[Seroprevalence and Risk Factors of Hepatitis B, C and D in Adults in Trabzon, Türkiye]. / Trabzon'da 20 Yas Üstü Eriskinlerde Hepatit B, Hepatit C ve Hepatit D Seroprevalansi ve Risk Faktörleri.

Viral hepatitis are infections that can cause liver damage, become chronic, lead to cirrhosis, hepatocellular carcinoma and ultimately result in death due to their ability to spread in the community through blood and infected body fluids. The aim of this study was to determine the seroprevalence of hepatitis B (HBV), hepatitis C (HCV), and hepatitis D (HDV) transmitted through blood among individuals living in Trabzon province and to examine the factors potentially associated with seroprevalence. This cross-sectional study was conducted in Trabzon province, located in the northeast of Türkiye, including a total of 10 districts, including the central district. Since seroprevalence was calculated for HBV, HCV, and HDV in the study, the sample size was separately calculated for each, and the calculated maximum sample size of 1116 was accepted as the minimum sample size for the study. The study was completed with 1502 participants. Serological tests for HBV included HBsAg, anti-HBs, and anti-HBc IgG; for HCV, anti-HCV; and for HDV, anti-HDV were analysed. Data were evaluated for HBV risk factors using univariate analyses with Chi-square test and for multiple analyses using enter model logistic regression analysis. The mean age of the participants was 45.7 ± 16.6 years, with 767 (51.1%) being female. The prevalence of HBV seropositivity, indicating vaccination, was 23.0%, while the seroprevalence of HBV among unvaccinated adults was 27.4%. HBsAg positivity was 5.1%, and isolated anti-HBc IgG positivity was 4.2%. The proportion of individuals with HBsAg in the gray zone was 0.5%, while the positivity rates for anti-HBs and anti-HBc IgG (indicating past infection) were 17.6%. The prevalence of anti-HCV was six per thousand, while anti-HDV was not detected in the analyses. HBsAg positivity and co-infection with HCV were found in one person, and among the nine individuals positive for anti-HCV, isolated anti-HBc IgG positivity was detected in three. Increasing age, presence of a person with jaundice in the family, presence of diabetes mellitus, alcohol use and cupping therapy were identified as risk factors for HBV in the logistic regression analysis. Risk factors for HCV in univariate analyses were being over 40 years old, presence of hepatic steatosis and receiving dialysis treatment. The results of the study indicate that despite being included in our vaccination schedule and the administration of vaccines to high-risk adults, HBV still requires intensive attention as a public health problem. HCV, lacking a vaccine has been evaluated as an infectious agent that needs to be taken into consideration due to its potential risks and requires the complete implementation of individual and social precautions.

Heavy Metal and Trace Element Levels in Hair Samples from Fishermen in Turkey: The Fish/Ermen Heavy Metal Study (FHMS).

Toxic chemicals from polluted seas can enter the human body through seafood consumption and cause health problems. The aim of this study was to evaluate the levels of selected heavy metals and trace elements among fishermen who frequently consumed seafood and controls who consumed seafood less frequently in four provinces on the shores of the Sea of Marmara, which is heavily polluted by industrial activities. Fourteen elements (antimony, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, selenium, strontium, vanadium, and zinc) were analyzed in hair samples using the inductively coupled plasma-mass spectrometer method. Levels of arsenic (0.147 ± 0.067 µg/g vs. 0.129 ± 0.070 µg/g, p = 0.025), chromium (0.327 ± 0.096 µg/g vs. 0.269 ± 0.116 µg/g, p < 0.01), nickel (0.469 ± 0.339 µg/g vs. 0.403 ± 0.368 µg/g, p = 0.015), strontium (1.987 ± 1.241 µg/g vs. 1.468 ± 1.190 µg/g, p < 0.01), and zinc (103.3 ± 43.1 µg/g vs. 92.7 ± 37.4 µg/g, p = 0.047) were higher in the fisherman group than in the control group. No difference was found between the groups in terms of other elements. The findings suggest that heavy metal-trace element contamination in the Sea of Marmara may increase the exposure levels of individuals to some chemicals through seafood consumption.

