    2010-01-01

    Introduction The impact of anemia on functional outcome and mortality in patients suffering from non-traumatic intracerebral hemorrhage (ICH) has not been investigated. Here, we assessed the relationship between hemoglobin (HB) levels and clinical outcome after ICH. Methods One hundred and ninety six patients suffering from supratentorial, non-traumatic ICH were extracted from our local stroke database (June 2004 to June 2006). Clinical and radiologic computed tomography data, HB levels on admission, mean HB values and nadir during hospital stay were recorded. Outcome was assessed at discharge and 3 months using the modified Rankin score (mRS). Results Forty six (23.5%) patients achieved a favorable functional outcome (mRS ≤ 3) and 150 (76.5%) had poor outcome (mRS 4 - 6) at discharge. Patients with poor functional outcome had a lower mean HB (12.3 versus 13.7 g/dl, P < 0.001) and nadir HB (11.5 versus 13.0 g/dl, P < 0.001). Ten patients (5.1%) received red blood cell (RBC) transfusions. In a multivariate logistic regression model, the mean HB was an independent predictor for poor functional outcome at three months (odds ratio (OR) 0.73, 95% confidence interval (CI) 0.58-0.92, P = 0.007), along with National Institute of Health Stroke Scale (NIHSS) at admission (OR 1.17, 95% CI 1.11 - 1.24, P < 0.001), and age (OR 1.08, 95% CI 1.04 - 1.12, P < 0.001). Conclusions We report an association between low HB and poor outcome in patients with non-traumatic, supratentorial ICH. While a causal relationship could not be proven, previous experimental studies and studies in brain injured patients provide evidence for detrimental effects of anemia on brain metabolism. However, the potential risk of anemia must be balanced against the risk of harm from red blood cell infusion. PMID:20398266

    Summary Autism (ASD) is vastly heterogeneous, particularly in early language development. While ASD language trajectories in the first years of life are highly unstable, by early childhood these trajectories stabilize and are predictive of longer-term outcome. Early neural substrates that predict/precede such outcomes are largely unknown but could have considerable translational and clinical impact. Pre-diagnosis fMRI response to speech in ASD toddlers with relatively good language outcome was highly similar to non-ASD comparison groups and robustly recruited language-sensitive superior temporal cortices. In contrast, language-sensitive superior temporal cortices were hypoactive in ASD toddlers with poor language outcome. Brain-behavioral relationships were atypically reversed in ASD and a multimodal combination of pre-diagnostic clinical behavioral measures and speech-related fMRI response showed the most promise as an ASD prognosis classifier. Thus, before ASD diagnoses and outcome become clinically clear, distinct functional neuroimaging phenotypes are already present that can shed insight on an ASD toddler’s later outcome. PMID:25864635

    Background To assess the association of diabetes with postoperative limitation of activities of daily living (ADLs) after primary total knee arthroplasty (TKA). Methodology/Principal Findings We used the prospectively collected data from the Mayo Clinic Total Joint Registry to assess the association of diabetes and diabetes with complications with moderate-severe ADL limitation 2- and 5-years after primary TKA. Multivariable logistic regression with general estimating equations adjusted for preoperative ADL limitation, comorbidity and demographic and clinical covariates. Odds ratio (OR) and 95% confidence interval (CI) are presented. 7,139 primary TKAs at 2-years and 4,234 at 5-years constituted the cohorts. In multivariable-adjusted analyses, diabetes was associated with higher odds of moderate-severe limitation at 2- and 5-years, 1.71 (95% CI: 1.26, 2.32; P = 0.001) and 1.66 (95% CI: 1.13, 2.46; P = 0.01). Respective ORs for patients with diabetes with complications were 2.73 (95% CI: 1.47, 5.07; P = 0.001) and 2.73 (95% CI: 1.21, 6.15; P = 0.016). Sensitivity analyses that adjusted for anxiety and depression or anxiety, depression and ipsilateral hip involvement showed minimal attenuation of magnitude of the association. Conclusions/Significance In this large study of patients who underwent primary TKA, diabetes as well as its severity were independently associated with poorer functional outcome. Given the increasing rates of both diabetes as well as arthroplasty, more insight is needed into disease-related and treatment-related factors that underlie this higher risk of ADL limitation in patients with diabetes. Poor functional outcomes may be preventable by modifying the control of diabetes and associated comorbidity in pre- and post-arthroplasty periods. PMID:24236080

    Introduction Oxidative stress affects clinical outcome in critically ill patients. Although high-density lipoprotein (HDL) particles generally possess anti-oxidant capacities, deleterious properties of HDL have been described in acutely ill patients. The impact of anti-oxidant HDL capacities on clinical outcome in critically ill patients is unknown. We therefore analyzed the predictive value of anti-oxidant HDL function on mortality in an unselected cohort of critically ill patients. Method We prospectively enrolled 270 consecutive patients admitted to a university-affiliated intensive care unit (ICU) and determined anti-oxidant HDL function using the HDL oxidant index (HOI). Based on their HOI, the study population was stratified into patients with impaired anti-oxidant HDL function and the residual study population. Results During a median follow-up time of 9.8 years (IQR: 9.2 to 10.0), 69% of patients died. Cox regression analysis revealed a significant and independent association between impaired anti-oxidant HDL function and short-term mortality with an adjusted HR of 1.65 (95% CI 1.22–2.24; p = 0.001) as well as 10-year mortality with an adj. HR of 1.19 (95% CI 1.02–1.40; p = 0.032) when compared to the residual study population. Anti-oxidant HDL function correlated with the amount of oxidative stress as determined by Cu/Zn superoxide dismutase (r = 0.38; p<0.001). Conclusion Impaired anti-oxidant HDL function represents a strong and independent predictor of 30-day mortality as well as long-term mortality in critically ill patients. PMID:26978526

  6. Ipsilateral lower extremity joint involvement increases the risk of poor pain and function outcomes after hip or knee arthroplasty

    2013-01-01

    Background Poor pain and function outcomes are undesirable after an elective surgery such as total hip or knee arthroplasty (THA/TKA). Recent studies have indicated that the presence of contralateral joint influences outcomes of THA/TKA, however the impact of ipsilateral knee/hip involvement on THA/TKA outcomes has not been explored. The objective of this study was to assess the association of ipsilateral knee/hip joint involvement on short-term and medium-term pain and function outcomes after THA/TKA. Methods In this retrospective study of prospectively collected data, we used the data from the Mayo Clinic Total Joint Registry to assess the association of ipsilateral knee or hip joint involvement with moderate to severe pain and moderate to severe activity limitation at 2-year and 5-year follow-up after primary and revision THA and TKA using multivariable-adjusted logistic regression analyses. Results At 2 years, 3,823 primary THA, 4,701 primary TKA, 1,218 revision THA and 725 revision TKA procedures were studied. After adjusting for multiple covariates, ipsilateral knee pain was significantly associated with outcomes after primary THA (all P values <0.01): (1) moderate to severe pain: at 2 years, odds ratio (OR), 2.3 (95% confidence interval (CI) 1.5 to 3.6); at 5 years, OR 1.8 (95% CI 1.1 to 2.7); (2) moderate to severe activity limitation: at 2 years, OR 3.1 (95% CI 2.3 to 4.3); at 5 years, OR 3.6 (95% CI 2.6 to 5.0). Ipsilateral hip pain was significantly associated with outcomes after primary TKA (all P values <0.01): (1) moderate to severe pain: at 2 years, OR 3.3 (95% CI 2.3 to 4.7); at 5 years, OR 1.8 (95% CI 1.1 to 2.7); (2) moderate to severe activity limitation: at 2 years, OR 3.6 (95% CI 2.6 to 4.9); at 5 years, OR 2.2 (95% CI 1.6 to 3.2). Similar associations were noted for revision THA and TKA patients. Conclusions To the best of our knowledge, this is the first study showing that the presence of ipsilateral joint involvement after THA or TKA is

    The aim of this study was to further our understanding of the transformation process by identifying differentially expressed proteins in melanocytes compared with melanoma cell lines. Tandem mass spectrometry incorporating iTRAQ reagents was used as a screen to identify and comparatively quantify the expression of proteins in membrane-enriched samples isolated from primary human melanocytes or three melanoma cells lines. Real-time PCR was used to validate significant hits. Immunohistochemistry was used to validate the expression of proteins of interest in melanocytes in human skin and in melanoma-infiltrated lymph nodes. Publically available databases were examined to assess mRNA expression and correlation to patient outcome in a larger cohort of samples. Finally, preliminary functional studies were carried out using siRNAs to reduce the expression of a protein of interest in primary melanocytes and in a keratinocyte cell line. Two proteins, AHNAK and ANXA2, were significantly downregulated in the melanoma cell lines compared with melanocytes. Downregulation was confirmed in tumor cells in a subset of human melanoma-infiltrated human lymph nodes compared with melanocytes in human skin. Examination of Gene Expression Omnibus database data sets suggests that downregulation of AHNAK mRNA and mutation of the AHNAK gene are common in metastatic melanoma and correlates to a poor outcome. Knockdown of AHNAK in primary melanocytes and in a keratinocyte cell line led to a reduction in detectable cadherin-1. This is the first report that we are aware of which correlates a loss of AHNAK with melanoma and poor patient outcome. We hypothesize that AHNAK is required for the expression of functional cadherin-1. PMID:26672724

    Seligman's theory of causal attribution predicts that patients with a pessimistic explanatory style will have less favourable health outcomes. We identified 702 patients who had undergone 894 primary total knee replacements between 1993 and 2005, who responded to follow-up surveys at two (n = 783 knee replacements) and/or five years (n = 443 knee replacements) and had also completed the Minnesota Multiphasic Personality Inventory long before the joint replacement (median = 16.6 and 14.5 years for two- and five-year cohorts, respectively). Scores from the Minnesota Multiphasic Personality Inventory Optimism-Pessimism scale were used to categorise patients as pessimistic (t-score > 60) or non-pessimistic (t-score < or = 60). Multivariate logistic regression models assessing the effect of pessimistic explanatory style on pain or improvement in knee function were adjusted for gender, age, distance from the place of treatment and depression score. Pessimists reported (a) significantly more moderate or severe pain at two years with odds ratio 2.21 (95% confidence interval (CI) 1.12 to 4.35; p = 0.02), but not at five years when the odds ratio was 1.21 (95% CI 0.51 to 2.83; p = 0.67); and (b) less improvement in knee function at two years when the odds ratio was 0.53 (95% CI 0.30 to 0.96; p = 0.04), but not at five years when the odds ratio was 1.26 (95% CI 0.57 to 2.77; p = 0.57). No significant associations with moderate or severe limitation of activity were seen at two or five years. We conclude that a pessimistic explanatory style is associated with worse pain and functional outcomes two years after total knee replacement. PMID:20513876

    Missense mutation of p53 not only impairs its tumor suppression function, but also causes oncogenic gain of function (GOF). The molecular underpinning of mutant p53 (mutp53) GOF is not fully understood, especially for the potential roles of non-coding genes. Here we identify the microRNA expression profile (microRNAome) of mutp53 on Arg282 by controlled microarray experiments, and clarify the prognostic significance of mutp53-regulated miRNAs in cancers. A predominant repression effect on miRNA expression was found for mutant p53, with 183 significantly downregulated and only 12 upregulated miRNAs. Mutp53 and wild-type (wtp53) commonly upregulate let-7i, and other two miRNAs were upregulated by wtp53 but repressed by mutp53 (miR-610 and miR-3065-3p). Based the mutp53-regulated miRNA signature, a non-negative matrix factorization (NMF) model classified gastric cancer (GC) cases into subgroups with significantly different Disease-free survival (Kaplan-Meier test, P = 0.013). In contrast, the NMF model based on all miRNAs did not associate with cancer outcome. The mutp53 miRNA signature associated with the outcomes of breast cancer (P = 0.024) and hepatocellular cancer (P = 0.012). The miRPath analysis revealed that mutp53-suppressed miRNAs associate with Hippo, TGF-β and stem cell signaling pathways. Taken together, our results highlight a miRNA-mediated GOF mechanism of mutant p53 on Arg282, and suggest the prognostic potential of mutp53-associated miRNA signature. PMID:26840456

    Primary Hepatic Carcinoid Tumor (PHCT) represents an extremely rare clinical entity with only a few cases reported to date. These tumors are rarely associated with metastasis and surgical resection is usually curative. Herein, we report two cases of PHCT associated with poor outcomes due to late diagnosis. Both cases presented late with non-specific symptoms. One patient presented after a 2-week history of symptoms and the second case had a longstanding two years symptomatic interval during which he remained undiagnosed and not properly worked up. Both these cases were diagnosed with hepatic carcinoid tumor, which originates from neuroendocrine cells. Case 1 opted for palliative care and expired in one month’s time. Surgical resection was advised to the second case, but he left against medical advice. PMID:26975959

    We investigated the association between smoking and the disease activity, functional ability, physical mobility, and systemic inflammation in Chinese ankylosing spondylitis (AS) patients. Seventy five male Chinese AS patients in Taiwan were enrolled in the cross-sectional study. These patients fulfilled the 1984 modified New York criteria. Patients completed the questionnaires, containing the demographic data, disease activity, functional ability (BASFI), and patient's global assessment. Meanwhile, physical examinations were performed to determine the patient's physical mobility. Acute-phase reactants, erythrocyte sedimentation rate (ESR), and C-reactive protein levels were also measured in the AS patients. Smoking habits with smoking duration and smoking intensity (pack-years of smoking) were recorded. Among these physical mobility parameters, modified Schober's index (p < 0.001), cervical rotation (p = 0.034), later lumbar flexion (p = 0.002), chest expansion (p = 0.016), and occiput-to-wall distances (p = 0.003) were significantly impaired in smoking AS patients (n = 35) as compared to non-smoking (n = 40). Systemic inflammation parameter, ESR was significantly higher in smoking AS patients than non-smoking (p = 0.03). The odds ratio of advanced modified Schober's index, lateral lumbar flexion, fingertip-to-floor distance, chest expansion, and occiput-to-wall were significantly elevated in smoking AS patients as compared to non-smoking. Moreover, the smoking intensity correlated significantly with BASFI (r = 0.481, p = 0.005), cervical rotation (r = -0.401, p = 0.031), fingertip-to-floor distance (r = 0.485, p = 0.004), and occiput-to-wall distance (r = 0.473, p = 0.005) in the 35 smoking AS patients. The cigarette smokers in the Chinese AS patients have increased systemic inflammation and poor physical mobility. In addition, the higher smoking intensity in the AS smokers is associated with poor disease outcome, including functional ability and physical mobility

    In spite of significant advances in treatment of patients with schizophrenia and continued efforts towards their deinstitutionalization, a considerable group of patients remain chronically hospitalized or otherwise dependent on others for basic necessities of life. It has been proposed that these patients belong to a distinct etiopathological subgroup, termed Kraepelinian, whose course of illness may be progressive and resistant to treatment. Indeed, longitudinal studies appear to show that elderly Kraepelinian patients follow a course of rapid cognitive and functional deterioration, commensurate with a dementing process, and that their poor functional status is closely correlated with the cognitive deterioration. Recent neuroimaging studies described a pattern of posteriorization of grey and white matter deficits with poor outcome in schizophrenia, and produced a constellation of findings implicating primary processing of visual and auditory information as central to the impaired functional status in this patient group. These studies are summarized in detail in this review and future directions for neuroimaging assessment of very poor outcome patients with schizophrenia are suggested. PMID:17671868

    Background: Family members and caregivers may misinterpret blunted affect as a true lack of emotion in patients with schizophrenia. Aim: To assess felt affect or experienced emotion among low- and high-functioning schizophrenics. Methods: Two hundred people with schizophrenia were assessed using the Global Assessment of Functioning scale of DSM-IV and the Positive and Negative Affect Schedule (PANAS). Results: The findings reveal that people with good- and poor-outcome schizophrenia show no significant differences in the emotions experienced, implying that felt affect is comparable regardless of the severity of symptoms in chronic schizophrenia. In fact, low-functioning patients scored a mean (SD) of 46.07 (13.13) on the PANAS, in contrast to a slightly lower scored by high-functioning patients (44.33 [12.03]). Conclusion: Although patients may show flat affect, and therefore be mistakenly considered withdrawn and apathetic by the observer, they do, in fact, experience as much, or perhaps even more emotion than their higher-functioning counterparts.

    The Medline database was searched using key words: 'rotator cuff', 'tear', and 'treatment'. 12 studies that involved (1) surgical treatment for rotator cuff tear, (2) measurement of pre- and post-operative pain score, functional score, and/or patient satisfaction, (3) patients that failed to improve functionally or had poor satisfaction, (4) preoperative examination of risk factors that could lead to poor outcome, and (5) a minimum follow-up of 6 months were reviewed to identify risk factors associated with poor outcome following surgical treatment for rotator cuff tear. The most common risk factor was tear size, followed by open compensation claim, age, and time from injury to surgery. PMID:27574276

    Heart failure (HF) has reached epidemic proportions and is a significant contributor to poor outcomes. HF is an established risk factor for Alzheimer's disease, vascular dementia, and abnormalities on neuroimaging. Moreover, up to 80% of HF patients also exhibit milder impairments on cognitive tests assessing attention, executive function, memory, and language. The mechanisms of cognitive impairment in HF are not entirely clear and involve a combination of physiological processes that negatively impact the brain. Cerebral hypoperfusion and common comorbid conditions in HF are among the most commonly proposed contributors to poor neurocognitive outcomes in this population. Obesity is another likely risk factor for adverse brain changes and cognitive impairment in HF, as it is a known contributor to neurocognitive outcomes in healthy and patient samples. This paper reviews the literature on HF and cognitive function and introduces obesity as a significant risk factor for poor neurocognitive outcomes in this population. PMID:23743688

    Background Neurologic deterioration (ND) after acute ischemic stroke (AIS) has been shown to result in poor outcomes. ND is thought to arise from penumbral excitotoxic cell death caused in part by leukocytic infiltration. Elevated admission peripheral leukocyte levels are associated with poor outcomes in stroke patients who suffer ND, but little is known about the dynamic changes that occur in leukocyte counts around the time of ND. We sought to determine if peripheral leukocyte levels in the days surrounding ND are correlated with poor outcomes. Methods Patients with AIS who presented to our center within 48 hours of symptom onset between July 2008 and June 2010 were retrospectively identified by chart review and screened for ND (defined as an increase in National Institutes of Health Stroke Scale score ≥2 within a 24-hour period). Patients were excluded for steroid use during hospitalization or in the month before admission and infection within the 48 hours before or after ND. Demographics, daily leukocyte counts, and poor functional outcome (modified Rankin Scale score 3–6) were investigated. Results Ninety-six of the 292 (33%) patients screened had ND. The mean age was 69.5 years; 62.5% were male and 65.6% were black. Patients with a poor functional outcome had significantly higher leukocyte and neutrophil levels 1 day before ND (P =.048 and P =.026, respectively), and on the day of ND (P =.013 and P =.007, respectively), compared to patients with good functional outcome. Conclusions Leukocytosis at the time of ND correlates with poor functional outcomes and may represent a marker of greater cerebral damage through increased parenchymal inflammation. PMID:23031742

    Discrete risk factors for poor outcomes in childhood epilepsy have been identified, but it is unclear whether the combined effect of several risk factors better predicts outcome. The Epilepsy Cumulative Risk Scale was developed to quantify cumulative risk for poor outcomes in childhood epilepsy. Participants included 156 clinic-referred children with epilepsy. The Epilepsy Cumulative Risk Scale was developed using variables previously associated with functional outcomes. Scale utility was examined through its association with intellectual and academic functioning. All Epilepsy Cumulative Risk Scale variables were significantly associated with functioning. The Total Score (ie, cumulative effect) was most strongly correlated with cognition and academic skills. A Total Score ≥ 5 had the best sensitivity and specificity for differentiating those at high risk for poor outcomes. The Epilepsy Cumulative Risk Scale shows promise as a practical, data-driven tool for quantification of cumulative risk for poor outcomes in childhood epilepsy and may be helpful in detecting those needing referral for additional services.

    The purpose was to compare the outcome of patients with radiation-induced constrictive pericarditis versus patients with constiction due to another etiology. Twenty patients with constrictive pericarditis were seen during 1975-1986 at a single medical center. Six had radiation-induced constrictive pericarditis (Group A). The etiology was idiopathic in ten subjects and secondary to carcinomatous encasement, chronic renal failure, purulent infection and tuberculosis in one patient each (Group B, N = 14). Meang age was 53.4 [+-] 15.5 years. Extensive pericardiectomy was performed in 3/6 Group A and 13/14 Group B patients. All Group A patients died, 4 weeks - 11 years post-diagnosis (median = 10 months). Two Group A patients died suddenly, one died post-operatively of respiratory failure, another of pneumonia and two of recurrent carcinoma. Thirteen Group B patients are alive (median follow-up = 72 months). The only death in this group was due to metastatic cancer. The poor outcome with radiation-induced constriction is probably multi-factorial. Poor surgical outcome is to be expected in patients with evidence of recurrent tumor, high-dose irradiation, pulmonary fibrosis or associated radiation-induced myocardinal, valvular or coronary damage.

    This paper investigated whether greater tree-canopy cover is associated with reduced risk of poor birth outcomes in Portland, Oregon. Residential addresses were geocoded and linked to classified-aerial imagery to calculate tree-canopy cover in 50, 100, and 200 m buffers around each home in our sample (n=5696). Detailed data on maternal characteristics and additional neighborhood variables were obtained from birth certificates and tax records. We found that a 10% increase in tree-canopy cover within 50 m of a house reduced the number of small for gestational age births by 1.42 per 1000 births (95% CI-0.11-2.72). Results suggest that the natural environment may affect pregnancy outcomes and should be evaluated in future research. PMID:21106432

    Engraftment syndrome (ES), characterized by fever, rash, pulmonary edema, weight gain, liver and renal dysfunction, and/or encephalopathy, occurs at the time of neutrophil recovery after hematopoietic cell transplantation (HCT). In this study, we evaluated the incidence, clinical features, risk factors, and outcomes of ES in children and adults undergoing first-time allogeneic HCT. Among 927 patients, 119 (13%) developed ES at a median of 10 days (interquartile range 9 to 12) after HCT. ES patients experienced significantly higher cumulative incidence of grade 2 to 4 acute GVHD at day 100 (75% versus 34%, P < .001) and higher nonrelapse mortality at 2 years (38% versus 19%, P < .001) compared with non-ES patients, resulting in lower overall survival at 2 years (38% versus 54%, P < .001). There was no significant difference in relapse at 2 years (26% versus 31%, P = .772). Suppression of tumorigenicity 2, interleukin 2 receptor alpha, and tumor necrosis factor receptor 1 plasma biomarker levels were significantly elevated in ES patients. Our results illustrate the clinical significance and prognostic impact of ES on allogeneic HCT outcomes. Despite early recognition of the syndrome and prompt institution of corticosteroid therapy, outcomes in ES patients were uniformly poor. This study suggests the need for a prospective approach of collecting clinical features combined with correlative laboratory analyses to better characterize ES. PMID:24892262

    Background While there are many psychophysical reports of impaired magnocellular pathway function in developmental dyslexia (DD), few have investigated parietal function, the major projection of this pathway, in good and poor readers closely matched for nonverbal intelligence. In view of new feedforward-feedback theories of visual processing, impaired magnocellular function raises the question of whether all visually-driven functions or only those associated with parietal cortex functions are equally impaired and if so, whether parietal performance is more closely related to general ability levels than reading ability. Methods Reading accuracy and performance on psychophysical tasks purported to selectively activate parietal cortex such as motion sensitivity, attentional tracking, and spatial localization was compared in 17 children with DD, 16 younger reading-age matched (RA) control children, and 46 good readers of similar chronological-age (CA) divided into CA-HighIQ and a CA-LowIQ matched to DD group nonverbal IQ. Results In the age-matched groups no significant differences were found between DD and CA controls on any of the tasks relating to parietal function, although performance of the DD group and their nonverbal IQ scores was always lower. As expected, CA and RA group comparisons indicated purported parietal functioning improves with age. No difference in performance was seen on any of the parietally driven tasks between the DD and age-nonverbal IQ matched groups, whereas performance differentiated the DD group from the age-matched, higher nonverbal IQ group on several such tasks. An unexpected statistical difference in performance between lower reading age (DD and RA children) and all higher reading age (CA) children was seen on a test of chromatic sensitivity, whereas when high and low nonverbal IQ normal readers were compared performance was not different Conclusion The results indicate that performance on purported parietal functions improves with age

    Aims To evaluate phenotypic and genetic variables associated with a poor long-term response to inhaled corticosteroid therapy for asthma, based independently on lung function changes or asthma exacerbations. Materials & methods We tested 17 phenotypic variables and polymorphisms in FCER2 and CRHR1 in 311 children (aged 5–12 years) randomized to a 4-year course of inhaled corticosteroid during the Childhood Asthma Management Program (CAMP). Results Predictors of recurrent asthma exacerbations are distinct from predictors of poor lung function response. A history of prior asthma exacerbations, younger age and a higher IgE level (p < 0.05) are associated with recurrent exacerbations. By contrast, lower bronchodilator response to albuterol and the minor alleles of RS242941 in CRHR1 and T2206C in FCER2 (p < 0.05) are associated with poor lung function response. Poor lung function response does not increase the risk of exacerbations and vice versa (p = 0.72). Conclusion Genetic and phenotypic predictors of a poor long-term response to inhaled corticosteroids differ markedly depending on definition of outcome (based on exacerbations vs lung function). These findings are important in comparing outcomes of clinical trials and in designing future pharmacogenetic studies. PMID:19663668

    Objective We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. Methods A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were calculated. Outcome was defined as excellent, good, fair, and poor based on Mcnab classification. The percentage of superior facetectomy was calculated by using the Maro-view 5.4 Picture Archiving Communication System (PACS). Results Paramedian lumbar discectomy was performed in 180 patients and combined lumbar discectomy was performed in 54 patients. Paramedian lumbar discectomy group showed better outcome compared with combined discectomy group. p value of VAS change was 0.009 and KODI was 0.013. The average percentage of superior facetectomy was 33% (range, 0–79%) and it showed negative correlation with VAS and KODI changes (Pearson coefficient : -0.446 and -0.498, respectively). Excellent or good outcome cases (Group I) were 136 (58.1%) and fair or poor outcome cases (Group II) were 98 (41.9%). The percentage of superior facetectomy was 26.5% at Group I and 42.5% at Group II. There was significant difference in superior facetectomy percentage between Group I and II (p=0.000). Conclusion This study demonstrated that paramedian lumbar discectomy with preservation of facet joints is an effective and good procedure for FELDH. At least 60% of facet should be preserved for excellent or good outcomes. PMID:26962420

    Background Driving is a common part of modern society, but its potential effects on health are not well understood. Purpose The present cross-sectional study (n = 37,570) examined the associations of driving time with a series of health behaviors and outcomes in a large population sample of middle-aged and older adults using data from the Social, Economic, and Environmental Factor Study conducted in New South Wales, Australia, in 2010. Methods Multiple logistic regression was used in 2013 to examine the associations of usual daily driving time with health-related behaviors (smoking, alcohol use, diet, physical activity, sedentary behavior, sleep) and outcomes (obesity, general health, quality of life, psychological distress, time stress, social functioning), adjusted for socio-demographic characteristics. Results Findings suggested that longer driving time was associated with higher odds for smoking, insufficient physical activity, short sleep, obesity, and worse physical and mental health. The associations consistently showed a dose-response pattern and more than 120 minutes of driving per day had the strongest and most consistent associations with the majority of outcomes. Conclusion This study highlights driving as a potential lifestyle risk factor for public health. More population-level multidisciplinary research is needed to understand the mechanism of how driving affects health. PMID:24911017

    Background and Purpose The functional recovery after the lateral medullary infarction (LMI) is usually good. Little is known about the prognostic factors associated with poor outcome following acute LMI. The aim of this study was to identify the factors associated with poor long-term outcome after acute LMI, based on experiences at a single center over 11 years. Methods A consecutive series of 157 patients with acute LMI who were admitted within 7 days after symptom onset was evaluated retrospectively. Clinical symptoms were assessed within 1 day after admission, and outcomes were evaluated over a 1-year period after the initial event. The lesions were classified into three vertical types (rostral, middle, and caudal), and the patients were divided into two groups according to the outcome at 1 year: favorable [modified Rankin Scale (mRS) score ≤1] and unfavorable (mRS score ≥2). Results Of the 157 patients, 93 (59.2%) had a favorable outcome. Older age, hypertension, dysphagia, requirement for intensive care, and pneumonia were significantly more prevalent in the unfavorable outcome group. The frequencies of intensive care (13%) and mortality (16.7%) were significantly higher in the rostral lesion (p=0.002 and p=0.002). Conditional logistic regression analysis revealed that older age and initial dysphagia were independently related to an unfavorable outcome at 1 year [odds ratio (OR)=1.04, 95% confidence interval (95% CI)=1.001-1.087, p=0.049; OR=2.46, 95% CI=1.04-5.84, p=0.041]. Conclusions These results suggest that older age and initial dysphagia in the acute phase are independent risk factors for poor long-term prognosis after acute LMI. PMID:26256660

    Compared to younger patients, traumatic injury in older patients is associated with increased mortality and a range of adverse outcomes such as higher rates of infectious episodes, longer length of hospital stay and poor functional outcome at follow up. Data emerging from human and murine-based studies suggest age-related changes in immune function, collectively termed immunesenescence, and the chronic sub-clinical systemic inflammatory state of older adults, termed inflammaging, may contribute to these poor outcomes. Here, we review the findings of these studies, whose results demonstrate that the geriatric trauma patient elicits an immune response to injury that is distinct to that of younger adults, being characterised by reduced immune cell activation, impaired function and abnormal haematopoiesis, defects that are accompanied by an altered inflammatory response that fails to return to a homeostatic baseline in the days following injury. Although considerable evidence is accumulating that demonstrates clear and significant age-related differences in the immune and inflammatory response to traumatic injury, our current understanding of the mechanism(s) that underlie these changes is limited. Future studies that provide a mechanistic explanation for the unique immune and inflammatory response of older adults to traumatic injury are therefore essential if we are to determine whether manipulation of the immune system has potential as a future therapeutic strategy by which to improve the outcome of the geriatric trauma patient.

    Many patients with schizophrenia have poor clinical and social outcomes. Some risk alleles closely related to the onset of schizophrenia have been reported to be associated with their clinical phenotypes, but the direct relationship between genetic vulnerability to schizophrenia and clinical/social outcomes of schizophrenia, as evaluated by both practical clinical scales and 'real-world' function, has not been investigated. We evaluated the clinical and social outcomes of 455 Japanese patients with schizophrenia by severity of illness according to the Clinical Global Impression-Severity Scale (CGI-S) and social outcomes by social adjustment/maladjustment at 5 years after the first visit. We examined whether 46 single nucleotide polymorphisms (SNPs) selected from a Japanese genome-wide association study of susceptibility to schizophrenia were associated with clinical and social outcomes. We also investigated the polygenic risk scores of 46 SNPs. Allele-wise association analysis detected three SNPs, including rs2623659 in the CUB and Sushi multiple domains-1 (CSMD1) gene, associated with severity of illness at end point. The severity of illness at end point was associated with treatment response, but not with the severity of illness at baseline. Three SNPs, including rs2294424 in the C6orf105 gene, were associated with social outcomes. Point estimates of odds ratios showed positive relationships between polygenic risk scores and clinical/social outcomes; however, the results were not statistically significant. Because these results are exploratory, we need to replicate them with a larger sample in a future study. PMID:26674612

    Background and Purpose Low-density lipoprotein (LDL) particle size is considered to be one of the more important cardiovascular risk factors, and small LDL particles are known to have atherogenic potential. The aim of this study was to determine whether LDL particle size is associated with stroke severity and functional outcome in patients with atherothrombotic stroke. Methods Between January 2009 and May 2011, 248 patients with first-episode cerebral infarction who were admitted to our hospital within 7 days after symptom onset were prospectively enrolled. LDL particle size was measured using the nondenaturing polyacrylamide gradient gel electrophoresis assay. Stroke severity was assessed by applying the National Institutes of Health Stroke Scale (NIHSS) at admission. Functional outcome was investigated at 3 months after the index stroke using the modified Rankin Scale (mRS), and poor functional outcome was defined as an mRS score of ≥3. Results The LDL particle size in the 248 patients was 25.9±0.9 nm (mean±SD). LDL particle size was inversely correlated with the degree of cerebral artery stenosis (p=0.010). Multinomial multivariate logistic analysis revealed that after adjustment for age, sex, and variables with p<0.1 in univariate analysis, LDL particle size was independently and inversely associated with stroke severity (NIHSS score ≥5; reference, NIHSS score 0-2; odds ratio=0.38, p=0.028) and poor functional outcome (odds ratio=0.44, p=0.038). Conclusions The results of this study demonstrate that small LDL particles are independently correlated with stroke outcomes. LDL particle size is thus a potential biomarker for the prognosis of atherothrombotic stroke. PMID:25628741

    Atopic dermatitis (AD) is a chronic relapsing inflammatory disease of the skin and is the most common paediatric dermatological condition. While no cure is available, it can be treated effectively if adherence to a therapeutic plan is maintained. Poor adherence to treatment is common in AD and can lead to treatment failure, which has significant impacts on the patient, family and society. A comprehensive literature search was conducted to identify factors that contribute to poor treatment adherence in childhood AD and to identify possible strategies to remedy these. Identified factors leading to poor treatment adherence include: complexity of treatment regimen, lack of knowledge, impaired quality of life, dissatisfaction with treatment strategies, infrequent follow up, corticosteroid phobia and the use of complementary and alternative medicine. Effective strategies to increase treatment adherence include: caregiver education and utilisation of education adjuncts, optimisation of the patient/caregiver-clinician relationship, early and frequent follow up and improvement of patient and caregiver quality of life.

    In this study we examined the relationship between premorbid functioning, outcome, cognitive functioning and positive and negative symptoms of schizophrenia. Cognitive functioning and symptoms were examined longitudinally in a sample of 39 subjects with schizophrenia (according to the DSM-III criteria). Subjects were assessed at admission to hospital and six months later during a period of relative remission. Premorbid functioning was significantly associated with negative symptoms but not with positive symptoms at both the acute phase and the remitted phase of the illness. Outcome was also associated with negative symptoms at admission and with both positive and negative symptoms at follow-up. Deficits on cognitive tests of verbal reasoning and concept formation were significantly associated with poor premorbid functioning and outcome. PMID:8461276

    Clinical outcomes for high-risk neuroblastoma patients remains poor, with only 40–50% 5-Year overall survival (OS) and <10% long-term survival. The ongoing acquisition of genetic/molecular rearrangements in undifferentiated neural crest cells may endorse neuroblastoma progression. This study recognized the loss of Retinal Degeneration protein 3, RD3 in aggressive neuroblastoma, and identified its influence in better clinical outcomes and defined its novel metastasis suppressor function. The results showed ubiquitous expression of RD3 in healthy tissues, complete-loss and significant TNM-stage association of RD3 in clinical samples. RD3-loss was intrinsically associated with reduced OS, abridged relapse-free survival, aggressive stage etc., in neuroblastoma patient cohorts. RD3 was transcriptionally and translationally regulated in metastatic site-derived aggressive (MSDAC) cells (regardless of CSC status) ex vivo and in tumor manifolds from metastatic sites in reproducible aggressive disease models in vivo. Re-expressing RD3 in MSDACs reverted their metastatic potential both in vitro and in vivo. Conversely muting RD3 in neuroblastoma cells not only heightened invasion/migration but also dictated aggressive disease with metastasis. These results demonstrate the loss of RD3 in high-risk neuroblastoma, its novel, thus-far unrecognized metastasis suppressor function and further imply that RD3-loss may directly relate to tumor aggressiveness and poor clinical outcomes.

    The diagnosis of schizophrenia can only be made in the presence of a loss of functioning in domains such as employment, independent living, and social functioning. Accurately measuring functioning is central to research on the course of the disorder, treatment and rehabilitation outcomes, and biosocial factors in schizophrenia. Assessments of functional disability have described three dimensions of functioning: functional capacity, functional performance, and functional outcome. The "competence/performance" distinction refers to the observation that an individual may demonstrate an ability to perform a functional task (capacity) but may not do so in her own community environment (performance). Functional outcomes are the result of both capacity and performance. Several recent reviews have compared the characteristics, reliability, and validity of various functional assessment instruments. Two major initiatives are underway to gather additional comparative data about functional assessment strategies. Recently, both the recovery movement and the recognition of the role of environmental factors in functioning have raised questions about the conceptual content of the functioning construct (construct validity). For instance, several studies have demonstrated that features of functioning need not track together over the course of the illness. In addition, the notion of recovery emphasizes processes like community integration and subjective well-being that are not static outcomes but are continually evolving features of the life course in chronic illness. Findings on the dynamic role of environmental moderators such as support and opportunity also present challenges to scientific constructs. For these reasons and others, the ecological validity of functional assessments has become a central concern. Both the verisimilitude and veridicality of functional assessments can be empirically assessed, but to date very few studies have measured the extent to which functional

    Background: Tumors arising from cerebellar peduncle are extremely rare and behave aggressively. The inclusion of these into either cerebellar or brainstem gliomas is contentious. Case Description: We performed clinicopathological review of three patients treated at our institute and surveyed the literature for previous such reported cases. Mean duration of symptoms in our patients was 2 weeks. Subtotal tumor resection was performed in two patients while the third underwent stereotactic biopsy followed by chemoradiotherapy. Histopathology revealed glioblastoma in initial two patients and medulloblastoma Grade IV in the third. The two patients who underwent surgical excision succumbed to the illness within 2 days and a month, respectively. Conclusion: Malignant cerebellar peduncular lesions have poor overall survival despite surgical debulking. It is not confirmed whether these tumors should be considered as cerebellar lesions or brainstem gliomas due to aggressive clinical behavior, and so the ideal line of management is not yet known.

    Rationale: Poor adherence to asthma controller medications results in poor treatment outcomes. Objectives: To compare controller medication adherence and clinical outcomes in 612 adults with poorly controlled asthma randomized to one of two different treatment decision-making models or to usual care. Methods: In shared decision making (SDM), nonphysician clinicians and patients negotiated a treatment regimen that accommodated patient goals and preferences. In clinician decision making, treatment was prescribed without specifically eliciting patient goals/preferences. The otherwise identical intervention protocols both provided asthma education and involved two in-person and three brief phone encounters. Measurements and Main Results: Refill adherence was measured using continuous medication acquisition (CMA) indices—the total days' supply acquired per year divided by 365 days. Cumulative controller medication dose was measured in beclomethasone canister equivalents. In follow-up Year 1, compared with usual care, SDM resulted in: significantly better controller adherence (CMA, 0.67 vs. 0.46; P < 0.0001) and long-acting β-agonist adherence (CMA, 0.51 vs. 0.40; P = 0.0225); higher cumulative controller medication dose (canister equivalent, 10.9 vs. 5.2; P < 0.0001); significantly better clinical outcomes (asthma-related quality of life, health care use, rescue medication use, asthma control, and lung function). In Year 2, compared with usual care, SDM resulted in significantly lower rescue medication use, the sole clinical outcome available for that year. Compared with clinician decision making, SDM resulted in: significantly better controller adherence (CMA, 0.67 vs. 0.59; P = 0.03) and long-acting β-agonist adherence (CMA, 0.51 vs. 0.41; P = 0.0143); higher cumulative controller dose (CMA, 10.9 vs. 9.1; P = 0.005); and quantitatively, but not significantly, better outcomes on all clinical measures. Conclusions: Negotiating patients' treatment decisions

    Objectives To assess the association between plasma homocysteine (Hcy), blood pressure (BP) and poor outcome at hospital discharge among acute ischemic stroke patients, and if high Hcy increases the risk of poor outcome based on high BP status in a northern Chinese population. Methods Between June 1, 2009 and May 31, 2013, a total of 3695 acute ischemic stroke patients were recruited from three hospitals in northern Chinese cities. Demographic characteristics, lifestyle risk factors, medical history, and other clinical characteristics were recorded for all subjects. Poor outcome was defined as a discharge modified Rankin Scale (mRS) score ≥3 or death. The association between homocysteine concentration, admission blood pressure, and risk of poor outcome following acute ischemic stroke was analyzed by using multivariate non-conditional logistic regression models. Results Compared with those in the lowest quartile of Hcy concentration in a multivariate-adjusted model, those in the highest quartile of Hcy concentration had increased risk of poor outcome after acute ischemic stroke, (OR = 1.33, P<0.05). The dose-response relationship between Hcy concentration and risk of poor outcome was statistically significant (p-value for trend  = 0.027). High BP was significantly associated with poor outcome following acute ischemic stroke (adjusted OR = 1.44, 95%CI, 1.19–1.74). Compared with non-high BP with nhHcy, in a multivariate-adjusted model, the ORs (95% CI) of non-high BP with hHcy, high BP with nhHcy, and high BP with hHcy to poor outcome were 1.14 (0.85–1.53), 1.37 (1.03–1.84) and 1.70 (1.29–2.34), respectively. Conclusion The present study suggested that high plasma Hcy and blood pressure were independent risk factors for prognosis of acute ischemic stroke, and hHcy may further increase the risk of poor outcome among patients with high blood pressure. Additionally, the results indicate that high Hcy with high BP may cause increased susceptibility

    Chronic subdural hematoma (CSDH) has been recognized as a benign disease, but its clinical outcome is not well documented. This study aims to expand the knowledge base regarding the outcome of CSDH. We retrospectively reviewed clinical characteristics of CSDH operated in the Kobe City Medical Center General Hospital between June 2005 and June 2012. Variants included age at onset, sex, laterality, presence of headache, consciousness level, and risk factors for hemorrhage such as malignancy or intake of anticoagulants. A total of 368 cases were analyzed. Six patients (1.4%) had a poor outcome, defined as any morbidity or mortality at 7 days postoperatively. Bilateral hematoma was significantly associated with a poor outcome (p = 0.041). Warfarin use and malignancy, albeit statistically not significant, were more frequently observed in patients with a poor outcome. Bilateral CSDH was observed in 53 patients (14.4%). Age at onset, sex, history of malignancy, anticoagulant use, and antiplatelet use did not differ between bilateral and unilateral CSDH. Recurrence rate was not different between bilateral and unilateral CSDH (14.2% vs. 11.3%), but poor outcome as a result of brain herniation was significantly higher in bilateral than in unilateral hematomas (5.7% vs. 0.3%, p = 0.01). Bilateral CSDH was associated with rapid progression and showed worse outcome as a result of brain herniation in comparison with unilateral CSDH. Urgent trephination surgery for decompression of hematoma pressure may be recommended for bilateral CSDH. PMID:26923835

    In this study we provide a compilation of functional impairments before and improvements after face transplantation (FT) of five FT recipients of our institution and all FTs reported in current literature. Functional outcome included the ability to smell, breath, eat, speak, grimace and facial sensation. Before FT, all our patients revealed compromised ability to breath, eat, speak, grimace and experience facial sensation. The ability to smell was compromised in two of our five patients. Two patients were dependent on tracheostomy and one on gastrostomy tubes. After FT, all abilities were significantly improved and all patients were independent from artificial air airways and feeding tubes. Including data given in current literature about the other 24 FT recipients in the world, the abilities to smell, eat and feel were enhanced in 100% of cases, while the abilities of breathing, speaking and facial expressions were ameliorated in 93%, 71% and 76% of cases, respectively. All patients that required gastrostomy and 91% of patients depending on tracheostomy were decannulated after FT. Unfortunately, outcomes remain unreported in all other cases and therefore we are unable to comment on improvements. PMID:25359281

    Background and Purpose Chronic kidney disease (CKD) is an established risk factor for numerous cardiovascular diseases including stroke. The relationship between the baseline estimated glomerular filtration rate (eGFR) and clinical 3-month outcomes in patients with acute ischemic stroke were evaluated in this study. Methods This was a prospective cohort study involving a hospital-based stroke registry; 1373 patients with acute ischemic stroke were enrolled. Patients were divided into the following four groups according their eGFR (calculated using the CKD Epidemiology Collaboration equations): ≥60, 45-59, 30-44, and <30 mL/min/1.73 m2. The primary endpoint of poor functional outcome was defined as 3-month death or dependency (modified Rankin Scale score ≥3); secondary endpoints were neurological deterioration (increase in National Institutes of Health Stroke Severity score of ≥4 at discharge compared to baseline) during hospitalization and in-hospital mortality. Results The overall eGFR was 84.5±20.8 mL/min/1.73 m2 (mean±SD). The distribution of baseline renal impairment was as follows: 1,218, 82, 40, and 33 patients had eGFRs of ≥60, 45-59, 30-44, and <30 mL/min/1.73 m2, respectively. At 3 months after the stroke, 476 (34.7%) patients exhibited poor functional outcome. Furthermore, a poor functional outcome occurred more frequently with increasingly advanced stages of CKD (rates of 31.9%, 53.7%, 55.0%, and 63.6% for CKD stages 1/2, 3a, 3b, and 4/5, respectively; p<0.001). Multivariate analysis revealed that a baseline eGFR of <30 mL/min/1.73m2 increased the risk of a poor functional outcome by 2.37-fold (p=0.047). In addition, baseline renal dysfunction was closely associated with neurological deterioration during hospitalization and with in-hospital mortality. Conclusions A low baseline eGFR was strongly predictive of both poor functional outcome at 3 months after ischemic stroke and neurological deterioration/mortality during hospitalization. PMID

    2016-01-01

    Objective To identify the factors that could predict the functional outcome in patients with the axonal type of Guillain-Barre syndrome (GBS). Methods Two hundred and two GBS patients admitted to our university hospital between 2003 and 2014 were reviewed retrospectively. We defined a good outcome as being "able to walk independently at 1 month after onset" and a poor outcome as being "unable to walk independently at 1 month after onset". We evaluated the factors that differed between the good and poor outcome groups. Results Twenty-four patients were classified into the acute motor axonal neuropathy type. There was a statistically significant difference between the good and poor outcome groups in terms of the GBS disability score at admission, and GBS disability score and Medical Research Council sum score at 1 month after admission. In an electrophysiologic analysis, the good outcome group showed greater amplitude of median, ulnar, deep peroneal, and posterior tibial nerve compound muscle action potentials (CMAP) and greater amplitude of median, ulnar, and superficial peroneal sensory nerve action potentials (SNAP) than the poor outcome group. Conclusion A lower GBS disability score at admission, high amplitude of median, ulnar, deep peroneal, and posterior tibial CMAPs, and high amplitude of median, ulnar, and superficial peroneal SNAPs were associated with being able to walk at 1 month in patients with axonal GBS.

    Abstract This study aimed to determine the prevalence and predictors of poor 3 and 12 month quality of life outcomes in a cohort of pediatric patients with isolated mild TBI. We conducted a prospective cohort study of children and adolescents <18 years of age treated for an isolated mild TBI, defined as “no radiographically apparent intracranial injury” or “an isolated skull fracture, and no other clinically significant non-brain injuries.” The main outcome measure was the change in quality of life from baseline at 3 and 12 months following injury, as measured by the Pediatric Quality of Life index (PedsQL). Poor functioning was defined as a decrease in total PedsQL score of >15 points between baseline and follow-up scores (at 3 and 12 months). Of the 329 patients who met inclusion criteria, 11.3% (95% CI 8.3–15.3%) at 3 months and 12.9% (95% CI 9.6–17.2%) at 12 months following injury had relatively poor functioning. Significant predictors of poor functioning included less parental education, Hispanic ethnicity (at 3 months following injury, but not at 12 months); low household income (at 3 and 12 months), and Medicaid insurance (at 12 months only). Children and adolescents sustaining a mild TBI who are socioeconomically disadvantaged may require additional intervention to mitigate the effects of mild TBI on their functioning. PMID:24294826

    The literature on whether students with disabilities have worse physical and mental health, social adjustment, and participation outcomes when compared to their peers without disabilities is largely inconclusive. While the majority of case control studies showed significantly worse outcomes for students with disabilities; the proportion of variance accounted for is rarely reported. The current study used a population cross-sectional approach to determine the classification ability of commonly used screening and outcome measures in determining the disability status. Furthermore, the study aimed to identify the variables, if any, that best predicted the presence of disability. Results of univariate discriminant function analyses suggest that across the board, the sensitivity of the outcome/screening tools to correctly identify students with a disability was 31.9% higher than the related Positive Predictive Value (PPV). The lower PPV and Positive Likelihood Ratio (LR+) scores suggest that the included measures had limited discriminant ability (17.6% to 40.3%) in accurately identifying students at-risk for further assessment. Results of multivariate analyses suggested that poor health and hyperactivity increased the odds of having a disability about two to three times, while poor close perceived friendship and academic competences predicted disability with roughly the same magnitude. Overall, the findings of the current study highlight the need for researchers and clinicians to familiarize themselves with the psychometric properties of measures, and be cautious in matching the function of the measures with their research and clinical needs.

    Abstract Cochlear implantation is currently the treatment of choice for children with severe to profound hearing impairment. However, the outcomes with cochlear implants (CIs) vary significantly among recipients. The purpose of the present study is to identify the genetic determinants of poor CI outcomes. Twelve children with poor CI outcomes (the “cases”) and 30 “matched controls” with good CI outcomes were subjected to comprehensive genetic analyses using massively parallel sequencing, which targeted 129 known deafness genes. Audiological features, imaging findings, and auditory/speech performance with CIs were then correlated to the genetic diagnoses. We identified genetic variants which are associated with poor CI outcomes in 7 (58%) of the 12 cases; 4 cases had bi-allelic PCDH15 pathogenic mutations and 3 cases were homozygous for the DFNB59 p.G292R variant. Mutations in the WFS1, GJB3, ESRRB, LRTOMT, MYO3A, and POU3F4 genes were detected in 7 (23%) of the 30 matched controls. The allele frequencies of PCDH15 and DFNB59 variants were significantly higher in the cases than in the matched controls (both P < 0.001). In the 7 CI recipients with PCDH15 or DFNB59 variants, otoacoustic emissions were absent in both ears, and imaging findings were normal in all 7 implanted ears. PCDH15 or DFNB59 variants are associated with poor CI performance, yet children with PCDH15 or DFNB59 variants might show clinical features indistinguishable from those of other typical pediatric CI recipients. Accordingly, genetic examination is indicated in all CI candidates before operation. PMID:26166082

    Study Design Retrospective Cohort Introduction Pollicization creates a thumb from another finger to treat hypoplasia/aplasia. Important outcomes include strength, function, dexterity, and quality of life. Purpose of the Study To evaluate mid- to long-term outcomes and examine predictors of outcome after early childhood pollicization. Methods 8 children who underwent 10 pollicizations (age at surgery ≤ 5 years) were evaluated 3 to 15 years after surgery. Anthropometrics, range of motion, and basic medical history were obtained. Participants completed an upper extremity questionnaire (PODCI) and functional tests including grip and pinch strength, Box and Blocks, 9-hole pegboard, and strength-dexterity (S-D) tests. Results Almost all pollicized hands had poor strength and performed poorly on the traditional functional tests. Six of 10 pollicized hands had normal dexterity scores but were less stable in maintaining a steady-state force. Predictors of poorer outcomes included older age at surgery, reduced metacarpophalangeal and interphalangeal range of motion, and radial absence. Discussion Early childhood pollicization resulted in poor strength and overall function, but normal dexterity was often achieved using altered control strategies. Conclusions Most children will likely obtain adequate dexterity despite weakness after pollicization, but older children and those with the most severe involvement may have poorer outcomes.

    Objective To determine the association between poor sleep quality, fatigue, and self-reported safety outcomes among Emergency Medical Services (EMS) workers. Methods We used convenience sampling of EMS agencies and a cross-sectional survey design. We administered the 19-item Pittsburgh Sleep Quality Index (PSQI), 11-item Chalder Fatigue Questionnaire (CFQ), and 44-item EMS Safety Inventory (EMS-SI) to measure sleep quality, fatigue, and safety outcomes, respectively. We used a consensus process to develop the EMS-SI, which was designed to capture three composite measurements of EMS worker injury, medical errors and adverse events (AE), and safety compromising behaviors. We used hierarchical logistic regression to test the association between poor sleep quality, fatigue, and three composite measures of EMS worker safety outcomes. Results We received 547 surveys from 30 EMS agencies (a 35.6% mean agency response rate). The mean PSQI score exceeded the benchmark for poor sleep (6.9, 95%CI 6.6, 7.2). Greater than half of respondents were classified as fatigued (55%, 95%CI 50.7, 59.3). Eighteen percent of respondents reported an injury (17.8%, 95%CI 13.5, 22.1), forty-one percent a medical error or AE (41.1%, 95%CI 36.8, 45.4), and 89% (95%CI 87, 92) safety compromising behaviors. After controlling for confounding, we identified 1.9 greater odds of injury (95%CI 1.1, 3.3), 2.2 greater odds of medical error or AE (95%CI 1.4, 3.3), and 3.6 greater odds of safety compromising behavior (95%CI 1.5, 8.3) among fatigued respondents versus non-fatigued respondents. Conclusions In this sample of EMS workers, poor sleep quality and fatigue is common. We provide preliminary evidence of an association between sleep quality, fatigue, and safety outcomes.

    2010-03-01

    The HIV epidemic in sub-Saharan Africa has caused many children to become orphaned and vulnerable. Recent studies show that orphaned and vulnerable children (OVC) lack the basic necessities for survival and development. These children are particularly at high risk of poor health and poverty. Although the poor health outcomes of these children are well documented, the complexities of the factors that mediate their health outcomes have not been systematically studied. The aim of this paper is to examine how the complex relationships between and within the proximate and socio-economic determinants mediate the poor health outcomes of children through their OVC status. The analyses considered graphical chain modelling of morbidity data from a sample of 3745 children aged below five years from the 2005 Rwandan Demographic and Health Survey. The results show that OVC status influences the risk of childhood morbidity both directly and indirectly and also as a conduit through which other significant proximate factors and socio-economic factors operate.

    Atrial fibrillation (AF) is a frequent cause of acute ischemic stroke that results in severe neurological disability and death despite treatment with intravenous thrombolysis (intravenous recombinant tissue plasminogen activator [rtPA]). We performed a retrospective review of a single-center registry of patients treated with intravenous rtPA for stroke. The purposes of this study were to compare intravenous rtPA treated patients with stroke with and without AF to examine independent predictors of poor hospital discharge outcome (in-hospital death or hospital discharge to a skilled nursing facility, long-term acute care facility, or hospice care). A univariate analysis was performed on 144 patients receiving intravenous rtPA for stroke secondary to AF and 190 patients without AF. Characteristics that were significantly different between the two groups were age, initial National Institutes of Health Stroke Scale score, length of hospital stay, gender, hypertension, hyperlipidemia, smoking status, presence of large cerebral infarct, and hospital discharge outcome. Bivariate logistic regression analysis indicated that patients with stroke secondary to AF with a poor hospital discharge outcome had a greater likelihood of older age, higher initial National Institutes of Health Stroke Scale scores, longer length of hospital stay, intubation, and presence of large cerebral infarct compared with those with good hospital discharge outcome (discharged to home or inpatient rehabilitation or signed oneself out against medical advice). A multivariate logistic regression analysis showed that older age, longer length of hospital stay, and presence of large cerebral infarct were independent predictors of poor hospital discharge outcome. These predictors can guide nursing interventions, aid the multidisciplinary treating team with treatment decisions, and suggest future directions for research. PMID:25503541

    The objective of this study was to evaluate the risk of adverse fetal outcome in systemic lupus erythematosus (SLE) women exposed to azathioprine during pregnancy. We reviewed the medical records of SLE pregnant women followed from January 2005 to April 2013. The patients were evaluated at least once in each trimester and postpartum. Relevant fetal outcomes were extracted, such as rate of liveborns, fetal loss (spontaneous abortion and stillbirth), term delivery, preterm birth, neonatal death, low birth weight, low birth weight at term, and congenital malformations. A detailed history of drug use during pregnancy was obtained. We studied 178 pregnancies (in 172 women), 87 of them were exposed to azathioprine (AZA-group) and the remaining 91 were not exposed (NO AZA-group). Exposure to other drugs was similar in both groups. The rate of live births, spontaneous abortions mean birth weight, weeks of gestation, rate of birth weight <2500 g, and low birth weight at term did not differ between groups. No infant had major congenital abnormalities. Multivariate analysis showed that preeclampsia, premature rupture of membranes (PROM), lupus flare, and anti-DNA positive were associated with an increased risk of poor fetal outcome. Our study suggests that the use of azathioprine is safe and lacks of teratogenity in patients with SLE and pregnancy. Exposure to azathioprine during pregnancy is not associated with poor fetal outcome. PMID:26050103

    Rates and risk factors for acquired drug resistance and association with outcomes among patients with multidrug-resistant tuberculosis (MDR TB) are not well defined. In an MDR TB cohort from the country of Georgia, drug susceptibility testing for second-line drugs (SLDs) was performed at baseline and every third month. Acquired resistance was defined as any SLD whose status changed from susceptible at baseline to resistant at follow-up. Among 141 patients, acquired resistance in Mycobacterium tuberculosis was observed in 19 (14%); prevalence was 9.1% for ofloxacin and 9.8% for capreomycin or kanamycin. Baseline cavitary disease and resistance to >6 drugs were associated with acquired resistance. Patients with M. tuberculosis that had acquired resistance were at significantly increased risk for poor treatment outcome compared with patients without these isolates (89% vs. 36%; p<0.01). Acquired resistance occurs commonly among patients with MDR TB and impedes successful treatment outcomes. PMID:25993036

    Background midregional proadrenomedullin (MR-proADM) is a prognostic biomarker in patients with community-acquired pneumonia (CAP). We sought to confirm whether MR-proADM added to Pneumonia Severity Index (PSI) improves the potential prognostic value of PSI alone, and tested to what extent this combination could be useful in predicting poor outcome of patients with CAP in an Emergency Department (ED). Methods Consecutive patients diagnosed with CAP were enrolled in this prospective, single-centre, observational study. We analyzed the ability of MR-proADM added to PSI to predict poor outcome using receiver operating characteristic (ROC) curves, logistic regression and risk reclassification and comparing it with the ability of PSI alone. The primary outcome was “poor outcome”, defined as the incidence of an adverse event (ICU admission, hospital readmission, or mortality at 30 days after CAP diagnosis). Results 226 patients were included; 33 patients (14.6%) reached primary outcome. To predict primary outcome the highest area under curve (AUC) was found for PSI (0.74 [0.64-0.85]), which was not significantly higher than for MR-proADM (AUC 0.72 [0.63-0.81, p > 0.05]). The combination of PSI and MR-proADM failed to improve the predictive potential of PSI alone (AUC 0.75 [0.65-0.85, p=0.56]). Ten patients were appropriately reclassified when the combined PSI and MR-proADM model was used as compared with the model of PSI alone. Net reclassification improvement (NRI) index was statistically significant (7.69%, p = 0.03) with an improvement percentage of 3.03% (p = 0.32) for adverse event, and 4.66% (P = 0.02) for no adverse event. Conclusion MR-proADM in combination with PSI may be helpful in individual risk stratification for short-term poor outcome of CAP patients, allowing a better reclassification of patients compared with PSI alone.

