- چکیده:
- چکیده انگلیسی: The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and DNA pairing. Therefore, the amplification of hydrogen bonds strength by substituents may be important in life sciences. In the current research, we have shown that the nature of hydrogen bond in the enol form of heteroatom RAHB systems has partial covalent and electrostatic character. Nonetheless, the strength of hydrogen bonds increases by means of three different groups of substituents, which cannot be attributed to the contributions of resonance structures. Parameters such as bond ellipticity, p delocalization indices and bond equalizations cannot help to prove the effect of conjugation on the strength of hydrogen bond in RAHB systems. It is shown by NBO that the primary and secondary hyperconjugative charge transfer caused by substituents help to amplify this type of hydrogen bond. We showed that the existence of p-conjugation is necessary only for transformation of electron from substituents to the hydrogen bond as an acceptor of electrons.The strength of RAHB has a rather good correlation with the distance between of two non-connected heteroatoms O and N according to reference [62].

- چکیده:
- چکیده انگلیسی: Today technology is an integral part of professional translation; and it is generally assumed that translators’ attitudes toward translation technology tools influence their interaction with technology (Bundgaard, 2017). Therefore, the present two-phase study seeks to shed some light on what translation technology tools are and how professional translators feel toward them. The research method used is exploratory in nature, as it tends to discuss issues on which little research has been done and relies on secondary research for its data. The data required for answering the first question have been mined utilizing document analysis from language service providers’ (LSPs) websites, while the data for working out the answer to the second question have been obtained from ProZ.com Quick Polls. Based on our findings, translation technology tools fall into eight broad categories, of which the most commonly used are translation memory (TM) or computer-assisted translation (CAT) tools. In addition, it was found that most translators either do not have a love-hate relationship with technology or love it. This research is envisaged to form the basis of more detailed and conclusive studies.

- چکیده انگلیسی: Background
Coronavirus Disease-2019 (COVID-19) is a recently evolving public health problem. This study aimed to establish home care system for patients with acute respiratory infections in treatment centers and hospitals covered by Mashhad University of Medical Sciences, Mashhad, Iran.
Materials and Methods: In this pilot study, which was done as cross-sectional design from February 29, 2020 until May 4, 2020, all the patients with acute respiratory infections suspected of corona and referred to centers of health comprehensive services and outpatient clinics of Mashhad, Iran (referral level 1), were assessed based on protocol developed by Ministry of Health. Then, patients who do not need hospitalization services based on diagnosis of specialized health care team were referred home by prescription of medication and self-care training (home quarantine). Afterward, the required information based on care need, improving and thoroughly improved along with patient home visit and follow-up calling were implemented by physician. In the last phase, patients’ and their families’ satisfaction regarding health care team was assessed by a researcher-made questionnaire.
Results: In this pilot study, 200 patients (men: 62.9%) with Covid-19 underwent home quarantine and care and treatment by a specialized treatment team comprised of physician, nurses, and psychologist and health experts. The findings showed that 84.5% of patients and family had partial satisfaction regarding the way of treatment of the health care team. Satisfaction on explanations provided regarding disease, diagnosis, and treatment method in 68% of patients was full satisfaction.
Conclusion
Home quarantine decreases stress and fear in patients and their family and prevents social labelling for these individuals. Patients were highly satisfied regarding being cared for in their home and by family members.- انتشار مقاله: 27-09-1399

- چکیده:
- چکیده انگلیسی: Telemedicine is the use of telecommunication and information technologies in order to provide clinical health care at a distance. These technologies allow communications between patient and medical staff with convenience as well as the transmission of medical, imaging and health informatics data from one site to another. It is also used to save lives in critical care and emergency situations. Although telemedicine systems have many advantages, including the distribution of high quality medical services to remote areas, failure to comply with infrastructure will reduce the efficiency and quality of their services. Issues such as building the infrastructure of the medical information industry, including the legal infrastructure, and thus providing a suitable platform for the legal and ethical issues of Telemedicine, as well as obtaining the necessary permits and requirements, will play an important role in the successful implementation of a Telemedicine system. The purpose of this study was to become more familiar with the field of Telemedicine and its services, as well as to review some legal issues in the field of e-health. Telemedicine is not able to solve the problems of the health and social systems, but the problems of the health and social systems cannot be solved without Telemedicine.

