Investigation of the anticancer effect of newly synthesized palladium conjugate Schiff base metal complexes on non-small cell lung cancer cell line and mouse embryonic fibroblast cell line.

Lung cancer remains one of the leading causes of death worldwide. Due to the side effects of chemotherapeutic agents on normal cells and the development of resistance by cancer cells, there is an urgent need for alternative new pharmacological agents. Palladium (Pd)-conjugated Schiff base (SB) compounds represent an alternative approach with promising potential applications in cancer treatment. This study aims to identify novel therapeutic agents on A549 cells through the synthesis and characterization of Schiff base conjugated-Palladium complexes (Pd-L1 and Pd-L2). Additionally, it seeks to elucidate the mechanism of action of these compounds on both the A549 and NIH/3T3 cell lines. In the present study, two new Pd-L1 and Pd-L2 were synthesized for the first time and characterized mainly by single crystal X-ray diffraction and 1H, 13C, 31P NMR techniques. The cytotoxic effect of the compounds was evaluated by MTT assay on A549 and NIH/3T3 cell lines for 24 and 48 h. Cisplatin was used as a positive control group. Based on the cytotoxicity results, the complexes were evaluated for their anticancer activities against A549 cell lines for 48 h through reactive oxygen species (ROS), cell cycle, apoptotic, and necrotic cell analyses. The most potent cytotoxic effects were determined for Pd-L1 (IC50: 23.33 µM), Pd-L2 (IC50: 3.19 µM), and cisplatin (IC50: 33.27 µM) on A549 cells (p < 0.05). The compounds exhibited a significant cytotoxic effect at lower concentrations on A549 cells compared to NIH/3T3 cells (p < 0.05). All compounds showed a significant increase in ROS levels in A549 cells compared to the control group (p < 0.05). While necrosis and apoptosis was observed in A549 cells treated with cisplatin, induction of apoptosis was effective in cell death for A549 cells treated with Pd-L1 and Pd-L2 (p < 0.05). Additionally, it was observed that the compounds inhibited cell proliferation in the G0/G1 and G2/M cell cycle phases (p < 0.05). All compounds induced cell cycle arrest and cell death in A549 cells by increasing ROS levels. The results obtained in the present study could advance the utilization of the compounds as anticancer agents.

The 2023 Türkiye-Syria earthquakes: analysis of pediatric victims with crush syndrome and acute kidney Injury.

BACKGROUND: On February 6th, 2023, two consecutive earthquakes struck southeastern Türkiye with magnitudes of 7.7 and 7.6, respectively. This study aimed to analyze the clinical and laboratory findings, as well as management of pediatric victims with Crush Syndrome (CS) and Acute Kidney Injury (AKI). METHODS: The study included pediatric earthquake victims who were presented to Mersin University Hospital. Clinical and laboratory characteristics of the patients were collected retrospectively. RESULTS: Among 649 patients, Crush injury (CI), CS and AKI was observed in 157, 59, and 17 patients, respectively. White blood cell count (12,870 [IQR: 9910-18700] vs. 10,545 [IQR: 8355-14057] /µL, P < 0.001), C-reactive protein (51.27 [IQR: 14.80-88.78] vs. 4.59 [1.04-18.25] mg/L, P < 0.001) and myoglobin levels (443.00 [IQR: 198.5-1759.35] vs. 17 [11.8-30.43] ng/ml) were higher in patients with CS, while their sodium (IQR: 134 [131-137] vs. 136 [134-138] mEq/L, P < 0.001) levels were lower compared to non-CS patients. An increase in myoglobin levels was identified as an independent risk factor for developing CS (OR = 1.017 [1.006-1.027]). Intravenous fluid replacement was administered to the patients with CS at a dose of 4000 cc/m2/day. Hypokalemia was observed in 51.9% of the CS patients on the third day. All patients with AKI showed improvement and no deaths were reported. CONCLUSIONS: Hyponatremia and increase in inflammation markers associated with CS may be observed. An increase in myoglobin levels was identified as a risk factor for CS. Hypokalemia may be seen as a complication of vigorous fluid therapy during hospitalization.

The prevalence and associated factors of fear of childbirth among Turkish pregnant women.