    Purpose The aim of this study was to identify the risk factors that are predictive of poor outcomes in penetrating globe trauma. Patients and methods This retrospective case series evaluated 103 eyes that had been surgically treated for an open-globe injury from 2007 to 2010 at the eye clinic of the University of Virginia. A total of 64 eyes with complete medical records and at least 6 months of follow-up were included in the study. Four risk factors (preoperative best-corrected visual acuity [pre-op BCVA], ocular trauma score [OTS], zone of injury [ZOI], and time lapse [TL] between injury and primary repair) and three outcomes (final BCVA, monthly rate of additional surgeries [MRAS], and enucleation) were identified for analysis. Results Pre-op BCVA was positively associated with MRAS, final BCVA, and enucleation. Calculated OTS was negatively associated with the outcome variables. No association was found between TL and ZOI with the outcome variables. Further, age and predictor variable-adjusted analyses showed pre-op BCVA to be independently positively associated with MRAS (P=0.008) and with final BCVA (P<0.001), while the calculated OTS was independently negatively associated with final BCVA (P<0.001), but not uniquely associated with MRAS (P=0.530). Conclusion Pre-op BCVA and OTS are best correlated with prognosis in open-globe injuries. However, no conventional features reliably predict the outcome of traumatized eyes. PMID:27536059

    AIM: To study the potential prognostic role of microRNA-382 (miR-382) in esophageal squamous cell carcinoma (ESCC). METHODS: Forty six patients were divided into 2 groups according to postoperative survival time: the poor outcome group (28 patients), who showed early metastasis but no recurrence, and died within 1 year after surgery, 12 patients of the group received postoperative chemotherapy treatment that was given after early metastasis happening; the good outcome group (18 patients), who had no clinical metastasis and recurrence, and survived 5 years or more after surgery, all patients did not receive any postoperative treatment. Total RNA was extracted from the patients’ formalin-fixed and paraffin-embedded esophageal cancer tissues. miR-382 level was evaluated using high-throughput real-time quantitative polymerase chain reaction analysis. The correlation between miR-382 level and clinicopathologic features was analyzed through COX regression model, and Kaplan-Meier analysis was used to analyze the relationship between miR-382 level and patient survival time. RESULTS: miR-382 was differentially expressed in the two groups. Overall the average miR-382 level in the ESCC patients with good outcome was 9.8 ± 3.8, while miR-382 level in the ESCC patients with poor outcome was 3.0 ± 0.8. The differences of miR-382 levels between two groups were significant (P < 0.05). Kaplan-Meier analysis results showed that miR-382 expression level generally had a significant reverse-correlation with ESCC patient survival time (P < 0.001), in which the patients with higher expressions of miR-382 had a longer survival time either among individuals with the same tumor stage or among the overall patients. CONCLUSION: miR-382 levels are reverse-correlated with ESCC poor outcomes, suggesting that miR-382 could be a potential predictive biomarker for both prognosis and treatment of ESCC. PMID:26078564

    Background ATP-binding cassette (ABC) transporters play various roles in cancer biology and drug resistance, but their association with outcomes in serous epithelial ovarian cancer (EOC) is unknown. Methods The relationship between clinical outcomes and ABC transporter gene expression in two independent cohorts of high-grade serous EOC tumors was assessed with real-time quantitative polymerase chain reaction, analysis of expression microarray data, and immunohistochemistry. Associations between clinical outcomes and ABCA transporter gene single nucleotide polymorphisms were tested in a genome-wide association study. Impact of short interfering RNA–mediated gene suppression was determined by colony forming and migration assays. Association with survival was assessed with Kaplan–Meier analysis and log-rank tests. All statistical tests were two-sided. Results Associations with outcome were observed with ABC transporters of the “A” subfamily, but not with multidrug transporters. High-level expression of ABCA1, ABCA6, ABCA8, and ABCA9 in primary tumors was statistically significantly associated with reduced survival in serous ovarian cancer patients. Low levels of ABCA5 and the C-allele of rs536009 were associated with shorter overall survival (hazard ratio for death = 1.50; 95% confidence interval [CI] =1.26 to 1.79; P = 6.5e−6). The combined expression pattern of ABCA1, ABCA5, and either ABCA8 or ABCA9 was associated with particularly poor outcome (mean overall survival in group with adverse ABCA1, ABCA5 and ABCA9 gene expression = 33.2 months, 95% CI = 26.4 to 40.1; vs 55.3 months in the group with favorable ABCA gene expression, 95% CI = 49.8 to 60.8; P = .001), independently of tumor stage or surgical debulking status. Suppression of cholesterol transporter ABCA1 inhibited ovarian cancer cell growth and migration in vitro, and statin treatment reduced ovarian cancer cell migration. Conclusions Expression of ABCA transporters was associated with poor

    Negative symptoms, particularly amotivation/apathy, are intimately tied to functional outcomes.

    Objectives Mutations in the gyrase genes cause fluoroquinolone resistance in Mycobacterium tuberculosis. However, the predictive value of these markers for clinical outcomes in patients with MDR-TB is unknown to date. The objective of this study was to determine molecular markers and breakpoints predicting second-line treatment outcomes in M. tuberculosis patients treated with fourth-generation fluoroquinolones. Methods We analysed treatment outcome data in relation to the gyrA and gyrB sequences and MICs of ofloxacin, gatifloxacin and moxifloxacin for pretreatment M. tuberculosis isolates from 181 MDR-TB patients in Bangladesh whose isolates were susceptible to injectable drugs. Results The gyrA 90Val, 94Gly and 94Ala mutations were most frequent, with the highest resistance levels for 94Gly mutants. Increased pretreatment resistance levels (>2 mg/L), related to specific mutations, were associated with lower cure percentages, with no cure in patients whose isolates were resistant to gatifloxacin at 4 mg/L. Any gyrA 94 mutation, except 94Ala, predicted a significantly lower proportion of cure compared with all other gyrA mutations taken together (all non-94 mutants + 94Ala) [OR = 4.3 (95% CI 1.4–13.0)]. The difference in treatment outcome was not explained by resistance to the other drugs. Conclusions Our study suggests that gyrA mutations at position 94, other than Ala, predict high-level resistance to gatifloxacin and moxifloxacin, as well as poor treatment outcome, in MDR-TB patients in whom an injectable agent is still effective.

We aimed to assess factors associated with such control among HIV/AIDS patients in Malaysia. Four hundred and six HIV/AIDS patients, using Antiretroviral Therapy (ART) for at least the past three months, treated as outpatients at medication therapy adherence clinics (MTAC) were recruited. CD4 cell counts, viral load readings along with co-variants such as socio-demographic factors, adverse drug reactions, comorbidities, and medication record were obtained. Statistical Package for Social Sciences (SPSS(®)) version 18 and STATA IC(®) version 12 were used for data analysis. CD4 counts were found highest among those within the age category 41-50 years (390.43 ± 272.28), female (402.64 ± 276.14), other ethnicities (400.20 ± 278.04), and participants with no formal education (414.87 ± 290.90). Patients experiencing adverse effects had a 2.28 (95%CI:1.25-4.18) fold greater risk of poor CD4 control, while patients with comorbidities had 2.46 (95%CI:1.02-5.91) fold greater risk of mild viral suppression. Adverse drug reactions, co-morbidities were found to be significantly associated with poor immunological and virological outcomes in HIV/AIDS patients. However, a comprehensive evaluation is needed to better understand other confounders. PMID:26399724

    Background: Periosteal osteosarcoma is an uncommon variant of osteosarcoma which constitutes less than 2% of all osteosarcomas. Whereas adequate surgical excision remains the cornerstone of treatment, the role of chemotherapy in this tumor is still unclear. Existing literature contains very few single center studies on the outcomes for periosteal osteosarcomas and any additional information will help in better understanding of these uncommon lesions. This study aims to evaluate the oncologic and functional outcomes of treatment of periosteal osteosarcoma treated at our institute. Materials and Methods: A retrospective analysis of 18 cases of periosteal osteosarcoma treated between January 2001 and December 2010 was carried out. There were 12 males and 6 females. The mean age at presentation was 16.3 years (range 5-26 years). Tibia and femur were the most common sites (n = 8). 16 of 18 patients received chemotherapy, 16 had limb sparing resection, one had an amputation and one had rotationplasty. Of the 16 patients with limb salvage, conventional wide excision was done in 11 cases. In 5 cases tumor was excised with hemicortical excision. Of the 11 cases treated with wide excisions, 4 patients underwent an osteoarticular resection and in 7 patients a joint preserving segmental intercalary resection was done. Results: All patients were available for followup. Surgical margins were free in all patients. A good response to chemotherapy was seen in 4/11 cases and poor in 6/11 cases. In one case the histological response was not discernible due to predominant chondromyxoid nature of the tumor. The median followup was 61 months (range: 18-130 months). There were two local recurrences (11%) at 9 and 18 months postsurgery. Pulmonary metastasis subsequently occurred in 4 cases (22%). Fourteen patients are currently alive and continuously disease free. Disease free survival at 5 years was 77.8% and overall survival (OVS) was 83.3%. Patients without marrow involvement had a

    The less affected hemisphere is important in motor recovery in mature brains. However, in terms of motor outcome in immature brains, no study has been reported on the less affected corticospinal tract in hemiplegic pediatric patients. Therefore, we examined the relationship between the condition of the less affected corticospinal tract and motor function in hemiplegic pediatric patients. Forty patients with hemiplegia due to perinatal or prenatal injury (13.7 ± 3.0 months) and 40 age-matched typically developing controls were recruited. These patients were divided into two age-matched groups, the high functioning group (20 patients) and the low functioning group (20 patients) using functional level of hemiplegia scale. Diffusion tensor tractography images showed that compared with the control group, the patient group of the less affected corticospinal tract showed significantly increased fiber number and significantly decreased fractional anisotropy value. Significantly increased fiber number and significantly decreased fractional anisotropy value in the low functioning group were observed than in the high functioning group. These findings suggest that activation of the less affected hemisphere presenting as increased fiber number and decreased fractional anisotropy value is related to poor motor function in pediatric hemiplegic patients.

    2015-01-01

    Acute myeloid leukemia in adults is a highly heterogeneous disease. Gene expression profiling performed using unsupervised algorithms can be used to distinguish specific groups of patients within a large patient cohort. The identified gene expression signatures can offer insights into underlying physiological mechanisms of disease pathogenesis. Here, the analysis of several related gene expression clusters associated with poor outcome, worst overall survival and highest rates of resistant disease and obtained from the patients at the time of diagnosis or from previously untreated individuals is presented. Surprisingly, these gene clusters appear to be enriched for genes corresponding to proteins involved in transport across membranes (transporters, carriers and channels). Several ideas describing the possible relationship of membrane transport activity and leukemic cell biology, including the “Warburg effect,” the specific role of chloride ion transport, direct “import” of metabolic energy through uptake of creatine phosphate, and modification of the bone marrow niche microenvironment are discussed.

    Notch signaling abnormalities are reported to be involved in the acceleration of malignancy in solid tumors and stem cell formation or regeneration in various organs. We analyzed specific genes for DNA copy number variations in liver cancer cells and investigated whether these factors relate to clinical outcome. Chromosome 20p, which includes the ligand for Notch pathways, Jagged1, was found to be amplified in several types of hepatoma cells, and its mRNA was up-regulated according to α-fetoprotein gene expression levels. Notch inhibition using Jagged1 shRNA and γ-secretase inhibitors produced significant suppression of cell growth in α-fetoprotein-producing cells with suppression of downstream genes. Using in vivo hepatoma models, the administration of γ-secretase inhibitors resulted in reduced tumor sizes and effective Notch inhibition with widespread apoptosis and necrosis of viable tumor cells. The γ-secretase inhibitors suppressed cell growth of the epithelial cell adhesion molecule-positive fraction in hepatoma cells, indicating that Notch inhibitors could suppress the stem cell features of liver cancer cells. Even in clinical liver cancer samples, the expression of α-fetoprotein and Jagged1 showed significant correlation, and amplification of the copy number of Jagged1 was associated with Jagged1 mRNA expression and poor survival after liver cancer surgical resection. In conclusion, amplification of Jagged1 contributed to mRNA expression that activates the Jagged1-Notch signaling pathway in liver cancer and led to poor outcome. PMID:27315779

    Elderly burn care represents a vast challenge. The elderly are one of the most susceptible populations to burn injuries, but also one of the fastest growing demographics, indicating a substantial increase in patient numbers in the near future. Despite the need and importance of elderly burn care, survival of elderly burn patients is poor. Additionally, little is known about the responses of elderly patients after burn. One central question that has not been answered is what age defines an elderly patient. The current study was conducted to determine whether there is a cut-off age for elderly burn patients that is correlated with an increased risk for mortality and to determine the burn size in modern burn care that is associated with increased mortality. To answer these questions, we applied appropriate statistical analyses to the Ross Tilley Burn Centre and the Inflammatory and Host Response to Injury databases. We could not find a clear cut-off age that differentiates or predicts between survival and death. Risk of death increased linearly with increasing age. Additionally, we found that the LD50 decreases from 45% total body surface area (TBSA) to 25% TBSA from the age of 55 years to the age of 70 years, indicating that even small burns lead to poor outcome in the elderly. We therefore concluded that age is not an ideal to predictor of burn outcome, but we strongly suggest that burn care providers be aware that if an elderly patient sustains even a 25% TBSA burn, the risk of mortality is 50% despite the implementation of modern protocolized burn care.

    Background Hypocalcemia is a marker of poor prognosis in acute pancreatitis (AP) but the prognostic significance of hypocalcemic tetany in patients with AP has not been studied. We aimed to determine the prognostic significance of hypocalcemic tetany in patients with AP. Methods Consecutive patients of AP who presented within 7 days of symptoms were included. Serum calcium levels were measured on admission and the patients were divided into two groups based on the presence (group 1) or absence of hypocalcemia (group 2). Chvostek and Trousseau signs were sought in all patients with hypocalcemia and the outcome measures were compared between patients with normocalcemia, asymptomatic and symptomatic hypocalcemia (tetany). The outcome parameters assessed were persistent organ failure (POF), need for intervention, and mortality. Results Of 105 patients (53 male; mean age 37.34±12.62 years), 37 (35.2%) had hypocalcemia (group 1) and 68 (64.8%) had normal corrected serum calcium levels (group 2). Patients with hypocalcemia had significantly higher frequency of POF, mortality and need for intervention (P<0.05). Twelve of 37 (32.4%) patients with hypocalcemia had tetany. Patients with tetany had significantly lower serum corrected calcium and ionized calcium levels compared with patients with asymptomatic hypocalcemia (P<0.05). Patients with tetany had significantly higher mortality rates compared with patients with asymptomatic hypocalcemia (100% vs. 8%; P=0.00001) as well as POF (100% vs. 32%; P=0.000006). Conclusion Presence of hypocalcemic tetany in AP patients bears a poor prognosis and is associated with increased mortality. PMID:27065735

    Background Invasive pneumococcal disease (IPD) causes considerable morbidity and mortality. We aimed to identify host factors and biomarkers associated with poor outcomes in adult patients with IPD in Japan, which has a rapidly-aging population. Methods In a large-scale surveillance study of 506 Japanese adults with IPD, we investigated the role of host factors, disease severity, biomarkers based on clinical laboratory data, treatment regimens, and bacterial factors on 28-day mortality. Results Overall mortality was 24.1%, and the mortality rate increased from 10.0% in patients aged ˂50 years to 33.1% in patients aged ≥80 years. Disease severity also increased 28-day mortality, from 12.5% among patients with bacteraemia without sepsis to 35.0% in patients with severe sepsis and 56.9% with septic shock. The death rate within 48 hours after admission was high at 54.9%. Risk factors for mortality identified by multivariate analysis were as follows: white blood cell (WBC) count <4000 cells/μL (odds ratio [OR], 6.9; 95% confidence interval [CI], 3.7–12.8, p < .001); age ≥80 years (OR, 6.5; 95% CI, 2.0–21.6, p = .002); serum creatinine ≥2.0 mg/dL (OR, 4.5; 95% CI, 2.5–8.1, p < .001); underlying liver disease (OR, 3.5; 95% CI, 1.6–7.8, p = .002); mechanical ventilation (OR, 3.0; 95% CI, 1.7–5.6, p < .001); and lactate dehydrogenase ≥300 IU/L (OR, 2.4; 95% CI, 1.4–4.0, p = .001). Pneumococcal serotype and drug resistance were not associated with poor outcomes. Conclusions Host factors, disease severity, and biomarkers, especially WBC counts and serum creatinine, were more important determinants of mortality than bacterial factors. PMID:26815915

    Background Older adults (≥ 65 yr) are the fastest growing population and are presenting in increasing numbers for acute surgical care. Emergency surgery is frequently life threatening for older patients. Our objective was to identify predictors of mortality and poor outcome among elderly patients undergoing emergency general surgery. Methods We conducted a retrospective cohort study of patients aged 65–80 years undergoing emergency general surgery between 2009 and 2010 at a tertiary care centre. Demographics, comorbidities, in-hospital complications, mortality and disposition characteristics of patients were collected. Logistic regression analysis was used to identify covariate-adjusted predictors of in-hospital mortality and discharge of patients home. Results Our analysis included 257 patients with a mean age of 72 years; 52% were men. In-hospital mortality was 12%. Mortality was associated with patients who had higher American Society of Anesthesiologists (ASA) class (odds ratio [OR] 3.85, 95% confidence interval [CI] 1.43–10.33, p = 0.008) and in-hospital complications (OR 1.93, 95% CI 1.32–2.83, p = 0.001). Nearly two-thirds of patients discharged home were younger (OR 0.92, 95% CI 0.85–0.99, p = 0.036), had lower ASA class (OR 0.45, 95% CI 0.27–0.74, p = 0.002) and fewer in-hospital complications (OR 0.69, 95% CI 0.53–0.90, p = 0.007). Conclusion American Society of Anesthesiologists class and in-hospital complications are perioperative predictors of mortality and disposition in the older surgical population. Understanding the predictors of poor outcome and the importance of preventing in-hospital complications in older patients will have important clinical utility in terms of preoperative counselling, improving health care and discharging patients home.

    The clinical and functional significance of RNA interference (RNAi) machinery, Dicer and Drosha, in ovarian cancer is not known and was examined. Dicer and Drosha expression was measured in ovarian cancer cell lines (n=8) and invasive epithelial ovarian cancer specimens (n=111) and correlated with clinical outcome. Validation was performed with previously published cohorts of ovarian, breast, and lung cancer patients. Anti-Galectin-3 siRNA and shRNA transfections were used for in vitro functional studies. Dicer and Drosha mRNA and protein levels were decreased in 37% to 63% of ovarian cancer cell lines and in 60% and 51% of human ovarian cancer specimens, respectively. Low Dicer was significantly associated with advanced tumor stage (p=0.007), and low Drosha with suboptimal surgical cytoreduction (p=0.02). Tumors with both high Dicer and Drosha were associated with increased median patient survival (>11 years vs. 2.66 years for other groups; p<0.001). In multivariate analysis, high Dicer (HR=0.48; p=0.02), high-grade histology (HR=2.46; p=0.03), and poor chemoresponse (HR=3.95; p<0.001) were identified as independent predictors of disease-specific survival. Findings of poor clinical outcome with low Dicer expression were validated in separate cohorts of cancer patients. Galectin-3 silencing with siRNA transfection was superior to shRNA in cell lines with low Dicer (78-95% vs. 4-8% compared to non-targeting sequences), and similar in cell lines with high Dicer. Our findings demonstrate the clinical and functional impact of RNAi machinery alterations in ovarian carcinoma and support the use of siRNA constructs that do not require endogenous Dicer and Drosha for therapeutic applications.

    To assess the associations between Intimate Partner Violence (IPV) victimization and health outcomes of South Asian women in Greater Boston. To explore the nature of the health experiences of victimized women in this population. Cross-sectional surveys with a community-based sample of women in relationships with males (n = 208) assessed demographics, IPV history, and health. In-depth interviews were conducted with a separate sample of women with a history of IPV (n = 23). Quantitative data were assessed by logistic regression, qualitative data by a grounded theory approach. Twenty-one percent of the quantitative sample reported IPV in the current relationship. Abused women were significantly more likely than those with no history of IPV in their current relationship to report poor physical health (95% CI = 1.3-12.0), depression (95% CI = 1.8-9.3), anxiety (95% CI = 1.3-6.4), and suicidal ideation (95% CI = 1.9-25.1). Qualitative subjects described how victimization resulted in injury and chronic health concerns and how IPV-induced depression and anxiety affected their sleep, appetite, energy, and wellbeing. Experiences of IPV are related to increased poor health among South Asian women. This elevated risk demands intervention. Healthcare providers should be trained to screen and refer South Asian patients for partner violence. PMID:16791535

    Background Violence during childhood may affect short and long-term educational factors. There is scant literature on younger children from resource poor settings. Methods This study assessed child violence experiences (harsh punishment and exposure to domestic or community violence) and school enrolment, progress and attendance in children attending community-based organisations in South Africa and Malawi (n=989) at baseline and at 15 months' follow-up, examining differential experience of HIV positive, HIV affected and HIV unaffected children. Results Violence exposure was high: 45.4% experienced some form of psychological violence, 47.8% physical violence, 46.7% domestic violence and 41.8% community violence. Primary school enrolment was 96%. Violence was not associated with school enrolment at baseline but, controlling for baseline, children exposed to psychological violence for discipline were more than ten times less likely to be enrolled at follow-up (OR 0.09; 95% CI 0.01 to 0.57). Harsh discipline was associated with poor school progress. For children HIV positive a detrimental effect of harsh physical discipline was found on school performance (OR 0.10; 95% CI 0.02 to 0.61). Conclusion Violence experiences were associated with a number of educational outcomes, which may have long-term consequences. Community-based organisations may be well placed to address such violence, with a particular emphasis on the challenges faced by children who are HIV positive. PMID:26678567

    OBJECTIVE Spinal meningiomas are benign tumors with a wide spectrum of clinical and radiological features at presentation. The authors analyzed multiple clinicoradiological factors to predict recurrence and functional outcome in a cohort with a mean follow-up of more than 4 years. The authors also discuss the results of clinical studies regarding spinal meningiomas in the last 15 years. METHODS The authors retrospectively reviewed the clinical and radiological details of patients who underwent surgery for spinal tumors between 2001 and 2015 that were histopathologically confirmed as meningiomas. Demographic parameters, such as age, sex, race, and association with neurofibromatosis Type 2, were considered. Radiological parameters, such as tumor size, signal changes of spinal cord, spinal level, number of levels, location of tumor attachment, shape of tumor, and presence of dural tail/calcification, were noted. These factors were analyzed to predict recurrence and functional outcome. Furthermore, a pooled analysis was performed from 13 reports of spinal meningiomas in the last 15 years. RESULTS A total of 38 patients were included in this study. Male sex and tumors with radiological evidence of a dural tail were associated with an increased risk of recurrence at a mean follow-up of 51.2 months. Ventral or ventrolateral location, large tumors, T2 cord signal changes, and poor preoperative functional status were associated with poor functional outcome at 1-year follow-up. CONCLUSIONS Spine surgeons must be aware of the natural history and risk factors of spinal meningiomas to establish a prognosis for their patients. PMID:27476848

    We examined the relationships between parent-adolescent discrepancies in perceived parenting characteristics (indexed by parental responsiveness, parental demandingness, and parental control) and adolescent developmental outcomes (indexed by achievement motivation and psychological competence) in poor families in Hong Kong. A sample of 275 intact families having at least one child aged 11-16 experiencing economic disadvantage were invited to participate in the study. Fathers and mothers completed the Parenting Style Scale and Chinese Parental Control Scale, and adolescents completed the Social-Oriented Achievement Motivation Scale and Chinese Positive Youth Development Scale in addition to paternal and maternal Parenting Style Scale and Chinese Parental Control Scale. Results indicated that parents and adolescents had different perceptions of parental responsiveness, parental demandingness, and paternal control, with adolescents generally perceived lower levels of parenting behaviors than did their parents. While father-adolescent discrepancy in perceived paternal responsiveness and mother-adolescent discrepancy in perceived maternal control negatively predicted adolescent achievement motivation, mother-adolescent discrepancy in perceptions of maternal responsiveness negatively predicted psychological competence in adolescents experiencing economic disadvantage. The present findings provided support that parent-child discrepancies in perceived parenting characteristics have negative impacts on the developmental outcomes of adolescents experiencing economic disadvantage. The present study addresses parent-child discrepancies in perceived parental behaviors as "legitimate" constructs, and explores their links with adolescent psychosocial development, which sheds light for researchers and clinical practitioners in helping the Chinese families experiencing economic disadvantage.

    Cognitive dysfunction is a core feature of schizophrenia. Deficits are moderate to severe across several domains, including attention, working memory, verbal learning and memory, and executive functions. These deficits pre-date the onset of frank psychosis and are stable throughout the course of the illness in most patients. Over the past decade, the focus on these deficits has increased dramatically with the recognition that they are consistently the best predictor of functional outcomes across outcome domains and patient samples. Recent treatment studies, both pharmacological and behavioral, suggest that cognitive deficits are malleable. Other research calls into question the meaningfulness of cognitive change in schizophrenia. In this article, we review cognitive deficits in schizophrenia and focus on their treatment and relationship to functional outcome. PMID:19412501

    Background Sleep disturbance is bi-directionally related to mood de-stabilization in bipolar disorder (BD), and sleep quality differs in men and women. We aimed to determine whether perception of poor sleep quality would have a different effect on mood outcome in men versus women. Methods We assessed association between sleep quality (Pittsburgh Sleep Quality Index (PSQI)) at study intake and mood outcome over 2 years in subjects from the Prechter Longitudinal Study of Bipolar Disorder (N=216; 29.6% males). The main outcome measure was the severity, variability, and frequency of mood episodes measured by self-report over 2 years of follow-up. Multivariable linear regression models stratified by sex examined the relationship between PSQI with mood outcomes, while age, stressful life events, mood state and neuroticism at baseline were controlled. Results In women, poor sleep quality at baseline predicted increased severity (B=0.28, p<0.001) and frequency of episodes (B=0.32, p<0.001) of depression, and poor sleep quality was a stronger predictor than baseline depression; poor sleep quality predicted increased severity (B=0.19, p<0.05) and variability (B=0.20, p<0.05) of mania, and frequency of mixed episodes (B=0.27, p<0.01). In men, baseline depression and neuroticism were stronger predictors of mood outcome compared to poor sleep quality. Limitations We measured perception of sleep quality, but not objective changes in sleep. Conclusions In a longitudinal study of BD, women reported poorer perceived sleep quality than men, and poor sleep quality predicted worse mood outcome in BD. Clinicians should be sensitive to addressing sleep complaints in women with BD early in treatment to improve outcome in BD. PMID:25885066

    Background and purpose - In preparing patients for total hip replacement surgery, providing thorough information helps to reduce anxiety, manage postoperative pain, prevent complications, and better engage patients in their rehabilitation. However, patient characteristics may have an influence on the ability to comprehend and assimilate the information given. We investigated differences in patients born in Sweden and those born outside Sweden regarding how they perceived the information given before THR, and if this was associated with different patient-reported outcomes one year after surgery. Patients and methods - From Sahlgrenska University Hospital, we recruited 150 patients born in Sweden and 50 patients born outside Sweden who were to undergo THR. We retrieved routinely collected data from the Swedish Hip Arthroplasty Register including basic demographic variables and patient-reported outcome measures, both preoperatively and at 1-year follow-up. In a separate survey carried out 1-2 weeks after surgery, patients were asked about the information provided in connection with the operation. Results - Patients born outside Sweden more frequently reported that they were poorly informed about possibilities to treat pain and about the operation itself. 1 year after the operation, patients born outside Sweden who, 1-2 weeks after the operation, had reported that they were poorly informed also reported having worse outcomes. Poorer results were found for the questions self-care and anxiety/depression in the EQ-5D questionnaire, pain on a visual analog scale (VAS), EQVAS, and EQ-5D index compared to those patients born in Sweden who had received at least some information of acceptable quality. Interpretation - One quarter of the patients were not satisfied with the information provided before and after THR. These patients more commonly reported perioperative anxiety and they were more often born outside Sweden. Poorly informed patients who had come from countries

    Background: Protein phosphatase 2A (PP2A) is a tumour suppressor frequently inactivated in human cancer and its tyrosine-307 phosphorylation has been reported as a molecular inhibitory mechanism. Methods: Expression of phosphorylated PP2A (p-PP2A) was evaluated in 250 metastatic colorectal cancer (CRC) patients. Chi-square, Kaplan–Meier and Cox analyses were used to determine correlations with clinical and molecular parameters and impact on clinical outcomes. Results: High p-PP2A levels were found in 17.2% cases and were associated with ECOG performance status (P=0.001) and presence of synchronous metastasis at diagnosis (P=0.035). This subgroup showed substantially worse overall survival (OS) (median OS, 6.0 vs 26.2 months, P<0.001) and progression-free survival (PFS) (median PFS, 3.8 vs 13.3 months, P<0.001). The prognostic impact of p-PP2A was particularly evident in patients aged <70 years (P<0.001). Multivariate analysis revealed that p-PP2A retained its prognostic impact for OS (hazard ratio 2.7; 95% confidence interval, 1.8–4.1; P<0.001) and PFS (hazard ratio 3.0; 95% confidence interval, 1.8–5.0; P<0.001). Conclusions: Phosphorylated PP2A is an alteration that determines poor outcome in metastatic CRC and represents a novel potential therapeutic target in this disease, thus enabling to define a subgroup of patients who could benefit from future treatments based on PP2A activators.

    Background and Purpose Few studies have analyzed the clinical course and functional outcome in Leigh syndrome (LS). The aim of this study was to determine the clinical, radiological, biochemical, and genetic features of patients with LS, and identify prognostic indicators of the disease progression and neurological outcome. Methods Thirty-nine patients who had been diagnosed with LS at the Seoul National University Children's Hospital were included. Their medical records, neuroimaging findings, and histological/biochemical findings of skeletal muscle specimens were reviewed. Targeted sequencing of mitochondrial DNA was performed based on mitochondrial respiratory chain (MRC) enzyme defects. Results Isolated complex I deficiency was the most frequently observed MRC defect (in 42% of 38 investigated patients). Mitochondrial DNA mutations were identified in 11 patients, of which 81.8% were MT-ND genes. The clinical outcome varied widely, from independent daily activity to severe disability. Poor functional outcomes and neurological deterioration were significantly associated with early onset (before an age of 1 year) and the presence of other lesions additional to basal ganglia involvement in the initial neuroimaging. Conclusions The neurological severity and outcome of LS may vary widely and be better than those predicted based on previous studies. We suggest that age at onset and initial neuroimaging findings are prognostic indicators in LS. PMID:27074294

    Tristetraprolin (also known as TTP, TIS11, ZFP36, and Nup475) is a well-characterized tumor suppressor that is down-regulated in several tumor types. In the current study, we found that TTP expression was markedly reduced in pancreatic cancer samples as compared to matched normal tissues. Low TTP level was associated with age (P=0.037), tumor size (P=0.008), tumor differentiation (P=0.004), postoperative T stage (pT stage, P<0.001), postoperative N stage (pN stage, P=0.008) and TNM stage (P<0.001). Moreover, low TTP expression predicted reduced survival rates and poor patient outcome. We also found that TTP impairs pancreatic cancer cell proliferation both in vivo and in vitro. Fluorescence Activated Cell Sorting (FACS) assay showed that TTP over-expression both increases apoptosis and decreases proliferation in pancreatic cancer cells. RNA-sequencing analysis showed that TTP over-expression downregulates several tumor-related factors, including Pim-1 and IL-6. Our findings indicate that TTP could serve as a potential prognostic indicator in pancreatic cancer. PMID:26894969

    Metal-on-metal (MoM) bearings for total hip arthroplasty (THA) have come under scrutiny with reports of high failure rates. Clinical outcome studies with several commercially available MoM THA bearings remain unreported. We evaluated 78 consecutive MoM THAs from a single manufacturer in 68 patients. Sixty-six received cobalt-chrome (CoCr) monoblock and 12 received modular titanium acetabular cups with internal CoCr liners. Femoral components were titanium with modular necks. At average 2.1 years postoperatively, 12 THAs (15.4%) demonstrated aseptic failure (10 revisions, 2 revision recommended). All revised hips demonstrated capsular necrosis with positive histology reaction for aseptic lymphocytic vasculitis-associated lesions/adverse local tissue reactions. Prosthetic instability following revision surgery was relatively common. Female gender was a strong risk factor for failure, though smaller cups were not. Both monoblock and modular components fared poorly. Corrosion was frequently observed around the proximal and distal end of the modular femoral necks. PMID:23538122

    Background Hemorrhagic shock (HS) following trauma is a leading cause of death among persons under the age of 40. During HS the body undergoes systemic warm ischemia followed by reperfusion during medical intervention. Ischemia/reperfusion (I/R) results in a disruption of cellular metabolic processes that ultimately lead to tissue and organ dysfunction or failure. Resistance to I/R injury is a characteristic of hibernating mammals. The present study sought to identify circulating metabolites in the rat as biomarkers for metabolic alterations associated with poor outcome after HS. Arctic ground squirrels (AGS), a hibernating species that resists I/R injury independent of decreased body temperature (warm I/R), was used as a negative control. Methodology/principal findings Male Sprague-Dawley rats and AGS were subject to HS by withdrawing blood to a mean arterial pressure (MAP) of 35 mmHg and maintaining the low MAP for 20 min before reperfusing with Ringers. The animals’ temperature was maintained at 37±0.5°C for the duration of the experiment. Plasma samples were taken immediately before hemorrhage and three hours after reperfusion. Hydrophilic and lipid metabolites from plasma were then analyzed via 1H–NMR from unprocessed plasma and lipid extracts, respectively. Rats, susceptible to I/R injury, had a qualitative shift in their hydrophilic metabolic fingerprint including differential activation of glucose and anaerobic metabolism and had alterations in several metabolites during I/R indicative of metabolic adjustments and organ damage. In contrast, I/R injury resistant AGS, regardless of season or body temperature, maintained a stable metabolic homeostasis revealed by a qualitative 1H–NMR metabolic profile with few changes in quantified metabolites during HS-induced global I/R. Conclusions/significance An increase in circulating metabolites indicative of anaerobic metabolism and activation of glycolytic pathways is associated with poor prognosis after HS in

    Overexpression of human leukocyte antigen-G (HLA-G), a non-classical major histocompatibility complex class-I molecule associated with immunosuppression, has been reported in various human malignancies. In the present study, we examined the role of HLA-G in gliomas. Clinical characteristics, mRNA expression microarrays and follow-up data pertaining to 293 patients with histologically confirmed gliomas were analyzed. The expression levels of HLA-G were compared between different grades of gliomas and correlated with progression-free survival (PFS) and overall survival (OS) to evaluate its prognostic value. We found that HLA-G was overexpressed in gliomas as compared to that in normal brain tissue samples (-1.288±0.265). The highest expression levels were in glioblastomas (GBMs), anaplastic gliomas (AGs) and low-grade gliomas (LGGs), in that order (0.328±0.778, 0.176±0.881, -0.388±0.686, respectively). Significant inter-group differences were observed between low-grade and high-grade glioma tissues (p<0.001 and p<0.001, t-test, AGs and GBMs, respectively). More astrocytoma patients exhibited increased HLA-G expression as compared to other LGG patients (p=0.004, Chi-square test). Significant differences were observed with respect to PFS and OS (p=0.009 and 0.032, log-rank test, for PFS and OS, respectively) between the high- and low-expression subgroups in patients with LGGs. On Cox regression analysis, overexpression of HLA-G appeared to be an independent predictor of clinical outcomes (p=0.007 and 0.026, for PFS and OS, respectively). Our results suggest that HLA-G expression may serve as a potential biomarker for predicting aggressive tumor grades of gliomas and for histological subtype of LGGs. Elevated HLA-G expression could serve as an independent predictor of poor clinical outcomes in patients with low-grade gliomas. PMID:27138095

    Background Although increasing evidence suggests that hyperglycemia following acute stroke adversely affects clinical outcome, whether the association between glycaemia and functional outcome varies between stroke patients with\\without pre-diagnosed diabetes remains controversial. We aimed to investigate the relationship between the fasting blood glucose (FBG) and the 6-month functional outcome in a subgroup of SMART cohort and further to assess whether this association varied based on the status of pre-diagnosed diabetes. Methods Data of 2862 patients with acute ischemic stroke (629 with pre-diagnosed diabetics) enrolled from SMART cohort were analyzed. Functional outcome at 6-month post-stroke was measured by modified Rankin Scale (mRS) and categorized as favorable (mRS:0–2) or poor (mRS:3–5). Binary logistic regression model, adjusting for age, gender, educational level, history of hypertension and stroke, baseline NIHSS and treatment group, was used in the whole cohort to evaluate the association between admission FBG and functional outcome. Stratified logistic regression analyses were further performed based on the presence/absence of pre-diabetes history. Results In the whole cohort, multivariable logistical regression showed that poor functional outcome was associated with elevated FBG (OR1.21 (95%CI 1.07–1.37), p = 0.002), older age (OR1.64 (95% CI1.38–1.94), p<0.001), higher NIHSS (OR2.90 (95%CI 2.52–3.33), p<0.001) and hypertension (OR1.42 (95%CI 1.13–1.98), p = 0.04). Stratified logistical regression analysis showed that the association between FBG and functional outcome remained significant only in patients without pre-diagnosed diabetes (OR1.26 (95%CI 1.03–1.55), p = 0.023), but not in those with premorbid diagnosis of diabetes (p = 0.885). Conclusion The present results demonstrate a significant association between elevated FBG after stroke and poor functional outcome in patients without pre-diagnosed diabetes, but not in diabetics

    Dysregulation of microRNA let-7a-3 has been identified in several solid tumors and is associated with prognosis of patients. However, the pattern of let-7a-3 expression and the impact on prognosis has not yet been studied in acute myeloid leukemia (AML). The purpose of this study is to investigate the expression status of let-7a-3 and its clinical significance in AML patients using real-time quantitative PCR. Overexpression of let-7a-3 was identified in 25 of 102 (25%) de novo AML. There was no significant difference in age, blood parameters, FAB/WHO subtypes, karyotype risks and nine gene mutations (FLT3-ITD, NPM1, C-KIT, IDH1/IDH2, DNMT3A, C/EBPA and N/K-RAS) between patients with and without let-7a-3 overexpression (P>0.05). The patients with let-7a-3 overexpression had similar rates of complete remission (CR) as those without let-7a-3 overexpression (50% vs. 56%, P=0.693). Although the overall survival (OS) of AML patients with let-7a-3 overexpression (median 12 months,) was shorter than those without overexpression (median 25 months), the difference was not statistically significant (P=0.228). However, among those 51 obtained CR, patients with let-7a-3 overexpression had significantly shorter OS than those without let-7a-3 overexpression (P=0.029). The difference in relapse-free survival (RFS) was also significant between two groups (P=0.005). These findings suggest that let-7a-3 overexpression is a common event and is associated with poor clinical outcome in AML. PMID:24138945

    Low DICER1 expression was associated with poor outcome in several cancers. Recently, hot-spot DICER1 mutations were found in ovarian tumors, and TARBP2 truncating mutations in tumor cell lines with microsatellite instability. In this study, we assessed DICER1 e TRBP protein expression in 154 adult adrenocortical tumors (75 adenomas and 79 carcinomas). Expression of DICER1 and TARBP2 gene was assessed in a subgroup of 61 tumors. Additionally, we investigated mutations in metal biding sites located at the RNase IIIb domain of DICER1 and in the exon 5 of TARBP2 in 61 tumors. A strong DICER1 expression was demonstrated in 32% of adenomas and in 51% of carcinomas (p = 0.028). Similarly, DICER1 gene overexpression was more frequent in carcinomas (60%) than in adenomas (23%, p = 0.006). But, among adrenocortical carcinomas, a weak DICER1 expression was significantly more frequent in metastatic than in non-metastatic adrenocortical carcinomas (66% vs. 31%; p = 0.002). Additionally, a weak DICER1 expression was significantly correlated with a reduced overall (p = 0.004) and disease-free (p = 0.005) survival. In the multivariate analysis, a weak DICER1 expression (p = 0.048) remained as independent predictor of recurrence. Regarding TARBP2 gene, its protein and gene expression did not correlate with histopathological and clinical parameters. No variant was identified in hot spot areas of DICER1 and TARBP2. In conclusion, a weak DICER1 protein expression was associated with reduced disease-free and overall survival and was a predictor of recurrence in adrenocortical carcinomas. PMID:26087193

    Borderline intellectual functioning is defined by the DSM IV as an IQ range that is between one to two standard deviations below the mean (71functioning is associated with various mental disorders, problems in everyday functioning, social disability and poor academic or occupational achievement. Using data from the Israeli military, we retrieved the social and clinical characteristics of 76,962 adolescents with borderline intellectual functioning and compared their social functioning, psychiatric diagnoses and drug abuse with those of 96,580 adolescents with average IQ (± 0.25 SD from population mean). The results demonstrated that the borderline intellectual functioning group had higher rates of poor social functioning compared to the control group (OR=1.9, 95% CI=1.85-1.94). Individuals with borderline intellectual functioning were 2.37 times more likely to have a psychiatric diagnosis (95% CI=2.30-2.45) and 1.2 times more likely to use drugs (95% CI=1.07-0.35) than those with average IQ. These results suggest that adolescents with borderline intellectual functioning are more likely to suffer from psychiatric disorders, poor social functioning and drug abuse than those with average intelligence, and that borderline intellectual functioning is a marker of vulnerability to these poor outcomes.

    Many centres continue to decline percutaneous lung biopsy (PLB) in patients with poor lung function (particularly FEV1 <1 L) due to the theoretically increased risk of pneumothorax. This practice limits access to novel lung cancer therapies and minimally invasive surgical techniques. Our retrospective single-centre analysis of 212 patients undergoing PLB, all performed prospectively and blinded to lung function, demonstrates that using ambulatory Heimlich valve chest drain (HVCD) to treat significant postbiopsy pneumothorax facilitates safe, diagnostic, early discharge lung biopsy irrespective of lung function with neither FEV1 <1 L nor transfer coefficient for carbon monoxide (TLCO) <40% predicted shown to be independent predictors of HVCD insertion or pneumothorax outcomes. Incorporating ambulatory HVCD into standard PLB practice thereby elegantly bridges the gap that currently exists between tissue diagnosis in patients with poor lung function and the advanced therapeutic options available for this cohort.

    Objective. In developed countries, the functional status scores of patients with poor preoperative scores undergoing total joint replacement (TJR) improve more following TJR than those for patients with better preoperative scores. However, those with better preoperative scores achieve the best postoperative functional outcomes. We determined whether similar associations exist in a developing country. Methods. Dominican patients undergoing total hip or knee replacement completed WOMAC and SF-36 surveys preoperatively and at 12-month follow-up. Patients were stratified into low-, medium- and high-scoring preoperative groups based on their preoperative WOMAC function scores. We examined the associations between the baseline functional status of these groups and two outcomes—improvement in functional status over 12 months and functional status at 12 months—using analysis of variance with multivariable linear regression. Results. Patients who scored the lowest preoperatively made the greatest gains in function and pain relief following their TJRs. However, there were no significant differences in pain or function at 12-month follow-up between patients who scored low and those who scored high on preoperative WOMAC and SF-36 surveys. Conclusion. Patients with poor preoperative functional status had greater improvement but similar 12-month functional outcomes compared with patients who had a higher level of function before surgery. These results suggest that a policy of focusing scarce resources on patients with worse functional status in developing countries may optimize improvement following TJR without threatening functional outcome. Additional research is needed to confirm these findings in other developing countries and to understand why these associations vary between patients in the Dominican Republic and patients from developed countries.

    5-year BC rate was 52% for RP+RT vs. 30% for RP (p < 0.01). The 5-year BC rate for patients with seminal vesicle invasion was 60% for RP+RT vs. 18% for RP (p < 0.01). For those with positive margins, the 5-year BC rate was 64% for RP+RT vs. 27% for RP (p < 0.01). The use of adjuvant RT remained statistically significant on multivariate analysis when applying either biochemical failure definition. Adjuvant RT also remained statistically significant when including the postoperative PSA level (>30 days after surgery) in the multivariate analyses. In addition, 99 (17%) of the 583 RP patients required salvage prostatic fossa RT (median dose, 59.4 Gy) at a median interval of 1.3 years after surgery (range, 0.1-8.4) for a palpable recurrence (n = 10) or a detectable/rising postoperative PSA level (n = 89). The median PSA level before salvage RT was 0.8 ng/mL (mean, 3.2 ng/mL). The 5-year and 8-year BC rate, using the PSA < 0.1 ng/mL definition, from the date of salvage RT was 41% and 35%, respectively. The 5-year and 8-year BC rate, using the PSA < 0.3 ng/mL definition, was 46% and 36%, respectively. The 8-year local recurrence rate after salvage RT was 4%. Conclusion: Adjuvant RT demonstrated improved efficacy against prostate cancer. For patients with poor pathologic features (extracapsular extension, seminal vesicle invasion, positive margins), adjuvant RT improved the biochemical outcome independent of other prognostic factors.

    -to-lymphocyte ratio change (> 1.643) clearly exhibited poorer recurrence-free survival than those who did not (P = 0.009), although no significant correlation was observed between overall survival and the change in the postoperative neutrophil-to-lymphocyte ratio. Based on multivariate analysis, hepatitis B surface antigen positivity, Child-Turcotte-Pugh class B, an elevated postoperative neutrophil-to-lymphocyte ratio change and intra-abdominal infection were significant predictors of poor recurrence-free survival. Hepatic cirrhosis, the maximal tumor diameter and intra-abdominal infection were significant predictors of overall survival. CONCLUSION: Postoperative intra-abdominal infection adversely affected oncologic outcomes, and the change in postoperative neutrophil-to-lymphocyte ratio was a good indicator of tumor recurrence in hepatocellular carcinoma patients after curative hepatectomy.

    Objective Sleep problems are common to patients with bipolar disorder and have been shown to predict subsequent mood symptoms, and have also been shown to lead to worse substance use outcomes in those with substance use disorders. However, the relationship between sleep and clinical outcomes in a population with co-occurring bipolar disorder and substance use disorder is unclear. Method 60 outpatients meeting DSM-IV (SCID) criteria for both bipolar disorder and substance use disorder participated in a randomized trial comparing integrated group therapy for bipolar disorder and substance use disorder to group drug counseling for substance use disorder alone. Poor sleep was assessed with the Pittsburgh Sleep Quality Index, which provides 7 component subscores and an overall sleep score. Results When controlling for baseline mood, substance use, and treatment condition, baseline sleep score predicted mood over the course of treatment and the 6-month follow-up: worse sleep was associated with worse mood outcomes. Sleep was not associated with substance use outcomes. Conclusion Impaired sleep is a prognostic factor for mood outcomes in patients with co-occurring bipolar and substance use disorders. Further investigation is warranted into the long-term clinical outcomes of poor sleep in this population with co-occurring bipolar disorder and substance use disorder so that appropriate interventions can be developed. This clinical trial has been registered in a public trials registry at clinicaltrials.gov (identifier is NCT00227838). PMID:22313797

    Kyriss, T; Lenz, U; Friedel, G

    2016-09-01

    This overview reviews the current literature to compare the functional results after surgical and conservative treatment of patients with flail chest and multiple rib fractures. Regarding functional aspects, patients in the early phase after a thoracic trauma are those that benefit most from the stabilisation of the chest wall by internal fixation of the ribs. Patients recover faster from restrictive respiratory disorders, have less pain and return to the workplace earlier after an operation compared with those that receive conservative treatment. In the medium term, however, patients that are treated conservatively also achieve normal pulmonary function values and become free of pain. The period of convalescence after blunt thoracic trauma is generally underestimated. Future studies of the functional outcome after severe chest injuries should take this into account and the development of functional parameters should be monitored for at least 24 months. A prospective data collection of early and long-term surgical results in registries would be suitable to evaluate benefits and indications of chest wall stabilisation. PMID:27607891

    Stereotype threat research shows that women's math performance can be reduced by activating gender-based math stereotypes. Models of stereotype threat assert that threat reduces cognitive functioning, thereby accounting for its negative effects. This work provides a more detailed understanding of the cognitive processes through which stereotype threat leads women to underperform at math and to take risks, by examining which basic executive functions (inhibition, shifting, and updating) account for these outcomes. In Experiments 1 and 2, women under threat showed reduced inhibition, reduced updating, and reduced math performance compared with women in a control condition (or men); however, only updating accounted for women's poor math performance under threat. In Experiment 3, only updating accounted for stereotype threat's effect on women's math performance, whereas only inhibition accounted for the effect of threat on risk-taking, suggesting that distinct executive functions can account for different stereotype threat-related outcomes.

    A recent systematic review of studies in the developing world has critically examined linkages from familial HIV/AIDS and associated factors such as poverty and child mental health to negative child educational outcomes. In line with several recommendations in the review, the current study modelled relationships between familial HIV/AIDS, poverty, child internalising problems, gender and four educational outcomes: non-enrolment at school, non-attendance, deficits in grade progression and concentration problems. Path analyses reveal no direct associations between familial HIV/AIDS and any of the educational outcomes. Instead, HIV/AIDS-orphanhood or caregiver HIV/AIDS-sickness impacted indirectly on educational outcomes via the poverty and internalising problems that they occasioned. This has implications for evidence-based policy inferences. For instance, by addressing such intervening variables generally, rather than by seeking to target families affected by HIV/AIDS, interventions could avoid exacerbating stigmatisation, while having a more direct and stronger impact on children's educational outcomes. This analytic approach also suggests that future research should seek to identify causal paths, and may include other intervening variables related to poverty (such as child housework and caring responsibilities) or to child mental health (such as stigma and abuse), that are linked to both familial HIV/AIDS and educational outcomes.

    We examine the metallicity distribution function (MDF) and fraction of carbon-enhanced metal-poor (CEMP) stars in a sample that includes 86 stars with [Fe/H] <= -3.0, based on high-resolution, high signal-to-noise spectroscopy, of which some 32 objects lie below [Fe/H] = -3.5. After accounting for the completeness function, the "corrected" MDF does not exhibit the sudden drop at [Fe/H] = -3.6 that was found in recent samples of dwarfs and giants from the Hamburg/ESO survey. Rather, the MDF decreases smoothly down to [Fe/H] = -4.1. Similar results are obtained from the "raw" MDF. We find that the fraction of CEMP objects below [Fe/H] = -3.0 is 23% ± 6% and 32% ± 8% when adopting the Beers & Christlieb and Aoki et al. CEMP definitions, respectively. The former value is in fair agreement with some previous measurements, which adopt the Beers & Christlieb criterion. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile. Based on observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere, Chile (proposal 281.D-5015).

    We examine the metallicity distribution function (MDF) and fraction of carbon-enhanced metal-poor (CEMP) stars in a sample that includes 86 stars with [Fe/H] {<=} -3.0, based on high-resolution, high signal-to-noise spectroscopy, of which some 32 objects lie below [Fe/H] = -3.5. After accounting for the completeness function, the 'corrected' MDF does not exhibit the sudden drop at [Fe/H] = -3.6 that was found in recent samples of dwarfs and giants from the Hamburg/ESO survey. Rather, the MDF decreases smoothly down to [Fe/H] = -4.1. Similar results are obtained from the 'raw' MDF.

    No nutrition assessment tools specifically tailored for intensive care unit (ICU) patients have been developed and validated in Singapore. Studies conducted in Brazilian populations suggest that the thickness of the adductor pollicis muscle (TAPM) may be used to assess nutritional status and predict mortality of critically ill patients. The aim of this study was to determine if TAPM can be used as a predictive indicator of mortality in Singapore ICU patients. TAPM values were obtained using skinfold calipers in 229 patients admitted to the medical ICU. TAPM measured in both hands showed no significant correlation with either the primary outcome (28-day mortality) or secondary outcomes (hospital outcome and hospital length of stay). This study demonstrated that TAPM does not predict 28-day mortality and hospital outcome, and is not correlated to length of stay in Singapore ICU patients. More studies are necessary to validate the use of TAPM as an anthropometric indicator of ICU outcome in other regions of the world. PMID:26693744

    High mobility group AT-hook 2 (HMGA2) is involved in a wide spectrum of biological processes and is upregulated in several tumors. Here, we collected 273 breast cancer (BC) specimens as a training set and 310 specimens as a validation set to examine the expression of HMGA2 by immunohistochemical staining. It was found that HMGA2 expression was significantly positively correlated with advanced tumor grade and poor survival. Subgroup analysis indicated that high level of HMGA2 was significantly correlated with poor prognosis, especially in the subgroups of stage II-III, low pathological grade and non-triple negative breast cancer cases. Gene set enrichment analysis (GSEA) demonstrated a significant positive correlation between HMGA2 level and the gene expression signature of metaplastic and mesenchymal phenotype. Importantly, we also observed that ectopic expression of HMGA2 promoted the migration and invasion of breast cancer cells, and protected cancer cells against genotoxic stress from agents stimulating P53 (Ser15) phosphorylation. As a conclusion, expression of HMGA2 might indicate more advanced malignancy of breast cancer. Thus we believe HMGA2 could serve as a biomarker of poor prognosis and a novel target in treating BC tumors. PMID:27063096

    Objective A burgeoning area of research has focused on motivational deficits in schizophrenia, producing hypotheses about the role that motivation plays in the well-known relationship between neurocognition and functional outcome. However, little work has examined the role of motivation in more complex models of outcome that include social cognition, despite our increased understanding of the critical role of social cognition in community functioning in schizophrenia, and despite new basic science findings on the association between social cognitive and reward processing in neural systems in humans. Using path analysis, we directly contrasted whether motivation 1) causally influences known social cognitive deficits in schizophrenia, leading to poor outcome or 2) mediates the relationship between social cognitive deficits and outcome in this illness. Method Ninety one patients with schizophrenia or schizoaffective disorder completed interview-based measures of motivation and functional outcome as well as standardized measures of neurocognition and social cognition in a cross-sectional design. Results In line with recent research, motivation appears to mediate the relationship between neurocognition, social cognition and functional outcome. A model with motivation as a causal factor resulted in poor fit indicating that motivation does not appear to precede neurocognition. Conclusions Findings in the present study indicate that motivation plays a significant and mediating role between neurocognition, social cognition, and functional outcome. Potential psychosocial treatment implications are discussed, especially those that emphasize social cognitive and motivational enhancement. PMID:19783407

    2016-01-01

    Background and Objectives Hospitals with high complex oncologic surgical volume have improved short-term outcomes. However, for long-term outcomes, the influence of other therapies must be considered. We compared effects of resection with other therapies on long-term outcomes across U.S. hospitals. Methods We examined claims in the Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset for patients with esophageal (EC) and pancreatic (PC) cancers between 2005–2009, with follow-up through 2011, performing multivariable Cox proportional hazards analyses. We stratified hospitals by volume and compared rates of treatments in the context of survival. Results We studied 905 EC and 3,293 PC patients at 138 and 375 hospitals, respectively. For EC, resection rates were significantly higher (32.9% vs. 9.5%, P<0.001) in the highest versus lowest volume hospitals. Adjusted survival was also statistically significantly better (48.5% vs. 43.1%, P<0.001). For PC, resection rates were also statistically significantly higher (30.1% vs. 12.0%, P<0.001) with higher adjusted survival (21.5% vs. 19.9%, P = 0.01). We did not find variation in rates of other cancer treatments across hospitals. Conclusions A significant association exists between long-term survival and rates of cancer-directed surgery across hospitals, without variation in rates of other therapies. Access to resection appears to be key to reducing variation in long-term survival. PMID:26953166

    Background Tuberculosis (TB) represents a major global health problem. The prognosis of clinically active tuberculosis depends on the complex interactions between Mycobacterium tuberculosis (Mtb) and its host. In recent years, autophagy receives particular attention for its role in host defense against intracellular pathogens, including Mtb. In present study, we aim to investigate the relationship of autophagy induction by clinical isolates of Mtb with the clinical outcomes in patients with TB. Methodology/Principal Findings We collected 185 clinical isolates of Mtb, and determined the effect of these Mtb isolates on autophagy induction in macrophages. It was found that most of clinical isolates of Mtb were able to induce autophagosome formation in macrophages, however, the autophagy-inducing ability varied significantly among different isolates. Of importance, our results revealed that patients infected by Mtb with poor autophagy-inducing ability displayed more severe radiographic extent of disease (p<0.001), and were more likely to have unfavorable treatment outcomes (p<0.001). No significant association was observed between the extent of Mtb-induced autophagy with some socio-demographic characteristics (such as gender, age and tobacco consumption), and some laboratory tests (such as hemoglobin, leukocyte count and erythrocyte sedimentation rate). Furthermore, results from logistic regression analysis demonstrated that the defect in autophagy induction by clinical isolates of Mtb was an independent risk factor for far-advanced radiographic disease (aOR 4.710 [1.93–11.50]) and unfavorable treatment outcomes (aOR 8.309 [2.22–28.97]) in TB. Conclusion/Significance These data indicated that the defect in autophagy induction by Mtb isolates increased the risk of poor clinical outcomes in TB patients, and detection of clinical isolates-induced autophagosome formation might help evaluate the TB outcomes.

    Recent research has suggested that high quality child care can buffer young children against poorer cognitive and language outcomes when they are at risk for poorer language and readiness skills. Most of this research measured the quality of parenting and the quality of the child care with global observational measures or rating scales that did not specify the exact maternal or caregiver behaviors that might be causally implicated in the buffering of these children from poor outcomes. The current study examined the actual language by the mother to her child in the home and the verbal interactions between the caregiver and child in the child care setting that might be implicated in the buffering effect of high quality childcare. The sample included 433 rural children from the Family Life Project who were in child care at 36 months of age. Even after controlling for a variety of covariates, including maternal education, income, race, child previous skill, child care type, the overall quality of the home and quality of the child care environment; observed positive caregiver-child verbal interactions in the child care setting interacted with the maternal language complexity and diversity in predicting children’s language development. Caregiver-child positive verbal interactions appeared to buffer children from poor language outcomes concurrently and two years later if children came from homes where observed maternal language complexity and diversity during a picture book task was less.

