantly in the level of BIS-assessed insight [t(38) = 12.11, P < 0.001]. MRI results revealed lower fronto-temporal, parahippocampal, occipital and cerebellar grey matter volumes in Insight(-) patients, relative to Insight(+) patients and healthy controls (for all clusters, family-wise error corrected P < 0.05). Insight(+) patient and healthy controls did not differ significantly (P > 0.20) from each other. Our findings demonstrate a clear association between poor clinical insight and smaller fronto-temporal, occipital and cerebellar grey matter volumes in stable long-term schizophrenia patients.

Idiopathic pulmonary fibrosis (IPF) is a chronic, devastating, lung disease, with few therapeutic options. Data are limited with respect to the long-term effect of exercise training (ET) in IPF. This study sought to evaluate the long-term effects of a 12-week ET program on clinical outcomes in IPF patients. Thirty-four IPF patients were randomly allocated to ET or control groups. ET group participated in a 12-week supervised exercise program, while the control group continued with regular medical treatment alone. Exercise capacity, 30 s-chair-stand test for leg strength, dyspnea, and Saint George's Respiratory Questionnaire (SGRQ) for quality of life (QOL) were assessed at baseline and re-evaluated at 11 months from baseline. In addition, at 30-month time point from baseline, the impact of the 12-week intervention was analyzed with respect to survival and cardio-respiratory-related hospitalizations. Thirty-two patients completed the 12-week intervention and 28 patients (14 in each group) were re-evaluated. At 11-month follow-up, no significant differences between the groups and time effect were demonstrated for most outcomes. ET group showed preserved values at the baseline level while the control group showed a trend of deterioration. Only the 30 s-chair-stand test (mean difference 3 stands, p = 0.01) and SGRQ (mean difference -6 units, p = 0.037) were significantly different between the groups. At 30 months, the survival analysis showed three deaths, eight hospitalizations occurred in the control group versus one death, one lung transplantation and seven hospitalizations in the ET group, with no significant differences between groups. At 11-month follow-up, the 12-week ET program showed clinical outcomes were preserved at baseline levels with some maintenance of improvements in leg strength and QOL in the ET group. The control group showed a trend of deterioration in the outcomes. At 30 months, the 12-week ET program did not show benefits in prognosis although the study was underpowered to detect such differences. We suggest including ET as a long-term continued treatment and as a core component of pulmonary rehabilitation programs for IPF patients.

The effect of tilmicosin on the incidence of clinical mastitis and subsequent lamb performance was studied in 9 sheep flocks in Ontario. Ewes were treated randomly with either tilmicosin or placebo approximately one month prior to lambing. Outcome was assessed by comparing rates of clinical mastitis, palpable udder abnormalities, and preweaning (50-day) lamb weights between the 2 treatment groups, while controlling for other important variables. Lambs raised by multiparous ewes treated with tilmicosin were significantly heavier than lambs from placebo-treated multiparous ewes at 50 days. Lambs from tilmicosin-treated ewes were on average 0.52 kg heavier than lambs in the placebo group. There was no difference between treatment groups in the weight of lambs from first parity ewes. Tilmicosin treatment resulted in a 43% decrease in palpable udder abnormalities. Incidence of clinical mastitis did not differ between experimental groups. The administration of tilmicosin prelambing, at the time of routine clostridial disease vaccination, may be a beneficial and convenient way to reduce mastitis infection and improve the preweaning gain of lambs.

It is reasonable to assume that conditions for learning differ between universities and countries. Increased understanding of similarities and differences of student's perceptions of learning environment can be useful in the development of the physiotherapy education as well as of the profession as such. Through international comparisons the benefits and challenges of educational programmes can be made transparent and serve as base for improvement. The objective of this study is to describe and compare physiotherapy students' perceptions of their learning environment in clinical practice in India and Sweden. A questionnaire study was performed, covering physiotherapy students' perceptions of their clinical learning environment, the physiotherapy supervisor within the clinical context, their supervisory relationship and the role of the clinical supervisor at two Universities, Luleå in Sweden and Amity in New Delhi, India. Undergraduate students at two physiotherapy programmes, in New Delhi, India and in Luleå, Sweden participated in the questionnaire study. In general, both groups had high rankings of their perceptions of the clinical learning environment. The Swedish students ranked individual supervision, participation in meetings, the supervisor as a resource, being a part of the team and giving them valuable feedback higher than the Indian group. The supervisory relationship was equally satisfying in groups, providing valuable feedback and acknowledging equality and mutuality in the relationship. The Indian group ranked the supervisor as a colleague, as a support in learning, and that he/she made them feel comfortable in meetings higher than the Swedish group. Both groups had high ratings of the supervisor and the clinical learning context Participation at meetings was higher rated in the Swedish and the supervisor as a support in learning higher rated of the Indian students.

A structured comprehensive curriculum (SCC) that uses simulation-based training (SBT) can improve clinical colonoscopy performance. This curriculum may be enhanced through the application of progressive learning, a training strategy centered on incrementally challenging learners. We aimed to determine whether a progressive learning-based curriculum (PLC) would lead to superior clinical performance compared with an SCC. This was a single-blinded randomized controlled trial conducted at a single academic center. Thirty-seven novice endoscopists were recruited and randomized to either a PLC (n = 18) or to an SCC (n = 19). The PLC comprised 6 hours of SBT, which progressed in complexity and difficulty. The SCC included 6 hours of SBT, with cases of random order of difficulty. Both groups received expert feedback and 4 hours of didactic teaching. Participants were assessed at baseline, immediately after training, and 4 to 6 weeks after training. The primary outcome was participants' performance during their first 2 clinical colonoscopies, as assessed by using the Joint Advisory Group Direct Observation of Procedural Skills assessment tool (JAG DOPS). Secondary outcomes were differences in endoscopic knowledge, technical and communication skills, and global performance in the simulated setting. The PLC group outperformed the SCC group during first and second clinical colonoscopies, measured by JAG DOPS (P < .001). Additionally, the PLC group had superior technical and communication skills and global performance in the simulated setting (P < .05). There were no differences between groups in endoscopic knowledge (P > .05). Our findings demonstrate the superiority of a PLC for endoscopic simulation, compared with an SCC. Challenging trainees progressively is a simple, theory-based approach to simulation whereby the performance of clinical colonoscopies can be improved.

The purpose of this study was to examine the effects of case-base learning (CBL) using video on clinical decision-making and learning motivation. This research was conducted between June 2009 and April 2010 as a nonequivalent control group non-synchronized design. The study population was 44 third year nursing students who enrolled in a college of nursing, A University in Korea. The nursing students were divided into the CBL and the control group. The intervention was the CBL with three cases using video. The controls attended a traditional live lecture on the same topics. With questionnaires objective clinical decision-making, subjective clinical decision-making, and learning motivation were measured before the intervention, and 10 weeks after the intervention. Significant group differences were observed in clinical decision-making and learning motivation. The post-test scores of clinical decision-making in the CBL group were statistically higher than the control group. Learning motivation was also significantly higher in the CBL group than in the control group. These results indicate that CBL using video is effective in enhancing clinical decision-making and motivating students to learn by encouraging self-directed learning and creating more interest and curiosity in learning.

To evaluate the correlation between clinical and salivary microbial parameters during treatment with removable orthodontic appliances with or without use of fluoride mouth rinse. A group of 48 patients completed this randomized, controlled, parallel-group, clinical pilot study. 24 patients of the test group (TG) rinsed after tooth brushing with a fluoride mouth rinse (100 ppm AmF/150 ppm NaF) while 21 patients of the control group (CG) did not. Clinical parameters [Approximal Plaque Index (API), Papillary Bleeding Index (PBI)] as well as levels of salivary mutans streptococci (MS) and lactobacilli (LB) were assessed at baseline and after 3, 6, 9 and 12 months. Compliance was documented by participants. Appliance wear-times were estimated retrospectively by the patients. All participants received the same brushing instructions and were supplied with the same toothbrush/toothpaste. A significant correlation of API values with MS levels (p=0.0003) or with LB levels (p=0.001) was observed. Furthermore, appliance wear-times were significantly associated with API values (p=0.02). The changes of MS or LB levels between beginning and end of the study did not differ significantly between study groups. The changes of the API scores showed slightly different median values (-3.5 in the TG vs. 0 in the CG), the difference, however, was not significant. The results emphasise the need for a careful monitoring of the oral hygiene status in patients with removable orthodontic appliances. Larger controlled clinical trials are necessary to investigate treatment options such as use of supplementary fluoride mouth rinse.

Research has demonstrated an association between parenting stress and child behavior problems, and suggested levels of parenting stress are higher among parents of children at risk for behavior problems, such as those with autism and developmental delay (ASD/DD). The goal of the present study was to conduct a systematic review of parenting stress and child behavior problems among different clinical groups (i.e., ASD/DD, chronic illness, with or at-risk for behavioral and/or mood disorders). We also examined demographic and methodological variables as moderators and differences in overall levels of parenting stress between the clinical groups. This systematic review documents a link between parenting stress and child behavior problems with an emphasis on externalizing behavior. One-hundred thirty-three studies were included for quantitative analysis. Parenting stress was more strongly related to child externalizing (weighted ES r = 0.57, d = 1.39) than internalizing (weighted ES r = 0.37, d = 0.79) problems. Moderation analyses indicated that the association between parenting stress and behavior problems was stronger among studies which had mostly male and clinic-recruited samples. Overall, parenting stress levels were higher for parents of children with ASD/DD compared to parents of children from other clinical groups. Findings document the association between parenting stress and child behavior problems and highlight the importance of assessing parenting stress as part of routine care and throughout behavioral intervention programs, especially for groups of children at high risk for behavior problems, such as children with ASD/DD, in order to identify support for both the parent(s) and child.

Most orthodontists believe that fixed retainers are necessary to maintain ideal dental relationships. However, untoward side effects might result from their long-term placement. The aim of this study was to evaluate the clinical and radiographic effect of two commonly used fixed retainers on the health of the periodontium. Thirty patients were randomly divided into two groups to receive either a fiber-reinforced composite retainer or a spiral wire retainer extended on the lingual surfaces of both maxillary and mandibular arches from canine to canine. Periapical radiographs were obtained from the patients at the time of placement of the retainers and after the 6-month period to assess the radiographic conditions of the periodontium. Clinical examination was carried out at the same two time intervals. Even though there were no significant differences between the two groups of study at the beginning of the trial, there were statistically significant differences after the 6-month follow-up regarding the main outcomes of the study. Nearly all indices showed to deteriorate after 6 months in the fiber-reinforced group, while in the spiral wire group, this was not the case. As for the secondary outcomes, radiographic examination did not reveal any statistically significant differences after 6 months or between the two groups. It can be concluded that spiral wire retainers elicit less detrimental periodontal response in the short-term follow-up compared to fiber-reinforced composite retainers as revealed by the primary outcomes of the study.

Arthroscopic techniques tend to become the gold standard in rotator cuff repair. However, little data are reported in the literature regarding the improvement of postoperative outcomes and re-tear rate relative to conventional open surgery. The aim of this study was to compare clinical outcomes and cuff integrity after arthroscopic versus open cuff repair. We prospectively assessed clinical outcomes and cuff integrity after an arthroscopic or open rotator cuff repair with a minimum follow-up of 12 months. Clinical evaluation was based on Constant score, Simple Shoulder Value (SSV) and American Shoulder and Elbow Score (ASES). Rotator cuff healing was explored with ultrasound. 44 patients in arthroscopic group A (mean age 56-year-old) and 43 in open group O (mean age 61-year-old) fulfilled the inclusion criteria. Tendons were repaired with a single row technique associated with biceps tenodesis and subacromial decompression. All objective clinical scores significantly improved postoperatively in both groups. No statistical difference was identified between group A and O regarding, respectively, Constant score (72 vs 75 points; p = 0.3), ASES score (88 vs 91 points; p = 0.3), and SSV (81 vs 85%). The overall rate of re-tear (Sugaya type IV or V) reached 7 and 9%, respectively, in group A and O (p = 0.8). This study did not prove any difference of arthroscopic over open surgery in case of rotator cuff repair regarding clinical outcome and cuff integrity at 1-year follow-up.

To compare clinical and radiographic results after isolated patellofemoral arthroplasty (PFA) using either a second-generation inlay or onlay trochlear design. The hypothesis was that an inlay design will produce better clinical results and less progression of tibiofemoral osteoarthritis (OA) compared to an onlay design. Fifteen consecutive patients undergoing isolated PFA with an onlay design trochlear component (Journey™ PFJ, Smith & Nephew) were matched with 15 patients after isolated PFA with an inlay design trochlear component (HemiCAP ® Wave, Arthrosurface). Matching criteria were age, gender, body mass index, and follow-up period. An independent observer evaluated patients prospectively, whereas data were compared retrospectively. Clinical outcome was assessed using WOMAC, Lysholm score, and pain VAS. Kellgren-Lawrence grading was used to assess progression of tibiofemoral OA. Conversion to total knee arthroplasty was necessary in one patient within each group, leaving 14 patients per group for final evaluation. The mean follow-up was 26 months in the inlay group and 25 months in the onlay group (n.s.). Both groups displayed significant improvements of all clinical scores (p < 0.05). No significant differences were found between the two groups with regard to the clinical outcome and reoperation rate. No significant progression of tibiofemoral OA was observed in the inlay group, whereas 53 % of the onlay group showed progression of medial and/or lateral tibiofemoral OA (p = 0.009). Isolated PFA using either a second-generation inlay or onlay trochlear component significantly improves functional outcome scores and pain. The theoretical advantages of an inlay design did not result in better clinical outcome scores; however, progression of tibiofemoral OA was significantly less common in patients with an inlay trochlear component. This implant design may therefore improve long-term results and survival rates after isolated PFA. III.

Patients who have developed hemiparesis as a result of a central nervous system lesion, often experience reduced walking capacity and worse gait quality. Although clinically, similar gait patterns have been observed, presently, no clinically driven classification has been validated to group these patients' gait abnormalities at the level of the hip, knee and ankle joints. This study has thus intended to put forward a new gait classification for adult patients with hemiparesis in chronic phase, and to validate its discriminatory capacity. Twenty-six patients with hemiparesis were included in this observational study. Following a clinical examination, a clinical gait analysis, complemented by a video analysis, was performed whereby participants were requested to walk spontaneously on a 10m walkway. A patient's classification was established from clinical examination data and video analysis. This classification was made up of three groups, including two sub-groups, defined with key abnormalities observed whilst walking. Statistical analysis was achieved on the basis of 25 parameters resulting from the clinical gait analysis in order to assess the discriminatory characteristic of the classification as displayed by the walking speed and kinematic parameters. Results revealed that the parameters related to the discriminant criteria of the proposed classification were all significantly different between groups and subgroups. More generally, nearly two thirds of the 25 parameters showed significant differences (p<0.05) between the groups and sub-groups. However, prior to being fully validated, this classification must still be tested on a larger number of patients, and the repeatability of inter-operator measures must be assessed. This classification enables patients to be grouped on the basis of key abnormalities observed whilst walking and has the advantage of being able to be used in clinical routines without necessitating complex apparatus. In the midterm, this classification may allow a decision-tree of therapies to be developed on the basis of the group in which the patient has been categorised.

Our aim was to investigate the effects of urinary incontinence subtypes on women's quality of life (including sexual life) and psychosocial state. The patients, who applied to our clinic from March 2011 to August 2011, were identified and stratified into three groups: those with stress incontinence proved urodynamically (USI), those with urge incontinence (UI), and those with mixed incontinence urge incontinence (UI) proved by urodynamic and clinic evaluation. Scores on the Beck anxiety inventory (BAI), pelvic organ prolapse/urinary incontinence sexual questionnaire (PISQ-12), urogenital distress inventory (UDI-6), and incontinence impact questionnaire (IIQ-7) were compared between the urinary incontinence subtypes. According to urodynamic and clinical examination of 111 women with urinary incontinence, 59 (53%) had USI, 35 (32%) had UI, and 17 (15%) had MI. BAI-scores significantly differed between the USI and UI groups (p=0.030) and between the USI and MI groups (p=0.011) not between the UI and MI groups (p=0.597). UDI-6 scores did not significantly differ between the three groups (p=0.845). IIQ-7 scores significantly differed between the USI and MI groups (p=0.003) and between the UI and MI groups (p=0.006) but not between the USI and UI groups. Patients with USI had significantly lower PISQ-12 scores than those with UI (p=0.015). These differences in the effects of incontinence subtypes should be kept in mind in the evaluation of patients with urinary incontinence. Psychiatric assessment may improve the management of incontinence in women, especially UI and MI. Published by Elsevier Ireland Ltd.

Boric acid (BA) has positive effects on bone tissue. In this study, the effects of BA on fracture healing were evaluated in an animal model. Standard closed femoral shaft fractures were created in 40 male Sprague-Dawley rats under general anesthesia. The rats were allocated into five groups (n = 8 each): group 1, control with no BA; groups 2 and 3, oral BA at doses of 4 and 8 mg/kg/day, respectively; group 4, local BA (8 mg/kg); and group 5, both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally). After closed fracture creation, the fracture line was opened with a mini-incision, and BA was locally administered to the fracture area in groups 4 and 5. In groups 2, 3, and 5, BA was administered by gastric gavage daily until sacrifice. The rats were evaluated by clinical, radiological, and histological examinations. The control group (group 1) significantly differed from the local BA-exposed groups (groups 4 and 5) in the clinical evaluation. Front-rear and lateral radiographs revealed significant differences between the local BA-exposed groups and the control and other groups (p < 0.05). Clinical and radiological evaluations demonstrated adequate agreement between observers. The average histological scores significantly differed across groups (p = 0.007) and were significantly higher in groups 4 and 5 which were the local BA (8 mg/kg) and both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally), respectively, compared to the controls. This study suggests that BA may be useful in fracture healing. Further research is required to demonstrate the most effective local dosage and possible use of BA-coated implants.

The purpose of this study was to determine whether dental students' perceptions regarding six communication patterns for use in pediatric dentistry differed depending on whether they were taught by lecturing or by video-based teaching. Prior to the introduction of interpersonal skills in a clinical course in pediatric dentistry, four consecutive cohorts of students (n=107) in a German dental school were divided equally into two groups. Group one (n=57) was taught by video sequences and group two (n=50) by conventional lecture. Six communication patterns were presented: involvement of the child's toy(s), speaking in positive phrases, mentioning a personal aspect, recalling positive behavior of the patient, addressing fear verbally, and complimenting the patient. Immediately after the presentation, students were asked by means of a questionnaire about their assessment of and intentions regarding the clinical application of the communication patterns presented. After completion of the course, they were asked about the communication patterns that had been used. There were significant differences for three communication patterns in favor of video-based teaching (p<0.05); there were no significant differences regarding the intention for clinical application and the actual clinical application. In this study, students perceived differences between video-based teaching and lecturing regarding ease of use, but they did not seem to benefit from one method over the other regarding clinical application.

Degenerative processes can cause chronic low back pain that occasionally creates impingement of the lumbar dorsal rami, resulting in a clinical syndrome previously described as lumbar dorsal ramus syndrome (LDRS). To evaluate the clinical basis of LDRS by comparing pain, disability, and objective measures of pathophysiology in 3 groups of subjects defined by needle electromyography examination (NEE) findings. Prospective group cohort study with retrospective chart review. Veterans Affairs medical center outpatient clinic. Subjects who had undergone lower limb NEE and lumbar magnetic resonance imaging. A total of 71 subjects' records that met the study criteria were retrospectively reviewed for interventional spine procedures performed and to measure the lumbosacral paraspinal cross-sectional area (PSP CSA); 28 of the 71 subjects underwent further clinical assessment. One-way analysis of variance was performed to evaluate group differences. In the retrospective arm: (1) PSP CSAs measured at 4 lower lumbar disk levels (average of 3 consecutive slices/level) bilaterally and overall left and right lumbar average PSP CSA and (2) the frequency and type of interventional spine procedures performed. In the prospective arm: (1) temporal changes of NEE abnormalities, (2) pain measured using the Visual Analog Scale, (3) Pain Disability Questionnaire responses, and (4) Short Form-36 scores. The right L5 CSA was significantly greater in the group with mechanical low back pain compared with the group with lumbar radicular syndrome (F = 3.3; P < .05). No significant group differences were noted in the number of spine procedures performed. No significant differences in pain or disability scores were found among the groups. NEE findings improved over time predominantly in the LDRS group. LDRS is a diagnosis with identifiable NEE (lumbar multifidus denervation) findings and magnetic resonance imaging findings that may include lower lumbar paraspinal atrophy. NEE (paraspinal denervation) findings in persons with LDRS may change over time, and the clinical relevance of LDRS to pain, functional disability, and treatment response is unclear.

To evaluate spatial access to mammography clinics and to investigate whether relocating clinics can improve global access. To determine whether any change in access is distributed equitably between different social groups. The study was undertaken in Perth, Western Australia in 1996. It was an analysis of travel distances to mammography clinics, comparing distances to the pattern of existing clinics and modelled relocated clinics. The study population was the 151,162 women aged 40-64 years resident in Perth in 1991. Overall travel distances to the existing clinics was reduced by 14% when a GIS system was used to relocate them so as to minimise the travel distance for all women. The travel distance of the most disadvantaged groups fell by 2% and by 24% for the least disadvantaged group. GIS modelling can be used to advantage to evaluate potential locations for screening clinics that improve the access for the target population, however global analysis should be supplemented by analysis of special groups to ensure that no group is disadvantaged by the proposal. If new technology is not used to evaluate the placement of health services, population travel distances may be greater than necessary, with possible impacts on attendance rates.

Self-esteem is essential for clinical judgments. Nursing students in clinical environments should make a bridge between theoretical education and clinical function. This study was aimed to survey the effect of guided questioning in peer groups on nursing students' self-esteem and clinical learning. In this quasi-experimental study, all nursing students in semester 4 (60) were selected. The autumn semester students (n = 28) were chosen as the control group, and the spring semester students (n = 32) as the experimental group. The experimental group underwent the course of cardiac medical surgical training by the Guided Reciprocal Peer Questioning. The control group was trained by lecture. After confirmation of the validity and reliability of tools including Rosenberg Self-esteem Scale and the researcher-made questionnaire, data were collected and analyzed by SPSS version 17.0. There was no significant difference concerning demographic and educational characteristics between the two groups. Mean score differences of self-esteem and learning were not significant before teaching, while they were significantly promoted after teaching in the experimental (P < 0.001) and control (P < 0.05) groups. Promotion in the experimental group was more considerable than in the control group. As revealed by the results, inquiry method, due to its more positive impact on self-esteem and students' learning, can be applied alone or in combination with the other methods. Conducting this study for other students and for theoretical courses is suggested.

Recent studies support several overlapping traits between autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD), assuming the existence of a combined phenotype. The aim of our study was to evaluate the common or distinctive clinical features between ASD and ADHD in order to identify possible different phenotypes that could have a clinical value. We enrolled 181 subjects divided into four diagnostic groups: ADHD group, ASD group, ASD+ADHD group (that met diagnostic criteria for both ASD and ADHD), and control group. Intelligent quotient (IQ), emotional and behavior problems, ADHD symptoms, ASD symptoms, and adaptive behaviors were investigated through the following test: Wechsler Intelligence Scale for Children, Wechsler Preschool and Primary Scale of Intelligence or Leiter International Performances Scale Revised, Child Behavior Checklist, Conners' Rating Scales-Revised, SNAP-IV Rating Scale, the Social Communication Questionnaire, Vineland Adaptive Behavior Scales. The ASD+ADHD group differs from ADHD or ASD in some domains such as lower IQ mean level and a higher autistic symptoms severity. However, the ASD+ADHD group shares inattention and hyperactivity deficit and some emotional and behavior problems with the ADHD group, while it shares adaptive behavior impairment with ASD group. These findings provide a new understanding of clinical manifestation of ASD+ADHD phenotype, they may also inform a novel treatment target. © 2015 The Authors Autism Research published by Wiley Periodicals, Inc. on behalf of International Society for Autism Research.

Several reports have suggested that thyrotoxicosis may induce severe coronary artery spasm (CAS). However, there are few data regarding the differences in clinical characteristics of CAS with and without thyrotoxicosis. The aim of our study is to compare the clinical features of CAS with and without thyrotoxicosis. We evaluated 430 consecutive patients with CAS [patients with thyrotoxicosis (N=32, group I) and those without (N=398, group II)] at a single institute between January 2001 and June 2011. We compared clinical presentations, angiographic findings, and adverse outcomes (a composite outcome of cardiac death, myocardial infarction, or rehospitalization due to cardiac cause) of both groups. There was higher incidence of acute myocardial infarction at initial presentation in group I (15.6 vs. 5.8%, P=0.04). CAS with thyrotoxicosis was more diffuse (59.4 vs. 39.3%, P=0.03), more medically intractable (9.4 vs. 0%, P=0.001), and more frequently involved the left main vessel (25.0 vs.0.8%, P=0.001) than CAS without thyrotoxicosis. During the follow-up period (median 43 months), there were no significant differences between the two groups in terms of the risk of adverse outcomes (hazard ratio for CAS with thyrotoxicosis, 1.029; 95% confidence interval, 0.347-3.054). Clinical and angiographic presentations of CAS with thyrotoxicosis were more severe than CAS without thyrotoxicosis, but clinical outcomes were similar in both groups. Optimal vasodilator therapy is essential for the management of CAS with thyrotoxicosis. Thyroid function test should be mandatory for all patients with CAS.

Panic disorder has been suggested to be divided into the respiratory and non-respiratory subtypes in terms of its clinical presentations. The present study aimed to investigate whether there are any differences in treatment response and clinical characteristics between the respiratory and non-respiratory subtypes of panic disorder patients. Among the 48 patients those who completed the study, 25 panic disorder patients were classified as the respiratory subtype, whereas 23 panic disorder patients were classified as the non-respiratory subtype. All patients were treated with escitalopram or paroxetine for 12 weeks. We measured clinical and psychological characteristics before and after pharmacotherapy using the Panic Disorder Severity Scale (PDSS), Albany Panic and Phobic Questionnaire (APPQ), Anxiety Sensitivity Index-Revised (ASI-R), State-Trait Anxiety Inventory (STAI-T, STAI-S), Hamilton Anxiety Rating Scale (HAM-A), and Hamilton Depression Rating Scale (HAM-D). The prevalence of the agoraphobia was significantly higher in the respiratory group than the non-respiratory group although there were no differences in gender and medication between the two groups. The respiratory group showed higher scores on the fear of respiratory symptoms of the ASI-R. In addition, after pharmacotherapy, the respiratory group showed more improvement in panic symptoms than the non-respiratory group. Panic disorder patients with the respiratory subtype showed more severe clinical presentations, but a greater treatment response to SSRIs than those with non-respiratory subtype. Thus, classification of panic disorder patients as respiratory and non-respiratory subtypes may be useful to predict clinical course and treatment response to SSRIs.

Background The aim of this study was to assess the feasibility of Er: YAG laser in bone cutting for removal of impacted lower third molar teeth and compare its outcomes with that of surgical bur. Materials & methods The study comprised 40 subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters like pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing and complications were compared for both groups. Observation & result Clinical parameters like pain, bleeding and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. Conclusion Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered as an alternative tool to surgical bur, specially in anxious patients. PMID:25737885

Conduct of cancer clinical trials requires coordination and cooperation among research and clinic teams. Diffusion of and confusion about responsibility may occur if team members' perceptions of roles and objectives do not align. These factors are critical to the success of cancer centers but are poorly studied. We developed a survey adapting components of the Adapted Team Climate Inventory, Measure of Team Identification, and Measure of In-Group Bias. Surveys were administered to research and clinic staff at a National Cancer Institute-designated comprehensive cancer center. Data were analyzed using descriptive statistics, t tests, and analyses of variance. Responses were received from 105 staff (clinic, n = 55; research, n = 50; 61% response rate). Compared with clinic staff, research staff identified more strongly with their own group ( P < .01) but less strongly with the overall cancer center ( P = .02). Both clinic staff and research staff viewed their own group's goals as clearer than those of the other group ( P < .01) and felt that members of their groups interacted and shared information within ( P < .01) and across ( P < .01) groups more than the other group did. Research staff perceived daily outcomes as more important than did clinic staff ( P = .05), specifically research-related outcomes ( P = .07). Although there are many similarities between clinic and research teams, we also identified key differences, including perceptions of goal clarity and sharing, understanding and alignment with cancer center goals, and importance of outcomes. Future studies should examine how variation in perceptions and group dynamics between clinic and research teams may impact function and processes of cancer care.

Trans-diagnostic approaches suggest that key cognitive and behavioural processes maintain symptoms across a wide range of mental health disorders. Fatigue is a common clinical feature of attention deficit hyperactivity disorder (ADHD) in adulthood; however, empirical data supporting its prevalence are lacking. This study aimed to collate outcomes from outpatient services to (1) investigate the prevalence of fatigue in adults with ADHD, (2) examine symptoms of ADHD in adults with chronic fatigue syndrome (CFS), and (3) consider secondary clinical characteristics common to both disorder groups. Measures of self-reported fatigue were compared across groups of adults with ADHD (N = 243), CFS (N = 86), and healthy controls (HC) (N = 211) using a between-subjects cross-sectional design. Groups were also compared on secondary clinical measures of functional impairment, mood, anxiety, sleep, self-efficacy, and their beliefs about the acceptability of expressing emotions. The ADHD group were significantly more fatigued than HC with 62% meeting criteria for fatigue caseness. ADHD symptoms were significantly greater in the CFS group than in HC. ADHD and CFS groups did not differ significantly on measures of functional impairment, mood, and self-efficacy. No significant differences were detected on measures of anxiety when items relating to physical restlessness were removed from the analysis. Adults with ADHD experience greater fatigue than HC. Adults with CFS and ADHD share many trans-diagnostic clinical characteristics, including difficulties with low mood, anxiety, and reduced self-efficacy, which impact upon their overall functioning. Further research is required to investigate extraneous factors mediating fatigue severity in these clinical groups. Fatigue is a common clinical feature of attention deficit hyperactivity disorder (ADHD) in adulthood. Evidence-based interventions for chronic fatigue syndrome could be adapted to address fatigue in ADHD in adults. © 2016 The British Psychological Society.

Individuals who are injured in the workplace typically have a greater risk of delayed return to work (RTW) and other poor health outcomes compared to those not injured at work. It is not known whether these differences hold true for mild traumatic brain injuries (MTBI). The present study examined differences associated with workplace and non-workplace MTBI upon intake to a specialty MTBI clinic, their outcomes, and risk factors that influence RTW. Slow-to-recover participants were recruited from consecutive referrals to four outpatient MTBI clinics from March 2015 to February 2017. Two clinics treat Worker's Compensation claimants and two clinics serve patients with non-work related injuries in the publically funded health care system. Of 273 eligible patients, 102 completed an initial study assessment (M age = 41.2 years, SD age = 11.7; 54% women) at an average of 2-3 months post injury. Participants were interviewed about their MTBI and completed a battery of standardized questionnaires and performance validity testing. Outcomes, including RTW, were assessed via telephone follow-up 4-5 months later. Workplace injuries comprised 45.1% of the sample. The workplace MTBI group had a greater proportion of men and lower education levels compared to the non-workplace MTBI group. The two groups had a comparable post-concussion symptom burden and performance validity test failure rate. Workplace MTBI was associated with greater post-traumatic stress symptoms. Fifteen patients (14.7%) were lost to follow-up. There were no workplace/non-workplace MTBI differences in RTW outcome at 6-7 months post injury. Of the entire sample, 42.5% of patients had full RTW, 18.4% had partial RTW, and 39.1% had no RTW. Greater post-concussion symptom burden was most predictive of no RTW at follow-up. There was no evidence that the workplace and non-workplace MTBI groups had different risk factors associated with prolonged work absence. Despite systemic differences in compensation and health care access, the workplace and non-workplace MTBI groups were similar at clinic intake and indistinguishable at follow-up, 6-7 months post injury.

Most evaluations of pay-for-performance (P4P) incentives have focused on large-group practices. Thus, the effect of P4P in small practices, where many US residents receive care, is largely unknown. Furthermore, whether electronic health records (EHRs) with chronic disease management capabilities support small-practice response to P4P has not been studied. To assess the effect of P4P incentives on quality in EHR-enabled small practices in the context of an established quality improvement initiative. A cluster-randomized trial of small (<10 clinicians) primary care clinics in New York City from April 2009 through March 2010. A city program provided all participating clinics with the same EHR software with decision support and patient registry functionalities and quality improvement specialists offering technical assistance. Incentivized clinics were paid for each patient whose care met the performance criteria, but they received higher payments for patients with comorbidities, who had Medicaid insurance, or who were uninsured (maximum payments: $200/patient; $100,000/clinic). Quality reports were given quarterly to both the intervention and control groups. Comparison of differences in performance improvement, from the beginning to the end of the study, between control and intervention clinics for aspirin or antithrombotic prescription, blood pressure control, cholesterol control, and smoking cessation interventions. Mixed-effects logistic regression was used to account for clustering of patients within clinics, with a treatment by time interaction term assessing the statistical significance of the effect of the intervention. Participating clinics (n = 42 for each group) had similar baseline characteristics, with a mean of 4592 (median, 2500) patients at the intervention group clinics and 3042 (median, 2000) at the control group clinics. Intervention clinics had greater adjusted absolute improvement in rates of appropriate antithrombotic prescription (12.0% vs 6.1%, difference: 6.0% [95% CI, 2.2% to 9.7%], P = .001 for interaction term), blood pressure control (no comorbidities: 9.7% vs 4.3%, difference: 5.5% [95% CI, 1.6% to 9.3%], P = .01 for interaction term; with diabetes mellitus: 9.0% vs 1.2%, difference: 7.8% [95% CI, 3.2% to 12.4%], P = .007 for interaction term; with diabetes mellitus or ischemic vascular disease: 9.5% vs 1.7%, difference: 7.8% [95% CI, 3.0% to 12.6%], P = .01 for interaction term), and in smoking cessation interventions (12.4% vs 7.7%, difference: 4.7% [95% CI, -0.3% to 9.6%], P = .02 for interaction term). Intervention clinics performed better on all measures for Medicaid and uninsured patients except cholesterol control, but no differences were statistically significant. Among small EHR-enabled clinics, a P4P incentive program compared with usual care resulted in modest improvements in cardiovascular care processes and outcomes. Because most proposed P4P programs are intended to remain in place more than a year, further research is needed to determine whether this effect increases or decreases over time. clinicaltrials.gov Identifier: NCT00884013.

Although stand-alone cages were advocated to be superior to plate-cage construct (PCC) because of comparable clinical outcomes and fewer plate-related complications, cage dislocation and subsidence were frequently mentioned in multilevel fusion. There are some concerns about whether these issues can be effectively prevented in multilevel anterior cervical discectomy and fusion (ACDF) by stand-alone anchored spacer (SAAS). The aim was to compare clinical outcomes, radiologic parameters, and complications of PCC and SAAS in the treatment of three-level cervical spondylotic myelopathy (CSM). This was a retrospective comparative study. A total of 38 consecutive patients with three-level CSM (ACDF with PCC, 20 patients; ACDF with SAAS, 18 patients) were reviewed. Clinical outcomes were assessed using Japanese Orthopaedic Association and Neck Disability Index. The radiologic evaluations included cervical alignment (CA), segmental angle (SA), postoperative curvature loss (PCL), and incidence of subsidence. All the aforementioned parameters were compared before and after surgery between two groups. Besides, the aforementioned results were also compared between the two groups. The complications were also recorded. The mean follow-up period was 30.3 months. No significant differences were observed in clinical outcomes between the two groups (p>.05). Additionally, no significant differences existed in fusion rate between the two groups. There were significant differences in PCL of SA and CA and correction of SA between the two groups (p<.05). Besides, the incidence of subsidence (9 of 54 levels, 16.7%) was recorded in the SAAS group, and the potential of SAAS to reduce the incidence of postoperative dysphagia was not proven. No other complications were observed in this study. In the surgical treatment of three-level CSM, PCC is superior to SAAS in correction and maintenance of SA and avoiding cage subsidence, although the technique of ACDF with SAAS yielded encouraging clinical outcomes and high fusion rate.

