Objective: Home program (HP) compliance is a crucial matter for parents of cerebral palsy (CP). A questionnaire is needed to determine the compliance and perceptions of parents of children with CP regarding the HP. The aim is to evaluate the structural validity, reliability, and responsiveness of Compliance and Perceptions of Parents of Children with Cerebral Palsy to Home Program Assessment Questionnaire (CPHP-Q). Methods: Parents of children with CP aged 2-18 years completed CPHP-Q (n=225). Among all participants, 70 individuals were randomly selected for responsiveness, and another 70 individuals were selected for reliability. Psychometric properties were evaluated using the intraclass correlation coefficient (ICC) and Cronbach’s Alpha for reliability, effect size (ES) and standard response mean (SRM) for responsiveness, and factor analysis for validity. Results: In parents with CP, CPHP-Q demonstrated high internal consistency (Cronbach’s alpha=0.96, ICC=0.93). Compliance and Perceptions of Parents of Children with Cerebral Palsy to Home Program Assessment Questionnaire showed significant responsiveness with ES value 1.31 and SRM value 1.29. Kaiser Meyer Olkin (KMO) was found to be significant with a value of 0.82. According to factor analysis, Chi-square/degrees of freedom (CMIN/DF)=2.25, The Root Mean Square Error of Approximation (RMSEA)=0.07, Goodness of Fit Index (GFI)=0.84, and comparative fit index (CFI)=0.93 were found. These values showed that model fit was good. Conclusion: The CPHP-Q is a valid, reliable, and responsive measure for HP adherence of parents of children with CP, and it is useful for determining HP implementation adherence and perceptions of parents but needs validation in other languages.

Introduction The study aims to understand the facilitators and barriers associated with enforcing and complying with Türkiye's smoke-free policy from the perspective of hospitality venue owners and employees. Methods A qualitative open-ended survey was conducted in Istanbul and Ankara in 2021 with 58 respondents from 3 different districts in each city from four types of venues: restaurants, traditional coffee and waterpipe houses, and European-style cafés. The open-ended survey included questions to understand the knowledge, beliefs, and attitudes of respondents about Türkiye's smoke-free policy and their perceptions of the facilitators and/or barriers to smoke-free policy implementation and changes after COVID-19. The data were analyzed using an inductive approach to identify patterns and categorize the data into themes. Results The respondents expressed that the smoke-free policy aimed to protect employees and customers from secondhand smoke (SHS), respect human health, and improve air quality. Findings suggest that the positive attitude of venue owners and staff toward the smoke-free policy serves as a facilitator. However, fear of financial impact, customers’ negative attitudes, difficulties in meeting physical requirements, and insufficient enforcement were found to be barriers to implementing the smoke-free policy. The effects of the COVID-19 pandemic were reported as an initial increase in compliance and awareness among customers and staff, but some respondents noted negative changes due to the emotional and financial effects of prolonged restrictions. These challenges have led to decreased attention on the smoke-free policy among venue owners, staff and customers. Respondents’ suggested improvements were related to building infrastructure, such as the ventilation systems and educating the public on the harmful health effects of smoking. Conclusions Despite the general understanding of the dangers of secondhand smoke and the smoke-free policy, this study highlights the challenges in implementing smoke-free policy measures and the continued need to raise awareness about the importance of a 100% smoke-free venue. A comprehensive approach to addressing the tobacco epidemic as a multifaceted public health issue is essential.