OBJECTIVE: This study was conducted to determine the prevalence of fear of childbirth and affecting factors in pregnant women in Turkey. MATERIALS AND METHODS: This was a cross-sectional study and included a total of 2025.    Pregnant Women Assessment, some variables related to previous and current perinatal processes and Wijma Delivery Expectancy/Experience Questionnaire (version A) were used for data collection. FINDINGS: In this sample, 42.4% of the women reported fear of childbirth. What the women were afraid of most was the development of unwanted conditions at childbirth, obscurity/uncertainty, and negative attitudes of health professionals. The factors causing fear of childbirth were the low education level, unemployment status, low financial status, stillbirth, unplanned pregnancy, indecisiveness about the type of delivery, not attending prenatal education programs, negative effects of other people, insufficient social support, confiding in the healthcare centre and health professional, negative, and indecisive birth perceptions, prior negative birth experiences and not feeling ready for childbirth (p < 0.001). CONCLUSIONS: The prevalence of fear of childbirth in this Turkish sample, especially in the multipara is higher than in Western countries. Causes of fear of childbirth can vary with countries and even with each region of a country.

When should a premature neonate (24-35 weeks) be discharged? five-year experience from a single-center neonatal intensive care unit in Türkiye.

Background/aim: The survival rate among preterm infants has improved, and hospital stays have been prolonged, consistent with positive developments in perinatal and neonatal care. The aim of this study was to provide evidence-based information for healthcare professionals concerning the ideal time for discharge by evaluating the reasons for prolonged hospital stays. Materials and methods: Six hundred eighty-one premature babies born at 24-35 weeks at the Mersin University Medical Faculty Hospital between January 2016 and May 2020 and admitted to the neonatal intensive care unit were included in the study following a retrospective file examination. Date of birth (gestational age) and discharge week (duration of hospital stay) calculated from the date of final discharge were recorded. Based on the literature, the ideal discharge time was determined to be 40 weeks according to postmenstrual age (week of birth + length of hospital stay). The primary variable was whether the infants were discharged before the ideal discharge week. The secondary variable was the effect of the presence of comorbidity on the length of hospital stay and ideal discharge time. Results: The mean hospital stay of preterm neonate born at 250-7-260-7, 270-7-280-7 and 290-7-300-7 weeks was significantly shorter in the absence of comorbidity than in the presence of comorbidity (p = 0.001, 0.004, and 0.008, respectively). More than half (53.5%) were discharged before the expected date of birth as gestational weeks increased, despite the prolonged length of stay in the presence of comorbidity. Conclusion: Health professionals can inform families that, in the absence of comorbidity, discharge is possible at an average of 36 weeks for 250-7-280-7-week gestational ages, and at an average of 34 weeks for 290-7-320-7-week gestational ages.

Platelet Indexes for Predicting Disease Severity and Prognosis in Elderly Patients with Coronavirus Disease-19.

BACKGROUND: This study aimed to investigate the usefulness of platelet indices in predicting prognosis in coronavirus disease-19 (COVID-19). METHODS: Patients aged ≥ 65 years who presented to the emergency department with a positive polymerase chain reaction test were retrospectively analyzed. RESULTS: Significant differences were found in the mean values of platelet (PLT) and plateletcrit (PCT) parameters in those with severe disease, those who died, and those who required intensive care unit (ICU) admission. Mean PLT and PCT values were higher in patients with severe COVID-19 (p-values < 0.001, for both), those requiring ICU admission (p = 0.016; p = 0.006; respectively), and those who died (p = 0.015; p = 0.005, respectively). PLT and PCT were found to be statistically significant in predicting death [PLT (area under the curve (AUC): 0.598; p = 0.0145) and PCT (AUC: 0.617; p = 0.0034)], severity [PLT (AUC: 0.653; p = 0.0002) and PCT (AUC: 0.654; p = 0.0002)], and ICU admission [PLT (AUC: 0.598; p = 0.0235) and PCT (AUC: 0.605; p = 0.0148)]. CONCLUSIONS: PLT and PCT values were significantly higher in patients with high disease severity, those requiring ICU admission, and those who died. Furthermore, they were statistically significant in predicting disease severity, ICU admission, and death.

Evaluation of platelet indices in children with renal scarring based on diagnostic accuracy criteria and Cohen's kappa.

