Adherence to antiretroviral therapy (ART) is an important determinant of clinical success assessed in many HIV studies. Harmonizing adherence data from studies that use different measures is difficult without a co-calibration equation to convert between validated instruments. Our purpose was to co-calibrate two commonly used adherence measures: the AIDS Clinical Trials Group (ACTG) questionnaire and the Visual Analog Scale (VAS). We used robust linear regression to develop a co-calibration equation in a clinical care cohort...

Real-time energy measurement using pulse integration method for high repetition rate ultrashort laser pulses based on FPGA (Field-Programmable Gate Array) and high-speed pipeline ADC (Analog-to-Digital Convertor) is introduced in this paper. There are two parts contained in this method: pulse integration and real-time data processing. The pulse integration circuit will convert the pulse to the step type signals which are linear to the laser pulse energy. Through the real-time data processing part, the amplitude of the step signals will be obtained by ADC sampling and conducting calculation in real time in FPGA...

Randomized controlled trials (RCTs) aim at providing reliable estimates of treatment benefit. Missing data and nonadherence to treatment are distinct problems that can substantially impede this task. In practice, the fact that the handling of missing data due to nonadherence affects the question that is addressed is often ignored. Estimands allow precisely predefining the question of interest. Estimands are definitions of that which is being estimated with regard to population, endpoint, and handling of postrandomization events (eg, nonadherence)...

Due to addition of anti-CD20 to anthracycline-based chemotherapy, survival of diffuse large B-cell lymphoma increased during the last decade. Although these trends are encouraging, there are still persistent differences in survival within and between US and European countries suggesting the role of non-biological factors. Our aim was to investigate the influence of such factors on relative survival of diffuse large B-cell lymphoma patients. We conducted a retrospective multicenter registry-based study in France, between 2002 and 2008, on 1165 incident cases of diffuse large B-cell lymphoma Relative survival analyses were performed and data missing were controlled with multiple imputation method...

Fibrodysplasia Ossificans Progressiva (FOP) is a rare inherited disease characterized by progressive heterotopic ossification. Disease onset, severity and symptoms vary between FOP patients, as does the frequency and activity of so-called flare-ups, during which tendons, ligaments, muscle and soft tissue are replaced by bone. Traumata, infections or other stressors are known inducers of flare-ups, and the hormone Activin A may be involved in disease activity; however, reliable biomarkers for FOP activity are missing, and the basal trace element and inflammatory state of patients are unknown...

Patients undergoing coronary angiography for suspected coronary heart disease who are found to have coronary atherosclerotic disease with <50% diameter stenosis may carry a risk of adverse cardiac events similar to that in patients with single-vessel obstructive disease. Yet clinical practice guidelines offer no direction for managing symptomatic patients with nonobstructive coronary atherosclerosis because current diagnostic criteria for coronary heart disease are not met. Accordingly, secondary preventive measures are not endorsed, and their role is not defined in this setting...

Hyperprolactinemia and prolactinomas cause infertility in significant number of women. But, pregnancy may lead to post-partum remission of hyperprolactinemia. The data on pregnancy and tumor outcome in women with macroprolactinoma conceiving on Cabergoline (CAB) therapy is increasing but still less than with Bromocriptine. We studied the incidence of fetal malformations, hyperprolactinemia and tumor course after gestation in infertile women harboring macroprolactinoma, who conceived on CAB therapy during the year 2005-2015...

STUDY QUESTION: What is the degree of intrinsic insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) and the relative contribution of BMI to overall IR based on meta-analysis of gold standard insulin clamp studies? SUMMARY ANSWER: We report an inherent reduction (-27%) of insulin sensitivity (IS) in PCOS patients, which was independent of BMI. WHAT IS ALREADY KNOWN: PCOS is prevalent, complex and underpinned by IR but controversies surround the degree of intrinsic IR in PCOS, the effect of BMI and the impact of the different diagnostic criteria (NIH versus Rotterdam) in PCOS...

