Uptake of Risk-Reducing Surgeries in an International Real-World Cohort of Hispanic Women.

Purpose: Women with pathogenic variants (PVs) in breast cancer (BC) and ovarian cancer (OC) associated genes are candidates for cancer risk-reducing strategies. Limited information is available regarding risk-reducing surgeries (RRS) among Hispanics. The aim of this study was to describe the uptake of RRS in an international real-world experience of Hispanic women referred for genetic cancer risk assessment (GCRA) and to identify factors affecting uptake.

Discovery of a brain penetrant small molecule antagonist targeting LPA1 receptors to reduce neuroinflammation and promote remyelination in multiple sclerosis.

Multiple sclerosis (MS) is a chronic neurological disease characterized by inflammatory demyelination that disrupts neuronal transmission resulting in neurodegeneration progressive disability. While current treatments focus on immunosuppression to limit inflammation and further myelin loss, no approved therapies effectively promote remyelination to mitigate the progressive disability associated with chronic demyelination. Lysophosphatidic acid (LPA) is a pro-inflammatory lipid that is upregulated in MS patient plasma and cerebrospinal fluid (CSF).

Cellular and Molecular Mechanisms of Neuronal Degeneration in Early-Stage Diabetic Retinopathy.

Background: Studies on the early retinal changes in Diabetic Retinopathy (DR) have demonstrated that neurodegeneration precedes vascular abnormalities like microaneurysms or intraretinal hemorrhages. Therefore, there is a growing field of study to analyze the cellular and molecular pathways involved to allow for the development of novel therapeutics to prevent the onset or delay the progression of DR. Molecular Mechanisms: Oxidative stress and mitochondrial dysfunction contribute to neurodegeneration through pathways involving polyol, hexosamine, advanced glycation end products, and protein kinase C.

Evidence of Active-Forgetting Mechanisms? Blocking Arachidonic Acid Release May Slow Forgetting of Sensitization in .

Long-term sensitization in is accompanied by a persistent up-regulation of mRNA encoding the peptide neurotransmitter Phe-Met-Arg-Phe-amide (FMRFa), a neuromodulator that opposes the expression of sensitization through activation of the arachidonic acid second-messenger pathway. We completed a preregistered test of the hypothesis that FMRFa plays a critical role in the forgetting of sensitization. received long-term sensitization training and were then given whole-body injections of vehicle (= 27), FMRFa (= 26), or 4-bromophenacylbromide (4-BPB; = 31), a phospholipase inhibitor that prevents the release of arachidonic acid.

TGF-β Signaling Pathways in the Development of Diabetic Retinopathy.

Diabetic retinopathy (DR), a prevalent complication of diabetes mellitus affecting a significant portion of the global population, has long been viewed primarily as a microvascular disorder. However, emerging evidence suggests that it should be redefined as a neurovascular disease with multifaceted pathogenesis rooted in oxidative stress and advanced glycation end products. The transforming growth factor-β (TGF-β) signaling family has emerged as a major contributor to DR pathogenesis due to its pivotal role in retinal vascular homeostasis, endothelial cell barrier function, and pericyte differentiation.

LiaX is a surrogate marker for cell envelope stress and daptomycin non-susceptibility in .

Daptomycin (DAP) is often used as a first-line therapy to treat vancomycin-resistant infections, but emergence of DAP non-susceptibility threatens the effectiveness of this antibiotic. Moreover, current methods to determine DAP minimum inhibitory concentrations (MICs) have poor reproducibility and accuracy. In enterococci, DAP resistance is mediated by the LiaFSR cell membrane stress response system, and deletion of encoding the response regulator results in hypersusceptibility to DAP and antimicrobial peptides.

Gnathic Schwannomas: A Report of Two Cases and Systematic Review of the Literature.

Background: The intraosseous schwannoma (IS) is a benign peripheral nerve sheath tumor postulated to arise de novo or from nerve fibers in preexisting nutrient canals. ISs are uncommon and comprise less than 1% of neoplasms originating in bone. We herein present two cases of mandibular schwannomas-the first case was a 66-year-old female with a four-month history of pain and pressure associated with an anterior mandibular radiolucency, and the second case was an asymptomatic 12-year-old female with separate radiolucencies of her mandibular symphysis and right posterior mandible.

Breaking Down Machismo: Shifting Definitions and Embodiments of Latino Manhood in Middle-Aged Latino Men.

There is a notable gap in empirical research regarding how Latino men define and demonstrate machismo, masculinity, and manhood as well as the behavioral consequences associated with these concepts. In our study, we employed a phenomenological thematic approach to analyze 20 semi-structured individual interviews conducted with Latino men residing in South Florida. Our primary objectives were twofold: to examine (1) how do Latino men ages 35 to 60 years describe what it means to be a man and (2) what are the attributes that these men seek to show others that demonstrate their character, cultural values, and gender identity.

Social connectedness and surviving at the margins: Findings from interviews with low-income Latino men in the U.S. Northeast.

Objectives: Structural and interpersonal discrimination can lead to social exclusion and limited social integration, inhibiting the use of support networks to gain access to health-protective material and social resources. Social support theories suggest that connectedness may moderate the link between discrimination and health risk. This study examined how risk factors (i.

Mind the Gaps: The Need for Inclusion of Male-Identified Voices in Adolescent Sexual and Reproductive Health.

Adolescent sexual and reproductive health (ASRH) inequities are well documented for historically excluded youth (i.e., youth of color, LGBTQIA+ youth, youth with disabilities, recently im/migrated youth) living in the U.

Epidemic control in networks with cliques.