The effect of postoperative ventilation strategies on postoperative complications and outcomes in patients with esophageal atresia: Results from the Turkish Esophageal Atresia Registry.

OBJECTIVES: Postoperative ventilatory strategies in patients with esophageal atresia (EA) and tracheoesophageal fistula (TEF) may have an impact on early postoperative complications. Our national Esophageal Atresia Registry was evaluated to define a possible relationship between the type and duration of respiratory support on postoperative complications and outcome. STUDY DESIGN: Among the data registered by 31 centers between 2015 and 2021, patients with esophago-esophageal anastomosis (EEA)/tracheoesophageal fistula (TEF) were divided into two groups; invasive ventilatory support (IV) and noninvasive ventilatory support and/or oxygen support (NIV-OS). The demographic findings, gestational age, type of atresia, associated anomalies, and genetic malformations were evaluated. We compared the type of repair, gap length, chest tube insertion, follow-up times, tensioned anastomosis, postoperative complications, esophageal dilatations, respiratory problems requiring treatment after the operation, and mortality rates. RESULTS: Among 650 registered patients, 502 patients with EEA/TEF repair included the study. Four hundred and seventy of patients require IV and 32 of them had NIV-OS treatment. The IV group had lower mean birth weights and higher incidence of respiratory problems when compared to NIV-OS group. Also, NIV-OS group had significantly higher incidence of associated anomalies than IV groups. The rates of postoperative complications and mortality were not different between the IV and NIV-OS groups. CONCLUSION: We demonstrated that patients who required invasive ventilation had a higher incidence of low birth weight and respiratory morbidity. We found no relation between mode of postoperative ventilation and surgical complications. Randomized controlled trials and clinical guidelines are needed to define the best type of ventilation strategy in children with EA/TEF.

The prevalence of diabetes and associated risk factors among adult population in a Turkish population (Trabzon city).

OBJECTIVE: The objectives of this study were to determine the prevalence of diagnosed and undiagnosed diabetes mellitus (DM) and prediabetes, and to evaluate the associated risk factors in a sample of adult Turkish population. METHODS: A total of 4000 eligible study subjects, aged 20 years or older, chosen by multistage sampling on a field were considered. Of those 3721 subjects (2139 women and 1582 men) participated in the study. RESULTS: The prevalence of prediabetes and DM were found to be as 6.4% and 10.4% (3.6% being newly diagnosed by this study), respectively. In multivariate logistic regression analysis, advanced age (OR:26.7, p < 0.0005 in the group 70 years and over), marriage (OR:2.05, p = 0.047), housewives (OR:1.34, p = 0.003), family history of diabetes (OR:2.84, p < 0.0005), overweight (OR:1.61, p = 0.026), obesity (OR:2.25, p < 0.0005), hypertension (OR:1.42, p = 0.007) and dyslipidemia (OR:1.38, p = 0.028) were independent risk factors for being diabetic. CONCLUSIONS: DM is an important health problem in the adult population of Trabzon city. Newly diagnosed diabetic patients who were unaware of their status are at high risk. To control DM and associated risk factors, effective public health education and taking urgent steps are needed.

An Investigation of Changing Attitudes and Behaviors and Problematic Internet Use in Children Aged 8 to 17 Years During the COVID-19 Pandemic.

PURPOSE: To examine the effects of the COVID-19 pandemic on the lifestyle, habits, and behavioral differences in children, and their changing internet use habits. METHODS: The research was planned as a cross-sectional study involving 4892 children aged 8 to 17 years attending schools in the city center of Trabzon, Turkey. Children's daily living activities, social habits, mood and temperament changes, and internet use were investigated before and during the pandemic. In terms of problematic internet use, internet addiction rates were evaluated using the validated Turkish-language version of the Parent-Child Internet Addiction Scale (PCIAT-20). RESULTS: The children's mean age was 13 ± 2.45 years, and 17.1% (n = 837) exhibited problematic internet use features on the PCIAT-20. Problematic internet use was higher in boys and in children older than 13 years. The presence of COVID-19 infection among members of the household, quarantine measures, attending private schools, the mother's occupation, the time spent by the mother and father on their mobile phones, and high parental education levels were associated with a high level of internet addiction. Families also described significant changes in their children's temperament and character compared with the pre-pandemic period. CONCLUSION: The prevalence of problematic internet use increased during the COVID-19 pandemic compared with previous studies from Turkey. Children were also more introverted, irritable, and pessimistic during the pandemic.