BACKGROUND: To optimise care HIV patients need to be promptly initiated on antiretroviral therapy (ART) and subsequently retained on treatment. In this study we report on the interval between enrolment and treatment initiation, and investigate subsequent attrition and mortality of patients on ART at a rural clinic in Malawi. METHODS: HIV-positive individuals were recruited to a cohort study between January 2008 and August 2011 at Chilumba Rural Hospital (CRH). Outcomes were ascertained, up to 7 years after enrolment, through follow-up and by linkage to ART registers and the Karonga Health and Demographic Surveillance System (KHDSS)...

BACKGROUND: Mortality data are affected by miscertification of the medical cause of death deaths and changes to cause of death classification systems. We present both mappings of ICD9 and ICD10 to a unified list of causes, and a new statistical model for reducing the impact of misclassification of cause of death. METHODS: We propose a Bayesian mixed-effects multinomial logistic model that can be run on individual record level death certificates to reclassify "garbage-coded" deaths onto causes that are more meaningful for public health purposes...

BACKGROUND: The importance of process evaluations in examining how and why interventions are (un) successful is increasingly recognized. Process evaluations mainly studied the implementation process and the quality of the implementation (fidelity). However, in adopting this approach for participatory organizational level occupational health interventions, important aspects such as context and participants perceptions are missing. Our objective was to systematically describe the implementation process of a participatory organizational level occupational health intervention aimed at reducing work stress and increasing vitality in two schools by applying a framework that covers aspects of the intervention and its implementation as well as the context and participants perceptions...

Link weights are essential to network functionality, so weight prediction is important for understanding weighted networks given incomplete real-world data. In this work, we develop a novel method for weight prediction based on the local network structure, namely, the set of neighbors of each node. The performance of this method is validated in two cases. In the first case, some links are missing altogether along with their weights, while in the second case all links are known and weight information is missing for some links...

BACKGROUND: Biotin-thiamine-responsive basal ganglia disease (BTBGD) is an autosomal recessive neurometabolic disorder caused by mutations in the SLC19A3 gene. The disease is characterized by subacute encephalopathy with confusion, dysphagia, dysarthria, and seizures. METHODS: We diagnosed a family affected by BTBGD and studied them including prognosis of cases when diagnosed and treated early in the disease process. We also review the literature comprehensively and summarize all published data about this disorder...

BACKGROUND: Formulary management is a key component to ensuring the safe, effective, and fiscally responsible use of medications for health systems. One challenge in the formulary management process is making the most relevant formulary information easily accessible to practitioners involved in medication therapy decisions at the point of care. In September 2014, Froedtert and the Medical College of Wisconsin (F&MCW) implemented a commercial formulary management tool (CFMT) to improve accessibility to the recently aligned health-system formulary...

Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the 'big four' that includes Cobra, Krait, Russel's viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e...

Gene-environment interaction (G×E) refers to the phenomenon that the same mutation has different phenotypic effects in different environments. Although quantitative trait loci (QTLs) exhibiting G×E have been reported, little is known about the general properties of G×E and those of its underlying QTLs. Here we use the genotypes of 1005 segregants from a cross between two Saccharomyces cerevisiae strains and the growth rates of these segregants in 47 environments to identify growth rate QTLs (gQTLs) in each environment and QTLs that have different growth effects in each pair of environments (g×eQTLs)...

Self-reporting is a well-established approach within the medical and psychological sciences. In order to avoid recall bias, i.e. past events being remembered inaccurately, the reports can be filled out on a smartphone in real-time and in the natural environment. This is often referred to as ambulatory assessment and the reports are usually triggered at regular time intervals. With this sampling scheme, however, rare events (e.g. a visit to a park or recreation area) are likely to be missed. When addressing the correlation between mood and the environment, it may therefore be beneficial to include participant locations within the ambulatory assessment sampling scheme...
