Monitoring, Evaluation, and Learning Platform USAID, Jakarta, Indonesia.
Background: Indonesia's vast archipelago and substantial population size present unique challenges in addressing its multifaceted HIV epidemic, with 90% of its 514 districts and cities reporting cases. Identifying key populations (KPs) is essential for effectively targeting interventions and allocating resources to address the changing dynamics of the epidemic.
Objective: We examine the 2022 mapping of Indonesia's KPs to develop improved HIV and AIDS interventions.

Antimicrobial resistance (AMR) is a major threat to global public health that continues to grow owing to selective pressure caused by the use and overuse of antimicrobial drugs. Resistance spread by plasmids is of special concern, as they can mediate a wide distribution of AMR genes, including those encoding extended-spectrum -lactamases (ESBLs). The CTX-M family of ESBLs has rapidly spread worldwide, playing a large role in the declining effectiveness of third-generation cephalosporins.

Conventional small-molecule drugs primarily operate by inhibiting protein function, but this approach is limited when proteins lack well-defined ligand-binding pockets. Targeted protein degradation (TPD) offers an alternative approach by harnessing cellular degradation pathways to eliminate specific proteins. Recent studies have expanded the potential of TPD by identifying additional E3 ligases, with DCAF16 emerging as a promising candidate for facilitating protein degradation through both proteolysis-targeting chimera (PROTAC) and molecular glue mechanisms.

Quantum crystallography methods have been employed to investigate complex formation between nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase (COX) enzymes, with particular focus on the COX-1 and COX-2 isoforms. This study analyzed the electrostatic interaction energies of selected NSAIDs (flurbiprofen, ibuprofen, meloxicam and celecoxib) with the active sites of COX-1 and COX-2, revealing significant differences in binding profiles. Flurbiprofen exhibited the strongest interactions with both COX-1 and COX-2, indicating its potent binding affinity.

SARS-CoV-2 variant recurrence has emphasized the imperative prerequisite for effective antivirals. The main protease (Mpro) of SARS-CoV-2 is crucial for viral replication, making it one of the prime and promising antiviral targets. Mpro features several druggable sites, including active sites and allosteric sites near the dimerization interface, that regulate its catalytic activity.
