Accelerometer-Measured Behavior Patterns in Incident Cerebrovascular Disease: Insights for Preventative Monitoring From the UK Biobank. J Am Heart Assoc 2024; 13:e032965. [PMID: 38818948 PMCID: PMC11255632 DOI: 10.1161/jaha.123.032965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 04/03/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND The goal was to compare patterns of physical activity (PA) behaviors (sedentary behavior [SB], light PA, moderate-to-vigorous PA [MVPA], and sleep) measured via accelerometers for 7 days between patients with incident cerebrovascular disease (CeVD) (n=2141) and controls (n=73 938). METHODS AND RESULTS In multivariate models, cases spent 3.7% less time in MVPA (incidence rate ratio [IRR], 0.963 [95% CI, 0.929-0.998]) and 1.0% more time in SB (IRR, 1.010 [95% CI, 1.001-1.018]). Between 12 and 24 months before diagnosis, cases spent more time in SB (IRR, 1.028 [95% CI, 1.001-1.057]). Within the year before diagnosis, cases spent less time in MVPA (IRR, 0.861 [95% CI, 0.771-0.964]). Although SB time was not associated with CeVD risk, MVPA time, both total min/d (hazard ratio [HR], 0.998 [95% CI, 0.997-0.999]) and guideline threshold adherence (≥150 min/wk) (HR, 0.909 [95% CI, 0.827-0.998]), was associated with decreased CeVD risk. Comorbid burden had a significant partial mediation effect on the relationship between MVPA and CeVD. Cases slept more during 12:00 to 17:59 hours (IRR, 1.091 [95% CI, 1.002-1.191]) but less during 0:00 to 5:59 hours (IRR, 0.984 [95% CI, 0.977-0.992]). No between-group differences were significant at subgroup analysis. CONCLUSIONS Daily behavior patterns were significantly different in patients before CeVD. Although SB was not associated with CeVD risk, the association between MVPA and CeVD risk is partially mediated by comorbid burden. This study has implications for understanding observable behavior patterns in cerebrovascular dysfunction and may help in developing remote monitoring strategies to prevent or reduce cerebrovascular decline.

Abstract
Background The clinical correlation between erectile dysfunction (ED) and depression has been revealed in cumulative studies. However, the evidence of shared mechanisms between them was insufficient. This study aimed to explore common transcriptomic alterations associated with ED and depression. Materials and methods The gene sets associated with ED and depression were collected from the Gene Expression Omnibus (GEO) database. Comparative analysis was conducted to obtain common genes. Using R software and other appropriate tools, we conducted a range of analyses, including function enrichment, interactive network creation, gene cluster analysis, and transcriptional and post-transcriptional signature profiling. Candidate hub crosslinks between ED and depression were selected after external validation and molecular experiments. Furthermore, subpopulation location and disease association of hub genes were explored. Results A total of 85 common genes were identified between ED and depression. These genes strongly correlate with cell adhesion, redox homeostasis, reactive oxygen species metabolic process, and neuronal cell body. An interactive network consisting of 80 proteins and 216 interactions was thereby developed. Analysis of the proteomic signature of common genes highlighted eight major shared genes: CLDN5, COL7A1, LDHA, MAP2K2, RETSAT, SEMA3A, TAGLN, and TBC1D1. These genes were involved in blood vessel morphogenesis and muscle cell activity. A subsequent transcription factor (TF)-miRNA network showed 47 TFs and 88 miRNAs relevant to shared genes. Finally, CLDN5 and TBC1D1 were well-validated and identified as the hub crosslinks between ED and depression. These genes had specific subpopulation locations in the corpus cavernosum and brain tissue, respectively. Conclusion Our study is the first to investigate common transcriptomic alterations and the shared biological roles of ED and depression. The findings of this study provide insights into the referential molecular mechanisms underlying the co-existence between depression and ED.

