    To investigate the relationship between electrocardiographic (ECG) abnormalities and left ventricular (LV) segmental hypertrophy and myocardial fibrosis assessed by cardiovascular magnetic resonance (CMR) in asymptomatic or mildly symptomatic patients with hypertrophic cardiomyopathy (HCM). 118 asymptomatic or mildly symptomatic patients with HCM were examined with late gadolinium enhancement (LGE) CMR, 12-lead ECG, and echocardiography. The distribution and magnitude of LV segmental hypertrophy and LGE were assessed and analyzed in relation to ECG abnormalities. Abnormal electrocardiograms were found in 113 of 118 (95%) patients. Negative T waves were associated with greater apical septal thickness (P = 0.009) and an increased ratio of LV septum to free wall thickness (P = 0.01). Giant negative T waves (GNT) were found in 19 patients (16%), and were associated with apical HCM (P < 0.001), greater apical thickness (P = 0.004), and increased ratio of LV apical to basal wall thickness (P < 0.001). However, no significant association was demonstrated between GNT and apical LGE (P = 0.71). Abnormal Q waves were associated with greater basal anteroseptal thickness (P = 0.001), maximal basal thickness (P = 0.004), and more segments with extensive LGE (>75% wall thickness involved) (P = 0.001). LV hypertrophy was related to greater LV mass (P = 0.002) and LV end diastolic volume (P = 0.002). In addition, a modest but significant correlation was observed between maximum LV wall thickness and the Romhilt-Estes score (r = 0.41, P < 0.001). GNT were associated with apical HCM and an increased ratio of LV apical to basal wall thickness. Abnormal Q waves were related to basal anteroseptal hypertrophy and segmental extensive LGE.

    (1) In patients with mildly symptomatic pulmonary hypertension (stage III), there is no firm evidence that ambrisentan reduces mortality or slows disease progression. In contrast, ambrisentan has frequent and sometimes serious adverse effects; (2) In patients whose physical activity is markedly restricted by pulmonary hypertension, it is better to continue using bosentan, with which we have far more experience.

    Clinicians rely upon the severity of liver fibrosis to segregate patients with well-compensated nonalcoholic fatty liver disease (NAFLD) into sub-populations at high versus low-risk for eventual liver-related morbidity and mortality. We compared hepatic gene expression profiles in high- and low-risk NAFLD patients to identify processes that distinguish the two groups and hence, might be novel biomarkers or treatment targets. Microarray analysis was used to characterize gene expression in percutaneous liver biopsies from low-risk, “mild” NAFLD patients (fibrosis stage 0–1, n=40) and high risk, “severe” NAFLD patients (fibrosis stage 3–4, n=32). Findings were validated in a second, independent cohort and confirmed by real time PCR and immunohistochemistry. As a group, patients at risk for bad NAFLD outcomes had significantly worse liver injury and more advanced fibrosis (severe NAFLD) than clinically-indistinguishable NAFLD patients with a good prognosis (mild NAFLD). A 64 gene profile reproducibly differentiated severe NAFLD from mild NAFLD, and a 20 gene subset within this profile correlated with NAFLD severity, independent of other factors known to influence NAFLD progression. Multiple genes involved with tissue repair/regeneration and certain metabolism-related genes were induced in severe NAFLD. Ingenuity Pathway Analysis and immunohistochemistry confirmed deregulation of metabolic and regenerative pathways in severe NAFLD, and revealed overlap among the gene expression patterns of severe NAFLD, cardiovascular disease, and cancer. Conclusion By demonstrating specific metabolic and repair pathways that are differentially activated in livers with severe NAFLD, gene profiling identified novel targets that can be exploited to improve diagnosis and treatment of patients who are at greatest risk for NAFLD-related morbidity and mortality.

    BACKGROUND Cardiac resynchronization therapy (CRT) reduces mortality, improves functional status, and induces reverse left ventricular remodeling in selected populations with heart failure (HF). The magnitude of reverse remodeling predicts survival with many HF medical therapies. However, there are few studies assessing the effect of remodeling on long-term survival with CRT. OBJECTIVE The purpose of this study was to assess the effect of CRT-induced reverse remodeling on long-term survival in patients with mildly symptomatic heart failure. METHODS The REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction trial was a multicenter, double-blind, randomized trial of CRT in patients with mild HF. Long-term follow-up of 5 years was preplanned. The present analysis was restricted to the 353 patients who were randomized to the CRT ON group with paired echocardiographic studies at baseline and 6 months post-implantation. The left ventricular end-systolic volume index (LVESVi) was measured in the core laboratory and was an independently powered end point of the REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction trial. RESULTS A 68% reduction in mortality was observed in patients with ≥15% decrease in LVESVi compared to the rest of the patients (P = .0004). Multivariable analysis showed that the change in LVESVi was a strong independent predictor (P = .0002), with a 14% reduction in mortality for every 10% decrease in LVESVi. Other remodeling parameters such as left ventricular enddiastolic volume index and ejection fraction had a similar association with mortality. CONCLUSION The change in left ventricular end-systolic volume after 6 months of CRT is a strong independent predictor of long-term survival in mild HF. PMID:25460860

    (1) Patients frequently complain of occasional bowel movement disorders, associated with abdominal pain or discomfort, but they are rarely due to an underlying organ involvement. Even when patients have recurrent symptoms, serious disorders are no more frequent in these patients than in the general population, unless other manifestations, anaemia, or an inflammatory syndrome is also present; (2) There is currently no way of radically modifying the natural course of recurrent irritable bowel syndrome; (3) The effects of antispasmodics on abdominal pain have been tested in about 20 randomised controlled trials. Pinaverium and peppermint essential oil have the best-documented efficacy and only moderate adverse effects. Antispasmodics with marked atropinic effects do not have a favourable risk-benefit balance; (4) Tricylic antidepressants seem to have only modest analgesic effects in this setting. In contrast, their adverse effects are frequent and they have somewhat negative risk-benefit balances. Nor has the efficacy of selective serotonin reuptake inhibitor antidepressants (SSRIs) been demonstrated; (5) Alosetron and tegaserod carry a risk of potentially life-threatening adverse effects and therefore have negative risk-benefit balances; (6) Seeds of plants such as psyllium and ispaghul, as well as raw apples and pears, have a limited impact on constipation and pain. Osmotic laxatives are effective on constipation. Symptomatic treatments for constipation can sometimes aggravate abdominal discomfort; (7) Loperamide has been poorly assessed in patients with recurrent irritable bowel syndrome with diarrhoea. It modestly slows bowel movement but does not relieve pain or abdominal discomfort; (8) Dietary measures have not been tested in comparative trials. Some patients are convinced that certain foods provoke a recurrence of irritable bowel syndrome, but restrictive diets carry a risk of nutritional deficiencies; (9) Various techniques intended to control emotional and

    Treatment of acute stroke is time-dependent, with the best outcomes resulting from the earliest interventions. However, for patients with acute ischemic stroke due to a high-grade stenosis of the internal carotid artery, despite maximal medical treatment, an effective intervention to improve their neurologic symptoms and clinical outcome has not yet been established. There are two major concerns: first, cerebral revascularization in the acute stage remains challenging because of the possibility that hemorrhagic infarction or hyperperfusion syndrome will occur after revascularization; second, alarms about carotid artery stenting in patients with acute symptoms are related to the fact that, while with carotid endarterectomy the plaque is completely removed, after stenting it is only remodelled and its stabilization is essential to avoid embolic events during the procedure and in the post-operative period. Although level 1 evidence seems clearly in favor of carotid endarterectomy in symptomatic patients, carotid stenting has been proposed as a possible alternative in selected cases if the procedure is performed in high-volume center with documented low perioperative stroke and death rates. This review summarizes indications and results for carotid artery stenting in recently symptomatic patients. PMID:23296417

    Purpose: We investigated clinical and treatment-related factors as predictors of symptomatic pericardial effusion in esophageal cancer patients after concurrent chemoradiation therapy. Methods and Materials: We reviewed 214 consecutive primary esophageal cancer patients treated with concurrent chemoradiation therapy between 2001 and 2010 in our institute. Pericardial effusion was detected on follow-up computed tomography. Symptomatic effusion was defined as effusion ≥grade 3 according to Common Terminology Criteria for Adverse Events v4.0 criteria. Percent volume irradiated with 5 to 65 Gy (V5-V65) and mean dose to the pericardium were evaluated employing dose-volume histograms. To evaluate dosimetry for patients treated with two-dimensional planning in the earlier period (2001-2005), computed tomography data at diagnosis were transferred to a treatment planning system to reconstruct three-dimensional plans without modification. Optimal dosimetric thresholds for symptomatic pericardial effusion were calculated by receiver operating characteristic curves. Associating clinical and treatment-related risk factors for symptomatic pericardial effusion were detected by univariate and multivariate analyses. Results: The median follow-up was 29 (range, 6-121) months for eligible 167 patients. Symptomatic pericardial effusion was observed in 14 (8.4%) patients. Dosimetric analyses revealed average values of V30 to V45 for the pericardium and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those with asymptomatic pericardial effusion (P<.05). Pericardial V5 to V55 and mean pericardial doses were significantly higher in patients with symptomatic pericardial effusion than in those without pericardial effusion (P<.001). Mean pericardial doses of 36.5 Gy and V45 of 58% were selected as optimal cutoff values for predicting symptomatic pericardial effusion. Multivariate analysis identified mean pericardial dose as the

    Background Optimal treatment for patients with symptomatic intraluminal carotid thrombus (ICT) remains poorly defined. Methods We performed a retrospective chart review of patients presenting to our institution between 2001 and 2011 with symptomatic ICT. Results Twenty-four patients (16 males, 8 females) with ICT presented with ischemic stroke (n=18) or TIA (n=6). All were treated initially with anticoagulation ± antiplatelet drugs. Eight of these patients had no or mild carotid stenosis on initial angiography and were treated with medical management alone. The remaining 16 patients had moderate or severe carotid stenosis on initial angiography. Of these, 10 underwent delayed revascularization (endarterectomy, n=8; angioplasty and stenting, n=2), 2 refused revascularization, and 4 were treated with medical therapy alone. One patient had multiple TIAs despite medical therapy and eventually underwent CEA; the remaining 23 patients had no TIAs. No patient suffered ischemic or hemorrhagic stroke while on anticoagulation, during the perioperative period or in long-term follow up; one patient died of an unrelated condition (mean follow-up = 16.4 months). Conclusion Our results suggest that initial anticoagulation of symptomatic ICT results in a low rate of recurrent ischemic events and that carotid revascularization, if indicated, can be safely performed in a delayed manner.

    Background Venous thromboembolism (VTE) prophylaxis remains underutilized among hospitalized patients. We designed and carried out a large multicenter randomized controlled trial to test the hypothesis that an alert from a hospital staff member to the Attending Physician will reduce the rate of symptomatic VTE among high-risk patients not receiving prophylaxis. Methods and Results We enrolled patients using a validated point score system to detect hospitalized patients at high risk for symptomatic VTE who were not receiving prophylaxis. 2,493 patients (82% on Medical Services) from 25 study sites were randomized to the intervention group (n=1,238), in which the responsible physician was alerted by another hospital staff member, versus the control group (n=1,255), in which no alert was issued. The primary end point was symptomatic, objectively confirmed VTE within 90 days. Patients whose physicians were alerted were more than twice as likely to receive VTE prophylaxis as controls (46.0% versus 20.6%, p<0.0001). The symptomatic VTE rate was lower in the intervention group (2.7% versus 3.4%; hazard ratio, 0.79; 95% confidence interval, 0.50 to 1.25), but the difference did not achieve statistical significance. The rate of major bleeding at 30 days in the alert group was similar to the control group (2.1% versus 2.3%, p=0.68). Conclusions A strategy of direct staff member to physician notification increases prophylaxis utilization and leads toward reducing the rate of symptomatic VTE in hospitalized patients. However, VTE prophylaxis continues to be underutilized even after physician notification, especially among Medical Service patients. PMID:19364975

    Intracranial atherosclerotic disease (ICAD) is likely the most common cause of stroke worldwide and remains highly morbid even with highly monitored medical therapy. Recent results of the SAMMPRIS trial, which randomized patients to stenting plus aggressive medical management versus aggressive medical management alone have shown that additional treatment of intracranial atherosclerotic lesions with the Wingspan stent is inferior to aggressive medical management alone. In light of these results, there has been renewed interest in angioplasty alone to treat symptomatic ICAD. This article will briefly review the natural history of ICAD and discuss the possible future for endovascular treatment of ICAD with primary intracranial angioplasty in appropriately selected patients.

    The aim of this study was to evaluate the incidence of secondary symptomatic vertebral compression fractures (VCFs) in patients previously treated by percutaneous vertebroplasty (VTP). Three hundred sixteen patients with 486 treated VCFs were included in the study according to the inclusion criteria. Patients were kept in regular follow-up using a standardized questionairre before, 1 day, 7 days, 6 months, and 1 year after, and, further on, on a yearly basis after VTP. The incidence of secondary symptomatic VCF was calculated, and anatomical distribution with respect to previous fractures characterized. Mean follow-up was 8 months (6-56 months) after VTP. Fifty-two of 316 (16.4 %) patients (45 female, 7 male) returned for treatment of 69 secondary VCFs adjacent to (35/69; 51%) or distant from (34/69; 49%) previously treated levels. Adjacent secondary VCF occurred significantly more often compared to distant secondary VCF. Of the total 69 secondary VCFs, 35 of 69 occurred below and 27 of 69 above pretreated VCFs. Of the 65 sandwich levels generated, in 7 of 65 (11%) secondary VCFs were observed. Secondary VCF below pretreated VCF occurred significantly earlier in time compared to VCF above and compared to sandwich body fractures. No major complication occurred during initial or follow-up intervention. We conclude that secondary VCFs do occur in individuals after VTP but the rate found in our study remains below the level expected from epidemiologic studies. Adjacent fractures occur more often and follow the cluster distribution of VCF as expected from the natural history of the underlying osteoporosis. No increased rate of secondary VCF after VTP was observed in this retrospective analysis. In accordance with the pertinent literature, short-term and also midterm clinical results are encouraging and provide further support for the usefulness and the low complication rate of this procedure as an adjunct to the spectrum of pain management in patients with severe

    Alzheimer disease (AD) is the most common cause of dementia in the elderly. Clinicopathological studies support the presence of a long preclinical phase of the disease, with the initial deposition of AD pathology estimated to begin approximately 10–15 years prior to the onset of clinical symptoms. The hallmark clinical phenotype of AD is a gradual and progressive decline in two or more cognitive domains, most commonly involving episodic memory and executive functions, that is sufficient to cause social or occupational impairment. Current diagnostic criteria can accurately identify AD in the majority of cases. As disease-modifying therapies are being developed, there is growing interest in the identification of individuals in the earliest symptomatic, as well as presymptomatic, stages of disease, because it is in this population that such therapies may have the greatest chance of success. The use of informant-based methods to establish cognitive and functional decline of an individual from previously attained levels of performance best allows for the identification of individuals in the very mildest stages of cognitive impairment.

    The resurgence of tuberculosis (TB) has coincided with deteriorating access to care for high-risk populations. We sought to determine what perceived access barriers delayed symptomatic TB patients from obtaining care. In order to do this, we conducted a survey in Los Angeles County, California, using a consecutive sample of patients with active TB as confirmed by the county TB control authority. The measures used in the study were a self-reported delay in seeking care of more than 60 d from symptom onset, a period sufficient to cause skin-test conversion in exposed contacts, and self-reported access barriers. The county TB registry provided supplementary clinical data. We found that one in five of the 248 symptomatic respondents (response rate: 60%) delayed obtaining care for > 60 d (mean = 74 d, SD = 216 d). During the delay, patients exposed an average of eight contacts. As compared with the rest of the sample, delay was more common in those who were unemployed (25% versus 14%), concerned about cost (27% versus 14%), anticipated prolonged waiting-room time (26% versus 14%), believed they could treat themselves (31% versus 14%), anticipated difficulty in getting an appointment (28% versus 16%), were uncertain about where to get care (33% versus 16%), and feared immigration authorities (47% versus 18%) (p < 0.05). Logistic regression revealed that uncertainty about where to get care, unemployment, and belief in the efficacy of self-treatment independently predicted delay > 60 d. Illness severity as measured by chest radiography, sputum smears, and symptoms had little impact on delay. We conclude that because access variables such as lack of employment and knowledge about where to obtain care were more closely associated with clinically significant delay than was severity of illness, these results raise concerns about the equity of access to care among TB patients. The results suggest that improving the availability of services for high-risk groups may substantially

    Lumbar spondylolysis, a stress fracture of the pars interarticularis, is prevalent in adolescent athletes. Recent advances in diagnostic tools and techniques enable early diagnosis before these fractures progress to complete fractures through the pars. However, because patients often consult family physicians for primary care of low back pain and these physicians may not have access to diagnostic modalities such as magnetic resonance imaging (MRI) and computed tomography, stress fractures can be missed. This study surveyed the prevalence of symptomatic spondylolysis in pediatric patients who consulted an orthopedic clinic for primary care and investigated whether such acute stress fractures may be overlooked without MRI. The prospective study investigated 264 patients who were younger than 19 years and had low back pain. Of the 153 patients (58.0%) with low back pain persisting for longer than 2 weeks, 136 who agreed to undergo MRI were included in the study. This group included 11 elementary school students, 71 junior high school students, and 54 high school students. The overall prevalence of lumbar spondylolysis was 39.7% (54 of 136) and was 9.3% in elementary school students (5 of 11, 45.5%), 59.3% in junior high school students (32 of 71, 45.1%), and 31.5% in high school students (17 of 54, 31.5%). All 54 patients with spondylolysis had a history of athletic activity. Primary care physicians should recognize that approximately 40% of pediatric patients presenting with low back pain persisting for longer than 2 weeks may have spondylolysis and should consider MRI in those with a history of athletic activity. Because the spine is immature in this age group, almost half of affected elementary school and junior high school students may have lumbar spondylolysis. [Orthopedics. 2016; 39(3):e434-e437.].

    PubMed

    2016-03-01

    Multicentric Castleman's disease is a rare lymphoproliferative disorder characterised by disseminated lymphadenopathy. Symptoms and outcomes differ widely from one patient to another. The median survival time is about 2.5 years. There is no consensus on treatment. Siltuximab, a monoclonal antibody that antagonises interleukin-6, has been authorised in the European Union for patients with multicentric Castleman's disease who are not infected with HIV or HHV-8. In a randomised, double-blind trial in 79 patients, most of whom had mild or moderate symptoms, the estimated one-year survival rate was 100% in the siltuximab group versus 92% in the placebo group after a median follow-up of 60 weeks. However, half of the patients in the placebo group received siltuximab after disease progression. Symptoms disappeared for at least 18 weeks in one-quarter of patients in the siltuximab group versus none of those in the placebo group; the median symptom-free period in the siltuximab group was about 16 months. The known adverse effects of siltuximab are related to its immunosuppressive effect. They include frequent infections, neutropenia and thrombocytopenia. Reactions can occur during the infusion, and mouth sores have been reported. Other adverse events that appear to be more frequent with siltuximab include cutaneous disorders, oedema, renal and cardiac disorders, and peripheral neuropathy. Cases of gastrointestinal perforation have been reported in trials in other clinical settings. Siltuximab can mask the signs and symptoms of acute inflammation, in particular by suppressing fever and acute-phase markers such as C-reactive protein. Interleukin-6 is a cytochrome P450 inhibitor. Siltuximab activates its isoenzymes and can thus reduce the effectiveness of the numerous drugs that are substrates of this enzyme system. This risk of interactions is likely to persist up to several weeks after siltuximab withdrawal, because of its long plasma elimination half-life (about 16 days

    Background Symptomatic leg length inequality accounts for 8.7% of total hip replacement related claims made against the UK National Health Service Litigation authority. It has not been established whether symptomatic leg length inequality patients following total hip replacement have abnormal hip kinetics during gait. Methods Hip kinetics in 15 unilateral total hip replacement patients with symptomatic leg length inequality during gait was determined through multibody dynamics and compared to 15 native hip healthy controls and 15 ‘successful’ asymptomatic unilateral total hip replacement patients. Finding More significant differences from normal were found in symptomatic leg length inequality patients than in asymptomatic total hip replacement patients. The leg length inequality patients had altered functions defined by lower gait velocity, reduced stride length, reduced ground reaction force, decreased hip range of motion, reduced hip moment and less dynamic hip force with a 24% lower heel-strike peak, 66% higher mid-stance trough and 37% lower toe-off peak. Greater asymmetry in hip contact force was also observed in leg length inequality patients. Interpretation These gait adaptions may affect the function of the implant and other healthy joints in symptomatic leg length inequality patients. This study provides important information for the musculoskeletal function and rehabilitation of symptomatic leg length inequality patients. PMID:25900447

    Prospective memory (PM) refers to the ability to remember to perform intended actions in the future. Although PM deficits are a prominent impairment in schizophrenia, little is still known about the nature of PM in symptomatically remitted patients with schizophrenia. To address this issue, event-related brain potentials (ERPs) were recorded from 20 symptomatically remitted patients with schizophrenia and 20 healthy controls during an event-based PM paradigm. Behavioral results showed that symptomatically remitted patients with schizophrenia performed poorly on the PM task compared with healthy controls. On the neural level, the N300, a component of the ERPs related to PM cue detection, was reliable across these two groups, suggesting a degree of functional recovery of processes supporting cue detection in patients with symptomatically remitted schizophrenia. By contrast, the amplitude of the prospective positivity, a component of the ERPs related to PM intention retrieval, was significantly attenuated in symptomatically remitted schizophrenia patients relative to healthy controls. Furthermore, a significant positive correlation between the amplitude of the prospective positivity and accuracy on the PM task was found in those patients, indicating that patients’ poor performance on this task may result from the failure to recover PM cue-induced intention from memory. These results provide evidence for the existence of altered PM processing in patients with symptomatically remitted schizophrenia, which is characterized by a selective deficit in retrospective component (intention retrieval) of PM. Therefore, these findings shed new light on the neurophysiological processes underlying PM in schizophrenia patients during clinical remission. PMID:26483650

    BACKGROUND--Autonomic neuropathy provides a mechanism for the absence of symptoms in silent myocardial ischaemia, but characterisation of the type of neuropathy is lacking. AIM--To characterise and compare autonomic nerve function in patients with silent and symptomatic myocardial ischaemia. METHODS AND RESULTS--The Valsalva manoeuvre, heart rate variation (HRV) in response to deep breathing and standing, lower body negative pressure, isometric handgrip, and the cold pressor test were performed by patients with silent (n = 25) and symptomatic (n = 25) ambulatory ischaemia and by controls (n = 21). No difference in parasympathetic efferent function between patients with silent and symptomatic ischaemia was recorded, but both had significantly less HRV in response to standing than the controls (p < 0.005 for silent and p < 0.01 for symptomatic). Patients with silent ischaemia showed an increased propensity for peripheral vasodilatation compared with symptomatic patients (p < 0.02) and controls (p < 0.04). Impaired sympathetic function was found in patients with pure silent ischaemia (n = 4) compared with the remaining patients with silent ischaemia whose pain pathways were presumed to be intact. CONCLUSIONS--Patients with silent ischaemia and pain pathways presumed to be intact have an enhanced peripheral vasodilator response, and if this applied to the coronary vasculature it could provide a mechanism for limiting ischaemia to below the pain threshold. Patients with pure silent ischaemia have evidence of sympathetic autonomic dysfunction. Images PMID:8297687

    Background/Aims We investigated writing abilities in patients with the amnestic type of mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD). To examine the earliest changes in writing function, we used writing tests for both words and sentences with different types of Japanese characters (Hiragana, Katakana, and Kanji). Methods A total of 25 aMCI patients, 38 AD patients, and 22 healthy controls performed writing to dictation for Kana and Kanji words, copied Kanji words, and wrote in response to a picture story task. Analysis of variance was used to test the subject group effects on the scores in the above writing tasks. Results For the written Kanji words, the mild AD group performed worse than the aMCI group and the controls, but there was no difference between the aMCI group and the controls. For the picture story writing task, the mild AD and aMCI groups performed worse than the controls, but the difference between the AD and the aMCI groups was not significant. Conclusions The mild AD group showed defects in writing Kanji characters, and the aMCI group showed impairments in narrative writing. Our study suggests that narrative writing, which demands complex integration of multiple cognitive functions, can be used to detect the subtle writing deficits in aMCI patients. PMID:26483830

    Metal sensitivity (MS) reactions to implant metals represent a rare but well-documented complication following total joint arthroplasty (TJA). Although 20-25% of post-TJA patients develop MS, only a few highly susceptible patients (< 1%) exhibit symptoms. Whether surgeons should perform screening for MS is currently a matter of debate. The present study investigated the clinical importance of screening for patients predisposed to symptomatic MS, and the specific metals causing symptomatic MS following total knee arthroplasty (TKA). Between 2000 and 2002, a total of 108 primary TKAs were performed on 92 patients. Preoperatively, all patients underwent modified lymphocyte stimulation test (mLST) to Ni, Co, Cr, and Fe. Of the 92 patients, 24 (26%) displayed positive preoperative responses to at least one metal. Five patients displayed implant metal-related eczema and were all mLST-positive preoperatively, suggesting that screening for symptomatic MS is clinically useful. Two of these underwent revision TKA and thereafter, eczema healed and mLST results changed from positive to negative. All mLST-positive patients were divided into three groups: Group I, patients with eczema; Group II, patients with clear history of MS; and Group III, patients neither eczema nor history of MS. When the type of sensitive metals were compared among the three groups, a significant association between presence of Cr-sensitivity and development of eczema (P < 0.05) was identified. No significant association was observed between other metals and development of eczema or history of MS. This indicates that Cr is a potential candidate metal for causing eczema in our TKA series, and Cr-sensitivity may offer a potential predictor for symptomatic MS. The present study indicates that the surgeons should undertake routine preoperative screening for MS, particularly to Cr. PMID:15369690

    It is essential that empathic and tender care assumes top priority in any physician's work despite or because of hightech medicine. Provision of care is not taught sufficiently in medical school and is not adequately trained during postgraduate formation mostly due to administrative overload. In addition, financial incentives are poorly developped. However warm patient care adds important personal value to any patient contact for the physician and protects--in the right dose--efficiently against a burnout syndrome. Some practical hints help the practising to regain some of this professional quality despite a highly rationalized health care system. PMID:16613285

    Background Recent evidence suggests that less than one-quarter of patients with symptomatic nosocomial Clostridium difficile infections (CDI) are linked to other in-patients. However, this evidence was limited to one geographic area. We aimed to investigate the level of symptomatic CDI transmission in hospitals located across England from 2008 to 2012. Methods A generalized additive mixed-effects Poisson model was fitted to English hospital-surveillance data. After adjusting for seasonal fluctuations and between-hospital variation in reported CDI over time, possible clustering (transmission between symptomatic in-patients) of CDI cases was identified. We hypothesised that a temporal proximity would be reflected in the degree of correlation between in-hospital CDI cases per week. This correlation was modelled through a latent autoregressive structure of order 1 (AR(1)). Findings Forty-six hospitals (33 general, seven specialist, and six teaching hospitals) located in all English regions met our criteria. In total, 12,717 CDI cases were identified; seventy-five per cent of these occurred >48 hours after admission. There were slight increases in reports during winter months. We found a low, but statistically significant, correlation between successive weekly CDI case incidences (phi = 0.029, 95%CI: 0.009–0.049). This correlation was five times stronger in a subgroup analysis restricted to teaching hospitals (phi = 0.104, 95%CI: 0.048–0.159). Conclusions The results suggest that symptomatic patient-to-patient transmission has been a source of CDI-acquisition in English hospitals in recent years, and that this might be a more important transmission route in teaching hospitals. Nonetheless, the weak correlation indicates that, in line with recent evidence, symptomatic cases might not be the primary source of nosocomial CDI in England. PMID:24932484

    Objectives: The objective of this study was to identify the location and magnitude of difference in acetabular rim morphology between the symptomatic and asymptomatic acetabula in a cohort of patients with symptomatic unilateral pincer-type FAI. Methods: After IRB approval, computed tomography (CT) scans of 43 patients (22 males, 21 females) diagnosed with unilateral pincer-type FAI were obtained. CT images of both hips were imported in DICOM format and segmented into 3-dimensional (3D) hemi-pelvises using 3D reconstruction software (Mimics, Materialise, Leuven, Belgium). The point-cloud data of the asymptomatic hemi-pelvis was mirrored onto the symptomatic side. Protrusion of the symptomatic side was recorded as a positive value and appeared as red on the color map (Figure 1). Data was collected in 3° intervals and analyzed by quadrant using the clock face method; reflecting the 12-3, 3-6, 6-9, and 9-12 o’clock positions. Results: The symptomatic acetabular rim was on average 0.39 ± 0.36 mm thicker than the corresponding location on the asymptomatic rim. When the acetabular clock face was broken up into quadrants, reflecting the 12-3, 3-6, 6-9, and 9-12 o’clock positions, the 12-3 o’clock position demonstrated the greatest difference between symptomatic and asymptomatic sides (Table 1). The 12-3 o’clock quadrant demonstrated significantly greater difference between symptomatic and asymptomatic sides (0.53±0.22 mm) as compared to the 3-6 o’clock position (0.39±0.27 mm; p=0.006), the 6-9 o’clock position (0.34±0.05 mm; p<0.001), and the 9-12 o’clock position (0.33±0.03; p<0.001). There was no correlation between gender and magnitude of difference at any location. Conclusion: Small changes in acetabular rim morphology, on the order of 0.5 mm or less can be the difference between symptomatic pincer-type FAI and the asymptomatic state. Knowledge of the healthy, unaffected side in unilateral FAI may provide a better template for rim recession rather

    Introduction The association between malignancy and venous thromboembolic disease (VTE) is well established. The independent impact of VTE, both symptomatic and incidental, on survival in patients with prostate cancer is not known. We conducted a retrospective cohort study to evaluate the effect of VTE of survival in prostate cancer. Methods Data regarding clinical characteristics, treatment and outcomes of 453 consecutive prostate cancer patients were collected. Fisher exact (categorical variables) and t-test (continuous variables) were utilized to test associations with VTE and mortality. Survival was estimated using the Kaplan Meier method. A Cox regression model was used to model the mortality hazard ratio (HR). Results At diagnosis, 358 (83%) patients had early stage disease, 43 (10%) had locally advanced disease and 32 (7%) had metastatic disease. During the follow up period, 122 (27%) patients died and 41 (9%) developed VTE (33 deep vein thrombosis, 5 pulmonary embolism, and 3 patients with both DVT and PE). Twenty-five VTE events were symptomatic and 16 were incidentally diagnosed on CT scans obtained for other reasons. VTE was associated with increased mortality [HR 6.89 (4.29–11.08), p<0.001] in a multivariable analysis adjusted for cancer stage, performance status, treatments and co-morbidities. There was no difference in survival between patients who had symptomatic and incidental VTE. Conclusion Venous thromboembolic disease, both symptomatic and incidental, is a predictor of poor survival in patients with prostate cancer, especially those with advanced disease. Further studies are needed to evaluate the benefit of prophylactic and therapeutic anticoagulation in this population. PMID:25126949

    Filarial parasites infect an estimated 140 million people worldwide. Wuchereria bancrofti, Onchocerca volvulus, Loa loa and Mansonella perstans are responsible for most filarial infections in sub-Saharan Africa. We describe the prevalence and the clinical characteristics of filariasis in symptomatic patients in Goundi Sanitary district:167 patients were enrolled (99 men, 68 women). M. perstans microfilariae were isolated in peripheral blood in 164 cases, while Loa loa and Wuchereria bancrofti filariasis were diagnosed in only six and three cases, respectively. The most frequent filariasis observed in our study were due to M. perstans and L. loa, while the few cases of W. bancrofti filariasis seem to have been acquired abroad. No cases of O. volvulus were observed. Microfilarial burden was not related to symptoms, but a correlation between eosinophilia and pruritus was evident. No relationship was observed between eosinophils and symptoms. The prevalence observed in symptomatic patients could reflect the real prevalence of filariasis. PMID:17716512

    Purpose To evaluate the clinical outcomes of symptomatic bone lesions in patients with multiple myeloma (MM) who received local radiotherapy (LRT). Materials and Methods Fifty-one patients with 87 symptomatic bone lesions treated via LRT were analyzed. LRT was delivered at a median total dose of 21 Gy (range, 12 to 40 Gy) in a median of 7 fractions (range, 4 to 20 fractions). The clinical outcomes of LRT and the factors affecting treatment response were assessed. Results After a median follow-up time of 66.7 weeks, symptom relief was achieved for 85 of 87 lesions (97.7%). The median time to symptom relief was 7 days from the start of LRT (range, 1 to 67 days). The duration of in-field failure-free survival ranged from 1.1 to 450.9 weeks (median, 66.7 weeks). The radiation dose or use of previous and concurrent chemotherapy was not significantly associated with in-field failure for LRT (p = 0.354, 0.758, and 0.758, respectively). Conclusion Symptomatic bone lesions in patients with MM can be successfully treated with LRT. A higher radiation dose or the use of concurrent chemotherapy may not influence the in-field disease control. A relatively low radiation dose could achieve remission of symptoms in patients with MM.

    OBJECTIVE: To assess the role of caffeine restriction in the management of patients with symptomatic idiopathic ventricular premature beats. DESIGN: A randomised, double blind, 6 week intervention trial incorporating dietary caffeine restriction, caffeinated coffee, and decaffeinated coffee. SETTING: Cardiac outpatient clinic. PATIENTS: 13 patients with symptomatic frequent idiopathic ventricular premature beats. MAIN OUTCOME MEASURES: Weekly measures of serum caffeine concentration, coffee consumption, visual analogue score of palpitations, and 24 hour ventricular premature beat frequency. RESULTS: The interventions achieved significant alterations in serum caffeine concentrations (P < 0.001) which correlated with coffee consumption (r = 0.70; P < 0.001). Visual analogue palpitation scores showed a small, but significant correlation with ventricular premature beat frequencies (r = 0.34; P = 0.003). However, there were no significant changes in palpitation scores or ventricular premature beat frequencies during the intervention weeks and no significant correlations were found between these variables and serum caffeine concentrations. CONCLUSIONS: Caffeine restriction has no role in the management of patients referred with symptomatic idiopathic ventricular premature beats. PMID:8983684

    Background Moyamoya disease is characterized by progressive narrowing of the internal carotid artery (ICA). Symptomatic patients typically undergo cerebrovascular intervention via extracranial–intracranial (EC–IC) bypass, most often with the use of the superficial temporal artery. This case of Moyamoya disease is of particular interest as the patient presented with a unilateral atherosclerotic external carotid artery (ECA) stenosis after EC–IC bypass that eliminated the benefit of his original surgery, resulting in a symptomatic presentation. Clinical presentation A 53-year-old man presenting with Moyamoya disease and known left ICA occlusion had received a bilateral encephaloduroarteriosynangiosis (EDAS) bypass 10 years previously. He re-presented complaining of right-sided tingling, weakness, and numbness radiating up the arm. CT angiography indicated significant stenosis of the left ECA. ECA angioplasty and stenting with a distal protection device resulted in resolution of his symptoms. Conclusions This case illustrates that a patient presenting with Moyamoya disease and concurrent symptomatic ECA stenosis post-EDAS can be effectively and safely treated with ECA stenting.

