A Novel Experience in Treatment of Liver Hydatidosis in Pediatrics: A Clinical Trial Study

Background Hydatidosis is a conventional health public problem in most parts of the world. Safe treatment of patients with hydatidosis has been a topic of debate for a long time. Surgical treatment always was associated with high morbidity and mortality. Medical treatment is also controversial. In this study, alternative procedure named Percutaneous, Aspiration and hypertonic Saline Instillation (PAHSI) was applied to treat patients with hydatidosis. Materials and Methods In this single-blind clinical trial, thirty-eight patients, ranging in age between 6 months and 16 years, with 81 hepatic hydatid cysts underwent PAHSI treatment. The consecutive steps including sonographic guidance, aspiration of cyst content and injection of 15% saline hypertonic were carried out in this method. Patients with multiple cysts also were treated by this procedure. Results Participants were 18 boys (47.3%) and 20 girls (52.6%) with mean age of 8.08+ 3.92 years. Almost half of the patients had single cyst (52.63%). During 2- year follow- up, no recurrences were observed; therefore, re-hospitalization and possible complications reduced considerably. Furthermore, this method was applicable to cure multiple cysts. Conclusion In PAHSI strategy, it seems that the complications of surgery (laparotomy and anesthesia) decreased since no complications observed after procedure, and cosmetic results in future are much better due to avoidance of incision

Performance of reinforced concrete and timber structure at Kuala Muda Kedah during the tsunami

An earthquake at the Richter scale of 9.3 occurred near northwest coast of Aceh Indonesia underneath Indian Ocean in 2004. This earthquake triggered series of large tsunamis that killed around 250,000 people including 68 deaths in Malaysia. The most affected areas in Malaysia territory were the northern coastal region especially at Kuala Muda, Kedah. The major focus of this study is investigation of the effect of tsunami on performance of buildings subjected to alteration of shear forces and moments. Behavior of engineered (reinforced concrete structure) and non-engineered (timber structure) buildings subjected to tsunami-induced forces comprising hydrodynamic and debris impact is discussed both types of structures existed in the devastated area. Site investigation showed non-engineered structures especially low-rise timber ones suffer a greater degree of structural and non-structural damages. According to the fact that from all key parameters related to run-up of tsunami, only the parameters related to trees which can block the Tsunami waves, may be controlled. So, the best way to reduce the run up is planting trees according to the suitable methods especially in area that directly faces the sea

Bedside Teaching and Its Alternatives in the COVID-19 Pandemic

Background: Bedside teaching is a concentrated form of small-group teaching that takes place in the presence of the patient. Improvement in communication skills in a sympathetic manner with the patient and the ability to provide a purposeful history description and earning skills in clinical examinations is a goal that can only be achieved at the patient’s bedside. Bedside teaching has declined in recent years despite all its benefits; however, there are strong recommendations to continue this teaching modality for its valued benefits. In this context, we aimed to deal with the importance of bedside teaching and the challenges ahead in the covid epidemic as well as its alternatives for teaching medical students.  Evidence acquisition: This study was conducted through a literature search on articles in English with the relevant keywords (((((((“students, medical”[Mesh]) AND (“COVID-19”[Mesh])) AND (“education”[Mesh])) AND (“patient-centered care”[Mesh])) AND (“patient care team”[Mesh])) OR (“teaching rounds”[Mesh])) OR (“education, distance”[Mesh])) AND (“Physical examination”[Mesh]) using PubMed, Scopus, Web of Sciences, Cochrane, and Embase databases from 2001 to 2022. Results: In our search, 22 related articles were found, 3 of which were clinical trials) and 4 were review articles. This study summarized the following important issues related to bedside teaching: 1- We discussed the definition, importance, benefits, and difficulties of bedside teaching on the way to education; 2- We deliberated the causes of reluctance to carry out education at the bedside and the ways to deal with the reduction of its implementation; 3-we also noticed alternative methods for medical education in periods of special contact restrictions with patients such as the COVID-19 epidemic in this review. Conclusions: Bedside teaching has a fundamental role in medical education. In particular circumstances, such as covid 19 epidemy, in which the bedside teaching courses were suspended, it is necessary to allocate other educational arrangements and design a distance learning curriculum, including virtual teaching, uploading videos to view clinical procedures on social media platforms, interview with a virtual patient, and simulation

