Examination of Physical Functions, Activity and Participation in Children with Juvenile Idiopathic Arthritis.

AIMS: To examine physical functions, activity, and participation level, and associated factors with participation in children with juvenile idiopathic arthritis (JIA) across the International Classification of Functioning Disability and Health-Children and Youth. METHODS: 49 children (Girl/Boy:28/21) aged between 7 and 18 years (Mean: 13.4 ± 3.3) were included. To evaluate body structure/functioning; pain, fatigue, disease activity, and motor functions were assessed. Childhood Health Assessment Questionnaire and Juvenile Arthritis Biopsychosocial and Clinical Questionnaire were used to determine activity level. Child and Adolescent Scale of Participation was used to assess participation. RESULTS: Mild level of pain (2.0 ± 2.3), disease activity (2.0 ± 2.3), and fatigue (4.1 ± 4.0) were recorded. Decrease in motor functions was determined in 75% of children, while 61% of whom had activity-related disability. There was mild to moderate participation restrictions, and participation was significantly associated with age (r = -0.29), pain severity (r = -0.31), disease activity (r = -0.39), motor functions (r = 0.33), and activity level (r = -0.43), (p Ë‚ 0.05). CONCLUSIONS: Majority of children with JIA have deteriorations in physical functions, activity, and participation. Age, pain, disease activity, motor functions and activity level were associated with participation level. Children with JIA should be regularly evaluated multi-directional and they should be referred to rehabilitation programs to increase functionality and participation.

Health Literacy Levels of Patients With Juvenile Idiopathic Arthritis and Their Parents.

BACKGROUND: The aim of this study was to reveal the relationship between the health literacy (HL) levels of children with juvenile idiopathic arthritis (JIA) and their parents, and the general health status and physical performance of the children. METHODS: This study included 79 children aged 9-18 years with a diagnosis of JIA and one of their parents. HL levels were evaluated with the Turkish version of the Health Literacy for School-Aged Children and Turkish Health Literacy-32 (THL-32) for children and Adult Health Literacy Scale (AHLS) for their parents. The Childhood Health Assessment Questionnaire (CHAQ), 6-minute walk test (6-MWT), 10-meter walking test (10-MWT) and 10-stair climbing test (10-SCT) was used to evaluate the children. Juvenile Arthritis Biopsychosocial Questionnaire (JAB-Q) was used to assess the children's and parents' psychosocial status and perception of health. RESULTS: HL levels of patients with JIA were 16.5% low HL, %55.7 moderate HL and 27.8% high HL. According to THL-32 scale score, HL level of parents were as follows: inadequate, 3.8%; problematic, 22.8%; sufficient, 34.2%; and excellent, 39.2%. Children's HL levels increase positively as they get older, and no significant relationship was found with other parameters. The AHLS, CHAQ and JAB-Q scores were better in the group with higher education levels of the parents. No statistically significant association was found between the HL of the children and that of the parents. CONCLUSION: In our study, it was found that the high education levels of the parents positively affected the quality of life and physical condition of their children and parental HL levels. In addition, it was shown that the HL levels of children with JIA were not statistically related to other parameters. PATIENT OR PUBLIC CONTRIBUTION: Children diagnosed with JIA and one of their parents actively participated in the study. Feedback from children and families provided important information about obtaining and using HL information before and during the study. The importance of therapy programs and information focusing on the patient and their family, as well as the inter-multidisciplinary approach, in combating a chronic disease at an early age was reinforced by the feedback received from patients and their families.

The Juvenile Arthritis Quality of Life Questionnaire in patients with juvenile idiopathic arthritis: Turkish version, validity, and reliability study.