    2016-01-01

    Obesity has reached epidemic proportions and is a contributor to many adverse health outcomes, including increased risk for dementia and adverse structural and functional brain changes. Milder forms of cognitive impairment in multiple domains can also be found in obese individuals of all ages that are believed to stem from brain abnormalities long prior to onset of neurological conditions such as dementia. However, the mechanisms for adverse brain changes and subsequent cognitive dysfunction in obesity are complex and poorly understood. This paper proposes a possible etiological model for obesity associated cognitive impairment with emphasis on the role of poor glycemic control and conditions like type 2 diabetes mellitus. Clinical implications associated with treatment of obesity in persons with cognitive deficits in addition to the cognitive promoting effects of weight loss surgery are also discussed. PMID:24752836

    The subventricular zone (SVZ) has been implicated in the origination, development, and biological behavior of gliomas. Tumor-SVZ contact is also postulated to be a poor prognostic factor in glioblastomas. We aimed to evaluate the prognostic consequence of the anatomical involvement of low-grade gliomas with the SVZ. To that end, we reviewed 143 patients with diffuse astrocytomas, and tumor lesions were manually delineated on magnetic resonance images. We initially investigated the prognostic role of SVZ contact in all patients. Additionally, we investigated the influence of the anatomical proximity of the tumor lesion centroids to the SVZ in the SVZ-involved patient cohorts, as well as location within the SVZ. We found SVZ contact with tumors to be a significant prognostic factor of overall survival in all patients with diffuse astrocytomas (p = 0.027). In the SVZ-involved cohort, a shorter distance from the tumor centroid to the SVZ (≤30 mm) correlated with shorter overall survival (p = 0.022) on univariate analysis. However, there was no significant difference in overall survival with respect to the SVZ region involved with the tumor (p = 0.930). Multivariate analysis showed that a shorter distance between the tumor centroid and the SVZ (p = 0.039) was significantly associated with poor overall survival in SVZ-involved patients. Hence, this study helps establish the prognostic role of the anatomical interaction of tumors with the SVZ in low-grade astrocytomas. PMID:27120204

    Functional dysphonia (FD) refers to a voice problem in the absence of a physical condition. It is a multifaceted voice disorder. There is no consensus with regard to its definition and inclusion criteria for diagnosis. FD has many predisposing and precipitating factors, which may include genetic susceptibility, psychological traits, and the vocal behavior itself. The assessment of voice disorders should be multidimensional. In addition to the clinical examination, auditory-perceptual, acoustic, and self-assessment analyses are very important. Self-assessment was introduced in the field of voice 25 years ago and has produced a major impact in the clinical and scientific scenario. The choice of treatment for FD is vocal rehabilitation by means of direct therapy; however, compliance has been an issue, except for cases of functional aphonia or when an intensive training is administered. Nevertheless, there are currently no controlled studies that have explored the different options of treatment regimens for these patients. Strategies to improve patient outcome involve proper multidisciplinary diagnosis in order to exclude neurological and psychiatric disorders, careful voice documentation with quantitative measurement and qualitative description of the vocal deviation for comparison after treatment, acoustic evaluation to gather data on the mechanism involved in voice production, self-assessment questionnaires to map the impact of the voice problem on the basis of the patient's perspective, referral to psychological evaluation in cases of suspected clinical anxiety and/or depression, identification of dysfunctional coping strategies, self-regulation data to assist patients with their vocal load, and direct and intensive vocal rehabilitation to reduce psychological resistance and to reassure patient's recovery.

    Background Visceral leishmaniasis (VL) coinfection with HIV/AIDS most often results in unfavorable responses to treatment, frequent relapses, and premature deaths. Scarce data are available, regarding the magnitude and poor treatment outcomes of VL-HIV coinfection. Objective The main objective of this systematic review was to describe the pooled prevalence of VL and poor treatment outcome among HIV patients. Review methods Electronic databases mainly PubMed were searched. Databases, such as Google and Google scholar, were searched for gray literature. Articles were selected based on their inclusion criterion, whether they included HIV-positive individuals with VL diagnosis. STATA 11 software was used to conduct a meta-analysis of pooled prevalence of VL-HIV coinfection. Results Fifteen of the 150 articles fulfilled the inclusion criteria. A majority of the study participants were males between 25 years and 41 years of age. The pooled prevalence of VL-HIV coinfection is 5.2% with 95% confidence interval of (2.45–10.99). Two studies demonstrated the impact of antiretroviral treatment on reduction in relapse rate compared with patients who did not start antiretroviral treatment. One study showed that the higher the baseline CD4+ cell count (>100 cells/mL) the lower the relapse rate. Former VL episodes were identified as risk factors for relapse in two articles. In one of the articles, an earlier bout of VL remains significant in the model adjusted to other variables. Conclusion The pooled prevalence of VL in HIV-infected patients is low and an earlier bout of VL and CD4+ count <100 cells/mL at the time of primary VL diagnosis are factors that predict poor treatment outcome.

    Background. Patients with hematologic malignancy (HM) often require intensive care unit (ICU) admission due to organ failure through disease progression or treatment-related complications. Objective. To determine mortality and prognostic variables in adult patients with HM who were admitted to ICU. Methods. Structured chart review of all adult patients (age ≥ 18 years) with HM admitted to ICU of a Canadian tertiary care hospital between 2004 and 2014. Outcome measures included mortality (ICU, 30-day, 60-day, and 12-month). Logistic regression was performed to determine predictors of mortality. Results. Overall, there were 206 cases of HM admitted to the ICU during the study (mean age: 51.3 ± 13.6 years; 60% male). Median stay was 3 days, with 14.1% requiring prolonged ICU admission. ICU mortality was 45.6% and increased to 59.2% at 30 days, 62.6% at 60 days, and 74.3% at 12 months. Predictors of increased ICU mortality included mechanical ventilation requirement and vasopressor therapy requirement, while admission to ICU postoperatively and having myeloma were associated with decreased mortality. Conclusions. Patients admitted to ICU with HM have high mortality (45.6%), which increased to 74.3% at 1 year. Analysis of multiple variables identified critical illness, postsurgical admission, and myeloma as predictors of patient outcomes. PMID:27445571

    The aim of this study was to describe risk factors for delirium and the impact of delirium on the rehabilitation outcome for patients operated for femoral neck fractures. Sixty-one patients, aged 70 years or older, consecutively admitted to the Department of Orthopaedic Surgery at Umeå University Hospital, Sweden for femoral neck fractures were assessed and interviewed during hospitalization and at follow up 4 months after surgery. Delirium occurred in 38 (62%) patients and those who developed delirium were more often demented and/or depressed. Patients with delirium were longer hospitalized and they were more dependent in their activity of daily living (ADL) on discharge and after 4 months. They had poorer psychological well-being and more medical complications than the nondelirious. A large proportion of the patients who developed delirium did not regain their previous walking ability and could not return to their prefracture living accommodation. Delirium after hip fracture surgery is very common especially among patients with dementia or depression. This study shows that delirium has a serious impact on the rehabilitation outcome from both short- and long-term perspectives. Because delirium can be prevented and treated, it is important to improve the care of elderly patients with hip fractures. PMID:15877637

    The patient-centered medical home (PCMH) is an integrated primary care delivery model particularly suited for patients with poor diabetes control. Although PCMH models targeting adults with diabetes have shown some early success, little is known about the long-term benefits of medical homes in terms of health and cost outcomes. The performance of a PCMH model in adults with poor diabetes control was assessed using simulated controlled trial data obtained from the Archimedes model of disease progression and health care utilization. Using the Cardio-Metabolic Risk data set, we compared health and cost outcomes over a 20-year period between adults with poor diabetes control (HbA1c >9%) receiving standard care and these same adults receiving care under a PCMH model with a 49% HbA1c intervention improvement rate at a per-beneficiary per-month care management cost of $20 per month. The results suggest that the PCMH model has the potential to not only reduce the proportion of the population with bilateral blindness, foot amputations, and myocardial infarctions-and the mortality rate-but it can also do so in a cost-effective manner ($7898 per quality-adjusted life year). The PCMH model is cost saving for the population 50 to 64 years old and it is particularly cost-effective for men ($883 per quality-adjusted life year). Moreover, these effects are relatively large for adults 30 to 49 years old (lower bilateral blindness and death rates), women (lower foot amputation and death rates), and men (lower bilateral blindness and myocardial infarction rates). The PCMH model has potential long-term benefits to both patients with poor diabetes control as well as health care systems and providers willing to invest in this health care delivery approach.

    A prospective cohort study was done to evaluate the role of surgery in patients with spontaneous supratentorial intracerebral haemorrhage (SICH) and to identify predictors of outcome including the use of invasive regional cortical cerebral blood flow (rCoBF) and microdialysis. Surgery consisted of craniotomy or decompressive craniectomy. The ventriculostomy for intracranial pressure (ICP) monitoring and drainage and regional cortical cerebral blood flow (rCoBF) and microdialysis were performed in all subjects. Pre and post operative information on subjects were collected. The study end points was functional outcome at 6 months based on a dichotomised Glasgow Outcome Scale (GOS).The selected clinical, radiological, biochemical and treatment factors that may influence the functional outcome were analysed for their significance. A total of 36 patients were recruited with 27(75%) patients had Glasgow Coma Score (GCS) between 5 to 8 on admission and 9(25%) were admitted with GCS of 9. At 6 months, 86 % had a poor or unfavourable outcome (GOS I–III) and 14% had good or favourable outcome (GOS IV–V). The mortality rate at 6 months was 55%. Univariate analysis for the functional outcome identified 2 significant variables, the midline shift (p=0.013) and mean lactate:pyruvate ratio (p=0.038). Multivariate analysis identified midline shift as the single significant independent predictor of functional outcome (p=0.013).Despite aggressive regional cortical cerebral blood flow (rCoBF) and microdialysis study for detection of early ischemia, surgical treatment for spontaneous intracerebral haemorrhage only benefited a small number of patients in terms of favourable outcome (14%) and in the majority of patients (86%), the outcome was unfavourable. Patients with midline shift > 5mm has almost 21 times higher chances (adj) OR 20.8 of being associated with poor outcome (GOS I–III). PMID:22589638

    Purpose To analyze the baseline clinicopathologic characteristics of prostate tumors with germline BRCA1 and BRCA2 (BRCA1/2) mutations and the prognostic value of those mutations on prostate cancer (PCa) outcomes. Patients and Methods This study analyzed the tumor features and outcomes of 2,019 patients with PCa (18 BRCA1 carriers, 61 BRCA2 carriers, and 1,940 noncarriers). The Kaplan-Meier method and Cox regression analysis were used to evaluate the associations between BRCA1/2 status and other PCa prognostic factors with overall survival (OS), cause-specific OS (CSS), CSS in localized PCa (CSS_M0), metastasis-free survival (MFS), and CSS from metastasis (CSS_M1). Results PCa with germline BRCA1/2 mutations were more frequently associated with Gleason ≥ 8 (P = .00003), T3/T4 stage (P = .003), nodal involvement (P = .00005), and metastases at diagnosis (P = .005) than PCa in noncarriers. CSS was significantly longer in noncarriers than in carriers (15.7 v 8.6 years, multivariable analyses [MVA] P = .015; hazard ratio [HR] = 1.8). For localized PCa, 5-year CSS and MFS were significantly higher in noncarriers (96% v 82%; MVA P = .01; HR = 2.6%; and 93% v 77%; MVA P = .009; HR = 2.7, respectively). Subgroup analyses confirmed the poor outcomes in BRCA2 patients, whereas the role of BRCA1 was not well defined due to the limited size and follow-up in this subgroup. Conclusion Our results confirm that BRCA1/2 mutations confer a more aggressive PCa phenotype with a higher probability of nodal involvement and distant metastasis. BRCA mutations are associated with poor survival outcomes and this should be considered for tailoring clinical management of these patients. PMID:23569316

    Primary hepatopathies are a common cause of morbidity and mortality in dogs. The underlying aetiology of most cases of canine hepatitis is unknown. Consequently, treatments are typically palliative and it is difficult to provide accurate prognostic information to owners. In human hepatology there is accumulating data which indicates that the presence of systemic inflammatory response syndrome (SIRS) is a common and debilitating event in patients with liver diseases. For example, the presence of SIRS has been linked to the development of complications such as hepatic encephalopathy (HE) and is associated with a poor clinical outcome in humans with liver diseases. In contrast, the relationship between SIRS and clinical outcome in dogs with a primary hepatitis is unknown. Seventy dogs with histologically confirmed primary hepatitis were enrolled into the study. Additional clinical and clinicopathological information including respiratory rate, heart rate, temperature, white blood cell count, sodium, potassium, sex, presence of ascites, HE score, alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin and red blood cell concentration were available in all cases. The median survival of dogs with a SIRS score of 0 or 1 (SIRS low) was 231 days compared to a median survival of 7 days for dogs with a SIRS score of 2, 3 or 4 (SIRS high) (p<0.001). A Cox proportional hazard model, which included all other co-variables, revealed that a SIRS high score was an independent predictor of a poor clinical outcome. The effect of modulating inflammation on treatment outcomes in dogs with a primary hepatitis is deserving of further study. PMID:26808672

    A considerable proportion of all women undergoing IVFrespond poorly to gonadotropin stimulation. These women are reported to be associated with increased cancellation rates and lower pregnancy rates. It has been hypothesized that poor response to ovarian stimulation is a first sign of ovarian ageing or premature ovarian failure, which might be related to altered inflammatory response in the body. We aimed to compare follicular fluid presepsin levels between poor- and normo-responder patients to ovarian stimulation, to assess its relationship with reproductive outcomes. This study included infertility patients who underwent ovulation induction with either long GnRH agonist or GnRH antagonist protocols and who subsequently underwent IVF/ICSI. Included patients were assigned to two groups according to the Bologna criteria for poor ovarian response. Group 1 and 2 consisted of normo- and poor-responder patients, respectively.The 2 groups were compared in terms of FF presepsin levels. Also, any relationship between the FF presepsin levels and fertility outcomes was assessed within the groups. The groups were compared by using student’s t-test, Mann-Whitney U test and X2 test, where appropriate. Pregnancy rates were not significantly different between the groups (22.6% and 17.6%; P=0.650, respectively). FF presepsin levels were higher in Group 1, however, the difference was not statistically significant (298.0±797.4 and 149.2±422.3; P=0.190, respectively). FF presepsin levels did not significantly differ between pregnancy positive and the pregnancy negative patients in both Group 1 (243.6±531.1 and 314.3±866.5; P=0.055, respectively) and Group 2 (112.2±79.8 and 157.1±464.3; P=0.394, respectively). Consequently, FF presepsin seems not to be a reliable marker in predicting pregnancy in both normo-responder and poor-responder infertility groups. PMID:26309683

    Background The importance of maternal sanitation behaviour during pregnancy for birth outcomes remains unclear. Poor sanitation practices can promote infection and induce stress during pregnancy and may contribute to adverse pregnancy outcomes (APOs). We aimed to assess whether poor sanitation practices were associated with increased risk of APOs such as preterm birth and low birth weight in a population-based study in rural India. Methods and Findings A prospective cohort of pregnant women (n = 670) in their first trimester of pregnancy was enrolled and followed until birth. Socio-demographic, clinical, and anthropometric factors, along with access to toilets and sanitation practices, were recorded at enrolment (12th week of gestation). A trained community health volunteer conducted home visits to ensure retention in the study and learn about study outcomes during the course of pregnancy. Unadjusted odds ratios (ORs) and adjusted odds ratios (AORs) and 95% confidence intervals for APOs were estimated by logistic regression models. Of the 667 women who were retained at the end of the study, 58.2% practiced open defecation and 25.7% experienced APOs, including 130 (19.4%) preterm births, 95 (14.2%) births with low birth weight, 11 (1.7%) spontaneous abortions, and six (0.9%) stillbirths. Unadjusted ORs for APOs (OR: 2.53; 95% CI: 1.72–3.71), preterm birth (OR: 2.36; 95% CI: 1.54–3.62), and low birth weight (OR: 2.00; 95% CI: 1.24–3.23) were found to be significantly associated with open defecation practices. After adjustment for potential confounders such as maternal socio-demographic and clinical factors, open defecation was still significantly associated with increased odds of APOs (AOR: 2.38; 95% CI: 1.49–3.80) and preterm birth (AOR: 2.22; 95% CI: 1.29–3.79) but not low birth weight (AOR: 1.61; 95% CI: 0.94–2.73). The association between APOs and open defecation was independent of poverty and caste. Even though we accounted for several key

    The effective evaluation and management of orthopaedic conditions including shoulder disorders relies upon understanding the level of disability created by the disease process. Validated outcome measures are critical to the evaluation process. Traditionally, outcome measures have been physician derived objective evaluations including range of motion and radiologic evaluations. However, these measures can marginalize a patient’s perception of their disability or outcome. As a result of these limitations, patient self-reported outcomes measures have become popular over the last quarter century and are currently primary tools to evaluate outcomes of treatment. Patient reported outcomes measures can be general health related quality of life measures, health utility measures, region specific health related quality of life measures or condition specific measures. Several patients self-reported outcomes measures have been developed and validated for evaluating patients with shoulder disorders. Computer adaptive testing will likely play an important role in the arsenal of measures used to evaluate shoulder patients in the future. The purpose of this article is to review the general health related quality-of-life measures as well as the joint-specific and condition specific measures utilized in evaluating patients with shoulder conditions. Advances in computer adaptive testing as it relates to assessing dysfunction in shoulder conditions will also be reviewed. PMID:25405091

    Leiomyosarcoma is an aggressive soft tissue sarcoma with poor patient survival. Recently, it was shown that 53% to 62% of leiomyosarcomas use the alternative lengthening of telomeres (ALT) as their telomere maintenance mechanism. The molecular basis of this mechanism has not been elucidated. Studies of pancreatic neuroendocrine tumor have suggested that the inactivation of either α-thalassemia/mental retardation syndrome X-linked (ATRX) or death domain-associated (DAXX) protein is associated with the ALT phenotype. In this study, we sought to determine the clinicopathologic features of leiomyosarcoma with the ALT phenotype and the possible relationship between this phenotype and ATRX/DAXX expression. Telomerase reverse transcriptase gene (TERT) promoter mutation analysis was also performed. Ninety-two leiomyosarcomas derived from the uterus, retroperitoneum/intra-abdomen, and various other sites were analyzed. Telomere-specific fluorescence in situ hybridization revealed that 59% (51/86) of leiomyosarcomas had the ALT phenotype. Loss of ATRX expression was observed in 33% of the tumors (30/92), and all but 2 ATRX-deficient tumors were ALT positive. Both the ALT phenotype and loss of ATRX expression were associated with epithelioid/pleomorphic cell morphology, tumor necrosis, and poor differentiation. None of the 92 cases lost DAXX expression. No TERT promoter mutation was detected (n=39). For survival analysis, poor differentiation, high FNCLCC grade, tumor size, and ALT phenotype were correlated with poor overall survival in univariate analysis. Tumor size and ALT phenotype remained independent prognostic factors in multivariate analysis. We concluded that the ALT phenotype in the leiomyosarcoma is associated with aggressive histologic features, loss of ATRX expression, and poor clinical outcome. PMID:25229770

    Juvenile myelomonocytic leukemia (JMML), an overlap of myelodysplastic / myeloproliferative neoplasm, is an intractable pediatric myeloid neoplasm. Epigenetic regulation of transcription, particularly by CpG methylation, plays an important role in tumor progression, mainly by repressing tumor-suppressor genes. To clarify the clinical importance of aberrant DNA methylation, we studied the hypermethylation status of 16 target genes in the genomes of 92 patients with JMML by bisulfite conversion and the pryosequencing technique. Among 16 candidate genes, BMP4, CALCA, CDKN2A, and RARB exhibited significant hypermethylation in 72% (67/92) of patients. Based on the number of hypermethylated genes, patients were stratified into three cohorts based on an aberrant methylation score (AMS) of 0, 1–2, or 3–4. In the AMS 0 cohort, the 5-year overall survival (OS) and transplantation-free survival (TFS) were good (69% and 76%, respectively). In the AMS 1–2 cohort, the 5-year OS was comparable to that in the AMS 0 cohort (68%), whereas TFS was poor (6%). In the AMS 3–4 cohort, 5-year OS and TFS were markedly low (8% and 0%, respectively). Epigenetic analysis provides helpful information for clinicians to select treatment strategies for patients with JMML. For patients with AMS 3–4 in whom hematopoietic stem cell transplantation does not improve the prognosis, alternative therapies, including DNA methyltransferase inhibitors and new molecular-targeting agents, should be established as treatment options.

    Diabetic patients who lack access to primary care tend to frequent the ED, often with complications from their disease that could have been prevented with proper management and education. To get around the problem of access, researchers tested an automated program that continuously delivered educational messaging via text to a group of patients who presented to the ED with poorly controlled diabetes. After six months, researchers noted improvements in Hb A1c levels, self-reported medication adherence, and ED utilization when compared with a control group. And the impact was particularly noteworthy among Latinos, according to the researchers. The text messaging program, dubbed TExT-Med, was developed by four physicians and two diabetes educators. The messages were delivered daily, and contained educational as well motivational content derived from the National Diabetes Education Program.There were also medication reminders, healthy living challenges, and trivia questions about diabetes. At six months, Hb A1c levels decreased by 1.05% in the intervention group, compared to 0.60% in the control group, and self-reported medication adherence improved from 4.5 to 5.4 (as measured on an 8 point scale) in the intervention group versus a decrease of 0.1 in the control group. During the six-month study period, 35.9% of patients in the intervention group presented to the ED for care, as compared to 51.6% of patients in the control group. PMID:24505864

    Clinical significance of 2,3-dioxygenase (IDO) has been studied in types of tumors, but the role that IDO played in gastric adenocarcinoma (GAC) is still unclear. Here, we aim to investigate the prognostic value of IDO expression in patients with GAC. We examined intratumoral IDO expression in retrospectively enrolled 357 patients with GAC undergoing gastrectomy at Zhongshan Hospital of Fudan University in 2008 by immunohistochemical staining. The Kaplan-Meier method and Cox regression models were used to evaluate the prognostic value of IDO expression and its association with clinical pathological factors. We generated a predictive nomogram by integrating IDO expression with the TNM staging system for overall survival of GAC patients. High expression of intratumoral IDO predicted a dismal outcome. Intratumoral IDO expression gave a further discrimination for the prognosis of GAC patients. By Cox multivariate analysis, IDO expression was defined as an independent prognosticator. The generated nomogram performed well in predicting the 3- and 5-year overall survival of GAC patients. Conclusively, IDO is a potential prognostic biomarker for overall survival of patients with GAC after gastrectomy. PMID:26887337

    Although TP53, NOTCH1, and SF3B1 mutations may impair prognosis of patients with chronic lymphocytic leukemia (CLL) receiving frontline therapy, the impact of these mutations or any other, alone or in combination, remains unclear at relapse. The genome of 114 relapsed/refractory patients included in prospective trials was screened using targeted next-generation sequencing of the TP53, SF3B1, ATM, NOTCH1, XPO1, SAMHD1, MED12, BIRC3, and MYD88 genes. We performed clustering according to both number and combinations of recurrent gene mutations. The number of genes affected by mutation was ≥ 2, 1, and 0 in 43 (38%), 49 (43%), and 22 (19%) respectively. Recurrent combinations of ≥ 2 mutations of TP53, SF3B1, and ATM were found in 22 (19%) patients. This multiple-hit profile was associated with a median progression-free survival of 12 months compared with 22.5 months in the remaining patients (P = .003). Concurrent gene mutations are frequent in patients with relapsed/refractory CLL and are associated with worse outcome. PMID:26316624

    Objective Determine predictors of neurocognitive outcome in early school age congenital diaphragmatic hernia (CDH) survivors. Study design Prospective study of infants with CDH at Duke University Medical Center. Neurocognitive delay (NCD) at school age (4 to 7 years) was defined as a score < 80 in any of the following areas: Verbal Scale IQ, Performance Scale IQ, Expressive Language, or Receptive Language. Logistic regression, Fisher’s exact, and the Wilcoxon rank sum test were used to examine the relationship between NCD at early school age and 6 demographic and 18 medical variables. Results Of 43 infants with CDH, twenty seven (63%) survived to hospital discharge, and 16 (59%) returned for school age testing at a median age of 4.9 years. Seven (44%) of the children evaluated had NCD. Patch repair (p=0.01), extracorporeal membrane oxygenation (ECMO; p=0.02), days on ECMO (p=0.01), days of mechanical ventilation (p=0.049), and post-operative use of inhaled nitric oxide (p=0.02) were found to be associated with NCD at early school age. Conclusions CDH survivors are at risk for neurocognitive delay persisting into school age. Perinatal factors such as patch repair and ECMO treatment may aid in identifying CDH survivors at high risk for continued learning difficulties throughout childhood. PMID:23583126

    Natriuretic peptides (BNP and NT-proBNP) are recognized as gold-standard predictive markers in Heart Failure (HF). However, currently ST2 (member of the interleukin 1 receptor family) has emerged as marker of inflammation, fibrosis and cardiac stress. We evaluated ST2 and CRP as prognostic markers in 178 patients with chronic heart failure in comparison with other classical markers such as clinical established parameters but also biological markers: NT-proBNP, hs-cTnT alone or in combination. In multivariate analysis, subsequent addition of ST2 led to age, CRP and ST2 as the only remaining predictors of all-cause mortality (HR 1.03, HR 1.61 and HR 2.75, respectively) as well as of cardiovascular mortality (HR 1.00, HR 2.27 and HR 3.78, respectively). The combined increase of ST2 and CRP was significant for predicting worsened outcomes leading to identify a high risk subgroup that individual assessment of either marker. The same analysis was performed with ST2 in combination with Barcelona score. Overall, our findings extend previous data demonstrating that ST2 in combination with CRP as a valuable tool for identifying patients at risk of death. PMID:27311068

    Placental malaria is caused by Plasmodium falciparum–infected erythrocytes that bind to placental tissue. Binding is mediated by VAR2CSA, a parasite antigen coded by the var gene, which interacts with chondroitin sulfate A (CSA). Consequences include maternal anemia and fetal growth retardation. Antibody-mediated immunity to placental malaria is acquired during successive pregnancies, but the target of VAR2CSA-specific protective antibodies is unclear. We assessed VAR2CSA-specific antibodies in pregnant women and analyzed their relationships with protection against placental infection, preterm birth, and low birthweight. Antibody responses to the N-terminal region of VAR2CSA during early pregnancy were associated with reduced risks for infections and low birthweight. Among women infected during pregnancy, an increase in CSA binding inhibition was associated with reduced risks for placental infection, preterm birth, and low birthweight. These data suggest that antibodies against VAR2CSA N-terminal region mediate immunity to placental malaria and associated outcomes. Our results validate current vaccine development efforts with VAR2CSA N-terminal constructs. PMID:25898123

    Background The epidemiological evidence linking socioeconomic deprivation with adverse pregnancy outcomes has been conflicting mainly due to poor measurement of socioeconomic status (SES). Studies have also failed to evaluate the plausible pathways through which socioeconomic disadvantage impacts on pregnancy outcomes. We investigated the importance of maternal SES as determinant of birth weight and gestational duration in an urban area and evaluated main causal pathways for the influence of SES. Methods A population-based cross-sectional study was conducted among 559 mothers accessing postnatal services at the four main health facilities in Cape Coast, Ghana in 2011. Information on socioeconomic characteristics of the mothers was collected in a structured questionnaire. Results In multivariate linear regression adjusting for maternal age, parity and gender of newborn, low SES resulted in 292 g (95% CI: 440–145) reduction in birth weight. Important SES-related determinants were neighborhood poverty (221 g; 95% CI: 355–87), low education (187 g; 95% CI: 355–20), studentship during pregnancy (291 g; 95% CI: 506–76) and low income (147 g; 95% CI: 277–17). In causal pathway analysis, malaria infection (6–20%), poor nutrition (2–51%) and indoor air pollution (10–62%) mediated substantial proportions of the observed effects of socioeconomic deprivation on birth weight. Generalized linear models adjusting for confounders indicated a 218% (RR: 3.18; 95% CI: 1.41–7.21) risk increase of LBW and 83% (RR: 1.83; 95% CI: 1.31–2.56) of PTB among low income mothers. Low and middle SES was associated with 357% (RR: 4.57; 95% CI: 1.67–12.49) and 278% (RR: 3.78; 95% CI: 1.39–10.27) increased risk of LBW respectively. Malaria infection, poor nutrition and indoor air pollution respectively mediated 10–21%, 16–44% and 31–52% of the observed effects of socioeconomic disadvantage on LBW risk.

    Biomarker studies for early detection of acute kidney injury (AKI) have been limited by nonselective testing and uncertainties in using small changes in serum creatinine as a reference standard. Here we examine the ability of urine L-type fatty acid-binding protein (L-FABP), neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), and kidney injury molecule-1 (KIM-1) to predict injury progression, dialysis, or death within 7 days in critically ill adults with early AKI. Of 152 patients with known baseline creatinine examined, 36 experienced the composite outcome. Urine L-FABP demonstrated an area under the receiver-operating characteristic curve (AUC-ROC) of 0.79 (95% confidence interval 0.70-0.86), which improved to 0.82 (95% confidence interval 0.75-0.90) when added to the clinical model (AUC-ROC of 0.74). Urine NGAL, IL-18, and KIM-1 had AUC-ROCs of 0.65, 0.64, and 0.62, respectively, but did not significantly improve discrimination of the clinical model. The category-free net reclassification index improved with urine L-FABP (total net reclassification index for nonevents 31.0%) and urine NGAL (total net reclassification index for events 33.3%). However, only urine L-FABP significantly improved the integrated discrimination index. Thus, modest early changes in serum creatinine can help target biomarker measurement for determining prognosis with urine L-FABP, providing independent and additive prognostic information when combined with clinical predictors.

    Introduction States’ decisions not to expand Medicaid under the Affordable Care Act (ACA) could potentially affect access to care and health status among their low-income residents. Methods The 2010–2012 nationally representative Medical Expenditure Panel Survey data were analyzed in 2015 to compare 9755 low-income adults aged 18–64 years from Medicaid-expanding states with 7455 adults from nonexpanding states. Multivariate logistic regression models were fitted to evaluate the differences in access to care, receipt of preventive services, quality of care, attitudes about health and self-reported health status by Medicaid expansion status. The differences in care utilization and medical expenditures between the two groups were examined using a 2-part modeling approach. Results Compared to their counterparts in Medicaid expansion states, low income adults in the nonexpanding states were more likely to be black and reside in rural areas and were less likely to have a usual source of care (prevalence ratio[PR] 0.86, 95% confidence interval[CI] 0.82–0.91) and recommended preventive services such as dental checkups (PR = 0.86; CI = 0.79–0.94), routine checks (PR = 0.89; CI = 0.83–0.95), flu vaccinations (PR = 0.89; CI = 0.81–0.98), and blood pressure checks (PR = 0.96; CI = 0.94–0.99). They also had less care utilization, fewer prescriptions, and less medical expenditures, but more out-of-pocket expenditures (all p-value <0.05). Conclusions Low-income adults in Medicaid nonexpanding states, who are disproportionately represented by blacks and rural residents, were worse off for multiple health-related outcomes compared to their counterparts in Medicaid expanding states at the baseline of ACA implementation, suggesting that low income adults residing in nonexpanding states may benefit markedly from the expansion of Medicaid.

Whether these types of mutations predict outcome after allogeneic hematopoietic stem-cell transplantation (HSCT) in patients with MDS is not known. Patients and Methods We used massively parallel sequencing to examine tumor samples collected from 87 patients with MDS before HSCT for coding mutations in 40 recurrently mutated MDS genes. Results Mutations were identified in 92% of patients, most frequently in the ASXL1 (29%), TP53 (21%), DNMT3A (18%), and RUNX1 (16%) genes. In univariable analyses, only TP53 mutations were associated with shorter overall (OS; hazard ratio [HR], 3.74; P < .001) and progression-free survival (HR, 3.97; P < .001). After adjustment for clinical variables associated with these end points, mutations in TP53 (HR, 2.30; P = .027), TET2 (HR, 2.40; P = .033), and DNMT3A (HR, 2.08; P = .049) were associated with decreased OS. In multivariable analysis including clinical variables, complex karyotype status, and candidate genes, mutations in TP53 (HR, 4.22; P ≤ .001) and TET2 (HR, 1.68; P = .037) were each independently associated with shorter OS. Nearly one half of patients (46%) carried a mutation in TP53, DNMT3A, or TET2 and accounted for 64% of deaths. Three-year OS in patients without these mutations was 59% (95% CI, 43% to 72%), versus 19% (95% CI, 9% to 33%) in patients with these mutations. Conclusion Mutations in TP53, TET2, or DNMT3A identify patients with MDS with shorter OS after HSCT. PMID:25092778

    Connective tissue growth factor (CTGF/CCN2) has long been associated with human cancers. The role it plays in these neoplasms is diverse and tumour specific. Recurring patterns in clinical outcome, histological desmoplasia and mechanisms of action have been found. When CTGF is overexpressed compared to low-expressing normal tissue or is underexpressed compared to high-expressing normal tissue, the functional outcome favours tumour survival and disease progression. CTGF acts by altering proliferation, drug resistance, angiogenesis, adhesion and migration contributing to metastasis. The pattern of CTGF expression and tumour response helps to clarify the role of this matricellular protein across a multitude of human cancers. PMID:24832082

    This study evaluated the prognostic value of thyroid-related hormones within normal ranges after acute ischemic stroke. This was a retrospective study and we reviewed 1072 ischemic stroke patients consecutively admitted within 72 h after symptom onset. Total triiodothyronine (T3), total thyroxine (T4), free T3, free T4, and thyroid-stimulating hormone (TSH) were assessed to determine their values for predicting functional outcome at the first follow-up clinic visits, which usually occurred 2 to 4 weeks after discharge from the hospital. 722 patients were finally included. On univariate analysis, poor functional outcome was associated with presence of atrial fibrillation as the index event. Furthermore, score of National Institutes of Health Stroke Scale (NIHSS), total T4, free T4, and C-reactive protein at admission were significantly higher in patients with poor functional outcome, whereas free T3 and total T3 were significantly lower. On multiple logistic regression analysis, lower total T3 concentrations remained independently associated with poor functional outcome [odds ratio (OR), 0.10; 95% confidence interval (CI), 0.01–0.84; P = 0.035]. The only other variables independently associated with poor functional outcome were NIHSS scores. In sum, lower total T3 concentrations that were within the normal ranges were independently associated with poor short-term outcomes. PMID:27375741

    Epstein-Barr virus (EBV) positive diffuse large B-cell lymphoma (DLBCL) of the elderly is defined as patients older than 50 years alone. However, recent studies showed young patients with sound immune status could also be affected. In this study, we investigated the clinical features and outcomes of patients with EBV positive DLBCL in the different age groups using different EBER cut-off values. The prevalence of EBV positive DLBCL was 14.0% (35/250) and 10.4% (26/250) for EBER cut-off of 20% and 50%, respectively. With both EBER cut-off values, patients with EBV DLBCL shared many unfavorable prognostic characteristics, regardless of age. EBV positive patients, both in the elderly and young groups, showed significantly worse overall survival and progression-free survival than negative cases. Moreover, no significant differences of outcomes were identified between different age groups with EBV positive DLBCL. In conclusion, EBV positive DLBCL patients, regardless of age, shared similar poor prognostic features and showed worse outcome than negative cases. We suggest that the age criterion of EBV positive DLBCL of the elderly, and possibly the name itself, be modified in future. PMID:26202875

    Malignant pleural mesothelioma (MPM) is the most frequent pleural neoplasm, with asbestos exposure as one of the recognized carcinogen agents, causative in 80% of cases. The prognosis is poor; median survival of untreated cases is 6-9 months, with fewer than 5% of patients surviving 5 years. Sarcomatoid mesothelioma (SM) represents the subtype with the worst outcome and median survival ranging from 3.5 to 8 months. In the last few years, an accurate differentiation between the subtypes of MPM has become a crucial issue, due to differences in chemosensitivity and clinical outcome, and several studies have evaluated different immunohistochemical markers to better define the diagnosis. The different and worse outcome of patients with SM and, in general, nonepithelioid subtypes makes it intriguing to select these cases to better study the biomolecular profile in order to find factors linked to prognosis and/or predictive of therapeutic response. Considering recent studies on miRNA and genetic mapping, further investigation of this rare subtype might represent a field for basic and clinical-translational research providing for more tailored therapies.

    The possibility to regain motor function after stroke depends on the intactness of motor and sensory pathways. In this study, we evaluated afferent sensory pathway information transfer and processing after stroke with the coherence between cortical activity and a position perturbation (position-cortical coherence, PCC). Eleven subacute stroke survivors participated in this study. Subjects performed a motor task with the affected and non-affected arm while continuous wrist position perturbations were applied. Cortical activity was measured using EEG. PCC was calculated between position perturbation and EEG at the contralateral and ipsilateral sensorimotor area. The presence of PCC was quantified as the number of frequencies where PCC is larger than zero across the sensorimotor area. All subjects showed significant contralateral PCC in affected and non-affected wrist tasks. Subjects with poor motor function had a reduced presence of contralateral PCC compared with subjects with good motor function in the affected wrist tasks. Amplitude of significant PCC did not differ between subjects with good and poor motor function. Our results show that poor motor function is associated with reduced sensory pathway information transfer and processing in subacute stroke subjects. Position-cortical coherence may provide additional insight into mechanisms of recovery of motor function after stroke. PMID:25651979

    The histone demethylase KDM1A specifically demethylates lysine residues and its deregulation has been implicated in the initiation and progression of various cancers. However, KDM1A's molecular role and its pathological consequences, and prognostic significance in oral cancer remain less understood. In the present study, we sought to investigate the expression of KDM1A and its downstream role in oral cancer pathogenesis. By comparing mRNA expression profiles, we identified an elevated KDM1A expression in oral tumors when compared to normal oral tissues. In silico pathway prediction identified the association between KDM1A and E2F1 signaling in oral cancer. Pathway scanning, functional annotation analysis and In vitro assays showed the KDM1A's involvement in oral cancer cell proliferation and the cell cycle. Moreover, real time PCR and luciferase assays confirmed KDM1A's role in regulation of E2F1 signaling activity in oral cancer. Elevated KDM1A expression is associated with poor clinical outcome in oral cancer. Our data indicate that deregulated KDM1A expression is positively associated with proliferative phenotype of oral cancer and confers poor clinical outcome. These cumulative data suggest that KDM1A might be a potential diagnostic and therapeutic target for oral cancer. PMID:26225839

    The functional outcomes related to treating patients afflicted with tooth loss are an important hallmark in substantiating prosthodontic intervention. The Oral Rehabilitation Outcomes Network (ORONet) conducted two international workshops to develop a core set of outcome measures, including a functional domain. The process followed the general format used in the Outcome Measures in Rheumatology (OMERACT) workshops to develop consensus for clinical outcome measures in arthritis research, which included: developing a comprehensive list of potential outcomes in the literature; submitting them to a filter for validity, clinical discrimination, and feasibility; and ranking those measures meeting all the filter criteria for relative value. The search was conducted to include functional assessments of speech, swallowing, mastication, nutrition, sensation, and motor function as they relate to dental implant therapies. This literature review surveyed 173 papers that produced some result of these descriptors in the functional domain. Of these, 67 papers reported on functional assessments and further defined objective and subjective outcomes. Many of these results were patient-perceived improvements in function, while others were objective assessments based on established methodologies and instruments. Objective evaluations of masticatory function and speech may meet criteria for validity and discriminability for selected interventions, but are generally not feasible for routine use in clinical care settings. The current recommendation is to employ a well-validated survey instrument that covers mastication and speech, such as the Oral Health Impact Profile (OHIP-14, short form), recognizing that patient perceptions of function may differ from objective ability.

    TRIM66 belongs to the family of tripartite motif (TRIM)-containing proteins. Alterations in TRIM proteins have been implicated in several malignancies. This study was aimed at elucidating the expression and biological function of TRIM66 in osteosarcoma. Here, TRIM66 expression level was higher in osteosarcoma tissues than in normal tissues. High TRIM66 expression was correlated with high rate of local recurrence and lung metastasis, and short survival time. Then, we found that knockdown of TRIM66 in two osteosarcoma cell lines, MG63 and HOS, significantly inhibited cell proliferation and induced G1-phase arrest. Moreover, inhibition of TRIM66 in osteosarcoma cells significantly induced cell apoptosis, while remarkably inhibited cell migration, invasion as well as tumorigenicity in nude mice. Gene set enrichment analysis in Gene Expression Omnibus dataset revealed that apoptosis, epithelial-mesenchymal transition (EMT) and transforming growth factor-β (TGF-β) signaling pathway-related genes were enriched in TRIM66 higher expression patients, which was confirmed by western blot analysis in osteosarcoma cells with TRIM66 silenced. In conclusion, TRIM66 may act as an oncogene through suppressing apoptosis pathway and promoting TGF-β signaling in osteosarcoma carcinogenesis. TRIM66 may be a prognostic factor and potential therapeutic target in osteosarcoma. PMID:26247633

    Background Little is known about the treatment of multidrug-resistant tuberculosis (MDR-TB) in HIV-co-infected adolescents. This study aimed to present the intermediate outcomes of HIV-infected adolescents aged 10–19 years receiving second-line anti-TB treatment in a Médecins Sans Frontières (MSF) project in Mumbai, India. Methods A retrospective review of medical records of 11 adolescents enrolled between July 2007 and January 2013 was undertaken. Patients were initiated on either empirical or individualized second-line ambulatory anti-TB treatment under direct observation. Results The median age was 16 (IQR 14–18) years and 54% were female. Five (46%) adolescents had pulmonary TB (PTB), two (18%) extrapulmonary disease (EPTB) and four (36%) had both. Median CD4 count at the time of MDR-TB diagnosis was 162.7 cells/µl (IQR: 84.8–250.5). By January 2013, eight patients had final and 3 had interim outcomes. Favourable results were seen in four (36.5%) patients: one was cured and three were still on treatment with negative culture results. Seven patients (64%) had poor outcomes: four (36.5%) died and three (27%) defaulted. Three of the patients who died never started on antiretroviral and/or TB treatment and one died 16 days after treatment initiation. Two of the defaulted died soon after default. All patients (100%) on-treatment experienced adverse events (AEs): two required permanent discontinuation of the culprit drug and two were hospitalized due to AEs. No patient required permanent discontinuation of the entire second-line TB or antiretroviral regimens. Conclusions Early mortality and mortality after default were the most common reasons for poor outcomes in this study. Early mortality suggests the need for rapid diagnosis and prompt treatment initiation, and adolescents might benefit from active contact-tracing and immediate referral. Default occurred at different times, suggesting the need for continuous, intensified and individualized psychosocial

    Objective Obese women experience worse reproductive outcomes compared to normal weight women, specifically infertility, pregnancy loss, fetal malformations and developmental delay. The objective of this study was to use a genetic mouse model of obesity in order to recapitulate the human reproductive phenotype and further examine potential mechanisms and therapies. Methods New inbred, polygenic Type 2 diabetic TallyHO mice and age matched control C57BL/6 mice were superovulated to obtain morulae or blastocysts stage embryos which were cultured in human tubal fluid media. Deoxyglucose uptake was performed on insulin-stimulated individual blastocysts. Apoptosis was detected by confocal microscopy using TUNEL assay and Topro-3 nuclear dye. Embryos were scored for %TUNEL positive/total nuclei. AMPK activation, TNFα expression, and adiponectin expression were analyzed by western immunoblot and confocal immunofluorescent microscopy. Lipid accumulation was assayed by Bodipy. Finally all measured parameters were compared between TallyHO mice in morulaes cultured to blastocyst embryos in either human tubal fluid (HTF) media or HTF with 25ug/ml metformin added. Results TallyHo mice developed whole body abnormal insulin tolerance, decreased litter number and increased NEFA. Blastocysts demonstrated increased apoptosis, decreased insulin sensitivity, and decreased activation of AMP activated protein-kinase (AMPK). As a possible cause of the insulin resistance/abnormal P-AMPK, we found that Tumor necrosis Factor (TNFα) expression and lipid accumulation as detected by BODIPY were increased in TallyHO blastocysts and adiponectin was decreased. Culturing TallyHO morulae with the AMPK activator, metformin lead to a reversal of all abnormal findings, including increased p-AMPK, improved insulin-stimulated glucose uptake and normalization of lipid accumulation. Conclusions Women with obesity and insulin resistance experience poor pregnancy outcomes. Previously we have shown in mouse

    Although ovarian cancer is a highly chemosensitive disease, it is only infrequently cured. One of the major reasons lies in the presence of drug-resistant cancer stem-like cells, sufficient to fuel recurrence. We phenotyped cancer stem-like cells by flow cytometry and immunohistochemistry in 55 matched samples before and after taxane/platinum-based neoadjuvant chemotherapy. All used markers of stemness (ALDH1, CD24, CD117, CD133) isolated low frequencies of malignant cells. ALDH1 was the most valuable marker for tracking stemness in vivo. The enrichment of ALDH1 expression after treatment was associated with a poor response to chemotherapy, with platinum resistance and independently prognosticated unfavorable outcome. Our results suggest that increased ALDH1 expression after treatment identifies patients with aggressive tumor phenotypes. PMID:25999351

    An explanation for the higher incidence of cardiovascular disease and heart failure in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) with doxazosin and the Vasodilator Heart Failure Trial (V-HeFT) with prazosin might be decreased expression of heat shock proteins. Heat shock proteins help to protect cells from ischemic injury by decreasing oxidation, suppressing cytokine action, refolding damaged proteins, and decreasing apoptosis. I hypothesize that α-adrenergic blockade decreases heat shock protein levels, thus making the heart and vascular system vulnerable to injury from pathologic processes such as ischemia, hypertension, oxidation or inflammation. Similarly, poor cardiovascular outcomes with calcium-channel blockers might be due to decreased expression of heat shock proteins. PMID:11806806

    Pyruvate kinase M2 (PKM2) contributes to the Warburg effect, a hallmark of cancer. We showed that PKM2 levels were correlated with overall survival (hazard ration = 1.675, 95% confidence interval: 1.389–2.019, P < 0.001) and disease-free survival (hazard ration = 1.573, 95% confidence interval: 1.214–2.038, P < 0.001) in a cohort of 490 patients with HCC. The correlations were further validated in an independent cohort of 148 HCC patients. Multivariate analyses revealed that PKM2 was an independent indicator of poor outcome in HCC. The knockdown of PKM2 in HCC cells inhibited cell proliferation and induced apoptosis in vitro and in vivo. Bim siRNA markedly abolished the PKM2-depletion-induced apoptosis. PKM2 depletion decreased the degradation of Bim. In clinical samples, PKM2 expression was reversely correlated with Bim expression. Combination of PKM2 and Bim levels had the best prognostic significance. We suggest that PKM2 serves as a promising biomarker for poor prognosis of patients with HCC and its knockdown induces HCC apoptosis by stabilizing Bim. PMID:25788265

    Few studies have investigated whether prognostic indicators, which contribute to the transition from acute to chronic low back pain (LBP), are also those which contribute to continuing persistence of chronic LBP. We compared the contribution of physical, psychological and social indicators to predicting disability after one year between consulters with LBP of less than 3 months duration and more than 3 months duration. Data from two large prospective cohort studies of consecutive patients consulting with LBP in general practices were merged, providing complete data for 258 cases with acute/subacute LBP and 668 cases with chronic LBP at 12 months follow-up. There were significant differences between the two LBP groups in baseline characteristics and clinical course of disability, assessed by Roland Morris Disability Questionnaire, during the year of follow-up. Adjusted associations between potential prognostic indicators and disability at 12months were carried out in the two LBP subgroups. The final multivariable regression models showed that being non-employed, having widespread pain, a high level of Chronic Pain Grade, and catastrophising were the strongest prognostic indicators for disability at 12 months in both LBP groups. Fear of pain was significantly associated with disability in chronic LBP. Importantly, beyond baseline disability, the effect size of the other prognostic indicators for poor outcome was rather low. These findings must continue to challenge researchers to identify useful early predictors of outcome in persons with disabling back pain, as screening and targeted treatment approaches are dependent upon prognostic indicators with clinical significance.

    Low T3 syndrome was previously reported to be linked to poor clinical outcomes in critically ill patients. The aim of this study was to evaluate the predictive power of low T3 syndrome for clinical outcomes in patients with community-acquired pneumonia (CAP). Data for 503 patients were analyzed retrospectively, and the primary end point was 30-day mortality. The intensive care unit (ICU) admission rate and 30-day mortality were 8.3% and 6.4% respectively. The prevalence of low T3 syndrome differed significantly between survivors and nonsurvivors (29.1% vs 71.9%, P < 0.001), and low T3 syndrome was associated with a remarkable increased risk of 30-day mortality and ICU admission in patients with severe CAP. Multivariate logistic regression analysis produced an odds ratio of 2.96 (95% CI 1.14–7.76, P = 0.025) for 30-day mortality in CAP patients with low T3 syndrome. Survival analysis revealed that the survival rate among CAP patients with low T3 syndrome was lower than that in the control group (P < 0.01). Adding low T3 syndrome to the PSI and CURB-65 significantly increased the areas under the ROC curves for predicting ICU admission and 30-day mortality. In conclusion, low T3 syndrome is an independent risk factor for 30-day mortality in CAP patients. PMID:26928863

    OBJECTIVE: To determine whether raised plasma glucose concentration independently influences outcome after acute stroke or is a stress response reflecting increased stroke severity. DESIGN: Long-term follow up study of patients admitted to an acute stroke unit. SETTING: Western Infirmary, Glasgow. SUBJECTS: 811 patients with acute stroke confirmed by computed tomography. Analysis was restricted to the 750 non-diabetic patients. MAIN OUTCOME MEASURES: Survival time and placement three months after stroke. RESULTS: 645 patients (86%) had ischaemic stroke and 105 patients (14%) haemorrhagic stroke. Cox's proportional hazards modelling with stratification according to Oxfordshire Community Stroke Project categories identified increased age (relative hazard 1.36 per decade; 95% confidence interval 1.21 to 1.53), haemorrhagic stroke (relative hazard 1.67; 1.22 to 2.28), time to resolution of symptoms > 72 hours (relative hazard 2.15; 1.15 to 4.05), and hyperglycaemia (relative hazard 1.87; 1.43 to 2.45) as predictors of mortality. The effect of glucose concentration on survival was greatest in the first month. CONCLUSIONS: Plasma glucose concentration above 8 mmol/l after acute stroke predicts a poor prognosis after correcting for age, stroke severity, and stroke subtype. Raised plasma glucose concentration is therefore unlikely to be solely a stress response and should arguably be treated actively. A randomised trial is warranted. PMID:9158464

    Objective: To compare the pregnancy outcomes achieved by in vitro fertilization (IVF) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (PORs). Materials and methods: In this randomized controlled trial, 77 PORs undergoing IVF were selected and divided into two groups. First group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphene citrate on day 2of the cycle for 5 day that was followed by150IU/day human menopausal gonadotropin (hMG) on day 5 of the cycle. Second group was the conventional group (n = 35) receiving at least 300 IU/daygonadotropin on day 2 of the cycle. Gonadotropin-releasing hormone (GnRH) antagonist protocol was applied for both groups according to flexible protocol. Number of retrieved oocytes and chemical pregnancy rate were the main outcomes. Results: There was no difference in number ofretrieved oocyte and pregnancy rate (2.79 ± 1.96 vs. 2.20 ± 1.71 and 5.6% vs. 4.1%; p > 0.05) between both groups. The gonadotropin dose used in the minimal stimulation group was lower than conventional group (1046 ± 596 vs. 2806 ± 583). Conclusion: Minimal stimulation protocol with lower gonadotropin used is likely to be considered as a patient- friendly and cost-effective substitute for PORs. PMID:27385972

    Background Dynamic risk estimations may enable targeting primary prevention of overweight and overweight-related adverse cardiometabolic outcome in later life, potentially serving as a valuable addition to universal primary prevention. This approach seems particularly promising in young children, as body mass index (BMI) changes at a young age are highly predictive of these outcomes, and parental lifestyle interventions at a young age are associated with improved long-term outcome. Objective This paper describes the design of our study, which aims to develop digitized tools that can be implemented in the Dutch Child Health Care (CHC) system or by pediatricians for children up to 6 years of age. These tools will enable (1) dynamically predicting the development of overweight, hypertension or prehypertension, low high-density lipoprotein cholesterol (HDL-C) values, and high total cholesterol to HDL-C ratio by early adolescence and (2) identifying children who are likely to have poor cardiometabolic outcome by the age of 5-6 years and by the age of 10 years. Methods Data will be obtained from the Generation R (n=7893) and Prevention and Incidence of Asthma and Mite Allergy (PIAMA; n=3963) cohorts, two Dutch prenatally recruited cohorts. We will select candidate predictors that can be assessed during the first visit and/or during subsequent visits to the CHC center or pediatrician, including sex; parental age, education level, and BMI; smoking exposure; ethnicity; birth weight; gestational age; breastfeeding versus formula feeding; and growth data through the age of 6 years. We will design dynamic prediction models that can be updated with new information obtained during subsequent CHC visits, allowing each measurement to be added to the model. Performance of the model will be assessed in terms of discrimination and calibration. Finally, the model will be validated both internally and externally using the combined cohort data and then converted into a computer

    Objectives Pregnancy carries a high risk for millions of women and varies by urban-rural location in Nigeria, a country with the second highest maternal deaths in the world. Addressing multilevel predictors of poor pregnancy outcomes among antenatal care (ANC) attendees in primary health care (PHC) facilities could reduce the high maternal mortality rate in Nigeria. This study utilised the "Risk Approach" strategy to (1) compare the risks of poor pregnancy outcomes among ANC attendees by urban-rural location; and (2) determine predictors of poor pregnancy outcomes among ANC attendees in urban-rural PHC facilities in Cross River State, Nigeria. Methods A cross-sectional survey was conducted in 2011 among 400 ANC attendees aged 15-49 years recruited through multistage sampling. Data on risk factors of poor pregnancy outcomes were collected using interviewer-administered questionnaires and clinic records. Respondents were categorised into low, medium or high risk of poor pregnancy outcomes, based on their overall risk scores. Predictors of poor pregnancy outcomes were determined by multilevel ordinal logistic regression. Results A greater proportion of the women in the rural areas were below the middle socio-economic quintile (75 vs. 4 %, p < 0.001), had no education (12 vs. 2 %, p < 0.001), and were in the 15-24 age group (58 vs. 35 %, p < 0.001) whereas women in the urban areas were older than 35 years (10 vs. 5 %, p < 0.001). The women attending antenatal care in the urban PHC facilities had a low overall risk of poor pregnancy outcomes than those in the rural facilities (64 vs. 50 %, p = 0.034). Pregnant women in the urban areas had decreased odds of being at high risk of poor pregnancy outcomes versus the combined medium and low risks compared with those in the rural areas (OR 0.55, 95 % CI 0.09-0.65). Conclusions for Practice Pregnant women attending antenatal care in rural PHC facilities are more at risk of poor pregnancy outcomes than those

    We will present the first X-ray Luminosity Function for poor clusters of galaxies. Using a percolation algorithm, White et al. (1996) has compiled a catalog of 600 optically selected groups composed of Zwicky galaxies. This catalog includes MKW and AWM groups (with cD galaxies), many Hickson compact groups, as well as many more loose condensations. We selected a complete,volume-limited subsample of these poor clusters which have at least 4 Zwicky galaxies, b>30deg , a surface density enhancement of ~50, and z <= 0.03. We then cross-correlated this sample with the ROSAT all-sky X-ray survey. About 50% of this sample of 50 clusters was detected with 0.5-2.0 keV X-ray luminosities >4 x 10(41) h75(-2) ergs/sec. These are the X-ray brightest groups in the northern sky. From this sample, we constructed an X-ray Luminosity Function. We find that this poor cluster luminosity function matches well with that derived for Abell clusters by Briel & Henry (1993). It appears that these groups are low mass extensions of rich clusters. We have also derived a mass function for these groups assuming that the X-ray emission is in hydrostatic equilibrium within the clusters. We will compare this mass function with those expected from different cosmological models with different values of Omega . This research was funded by NSF grant AST93-17596 and NASA grant NAGW-3152.

    Our objectives were to evaluate whether low knee confidence at baseline is associated with poor baseline-to-3-year physical function outcome in the Osteoarthritis Initiative (OAI). Knee confidence was assessed using an item from the KOOS instrument. Physical function was assessed using self-report (WOMAC function, SF-12 physical component scale) and performance-based (20 m walk, chair stand test) measures. Poor function outcome was defined as moving into a worse function group or remaining in the 2 worst function groups between baseline and 3 years. Logistic regression was used to evaluate the relationship between baseline knee confidence and poor baseline-to-3-year function outcome, adjusting for potential confounders. The sample included 3975 men and women with or at higher risk to develop knee OA. 37-53% had poor baseline-to-3-year function outcome. For both self-report measures, increasingly worse knee confidence was associated with a greater risk of poor function outcome and trend tests supported a graded response [e.g., for WOMAC, adjusted OR (95% CI) for worsening confidence categories: 1.26 (1.07, 1.49), 1.43 (1.16, 1.77), 2.05 (1.49, 2.82), p for trend <.0001]. Similar associations between confidence and performance-based function outcome were observed but statistical significance did not persist in adjusted analyses. Factors independently associated with poor function outcome for all 4 outcome measures were depressive symptoms, comorbidity, BMI, and joint space narrowing. Worse knee confidence at baseline was independently associated with greater risk of poor function outcome by self-report measures, with evidence of a graded response; the relationship was not significant for the performance measures in the fully adjusted models.

