The validity and reliability of Turkish version of the self-efficacy scale in nursing care of children with epilepsy.

PURPOSE: This study was conducted to the Turkish validity and reliability study of the 'Scale of Self-efficacy in Nursing Care of Children with Epilepsy' (SSENCCE). DESIGN AND METHODS: The construct validity of the scale was evaluated with explanatory factor analysis (EFA) and confirmatory factor analysis. The reliability of the scales used in the research was examined with composite reliability and Cronbach's alpha coefficients. RESULTS: A total of 144 nurses participated in the study. The variance explained in the 12-item scale was 53.6%, and the eigenvalue was found as 6.442. The commonality values of the scale items ranged from 0.304 to 0.712, and the factor loads ranged from 0.552 to 0.844. Cronbach's α of the SSENCCE was calculated as 0.907. CONCLUSION: The Turkish version of the ESSENCE is a valid, reliable, and appropriate tool for assessing the self-efficacy of nurses providing care for children with epilepsy. PRACTICE IMPLICATIONS: Considering that there is no scale that is used to evaluate the self-efficacy of nurses who provide care for children with epilepsy in Turkey, it is thought that this study will guide future research on the subject and the improvement of the clinical experience of nurses.

Relationship of Gratitude and Coping Styles with Depression in Caregivers of Children with Special Needs.

This is a cross-sectional, descriptive and correlational study aiming to reveal the relationship of gratitude and coping styles with depression in caregivers of children with special needs. As a result of the study, which was conducted with 330 caregivers, it was determined that the caregivers' level of gratitude was high. In this study, it was found that the caregivers used mostly turning to religion, planning, positive reinterpretation, and instrumental social support as coping styles respectively. It was established that there was a significant correlation between caregivers' depression level and gender, education level, level of gratitude, focus on and venting of emotions, substance use, behavioural disengagement, positive reinterpretation, using emotional social support and planning coping styles. The depression disclosure level was found to be 17.8%. For holistic nursing care, the assessment of spiritual care and spiritual needs of caregivers is very important because of its positive effect on mental health.

The effects of desert dust storms, air pollution, and temperature on morbidity due to spontaneous abortions and toxemia of pregnancy: 5-year analysis.

Epidemiological studies have suggested an association between particulate air pollution, increased temperatures, and morbidity related to pregnancy outcomes. However, the roles of desert dust storms and climatological factors have not been fully addressed. The objectives of the present study were to investigate the association between desert dust storms, particulate matter with a diameter ≤10 µm (PM10), daily temperatures, and toxemia of pregnancy and spontaneous abortion in Gaziantep, South East Turkey. The study was conducted retrospectively at emergency department of two hospitals in Gaziantep city. Data from January 1, 2009, to March 31, 2014, were collected. Patients, who were diagnosed with toxemia of pregnancy and spontaneous abortion by radiological imaging modalities, were included in the study. Daily temperature ranges, mean temperature values, humidity, pressure, wind speed, daily PM10 levels, and records of dust storms were collected. A generalized additive regression model was designed to assess variable effects on toxemia of pregnancy and spontaneous abortion, while adjusting for possible confounding factors. Our findings demonstrated that presence of dust storms was positively associated with the toxemia of pregnancy both in outpatient admissions (OR=1.543 95% CI=1.186-2.009) and inpatient hospitalizations (OR=1.534; 95% CI=1.162-2.027). However, neither PM10 nor maximum temperature showed a marked association with spontaneous abortion or toxemia of pregnancy in our study population. Our findings suggest that desert dust storms may have an impact on the risk for adverse pregnancy outcomes such as toxemia of pregnancy. Health authorities should take necessary measures to protect pregnant women against detrimental effects of these storms.

Effect of a novel extracorporeal cytokine apheresis method on endocan, copeptin And interleukin-6 levels in sepsis: An observational prospective study.