- چکیده:
- چکیده انگلیسی: Background: Massage therapy has been commonly practiced as a traditional complementary therapy in neonates. This study was designed to evaluate the effects of massage on decreasing bilirubin levels in infants undergoing phototherapy.
Materials and Methods
A total of 60 term icteric infants without known risk factors who were admitted to the neonatal intensive care unit of Ghaem Hospital, Mashhad, Iran from 2016 to 2018 were involved in this preliminary clinical trial. The infant participants were randomly divided into the massage + phototherapy (intervention group, n=30) who received massage therapy (with field technique) thrice daily (every 8 hours) for 30 minutes each, and phototherapy alone (control group, n=30) who received phototherapy and routine care. Serum bilirubin samples were obtained at different time points in both groups.
Results: The mean feeding time in the intervention and control groups were 22.5 and 21.4 min, respectively. The mean birth weights in the intervention and control groups were 3052 and 3187 gr, respectively. No significant differences were found between the two groups in age, sex, Apgar score, maternal profile, and previous history of jaundice (P>0.05). Rates of bilirubin loss were 0.81±0.19 mg/dl/h and 0.59±0.18 mg/dl/h in the intervention and control groups, respectively (P=0.043), in the first 8 hours of admission which dropped to 0.46±0.16 and 0.37±0.22, respectively (P=0.958), in the first 30 hours of admission.
Conclusion
Based on the results, massage is suggested as a complementary method for phototherapy, especially in the first eight hours of treatment during toxic high bilirubin levels and at the peak risk of kernicterus.- انتشار مقاله: 23-03-1398

- چکیده انگلیسی: Background: Asthma is a growing problem worldwide and the limitations of the current therapy for allergic asthma highlight the need for novel therapeutics. We conducted a systematic review and meta-analysis to find out the role of probiotics in the treatment of Asthma.
Materials and Methods: In this systematic review, a comprehensive search of the major electronic databases was done till October 2017. Clinical trials comparing the effect of probiotics versus placebo on treating asthma were included. Trials focusing on prevention of asthma were not included. A predefined set of outcome measures was assessed. Continuous data were expressed as standardized mean difference with 95% confidence interval (CI). Dichotomous data were expressed as odds ratio with 95% CI. P-value < 0.05 was considered as significant.
Results: 11 studies with 2,027 participants were included. Probiotic intake was associated with a significant improvement in pulmonary function test and slight benefits in asthma control test. Probiotics did not reduce asthma exacerbation and wheezing episodes although there was a high degree of heterogeneity in studies. It also has no significant effect on viral respiratory infection in asthmatics and no improvement in quality of life. Probiotic intake improved the following parameters: longer time free from episodes of asthma. Adverse events were not significant.
Conclusion: Although trials showed promising effects of probiotics as an additive on therapy on some parameters of asthma, as this evidence was generated from only a few trials with high degree of heterogeneity, routine use of probiotics as an additive on therapy of asthmatic patients cannot be recommended at this time.- انتشار مقاله: 14-09-1397

- چکیده:
- چکیده انگلیسی: Epilepsy is a brain disorder in which a person has repeated seizures over time. A seizure is a sudden change in the electrical and chemical activity in the brain. A single seizure that does not happen again is NOT epilepsy. Most children with epilepsy live a normal life. Certain types of childhood epilepsy go away or improve with age, usually in the late teens or 20s. Nearly 80% of people with epilepsy live in low- and middle-income countries. The risk of premature death in people with epilepsy is up to three times higher than for the general population. There is no known way to prevent epilepsy. Proper diet and sleep may decrease the chances of seizures in children with epilepsy. Reduce the risk of head injury during risky activities. This can decrease the likelihood of a brain injury that leads to seizures and epilepsy. Treatment for epilepsy includes: Medicines, Lifestyle changes and Surgery. Three quarters of people with epilepsy living in low-income countries do not get the treatment they need.

