Background: Face masks have become an important tool for preventing the spread of respiratory diseases. However, we hypothesized that face masks with reduced nasal airflow may alter pulmonary artery systolic pressure (PASP).Purpose: This study aimed to evaluate the effect of face masks on PASP in children and adolescents.Methods: This case-control study was conducted between March 2021 and April 2022 at the Pediatric Cardiovascular Research Center in Isfahan, Iran. Using a convenience sampling method, a total of 120 children and adolescents, boys and girls aged 3–18 years, were allocated into 2 groups of 60 each (case group with congenital heart disease (CHD), control group of healthy subjects). For each patient in the case and control groups, echocardiography (ECHO), heart rate (HR), and blood oxygen saturation (SpO2) were performed and measured twice—once with a surgical mask and once without a surgical mask—by a pediatric cardiologist at 10-min intervals.Results: A total of 110 participants were analyzed. The mean patient age was 9.58±3.40 years versus 10.20±4.15 years in the case (n=50) and control (n=60) groups, respectively. Approximately 76.0% (n=38) of the participants in the case group versus 60.0% of those in the control group were male. In the case and control groups, there was a statistically significant reduction in the mean changes in tricuspid regurgitation (P=0.001), pulmonary regurgitation (P=0.002), and PASP (P=0.001) after face mask removal. Although this study showed a reduction in pulmonary arterial pressure after face mask removal in patients with CHD and healthy subjects, no significant changes in HR (P=0.535) or SpO2 (P=0.741) were observed in either group.Conclusion: Wearing a face mask increased PASP in healthy children and adolescents with CHD; however, the SPO2 and HR remained unchanged. Therefore, mask removal during ECHO is recommended.

[...]in order to make suitable planning for control of causative factors in these anomalies, it is necessary to conduct careful studies for identifying main risk factors in CHD. [...]the aim of this study was to investigate risk factors of CHDs in children in Isfahan, Iran. More mothers in case group had exposure to cigarette smoke during pregnancy (23.2% vs. 11.9%, P< 0.001) and teratogens including hair color (9.7% vs. 4.1%, P = 0.001), canned food (17.3% vs. 5.3%, P = 0.001), detergents (21.7% vs. 10.8%, P< 0.001), and using tobacco, alcohol, and opium (3.6% vs. 0.7%, P = 0.003) in the first trimester of pregnancy in both group. [...]results in this study showed that family history of CHD (P = 0.006), mother's diseases such as diabetes and hypothyroidism (P< 0.001), as well as the use of medications such as metformin and levothyroxine (P< 0.001) during pregnancy may have an effect on the occurrence of CHDs. [...]variables such as exposure to teratogens in the first trimester of the pregnancy (exposure to at least one of teratogens including hair color, canned foods, detergents, insecticide, alcohol, tobacco, and opium), use of mobile phone in pregnancy, family history of CHD, history of diseases in mother, and use of medicine during pregnancy were studied. According to the results

The increased prevalence of overweight and obesity in children and adolescents is associated with type 2 diabetes, hypertension, dyslipidemia, and cardiovascular diseases. The theory of planned behavior (TPB) efficiently explains the ability of perceived behavioral control and possibly attitude to enhance the motivations of the obese people to lose weight. Our aim was to investigate the effect of TPB-based education on weight loss in obese and overweight adolescents. In an interventional study, simple random sampling was used to select 86 overweight and obese adolescents aged 13-18 years in the pediatric clinic at the Isfahan Cardiovascular Research Institute. Anthropometric measures and TPB constructs were collected using a researcher-made questionnaire. The questionnaires were filled out before and six weeks after the intervention. Participants received 5 sessions of training based on the constructs of the TPB. A significant increase was observed in the mean score for knowledge and TPB constructs (attitudes, subjective norms, perceived behavioral control, intention, and behavior) six weeks after the educational intervention (P < 0.001). Moreover, significant decrease in body mass index (P < 0.001), weight (P = 0.001), and waist circumference (P < 0.001) of adolescents were found after the educational intervention. The TPB-based interventions seem to be effective in losing weight in obese and overweight adolescents. This theory serves as a helpful theoretical framework for health-related behaviors and can be an appropriate pattern to plan for educational interventions.

The aim of this study was to evaluate the effects of 8 weeks of aerobic training, resistance training (RT), combined training, and nutritional recommendations on lipid profile and body mass index (BMI) in obese and overweight children and adolescents. This randomized, clinical trial was conducted on 120 children and adolescents (10-19 years of age) with overweight and obesity. Participants were divided into 4 groups, the 3 intervention groups of high-intensity interval training (HIIT), RT, and combined training, and 1 non-exercising control group with healthy eating recommendations. We considered 24 sessions of training during 8 weeks for the intervention groups. The participants' anthropometric indices and lipid profile were assessed before and after the intervention. There were no significant differences between the groups in terms of anthropometric indices and lipid profiles before the intervention. After the intervention, there was a significant difference between the groups in terms of high-density lipoprotein (HDL) level; the control group (37.70 ± 9.45) and the HIIT group (43.65 ± 9.09) displayed the lowest and highest mean, respectively (P = 0.040). Comparison of physical variables and blood lipid profiles before and after the intervention showed a significant difference in waist circumference (P = 0.030), hip circumference (P ≤ 0.001), and HDL level (P = 0.040) in RT, HIIT, combined, and control groups. These results demonstrate that the combined training program and HIIT program with nutritional recommendations in overweight and obese children and adolescents were more effective in reducing BMI and hip circumference, respectively.