PURPOSE: There is still an evident need for useful biomarkers and effective therapeutic approaches regarding the challenging management of sepsis. The aim of the study is to evaluate the effect of each Cytosorb hemoadsorption therapy course on blood levels of inflammatory biomarkers of sepsis including endocan, copeptin, interleukin-6, procalcitonin, C-reactive protein. METHODS: There were a total of 178 samples belonging to 34 patients that were diagnosed with sepsis and undergone Cytosorb therapy during the study period. Patient demographics were recorded. Arterial blood samples were obtained both before and and after each Cytosorb course. Levels of copeptin, interleukin-6, procalcitonin, C-reactive protein, erythrocyte sedimentation rate, white blood cell count, and creatinine were assessed both before and after each Cytosorb treatment. RESULTS: Levels of endocan, copeptin, interleukin-6, procalcitonin, C-reactive protein, and erythrocyte sedimentation rate were all significantly decreased after the Cytosorb course when compared with levels before therapy (p = 0.039, 0.001, 0.010, 0.001, 0.002 and 0.001, respectively). There was no significant difference between white blood cell count and creatinine levels before and after Cytosorb courses (p = 0.204 and 0.277). CONCLUSION: Cytosorb courses achieved significant decreases in endocan, copeptin, interleukin-6, procalcitonin and C-reactive protein levels. Decreasing plasma levels of inflammatory cytokines may help alleviate the cytokine storm and may have a role in improve outcomes. Further prospective randomized controlled studies with larger sample size are needed concerning the long-term effects of this decrease in cytokine levels on outcome and mortality.

Effect of Ramadan fasting on glycaemic parameters & body mass index in type II diabetic patients: A meta-analysis.

Background & objectives: There has been an ongoing debate about the impact of Ramadan fasting (RF) on the health of these individuals who fast during Ramadan. The aim of this meta-analysis was to evaluate the relationship between RF and glycaemic parameters in type 2 diabetes mellitus (T2DM) patients. Methods: Search terms were decided and databases such as MEDLINE EBSCO, Google Scholar and EMBASE were searched for eligible studies. Standardized mean differences and 95 per cent confidence intervals (CIs) of post-prandial plasma glucose (PPG), fasting plasma glucose (FPG), glycated haemoglobin (HbA1c) (%) and fructosamine levels were calculated for different treatment regimens. Results: Of the 40 studies, 19 were found eligible for inclusion in the meta-analysis. Based on pooled results, significant reductions in FPG were found in single oral antidiabetics (OAD) [standardized weighted mean difference (SMD)=0.47, 95% CI=(0.20-0.74)], multi-OAD [SMD=0.36, 95% CI=(0.11-0.61)] and multitreatment subgroups [SMD=0.65, 95% CI=(0.03-1.27)] and overall [SMD=0.48, 95% CI=(0.27-0.70)]. Furthermore, HbA1c(%) [SMD=0.26, 95% CI=(0.03-0.49)] and body mass index (BMI) [SMD=0.18, 95% CI=(0.04-0.31)] were significantly decreased in the multi-OAD group. Interpretation & conclusions: The meta-analysis showed that RF was not associated with any significant negative effects on PPG and fructosamine levels. However, BMI and FPG and HbA1c(%) were positively affected by RF.

Urinary angiotensinogen level is increased in renal transplant recipients with masked hypertension and is correlated with left ventricular mass index and albuminuria in these patients.

Activation of the local renin-angiotensin system (RAS) is an independent risk factor for the development of proteinuria and left ventricular hypertrophy (LVH) more commonly seen in masked hypertensives. It has been reported that urinary angiotensinogen (UAGT) level provides a specific index of the intrarenal RAS status. The aim of this study was to evaluate the association between UAGT and left ventricular mass index (LVMI) and urinary albumin-creatinine ratio (UACR) in renal transplant recipients (RTRs) with masked hypertension (HT). A total of 116 non-diabetic-treated hypertensive RTRs were included in this study. The patients were divided into two groups: masked hypertensives and controlled hypertensives. Forty-two (36.2%) of RTRs had masked HT. Mean UACR and LVMI levels were higher in RTRs with masked HT than in RTRs with controlled HT (P < 0.001). UAGT level was also higher in masked hypertensives compared to controlled hypertensives (P < 0.001). Multivariable regression analysis showed that UAGT was positively correlated with UACR (ß = 0.024, P = 0.001) and LVMI (ß = 0.082, P = 0.001) in masked hypertensives. Consequently, masked HT was considerably frequent (36.2%) in treated hypertensive RTRs and high UAGT levels accompanied by high albuminuria and LVMI levels were seen in these patients. Overproduction of the UAGT may play a pivotal role in the development of LVH and proteinuria in masked hypertensives.

