Objective: This study investigated the relationship of anthropometric and metabolic risk factors with seminal and sex steroidal hormone parameters in a screened population of healthy males. Methods: The participants were healthy young men without chronic or congenital diseases. The body composition parameters that we investigated were measured weight, height, and waist circumference (WC), as well as bioelectrical impedance analysis. Semen samples were analyzed for semen volume, sperm concentration, sperm motility and morphology, seminal pH, and liquefaction time. Biochemistry analysis, including glucose and lipid metabolism parameters, was conducted on fasting blood samples. Testicular volume was calculated separately for each testis using ultrasonography. Results: Body mass index exhibited an inverse association with total sperm count. WC showed negative correlations with numerous seminal parameters, including sperm concentration, total sperm count, sperm morphology, and follicle-stimulating hormone levels. The basal metabolic rate was associated with seminal pH, liquefaction time, and sperm motility. WC, fat mass percentage, and triglyceride levels exhibited negative correlations with sex hormone binding globulin. The measures of glucose metabolism were associated with a greater number of seminal parameters than the measures of cholesterol metabolism. C-reactive protein levels were inversely associated with sperm concentration and total sperm count. Conclusion: Anthropometric and metabolic risk factors were found to predict semen quality and alterations in sex steroidal hormone levels.

Objective: Although various methods have been identified for the appropriate tibial nail length, there are disadvantages such as extra time, radiation exposure, and additional cost. We aimed to predict the ideal length of the nail according to the patient's height and shoe size in the preoperative period to eliminate these disadvantages. Materials and Methods: Between January 2018 and August 2023, the height and shoe size data of 71 patients who were diagnosed with tibial shaft fracture and had tibia intramedullary nail fixation were determined. A linear regression model was applied to the normally distributed data. The correlation coefficient between the variables was evaluated according to the Pearson correlation coefficient. Results: While 1 1 -centimeter (cm) increase in patient height causes an increase of 3.2 millimeters (mm) in nail length, it was found that it alone contributed by 89% to predicting the ideal nail length (p<0.001). An increase of 1 unit in shoe size (EU) causes an increase of 9 mm in nail length; its contribution to predicting the ideal nail length alone is 84% (p<0.001). In the evaluation of the patient's height and shoe size together, it was observed that they jointly contributed 91% to the accurate estimation of the nail length (p<0.001). Conclusion: It may be risky to determine the tibial nail length only by shoe size or the patient's height. However, the correlation between them is strong. Therefore, by estimating nail lengths before the operation, the ideal nail length can be found by making fewer fluoroscopy checks during the operation.

Objective: Coronavirus disease-2019 has resulted in changes in healthcare and management services. One of these changes is
related to in patient presentation to emergency departments (ED). This study aimed to investigate the rate of recurrent presentations
to an ED during the pandemic period compared to the pre-pandemic period.
Materials and Methods: Patients that presented to the ED of a tertiary hospital again within 72 hours of their first visit were
screened from the hospital information management system for the pre pandemic (June 1-November 30, 2019) and pandemic (June
1-November 30, 2020) periods. So, hospitalization rates were compared between the two periods.
Results: In the pre-pandemic period, the number of ED registrations was 67,414, of which 3,463 belonged to recurrent presentations,
while in the pandemic period, these numbers were determined as 43,636 and 2,238, respectively. The rate of admission to any
hospital ward (n=521, 16.4%) or the intensive care unit (n=56, 1.8%) nearly doubled during the pandemic. Six of these patients died
in the ED in the pandemic period, while no death was observed in the pre-pandemic period.
Conclusion: Although there was a decrease in the number of both hospital and ED presentations during the pandemic, an increase
was observed in the number of patients with recurrent presentations to the ED. As a result of this patient group postponing visits
to the hospital for their acute problems due to the fear of being infected, their need for hospitalization and intensive care follow-up
increased.; Amaç: Koronavirüs hastalığı-2019 (COVID-19) sağlık bakım ve yönetim hizmetlerinde değişikliklere neden oldu. Bu değişikliklerden
biri de acil servis hasta başvurularında yaşandı. Bu çalışmada pandemi döneminde acil servislerde tekrarlayan başvuru oranlarının
araştırılması amaçlanmıştır.
Gereç ve Yöntemler: Pandemi öncesi dönem (1 Haziran-30 Kasım 2019) ile pandemi döneminde (1 Haziran -30 Kasım 2020) 3.
basamak bir hastanenin acil servisine ilk başvuru sonrası 72 saat içerisinde tekrar başvuruda bulunan hastalar hastane bilgi
yönetimi sistemi üzerinden taranmıştır. Hastane ve acil servis başvuru sayıları, demografik özellikleri ve hastaneye yatış oranları
her iki dönem açısından karşılaştırılmıştır.
Bulgular: Pandemi öncesi dönemde acil servis kayıt sayısı 67.414 olup bu hastalar içerisinde 3.463’ü tekrarlayan başvuruyken,
pandemi döneminde kayıt sayısı 43.636 olup bunların 2.238’i tekrarlayan başvuruda bulunmuştur. Dönemler arasında istatistiksel
olarak yaş ve cinsiyet açısından farklılık tespit edilmemiştir (p=0,143). Ancak tekrar başvuruda bulunan hastalar arasında yatarak
takip ve tedavi edilmesi gereken hasta grubunun yaşı pandemi döneminde daha yüksekti. Pandemi döneminde herhangi bir kliniğe
(n=521, %16,4) veya yoğun bakım ünitesine yatış (n=56, %1,8) oranlarında yaklaşık iki kat artış oldu. Bu hastalardan 6’sı pandemi
döneminde acil serviste ölümle sonlanıma sahipken normal dönemde ölümle sonlanım görülmemiştir.
Sonuç: Pandemi döneminde hem genel hastane hem de acil servis başvuru sayılarında azalma olmasına rağmen acil servise
tekrarlayan başvuruda bulunan hasta sayısında artış olduğu tespit edildi. Bu hasta grubunun enfekte olma korkusu nedeniyle akut
gelişen problemlerini ertelemesi karşısında herhangi bir kliniğe yatış ve yoğun bakım ünitesinde takip edilme ihtiyaçlarının artığı
görüldü.

Interaction between neurogenic pulmonary edema and thoracic 3 DRG degeneration following spinal subarachnoid hemorrhage; first experimental study

Aim: Neurogenic pulmonary edema (NPE) following subarachnoid hemorrhage (SAH) is still one of the most catastrophic complications with its high morbidity and mortality rate. Systemic sympathetic hyperactivity has been considered in the pathogenesis, but it has not been clarified. In this study, the relationship between the degeneration of Th3 dorsal root ganglion (DRG) and developing NPE following spinal SAH was investigated.
Methods: The study was conducted on 23 rabbits. Five of them were used as the control group (n=5), and the remainder was divided into the SHAM group (n=5) and the study group (n=13). The correlation between degenerated neuronal densities of Th3 nerve axons and neurons in DRG and NPE scores were analyzed statistically Results: A correlation between the study and the SHAM group was found for neuronal degeneration Th3 nerve, its DRG, and high NPE scores. Massive NPE was detected in the study group along with neural degeneration of Th3 axons and ganglia.
Conclusion: The present study indicates that neurogenic pulmonary edema and pulmonary artery vasospasm can be prevented by reducing Th3 DRG degeneration.