Background:In 2016, a prospective registry for pediatric patients with congenital heart disease (CHD) was established in Isfahan, Iran. Data on pediatric CHD in Iran are scant; accordingly, we aimed to report the early results of the Persian Registry Of cardioVascular diseasE (PROVE/CHD) Registry in Isfahan.Methods:All patients with CHD and associated defects diagnosed by pediatric cardiologists were assessed via echocardiography for inclusion in the present study between late 2016 and August 2019. The participants’ sociodemographic characteristics, maternal history, birth history, medical history, current clinical presentations in the clinic or hospital, paraclinical data, cardiac diagnoses based on the International Classification of Diseases, 10th Revision (ICD-10), disease management plans, and medications were entered into a questionnaire by the subjects’ parents/legal custodians and physicians and then transferred to the PROVE/CHD Registry.Results:The PROVE/CHD registry encompasses 1252 patients with CHD (49.9% male) at a mean age of 6.50±6.36 years. The most frequent cardiac diagnoses were ventricular septal defect (39.3%), atrial septal defect (29.7%), patent ductus arteriosus (25.4%), pulmonary stenosis (11.0%), tetralogy of Fallot (6.1%), coarctation of the aorta (5.4%), and aortic stenosis (5.1%), respectively. The most frequent interventions were patent ductus arteriosus closure (4.3%), atrial septal defect closure (3.6%), pulmonary valvuloplasty (2.2%), coarctation of the aorta angioplasty (1.9%), and ventricular septal defect closure (1.1%), correspondingly. The approximate corresponding rates of corrective and palliative surgeries were 32.0% and 13.1%. The corrective surgeries were mainly comprised of ventricular septal defect closure (7.8%), patent ductus arteriosus closure (7.3%), atrial septal defect closure (5.1%), and tetralogy of Fallot repair (3.8%), respectively. The palliative surgeries mainly consisted of the Glenn shunt (9.0%) and pulmonary artery banding (3.6%).Conclusion:The PROVE/CHD Registry collects data on pediatric patients with CHD. The results of this registry can provide epidemiological data and a set of homogeneously defined cases for further studies.

This research prioritization aimed to identify major research gaps in maternal, newborn, child and adolescent health (MNCAH) to help mitigate the direct and indirect effects of the COVID-19 pandemic. We adapted the Child Health and Nutrition Research Initiative methodology. We defined scope, domains, themes and scoring criteria. We approached diverse global experts via email to submit their research ideas in MNCAH and MNCAH-related cross-cutting/health systems area. We curated the research ideas as research questions (RQs) and sent them to the consenting experts for scoring via the online link. For each RQ, the research priority score (RPS) was calculated as an average of individual criterion scores and ranked based on RPS in each area. We identified top-ranked 10 RQs in each maternal, newborn, and child and adolescent health and 5 in the cross-cutting/health systems area. In maternal health, indirect effects on care, measures to improve care, health risks and outcomes, and preventing and managing SARS-CoV-2 infection/COVID-19 disease were priority RQs. In newborn health, clinical characterization and managing SARS-CoV-2 infection/COVID-19 disease, mode of transmission and interventions to prevent transmission were the focus. For child and adolescent health, top-ranked RQs were indirect effects on care, clinical status and outcomes, interventions to protect against SARS-CoV-2 infection/COVID-19 disease, and educational institute-related RQs. The cross-cutting RQs were the effects of the pandemic on availability, access, care-seeking and utilization of MNCAH services and potential solutions. We call on partners, including governments, non-governmental organizations, research institutes, and donors, to address this urgent research agenda.

Healthcare workers constitute a population at high risk for HBV infection. Efficient vaccination options are available; however, the individual response to HBV vaccination may vary widely between subjects, potentially due to cytokine profiles and genetic variations. In the present study, we investigated the relationship between IL-17 and IL-22 gene polymorphisms versus non- and low-responsiveness to HBV vaccination in healthcare workers. We selected the following IL-17 and IL-22 polymorphisms: rs4711998 (A/G) from IL-17 and rs2227501 (A/T), rs2227503 (A/G), rs1026786 (A/G) from IL-22 sequences genes. These were determined by polymerase chain reaction restriction fragment length polymorphisms. The IL-17 rs4711998 GG genotype had a significantly lower frequency in non-responders compared to low-responders (p=0.025). However, we did not identify a relationship between IL-22 rs1026780, rs2227501 and rs2227503 genotypes and the anti-HBs response following HBV vaccination. These data suggest that genetic variation in rs4711998 polymorphisms in the IL-17 cytokine may influence vaccine-induced immune responses to HBV vaccine in healthcare workers.