Uteroglobin gene polymorphism (G38A) may be a risk factor in childhood idiopathic nephrotic syndrome.

BACKGROUND: Uteroglobin (UG) is a multifunctional protein with anti-inflammatory properties. The aim of this study was to first evaluate the role of UG gene G38A polymorphism in childhood idiopathic nephrotic syndrome (INS), and determine whether this variation may be related to the occurrence of INS or a steroid response. METHODS: One hundred and thirty-six children diagnosed with INS in Gaziantep University, Department of Pediatric Nephrology, and 70 healthy volunteers were included. Children with INS were divided into two groups: steroid-sensitive (n = 84), and steroid-resistant (n = 52). Samples were examined using the polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) enzyme method. RESULTS: The distributions of AA, GG, and AG genotypes of UG gene G38A (G/A) were 16.9%, 44.9%, and 38.2% in the all-INS group, whereas they were 14.3%, 48.8%, and 36.9% in the steroid-sensitive INS (SSINS) group compared with 21.1%, 38.5%, and 40.4% in steroid-resistant INS (SRINS), and 5.7%, 41.4%, and 52.9% in controls. The risk of INS was increased almost 4-fold in children with the AA genotype (p = 0.016). The risk of having SSINS was increased 3.5-fold (p = 0.042) whereas the risk of SRINS was increased 4.8-fold in the same genotype (p = 0.014). CONCLUSIONS: The uteroglobin gene may play an important role in the development of INS, and the AA genotype of UG gene G38A polymorphism was found more frequently in those children. Further studies evaluating all polymorphisms in larger patient groups are needed to exactly determine the effect of UG gene on the development of INS and steroid response in children.

Health-related quality of life and fall risk associated with age-related body composition changes; sarcopenia, obesity and sarcopenic obesity.

BACKGROUND: Sarcopenia, obesity, and sarcopenic obesity are various features of the ageing process that can cause important health issues. The present study was undertaken to investigate the interrelationship between those body composition changes, including their clinical components and the quality-of-life variables. METHODS: A total of 423 individuals aged 65 years or older was included in this cross-sectional study. Sarcopenia was diagnosed according to The European Working Group on Sarcopenia in Older People criteria. Body composition parameters were measured with a bioelectrical impedance analyser, and Turkish population-based cut-off points were preferred for diagnosis of sarcopenia. Comprehensive geriatric assessment was performed on all patients. A logistic regression analysis was performed to identify important factors for sarcopenia and sarcopenic obesity. RESULTS: The prevalence of sarcopenic, obese and sarcopenic obese subjects was 14%, 35% and 11% respectively. The lowest mean gait speed and hand grip strength values were seen in the sarcopenic obese group (0.6 ± 0.3 m/s and 19.7 ± 9.8 kg respectively). Sarcopenic obese participants were associated with the highest rate for fall risk. The scores for domains of health-related quality of life were worse in both obesity and sarcopenic obesity when compared to others. Body mass index (BMI), number of drugs used, total body fat ratio and geriatric depression scale-short form scores were negatively correlated with all dimensions of SF-36 quality-of-life scale. CONCLUSIONS: Sarcopenia, obesity and sarcopenic obesity are associated with many negative health outcomes, such as high fall risk and low health-related quality of life in geriatric population.

Comparison of IV dexketoprofen trometamol, fentanyl, and paracetamol in the treatment of renal colic in the ED: A randomized controlled trial.

OBJECTIVE: In this study, we aimed to compare the analgesic efficacy of intravenous dexketoprofen trometamol, fentanyl, and paracetamol in patients presenting to the emergency department with renal colic. MATERIALS AND METHOD: Data obtained from the emergency departments of Gaziantep University's Hospital for Research and Practice along with two other state hospitals in Gaziantep, Turkey between January 2016 and January 2017 was used for this study. A total of three hundred patients (n=300), who presented to the ER with complaints most common to renal colic whose diagnoses were subsequently confirmed with Computerized Tomography were included in the study. Patients' pain scores were recorded using the Visual Analogue Scale, at admission (immediately before drug administration), then at the 15th, and 30th minutes. SPSS 22.0 software package was used for analysis. p<0.05 was considered significant. RESULTS: At the 15th minute comparison, the efficacies of the three groups of drugs were not superior to one other, but at the 30th minute, dexketoprofen trometamol was statistically more effective than paracetamol and fentanyl. There was no statistically significant difference between fentanyl and paracetamol. The need for additional analgesia in the group receiving dexketoprofen trometamol was found to be lower. Dexketoprofen trometamol was statistically superior to the other two agents in achieving full analgesia at the end of the thirty-minute period. Fentanyl was found to be statistically significant in achieving moderate analgesia. CONCLUSION: As a Non-steroidal antiinflammatory drug dexketoprofen trometamol is superior to paracetamol and fentanyl in achieving analgesia and reducing the need for additional drugs for the treatment of renal colic.