INTRODUCTION: This study aimed to assess the cultural adaptation, validity, and reliability of the Turkish version of the Juvenile Arthritis Quality of Life Questionnaire (JAQQ) in patients with juvenile idiopathic arthritis (JIA). METHODS: A total of 100 JIA patients (64% female), aged 9 to 18 years, participated in the study conducted at a tertiary care university hospital. The JAQQ was culturally adapted through a rigorous translation process and administered alongside established measures, including the Childhood Health Assessment Questionnaire (CHAQ), Juvenile Arthritis Biopsychosocial Questionnaire (JABQ), and Children's Depression Inventory (CDI). Validity and reliability were evaluated using Spearman's correlation coefficients, Cronbach's alpha, intraclass correlation coefficient (ICC), standard error of the mean (SEM), and minimal detectable change (MDC). RESULTS: The Turkish version of JAQQ exhibited high convergent validity, correlating significantly with CHAQ, JABQ, and CDI. No floor or ceiling effects were observed in the total JAQQ score, indicating a balanced assessment. Internal consistency was excellent (Cronbach's α = 0.948), and test-retest reliability was satisfactory (ICC = 0.913). SEM and MDC95 values were 0.357 and 0.99, respectively. CONCLUSIONS: The Turkish adaptation of JAQQ emerges as a valid and reliable instrument for comprehensively assessing the health-related quality of life in children and adolescents diagnosed with JIA. The questionnaire's robust psychometric properties, coupled with distinctive features like individualized assessment, highlight its potential as a valuable tool for both clinical assessment and scientific research in the field of pediatric rheumatology. Key Points • The Juvenile Arthritis Quality of Life Questionnaire (JAQQ) is an important scale that evaluates the quality of life of children with Juvenile Idiopathic Arthritis (JIA). • JAQQ is known and used in the field of pediatric rheumatology in Turkey, but its Turkish adaptation has not been made before. • Our study includes 100 JIA patients aged between 9 and 18 years and shows that the Turkish version of JAQQ is valid and reliable in measuring the quality of life of these children. • This research contributes to the accurate assessment of the quality of life in Turkish children diagnosed with JIA, providing valuable insights for both clinical and scientific studies.

Myricetin May Improve Cardiac Dysfunction Possibly Through Regulating Blood Pressure and Cellular Stress Molecules in High-Fructose-Fed Rats.

BACKGROUND: The aim of this study was to examine the effect of myricetin on cardiac dysfunction caused by high fructose intake. METHODS: Fructose was given to the rats as a 20% solution in drinking water for 15 weeks. Myricetin was administered by oral gavage for the last 6 weeks. Systolic blood pressure was measured by tail-cuff method. The effects of isoprenaline, phenylephrine, and acetylcholine on cardiac contractility and rhythmicity were recorded in the isolated right atrium and left ventricular papillary muscles. In addition to biochemical measurements, the cardiac expressions of cellular stress-related proteins were determined by western blotting. RESULTS: Myricetin improved systolic blood pressure but did not affect body weight, plasma glucose, and triglyceride levels in fructose-fed rats. The impairment of isoprenaline- and phenylephrine-mediated increases in atrial contraction and sinus rate in fructose-fed rats was restored by myricetin treatment. Isoprenaline, phenylephrine, and acetylcholine-mediated papillary muscle contractions were not changed by fructose or myricetin administration. The expression of the mitochondrial fission marker dynamin-related protein 1 and the mitophagic marker PTEN-induced kinase 1 (PINK1) was enhanced in the fructose-fed rat, and myricetin treatment markedly attenuated PINK1 expression. High-fructose intake augmented phosphorylation of the proinflammatory molecule Nuclear factor kappa B (NF-κB) and the stress-regulated kinase JNK1, but myricetin only reduced NF-κB expression. Moreover, myricetin diminished the elevation in the expression of the pro-apoptotic Bax. CONCLUSION: Our results imply that myricetin has a protective role in cardiac irregularities induced by a high-fructose diet through reducing systolic blood pressure, improving cardiac adrenergic responses, suppressing PINK1, NF-κB, and Bax expression, and thus reflecting a potential therapeutic value.

Comparison of Biopsychosocial Characteristics of Children with Juvenile Idiopathic Arthritis According to Common Disease Subtypes.