    Importance A major public health concern associated with schizophrenia and psychotic disorders is the long-term disability that involves impaired cognition, lack of social support, and an inability to function independently in the community. A critical goal of early detection and intervention studies in psychosis is therefore to understand the factors leading to this often profound impairment. Objective To develop a predictive model of functional (social and role) outcome in a clinical high-risk sample for psychosis. Design Prospective, naturalistic, longitudinal 3- to 5-year follow-up study. Setting The Recognition and Prevention Program in New York, a research clinic located in the Zucker Hillside Hospital in New York. Participants One hundred one treatment-seeking patients at clinical high risk for psychosis. Ninety-two (91%) were followed up prospectively for a mean (SD) of 3 (1.6) years. Intervention Neurocognitive and clinical assessment. Main Outcomes and Measures The primary outcome variables were social and role functioning at the last follow-up visit. Results Poor social outcome was predicted by reduced processing speed (odds ratio [OR], 1.38; 95% CI, 1.050-1.823; P = .02), impaired social functioning at baseline (OR, 1.85; 95% CI, 1.258-2.732; P = .002), and total disorganized symptoms (OR, 5.06; 95% CI, 1.548-16.527; P = .007). Reduced performance on tests for verbal memory (OR, 1.74; 95% CI, 1.169-2.594; P = .006), role functioning at baseline (OR, 1.34; 95% CI, 1.053-1.711; P = .02), and motor disturbances (OR, 1.77; 95% CI, 1.060-2.969; P = .03) predicted role outcome. The areas under the curve for the social and role prediction models were 0.824 (95% CI, 0.736-0.913; P < .001) and 0.77 (95% CI, 0.68-0.87; P < .001), respectively, demonstrating a high discriminative ability. In addition, poor functional outcomes were not entirely dependent on the development of psychosis, because 40.3% and 45.5% of nonconverters at clinical high risk had poor social

    Advances in task-based functional MRI (fMRI), resting-state fMRI (rs-fMRI), and arterial-spin labeled (ASL) perfusion MRI have occurred at a rapid pace in recent years. These techniques for measuring brain function have great potential to improve the accuracy of prognostication for civilian and military patients with traumatic coma. In addition, fMRI, rs-fMRI, and ASL have provided novel insights into the pathophysiology of traumatic disorders of consciousness, as well as mechanisms of recovery from coma. However, functional neuroimaging techniques have yet to achieve widespread clinical use as prognostic tests for patients with traumatic coma. Rather, a broad spectrum of methodological hurdles currently limits the feasibility of clinical implementation. In this review, we discuss the basic principles of fMRI, rs-fMRI and ASL and their potential applications as prognostic tools for patients with traumatic coma. We also discuss future strategies for overcoming the current barriers to clinical implementation. PMID:23881623

    Introduction Time to achieve target temperature varies substantially for patients who undergo targeted temperature management (TTM) after cardiac arrest. The association between arrival at target temperature and neurologic outcome is poorly understood. We hypothesized that shorter time from initiation of cooling to target temperature (“induction”) will be associated with worse neurologic outcome, reflecting more profound underlying brain injury and impaired thermoregulatory control. Methods This was a multicenter retrospective study analyzing data from the Penn Alliance for Therapeutic Hypothermia (PATH) Registry. We examined the association between time from arrest to return of spontaneous circulation (ROSC) (“downtime”), ROSC to initiation of TTM (“pre-induction”) and “induction” with Cerebral Performance Category (CPC). Results A total of 321 patients were analyzed, of whom 30.8% (99/321) had a good neurologic outcome. Downtime for survivors with good outcome was 11 (IQR 6-27) min vs. 21 (IQR 10-36) min (p=0.002) for those with poor outcome. Pre-induction did not vary between good and poor outcomes (98 (IQR 36-230) min vs. 114 (IQR 34-260) (p=ns)). Induction time in the good outcome cohort was 237 (IQR 142-361) min compared to 180 (IQR 100-276) min (p=0.004). Patients were categorized by induction time (<120 min, 120-300 min, >300 min). Using multivariable logistic regression adjusted for age, initial rhythm, and downtime, induction time > 300 min was associated with good neurologic outcome when compared to those with an induction time < 120 min. Conclusion In this multicenter cohort of post-arrest TTM patients, shorter induction time was associated with poor neurologic outcome. PMID:25447429

    Anaphylatoxin C5a, a potent pro-inflammatory peptide produced in the process of complement activation, was proved to have a vital role in tumor initiation and progession by previous investigations. However whether it could act as a prognostic marker remains unknown. Here we retrospectively enrolled 272 ccRCC patients undergoing nephrectomy in Zhongshan Hospital, Shanghai between 2005 and 2007. C5a level was assessed by immunohistochemistry and its association with clinicopathologic features and prognosis were evaluated. Our results indicated that high tumoral C5a level was associated with poor overall survival (OS) (hazard ratio = 1.753, 95% CI 1.068–2.878, P = 0.026). In addition, tumoral C5a could significantly stratify patients’ prognosis both in advanced stage (TNM III + IV) and intermediate/high risk group (SSIGN score ≥4) (P < 0.001 and = 0.008, respectively). Furthermore, incorporating tumoral C5a with other parameters could improve the predicting accuracy, compared with TNM and SSIGN system (c-index = 0.789, 0.713 and 0.727, respectively). In conclusion, tumoral C5a is an independent adverse prognostic biomarker for clinical outcome of ccRCC patients after nephectomy. PMID:27381421

    NOTCH1 has been found recurrently mutated in a subset of patients with chronic lymphocytic leukemia (CLL). To analyze biological features and clinical impact of NOTCH1 mutations in CLL, we sequenced this gene in 565 patients. NOTCH1 mutations, found in 63 patients (11%), were associated with unmutated IGHV, high expression of CD38 and ZAP-70, trisomy 12, advanced stage and elevated lactate dehydrogenase. Sequential analysis in 200 patients demonstrated acquisition of mutation in one case (0.5%) and disappearance after treatment in two. Binet A and B patients with NOTCH1-mutated had a shorter time to treatment. NOTCH1-mutated patients were more frequently refractory to therapy and showed shorter progression-free and overall survival after complete remission. Overall survival was shorter in NOTCH1-mutated patients, although not independently from IGHV. NOTCH1 mutation increased the risk of transformation to diffuse large B-cell lymphoma independently from IGHV, with this being validated in resampling tests of replicability. In summary, NOTCH1 mutational status, that was rarely acquired during the course of the disease, identify a genetic subgroup with high risk of transformation and poor outcome. This recently identified genetic subgroup of CLL patients deserves prospective studies to define their best management. PMID:23295735

    Objective Using a national database, we asked whether video-assisted thoracoscopic surgery (VATS) lobectomy is beneficial in high-risk pulmonary patients. Background Single-institution series demonstrated benefit of VATS lobectomy over lobectomy via thoracotomy in poor pulmonary function patients [FEV1 (forced expiratory volume in 1 second) or DLCO (diffusion capacity of the lung to carbon monoxide) <60% predicted]. Methods The STS General Thoracic Database was queried for patients having undergone lobectomy by either thoracotomy or VATS between 2000 and 2010. Postoperative pulmonary complications included those defined by the STS database. Results In the STS database, 12,970 patients underwent lobectomy (thoracotomy, n = 8439; VATS, n = 4531) and met inclusion criteria. The overall rate of pulmonary complications was 21.7% (1832/8439) and 17.8% (806/4531) in patients undergoing lobectomy with thoracotomy and VATS, respectively (P < 0.0001). In a multivariable model of pulmonary complications, thoracotomy approach (OR = 1.25, P < 0.001), decreasing FEV1% predicted (OR = 1.01 per unit, P < 0.001) and DLCO% predicted (OR = 1.01 per unit, P < 0.001), and increasing age (1.02 per year, P < 0.001) independently predicted pulmonary complications. When examining pulmonary complications in patients with FEV1 less than 60% predicted, thoracotomy patients have markedly increased pulmonary complications when compared with VATS patients (P = 0.023). No significant difference is noted with FEV1 more than 60% predicted. Conclusions Poor pulmonary function predicts respiratory complications regardless of approach. Respiratory complications increase at a significantly greater rate in lobectomy patients with poor pulmonary function after thoracotomy compared with VATS. Planned surgical approach should be considered while determining whether a high-risk patient is an appropriate resection candidate. PMID:22868367

    The timing and pace of pubertal development has been associated with psychosocial functioning, with pubertal variables represented both as predictors (e.g., earlier puberty linked with poor outcomes) and as sequelae (e.g., early stress linked with earlier puberty). However, the literature has largely not tested mediational models or prospective mechanisms of associations between puberty and psychosocial variables. In a longitudinal study including 454 youth followed over four timepoints (mean ages 10-18), structural equation modeling tested a hypothesized path from childhood maltreatment to cortisol (Time 1) to pubertal stage (Time 2), and psychosocial outcomes (Times 3 and 4). There was not support for the full hypothesized pathway in either gender. However, for boys, maltreatment was associated with attenuated cortisol, and more pubertal change predicted subsequent delinquency. For girls, cortisol predicted more pubertal change which then predicted substance use. This study demonstrates links between HPA axis function, pubertal development, and risky outcomes.

    Vitamin D inadequacy is pandemic among rehabilitation patients in both inpatient and outpatient settings. Male and female patients of all ages and ethnic backgrounds are affected. Vitamin D deficiency causes osteopenia, precipitates and exacerbates osteoporosis, causes the painful bone disease osteomalacia, and worsens proximal muscle strength and postural sway. Vitamin D inadequacy can be prevented by sensible sun exposure and adequate dietary intake with supplementation. Vitamin D status is determined by measurement of serum 25-hydroxyvitamin D. The recommended healthful serum level is between 30 and 60 ng/mL. 25-Hydroxyvitamin D levels of >30 ng/mL are sufficient to suppress parathyroid hormone production and to maximize the efficiency of dietary calcium absorption from the small intestine. This can be accomplished by ingesting 1000 IU of vitamin D(3) per day, or by taking 50,000 IU of vitamin D(2) every 2 weeks. Vitamin D toxicity is observed when 25-hydroxyvitamin D levels exceed 150 ng/mL. Identification and treatment of vitamin D deficiency reduces the risk of vertebral and nonvertebral fractures by improving bone health and musculoskeletal function. Vitamin D deficiency and osteomalacia should be considered in the differential diagnosis of patients with musculoskeletal pain, fibromyalgia, chronic fatigue syndrome, or myositis. There is a need for better education of health professionals and the general public regarding the optimization of vitamin D status in the care of rehabilitation patients. PMID:17507730

    Background and purpose — Recent research on outcomes after total knee arthroplasty (TKA) has raised the question of the ability of traditional outcome measures to distinguish between treatments. We compared functional outcomes in patients undergoing TKA with and without patellar resurfacing, using the knee injury and osteoarthritis outcome score (KOOS) as the primary outcome and 3 traditional outcome measures as secondary outcomes. Patients and methods — 129 knees in 115 patients (mean age 70 (42–82) years; 67 female) were evaluated in this single-center, randomized, double-blind study. Data were recorded preoperatively, at 1 year, and at 3 years, and were assessed using repeated-measures mixed models. Results — The mean subscores for the KOOS after surgery were statistically significantly in favor of patellar resurfacing: sport/recreation, knee-related quality of life, pain, and symptoms. No statistically significant differences between the groups were observed with the Knee Society clinical rating system, with the Oxford knee score, and with visual analog scale (VAS) for patient satisfaction. Interpretation — In the present study, the KOOS—but no other outcome measure used—indicated that patellar resurfacing may be beneficial in TKA. PMID:26540368

    There was fewer paper about the relation between the Hamilton Depression Rating Scale (17 Items, HDRS-17) factors and stroke outcomes. Our aim was to investigate the influence of total score and factors of HDRS-17 on outcome of ischemic stroke at 1 year. A total of 1,953 patients with acute ischemic stroke were enrolled into a multicentered and prospective cohort study. The HDRS-17 was used to assess symptoms at 2 weeks after ischemic stroke. The Modified Ranking Scale (mRS) scores of 3-6 points and 0-2 points were regarded as poor outcome and benign outcome, respectively. At 1 year, 1,753 (89.8 %) patients had mRS score data. After adjusting for the confounders, patients with a total HDRS-17 score of ≥ 8 had a worse outcome at 1 year (OR = 1.62, 95 % CI 1.18-2.23). Symptoms of suicide (OR = 1.89, 95 % CI 1.27-2.83), decreased or loss of interest of work (OR = 1.89, 95 % CI 1.38-2.58), retardation (OR = 1.74, 95 % CI 1.27-2.38), psychic anxiety (OR = 1.72, 95 % CI 1.26-2.34), and agitation (OR = 1.61, 95 % CI 1.08-2.40) increased the risks for poor outcome by >60 %, respectively. Depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia also increased the risk for poor outcome by nearly 50 %, respectively. A total HDRS-17 score of ≥ 8, and suicide, decreased or loss of interest of work, anxiety, agitation, retardation, depressed mood, somatic anxiety, somatic symptoms-gastrointestinal, and early insomnia of the HDRS-17 factors at 2 weeks after ischemic stroke increase the risk for poor outcome at 1 year.

    We evaluated whether African-Americans in the Osteoarthritis Initiative have a greater risk (vs. Caucasians) of poor 4-year function outcome within strata defined by gender, BMI, and waist circumference. Using WOMAC function, 20 meter walk, and chair stand performance, poor outcome was defined as moving into a worse function group or remaining in the 2 worst groups over 4 years. Logistic regression was used to evaluate the relationship between racial group and outcome within each stratum, adjusting for age, education, and income, and then further adjusting for BMI, comorbidity, depressive symptoms, physical activity, knee pain, and OA severity. In 3695 persons with or at higher risk for knee OA, higher BMI and large waist circumference were each associated with poor outcome. Among women with high BMI and among women with large waist circumference, African-Americans were at greater risk for poor outcome by every measure, adjusting for age, education, and income. From fully adjusted models, potential explanatory factors included income, comorbidity, depressive symptoms, pain, and disease severity. Findings were less consistent for men, emerging only for the 20 meter walk or chair stand outcomes, and potentially explained by age and knee pain. Among OAI women with excess body weight, African-Americans are at greater risk than Caucasians for poor 4-year outcome. Modifiable factors that may help to explain these findings in the OAI include comorbidity, depressive symptoms, and knee pain. Targeting such factors, while supporting weight loss, may help to lessen the outcome disparity between African-American and Caucasian women. PMID:22833527

    Many radiobiologic mechanisms may contribute to the clinical radiation resistance of Glioblastoma Multiforme. One of them is considered to be an unusually low intrinsic radiation sensitivity. This is a collaborative study between three laboratories to evaluate the intrinsic radiation sensitivity of 85 cell lines derived from human malignant gliomas as the major cause of the poor clinical results of radiation treatment to these tumors. Fifty-one cell lines were early passage. The distribution by histologic type was: 58 glioblastoma, 17 anaplastic astrocytoma, six oligodendroglioma and four astrocytoma grade 2. The intrinsic radiation sensitivity will be expressed by the surviving fraction at 2 Gy (SF[sub 2]). The SF[sub 2] has been determined for single dose irradiation for cell lines on exponential phase, under aerobic conditions, growing on plastic. The patient age, Karnofski Status, histological grade, survival, dose or irradiation for 50 patients are investigated for correlations with SF[sub 2] of the corresponding newly established cell lines. These data on 85 malignant glioma cell lines show a very broad distribution of SF[sub 2] values for irradiation in vitro. SF[sub 2] reflected the difference in sensitivity between AA (Grade 3) and GBM (Grade) 4. This may suggest that the parameter SF[sub 2] is useful to discriminate between the sensitivity of different grades or types of histology in vitro. However, SF[sub 2] was not a predictor of the clinical outcome on individual basis for malignant gliomas. The in vitro studies will need to be supplemented by physiologic characterization of the tumors in vivo. Such conclusions would limit the predictive value of current radiation sensitivity assays based on in vitro dose-survival measurement for the least high grade malignant gliomas. 34 refs., 4 figs., 2 tabs.

    Three years after its first discovery in Jeddah Saudi Arabia, the novel zoonotic pathogen of humans, the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) continues to be a major threat to global health security.(1) Sporadic community acquired cases of MERS continue to be reported from the Middle East. The recent nosocomial outbreaks in hospitals in Seoul, Korea and at the National Guard Hospital in Riyadh, Saudi Arabia indicate the epidemic potential of MERS-CoV. Currently there are no effective anti-MERS-CoV anti-viral agents or therapeutics and MERS is associated with a high mortality rate (40%) in hospitalised patients. A large proportion of MERS patients who die have a range of pulmonary pathology ranging from pneumonia to adult respiratory distress syndrome with multi-organ failure, compounded by co-morbidities, reflecting a precarious balance of interactions between the host-immune system and MERS-CoV. Whilst we wait for new MERS-CoV specific drugs, therapeutics and vaccines to be developed, there is a need to advance a range of Host-Directed Therapies. A range of HDTs are available, including commonly used drugs with good safety profiles, which could augment host innate and adaptive immune mechanisms to MERS-CoV, modulate excessive inflammation and reduce lung tissue destruction. We discuss the rationale and potential of using Host-Directed Therapies for improving the poor treatment outcomes associated with MERS. Carefully designed randomized controlled trials will be needed to determine whether HDTs could benefit patients with MERS. The recurrent outbreaks of MERS-CoV infections at hospitals in the Middle East present unique opportunities to conduct randomized clinical trials. The time has come for a more coordinated global response to MERS and a multidisciplinary global MERS-CoV response group is required to take forward priority research agendas. PMID:26365771

  1. 25-Hydroxyvitamin D: functional outcomes in infants and young children.

    Vitamin D deficiency occurs in the United States in exclusively breastfed infants who have high levels of skin pigmentation, inadequate vitamin D supplementation, and insufficient sunlight exposure. I review serum 25-hydroxyvitamin D [25(OH)D] concentrations and functional outcomes of vitamin deficiency in young children and breastfed and nonbreastfed infants. These outcomes include the presence or absence of vitamin D deficiency rickets, bone mineral content, and serum parathyroid hormone concentration. Daily vitamin D supplements of 400 IU/L keep serum 25(OH)D concentrations higher than 50 nmol/L and prevent rickets in infants and young children. The available evidence is not sufficient to support the use of bone mineral content or parathyroid hormone concentrations in infants and young children as functional outcomes to define deficient or sufficient levels of 25(OH)D. I therefore propose a research agenda to establish the functional definitions of vitamin D sufficiency or deficiency in infants and young children. PMID:18689395

    There is significant variability in long-term outcomes after traumatic brain injury (TBI), making accurate prognosis difficult. In seeking to enhance understanding of outcomes, this study aimed to investigate whether COMT Val(158)Met allele status was associated with performance on neuropsychological measures of attention and working memory, executive functioning, learning and memory, and speed of information processing in the early rehabilitation phase. The study also aimed to examine whether the COMT polymorphism was associated with longer-term functional outcomes. A total of 223 participants (71.3% male) with moderate-to-severe TBI were recruited as rehabilitation inpatients to participate in a prospective, longitudinal head injury outcome study. The three COMT genotype groups (Val/Val, Val/Met, and Met/Met) were well matched for estimated full-scale IQ, years of education, age at injury, and injury severity. Results showed no significant difference between genotypes on neuropsychological measures (all p>0.05) or functional outcome, as measured by the Glasgow Outcome Scale-Extended (GOS-E), after controlling for age, education, and severity of injury. The presence of frontal lobe pathology was also not associated with cognitive performance. Those with greater injury severity (i.e., longer duration of post-traumatic amnesia) performed more poorly on measures of processing speed and verbal new learning and recall. It was concluded that there was little support for the influence of COMT Val(158)Met on cognitive function, or functional outcome measures, in the acute rehabilitation phase after TBI. PMID:24786534

    Cognitive deficits in major depressive disorder (MDD) patients have been described in numerous studies. However, few reports have aimed to describe cognitive deficits in the remitted state of MDD and the mediational effect of cognitive deficits on occupational outcome. The aim of the current review is to synthesize the literature on the mediating and moderating effects of specific domains of cognition on occupational impairment among people with remitted MDD. In addition, predictors of cognitive deficits found to be vocationally important will be examined. Upon examination of the extant literature, attention, executive function and verbal memory are areas of consistent impairment in remitted MDD patients. Cognitive domains shown to have considerable impact on vocational functioning include deficits in memory, attention, learning and executive function. Factors that adversely affect cognitive function related to occupational accommodation include higher age, late age at onset, residual depressive symptoms, history of melancholic/psychotic depression, and physical/psychiatric comorbidity, whereas higher levels of education showed a protective effect against cognitive deficit. Cognitive deficits are a principal mediator of occupational impairment in remitted MDD patients. Therapeutic interventions specifically targeting cognitive deficits in MDD are needed, even in the remitted state, to improve functional recovery, especially in patients who have a higher risk of cognitive deficit.

    In its recent history, the U.S. Forest Service is among many federal land management agencies struggling with questions concerning why its planning procedures are sometimes inefficient, perform poorly in the eyes of the public, and fail to deliver outputs that advance agency mission. By examining a representative sample of National Environmental Policy Act (NEPA) processes conducted by the agency between 2007 and 2009, we provide new insights into what drives outcomes in these planning processes. We examined team leaders' perceptions of the following outcomes: achievement of agency goals and NEPA mandates, process efficiency, public relations, and team outcomes. The most consistently important predictors of positive outcomes were team harmony and a clearly empowered team leader. Other factors, such as perceptions of the use of best science, a clear and unambiguous purpose and need, team turnover (personnel changes during the process), extra-agency engagement, and intra-agency relations, were also important, but played a less consistent role. The findings suggest the importance of empowering team leaders and team members through enhancing elements of discretion, responsibility, clear role definition, collaborative interdisciplinary deliberation, and perceived self-efficacy. The results also suggest the importance of genuine concern and respect for participating publics and effective inter-agency coordination. PMID:22562009

    People with cystic fibrosis (CF) have been reported to make lung T cell responses that are biased towards T helper (Th) 2 or Th17. We hypothesized that CF-related T cell regulatory defects could be detected by analyzing CD4+ lymphocyte subsets in peripheral blood. Peripheral blood mononuclear cells from 42 CF patients (6 months-53 years old) and 78 healthy controls (2-61 years old) were analyzed for Th1 (IFN-γ+), Th2 (IL-4+), Th17 (IL-17+), Treg (FOXP3+), IL-10+ and TGF-β+ CD4+ cells. We observed higher proportions of Treg, IL-10+ and TGF-β+ CD4+ cells in CF adults (≥ 18 years old), but not children/adolescents, compared with controls. Within the CF group, high TGF-β+% was associated with chronic Pseudomonas aeruginosa lung infection (p < 0.006). We observed no significant differences between control and CF groups in the proportions of Th1, Th2 or Th17 cells, and no association within the CF group of any subset with sex, CFTR genotype, or clinical exacerbation. However, high Th17% was strongly associated with poor lung function (FEV1 % predicted) (p = 0.0008), and this association was strongest when both lung function testing and blood sampling were performed within one week. Our results are consistent with reports of CF as a Th17 disease and suggest that peripheral blood Th17 levels may be a surrogate marker of lung function in CF. PMID:25803862

    Afadin/AF6, an F-actin-binding protein, is ubiquitously expressed in epithelia and has a key role during development, through its regulatory role in cell-cell junction organization. Afadin loss of expression in 15% of breast carcinoma is associated with adverse prognosis and increased risk of metastatic relapse. To determine the role of afadin in breast cancer, we studied the functional consequences of afadin protein extinction using in vitro and in vivo models. Three different breast cancer cell lines representative of the major molecular subtypes were stably repressed for afadin expression (knockdown of afadin (afadin KD)) using RNA interference. Collective and individual migrations as well as Matrigel invasion were markedly increased in afadin KD cells. Heregulin-β1 (HRG-β1)-induced migration and invasion were increased by twofold in afadin KD cells. Conversely, ectopic expression of afadin in the afadin-negative T47D cell line inhibited spontaneous and HRG-β1-induced migrations. RAS/MAPK and SRC kinase pathways were activated in afadin KD cells. Activation levels positively correlated with migration and invasion strength. Use of MEK1/2 (U0126) and SRC kinases (SU6656) inhibitors reduced afadin-dependent migration and invasion. Afadin extinction in the SK-BR-3 cell line markedly accelerated tumor growth development in mouse mammary gland and lung metastasis formation. These results may explain why the loss of afadin expression in tumors correlates with high tumor size and poor metastasis-free survival in patients. PMID:21478912

    Forkhead box F1 (FOXF1), a member of the forkhead transcription factor superfamily, plays critical roles in the progression of certain types of cancers. However, the expression and function of FOXF1 in human hepatocellular carcinoma (HCC) are still unclear. Quantitative real-time reverse transcription polymerase chain reaction, Western blotting, and immunohistochemistry detected the relatively lower expression status of FOXF1 in HCC cases. Soft agar and transwell assays clearly demonstrated that FOXF1-knockdown cells showed significantly increased in vitro cell tumorigenesis and invasion, and FOXF1-overexpressing cells had significantly reduced growth and invasion potential. Our study also examined the role of FOXF1 in HCC cell stemness by sphere formation, aldehyde dehydrogenase (ALDH1) activity, and CD44/133-positive cell analysis. Enforced FOXF1 expression decreased HCC cell stemness, and the downregulation of FOXF1 promoted cancer cell stemness. The in vivo study showed that overexpressed FOXF1 inhibits nude mouse tumorigenicity with downregulation of CD44 and proliferating cell nuclear antigen. More importantly, loss of FOXF1 expression was linked to poor overall survival time by Kaplan–Meier analysis. PMID:27042124

    Background Due to the aging population in low- and middle-income countries, cerebrovascular disease is expected to remain a leading cause of death. Little has been published about stroke in Peru. Aims We conducted a retrospective cohort study of hospitalized stroke patients at a referral center hospital in Lima, Peru to explore factors associated with functional outcome among stroke patients. Methods We identified 579 patients hospitalized for ischemic stroke or intracerebral hemorrhage stroke at the National Institute of Neurologic Sciences in Lima, Peru in 2008 and 2009. A favorable outcome was defined as a modified Rankin score of ≤2 at discharge. Results The mean age was 63.3 years; 75.6% had ischemic stroke; the average length of stay was 17.3 days. At hospital discharge, 231 (39.9%) had a favorable outcome. The overall mortality rate was 5.2%. In multivariate models, the likelihood of having a favorable outcome decreased linearly with increasing age (p=0.02) and increasing NIHSS (p=0.02). Favorable outcome was also associated with male gender (relative risk [RR]=1.2; 95% confidence interval [CI]: 1.0, 1.5) and divorced status (RR=1.3, 95% CI: 1.1, 1.7). Patients on Salud Integral de Salud (public assistance-type insurance, SIS) (RR=0.7, 95% CI: 0.5,1.0) were also less likely to have a favorable outcome. Conclusions Favorable outcome after stroke was independently associated with younger age, lower NIHSS score, male gender, being divorced, and not being on SIS insurance. These findings suggest further study of worse functional outcomes in patients with SIS insurance and confirm the importance of risk adjustment for age, stroke severity (NIHSS) and other socioeconomic factors in outcomes studies. Future studies should preferentially assess outcome at 30-days and 6-months to provide more reliable comparisons and allow additional study of Peruvian end-of-life decision-making and care.

    Background Current literature does not identify the significance of underlying cognitive impairment and delirium on older adults during and 30 days following acute care hospitalization. Objective Describe the incidence, risk factors, and outcomes associated with incident delirium superimposed on dementia. Design 24-month prospective cohort study Setting community hospital Patients 139 older adults (>65 years) with dementia Methods This prospective study followed patients daily during hospitalization and one month post-hospital. Main measures included dementia (Modified Blessed Dementia Rating Score, IQ CODE), daily mental status change, dementia stage/severity (Clinical Dementia Rating, Global Deterioration Scale), delirium (Confusion Assessment Method), and delirium severity (Delirium Rating Scale-Revised-98). All statistical analysis was performed using SAS 9.3 and significance with an alpha level of 0.05. Logistic regression, analysis of covariance or linear regression was performed controlling for age, gender and dementia stage. Results The overall incidence of new delirium was 32% (44/140). Those with delirium had a 25% short term mortality rate, increased length of stay and poorer function at discharge. At one month follow-up, subjects with delirium had greater functional decline. Males were more likely to develop delirium and for every one unit increase in dementia severity (Global Deterioration Scale), subjects were 1.5 times more likely to develop delirium. Conclusions Delirium prolongs hospitalization for persons with dementia. Thus, interventions to increase early detection of delirium have the potential to decrease the severity and duration of delirium and to prevent unnecessary suffering and costs from the complications of delirium and unnecessary readmissions to the hospital.

    OBJECTIVE Summarize functional outcomes after transoral robotic surgery (TORS) ± adjuvant therapy for oropharyngeal cancer (OPC). STUDY DESIGN A systematic review was conducted. The MEDLINE database was searched (MeSH terms: transoral robotic surgery, pharyngeal neoplasms, oropharyngeal neoplasms). METHODS Peer-reviewed human subject papers published through December, 2013 were included. Exclusion criteria were: 1) case report design (n<10), 2) review article, or 3) technical, animal or cadaver studies. Functional outcomes extracted included feeding tube dependence, swallow examination findings, speech ratings, velopharyngeal insufficiency, pneumonia, and oral intake measures. RESULTS Twelve papers comprising 441 patients with OPC treated with TORS ± adjuvant therapy were included. Feeding tube rates were the most commonly reported functional outcome. Excluding prophylactic placement, 18% to 39% of patients required gastrostomy placement, typically during adjuvant therapy. Chronic gastrostomy dependence ranged from 0% to 7% (mean follow-up: 11–26 months), regardless of disease stage. Composite MD Anderson Dysphagia Inventory (MDADI) scores ranged from 65.2 to 78 (89 patients, 3 series, mean follow-up: 12–13 months). Videofluoroscopic swallowing studies were not systematically reported. Incidence of postoperative pneumonia was 0% to 7%. Predictors of swallowing function included baseline function, T-stage, N-stage, tongue base primary tumors, and adjuvant chemoradiation. Rates of transient hypernasality were 4% to 9%. A single study suggested dose-dependent effects of adjuvant therapy (none, radiation alone, chemoradiation) on diet scores at 6- and 12-months. CONCLUSIONS Crude endpoints of functional recovery after TORS ± adjuvant therapy suggest promising swallowing outcomes, depending on the functional measure reported. PMID:24643851

    Pancarpal and partial carpal arthrodesis were performed in 22 carpi (20 cats) using various surgical methods. Short and long-term outcomes were assessed using a retrospective review of the case notes and via owner questionnaires. Carpal arthrodesis was associated with complications that did not affect the functional outcome, and in most cases, did not necessitate major revision surgery. Following arthrodesis, the cats did not jump as high, and showed a reduction in their willingness to jump and climb. Based on our results, carpal arthrodesis is a suitable salvage surgery to treat severe carpal injuries in the cat. PMID:19876518

    Purpose: Poor pulmonary function (PF) is often considered a contraindication to definitive radiation therapy for lung cancer. This study investigated whether baseline PF was associated with radiation-induced lung toxicity (RILT) in patients with non-small cell lung cancer (NSCLC) receiving conformal radiation therapy (CRT). Methods and Materials: NSCLC patients treated with CRT and tested for PF at baseline were eligible. Baseline predicted values of forced expiratory volume in 1 sec (FEV1), forced vital capacity (FVC), and diffusion capacity of lung for carbon monoxide (DLCO) were analyzed. Additional factors included age, gender, smoking status, Karnofsky performance status, coexisting chronic obstructive pulmonary disease (COPD), tumor location, histology, concurrent chemotherapy, radiation dose, and mean lung dose (MLD) were evaluated for RILT. The primary endpoint was symptomatic RILT (SRILT), including grade ≥2 radiation pneumonitis and fibrosis. Results: There was a total of 260 patients, and SRILT occurred in 58 (22.3%) of them. Mean FEV1 values for SRILT and non-SRILT patients were 71.7% and 65.9% (P=.077). Under univariate analysis, risk of SRILT increased with MLD (P=.008), the absence of COPD (P=.047), and FEV1 (P=.077). Age (65 split) and MLD were significantly associated with SRILT in multivariate analysis. The addition of FEV1 and age with the MLD-based model slightly improved the predictability of SRILT (area under curve from 0.63-0.70, P=.088). Conclusions: Poor baseline PF does not increase the risk of SRILT, and combining FEV1, age, and MLD may improve the predictive ability.

    Frequencies of circulating T cells producing IFN-γ, TNF-α, and IL-2, and percentages of T cells proliferating after stimulation with rotavirus (RV), tetanus toxoid, and influenza were evaluated in PBMC derived from healthy adults and children. In addition, the potential anergic state of RV-specific T cells was analyzed by stimulation of PBMC with RV antigen in the presence of three anergy inhibitors (rIL-2, rIL-12, or DGKα-i). The quality and magnitude of RV-T cell responses were significantly lower than those of tetanus toxoid and influenza antigens. RV-CD4 T cell response was enriched in monofunctional IFN-γ{sup +} cells, while influenza-CD4 and tetanus toxoid-CD4 T cell responses were enriched in multifunctional T cells. Moreover, rIL-2 – unlike rIL-12 or DGKα-i – increased the frequencies of RV-CD4 TNF-α{sup +}, CD4 IFN-γ{sup +}, and CD8 IFN-γ{sup +} cells. Thus, circulating RV-T cells seem to have a relatively poor functional profile that may be partially reversed in vitro by the addition of rIL-2. - Highlights: • The quality and magnitude of circulating RV-T cell responses are relatively poor. • Circulating RV-CD4 T cells are enriched in monofunctional IFN-γ+ cells. • Treatment with rIL-2 increased the frequencies of cytokine secreting RV-T cells.

    While the disease course of stress-induced cardiomyopathy (SIC) is usually benign, it can be fatal. The prognostic factors to predict poorer outcome are not well established, however. We analyzed the Acute Physiology And Chronic Health Evaluation (APACHE) II score to assess its value for predicting poor prognosis in patients with SIC. Thirty-seven consecutive patients with SIC were followed prospectively during their hospitalization. Clinical factors, including APACHE II score, coronary angiogram, echocardiography and cardiac enzymes at presentation were analyzed. Of the 37 patients, 27 patients (73%) were women. The mean age was 66.1 ± 15.6 yr, and the most common presentation was chest pain (38%). Initial echocardiographic left ventricular ejection fraction (EF) was 42.5% ± 9.3%, and the wall motion score index (WMSI) was 1.9 ± 0.3. Six patients (16%) expired during the follow-up period of hospitalization. Based on the analysis of characteristics and clinical factors, the only predictable variable in prognosis was APACHE II score. The patients with APACHE II score greater than 20 had tendency to expire than the others (P = 0.001). Based on present study, APACHE II score more than 20, rather than cardiac function, is associated with mortality in patients with SIC. PMID:22219614

    New healthcare demands for quality measures of elective procedures, such as anterior cruciate ligament (ACL) reconstructive surgery, warrant the establishment of high through-put outcomes for high volume clinics. To this end we evaluated the PROMIS and GAITRite as physical function outcome measures to quantify early healing and post-operative complications in 106 patients at pre-op and 3, 10, 20 and 52 weeks post-ACL reconstruction with bone-tendon-bone autograft, and compared the results to the current IKDC validated outcome measure. The results showed that both PROMIS and GAITRite were significantly quicker to administer versus IKDC (p < 0.0001). Additional advantages were that PROMIS and GAITRite detected a significant decrease in physical function at 3 weeks post-op, and a significant improvement at 10 weeks post-op, versus pre-op (p<0.001), which were not detected with IKDC. GAITRite was limited by a low ceiling that could not detect improvement of physical function beyond 20 weeks, while both PROMIS and IKDC detected significant improvement out to 52 weeks postop (p<0.001). Linear regressions demonstrated a significant relationship between IKDC and PROMIS, with a combined correlation value of 0.8954 (p<.001) for all time points. Finally, ROC curve analysis demonstrated that PROMIS is a diagnostic test for poor outcomes. PMID:24532421

    Adolescents with spina bifida (SB), a congenital spinal cord impairment, are at high risk for negative outcomes. Even those with favorable cognitive status often fail to achieve independence, exhibiting poor functional and psychosocial outcomes. The purpose of this study was to examine the relationship between adaptation outcomes (functional status, self-management, and developmental competence) and SB condition-specific, adolescent protective factors, and family protective factors in a sample of adolescents with SB. Individual, interpersonal, and social developmental competence were explored. Sixty-six adolescent/parent pairs were interviewed. Data analysis included descriptive statistics, Cronbach alpha coefficients, and partial correlations controlling for age. All instruments had acceptable reliabilities. Factors associated with outcomes generally fell into two patterns. SB condition-specific variables and adolescent activities (e.g., decision-making, household responsibilities) were related to functional status, self-management, and social competence. In contrast, adolescent beliefs (hope, attitude, and communication efficacy) were predominantly related to individual, interpersonal, and overall developmental competence. PMID:14626030

    The diagnosis of small renal masses (SRMs) continues to increase likely attributable to widespread use of axial cross-sectional imaging. Many of these SRMs present in elderly patients with abnormal baseline renal function. Such patients are at risk for further decline following therapeutic intervention. Renal thermal ablation presents one approach for management of SRMs whereby tumors are treated in situ without need for global renal ischemia. These treatment characteristics contribute to favorable renal function outcomes following kidney tumor ablation particularly in patients with an anatomic or functional solitary renal unit.

Multiobject spectroscopy and wide-field CCD imaging now allow us to measure the GLF of bound group members directly (i.e., without statistical background subtraction) and to compare the group GLF with the GLFs of the field and of rich clusters. We use R-band images in 1.5×1.5 degree2 mosaics to obtain photometry for galaxies in the fields of six nearby (2800poor groups for which we have extensive spectroscopic data, including 328 new galaxy velocities. For the five groups with luminous X-ray halos, the composite group GLF for group members with -23+5loghfunction with M*R=-21.6+/-0.4+5log h and α=-1.3+/-0.1. We also find that (1) the ratio of dwarfs (-17+5logh>=MR>-19+5logh) to giants (MR<=-19+5logh) is significantly larger for the five groups with luminous X-ray halos than for the one marginally X-ray-detected group; (2) the composite GLF for the luminous X-ray groups is consistent in shape with two measures of the composite R-band GLF for rich clusters (Trentham; Driver et al.) and flatter at the faint end than another (α~-1.5 Smith et al.); (3) the composite group GLF rises more steeply at the faint end than the R-band GLF of the Las Campanas Redshift Survey (LCRS; α=-0.7 from Lin et al.), a large volume survey dominated by galaxies in environments more rarefied than luminous X-ray groups; (4) the shape difference between the LCRS field and composite group GLFs results mostly from the population of non-emission line galaxies (EW [O II]<5 Å), whose dwarf-to-giant ratio is larger in the denser group environment than in the field (cf. Ferguson & Sandage; Bromley et al.); and (5) the non-emission line dwarfs are more concentrated about the group center than the non

    Several studies have regarded proximal gastrectomy (PG) as optimal compared to total gastrectomy (TG) for upper stomach cancer. In addition to the traditional outcomes of complication and mortality, change in functional status should be considered as another relevant outcome in aging generations. However, there has been no community-based appraisal of functional outcomes between PG and TG. Using an administrative database, we compared functional outcomes between PG and TG. Among 12,508 patients who survived for ≥15 years and underwent open gastrectomy between 2008 and 2010, we examined patient characteristics, comorbidities, functional status estimated by the Barthel index (BI) at admission and discharge, complications, ICU care, ventilation administration, blood transfusion, operating room time, resumption of oral intake, length of stay and total charges. With reference to distal gastrectomy (DG), we performed multivariate analyses to assess the impacts of PG and TG on complications and BI deterioration. A total of 434 PGs and 4,941 TGs were observed in 148 and 295 hospitals, respectively. Patient characteristics, care process, resumption of oral intake, operating room time, length of stay and total charges were also significantly different among the three gastrectomy types. PG, TG and DG were not associated with complications or functional deterioration. Patient characteristics, preoperative blood transfusion and longer operating room time were significantly associated with more complications and BI deterioration. Since patient case mix and longer operating room time were associated with poor outcomes, physicians should recognize the role of PG and might optimally challenge and complete gastrectomies within the appropriate indications.

    Objective To determine whether a relationship exists between performance-based physical assessments and pre-diabetes/diabetes in an older Chinese population. Methods Our study population comprised 976 subjects (mean ± SD age: 67.6±6.0 years; 44.5% men) from the Hangu area of Tianjin, China. Diabetes was defined by self-reporting of a physician's diagnosis, or a fasting plasma glucose level ≥126 mg/dL; and pre-diabetes was defined as a fasting plasma glucose level ≥100 mg/dL and <126 mg/dL. Results When all other variables were adjusted for, men needing longer to finish a Timed Up and Go Test and a decreased usual walking speed had higher odds of pre-diabetes (P for trend = 0.007 and 0.008, respectively) and diabetes (P for trend = 0.012 and 0.014, respectively). However, women needing longer to finish the test and a decreased usual walking speed had a higher odds of diabetes (P for trend = 0.020 and 0.034, respectively) but not of pre-diabetes. There was no apparent association between grip strength and pre-diabetes/diabetes in both sexes. Conclusions In this study, poor lower extremity function was associated with pre-diabetes/diabetes in older people. PMID:25531769

  4. The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes

    PubMed Central

    2005-01-01

    The duration or magnitude of reinforcement has varied and often appears to have been selected arbitrarily in functional analysis research. Few studies have evaluated the effects of reinforcement magnitude on problem behavior, even though basic findings indicate that this parameter may affect response rates during functional analyses. In the current study, 6 children with autism or developmental disabilities who engaged in severe problem behavior were exposed to three separate functional analyses, each of which varied in reinforcement magnitude. Results of these functional analyses were compared to determine if a particular reinforcement magnitude was associated with the most conclusive outcomes. In most cases, the same conclusion about the functions of problem behavior was drawn regardless of the reinforcement magnitude. PMID:16033163

    The growing burden of chronic kidney disease (CKD), with its associated morbidity and mortality, is recognized as a major public health problem globally and causing substantial load on health care systems. The current framework for the definition and staging of CKD, based on eGFR levels or presence of kidney damage, is useful for clinical classification of patients, but identifies a huge number of people as having CKD which is too many to target for intervention. The ability to identify a subset of patients, at high risk for adverse outcomes, would be useful to inform clinical management. The current staging system applies static definitions of kidney function that fail to capture the dynamic nature of the kidney disease over time. Now-a-days, it is possible to capture multiple measurements of different laboratory test results for an individual including eGFR values. A new possibility for identifying individuals at higher risk of adverse outcomes is being explored through assessment and consideration of the rate of change in kidney function over time, and this approach will be feasible in the current context of digitalization of health record keeping system. On the basis of the existing evidence, this paper summarizes important findings that support the concept of dynamic changes in kidney function over time, and discusses how the magnitude of these changes affect the future adverse outcomes of kidney disease, particularly the End Stage Renal Disease (ESRD), CVD and mortality.

    Objectives Cognitive-behavioral interventions improve outcomes for many pediatric health conditions, but little is known about which mechanisms mediate these outcomes. The goal of this study was to identify whether changes in targeted process variables from baseline to one week post-treatment mediate improvement in outcomes in a randomized controlled trial of a brief cognitive-behavioral intervention for idiopathic childhood abdominal pain. Methods Two-hundred children with persistent functional abdominal pain and their parents were randomly assigned to one of two conditions: a 3-session social learning and cognitive-behavioral treatment (SLCBT) (N=100), or a 3-session educational intervention controlling for time and attention (N=100). Outcomes were assessed at 3, 6 and 12 month follow-ups. The intervention focused on altering parental responses to pain and on increasing adaptive cognitions and coping strategies related to pain in both parents and children. Results Multiple mediation analyses were applied to examine the extent to which the effects of the SLCBT condition on child GI symptom severity and pain as reported by children and their parents were mediated by changes in targeted cognitive process variables and parents’ solicitous responses to their child’s pain symptoms. Reductions in parents’ perceived threat regarding their child’s pain mediated reductions in both parent- and child-reported GI symptom severity and pain. Reductions in children’s catastrophic cognitions mediated reductions in child-reported GI symptom severity but no other outcomes. Reductions in parental solicitousness did not mediate outcomes. Discussion Results suggest that reductions in reports of children’s pain and GI symptoms following a social learning and cognitive-behavioral intervention were mediated at least in part by decreasing maladaptive parent and child cognitions.

    Unexpected medical care spending imposes considerable financial risk on developing country households. Based on managed care models of health insurance in wealthy countries, Colombia’s Régimen Subsidiado is a publicly financed insurance program targeted to the poor, aiming both to provide risk protection and to promote allocative efficiency in the use of medical care. Using a “fuzzy” regression discontinuity design, we find that the program has shielded the poor from some financial risk while increasing the use of traditionally under-utilized preventive services – with measurable health gains.

    We review the literature on two long-term functional outcomes of traumatic brain injury (TBI) important to patients, family members, and rehabilitation treatment teams: work for pay and driving outcomes. Estimates on the percentages working after TBI have ranged widely, and few consistent prognostic indicators of long-term outcomes have been identified. The few large randomized controlled treatment trials of these long-term productive outcomes have been negative, but have identified promising subgroup results that bear further investigation. Salazar et al. (2000) identified patients with loss of consciousness of 1 hour or longer as a subgroup that benefited from intensive in-hospital treatment. Vanderploeg et al. (2008) found that the cognitive treatment arm resulted in improved cognitive performance, and that younger patients benefited more from the cognitive treatment; whereas older patients (31 plus) benefited from a more functional approach to treatment. The research evidence on driving post TBI is sparse - relying upon small studies, and lacking follow-up data. This review included only published research studies of 100 or more subjects, with control groups, and outcomes 6 months or longer after injury. The inclusion of more reliable studies narrowed return to work estimates and provided evidence that type of control group affects findings about return to work after mild TBI (mTBI). Prognostic indicators remain inconsistently measured among these more reliable studies. Heeding the frequent recommendation that research in this area be more stringently conducted, well powered, and use shared measures of critical variables would improve evidence. Adequately powered treatment trials of existing and innovative treatment modalities remain a priority. PMID:25701912

    To review the functional and oncologic outcomes of patients who received supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) in our institution. A total of 208 patients who received SCPL with CHEP or CHP from our institution from 1995 to 2007 were involved. Among them, 190 cases were patients with squamous cell carcinoma of the larynx (T1-T4, N0-N2), 14 cases were patients with recurrent larynx cancer and 4 cases were patients with laryngeal stenosis. Forty-four patients also received unilateral neck dissection, and 41 patients received a bilateral neck dissection. All patients were assessed at functional outcome and complications of their treatment. Also, the oncologic outcomes, such as disease-specific survival, total survival, and local recurrence, were measured for patients with tumor. Decannulation was achieved in nearly all patients, with the average time to decannulation being 20 ± 11.52 days in CHEP patients and 28 ± 8.92 days in CHP patients (P < 0.05). The average nasogastric tubes were removed, days postoperation, was 18 ± 7.39 days in CHEP patients and 25 ± 13.87 days in CHP patients (P < 0.05). The 5-year local recurrence rate was 5.77%, the 5-year disease-specific survival was 82.7%, and the 5-year overall survival was 84.1%. The patients with CHEP had a better recovery than the patients with CHP. SCPL was a well-tolerated procedure with generally good functional outcomes for patients with advanced laryngeal cancer, also for some patients with laryngeal stenosis. PMID:25359194

    Purpose The purpose of this study was to compare medication adherence rates and type 2 diabetes mellitus (T2DM) health outcomes in a sample of underserved patients with suboptimally controlled T2DM (HbA1C>7%) who had received pharmacist-directed medication therapy management (MTM) to those who had not received MTM. Methods A retrospective review of 100 patient records was conducted. For the MTM group, a pharmacist engaged patients in patient-centered services to optimize therapeutic outcomes. Non-MTM patients received usual care. Outcomes were HbA1C, medication adherence, blood pressure, lipids and creatinine. Group comparisons on clinical outcomes were analyzed before and after matching MTM and non-MTM patients on demographic characteristics. Results Before matching, the MTM group had a higher rate of medication adherence than the non-MTM group. Hemoglobin A1C levels were lower in the MTM group compared to the non-MTM group. Similarly, low density lipoprotein (LDL) cholesterol were lower in the MTM group compared to the non-MTM group. After matching, medication adherence rate remained higher in the MTM group than the non-MTM group. Similarly, HbA1C levels remained lower in the MTM group than the non-MTM group. Conclusions There is a paucity of research focused on behavioral interventions for improving health outcomes in underserved communities. Our results advance the existing literature by demonstrating a positive association between pharmacist-directed MTM, medication adherence, and glycemic control in a sample of underserved patients with suboptimally controlled T2DM. A prospective pharmacy intervention and examination of long-term effects of MTM on medication adherence and T2DM health outcomes in this population is warranted. PMID:26009557

  11. Air ions and respiratory function outcomes: a comprehensive review

    PubMed Central

    2013-01-01

    Background From a mechanistic or physical perspective there is no basis to suspect that electric charges on clusters of air molecules (air ions) would have beneficial or deleterious effects on respiratory function. Yet, there is a large lay and scientific literature spanning 80 years that asserts exposure to air ions affects the respiratory system and has other biological effects. Aims This review evaluates the scientific evidence in published human experimental studies regarding the effects of exposure to air ions on respiratory performance and symptoms. Methods We identified 23 studies (published 1933–1993) that met our inclusion criteria. Relevant data pertaining to study population characteristics, study design, experimental methods, statistical techniques, and study results were assessed. Where relevant, random effects meta-analysis models were utilized to quantify similar exposure and outcome groupings. Results The included studies examined the therapeutic benefits of exposure to negative air ions on respiratory outcomes, such as ventilatory function and asthmatic symptoms. Study specific sample sizes ranged between 7 and 23, and studies varied considerably by subject characteristics (e.g., infants with asthma, adults with emphysema), experimental method, outcomes measured (e.g., subjective symptoms, sensitivity, clinical pulmonary function), analytical design, and statistical reporting. Conclusions Despite numerous experimental and analytical differences across studies, the literature does not clearly support a beneficial role in exposure to negative air ions and respiratory function or asthmatic symptom alleviation. Further, collectively, the human experimental studies do not indicate a significant detrimental effect of exposure to positive air ions on respiratory measures. Exposure to negative or positive air ions does not appear to play an appreciable role in respiratory function. PMID:24016271

    Several strains of Sphingobium chlorophenolicum have been isolated from soil that was heavily contaminated with pentachlorophenol (PCP), a toxic pesticide introduced in the 1930s. S. chlorophenolicum appears to have assembled a poorly functioning pathway for degradation of PCP by patching enzymes recruited via two independent horizontal gene transfer events into an existing metabolic pathway. Flux through the pathway is limited by PCP hydroxylase. PCP hydroxylase is a dimeric protein that belongs to the family of flavin-dependent phenol hydroxylases. In the presence of NADPH, PCP hydroxylase converts PCP to tetrachlorobenzoquinone (TCBQ). The kcat for PCP (0.024 s−1) is very low, suggesting that the enzyme is not well evolved for turnover of this substrate. Structure/activity studies reveal that substrate binding and activity are enhanced by a low pKa for the phenolic proton, increased hydrophobicity, and the presence of a substituent ortho to the hydroxyl group of the phenol. PCP hydroxylase exhibits substantial uncoupling; the C4a-hydroxyflavin intermediate, instead of hydroxylating the substrate, can decompose to produce H2O2 in a futile cycle that consumes NADPH. The extent of uncoupling varies from 0 – 100% with different substrates. Uncoupling is increased by the presence of bulky substituents in the 3-, 4-, or 5-position, and lessened by the presence of a chlorine in the ortho position. The effectiveness of PCP hydroxylase is additionally hindered by its promiscuous activity with TCHQ, a downstream metabolite in the degradation pathway. The conversion of TCHQ to TCBQ reverses flux through the pathway. Substantial uncoupling also occurs during the reaction with TCHQ. PMID:22482720

    Background The proximal aspect of the long head of the biceps brachii (LHB) is a frequent source of anterior shoulder pain. Multiple techniques for LHB tenodesis have been described. However, comparative outcomes are lacking. The present study aims to compare functional results, patient reported outcomes, complications, and clinical failures for patients undergoing open versus arthroscopic LHB tenodesis. Methods All patients who underwent open or arthroscopic LHB tenodesis from 2009-2012 at a single institution were identified. Patient demographics, comorbidities, and operative variables of interest, including concomitant procedures, were recorded. Minimum 1-year follow-up was required for inclusion. Outcomes, including patient reported outcomes, physical exam findings, and complications were compared between open and arthroscopic LHB tenodesis patients. Results Overall, 45 patients (25 open, 20 arthroscopic) were available for analysis. In total, there was a single clinical failure in a patient who underwent arthroscopic LHB tenodesis. No other complications or failures were noted. Active shoulder forward elevation was increased in the open tenodesis group as compared to the arthroscopic tenodesis group (177.8 ± 9.3° vs. 171.3 ± 11.7°; p = 0.049). Otherwise, there was no difference in range of motion or strength. For both groups, both the SF-36 and ASES scores improved significantly from preoperative values. Conclusion Both open and arthroscopic LHB tenodesis provide good to excellent outcomes with few complications. Given the recent increased utilization of LHB tenodesis, future studies should use randomization and prospective data collection in order to determine if discrete patient populations are better served by either open or arthroscopic LHB tenodesis techniques PMID:27528841

    Background Violent trauma exposures, including child abuse, are risk factors for PTSD and comorbid mental health disorders. Child abuse experiences of men exacerbate adult male-perpetrated intimate partner violence (IPV). The relationship between child abuse, poor mental health and IPV perpetration is complex but research among the general population is lacking. This study describes the relationship and pathways between history of child abuse exposure and male-perpetrated IPV while exploring the potentially mediating effect of poor mental health. Methods We analysed data from a randomly selected, two-stage clustered, cross-sectional household survey conducted with 416 adult men in Gauteng Province of South Africa. We used multinomial regression modelling to identify associated factors and Structural Equation Modelling (SEM) to test the primary hypothesis that poor mental health (defined as abusing alcohol or having PTSD or depressive symptoms) mediates the relationship between child abuse and IPV perpetration. Results Eighty eight percent of men were physically abused, 55% were neglected, 63% were emotionally abused and 20% were sexually abused at least once in their childhood. Twenty four percent of men had PTSD symptoms, 24% had depressive symptoms and 36% binge drank. Fifty six percent of men physically abused and 31% sexually abused partners at least once in their lifetime. Twenty two percent of men had one episode and 40% had repeat episodes of IPV perpetration. PTSD symptomatology risk increased with severity of child trauma and other trauma. PTSD severity increased the risk for binge drinking. Child trauma, other trauma and PTSD symptomatology increased the severity of depressive symptoms. PTSD symptomatology was comorbid with alcohol abuse and depressive symptoms. Child trauma, having worked in the year before the survey, other trauma and PTSD increased the risk of repeat episodes of IPV perpetration. Highly equitable gender attitudes were protective

    Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which disabling muscle weakness may affect health-related quality of life (HRQoL). The aim of this study was to investigate which common motor-functional deficits and corresponding severity are most determinant of poor HRQoL in these patients. In 41 patients, the dichotomized first item of the Italian Myasthenia Gravis Questionnaire (IMGQ), categorizing patients who report "good" and "poor" HRQoL, was chosen as dependent-outcome variable. All items composing the myasthenia gravis-specific scale (MG-ADL), i.e. talking, chewing, swallowing, breathing, impairment of ability to brush teeth or comb hair, impairment of ability to rise from chair, double vision, and eyelid droop were acquired as independent variables and dichotomized. Stepwise backward LR multivariable logistic regression analysis was performed. In addition, the main characteristics of patients were compared. MG-ADL items "chewing" ≥1, i.e. "fatigue chewing solid food", and "breathing" ≥2, i.e. "shortness of breath at rest" proved to be significant determinants. Higher dose of corticosteroid therapy was significantly (p = 0.027; r s  = -0.35), correlated with poor HRQoL. At diagnosis, a decremental response to repetitive nerve stimulation (RNS) from the abductor pollicis brevis was significantly more frequent in patients with poor HRQoL. In conclusion, impaired "chewing" and "breathing" functions indicate the need for careful planning of rehabilitation, re-education and patient management. Moreover, decremental response to RNS at diagnosis may identify patients at risk for poor HRQoL. PMID:27038315

    Although research suggests that stress exposure and family functioning are associated with internalizing problems in adolescents and caregivers, surprisingly few studies have investigated the mechanisms that underlie this association. To determine whether family functioning buffers the development of internalizing problems in stress-exposed families, we assessed the relation between stress exposure, family functioning, and internalizing symptoms among a large sample of inner-city male youth and their caregivers living in poverty across five waves of data collection. We hypothesized that stress exposure and family functioning would predict development of subsequent youth and caregiver internalizing problems and that family functioning would moderate this relation, with higher functioning families demonstrating greater resiliency to stress exposure. We used a longitudinal, prospective design to evaluate whether family functioning (assessed at waves one through four) activated or buffered the effects of stress exposure (assessed at wave one) on subsequent internalizing symptoms (assessed at waves four and five). Stress from Developmental Transitions and family functioning were significant predictors of depressive symptoms and anxiety in youth; however, family functioning did not moderate the relation. Family functioning mediated the relation between stress from Daily Hassles and internalizing outcomes suggesting that poor parenting practices, low structure, and low emotional cohesion activate depression and anxiety in youth exposed to chronic and frequent everyday stressors. Surprisingly, only family functioning predicted depressive symptoms in caregivers. Results validate the use of a comprehensive, multi-informant assessment of stress when investigating internalizing outcomes in youth and support using family-based interventions in the treatment and prevention of internalizing.

    Purpose Previous studies have shown the role of Sal-like protein 4 (SALL4) as a biomarker in hepatocellular carcinoma (HCC), and some studies have shown the relationship between SALL4 and prognosis. Given the debates in study groups differences in terms of etiologic causes between Western and Asian HCC and detection methods, we attempted to verify the features of SALL4 immunoreactivity and its clinical correlation in Korean HCC patients. Methods Immunohistochemical staining of SALL4 of tissue microarrays (TMAs) consisting of 213 surgically resected HCC patients' tissue were scored in a semiquantitative scoring system with immunoreactive score and the results analyzed with clinical outcome, in addition to general demographics and clinical characteristics. Results SALL4 immunoreactivity was expressed in 50 cases. Relevance between SALL4 and α-FP correlated significantly (P = 0.002). Also, the SALL4-positive patients had considerably higher tumor grade (P < 0.001). The survival analysis showed negative correlation with SALL4 immunoreactivity in all HCC patient groups, but SALL4 immunoreactivity in T3 and T4 HCC correlated with poor prognosis. Conclusion Here, we found that positive immunostaining of SALL4 is correlated with poor patient survival outcome in large and undifferentiated Korean HCC. SALL4 expression showed close relationship with clinical outcomes of HCCs in Korean patients. PMID:27433461

    OBJECT Patients presenting with large-territory ischemic strokes may develop intractable cerebral edema that puts them at risk of death unless intervention is performed. The purpose of this study was to identify predictors of outcome for decompressive hemicraniectomy (DH) in ischemic stroke. METHODS The authors conducted a retrospective electronic medical record review of 1624 patients from 2006 to 2014. Subjects were screened for DH secondary to ischemic stroke involving the middle cerebral artery, internal carotid artery, or both. Ninety-five individuals were identified. Univariate and multivariate analyses were performed for an array of clinical variables in relationship to functional outcome according to the modified Rankin Scale (mRS). Clinical outcome was assessed at 90 days and at the latest follow-up (mean duration 16.5 months). RESULTS The mean mRS score at 90 days and at the latest follow-up post-DH was 4. Good functional outcome was observed in 40% of patients at 90 days and in 48% of patient at the latest follow-up. The mortality rate at 90 days was 18% and at the last follow-up 20%. Univariate analysis identified a greater likelihood of poor functional outcome (mRS scores of 4-6) in patients with a history of stroke (OR 6.54 [95% CI1.39-30.66]; p = 0.017), peak midline shift (MLS) > 10 mm (OR 3.35 [95% CI 1.33-8.47]; p = 0.011), or a history of myocardial infarction (OR 8.95 [95% CI1.10-72.76]; p = 0.04). Multivariate analysis demonstrated elevated odds of poor functional outcome associated with a history of stroke (OR 9.14 [95% CI 1.78-47.05]; p = 0.008), MLS > 10 mm (OR 5.15 [95% CI 1.58-16.79; p = 0.007), a history of diabetes (OR 5.63 [95% CI 1.52-20.88]; p = 0.01), delayed time from onset of stroke to DH (OR 1.32 [95% CI 1.02-1.72]; p = 0.037), and evidence of pupillary dilation prior to DH (OR 4.19 [95% CI 1.06-16.51]; p = 0.04).

