Background Virologic failure (VF) is still a major concern in the use of cabotegravir (CAB) and rilpivirine (RPV) long-acting (LA) for many healthcare professionals (HCP). While many results from clinical trials have been published, there is suspicion that they might underestimate the risk under less-controlled real-life conditions. This study aimed to estimate the probability of VF (primary objective) as well as discontinuation for any reason (secondary objective) among people with HIV (PWH) on CAB and RPV LA every two months (Q2M) in real life using Bayesian methodology.

Methodology: Fifteen GDPs were strategically selected for in-depth interviews. The informants were encouraged to describe in their own words and in as much detail as possible, the three most recent patient cases of PAAP of a root canal filled tooth, in which they decided to refrain from further treatment.
Whole-genome duplication (WGD) occurs in all kingdoms and impacts speciation, domestication, and cancer outcome. However, doubled DNA management can be challenging for nascent polyploids. The study of within-species polyploidy (autopolyploidy) permits focus on this DNA management aspect, decoupling it from the confounding effects of hybridization (in allopolyploid hybrids).

Here we present some unresolved questions in circadian biology research as posed by the editorial staff and guest contributors to the Journal of Circadian Rhythms. This collection of ideas is not meant to be comprehensive but does reveal the breadth of our observations on emerging trends in chronobiology and circadian biology.

However, some individuals maintain good health despite socioeconomic disadvantage. The aim of this qualitative study was to explore salutogenic (health-promoting) factors among healthy caries-free young adults of low socioeconomic status.

The accuracy of replication is one of the most important mechanisms ensuring the stability of the genome. The fork protection complex prevents premature replisome stalling and/or premature disassembly upon stress. Here, we characterize the Timeless-Tipin complex, a component of the fork protection complex.

During the day, we typically sit behind glass windows illuminated by artificial light that is >400 times dimmer and has a very different spectrum than natural daylight. On the opposite end are the nights that are now lit up by several orders of magnitude.
View Article and Find Full Text PDFCryptochromes (CRYs) are a structurally conserved but functionally diverse family of proteins that can confer unique sensory properties to organisms. In the marine bristle worm Platynereis dumerilii, its light receptive cryptochrome L-CRY (PdLCry) allows the animal to discriminate between sunlight and moonlight, an important requirement for synchronizing its lunar cycle-dependent mass spawning. Using cryo-electron microscopy, we show that in the dark, PdLCry adopts a dimer arrangement observed neither in plant nor insect CRYs.

The data on the use of the non-nucleoside reverse transcriptase inhibitor doravirine (DOR) and the integrase inhibitor dolutegravir (DTG) as an alternative 2DR remain scarce.
Methods: People living with HIV with DOR + DTG as a 2DR are being followed in a prospective observational study.
Aim: Prior to certain medical therapies, dental assessment and treatment of oral foci of infection are recommended. The aim of the present study was to acquire a deeper understanding of the decision-making process regarding the pre-medical management of root-canal-filled teeth with asymptomatic apical periodontitis (AAP).
Methodology: Hospital-affiliated dentists in Sweden were contacted for a semi-structured, in-depth interview.
Delayed HIV diagnosis at advanced stages of disease remains common (33%-64%). This analysis of the multi-center FindHIV study including newly diagnosed HIV-infected adults in Germany, focused on the potential role of socio-demographic and psychological factors on late diagnosis (formerly "late presentation", AIDS diagnosis or CD4 cells <350/µL). These data were collected from patient profiles, physician-patient interviews and questionnaires.

For functional reliability and precision, the frequency of these molecular oscillations must be stable at different environmental temperatures, known as "temperature compensation." Despite being an intrinsic property of all circadian clocks, this phenomenon is not well understood at the molecular level.

The mass-spawning bristle worm Platynereis dumerilii uses an endogenous monthly oscillator set by full moon to phase reproduction to specific days. But how do organisms recognize specific moon phases? We uncover that the light receptor L-Cryptochrome (L-Cry) discriminates between different moonlight durations, as well as between sun- and moonlight.

Methods: This was a retrospective study of all confirmed MPXV infections observed in the participating centres since 19 May 2022.
Many species synchronize their physiology and behavior to specific hours. It is commonly assumed that sunlight acts as the main entrainment signal for ∼24-h clocks. However, the moon provides similarly regular time information.

Objective: The aim of the study was to estimate the frequency of inadequately low concentrations of parathyroid hormone in the presence of hypocalcemia in people living with HIV.
Methods: This was a retrospective study that was conducted among PLWH enrolled in the ongoing ArcHIV study between 2016 and 2017.
Switching from a three-drug regimen (3DR: boosted darunavir [bDRV] and two nucleoside reverse transcriptase inhibitors [NRTIs]) to a two-drug regimen (2DR: bDRV and dolutegravir [DTG]) demonstrated non-inferiority with regard to viral suppression in people living with HIV (PLWH) in the DUALIS study. This sub-analysis focuses on changes in metabolic and renal parameters when sparing the NRTI backbone. DUALIS was a randomized, open-label, multicenter (27) phase 3-trial.

Materials And Methods: Fifteen staff members were strategically selected for the interview. All had completed a theoretical educational intervention including a complementary endodontic treatment strategy and, for the dentists, comprising training in the nickel-titanium-rotary-technique.
Risk factors in the environment such as air pollution and traffic noise contribute to the development of chronic noncommunicable diseases. Epidemiological data suggest that air pollution and traffic noise are associated with a higher risk for cardiovascular, metabolic, and mental disease, including hypertension, heart failure, myocardial infarction, diabetes, arrhythmia, stroke, neurodegeneration, depression, and anxiety disorders, mainly by activation of stress hormone signaling, inflammation, and oxidative stress. We here provide an in-depth review on the impact of the environmental risk factors air pollution and traffic noise exposure (components of the external exposome) on cardiovascular health, with special emphasis on the role of environmentally triggered oxidative stress and dysregulation of the circadian clock.
