Tenofovir and Doravirine Are Potential Reverse-Transcriptase Analogs in Combination with the New Reverse-Transcriptase Translocation Inhibitor (Islatravir) Among Treatment-Experienced Patients in Cameroon: Designing Future Treatment Strategies for Low- and Middle-Income Countries.

Islatravir (ISL) is a novel antiretroviral that inhibits HIV-1 reverse transcriptase translocation. The M184V mutation, known to reduce ISL's viral susceptibility in vitro, could arise from prolonged exposure to nucleoside reverse transcriptase inhibitors (NRTI) (3TC). This study evaluated the predictive efficacy of ISL and identified potentially active antiretrovirals in combination among treatment-experienced patients in Cameroon, where NRTIs (3TC) have been the backbone of ART for decades now.

Investigations of Long-Acting Formulations in Children, Adolescents, and Pregnant Women: A Systematic Review.

Long-acting and extended-release drug delivery strategies have greatly improved treatment for a variety of medical conditions. Special populations, specifically infants, children, young people, and pregnant and postpartum women, could greatly benefit from access to these strategies but are often excluded from clinical trials. We conducted a systematic review of all clinical studies involving the use of a long-acting intramuscular injection or implant in infants, children, young people, and pregnant and postpartum people.

Evolutionary Trajectories of Shoots vs. Roots: Plant Volatile Metabolomes Are Richer but Less Structurally Diverse Belowground in the Tropical Tree Genus .

The breadth and depth of plant leaf metabolomes have been implicated in key interactions with plant enemies aboveground. In particular, divergence in plant species chemical composition-amongst neighbors, relatives, or both-is often suggested as a means of escape from insect herbivore enemies. Plants also experience strong pressure from enemies such as belowground pathogens; however, little work has been carried out to examine the evolutionary trajectories of species' specialized chemistries in both roots and leaves.

HIV Drug Resistance Profile in Clients Experiencing Treatment Failure After the Transition to a Dolutegravir-Based First-Line Antiretroviral Treatment Regimen in Mozambique.

Real-world data on HIV drug resistance (HIVDR) after transitioning to tenofovir disoproxil fumarate/lamivudine/dolutegravir (TLD) are limited. We assessed HIVDR rates and patterns in clients with virological failure (VF) after switching from an NNRTI-based regimen to TLD. A cross-sectional study was conducted in Gaza, Mozambique (August 2021-February 2022), including adults on first-line ART for ≥12 months who transitioned to TLD and had unsuppressed viral load (VL) ≥ 1000 copies/mL six months post-transition.

This study aimed to (1) examine the latent structure of the Polish version of the ERQ, and (2) use it to explore different profiles of emotion regulation strategy use and their links with mental health outcomes. : Our sample was 1197 Polish-speaking adults from the general community in Poland.

A Critical Reappraisal of Haloperidol for Delirium Management in the Intensive Care Unit: Perspective from Psychiatry.

Delirium is a complex neuropsychiatric syndrome with multifactorial pathophysiology, encompassing a wide range of neuropsychiatric symptoms, and its management remains a significant challenge in critical care. Although often managed with antipsychotics, like haloperidol, current research has predominantly focused on dopamine dysregulation as the primary driver of delirium, overlooking its broader neuroanatomical and neurochemical underpinnings. This has led to a majority of research focusing on haloperidol as a treatment for intensive care unit (ICU) delirium.

Quantitative Structure-Activity Relationship (QSAR) Modeling of Chiral CCR2 Antagonists with a Multidimensional Space of Novel Chirality Descriptors.

The development of chirality descriptors for quantitative chirality structure-activity relationship (QCSAR) modeling has always attracted attention, owing to the importance of chiral molecules in pharmaceutical, agriculture, food, and fragrance industries, and environmental toxicology. The utility of a multidimensional space of novel relative chirality indices (RCIs) in the QCSAR modeling of twenty CCR2 antagonists is reported upon in this paper. The numerical characterization of chirality by the RCI approach gives a large pool of chirality descriptors with different degrees of mutual correlation (the correlation coefficient among the computed descriptors varied from 0.

Improved Survival and Symptom Relief Following Palliative Cerebrospinal Fluid Diversion for Leptomeningeal Disease from Brain Cancers: A Case Series and Systematic Review.