OBJECTIVE: In this study, we assessed the functional and biopsychosocial characteristics of juvenile idiopathic arthritis (JIA) patients according to disease subtypes. MATERIALS AND METHODS: Child Health Assessment Questionnaire (CHAQ), Juvenile Arthritis Disease Activity Score-71 (JADAS-71), and Juvenile Arthritis Biopsychosocial Questionnaire (JAB-Q) scales were administered to 304 JIA patients, and the subscale of JAB-Q was administered to their families. RESULTS: The median age of JIA patients at diagnosis was 7.9 (5.5-13) years (female/male = 1.3). Most patients were under treatment (68.7%) and had inactive disease (69.3%). While there was no significant difference between JADAS-71 scores according to the JIA subtypes, total CHAQ scores in polyarticular JIA patients were higher than in systemic JIA patients (P = .005). Enthesitis-related arthritis (ERA) patients had higher JAB-Q fatigue total scores compared to systemic JJIA patients (P = .001). Juvenile Arthritis Biopsychosocial Questionnaire-child psychosocial status scores were higher in polyarticular JIA patients than oligoarticular and systemic JIA patients (P = .004 and P = .003, respectively), and they had higher JAB-Q child form total scores than systemic JIA patients (P = .006). In addition, systemic JIA patients' parents had higher JAB-Q family total scores compared to oligoarticular JIA patients' parents (P = .03). CONCLUSION: Our results suggest that polyarticular JIA patients had higher CHAQ, JAB-Q psychosocial status, and child form total scores, and the JAB-Q fatigue score was higher in ERA patients. Also, JAB-Q-parent scores were higher in systemic JIA patients' parents. Biopsychosocial characteristics should be evaluated in both JIA patients and their parents.

Development of a mobile monitoring program for anxiety and depression in pregnancy and evaluation of 3-month results.

BACKGROUND: The aims of this study were to develop a mobile mental health application (app) to scan the symptoms of anxiety, depression, and related factors during pregnancy; examine the effect of the app on pregnant women; and determine the factors related to using such an app. METHODS: A software platform called Perinatal Anxiety Depression Monitoring Platform (PADIP) was developed. This study included 320 pregnant women: 160 in the PADIP group and 160 in the control group. The PADIP group was screened monthly for 3 months for depression, anxiety, and sleep quality, and instant feedback was provided on scale scores. RESULTS: During the follow-up period, there was a significant decrease in depression and anxiety scale scores in the PADIP group but no significant difference in scale scores in the control group. The interface used for the app was important for scale scores. It was preferred by pregnant women with a high education level, higher Perinatal Anxiety Screening Scale scores, and lower sleep quality scores. CONCLUSIONS: PADIP use was associated with a decrease in depression and anxiety scores of pregnant women. It was more useful for patients with higher education levels and a history of a psychiatric disorder, but further research is needed to develop a more comprehensive model.

The Impact of the COVID-19 Pandemic on the Interest in Antidepressants: An Analysis of Worldwide Internet Searches With Google Trends Data.

OBJECTIVE: It is known that in the digital age we live in, people try to get information on many medical issues through Internet searches. Especially as a result of the COVID-19 pandemic triggering mental problems and health professionals' stay-at-home warnings, it has become difficult for individuals to receive psychiatric help, and this has encouraged accessing information about mental problems and their treatments through Internet searches. In this context, infodemiologic research, especially with Google Trends (GT; Google LLC, Mountain View, California, United States), has become very popular in recent years. In our study, it was aimed to examine the interest in frequently used antidepressants and the effect of the COVID-19 pandemic on Internet searches. METHODS: Search densities for five antidepressant drugs (sertraline, fluoxetine, citalopram, venlafaxine, duloxetine) that are frequently used around the world were examined on GT on 24/07/2023, and these searches were compared. Searches made within the last five years (24/07/2018-24/07/2023) were included in this study. Images were obtained using GT and Microsoft Excel 2019 (Microsoft Corporation, Redmond, Washington), and appropriate statistical analyses were performed with the SPSS Statistics version 22 (IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp.). RESULTS: Sertraline was the most sought-after antidepressant before, during, and after the COVID-19 pandemic in the world. The searches related to sertraline increased gradually during the pandemic period, and this increase continued in the post-pandemic period. Other antidepressants whose search for it increased with the pandemic are fluoxetine, duloxetine, and venlafaxine. Searches for citalopram decreased during the pandemic process compared to the pre-pandemic period. CONCLUSION: According to worldwide Internet searches, the prominence of some antidepressant group drugs during the pandemic period may be a reflection of the effects of the COVID-19 pandemic on mental health. Additionally, GT can provide psychiatrists with valuable insights into which depression medications are gaining popularity with the general public over time.

