The bacterial microbiome of the ant has been well characterized across body regions and maturation levels. However, potential effects of entomopathogens on the gut microbiome, and the fungal communities therein, are yet to be assessed. Additionally, the mycobiome remains often overlooked despite playing a vital role in gut ecology with potential implications for health and infection outcomes.

Background: Dose reduction of tyrosine kinase inhibitors (TKIs) is an option for some chronic myeloid leukemia (CML) patients to minimize side effects while maintaining efficacy. Shared decision-making (SDM) and patient decision aids (PDAs) are advocated to make informed choices such as reducing the dose of TKIs. This paper describes the development and alpha-testing of a PDA for patients with CML receiving TKI dose reduction.

Parasites have a rich and long natural history among biological entities, and it has been suggested that parasites are one of the most significant factors in the evolution of their hosts. However, it has been emphasized less frequently how co-evolution has undoubtedly also shaped the paths of parasites. It may seem safe to assume that specific differences among the array of potential hosts for particular parasites have restricted and diversified their evolutionary pathways and strategies for survival.

Article Synopsis
  • Parasites have evolved various strategies to manipulate host behavior to ensure their transmission, with notable instances seen in fungi, particularly through interactions with carpenter ants.
  • Recent research highlights the potential role of parasite-secreted proteins and light-driven biological rhythms in these manipulative relationships, suggesting a complex infection and manipulation biology.
  • The review aims to explore whether the mechanisms behind these manipulative behaviors are unique to specific parasites or have evolved independently across different taxa, and it proposes hypotheses for future research on this topic.

Background: Minimizing medication waste through the redispensing of oral anticancer drugs (OADs) that were unused by patients provides economic and environmental benefits, but this is not yet universally implemented in clinical care.

Objectives: To identify barriers and facilitators to the implementation of redispensing unused OADs in clinical care.

Methods: A multicentre intervention study following a hybrid effectiveness-implementation type I design was conducted, consisting of semi-structured interviews with key stakeholders involved in the redispensing program: pharmacy employees, prescribing clinicians in oncology and haematology, patients who participated in redispensing and patients who declined trial participation.

California faces several serious direct and indirect climate exposures that can adversely affect public health, some of which are already occurring. The public health burden now and in the future will depend on atmospheric greenhouse gas concentrations, underlying population vulnerabilities, and adaptation efforts. Here, we present a structured review of recent literature to examine the leading climate risks to public health in California, including extreme heat, extreme precipitation, wildfires, air pollution, and infectious diseases.

Introduction: Children with underlying comorbidities and infants are most severely affected by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, including in low- and middle-income countries with a high prevalence of HIV and TB. We describe the clinical presentation of SARS-CoV-2 infection in children during the Omicron wave, in Cape Town, South Africa.

Methods: We analysed routine care data from a prospective cohort of children aged 0-13 years, with a positive SARS-CoV-2 real-time reverse-transcription polymerase chain reaction (rRT-PCR) or SARS-CoV-2 antigen test, admitted to Tygerberg Hospital between 1 November 2021 until 1 March 2022.

In California, wildfire risk and severity have grown substantially in the last several decades. Research has characterized extensive adverse health impacts from exposure to wildfire-attributable fine particulate matter (PM), but few studies have quantified long-term outcomes, and none have used a wildfire-specific chronic dose-response mortality coefficient. Here, we quantified the mortality burden for PM exposure from California fires from 2008 to 2018 using Community Multiscale Air Quality modeling system wildland fire PM estimates.

Background: The mosquito microbiome is an important modulator of vector competence and vectoral capacity. Unlike the extensively studied bacterial microbiome, fungal communities in the mosquito microbiome (the mycobiome) remain largely unexplored. To work towards getting an improved understanding of the fungi associated with mosquitoes, we sequenced the mycobiome of three field-collected and laboratory-reared mosquito species (Aedes albopictus, Aedes aegypti, and Culex quinquefasciatus).

Objectives: Biological disease-modifying antirheumatic drugs (bDMARDs) require specific storage temperatures, but are frequently stored outside the recommended range of 2-8°C. As incorrect storage may affect therapy effectiveness and consequently lead to higher disease activity, compliance with recommended storage temperatures should be improved. eHealth interventions can provide insight into storage temperatures and alerts in case of deviations from recommended temperatures.

Camponotus floridanus ants show altered behaviors followed by a fatal summiting phenotype when infected with manipulating Ophiocordyceps camponoti-floridani fungi. Host summiting as a strategy to increase transmission is also observed with parasite taxa beyond fungi, including aquatic and terrestrial helminths and baculoviruses. The drastic phenotypic changes can sometimes reflect significant molecular changes in gene expression and metabolite concentrations measured in manipulated hosts.