BACKGROUND: Renal scarring is a significant complication in recurrent urinary tract infections (UTIs) in children that can lead to hypertension and end-stage renal disease. The present study evaluates whether platelet indices may be predictive of renal scarring. METHODS: Sixty-nine patients aged 1-18 years with recurrent UTIs, whose medical records were reviewed to collect data on the presence of upper/lower UTIs and the results of scintigraphic investigations with 99m-technetium dimercaptosuccinic acid, were included in the study. The platelet, platelet indices (mean platelet volume [MPV]), platelet distribution width, plateletcrit, and C-reactive protein (CRP) values of the patients during UTI episodes were reviewed retrospectively. RESULTS: Mean platelet volume and CRP values were higher in the renal scarring group than in the non-renal scarring group (P < 0.001 and P = 0.003, respectively). Increases in MPV and CRP values were independent risk factors for renal scarring (OR = 5.781 [1.431-23.347] and OR = 1.922 [1.77-3.141], respectively). The sensitivity, specificity, positive and negative predictive values, and diagnostic odds ratio values of MPV at a cut-off of >8.2 fL for renal scarring discrimination were 62.5%, 88.89%, 75.00%, 81.63%, and 13.33 [1.35-3.83], respectively. The sensitivity, specificity, positive and negative predictive values, and diagnostic odds ratio values of CRP at a cut-off of 1.97 mg/L for renal scarring were 58.33%, 91.11%, 77.78%, 80.39%, and 14.35 [1.36-3.97], respectively. CONCLUSION: Both MPV and CRP can be used as predictive markers for renal scarring. While MPV had higher sensitivity, CRP had a higher specificity and diagnostic odds ratio in predicting renal scarring.

Examination of individuals' depression, anxiety, and stress levels during the COVID-19 pandemic in Turkey.

PURPOSE: This research was conducted to determine the depression, anxiety, and stress levels of individuals during the COVID-19 epidemic. In addition, the compatibility of the Depression-Anxiety-Stress Scale (DASS-21) scale results with the participants' feeling depressed, anxious, and stressed were examined. DESIGN AND METHODS: The sample of the study consisted of 870 individuals over the age of 18 between May-August 2021. The data of the study were collected online, using the personal information form and DASS-21. RESULTS: In our study, it was observed that 22.3 % of the participants were severely depressed, 19.0 % were highly anxious and 14.3 % were highly stressed. In addition, a relationship was determined between many sociodemographic variables and depression, anxiety, and stress levels. It was found that individuals who were not vaccinated, did not receive health care, and were not satisfied with health care were more depressed, anxious, and stressed. The agreement between all DASS-21 sub-dimensions and participants' feeling is poor in terms of Cohen's kappa. The agreement is poor in the anxiety sub dimension, but moderate in the other sub-dimensions in terms of Gwet's AC1. PRACTICE IMPLICATIONS: It is recommended that nurses develop new care and evaluation strategies for the psychosocial field in order to protect and maintain the health of individuals during the COVID-19 pandemic process, as well as more practices promoting the COVID-19 vaccine in our country.

The prognostic value of immature granulocyte in patients with acute pancreatitis.

BACKGROUND: Acute pancreatitis is the inflammation of the pancreas. It can range from mild forms to life-threatening severe cases. There is not yet a marker that can detect severe cases in the early period. Early diagnosis and treatment of this disease has critical importance for prognosis. In this study, we aimed to investigate the percentage of immature granulocyte (IG %) in patients with acute pancreatitis in order to predict the severity of the disease and in-hospital mortality. METHOD: This study was carried out retrospectively in academic emergency department (ED), faculty of medicine between 01.01.2017 and 30.06.2019. The patients were divided into three groups as mild, moderate and severe. In addition, the patients were divided into two groups: those discharged from the hospital and those who died in the hospital. IG % and other laboratory parameters of the patients were recorded in the study form. The primary outcome for this study is the value of IG% in predicting severity in AP patients. A receiver operating characteristic (ROC) curve analysis was performed. RESULTS: A total of 218 patients (107 male) were included in the study. The mean age of the patients was 56.9 ± 18.3 years. It was found that IG% levels were higher in patients with severe pancreatitis (p = .018). In the ROC analysis that was done to determine the severity of the disease, the cut-off value of IG% was found as >1.1. As such case, specificity was %38.89, sensitivity was 95.00%, positive predictive value (PPV) was 41.18% and negative predictive value (NPV) was found as 94.53% (Area Under Curve (AUC) = 0.698). In ROC analysis that was performed to determine in-hospital mortality, the cut-off value of IG level was found as >1.8, sensitivity was 50.00%, specificity was 97.12%, PPV was 45.45% and NPV was found as 97.58% (AUC = 0.708). CONCLUSiONS: This study shows that higher IG% levels may correlate with higher disease severity and in-hospital mortality in patients with acute pancreatitis.