Effects of Treatment Adherence on Quality of Life in Hypoparathyroid Patients.

OBJECTIVES: This study aimed to evaluate the current situation of hypoparathyroid patients and to investigate the relationship between treatment adherence and quality of life. STUDY DESIGN: Prospective, multicentre study. METHODS: Adult patients presenting with the diagnosis of hypoparathyroidism to 20 different endocrinology clinics were included. They were receiving conventional therapies for hypoparathyroidism, using calcium, active vitamin D, and magnesium. We collected data on demographic features, disease- and treatment-related information, and results of routine laboratory tests, treatment adherence, and presence of complications. Beck Depression Inventory, Beck Anxiety Inventory, and Short Form-36 quality of life assessments were administered. RESULTS: Among the 300 patients studied, 60.7% were adherent to their treatment, and 34.1% had complications. Anxiety and depression scores were significantly higher in non-adherent versus treatment-adherent patients (p<0.001 and p=0.001, respectively). Most of the domains of quality-of-life scores were also significantly lower in non-adherent patients. Both anxiety and depression scores showed significant, negative correlations with serum calcium and magnesium concentrations (r=-0.336, p<0.001 and r=-0.258, p<0.001, respectively). CONCLUSIONS: Nearly 40% of the patients were non-adherent to conventional treatment for hypoparathyroidism, and such patients had higher anxiety and depression scores and poorer quality of life scores. Conventional treatment might not be sufficient to meet the needs of patients with hypoparathyroidism. In addition to seeking new therapeutic options, factors influencing quality of life should also be investigated and strategies to improve treatment adherence should be developed.

Turkish version of Brief Ataxia Rating Scale.

AIM: Our aim was to perform the Turkish-language adaptation of a practical ataxia rating scale for children. METHODS: The Brief Ataxia Rating Scale was subjected to cultural adaptation following receipt of the requisite permissions. Thirty-six children aged 4-18 years followed-up with a diagnosis of ataxia were included in the study. Evaluation of each child was recorded on video. The video recordings were scored independently by nine observers (four physiotherapists, one pediatric neurologist, and four pediatricians). Intra-rater reliability was tested by the same video images being scored twice, at 15-day intervals, by a pediatric neurologist. Intraclass correlation coefficients were used for inter-rater and intra-rater reliability. The Scale for the Assessment and Rating of Ataxia was used for concurrent validity. RESULTS: Good to excellent reliability was determined among the nine observers in terms of total scores with the intraclass correlation coefficient among the nine observers (intraclass correlation coefficient = 0.926; 95% CI: 0.885-0.956). Intra-rater reliability analysis results exhibited strong reliability in terms of scores elicited at two-week intervals (intraclass correlation coefficient = 0.967; 95% CI: 0.890-0.987, r = 0.97, p < 0.001). At concurrent validity analysis, a strong relation was determined between total Scale of the Assessment and Rating of Ataxia score and total Brief Ataxia Rating Scale score (r = 0.942, p < 0.001). CONCLUSION: The Turkish-language adaptation of the Brief Ataxia Rating Scale is reliable and valid for application in children.Implications for RehabilitationThis study shows the reliability and validity of the Turkish language adaptation of brief ataxia rating scale in children.The scale being both practical and easily applicable to ataxic children will contribute to broadening its use in the pediatric age group in particular.

Heavy Metal Concentrations in Trachurus Mediterraneus and Merlangius Merlangus Captured from Marmara Sea, Turkey and Associated Health Risks.