To compare the surgical outcomes 12 months after laparoscopic sacrocolpopexy performed with porcine dermis and the current gold standard of polypropylene mesh. Patients scheduled for laparoscopic sacrocolpopexy were eligible for this randomized controlled trial. Both our clinical research nurse and the patients were blinded as to which material was used. Our primary end point was objective anatomic cure defined as no pelvic organ prolapse quantification (POP-Q) points Stage 2 or greater at any postoperative interval. Our sample size calculation called for 57 patients in each group to achieve 90% power to detect a 23% difference in objective anatomic cure at 12 months (α=0.05). Our secondary end point was clinical cure. Any patient with a POP-Q point greater than zero, or Point C less than or equal to -5, or any complaints of prolapse symptoms whatsoever on Pelvic Floor Distress Inventory-20 or Pelvic Floor Impact Questionnaire, Short Form 7, or reoperation for prolapse were considered "clinical failures"; the rest were "clinical cures." Statistical comparisons were performed using the χ or independent samples t test as appropriate. As expected, there were no preoperative differences between the porcine (n=57) and mesh (n=58) groups. The 12-month objective anatomic cure rates for the porcine and mesh groups were 80.7% and 86.2%, respectively (P=.24), and the "clinical cure" rates for the porcine and mesh groups were 84.2% and 89.7%, respectively (P=.96). Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire, Short Form 7 score improvements were significant for both groups with no differences found between groups. There were no major operative complications. There were similar outcomes in subjective or objective results 12 months after laparoscopic sacrocolpopexy performed with either porcine dermis or polypropylene mesh.

Prostatic artery embolization (PAE) is a safe and efficacious procedure for benign prostatic hyperplasia (BPH), though is technically challenging. We present our experience of technical and clinical outcomes of robotic and manual PAE in patients with BPH. IRB-approved retrospective study of 40 consecutive patients 49-81 years old with moderate or severe grade BPH from May 2014 to July 2015: 20 robotic-assisted PAE (group 1), 20 manual PAE (group 2). Robotic-assisted PAE was performed using the Magellan Robotic System. American Urological Association (AUA-SI) score, cost, technical and clinical success, radiation dose, fluoroscopy, and procedure time were reviewed. Statistical analysis was performed within and between each group using paired t test and one-way analysis of variance respectively, at 1 and 3 months. No significant baseline differences in age and AUA-SI between groups. Technical success was 100% (group 1) and 95% (group 2). One unsuccessful subject from group 2 returned for a successful embolization using robotic assistance. Fluoroscopy and procedural times were similar between groups, with a non-significant lower patient radiation dose in group 1 (30,632.8 mGy/cm 2 vs 35,890.9, p = 0.269). Disposable cost was significantly different between groups with the robotic-assisted PAE incurring a higher cost (group 1 $4530.2; group 2 $1588.5, p < 0.0001). Clinical improvement was significant in both arms at 3 months: group 1 mean change in AUA-SI of 8.3 (p = 0.006), group 2: 9.6 (p < 0.0001). No minor or major complications occurred. Robotic-assisted PAE offers technical success comparable to manual PAE, with similar clinical improvement with an increased cost.

The aim of the study is to assess the feasibility of Drugs Rational Usage Guideline System (DRUGS)-supported clinical pathway (CP) for breast carcinoma, cataract, inguinal hernia and 2-diabetes mellitus whether the application of such a system could improve work efficiency, medical safety, and decrease hospital cost. Four kinds of diseases which included 1773 cases (where 901 cases using paper-based clinical pathways and 872 cases using DRUGS-supported clinical pathways) were selected and their demographic and clinical data were collected. The evaluation criteria were length of stay, preoperative length of stay, hospital cost, antibiotics prescribed during hospitalization, unscheduled surgery, complications and prognosis. The median total LOS was 1 to 3 days shorter in the DRUGS-supported CP group as compared to the Paper-based CP group for all types (p < 0.05). Totel hospital cost decreased significantly in the DRUGS-supported CP group than that in Paper-based CP group. About antibiotics prescribed during hospitalization, there were no statistically differences in the time of initial dose of antibiotic and the duration of administration except the choice of antibiotic categories. The proportion of DRUGS-supported clinical pathway conditions where a broad-spectrum antibiotic was prescribed decreased from 63.6 to 34.5 % (p < 0.01) in the Paper-based group. While after the intervention, the differences were statistically not significant in unscheduled surgery, complications and prognosis. In this study, DRUGS-supported clinical pathway for breast carcinoma, cataract, inguinal hernia, 2-diabetes mellitus was smoothly shifted from a paper-based to an electronic system, and confer benefits at the hospital level.

BACKGROUND: Celiac disease (CD) is a common autoimmune disorder with an increasing prevalence, including in ethnic minorities. OBJECTIVE: To report the frequency of CD diagnosis in ethnic minorities presenting to a Canadian pediatric celiac clinic and to determine whether ethnic differences exist at diagnosis or follow-up. METHODS: Patients with biopsy-proven CD diagnosed at a multidisciplinary celiac clinic between 2008 and 2011 were identified through the clinic database. Data at referral, and six-month and 12-month follow-ups were collected. These included demographics, self-reported ethnicity, symptoms, anthropometrics and laboratory investigations, including serum immunoglobulin antitissue transglutaminase (aTTG). RESULTS: A total of 272 patients were identified; 80% (n=218) were Caucasian (group 1) and 20% (n=54) were other ethnicities. South Asians (group 2) comprised 81% (n=44) of the minority population. No differences in age or sex were found between the two groups. Group 1 patients presented more often with gastrointestinal symptoms (71% versus 43%; P<0.001), while patients in group 2 presented more often with growth concerns (21% versus 68%; P<0.001). At diagnosis, serum aTTG level was consistently lower in group 1 compared with group 2 (367 IU/mL versus 834 IU/mL; P=0.030). Both groups reported symptom improvement at six months and one year. At the end of one year, aTTG level was more likely to be normal in group 1 compared with group 2 (64% versus 29%; P<0.001). CONCLUSION: Although they represent a minority group, South Asian children comprised a significant proportion of CD patients presenting to a Canadian celiac clinic. South Asian children were more likely to present with growth concerns, which has important implications for timely diagnosis in this population. In addition, the apparent delay in normalization of aTTG levels suggests that careful follow-up and culturally focused education supports should be developed for South Asian children with CD.

To define clinical subgroups by cluster analysis in patients with unilateral Meniere disease (MD) and to compare them with the clinical subgroups found in bilateral MD. A cross-sectional study with a two-step cluster analysis. A tertiary referral multicenter study. Nine hundred and eighty-eight adult patients with unilateral MD. best predictors to define clinical subgroups with potential different aetiologies. We established five clusters in unilateral MD. Group 1 is the most frequently found, includes 53% of patients, and it is defined as the sporadic, classic MD without migraine and without autoimmune disorder (AD). Group 2 is found in 8% of patients, and it is defined by hearing loss, which antedates the vertigo episodes by months or years (delayed MD), without migraine or AD in most of cases. Group 3 involves 13% of patients, and it is considered familial MD, while group 4, which includes 15% of patients, is linked to the presence of migraine in all cases. Group 5 is found in 11% of patients and is defined by a comorbid AD. We found significant differences in the distribution of AD in clusters 3, 4 and 5 between patients with uni- and bilateral MD. Cluster analysis defines clinical subgroups in MD, and it extends the phenotype beyond audiovestibular symptoms. This classification will help to improve the phenotyping in MD and facilitate the selection of patients for randomised clinical trials. © 2017 John Wiley & Sons Ltd.

The purpose of this study was to compare the use of an intravitreal injection of infliximab and of dexamethasone combined with vancomycin to treat experimental endophthalmitis induced by Staphylococcus epidermidis. The study was conducted between March 25 and April 13, 2012. Twenty-five six-month-old healthy rabbits were used, each weighing 2.5-3 kg. The rabbits were randomized into five groups with five animals per group. Endophthalmitis was induced by 0.1 mL (103 colony-forming units) S. epidermidis in all groups. In group 1, injection was not implemented after the occurrence of endophthalmitis. In groups 2, 3, and 4, the following intravitreal injections were given 24 h after the occurrence of endophthalmitis: group 2, 0.1 mg/0.1 mL vancomycin; group 3, 1 mg/0.1 mL vancomycin and 1 mg/0.1 mL dexamethasone; and group 4, 1 mg/0.1 mL vancomycin and 2 mg/0.1 mL infliximab. Group 5 was the control/uninfected group. The rabbits were clinically assessed each day for seven days. On day 9, a histopathologic evaluation was performed after enucleation. After a clinical evaluation, no statistically significant difference was found between the vancomycin+infliximab and vancomycin+dexamethasone groups (p>0.05). The difference was significant when both groups were compared with the vancomycin group (p<0.001). After the histopathologic evaluation, no statistically significant difference was found among the three groups (p>0.05). An intravitreal injection of infliximab and of dexamethasone combined with vancomycin have similar clinical and histopathologic effects. To supplement the antibiotic treatment of endophthalmitis, infliximab in a safe dose range can be used as an alternative to dexamethasone to suppress inflammation and prevent ocular damage.

To evaluate the outcome of combined therapy (using intraurethral alprostadil and oral sildenafil) in private and clinic patients with erectile dysfunction, and thus assess predictors of satisfaction. In all, 360 men were treated for erectile dysfunction using single and/or combined therapy, comprising 214 private-practice and 166 clinic patients. Responses were evaluated using the International Index for Erectile Function (IIEF) questionnaire before and after treatment. Serum testosterone levels, education and socio-economic status were also assessed. Group 1a consisted of 33 private patients and Group 1b of 24 clinic patients who tried the maximum dose of intraurethral alprostadil monotherapy initially, followed by the maximum dose of sildenafil monotherapy, and remained dissatisfied. Group 2a consisted of 32 private patients and group 2b of 31 clinic patients who tried the maximum dose of sildenafil monotherapy initially, followed by the maximum dose of alprostadil monotherapy, and were also dissatisfied. These two groups of 65 private and 55 clinic patients then underwent combined therapy. The mean (SD) score for erectile function was 24.1 (2) for combined therapy (a 123% improvement), and 19.8 (1. 8) (83% improvement) and 15.2 (1.6) (41% improvement) for sildenafil and alprostadil monotherapies (P < 0.05 for both patient groups). The men also reported an improvement in their satisfaction with intercourse. However, at 18 months, 60 of the 65 private patients but only 40 of the 55 clinic patients continued with combined therapy; thus, the discontinuation rate was three times greater among clinic than among private patients. Furthermore, the private patients had an overall improvement in the satisfaction score of 128%, compared with 51% for the clinic patients. Although there were no significant differences in erectile function improvement within the two satisfied combined therapy groups, the differences in overall satisfaction and long-term withdrawal rates suggests that other factors beside motivation must be involved for success, e.g. education, persistence, realistic expectations, and certain psychological factors. Combined therapy should be considered for those patients who have a suboptimal response to monotherapy and refuse or are not candidates for surgical options. Generally, those patients with a higher education, greater persistence and more realistic expectations were more satisfied with combined therapy.

Peer assessment and feedback is encouraged to enhance students' learning. The aim of this study was to quantitatively and qualitatively analyse pre-clinical and clinical dental students' written peer feedback provided as part of a continuous, formative and structured peer assessment protocol. A total of 309 Year-2 and Year-5 dental students were invited to participate in a peer assessment and peer feedback protocol. Consenting volunteer students were trained to observe each other whilst working in the skills laboratory (Year-2) and in the dental clinic (Year-5). Subsequently, they followed a structured protocol of peer assessment and peer feedback using specially designed work-based forms during a complete academic year. The content of their written feedback was coded according to the UK General Dental Council domain, sign (positive or negative), specificity (task specific or general), and grouped into themes. A total of 108 participants (40 Year-2 and 68 Year-5) completed 1169 peer assessment work-based forms (516 pre-clinical and 653 clinical); 94% contained written feedback. The large majority (82%) of Year-2 feedback represented the clinical domain, 89% were positive, 77% were task specific, and they were grouped into 14 themes. Year-5 feedback was related mostly to Management and Leadership (37%) and Communication (32%), 64% were positive, 75% task specific, and they were clustered into 24 themes. The content of the feedback showed notable differences between Year-2 and Year-5 students. Senior students focused more on Communication and Management and Leadership skills, whilst juniors were more concerned with clinical skills. Year-5 students provided 13% negative feedback compared to only 2% from Year-2. Regulatory focus theory is discussed to explain these differences. Both groups provided peer feedback on a wide and different range of themes. However, four themes emerged in both groups: efficiency, infection control, time management and working speed. A structured peer assessment framework can be used to guide pre-clinical and clinical students to provide peer feedback focused on different domains, and on contrasting signs and specificities. It can also present an opportunity to complement tutors' feedback. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Evidence that home telemonitoring for patients with chronic heart failure (CHF) offers clinical benefit over usual care is controversial as is evidence of a health economic advantage. Between January 2010 and June 2013, patients with a confirmed diagnosis of CHF were enrolled and randomly assigned to 2 study groups comprising usual care with and without an interactive bi-directional remote monitoring system (Motiva®). The primary endpoint in CardioBBEAT is the Incremental Cost-Effectiveness Ratio (ICER) established by the groups' difference in total cost and in the combined clinical endpoint "days alive and not in hospital nor inpatient care per potential days in study" within the follow-up of 12 months. A total of 621 predominantly male patients were enrolled, whereof 302 patients were assigned to the intervention group and 319 to the control group. Ischemic cardiomyopathy was the leading cause of heart failure. Despite randomization, subjects of the control group were more often in NYHA functional class III-IV, and exhibited peripheral edema and renal dysfunction more often. Additionally, the control and intervention groups differed in heart rhythm disorders. No differences existed regarding risk factor profile, comorbidities, echocardiographic parameters, especially left ventricular and diastolic diameter and ejection fraction, as well as functional test results, medication and quality of life. While the observed baseline differences may well be a play of chance, they are of clinical relevance. Therefore, the statistical analysis plan was extended to include adjusted analyses with respect to the baseline imbalances. CardioBBEAT provides prospective outcome data on both, clinical and health economic impact of home telemonitoring in CHF. The study differs by the use of a high evidence level randomized controlled trial (RCT) design along with actual cost data obtained from health insurance companies. Its results are conducive to informed political and economic decision-making with regard to home telemonitoring solutions as an option for health care. Overall, it contributes to developing advanced health economic evaluation instruments to be deployed within the specific context of the German Health Care System.

Periodontal regeneration can be defined as complete restoration of lost periodontal tissues to their original architecture and function. A variety of treatment modalities have been proposed to achieve it. Plasma rich in growth factors (PRGF) is a concentrated suspension of growth factors that promotes restoration of lost periodontal tissues. The objective of the present study is to assess the effect of PRGF associated with guided tissue regeneration (GTR) versus GTR only in the treatment of intrabony defects (IBDs) in patients with chronic periodontitis (CP). Patients with CP (n = 14) with 42 contralateral 2- and 3-walled defects were randomly assigned to test (PRGF+GTR) and control (GTR alone) treatment groups. Clinical and radiographic assessments performed at baseline and after 6 months were: 1) gingival index (GI), 2) probing depth (PD), 3) clinical attachment level (CAL), 4) radiologic defect depth, and 5) bone fill. Comparison of parameters measured at baseline and after 6 months showed mean PD reduction of 3.37 ± 1.62 mm in the control group (P <0.001) and 4.13 ± 1.59 mm in the test group (P <0.001). There was a significant difference in mean change in CAL (P <0.001) in the control group (5.42 ± 1.99) and the test group (5.99 ± 1.77). Mean change in GI was 1.89 ± 0.32 and 1.68 ± 0.58 in the control group and test group, respectively, and the difference was statistically significant (P <0.001). When compared between groups, clinical parameters did not show any statistically significant variations. Mean radiographic bone fill was 1.06 ± 0.81 and 1.0 ± 0.97 in the control group and test group, respectively. However, the difference was not statistically significant. PRGF with GTR, as well as GTR alone, was effective in improving clinical and radiographic parameters of patients with CP at the 6-month follow-up. There was no additive effect of PRGF when used along with GTR in the treatment of IBDs in patients with CP in terms of both clinical and radiologic outcomes.

Alpha-fetoprotein (AFP) and Des-gamma-carboxyprothrombin (DCP) have been extensively studied as biomarkers for the diagnosis of and prognostication in hepatocellular carcinoma (HCC). However there are only few reports on the clinical characteristics of hepatocellular carcinoma in relation to the combination of the two tumor markers in hepatitis B virus-related HCC. The aim of this study was to investigate the clinical characteristics of HBV-related HCC in relation to different sets of AFP and DCP values. Sixty-two patients with untreated HCC were studied. The positive value of AFP was set at 20 1U/L while DCP positive value was set at 150 mAU/ml. Patients were divided into three groups: Group 1(n=36) with AFP ≥ 20 IU/L and DCP ≥ 150 mAU/ml. Group 2(n=24) with AFP <20 1U/L and DCP ≥ 150 mAU/ml. Group 3 (n=2) with AFP < 20 1U/L and DCP < 150 mAU/ml. There were no patients in group 4 meant for those with AFP ≥ 20 1U/L and DCP < 150 mAU/ml. Clinical and laboratory variables were compared among the groups. Clinical and laboratory variables were comparable among the groups with the exception of gender and values of serum alanine aminotransferase (ALT). Males were significantly more than females among the groups (p<0.03). ALT values were significantly different among the groups (p<0.006). Paired comparisons between the groups showed the mean values of serum ALT were significantly higher in group 2 than in group 1(p<0.003). The mean serum ALT values were also higher in group 2 than in group 3 (p <0.014). There was no significant difference between group 1 and group 3 (P = 0.124). HCC patients who are sero-positive for DCP and sero-negative for AFP have significantly higher levels of serum ALT; serum ALT levels may be of diagnostic importance in AFP-negative, HBV-related HCC patients.

To examine similarities and differences in urine drug test (UDT) results in clinical pain patients and pain subjects participating in pain research studies. An observational study with retrospective chart review and data analysis. We analyzed 1,874 UDT results obtained from 1) clinical pain patients (Clinical Group; n = 1,529) and 2) pain subjects consented to participate in pain research studies (Research Group; n = 345). Since several medications such as opioids used in pain management are drugs of abuse (DOA) and can result in a positive UDT, we specifically identified those cases of positive UDT due to nonprescribed DOA and designated these cases as positive UDT with DOA (PUD). We found that 1) there was a higher rate of PUD in clinical pain patients (41.3%) than in pain research study subjects (14.8%); 2) although subjects in the Research Group were informed ahead of time that UDT will be conducted as a screening test, a substantial number (14.8%) of pain research study subjects still showed PUD; 3) there were different types of DOA between clinical pain patients (cannabinoids as the top DOA) and research study subjects (cocaine as the top DOA); and 4) a common factor associated with PUD was opioid therapy in both Clinical Group and Research Group. These results support previous findings that PUD is a common finding in clinical pain patients, particularly in those prescribed opioid therapy, and we suggest that UDT be used as routine screening testing in pain research studies. © 2015 American Academy of Pain Medicine.

Most diabetic and hypertensive patients, principally the elderly, do not achieve adequate disease control and consume 5%-15% of annual health care budgets. Previous studies verified that pharmaceutical care is useful for achieving adequate disease control in diabetes and hypertension. To evaluate the economic cost and the incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year (QALY) of pharmaceutical care in the management of diabetes and hypertension in elderly patients in a primary public health care system in a developing country. A 36-month randomized controlled clinical trial was performed with 200 patients who were divided into a control group (n = 100) and an intervention group (n = 100). The control group received the usual care offered by the Primary Health Care Unit (medical and nurse consultations). The intervention group received the usual care plus a pharmaceutical care intervention. The intervention and control groups were compared with regard to the direct costs of health services (i.e., general practitioner, specialist, nurse, and pharmacist appointments; emergency room visits; and drug therapy costs) and the ICER per QALY. These evaluations used the health system perspective. No statistically significant difference was found between the intervention and control groups in total direct health care costs ($281.97 ± $49.73 per patient vs. $212.28 ± $43.49 per patient, respectively; P = 0.089); pharmaceutical care added incremental costs of $69.60 (± $7.90) per patient. The ICER per QALY was $53.50 (95% CI = $51.60-$54.00; monetary amounts are given in U.S. dollars). Every clinical parameter evaluated improved for the pharmaceutical care group, whereas these clinical parameters remained unchanged in the usual care group. The difference in differences (DID) tests indicated that for each clinical parameter, the patients in the intervention group improved more from pre to post than the control group (P < 0.001). While pharmaceutical care did not significantly increase total direct health care costs, significantly improved health outcomes were seen. The mean ICER per QALY gained suggests a favorable cost-effectiveness.

The new methods of different administration times for the treatment of primary dysmenorrhea are more widely used clinically; however, no obvious mechanism has been reported. Therefore, an animal model which is closer to clinical evaluation is indispensable. A novel animal experiment with different administration times, based on the mice oestrous cycle, for primary dysmenorrhoea treatment was explored in this study. Mice were randomly divided into two parts (one-cycle and three-cycle part) and each part includes five groups (12 mice per group), namely, Jingqian Zhitong Fang (JQF) 6-day group, JQF last 3-day group, Yuanhu Zhitong tablet group, model control group, and normal control group. According to the one-way ANOVAs, results (writhing reaction, and PGF2α, PGE2, NO, and calcium ions analysis by ELISA) of the JQF cycle group were in accordance with those of JQF last 3-day group. Similarly, results of three-cycle continuous administration were consistent with those of one-cycle treatment. In conclusion, the consistency of the experimental results illustrated that the novel animal model based on mice oestrous cycle with different administration times is more reasonable and feasible and can be used to explore in-depth mechanism of drugs for the treatment of primary dysmenorrhoea in future.

Background Inter-ethnic differences have been reported for many mental health outcomes in the UK, but no systematic review on child mental health has been published. The aim of this review is to compare the population-based prevalence of child mental disorders between ethnic groups in Britain, and relate these findings to ethnic differences in mental health service use. Methods A systematic search of bibliographic databases for population-based and clinic-based studies of children aged 0–19, including all ethnic groups and the main child mental disorders. We synthesised findings by comparing each minority group to the White British study sample. Results 31 population-based and 18 clinic-based studies met the inclusion criteria. Children in the main minority groups have similar or better mental health than White British children for common disorders, but may have higher rates for some less common conditions. The causes of these differences are unclear. There may be unmet need for services among Pakistani and Bangladeshi children. Conclusion Inter-ethnic differences exist but are largely unexplained. Future studies should address the challenges of cross-cultural psychiatry and investigate reasons for inter-ethnic differences. PMID:18655701

Cardiopulmonary bypass (CPB) induces a complex inflammatory response involving an increase in inflammatory cytokines, called postperfusion syndrome. Previous studies demonstrated that adsorption of the serum cytokines can reduce acute inflammation and improve clinical outcomes. In this study, patients were placed on continuous renal replacement therapy (CRRT) with a polymethyl methacrylate (PMMA) membrane hemofilter immediately after the start of an open-heart surgery with CPB and throughout the postoperative course to prevent postperfusion syndrome. The aim of this study was to assess whether continuous CRRT using a PMMA filter (PMMA-CRRT) could affect cytokine expression and improve perioperative outcomes. We designed a randomized controlled trial, which included 19 consecutive adult patients on maintenance dialysis and 7 consecutive adult patients who were not on maintenance dialysis (NHD group). Patients on maintenance dialysis were randomly divided into two groups: Ten patients who received CRRT with a polysulfone membrane hemofilter (PS group) and nine patients who received CRRT with a PMMA membrane (PMMA group). Blood samples were collected from the radial or brachial artery at five different time points. Comparisons between the PS, PMMA, and NHD groups revealed a significant main effect of time on changes in serum IL-6 and IL-8 concentrations (p < 0.01) and an interaction (p < 0.05) between time and group. Plasma IL-6 and IL-8 levels after surgery were significantly lower in the PMMA group than in the PS group, while other cytokines measured in this study were not significantly different. In addition, clinical outcomes were not significantly different between the groups. The continuous use of PMMA-CRRT throughout the perioperative period suppressed serum IL-6 and IL-8 concentrations, although there were no differences in clinical outcomes.

Exposure to biomass smoke is a risk factor for chronic obstructive pulmonary disease (COPD). It is unknown whether COPD caused by biomass smoke has different characteristics to COPD caused by tobacco smoke. To determine clinical differences between these two types of the disease. Retrospective observational study of 499 patients with a diagnosis of COPD due to biomass or tobacco smoke. The clinical variables of both groups were compared. There were 122 subjects (24.4%) in the biomass smoke group and 377 (75.5%) in the tobacco smoke group. In the tobacco group, the percentage of males was higher (91.2% vs 41.8%, P<.0001) and the age was lower (70.6 vs 76.2 years, P<.0001). Body mass index and FEV1% values were higher in the biomass group (29.4±5.7 vs 28.0±5.1, P=.01, and 55.6±15.6 vs 47.1±17.1, P<.0001, respectively). The mixed COPD-asthma phenotype was more common in the biomass group (21.3% vs 5%, P<.0001), although this difference disappeared when corrected for gender. The emphysema phenotype was more common in the tobacco group (45.9% vs 31.9%, P=.009). The prevalence of the chronic bronchitis and exacerbator phenotypes, the comorbidity burden and the rate of hospital admissions were the same in both groups. Differences were observed between COPD caused by biomass and COPD caused by tobacco smoke, although these may be attributed in part to uneven gender distribution between the groups.

Sellar reconstruction with intrasellar packing following endoscopic resection of pituitary macroadenomas remains a subject of clinical and radiological discussion particularly, when an intraoperative cerebrospinal fluid (CSF) leakage is absent. This study was conducted to contribute our experience with sellar reconstruction after a standard endoscopic surgery of pituitary macroadenomas without intraoperative CSF leakage to the ongoing discussion between techniques with and without intrasellar packing. A consecutive series of 47 pituitary macroadenomas undergoing excision via a standard endoscopic endonasal transsphenoidal surgery (EETS) without evident intraoperative CSF leakage were retrospectively evaluated over a 10-months mean follow-up period. According to the sellar reconstruction technique, three groups could be identified: Group A - with no intrasellar packing, Group B - with haemostatic materials packing, and Group C - with abdominal fat packing. Postoperative clinical and radiological assessments of the three groups were documented and analyzed for differences in outcome. Postoperative clinical assessment did not differ significantly between the three groups. In group A, postoperative CSF leakage, sphenoid sinusitis and empty sella syndrome were not observed. However, a significant difference in radiological assessment could be identified; the interpretation of sellar contents in postoperative MRI of group A succeeded earlier and more reliably than in other groups with intrasellar packing. There is no difference in the incidence of postoperative CSF leakage and empty sella syndrome among the various reconstructive techniques with and without intrasellar packing, irrespective of size and extension of the pituitary adenoma. Sellar reconstruction without intrasellar packing following a standard EETS is not inferior to other techniques with packing and even shows more radiological advantages, which made it our preferred technique, at least if no intraoperative CSF leakage is evident.

The aim of this study was to systematically review the effect of permissive underfeeding/trophic feeding on the clinical outcomes of critically ill patients. A systematic review of randomized clinical trials to evaluate the mortality, length of stay, and mechanical ventilation duration in patients randomized to either hypocaloric or full-energy enteral nutrition was performed. Data sources included PubMed and Scopus and the reference lists of the articles retrieved. Two independent reviewers participated in all phases of this systematic review as proposed by the Cochrane Handbook, and the review was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 7 randomized clinical trials that included a total of 1,717 patients were reviewed. Intensive care unit length of stay and mechanical ventilation duration were not statistically different between the intervention and control groups in all randomized clinical trials, and mortality rate was also not different between the groups. In conclusion, hypocaloric enteral nutrition had no significantly different effects on morbidity and mortality in critically ill patients when compared with full-energy nutrition. It is still necessary to determine the safety of this intervention in this group of patients, the optimal amount of energy provided, and the duration of this therapy. © 2018 American Society for Parenteral and Enteral Nutrition.

To measure the effect of an educational intervention on clinical competences for diagnosis and treatment of rheumatic diseases in primary healthcare physicians working in the Guadalajara Metropolitan Area, Jalisco, Mexico. Quasi-experimental study conducted in physicians from two primary health care units. The study was carried out in a 40 physicians sample, 21 in Group "A" (intervention) and 19 in Group "B" (control). The clinical competence for diagnosis and treatment of rheumatic diseases was measured in both groups by means of an instrument previously designed and validated (Kuder-Richardson reliability index =0,94). Clinical competence average score prior to intervention was 47 for Group "A" and 42 for Group "B", while after the intervention it was 72 and 47 respectively, which shows statistically significant differences (Wilcoxon test, p<0,05). Clinical competence for diagnosis and treatment of rheumatic diseases in primary healthcare physicians is low; however, it can be improved by implementing educational interventions based on a constructivist approach.

The aim of this study has been to compare the clinical and radiographic outcome of periodontal intrabony defect treatment by open flap debridement alone or in combination with nanocrystalline hydroxyapatite bone substitute application. Thirty patients diagnosed with advanced periodontits were divided into two groups: the control group (OFD), in which an open flap debridement procedure was performed and the test group (OFD+NHA), in which defects were additionally filled with nanocrystalline hydroxyapatite bone substitute material. Plaque index (PI), gingival index (GI), bleeding on probing (BOP), pocket depth (PD), gingival recession (GR) and clinical attachment level (CAL) were measured prior to, then 6 and 12months following treatment. Radiographic depth and width of defects were also evaluated. There were no differences in any clinical and radiographic parameters between the examined groups prior to treatment. After treatment, BOP, GI, PD, CAL, radiographic depth and width parameter values improved statistically significantly in both groups. The PI value did not change, but the GR value increased significantly after treatment. There were no statistical differences in evaluated parameters between OFD and OFD+NHA groups 6 and 12months after treatment. Within the limits of the study, it can be concluded that the additional use of nanocrystalline hydroxyapatite bone substitute material after open flap procedure does not improve clinical and radiographic treatment outcome.

The present study examined the prevalence and correlates of clinical syndromes in a large group (N = 438) of incarcerated violent offenders, looking at differences between inmates with one and those with more than one clinical syndromes. More than a half of the sample (57%) reported clinically relevant symptoms for at least one clinical syndrome (n = 252), and the majority of them (38%) reported more syndromes in comorbidity (n = 169). Increased severity of clinical conditions (none, one, more than one syndrome) corresponded with significantly greater levels of personality disorder traits, psychological symptoms, dissociation, and negative emotionality, with large effect sizes. After controlling for co-occurrence of personality disorder traits and other symptoms, the presence of more than one comorbid syndrome significantly predicted unique variance in dissociation (positively) and positive emotionality (negatively). The presence of one clinical syndrome significantly and positively predicted negative emotionality. Findings support the possibility that the complexity, and not just the presence, of psychopathology could identify different groups of inmates. PMID:27913716

The aim of this randomized, controlled, clinical study was to compare two surgical techniques with the acellular dermal matrix graft (ADMG) to evaluate which technique could provide better root coverage. Fifteen patients with bilateral Miller Class I gingival recession areas were selected. In each patient, one recession area was randomly assigned to the control group, while the contra-lateral recession area was assigned to the test group. The ADMG was used in both groups. The control group was treated with a broader flap and vertical-releasing incisions, and the test group was treated with the proposed surgical technique, without releasing incisions. The clinical parameters evaluated before the surgeries and after 12 months were: gingival recession height, probing depth, relative clinical attachment level and the width and thickness of keratinized tissue. There were no statistically significant differences between the groups for all parameters at baseline. After 12 months, there was a statistically significant reduction in recession height in both groups, and there was no statistically significant difference between the techniques with regard to root coverage. Both surgical techniques provided significant reduction in gingival recession height after 12 months, and similar results in relation to root coverage.

To validate a theoretical model of encopresis in terms of psychological factors that differentiates children with and without chronic encopresis and to identify scales that demonstrate these differences. Eighty-six children with encopresis were compared to 62 nonsymptomatic children on five psychometric instruments. Differences in the mean scores and the percentages of children falling beyond preselected clinical thresholds were compared across the patient-control groups. Children with encopresis were found to have more anxiety/depression symptoms, family environments with less expressiveness and poorer organization, more attention difficulties, greater social problems, more disruptive behavior, and poorer school performance (ps =.01 < or =.001 on 15/20 subscales). There were no differences in self-esteem. On those subscales where proportionately more encopretic children exceeded clinical thresholds, approximately 20% more of the encopretic children exceeded thresholds than control children. As a group, children with encopresis differ from children without encopresis on a variety of psychological parameters. However, only a minority of children with encopresis demonstrated clinically significant elevations in these parameters. Identification and treatment of such clinical issues may enhance treatment efficacy.

Background Macrophages and plasma cells play a key role in the regulation of innate and adaptive immunity. The aim of this study was to assess the presence of these cells in apical periodontitis and their distribution comparing with clinical and image data. Material and Methods Thirty-three lesions were selected and divided in two groups (17 periapical cysts and 16 periapical granulomas). Immunoreactions using anti-CD68 and anti-CD138 antibodies were carried out; image analysis was performed with an optical microscope and 5 high-power fields from each slide were evaluated leading to an average score of immunoexpression. This mean score was compared between the two groups and correlated with the clinical and image data. Results There was no statistically significant difference (p >0.05) for the mean average score of CD68+ macrophages and CD138+ plasma cells when comparing the two groups (cysts x granulomas) and the specimens included in each specific group. No statistically significant differences (p >0.05) were also observed when comparing the average scores with clinical and image data. Conclusions The presence of CD68+ macrophages and CD138+ plasma cells was similar in periapical cysts and granulomas and the presence of these cells did not correlate with clinical and image data from both groups. Key words:Macrophages, plasma cells, apical periodontitis, periapical granuloma, periapical cyst. PMID:29075406

The use of electrocautery for tissue dissection is becoming increasingly popular, despite the associated risk of poor wound healing and excessive scarring. We conducted this study to compare the wound complications and early and late clinical results resulting from electrocautery versus the scalpel to create a cutaneous flap during thyroidectomy. The subjects of this study were 100 patients, randomized prospectively to either a scalpel group (group S, n = 50) or an electrocautery group (group E, n = 50). Thickness of tissue damage, postoperative thickness of the flap, discomfort in the neck 7 days after surgery, and hypoesthesia and paresthesia in the neck 3 months after surgery were significantly higher in group E than in group S. There were no significant differences in overall postoperative wound complications, postoperative pain, satisfaction with the cosmetic result, or overall outcome of the operation between the groups. Although the incidence of seroma was higher in group E (20%) than in group S (8%), the difference was not significant. Although electrocautery was associated with increased histological tissue damage, postoperative flap edema, discomfort, and other complications in the early stage, the clinical and cosmetic results of flaps made using electrocautery or a scalpel were similar and satisfactory 6 months after surgery.

A randomized, blind, controlled clinical study was conducted with a convenience sample of 24 patients to evaluate the effectiveness of an aluminum gallium arsenide (AlGaAs) infrared laser 808 nm after third molar extraction by the use of infrared thermography technique. Patients were divided into four groups: erupted third molars were extracted from the patients in Group I and Group II, and impacted third molars were extracted from the patients in Group III and Group IV. Group I and Group III received mock laser therapy in which the device was powered off, and Group II and Group IV were exposed to laser light. Postoperative clinical parameters related to the third molar extraction were evaluated; these parameters included pain, trismus and edema. Circulatory patterns were also evaluated by infrared thermography that exhibited local temperature coefficient at different postoperative periods. A slight improvement was observed for swelling, pain and trismus in patients who received laser irradiation, although the differences were not statistically significant (P>0.05). Laser therapy had a significant influence on the local circulation in the area near the temporomandibular joint, as determined by infrared thermography (P<0.05). Laser therapy was able to change the local circulation, although it did not significantly influence swelling, pain or trismus during the postoperative period.

