Development and confirmation of humanized plasma and epithelial lining fluid exposures of meropenem, cefiderocol and tobramycin in a standardized neutropenic murine pneumonia model.

Background: Murine pneumonia models play a fundamental role in the preclinical development of novel compounds seeking an indication for the treatment of pneumonia. It is vital that plasma exposures in these models are not used as a surrogate for exposure in pulmonary epithelial lining fluid (ELF). Herein, human-simulated regimens (HSRs) in both plasma and ELF of meropenem, cefiderocol and tobramycin are described in the standardized COMBINE murine neutropenic pneumonia model.

Assessment of Women's Discretionary Salt Intake and Household Salt Utilization in Preparation for a Salt Fortification Trial in Oromia Region, Ethiopia.

There is a high incidence of neural tube defects (NTDs) in Ethiopia and folate insufficiency, a primary risk factor for NTDs, is common among Ethiopian women of reproductive age (WRA). Folic acid fortification of salt has been proposed as a strategy to control these problems. In preparation for an intervention trial to assess the nutritional effects of folic acid-fortified salt, we measured discretionary salt intakes among nonpregnant WRA using observed weighed food records, and we assessed household salt disappearance rates.

Unraveling the impact of drought on waterbird community assembly and conservation strategies.

Drought-induced changes in lakes and wetlands, crucial habitats for migratory waterbirds, can greatly affect their foraging and habitat utilization. These changes lead to a decline in waterbird species richness and may cause shifts in community assembly from phylogenetic and functional trait perspectives. However, a gap remains between ecological mechanistic research about these changes and conservation applications.

Caregiver Feeding Behaviours and Child Dietary Diversity and Growth in Rural Bangladesh.

This study examined relations between caregiver feeding behaviours, child dietary diversity and anthropometry at 24 months of age in rural Bangladesh. Twenty-four hours dietary recall, weight and length data were collected on 4733 children. Factor analysis was applied to an 11-item caregiver feeding behaviours scale administered at 24 months, revealing two constructs: responsive/involved (five items) and forceful (six items); each dichotomised to reflect low and high use.

Toward person-centred measures of contraceptive demand: a systematic review of the relationship between intentions to use and actual use of contraception.

Background: Understanding people's interest in using modern contraception is critical to ensuring programs align with people's preferences and needs. Current measures of demand for contraception are misinterpreted. More direct measures of intention to use (ITU) contraception do exist but remain underexplored.

Generative language models exhibit social identity biases.

Social identity biases, particularly the tendency to favor one's own group (ingroup solidarity) and derogate other groups (outgroup hostility), are deeply rooted in human psychology and social behavior. However, it is unknown if such biases are also present in artificial intelligence systems. Here we show that large language models (LLMs) exhibit patterns of social identity bias, similarly to humans.

Reframing assisted dying through the civil law: possibilities and challenges for the UK.

Background: Current proposals for assisted dying in the UK are based on embedding it within a medical, healthcare model. This model is revealing challenges in safeguarding, monitoring and the impact on healthcare.

Objective: To explore if a different model is a safer, pragmatic and realistic alternative.

Background: Multiple broadly neutralising monoclonal antibodies (mAbs) are in development for HIV-1 prevention. The aim of this trial was to test the PGT121.414.

Molecular features of the serological IgG repertoire elicited by egg-based, cell-based, or recombinant haemagglutinin-based seasonal influenza vaccines: a comparative, prospective, observational cohort study.

Background: Egg-based inactivated quadrivalent seasonal influenza vaccine (eIIV4), cell culture-based inactivated quadrivalent seasonal influenza vaccine (ccIIV4), and recombinant haemagglutinin (HA)-based quadrivalent seasonal influenza vaccine (RIV4) have been licensed for use in the USA. In this study, we used antigen-specific serum proteomics analysis to assess how the molecular composition and qualities of the serological antibody repertoires differ after seasonal influenza immunisation by each of the three vaccines and how different vaccination platforms affect the HA binding affinity and breadth of the serum antibodies that comprise the polyclonal response.

Methods: In this comparative, prospective, observational cohort study, we included female US health-care personnel (mean age 47·6 years [SD 8]) who received a single dose of RIV4, eIIV4, or ccIIV4 during the 2018-19 influenza season at Baylor Scott & White Health (Temple, TX, USA).

Using knowledge translation to support the use of evaluation findings: A case study of the linda mama free maternity program in Kenya.

Using program evaluation findings is crucial in improving health programs and realising the program's benefits. In this article, we report on how a knowledge translation (KT) approach supported the use of evaluation findings to improve the Linda Mama free maternity program in Kenya. We used a case study design employing qualitative approaches to describe our KT strategy and its impact on evaluation use.

Immunogenicity and safety following a homologous booster dose of a SARS-CoV-2 recombinant spike protein vaccine with Matrix-M adjuvant (NVX-CoV2373) versus a primary series in people living with and without HIV-1 infection in South Africa: A randomized crossover phase 2a/2b trial.

COVID-19 remains a global public health issue and an improved understanding of vaccine performance in immunocompromised individuals, including people living with HIV (PLWH), is needed. Initial data from the present study's pre-crossover/booster phase were previously reported. This phase 2a/b clinical trial in South Africa (2019nCoV-501/NCT04533399) revisits 1:1 randomly assigned HIV-negative adults (18-84 years) and medically stable PLWH (18-64 years) who previously received two NVX-CoV2373 doses (5 μg recombinant Spike protein with 50 μg Matrix-M™ adjuvant) or placebo.

Mortality Among Severely Injured Adolescents Admitted to Pediatric vs Adult Trauma Centers.
