Public hospital-based care for abortive events in Mexico: complication rates and socio-demographic factors, 2018-2022.

Background: Abortion-related complications are difficult to measure due to lack of standardized definitions and limited available data. We describe the proportion of abortive events that result in a documented complication in Mexico's public sector hospitals.

Methods: We used ICD-10 codes from Mexico's hospital discharge system (2018-2022), Subsistema Automatizado de Egresos Hospitalarios (SAEH), to describe abortive events admitted to hospitals: complications for excessive bleeding, infection, embolism, and unspecified; patient socio-demographic and clinical characteristics; and municipality-level structural vulnerability.

Unraveling the genetic architecture of blueberry fruit quality traits: major loci control organic acid content while more complex genetic mechanisms control texture and sugar content.

Background: Fruit quality traits, including taste, flavor, texture, and shelf-life, have emerged as important breeding priorities in blueberry (Vaccinium corymbosum). Organic acids and sugars play crucial roles in the perception of blueberry taste/flavor, where low and high consumer liking are correlated with high organic acids and high sugars, respectively. Blueberry texture and appearance are also critical for shelf-life quality and consumers' willingness-to-pay.

Changes in muscle performance among older adults with myeloid malignancies engaging in a mobile health (mHealth) exercise intervention: a single arm pilot study.

Background: Older adults with cancer are vulnerable to declines in muscle performance (e.g., strength, speed, duration of muscular contraction), which are associated with worse cancer-related outcomes.

Simulated retail food environments: A literature review of systems science approaches to advance equity in access to healthy diets.

As researchers increasingly utilize systems science simulation modeling (SSSM), little is known about how and by whom SSSMs are being leveraged to address inequities in access to healthy diets. We evaluated the extent to which studies (n = 66) employing SSSM to examine retail food environments (RFEs): included three pillars of equity (social position, human capital, socioeconomic and political context) that shape RFEs and access to healthy diets; grounded model design and development in theory; engaged with diverse stakeholders and lived experiences related to RFEs; and translated model findings towards addressing inequities in RFEs. Most studies (n = 58) included some model characteristics related to social position (e.

Identification of a Subpopulation of Astrocyte Progenitor Cells in the Neonatal Subventricular Zone: Evidence that Migration is Regulated by Glutamate Signaling.

In mice engineered to express enhanced green fluorescent protein (eGFP) under the control of the entire glutamate transporter 1 (GLT1) gene, eGFP is found in all 'adult' cortical astrocytes. However, when 8.3 kilobases of the human GLT1/EAAT2 promoter is used to control expression of tdTomato (tdT), tdT is only found in a subpopulation of these eGFP-expressing astrocytes.

Continued Treatment with Nintedanib in Patients with Progressive Pulmonary Fibrosis: Data from INBUILD-ON.

Purpose: In the INBUILD trial in patients with progressive pulmonary fibrosis (PPF), nintedanib slowed the decline in forced vital capacity (FVC) versus placebo, with a safety profile characterised mainly by gastrointestinal events. INBUILD-ON, the open-label extension of INBUILD, assessed the safety of nintedanib during longer-term treatment. Data on FVC were collected.

Differences in anxiety, depression and pain experience among adults with chronic low back pain as a function of nicotine product use.

The landscape of nicotine use in the United States (US) has continued to evolve, with electronic cigarette use (hereafter e-cigarette) becoming more evident in recent years. Patterns of dual nicotine use, or using combustible nicotine in conjunction with e-cigarettes, may increase dependence on nicotine, continued exposure to toxins, and corresponding health risks. One of the most prevalent health problems related to nicotine use is the experience of chronic pain.

Minority stress in relation to biological outcomes among sexual and gender minority people: a systematic review and update.

Here we present an updated systematic review identifying studies published 2019-2024, since our prior systematic review in 2020, that examine the association between minority stress and a biological outcome among sexual and gender minority (SGM) people. Pubmed, Web of Science, and Embase were queried to identify studies that examined an association between minority stress (including prejudice events and conditions, anticipation of rejection and discrimination, concealment or disclosure of SGM identity(ies), internalized stigma, or structural stigma) and a biological health outcome among SGM people. Included studies were coded for methodological approaches, study population, minority stress measure, biological outcomes, count of overall analyses, and count of analyses where an association was detected.

A Bibliometric Analysis on Multi-epitope Vaccine Development Against SARS-CoV-2: Current Status, Development, and Future Directions.