Plasma Endostatin Levels at Acute Phase of Ischemic Stroke Are Associated with Post-Stroke Cognitive Impairment. Neurotox Res 2020; 37:956-964. [PMID: 32034697 DOI: 10.1007/s12640-020-00173-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 01/29/2020] [Accepted: 01/31/2020] [Indexed: 12/25/2022]
Abstract
The effect of plasma endostatin on cognitive impairment after ischemic stroke remains unclear. We conducted this study to explore the association between plasma endostatin in the acute phase of ischemic stroke and post-stroke cognitive impairment (PSCI). Baseline plasma endostatin levels were measured, and cognitive function status was assessed by Montreal cognitive assessment at 3 months among 613 ischemic stroke patients. PSCI was defined as Montreal cognitive assessment score less than 26. The association of endostatin with PSCI was analyzed by logistic regression model. The receiver operating characteristic curve was applied to explore the optimal cutoff value of plasma endostatin levels in predicting PSCI. In a multivariable-adjusted model, the odds ratio for the highest vs lowest quartile of endostatin was 2.01 (95% CI, 1.15-3.53) for PSCI. Restricted cubic spline regression model showed a linear dose-response association between endostatin and PSCI (p for linearity = 0.01). The optimal cut point of endostatin was 84.22 ng/mL; higher endostatin levels (≥ 84.22 ng/mL) were associated with increased risk of 2.17-fold for PSCI (adjusted odds ratio, 2.17; 95% CI, 1.44-3.26; p = 0.0002). Furthermore, adding endostatin to a model containing conventional factors led to significant reclassification for PSCI (net reclassification improvement, 0.20; p = 0.025; integrated discrimination improvement, 0.016; p = 0.002). Our findings showed that elevated plasma endostatin levels were associated with cognitive impairment at 3 months after acute ischemic stroke, independently of established conventional risk factors, suggesting that endostatin may be an important biomarker of cognitive impairment after ischemic stroke.

Abstract
OBJECTIVES To (1) describe the prevalence of psychiatric illness in fracture patients ≥70 years of age and (2) investigate the association between psychiatric illness and complications requiring unplanned readmission in elderly patients. DESIGN Retrospective cohort study. PATIENTS/PARTICIPANTS One thousand one hundred eighty-six patients ≥70 years of age with surgically treated fractures and ≥1-month follow-up treated from 2012 to 2017. INTERVENTION None. MAIN OUTCOME MEASURE Complication requiring unplanned readmission. RESULTS Forty-four percent of patients ≥70 years of age have psychiatric comorbidities, and of those, 34% had >1 diagnosis. There was a higher rate of readmission among patients with psychiatric diagnosis compared with those without psychiatric diagnosis (35% vs. 21%, P < 0.001). There was a higher prevalence of psychiatric illness among patients 70 years of age or older compared with patients less than 70 years of age (44% vs. 39%, P = 0.007). Multivariate regression analysis controlling for age, sex, Charlson Comorbidity Index, dementia, delirium during admission, tobacco use, substance abuse, Injury Severity Score, fracture location, number of procedures, and number of fractures demonstrated an independent association between psychiatric illness and unplanned readmission (adjusted OR 1.54, 95% confidence interval, 1.15-2.07, P = 0.003). CONCLUSIONS Almost half of the elderly patients in the present cohort have psychiatric comorbidities. Furthermore, psychiatric illness is an independent predictor of unplanned readmission, which may have substantial consequences for recovery and cost of care. This emphasizes the need for more attention to these issues in geriatric patient populations and the need to identify means to influence the downstream consequences of these comorbidities. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
There is tremendous recent interest in chronic traumatic encephalopathy (CTE) in former collision sport athletes, civilians, and military veterans. This critical review places important recent research results into a historical context. In 2015, preliminary consensus criteria were developed for defining the neuropathology of CTE, which substantially narrowed the pathology previously reported to be characteristic. There are no agreed upon clinical criteria for diagnosis, although sets of criteria have been proposed for research purposes. A prevailing theory is that CTE is an inexorably progressive neurodegenerative disease within the molecular classification of the tauopathies. However, historical and recent evidence suggests that CTE, as it is presented in the literature, might not be pathologically or clinically progressive in a substantial percentage of people. At present, it is not known whether the emergence, course, or severity of clinical symptoms can be predicted by specific combinations of neuropathologies, thresholds for accumulation of pathology, or regional distributions of pathologies. More research is needed to determine the extent to which the neuropathology ascribed to long-term effects of neurotrauma is static, progressive, or both. Disambiguating the pathology from the broad array of clinical features that have been reported in recent studies might facilitate and accelerate research- and improve understanding of CTE.