    Between January 1988 and December 1990, 283 patients with symptomatic gall stones were referred for non-operative treatment. After ultrasound scanning including a functional assessment, 220 (78%) patients were found to be suitable for percutaneous cholecystolithotomy. Of these, 113 underwent the procedure including 10 in whom extracorporeal shock-wave lithotripsy or methyl tert-butyl ether therapy had failed. Forty four patients underwent extracorporeal shockwave lithotripsy, methyl tert-butyl ether therapy or rotary lithotripsy, 46 chose laparoscopic cholecystectomy or minicholecystectomy and 27 declined treatment. Percutaneous cholecystolithotomy was successfully performed in 100 patients. Thirty four patients were a high operative risk and 14 presented with an acute complication of gall stone disease. Complications developed in 15 patients, all of whom were managed conservatively and most occurred during development of the technique. Outcome has been assessed clinically and by ultrasound scanning in 92 patients with a median follow up period of 14 months (six to 37 months). Seventy nine per cent were completely cured of their symptoms. Ninety three per cent of gall bladders were shown to be functioning and nine (9.8%) contained stones, although five of these are believed to have developed from residual fragments. Percutaneous cholecystolithotomy is a safe, non-operative treatment for symptomatic gall stones and enabled the patient to fully recover within two to three weeks; it has a definite role in the management of the elderly and high risk patient but its use for the treatment of other groups is likely to remain controversial.

    To explore the associated risk factors of symptomatic knee osteonecrosis (KON) in patients with systemic lupus erythematosus (SLE), we conducted a retrospective case-control study to compare the clinical and laboratory features between SLE patients with and without symptomatic KON matched by age and gender. Univariate and multivariate regression analyses were used to evaluate possible associated risk factors. Twenty (one male, nineteen females) out of 3941 lupus patients were identified as symptomatic KON, which was confirmed by magnetic resonance imaging. The mean age at KON onset was 34.4 (range 12-67) years, and the median course of lupus at KON onset was 72.5 (range 8-123) months. Univariate and multivariate analyses identified that the prevalence of cutaneous vasculitis (OR 5.23; 95 % CI 1.11-24.70), hyperfibrinogenemia (OR 4.75; 95 % CI 1.08-20.85), and elevated IgG levels (OR 6.05; 95 % CI 1.58-23.16) were statistically higher in KON group, and hydroxychloroquine (HCQ) usage was statistically lower in KON group (OR 0.27; 95 % CI 0.07-0.97). Glucocorticoid usage, in terms of maximal dose, duration of treatment, and the percentage of receiving methylprednisolone pulse therapy, did not show statistical difference between the two groups (p > 0.05). Symptomatic KON is a relatively rare complication of SLE. Cutaneous vasculitis, hyperfibrinogenemia, and elevated IgG levels are possible risk factors, whereas HCQ may provide a protective effect. Our results suggest that lupus activity as well as hypercoagulation status may play a role in the pathogenesis of KON in lupus. PMID:27230994

    Background Although the prevalence of full-thickness rotator cuff tears increases with age, many patients are asymptomatic and may not require surgical repair. The factors associated with pain and loss of function in patients with rotator cuff tears are not well defined. Purpose To determine which factors correlate with pain and loss of function in patients with symptomatic, atraumatic full-thickness rotator cuff tears who are enrolled in a structured physical therapy program. Study Design Cross-sectional study; Level of evidence, 3. Methods A multicenter group enrolled patients with symptomatic, atraumatic rotator cuff tears in a prospective, nonrandomized cohort study evaluating the effects of a structured physical therapy program. Time-zero patient data were reviewed to test which factors correlated with Western Ontario Rotator Cuff (WORC) index and American Shoulder and Elbow Surgeons (ASES) scores. Results A total of 389 patients were enrolled. Mean ASES score was 53.9; mean WORC score was 46.9. The following variables were associated with higher WORC and ASES scores: female sex (P = .001), education level (higher education, higher score; P <.001), active abduction (degrees; P = .021), and strength in forward elevation (P = .002) and abduction (P = .007). The following variables were associated with lower WORC and ASES scores: male sex (P = .001), atrophy of the supraspinatus (P = .04) and infraspinatus (P = .003), and presence of scapulothoracic dyskinesia (P < .001). Tear size was not a significant predictor (WORC) unless comparing isolated supraspinatus tears to supraspinatus, infraspinatus, and subscapularis tears (P = .004). Age, tear retraction, duration of symptoms, and humeral head migration were not statistically significant. Conclusion Nonsurgically modifiable factors, such as scapulothoracic dyskinesia, active abduction, and strength in forward elevation and abduction, were identified that could be addressed nonoperatively with therapy.

    Study Design Retrospective study. Objective Studies on age-related degenerative changes causing concurrent stenoses in the cervical, thoracic, and lumbar spines (triple stenosis) are rare in the literature. Our objectives were to determine: (1) the incidence of asymptomatic radiologic cervical and thoracic stenosis in elderly patients with symptomatic lumbar stenosis, (2) the incidence of concurrent radiologic spinal stenosis in the cervical and thoracic spines, and (3) the radiologic features of cervical stenosis that might predict concurrent thoracic stenosis. Methods Whole-spine T2 sagittal magnetic resonance images of patients older than 80 and diagnosed with lumbar spinal stenosis between January 2003 and January 2012 were evaluated retrospectively. We included patients with asymptomatic spondylotic cervical and thoracic stenosis. We measured the anteroposterior diameters of the vertebral body, bony spinal canal, and spinal cord, along with the Pavlov ratio and anterior or posterior epidural stenosis at the level of the disk for each cervical and thoracic level. We compared the radiologic parameters between the subgroups of cervical stenosis with and without thoracic stenosis. Results Among the 460 patients with lumbar stenosis, 110 (23.9%) had concurrent radiologic cervical stenosis and 112 (24.3%) had concurrent radiologic thoracic stenosis. Fifty-six patients (12.1%) had combined radiologic cervical and thoracic stenosis in addition to their symptomatic lumbar stenosis (triple stenosis). Anterior epidural stenosis at C7–T1 was associated with a high prevalence of thoracic stenosis. Conclusions It appears that asymptomatic radiologic cervical and thoracic stenosis is common in elderly patients with symptomatic lumbar stenosis. PMID:26430589

    Purpose To report the effectiveness of home-based pencil push-ups (HBPP) therapy for patients with symptomatic convergence insufficiency. Methods Data was collected prospectively on 16 patients who were diagnosed with convergence insufficiency beginning in January 2009. The study group was composed of ten male and six female patients. The duration of symptoms, refractive error, distant and near deviation angles, and near point of convergence (NPC) prior to and after 12 weeks of HBPP therapy were measured in all patients. Results The mean age of the patients was 19.3 years. The mean deviation angle of exophoria was 3 prism diopters (PD) at distant and 11.2 PD at near. The mean value of NPC prior to HBPP therapy was 36.3 cm; however, the near point of accommodation was within the normal range. After 12 weeks of HBPP therapy, the mean deviation angle of exophoria decreased to orthophoric at distant and 4 PD at near. The mean value of NPC decreased to 14.4 cm. Conclusions Twelve weeks of HBPP therapy appears to be an easy, cost-free and effective therapy for patients with symptomatic convergence insufficiency. PMID:21655044

    Purpose: To evaluate the safety and outcome of ovarian artery embolization (OAE) in patients with collateral supply to symptomatic uterine leiomyomata. Materials and Methods: Thirteen patients with relevant leiomyoma perfusion by way of enlarged ovarian arteries underwent additional OAE during the same (N = 10) or a second procedure (N = 3). Uterine artery embolization (UAE) was performed bilaterally in 10 and unilaterally in 2 patients with a single artery. One patient had no typical uterine arteries but bilaterally enlarged ovarian arteries, prompting bilateral OAE. OAE was accomplished with coil embolization in one and particle embolization in 12 patients. Symptoms before therapy and clinical outcome were assessed using a standardized questionnaire. Contrast-enhanced magnetic resonance (MR) imaging after embolization was available in 11 of 13 patients and was used to determine the percentage of fibroid infarction. Results: UAE and OAE were technically successful in all patients. One patient experienced prolonged irritation at the puncture site. Median clinical follow-up time was 16 months (range 4-37). Ten of 13 patients showed improvement or complete resolution of clinical symptoms. One patient reported only slight improvement of her symptoms. These women presented with regular menses. Two patients (15%), 47 and 48 years, both with unilateral OAE, reported permanent amenorrhea directly after embolization. Their symptoms completely resolved. Seven patients showed complete and 4 showed >90% fibroid infarction after embolization therapy. Conclusions: OAE is technically safe and effective in patients with ovarian artery collateral supply to symptomatic uterine leiomyomata. The risk of permanent amenorrhea observed in this study is similar to the reported incidence after UAE.

    Several recent studies have shown that patients presenting with mild acute ischemic stroke (mAIS) symptoms may have an unfavorable natural history. The presence of associated large vessel occlusion (LVO) may lead to even worse outcomes, but most mAIS patients are still excluded from acute stroke treatment (AST). A retrospective review of patients with acute ischemic stroke presenting to our institution between 2010 and 2014 was carried out. Inclusion criteria were mAIS (initial National Institutes of Health Stroke Scale [NIHSS] ⩽7) due to LVO, presenting within 6hours from onset. Demographics, treatments and short-term outcomes were analyzed. Favorable 30day outcome was defined as modified Rankin Scale (mRS) ⩽2. Out of 2636 patients, 62 patients (median age 63years, 33 (53.2%) males) met inclusion criteria. The anterior circulation was involved in 74.1%. Median admission NIHSS and pre-admission mRS were 4 and 0, respectively. Twenty-three patients (71.8%) received AST (intravenous tissue plasminogen activator: 14, intra-arterial therapy: 4, both: 5). Favorable outcomes were 4.5 times higher in treated (78.3%) versus untreated (53.8%) patients (odds ratio 4.5, 95% confidence interval 1.26-19.2; p=0.028). None of the treated patients had symptomatic intracranial hemorrhage. We demonstrate that a significant proportion of untreated mAIS patients with LVO have an unfavorable natural history. Our results suggest better outcomes in patients who receive early therapy rather than conservative management. The detection of LVO, even with mild clinical symptoms, may prompt rapid treatment considerations. PMID:27050916

    Experience with ciclesonide in patients with mild persistent bronchial asthma The study aimed to monitor the effectiveness and safety of the treatment with ciclesonide, administered once a day in a 160 microg dose, over a 3-month period, to a group of 100 patients diagnosed with mild persistent bronchial asthma with deterioration of problems after exercise. The results of the study prove significant positive effects of the preparation used. A significant improvement of FEV1 and PEF values was observed, as well as a statistically significant remission of both day and nocturnal symptoms of the disease, a significantly lower consumption of short-acting beta2-sympathomimetics, and an improvement of all evaluated data relating to the quality of life of the asthmatic patients. No adverse effects were registered. PMID:18257418

    Background Temporomandibular disorder (TMD) patients might present a number of concurrent clinical diagnoses that may be clustered according to their similarity. Profiling patients’ clinical presentations can be useful for better understanding the behavior of TMD and for providing appropriate treatment planning. The aim of this study was to simultaneously classify symptomatic patients diagnosed with a variety of subtypes of TMD into homogenous groups based on their clinical presentation and occurrence of comorbidities. Methods Clinical records of 357 consecutive TMD patients seeking treatment in a private specialized clinic were included in the study sample. Patients presenting multiple subtypes of TMD diagnosed simultaneously were categorized according to the AAOP criteria. Descriptive statistics and two-step cluster analysis were used to characterize the clinical presentation of these patients based on the primary and secondary clinical diagnoses. Results The most common diagnoses were localized masticatory muscle pain (n = 125) and disc displacement without reduction (n = 104). Comorbidity was identified in 288 patients. The automatic selection of an optimal number of clusters included 100% of cases, generating an initial 6-cluster solution and a final 4-cluster solution. The interpretation of within-group ranking of the importance of variables in the clustering solutions resulted in the following characterization of clusters: chronic facial pain (n = 36), acute muscle pain (n = 125), acute articular pain (n = 75) and chronic articular impairment (n = 121). Conclusion Subgroups of acute and chronic TMD patients seeking treatment can be identified using clustering methods to provide a better understanding of the clinical presentation of TMD when multiple diagnosis are present. Classifying patients into identifiable symptomatic profiles would help clinicians to estimate how common a disorder is within a population of TMD patients and

    BACKGROUND. The high transmissibility and widespread environmental contamination by Clostridium difficile suggests the possibility of airborne dissemination of spores. We measured airborne and environmental C. difficile adjacent to patients with symptomatic C. difficile infection (CDI). METHODS. We conducted air sampling adjacent to 63 patients with CDI for 180 h in total and for 101 h in control settings. Environmental samples were obtained from surfaces adjacent to the patient and from communal areas of the ward. C. difficile isolates were characterized by ribotyping and multilocus variable-number tandem-repeat analysis to determine relatedness. RESULTS. Of the first 50 patients examined (each for 1 h), only 12% had positive air samples, most frequently those with active symptoms of CDI (10%, vs 2% for those with no symptoms). We intensively sampled the air around 10 patients with CDI symptoms, each for 10 h over 2 days, as well as a total of 346 surface sites. C. difficile was isolated from the air in the majority of these cases (7 of 10 patients tested) and from the surfaces around 9 of the patients; 60% of patients had both air and surface environments that were positive for C. difficile. Molecular characterization confirmed an epidemiological link between airborne dispersal, environmental contamination, and CDI cases. CONCLUSIONS. Aerosolization of C. difficile occurs commonly but sporadically in patients with symptomatic CDI. This may explain the widespread dissemination of epidemic strains. Our results emphasize the importance of single-room isolation as soon as possible after the onset of diarrhea to limit the dissemination of C. difficile. PMID:20415567

    Objective The burden of Charcot Marie Tooth type 1A, the most common inherited peripheral neuropathy, including impact on patient quality of life is not well understood. This study aims to qualitatively describe the range of symptoms associated with Charcot Marie Tooth type 1A and impact on quality of life. Methods We performed qualitative interviews with 16 adult Charcot Marie Tooth type 1A patients. Each interview was analyzed using a qualitative framework technique to identify and index symptoms by theme. Results Sixteen patients provided 656 quotes. One hundred and forty-five symptoms of importance were identified representing 20 symptomatic themes. Symptoms associated with difficulty with mobility and ambulation, specific activity impairment, and emotional distress were the most frequently mentioned. Conclusions Multiple symptoms contribute to Charcot Marie Tooth type 1A disease burden, some previously under-recognized. Improved recognition of under-recognized symptoms will optimize patient care and quality of life. PMID:23965405

    Laparoscopic cholecystectomy (LC) has the advantages of early return to full daily activity, early return to work, and better cosmetic result, as well as quickly resolving pain. Yet how this information about the procedure influences a patient's attitude toward laparocopy is not known. In this study we analyzed the factors that play role in the decision-making process of patients who choose laparoscopic surgery, and we also evaluated patients' knowledge of laparoscopy and their expectations. A questionnaire was used in evaluating 98 patients suffering from symptomatic cholelithiasis scheduled for elective laparoscopic cholecystectomy between January 2001 and January 2002. Females constituted 81% of the study population. Most of the patients (56%) were housewives. While 45% of the patients had an educational status of primary school degree only, 14% had graduated from a university. Forty-three patients described their level of knowledge about laparoscopy as "low" (had only heard about laparoscopy). In 61% of the patients the surgeon was the sole decision maker about the type of the operation. Almost none of the patients had a preference for the time of discharge from the hospital after surgery, and only three of the actively working patients offered a time interval for return to work. From this study we concluded that most patients have inadequate information about laparoscopic surgery, that the type of operation is dictated mostly by the surgeon, and that early discharge and early return to work are not important for many patients.

    Ischemic preconditioning (IP) is a powerful cardioprotective cellular mechanism that has been related to the "warm-up phenomenon" or "walk-through" angina, and has been documented through the use of sequential exercise tests (ETs). It is known that several drugs, for example, cromokalim, pinacidil, adenosine, and nicorandil, can interfere with the cellular pathways of IP. The purpose of this article is to report the effect of the anti-ischemic agent trimetazidine (TMZ) on IP in symptomatic coronary artery disease (CAD) patients.We conducted a prospective study evaluating IP by the analysis of ischemic parameters in 2 sequential ETs. In phase I, without TMZ, patients underwent ET1 and ET2 with a 30-minute interval between them. In phase II, after 1 week of TMZ 35 mg twice daily, all patients underwent 2 consecutive ETs (ET3 and ET4). IP was considered present when the time to 1.0-mm segment ST on electrocardiogram deviation (T-1.0 mm) and rate pressure product (RPP) were greater in the second of 2 tests. The improvement in T-1.0 mm and RPP were compared in the 2 phases: without TMZ and after 1-week TMZ to assess the action of such drug in myocardial protective mechanisms. ETs were analyzed by 2 independent cardiologists.From 135 CAD patients screened, 96 met inclusion criteria and 62 completed the study protocol. Forty patients manifested IP by demonstrating an improvement in T-1.0 mm in ET2 compared with ET1, without the use of any drugs (phase I). In phase II, after 1-week TMZ, 26 patients (65%) did not show any incremental result in ischemic parameters in ET4 compared with ET3. Furthermore, of these patients, 8 (20%) had IP blockage.In this study, TMZ did not add any benefit to IP in patients with stable symptomatic CAD. PMID:26287407

    Studies with healthy elderly adults suggest that apathy, depression, and anxiety are more common among individuals with mild cognitive impairment (MCI). This study examined differences in mood/amotivational symptoms among patients with Parkinson's disease (PD) with and without MCI. Patients with PD (N=214) underwent neurocognitive evaluations including assessment of apathy (Apathy Scale), depression (Beck Depression Inventory-II), and trait anxiety (State-Trait Anxiety Inventory trait scale). Trait anxiety and depression were more severe in patients with PD with MCI. Delineation of MCI into amnestic and nonamnestic subtypes revealed greater depression, apathy, and anxiety among patients with PD with amnestic MCI relative to cognitively intact patients with PD. Patients with PD and MCI report greater mood symptoms compared to patients with PD who are cognitively intact. PMID:26792098

    Endocrine assessment was performed in 32 relapse-free southern Chinese patients 5-17 years following radiation therapy (RT) alone for early nasopharyngeal carcinoma (NPC). Initial screening was done using questionnaires emphasizing impaired sexual function and menstrual disturbance plus measurement of serum levels of thyroxine, free thyroxine index, thyrotropic hormone, prolactin, and additionally testosterone for males only. Those showing abnormalities were subjected to detailed pituitary function tests. Hypothalamic-pituitary dysfunction was found in 7 female patients and only 1 male patient. A delayed TSH response to thyrotropin releasing hormone suggesting a hypothalamic disorder was seen in 6 of the affected female patients, and hyperprolactinaemia in also 6. None of the patients had evidence of diabetes insipidus. Hypopituitarism became symptomatic 2-5 years after RT with a mean latent interval of 3.8 years. A practical protocol for regular endocrine assessment for NPC patients after RT has been proposed. Multiple linear regression analysis of the radiotherapeutic data from the 11 female patients indicates that the likelihood of late occurrence of symptomatic hypothalamic-pituitary dysfunction following RT is dependent on the TDF of the target dose to the nasopharyngeal region and the height of the upper margin of the opposed lateral facial fields above the diaphragma sellae (coefficient of multiple correlation = 0.9025). Except when the sphenoid sinus or the middle cranial fossa is involved, it is advisable to set the height of the upper margin of the lateral facial field at a level no higher than the diaphragma sellae. The hypothalamus and possibly the pituitary stalk as well may sustain permanent damage by doses of radiation within the conventional radiotherapeutic range for carcinomas.

    Alzheimerś disease (AD) is a progressive irreversible neurological brain disorder characterized by accumulation of amyloid-β, amyloid plaques, and neurofibrillary tangles. Inflammation and immune alterations have been linked to AD, suggesting that the peripheral immune system plays a role during the asymptomatic period of AD. NK cells participate in innate immune surveillance against intracellular pathogens and malignancy but their role in AD remains controversial. We have investigated changes in peripheral NK cell phenotypes and functions in amnestic mild cognitive impairment (aMCI, n = 10), patients with mild AD (mAD, n = 11), and healthy elderly controls (n = 10). Patients selected according to NINCDS-ADRDA criteria were classified using neuropsychological assessment tests. Phenotype analysis revealed differences in expression of CD16 (increased in mAD), NKG2A (decreased in aMCI), and TLR2 and TLR9 (both decreased in mAD). Functional assays revealed that NK cell killing activity and degranulation (CD107 expression) were unchanged in the three groups. In contrast, expression of the CD95 receptor was increased in aMCI and mAD. Granzyme B expression and cytokine production (TNFα, IFNγ) were increased in aMCI but not in mAD. CCL19- but not CCL21-dependent chemotaxis was decreased in aMCI and mAD, despite the fact that CCR7 expression was increased in aMCI. Our data suggest that the number of alterations observed in peripheral NK cells in aMCI represent an activation state compared to mAD patients and that may reflect an active immune response against a still to be defined aggression.

    The purpose of this study was to find the circulating microRNAs (miRNAs) co-related with the severity of coronary artery calcification (CAC), and testify whether the selected miRNAs could reflect the obstructive coronary artery disease in symptomatic patients. Patients with chest pain and moderated risk for coronary artery disease (CAD) were characterized with coronary artery calcium score (CACS) from cardiac computed tomography (CT). We analyzed plasma miRNA levels of clinical matched 11 CAC (CACS > 100) and 6 non-CAC (CACS = 0) subjects by microarray profile. Microarray analysis identified 34 differentially expressed miRNAs between CAC and non CAC groups. Eight miRNAs (miR-223, miR-3135b, miR-133a-3p, miR-2861, miR-134, miR-191-3p, miR-3679-5p, miR-1229 in CAC patients) were significantly increased in CAC plasma in an independent clinical matched cohort. Four miRNAs (miR-2861, 134, 1229 and 3135b) were correlated with the degree of CAC. Validation test in angiographic cohort showed that miR-134, miR-3135b and miR-2861 were significantly changed in patients with obstructive CAD . We identified three significantly upregulated circulating miRNAs (miR-134, miR-3135b and 2861) correlated with CAC while detected obstructive coronary disease in symptomatic patients. PMID:26537670

    Objectives The first non-vitamin K antagonist oral anticoagulant (NOAC) introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH) occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH. Methods We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014. Results ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years). Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset. Conclusion Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg) and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy. PMID:26171862

    Objectives Nodding syndrome (NS) is a poorly understood neurological disorder affecting thousands of children in Africa. In March 2012, we introduced a treatment intervention that aimed to provide symptomatic relief. This intervention included sodium valproate for seizures, management of behaviour and emotional difficulties, nutritional therapy and physical rehabilitation. We assessed the clinical and functional outcomes of this intervention after 12 months of implementation. Design This was a cross-sectional study of a cohort of patients with NS receiving the specified intervention. We abstracted preintervention features from records and compared these with the current clinical status. We performed similar assessments on a cohort of patients with other convulsive epilepsies (OCE) and compared the outcomes of the two groups. Participants Participants were patients with WHO-defined NS and patients with OCE attending the same centres. Outcome measures The primary outcome was the proportion of patients with seizure freedom (≥1 month without seizures). Secondary outcome measures included a reduction in seizure frequency, resolution of behaviour and emotional difficulties, and independence in basic self-care. Results Patients with NS had had a longer duration of symptoms (median 5 (IQR 3, 6) years) compared with those with OCE (4 (IQR 2, 6) years), p<0.001. The intervention resulted in marked improvements in both groups; compared to the preintervention state, 121/484 (25%) patients with NS achieved seizure freedom and there was a >70% reduction in seizure frequency; behaviour and emotional difficulties resolved in 194/327 (59%) patients; 193/484 (40%) patients had enrolled in school including 17.7% who had earlier withdrawn due to severe seizures, and over 80% had achieved independence in basic self-care. These improvements were, however, less than that in patients with OCE of whom 243/476 (51.1%) patients were seizure free and in whom the seizure frequency had

    Hypermagnesemia is an uncommon but a potentially serious clinical condition. Over-the-counter magnesium containing products are widely used as antacids or laxatives. Although generally well tolerated in patients with normal renal function, their unsupervised use in the elderly can result in severe symptomatic hypermagnesemia, especially in those patients with concomitant renal failure and bowel disorders. We report a case of severe symptomatic hypermagnesemia associated with over-the-counter laxatives in a 70-year-old male patient with renal failure and sigmoid volvulus, who was successfully treated with hemodialysis.

    Background: Delay in symptomatic presentation leading to advanced stage at diagnosis may contribute to poor cancer survival. To inform public health approaches to promoting early symptomatic presentation, we aimed to identify risk factors for delay in presentation across several cancers. Methods: We surveyed 2371 patients with 15 cancers about nature and duration of symptoms using a postal questionnaire. We calculated relative risks for delay in presentation (time from symptom onset to first presentation >3 months) by cancer, symptoms leading to diagnosis and reasons for putting off going to the doctor, controlling for age, sex and deprivation group. Results: Among 1999 cancer patients reporting symptoms, 21% delayed presentation for >3 months. Delay was associated with greater socioeconomic deprivation but not age or sex. Patients with prostate (44%) and rectal cancer (37%) were most likely to delay and patients with breast cancer least likely to delay (8%). Urinary difficulties, change of bowel habit, systemic symptoms (fatigue, weight loss and loss of appetite) and skin symptoms were all common and associated with delay. Overall, patients with bleeding symptoms were no more likely to delay presentation than patients who did not have bleeding symptoms. However, within the group of patients with bleeding symptoms, there were significant differences in risk of delay by source of bleeding: 35% of patients with rectal bleeding delayed presentation, but only 9% of patients with urinary bleeding. A lump was a common symptom but not associated with delay in presentation. Twenty-eight percent had not recognised their symptoms as serious and this was associated with a doubling in risk of delay. Embarrassment, worry about what the doctor might find, being too busy to go to the doctor and worry about wasting the doctor's time were also strong risk factors for delay, but were much less commonly reported (<6%). Interpretation: Approaches to promote early presentation should

    One hundred sixteen patients were evaluated to determine the ability of single photon emission computed tomographic (SPECT) thallium-201 exercise and redistribution imaging to detect silent ischemia secondary to restenosis in asymptomatic patients after single and multiple vessel percutaneous transluminal coronary angioplasty and the findings were compared with SPECT imaging detection of restenosis in symptomatic patients. The value of exercise electrocardiography (ECG) and the amount of ischemic myocardium in symptomatic and asymptomatic patients were determined. Forty-one patients were asymptomatic after angioplasty; 77% of these had chest pain before angioplasty. Seventy-five patients had chest pain after angioplasty; 99% of these had chest pain before angioplasty. Restenosis occurred in 61% of asymptomatic and 59% of symptomatic patients and in 46% of the vessels in both asymptomatic and symptomatic patients. Sensitivity, specificity and accuracy for detection of restenosis by SPECT in individual patients were 96%, 75% and 88% versus 91%, 77% and 85%, respectively, in the asymptomatic versus symptomatic groups (p = NS). Sensitivity, specificity and accuracy for restenosis detection in individual vessels were 90%, 89% and 89% versus 84%, 77% and 84%, respectively, in the asymptomatic and symptomatic groups (p = NS), with similar results for the three major arteries. Sensitivity and accuracy of exercise ECG were significantly less than those of SPECT imaging for the patients with silent (40% and 44%) and symptomatic (59% and 64%) ischemia (p less than 0.001). Restenosis of vessels in the patients with silent and symptomatic ischemia was associated with an equal amount and degree of severity of ischemic myocardium in the two groups.

    Background This is a qualitative study designed to examine neurosurgeons' and neuro-oncologists' perceptions of resampling surgery for glioblastoma multiforme electively, post-therapy or at asymptomatic relapse. Methods Twenty-six neurosurgeons, three radiation oncologists and one neuro-oncologist were selected using convenience sampling and interviewed. Participants were presented with hypothetical scenarios in which resampling surgery was offered within a clinical trial and another in which the surgery was offered on a routine basis. Results Over half of the participants were interested in doing this within a clinical trial. About a quarter of the participants would be willing to consider routine resampling surgery if: (1) a resection were done rather than a simple biopsy; (2) they could wait until the patient becomes symptomatic and (3) there was a preliminary in vitro study with existing tumour samples to be able to offer patients some trial drugs. The remaining quarter of participants was entirely against the trial. Participants also expressed concerns about resource allocation, financial barriers, possibilities of patient coercion and the fear of patients' inability to offer true informed consent. Conclusion Overall, if surgeons are convinced of the benefits of the trial from their information from scientists, and they feel that patients are providing truly informed consent, then the majority would be willing to consider performing the surgery. Many surgeons would still feel uncomfortable with the procedure unless they are able to offer the patient some benefit from the procedure such that the risk to benefit ratio is balanced.

    An emerging clinical priority for the treatment of Alzheimer’s disease (AD) is the implementation of therapies at the earliest stages of disease onset. All AD patients pass through an intermediary stage of the disorder known as Mild Cognitive Impairment (MCI), but not all patients with MCI develop AD. By applying computer based signal processing and pattern recognition techniques to the electroencephalogram (EEG), we were able to classify AD patients versus controls with an accuracy rate of greater than 80%. We were also able to categorize MCI patients into two subgroups: those with EEG Beta power profiles resembling AD patients and those more like controls. We then used this brain-based classification to make predictions regarding those MCI patients most likely to progress to AD versus those who would not. Our classification algorithm correctly predicted the clinical status of 4 out of 6 MCI patients returning for 2 year clinical follow-up. While preliminary in nature, our results suggest that automated pattern recognition techniques applied to the EEG may be a useful clinical tool not only for classification of AD patients versus controls, but also for identifying those MCI patients most likely to progress to AD.

    Abstract Background: Clarithromycin is often a component of combination therapies for Helicobacter pylori eradication; however, increases in resistance rates have decreased the success of the treatment. Objective: This study was designed to determine the prevalence of H pylori infection in symptomatic patients and to detect clarithromycin resistance rates using melting curve analysis. Methods: Patients scheduled for upper endoscopy at the Endoscopy Unit of the Department of Gastroenterology, Duzce University, Medical Faculty Hospital, Konuralp/Duzce, Turkey, were assessed for enrollment in the study. Two pairs of gastric biopsy specimens (antrum and corpus) were obtained from each study patient. Histopathologic examination, rapid urease test, culture, and polymerase chain reaction (PCR) of the specimens were used to identify H pylori infection. Clarithromycin resistance was detected using melting curve analysis. Results: Seventy-five patients (41 women, 34 men; mean [SD]age, 42.6 [14.5] years [range, 17–70 years]) were included in the study. Using histopathology and rapid urease test, H pylori was detected in 40 (53.3%) of the 75 specimens. H pylori was detected using PCR in 40 (53.3%) specimens and by culture in 10 (13.3%) specimens. The specificity and sensitivity of PCR and culture were interpreted by comparing them with the results of histopathologic examination and urease tests. The specificity and sensitivity of PCR were 68.6% and 72.5%, respectively, and the specificity and sensitivity of culture were 97.1% and 22.5%, respectively. Of the 40 isolates, 21 (52.5%) were susceptible to clarithromycin, 12 (30.0%) were resistant, and a mixed susceptibility pattern was detected in 7 (17.5%) specimens. H pylori isolates from 19 (79.2%) of the 24 patients who had formerly used clarithromycin showed clarithromycin resistance. Conclusions: The prevalence of H pylori infection was 53.3% for the symptomatic patients in this study, and 47.5% of the isolates showed

    Greater trochanteric pain syndrome (GTPS) is a common complaint. Recently, it has become well recognized that tendinopathy and tears of the gluteus medius (GM) are a cause of recalcitrant GTPS. Nevertheless, the clinical syndrome associated with GM tears is not fully characterized. We characterize the clinical history, findings on physical examination, imaging and intraoperative findings associated with symptomatic GM tears. Forty-five patients (47 hips) who underwent GM repair for the diagnosis of tear were evaluated. Pain was estimated on the visual analog scale (VAS) and hip-specific scores were administered to assess functional status. The imaging modalities were reviewed and intra operative findings were recorded. The average patient age was 54 years (17–76), 93% were females. Symptom onset was commonly insidious (75%) and the average time to diagnosis was 28 months (2–240). The most common pain location was the lateral hip (75%). The average pre-surgery VAS and modified Harris Hip Score were 6.65 (0–10) and 55.5 (12–90), respectively. All patients had pathological findings on magnetic resonance angiogram (MRA) ranging from tendinosis to complete tears of the GM tendon. There was a discrepancy between MRA interpretation by a radiologist and findings during surgery. Hip abductor tears are an under-recognized cause of hip pain and hip symptomatology. In this study, we further characterize the clinical presentation of this entity. The data we present here may facilitate early diagnosis, early orthopedic care and avoid unnecessary prolonged patient sufferings. PMID:27011854

    Patients with mild cognitive impairment (MCI) are by definition still autonomous in daily life and therefore make their own decisions, for example, concerning their own or their partners' health care. Health care information typically contains complex mathematical constructs like proportions, probabilities, and survival rates. The purpose of this study was to investigate whether patients with MCI have difficulties with understanding health numeracy questions and to explore the impact of declining cognitive functions. The performance of 25 patients with MCI in a health numeracy questionnaire was compared with the performance of a control sample including 164 healthy older adults, matched in age and educational level. Participants were asked to convert percentages, assess different probabilities, or understand the dosage of a short patient information leaflet. Additionally, neuropsychological background tests were administered. Patients with MCI answered fewer items correctly than controls in the health numeracy questionnaire. A correlation analysis showed statistically significant associations between performance in the health numeracy task and mental arithmetic, executive functions (psychomotor speed, conceptualization), and global cognitive status, respectively. Patients with MCI show problems in understanding numerical information concerning health care. Since patients with MCI are confronted with several health care decisions, special attention has to be paid to presenting information in an easily understandable way, to make additional sources of information available, and to provide adequate support.