The etiological agent for the coronavirus disease 2019 (COVID-19), the SARS-CoV-2, caused a global pandemic. Although mRNA, viral-vectored, DNA, and recombinant protein vaccine candidates were effective against the SARS-CoV-2 Wuhan strain, the emergence of SARS-CoV-2 variants of concern (VOCs) reduced the protective efficacies of these vaccines. This necessitates the need for effective and accelerated vaccine development against mutated VOCs.

The Influence of Project ECHO and Integrated Behavioral Health in Primary Care on Emergency Department Visits Among Youth Diagnosed with Depression.

Rates of depression among youth and emergency department (ED) visits for un- or under-treated symptoms are on the rise. Early identification and treatment of depression is imperative at the patient, program, system, and population levels. This paper examines the individual and cumulative impact of Project ECHO and the inclusion of IBH services in pediatric primary care practices on mental health-related ED rates among youth diagnosed with depression for those practices.

Aberrant neural event segmentation during a continuous social narrative in trauma-exposed older adolescents and young adults.

Post-traumatic stress and major depressive disorders are associated with "overgeneral" autobiographical memory, or impaired recall of specific life events. Interpersonal trauma exposure, a risk factor for both conditions, may influence how symptomatic trauma-exposed (TE) individuals segment everyday events. The ability to parse experience into units (event segmentation) supports memory.

Impact of COVID-19 Public Health Measures on Antiretroviral Therapy Use Among Ugandans Living with HIV in Sero-Different Couples.

Antiretroviral therapy (ART) use and HIV suppression among people living with HIV (PLHIV) are critical for HIV control and prevention. Extreme restrictions on movement early during the COVID-19 pandemic in Uganda may have impeded the ability to initiate and sustain access to and use of ART. From our stepped-wedge cluster-randomized trial of an integrated PrEP and ART intervention for HIV-serodifferent couples at 12 ART clinics in Uganda, we identified participants who enrolled and had a 6-month post-ART initiation viral load measured before the beginning of the first COVID-19 lockdown (Period 1), participants whose enrollment and 6-month viral load measurement straddled pre-COVID and COVID lockdown times (Period 2), and participants whose enrollment and 6-month viral load were quantified entirely during COVID-19 (Period 3).

Commutability assessment of new standard reference materials (SRMs) for determining serum total 25-hydroxyvitamin D using ligand binding and liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays.

Commutability is where the measurement response for a reference material (RM) is the same as for an individual patient sample with the same concentration of analyte measured using two or more measurement systems. Assessment of commutability is essential when the RM is used in a calibration hierarchy or to ensure that clinical measurements are comparable across different measurement procedures and at different times. The commutability of three new Standard Reference Materials (SRMs) for determining serum total 25-hydroxyvitamin D [25(OH)D], defined as the sum of 25-hydroxyvitamin D [25(OH)D] and 25-hydroxyvitamin D [25(OH)D], was assessed through an interlaboratory study.

IRE1α-XBP1 safeguards hematopoietic stem and progenitor cells by restricting pro-leukemogenic gene programs.

Hematopoietic stem cells must mitigate myriad stressors throughout their lifetime to ensure normal blood cell generation. Here, we uncover unfolded protein response stress sensor inositol-requiring enzyme-1α (IRE1α) signaling in hematopoietic stem and progenitor cells (HSPCs) as a safeguard against myeloid leukemogenesis. Activated in part by an NADPH oxidase-2 mechanism, IRE1α-induced X-box binding protein-1 (XBP1) mediated repression of pro-leukemogenic programs exemplified by the Wnt-β-catenin pathway.

Short-chain fatty acid metabolites propionate and butyrate are unique epigenetic regulatory elements linking diet, metabolism and gene expression.

The short-chain fatty acids (SCFAs) propionate and butyrate have beneficial health effects, are produced in large amounts by microbial metabolism and have been identified as unique acyl lysine histone marks. To better understand the function of these modifications, we used chromatin immunoprecipitation followed by sequencing to map the genome-wide location of four short-chain acyl histone marks, H3K18pr, H3K18bu, H4K12pr and H4K12bu, in treated and untreated colorectal cancer (CRC) and normal cells as well as in mouse intestines in vivo. We correlate these marks with open chromatin regions and gene expression to access the function of the target regions.

Non-Caucasian Race/Ethnicity Predisposes to Unfavorable Stage and Grade at Upper Tract Urothelial Carcinoma Diagnosis.

Objective: To test whether race/ethnicity affects stage or grade distribution at upper tract urothelial carcinoma (UTUC) diagnosis.

