A framework for managing infectious diseases in rural areas in low- and middle-income countries in the face of climate change-East Africa as a case study.

Climate change is having unprecedented impacts on human health, including increasing infectious disease risk. Despite this, health systems across the world are currently not prepared for novel disease scenarios anticipated with climate change. While the need for health systems to develop climate change adaptation strategies has been stressed in the past, there is no clear consensus on how this can be achieved, especially in rural areas in low- and middle-income countries that experience high disease burdens and climate change impacts simultaneously.

Oxidation state of bioavailable dissolved organic matter influences bacterioplankton respiration and growth efficiency.

Oxygen consumption by oceanic microbes can predict respiration (CO production) but requires an assumed respiratory quotient (RQ; ΔO/ΔCO). Measured apparent RQs (ARQs) can be impacted by various processes, including nitrification and changes in dissolved organic matter (DOM) composition, leading to discrepancies between ARQ and actual RQ. In DOM remineralization experiments conducted in the eastern North Atlantic Ocean, ARQs averaged 1.

The WHO Disease Outbreak News during the Covid-19 pandemic.

During the Covid-19 pandemic, the World Health Organization (WHO) was an important public source of information - not only about the pandemic, but also thousands of other potential health emergencies. Here, we examine the 242 reports published in the WHO Disease Outbreak News (DON) during the first four years of the Covid-19 pandemic (2020 to 2023), and document the diseases and regions that were reported. We find that multinational epidemics of diseases like Ebola virus and MERS-CoV continue to dominate the DON.

Microbial carbon oxidation in seawater below the hypoxic threshold.

Global oxygen minimum zones (OMZs) often reach hypoxia but seldom reach anoxia. Recently it was reported that Michaelis Menten constants (K) of oxidative enzymes are orders of magnitude higher than respiratory K values, and in the Hypoxic Barrier Hypothesis it was proposed that, in ecosystems experiencing falling oxygen, oxygenase enzyme activities become oxygen-limited long before respiration. We conducted a mesocosm experiment with a phytoplankton bloom as an organic carbon source and controlled dissolved oxygen (DO) concentrations in the dark to determine whether hypoxia slows carbon oxidation and oxygen decline.

A comparative analysis of dengue, chikungunya, and Zika manifestations in a pediatric cohort over 18 years.

Background: Dengue, chikungunya, and Zika are mosquito-borne diseases of major human concern. Differential diagnosis is complicated in children and adolescents by their overlapping clinical features (signs, symptoms, and complete blood count results). Few studies have directly compared the three diseases.