    The diagnosis of cancer is a complex, multi-step process. In this paper, we highlight factors involved in missed opportunities to diagnose cancer more promptly in symptomatic patients and discuss responsible mechanisms and potential strategies to shorten intervals from presentation to diagnosis. Missed opportunities are instances in which post-hoc judgement indicates that alternative decisions or actions could have led to more timely diagnosis. They can occur in any of the three phases of the diagnostic process (initial diagnostic assessment; diagnostic test performance and interpretation; and diagnostic follow-up and coordination) and can involve patient, doctor/care team, and health-care system factors, often in combination. In this perspective article, we consider epidemiological 'signals' suggestive of missed opportunities and draw on evidence from retrospective case reviews of cancer patient cohorts to summarise factors that contribute to missed opportunities. Multi-disciplinary research targeting such factors is important to shorten diagnostic intervals post presentation. Insights from the fields of organisational and cognitive psychology, human factors science and informatics can be extremely valuable in this emerging research agenda. We provide a conceptual foundation for the development of future interventions to minimise the occurrence of missed opportunities in cancer diagnosis, enriching current approaches that chiefly focus on clinical decision support or on widening access to investigations.

    Myeloma cells thrive in an environment of sustained inflammation, which impacts the development and evolution of the disease, as well as drug resistance. We evaluated the impact of genetic polymorphisms in the Toll-like receptor 4 (TLR4) pathway, which have been implicated in different inflammatory responses in the outcomes of patients with symptomatic multiple myeloma (MM) who have received contemporary therapies. We found that the presence of single nucleotide polymorphisms (SNPs) in both the TLR4 and toll/interleukin-1 receptor (TIR)-associated protein (TIRAP) genes was associated with lower response to primary therapy mainly for patients who received immunomodulatory drugs but not in patients treated with bortezomib-based therapies. Furthermore, TIRAP SNP was associated with a significantly shorter progression-free survival and overall survival, independently of other prognostic factors, such as age, transplant, International Staging System stage, lactate dehydrogenase and cytogenetics. This is the first study to demonstrate the effect of SNPs in TLR4/TIRAP in MM. Our data indicate that genetic variability in the immune system may be associated with different responses to antimyeloma therapies and may be a critical component affecting the natural history of the disease, providing the basis for further investigation of the role of these pathways in myeloma.

    Since radiographic findings on oral cholecystography (OCG) have implications for the eligibility for nonsurgical therapy of elderly patients, we investigated the OCGs of 448 symptomatic gallstone patients (109 male, 339 female; mean age, 49.8 +/- 14 (range, 21-88)). Opacification of the gallbladder was found in 323 cases (72.1%). Calcifications of gallstones were found in 85 opacified gallbladders (26.3%). Solitary and multiple stones were calcified in 35.3% and 18.2%, respectively (P < 0.0005). When divided into two groups (< or = 40 years and > 40 years), there was a significant increase in calcifications (P < 0.02) and a non-significant increase in opacification with increasing age. It is concluded that age is a determinant for calcification of gallstones and not opacification of the gallbladder. Since multiple stones are proportionately observed more in clinical studies than in epidemiologic studies, it is suggested that multiplicity of stones predisposes to biliary complaints. That solitary stones are more likely to be calcified than multiple stones, adds to the hypothesis that solitary and multiple stones have a different pathogenesis. Elderly patients, in whom non-surgical therapy is most likely to be indicated and cost-effective, are less likely to be suitable for this form of treatment, since age is a determinant for stone calcification.

    We designed a retrospective cohort study to assess sex-related differences in clinical manifestations, incidence, and outcomes of patients with symptomatic acute aortic dissection (AAD). We collected clinical data from 2010 to 2015 of 400 patients with AAD. Patients' clinical characteristics, treatment, and outcomes were analyzed as a function of sex. Among 400 patients with AAD, the ratio of men to women was 3.18:1; the incidence of atherosclerosis was higher in women (P = 0.02). Dysphoria (P = 0.01), focal neurological deficits (P = 0.04), and pulse deficits (P = 0.03) were more frequent in men. Imaging findings revealed that pleural effusion (P < 0.01), celiac trunk involvement (P < 0.01), and superior mesenteric artery involvement (P = 0.02) were more frequent in men. Dissection-related pneumonia (P = 0.02), pulmonary atelectasis (P = 0.01), aortic intramural hematoma (P < 0.01), ischemic electrocardiographic changes (P = 0.03), and in-hospital complications such as myocardial ischemia (P = 0.03), hypoxemia (P < 0.01), cardiac tamponade (P = 0.01) occurred more frequently in women. Women with type A dissection had higher in-hospital mortality than men (P < 0.01). The presentation of AAD varies with a patient's sex. Women with AAD had clinical features different from men as follows: higher age of onset, more frequent inpatient complications, and higher in-hospital mortality. These findings may lead to a better understanding of aortic dissection in women that will improve their outcomes. PMID:26986151

    Abstract The aim of this study was to determine the clinical outcomes of long-term anticoagulation therapy in patients with symptomatic spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) and to evaluate whether conservative treatment with anticoagulation therapy is a safe and effective treatment modality for these patients. In this single center, observational cohort study, data from a prospectively recruiting symptomatic SIDSMA registry, including demographics, risk factors of interest, clinical characteristics and outcomes, and initial and follow-up computed tomography angiography (CTA) findings, were analyzed retrospectively. During an 8-year period, a total of 52 consecutive patients who underwent conservative treatment with the use of long-term anticoagulation were included in this study. Clinical symptoms resolved within 11 days in all except 4 patients (7.7%); 3 received endovascular treatment for persistent symptoms and 1 received surgical repair. The mean duration of anticoagulation therapy was 9 (range: 3–60) months. A follow-up CTA showed complete remodeling in 20 (41.7%) patients, and the mean diameter and the incidence of false lumen thrombosis were also decreased significantly. There was no anticoagulation therapy-related mortality or morbidity except 2 (4.2%) minor bleeding complications, and no symptomatic recurrence or aggravation of the dissection occurred during the mean follow-up period of 47.5 (range: 10–97) months. The present study showed that long-term anticoagulation therapy could result in a high rate of complete remodeling during the natural course of symptomatic SIDSMA. Conservative treatment with long-term anticoagulation therapy could be an optimal treatment strategy for symptomatic SIDSMA. PMID:27100453

    Background: Early diagnosis of familial transthyretin (TTR) amyloid diseases remains challenging because of variable disease penetrance. Currently, patients must have an amyloid positive tissue biopsy to be eligible for disease-modifying therapies. Endomyocardial biopsies are typically amyloid positive when cardiomyopathy is suspected, but this disease manifestation is generally diagnosed late. Early diagnosis is often difficult because patients exhibit apparent symptoms of polyneuropathy, but have a negative amyloid biopsy. Thus, there is a pressing need for an additional early diagnostic strategy for TTR-aggregation-associated polyneuropathy and cardiomyopathy. Methods and Findings: Global peripheral blood cell mRNA expression profiles from 263 tafamidis-treated and untreated V30M Familiar Amyloid Neuropathy patients, asymptomatic V30M carriers, and healthy, age- and sex-matched controls without TTR mutations were used to differentiate symptomatic from asymptomatic patients. We demonstrate that blood cell gene expression patterns reveal sex-independent, as well as male- and female-specific inflammatory signatures in symptomatic FAP patients, but not in asymptomatic carriers. These signatures differentiated symptomatic patients from asymptomatic V30M carriers with >80% accuracy. There was a global downregulation of the eIF2 pathway and its associated genes in all symptomatic FAP patients. We also demonstrated that the molecular scores based on these signatures significantly trended toward normalized values in an independent cohort of 46 FAP patients after only 3 months of tafamidis treatment. Conclusions: This study identifies novel molecular signatures that differentiate symptomatic FAP patients from asymptomatic V30M carriers as well as affected males and females. We envision using this approach, initially in parallel with amyloid biopsies, to identify individuals who are asymptomatic gene carriers that may convert to FAP patients. Upon further validation

All the patients were found to have impaired bronchial patency; most (63.6%) patients had lung volume and capacity changes, almost half (45.5%) the patients had pulmonary gas exchange dysfunction. Impaired bronchial patency mainly appeared as decreased MEF50, MEF15, and FEV1/VC%; altered lung volumes and capacities manifested chiefly by increased RV and decreased VC; pulmonary gas exchange dysfunction showed up primarily as lowered PaO2. The magnitude of the observed functional changes was generally slight. MEF50, MEF75, FEV1/VC%, and VC dropped to 59-20 and 79-70% of the normal value, respectively. RV increased up to 142-196% of the normal value; PaO2 reduced up to 79-60% mm Hg. PMID:15478560

    OBJECTIVES The optimal management and treatment of pericardial effusion are still controversial. There is limited data related to the risk factors affecting survival in these patients. The aim of this study was to determine the risk factors affecting the survival rate of patients with symptomatic pericardial effusion who underwent surgical interventions. METHODS From 2004 to 2011, we retrospectively analysed 153 patients who underwent subxiphoid pericardial window as their surgical intervention to drain pericardial effusions at the National Research Institute of Tuberculosis and Lung diseases (NRITLD). To determine the effects of risk factors on survival rate, demographic data, clinical records, echocardiographic data, computed tomographic and cytopathological findings and also operative information of patients were recorded. Patients were followed annually until the last clinical follow-up (August 2011). To determine the prognostic factors affecting survival, both univariate analysis and multivariate Cox proportional hazards model were utilized. RESULTS There were 89 men and 64 women with a mean age of 50.3 ± 15.5 years. The most prevalent symptom was dyspnoea. Concurrent malignancies were present in 66 patients. Lungs were the most prevalent primary site for malignancy. The median duration of follow-up was 15 (range 1–85 months). Six-month, 1-year and 18-month survival rates were 85.6, 61.4 and 36.6%, respectively. In a multivariate analysis, positive history of lung cancer (hazard ratio [HR] 2.894, 95% confidence interval [CI] 1.362–6.147, P = 0.006) or other organ cancers (HR 2.315, 95% CI 1.009–50311, P = 0.048), presence of a mass in the computed tomography (HR 1.985, 95% CI 1.100–3.581, P = 0.023), and echocardiographic findings compatible with tamponade (HR 1.745, 95% CI 1.048–2.90 P = 0.032) were the three independent predictors of postoperative death.

    The aims of this study were to investigate concrete and abstract word definition ability (1) between patients with amnestic mild cognitive impairment (aMCI) and normal adults and (2) between the aMCI subtypes (i.e., amnestic single-domain MCI and amnestic multidomain MCI; asMCI and amMCI) and normal controls. The 68 patients with aMCI (29 asMCI and 39 amMCI) and 93 age- and education-matched normal adults performed word definition tasks composed of five concrete (e.g., train) and five abstract nouns (e.g., jealousy). Task performances were analyzed on total score, number of core meanings, and number of supplementary meanings. The results were as follows. First, the aMCI patients scored significantly poorer than the normal controls in only abstract word definition. Second, both subtypes of aMCI performed worse than the controls in only abstract word definition. In conclusion, a definition task of abstract rather than concrete concepts may provide richer information to show semantic impairment of aMCI. PMID:26347214

    OBJECTIVE To evaluate the efficacy and safety of actovegin in patients with diabetic polyneuropathy. RESEARCH DESIGN AND METHODS In this multicenter, randomized, double-blind trial, 567 patients with type 2 diabetes received 20 intravenous infusions of actovegin (2,000 mg/day) (n = 281) or placebo (n = 286) once daily followed by three tablets of actovegin (1,800 mg/day) or placebo three times daily for 140 days. Total symptom score (TSS) of the lower limbs and vibration perception threshold (VPT) were used as coprimary outcome measures, computed as the area under the curve (AUC) from repeated scores and divided by duration of exposure. Secondary end points included individual TSS symptoms, neuropathy impairment score of the lower limbs (NIS-LL), and quality of life (short form [SF]-36). RESULTS TSS was significantly improved during actovegin treatment compared with placebo, as assessed by AUC (-0.56 points [95% CI -0.85 to -0.27]; P = 0.0003), and from baseline to 160 days (-0.86 points [-1.22 to -0.50]; P < 0.0001). VPT (five sites per foot) decreased by 3% (95% CI 0-6; P = 0.084) with actovegin than placebo, as assessed by AUC, and by 5% (1-9; P = 0.017) after 160 days. NIS-LL sensory function, as assessed by AUC, was significantly improved with actovegin versus placebo (-0.25 [95% CI -0.46 to -0.04]; P = 0.021), as was the SF-36 mental health domain. There were no differences in the incidence of adverse events between the groups. CONCLUSIONS Sequential intravenous and oral actovegin treatment over 160 days improved neuropathic symptoms, VPT, sensory function, and quality of life in type 2 diabetic patients with symptomatic polyneuropathy.

    Purpose Umeclidinium/vilanterol (UMEC/VI) is a novel fixed dose combination of a long-acting muscarinic receptor antagonist (LAMA) and a long-acting beta 2 receptor antagonist (LABA) agent. This analysis evaluated the incremental cost-effectiveness ratio (ICER) of UMEC/VI compared with tiotropium (TIO), from the Spanish National Health System (NHS) perspective. Methods A previously published linked equations cohort model based on the epidemiological longitudinal study ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points) was used. Patients included were COPD patients with a post-bronchodilator forced expiratory volume in 1 second (FEV1) ≤70% and the presence of respiratory symptoms measured with the modified Medical Research Council dyspnea scale (modified Medical Research Council ≥2). Treatment effect, expressed as change in FEV1 from baseline, was estimated from a 24-week head-to-head phase III clinical trial comparing once-daily UMEC/VI with once-daily TIO and was assumed to last 52 weeks following treatment initiation (maximum duration of UMEC/VI clinical trials). Spanish utility values were derived from a published local observational study. Unitary health care costs (€2015) were obtained from local sources. A 3-year time horizon was selected, and 3% discount was applied to effects and costs. Results were expressed as cost/quality-adjusted life years (QALYs). Univariate and probabilistic sensitivity analysis (PSA) was performed. Results UMEC/VI produced additional 0.03 QALY and €590 vs TIO, leading to an ICER of €21,475/QALY. According to PSA, the probability of UMEC/VI being cost-effective was 80.3% at a willingness-to-pay of €30,000/QALY. Conclusion UMEC/VI could be considered as a cost-effective treatment alternative compared with TIO in symptomatic COPD patients from the Spanish NHS perspective. PMID:26848262

    Introduction: We explore relationships between selected lifestyle factors and recent (≤6 months) symptomatic urolithiasis (RSU). Methods: Surveys querying socio-demographic, medical history, physical activity, diet and smoking were administered to a convenience sample of stone clinic patients at a tertiary care hospital. Leisure time physical activity (LTPA) was assessed with the International Physical Activity Questionnaire (long form). Multivariate logistic regression was used to identify associations between risk factors and RSU. Results: Of the 163 participants, most were male (64%) and white (78%), with a mean (standard deviation) age of 56.3 (14.2) years. The mean body mass index (BMI) was 27.3 (5.4) kg/m2 and 57 (35%) patients reported RSU. No significant (p < 0.05) differences were observed between participants with and without RSU in age, sex, ethnicity, BMI, or diet. Of the cohort, 52 (35%) participants met physical activity guidelines for walking (29%), moderate (27%) or vigorous activity (29%). LTPA did not differ significantly by RSU status. Compared to those without RSU, participants with RSU had higher rates of smoking (7% vs. 21%, p = 0.02 and had 8.5 (95% confidence interval 2.2–32.2) times the odds of being current smokers after controlling for sex, diet, and LTPA. Conclusions: Physical inactivity and smoking are common among stone clinic patients, though LPTA was not associated with RSU. Study limitations include its small sample size, selection bias, and reliance on self-reported RSU (recall bias). In addition, participants may have already been following dietary recommendations to prevent urolithiasis recurrence. Nonetheless, current smoking was a potent predictor of RSU. When desired, smokers should be referred for smoking cessation. PMID:26316909

    Aims and Objectives: To investigate the prevalence and morphological features of Ponticulus Posticus (PP) in symptomatic and asymptomatic patients of Gulbarga population, to substantiate whether ponticulus posticus was the possible cause of chronic tension-type headaches and migraine. Material and Methods: Five hundred patients were investigated with digital lateral cephalograms for the presence and type of ponticulus posticus. All the patients in whom ponticulus posticus was present in either partial or complete form were further studied for symptoms like chronic tension type headache, orofacial pain or diagnosed migraine. Results: Among the sample of 500 cases, partial ponticulus posticus was found in 302 patients (60%) (Males 48% and Females 52%). Complete variant was found in 40 cases (8%) (Males 65% and females 35% both, who were in the age group of 16-45 years), with a mean age of 28 years and SD 27.76 ±10.74. In partial PP, 42 patients (14%) were found to be symptomatic. In complete form, 32 patients (78%) were found to be symptomatic. Symptoms were mainly in the form of migraine or chronic type of headache. Conclusion: According to our study, partial form of PP was found to be more prevalent as compared to complete form in Gulbarga population and complete form of ponticulus posticus can be considered as possible cause for chronic tension type headache, orofacial pain and migraine.

    Purpose. To evaluate the mid-term clinical results and patient satisfaction following uterine artery embolization (UAE) in women with symptomatic fibroids. Methods. Between August 1998 and December 2002, 135 patients had UAE for symptomatic uterine fibroids. All patients were asked to fill in a questionnaire. Questions were aimed at changes in bleeding, pain, and bulk-related symptoms. Symptoms after UAE were scored as disappeared, improved, unchanged or worsened. Adverse events were noted, such as vaginal dryness and discharge, menopausal complaints or fibroid expulsion. Patient satisfaction after UAE was assessed. Patient satisfaction of women embolized with polyvinyl alcohol (PVA) particles was compared with satisfaction of women embolized with calibrated microspheres. Results. The questionnaire was returned by 110 of 135 women (81%) at a median time interval of 14 months following UAE. In 10 women additional embolization or hysterectomy had been performed. Of the 110 responders, 86 (78%) were satisfied with the result of UAE. The proportion of satisfied women was higher in the group embolized with calibrated microspheres than in women embolized with PVA, although this difference was not statistically significant (p = 0.053). Conclusion. UAE in women with symptomatic uterine fibroids leads to improvement of symptoms and patient satisfaction is good in the vast majority after a median follow-up period of 14 months.

    Background and Purpose— Intracranial atherosclerosis is a major cause of ischemic stroke worldwide. Intracranial vessel wall imaging is an upcoming field of interest to assess intracranial atherosclerosis. In this study, we investigated total intracranial plaque burden in patients with symptomatic middle cerebral artery stenosis, assessed plaque morphological features, and compared features of symptomatic and asymptomatic lesions using a 3T vessel wall sequence. Methods— Nineteen consecutive Chinese patients with ischemic stroke and transient ischemic attack (mean age: 67 years; 7 females) with a middle cerebral artery stenosis were scanned at 3T magnetic resonance imaging; the protocol included a time-of-flight magnetic resonance angiography and the T1-weighted volumetric isotropically reconstructed turbo spin echo acquisition sequence before and after (83%) contrast administration. Chi-square tests were used to assess associations between different plaque features. Statistical significance was set at P<0.05. Results— Vessel wall lesions were identified in 18 patients (95%), totaling 57 lesions in 494 segments (12% of segments). Lesions were located primarily in the anterior circulation (82%). Eccentric lesions were associated with a focal thickening pattern and concentric lesions with a diffuse thickening pattern (P<0.001). When differentiating between asymptomatic and symptomatic lesions, an association (P<0.05) was found between eccentricity and asymptomatic lesions, but not for enhancement or a specific thickening pattern. Symptomatic lesions did not have any specific morphological features. Conclusions— Our results lead to a 2-fold conclusion: (1) The classification system of both thickening pattern and distribution of the lesion can be simplified by using distribution pattern only and (2) differentiation between symptomatic and asymptomatic atherosclerotic lesions was possible using intracranial vessel wall imaging.

    Conclusions Patients with symptomatic perforations of the nasal septum had a high prevalence of S. aureus in the nasal mucosa. Pulsed field gel electrophoresis (PFGE) analysis revealed a high genetic heterogeneity of S. aureus among both patients and controls. This indicates that presence of different strains of S. aureus can maintain a chronic inflammation in symptomatic nasal septal perforations. Objective The purpose of this study was to investigate the microbial flora around nasal septal perforations in patients having severe symptoms regarding bleeding, obstruction, and crustation associated with their perforation. Methods Twenty-five patients with untreated symptomatic nasal septal perforations were included. For culture, swabs around the perforations were collected. Bacteria were identified with standard laboratory techniques including a MALDI-TOF mass spectrometer. Epidemiological analysis was done using PFGE protocols. Bacteriological data were compared with data from a healthy control group. Results Staphylococcus aureus was present in the mucosa surrounding the nasal perforation significantly more often (p < 0.0001) in the patients (88%) compared to a control group (13%). Corynebacterium spp. and Propionibacterium spp. were significantly more frequently identified in the control group. The PFGE analysis of S. aureus strains revealed a high genetic heterogeneity and no specific S. aureus genotypes were associated with septal perforation. PMID:26852671

    Objective: To quantify the negative impact that major depressive disorder (MDD) has on quality of life, disability, and work, family, and overall psychosocial functioning. Available scales that assess these areas of impairment as they relate to patients with MDD are described. Data Sources: PubMed searches were conducted using the following terms: (MDD OR major depressive disorder) AND (absenteeism OR absente*); AND (quality of life OR QOL); AND (psychosocial function*); AND (presente* OR presenteeism); AND (health care cost* OR [health care] cost*); AND (health outcome*); AND (functional outcome*); AND (family life); AND (disabil* OR disability); AND (work function*); AND (unemployment OR unemploy*). The literature search was conducted in July 2008 and was restricted to English language articles. There were no limits set on the dates of the search. Study Selection: Two hundred twenty potential articles were identified. Among these studies, 48 presented primary data directly demonstrating the effect of MDD on quality of life, disability, and work, family, and overall psychosocial functioning. Data Extraction: Primary data were compiled from these studies and are summarily described. Available scales that assess quality of life, disability, and work, family, and overall psychosocial functioning are also described. Data Synthesis: MDD was found to be associated with significant disability and declines in functioning and quality of life. The Sheehan Disability Scale, the 36-item Short-Form Health Survey, and the Work Limitations Questionnaire were the most commonly used scales according to this review of the literature, but the majority of studies used direct and indirect disability measures, such as health care and other disability-related costs. Conclusions: In addition to assessing symptomatic outcomes, physicians should routinely assess their depressed patients on “real-world” outcomes. The development of a concise functional outcome measure specific to MDD is

    Background Little is known about whether the arteriovenous type haemodialysis access affects cardiac function and whether it is still advantageous to the uremic patient with symptomatic heart disease. Methods We conducted a retrospective comparative study. Patients with heart disease and end-stage renal disease that had a new chronic access created between January 2007 and December 2008 and met the inclusion criteria were assessed. The endpoint was major adverse event (MAE)-free survivals of arteriovenous access (AVA) and tunneled cuffed double-lumen central venous catheter (CVC) groups. Whether accesses worsened heart failure was also evaluated. Results There were 43 CVC patients and 60 AVA patients. The median follow-up time from access creation was 27.6 months (IQR 34.7, 10.9~45.6). Although CVC patients were older than AVA patients (median age 78.0, IQR 14.0 vs. 67.5, IQR 16.0, respectively, p = .009), they manifested non-inferior MAE-free survival (mean 17.1, 95% CI 10.3~24.0 vs. 12.9, 95% CI 8.5~17.4 months in CVC and AVA patients, respectively, p = .290). During follow-up, more patients in the AVA group than in the CVC group deteriorated in heart failure status (35 of 57 vs. 10 of 42, respectively, odds ratio 5.1, p < .001). Preoperative-postoperative pairwise comparison of echocardiographic scans revealed an increased number of abnormal findings in the AVA group (Z = 3.91, p < .001), but not in the CVC group. Conclusions In patients with both symptomatic heart disease and end stage renal disease (ESRD), CVC patients showed non-inferior MAE-free survival in comparison to those in the AVA group. AV type access could deteriorate heart failure. Accordingly, uremic patients with symptomatic heart disease are not ideal candidates for AV type access creation. PMID:26848850

    Von Hippel-Lindau disease is a rare genetic disorder which gives rise to a range of tumours including central nervous system haemangioblastomas. We report a case of caesarean section in a patient with symptomatic cerebellar haemangioblastomas associated with von Hippel-Lindau disease. An intracranial pressure monitor was inserted before surgery, which enabled intracranial pressure to be monitored throughout. The anaesthetic implications of von Hippel-Lindau disease are discussed and clinical options explored. PMID:25499015

    Symptom burden in myeloproliferative neoplasms (MPNs) is heterogeneous even among patients within the same MPN diagnosis. Using cluster analysis from prospectively gathered symptom burden data in 1470 international patients with essential thrombocythemia (ET), polycythemia vera (PV), or myelofibrosis (MF), we assessed for the presence of clusters and relationship to disease features and prognosis. In MF (4 clusters identified), clusters significantly differed by Dynamic International Prognostic Scoring System (DIPSS) risk (P < .001), leukopenia (P = .009), thrombocytopenia (P < .001), and spleen size (P = .02). Although an association existed between clusters and DIPSS risk, high symptom burden was noted in some low and intermediate-1–risk MF patients. In PV (5 clusters identified), total symptom score increased across clusters (P < .001), but clusters did not significantly differ by PV risk or the risk assessment variable of age. Among ET patients (5 clusters identified), clusters differed by gender (P = .04), anemia (P = .01), and prior hemorrhage (P = .047). Total symptom score increased across clusters (P < .001), but clusters did not significantly differ by International Prognostic Score for ET risk including the risk assessment variables. Significant symptom heterogeneity exists within each MPN subtype, sometimes independent of disease features or prognosis. PMID:24553173

    This study sought to determine the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine in patients with symptomatic and asymptomatic irreversible pulpitis in mandibular posterior teeth and if individual patient factors, pulpal disease characteristics, and previous medication are correlated to local anesthetic success. A second objective was to determine the specificity and sensibility of a cold test for prediction of anesthetic success prior to endodontic treatment. Seventy patients diagnosed with irreversible pulpitis in mandibular posterior teeth received 1.6 mL of 4% articaine with 1:100,000 epinephrine for an inferior alveolar nerve block (IANB) using a metal guide. The anesthetic solution was injected with a computer-preprogrammed delivery system for local anesthesia. Endodontic access was begun 15 minutes after solution deposition; later, patients rated their discomfort using the visual analog scale (VAS). The success rate for the IA NB using articaine was 64.2% in patients with symptomatic irreversible pulpitis and 86.9% in patients with asymptomatic irreversible pulpitis. Cold test prior to root canal treatment had a specificity and sensibility of 12.5% and 87.1%, respectively. The anesthetic efficacy of articaine in irreversible pulpitis is moderately acceptable, and anesthetic success increases when the patient has been premedicated with NSAIDs. The cold test appears to be a favorable indicator for predicting anesthetic success. PMID:22313992

    The aim of the study was to determine whether gait characteristics were associated with endothelial cell inflammation, oxidative stress, and apoptosis and with circulating biomarkers of inflammation and antioxidant capacity in older patients with symptomatic peripheral artery disease (PAD). Gait measurements of 231 symptomatic men and women with PAD were assessed during a 4-m walk test. Patients were further characterized on endothelial effects of circulating factors present in the sera using a cell culture-based bioassay on primary human arterial endothelial cells and on circulating inflammatory and vascular biomarkers. In a multivariate regression model for gait speed, the significant independent variables were age (p < 0.001), intercellular cell adhesion molecule-1 (ICAM-1) (p < 0.001), diabetes (p = 0.003), sex (p = 0.003), and history of cerebrovascular accidents (p = 0.021). In multivariate analyses for gait cadence, the significant independent predictors included high-sensitivity C-reactive protein (HsCRP) (p < 0.001), diabetes (p = 0.001), and hypertension (p = 0.001). In a multivariate regression model for gait stride length, the significant independent variables were HsCRP (p < 0.001), age (p < 0.001), ICAM-1 (p < 0.001), hypertension (p = 0.002), cellular reactive oxygen species production (p = 0.007), and sex (p = 0.008). Higher levels of circulating biomarkers of inflammation and endothelial cell oxidative stress were associated with slower gait speed, slower cadence, and shorter stride length in older symptomatic patients with PAD. Additionally, this profile of impaired gait was more evident in older patients, in women, and in those with diabetes, hypertension, and history of cerebrovascular accidents. PMID:27273077

    Abstract Little is known about injury of the arcuate fasciculus (AF) in patients with mild traumatic brain injury (TBI). We investigated injury of the AF in the dominant hemisphere in patients with mild TBI, using diffusion tensor tractography (DTT). We recruited 25 patients with injury of the left AF among 64 right-handed consecutive patients with mild TBI and 20 normal control subjects. DTTs of the left AF were reconstructed, and fractional anisotropy (FA), apparent diffusion coefficient (ADC), and fiber number of the AF were measured. Among 64 consecutive patients, 25 (39%) patients showed injury of the left AF. The patient group showed lower FA value and fiber number with higher ADC value than the control group (P < 0.05). On K-WAB evaluation, aphasia quotient and language quotient were 95.9 ± 4.1 (range 85–100) and 95.0 ± 5.4 (range 80–100), respectively. However, 23 (92.0%) of 25 patients complained of language-related symptoms after TBI; paraphasia in 12 (48.0%) patients, deficits of comprehension in 4 (16.0%) patients, deficits of speech production in 1 (4.0%) patient, and >2 language symptoms in 6 (24.0%) patients. We found that a significant number (39%) of patients with mild TBI had injury of the AF in the dominant hemisphere and these patients had mild language deficit. These results suggest that DTT could provide useful information in detecting injury of the AF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.

    Objectives Assessment of dental pain severity is very challenging in dentistry. Previous studies have suggested that elevated salivary alpha amylase may contribute to increased physical stresses. There is a close association between salivary alpha amylase and plasma norepinephrine under stressful physical conditions. The aim of this study was to evaluate the relationship between pain severity and salivary alpha amylase levels in patients with symptomatic irreversible pulpitis. Materials and Methods Thirty-six patients (20 females and 16 males) with severe tooth pain due to symptomatic irreversible pulpitis were selected. The visual analogue scale (VAS) score was used to assess the pain severity in each patient. Unstimulated whole saliva was collected, and the level of alpha amylase activity was assessed by the spectrophotometric method. Statistical analysis was performed using SPSS 13. Results The level of alpha amylase was significantly increased in the saliva in association with pain severity assessed by VAS. The salivary alpha amylase was also elevated with increased age and in males. Conclusions There was a significant correlation between the VAS pain scale and salivary alpha amylase level, which indicates this biomarker may be a good index for the objective assessment of pain intensity.

    Pain interferes with various activities, such as coughing, deep breathing, and ambulation, designed to promote recovery and prevent complications after surgery. Determining appropriate cutpoints for mild, moderate, and severe pain is important, because specific interventions may be based on this classification. The purpose of this research was to determine optimal cutpoints for postoperative patients based on their worst and average pain during hospitalization and after discharge to home, and whether the optimal cutpoints distinguished patients with mild, moderate, or severe pain regarding patient outcomes. This secondary analysis consisted of 192 postoperative patients aged ≥60 years. Multivariate analyses of variance were used to stratify the sample into mild, moderate, and severe pain groups using eight cutpoint models for worst and average pain in the last 24 hours. One-way analyses of variance were conducted to determine whether patients experiencing mild, moderate, or severe pain were different in outcome. Optimal cutpoints were similar to those previously reported, with the boundary between mild and moderate pain ranging from 3 to 4 and the boundary between moderate and severe pain ranging from 5 to 7. Worst pain cutpoints were most useful in distinguishing patients regarding fatigue, depression, pain's interference with function, and morphine equivalent administered in the previous 24 hours. A substantial proportion of patients experienced moderate to severe pain. The results suggest a narrow boundary between mild and severe pain that interferes with function. The findings indicate that clinicians should seek to aggressively manage postoperative pain ratings greater than 3. PMID:24882032

    Metastatic prostate cancer continues to kill approximately 30,000 men per year. Since 2010, five new therapeutic agents have been Food and Drug Administration (FDA) approved to treat metastatic castration-resistant prostate cancer (mCRPC). With the increasing number of therapies available to clinicians, the most effective sequence in which to implement these treatments remains unknown. The presence or absence of symptoms (i.e., bony pain, visceral crisis) is a key parameter that informs the decision-making process regarding therapy. Treatment algorithms based on: 1) asymptomatic/minimal symptoms, 2) moderate symptoms or chemotherapy ineligible or 3) symptomatic disease need to be developed. PMID:25865849

    Introduction Intra-aortic counterpulsation balloon pumps (IABPs) have been widely used to augment hemodynamics in critically ill patients with cardiogenic shock and have recently been proposed as a management strategy for subarachnoid hemorrhage (SAH) patients with neurogenic stress cardiomyopathy (NSC). Prior case series have described the use of IABP as a means to manage cardiogenic shock in this patient population; however, we sought to describe our experience with IABP as a means to wean vasopressor requirement while augmenting hemodynamics and maintaining pressures at goal. Methods Five patients were identified from a single center, prospective, observational cohort study that received an IABP for the management of ischemia related to cerebral vasospasm in the setting of NSC. We evaluated all cases for efficacy of IABP in reducing vasopressor requirement, and complications. Results Vasopressor requirements were reduced by a mean of 50% (range 25–65%) following IABPs placement within 24–48 h. There were no significant complications from IABPs. Out of the five patients, the outcome in three cases was favorable (mRS≤1). Two patients suffered delayed cerebral ischemia (DCI), one patient passed away due to severe sepsis, and one patient was left with severe disability. Only one patient required anticoagulation and that was for a preexisting deep venous thrombosis. Conclusion The use of IABPs may be beneficial as an adjunctive therapy in SAH patients with concomitant symptomatic vasospasm and NSC. PMID:27403221

    We aimed to identify the role of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein (MCP-1) as a serum biomarker of symptomatic carotid atherosclerotic plaque in North Indian population. Individuals with symptomatic carotid atherosclerotic plaque have high risk of ischemic stroke. Previous studies from western countries have shown an association between VEGF and MCP-1 levels and the incidence of ischemic stroke. In this study, venous blood from 110 human subjects was collected, 57 blood samples of which were obtained from patients with carotid plaques, 38 neurological controls without carotid plaques, and another 15 healthy controls who had no history of serious illness. Serum VEGF and MCP-1 levels were measured using commercially available enzyme-linked immunosorbent assay. We also correlated the data clinically and carried out risk factor analysis based on the detailed questionnaire obtained from each patient. For risk factor analysis, a total of 70 symptomatic carotid plaque cases and equal number of age and sex matched healthy controls were analyzed. We found that serum VEGF levels in carotid plaque patients did not show any significant change when compared to either of the controls. Similarly, there was no significant upregulation of MCP-1 in the serum of these patients. The risk factor analysis revealed that hypertension, diabetes, and physical inactivity were the main correlates of carotid atherosclerosis (p < 0.05). Prevalence of patients was higher residing in urban areas as compared to rural region. We also found that patients coming from mountain region were relatively less vulnerable to cerebral atherosclerosis as compared to the ones residing at non mountain region. On the contrary, smoking, obesity, dyslipidemia, alcohol consumption, and tobacco chewing were not observed as the determinants of carotid atherosclerosis risk in North India (p > 0.05). We conclude that the pathogenesis of carotid plaques may progress

    "Delayed or back up" antibiotic prescriptions and "symptomatic" treatment may help to reduce inappropriate antibiotic prescribing for Urinary Tract Infections (UTI) in the future. However, more research needs to be conducted in this area before these strategies can be readily promoted in practice. This study explores General Practitioner (GP) and patient attitudes and experiences regarding the use of delayed or back-up antibiotic and symptomatic treatment for UTI. Qualitative face to face interviews with General Practitioners (n = 7) from one urban and one rural practice and telephone interviews with UTI patients (n = 14) from a rural practice were undertaken. Interviews were analysed using framework analysis. GPs believe that antibiotics are necessary when treating UTI. There was little consensus amongst GPs regarding the role of delayed prescribing or symptomatic treatment for UTI. Delayed prescribing may be considered for patients with low grade symptoms and a negative dipstick test. Patients had limited experience of delayed prescribing for UTI. Half indicated they would be satisfied with a delayed prescription the other half would question it. A fear of missing a serious illness was a significant barrier to symptomatic treatment for both GP and patient. The findings of this research provide insight into antibiotic prescribing practices in general practice. It also highlights the need for further empirical research into the effectiveness of alternative treatment strategies such as symptomatic treatment of UTI before such strategies can be readily adopted in practice.

