Background: Tobacco use during pregnancy is known to have several negative effects on the offspring's reproductive health in the long term. The use of alpha-lipoic acid (ALA) as a dietary supplement during pregnancy has increased greatly in recent years and has been known to have positive effects on various pregnancy outcomes including miscarriage, diabetic embryopathy, preterm delivery, and congenital malformations. Aim: To evaluate the effects of tobacco smoke exposure (TSE) on sexual behavior, reproductive parameters, and testicles in adult male rats and to reveal the possible role of ALA administration on these parameters. Methods: Pregnant rats (n = 7 per group) were treated with tobacco smoke (TS), ALA (20 mg/kg), and TS + ALA for a total of 11 weeks. The following parameters were compared with 8 control rats: puberty parameters, sexual behavior; levels of serum gonadotropins and testosterone, total antioxidant status, and total oxidant status; the expression of the apoptotic protease-activating factor-1 and caspase 9 mRNA levels in the testis; and assessment of immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick end labeling assay of testis. Main Outcome Measure: Sexual behavior, changes in puberty parameters, and hormonal and genetic alterations were the outcomes analyzed in this study. Results: Maternal TSE caused a significant decrease in the number of intromissions compared to the control group. Similarly, ALA decreased erectile function in sexual behavior by decreasing the number of intromissions and intromission ratio in the ALA group compared to the control group. In addition, TSE and ALA treatment caused an impairment of some consummatory sexual behaviors. Also, in parallel with this inhibitory effect, the age of pubertal onset was significantly delayed in the TS + ALA group compared to other groups. Also, histopathological changes in testicular tissue, oxidative stress markers, apoptotic index, and mRNA levels of apoptosis-related genes increased in all treatment groups. Clinical Implications: The use of ALA and/or tobacco products during pregnancy may adversely affect the reproductive health of male newborns in the long term. Strengths & Limitations: To the best of our knowledge, this study is the first to show the effects of maternal ALA treatment and/or TSE on the sexual behavior and reproductive parameters in male rats; however, the study is based on an animal model, and the present findings partially reflect the characteristics of human sexual behavior. Conclusion: Maternal TSE and/or ALA treatment may impair sexual behavior in adulthood in male rats because of testicular damage caused by oxidative stress during gonadal development.

The effect of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students, descriptive cross-sectional research study
(Nurse Education Today, 2021) Yaşar, Beril Nisa; Kaya, Yunus; Arslan, Sevda; Erbaş, Atiye; Küçükkelepçe, Gürhan Erkuş
Background: Factors affecting intercultural sensitivity and care are becoming an increasingly important issue due to ethnic diversity. Nurses play a crucial role in care and therefore should keep up with this trend and improve their intercultural sensitivity. Objective and design: This descriptive cross-sectional study investigated the effects of ethnocentrism and moral sensitivity on intercultural sensitivity in nursing students. Methods and participants: Data were collected using a demographic characteristics questionnaire and the Intercultural Sensitivity Scale, Generalized Ethnocentrism Scale, and Moral Sensitivity Scale. The sample consisted of 1343 nursing students. The Pearson correlation coefficient was used to determine correlations between scale scores. Multiple linear regression was used to determine the effects of ethnocentrism, moral sensitivity, and demographic characteristics on intercultural sensitivity. Results: Intercultural sensitivity was found to be negatively correlated with ethnocentrism and positively correlated with moral sensitivity. Ethnocentrism predicted intercultural sensitivity more than moral sensitivity. Ethnocentrism and moral sensitivity explained 16.8% of the total variance of intercultural sensitivity. However, ethnocentrism affected intercultural sensitivity more than moral sensitivity did (beta = −0.406). Conclusion: Nursing education should adopt strategies to reduce ethnocentrism by helping students develop cultural competence and intercultural sensitivity. Such education can equip nurses to provide higher quality care to patients of different cultural backgrounds.

Hesperetin may alleviate the development of doxorubicin-induced pulmonary toxicity by decreasing oxidative stress and apoptosis in male rats
(Elsevier, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan
Doxorubicin (DOX) is one of the most widely used chemotherapeutic agents. However, it causes pulmonary toxicity which decreases its clinical use in human cancer therapy. The present study was undertaken to obtain an insight into the potential protective effect of hesperetin (HES) against doxorubicin-induced pulmonary toxicity in rats. The animals were divided into 4 groups with 7 rats per group. The experimental treatments were as follows: Control, DOX, DOX + HES, and HES groups. DOX was administered at the dosage of 15 mg/kg i.p for a single dose. HES was administered at the dosage of 50 mg/kg by oral gavage every other day. After 28 days, biochemical parameters, oxidative stress status, histopathological changes, apoptosis-related genes and apoptotic index (AI) were examined of lung tissue. Histopathological changes, Poly [ADP-ribose] polymerase 1 (PARP-1), Caspase-3 (Casp3), Cytochrome c (Cytc), apoptosis-related genes, and AI significantly increased in the DOX group relative to the control group. Malondialdehyde (MDA) significantly increased, while superoxide dismutase (SOD) and glutathione peroxidase (GPx) decreased in the DOX group relative to the control group. However, histopathological findings, MDA, AI, and PAPR1, Casp3 protein expression, mRNA expression of Cytc significantly decreased, while SOD, GPx increased in the DOX + HES group relative to the DOX group. These results attested HES might be a potential agent for the treatment of DOX-induced pulmonary toxicity.

The relationship between unemployment anxiety, job satisfaction and migration attitude among the next generation of Turkish nurses: A cross-sectional study
(Elsevier, 2023) Öncü, Emine; Köksoy Vayısoğlu, Sümbüle; Karadağ, Gülendam; Şahin Orak, Nuray; Selçuk Tosun, Alime; Doğan Yüksekol, Özlem; Çatıker, Aslıhan; Çiftçioğlu Yalçın, Gülcan
Background: The global nursing shortage is complex and multifaceted. Despite the policy of increasing the number of nurses, concerns about the sustainability of the nursing workforce in Turkey continue. Aim: To evaluate the relationship between unemployment anxiety, job satisfaction, and migration attitudes among Turkish nursing candidates. Methods: A cross-sectional study was conducted with 1100 nursing candidates between April and June 2022. The data gathered from the "Personal Form, Job Satisfaction, and Brain Drain Attitudes Scale" were analyzed using logistic regression and decision tree analysis. Results: Of the participants, 67.1% were female, and the mean age was 22.6 ± 1.7 years. Being male (OR = 1.317, 95% Cl 0.994-1.743) having a low income (OR = 1.754, 95% Cl 1.334-2.306), feeling insecure about the future (OR = 2.340, 95% Cl 1.312-4.175), expecting a lower wage than desired (OR = 2.015, 95% Cl 1.132-3.586), and employment precariousness (OR = 1.786, 95% Cl 1.355-2.353) increase the possibility of experiencing high unemployment anxiety. On the other hand, family support for living abroad (OR = 0.579, 95% CI 0.408-0.821) and job satisfaction (OR = 0.799, 95% CI 0.692-0.921) decrease unemployment anxiety (p < 0.05). According to the results of the decision tree analysis, the host country's pull factors are the best predictors of the nursing candidates' intention to work abroad as nurses (p < 0.05). Conclusion: The increasing prevalence of unemployment anxiety and migration tendencies among nursing candidates requires the evaluation of policies aimed at increasing the number of nursing graduates in Turkey.