Impairments in acoustically cued repetitive finger movement often emerge at rates near to and above 2Hz in persons with Parkinson's Disease (PD) in which some patients move faster (hastening) and others move slower (bradykinetic). The clinical features impacting this differential performance of repetitive finger movement remain unknown. The purpose of this study was to compare repetitive finger movement performance between the more and less affected side, and the difference in clinical ratings among performance groups. Forty-one participants diagnosed with idiopathic PD completed an acoustically cued repetitive finger movement task while "on" medication. Eighteen participants moved faster, 10 moved slower, and 13 were able to maintain the appropriate rate at rates above 2Hz. Clinical measures of laterality, disease severity, and the UPDRS were obtained. There were no significant differences between the more and less affected sides regardless of performance group. Comparison of disease severity, tremor, and rigidity among performance groups revealed no significant differences. Comparison of posture and postural instability scores revealed that the participants that demonstrated hastening had worse posture and postural instability scores. Consideration of movement rate during the clinical evaluation of repetitive finger movement may provide additional insight into varying disease features in persons with PD.

There has been an increasing number of immigrants to Chile in the last years, especially from South American countries. The phenomenon of immigration and its consequences has been studied by international literature, and different health care needs have been reported for this group as compared with local population. In Chile this phenomenon is poorly studied and HIV prevention campaigns are focused on national population needs. To determine baseline clinical and epidemiological characteristics of the HIV infection in Latin-American immigrants presenting to a referral HIV clinical care centre between the years 2003-2013. Retrospective analysis. Baseline characteristics of Latin-American immigrants at admission to the infectious disease unit were compared to a peered group of Chileans in the same unit. There was an increase in the number of immigrants trough out the observation period. Foreigners presented larger proportion of women (26% vs. 9%) and heterosexual conduct as compared to nationals (37% vs 22%). The majority of immigrants came from Peru (55%) and Colombia (12%). There were significant differences in regards to gender and sexual behavior. This brings up the need to address different prevention strategies with more emphasis in women and heterosexual population in this vulnerable group.

To compare the clinical curative effect of thoracolumbar burst fracture treated by the posterior unilateral approach corpectomy fusion screw-rod fixation and anterior corpectomy bone fusion screw plate fixation. From January 2008 to May 2014,36 cases of thoracolumbar burst fracture underwent operation of decompression, fusion, and internal fixation was retrospective analyzed. Among them, 16 patients were treated through posterior approach as posterior group, including 13 males and 3 females aged from 37 to 62 years old; 9 cases caused by falling injury, 3 cases by traffic accident injury,4 cases by heavy aboved;the injury segment was on T₁₂ in 2 cases, L₁ in 5 cases, L₂ in 7 cases, L₃ in 2 cases; according ASIA grade, 3 cases were grade A, 2 cases were grade B, 2 cases were grade C, 5 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 5 to 15 days. Other 20 patients were treated through anterior-lateral approach as anterior-lateral group, including 15 males and 5 females with age from 27 to 62 years old; 12 cases caused by falling injury, 4 cases by traffic accident injury, 4 cases by heavy aboved; the injury segment was on T₁₂ in 2 cases, L₁, in 7 cases, L₂ in 9 cases, L₃ in 2 cases; for ASIA grade: 4 cases were grade A, 2 cases were grade B, 4 cases were grade C, 6 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 4 to 12 days. The operation time, bleeding during operation and postoperative drainage volume were observed in two groups,and the changes of nerve function of ASIA grade, clinical efficacy,improved degree of thoracic and lumbar lordosis,and bony fusion were compared between two groups. All patients were followed up from 12 to 24 months with an average of (15.8 ± 3.3) months. The operation time, bleeding during operation, and postoperative drainage volume had no significant different between two groups (P > 0.05). As compared with preoperative, ASIA grade of two groups at last follow-up had statistically significantly different (P < 0.01), the neural function of two groups after operation was recovered for different extent. The JOA score of two groups was compared between last follow-up and preoperative, the difference had statistically significant (P < 0.01), the two groups showed good clinical effect. The clinical results of ASIA grade, JOA score and RIS had no significant differences between two groups. All patients of two groups were obtained fusion. Thoracic and lumbar lordosis angle improvement degree had no significant difference between two groups ,it bad significant difference had statistical significance compared with preoperative, the two approaches could effectively restore the spinal sequence. For patients with thoracolumbar burst fracture just treated by anterior decompression and reconstruction of anterior column, according to the degree of operation performer' skill proficiency and the patient' condition to choose, but for patients must performed the spinal canal decompression anterior and posterior, the three column-reconstruction to required anterior-posterior approach, the posterior unilateral approach corpectomy fusion screw-rod fixation obviously shorten operation time, reduce the operation wound, it is worth the clinical promotion.

Patients with osteoarthritis (OA) take a variety of health supplements in an attempt to reduce pain and improve function. The aim of this study was to determine the efficacy of methylsulfonylmethane (MSM) in treating patients with knee OA. This study was a prospective, randomized, double-blind, controlled clinical trial. Forty nine men and women 45-90 (mean 68 ± SD 7.3) years of age with knee OA according to the American College of Rheumatology clinical criteria for OA of the knee and with radiographic confirmed knee OA were enrolled in the study and randomly assigned into 2 groups: One received MSM in doses of 1.125 grams 3 times daily for 12 weeks and the other received a placebo in the same dosing frequency. The primary outcomes were the WOMAC Osteoarthritis Index for pain, stiffness and physical function, the Aggregated Locomotor Function (ALF) test that evaluates each patient's physical function, the SF-36 quality of life health survey and the visual-analogue-scale (VAS) for pain. The secondary outcomes were Knee Society Clinical Rating System for Knee Score (KSKS) and Function Score (KSFS). Patients were assessed at baseline, 6 weeks and 12 weeks. All continuous variables were tested by the Kolmogorov-Smirnov test for Normal distribution. Changes within the groups and differences between the groups were calculated by repeated measures of analysis (ANOVA) with one nested variable. There were significant differences between treatment groups over time in WOMAC physical function (14.6 mm [CI: 4.3, 25.0]; p = 0.04) and in WOMAC total score (15.0 mm [CI: 5.1, 24.9]; p = 0.03). Treatment groups did not differ significantly in WOMAC pain (12.4 mm [CI: 0.0, 24.8]); p = 0.08) or WOMAC stiffness (27.2 mm [CI: 8.2, 46.2]; p = 0.08). There was a non-significant difference in SF-36 total score between treatment groups (11.6 [CI: 1.0, 22.1]; p = 0.54). A significant difference was found between groups in VAS for pain (0.7 s [CI: -0.9, 2.4]; p = 0.05). Secondary outcomes showed non-significant differences between the two groups. Patients with OA of the knee taking MSM for 12 weeks showed an improvement in pain and physical function. These improvements, however, are small and it is yet to be determined if they are of clinical significance. ClinicalTrials.gov: NCT01188213.

2013-01-01

Background This study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features. Results 199 patients with a diagnosed ED completed the Clinical Impairment Assessment (CIA) [Cognitive Behavior Therapy and Eating Disorders, 315–318, 2008] and the Eating Disorders Examination (EDE) [Int J Eat Disord 6:1–8]. Differences between diagnostic groups were examined, as were differences between restrictive and binge-purge subtypes. CIA scores and EDE scores were positively correlated and higher in groups with binge-purge behaviours. CIA scores were not correlated with BMI, illness duration or frequency of bingeing/purging behaviours, except in the binge-purge AN group, where CIA scores negatively correlated with BMI. Conclusions Patients with EDs have poor QoL and impairment increases with illness severity. Patients with binge/purge diagnoses are particularly impaired. It remains unclear which clinical features best predict the degree of impairment experienced by patients with EDs. PMID:24999421

We compared levels of geographic access to prenatal clinics in Brooklyn, NY, between immigrant and US-born mothers and among immigrant groups by country of birth. We used birth data to characterize the spatial distribution of mothers and kernel estimation to measure clinic density within a 2-mile radius of each mother. Results showed that geographic access to clinics differs substantially by country of birth. Certain groups (e.g., Pakistani, Bangladeshi) have relatively poor geographic access despite a high need for prenatal care.

Chronic periodontitis, a destructive inflammatory disorder of the supporting structures of the teeth, is prevalent in patients with diabetes. Limited evidence suggests that periodontal therapy may improve glycemic control. To determine if nonsurgical periodontal treatment reduces levels of glycated hemoglobin (HbA1c) in persons with type 2 diabetes and moderate to advanced chronic periodontitis. The Diabetes and Periodontal Therapy Trial (DPTT), a 6-month, single-masked, multicenter, randomized clinical trial. Participants had type 2 diabetes, were taking stable doses of medications, had HbA1c levels between 7% and less than 9%, and untreated chronic periodontitis. Five hundred fourteen participants were enrolled between November 2009 and March 2012 from diabetes and dental clinics and communities affiliated with 5 academic medical centers. The treatment group (n = 257) received scaling and root planing plus chlorhexidine oral rinse at baseline and supportive periodontal therapy at 3 and 6 months. The control group (n = 257) received no treatment for 6 months. Difference in change in HbA1c level from baseline between groups at 6 months. Secondary outcomes included changes in probing pocket depths, clinical attachment loss, bleeding on probing, gingival index, fasting glucose level, and Homeostasis Model Assessment (HOMA2) score. Enrollment was stopped early because of futility. At 6 months, mean HbA1c levels in the periodontal therapy group increased 0.17% (SD, 1.0), compared with 0.11% (SD, 1.0) in the control group, with no significant difference between groups based on a linear regression model adjusting for clinical site (mean difference, -0.05% [95% CI, -0.23% to 0.12%]; P = .55). Periodontal measures improved in the treatment group compared with the control group at 6 months, with adjusted between-group differences of 0.28 mm (95% CI, 0.18 to 0.37) for probing depth, 0.25 mm (95% CI, 0.14 to 0.36) for clinical attachment loss, 13.1% (95% CI, 8.1% to 18.1%) for bleeding on probing, and 0.27 (95% CI, 0.17 to 0.37) for gingival index (P < .001 for all). Nonsurgical periodontal therapy did not improve glycemic control in patients with type 2 diabetes and moderate to advanced chronic periodontitis. These findings do not support the use of nonsurgical periodontal treatment in patients with diabetes for the purpose of lowering levels of HbA1c. clinicaltrials.gov Identifier: NCT00997178.

To compare the oral health-related quality of life (OHRQoL) of children (8- to 10-year-olds) and preadolescents (11- to 14-year-olds) with different oral conditions and to identify concepts associated with their perceptions of oral health (OH) and overall well being (OWB). A cross-sectional study was conducted with 264 students who were distributed into four groups: caries, with the sum of the decayed, missing and filled teeth in the primary (dmft) and permanent dentitions (DMFT) ≥ 1 (n = 72); malocclusion, with the Dental Aesthetic Index (DAI) ≥ 26 (n = 40); temporomandibular disorders (TMD) with at least one sign and one symptom of TMD (n = 89); control, with dmft/DMFT = 0, DAI < 26 and without signs and symptoms of TMD (n = 63). OHRQoL was measured using Portuguese versions of Child Perceptions Questionnaires (CPQ) for children (CPQ8-10) and preadolescents (CPQ11-14). Differences in CPQ scores and in the frequency of responses to global ratings were assessed using Kruskal-Wallis and chi-square/Fisher's exact tests. Multiple linear regression analyses were used to identify items associated with CPQ and global scores. The OHRQoL of the TMD group was statistically different from controls. The malocclusion group reported more oral symptoms and social impacts compared to controls. The variables associated with CPQ scores varied according to clinical condition. OHRQoL was significantly different between clinical groups and controls for both age groups. However, when comparing clinical groups, TMD and caries differed only for preadolescents. The items associated with higher OHRQoL scores were mainly psychosocial for caries and TMD groups, and physical/functional and psychosocial for children and preadolescents with malocclusions, respectively.

Purpose We performed a comparative analysis of the plasma levels of antithrombin (AT) III, plasminogen, fibrinogen, and D-dimer among patients with and without clinically localized prostate cancer to investigate the clinical significance of the coagulation profile in prostate cancer. Materials and Methods A prospective study was performed in which plasma levels of AT III, plasminogen, fibrinogen, and D-dimer were assessed in patients before they underwent prostate biopsy. According to the results of the biopsy, the patients were categorized into the cancer group or the control group. Levels of the four coagulation factors were then compared between the cancer and control groups. Also, levels of the four coagulation factors were correlated with tumor stage and grade in the cancer group. Results The cancer group had significantly lower levels of AT III activity and higher plasma D-dimer levels than did the control group (p=0.007 and p=0.018, respectively). Within the cancer group, no significant differences were observed in the levels of AT III, plasminogen, fibrinogen, or D-dimer between those with a pathological Gleason score of ≥7 and otherwise. Regarding pathologic stage of prostate cancer, the subjects with organ-confined disease and those with extraprostatic extension of a tumor demonstrated no significant differences in the preoperative levels of the four coagulation factors analyzed. Conclusions Our results suggest that plasma levels of AT III and D-dimer are altered in patients with prostate cancer. Further study is needed to elucidate the underlying mechanism and clinical significances of such a phenomenon among patients with clinically localized prostate cancer. PMID:20414406

The aim of this clinical study was to evaluate the long-term clinical performance of non-carious Class V restorations with and without application of chlorhexidine digluconate to acid-etched dentine. After the approval of the Ethics and Informed Consent Committee, 70 non-carious cervical lesions were selected and randomly assigned into two groups, according to the split mouth design. The control group was restored with a two-step etch-and-rinse adhesive (Adper Single Bond 2) following manufacturer's instructions; whereas in the experimental group 2% chlorhexidine digluconate solution was applied to acid etched dentine for 30s after etching and prior to the adhesive application. All lesions were restored with a nanofilled composite resin (Filtek Supreme XT) and polymerized with a light-curing unit operating at 600mW/cm(2). Clinical performance was recorded after 1 week, 6, 12, and 36 months using modified Ryge/USPHS criteria in terms of retention, marginal discoloration, marginal integrity, post-operative sensitivity, and secondary caries incidence. Data were analyzed using Chi-Square, Fisher's exact test and McNemar tests (α=.05). After 36 months the control group showed a success rate of 88% in comparison to 76% of experimental group; however, no statistically difference between them was found (p=.463). Moreover, no statistical differences were observed between groups in the criteria post-operative sensitivity, marginal discoloration, marginal integrity, and secondary caries incidence between the two groups. The addition of 2% chlorhexidine digluconate conditioning step does not improve the clinical durability of adhesive restorations. Copyright © 2013 Elsevier Ltd. All rights reserved.

Objectives To report the incidence and evaluate the clinical significance of goniolens bacterial contamination in clinical use in dogs with three different usage protocols and one with an added cleaning protocol. Animals Studied and Methods Three groups of twenty dogs undergoing gonioscopy at a private practice in the UK had the goniolenses swabbed for bacteriology culture and identification prior to placement on the cornea. Three protocols of lens use, with 2 different types of goniolens, were studied. One protocol was then repeated with 21 dogs with a lens cleaning protocol prior to storage. Results Low levels of bacterial contamination were found in all 3 initial groups (10-15%). No correlation was found between usage protocol used and rate of contamination and no correlation was found between length of storage between use and contamination. All bacteria cultured were considered naturally occurring commensals for the canine eye and environment. The group with a cleaning protocol had a 4.7% contamination rate. This was not statistically different from the non-cleaning groups. Conclusions The rate of bacterial contamination of goniolenses in clinical practice is low and the bacterial contaminants consist of commensal bacteria, unlikely to be of detriment to the eye. Minimal contamination of the goniolenses was found and this did not appear to be of clinical significance. The introduction of a simple cleaning protocol did not produce a statistically significant reduction in bacterial contamination. © 2017 American College of Veterinary Ophthalmologists.

The relationship of postnatal (postpartum) depression (PND) to episodes of depression occurring at other times is not well understood. Despite a number of studies of clinical presentation, there is little consistency in the literature. We have undertaken within- and between-individual comparisons of the clinical presentation of postnatal (PN) and non-postnatal (NPN) depressive episodes in women with recurrent depression. In a sample of well-characterized, parous women meeting DSM-IV and ICD-10 criteria for recurrent major depressive disorder, the clinical presentation of episodes of major depression with onset within 4 weeks of giving birth (PND group, n=50) were compared with (i) the non-postnatal episodes of women with PND, and (ii) episodes of major depression in parous women who had not experienced episodes of mood disorder in relation to childbirth (NPND group, n=132). In addition, the non-postnatal episodes of the PND group of women were compared with the depressive episodes of the NPND group. The small number of differences found between PN and NPN depressive episodes, such as reduced early morning wakening in postnatal episodes, are likely to be explicable by the context of having a new baby rather than by any difference in the nature of the underlying depression. The results do not point to substantial differences in clinical presentation between episodes of major depression occurring in relation to childbirth and at other times. Other avenues of research are therefore required to demonstrate a specific relationship between childbirth and depression.

There are few studies in occupational therapy that compare the perceptions of supervisors and students regarding quality clinical placement programmes, and those that exist indicate substantial differences in the perceptions held by each group. This pilot study was conducted using a cross-sectional descriptive design, with a single questionnaire distributed to occupational therapy students and clinical supervisors. A total of 40 questionnaires were returned: 17 from students and 23 from clinical supervisors. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics: preparation from the university for their placements; consistency across placement sites; instances of supervisors seeking feedback from students; and the burden associated with the placement-related workload for clinicians. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics DISCUSSION: Different perceptions around preparation from universities and consistency across placement sites relate to the existing roles of each group: students are more aware of university preparation and clinical supervisors are more aware of organisational inconsistencies in their respective usual work environments. The discrepancy in the perceived seeking of feedback from students has also been reported in student debriefing sessions. The burdens perceived by clinical supervisors appear to be influenced by a belief that clinical education is an additional duty rather than a core role. © 2016 John Wiley & Sons Ltd.

We analyzed the effects of the Kampo medicine "Dai-kenchu-to" (DKT) on clinical aspects in colorectal surgery. Total 122 patients who underwent colorectal cancer surgery were divided into a DKT group (n = 53) and a non-DKT group (n = 69). The differences of postoperative course and anti-inflammatory responses between those two groups were analyzed. The 53 out of 59 patients could completely take DKT. In the postoperative course, significant difference was observed in the first flatus day. In the anti-inflammatory effects, differences were observed in the heart rate (HR) of the 3rd POD. In the change between 1st POD and 3rd POD, HR in the DKT group was well controlled compared to the non-DKT group. In the patients who had over 37.5°C of body temperature in 1st POD (n = 53), inflammatory response of the DKT group was reduced compared to the non-DKT group. The DKT might have the favorable influences on postoperative bowel movement and systemic inflammatory reaction, and induce the better postoperative course.

This study aimed to investigate the relationship between persistent human papillomavirus (HPV) infection and cervical lesion. Clinical data of 16,320 patients who visited our clinic between January 2009 and December 2013 were collected. Retrospective analysis was performed to analyze the overall HPV infection and compare the infection rates of different subtypes among different age groups, to reveal the relationship between persistent HPV infection and cervical cytology. The overall prevalence of HPV was 26.54%. The most common genotypes were HPV 52, HPV 16, HPV 58, CP8304, and HPV 53. The highest overall high-risk HPV prevalence was found in women older than 60 years, and the lowest prevalence was found in women between the ages of 30 and 39 years. There was no significant difference in low-risk HPV prevalence among different age groups (p = .693). The HPV clearance rate after 1 year among those with initial positive test was 87.65%. The constituent ratios of high- or low-risk HPV subtypes were not significantly different (p = .545) between nonpersistent-positive and persistent-positive (PP) groups. Conversely, the constituent ratios of singe- or multi-type HPV infection were significantly different (p < .05) between these 2 groups. The most common subtypes in PP group were HPV 16, 52, 58, CP8304, and 33. The occurrence rates of atypical squamous cells of undetermined significance, high-grade squamous intraepithelial lesion, and squamous cell carcinoma in the PP group significantly increased (p < .05). Persistent HPV infections are mainly caused by multiple types of HPV and high-risk HPV. Our region should particularly pay attention to the prevention and treatment of HPV 16, 52, and 58.

Clark and Wells' (1995) cognitive model of social anxiety (CWM) explains the maintenance of social anxiety and has been used as a guide for treatment of Social Anxiety Disorder (SAD). Few studies have examined the components of the model together across different samples. This study had two distinct aims: to test the components of CWM and to examine how the variables of CWM may differ between clinical and non-clinical samples with varying levels of social anxiety. Hypothesized relationships between three groups (i.e. a clinical sample of individuals diagnosed with SAD (ClinS), n = 40; socially anxious students (HSA), n = 40; and, non-anxious students (LSA), n = 40) were investigated. Four out of five CWM variables tested were able to distinguish between highly socially anxious and non-anxious groups after controlling for age and depression. CWM variables are able to distinguish between high and low levels of social anxiety and are uniquely related to social anxiety over depression.

To describe and compare visual function measures of two groups of school age children (6-14 years of age) attending a specialist eyecare practice in Austria; one group referred to the practice from educational assessment centres diagnosed with reading and writing difficulties and the other, a clinical age-matched control group. Retrospective clinical data from one group of subjects with reading difficulties (n = 825) and a clinical control group of subjects (n = 328) were examined.Statistical analysis was performed to determine whether any differences existed between visual function measures from each group (refractive error, visual acuity, binocular status, accommodative function and reading speed and accuracy). Statistical analysis using one way ANOVA demonstrated no differences between the two groups in terms of refractive error and the size or direction of heterophoria at distance (p > 0.05). Using predominately one way ANOVA and chi-square analyses, those subjects in the referred group were statistically more likely to have poorer distance visual acuity, an exophoric deviation at near, a lower amplitude of accommodation, reduced accommodative facility, reduced vergence facility, a reduced near point of convergence, a lower AC/A ratio and a slower reading speed than those in the clinical control group (p < 0.05). This study highlights the high proportions of visual function anomalies in a group of children with reading difficulties in an Austrian population. It confirms the importance of a full assessment of binocular visual status in order to detect and remedy these deficits in order to prevent the visual problems continuing to impact upon educational development.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease that likely includes clinically relevant subgroups. To identify subgroups of COPD in ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints) subjects using cluster analysis and to assess clinically meaningful outcomes of the clusters during 3 years of longitudinal follow-up. Factor analysis was used to reduce 41 variables determined at recruitment in 2,164 patients with COPD to 13 main factors, and the variables with the highest loading were used for cluster analysis. Clusters were evaluated for their relationship with clinically meaningful outcomes during 3 years of follow-up. The relationships among clinical parameters were evaluated within clusters. Five subgroups were distinguished using cross-sectional clinical features. These groups differed regarding outcomes. Cluster A included patients with milder disease and had fewer deaths and hospitalizations. Cluster B had less systemic inflammation at baseline but had notable changes in health status and emphysema extent. Cluster C had many comorbidities, evidence of systemic inflammation, and the highest mortality. Cluster D had low FEV1, severe emphysema, and the highest exacerbation and COPD hospitalization rate. Cluster E was intermediate for most variables and may represent a mixed group that includes further clusters. The relationships among clinical variables within clusters differed from that in the entire COPD population. Cluster analysis using baseline data in ECLIPSE identified five COPD subgroups that differ in outcomes and inflammatory biomarkers and show different relationships between clinical parameters, suggesting the clusters represent clinically and biologically different subtypes of COPD.

'Hidden' symptoms, or subtle cognitive deficits and long-term changes in mood, have been linked to the recreational use of 3, 4-methylenedioxymethamphetamine/MDMA, and are notionally present in non-heavy polydrug users. This study assessed the cognitive functioning and mood profiles of clinically diagnosed drug dependents who had never consumed MDMA, recreational drug users that had previously consumed MDMA, with both groups having not consumed illicit drugs for 6-months, and a control group with limited illicit drug use and no MDMA usage in their past. Cognitive functioning was assessed using the Cognitive Drug Research computerised cognitive assessment system and participants completed the Profile of Mood States and Beck Depression Inventory to assess their current mood and depression. Participants in the clinically diagnosed drug dependent group scored significantly worse on the 'Quality of Working Memory' cognitive factor score than both the MDMA and control group (F (2, 33) = 5.75, p = 0.007). The control and clinical groups also differed on depression scores (U [16] = 13.00, p = 0.016) and Tension/Anxiety scores (U [16] = 16.00, p = 0.034), with the clinical group scoring significantly higher in both cases. The MDMA group did not differ from the control group on the measures of cognition or mood. These results suggest that despite a 6-month prolonged abstinence the cognitive deficits ostensibly caused by 'heavy' usage or the dependence on or abuse of illicit drugs are not reversed by abstinence.

This retrospective study evaluated treatment outcome of cast post and core and Composipost systems after 4 yrs of clinical service. 200 patients were included in the study. They were divided in two groups of 100 endodontically treated teeth restored with a post. Group 1: Composipost systems were luted into root canal following the manufacturer's instructions. Group 2: Cast post and cores were cemented into root canal preparations with a traditional technique. The patients were recalled after 6 months, 1, 2 and 4 yrs and clinical and radiographic examinations were completed. Endodontic and prosthodontic results were recorded. Group 1: 95% of the teeth restored with Composiposts showed clinical success; 3% of these samples were excluded for noncompliance and 2% showed endodontic failure. Group 2: Clinical success was found with 84% of teeth restored with cast post and core. 2% of these samples were excluded for noncompliance, 9% showed root fracture, 2% dislodgment of crown and 3% endodontic failure. Statistical evaluation showed significant differences between Groups 1 and 2 (P < 0.001). The results of this retrospective study indicated that the Composipost system was superior to the conventional cast post and core system after 4 yrs of clinical service.

Emergency department visits for skin infections in the United States have increased with the emergence of methicillin-resistant Staphylococcus aureus (MRSA). For cellulitis without purulent drainage, β-hemolytic streptococci are presumed to be the predominant pathogens. It is unknown if antimicrobial regimens possessing in vitro MRSA activity provide improved outcomes compared with treatments lacking MRSA activity. To determine whether cephalexin plus trimethoprim-sulfamethoxazole yields a higher clinical cure rate of uncomplicated cellulitis than cephalexin alone. Multicenter, double-blind, randomized superiority trial in 5 US emergency departments among outpatients older than 12 years with cellulitis and no wound, purulent drainage, or abscess enrolled from April 2009 through June 2012. All participants had soft tissue ultrasound performed at the time of enrollment to exclude abscess. Final follow-up was August 2012. Cephalexin, 500 mg 4 times daily, plus trimethoprim-sulfamethoxazole, 320 mg/1600 mg twice daily, for 7 days (n = 248 participants) or cephalexin plus placebo for 7 days (n = 248 participants). The primary outcome determined a priori in the per-protocol group was clinical cure, defined as absence of these clinical failure criteria at follow-up visits: fever; increase in erythema (>25%), swelling, or tenderness (days 3-4); no decrease in erythema, swelling, or tenderness (days 8-10); and more than minimal erythema, swelling, or tenderness (days 14-21). A clinically significant difference was defined as greater than 10%. Among 500 randomized participants, 496 (99%) were included in the modified intention-to-treat analysis and 411 (82.2%) in the per-protocol analysis (median age, 40 years [range, 15-78 years]; 58.4% male; 10.9% had diabetes). Median length and width of erythema were 13.0 cm and 10.0 cm. In the per-protocol population, clinical cure occurred in 182 (83.5%) of 218 participants in the cephalexin plus trimethoprim-sulfamethoxazole group vs 165 (85.5%) of 193 in the cephalexin group (difference, -2.0%; 95% CI, -9.7% to 5.7%; P = .50). In the modified intention-to-treat population, clinical cure occurred in 189 (76.2%) of 248 participants in the cephalexin plus trimethoprim-sulfamethoxazole group vs 171 (69.0%) of 248 in the cephalexin group (difference, 7.3%; 95% CI, -1.0% to 15.5%; P = .07). Between-group adverse event rates and secondary outcomes through 7 to 9 weeks, including overnight hospitalization, recurrent skin infections, and similar infection in household contacts, did not differ significantly. Among patients with uncomplicated cellulitis, the use of cephalexin plus trimethoprim-sulfamethoxazole compared to cephalexin alone did not result in higher rates of clinical resolution of cellulitis in the per-protocol analysis. However, because imprecision around the findings in the modified intention-to-treat analysis included a clinically important difference favoring cephalexin plus trimethoprim-sulfamethoxazole, further research may be needed. clinicaltrials.gov Identifier: NCT00729937.

Diagnosis and treatment of infective endocarditis (IE) is still a challenge for physicians. Group of patients with the worst prognosis is treated in Intensive Cardiac Care Unit (ICCU). Etiologic agent can not be identified in a substantial number of patients. The aim of study is to find differences between patients with blood culture negative infective endocarditis (BCNIE) and blood culture positive infective endocarditis (BCPIE) treated in ICCU by comparing their clinical course and laboratory parameters. Retrospective analysis of 30 patients with IE hospitalized in ICCU Swietokrzyskie Cardiac Centre between 2010 and 2016. This group consist of 26 men (86,67%) and 4 women (13,3%). Mean age was 58 years ±13. Most of the cases were new disease, recurrence of the disease was observed in 2 cases (6,7%). 8 patients (26,7%) required artificial ventilation, 11 (36,7%) received inotropes and 6 (20%) vasopresors. In 14 (46,7%) cases blood cultures was negative (BCNIE), the rest of patients (16, 53,3%) was blood cultures - positive infective endocarditis (BCIE). Both of the groups were clinically similar. There were no statistically significant differences in incidence of cardiac implants, localization of bacterial vegetations, administered catecholamines, antibiotic therapy, artificial ventilation, surgical treatment, complication and in-hospital mortality. Incidence of cardiac complications in all of BCNIE cases and in 81,3% cases of BCPIE draws attention, but it is not statistically significant difference (p=0,08). There was statistically significant difference in mean BNP blood concentration (3005,17 ng/ml ±2045,2 vs 1013,42 ng/ml ±1087,6; p=0,01), but there were no statistically significant differences in rest of laboratory parameters. BCNIE group has got higher mean BNP blood concentration than BCPIE group. There were no statistically significant differences between these groups in others laboratory parameters, clinical course and administered antibiotic therapy. In our endemic region major cause of BCNIE seems to be early antibiotic therapy prior to collection of blood samples, but further studies are necessary.

Enamel matrix derivative (EMD) has been shown to promote periodontal wound healing and/or regeneration when applied to tooth root surfaces in soft tissue dehiscence models. In addition, guided tissue regeneration (GTR)-based root coverage using collagen membrane (GTRC) has shown promising results. However, limited information is available regarding how EMD may influence GTRC outcome. Twenty-six patients with Miller's Class I or II gingival recession defects of 2.5 mm were recruited for the study. Subjects were randomly assigned to receive either EMD + collagen (EMDC; test group) or collagen membrane (GTRC; control group). Clinical parameters, including plaque index (PI), gingival index (GI), relative clinical attachment levels (RCAL) to the stent, recession depth (RD), recession width (RW), probing depth (PD), gingival tissue thickness (GTT), and width of keratinized gingiva (KG) were assessed at baseline, and 3 and 6 months after surgery. A repeated measure of analysis of variance (ANOVA) was used to determine differences between treatment groups and time effect. Both treatments (GTRC and EMDC) resulted in a statistically significant decrease in RD and RW between baseline and 6 months (P <0.05). However, no difference was noted between treatment groups. The percent of root coverage after 6 months was 75% for GTRC and 63% for EMDC. Complete 100% root coverage was achieved in five patients in the GTRC group, compared to only one patient in the EMDC group. There was a statistically significant gain (P <0.05) in the clinical attachment level (CAL) between baseline and 6 months in both groups, as reflected on the RCAL data. No other significant differences were noted on other clinical parameters (PD, GTT, KG, GI, and PI). GTR-based root coverage utilizing collagen membrane, with or without enamel matrix derivative, can be successfully used in obtaining gingival recession coverage. The application of EMD during GTRC procedures did not add additional benefit to the final clinical outcome.

We report analytic and consensus processes that produced recommendations for clinical stage groups (cTNM) of esophageal and esophagogastric junction cancer for the AJCC/UICC cancer staging manuals, 8th edition. The Worldwide Esophageal Cancer Collaboration (WECC) provided data on 22,123 clinically staged patients with epithelial esophageal cancers. Risk-adjusted survival for each patient was developed using random survival forest analysis from which (1) data-driven clinical stage groups were identified wherein survival decreased monotonically and was distinctive between and homogeneous within groups and (2) data-driven anatomic clinical stage groups based only on cTNM. The AJCC Upper GI Task Force, by smoothing, simplifying, expanding, and assessing clinical applicability, produced (3) consensus clinical stage groups. Compared with pTNM, cTNM survival was "pinched," with poorer survival for early cStage groups and better survival for advanced ones. Histologic grade was distinctive for data-driven grouping of cT2N0M0 squamous cell carcinoma (SCC) and cT1-2N0M0 adenocarcinoma, but consensus removed it. Grouping was different by histopathologic cell type. For SCC, cN0-1 was distinctive for cT3 but not cT1-2, and consensus removed cT4 subclassification and added subgroups 0, IVA, and IVB. For adenocarcinoma, N0-1 was distinctive for cT1-2 but not cT3-4a, cStage II subgrouping was necessary (T1N1M0 [IIA] and T2N0M0 [IIB]), advanced cancers cT3-4aN0-1M0 plus cT2N1M0 comprised cStage III, and consensus added subgroups 0, IVA, and IVB. Treatment decisions require accurate cStage, which differs from pStage. Understaging and overstaging are problematic, and additional factors, such as grade, may facilitate treatment decisions and prognostication until clinical staging techniques are uniformly applied and improved. © 2016 International Society for Diseases of the Esophagus.

In a prospective study of 807 consecutive women shown to have an apparently normal uterus after hysterosalpingography, hysteroscopy or pelvic ultrasonography prior to IVF or intracytoplasmic sperm injection (ICSI) and embryo transfer, the position and length of the uterine cavity was measured routinely at a pre-treatment mock transfer procedure. The apparent length of the uterine cavity was <7 cm in 128 women (group 1), 7-9 cm in 594 women (group 2) and >9 cm in 85 women (group 3). The uterus was noted to be retroverted in 38. 2% (308) women. The embryo transfer catheter was advanced to 5 mm from the uterine fundus based on the previously determined cavity length in all the embryo transfer procedures at 48 h after oocyte collection. Implantation and clinical pregnancy rates were not significantly different with respect to position of the uterus, difficulties encountered in passage of the catheter, mean age of the women, aetiology or duration of infertility or embryology events. An apparently greater cavity length was seen in older and/or parous women, but the difference was not statistically significant. Although the highest implantation and clinical pregnancy rates were seen in women with a cavity length of 7-9 cm (group 2) the differences were not statistically significant: group 1, 18.9 and 36. 7%; group 2, 21.0 and 46.5%; and group 3, 17.3 and 32.9% respectively. The incidence of ectopic pregnancy per reported clinical pregnancy was highest in group 1 women, being 14.9% (7/47) in comparison with group 2 (1.8%, 5/276) and group 3 (0%, 0/27) (P: < 0.0005), suggesting that the size of the uterus is a critical factor in the aetiology of ectopic pregnancy in IVF/ICSI-embryo transfer.