Sorafenib with TACE improves the survival of hepatocellular carcinoma patients with more than 10 cm tumor: a single-center retrospective study.

PURPOSE: Sorafenib, a multikinase inhibitor, is effective in patients with advanced hepatocellular carcinoma (HCC). Transarterial chemoembolization (TACE) is an important palliative treatment for unresectable HCC, but TACE-induced ischemic injury can upregulate angiogenic factors and it might be associated with poor prognosis. The purpose of this study was to evaluate the efficacy of conventional TACE with or without sorafenib in patients with Barcelona Clinic Liver Cancer (BCLC) stage A-B HCC. METHODS: Thirty patients with BCLC stage A or B HCC who had undergone TACE were enrolled in this retrospective study. Child-Pugh score, BCLC staging classification, size and number of lesions were recorded. Sorafenib was given 1 month after TACE to some patients who responded to TACE. Repeated TACE was performed on demand. Tumor response was assessed every 12 weeks. The primary objective of this trial was the progression free survival (PFS). Secondary objectives were overall survival (OS), disease control rate (DCR) and total number of TACE interventions. Kaplan-Meier method was used for the estimation of survival and survival curves were compared with Log-rank test. RESULTS: Twenty-five (83.3%) patients had Child-Pugh A and 5 (16.7%) Child-Pugh B, and 24 (80%) patients had BCLC stage B disease and remanining had stage A disease. Lesion size >10 cm was found in 6 patients and 16/7/7 patients had single/two/multiple lesions, respectively. Mean number of TACE was 2.10±1.369. Seventeen (56.7%) patients used sorafenib after TACE whereas 13 (43.3%) patients were followed without any treatment but received consequent TACEs if needed. PFS of all patients was 10 months (range 3-48); it was 13 months for TACE plus sorafenib group and 9 months for TACE group (p=0.081). In subgroup analysis, TACE plus sorafenib group had better PFS (36 vs 12 months) in patients with tumor size > 10 cm (p=0.025). In the analysis of Child- Pugh A cases, PFS of TACE plus sorafenib group was 23 months while it was 10 months in TACE group (p=0.007). CONCLUSION: Concurrent treatment in Child-Pugh A group HCC with conventional TACE and sorafenib demonstrates a significant efficacy in patients having tumor size >10 cm. In Child-Pugh A group, PFS was superior in the sorafenib plus TACE group than in TACE alone group.

Efficacy of venlafaxine for the relief of taxane and oxaliplatin-induced acute neurotoxicity: a single-center retrospective case-control study.

BACKGROUND: Oxaliplatin and taxane-induced neurosensory toxicity is dose-limiting and mostly presents with acute symptoms that affect the activities of daily living and overall quality of life. The objective of the present study is to assess the relief of acute neuropathy with venlafaxine treatment during the chemotherapy period. PATIENTS AND METHODS: In this retrospective case-control study, from January 2010 to February 2015, patients who experienced treatment with oxaliplatin and taxane-induced acute neurotoxicity were evaluated according to the NCI-CTCAE v. 4.03 grading scale. Neurotoxicity was evaluated using a numeric rating scale (NRS) for pain intensity and experienced relief under the treatment of venlafaxine and using a neuropathic pain symptom inventory scale (NPSI) for the style of complaints. Patients who were diagnosed as mildly depressed according to the HOST anxiety and depression scale and who had grade 1 to 3 sensory neurotoxicity based on the NCI-CTCAE v. 4.03 grading scale, and who also reported ≥ 4/10 on a NRS were eligible. The primary end point was the rate of more than 75 % symptomatic relief under venlafaxine treatment. RESULTS: Two hundred six patients were included (82 % female, median age: 52.7 years). Most patients had breast, gynecologic, and colon cancer (93.4 %). Ninety-one patients who received venlafaxine and 115 patients as the control group were assessed for neurotoxicity every 3 weeks. Based on the NRS, a rate of more than 75 % symptomatic relief was 53.5, 58.3, and 45.2 % in venlafaxine arm versus 0, 0, and 0 % in the control arm in the first, second, and third visits, respectively. Side-effects of venlafaxine (n = 7) were grade 1-2 nausea/vomiting (3.2 %) and asthenia/somnolence (3.2 %) without grade 3-4 events. CONCLUSION: Venlafaxine has a significant clinical activity against taxane-oxaliplatin-induced acute neurosensory toxicity.