A new surgical path planning framework for neurosurgery.

BACKGROUND: Despite using a variety of path-finding algorithms that use tracts, the most significant advancement in this study is considering the values of all brain areas by doing atlas-based segmentation for a more precise search. Our motivation comes from the literature's shortcomings in designing and implementing path-planning methods. Since planning paths with curvatures is a complex problem that requires considering many surgical and physiological constraints, most path-planning strategies focus on straight paths. There is also a lack of studies that focus on the complete structure of the brain with the tracks, veins, and segmented areas. Instrument dependence is another inadequacy of the methods proposed in the literature. AIMS: The aim of this study is to design a new surgical path planning framework that helps to plan the surgical path independently of the instrument, considers the entire structure of the brain, and allows curvilinear surgical paths. Thus, neurosurgeons can generate patient-specific possible optimal surgical pathways before the neurosurgical procedure. MATERIALS & METHODS: The proposed framework includes different path-finding algorithms (Dijkstra, A*, and their aggressive variants) that find optimal paths by taking the risk scores (surgeons assessed all the segmented regions, considering the extent of damage. In this evaluation, scores ranged from "0 to 10," with the most critical areas receiving a score of "10," while the least possible affected areas were assigned a score of "0") for sensitive brain areas into consideration. For the tract image processing the framework includes fractional anisotropy (FA), relative anisotropy (RA), spherical measure (SM), and linear measure (LM) methods. RESULTS: This is the first paper to handle tracts and atlas-based segmentation of the human brain altogether under a framework for surgical path planning. The framework has a dynamic structure that gives the flexibility to add different path-finding algorithms and generate different widths of surgical pathways. Moreover, surgeons can update the score table to guarantee minimally invasive surgery. The output file format of all the extracted surgical paths is NRRD, so it can be easily visualised, analysed, or processed over the third part software tools. DISCUSSION: In this study, we generated many possible surgical pathways then these pathways were evaluated by the surgeons the results were impressive because the framework could identify surgical pathways used in real-world surgery that correspond to the standard pathways such as anterior transsylvian, trans sulcal, transgyral, and sub-temporal. CONCLUSION: This study proposes a new surgical path planning framework for neurosurgery. Moreover, in the future by adding/adopting different parameters (such as operation time, and short and long-term complications after surgery) to the proposed framework, it would be possible to find new surgical pathways for difficult surgical conditions.

The impact of dietary fructose on gut permeability, microbiota, abdominal adiposity, insulin signaling and reproductive function.

The excessive intake of fructose in the regular human diet could be related to global increases in metabolic disorders. Sugar-sweetened soft drinks, mostly consumed by children, adolescents, and young adults, are the main source of added fructose. Dietary high-fructose can increase intestinal permeability and circulatory endotoxin by changing the gut barrier function and microbial composition. Excess fructose transports to the liver and then triggers inflammation as well as de novo lipogenesis leading to hepatic steatosis. Fructose also induces fat deposition in adipose tissue by stimulating the expression of lipogenic genes, thus causing abdominal adiposity. Activation of the inflammatory pathway by fructose in target tissues is thought to contribute to the suppression of the insulin signaling pathway producing systemic insulin resistance. Moreover, there is some evidence that high intake of fructose negatively affects both male and female reproductive systems and may lead to infertility. This review addresses dietary high-fructose-induced deteriorations that are obvious, especially in gut permeability, microbiota, abdominal fat accumulation, insulin signaling, and reproductive function. The recognition of the detrimental effects of fructose and the development of relevant new public health policies are necessary in order to prevent diet-related metabolic disorders.

Detection of depression and anxiety in the perinatal period using Marine Predators Algorithm and kNN.

