Administration of low intensity vibration and a RANKL inhibitor, alone or in combination, reduces bone loss after spinal cord injury-induced immobilization in rats.

We previously reported an ability of low-intensity vibration (LIV) to improve selected biomarkers of bone turnover and gene expression and reduce osteoclastogenesis but lacking of evident bone accrual. In this study, we demonstrate that a prolonged course of LIV that initiated at 2 weeks post-injury and continued for 8 weeks can protect against bone loss after SCI in rats. LIV stimulates bone formation and improves osteoblast differentiation potential of bone marrow stromal stem cells while inhibiting osteoclast differentiation potential of marrow hematopoietic progenitors to reduce bone resorption.

A novel methodology for emotion recognition through 62-lead EEG signals: multilevel heterogeneous recurrence analysis.

Objective: Recognizing emotions from electroencephalography (EEG) signals is a challenging task due to the complex, nonlinear, and nonstationary characteristics of brain activity. Traditional methods often fail to capture these subtle dynamics, while deep learning approaches lack explainability. In this research, we introduce a novel three-phase methodology integrating manifold embedding, multilevel heterogeneous recurrence analysis (MHRA), and ensemble learning to address these limitations in EEG-based emotion recognition.

Psilocybin desynchronizes the human brain.

A single dose of psilocybin, a psychedelic that acutely causes distortions of space-time perception and ego dissolution, produces rapid and persistent therapeutic effects in human clinical trials. In animal models, psilocybin induces neuroplasticity in cortex and hippocampus. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics.

Comorbidities in Hispanic/Latino Veterans with epilepsy.

Background: Hispanic/Latino people with epilepsy may be at a differential risk of medical and psychiatric comorbidities given genetic, environmental, sociocultural, and quality of care factors. In people with epilepsy, comorbidities are especially crucial to investigate given the well-known impact on quality of life and risk of adverse outcomes. Yet, Hispanic/Latino Veterans with Epilepsy (HL-VWE) remain an understudied population.

Videoconference-delivered group Cognitive Behavioral Stress Management for ME/CFS patients who present with severe PEM: A randomized controlled trial.

Background: In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), post-exertional malaise (PEM) is associated with greater distress and symptoms. Cognitive Behavioral Stress Management (CBSM) has demonstrated beneficial effects for ME/CFS and may mitigate stress-related triggers of PEM. We tested a virtual CBSM intervention to increase access, and we report on its effects on stress and symptoms in ME/CFS patients with severe PEM.

Characterizing 1991 Gulf War women veterans from the Boston Biorepository and Integrative Network for Gulf War Illness: Demographics, exposures, neuroimaging and cognitive outcomes.

: Gulf War Illness (GWI) is a debilitating multisymptom condition that affects nearly a third of 1990-91 Gulf War (GW) veterans. Symptoms include pain, fatigue, gastrointestinal issues, and cognitive decrements. Our work has shown that GWI rates and potential causes for symptoms vary between men and women veterans.

The prevalence of mild cognitive impairment in Gulf War veterans: a follow-up study.

Introduction: Gulf War Illness (GWI), also called Chronic Multisymptom Illness (CMI), is a multi-faceted condition that plagues an estimated 250,000 Gulf War (GW) veterans. Symptoms of GWI/CMI include fatigue, pain, and cognitive dysfunction. We previously reported that 12% of a convenience sample of middle aged (median age 52 years) GW veterans met criteria for mild cognitive impairment (MCI), a clinical syndrome most prevalent in older adults (e.

Cognitive decrements in 1991 Gulf War veterans: associations with Gulf War illness and neurotoxicant exposures in the Boston Biorepository, Recruitment, and Integrative Network (BBRAIN) cohorts.

Background: During deployment, veterans of the 1991 Gulf War (GW) were exposed to multiple war-related toxicants. Roughly a third of these veterans continue to exhibit neurotoxicant induced symptoms of Gulf War Illness (GWI), a multi-faceted condition that includes fatigue, pain and cognitive decrements. When studied empirically, both deployed veterans with exposures and those who meet the criteria for GWI are more likely to show deficits in the area of neuropsychological functioning.

The Tripartite Model of Depression in Schizophrenia and Bipolar Disorder: A Secondary Analysis.

Models of affect, like the tripartite model, suggest that positive affect (PA) and negative affect (NA) are independent between subjects and negatively correlated within. Correlations may differ in bipolar disorder (BD) and schizophrenia. Using ecological momentary assessment (EMA) and clinical ratings, this secondary analysis evaluated the tripartite model by examining PA and NA.

The environment and dry eye-manifestations, mechanisms, and more.

