Chronic kidney disease affects ~10% of people worldwide and there are no disease modifying therapeutics that address the underlying cause of any form of kidney disease. Genome wide association studies have identified the G1 and G2 variants in the apolipoprotein L1 (APOL1) gene as major contributors to a subtype of proteinuric kidney disease now referred to as APOL1-mediated kidney disease (AMKD). We hypothesized that inhibition of APOL1 could have therapeutic potential for this genetically-defined form of kidney disease.

Exposure of lab animals to aeromedical evacuation relevant hypobaria after traumatic brain injury worsens neurological outcomes, which is paradoxically exacerbated by hyperoxia. This study tested the hypothesis that exposure of rats to hypobaria following cortical impact reduces cerebral blood flow, increases neuroinflammation, and alters brain neurochemistry.

While behavioral studies are a critical translational tool for evaluating neurologic function in disease models and toxicology studies, there is a lack of ferret-specific behavioral assays and corresponding data on baseline behavior. Play behavior is a promising target for evaluation of psychological well-being, particularly because ferrets engage in solitary and social play well into adulthood.

Time-dependent pharmacokinetics (TDPK) is a frequent confounding factor that misleads exposure-response (ER) analysis of therapeutic antibodies, where a decline in clearance results in increased drug exposure over time in patients who respond to therapy, causing a false-positive ER finding. The object of our simulation study was to explore the influence of clinical trial designs on the frequency of false-positive ER findings. Two previously published population PK models representative of slow- (pembrolizumab) and fast-onset (rituximab) TDPK were used to simulate virtual patient cohorts with time-dependent clearance and the frequency of false-positive ER findings.

One such manipulation is cytoplasmic incompatibility (CI), wherein the bacteria sabotage sperm in infected males to reduce the hatch rate when mated with uninfected females, but zygotes are 'rescued' when that male mates with an infected female. In the spider Mermessus fradeorum (Linyphiidae), Rickettsiella symbionts cause variable levels of CI.

Current EOS models that are applicable to liquids and supercritical fluids at liquid-like density under conditions relevant to planetary interiors and industrial processes are complex empirical models with many physically meaningless adjustable parameters. Here, we develop a generally applicable physics-based (GAP) EOS for liquids including supercritical fluids at liquid-like density.

Aim: To investigate if primary care records could be used to identify women at 'higher risk' of PNA.
Method: Mixed-methods approach using quantitative and qualitative methods.
Background: Perinatal anxiety (PNA) occurs during pregnancy and up to 12 months post-partum. PNA affects more than 21% of women and can impact adversely on mothers, children and their families. National Institute for Health and Care Excellence (NICE) guidance identified evidence gaps around non-pharmacological interventions for PNA.

These values are commonly referred to as performance-adjusted (pa) NEm (paNEm) and NEg (paNEg). The NEm and NEg of a diet can also be estimated by adding recovered energy (RE) with heat production (HP) derived from an automated head chamber system (AHCS), which we will term gas-adjusted (ga) NEm (gaNEm) and NEg (gaNEg).

This article about women's prison-based health care reports quantitative findings from surveying 206 female prisoners and qualitative findings from 45 female prisoners interviewed in one prison in Kansas and three prisons in Ohio. Respondents expressed concerns about the availability of quality prison health care and the timeliness of attention to requests for assistance. Additionally, respondents identified administrative barriers to receiving quality health care within each state.

To do so, it introduces the field of integrated assessment modeling, with a focus on the core economic methodology used by various types of models. It then summarizes some of the literature critiquing these models and how they inform policy.

Controlling the dynamics governing CoM motion is, therefore, critical for maintaining efficient and stable gait. However, how CoM dynamics change with ankle exoskeletons is unknown, and how to optimally model individual-specific CoM dynamics, especially in individuals with neurological injuries, remains a challenge.

Genetic metrics such as the frequency of polygenomic (multiple strain) infections, genetic clones, and the complexity of infection (COI, number of strains per infection) are correlated with transmission intensity. However, despite these correlations, it is unclear whether genetic metrics alone are sufficient to estimate clinical incidence.

The analysis is based on 1097 samples collected at health facilities during passive malaria case detection in 2019; it provides a baseline for analyzing parasite genetic metrics as they vary over time and geographic space. The study's goal was to identify genetic metrics that were informative about transmission intensity and other aspects of transmission dynamics, focusing on measures of genetic relatedness between parasites.

A 2 × 2, unbalanced experiment was conducted to determine the effectiveness of pre-harvest treatments applied to the pen surface for mitigation in cattle. Treatments included manure slurry intended to mimic pen run-off water (n = 4 pens), a bacteriophage cocktail (n = 4), a combination of both treatments (n = 5), and a control group (n = 5) that received no treatment.

We sought to qualitatively evaluate the patient experience of obtaining urethroplasty to better understand the impact of this experience on quality of life.

Strategic use of Plasmodium falciparum genetic variation has great potential to inform public health actions for malaria control and elimination. Malaria molecular surveillance (MMS) begins with a strategy to identify and collect parasite samples, guided by public-health priorities. In this review we discuss sampling design practices for MMS and point out epidemiological, biological, and statistical factors that need to be considered.