    Central venous stenosis is a well-described sequel to the placement of hemodialysis catheters in the central venous system. The presence of an ipsilateral arteriovenous fistula or graft often leads to severe venous dilatation, arm edema and recurrent infections. Vascular access thrombosis, compromised blood flow and inadequate dialysis delivery are dreaded complications that eventually render the access unusable. We report the case of a 58-year-old male hemodialysis patient who developed symptomatic central venous stenosis to illustrate the problem and review the pertinent literature. This patient developed severe enlargement of upper extremity veins due to central venous stenosis. The symptoms were refractory to multiple endovascular interventions and eventually necessitated ligation of his arteriovenous fistula. Central venous stenosis remains a pervasive problem despite advances in our understanding of its etiology and recognition of the enormity of its consequences. Due to the lack of effective therapeutic options, prevention is better than cure. PMID:24803921

    Objectives: Primary objective was to assess the prevalence of tuberculosis (TB) among household contacts of newly diagnosed sputum smear (SS) positive TB index cases. Secondary objectives were the evaluation of risk factors in household contacts for acquiring TB disease; and the evaluation of various characteristics of index cases which influence the transmission of disease to household contacts. Settings and Design: This exploratory cohort study included 521 household contacts of 133 newly diagnosed SS positive TB patients who were registered under the Revised National Tuberculosis Control Program at the Directly Observed Treatment-Short Course Centres of District Tuberculosis Centre, Kolhapur, Maharashtra from July 1, 2013 to February 28, 2014 (8 months). Subjects and Methods: Household contacts with symptoms suggestive to TB were subjected to SS examination of two samples for acid fast bacilli by Ziehl-Neelsen staining and for X-ray chest postero-anterior view. Presence of risk factors in symptomatic contacts was also recorded. Results: Eighteen contacts out of 521 (3.45%) had symptoms suggestive of TB. Of these, 6 contacts were diagnosed to have TB; 5 being sputum positive cases and one with X-ray suggestive of TB; giving a prevalence of 1.15 %. The study achieved a yield of 4.51% secondary cases. Conclusions: Household contact screening of newly diagnosed TB index cases provides modest yield of cases. Relatively fewer secondary symptomatic persons need to be investigated by this method for achieving additional yield proving it to be a practical and feasible approach. PMID:27051103

    Purpose: To present a series of cases of non-cirrhotic patients with symptomatic massive portal thrombosis treated by percutaneous techniques. All patients underwent a TIPS procedure in order to maintain the patency of the portal vein by facilitating the outflow. Methods: A total of six patients were treated for thrombosis of the main portal vein (6/6); the main right and left branches (3/6) and the splenic vein (5/6) and superior mesenteric vein (6/6). Two patients had a pancreatic malignancy; one patient with an orthotopic liver transplant had been surgically treated for a pancreatic carcinoma. Two patients had idiopathic thrombocytosis, and in the remaining patient no cause for the portal thrombosis was identified. During the initial procedure in each patient one or more approaches were tried: transhepatic (5/6), transileocolic (1/6), trans-splenic (1/6) or transjugular (1/6). In all cases the procedure was completed with a TIPS with either ultrasound guidance (3/6), 'gun-shot' technique (2/6) or fluoroscopic guidance (1/6).Results: No complications were observed during the procedures. One patient had a repeat episode of variceal bleeding at 30 months, one patient remained asymptomatic and was lost to follow-up at 24 months, two patients were successfully treated surgically (cephalic duodenopancreatectomy) and are alive at 4 and 36 months. One patient remains asymptomatic (without new episodes of abdominal pain) at 16 months of follow-up. One patient died because of tumor progression at 10 months. Conclusion: Percutaneous techniques for portal recanalization are an interesting alternative even in non-acute thrombosis. Once flow has been restored in the portal vein TIPS may be necessary to obtain an adequate outflow, hence facilitating and maintaining the portal flow.

    A high proportion of patients with stable angina remains symptomatic despite multiple treatment options. Di'ao Xinxuekang (XXK) capsule and Compound Danshen (CDS) tablet have been approved for treating angina pectoris for more than 20 years in China. We compare the anti-anginal effectiveness of XXK capsule and CDS tablet in patients with symptomatic chronic stable angina. A randomized, multicenter, double-blind, parallel-group, superiority trial was conducted in 4 study sites. 733 patients with symptomatic chronic stable angina were included in the full analysis set. The primary outcomes were the proportion of patients who were angina-free and the proportion of patients with normal electrocardiogram (ECG) recordings during 20 weeks treatment. Compared with CDS, XXK significantly increased the proportion of angina-free patients, but no significant difference was noted in the proportion of patients with normal ECG recordings. Weekly angina frequency and nitroglycerin use were significantly reduced with XXK versus CDS at week 20. Moreover, XXK also improved the quality of life of angina patients as measured by the SAQ score and Xueyu Zheng (a type of TCM syndrome) score. We demonstrate that XXK capsule is more effective for attenuating anginal symptoms and improving quality of life in patients with symptomatic chronic stable angina, compared with CDS tablet.

    Purpose To assess hemoglobin (Hb) outcomes and fatigue-related quality-of-life (QoL) (electronic assessment) in patients with solid tumors and symptomatic chemotherapy-induced anemia receiving cytotoxic chemotherapy and darbepoetin alfa (DA) or another erythropoiesis-stimulating agent according to European indication. Methods eAQUA was a Phase IV prospective observational study. The primary outcome (assessed in the primary analysis set [PAS]: patients receiving one or more DA dose who had baseline and week 9 assessments for Hb and QoL) was the proportion of patients receiving DA having both Hb increases ≥1 g/dL and improved QoL between baseline and week 9. Functional Assessment of Cancer Therapy-Fatigue (FACT-F) subscale scores were anchored to fatigue visual analog scale scores to determine the minimally important difference for improved QoL. Overall data/data over time are reported for the full analysis set (patients receiving one or more erythropoiesis-stimulating agent dose, n=1,158); week 9 data (ie, data relating to the primary and secondary outcomes) are reported for the PAS (n=510). Baseline and safety data are included for both the full analysis set and PAS. Results In the PAS, 69% of patients had stage IV disease and 96% were fatigued. The minimally important difference in FACT-F change score for QoL improvement was 3.5. From baseline to week 9, 32% (95% confidence interval: 28%–36%) of patients had both improved QoL and an Hb increase ≥1 g/dL; proportions were similar across the most common tumor types. At week 9, 49% and 58% of patients had improved QoL or Hb increases ≥1 g/dL, respectively; 70% and 76% had QoL or Hb improvements between baseline and study end, respectively. In the PAS, 16% of patients required transfusions and 32% required iron supplementation. Few patients (<1%) reported adverse drug reactions. Conclusion In this study, patients with solid tumors receiving DA per European indication for symptomatic chemotherapy-induced anemia

    Background and Purpose Imaging studies of traumatic brain injury demonstrate that the cerebellum is often affected. We aim to examine fractional anisotropy alteration in acute-phase mild traumatic brain injury patients in cerebellum-related white matter tracts. Materials and Methods This prospective study included 47 mild traumatic brain injury patients in the acute stage and 37 controls. MR imaging and neurocognitive tests were performed in patients within 7 days of injury. White matter integrity was examined by using diffusion tensor imaging. We used three approaches, tract-based spatial statistics, graphical-model-based multivariate analysis, and region-of-interest analysis, to detect altered cerebellar white matter integrity in mild traumatic brain injury patients. Results Results from three analysis methods were in accordance with each other, and suggested fractional anisotropy in the middle cerebellar peduncle and the pontine crossing tract was changed in the acute-phase mild traumatic brain injury patients, relative to controls (adjusted p-value < 0.05). Higher fractional anisotropy in the middle cerebellar peduncle was associated with worse performance in the fluid cognition composite (r = -0.289, p-value = 0.037). Conclusion Altered cerebellar fractional anisotropy in acute-phase mild traumatic brain injury patients is localized in specific regions and statistically associated with cognitive deficits detectable on neurocognitive testing.

    The symptomatic and concurrent depressions description need to resort to comorbidity and symptomatic co-occurrence concepts. Patients with depressive symptoms or in a major depressive episode may also be suffering from another nonmood psychiatric disorders as alcoholism, anxiety or eating disorders. Many general medical conditions which are link with depression are illustrated with the examples of cancer, coronary artery disease, endocrinologic diseases, dementia, stroke and chronic fatigue syndrome. When depression and another psychiatric or medical conditions occur together, it is important to provide to the practitioner guidelines for the decision to treat one of the two disorders. This paper contains an example of decisional algorithm. PMID:10337217

    Primary hyperparathyroidism(PHPT)is one of the common endocrine disorders, which results clinically in nephrolithiasis, osteoporosis, muscle weakness, cardiac and psychiatric abnormalities even in a mild or asymptomatic disease. Parathyroidectomy(PTX)is the only definitive treatment for PHPT, however, some patients with sporadic PHPT refuse surgery, are medically unfit, or have residual or recurrent disease inaccessible to further surgery. These patients may require intervention for management of symptomatic or moderate to severe hypercalcemia, bone loss or kidney calculi. PMID:27230840

    PURPOSE We aimed to investigate the safety and effectiveness of intracranial stenting in a population with severe (≥70%) symptomatic intracranial internal carotid artery (ICA) atherosclerotic stenosis. METHODS Fifty-eight patients with severe intracranial ICA atherosclerotic stenosis were prospectively enrolled. The baseline data, cerebral angiography, success rate, perioperative complications, clinical and imaging follow-up were prospectively analyzed. RESULTS All patients had successful intracranial stenting (100%), and the mean degree of stenosis was improved from 84.3%±7.5% to 23.5%±5.1% after the stent procedure. During the 30-day perioperative period, only one patient (1.7%) had ischemic stroke. Seven patients (12.1%) had headache and dysphoria. Thirty-six patients (62.1%) had clinical follow-up for 6–68 months after stenting. Five female patients (13.9%) had ipsilateral stroke including one death, but no disabling stroke, while three other patients (8.3%) had ipsilateral temporary ischemic attack (TIA). The recurrent stroke rate was higher in patients presenting with stroke (4/17, 23.5%) than in patients presenting with TIA (1/19, 5.3%), with no statistical significance (P = 0.33). Thirteen patients (22.4%) had imaging follow-up of 5–12 months following stenting, five of whom (38.5%) had in-stent restenosis. CONCLUSION Intracranial stenting for patients with intracranial ICA atherosclerotic stenosis has a low perioperative stroke rate and decent outcome on long-term follow-up, despite a relatively high in-stent restenosis rate.

    Introduction It is generally accepted that achieving complete anaesthesia with an Inferior Alveolar Nerve Block (IANB) in mandibular molars with symptomatic irreversible pulpitis is more challenging than for other teeth. Therefore, administration of Non-Steroidal Anti-Inflammatory Agents (NSAIDs) 1 hour prior to anaesthetic administration has been proposed as a means to increase the efficacy of the IANB in such patients. Aim The purpose of this prospective, double-blind, randomized clinical trial was to determine the effect of administration of oral premedication with ketorolac (KETO) and diclofenac potassium (DP) on the efficacy of IANB in patients with irreversible pulpitis. Materials and Methods One hundred and fifty patients with irreversible pulpitis were evaluated preoperatively for pain using Heft Parker visual analogue scale, after which they were randomly divided into three groups. The subjects received identical tablets of ketorolac, diclofenac pottasium or cellulose powder (placebo), 1 hour prior to administration of IANB with 2% lidocaine containing 1:200 000 epinephrine. Lip numbness as well as positive and negative responses to cold test were ascertained. Additionally pain score of each patient was recorded during cavity preparation and root canal instrumentation. Success was defined as the absence of pain or mild pain based on the visual analog scale readings. The data was analysed using One-Way Anova, Post-Hoc Tukey pair wise, Paired T – Test and chi-square test. Trial Registery Number is 4722/2015 for this clinical trial study. Results There were no significant differences with respect to age (p =0.098), gender (p = 0.801) and pre-VAS score (DP-KETO p=0.645, PLAC-KETO p =0.964, PLAC-DP p = 0.801) between the three groups. All patients had subjective lip anaesthesia with the IAN blocks. Patients of all the three groups reported a significant decrease in active pain after local anaesthesia (p< 0.05). The post injection VAS Score was least in group

    The prevalence of subclinical hypothyroidism (SH) is increasing, especially in obese people. The purpose of this study was to evaluate the difference in metabolic profiles between obese patients with mild increased thyrotropin (TSH) or with normal TSH. A total of 219 obese patients were recruited in this cross-sectional study. They were divided into 2 groups: obese patients with normal TSH (0.35-2.5 mU/l) and age-, and body mass index (BMI)-matched obese patients with higher-normal TSH (2.5-5.5 mU/l). We have named it compensatory hypothyroidism or mild thyroid hormone deficiency. Anthropometric data, glucose-lipid metabolism, markers of inflammation, body composition, and thyroid function parameters were measured. Results showed that: 1) The levels of fasting plasma glucose (FPG), high density lipoprotein cholesterol (HDL-C), and 25-hydroxyvitamin D levels were significantly lower in obese patients complicated by mild increased TSH than in obese patients with normal TSH (p<0.05). The fasting insulin (FINS) and C reactive protein (CRP) levels were significantly higher in obese patients complicated by mild increased TSH when compared to the obese patients with normal TSH (p<0.01). Jostel's TSH index (TSHI) and standard TSH index (sTSHI) were significantly higher in obesity with mild increased TSH when compared to obesity with normal TSH (both p<0.001). Thyroid's secretory capacity (GT) was significantly lower in obesity with mild increased TSH when compared to obesity with normal TSH (p<0.001). 2) In the obese patients complicated by mild increased TSH group, serum TSH was significantly positively correlated with ALT, AST and CP (p<0.05). In the obese patients with normal TSH group, serum TSH was significantly positively correlated with UA (p<0.05). In all subjects, serum TSH was significantly positively correlated with ALT, AST, FINS, CP, CRP, and UA (p<0.05), but negatively with DBP, FPG, and HDL-C (p<0.05). 3) There was significant difference of the

    Clinical trials of migraine therapy often require treatment when migraine pain intensity is moderate or severe, but many physicians find this practice artificial and patients often prefer to treat while pain is mild. This randomized, placebo-controlled study assessed the efficacy of zolmitriptan 2.5 mg in treating migraine while pain is mild, in patients who typically experience migraine attacks that are initially mild, but progress to moderate or severe. The intent-to-treat population comprised 280 patients (138 zolmitriptan; 148 placebo), with mean MIDAS grades of 29.6 (zolmitriptan) and 27.6 (placebo). Zolmitriptan 2.5 mg provided a significantly higher pain-free rate at 2 h (43.4% vs. 18.4% placebo; P < 0.0001). Significantly fewer zolmitriptan patients reported progression of headache pain to moderate or severe intensity 2 h postdose (53.7% vs. 70.4% placebo; P < 0.01), or required further medication within 24 h (46.4% vs. 71.1% placebo; P < 0.0001). The efficacy of zolmitriptan was more pronounced in patients treating during the first 15 min following pain onset. Adverse events were reported in 31.2% of patients treated with zolmitriptan (vs. 11.3% for placebo), and the incidence was lower in patients who treated early after attack onset. Zolmitriptan provides high efficacy when treating migraine while pain is mild, with the clinical benefits being more pronounced when treating early after migraine onset. PMID:15482352

    We sought to document the clinical performance of the 1st American Academy of Orthopaedic Surgeons (AAOS) guideline on the prevention of symptomatic pulmonary embolism (PE) after total knee arthroplasty (TKA) in Korean patients, in terms of the proportions of the each risk-stratified group, efficacy and safety. Consecutive 328 patients underwent TKA were preoperatively assessed for the risks of PE and bleeding and categorized into 4 groups: 1) standard risk, 2) high risk for PE, 3) high risk for bleeding, and 4) high risks both for PE and bleeding. One of three options was administered according to the groups (aspirin in group 1 or 4; enoxaparin and following aspirin in group 2; antithrombotic stocking in group 3). Incidences of symptomatic deep vein thrombosis (DVT) and PE, and major or minor bleeding complications were evaluated. Majority of the patients (86%) were assessed to be with standard risks both for PE and bleeding. No patient experienced symptomatic DVT or PE and major bleeding. Eleven percent of the patients discontinued chemoprophylaxis because of bleeding-related wound complication. In conclusion, the 1st AAOS guideline functions successfully in Korean patients undergoing TKA in terms of prevention of symptomatic DVT and PE while avoiding major bleeding complications.

    Polyhydramnios, megalencephaly, and symptomatic epilepsy syndrome (PMSE) is an ultra rare neurodevelopmental disorder characterized by severe, infantile-onset intractable epilepsy, neurocognitive delay, macrocephaly, and craniofacial dysmorphism. The molecular diagnosis of this condition has thus far only been made in 16 Old Order Mennonite patients carrying a homozygous 7 kb founder deletion of exons 9-13 of STRADA. We performed clinical whole exome sequencing (WES) on a 4-year-old Indian male with global developmental delay, history of failure to thrive, infantile spasms, repetitive behaviors, hypotonia, low muscle mass, marked joint laxity, and dysmorphic facial features including tall forehead, long face, arched eyebrows, small chin, wide mouth, and tented upper lip. A homozygous single nucleotide duplication, c.842dupA (p.D281fs), in exon 10 of STRADA was identified. Sanger sequencing confirmed the mutation in the individual and identified both parents as carriers. In light of the molecular discoveries, the patient's clinical phenotype was considered to be a good fit for PMSE. We identified for the first time a homozygous point mutation in STRADA causing PMSE. Additional bi-allelic mutations related to PMSE thus far have not been observed in Baylor ∼6,000 consecutive clinical WES cases, supporting the rarity of this disorder. Our findings may have treatment implications for the patient since previous studies have shown rapamycin as a potential therapeutic agent for the seizures and cognitive problems in PMSE patients. © 2016 Wiley Periodicals, Inc.

    Objectives To analyze the effect of metabolic syndrome (MetS) on prognosis of ischemic stroke secondary to intracranial stenosis in Chinese patients. Methods A prospective cohort of 701 patients with ischemic stroke, caused by intracranial stenosis, were followed at 3-month intervals for 1 year to monitor development of recurrent stroke or death. Imaging was performed using magnetic resonance angiography. MetS was defined using International Diabetes Federation (IDF) criteria. Results MetS was identified in 26.0% of the cohort of stroke patients. Patients with MetS were more likely to be female, nonsmokers, and more likely to have a prior history of diabetes mellitus, high blood glucose and a family history of stroke than patients without MetS. During 1-year follow-up, patients with MetS had a non-significantly higher rate of stroke recurrence (7.1%) than patients without MetS (3.9%; P = 0.07). There was no difference in mortality (3.3% versus 3.5%, respectively). Multivariate Cox proportional hazards analysis (adjusting for gender, BMI, smoking, diabetes, and LDL-C) identified an association between that 1-year stroke recurrence and the presence of MetS (hazard ratio 2.30; 95% CI: 1.01–5.22) and large waist circumference (hazard ratio: 2.39; 95% CI: 1.05–5.42). However, multivariable analysis adjusting for the individual components of MetS found no significant associations between MetS and stroke recurrence. There were no associations between these parameters and mortality. Conclusions Chinese patients with symptomatic intracranial atherosclerosis who have MetS, are at higher risk of recurrent stroke than those without MetS. However, MetS was not predictive of stroke recurrence beyond its individual components and one-year mortality. PMID:23251528

    Mild Crohn's disease (CD) is classified as those patients who are ambulatory, with <10 % weight loss, are eating and drinking without abdominal mass, tenderness, obstructive symptoms, or fever, and endoscopically they have non-progressive mild findings. Initial evaluation of mild CD should focus on assessment for high-risk features requiring more aggressive therapy. In contrast to moderate-to-severe disease, where therapy is focused on mucosal healing, the management of mild CD is focused on symptom management, while exposing the individual to minimal therapeutic risks. Budesonide is the most commonly used medication for mild CD given its safety profile. Assessment of inflammatory markers, in concert with computed-tomography (CT) or magnetic resonance (MR) enterographies and endoscopic studies, should be considered in clinical remission to ensure that mucosal inflammation is not present. Endoscopic inflammation can precede clinical recurrence. Individuals with mild CD require routine vaccination, monitoring for iron-deficiency anemia and vitamin D deficiency, and colorectal cancer screening when appropriate. PMID:27448619

    Patients with obsessive-compulsive disorder (OCD) not only respond to obsessions with perseverative checking, but also engage in more general checking, irrespective of their obsessive concerns. This study investigated whether general checking is specific to OCD and exacerbated when only mild uncertainty is induced. Thirty-one patients with OCD, 26 anxiety- and 31 healthy controls performed a visual search task with eye-tracking and indicated in 50 search displays whether a target was "present" or "absent". Target-present trials were unambiguous, whereas target-absent trials induced mild uncertainty, because participants had to rely on not overlooking the target. Checking behavior was measured by assessing search time and the number of fixations, measured with an eye-tracker. Results showed that in both target-present and target-absent trials patients with OCD searched longer and made more fixations than healthy and anxiety controls. However, the difference in checking behavior between patients with OCD and the control groups was larger in target-absent trials (where mild uncertainty was induced). Anxiety and healthy controls did not differ in checking behavior. Thus, mild uncertainty appears to specifically promote checking in patients with OCD, which has implications for treatment.

    Objective: Whole human genome oligo microarrays were employed to systematically investigate the mRNA expression profile of 5-HT synthetase, transporter, receptor, and factors in 5-HT signaling pathway in peripheral blood karyocytes from pulmonary embolism (PE) patients. Methods: A total of 20 PE patients and 20 healthy subjects matched in gender and age were recruited. The human genome microarrays were performed to detect the mRNA expression profile of 5-HT synthetase, transporter, receptor, and factors in 5-HT signal pathway of two groups. The random variance model corrected t-test was used for analysis. Results: Our results showed (1) tryptophan hydroxylase (TPH1)-related gene expression was markedly down-regulated in PE patients (P < 0.01); (2) monoamine oxidases (MAO)-related gene (MAOB) expression was significantly up-regulated in PE patients (P < 0.01); (3) the expression of 17 genes of 7 5-HT receptors showed a down-regulated tendency in PE patients, and significant difference was observed in the expression of HTR1E, HTR3B, HTR4 and HTR5A between them (P < 0.05); (4) the expression of DalDAG-GEF I, Tubby, PKA and EPAC in 5-HT signal pathways was dramatically up-regulated in PE patients (P < 0.05); the expression of SPA1, RIAM, RAPL, Talin, PKC, PLC and Pyk2 was remarkably up-regulated in PE patients (P < 0.05); (5) the expression of integrin genes ITGA2B, ITGB1 and ITGB3 was significantly up-regulated in PE patients (P < 0.05). Conclusion: In PE patients, the expression of TPH1 and HTR4 was down-regulated as a negative feedback; the MAOB expression was up-regulated. Consistent with the expression of 5-HTR1E and 5-HTR4 and the abnormally activated Tubby, the expression of integrins in platelets was activated. PMID:25785024

    Background Obstructive sleep apnea (OSA) is a chronic and progressive disease. OSA is associated with increased cardiovascular morbidity and mortality, the risk being more frequently encountered with severe degrees of OSA. Increased sympathetic activation and impaired cardiac autonomic control as reflected by depressed baroreceptor reflex sensitivity (BRS) are possible mechanisms involved in the cardiovascular complications of OSA. However, it is not known at what stage of OSA that changes in BRS appear. The aim of this study was to evaluate BRS in patients with mild OSA. Methods The study population consisted of 81 overweight patients with mild OSA and 46 body weight-matched non-OSA subjects. BRS, apnea-hypopnea index, body mass index, and metabolic parameters were assessed. The phenylephrine test was used to measure BRS. Results Patients in the OSA group were slightly but significantly older than the non-OSA population (50.3±9.3 years vs 45.7±11.1 years, P=0.02). Body mass index, percentage body fat, blood pressure, fasting glucose, insulin, and lipid levels did not differ between the OSA patients and non-OSA subjects. Absolute BRS values in patients with mild OSA and non-OSA subjects (9.97±6.70 ms/mmHg vs 10.51±7.16 ms/mmHg, P=0.67) and BRS values proportional to age-related and sex-related reference values (91.4%±22.7% vs 92.2%±21.8%, P=0.84) did not differ from each other. BRS <50% of the sex-specific reference value was found in 6% of patients with mild OSA and in 2% of non-OSA subjects (P=0.29). Conclusion Patients with mild OSA did not show evidence of disturbed BRS in comparison with weight-matched non-OSA controls. PMID:26203292

    Objective To investigate the association between alcohol consumption and mortality in patients recently diagnosed with mild Alzheimer's disease (AD). Design A post hoc analysis study based on a clinical trial population. Setting The data reported were collected as part of the Danish Alzheimer's Intervention Study (DAISY), a longitudinal multicentre randomised controlled study on the efficacy of psychosocial intervention in patients with mild AD across five county districts in Denmark. Participants 321 patients with mild AD (Mini-Mental State Examination ≥20) were included. Data regarding current daily alcohol consumption were obtained from the patient's primary caregivers at inclusion. Main outcome All-cause mortality retrieved from The Danish Civil Registration System over a period of 36 months after baseline. Results Information about alcohol consumption was obtained from all 321 study participants: 8% were abstinent, 71% only had alcohol occasionally (1 or <1 unit/day), 17% had 2–3 units/day and 4% had more than 3 units/day. An analysis adjusted for a range of potential confounders demonstrated a reduced mortality for patients with moderate alcohol consumption (2–3 units/day): HR 0.23 (95% CI (0.08 to 0.69)) compared with patients who had 1 or <1 unit/day. Mortality was not significantly different in abstinent patients or in patients with an alcohol consumption of more than 3 units/day, compared with patients drinking 1 or <1 unit/day. Conclusions In this cohort of patients with mild AD, moderate alcohol consumption (2–3 units/day) was associated with a significantly lower mortality over a period of 36 months. Further studies are needed in this area. These may especially focus on the association between alcohol consumption and cognitive decline in patients with AD. PMID:26656463

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

    Background: With increasing frequency, platelet-rich plasma (PRP) preparations have been used to treat cartilage lesions to regenerate tissue homeostasis and retard the progression of knee osteoarthritis (OA). Purpose: To determine the effectiveness of intra-articular PRP injections in active patients with knee OA and to evaluate clinical outcomes in patients with and without previous surgical treatment for cartilage lesions. Study Design: Case series. Materials and Methods: Fifty patients with knee OA were followed for a minimum of 12 months. All were treated with 2 intra-articular injections of autologous PRP. Twenty-five patients had undergone a previous operative intervention for cartilage lesions, whereas 25 had not. Operated patients had undergone either cartilage shaving or microfracture. Multiple evaluative scores were collected at pretreatment and at 6 and 12 months posttreatment. The required sample of patients was determined beforehand by using statistical power analysis; International Knee Documentation Committee (subjective) score was defined as the primary parameter. A P value of less than 0.05 was considered statistically significant. General linear model–repeated measure test evaluated within-time improvement for each variable for all patients. Post hoc test with Bonferroni adjustment for multiple comparisons was performed to investigate the significance in improvement within time evaluations for each variable for the total sample. The differences in improvement between operated and nonoperated patients were also investigated, as were those between sexes. Results: All patients showed significant improvement in all scores at 6 and 12 months (P < 0.01) and returned to previous activities. No significant difference in improvement was found between the evaluated subgroups (P < 0.01). Conclusions: The PRP treatment showed positive effects in patients with knee OA. Operated and nonoperated patients showed significant improvement by means of diminishing

    Differential diagnosis of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) is based on the presence of diverse symptoms, including fever (≥38.5°C), rigors, malaise, lethargy, flank pain, hematuria, suprapubic discomfort, dysuria, and urgent or frequent urination. There is consensus in the medical community that ASB warrants antibiotic treatment only for patients undergoing urological procedures that lead to mucosal bleeding, catheterized individuals whose ASB persists for more than 48 h after catheter removal, and pregnant women. Pyuria is associated with UTI and implicates host immune responses via release of antibacterial effectors and phagocytosis of pathogens by neutrophils. Such responses are not sufficiently described for ASB. Metaproteomic methods were used here to identify the pathogens and evaluate molecular evidence of distinct immune responses in cases of ASB compared to UTI in elderly patients who were hospitalized upon injury. Neutrophil-driven inflammatory responses to invading bacteria were not discernible in most patients diagnosed with ASB compared to those with UTI. In contrast, proteomic urine analysis for trauma patients with no evidence of bacteriuria, including those who suffered mucosal injuries via urethral catheterization, rarely showed evidence of neutrophil infiltration. The same enzymes contributing to the synthesis of leukotrienes LTB4 and LTC4, mediators of inflammation and pain, were found in the UTI and ASB cohorts. These data support the notion that the pathways mediating inflammation and pain in most elderly patients with ASB are not quantitatively different from those seen in most elderly patients with UTI and warrant larger clinical studies to assess whether a common antibiotic treatment strategy for elderly ASB and UTI patients is justified.

    Purpose To compare sleep quality and sustained attention of patients with Upper Airway Resistance Syndrome (UARS), mild Obstructive Sleep Apnea (OSA) and normal individuals. Methods UARS criteria were presence of excessive daytime sleepiness (Epworth Sleepiness Scale—ESS—≥ 10) and/or fatigue (Modified Fatigue Impact Scale—MFIS—≥ 38) associated to Apnea/hypopnea index (AHI) ≤ 5 and Respiratory Disturbance Index (RDI) > 5 events/hour of sleep or more than 30% of total sleep time with flow limitation. Mild OSA was considered if the presence of excessive daytime sleepiness (ESS ≥ 10) and/or fatigue (MFIS ≥ 38) associated to AHI ≥ 5 and ≤ 15 events/hour. “Control group” criteria were AHI < 5 events/hour and RDI ≤ 5 events/hour and ESS ≤ 9, without any sleep, clinical, neurological or psychiatric disorder. 115 individuals (34 UARS and 47 mild OSA patients and 34 individuals in “control group”), adjusted for age, gender, body mass index (BMI) and schooling years, performed sleep questionnaires and sustained attention evaluation. Psychomotor Vigilance Task (PVT) was performed five times (each two hours) from 8 a.m. to 4 p.m. Results UARS patients had worse sleep quality (Functional Outcomes of Sleep Questionnaire—FOSQ—and Pittsburgh Sleep Quality Index—PSQI: p < 0.05) and more fatigue than mild OSA patients (p = 0.003) and scored significantly higher in both Beck inventories than “control group” (p < 0.02). UARS patients had more lapses early in the morning (in time 1) compared to the results in the afternoon (time 5) than mild OSA (p = 0.02). Mild OSA patients had more lapses in times 2 than in time 5 compared to “control group” (p = 0.04). Conclusions UARS patients have a worse sleep quality, more fatigue and a worse early morning sustained attention compared to mild OSA. These last had a worse sustained attention than controls.

    Preterm delivery is the leading cause of neonatal mortality and morbidity. The rate of preterm births has been estimated to be about 15 million, which accounts for 11.1% of all live births worldwide. The purpose of this study was to evaluate the cervico-vaginal (CVF) cytokine IL-6 and fetal fibronectin (fFN) status as predictors of preterm delivery in patients with symptoms of preterm labor. Patients with symptoms suggestive of preterm labor were recruited from September 2013 to March 2014. Vaginal swabs were taken for fetal fibronectin test (fFN) and CVF IL-6. Antibiotics, steroids and tocolytics were administered, where appropriate. The outcome was measured by the occurrence of preterm delivery within 14 days from the day of hospital admission. Cut-off value of 1305 pg/mL for the concentration of IL-6 in the CVF was the best predictor of preterm delivery, with the sensitivity of 69.4% and specificity of 68.2%. Patients with positive fFN test had the OR of 6.429 (95%CI 1.991-20.758) to deliver prematurely. The multivariate analysis of combined fFN and CVF IL-6 tests resulted in risk of 86.7% to deliver prematurely, if both tests were positive. The combination of both tests performed better than the individual tests and decreased the false positive rate, which in turn reduced the chances for inappropriate patient treatment, bringing down the costs.

