Weight disorders, including underweight and overweight were defined according to the standardized National Center for Health Statistics (NCHS)/Centers for Disease Control (CDC) growth charts. Demographic data including gender, birth weight, maternal educational levels and occupation, duration of breastfeeding and the age of beginning complementary food were gathered.Results: In the present study, 750 children (i.e., 32.6%) had weight disorders. Among them, 53.6% were underweight, 26.3% were overweight, and 12.9% were obese, 7.2%had severe underweight. Female gender, university education of mothers and higher levels of socio-economic status significantly increased the chance of overweight by 14.79%, 22.28%, 27.33% and 24.48%, respectively. Although with the increase in the duration of breastfeeding and the increase of family members, overweight, respectively, decreased by 0.86 and 0.93 fold, but it was not statistically significant. There was an inverse, significant relationship between the duration of breastfeeding with overweight versus underweight.Conclusion: Underweight and overweight were the two most common weight disorders among 2-year- children, respectively.

Its effects are severe in adolescence and finding treatments with short therapy courses, superior results, and fewer adverse effects are of high importance. Materials and Methods: We included 30 individuals with acne vulgaris scars in Al-Zahra academic training hospital from June 2018 to Jan 2019. Each individual received both fractional CO2 and fractional Er:YAG lasers on right and left sides of the face, respectively. Three sessions of laser treatment were applied to each side with one-month intervals. Results were evaluated by patients according to subjective satisfaction and physicians’ assessment and photo evaluation by two blinded dermatologists. Improvement was graded by a quartile grading scale: less than 25%: mild, 25% to 50%: moderate, 51% to 75%: good, and 76% to 100%: excellent response. Assessments were obtained at baseline and one month after the last visit. Results: Based on subjective satisfaction (p < 0.05) and physicians’ assessment (p < 0.01), fractional CO2 laser was significantly more effective than Erbium:YAG laser. Also, Post-treatment side effects were mild and transient in both groups. Conclusion: Laser therapies are common in the treatment of scars and each modality has special advantages and disadvantages. Choosing among them should be based on various criteria. Fractional CO2 lasers have been revealed favorable results in most reports. Large comprehensive trials could help experts in choosing among alternatives for different subgroups.","PeriodicalId":7225,"journal":{"name":"Advanced Biomedical Research","volume":"12 ","pages":"90"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/34/e7/ABR-12-90.PMC10241645.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9599251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the present study aimed to determine the demographic characteristics and treatment follow-up of patients with spinal cord tumors. Materials and Methods: The present descriptive-analytical and cross-sectional study investigated all patients with spinal cord tumors in 2022 who visited the Kashani Hospital Isfahan. A total of 31 patients were included in the study using the census sampling method. The data were collected by a checklist and three pain scales, namely the Dennis pain scale, the Frankel Grade classification, and Nurick’s grading scales. Results: The present cross-sectional study examined 31 patients with spinal cord tumors who visited the Kashani Hospital in Isfahan. Most spinal cord tumors were ependymoma with nine cases (29%) and neurofibroma with six cases (19.35%). The tumor site was thoracic in 10 cases (33.33%). In the follow-up phase, 31 patients (53.4%) returned to their normal life with full recovery and 10 (17.2%) died. Three (75%) out of four cases of tumor recurrence had ependymoma tumors and one (25%) had astrocytoma. There was a significant difference between the patients’ pre- and post-operative pain severity and functional status as the post-operative scores decreased on all three scales. Conclusion: The results may contribute to improve the pre-operative planning, optimization, and monitoring of the patient’s recovery after the operation.","PeriodicalId":7225,"journal":{"name":"Advanced Biomedical Research","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135318132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irreparable damage to the mitral valve calls for its replacement using either a valve made up of biological tissue or metal, pyrolytic carbon, and similar materials. Materials and Methods: The material consists of 50 formalin-fixed adults, seemingly normal cadaveric hearts of either sex which were received from the Department of Anatomy of various institutes in the north region. These hearts were cut open to access the mitral valve in the left ventricle. Results: In this study, the posterior leaflet was semi-oval in shape being 3.72 cm wide at the base. Usually said to be tri-scalloped, interestingly, it was found so only in 56% of the hearts; being bi-scalloped in 20% and single-cusped in 16% of the hearts. Even four scallops and six scallops were observed in three (6%) and one (2%) hearts, respectively. Conclusions: To conclude, notable variation has been seen in the scallops of posterolateral cusps in the present study. The number of scallops varies greatly as single, double, three, four, or tetra-scalloped and most significant six or hexa-scalloped which has never been reported in the previous studies. To understand the rationale behind each unique architectural layout, such noticeable variations are crucial for scientists around the world.

While the utility of using model observers such as to optimize the clinical protocol is evident, the pitfalls associated with the use of this method in practice require investigation.Materials and methods: This study was performed using variable tube current and adaptive statistical iterative reconstruction (ASIR) level (ASIR 10% to ASIR 100%). Various criteria including noise, high-contrast spatial resolution, CHOs model were used to compare image quality at different captured levels. For the implementation of CHO, we first tuned the model in a restricted dataset and then it to the evaluation of a large dataset of images obtained with different reconstruction ASIR and filtered back projection (FBP) levels.Results: The results were promising in terms of CHO use for the stated purposes. Comparisons of the noise of reconstructed images with 30% ASIR and higher levels of noise in rebuilding images using the FBP approach showed a significant difference (P < 0.05). The spatial resolution obtained using various ASIR levels and tube currents were 0.8 pairs of lines per millimeter, which did not differ significantly from the FBP method (P > 0.05).Conclusions: Based on the results, using 80% ASIR can reduce the radiation dose on lungs, abdomen, and pelvis CT scans while maintaining image quality. Furthermore using ASIR 60% only for the reconstruction of lungs, abdomen, and pelvis images at standard radiation dose leads to optimal image quality.","PeriodicalId":7225,"journal":{"name":"Advanced Biomedical Research","volume":"12 ","pages":"8"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/c7/dc/ABR-12-8.PMC10012030.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9138624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Now, considering the effect of carvedilol on beta 1, 2, and alpha receptors and its antioxidant properties, it seems that it can prevent RV abnormalities. Therefore, the aim of this study was to investigate the possible protective effects of carvedilol in preventing RV dysfunction in patients with breast cancer treated with anthracyclines.Materials and methods: The present single-blind clinical trial study was performed on 23 patients with breast cancer that 12 of them received only the anthracycline antineoplastic doxorubicin (Adriamycin®) chemotherapy (control group) and 11 patients received carvedilol in addition to anthracycline. To evaluate the effect of carvedilol, patients underwent transthoracic echocardiography before intervention and 2 weeks after the end of treatment with anthracyclines.Results: The two parameters of RV ejection fraction and RV fractional area change in the carvedilol group with a mean of 66.41% ± 8.10% and 51.85% ± 6.89% were slightly higher than the control group with a mean of 64.58% ± 6.83% and 50.48 ± 5.79%, respectively, which was not statistically significant (P > 0.05).
