The study aims to explain the discourse of the collective subject of adult and elderly men about the experience of long COVID. Qualitative research, derived from a national multicenter clinical-virtual observatory involving 92 adult men, between 2022 and 2023 in Brazil. IRaMuTeQ software was used (data processing), the Collective Subject Discourse technique (analysis) and socio-anthropological references of the disease experience (interpretation).

Introduction Explicit outcomes routinely measured across the life span following hypospadias surgery, defined by a core outcome set (COS), will harmonize and overcome reporting heterogeneity. Methods Age specific outcomes identified in a literature review were presented in a three round Delphi survey. Participants (professionals, parents and patients) were encouraged to suggest outcomes in the first Delphi round.

Objectives: Despite the increasing investments in Latin American healthcare, the corresponding improvement in population health is not proportional. This discrepancy may be attributed to the efficiency of resource utilization. This study used the data envelopment analysis (DEA) methodology to assess the efficiency of healthcare systems in 23 Latin American and Caribbean countries.

Periodontitis, an oral disease initiated by a dysbiotic dental biofilm, has an unclear response to photobiomodulation (PBM) as an adjunctive treatment. This study investigates the effects of PBM on reactive oxygen species (ROS), apoptosis, oxidative stress, and inflammatory markers in a periodontitis model using C57BL/6 mice, divided into four groups: control (C), control + PBM (C + PBM), periodontitis (P), and periodontitis + PBM (P + PBM). An infrared diode laser (808 nm, 133.

Article Synopsis
  • The study identifies seven microRNAs (miRNAs) that inhibit the proliferation of vascular smooth muscle cells (vSMCs), important in preventing vascular remodeling issues.
  • Through high-throughput screening of 2,042 human miRNA mimics, the researchers pinpointed miR-323a-3p, miR-449b-5p, miR-491-3p, miR-892b, miR-1827, miR-4774-3p, and miR-5681b as effective in reducing vSMC proliferation.
  • The findings suggest these miRNAs could be developed into therapeutic agents, particularly for conditions like vein graft failure, showing minimal toxicity and altering key cell-cycle gene networks involved in

Randomized controlled trials (RCTs) are at the top of the pyramid of evidence as they offer the best answer on the efficacy of a new treatment. RCTs are true experiments in which participants are randomly allocated to receive a certain intervention (experimental group) or a different intervention (comparison group), or no treatment at all (control or placebo group). Randomization, along with other methodological features such as blinding and allocation concealment, safeguard against biases.

To investigate the elements of the social network associated with frailty syndrome in older Brazilian adults. Baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil, 2015-2016) were used. Frailty was defined by the Fried phenotype (unintentional weight loss, exhaustion, weakness, slowness, and low level of physical activity).

Unlabelled: Previous studies have shown that E6 interacts with the E6-associated protein (E6AP) ubiquitin-protein ligase and directs its ubiquitylation activity toward several specific cellular proteins, one of the most important of which is p53. Interestingly, E6AP not only aids in the E6-directed degradation of cellular substrates but also stabilizes the E6 protein by protecting it from proteasome-mediated degradation. However, there is no information available about the ubiquitin ligases that regulate the stability and activity of the human papillomavirus (HPV) E6 oncoprotein in the absence of E6AP.

Article Synopsis
  • - The study aimed to explore how family characteristics, like having a partner or children, affect loneliness in Brazilians aged 50 and older, considering both the presence and severity of loneliness.
  • - Data was collected from over 7,000 participants in a national aging study, using a specific loneliness scale to measure loneliness alongside family dynamics such as marital status and living arrangements.
  • - Findings showed that family relationships with partners significantly impacted loneliness levels, with those cohabiting reporting lower loneliness; results suggest that enhancing social support for older adults with smaller family units is important.

Article Synopsis
  • - The study investigates the link between chronic illnesses like inflammatory bowel disease (IBD) and the presence of depressive or anxious disorders, aiming to see how these affect patients’ quality of life.
  • - A group of 141 patients participated, with data collected on demographics, lifestyle, and mental health using specific questionnaires, revealing that a significant portion suffered from anxiety and depression.
  • - Findings suggest that both anxiety and depression significantly lower the quality of life for patients with IBD, regardless of the severity of their illness.

In our polarized societies, more companies are taking a stand on divisive sociopolitical issues. However, given the mixed findings from previous studies, it remains unclear whether Corporate Activism (CA) is more likely to hurt or help a company's performance and reputation, or shape the public's attitudes toward the sociopolitical issue involved. To better understand the impact of CA in polarized societies, it is valuable to study moderating factors, especially those linked to polarization.

Viruses are abundant and ubiquitous in soil, but their importance in modulating greenhouse gas (GHG) emissions in terrestrial ecosystems remains largely unknown. Here, various loads of viral communities are introduced into paddy soils with different fertilization histories via a reciprocal transplant approach to study the role of viruses in regulating greenhouse gas emissions and prokaryotic communities. The results showed that the addition of viruses has a strong impact on methane (CH) and nitrous oxide (NO) emissions and, to a minor extent, carbon dioxide (CO) emissions, along with dissolved carbon and nitrogen pools, depending on soil fertilization history.

Triple-negative breast cancer is a heterogeneous disease with high recurrence and mortality, linked to cancer stem cells (CSCs). Our study characterized distinct cell subpopulations and signaling pathways to explore chemoresistance. We observed cellular heterogeneity among and within the cells regarding phenotyping and drug response.

Background: Queiroz et al. showed that the application of cluster methodology for classifying gastric cancer is suitable and efficient within a Brazilian cohort, which is known for its population heterogeneity. The study highlighted the potential utilization of this method within public health services due to its low-cost, presenting a viable means to improve the diagnosis and prognosis of gastric cancer.

The global prevalence of autism spectrum disorder (ASD) is increasing. ASD manifests with persistent social communication and interaction challenges, limited interests, and repetitive behaviors. As the scientific literature on ASD in adults varies greatly, mapping the recent global research becomes valuable for enhancing comprehension of this subject.

Article Synopsis
  • Micronuclei (MN) are formed through various mechanisms, and their frequent presence in tumors suggests they might actively contribute to cancer progression rather than being just passive byproducts.
  • This study highlights how damages during cell division can lead to the accumulation of Emerin in MN, which lack Lamin A/C and feature the Lamin-B receptor and Sec61β.
  • Emerin mislocalization to MN is linked to a poor prognosis in prostate cancer patients and is associated with increased migratory and invasive behaviors of tumor cells, particularly in environments rich in collagen.

  • The study reviews the outcomes of open distal ureteroureterostomy (UU) surgery for children with duplicated collecting systems and no lower pole vesicoureteral reflux (VUR), conducted across multiple centers from 2009 to 2022.
  • A total of 127 patients were analyzed, predominantly females, with most undergoing surgery due to prenatal hydronephrosis and a mean age of 18 months at operation.
  • Post-operative results showed a low complication rate, with the mean operative time being 86 minutes and an average hospital stay of 1.1 days; only a small percentage experienced minor complications.