Vitamin D deficiency as a risk factor for renal scarring in recurrent urinary tract infections.

BACKGROUND: Renal scarring is a serious complication in recurrent urinary tract infections (UTIs). Vitamin D deficiency has also been reported to be a risk factor for UTIs although, to date, no association between vitamin D deficiency and renal scarring has yet been identified. In the present study, it was investigated whether vitamin D deficiency may be a risk factor for renal scarring in patients with recurrent UTIs. METHODS: The study included patients between the ages of 1 and 18 years who were admitted to the pediatric nephrology department of the center between November 1, 2018 and November 1, 2019 and who were diagnosed with recurrent UTIs. The medical records of the patients were reviewed for the collection of demographic data, vitamin D levels, ultrasonography results and scintigraphic investigations with 99m-technetium dimercaptosuccinic acid (99m Tc-DMSA). The patients were divided into two groups: those with and without renal scarring, diagnosed via 99m Tc-DMSA. The vitamin D levels and other parameters of the two groups were compared. RESULTS: Vitamin D deficiency (<20 ng/mL) was observed in 73.9% of the patients without renal scarring, and in 94.1% of those with renal scarring (P = 0.015). A logistic regression analysis revealed vitamin D deficiency to be an independent risk factor for renal scarring in patients with recurrent UTIs (OR = 0.796 [0.691-0.917]). CONCLUSIONS: Vitamin D deficiency is found to be a risk factor for renal scarring in patients with recurrent UTIs. Vitamin D treatment may contribute to the prevention of renal scarring in patients with recurrent UTI.

[Mortality Risk Factors for Invasive Candidiasis in Pediatric Intensive Care Unit]. / Çocuk Yogun Bakim Ünitesinde Invaziv Kandidiyaz Için Mortalite Risk Faktörleri.

Invasive Candida infections are one of the most important risk factors for the increasing mortality of immunocompromised patients with comorbidities in intensive care units. In this study, it was aimed to evaluate the mortality rate and risk factors affecting mortality in patients followed up with the diagnosis of invasive candidiasis in our pediatric intensive care unit. Patients who were between the ages of 1 month and 18 years followed up in the paediatric intensive care unit with invasive candidiasis between 2014 and 2018, were included in the study. The demographic characteristics of the patients, fever and hypotension, the Candida species, use of broad-spectrum antibiotics, blood transfusion, parenteral nutrition, invasive interventions, use of mechanical ventilation and laboratory test results were retrospectively analyzed and the relationship with mortality was statistically determined. A total of 85 patients, 45 girls, and 40 boys were included in the study. The death rate was 38.8% (n= 33). Candida albicans (48%) was the most common species for all isolates followed by Candida parapsilosis (21%), Candida tropicalis (15%), and others (16%). No statistically significant relationship was detected between the central venous catheter, broad-spectrum antibiotic and corticosteroid treatment, parenteral nutrition, gender difference, surgical operation, patient culture samples, isolated Candida species, and mortality (p> 0.05). A statistically significant relationship was found between blood transfusion, thrombocytopenia, and leukopenia, the first positive culture time since hospitalization, and the duration of antibiotic treatment and mortality (p<0.05). A statistically significant correlation was found with the presence of hypotension, one of the clinical markers associated with mortality (p<0.05) but the same relationship was not found with the presence of fever (p> 0.05). The mortality rate is high in candidiasis patients in pediatric intensive care units. Blood transfusions, long-term use of broad-spectrum antibiotics, and hypotension increase mortality.

Fetal anatomy of the facial nerve trunk and its relationship with posterior auricular artery.