    Surgical reconstruction of an injured anterior cruciate ligament (ACL) leads to full recovery of function and sports activity in a high percentage of cases. The aim of the present study was to analyze variables related to the patient, the surgical technique and the post-surgical rehabilitation methods, seeking to identify predictors of outcome and recovery time after ACL reconstruction. One hundred and four patients (81 M, 23 F) undergoing a step-based rehabilitation protocol after ACL reconstruction were evaluated. 43.2% of them had an isolated ACL lesion, whereas 56.8% had one or more concurrent injuries. Data relating to personal characteristics, surgery and post-operative management were collected and analyzed for correlation. Clinical outcome was evaluated with IKDC subjective score and the Tegner score, and the time to reach full recovery was noted as well. Young patients with a higher pre-injury Tegner activity level or who practice sport at professional level, no concurrent capsular lesions and no postoperative knee bracing had better clinical results and took shorter time to recover. Also, a higher percentage of on-the-field rehabilitation sessions, and absence of significant muscle strength deficits at the first knee isokinetic test emerged as rehabilitation-related factors leading to a better post-surgical outcome. Personal, surgical and rehabilitation factors should be considered in order to optimize patient management and maximize the expected results. Further studies are needed to find the strongest factors in different patients. Level of evidence Level IV, retrospective study. PMID:26904523

    Background Approximately 12% of operations for traumatic neuropathy are for patients with segmental nerve loss and less than 50% of these injuries obtain meaningful functional recovery. Polyethylene glycol (PEG) therapy has been shown to improve functional outcomes after nerve severance and we hypothesized this therapy could also benefit nerve autografting. Methods A segmental rat sciatic nerve injury model was used, whereby a 0.5 cm defect was repaired with an autograft using microsurgery. Experimental animals were treated with solutions containing methylene blue (MB) and PEG; control animals did not receive PEG. Compound Actions Potentials (CAPs) were recorded before nerve transection, after solution therapy, and at 72 hours postoperatively. The animals underwent behavioral testing at 24 and 72 hours postoperatively. After sacrifice, nerves were fixed, sectioned, and immunostained to allow for quantitative morphometric analysis. Results The introduction of hydrophilic polymers greatly improved morphological and functional recovery of rat sciatic axons at 1–3 days following nerve autografting. PEG therapy restored CAPs in all animals and CAPs were still present 72 hours postoperatively. No CAPS were detectable in control animals. Footfall asymmetry scores and sciatic functional index scores were significantly improved for PEG therapy group at all time points (p <0.05 and p<0.001; p <0.001 and p <0.01). Sensory and motor axon counts were increased distally in nerves treated with PEG compared to control (p = 0.0189 and p = 0.0032). Conclusions PEG therapy improves early physiologic function, behavioral outcomes, and distal axonal density after nerve autografting. PMID:22521220

    In this study, we investigated the role of inositol polyphosphate-4-phosphatase, type-II (INPP4B) in acute myeloid leukemia (AML). We observed that AML patients with high levels of INPP4B (INPP4B(high)) had poor response to induction therapy, shorter event-free survival and shorter overall survival. Multivariate analyses demonstrated that INPP4B(high) was an independent predictor of poor prognosis, significantly improving current predictive models, where it outperformed conventional biomarkers including FLT3-ITD and NPM1. Furthermore, INPP4B(high) effectively segregated relative risk in AML patients with normal cytogenetics. The role of INPP4B on the biology of leukemic cells was assessed in vitro. Overexpression of INPP4B in AML cell lines enhanced colony formation potential, recapitulated the chemotherapy resistance observed in AML patients and promoted proliferation in a phosphatase-dependent, and Akt-independent manner. These findings reveal that INPP4B(high) has an unexpected role consistent with oncogenesis in AML, in contrast to its previously reported tumor-suppressive role in epithelial cancers. Overall, we propose that INPP4B is a novel prognostic biomarker in AML that has potential to be translated into clinical practice both as a disease marker and therapeutic target. PMID:25736236

    Infliximab is an anti-tumor necrosis factor (TNF)-α antibody drug that suppresses TNF-α and its associated inflammatory responses. Although infliximab therapy generally results in a 75% or greater improvement in the Psoriasis Area and Severity Index from baseline in psoriasis patients, there is the heterogeneity of therapeutic efficacy in psoriasis patients among patients of a similar PASI baseline score. However, there are few published reports about the predictors of the clinical response among psoriasis patients who undergo biologic therapies. We thus evaluated the possible existence of biologic markers that would indicate poor prognosis of infliximab using skin biopsy specimens. This was because we assumed that the inhibitors for upregulated chemokine/chemokine receptors in non-responders may have the ability to reduce the occurrence of psoriatic eruptions. PCR array analyses identified that the levels of various chemokines and chemokine receptors were increased in non-responders in comparison to responders. Immunohistochemical analyses revealed that upregulation of the CCR9 protein levels was not associated with the pretherapeutic PASI score, but with poor response to infliximab. Our results indicated that the expression levels of CCR9 in lesional skin may be a useful biologic marker of the clinical efficacy of infliximab therapy in psoriasis patients. PMID:26507968

    Patients with schizophrenia have impaired everyday living and social outcomes. Performance-based measures, including neuropsychological (NP) performance and functional capacity (FC) measures have demonstrated usefulness in predicting these outcomes. We examined the correlation of demographic factors (race, age, and education) and FC measures, and the relative ability of NP performance, FC, and demographic factors to predict real-world outcomes in social, vocational, and residential domains in 194 outpatients with schizophrenia. Age, education, sex, and racial status were significantly, but modestly, associated with performance-based measures of everyday functioning, while, in addition, age and education had a similar modest relationship with social competence. Age, but none of the other demographic variables, contributed to the prediction of all three domains of everyday functioning. Functional capacity variables predicted everyday outcomes even when demographic variables were entered into a predictive equation first. These data suggest a similar and modest but detectable effect of demographic factors on performance-based measures of functional capacity as seen with NP performance in schizophrenia populations. Older age contributed to poorer everyday functioning even after consideration of functional capacity, which seems similar to findings in healthy populations without clinically notable cognitive decline.

    Reduced nuclear p27 expression is associated with a poor outcome in various cancers, including non-small cell lung cancer (NSCLC). Cytoplasmic p27 expression was shown to be associated with an unfavorable response to chemotherapy and poor outcomes in some carcinomas, but it has not been well studied in NSCLC. Herein, p27 expression in 219 tumors surgically resected from NSCLC patients was evaluated by immunohistochemistry (IHC). The most common of p27 immunostaining in lung tumors was observed in the cytoplasm (N-/C+, 32 %), followed by negative (N-/C-, 29 %), nucleus (N+/C-, 24 %), and nucleus plus cytoplasm (N+/C+, 15 %). Kaplan-Meier and Cox regression models showed that p27 N-/C+ tumors exhibited the worst overall survival (OS) and relapse-free survival (RFS) among the four categories of tumors. Among 135 of 219 patients who received cisplatin-based chemotherapy, p27 N-/C+ tumors most commonly showed an unfavorable response to cisplatin-based chemotherapy, followed by p27 N-/C- tumors when p27 N+/C- tumors were used as a reference. IHC analysis for phosphorylated extracellular signal-regulated kinase (p-ERK) and Bcl-2 expression in the lung tumors was performed to test whether ERK activation could enhance p27 nuclear export and the expression of Bcl-2 to test whether ERK activation could enhance p27 nuclear export and Bcl-2 expression. The data showed that p-ERK expression was positively correlated with cytoplasmic p27 (N-/C+) and Bcl-2 expression in the lung tumors. Patients with high Bcl-2-expressing tumors treated with cisplatin-based chemotherapy showed unfavorable predictive values in a subset of this study population. Therefore, we suggest that cytoplasmic p27 (N-/C+) via ERK-activated Bcl-2 expression may predict an unfavorable response to cisplatin-based chemotherapy and poor outcomes in NSCLC. PMID:26482622

    Purpose For this study, the impact of basal FSH levels on ART outcomes was assessed. Methods From June 2003 to May 2006, 191 ART cycles were performed in our hospital. All cases were treated with GnRH-a long protocol. The patients were classified according to their basal FSH level as follows: group A: FSH < 10 IU/l, group B: 10 ≦ FSH < 15 IU/l, and group C: 15 IU/l ≦ FSH. ART outcomes were compared among the three groups. Results The number of retrieved oocytes in group A was significantly higher than in group B, but fertilized oocytes and the pregnancy rates were comparable. The pregnancy rate in group C was not significantly lower than those found in either group A or B, but the trend was lower. Conclusion Oocytes retrieved from the patients who showed basal FSH levels below 15 IU/l were found to possess significant pregnancy potential. PMID:18228128

    Background. Injuries of the midfoot are often missed and therefore underestimated. Early diagnosis and treatment are crucial for the final outcome. The primary aim of this study was to assess the pattern and results of early operative management of mid-foot injuries after a midterm follow up. Material and methods. This study was conducted on 25 patients (19 Males, 6 Females ) with mean age of 34.6 years (range 18-60 years) with mid-foot fracture dislocations who were admitted consecutively at our centre from May 2008 through November 2010. 25 patients fulfilling our inclusion criteria with mid-foot fracture dislocations were included in this study. Mechanism of injury, its pattern and results of operative management of midfoot injuries were assessed after acute management of these fractures on urgent basis. Evaluation of results was done by AOFAS Score. Results. Most common mode of injury was indirect trauma due to fall (n=12) followed by road traffic accident (n=9). Males (n=19) outnumbered females (n=6). The pattern of injuries requiring operative treatment as per our criteria were Lisfranc fracture dislocations (n=22) and navicular fractures (n=3). The mean follow up was 3.2 years and mean AOFAS score at 3.2 years was 78.36, with most patients losing points to pain and decreased recreational function. Conclusion. The Lisfranc fracture dislocations are the most common injuries around midfoot requiring operative treatment, and we believe that operative treatment considerably improves functional outcome in these injuries.

    Background: During normal pregnancy, changes in thyroid function are well documented; however, information regarding thyroid function in preeclampsia is scanty. Aim: The present study was planned to study thyroid hormones in mild and severe preeclamptic women and normotensive women and correlate them with outcome of pregnancy. Subject and Methods: Thyroid hormones were analyzed in mild (n = 50) and severe (n = 50) cases of preeclamptic women and normotensive women (n = 100). Results: Thyroid-stimulating hormone (TSH) and TT4 levels were higher in mild preeclampsia as compared with severe preeclampsia (P < 0.001 and P < 0.01, respectively). TT3 levels were lower in preeclampsia (more so in severe preeclamptics as compared with normotensive pregnant and non-pregnant women). Preeclamptic with raised TSH levels had significantly higher mean arterial blood pressure and low birth weight (BW). A negative correlation was observed between BW and TSH levels (r = 0.296, P < 0.001) and BW and TT4 levels. A positive correlation was observed between BW and TT3 levels. Conclusion: These findings indicate that there is a state of biochemical hypothyroidism that correlates with severity of preeclampsia and influences obstetric outcome in these women. Identification of thyroid hormone in pregnancy might be of help in predicting occurrence of preeclampsia. PMID:23634328

    Triple negative breast cancer is known for its visceral metastasis. We have found that CXCR4 is overexpressed in triple negative breast cancer and is associated with visceral metastasis. We further investigated whether CXCR4 is a prognostic factor affecting survival following visceral metastasis in breast cancer patients. Our results indicate that increased CXCR4 expression among breast cancer patients with visceral metastasis was positively correlated with poor overall survival (P<0.001). Silencing of CXCR4 was associated with a decrease in the tumorigenic properties of MDA-MB-231 breast cancer cells, caused reversion of EMT and suppression of MMP-9, increased apoptosis, and caused a reduced incidence of tumor lung metastasis in mice. These results are indicative of CXCR4 having a predictive role in patients with visceral metastasis and indicate that shRNA knock down of CXCR4 might be a novel therapeutic strategy to prevent breast cancer metastasis when CXCR4 is overexpressed.

    Existing preclinical and clinical data suggest that the presence of a systemic inflammatory response plays a critical role in the progression of several solid tumors. The derived neutrophil-to-lymphocyte ratio (dNLR) represents an easily determinable marker of systemic inflammation and has been proposed as a potential prognostic marker. The present study was performed to validate and further clarify the prognostic relevance of an elevated pre-treatment dNLR in a large cohort of European breast cancer patients. Data from 762 consecutive female breast cancer patients treated from 1999 to 2004 were evaluated. Disease-free survival (DFS) and overall survival (OS) were assessed using the Kaplan-Meier method. To evaluate the prognostic relevance, univariate and multivariate Cox regression models were performed for each endpoint. Applying receiver operating characteristics (ROC) analysis, the optimal cutoff level for the dNLR was 3. In univariate analysis, a dNLR ≥3 was associated with poor DFS (hazard ratio (HR) 1.87, 95 % confidence interval (CI) 1.28-2.73, p = 0.001) and OS (HR 1.67, 95 % CI 1.07-2.63, p = 0.025). Multivariate analysis revealed a significant association between the elevated dNLR and poor DFS (hazard ratio (HR) 1.70, 95 % CI 1.09-2.65, p = 0.018) but did not show a significant association between the dNLR and OS (HR 1.54, 95 % CI 0.91-2.59, p = 0.106). The present study shows that the pre-treatment dNLR is an independent prognostic factor that could be useful for future individual risk assessment in breast cancer patients. PMID:26219894

    Background Breast cancer patients who are resistant to neoadjuvant chemotherapy (NeoCT) have a poor prognosis. There is a pressing need to develop in vivo models of chemo resistant tumors to test novel therapeutics. We hypothesized that patient-derived breast cancer xenografts (BCXs) from chemo- naïve and chemotherapy-exposed tumors can provide high fidelity in vivo models for chemoresistant breast cancers. Methods Patient tumors and BCXs were characterized with short tandem repeat DNA fingerprinting, reverse phase protein arrays, molecular inversion probe arrays, and next generation sequencing. Results Forty-eight breast cancers (24 post-chemotherapy, 24 chemo-naïve) were implanted and 13 BCXs were established (27%). BCX engraftment was higher in TNBC compared to hormone-receptor positive cancer (53.8% vs. 15.6%, p = 0.02), in tumors from patients who received NeoCT (41.7% vs. 8.3%, p = 0.02), and in patients who had progressive disease on NeoCT (85.7% vs. 29.4%, p = 0.02). Twelve patients developed metastases after surgery; in five, BCXs developed before distant relapse. Patients whose tumors developed BCXs had a lower recurrence-free survival (p = 0.015) and overall survival (p<0.001). Genomic losses and gains could be detected in the BCX, and three models demonstrated a transformation to induce mouse tumors. However, overall, somatic mutation profiles including potential drivers were maintained upon implantation and serial passaging. One BCX model was cultured in vitro and re-implanted, maintaining its genomic profile. Conclusions BCXs can be established from clinically aggressive breast cancers, especially in TNBC patients with poor response to NeoCT. Future studies will determine the potential of in vivo models for identification of genotype-phenotype correlations and individualization of treatment. PMID:26325287

    Pancreatic cancer has a 5-year survival rate of less than 4%. Despite advances in diagnostic technology, pancreatic cancer continues to be diagnosed at a late and incurable stage. Accurate biomarkers for early diagnosis and to predict treatment response are urgently needed. Since alteration of glucose metabolism is one of the hallmarks of cancer cells, we proposed that pyruvate kinase type M2 (M2PK) and lactate dehydrogenase A (LDHA) enzymes could represent novel diagnostic markers and potential therapeutic targets in pancreatic cancer. In 266 tissue sections from normal pancreas, pancreatic cystic neoplasms, pancreatic intraepithelial neoplasia (PanIN) and cancer, we evaluated the expression of PKM2, LDHA, Ki-67 and CD8+ by immunohistochemistry and correlated these markers with clinicopathological characteristics and patient survival. PKM2 and LDHA expression was also assessed by Western blot in 10 human pancreatic cancer cell lines. PKM2 expression increased progressively from cyst through PanIN to cancer, whereas LDHA was overexpressed throughout the carcinogenic process. All but one cell line showed high expression of both proteins. Patients with strong PKM2 and LDHA expression had significantly worse survival than those with weak PKM2 and/or LDHA expression (7.0 months vs. 27.9 months, respectively, p = 0.003, log rank test). The expression of both PKM2 and LDHA correlated directly with Ki-67 expression, and inversely with intratumoral CD8+ cell count. PKM2 was significantly overexpressed in poorly differentiated tumours and both PKM2 and LDHA were overexpressed in larger tumours. Multivariable analysis showed that combined expression of PKM2 and LDHA was an independent poor prognostic marker for survival. In conclusion, our results demonstrate a high expression pattern of two major glycolytic enzymes during pancreatic carcinogenesis, with increased expression in aggressive tumours and a significant adverse effect on survival.

    Background: Although fast food consumption has been linked to adverse health outcomes, the relative contribution of fast food itself compared with the rest of the diet to these associations remains unclear. Objective: Our objective was to compare the independent associations with overweight/obesity or dietary outcomes for fast food consumption compared with dietary pattern for the remainder of intake. Design: This cross-sectional analysis studied 4466 US children aged 2–18 y from NHANES 2007–2010. Cluster analysis identified 2 dietary patterns for the non–fast food remainder of intake: Western (50.3%) and Prudent. Multivariable-adjusted linear and logistic regression models examined the association between fast food consumption and dietary pattern for the remainder of intake and estimated their independent associations with overweight/obesity and dietary outcomes. Results: Half of US children consumed fast food: 39.5% low-consumers (≤30% of energy from fast food) and 10.5% high-consumers (>30% of energy). Consuming a Western dietary pattern for the remainder of intake was more likely among fast food low-consumers (OR: 1.51; 95% CI: 1.24, 1.85) and high-consumers (OR: 2.21; 95% CI: 1.60, 3.05) than among nonconsumers. The remainder of diet was independently associated with overweight/obesity (β: 5.9; 95% CI: 1.3, 10.5), whereas fast food consumption was not, and the remainder of diet had stronger associations with poor total intake than did fast food consumption. Conclusions: Outside the fast food restaurant, fast food consumers ate Western diets, which might have stronger associations with overweight/obesity and poor dietary outcomes than fast food consumption itself. Our findings support the need for prospective studies and randomized trials to confirm these hypotheses. PMID:24153348

    2013-01-01

    Background High risk, unfavorable classical Hodgkin lymphoma (cHL) includes those patients with primary refractory or early relapse, and progressive disease. To improve the availability of biomarkers for this group of patients, we investigated both tumor biopsies and peripheral blood leukocytes (PBL) of untreated (chemo-naïve, CN) Nodular Sclerosis Classic Hodgkin Lymphoma (NS-cHL) patients for consistent biomarkers that can predict the outcome prior to frontline treatment. Methods and materials Bioinformatics data mining was used to generate 151 candidate biomarkers, which were screened against a library of 10 HL cell lines. Expression of FGF2 and SDC1 by CD30+ cells from HL patient samples representing good and poor outcomes were analyzed by qRT-PCR, immunohistochemical (IHC), and immunofluorescence analyses. Results To identify predictive HL-specific biomarkers, potential marker genes selected using bioinformatics approaches were screened against HL cell lines and HL patient samples. Fibroblast Growth Factor-2 (FGF2) and Syndecan-1 (SDC1) were overexpressed in all HL cell lines, and the overexpression was HL-specific when compared to 116 non-Hodgkin lymphoma tissues. In the analysis of stratified NS-cHL patient samples, expression of FGF2 and SDC1 were 245 fold and 91 fold higher, respectively, in the poor outcome (PO) group than in the good outcome (GO) group. The PO group exhibited higher expression of the HL marker CD30, the macrophage marker CD68, and metastatic markers TGFβ1 and MMP9 compared to the GO group. This expression signature was confirmed by qualitative immunohistochemical and immunofluorescent data. A Kaplan-Meier analysis indicated that samples in which the CD30+ cells carried an FGF2+/SDC1+ immunophenotype showed shortened survival. Analysis of chemo-naive HL blood samples suggested that in the PO group a subset of CD30+ HL cells had entered the circulation. These cells significantly overexpressed FGF2 and SDC1 compared to the GO group. The

    This paper examines the impact of the implementation of a universal free school breakfast policy on meals program participation, attendance, and academic achievement. In 2003, New York City made school breakfast free for all students regardless of income, while increasing the price of lunch for those ineligible for meal subsidies. Using a difference-indifference estimation strategy, we derive plausibly causal estimates of the policy’s impact by exploiting within and between group variation in school meal pricing before and after the policy change. Our estimates suggest that the policy resulted in small increases in breakfast participation both for students who experienced a decrease in the price of breakfast and for free-lunch eligible students who experienced no price change. The latter suggests that universal provision may alter behavior through mechanisms other than price, highlighting the potential merits of universal provision over targeted services. We find limited evidence of policy impacts on academic outcomes. PMID:24465073

    Background and Purpose Due to its sensitivity to deoxyhemoglobin, susceptibility weighted imaging (SWI) enables the visualization of deep medullary veins (DMV) in patients with acute stroke, which are difficult to depict under physiological circumstances. This study assesses the asymmetric appearance of prominent DMV as an independent predictor for stroke severity and outcome. Materials and Methods SWI of 86 patients with acute middle cerebral artery (MCA) stroke were included. A scoring system from 0 (no visible DMV) to 3 (very prominent DMV) was applied for both hemispheres separately. A difference of scores between ipsi- and contralateral side was defined as asymmetric (AMV+). Occurrence of AMV+ was correlated with the National Institute of Health Stroke Scale (NIHSS) Score on admission and discharge, as well as the modified Rankin Scale (mRS) at discharge. Ordinal regression analysis was used to evaluate NIHSS and mRS as predictors of stroke severity, clinical course of disease and outcome. Results 55 patients displayed AMV+ while 31 did not show an asymmetry (AMV–). Median NIHSS on admission was 17 (11–21) in the AMV+ group and 9 (5–15) in the AMV– group (p = 0.001). On discharge median NIHSS was 11 (5–20) for AMV+ and 5 (2–14) for AMV– (p = 0.005). The median mRS at discharge was 4 (3–5) in the AMV+ group and 3 (1–4) in AMV– (p = 0.001). Odds ratio was 3.19 (95% CI: 1.24–8.21) for AMV+ to achieve a higher mRS than AMV– (p = 0.016). Conclusion The asymmetric appearance of DMV on SWI is a fast and easily evaluable parameter for the prediction of stroke severity and can be used as an additional imaging parameter in patients with acute MCA stroke.

    Objective: Mucoepidermoid carcinoma (MEC) is the most common primary malignancy of the salivary glands. Insulin-like growth factor-II mRNA-binding protein-3 (IMP3) is an important prognostic factor in some cancers and a tool that differentiates between benign and malignant pancreatic lesions. This study aimed to identify a relationship between the expression of IMP3 and the outcome of salivary gland MEC, as well as to differentiate MEC from pleomorphic adenoma (PA). Methods:Tissue specimens from 70 cases of salivary gland MEC, 40 cases of PA, and 10 cases with normal salivary gland were examined immunohistochemically for IMP3. The association among the expression of IMP3, clinicopathological characteristics and patient's survival was assessed. Results:IMP3 was present in 51.4% of MEC but absent in PA and normal salivary gland tissues. IMP3 expression was associated with age > 60 years, submandibular gland tumors, tumor size > 4 cm, high-grade tumors, lymph node metastasis, involvement of surgical margins, perineural invasion, distant metastasis, advanced TNM stage, tumor relapse, and death ( P<0.05). Increased expression of IMP3, tumors of the submandibular gland, and lymph node metastasis were independent prognostic factors of -free survival (DFS). In addition, IMP3 was a strong predictor of overall survival (OS) together with distant metastasis and intermediate and high-grade tumors. Conclusions:IMP3 expression is highly important in evaluating the outcome of MEC. IMP3 can be used to differentiate MEC from PA of salivary glands. PMID:27458536

    Purpose In patients suffering from symptomatic peripheral artery disease (PAD), percutaneous revascularization is the treatment of choice. However, restenosis may occur in 10 to 60% in the first year depending on a variety of factors. Small dense low density lipoprotein (sdLDL) particles are associated with an increased risk for cardiovascular events, but their role in the process of restenosis is not known. We conducted a prospective study to analyze the association of sdLDL particles with the outcome of balloon angioplasty in PAD. The composite primary endpoint was defined as improved walking distance and absence of restenosis. Methods Patients with angiographically documented PAD of the lower extremities who were scheduled for lower limb revascularization were consecutively recruited for the study. At baseline and at three month follow-up triglyceride, total cholesterol, LDL size and subclasses and HDL cholesterol and ankle-brachial index (ABI) were measured. Three months after the intervention duplex sonography was performed to detect restenosis. Results Sixty-four patients (53% male) with a mean age of 68.6±9.9 years were included. The proportion of small- dense LDL particles (class III and IV) was significantly lower (33.1±11.0% vs. 39.4±12.1%, p = 0.038) in patients who reached the primary end-point compared with those who did not. Patients with improved walking distance and without restenosis had a significantly higher LDL size at baseline (26.6±1.1 nm vs. 26.1±1.1 nm, p = 0.046) and at follow-up (26.7±1.1 nm vs. 26.2±0.9 nm, p = 0.044) than patients without improvement. Conclusions Small-dense LDL particles are associated with worse early outcome in patients undergoing percutaneous revascularization for symptomatic PAD. PMID:25265512

    During the age of mass migration (1850–1913), one of the largest migration episodes in history, the United States maintained a nearly open border, allowing the study of migrant decisions unhindered by entry restrictions. We estimate the return to migration while accounting for migrant selection by comparing Norway-to-US migrants with their brothers who stayed in Norway in the late nineteenth century. We also compare fathers of migrants and nonmigrants by wealth and occupation. We find that the return to migration was relatively low (70 percent) and that migrants from urban areas were negatively selected from the sending population. “Keep, ancient lands, your storied pomp!” cries she With silent lips. “Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore. Send these, the homeless, tempest-tost to me, I lift my lamp beside the golden door!”——Emma Lazarus (1883)1 PMID:26594052

    Myoferlin (MYOF) is a member of ferlin family of membrane proteins that was originally discovered as a muscle specific protein. Recent studies have shown that myoferlin is also expressed in other cell types including endothelial cells and cancer cells. However, very little is known about the expression and biological role of myoferlin in head and neck cancer. In this study, we examined expression profile of myoferlin in oropharyngeal squamous cell carcinoma (OPSCC) and assessed its correlation with disease progression and patient outcome. In univariate analyses, nuclear MYOF was associated with poor overall survival (p<0.001) and these patients had 5.5 times increased hazard of death (95% Cl 3.4-8.8). Nuclear myoferlin expression was also directly associated with tumor recurrence (p<0.001), perineural invasion (p=0.008), extracapsular spread (p=0.009), higher T-stage (p=0.0015) and distant metastasis (p<0.001). In addition, nuclear MYOF expression was directly associated with IL-6 (p<0.001) and inversely with HPV status (p=0.0014). In a subgroup survival analysis, MYOF nuclear+/IL-6+ group had worst survival (84.6% mortality), whereas MYOF nuclear-/IL-6- had the best survival. Similarly, patients with HPV-negative/MYOF-positive tumors had worse survival compared to HPV-positive/MYOF-negative. Taken together, our results demonstrate for the first time that nuclear myoferlin expression independently predicts poor clinical outcome in OPSCC patients. PMID:26919244

    High-grade epithelial ovarian cancer (HGEOC) is a clinically diverse and molecularly heterogeneous disease comprising subtypes with distinct biological features and outcomes. The receptor tyrosine kinases, expressed by EOC cells, and their ligands, present in the microenvironment, activate signaling pathways, which promote EOC cells dissemination. Herein, we established a molecular link between the presence of Gas6 ligand in the ascites of HGEOCs, the expression and activation of its receptor Axl in ovarian cancer cell lines and biopsies, and the progression of these tumors. We demonstrated that Gas6/Axl signalling converges on the integrin β3 pathway in the presence of the adaptor protein p130Cas, thus inducing tumor cell adhesion to the extracellular matrix and invasion. Accordingly, Axl and p130Cas were significantly co-expressed in HGEOC samples. Clinically, we identified an Axl-associated signature of 62 genes able to portray the HGEOCs with the shortest overall survival. These data biologically characterize a group of HGEOCs and could help guide a more effective therapeutic approach to be taken for these patients. PMID:26356564

    An elevated serum albumin (ALB) and albumin/globulin ratio (AGR) has been reported to be associated with a favorable prognosis for certain malignancies; however, little is known about the prognostic significance of globulin (GLB) in rectal cancer treated with neoadjuvant chemoradiation therapy (NCRT). The purpose of this study was to evaluate whether GLB analysis could predict the prognosis of patients received NCRT. A retrospective cohort of 293 locally advanced rectal cancer patients receiving NCRT followed by radical surgery was recruited between January 2006 and December 2012 at Fudan University Shanghai Cancer Center. Levels for preoperative GLB and ALB were obtained and used to calculate the AGR. Survival analysis was used to evaluate the predictive value of GLB. X-tile program determined 28.50, 36.20 and 1.20 as optimal cut-off value for GLB, ALB and AGR in terms of survival. Univariate and multivariate analysis revealed that low GLB levels were significantly associated with favorable rectal cancer-specific survival (RCSS) (P < 0.05). Conversely, low ALB levels were associated with a significantly worse RCSS (P = 0.010). Collectively, high preoperative GLB level was a significantly unfavorable factor for rectal cancer patients treated with NCRT. This easily obtained variable may serve as a valuable marker to predict the outcomes of such patient population. PMID:26609491

    HHV-6 is an evolving pathogen in the field of AlloHCT. However, the impact of HHV-6 on AlloHCT outcomes remains to be elucidated. We studied the incidence and clinical impact of HHV-6 viremia in children following AlloHCT. One hundred consecutive children were monitored weekly by plasma PCR for the first 180 days following AlloHCT for HHV-6, CMV, EBV, and ADV. HHV-6 viremia was defined as plasma PCR >1000 viral copies/mL. The median age was nine yr. Following AlloHCT, 19% (95% CI 11.3-26.7%) of patients had HHV-6 viremia, with the highest incidence of reactivation (14/19, 73%) occurring during day +15-day +98. The proportion of platelet engraftment by day +180 was lower in patients with HHV-6 viremia (58%) than in those without HHV-6 viremia (82%), p = 0.028. Delay in neutrophil and platelet engraftment was not associated with HHV-6 viremia in multivariate analysis. Similarly, HHV-6 viremia was not associated with TRM in multivariate analysis (p = 0.15). In summary, HHV-6 viremia is prevalent in pediatric AlloHCT recipients. Based on our study results, we recommend that HHV-6 PCR should only be performed on clinical suspicion. PMID:26329541

    Diarrhoea is common in Intensive Care Unit (ICU) patients, with a reported prevalence of 15-38%. Many factors may cause diarrhoea, including Clostridium difficile, drugs (e.g. laxatives, antibiotics) and enteral feeds. Diarrhoea impacts on patient dignity, increases nursing workload and healthcare costs, and exacerbates morbidity through dermal injury, impaired enteral uptake and subsequent fluid imbalance. We analysed a cohort of 9331 consecutive patients admitted to a mixed general intensive care unit to establish the prevalence of diarrhoea in intensive care unit patients, and its relationship with infective aetiology and clinical outcomes. We provide evidence that diarrhoea is common (12.9% (1207/9331) prevalence) in critically ill patients, independently associated with increased intensive care unit length of stay (mean (standard error) 14.8 (0.26) vs 3.2 (0.09) days, p < 0.001) and mortality (22.0% (265/1207) vs 8.7% (705/8124), p < 0.001; adjusted hazard ratio 1.99 (95% CI 1.70-2.32), p < 0.001) compared to patients without diarrhoea even after adjusting for potential confounding factors, and infrequently caused by infective aetiology (112/1207 (9.2%)) such as Clostridium difficile (97/1048 (9.3%) tested) or virological causes (9/172 (5.7%) tested). Our findings suggest non-infective causes of diarrhoea in ICU predominate and pathophysiology of diarrhoea in critically ill patients warrants further investigation. PMID:27094447

    The purpose of this study was to evaluate midterm outcomes after both bone forearm fractures. A retrospective review of patients treated with open reduction and internal fixation (ORIF) at three level 1 trauma centers was completed. Eligible patients were sent three questionnaires: Disabilities of the Arm, Shoulder and Hand (DASH), Short Form-12 (SF-12), and questions about postinjury experience. Twenty-nine patients with an average age of 45 years returned the materials. The forms were completed an average of 60 months after ORIF. The mean DASH was 22 for all respondents. Twenty-one subjects participated in physical therapy (72%). Eight patients (28%) screened positive for posttraumatic stress disorder (PTSD). The mean SF-12 physical component score was 39 and the SF-12 mental component score was 40, both of which were lower than the non-PTSD group, indicating a lower subjective level of health (p < .05). The data suggest that, years after surgery, patients have decreased functional outcomes. PMID:26688986

    Social networking sites (SNSs) have gained substantial popularity among youth in recent years. However, the relationship between the use of these Web-based platforms and mental health problems in children and adolescents is unclear. This study investigated the association between time spent on SNSs and unmet need for mental health support, poor self-rated mental health, and reports of psychological distress and suicidal ideation in a representative sample of middle and high school children in Ottawa, Canada. Data for this study were based on 753 students (55% female; Mage=14.1 years) in grades 7-12 derived from the 2013 Ontario Student Drug Use and Health Survey. Multinomial logistic regression was used to examine the associations between mental health variables and time spent using SNSs. Overall, 25.2% of students reported using SNSs for more than 2 hours every day, 54.3% reported using SNSs for 2 hours or less every day, and 20.5% reported infrequent or no use of SNSs. Students who reported unmet need for mental health support were more likely to report using SNSs for more than 2 hours every day than those with no identified unmet need for mental health support. Daily SNS use of more than 2 hours was also independently associated with poor self-rating of mental health and experiences of high levels of psychological distress and suicidal ideation. The findings suggest that students with poor mental health may be greater users of SNSs. These results indicate an opportunity to enhance the presence of health service providers on SNSs in order to provide support to youth. PMID:26167836

    Status epilepticus is a neurological emergency with significant morbidity and mortality. This study describes the clinical profile, treatment, and predictors of outcome of status epilepticus in a tertiary referral centre in a developing country and aims to highlight the similarities and differences from data available from the western world. A retrospective analysis of data of patients treated for status epilepticus was conducted from prospectively maintained records, between January 2000 and September 2010. The demographic data, clinical profile and investigations (including neuroimaging and EEG), aetiology, treatment, and outcomes were studied and compared with data available from the western world. The analysis included 108 events in 84 patients. A single episode of status epilepticus was treated in 72 patients (86%) and multiple status epilepticus events, ranging from two to six per patient, were managed in 12 patients (14%). Mean age was 24.1±20.3 years and 63% were males. The types of status epilepticus included convulsive status in 98 (90.7%), non-convulsive status in seven (6.5%), and myoclonic status in three (2.8%). The majority of events (60%) were remote symptomatic, 16% were acute symptomatic, 16% were of unexplained aetiology, and 8% were progressive symptomatic. In 85 events (79%), status epilepticus could be aborted with first and second-line drugs. The remaining 23 events (21%) progressed to refractory status epilepticus, among which, 13 (56%) were controlled with continuous intravenous midazolam infusion. Case fatality rate was 11%, neurological sequelae were reported in 22%, and 67% returned to baseline. Acute symptomatic status, older age, altered sensorium at the time of admission, and delayed hospitalisation were predictors of poor outcome. Aetiology was the most important determinant of outcome of status epilepticus, as in reports from the western world, with remote symptomatic aetiology secondary to gliosis being the most common

    Background The aim of the study was to evaluate the oncological and functional outcomes with transoral laser microsurgery (TOLM) of patients with early glottic cancer. Methods We have prospectively evaluated patients treated with TOLM for Tis, T1 or T2 glottic squamous cell carcinoma. Evaluation of oncological outcomes, and voice and functional outcomes was assessed using voice-handicap index 10 (VHI-10) and performance status scale for head & neck cancer patients (PSS-H&N). Predictors of poor voice quality were evaluated using Student’s t-test. Results Thirty patients were included, with 17.7 months mean follow-up. There were no cases of locoregional recurrence. Twelve patients (40%) were considered as having a problematic voice outcome. Four subjects out of 30 (13.3%) had significant problems with understandability of speech. Significant differences (P < 0.05) in VHI-10 score were found with tumor stage and partial resection of the ventricular fold. Conclusions We report excellent oncological and functional outcomes in early glottic cancer treated with TOLM, with advanced tumors and partial resection of the ventricular fold as a surrogate predicting worse voice outcomes.

    When Lyme disease is treated with appropriate antibiotic therapy in the early stages, long-term outcomes are good. However, a few patients have persistent symptoms despite appropriate therapy. Whether these patients' symptoms are any different from those of patients with reinfection is unclear. Our objective was to compare long-term symptoms and functional outcomes of patients with Borrelia burgdorferi reinfection with those of patients with only 1 episode of infection and with no history of infection. We compared outcomes of Lyme reinfection patients, characterized by recurrent erythema migrans (EM) lesions, with those of patients with 1 episode of Lyme disease (Lyme control) and with no history of Lyme disease (non-Lyme control) by retrospective medical record review and a survey consisting of a 36-item Short-Form Health Survey (SF-36) and a 10-item symptom questionnaire. Analysis of variance (ANOVA) for continuous variables and χ(2) analysis for categorical variables were used. In cases of low cell counts, Fisher's exact tests were used. Bonferroni correction was used for multiple comparisons when ANOVA was significant. Reinfection was identified in 23/673 (3.4%) patients who had a diagnosis of Lyme disease in our health system during 2000-2004. Of the 23, 15 had long-term follow-up data and were age- and sex-matched to 45 Lyme control and 60 non-Lyme control group patients. Clinical characteristics were similar in the reinfection and Lyme control groups. SF-36 results were similar between groups for all domains except energy/vitality (VT). The SF-36 domain of VT was significantly different between groups: 63.0 vs. 54.5 vs. 64.5 in the reinfection, Lyme control, and non-Lyme control groups, respectively (p=0.047). Clinical features and long-term outcomes of patients with recurrent EM lesions were similar to those of the control groups and consistent with B. burgdorferi reinfection, not persistent infection. Patients with Lyme reinfection should be treated with

    Identifying oral cancer lesions associated with high risk of relapse and predicting clinical outcome remain challenging questions in clinical practice. Genomic alterations may add prognostic information and indicate biological aggressiveness thereby emphasizing the need for genome-wide profiling of oral cancers. High-resolution array comparative genomic hybridization was performed to delineate the genomic alterations in clinically annotated primary gingivo-buccal complex and tongue cancers (n = 60). The specific genomic alterations so identified were evaluated for their potential clinical relevance. Copy-number changes were observed on chromosomal arms with most frequent gains on 3q (60%), 5p (50%), 7p (50%), 8q (73%), 11q13 (47%), 14q11.2 (47%), and 19p13.3 (58%) and losses on 3p14.2 (55%) and 8p (83%). Univariate statistical analysis with correction for multiple testing revealed chromosomal gain of region 11q22.1–q22.2 and losses of 17p13.3 and 11q23–q25 to be associated with loco-regional recurrence (P = 0.004, P = 0.003, and P = 0.0003) and shorter survival (P = 0.009, P = 0.003, and P 0.0001) respectively. The gain of 11q22 and loss of 11q23-q25 were validated by interphase fluorescent in situ hybridization (I-FISH). This study identifies a tractable number of genomic alterations with few underlying genes that may potentially be utilized as biological markers for prognosis and treatment decisions in oral cancers.

  12. Improving outcome of sensorimotor functions after traumatic spinal cord injury

    2016-01-01

    In the rehabilitation of a patient suffering a spinal cord injury (SCI), the exploitation of neuroplasticity is well established. It can be facilitated through the training of functional movements with technical assistance as needed and can improve outcome after an SCI. The success of such training in individuals with incomplete SCI critically depends on the presence of physiological proprioceptive input to the spinal cord leading to meaningful muscle activations during movement performances. Some actual preclinical approaches to restore function by compensating for the loss of descending input to spinal networks following complete/incomplete SCI are critically discussed in this report. Electrical and pharmacological stimulation of spinal neural networks is still in the experimental stage, and despite promising repair studies in animal models, translations to humans up to now have not been convincing. It is possible that a combination of techniques targeting the promotion of axonal regeneration is necessary to advance the restoration of function. In the future, refinement of animal models according to clinical conditions and requirements may contribute to greater translational success. PMID:27303641

    Objective To investigate the role of executive function (EF) skills, measured by parent-rating and performance-based instruments, as mediators of the effects of gestational age on functional outcomes and behavior symptoms in preterm and full term preschoolers. Patients and methods Children born preterm (n=70; mean gestational age 29.6 weeks and mean birth weight 1365g) were compared to children born full term (n=79) on composite measures of EF (using the Behavior Rating Inventory of Executive Function and a performance-based EF battery), adaptive function, prereading skills, and behavior symptoms. For the entire sample, mediation analyses examined the effect of gestational age on outcomes with EF as mediator. Results Compared to children born full term, children born preterm had significantly higher parent-rated EF scores and lower performance-based EF scores, both indicating more problems; further, children born preterm had lower adaptive function and prereading scores and more problematic behavior. Gestational age contributed to adaptive function, prereading skills, and behavior symptoms for all children. EF acted as a mediator of gestational age for all three outcomes; different patterns emerged for parent-rated and performance-based EF evaluations. For adaptive function, both EF measures significantly mediated effects of gestational age; for prereading skills, only performance-based EF was significant; for behavior symptoms, only parent-rated EF was significant. Conclusions We propose standard assessment of EF, using both parent-rating and performance-based EF measures, in young preterm children and other children at risk of EF impairments. EF skills are measurable, mediate important functional outcomes, and may serve as intervention targets. PMID:24906034

    Cystic fibrosis-related diabetes (CFRD) patients suffer from accelerated rates of pulmonary decline compared to cystic fibrosis (CF) patients with normal glucose tolerance (NGT). However, the mechanisms underlying this difference are unknown. While CFRD is associated with increased respiratory infections, a link between infection and enhanced pulmonary dysfunction remains unclear. The development of glucose intolerance is spectral, resulting in impaired glucose tolerance (IGT) prior to the diagnosis of CFRD. Inclusion of IGT patients within the NGT group may diminish the ability to identify correlations with CFRD. With this in mind, this study aimed to determine if the association between CFRD and respiratory infections is correlated with pulmonary decline. Respiratory cultures from 234 CF patients with confirmed diagnosis of NGT or CFRD were analyzed to measure rates of infection, focusing on the two most prevalent bacteria in CF, Staphylococcus aureus and Pseudomonas aeruginosa. Infection status was correlated with pulmonary function and confounding clinical variables including age, gender, blood glucose levels, and CF transmembrane conductance regulator (CFTR) phenotype were considered in multivariate analyses. CFRD patients, particularly those with extremely high blood glucose levels, were more likely than NGT patients to be co-infected with S. aureus and P. aeruginosa, compared to infection with only one pathogen. Co-infection was associated with decreased lung function and increased frequency of pulmonary exacerbations, even after adjustment for confounding variables. Alterations in the microbial community composition, as opposed to the presence of a single pathogen, may account for greater pulmonary decline in CFRD patients. PMID:26993289

    Introduction: Fracture of the penis is a rare urological emergency which occurs as a result of abrupt trauma to an erect penis. There is paucity of data regarding long-term sexual function or erectile potency following fracture of the penis. The aim of this study is to objectively assess the overall sexual function following fracture of the penis. Methods: A retrospective analysis of 21 penile fractures was performed. A voluntary telephone questionnaire was performed to assess long term outcomes using three validated questionnaires-the Erection Hardness Grading Scale, the International Index of Erectile Function (IIEF-5) and the Brief Male Sexual Function inventory (BMSFI). Results: The mean age was 33.1 years (range: 19–63). The median follow up was 46 months (range: 3–144). All fractures were a result of sexual misadventure and all were surgically repaired. There were two concomitant urethral injuries. Seventeen patients were contactable. Fourteen patients demonstrated no evidence of erectile dysfunction (ED) (IIEF-5>22), 1 patient reported symptoms of mild ED (IIEF-5, 17–21) and one patient reported mild to moderate ED (IIEF-5, 12–16). No patients reported insufficient erection for penetration (EHGS: 1 or 2). Regarding the overall BMSFI, 13 (83%) patients were mostly satisfied or very satisfied with their sex life within the previous month. Conclusion: In a small surgical series of men with penile fracture managed within a short time frame from presentation, we demonstrate erectile potency is maintained. Long-term overall sexual satisfaction is promising. PMID:24032060

    Motor evoked potentials after magnetic transcranial stimulation and the excitability of the motor cortex to increasing magnetic stimulus intensities were evaluated in six patients with hemiparesis after ischaemic stroke within 8 hours after stroke. The latencies of motor evoked potentials were normal in all patients. After stimulation of the ischaemic hemisphere we obtained responses comparable with the contralateral ones in two patients (mean NIH score 2 (SD 0)) and this group was completely asymptomatic after 15 days (NIH score 0). In four patients the excitability of the motor cortex involved by the ischaemia was reduced and magnetic motor threshold was higher than that of the spared motor cortex. This finding was associated with a poor motor recovery and the NIH score after 15 days was unchanged (NIH score 1.75 (SD 1.5)). The present data suggest that the evaluation of the excitability of motor cortex may offer a mean of predicting functional outcome following stroke. PMID:10461555

    Background: Hemorrhage is a leading cause of preventable trauma death. In this study, we used the reverse shock index (RSI), a ratio of systolic blood pressure (SBP) to heart rate (HR), to evaluate the hemodynamic stability of trauma patients. As an SBP lower than the HR (RSI < 1) may indicate hemodynamic instability, the objective of this study was to assess the associated complications in trauma patients with an RSI < 1 upon arrival at the emergency department (ED) (indicated as (A)RSI) and at the time of departure from the ED (indicated as (L)RSI) to the operative room or for admission. Methods: Data obtained from all 16,548 hospitalized patients recorded in the trauma registry system at a Level I trauma center between January 2009 and December 2013 were retrospectively reviewed. A total of 10,234 adult trauma patients aged ≥20 were enrolled and subsequently divided into four groups: Group I, (A)RSI ≥ 1 and (L)RSI ≥ 1 (n = 9827); Group II, (A)RSI ≥ 1 and (L)RSI < 1 (n = 76); Group III, (A)RSI < 1 and (L)RSI ≥ 1 (n = 251); and Group IV, (A)RSI < 1 and (L)RSI < 1 (n = 80). Pearson’s χ2 test, Fisher’s exact test, or independent Student’s t-test was conducted to compare trauma patients in Groups II, III, and IV with those in Group I. Results: Patients in Groups II, III, and IV had a higher injury severity score and underwent a higher number of procedures, including intubation, chest tube insertion, and blood transfusion, than Group I patients. Additionally, patients of these groups had increased hospital length of stay (16.3 days, 14.9 days, and 22.0 days, respectively), proportion of patients admitted to the intensive care unit (ICU) (48.7%, 43.0%, and 62.5%, respectively), and in-hospital mortality (19.7%, 7.6%, and 27.5%, respectively). Although the trauma patients who had a SBP < 90 mmHg either upon arrival at or departure from the ED also present a more severe injury and poor outcome, those patients who had a SBP ≥ 90 mmHg but an RSI < 1 had

    Due to their young age young stroke survivors have to cope with a dramatic impact on their life for the decades to come. We investigated the sex-specific very long-term functional outcome after transient ischemic attack (TIA) and ischemic stroke (IS) in adults aged 18-50 years. This study is part of a cohort study among 619 first-ever young ischemic stroke patients, admitted to our department between January 1, 1980 and November 1, 2010. Functional outcome was assessed during follow-up in 2009-2011 and in 2014-2015 with the modified Rankin Scale (mRS) and instrumental Activities of Daily Living scale (iADL). Risk factors for a poor functional outcome (mRS > 2 and iADL < 8) were calculated by logistic regression analysis. After a mean follow-up of 13.9 (SD 8.2) years, 24.5 % of TIA patients and 44.7 % of IS patients had a poor functional outcome (mRS > 2). When assessing the survivors, 15.2 % of TIA patients and 22.9 % of IS patients had a poor outcome as assessed by iADL. The strongest baseline predictors of poor outcome were female sex (OR 2.7, 95 % CI 1.5-5.0) and baseline NIHSS (OR 1.1, 95 % CI 1.1-1.2 per point increase). In conclusion, 14 years after an ischemic cerebrovascular event in young adults, one out of five IS survivors and one out of ten TIA survivors is still dependent in daily life, with a two to threefold higher risk of a poor outcome in women. This includes a period of life, during which important decisions regarding work and family life have to be made. PMID:27039389

    Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a devastating autosomal recessive disorder due to mutations in TYMP, which cause loss of function of thymidine phosphorylase (TP), nucleoside accumulation in plasma and tissues and mitochondrial dysfunction. The clinical picture includes progressive gastrointestinal dysmotility, cachexia, ptosis and ophthalmoparesis, peripheral neuropathy and diffuse leukoencephalopathy, which usually lead to death in early adulthood. Therapeutic options are currently available in clinical practice (allogeneic hematopoietic stem cell transplantation and carrier erythrocyte entrapped TP therapy) and newer, promising therapies are expected in the near future. However, successful treatment is strictly related to early diagnosis. We report on an incomplete MNGIE phenotype in a young man harboring the novel heterozygote c.199 C>T (Q67X) mutation in exon 2, and the previously reported c.866 A>C (E289A) mutation in exon 7 in TYMP. The correct diagnosis was achieved many years after the onset of symptoms and unfortunately, the patient died soon after diagnosis because of multiorgan failure due to severe malnutrition and cachexia before any therapeutic option could be tried. To date, early diagnosis is essential to ensure that patients have the opportunity to be treated. MNGIE should be suspected in all patients who present with both gastrointestinal and nervous system involvement, even if the classical complete phenotype is lacking. PMID:23341816

    BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B) is a member of the spindle assembly checkpoint protein family, which has been proven to be associated with many kinds of cancers. The aim of this study was to investigate whether BUB1B was correlated with progression and prognosis in patients with prostate cancer (PCa) and how BUB1B regulated the proliferation, migration, and invasion of PCa cell lines. Compared to benign prostate cells and tissues, both messenger RNA and protein expressions of BUB1B were statistically increased in PCa cell lines and tumor tissues. In vitro studies revealed that BUB1B overexpression enhanced the proliferation, migration, and invasion ability of PCa cell lines, whereas depletion of BUB1B did not affect the cell functions. Microarray analysis showed the positive staining of BUB1B was upregulated in the higher Gleason score group, which also correlated with advanced clinicopathological stage, higher serum prostate-specific antigen, metastasis, overall survival, and prostate-specific antigen failure. Furthermore, the survival analysis indicated that high expression of BUB1B was an independent predictor for shorter biochemical recurrence-free survival, which had no effect on overall survival. BUB1B plays an important role in tumor growth and progression, which can lead to its use as a potential biomarker for the diagnosis and prognosis of PCa. PMID:27143916

    BACKGROUND Many patients have symptoms suggestive of coronary artery disease (CAD) and are often evaluated with the use of diagnostic testing, although there are limited data from randomized trials to guide care. METHODS We randomly assigned 10,003 symptomatic patients to a strategy of initial anatomical testing with the use of coronary computed tomographic angiography (CTA) or to functional testing (exercise electrocardiography, nuclear stress testing, or stress echocardiography). The composite primary end point was death, myocardial infarction, hospitalization for unstable angina, or major procedural complication. Secondary end points included invasive cardiac catheterization that did not show obstructive CAD and radiation exposure. RESULTS The mean age of the patients was 60.8±8.3 years, 52.7% were women, and 87.7% had chest pain or dyspnea on exertion. The mean pretest likelihood of obstructive CAD was 53.3±21.4%. Over a median follow-up period of 25 months, a primary end-point event occurred in 164 of 4996 patients in the CTA group (3.3%) and in 151 of 5007 (3.0%) in the functional-testing group (adjusted hazard ratio, 1.04; 95% confidence interval, 0.83 to 1.29; P = 0.75). CTA was associated with fewer catheterizations showing no obstructive CAD than was functional testing (3.4% vs. 4.3%, P = 0.02), although more patients in the CTA group underwent catheterization within 90 days after randomization (12.2% vs. 8.1%). The median cumulative radiation exposure per patient was lower in the CTA group than in the functional-testing group (10.0 mSv vs. 11.3 mSv), but 32.6% of the patients in the functional-testing group had no exposure, so the overall exposure was higher in the CTA group (mean, 12.0 mSv vs. 10.1 mSv; P<0.001). CONCLUSIONS In symptomatic patients with suspected CAD who required noninvasive testing, a strategy of initial CTA, as compared with functional testing, did not improve clinical outcomes over a median follow-up of 2 years.

    Indole, which is produced from l-tryptophan by commensal bacteria expressing tryptophanase, not only is an important intercellular signal in microbial communities, but also modulates mucosal barrier function and expression of pro- and anti-inflammatory genes by intestinal epithelial cells. Here, we hypothesized that decreased urinary excretion of 3-indoxyl sulfate (3-IS), the major conjugate of indole found in humans, may be a marker of gut microbiota disruption and increased risk of developing gastrointestinal (GI) graft-versus-host-disease. Using liquid chromatography/tandem mass spectrometry, 3-IS was determined in urine specimens collected weekly within the first 28 days after allogeneic stem cell transplantation (ASCT) in 131 patients. Low 3-IS levels within the first 10 days after ASCT were associated with significantly higher transplant-related mortality (P = .017) and worse overall survival (P = .05) 1 year after ASCT. Least absolute shrinkage and selection operator regression models trained on log-normalized counts of 763 operational taxonomic units derived from next-generation sequencing of the hypervariable V3 region of the 16S ribosomal RNA gene showed members of the families of Lachnospiraceae and Ruminococcaceae of the class of Clostridia to be associated with high urinary 3-IS levels, whereas members of the class of Bacilli were associated with low 3-IS levels. Risk factors of early suppression of 3-IS levels were the type of GI decontamination (P = .01), early onset of antibiotic treatment (P = .001), and recipient NOD2/CARD15 genotype (P = .04). In conclusion, our findings underscore the relevance of microbiota-derived indole and metabolites thereof in mucosal integrity and protection from inflammation. PMID:26209659

    The aim of this study was to investigate the calcyphosine (CAPS) expression in human colorectal cancer (CRC) and to explore its clinical and prognostic significances. CAPS expression was measured by Western blot, real-time polymerase chain reaction analysis, and immunohistochemistry. The relationships between the CAPS expression levels and the clinicopathological factors were investigated. The Kaplan–Meier method and log-rank test were used to investigate the overall survival of the patients. Moreover, the effects of CAPS on biological roles of CRC cells were also evaluated by MTT assay, colony formation assay, and transwell assay. CAPS was significantly overexpressed in cancerous tissue and CRC cell lines compared with adjacent nontumor tissue and a normal human intestinal epithelial cell line. Overexpression of CAPS was significantly associated with histological grade (P=0.004), invasive depth (P<0.001), lymph node metastasis (P=0.003), tumor node metastasis stage (P=0.017), and distant metastasis (P=0.042). Furthermore, silencing of CAPS expression in CRC cells inhibited their proliferation, colony formation, migration, and invasion. Kaplan–Meier survival analysis showed that high CAPS expression might demonstrate poor prognosis in CRC patients. Cox regression analysis revealed that CAPS expression was an independent prognostic factor of CRC. Our data suggested that the upregulation of CAPS might play a role in the carcinogenesis and progression of CRC. CAPS could be used as a potential diagnostic factor and be an independent good prognostic indicator for CRC patients. PMID:26889086

    Medialization thyroplasty (MT) is the most widely used laryngeal framework phonosurgical procedure for managing glottic incompetence secondary to unilateral vocal fold paralysis (UVFP). The aim of the study was to evaluate the functional outcomes of MT in 32 UVFP patients, comparing multidimensional perceptual and instrumental measures of voice before and after surgery, and to evaluate how close to normal that postoperative voice measure became. Video laryngostroboscopy (VLS), auditory perceptive evaluation of voice, the patients' self-evaluation of hoarseness on the Visual Analogue Scale (VAS) and calculation of the Voice Handicap Index (VHI), analysis of objective acoustic voice parameters, quantitative assessment of phonetograms and measurement of maximum phonation time were conducted. Vocal function was evaluated before the surgery and for the period from 1 month to 3 years (Mo 1.0 month; Me 2.0 months) after MT. VLS confirmed remarkable medialization of the paralyzed vocal fold. As a consequence, hoarseness and breathiness were found to be significantly decreased after MT. Pitch and intensity range and phonetogram area were significantly increased. A significant decrease of jitter, shimmer and normalized noise energy reflected improvement of the stability of acoustic signal and a more efficient pattern of phonation. Thus, the perceptual and acoustic voice parameters studied showed statistically significant differences (P < 0.001) between preoperative and postoperative voices, and these objective measurements of voice changes provided accurate and documentary evidence of the results of surgical treatment. A high degree of patient satisfaction with the MT was confirmed by a significant decrease of VHI and hoarseness on VAS. Thus, results of the present investigation confirm the functionality and effectiveness of MT in patient voice rehabilitation with UVFP. However, the means of acoustic voice parameters measured in the study did not reach normal limits

    Schizophrenia and bipolar disorder have been associated with shared and distinct emotion processing abnormalities. Initial findings indicate that these disorders differ with respect to the domain of emotional intelligence (EI). Individuals with schizophrenia display deficits on performance measures of EI, whereas those with bipolar disorder do not. However, no research has examined patients’ subjective beliefs about their own EI (referred to as “perceived EI”). This study examined perceived EI, assessed with the Trait Meta-Mood Scale (TMMS), and its clinical and functional correlates in outpatients with schizophrenia (n = 35) or bipolar disorder I (n = 38) and matched healthy controls (n = 35). The TMMS includes three subscales that assess beliefs about one’s ability to attend to (Attention to Feelings), understand (Clarity of Feelings), and repair emotions (Mood Repair). Participants in the clinical groups also completed community functioning and symptom assessments. Both clinical groups reported significantly lower perceived EI than controls, but did not differ from each other. Higher total TMMS correlated with higher levels of independent living in the schizophrenia group (r = .36) and better social functioning in the bipolar group (r = .61). In addition, although higher Attention to Feelings scores correlated with greater psychiatric symptoms in the schizophrenia group, higher scores across all subscales correlated with less manic symptoms in the bipolar group. The findings suggest that perceived EI is impaired and related to community functioning in both disorders. PMID:25579055

    Background Epithelial cell adhesion molecule (epcam) is a multifunctional transmembrane glycoprotein expressed on both normal epithelium and epithelial neoplasms such as gastric, breast, and renal carcinomas. Recent studies have proposed that the proteolytic cleavage of the intracellular domain of epcam (epcam-icd) can trigger signalling cascades leading to aggressive tumour behavior. The expression profile of epcam-icd has not been elucidated for primary colorectal carcinoma. In the present study, we examined epcam-icd immunohistochemical staining in a large cohort of patients with primary colorectal adenocarcinoma and assessed its performance as a potential prognostic marker. Methods Immunohistochemical staining for epcam-icd was assessed on tissue microarrays consisting of 137 primary colorectal adenocarcinoma samples. Intensity of staining for each core was scored by 3 independent pathologists. The membranous epcam-icd staining score was calculated as a weighted average from 3 core samples per tumour. Univariate analysis of the average scores and clinical outcome measures was performed. Results The level of membranous epcam-icd staining was positively associated with well-differentiated tumours (p = 0.01); low preoperative carcinoembryonic antigen (p = 0.001); and several measures of survival, including 2-year (p = 0.02) and 5-year survival (p = 0.05), and length of time post-diagnosis (p = 0.03). A number of other variables—including stage, grade, and lymph node status—showed correlations with epcam staining and markers of poor outcome, but did not reach statistical significance. Conclusions Low membranous epcam-icd staining might be a useful marker to identify tumours with aggressive clinical behavior and potential poor prognosis and might help to select candidates who could potentially benefit from treatment targeting epcam.

