Correlation between Preoperative Anxiety and ABO Blood Types: Evidence from a Clinical Cross-Sectional Study

The overlooked problem among surgical patients: Preoperative anxiety at Ethiopian University Hospital

Introduction

Anxiety was repeatedly reported as the worst aspect of the perioperative time. The objective of this study was to assess the prevalence of preoperative anxiety among adult surgical patients at University of Gondar Comprehensive Specialized Hospital (UoGCSH), Northwest Ethiopia.

Methodology

A hospital-based cross-sectional study was conducted among surgical patients at the university hospital. After obtaining ethical approval, 407 surgical patients were approached during the preoperative period. Preoperative anxiety was assessed by State-Trait Anxiety Inventory. The association between variables was determined by using binary logistic regression analysis. Strength of association was described in adjusted odds ratio (AOR), and a p-value < 0.05 at 95% confidence interval was considered statistically significant.

Results

A total of 400 patients were included in this study with a 98.3% response rate. Preoperative anxiety was observed among 237 (59.3%) patients, and the median (IQR) STAI score was 50 (40-56.7); age, ≥ 60 years (AOR: 5.7, CI: 1.6-20.4, P: 0.007); emergency surgery (AOR: 2.5, CI: 1.3-4.7, P: 0.005); preoperative pain (AOR: 2.6, CI: 1.2-5.4, P: 0.005); and rural residency (AOR: 1.8, CI: 1.1-2.9, P: 0.031) were found significantly associated with preoperative anxiety.

Conclusion

The prevalence of preoperative anxiety among surgical patients was high. Older age (≥ 60 years), emergency surgery, preoperative pain, and rural residency were found significantly associated with preoperative anxiety. Assessment for preoperative anxiety should be a routine component of preoperative assessment of both elective and emergency surgical patients. Preoperative pain should be appropriately managed as it can help to reduce preoperative anxiety. Optimal anxiety reduction methods should be investigated and implemented in the hospital.

COVID-19: sleep research perspectives

Coronavirus disease of 2019 (COVID-19) pandemic originated from Wuhan in December 2019 and has been spread in whole China and the world. Worldwide outbreaks of COVID-19 triggered a large number of morbidities and mortalities beside its economic and social burdens, which are discussed a lot, in scientific literature and different types of media. As a sleep medicine specialist, we may wonder how we can be involved in this field. In this short theoretical essay, we will discuss about the known facts as well as the hypotheses, which associate the sleep medicine to COVID-19. The discussed points may provide a source of research ideas throughout the world for better understanding of novel coronavirus-19 that has devastating effects on humanity.

Treatment of experimentally induced benign prostatic hyperplasia with Tadalafil and castration in dogs

New methods are being developed for the treatment of benign prostatic hyperplasia (BPH) in dogs. The aim of the present study was to evaluate the effects of Tadalafil on the treatment of experimentally induced BPH in dogs. Twenty-five adult intact male dogs were randomly divided into five groups (n = 5): normal group; dogs induced with BPH and treated with Tadalafil (5 mg/day p.o.); dogs which received Tadalafil (5 mg/day p.o.); dogs induced with BPH and treated with castration; and dogs induced with BPH. For 4 sequential weeks, the hematologic and prostate-specific factors (dihydrotestosterone (DHT), serum prostate-specific antigen (PSA), serum prostatic acid phosphatase (PAP), and canine prostatic specific esterase (CPSE)) were measured. Significant differences were observed in the level of PSA, CPSE, and PAP concentration between the normal vs. BPH-Tadalafil, BPH-castrated, and BPH groups. Treating BPH-induced dogs with Tadalafil or castration significantly declined the serum PSA, CPSE, and PAP levels compared to those of the untreated BPH-induced group. The treatment of normal dogs with Tadalafil did not affect prostate-specific biomarkers in comparison with normal dogs. In conclusion, and according to the prostatic indices, it could be stated that Tadalafil, compared with castration, could be used for the treatment of BPH in dogs.
