Introduction: Osteoporosis is characterized by decreased bone mass and decreased bone quality, leading to increased bone fragility and risk of fractures. The number of fractures due to osteoporosis is projected to increase to over three million by the year 2025 and cost $25.3 billion annually. It ranks highly among diseases that cause patients to become bedridden with serious complications and reduced quality of life. Additionally, osteoporosis disproportionately affects Hispanics, which comprise most of the Rio Grande Valley (RGV) population. Therefore, our primary objective was to determine the prevalence of osteoporosis within the RGV. Additionally, we had secondary objectives to determine …

Background: Tau accumulation causes tauopathies and drives cellular senescence, which can lead to inflammation, neurodegeneration, and cognitive impairment. The association between intracellular tau deposition and pathogenesis has prompted therapeutic strategies that reduce tau expression. However, tau is also critical in microtubule stabilization, synaptic plasticity, and maintaining DNA integrity. We investigated the impact of tau removal on brain cell senescence and associated neurocognitive behaviors in aged tau knockout (Mapt0/0) and wild type control (Mapt+/+) mice. We also assessed physical, metabolic, histological, and biochemical outcomes in Mapt0/0 and Mapt+/+ mice and in response to …

Background: The SARS-CoV-2 coronavirus has been associated with structural brain changes, consistent with its neurological manifestations. Recent studies showed a specific predilection for brainstem glial activation and hypometabolism, possibly indicating involvement of the locus coeruleus. The locus coeruleus (LC) modulates many cognitive functions and behaviors and its norepinephrine projections regulate both immune responses and vascular reactivity. We aimed to examine differences in LC integrity between COVID-19 survivors and controls.
Method: Participants are enrolled across 3 US and 1 UK sites using harmonized cognitive and 7T MR-imaging protocols. Here, we analyzed data from 18 participants enrolled at Houston Methodist (12 COVID-19 …

The composition of resident microbes in the human body is linked to various diseases and their treatment outcomes. Although studies have identified pancreatic ductal adenocarcinoma (PDAC)-associated bacterial communities in the oral and gut samples, herein, we hypothesize that the prevalence of microbiota in pancreatic tumor tissues is different as compared with their matched adjacent, histologically normal appearing tissues, and these microbial molecular signatures can be highly useful for PDAC diagnosis/prognosis. In this study, we performed comparative profiling of bacterial populations in pancreatic tumors and their respective adjacent normal tissues using 16S rRNA-based metagenomics analysis. This study revealed a higher abundance …

A Bacille Calmette–Guérin (BCG) is still the only licensed vaccine for the prevention of tuberculosis, providing limited protection against Mycobacterium tuberculosis infection in adulthood. New advances in the delivery of DNA vaccines by electroporation have been made in the past decade. We evaluated the safety and immunogenicity of the DNA-hsp65 vaccine administered by intramuscular electroporation (EP) in cynomolgus macaques. Animals received three doses of DNA-hsp65 at 30-day intervals. We demonstrated that intramuscular electroporated DNA-hsp65 vaccine immunization of cynomolgus macaques was safe, and there were no vaccine-related effects on hematological, renal, or hepatic profiles, compared to the pre-vaccination parameters. No tuberculin …

Postpericardiotomy syndrome (PPS) is a known complication of cardiac valve surgery, but it has not been commonly reported as a postoperative complication of cardiac myxoma removal. A 78-year-old female with hypertension and atrial fibrillation presenting with angina was found to have a large left atrial myxoma (7.5 cm × 4.4 cm). The myxoma was resected; however, 1-week postoperation hemoglobin and blood pressure decreased with elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Limited transthoracic echocardiogram (TTE) showed moderate pericardial effusion, confirming the diagnosis of PPS. This case highlights the importance of monitoring patients postremoval of myxoma for symptoms of …

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most common chronic liver disease worldwide. Circadian disruptors, such as chronic jet lag (CJ), may be new risk factors for MAFLD development. However, the roles of CJ on MAFLD are insufficiently understood, with mechanisms remaining elusive. Studies suggest a link between gut microbiome dysbiosis and MAFLD, but most of the studies are mainly focused on gut bacteria, ignoring other components of gut microbes, such as gut fungi (mycobiome), and few studies have addressed the rhythm of the gut fungi. This study explored the effects of CJ on MAFLD and its related microbiotic …

