Article Alpha-lipoic acid may ameliorate testicular damage by targeting dox-induced altered antioxidant parameters, mitofusin-2 and apoptotic gene expression(Andrologia, 2021) Güzel, Elif Erdem; Kaya Tektemur, Nalan; Tektemur, AhmetIn the study, the ameliorating effects of alfa lipoic acid (ALA) against doxorubicin-induced testicular apoptosis, oxidative stress and disrupted mitochondrial fusion were investigated in male rats. Rats were divided into four groups as control, doxorubicin (DOX), DOX + ALA and ALA. A single dose of 15 mg/kg DOX was administered i.p to the DOX and DOX + ALA groups. 50 mg/kg ALA was given to the DOX + ALA and ALA groups by oral gavage every other day. After 28 days, rat testes and serum samples were collected and analysed. Administration of DOX alone caused a decrease in body and relative testicular weights, seminiferous tubule diameter and germinal epithelium thickness, Johnsen's score and serum testosterone levels. DOX treatment led to severe testicular damage such as tubular degeneration, and atrophic tubules. Also, the activities of superoxide dismutase and glutathione peroxidase were reduced, while the level of malondialdehyde was increased in the testis. The mRNA levels of apoptotic-related genes (CASP3, TP53, BAX, BCL2) and apoptotic index were increased, while mitofusin-2 decreased. DOX caused an increase in CASP3 and a decrease in mitofusin-2 immunoreactivities. Treatment with ALA markedly improved all of DOX-induced biochemical, histochemical and molecular alterations in rat testis. Consequently, ALA has a therapeutic role in ameliorating DOX-induced testicular damage in rats.Article The antioxidant and anti-apoptotic potential of Pleurotus eryngii extract and its chitosan-loaded nanoparticles against doxorubicin-induced testicular toxicity in male rats(Wiley, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Acay, Hilal; Yıldırım, AyferThis study was conducted to evaluate the protective role of Pleurotus eryngii extract (PE) and Pleurotus eryngii extract-loaded chitosan nanoparticles (PE-CSNP) against doxorubicin (DOX)-induced testicular toxicity in rats. Male rats were divided into six groups: control (DMSO/ethanol), PE (200 mg/kg PE), PE-CSNP (30 mg/kg PECSNP), DOX (10 mg/kg DOX, a single dose, i.p), DOX+PE (10 mg/kg DOX+200 mg/ kg PE) and DOX+PE-CSNP (10 mg/kg DOX+30 mg/kg PE-CSNP). PE and PE-CSNP were administered by oral gavage every other day for 21 days. DOX-treated rats showed histopathological impairment compared with the control group. There was an increase in the apoptotic index, caspase 3 (CASP3), BCL2-associated X apoptosis regulator (BAX), dynamin-related protein 1 (DRP1) expression and total oxidative status (TOS) in the DOX group, while mitofusin-2 (MFN2), total antioxidative status (TAS) and serum testosterone levels of the DOX group reduced when compared with the other groups. PE and PE-CSNP treatments provided significant protection against DOX-induced oxidative stress by reducing TOS levels and increasing TAS levels. CASP3, BAX, apoptotic index and DRP1-MFN2 expressions were restored by PE and PE-CSNP. However, the PE-CSNP showed higher antioxidant and anti-apoptotic efficacy compared with PE. Thus, our results provide evidence that CSNP and PE could synergistically have a potent antioxidant and anti-apoptotic therapy against DOX-induced testicular damage in male rats.Article Carbamazepine-induced renal toxicity may be associated with oxidative stress and apoptosis in male rat(Taylor & Francis Online, 2021) Erdem Güzel, Elif; Kaya Tektemur, Nalan; Tektemur, Ahmet; Etem Önalan, EbruCarbamazepine (CBZ) is the antiepileptic drug used in epilepsy and some psychiatric disorders. Besides its widely used, many adverse effects have been reported including hematotoxicity, hepatotoxicity, endocrine disorders, and testicular damages due to oxidative stress. However, the role of CBZ on renal toxicity is not fully known. In this study, we attempted to explain the connected mechanisms by focusing on the metabolism of CBZ-induced renal toxicity in rats. Twenty male Wistar-Albino rats were randomized into 2 groups (n = 10); control (1 mL/day distilled water, orally) and CBZ (25 mg/kg/day CBZ, orally) groups. After 60 days, TAS (total oxidant status) and TOS (total oxidant status) levels, histopathological features, some genes involved in apoptosis, 8-hydroxy-2-deoxyguanosine (8-OHdG) activity, and apoptotic cells were assessed of kidney tissue. The oxidative stress index (OSI) was measured from TAS and TOS levels. TOS levels and OSI significantly increased, while TAS levels decreased in the CBZ group relative