PURPOSE: The aims of the study are to define anatomy of the facial nerve (FN) and its main trunks as well as their relationship with the posterior auricular artery in fetal period to evaluate the data for regional surgery in newborns and young infants. METHODS: Formalin-fixed 34 fetuses from anatomy laboratory collection with a mean gestational age of 26.4 ± 4.6 (20-36) weeks were dissected. Parameters regarding the presence of major or minor trunks, width, length, branching pattern of FN were evaluated according to side, gender and trimester. The positional relationship of posterior auricular artery with the FN trunk was inspected. RESULTS: On all sides only the major trunk of the FN was detected. For length and width parameters, there was no statistically significant difference for side and gender except for trimester. Linear functions were found as 0.329 + 0.025 × weeks for width and 5.264 + 0.185 × weeks for length. There are statistically significant linear relationships between width and length of the FN trunk and week parameters as r = 0.507, p < 0.001 and r = 0.484, p < 0.001, respectively. Posterior auricular artery crossed FN trunk laterally in 42 of 53 sides, medially in 9 sides while it was puncturing it proximally in 2 sides. In all cases, it was in close contact to the FN trunk. FN trunk showed bifurcation in 82% and trifurcation in 18%. CONCLUSION: Dimensions of FN trunk, growth ratio and linear functions can be beneficial in understanding the fetal growth of FN trunk and its usage for grafts. Data about the relationship of the posterior auricular artery with FN trunk may be crucial in avoiding iatrogenic injuries during surgery in early ages.

Morphometric properties of the latissimus dorsi muscle in human fetuses for flap surgery.

PURPOSE: Although latissimus dorsi (LD) flaps are extensively used in a wide range of interventions, fetus studies on this subject are quite limited. This study aims to obtain detailed information about the morphometric features of LD, thoracodorsal artery (TDA) and nerve (TDN). METHODS: The study was carried out on both sides of 50 formalin-fixed human fetuses (22 male/28 female) with a mean gestational age of 24.5 ± 4.7 (range 18-36) weeks, which were in the inventory of Anatomy Department of Mersin University Faculty of Medicine. Dimensions of LD, lengths and width of TDA and TDN were measured. Surface area of LD was calculated using digital image analysis software. RESULTS: All samples had LD muscle. Neither gender nor side-significant differences were observed in relation with the numerical data of LD, TDN and TDA. Linear function of surface area was calculated as "y = - 1767.532 + 114.582 × Age (weeks)". LD was attached directly to the posterior part of iliac crest in 59 of 100 sides meanwhile in the rest 41, it was attached by the thoracolumbar fascia. TDA gave a branch to serratus anterior in 96 cases and 2 branches in 4 cases. TDN passed superficial to TDA in 84 and deep to TDA in 16 samples. TDN had bifurcation in 93, trifurcation in 6 and tetrafurcation in 1 side. CONCLUSION: Data obtained from this study can be useful for estimating the sizes of LD and related neurovascular structures, especially in neonate surgeries. Linear function of LD surface area can be helpful to design the flap dimensions in newborn surgeries. A throughout knowledge about the branching pattern of TDN and its location-wise relation with TDA should be kept in mind to prevent possible complications during harvesting LD flaps and TDN grafts.

Sleep problems in pediatric epilepsy and ADHD: The impact of comorbidity.

AIMS: Attention-deficit hyperactivity disorder (ADHD) is a frequent comorbidity in pediatric epilepsy. Although sleep problems are commonly reported in both children with primary ADHD and epilepsy, those with epilepsy-ADHD comorbidity have not been well studied. This study aimed to compare sleep problems among three groups of children: 1) children with epilepsy, 2) children with epilepsy and ADHD (epilepsy-ADHD), and 3) children with primary ADHD. METHODS: 53 children with epilepsy, 35 children with epilepsy-ADHD, and 52 children with primary ADHD completed the Children's Sleep Habits Questionnaire (CSHQ). Neurology clinic charts were reviewed for the epilepsy-related variables. ADHD subtypes were diagnosed according to the DSM-IV. RESULTS: Children with epilepsy-ADHD had the highest CSHQ total scores, while children with primary ADHD had higher scores than those with epilepsy. Besides the total score, epilepsy-ADHD group differed from the primary ADHD and epilepsy groups with higher CSHQ subscores on sleep onset delay and sleep anxiety. The frequency of moderate-severe sleep problems (CSHQ>56) was 62.9% in children with epilepsy-ADHD, while it was 40.4% and 26.4% in children with primary ADHD and epilepsy, respectively. CSHQ total scores were not different between ADHD subtypes in both children with epilepsy-ADHD and those with primary ADHD. None of the epilepsy-related variables were found to be associated with CSHQ scores. DISCUSSION: Epilepsy-ADHD is associated with a significantly poor sleep quality which is beyond that of primary ADHD and epilepsy.

