Posttraumatic stress disorder (PTSD) is highly comorbid with chronic pain conditions that often co-occur such as migraine headaches, temporomandibular disorder, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, chronic prostatitis/chronic pelvic pain syndrome, and tension headaches. Using a genetically informative sample, the current study evaluated the genetic and environmental factors contributing to the co-occurrence of PTSD and chronic pain conditions.
Data from 4680 male twins in the Vietnam Era Twin Registry were examined. Biometric modeling was used to estimate genetic and environmental variance components and genetic and environmental correlations between PTSD and multiple chronic pain conditions.
Heritabilities were estimated at 43% (95% confidence interval [CI] = 15%-63%) for PTSD and 34% (95% CI = 27%-41%) for the combined history of any one or more pain condition. buy Vismodegib Specific pain condition heritabilities ranged from 15% (95% CI = 0%-48%) for tension headaches to 41% (95% CI = 27%-54%) for migraine headaches. Environmental influences accounted for the remaining variance in pain conditions. The genetic correlation between PTSD and combined history of any one or more pain condition was rg= 0.61 (95% CI = 0.46-0.89) and ranged for individual pain conditions from rg= 0.44 (95% CI = 0.24-0.77) for migraine headache to rg= 0.75 (95% CI = 0.52-1.00) for tension headaches.
PTSD and chronic pain conditions are highly comorbid, and this relationship can be explained by both genetic and environmental overlap. The precise mechanisms underlying these relationships are likely diverse and multifactorial.

Elevated cardiovascular reactivity to, and reduced recovery from, challenging events may increase the risk of cardiovascular disease, and exercise training may reduce this reactivity. However, in a randomized controlled trial of aerobic versus strength training in sedentary, healthy young adults, we found no training group differences in reactivity or recovery. Because strength training also may have a reactivity-reducing effect, we conducted a secondary analysis of data from another trial, this time with a wait-list control condition.
One hundred nineteen healthy, young, sedentary adults were randomized to a 12-week aerobic training program or wait-list control. Before (T1) and after (T2) training and after 4 weeks of sedentary deconditioning (T3), we measured heart rate (HR), heart rate variability, and blood pressure at rest and in response to and recovery from psychological and orthostatic challenge. Data were analyzed using a group (aerobic versus wait-list) by session (T1, T2, and deconditioning) anancement of recovery as a cardioprotective mechanism of aerobic exercise training.Clinical Trial RegistrationClinicalTrials.gov Unique identifier NCT01335737.
This study raises further doubt about attenuation of cardiovascular reactivity or enhancement of recovery as a cardioprotective mechanism of aerobic exercise training.Clinical Trial RegistrationClinicalTrials.gov Unique identifier NCT01335737.
The experience of cancer elicits not only turmoil but also resilience in the family, which has been related to psychological adjustment and physical health of family caregivers. The biological pathways linking family cancer caregiving to health, however, remain poorly understood. This study examined the extent to which psychological risk and resilience factors related to a proinflammatory gene expression profile (conserved transcriptional response to adversity, or CTRA) among caregivers during the first-year postdiagnosis of a patient with colorectal cancer.
A total of 41 caregivers (mean age = 54 years, 74% female, 40% Hispanic) provided psychological data and peripheral blood samples around 4 and 12 months after diagnosis. Mixed regression models controlling for demographic and biometric factors were used to test the associations of caregiver CTRA gene expression with caregiving stress, loneliness, and lack of social support (risk factors), as well as benefit finding and meaning (resilience factors).
findings suggest that the development of new intervention strategies that prioritize reductions in caregiver loneliness may favorably impact biological mechanisms related to caregiver health.
The American Diabetes Association recently called for research on social and environmental determinants of diabetes to intensify primary prevention. Recent epidemiological evidence suggests that frequent and modifiable psychosocial stressors at work might contribute to the development of diabetes, but more prospective studies are needed. We evaluated the relationship between job strain and diabetes incidence in 12,896 workers followed up over a 13-year period in Ontario, Canada. We also examined the modifying effect of body mass index in this relationship.
Data from Ontario respondents (35-74 years of age) to the 2000-2001, 2002, and 2003 cycles of the Canadian Community Health Survey were prospectively linked to the Ontario Health Insurance Plan database for physician services and the Canadian Institute for Health Information Discharge Abstract Database for hospital admissions. The sample consisted of actively employed participants with no previous diagnosis for diabetes. Cox proportional hazard regressiisk group comprising women with obesity.
Currently, there is limited information on the level of apixaban in kidney transplant (KT) patients with atrial fibrillation (AF) and the influence of apixaban therapy on the level of immunosuppression and graft function.
This was a cross-sectional prospective study of 19 KT patients treated with apixaban. The levels of apixaban were measured using a chromogenic assay calibrated for apixaban and compared to those predicted by the manufacturer. Mean immunosuppression trough levels before and after apixaban treatment initiation were calculated using 3 consecutive measurements. Apixaban levels were compared to a historical control group comprising of 20 non-transplant patients with AF who were treated with the standard 5-mg bid apixaban dosage.
All KT patients should have been treated with the standard 5-mg bid apixaban dosage according to the clinical parameters; however, seven were inappropriately treated with a reduced dosage (2.5-mg bid). There was no significant difference in apixaban level between KT patients treated with the 5-mg bid dosage and non-transplant patients.
