To compare the severity of posttraumatic stress disorder (PTSD) symptoms and of particular PTSD clusters among help-seeking veterans before and during the COVID-19 lockdown. The second aim was to identify the main coping strategies used.

Male war veterans (N=176) receiving outpatient treatment at the Referral Center for PTSD were assessed at baseline (12-18 months before the pandemic declaration in March 2020) and during the COVID-19 pandemic lockdown (March-June 2020). The Life Events Checklist for DSM-5, PTSD Checklist for DSM-5, and The Brief COPE were used.

Direct exposure to the virus in our sample was low, and the majority of participants followed the preventive measures. The severity of the overall PTSD symptoms and of clusters of symptoms significantly decreased compared with the first assessment. At the second assessment, all participants still fulfilled the PTSD diagnosis criteria. During the lockdown, the participants used emotion-focused and problem-focused coping rather than dysfunctional coping.

The severity of PTSD symptoms decreased during the lockdown. Further research is needed to study the trajectories of long-term psychopathology.

To evaluate the consumption of remifentanil (as a primary end-point), analgesia, sedation, hemodynamics, respiratory effects, and surgeon and patient satisfaction (as a secondary end-point) with dexmedetomidine sedation compared with those of remifentanil sedation in patients undergoing vitreoretinal surgery.

Patients subjected to retinal ophthalmic surgical procedures were randomized to one of two intraoperative sedation groups one group (n=21) received intranasal dexmedetomidine plus intravenous remifentanil (DEX-REMI group), and the other group (n=19) received intravenous remifentanil only (REM group). The treatment was placebo-controlled. The sedation level was controlled according to the bispectral index, with target values between 80%-90%. Patient levels of comfort, sedation, and pain were documented. The number of intraoperative complications and the level of satisfaction were assessed. Remifentanil consumption and hemodynamic parameters were also included in the statistical analysis.

The level of remifentanil consumption was significantly lower in the DEX-REMI group, but combination sedation improved the surgeon's, anesthesiologist's, and patients' satisfaction scores. Importantly, the number of complications was zero in the DEX-REMI group, while eight cases of complications were noted in the REM group. The DEX-REMI group showed lower mean minimal arterial pressure, but it was still in the normotensive range.

For patients undergoing ophthalmic procedures, sedation with a combination of intranasal dexmedetomidine and an intravenous infusion of remifentanil provides lower remifentanil consumption, better satisfaction scores, and a lower complication rate than sedation with a remifentanil infusion alone.

To perform a mutation analysis of FK506 binding protein-like (FKBPL) in patients with azoospermia.

DNA samples were isolated from the peripheral blood of 30 azoospermic male patients with normal 46 XY karyotype and 10 healthy controls. Multiplex polymerase chain reaction assays were used to evaluate Y microdeletions, and the patients without deletions were further analyzed. Sanger sequencing was used for mutation analysis.

A heterozygous adenine to guanine substitution was observed at position c.28 (c.28A>G) (one patient), guanine to adenine substitution at c.90 (c.90G>A) (three patients), and a novel insertion mutation of TCTCATAAGTCT at c. 229_240dup (two patients), all in FKBPL exon 2. Furthermore, four different benign variants were observed in the same gene.

Our study supports the literature on the etiologic effects of changes on autosomal chromosomes and highlights the importance of molecular analysis of all known and unknown genes that could be involved in male sexual development and function.

To determine the effects of metformin or liraglutide on oxidative stress level and antioxidative enzymes gene expression and activity in the blood and vessels of pre-diabetic obese elderly Sprague-Dawley (SD) rats of both sexes.

Male and female SD rats were assigned to the following groups a) control group (fed with standard rodent chow); b) high-fat and high-carbohydrate diet (HSHFD) group fed with HSHFD from 20-65 weeks of age; c) HSHFD+metformin treatment (50 mg/kg/d s.c.); and d) HSHFD+liraglutide treatment (0.3 mg/kg/d s.c). Oxidative stress parameters (ferric reducing ability of plasma and thiobarbituric acid reactive substances) and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activity and gene expression were determined from serum, aortas, and surface brain blood vessels (BBV).

HSHFD increased body weight in both sexes compared with the control group, while liraglutide prevented this increase. Blood glucose level did not change. selleckchem The liraglutide group had a significantly increased antioxidative capacity compared with the HSHFD group in both sexes. The changes in antioxidative enzymes' activities in plasma were more pronounced in male groups. The changes in antioxidative gene expression were more prominent in microvessels and may be attributed to weight gain prevention.

Obesity and antidiabetic drugs caused sex-related differences in the level of antioxidative parameters. Liraglutide exhibited stronger antioxidative effects than metformin. These results indicate that weight gain due to HSHFD is crucial for developing oxidative stress and for inhibiting antioxidative protective mechanisms.