Objectives Thirty-day mortality (30 DM) is a measure of quality of cancer treatment and the predictors for 30 DM are important to identify vulnerable patients who are least likely to benefit from chemotherapy. We assessed the incidence and potential predictors of 30 DM in patients receiving chemotherapy. Methods All patients who received chemotherapy within an 8-month period in our hospital were assessed. Baseline prechemotherapy clinical features, vital signs, Modified Early Warning Scores (MEWS) and laboratory tests were recorded. Potential predictors of 30 DM were evaluated using multivariate logistic regression analysis. Results Among 4560 patients included, 77 patients (1.7%) died within 30 days of chemotherapy. Patients who died were older (62 vs 58, p=0.002), mostly males (61% vs 43%, p=0.006), had worse Eastern Cooperative Oncology Group performance scores (ECOG PS), and higher MEWS scores compared with those who survived. Multivariate analysis identified age >= 60 years (OR 2.2, 95% CI 1.2 to 4.1, p=0.01), male gender (OR 2.1, 95% CI 1.1 to 3.9, p=0.02), ECOG PS >= 3 (OR 3.2, 95% CI 1.1 to 8.8, p=0.03), pulse rate >= 90 bpm (OR 3.8, 95% CI 2.0 to 7.0, p<0.01), systolic blood pressure <110 mm Hg (OR 2.1, 95% CI 1.1 to 4.1, p=0.02), body mass index <25 kg/m2 (OR 2.1, 95% CI 1.1 to 3.8, p=0.02) and haemoglobin< 90 g/L (OR 14.2, 95% CI 4.3 to 46.6, p<0.01) to be associated with increased risk of 30 DM. Conclusions Along with well-known prognostic factors such as ECOG PS and disease stage, other simple and readily available parameters may predict early mortality after chemotherapy and produce a signal for the physicians to carefully reevaluate vulnerable patients before chemotherapy administration.

Abstract Background and Aims Anemia is observed from the early stages in the course of chronic kidney disease (CKD), and as the stage progresses, the severity of anemia and its impact on quality of life increase. Early diagnosis of anemia in chronic kidney disease, assessments related to its etiology, and treatment are therefore crucial. There is no comprehensive and long-term study in Turkey addressing the diagnostic and therapeutic management of anemia seen in the course of chronic kidney disease. The aim of this study is to investigate the frequency of anemia in different stages of CKD in patients diagnosed with Stage 3 and more advanced stages, to evaluate the effectiveness of diagnostic approaches, and management of iron parameters and anemia, and to investigate the effect of anemia on patient survival. We aim to present “real-life” data from this study to guide clinical practice and correct errors or deficiencies in anemia management. Method This study is a single-center, observational-descriptive retrospective study. 1321 outpatients with Stage 3A and advanced CKD and anemia who admitted to Hacettepe University Faculty of Medicine Nephrology Clinic between 2014 and 2018 were included in the study. Data for demographics, CKD etiologies and stages, anemia severities, comorbid diseases were collected from electronic health system (Table 1). Diagnostic investigations for anemia evaluation and therapeutic interventions such as administration of iron, folic acid, vitamin B12, erythropoiesis stimulating agents (ESA) were assessed. The long-term yield of diagnostic and therapeutic approaches and their effects on survival were also evaluated. The study investigated whether the severity of anemia and improvement in anemia had an effect on survival. Results Ferritin is the most commonly performed test for the etiology of anemia (76.4%). Request rates for tests such as B12, folic acid, transferrin saturation and reticulocyte are below 20%. More than half of the patients with anemia (59.4%) have not received any form of anemia treatment. Even among those whose ferritin test was checked and the value was &lt;100 µg/dL, only 41.4% were given iron treatment. As the clinical follow-up period of the patients increased, it was observed that anemia treatment was applied better and target values were reached more frequently (p &lt; 0.001). More than one third of the patients (34.8%) died during follow-up. The overall survival in patients whose anemia improved was 79.8%, and it was 62.8% in patients whose anemia did not improve the overall survival was (p = 0.002) (Fig. 1). When examining the relationship between survival status and anemia severity for the non-dialysis-dependent CKD Stage 3-5 group, there was a statistically significant survival difference between the Hb group of 10-11.9 g/dL to Hb group of &lt;10 g/dL (p = 0.004). Conclusion This study has shown that diagnostic tests for etiology of anemia were insufficiently ordered. It was also found that a significant majority of anemic patients who underwent etiological evaluation were not even adequately treated. Long-term follow up improved anemia treatment, and patients with improved anemia had better survival. In conclusion, we recommend an optimal evaluation of CKD patients with anemia and initiating treatment as early as possible.