The effectiveness of the COPE healthy lifestyles TEEN program: a school-based intervention in middle school adolescents with 12-month follow-up.

AIM: The goal of this study is to assess the applicability and long-term effectiveness of the T-COPE Healthy TEEN program on adolescent health. BACKGROUND: Obesity and mental health disorders are major public health problems in adolescents. In this context, including long-term and multiple behavioural obesity prevention programs are becoming increasingly important. DESIGN: A quasi-experimental design with pre-test/post-test control group and repeated measurements. METHODS: Eighty-seven (45 in intervention group, 42 in control group) adolescents were included from two different middle schools in the intervention program. The data were analysed by using descriptive statistics, Pearson chi-square, Fisher's exact test, Student-t test, repeated measures of variance analysis and Cohen's d effect size. RESULTS: No significant difference was found between the intervention and control groups in terms of descriptive characteristics, behavioural and cognitive variables of the adolescents. Following the intervention, the adolescents in intervention groups showed improvements in nutritional behaviour, physical activity and stress management. These improvements concerned increased physical walking measured in the number of physical steps per week daily fruit and vegetable consumption and the daily quantity of water ingested. While their nutrition/physical activity knowledge significantly increased, their weight and anxiety symptoms significantly decreased. The effect of the program on body mass index, depression and health beliefs of the adolescents were not significant compared with the control group. CONCLUSION: The applicability of the T-COPE Healthy TEEN program on Turkish adolescents and its effectiveness on their health behaviours, nutrition and physical activity knowledge and stress management were revealed in this study.

The organisational silence of midwives and nurses: reasons and results.

AIM: The study was conducted to determine the issues about which nurses and midwives remain silent and the reasons for it and the perceived results of silence. BACKGROUND: Organisational silence is a vitally important issue in the health sector, due to the risks and mistakes that are not reported, and proposals for improvement that are not made. METHOD: The sample of this descriptive survey, which investigated a cause and effect relationship, was 159 nurses and midwives. The data were collected using a questionnaire and the organisational silence scale. FINDINGS: Of the study participants, 84.9% were nurses and 15.1% were midwives. Of all participants 88.7% were women. 8.8% of participants stated that they never remained silent about issues related to work and the workplace. Respondents most often remained silent about issues related to ethics and responsibility. 'Limited improvement and development' was frequently mentioned as a perceived result of organisational silence. CONCLUSION: Our study determined that organisational silence is quite common among nurses and midwives. IMPLICATIONS FOR NURSING MANAGEMENT: Activities that raise the awareness of hospital administrations and employees about preventing the factors that cause and maintain silence in hospitals should be planned.

Fibroblast growth factor 2 improves cognitive function in neonatal rats with hypoxic ischaemic brain injury.

OBJECTIVE: To determine the effect of fibroblast growth factor 2 on cognitive function in neonatal rats with hypoxic-ischaemic brain injury. METHODS: The randomised controlled study was conducted from January to June 2011 at Mersin University, School of Medicine, Experimental Animals Research Laboratory and Physiology Behaviour Laboratory, Mersin, Turkey. It included 7-d-old male rats that were randomised into four groups: fibroblast growth factor 2-20, fibroblast growth factor 2-40, control and sham. All the rats, except those in the sham group, were kept in a hypoxia chamber containing 8% oxygen for 2 hours following ligation of the right carotid artery. After hypoxic-ischaemic brain injury was induced, 20 ng g-1 or 40 ng g-1 of fibroblast growth factor 2 was administered via the intraperitoneal route. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelling method was used to evaluate neuronal apoptosis. The Morris water maze (MWM) test was administered to the rats at age 14 weeks. RESULTS: Of the 78 rats on the study, 18 (23%) were in the sham group, while the other three groups had 20 (25.6%) rats each. The number of apoptotic neurons in the right hemisphere in the experimental groups was significantly lower than in the control group (p=0.004 and p<0.001). The number of apoptotic neurons in the right hemisphere in the fibroblast growth factor 2-40 group was significantly lower than in the fibroblast growth factor 2-20 group (p<0.001). Moreover, fibroblast growth factor 2improved Morris water maze test cognitive performance in a dose-dependent manner. CONCLUSIONS: Fibroblast growth factor 2 treatment reduced neuronal apoptosis and improved cognitive functioning in neonatal rats with experimentally-induced hypoxic-ischaemic brain injury.