Social units, such as households and schools, can play an important role in controlling epidemic outbreaks. In this work, we study an epidemic model with a prompt quarantine measure on networks with cliques (a clique is a fully connected subgraph representing a social unit). According to this strategy, newly infected individuals are detected and quarantined (along with their close contacts) with probability f.

Effect of a native bacterial consortium on growth, yield, and grain quality of durum wheat ( L. subsp. ) under different nitrogen rates in the Yaqui Valley, Mexico.

A field experiment was carried out to quantify the effect of a native bacterial inoculant on the growth, yield, and quality of the wheat crop, under different nitrogen (N) fertilizer rates in two agricultural seasons. Wheat was sown under field conditions at the Experimental Technology Transfer Center (CETT-910), as a representative wheat crop area from the Yaqui Valley, Sonora México. The experiment was conducted using different doses of nitrogen (0, 130, and 250 kg N ha) and a bacterial consortium (BC) ( TSO9, subsp.

Naringin prevents diabetic nephropathy in rats through blockage of oxidative stress and attenuation of the mitochondrial dysfunction.

We have studied the effects of naringin (NAR), a flavonoid from citric fruits, on morphology, ultrastructure and function of the kidney in streptozotocin (STZ)-induced diabetic rats. Two groups of animals were used: (1) control rats and (2) STZ rats (60 mg STZ/kg b.w.

Mitochondrial HO metabolism as central event of heart complex I syndrome in early diabetes.

Hydrogen peroxide is the main metabolite effective in redox regulation and it is considered an insulinomimetic agent, with insulin signalling being essential for normal mitochondrial function in cardiomyocytes. Therefore, the aim of this work was to deeply analyse the heart mitochondrial HO metabolism, in the early stage of type 1 diabetes. Diabetes was induced by Streptozotocin (STZ, single dose, 60 mg × kg, ip.

Predicting the HER2 status in oesophageal cancer from tissue microarrays using convolutional neural networks.

Background: Fast and accurate diagnostics are key for personalised medicine. Particularly in cancer, precise diagnosis is a prerequisite for targeted therapies, which can prolong lives. In this work, we focus on the automatic identification of gastroesophageal adenocarcinoma (GEA) patients that qualify for a personalised therapy targeting epidermal growth factor receptor 2 (HER2).

Electrical signals in the ER are cell type and stimulus specific with extreme spatial compartmentalization in neurons.

The endoplasmic reticulum (ER) is a tortuous organelle that spans throughout a cell with a continuous membrane containing ion channels, pumps, and transporters. It is unclear if stimuli that gate ER ion channels trigger substantial membrane potential fluctuations and if those fluctuations spread beyond their site of origin. Here, we visualize ER membrane potential dynamics in HEK cells and cultured rat hippocampal neurons by targeting a genetically encoded voltage indicator specifically to the ER membrane.

Oral granulomatosis with polyangiitis a systematic review.

Objective: Granulomatosis with polyangiitis is an unusual multisystemic inflammatory disease, with vasculitis of small- and medium-sized vessels, with a predilection for upper lower airways and kidneys. The etiology remains unknown although it may originate from different stimuli, in genetically susceptible patients.

Materials And Methods: A detailed database search was performed.

Electronic Health Record-Integrated Clinical Decision Support for Clinicians Serving Populations Facing Health Care Disparities: Literature Review.

Objectives: To review current studies about designing and implementing clinician-facing clinical decision support (CDS) integrated or interoperable with an electronic health record (EHR) to improve health care for populations facing disparities.

Methods: We searched PubMed to identify studies published between January 1, 2011 and October 22, 2021 about clinician-facing CDS integrated or interoperable with an EHR. We screened abstracts and titles and extracted study data from articles using a protocol developed by team consensus.

Socioeconomic impact and burden of hypertension in the Philippines projected in 2050.

Hypertension has remained the number one cause of cardiovascular death in the Philippines for over three (3) decades. Despite this finding, the burden accounted for by hypertension is investigated to a lesser extent. We performed this study to determine the socioeconomic impact of hypertension in the Philippines, and it was projected in the next 30 years.

mHealth-Supported Gender- and Culturally Sensitive Weight Loss Intervention for Hispanic Men With Overweight and Obesity: Single-Arm Pilot Study.

Background: Hispanic men have disproportionate rates of overweight and obesity compared with other racial and ethnic subpopulations. However, few weight loss interventions have been developed specifically for this high-risk group. Furthermore, the use of mobile health (mHealth) technologies to support lifestyle behavior changes in weight loss interventions for Hispanic men is largely untested.

"Who is our real enemy?" internalized racism in the Puerto Rican diaspora and the role of political education within community health intervention.

Rationale: Puerto Ricans experience disproportionately high levels of emotional distress and co-occurring adverse health outcomes. Our study sought to elicit Puerto Rican men's perceptions of health disparities while centering dialogue on stressors, coping mechanisms, and general well-being. This paper focuses on one pronounced finding in our study, that of internalized racism and the effect it has on both individual well-being and intra-group cohesion.

Combined treatment with niclosamide and camptothecin enhances anticancer effect in U87 MG human glioblastoma cells.

Glioblastoma multiforme (GBM) is one of the deadliest cancers of the brain. Its ability to infiltrate healthy brain tissues renders it difficult to remove surgically. Furthermore, it exhibits high rates of radio- and chemoresistance, making the survival rates of patients with GBM poor.

Uncovering Historical Legacies to Contextualize Health Inequities in Puerto Rican Men: An Expansion of the Minority Stress Model.

Background: Low/no-income Latino men are disproportionately burdened by chronic disease morbidity and mortality, which is often compounded by persistent exposure to stress. Chronic stress is a key mediating factor in pathways linking macro-level socio-structural forces to micro-level behavioral factors with negative health outcomes. Being that Latinxs continue to be one of the fastest growing populations in the U.