Methods: Within the Surveillance, Epidemiology, and End Results (SEER) database 2004-2020, UTUC patients were identified. Multivariable logistic regression models tested for the association between race/ethnicity and stage as well as grade at diagnosis according to renal pelvis vs.

Conditional Deletion of Gremlin-1 in Cathepsin K-expressing Mature Osteoclasts Altered the Skeletal Response to Calcium Depletion in Sex-Dependent Manner.

This study assessed the novel concept that osteoclast-derived Grem1 has regulatory functions in the skeletal response to calcium stress using an osteoclastic Grem1 conditional knockout (cKO) mouse model. The calcium stress was initiated by feeding cKO mutants and wildtype (WT) littermates a calcium-deficient diet for 2 weeks. Deletion of Grem1 in mature osteoclasts did not affect developmental bone growth nor basal bone turnover.

Pterional vs. mini-pterional craniotomy for intracranial aneurysms: a systematic review and meta-analysis.

The mini-pterional craniotomy (mPT) was designed to be a minimally invasive alternative to the standard pterional (PT) approach. However, it remains unclear which technique produces better results. Thus, we aimed to perform a meta-analysis comparing functional, surgical, and aesthetic outcomes between mPT and PT in intracranial aneurysms.

Impact of RSVpreF vaccination on reducing the burden of respiratory syncytial virus in infants and older adults.

Respiratory syncytial virus (RSV) causes a substantial health burden among infants and older adults. Prefusion F protein-based vaccines have shown high efficacy against RSV disease in clinical trials, offering promise for mitigating this burden through maternal and older adult immunization. Employing an individual-based model, we evaluated the impact of RSV vaccination on hospitalizations and deaths in 13 high-income countries, assuming that the vaccine does not prevent infection or transmission.

A Trauma-Focused Screening Approach for Teen Dating Violence Prevention.

Developing accurate and equitable screening protocols can lead to more targeted, efficient, and effective, teen dating violence (TDV) prevention programming. Current TDV screening protocols perform poorly and are rarely implemented, but recent research and policy emphasizes the importance of leveraging more trauma-focused screening measures for improved prevention outcomes. In response, the present study examined which adversities (i.

Virus Association with Bacteria and Bacterial Cell Components Enhance Virus Infectivity.

The transmission and infection of enteric viruses can be influenced by co-existing bacteria within the environment and host. However, the viral binding ligands on bacteria and the underlying interaction mechanisms remain unclear. This study characterized the association of norovirus surrogate Tulane virus (TuV) and murine norovirus (MNV) as well as the human enteric virus Aichi virus (AiV) with six bacteria strains (Pantoea agglomerans, Pantoea ananatis, Bacillus cereus, Enterobacter cloacae, Exiguobacterium sibiricum, Pseudomonas spp.

Genetic and epigenetic characterization of sarcoma stem cells across subtypes identifies EZH2 as a therapeutic target.

High-grade soft tissue sarcomas (STS) are a heterogeneous and aggressive set of cancers. Failure to respond anthracycline chemotherapy, standard first-line treatment, is associated with poor outcomes. We investigated the contribution of STS cancer stem cells (STS-CSCs) to doxorubicin resistance.

Characterizing phenotype variants of Cercosporidium personatum, causal agent of peanut late leaf spot disease, their morphology, genetics and metabolites.

Cercosporidium personatum (CP) causes peanut late leaf spot (LLS) disease with 70% yield losses unless controlled by fungicides. CP grows slowly in culture, exhibiting variable phenotypes. To explain those variations, we analyzed the morphology, genomes, transcriptomes and chemical composition of three morphotypes, herein called RED, TAN, and BROWN.

Age Matters: Early-Onset Rectal Cancer Exhibits Higher Rates of Pathological Complete Response: A Retrospective Analysis of the Influence of Young Age on Treatment Success in Stage II-III Rectal Cancer.

Background: The incidence of rectal cancer has decreased overall, but the incidence of early-onset rectal cancer (eoRC) has increased. Early-onset rectal cancer and late-onset rectal cancer (loRC) differ due to phenotypical, genetic characteristics, and higher stage presentations in eoRC. Thus, eoRC patients undergo more aggressive neoadjuvant treatments.

Surgical Margins and Oncologic Outcomes Following Wedge Resection of Pulmonary Metastases in Pediatric and Young Adult Patients with Sarcoma.

Introduction: Children and young adults diagnosed with sarcoma often present with pulmonary metastases requiring wedge resection. It is important to balance the risk of pulmonary recurrence against the desire to limit resection of benign parenchyma. This study aims to determine the impact of resection margins on survival and recurrence among pediatric and young adult sarcoma patients.