Preventable prenatal and neonatal risk factors of type 1 diabetes in childhood

Background: Childhood type 1 diabetes mellitus (T1DM) is an autoimmune disease which is increasing in incidence, but little is known about the events that trigger the autoimmune process. Most of the time, these processes begin in prenatal and natal periods; therefore, this study aimed to investigate the prenatal and neonatal risk factors of T1DM in childhood. Methods: This case-control study has been performed on children with T1DM who referred to the 17th Shahrivar children's hospital. The control group consisted of healthy siblings of the case group. Data were gathered using a form that included maternal and neonatal characteristics. Data were reported by descriptive statistics in SPSS 19. To investigate the effect of quantitative and qualitative variables on the development of T1DM, logistic regression and Chi-square tests were used, respectively. Results: Birth weight, birth height, and maternal weight gain during pregnancy had a significant relationship with T1DM (odds ratio [OR] = 1.23, 2.57, and 1.14, respectively). In addition, there was a significant relationship between gestational hypertension (OR = 5.27), neonatal jaundice (OR = 3.42), cesarean section (OR = 2.06), and being non–first-born child (OR = 2.32) and T1DM. Also, premature rupture of membrane, maternal urinary tract infection, and nonexclusive breastfeeding had a significant association with T1DM (OR = 4.37, 3.94, and 2.30, respectively). There were no statistically significant differences between maternal age, sex, neonatal respiratory disease, prematurity, and neonatal infections and T1DM (P > 0.05). Conclusions: Prenatal and neonatal risk factors can have a significant role in the occurrence of TIDM. Therefore, considering these risk factors can have a preventive effect on T1DM

Trait profiling and genotype selection in oilseed rape using genotype by trait and genotype by yield*trait approaches

Abstract Selection and breeding for high‐yielding in oilseed rape have always been one of the leading objectives for oilseed rape breeders. This process becomes more complicated when all quantitative traits are considered in selection in addition to grain yield. In the present study, 18 oilseed rape genotypes along with 2 check cultivars (RGS003 and Dalgan) were evaluated across 16 environments (a combination of 2 years and eight locations) in the tropical climate regions of Iran during 2018–2019 and 2019–2020 cropping seasons. The experiments were conducted in a format of randomized complete block design (RCBD) with three replications. The obtained multienvironmental trial data were utilized to conduct multivariate analysis, genotype by trait (GT) biplot, and genotype by yield*trait (GYT) biplot (Breeding, Genetics and Genomics, 1:2019). The GT and GYT biplot accounted for 55.5% and 93.6% of the total variation in the first two main components. Based on multivariate analysis and GT biplot, pod numbers in plant (PNP) and plant height (PH) were chosen as two key traits in spring oilseed rape genotypes for indirect selection due to high variation, strong positive correlation with grain yield (GY), and their high representatively and discriminability in genotype selection. The mean × stability GT biplot represented G10 (SRL‐96‐17) as the superior genotype. Based on the mean × stability GYT biplot, eight above‐average genotypes were identified that took high scores in stability, high‐yielding, and all evaluated quantitative traits at the same time. Based on the superiority index of GYT data, G10 (SRL‐96‐17) and G5 (SRL‐96‐11) indicated the best yield–trait combinations profile and ranked above check cultivars and then selected as superior genotypes. Similarly, cluster analysis using the WARD method also separated eight superior genotypes. Based on the result of the present study, GT ad GYT methodologies are recommended for trait profiling and genotype selection in oilseed rape breeding projects, respectively

The Iranian blood pressure measurement campaign, 2019: study protocol and preliminary results

Purpose Hypertension is one of the most important risk factors for premature mortality and morbidity in Iran. The objective of the Iranian blood pressure (BP) measurement campaign was to identify individuals with raised blood pressure and providing appropriate care and increase the awareness among the public and policymakers of the importance of tackling hypertension. Methods The campaign was conducted in two phases. The first (communication) phase started on May 17th (International Hypertension Day). The second phase started on June 8th, 2019, and lasted up to July 7th during which, blood pressures were measured. The target population was Iranians aged >= 30 years. Participants voluntarily referred to health houses in rural and health posts and comprehensive health centers in urban areas in the setting of the Primary Health Care network. Additionally, over 13,700 temporary stations were set up in highly visited places in urban areas. Volunteer healthcare staff interviewed the participants, measured their BP, and provided them with lifestyle advice and knowledge of the risks and consequences of high blood pressure. They referred participants to physicians in case their BP was high. Participants immediately received a text message containing the relevant advice based on their measured BP and their past history. Results Blood pressure was measured for a total of 26,678,394 participants in the campaign. A total of 13,722,148 participants (51.4%) were female. The mean age was 46 +/- 14.1 years. Among total participants, 15,012,693 adults (56.3%) with no past history of hypertension had normal BP, 7,959,288 participants had BP in the prehypertension range (29.8%), and finally, 3,706,413 participants (13.9%) had either past medical history of hypertension, used medications, or had high BP measured in the campaign. Conclusion The campaign was feasible with the objective to increase the awareness among the public and policymakers of the importance of tackling hypertension in Iran