Rapid industrialization and excessive human population growth may cause deterioration in marine water quality and biodiversity. Heavy metals are one of the most common pollutants in the seas and marine organisms, including demersal and pelagic fish, can accumulate them from the environment. Assessment of the ecological risk of heavy metals from fish has an important role in public health. In this study, some heavy metal (Pb, Cd, As, Cr, Hg, Cu, Zn, and Fe) concentrations were determined in the muscle tissues of two commonly consumed fish species, Trachurus mediterraneus (Mediterranean horse mackerel) and Merlangius merlangus (Whiting), which are the fifth (14,222 tons/year) and sixth (6814 tons/year) highest commercial catches of marine fish species in Turkey, respectively. Heavy metal concentrations of samples collected from four sites (Adalar, Izmit Bay, Yalova, and Tekirdag) in the Marmara Sea were determined using ICP-MS. Fish samples caught at Yalova station were found to have the highest heavy metal concentrations. According to the World Health Organization (WHO), in terms of the mean values, only As, and Cr were higher than permissible limits in T. mediterraneus, while Pb, Cd, As, and Cr were higher in M. merlangus. Arsenic concentrations were higher than maximum limits in both T. mediterraneus and M. merlangus. The estimated weekly intake (EWI) was calculated to assess the potential health impact. The EWI for arsenic, cadmium, lead, and mercury for some sites was above the provisional tolerable weekly intake.

Heavy Metals and Trace Elements in Whole-Blood Samples of the Fishermen in Turkey: The Fish/Ermen Heavy Metal Study (FHMS).

Selected heavy metal-trace element (Ag, As, Ba, Cd, Cu, Hg, Pb, Sb, Se, Sr, and V) levels were determined by the ICP-MS method in whole-blood samples of fishermen and control group who accommodate in four provinces of the Marmara Sea. Mercury (1.267 ± 1.061 µg/L to 0.796 ± 0.853 µg/L) and lead (17.8 ± 9.0 µg/L to 12.0 ± 6.83 µg/L) levels were higher in the fishermen group than that of control group (p < 0.001 for both). There was no difference between the fishermen group and the control group in terms of whole-blood levels of other elements. Total monthly fish consumption was 9340.4 gr in the fishermen group and 326.4 gr in the control group, and the difference between the groups was significant (p < 0.001). There was no difference between the groups in terms of having amalgam dental filling (p > 0.05). The results suggest that consuming high amounts of sea products caught from the Marmara Sea is a source for some heavy metals such as mercury and lead, which poses a public health risk. Unlike the control group, the positive correlation between arsenic, copper, and strontium levels and age in fishermen can also be evaluated as an indicator of chronic exposure.

Sociodemographic characteristics and clinical risk factors of Helicobacter pylori infection and antibiotic resistance in the Eastern Black Sea region of Turkey.

BACKGROUND/AIMS: The aim of this study was to assess the clinical and sociodemographic risk factors of Helicobacter pylori infection and antibiotic resistance in the eastern Black Sea region of Turkey. MATERIALS AND METHODS: In total, 344 patients with dyspeptic symptoms who completed an extended questionnaire were enrolled in the study. Diagnosis of H. pylori infection was made by rapid urease test, histopathological investigation, and culture. Susceptibility of H. pylori strains was assessed by agar dilution (amoxicillin, tetracycline, metronidazole, levofloxacin) and E-test (clarithromycin) methods. RESULTS: The H. pylori positivity rate was 40.4% (139/344). Logistic regression analysis indicated that age and the presence of duodenal ulcer were independent risk factors associated with H. pylori positivity (odds ratio (OR): 0.96, 95% CI: 0.93-0.99, p=0.013; OR: 5.42, 95% CI: 1.96-14.98, p=0.001, respectively). Of 104 H. pylori-positive cultures, 43 strains (41%) were susceptible to all antibiotics, whereas 61 (59%) were resistant to at least one antibiotic. H. pylori resistance rates were 34% for levofloxacin, 31.1% for metronidazole, 28.2% for clarithromycin, 2.9% for amoxicillin, and 1% for tetracycline. Logistic regression analysis indicated that previous use of clarithromycin was the only independent risk factor for H. pylori resistance (OR: 6.25, 95% CI: 1.59-24.52, p=0.009). CONCLUSION: An understanding of the risk factors for H. pylori positivity and antibiotic resistance in an extended anamnesis may affect treatment choice and facilitate H. pylori eradication. In regions where antibiotic resistance rates are elevated, performing antibiotic susceptibility tests may lead to effective eradication treatment.

