OBJECTIVES: To assess a comprehensive package of ultrasound quality control in a large multicentre study of fetal growth - the Fetal Growth Longitudinal Study of the INTERGROWTH-21(st) Project. METHODS: We performed quality control (QC) measures on 20,313 ultrasound scan images taken prospectively from 4,321 fetuses at 14-41 weeks' gestation in eight geographical locations. At the time of each ultrasound examination, three fetal biometric variables were measured in triplicate on separately generated images: head circumference (HC), abdominal circumference (AC) and femur length (FL)...

Weight loss is a common symptom of Parkinson's disease and is associated with impaired quality of life. Predictors of weight loss have not been studied in large clinical cohorts. We previously observed an association between change in body mass index and change in Unified Parkinson's Disease Rating Scale (UPDRS) motor and total scores. In this study, we performed a secondary analysis of longitudinal data (1-6 years) from 1619 participants in the NINDS Exploratory Trials in PD Long-term Study-1 (NET-PD LS1) to explore predictors of weight loss in a large prospective clinical trial cohort of early treated Parkinson's disease...

PURPOSE: Colorectal cancer (CRC) screening is effective in finding early stage CRC and dramatically improves survival rates. Despite this, the number of eligible patients who do not obtain CRC screening is unacceptably high. METHODS: We conducted a longitudinal, randomized controlled trial investigating the utility of a blood-based protein assay on the quality of care delivered by practicing PCPs in the United States. We used standardized simulated patients (CPVs), presenting with symptoms suggestive of a higher likelihood of CRC, to measure how frequently these PCPs ordered diagnostic colonoscopy...

Context Endocrine-metabolic disease (EMD) risk following spinal cord injury (SCI) is associated with significant multi-morbidity (i.e. fracture, diabetes, heart disease), mortality, and economic burden. It is unclear to what extent rehabilitation interventions can modify EMD risk and improve health status in community-dwelling adults with chronic SCI. Objectives To characterize rehabilitation interventions and summarize evidence on their efficacy/effectiveness to modify precursors to EMD risk in community-dwelling adults with chronic SCI...

BACKGROUND: Many studies have examined the mental health of carers of people with dementia. Few have examined their experiences in the advanced stages of disease and into bereavement. We aimed to understand the experiences of carers during advanced dementia exploring the links between mental health and experiences of end of life care. METHODS: Mixed methods longitudinal cohort study. Thirty-five family carers of people with advanced dementia (6 at home, 29 in care homes) were recruited and assessed monthly for up to nine months or until the person with dementia died, then at two and seven months into bereavement...

Available data indicate that there are gender differences in many features of Parkinson's disease (PD). Precise identification of the gender differences is important to tailor treatment, predict outcomes, and meet other individual and social needs in women and men with PD. The aim of this study was to review the available clinical data on gender differences in PD. Original articles and meta-analyses published between 1990 and 2016 systematically exploring gender differences in PD were reviewed. There is slight male preponderance in incidence and prevalence of PD...

OBJECTIVES: Decision-making around the use of thrombolysis for patients with intermediate-risk (submassive) PE remains challenging. Studies indicate favorable clinical outcomes with systemic thrombolytics (IV tPA), but the risk of major bleeding and hemorrhagic stroke is a deterrent. Catheter-directed thrombolysis (CDT) may be a preferable strategy, as it has been shown to have a lower risk of bleeding than systemic thrombolysis. However, a three-arm randomized control study comparing IV tPA, CDT, and anticoagulation alone, with long-term follow up, would be costly and is unlikely to be performed...

STUDY OBJECTIVE: We assess whether the expansion of Medicaid under the Patient Protection and Affordable Care Act (ACA) results in changes in emergency department (ED) visits or ED payer mix. We also test whether the size of the change in ED visits depends on the change in the size of the Medicaid population. METHODS: Using all-capture, longitudinal, state data from the Agency for Healthcare Research and Quality's Fast Stats program, we implemented a difference-in-difference analysis, which compared changes in ED visits per capita and the share of ED visits by payer (Medicaid, uninsured, and private insurance) in 14 states that did and 11 states that did not expand Medicaid in 2014...

This study examined the long-term predictors of social support satisfaction among HIV-positive young Black men who have sex with men (YBMSM). Data were collected across three waves between October 2012 and November 2014 as part of the baseline assessment from Project nGage, a preliminary efficacy randomized control study examining the role of social support in improving HIV care among YBMSM. The sample included 92 YBMSM aged 18-29. Major results controlling for age, education and intervention effects indicated that psychological health, social network size, and education at baseline predicted differences in social support satisfaction at Wave 3, with no significant effects based on length of HIV diagnosis...

Depression treatment has been proven to relieve depressive symptoms and pain and may therefore improve the health-related quality of life (HRQoL) among adults with arthritis. The objective of the current study was to examine the HRQoL associated with depression treatment among adults with arthritis and depression. A retrospective longitudinal cohort study design using data from the Medical Expenditure Panel Survey (2009-2012) was adopted. The study sample consisted of adults (≥ 21 years) with co-existing arthritis and depression (N = 1692)...

INTRODUCTION: Ankle fracture surgery is a common procedure, but the influence of anaesthesia choice on postoperative pain and quality of recovery is poorly understood. Some authors suggest a benefit of peripheral nerve block (PNB) in elective procedures, but the different pain profile following acute fracture surgery and the rebound pain on cessation of the PNB both remain unexplored. We present an ongoing randomised study aiming to compare primary PNB anaesthesia with spinal anaesthesia for ankle fracture surgery regarding postoperative pain profiles and quality of recovery...
