Life expectancy and the consequences of its impairment may affect quality of life and suicide. The aim of this study was to assess the impact of COVID-19 on life expectancy in residents of Gonabad city.

This cross-sectional study was conducted on 300 Gonabad residents (general population) from February 2021 to April 2022 using stratified-random sampling method. Data collection was performed through phone interview. Demographic questionnaire and Schneider's life expectancy scale were used. Data analysis was performed using the SPSS software version 23.

Of the 300 participants (53% female and 47% male), 153 were COVID-19 recovered and 147 did not have the history of COVID-19. The average life expectancy score in COVID-19 recovered participants was significantly lower compared to those without the history of COVID-19 (29.17 ± 5.96 and 31.94±4.34, respectively, p=0.001). Also, there was a significant and positive relationship between mean scores of life expectancy and age, gender, education, economic status, the presence of high-risk individuals at home, history of underlying diseases, and smoking (p<0.05).

The results of this study stated that life expectancy score in COVID-19 recovered participants was a lower than that of participants without COVID-19 history. Therefore, the role of other variables, including age, gender, and disease history on life expectancy was more prominent on life expectancy in COVID-19 recovered participants.

Regarding the advances in technology and anxieties around high and growing prices of fossil fuels, government incentives increase to produce cleaner and sustainable energy through distributed generations. This makes trends in the using microgrids which consist of electric demands and different distributed generations and energy storage systems. The optimum operation of microgrids with considering demand-side management increases efficiency and reliability and maximize the advantages of using distributed generations. In this paper, the optimal operation scheduling and unit commitment of generation units installed in a microgrid are investigated. The microgrid consists of technologies based on natural gas that are microturbine and phosphoric acid fuel cell and technologies based on renewable energy, including wind turbine and photovoltaic unit along with battery energy storage system and plug-in electric vehicle commercial parking lot. The goal of the paper is to solve a multi-objective problem of maximizing revenues of microgrid operator and minimizing emissions. This paper uses an augmented epsilon constraint method for solving the multi-objective problem in a stochastic framework and also implements a fuzzy-based decision-maker for choosing the suitable optimal solution amid Pareto front solutions. This new model implements the three type of the price-based and incentive-based demand response program. It also considers the generation reserve in order to enhance the flexibility of operations. The presented model is tested on a microgrid and the results demonstrate the efficacy of the proposed model economically and environmentally compared to other methods.</span></span></span></div>

Lack of donation is one of the major limitations of organ transplantation. Promoting organ donation requires increased awareness and creation of a positive attitude through training in specific ways. The purpose of this study was to compare the effect of peer-led education and education by healthcare personnel on awareness, attitude and performance of lettered people in regard with organ donation.

This case-control clinical trial was performed on 120 lettered people who were randomly assigned to three groups of 40, including peer-led, healthcare personnel and control groups. The two intervention groups underwent training sessions. Before and after the intervention, the data were collected and compared using questionnaires in three groups in three areas of awareness, attitude and performance.

Most of the lettered people (58.33%) were female. 61.66% had a bachelor's degree and 60.83% were teachers at elementary school. There was a significant difference in the mean scores of awareness, attitude and performance toward organ donation in the two intervention groups before the intervention (in peer-led group were 11.52 ± 2.12, 92.05 ± 10.24, and 1.87 ± 1.42 and in healthcare group were 11.30 ± 3.00, 90.73 ± 10.92, and 1.38 ± 1.29, respectively) and after the intervention (in peer-led group were 15.47 ± 1.13, 98.78 ± 5.70, and 3.53 ± 0.50 and in healthcare group were 15.13 ± 1.49, 96.95 ± 5.52, and 3.05 ± 0.81, respectively) ( P < 0.05). The mean score of attitude and performance of the lettered people in the peer-led group was significantly higher than the other groups (P < 0.05). 

The results of the study showed that peer-led education is a more effective method than education by healthcare personnel to promote and institutionalize organ donation.
 

Aims: Two major health problems in the developing countries are malnutrition and growth failure. The aim of this study was to investigate the growth indices (height and weight) and rate of growth failure in 1- to 18-mounth infants.
Instrument &

In the analytic-descriptive cross-sectional study, 1- to 18-mounth infants referred to the health centers of Quchan were studied in two steps in 2012. 1002 infants were selected via available method classified in three age groups. Heights and weights of the infants were recorded. Height and weight diagrams were described. Data was analyzed by SPSS 14 software.
Findings: Less than 5 percentile height and weight in 1- to 6-mounth infants, in 7- to 12-mounth infants, and in 13- to 18-mounth infants were 7.9 and 3.5% (in females) and 8.6 and 2.4% (in males), 5.3 and 9.3% (in females) and 8.1 and 7.0% (in males), 11.6 and 8.6% (in females) and 9.7 and 6.5% (in males), respectively. In growth failure, the most prevalent ages in males (9.7%) and in females (9.3%) were 13- to 18-mounth and 7- to 12-mounth, respectively. Maximum frequency of less than 5 percentile height was in 13- to 18-mounth infants (both genders).

Based on WHO criteria, nutritional status is favorable in 1- to 18-mounth infants in Quchan.

In this paper an approximate analytical solution of the fractional Zakharov-Kuznetsov equations will be obtained with the help of the reduced differential transform method (RDTM).It is in-dicated that the solutions obtained by the RDTM are reliable and present an effective method for strongly nonlinear fractional partial differential equations.

Abstract There are different attitudes about family presence during CPR. This study was conducted in order to compare the attitudes of physicians، nurses and patients` immediate family towards presence of family members during adult resuscitation in teaching hospitals of Mazandaran University of Medical Sciences. In this descriptive survey، the attitudes of 120 physicians، 200 nurses and 148 patients` immediate family were compared. Random stratified sampling was used as the sampling method. The data were collected using a self-developed questionnaire which its validity and reliability had been confirmed by “Content validity” and “Test-Retest” respectively (r=0/83). This questionnaire included some questions about demographic characteristics، positive and negative experiences and the attitudes towards family presence during CPR. Data were analyzed using Chi-square x2 and Fisher tests by the SPSS 16 software. The majority of physicians and nurses (92/5% physicians، 80%nurses) believed that family presence during CPR is harmful. Fisher exact test showed significant difference between physicians and nurses views (x2=9. 037 df=1 p value=0/002). The most important reason of negative attitudes of physicians and nurses has been interference of family members in CPR (90/8% physicians، 86/5% nurses). Less than half of the patients` immediate family (48%) wanted to be present during the CPR. There was a significant difference between attitudes of patients` immediate family and physicians and nurses (p=000) Regarding differences between physicians، nurses and patients` immediate family` attitudes towards family presence during CPR، it would be better to provide a determined plan identifying the family presence`s conditions during CPR in every hospital respectively.