Turkish validity and reliability of the patient satisfaction scale in physiotherapy for patients with musculoskeletal pain.

BACKGROUND: Patient satisfaction is a key point in evaluating the quality of physiotherapy services. OBJECIVE: The aim of this study was to determine the Turkish language validity and reliability of the Patient Satisfaction Scale in Physiotherapy (PSSP). METHODS: The study included 168 participants, aged 18-74 years, with musculoskeletal pain. The PSSP, which comprises 14 items in the four sub-dimensions of treatment, admission, logistics and general satisfaction, was applied to all participants. Structural validity was assessed using the principal components method with varimax rotation. Internal consistency and the intraclass correlation coefficient (ICC) were used for the reliability analysis. The Patient Satisfaction Scale for Physical Therapy Outpatient Clinics (PCCPTO) was used to assess concurrent validity. RESULTS: The participants comprised of 71% females and 29% males with a mean age of 41.9 ± 14.9 years. The sampling competency index was 0.874. The Turkish version of the scale was found to be perfectly reliable (Cronbach's alpha reliability coefficient = 0.922). Internal consistency ranged from 0.762 to 0.904 in the subscales. Factor analysis revealed that the 14-item scale had four factors explaining 75.59% of the total variance. Floor and ceiling effects were not determined. Concurrent validity analysis showed a strong correlation between the PSSP and PCCPTO (r= 0.78; p< 0.0005). CONCLUSION: The Turkish version of the PSSP is a valid, reliable and easily applicable measure.

One-lung ventilation duration-dependent stress response in thoracotomies and the effect of a low-volume, high-frequency differentiated ventilation strategy on this response.

BACKGROUND: This study aims to investigate the effect of ventilation of the non-ventilated lung in patients undergoing one-lung ventilation by a separate low-tidal-volume (1 mL/kg) ventilator at high frequency (30/min) on preventing the effect of one-lung ventilation-associated oxidative damage. METHODS: The study included 45 patients (24 males, 21 females; mean age 54.6±7.7 years; range, 18 to 65 years) with an American Society of Anesthesiologists risk group of 1 to 2 and scheduled for elective thoracotomy. Patients were randomly divided into three groups as those due for thoracotomy without one-lung ventilation (group 1, n=15), those due for thoracotomy with one-lung ventilation (group 2, n=15), and those due for thoracotomy in whom both lungs were ventilated (group 3, n=15). Blood specimens were collected for ischemia-modified albumin, malondialdehyde, and lactate measurements one minute before one-lung ventilation (t0), 30 minutes after one-lung ventilation (t1), 60 minutes after one-lung ventilation (t2), and at postoperative 24th hour (t3). For group 1, t0 was defined as the time at which the thorax was opened. RESULTS: A statistically significant increase in ischemia-modified albumin, malondialdehyde, and lactate levels occurred in group 2 as the duration of one-lung ventilation increased (p<0.01). Plasma ischemia-modified albumin and malondialdehyde levels in group 3 were statistically significantly lower at t1, t2, and t3 compared with group 2 (p<0.01). Plasma lactate levels were significantly lower in group 3 at t1 (p<0.05) and t3 compared with group 2 (p<0.01). CONCLUSION: Separate ventilation of the non-ventilated lung with low tidal volume and high frequency reduces the response to one-lung ventilation-associated oxidative stress in thoracic surgery.

A novel method for improving chest tube insertion skills among medical interns. Using biomaterial-covered mannequin.

