Introduction: Decentralized molecular testing for infectious disease diagnosis at the point-of-care (POC) is critical to address inequities in access to timely, informed health care. The COVID-19 pandemic accelerated the demand, development and adoption of POC tests for infectious diseases globally. This has provided opportunities to maximize the individual benefits and public health impact of POC testing, particularly in remote and resource-limited primary care settings.

The stage is set for a new era of precariousness in modern medicine, driven by the increasing failure of a key pharmaceutical pillar-antimicrobials. In the context of sexually transmitted infections (STIs), the rise of antimicrobial resistance is introducing urgent questions around what might constitute "best practice" in a rapidly evolving scene, including the value of asymptomatic screening (test and treat), and the consequent downstream collateral damage emerging from over-use of our diminishingly effective antimicrobial resources. Drawing on interviews with clinicians, experts, and industry representatives, we examine resistance as a site of emerging and co-constitutive moral, temporal, and economic dilemmas.

Article Synopsis
  • - The study aimed to investigate the effects of replacing soybean meal (SBM) with canola meal (CM) or corn-distillers' dried grains with solubles (cDDGS) in reduced-protein diets on infected broiler chicks, using a sample of 1,120 birds divided into various diet and infection groups.
  • - Results indicated that while the diet had little effect on uninfected birds, the RP-SBM diet led to higher weight gain in infected birds and significant immune responses, such as increased bile anti-IgA and splenocyte proliferation.
  • - The findings suggest that partial replacement of SBM with CM or cDDGS offers minimal benefits, with only the RP-SBM diet showing notable positive outcomes

In this article, we examine the current management of sexually transmitted infections (STIs), in the context of rising antimicrobial resistance (AMR), through the lens of 'treatment cultures'. Prevailing treatment cultures-including the prominence of syndromic care for STIs-foster certain possibilities and foreclose others, with important consequences for countering AMR. Drawing on qualitative interviews with STI professionals, experts and industry representatives, we unpack these stakeholders' accounts of STI treatment cultures, drawing out the importance of socio-historical (i.

Background: Simplified hepatitis C virus (HCV) testing integrated into existing HIV services has the potential to improve HCV diagnoses and treatment. We evaluated the cost-effectiveness of integrating different simplified HCV testing strategies into existing HIV pre-exposure prophylaxis (PrEP) and treatment services among men who have sex with men (MSM) in Taiwan.

Methods: Mathematical modeling was used to assess the cost-effectiveness of integrating simplified HCV tests (point-of-care antibody, reflex RNA, or immediate point-of-care RNA) with HCV treatment into existing HIV prevention and care for MSM from a healthcare perspective.

In April 2020, the Aboriginal and Torres Strait Islander COVID-19 Point-of-Care (POC) Testing Program was initiated to improve access to rapid molecular-based SARS-CoV-2 detection in First Nations communities. At capacity, the program reached 105 health services across Australia. An external review estimated the program contributed to averting between 23,000 and 122,000 COVID-19 infections within 40 days of the first infection in a remote community, equating to cost savings of between AU$337 million and AU$1.

Article Synopsis
  • A 35-day study tested the effects of dietary supplements, Arginine (Arg) and branched-chain amino acids (BCAA), on broilers with low-protein diets infected with Eimeria, involving different diet groups and phases of evaluation.
  • Results showed that infected birds weighed and ate less overall, but those on Arg had better weight gain and feed conversion rates during early infection phases compared to NC and BCAA diets.
  • Additionally, while amino acid digestibility was reduced in infected birds, supplemental Arg improved digestibility for a brief period and impacted gene expression linked to protein synthesis, indicating a more positive role of Arg despite Eimeria infection.

Introduction: Simplified hepatitis C virus (HCV) diagnostic strategies have the potential to improve HCV diagnoses and treatment. We aimed to investigate the impact of simplified HCV diagnostic strategies on HCV incidence and its effect on HCV diagnosis and treatment among men who have sex with men (MSM) regardless of HIV status and use of HIV pre-exposure prophylaxis (PrEP) in Taiwan.

Methods: A compartmental deterministic model was developed to describe the natural history of HCV disease progression, the HCV care cascade and the HIV status and PrEP using among MSM.

Expeller soybean (ESB) is a widely used protein source in broiler diets due to its high amino acid digestibility. However, improper heat processing of ESB can negatively affect nutrient digestion, absorption, and metabolism leading to decreased growth performance. The study aimed to investigate the impact of varying processing temperatures on growth performance, amino acid digestibility (AID), and intestinal integrity using 3 different commercial batches of ESB processed at distinct temperatures.

Introduction: Progress toward hepatitis C virus (HCV) elimination is impeded by low testing and treatment due to the current diagnostic pathway requiring multiple visits leading to loss to follow-up. Point-of-care testing technologies capable of detecting current HCV infection in one hour are a 'game-changer.' These tests enable diagnosis and treatment in a single visit, overcoming the barrier of multiple visits that frequently leads to loss to follow-up.

Bone serves as a multifunctional organ in avian species, giving structural integrity to the body, aiding locomotion and flight, regulating mineral homeostasis, and supplementing calcium for eggshell formation. Furthermore, immune cells originate and reside in the bone marrow, sharing a milieu with bone cells, indicating a potential interaction in functions. In avian species, the prevalence of gastrointestinal diseases can alter the growth and the immune response, which costs a great fortune to the poultry industry.

Background: Microelimination of the hepatitis C virus (HCV) among men who have sex with men (MSM) could be complicated by continuous external introductions and the emergence of phylogenetic clusters harbouring clinically significant resistance-associated substitutions (RAS). To investigate international clustering and the prevalence and transmission of RAS, we aimed to analyse whole-genome HCV sequences from MSM with a recently acquired infection who participated in a large, international HCV treatment trial.

Methods: For this whole-genome analysis, we obtained HCV sequences from 128 MSM who had acquired HCV within the past 12 months and were participating in the REACT trial.

Fusarium toxins are one of the most common contaminants in poultry diets. The co-occurrence of fumonisins (FUM) and deoxynivalenol (DON), even at a subclinical dose, negatively affects the growth performance, intestinal integrity and induce subclinical necrotic enteritis in broiler chickens. Loss of gut integrity can be expected to alter the intestinal microbiota's composition.
