BACKGROUND: Our previous study demonstrated that selective nerve root block (SNRB) can influence decision-making in lumbar surgery by guiding the selection of nerve roots targeted for decompression in diagnostic doubt patients (DDPs). However, further studies were needed to determine whether this selective decompression (SD) procedure would result in similar clinical outcomes and reduce the perioperative parameters and postoperative complications as compared to the non-selective decompression (NSD) procedure...

This study tested hypotheses drawn from a risk model positing that psychosocial risk plus disease-related and treatment factors contribute to bulimic symptoms in youth with type 1 diabetes (T1D) transitioning to an insulin pump. The goal of this study was to examine whether disease-related factors, particularly disease- and treatment-based disruption in hunger and satiety, contribute to report of bulimic symptoms in youth with T1D after accounting for psychosocial risk factors. 43 youth (ages 10-17, 54% female) with established T1D were recruited before transition from multiple daily injections to insulin-pump therapy from three tertiary pediatric diabetes centers...

Increasingly, the statistical and epidemiologic literature is turning its attention beyond issues of internal validity to questions of external validity. Here, we discuss some of the challenges of transporting a causal effect from a trial to a specific target population. We present an inverse odds weighting approach that can easily operationalize transportability. We derive these weights in closed form and illustrate their use with a simple numerical example. We discuss how the conditions required for the identification of internally valid causal effects are translated to apply to the identification of externally valid causal effects...

The main goal of cartilage repair is to create functional tissue by enhancing the in vitro conditions to more physiological in vivo conditions. Chondrogenic growth factors play an important role in influencing cartilage homeostasis. Insulin‑like growth factor (IGF)‑1 and transforming growth factor (TGF)‑β1 affect the expression of collagen type II (Col2) and glycosaminoglycans (GAGs) and, therefore, the targeted use of growth factors could make chondrogenic redifferentiation more efficient. In the present study, human chondrocytes were postmortally isolated from healthy articular cartilage and cultivated as monolayer or 3D pellet cultures either under normoxia or hypoxia and stimulated with IGF‑1 and/or TGF‑β1 to compare the impact of the different growth factors...

Gastrointestinal diseases are a significant health care and economic burden. Prevention and treatment of these diseases have been limited by the available human biologic models. Microphysiological systems comprise organ-specific human cultures that recapitulate many structural, biological, and functional properties of the organ in smaller scale including aspects of flow, shear stress and chemical gradients. The development of intestinal microphysiological system platforms represents a critical component in improving our understanding, prevention, and treatment of gastrointestinal diseases...

Control over the viscoelastic mechanical properties of hydrogels intended for use as biomedical materials has long been a goal of soft matter scientists. Recent research has shown that materials made from polymers with reversibly associating transient crosslinks are a promising strategy for controlling viscoelasticity in hydrogels, for example leading to systems with precisely tunable mechanical energy-dissipation. We and others have shown that bio-inspired histidine:transition metal ion complexes allow highly precise and tunable control over the viscoelastic properties of transient network hydrogels...

Atrial fibrillation (AF) usually manifests as reentrant circuits propagating through the whole atria creating chaotic activation patterns. Little is yet known about how differences in electrophysiological and ionic properties between patients modulate reentrant patterns in AF. The goal of this study is to quantify how variability in action potential duration (APD) at different stages of repolarization determines AF dynamics and their modulation by ionic block using a set of virtual whole-atria human models...

Raj Shah, Danielle Witt, Talal Asif, Fahad F Mir
Ipilimumab is a human monoclonal antibody that functions as a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor that is used to treat malignant melanoma. Due to ipilimumab's removal of immune regulation, specifically through the inactivation of CTLA-4, it is commonly associated with inflammatory and autoimmune events. Gastrointestinal (GI) related immune-related adverse events such as diarrhea occur in 29% of patients with 7.6% of patients specifically suffering from colitis. We describe a case of colonic perforation with ipilimumab use...