Taxane-induced peripheral sensorial neuropathy in cancer patients is associated with duration of diabetes mellitus: a single-center retrospective study.

PURPOSE: The purpose of this study was to determine whether the presence of diabetes mellitus (DM) influences the incidence and severity of peripheral sensory neuropathy (PSN) in patients using taxane therapy. METHODS: A retrospective single-center analysis was conducted: Patients with PSN at baseline were excluded. The incidence of PSN was evaluated retrospectively in patient subgroups who received taxane arm and taxane-plus-platinum-agents combination arm with or without known DM at baseline. RESULTS: Three hundred seventy-four patients were enrolled in this study, 81 (21.6%) of patients had DM at baseline. The incidence of grade 1 PSN (non-DM/DM) in patients receiving taxane-based chemotherapy was 33.4/25.9% and more than grade 2 PSN (non-DM/DM) was 15/34.6%. The rate of neuropathy of non-diabetic patients was 48.8%, while the rate of diabetic patients was 52.8 and 75% in DM duration below 5 years and above 5 years group, respectively. CONCLUSIONS: This retrospective analysis indicates that taxane-based therapy in DM patients whose disease duration is above 5 years appears to affect the incidence and severity of PSN without known baseline neuropathy. The probability of PSN with taxane-based therapy was similar in DM duration below 5 years and non-DM patients.

Delayed diagnosis: An important prognostic factor for oesophageal atresia in developing countries.

AIM: The aim of this study is to analyse the effect of delayed diagnosis on mortality rates, and evaluate the role of delayed diagnosis as a new prognostic factor in patients with oesophageal atresia (OA), especially in developing countries. METHODS: The records of 80 consecutive patients with OA (2008-2013) were reviewed. Patients were divided into two groups according to the time of diagnosis. As we demonstrated the effect of delayed diagnosis on mortality, we decided to develop a new classification that will be utilised to predict the prognosis of OA. The discrimination ability of the new prognostic classification was compared with those of the Waterston, Montreal and Spitz classifications using the area under the curve. RESULTS: The parameters of the new prognostic classification were birth weight less than 2000 g, the presence of major cardiac/life-threatening anomalies and delay in diagnosis. Class I consisted of patients with none or one of these parameters. Class II consisted of patients with two or three of these parameters. The area under the curve of the new classification was better than those of the other classifications in determining the prognosis of patients with OA. CONCLUSIONS: Delayed diagnosis of OA significantly led to morbidity and mortality. Although delayed diagnosis is not a characteristic of newborn or a marker of severity for OA and is a health care system issue in developing countries, we here point out that it is a prognostic factor in its own right. Our new classification has a superior discriminatory ability compared to the above-mentioned classifications.

Predictive factors for malignancy in patients with persistent cervical lymphadenopathy.

The aim of this study was to identify clinical factors that can predict malignancy in patients with persistent cervical lymphadenopathy. This retrospective study included 575 patients with persistent cervical lymphadenopathy who underwent surgical excision. The patients were divided into two groups according to their ages: group 1 (≤18 years) and group 2 (>18 years). Multiple logistic regression models and univariate analysis were performed to determine the association between clinical factors and malignancy. Male gender [odds ratio (OR) 4.184, 95 % confidence interval (CI) 1.823-9.602, p = 0.001], increased age (OR 1.072, 95 % CI 1.001-1.148, p = 0.046), left-sided lesions (OR 3.423, 95 % CI 1.407-8.329, p = 0.007), and larger lymph node size (OR 1.445, 95 % CI 1.021-2.044, p = 0.038) were significantly associated with malignancy in group 1. Male gender (OR 3.761, 95 % CI 2.361-5.992, p = 0.001), increased age (OR 1.015, 95 % CI 1.003-1.027, p = 0.018), duration of the disease (OR 0.770, 95 % CI 0.668-0.888, p = 0.001), and the presence of B symptoms (OR 4.996, 95 % CI 2.862-8.721, p = 0.001) were significantly associated with malignancy in group 2. The sensitivity and specificity of the models were 84 and 61.5 % for group 1 and 77.9 and 67.9 % for group 2, respectively. Increasing age and male gender were found to be associated with malignancy in all age groups. Larger lymph node size and left-sided lymphadenopathy were significant predictors of malignancy in children. Presence of B symptoms was found to be associated with malignancy in adults. Our results indicated that increasing duration of lymphadenopathy and the presence of bilaterality render the lymph node more likely to be benign in adults. No significant association was found between the involved neck site and malignancy for all age groups.

