Therapeutic drug monitoring of tenofovir disoproxil and emtricitabine in oral HIV pre-exposure prophylaxis (PrEP) users who have undergone gastrointestinal surgery.

Objectives: Oral HIV pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV, but its efficacy depends on adequate absorption of drug, which may decrease following gastrointestinal surgery.

Methods: Clinicians across eight Genito-urinary Medicine clinics in the United Kingdom submitted data on PrEP users with history of gastrointestinal surgery who were referred to a national complex PrEP multi-disciplinary team between June 2021 and April 2023. Anonymised data were submitted on demographics, surgical history, PrEP regimen, and results of therapeutic drug monitoring (TDM) and HIV screening tests.

BASHH UK guidelines for the management of syphilis 2024.

The 2024 UK guidelines for the management of syphilis are in line with current evidence and practice within the UK. Key updates are detailed at the start of the article. These guidelines are accompanied by the first UK guidelines for the management of syphilis in pregnant people and children, 2024.

A revision of the new genus Nakahara, Willmott & Espeland, gen. n., described for Fabricius, 1776 (Lepidoptera, Nymphalidae, Satyrinae).

We here propose a new, monotypic genus, Nakahara, Willmott & Espeland, , to harbor a common Neotropical butterfly, described as Fabricius, 1776, and hitherto placed in the genus Forster, 1964. Recent and ongoing molecular phylogenetic research has shown to be polyphyletic, with proving to be unrelated to remaining species and not readily placed in any other described genus. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil.

Timing and location of reproduction in African waterfowl: an overview of >100 years of nest records.

The timing and location of reproduction are fundamental elements of reproductive success for all organisms. Understanding why animals choose to reproduce at particular times and in particular places is also important for our understanding of other aspects of organismal ecology, such as their habitat requirements, movement strategies, and biogeography. Although breeding patterns in waterfowl are relatively well documented, most studies are from northern temperate regions and the influences of location and time of year on breeding in Afrotropical ducks (Anatidae) are poorly understood.

Validity, reliability, and sensitivity-to-change properties of the psoriatic arthritis screening and evaluation questionnaire.

Psoriatic arthritis (PsA) is an inflammatory arthritis associated with irreversible joint damage in a subset of individuals. There is a need to screen early for this condition to prevent damage. To meet this need, we have developed the psoriatic arthritis screening and evaluation (PASE) questionnaire.

Long-term effects of 2 energy-restricted diets differing in glycemic load on dietary adherence, body composition, and metabolism in CALERIE: a 1-y randomized controlled trial.

Background: There remains no consensus about the optimal dietary composition for sustained weight loss.

Objective: The objective was to examine the effects of 2 dietary macronutrient patterns with different glycemic loads on adherence to a prescribed regimen of calorie restriction (CR), weight and fat loss, and related variables.

Design: A randomized controlled trial (RCT) of diets with a high glycemic load (HG) or a low glycemic load (LG) at 30% CR was conducted in 34 healthy overweight adults with a mean (+/-SD) age of 35 +/- 6 y and body mass index (kg/m(2)) of 27.

The ecology of dippers Cinclus cinclus (L.) in relation to stream acidity in upland Wales: time-activity budgets and energy expenditure.

The time-activity budget and energy expenditure of a riverine bird, the dipper Cinclus cinclus, was studied from March 1988 to July 1989, across a range of streams of contrasting acidity in upland Wales. Differences in time-activity budgets of birds on acidic and circumneutral streams were consistent with documented differences in prey availability and diet. Birds spent a significantly greater proportion of their active day foraging, swimming and flying, and less time resting, on acidic streams.
