The question of whether to initiate ART at higher CD4+ cell counts than currently recommended by World Health Organization (WHO) treatment guidelines received much attention at the XVII International AIDS Conference (AIDS 2008). If studies presented at the conference ultimately lead to a revision of WHO treatment guidance, the estimated number of people who will need ART globally will increase substantially. Task-shifting is emerging as an important strategy for dealing with the acute shortage of health care workers in many high-burden countries, and several studies presented at AIDS 2008 demonstrated the impressive health system efficiencies garnered by using nurses or other health care providers to deliver HIV care and treatment. Other key presentations and discussion at the conference focused on the optimal time to start TB treatment in HIV-infected patients, the growing risk of resistance in high-burden countries, including its impact on future treatment options, and several large cohort trials testing optimal drug regimens in resource-limited settings.Biomedical prevention research continues to confirm the long-term, protective benefits of circumcision. Several studies involving HIV serodiscordant heterosexual couples have produced data suggesting a strong protective effect of ART for HIV-negative partners. Disappointing results from recent vaccine and non-ARV based microbicides trials are nevertheless providing important data to this field, and the expanding number of pre-exposure prophylaxis (PrEP) trials and ARV-based microbicides appear to provide the best hope for a new, efficacious biomedical prevention intervention.

Impact of the XVII Pacific Games on the National Referral Hospital Emergency Department, Solomon Islands.
Emerg Med Australas
February 2025
Department of Critical Care, Faculty of Medicine, Dentistry and Health Sciences, University of Melbourne, Melbourne, Victoria, Australia.
Background: The XVII Pacific Games was held in Honiara, Solomon Islands in 2023 and was attended by competitors from 24 Pacific nations. The National Referral Hospital (NRH) is the sole tertiary hospital and largest emergency department (ED) in the Solomon Islands, located in the capital city, Honiara, and was the designated referral hospital for the Pacific Games.
Objective: This report documents the lessons learnt from supporting a large international sporting event within a resource-limited health setting, and may help other EDs prepare for similar planned mass gatherings.
Benchmarking predictive methods for small-angle X-ray scattering from atomic coordinates of proteins using maximum likelihood consensus data.

Department of Neuroscience, University of Copenhagen, Blegdamsvej 3, 2200 Copenhagen, Denmark.
Stimulated by informal conversations at the XVII International Small Angle Scattering (SAS) conference (Traverse City, 2017), an international team of experts undertook a round-robin exercise to produce a large dataset from proteins under standard solution conditions. These data were used to generate consensus SAS profiles for xylose isomerase, urate oxidase, xylanase, lysozyme and ribonuclease A. Here, we apply a new protocol using maximum likelihood with a larger number of the contributed datasets to generate improved consensus profiles.

Article Synopsis
- - Autoimmune blistering disorders (AIBDs) include various conditions such as pemphigus and pemphigoid, characterized by blisters and skin lesions that can have diverse appearances, making accurate diagnosis essential for treatment and prognosis.
- - Diagnosis typically combines clinical evaluation with the detection of specific autoantibodies, utilizing tests like enzyme-linked immunosorbent assay (ELISA) and direct immunofluorescence microscopy (IFM), which is considered the gold standard.
- - Recent advancements in molecular identification of target antigens have led to new diagnostic methods and treatment approaches, enhancing the ability to detect specific antibodies related to various AIBDs.
Epidemiological surveillance and infectious disease outbreaks during mass international summertime sports gatherings: A narrative review.

The XXXIII Paris Summer Olympics followed by the XVII Paralympics Games will take place in France, predominantly in and around Paris, from July 26 to September 8, 2024. Public health stakeholders and decision-makers are called upon to set up or strengthen surveillance systems in areas hosting Olympic or Paralympic Games (OPGs) or large-scale international competitions, the objective being to detect and manage outbreaks should they occur during that period. We undertook a narrative review of the literature so as to identify major reported infectious disease outbreaks linked with or during OPGs / international sporting events during warm seasons.