Plasma urotensin-2 level and Thr21Met but not Ser89Asn polymorphisms of the urotensin-2 gene are associated with migraines.

BACKGROUND: Urotensin-II (U-II) is a peptide recognized by its potent vasoconstrictor activity in many vascular events, however the role of urotensin-II in migraine has not been considered yet. The molecular mechanisms and genetics of migraine have not been fully clarified yet, but it is well-known that vascular changes considerably contribute in pathophysiology of migraine and also its complications. The aim of this study was to analyze the plasma U-II levels along with genotype distributions and allele frequencies for UTS2 Thr21Met and Ser89Asn polymorphisms among the patients with migraine without aura (MWoA). METHODS: One hundred eighty-six patients with MWoA and 171 healthy individuals were included in this study. Plasma U-II levels were measured in attack free period. The genotype and allele frequencies for the Thr21Met (T21M) and Ser89Asn (S89N) polymorphisms in the UTS2 gene were analyzed. RESULTS: Plasma U-II levels were significantly higher in MWoA patients (p = 0.002). We detected a significant association between the T21M polymorphism in the UTS2 gene and migraine (53.8 % in patients, 40.4 % in controls, p = 0.035), but not with S89N polymorphism (p = 0.620). A significant relationship was found between U-II levels and MIDAS score (ß = 0.508, p = 0.001). CONCLUSION: Our study suggests that U-II may play a role in migraine pathogenesis; also Thr21Met polymorphism was associated with the risk of migraine disease. Further studies are needed for considering the role of U-II in migraine pathophysiology and for deciding if UTS2 gene may be a novel candidate gene in migraine cases.

The association between weather conditions and stroke admissions in Turkey.

Although several factors such as cigarette smoking, blood pressure, diabetes, obesity, hypercholesterolemia, physical inactivity and dietary factors have been well documented to increase the risk for stroke, there are conflicting data about the role of meteorological variables in the etiology of stroke. We conducted a retrospective study to investigate the association between weather patterns, including daily temperature, humidity, wind speed, and air pressure, and stroke admissions to the Emergency Department of Atatürk Training and Research Hospital in Ankara, Turkey, between January 2009 and April 2010. Generalized additive models with logistic link function were used to investigate the relationship between predictors and days with and without stroke admission at lags 0-4. A total of 373 stroke patients were admitted to the emergency department (ED) between January 2009 and April 2010. Of patients, 297 had ischemic stroke (IS), 34 hemorrhagic stroke (HS), and 42 subarachnoidal hemorrhage (SAH). Although we did not find any association between overall admissions due to stroke and meteorological parameters, univariable analysis indicated that there were significantly more SAH cases on days with lower daily mean temperatures of 8.79 ± 8.75 °C as compared to relatively mild days with higher temperatures (mean temperature = 11.89 ± 7.94 °C, p = 0.021). The multivariable analysis demonstrated that admissions due to SAH increased on days with lower daily mean temperatures for the same day (lag 0; odds ratio (OR) [95% confidence interval (95% CI)] = 0.93 [0.89-0.98], p = 0.004) and lag 1 (OR [95% CI] =0.76 [0.67-0.86], p = 0.001). Furthermore, the wind speed at both lag 1 (OR [95% CI] = 1.63 [1.27-2.09], p = 0.001) and lag 3 (OR [95% CI] = 1.43 [1.12-1.81], p = 0.004) increased admissions due to HS, respectively. In conclusion, our study demonstrated that there was an association between ED admissions due to SAH and HS and weather conditions suggesting that meteorological variables may, at least in part, play as risk factors for intracranial hemorrhages.

