Effect of Electroconvulsive Therapy on Anxiety in Linear and Non-Linear Rats with Depressive-Like Disorders Induced by Ultrasound Stimulation

Bulletin of Experimental Biology and Medicine - We performed a comparative study of the effect of electroconvulsive therapy on anxiety in outbred rats and Sprague-Dawley rats with depressive-like...     

Extracapsular extension in oral cavity cancers—predictive factors and impact on recurrence pattern and survival

Extracapsular extension (ECE) has long been considered a poor prognostic factor in oral cavity cancer, the presence of which warrants intensification of adjuvant therapy. This study was done to analyze the survival of patients with ECE who received adjuvant chemoradiation. Patients with pathologically confirmed squamous cell carcinoma of the oral cavity, with a minimum of 2 years of follow-up, who were treated at a tertiary cancer centre in New Delhi, India during the years 2009–2017, were included. On multivariate analysis, ECE was significantly associated with depth of invasion >10 mm and tumour deposit size >5 mm. Among the node-positive group, patients without ECE had a 5-year disease-free survival (DFS) and 5-year overall survival (OS) advantage over ECE-positive patients of 7.8% (63.8% vs. 56.0%) and 16.5% (87.2% vs. 70.7%), respectively. For patients with ECE, the hazard ratio for DFS and OS was 1.3 (95% confidence interval 0.97–1.75, P = 0.078) and 2.30 (95% confidence interval 1.35–3.92, P = 0.002), respectively. ECE remains one of the strongest predictors of recurrence and survival in oral cancer patients, and despite aggressive adjuvant therapy, distant recurrence is still significantly high.     

Detection of crevasses by geomorphometric treatment of data from unmanned aerial surveys

For Antarctic research, one of the important support tasks is a monitoring of sledge routes and other visited areas for detection of open crevasses and revealing of hidden, snow-covered ones. We study the possibility of revealing hidden crevasses with geomorphometric treatment of high-resolution, glacier digital elevation models (DEMs) produced from imagery captured by unmanned aerial systems (UASs). The study was conducted in East Antarctica, at a sledge route from the Progress to Vostok Stations. The survey performed with Geoscan 201 Geodesy UAS, resulted in a set of aerial images with a resolution of 6 cm. From these images, we produced glacier DEMs for a typical area with snow-covered crevasses. The glacier DEMs with the resolutions of 25 cm, 50 cm, and 1 m were treated by geomorphometric methods. We derived models of 16 morphometric variables including horizontal and vertical curvatures. For the 1-m gridded DEM, mapping of some variables allowed us to reveal one of the crevasses. The approach is functional, at least, for revealing crevasses with a width of 1.5 m and wider, covered by the snow layer with a thickness of up to 1.2 m.     

Fertility Outcome After Renal Transplantation: A Single-Center Experience

BackgroundWomen suffering from kidney disease are more prone to fertility problems, due to uremia. Fortunately, their fertility rate increases dramatically after renal transplantation. This study analyzes the predictors/risk factors of successful pregnancy with live birth outcome while presenting an overview of the 7-year experience of a single center.MethodsThis retrospective cohort study includes 239 women of reproductive age (18–40 years) who underwent renal transplantation in a tertiary Turkish clinic between October 1, 2011, and August 24, 2017. The subjects were invited to take part in a survey questioning their obstetric characteristics and they were assessed in 2 groups: fertile and infertile. Multivariable linear regression analysis was conducted to determine the predictors of a successful pregnancy.ResultsThirty-five 35 patients wished to become pregnant: 12 got pregnant spontaneously, while 21 failed to become pregnant (spontaneously). The mean age of the patients at the survey was 34 ± 7. Regular menstrual cycles after renal transplantation, tacrolimus-mycophenolate mofetil maintenance protocol, and age at transplantation were found to be predictors of spontaneous pregnancy. The duration of peritoneal dialysis was significantly longer in the infertile group (48 vs 12 months).ConclusionEnd-stage renal disease's negative impacts, including menstrual abnormality and fertility problems, can be overcome by successful kidney transplantation with appropriate immunosuppression. Minimizing the duration of peritoneal dialysis, particularly in patients who desire future fertility, may be accepted as a logical management strategy.     

A slime of the times: Two cases of acute irritant contact dermatitis from homemade slime

We describe two cases of acute‐onset erythema, peeling, and pruritus or tenderness isolated to the palmar surface of the hands. A detailed exposure history revealed significant periods of contact with homemade slime; given the clinical findings and timing of exposure, acute contact dermatitis of the hands was suspected. Symptoms and clinical findings resolved after avoidance of the suspected causative contactants. There are few if any reported cases of contact dermatitis to homemade slime in the literature; this serves to highlight the importance of a thorough exposure history in the evaluation of hand dermatitis.