    The assessment of results of medical treatment, angioplasty and coronary bypass surgery in diabetic coronary patients is difficult because of the absence of distinction in the subgroups of type 1 and 2 diabetes and of stable and unstable angina. With respect to medical therapy, betablockers are practically without deleterious effects and are effective in diabetic populations. The same is true of other antianginal drugs. Conventional coronary angioplasty is associated with poorer results than the general population in the long-term, partly because of progression of the coronary artery disease and partly because of an increased incidence of restenosis. The use of stents improves these results, which are similar to those of the general population with single vessel disease or those without proteinuria. Coronary bypass surgery, despite a certain perioperative morbidity, is associated with an identical survival rate at 5 years as non-diabetics, providing the internal mammary artery is grafted. The comparison between these methods is resumed in the ACIP study which opposes the 3 strategies, in Morris et al's study comparing medical and surgical approaches and, finally, in the recent BARI trial where patients were randomly allocated to angioplasty or surgery. It would appear that the surgical strategy gives better results in multivessel disease. However, many reserves have been voiced because of the small numbers of patients, the high number of excluded patients and the fact that recent progress in angioplasty with widespread use of stenting associated with the prescription of new antiaggregant drugs was not taken into account.

    A variety of approaches have been used to alleviate symptoms in postural tachycardia syndrome (POTS). Drugs reported to be of benefit include midodrine, propranolol, clonidine, and phenobarbital. Other measures used include volume expansion and physical countermaneuvers. These treatments may influence pathophysiologic mechanisms of POTS such as alpha-receptor dysfunction, beta-receptor supersensitivity, venous pooling, and brainstem center dysfunction. The authors prospectively studied hemodynamic indices and symptom scores in patients with POTS who were acutely treated with a variety of interventions. Twenty-one subjects who met the criteria for POTS were studied (20 women, 1 man; mean age, 28.7 +/- 6.8 y; age range, 14-39 y). Patients were studied with a 5-minute head-up tilt protocol, ECG monitoring, and noninvasive beat-to-beat blood pressure monitoring, all before and after the administration of an intervention (intravenous saline, midodrine, propranolol, clonidine, or phenobarbital). The hemodynamic indices studied were heart rate (ECG) and systolic, mean, and diastolic blood pressure. Patients used a balanced verbal scale to record any change in their symptoms between the tilts. Symptom scores improved significantly after the patients received midodrine and saline. Midodrine and propranolol reduced the resting heart rate response to tilt (p <0.005) and the immediate and 5-minute heart rate responses to tilt (p <0.002). Clonidine accentuated the immediate decrease in blood pressure on tilt up (p <0.05). It was concluded that midodrine and intravenous saline are effective in decreasing symptoms on tilt in patients with POTS when given acutely. Effects of treatments on heart rate and blood pressure responses generally reflected the known pharmacologic mechanisms of the agents.

    Patients that suffer a mild traumatic brain injury (TBI) with intracranial hemorrhage are commonly admitted to an intensive care unit with repeat imaging in 12 to 24 hours. This is costly to the health-care system. This study aimed to evaluate this practice and to identify criteria to triage patients to lower levels of monitored care. A retrospective review was performed at a university-based Level I trauma center. Patients with mild TBI were included. Data were collected on demographics, neurological status at 6, 12, and 24 hours, CT scan results, and medical or surgical interventions were required. A total of 389 patients were evaluated, 53 had a documented neurological decline while being admitted. Factors found to be associated with a neurological decline included Glasgow Coma Scale (GCS) < 15 (P = 0.002), age greater than 55 (P < 0.001), and warfarin use (P = 0.039). Aspirin and Plavix were not associated with neurological decline. No patient age <55 with a GCS of 15 had a documented decline. Several risk factors were found to be associated with neurological decline after mild TBI. These include age, GCS < 15, and warfarin use. Patients aged <55 with GCS 15, posed minimal risk for deterioration. Patients aged <55 and with a GCS of 15 can be admitted to a monitored step-down bed with less frequent neurological checks.

    Background Chronic pain conditions are highly prevalent in patients with mild traumatic brain injury. Supraspinal diffuse axonal injury is known to dissociate brain functional connectivity in these patients. The effect of this dissociated state on supraspinal pain network is largely unknown. A functional magnetic resonance imaging study was conducted to compare the supraspinal pain network in patients with mild traumatic brain injury to the gender and age-matched healthy controls with the hypothesis that the functional connectivities of the medial prefrontal cortices, a supraspinal pain modulatory region to other pain-related sensory discriminatory and affective regions in the mild traumatic brain injury subjects are significantly reduced in comparison to healthy controls. Results The mild traumatic brain injury group (N = 15) demonstrated significantly (P < 0.01, cluster threshold > 150 voxels) less activities in the thalamus, pons, anterior cingulate cortex, insula, dorsolateral prefrontal cortex, and medial prefrontal cortices than the healthy control group (N = 15). Granger Causality Analyses (GCA) indicated while the left medial prefrontal cortices of the healthy control group cast a noticeable degree of outward (to affect) causality inference to multiple pain processing related regions, this outward inference pattern was not observed in the mild traumatic brain injury group. On the other hand, only patients’ bilateral anterior cingulate cortex received multiple inward (to be affected) causality inferences from regions including the primary and secondary somatosensory cortices and the inferior parietal lobe. Resting state functional connectivity analyses indicated that the medial prefrontal cortices of the mild traumatic brain injury group demonstrated a significantly (P < 0.01, F = 3.6, cluster size > 150 voxels) higher degree of functional connectivity to the inferior parietal lobe, premotor and secondary somatosensory cortex

    Noopept is a neuroprotector and nootropics. Literature data revealed the treatment effect of noopept on mild cognitive impairment in patients with discirculatory encephalopathy. The present open prospective study included 60 patients with stroke treated with noopept during 12 months. Cognitive functions were assessed before and after treatment using neuropsychological tests. An analysis of MMSE scores and lateral and categorical associations revealed the significant improvement of cognitive functions after 2 months in patients of the main group compared to the controls. The global assessment of efficacy revealed the mild improvement in the main group while no changes were found in the control group. The results have demonstrated that noopept, used in dose 20 mg daily during 2 months, improves cognitive functions in stroke patients and has a high level of safety. PMID:22500312

    Background Atherosclerosis is a major cause of cerebrovascular disease. Matrix metalloproteinases (MMPs) play an important role in matrix degradation within the atherosclerotic lesion leading to plaque destabilization and ischemic stroke. We hypothesized that MMP-7 could be involved in this process. Methods Plasma levels of MMP-7 were measured in 182 consecutive patients with moderate (50–69%) or severe (≥70%) internal carotid artery stenosis, and in 23 healthy controls. The mRNA levels of MMP-7 were measured in atherosclerotic carotid plaques with different symptomatology, and based on its localization to macrophages, the in vitro regulation of MMP-7 in primary monocytes was examined. Results Our major findings were (i) Patients with carotid atherosclerosis had markedly increased plasma levels of MMP-7 compared to healthy controls, with particularly high levels in patients with recent symptoms (i.e., within the last 2 months). (ii) A similar pattern was found within carotid plaques with markedly higher mRNA levels of MMP-7 than in non-atherosclerotic vessels. Particularly high protein levels of MMP-7 levels were found in those with the most recent symptoms. (iii) Immunhistochemistry showed that MMP-7 was localized to macrophages, and in vitro studies in primary monocytes showed that the inflammatory cytokine tumor necrosis factor-α in combination with hypoxia and oxidized LDL markedly increased MMP-7 expression. (iv) During the follow-up of patients with carotid atherosclerosis, high plasma levels of MMP-7 were independently associated with total mortality. Conclusion Our findings suggest that MMP-7 could contribute to plaque instability in carotid atherosclerosis, potentially involving macrophage-related mechanisms. PMID:24400123

    Previous data have indicated that carotid plaque ulceration is a strong predictor of cerebrovascular events. Standard ultrasound and color Doppler ultrasound (CDUS) scans have poor diagnostic accuracy for the detection of carotid plaque ulceration. The aim of the present prospective study was to assess the value of contrast-enhanced ultrasound (CEUS) scans for the detection of carotid plaque ulceration. The Institutional Ethics Committee approved the study protocol, and all patients provided informed consent. The patients had symptomatic stenosis of the internal carotid artery and underwent carotid computed tomographic angiography as part of their clinical evaluation. All patients underwent a CDUS examination in conjunction with CEUS. Carotid plaque ulceration was defined as the presence of ≥1 disruptions in the plaque-lumen border ≥1 × 1 mm. Carotid computed tomographic angiography was used as reference technique. The study population consisted of 20 patients (mean age 64 ± 9 years, 80% men), and 39 carotid arteries were included in the present analysis. Computed tomographic angiography demonstrated that the plaque surface was smooth in 15 (38%), irregular in 7 (18%) and ulcerated in 17 (44%) carotid arteries. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CDUS for the detection of ulceration was 29%, 73%, 54%, 46%, and 57%, respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CEUS for the detection of ulceration was 88%, 59%, 72%, 63%, and 87%, respectively. CEUS had superior sensitivity and diagnostic accuracy for the assessment of carotid plaque ulceration compared with CDUS. CEUS improved the intrareader and inter-reader variability for the assessment of carotid plaque ulceration compared with CDUS. In conclusion, CEUS could be an additional method for the detection of carotid plaque ulceration. The role of CDUS for the assessment of

    Both chronic kidney disease and osteoporosis are frequent conditions in the general population. Most drugs for treating osteoporosis seem safe in terms of affecting renal function for patients with mildly to moderate decreased renal function. There are very few data on the efficacy (reduction in fracture risk) or safety in patients with severely decreased renal function (glomerular filtration rate < 30 ml/min) or on dialysis.

    Background New approaches to assess outcome in schizophrenia include multidimensional measures such as remission, cognition, psychosocial functioning, and quality of life. Clinical and psychosocial measures have been recently introduced to assess functional outcome. Objective The study presented here was designed to examine the rates of symptomatic remission, psychosocial remission, global functioning, and clinical global impressions in a sample of schizophrenia outpatients in order to assess functional remission and to identify predictive factors for functional remission. Methods A total of 168 consecutive Mexican outpatients receiving pharmacological treatment at the National Institute of Psychiatry in Mexico City were enrolled in a cross-sectional study. Symptomatic remission was assessed according to the definition and criteria proposed by the Remission in Schizophrenia Working Group using the Positive and Negative Symptom Scale. Psychosocial remission was assessed according to Barak criteria using the Psychosocial Remission in Schizophrenia scale. Functioning was measured with the Global Assessment of Functioning, and clinical outcome with the Clinical Global Impressions (CGI) Scale. Results Findings showed that 45.2% of patients fulfilled the symptomatic remission criteria, 32.1% achieved psychosocial remission, and 53% reported adequate functioning. However, the combination of these three outcome criteria – symptomatic, psychosocial remission, and functioning – indicated that 14.9% of the patients achieved our predefined functional remission outcome. The logistic regression model included five predictive variables for functional remission: (1) being employed, (2) use of atypical antipsychotics, (3) lower number of medications, (4) lower negative symptom severity, and (5) lower excitement symptom severity. Conclusion The study demonstrated that symptomatic remission, psychosocial remission, and functioning could be achievable goals for a considerable

    To determine the renovascular effects of nonprescription ibuprofen in the maximum labeled over-the-counter (OTC) dosage for 7 days, and to compare these effects with those of two other available OTC analgesics, aspirin and acetaminophen, we evaluated 25 elderly patients with mild thiazide-treated hypertension and mild renal insufficiency. Under double-blind conditions, patients were randomly allocated to one of three treatment groups: ibuprofen 400 mg 3 times/day, aspirin 650 mg 3 times/day, or acetaminophen 650 mg 3 times/day. Blood pressure and indexes of renal function (blood urea nitrogen, creatinine clearance, serum electrolytes) were measured over 7 days in a clinical research center. None of the treatments had a clinically significant effect on blood pressure. Renal function indexes also remained unchanged during all three treatments. We conclude that elderly patients with mild thiazide-treated hypertension and mild renal insufficiency seem not to be at risk of developing additional renal compromise or of having their hypertension control diminished by treatment with these OTC analgesics for 7 days.

    Coarctation of the aorta (COA) is an aortic obstruction. A peak-to-peak trans-coarctation pressure gradient (PKdP) of greater than 20 mmHg warns severe COA and the need for interventional/surgical repair. The optimal method and timing of intervention remain uncertain especially for mild COA (PKdP <20 mmHg); even it is unclear if mild COA should be treated at all. Although it was recently suggested that treatment strategies for mild COA may need to be redefined as transcatheter interventions emerge, benefits of such interventions are unclear. We investigated the effects of transcatheter interventions on the aorta and left ventricle (LV) hemodynamics in 11 patients with mild COA using a developed computational fluid dynamics and lumped parameter modeling framework along with particle image velocimetry and clinical measurements. Such interventions can improve aortic hemodynamics to some extent (e.g., time-averaged wall shear stress and kinetic energy were reduced by about 20%). However there is no concomitant effect on the LV hemodynamics (e.g., stroke work and LV pressure were reduced by only less than 4%). Our computational approach can effectively predict clinical conditions. Herein one must question intervention for mild COA, as it has limited utility in reducing myocardial strain.

    CT colonography (CTC) is also referred to as virtual colonoscopy and is being used with increasing frequency in radiological practice. While there are still no generally accepted, clear-cut indications for its use in mass colorectal cancer screening, there is evidence that this investigation is useful in patients in whom colonoscopy has not been successful or who have known stenotic lesions in the colon. Recent results of significant comparative studies of CTC and conventional colonoscopy will have some influence on the future place of CTC in screening for cancer of the bowel; they show the great potential of CT-aided bowel examination.

    Abstract Background: Pes anserine bursitis strongly affects quality of life in patients with osteoarthritis. Treatment includes nonsteroidal anti-inflammatory drugs (NSAIDs), physiotherapy, and injections of corticosteroid, with highly variable responses; recovery can take 10 days to 36 months. Mesotherapy is a minimally invasive technique consisting of subcutaneous injections of bioactive substances. The goal is to modulate the pharmacokinetics of the injected substance and prolong the effects at a local level. Objective: To evaluate the effects of mesotherapy with diclofenac for anserine bursitis associated with knee osteoarthritis. Methods: One hundred and seventeen patients with anserine bursitis associated with grade II Kellgren-Lawrence knee osteoarthritis, assessed by clinical, radiographic, and ultrasonographic examination, were evaluated and treated. They were randomly divided into two groups (A, mesotherapy; B, control). Group A completed nine sessions of mesotherapy with sodium diclofenac (25 mg/1 mL; Akis®, IBSA, Lugano, Switzerland), 1 mL for each session, three times per week. Group B received 21 oral administrations of sodium diclofenac (50 mg; Voltaren®, Novartis, Parsippany, NJ), once a day for 3 weeks. Primary outcome measures were pain intensity assessed by visual analogue scale (VAS), along with ability to perform activities of daily living, ability to participate in sports, level of pain, symptoms, and quality of life, as assessed by the Knee injury and Osteoarthritis Outcome Score. These measures were performed before and after the treatment period and at 30 and 90 days' follow up. Results: In both groups pain level decreased significantly after the treatment period. Ultrasonography showed a reduction of the hypoechoic area related to anserine bursitis only in group A. Conclusion: Administration of conventional NSAIDs (diclofenac) by mesotherapy is effective in managing anserine bursitis in knee osteoarthritis in the short term and

    To evaluate the efficiency menantine (antagonist of NMDA-type glutamate receptor) for treatment of the mild stage of Alzheimer and vascular dementia, we conducted a comprehensive neurological, experimental psychological, neurophysiological examination of 33 patients. It was found that the treatment course with memantine, 5-10 mg daily during 3 months resulted in reducing the severity of cognitive impairment, improved bioelectric activity of the brain in patients with dementia, and also helped to improve the patients' behavior, which resulted in stress loads on the surrounding people. It is shown that the treatment was well tolerated, and memantine may be recommended as one of the drugs for treatment of cognitive impairment accompanying aging in the mild stage of dementia of different genesis.

    Objective The present study was aimed at evaluating the effective radiation dose in patients submitted to PET/CT for the diagnosis of mild cognitive impairment. Materials and Methods TLD-100 detectors inserted into an Alderson Rando® anthropomorphic phantom were utilized to measure the absorbed dose coming from the CT imaging modality. The anthropomorphic phantoms (male and female adult versions) were submitted to the same technical protocols for patients’ images acquisition. The absorbed dose resulting from the radiopharmaceutical injection was estimated by means of the model proposed by the ICRP publication 106. Results The effective dose in patients submitted to this diagnostic technique was approximately (5.34 ± 1.99) mSv. Conclusion Optimized protocols for calculation of radioactive activity injected into patients submitted to this diagnostic technique might contribute to reduce the effective radiation dose resulting from PET/CT in the diagnosis of mild cognitive impairment.

    Introduction Psoriasis is a chronic inflammatory disease associated with a significantly higher morbidity and various comorbidities (obesity, metabolic syndrome, diabetes). Previous studies focused mainly on patients with severe psoriasis who were found to have increased markers of early atherosclerosis, higher intima-media thickness (IMT) values. Aim To evaluate the association between the severity or duration of psoriasis and carotid IMT in patients with mild and moderate psoriasis. Material and methods We studied seventy four patients with mild and moderate psoriasis. Clinical assessment and common carotid artery (CCA) IMT measurements were performed in all patients. Results The mean CCA IMT value was 1.03 ±0.37 mm, mean PASI score (psoriasis area severity index) was 18.6 ±10.5. There was a significant association between PASI score and IMT values (r = 0.33; p = 0.007) adjusted for age, psoriasis duration, blood pressure and smoking. However, we found no correlations between carotid IMT and disease duration or other clinical variables. Conclusions The severity of psoriasis is associated with carotid IMT even in patients with mild and moderate psoriasis. PMID:27605900

    Introduction COPD exacerbation negatively impacts the patient’s quality of life and lung function, increases mortality, and increases socioeconomic costs. In a real-world setting, the majority of patients with COPD have mild-to-moderate airflow limitation. Therefore, it is important to evaluate COPD exacerbation in patients with mild-to-moderate airflow limitation, although most studies have focused on the patients with moderate or severe COPD. The objective of this study was to evaluate factors associated with COPD exacerbation in patients with mild-to-moderate airflow limitation. Methods Patients registered in the Korean COPD Subtype Study cohort were recruited from 37 tertiary referral hospitals in Korea. We obtained their clinical data including demographic characteristics, past medical history, and comorbidities from medical records. Patients were required to visit the hospital to document their COPD status using self-administered questionnaires every 6 months. Results A total of 570 patients with mild-to-moderate airflow limitation were enrolled. During the first year of follow-up, 30.5% patients experienced acute exacerbation, with exacerbations being more common in patients with poor lung function. Assessed factors associated with COPD exacerbation included COPD assessment test scores, modified Medical Research Council dyspnea assessment test scores, St George’s Respiratory Questionnaire for COPD scores, a previous history of exacerbation, and histories of pneumonia and allergic rhinitis. Logistic regression tests revealed St George’s Respiratory Questionnaire for COPD scores (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00–1.04; P=0.034), a previous history of exacerbation (OR, 3.12; 95% CI, 1.35–7.23; P=0.008), and a history of pneumonia (OR, 1.85; 95% CI, 1.06–3.25; P=0.032) as risk factors for COPD exacerbation. Conclusion Our results suggest that COPD exacerbation in patients with mild-to-moderate airflow limitation is associated

    Osteonecrosis (ON) is a potentially disabling complication encountered in children who receive chemotherapy for acute lymphoblastic leukemia (ALL). Considering the possible effect of ethnic difference on the clinical features of symptomatic ON in pediatric ALL, we retrospectively evaluated 245 children with ALL who were treated at Chang Gung Memorial Hospital, Linkou, between 2002 and 2011. Six (2.4 %) patients developed symptomatic ON in a total of 17 sites during the follow-up period. Diagnosis of ON was confirmed by X-ray in seven, magnetic resonance imaging in two, and bone scan in three patients. The estimated cumulative incidence of symptomatic ON in newly diagnosed ALL was 3.4 % at 8 years. Four patients received ON-directed surgical interventions, including total hip replacement in three and arthroplasty in one. The incidence of ON was significantly higher among girls (P = 0.03), patients >10 years old (P = 2.2 × 10(-4)), and patients who had received more intensive chemotherapy regimen (P = 0.02). These results indicate that the incidence and risk factors in our institute were similar to those observed in Western countries. Future studies surveying the impact on the quality of life of childhood ALL survivors in Taiwan are warranted. PMID:25840770

  5. Intervention versus standard medical treatment in patients with symptomatic occlusion of the internal carotid artery: a randomised oxygen-15 PET study

    2013-01-01

    Background The aim of this randomised pilot study was to investigate the haemodynamic effects measured by oxygen-15 positron emission tomography (PET) of interventional treatment consisting of either endarterectomy or endovascular treatment of stenosed cerebropetal arteries, or tapering of antihypertensive medication in comparison with standard medical treatment alone in patients with symptomatic internal carotid artery (ICA) occlusion. Methods Twenty-three patients with symptomatic ICA occlusion underwent PET scanning at baseline and after 3 months. Twelve patients were randomised to intervention (either endarterectomy or endovascular treatment of stenosed cerebropetal arteries, or tapering of antihypertensive medication) and 11 to standard medical treatment alone. Primary outcome was a change in cerebral blood flow (CBF), cerebral blood volume (CBV) and/or oxygen extraction fraction (OEF) after 3 months measured by PET. Results There were no differences in changes in CBF, CBV or OEF between the two groups. Only patients with compromised perfusion at presentation showed a borderline significant increase in CBF of 2.8 mL/min/100 mL (95% confidence interval 0.0 to 5.7) after intervention (n = 7). Conclusion This pilot study shows that in patients with symptomatic ICA occlusion, oxygen-15 PET did not detect differences in improvement of CBF, CBV or OEF between interventional and standard treatment.

    This study evaluated the working memory performance of 18 patients experiencing their first onset of mild depression without treatment and 18 healthy matched controls. The results demonstrated that working memory impairment in patients with mild depression occurred when memorizing the position of a picture but not when memorizing the pictures themselves. There was no significant difference between the two groups in the emotional impact on the working memory, indicating that the attenuation of spatial working memory was not affected by negative emotion; however, cognitive control selectively affected spatial working memory. In addition, the accuracy of spatial working memory in the depressed patients was not significantly reduced, but the reaction time was significantly extended compared with the healthy controls. This finding indicated that there was no damage to memory encoding and function maintenance in the patients but rather only impaired memory retrieval, suggesting that the extent of damage to the working memory system and cognitive control abilities was associated with the corresponding depressive symptoms. The development of mild to severe depressive symptoms may be accompanied by spatial working memory damage from the impaired memory retrieval function extending to memory encoding and memory retention impairments. In addition, the impaired cognitive control began with an inadequate capacity to automatically process internal negative emotions and further extended to impairment of the ability to regulate and suppress external emotions. The results of the mood-congruent study showed that the memory of patients with mild symptoms of depression was associated with a mood-congruent memory effect, demonstrating that mood-congruent memory was a typical feature of depression, regardless of the severity of depression. This study provided important information for understanding the development of cognitive dysfunction. PMID:26730597

    Osteoarthritis (OA) of the hip is a common cause of hip pain. The arthroscopic management of patients with femoro-acetabular impingement (FAI) has been reported to yield good outcomes. The purpose of this study was to report on outcome following the arthroscopic treatment of patients with FAI in the presence of mild to moderate OA. Seventy-five patients undergoing arthroscopic surgery for FAI, all with preoperative radiological signs of mild to moderate OA were prospectively included in this study. A 2-year follow-up, using web-based patient-reported outcome measures, including the International Hip Outcome Tool (iHOT-12), Copenhagen Hip and Groin Outcome (HAGOS), EQ-5D, Hip Sports Activity Scale (HSAS) for physical activity level and a visual analogue scale (VAS) for overall hip function, was performed, complemented by a radiographic evaluation. At follow-up (mean 26 months, SD 5), five patients (7%) had undergone total hip arthroplasty, leaving 70 patients for the analysis. Preoperative scores compared with those obtained at the 2-year follow-up revealed significant improvements (P < 0.0001) for all measured outcomes; the iHOT-12 (42 versus 65), VAS for global hip function (48 versus 68), HSAS (2.5 versus 3), EQ5D index (0.62 versus 0.76), EQ VAS (69 versus 75) and different HAGOS subscales (54 versus 72, 47 versus 67, 56 versus 75, 40 versus 61, 33 versus 56, 31 versus 55). At follow-up, 56 (82%) patients reported that they was satisfied with the outcome of surgery. Arthroscopic treatment for patients with FAI in the presence of mild to moderate OA resulted in statistically significant and clinically relevant improvements in outcome measures related to pain, symptoms, function, physical activity level and quality of life in the majority of patients.

    Objectives: To compare tooth size between subjects with mild, moderate and severe hypodontia and a control group. Material and Methods: The study comprised 120 patients with hypodontia divided into three groups of 40 mild (≤2 teeth congenitally missing), 40 moderate (3-5 teeth congenitally missing) and 40 severe (≥6 teeth congenitally missing) hypodontia; and 40 age and sex matched controls. Tooth size was recorded by measuring the mesiodistal and buccolingual dimensions of all fully erupted teeth on study models using digital callipers and compared between all hypodontia and control groups using Two-way ANOVA and Post Hoc Tests of subgroup comparison. Results: Two-way ANOVA revealed patients with hypodontia had significantly smaller mesiodistal and buccolingual tooth dimensions compared with controls (p<0.05). Furthermore patients with more severe hypodontia demonstrated significantly smaller tooth dimensions than those in the mild and moderate hypodontia subgroups (p<0.05). The most affected tooth in terms of tooth size reduction was the maxillary lateral incisor and the least affected tooth was the mandibular first molar. Conclusion: Patients with hypodontia have smaller tooth dimensions than control. Tooth size appears to be affected by the degree of hypodontia, with severe hypodontia having a greater effect on tooth size reduction. The findings of this study may contribute to understanding the aetiology of hypodontia and aid the multidisciplinary management of this complex condition. PMID:27583048

    2016-01-01

    Background: Tremor affects 25% to 58% of patients with multiple sclerosis (MS) and is associated with poor prognosis and increased disability. MS-related tremor is difficult to treat, and data regarding patient-reported characterization and response to treatment are limited. We describe the symptomatic treatment of tremor in 508 enrollees in the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry who self-reported tremor. Methods: From 777 surveys sent to NARCOMS participants who indicated mild or greater tremor using the Tremor and Coordination Scale, we compiled data regarding disability, tremor severity, symptomatic medication use, and reported response to medications. Results: Symptomatic medications reported to reduce tremor were used by 238 respondents (46.9%). Symptomatic medication use was associated with increased rates of unemployment and disability, and many other characteristics were similar between groups. Symptomatic drug use was more likely in participants reporting moderate (53.9%) or severe (51.3%) tremor than in those with mild (36.6%) or totally disabling (35.0%) tremor. This disparity held true across multiple tremor severity scores. The most commonly used drug classes were anticonvulsants (50.8%) and benzodiazepines (46.2%), with gabapentin and clonazepam used most often in their respective classes. Conclusions: Tremor in MS remains poorly treated; less than half of the participants reported benefit from symptomatic medications. Patients with moderate-to-severe tremor are more likely to report tremor benefit than are those with mild or disabling tremor. γ-Aminobutyric acid–active medications were most commonly reported as beneficial.

    Background: Many studies showed a better recovery of cognitive function after administration of exogenous lactate during moderate-severe traumatic brain injury. However, the study evaluating lactate effect on mild traumatic brain injury is still limited. Aims: To evaluate the effect of exogenous lactate on cognitive function in mild traumatic brain injury patients. Settings and Design: Prospective, single blind, randomized controlled study on 60 mild traumatic brain injury patients who were undergoing neurosurgery. Materials and Methods: Subjects were randomly assigned into hyperosmolar sodium lactate (HSL) group or hyperosmolar sodium chloride (HSS) group. Patients in each group received either intravenous infusion of HSL or NaCl 3% at 1.5 ml/KgBW within 15 min before neurosurgery. During the surgery, patients in both groups received maintenance infusion of NaCl 0.9% at 1.5 ml/KgBW/hour. Statistical Analysis: Cognitive function, as assessed by Mini-Mental State Examination (MMSE) score at 24 h, 30 and 90 days post-surgery, was analyzed by Anova repeated measures test. Results: The MMSE score improvement was significantly better in HSL group than HSS group (P < 0.001). In HSL group the MMSE score improved from 16.00 (13.75-18.00) at baseline to 21.00 (18.75-22.00); 25.00 (23.75-26.00); 28.00 (27.00-29.00) at 24 h, 30, 90 days post-surgery, respectively. In contrast, in HSS group the MMSE score almost unchanged at 24 h and only slightly increased at 30 and 90 days post-surgery. Conclusions: Hyperosmolar sodium lactate infusion during mild traumatic brain injury improved cognitive function better than sodium chloride 3%. PMID:27057222

    Acute pancreatitis and acalculous cholecystitis have been occasionally reported in primary acute symptomatic Epstein-Barr virus infection. We completed a review of the literature and retained 48 scientific reports published between 1966 and 2016 for the final analysis. Acute pancreatitis was recognized in 14 and acalculous cholecystitis in 37 patients with primary acute symptomatic Epstein-Barr virus infection. In all patients, the features of acute pancreatitis or acalculous cholecystitis concurrently developed with those of primary acute symptomatic Epstein-Barr virus infection. Acute pancreatitis and acalculous cholecystitis resolved following a hospital stay of 25days or less. Acalculous cholecystitis was associated with Gilbert-Meulengracht syndrome in two cases. In conclusion, this thorough analysis indicates that acute pancreatitis and acalculous cholecystitis are unusual but plausible complications of primary acute symptomatic Epstein-Barr virus infection. Pancreatitis and cholecystitis deserve consideration in cases with severe abdominal pain. These complications are usually rather mild and resolve spontaneously without sequelae. PMID:27434148

    A group of 408 catheterised patients who had mild angina or myocardial infarction without angina was selected in conformity with the criteria for entry into a previously reported randomised trial. Medical treatment had been chosen initially by the cardiologist, referring physician, or the patient, although 27% had late operation. Five year survival rates were 91% and 72% for mild angina with high or low ejection fractions and 85% for those who had myocardial infarction without subsequent angina. Survival rates were 95%, 88%, and 80% for one, two, and three artery disease respectively. For patients who had ejection fractions of at least 0.50, five year survivals were 95%, 89%, and 83% for one, two, and three artery involvement respectively. Good left ventricular function, single artery disease, and a short history were favourable prognostic variables in multivariate analysis of patients who had angina pectoris. Statistical methods of dealing with patients who had late operation influenced calculated survival, especially for patients at relatively high risk. The lower survival rates for the whole group and most subsets compared with survival rates in the randomised trial may be of clinical importance. PMID:3756038

The hippocampus, which plays an important role in the consolidation of information from short-term memory to long-term memory, is a heterogeneous structure that consists of several anatomically and functionally distinct subfields. However, whether distinct hippocampal subfields are differentially and selectively affected by svMCI pathology and whether these abnormal changes in hippocampal subfields are different between svMCI and aMCI patients are largely unknown. A total of 26 svMCI patients, 26 aMCI patients and 26 healthy controls matched according to age, gender and years of education were enrolled in this study. We utilized an automated hippocampal subfield segmentation method provided by FreeSurfer to estimate the volume of several hippocampal subfields, including the cornu ammonis (CA) areas, the dentate gyrus (DG), the subiculum and the presubiculum. Compared with controls, the left subiculum and presubiculum and the right CA4/DG displayed significant atrophy in patients with svMCI. Interestingly, we also found significant differences in the volume of the right CA1 between the svMCI and aMCI groups. Taken together, our results reveal region-specific vulnerability of hippocampal subfields to svMCI pathology and identify distinct hippocampal subfield atrophy patterns between svMCI and aMCI patients.

    Mild traumatic brain injury (TBI) is often an invisible injury that is poorly understood and its sequelae can be difficult to diagnose. Recent neuroimaging studies on patients diagnosed with mild TBI (mTBI) have demonstrated an increase in hyperintense brain lesions on T2-weighted MR images. This paper presents an in-depth analysis of the multi-modal and morphological properties of T2 hyperintensity lesions among service members diagnosed with mTBI. A total of 790 punctuate T2 hyperintensity lesions from 89 mTBI subjects were analyzed and used to characterize the lesions based on different quantitative measurements. Morphological analysis shows that on average, T2 hyperintensity lesions have volumes of 23mm3 (+/-24.75), a roundness measure of 0.83 (+/-0.08) and an elongation of 7.90 (+/-2.49). The frontal lobe lesions demonstrated significantly more elongated lesions when compared to other areas of the brain.