to the control group. Histopathological observations, Caspase-3 (Casp3), Poly [ADP-ribose] polymerase-1 (PARP-1), 8-OHdG immunoreactivities, and apoptotic cells markedly raised in the CBZ group compared with the control group. Also, mRNA expression of Cytochrome c (Cytc) and CASP3 significantly increased in the CBZ group compared to the control group. In conclusion, long-term use of CBZ may promote renal damage in rats by inducing oxidative stress and apoptosis.Article Chronic effects of maternal tobacco-smoke exposure and/or α-lipoic acid treatment on reproductive parameters in female rat offspring(Taylor & Francis Online, 2020) Erdem Güzel, Elif; Nalan Kaya, Ahmet Tektemur, Nazife Ulker, Ahmet Yardimci, Ramazan Fazil Akkoc, Sinan Canpolat & Ibrahim EnverPrenatal tobacco-smoke exposure negatively affects the reproductive functions of female offspring and oxidative stress plays a major role at this point. Alpha-lipoic acid (ALA), well known as a biological antioxidant, has been used as a nutritional supplement and as a therapeutic agent in the treatment of certain complications during pregnancy. We aimed to investigate the effects of maternal tobacco-smoke exposure and/or ALA administration on puberty onset, sexual behavior, gonadotrophin levels, apoptosis-related genes, apoptotic cell numbers and oxidative stress markers in the adult female rat offspring. Sprague-Dawley rats were divided into four groups; control, tobacco smoke (TS), TS+ALA and ALA groups. Animals were exposed to TS and/or ALA for 8 weeks before pregnancy and throughout pregnancy. All treatments ended with birth and later newborn female rats were selected for each experimental group. The experiment ended at postnatal day 74-77. Maternal tobacco smoke advanced the onset of puberty in the female offspring of the TS group (p < 0.05). In all treatment groups; the mean number of anogenital investigations and lordosis quality scores showed a decline, serum luteinizing hormone levels significantly increased (p < 0.05) and several histopathological changes in ovaries were observed compared to the control group. In addition, an increase in apoptotic marker levels and apoptotic cell numbers was detected in the ovaries of all treatment groups. Decreased TAS and increased TOS levels were detected in all treatment groups compared to control. These findings suggested that maternal tobacco smoke and/or ALA administration may be leading to the impaired reproductive health of female offspring.

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. Yardimci A, Akkoc RF, Tektemur A, et al. Chronic Maternal Tobacco Smoke Exposure and/or Alpha-Lipoic Acid Treatment Causes Long-Term Deterioration of Testis and Sexual Behavior in Adult Male Rats.

N-acetyl cysteine (NAC) is used as the APAP antidote. Cyclosporin A (CsA) is suppressed mitochondrial damage by binding cyclophilin, a mitochondrial pore transport component. The study aimed to evaluate the effects of NAC, CsA, and NAC+CsA treatments on APAP-induced hepatotoxicity in mice. Mice were randomly divided into five groups (n = 6). 400 mg/kg/ip/single dose APAP, 1200 mg/kg/i.p/single dose NAC and 50 mg/kg/i.p/single dose CsA were performed. Light and electron microscopic alterations were investigated in liver samples. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and liver glutathione (GSH) were analyzed. 3-nitrotyrosine and cytochrome c immunoreactivities were evaluated in liver tissue. Here, we found that APAP leads to histopathological and ultrastructural changes in mice liver. Also, APAP increased cytochrome c and 3-nitrotyrosine immunopositive staining. Besides, a significant decrease in liver GSH and an increase in serum AST and ALT levels were detected in the APAP group. Interestingly, NAC+CsA treatment improved histological alterations, cytochrome c, and 3-nitrotyrosine immunoreactivities and liver GSH, serum AST/ALT levels caused by APAP. We suggest that the combination of NAC and CsA reduces acetaminophen-induced hepatotoxicity in mice.Article Effect of Auricular Acupressure in Management of Constipation in Palliative Care Patients(Sage Journals Home, 2023) Bıçak Ayık, Derya; Can, GülbeyazObjectives: This experimental randomized-controlled study was performed to define the efficacy of auricular acupressure (AA) in the management of constipation developing in palliative care patients. Methods: According to the pre-prepared randomization list, 44 patients were included in the experimental group and 46 patients were included in the control group. Routine clinical treatment and care implementation were maintained in the patients in