Abstract
Brain gene expression profiling studies of suicide and depression using oligonucleotide microarrays have often failed to distinguish these two phenotypes. Moreover, next generation sequencing approaches are more accurate in quantifying gene expression and can detect alternative splicing. Using RNA-seq, we examined whole-exome gene and exon expression in non-psychiatric controls (CON, N=29), DSM-IV major depressive disorder suicides (MDD-S, N=21) and MDD non-suicides (MDD, N=9) in the dorsal lateral prefrontal cortex (Brodmann Area 9) of sudden death medication-free individuals post mortem. Using small RNA-seq, we also examined miRNA expression (nine samples per group). DeSeq2 identified 35 genes differentially expressed between groups and surviving adjustment for false discovery rate (adjusted P<0.1). In depression, altered genes include humanin-like-8 (MTRNRL8), interleukin-8 (IL8), and serpin peptidase inhibitor, clade H (SERPINH1) and chemokine ligand 4 (CCL4), while exploratory gene ontology (GO) analyses revealed lower expression of immune-related pathways such as chemokine receptor activity, chemotaxis and cytokine biosynthesis, and angiogenesis and vascular development in (adjusted P<0.1). Hypothesis-driven GO analysis suggests lower expression of genes involved in oligodendrocyte differentiation, regulation of glutamatergic neurotransmission, and oxytocin receptor expression in both suicide and depression, and provisional evidence for altered DNA-dependent ATPase expression in suicide only. DEXSEq analysis identified differential exon usage in ATPase, class II, type 9B (adjusted P<0.1) in depression. Differences in miRNA expression or structural gene variants were not detected. Results lend further support for models in which deficits in microglial, endothelial (blood-brain barrier), ATPase activity and astrocytic cell functions contribute to MDD and suicide, and identify putative pathways and mechanisms for further study in these disorders.

Abstract
BACKGROUND Psychiatric disorders are common, and their functional consequences may be underappreciated by non-mental health-care providers. There exist limited data regarding the frequency of psychiatric illness in patients who sustain orthopaedic polytrauma. The purpose of this study was to describe the prevalence of psychiatric illness in patients with orthopaedic polytrauma, to determine whether psychiatric illnesses were identified and were accommodated by trauma providers, and, finally, to investigate any associations between postoperative complications and psychiatric illness. METHODS Three hundred and thirty-two skeletally mature patients with surgically treated axial and/or femoral fractures and injuries to other body systems (Injury Severity Score of ≥ 16 points) were identified from a database at a Level-I trauma center. These included 238 men and ninety-four women with a mean value (and standard deviation) of 39 ± 16 years for age and 27 ± 12 points for the Injury Severity Score. Records were reviewed for preexisting diagnoses of psychiatric disorders. The inpatient courses and discharge recommendations regarding treatment of psychiatric illness were analyzed. Complications in the six-month postoperative period were determined by an independent committee. RESULTS Preexisting psychiatric disorders were identified in 130 patients (39.2%), including depression in seventy-four patients (22.3%) and substance abuse in fifty-six patients (16.9%). Patients managed by an orthopaedic surgery service were less likely to receive their home psychiatric medications while hospitalized (p = 0.001) and were less likely to receive instructions for psychiatric follow-up at discharge (p = 0.087). Postoperative complications occurred in sixty-six patients (19.9%) overall; depression was an independent predictor of increased complications, with an odds ratio of 2.956 (95% confidence interval, 1.502 to 5.816). CONCLUSIONS Psychiatric illness was common among individuals who sustained orthopaedic polytrauma, and patients with depression had more complications. This study highlights the need for greater attention to mental health disorders in this population.

Abstract
Functional imaging studies consistently report abnormal amygdala activity in major depressive disorder (MDD). Neuroanatomical correlates are less clear: imaging studies have produced mixed results on amygdala volume, and postmortem neuroanatomic studies have only examined cell densities in portions of the amygdala or its subregions in MDD. Here, we present a stereological analysis of the volume of, and the total number of, neurons, glia, and neurovascular (pericyte and endothelial) cells in the basolateral amygdala in MDD. Postmortem tissues from 13 subjects with MDD and 10 controls were examined. Sections (~15/subject) taken throughout the rostral-caudal extent of the basolateral amygdala (BLA) were stained for Nissl substance and utilized for stereological estimation of volume and cell numbers. Results indicate that depressed subjects had a larger lateral nucleus than controls and a greater number of total BLA neurovascular cells than controls. There were no differences in the number or density of neurons or glia between depressed and control subjects. These findings present a more detailed picture of BLA cellular anatomy in depression than has previously been available. Further studies are needed to determine whether the greater number of neurovascular cells in depressed subjects may be related to increased amygdala activity in depression.