AIMS:The International Lymphoma Radiation Oncology Group (ILROG) defined involved-site radiotherapy (ISRT) guidelines. These rules offer a certain variability that allows for autonomous decision-making in diverse clinical settings. However, this flexibility also gives rise to conflicts about the selection of treatment fields in the daily decision-making process. The aim of this study was to show the extent of interobserver variability when ILROG-ISRT recommendations were used in different clinical scenarios.MATERIALS AND METHODS:The 10-question survey used in our study consisted of two parts (part A and part B) and was prepared by four senior radiation oncologists experienced in the haemato-oncology field. The results were presented by stratifying according to clinical experience (<10 years, ≥10 years). Binomial tests (one-sided) were conducted to assess whether answers for each group and the whole group reached a consensus.RESULTS:Twenty-six radiation oncologists, 13 of whom had less than 10 years of experience and 13 seniors, participated in the survey. Eighty per cent of respondents thought ILROG did not bring sufficient solutions for all clinical scenarios but offered solutions in some cases. In different case-based scenarios, the consensus among the respondents decreased down to 38%. Senior radiation oncologists were found to have more doubts about the adequacy of current guidelines.CONCLUSIONS:ILROG guidelines allow for a high degree of variability in real-life clinical scenarios and different interpretation of the recommendations may lead to increased toxicity and recurrences. Therefore, there is a need for refinement in ISRT delineation strategies. On behalf of the Turkish Society for Radiation Oncology Hematological Oncology, Pediatric Oncology and TBI Study Group, we are planning to carry out further educational contouring sessions to detect the interobserver variability in real-life contouring cases.

In small children, acute dialysis (pediatric acute kidney support therapy (paKST)) is increasingly used; however, it is challenging for many reasons. We compared clinical characteristics and predictors of long-term outcomes of patients < 15 kg on peritoneal dialysis (PD), hemodialysis (HD), and continuous kidney replacement therapy (CKRT). Patients with history of paKST (CKRT, HD, PD) weighing < 15 kg and ≥ 6 months of follow-up at Hacettepe University were included. Surviving patients were evaluated at last visit. 109 patients (57 females) were included. Median age at paKST was 10.1 months (IQR: 2–27 months). In total, 43 (39.4

Objective: Cancers are the second most common cause of mortality following cardiovascular diseases in Turkey. Tobacco and obesity are the two major etiological factors for cancer progression, which are highly prevalent in Turkey. This study aimed to evaluate the new cancer cases in Turkey attributable to these two main risk factors. Material and methods: The tobacco-related cancers based on the International Agency for Research on Cancer (IARC) monographs were esophagus, oral cavity, gastric, pancreatic, larynx, lung, renal, and bladder cancers, and the obesity-related cancers based on the IARC's and World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) Continuous Update Project's reports were esophagus, colon, rectum, gallbladder, pancreas, kidney, ovary, endometrium, and breast cancers. The cancer incidences were obtained from the national cancer statistics. A lag time of at least 10 years was regarded adequate to observe the effects of past exposures on the new cancer cases. Prevalence of tobacco smoking was based on Peto-Lopez approach, and the obesity prevalence was obtained from the National Burden of Disease and Cost-Effectiveness Project Household Survey, 2003 Report in Turkey. Using these incidence and prevalence data, we estimated the population-attributable fractions (PAF) of cancers attributable to smoking and obesity in Turkey. Results: For tobacco-related cancers, the highest PAFs were found in lung cancer (89.8%), larynx cancer (86%), oral cavity and pharynx cancer (77.2%) in males, and larynx cancer (46.5%), lung cancer (43%), and esophagus cancer (31.4%) in females. For obesity-related cancers, the highest PAFs were found in esophagus adenocarcinoma (31.4%), kidney cancer (19.8%), gallbladder cancer (15.1%) in males, and esophagus adenocarcinoma (33.9%), endometrium cancer (32.8%), and postmenopausal breast cancer (22.8%) in females. When all tobacco-related cancers were considered, 41283 cases in males and 3853 cases in females were attributable to tobacco smoking, and when all obesity-related cancer types were considered, the number of attributable cancer cases to obesity was 2653 in men and 7387 in women Conclusion: The current situation of avoidable cancer burden in Turkey shows that eliminating the tobacco smoking and obesity may result with preventing more than 50000 cancer cases in Turkey.