Dry eye disease (DED) is a multifactorial condition that often presents with chronic symptoms of pain (that can be characterized as "dryness," "burning," and "irritation," to name a few) and/or fluctuating or poor-quality vision. Given its multifactorial nature, several pathophysiologic mechanisms have been identified that can underlie symptoms, including tear film, ocular surface, and/or corneal somatosensory nerve abnormalities. Research has focused on understanding how environmental exposures can increase the risk for DED flares and negatively impact the tear film, the ocular surface, and/or nerve health.

A Review of Clinical Signs and Symptoms of Imminent End-of-Life in Individuals With Advanced Illness.

World population is not only aging but suffering from serious chronic illnesses, requiring an increasing need for end-of-life care. However, studies show that many healthcare providers involved in the care of dying patients sometimes express challenges in knowing when to stop non-beneficial investigations and futile treatments that tend to prolong undue suffering for the dying person. To evaluate the clinical signs and symptoms that show end-of-life is imminent in individuals with advanced illness.

Genetic association between the APOE ε4 allele, toxicant exposures and Gulf war illness diagnosis.

Introduction: Exposure to nerve agents, pyridostigmine bromide (PB), pesticides, and oil-well fires during the 1991 Gulf War (GW) are major contributors to the etiology of Gulf War Illness (GWI). Since the apolipoprotein E (APOE) ε4 allele is associated with the risk of cognitive decline with age, particularly in the presence of environmental exposures, and cognitive impairment is one of the most common symptoms experienced by veterans with GWI, we examined whether the ε4 allele was associated with GWI.

Methods: Using a case-control design, we obtained data on APOE genotypes, demographics, and self-reported GW exposures and symptoms that were deposited in the Boston Biorepository and Integrative Network (BBRAIN) for veterans diagnosed with GWI (n = 220) and healthy GW control veterans (n = 131).

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Psychotic Disorders: I. Clinical Outcomes.

Background: Social determinants of health (SDoHs) are receiving growing attention and are particularly relevant to persons with schizophrenia-spectrum psychotic disorders (SSPDs), considering their heightened risk of comorbidities, cognitive and functional decline, and early mortality. Yet, we did not find any comprehensive review of multiple SDoHs in SSPD.

Study Design: We conducted a scoping review of meta-analyses and systematic reviews of nine major SDoHs in SSPD.

Impact of Tumor Necrosis Factor Receptor 1 () Polymorphism on Dry Eye Disease.

The goal of the study was to examine whether a genetic polymorphism in tumor necrosis factor receptor 1 () gene impacted the dry eye disease (DED) phenotype and response to anti-inflammatory therapy. The prospective study included 328 individuals with various dry eye (DE) symptoms and signs recruited from the Miami Veterans Hospital eye clinic between October 2013 and October 2017. The population underwent genetic profiling for a polymorphism within the gene (rs1800693 [TT, TC, CC]).

Deficient butyrate-producing capacity in the gut microbiome is associated with bacterial network disturbances and fatigue symptoms in ME/CFS.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by unexplained debilitating fatigue, cognitive dysfunction, gastrointestinal disturbances, and orthostatic intolerance. Here, we report a multi-omic analysis of a geographically diverse cohort of 106 cases and 91 healthy controls that revealed differences in gut microbiome diversity, abundances, functional pathways, and interactions. Faecalibacterium prausnitzii and Eubacterium rectale, which are both recognized as abundant, health-promoting butyrate producers in the human gut, were reduced in ME/CFS.

Time-course and convergence of positive and negative moods in participants with schizophrenia: An ecological momentary assessment study.

Introduction: Many people with schizophrenia report low levels of negative affect (NA), which may reflect biases in emotion processing. In the general population there is an inverse correlation between positive affect (PA) and NA. It is possible that this relationship is different among people with schizophrenia.

Primary Biliary Cholangitis in Males: Pathogenesis, Clinical Presentation, and Prognosis.

Primary biliary cholangitis (PBC) is an immune-mediated chronic liver disease characterized by progressive cholestasis, bile duct destruction, biliary fibrosis, and cirrhosis. Patients who respond to ursodeoxycholic acid have an expected survival similar to the general population. Although PBC primarily affects females, the prevalence in males is higher than was previously believed, with contemporary studies suggesting a female-to-male ratio of 4-6:1.

The authors review the current domains of technology utilization, describe standards for quality evaluation, and forecast future developments.

Challenges in initiating a lung cancer screening program: Experiences from two VA medical centers.

Establishing a lung cancer screening (LCS) program is an important endeavor that delivers life-saving healthcare to an at-risk population. However, developing a comprehensive LCS program requires critical elements including obtaining institutional level buy-in, hiring necessary personnel, developing appropriate infrastructure and actively engaging primary care providers, subspecialty services, and radiology. The process required to connect such services to deliver an organized LCS program that reaches all eligible candidates must be individualized to each institution's needs and infrastructure.