Undiagnosed prenatal anxiety and depression have the potential to worsen and have an adverse effect on both the mother and the infant. Although the diagnosis is made by specialist doctors, it is unclear which parameters are more effective. Especially in medicine, it is crucial to diagnose disease with high accuracy. For this reason, in this study, a questionnaire study was first conducted on pregnant women, and real original data were collected. Then, the Marine Predators Algorithm (MPA), one of the current metaheuristic algorithms inspired by nature, was combined with K-Nearest Neighbors (kNN) to determine high-priority features in the collected data. As a result, five of the 147 features selected by the proposed method were determined as high priority and approved by the doctors. In addition, the proposed method is compared with the Chi-square method, which is one of the filter-based feature selection methods. Thanks to the proposed feature selection method based on MPA and kNN, it has been observed that the classification gives more successful results in a shorter time with 98.11% success, and the model supports the diagnosis stage of the doctors.

The clinical phenotype of Koolen-de Vries syndrome in Turkish patients and literature review.

Koolen-de Vries syndrome (KdVS) is a rare multisystemic disorder caused by a microdeletion on chromosome 17q21.31 including KANSL1 gene or intragenic pathogenic variants in KANSL1 gene. Here, we describe the clinical and genetic spectrum of eight Turkish children with KdVS due to a de novo 17q21.31 deletion, and report on several rare/new conditions. Eight patients from unrelated families aged between 17 months and 19 years enrolled in this study. All patients evaluated by a clinical geneticist, and the clinical diagnosis were confirmed by molecular karyotyping. KdVS patients had some common distinctive facial features. All patients had neuromotor retardation, and speech and language delay. Epilepsy, structural brain anomalies, ocular, ectodermal, and musculoskeletal findings, and friendly personality were remarkable in more than half of the patients. Hypertension, hypothyroidism, celiac disease, and postaxial polydactyly were among the rare/new conditions. Our study contributes to the clinical spectrum of patients with KdVS, while also provide a review by comparing them with previous cohort studies.

Expanding the clinical and molecular features of trichorhino- phalangeal syndrome with a novel variant.

BACKGROUND: Tricho-rhino-phalangeal syndrome (TRPS) is a rare, autosomal dominant disorder characterized by typical craniofacial features, ectodermal and skeletal findings. TRPS type 1 (TRPS1) is caused by pathogenic variations in the TRPS1 gene, which relates to the vast majority of cases. TRPS type 2 (TRPS2) is a contiguous gene deletion syndrome involving loss of functional copies of the TRPS1, RAD21, and EXT1. Herein, we reported the clinical and genetic spectrum of seven TRPS patients with a novel variant. We also reviewed the musculoskeletal and radiological findings in the literature. METHODS: Seven Turkish patients (three female, four male) from five unrelated families aged between 7 to 48 years were evaluated. The clinical diagnosis was confirmed by either molecular karyotyping or TRPS1 sequencing analysis via next-generation sequencing. RESULTS: Both TRPS1 and TRPS2 patients had some common distinctive facial features and skeletal findings. All patients had a bulbous nose with hypoplastic alae nasi, brachydactyly, short metacarpals and phalanges in variable stages. Low bone mineral density (BMD) was identified in two TRPS2 family members presenting with bone fracture, and growth hormone deficiency was detected in two patients. Skeletal X-ray imaging revealed cone-shaped epiphysis of the phalanges in all, and multiple exostoses were present in three patients. Cerebral hamartoma, menometrorrhagia and long bone cysts were among the new/rare conditions. Three pathogenic variants in TRPS1 were identified in four patients from three families, including a frameshift (c.2445dup, p.Ser816GlufsTer28), one missense (c.2762G > A), and a novel splice site variant (c.2700+3A > G). We also reported a familial inheritance in TRPS2 which is known to be very rare. CONCLUSIONS: Our study contributes to the clinical and genetic spectrum of patients with TRPS while also providing a review by comparing with previous cohort studies.

Clinical features of generalized lipodystrophy in Turkey: A cohort analysis.