Abstract Background/Aim To investigate the frequency and clinical relevance of an extended autoantibody profile in patients with systemic sclerosis (SSc). Materials and Methods In this cross‐sectional study, serum from 100 consecutive patients was subjected to indirect immunofluorescence (IIF) (HEp‐20‐10/primate liver mosaic) and Systemic Sclerosis Profile by EUROIMMUN to evaluate anti‐nuclear antibodies (ANA) and autoantibodies against 13 different autoantibodies in patients with SSc less than 3 years. Results Ninety‐three of 100 patients were positive for ANA by IIF. Fifty‐three patients showed single positivity, 26 anti‐topoisomerase antibodies (anti‐Scl70 ab), 16 anticentromere antibodies (ACAs), six anti‐RNA polymerase III antibodies (anti‐RNAPIII ab), one anti‐Ku antibody, one anti‐PM/Scl100 antibody, two anti‐PM/Scl75 antibodies, one anti‐Ro52 antibody, whereas 32 patients had multiple autoantibody positivities. Among classic SSc‐specific autoantibodies, anti‐Scl70 and anti‐RNAPIII abs showed the highest cooccurrence (n = 4). One patient was simultaneously positive for anti‐RNAPIII ab and ACA, and one was positive for ACA and anti‐Scl70 ab. The clinical features were not statistically different between single and multiple autoantibody‐positivity for classic SSc‐specific autoantibodies (ACA, anti‐Scl70 ab, and anti‐RNAPIII ab), except for digital ulcer in the multiantibody positive ACA group (p = .019). Conclusion Based on our results, coexpression of autoantibodies is not uncommon in SSc patients. Although autoantibodies specific to SSc in early disease show generally known clinical features, it remains to be investigated how the coexpression of autoantibodies will affect clinical presentation.

Glioblastoma is one of the most devastating neoplasms of the central nervous system. This study focused on the development of serum extracellular vesicle (EV)-based glioblastoma tumor marker panels that can be used in a clinic to diagnose glioblastomas and to monitor tumor burden, progression, and regression in response to treatment. RNA sequencing studies were performed using RNA isolated from serum EVs from both patients (n = 85) and control donors (n = 31). RNA sequencing results for preoperative glioblastoma EVs compared to control EVs revealed 569 differentially expressed genes (DEGs, 2XFC, FDR < 0.05). By using these DEGs, we developed serum-EV-based biomarker panels for the following glioblastomas: wild-type IDH1 (96% sensitivity/80% specificity), MGMT promoter methylation (91% sensitivity/73% specificity), p53 gene mutation (100% sensitivity/89% specificity), and TERT promoter mutation (89% sensitivity/100% specificity). This is the first study showing that serum-EV-based biomarker panels can be used to diagnose glioblastomas with a high sensitivity and specificity.

We aimed to evaluate the seroconversion rates after two doses of inactive COVID-19 vaccine (CoronaVac) and the benefit of a third dose mRNA vaccine booster in patients with cancer receiving active treatment. Patients with solid tumors receiving active treatment (n = 101) and patients with no-cancer (n = 48) as the control group were included in the study. All the patients and controls had received two doses of CoronaVac and a third booster dose of the mRNA vaccine (Bnt162b2). Anti-SARS-CoV-2 Spike Receptor Binding Domain IgG antibody levels after the second and third dose were measured with quantitative ELISA. The median age of the patients was 66 (IQR 60-71). 79% of the patients were receiving chemotherapy, and 21% were receiving immunotherapy at the time of vaccination. Antibody levels measured after two doses of CoronaVac were significantly lower in patients with cancer than in the control group (median 0 mu g/ml [IQR 0-1.17 mu g/ml] vs median 0.91 mu g/ml [IQR 0-2.24 mu g/ml], respectively, P = .002). Seropositivity rates were 46.5% in patients with cancer and 72.9% in the control group (P = .002). Antibody measurement was performed in 26 patients after the third dose. Seroconversion rate increased from 46.5% to 88.5% (P < .001), and the antibody titers significantly increased with the third-dose booster (median 0 mu g/ml [IQR 0-1.17 mu g/ml] after two doses vs 12.6 mu g/ml [IQR 1.8-69.1 mu g/ml] after third booster dose, P < .001). Immunogenicity of CoronaVac is low in patients with cancer receiving active treatment, and administering a third dose of an mRNA vaccine is effective in terms of improving seroconversion rates.