Introduction
Less than one percent of individuals with a spinal cord injury (SCI) experience complete functional recovery by hospital discharge. In the majority of subjects with SCI or any significant neurological injury, functional impairments remain exceptionally devastating and are the leading causes of disability in the United States. Most subjects have impairments that span from paralysis, sensory and motor dysfunction. In the majority of cases, physical rehabilitation remains the hallmark intervention for the regain of function and improvement in the performance of activities of daily living (ADLs). However, rehabilitation can be limiting in that this method takes a considerable amount …

Background
The highest risk of depression is conveyed by insomnia. This risk can be mitigated by sleep interventions. Understanding brain mechanisms underlying increased emotional stability following insomnia treatment could provide insight relevant to the prevention of depression. Here, we investigated how different sleep interventions alter emotion-related brain activity in people with insomnia at high risk of developing depression.
Methods
Functional magnetic resonance imaging was used to assess how the amygdala response to emotional stimuli (negative facial expression) in 122 people with insomnia disorder differed from 36 control subjects and how the amygdala response changed after 6 weeks of either no …

Anchorage-independent survival after intravasation of cancer cells from the primary tumor site represents a critical step in metastasis. Here, we reveal new insights into how MUC13-mediated anoikis resistance, coupled with survival of colorectal tumor cells, leads to distant metastasis. We found that MUC13 targets a potent transcriptional coactivator, YAP1, and drives its nuclear translocation via forming a novel survival complex, which in turn augments the levels of pro-survival and metastasis-associated genes. High expression of MUC13 is correlated well with extensive macrometastasis of colon cancer cells with elevated nuclear YAP1 in physiologically relevant whole animal model systems. Interestingly, a positive correlation …

Background: Emerging evidence indicates that COVID-19 can negatively impact patient’s brain health (Douaud et al., 2022) (Cecchetti et al., 2022). Common clinical symptoms include brain fog, headaches, difficulty concentrating, and loss of sense of smell or taste. Some studies suggest that SARS-CoV-2 infection can damage the blood brain barrier either directly or through immune-inflammatory mechanisms (Zhang, et al. 2021). White matter hyperintensities (WMH) are imaging biomarkers of brain vascular or inflammatory injury. We investigated the association between severity of COVID-19 infection and burden of white matter hyperintensity volumes within a diverse multi-nation, multi-racial cohort using 7 Tesla (7T) MRI …

Background: Dementias are heterogeneous age-associated neurodegenerative disorders generally included in the broad term, Alzheimer’s disease (AD) and related dementias (ADRD). ADRD affects individuals of all ethnicities, but Hispanic individuals show a 1.5-fold higher risk when compared to non-Hispanic whites. Many AD risk biomarkers have been proposed but not much is known about how genetic elements control their expression. We used 2000 genome sequenced Mexican Americans from extended pedigrees to identify genetic regions associated with AD blood-based biomarkers.
Method: A total of 70 Mexican American subjects were diagnosed as ADRD cases (h2= 0.75, p = 2.6×10-5). We …

The traumatic pancreatoduodenectomy, also known as the traumatic Whipple, is a specialized surgical procedure often reserved for extreme cases in which an individual suffers traumatic injuries to the pancreas, duodenum, or periampullary structures. Traditionally, a Whipple procedure is a complex surgery involving the removal of the head of the pancreas, duodenum, and a portion of both the bile duct and stomach, for the management of pancreatic head cancer. In underserved communities where limited access to healthcare is coupled with a higher incidence of trauma, the lack of specialized and supportive care for patients suffering from pancreatic injuries may lead to …

In this case report, we discuss the presentation, diagnosis, and management of a 67-year-old gentleman with stage II multiple myeloma with concurrent biopsy-proven bone plasmacytoma and why it is important to understand the molecular intricacies of these disorders. We emphasize the critical role of radiology in identifying, characterizing, and managing these lesions. Furthermore, we shed light on the critical differentiation between solitary extramedullary plasmacytoma and multiple myeloma and discuss treatment modalities for both conditions.