Background: Leptomeningeal disease (LMD) from cancer indicates advanced cancer and can lead to obstructive hydrocephalus, for which palliative cerebrospinal fluid (CSF) diversion may be indicated to alleviate symptoms. We investigated surgical outcomes for hydrocephalus for adult patients with LMD and conducted a systematic review on pediatric and adult cases.

Methods: We analyzed outcomes from a 10-year period of patients with neoplastic LMD, obstructive hydrocephalus, and documented date of death.

Pharmacokinetics-Based Design of Subcutaneous Controlled Release Systems for Biologics.

Protein therapeutics have emerged as an exceedingly promising treatment modality in recent times but are predominantly given as intravenous administration. Transitioning to subcutaneous (SC) administration of these therapies could significantly enhance patient convenience by enabling at-home administration, thereby potentially reducing the overall cost of treatment. Approaches that enable sustained delivery of subcutaneously administered biologics offer further advantages in terms of less frequent dosing and better patient compliance.

Salivary gland stem/progenitor cells: advancing from basic science to clinical applications.

Salivary gland stem/progenitor cells (SSPCs) hold significant potential for regenerative medicine, especially for patients suffering from salivary gland dysfunction due to various causes such as radiation therapy, Sjögren's syndrome, and aging. This review provides a comprehensive overview of SSPCs, including their characteristics, isolation, culture techniques, differentiation pathways, and their role in tissue regeneration. Additionally, we highlight recent advances in cell- and tissue-based therapies, such as SSPC transplantation and bioengineered organ replacements.

Purpose: To evaluate frequency and timing of post-discharge complications in patients with traumatic rib fractures undergoing operative or nonoperative management.

Methods: We retrospectively reviewed adult patients with rib fractures admitted to a Level 1 trauma center from 1/2020 to 12/2021. Outcomes included rib-related complications, pneumonia within 1 month, new diagnosis of opioid- or alcohol-use disorder, and all-cause mortality.

Immune infiltrate populations within distinct tumor immune microenvironments predictive of immune checkpoint treatment outcome.

Understanding the dynamic tumor immune microenvironment (TIME) is important in guiding immunotherapy. We have previously validated signatures predictive of checkpoint inhibitor efficacy which distinguish immunomodulatory, mesenchymal stem-like, and mesenchymal phenotypes. Here we use twenty tumor types (7162 samples) to identify potentially conserved immune biology within these TIME spaces, genes co-expressed across distinct cell types involved these immune processes, and the association of these signatures with ICI response.

Practice Advisory for Postoperative Pain Management of Cardiac Surgical Patients: A Report by Society of Cardiovascular Anesthesiologists.

Moderate to severe pain after cardiac surgery is relatively common, which increases the risk of postoperative cardiopulmonary complications and delays hospital discharge. Opioids have been useful agents for postoperative pain control after cardiac surgery, but are associated with serious adverse effects. As a result, multimodal analgesia has been adopted widely to decrease reliance on opioids for treating postoperative pain, reduce opioid-related adverse effects, and promote early recovery.

Participants were told three different mints were trialled to avoid bias.

Associations between weather extremes and faecal contamination along pathogen transmission pathways in rural Bangladeshi households: a prospective observational study.

Background: Weather extremes are predicted to influence pathogen exposure but their effects on specific faecal-oral transmission pathways are not well investigated. We evaluated associations between extreme rain and temperature during different antecedent periods (0-14 days) and Escherichia coli along eight faecal-oral pathways in rural Bangladeshi households.

Methods: We used data from the WASH Benefits Bangladesh cluster-randomised controlled trial (NCT01590095).

Paediatric strategy forum for medicinal product development in diffuse midline gliomas in children and adolescents ACCELERATE in collaboration with the European Medicines Agency with participation of the Food and Drug Administration.

Fewer than 10 % of children with diffuse midline glioma (DMG) survive 2 years from diagnosis. Radiation therapy remains the cornerstone of treatment and there are no medicinal products with regulatory approval. Although the biology of DMG is better characterized, this has not yet translated into effective treatments.

Life cycle comparison of industrial-scale lithium-ion battery recycling and mining supply chains.

Recycling lithium-ion batteries (LIBs) can supplement critical materials and improve the environmental sustainability of LIB supply chains. In this work, environmental impacts (greenhouse gas emissions, water consumption, energy consumption) of industrial-scale production of battery-grade cathode materials from end-of-life LIBs are compared to those of conventional mining supply chains. Converting mixed-stream LIBs into battery-grade materials reduces environmental impacts by at least 58%.