OBJECTIVES:Nephrotoxicity is the most serious and common adverse effect that limits the use of polymyxins. This study compared polymyxin E (colistin) and polymyxin B regarding drug-related nephrotoxicity. METHODS:This study was conducted as a retrospective cohort study in a university hospital between January 2020 and July 2022. Patients older than 18 years and who received colistin or polymyxin B were identified using electronic hospital records. Kidney disease improving global outcome criteria were used for assessing nephrotoxicity. RESULTS:A total of 190 patients, 95 in both groups, were evaluated. The incidence of acute kidney injury during the treatment was higher in the colistin group [52.6% (n = 50) and 34.7% (n = 33), P = 0.013]. In patients who were exposed to high-dose, the rate of nephrotoxicity was higher in patients receiving colistin [25% (n = 3) vs. 76.9% (n = 10); P = 0.017]. Nephrotoxicity was reversible in 64.4% (n = 38) of patients and the reversibility rate was similar (70% and 52.6% for colistin and polymyxin; P = 0.248). In the multivariable analysis, colistin treatment [odds ratio (OR): 3.882, 95% confidence interval (95% CI) = (1.829-8.241)], concomitant vasopressor use (OR = 2.08, CI: 1.036-4.179), and age (OR=1.036, CI: 1.014-1.058) were found to be independent markers of nephrotoxicity. CONCLUSION:Nephrotoxicity was more common in patients receiving high-dose colistin than polymyxin B. Therefore, the use of appropriate doses of colistin is important in terms of preventing nephrotoxicity. In addition, advancing age and concomitant use of vasopressors contribute to polymyxin-related nephrotoxicity.

Background/aim Little is known about the prevalence and causes of pulmonary hypertension (PH) in Behçet’s disease (BD). This study was conducted to determine the prevalence and causes of PH in BD. Materials and methods In this descriptive study, we screened 154 patients with BD for PH using transthoracic echocardiography between February 2017 and October 2017. An estimated systolic pulmonary arterial pressure (sPAP ≥ 40 mmHg) was used as the cut-off value to define PH. Patients with BD were categorized into 5 groups according to organ involvement including mucocutaneous/articular, ocular, vascular, gastrointestinal, and neurologic involvement. Additional laboratory and imaging results were obtained from hospital file records to determine the causes of PH. Results PH was detected in 17 (11%) patients. Nine (52.9%) of these patients had group II PH (due to left heart disease), 4 (23.5%) had IV PH (due to pulmonary arterial involvement), and 1 had III PH (due to chronic obstructive lung disease). The frequency of PH was higher in BD patients with vascular involvement than those without (52.9% vs 28.5%; p = 0.04). Among 10 patients with pulmonary artery involvement (PAI) 4 (40%) had PH. Although the vascular BD group had the highest rate of PH, we observed no statistically significant difference in the frequency of PH between the predefined BD subgroups. Conclusions PH is not rare in patients with BD. The majority of BD patients with PH are in group II or IV PH. Patients with vascular involvement carry a higher risk for the development of PH. Monitoring BD patients with PAI should be considered for the development of group IV PH.

BACKGROUND:Alport syndrome (AS) is characterized by progressive kidney disease. There is increasing evidence that renin-angiotensin-aldosterone system (RAAS) inhibition delays chronic kidney disease (CKD) while the effectiveness of immunosuppressive (IS) therapy in AS is still uncertain. In this study, we aimed to analyze the outcomes of pediatric patients with X-linked AS (XLAS) who received RAAS inhibitors and IS therapy.METHODS:Seventy-four children with XLAS were included in this multicenter study. Demographic features, clinical and laboratory data, treatments, histopathological examinations, and genetic analyses were analyzed retrospectively.RESULTS:Among 74 children, 52 (70.2%) received RAAS inhibitors, 11 (14.9%) received RAAS inhibitors and IS, and 11 (14.9%) were followed up without treatment. During follow-up, glomerular filtration rate (GFR) decreased < 60 ml/min/1.73 m2 in 7 (9.5%) of 74 patients (M/F=6/1). In male patients with XLAS, kidney survival was not different between RAAS and RAAS+IS groups (p=0.42). The rate of progression to CKD was significantly higher in patients with nephrotic range proteinuria and nephrotic syndrome (NS), respectively (p=0.006, p=0.05). The median age at the onset of RAAS inhibitors was significantly higher in male patients who progressed to CKD (13.9 vs 8.1 years, p=0.003).CONCLUSIONS:RAAS inhibitors have beneficial effects on proteinuria and early initiation of therapy may delay the progression to CKD in children with XLAS. There was no significant difference between the RAAS and RAAS+IS groups in kidney survival. AS patients presenting with NS or nephrotic range proteinuria should be followed up more carefully considering the risk of early progression to CKD.

