Materials and Methods: In this clinical trial study, 44 patients were randomly assigned to an exercise-medication treatment group (24 individuals) and a laser-exercise-medication treatment group (20 individuals). Symptoms were assessed based on Visual Analogue Scale (VAS), Neck Disability Index (NDI), and Shoulder Pain and Disability Index (SPDI) in three stages including before treatment, subsequently after treatment and one month after treatment. Independent t-test and repeated measures ANOVA were used to analyze the statistical data. Results: A significant difference was found among the studied groups before and after starting treatment for VAS, NDI and SPDI indices (p<0.001). However, laser therapy provided a higher effect on VAS in comparison with the control group subsequently after treatment (p=0.032). Nevertheless, evaluation after one month from treatment did not show a significant difference in the 2 treatment methods for the three indices (p>0.05). Conclusion: According to the results, exercise-medication therapy and laser-exercise-medication therapy may result in similar effects for relieving pain and eliminating symptoms in patients with myofascial pain syndrome in long-term, but subsequently after treatment, laser-exercise-medication therapy provides a higher effect on VAS.

This study aimed to investigate the association between leisure time variables, including television and computer using time, homework time and cell phone using time, with children’s school performance in a nationally representative sample of Iranian children and adolescents. Materials and Methods: In this analytical cross-sectional study as the fifth survey of a national school-based surveillance program in Iran, participants were selected by multi-stage sampling approach among 7-18-year-old students from urban and rural areas. In addition to filling questionnaires obtained from World Health Organization Global School Health Survey and conducting physical examinations, the averages of school grades were categorized into "very good" (grade 17-20 out of 20), and "not very good" (under 17 out of 20) as school performance according to qualitative evaluation scales established recently in Iranian schools. Results: The participation rate was 99%, 14,274 students completed the study. Urban students spent more time doing homework and using screen media, and they had better school performance than rural students (P < 0.001). Girls had higher homework time and better school performance than boys (P < 0.001). Prolongedscreen time, including watchingtelevision and computer use increased the odds of lower school performance (Odds ratio = 1.11). No other media type times or homework time had a significant association with school performance. Conclusion: In this study, prolongedscreen time represents an inverse association with school performance. Television viewing time, computer and cell phone using time and homework time might have no separate significant effects on school performance.

Method: Study Identification was carried out in databases (PubMed, Embase and Cochrane Library) to identify published studies examining the diagnosis, the 2019 novel coronavirus (2019-nCoV). Heterogeneity among reported prevalence was assessed by computing p-values of Cochrane Q-test and I 2-statics. The pooled prevalence of treatment failure was carried out with a fixed effects meta-analysis model, generating the pooled 95% confidence interval. A random-effect model was used to pool the results since this model could incorporate the heterogeneity of the studies and therefore proved a more generalized result. Results: According to the combined results of meta-analysis, the total 55% of corona patients were males. The mean age of the patients was 41.31 (34.14, 48.47). Two prevalent clinical symptoms between patients were fever, cough with prevalence of 85%, and 62%, respectively. Either Ground Glass Opacity GGO or consolidation was seen in 86% but 14% had NO GGO or consolidation. The other rare CT symptoms were pericardial effusion, and pleural effusion with 4, 5, 7% prevalence, respectively. The most prevalent event was Either GGO or consolidation in 85% of patients. Conclusion: The most CT-scan abnormality is Either Ground Glass Opacity GGO or consolidation however in few patients none of them might be observed, so trusting in just CT findings will lead to miss some patients.

Data were obtained from the fifth survey of a national school-based surveillance program in Iran. Sunlight exposure time, sleep duration, sleep onset time, physical activity time, mental health status and frequency of consuming coffee and tea were recorded. Overall, 14 274 students aged 7-18 years were recruited. Sleep duration was associated positively with sex, age, body mass index and physical activity, as well as with sunlight exposure and negatively with the consumption of coffee and tea. Higher physical activity, exposure to sunlight and mental status score in children exposed to sunlight via their face, hands, arms and feet, reduced the likelihood of sleep onset time after midnight (odds ratio (OR) ¼ 0.909, 0.741 and 0.554 respectively). Daily exposure to sunlight may increase sleep duration and advance the sleep onset time in children and adolescents.

