RESUMEN
BACKGROUND: The COVID-19 virus has had wide-ranging effects on all healthcare systems and a direct impact on all areas of human life in all countries around the world. Therefore, it is necessary to take preventive actions to reduce the prevalence and severity of the complications associated with this disease. The purpose of this study was to explain the dimensions of adopting general self-care behaviors (mask-wearing, social distancing, hand hygiene, and home quarantine) for preventing COVID-19 based on the theory of planned behavior (TPB) in cardiovascular patients. METHODS: This was a descriptive-analytical study conducted with the participation of 420 patients referring to health and treatment centers of Ahvaz, southwest of Iran, in 2022. Sampling was done using a non-random (convenience) method. The data collection tool was a questionnaire containing items addressing demographic characteristics, questions related to the TPB, and questions dealing with the adoption of everyday self-care behaviors against contracting COVID-19. Data were analyzed using descriptive and inferential statistical methods (prevalence, mean, standard deviation, Pearson's correlation coefficient, and linear regression) in SPSS version 25. RESULTS: The results of this study showed that the rate of adoption of self-care behaviors against COVID-19 among cardiovascular patients was moderate. The results also showed that among the constructs of the TPB, Perceived behavioral control, Subjective norms, and Perceived behavioral intention were the most important predictors of adopting self-care behaviors among cardiovascular patients with a change variance of 46%. CONCLUSIONS: The results of the present study have implications for health and treatment policy makers as well as planners of educational and behavioral interventions aimed at promoting the adoption of self-care behaviors against COVID-19. In this respect, managing and institutionalizing desirable behaviors among cardiovascular patients could be beneficial from economic, social, and health-related aspects.

AIM: This study aimed to compare the effectiveness of two visual pedagogy methods, video modeling and educational posters, on improving tooth-brushing autonomy in 10-12-year-old children with mild autism. METHODS: Sixty-four autistic children were randomly assigned to either the video or poster groups using the Rand function in Excel. Toothbrushing skills were divided into five stages: preparation, buccal, occlusal, lingual surfaces, and the end. These five stages comprised a total of 20 steps, with each step scored from 1 (not done at all) to 5 (done independently). The final score was calculated by averaging the scores of the five stages. The FONES method of toothbrushing was used for training. Follow-up assessments were conducted after 1 and 3 months. The data were analyzed using SPSS V26, including t-tests, Mann-Whitney U tests, and repeated-measures ANOVA. RESULTS: After 3 months, there were significant improvements in autonomy scores for both groups, with the video group showing greater benefits (4.37 ± 0.43) compared to the poster group (4.11 ± 0.49) (p = .03), with an effect size of η2 = .07. CONCLUSION: Both video and poster methods were effective in improving tooth-brushing skills, but video modeling was associated with a higher total autonomy score.
RESUMEN
OBJECTIVES: This study is designed in order to compare the efficacy and safety of recombinant human growth hormone (rhGH) with the reference brand. METHODS: According to the inclusion criteria, 85 people in 13 Iranian centers were randomly selected to receive biosimilar Somatropin (Somatin®) (44 people) and reference Somatropin (Norditropin®) (41 people) at a dose of 35 µg/kg/d, seven days/week for 12 months. The primary outcomes included height velocity (HV) was measured during 12 months of treatment. RESULTS: The two intervention groups' Height changes were similar. The mean HV was 10.96 cm/year in the biosimilar group and 10.05 cm/year in the reference groups after 12 months. Estimates of the lower bounds of 95% CI for mean height differences in the biosimilar intervention group compared to the reference intervention group did not exceed the 2 cm margin. Therefore, the non-inferiority of biosimilar intervention compared to the brand product is verified. Common ADRs in both groups were nausea in two patients (2.4%), diarrhea in two patients (2.4%), increased body temperature in one patient (1.2%), and headache in one patient (1.2%). CONCLUSIONS: The finding of this study indicated that Somatin® and Norditropin® have comparable efficacy and safety profiles. CLINICAL TRIAL REGISTRATION: www.IRCT.irIRCT20171122037571N1.