    This study was performed to investigate the effect of of transdermal testosterone gel (TTG) on controlled ovarian stimulation (COS) and IVF outcomes and ovarian morphology according to pretreatment duration in poor responders. A total of 120 women were recruited for this pilot study. They were randomized into control, 2 weeks, 3 weeks or 4 weeks TTG treatment groups. For three TTG treatment groups, 12.5 mg TTG was applied daily for 2 weeks, 3 weeks or 4 weeks in preceding period of study stimulation cycle. After 3 weeks of TTG pretreatment, significant increase of antral follicle count (AFC) and significant decreases of mean follicular diameter (MFD) and resistance index (RI) value of ovarian stromal artery were observed (p=0.026, p<0.001, p<0.01, respectively). The total dose of rhFSH administered for COS significantly decreased after 3 and 4 weeks TTG treatment both compared with control group (p<0.001, p<0.001). The numbers of oocytes retrieved and mature oocytes were significanty higher in 3 and 4 weeks TTG treatment groups than control group (p<0.001, p<0.001 in the number of oocytes retrieved; p<0.001, p<0.001 in the number of mature oocytes). The clinical pregnancy rate and live birth rate were increased only in 4 weeks TTG treatment group compared with control group (p=0.030 and p=0.042, respectively). These data demonstrated that TTG pretreatment for 3 to 4 weeks increases AFC and ovarian stromal blood flow, thereby potentially improving the ovarian response to COS and IVF outcome in poor responders undergoing IVF/ICSI.

    Stormwater runoff causes environmental problems such as flooding, soil erosion, and water pollution. Conventional stormwater management has focused primarily on flood reduction, while a new generation of decentralized stormwater solutions yields ancillary benefits such as healthier aquatic habitat, improved surface water quality, and increased water table recharge. Previous research has estimated values for flood reduction from stormwater management, but no estimates exist for the willingness to pay (WTP) for some of the other environmental benefits of alternative approaches to stormwater control. This paper uses a choice experiment survey of households in Champaign-Urbana, Illinois, to estimate the values of several attributes of stormwater management outcomes. We analyzed data from 131 surveyed households in randomly selected neighborhoods. We find that people value reduced basement flooding more than reductions in yard or street flooding, but WTP for basement flood reduction in the area only exists if individuals are currently experiencing significant flooding themselves. Citizens value both improved water quality and improved hydrologic function and aquatic habitat from runoff reduction. Thus, widespread investment in low impact development stormwater solutions could have very large total benefits, and stormwater managers should be wary of policies and infrastructure plans that reduce flooding at the expense of water quality and aquatic habitat.

    . Results: The results were assessed using 100 point scoring system where union allotted 30 points and 60 points allotted for angulations (10), elbow motion (10), shoulder abduction (10), shortening (5), rotation (5), absence of infection (10), absence of nerve palsy during treatment (10). Remaining 10 points were allotted for five items with two points each. They were the absence of skin sore, absence of vascular problem, absence of reflex sympathetic dystrophy (RSD), recovery of paralyzed nerve during injury and recovery of paralyzed nerve during treatment. Results were considered excellent with 90 and above, good with 80–89, fair with 70–79 and poor below 70 point. Results at 6 months were excellent in 43.94% (n = 29), good in 42.42% (n = 28), fair in 9.1% (n = 6), poor in 4.55% (n = 3). Union took place in 98.48% (n = 65) with an average of 10.3 weeks (range 6–16 weeks). 87.5% (n = 7) paralyzed radial nerve recovered. All wounds healed. Four patients had transient skin problem. One patient with mid shaft fracture had nonunion due to the muscle interposition. Conclusion: Modified functional cast brace is one of the options in treatment for humeral shaft fractures as it can be applied on the 1st day of the presentation in most of the situations. Simple objective scoring system was useful particularly in uneducated patients. PMID:26229161

    For many years, Severe Combined Immune Deficiency (SCID) diseases, characterized by virtual lack of circulating T cells and severe predisposition to infections since early in life, have been considered the prototypic forms of genetic defects of T cell development. More recently, advances in genome sequencing have allowed identification of a growing number of gene defects that cause severe, but incomplete, defects in T cell development and/or function. Along with recurrent and severe infections, and especially cutaneous viral infections, the clinical phenotype of these conditions is characterized by prominent immune dysregulation. PMID:23465662

    An accurate prediction of system-specific recovery after stroke is essential to provide rehabilitation therapy based on the individual needs. We explored the usefulness of functional magnetic resonance imaging scans from an auditory language comprehension experiment to predict individual language recovery in 21 aphasic stroke patients. Subjects with an at least moderate language impairment received extensive language testing 2 weeks and 6 months after left-hemispheric stroke. A multivariate machine learning technique was used to predict language outcome 6 months after stroke. In addition, we aimed to predict the degree of language improvement over 6 months. 76% of patients were correctly separated into those with good and bad language performance 6 months after stroke when based on functional magnetic resonance imaging data from language relevant areas. Accuracy further improved (86% correct assignments) when age and language score were entered alongside functional magnetic resonance imaging data into the fully automatic classifier. A similar accuracy was reached when predicting the degree of language improvement based on imaging, age and language performance. No prediction better than chance level was achieved when exploring the usefulness of diffusion weighted imaging as well as functional magnetic resonance imaging acquired two days after stroke. This study demonstrates the high potential of current machine learning techniques to predict system-specific clinical outcome even for a disease as heterogeneous as stroke. Best prediction of language recovery is achieved when the brain activation potential after system-specific stimulation is assessed in the second week post stroke. More intensive early rehabilitation could be provided for those with a predicted poor recovery and the extension to other systems, for example, motor and attention seems feasible. PMID:20299389

    Gated cardiac scanning was used to evaluate the hemodynamic effects of encainide in 19 patients (1 woman) with complex ventricular arrhythmia and depressed left ventricular (LV) function (ejection fraction less than 45%). Patients were 36 to 80 years old (average 61). All were candidates for long-term encainide therapy after having failed with currently available antiarrhythmics. Sixty-three percent had congestive heart failure before they received encainide. All were evaluated in the hospital before encainide therapy by a gated cardiac scan performed at least 3 days after discontinuing all antiarrhythmic drugs. Patients received oral encainide in doses of 75 to 200 mg. Gated cardiac scans were repeated 1 to 2 weeks later when an 80% reduction in frequency of premature ventricular complexes was observed on a 24-hour Holter recording. No patient had worsening of congestive heart failure during encainide therapy. Encainide did not significantly affect ejection fraction, which averaged 22 +/- 10% before and 25 +/- 14% (SD) after encainide (difference not significant (NS)). Other hemodynamic variables, including heart rate, blood pressure, stroke volume and end-diastolic volume, remained unchanged during encainide therapy. Digoxin blood levels in 10 patients averaged 1.04 +/- 0.43 before and 1.22 +/- 0.47 mg/ml (NS) during encainide therapy. Thus, encainide given orally in clinically effective doses does not appear to have significant hemodynamic effects in patients with ventricular arrhythmia and depressed LV function.

    A prospective single blinded interventional study was held in Otorhinolaryngology Clinic, Universiti Kebangsaan Malaysia Medical Centre in August 2010 until November 2012 to evaluate the functional outcome of septorhinoplasty objectively and subjectively. Objective assessment was done using rhinomanometry and subjective assessment using Nasal Obstruction Symptoms Evaluation (NOSE) scale and Health-Related Quality of Life Questionnaires (HRQOL) in Rhino Surgery. All measurements were taken preoperatively and 3 months postoperatively. A total of 29 patients were enrolled and completed the study. Septorhinoplasty was commonly performed in Malays and Indians and rare amongst Chinese, with age ranged from 18 to 54 years. Majority had no history of trauma. Twisted nose was the most common external nose abnormality followed by crooked and saddle nose. All patients had internal valve insufficiency. There were significant improvement of the total and of all the parameters in the NOSE scale post septorhinoplasty (p < 0.05). Furthermore, there were significant improvement in total and in all parameters in HRQOL score post septorhinoplasty (p < 0.05). There were improvements in the rhinomanometry data bilaterally during inspiration and expiration, but were not statistically significant (p > 0.05). Significant correlations were noted in the improvement between the two subjective assessments (NOSE scale and HRQOL score). However, there was no significant correlation in the improvement between the subjective (NOSE scale and HRQOL score) with objective (rhinomanometry score) assessments. Septorhinoplasty improves the nasal airflow and quality of life of patients with nasal obstruction. PMID:27340641

    Accurate language localization expands surgical treatment options for epilepsy patients and reduces the risk of postsurgery language deficits. Electrical cortical stimulation mapping (ESM) is considered to be the clinical gold standard for language localization. While ESM affords clinically valuable results, it can be poorly tolerated by children, requires active participation and compliance, carries a risk of inducing seizures, is highly time consuming, and is labor intensive. Given these limitations, alternative and/or complementary functional localization methods such as analysis of electrocorticographic (ECoG) activity in high gamma frequency band in real time are needed to precisely identify eloquent cortex in children. In this case report, the authors examined 1) the use of real-time functional mapping (RTFM) for language localization in a high gamma frequency band derived from ECoG to guide surgery in an epileptic pediatric patient and 2) the relationship of RTFM mapping results to postsurgical language outcomes. The authors found that RTFM demonstrated relatively high sensitivity (75%) and high specificity (90%) when compared with ESM in a “next-neighbor” analysis. While overlapping with ESM in the superior temporal region, RTFM showed a few other areas of activation related to expressive language function, areas that were eventually resected during the surgery. The authors speculate that this resection may be associated with observed postsurgical expressive language deficits. With additional validation in more subjects, this finding would suggest that surgical planning and associated assessment of the risk/benefit ratio would benefit from information provided by RTFM mapping.

    Background and Purpose Systemic Inflammatory Response (SIRS) is a generalized inflammatory state. The primary goal of the study was to determine if differences exist in outcomes in SIRS and non-SIRS IV tPA treated patients. Methods Consecutive patients were retrospectively reviewed for evidence of SIRS during their admission. SIRS was defined as the presence of two or more: body temperature <36° C or >38° C, HR >90, respiratory rate >20 and WBC <4,000/mm or >12,000mm or >10% bands. Patients diagnosed with infection (via positive culture) were excluded. Results Out of 241 patients, 44 had evidence of SIRS (18%). Adjusting for pre-tPA NIHSS, age, and race, SIRS remained a predictor of poor functional outcome at discharge (OR= 2.58, 95% CI, 1.16 – 5.73, p=0.0197). Conclusion In our sample of tPA treated patients, almost 1 out of 5 patients developed SIRS. Further, we found the presence of SIRS to be associated with poor short-term functional outcomes and prolonged length of stay. PMID:23704110

    Purpose Correlations between maximum flexion and functional outcomes in total knee arthroplasty (TKA) patients are reportedly weak. We investigated whether there are differences between passive maximum flexion in nonweight bearing and other types of maximum flexion and whether the type of maximum flexion correlates with functional outcomes. Materials and Methods A total of 210 patients (359 knees) underwent preoperative evaluation and postoperative follow-up evaluations (6, 12, and 24 months) for the assessment of clinical outcomes including maximum knee flexion. Maximum flexion was measured under five conditions: passive nonweight bearing, passive weight bearing, active nonweight bearing, and active weight bearing with or without arm support. Data were analyzed for relationships between passive maximum flexion in nonweight bearing by Pearson correlation analyses, and a variance comparison between measurement techniques via paired t test. Results We observed substantial differences between passive maximum flexion in nonweight bearing and the other four maximum flexion types. At all time points, passive maximum flexion in nonweight bearing correlated poorly with active maximum flexion in weight bearing with or without arm support. Active maximum flexion in weight bearing better correlated with functional outcomes than the other maximum flexion types. Conclusions Our study suggests active maximum flexion in weight bearing should be reported together with passive maximum flexion in nonweight bearing in research on the knee motion arc after TKA.

    Hypoxia-inducible factors (HIFs) are differentially regulated in tumor cells. While the current paradigm supports post-translational regulation of the HIF-α subunits, we recently showed that hypoxic HIF-2α is also transcriptionally regulated via insulin-like growth factor (IGF)-II in the childhood tumor neuroblastoma. Here, we demonstrate that transcriptional regulation of HIF-2α seems to be restricted to neural cell-derived tumors, while HIF-1α is canonically regulated at the post-translational level uniformly across different tumor forms. Enhanced expression of HIF2A mRNA at hypoxia is due to de novo transcription rather than increased mRNA stability, and chemical stabilization of the HIF-α proteins at oxygen-rich conditions unexpectedly leads to increased HIF2A transcription. The enhanced HIF2A levels do not seem to be dependent on active HIF-1. Using a transcriptome array approach, we identified members of the Peroxisome proliferator-activated receptor gamma coactivator (PGC)/Estrogen-related receptor (ERR) complex families as potential regulators of HIF2A. Knockdown or inhibition of one of the members, ERRα, leads to decreased expression of HIF2A, and high expression of the ERRα gene ESRRA correlates with poor overall and progression-free survival in a clinical neuroblastoma material consisting of 88 tumors. Thus, targeting of ERRα and pathways regulating transcriptional HIF-2α are promising therapeutic avenues in neuroblastoma. - Highlights: • Transcriptional control of HIF-2α is restricted to neural cell-derived tumors. • Enhanced transcription of HIF2A is not due to increased mRNA stability. • Chemical stabilization of the HIF-α subunits leads to increased HIF2A transcription. • ERRα regulates HIF2A mRNA expression in neuroblastoma. • High expression of ESRRA correlates to poor outcome in neuroblastoma.

    While ceftriaxone 1 g q24h is commonly used for hospitalized patients with community-acquired pneumonia (CAP), the prescribing information recommends 2-4 g a day to treat methicillin-susceptible Staphylococcus aureus (MSSA). Similarly, recent pharmacodynamic analyses suggest shortcomings of 1 g q24h against the bulk of the MSSA. We evaluated the outcomes of empiric ceftriaxone 1 g q24h ± azithromycin in patients with MSSA pneumonia, as compared with Streptococcus pneumoniae. Adult patients admitted to Hartford Hospital from 1/2005 to 12/2014 with respiratory culture for MSSA or S. pneumoniae were considered for inclusion. Non-ICU, CAP patients were included. Early clinical failure (ECF) was defined as persistent signs/symptoms or change of antibiotic due to poor response at 72-96 h. A multivariate analysis was performed to evaluate predictors of ECF. Over the study period, 403 MSSA and 227 S. pneumoniae positive respiratory cultures were identified. The majority of patients were excluded due to the following: no signs/symptoms of pneumonia, hospital-acquired pneumonia, alternative antibiotics, and polymicrobial infection. Thirty-nine patients met inclusion/exclusion criteria. All but three patients in the S. pneumoniae group received ceftriaxone + azithromycin. ECF was greater in the MSSA group (53 vs. 4 %, P = 0.003), as was length of stay (7.5 ± 5.4 vs. 4.6 ± 3.3 days, P = 0.006). When controlling for disease severity and macrolide non-susceptibility in a multivariate analysis, MSSA was significantly correlated with ECF (OR 12.3, 95 % CI 0.8-188.8). Poor clinical outcomes were observed in patients empirically treated with ceftriaxone ± azithromycin for MSSA CAP. Despite the popularity of ceftriaxone 1 g q24h, these data suggest this dose or compound may be inadequate for CAP caused by MSSA. PMID:26531307

    The introduction of Rituximab has improved the outcome and survival rates of Burkitt lymphoma (BL). However, early relapse and refractoriness are current limitations of BL treatment and new biological factors affecting the outcome of these patients have not been explored. This study aimed to identify the presence of genomic changes that could predict the response to new therapies in BL. Forty adolescent and adult BL patients treated with the Dose-Intensive Chemotherapy Including Rituximab (Burkimab) protocol (Spanish Programme for the Study and Treatment of Haematological Malignancies; PETHEMA) were analysed using array-based comparative genomic hybridization (CGH). In addition, the presence of TP53, TCF3 (E2A), ID3 and GNA13 mutations was assessed by next-generation sequencing (NGS). Ninety-seven per cent of the patients harboured genomic imbalances. Losses on 11q, 13q, 15q or 17p were associated with a poor response to Burkimab therapy (P = 0·038), shorter progression-free survival (PFS; P = 0·007) and overall survival (OS; P = 0·009). The integrative analysis of array-CGH and NGS showed that 26·3% (5/19) and 36·8% (7/19) of patients carried alterations in the TP53 and TCF3 genes, respectively. TP53 alterations were associated with shorter PFS (P = 0·011) while TCF3 alterations were associated with shorter OS (P = 0·032). Genetic studies could be used for risk stratification of BL patients treated with the Burkimab protocol. PMID:26567765

    While the epidemiologic association between hepatitis B virus (HBV) infection and diffuse large B-cell lymphoma (DLBCL) is established, little is known more than this epidemiologic evidence. We studied a cohort of 587 patients with DLBCL for HBV infection status, clinicopathologic features, and the immunoglobulin variable region in HBV surface antigen (HBsAg)-positive patients. Eighty-one (81/587, 13.8%) patients were HBsAg-positive. Compared with HBsAg-negative DLBCL, HBsAg-positive DLBCL displayed a younger median onset age (45 vs. 55 years), more frequent involvement of spleen or retroperitoneal lymph node (40.7% vs. 16.0% and 61.7% vs. 31.0% respectively, both p < 0.001), more advanced disease (stage III/IV: 76.5% vs 59.5%, p = 0.003), and significantly worse outcome (2-year overall survival: 47% versus 70%, p < 0.001). In HBsAg-positive DLBCL patients, almost all (45/47, 96%) amino acid sequences of heavy and light chain complementarity determining region 3 exhibited a high homology to antibodies specific for HBsAg, and the majority (45/50, 90%) of IgHV and IgLV genes were mutated. We conclude that 13.8% of DLBCL cases are HBV-associated in HBV-endemic China and show unique clinical features and poor outcomes. Furthermore, our study strongly suggests that HBV-associated DLBCL might arise from HBV antigen-selected B cells. PMID:26314957

    The risk of mortality in patients with intracerebral hemorrhage (ICH) significantly increases when complicated by intraventricular hemorrhage (IVH). We hypothesize that serial measurement of cerebrospinal fluid (CSF) D-dimer levels in patients with both ICH and IVH may serve as an early marker of IVH severity. We performed a prospective study of 43 consecutive ICH patients combined with IVH and external ventricular drainage placement admitted in our institution from 2005-2006. IVH severity (Graeb score) and fibrinolytic activity were evaluated continuously for 7days using CT scans and CSF D-dimer levels. The primary outcome was 30day mortality. Overall 30day mortality was 26% (n=11), with eight deaths (72.7%) after 3days (D3). Graeb score and CSF D-dimer on admission (D0) were not significantly different between survivors and non-survivors. The temporal profiles of both parameters were distinctly different, with a downward trend in survivors and an upward trend in non-survivors. A mortality rate of 54% was observed between D0-D3 when both scores increased during this interval. In contrast, the mortality was only 4% when both measures decreased during this interval. Early phase (D0-D3) CSF D-dimer or Graeb score change demonstrated high sensitivity of 88% and specificity of 81% when predicting 30day mortality. Early phase CSF D-dimer change in patients with both ICH and IVH is accurate in predicting mortality and may be utilized as a cost-effective surrogate indicator of IVH severity. Serial monitoring of CSF D-dimer dynamic changes is useful for early identification of patients with hematoma progression and poor outcome. PMID:27050917

    Functional popliteal artery entrapment syndrome (PAES) is an important and possibly underrecognized cause of exertional leg pain (ELP). As it is poorly understood, it is at risk of misdiagnosis and mismanagement. The features indicative of PAES are outlined, as it can share features with other causes of ELP. Investigating functional PAES is also fraught with potential problems and if it is performed incorrectly, it can result in false negative and false positive findings. A review of the current vascular investigations is provided, highlighting some of the limitations standard tests have in determining functional PAES. Once a clinical suspicion for PAES is satisfied, it is necessary to further distinguish the subcategories of anatomical and functional entrapment and the group of asymptomatic occluders. When definitive entrapment is confirmed, it is important to identify the level of entrapment so that precise intervention can be performed. Treatment strategies for functional PAES are discussed, including the possibility of a new, less invasive intervention of guided Botulinum toxin injection at the level of entrapment as an alternative to vascular surgery.

    Purpose Constipation and incontinence are significant problems following pull-through surgery for Hirschsprung disease (HD). There is evidence that these problems improve with time. However, there is also evidence showing no improvements and furthermore, significant long-term data are lacking for the newer endorectal pull-through. We aim to determine if there is clinical evidence that show improvements in functional outcomes with time after an endorectal pull-through surgery for HD. Methods We utilized the validated pediatric incontinence and constipation scoring system (PICSS) to score 51 consecutive children 3 months to 15 years posttransabdominal or transanal endorectal pull-through for HD. Cases of total colonic aganglionosis and Down syndrome were excluded. PICSS scores below the age-specific lower limit 95% confidence interval scores represent incomplete continence or constipation, respectively. We performed linear regression to analyze the relationship between PICSS scores and the follow-up duration and then compared the demographics of children with and without incomplete continence and constipation, respectively. Significance was set at p < 0.05. Results The median age at PICSS interview was 71 months (range, 6-191 months). Incontinence scores obtained from 42 children older than 35 months showed a positive relationship with the follow-up duration (p = 0.03). Constipation scores obtained from 51 children were unrelated to follow-up duration (p = 0.486). When demographics were compared, the continent children had longer follow-up than those with incomplete continence (mean, 111.64 vs. 69.19 months; p = 0.051), however follow-up duration did not differ in the group of constipated children compared with the nonconstipated group (mean, 61.88 vs. 71.80 months; p = 0.321). Conclusion These findings suggest that after an endorectal pull-through, improved continence should be expected with time but constipation often continues to be an

    Background: Platinum-based pre-operative chemotherapy (POC) for muscle-invasive bladder cancer (MIBC) increases the complete pathological response rate at cystectomy and improves overall survival. However, 60% of MIBC patients still has muscle-invasive disease at cystectomy despite POC. Therefore, accurate prediction of response to POC is an important clinical need. We hypothesized that an elevated neutrophil-to-lymphocyte ratio (NLR) corresponds with adverse outcome in patients undergoing POC and radical cystectomy. Objective: To explore the correlation between the NLR and outcome in MIBC patients treated by POC and radical cystectomy. Methods: In 123 MIBC patients (urothelial carcinoma) who were treated by platinum-based POC and radical cystectomy, the derived NLR (dNLR) was retrospectively calculated by dividing the neutrophil count by the difference between leukocytes and neutrophil counts, prior to the start of chemotherapy. The correlation of the dNLR with pathological response at cystectomy and survival was analyzed by logistic regression analysis or the Kaplan-Meier method. Results: The complete pathological response (ypT0N0Mx) rate was 28.5%, 8.9% obtained a partial response (ypTa/T1/TisN0Mx), and 62.6% were non-responders (stage ≥ ypT2 and/or N+). An elevated dNLR (>2.21) correlated with non-response to POC (OR 2.70, 95% confidence interval: 1.15–6.38, p = 0.02) but this effect was nullified when corrected for clinically node-positive disease and clinical T stage. Patients with an elevated dNLR had shorter progression-free and overall survival albeit non-significant (p = 0.42, and p = 0.45, respectively). Conclusions: An elevated dNLR corresponded with poor outcome in terms of survival and non-response to POC in MIBC patients undergoing radical surgery. However, after correction for well-known prognostic factors, such as positive lymph node status at diagnostic imaging and clinical T stage, the correlation for the dNLR was nullified

    Metastatic capacities are fundamental features of tumor malignancy. ADP-ribosylation factor (ARF) 1 has emerged as a key regulator of invasion in breast cancer cells. However, the importance of this GTPase, in vivo, remains to be demonstrated. We report that ARF1 is highly expressed in breast tumors of the most aggressive and advanced subtypes. Furthermore, we show that lowered expression of ARF1 impairs growth of primary tumors and inhibits lung metastasis in a murine xenograft model. To understand how ARF1 contributes to invasiveness, we used a poorly invasive breast cancer cell line, MCF7 (ER+), and examined the effects of overexpressing ARF1 to levels similar to that found in invasive cell lines. We demonstrate that ARF1 overexpression leads to the epithelial-mesenchymal transition (EMT). Mechanistically, ARF1 controls cell–cell adhesion through ß-catenin and E-cadherin, oncogenic Ras activation and expression of EMT inducers. We further show that ARF1 overexpression enhances invasion, proliferation and resistance to a chemotherapeutic agent. In vivo, ARF1 overexpressing MCF7 cells are able to form more metastases to the lung. Overall, our findings demonstrate that ARF1 is a molecular switch for cancer progression and thus suggest that limiting the expression/activation of this GTPase could help improve outcome for breast cancer patients.

    Purpose: To evaluate early patency rate of the heparin-bonded stent grafts in atherosclerotic long femoropopliteal occlusive disease, and to identify factors that affect outcome. Methods: Heparin-bonded Viabahn stent grafts were placed in 33 limbs in 33 patients during 2009-2010. The stents were deployed to rescue failed conventional balloon angioplasty. Mean age was 69 (range 44-88) years, and 67 % (22 of 33) were men. Most procedures (21 of 33, 64 %) were performed for critical limb ischemia (33 % for rest pain, 30 % tissue loss). Kaplan-Meier plots and Cox regression analysis were used to identify significant risk factors. Results: The average length of lesions treated was 25 {+-} 10 cm, and they were predominantly TASC (Transatlantic Intersociety Consensus) D (n = 13) and C (n = 17) lesions. The median primary patency was 5.0 months (95 % confidence interval 1.22-8.77). The mean secondary patency was 8.6 months (95 % confidence interval 6.82-10.42). Subsequently, 4 patients underwent bypass surgery and 5 patients underwent major amputation. One patient died. There were 5 in-stent or edge-stent stenoses. Cox multivariate regression analysis identified TASC D lesions to be a significant risk factor for early occlusion (p = 0.035). Conclusion: TASC D lesions of femoropopliteal occlusions have poor patency rates with the use of heparin-bonded stent grafts after failed conventional angioplasty. Alternative options should be considered for these patients.

    The evidence linking obesity with ovarian cancer remains controversial. Leptin is expressed at higher levels in obese women and stimulates cell migration in other epithelial cancers. Here, we explored the clinical impact of overweight/obesity on patient prognosis and leptin's effects on the metastatic potential of ovarian cancer cells. We assessed clinical outcomes in 70 ovarian cancer patients (33 healthy weight and 37 overweight) that were validated with an external cohort from The Cancer Genome Atlas (TCGA) database. Progression-free and overall survival rates were significantly decreased in overweight patients. Similarly, a worse overall survival rate was found in TCGA patients expressing higher leptin/OB-Rb levels. We explored serum and ascites leptin levels and OB-Rb expression in our cohort. Serum and ascites leptin levels were higher in overweight patients experiencing worse survival. OB-Rb was more highly expressed in ascites and metastases than in primary tumors. Leptin exposure increased cancer cell migration/invasion through leptin-mediated activation of JAK/STAT3, PI3/AKT and RhoA/ROCK and promoted new lamellipodial, stress-fiber and focal adhesion formation. Leptin also contributed to the maintenance of stemness and the mesenchymal phenotype in ovarian cancer cells. Our findings demonstrate that leptin stimulated ovarian cancer cell migration and invasion, offering a potential explanation for the poor prognosis among obese women. PMID:26053184

    Metastatic capacities are fundamental features of tumor malignancy. ADP-ribosylation factor (ARF) 1 has emerged as a key regulator of invasion in breast cancer cells. However, the importance of this GTPase, in vivo, remains to be demonstrated. We report that ARF1 is highly expressed in breast tumors of the most aggressive and advanced subtypes. Furthermore, we show that lowered expression of ARF1 impairs growth of primary tumors and inhibits lung metastasis in a murine xenograft model. To understand how ARF1 contributes to invasiveness, we used a poorly invasive breast cancer cell line, MCF7 (ER+), and examined the effects of overexpressing ARF1 to levels similar to that found in invasive cell lines. We demonstrate that ARF1 overexpression leads to the epithelial-mesenchymal transition (EMT). Mechanistically, ARF1 controls cell-cell adhesion through ß-catenin and E-cadherin, oncogenic Ras activation and expression of EMT inducers. We further show that ARF1 overexpression enhances invasion, proliferation and resistance to a chemotherapeutic agent. In vivo, ARF1 overexpressing MCF7 cells are able to form more metastases to the lung. Overall, our findings demonstrate that ARF1 is a molecular switch for cancer progression and thus suggest that limiting the expression/activation of this GTPase could help improve outcome for breast cancer patients.

    The evidence linking obesity with ovarian cancer remains controversial. Leptin is expressed at higher levels in obese women and stimulates cell migration in other epithelial cancers. Here, we explored the clinical impact of overweight/obesity on patient prognosis and leptin's effects on the metastatic potential of ovarian cancer cells. We assessed clinical outcomes in 70 ovarian cancer patients (33 healthy weight and 37 overweight) that were validated with an external cohort from The Cancer Genome Atlas (TCGA) database. Progression-free and overall survival rates were significantly decreased in overweight patients. Similarly, a worse overall survival rate was found in TCGA patients expressing higher leptin/OB-Rb levels. We explored serum and ascites leptin levels and OB-Rb expression in our cohort. Serum and ascites leptin levels were higher in overweight patients experiencing worse survival. OB-Rb was more highly expressed in ascites and metastases than in primary tumors. Leptin exposure increased cancer cell migration/invasion through leptin-mediated activation of JAK/STAT3, PI3/AKT and RhoA/ROCK and promoted new lamellipodial, stress-fiber and focal adhesion formation. Leptin also contributed to the maintenance of stemness and the mesenchymal phenotype in ovarian cancer cells. Our findings demonstrate that leptin stimulated ovarian cancer cell migration and invasion, offering a potential explanation for the poor prognosis among obese women. PMID:26053184

    The purpose of this study was to identify the dysregulated genes involved in the tumorigenesis and progression of endometrial endometrioid adenocarcinoma (EEC), and their possible mechanisms. Endometrial specimens including normal endometrial tissues, atypical endometrial hyperplasia, and EEC were analyzed. The expression profiles were compared using GeneChip Array. The gene expression levels were determined by real-time RT-PCR in the training and testing sets to correlate the clinico-pathological parameters of EEC. Immunoblotting, in vitro cell migration and invasion assays were performed in human endometrial cancer cell lines and their transfectants. In microarray analysis, seven dysregulated genes were identified. Only the levels of urokinase-type plasminogen activator (uPA) were higher in EEC with deep myometrial invasion, positive lympho-vascular space invasion, lymph node metastasis, and advanced stages. After multivariate analysis, uPA was the only independent poor prognostic factor for disease-free survival in the EEC patients (hazard ratio: 4.65, p = 0.03). uPA may enhance the migratory and invasive capabilities of endometrial tumor cells by the phosphorylation of ERK1/2, Akt and p38 molecules. uPA is a dysregulated gene involved in the tumorigenesis, bio-pathological features and outcomes of EEC. uPA may be a potential molecule and target for the detection and treatment of EEC.

    The National Council on Compensation Insurance (NCCI) maintains a national data base of outcomes of workers` compensation claims. We consider whether a radial basis function network can predict the total dollar value of a claim based upon medical and demographic indicators (MDI`s). This work used data from 12,130 workers` compensation claims collected over a period of four years from the state of New Mexico. Two problems were addressed: (1) How well can the total incurred medical expense for all claims be predicted from available MDI`s? For individual claims? (2) How well can the duration of disability be predicted from available MDI`s? The available features intuitively correlated with total medical cost were selected, including type of injury, part of body injured, person`s age at time of injury, gender, marital status, etc. These features were statistically standardized and sorted by correlation with outcome valuation. Principal component analysis was applied. A radial basis function neural network was applied to the feature sets in both supervised and unsupervised training modes. For sets used in training, individual case valuations could consistently be predicted to within $1000 over 98% of the time. For these sets, it was possible to predict total medical expense for the training sets themselves to within 10%. When applied as blind tests against sets which were NOT part of the training data, the prediction was within 15% on the whole sets. Results on individual cases were very poor in only 30% of the cases were the predictions for the training sets within $1000 of their actual valuations. Single-factor analysis suggested that the presence of an attorney strongly decorrelated the data. A simple stratification was performed to remove cases involving attorneys and contested claims, and the procedures above repeated. Preliminary results based upon the very limited effort applied indicate that NCCI data support population estimates, but not single-point estimates.

    Background and Purpose Left ventricular (LV) diastolic dysfunction, developed in relation to myocardial dysfunction and remodeling, is documented in 15%-25% of the population. However, its role in functional recovery and recurrent vascular events after acute ischemic stroke has not been thoroughly investigated. Methods In this retrospective observational study, we identified 2,827 ischemic stroke cases with adequate echocardiographic evaluations to assess LV diastolic dysfunction within 1 month after the index stroke. The peak transmitral filling velocity/mean mitral annular velocity during early diastole (E/e’) was used to estimate LV diastolic dysfunction. We divided patients into 3 groups according to E/e’ as follows: <8, 8-15, and ≥15. Recurrent vascular events and functional recovery were prospectively collected at 3 months and 1 year. Results Among included patients, E/e’ was 10.6±6.4: E/e’ <8 in 993 (35%), 8-15 in 1,444 (51%), and ≥15 in 378 (13%) cases. Functional dependency or death (modified Rankin Scale score ≥2) and composite vascular events were documented in 1,298 (46%) and 187 (7%) patients, respectively, at 3 months. In multivariable analyses, ischemic stroke cases with E/e’ ≥15 had increased odds of functional dependence or death at 3 months (adjusted OR [95% CI]: 1.73 [1.27-2.35]) or 1 year (1.47 [1.06-2.06]) and vascular events within 1 year (1.65 [1.08-2.51]). Subgroups with normal ejection fraction or sinus rhythm exhibited a similar overall pattern and direction. Conclusions LV diastolic dysfunction was associated with poor functional outcomes and composite vascular events up to 1 year. PMID:27283279

    Recent accumulating genomic and proteomic data suggested that decreased expression of phenazine biosynthesis-like domain-containing protein (PBLD) was frequently involved in hepatocellular carcinoma (HCC). However, there is lack of systematical investigation focusing on its expression pattern, clinical relevance, and biological function. Here, we found that PBLD was frequently decreased in HCC tissues relative to adjacent non-tumorigenic liver tissues. This decreased expression was significantly associated with poor tumor differentiation and advanced tumor stage. Kaplan–Meier analysis further showed that recurrence-free survival and overall survival were significantly worse among patients with low PBLD expression. Moreover, multivariate analyses revealed that PBLD was an independent predictor of OS and RFS. This prognostic value of PBLD was further validated in another independent cohort. We also found PBLD inhibited HCC cell growth and invasion in vitro and tumor growth in vivo. Furthermore, forced expression of PBLD influenced multiple downstream genes related to MAPK, NF-κB, EMT, and angiogenesis signaling pathways. PBLD deletion was an independent predictor of poor prognosis in patients with HCC. Elevated PBLD expression may reduce HCC cell growth and invasion via inactivation of several tumorigenesis-related signaling pathways. PMID:26594798

    The overall objective of this study was to investigate reading comprehension in youth with and without a prior diagnosis of attention-deficit hyperactivity disorder (ADHD). The first goal was to determine whether youth with and without ADHD matched in word reading ability exhibited differences in reading comprehension proficiency. The next goal was to determine whether good and poor comprehenders within the ADHD subgroup differed from each other on language and academic achievement measures. The third objective was to examine whether word recognition or oral vocabulary knowledge mediated the effect of ADHD symptoms on reading comprehension performance. Youth with ADHD scored significantly lower than the comparison youth on a standardized measure of reading comprehension. Relative to good comprehenders with ADHD, poor comprehenders with ADHD exhibited weaknesses in expressive vocabulary, mathematical reasoning, written expression, and exhibited more executive function (EF) difficulties as reported by the teacher. Expressive vocabulary and word reading, but not teacher EF ratings, accounted for unique variance in reading comprehension performance and mediated the relationship between ADHD symptoms and reading comprehension. Implications for further research and educational practice are discussed. PMID:25589478

    Abstract Background Several studies assessed the association of prevalent fractures with muscle mass, strength, and physical capacity in men. Clinical impact of these associations is not clear, and they could be influenced by confounders. Our aim was to assess the association of the prevalent fractures with muscle strength, physical function, and the risk of subsequent falls in older men after adjustment for muscle mass and potential confounders. Methods In a cohort of 890 men aged 50 and older, we assessed appendicular skeletal muscle mass (ASM) by DXA, grip strength, physical function (chair stands, static, and dynamic balance). Relative ASM (RASM) was calculated as ASM / (height)2. Then, 813 men aged 60 and over were followed up prospectively for 5 years and 144 sustained >1 incident falls. All the analyses were adjusted for lifestyle factors, co‐morbidities, and hormones known to influence muscle and physical function. Results Low leisure physical activity, very high occupational physical activity, Parkinson's disease, diabetes mellitus, low apparent free testosterone concentration (AFTC), as well as Grade 2 and 3 vertebral fractures and multiple fractures were associated with lower grip strength when adjusted for confounders including upper limb RASM. Low leisure physical activity, very high occupational physical activity, diabetes mellitus, prior stroke, low AFTC and 25‐hydroxycholecalciferol, high C‐reactive protein, vertebral fractures, and non‐vertebral fractures were associated with poor physical function (lowest quintile of the score of tests) when adjusted for confounders including lower limb RASM. Grade 2 and 3 and multiple vertebral fractures were associated with twofold higher risk of multiple falls after adjustment for confounders. Men having multiple fractures had a twofold higher risk of multiple falls after adjusting for confounders. In multivariable models, risk of falls increased proportionally to the increasing severity and

    Frontalis suspension using autogenous fascia lata is a common procedure for blepharoptosis with poor levator function. However, donor-site morbidity associated with fascia lata harvest cannot be ignored. In conventional procedures, the required length of the fascia lata is usually >5-12 cm with a lateral thigh skin incision of approximately 5 cm or more. The present study introduces a new frontalis suspension procedure in which the required size (length and width) of the fascia lata and length of lateral thigh incision is much smaller. The harvested fascia lata is tailored to an inverted Y shape and the separated caudal legs are fixed to the tarsus while the cephalic end is grafted inside the eyebrow through a suborbital septum tunnel. In the present study, 11 patients who underwent the new procedure with a minimum of 6 months of follow-up were evaluated. The average length and width of the harvested fascia lata in unilateral ptosis cases were 2.85 and 0.89 cm, respectively. The average length of the lateral thigh incision was 1.25 cm. The margin reflex distance improved in all cases at 6 months postoperatively. The cosmetic result was graded as good to excellent in most of the patients. Trichiasis, widened donor scar, and eyebrow notch were noted as complications. The present method is a good alternative for the treatment of blepharoptosis with poor levator function. It potentially reduces donor-site morbidity as compared with conventional frontalis muscle suspension procedures using autogenous fascia lata. PMID:25260853

    Mutation of oncogene KRAS is common in non-small cell lung cancer (NSCLC), however, its clinical significance is still controversial. Independent studies evaluating its prognostic and predictive value usually drew inconsistent conclusions. Hence, We performed a meta-analysis with 41 relative publications, retrieved from multi-databases, to reconcile these controversial results and to give an overall impression of KRAS mutation in NSCLC. According to our findings, KRAS mutation was significantly associated with worse overall survival (OS) and disease-free survival (DFS) in early stage resected NSCLC (hazard ratio or HR=1.56 and 1.57, 95% CI 1.39-1.76 and 1.17-2.09 respectively), and with inferior outcomes of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) treatment and chemotherapy (relative risk or RR=0.21 and 0.66 for objective response rate or ORR, 95% CI 0.12-0.39 and 0.54-0.81 respectively; HR=1.46 and 1.30 for progression-free survival or PFS, 95%CI 1.23-1.74 and 1.14-1.50 respectively) in advanced NSCLC. When EGFR mutant patients were excluded, KRAS mutation was still significantly associated with worse OS and PFS of EGFR-TKIs (HR=1.40 and 1.35, 95 % CI 1.21-1.61 and 1.11-1.64). Although KRAS mutant patients presented worse DFS and PFS of chemotherapy (HR=1.33 and 1.11, 95% CI 0.97-1.84 and 0.95-1.30), and lower response rate to EGFR-TKIs or chemotherapy (RR=0.55 and 0.88, 95 % CI 0.27-1.11 and 0.76-1.02), statistical differences were not met. In conclusion, KRAS mutation is a weak, but valid predictor for poor prognosis and treatment outcomes in NSCLC. There's a need for developing target therapies for KRAS mutant lung cancer and other tumors. PMID:26840022

    Compound EGFR mutations, defined as double or multiple mutations in the EGFR tyrosine kinase domain, are frequently detected with advances in sequencing technology but its clinical significance is unclear. This study analyzed 61 cases of EGFR mutation positive lung adenocarcinoma using next-generation sequencing (NGS) based repeated deep sequencing panel of 16 genes that contain actionable mutations and investigated clinical implication of compound EGFR mutations. Compound EGFR mutation was detected in 15 (24.6%) of 61 cases of EGFR mutation-positive lung adenocarcinoma. The majority (12/15) of compound mutations are combination of the atypical mutation and typical mutations such as exon19 deletion, L858R or G719X substitutions, or exon 20 insertion whereas 3 were combinations of rare atypical mutations. The patients with compound mutation showed shorter overall survival than those with simple mutations (83.7 vs. 72.8 mo; P = 0.020, Breslow test). Among the 115 missense mutations discovered in the tested genes, a few number of actionable mutations were detected irrelevant to the subtype of EGFR mutations, including ALK rearrangement, BCL2L11 intron 2 deletion, KRAS c.35G>A, PIK3CA c.1633G>A which are possible target of crizotinib, BH3 mimetics, MEK inhibitors, and PI3K-tyrosine kinase inhibitors, respectively. 31 missense mutations were detected in the cases with simple mutations whereas 84 in those with compound mutation, showing that the cases with compound missense mutation have higher burden of missense mutations (P = 0.001, independent sample t-test). Compound EGFR mutations are detected at a high frequency using NGS-based repeated deep sequencing. Because patients with compound EGFR mutations showed poor clinical outcomes, they should be closely monitored during follow-up. PMID:26785607

    Purpose Cancer tissue may display a wide spectrum of expression phenotypes of epithelial-mesenchymal transition (EMT)-related proteins. The purpose of this study was to investigate the clinical significance of EMT phenotypes in breast cancer. Methods We evaluated the expression pattern of the EMT-related proteins E-cadherin and fibronectin in samples from 1,495 patients with invasive breast carcinoma (IBC) on tissue microarrays using immunohistochemistry to investigate the clinical significance of EMT phenotypes in IBC. EMT phenotypes were divided into complete type (E-cadherin-negative/fibronectin-positive), incomplete type (hybrid type, E-cadherinpositive/fibronectin-positive; null type, E-cadherin-negative/fibronectin-negative), and wild-type (E-cadherin-positive/fibronectin-negative). We analyzed the correlation of EMT phenotype with clinicopathological factors and patient survival. Results Loss of E-cadherin was observed in 302 patients (20.2%), and fibronectin was expressed in the cancer cells of 354 patients (23.7%). In total, 64 (4.3%), 290 (19.4%), 238 (15.9%), and 903 (60.4%) samples were categorized as complete, hybrid, null, and wild-type, respectively. The complete EMT phenotype exhibited significant associations with young age (p=0.017), advanced pT (p<0.001) and pN (p<0.001) stages, higher histological grade (p<0.001), lymphovascular invasion (p<0.001), and triple negativity (p<0.001). Patients with complete and hybrid EMT phenotypes had poorer overall survival (OS) and disease-free survival (DFS) than those with the wild-type phenotype (OS, p=0.001; DFS, p<0.001). In multivariate analysis, the hybrid EMT phenotype was an independent prognostic factor for DFS in patients with IBC (p=0.032). Conclusion EMT phenotypes exhibited significant associations with clinicopathological factors indicating aggressive biologic behavior and poor outcome in patients with IBC. PMID:26472976

    Purpose: To investigate the effect of hemoglobin (Hb) concentration and the difference in its decrease during treatment on outcome of radiotherapy (RT) alone for patients with Stage I and II nasopharyngeal carcinoma. Methods and Materials: A total of 572 patients with Stage I-II nasopharyngeal carcinoma with RT alone between January 2001 and December 2004 were retrospectively analyzed. Patient characteristics, tumor variables, and Hb level, including pre-RT Hb, mid-RT Hb, and dynamic change of Hb between pre- and post- RT and its difference in decrease ( White-Up-Pointing-Small-Triangle Hb) were subjected to univariate and multivariable analysis to identify factors that predict disease-specific survival (DSS), local regional recurrence-free survival (LRFS), and metastases-free survival (MFS). Results: The 5-year DSS was poorer in the Hb continuous decrease group than in the Hb noncontinuous decrease group (84% vs. 89%; p = 0.008). There was poorer 5-year DSS in patients with White-Up-Pointing-Small-Triangle Hb of >11.5 g/L than in those with White-Up-Pointing-Small-Triangle Hb of {<=}11.5 g/L (82% vs. 89%; p = 0.001), and poorer LRFS (79% vs. 83%; p = 0.035). Univariate and multivariate analysis showed that Hb decrease difference with greater than 11.5 g/L was an independent prognostic factor for DSS and LRFS. Conclusions: The difference in decrease of Hb level during the course of radiation treatment appeared as a poor prognostic factor in Stage I and II nasopharyngeal carcinoma patients.

    Purpose To evaluate the outcomes of 360-degree suture trabeculotomy in childhood glaucoma with poor prognosis. Subjects and Methods A nonrandomized, retrospective chart review was performed on pediatric patients (under 18 years old) treated with a 360-degree suture trabeculotomy for glaucoma. The cases were categorized into the following groups: (1) primary congenital glaucoma with birth-onset presentation accompanied by corneal clouding noted at birth, (2) primary congenital glaucoma with onset or presentation after 1 year of age, (3) primary congenital glaucoma with prior failed goniotomy surgery, (4) infantile-onset glaucoma following congenital cataract surgery, and (5) infantile-onset glaucoma with associated ocular/systemic anomalies. Results A total of 45 eyes of 33 patients were analyzed. The mean preoperative intraocular pressure (IOP) was 34.3 ± 6.7 mm Hg on an average of 1.5 medications. Median age at time of surgery was 7 months. Mean final IOP (median last follow-up or failure, 12 months) was 22.2 ± 7.1 mm Hg on an average of 1.5 medications. The probability of success according to time after surgery was 87% at 6 months, 63% at 1 year, and 58% at 2 years. Kaplan-Meier analysis of Groups 1-4 versus Group 5 failed to demonstrate a statistically significant difference (p = 0.13). Of 5 eyes with port wine mark–related glaucoma, 2 had a large (>50%), persistent postoperative hyphema and concurrent vitreous hemorrhage. Conclusions Children with a wide range of ocular pathologies can be successfully treated with 360-degree suture trabeculotomy. Further evaluation of this surgical technique in primary congenital glaucoma and open-angle glaucoma following congenital cataract surgery is warranted. PMID:21397807

  11. The importance of functional impairment to mental health outcomes: A case for reassessing our goals in depression treatment research

    2009-01-01

    Outcomes in depression treatment research include both changes in symptom severity and functional impairment. Symptom measures tend to be the standard outcome but we argue that there are benefits to considering functional outcomes. An exhaustive literature review shows that the relationship between symptoms and functioning remains unexpectedly weak and often bidirectional. Changes in functioning often lag symptom changes. As a result, functional outcomes might offer depression researchers more critical feedback and better guidance when studying depression treatment outcomes. The paper presents a case for the necessity of both functional and symptom outcomes in depression treatment research by addressing three aims–1) review the research relating symptoms and functioning, 2) provide a rationale for measuring both outcomes, and 3) discuss potential artifacts in measuring functional outcomes. The three aims are supported by an empirical review of the treatment outcome and epidemiological literatures. PMID:19269076

    Hematogenous metastases are rarely present at diagnosis of ovarian clear cell carcinoma (OCC). Instead dissemination of these tumors is characteristically via direct extension of the primary tumor into nearby organs and the spread of exfoliated tumor cells throughout the peritoneum, initially via the peritoneal fluid, and later via ascites that accumulates as a result of disruption of the lymphatic system. The molecular mechanisms orchestrating these processes are uncertain. In particular, the signaling pathways used by malignant cells to survive the stresses of anchorage-free growth in peritoneal fluid and ascites, and to colonize remote sites, are poorly defined. We demonstrate that the transmembrane glycoprotein CUB-domain-containing protein 1 (CDCP1) has important and inhibitable roles in these processes. In vitro assays indicate that CDCP1 mediates formation and survival of OCC spheroids, as well as cell migration and chemoresistance. Disruption of CDCP1 via silencing and antibody-mediated inhibition markedly reduce the ability of TOV21G OCC cells to form intraperitoneal tumors and induce accumulation of ascites in mice. Mechanistically our data suggest that CDCP1 effects are mediated via a novel mechanism of protein kinase B (Akt) activation. Immunohistochemical analysis also suggested that CDCP1 is functionally important in OCC, with its expression elevated in 90% of 198 OCC tumors and increased CDCP1 expression correlating with poor patient disease-free and overall survival. This analysis also showed that CDCP1 is largely restricted to the surface of malignant cells where it is accessible to therapeutic antibodies. Importantly, antibody-mediated blockade of CDCP1 in vivo significantly increased the anti-tumor efficacy of carboplatin, the chemotherapy most commonly used to treat OCC. In summary, our data indicate that CDCP1 is important in the progression of OCC and that targeting pathways mediated by this protein may be useful for the management of OCC

    This study was to investigate the association of psychological characteristics and functional dyspepsia treatment outcome. 109 patients who met the criteria for FD were enrolled. Eysenck Personality Questionnaire (EPQ), Symptom Checklist 90 (SCL90), and the Pittsburgh Sleep Quality Index (PSQI) were used to measure personality, psychological symptoms, and sleep quality in our patients. Leeds Dyspepsia Questionnaire (LDQ) was used to assess dyspeptic symptoms at baseline and after eight weeks of treatment. The LDQ scores change after therapy, and the degraded rate of LDQ was used to assess the prognosis of patients. Logistic regression model was used to assess the effect of the personality, psychological symptoms, and sleep quality on the prognosis of patients. Our result revealed that poor sleep quality (OR = 7.68, 95% CI 1.83-32.25) and bad marriage status (OR = 1.22, 95% CI 1.10-1.36) had the negative effect on the prognosis of FD, while extroversion in personality traits (OR = 0.86, 95% CI 0.76-0.96) had positive effect on the prognosis of FD. We should pay attention to the sleep quality, the personality, and the marriage status of FD patients; psychological intervention may have benefit in refractory FD. PMID:27547220

    The prognosis of oncology patients admitted to the intensive care unit (ICU) is considered poor. Our objective was to analyze the characteristics and predictive factors of death in the ICU and functional outcome following ICU treatment for neuro-oncology patients. A retrospective study was conducted on all patients with primary brain tumor admitted to our institutional ICU for medical indications. Predictive impact on the risk of death in the ICU was analyzed as well as the functional status was evaluated prior and following ICU discharge. Seventy-one patients were admitted to the ICU. ICU admission indications were refractory seizures (41 %) and septic shock (17 %). On admission, 16 % had multi-organ failure. Ventilation was necessary for 41 % and catecholamines for 13 %. Twenty-two percent of patients died in the ICU. By multivariate analysis, predictive factors associated with an increased risk of ICU death were: non-neurological cause of admission [p = 0.045; odds ratio (OR) 5.405], multiple organ failure (p = 0.021; OR 8.027), respiratory failure (p = 0.006; OR 9.615), and hemodynamic failure (p = 0.008; OR 10.111). In contrast, tumor type (p = 0.678) and disease control status (p = 0.380) were not associated with an increased risk of ICU death. Among the 35 evaluable patients, 77 % presented with a stable or improved Karnofsky performance status following ICU hospitalization compared with the ongoing status before discharge. In patients with primary brain tumor admitted to the ICU, predictive factors of death appear to be similar to those described in non-oncology patients. ICU hospitalization is generally not associated with a subsequent decrease in the functional status. PMID:26608523

    Introduction Low back pain affects every population and is one of world’s foremost debilitating conditions. Clinically significant sciatica due to lumbar disc prolapse occurs in 4-6% of population. Fenestration discectomy as a surgical procedure is less time consuming, with lesser blood loss, lesser post-operative complications and does not compromise with stability of spine when compared to laminectomy. Aim Present study was conducted to determine extent of functional recovery i.e. pain relief and return to work in patients with lumbar disc prolapse treated by fenestration technique. Materials and Methods From October 2010 to March 2012, 50 patients with signs and symptoms of prolapsed lumbar intervertebral disc who failed to respond to conservative treatment were operated for discectomy by fenestration technique and studied prospectively. Functional outcome was evaluated by ‘Back Pain Functional Score (BPFS)’ of Strafford et al., PROLO rating scale to determine preoperative functional and economical status and outcome at final follow up after 6 months. In order to identify physical signs from non organic signs Wadell’s score system was used. Result of surgery was evaluated with help of McNab’s criteria. Results In our study, according to Back Pain Functional Scale by Strafford et al., and PROLO scale, good results were found in 42 (84%) cases, fair result in 8 cases (16%) and none with poor results at follow up of six months. According to PROLO economical and functional scale, 84% cases were able to join their previous occupation at end of six months and 76% cases had complete pain relief. In our study, correlation of age and duration of symptoms to functional outcome was statistically significant (p=0.089 & p = 0.098+ respectively) showing more good results among patients with age less than 30 years and patients having duration of symptoms less than 6 months. Conclusion Functional outcome of fenestration technique in terms of return to work and

    Microenvironmental factors contribute to the immune dysfunction characterizing acute myeloid leukemia (AML). Indoleamine 2,3-dioxygenase 1 (IDO1) is an interferon (IFN)-γ-inducible enzyme that degrades tryptophan into kynurenine, which, in turn, inhibits effector T cells and promotes regulatory T-cell (Treg) differentiation. It is presently unknown whether childhood AML cells express IDO1 and whether IDO1 activity correlates with patient outcome. We investigated IDO1 expression and function in 37 children with newly diagnosed AML other than acute promyelocytic leukemia. Blast cells were cultured with exogenous IFN-γ for 24 hours, followed by the measurement of kynurenine production and tryptophan consumption. No constitutive expression of IDO1 protein was detected in blast cells from the 37 AML samples herein tested. Conversely, 19 out of 37 (51%) AML samples up-regulated functional IDO1 protein in response to IFN-γ. The inability to express IDO1 by the remaining 18 AML samples was not apparently due to a defective IFN-γ signaling circuitry, as suggested by the measurement of signal transducer and activator of transcription 3 (STAT3) phosphorylation. Co-immunoprecipitation assays indicated the occurrence of physical interactions between STAT3 and IDO1 in AML blasts. In line with this finding, STAT3 inhibitors abrogated IDO1 function in AML blasts. Interestingly, levels of IFN-γ were significantly higher in the bone marrow fluid of IDO-expressing compared with IDO-nonexpressing AMLs. In mixed tumor lymphocyte cultures (MTLC), IDO-expressing AML blasts blunted the ability of allogeneic naïve T cells to produce IFN-γ and promoted Treg differentiation. From a clinical perspective, the 8-year event-free survival was significantly worse in IDO-expressing children (16.4%, SE 9.8) as compared with IDO-nonexpressing ones (48.0%, SE 12.1; p=0.035). These data indicate that IDO1 expression by leukemia blasts negatively affects the prognosis of childhood AML. Moreover

    Use of larger diameter femoral heads has been popularised in total hip arthroplasty (THA). Recent studies have implicated larger femoral heads in early failure. We evaluated what effect the size of the femoral head had on the early functional outcome in order to determine the optimal head size for the maximal functional outcome. There were 726 patients who underwent elective THA and were divided into 3 groups according to head size then compared with respect to functional outcome scores and dislocation rates. This study failed to show that increasing the size of the femoral head significantly improved the functional outcome at 1 year after total hip arthroplasty but that the use of a 36 mm or greater femoral head did reduce the dislocation rate.