We aimed to investigate the correlation of sedentary behavior and its indicators with low back pain (LBP) among adults and children. Methods: Original articles published up to April 28, 2020, using PubMed, Embase, Web of Science and Scopus were evaluated. Odds ratio (OR, 95% CI) was considered the overall effect size for desired associations. Results: We reviewed 49 English articles with analytical observational study design, of which, 27 studies with cross sectional/survey design were retained in the meta-analysis. Among adults, sedentary lifestyle was a considerable risk factor for LBP (OR = 1.24, 1.02-1.5); prolonged sitting time (OR = 1.42, 1.09-1.85) and driving time (OR = 2.03, 1.22-3.36) were the significant risk factors. Sedentary behavior was associated with LBP in office workers (OR = 1.23). Moreover, excess weight (OR = 1.35, 1.14-1.59) and smoking (OR = 1.28, 1.03-1.60) were associated with LBP. Among children, sedentary lifestyle was a remarkable risk factor for LBP (OR = 1.41, 1.24-1.60); prolonged TV watching (OR = 1.23, 1.08-1.41) and computer/mobile using and console playing time (OR = 1.63, 1.36-1.95) were significant risk factors for LBP. Consumption of coffee, however, has yield conflicting results to be considered as a risk factor. Moreover, the researches on the correlation between sedentariness and high-intensity LBP are scarce and inconclusive. Conclusion: Sedentary behavior, whether in work or leisure time, associates with a moderate increase in the risk of LBP in adults, children and adolescents.

The current review examined the differences in offspring's bone mineral density (BMD) between mothers smoked during pregnancy and those who did not. A systematic review and meta-analysis on the studies investigating the influence of maternal smoking during pregnancy on children or neonates' bone measures published up to October 30, 2018, was performed. BMD results measured at different body sites were pooled and then fixed or random effect models were used based on the presence of heterogeneity. The desired pooled effect size was the offspring's BMD mean difference with 95% confidence interval between smoker and non-smoker mothers. Sensitivity analysis was performed for birth weight and current weight, two important mediator/confounders causing heterogeneity. Overall, eight studies consisting of 17,931 participants aged from infancy to 18 years were included. According to the fixed effect model, the mean of BMD in offspring whose mothers smoked during pregnancy was 0.01 g/cm 2 lower than those with non-smoker mothers (95% CI = − 0.02 to − 0.002). However, subgroup meta-analysis adjusted for birth weight and current weight demonstrated no significant mean difference between BMD of children with smoker and non-smoker mothers (d = 0.06, 95% CI = −0.04 to 0.16, p value = 0.25 and d = − 0.005, 95% CI = − 0.01 to 0.004, p value = 0.28, respectively). According to available studies, it is suggested that maternal smoking during pregnancy does not have direct effect on the offspring's BMD. Instead, this association might be confounded by other factors such as placental weight, birth weight, and current body size of children.

Impaired sleep can be one of these environmental factors through alterations in immune functions. [3,4] Previous studies reported impaired sleep in IBD patients. These patients had significantly prolonged sleep latency, frequent sleep disruption, higher consumption of sleeping medications, daytime fatigue, and poor overall sleep quality compared to healthy controls. Poor sleep quality is prevalent even in inactive IBD patients. [5] Patients in clinical remission with abnormal sleep have a high likelihood of subclinical disease activity (i.e., histologic evidence of inflammation). [3] Furthermore, sleep disturbances are associated with more disease flares.

Considering different interventions which are applied for patients with plantar fasciitis, dry needling is proposed as a new modality of treatment recently. The aim of this study is to evaluate the effectiveness of dry needling versus steroid injection for plantar fasciitis. Methods Sixty-six patients were recruited to this singleblind clinical trial study. Participants were randomly allocated to receive 1 ml (40 mg) of Depo-Medrol (methylprednisolone acetate) or dry needling. They were followed up for 12 months and monitored for total perception of pain using the visual analogue scale (VAS), with data obtained in baseline and at three weeks, six weeks, three months, six months and one year after treatment. Results Mean VAS score before treatment was 6.96 ± 0.87 for the steroid group and 6.41 ± 0.83 for the dry-needling group (P value = 0.54). Steroid injection reduced VAS scores rapidly until three weeks after treatment compared with dry needling (0.32 ± 0.71 and 3.47 ± 1.32, respectively; P value < 0.001). However, patients who were underwent dry needling reported lower VAS scores at the end of follow-up compared with the steroid group (0.69 ± 0.93 and 2.09 ± 1.58, respectively; P value = 0.004). Over the long term, 82.3% and 17.6% of changes in pain were contributed to time since treatment and treatment method, respectively (P values < 0.001). Conclusions Steroid injection can palliate plantar heel pain rapidly but dry needling can provide more satisfactory results for patients with plantar fasciitis in the long term.