Using mobile phone text messages to improve insulin injection technique and glycaemic control in patients with diabetes mellitus: a multi-centre study in Turkey.

AIM AND OBJECTIVES: To improve the knowledge and skills of diabetic patients on insulin injections using mobile phone short message services and to evaluate the association of this intervention with metabolic outcomes. BACKGROUND: Mobile communication technologies are widely used in Turkey, which maintains a diabetic population of more than 6·5 million. However, there are a limited number of studies using mobile technologies in the challenging and complicated management of diabetes. DESIGN: A one group pretest-posttest design was used in this study. METHODS: The study sample consisted of 221 people with type 1 and type 2 Diabetes Mellitus from eight outpatient clinics in six cities in Turkey. The 'Demographic and diabetes-related information Form' and 'Insulin Injection Technique and Knowledge Form' were used in the initial interview. Subsequently, 12 short messages related to insulin administration were sent to patients twice a week for six months. Each patient's level of knowledge and skills regarding both the insulin injection technique and glycaemic control (glycated haemoglobin A1c) levels were measured at three months and six months during the text messaging period and six months later (12 months total) when text messaging was stopped. RESULTS: The mean age of the patients with diabetes was 39·8 ± 16·2 years (min: 18; max: 75). More than half of the patients were females with a mean duration of diabetes of 11·01 ± 7·22 years (min 1; max: 32). Following the text message reminders, the patients' level of knowledge and skills regarding the insulin injection technique improved at month 3 and 6 (p < 0·05). The patients' A1c levels statistically significantly decreased at the end of month 3, 6 and 12 compared to the baseline values (p < 0·05). The number of insulin injection sites and the frequency of rotation of skin sites for insulin injections also increased. CONCLUSION: This study demonstrated that a short message services-based information and reminder system on insulin injection administration provided to insulin-dependent patients with diabetes by nurses resulted in improved self-administration of insulin and metabolic control. RELEVANCE TO CLINICAL PRACTICE: Today, with the increased use of mobile communication technologies, it is possible for nurses to facilitate diabetes management by using these technologies. We believe that mobile technologies, which are not only easy to use and to follow-up with by healthcare providers, are associated with positive clinical outcomes for patients and should be more commonly used in the daily practice of diabetes management.

MPV and other inflammatory markers in diagnosing acute appendicitis.

OBJECTIVE: To investigate whether mean platelet volume can be used as an inflammatory marker for the diagnosis of acute appendicitis, and to determine the role, if any, of white blood cell count, C-reactive protein and neutrophil count in this regard. METHODS: The retrospective study was conducted at Mersin University (MEU) Health Research and Application Center, Emergency Department, Mersin, Turkey, and included medical record of patients having gone appendectomy between April 2012 to July 2013. Based on pathology examination, the cases were grouped as uncomplicated, complicated, and non-appendicitis cases. Preoperative white blood cell, neutrophil, C-reactive protein and mean platelet volume were noted. SPSS 16 was used for statistical analysis. RESULTS: Records of 275 patients were studied. Overall, 90(32.7%) patients were uncomplicated, 120(43.7%) complicated, and 65(23.6%) were non-appendicitis cases. The first two groups had a significantly higher white blood cell (p=0.001) and neutrophil (p<0.001) counts than the third one. Mean platelet volume levels were not statistically different (p=0.478).The neutrophil count had a sensitivity of 76.19%, specificity of 56.92%, positive predictive value of 85.11%, and negative predictive value of 42.53%; white blod cell count had sensitivity 68.10%, specificity 61.54%, positive predictive value 85.12%, and negative predictive value 37.38%; mean platelet volume level had sensitivity 74.76%, specificity 35.38%, positive predictive value 78.89%, and negative predictive value 30.26%; and C-reactive protein level had sensitivity 84.29%, specificity 30.77%, positive predictive value 79.73%, and negative predictive value 37.74%. CONCLUSIONS: Elevated white blood cell and neutrophil counts may be used as diagnostic tests in cases of acute appendicitis, while C-reactive protein and mean platelet volume levels were not useful as diagnostic markers.