both groups. AA was performed for 4 weeks in patients in the experimental group. During the study, to determine the complaints of the patients regarding constipation, the information in the daily patient chart was examined at least 5 times by interviewing with the patient/patient's relative in the clinic and/or via phone call, and the results were recorded in the patient chart and data collection forms. The independent variable of the study is AA application, and the dependent variables are constipation and quality of life. Results: It was determined that there was no statistically significant difference between the daily defecation frequency of the 2 groups during the first 11 days. However, after the 12th day, the daily stool frequency of the experimental group was higher compared to the control group and this difference obtained between the 2 groups was statistically significantly different. AA was effective in decreasing laxative use. Conclusion: This intervention increased stool frequency, reduced physical and psychosocial symptoms, anxieties, and improved stool satisfaction and it was an effective approach to improving the quality of life. It is recommended that the daily use of AA should be evaluated. The healthcare providers including nurses, patients, and patient relatives should be trained regarding AA.Article 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 ErkuşBackground: 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.Article Effect of Foot Massages on Postpartum Comfort and Pain Level of Mothers after Vaginal Delivery: A Randomized Trial(Holistic Nursing Practice, 2021) İçke, Sibel; Genç, RabiaThis study conducted on 66 mothers aimed to investigate the effect of foot massages postpartum using an introductory information form, the Postpartum Comfort Scale, the visual analog scale, and a drug follow-up card. It was concluded that foot massages positively improved comfort, reduced pain levels, and reduced unnecessary medications.Article The Effect of Skin-to-Skin Contact on Placental Separation Time and Initiation of Breastfeeding(Breastfeeding Medicine, 2023) Gündüz, Ülkin; Öztürk, SibelBackground: The first hour and minutes immediately after birth are quite important for both the mother and the newborn. Ensuring skin-to-skin contact (SSC) during this period has a positive effect on the mother both psychologically and physiologically, and it is also important in starting breastfeeding. Objective: The study was conducted to examine the effect of SSC on placental separation time and initiation of breastfeeding. Materials and Methods: This is a randomized controlled study. The sample of the study consists of a total of 84 women with primiparous birth and vaginal delivery, including 42 experimental and 42 controls. Data were collected using a personal information form, a chronometer, and the LATCH scale. The placental separation time for those in the experimental and control groups was determined by using a chronometer. Initiation and assessment of breastfeeding were evaluated at the first and 24th hours of birth using the LATCH scale. Results: The signs of placental separation occurred earlier in the experimental group than in the control group. The mean placental separation time was found to be 7.05 ± 4.37 minutes in the experimental group and 13.41 ± 5.24 minutes in the control group. A statistically significant difference was found between the groups in terms of placental separation time (p = 0.0001). Conclusion: This study concludes that SSC in the third stage of labor ensures earlier separation of the placenta and is effective in initiating breastfeeding.Article Evaluation of contraceptive intentions among pregnant women in the third trimester: A cross-sectional study(Wolters Kluwer, 2024) Yeşil, Yeşim; Dönmez, AyşegülThis study aims to determine contraceptive intentions of pregnant women in the third trimester. This cross-sectional study was conducted at a training and research hospital in Mardin province between March 2023 and May 2023. In total, 253 pregnant women who had the ability to communicate in Turkish and agreed to participate were included in the study. Data were collected through face-to-face interviews using a survey and the Contraceptive Intent Questionnaire (CIQ). The average age of the participants was 28.87 ± 5.35 with 30.8% of them holding a secondary school degree. It was found that there was a statistically significant difference in terms of CIQ score between categories of the following descriptive variables: education level, husband's/partner's education level, fertility plan, receiving family planning