AIM: To describe the Turkish generalized lipodystrophy (GL) cohort with the frequency of each complication and the death rate during the period of the follow-up. METHODS: This study reports on 72 patients with GL (47 families) registered at different centres in Turkey that cover all regions of the country. The mean ± SD follow-up was 86 ± 78 months. RESULTS: The Kaplan-Meier estimate of the median time to diagnosis of diabetes and/or prediabetes was 16 years. Hyperglycaemia was not controlled in 37 of 45 patients (82.2%) with diabetes. Hypertriglyceridaemia developed in 65 patients (90.3%). The Kaplan-Meier estimate of the median time to diagnosis of hypertriglyceridaemia was 14 years. Hypertriglyceridaemia was severe (≥ 500 mg/dl) in 38 patients (52.8%). Seven (9.7%) patients suffered from pancreatitis. The Kaplan-Meier estimate of the median time to diagnosis of hepatic steatosis was 15 years. Liver disease progressed to cirrhosis in nine patients (12.5%). Liver disease was more severe in congenital lipodystrophy type 2 (CGL2). Proteinuric chronic kidney disease (CKD) developed in 32 patients (44.4%) and cardiac disease in 23 patients (31.9%). Kaplan-Meier estimates of the median time to diagnosis of CKD and cardiac disease were 25 and 45 years, respectively. Females appeared to have a more severe metabolic disease, with an earlier onset of metabolic abnormalities. Ten patients died during the follow-up period. Causes of death were end-stage renal disease, sepsis (because of recurrent intestinal perforations, coronavirus disease, diabetic foot infection and following coronary artery bypass graft surgery), myocardial infarction, heart failure because of dilated cardiomyopathy, stroke, liver complications and angiosarcoma. CONCLUSIONS: Standard treatment approaches have only a limited impact and do not prevent the development of severe metabolic abnormalities and early onset of organ complications in GL.

Effectiveness of a supervised group exercise therapy based on the biopsychosocial model introduced simultaneously with anti-TNF therapy in anti-TNF-naive patients with active ankylosing spondylitis.

BACKGROUND: This study aimed to investigate the effectiveness of a supervised group exercise therapy based on the biopsychosocial model introduced simultaneously with antitumor necrosis factor (TNF) therapy in anti-TNF-naive patients with active ankylosing spondylitis (AS). METHODS: Forty-eight patients were divided into two groups: the control group (CG; n = 36) received only anti-TNF therapy, and the study group (SG; n = 12) received the supervised exercise therapy based on the biopsychosocial model in addition to anti-TNF therapy. The measurements of disease activity and functionality were evaluated by The Bath AS Disease Activity Index (BASDAI) and The Bath AS Functional Index (BASFI) respectively. Other outcome measures evaluated biopsychosocial status, emotional state, spinal mobility, pain, fatigue, sleep, and quality of life. All measurements were applied to both groups at baseline and repeated 12 weeks later. RESULTS: BASDAI and BASFI analyses revealed significant differences between groups in favor of the SG (p < 0.05). At the end of the 12 weeks, the results showed that there were additional improvements in all outcome measurement parameters in the SG compared to the CG. DISCUSSION: The supervised group exercise therapy based on the biopsychosocial model introduced simultaneously with anti-TNF therapy is more effective than only anti-TNF therapy in anti-TNF-naive patients with active AS.

Responsiveness and Validity of Weight-Bearing Test for Measuring Loading Capacity in Patients With Triangular Fibrocartilage Complex Injury.