Increasing grain yield is the ultimate goal for maize breeding. High resolution quantitative trait loci (QTL) mapping can help us understand the molecular basis of phenotypic variation of yield and thus facilitate marker assisted breeding. The aim of this study is to use genotyping-by-sequencing (GBS) for large-scale SNP discovery and simultaneous genotyping of all F2 individuals from a cross between two varieties of maize that are in clear contrast in yield and related traits. A set of 199 F2 progeny derived from the cross of varieties SG-5 and SG-7 were generated and genotyped by GBS...

Sulzhan Bali, Jessica Taaffe
Both the Sustainable Development Goals (SDGs) and the Global Health Security Agenda (GHSA) represent bold initiatives to address systematically gaps in previous efforts to assure that societies can be resilient when confronted with potentially overwhelming threats to health. Despite their obvious differences, and differing criticisms of both, they shift away from vertical (problem- or disease-specific) to horizontal (comprehensive) solutions. Despite the comprehensiveness of the SDGs, they lack a specific target for global health security...

BACKGROUND: Influenza virus is responsible for substantial morbidity and mortality. Specific populations are at higher risk for exacerbations from influenza virus, such as patients with chronic obstructive pulmonary disease (COPD). Influenza vaccination coverage among COPD patients is low. Pharmacists can improve influenza vaccination among COPD patients by recognizing factors that influence vaccination and addressing these factors. OBJECTIVES: To (1) determine the recent influenza vaccination coverage among patients with COPD, (2) identify factors that were associated with immunization, and (3) interpret the results based upon Andersen's healthcare utilization model...

While the acquisition of knowledge about the sensory, emotional, and motor states of others has long been thought to derive from abstract inferential operations, recent theories based on neuroscientific and psychological models emphasize that motor simulation is essential to a variety of complex functions ranging from the monitoring of one's own performance to the understanding of others' actions, and matching self and others' states to optimize social interactions. In this review, we discuss evidence that simulating the actions of others has both bright and dark sides...

Drug eluting devices have greatly evolved during past years to become fundamental products of great marketing importance in the biomedical field. There is currently a large diversity of highly specialized devices for specific applications, making the development of these devices an exciting field of research. The replacement of the former bare metal devices by devices loaded with drugs allowed the sustained and controlled release of drugs, to achieve the desired local therapeutic concentration of drug. The newer devices have been "engineered" with surfaces containing micro- and nanoscale features in a well-controlled manner, that have shown to significantly affect cellular and subcellular function of various biological systems...

BACKGROUND: Systems of governance play a key role in the operation and performance of health systems. In the past six decades, China has made great advances in strengthening its health system, most notably in establishing a health insurance system that enables residents of rural areas to achieve access to essential services. Although there have been several studies of rural health insurance schemes, these have focused on coverage and service utilization, while much less attention has been given to the role of governance in designing and implementing these schemes...

A plethora of new development goals and funding institutions have greatly increased the demand for internationally comparable health estimates in recent years, and have brought important new players into the field of health estimate production. These changes have rekindled debates about the validity and legitimacy of global health estimates. This paper draws on country case studies and personal experience to support our opinion that the production and use of estimates are deeply embedded in specific social, economic, political and ideational contexts, which differ at different levels of the global health architecture...

BACKGROUND: Trachoma, a leading cause of blindness, is targeted for global elimination as a public health problem by 2020. In order to contribute to this goal, countries should demonstrate reduction of disease prevalence below specified thresholds, after implementation of the SAFE strategy in areas with defined endemicity. Zimbabwe had not yet generated data on trachoma endemicity and no specific interventions against trachoma have yet been implemented. METHODS: Two trachoma mapping phases were successively implemented in Zimbabwe, with eight districts included in each phase, in September 2014 and October 2015...

In this study the LCA methodology is applied in order to satisfy two goals: i) to evaluate the hot spots in site-specific production chain of biodiesel from terrestrial and micro-algae feedstock; ii) to compare quantitatively, utilizing primary data, the impacts of the first generation in respect to the third generation bio-fuels. Results show that micro-algae are neither competitive yet with traditional oil crops nor with fossil fuel. The use of renewable technologies as photovoltaics and biogas self production might increase the competitiveness of micro-algae oil...