    OBJECT Symptomatic intracranial atherosclerotic disease (ICAD) has a high risk of recurrent stroke. Genetic polymorphisms in CYP2C19 and CES1 are associated with adverse outcomes in cardiovascular patients, but have not been studied in ICAD. The authors studied CYP2C19 and CES1 single-nucleotide polymorphisms (SNPs) in symptomatic ICAD patients. METHODS Genotype testing for CYP2C19*2, (*)3, (*)8, (*)17 and CES1 G143E was performed on 188 adult symptomatic ICAD patients from 3 medical centers who were medically managed with clopidogrel and aspirin. Testing was performed prospectively at 1 center, and retrospectively from a DNA sample biorepository at 2 centers. Multiple logistic regression and Cox regression analysis were performed to assess the association of these SNPs with the primary endpoint, which was a composite of transient ischemic attack (TIA), stroke, myocardial infarction, or death within 12 months. RESULTS The primary endpoint occurred in 14.9% of the 188 cases. In multiple logistic regression analysis, the presence of the CYP2C19 loss of function (LOF) alleles *2, *3, and *8 in the medically managed patients was associated with lower odds of primary endpoint compared with wild-type homozygotes (odds ratio [OR] 0.13, 95% CI 0.03-0.62, p = 0.0101). Cox regression analysis demonstrated the CYP2C19 LOF carriers had a lower risk for the primary endpoint, with hazard ratio (HR) of 0.27 (95% CI 0.08-0.95), p = 0.041. A sensitivity analysis of a secondary composite endpoint of TIA, stroke, or death demonstrated a significant trend in multiple logistic regression analysis of CYP2C19 variants, with lower odds of secondary endpoint in patients carrying at least 1 LOF allele (*2, *3, *8) than in wild-type homozygotes (OR 0.27, 95% CI 0.06-1.16, p = 0.078). Cox regression analysis demonstrated that the carriers of CYP2C19 LOF alleles had a lower risk forthe secondary composite endpoint (HR 0.22, 95% CI 0.05-1.04, p = 0.056). CONCLUSIONS This is the first study

  19. Dynamics of vitamin D in patients with mild or inactive inflammatory bowel disease and their families

    2013-01-01

    Background 25(OH) vitamin D levels may be low in patients with moderately or severely active inflammatory bowel diseases (IBD: Crohn’s disease and Idiopathic Ulcerative Colitis) but this is less clear in patients with mild or inactive IBD. Furthermore there is limited information of any family influence on 25(OH) vitamin D levels in IBD. As a possible risk factor we hypothesize that vitamin D levels may also be low in families of IBD patients. Objectives To evaluate 25[OH] vitamin D levels in patients with IBD in remission or with mild activity. A second objective is to evaluate whether there are relationships within IBD family units of 25[OH] vitamin D and what are the influences associated with these levels. Methods Participants underwent medical history, physical examination and a 114 item diet questionnaire. Serum 25[OH] vitamin D was measured, using a radioimmunoassay kit, (replete ≥ 75, insufficient 50–74, deficient < 25–50, or severely deficient < 25 nmol/L). Associations between 25[OH] vitamin D and twenty variables were evaluated using univariate regression. Multivariable analysis was also applied and intrafamilial dynamics were assessed. Results 55 patients and 48 controls with their respective families participated (N206). 25[OH] vitamin D levels between patients and controls were similar (71.2 ± 32.8 vs. 68.3 ±26.2 nmol/L). Vitamin D supplements significantly increased intake but correlation with serum 25[OH] vitamin D was significant only during non sunny months among patients. Within family units, patients’ families had mean replete levels (82.3 ± 34.2 nmol/L) and a modest correlation emerged during sunny months between patients and family (r2 =0.209 p = 0.032). These relationships were less robust and non significant in controls and their families. Conclusions In patients with mild or inactive IBD 25[OH] vitamin D levels are less than ideal but are similar to controls. Taken together collectively, the results

    Background The purpose of this study was to confirm the efficacy and safety of twice-daily glycopyrrolate 15.6 µg, a long-acting muscarinic antagonist, in patients with stable, symptomatic, chronic obstructive pulmonary disease (COPD) with moderate-to-severe airflow limitation. Methods The GEM1 study was a 12-week, multicenter, double-blind, parallel-group, placebo-controlled study that randomized patients with stable, symptomatic COPD with moderate-to-severe airflow limitation to twice-daily glycopyrrolate 15.6 µg or placebo (1:1) via the Neohaler® device. The primary objective was to demonstrate superiority of glycopyrrolate versus placebo in terms of forced expiratory volume in 1 second area under the curve between 0 and 12 hours post morning dose at week 12. Other outcomes included additional spirometric end points, transition dyspnea index, St George’s Respiratory Questionnaire, COPD Assessment Test, rescue medication use, and symptoms reported by patients via electronic diary. Safety was also assessed during the study. Results Of the 441 patients randomized (glycopyrrolate, n=222; placebo, n=219), 96% of patients completed the planned treatment phase. Glycopyrrolate demonstrated statistically significant (P<0.001) improvements in lung function versus placebo. Glycopyrrolate showed statistically significant improvement in the transition dyspnea index focal score, St George’s Respiratory Questionnaire total score, COPD Assessment Test score, rescue medication use, and daily total symptom score versus placebo at week 12. Safety was comparable between the treatment groups. Conclusion Significant improvement in lung function, dyspnea, COPD symptoms, health status, and rescue medication use suggests that glycopyrrolate is a safe and effective treatment option as maintenance bronchodilator in patients with stable, symptomatic COPD with moderate-to-severe airflow limitation.

    The levels and duration of physical activity that can be considered as completely safe in patients with sickle cell anaemia (SCA) is unknown. The present study compared the haemorheological and haematological profile, cell density distribution and basic biochemistry between a group of 17 patients with SCA and 21 healthy subjects before and after a 20 min duration submaximal cycling exercise at the same absolute workload. Blood was sampled at rest and 3 min after the end of exercise for measurement of biological parameters. Exercise did not affect the haematocrit and blood viscosity in the two groups. Plasma viscosity was not different between the two groups at rest and similarly increased with exercise. The proportion of intermediary dense cells (with density between 1·11 and 1·12 g/ml) decreased with exercise in the SCA group resulting in an increase in the proportion of red blood cells with a density >1·12 g/ml. No change was observed in the control group. The present study suggests that mild-moderate exercise is not very harmful for SCA patients. The haemorheological and haematological changes were very mild, except for the formation of dense cells but no clinically significant signs of medical complication were present in any of the patients.

    AIM: To compare the clinical efficacy of the second-generation H2RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease (GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis (according to the Los Angeles classification) were randomized to receive lafutidine (10 mg, twice daily) or lansoprazole (30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale (GSRS), and the satisfaction score. RESULTS: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment (P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group (P = 0.0068 and P = 0.0048, respectively). CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD. PMID:27340360

    We present the principal differential characteristics of neuralgia of symptomatic and idiopathic trigeminus. Out of 39 consecutive patients with neuralgia of trigeminus evaluated clinically and with neuroimage study, we find recognizable pathology in 10 (3 arterio-venous malformations, 1 dolichoestasia of basilar artery, 3 tumors, 3 multiple sclerosis). Symptomatic neuralgia occurs in patients with lower average age and is accompanied by atypical symptoms or abnormal neurological signs and is no different from idiopathy as a response to pain from medical treatment. Painful affectation of the trigeminus requires the realization of complementary explorations aiming to dismiss associated neurological pathology. PMID:8059031

    The purpose of this study was to evaluate the physiological basis for sex-differences in exercise-induced dyspnea in patients with mild COPD. We compared operating lung volumes, breathing pattern and dyspnea during incremental cycling in 32 men (FEV(1)=86±10% predicted) and women (FEV(1)=86±12% predicted) with mild COPD and 32 age-matched controls. There were no sex differences in dyspnea in the control group at any work-rate or ventilation (V(E)). Women with COPD had significantly greater dyspnea than men at 60 and 80 W. At 80 W, dyspnea ratings were 5.7±2.3 and 3.3±2.5 Borg units (P<0.05) and the V(E) to maximal ventilatory capacity ratio was 72% and 55% in women and men, respectively (P<0.05). Comparable increases in dynamic hyperinflation were seen in both male and female COPD groups at symptom limitation but women reached tidal volume constraints at a lower work rate and V(E) than men. Superimposing mild COPD on the normal aging effects had greater sensory consequences in women because of their naturally reduced ventilatory reserve. PMID:21524719

    Symptomatic psychosis is one of the central problems in research psychosomatic correlational research. My topic forthis lecture is on the research of symptomatic psychosis, which could be called one of the central problems in the field of clinical psychiatry. It is true that if a person is not physically stable, their "brain" and/or "mind" will not be calm. The opposite is equally true. 1. Are delusions of theft symptomatic psychosis In the elderly, there are some physical disease cases which developed into mental illness. For example, delusions of theft were triggered by physical diseases such as knee osteoarthritis, high blood pressure and glaucoma. I think it is possible to position these patients group as having symptomatic psychosis. 2. "Schizophrenia" is symptomatic psychosis We are thinking that there is a group that the biological material (bilirubin) in body fluid by way of hepatic failure did play a role leading to the expression of schizophrenia. Therefore I propose the following hypothesis: "there is a schizophrenia group that is an expression of a very mild kernicterus". This research started from our experiences having patients who had Gilbert's syndrome which has a high indirect (unconjugated) bilirubin. The patients also had schizophrenia. The psychological symptoms of schizophrenia fluctuated depending on the indirect (unconjugated) bilirubin levels. Also, we clarified that the frequency of patients with schizophrenia coexisting with GS is significantly higher than with other psychiatric disorders. PMID:23367845

    Dyspnea, exercise intolerance, and activity restriction are already apparent in mild chronic obstructive pulmonary disease (COPD). However, patients may not seek medical help until their symptoms become troublesome and persistent and significant respiratory impairment is already present; as a consequence, further sustained physical inactivity may contribute to disease progression. Ventilatory and gas exchange impairment, cardiac dysfunction, and skeletal muscle dysfunction are present to a variable degree in patients with mild COPD, and collectively may contribute to exercise intolerance. As such, there is increasing interest in evaluating exercise tolerance and physical activity in symptomatic patients with COPD who have mild airway obstruction, as defined by spirometry. Simple questionnaires, eg, the modified British Medical Research Council dyspnea scale and the COPD Assessment Test, or exercise tests, eg, the 6-minute or incremental and endurance exercise tests can be used to assess exercise performance and functional status. Pedometers and accelerometers are used to evaluate physical activity, and endurance tests (cycle or treadmill) using constant work rate protocols are used to assess the effects of interventions such as pulmonary rehabilitation. In addition, alternative outcome measurements, such as tests of small airway dysfunction and laboratory-based exercise tests, are used to measure the extent of physiological impairment in individuals with persistent dyspnea. This review describes the mechanisms of exercise limitation in patients with mild COPD and the interventions that can potentially improve exercise tolerance. Also discussed are the benefits of pulmonary rehabilitation and the potential role of pharmacologic treatment in symptomatic patients with mild COPD. PMID:24940054

    This paper describes the design of a prototype telecare system, which allows to provide home care to patients with mild cognitive impairment and thus ensures their permanence in their usual environment. Telecare is oriented towards people who require constant attention due to conditions of advanced age, illness, physical risk or limited capabilities. Telecare offers these people a greater degree of independence. QFD methodology is used to develop electronic devices intended to monitor the environment and physiological state of the user continuously, providing communication between the telecare system and a monitoring center in order to take the most appropriate actions in any abnormal event.

    Traumatic brain injury (TBI) remains a major public health and socio-economic problem, and 70-90% of all TBIs are classified as mild. Mild TBIs and concussions are mostly considered to be non-serious conditions with symptoms subsiding within a few days or weeks. However in 10-15% of patients, the symptoms persist one year after concussion and mostly include headache, fatigue, irritability, and cognitive problems (e.g. memory, concentration). These persisting symptoms negatively influence patient daily activities as postconcussion syndrome (PCS). Second-impact syndrome (SIS) is a very rare but usually fatal condition and occurs when repeated brain injuries lead to a catastrophic diffuse brain swelling. There is no scientific evidence on the incidence and risk of SIS. Chronic traumatic encephalopathy (CTE) is a progressive degenerative disease of the brain found in patients with a history of repetitive brain trauma. CTE presents with behavioural, cognitive, and motor symptoms. The literature to date lacks prospective epidemiological studies of the incidence of CTE. In recent medical literature, there is a description of 110 athletes with postmortem diagnosis of CTE (Tab. 1, Ref. 37). PMID:26810165

    Thalidomide-dexamethasone therapy was given in patients (<61 years) with previously untreated symptomatic multiple myeloma. The aim of this study was to assess the efficacy and toxicity of this combination as first-line therapy, and to determine its effect on stem cell collection and engraftment. During first-line therapy, thalidomide and dexamethasone were administered for 75 days (200 mg/day) and 3 months, respectively. The monthly dose of dexamethasone was 20 mg/m2/day for 4 days, with cycles repeated on days 9 to 12 and 17 to 20 on the first and the third month of therapy. After first-line therapy, a collection of peripheral blood stem cells (PBSC) was performed. Between May 2003 and September 2004, 60 patients were included. On an intent-to-treat basis, the overall response (> or =partial response) rate was 74%, including 24% of patients who obtained a complete remission. Grade 3-4 toxicities consisted of infections (12%), deep-vein thrombosis (3%), constipation (5%), and neuropathy (5%). A total of 58 patients (96%) proceeded to PBSC mobilisation and yielded a median number of 8 x 10(6) CD34+ cells/kg. First-line thalidomide-dexamethasone therapy is effective and relatively well tolerated in young patients with symptomatic multiple myeloma. This combination does not affect PBSC mobilisation.

    Aims Cardiac resynchronization therapy (CRT) with or without a defibrillator reduces morbidity and mortality in selected patients with heart failure (HF) but response can be variable. We sought to identify pre-implantation variables that predict the response to CRT in a meta-analysis using individual patient-data. Methods and results An individual patient meta-analysis of five randomized trials, funded by Medtronic, comparing CRT either with no active device or with a defibrillator was conducted, including the following baseline variables: age, sex, New York Heart Association class, aetiology, QRS morphology, QRS duration, left ventricular ejection fraction (LVEF), and systolic blood pressure. Outcomes were all-cause mortality and first hospitalization for HF or death. Of 3782 patients in sinus rhythm, median (inter-quartile range) age was 66 (58–73) years, QRS duration was 160 (146–176) ms, LVEF was 24 (20–28)%, and 78% had left bundle branch block. A multivariable model suggested that only QRS duration predicted the magnitude of the effect of CRT on outcomes. Further analysis produced estimated hazard ratios for the effect of CRT on all-cause mortality and on the composite of first hospitalization for HF or death that suggested increasing benefit with increasing QRS duration, the 95% confidence bounds excluding 1.0 at ∼140 ms for each endpoint, suggesting a high probability of substantial benefit from CRT when QRS duration exceeds this value. Conclusion QRS duration is a powerful predictor of the effects of CRT on morbidity and mortality in patients with symptomatic HF and left ventricular systolic dysfunction who are in sinus rhythm. QRS morphology did not provide additional information about clinical response. ClinicalTrials.gov numbers NCT00170300, NCT00271154, NCT00251251. PMID:23900696

    A multicenter study of chlorthalidone was performed to determine the relative antihypertensive efficacy and side effects of doses lower than those usually recommended for therapy. After a 4-wk placebo control period 100 patients with mild hypertension were randomly assigned doubleblind to 12.5-, 25-, 50-, or 75-mg regimens of chlorthalidone or to placebo for 12 wk. The groups of patients taking 25, 50, and 75 mg had declines in blood pressure which were not significantly different from each other. Serum potassium decreased in the 50- and 75-mg groups but not significantly in the 25-mg group. We conclude that chlorthalidone, 25 mg daily, was at least as effective for hypertension as 50 and 75 mg with less perturbation of potassium. Use of smaller initial diuretic doses may provide equal efficacy with fewer side effects for many patients. PMID:354839

    Efficacy of actovegin was investigated in the treatment of mild cognitive impairment (MCI) of cerebrovascular genesis. Thirty patients (7 men and 23 women, mean age 71.2 years) received actovegin intramuscularly in dosage 5 ml (200 mg) daily during 4 weeks. Patient's were assessed before and after treatment using CGI and MMSE, verbal association test, scale of frontal dysfunction, clock drawing test, Boston naming test, Mattis dementia scale, test to remember 10 words, the Hamilton depression scale. An improvement was seen in all measures. A positive therapeutic effect, including increased speed of mental processes, reduction of bradiphrenia and memory disorders as well as positive impact on asthenic and depressive symptoms, was identified. Side-effects and adverse events of actovegin were not observed. It is concluded that actovegin could be recommended for elderly patients with early manifestations of cognitive decline. PMID:23994934

    The cognitive impairment of type 2 diabetes patients caused by long-term metabolic disorders has been the current focus of attention. In order to find the related electroencephalogram (EEG) characteristics to the mild cognitive impairment (MCI) of diabetes patients, this study analyses the EEG synchronization with the method of multichannel synchronization analysis--S estimator based on phase synchronization. The results showed that the S estimator values in each frequency band of diabetes patients with MCI were almost lower than that of control group. Especially, the S estimator values decreased significantly in the delta and alpha band, which indicated the EEG synchronization decrease. The MoCA scores and S value had a significant positive correlation in alpha band. PMID:26211240

    Vertigo, was provoked and right torsional up-beat nystagmus was observed in a 47-year-old patient when she was placed into the right Hallpike-Dix test position using infrared goggle technology. The clinical diagnosis was benign paroxysmal positional vertigo (BPPV), specifically right posterior canalithiasis, resulting from a mild traumatic brain injury (TBI) suffered approximately six-months earlier. Previous medical consultations did not include vestibular system examination, and Meclizine was prescribed to suppress her chief complaint of vertigo. Ultimately, the patient was successfully managed by performing two canalith repositioning maneuvers during a single clinical session. The patient reported 100% resolution of symptoms upon reexamination the following day, and the Hallpike-Dix test was negative. Continued symptom resolution was subjectively reported 10 days postintervention via telephone consultation. This case report supports previous publications concerning the presence of BPPV following TBI and the need for inclusion of vestibular system examination during medical consultation. PMID:19826635

    Perfusion deficits in patients with mild traumatic brain injury (TBI) from a military population were characterized by dynamic susceptibility contrast perfusion imaging. Relative cerebral blood flow (rCBF) was calculated by a model-independent deconvolution approach from the tracer concentration curves following a bolus injection of gadolinium diethylenetriaminepentaacetate (Gd-DTPA) using both manually and automatically selected arterial input functions (AIFs). Linear regression analysis of the mean values of rCBF from selected regions of interest showed a very good agreement between the two approaches, with a regression coefficient of R = 0.88 and a slope of 0.88. The Bland-Altman plot also illustrated the good agreement between the two approaches, with a mean difference of 0.6 ± 12.4 mL/100 g/min. Voxelwise analysis of rCBF maps from both approaches demonstrated multiple clusters of decreased perfusion (p < 0.01) in the cerebellum, cuneus, cingulate and temporal gyrus in the group with mild TBI relative to the controls. MRI perfusion deficits in the cerebellum and anterior cingulate also correlated (p < 0.01) with neurocognitive results, including the mean reaction time in the Automated Neuropsychological Assessment Metrics and commission error and detection T-scores in the Continuous Performance Test, as well as neurobehavioral scores in the Post-traumatic Stress Disorder Checklist-Civilian Version. In conclusion, rCBF calculated using AIFs selected from an automated approach demonstrated a good agreement with the corresponding results using manually selected AIFs. Group analysis of patients with mild TBI from a military population demonstrated scattered perfusion deficits, which showed significant correlations with measures of verbal memory, speed of reaction time and self-report of stress symptoms.

    Little is known regarding plaque distribution, composition, and the association with inflammation in type 2 diabetes mellitus (DM2). This study aimed to assess the relationship between coronary plaque subtypes and high-sensitivity C-reactive protein levels. Coronary CTA were performed in 98 symptomatic DM2 patients and 107 non-DM2 patients using a 256-slice CT. The extent and types of plaque as well as luminal narrowing were evaluated. Patients with DM2 were more likely to have significant stenosis (>50%) with calcified plaques in at least one coronary segment (p < 0.01); the prevalence rates of diffuse calcified plaques in the DM2 and non-DM2 groups were 31.6% and 4.7%, respectively (p < 0.01). Plasma hs-CRP levels in DM2 with calcified plaques were higher compared with values obtained for the non-DM2 group (p < 0.01). In conclusion, combination of coronary CTA and hs-CRP might improve risk stratification in symptomatic DM2 patients. PMID:27579325

    Mild cognitive impairment (MCI) was recognized as the prodromal stage of Alzheimer's disease (AD). Recent researches have shown that cognitive and memory decline in AD patients is coupled with losses of small-world attributes. However, few studies pay attention to the characteristics of the whole brain networks in MCI patients. In the present study, we investigated the topological properties of the whole brain networks utilizing graph theoretical approaches in 16 MCI patients, compared with 18 age-matched healthy subjects as a control. Both MCI patients and normal controls showed small-world architectures, with large clustering coefficients and short characteristic path lengths. We detected significantly longer characteristic path length in MCI patients compared with normal controls at the low sparsity. The longer characteristic path lengths in MCI indicated disrupted information processing among distant brain regions. Compared with normal controls, MCI patients showed decreased nodal centrality in the brain areas of the angular gyrus, heschl gyrus, hippocampus and superior parietal gyrus, while increased nodal centrality in the calcarine, inferior occipital gyrus and superior frontal gyrus. These changes in nodal centrality suggested a widespread rewiring in MCI patients, which may be an integrated reflection of reorganization of the brain networks accompanied with the cognitive decline. Our findings may be helpful for further understanding the pathological mechanisms of MCI.

    Previous studies suggest that normal vision pools information from groups of objects in a display to extract statistical summaries (e.g., mean size). Here we explored whether patients with mild, chronic left neglect were able to extract statistical summaries on the right and left sides of space in a typical manner. We tested four patients using a visual search task and varied the mean size of a group of circles within the display. On each trial, a single circle first appeared in the center of the screen (the target). This circle varied in size from trial to trial. Then a multi-item display appeared with circles of various sizes grouped together either on the left or right side of the display. The instructions were to search the circles and determine whether the target was present or not. The circles were always accompanied by a group of task-irrelevant triangles that appeared on the opposite side of the display. On half the trials, the mean size of the circles was the size of the target. On the other half the mean size was different from the target. The patients were not told that this was the case, and no explicit report of the statistics was required. The results showed that when the targets were absent patients produced more false alarms to the mean than non-mean size when the circles were on the left (neglected) side of the display. This finding demonstrates that statistical information was implicitly extracted from the left group of circles. However, summary statistics on the right side were not limited to the circles. Rather it appears that participants pooled the distractors with the target circles, yielding a skewed statistical summary on the right side. These findings are discussed as they relate to statistical summary processing, visual search and segregation of right and left items in patients with mild, chronic unilateral neglect. PMID:23060771

    Third-generation EGFR TKI has been approved in the US and EU for the treatment of EGFR mutant T790M+ NSCLC patients that are resistant to first- or second generation EGFR TKIs. Here we report a patient who developed resistance to osimertinib after a confirmed partial response for 9 months. Pre-osimertinib and post-osimertinib tumor biopsy revealed the emergence of high level of MET amplification (30 copies) post osimertinib treatment. Patient was treated with single agent crizotinib, a known MET inhibitor, with transient symptomatic benefit. MET amplification is one potential resistance mechanism to osimertinib and combination of osimertinib and a MET inhibitor should be investigated post-osimertinib progression in EGFR mutant T790M+ NSCLC patients whose harbored acquired MET amplification.

    Symptomatic animal models have clinical features consistent with human disorders and are often used to identify the anatomical and physiological processes involved in the expression of symptoms and to experimentally demonstrate causality where it would be infeasible in the patient population. Rodent and primate models of dystonia have identified basal ganglia abnormalities, including alterations in striatal GABAergic and dopaminergic transmission. Symptomatic animal models have also established the critical role of the cerebellum in dystonia, particularly abnormal glutamate signaling and aberrant Purkinje cell activity. Further, experiments suggest that the basal ganglia and cerebellum are nodes in an integrated network that is dysfunctional in dystonia. The knowledge gained from experiments in symptomatic animal models may serve as the foundation for the development of novel therapeutic interventions to treat dystonia. PMID:23893454

    This letter to the editor describes the case of a 42 year old man with mild traumatic brain injury and multiple neuropsychiatric symptoms which persisted for a few years after the injury. Initial CT scans and MRI scans of the brain showed no signs of atrophy. Brain volume was measured using NeuroQuant®, an FDA-approved, commercially available software method. Volumetric cross-sectional (one point in time) analysis also showed no atrophy. However, volumetric longitudinal (two points in time) analysis showed progressive atrophy in several brain regions. This case illustrated in a single patient the principle discovered in multiple previous group studies, namely that the longitudinal design is more powerful than the cross-sectional design for finding atrophy in patients with traumatic brain injury.

Vascular cognitive impairment is not limited to only dementia, representing a heterogeneous group both in pathogenic and clinical terms. The article dwells upon new principles of vascular cognitive impairment's classification and the review of their possible therapeutic correction that was conducted. The article includes the results of the 12-week open therapeutic (randomized with the control group) study of efficiency and safety of vitrum memory for patients with mild vascular cognitive impairment. It is shown that the therapy significantly improved the state of neurodynamic and regulatory functions of the patients with I--II stage dyscirculatory encephalopathy. PMID:23739499

    Psoriasis is a chronic inflammatory skin disease with a high social and psychological impact on the quality of life of patients. Tomesa balneophototherapy is based on bathing in a magnesium-rich salt solution combined with exposure to narrowband ultraviolet B phototherapy. We conducted a retrospective clinical trial on 174 patients affected by mild to severe psoriasis undergoing Tomesa balneophototherapy. The basal course consisted of three to five sessions per week for a total of 30 sessions. Subsequently, patients could continue with a maintenance course of one session per week for a total of 30 sessions. We recorded a significant reduction of the mean Psoriasis Area and Severity Index (PASI) index with an achievement of at least PASI 75 in 52.1% of the 119 patients who completed the basal course and an improvement of the 'quality of life' of patients. The good efficacy obtained by this treatment, and the psychological impact on the quality of life of patients, demonstrated that Tomesa balneophototherapy could be a good option for the treatment of a chronic disease associated with psychological distress, like psoriasis.

    Recent findings suggest that Alzheimer's disease (AD) is a disconnection syndrome characterized by abnormalities in large-scale networks. However, the alterations that occur in network topology during the prodromal stages of AD, particularly in patients with stable mild cognitive impairment (MCI) and those that show a slow or faster progression to dementia, are still poorly understood. In this study, we used graph theory to assess the organization of structural MRI networks in stable MCI (sMCI) subjects, late MCI converters (lMCIc), early MCI converters (eMCIc), and AD patients from 2 large multicenter cohorts: ADNI and AddNeuroMed. Our findings showed an abnormal global network organization in all patient groups, as reflected by an increased path length, reduced transitivity, and increased modularity compared with controls. In addition, lMCIc, eMCIc, and AD patients showed a decreased path length and mean clustering compared with the sMCI group. At the local level, there were nodal clustering decreases mostly in AD patients, while the nodal closeness centrality detected abnormalities across all patient groups, showing overlapping changes in the hippocampi and amygdala and nonoverlapping changes in parietal, entorhinal, and orbitofrontal regions. These findings suggest that the prodromal and clinical stages of AD are associated with an abnormal network topology. PMID:27178195

    Background Our objective was to study the effect of trauma on texture features in cerebral tissue in mild traumatic brain injury (MTBI). Our hypothesis was that a mild trauma may cause microstructural changes, which are not necessarily perceptible by visual inspection but could be detected with texture analysis (TA). Methods We imaged 42 MTBI patients by using 1.5 T MRI within three weeks of onset of trauma. TA was performed on the area of mesencephalon, cerebral white matter at the levels of mesencephalon, corona radiata and centrum semiovale and in different segments of corpus callosum (CC) which have been found to be sensitive to damage. The same procedure was carried out on a control group of ten healthy volunteers. Patients' TA data was compared with the TA results of the control group comparing the amount of statistically significantly differing TA parameters between the left and right sides of the cerebral tissue and comparing the most discriminative parameters. Results There were statistically significant differences especially in several co-occurrence and run-length matrix based parameters between left and right side in the area of mesencephalon, in cerebral white matter at the level of corona radiata and in the segments of CC in patients. Considerably less difference was observed in the healthy controls. Conclusions TA revealed significant changes in texture parameters of cerebral tissue between hemispheres and CC segments in TBI patients. TA may serve as a novel additional tool for detecting the conventionally invisible changes in cerebral tissue in MTBI and help the clinicians to make an early diagnosis. PMID:20462439

    We used continuous electroencephalography-functional magnetic resonance imaging (EEG-fMRI) to identify the linkage between the "epileptogenic" and the "irritative" area in a patient with symptomatic epilepsy (cavernoma, previously diagnosed and surgically treated), i.e. a patient with a well known "epileptogenic area", and to increase the possibility of a non invasive pre-surgical evaluation of drug-resistant epilepsies. A compatible MRI system was used (EEG with 29 scalp electrodes and two electrodes for ECG and EMG) and signals were recorded with a 1.5 Tesla MRI scanner. After the recording session and MRI artifact removal, EEG data were analyzed offline and used as paradigms in fMRI study. Activation (EEG sequences with interictal slow-spiked-wave activity) and rest (sequences of normal EEG) conditions were compared to identify the potential resulting focal increase in BOLD signal and to consider if this is spatially linked to the interictal focus used as a paradigm and to the lesion. We noted an increase in the BOLD signal in the left neocortical temporal region, laterally and posteriorly to the poro-encephalic cavity (residual of cavernoma previously removed), that is around the "epileptogenic area". In our study "epileptogenic" and "irritative" areas were connected with each other. Combined EEG-fMRI may become routine in clinical practice for a better identification of an irritative and lesional focus in patients with symptomatic drug-resistant epilepsy. PMID:24256824

    Purpose The purpose of this study was to compare the diagnostic performance of SPECT/CT and MRI in patients with ankle and foot pain, with regard to the lesion types. Materials and Methods Fifty consecutive patients with ankle and foot pain, who underwent 99mTc-MDP SPECT/CT and MRI, were retrospectively enrolled in this study. Symptomatic lesions were determined based on clinical examination and response to treatment. On MRI and SPECT/CT, detected lesions were classified as bone, ligament/tendon, and joint lesions. Uptake on SPECT/CT was assessed using a 4-grade system. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of SPECT/CT and MRI were evaluated in all detected lesions and each lesion type. Diagnostic value of uptake grade was analyzed using receiver-operating characteristics (ROC) curve analysis, and diagnostic performance was compared using Chi-square or McNemar tests. Results In overall lesions, the sensitivity, PPV and NPV of SPECT/CT for symptomatic lesions were 93%, 56%, 91%, and they were 98%, 48%, 95% for MRI. There was no significant difference between SPECT/CT and MRI. However, the specificity of SPECT/CT was significantly higher than that of MRI (48% versus 24%, P = 0.016). Uptake grade on SPECT/CT was significantly higher in symptomatic lesions (P < 0.001), and its area under curve on ROC analysis was 0.787. In the analysis of each lesion type, the specificity of SPECT/CT was poor in joint lesions compared with other lesion types and MRI (P < 0.001, respectively). MRI exhibited lower specificity than SPECT/CT in bone lesions (P = 0.004) and ligament/tendon lesions (P < 0.001). Conclusions SPECT/CT has MRI-comparable diagnostic performance for symptomatic lesions in ankle and foot pain patients. SPECT/CT and MRI exhibit different diagnostic specificity in different lesion types. SPECT/CT may be used as a complementary imaging method to MRI for enhancing diagnostic specificity. PMID:25668182

    Amnestic mild cognitive impairment (MCI) has been conceptualized as a transitional stage between healthy aging and Alzheimer’s disease. Thus, understanding emotional face recognition deficit in patients with amnestic MCI could be useful in determining progression of amnestic MCI. The purpose of this study was to investigate the features of emotional face processing in amnestic MCI by using event-related potentials (ERPs). Patients with amnestic MCI and healthy controls performed a face recognition task, giving old/new responses to previously studied and novel faces with different emotional messages as the stimulus material. Using the learning-recognition paradigm, the experiments were divided into two steps, ie, a learning phase and a test phase. ERPs were analyzed on electroencephalographic recordings. The behavior data indicated high emotion classification accuracy for patients with amnestic MCI and for healthy controls. The mean percentage of correct classifications was 81.19% for patients with amnestic MCI and 96.46% for controls. Our ERP data suggest that patients with amnestic MCI were still be able to undertake personalizing processing for negative faces, but not for neutral or positive faces, in the early frontal processing stage. In the early time window, no differences in frontal old/new effect were found between patients with amnestic MCI and normal controls. However, in the late time window, the three types of stimuli did not elicit any old/new parietal effects in patients with amnestic MCI, suggesting their recollection was impaired. This impairment may be closely associated with amnestic MCI disease. We conclude from our data that face recognition processing and emotional memory is impaired in patients with amnestic MCI. Such damage mainly occurred in the early coding stages. In addition, we found that patients with amnestic MCI had difficulty in post-processing of positive and neutral facial emotions. PMID:26347065

    In the present work we analyzed the effect of contextual word predictability on the eye movement behavior of patients with mild Alzheimer disease (AD) compared to age-matched controls, by using the eyetracking technique and lineal mixed models. Twenty AD patients and 40 age-matched controls participated in the study. We first evaluated gaze duration during reading low and highly predictable sentences. AD patients showed an increase in gaze duration, compared to controls, both in sentences of low or high predictability. In controls, highly predictable sentences led to shorter gaze durations; by contrary, AD patients showed similar gaze durations in both types of sentences. Similarly, gaze duration in controls was affected by the cloze predictability of word N and N+1, whereas it was the same in AD patients. In contrast, the effects of word frequency and word length were similar in controls and AD patients. Our results imply that contextual-word predictability, whose processing is proposed to require memory retrieval, facilitated reading behavior in healthy subjects, but this facilitation was lost in early AD patients. This loss might reveal impairments in brain areas such as those corresponding to working memory, memory retrieval, and semantic memory functions that are already present at early stages of AD. In contrast, word frequency and length processing might require less complex mechanisms, which were still retained by AD patients. To the best of our knowledge, this is the first study measuring how patients with early AD process well-defined words embedded in sentences of high and low predictability. Evaluation of the resulting changes in eye movement behavior might provide a useful tool for a more precise early diagnosis of AD. PMID:25080188

    Learning and memory deficits typify patients with mild cognitive impairment (MCI) and are generally attributed to medial temporal lobe dysfunction. Although the hippocampus is perhaps the most commonly studied neuroanatomical structure in these patients, there have been few attempts to identify rehabilitative interventions that facilitate its functioning. Here, we present results from a randomized, controlled, single-blind study in which patients with MCI and healthy elderly controls (HEC) were randomized to either 3 sessions of mnemonic strategy training (MS) or a matched-exposure control group (XP). All participants underwent pre- and post-training fMRI scanning as they encoded and retrieved object-location associations. For the current report, fMRI analyses were restricted to the hippocampus, as defined anatomically. Before training, MCI patients showed reduced hippocampal activity during both encoding and retrieval, relative to HEC. Following training, the MCI MS group demonstrated increased activity during both encoding and retrieval. There were significant differences between the MCI MS and MCI XP groups during retrieval, especially within the right hippocampus. Thus, MS facilitated hippocampal functioning in a partially restorative manner. We conclude that cognitive rehabilitation techniques may help mitigate hippocampal dysfunction in MCI patients.