RESUMEN
BACKGROUND: Congenital hypothyroidism (CH) considered a common endocrine disorder in Iran. We report the epidemiologic findings of CH screening program in Isfahan, seven years after its development, regarding the prevalence of transient CH (TCH) and its screening properties comparing with permanent CH (PCH). MATERIALS AND METHODS: In this cross-sectional study, children with primary diagnosis of CH were studied. Considering screening and follow-up lab data and the decision of pediatric endocrinologists, the final diagnosis of TCH was determined. RESULTS: A total of 464,648 neonates were screened. The coverage percent of the CH screening and recall rate was 98.9 and 2.1%, respectively. Out of which, 1,990 neonates were diagnosed with primary CH. TCH was diagnosed in 1,580 neonates. The prevalence of TCH was 1 in 294 live births. 79.4% of patients with primary CH had TCH. Mean of screening (54.7 ± 59.0 in PCH vs 21.8 ± 28.9 in TCH), recall (56.5 ± 58.8 in PCH vs 36.6 ± 45.0 in TCH), and thyroid stimulating hormone (TSH) and mean of TSH before (2.0 ± 2.9 in PCH vs 1.6 ± 1.6 in TCH) and after (37.7 ± 29.5 in PCH vs 4.3 ± 1.9 in TCH) discontinuing treatment at 3 years of age was significantly higher in PCH than TCH (P < 0.0000). CONCLUSION: The higher rate of CH in Isfahan is mainly due to the transient form of the disease. Further studies for evaluating the role of other environmental, autoimmune and/or genetic factors in the pathophysiology of the disease is warranted.
RESUMEN
BACKGROUND: Antimicrobial photodynamic therapy (aPDT), is a promising approach proposed as an adjunct for the decontamination of dental implant surfaces. This study aimed to investigate the effect of aPDT with laser or light emitting diode (LED) compared with conventional chlorhexidine treatment on the titanium-attached biofilms of Aggregatibacter actinomycetemcomitans. METHODS AND MATERIALS: Thirty-six acid-etched and sandblasted (SLA) titanium discs were allocated to six groups and incubated with the titanium-adherent biofilms of A. actinomycetemcomitans as follows. Negative control (no treatment applied), positive control (0.2% chlorhexidine solution), 0.1 mg/mL Toluidine Blue [TBO] group, aPDT-treated groups subjected either to diode laser with a wavelength of 635 nm wavelength or LED with the peak wavelength of 630 nm with TBO as photosensitizer and sterile control (not contaminated). Following sonication and transferring the specimens to the microplate, the number of colony-forming units (CFUs) per disc was calculated. Data were analyzed using one-way analysis of variance (ANOVA) and additional post hoc tests with the level of significance set at P < 0.05. RESULTS: aPDT using TBO + LED was significantly more effective (0.93 ± 0.24 × 104) in the suppression of A. actinomycetemcomitans compared with TBO + Laser (2.65 ± 0.7 × 104). However, the lowest mean of CFU count was found in sterile, and chlorhexidine groups, respectively (P < 0.0001) and the highest bacterial count was observed in the negative control group (P < 0.0001). CONCLUSIONS: LEDs and diode lasers have a lower ability to suppress A. actinomycetemcomitans biofilms compared to 0.2% chlorhexidine in vitro. However, the aPDT with the use of LED as a light source and TBO as a photosensitive agent could be an appropriate alternative to conventional chlorhexidine treatment.

In this research, a new liquid phase microextraction based on the solidification of deep eutectic solvent (LPME-SDES) has been developed for the speciation of As(III), As(V), Se(IV), Se(VI), Hg(II) and organic mercury (R-Hg) in the blood of children prior to their analysis by iridium-modified tube electrothermal atomic absorption spectrometry (ETAAS). â¢In this method, a green solvent consisting of Choline chloride and decanoic acid in the molar ratio of 1:2 was used as a green hydrophobic deep eutectic solvent for the extraction of complexed ions from real blood samples.â¢The DESs replace the toxic organic solvents apply for extraction and could be synthesize from cheap accessible chemicals.â¢Under the optimum conditions, the calibration graphs for As, Se and Hg were linear in the rage of 0.15-40, 0.05-5.0 and 0.30-60 µg l-1, respectively and, the detection limit of As, Se and Hg were 0.05, 0.015 and 0.10 µg l-1, respectively.