- چکیده:
- چکیده انگلیسی: Introduction: Feedback is a conscious, unbiased, and objective evaluation of performance in order to improve clinical skills, not to assess students' personal talents and values. This study aims to compare the views of pediatric residents and general medical students at Mashhad University of Medical Sciences regarding method of providing feedback in clinical education.
Method: This cross-sectional study was conducted in the pediatric ward of hospitals affiliated to Mashhad University of Medical Sciences in 2018. The census method was used to select 35 pediatric residents and simple random sampling method was used to select 35 general medical students who had completed internship and apprenticeship. Data collection was carried out using a standard 21-item feedback questionnaire. Pediatric residents and general medical students were asked to identify the importance of feedback received during their clinical education using a 4-point Likert scale.
Results: The majority of residents believe that feedback was only sometimes expected (27.1%), clearly and explicitly outlined (17.1%), fair (21.4%), and useful in correcting their attitude (18.6%), performance (17.1%), and behavior (27.1%). Majority of general medical students believed that clear, explicit (24.3%) feedback was related with their future career (14.3%) and most of them received positive feedbacks (20). Apart from propositions items 20, 18, and 17, most medical students and residents have selected the Often and Sometimes options, respectively to respond to items.
Conclusion: Pediatric residents were less satisfied with the feedback received during the clinical education as compared to the general medical students.- انتشار مقاله: 07-05-1398

- چکیده:
- چکیده انگلیسی: Every year, some 3.9 million girls aged 15 to 19 years undergo unsafe abortions (1). Approximately 16 million girls aged 15 to 19 years and 2.5 million girls under 16 years give birth each year in developing regions (2, 3). Complications during pregnancy and childbirth are the leading cause of death for 15 to 19 year-old girls globally (4). Adolescent mothers (ages 10 to 19 years) face higher risks of eclampsia, puerperal endometritis, and systemic infections than women aged 20 to 24 years (5, 6).
The term "adolescent" is often used synonymously with "teenager". In this sense "adolescent pregnancy" means pregnancy in a woman aged 10–19 years (2, 7). Pregnant teenagers face many of the same pregnancy related issues as other women. There are additional concerns for those under the age of 15 as they are less likely to be physically developed to sustain a healthy pregnancy or to give birth (8). For girls aged 15–19, risks are associated more with socioeconomic factors than with the biological effects of age (9). Risks of low birth weight, premature labor, anemia, and pre-eclampsia are connected to biological age, being observed in teen births even after controlling for other risk factors (such as accessing prenatal care etc.) (5, 6).- انتشار مقاله: 10-03-1398

- چکیده:
- چکیده انگلیسی: Background: Mothers and infants are considered as two vulnerable groups. Most problems occur during and immediately after delivery, which, if not addressed promptly, lead to death of mother, baby, or both. Maternal emotional support and midwifery care is one of non-pharmacologic methods of pain management during labor and delivery. Since the quality of midwifery care has an effective role in mothers' satisfaction with midwife's performance, this study was conducted to assess the quality of mothers' satisfaction with midwifery care.
Materials and Methods
In this cross-sectional study, 400 mothers admitted to the postpartum ward of Shahid Mobini Brothers Hospital of Sabzevar, Iran, were evaluated by simple convenience sampling. The research instrument was a questionnaire entitled "Satisfaction with quality of midwifery care in labor and delivery room", and was confirmed by content validity method and reliability was calculated by Cronbach's alpha coefficient (α = 0.92). Data were analyzed using SPSS software version 16.0.
Results: The average age of mothers was 25.88 ± 5.70 years old. The mean maternal satisfaction was 104.72 ± 0.76. In satisfaction category, 1% were dissatisfied, 17.3% had moderate satisfaction, and 81.7% had high level of satisfaction. There was a significant relationship between the variables affecting the level of satisfaction including education, age, and number of maternal deliveries with satisfaction (P<0.05).
Conclusion
The results of this study indicate that mothers have high satisfaction with the quality of midwifery care in the maternity ward. This care is mainly performed by midwives, and midwifery tutors and students. Therefore, it is recommended to apply midwives in other areas requiring specialized midwifery performance.- انتشار مقاله: 08-11-1397
