Previous studies on medical education have shown that perceived stress is higher in medical students than in other age-controlled students.[1] As medical students are the underpinning of the medical profession, they must be aware of the adjunct therapy of yoga for the betterment of their own health as well as that of their patients. \u0000 \u0000As defined by the World Health Organization, health is “a state of complete physical, mental, and social well-being and not merely absence of disease or infirmity.”[2] This definition has been expanded to embrace the ability to “lead a socially and economically productive life.”[3] Apart from causing mental turbulences, anxiety and stress have unfavorable effects on the body that may evolve into chronic conditions, if left untreated.[4] Stress has been linked to harmful effects on the immune system,[5,6] while anxiety has been associated with coronary heart disease,[7] decreased quality of life,[8] and suicidal behavior.[9] \u0000 \u0000Although yoga has been practiced for over 5000 years, it has only newly gained popularity worldwide.[10] The drill originated in India and has been applied to relieve both mental and physical infirmities,[11,12,13] for it incorporates postures, breathing techniques, and meditation. From the yogic perspective, the body and the mind are so interconnected that they are essentially inseparable.[14] Whatever affects the body must impact the mind and vice-versa. Since the mind exists throughout the body and pervades its every particle, the yogic techniques which are implemented to stretch, strengthen, and otherwise improve, and develop the body must have a correspondingly deep effect on the mind and the emotions as well.[14] \u0000 \u0000Psychological stress and yoga are believed to be reciprocally related. Stress induces imbalance of the autonomic nervous system with decreased activity of the parasympathetic nervous system and increased activity of the sympathetic nervous system.[15] Autonomic imbalance is closely associated with anxiety. Scientific evidence supports the belief that yoga benefits physical and mental health via down-regulation of the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system.[16] Deep relaxation and calming down of the mind lead to effective reduction in blood pressure, pulse rate, and respiratory rate by decreasing the amount of cortisol which typically increases during the body's response to stress.[14] Yoga, also, reduces the level of acetylcholine, which leads to the reduction in the sympathetic nervous system activity and increase in vagal activity.[14] As a result, it reduces psychological conflicts, suppressions, and hypersensitivities, which are recognized as the triggering factors for psychosomatic problems. \u0000 \u0000Moreover, stress is strongly concomitant with muscle tension.

I would like to compliment the authors for the commanding effort to put together a burning issue of psychological and physical stress and burnout among the medical students. The issue is often neglected both by the vulnerable population of students as well as the health-care community itself. The article definitely brings attention on the need for coping strategies and also puts together various methods for the physical and psychological wellbeing of the doctors-in-making. \u0000 \u0000Yoga, a mind-body practice of ancient Indian origin has gained significance in recent times due to its health benefits. Various practices of yoga have been found beneficial to attenuate stress and enhance functionality among medical students. Despite an array of coping strategies, yoga practices are found to reduce perceived stress,[2,3,4,5] anxiety,[4,6,7,8] markers of stress such as cortisol,[9] improved general health and well-being,[5,10,11] physical and physiological health,[6,12,13] improve cognition[14] as well as cultivation of positive emotions[2,3,7] such as empathy, compassion, and self-regulation. There is evidence of a reduction in work-related stress and better autonomic balance with the practice of yoga in health professionals.[15] The studies indicate not just the psychological benefits of yoga, but the physical benefits such as better autonomic balance, enhanced respiratory endurance, auditory and visual reaction times as well as muscle strength.[13] Few research studies showing the beneficial effects of yoga among medical students are listed in Table 1. \u0000 \u0000 \u0000 \u0000Table 1 \u0000 \u0000Findings of research studies on yoga for medical students \u0000 \u0000 \u0000 \u0000One of the most important stressors among medical students is the examination. Malathi and Damodaran and Malathi et al.[8,12] have found yoga to be beneficial in modulating the response to stress during the examination. In addition, studies indicate that yoga could enhance the examination performance and reduce anxiety.[16] Another important area of concern brought out by Fares et al. is the lack of self-care behavior among medical students.[1] Yoga and mindfulness-based practices have demonstrated beneficial impact on the self-care behavior in counselors, who encounter similar health issues of that of medical students.[17] \u0000 \u0000From the review of existing scientific literature on the application of yoga in medical students, it is evident that yoga is a self-practiced, low cost, safe, efficacious as well as acceptable tool benefitting the target population. There are positive outcomes for the medical students in their physical, psychosocial, and emotional health. The practices that are safely used in the wellbeing of student community include asana (physical postures), pranayama (breathing practices), dhyana (meditation), mindfulness-based stress relaxation, and mind sound resonance technique (M","PeriodicalId":19703,"journal":{"name":"North American Journal of Medical Sciences","volume":"8 4","pages":"200-2"},"PeriodicalIF":0.0,"publicationDate":"2016-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4866479/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34572829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incomplete closure of the septum primum and septum secundum results in patent foramen ovale (PFO). On the other hand, migraine is a common condition characterized by unilateral headache associated with nausea, photophobia, and phonophobia. These two conditions may be related to each other. \u0000 \u0000Various mechanisms have been described to explain this relation. Subclinical emboli, as well as metabolites from the venous circulation bypass the pulmonary circulation through the PFO. They enter the systemic circulation and result in irritation of the trigeminal nerve and brain vasculature. This may trigger a migraine. \u0000 \u0000A small double-blind crossover study has demonstrated that aspirin, an antiplatelet drug may reduce the formation of platelet-fibrin complexes and improve a migraine. It may be possible that increased platelet activation may be a risk factor for a migraine through the action of serotonin. Transient hypoxemia resulting from shunting of blood through the PFO causes microinfarcts in the brain. It may lead to a migraine. PFO may predispose to subclinical ischemia and paradoxical embolism that may result in triggering the migraine.[1] Another study has postulated the eustachian valve, Chiari's network, and migraine with aura can be adjunctive risk factors for paradoxical embolism in the evaluation of both symptomatic and asymptomatic PFO patients.[2] It has been demonstrated that PFO is not just an example of migraine comorbidity but exerts a causal effect in the triggering of the aura by applying the criteria proposed by Bradford Hill.[3] \u0000 \u0000Epidemiologic data have shown that PFO and migraine are related. Two Italian groups were the first to report, in case-control studies, a significantly higher prevalence of PFO in subjects with a migraine with aura. They have used transcranial Doppler ultrasonography (TCD) for evaluation of patients. A study of young cryptogenic stroke patients has shown increased prevalence of a migraine in patients with PFO. A retrospective study showed that migraine patients with PFO have higher right-to-left shunting compared to controls. In a meta-analysis of seven studies, it was concluded that there was only low-grade evidence supporting the association between PFO and migraine.[1] A study published on 2012 demonstrated that the intravenous injection of air bubbles results in bioelectrical disturbances in the brain of patients with a migraine with aura. They have large right-to-left cardiac shunts. On the contrary, this effect was absent in patients with equally large right-to-left cardiac shunts, but without a migraine.

Serum vitamin D rarely exceeded 100 ng/mL, never reached toxic levels, and there were no significant change in serum calcium or eGFR.</p>","PeriodicalId":19703,"journal":{"name":"North American Journal of Medical Sciences","volume":"8 3","pages":"156-62"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/9e/a0/NAJMS-8-156.PMC4821095.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34433090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