counseling during pregnancy, and paying for the contraceptive methods used (P = .046, P = .013, P < .001, P = .008, and P < .001 respectively). It was determined that pregnant women who had not received family planning counseling during pregnancy and paid for the contraceptive method had higher contraception intention.Article 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, NalanDoxorubicin (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.Article The investigation of effect of alpha lipoic acid against damage on neonatal rat lung to maternal tobacco smoke exposure(ELSEVIER SCIENCE BV, 2018) Erdem Güzel, Elif; Kaya, Nalan; Ozan, Gonca; Tektemur, Ahmet; Dabak, Durrin Özlem; Ozan, İbrahim EnverThis study was carried out to determine the changes in the lungs of the rat pups exposed to tobacco smoke during pregnancy period and to investigate the protective effects of alpha lipoic acid, which is administered during pregnancy, on these changes. Spraque-Dawley female rats were divided into four groups: control, tobacco smoke (TS), tobacco smoke + alpha lipoic acid (TS + ALA) and alpha lipoic acid (ALA). The rats in control group were untreated. Rats were exposed to TS twice a day for one hour starting from eight weeks before mating and during pregnancy. 20 mg / kg of ALA was administered to rats. On 7th and 21st days 7 of the pups from each group were decapitated. Histological, morphometric, biochemical and quantitative real-time RT-PCR analyzes were performed. Histopathological and biochemical changes were observed in TS group. While a significant decrease was observed both in SP-A and VEGF immunoreactivities and mRNA levels, caspase-3 immunoreactivity and TUNEL positive cells were increased in TS group. It is suggested that prenatal TS exposure leads to morphological and histopathological changes on lung development by causing oxidative damage in lungs of neonatal rats and the maternal use of ALA can provide a limited protective effect on the neonatal lung development against this oxidative stress originating from TS. Although pregnant women are increasingly aware on health risks of smoking, environmental tobacco smoke exposure is still a widespread problem. For this reason, it is thought that this damage can be partially reduced by some antioxidant supplements in pregnancy.Article King Oyster Mushroom, Pleurotus eryngii (Agaricomycetes), Extract Can Attenuate Doxorubicin-Induced Lung Damage by Inhibiting Oxidative Stress in Rats(International Journal of Medicinal Mushrooms, 2023) Kaya Tektemur, Nalan; Tektemur, Ahmet; Güzel, Elif ErdemDoxorubicin (DOX), a broad spectrum chemotherapeutic, has toxic effects on healthy tissues. Mitochondrial processes and oxidative stress act in the DOX-induced toxicity, therefore antioxidant therapies are widely used. The study was aimed to evaluate the therapeutic potential of Pleurotus eryngii extract (PEE), an extract of a fungus with antioxidant properties, against DOX-induced lung damage. Rats were divided into Control, DOX, DOX + PEE, and PEE groups (n = 6). DOX was administered intraperitoneally in a single dose (10 mg/kg BW) and PE (200 mg/kg BW) was administered by oral gavage every other day for 21 days. Histopathological evaluations, immunohistochemical analyses, total oxidant status (TOS)/total antioxidant status (TAS) method, and quantitative real-time polymerase chain reaction (qRT-PCR) analysis were performed. DOX led to severe histopathological disruptions in rat lungs. Also, DOX remarkably increased the expression of dynamin 1 like (DRP1) and decreased the expression of mitofusin 1 (MFN1) and mitofusin 2 (MFN2) genes, which are related to mitochondrial dynamics. Moreover, DOX caused an increase in TOS/ TAS and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels. On the other hand, PEE treatment remarkably normalized the histopathological findings, mitochondrial dynamics-related gene expressions, markers of oxidative stress, and DNA damage. The present study signs out that PEE can ameliorate the DOX-mediated lung toxicity and the antioxidant mechanism associated with mitochondrial dynamics can have a role in this potent therapeutic effect.Article Parents' Needs and Their Perceived Obstacles With Team Members in Perinatal Palliative Care: A Qualitative Phenomenological Study(Journal of Hospice and Palliative Nursing, 2022) Yaşar, Beril Nisa; Terzioğlu, FusunAdvances in prenatal diagnosis have made medical, psychological, and ethical issues regarding the diagnosis of fetal anomalies a crucial topic of research. This study identified the needs of parents of unborn babies with fetal anomalies and