234 participants maintained viral suppression through 96 weeks (90% male, 29% Black, median age 36 years). Serum leptin increased over 96 weeks (mean change 22%) while adiponectin did not (mean change 1%), which did not differ by study arm. Greater trunk, limb, and abdominal subcutaneous and visceral fat were associated with higher HOMA-IR and hsCRP at 96 weeks, but serum leptin level was a stronger determinant of these endpoints using a mediation model approach. A similar mediating effect was not observed for adiponectin.

Higher circulating leptin is associated with greater HOMA-IR and hsCRP independent of fat depot size, suggesting greater adipocyte lipid content may contribute to impaired glucose tolerance and systemic inflammation among PWH starting ART.

Based on the WHO Age-friendly Cities and Communities (AFCC) framework, the government of Manitoba, Canada, launched a province-wide age-friendly initiative in 2008. CIL56 clinical trial The objective of this study was to explore the sustainability of the AFCC initiative more than a decade later. The study was guided by conceptualizations of sustainability as multi-dimensional and dynamic, composed of four aspects (continued capacity; institutionalization; continued benefits; and development/adaptation), and an ecologic perspective that highlights the importance of contextual influences, and their change over time, on AFCC activities.

The study involved a qualitative, multiple case study design. Semi-structured interviews were conducted in 2020 with a key informant from each of 52 AFCC. Interview data were analyzed deductively, guided by the sustainability framework and an ecologic perspective. Census data was used to describe the demographic characteristics of AFCC.

We identified six groups of AFCC initiatives that varied iives.Digital photography and videography provide rich data for the study of animal behavior and are consequently widely used techniques. For fixed, unmoving cameras, the image sensor and optics govern the field of view and spatial detail. For a given sensor resolution, the optics determine a tradeoff between high magnification in which high spatial detail from a restricted field of view is obtained versus low magnification in which lower spatial detail is obtained from a larger region. In addition to this geometric resolution versus field of view tradeoff, limited light availability establishes a physical limit when imaging movement. If the animal is moving, motion blur smears the subject on the sensor during exposure. Practically, motion blur is further compounded by sensor inefficiency and noise. While these fundamental tradeoffs with stationary cameras can be sidestepped by employing multiple cameras and providing additional illumination, this may not always be desirable. An alternative that overcomes these issues of stationary cameras is to direct a high magnification camera at an animal continually as it moves. Here we review systems in which automatic tracking is used to maintain an animal in the working volume of a moving optical path. Such methods provide an opportunity to escape the tradeoff between resolution and field of view and also to reduce motion blur while still enabling automated image acquisition. We argue that further development will be useful and outline potential innovations that may improve the technology and lead to more widespread use.

Development of HIV remission strategies requires precise information on time to HIV rebound after treatment interruption, but there is uncertainty regarding whether modern ART regimens and timing of ART initiation may impact this outcome.

ACTG A5345 enrolled individuals who initiated ART during chronic or early HIV infection and on suppressive ART for ≥2 years. Participants underwent carefully monitored antiretroviral interruption. ART was restarted upon two successive viral loads ≥1,000 copies/mL. We compared participants of A5345 with participants of 6 historic ACTG treatment interruption studies.

Thirty-three chronic-treated and 12 early-treated participants interrupted ART with evaluable time to viral rebound. Median time to viral rebound ≥1000 HIV RNA copies/mL was 22 days. Acute retroviral rebound syndrome was diagnosed in 9% of chronic-treated and none of early-treated individuals. All participants of the historic studies were on older protease inhibitor-based regimens while 97% of A5345 participants were on integrase inhibitor-based ART. There were no differences in the timing of viral rebound comparing A5345 versus historic studies. In a combined analysis, a higher percentage of early-treated participants remained off ART at post-treatment interruption week 12 (chronic vs early 2% vs 9%, P=0.0496). One chronic-treated and one early-treated A5345 participant remained off ART for >24 weeks. All participants re-suppressed after ART re-initiation.

Early ART initiation, using either older or newer ART regimens, was associated with a significant delay in the time to HIV rebound after ART interruption, lowering the barrier for HIV remission.

Visualization of the metabolic pathways that comprise the metabolic network is extremely useful for interpreting a wide variety of experiments. Detailed annotated metabolic pathway maps for C. elegans is mostly limited to pan-organismal maps, many with incomplete or inaccurate pathway and enzyme annotations. Here we present WormPaths, which is composed of two parts 1) the careful manual annotation of metabolic genes into pathways, categories and levels, and 2) 62 pathway maps that include metabolites, metabolite structures, genes, reactions, and pathway connections between maps. These maps are available on the WormFlux website. We show that WormPaths provides easy-to-navigate maps and that the different levels in WormPaths can be used for metabolic pathway enrichment analysis of transcriptomic data. In the future we envision further developing these maps to be more interactive, with an analogy of road maps that are available on mobile devices.