OBJECTIVES: To develop a low-cost biomaterial-covered chest tube simulation model and assess its possible usefulness for developing the chest tube insertion skills among medical interns. Methods: This mannequin-based interventional study was performed in a University hospital setting. We included 63 physicians performing emergency medicine internship at the Faculty of Medicine, Karadeniz Technical University, Trabzon, Turkey, between January 2015 and March 2015. A dummy was prepared for training simulation using a display mannequin. Medical interns received instruction concerning pneumothorax and the chest tube procedure. A total of 63 medical interns participating in this interventional study were asked to insert a chest tube in a biomaterial-covered mannequin. A senior trainee scored their performance using a check list and the mean of the total scores was calculated (21 items; total score, 42). Results: The mean procedural score was 40.9 ± 1.3 of a possible 42. The maximum score of 42 was achieved by 39.7% of the medical interns, while another 33.3% achieved a score of 41. Of the participants, 85% succeeded in inserting the tube via an appropriate technique, achieving a score of 40 or more. Conclusion: Our results indicated that this model could be useful for effective training of medical interns for chest tube insertion, which is an important skill in emergency medicine. This biomaterial-covered model is inexpensive and its use can potentially be widened to improve training methods without significant financial demand.

Ginkgo Biloba improves bone formation during fracture healing: an experimental study in rats.

OBJECTIVES: Ginkgo biloba extract (EGb 761) is a plant extract obtained from the leaves of the G. biloba tree. The aim of this study was to assess the histological and radiological effects of G. biloba extract on fracture healing in an experimental fracture model using rat femurs. METHODS: Forty-eight female Sprague-Dawley rats (weight: 195-252 g; age: 20 weeks) were used in the study. The rats were randomly divided into six groups (n=8). A transverse fracture was made in the middle of the right femur of each rat and fixed with a Kirschner wire. The G. biloba groups received 60 mg/kg oral G. biloba extract once daily. No medication was given to the control groups. On days 7, 21 and 35, both sets of femurs were evaluated radiologically and histopathologically. RESULTS: Histological evaluation revealed that the G. biloba groups had significant differences at 21 and 35 days (p<0.05). The G. biloba group showed a significant difference in terms of bone formation on day 21 when compared to the control group (p<0.05). CONCLUSIONS: This study indicated that the use of G. biloba extract accelerated fracture healing. Both radiological and histological differences were detected, but the histological differences were more remarkable. Level of Evidence I, High Quality Randomized Trial.

Determination of Seroprevalence of Borrelia burgdorferi IgG in Adult Population Living in Trabzon.

BACKGROUND: Lyme borreliosis is a tick-borne, multi-systemic infectious disease that is thought to be wide spread in Turkey even though studies on its seroprevalence are limited. AIMS: To determine the seroprevalence of Lyme borreliosis in part of north-eastern Tur-key (in the city of Trabzon), and to identify possible relationships between seropositivity and various factors such as location, gender, age group, occupation, income, and educational level. STUDY DESIGN: Retrospective cross-sectional study. METHODS: A total of 884 blood samples collected from provincial and district health centers serving a population of about 800,000 were included in this study. ELISA was used to determine the anti-Borrelia IgG antibody levels in the samples. Samples that yielded positive results by ELISA were further subjected to western blot (WB). RESULTS: IgG antibodies were found in 128 samples (14.5%). Statistical analysis revealed significant differences between age groups and educational levels in terms of the incidence of seropositivity, whereas location, gender, occupational group and income level had no effect (p<0.001, p<0.001, p=0.948, p=0.645, p=0.131, p=0.080 respectively). CONCLUSIONS: The risk of contracting Lyme borreliosis in Trabzon is high, and necessary measures need to be taken to avoid the spread of disease.

Turkish Final Year Medical Students' Exposure to and Attitudes Concerning Drug Company Interactions: A Perspective from a Minimally Regulated Environment for Medical Students.