their views regarding the services of interdisciplinary team members in charge of assisting them. The sample consisted of 30 parents and 40 team members from a women's health education and research hospital. Data were collected through face-to-face interviews and were qualitatively analyzed using the phenomenological method of interpretation. The results showed that parents' physical, psychological, social, and spiritual needs during pregnancy, childbirth, and postpartum were not fully met after their unborn babies were diagnosed with fetal anomalies. The results also showed that team members needed a structured program, legal regulations, and training to provide holistic care. © Lippincott Williams & Wilkins.Article Postpartum Breastfeeding Practices and Attitudes in Parents: A Randomized Study to Evaluate the Effects of Individual and Group Breastfeeding Education of Mothers and Fathers(Springer, 2023) Yeşil, Yeşim; Öztürk Can, HafizeBackground Antenatal breastfeeding training is defined as the provision of breastfeeding information during pregnancy, which can be given in various ways, such as individual training and group training. The inclusion of fathers in this educational approach is associated with the initiation of breastfeeding, exclusive breastfeeding and duration of breastfeeding. However, studies involving fathers are limited. This randomized controlled study aimed to compare the effects of individual and group training given to parents and those of normal hospital practices on mothers' breastfeeding self-efficacy and fathers' attitudes toward breastfeeding. Methods The study was conducted randomly in a training and research hospital between March 2014 and September 2014 and included 180 people. Of them, 90 were prospective mothers who were in the third trimester of their pregnancy and were living with their husbands and received service from the obstetrics outpatient clinic of the hospital. The expecting mothers and their husbands were randomly assigned to three groups: individual training, group training and control group. After randomization, prospective mothers and fathers in all groups received training. In the first week, sixth week, and fourth month after delivery, the mothers' breastfeeding self-efficacy and breastfeeding attitudes as well as the attitudes of the fathers' toward breastfeeding were evaluated. Results There were no differences between the groups in terms of variables such as age, education status, family type, breastfeeding education status, and mode of delivery. There were significant differences between the scores obtained from the Breastfeeding Self-Efficacy Scale and its subscales in all three groups during the postpartum period (p <0.05). The highest scale scores were obtained at the postpartum fourth month in the individual training and control groups and at the postpartum sixth week in the group training group. There were differences between the scores obtained by the mothers and fathers during the postpartum process from the Iowa Infant Feeding Attitude Scale (p<0.05). Conclusion The analysis of all the results indicates that breastfeeding education given to parents in the antenatal period increases their breastfeeding self-efficacy and provides them with a positive attitude toward breastfeeding. However, further research is needed to determine whether individual or group training contributes to the development of breastfeeding self-efficacy and attitudes.Article 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, GülcanBackground: 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.Article A retrospective descriptive study of NANDA-I nursing diagnoses used by midwives working in obstetrics and gynecologic service: An example from south-eastern Turkey(Wiley Online Library, 2023) Yeşil, Yeşim; Baran, LeylaPurpose: This study aims to identify NANDA-I nursing diagnoses that midwives working in obstetrics and gynecologic service use while managing the electronic nursing care process. Methods: This retrospective study was conducted in a descriptive way to evaluate electronic care plan records of 3025 patients staying in obstetrics and gynecologic service between April 1, 2020. and April 1, 2021. Diagnoses in the records of the electronic care process were digitalized by two faculty members. Then, NANDA-I nursing diagnoses used by midwives were identified. NANDA-I nursing diagnoses used by midwives were identified. Findings: It was determined that diagnoses in care plans documented from the system within the 1-year period fell into eight domains and 10 classes, and 5819 diagnoses were given in total. The