    The ID3 algorithm for inductive learning was tested using preclassified material for patients suspected to have a thyroid illness. Classification followed a rule-based expert system for the diagnosis of thyroid function. Thus, the knowledge to be learned was limited to the rules existing in the knowledge base of that expert system. The learning capability of the ID3 algorithm was tested with an unselected learning material (with some inherent missing data) and with a selected learning material (no missing data). The selected learning material was a subgroup which formed a part of the unselected learning material. When the number of learning cases was increased, the accuracy of the program improved. When the learning material was large enough, an increase in the learning material did not improve the results further. A better learning result was achieved with the selected learning material not including missing data as compared to unselected learning material. With this material we demonstrate a weakness in the ID3 algorithm: it can not find available information from good example cases if we add poor examples to the data. PMID:1551737

    Objective. The study aim was to characterize the time-course of recovery in impairments, activity limitations, participation restrictions, disability, and quality of life during the first year after cardiac arrest. Secondarily, the study described the associations between the instruments used to measure each of these domains. Methods. Measures of global disability (Cerebral Performance Category, CPC, Modified Rankin Scale, mRS), quality of life, activity limitations, participation restrictions, and affective and cognitive impairments were administered to 29 participants 1, 6, and 12 months after cardiac arrest. Results. Global measures of disability indicated recovery between one month and one year after cardiac arrest (mean CPC: 2.1 versus 1.69,  P < 0.05; mean mRS: 2.55 versus 1.83, P < 0.05). While global measures of disability were moderately associated with participation, they were poorly associated with other measures. The cohort endorsed depressive symptomatology throughout the year but did not have detectable cognitive impairment. Conclusions. Recovery from cardiac arrest is multifaceted and recovery continues for months depending upon the measures being used. Measures of global disability, reintegration into the community, and quality of life yield different information. Future clinical trials should include a combination of measures to yield the most complete representation of recovery after cardiac arrest. PMID:26421282

    Manganese (Mn) oxides are among the most reactive natural minerals and play an important role in elemental cycling in oceanic and terrestrial environments. A large portion of naturally-occurring Mn oxides tend to be poorly-crystalline and/or nanocrystalline, with not fully resolved crystal structures. In this study, the crystal structures of their synthetic analogs including acid birnessite (AcidBir), {delta}-MnO{sub 2}, polymeric MnO{sub 2} (PolyMnO{sub 2}) and a bacteriogenic Mn oxide (BioMnO{sub x}), have been revealed using atomic pair distribution function (PDF) analysis. Results unambiguously verify that these Mn oxides are layered materials. The best models that accurately allow simulation of pair distribution functions (PDFs) belong to the monoclinic C12/m1 space group with a disk-like shape. The single MnO{sub 6} layers in the average structures deviate significantly from hexagonal symmetry, in contrast to the results of previous studies based on X-ray diffraction analysis in reciprocal space. Manganese occupancies in MnO{sub 6} layers are estimated to be 0.936, 0.847, 0.930 and 0.935, for AcidBir, BioMnOx, {delta}-MnO{sub 2} and PolyMnO{sub 2}, respectively; however, occupancies of interlayer cations and water molecules cannot be accurately determined using the models in this study. The coherent scattering domains (CSDs) of PolyMnO{sub 2}, {delta}-MnO{sub 2} and BioMnO{sub x} are at the nanometer scale, comprising one to three MnO{sub 6} layers stacked with a high disorder in the crystallographic c-axis direction. Overall, the results of this study advance our understanding of the mineralogy of Mn oxide minerals in the environment.

    Lung cancer is the leading cause of cancer-related death worldwide. For early stages of the disease, lung resection surgery remains the best treatment with curative intent, but significant morbidity is associated, especially among patients with poor pulmonary function and cardiorespiratory fitness. In those cases, the implementation of a preoperative exercise-based intervention could optimize patient's functional status before surgery and improve postoperative outcomes and enhance recovery. The aim of this systematic review is to provide the current body of knowledge regarding the effectiveness of a preoperative exercise-based intervention on postoperative and functional outcomes in patients with lung cancer submitted to lung resection surgery. A systematic review of the literature using CINAHL, EMBASE, MEDLINE, Pubmed, PEDro and SCOPUS was undertaken in September 2015 yielding a total of 1656 references. Two independent reviewers performed the assessment of the potentially eligible records against the inclusion criteria and finally, 21 articles were included in the review. Articles were included if they examined the effects of an exercise-based intervention on at least one of the selected outcomes: pulmonary function, (functional) exercise capacity, health-related quality of life (HRQoL) and postoperative outcomes (length of stay and postoperative complications). Fourteen studies were further selected for a meta-analysis to quantify the mean effect of the intervention and generate 95% confidence intervals (CIs) using the Cochrane Review Manager 5.0.25. For two of the outcomes included (exercise capacity and HRQoL), studies showed large heterogeneity and thus, a meta-analysis was considered inappropriate. Pulmonary function (forced vital capacity and forced expiratory volume in 1 s) was significantly enhanced after the intervention [standardized mean difference (SMD) = 0.38; 95% CI 0.14, 0.63 and SMD = 0.27, 95% CI 0.11, 0.42, respectively].

    The mitogen-activated protein kinase (MAPK) interacting protein kinases 1 and 2 (Mnk1 and Mnk2) play important roles in controlling signals involved in mRNA translation. In addition to the MAPKs (p38 or Erk), multiple studies suggest that the Mnk kinases can be regulated by other known kinases such as Pak2 and/or other unidentified kinases by phosphorylation of residues distinct from the sites phosphorylated by the MAPKs. Several studies have established multiple Mnk protein targets, including PSF, heterogenous nuclear ribonucleoprotein A1, Sprouty 2 and have lead to the identification of distinct biological functions and substrate specificity for the Mnk kinases. In this review we discuss the pathways regulating the Mnk kinases, their known substrates as well as the functional consequences of engagement of pathways controlled by Mnk kinases. These kinases play an important role in mRNA translation via their regulation of eukaryotic initiation factor 4E (eIF4E) and their functions have important implications in tumor biology as well as the regulation of drug resistance to anti-oncogenic therapies. Other studies have identified a role for the Mnk kinases in cap-independent mRNA translation, suggesting that the Mnk kinases can exert important functional effects independently of the phosphorylation of eIF4E. The role of Mnk kinases in inflammation and inflammation-induced malignancies is also discussed. PMID:25225600

    Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social functional outcomes in patients after brain injury. Twelve patients with traumatic brain injury and 12 healthy controls were recruited in this study. We examined neurocognition with the Wechsler Adult Intelligence Scale-Revised China, and daily and social functional outcomes with the Activity of Daily Living Scale and Social Disability Screening Schedule, respectively. Mismatch negativity was analyzed from electroencephalogram recording. The results showed that mismatch negativity amplitudes decreased in patients with traumatic brain injury compared with healthy controls. Mismatch negativity amplitude was negatively correlated with measurements of neurocognition and positively correlated with functional outcomes in patients after traumatic brain injury. Further, the most significant positive correlations were found between mismatch negativity in the fronto-central region and measures of functional outcomes. The most significant positive correlations were also found between mismatch negativity at the FCz electrode and daily living function. Mismatch negativity amplitudes were extremely positively associated with Social Disability Screening Schedule scores at the Fz electrode in brain injury patients. These experimental findings suggest that mismatch negativity might efficiently reflect functional outcomes in patients after traumatic brain injury. PMID:26170824

    Purpose: Ependymoma is less commonly found in the supratentorial brain and has known clinical and molecular features that are unique. Our single-institution series provides valuable information about disease control for supratentorial ependymoma and the complications of supratentorial irradiation in children. Methods and Materials: A total of 50 children with newly diagnosed supratentorial ependymoma were treated with adjuvant radiation therapy (RT); conformal methods were used in 36 after 1996. The median age at RT was 6.5 years (range, 1-18.9 years). The entire group was characterized according to sex (girls 27), race (white 43), extent of resection (gross-total 46), and tumor grade (anaplastic 28). The conformal RT group was prospectively evaluated for neurologic, endocrine, and cognitive effects. Results: With a median follow-up time of 9.1 years from the start of RT for survivors (range, 0.2-23.2 years), the 10-year progression-free and overall survival were 73% + 7% and 76% + 6%, respectively. None of the evaluated factors was prognostic for disease control. Local and distant failures were evenly divided among the 16 patients who experienced progression. Eleven patients died of disease, and 1 of central nervous system necrosis. Seizure disorders were present in 17 patients, and 4 were considered to be clinically disabled. Clinically significant cognitive effects were limited to children with difficult-to-control seizures. The average values for intelligence quotient and academic achievement (reading, spelling, and math) were within the range of normal through 10 years of follow-up. Central hypothyroidism was the most commonly treated endocrinopathy. Conclusion: RT may be administered with acceptable risks for complications in children with supratentorial ependymoma. These results suggest that outcomes for these children are improving and that complications may be limited by use of focal irradiation methods.

    Objective Decompressive craniectomy (DC) in patients with malignant middle cerebral artery (MCA) infarction is known to decrease the mortality rate. However, the functional outcomes (communication and oral intake) of this procedure remain unclear. Most patients with malignant MCA infarction exhibit a loss of consciousness, which may be principally governed by the thalamus. We herein investigated the functional outcomes of DC at 90 days after the onset of malignant MCA infarction and their association with preoperative thalamus deformation, which can occur due to pressure and edema. Methods Twelve of 2,692 patients with acute cerebral infarction were diagnosed with malignant MCA infarction and underwent DC. We evaluated preoperative thalamus damage using brain computed tomography and its association with communication and oral intake abilities and the modified Rankin Scale (mRS) and Barthel index scores at 90 days after stroke onset. Results The mRS score at 90 days was 0-4 in five patients. Seven patients could communicate immediately after surgery, while five could do so by 90 days. Five patients were able to resume the oral intake of food at 90 days. All patients with preoperative thalamus deformation showed a poor recovery, while those with absent or slight preoperative thalamus deformation showed a good recovery. Conclusion Patients with preoperative thalamus deformation caused by pressure and edema show a poor oral intake and communication abilities after DC, suggesting that preoperative thalamus deformation is a predictor of poor functional outcomes after DC in patients with malignant MCA infarction.

    Background The present study was conducted to determine the quality and content of research on the functional outcomes and complications post-metal radial head arthroplasty (RHAP). Methods A comprehensive search of medical databases for studies reporting on functional outcomes of patients undergoing metallic RHAP was conducted. The Structured Effectiveness Quality Evaluation Scale (SEQES) was used to evaluate quality of the studies. Results We identified 21 Sackett’s Level IV studies reporting on 391 radial heads. The mean duration of follow-up was 47.2 months and the mean (SD) age of patients was 48.4 years (6.9 years). The male to female ratio was found to be 1.05 : 1 and the dominant arm was involved in 54% of patients. When functional outcomes achieved post-RHAP were compared with normative scores, the comparison suggested that RHAP has good to excellent functional outcomes in short- to mid-term follow-up. The weighted mean (SD) Mayo Elbow Performance Score was 85.8 (4.1) (95% confidence interval 85.3 to 86.3). Incidences of implant removal (3.06%) and revision (2.22%) were found to be low. Conclusions There is consistent low-quality evidence of positive functional outcomes following RHAP. The heterogeneity of type of implant, patient characteristics and outcome measures used, along with an inadequate reporting of study details, restrict any definitive conclusions being made.

    Background Activation of the Wnt signaling pathway is implicated in aberrant cellular proliferation in various cancers. In 40% of endometrioid ovarian cancers, constitutive activation of the pathway is due to oncogenic mutations in β-catenin or other inactivating mutations in key negative regulators. Secreted frizzled-related protein 4 (SFRP4) has been proposed to have inhibitory activity through binding and sequestering Wnt ligands. Methodology/Principal Findings We performed RT-qPCR and Western-blotting in primary cultures and ovarian cell lines for SFRP4 and its key downstream regulators activated β-catenin, β-catenin and GSK3β. SFRP4 was then examined by immunohistochemistry in a cohort of 721 patients and due to its proposed secretory function, in plasma, presenting the first ELISA for SFRP4. SFRP4 was most highly expressed in tubal epithelium and decreased with malignant transformation, both on RNA and on protein level, where it was even more profound in the membrane fraction (p<0.0001). SFRP4 was expressed on the protein level in all histotypes of ovarian cancer but was decreased from borderline tumors to cancers and with loss of cellular differentiation. Loss of membrane expression was an independent predictor of poor survival in ovarian cancer patients (p = 0.02 unadjusted; p = 0.089 adjusted), which increased the risk of a patient to die from this disease by the factor 1.8. Conclusions/Significance Our results support a role for SFRP4 as a tumor suppressor gene in ovarian cancers via inhibition of the Wnt signaling pathway. This has not only predictive implications but could also facilitate a therapeutic role using epigenetic targets. PMID:22363760

    This multicenter study examined prevalence of cognitive and academic delays in children following liver transplant (LT). One hundred and forty-four patients ages 5-7 and 2 years post-LT were recruited through the SPLIT consortium and administered the Wechsler Preschool and Primary Scale of Intelligence, 3rd Edition (WPPSI-III), the Bracken Basic Concept Scale, Revised (BBCS-R), and the Wide Range Achievement Test, 4th edition (WRAT-4). Parents and teachers completed the Behavior Rating Inventory of Executive Function (BRIEF). Participants performed significantly below test norms on intelligence quotient (IQ) and achievement measures (Mean WPPSI-III Full Scale IQ = 94.7 ± 13.5; WRAT-4 Reading = 92.7 ± 17.2; WRAT-4 Math = 93.1 ± 15.4; p < 0001). Twenty-six percent of patients (14% expected) had 'mild to moderate' IQ delays (Full Scale IQ = 71-85) and 4% (2% expected) had 'serious' delays (Full Scale IQ ≤ 70; p < 0.0001). Reading and/or math scores were weaker than IQ in 25%, suggesting learning disability, compared to 7% expected by CDC statistics (p < 0.0001). Executive deficits were noted on the BRIEF, especially by teacher report (Global Executive Composite = 58; p < 0.001). Results suggest a higher prevalence of cognitive and academic delays and learning problems in pediatric LT recipients compared to the normal population. PMID:21272236

    Purpose: Patients with cancer of unknown primary (CUP) account for about 10% of patients with metastatic spinal cord compression (MSCC). This study aims to define the appropriate radiation regimen for these patients. Methods and Materials: Data of 143 CUP patients irradiated for MSCC were retrospectively evaluated. Short-course radiotherapy (RT) (1x8 Gy, 5x4 Gy, n = 68) and long-course RT (10x3 Gy, 15x2.5 Gy, 20x2 Gy, n = 75) plus 8 further potential prognostic factors (age, gender, performance status, visceral metastases, other bone metastases, number of involved vertebrae, ambulatory status, time of developing motor deficits before RT) were compared for functional outcome and survival. Results: Improvement of motor function occurred in 10% of patients, no further progression of motor deficits in 57%, and deterioration in 33%. On multivariate analysis, functional outcome was positively associated with slower development of motor deficits (p < 0.001), absence of visceral metastases (p = 0.008) and other bone metastases (p = 0.027), and ambulatory status (p = 0.054), not with the radiation regimen (p = 0.74). Recurrence of MSCC in the irradiated region occurred in 7 patients after median 6 months. Median survival was 4 months. On multivariate analysis, better survival was significantly associated with absence of visceral metastases (p < 0.001), absence of other bone metastases (p = 0.005), ambulatory status (p = 0.001), and slower development of motor deficits (p = 0.030). Conclusions: For MSCC treatment in patients with CUP, no significant difference was observed between short-course and long-course RT regarding functional outcome and survival. Short-course RT appears preferable, at least for patients with a poor predicted survival, as it is more patient convenient and more cost-effective.

    The shared goal of all parties developing therapeutics against malignant gliomas is to positively impact the lives of people affected by these cancers. Clinical outcome assessment (COA) tools, including measures of patient-reported outcome, performance outcome, clinician-reported outcome, and observer-reported outcome, allow patient-focused assessments to complement traditional efficacy measures such as overall survival and radiographic endpoints. This review examines the properties of various COA measures used in malignant glioma clinical trials to date and cross references their content to the priority signs, symptoms, and functional limitations defined through a community survey conducted by the National Brain Tumor Society. The overarching goal of this initiative is to identify COA measures that are feasible and have appropriate psychometric properties for use in this patient population as well as highlight where further development is needed.

    Background Long-term functional outcomes of supracondylar elbow fractures (SCEF) have not been well documented in the literature. We retrospectively evaluated functional outcomes of pediatric SCEF using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Methods We retrospectively reviewed the outcomes of patients who presented to our tertiary care pediatric emergency department with SCEF between January 2005 and December 2009. We reviewed their charts to assess several clinical parameters, including age, sex, Gartland classification of SCEF, weight, comorbidities, treatment intervention, physiotherapy and the extremity involved. The DASH questionnaire was administered in 2012. We performed a multiple linear regression analysis to determine the significance of these clinical parameters as they related to the DASH score for functional outcome. Results We included 94 patients with SCEF in our review. Pediatric SCEF had good functional outcomes based on the DASH questionnaire (mean score 0.77 ± 2.10). We obtained the following DASH scores: 0.45 ± 2.20 for type I, 1.09 ± 1.70 for type II and 1.43 ± 2.40 for type III fractures. There was no statistical difference in functional outcome, regardless of sex (p = 0.07), age at injury (p = 0.96), fracture type (p = 0.14), weight (p = 0.59), right/left extremity (p = 0.26) or surgery (p = 0.52). Conclusion Our results demonstrate that good functional outcomes can be expected with pediatric SCEF based on the DASH questionnaire, regardless of age at injury, sex, weight, right/left extremity or surgical/nonsurgical intervention, provided satisfactory reduction is achieved and maintained.

    Deficits in social cognition are common after traumatic brain injury (TBI). However, little is known about how such deficits affect functional outcomes. The purpose of this study was to investigate the relationship between social cognition and functional outcomes in patients with TBI. We studied this relationship in 20 patients with TBI over the course of 1 year post-injury. Patients completed neurocognitive assessments and social cognition tasks. The social cognition tasks included an emotion-perception task and three theory of mind tasks: the Faux Pas test, Reading the Mind in the Eyes (Eyes) test, and the Moving-Shapes paradigm. The Craig Handicap Assessment and Reporting Technique was used to assess functional outcomes. Compared with our database of normal subjects, patients showed impairments in all social cognition tasks. Multiple regression analysis revealed that theory of mind ability as measured by the Eyes test was the best predictor of the cognitive aspects of functional outcomes. The findings of this pilot study suggest that the degree to which a patient can predict what others are thinking is an important measure that can estimate functional outcomes over 1 year following TBI.

    Outcome measures are becoming increasingly important in health care. Functional outcome measures are of particular importance for lower limb amputees since much of the rehabilitation process is concerned with increasing mobility and personal independence. The Scottish Physiotherapy Amputee Research Group (SPARG) has used three measures of functional outcome: the Barthel Index, Russek's classification and the Locomotor Index. The review reported here involves 938 patients having a primary amputation at the transtibial or transfemoral level between October 1992 and July 1997. Differences in function due to age and level of amputation are well known clinically and the measures were compared by looking at their ability to detect these differences. The Barthel Index lacked sensitivity because of ceiling effects and should not be considered as a suitable functional outcome measure for amputee patients. Russek's classification does detect significant differences but requires a large number of patients making it unsuitable for single hospital investigations. The Locomotor Index demonstrates significant differences due to age and amputation level despite fewer patients being assessed by this measure during the period covered by this paper. The range of the Locomotor Index can be extended to cover more active amputees by considering its 'advanced activities' subscale separately. The Locomotor Index is a promising measure and should be considered by rehabilitation teams looking for a valid, reliable and sensitive functional outcome measure for use with lower limb amputees.

    Purpose/Objective(s): This study evaluated the efficacy and toxicity of proton therapy for functional pituitary adenomas (FPAs). Methods and Materials: We analyzed 165 patients with FPAs who were treated at a single institution with proton therapy between 1992 and 2012 and had at least 6 months of follow-up. All but 3 patients underwent prior resection, and 14 received prior photon irradiation. Proton stereotactic radiosurgery was used for 92% of patients, with a median dose of 20 Gy(RBE). The remainder received fractionated stereotactic proton therapy. Time to biochemical complete response (CR, defined as ≥3 months of normal laboratory values with no medical treatment), local control, and adverse effects are reported. Results: With a median follow-up time of 4.3 years (range, 0.5-20.6 years) for 144 evaluable patients, the actuarial 3-year CR rate and the median time to CR were 54% and 32 months among 74 patients with Cushing disease (CD), 63% and 27 months among 8 patients with Nelson syndrome (NS), 26% and 62 months among 50 patients with acromegaly, and 22% and 60 months among 9 patients with prolactinomas, respectively. One of 3 patients with thyroid stimulating hormone—secreting tumors achieved CR. Actuarial time to CR was significantly shorter for corticotroph FPAs (CD/NS) compared with other subtypes (P=.001). At a median imaging follow-up time of 43 months, tumor control was 98% among 140 patients. The actuarial 3-year and 5-year rates of development of new hypopituitarism were 45% and 62%, and the median time to deficiency was 40 months. Larger radiosurgery target volume as a continuous variable was a significant predictor of hypopituitarism (adjusted hazard ratio 1.3, P=.004). Four patients had new-onset postradiosurgery seizures suspected to be related to generously defined target volumes. There were no radiation-induced tumors. Conclusions: Proton irradiation is an effective treatment for FPAs, and hypopituitarism remains the primary

    Synopsis High-density lipoproteins (HDL) remove cell cholesterol and protect from atherosclerosis. The major HDL protein is apolipoprotein A-I (apoA-I). Most plasma apoA-I circulates in lipoproteins, yet ~5% forms monomeric lipid-poor/free species. This metabolically active species is a primary cholesterol acceptor and is central to HDL biogenesis. Structural properties of lipid-poor apoA-I are unclear due to difficulties in isolating this transient species. We used thermal denaturation of human HDL to produce lipid-poor apoA-I. Analysis of the isolated lipid-poor fraction showed protein:lipid weight ratio 3:1, with apoA-I, phosphatidylcholine and cholesterol ester at approximate molar ratios of 1:8:1. Compared to lipid-free apoA-I, lipid-poor apoA-I showed slightly altered secondary structure and aromatic packing, reduced thermodynamic stability, lower self-associating propensity, increased adsorption to phospholipid surface, and comparable ability to remodel phospholipids and form reconstituted HDL. Lipid-poor apoA-I can be formed by heating of either plasma or reconstituted HDL. We propose the first structural model of lipid-poor apoA-I which corroborates its distinct biophysical properties and postulates the lipid-induced ordering of the labile C-terminal region. In summary, HDL heating produces folded functional monomolecular lipid-poor apoA-I that is distinct from lipid-free apoA-I. Increased adsorption to phospholipid surface and reduced C-terminal disorder may help direct lipid-poor apoA-I towards HDL biogenesis. PMID:22150513

    cholesterol levels are still inversely related to MCVE. The efflux capacity, or ability to relocate cholesterol out of macrophages, is believed to be a major antiatherogenic mechanism responsible for reduction in MCVE mediated in part by healthy HDL. HDL cholesterol is a complex molecule with antioxidative, anti-inflammatory, anti-thrombotic, antiplatelet, and vasodilatory properties, among which is protection of LDL from oxidation. HDL-associated paraoxonase-1 has a major effect on endothelial function. Further, HDL promotes endothelial repair and progenitor cell health, and supports production of nitric oxide. HDL from patients with cardiovascular disease, diabetes, and autoimmune disease may fail to protect or even become proinflammatory or pro-oxidant. Mendelian randomization and other clinical studies in which raising HDL cholesterol has not been beneficial suggest that high plasma levels do not necessarily reduce cardiovascular risk. These data, coupled with extensive preclinical information about the functional heterogeneity of HDL, challenge the “HDL hypothesis”, ie, raising HDL cholesterol per se will reduce MCVE. After the equivocal AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome With Low HDL/High Triglycerides: Impact on Global Health Outcomes) study and withdrawal of two major cholesteryl ester transfer protein compounds, one for off-target adverse effects and the other for lack of efficacy, development continues for two other agents, ie, anacetrapib and evacetrapib, both of which lower LDL cholesterol substantially. The negative but controversial HPS2-THRIVE (the Heart Protection Study 2-Treatment of HDL to Reduce the Incidence of Vascular Events) trial casts further doubt on the HDL cholesterol hypothesis. The growing impression that HDL functionality, rather than abundance, is clinically important is supported by experimental evidence highlighting the conditional pleiotropic actions of HDL. Non-HDL cholesterol reflects the cholesterol in all

    Intracerebral hemorrhage (ICH) is a stroke subtype associated with high mortality and morbidity. Following ICH, excitotoxicity and inflammation significantly contribute to secondary brain injury and poor outcomes. Prostaglandin E2 (PGE2) levels rise locally with insult to the nervous system, and PGE2 is known to modulate these processes mainly through its E prostanoid (EP) receptors, EP1–4. EP3 is the most abundant EP receptor in the brain and we have previously shown that signaling through the PGE2-EP3 axis exacerbates excitotoxicity and ischemic stroke outcomes. This study aimed to investigate the contribution of this pathway in modulating anatomical outcomes and functional recovery following ICH. Genetic deletion of the EP3 receptor resulted in 48.2 ± 7.3% less ICH-induced brain injury (p < 0.005) and improved functional recovery (p < 0.05), as identified by neurological deficit scoring. To start investigating the mechanisms involved in neuroprotection with impaired PGE2-EP3 signaling, histological staining was performed to evaluate blood and ferric iron accumulation, neuroinflammation, blood brain barrier dysfunction, and peripheral neutrophil infiltration. After ICH, EP3−/− mice demonstrated 49.5 ± 8.8% and 42.8 ± 13.1% less blood (p < 0.01) and ferric iron content (p < 0.05), respectively. Furthermore, EP3−/− mice had significantly reduced astrogliosis, microglial activation, blood brain barrier breakdown, and neutrophil infiltration. Collectively, these results suggest an injurious role for the PGE2-EP3 signaling axis in modulating brain injury, inflammation, and neurologic functional recovery after ICH. Modulation of the PGE2-EP3 signaling axis may represent a putative therapeutic avenue for the treatment of ICH. PMID:25847406

    Objective: The goal of the Response Evaluation in Neurofibromatosis and Schwannomatosis Visual Outcomes Committee is to define the best functional outcome measures for future neurofibromatosis type 1 (NF1)-associated optic pathway glioma (OPG) clinical trials. Methods: The committee considered the components of vision, other ophthalmologic parameters affected by OPG, potential biomarkers of visual function, and quality of life measures to arrive at consensus-based, evidence-driven recommendations for objective and measurable functional endpoints for OPG trials. Results: Visual acuity (VA) assessments using consistent quantitative testing methods are recommended as the main functional outcome measure for NF1-OPG clinical trials. Teller acuity cards are recommended for use as the primary VA endpoint, and HOTV as a secondary endpoint once subjects are old enough to complete it. The optic disc should be assessed for pallor, as this appears to be a contributory variable that may affect the interpretation of VA change over time. Given the importance of capturing patient-reported outcomes in clinical trials, evaluating visual quality of life using the Children's Visual Function Questionnaire as a secondary endpoint is also proposed. Conclusions: The use of these key functional endpoints will be essential for evaluating the efficacy of future OPG clinical trials. PMID:24249802

    Patients with severe mental illnesses (SMI) often experience dysfunction in their ability to efficiently carry out everyday roles and/or skills. These deficits are seen across many domains of daily functioning. We suggest that the “self-conscious emotions” of pride and shame play a role in these functional outcomes. Pride and shame appear to facilitate individuals’ ability to evaluate their group status, detect social threats, and to adjust their behaviors accordingly. This study utilized an objective performance measure of functional capacity and a self-report of quality of life (QoL) to examine the respective roles of pride and shame in functional outcomes within two SMI patient groups (schizophrenia and affective disorder) and a community control group. The influence of neurocognition, affect and symptomatology on functional outcomes was also assessed. The patient groups did not differ in cognitive functioning, QoL, or shame. The schizophrenia group reported significantly higher pride and displayed worse objective performance than the other groups. Within each of the groups, shame had an inverse relationship with QoL, while pride positively associated with QoL. Shame associated with worse functional capacity in the schizophrenia group. Shame associated with better functional capacity, while pride associated with worse functional capacity within the affective disorder group. PMID:24508025

    Objectives To compare 6 month and 12 month health status and functional outcomes between regional major trauma registries in Hong Kong and Victoria, Australia. Summary Background Data Multicentres from trauma registries in Hong Kong and the Victorian State Trauma Registry (VSTR). Methods Multicentre, prospective cohort study. Major trauma patients and aged ≥18 years were included. The main outcome measures were Extended Glasgow Outcome Scale (GOSE) functional outcome and risk-adjusted Short-Form 12 (SF-12) health status at 6 and 12 months after injury. Results 261 cases from Hong Kong and 1955 cases from VSTR were included. Adjusting for age, sex, ISS, comorbid status, injury mechanism and GCS group, the odds of a better functional outcome for Hong Kong patients relative to Victorian patients at six months was 0.88 (95% CI: 0.66, 1.17), and at 12 months was 0.83 (95% CI: 0.60, 1.12). Adjusting for age, gender, ISS, GCS, injury mechanism and comorbid status, Hong Kong patients demonstrated comparable mean PCS-12 scores at 6-months (adjusted mean difference: 1.2, 95% CI: −1.2, 3.6) and 12-months (adjusted mean difference: −0.4, 95% CI: −3.2, 2.4) compared to Victorian patients. Keeping age, gender, ISS, GCS, injury mechanism and comorbid status, there was no difference in the MCS-12 scores of Hong Kong patients compared to Victorian patients at 6-months (adjusted mean difference: 0.4, 95% CI: −2.1, 2.8) or 12-months (adjusted mean difference: 1.8, 95% CI: −0.8, 4.5). Conclusion The unadjusted analyses showed better outcomes for Victorian cases compared to Hong Kong but after adjusting for key confounders, there was no difference in 6-month or 12-month functional outcomes between the jurisdictions.

    Prospective outcome studies are generally considered to be better than retrospective studies. The purpose of this study was to assess correlations between prospective and retrospective outcome assessment after rotator cuff repair. One-hundred and twelve patients (118 shoulders) with chronic rotator cuff tears were evaluated at a mean of 54 months (34-85) after rotator cuff repair, using several outcome measures including a retrospective assessment of improvement. The retrospective assessment of post-operative pain, function, and quality of life had fair correlations with the prospectively determined improvement (R = .23-.25, P < .01). Post-operative patient satisfaction was more highly correlated with all retrospective evaluations than with the prospective improvement in all functional outcome measures. Retrospective and prospective evaluations of the outcome of rotator cuff repair are different. Patient satisfaction has a greater correlation with retrospective outcomes. Retrospective evaluation may aid in supplementing prospective evaluations, as it may better reflect a patient's perception of the success after surgery. PMID:18693118

    Cerebral autoregulation (CA) is the mechanism that aims to maintain adequate cerebral perfusion during changes in blood pressure (BP). Transfer function analysis (TFA), the most reported method in literature to quantify CA, shows large between-study variability in outcomes. The aim of this study is to investigate the role of measurement artifacts in this variation. Specifically, the role of distortion in the BP and/or CBFV measurementon TFA outcomes was investigated. The influence of three types of artifacts on TFA outcomes was studied: loss of signal, motion artifacts, and baseline drifts. TFA metrics of signals without the simulated artifacts were compared with those of signals with artifacts. TFA outcomes scattered highly when more than 10% of BP signal or over 8% of the CBFV signal was lost, or when measurements contained one or more artifacts resulting from head movement. Furthermore, baseline drift affected interpretation of TFA outcomes when the power in the BP signal was 5 times the power in the LF band. In conclusion, loss of signal in BP and loss in CBFV, affects interpretation of TFA outcomes. Therefore, it is vital to validate signal quality to the defined standards before interpreting TFA outcomes. PMID:26935320

    Although typical functional analyses often produce clear outcomes, some studies have reported ambiguous results that cannot be interpreted. Such undifferentiated outcomes may occur if test conditions do not include relevant antecedent or consequent events. Clinicians then may try to modify the functional analysis conditions to include those events. Hanley, Iwata, and McCord (2003) reviewed the functional analysis literature through the year 2000 and described idiosyncratic variables included in modified functional analyses. The objective of the present review was to present a quantitative analysis of idiosyncratic antecedents and consequences in modified functional analyses during the past decade (2001 to 2010). We discuss the range of stimulus parameters tested and the assessment strategies used for informing the modified analysis conditions. PMID:24114110

    In 161 consecutive gamete intrafallopian transfer (GIFT) cycles in which supernumerary oocytes were inseminated, a failure to fertilize any of these oocytes was no more predictive of an unsuccessful outcome than the simple overall pregnancy rate in this group. This is possibly related to the significantly reduced proportion of oocytes graded as good in the supernumerary group. PMID:3230348

    Negative symptoms, in particular motivational deficits, are reported as impediments to functional recovery in patients with schizophrenia. This study examined the prevalence of motivational deficits in patients early in the illness, and the impact these deficits have on community functioning. Patients with schizophrenia between the ages of 18 and 35years, and within 5years of initiating antipsychotic treatment were included in the present investigation (N=166). The impact of motivation and cognition on concurrent and longitudinal functioning was evaluated. Motivational impairments were found in more than 75% of participants, and were not associated with receipt of social support. These deficits served as the most robust and reliable predictor of functional outcome, while neurocognition demonstrated significantly weaker associations with outcome. When considered together, motivational deficits demonstrated a reliable link with concurrent and longitudinal functioning, with cognition not offering any independent predictive value. Moreover, motivation was found to mediate the relationship between cognition and outcome. Changes in motivation were linked to changes in functioning; however, this was not the case for changes in cognitive performance. Motivation emerged as a significant predictor of functioning even after selected demographic and clinical characteristics (e.g., positive symptoms) were accounted for. These data indicate that motivational deficits are prevalent in patients with schizophrenia, even in the early stages of the illness, and these deficits stand as one of the most robust barriers to people with schizophrenia achieving functional recovery. Greater understanding of the mechanisms underlying these deficits is critical to effective treatment innovation. PMID:25982811

    Abstract Predictors of functional outcomes in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing pulmonary thromboendarterectomy (PTE) are important to identify preoperatively. We hypothesized that baseline severity of pulmonary hypertension and obesity would not be associated with 6-month functional outcomes after PTE. Clinical and hemodynamic data were collected on consecutive patients undergoing PTE from 2008 to 2014. Patients were stratified according to baseline pulmonary vascular resistance (PVR) and body mass index (BMI). Six-minute walk distance (6MWD), New York Heart Association functional class (FC), and echocardiography were assessed in each group at baseline and 6 months after PTE. Regression analyses were performed to evaluate for associations between functional outcomes and baseline PVR and BMI. Forty-two patients underwent PTE and had 6-month follow up data. In comparisons of patients with high and low baseline PVR, the baseline characteristics, distribution of disease, 6MWD, and FC were similar. Postoperative hemodynamics for both groups were similar. At 6 months, both groups achieved improvements in FC, and there were no between-group differences in the change in 6MWD or FC. In comparisons of obese and nonobese patients, perioperative and FC improvement were similar; however, obese patients achieved a greater improvement in 6MWD than nonobese patients (P = 0.04). In conclusion, our data suggest that baseline severity of CTEPH and obesity were not associated with worse functional outcome. Further studies are needed to confirm these results, as these findings could have implications for patient selection for PTE. PMID:27252843

    Objective We examined the association between physical activity recorded by Actigraphy during therapy sessions (therapy) to therapist rated patient participation and self reported future functional outcomes. We hypothesized those participants who were more active during rehab would have higher participation scores and better functional outcomes following hip fracture compared to those who were less active. Design Longitudinal study with 3 and 6 month follow-up. Setting Participants were recruited from skilled nursing (SN) and inpatient rehabilitation (IR) facilities. Participants Participants included 18 community dwelling older adults admitted to SN or IR facilities after hip fracture. Participants were included if they were ≥ 60 years of age and ambulatory with or without assistance from a device or another person. Intervention Not Applicable Main Outcome Measure Physical activity was quantified during participants’ rehab using the Actigraph accelerometer worn consecutively over 5 days. The Pittsburgh Participation Rating Scale was used to quantify patient participation during their inpatient therapy sessions. Self reported functional outcomes were measured by the Hip Fracture Functional Recovery Scale (HFRS) at baseline, 3 and 6 months following fracture. Results Participants with higher Actigraphy counts during rehab were ranked by their therapists as having excellent participation compared to those who were less active. Participants who were more active reported better functional abilities at both 3 and 6 month time points and achieved 78% and 91% recovery of self reported pre-fracture function compared to those who were less active achieving 64% and 73% recovery. Conclusion Actigraphy provides an objective measure of physical activity exhibiting predictive validity for future functional outcomes and concurrent validity against patient participation in patients after hip fracture.

    Epigenetic mechanisms, often defined as regulating gene activity independently of underlying DNA sequence, are crucial for healthy development. The sum total of epigenetic marks within a cell or tissue (the epigenome) is sensitive to environmental influence, and disruption of the epigenome in utero has been associated with adverse pregnancy outcomes. Not surprisingly, given its multifaceted functions and important role in regulating pregnancy outcome, the placenta shows unique epigenetic features. Interestingly however, many of these are only otherwise seen in human malignancy (the pseudomalignant placental epigenome). Epigenetic variation in the placenta is now emerging as a candidate mediator of environmental influence on placental functioning and a key regulator of pregnancy outcome. However, replication of findings is generally lacking, most likely due to small sample sizes and a lack of standardization of analytical approaches. Defining DNA methylation "signatures" in the placenta associated with maternal and fetal outcomes offers tremendous potential to improve pregnancy outcomes, but care must be taken in interpretation of findings. Future placental epigenetic research would do well to address the issues present in epigenetic epidemiology more generally, including careful consideration of sample size, potentially confounding factors, issues of tissue heterogeneity, reverse causation, and the role of genetics in modulating epigenetic profile. The importance of animal or in vitro models in establishing a functional role of epigenetic variation identified in human beings, which is key to establishing causation, should not be underestimated.

    A retrospective multi-centre study was carried out in order to compare outcomes between cemented and uncemented total hip arthoplasties (THA). A quantitative orthopaedic outcome assessment scoring system was devised in order to relate functional outcome to a numerical score, to allow comparison between treatments and amongst centres. The system combined a radiographic score and a clinical score. Lower scores reflect better outcomes than higher scores. Consecutive cases of THA were included from two specialist practices between July 2002 and December 2005. The study included 46 THA patients (22 uncemented THA followed for 8.3 +/- 4.7M and 24 cemented THA for 26.0 +/- 15.7M) with a mean age of 4.4 +/- 3.3 years at surgery. Multi-variable linear and logistical regression analyses were performed with adjustments for age at surgery, surgeon, follow-up time, uni- versus bilateral disease, gender and body weight. The differences between treatment groups in terms of functional scores or total scores were not significant (p > 0.05). Radiographic scores were different between treatment groups. However, these scores were usually assessed within two months of surgery and proved unreliable predictors of functional outcome (p > 0.05). The findings reflect relatively short-term follow-up, especially for the uncemented group, and do not include clinician-derived measures, such as goniometry and thigh circumference. Longer-term follow-up for the radiographic assessments is essential. A prospective study including the clinician-derived outcomes needs to be performed in order to validate the outcome instrument in its modified form. PMID:18536848

    Introduction: We present the functional outcomes of microvascular toe transfer to reconstruct the post-traumatic metacarpal hand deformity. Twelve toe transfers were successfully carried out in 11 patients. Materials and Methods: In each patient, the level of injury was classified according to the Wei classification system. Functional outcome was measured in seven patients using the Tamai score. Additional objective tests of function were carried out in three patients, including the Jebsen test, grip strength, pinch strength, web opening, static and moving two-point discrimination and Semmes–Weinstein monofilament testing. Observation and Results: The average Tamai score was 69 (range 60–83.5). Six patients achieved ‘good’ outcomes and one patient, with a double toe transfer, an ‘excellent’ outcome. The average follow-up time was 43 months (range 10–148 months). Conclusion: This study shows how even a single toe transfer can restore useful function to a hand that has otherwise lost all prehensile ability. PMID:27274118

    Although the overall mortality of patients admitted to intensive care units (ICU) with hematological malignancy has decreased over the years, some groups of patients still have low survival rates. We performed a monocentric retrospective study including all patients with hematological malignancy in a ten-year period, to identify factors related to the outcome for the whole cohort and for patients with allogeneic hematopoietic stem cell transplantation (HSCT), neutropenia, or those requiring invasive mechanical ventilation (IMV). A total of 418 patients with acute leukemia (n=239; 57%), myeloma (n=69; 17%), and lymphoma (n=53; 13%) were studied. Day-28 and 1-year mortality were 49% and 72%, respectively. The type of disease was not associated with outcome. The disease status was independentlty associated with 1-year mortality only. Independent predictors of day-28 mortality were IMV, renal replacement therapy (RRT), and performance status. For allogeneic HSCT recipients (n=116), neutropenic patients (n=124) and patients requiring IMV (n=196), day-28 and 1-year mortality were 52%, 54%, 74% and 81%, 78%, 87%, respectively. Multivariate analysis showed that IMV and RRT for allogeneic HSCT recipients, performance status and IMV for neutropenic patients, and RRT for patients requiring IMV were independently associated with short-term mortality (p<0.05). These results suggest that IMV is the strongest predictor of mortality in hematological patients admitted to ICUs, whereas allogeneic HSCT and neutropenia do not worsen their short-term outcome.

    ABSTRACT Heterotopic ossification is the formation of the lamellar bone where normally osseous tissue does not exist. Since heterotopic ossification can cause severe functional loss, it is a challenging condition for both clinicians and patients. Neurogenic heterotopic ossification is a rare condition after encephalitis. Likewise, in this paper, we have presented a challenging case of heterotopic ossification after viral encephalitis and functional outcomes after the management of heterotopic ossification.

    Background Both abnormal microvolt T-wave alternans (MTWA) and low peak VO2 predict poor outcome in heart failure. However, their independent predictive properties have not been assessed in large scale cohorts. Methods We performed an observational prospective cohort study of 303 consecutive patients referred for metabolic stress testing. All had an ejection fraction fl40% and were considered candidates for transplantation. Patients with defibrillators did not have MTWA collected by our exercise laboratory and therefore were not included in the analysis. The primary endpoint was a composite of all-cause death or UNOS 1 transplantation. Results During 2.8 years there were 34 deaths and 17 transplantations. Patients with abnormal MTWA had a higher event rate (31/136, 23%, vs. 20/167, 12%, unadjusted HR 1.90, 95% CI 1.90-3.33, P=.03). The association remained significant after adjustment for 3 clinical variables (1.89, 95% CI 1.05-3.39, P=.03). After adding peak VO2 to the model the association was no longer significant (adjusted HR 1.18, 95% CI 0.64-2.17, p=.60). After accounting for peak VO2 and 28 other confounders in a matched propensity analysis, MTWA was not predictive (propensity-matched HR 0.79, 95% CI 0.37-1.66, P=.53). Conclusions We confirm the association of abnormal MTWA with poor outcome amongst patients with impaired left ventricular systolic function. However, this association is markedly attenuated after accounting for peak VO2. PMID:19560697

    Introduction High energy intra-articular fractures involving the tibial plateau causes various problems related to management like wound dehiscence, severe comminution leading to malalignment and delayed complications like varus collapse, implant failure and arthritis of knee joint. Aim This study was done to determine functional, radiological outcome and the complications of Schatzker V and VI tibial plateau fractures treated with bipillar plating with dual plates with a regular follow-up of atleast 3 years. Materials and Methods Total 34 cases of tibial plateau fracture type V and VI treated with dual plating were studied from January 2011 to December 2013 in KIMS Hospital were followed for minimum of 3 years. The patients were operated through an anterolateral approach for lateral plate and a medial column plate was put through a minimally invasive medial approach or an open posteromedial approach. Results Total 34 patients were evaluated postoperatively thoroughly for functional outcome using The Knee Society Score and radiological outcomes by Modified Rasmussen Assessment criteria which showed 29 patients (85.29%) had excellent and 5 patients (14.71%) had good objective knee society score. 24 patients (70.59%) had excellent, 8 patients (23.53%) had good and 1patient (2.94%) were each of poor and fair functional knee society score. Eleven patients (32.35%) had excellent, 21patients (61.76%) had good and 2 patients (5.88%) had fair radiological outcome. Conclusion We conclude that open reduction and internal fixation of high-energy tibial plateau fractures with dual plates via 2 incisions gives excellent to good functional outcome with minimal soft tissue complications. Thus, a minimally invasive approach should be used which helps in preventing soft tissue problems and helps in early wound healing. Fixation done by bipillar plating is important for early mobilization of knee joint. Early mobilization leads to better range of movements and thereby better

    Background The risk to develop colorectal and endometrial cancers among subjects testing positive for a pathogenic Lynch syndrome mutation varies, making the risk prediction difficult. Genetic risk modifiers alter the risk conferred by inherited Lynch syndrome mutations, and their identification can improve genetic counseling. We aimed at identifying rare genetic modifiers of the risk of Lynch syndrome endometrial cancer. Methods A family based approach was used to assess the presence of genetic risk modifiers among 35 Lynch syndrome mutation carriers having either a poor clinical phenotype (early age of endometrial cancer diagnosis or multiple cancers) or a neutral clinical phenotype. Putative genetic risk modifiers were identified by Next Generation Sequencing among a panel of 154 genes involved in endometrial physiology and carcinogenesis. Results A simple pipeline, based on an allele frequency lower than 0.001 and on predicted non-conservative amino-acid substitutions returned 54 variants that were considered putative risk modifiers. The presence of two or more risk modifying variants in women carrying a pathogenic Lynch syndrome mutation was associated with a poor clinical phenotype. Conclusion A gene-panel is proposed that comprehends genes that can carry variants with putative modifying effects on the risk of Lynch syndrome endometrial cancer. Validation in further studies is warranted before considering the possible use of this tool in genetic counseling. PMID:26517685

    Background During the first wave of pandemic H1N1 influenza in 2009, most cases outside North America occurred in the UK. The clinical characteristics of UK patients hospitalised with pandemic H1N1 infection and risk factors for severe outcome are described. Methods A case note-based investigation was performed of patients admitted with confirmed pandemic H1N1 infection. Results From 27 April to 30 September 2009, 631 cases from 55 hospitals were investigated. 13% were admitted to a high dependency or intensive care unit and 5% died; 36% were aged <16 years and 5% were aged ≥65 years. Non-white and pregnant patients were over-represented. 45% of patients had at least one underlying condition, mainly asthma, and 13% received antiviral drugs before admission. Of 349 with documented chest x-rays on admission, 29% had evidence of pneumonia, but bacterial co-infection was uncommon. Multivariate analyses showed that physician-recorded obesity on admission and pulmonary conditions other than asthma or chronic obstructive pulmonary disease (COPD) were associated with a severe outcome, as were radiologically-confirmed pneumonia and a raised C-reactive protein (CRP) level (≥100 mg/l). 59% of all in-hospital deaths occurred in previously healthy people. Conclusions Pandemic H1N1 infection causes disease requiring hospitalisation of previously fit individuals as well as those with underlying conditions. An abnormal chest x-ray or a raised CRP level, especially in patients who are recorded as obese or who have pulmonary conditions other than asthma or COPD, indicate a potentially serious outcome. These findings support the use of pandemic vaccine in pregnant women, children <5 years of age and those with chronic lung disease. PMID:20627925

    For accurate diagnosis and prognostic prediction of acquired brain injury (ABI), it is crucial to understand the neurobiological mechanisms underlying loss of consciousness. However, there is no consensus on which regions and networks act as biomarkers for consciousness level and recovery outcome in ABI. Using resting-state fMRI, we assessed intrinsic functional connectivity strength (FCS) of whole-brain networks in a large sample of 99 ABI patients with varying degrees of consciousness loss (including fully preserved consciousness state, minimally conscious state, unresponsive wakefulness syndrome/vegetative state, and coma) and 34 healthy control subjects. Consciousness level was evaluated using the Glasgow Coma Scale and Coma Recovery Scale-Revised on the day of fMRI scanning; recovery outcome was assessed using the Glasgow Outcome Scale 3 months after the fMRI scanning. One-way ANOVA of FCS, Spearman correlation analyses between FCS and the consciousness level and recovery outcome, and FCS-based multivariate pattern analysis were performed. We found decreased FCS with loss of consciousness primarily distributed in the posterior cingulate cortex/precuneus (PCC/PCU), medial prefrontal cortex, and lateral parietal cortex. The FCS values of these regions were significantly correlated with consciousness level and recovery outcome. Multivariate support vector machine discrimination analysis revealed that the FCS patterns predicted whether patients with unresponsive wakefulness syndrome/vegetative state and coma would regain consciousness with an accuracy of 81.25%, and the most discriminative region was the PCC/PCU. These findings suggest that intrinsic functional connectivity patterns of the human posteromedial cortex could serve as a potential indicator for consciousness level and recovery outcome in individuals with ABI. SIGNIFICANCE STATEMENT Varying degrees of consciousness loss and recovery are commonly observed in acquired brain injury patients, yet the

    We present a 15 year institutional analysis of the factors affecting progression free survival (PFS) and overall survival (OS) in patients undergoing attempted resection of adult intramedullary spinal cord ependymomas. Intramedullary spinal cord tumors are rare but important clinical entities, and ependymomas are the most commonly encountered intramedullary tumor. In total, 53 adult patients over the span of 15 years were analyzed for OS, PFS, and the effects of plane of dissection (POD) and gross total resection (GTR) on functional and long term outcomes. The mean age was 45 years and median follow-up was 54 months. The follow-up neurological outcome and modified McCormick scale were used to determine the functional outcome. Kaplan-Meier curves were used to calculate progression and survival. The overall ability to achieve GTR was significantly correlated to identification of an intraoperative POD (p<0.001). There was a trend towards increased PFS with the ability to achieve a GTR. There was no significant difference in the pre- and postoperative functional outcome scores. The ability to achieve a GTR is strongly correlated to the identification of a POD in ependymomas. There is a trend towards an increased probability of PFS in intramedullary spinal cord tumors when GTR is achieved. The resection of these tumors is likely to halt, but not reverse, neurological deterioration. PMID:26234635

  17. Functional and neuropsychological late outcomes in posterior fossa tumors in children.

    2015-10-01

    Tumors of the posterior fossa (PF) account for up to 60 % of all childhood intracranial tumors. Over the last decades, the mortality rate of children with posterior fossa tumors has gradually decreased. While survival has been the primary objective in most reports, quality of survival increasingly appears to be an important indicator of a successful outcome. Children with a PF tumor can sustain damage to the cerebellum and other brain structures from the tumor itself, concomitant hydrocephalus, the consequences of treatment (surgery, chemotherapy, radiotherapy), or a combination of these factors. Together, these contribute to long-term sequelae in physical functioning, neuropsychological late outcomes (including academic outcome, working memory, perception and estimation of time, and selective attention, long-term neuromotor speech deficits, and executive functioning). Long-term quality of life can also be affected by endocrinological complication or the occurrence of secondary tumors. A significant proportion of survivors of PF tumors require long-term special education services and have reduced rates of high school graduation and employment. Interventions to improve neuropsychological functioning in childhood PF tumor survivors include (1) pharmacological interventions (such as methylphenidate, modafinil, or donepezil), (2) cognitive remediation, and (3) home-based computerized cognitive training. In order to achieve the best possible outcome for survivors, and ultimately minimize long-term complications, new interventions must be developed to prevent and ameliorate the neuro-toxic effects experienced by these children.

    Background: A complex nonunion of the shaft of the tibia is a major cause of morbidity and mortality in patients with lower extremity injuries. Aims: The aim of this study was to evaluate the outcome of the functional and radiological outcome of complex nonunion shaft of tibia, treated by radical debridement, Ilizarov ring fixator with compression and distraction osteogenesis. Methods: From 2005 to 2010, sixty cases of complex nonunion shaft of tibia were included in our study. All infected nonunions were managed by radical debridement, fixed with Ilizarov ring fixator, monofocal/bifocal compression, and distraction osteogenesis. The average duration of follow-up is 36 months (26–50 months). The functional evaluation was done by using Association for the Study and Application of Methods of Ilizarov (ASAMI) scoring system and bone union with serial radiographs. Results: All patients had a successful union. The mean time for union was 7 months (5–9 months). The mean time of fixator removal is 12 months (8–14 months). Every patient had pin tract infections which were successfully treated with oral antibiotics. Four patients had an equinus deformity, one patient had insignificant limb shortening (1.5 cm), and three patients had soft tissue dystrophy. Using the ASAMI scoring system, we obtained 45 excellent, 10 good, 3 fair, and 2 poor functional results. Conclusions: The Ilizarov technique for complex nonunions has a high rate of success in achieving union and eradicating infection, bone loss, and malalignment. Radical debridement is the key step to control bone infection. PMID:27226689

    We analyzed preoperative patient characteristics and postoperative functional outcomes to identify the most predictive preoperative characteristics of postoperative functional outcome for Cruciate Retaining (CR) TKA. In a prospective, multicenter study, 307 knees with minimum 2-year follow-up were first divided into groups based on 2-year functional performance. Logistic regression then determined SF-36 General Health Score (GHS) to be the most predictive preoperative patient characteristic. Subsequently, a second analysis was performed using preoperative SF-36 GHS to stratify patients into groups. Statistical significance was achieved in both analyses by gender, BMI and hypertension. Statistical significance was achieved in a single analysis by age, preoperative narcotic use, preoperative metabolic medication usage, preoperative pulmonary disease and preoperative use of medication for anxiety or depression.

    Inflammatory markers have been associated with functional outcome and mortality of stroke. We investigated the changes in procalcitonin (PCT) and high-sensitivity C-reactive protein (Hs-CRP) levels during the acute period of ischemic stroke and evaluated the relationship between these levels and the long-term functional outcome and mortality. We prospectively studied 376 patients with acute ischemic stroke (AIS) who were admitted within 24 h after the onset of symptoms. PCT, Hs-CRP, and NIH Stroke Scale (NIHSS) were measured at the time of admission. Long-term functional outcome were measured by modified Rankin scale (mRS) at 1 year after admission. The correlations between the levels of PCT, Hs-CRP, and mortality at 1 year after stroke onset were analyzed. Patients with poor with functional outcome and non-survivors had significantly increased PCT and Hs-CRP levels on admission. Multivariate logistic regression analysis showed that PCT was an independent prognostic marker of 1-year functional outcome and death [odds ratio (OR) 2.33 (95% CI, 1.33-3.44) and 3.11 (2.02-4.43), respectively, P < 0.0001 for both, adjusted for age, NIHSS, other predictors, and vascular risk factors] in patients with AIS. The area under the receiver operating characteristic curve of PCT was 0.77 (95% CI, 0.72-0.83) for functional outcome and 0.88 (95% CI, 0.84-0.93) for mortality. PCT improved the area under the receiver operating characteristic curve of the NIHSS score for functional outcome from 0.74 (95% CI, 0.66-0.81) to 0.85 (95% CI, 0.76-0.92; P < 0.0001) and for mortality from 0.77 (95% CI, 0.70-0.83) to 0.94 (95% CI, 0.89-0.97; P < 0.0001). Serum level of PCT at admission was an independent predictor of long-term functional outcome and mortality after ischemic stroke in Chinese sample. PMID:25650122

    Objective To investigate the association of family history of stroke with functional outcomes in stroke patients in Korea. Methods A case-control study was conducted. A total of 170 patients who were admitted to a rehabilitation unit were included. Risk factors for stroke such as age, sex, diabetes mellitus, hypertension, atrial fibrillation, smoking, high blood cholesterol and homocysteine level, obesity, and family history of stroke were taken into account. Stroke subtypes were the following: large vessel infarct, small vessel infarct, embolic infarct, subarachnoid hemorrhage, and intracranial hemorrhage. Stroke severity as assessed with the National Institutes of Health Stroke Scale (NIHSS), functional outcomes using the Korean version of the Modified Barthel index (K-MBI), Functional Independence Measurement (FIM), and cognitive function using the Korean version of Mini-Mental State Examination (K-MMSE) were assessed at admission and discharge. Results Subjects with a family history of stroke were more likely to have an ischemic stroke (90.7%) than were those without a family history (70.9%). The K-MBI, FIM, NIHSS, and K-MMSE scores did not show significant differences between patients with or without family history. Conclusion Family history of stroke was significantly associated with ischemic stroke, but not with functional outcomes. Other prognostic factors of stroke were not distributed differently between patients included in this study with or without a family history of stroke. PMID:26798613

    Pneumococcal meningitis is the most common and severe form of bacterial meningitis. Fatality rates are substantial, and long-term sequelae develop in about half of survivors. Here, we have performed a prospective nationwide genetic association study using the Human Exome BeadChip and identified gene variants in encoding dynactin 4 (DCTN4), retinoic acid early transcript 1E (RAET1E), and V-akt murine thymoma viral oncogene homolog 3 (AKT3) to be associated with unfavourable outcome in patients with pneumococcal meningitis. No clinical replication cohort is available, so we validated the role of one of these targets, AKT3, in a pneumococcal meningitis mouse model. Akt3 deficient mice had worse survival and increased histopathology scores for parenchymal damage (infiltration) and vascular infiltration (large meningeal artery inflammation) but similar bacterial loads, cytokine responses, compared to wild-type mice. We found no differences in cerebrospinal fluid cytokine levels between patients with risk or non-risk alleles. Patients with the risk genotype (rs10157763, AA) presented with low scores on the Glasgow Coma Scale and high rate of epileptic seizures. Thus, our results show that AKT3 influences outcome of pneumococcal meningitis. PMID:27193124

    INTRODUCTION Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA). METHODS 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months. RESULTS Both groups showed a significant difference in all algofunctional KOOS subscales (p < 0.001). The mean score difference at six weeks and three months was not significant in the sports and recreational activities subscale for both groups (p > 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928). CONCLUSION Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA. PMID:26996450

    Three patients with poor left ventricular function (left ventricular ejection fraction <30 %) developed postoperative atrial tachyarrhythmia in intensive care. Case 1 was a 64-year-old man who underwent a modified Bentall procedure and mitral valve annuloplasty. Case 2 was a 63-year-old woman who underwent quintuple coronary artery bypass grafting. Case 3 was a 65-year-old man who underwent mitral valve replacement. Preoperative intra-aortic balloon pumping was required in Cases 2 and 3. Excellent heart rate control with no hemodynamic deterioration was achieved in all three cases by very-low-dose continuous drip infusion of landiolol hydrochloride (2-5 μg/kg/min). Very-low-dose continuous drip infusion of landiolol hydrochloride is a safe and useful alternative for the control of perioperative atrial tachyarrhythmias in patients with poor left ventricular function.

    Cyclic nucleotide-gated (CNG) ion channels, despite a significant homology with the highly selective K(+) channels, do not discriminate among monovalent alkali cations and are permeable also to several organic cations. We combined electrophysiology, molecular dynamics (MD) simulations, and X-ray crystallography to demonstrate that the pore of CNG channels is highly flexible. When a CNG mimic is crystallized in the presence of a variety of monovalent cations, including Na(+), Cs(+), and dimethylammonium (DMA(+)), the side chain of Glu66 in the selectivity filter shows multiple conformations and the diameter of the pore changes significantly. MD simulations indicate that Glu66 and the prolines in the outer vestibule undergo large fluctuations, which are modulated by the ionic species and the voltage. This flexibility underlies the coupling between gating and permeation and the poor ionic selectivity of CNG channels. PMID:26100907

    To address the impact of cellular origin on acute myeloid leukemia (AML), we generated an inducible transgenic mouse model for MLL-AF9-driven leukemia. MLL-AF9 expression in long-term hematopoietic stem cells (LT-HSC) in vitro resulted in dispersed clonogenic growth and expression of genes involved in migration and invasion. In vivo, 20% LT-HSC-derived AML were particularly aggressive with extensive tissue infiltration, chemoresistance, and expressed genes related to epithelial-mesenchymal transition (EMT) in solid cancers. Knockdown of the EMT regulator ZEB1 significantly reduced leukemic blast invasion. By classifying mouse and human leukemias according to Evi1/EVI1 and Erg/ERG expression, reflecting aggressiveness and cell of origin, and performing comparative transcriptomics, we identified several EMT-related genes that were significantly associated with poor overall survival of AML patients.

