Effectiveness of PrEPTECH: Findings From a 180-Day Randomized Controlled Trial of a Pre-Exposure Prophylaxis Telehealth Intervention.

Background: Telehealth approaches are increasingly being used to provide access to pre-exposure prophylaxis (PrEP), an effective but underused HIV prevention modality. This randomized controlled trial of PrEPTECH, a telehealth intervention for the provision of HIV PrEP, seeks to assess its effects on PrEP access.

Methods: Young men who have sex with men and transgender women in Florida and California with an indication for PrEP were randomly assigned in a 1:1 allocation to receive access to PrEPTECH or a control condition, access to an online listing of PrEP resources in their communities.

Effect of a 12-Week Polyphenol Rutin Intervention on Markers of Pancreatic β-Cell Function and Gut Microbiota in Adults with Overweight without Diabetes.

Supplementation with prebiotic polyphenol rutin is a potential dietary therapy for type 2 diabetes prevention in adults with obesity, based on previous glycaemic improvement in transgenic mouse models. Gut microbiota are hypothesised to underpin these effects. We investigated the effect of rutin supplementation on pancreatic β-cell function measured as C-peptide/glucose ratio, and 16S rRNA gene-based gut microbiota profiles, in a cohort of individuals with overweight plus normoglycaemia or prediabetes.

Chilblains in immune-mediated inflammatory diseases: a review.

Chilblains were first described over a hundred years ago as cutaneous inflammatory lesions, typically on the digits, occurring on cold exposure. Chilblains can be primary, or secondary to a number of conditions such as infections, including COVID-19, and immune-mediated inflammatory disorders (IMIDs) with SLE being the commonest. Chilblain lupus erythematosus (CHLE) was first described in 1888 as cold-induced erythematous lesions before the terms 'chilblains' or 'perniosis' were coined.

Viral manipulation of functionally distinct interneurons in mice, non-human primates and humans.

Recent success in identifying gene-regulatory elements in the context of recombinant adeno-associated virus vectors has enabled cell-type-restricted gene expression. However, within the cerebral cortex these tools are largely limited to broad classes of neurons. To overcome this limitation, we developed a strategy that led to the identification of multiple new enhancers to target functionally distinct neuronal subtypes.

Women's empowerment: Finding strength in self-compassion.

Empowerment is often a desired outcome for health programs; however, it is rarely evaluated. One way to increase empowerment may be through self-compassion. The authors of the current study aimed to determine whether self-compassion and empowerment were positively related.

Who Owns the Data? Open Data for Healthcare.

Research on large shared medical datasets and data-driven research are gaining fast momentum and provide major opportunities for improving health systems as well as individual care. Such open data can shed light on the causes of disease and effects of treatment, including adverse reactions side-effects of treatments, while also facilitating analyses tailored to an individual's characteristics, known as personalized or "stratified medicine." Developments, such as crowdsourcing, participatory surveillance, and individuals pledging to become "data donors" and the "quantified self" movement (where citizens share data through mobile device-connected technologies), have great potential to contribute to our knowledge of disease, improving diagnostics, and delivery of -healthcare and treatment.

'No news today': talk of witnessing with families of missing people.

The paper contributes new ways of thinking about and responding to interview talk in the context of recent scholarship on interviewing, orality and witnessing. We proceed by paying attention to specific examples of interview talk on the experience of absence via the collecting of narratives from families of missing people. We highlight how ambiguous emotions are bound up with broader ways of recognizing such talk, largely exercised here as reflections on what is involved in witnessing those who are missing in communications with police.

Sophie's story: writing missing journeys.

'Sophie's story' is a creative rendition of an interview narrative gathered in a research project on missing people. The paper explains why Sophie's story was written and details the wider intention to provide new narrative resources for police officer training, families of missing people and returned missing people. We contextualize this cultural intervention with an argument about the transformative potential of writing trauma stories.

In vitro antimicrobial activity of silver-processed catheters for neurosurgery.

Objectives: To investigate the in vitro antibacterial activity of silver-processed catheters for use in neurosurgery using clinically predictive tests.

Methods: The antimicrobial activity of a commercially available silver-processed external ventricular drain catheter was evaluated against Staphylococcus epidermidis, methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli and Propionibacterium acnes. Non-impregnated catheters were used as controls.

Disseminated clustered juvenile xanthogranuloma: an unusual morphological variant of a common condition.

Juvenile xanthogranuloma (JXG) is a benign, self-healing non-Langerhans cell histiocytosis of unknown aetiology, most commonly occurring in infants and children. JXG is characterized by solitary or multiple yellowish cutaneous nodules, the two common clinical variants being a small nodular form and large nodular form, which frequently coexist. Unusual morphological presentations include keratotic, lichenoid, pedunculated, subcutaneous, clustered, plaque-like and giant lesions.

Single-molecule measurement of the stiffness of the rigor myosin head.

The force-extension curve of single myosin subfragment-1 molecules, interacting in the rigor state with an actin filament, has been investigated at low [ATP] by applying a slow triangle-wave movement to the optical traps holding a bead-actin-bead dumbbell. In combination with a measurement of the overall stiffness of the dumbbell, this allowed characterization of the three extensible elements, the actin-bead links and the myosin. Simultaneously, another method, based on an analysis of bead position covariance, gave satisfactory agreement.

Allogeneic bone marrow transplantation in a 7-year-old girl with congenital erythropoietic porphyria: a treatment dilemma.

Congenital erythropoietic porphyria (CEP, Günther's disease) has a very variable phenotype. In the more severely affected, bone marrow transplantation (BMT) is potentially curative, but is not without risks. We describe a 7-year-old girl with CEP characterized by severe photosensitivity but only mild anaemia, in whom the difficult decision to proceed with allogeneic BMT was made after discussion in a multidisciplinary team.

Lentigo maligna : prognosis and treatment options.

Lentigo maligna is a premalignant melanocytic neoplasm occurring on the sun-exposed skin of the middle-aged and elderly. It is believed to represent the in situ phase of lentigo maligna melanoma and, as such, cure is usually the aim of treatment. However, factors such as site and size of lesion and patient co-morbidities may influence the treatment modality undertaken.

Fumaric acid esters in severe psoriasis, including experience of use in combination with other systemic modalities.

Background: Fumaric acid esters (FAE) are used as a systemic treatment for severe psoriasis in Germany but there has been only very little published experience from the U.K. The potential for use in combination with other systemic drugs has not been explored.