    This internal representation of movement of part(s) of the body is involved during Implicit Motor Imagery tasks (IMI); the same representations are employed in the laterality judgment task. Few studies have looked at the consequences of aging, Alzheimer's disease (AD) and mild cognitive impairment (MCI) on the processes of motor preparation but none showed evidence of an alteration of action representation in patient with amnestic MCI. In the present study, the IMI task was used to assess the action representation abilities in MCI patients and healthy counterparts. A total of 24 elderly participants aged between 65 and 90 years old (12 women, 73.4 ± 6 years, mean ± S.D.) were recruited: 12 patients with MCI (MCI group) and 12 healthy aged adults (HAA group). The results showed that MCI patients have significantly a greater response time (RT) than HAA subjects only in IMI task and more precisely when performing their mental rotation at the challenging conditions. Furthermore, the IMI task related to the non-dominant hand induced a significant increase of RT only in MCI subjects. At the light of these results, we assume that MCI patients are able to engage themselves in IMI processes, still showing a compelling impairment of this mental ability across its complexity.

    Although the pathophysiology of essential tremor (ET), one of the most common movement disorders, is not fully understood, evidence increasingly points to cerebellar involvement. To confirm this connection, we assessed the everyday hand and finger movements of patients with ET, as these movements are known to be affected in cerebellar diseases. In 26 mildly affected patients with ET (compared to age- and gender-matched controls), kinematic and finger force parameters were assessed in a precision grip. In a second task, independent finger movements were recorded. The active finger had to press and release against a force-sensitive keypad while the other fingers stayed inactive. Finally, control of grip force to movement-induced, self-generated load changes was studied. Transport and shaping components during prehension were significantly impaired in patients with ET compared to controls. No significant group differences were observed in independent finger movements and grip force adjustments to self-generated load force changes. However, in the latter two tasks, more severely affected ET patients performed worse than less affected. Although observed deficits in hand and finger movement tasks were small, they are consistent with cerebellar dysfunction in ET. Findings need to be confirmed in future studies examining more severely affected ET patients. PMID:26310449

A total of 24 elderly participants aged between 65 and 90 years old (12 women, 73.4 ± 6 years, mean ± S.D.) were recruited: 12 patients with MCI (MCI group) and 12 healthy aged adults (HAA group). The results showed that MCI patients have significantly a greater response time (RT) than HAA subjects only in IMI task and more precisely when performing their mental rotation at the challenging conditions. Furthermore, the IMI task related to the non-dominant hand induced a significant increase of RT only in MCI subjects. At the light of these results, we assume that MCI patients are able to engage themselves in IMI processes, still showing a compelling impairment of this mental ability across its complexity.

    It is well known that flow patterns at the anastomosis of coronary artery bypass graft (CABG) are complex and may affect the long-term patency. Various attempts at optimal designs of anastomosis have not improved long-term patency. Here, we hypothesize that mild anastomotic stenosis (area stenosis of about 40-60%) may be adaptive to enhance the hemodynamic conditions, which may contribute to slower progression of atherosclerosis. We further hypothesize that proximal/distal sites to the stenosis have converse changes that may be a risk factor for the diffuse expansion of atherosclerosis from the site of stenosis. Twelve (12) patient-specific models with various stenotic degrees were extracted from computed tomography images using a validated segmentation software package. A 3-D finite element model was used to compute flow patterns including wall shear stress (WSS) and its spatial and temporal gradients (WSS gradient, WSSG, and oscillatory shear index, OSI). The flow simulations showed that mild anastomotic stenosis significantly increased WSS (>15 dynes · cm(-2)) and decreased OSI (<0.02) to result in a more uniform distribution of hemodynamic parameters inside anastomosis albeit proximal/distal sites to the stenosis have a decrease of WSS (<4 dynes · cm(-2)). These findings have significant implications for graft adaptation and long-term patency. PMID:24058488

    Effective treatment of diabetic sensorimotor polyneuropathy remains a challenge. To assess the efficacy and safety of α-lipoic acid (ALA) over 20 weeks, we conducted a multicenter randomized withdrawal open-label study, in which 45 patients with type 2 diabetes and symptomatic polyneuropathy were initially treated with ALA (600 mg tid) for 4 weeks (phase 1). Subsequently, responders were randomized to receive ALA (600 mg qd; n = 16) or to ALA withdrawal (n = 17) for 16 weeks (phase 2). During phase 1, the Total Symptom Score (TSS) decreased from 8.9 ± 1.8 points to 3.46 ± 2.0 points. During phase 2, TSS improved from 3.7 ± 1.9 points to 2.5 ± 2.5 points in the ALA treated group (p < 0.05) and remained unchanged in the ALA withdrawal group. The use of analgesic rescue medication was higher in the ALA withdrawal group than ALA treated group (p < 0.05). In conclusion, in type 2 diabetic patients with symptomatic polyneuropathy who responded to initial 4-week high-dose (600 mg tid) administration of ALA, subsequent treatment with ALA (600 mg qd) over 16 weeks improved neuropathic symptoms, whereas ALA withdrawal was associated with a higher use of rescue analgesic drugs.

    ASTERIA I was a 40-week, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of subcutaneous omalizumab as add-on therapy for 24 weeks in patients with chronic idiopathic urticaria/spontaneous urticaria (CIU/CSU) who remained symptomatic despite H1 antihistamine treatment at licensed doses. Patients aged 12–75 years with CIU/CSU who remained symptomatic despite treatment with approved doses of H1 antihistamines were randomized (1:1:1:1) in a double-blind manner to subcutaneous omalizumab 75 mg, 150 mg, or 300 mg or placebo every 4 weeks for 24 weeks followed by 16 weeks of follow-up. The primary end point was change from baseline in weekly itch severity score (ISS) at week 12. Among randomized patients (N=319: placebo n=80, omalizumab 75 mg n=78, 150 mg n=80, 300 mg n=81), 262 (82.1%) completed the study. Compared with placebo (n=80), mean weekly ISS was reduced from baseline to week 12 by an additional 2.96 points (95% confidence interval (CI): −4.71 to −1.21; P=0.0010), 2.95 points (95% CI: −4.72 to −1.18; P=0.0012), and 5.80 points (95% CI: −7.49 to −4.10; P<0.0001) in the omalizumab 75-mg (n=77), 150-mg (n=80), and 300-mg groups (n=81), respectively. The omalizumab 300-mg group met all nine secondary end points, including a significant decrease in the duration of time to reach minimally important difference response (⩾5-point decrease) in weekly ISS (P<0.0001) and higher percentages of patients with well-controlled symptoms (urticaria activity score over 7 days (UAS7) ⩽6: 51.9% vs. 11.3% P<0.0001) and complete response (UAS7=0: 35.8% vs. 8.8% P<0.0001) versus placebo. During the 24-week treatment period, 2 (2.9%), 3 (3.4%), 0, and 4 (5.0%) patients in the omalizumab 75-mg, 150-mg, 300-mg, and placebo groups, respectively, experienced a serious adverse event. Omalizumab 300 mg administered subcutaneously every 4 weeks reduced weekly ISS and other symptom scores versus placebo in CIU/CSU patients

    Small asymptomatic cysts of the pineal gland represent a common incidental finding in adults undergoing computerized tomography or magnetic resonance (MR) imaging or at postmortem examination. In contrast, large symptomatic pineal cysts are rare, being limited to individual case reports or small series. The authors have reviewed 24 cases of large pineal cysts. The mean patient age at presentation was 28.7 years (range 15 to 46 years); 18 were female and six male. Presenting features in 20 symptomatic cases included: headache in 19; nausea and/or vomiting in seven; papilledema in five; visual disturbances in five (diplopia in three, "blurred vision" in two, and unilateral partial oculomotor nerve palsy in one); Parinaud's syndrome in two; hemiparesis in one; hemisensory aberration in one; and seizures in one. Four lesions were discovered incidentally. Magnetic resonance imaging typically demonstrated a 0.8- to 3.0-cm diameter mass (mean 1.7 cm) with homogeneous decreased signal intensity on T1-weighted images, increased signal intensity on T2-weighted images, and a distinct margin. Hydrocephalus was present in eight cases. The cysts were surgically excised via an infratentorial/supracerebellar approach (23 cases) or stereotactically biopsied (one case). Histological examination revealed a cyst wall 0.5 to 2.0 mm thick comprised of three layers: an outer fibrous layer, a middle layer of pineal parenchymal cells with variable calcification, and an inner layer of hypocellular glial tissue often exhibiting Rosenthal fibers and/or granular bodies. Evidence of prior hemorrhage, mild astrocytic degenerative atypia, and disorganization of pineal parenchyma were often present. Postoperative follow-up review in all 24 cases (range 3 months to 10 years) revealed no complications in 21, mild ocular movement deficit in one, gradually resolving Parinaud's syndrome in one, and radiographic evidence of a postoperative venous infarct of the superior cerebellum with ataxia of 1 week

    It is well recognized that mitochondrial dysfunction contributes to neurodegeneration occurring in Alzheimer's disease (AD). However, evidences of mitochondrial defects in AD peripheral cells are still inconclusive. Here, some mitochondrial-encoded and nuclear-encoded proteins, involved in maintaining the correct mitochondria machine, were investigated in terms of protein expression and enzymatic activity in peripheral blood mononuclear cells (PBMCs) isolated from AD and Mild Cognitive Impairment (MCI) patients and healthy subjects. In addition mitochondrial DNA copy number was measured by real time PCR. We found some differences and some similarities between AD and MCI patients when compared with healthy subjects. For example, cytochrome C and cytochrome B were decreased in AD, while MCI showed only a statistical reduction of cytochrome C. On the other hand, both AD and MCI blood cells exhibited highly nitrated MnSOD, index of a prooxidant environment inside the mitochondria. TFAM, a regulator of mitochondrial genome replication and transcription, was decreased in both AD and MCI patients' blood cells. Moreover also the mitochondrial DNA amount was reduced in PBMCs from both patient groups. In conclusion these data confirmed peripheral mitochondria impairment in AD and demonstrated that TFAM and mtDNA amount reduction could be two features of early events occurring in AD pathogenesis.

    A variety of studies demonstrated that some forms of memory for music are spared in dementia, but only few studies have investigated patients with early stages of dementia. In this pilot-study we tested working memory for music in patients with mild cognitive impairment (MCI) and early stage Alzheimer's disease (AD) with a newly created test. The test probed working memory using 7 gradually elongated tone-lines and 6 chords which were each followed by 3 similar items and 1 identical item. The participants of the study, namely 10 patients with MCI, 10 patients with early stage AD and 23 healthy subjects were instructed to select the identical tone-line or chord. Subjects with MCI and early AD showed significantly reduced performance than controls in most of the presented tasks. In recognizing chords MCI- participants surprisingly showed an unimpaired performance. The gradual increase of the impairment during the preclinical phase of AD seems to spare this special ability in MCI. PMID:23329298

  5. Initial clinical experience with a novel vertebral augmentation system for treatment of symptomatic vertebral compression fractures: A case series of 26 consecutive patients

    Background Minimally invasive vertebral augmentation procedures are widely used to treat vertebral compression fractures although procedural polymethylmethacrylate cement leakage remains common. We report herein our initial experience with a novel vertebral augmentation technique designed to treat symptomatic vertebral osteoporotic fractures and osteolytic metastases with minimal cement extravasation. Methods Forty-two vertebral fractures were identified in 26 consecutive patients (mean age 74 ± 9 years). All patients were treated with a novel percutaneous vertebral augmentation device (Kiva® VCF Treatment System, Benvenue Medical, Santa Clara, CA, USA). Indications for surgery included recent (≤ 3 months) symptomatic osteoporotic vertebral fracture (n = 34) and pathologic vertebral fractures (e.g. metabolic bone disease, myeloma, metastasis) (n = 8) located between T10 and S1. Patient outcomes were evaluated pre-treatment and at 2- and 6-month follow-up visits. Postoperative cement extravasation was assessed with computed tomography. Patient-reported back pain was quantified using an 11-point numeric scale. Back-specific functional disability was self-reported with the Oswestry Disability Index on a 0 to 100% scale. Results No cases of intraoperative hypotension, respiratory disturbance, neurological deterioration, infection, or death were observed. There were 2 (4.8%) levels where anterior cement leakage was visible radiographically in patients with osteolyses. No intracanal leakage was observed. Back pain scores improved 71% (p < 0.001) from pre-treatment to the 6-month follow-up. Back function improved 56% from baseline to 6 months (p < 0.001). Conclusions The initial clinical experience with the Kiva® System demonstrated significant improvements in back pain and function with minimal and clinically insignificant procedural cement leakage.

    Our objective was to determine the probability threshold for recurrent symptoms at which elective cholecystectomy compared to observation in older patients with symptomatic cholelithiasis is the more effective and cost-effective option. We built a decision model of elective cholecystectomy versus observation in patients >65 presenting with initial episodes of symptomatic cholelithiasis that did not require initial hospitalization or cholecystectomy. Probabilities for subsequent hospitalization, emergency cholecystectomy, and perioperative complications were based on previously published probabilities from a 5 % national sample of Medicare patients. Costs were estimated from Medicare reimbursements and from the Healthcare Cost and Utilization Project. Utilities (quality-adjusted life years, QALYs) were obtained from established literature estimates. Elective cholecystectomy compared to observation in all patients was associated with lower effectiveness (-0.10 QALYs) and had an increased cost of $3,422.83 per patient at 2-year follow-up. Elective cholecystectomy became the more effective option when the likelihood for continued symptoms exceeded 45.3 %. Elective cholecystectomy was both more effective and less costly when the probability for continued symptoms exceeded 82.7 %. An individualized shared decision-making strategy based on these data can increase elective cholecystectomy rates in patients at high risk for recurrent symptoms and minimize unnecessary cholecystectomy for patients unlikely to benefit.

    Metastatic castrate-resistant prostate cancer (CRPC) refers to the disease state in which metastatic prostate cancer fails to respond to androgen deprivation therapy (ADT). This can be manifest as a rising PSA, increase in radiographically measurable disease, or progression of clinical disease. Roughly 90 % of men with metastatic prostate cancer have bone metastases, which is a predictor of both morbidity and mortality. Historically, treatment has been palliative, consisting of external beam radiation therapy (EBRT) and pharmacological analgesics for pain control and osteoclast inhibitors, such as bisphosphonates and denosumab to mitigate skeletal-related events. Older radiopharmaceuticals, such as Strontium-89 and Samarium-153, are Beta-emitting agents that were found to provide palliation but were without survival benefit and carried high risks of myelosuppression. Radium-223 is an Alpha-emitting radiopharmaceutical that has demonstrated a significant overall survival benefit in men with metastatic CRPC, delay to symptomatic skeletal events (SSEs), and improvement in pain control, with a favorable toxicity profile compared with placebo. Unlike EBRT, Radium-223 has systemic uptake, with the potential to address several bone metastases concurrently and provides overall survival benefit. It is a simple administration with minimal complexity and shielding requirements in experienced hands. EBRT appears to provide a more rapid and dramatic palliative benefit to any given lesion. Because Radium-223 has limited myelosuppression, the two can be thoughtfully integrated, along with multiple agents, for the treatment of men with CRPC with symptomatic bone metastases. Given its excellent safety profile, there is interest and anecdotal safety combining Radium-223 with therapies, such as abiraterone and enzalutamide. Formal recommendations regarding combination therapies will require clinical trials. The use of Alpha-emitting radiopharmaceuticals in castrate-sensitive disease

    Systematic capture of the patient perspective can inform the development of new cancer therapies. Patient-reported outcomes (PROs) are commonly included in cancer clinical trials; however, there is heterogeneity in the constructs, measures, and analytic approaches that have been used making these endpoints challenging to interpret. There is renewed effort to identify rigorous methods to obtain high-quality and informative PRO data from cancer clinical trials. In this setting, PROs are used to address specific research objectives, and an important objective that spans the product development life cycle is the assessment of safety and tolerability. The U.S. Food and Drug Administration's (FDA) Office of Hematology and Oncology Products (OHOP) has identified symptomatic adverse events (AEs) as a central PRO concept, and a systematic assessment of patient-reported symptomatic AEs can provide data to complement clinician reporting. The National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) is being evaluated by multiple stakeholders, including the FDA, and is considered a promising tool to provide a standard yet flexible method to assess symptomatic AEs from the patient perspective. In this article, we briefly review the FDA OHOP's perspective on PROs in cancer trials submitted to the FDA and focus on the assessment of symptomatic AEs using PRO-CTCAE. We conclude by discussing further work that must be done to broaden the use of PRO-CTCAE as a method to provide patient-centered data that can complement existing safety and tolerability assessments across cancer clinical trials.

    Mild traumatic brain injury (mTBI) is often occult to conventional imaging techniques. However, there is growing evidence that mTBI patients who lack evidence of structural intracranial injury may develop post-concussive syndrome (PCS). We investigated longitudinal alterations in resting state functional connectivity (rs-FC) in brain networks in a population of 28 patients compared to 28 matched control participants. Rs-FC and cerebral blood flow (CBF) within the nodes of the Default Mode Network (DMN) and Task Positive Network (TPN) were assessed at three time points including acute, sub-acute, and chronic stages following mTBI. Participants received the Automated Neuropsychological Assessment Metrics (ANAM) to assess cognitive performance. Main findings indicate that despite normalized cognitive performance, chronic mTBI patients demonstrate increased rs-FC between the DMN and regions associated with the salience network (SN) and TPN compared to the control populations, as well as reduced strength of rs-FC within the DMN at the acute stage of injury. In addition, chronic mTBI patients demonstrate an imbalance in the ratio of CBF between nodes of the DMN and TPN. Furthermore, preliminary exploratory analysis suggests that compared to those without chronic PCS, patients with chronic PCS reveal an imbalance in the ratio of CBF between the DMN nodes and TPN nodes across multiple stages of recovery. Findings suggest that the altered network perfusion with the associated changes in rs-FC may be a possible predictor of which mTBI patients will develop chronic PCS. PMID:26241476

    Summary Mild cognitive impairment (MCI) entails a high risk of developing Alzheimer’s dementia. In MCI patients gait impairment, which increases the risk of falls and institutionalization, is an early motor sign. A dual-task (DT) paradigm might improve the observation of this phenomenon. The aim of this study was to investigate motor-cognitive interference in a sample of MCI patients and a group of matched healthy controls submitted to DT conditions. To this end, three different cognitive tasks were used: counting backwards, short story recall and a phonemic fluency task. Overall, the patients, compared with the healthy participants, performed worse on the cognitive tasks and showed some degree of gait impairment. In the DT conditions, both groups showed significant gait disruption independently of the concomitant cognitive task. As regards cognitive performance, counting backwards worsened during dual tasking, while short story recall improved in both groups. Overall, our results suggest that the use of a DT paradigm does not improve the early detection of MCI. Our findings of enhanced story recall during walking might have interesting implications for rehabilitation of memory function. PMID:26214028

    Objectives The aim of this study was to investigate pathological mechanisms underlying brain tissue alterations in mild cognitive impairment (MCI) using multi-contrast 3 T magnetic resonance imaging (MRI). Methods Forty-two MCI patients and 77 healthy controls (HC) underwent T1/T2* relaxometry as well as Magnetization Transfer (MT) MRI. Between-groups comparisons in MRI metrics were performed using permutation-based tests. Using MRI data, a generalized linear model (GLM) was computed to predict clinical performance and a support-vector machine (SVM) classification was used to classify MCI and HC subjects. Results Multi-parametric MRI data showed microstructural brain alterations in MCI patients vs HC that might be interpreted as: (i) a broad loss of myelin/cellular proteins and tissue microstructure in the hippocampus (p ≤ 0.01) and global white matter (p < 0.05); and (ii) iron accumulation in the pallidus nucleus (p ≤ 0.05). MRI metrics accurately predicted memory and executive performances in patients (p ≤ 0.005). SVM classification reached an accuracy of 75% to separate MCI and HC, and performed best using both volumes and T1/T2*/MT metrics. Conclusion Multi-contrast MRI appears to be a promising approach to infer pathophysiological mechanisms leading to brain tissue alterations in MCI. Likewise, parametric MRI data provide powerful correlates of cognitive deficits and improve automatic disease classification based on morphometric features. PMID:26236628

Methods After MTBI, perfusion MR imaging technique (3D-PCASL) measures the CBF of MTBI patients (n = 23) within 1 month and that of normal controls (n = 22) to determine the quantity and location of perfusion defect. The correlation between CBF abnormalities and cognitive deficits was elucidated by combining the results of the neuropsychological tests of the patients. Result We observed a substantial reduction in CBF in the bilateral frontal and left occipital cortex as compared with the normal persons. In addition, there were correlation between post concussive symptoms (including dizziness and simulator sickness) and CBF in the hypoperfused areas. The more severe symptom was correlated with higher CBF in bilateral frontal and left occipital lobes. Conclusion First, this study determined that despite no significant abnormality detected on conventional CT and MRI studies, hypoperfusion was observed in MTBI group using 3D-PCASL technique in subacute stage, which suggested that this approach may increase sensitivity to MTBI. Second, the correlation between CBF and the severity of post concussive symptoms suggested that changes in cerebral hemodynamics may play a role in pathophysiology underlies the symptoms.

    Abstract We report on patients with post-traumatic fatigue and hypersomnia who showed injury of the lower portion of the ascending reticular activating system (ARAS) between the pontine reticular formation (RF) and the intralaminar thalamic nucleus (ILN) following mild traumatic brain injury (TBI), using diffusion tensor tractography (DTT). Two patients with mild TBI resulting from a car accident were enrolled in this study. Patient 1 was a 51-year-old woman showed abnormalities as 6.9 (cut off: 3.7 points) and 18 (cut off: 10) on the Fatigue Severity Scale and the Epworth Sleepiness Scale at 11 months after onset. Patient 2 was a 64-year-old woman who revealed abnormalities on the Fatigue Severity Scale and the Epworth Sleepiness Scale with 6.8 and 19 at 3 months after onset. In both patients, the upper ARAS in which the neural connectivity of the ILN to the cerebral cortex did not show significant abnormalities. However, we observed the narrowing of the left dorsal lower ARAS between the pontine RF and the ILN in both patients and the tearing (patient 1) and narrowing (patient 2) of the left ventral lower ARAS between the pontine RF and the hypothalamus. Injuries of the dorsal and ventral lower ARAS were demonstrated in patients with fatigue and hypersomnia following mild TBI. We believe that these injuries of the ARAS might be a pathogenetic mechanism of fatigue and hypersomnia in patients with TBI. PMID:26871783

    Objective To investigate the incidence of corpus callosum injury (CCI) in patients with mild traumatic brain injury (TBI) using brain MRI. We also performed a review of the clinical characteristics associated with this injury. Methods A total of 356 patients in the study were diagnosed with TBI, with 94 patients classified as having mild TBI. We included patients with mild TBI for further evaluation if they had normal findings via brain computed tomography (CT) scans and also underwent brain MRI in the acute phase following trauma. As assessed by brain MRI, CCI was defined as a high-signal lesion in T2 sagittal images and a corresponding low-signal lesion as determined by axial gradient echo (GRE) imaging. Based on these criteria, we divided patients into two groups for further analysis : Group I (TBI patients with CCI) and Group II (TBI patients without CCI). Results A total of 56 patients were enrolled in this study (including 16 patients in Group I and 40 patients in Group II). Analysis of clinical symptoms revealed a significant difference in headache severity between groups. Over 50% of patients in Group I experienced prolonged neurological symptoms including dizziness and gait disturbance and were more common in Group I than Group II (dizziness : 37 and 12% in Groups I and II, respectively; gait disturbance : 12 and 0% in Groups I and II, respectively). Conclusion The incidence of CCI in patients with mild TBI was approximately 29%. We suggest that brain MRI is a useful method to reveal the cause of persistent symptoms and predict clinical prognosis. PMID:26361529

    Background and Purpose We examined the characteristics of sleep disturbances and sleep patterns in the caregivers of patients with amnestic mild cognitive impairment (aMCI) and dementia. Methods We prospectively studied 132 patients (60 with aMCI and 72 with dementia) and their caregivers, and 52 noncaregiver controls. All caregivers and controls completed several sleep questionnaires, including the Pittsburgh Sleep Quality Index (PSQI). The patients were administered neuropsychological tests and the neuropsychiatric inventory to evaluate their behavioral and neuropsychiatric symptoms of dementia (BPSD). Results The PSQI global score was 6.25±3.88 (mean±SD) for the dementia caregivers and 5.47±3.53 for the aMCI caregivers. The Insomnia Severity Index (ISI) and short form of the Geriatric Depression Scale (GDS-S) predicted higher PSQI global scores in aMCI caregivers, and higher scores for the ISI, Epworth Sleepiness Scale (ESS), and GDS-S in dementia caregivers. BPSD, including not only agitation, depression, and appetite change in dementia patients, but also depression, apathy, and disinhibition in aMCI patients, was related to impaired sleep quality of caregivers, but nighttime behavior was not. Age and gender were not risk factors for disturbed sleep quality. Conclusions Dementia and aMCI caregivers exhibit impaired quality of sleep versus non-caregivers. ISI, GDS-S, and ESS scores are strong indicators of poor sleep in dementia caregivers. In addition, some BPSD and parts of the neuropsychological tests may be predictive factors of sleep disturbance in dementia caregivers. PMID:25324879

    Purpose COPD is mainly caused by tobacco smoking and is associated with a high frequency of coronary artery disease. There is growing recognition that the inflammation in COPD is not only confined to the lungs but also involves the systemic circulation and can impact nonpulmonary organs, including blood vessels. α1-antitrypsin–low-density lipoprotein (AT-LDL) complex is an oxidatively modified LDL that accelerates atherosclerosis. Curcumin, one of the best-investigated natural products, is a powerful antioxidant. However, the effects of curcumin on AT-LDL remain unknown. We hypothesized that Theracurmin®, a highly absorptive curcumin with improved bioavailability using a drug delivery system, ameliorates the inflammatory status in subjects with mild COPD. Patients and methods This is a randomized, double-blind, parallel-group study. Subjects with stages I–II COPD according to the Japanese Respiratory Society criteria were randomly assigned to receive 90 mg Theracurmin® or placebo twice a day for 24 weeks, and changes in inflammatory parameters were evaluated. Results There were no differences between the Theracurmin® and placebo groups in terms of age, male/female ratio, or body mass index in 39 evaluable subjects. The percent changes in blood pressure and hemoglobin A1c and LDL-cholesterol, triglyceride, or high-density lipoprotein-cholesterol levels after treatment were similar for the two groups. However, the percent change in the AT-LDL level was significantly (P=0.020) lower in the Theracurmin® group compared with the placebo group. Conclusion Theracurmin® reduced levels of atherosclerotic AT-LDL, which may lead to the prevention of future cardiovascular events in mild COPD subjects. PMID:27616885

    Background: Patients with Alzheimer's disease (AD) manifest progressive decline in writing abilities. Most studies on agraphia in AD have been performed in the alphabetic system, such as English. However, these findings may not be applicable to other written language systems. The unique features of the Chinese written script could affect the patterns of agraphia in Chinese AD patients. The aim of this study was to explore the features of writing errors in Chinese patients with AD and amnestic mild cognitive impairment (a-MCI), as well as to study the relationship between their writing errors and neuropsychological functions. Methods: In this study, we performed an observational study in a group of subjects including 17 AD patients, 14 patients with a-MCI, and 16 elderly healthy controls. We analyzed the writing errors in these subjects and also studied the relationship between their writing errors and neuropsychological functions. Results: Our study showed that in patients whose mother tongue is Chinese, writing ability was comparatively well preserved in the MCI phase but significantly impaired when the disease progressed to the stage of AD. The writing errors showed corresponding increase with the severity of cognition decline, both in the types of errors and rate of occurrence. Analysis of the writing errors showed that word substitution and unintelligible words were the most frequent error types that occurred in all the three study groups. The occurrence rate of unintelligible words was significantly higher in the AD group compared with the a-MCI group (P = 0.024) and control group (P = 0.018). In addition, the occurrence rates of word substitution were also significantly higher in AD (P = 0.013) and a-MCI groups (P = 0.037) than that of control group. However, errors such as totally no response, visuospatial impairment, paragraph agraphia, ideograph, and perseverative writing errors were only seen in AD group. Besides, we also found a high occurrence rate of

    Background This prospective, randomized, controlled clinical trial compared changes in primary outcome measures of claudication onset time (COT) and peak walking time (PWT), and secondary outcomes of submaximal exercise performance, daily ambulatory activity, vascular function, inflammation, and calf muscle hemoglobin oxygen saturation (StO2) in patients with symptomatic peripheral artery disease (PAD) following new exercise training using a step watch (NEXT Step) home‐exercise program, a supervised exercise program, and an attention‐control group. Methods and Results One hundred eighty patients were randomized. The NEXT Step program and the supervised exercise program consisted of intermittent walking to mild‐to‐moderate claudication pain for 12 weeks, whereas the controls performed light resistance training. Change scores for COT (P<0.001), PWT (P<0.001), 6‐minute walk distance (P=0.028), daily average cadence (P=0.011), time to minimum calf muscle StO2 during exercise (P=0.025), large‐artery elasticity index (LAEI) (P=0.012), and high‐sensitivity C‐reactive protein (hsCRP) (P=0.041) were significantly different among the 3 groups. Both the NEXT Step home program and the supervised exercise program demonstrated a significant increase from baseline in COT, PWT, 6‐minute walk distance, daily average cadence, and time to minimum calf StO2. Only the NEXT Step home group had improvements from baseline in LAEI, and hsCRP (P<0.05). Conclusions NEXT Step home exercise utilizing minimal staff supervision has low attrition, high adherence, and is efficacious in improving COT and PWT, as well as secondary outcomes of submaximal exercise performance, daily ambulatory activity, vascular function, inflammation, and calf muscle StO2 in symptomatic patients with PAD.

    Background Pressure overload due to aortic stenosis (AS) causes maladaptive ventricular and vascular remodeling that can lead to pulmonary hypertension, heart failure symptoms, and adverse outcomes. Retarding or reversing this maladaptive remodeling and its unfavorable hemodynamic consequences has potential to improve morbidity and mortality. Preclinical models of pressure overload have shown that phosphodiesterase type 5 (PDE5) inhibition is beneficial, however the use of PDE5 inhibitors in patients with AS is controversial because of concerns about vasodilation and hypotension. Methods and Results We evaluated the safety and hemodynamic response of 20 subjects with severe symptomatic AS (mean aortic valve area 0.7±0.2 cm2, ejection fraction 60±14%) who received a single oral dose of sildenafil (40mg or 80mg). Compared to baseline, after 60 minutes sildenafil reduced systemic (−12%, p<0.001) and pulmonary (−29%, p=0.002) vascular resistance, mean pulmonary artery (−25%, p<0.001) and wedge (−17%, p<0.001) pressure, and increased systemic (+13%, p<0.001) and pulmonary (+45%, p<0.001) vascular compliance and stroke volume index (+8%, p=0.01). These changes were not dose dependent. Sildenafil caused a modest decrease in mean systemic arterial pressure (−11%, p<0.001), but was well-tolerated with no episodes of symptomatic hypotension. Conclusions This study shows for the first time that a single dose of a PDE5 inhibitor is safe and well-tolerated in patients with severe AS and is associated with acute improvements in pulmonary and systemic hemodynamics resulting in biventricular unloading. These findings support the need for longer-term studies to evaluate the role of PDE5 inhibition as adjunctive medical therapy in patients with AS. PMID:22447809

    Alzheimer's disease (AD) is the most common cause of dementia worldwide. Amnestic mild cognitive impairment (aMCI) is often the prodromal stage to AD. Most patients with aMCI harbor the pathologic changes of AD and demonstrate transition to AD at a rate of 10%-15% per year. Patients with AD and aMCI experience progressive brain metabolite changes. Accumulating evidence indicates that the asymmetry changes of left and right brain happen in the early stage of AD. However, the features of asymmetry changes in both anterior cingulate gyrus (ACG) and posterior cingulate gyrus (PCG) are still unclear. Here, we examine the left-right asymmetry changes of metabolites in ACG and PCG. Fifteen cases of mild AD patients meeting criteria for probable AD of NINDS-ADRDA, thirteen cases of aMCI according to the Mayo Clinic Alzheimer's Disease Research Center criteria, and sixteen cases of age-matched normal controls (NC) received Proton magnetic resonance spectroscopy ((1)H-MRS) for measurement of NAA/mI, NAA/Cr, Cho/Cr, and mI/Cr ratios in the PCG and ACG bilaterally. We analyzed (1)H-MRS data by paired t-test to validate the left-right asymmetry of (1)H-MRS data in the PCG and ACG. In AD, there was a significant difference in mI/Cr between the left and right ACG (P<0.001) and the left and right PCG (P=0.007). In aMCI, there was a significant difference in mI/Cr between the left and right ACG (P<0.001). In NC, there were no differences in the ratio value of metabolites NAA/mI, NAA/Cr, Cho/Cr, and mI/Cr between the left and right ACG and PCG. Thus, the left-right asymmetry of mI/Cr in the ACG and PCG may be an important biological indicator of mild AD. PMID:27423359

    Chronic fatigue syndrome (CFS) is an idiopathic disorder characterized by fatigue that is markedly exacerbated by physical exertion. In the present study, we tested the hypothesis that mild exercise (walking 1 mph [1 mile = 1.609 km] for 30 min) would provoke serum cytokine and cerebral blood flow abnormalities of potential pathogenic importance in CFS. Interleukin-1 beta, interleukin-6, and tumor necrosis factor alpha were nondetectable in sera of CFS patients (n = 10) and healthy control subjects (n = 10) pre- and postexercise. At rest, serum transforming growth factor beta (TGF-beta) levels were elevated in the CFS group compared with the control group (287 +/- 18 versus 115 +/- 5 pg/ml, respectively; P < 0.01). Serum TGF-beta and cerebral blood flow abnormalities, detected by single-photon emission-computed tomographic scanning, were accentuated postexercise in the CFS group. Although these findings were not significantly different from those in the control group, the effect of exercise on serum TGF-beta and cerebral blood flow appeared magnified in the CFS patients. Results of this study encourage future research on the interaction of physical exertion, serum cytokines, and cerebral blood flow in CFS that will adopt a more rigorous exercise program than the one used in this study.

