Ziaee V, Kordi R, Alizadeh R, Afsharjoo Hr, Yunessian M, Halabchi F ,
Volume 60, Issue 3 (14 2002)
Abstract

Background: To determine the incidence and risk factors of acute mountain sickness (A - AMS) in pilgrims. Although it is well known that western trekkers suffer from acute mountain sickness (AMS) in other mountains, not much is documented about the incidence of AMS in the Damavand Mountains, Iranian population that go to high altitude and its related contributing factors.

 Materials and Methods: The design was a cross sectional study. During six weeks (in summer 2000) a population of 459 pilgrims was studied. The period of the study was six weeks in summer AMS symptoms, were assessed by an extensively used standard questionnaier (Lake Louise), applied at 2900 m, after than arrive at 4200 m above sea level, and during descent from summit Damavand (at 4200 m) at Damavand in Iran Alborz Mountain.

Results: The overall incidence of A.M.S. was 60.8 percent. Climbers had 13-71 years and 67.8 percent of the study population was men. Men did not differ significantly higher rate of AMS from women. The incidence being increased in those who residence at an altitude below 600 m, climbed fast, amateur climbers, a previous AMS experience or high altitude illness, a history of AMS at ascent to Damavand and ascent time at night (6pm-6am). It was weakly dependent to rate of ascent (from 2800 m up 4200 m less that 4 hours) and sleep in 4200 m. The incidence of AMS was unrelated to sex, age, body mass index (BMI), height, weight, smoking, to the load carried and knapsack and spent more than 15 hours in shelter (at 4200 m). So it was independent of rate of ascent in the higher altitude (from 4200 m to 5671 m), speed of descent and family history of AMS.

 Conclusions: Data show a strong relation between experiences mountaineer, history of AMS, ascent time at night and the incidence of acute mountain sickness in 459 climbers studied at high altitudes that didn’t report previously.


Acute Mountain Sickness among overnight hotel guests:  prevalence, symptoms and signs
Halabchi F, Mazaheri R,
Volume 66, Issue 8 (5 2008)
Abstract

Background: Altitude diseases, the most frequent of which is acute mountain sickness (AMS), are among the most common and serious problems that recreational and professional mountain athletes may encounter. If left undiagnosed, they may lead to lethal consequences. In a cross sectional study, we investigate the prevalence of AMS disorder among the overnight guests of a mountain resort hotel.

Methods: Overnight guests staying at Hotel Tochal (elevation 3545 m), near Tehran, Iran, in the winter of 2006 constituted the study participants. A questionnaire, including demographic data, proposed risk factors and Lake Louise score, was completed by a physician for all who had headache or other symptoms of AMS. Data from daily hotel reception records were also collected.

Results: Overall, 328 persons stayed at this hotel for at least one night during the study period. Among these, 47 persons (14.3%) were admitted to the clinic for headache. According to the physician's diagnoses, only 34 guests (10.4% 95% CI: 7.1-13.7%) were affected by AMS. The concurrent symptoms of headache and vertigo or insomnia had the highest predictive value for AMS diagnosis. Ambiguous headache had a higher predictive value than other types of headache.

Conclusions: Despite the height of Tochal peak and the frequent use of high speed telecabin, it seems that the frequency of AMS is lower than that found in other studies on similar altitudes. However, more research should be done in this regard.

Abstract
Background: Today obesity and overweightness are the major health problem all over the world. The relation between decreasing serum level of vitamin D and some chronic diseases such as diabetes and obesity was shown in the available studies. The aim of this study was to determine the prevalence of vitamin D deficiency among obese and overweight Iranian population and its relation with age, sex, occupation, body fat percentage and body weight according to body mass index. Methods: In a descriptive cross-sectional study, all patients who were referred to obesity clinic of Imam Khomeini Hospital, Tehran, for weight management throughout one year were included to the study. The prevalence of vitamin D deficiency with serum level lower than 30 ng/ml among 107 subjects was evaluated. The data were analyzed by SPSS, ver. 19 (SPSS, Inc., Chicago, IL, USA). Quantitative variables were presented as mean±SD and qualitative variables were presented as relative frequency. The groups were compared with independent samples t-test and Chi-square test. The level of significance for comparing the groups was considered at P<0.05. Results: In 107 participants, vitamin D deficiency in 81 subjects (75.7%) was reported. The prevalence of deficiency in participants with body mass index between 25 to 29.9, 30 to 34.9 and equal or greater than 35 kg/m2 was 77.3%, 83.7% and 69.4%, respectively. However, the differences between overweight and obese groups were not significant (P=0.193). The prevalence of moderate and severe vitamin D deficiencies among the participants was 50.5% and 25.2 %, respectively. Vitamin D deficiency was more common in participants below 50 years of age compared with those older than fifty (P=0.001). Conclusion: The prevalence of vitamin D deficiency was high in obese and overweight population especially among individuals younger than 50 years. It seems that, it is necessary to add prevention and management of this deficiency to obesity treatment protocols especially in the young adults.
Sudden cardiac death in athletes and its preventive strategies: review article

Volume 75, Issue 9 (December 2017)
Abstract
Sudden cardiac death in sport, although rare, but is a tragic event, attracting the media and public attention. Sport and exercise may act as a trigger for sudden cardiac death. Risk of sudden death in young athletes with cardiovascular disease is 2.5 times more frequent than non-athlete individuals. More than 90% of cases of sudden death occur during or immediately after training or competition. Incidence of sudden cardiac death in any population, including athletes, is related to multiple factors such as gender, age, race, nationality, diagnostic screening methods and preventive measures for sudden cardiac death. Otherwise, incidence rate of sudden cardiac death is linked to the used definition and method of diagnosis. Different cardiovascular disorders may result in death of young athletes and hypertrophic cardiomyopathy, congenital coronary anomalies, arrhythmogenic right ventricular dysplasia and aortic rupture are among the most common causes. Marfan syndrome, dilated cardiomyopathy, viral myocarditis, Wolff-Parkinson-White (WPW) syndrome, congenital long QT syndrome, Brugada syndrome and commotio cordis are reported as other etiologies. In older athletes (more than 35 years), ischemic coronary heart disease is responsible for majority of the cases similar to the general population. Because the outcome of sudden cardiac arrest in sports is very poor except in few cases, proper national strategies are needed to diminish the burden of sudden death in young athletes. It seems that there are two main strategies to achieve this goal: A) Primary prevention with use of purposeful pre-participation evaluation programs. This evaluation should focuss on the proper history and physical examination. Nevertheless, there is significant debate between American and European countries regarding the use of paraclinical investigations (especially ECG). American heart association does not recommend ECG as an essential part of evaluation. In contrast, European society of cardiology and international olympic committee advocate ECG for all athletes younger than 35 years. However, all evaluations should be based on national, generally accepted standards and done by well-educated experts. B) Setting evidence-based and updated protocols for early and effective cardiopulmonary resuscitation (CPR), attendance of well equipped medical staff and early access to automated external defibrillator (AED) in all sport events and implementing CPR education in all coaching training courses.