Effectiveness and Safety of Selective Neck Dissection in Lymph Node-Positive Squamous Cell Carcinoma of the Head and Neck.

The aim of this study was to investigate the effectiveness and safety of selective neck dissection in patients with lymph node-positive head and neck squamous cell carcinoma to determine regional control and survival rates. Eighty patients with lymph node-positive head and neck squamous cell carcinoma who underwent selective dissection were included in the study. Regional control, survival rates, and factors affecting survival were analyzed. Regional control was 90%, disease-specific survival was 93.4%, and the overall survival rate was 87.25%. T stage, N stage, age, and extracapsular spread were included in hazard regression models. None of the factors were statistically significant. Selective neck dissection is an effective and oncologically safe treatment option in selected cases. T stage, N stage, and extracapsular spread had no significant impact on disease-specific survival.

Role of ACE I/D gene polymorphisms on the effect of ramipril in inflammatory response and myocardial injury in patients undergoing coronary artery bypass grafts.

BACKGROUND: Angiotensin-converting enzyme (ACE) inhibitors block angiotensin II formation and release bradykinin, which is effective in the regulation of oxidoinflammatory injury. Some reports denote alterations in the effectiveness of ACE inhibitors in association with ACE insertion/deletion (I/D) gene polymorphisms. This study investigates the effects of ramipril on the oxidoinflammatory cytokines (IL-6, IL-8, TNF-alpha) and TnT (myocardial injury marker) and their alteration in association with ACE I/D gene polymorphisms. METHODS: The study group (n = 51) patients received ramipril before coronary artery bypass grafting (CABG), while patients not receiving ramipril (n = 51) constituted the controls. TNFα, IL-6, and IL-8 were evaluated using ELISA and TnT by electrochemiluminescence methods before the induction of anesthesia (t1), at the 20th minute following cross-clamping (t2), at the end of the operation (t3), and at the 24th hour from the commencement of anesthesia (t4). Genotyping was performed by PCR. RESULTS: Differences between the groups were significant at t4 for the TNFα and at t3 for IL-6 (p < 0.05). The TnT levels increased from t2 onward in the control group and were highest in t3. Changes in t3 and t4 values in both groups according to their t1 values were significant (p < 0.05). However, differences between the groups were insignificant (p > 0.05). The IL-6, IL-8, TNFα, and TnT serum levels had no correlation with the ACE I/D gene polymorphism. CONCLUSION: Low cytokine and TnT levels in the study group, especially after cross-clamping, may indicate the protective effect of ramipril from oxidoinflammatory injury. This effect did not appear to be associated with the ACE I/D gene polymorphism.

Intraclass correlation coefficients for cluster randomized trials in care pathways and usual care: hospital treatment for heart failure.

BACKGROUND: Cluster randomized trials are increasingly being used in healthcare evaluation to show the effectiveness of a specific intervention. Care pathways (CPs) are becoming a popular tool to improve the quality of health-care services provided to heart failure patients. In order to perform a well-designed cluster randomized trial to demonstrate the effectiveness of Usual care (UC) and CP in heart failure treatment, the intraclass correlation coefficient (ICC) should be available before conducting a trial to estimate the required sample size. This study reports ICCs for both demographical and outcome variables from cluster randomized trials of heart failure patients in UC and care pathways. METHODS: To calculate the degree of within-cluster dependence, the ICC and associated 95% confidence interval were calculated by a method based on analysis of variance. All analyses were performed in R software version 2.15.1. RESULTS: ICCs for baseline characteristics ranged from 0.025 to 0.058. The median value and interquartile range was 0.043 [0.026-0.052] for ICCs of baseline characteristics. Among baseline characteristics, the highest ICCs were found for admission by referral or admission from home (ICC = 0.058) and the disease severity at admission (ICC = 0.046). Corresponding ICCs for appropriateness of the stay, length of stay and hospitalization cost were 0.069, 0.063, and 0.001 in CP group and 0.203, 0.020, 0.046 for usual care, respectively. CONCLUSION: Reported values of ICCs from present care pathway trial and UC results for some common outcomes will be helpful for estimating sample size in future clustered randomized heart failure trials, in particular for the evaluation of care pathways.