ABSTRACT Introduction. Clinical researches have shown an increased bone disintegration and lower bone mass in patients with calcium urolithiasis. Goal. The goal of our research was to establish the incidence of osteoporosis in adult patients with calcium urolithiasis, on the basis of measuring mineral bone density, using DEXA method, with a special reflection on age subgroups. Material and methods. Clinical research was prospective and it was implemented at the University Clinical Center of Banja Luka, at the Clinic for Endocrinology, Diabetes and Metabolic Diseases and at the Urology Clinic. Material in this research consisted of patients divided in two groups, a working and a control group. One hundred and twenty (120) patients were included in both these groups, divided in three age subgroups: 20-40, 40-60 and over 60. The working group consisted of the patients with calcium urolithiasis and the control group consisted of patients without calcium urolithiasis. Establishing of mineral bone density at L2-L4 of lumbal spine vertebrae and hip was done for the patients in both these groups, using DEXA method. Results. Analysis of mineral bone density using DEXA method in patients in age groups of working and control groups, as well as in the total sample of working and control groups, have shown that the patients of the working group, over 60, had a decreased mineral bone density (30% of osteopenia and 15% osteoporosis) significantly more expressed when compared to the other two age groups (12.5% in the subgroup 20-40 and 17.5% in the subgroup 40-60), which presents a statistically significant difference (p<0.05). In the control group, when taking into account age groups, osteopenia and osteoporosis were marked in 37.5% and 2.5% in the group of patients over 60, whereas in the youngest population, 5% of osteopenia was found, which presents a statistically significant difference (p<0.05). When observing the total sample of working and control group, there was a statistically significant difference in the working and control group (p<0.01); incidence of osteoporosis in the working group amounted to 7.5% and in the control group it was 0.8%. Conclusion. Urolithiasis and osteoporosis are two multifactorial diseases which are evidently reciprocal. This is why we suggest that educating the population about the risk factors for occurrence of these diseases as well as preventive measures that may contribute to their decrease should begin as early as possible.

The aim of the current study was to collect clinical normative data for the Clinical Impairment Assessment questionnaire (CIA) and the Eating Disorder Examination Questionnaire (EDE-Q) from adult patients with eating disorders (EDs). This study also examined unique contributions of eating disorder (ED) symptoms on levels of ED-related impairment. A sample of 667 patients, 620 females and 47 males, was recruited from six specialist centres across Norway. The majority of the sample (40.3%) was diagnosed with eating disorder not otherwise specified (EDNOS), 34.5% had bulimia nervosa (BN), and 25.2% were diagnosed with anorexia nervosa (AN). There were significant differences for global EDE-Q and CIA scores between females and males. In the female sample, significant differences were found on several EDE-Q sub-scales between the AN and BN group, and between the AN and EDNOS group. No significant differences were found between the diagnostic groups on the CIA. In the male sample, no significant differences were found between diagnostic groups on the EDE-Q or CIA. A multiple regression analysis revealed that 46.8% of the variance in impairment as measured by the CIA was accounted for by ED symptoms. Body mass index, Eating Concern, Shape/Weight Concern, and binge eating served as significant, unique predictors of impairment. The results from the present study contribute to the interpretation of EDE-Q and CIA scores in ED samples.

To examine the effectiveness of a physiotherapy-specific, web-based e-learning platform, "RAP-el," in best-practice management of rheumatoid arthritis (RA) using a single-blind, randomized controlled trial (RCT) and prospective cohort study. Australian-registered physiotherapists were electronically randomized into intervention and control groups. The intervention group accessed RAP-eL over 4 weeks. Change in self-reported confidence in knowledge and skills was compared between groups at the end of the RCT using linear regression conditioned for baseline scores by a blinded assessor, using intent-to-treat analysis. Secondary outcomes included physiotherapists' satisfaction with RA management and responses to RA-relevant clinical statements and practice-relevant vignettes. Retention was evaluated in a cohort study 8 weeks after the RCT. Eighty physiotherapists were randomized into the intervention and 79 into the control groups. Fifty-six and 48, respectively, provided baseline data. Significant between-group differences were observed for change in confidence in knowledge (mean difference 8.51; 95% confidence interval [95% CI] 6.29, 10.73; effect size 1.62) and skills (mean difference 7.26; 95% CI 5.1, 9.4; effect size 1.54), with the intervention group performing better. Satisfaction in ability to manage RA, 4 of the 6 clinical statements, and responses to vignettes demonstrated significant improvement in the intervention group. Although 8-week scores showed declines in most outcomes, their clinical significance remains uncertain. RAP-eL can improve self-reported confidence, likely practice behaviors and satisfaction in physiotherapists' ability to manage people with RA, and improve their clinical knowledge in several areas of best-practice RA management in the short term. © 2015, American College of Rheumatology.

Several studies have described the atypical eating behaviors frequently occurring in children with Autism Spectrum Disorder (ASD), and food selectivity is the most frequent of these problems. The everyday management of mealtime behaviors among children with ASD can have a negative impact on family routines and become a significant stressor for families. However, much remains unknown about why food selectivity is so prevalent among individuals with ASD. The objective of this study was to investigate clinical and behavioral features in individuals with ASD with the aim of identifying distinctive clinical profiles in children with and without food selectivity. A total of 158 children with ASD were enrolled in this study: 79 participants with food selectivity (FS) were age and sex matched with 79 participants without food selectivity (No FS). All participants and their parents completed a battery of psychological tests for a comprehensive evaluation of ASD symptoms, cognitive abilities, adaptive skills, behavioral problems and parental stress level. No statistically significant difference on gastrointestinal symptoms and growth adequacy was found between the FS group and the No FS group. Overall, the FS group showed significantly higher rates of ASD symptoms as compared to the No FS group in the questionnaires completed by parents. Furthermore, parents of the FS group reported significantly higher levels of parental stress and a larger degree of their children's behavioral problems as compared to the No FS group. Finally, there were no differences between the FS and the No FS group on any adaptive skill domain. Our findings suggest that the identification of distinctive clinical and behavioral patterns in children with ASD and food selectivity is a crucial issue for parents and therapists in the daily management.

Clinical handovers are an essential part of the daily care and treatment of hospital patients. We invoked a language and social psychology lens to investigate how different health professional groups discussed the communication problems and strengths they experienced in handovers. We conducted in-depth interviews with three different health professional groups within a large metropolitan hospital. We used Leximancer text analytics software as a tool to analyze the data. Results showed that time was of concern to all groups in both similar and diverse ways. All professionals discussed time management, time pressures, and the difficulties of coordinating different handovers. Each professional group had its own unique perceptions and priorities about handovers. Our findings indicated that health professionals understood what was required for handover improvement but did not have the extra capacity to alter their current environment. Hospital management, with clinicians, need to implement handover schedule processes that prioritize interprofessional representation. PMID:28462291

Black and minority ethnic (BME) groups are known to have higher prevalences of psychotic disorders and are over-represented in western penitentiaries and forensic psychiatric institutions. Research from regular mental healthcare settings suggests that they could show different and more severe psychotic symptoms. Aims To explore ethnic variations in severity of symptomatology of BME and non-BME detainees with psychotic disorders. In this study, 824 patients with psychotic disorders from seven different ethnic groups, imprisoned in a penitentiary psychiatric centre in the Netherlands, were compared on symptom severity and symptom representation using the BPRS-E clinical interview. Data were analysed by means of a multilevel analysis. BME patients with psychotic disorders are over-represented in forensic psychiatry, and symptom profiles of prisoners with psychotic disorders vary by ethnicity. Additionally, severity levels of overall psychopathology differ between ethnic groups: patients with an ethnic majority status show more severe levels of psychopathology compared with BME patients. There are differences in symptom severity and symptom profiles between BME patients and non-BME patients. Disregarding these differences could have an adverse effect on the outcome of the treatment. Possible explanations and clinical impact are discussed. Declaration of interest None.

Canine parvovirus (CPV) infection is a common and severe disease particularly affecting young dogs. The paramunity inducer PIND-ORF is reported to stimulate the innate immune system and, if used as a supplementary medication, might lead to a more rapid improvement in clinical signs in dogs with CPV infection. The aim of this study was to evaluate the efficacy of PIND-ORF in dogs with CPV infection in a prospective, placebo-controlled, double-blinded trial using 38 dogs randomly assigned to two groups. Inclusion criteria were clinical signs consistent with CPV infection and a positive faecal CPV PCR. Dogs received either PIND-ORF (n = 20) or placebo (n = 18) and additional symptomatic treatment. Time to recovery and mortality rate were compared between the two groups. Clinical signs, complete blood counts (CBC), and serum protein and albumin concentrations were evaluated daily during hospitalisation and on day 14. Viral shedding and antibody titres were measured by faecal CPV PCR and serum neutralisation assay. There was no significant difference in time to recovery, clinical signs, blood parameters, duration of virus shedding, and antibody titres between the two groups. The only significant difference was an increase in lymphocyte counts and antibody titres observed in the PIND-ORF group only. Three dogs receiving placebo did not survive, but the mortality rate was not significantly different between groups (P = 0.097). No significant effect of PIND-ORF on recovery and outcome could be demonstrated. Copyright © 2014 Elsevier Ltd. All rights reserved.

Clinical research studies of behavioral variant frontotemporal dementia (bvFTD) often use Alzheimer disease (AD) as a comparison group for control of dementia variables, using tests of cognitive function to match the groups. These two dementia syndromes, however, are very different in clinical manifestations, and the comparable severity of these dementias may not be reflected by commonly used cognitive scales such as the Mini-Mental State Examination (MMSE). We evaluated different measures of dementia severity and symptoms among 20 people with bvFTD compared to 24 with early-onset AD. Despite similar ages, disease-duration, education, and cognitive performance on two tests of cognitive function, the MMSE and the Montreal Cognitive Assessment (MoCA), the bvFTD participants, compared to the AD participants, were significantly more impaired on other measures of disease severity, including function (Functional Assessment Questionnaire (FAQ)), neuropsychiatric symptoms (Neuropsychiatric Inventory (NPI)), and global dementia stage (Clinical Dementia Rating Scales (CDRs)). However, when we adjusted for the frontotemporal lobar degeneration-CDR (FTLD-CDR) in the analyses, the two dementia groups were comparable across all measures despite significant differences on the cognitive scales. We found tests of cognitive functions (MMSE and MoCA) to be insufficient measures for ensuring comparability between bvFTD and AD groups. In clinical studies, the FTLD-CDR, which includes additional language and behavior items, may be a better overall way to match bvFTD and AD groups on dementia severity.

Yam, Felix K.; Adams, Aimee G.; Divine, Holly; Steinke, Douglas; Jones, Mikael D.

Background Evidence suggests that patients with type 2 diabetes (T2DM) suffer from a high rate of “clinical inertia” or “recognition of the problem but failure to act.” Objective The aim of this study is to quantify the rate of clinical inertia between two models of care: Pharmacist-Managed Diabetes Clinic (PMDC) vs. Usual Medical Care (UMC). Methods Patients in a university based medical clinic with type 2 diabetes (T2DM) were analyzed in this retrospective cohort study. Patients were exposed to either PMDC or UMC. The difference in days to intervention in response to suboptimal laboratory values and time to achieve goal hemoglobin A1c (A1c), systolic blood pressure (SBP) and low-density lipoprotein (LDL) was compared in the two models of care. Results A total of 113 patients were included in the analysis of this study, 54 patients were in the PMDC and 59 patients were in the UMC group. Median time (days) to intervention for A1c values >7% was 8 days and 9 days in the PMDC and UMC groups, respectively (p>0.05). In patients with baseline A1c values >8%, median time to achieving A1c<7% was 259 days vs. 403 days in the PMDC and UMC groups, respectively (p<0.05). Median time to goal SBP was 124 days in the PMDC group and 532 days in the UMC group (p<0.05). Median time to goal LDL was 412 days in the PMDC group vs. 506 days in the UMC group (p<0.05). Conclusions Rates of clinical inertia, defined as time to intervention of suboptimal clinical values, did not differ significantly between patients enrolled in a PMDC compared to patients with UMC with respect to A1c, SBP and LDL. Participation in PMDC, however, was associated with achieving goal A1c, SBP, and LDL levels sooner compared to UMC. PMID:24367460

To compare the differences in clinicopathologic features of invasive fungal rhinosinusitis caused by Aspergillus and Mucorales, and to discuss the pathogenesis of tissue injury induced by these two kinds of fungi. The clinical and pathologic features of 19 patients with invasive fungal rhinosinusitis due to Aspergillus (group A) and 16 patients with invasive fungal rhinosinusitis due to Mucorales (group M) were retrospectively reviewed. HE, PAS and GMS stains were performed on all the paraffin-embedded tissues. The diagnosis was confirmed by histologic examination and microbiological culture results. Amongst the group A patients, the clinical course was acute in 4 cases and chronic in 15 cases. Thirteen cases had underlying predisposing conditions, including diabetes (number = 4), malignant tumor (number = 5), history of trauma (number = 1) and radical maxillary sinus surgery (number = 3). Follow-up information was available in 13 patients. Seven of them died, 4 due to fungal encephalopathy and 3 due to underlying diseases. Amongst the group M patients, the clinical course was acute in 14 cases and chronic in 2 cases. Fourteen cases had underlying predisposing conditions, including diabetes (number = 8), malignant tumor (number = 5) and history of wisdom tooth extraction (number = 1). Follow-up information was available in 14 patients. Four of them died of fungal encephalopathy. There was significant difference in clinical onset between the two groups (P = 0.01). There was however no difference in terms of underlying predisposing conditions and disease mortality. Histologically, the microorganisms in group A patients formed fungal masses and attached to the mucosal surface, resulting in necrotic bands (11/19). Epithelioid granulomas were conspicuous but multinucleated giant cells were relatively rare. Deep-seated necrosis, granulomatous inflammation against fungal organisms (3/19) and vasculitis with thrombosis (4/19) were not common. On the other hand, large areas of geographic necrosis involving deep-seated tissue could be seen in group M patients (13/16). Isolated multinucleated giant cells were commonly seen. Granulomatous inflammation against fungal organisms were identified (16/16). Vasculitis and thrombosis were also observed (10/16). The invasiveness of Mucorales is remarkable; and when it causes invasive fungal rhinosinusitis, the clinical course is often acute and large areas of tissue necrosis can be seen. The invasiveness of Aspergillus in tissue is relatively mild. Granulomas are more common and the disease often runs a chronic clinical course. There is however no significant difference in long-term mortality. The pathogenesis may be related to the different components of the fungi.

Systemic lupus erythematosus in the elderly has a different clinical and serologic course from that in young patients. Radiographic findings in patients in whom the diagnosis was made after age 50 were compared with findings in younger patients to see if the radiologic patterns are also different. The only significant radiographic difference between the two groups was that the older group had a greater incidence of soft-tissue swelling of the hands and wrists (p < 0.001). There was no significant difference in osteopenia, erosion, soft-tissue calcification, alignment abnormalities, or intrathoracic findings. Of 24 patients over age 50, two developed lymphomamore » and another developed multiple myeloma. The data agree with clinical observations that there is a higher incidence of arthritis in late-onset lupus, but clinical findings of increased incidence of pleuropericardial disease are not confirmed radiographically. The coincidence of hematologic malignancy with late-onset lupus in this series is noteworthy.« less

Disease management programs for heart failure (HF) effectively reduce HF-related hospitalization rates and mortality. Shared medical appointments (SMAs) offer a cost-effective delivery method for HF disease management programs. However, few studies have evaluated this cost-effective delivery method of HF disease management among Veterans with acute HF. We hypothesized that Veterans who attended a multidisciplinary HF-SMA clinic promoting HF self-management, compared those who only received individual treatment through the HF specialty clinic, would have better 12-month hospitalization outcomes. We completed a retrospective review of the VA electronic health record for HF-SMA clinic appointments (1/1/2012 to 12/31/2013). The multidisciplinary HF-SMA program comprised 4 weekly sessions covering topics including HF disease, HF medications, diet adherence, physical activity, psychological well-being, and stress management. Patients who attended the HF-SMA clinic ( n =54) were compared to patients who were scheduled for an HF-SMA appointment but never attended and were followed only in the HF clinic ( n =37). Outcomes were 12-month HF-related and all-cause hospitalization rates, days in the hospital, and time to first hospitalization. Of 141 patients scheduled for an HF-SMA clinic appointment, 54 met criteria for the HF-SMA clinic group and 37 were included in the HF clinic group. The groups did not significantly differ on any sociodemographic variables. Furthermore, no significant differences were observed between the HF-SMA group and the HF clinic group on demographics or hospitalization outcomes, p >.05 for all comparisons. Our results did not support our hypothesis that offering multidisciplinary, HF-SMAs promoting HF self-management skills, above and beyond the individual disease management care provided in an HF specialty clinic, would improve hospitalization outcomes among Veterans with acute HF. Limitations of the present study and recommendations for HF self-management programs for Veterans are discussed.

Background/Aims Liver stiffness (LS) as assessed by transient elastography (TE) can change longitudinally in patients with chronic hepatitis B (CHB). The aim of this study was to identify the factors that improve LS. Methods Between April 2007 and December 2012, 151 patients with CHB who underwent two TE procedures with an interval of about 2 years were enrolled. Ninety-six of the 151 patients were treated with nucleos(t)ide analogues [the antiviral therapy (+) group], while the remaining 55 patients were not [the antiviral therapy (-) group]. The two groups of patients were stratified according to whether they exhibited an improvement or a deterioration in LS during the study period (defined as an LS change of ≤0 or >0 kPa, respectively, over a 1-year period), and their data were compared. Results No differences were observed between the antiviral therapy (+) and (-) groups with respect to either their clinical characteristics or their initial LS. The observed LS improvement was significantly greater in the antiviral therapy (+) group than in the antiviral therapy (-) group (-3.0 vs. 0.98 kPa, P=0.011). In the antiviral therapy (+) group, the initial LS was higher in the LS improvement group (n=63) than in the LS deterioration group (n=33; 7.9 vs. 4.8 kPa, P<0.001). However, there were no differences in any other clinical characteristic. In the antiviral therapy (-) group, the initial LS was also higher in the LS improvement group (n=29) than in the LS deterioration group (n=26; 8.3 vs. 6.5 kPa, P=0.021), with no differences in any other clinical characteristic. Conclusions A higher initial LS was the only factor associated with LS improvement in patients with CHB in this study. PMID:25834800

The effectiveness of remote patient monitoring and physician care for the treatment of hypertension has not been demonstrated in a randomized clinical trial. The objective of this study was to evaluate the effectiveness of remote patient monitoring with or without remote physician care in reducing office blood pressure in patients with hypertension. A total of 374 hypertensive patients over 20 years of age were randomized into the following three groups: group (1) control, the patients received usual clinical care with home BP monitoring; group (2) the patients were remotely monitored and received office follow-up; and group (3) the patients received remote monitoring without physician office care using the remote monitoring device. For each group, in-office follow-up care was scheduled every 8 weeks for 24 weeks. The primary end point was the difference in sitting SBP at the 24-week follow-up. No difference between the three groups was observed in the primary end point (adjusted mean sitting SBP was as follows: group 1: -8.9±15.5 mm Hg, group 2: -11.3±15.9 mm Hg, group 3: -11.6±19.8 mm Hg, (NS). Significant differences in achieving the target BP at the 24th week of follow-up were observed between groups 1 and 2. The subjects over 55-years old had a significant decrease in the adjusted mean sitting SBP in groups 2 and 3 compared with that of the control group. Remote monitoring alone or remote monitoring coupled with remote physician care was as efficacious as the usual office care for reducing blood pressure with comparable safety and efficacy in hypertensive patients.

A retrospective study was conducted to compare the clinical outcomes of three different types of hardware that are used in mandibular angle fracture fixation. Thirty patients were selected from the hospital database. The patients were categorized into the following groups: group A, in which a single 2.0-mm locking miniplate was used; group B, in which a single rigid 2.3-mm plate was used; and group C, in which a single lag screw was inserted. All patients were followed for 6 months. With regard to intraoperative variables, significant differences were found among the groups in the duration of surgery and cost. Group C had the shortest surgical time, followed by group A and then group B. Two patients, one in group A and one in group B, suffered an occlusal discrepancy after surgery. Of the group A patients, two exhibited wound dehiscence and one had an infection. One patient in group B had an exposed plate. Sensory nerve involvement was noted in three group C patients and one group B patient. The lag screw was associated with the fewest complications and exhibited all of the advantages of plating systems in the treatment of angle fracture. The lag screw involved the least hardware and a short operating time, however the differences were not significant. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons.

To observe the effect of anti-gingivitis IgY toothpaste in control of gingivitis and plaque. The study was a double-blind, randomized, parallel-controlled clinical trail with a total of 100 subjects who were divided into two groups, experimental group and control group. The subjects in experimental group used anti-gingivitis IgY toothpaste to brush twice daily for 3 minutes, and the subjects in control group used none anti-gingivitis IgY toothpaste. The examiner recorded GI, PI and BOP index of all subjects at the baseline, 6-weeks and 12-weeks. SPSS21.0 software package was used for statistical analysis. Twelve weeks later, there were significant differences in GI and BOP between the two groups. Yet no significant difference was found in PI. Anti-gingivitis IgY toothpaste is effective in control of gingivitis.

This paper reports the findings from a 2015 survey of the Commissioning Nurse Leaders' Network. Our aim was to understand how governing body nurses perceive their influence and leadership on clinical commissioning groups. An online survey method was used with a census sample of 238 governing body nurses and nurses working in Commissioning Support Units, who were members of the Commissioning Nurse Leaders' Network. The response rate was 40.7% (n = 97). While most governing body nurses felt confident in their leadership role, this was less so for non-executive governing body nurses. Nurses in Commissioning Support Units were much less positive than governing body nurses about their influence on clinical commissioning groups. Governing body nurses were satisfied with their impact on clinical commissioning groups and so could be said to be leading a nursing agenda but this evidence is limited to their own perceptions and more objective or diverse measures of impact are needed. The purpose of such roles to 'represent nursing, and ensure the patient voice is heard' may be a flawed aspiration, conflating nursing leadership and patient voice. This is the first study to explore explicitly the differences between executive and non-executive governing body nurses and nurses working in commissioning support units. Achieving clinical commissioning groups' goals, including developing and embedding nursing leadership roles in clinical commissioning groups, may be threatened if the contributions of governing body nurses, and other nurses supporting clinical commissioning groups, go unrecognised within the profession, or if general practitioners or other clinical commissioning group executive members dominate decision-making on clinical commissioning groups. © 2018 John Wiley & Sons Ltd.

Internet gaming disorder (IGD) and gambling disorder (GD) share similar clinical characteristics but show different brain functional connectivity patterns. Bupropion is known to be effective for the treatment of patients with IGD and GD. We hypothesized that bupropion may be effective for the treatment of Internet-based gambling disorder (ibGD) and IGD and that the connections between the default mode network (DMN) and cognitive control network (CCN) would be different between ibGD and IGD patients after 12 weeks of bupropion treatment. 16 patients with IGD, 15 patients with ibGD, and 15 healthy subjects were recruited in this study. At baseline and after 12 weeks of bupropion treatment, the clinical symptoms of patients with IGD or ibGD were assessed, and brain activity was evaluated using resting state functional magnetic resonance imaging. After the 12-week bupropion treatment, clinical symptoms, including the severity of IGD or GD, depressive symptoms, attention, and impulsivity improved in both groups. In the IGD group, the functional connectivity (FC) within the posterior DMN as well as the FC between the DMN and the CCN decreased following treatment. Moreover, the FC within the DMN in the IGD group was positively correlated with changes in Young Internet Addiction Scale scores after the bupropion treatment period. In the ibGD group, the FC within the posterior DMN decreased while the FC within the CCN increased after the bupropion treatment period. Moreover, the FC within the CCN in the ibGD group was significantly greater than that in the IGD group. Bupropion was effective in improving clinical symptoms in patients with IGD and ibGD. However, there were differences in the pharmacodynamics between the two groups. After 12 weeks of bupropion treatment, the FC within the DMN as well as between the DMN and CCN decreased in patients with IGD, whereas the FC within the CCN increased in patients with ibGD.

To evaluate the adjunctive clinical effects of a chloramine to non-surgical treatment of peri-implantitis. Eighteen individuals diagnosed with peri-implantitis (clinical signs of inflammation and progressive bone loss) on at least two implants were included. Clinical variables; plaque accumulation (Pl), probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BoP), were recorded at baseline and at 3-month follow-up. Primary clinical efficacy variable was the change in the number of sites with BoP. The implants were randomized into two different treatment groups: test and control. Both implants received supra- and submucosal debridement by ultrasonic instrumentation supplemented with hand instruments. The implants assigned to the test group first received local applications of a chloramine gel (Perisolv ™ ; RLS Global AB, Gothenburg, Sweden) followed by mechanical instrumentation. The oral hygiene was checked at 6 weeks. After 3 months, implants of both groups showed statistically significant reduction (P < 0.001) in the number of BoP-positive sites compared with baseline. The reduction of BoP-positive sites in the test group changed from 0.97 (SD ± 0.12) to 0.38 (SD ± 0.46), and in the control group from 0.97 (SD ± 0.12) to 0.31 (SD ± 0.42). Between-group comparisons revealed no statistically significant differences at baseline and after 3 months, for BoP or any of the other variables. In the present randomized clinical trial of peri-implantitis therapy; non-surgical mechanical debridement with adjunctive use of a chloramine is equally effective in the reduction of mucosal inflammation as conventional non-surgical mechanical debridement up to 3 months. © 2015 John Wiley & Sons A/S.

This study clinically evaluates the treatment outcome of coronally positioned flap (CPF) associated with anorganic bone mineral/peptide-15 (ABM/P-15) in terms of root coverage and gain in clinical attachment level (CAL) and bone height (BH) in isolated Class I gingival recession (GR) defects. Fifteen healthy subjects with bilateral and comparable Miller Class I GR defects were selected. The defects were randomly assigned either to the test group (CPF with ABM/P-15) or to the control group (CPF only). Six months after surgery, a reduction in GR was observed in the test and control groups (2.20 ± 0.54 and 2.40 ± 0.80 mm, respectively; P <0.001) with no intergroup difference (P = 0.33). Complete root coverage was obtained in 10 and 11 defects in the test and control groups, respectively. In the test group 85.56% ± 21.69% and in the control group 90.00% ± 18.42% of the exposed root was covered. Although not clinically significant, a statistically greater increase in the gingival thickness was observed in the test group (0.03 mm; P = 0.01). CAL gain was significant in both groups (test group, 1.93 ± 0.44 mm; control group, 2.13 ± 1.15 mm; P <0.001) with no intergroup difference (P = 0.42). Intergroup and intragroup differences in width of keratinized tissue and BH were not significant (P ≥0.16). In the test group, a positive correlation was observed between BH at baseline and the reduction in GR (r = 0.56; P = 0.03). In isolated Class I GR defects, CPF associated with ABM/P-15 provided no significant difference in root coverage and CAL gain compared to CPF alone. In the ABM/P-15 group, a greater reduction in GR was associated with higher bone level at baseline.

Few recent data are available from formal evaluations of approved new drug applications to address perceptions that racial and ethnic groups are under-represented in clinical trials of new drugs. This study reviews racial and ethnic group participation in clinical trials and race-related labeling for new molecular entities approved during a five-year period by the Food and Drug Administration's (FDA) Center for Drug Evaluation and Research (CDER). This was a retrospective review of FDA medical officers' reviews of clinical trial protocols and product labeling for 185 new molecular entities (NME's) approved by CDER between January 1,1995, and December 31, 1999. Enrollment data were obtained from the reviews and tabulated according to race/ethnicity. The approved product labeling was searched for statements related to product testing in various racial/ethnic groups. All data were compiled and analyzed using Microsoft Access. This study quantifies the participation of racial/ethnic groups in clinical trials by year and therapeutic category. Additionally, the study categorizes labeling based on the types of effects described as related to race/ethnicity. Racial and ethnic groups appear to participate in clinical trials to varying degrees. African Americans participated in trials to the greatest extent; however, their participation steadily declined from 12% in 1995 to 6% in 1999. Among trials known to be conducted only in the U.S., African-American participation is comparable to their representation in the U.S. population. In all cases, participants designated as Hispanic appear to be far below their representation in the population. Some differences in participation for all racial and ethnic groups are seen when comparisons from year-to-year or among drug classes are made. Labeling for 45% (84/185) of the products contained some statement about race, although in only 8% (15/185) were differences related to race described. Fifty percent (50%) of the effects were pharmacokinetic, 39% were efficacy, and 11% were safety. One product label recommended a change in dosage based on racial differences.

The radiological and clinical outcome of surgical treated thoracolumbal fractures were followed up after 6.7 years. The study encompassed 97 patients. The degrees of the bony deformation and the local kyphosis were measured on the lateral view X-ray at 4 different time points: post trauma, after the operation, before implant removal and at the follow up examination. The clinical outcome was evaluated by the Oswestry score. 74 fractures were treated with a fixateur intern and a dorsal fusion by apposition of autologous bone postero-laterally. 23 fractures were fused in a combined dorso-ventral manner by intervertebral fusion with tricortical autologous bone. The lateral X-rays showed a loss of correction up to 48 % in the dorsal fused group and 10 % loss of correction in the combined group. The local kyphosis increased up to 84 % in the dorsal operated group due to degeneration of the injured disk. The clinical Oswestry score showed no significant difference in both groups. The additional ventral surgery should be evaluated carefully.

Schizotypal traits in a non-clinical sample from Hawai'i.

Schiffman, Jason

2004-03-01

Most research investigating schizotypal traits, and linking schizotypal personality disorder (SPD) to later schizophrenia, has used Caucasian samples. The lack of cross-cultural comparisons on SPD trait scales inhibits confidence in generalizing the link between SPD and schizophrenia to non-Caucasian populations. The few studies investigating cross-cultural rates of schizotypal traits in non-clinical samples report mixed findings with respect to cultural variation. This study report rates of schizotypal traits in an ethnically and culturally diverse non-clinical sample (N = 353) in the state of Hawaii using the Schizotypai Personality Disorder Questionnaire-B (SPQ-B). Analyses did not detect significantly elevated rates between ethnic groups on the Cognitive/Perceptual, Disorganized, or Total SPQ Score Scales. Significant differences between Caucasians and Asians, as well as between Caucasians and Mixed Ethnicity on the SPQ-B Interpersonal Scale suggest relatively less shyness and more sociability in the Caucasian group. Generally, findings of no significant differences between ethnic groups on the SPQ-B suggest that rates of schizotypy are similar across ethnic groups in Hawaii.

Regulation of Cognitive Resources During an N-Back Task in Youth-Onset Psychosis and Attention-Deficit/Hyperactivity Disorder (ADHD)

The goals of the current study were to use behavioral and pupillary measures to examine working memory on a spatial n-back task in 8-20-year-olds with youth-onset psychosis or ADHD (Combined subtype) and healthy controls to determine the contribution of different attentional factors to spatial working memory impairments, and to examine if age-related changes in performance differed across groups. Although both clinical groups had lower perceptual sensitivity on both 0- and 1-back, there was no evidence of an impairment in spatial working memory or differential order effects on the 0-back. Instead, results suggest that both clinical groups had difficulty encoding the stimuli. They also appeared to have difficulty maintaining attention and/or readiness to respond, and, to a lesser extent, recruiting resources on a trial-to-trial basis. It is likely that these attentional problems prevented the clinical groups from encoding the stimuli effectively and contributed to their general performance deficits. PMID:19427339

Four-year longitudinal study of mandibular dysfunction in children.

Magnusson, T; Egermark-Eriksson, I; Carlsson, G E

1985-04-01

A longitudinal study of clinical signs and subjective symptoms of mandibular dysfunction was performed with a 4-yr interval in 119 children, now 11 and 15 yr old. The results showed that 66% in both age groups had clinical signs while 62 and 66%, respectively, complained of subjective symptoms. In most cases the signs were mild, but 11% of the 11-yr-olds and 17% of the 15-yr-olds had moderate, or, in a few cases, severe signs of dysfunction. Most of the children with subjective symptoms had their symptoms occasionally but 3% in the younger and 11% in the older age group had frequent symptoms from the masticatory system. When comparisons were made with the findings 4 yr earlier, it was noted that the subjective symptoms had increased in frequency in the younger children, while the clinical signs had increased in both groups. These age differences, as well as the prevalence figures recorded longitudinally, agreed well with previous findings in cross-sectional investigations of different age groups.

Echocardiographic screening is under consideration as a disease control strategy for rheumatic heart disease (RHD). However, clinical outcomes of young people with screening-detected RHD are unknown. We aimed to describe the outcomes for a cohort with screening-detected RHD, in comparison to patients with clinically-diagnosed RHD. A retrospective cohort study included all young people with screening-detected RHD in the Central Division of Fiji in the primary cohort. Screen-negative and clinically-diagnosed comparison groups were matched 1:1 to the primary cohort. Data were collected on mortality, clinical complications and healthcare utilisation from the electronic and paper health records and existing databases. Seventy participants were included in each group. Demographic characteristics of the groups were similar (median age 11years, 69% female, median follow-up 7years). There were nine (12.9%) RHD-related deaths in the clinically-diagnosed group and one (1.4%) in the screening-detected group (Incident Rate Ratio: 9.6, 95% CI 1.3-420.6). Complications of RHD were observed in 39 (55.7%) clinically-diagnosed cases, four (20%) screening-detected cases and one (1.4%) screen-negative case. There were significant differences in the cumulative complication curves of the groups (p<0.001). Rates of admission and surgery were highest in the clinically-diagnosed group, and higher in the screening-detected than screen-negative group. Young people with screening-detected RHD have worse health outcomes than screen-negative cases in Fiji. The prognosis of clinically-diagnosed RHD remains poor, with very high mortality and complication rates. Further studies in other settings will inform RHD screening policy. Comprehensive control strategies are required for disease prevention. Copyright © 2017 Elsevier B.V. All rights reserved.

To study the clinical efficacy of traditional Chinese medicine (TCM) intervention "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") for treating liver failure due to chronic hepatitis B. We designed the study as a randomized controlled clinical trial. Registration number of Chinese Clinical Trial Registry is ChiCTR-TRC-12002961. A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study. Participants were randomly assigned to the following three groups: (1) a modern medicine control group (MMC group, 36 patients); (2) a "tonifying qi and detoxification" ("TQD") group (72 patients); and (3) a "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") group (36 patients). Patients in the MMC group received general internal medicine treatment; patients in the "TQD" group were given a TCM formula "tonifying qi and detoxification" and general internal medicine treatment; patients in the "TTK" group were given a TCM formula of "TTK" and general internal medicine treatment. All participants were treated for 8 wk and then followed at 48 wk following their final treatment. The primary efficacy end point was the patient fatality rate in each group. Measurements of various virological and biochemical indicators served as secondary endpoints. The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups. At the 48-wk post-treatment time point, the patient fatality rates in the MMC, "TQD", and "TTK" groups were 51.61%, 35.38%, and 16.67%, respectively, and the differences between groups were statistically significant (P < 0.05). However, there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups (P > 0.05). Patients in the "TTK" group had significantly higher levels of serum total bilirubin compared to MMC subjects (339.40 μmol/L ± 270.09 μmol/L vs 176.13 μmol/L ± 185.70 μmol/L, P = 0.014). Serum albumin levels were significantly increased in both the "TQD" group and "TTK" group as compared with the MMC group (31.30 g/L ± 4.77 g/L, 30.72 g/L ± 2.89 g/L vs 28.57 g/L ± 4.56 g/L, P < 0.05). There were no significant differences in levels of alanine transaminase among the three groups (P > 0.05). Safety data showed that there was one case of stomachache in the "TQD" group and one case of gastrointestinal side effect in the "TTK" group. Treatment with "TTK" improved the survival rates of patients with liver failure due to chronic hepatitis B. Additionally, liver tissue was regenerated and liver function was restored.

