Use of vasopressors in patients with acute kidney injury on continuous kidney replacement therapy.

Objective: To investigate whether the use of a specific vasopressor was associated with increased mortality or adverse outcomes in patients with acute kidney injury (AKI) receiving continuous kidney replacement therapy (CKRT).

Methods: Patients with AKI who underwent CKRT between 1/1/2012-1/1/2021 at a tertiary academic hospital were included. Cox proportional hazard model was used to assess the relationship between time-dependent vasopressor dose and in-hospital mortality.

Impact of dosing schedules on performance of rotavirus vaccines in Ghana.

There is currently limited evidence regarding how the rotavirus vaccine dosing schedule might be adjusted to improve vaccine performance. We quantified the impact of the previously implemented 6/10-week Rotarix vaccine (RV1) in Ghana to the model-predicted impact for other vaccine dosing schedules across three hospitals and the entire country. Compared to no vaccination, the model-estimated median percentage reductions in rotavirus ranged from 28 to 85% and 12 to 71% among children <1 and <5 years old, respectively.

Hysteresis in the transfer characteristics of MoS field effect transistors: gas, temperature and photo-irradiation effect.

We report the characteristic behaviors of the hysteresis observed in the transfer characteristics of back-gated field-effect transistors with an exfoliated MoS channel under various conditions. We find that the hysteresis is strongly enhanced by temperature, environmental gas, or light irradiation. Our measurements reveal the characteristic hysteresis behaviors in a 1 atm oxygen environment, which we explain as an oxygen molecule facilitated charge acceptor on the MoS surface.

Influence of herbal supplementation on nutrient digestibility, blood biomarkers, milk yield, and quality in tropical crossbred cows.

Herbal supplements containing diverse phytochemicals have been proven to improve digestibility, beneficial serum metabolites, milk yield, and quality in cows. However, the temperature sensitivity of phytochemicals in herbs complicates their practical use as livestock supplements. In response, this study aimed to assess how shade-dried plantain, lemongrass, and their combination influence cow performance, digestibility, serum and milk antioxidants, and milk fatty acids.
