Population genetics and molecular xenomonitoring of Biomphalaria freshwater snails along the southern shoreline of Lake Malawi, Malawi.

Background: Intestinal schistosomiasis was confirmed endemic in Mangochi District, Malawi, in May of 2018 following an unexpected encounter with discreet populations of Biomphalaria spp. freshwater snails during routine malacological surveillance activities. Since then, only limited malacological surveillance of Biomphalaria has been carried out, and so the distribution of Biomphalaria populations in this area is currently unclear.

A geospatial analysis of local intermediate snail host distributions provides insight into schistosomiasis risk within under-sampled areas of southern Lake Malawi.

Background: Along the southern shoreline of Lake Malawi, the incidence of schistosomiasis is increasing with snails of the genera Bulinus and Biomphalaria transmitting urogenital and intestinal schistosomiasis, respectively. Since the underlying distribution of snails is partially known, often being focal, developing pragmatic spatial models that interpolate snail information across under-sampled regions is required to understand and assess current and future risk of schistosomiasis.

Methods: A secondary geospatial analysis of recently collected malacological and environmental survey data was undertaken.

Athletic Trainer and Emergency Medical Technician or Paramedic Opinions of Each Other's Understanding of Essential Emergent Football Injury Situation Tasks.

Objective: Improving the role understanding between essential emergency healthcare providers may improve teamwork and efficacy. This study asked licensed athletic trainers (ATs) and emergency medical technicians (EMTs) or paramedics for their opinions of the others' understanding of essential tasks in an emergent football injury situation. The hypothesis was that groups would have differing opinions.

Modelling the age-prevalence relationship in schistosomiasis: A secondary data analysis of school-aged-children in Mangochi District, Lake Malawi.

Schistosomiasis is an aquatic snail borne parasitic disease, with intestinal schistosomiasis (IS) and urogenital schistosomiasis (UGS) caused by and infections, respectively. School-aged-children (SAC) are a known vulnerable group and can also suffer from co-infections. Along the shoreline of Lake Malawi a newly emerging outbreak of IS is occurring with increasing UGS co-infection rates.

Contribution of Inhibitory Metabolites and Competition for Nutrients to Colonization Resistance against by Commensal .

is an anaerobic pathogen that causes significant morbidity and mortality. Understanding the mechanisms of colonization resistance against is important for elucidating the mechanisms by which is able to colonize the gut after antibiotics. Commensal play a key role in colonization resistance.

Assessment of a Hotel-Based COVID-19 Isolation and Quarantine Strategy for Persons Experiencing Homelessness.

Importance: Several jurisdictions in the United States have secured hotels to temporarily house people experiencing homelessness who require isolation or quarantine for confirmed or suspected coronavirus disease 2019 (COVID-19). To our knowledge, little is known about how these programs serve this vulnerable population outside the hospital setting.

Objective: To assess the safety of a hotel-based isolation and quarantine (I/Q) care system and its association with inpatient hospital capacity.

Microstructure dependent filament forming kinetics in HfO2 programmable metallization cells.

Variability remains the principal concern for commercialization of HfO2 based resistance switching devices. Here, we investigate the role of thermal processing conditions on internal structure of atomic layer deposited HfO2 thin films, and the impact of that structure on filament forming kinetics of p+ Si/HfO2/Cu and TiN/HfO2/Cu devices. Regardless of bias polarity or electrode metal, filament formation times are at least one order of magnitude shorter in polycrystalline than in amorphous films, which we attribute to the presence of fast ion migration along grain boundaries.