Postpartum weight retention increases lifetime risk of obesity and related morbidity. Few effective interventions exist for multicultural, low-income women. To test whether an internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) for low-income postpartum women could produce greater weight loss than the WIC program alone over 12 months. A 12-month, cluster randomized, assessor-blind, clinical trial enrolling 371 adult postpartum women at 12 clinics in WIC programs from the California central coast between July 2011 and May 2015 with data collection completed in May 2016. Clinics were randomized to the WIC program (standard care group) or the WIC program plus a 12-month primarily internet-based weight loss program (intervention group), including a website with weekly lessons, web diary, instructional videos, computerized feedback, text messages, and monthly face-to-face groups at the WIC clinics. The primary outcome was weight change over 12 months, based on measurements at baseline, 6 months, and 12 months. Secondary outcomes included proportion returning to preconception weight and changes in physical activity and diet. Participants included 371 women (mean age, 28.1 years; Hispanic, 81.6%; mean weight above prepregnancy weight, 7.8 kg; mean months post partum, 5.2 months) randomized to the intervention group (n = 174) or standard care group (n = 197); 89.2% of participants completed the study. The intervention group produced greater mean 12-month weight loss compared with the standard care group (3.2 kg in the intervention group vs 0.9 kg in standard care group, P < .001; difference, 2.3 kg (95% CI, 1.1 to 3.5). More participants in the intervention group than the standard care group returned to preconception weight by 12 months (32.8% in the intervention group vs 18.6% in the standard care group, P < .001; difference, 14.2 percentage points [95% CI, 4.7 to 23.5]). The intervention group and standard care group did not significantly differ in 12-month changes in physical activity (mean [95% CI]: -7.8 min/d [-16.1 to 0.4] in the intervention group vs -7.2 min/d [-14.6 to 0.3] in the standard care group; difference, -0.7 min/d [95% CI, -42.0 to 10.6], P = .76), calorie intake (mean [95% CI]: -298 kcal/d [-423 to -174] in the intervention group vs -144 kcal/d [-257 to -32] in the standard care group; difference, -154 kcal/d [-325 to 17], P = .06), or incidences of injury (16 in the intervention group vs 16 in the standard care group) or low breastmilk supply from baseline to month 6 (21 of 61 participants in the intervention group vs 23 of 72 participants in the standard care group) and from month 6 to 12 (13 of 32 participants in the intervention group vs 14 of 37 participants in the standard care group). Among low-income postpartum women, an internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) compared with the WIC program alone resulted in a statistically significant greater weight loss over 12 months. Further research is needed to determine program and cost-effectiveness as part of the WIC program. clinicaltrials.gov Identifier: NCT01408147.

To compare the clinical outcomes and determine the difference in therapeutic pressure between Automatic positive airway pressure (APAP) and polysomnography manual titration. Fifty patients of obstructive sleep apnea (OSA), moderate to severe cases, were randomized into two groups of intervention: 95-percentile pressure derived from APAP titration and an optimal pressure derived from manual titration. Clinical outcomes were assessed before and after four weeks. The average 95-percentile pressure derived from APAP titration was 11.7 +/- 0.3 cmH2O with median mask leak 1.3 L/min. The average optimal pressure derived from manual titration was 8.2 +/- 0.3 cmH2O. Pearson correlation analysis showed weak positive correlation (r = 0.336, p = 0.017). The Epworth Sleepiness Score (ESS), Quality of life tests: PSQI (Pittsburg Sleep Quality Index), and SF-36 (Medical Outcomes Study 36-Item Short-Form Health Survey) were improved significantly in both groups, but there were no statistical significant differences between groups. An APAP titration is an effective method of pressure determination for conventional CPAP therapy and shows no difference in clinical outcomes comparing the standard titration.

Modern history of short-term group psychotherapy dates back to the late 1950-ies. From then to present day, this psychotherapeutic method has been used in various forms, from dynamic-oriented to cognitive behavioural psychotherapies. Although it has always been considered rather controversial, due its cost-effectiveness, it has been capturing more and more popularity. This paper presents the specificities of first session short-term psychotherapy psychodrama group through session work with two examined groups: a group of 20 adult women who suffer from mild or moderate forms of unipolar depression and a group of 20 students of the School of Medicine in Zagreb without any psychiatric symptomatology. The results indicate the high importance of having structure in first psychodrama session, of relating it with the previously thoroughly conducted, initial, clinical, interviews, and of the clarity and focus in terms of determining the goals of therapy, especially in a clinical context. This study also confirmed assumptions regarding the need for different approaches of warming-up in psychodrama, both in the clinical and in non-clinical samples. A psychodrama psychotherapist should have good time managing skills and capability to convert the time available into an opportunity for directly boosting the group energy and work on therapeutic alliance.

The present study aimed to investigate the association of cholinesterase activity with trypanosomosis in buffaloes. Thirty-three clinical cases of trypanosomosis in water buffaloes, found positive for trypomastigotes of T. evansi on blood smear examination, were divided into two groups based on clinical manifestations. Twenty diseased buffaloes revealing only common clinical signs were allocated to Group I, while the remaining 13 buffaloes showing common clinical manifestations along with neurological disturbances were allocated to Group II. Twelve clinically healthy buffaloes, free from any haemoprotozoa infection, were kept as healthy control (Group III). Blood samples were collected from buffaloes of all three groups to determine serum cholinesterase activity. Compared to buffaloes of healthy control group, cholinesterase activity in T. evansi-infected buffaloes of Group I and II was significantly (P<0.001) lower. However, no significant difference was observed in cholinesterase activity between the T. evansi-infected buffaloes exhibiting neurological disorders and no neurological disorders. Summing up, reduced cholinesterase activity seems to be associated with the pathogenesis of natural T. evansi infection and its clinical manifestations in buffaloes possibly by evading immune response. Further studies are warranted on association of cholinesterase activity in T. evansi-infected buffaloes with neurological disorders. Copyright © 2016 Elsevier B.V. All rights reserved.

Crotaline snakebites (Protobothrops mucrosquamatus and Trimeresurus stejnegeri) are a common medical emergency in Taiwan that can be effectively treated by a bivalent F(ab)2 antivenom. We investigated the differences in the clinical outcomes of patients who received different therapeutic regimens of antivenom in a medical center where clinical toxicologists followed the poison control center (PCC) guidelines (medical group) and surgeons did not (surgical group). The medical records of inpatients with crotaline snakebites between 1991 and 2005 were reviewed and information on demographics, treatments, adverse effects of antivenom, and complications was abstracted and analyzed. A total of 179 patients (90 medical, 89 surgical) were eligible for study. There was no significant intergroup difference in baseline characteristics except that the dose of antivenom and the probability of antibiotic use were both higher in the surgical group (5.9 +/- 4.2 vials vs. 2.7 +/- 1.6 vials; 93% vs. 60%). Multiple logistic regression adjusting for age, gender, calendar year of envenomation, severity of envenomation, and antibiotic use did not disclose evidence of any difference in various clinical outcomes between medical and surgical patients. The lower dose of antivenom recommended by the PCC may be as effective and safe as the higher dose used in the surgical group for the treatment of crotaline snakebites.

The aim of this study was to compare periorbital edema and ecchymosis seen after closed (endonasal) and open (external) septorhinoplasty (SRP). In total, 50 patients undergoing hump extraction and osteotomies were allocated to 2 groups. Group 1 consisted of 25 patients who underwent closed SRP. Group 2 consisted of 25 patients who underwent open SRP. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on the first, third, and seventh postoperative days using a scale of 0 to 4 by the first author. There was no statistically significant difference between the groups in terms of age, sex, or operation time. No significant difference was observed clinically or statistically in the scores of periorbital edema or ecchymosis between groups 1 and 2 on the first, third, and seventh postoperative days (P > 0.05). The authors observed no clinically or statistically significant difference in comparing periorbital edema and ecchymosis seen after closed and open SRP.

AIMS--This study was designed to compare suture needle drainage (SND) with argon laser drainage (ALD) of subretinal fluid. METHODS--A prospective, randomised, controlled, clinical trial was carried out on 93 patients undergoing external drainage of subretinal fluid during scleral buckling surgery for rhegmatogenous retinal detachment. The incidence of successful drainage, incidence of subretinal haemorrhage, incidence of retinal incarceration, and incidence of retinal perforation were determined. RESULTS--The success rate was 97.9% in the ALD group and 84.8% in the SND group (difference-13.1%, 95% CI-26.4% to 2.0%). The incidence of clinically significant subretinal haemorrhage was 4.3% in the ALD group compared with 28.3% in the SND group (difference 24.0%, 95% CI 7.6% to 40.4%). The incidence of incarceration was comparable in each group. There were no cases of retinal perforation. CONCLUSIONS--The use of ALD was associated with a higher rate of successful SRF drainage, and a lower incidence of clinically significant subretinal haemorrhage than SND. ALD is preferred when an endolaser is available. PMID:7547781

An analysis is made of the clinical profile, evolution and differences in morbidity and mortality of low cardiac output syndrome (LCOS) in the postoperative period of cardiac surgery, according to the 3 diagnostic subgroups defined by the SEMICYUC Consensus 2012. A multicenter, prospective cohort study was carried out. ICUs of Spanish hospitals with cardiac surgery. A consecutive sample of 2,070 cardiac surgery patients was included, with the analysis of 137 patients with LCOS. No intervention was carried out. The mean patient age was 68.3±9.3 years (65.2% males), with a EuroSCORE II of 9.99±13. NYHA functional class III-IV (52.9%), left ventricular ejection fraction<35% (33.6%), AMI (31.9%), severe PHT (21.7%), critical preoperative condition (18.8%), prior cardiac surgery (18.1%), PTCA/stent placement (16.7%). According to subgroups, 46 patients fulfilled hemodynamic criteria of LCOS (group A), 50 clinical criteria (group B), and the rest (n=41) presented cardiogenic shock (group C). Significant differences were observed over the evolutive course between the subgroups in terms of time subjected to mechanical ventilation (114.4, 135.4 and 180.3min in groups A, B and C, respectively; P<.001), renal replacement requirements (11.4, 14.6 and 36.6%; P=.007), multiorgan failure (16.7, 13 and 47.5%), and mortality (13.6, 12.5 and 35.9%; P=.01). The mean maximum lactate concentration was higher in cardiogenic shock patients (P=.002). The clinical evolution of these patients leads to high morbidity and mortality. We found differences between the subgroups in terms of the postoperative clinical course and mortality. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

Background Catheter ablation of atrioventricular nodal reentrant tachycardia (AVNRT) is a commonly performed electrophysiology (EP) procedure. Few data exist comparing conventional (CONV) versus novel ablation strategies from both clinical and direct cost perspectives. We sought to investigate the disposable costs and clinical outcomes associated with three different ablation methodologies used in the ablation of AVNRT. Methods We performed a retrospective review of AVNRT ablations performed at Augusta University Medical Center from 2006 to 2014. A total of 183 patients were identified. Three different ablation techniques were compared: CONV manual radiofrequency (RF) (n=60), remote magnetic navigation (RMN)-guided RF (n=67), and cryoablation (CRYO) (n=56). Results Baseline demographics did not differ between the three groups except for a higher prevalence of cardiomyopathy in the RMN group (p<0.01). The clinical end point of interest was recurrent AVNRT following the index ablation procedure. A significantly higher number of recurrent AVNRT cases occurred in the CRYO group as compared to CONV and RMN (p=0.003; OR =7.75) groups. Cost-benefit analysis showed both CONV and RMN to be dominant compared to CRYO. Cost-minimization analysis demonstrated the least expensive ablation method to be CONV (mean disposable catheter cost = CONV US$2340; CRYO US$3515; RMN US$5190). Despite comparable clinical outcomes, the incremental cost of RMN over CONV averaged US$3094 per procedure. Conclusion AVNRT ablation using either CONV or RMN techniques is equally effective and associated with lower AVNRT recurrence rates than CRYO. CONV ablation carries significant disposable cost savings as compared to RMN, despite similar efficacy. PMID:29138585

Patients' esthetic expectations are increasing, and the options of the prosthetic pathways are currently evolving. The objective of this randomized multicenter clinical trial was to assess and compare the esthetic outcome and clinical performance of anterior maxillary all-ceramic implant crowns (ICs) based either on prefabricated zirconia abutments veneered with pressed ceramics or on CAD/CAM zirconia abutments veneered with hand buildup technique. The null hypothesis was that there is no statistically significant difference between the 2 groups. Forty implants were inserted in sites 14 to 24 (FDI) in 40 patients in 2 centers, the Universities of Bern and Geneva, Switzerland. After final impression, 20 patients were randomized into group A, restored with a 1-piece screw-retained single crown made of a prefabricated zirconia abutment with pressed ceramic as the veneering material using the cut-back technique, or group B using an individualized CAD/CAM zirconia abutment (CARES abutment; Institut Straumann AG) with a hand buildup technique. At baseline, 6 mo, and 1 y clinical, esthetic and radiographic parameters were assessed. Group A exhibited 1 dropout patient and 1 failure, resulting in a survival rate of 94.7% after 1 y, in comparison to 100% for group B. No other complications occurred. Clinical parameters presented stable and healthy peri-implant soft tissues. Overall, no or only minimal crestal bone changes were observed with a mean DIB (distance from the implant shoulder to the first bone-to-implant contact) of -0.15 mm (group A) and 0.12 mm (group B) at 1 y. There were no significant differences at baseline, 6 mo, and 1 y for DIB values between the 2 groups. Pink esthetic score (PES) and white esthetic score (WES) values at all 3 examinations indicated stability over time for both groups and pleasing esthetic outcomes. Both implant-supported prosthetic pathways represent a valuable treatment option for the restoration of single ICs in the anterior maxilla ( ClinicalTrials.gov NCT02905838).

To compare mean anterior (AR) and mean overall (OR) tooth size ratios, prevalence of clinically significant tooth size discrepancies (TSDs) and correlation between AR and OR in subjects with Class II division 1 and Class III malocclusion treated by surgical-orthodontic or orthodontic means. Retrospective, cross-sectional. State-funded and private clinics. From pre-treatment cohorts of 770 surgical and 610 non-surgical subjects, Class II division 1 and Class III malocclusion groups were identified with 60 surgical and 60 non-surgical subjects, comprising 30 males and 30 females, in each. AR and OR were calculated by landmarking digital models. Differences in AR and OR and their relationship were analysed using two-way analysis of variance (ANOVA) and a correlation coefficient, respectively. The proportions of the surgical and non-surgical groups with a TSD were assessed using logistic regression. Intra-examiner reproducibility involved re-landmarking 30 randomly selected image sets and differences in ARs and ORs were compared using a paired t-test. Random error was assessed using the intraclass correlation coefficient (ICC). Analyses were performed using SAS (SAS Institute Inc., Cary, NC, USA) at the 5% level of significance. There were no statistically significant differences associated with the measurement of either the mean AR (P = 0·913) or the mean OR (P = 0·874). ICC values were very high (AR = 0·95; OR = 0·90). Differences existed between both Class II and Class III surgical (AR: P<0·001; OR: P<0·001) and non-surgical groups (AR: P = 0·012; OR: P = 0·003). The AR and OR relationship was strong (correlation coefficient = 0·72). The highest percentage of clinically significant TSDs was seen in the AR of both Class II and Class III surgical groups (23·3%). In the cohort examined: AR and OR differed significantly for malocclusion groups. The prevalence of clinically significant TSDs did not differ significantly between surgical and non-surgical groups although the highest percentage of clinically significant TSDs was recorded for AR in Class II and Class III surgical cases. AR and OR were closely related. © 2014 British Orthodontic Society.

[Purpose] Exercise is one of the most important components of a healthy life. The purpose of this study was to analyze exercise beliefs and psychosocial factors in sedentary and active healthy women and observe the changes in these parameters resulting from clinical Pilates exercises and verbal education in healthy women. [Subjects and Methods] Sixty-six healthy women were included in the study. Participants were divided into clinical Pilates (n=21), verbal education (n=25), and control groups (n=20). Prior to and at the end of the study, demographic information, body mass index, waist-hip circumference, exercise beliefs, physical activity index, and psychosocial factors (Rosenberg self-esteem scale, Body Cathexis Index, SF-36 quality of life, Beck Depression Scale, visual analog scale for tiredness) of the subjects were recorded. [Results] Meaningful changes for all the parameters took place in the clinical Pilates and verbal education groups. Our analyses indicated that the changes in the clinical Pilates group were more meaningful than those in the verbal education group. When the data of the study groups were compared with those of the control group, the clinical Pilates group showed meaningful differences. [Conclusion] The result of this study indicate that both clinical Pilates and verbal education are effective in changing exercise beliefs and physical and psychosocial parameters.

We aimed to assess the prognostic relevance of the new Grade Groups in Prostate Cancer (PCa) within a large cohort of European men treated with radical prostatectomy (RP). Data from 27 122 patients treated with RP at seven European centers were analyzed. We investigated the prognostic performance of the new Grade Groups (based on Gleason score 3+3, 3+4, 4+3, 8 and 9-10) on biopsy and RP specimen, adjusted for established clinical and pathological characteristics. Multivariable Cox proportional hazards regression models assessed the association of new Grade Groups with biochemical recurrence (BCR). Prognostic accuracies of the models were assessed using Harrell's C-index. Median follow-up was 29 months (interquartile range, 13-54). The 4-year estimated BCR-free survival (bRFS) for biopsy Grade Groups 1-5 were 91.3, 81.6, 69.8, 60.3 and 44.4%, respectively. The 4-year estimated bRFS for RP Grade Groups 1-5 were 96.1%, 86.7%, 67.0%, 63.1% and 41.0%, respectively. Compared with Grade Group 1, all other Grade Groups based both on biopsy and RP specimen were independently associated with a lower bRFS (all P<0.01). Adjusted pairwise comparisons revealed statistically differences between all Grade Groups, except for group 3 and 4 on RP specimen (P=0.10). The discriminations of the multivariable base prognostic models based on the current three-tier and the new five-tier systems were not clinically different (0.3 and 0.9% increase in discrimination for clinical and pathological model). We validated the independent prognostic value of the new Grade Groups on biopsy and RP specimen from European PCa men. However, it does not improve the accuracies of prognostic models by a clinically significant margin. Nevertheless, this new classification may help physicians and patients estimate disease aggressiveness with a user-friendly, clinically relevant and reproducible method.

Inflammation is a common feature of both peripheral arterial disease (PAD) and periodontal disease. The aim of this study was to evaluate the relationship between PAD and periodontal disease by examining the levels of inflammatory cytokines (pentraxin 3 and interleukin 1β) and high sensitive C-reactive protein from gingival crevicular fluid and serum. A total of 60 patients were included in this cross-sectional study. Patients were divided into two groups based on ankle-brachial index values: with PAD (test group) and non-PAD (control group). Demographic evaluations, clinical periodontal examinations and biochemical analysis for pentraxin 3, interleukin 1β and high sensitive C-reactive protein were performed to compare the two groups. There were no significant differences with respect to gender, age, body mass index, or smoking history (duration, amount) between the two groups (p > 0.05). There were no significant differences between the two groups in terms of clinical periodontal parameters (p > 0.05). Neither gingival crevicular fluid nor serum levels of the cytokines showed differences between the two groups. Logistic regression analysis revealed that, after adjusting for confounding factors (age, gender, diabetes, hypertension and body mass index), periodontitis raised the odds ratio for having PAD to 5.842 (95% confidence interval: 1.558-21.909). Although there were no significant differences with respect to clinical periodontal parameters and biochemical analyses between the study group and control, periodontitis did raise the odds ratio for having PAD. To clarify this possible relationship, future prospective studies are needed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Introduction Carotid artery stenting (CAS) is a promising alternative to surgery in high-risk patients. However, the impact of stent cell design on outcomes in CAS is a matter of continued debate. Aim To compare the periprocedural and clinical outcomes of different stent designs for CAS with distal protection devices. Material and methods All CAS procedures with both closed- and hybrid-cell stents performed at our institution between February 2010 and December 2015 were analyzed retrospectively. Adverse events were defined as death, major stroke, minor stroke, transient ischemic attack and myocardial infarction. Periprocedural and 30-day adverse events and internal carotid artery (ICA) vasospasm rates were compared between the closed-cell and hybrid-cell stent groups. Results The study included 234 patients comprising 146 patients with a closed-cell stent (Xact stent, Abbott Vascular) (mean age: 68.5 ±8.6; 67.1% male) and 88 patients with a hybrid-cell stent (Cristallo Ideale, Medtronic) (mean age: 67.2 ±12.8; 68.2% male). There was no significant difference between the groups with respect to periprocedural or 30-day adverse event rates. While there was no difference in terms of tortuosity index between the groups, there was a higher procedural ICA vasospasm rate in the closed-cell stent group (35 patients, 23%) compared with the hybrid-cell stent group (10 patients, 11%) (p = 0.017). Conclusions The results of this study showed no significant difference in the clinical adverse event rates after CAS between the closed-cell stent group and the hybrid-cell stent group. However, procedural ICA vasospasm was more common in the closed-cell stent group. PMID:28798784

The current study was undertaken to evaluate the clinical efficacy of end-threaded intramedullary pinning for management of various long bone fractures in canines. This study was conducted in two phases, managing 25 client-owned dogs presented with different fractures. The technique of application of end-threaded intramedullary pinning in long bone fractures was initially standardized in 6 clinical patients presented with long bone fractures. In this phase, end-threaded pins of different profiles, i.e., positive and negative, were used as the internal fixation technique. On the basis of results obtained from standardization phase, 19 client-owned dogs clinically presented with different fractures were implanted with end-threaded intramedullary positive profile screw ended self-tapping pin in the clinical application phase. The patients, allocated randomly in two groups, when evaluated postoperatively revealed slight pin migration in Group-I (negative profile), which resulted in disruption of callus site causing delayed union in one case and large callus formation in other two cases whereas no pin migration was observed in Group-II (positive profile). Other observations in Group-I was reduced muscle girth and delayed healing time as compared to Group-II. In clinical application, phase 21 st and 42 nd day post-operative radiographic follow-up revealed no pin migration in any of the cases, and there was no bone shortening or fragment collapse in end-threaded intramedullary positive profile screw ended self-tapping pin. The end-threaded intramedullary positive profile screw ended self-tapping pin used for fixation of long bone fractures in canines can resist pin migration, pin breakage, and all loads acting on the bone, i.e., compression, tension, bending, rotation, and shearing to an extent with no post-operative complications.

Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with significant pathological and clinical similarities. Numerous studies have indicated a relationship between rheumatoid arthritis and periodontal disease. The aim of this study was to compare the TNF-α levels in saliva among patients with Rheumatoid arthritis (RA) and chronic periodontitis as well as healthy subjects. One hundred and seventy-one patients were enrolled in this cross-sectional study. Fifty-seven patients diagnosed of RA, 57 patients with chronic periodontitis and 57 healthy subjects. These patients have been examined with regard to TNF-α level from salivary samples. Their teeth were examined with regard to Plaque Index , Gingival Index, probing depth and clinical attachment level.All patients were non-smokers. The results revealed a significant difference in all periodontal parameters among the three groups. The chronic periodontitis group showed a significantly higher value in all clinical periodontal parameters in comparison to both the RA and healthy groups. No significant difference was found between salivary TNF-α level among the three study groups. Patients with chronic periodontitis had the highest periodontal indices. However there was no significant difference regarding the level of salivary TNF-α. Hence, suppression of proinflammatory cytokines might prove beneficial in suppressing periodontal diseases among RA patients.

This study aimed to investigate emotion expression in a large group of children, adolescents and adults with Anorexia Nervosa (AN), and investigate the associated clinical correlates. One hundred and forty-one participants (AN=66, HC= 75) were recruited and positive and negative film clips were used to elicit emotion expressions. The Facial Activation Coding system (FACES) was used to code emotion expression. Subjective ratings of emotion were collected. Individuals with AN displayed less positive emotions during the positive film clip compared to healthy controls (HC). There was no significant difference between the groups on the Positive and Negative Affect Scale (PANAS). The AN group displayed emotional incongruence (reporting a different emotion to what would be expected given the stimuli, with limited facial affect to signal the emotion experienced), whereby they reported feeling significantly higher rates of negative emotion during the positive clip. There were no differences in emotion expression between the groups during the negative film clip. Despite this individuals with AN reported feeling significantly higher levels of negative emotions during the negative clip. Diminished positive emotion expression was associated with more severe clinical symptoms, which could suggest that these individuals represent a group with serious social difficulties, which may require specific attention in treatment.

The aim of the present study was to investigate retrospectively the plasma concentration of alpha-tocopherol in dogs with naturally acquired chronic kidney disease (CKD), at different stages of severity. Forty dogs (CKD group) with different stages of CKD (IRIS 1 n=12, IRIS 2 n=8, IRIS 3 n=11, IRIS 4 n=9) and 20 clinically healthy dogs were considered. Plasma alpha-tocopherol was assessed in both groups through high performance liquid chromatography (HPLC). Dogs of CKD group showed significantly lower (p=0.0002) levels of plasma alpha-tocopherol compared with clinically healthy dogs. A significant difference (p<0.04) in the number of patients with plasma alpha-tocopherol > or ≤ 21.5 ppm was found in CKD patients at different stages of severity. No significant correlation between plasma levels of alpha-tocopherol and plasma creatinine was found. In the present study, dogs affected by spontaneous CKD showed significantly lower plasma concentrations of alpha-tocopherol compared with clinically healthy dogs. Plasma alpha-tocopherol deficiency seems to be more severe in IRIS stage 1 and 4, compared with IRIS stage 2 and 3. The finding of marked alpha-tocopherol deficiency in patients in IRIS stage 1 should encourage further studies on the early use of prescription renal diet and antioxidant in this group of patients.

The purpose of this systematic review was to address the treatment of rotator cuff tears by applying tissue engineering approaches to improve tendon healing, specifically platelet rich plasma (PRP) augmentation, stem cells, and scaffolds. Our systematic search was performed using the combination of the following terms: “rotator cuff”, “shoulder”, “PRP”, “platelet rich plasma”, “stemcells”, “scaffold”, “growth factors”, and “tissue engineering”. No level I or II studies were found on the use of scaffolds and stem cells for rotator cuff repair. Three studies compared rotator cuff repair with or without PRP augmentation. All authors performed arthroscopic rotator cuff repair with different techniques of suture anchor fixation and different PRP augmentation. The three studies found no difference in clinical rating scales and functional outcomes between PRP and control groups. Only one study showed clinical statistically significant difference between the two groups at the 3-month follow up. Any statistically significant difference in the rates of tendon rerupture between the control group and the PRP group was found using the magnetic resonance imaging. The current literature on tissue engineering application for rotator cuff repair is scanty. Comparative studies included in this review suggest that PRP augmented repair of a rotator cuff does not yield improved functional and clinical outcome compared with non-augmented repair at a medium and long-term followup.

Nonspecific neck pain patients form a heterogeneous group with different musculoskeletal impairments. Classifying nonspecific neck pain patients into subgroups based on clinical characteristics might lead to more comprehensive diagnoses and can guide effective management. To establish consensus among a group of experts regarding the clinical criteria suggestive of a clinical dominance of 'articular', 'myofascial', 'neural', 'central' and 'sensorimotor control' dysfunction patterns distinguishable in patients with nonspecific neck pain. Delphi study. A focus group with 10 academic experts was organized to elaborate on the different dysfunction patterns discernible in neck pain patients. Consecutively, a 3-round online Delphi-survey was designed to obtain consensual symptoms and physical examination findings for the 5 distinct dysfunction patterns resulting from the focus group. A total of 21 musculoskeletal physical therapists from Belgium and the Netherlands experienced in assessing and treating neck pain patients completed the 3-round Delphi-survey. Respectively, 33 (response rate, 100.0%), 27 (81.8%) and 21 (63.6%) respondents replied to rounds 1, 2 and 3. Eighteen 'articular', 16 'myofascial', 20 'neural', 18 'central' and 10 'sensorimotor control' clinical indicators reached a predefined ≥80% consensus level. These indicators suggestive of a clinical dominance of 'articular', 'myofascial', 'neural', 'central', and 'sensorimotor control' dysfunction patterns may help clinicians to assess and diagnose patients with nonspecific neck pain. Future validity testing is needed to determine how these criteria may help to improve the outcome of physical therapy interventions in nonspecific neck pain patients. Copyright © 2016 Elsevier Ltd.

A Clinical Evaluation of Deproteinization and Different Cavity Designs on Resin Restoration Performance in MIH-Affected Molars: Two-Year Results.

PubMed

Sönmez, Hayriye; Saat, Sinem

The aim of this study was to evaluate the clinical effects of deproteinization of the hypomineralized enamel and different cavity designs on the performance of the composite resin restorations(CRRs) placed into the cavities of MIH (molar incisor hypomineralization)-affected molars. 95 MIH-affected permanent first molars (PFMs) and 31 caries but not MIH-affected PFMs (126 teeth in total) were included in the study. The MIH-affected molars were divided into three groups. In Group I, all hypomineralized tissue was removed until healthy enamel was reached. In Group II, carious and cheesy hypomineralized tissue was removed until a reasonable resistance was detected in the hypomineralized tissue. In Group III, cavities designed as Group II, differently from this group deproteinization of the left hypomineralized tissue was performed prior to the placement of CRRs. Group IV served as the control group consisting of unaffected carious PFMs. Restorations were evaluated according to modified USPHS criteria for 24 months. The retention rates were 93.7% for Group I, 80.7% for Group II, 93.5% for Group III and 100% for Group IV. The success rate for the restorations in Group II proved significantly lower (p<0.05) than that of the other three groups. No significant difference in success rates was observed between Group I, Group III and Group IV (p>0.05) at the end of 24 months. Failure of the restorations was predominant in the group that the hypomineralized tissue was left surrounding the cavities. Deproteinization of the hypomineralized enamel was found to enhance the retention rates of CRRs.

Clinical documentation can be an underappreciated. Trauma Centers (TCs) are now routinely evaluated for quality performance. TCs with poor documentation may not accurately reflect actual injury burden or comorbidities and can impact accuracy of mortality measures. Markers exist to adjust crude death rates for injury severity: observed over expected deaths (O/E) adjust for injury; Case Mix Index (CMI) reflects disease burden, and Severity of Illness (SOI) measures organ dysfunction. We aim to evaluate the impact of implementing a Clinical Documentation Improvement Program (CDIP) on reported outcomes. Review of 2-years of prospectively collected data for trauma patients, during the implementation of CDIP. A two-group prospective observational study design was used to evaluate the pre-implementation and the post-implementation phase of improved clinical documentation. T-test and Chi-Squared were used with significance defined as p < 0.05. In the pre-implementation period, there were 49 deaths out of 1419 (3.45%), while post-implementation period, had 38 deaths out of 1454 (2.61%), (non-significant). There was however, a significant difference between O/E ratios. In the pre-phase, the O/E was 1.36 and 0.70 in the post-phase (p < 0.001). The two groups also differed on CMI with a pre-group mean of 2.48 and a post-group of 2.87 (p < 0.001), indicating higher injury burden in the post-group. SOI started at 2.12 and significantly increased to 2.91, signifying more organ system dysfunction (p < 0.018). Improved clinical documentation results in improved accuracy of measures of mortality, injury severity, and comorbidities and a more accurate reflection in O/E mortality ratios, CMI, and SOI.

To investigate the clinical efficacy of three toothpastes in controlling established gingivitis and plaque over 6 months. 135 subjects were enrolled in a single-center, double-blind, parallel group, randomized clinical study. Subjects were randomly assigned to one of three treatments: triclosan/copolymer/fluoride dentifrice containing 0.3% triclosan, 2.0% copolymer and 1,450 ppm F as sodium fluoride in a silica base; herbal/bicarbonate dentifrice containing herbal extract and 1,400 ppm F as sodium fluoride in a sodium bicarbonate base; or fluoride dentifrice containing 450 ppm F as sodium fluoride, and 1,000 ppm F as sodium monofluorophosphate. Subjects were instructed to brush their teeth twice daily for 1 minute for 6 months. After 6 months, subjects assigned to the triclosan/copolymer/fluoride group exhibited statistically significant reductions in gingival index scores and plaque index scores as compared to subjects assigned to the herbal/bicarbonate group by 35.4% and 48.9%, respectively. There were no statistically significant differences in gingival index and plaque index between subjects in the herbal/ bicarbonate group and those in the fluoride group. The triclosan/copolymer/fluoride dentifrice was statistically significantly more effective in reducing gingivitis and dental plaque than the herbal/bicarbonate dentifrice, and this difference in efficacy was clinically meaningful.

Are some health professionals more cognizant of clinical governance development concepts than others? Findings from a New Zealand study.

PubMed

Gauld, Robin; Horsburgh, Simon

2016-06-01

Clinical governance has been promoted in recent years as core to improving patient safety. Effective clinical governance requires partnerships between 'management' and health professionals as well as equal involvement of all professional groups. Professionals must also be willing to engage in clinical governance activities such as working to improve care systems and patient safety. There is limited research into the relative understanding of core clinical governance concepts amongst different professional groups or the extent to which professionals are prepared to take up opportunities to 'change the system'. A 2012 national survey study of health professionals employed in New Zealand health boards sought to probe understanding of and commitment to clinical governance following introduction of a 2009 policy. Respondent data showed only limited policy implementation had occurred. Regression analyses revealed statistically significant differences in perceptions of knowledge of clinical governance concepts and structures by gender, age, experience and profession, as well as in seeking opportunities to change the system. These findings have implications for policy makers in terms of ensuring that clinical governance implementation provides equal opportunity for engendering involvement of different health professionals. © The Author 2015.

2017-06-06

Guided internet-based intervention beyond hearing aid (HA) fitting has been shown to be efficacious in randomised controlled trials (RCTs). However, internet interventions have rarely been applied clinically as a part of regular aural rehabilitation (AR). Our aim was to evaluate the effectiveness of internet-based AR for HA users from a clinical population. The Hearing Handicap Inventory for the Elderly (HHIE) was used as the primary outcome measure, and the Communication Strategies Scale (CSS) and the Hospital Anxiety and Depression Scale were used as secondary outcome measures. All questionnaires were administered before and directly after the intervention and at 6 months postintervention. We used a parallel group design (RCT). The data were collected in 2013-2014 at three different clinics. Seventy-four HA users were randomly assigned to receive either full internet-based AR (intervention group, n=37) or one element of the internet-based AR (control group, n=37). Data were analysed following the intention-to-treat principle. Each group showed improved HHIE scores over time and did not differ significantly from each other. The intervention group showed significantly greater improvement compared with the control group for the CSS total and the non-verbal subscale scores. The intervention group and control group were also subdivided into two age groups: 20-59 years and 60-80 years. Significantly better improvement on the CSS total and non-verbal subscale scores was found in the older group compared with the younger participants. This study indicates that participants in an internet-based intervention applied in general clinical practice showed improved self-reported communication skills compared with a control group. Receiving a full intervention was not more effective in improving self-reported hearing problems than receiving just one element of the internet-based intervention.

1998-05-01

A clinical trial, including five East Coast fever (ECF) control strategies (involving tick control and/or immunisation by infection-and-treatment) in five different groups of traditionally managed Sanga cattle, was conducted in Central Province of Zambia over 2.5 years between 1992 and 1995. Two groups were kept under intensive tick control by weekly acaricide treatment by hand spray; (one immunised and one non-immunised), two groups were under no tick control (one immunised and one non-immunised), and a fifth, immunised group was maintained under strategic tick control (18 sprays yr-1). ECF-specific mortality was highest in the non-immunised and non-treated group, while no difference in ECF-specific mortality could be observed between animals treated for ECF by immunisation or by tick control. Acaricide treatment and/or immunisation reduced the risk of clinical ECF by 92%. The results of an artificial challenge experiment at the end of the field trial indicated that about 60% of the animals in the control group had become infected with Theileria parva without showing clinical signs. ECF incidence in non-vaccinated cattle markedly declined six months after immunisation--suggesting that the carrier state induced by immunisation did not lead to a persistent high incidence, and might accelerate the progress to endemicity.

This study aimed to evaluate the effect of methylprednisolone on prevention of ovarian hyperstimulation syndrome (OHSS) in polycystic ovarian syndrome (PCOS) patients undergoing in-vitro fertilisation (IVF). This randomised controlled trial was carried out between November 2009 and December 2013. A total of 219 eligible patients were randomly allocated for treatment (n = 108) or control groups (n = 111). The treatment group received oral methylprednisolone starting from the first day of stimulation. These patients also received an intravenous dose of methylprednisolone on the days of egg collection and embryo transfer. The control group received no glucocorticoid treatment to prevent OHSS. Nineteen percent of patients (18/93) who received methylprednisolone developed OHSS compared with 16.5% (15/91) in the control group and no significant difference was found (p = .61). There were no significant differences between treatment and control groups in the rates of implantation (10% versus 11%, p = .77) and clinical pregnancy (23.2% versus 17.7%, p = .46). Methylprednisolone did not reduce the incidence and severity of OHSS in PCOS patients undergoing IVF and no improvement in clinical outcomes was observed. Impact statement No significant differences were found in OHSS incidence and clinical outcomes between women who received methylprednisolone and control group. There seems to be no benefit for the routine use of glucocorticoids in IVF/ICSI treatments.