Introduction: Autosomal recessive polycystic kidney disease (ARPKD) is associated with pathogenic variants in the PKHD1 gene. Autosomal dominant polycystic kidney disease (ADPKD) is mainly associated with pathogenic variants in PKD1 or PKD2. The present study aimed to identify the clinical and genetic features of Turkish pediatric ARPKD and ADPKD patients. Methods: This multicenter, retrospective cohort study included 21 genetically confirmed ARPKD and 48 genetically confirmed ADPKD patients from 7 pediatric nephrology centers. Demographic features, clinical, and laboratory findings at presentation and during 12-month intervals were recorded. Results: The median age of the ARPKD patients at diagnosis was lower than the median age of ADPKD patients (10.5 months [range: 0-15 years] vs. 5.2 years [range: 0.1-16 years], respectively, [p = 0.014]). At the time of diagnosis, the median eGFR in the ARPKD patients was lower compared to that of ADPKD patients (81.6 [IQR: 28.7-110.5] mL/min/1.73 m(2) and 118 [IQR: 91.2-139.8] mL/min/1.73 m(2), respectively, [p = 0.0001]). In total, 11 (52.4%) ARPKD patients had malnutrition; 7 (33.3%) patients had growth retardation at presentation; and 4 (19%) patients had both malnutrition and growth retardation. At diagnosis, 8 (16.7%) of the ADPKD patients had malnutrition, and 5 (10.4%) patients had growth retardation. The malnutrition, growth retardation, and hypertension rates at diagnosis were higher in the ARPKD patients than the ADPKD patients (p = 0.002, p = 0.02, and p = 0.0001, respectively). ARPKD patients with malnutrition and growth retardation had worse renal survival compared to the patients without (p = 0.03 and p = 0.01). Similarly, ADPKD patients with malnutrition had worse renal survival compared to the patients without (p = 0.002). ARPKD patients with truncating variants had poorer 3- and 6-year renal outcome than those carrying non-truncating variants (p = 0.017). Conclusion: Based on renal survival analysis, type of genetic variant, growth retardation, and/or malnutrition at presentation were observed to be factors associated with progression to chronic kidney disease (CKD). Differentiation of ARPKD and ADPKD, and identification of the predictors of the development of CKD are vital for optimal management of patients with ARPKD or ADPKD.

OBJECTIVES:Adult-onset Still's disease (AOSD) is a multi-systemic, autoinflammatory disorder. Several activity scores have been proposed but none of them have been adopted universally. Our aim was to create a clinician-friendly activity scoring system by using simple clinical and laboratory parameters. METHODS:AODS patients, according to Yamaguchi criteria, were included in this cross-sectional, multicenter study. Derivation and validation cohorts were constituted. Demographic, clinical, and laboratory evaluation at the study visit; patients' and physicians' global assessments of disease activity (both VAS/Likert scale) were recorded. To develop the score, an ordinal logistic regression model was used to determine independent predictors of physicians' global assessments of disease activity. Clinically and statistically significant variables were weighted according to regression coefficients. Then, performance of the score was tested on the validation cohort. RESULTS:A total of 197 consecutive AOSD patients (125 in derivation, 72 in validation cohorts) were included. Final Still Activity Score was fever (2 points), arthralgia (2 points, plus 1 point if arthritis was present in≥2 joints), neutrophilia≥65% (1 point) and ferritin≥350ng/mL (1 point) (maximum of 7 points). The SAS yielded an AUC value of 0.98 (0.96-1.00) in the derivation cohort and 0.91 (95%CI: 0.85-0.98) in the validation cohort to discriminate high AOSD activity from moderate-inactive AOSD. The correlation of SAS with PGA was 83% for the derivation cohort and 76% for the validation cohort. CONCLUSIONS:SAS has shown a good test performance to distinguish active AOSD patients from others. SAS may be a useful method for evaluating the disease activity of AOSD patients in daily practice.