    While the use of acupuncture as a complementary therapeutic method for treating MCI is popular in certain parts of the world, the underlying mechanism is still elusive. In the current study, we adopted multivariate Granger causality analysis (mGCA) to explore the causal interactions of brain networks involving acupuncture in mild cognitive impairment (MCI) patients compared to healthy controls (HC). The fMRI experiment was performed with two different paradigms: namely, deep acupuncture (DA) and superficial acupuncture (SA) at acupoint KI3. Results demonstrated that deep acupuncture could modulate the abnormal regions in MCI group. These regions are implicated in memory encoding and retrieving. This may relate to the purported therapeutically beneficial effects of acupuncture for the treatment of MCI. However, the most significant causal interactions were found in the sensorimotor regions in HC group. This may because acupuncture has a greater modulatory effect on patients with a pathological imbalance. This paper provides the preliminary neurophysiological evidence for the potential efficacy effect of acupuncture on MCI.

    Coated-platelets are procoagulant platelets that are elevated in stroke and are associated with stroke recurrence. In a previous study, prompted by data showing an increased risk for stroke following traumatic brain injury (TBI), we found that coated-platelet levels are elevated in patients with combat-related mild TBI (mTBI) several years after the injury, compared with controls. We now investigate in an expanded patient population whether parameters commonly recorded in mTBI are related to increased coated-platelet potential. Coated-platelet levels were assayed in 120 mTBI patients at intervals ranging from 6 months to 10 years from the last injury. Correlations were calculated between coated-platelet levels and age, gender, race/ethnicity, loss of consciousness, alteration in consciousness, post-traumatic amnesia, number of injuries, mechanism of injury, time since first and last injury, smoking, medications that may influence coated-platelet levels, and pertinent comorbid conditions. Significant correlations were detected between coated-platelet levels and number of injuries (p = 0.026), gender (p = 0.01), and time since last injury (p = 0.04). A multi-variable linear model analysis, including these three parameters and an additional three parameters (race/ethnicity, smoking, and mechanism of injury) that reached a p value of <0.2, showed that the number of injuries were predictive of coated-platelet levels (p = 0.004). These results support a mechanistic link between increased coated-platelet levels and repeated injuries in mTBI. Long-term studies will be required to determine the impact of increased prothrombotic potential in mTBI patients. PMID:26414016

    Defining cut points (CPs) for varying levels of pain intensity is important for assessing changes in patient's functional status, and guiding the development and evaluation of treatment options. We aimed to summarize CPs identified in the literature for mild, moderate, and severe pain on the numeric rating scale (NRS), and recommend optimal CPs for cancer and non-cancer patients. We searched MEDLINE and EMBASE (inception to May 2015) for studies that used CPs to classify pain intensity on the NRS among patients with cancer or non-cancer conditions leading to acute or chronic pain. A CP was defined as the upper bound of a mild or moderate pain category. Of 1,556 identified articles, 27 were included for review. Among patients with cancer pain, mild-moderate pain CPs ranged from 1 to 4 (mean, 3.5±1.08), with CP4 being the most recommended CP (80%). For moderate-severe pain, CPs ranged from 4 to 7 (mean, 6.2±0.92), and CP6 (50%) was the optimal CPs. Among patients with non-cancer pain, mild-moderate pain CPs ranged from 2 to 5 (mean, 3.62±0.78), and CP4 was the most frequently used CP (52.9%). For moderate-severe non-cancer pain, CPs ranged from 4 to 8 (mean, 6.5±0.99), and CP6 (41.2%) was the most frequently recommended CP. A wide range of CPs for mild, moderate, and severe pain categories were identified in the literature among both cancer and non-cancer patient populations. Further studies are needed to delineate more accurate and precise CPs for pain intensity. PMID:26541396

    Muscle dysfunction is a major comorbidity in Chronic Obstructive Pulmonary Disease (COPD). Several biological mechanisms including epigenetic events regulate muscle mass and function in models of muscle atrophy. Investigations conducted so far have focused on the elucidation of biological mechanisms involved in muscle dysfunction in advanced COPD. We assessed whether the epigenetic profile may be altered in the vastus lateralis of patients with mild COPD, normal body composition, and mildly impaired muscle function and exercise capacity. In vastus lateralis (VL) of mild COPD patients with well-preserved body composition and in healthy age-matched controls, expression of DNA methylation, muscle-enriched microRNAs, histone acetyltransferases (HTAs) and deacetylases (HDACs), protein acetylation, small ubiquitin-related modifier (SUMO) ligases, and muscle structure were explored. All subjects were clinically evaluated. Compared to healthy controls, in the VL of mild COPD patients, muscle function and exercise capacity were moderately reduced, DNA methylation levels did not differ, miR-1 expression levels were increased and positively correlated with both forced expiratory volume in one second (FEV1) and quadriceps force, HDAC4 protein levels were increased, and muscle fiber types and sizes were not different. Moderate skeletal muscle dysfunction is a relevant feature in patients with mild COPD and preserved body composition. Several epigenetic events are differentially expressed in the limb muscles of these patients, probably as an attempt to counterbalance the underlying mechanisms that alter muscle function and mass. The study of patients at early stages of their disease is of interest as they are a target for timely therapeutic interventions that may slow down the course of the disease and prevent the deleterious effects of major comorbidities.

    Background: No standard protocols are available for cognitive rehabilitation (CR) in conditions like Major or Mild Neurocognitive disorder (M-NCD or m-NCD, respectively); however, preliminary data seem to indicate that such interventions might have cost-effective beneficial effects and are free from side effect or adverse events. Three basic approaches are known: cognitive stimulation (CS), cognitive training (CT), and CR. Objective: Aim of this study was to assess the efficacy of a protocol of group intensive cognitive activation (g-ICA) in patients with both M-NCD and m-NCD; the protocol was specifically arranged in our Research Institute, based on the principles of the central role of the patient and the mediation pedagogy. Subjects and Methods: Sixteen patients with M-NCD and fifteen patients with m-NCD were enrolled, as well as eleven patients with M-NCD who were used as a control group (CG). The intervention was carried-out by a clinical neuropsychologist with daily group sessions over a period of 2 months. Neuropsychological assessment was performed at baseline and after the completion of the rehabilitative intervention. Results: General cognitive functioning, attention, ideomotor praxis and visual memory scores were found to be significantly increased in all patients. Beneficial and significant effects were also found for constructive praxis in M-NCD and for executive functioning in m-NCD. All areas of the language function were significantly ameliorated in m-NCD, while this happened only for verbal repetition and syntax-grammar comprehension in M-NCD. No changes were detected for long- and short-term verbal memory, which were found to be worsened in controls without activation. Conclusion: Our findings seem to indicate that g-ICA might be effective in inducing beneficial changes on the general cognitive functioning and other specific functions in patients with both m-NCD and M-NCD. Moreover, the specific protocol proposed, even if susceptible of important

    OBJECTIVE--To assess the influence of both sympathetic (plasma noradrenaline concentrations) and parasympathetic (baroreflex activation) tone on survival in patients with congestive heart failure. DESIGN--Invasive study with determination of parasympathetic activity and follow up for at least 4.5 years. SUBJECTS--35 patients with sinus rhythm and mild to moderate heart failure (New York Heart Association grades II-III) (mean age 53 (SD 3)). RESULTS--20 patients whose hearts survived were compared with 15 patients whose hearts did not (12 died and three received transplants). The two groups differed significantly in terms of mean arterial blood pressure (98 (3) v 90 (3) mm Hg), heart rate (82 (2) v 93 (4) beats/min), and mean pulmonary artery pressure (24 (3) v 35 (2) mm Hg) (all P < 0.05), while cardiac index, stroke volume index, and right atrial pressures were not different. The survivors had significantly lower plasma renin activities (3.6 (0.8) v 9.0 (3.6) angiotensin I/ml/h; P < 0.05) and tended to have lower noradrenaline values than non-survivors (170 (23) v 286 (74) pg/ml) at baseline. Baroreflex sensitivity was significantly lower in non- survivors than in survivors (1.3 (0.2) v 2.3 (0.3) ms/mm/Hg); P < 0.02). As the time of cardiac transplantation is dependent on complex logistical factors the three patients who received a transplant were excluded from the analysis of survival time. The risk of death in relation to baroreflex sensitivity at the median sensitivity of 1.48 ms/mm Hg was calculated. Survival was significantly different (P < 0.04) between the resulting two groups; three of the 16 subjects with high baroreflex sensitivity died compared with nine of the 16 with a baroreflex sensitivity < 1.48 ms/mm Hg. When systemic blood pressure, pulmonary artery pressure, stroke volume index, plasma noradrenaline concentrations, and baroreflex sensitivity were entered into a Cox proportional hazards regression, only systolic blood pressure and plasma

    A woman in her late 40s presented with excessive per vagina (PV) bleeding and uterine fibroid. She reported excessive PV bleeding after starting Esmya; she was brought in by ambulance to the emergency department with profuse bleeding. Abnormal uterine bleeding (AUB) developed after selective progesterone receptor modulator (SPRM) administration in this symptomatic patient with uterine fibroid. The drug was withheld and surgical treatment considered. Progressive deterioration of PV bleeding after receiving SPRM led to an urgent laparoscopic total hysterectomy, which had to be postponed due to severe anaemia. Surgery took place regardless because the excessive bleeding continued. Histology revealed a 6 cm submucosal uterine fibroid (SMUF) and adenomyosis. Physicians prescribing SPRMs to stop PV bleeding should be aware of potential AUB, which could lead to urgent hysterectomy. The mechanism of action of SPRMs is not clearly understood. Awareness of the side effects of Esmya, such as AUB, must be kept in mind when administering SPRMs. PMID:25976198

    Intracranial atherosclerotic disease is a common cause of stroke worldwide, causing approximately 10 % of strokes in the USA and up to 50 % in Asian populations. Recurrent stroke risks are particularly high in those with a stenosis of 70 % or more and a recent transient ischemic attack or stroke. Warfarin has been associated with higher major hemorrhage rates and no reduction of recurrent stroke compared to aspirin in patients with symptomatic intracranial stenosis. After early trials showed the feasibility of stenting, two randomized trials compared stenting plus medical management to medical management alone in symptomatic intracranial stenosis. Stenting was linked with increased risk and showed no benefit in any subpopulation of patients. Aggressive medical management in the Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial was associated with half the risk of stroke compared to that in similar patients in a previous symptomatic intracranial stenosis trial after adjustment of confounding characteristics. Aggressive medical management comprises risk factor control, including a target systolic blood pressure <140 mmHg, a low density lipoprotein <70 mg/dL, hemoglobin A1C <7.0 %, and lifestyle management that incorporates exercise, smoking cessation and weight management, and the use of antithrombotics.

    Summary Background there is only a paucity of studies dealing with bone remodeling within the tunnels after anterior cruciate ligament (ACL) reconstruction. The objective of this study was to evaluate the influence of tendon graft type and surgical fixation technique on bone tunnel remodeling in patients with symptomatic knees after ACL reconstruction. Methods in a retrospective study 99mTc-HDP bone tracer uptake (BTU) in SPECT/CT of 57 knees with symptoms of pain and/or instability after ACL reconstruction was investigated. All 57 knees were subdivided according their anatomy (femur and tibia), fixation (articular versus extra-articular fixation) and graft types into eight groups: femoral-articular versus extra-articular fixation using bone-patellar tendon-bone (BPTB) and hamstring autografts; tibial-articular versus extra-articular fixation using patellar tendon and hamstring autografts; BTU grading for each area of the localisation scheme were recorded. Tunnel diameter and length was measured in the CT scans. Results BTU was higher for the articular fixation in the femur and for the extra-articular fixation in the tibial tunnel. Patellar tendon graft fixation showed a significantly higher BTU in the superior-lateral and posterior-central area of the tibia, meaning the areas of the tibial tunnel near the entrance into the joint. Tunnel enlargement correlated significantly with increased BTU (p<0.05). Conclusion assessment of in vivo bone tunnel remodelling in symptomatic patients after ACL reconstruction revealed different patterns of BTU with regards to graft and fixation method. PMID:26958543

    Mild cognitive impairment (MCI) can occur early in the course of Parkinson's disease (PD), and its presence increases the risk of developing dementia. Determining the cortical changes associated with MCI in PD, thus, may be useful in predicting the future development of dementia. To address this objective, 37 patients with PD, divided into 2 groups according to the presence or absence MCI (18 with and 19 without) and 16 matched controls, underwent anatomic magnetic resonance imaging. Corticometry analyses were performed to measure the changes in cortical thickness and surface area as well as their correlation with disease duration. Compared with healthy controls, the PD-MCI group exhibited increased atrophy and changes of local surface area in the bilateral occipital, left temporal, and frontal cortices; whereas the PD non-MCI group exhibited only unilateral thinning and decreased surface area in the occipital lobe and in the frontal cortex. In addition, a comparison between the PD-MCI and PD non-MCI groups revealed increased local surface area in the occipital lobe, temporal lobe, and postcentral gyrus for the cognitively impaired patients. It is noteworthy that, in the PD-MCI group, cortical thickness had a significant negative correlation with disease duration in the precentral, supramarginal, occipital, and superior temporal cortices; whereas, in the PD non-MCI group, such a correlation was absent. The findings from this study reveal that, at the same stage of PD evolution, the presence of MCI is associated with a higher level of cortical changes, suggesting that cortical degeneration is increased in patients with PD because of the presence of MCI.

    Three major clinical subgroups are usually distinguished in Mucopolysaccharidosis type I: Hurler (MPS IH, severe presentation), Hurler-Scheie (MPS IH/S, intermediate) and Scheie (MPS IS, mild). To facilitate treatment with hematopoietic stem-cell transplantation, early diagnosis is important for MPS IH patients. Although screening for MPS I in newborns would allow detection at an early age, it may be difficult to predict the phenotype on the basis of the genotype in these infants. Extra diagnostic tools are thus required. Based on the hypothesis that distinct MPS I phenotypes may result from differences in residual α-l-iduronidase (IDUA) activity, we modified the common IDUA assay using the substrate 4-methylumbelliferyl-α-l-iduronide to allow quantification of low IDUA activity in MPS I fibroblasts. Enzyme incubation was performed with high protein concentrations at different time points up to 8h. Mean residual IDUA activity was 0.18% (range 0-0.6) of the control value in MPS IH fibroblasts (n=5); against 0.27% (range 0.2-0.3) in MPS IH/S cells (n=3); and 0.79% (range 0.3-1.8) in MPS IS fibroblasts (n=5). These results suggest that residual IDUA activity and severity of the MPS I phenotype are correlated. Two MPS IS patients with rare (E276K/E276K) or indefinite (A327P/unknown) IDUA genotypes had residual IDUA activity in the MPS IS range, illustrating the usefulness of our approach. IDUA(E276K) was very unstable at 37°C, but more stable at 23°C, suggesting thermal instability. We conclude that this procedure for determining residual IDUA activity in fibroblasts of MPS I patients may be helpful to predict MPS I phenotype. PMID:23786846

    The objective of this study was to develop new risk classifications for conversion to Alzheimer's disease (AD) by comparing the relative reliability of classifiers in patients with mild cognitive impairment (MCI). The 397 MCI subjects and all baseline data, including characteristics, neuropsychological tests, cerebrospinal fluid biomarkers and MRI findings in Alzheimer's Disease Neuroimaging Initiative (ADNI), were used for analysis by Cox proportional hazard regression, bootstrap sampling, and c-index. Multivariate Cox regression analysis revealed the following factors to be associated with increased risk of conversion from MCI to AD during the 53-month follow-up period: AVLT 30-minute delayed recall, AVLT trial 1, Boston naming, logical delayed recall, trail-making B, CDR-sob, ADAS13, the cortical thickness of the right inferior temporal lobe (st91ta), and the left hippocampus volume. The combinations of ADAS13 at a cutoff point of 15.67 with CDR-sob at 1.5 or with the cortical thickness of the right inferior temporal lobe at 2.56 mm3 produced high conversion rates of 92.7% (82.4%-100.0%) and 88.8% (77.3%-100.0%), respectively, at 48 months. The discriminative ability based on c-index for the proposed combination was 0.68. The sample size was estimated as 504 in the group with a combination of ADAS13 and CDR-sob whose conversion rate is highest. The combination of ADAS13 with CDR-sob at an optimal cutoff point has a high reliability in classifying the MCI patients into high- and low-risk conversion to AD and will be benefit for patients' assessment and potentially facilitate the clinical development of novel therapeutics.

    Aim and Objectives: To investigate the efficacy of 0.1% tacrolimus with Colgate Oraguard-B paste for the treatment of patients with oral lichen planus (OLP). Materials and Methods: One hundred and fifty patients with symptomatic OLP participated in the study, who had clinically and histopathologically proven OLP. In this study, patients were provided with 0.1% tacrolimus ointment with Colgate Oraguard-B paste as the study medication. Patients were asked to use the medication over the areas three times a day until resolution of the lesion. Patients were recalled to assess the drug response every 15 days. The duration of treatment ranged from 3 months to 4 months, with follow-up of 2 years and 6 months. Statistical Analysis: The Wilcoxon signed-rank test was performed, which is a nonparametric statistical hypothesis test for comparing two related samples, matched samples or repeated measurements on a single sample to assess whether their population mean ranks differ (i.e., it is a paired difference test). In our study, the pre- and post-Visual Analogue Scale (VAS) values were compared and the mean, standard deviation and P values were calculated. Results: Of 150 patients, 71 (47.33%) patients had complete resolution of the lesion to the topical tacrolimus therapy. Sixty-five (43.33%) patients had marked resolution of their lesions, i.e., the size of the lesion was decreased. Fourteen (9.33%) patients had remission of lesion (reduction in burning sensation and size of lesion) in symptoms as recorded by the VAS. Conclusion: Topical tacrolimus ointment 0.1% in Oraguard-B paste is an effective treatment for different types of OLP. PMID:27134451

    Accurately identifying the patients that have mild cognitive impairment (MCI) who will go on to develop Alzheimer's disease (AD) will become essential as new treatments will require identification of AD patients at earlier stages in the disease process. Most previous work in this area has centred around the same automated techniques used to diagnose AD patients from healthy controls, by coupling high dimensional brain image data or other relevant biomarker data to modern machine learning techniques. Such studies can now distinguish between AD patients and controls as accurately as an experienced clinician. Models trained on patients with AD and control subjects can also distinguish between MCI patients that will convert to AD within a given timeframe (MCI-c) and those that remain stable (MCI-s), although differences between these groups are smaller and thus, the corresponding accuracy is lower. The most common type of classifier used in these studies is the support vector machine, which gives categorical class decisions. In this paper, we introduce Gaussian process (GP) classification to the problem. This fully Bayesian method produces naturally probabilistic predictions, which we show correlate well with the actual chances of converting to AD within 3 years in a population of 96 MCI-s and 47 MCI-c subjects. Furthermore, we show that GPs can integrate multimodal data (in this study volumetric MRI, FDG-PET, cerebrospinal fluid, and APOE genotype with the classification process through the use of a mixed kernel). The GP approach aids combination of different data sources by learning parameters automatically from training data via type-II maximum likelihood, which we compare to a more conventional method based on cross validation and an SVM classifier. When the resulting probabilities from the GP are dichotomised to produce a binary classification, the results for predicting MCI conversion based on the combination of all three types of data show a balanced accuracy

  18. Effect of Acetazolamide on Visual Function in Patients With Idiopathic Intracranial Hypertension and Mild Visual Loss

    2015-01-01

    IMPORTANCE Acetazolamide is commonly used to treat idiopathic intracranial hypertension (IIH), but there is insufficient information to establish an evidence base for its use. OBJECTIVE To determine whether acetazolamide is beneficial in improving vision when added to a low-sodium weight reduction diet in patients with IIH and mild visual loss. DESIGN, SETTING, AND PARTICIPANTS Multicenter, randomized, double-masked, placebo-controlled study of acetazolamide in 165 participants with IIH and mild visual loss who received a low-sodium weight-reduction diet. Participants were enrolled at 38 academic and private practice sites in North America from March 2010 to November 2012 and followed up for 6 months (last visit in June 2013). All participants met the modified Dandy criteria for IIH and had a perimetric mean deviation (PMD) between −2 dB and −7 dB. The mean age was 29 years and all but 4 participants were women. INTERVENTIONS Low-sodium weight-reduction diet plus the maximally tolerated dosage or acetazolamide (up to 4 g/d) or matching placebo for 6 months. MAIN OUTCOMES AND MEASURES The planned primary outcome variable was the change in PMD from baseline to month 6 in the most affected eye, as measured by Humphrey Field Analyzer. Perimetric mean deviation is a measure of global visual field loss (mean deviation from age-corrected normal values), with a range of 2 to −32 dB; larger negative values indicate greater vision loss. Secondary outcome variables included changes in papilledema grade, quality of life (Visual Function Questionnaire 25 [VFQ-25] and 36-Item Short Form Health Survey), headache disability, and weight at month 6. RESULTS The mean improvement in PMD was greater with acetazolamide (1.43 dB, from −3.53 dB at baseline to −2.10 dB at month 6; n = 86) than with placebo (0.71 dB, from −3.53 dB to −2.82 dB;n = 79); the difference was 0.71 dB (95% CI, 0 to 1.43 dB; P= .050). Mean improvements in papilledema grade (acetazolamide: −1

    Benefits of triple therapy with a long-acting muscarinic antagonist (LAMA), added to inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA), have been demonstrated. Limited data assessing the efficacy of the LAMA umeclidinium (UMEC) added to ICS/LABA are available. The aim of this study is to evaluate the efficacy and safety of UMEC added to ICS/LABAs in patients with moderate-to-very-severe COPD. This is a multicentre, randomised, double-blind, parallel-group study. Patients were symptomatic (modified Medical Research Council Dyspnoea Scale score ⩾2), despite receiving ICS/LABA (fluticasone propionate/salmeterol (FP/SAL, branded) 500/50 mcg, budesonide/formoterol (BD/FOR, branded) 200/6 mcg or 400/12 mcg, or other ICS/LABAs) ⩾30 days before the run-in (7±2 days). Patients were randomised 1:1 to once-daily UMEC 62.5 mcg or placebo (PBO), added to twice-daily open-label ICS/LABA for 12 weeks. Primary end point was trough forced expiratory volume in 1 s (FEV1) at Day 85; secondary end point was weighted mean (WM) 0–6 h FEV1 at Day 84; other end points included COPD Assessment Test (CAT) score and Transition Dyspnoea Index (TDI) score. Adverse events (AEs) were investigated. In the UMEC+ICS/LABA and PBO+ICS/LABA groups, 119 and 117 patients were randomised, respectively. Patients received FP/SAL (40%), BD/FOR (43%) and other ICS/LABAs (17%). UMEC+ICS/LABA resulted in significant improvements in trough FEV1 (Day 85) and in WM 0–6 h FEV1 (Day 84) versus PBO+ICS/LABA (difference: 123 and 148 ml, respectively, both P<0.001). Change from baseline for UMEC+ICS/LABA versus PBO+ICS/LABA was significantly different for CAT score at Day 84 (−1.31, P<0.05), but not for TDI score (0.40, P=0.152). AE incidence was similar with UMEC+ICS/LABA (38%) and PBO+ICS/LABA (42%). UMEC+ICS/LABA improved lung function and CAT score in patients with symptomatic COPD versus PBO+ICS/LABA (ClinicalTrials.gov NCT02257372). PMID:27334739

    This study was designed to assess the efficacy of xamoterol in 14 patients with mild to moderate heart failure over a period of 18 months. A beneficial effect on exercise capacity and a lowering of heart rate on exercise was sustained, and ejection fraction did not change, although some deterioration may be expected over this length of time in patients with heart failure. Xamoterol is safe and effective, and its benefits are maintained over at least 18 months. PMID:2572265

    Heart failure is a progressive cardiovascular disorder and, in most cases, begins with atherosclerosis and ischemic heart disease. The prognosis of patients with heart failure is poor, even with improvement on the management of all forms of ischemic heart disease. There have been studies on heart failure using a single nutrient or a combination of multiple nutrients. Results are mixed. The aim of this study was to assess the influence of multiple micronutrient supplementation using the quality of life measure on patients with heart failure secondary to ischemic heart disease. This prospective case series followed 12 patients for a period between 3 to 8 months, using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) as the sole outcome measure. The primary outcome was a score change over time between the start and endpoint of treatment. Change in MLHFQ mean total score was 27.08 ± 20.43 and mean symptoms score was 4.67 ± 3.34. Paired t-test showed a difference between baseline and endpoint of treatment (P < 0.001), which was statistically significant. A high dose of multiple micronutrients may have beneficial effects on cardiac function in patients with symptomatic heart failure. This study indicates the need for long-term controlled studies to test the efficacy and safety of this economic approach in managing heart failure. PMID:26417534

    Patients with rosacea form a unique subset of the sensitive skin population because of the barrier defects inherent in this condition and the increased propensity for burning/stinging from topical products. This propensity for burning/ stinging when medications, skin care products, or cosmetics are applied to the facial skin has been frequently documented but never quantified. The objective of this 2-week study was to determine the prevalence of heightened neurosensory perceptions of burning/stinging in a random population of 40 women with mild to moderate rosacea defined as 15 or fewer inflammatory papules or pustules. Also evaluated was the effect of azelaic acid 15% gel on barrier function and facial stinging utilizing transepidermal water loss (TEWL), corneometry, and lactic acid facial sting tests as noninvasive measurement criteria. At baseline, the incidence of lactic acid stinging among these rosacea subjects was 62.5%, which is substantially higher than observed in the general population. Two weeks after application of azelaic acid 15% gel, no evidence of barrier damage was noted on TEWL or corneometry tests. Moreover, there was no statistical relationship between lactic acid stinging and a stinging response that is occasionally reported with exposure to azelaic acid 15% gel. PMID:15551720

    Older adults with mild cognitive impairment (MCI) manifest impaired explicit memory. However, studies on implicit memory such as repetition effects in persons with MCI have been limited. In the present study, 17 MCI patients and 16 healthy normal controls (NC) completed a modified delayed-match-to-sample task while undergoing functional magnetic resonance imaging. We aim to examine the neural basis of repetition; specifically, to elucidate whether and how repetition-related brain responses are altered in participants with MCI. When repeatedly rejecting distracters, both NC and MCI showed similar behavioral repetition effects; however, in both whole-brain and region-of-interest analyses of functional data, persons with MCI showed reduced repetition-driven suppression in the middle occipital and middle frontal gyrus. Further, individual difference analysis found that activation in the left middle occipital gyrus was positively correlated with rejecting reaction time and negatively correlated with accuracy rate, suggesting a predictor of repetition behavioral performance. These findings provide new evidence to support the view that neural mechanisms of repetition effect are altered in MCI who manifests compensatory repetition-related brain activities along with their neuropathology.

    Abstract The periaqueductal gray (PAG) plays a pivotal role in pain modulation. We attempted to examine the relation between injury of the PAG and central pain in patients with mild traumatic brain injury (TBI). Sixty-one patients with mild TBI with central pain and 31 healthy control subjects were recruited for this study. Visual analog scale (VAS) was used for evaluation of central pain. The region of interest was defined for the PAG and the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured. The FA value was significantly lower in the patient group than in the control group (P < 0.05). However, no significant difference in the ADC value was observed between the patient and control groups (P > 0.05). VAS score of the patient group showed significant moderate negative correlation with the FA (r = −0.38), while no significant correlation was observed between VAS score and the ADC value (P < 0.05). We demonstrated injury of the PAG in patients with central pain following mild TBI and the degree of injury of the PAG was closely related to the degree of central pain. PMID:27368020

    Objective Receptor for advanced glycation end products (AGEs; RAGE) binds to both AGEs and amyloid-beta peptides. RAGE is involved in chronic complications of type 2 diabetes and Alzheimer’s disease. We aimed to investigate the roles of RAGE, AGEs and the Gly82Ser polymorphism of RAGE in mild cognitive impairment (MCI) among type 2 diabetes patients. Methods Of the 167 hospitalized type 2 diabetes patients recruited, 82 satisfied the diagnostic criteria for MCI, and 85 matched control individuals were classified as non-MCI. Demographic data were collected, and the soluble RAGE (sRAGE) concentrations, serum AGE-peptide (AGE-P) levels, RAGE Gly82Ser genotype and neuropsychological test results were examined. Results The MCI group exhibited a decreased sRAGE level (0.87±0.35 vs. 1.05±0.52 ng/ml, p<0.01) and an increased serum AGE-P level (3.54±1.27 vs. 2.71±1.18 U/ml, p<0.01) compared with the control group. Logistic regression analysis indicated that each unit reduction in the sRAGE concentration increased the MCI risk by 54% (OR 0.46[95% CI 0.22–0.96], p = 0.04) and that each unit increase in the AGE-P level increased the MCI risk by 72% in the type 2 diabetes patients (OR 1.72[95% CI 1.31–2.28], p<0.01). The serum sRAGE level was negatively correlated with the score on the trail making test-B (TMT-B) (r = -0.344, p = 0.002), which indicates early cognitive deficits related to diabetes. Moreover, the AGE-P level was positively correlated with multiple cognitive domains (all p<0.05). No significant differences in the neuropsychological test results or serum RAGE concentrations between the different RAGE genotypes or in the RAGE genotype frequencies between the MCI and control groups were identified (all p>0.05). Conclusions The RAGE pathway partially mediates AGE-induced MCI in diabetic patients. The serum AGE-P level may serve as a serum biomarker of MCI in these individuals, and sRAGE represents a predictor and even a potential intervention target of

    In the present study, we investigated the prognostic value of MR-proANP (mid-regional pro-atrial natriuretic peptide). We consecutively evaluated a catheterization laboratory cohort of 2700 patients with symptomatic CAD (coronary artery disease) [74.1% male; ACS (acute coronary syndrome), n=1316; SAP (stable angina pectoris), n=1384] presenting to the Cardiology Department of a large primary care hospital, all of whom underwent coronary angiography. Serum MR-proANP and other laboratory markers were sampled at the time of presentation or in the catheterization laboratory. Clinical outcome was assessed by hospital chart analysis and telephone interviews. The primary end point was all-cause death at 3 months after enrolment. Follow-up data were complete in 2621 patients (97.1%). Using ROC (receiver operating characteristic) curves, the AUC (area under the curve) of 0.73 [95% CI (confidence interval), 0.67-0.79] for MR-proANP was significantly higher compared with 0.58 (95% CI, 0.55-0.62) for Tn-I (troponin-I; DeLong test, P=0.0024). According to ROC analysis, the optimal cut-off value of MR-proANP was at 236 pmol/l for all-cause death, which helped to find a significantly increased rate of all-cause death (n=76) at 3 months in patients with elevated baseline concentrations (≥236 pmol/l) compared with patients with a lower concentration level in Kaplan-Meier survival analysis (log rank, P<0.001). The predictive performance of MR-proANP was independent of other clinical variables or cardiovascular risk factors, and superior to that of Tn-I or other cardiac biomarkers (all: P<0.0001). MR-proANP may help in the prediction of all-cause death in patients with symptomatic CAD. Further studies should verify its prognostic value and confirm the appropriate cut-off value. PMID:22690794

    Memory for object locations, as part of spatial memory function, has rarely been studied in patients with Alzheimer dementia (AD), while studies in patients with Mild Cognitive Impairment (MCI) patients are lacking altogether. The present study examined categorical spatial memory function using the Location Learning Test (LLT) in MCI patients (n = 30), AD patients (n = 30), and healthy controls (n = 40). Two scoring methods were compared, aimed at disentangling positional recall (location irrespective of object identity) and object-location binding. The results showed that AD patients performed worse than the MCI patients on the LLT, both on recall of positional information and on recall of the locations of different objects. In addition, both measures could validly discriminate between AD and MCI patients. These findings are in agreement with the notion that visual cued-recall tests may have better diagnostic value than traditional (verbal) free-recall tests in the assessment of patients with suspected MCI or AD.

    Background: Although mental fatigue was well-recognized as one of the long-term consequences following mild traumatic brain injury (MTBI) that required ongoing support, evidences for the optimal management remained inadequate. Aims: To investigate the temporal profile of mental fatigue during the first year after MTBI and examine the impact of perceived social support on the recovery from post-MTBI fatigue. Study Design: Observational case-control study. Methods: This study was conducted among post-MTBI patients admitted to the emergency department in a tertiary-care hospital in Sichuan, China. During four waves of assessments at 1 week, 3, 6 and 12 months, mental fatigue was assessed through Mental Fatigue Scale (MFS) whereas social support was assessed by the Multidimensional Scale of Perceived Social Support (MSPSS). Results: There were 65.1%, 37.1%, 34.8% and 32.5% individuals being identified as those with mental fatigue at 1 week, 3, 6 and 12 months, respectively. The scores of MFS didn’t change substantially since 3 months post-injury. Compared to non-fatigued MTBI patients, those with long-lasting post- MTBI fatigue reported extremely lower level of perceived social support. Moreover, improved social support at 1 week was negatively associated with the occurrence of long-lasting fatigue. Conclusion: Sufficient social support could significantly decrease the occurrence of long-lasting mental fatigue among MTBI cases. It seemed of great importance to modify the emphasis of rehabilitation to include assessment and improvement of perceived social support at earlier stages after injury. PMID:27403383

    The benefit of induced hyperventilation for intracranial pressure (ICP) control after severe traumatic brain injury (TBI) is controversial. In this study, we investigated the impact of early and sustained hyperventilation on compliances of the cerebral arteries and of the cerebrospinal (CSF) compartment during mild hyperventilation in severe TBI patients. We included 27 severe TBI patients (mean 39.5 ± 3.4 years, 6 women) in whom an increase in ventilation (20% increase in respiratory minute volume) was performed during 50 min as part of a standard clinical CO(2) reactivity test. Using a new mathematical model, cerebral arterial compliance (Ca) and CSF compartment compliance (Ci) were calculated based on the analysis of ICP, arterial blood pressure, and cerebral blood flow velocity waveforms. Hyperventilation initially induced a reduction in ICP (17.5 ± 6.6 vs. 13.9 ± 6.2 mmHg; p < 0.001), which correlated with an increase in Ci (r(2) = 0.213; p = 0.015). Concomitantly, the reduction in cerebral blood flow velocities (CBFV, 74.6 ± 27.0 vs. 62.9 ± 22.9 cm/sec; p < 0.001) marginally correlated with the reduction in Ca (r(2) = 0.209; p = 0.017). During sustained hyperventilation, ICP increased (13.9 ± 6.2 vs. 15.3 ± 6.4 mmHg; p < 0.001), which correlated with a reduction in Ci (r(2) = 0.297; p = 0.003), but no significant changes in Ca were found during that period. The early reduction in Ca persisted irrespective of the duration of hyperventilation, which may contribute to the lack of clinical benefit of hyperventilation after TBI. Further studies are needed to determine whether monitoring of arterial and CSF compartment compliances may detect and prevent an adverse ischemic event during hyperventilation. PMID:21204704
