Breaking down global barriers: A multinational and multi-community approach to combat stigma and enhance mental wellbeing in people with HIV.

Introduction: The Joint United Nations Programme on HIV/AIDS (UNAIDS) Global 2025 targets prioritize action to overcome the collective barriers affecting the people and communities sitting on the outer margins of HIV care. Addressing the social and structural disparities that drive greater HIV prevalence and burden requires well-resourced, community-led responses that are fully integrated into national and global HIV initiatives.

Methods: The HIV Community Council (HCC), composed of 10 leaders from diverse global communities, convened to share their insights, amplify the community's voice, and identify barriers and solutions to empower all to live well with HIV through a dynamic, stepwise process of preparative work, deep discussion, prioritization, and consensus.

Dose by design: How limits on nicotine flux and puff duration affect the abuse liability of electronic nicotine delivery systems.

Introduction: Electronic nicotine delivery system (ENDS) product standards for nicotine flux (nicotine emitted/second), combined with limiting puff duration, could control nicotine dose and support ENDS regulations. We assessed behavioral and subjective abuse liability indices for ENDS varying in nicotine flux with fixed puff duration among people who smoke.

Methods: This within-subjects study included 32 adults who smoked cigarettes.

Smoking Discrimination Moderates the Relationship between Smoking Stigma and Cigarettes Per Day among Sexual and Gender Minority Individuals.

Sexual and gender minority (SGM) individuals report rates of tobacco use that range from 19% to 40% compared to roughly 20% of the general population. Higher rates of tobacco use, compounded by stress from discrimination, contribute to lower cessation rates and worse smoking-related outcomes for SGM individuals. Having multiple stigmatized identities, such as identifying as SGM and being a person who uses cigarettes, may further increase smoking, and decrease the likelihood of cessation.

The gene function encoding translation elongation factor eEF3 is partially conserved across fungi.

Introduction: Translation is a fundamental process of life. In eukaryotes, the elongation step of translation is highly conserved and is driven by eukaryotic translation elongation factors (eEF)1A and eEF2. A significant variation of the elongation is the activity of eukaryotic elongation factor (eEF) 3 in encoded by the gene yeast elongation factor () with orthologs in all fungal species, a few algae, and some protists.

Predictors of attrition in a randomized controlled trial of an electronic nicotine delivery system among people interested in cigarette smoking reduction.

Background: Mitigating attrition is a key component to reduce selection bias in longitudinal randomized controlled trials (RCTs). Few studies of electronic nicotine delivery systems (ENDS) allow for the examination of long-term retention. This analysis explores the relationship between attrition, baseline measures, and condition assigned for a RCT involving ENDS differing in nicotine delivery over a 24-week intervention period.

Translational control of papillomavirus mRNAs in the spotlight.

High-risk human papillomaviruses (HPVs) cause most cases of cervical cancer, a disease with an increasing impact worldwide. Recent studies have shown that the synthesis of viral oncoproteins is strongly subject to translational control. Thus, targeting the protein synthesis machinery might open novel avenues to develop innovative therapies aiming to improve patients' survival.

Climacteric and fibromyalgia: a review.

Fibromyalgia (FM) and climacteric conditions share common epidemiological and clinical features, with FM symptoms often beginning during menopause. Musculoskeletal pain, arthralgia, myalgia and other symptoms are frequently seen in both conditions. Some research suggests a link between the cessation of sex hormones and FM symptoms.

Challenges in the discovery of tumor-specific alternative splicing-derived cell-surface antigens in glioma.

Despite advancements in cancer immunotherapy, solid tumors remain formidable challenges. In glioma, profound inter- and intra-tumoral heterogeneity of antigen landscape hampers therapeutic development. Therefore, it is critical to consider alternative sources to expand the repertoire of targetable (neo-)antigens and improve therapeutic outcomes.

Characteristics and Risk Factors of Central Nervous System Infection in Children With Febrile Seizures.

Objective: The aim of the present study is to evaluate the necessity of performing lumbar puncture in patients experiencing febrile seizures, considering the epidemiology specific to Brazil.

Methods: A retrospective cross-sectional study was performed from January 2017 to December 2021.

Results: A total of 469 children with seizure and fever were analyzed.

Initial evidence of the acute effect of electronic nicotine delivery system use on energy intake.

Previous work has aimed to disentangle the acute effects of nicotine and smoking on appetite with mixed findings. Electronic nicotine delivery systems (ENDS) have yet to be examined in this regard despite evidence of use for weight control. The present study tested the influence of an ENDS on acute energy intake and associated subjective effects.

Rare Loxoscelism-Associated IgG Coombs-Positive Hemolytic Anemia Treated Successfully With Systemic Corticosteroids.

Loxoscelism-associated hemolytic anemia is a rare but critical complication of brown recluse spider bites. It may lead to various systemic manifestations, including jaundice, dark urine, and anemia-related symptoms, in addition to general loxoscelism symptoms such as skin lesions, fever, myalgia, nausea, and vomiting. Prompt diagnosis is crucial and requires recognizing typical laboratory findings such as low hemoglobin, elevated lactate dehydrogenase, reduced haptoglobin levels, and possibly a positive direct antiglobulin test.

Palm density and grazing effects on plant communities: implications for livestock management in a Butia palm grove.

Some grasslands in ecotones with forests tend to be encroached by woody species, because of changes in climate and land use. Such structural changes in vegetation can be facilitated when the grassland community presents an autochthonous arboreal component, like Butia palms. We aim to identify the responses of taxonomic and functional diversity on grassland community with the occurrence of arborescent/arboreal species (autochthonous and encroaching) to palm density and grazing intensity.

First Ecuadorian statement consensus for the evaluation and treatment of osteoporosis.

Unlabelled: Osteoporosis management has become more relevant as the life expectancy increases. In Ecuador, approximately 19% of adults over 65 years of age have been diagnosed with osteoporosis. There is no national consensus for the management and prevention of the disease being this proposal the first Ecuadorian consensus.

Eukaryotic translation initiation factor eIF4E-5 is required for spermiogenesis in Drosophila melanogaster.

Drosophila sperm development is characterized by extensive post-transcriptional regulation whereby thousands of transcripts are preserved for translation during later stages. A key step in translation initiation is the binding of eukaryotic initiation factor 4E (eIF4E) to the 5' mRNA cap. In addition to canonical eIF4E-1, Drosophila has multiple eIF4E paralogs, including four (eIF4E-3, -4, -5, and -7) that are highly expressed in the testis.