CONTEXT: Weight-bearing test (WBT) is a noninvasive quantitative test which has been used recently to determine loading capability of the individuals. The aim of this study was to strengthen the evidence for using the WBT test for measuring weight-bearing capacity of the upper-extremity with the specific objective of examining the internal and external responsiveness and concurrent validity of the test in patients with triangular fibrocartilage complex injury. DESIGN: Single-group repeated measures. METHODS: Internal responsiveness was assessed using effect size statistics. The correlation coefficient was used to examine external responsiveness by testing 5 hypotheses regarding predefined correlations between the changes in the measurements. Concurrent validity was evaluated by analyzing correlations between the WBT and other measurements. Thirty-one patients with triangular fibrocartilage complex injury were included for the analysis of the concurrent validity. Eighteen patients who completed all measurements at baseline and at 3-month follow-up enrolled for the responsiveness analysis. Measurements included the WBT, pain intensity, grip strength, and upper extremity functional level. RESULTS: The WBT test was able to detect statistically significant changes in weight-bearing capacity between baseline and follow-up (P = .0001). The effect size of the WBT was large. Three out of 5 hypotheses (60%) were confirmed, a good correlation was found between changes scores of the WBT and grip strength (r = .478; P < .05). There were significant correlations between the WBT and other measurements (r value range from -.401 to .742; P < .05). A higher correlation was found between the WBT and grip strength (r = .742; P = .0001). CONCLUSIONS: The responsiveness and concurrent validity of the WBT test confirmed that it is able to measure change in weight-bearing capacity in patients with triangular fibrocartilage complex injury.

Novel Gene Variants Associated with Primary Ciliary Dyskinesia.

OBJECTIVES: To determine the demographic, clinical, and genetic profile of Turkish Caucasian PCD cases. METHODS: Targeted next-generation sequencing (t-NGS) of 46 nuclear genes was performed in 21 unrelated PCD cases. Sanger sequencing confirmed of potentially disease-related variations, and genotype-phenotype correlations were evaluated. RESULTS: Disease-related variations were identified in eight different genes (CCDC39, CCDC40, CCDC151, DNAAF2, DNAAF4, DNAH11, HYDIN, RSPH4A) in 52.4% (11/21) of the cases. The frequency of variations for CCDC151, DNAH11, and DNAAF2 genes which were highly mutated genes in the cohort was 18% in 11 patients. Each of the remaining gene variations was detected once (9%) in different patients. The variants, p.R482fs*12 in CCDC151, p.E216* in DNAAF2, p.I317* in DNAAF4, p.L318P and p.R1865* in DNAH11, and p.N1505D and p.L1167P in HYDIN gene were identified as novel variations. Interestingly, varying phenotypic findings were identified even in patients with the same mutation, which once again confirmed that PCD has a high phenotypic heterogeneity and shows individual differences. CONCLUSION: This t-NGS panel is potentially helpful for exact and rapid identification of reported/novel PCD-disease-causing variants to establish the molecular diagnosis of ciliary diseases.

Evaluation of exonic copy numbers of SMN1 and SMN2 genes in SMA.

SMA is a neuromuscular disease and occurs primarily through autosomal recessive inheritance. Identification of deletions in the SMN1 gene especially in the exon 7 and exon 8 regions (hot spot), are used in carrier testing. The exact copy numbers of those exons in the SMN1 and SMN2 genes in 113 patients who presented with a pre-diagnosis of SMA were determined using MLPA method. We aimed to reveal both the most common copy number profiles of different SMA types. It was found that the frequency of homozygous deletions in SMN1 was 15.9%, while heterozygous deletions was 16.9%. The most common SMN-MLPA profile was 0-0-3-3. In the cases with homozygous deletion, SMA type III diagnosis was observed most frequently (44%), and the rate of consanguineous marriage was found 33%. Two cases with the same exonic copy number profile but with different clinical subtypes were identified in a family. We also detected distinct exonic deletion and duplication MLPA profiles for the first time. We created "the SMA signature" that can be added to patient reports. Furthermore, our data are important for revealing potential local profiles of SMA and describing the disease in genetic reports in a way that is clear and comprehensive.

Resveratrol and regular exercise may attenuate hypertension-induced cardiac dysfunction through modulation of cellular stress responses.