Patient-centred outcomes are being given great attention by the dental scientific community. The Oral Health Impact Profile -14 questionnaire (OHIP-14) has been introduced to address patients' success criteria when describing the impact of oral rehabilitations on quality of life (OHrQoL). Thirty-five patients wearing a full-arch implant-prosthesis being in place between 4 and 6 years before this analysis were considered eligible and then enrolled in the present retrospective study. According to their prosthetic anamnesis, two groups were defined: delayed loading group (IL-group) and immediate loading group (IL-group). At the moment of analysis, clinical and radiographic parameters were collected, and patients were asked to complete the Oral Health Impact Profile -14 questionnaire (OHIP-14) in order to measure their OHrQoL. Independent t-test showed total OHIP-14 scores to be not significantly different between groups; however, the domains "Functional limitation" and "physical disability" resulted significantly higher in patients within the DL-group. On the contrary, social disability was higher in the IL-group. When the comparison was performed taking sex into account, no significant differences between groups were highlighted. Instead, the stratification for years of follow-up led to significant evidences. When the follow-up was shorter (less-than-5 years), the functional limitation reported scores were higher. Within the limitations of this study, the analysis supports the absence of significant differences between immediate loading and delayed loading full-arch protocol in term of clinical, radiological parameters and OHrQoL.

Objective The aim of this study was to provide a systematic safety analysis of gadobutrol after more than 29 million applications in clinical routine. Materials and Methods Forty-two clinical development phase II to IV studies on gadobutrol or comparator and the postmarketing safety surveillance database for gadobutrol (1998–2015) were analyzed. Adverse events (AEs) and drug-related AEs were evaluated in the clinical development database and spontaneous adverse drug reactions (ADRs) in the postmarketing database. Subgroup analyses were run on patients with special medical history and on patients of different age groups. Results In the clinical development studies, 6809 and 2184 patients received gadobutrol or comparators, respectively. The incidence of drug-related AEs was 3.5% for both groups. With the exception of nausea (0.7% related cases in both groups), all other drug-related AEs were 0.3% or less in both groups. Hypersensitivity reactions were sporadic (<0.1%). Patients with history of allergies to contrast agents experienced slightly more drug-related AEs. No differences were seen between age groups. The overall reporting rate of ADRs from postmarketing surveillance was 0.05%. The most frequent ADRs were anaphylactoid/hypersensitivity reactions, nausea, vomiting, and dyspnea. For 3 single-agent reports of nephrogenic systemic fibrosis, using a conservative approach, association with gadobutrol could not be excluded. Conclusions Gadobutrol is well tolerated and has a favorable safety profile for patients of all age groups. PMID:26964075

2012-02-01

To compare the attitudes toward and perceptions of institutional practices that can influence patient safety between all professional groups at a university medical center. A questionnaire measuring nine dimensions of organizational and safety culture was distributed to all hospital workers. Each item was rated on a 1 ('strongly disagree') to 5 ('strongly agree') scale. Professionals (2995), grouped as 'physicians' (16.6%), 'nurses' (40.3%), 'clinical workers' (e.g. psychologists; 21.7%), 'laboratory workers' (e.g. technicians; 11%) and 'non-medical workers' (e.g. managers; 10.4%). One-way analysis of variances (ANOVAs) carried out separately on each dimension with professional group as the independent variable of interest. Differences in ratings of organizational and safety culture were found across professional groups. Physicians and non-medical workers tended to rate the dimensions of organizational and safety culture more positively than did nurses, clinical workers and laboratory workers. For example, physicians gave more positive ratings of 'institutional commitment to safety' than did nurses, clinical workers and laboratory workers (mean = 3.71 vs. 3.62, 3.61 and 3.58, respectively, P < 0.01) and non-medical workers gave more positive ratings than did physicians, nurses, clinical workers and laboratory workers to 'perceptions towards the hospital' (mean = 3.69 vs. 3.39, 3.36, 3.49 and 3.47, respectively, P < 0.001). Interventions to promote safety culture should be tailored to the target group as attitudes and perceptions may differ among groups.

Obesity is a well-known cardiovascular disease risk factor. We evaluated the relationship between the waist-hip ratio (WHR), as a surrogate marker of central obesity, and clinical outcomes in patients with non-ST-segment elevation myocardial infarctions (NSTEMIs) undergoing percutaneous coronary interventions (PCIs). Between 2008 and 2010, NSTEMI patients who underwent PCI and who had available anthropometric data were divided into three groups according to their WHR tertile range. Clinical outcomes in the groups were analyzed. Increasing incidences of hypertension and diabetes mellitus were associated with increasing WHR. As the WHR increased, a disintegration of patient metabolic patterns was documented in laboratory findings. There was no difference in the 1-year mortality rates between the three groups. However, increasing 1-year major adverse cardiovascular event rates were documented as the WHR increased (13, 14.7, and 19.4% in tertile groups 1-3, respectively; P=0.005). After adjusting for confounding variables, the highest tertile group was associated with increased 1-year mortality and major adverse cardiovascular event rates compared with the lowest tertile group. These differences arose from the female subgroup, suggesting that the magnitude of the central obesity effect might be greater in female than in male patients. Central obesity, represented by WHR, was associated with poor clinical outcomes in NSTEMI patients undergoing PCI, particularly among women.

In China, the five-year program of undergraduate education for stomatology consists of four years of lecture courses and one year of internship focused on clinical training. Dental schools provide this clinical training either in their own clinics (referred to as the one-stage pattern because all forms of practice are completed together) or by placing students in external clinics usually at non-affiliated hospitals (referred to as the three-stage program because the three primary areas are taught separately). The aims of this study were to investigate differences in teaching effect between the one-stage and the three-stage patterns and to evaluate advantages and disadvantages of the two patterns. A three-section, 31-item questionnaire was designed to assess basic and clinic information about the interns' training and their self-confidence in performing clinical procedures. The survey was administered to graduates who finished the fifth-year internship in 2012-14. Of the 356 individuals invited to participate, 303 graduates who spent their intern years in 43 academic dental institutions returned completed surveys (response rate of 85%). The one-stage group (n=121) reported longer independent operation time than the three-stage group (n=182) (p<0.01). No significant difference was found between the groups for assessment of clinic infrastructure (p=0.121). The interns were most confident in oral hygiene instruction and scale and polish (overall median=5), but showed low confidence in rubber dam placement and four other procedures (overall median=2). The one-stage group rated their confidence level higher than the three-stage group on comprehensive skills such as arranging appointments and managing patients and procedures needing long treatment periods such as molar endodontics. The three-stage group showed higher confidence on more specialized procedures such as surgical extractions and suturing. This study found that both of the two intern patterns had advantages and shortcomings in clinical training in various procedures. Combining the two could be a way to improve clinical education in China.

Clinical practice of Palliative Sedation (PS) varies between institutions worldwide and sometimes includes problematic practices. Little available research points at different definitions and frameworks which may contribute to uncertainty of healthcare professionals in the application of PS. This analysis investigates what demographic factors and characteristics of treatment practices differ between institutions with high versus low sedation rates estimates in Palliative and Hospice Care in Germany. Data sets from 221 organisations from a prior online survey were separated into two sub-groups divided by their estimated sedation rate A) lower/equal to 16% (n = 187; 90.8%) and B) higher than 16% (n = 19; 9.2%) for secondary analysis. Demographic factors and characteristics of PS treatment practices between the two groups were compared using T-Tests and Chi 2 / Fisher Exact Tests and considered significant (*) at two-sided p < .05. Organisations in group B report that they discuss PS for a higher proportion of patients (38.5%/10.2%, p < 0.000**), rate agitation more often as an indications for PS (78.9%/ 53.5%, p = 0.050*), and are more likely to use Lorazepam (63.2%/ 37.4%, p = 0.047*), Promethazin (26.3%/ 9.6%, p = 0.044*), and (Es-)Ketamin (31.6%/ 12.8%, p = 0.039*) than representatives in group A. Both groups differ significantly in their allocation of three case scenarios to different types of PS. Both definitions and patterns of clinical practice between palliative and hospice care representatives show divergence, which may be influenced one by another. A comprehensive framework considering conceptual, clinical, ethical, and legal aspects of different definitions of PS could help to better distinguish between different types and nuances of PS.

A post-marketing clinical study was previously conducted in pediatric patients with respiratory infection to evaluate the pharmacokinetics, efficacy and safety of cefcapene pivoxil (CFPN-PI) fine granules for children. Based on the results from this study, we evaluated PK/PD breakpoints and clinical/bacteriological effects of CFPN-PI at free drug concentrations in pediatric patients with respiratory infection to determine an effective and safe dosage regimen of CFPN-PI. The following results were obtained from 61 pediatric patients evaluated in our research. 1) The response rate of pediatric respiratory infection to CFPN-PI was 100% for laryngopharyngitis, 84.6% for acute bronchitis, 100% for tonsillitis, 100% for pneumonia and 95.8% for all. 2) The bacteriological response (eradication rate of Haemophilus influenzae, Streptococcus pyogenes, Moraxella catarrhalis, Streptococcus pneumoniae, etc.) of pediatric respiratory infection to CFPN-PI was 87.5% for laryngopharyngitis, 66.7% for acute bronchitis, 75.0% for tonsillitis, 63.6% for pneumonia and 73.8% for all. 3) The blood concentration simulation demonstrated that the PK/PD breakpoint exceeding the time above MIC (TAM) of 40% after administration of CFPN-PI 3 mg/kg three times daily was 0.27 microg/mL. 4) The pediatric patients with respiratory infection were stratified by the TAM (%) of CFPN-PI into 40% to 100% (TAM > or = 40% group) and 0% to 40% (TAM < 40% group) to compare the clinical and bacteriological effects of CFPN-PI. The clinical and bacteriological response rates, respectively, were 97.4% and 77.8% in the TAM > or = 40% group, and 88.9% and 62.5% in the TAM < 40% group. There was no difference in the clinical effect between the two TAM-stratified groups. On the other hand, the bacteriological effect, i.e., eradication rate, tended to be higher in the TAM > or = 40% group than in the TAM < 40% group, although the between-group difference was not statistically significant.

Few studies have investigated the effect of veterinary clinical procedures on the welfare of dogs, with specific emphasis on the veterinary practice environment. Clinicopathologic variables have also not been assessed in these potentially stressful situations. Similar to human clinical studies, the veterinary clinical waiting room could present a significant stress factor for dogs. The present study was designed to investigate the effect of waiting-room environment on serum cortisol and glucose alterations as well as heart rate in privately owned healthy dogs. The clinical trial included 24 healthy dogs that were divided into 2 groups: the clinical waiting-room group (A) and the control group (B) that waited outside in a garden. During the entire experiment, 18 dogs (9 dogs per group) were monitored with a human heart rate monitor fastened around the chest. After 20 minutes of waiting, blood samples were collected from all of the dogs (24 dogs) to determine serum cortisol concentration. Serum cortisol concentration and mean, maximum, and minimum heart rate were significantly higher in group A compared with group B, but there was no statistical difference in serum glucose concentrations between the 2 study groups. Results of this study suggest that the waiting room is a potentially stressful situation for dogs in clinical veterinary practice, when compared with a garden, based on the assessment of adrenal cortex function and heart rate evaluation. © 2014 American Society for Veterinary Clinical Pathology and European Society for Veterinary Clinical Pathology.

To establish if preoperative maropitant significantly reduced intraoperative isoflurane requirements and reduced clinical signs associated with postoperative nausea and vomiting (PONV) in dogs. Randomized clinical trial. Twenty-four healthy, client-owned dogs undergoing routine ovariohysterectomy. Premedication involved acepromazine (0.03 mg kg -1 ) combined with methadone (0.3 mg kg -1 ) intramuscularly 45 minutes before anaesthetic induction with intravenous (IV) propofol, dosed to effect. Meloxicam (0.2 mg kg -1 ) was administered intravenously. Dogs were randomly assigned to administration of saline (group S; 0.1 mL kg -1 , n=12) or maropitant (group M; 1 mg kg -1 , n=12) subcutaneously at time of premedication. Methadone (0.1 mg kg -1 IV) was repeated 4 hours later. Anaesthesia was maintained with isoflurane in oxygen, dosed to effect by an observer unaware of group allocation. The dogs were assessed hourly, starting 1 hour postoperatively, using the short form of the Glasgow Composite Pain Score (GCPS), and for ptyalism and signs attributable to PONV [score from 0 (none) to 3 (severe)] by blinded observers. Owners completed a questionnaire at the postoperative recheck. Overall mean±standard deviation end-tidal isoflurane percentage was lower in group M (1.19±0.26%) than group S (1.44±0.23%) (p=0.022), but was not significantly different between groups at specific noxious events (skin incision, ovarian pedicle clamp application, cervical clamp application, wound closure). Cardiorespiratory variables and postoperative GCPS were not significantly different between groups. Overall, 50% of dogs displayed signs attributable to PONV, with no difference in PONV scores between groups (p=0.198). No difference in anaesthetic recovery was noted by owners between groups. Maropitant reduced overall intraoperative isoflurane requirements but did not affect the incidence of PONV. Maropitant provided no significant benefits to dogs undergoing ovariohysterectomy with this anaesthetic and analgesic protocol, although clinically significant reductions in isoflurane requirements were noted.

Raz, Raul

2003-10-01

The clinical significance and management of asymptomatic bacteriuria (ASB) differs according to different groups of patients. ASB requires antibiotic treatment in pregnant women, children aged 5-6 years and prior to invasive genitourinary procedures. However, there is a consensus that ASB in the elderly, healthy school girls and young women, diabetic women and patients with indwelling catheters or intermittent catheterization has no clinical significance and antibiotic prescription is not indicated.

Clinical Characteristics and Outcomes Are Similar in ARDS Diagnosed by Oxygen Saturation/Fio2 Ratio Compared With Pao2/Fio2 Ratio

PubMed Central

2015-01-01

BACKGROUND: Oxygen saturation as measured by pulse oximetry/Fio2 (SF) ratio is highly correlated with the Pao2/Fio2 (PF) ratio in patients with ARDS. However, it remains uncertain whether SF ratio can be substituted for PF ratio for diagnosis of ARDS and whether SF ratio might identify patients who are systemically different from patients diagnosed by PF ratio. METHODS: We conducted a secondary analysis of a large observational prospective cohort study. Patients were eligible if they were admitted to the medical ICU and fulfilled the Berlin definition of ARDS with hypoxemia criteria using either the standard PF threshold (PF ratio ≤ 300) or a previously published SF threshold (SF ratio ≤ 315). RESULTS: Of 362 patients with ARDS, 238 (66%) received a diagnosis by PF ratio and 124 (34%) by SF ratio. In a small group of patients who received diagnoses of ARDS by SF ratio who had arterial blood gas measurements on the same day (n = 10), the PF ratio did not meet ARDS criteria. There were no major differences in clinical characteristics or comorbidities between groups with the exception of APACHE (Acute Physiology and Chronic Health Evaluation) II scores, which were higher in the group diagnosed by PF ratio. However, this difference was no longer apparent when arterial blood gas-dependent variables (pH, Pao2) were removed from the APACHE II score. There were also no differences in clinical outcomes including duration of mechanical ventilation (mean, 7 days in both groups; P = .25), duration of ICU stay (mean, 10 days vs 9 days in PF ratio vs SF ratio; P = .26), or hospital mortality (36% in both groups, P = .9). CONCLUSIONS: Patients with ARDS diagnosed by SF ratio have very similar clinical characteristics and outcomes compared with patients diagnosed by PF ratio. These findings suggest that SF ratio could be considered as a diagnostic tool for early enrollment into clinical trials. PMID:26271028

Marketing communication and brand identity is a fundamental principle of advertising and end-user engagement. Health researchers have begun to apply this principle to trial recruitment in primary care. The aim of this study was to evaluate whether a Teaser Campaign using a series of postcards in advance of a conventional mail-out increases the number of primary care clinics that engage with a clinical trial. Embedded randomised recruitment trial across primary care clinics (general practitioners and physiotherapists) in the Sydney metropolitan area. Clinics in the Teaser Campaign group received a series of branded promotional postcards in advance of a standard letter inviting them to participate in a clinical trial. Clinics in the Standard Mail group did not receive the postcards. From a total of 744 clinics that were sent an invitation letter, 46 clinics in the Teaser Campaign group and 40 clinics in the Standard Mail group responded (11.6% total response rate). There was no between-group difference in the odds of responding to the invitation letter (odds ratio = 1.18, 95% confidence interval = 0.75-1.85, p = 0.49). For physiotherapy clinics and general practice clinics, the odds ratios were 1.43 (confidence interval = 0.82-2.48, p = 0.21) and 0.77 (confidence interval = 0.34-1.75, p  = 0.54), respectively. A Teaser Campaign using a series of branded promotional postcards did not improve clinic engagement for a randomised controlled trial in primary care.

A Community Psychiatry program was begun, based on the needs and requests of a clinic (this approach is restricted because there are institutional factors that only the institution can change). The work was aimed at sensitizing the beneficiaries and change clinic factors modifiable through operative group technique. When a great deal of every day stereotypes appeared, role playing was used: as a result, people in the clinic realized how they acted and how they asked from others behaviors that they themselves found difficult to show. As results, it was found that when workers were confronted with reality, desertion from operative groups appeared, with projection of problems (them, not me), great fear of change (fantasized in different ways), group passivity and the image of the institution, that the group saw as a persecutor.

Background Changes in the angiotensin-converting enzyme (ACE) gene may contribute to the increase in blood pressure and consequently to the onset of heart failure (HF). The role of polymorphism is very controversial, and its identification in patients with HF secondary to Chagas disease in the Brazilian population is required. Objective To determine ACE polymorphism in patients with HF secondary to Chagas disease and patients with Chagas disease without systolic dysfunction, and to evaluate the relationship of the ACE polymorphism with different clinical variables. Methods This was a comparative clinical study with 193 participants, 103 of them with HF secondary to Chagas disease and 90 with Chagas disease without systolic dysfunction. All patients attended the outpatient department of the General Hospital of the Federal University of Goias general hospital. Alleles I and D of ACE polymorphism were identified by polymerase chain reaction of the respective intron 16 fragments in the ACE gene and visualized by electrophoresis. Results In the group of HF patients, 63% were male, whereas 53.6% of patients with Chagas disease without systolic dysfunction were female (p = 0,001). The time from diagnosis varied from 1 to 50 years. Distribution of DD, ID and II genotypes was similar between the two groups, without statistical significance (p = 0,692). There was no difference in clinical characteristics or I/D genotypes between the groups. Age was significantly different between the groups (p = 0,001), and mean age of patients with HF was 62.5 years. Conclusion No differences were observed in the distribution of (Insertion/Deletion) genotype frequencies of ACE polymorphism between the studied groups. The use of this genetic biomarker was not useful in detecting a possible relationship between ACE polymorphism and clinical manifestations in HF secondary to Chagas disease. PMID:28977050

Comparison of long-term clinical results of two different pharmaceutical formulations used in corneal cross-linking (CXL) in keratoconus patients. Sixty eyes of 60 keratoconus patients underwent CXL in two groups. We used riboflavin preparations from Sina Darou, Iran in group A, and Streuli Pharma, Switzerland in group B. Here we made inter-group comparison of changes in vision, refraction, Pentacam indices, corneal biomechanical indices, and endothelial cell count (ECC) 18 months after CXL. Since four patients were lost to follow-up, 56 eyes (28 eyes in each group) were compared. Mean improvement in uncorrected visual acuity (UCVA) was 0.31 ± 0.65 LogMAR (P=0.014) in group A and 0.24 ± 0.62 LogMAR (P=0.082) in group B. Best corrected visual acuity (BCVA) remained quite unchanged in both groups (P=0.774). Mean spherical refractive error reduced by 0.45 ± 1.15 diopter (D) (P=0.041) in group A and 0.27 ± 1.73 D (P=0.458) in group B (P=0.655). Cylinder error and spherical equivalent had a similar trend without any change. Max-K (P=0.006) and mean-K (P=0.044) decreased significantly more in group A compared to group B. The reduction in CCT was significantly more in group A than group B (P=0.004). Q-value was quite unchanged in both groups (P=0.704). The inter-group difference in CH reduction was borderline significant statistically (P=0.057). Changes in corneal resistance factor and endothelial cell count were not significantly different between two groups (P=0.117 and P=0.229). Clinical results of CXL with the domestic preparation of riboflavin are similar to that achieved with the Swiss made product in some aspects, and it is the preferred brand in some other aspects. This study will continue to report longer follow-up results. IRCT201212034333N2.

The prevalence of overweight and obesity is on the increase the world over, which imposes an ever-increasing burden on societies and health care systems. This study sought to investigate the effect of motivational interviewing (MI) on a weight-loss program based on the protection motivation theory (PMT). This randomized clinical trial study, comprising pretest-posttest with a control group, was conducted on 150 overweight and obese women attending a private nutrition clinic for the first time. Samples were randomly selected using the clinic's records and then allocated to three groups (50 women in each group) receiving: 1) a standard weight-control program; 2) motivational interviewing; and 3) MI plus intention intervention. Data were collected using a researcher-made questionnaire through in-person interviews and were analyzed using SPSS (version 11) and statistical tests, including the Kruskal-Wallis test, one-way analysis of variance, paired t-test, and linear regression model. In the two intervention groups, the PMT construct scores, namely susceptibility (P = 0.001), severity (P = 0.001), rewards (P =0.004), self-efficacy (P = 0.001), response efficacy (P = 0.001), and costs (P = 0.014), were significantly increased compared to those in the control group. The anthropometric status was statistically significant in the MI group (P = 0.001) and the MI plus intention-intervention group (P = 0.001) at 2 months' follow-up, while in the control group, weight was meaningfully different after the intervention (P = 0.027). Weight was different between the groups after the intervention, with the Tukey test demonstrating that the differences were statistically significant between the control group and the MI group. Our results demonstrated that MI, combined with the implementation of intention intervention, increased weight loss and PMT construct scores in our study population.

To evaluate the combined effect of endometrial thickness and pattern on clinical outcome in patients undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). Cycles of IVF/ICSI-ET conducted between January 2003 and December 2008 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic characteristics were recorded on the day of hCG administration. In the combined analysis, endometrial thickness groups (group 1: equal or <7 mm; group 2: 7-14 mm; group 3: >14 mm) were subdivided into two endometrial patterns (pattern A: triple-line; pattern B: no-triple line). Clinical pregnancy rate (CPR) and early miscarriage rate in different groups were analyzed. A total of 2896 cycles were reviewed. Clinical pregnancy rate (CPR) was 24.4% in group 1-A. There were no second trimester pregnancies in group 1-B. Miscarriage rate in group 2-A was significantly lower compared to group 2-B (P < 0.01), although CPR did not show any significant differences between the groups. A no-triple line endometrial pattern with moderate endometrial thickness (7-14 mm) had a detrimental effect on pregnancy outcome, but not the occurrence of pregnancy. In group 3, there was no difference in CPR and miscarriage rates between the two patterns; adequate endometrial thickness (>14 mm) seemed to mitigate the detrimental impact (high miscarriage rate) of pattern B. Combined analysis of endometrial thickness and pattern on the day of hCG administration was a better predictor of the outcome of IVF/ICSI-ET and may be more helpful for patient counseling than the separate analyses.

The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P < 0.05), anal exhaust time (78.8 ± 9.3 vs 85.3 ± 8.4 h, P < 0.05), and length of hospitalization (7.73 ± 2.13 vs 9.77 ± 1.76 days, P < 0.01) differed significantly. Treatment costs in thousands of dol-lars were 31.24 ± 3.21 for the experimental group and 35.61 ± 2.32 for the control group; this difference was statistically significant (P < 0.01). The incidence of postoperative complications did not significantly differ between the experimental and control groups [14.0% (21/150) vs 17.3% (26/150), P > 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P < 0.05). CD8(+) cell counts were significantly lower in the experimental group than the control group (P < 0.05). Postsurgical oral EEN can improve nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

To determine whether vitamin E would slow the progression of cognitive deterioration and dementia in aging persons with Down syndrome (DS). A randomized, double-blind controlled clinical trial was conducted at 21 clinical sites, and researchers trained in research procedures recruited adults with DS older than 50 years to participate. Participants were randomly assigned to receive 1,000 IU of vitamin E orally twice daily for 3 years or identical placebo. The primary outcome was change on the Brief Praxis Test (BPT). Secondary outcomes included incident dementia and measures of clinical global change, cognition, function, and behavior. A total of 337 individuals were randomized, 168 to vitamin E and 169 to placebo. Both groups demonstrated deterioration on the BPT with no difference between drug and placebo. At baseline, 26% were diagnosed with dementia and there was an overall rate of incident dementia of 11%/year with no difference between groups. There was no effect on the secondary outcome measures. Though numerically higher in the treatment group, there was no difference in the number of adverse events (p = 0.079) and deaths (p = 0.086) between groups. Vitamin E did not slow the progression of cognitive deterioration in older individuals with DS. This study provides Class II evidence that vitamin E does not significantly slow the progression of cognitive deterioration in aging persons with DS. © 2016 American Academy of Neurology.

While evidence continues to accumulate on the relevance of cognitive inflexibility in anorexia nervosa (AN), its clinical correlates remain unclear. We aimed at examining the relationship between set-shifting and clinical variables (i.e., eating psychopathology, depression, and personality) in AN. Ninety-four individuals affected by AN and 59 healthy controls (HC) were recruited. All participants were assessed using: Eating Disorders Inventory-2 (EDI-2), Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and Wisconsin Card Sorting Test (WCST). The AN group scored worse than HCs on set-shifting. According to their neuropsychological performances, AN patients were split into two groups corresponding to poor (N=30) and intact (N=64) set-shifting subtypes. Interoceptive awareness, impulse regulation, and maturity fears on the EDI-2 and depression on the BDI differed across all groups (HC, intact, and poor set-shifting subtype). Self-directedness on the TCI differed significantly among all groups. Cooperativeness and reward dependence differed instead only between HC and AN poor set-shifting subtype. After controlling for depression, only interoceptive awareness remained significant with reward dependence showing a trend towards statistical significance. These findings suggest that multiple clinical variables may be correlated with set-shifting performances in AN. The factors contributing to impaired cognitive inflexibility could be more complex than heretofore generally considered. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The aim of this trial was to evaluate the effects of polyunsaturated fatty acid (PUFA) supplementation in different-stages atopic dogs fed on a controlled diet. Twenty-two non-seasonal atopic dogs of different breeds and ages were included in the 2-month trial. All the patients were given an essential fatty acid (EFA) supplementation [17 mg/kg eicosapentaenoic acid (EPA) + 5 mg/kg docosahexaenoic acid (DHA) + 35 mg/kg gammalinolenic acid (GLA)], the global (diet + supplementation) omega-6 to omega-3 ratio was 5.5-1. Two groups of dogs were considered: group A 'pre-immunotherapy' (15 cases) included dogs with early stages atopy, which had not been submitted to any treatment yet; group B 'post-immunotherapy' (seven cases) included dogs with chronic atopy immunotherapy non-responsive. Clinical evaluations were performed at the beginning, on day 30 and at the end of the trial. Blood serum fatty acids profile was determined at the beginning and at the end of the study. Better clinical results were obtained in group A, a great difference was found between the two groups on pruritus score. Serum arachidonic acid (AA) was significantly lower at the end of the trial in group A while GLA was significantly higher in group B. We hypothesized that different-stages atopic dogs could have different response to EFA supplementation, maybe because of a different fatty acids metabolism. Early stages cases seem to be more responsive to EFA supplementation.

The purpose of this study was to assess the metabolic profile of plasma samples from cows with clinical and subclinical ketosis. According to clinical signs and 3-hydroxybutyrate plasma levels, 81 multiparous Holstein cows were selected from a dairy farm 7 to 21 d after calving. The cows were divided into 3 groups: cows with clinical ketosis, cows with subclinical ketosis, and healthy control cows. (1)H-Nuclear magnetic resonance-based metabolomics was used to assess the plasma metabolic profiles of the 3 groups. The data were analyzed by principal component analysis, partial least squares discriminant analysis, and orthogonal partial least-squares discriminant analysis. The differences in metabolites among the 3 groups were assessed. The orthogonal partial least-squares discriminant analysis model differentiated the 3 groups of plasma samples. The model predicted clinical ketosis with a sensitivity of 100% and a specificity of 100%. In the case of subclinical ketosis, the model had a sensitivity of 97.0% and specificity of 95.7%. Twenty-five metabolites, including acetoacetate, acetone, lactate, glucose, choline, glutamic acid, and glutamine, were different among the 3 groups. Among the 25 metabolites, 4 were upregulated, 7 were downregulated, and 14 were both upregulated and downregulated. The results indicated that plasma (1)H-nuclear magnetic resonance-based metabolomics, coupled with pattern recognition analytical methods, not only has the sensitivity and specificity to distinguish cows with clinical and subclinical ketosis from healthy controls, but also has the potential to be developed into a clinically useful diagnostic tool that could contribute to a further understanding of the disease mechanisms.

Clinical training programs increasingly use entrustable professional activities (EPAs) as focus of assessment. However, questions remain about which information should ground decisions to trust learners. This qualitative study aimed to identify decision variables in the workplace that clinical teachers find relevant in the elaboration of the entrustment decision processes. The findings can substantiate entrustment decision-making in the clinical workplace. Focus groups were conducted with medical and veterinary clinical teachers, using the structured consensus method of the Nominal Group Technique to generate decision variables. A ranking was made based on a relevance score assigned by the clinical teachers to the different decision variables. Field notes, audio recordings and flip chart lists were analyzed and subsequently translated and, as a form of axial coding, merged into one list, combining the decision variables that were similar in their meaning. A list of 11 and 17 decision variables were acknowledged as relevant by the medical and veterinary teacher groups, respectively. The focus groups yielded 21 unique decision variables that were considered relevant to inform readiness to perform a clinical task on a designated level of supervision. The decision variables consisted of skills, generic qualities, characteristics, previous performance or other information. We were able to group the decision variables into five categories: ability, humility, integrity, reliability and adequate exposure. To entrust a learner to perform a task at a specific level of supervision, a supervisor needs information to support such a judgement. This trust cannot be credited on a single case at a single moment of assessment, but requires different variables and multiple sources of information. This study provides an overview of decision variables giving evidence to justify the multifactorial process of making an entrustment decision.

To compare efficacy of female sterilization by modified Uchida technique and silver clips and to evaluate the influence on operation procedure and clinical effect with or without surgery training of service providers. A comparative, multicenter clinical trial was performed in 18 county and township-level service centers. Totally 2198 women underwent sterilization from these 18 study center were divided into 1116 women sterilized by modified Uchida technique and 1082 women by silver clips. Those 18 centers were classified into 9 training groups which provide surgical skills of sterilization and other contents and 9 non training groups. Clinical documents of sterilization were recorded. All women were follow-up at 3, 6 and 12 months after surgery. There were no complications during surgery by both sterilization. The failure rate was 2.03% (22/1082) in silver clip method and the mean operative time were (12.4 ± 6.4) minutes in training group and (14.4 ± 8.1) minutes in non training group. In modified Uchida method, the failure rate was 0.18% (2/1116) and the mean operative time were (16.2 ± 4.9) minutes in training group and (19.0 ± 8.6) minutes in non training group. The mean operative time between two groups reached statistical difference (all P < 0.05). Total ended rate in modified Uchida technique were 2.2/hundred women year in training group and 2.5/hundred women year in non training group, and the rate of silver slips were 3.9/hundred women year and 4.8/hundred women year, which did not show significant difference (all P > 0.05). There was no significant difference in acceptability and side effects of all women between two methods (P > 0.05). The training of service providers could influence acceptability of women (P < 0.05). Clinical efficacy was not influenced by those two methods. The operative time and acceptability were improved by training surgeons in silver clips method.

Background: Acute exacerbations of chronic bronchitis (AECB) are defined as recurrent attacks of worsening bronchial inflammation that are marked by an increase in the volume of daily sputum produced, a change in color of the expectorated sputum, and worsening dyspnea. Farcosolvin® (Pharco Pharmaceuticals, Alexandria, Egypt) is a mixture of ambroxol (15 mg); theophylline (50 mg); and guaiphenesin (30 mg), per 5 mL syrup. Objective: To test the clinical efficacy of Farcosolvin in the treatment of AECB in a randomized, single-blinded, controlled study design. Patients and methods: One hundred patients with AECB were randomized to either Farcosolvin or guaiphenesin treatment groups, in addition to the standard medical treatment for their cases. Baseline clinical symptomatolgy of breathlessness, cough, and sputum severity scoring were compared before and after 3 and 7 days of treatment in both groups and the differences compared between groups. Changes in perceived improvement were also compared between groups using the Clinical Global Impression of Improvement or Change Scale (CGIC). Results: There were statistically significant improvements in breathlessness and cough scores in both groups (pretreatment versus posttreatment at day 3 and at day 7; P < 0.05). There were highly statistically significant differences between groups in improvement in breathlessness and cough scores, after 3 and 7 days treatment, in favor of the Farcosolvin treatment group (P < 0.001). Out of 50 patients, 48 (96%) in the Farcosolvin-treated group rated their improvement on the CGIC scale as “much” and “very much” improved, while only 41 patients (82%) reported such a degree of improvement in the control group. The difference was statistically significant (P < 0.05). Conclusion: We concluded from our study that Farcosolvin syrup might be safe and effective in improving symptoms in cases of acute exacerbation of chronic bronchitis. PMID:20714379

This pilot study was designed to evaluate the impact of a pre-rotation workshop (PRW) on pharmacy students' clinical skills and preparation for clinical Advanced Pharmacy Practice Experiences (APPE) involving direct patient care. Randomized controlled trial of an educational intervention with Institutional Review Board approval. PRW activities designed to simulate rotation activities around five competencies, patient charts, medication histories, SOAP notes, patient presentations, and professionalism. Endpoints were evaluated using clinical rotation preceptors' evaluation of performance and students' performance on objective structured clinical exams (OSCE). Eight fourth-year students and eight GPA matched controls (20% of the total class) were selected to voluntarily participate. The PRW demonstrated a positive impact on students' clinical skills and preparation for rotations by improving OSCE performance. However, no significant differences were found between groups when comparing preceptor evaluations of skills on rotations. These results are limited by the small sample size, potential OSCE "test-wiseness" effects, lack of OSCE evaluator blinding to study groups, potential case specificity effects due to the limited number of cases used on the OSCE and possible lack of sensitivity of the rotation evaluation tool to capture true differences among the experimental and control group participants. The PRW was successful at advancing students' clinical skills and preparation for rotations and may be considered as a tool to help bridge didactic to clinical experiences in the Pharm.D. curriculum.

Mozambique suffers from critical shortages of healthcare workers including non-physician clinicians, Tecnicos de Medicina Geral (TMGs), who are often senior clinicians in rural health centres. The Mozambique Ministry of Health and the International Training and Education Center for Health, University of Washington, Seattle, revised the national curriculum to improve TMG clinical knowledge and skills. To evaluate the effort, data was collected at graduation and 10 months later from pre-revision (initial) and revised curriculum TMGs to determine the following: (1) Did cohorts trained in the revised curriculum score higher on measurements of clinical knowledge, physical exam procedures, and solving clinical case scenarios than those trained in the initial curriculum; (2) Did TMGs in both curricula retain their knowledge over time (from baseline to follow-up); and (3) Did skills and knowledge retention differ over time by curricula? Post-graduation and over time results are presented. t-tests examine differences in scores between curriculum groups. Univariate and multivariate linear regression models assess curriculum-related, demographic, and workplace factors associated with scores on each of three evaluation methods at the p < 0.05 level. Paired t-tests examine within-group changes over time. ANOVA models explore differences between Health Training Institutes (HTIs). Generalized estimating equations determine whether change in scores over time differed by curricula. Mean scores of initial curriculum TMGs at follow-up were 52.7%, 62.6%, and 40.0% on the clinical cases, knowledge test, and physical exam, respectively. Averages were significantly higher among the revised group for clinical cases (60.2%; p < 0.001) and physical exam (47.6%; p < 0.001). HTI was influential on clinical case and physical exam scores. Between graduation and follow-up, clinical case and physical exam scores decreased significantly for initial curriculum students; clinical case scores increased significantly among revised curriculum TMGs. Although curriculum revision had limited effect, marginal improvements in the revised group show promise that these TMGs may have increased ability to synthesize clinical information. Weaknesses in curriculum and practicum implementation likely compromised the effect of curriculum revision. An improvement strategy that includes strengthened TMG training, greater attention to pre-service clinical practice, and post-graduation mentoring may be more advantageous than curriculum revision, alone, to improve care provided by TMGs.