Phleboviruses are enveloped segmented RNA viruses, capable of inducing febrile disease and/or meningoencephalitis in exposed individuals, according to the infecting strain, following transmission via arthropods. Prototype medically-important phlebovirus strains responsible for sandfly fever are sandfly fever Sicilian virus (SFSV) and sandfly fever Naples virus (SFNV), where the SFSV variant sandfly fever Cyprus virus (SFCV) is also detected in individuals with febrile disease. Toscana virus (TOSV) is unique among phleboviruses as the cause of infections involving central nervous system. In this seroepidemiological study, human exposure to selected medically-important phleboviruses was investigated in healthy adult residents of the Mersin province, Mediterranean Anatolia, Turkey, where the current data on phlebovirus epidemiology is scarce. A total of 1784 healthy individuals (mean age: 34.7±9.6 years; 97.3% were male), accepted as blood donors at the Mersin University Center for Health Research and Application Blood Bank were included in the study after informed consent during a seventeen month period between July 2011 to November 2012. All participants were requested to fill out a questionnaire to reveal risk factors for vector exposure. SFSV, SFNV, SFCV and TOSV IgG antibodies in serum were investigated via a commercial indirect immunofluorescence test (IIFT) (Sandfly Fever Virus IgG Mosaic I; Euroimmun, Germany). Sera interpreted as positive or strong positive for TOSV or SFNV+TOSV in IIFT were evaluated via TOSV virus neutralization test (VNT) for specificity confirmation. IIFT seroreactivity for at least one of the tested phleboviruses was present in 66.8% (1192/1784) of the samples. The most frequently-detected phlebovirus strain was SFSV (51.6%; 920/1784), followed by SFNV (46.4%; 827/1784), TOSV (43.7%; 779/1784) and SFCV (47.3%; 843/1784). Among the reactive sera, 6.6% (79/1192) were positive for a single virus serotype, whereas in 39.8% (475/1192) antibodies reacting with all tested virus serotypes were revealed. A total of 187 sera was included in the TOSV VNT and neutralizing antibodies were detected in 13.9%. According to the IIFT reactivity, residing in rural areas was observed as a statistically significant risk factor for exposure in all phleboviruses tested (p values for SFSV, SFNV, TOSV and SFCV were 0.002, 0.001, <0.001 and 0.003, respectively). TOSV exposure is more frequently detected via IIFT in individuals having pets or domestic farm animals around the living quarters (p=0.005). As a result, frequent exposure to SFSV/SFCV or antigenically similar phlebovirus strains and viruses of the SFNV species were determined in healthy blood donors in Mersin province, located in the Mediterranean region of Turkey. Furthermore, TOSV neutralizing antibodies were detected in selected samples with IIFT reactivity, confirming previous reports suggesting TOSV activity in the region. TOSV and other phleboviruses must be included in the diagnostic work-up in cases with febrile diseases and viral central nervous system infections during the sandfly-active months.

Neuroprotective effect of levetiracetam on hypoxic ischemic brain injury in neonatal rats.

PURPOSE: Hypoxic-ischemic brain injury that occurs in the perinatal period is one of the leading causes of mental retardation, visual and auditory impairment, motor defects, epilepsy, cerebral palsy, and death in neonates. The severity of apoptosis that develops after ischemic hypoxia and reperfusion is an indication of brain injury. Thus, it may be possible to prevent or reduce injury with treatments that can be given before the reperfusion period following hypoxia and ischemia. Levetiracetam is a new-generation antiepileptic drug that has begun to be used in the treatment of epilepsy. METHODS: The present study investigated the effects of levetiracetam on neuronal apoptosis with histopathological and biochemical tests in the early period and behavioral experiments in the late period. RESULTS: This study showed histopathologically that levetiracetam reduces the number of apoptotic neurons and has a neuroprotective effect in a neonatal rat model of hypoxic-ischemic brain injury in the early period. On the other hand, we demonstrated that levetiracetam dose dependently improves behavioral performance in the late period. CONCLUSIONS: Based on these results, we believe that one mechanism of levetiracetam's neuroprotective effects is due to increases in glutathione peroxidase and superoxide dismutase enzyme levels. To the best of our knowledge, this study is the first to show the neuroprotective effects of levetiracetam in a neonatal rat model of hypoxic-ischemic brain injury using histopathological, biochemical, and late-period behavioral experiments within the same experimental group.