Interactions between drug companies and medical students may affect evidence-based medical practice and patient safety. The aim of this study was to assess drug company-medical student interactions in a medical faculty where limited specific national or institutional regulations apply between drug companies and medical students. The objectives of the study were to determine the exposure and attitudes of final year medical students in terms of drug company-medical student and physician interactions, to identify factors affecting those attitudes and to provide data for policymakers working on the regulation of interactions between drug companies and medical students. This anonymous questionnaire-based study of 154 medical final year medical students at the Karadeniz Technical University Medical Faculty, Trabzon, Turkey, in April and May 2015 attracted a response rate of 92.2% (n/N, 154/164). Exposure to interaction with a pharmaceutical representative was reported by 90.3% (139/154) of students, and 68.8% (106/154) reported experiencing such interaction alongside a resident. In addition, 83.7% (128/153) of students reported an interaction during internship. Furthermore, 69.9% (107/153) of students agreed that interactions influence physicians' prescription preferences, while 33.1% (51/154) thought that a medical student should never accept a gift from a drug company and 24.7% (38/154) agreed with the proposition that "drug companies should not hold activities in medical faculties". Students with rational prescription training expressed greater agreement with the statement "I am skeptical concerning the information provided by drug companies during interactions" than those who had not received such training, and this finding was supported by logistic regression [O.R.(C.I), p -3.7(1.2-11.5), p = 0.022]. Acceptance of advertisement brochures was found to significantly reduce the level of agreement with the proposition that "A physician should not accept any gift from a drug company." (0.3[0.1-0.9], p = 0.030). In summary, exposure to drug companies was widespread among our final year medical students who, like students in both Western and non-Western societies, hold permissive attitudes concerning accepting gifts, and drug advertising brochures may relax those permissive attitudes still further. Rational prescription training was useful in generating rational attitudes. Policies concerning drug company-medical student relationships should be developed in Turkey as well as internationally.

The Effect of Empathy Training on the Empathic Skills of Nurses.

BACKGROUND: The profound impact of empathy training on quality nursing care has been recognized. Studies have shown that there has been little improvement in nurses' communication skills, and that they should work to enhance this area. Relevant training will lead to an improvement in nurses' empathic skills, which in turn, will enable them to understand their patients better, establish positive interpersonal relationships with them, and boost their professional satisfaction. OBJECTIVES: To reveal the effect of empathy training on the empathic skills of nurses. PATIENTS AND METHODS: This study was conducted as an experimental design. The research sample consisted of 48 nurses working at the pediatric clinics of Farabi hospital of Karadeniz Technical University in Turkey (N = 83). Two groups, an experimental group (group 1) and a control group (group 2) were determined after questionnaires were supplied to all nurses in the study sample. At first, it was intended to select these groups using a random method. However, since this may have meant that the experimental and control groups were formed from nurses working in the same service, the two groups were selected from different services to avoid possible interaction between them. The nurses in the Group 1 were provided with empathy training through group and creative drama techniques. Pre-tests and post-tests were conducted on both groups. Data was collected via a questionnaire designed around the topic "empathic skill scale-ESS", developed by Dokmen. The Kolmogorov Smirnov test was employed to assess whether the measurable data was suitable for normal distribution. Data was presented as numbers and percentage distributions, as mean ± standard deviation and Chi-square, and as student t tests and paired t tests. The level of significance was accepted as P < 0.05. RESULTS: The nurses in the experimental group had a mean score of 146.7 ± 38.8 and 169.5 ± 22.1 in the ESS pre-test and post-test, respectively. Although the nurses in the control group had a pre-test mean score of 133.7 ± 37.1, which increased to 135.1 ± 51.7 after the training, no statistically significant difference was found (P = 0.886). A comparison of the groups indicated that they scored similarly in the pre-test. However, the experimental group scored significantly higher than the control group in the post-test (P = 0.270 and P = 0.015, respectively). CONCLUSIONS: In the light of these findings, it is recommended that communication skills should be widely included in in-service training programs; similar studies should be conducted on broader control groups formed through randomization; and a comparison should be made between the findings.