most frequent diagnoses given in obstetrics and gynecologic service were "acute pain" and "risk for bleeding." Conclusion: Findings of this study revealed that nursing care records in obstetrics and gynecologic service did not have a large number of diagnoses and interventions. Implications for nursing practice: Care plans directly reflect the contribution of the care to the patient. Consequently, midwives being aware of and recording nursing diagnoses while giving care will ensure a standardized language and visibility in care. More coverage of midwifery-related diagnoses in the midwifery curriculum will make NANDA-I nursing diagnoses more visible in midwifery as well.Article The effect of frailty levels of older individuals on their mental well-being and depression levels(Wiley, 2024) Bıçak Ayık, Derya; Cengiz, Zeliha; Işık, KevserBackground: Frailty has become an important public health issue. This study was conducted to determine the effect of frailty levels of older individuals on their mental well-being and depression levels. Methods: This descriptive cross-sectional study was conducted with a total of 325 older individuals aged 60 years and over. A demographic questionnaire form, the FRAIL Frailty Scale, the Warwick-Edinburgh Mental Well-Being Scale, and the Geriatric Depression Scale-Short Form were used to collect data. Data were evaluated using the SPSS 25.0 package program. Number, percentage, mean, standard deviation, Chi-square, correlation, and multiple regression analyses were used. Results: The mean age of the older individuals was 69.56 ± 7.75 years, and the variables of age, education level, income status, the person they were living with, regular medication use, forgetting to take medication, urinary incontinence, hospitalisation, and accidents were found to affect both frailty and depression (P < 0.05). There was a positive correlation between frailty and depression (r: 0.460, P < 0.001) and a negative correlation between mental frailty and well-being (r: -0.391, P < 0.001). Socio-demographic variables, depression, and mental well-being had a 40% effect on frailty (P < 0.001). Conclusion: Depression status and mental well-being level are related to frailty, so negativity in one of them negatively affects the other. In line with these results, it is recommended to determine the level of depression and mental well-being of older individuals with high risk of frailty, and according to the results of the research, to provide care and support regarding the predictors affecting frailty.Article The therapeutic effect of hesperetin on doxorubicin-induced testicular toxicity: Potential roles of the mechanistic target of rapamycin kinase (mTOR) and dynamin-related protein 1 (DRP1)(Elsevier, 2022) Tektemur, Ahmet; Kaya Tektemur, Nalan; Erdem Güzel, ElifClinical utilization of doxorubicin (DOX), which is a commonly used chemotherapeutic, is restricted due to toxic effects on various tissues. Using hesperetin (HST), an antioxidant used in Chinese traditional medicine protects testis against DOX-induced toxicity although the molecular mechanisms are not well-known. The study was aimed to examine the possible role of the mechanistic target of rapamycin kinase (mTOR) and dynamin 1-like dynamin-related protein 1 (DRP1) in the therapeutic effects of HST on the DOX-induced testicular toxicity. Rats were divided into Control, DOX, DOX + HST, and HST groups (n = 7). Single-dose DOX (15 mg/kg) was administered intraperitoneally and HST (50 mg/kg) was administered by oral gavage every other day for 28 days. Total antioxidant status (TAS), histopathological evaluations, immunohistochemistry, and gene expression level detection analyses were performed. Histopathologically, DOX-induced testicular damage was ameliorated by HST treatment. DOX reduced testicular TAS levels and increased oxidative stress markers, 8-Hydroxy-deoxyguanosine (8-OHdG), and 4-Hydroxynonenal (4-HNE). Also, upregulated mTOR and DRP1 expressions with DOX exposure were decreased after HST treatment in the testis (p < 0.05). On the other hand, DOX-administration downregulated miR-150-5p and miR-181b-2-3p miRNAs, targeting mTOR and mRNA levels of beclin 1 (BECN1) and autophagy-related 5 (ATG5), autophagic markers. Furthermore, these levels were nearly similar to control testis samples in the DOX + HST group (p < 0.05). The study demonstrated that HST may have a therapeutic effect on DOX-induced testicular toxicity by removing reactive oxygen species (ROS) and by modulating the mTOR and DRP1 expressions, which have a critical role in regulating the balance of generation/elimination of ROS.