AIMS: Hypertension is one of the major causes of cardiac damage. In this study, the effects of resveratrol supplementation and regular exercise on hypertension-induced cellular stress responses of myocardium were compared. MAIN METHODS: Hypertension was induced in male Wistar rats by deoxycorticosterone-acetate + salt administration for 12 weeks. Resveratrol and regular exercise were applied for the last six weeks. In addition to biochemical and molecular examinations, isoprenaline, phenylephrine and, acetylcholine-mediated contractions and sinus rate were recorded in the isolated cardiac tissues. KEY FINDINGS: Resveratrol and regular exercise reduced systolic blood pressure in hypertensive rats. The altered adrenergic and cholinergic responses of the right atrium and left papillary muscles in hypertension were separately improved by resveratrol and regular exercise. Resveratrol and regular exercise decreased plasma and cardiac total antioxidant capacity and, augmented the expression of antioxidant genes in hypertensive rats. While regular exercise restored the increase in p-PERK expression associated with endoplasmic reticulum stress and decrease in mitophagic marker PINK1 expression, resveratrol only ameliorated PINK1 expression in hypertensive rats. Resveratrol and exercise training suppressed hypertension-induced NLRP3 inflammasome activation by reversing the increase in NLRP3, p-NF-κB expression and the mature-IL-1ß/pro-IL-1ß and cleaved-caspase-1/pro-caspase-1 ratio. Resveratrol and exercise enhanced mRNA expression of caspase-3, bax, and bcl-2 involved in the apoptotic pathway, but attenuated phosphorylation of stress-related mitogenic proteins p38 and JNK induced by hypertension. SIGNIFICANCE: Our study demonstrated the protective effect of resveratrol and exercise on hypertension-induced cardiac dysfunction by modulating cellular stress responses including oxidative stress, ER stress, mitophagy, NLRP3 inflammasome-mediated inflammation, and mitogenic activation.

Coexistence of a Homozygous Chromosome 4q35.2 Deletion and Hidden IQSEC2 Pathogenic Variant in a Child with Intellectual Disability.

Terminal deletions in the long arm of chromosome 4 are an uncommon event, with a worldwide incidence of approximately 0.001%. The majority of these deletions occur de novo. Terminal deletion cases are usually accompanied by clinical findings that include facial and cardiac anomalies, as well as intellectual disability. In this study, we describe the case of a 2-year-old girl, the fourth child born to consanguineous parents. While her karyotype was normal, a homozygous deletion was identified in the chromosome 4q35.2 region by subtelomeric FISH. A heterozygous deletion of the chromosome 4q35.2 region was observed in both parents. According to the literature, this is the first report of a case that has inherited a homozygous deletion of chromosome 4qter from carrier parents. Subsequent array-CGH analyses were performed on both the case and her parents. Whole-exome sequencing was also carried out to determine potential variants. We detected a NM_001111125.3:c.2329G>T (p.Glu777Ter) nonsense variant of the IQSEC2 gene in the girl, a variant that is related to X-linked intellectual disability.

Skeletal and molecular findings in 51 Cleidocranial dysplasia patients from Turkey.

Loss or decrease of function in runt-related transcription factor 2 encoded by RUNX2 is known to cause a rare autosomal-dominant skeletal disorder, cleidocranial dysplasia (CCD). Clinical spectrum and genetic findings in 51 CCD patients from 30 unrelated families are herein presented. In a majority of the patients, facial abnormalities, such as delayed fontanel closure (89%), parietal and frontal bossing (80%), metopic groove (77%), midface hypoplasia (94%), and abnormal mobility of shoulders (90%), were recorded following clinical examination. In approximately one-half of the subjects, wormian bone (51%), short stature (43%), bell-shaped thorax (42%), wide pubic symphysis (50%), hypoplastic iliac wing (59%), and chef's hat sign (44%) presented in available radiological examinations. Scoliosis was identified in 28% of the patients. Investigation of RUNX2 revealed small sequence alterations in 90% and gross deletions in 10% of the patients; collectively, 23 variants including 11 novel changes (c.29_30insT, c.203delAinsCG, c.423 + 2delT, c.443_454delTACCAGATGGGAinsG, c.505C > T, c.594_595delCTinsG, c.636_637insC, c.685 + 5G > A, c.1088G > T, c.1281delC, Exon 6-9 deletion) presented high allelic heterogeneity. Novel c.29_30insT is unique in affecting the P1-driven long isoform of RUNX2, which is expected to disrupt the N-terminal region of RUNX2; this was shown in two unrelated phenotypically discordant patients. The clinical findings highlighted mild intra-familial genotype-phenotype correlation in our CCD cohort.
