Abstract

Irritable Bowel Syndrome (IBS) is the most common functional gastrointestinal disorder and is a psychosomatic disorder. This study aimed to determine the effectiveness of Mindfulness-Based Cognitive Therapy (MBCT) on coping styles and gastrointestinal symptoms of IBS patients. This Experimental (pretest-posttest with the control group) study was conducted on 32 patients with IBS based on inclusion and exclusion criteria. They divided randomly assigned into two groups intervention (n = 15) and control (n = 17). ROME III was used for the diagnosis of IBS. coping styles were evaluated by using Lazarus coping styles questionnaire (CSQ). Data analysis was conducted in SPSS software by using student t-test, Mann-Whitney, and covariance. The results showed that the difference between the mean scores of coping styles (emotion-focused & problem-focused) and gastrointestinal  symptoms in the intervention group after the sessions of mindfulness-based cognitive therapy was statistically significant (p <0.01). The results show that mindfulness-based therapy can be effective in reducing and controlling psychological symptoms, enhance well-being and quality of life. Therefore, this therapy as an adjunctive therapy in patients with irritable bowel syndrome is recommended.

Abstract

Background and objective: Prevalence and the spread of novel Coronavirus (2019-ncov) cause significant life and financial destruction worldwide and is the cause of severe respiratory infection in humans. The present study briefly reviews the latest information on how the virus is distributed around the world. The main question of the study are: 1- In which geographic regions of the world is the Coronavirus more concentrated? 2- Is the distribution of the Coronavirus geographically stable?
Material and Methods: To answer these questions, we first began collecting and studying the available scientific resources. The required data was obtained from a daily report of confirmed, recovered, and deaths by the Coronavirus separated by state which was collected from January 22, 2020 to Jun 19, 2020. Based on analyzing available patterns in spatial statistics tool in ArcGIS and geostatistical models, we examined how the Coronavirus was distributed around the world.
Results: The spread of the disease is increasing all over the world. Using the results of Map 1, it is seen that the spread of Corona virus has a trend and starts in China and then spreads to the Middle East, Europe and the United States in a linear manner. The results also show that the prevalence of mortality is higher than that of recovery. Central mean and median for all types (Confirmed, Recovered and death) are close to each other. Death mean and median was close to Western countries and Recovered mean and median was close to Eastern countries, while confirmed mean and median was located in the center.
Conclusion: Based on spatial statistics tool in ArcGIS and geostatistical models, we examined how the Coronavirus was distributed around the world. Our results showed that the spread of Corona virus had a trend and started in China and then spread to the Middle East, Europe and the United States in a likely linear manner.

Abstract

Background and Objective: Human development is influenced by genetic, environmental, and social factors whose foundation is formed from infancy and childhood. Preterm birth and low birth weight are important issues that can affect the development and threaten the public health.
The aim of this study was to investigate the effect of early exercise interventions on gross motor skills of children with preterm birth aged 3 to 6 years.
Material and Methods: In this Experimental study, 30 children with average (2066 ±354g) were selected from among the preterm infants (32 to 37 weeks less than 2500 g) admitted to NICU ward. They were divided into two groups (experimental group n=15 and control group n=15 children).To evaluate the gross motor skills of children, the second version of the Peabody developmental motor scale was used. The results were analyzed by SPSS using ANCOVA test (p≤0.05).
ResultsThe results of this study showed that early interventions can have a positive effect on the gross motor skills of these children and the participants in the experimental group were able to obtain higher scores than the control group after participating in the training program.
Conclusion: The results showed that training interventions have a significant effect on both stability and locomotion skills.

Abstract

Background: In medical research and survival analysis, it is common for an individual or item's failure to be attributable to multiple causes, also known as competing risks. This article focuses on examining the competing risks model as the data increasingly becomes type II censored and randomly removed. The model assumes that the causes of failure are independent and that the lifetimes of individuals are described by the Cox model. At each failure time, the number of items or people removed follows a binomial distribution. The article derives estimators for the indefinite parameters in the model. The study presents a set of detailed data and includes a simulation study that also illustrates the results.
Methods: Different reasons, frequently known as competing risks, are frequently embroiled in an individual's or an item's failure in medical research survival analysis. The competing risks shown under sort II dynamic censoring with random removals are the subject of this research.
We get the maximum likelihood and inexact most extreme probability estimators of the obscure parameters. The asymptotic distribution of the maximum probability estimators is utilized to decide the CIs. Then, Monte Carlo simulations were applied to demonstrate the approach. The analyses were performed utilizing R 4.0.4 software.
Results: For stroke, systolic blood pressure (SBP) and hypertension status are the only significant variables. In contrast, gender, body mass index (BMI), smoking status, the logarithm of urinary albumin and creatinine ratio, and diabetes status are significant variables for coronary heart disease (CHD) and other cardiovascular diseases (CVDs). The results suggest that significant risk factors differ for different types of CVD events.
Conclusion: The outcomes of the simulation study indicate that progressively right-censored type II sampling designs outperformed the usual censored type II sampling designs. Therefore, the estimated parameters on the defined pattern setting are recommended. They can be used in many practical situations when competing risks occur, and progressive censoring could be considered.
