Transcriptomic and clonal characterization of #T cells in the human central #nervous system

T cells provide critical immune surveillance to the central nervous system (CNS), and the cerebrospinal fluid (CSF) is thought to be a main route for their entry. Further characterization of the state of T cells in the CSF in healthy individuals is important for understanding how T cells provide protective immune surveillance without damaging the… Continue reading Transcriptomic and clonal characterization of #T cells in the human central #nervous system

Randomized Trial of Nocturnal #Oxygen in Chronic #Obstructive Pulmonary Disease

Long-term oxygen therapy improves survival in patients with chronic obstructive pulmonary disease (COPD) and chronic severe daytime hypoxemia. However, the efficacy of oxygen therapy for the management of isolated nocturnal hypoxemia is uncertain.. ..Patients with an oxygen saturation of less than 90% for at least 30% of the recording time on nocturnal oximetry were assigned,… Continue reading Randomized Trial of Nocturnal #Oxygen in Chronic #Obstructive Pulmonary Disease

#Depression and subsequent risk for incident rheumatoid #arthritis among women

We investigated the association of depression with subsequent risk of rheumatoid arthritis (RA) by serologic phenotype.. ..Among 195,358 women, we identified 858 incident RA cases (65% seropositive) over 3,087,556 person‐years (median 17.9 years/participant). Compared to women without depression, those with depression had multivariable HRs (95%CIs) of: 1.28(1.10‐1.48) for all RA; 1.12(0.93‐1.35) for seropositive RA; and… Continue reading #Depression and subsequent risk for incident rheumatoid #arthritis among women

Association of #Coffee Intake With Survival in Patients With Advanced or Metastatic #Colorectal Cancer

Several compounds found in coffee possess antioxidant, anti-inflammatory, and insulin-sensitizing effects, which may contribute to anticancer activity. Epidemiological studies have identified associations between increased coffee consumption and decreased recurrence and mortality of colorectal cancer. The association between coffee consumption and survival in patients with advanced or metastatic colorectal cancer is unknown.. ..Among the 1171 patients… Continue reading Association of #Coffee Intake With Survival in Patients With Advanced or Metastatic #Colorectal Cancer

Increased risk of acute #stroke among patients with severe #COVID‐19: a multicenter study and meta‐analysis

Recent observations linked coronavirus disease 2019 (COVID‐19) to thromboembolic complications possibly mediated by increased blood coagulability and inflammatory endothelial impairment. We aimed to define the risk of acute stroke in patients with severe and non‐severe COVID‐19.. ..Of 165 patients hospitalized for COVID‐19 (49.1% males, median age 67 [57‐79], 72.1% severe or critical) included in the… Continue reading Increased risk of acute #stroke among patients with severe #COVID‐19: a multicenter study and meta‐analysis

Chromatin accessibility mapping of the striatum identifies tyrosine kinase FYN as a therapeutic target for #heroin use disorder

The current opioid epidemic necessitates a better understanding of human addiction neurobiology to develop efficacious treatment approaches. Here, we perform genome-wide assessment of chromatin accessibility of the human striatum in heroin users and matched controls. Our study reveals distinct neuronal and non-neuronal epigenetic signatures, and identifies a locus in the proximity of the gene encoding… Continue reading Chromatin accessibility mapping of the striatum identifies tyrosine kinase FYN as a therapeutic target for #heroin use disorder

Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Recent studies suggested that higher BMI and serum urate levels were associated with lower risk of developing dementia. However, these reverse relationships remain controversial, and whether serum urate and BMI confound each other is not well established.. ..During a median of 8.1 years of follow-up, a total of 2138 participants developed dementia. People who were… Continue reading Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Post-traumatic stress disorder as a risk factor for #dementia: systematic review and meta-analysis

Post-traumatic stress disorder (PTSD) has been identified as a potential risk factor for developing dementia. There are currently, however, no meta-analyses quantifying this risk.. ..PTSD was associated with a significant risk for all-cause dementia: pooled hazard ratio HR = 1.61 (95% CI 1.43–1.81, I2= 85.8%, P < 0.001; n = 1 693 678; 8 studies).… Continue reading Post-traumatic stress disorder as a risk factor for #dementia: systematic review and meta-analysis

#Aspirin use and risk of #breast cancer in African American women

Use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) has been hypothesized to be associated with reduced risk of breast cancer; however, results of epidemiological studies have been mixed. Few studies have investigated these associations among African American women.. To assess the relation of aspirin use to risk of breast cancer in African American women,… Continue reading #Aspirin use and risk of #breast cancer in African American women