We derived sample size formulae for detecting main effects in group-based randomized clinical trials with different levels of data hierarchy between experimental and control arms. Such designs are necessary when experimental interventions need to be administered to groups of subjects whereas control conditions need to be administered to individual subjects. This type of trial, often referred to as a partially nested or partially clustered design, has been implemented for management of chronic diseases such as diabetes and is beginning to emerge more commonly in wider clinical settings. Depending on the research setting, the level of hierarchy of data structure for the experimental arm can be three or two, whereas that for the control arm is two or one. Such different levels of data hierarchy assume correlation structures of outcomes that are different between arms, regardless of whether research settings require two or three level data structure for the experimental arm. Therefore, the different correlations should be taken into account for statistical modeling and for sample size determinations. To this end, we considered mixed-effects linear models with different correlation structures between experimental and control arms to theoretically derive and empirically validate the sample size formulae with simulation studies.

The changing face of Usher syndrome: clinical implications.

PubMed

Cohen, Mazal; Bitner-Glindzicz, Maria; Luxon, Linda

2007-02-01

Usher syndrome is both genetically and phenotypically heterogeneous. Traditionally, the condition has been classified into three clinical types, differentiated by the severity and progression of the hearing impairment and by the presence or absence of vestibular symptoms. Recent advances in molecular genetics have enabled researchers to study the phenotypic expression in confirmed molecular groups of Usher. In response to the expansion of clinical and genetic information on Usher, we report an up to date review of the different clinical forms of Usher in known molecular groups and use the emerging evidence to appraise the diagnostic utility of the traditional classification of Usher. Our findings undermine the traditional view that the clinical types of Usher have distinct genetic causes. The pleiotropic effects of some of the major causes of Usher lead to considerable overlap between the different clinical types, with very little evidence for phenotypic-genotypic correlations. The novel synthesis emerging from this review suggests more productive approaches to the diagnosis of Usher in hearing-impaired children which would provide more accurate prognostic information to families.

The aim of this study was to evaluate whether there are clinical subgroups that may have different prognoses among FMF patients. The cumulative clinical features of a large group of FMF patients [1168 patients, 593 (50.8%) male, mean age 35.3 years (s.d. 12.4)] were studied. To analyse our data and identify groups of FMF patients with similar clinical characteristics, a two-step cluster analysis using log-likelihood distance measures was performed. For clustering the FMF patients, we evaluated the following variables: gender, current age, age at symptom onset, age at diagnosis, presence of major clinical features, variables related with therapy and family history for FMF, renal failure and carriage of M694V. Three distinct groups of FMF patients were identified. Cluster 1 was characterized by a high prevalence of arthritis, pleuritis, erysipelas-like erythema (ELE) and febrile myalgia. The dosage of colchicine and the frequency of amyloidosis were lower in cluster 1. Patients in cluster 2 had an earlier age of disease onset and diagnosis. M694V carriage and amyloidosis prevalence were the highest in cluster 2. This group of patients was using the highest dose of colchicine. Patients in cluster 3 had the lowest prevalence of arthritis, ELE and febrile myalgia. The frequencies of M694V carriage and amyloidosis were lower in cluster 3 than the overall FMF patients. Non-response to colchicine was also slightly lower in cluster 3. Patients with FMF can be clustered into distinct patterns of clinical and genetic manifestations and these patterns may have different prognostic significance. © The Author 2015.

To evaluate the demographic and clinical manifestations and postsurgical outcome of childhood-onset mesial temporal sclerosis and temporal lobe epilepsy (MTS-TLE) and establishing the potential differences as compared to the patients with adult-onset MTS-TLE. In this retrospective study all patients with a clinical diagnosis of medically refractory TLE due to mesial temporal sclerosis, who underwent epilepsy surgery at Jefferson comprehensive epilepsy center, were recruited. Patients were prospectively registered in a database from 1986 through 2014. Postsurgical outcome was classified into two groups; seizure-free or relapsed. Clinical manifestations and outcome were compared between patients with childhood-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure below 10 years) and those with adult-onset MTS-TLE (i.e., age at onset of the first afebrile habitual seizure 20 years or above). One hundred and twelve patients had childhood-onset MTS-TLE and 76 had adult-onset MTS-TLE. Demographic, clinical, EEG and MRI characteristics of these two groups were similar. Postoperative outcome was not statistically different between these two groups of patients (P=0.9). Temporal lobe epilepsy due to mesial temporal sclerosis is a common cause of epilepsy that can start from early childhood to late adulthood. The etiology of MTS-TLE may be different in various age groups, but it seems that when mesial temporal sclerosis is the pathological substrate of TLE, clinical manifestations and response to surgical treatment of patients are very similar in patients with childhood-onset MTS-TLE compared to those with adult-onset disease.

The primary aim of the study was to examine stability and alignment after total knee arthroplasty (TKA) using patient-specific instrumentation (PSI) and conventional instrumentation (CI). The hypothesis was that stability and alignment would be better using PSI than CI, 12 months postoperatively. The secondary aim included the evaluation of clinical outcomes after TKA. In this prospective randomized controlled trial, 42 patients with knee osteoarthritis received a Genesis II PS prosthesis with either PSI or CI. Patients visited the hospital preoperatively and postoperatively after 6 weeks and 3 and 12 months. To evaluate stability, varus-valgus laxity was determined in extension and flexion using stress radiographs 12 months postoperatively. Three months postoperatively, a long-leg radiograph and CT scan were obtained to measure hip-knee-ankle (HKA) alignment and component rotation. Furthermore, frontal and sagittal alignment of the components, the Knee Society Score, VAS Pain, VAS Satisfaction, Knee injury and Osteoarthritis Outcome score, Patella score (Kujala), University of California Los Angeles activity score, anterior-posterior laxity, (serious) adverse device-related events, and intraoperative complications were reported. The clinical outcomes were compared using independent t tests or non-parametric alternatives, and repeated measurements ANOVA with a significance level of p < 0.05. No significant differences were found between the two groups regarding stability, HKA angle, and rotational alignment. In four patients, the PSI did not fit correctly on the tibia and/or femur requiring intraoperative modifications. Both groups improved significantly over time on all clinical outcomes, with no significant differences between the groups 12 months postoperatively. The PSI group showed less tibial slope than the patients in the CI group [PSI 2.6° versus CI 4.8° (p = 0.02)]. Finally, the PSI group more frequently received a thinner insert size than the CI group (p = 0.03). Patients operated with PSI did not differ from CI in terms of stability and alignment. However, in the PSI group ligament releases were more often required intraoperatively. Furthermore, the two methods did not show different clinical results. It seems that the preoperative planning for the PSI facilitates more conservative bone cuts than CI, but whether this is clinically relevant should be investigated. Since PSI is more expensive and time consuming than CI, and does not outperform CI with regard to clinical results, we recommend to use CI. I.

Differences in the presentation of clinical features of body dysmorphic disorder (BDD) across ethnic groups have received little investigation. The current study assessed BDD symptoms in an ethnically diverse sample of adults (n=401) using an online survey. Participants completed self-report measures assessing BDD symptoms, body parts of concern and BDD behaviors. Compared to Caucasian participants, no significant differences were found in body parts or behaviors reported by Latino or African American participants. Significant group differences did emerge between Asian and Caucasian participants. Specifically, Asians reported more concern with straight hair and dark skin and fewer body shape concerns than Caucasians. Asians also endorsed lower rates of grooming, touching body parts, and camouflaging and higher rates of exercise compared to Caucasians. Although most clinical features of BDD appear similar across ethnic groups, results showed some differences in body parts and behaviors between Caucasians and Asian Americans with BDD symptoms.

The aim of the study was to evaluate whether intermittent fasting (IF) is an effective preventive measure, and whether it is feasible for healthy volunteers under every day conditions. A nonrandomized controlled clinical trial on IF was performed with healthy volunteers over a period of 8 wk, and a subsequent 4-mo follow-up. Outcomes were assessed at baseline, after 8 wk, and after 6 mo. Volunteers who were not interested in fasting served as a control group. Participants in the fasting group were asked to continue their regular nutritional habits on the nonfasting days, whereas the control group maintained their habitual nutrition throughout the whole period. Outcomes included changes of metabolic parameters (insulin, glucose, insulin resistance, insulin-like growth factor-1, brain-derived neurotropic factor, lipids, liver enzymes, hemoglobin A1c) and coagulation markers; bioelectrical impedance analysis; body mass index; abdominal girth; blood pressure; general quality of life (five-item World Health Organization Well-Being Index [WHO-5] questionnaire), as well as mood and anxiety (Hospital Anxiety and Depression Scale [HADS], Profile of Mood States, Flourishing-Scale, visual analog scale, Likert scales). The intervention consisted of a fasting day, which was repeated every week for 8 wk, with abstinence from solid food between 00:00 and 23:59 at minimum and a maximum caloric intake of 300 kcal on each fasting day. A per-protocol analysis was performed. P < 0.05 was considered significant. Thirty-six volunteers were included; 22 allocated themselves to the fasting group, and 14 to the control group. Thirty-three data sets were included in the final analysis. Although significant in-group changes were observed in both groups for a number of outcomes after 8 wk and 6 mo, no significant between-group differences were observed for any outcome other than overall body fat mass after 8 wk as well as for the HADS total score and the WHO-5 total score after 6 mo, all in favor of the fasting group. However, none of the between-group differences were clinically relevant. We did not find any clinically relevant differences between groups in this controlled clinical pilot trial of 8 wk of IF in healthy volunteers. Further clinical research in this field is warranted to further analyze mechanisms and effects of IF. Copyright © 2017 Elsevier Inc. All rights reserved.

Enhancing nursing students' critical thinking is a challenge faced by nurse educators. This study aimed at determining the effect of clinical concept mapping on discipline-based critical thinking of nursing students. In this quasi-experimental post-test only design, a convenient sample of 4(th) year nursing students (N = 32) participated. They were randomly divided into two groups. The experimental group participated in a 1-day workshop on clinical concept mapping. They were also assigned to use at least two clinical concepts mapping during their clinical practice. Post-test was done using a specially designed package consisting of vignettes for measurement of 17 dimensions of critical thinking in nursing under two categories of cognitive critical thinking skills and habits of mind. They were required to write about how they would use a designated critical thinking skills or habits of mind to accomplish the nursing actions. The students' responses were evaluated based on identification of critical thinking, justification, and quality of the student's response. The mean score of both groups was compared by Mann-Whitney test using SPSS version 16.5. The results of the study revealed a significant difference between the two groups' critical thinking regarding identification, justification, and quality of responses, and overall critical thinking scores, cognitive thinking skills, and habits of mind. The two groups also differed significantly from each other in 11 out of 17 dimensions of critical thinking. Clinical concept mapping is a valuable strategy for improvement of critical thinking of nursing students. However, further studies are recommended to generalize this result to nursing students in their earlier stage of education.

To evaluate whether clinical anxiety in children presenting to a pediatric pain management center is associated with a poorer treatment response for those who completed pain-focused cognitive behavioral therapy (CBT). The total sample consisted of 175 children, 40 of whom completed CBT for chronic pain. The Screen for Child Anxiety Related Emotional Disorders was completed at initial evaluation and outcome measures (average pain intensity and the Functional Disability Inventory) were collected during the initial evaluation and at the end of CBT. Group differences in outcomes were examined following CBT. The role of anxiety in CBT initiation and completion was also explored. Presence of clinical anxiety was associated with greater initiation and/or completion of pain-focused CBT but also a poorer treatment response. Specifically, the group with subclinical anxiety exhibited a substantial reduction in pain intensity, and the group with clinical anxiety exhibited a more limited response to treatment (F [1, 36] = 13.68 P < .01). A similar effect was observed for Functional Disability Inventory, such that the group with clinical anxiety had a significantly smaller response to treatment (F [1, 38] = 4.33 P < .05). The difference in pain and disability between groups following CBT suggest moderate effects (Cohen d = 0.77 and 0.78, respectively). Although youths with clinical anxiety are more likely to start and/or complete pain-focused CBT, anxiety has an adverse impact on CBT treatment response in children with chronic pain. Identification of patients with anxiety and use of tailored behavioral interventions may improve clinical outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

Adapting Social Neuroscience Measures for Schizophrenia Clinical Trials, Part 2: Trolling the Depths of Psychometric Properties

Kern, Robert S.

2013-01-01

The psychometric properties of 4 paradigms adapted from the social neuroscience literature were evaluated to determine their suitability for use in clinical trials of schizophrenia. This 2-site study (University of California, Los Angeles and University of North Carolina) included 173 clinically stable schizophrenia outpatients and 88 healthy controls. The social cognition battery was administered twice to the schizophrenia group (baseline, 4-week retest) and once to the control group. The 4 paradigms included 2 that assess perception of nonverbal social and action cues (basic biological motion and emotion in biological motion) and 2 that involve higher level inferences about self and others’ mental states (self-referential memory and empathic accuracy). Each paradigm was evaluated on (1) patient vs healthy control group differences, (2) test-retest reliability, (3) utility as a repeated measure, and (4) tolerability. Of the 4 paradigms, empathic accuracy demonstrated the strongest characteristics, including large between-group differences, adequate test-retest reliability (.72), negligible practice effects, and good tolerability ratings. The other paradigms showed weaker psychometric characteristics in their current forms. These findings highlight challenges in adapting social neuroscience paradigms for use in clinical trials.

Impairments in willingness to exert effort contribute to the motivational deficits characteristic of the negative symptoms of schizophrenia. The current study evaluated the psychometric properties of 5 new or adapted paradigms to determine their suitability for use in clinical trials of schizophrenia. This study included 94 clinically stable participants with schizophrenia and 40 healthy controls. The effort-based decision-making battery was administered twice to the schizophrenia group (baseline, 4-week retest) and once to the control group. The 5 paradigms included 1 that assesses cognitive effort, 1 perceptual effort, and 3 that assess physical effort. Each paradigm was evaluated on (1) patient vs healthy control group differences, (2) test-retest reliability, (3) utility as a repeated measure (ie, practice effects), and (4) tolerability. The 5 paradigms showed varying psychometric strengths and weaknesses. The Effort Expenditure for Rewards Task showed the best reliability and utility as a repeated measure, while the Grip Effort Task had significant patient-control group differences, and superior tolerability and administration duration. The other paradigms showed weaker psychometric characteristics in their current forms. These findings highlight challenges in adapting effort and motivation paradigms for use in clinical trials.

The color of dental porcelain depends on the type of metal substrate. Little research has been done to document the effects of different types of high-palladium alloys on the color of dental porcelain. The purpose of this in vitro study was to evaluate the effects of different high-palladium alloys on the resulting color of dentin porcelain, as well as on that of opaque porcelain after simulated dentin and glazing firing cycles. Three Pd-Cu-Ga alloys, Spartan Plus (S), Liberty (B), and Freedom Plus (F), and 5 Pd-Ga alloys, Legacy (L), IS 85 (I), Protocol (P), Legacy XT (X), and Jelenko No.1 (N), were examined. A Pd-Ag alloy, Super Star (T), was included for comparison to the high-palladium alloys, and the Au-Pd alloy, Olympia (O), served as the control. Six cast discs (16 x 1 mm) were prepared from each of the alloys. Shade B1 opaque porcelain (Vita-Omega) was applied at a final thickness of 0.1 mm. After 2 opaque porcelain firing cycles, the surfaces were airborne-particle abraded, and the specimens were divided into 2 groups. In the first group, 0.9 mm of B1 dentin porcelain was applied. The other group of specimens with only opaque porcelain underwent the same dentin porcelain and glazing firing cycles. Color differences (DeltaE) were determined with a colorimeter between the control and each experimental group, after the second opaque porcelain, second dentin porcelain, and glazing firing cycles. One-way analysis of variance and Dunnett's multiple range test were performed on the DeltaE data (alpha=.05). After the application of dentin porcelain, the 3 Pd-Cu-Ga alloys showed significantly different (P<.05) DeltaE values (S=2.3 +/- 0.5, B=1.4 +/- 0.3, and F=1.3 +/- 0.7) than the control group. After the glazing cycle of this group, the 3 Pd-Cu-Ga alloys and the Pd-Ag alloy exhibited significantly different (P<.05) DeltaE values (S=2.8 +/- 0.8, B=2.2 +/- 0.3, F=1.9 +/- 1.0, and T=1.4 +/- 0.5) than the control group. After the simulated dentin porcelain firing cycles, the specimens with only opaque porcelain exhibited significantly different (P<.05) DeltaE values (S=5.2 +/- 1.4, B=5.4 +/- 0.6, and F=3.9 +/- 0.2) than the control group. The color difference between the 3 Pd-Cu-Ga alloys with only opaque porcelain and the control group increased more after the simulated glazing cycle (S=6.6 +/- 1.5, B=6.3 +/- 0.5, and F=4.6 +/- 0.1). The observed color differences between the Pd-Ga alloys and the control group were not statistically significant at any point. The Pd-Cu-Ga alloys with only opaque porcelain, after the simulated dentin porcelain and glazing firing cycles, exhibited clinically unacceptable color differences. The application of dentin porcelain to the Pd-Cu-Ga alloys resulted in clinically acceptable color differences. The application of dentin porcelain to the Pd-Ag alloy, after the glazing firing cycle, resulted in clinically acceptable color differences (approximately 2.8 to 3.7 DeltaE CIELAB units). The Pd-Ag alloy specimens with only opaque porcelain did not exhibit significant color differences from the control group, whereas significant color differences from the control group after the dentin porcelain and glazing firing cycles were still clinically acceptable.

The use of adjuncts like chlorhexidine local delivery and diode laser decontamination have been found to improve the clinical outcomes of scaling and root planing in non-surgical periodontal therapy in patients with chronic periodontitis. To evaluate the effects of diode laser and chlorhexidine chip as adjuncts to scaling and root planing in the management of chronic periodontitis. The objective is to evaluate the outcome of chlorhexidine chip and diode laser as adjuncts to scaling and root planing on clinical parameters like Plaque Index, Gingival Index, probing pocket depth and clinical attachment level. Department of Periodontics. Randomized clinical trial with split mouth design. Fifteen chronic periodontitis patients having a probing pocket depth of 5mm-7mm on at least one interproximal site in each quadrant of the mouth were included in the study. After initial treatment, four sites in each patient were randomly subjected to scaling and root planing (control), chlorhexidine chip application (CHX chip group), diode laser (810 nm) decontamination (Diode laser group) or combination of both (Diode laser and chip group). Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD) and clinical attachment level (CAL) were assessed at baseline, one month and three months. Results were statistically analysed using paired T test, one-way ANOVA, Tukey's HSD test and repeated measure ANOVA. Post-treatment, the test and control sites showed a statistically significant reduction in PI, GI, PPD, and CAL. After three months, a mean PPD reduction of 1.47±0.52 mm in control group, 1.40±0.83 mm in diode laser group, 2.67±0.62 mm in CHX group, and 2.80± 0.77 mm in combination group was seen. The mean gain in CAL were 1.47±0.52 mm in the control group, 1.40±0.83 mm in diode laser group, 2.67± 0.49 mm in CHX group and 2.67± 0.82 mm in combination group respectively. The differences in PPD reduction and CAL gain between control group and CHX chip and combination groups were statistically significant (p<0.05) at three months, whereas, the diode laser group did not show any significant difference from the control group. Chlorhexidine local delivery alone or in combination with diode laser decontamination is effective in reducing probing pocket depth and improving clinical attachment levels when used as adjuncts to scaling and root planing in non-surgical periodontal therapy of patients with chronic periodontitis.

Introduction The use of adjuncts like chlorhexidine local delivery and diode laser decontamination have been found to improve the clinical outcomes of scaling and root planing in non-surgical periodontal therapy in patients with chronic periodontitis. Aim To evaluate the effects of diode laser and chlorhexidine chip as adjuncts to scaling and root planing in the management of chronic periodontitis. The objective is to evaluate the outcome of chlorhexidine chip and diode laser as adjuncts to scaling and root planing on clinical parameters like Plaque Index, Gingival Index, probing pocket depth and clinical attachment level. Study and Design Department of Periodontics. Randomized clinical trial with split mouth design. Materials and Methods Fifteen chronic periodontitis patients having a probing pocket depth of 5mm-7mm on at least one interproximal site in each quadrant of the mouth were included in the study. After initial treatment, four sites in each patient were randomly subjected to scaling and root planing (control), chlorhexidine chip application (CHX chip group), diode laser (810 nm) decontamination (Diode laser group) or combination of both (Diode laser and chip group). Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD) and clinical attachment level (CAL) were assessed at baseline, one month and three months. Statistical analysis Results were statistically analysed using paired T test, one-way ANOVA, Tukey’s HSD test and repeated measure ANOVA. Results Post-treatment, the test and control sites showed a statistically significant reduction in PI, GI, PPD, and CAL. After three months, a mean PPD reduction of 1.47±0.52 mm in control group, 1.40±0.83 mm in diode laser group, 2.67±0.62 mm in CHX group, and 2.80± 0.77 mm in combination group was seen. The mean gain in CAL were 1.47±0.52 mm in the control group, 1.40±0.83 mm in diode laser group, 2.67± 0.49 mm in CHX group and 2.67± 0.82 mm in combination group respectively. The differences in PPD reduction and CAL gain between control group and CHX chip and combination groups were statistically significant (p<0.05) at three months, whereas, the diode laser group did not show any significant difference from the control group. Conclusion Chlorhexidine local delivery alone or in combination with diode laser decontamination is effective in reducing probing pocket depth and improving clinical attachment levels when used as adjuncts to scaling and root planing in non-surgical periodontal therapy of patients with chronic periodontitis.

The kidney is a major target organ for systemic amyloidosis, which results in proteinuria and an elevated serum creatinine level. The clinical manifestations and precursor proteins of amyloid A (AA) and light-chain (AL) amyloidosis are different, and the renal damage due to amyloid deposition also seems to differ. The purpose of this study was to clarify haw the difference in clinical features between AA and AL amyloidosis are explained by the difference in the amount and distribution of amyloid deposition in the renal tissues. A total of 119 patients participated: 58 patients with an established diagnosis of AA amyloidosis (AA group) and 61 with AL amyloidosis (AL group). We retrospectively investigated the correlation between clinical data, pathological manifestations, and the area occupied by amyloid in renal biopsy specimens. In most of the renal specimens the percentage area occupied by amyloid was less than 10%. For statistical analyses, the percentage area of amyloid deposition was transformed to a common logarithmic value (Log 10 %amyloid). The results of sex-, age-, and Log 10 %amyloid-adjusted analyses showed that systolic blood pressure (SBP) was higher in the AA group. In terms of renal function parameters, serum creatinine, creatinine clearance (Ccr) and estimated glomerular filtration rate (eGFR) indicated significant renal impairment in the AA group, whereas urinary protein indicated significant renal impairment in the AL group. Pathological examinations revealed amyloid was predominantly deposited at glomerular basement membrane (GBM) and easily transferred to the mesangial area in the AA group, and it was predominantly deposited at in the AL group. The degree of amyloid deposition in the glomerular capillary was significantly more severe in AL group. The frequency of amyloid deposits in extraglomerular mesangium was not significantly different between the two groups, but in AA group, the degree amyloid deposition was significantly more severe, and the deposition pattern in the glomerulus was nodular. Nodular deposition in extraglomerular mesangium leads to renal impairment in AA group. There are significant differences between AA and AL amyloidosis with regard to the renal function, especially in terms of Ccr, eGFR and urinary protein, even after Log10%amyloid was adjusted; showing that these inter-group differences in renal function would not be depend on the amount of renal amyloid deposits. These differences could be explained by the difference in distribution and morphological pattern of amyloid deposition in the renal tissue.

Comparison of the Mortality and In-Hospital Outcomes of Preterm Infants Treated with Ibuprofen for Patent Ductus Arteriosus with or without Clinical Symptoms Attributable to the Patent Ductus Arteriosus at the Time of Ibuprofen Treatment

The aim of this study was to assess the differences in the mortality and in-hospital outcomes of preterm infants with < 28 weeks of gestation who received ibuprofen treatment according to the presence of clinical symptoms (any of oliguria, hypotension, or moderate to severe respiratory difficulty) attributable to hemodynamically-significant patent ductus arteriosus (hsPDA) at the time of first ibuprofen treatment. In total, 91 infants born from April 2010 to March 2015 were included. Fourteen infants (15.4%) received ibuprofen treatment when there were clinical symptoms due to hsPDA (clinical symptoms group). In clinical symptoms group, infants were younger (25 [23–27] vs. 26 [23–27] weeks; P = 0.012) and lighter (655 [500–930] vs. 880 [370–1,780] grams; P < 0.001). Also, the clinical risk index for babies (CRIB)-II scores were higher and more infants received invasive ventilator care ≤ 2 postnatal days. More infants received multiple courses of ibuprofen in clinical symptoms group. Although the frequency of secondary patent ductus arteriosus (PDA) ligation and the incidence of bronchopulmonary dysplasia (BPD) was higher in the clinical symptoms group in the univariate analysis, after multivariate logistic regression analysis adjusting for the CRIB-II score, birthweight, birth year, and the invasive ventilator care ≤ 2 postnatal days, there were no significant differences in mortality, frequency of secondary ligation and in-hospital outcomes including necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), BPD or death. Our data suggest that we can hold off on PDA treatment until the clinical symptoms become prominent. PMID:27914140

Training programs for resident surgeons represent a challenge for the mentoring activity. The aim of the present study is to investigate the impact of our training program for laparoscopic cholecystectomy on patient's safety and on the modulation of the residents' exposure to clinical scenario with different grades of complexity. This is a retrospective study based on a clinical series of laparoscopic cholecystectomy performed in a teaching hospital. Study population was grouped according to the expertise of the attending primary operator among resident surgeons. Four groups were identified: consultant (C), senior resident (SR); intermediate level resident (IR); junior resident (JR). The intraoperative and postoperative outcomes were confronted to evaluate the patient's safety profile. 447 patients were submitted to LC: 96 cases were operated by a C, 200 by SR, 112 by IR and 39 by JR. The mean operative time was the longest for the JR group. A statistically higher rate of conversion to open approach was registered in C and IR groups in comparison to JR and SR groups. However, in C and IR groups, patients had worse ASA score, higher BMI and more frequent past history of previous abdominal surgery, cholecystitis or pancreatitis. Overall, it was not registered any statistically significant difference among the groups in terms of length of hospital stay and prevalence of major postoperative complications. Applying an educational model based on both graduated levels of responsibility and modulated grade of clinical complexity can guarantee an high safety profile.

Asian Americans and Pacific Islanders are twice as likely to be diagnosed with type 2 diabetes compared to Caucasians. The objective was to determine the effect of cognitive behavioral therapy on quality of life, general health perceptions, depressive symptoms, and glycemia in Asians and Pacific Islanders with type 2 diabetes. The design was a randomized controlled clinical trial comparing cognitive behavioral therapy to diabetes education and support for six weekly sessions. Participants were recruited from two endocrinology practices; 207 were enrolled. The cognitive behavioral therapy group was provided self-management tools which included biofeedback, breathing exercises, and stress relievers, while the diabetes education and support group included diabetes education and group discussions. Assessments of psychosocial and clinical outcomes were obtained before and after sessions and 12 months PostSession. Differences between the two groups were examined using linear mixed-effects models with linear contrasts. The cognitive behavioral therapy group had improved depressive symptom scores from PreSession to EndSession compared to the diabetes education and support group (P < .03), but the improvement did not extend to 12 months PostSession. Similar results were observed with misguided support scores in the Multidimensional Diabetes Questionnaire (P < .03) and susceptibility in health beliefs (P < .01), but no significant differences in HbA1c improvement were found between the two groups. Both interventions improved outcomes from baseline but were not sustained for 1 year.

To evaluate the efficacy of the five ear acupuncture points (Shen-men, Spleen, Stomach, Hunger, Endocrine), generally used in Korean clinics for treating obesity, and compare them with the Hunger acupuncture point. A randomised controlled clinical trial was conducted in 91 Koreans (16 male and 75 female, body mass index (BMI)≥23), who had not received any other weight control treatment within the past 6 months. Subjects were divided randomly into treatment I, treatment II or sham control groups and received unilateral auricular acupuncture with indwelling needles replaced weekly for 8 weeks. Treatment I group received acupuncture at the five ear acupuncture points, treatment II group at the Hunger acupuncture point only and the sham control group received acupuncture at the five ear acupuncture points used in treatment I, but the needles were removed immediately after insertion. BMI, waist circumference, weight, body fat mass (BFM), percentage body fat and blood pressure were measured at baseline and at 4 and 8 weeks after treatment. For the 58 participants who provided data at 8 weeks, significant differences in BMI, weight and BFM were found between the treatment and control groups. Treatment groups I and II showed 6.1% and 5.7% reduction in BMI, respectively (p<0.004). There were no significant differences between the two treatment groups. This finding suggests that the five ear acupuncture points, generally used in Korean clinics, and the Hunger point alone treatment are both effective for treating overweight people.

The present randomized controlled trial was conducted to evaluate acellular dermal matrix (ADM) graft in terms of patient satisfaction and its effectiveness and efficiency in the treatment of gingival recession. Fourteen patients (seven males and seven females) with Miller Class I and II recessions > or =3 mm participated in this 6-month clinical study. They were assigned randomly to the ADM group (ADM graft and coronally positioned flap [CPF]) or the CPF group (CPF alone). Results were evaluated based on parameters measuring patient satisfaction and clinical outcomes associated with the two treatment procedures. Significance was set at P <0.05. The mean recession was 4.0 +/- 1.0 mm and 3.7 +/- 0.7 mm for the ADM and CPF groups, respectively. For the ADM group, the defect coverage was 3.85 +/- 0.89 mm or 97.14% compared to the CPF group, in which the defect coverage was 2.85 +/- 0.89 mm or 77.42%. The difference between the two groups was statistically significant (P <0.05). There were no statistically significant differences between the two groups in the remaining clinical parameters and overall patient satisfaction except in criteria related to patient comfort and cost effectiveness, in which CPF alone produced significantly better results (P <0.03). ADM graft is significantly superior with regard to effectiveness and efficiency in the treatment of gingival recession than CPF alone. CPF emerges as a better option than ADM graft in terms of cost effectiveness and patient comfort.

This study was designed to measure job satisfaction among registered clinical dentists so as to identify issues which may influence recruitment and retention of dentists in active clinical practice. A questionnaire measuring dimensions of job satisfaction was mailed to a stratified random sample of 80 private and 80 public sector dentists selected from the 1999 Victorian Dental Register. An adjusted response rate of 60 per cent was achieved (n = 87). Analyses showed significant differences (ANOVA; p < 0.05) in levels of satisfaction for various dimensions of job satisfaction by gender, age group and practice type. Differences in job satisfaction between male and female dentists related to the personal time dimension. Differences in satisfaction between dentists of different age groups were attributable to six dimensions: relationships with colleagues, relationships with patients, relationships with staff, personal time, community and administrative responsibilities. Differences between levels of satisfaction among private and public dentists related to the autonomy, relationships with patients, pay and resources dimensions. There are various dimensions of job satisfaction that may be pertinent to issues influencing recruitment and retention of dentists. Differences that exist between levels of job satisfaction among private and public sector dentists, between male and female dentists and dentists of different age groups need to be addressed in order to improve recruitment and retention rates of dentists in active clinical practice in different sectors of the dental care system.

The aim of this study was to compare the effect of two sugar-substituted chewing gums besides toothbrushing on different clinical, microbiological, and biochemical caries- and gingivitis-related variables. The study was designed as a double-blind, randomized, controlled trial with three parallel arms. A total of 130 dental students, who volunteered after signing an informed consent, were randomly allocated to receive one of the following interventions: hexitol-sweetened gum containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), pentitol-sweetened gum containing no CPP-ACP, and control group with no gum. Subjects within the experimental groups chewed two gum pellets for 20 min three times a day after meals. The daily consumption level of both polyols was 6.0 g. Clinical examinations and salivary samplings were conducted at baseline and after 30 days of gum use. Pre- and post-intervention stimulated whole saliva samples were quantified for calcium/phosphate ionic concentration, total facultative bacterial load, Streptococcus mutans/Lactobacillus spp. counts, and Gram-negative percentage. A statistically significant reduction in visible plaque score was displayed in the hexitol/CPP-ACP gum group after the intervention when compared with baseline, but the order of the effect was in the same order as the differences between the groups at baseline. A similar tendency was seen in both the pentitol/non-CPP-ACP gum and control groups regarding total salivary facultative bacterial load and S. mutans count, but median values of these parameters were more significantly reduced in the pentitol/non-CPP-ACP gum group in comparison with those of the control group. Alterations of salivary Lactobacillus spp. were demonstrated only in the pentitol/non-CPP-ACP gum group. Although these findings might indicate that a 30-day protocol of daily chewing of pentitol-sweetened gum containing no CPP-ACP might have some a reducing effect on the salivary levels of facultative bacteria, S. mutans and Lactobacillus spp., there was only a marginal, if any, benefit from the chewing gums under study on some microbiological caries- and gingivitis-related variables. Taking into account that for transferring results into clinically relevant conclusions the findings need to be strong and consistent, adhering to single significant differences appears not appropriate. Hence, the clinical significance of chewing gums as an adjunctive tool for daily oral care remained questionable.

The utility of the focused assessment with sonography for trauma (FAST) examination in children is unknown. To determine if the FAST examination during initial evaluation of injured children improves clinical care. A randomized clinical trial (April 2012-May 2015) that involved 975 hemodynamically stable children and adolescents younger than 18 years treated for blunt torso trauma at the University of California, Davis Medical Center, a level I trauma center. Patients were randomly assigned to a standard trauma evaluation with the FAST examination by the treating ED physician or a standard trauma evaluation alone. Coprimary outcomes were rate of abdominal computed tomographic (CT) scans in the ED, missed intra-abdominal injuries, ED length of stay, and hospital charges. Among the 925 patients who were randomized (mean [SD] age, 9.7 [5.3] years; 575 males [62%]), all completed the study. A total of 50 patients (5.4%, 95% CI, 4.0% to 7.1%) were diagnosed with intra-abdominal injuries, including 40 (80%; 95% CI, 66% to 90%) who had intraperitoneal fluid found on an abdominal CT scan, and 9 patients (0.97%; 95% CI, 0.44% to 1.8%) underwent laparotomy. The proportion of patients with abdominal CT scans was 241 of 460 (52.4%) in the FAST group and 254 of 465 (54.6%) in the standard care-only group (difference, -2.2%; 95% CI, -8.7% to 4.2%). One case of missed intra-abdominal injury occurred in a patient in the FAST group and none in the control group (difference, 0.2%; 95% CI, -0.6% to 1.2%). The mean ED length of stay was 6.03 hours in the FAST group and 6.07 hours in the standard care-only group (difference, -0.04 hours; 95% CI, -0.47 to 0.40 hours). Median hospital charges were $46 415 in the FAST group and $47 759 in the standard care-only group (difference, -$1180; 95% CI, -$6651 to $4291). Among hemodynamically stable children treated in an ED following blunt torso trauma, the use of FAST compared with standard care only did not improve clinical care, including use of resources; ED length of stay; missed intra-abdominal injuries; or hospital charges. These findings do not support the routine use of FAST in this setting. clinicaltrials.gov Identifier: NCT01540318.