RESUMEN
BACKGROUND: Considering the higher prevalence of congenital hypothyroidism (CH) in Iran and the importance of determination of the etiology of CH for assessing appropriate treatment strategies, understanding the pathogenesis of CH and the implications of its inheritance and prognosis, the aim of this study was to determine the etiology of CH 7 years after initiation of the program in Isfahan province. MATERIALS AND METHODS: In this cross-sectional study, children with a primary diagnosis of CH studied. They clinically examined and their medical files were reviewed by a Pediatric Endocrinologist. Considering screening and follow-up lab data and radiologic findings the etiology of CH was determined. Screening properties of different etiologies of CH was compared. RESULTS: In this study, 437 patients with permanent CH (PCH) were studied. Etiology of PCH in 316 (72.3%) and 121 (27.7%) of cases was thyroid dyshormonogenesis and thyroid dysgenesis, respectively. Prevalence of agenesis, ectopia, hypoplasia and hemiagenesis in thyroid dysgenetic patients was 13.3%, 6.4%, 4.3% and 3.7% respectively. Mean of thyroid stimulating hormone in screening, recall and after discontinuing treatment at 3 years of age was significantly lower in dyshormonogenetic CH patients than dysgenetic ones(P < 0.01). CONCLUSION: Seven years of our experiences in CH screening program indicated that the etiology of CH in Isfahan, with a higher rate of CH, with a predominance of thyroid dyshormonogenesis is different from most of the studies world-wide and similar to other reports from Iran. The findings of the current study provide us baseline information for determination of CH pathogenesis in this region.
RESUMEN
BACKGROUND: Considering the importance to determine the reasons for the higher occurrence of congenital hypothyroidism (CH) in Iran, in this study we report the prevalence of permanent CH (PCH) in Isfahan province 7 years after initiation of CH screening program in Isfahan. METHODS: In this cross-sectional study, children with a primary diagnosis of CH studied. They clinically examined and their medical files were reviewed by a pediatric endocrinologist. Considering screening and follow-up lab data, radiologic findings and the decision of pediatric endocrinologists the final diagnosis of PCH was determined. RESULTS: A total of 464,648 neonates screened in Isfahan province. The coverage percent of the CH screening and recall rate was 98.9% and 2.1%, respectively. A total of 1990 neonates were diagnosed with primary CH. PCH was diagnosed in 410 neonates. The prevalence of PCH and transient CH (TCH) was 1 in 1133 and 1 in 294 live births. The most common etiology of CH was thyroid dyshormonogenesis. CONCLUSIONS: Though the prevalence of PCH is high, but the higher prevalence of CH in Isfahan is commonly due to cases with TCH. Hence, the necessity of determining new strategies for earlier diagnosis of patients with TCH is recommended.
RESUMEN
Lipoid congenital adrenal hyperplasia (lipoid CAH), a rare disorder of steroid biosynthesis, is the most severe form of CAH. In this disorder the synthesis of glucocorticoids, mineralocorticoids and sex steroids is impaired which result in adrenal failure, severe salt wasting crisis and hyperpigmentation in phenotypical female infants irrespective of genetic sex. In this report, we presented a 28-day-old phenotypic female infant, which referred with lethargy, failure to thrive and electrolyte abnormalities. Considering the clinical and biochemical findings, lipoid CAH was diagnosed and replacement therapy with standard doses of glucocorticoid and mineralocorticoid and sodium chloride was initiated. During follow-up, she had good clinical condition, but at 6 years of age, she refers with hypertension and adrenal insufficiency because of arbitrary drug discontinuation by mother. In ultrasonography an abdominal mass (the testicles) was reported. Chromosome study showed 46XY pattern. Orchiectomy was performed. We recommended that in cases with clinical presentation of adrenal insufficiency if there is not the facility to determine the karyotype, repeated ultrasonography perform during follow-up. In addition, investigating the genetic bases of the disorder would help us to determine the pathogenesis of lipoid CAH in our community. It would be helpful in prenatal diagnosis and treatment of the disorder to prevent its related comorbidities.
