Objective: Depression is associated with some alterations in behavior and hypothalamic-pituitary-adrenal axis function that may be risk factors for decreased bone mineral density (BMD). There is considerable inconsistency as to whether depressed patients really have decreased BMD or not. Decreased BMD has been reported in patients suffering from major depression in some studies, but not in some others. Moreover, few studies have investigated BMD in male depressed patients. The aim of this study was to investigate BMD in patients with major depression, including male ones.
Method: BMD was investigated in forty-two inpatients that fully met the DSM-IV criteria for major depressive disorder (21 women, 21 men; mean age+/-SD: 37.57+/-8.70) and compared with that in twenty-three healthy controls (12 women, 11 men; mean age+/-SD: 33.73+/-7.16). The severity of clinical symptomatology was assessed by the Montgomery-Asberg Depression Rating Scale (MADRS). BMDs of lumbar vertebrae (L1-L4) and femur neck were measured using dual energy X-ray absorptiometry.
Results: We found no difference in the values of BMDs of lumbar vertebra (L1-L4) and femur neck between depressive patients and controls among women or men. However, BMDs of the males in the control group were higher than those of the healthy females for both regions investigated; this gender difference was not observed in the depressive patients.
Conclusion: Major depression is not associated with any alteration in BMD either in women or in men.

Some patients with metastatic castration-resistant prostate cancer (mCRPC) possess germline or acquired defects in the DNA damage repair (DDR) genes BRCA1 and BRCA2. Tumors with BRCA mutations exhibit sensitivity to poly-ADP ribose polymerase inhibitors (PARPi) such as olaparib and rucaparib. As a result, molecular diagnostic testing to identify patients with BRCA mutations eligible for the PARPi therapy has become an integral component of managing patients with mCRPC.

Background: Spinal cord (SC) atrophy is a key imaging biomarker of progressive multiple sclerosis (MS). Progressive MS is more common in men and postmenopausal women.
Objective: Investigate the impact of sex and menopause on SC measurements in persons with MS (pwMS).

Greater neighborhood disadvantage is associated with poorer global cognition. However, less is known about the variation in the magnitude of neighborhood effects across individual cognitive domains and whether the strength of these associations differs by individual-level factors. The current study investigated these questions in a community sample of older adults ( = 166, mean age = 72.

Background: A recent prospective phase II study (ECOG-ACRIN E2211) demonstrated that MGMT deficiency was associated with a significant response to capecitabine and temozolomide (CAPTEM) in pancreatic neuroendocrine neoplasms (NENs); however, routine MGMT analysis in NENs was not recommended. Our study sought to demonstrate whether loss of MGMT protein expression is associated with improved overall survival (OS) in patients receiving CAPTEM for NENs from various tumor sites.
Materials And Methods: Paraffin-embedded tumor samples were evaluated by immunohistochemistry (IHC) using an MGMT monoclonal antibody.

Background: Advanced pancreatic ductal adenocarcinoma (aPDAC) is often accompanied by significant muscle mass loss, contributing to poor prognosis. SarcAPACaP, an ancillary study of the GERCOR-APACaP phase III trial, evaluated the role of adapted physical activity (APA) in aPDAC Western patients receiving first-line chemotherapy. The study aimed to assess (1) the potential impact of computed tomography (CT)-quantified muscle mass before and during treatments on health-related quality of life (HRQoL) and overall survival (OS) and (2) the role of APA in mitigating muscle mass loss.