Herpes zoster is an infectious disease with neurological complications caused by reactivation of ... more Herpes zoster is an infectious disease with neurological complications caused by reactivation of varicella zoster virus in dorsal root ganglia of spinal cord which is also known as "Shingles." Suppression of immune system is the major predisposing factor for reactivation of latent virus. Disease is mainly characterized by rash, vesicles and pain along one or more dermatomes which are innervated from one or more spinal nerve roots. Complications may be present after a while despite of patient treatment. Motor involvement is included. Some previous studies showed segmental zoster paresis as a rare complication, a few weeks after first presentation, among immunocompetent individuals. We present post herpetic motor involvement of C5 and C6 in a 59-year-old woman who underwent chemotherapy and radiotherapy due to breast cancer, manifesting left upper limb weakness and paresis, 6 months after left partial mastectomy. Segmental paresis of zoster virus should be considered as a cause of motor impairment in an immunocompromised person suffering from shingles.

Although life expectancy of IBD patients is near to the mean of healthy population, IBD basically damages HRQOL. Chronic nature of disease, frequent recurrence of symptoms, extraintestinal manifestations, the effect of medical and surgical treatments and their side effects, stress of developing cancer, and needing surgery have impacts on daily lives of patients and cause significant reduction in quality of life (QOL). It seems that the most important factor which affects HRQOL in IBD patients is presence or absence of inflammatory activity although the impact of other sociodemographic factors should be considered. Nevertheless, physical symptoms of IBD do not explain decrements in HRQOL completely. [2] Moreover, some investigators have shown that disease characteristics including endoscopic activity index and disease activity index are associated with HRQOL, but Background: Inflammatory bowel disease (IBD) has a significant impact on health-related quality of life (HRQOL). This study aims to investigate the variables which can be attributed to HRQOL in IBD patients. Materials and Methods: Seventy-one patients filled in IBD questionnaire (IBDQ-32), Pittsburgh sleep quality index questionnaire, and sociodemographic questionnaire. Disease activity was assessed by Crohn's disease activity index (CDAI) and ulcerative colitis activity index (UCAI). The correlations of sleep quality, sociodemographic variables, and disease characteristics with IBDQ were investigated. Results: IBDQ-32 mean score was lower in patients who had hospitalization (P = 0.01), poor sleep quality (P < 0.001), anemia (P = 0.03), more severe disease (P = 0.01), and those who had not consumed folic acid (P = 0.01) relative to their counterparts. A multivariate regression analysis identified the predictors of decreased HRQOL as not consuming folic acid (P = 0.008), poor sleep quality (P = 0.014), and disease severity (P = 0.043). Conclusion: Impaired HRQOL was significantly associated with poor sleep quality, lack of folic acid consumption, and disease severity in IBD patients. Therefore, evaluation of folic acid level and efficacy of its supplementation in prospective studies is recommended. Treatment of sleep disturbance with pharmacological agents and nonpharmacological methods should be kept in mind as well.

We aimed to explore the association of sedentary behavior indicators with neck pain among children and adolescents. Methods: A comprehensive review was performed in different databases until the end of January 2022. Odds ratios (ORs) with 95% confidence intervals were used as desired effect sizes to evaluate the association between prolonged screen time or mobile phone (MP) usage and neck pain risk. Results: Among 1651 records, 15 cross-sectional studies were included in the systematic review, and 7 reports were included in the meta-analysis. Our results suggested a significant relationship between prolonged MP use and neck pain (OR = 1.36, 95% CI = 1.001-1.85, I 2 = 40.8%, P value for heterogeneity test = 0.119). Furthermore, a marginally insignificant association was found between prolonged screen time and neck pain (OR = 1.13, 95% CI = 0.98-1.30, I 2 = 60.3%, P value = 0.01); however, after sensitivity analysis and removing one study, this association became significant (OR = 1.30, 95% CI = 1.03-1.64). Moreover, a significant association between prolonged sitting time and neck pain was reported in two studies. Conclusion: Available good-quality evidence reveals a significant mild association between sedentary behavior and the risk of neck pain among children and adolescents. However, longitudinal studies with objective measurement tools are warranted. In particular, potential preventive educational programs are suggested for pediatrics to reduce sedentary behavior and neck pain.