The purpose was to compare immediate intramammary antimicrobial treatment of all cases of clinical mastitis with a selective treatment protocol based on 24-h culture results. The study was conducted at a 3,500-cow commercial farm in New York. Using a randomized design, mild to moderate clinical mastitis cases were assigned to either the blanket therapy or pathogen-based therapy group. Cows in the blanket therapy group received immediate on-label intramammary treatment with ceftiofur hydrochloride for 5 d. Upon receipt of 24 h culture results, cows in the pathogen-based group followed a protocol automatically assigned via Dairy Comp 305 (Valley Agricultural Software, Tulare, CA): Staphylococcus spp., Streptococcus spp., or Enterococcus spp. were administered on-label intramammary treatment with cephapirin sodium for 1 d. Others, including cows with no-growth or gram-negative results, received no treatment. A total of 725 cases of clinical mastitis were observed; 114 cows were not enrolled due to severity. An additional 122 cases did not meet inclusion criteria. Distribution of treatments for the 489 qualifying events was equal between groups (pathogen-based, n = 246; blanket, n = 243). The proportions of cases assigned to the blanket and pathogen-based groups that received intramammary therapy were 100 and 32%, respectively. No significant differences existed between blanket therapy and pathogen-based therapy in days to clinical cure; means were 4.8 and 4.5 d, respectively. The difference in post-event milk production between groups was not statistically significant (blanket therapy = 34.7 kg; pathogen-based = 35.4 kg). No differences were observed in test-day linear scores between groups; least squares means of linear scores was 4.3 for pathogen-based cows and 4.2 for blanket therapy cows. Odds of survival 30 d postenrollment was similar between groups (odds ratio of pathogen-based = 1.6; 95% confidence interval: 0.7-3.7) as was odds of survival to 60 d (odds ratio = 1.4; 95% confidence interval: 0.7-2.6). The one significant difference found for the effect of treatment was in hospital days; pathogen-based cows experienced, on average, 3 fewer days than blanket therapy cows. A majority (68.5%) of moderate and mild clinical cases would not have been treated if all cows on this trial were enrolled in a pathogen-based protocol. The use of a strategic treatment protocol based on 24-h postmastitis pathogen results has potential to efficiently reduce antimicrobial use. Copyright © 2017 American Dairy Science Association.

Chronic kidney disease (CKD) is the convergent point of several pathological processes, and its evolution is insidious and characterized by a progressive and irreversible loss of kidney function. This impaired function induces the accumulation of uremic toxins and individuals with terminal CKD often have altered physiological responses, including a persistent state of immuno-suppression and development of diseases. A better characterization and stratification of these patients with CKD in different immuno-compromised groups would contribute to more effective and personalized treatments. The focus of this study was to use two parameters to stratify patients with CKD into four separate groups that are representative of different immunological status. Patients with CKD were chosen randomly and stratified into four separate groups according to the period of time receiving dialysis treatment and leukocyte blood counts. The amount of apoptotic CD4 T cells were measured in each group of patients, and clinical/hematological parameters were correlated by multivariate analysis with each group. Observations reveal that one of the four groups of patients with CKD (group 3) had more apoptotic CD4 T cells than the other group; this group also had an increased malnutrition inflammation score (MIS), an elevated Kt/V, and a higher incidence of smoking. A simple two-parameter-based stratification strategy could be used to design effective immunological therapies that differentiate the degrees of immuno-suppression across groups of patients with CKD. © 2018 Wiley Periodicals, Inc.

Intraventricular hemorrhage (IVH) is associated with high morbidity and mortality. This study evaluated the safety and efficacy of the combined treatment of an Ommaya reservoir and conventional external ventricular drainage (EVD) using urokinase in the management of IVH. We performed a prospective controlled study. Sixty eligible patients with IVH received conventional EVD alone (group A) or combined EVD and Ommaya reservoir (group B) between January 2010 and January 2015. Clinical, cerebrospinal fluid, and radiographic data were used to assess clot clearance, clinical outcomes, and complications between the groups. There were no significant differences in gender, age, blood pressure, Glasgow Coma Scale, Graeb score, intracerebral hemorrhage volume on admission, and IVH volume before surgery between groups A and B (P > 0.05). The number of injections of urokinase (20,000 IU/dose) were significantly different in group B compared with group A (P < 0.05). Repeated computed tomography scans 3 days, 6 days, and 10 days after surgery revealed that clot clearance rates at each time point were significantly increased in group B compared with group A (P < 0.05). The conventional catheter-based EVD duration time was shortened to 5 (4-6) days in group B compared with 7 (5-9) days in group A (P < 0.05). The total drainage time was prolonged to 9 (8-11) days in group B compared with 7 (5-9) days in group A (P < 0.05). Ventriculitis was not significantly different between the 2 groups (P > 0.05). The hydrocephalus incidence and mortality revealed significant differences between the 2 groups (P < 0.05). The 30-day Glasgow Outcome Scale score was significantly increased in group B compared with group A (P < 0.05). The combined treatment approach of an Ommaya reservoir and EVD with intraventricular urokinase is safe and effective in patients with IVH. It increased clot clearance, shortened conventional catheter-based EVD duration, prolonged total drainage time, reduced the hydrocephalus incidence and mortality, and contributed to good clinical outcomes. The Ommaya reservoir provides a safe way to increase the injection times of urokinase, which accelerated clot resolution and did not increase the risk for ventriculitis infection.

Arthroscopic rotator cuff repair has become popular in the last few years because it avoids large skin incisions and deltoid detachment and dysfunction. Earlier arthroscopic single-row (SR) repair methods achieved only partial restoration of the original footprint of the tendons of the rotator cuff, while double-row (DR) repair methods presented many biomechanical advantages and higher rates of tendon-to-bone healing. However, DR repair failed to demonstrate better clinical results than SR repair in clinical trials. MR imaging at 3 Tesla, especially with intra-articular contrast medium (MRA), showed a better diagnostic performance than 1.5 Tesla in the musculoskeletal setting. The objective of this study was to retrospectively evaluate the clinical and 3 Tesla MRA results in two groups of patients operated on for a medium-sized full-thickness rotator cuff tear with two different techniques. The first group consisted of 20 patients operated on with the SR technique; the second group consisted of 20 patients operated on with the DR technique. All patients were evaluated at a minimum of 3 years after surgery. The primary end point was the re-tear rate at 3 Tesla MRA. The secondary end points were the Constant-Murley Scale (CMS), the Simple Shoulder Test (SST) scores, surgical time and implant expense. The mean follow-up was 40 months in the SR group and 38.9 months in the DR group. The mean postoperative CMS was 70 in the SR group and 68 in the DR group. The mean SST score was 9.4 in the SR group and 10.1 in the DR group. The re-tear rate was 60% in the SR group and 25% in the DR group. Leakage of the contrast medium was observed in all patients. To the best of our knowledge, this is the first report on 3 Tesla MRA in the evaluation of two different techniques of rotator cuff repair. DR repair resulted in a statistically significant lower re-tear rate, with longer surgical time and higher implant expense, despite no difference in clinical outcomes. We think that leakage of the contrast medium is due to an incomplete tendon-to-bone sealing, which is not a re-tear. This phenomenon could have important medicolegal implications. Level of evidence III. Treatment study: Case-control study.

A comparison of different treatment modalities of peri-implantitis can lead to the development and application of more effective and efficient methods of therapy in clinical practice. This study compares the effectiveness of open flap debridement used alone, with an approach employing the additional use of a diode laser for the treatment of peri-implantitis. Nineteen patients were divided into two groups and treated for peri-implantitis. In the control group (C group), the therapy utilized access flaps, plastic curettes, and sterilized gauzes soaked in saline. The test group (L group) was treated similarly but with additional irradiation using a diode laser. The parameters studied were pocket depth (PD) as the primary outcome variable, clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) as secondary variables. Measurements were performed at three different time points, baseline (BSL), 3 months, and 6 months after treatment. Three months after treatment, a mean PD reduction of 1.19 mm for the control group and 1.38 mm for the laser group was recorded. The corresponding BOP changes were 72.9 and 66.7%, respectively. These changes were significant and remained at the same levels at the 6-month examination (p < 0.05). CAL was reduced significantly only in group L from 5.25 mm at baseline to 4.54 mm at 3 months, remaining at this level at 6 months (p < 0.05). PI was reduced significantly in group C at 3 months from 37.5 to 6.3%. The 6-month data showed no statistically significant difference (p < 0.05) from the 3-month measurements. The two methods of therapy for peri-implantitis examined seemed to be equally efficient in the reduction of the PD and BOP 3 months after surgery, with the results sustained at the same levels after 6 months. CAL significantly improved only in the test group after 3 months. PI was reduced and maintained at low levels in both groups. Surgical treatment of peri-implantitis by access flaps leads to improvement of all clinical parameters studied while the additional use of diode laser does not seem to have an extra beneficiary effect. The additional use of a diode laser in the surgical treatment of peri-implantitis offers a limited clinical benefit.

Hypertension is a major risk factor for cardiovascular disease and prevalence varies by ethnic group. The diagnosis and management of blood pressure are informed by guidelines largely based on data from white populations. This study addressed whether accuracy of blood pressure measurement in terms of diagnosis of hypertension varies by ethnicity by comparing two measurement modalities (clinic blood pressure and home monitoring) with a reference standard of ambulatory BP monitoring in three ethnic groups. Cross-sectional population study (June 2010 - December 2012) with patients (40-75 years) of white British, South Asian and African Caribbean background with and without a previous diagnosis of hypertension recruited from 28 primary care practices. The study compared the test performance of clinic BP (using various protocols) and home-monitoring (1 week) with a reference standard of mean daytime ambulatory measurements using a threshold of 140/90 mmHg for clinic and 135/85 mmHg for out of office measurement. A total of 551 participants had complete data of whom 246 were white British, 147 South Asian and 158 African Caribbean. No consistent difference in accuracy of methods of blood pressure measurement was observed between ethnic groups with or without a prior diagnosis of hypertension: for people without hypertension, clinic measurement using three different methodologies had high specificity (75-97%) but variable sensitivity (33-65%) whereas home monitoring had sensitivity of 68-88% and specificity of 64-80%. For people with hypertension, detection of a raised blood pressure using clinic measurements had sensitivities of 34-69% with specificity of 73-92% and home monitoring had sensitivity (81-88%) and specificity (55-65%). For people without hypertension, ABPM remains the choice for diagnosing hypertension compared to the other modes of BP measurement regardless of ethnicity. Differences in accuracy of home monitoring and clinic monitoring (higher sensitivity of the former; higher specificity of the latter) were also not affected by ethnicity.

We prospectively assessed the early radiographic and clinical outcomes (minimum follow-up of 2 years) of robot-assisted pedicle screw fixation (Robot-PSF) and conventional freehand pedicle screw fixation (Conv-PSF). Patients were randomly assigned to Robot-PSF (37 patients) or Conv-PSF (41 patients) for posterior interbody fusion surgery. The Robot-PSF group underwent minimally invasive pedicle screw fixation using a pre-planned robot-guided screw trajectory. The Conv-PSF underwent screw fixation using the freehand technique. Radiographic adjacent segment degeneration (ASD) was measured on plain radiographs, and clinical outcomes were measured using visual analogue scale (VAS) and Oswestry disability index (ODI) scores regularly after surgery. The two groups had similar values for radiographic ASD, including University California at Los Angeles grade, vertebral translation, angular motion, and loss of disc height (p=0.320). At final follow-up, both groups had experienced significant improvements in back VAS, leg VAS, and ODI scores after surgery (p<0.001), although inter-group differences were not significant for back VAS (p=0.876), leg VAS (p=0.429), and ODI scores (p=0.952). In the Conv-PSF group, revision surgery was required for two of the 25 patients (8%), compared to no patients in the Robot-PSF group. There were no significant differences in radiographic ASD and clinical outcomes between Robot-PSF and Conv-PSF. Thus, the advantages of robot-assisted surgery (accurate pedicle screw insertion and minimal facet joint violation) do not appear to be clinically significant. © Copyright: Yonsei University College of Medicine 2018.

Objective To compare presentation of Alzheimer disease (AD) at the time of initial evaluation at a university specialty clinic across three ethnoracial groups in order to understand similarities and differences in the demographic, clinical, cognitive, psychiatric, and biologic features. Design Cross-sectional study. Participants A total of 1,341 self-identified African American, Latino (primarily of Caribbean origin), and white non-Hispanic (“WNH”) subjects were recruited from primary care sites or by referral by primary care physicians. Measurements Demographic variables and age of onset of AD, as well as cognitive, functional, and mood impairments at the time of initial presentation and frequencies of apolipoprotein E genotypes, were compared across groups. Results Differences among ethnoracial groups were found for nearly all variables of interest. In particular, the largely immigrant Puerto Rican Latino group had an earlier age of onset of AD, more cognitive impairment, and greater severity of cognitive impairment at the time of initial evaluation in the setting of low average education and socioeconomic status. There was more depression in the Latinos compared with African Americans and WNHs. Greater severity of symptoms was not accounted for by a difference in lag time between onset of symptoms and initial evaluation. The apolipoprotein E-4 genotype was not associated with AD in the Latino cohort. Conclusions Minority groups in Philadelphia, especially Latinos, exhibit a more severe profile of AD at the time of presentation than WNHs. Important potential confounds need to be considered and future research comparing immigrant and nonimmigrant Latino groups will be necessary to elucidate the highly significant differences reported.

Sexual difficulty has various effects on patients suffering from this condition that can impact on interpersonal and marital relationships. Sexual function may be adversely affected by stress of any kind and emotional disorders. There have been limited studies focusing on the mental health of those suffering from this problem. To determine the relationship between sexual difficulties and mental health in female patients seeking help in psychiatric clinics. The study was based on the case-control design methodology in which the case group consisted of 165 outpatients of two psychiatric clinics, who were diagnosed with different mental disorders such as depression, anxiety, phobia, aggression, and somatic complaints (33 subjects for each type of disorder). The 33 subjects in the control group were chosen among the patients' relatives and visitors who had no history of either seeking psychiatric help or taking psychiatric drugs. The subjects of both case and control groups were selected based on a convenience sampling method. Moreover, the data were collected based on two techniques of "interview" and "questionnaire;" the latter was of three different subcategories, each dealt with demographic characteristics, sexual difficulties, and a Symptom Check-List-90-Revised. Assessing female sexual difficulties associated with mental health and differences between women with and without psychiatric problems. The obtained results indicated that there was a significant difference between the prevalence of sexual difficulties (e.g., sexual desire and orgasm disorders) in the case group and that of the control group. It was also revealed that there was a significant difference between the depressed, aggressive, as well as those with somatic complaints, and their control group counterparts. In Iran, sexual difficulties seem to be more frequent in those seeking psychiatric help in clinics than in those within the normal population.

The authors assess the long-term safety and efficacy of cervical disc replacement with the Prestige Cervical Disc in a prospective, randomized, multicenter trial at 7 years of follow-up. At 31 investigational sites, 541 patients with single-level cervical disc disease with radiculopathy were randomized to 1 of 2 treatment groups: 276 investigational group patients underwent anterior cervical discectomy and arthroplasty with the Prestige disc, and 265 control group patients underwent anterior cervical discectomy and fusion. Clinical outcomes included Neck Disability Index, the 36-Item Short-Form Health Survey, and neck and arm pain scores. Radiographs were assessed for angle of motion and fusion. Clinical and radiographic outcomes were evaluated preoperatively, intraoperatively, and at 1.5, 3, 6, 12, 24, 36, 60, and 84 months. Of the 541 patients treated, 395 patients (73%; 212 investigational and 183 control patients) completed 7 years of clinical follow-up. Significant improvements achieved by 1.5 months in both groups were sustained at 7 years. In the investigational group, mean Neck Disability Index improvements from preoperative scores were 38.2 and 37.5 at 60 and 84 months, respectively. In the control group, the corresponding means were 33.8 and 31.9. The differences between the investigational and control groups at the 60-month and 84-month periods were significant (p = 0.014 and 0.002, respectively). The overall rates of maintenance or improvement in neurological status in the investigational group were significantly higher: 92.2% and 88.2% at 60 months and 84 months, respectively, compared with 85.7% and 79.7% in the control group (p = 0.017 and 0.011, respectively). At 84 months, the percentage of working patients in the investigational group was 73.9%, and in the control group, 73.1%. Postoperatively, the implant effectively maintained average angular motion of 6.67° at 60 months and 6.75° at 84 months. Cumulative rates for surgery at the index level were lower (p < 0.001) in the investigational group (11 [4.8%] of 276) when compared with the control group (29 [13.7%] of 265) (based on life-table method), and there were statistical differences between the investigational and control groups with specific regard to the rate of subsequent revision and supplemental fixation surgical procedures. Rates for additional surgical procedures that involved adjacent levels were lower in the investigational group than in the control group (11 [4.6%] of 276 vs. 24 [11.9%] of 265, respectively). Cervical disc arthroplasty has the potential for preserving motion at the operated level while providing biomechanical stability and global neck mobility and may result in a reduction in adjacent-segment degeneration. The Prestige Cervical Disc maintains improved clinical outcomes and segmental motion after implantation at 7-year follow-up. Clinical trial registration no. NCT00642876 ( ClinicalTrials.gov ).

Despite some preliminary evidence, it is still largely unknown whether osteopathic manipulative treatment improves preterm clinical outcomes. The present multi-center randomized single blind parallel group clinical trial enrolled newborns who met the criteria for gestational age between 29 and 37 weeks, without any congenital complication from 3 different public neonatal intensive care units. Preterm infants were randomly assigned to usual prenatal care (control group) or osteopathic manipulative treatment (study group). The primary outcome was the mean difference in length of hospital stay between groups. A total of 695 newborns were randomly assigned to either the study group (n= 352) or the control group (n=343). A statistical significant difference was observed between the two groups for the primary outcome (13.8 and 17.5 days for the study and control group respectively, p<0.001, effect size: 0.31). Multivariate analysis showed a reduction of the length of stay of 3.9 days (95% CI -5.5 to -2.3, p<0.001). Furthermore, there were significant reductions with treatment as compared to usual care in cost (difference between study and control group: 1,586.01€; 95% CI 1,087.18 to 6,277.28; p<0.001) but not in daily weight gain. There were no complications associated to the intervention. Osteopathic treatment reduced significantly the number of days of hospitalization and is cost-effective on a large cohort of preterm infants.

Abstract Megalencephaly and macrocephaly present with a head circumference measurement 2 standard deviations above the age-related mean. However, even if pathologic events resulting in both megalencephaly and macrocephaly may coexist, a distinction between these two entities is appropriate, as they represent clinical expression of different disorders with a different approach in clinical work-up, overall prognosis, and treatment. Megalencephaly defines an increased growth of cerebral structures related to dysfunctional anomalies during the various steps of brain development in the neuronal proliferation and/or migration phases or as a consequence of postnatal abnormal events. The disorders associated with megalencephaly are classically defined into 3 groups: idiopathic or benign, metabolic, and anatomic. In this article, we seek to underline the clinical aspect of megalencephaly, emphasizing the main disorders that manifest with this anomaly in an attempt to properly categorize these disorders within the megalencephaly group.

This randomized split-mouth clinical trial was designed to evaluate the efficacy of scaling and root planing associated to the high-intensity diode laser on periodontal therapy by means of clinical parameters and microbial reduction. A total of 36 chronic periodontitis subjects, of both genders, were selected. One pair of contralateral single-rooted teeth with pocket depth >5 mm was chosen from each subject. All patients received non-surgical periodontal treatment, after which the experimental teeth were designated to either test or control groups. Both teeth received scaling, root planing and coronal polishing (SRP) and teeth assigned to the test group (SRP + DL) were irradiated with the 808 ± 5 nm diode laser, for 20 s, in two isolated appointments, 1 week apart. The laser was used in the continuous mode, with 1.5 W and power density of 1,193.7 W/cm(2). Clinical and microbiological data were collected at baseline, 6 weeks and 6 months after therapy. There was a significant improvement of all the clinical parameters-clinical attachment level (CAL), probing depth (PD), plaque index (PI) and Bleeding on Probing (BOP)-for both groups (P < 0.001), with no statistical difference between them at the 6 weeks and the 6 months examinations. As for microbiological analysis, a significant reduction after 6 weeks (P > 0.05) was observed as far as colony forming units (CFU) is concerned, for both groups. As for black-pigmented bacteria, a significant reduction was observed in both groups after 6 months. However, the difference between test and control groups was not significant. There was no association between group and presence of Porphyromonas gingivalis, Prevotella intermedia and Aggregatibacter actinomycetemcomitans at any time of the study. After 6 months of evaluation, the high-intensity diode laser has not shown any additional benefits to the conventional periodontal treatment. The high intensity diode laser did not provide additional benefits to non-surgical periodontal treatment. More studies are necessary to prove the actual need of this type of laser in the periodontal clinical practice.

Virtual patient simulation has grown substantially in health care education. A virtual patient simulation was developed as a refresher training course to reinforce nursing clinical performance in assessing and managing deteriorating patients. The objective of this study was to describe the development of the virtual patient simulation and evaluate its efficacy, by comparing with a conventional mannequin-based simulation, for improving the nursing students' performances in assessing and managing patients with clinical deterioration. A randomized controlled study was conducted with 57 third-year nursing students who were recruited through email. After a baseline evaluation of all participants' clinical performance in a simulated environment, the experimental group received a 2-hour fully automated virtual patient simulation while the control group received 2-hour facilitator-led mannequin-based simulation training. All participants were then re-tested one day (first posttest) and 2.5 months (second posttest) after the intervention. The participants from the experimental group completed a survey to evaluate their learning experiences with the newly developed virtual patient simulation. Compared to their baseline scores, both experimental and control groups demonstrated significant improvements (P<.001) in first and second post-test scores. While the experimental group had significantly lower (P<.05) second post-test scores compared with the first post-test scores, no significant difference (P=.94) was found between these two scores for the control group. The scores between groups did not differ significantly over time (P=.17). The virtual patient simulation was rated positively. A virtual patient simulation for a refreshing training course on assessing and managing clinical deterioration was developed. Although the randomized controlled study did not show that the virtual patient simulation was superior to mannequin-based simulation, both simulations have demonstrated to be effective refresher learning strategies for improving nursing students' clinical performance. Given the greater resource requirements of mannequin-based simulation, the virtual patient simulation provides a more promising alternative learning strategy to mitigate the decay of clinical performance over time.

To compare the clinical traits in comorbidity between depression and neurological disorder with depressive disorder and explore the characteristic of the outpatients with neurological disorder comorbidity in depression. According to Diagnosis and Statistic Manual for Mental Disorder-IV (DSM-IV) criteria, outpatients were diagnosed as depressive disorder at Departments of Neurology and Psychology. We used HAMD-17 scale to evaluate the patient's severity. There was no statistical difference in severity of depression in two groups. But the clinical traits showed significant differences between two outpatient groups: the outpatients with neurological disorder comorbidity in depression were elder, had more somatic disorders and a higher retard symptom factor score while the other are relative younger, have less physical disorders and higher the core symptom factor score on the other hand. The patients of comorbidity between depression and neurological disorders have unique clinical traits. Thus it will be helpful to improve the identification of diagnosis and choose an appropriate treatment if we know the differences well.

Photodynamic therapy (PDT) and imiquimod are the treatments of choice for actinic keratosis (AK). As they have different mechanisms of action, it seems reasonable to assume that applying both treatments sequentially would be efficacious. We sought to determine which of these therapeutic modalities provides a better clinical and histologic response in patients with AK and whether sequential use of both was more efficacious than each separately. Patients were randomly assigned to one treatment group: group 1, PDT only; group 2, imiquimod only; or group 3, sequential use of PDT and imiquimod. The primary outcome measure was complete clinical response. Partial clinical response was defined as a reduction of more than 75% in the initial number of lesions. A complete clinicopathologic response was defined as lack of evidence of AK in the biopsy specimen. In all, 105 patients completed the study (group 1, 40 patients; group 2, 33 patients; group 3, 32 patients). Sequential application of PDT and imiquimod was more efficacious in all the outcome measures. More patients were satisfied with PDT than with the other two modalities (P = .003). No significant differences were observed among the 3 modalities and tolerance to treatment. Only one cycle of imiquimod was administered. The follow-up period was brief. Sequential application of PDT and imiquimod provides a significantly better clinical and histologic response in the treatment of AK than PDT or imiquimod monotherapy. It also produces less intense local reactions and better tolerance and satisfaction than imiquimod monotherapy. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc.

To assess attitudes about career progress, resources for career development, and commitment to academic medicine in physician faculty at an academic medical center who spend more than 50% of their time in clinical care. Faculty survey. Academic medical center and associated Veterans Affairs medical center. A total of 310 physician faculty responded to the survey. Half of the faculty reported spending 50% or less of their time in clinical care (mean, 31% of time) (group 1) and half reported spending more than 50% of their time in clinical care (mean, 72% of time) (group 2). Group 2 faculty had one third of the time for scholarly activities, reported slower career progress, and were less likely to be at the rank of professor (40% and 16% for groups 1 and 2, respectively; P<.001) or to be tenured (52% and 26%, respectively; P<.001) despite similar age and years on faculty. Group 2 faculty were 50% more likely to report that tenure and promotion criteria were not reviewed at their annual progress report (P =.003) and that they did not understand the criteria (P<.001). Group 2 faculty valued excellence in patient care over scholarship and national visibility. Group 2 faculty reported greater dissatisfaction with academic medicine and less commitment to a career in academic medicine. Physician faculty who spend more than 50% of their time in clinical care have less time, mentoring, and resources needed for development of an academic career. These obstacles plus differences in their attitudes about career success and recognition contribute to significant differences in promotion. These factors are associated with greater dissatisfaction with academic medicine and lower commitment to academic careers.

To detect the expressions of EMMPRIN and its ligand CyPA in gingival crevicular fluid (GCF) of chronic periodontitis (CP) patients and explore their possible relation to the status of periodontal inflammation. GCF of CP patients (group CP) and periodontitis-free patients with intact dentition (the control group) were collected and assayed for EMMPRIN and CyPA expressions by ELISA. The clinical periodontal status of these patients were examined. Statistical analysis was performed by use of SPSS 17.0 software package. Spearman's correlation analysis was utilized to determine the relationships between the expressions of EMMPRIN and CyPA in GCF and the clinical parameters. In addition, analysis of variance (ANOVA) was used for comparing the difference between group CP and the control group. In group CP, GCF volume was positively correlated with EMMPRIN total amount, CyPA total amount and some clinical periodontal indexes (GI,SBI,AL). EMMPRIN total amount was positively correlated with GCF volume, CyPA total amount and some of clinical periodontal indexes (GI,SBI,AL), but it was negatively correlated with smoking status (P<0.05). Moreover, CyPA total amount was positively correlated with GCF volume, EMMPRIN total amount and some of clinical periodontal indexes (GI,SBI,AL). In the control group,there were significant positive correlations among GCF volume, EMMPRIN total amount and CyPA total amount. The difference of GCF, EMMPRIN and CyPA between the 2 groups were statistically significant (P<0.05). EMMPRIN and its ligand CyPA in GCF of periodontitis-free patients with intact dentition and CP patients were all detected. As the progress of periodontal inflammation, GCF secretion increases, as well as the expressions of EMMPRIN and CyPA in GCF.

Although Roux-en-Y (R-Y) reconstruction after distal gastrectomy has several advantages, such as prevention of bile reflux into the remnant stomach, it is rarely used because of the technical difficulty. This prospective randomized clinical trial aimed to show the efficacy of a novel method of R-Y reconstruction involving the use of 2 circular staplers by comparing this novel method to Billroth-I (B-I) reconstruction. A total of 118 patients were randomly allocated into the R-Y (59 patients) and B-I reconstruction (59 patients) groups. R-Y anastomosis was performed using two circular staplers and no hand sewing. The primary end-point of this clinical trial was the reflux of bile into the remnant stomach evaluated using endoscopic and histological findings at 6 months after surgery. No significant differences in clinicopathological findings were observed between the 2 groups. Although anastomosis time was significantly longer for the patients of the R-Y group (P<0.001), no difference was detected between the 2 groups in terms of the total surgery duration (P=0.112). Endoscopic findings showed a significant reduction of bile reflux in the remnant stomach in the R-Y group (P<0.001), and the histological findings showed that reflux gastritis was more significant in the B-I group than in the R-Y group (P=0.026). The results of this randomized controlled clinical trial showed that compared with B-I reconstruction, R-Y reconstruction using circular staplers is a safe and feasible procedure. This clinical trial study was registered at www.ClinicalTrials.gov (registration No. NCT01142271).

Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder. Clinical care is complicated by variable age at onset and severity of hematologic symptoms. Recent advances in the molecular biology of FA have allowed us to investigate the relationship between FA genotype and the nature and severity of the clinical phenotype. Two hundred forty-five patients from all 7 known complementation groups (FA-A to FA-G) were studied. Mutations were detected in one of the cloned FANC genes in 169 patients; in the remainder the complementation group was assigned by cell fusion or Western blotting. A range of qualitative and quantitative clinical parameters was compared for each complementation group and for different classes of mutation. Significant phenotypic differences were found. FA-G patients had more severe cytopenia and a higher incidence of leukemia. Somatic abnormalities were less prevalent in FA-C, but more common in the rare groups FA-D, FA-E, and FA-F. In FA-A, patients homozygous for null mutations had an earlier onset of anemia and a higher incidence of leukemia than those with mutations producing an altered protein. In FA-C, there was a later age of onset of aplastic anemia and fewer somatic abnormalities in patients with the 322delG mutation, but there were more somatic abnormalities in patients with IVS4 + 4A --> T. This study indicates that FA patients with mutations in the FANCG gene and patients homozygous for null mutations in FANCA are high-risk groups with a poor hematologic outcome and should be considered as candidates both for frequent monitoring and early therapeutic intervention.

The effect of cassia fistula emulsion on pediatric functional constipation in comparison with mineral oil: a randomized, clinical trial

PubMed Central

2012-01-01

Background The prevalence of Pediatric Functional Constipation (FC) has been reported between 0.7% to 29.6%. This study was conducted to compare the laxative effect of cassia fistula emulsion (CFE) with mineral oil (MO) on FC. Cassia fistula is named in Traditional Iranian Medicine (TIM) as “Folus”. Materials and methods A randomized clinical trial was carried on 81 children (age range: 4–13 years) with FC, according to Rome III criteria in Amirkola Children’s Hospital, Babol, Iran. They received CFE or MO randomly for three weeks. CFE was produced according to the order of TIM references. Children were counted as improved when they exited from Rome III criteria of FC. Frequency of defecation, fecal incontinence, retentive posturing, severity of pain, consistency of stool and anal leakage of oily material were compared between the two groups and with baselines. An intent-to-treat analysis was used. Safety of drugs was assessed with the evaluation of clinical adverse effects. Results 41 children were assigned randomly to receive CFE and 40 children received MO. After three weeks of medication, 84% of children in CFE group and 50% in MO group (p = 0.002) exited from the criteria of FC, so called improved. All measurable criteria improved in both groups. The frequency of defecation in CFE group improved from 1.7 per week (before the study) to 10.6 per week (at the third week) while this parameter differed in MO group from 2 to 6.1 (p < 0.001). The severity of pain during defecation and consistency of stool improved significantly better in CFE group than MO group (p < 0.05), but there were not any significant differences between the two groups in fecal incontinence and retentive posturing. Anal leakage of oily material occurred as an important complication in MO group while the children in CFE group did not complaint it. Drug’s compliances were not significantly different in the two groups. CFE and MO did not cause clinically significant side effects. Conclusions CFE was most effective than MO in the 3-week treatment of children with FC. PMID:23351337

[The clinical predictors of heteroaggressive behaviour of the women serving sentence in penitentiary].

Shaklein, K N; Bardenshtein, L M; Demcheva, N K

To identify clinical predictors of heteroaggressive behavior. Three hundreds and three women serving sentence in a penal colony were examined using clinical, neurologic and statistical methods. The main group consisted of 225 women with heteroaggressive behavior, the control group included 78 women without aggressive behavior. Differences between the main and control groups in the structure of mental disorders and key syndromes were revealed. The authors conclude that the states with elements of dysphoria, dysthymia, decompensation of personality disorders, which are defined in the various forms of mental pathology, are the most significant predictors of heteroaggressive behavior in women in the penal colony.

Gut microbiota exerts a fundamental role on host physiology, and how extrinsic perturbations influence its composition has been increasingly examined. However, the effect of drinking water on gut microbiota is still poorly understood. In this study, we explored the response of mouse gut bacterial community (fecal and mucosa-adhered) to the ingestion of different types of drinking water. The experimental cohort was divided according to different water sources into four groups of mice that consumed autoclaved tap water (control group), water collected directly from a drinking water treatment plant, tap water, and commercial bottled mineral water. Differences among groups were observed, especially related to control group, which exhibited the smallest intra-group variation, and the largest distance from test groups on the last experimental day. Clinically important taxa, such as Acinetobacter and Staphylococcus, increased in feces of mice that drank tap water and in mucosa-adhered samples of animals from disinfected and tap water groups. Furthermore, statistical analyses showed that both time elapsed between samplings and water type significantly influenced the variation observed in the samples. Our results reveal that drinking water potentially affects gut microbiota composition. Additionally, the increase of typical drinking water clinically relevant and antibiotic resistance-associated bacteria in gut microbiota is a cause of concern. Copyright © 2017 Elsevier Ltd.

The aim of this study was to evaluate the risk factors between ipsilateral and contralateral reherniation and to compare the effectiveness of miniopen transforaminal lumbar interbody fusion (TLIF) with unilateral fixation for each group. From November 2007 to December 2014, clinical and radiographic data of each group (ipsilateral or contralateral reherniation) were collected and compared. Functional assessment (Visual Analog Scale (VAS) score and Japanese Orthopaedic Association (JOA)) and radiographic evaluation (fusion status, disc height, lumbar lordosis (LL), and functional spine unit (FSU) angle) were applied to compare surgical effect for each group preoperatively and at final followup. MacNab questionnaire was applied to further evaluate the satisfactory rate after the discectomy and fusion. No difference except pain-free interval was found between ipsilateral and contralateral groups. There was a significant difference in operative time between two groups. No differences were found in clinical and radiographic data for assessment of surgical effect between two groups. The satisfactory rate was decreasing in both groups with time passing after discectomy. Difference in pain-free interval may be a distinction for ipsilateral and contralateral reherniation. Miniopen TLIF with unilateral pedicle screw fixation can be a recommendable way for single level reherniation regardless of ipsilateral or contralateral reherniation. PMID:27885358

To study the clinical effect of "gelatamp" colloidal silver gelatin sponge on preventing dry socket after extracting the mandibular impacted teeth. 1350 teeth extracted from 976 patients who needed to extract the mandibular impacted teeth were divided into group A, group B and group C randomly. "Gelatamp" colloidal silver gelatin sponge was implanted into alveolar socket after teeth extraction in group A, with absorbable gelatin sponge was implanted into alveolar socket in group B and nothing was implanted into alveolar socket in group C. The incidence of dry socket was observed, the data was analyzed using SPSS10.0 software package. The incidence of dry socket was 0.44% in group A, 2% in group B and 4.44% in group C. There was significant difference in the incidence of dry socket between group A and group C(P<0.01). There was also significant difference between group B and group C(P<0.05) and between group A and group B(P<0.05). The results demonstrate that "gelatamp" colloidal silver gelatin sponge can prevent the occurrence of dry socket after teeth extraction, which is of wide clinical use.

Forty-eight patients treated by primary bilateral simultaneous total knee arthroplasty, in which one knee had a lateral release and the other did not, were evaluated clinically and roentgenographically from one to 12 years postoperatively. Thirty of these patients also had a technetium-99 bone scan. Mean clinical scores at the last follow-up examination were 90 for both groups. Roentgenographically, there were no subluxations, dislocations, or fractures in either group. There were two metal-backed patellae (one in each group) with signs of polyethylene wear and developed debris. Bone scans showed no difference between the two groups and no signs of osteonecrosis ofmore » the patella.« less
