Arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota) are essential to plant community diversity and ecosystem functioning. However, increasing human land use represents a major threat to native AMF globally. Characterizing the loss of AMF diversity remains challenging because many taxa are undescribed, resulting in poor documentation of their biogeography and family-level disturbance sensitivity.

Background: Members of the Anopheles gambiae complex are major malaria vectors in sub-Saharan Africa. Their larval stages inhabit a variety of aquatic habitats in which, under natural circumstances, they are preyed upon by different taxa of aquatic macroinvertebrate predators. Understanding the potential impact of predators on malaria vector larval population dynamics is important for enabling integrated local mosquito control programmes with a stronger emphasis on biocontrol approaches.

Serum Pentosidine in Relation to Obesity in Patients with Type 2 Diabetes and Healthy Controls.

Calcif Tissue Int

January 2025

Division of Endocrinology, Diabetes and Metabolism, University Hospital Basel, Aeschenvorstadt 57, 4051, Basel, Switzerland.

Pentosidine (PEN), a surrogate marker of advanced glycation end-product formation, reflects increased non-enzymatic cross-linking in bone collagen, which is thought to be an important determinant of bone fragility in type 2 diabetes mellitus (T2DM). We aimed to investigate serum concentrations of PEN in patients with T2DM and controls without T2DM and to examine its relationship with bone parameters and metabolic state such as glycaemic control, insulin resistance and body weight. In a cross-sectional study-design, data from postmenopausal women and men with T2DM (n = 110) and controls without T2DM (n = 111) were evaluated.

Background: Measuring neurocognitive functioning in children requires validated, age-appropriate instruments that are adapted to the local cultural and linguistic context. We sought to evaluate the usability and psychometric properties of five tools that assess general intelligence, executive functioning, and sustained attention among Tanzanian children.

Methods: We adapted five age-appropriate neurocognitive assessment batteries from previously published assessment materials to the Tanzanian context.

Assessment of Favipiravir and Remdesivir in Combination for SARS-CoV-2 Infection in Syrian Golden Hamsters.

Viruses

November 2024

Department of Pharmacology and Therapeutics, Institute of Systems, Molecular and Integrative Biology, University of Liverpool, Liverpool L69 3BX, UK.

Favipiravir (FVP) and remdesivir (RDV) have demonstrable antiviral activity against SARS-CoV-2. Here, the efficacy of FVP, RDV, and FVP with RDV (FVP + RDV) in combination was assessed in Syrian golden hamsters challenged with SARS-CoV- 2 (B.1.

Background: Persistent inequities in access to vaccinations pose challenges for immunization programs worldwide. Innovations facilitating vaccine delivery, such as leveraging vaccine thermostability through a Controlled Temperature Chain (CTC), have emerged as a potential solution to increase coverage in low- and middle-income countries (LMICs) countries such as Côte d'Ivoire, reducing dependence on the cold chain and improving vaccine delivery efficiency. However, the added value of thermostable vaccines and their integration into national immunization programs is under-recognized by stakeholders.

The treatment of infective endocarditis (IE) is based on long intravenous administration of antibiotics. This is still a hard-to-die dogma. Throughout the years, different researchers have attempted to demonstrate the safety and efficacy of an oral switch of the antibiotic regimen, with only scarce success.

Background: In low-and-middle income countries, national representative household surveys such as the Demographic and Health Surveys (DHS) and the Malaria Indicator Surveys (MIS) are routinely carried out to assess the malaria risk and the coverage of related interventions. A two-stage sampling design was used to identify clusters and households within each cluster. To ensure confidentiality, DHS made the data available after jittering (displacement) of the geographical coordinates of the clusters, shifting their original locations within a radius of 10 km.

Dietary supplements have improved performance and muscle hypertrophy in athletes and nonathletes in the past few decades. Theracurmin, a nutraceutical supplement based on curcumin, has been highlighted by its anti-inflammatory and antioxidant properties in physiological and pathological conditions. This study aimed to investigate the effects of theracurmin intake (300 mg/kg), containing 30 mg/kg of curcumin, in male Swiss mice (n = 66) under distinct protocols of climbing stairs (strength exercise) and their respective detraining period.

Knowing when and where infected mosquitoes bite is required for estimating accurate measures of malaria risk, assessing outdoor exposure, and designing intervention strategies. This study combines secondary analyses of a human behaviour survey and an entomological survey carried out in the same area to estimate human exposure to malaria-infected Anopheles mosquitoes throughout the night in rural villages in south-eastern Tanzania. Mosquitoes were collected hourly from 6PM to 6AM indoors and outdoors by human landing catches in 2019, and tested for Plasmodium falciparum sporozoite infections using ELISA.

Background: The Anopheles funestus group includes at least 11 sibling species, with Anopheles funestus Giles being the most studied and significant malaria vector. Other species, like Anopheles parensis, are understudied despite their potential role in transmission. This article provides insights into the biology and insecticide susceptibility of An.

Background: Despite South Africa's well-established Civil Registration and Vital Statistics system (CRVS) and good completeness of death registration, challenges persist in terms of the quality of cause of death information and the delayed availability of mortality statistics. The introduction of an electronic medical certification of cause of death (eMCCD) system may offer opportunities to improve both the quality and timeliness of this information.

Methods: This study used an exploratory mixed methods design to investigate perceptions surrounding an electronic solution for registering deaths in South Africa.

Background: Most research on HIV-1 viremia and cancer risk is from high-income countries. We evaluated the association between HIV-1 viremia and the risk of various cancer types among people with HIV (PWH) in South Africa.

Methods: We analysed data from the South African HIV Cancer Match study, based on laboratory measurements from the National Health Laboratory Services and cancer records from the National Cancer Registry from 2004-2014.

For over three decades, praziquantel (PZQ) has been the mainstay chemotherapy for prevention and treatment of schistosomiasis. The excessive use of PZQ, coupled with the lack of advanced drug candidates in the current anti-schistosomiasis drug development pipeline, emphasizes the genuine need for new drugs. In the current work, we investigated the antischistosomal potential of a new series of compounds derived from the privileged benzimidazole scaffold, which exhibited low micromolar IC potency in the range of 1.

Plant-plant interactions are major determinants of the dynamics of terrestrial ecosystems. There is a long tradition in the study of these interactions, their mechanisms and their consequences using experimental, observational and theoretical approaches. Empirical studies overwhelmingly focus at the level of species pairs or small sets of species.

Digital clinical decision support tools have contributed to improved quality of care at primary care level health facilities. However, data from real-world randomized trials are lacking. We conducted a cluster randomized, open-label trial in Tanzania evaluating the use of a digital clinical decision support algorithm (CDSA), enhanced by point-of-care tests, training and mentorship, compared with usual care, among sick children 2 to 59 months old presenting to primary care facilities for an acute illness in Tanzania (ClinicalTrials.