    Galectin-9 is a widely expressed protein that is involved in immune regulation and tumorpathogenesis and serves as a marker of a poor prognosis in various types of cancers. However, the clinical impact and the precise mechanism by which this protein contributes to colon tumor progression are unclear. In the present study, we detected the expression of galectin-9 and CD56 cells using immunohistochemistry. Spearman's rank correlation was used to clarify the association between galectin-9 expression and natural killer (NK) cell infiltration. The influence of galectin-9 on NK-92 cell migration was evaluated in vitro using transwell chemotaxis assays. The role of rh-galectin-9 in F-actin polarization in NK-92 cells was investigated using laser scanning confocal microscopy. We showed that galectin-9 was expressed in 101 (78.91%) colon tumor tissues and that was expressed at lower levels in these tissues than in para-tumor tissues. Low levels of galectin-9 expression were positively correlated with a poor histological grade and lymph node metastasis (P<0.05). A Kaplan-Meier method and Cox proportional hazards regression analysis showed that overall survival was longer in patients with high galectin-9 expression in an 8-year follow-up (P<0.05). Spearman's rank correlation indicated that there was a linear correlation between galectin-9 expression and CD56+ NK cell infiltration (R2 = 0.658; P<0.0001). Galectin-9 stimulated migration in human NK-92 cells by affecting F-actin polarization through the Rho/ROCK1 signaling pathway. These results suggest that galectin-9 expression potentially represents a novel mechanism for tumors to escape immune surveillance in colon tumors. PMID:27028892

    Insomnia is a common yet often unrecognized symptom in patients with depression and anxiety. Because of its association with functional impairment, medical conditions, and disturbances in multiple body systems, insomnia must be included in the treatment of depression and anxiety disorders. If left untreated, insomnia may increase the risk of episode recurrence, severe illness course, and poor treatment response. However, these risks may be diminished with effective insomnia treatment.

    Context Psychiatric problems are among the most common health problems of childhood. Objective To test whether these health problems adversely affect adult functioning even if the problems themselves do not persist. Design Prospective, population-based study of 1420 participants assessed with structured interviews up to 6 times in childhood (ages 9 to 16; 6674 observations) for common psychiatric diagnoses and subthreshold psychiatric problems. Setting and population Community sample. Main outcome measure Participants were then assessed 3 times in young adulthood (ages 19, 21, and 24–26; 3215 observations of 1273 subjects) for adverse outcomes related to health, legal, financial, and social functioning. Results Participants with a childhood disorder had 6 times higher odds of at least one adverse adult outcome as compared to those with no history of psychiatric problems and 9 times higher odds of 2 or more such indicators (1 indicator: 59.5% vs. 19.9%, p <0.001; 2+ indicators: 34.2% vs. 5.6%, p <0.001). These associations persisted after statistically controlling for childhood psychosocial hardships and adult psychiatric problems. Risk was not limited to those with a diagnosis: participants with subthreshold psychiatric problems had 3 times higher odds of adult adverse outcomes and 5 time higher odds of 2 or more outcomes (1 indicator: 41.9% vs. 19.9%, p <0.001; 2+ indicators: 23.2% vs. 5.6%, p <0.001). The best diagnostic predictor of adverse outcomes was cumulative childhood exposure to psychiatric disorders. Conclusions Common, typically moderately-impairing, childhood psychiatric problems are associated with a disrupted transition to adulthood even if the problems do not persist into adulthood and even if the problems are subthreshold. Such problems provide potential target for public health efforts to ameliorate adult suffering and morbidity. PMID:26176785

    During microbial evolution, genome rearrangement increases with increasing sequence divergence. If the relationship between synteny and sequence divergence can be modeled, gene clusters in genomes of distantly related organisms exhibiting anomalous synteny can be identified and used to infer functional conservation. We applied the phylogenetic pairwise comparison method to establish and model a strong correlation between synteny and sequence divergence in all 634 available Archaeal and Bacterial genomes from the NCBI database and four newly assembled genomes of uncultivated Archaea from an acid mine drainage (AMD) community. In parallel, we established and modeled the trend between synteny and functional relatedness in the 118 genomes available in the STRING database. By combining these models, we developed a gene functional annotation method that weights evolutionary distance to estimate the probability of functional associations of syntenous proteins between genome pairs. The method was applied to the hypothetical proteins and poorly annotated genes in newly assembled acid mine drainage Archaeal genomes to add or improve gene annotations. This is the first method to assign possible functions to poorly annotated genes through quantification of the probability of gene functional relationships based on synteny at a significant evolutionary distance, and has the potential for broad application.

    Background There are limited data about the epidemiology and treatment-related outcomes associated with capreomycin resistance in patients with XDR-TB. Capreomycin achieves high serum concentrations relative to MIC but whether capreomycin has therapeutic benefit despite microbiological resistance remains unclear. Methods We reviewed the susceptibility profiles and outcomes associated with capreomycin usage in patients diagnosed with XDR-TB between August 2002 and October 2012 in two provinces of South Africa. Patients whose isolates were genotypically tested for capreomycin resistance were included in the analysis. Results Of 178 XDR-TB patients 41% were HIV-infected. 87% (154/178) isolates contained a capreomycin resistance-conferring mutation [80% (143/178) rrs A1401G and 6% (11/178) were heteroresistant (containing both the rrs A1401G mutation and wild-type sequences)]. Previous MDR-TB treatment, prior usage of kanamycin, or strain type was not associated with capreomycin resistance. 92% (163/178) of XDR-TB patients were empirically treated with capreomycin. Capreomycin resistance decreased the odds of sputum culture conversion. In capreomycin sensitive and resistant persons combined weight at diagnosis was the only independent predictor for survival (p=<0.001). By contrast, HIV status and use of co-amoxicillin/clavulanic acid were independent predictors of mortality (p=<0.05). Capreomycin usage was not associated with survival or culture conversion when the analysis was restricted to those whose isolates were resistant to capreomycin. Conclusion In South Africa the frequency of capreomycin conferring mutations was extremely high in XDR-TB isolates. In those with capreomycin resistance there appeared to be no therapeutic benefit of using capreomycin. These data inform susceptibility testing and the design of treatment regimens for XDR-TB in TB endemic settings. PMID:25909847

    Objective Disruptive mood dysregulation disorder is a new disorder for DSM-5 that is uncommon and frequently co-occurs with other psychiatric disorders. Here, we test whether meeting diagnostic criteria for this disorder in childhood predicts adult diagnostic and functional outcomes. Methods In a prospective, population-based study, subjects were assessed with structured interviews up to 6 times in childhood and adolescence (ages 10 to 16; 5336 observations of 1420 subjects) for symptoms of disruptive mood dysregulation disorder and 3 times in young adulthood (ages 19, 21, and 24-26; 3215 observations of 1273 subjects) for psychiatric and functional outcomes (health, risky/illegal behavior, financial/educational and social functioning). Results Young adults with a history of childhood disruptive mood dysregulation disorders had elevated rates of anxiety and depression and were more likely to meet criteria for more than one adult disorder as compared to controls with no history of childhood psychiatric problems (noncases) or subjects meeting criteria for psychiatric disorders other than disruptive mood dysregulation disorder in childhood/adolescence (psychiatric controls). Participants with a history of disruptive mood dysregulation disorder also were more likely to have adverse health outcomes, be impoverished, have reported police contact, and have low educational attainment as adults compared to either psychiatric or noncase controls. Conclusions The long-term prognosis of children with disruptive mood dysregulation disorder cases is one of pervasive impaired functioning that in many cases is worse than that of other childhood psychiatric cases.

    Individuals with schizophrenia face significant challenges in daily functioning, and although social cognition predicts how well patients respond to these challenges, associated physiological mechanisms remain unspecified. The present study draws from polyvagal theory and tested the hypothesis that respiratory sinus arrhythmia (RSA), an established indicator of the capacity to self-regulate and adapt to environmental demands, combines with social cognition to predict functional outcome. Using data from 41 schizophrenia patients and 36 healthy comparison subjects, we replicated group differences in RSA and social cognition and also demonstrated that RSA and social cognition interact to predict how effectively patients manage work and independent living activities. Specifically, RSA did not enhance functional outcomes when social cognition was already strong, but higher levels of RSA enabled effective role functioning when social-cognitive performance was impaired. Jointly, RSA and social cognition accounted for 40% of the variance in outcome success, compared with 21% when evaluating social cognition alone. As polyvagal theory suggests, physiological flexibility and self-regulatory capacity may compensate for poorer social-cognitive skills among schizophrenia patients. PMID:25314266

    Identifying biosignatures to assess the probability of response to an antidepressant for patients with major depressive disorder (MDD) is critically needed. Functional connectivity MRI (fcMRI) offers the promise to provide such a measure. Previous work with fcMRI demonstrated that the correlation in signal from one region to another is a measure of functional connectivity. In this pilot work, a baseline non-task fcMRI was acquired in 14 adults with MDD who were free of all medications. Participants were then treated for 8 weeks with an antidepressant and then clinically re-evaluated. Probabilistic anatomic regions of interest (ROI) were defined for 16 brain regions (eight for each hemisphere) previously identified as being important in mood disorders. These ROIs were used to determine mean time courses for each individual's baseline non-task fcMRI. The correlations in time courses between 16 brain regions were calculated. These calculated correlations were considered to signify measures of functional connectivity. The degree of connectivity for each participant was correlated with treatment outcome. Among 13 participants with 8 weeks follow-up data, connectivity measures in several regions, especially the subcallosal cortex, were highly correlated with treatment outcome. These connectivity measures could provide a means to evaluate how likely a patient is to respond to an antidepressant treatment. Further work using larger samples is required to confirm these findings and to assess if measures of functional connectivity can be used to predict differential outcomes between antidepressant treatments.

    Background: In treatment of tumors, we usually reconstruct after resection of the entire femur using only metallic modular endoprostheses among many procedures and defined it as a total femur replacement. We studied the interrelation between the preservation of rectus femoris and the functional outcome after total femur replacement. Methods: We rated the functional outcomes of 21 patients who underwent total femur replacement. We categorized the subjects into 2 groups: group A (rectus femoris preserved) and group B (rectus femoris unpreserved). We examined them based on the Mann-Whitney U test between the 2 groups in average through the Musculoskeletal Tumor Society functional scores. Results: The average score of group A was 20 of 25 (11–25; 80%), whereas the average score of group B was 10 of 25 (4–13; 40%). There was significant difference between the groups (P = 0.00168877). Conclusion: We found that the preservation of rectus femoris is imperative for achieving the favorable functional outcome in total femur replacement.

    Background and purpose Shoulder function may be changed after healing of a nonoperatively treated clavicular fracture, especially in cases of clavicular shortening or mal-union. We investigated scapular orientations and functional outcome in healed clavicular fractures with and without clavicular shortening. Patients and methods 32 participants with a healed nonoperatively treated midshaft clavicular fracture were investigated. Motions of the thorax, arm, and shoulder were recorded by standardized electromagnetic 3D motion tracking. The DASH score and Constant-Murley score were used to evaluate functional outcome. Orientation of the scapula and humerus at rest and during standardized tasks, and strength and function of the affected shoulders were compared with corresponding values for the uninjured contralateral shoulders. Results Mean clavicular shortening was 25 mm (SD 16). Scapula protraction had increased by mean 4.4° in rest position in the affected shoulders. During abduction, slightly more protraction, slightly more lateral rotation, and slightly less backward tilt was found for the affected shoulders. For anteflexion, the scapular orientations of the affected shoulders also showed slightly increased protraction, slightly increased lateral rotation, and slightly reduced backward tilt. Scapulohumeral kinematics, maximum humerus angles, and strength were not associated with the degree of clavicular shortening. All participants had excellent performance on the Constant-Murley score and DASH score. Interpretation Scapulohumeral kinematics in shoulders with a healed clavicular fracture differ from those in uninjured shoulders, but these changes are small, do not result in clinically relevant changes in outcome, and do not relate to the amount of clavicular shortening. These findings do not support routine operative reduction and fixation of shortened midshaft clavicular fractures based on the argument of functional outcome. PMID:25872962

    Background Chronic renal failure is characterized by progressive renal scarring and accelerated arteriosclerotic cardiovascular disease despite what is considered to be adequate hemodialysis or peritoneal dialysis. In rodents with reduced renal mass, renal scarring has been attributed to poorly filtered, small protein-bound molecules. The best studied of these is indoxyl sulfate (IS). Methods We have attempted to establish whether there are uremic toxins that are not effectively removed by hemodialysis. We examined plasma from patients undergoing hemodialysis, employing global gene expression in normal human renal cortical cells incubated in pre- and post- dialysis plasma as a reporter system. Responses in cells incubated with pre- and post-dialysis uremic plasma (n = 10) were compared with responses elicited by plasma from control subjects (n = 5). The effects of adding IS to control plasma and of adding probenecid to uremic plasma were examined. Plasma concentrations of IS were measured by HPLC (high pressure liquid chromatography). Results Gene expression in our reporter system revealed dysregulation of 1912 genes in cells incubated with pre-dialysis uremic plasma. In cells incubated in post-dialysis plasma, the expression of 537 of those genes returned to baseline but the majority of them (1375) remained dysregulated. IS concentration was markedly elevated in pre- and post-dialysis plasma. Addition of IS to control plasma simulated more than 80% of the effects of uremic plasma on gene expression; the addition of probenecid, an organic anion transport (OAT) inhibitor, to uremic plasma reversed the changes in gene expression. Conclusion These findings provide evidence that hemodialysis fails to effectively clear one or more solutes that effect gene expression, in our reporter system, from the plasma of patients with uremia. The finding that gene dysregulation was simulated by the addition of IS to control plasma and inhibited by addition of an OAT inhibitor to

    Alterations in the scaffold protein WRAP53β have previously been linked to carcinogenesis and, in particular, associated with an increased risk for epithelial ovarian cancer. Here, we investigated the pathogenic impact and prognostic significance of WRAP53β in connection with epithelial ovarian cancer and examined the underlying mechanisms. We find that reduced expression of WRAP53β in ovarian tumors correlated with attenuated DNA damage response and poor patient survival. Furthermore, in ovarian cancer cell lines, WRAP53β was rapidly recruited to DNA double-strand breaks, where it orchestrated the recruitment of repair factors involved in homologous recombination and non-homologous end joining, including RNF168, 53BP1, BRCA1 and RAD51. Mechanistically, WRAP53β accomplishes this by facilitating the necessary ubiquitinylation at DNA breaks. Finally, we demonstrate that loss of WRAP53β significantly impairs the repair of DNA double-strand breaks, resulting in their accumulation. Our findings establish WRAP53β as a regulator of homologous recombination and non-homologous end joining repair in ovarian cancer cells, suggesting that loss of this protein contributes to the development and/or progression of ovarian tumors. Moreover, our current observations identify the nuclear levels of WRAP53β as a promising biomarker for the survival of patients with ovarian cancer. PMID:26426684

    Objective Research has examined the effects of parental psychopathology, family functioning, and caregiver strain on treatment response in anxious youths. Although these variables have shown individual links to youth treatment response, theoretical models for their combined effects remain unexplored. This study tested the hypothesis that improvements in family functioning and reductions in caregiver strain explained the effects of parental psychopathology on youth treatment outcome in an anxiety treatment trial. Method A multiple mediation technique was used to test the proposed model across independent evaluator (IE), parent, and youth informants in 488 youths, aged 7–17 years (50% female; mean age 10.7) meeting DSM-IV-TR criteria for social phobia, separation anxiety, and/or generalized anxiety disorder. Youths were randomized to receive 12 weeks of cognitive-behavioral treatment (Coping Cat), medication (sertraline), their combination, or a pill placebo. At pre- and post-treatment, parents completed self-report measures of global psychopathology symptoms, family functioning, and caregiver strain; parents, youths, and IEs rated youths’ anxiety symptom severity. Results Changes in family functioning and caregiver strain jointly explained relations between parental psychopathology and reductions in youth anxiety. Specifically, across IE and parent informants, families with higher pre-treatment parental psychopathology showed more improvement in family functioning and caregiver strain, which in turn predicted greater youth anxiety reductions. Further, higher pre-treatment parental psychopathology predicted greater caregiver strain reductions, and in turn, greater youth anxiety reductions, based on youths’ reports of their own anxiety. Conclusions Findings suggest that improvements in family functioning and reductions in caregiver strain can influence treatment outcomes for anxious youths, especially among youths with more distressed parents.

    This study examined executive functioning and reading achievement in 106 6- to 8-year-old Brazilian children from a range of social backgrounds of whom approximately half lived below the poverty line. A particular focus was to explore the executive function profile of children whose classroom reading performance was judged below standard by their teachers and who were matched to controls on chronological age, sex, school type (private or public), domicile (Salvador/BA or São Paulo/SP) and socioeconomic status. Children completed a battery of 12 executive function tasks that were conceptual tapping cognitive flexibility, working memory, inhibition and selective attention. Each executive function domain was assessed by several tasks. Principal component analysis extracted four factors that were labeled "Working Memory/Cognitive Flexibility," "Interference Suppression," "Selective Attention," and "Response Inhibition." Individual differences in executive functioning components made differential contributions to early reading achievement. The Working Memory/Cognitive Flexibility factor emerged as the best predictor of reading. Group comparisons on computed factor scores showed that struggling readers displayed limitations in Working Memory/Cognitive Flexibility, but not in other executive function components, compared to more skilled readers. These results validate the account that working memory capacity provides a crucial building block for the development of early literacy skills and extends it to a population of early readers of Portuguese from Brazil. The study suggests that deficits in working memory/cognitive flexibility might represent one contributing factor to reading difficulties in early readers. This might have important implications for how educators might intervene with children at risk of academic under achievement. PMID:24959155

    The current study examined the relation between parental expressed emotion (EE) and treatment outcome among adolescents participating in a treatment study for adolescent anorexia nervosa, as well as its impact on family functioning. One hundred and twenty-one families were assigned to family-based treatment or adolescent-focused therapy. Paternal criticism predicted lesser improvement in eating disorder psychopathology at end of treatment. There was also a significant interaction between maternal hostility and treatment, indicating that adolescents whose mothers displayed hostility had greater increases in percent of expected body weight in adolescent-focused therapy than family-based treatment. In addition, maternal hostility predicted less improvement in general family functioning and family communication at the end of treatment. Findings suggest that maternal and paternal EE may differentially impact treatment outcome and should be directly attended to in clinical settings. Future research is needed to further explore ways in which parental EE can be effectively modified in treatment. PMID:26201083

    Purpose: Retrospective review describing the 35-year University of Florida experience with Ewing's tumors of the lower extremity. Patients and Methods: Fifty-three patients were treated between 1971 and 2006. Thirty patients were treated with radiotherapy (RT) alone and 23 patients were treated with surgery {+-} RT. Larger tumors and tumors of the femur were treated more often with definitive RT. Median potential follow-up was 19.2 years. Functional outcome was assessed using the Toronto Extremity Salvage Score (TESS). Results: Before 1985, 24% of patients were treated with surgery; since then, the rate has increased to 61%. The 15-year actuarial overall survival (OS), cause-specific survival (CSS), freedom from relapse, and limb preservation rates were 68% vs. 47% (p = 0.21), 73% vs. 47% (p = 0.13), 73% vs. 40% (p = 0.03), and 43% vs. 40% (p = 0.52), respectively, for patients treated with surgery {+-} RT vs. RT alone. Excluding 8 patients who underwent amputation or rotationplasty, the 15-year actuarial local control rate was 100% for the surgery {+-} RT group and 68% for the definitive RT group (p = 0.03). The ranges of the TESS for surgery {+-} RT vs. RT alone were 70-100 (mean, 94) and 97-100 (mean, 99), respectively. Twenty-six percent (6/23) of patients had complications related to surgery requiring amputation or reoperation. Conclusions: Overall survival and CSS were not statistically compromised, but we observed an increased risk of relapse and local failure in patients treated with RT alone, thereby justifying a transition toward primary surgical management in suitable patients. However, despite an adverse risk profile, patients treated with RT alone had similar long-term amputation-free survival and demonstrated comparable functional outcomes. Poor results observed in Ewing's of the femur mandate innovative surgical and RT strategies.

    The protein phosphatase 2A (PP2A) is a key tumor suppressor which has emerged as a novel molecular target in some human cancers. Here, we show that PP2A inhibition is a common event in breast cancer and identified PP2A phosphorylation and deregulation SET and CIP2A as molecular contributing mechanisms to inactivate PP2A. Interestingly, restoration of PP2A activity after FTY720 treatment reduced cell growth, induced apoptosis and decreased AKT and ERK activation. Moreover, FTY720 led to PP2A activation then enhancing doxorubicin-induced antitumor effects both in vitro and in vivo. PP2A inhibition (CPscore: PP2A phosphorylation and/or CIP2A overexpression) was detected in 27% of cases (62/230), and associated with grade (p = 0.017), relapse (p < 0.001), negative estrogen (p < 0.001) and progesterone receptor expression (p < 0.001), HER2-positive tumors (p = 0.049), Ki-67 expression (p < 0.001), and higher AKT (p < 0.001) and ERK (p < 0.001) phosphorylation. Moreover, PP2A inhibition determined shorter overall (p = 0.006) and event-free survival (p = 0.003), and multivariate analysis confirmed its independent prognostic impact. Altogether, our results indicate that PP2A is frequently inactivated in breast cancer and determines worse outcome, and its restoration using PP2A activators represents an alternative therapeutic strategy in this disease.

    The tumour subtype, TNM classification, and histopathological data are sometimes not sufficient for understanding and assessing the behaviour of oral cancers. In an attempt to find additional markers of tumour biology and behaviour, this study sought to determine the incidence and consequently the relevance of c-erb-B2, c-Myc, and H-ras gene alterations in tumour-free margins of oral squamous cell carcinoma (OSCC). Fifty samples of OSCC were analyzed for c-erb-B2 and c-Myc amplification by real-time polymerase chain reaction and for H-ras point mutations by sequencing. A relatively high incidence of genetic lesions was detected: 22% of cases had c-erb-B2 and 30% had c-Myc amplification, whilst only 12% harboured H-ras mutations. Kaplan-Meier analysis and the log-rank test showed statistically significant differences in 5-year survival rates and relapse between patients with tumour margins positive for c-erb-B2 amplification and those with margins that were negative (P=0.002). H-ras and c-Myc alterations could not be associated with tumour behaviour. Molecular analysis of margins, targeting cancer genes, could identify additional, independent predictors of risk and outcome in OSCC. PMID:26708050

    Survivin, a member of the inhibitors of apoptosis protein family, plays important roles in cell proliferation and survival and is highly expressed in various malignancies, including leukemias. To better understand its role in acute myeloid leukemia (AML), we profiled survivin expression in samples obtained from 511 newly diagnosed AML patients and in CD34+38− AML stem/progenitor cells using a validated reverse-phase protein array; we correlated its levels with clinical outcomes and with levels of other proteins in the same sample set. We found that survivin levels were higher in bone marrow than in paired peripheral blood leukemic cells (n = 140, P = .0001) and that higher survivin levels significantly predicted shorter overall (P = .016) and event-free (P = .023) survival in multivariate Cox model analysis. Importantly, survivin levels were significantly higher in CD34+38− AML stem/progenitor cells than in bulk blasts and total CD34+ AML cells (P < .05). Survivin expression correlated with the expressions of multiple proteins involved with cell proliferation and survival. Particularly, its expression strongly correlated with HIF1α in the stem/progenitor cell compartment. These results suggest that survivin is a prognostic biomarker in AML and that survivin, which is overexpressed in AML stem/progenitor cells, remains a potentially important target for leukemia therapy.

    Background Recurrent anterior shoulder dislocations are common in young patients with Bankart lesions. Arthroscopic repair is an established treatment; however, recurrent instability occurs in up to 35% of patients. It is unclear whether recurrence is the result of a failure of the surgical repair to heal or a repeat injury. The aim of the present pilot study was to assess radiographic healing of Bankart lesions 6 months post surgical repair and identify any correlations between radiographic findings and subsequent recurrent dislocations. Methods Eighteen patients underwent arthroscopic Bankart repair for recurrent instability. Magnetic resonance (MR) arthrograms were obtained both pre-operatively and 6 months postoperatively. Standard T1 and T2 views were obtained along with an abduction and external rotation (ABER) view. Patients were followed for a minimum of 4 years for the risk of recurrence, and functional outcomes were obtained, including the American Shoulder and Elbow Surgeons Subjective Shoulder Scale, Ontario Shoulder Instability Index, Oxford Shoulder Instability Score and 12-Item Short Form Health Survey. Scores were correlated with pre-operative and postoperative MR findings. Results Six of 18 patients developed recurrent instability. We could not identify correlations between reconstructed labrum (labral bumper) position, failure at suture sites and ABER findings with recurrent instability or functional outcome. Paradoxically, there was a nonstatistically significant trend for patients with no clefts between the labrum and the glenoid at any points along the repair to have worse outcomes than patients with partial or complete clefts. Conclusions In our pilot study, MR arthrogram was used to evaluate the labrum in detail 6 months postoperatively. Despite its proven ability to detect labral lesions, we were unable to demonstrate any features on postoperative MR arthrogram that predicted either functional outcome or recurrent instability.

    BACKGROUND Although the assignment and suturing of the spreader graft to the septum is a routine part of rhinoplasty, it is a time wasting procedure and some problems may occur. Rather, autospreader flap is a new method that the dorsal part of the upper lateral cartilage is used as its own graft. In the present study, we intended to compare the functional and aesthetic outcomes of these two techniques of rhinoplasty. METHODS In a clinical trial, patients who referred to 15 Khordad Hospital for elective rhinoplasty during 2013-2014 were enrolled. The functional and aesthetic outcomes were compared between the two techniques of spreader graft and autospreader flap using rhinomanometry and satisfaction questionnaire in two stages before and one months after the surgery. RESULTS Total nasal airway resistance increased significantly by both spreader graft and autospreader flap, but the difference between the two methods was not statistically significant. The total nasal flow before and after the surgery significantly decreased using both techniques, but this reduction was not significant between the two methods of surgery. When questioned about the satisfaction with the surgery outcomes, 18 subjects (36%) had complete aesthetic satisfaction, 25 (50%) were partial satisfied and 7 subjects (14%) were unsatisfied from aesthetic results. The rate of patient’s satisfaction in both groups was higher for functional outcome. Overall, 32 (64%) subjects were completely satisfied, 13 (26%) were partially satisfied and 5 (10%) subjects did not report satisfaction. Loss of respiratory function in both groups was inevitable due to short time post-operative period. CONCLUSION Both spreader graft and autospreader flap techniques can be used in the preservation and restoration of the normal internal nasal valve angle, as well as restoration of dorsal aesthetic lines of the nasal dorsum.

    Introduction Electroencephalography (EEG) remains the most important investigative modality in the diagnostic evaluation of individuals with epilepsy. Children living with epilepsy in the developing world are faced with challenges of lack of access to appropriate diagnostic evaluation and a high risk of misdiagnosis and inappropriate therapy. We appraised EEG studies in a cohort of Nigerian children with epilepsy seen in a tertiary center in order to evaluate access to and the impact of EEG in the diagnostic evaluation of the cases. Methods Inter-ictal EEG was requested in all cases of pediatric epilepsy seen at the pediatric neurology clinic of the University College Hospital, Ibadan, Nigeria over a period of 18 months. Clinical diagnosis without EEG evaluation was compared with the final diagnosis post- EEG evaluation. Results A total of 329 EEGs were recorded in 329 children, aged 3months to 16 years, median 61.0 months. Clinical evaluation pre-EEG classified 69.3% of the epilepsies as generalized. The a posteriori EEG evaluations showed a considerably higher proportion of localization-related epilepsies (33.6%). The final evaluation post EEG showed a 21% reduction in the proportion of cases labeled as generalized epilepsy and a 55% increase in cases of localization-related epilepsy(p<0.001). Conclusion Here we show that there is a high risk of misdiagnosis and therefore the use of inappropriate therapies in children with epilepsy in the absence of EEG evaluation. The implications of our findings in the resource-poor country scenario are key for reducing the burden of care and cost of epilepsy treatment on both the caregivers and the already overloaded tertiary care services.

    The economic consequences of road traffic injuries (RTIs) are very important in terms of health care costs. The aim of this study is to provide estimates of health care costs of non-fatal RTIs and to estimate functional outcomes using in-hospital rehabilitation data. We identified all emergency department (ED) visits related to RTI during 2008 and then linked them with hospital discharges and rehabilitation admissions, health care costs following RTI were estimated from the integrated database. We performed an epidemiological evaluation of RTI with a comprehensive description of functional outcomes at 6 months. Health care costs have been estimated at about €80 million with a per person cost of €522. About 18% of the total cost was due to rehabilitation treatments. In multivariate analysis the variables that correlated better with higher total health care costs were: older age, injury severity, presence of spinal lesion. Patients requiring rehabilitation were: the elderly, patients suffering from a spinal cord injury and leg injuries. This study provides consistent health care cost estimates of RTI using administrative databases and it shows a picture of functional outcomes after RTI. Further research is needed for the estimation of other components of the total cost of RTI. PMID:25262669

    Participation in youth sports can be very beneficial, but children with Attention Deficit Hyperactivity Disorder (ADHD) may participate less often and less successfully. The current study evaluated functional sports outcomes for children with ADHD who attended an intensive behavioral treatment program that included a sports training component, and it compared outcomes to children with ADHD who did not attend the program. Results suggest that treatment resulted in significant improvements in many aspects of children’s sports functioning, including knowledge of game rules, in vivo game performance, and fundamental skill tasks (motor proficiency, ability to trap a soccer ball appropriately, reduced handball penalties in soccer, and improved ability to catch a baseball). Parents also reported improved sports skills and good sportsmanship in the treatment group. No differences between groups were evident on additional skill tasks evaluating accurately kicking a soccer ball, throwing a baseball, or hitting a baseball off a tee. These results suggest intensive behavioral intervention that includes sports training can significantly improve functional sports outcomes for young children with ADHD. PMID:24362766

    Predicting the functional outcomes of spinal cord disorder patients after medical treatments, such as a surgical operation, has always been of great interest. Accurate posttreatment prediction is especially beneficial for clinicians, patients, care givers, and therapists. This paper introduces a prediction method for postoperative functional outcomes by a novel use of Gaussian process regression. The proposed method specifically considers the restricted value range of the target variables by modeling the Gaussian process based on a truncated Normal distribution, which significantly improves the prediction results. The prediction has been made in assistance with target tracking examinations using a highly portable and inexpensive handgrip device, which greatly contributes to the prediction performance. The proposed method has been validated through a dataset collected from a clinical cohort pilot involving 15 patients with cervical spinal cord disorder. The results show that the proposed method can accurately predict postoperative functional outcomes, Oswestry disability index and target tracking scores, based on the patient's preoperative information with a mean absolute error of 0.079 and 0.014 (out of 1.0), respectively.

    Background Regional analgesia is more effective than conventional analgesia for controlling pain and may facilitate rehabilitation after large joint replacement in the short term. It remains unclear if regional anaesthesia improves functional outcomes after joint replacement beyond three months after surgery. Objectives To assess the effects of regional anaesthesia and analgesia on long-term functional outcomes 3, 6 and 12 months after elective major joint (knee, shoulder and hip) replacement surgery. Search methods We performed an electronic search of several databases (CENTRAL, MEDLINE, EMBASE, CINAHL), and handsearched reference lists and conference abstracts. We updated our search in June 2015. Selection criteria We included randomized controlled trials (RCTs) comparing regional analgesia versus conventional analgesia in patients undergoing total shoulder, hip or knee replacement. We included studies that reported a functional outcome with a follow-up of at least three months after surgery. Data collection and analysis We used standard methodological procedures expected by Cochrane. We contacted study authors for additional information. Main results We included six studies with 350 participants followed for at least three months. All of these studies enrolled participants undergoing total knee replacement. Studies were at least partially blinded. Three studies had a high risk of performance bias and one a high risk of attrition bias, but the risk of bias was otherwise unclear or low. Only one study assessed joint function using a global score. Due to heterogeneity in outcome and reporting, we could only pool three out of six RCTs, with range of motion assessed at three months after surgery used as a surrogate for joint function. All studies had a high risk of detection bias. Using the random-effects model, there was no statistically significant difference between the experimental and control groups (mean difference 3.99 degrees, 95% confidence interval (CI)

    Background It has been suggested that maternal vitamin D status in pregnancy influences the risk of asthma and atopy in the offspring. The epidemiological evidence to support these claims is conflicting and may reflect chance findings and differences in how vitamin D was assessed. Objective To examine the association between blood total maternal 25-hydroxy vitamin D (25(OH)D) concentrations in pregnancy and offspring asthma, atopy and lung function in the largest birth cohort study to date. Methods Participants were largely of white European origin and resident in the South West of England. We examined the associations of maternal 25(OH)D concentrations in pregnancy with the following outcomes in the offspring: wheeze, asthma, atopy, eczema, hayfever, at mean age 7.5 years (n = 3652–4696 depending on outcome), IgE at 7 years (n = 2915) and lung function and bronchial responsiveness at mean age 8.7 years (n = 3728–3784). Results Sixty-eight per cent of mothers had sufficient (> 50 nmol/L) concentrations of 25(OH)D, 27% were insufficient (27.5–49.99 nmol/L) and 5% were deficient (< 27.5 nmol/L). There was no evidence to suggest that maternal 25(OH)D concentration in pregnancy was associated with any respiratory or atopic outcome in the offspring. These findings remained after adjustment for season of measurement and for potential confounders. There was also no evidence that these relationships followed a non-linear form and no evidence that either deficient or high concentrations of maternal 25(OH)D were associated with atopic or respiratory outcomes. Conclusions We found no evidence that maternal blood 25(OH)D concentration in pregnancy is associated with childhood atopic or respiratory outcomes. PMID:24074336

    Objectives To examine clinical outcomes of an interdisciplinary day hospital treatment program (comprised of physical, occupational, and cognitive-behavioral therapies with medical and nursing services) for pediatric complex regional pain syndrome (CRPS). Methods The study is a longitudinal case series of consecutive patients treated in a day hospital pediatric pain rehabilitation program. Participants were 56 children and adolescents ages 8–18 years (median = 14 years) with CRPS spectrum conditions who failed to progress sufficiently with a previous outpatient and/or inpatient treatments. Patients participated in daily physical therapy, occupational therapy and psychological treatment and received nursing and medical care as necessary. The model places equal emphasis on physical and cognitive-behavioral approaches to pain management. Median duration of stay was 3 weeks. Outcome measures included assessments of physical, occupational, and psychological functioning at program admission, discharge, and at post-treatment follow-up at a median of 10 months post-discharge. Scores at discharge and follow-up were compared with measures on admission by Wilcoxon tests, paired t tests, or ANOVA as appropriate, with corrections for multiple comparisons. Results Outcomes demonstrate clinically and statistically significant improvements from admission to discharge in pain intensity (p<0.001), functional disability (p<0.001), subjective report of limb function (p<0.001), timed running (p<0.001) occupational performance (p<0.001), medication use (p<0.01), use of assistive devices (p<0.001), and emotional functioning (anxiety, p<0.001; depression, p<0.01). Functional gains were maintained or further improved at follow-up. Discussion A day-hospital interdisciplinary rehabilitation approach appears effective in reducing disability and improving physical and emotional functioning and occupational performance among children and adolescents with complex regional pain syndromes that

    Time estimation of short durations (under 1 sec) was examined in low-functioning individuals with autism spectrum disorder (ASD) and typically developing (TD) children matched on mental age. Temporal bisection and generalization tasks were used to examine basic perceptual timing mechanisms. For both tasks, the participants with ASD demonstrated less sensitivity to variability in short durations than the TD children, adding to a growing body of literature suggesting deficits in timing exist for longer durations. The results highlight the need to examine multiple levels of processing of time-related information from basic perceptual mechanisms to higher level cognitive mechanisms. PMID:24574256

    The relationship between early motor status and functional outcome after spinal cord injury (SCI) was evaluated prospectively in 52 quadriplegic and 26 paraplegic patients. Motor status was measured within 72 hours of injury and quantified with the Motor Index Score (MIS). Functional status was evaluated with the Modified Barthel Index (MBI). A senior physical therapist completed the MIS and the MBI when each patient was admitted to the spinal cord intensive care unit and every 30 days during rehabilitation. Early motor function was correlated with average daily improvement in functional status including self-care and mobility (p = .001). The initial MIS strongly correlated with functional status of quadriplegics at admission (p = .001), at 60 days, and at rehabilitation discharge (p = .001). In paraplegics, the overall MBI at admission, after 60 days of rehabilitation, and at discharge was not correlated with early motor function. However, the MIS correlated significantly with the MBI self-care subscore at 60 days and at discharge (p = .01), but not with the mobility subscore. The initial MIS was also significantly correlated to functional status at discharge in patients with complete lesions (p = .001), but was not related to functional status at discharge in patients with incomplete lesions. The MIS appears to be a useful tool in predicting function during rehabilitation, although individual differences in ambulation, particularly for patients with paraplegia, limit the predictive utility of this index.

    Purpose The 22q11.2 deletion syndrome is a common multisystem genomic disorder with congenital and later-onset manifestations, including congenital heart disease, intellectual disability, and psychiatric illness, that may affect long-term functioning. There are limited data on adult functioning in 22q11.2 deletion syndrome. Methods We used the Vineland Adaptive Behavior Scales to assess functioning in 100 adults with 22q11.2 deletion syndrome (n = 46 male; mean age = 28.8 (standard deviation = 9.7) years) where intellect ranged from average to borderline (n = 57) to mild intellectual disability (n = 43). Results More than 75% of the subjects scored in the functional deficit range. Although personal, vocational, and financial demographics confirmed widespread functional impairment, daily living skills and employment were relative strengths. Intelligence quotient was a significant predictor (P < 0.001) of overall and domain-specific adaptive functioning skills. A diagnosis of schizophrenia was a significant predictor (P < 0.05) of overall adaptive functioning, daily living skills, and socialization scores. Notably, congenital heart disease, history of mood/anxiety disorders, sex, and age were not significant predictors of functioning. Conclusion Despite functional impairment in adulthood that is primarily mediated by cognitive and psychiatric phenotypes, relative strengths in activities of daily living and employment have important implications for services and long-term planning. These results may help to inform expectations about outcomes for patients with 22q11.2 deletion syndrome. PMID:22744446

    Increased activity of MYC protein-family members is a common feature in many cancers. Using neuroblastoma as a tumor model, we established a microRNA (miRNA) signature for activated MYCN/c-MYC signaling in two independent primary neuroblastoma tumor cohorts and provide evidence that c-MYC and MYCN have overlapping functions. On the basis of an integrated approach including miRNA and messenger RNA (mRNA) gene expression data we show that miRNA activation contributes to widespread mRNA repression, both in c-MYC- and MYCN-activated tumors. c-MYC/MYCN-induced miRNA activation was shown to be dependent on c-MYC/MYCN promoter binding as evidenced by chromatin immunoprecipitation. Finally, we show that pathways, repressed through c-MYC/MYCN miRNA activation, are highly correlated to tumor aggressiveness and are conserved across different tumor entities suggesting that c-MYC/MYCN activate a core set of miRNAs for cooperative repression of common transcriptional programs related to disease aggressiveness. Our results uncover a widespread correlation between miRNA activation and c-MYC/MYCN-mediated coding gene expression modulation and further substantiate the overlapping functions of c-MYC and MYCN in the process of tumorigenesis.

    Temporal discounting is the tendency to devalue temporally distant rewards. Past studies have examined the k-value, the indifference point, and the area under the curve as dependent measures on this task. The current study included these three measures and a fourth measure, called the interest rate total score, which differentiated good from poor choices. The interest rate total score was based on scoring only those items in which the delayed choice should be preferred given the expected return based on simple interest rates. In addition, associations with several individual difference measures were examined including intelligence, executive functions (inhibition, working memory, and set-shifting), thinking dispositions [Need for Cognition and Consideration of Future Consequences (CFCs)] and engagement in substance use and gambling behavior. A staircase temporal discounting task was examined in a sample of 99 university students. Replicating previous studies, temporal discounting increased with longer delays to reward and decreased with higher reward magnitudes. A hyperbolic function accounted for more variance in temporal discounting than an exponential function. Reaction time at the indifference point was significantly longer than at the other choice points. The four dependent measures of temporal discounting were all significantly correlated and were also significantly associated with our individual difference measures. That is, the tendency to wait for a larger delayed reward on all of the temporal discounting measures was associated with higher intelligence, higher executive functions, and more CFCs. Associations between our measures of temporal discounting and outcomes related to substance use and gambling behavior were modest in our university sample. PMID:26097462

  8. Obesity and long term functional outcomes following elective total hip replacement

    PubMed Central

    2012-01-01

    Introduction Obesity rates continue to rise and more total hip arthroplasty procedures are being performed in progressively younger, obese patients. Hence, maintenance of long term physical function will become very important for quality of life, functional independence and hip prosthesis survival. Presently, there are no reviews of the long term efficacy of total hip arthroplasty on physical function. This review: 1) synopsized available data regarding obesity effects on long term functional outcomes after total hip arthroplasty, and 2) suggested future directions for research. Methods A literature search was conducted from 1965 to January of 2011 for studies that evaluated long term functional outcomes at one year or longer after THA in obese (body mass index values ≥30 kg/m2) and non-obese patients (body mass index <30 kg/m2). Results Five retrospective studies and 18 prospective studies were identified as those that assessed physical function before surgery out to ≥ one year after total hip arthroplasty. Study sample sizes ranged from 108–18,968 and followed patients from one to twenty years. Total hip arthroplasty confers significant pain reduction and improvement in quality of life irrespective of body mass index. Functional improvement occurred after total hip arthroplasty among all studies, but obese patients generally did not attain the same level of physical function by the follow-up time point. Discussion Uncontrolled obesity after total hip arthroplasty is related to worsening of comorbidities and excessive health care costs over the long term. Aggressive and sustainable rehabilitation strategies that include physical exercise, psychosocial components and behavior modification may be highly useful in maximizing and maintaining weight loss after total hip arthroplasty.

    Objectives: Allografts have potential advantages in primary anterior cruciate ligament reconstruction (ACLR), including the absence of donor site morbidity, shorter operative times, improved cosmesis, and easier rehabilitation. There is limited and conflicting outcome data for ACLR with tibialis anterior allograft. The purpose of this study was to evaluate the functional outcomes of ACLR with tibialis anterior allograft. Methods: We retrospectively evaluated patients underwent ACLR using with tibialis anterior allograft between 2005 and 2013. Totally 12 patients who were performed suspensory fixation technique were included in this study (range: 25-43 years). Exclusion criteria included double bundle, bone tendon bone technique and revision surgery. Clinical outcomes were measured by subject part of International Knee Documentation Committee (IKDC) and Lysholm scores. Results: A significant increase was reported in all the clinical scores. In particular, the IKDC-subjective score increased from a basal value of 45.5±12.7 to 84.3±5.50 at the 12 months' evaluation (p<0.05). The Lysholm score revealed a significant improvement from 49.7±14.2 to 83.5±20.5 at the 12 months' evaluation (p<0.05). Conclusion: ACLR with tibialis anterior allograft is an effective treatment for correcting loss of function and increasing quality of life.

    This research investigates selected South Dakota science educational outcomes as a function of selected educational reform policies. In the state of South Dakota, echoing divergent reform initiatives from "A Nation at Risk" to "No Child Left Behind," new guidelines and requirements have been instituted. Yet, very little effort has been made to assess the progress of these educational changes. In this study, selected educational outcomes-SAT8/9/10 scores-as a function of selected South Dakota educational reform policies were examined. School districts, ranked in the top and bottom five percent of socioeconomic status (SES) in the state, were selected for analysis. Comparison on student's science educational outcomes was also be made between the two major ethnic populations-Caucasians and Native Americans. All research questions were stated in the null form for hypothesis for statistical testing. Critical t was the statistic technique used to test the hypotheses. The findings revealed that the selected reform policies in South Dakota appeared to assist students from the higher socioeconomic backgrounds to perform better than pupils from the lower socioeconomic backgrounds. The academic performance for the ethnic and social class minorities remained unchanged within the study timeline for reform. Examined from the prism of Michael Apple's critical theory, the selected South Dakota reform policies have paid little attention to the issues of social equality. Continuing and collective efforts to promote equitable reform policies for enhancing the learning experience of all children in South Dakota seem necessary.

    Introduction: We evaluated the impact of obesity on perioperative morbidity, functional, and oncological outcomes after radical perineal prostatectomy (RPP). Methods: A total of 298 consecutive patients underwent RPP at our institution. Patients were categorized into 3 groups based on their body mass index (BMI): Normal weight <25 kg/m2 (Group 1), overweight 25 to <30 kg/m2 (Group 2), and obese ≥30 kg/m2 (Group 3). We compared the groups with respect to perioperative data, postoperative oncologic, and functional outcomes. Evaluation of urinary continence and erectile function was performed using a patient-reported questionnaire and the International Index of Erectile Function-5 questionnaire, respectively, administered preoperatively and at 3, 6, and 12 months. Limitations included short follow-up time, retrospective design and lack of a morbidly obese group. Results: No significant differences were found among the 3 groups with regard to operative time, estimated blood loss, length of hospital stay, catheter removal time, positive surgical margin, and complication rates. At 12 months, 94.7%, 95% and 95% of normal, overweight and obese patients, respectively, were continent (free of pad use) (p = 0.81). At 12 months, 30.6%, 29.8% and 30.4% of patients had spontaneous erections and were able to penetrate and complete intercourse in Group 1, Group 2, and Group 3, respectively (p = 0.63). Conclusions: In this cohort of patients, no clinically relevant risks were associated with increasing BMI. PMID:26600881

    PubMed Central

    2011-01-01

    Background Relationships between improvements in lung function and other clinical outcomes in chronic obstructive pulmonary disease (COPD) are not documented extensively. We examined whether changes in trough forced expiratory volume in 1 second (FEV1) are correlated with changes in patient-reported outcomes. Methods Pooled data from three indacaterol studies (n = 3313) were analysed. Means and responder rates for outcomes including change from baseline in Transition Dyspnoea Index (TDI), St. George's Respiratory Questionnaire (SGRQ) scores (at 12, 26 and 52 weeks), and COPD exacerbation frequency (rate/year) were tabulated across categories of ΔFEV1. Also, generalised linear modelling was performed adjusting for covariates such as baseline severity and inhaled corticosteroid use. Results With increasing positive ΔFEV1, TDI and ΔSGRQ improved at all timepoints, exacerbation rate over the study duration declined (P < 0.001). Individual-level correlations were 0.03-0.18, but cohort-level correlations were 0.79-0.95. At 26 weeks, a 100 ml increase in FEV1 was associated with improved TDI (0.46 units), ΔSGRQ (1.3-1.9 points) and exacerbation rate (12% decrease). Overall, adjustments for baseline covariates had little impact on the relationship between ΔFEV1 and outcomes. Conclusions These results suggest that larger improvements in FEV1 are likely to be associated with larger patient-reported benefits across a range of clinical outcomes.

    Tracking and predicting motor outcomes is important in determining effective stroke rehabilitation strategies. Diffusion tensor imaging (DTI) allows for evaluation of the underlying structural integrity of brain white matter tracts and may serve as a potential biomarker for tracking and predicting motor recovery. In this study, we examined the longitudinal relationship between DTI measures of the posterior limb of the internal capsule (PLIC) and upper-limb motor outcomes in 13 stroke patients (median 20-month post-stroke) who completed up to 15 sessions of intervention using brain–computer interface (BCI) technology. Patients’ upper-limb motor outcomes and PLIC DTI measures including fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD) were assessed longitudinally at four time points: pre-, mid-, immediately post- and 1-month-post intervention. DTI measures and ratios of each DTI measure comparing the ipsilesional and contralesional PLIC were correlated with patients’ motor outcomes to examine the relationship between structural integrity of the PLIC and patients’ motor recovery. We found that lower diffusivity and higher FA values of the ipsilesional PLIC were significantly correlated with better upper-limb motor function. Baseline DTI ratios were significantly correlated with motor outcomes measured immediately post and 1-month-post BCI interventions. A few patients achieved improvements in motor recovery meeting the minimum clinically important difference (MCID). These findings suggest that upper-limb motor recovery in stroke patients receiving BCI interventions relates to the microstructural status of the PLIC. Lower diffusivity and higher FA measures of the ipsilesional PLIC contribute toward better motor recovery in the stroke-affected upper-limb. DTI-derived measures may be a clinically useful biomarker in tracking and predicting motor recovery in stroke patients receiving BCI interventions. PMID

    The assessment of real-world functional outcomes in clinical trials for medications targeting negative symptoms and cognitive impairment is extremely important. We tested the psychometric properties of the Daily Activity Report (DAR), a novel assessment of productive daily activity. We administered the DAR and additional assessments of functional outcome, functional capacity, cognition and symptomatology to 50 individuals with schizophrenia at 2 time points, 1 month apart and to 25 healthy controls. The DAR records a person's daily activity for 7 consecutive days based upon phone calls made 3 times a day. A total score and scores in 3 domains; instrumental activities (ie, independent living), social and work or school related activities are generated for the DAR. Inter-item consistency was high 0.89-0.94 for each domain and 0.88 overall. Test-retest reliability across 1 month for the total DAR score was 0.67,P< .0001. The total DAR score as well as scores for social activity and nondomestic work/school differed significantly between control and patient participants (P< .0001). DAR domain scores were associated with negative symptoms and functional outcomes, but the primary score related to these measures was the work/school dimension of the DAR. DAR scores were only weakly and nonsignificantly related to positive symptoms. This study provides preliminary support for the reliability and validity of the DAR using interviewer administration. The development of a patient reported version of the DAR using smart phone technology with automatic scoring is the next step. PMID:26712856

The DAR records a person’s daily activity for 7 consecutive days based upon phone calls made 3 times a day. A total score and scores in 3 domains; instrumental activities (ie, independent living), social and work or school related activities are generated for the DAR. Inter-item consistency was high 0.89–0.94 for each domain and 0.88 overall. Test–retest reliability across 1 month for the total DAR score was 0.67, P < .0001. The total DAR score as well as scores for social activity and nondomestic work/school differed significantly between control and patient participants (P < .0001). DAR domain scores were associated with negative symptoms and functional outcomes, but the primary score related to these measures was the work/school dimension of the DAR. DAR scores were only weakly and nonsignificantly related to positive symptoms. This study provides preliminary support for the reliability and validity of the DAR using interviewer administration. The development of a patient reported version of the DAR using smart phone technology with automatic scoring is the next step. PMID:26712856

    Objectives: Surgical management of small renal masses can be challenging in frail patients and thus modalities such as radiofrequency ablation (RFA) have emerged as valid alternative options. The aim of the current study was to present mid-term oncological and functional results on a series of patients with cT1a renal cell carcinomas (RCCs) who were unfit for surgery and underwent RFA using ultrasound guidance under local anesthesia. Methods: Data from patients fulfilling the study selection criteria were retrospectively collected. RENAL nephrometry score was used for tumor description. Parametric tests were used for data analysis and survival curves were estimated using the Kaplan–Meier method. Results: Overall, 32 patients (mean±standard deviation age, 72.4 ± 7.6 years) with biopsy-proven RCCs (tumor size, 23.75 ± 10.44 mm and RENAL score, 5.28 ± 1.33) underwent 32 RFA sessions. Twenty-seven patients (84.4%) had low complexity masses and five patients had masses of intermediate complexity (15.6%) according to RENAL score categorization. Over a follow-up period of 22.1 ± 13.7 months, one case of primary treatment failure was recognized (primary technical success 97.0%), and overall, three patients were diagnosed with residual disease (primary technique effectiveness 90.6%). No major complications occurred during the postprocedure 90-day follow up, while no difference was found in serum creatinine and estimated glomerular filtration rate pre and post procedure. Patients with intermediate-complexity renal lesions had shorter time to recurrence in comparison to low-complexity masses (p = 0.002). All patients were alive at the time of study data analysis without diagnosed metastases. Conclusions: Percutaneous RFA of small RCCs using ultrasound-based guidance under local anesthesia can be an effective alternative method for managing patients who are unfit for surgery.

    Introduction: Elderly patients are at risk of fracture nonunion, given the potential setting of osteopenia, poorer fracture biology, and comorbid medical conditions. Risk factors predicting fracture nonunion may compromise the success of fracture nonunion surgery. The purpose of this study was to investigate the effect of patient age on clinical and functional outcome following long bone fracture nonunion surgery. Materials and Methods: A retrospective analysis of prospectively collected data identified 288 patients (aged 18-91) who were indicated for long bone nonunion surgery. Two-hundred and seventy-two patients satisfied study inclusion criteria and analyses were performed comparing elderly patients aged ≥65 years (n = 48) with patients <65 years (n = 224) for postoperative wound complications, Short Musculoskeletal Functional Assessment (SMFA) functional status, healing, and surgical revision. Regression analyses were performed to look for associations between age, smoking status, and history of previous nonunion surgery with healing and functional outcome. Twelve-month follow-up was obtained on 91.5% (249 of 272) of patients. Results: Despite demographic differences in the aged population, including a predominance of medical comorbidities (P < .01) and osteopenia (P = .02), there was no statistical differences in the healing rate of elderly patients (95.8% vs 95.1%, P = .6) or time to union (6.2 ± 4.1 months vs. 7.2 ± 6.6, P = .3). Rates of postoperative wound complications and surgical revision did not statistically differ. Elderly patients reported similar levels of function up to 12 months after surgery. Regression analyses failed to show any significant association between age and final union or time to union. There was a strong positive association between smoking and history of previous nonunion surgery with time to union. Age was associated (positively) with 12-month SMFA activity score. Conclusions: Smoking and failure of previous surgical

    Cancer-related impairments result in disabilities similar to those typically encountered in inpatient rehabilitation settings; however, the use of rehabilitation services by cancer survivors is low. This is particularly important for older adults as they are at higher risk for cancer. This retrospective study collected data from medical records from 215 charts of patients admitted to an inpatient physical rehabilitation hospital, within a 5-year period, with a primary diagnosis of cancer. Mean age was 61 years (SD = 15.7) for 109 (51%) females and 106 (49%) males. Regardless of age, patients achieved significant functional improvement, as shown by their FIM scores (t = 23.06, p < .0001), from admission to discharge. The results have several important implications related to cancer survivorship among older adults. With a push toward aging in place, maintaining optimal physical functioning is crucial. Physical rehabilitation benefited the functional outcomes of this group of cancer survivors regardless of age. PMID:23908563

    Cognitive empathy impairments have been linked to poor social functioning in schizophrenia. However, prior studies primarily used self-reported empathy measures developed decades ago that are not well-aligned with contemporary models of empathy. We evaluated empathy and its relationship to social functioning in schizophrenia using the recently developed Questionnaire of Cognitive and Affective Empathy (QCAE). Schizophrenia (n=52) and healthy comparison (n=37) subjects completed the QCAE, Interpersonal Reactivity Index (IRI), and measures of neurocognition, symptoms, and social functioning. Between-group differences on the QCAE, and relationships between QCAE and IRI subscales, neurocognition, symptoms, and social functioning were examined. The schizophrenia group reported significantly lower cognitive empathy than comparison subjects, which was driven by low online simulation scores. Cognitive empathy explained significant variance in social functioning after accounting for neurocognition and symptoms. Group differences for affective empathy were variable; the schizophrenia group reported similar proximal responsivity, but elevated emotion contagion relative to comparison subjects. These findings bolster support for the presence and functional significance of impaired cognitive empathy in schizophrenia using a contemporary measure of empathy. Emerging evidence that some aspects of affective empathy may be unimpaired or hyper-responsive in schizophrenia and implications for the assessment and treatment of empathy in schizophrenia are discussed.

    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

    The assessment and management of tricuspid valve disease have evolved substantially during the past several years. Whereas tricuspid stenosis is uncommon, tricuspid regurgitation is frequently encountered and it is most often secondary due to annular dilatation and leaflet tethering from right ventricular remodelling. The indications for tricuspid valve surgery to treat tricuspid regurgitation are several and mainly related to the underlying disease, to the severity of insufficiency and to the right ventricular function. Surgical tricuspid repair has been avoided for years, because of the misleading concept that tricuspid regurgitation should disappear once the primary left-sided problem has been eliminated. Instead, during the last decade, many investigators have reported evidence in favor of a more aggressive surgical approach to functional tricuspid regurgitation, recognising the risk of progressive tricuspid insufficiency in patients with moderate or lesser degrees of tricuspid regurgitation and tricuspid annular dilatation. This concept, along with the long-term outcomes of principal surgical repair techniques are reported and discussed. Last, novel transcatheter therapies have begun to emerge for the treatment of severe tricuspid regurgitation in high-risk patients. Hence, very preliminary pre-clinical and clinical experiences are illustrated. The scope of this review is to explore the anatomic basis, the pathophysiology, the outcomes and the new insights in the management of functional tricuspid regurgitation. PMID:27329290

    The purpose of this study was to establish further the validity of the Behavioural Assessment of the Dysexecutive Syndrome (BADS) in a population with schizophrenia. Specific objectives were: to examine the construct validity and sensitivity of the BADS in differentiating between adult inpatients during an acute episode of illness, adult outpatients in the chronic stages of illness, and healthy controls; and to examine the predictive validity of the BADS regarding functional outcomes within the chronic group. Participants were 30 inpatients during an acute episode of their illness; 31 outpatients in the chronic stage; and 93 healthy controls. Instruments included the BADS, the Neurobehavioral Cognitive Status Examination (Cognistat) and the Routine Task Inventory (RTI). Significant differences in BADS scores were found between participants with schizophrenia and healthy controls, and between both groups of patients, showing the chronic group to have more deficits in executive functions. In addition, within the chronic group the BADS was found to be a significant predictor of two of the RTI outcome areas, instrumental activities of daily living (IADL) and communication, beyond that accounted for by basic cognitive skills. These results support the validity of the BADS within the schizophrenic population, and highlight the importance of measuring executive functions for rehabilitation. PMID:17454693

    Background: Dual plate fixation in comminuted bicondylar tibial plateau fractures remains controversial. Open reduction and internal fixation, specifically through compromised soft tissues, has historically been associated with major wound complications. Alternate methods of treatment have been described, each with its own merits and demerits. We performed a retrospective study to evaluate the functional outcome of lateral and medial plate fixation of Schatzker type V and VI fractures through an anterolateral approach, and a medial minimally invasive approach or a posteromedial approach. Materials and Methods: We treated 46 tibial plateau fractures Schatzker type V and VI with lateral and medial plates through an anterolateral approach and a medial minimal invasive approach over an 8 years period. Six patients were lost to followup. Radiographs in two planes were taken in all cases. Immediate postoperative radiographs were assessed for quality of reduction and fixation. The functional outcome was evaluated according to the Oxford Knee Score criteria on followup. Results: Forty patients (33 men and 7 women) who completed the followup were included in the study.
