Sleep duration, vital exhaustion and perceived stress among pregnant migraineurs and non-migraineurs

<p>Abstract</p> <p>Background</p> <p>Migraine has been associated with sleep disorders in men and non-pregnant women, but little is known about sleep complaints among pregnant migraineurs.</p> <p>Methods</p> <p>A cohort of 1,334 women was interviewed during early pregnancy. At the time of interview we ascertained participants' migraine diagnosis status and collected information about sleep duration before and during early pregnancy, daytime sleepiness, vital exhaustion and perceived stress during early pregnancy. Multivariable logistic regression procedures were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of short/long sleep duration, excessive daytime sleepiness, vital exhaustion and elevated perceived stress associated with a history of migraine.</p> <p>Results</p> <p>Approximately 19.4% of the cohort (n = 259) reported having a medical diagnosis of migraine prior to the study pregnancy. Compared with women without migraine, the multivariable-adjusted ORs (95% CI) among migraineurs for short sleep duration before and during early pregnancy were 1.51 (1.09-2.09), and 1.57 (1.11-2.23), respectively. The corresponding OR (95% CI) for long sleep duration before and during pregnancy were 1.33 (0.77-2.31) and 1.31 (0.94-1.83), respectively. A modest and statistically insignificant association between migraine history and excessive daytime sleepiness in early pregnancy was noted (OR = 1.46; 95% CI 0.94-2.26). Migraineurs had an increased risk of vital exhaustion (OR = 2.04; 95% CI 1.52-2.76) and elevated perceived stress (OR = 1.57; 95% CI 1.06-2.31). Observed associations were more pronounced among overweight migraineurs.</p> <p>Conclusions</p> <p>These data support earlier research documenting increased risks of sleep disorders among migraineurs; and extends the literature to include pregnant women. Prospective studies are needed to more thoroughly explore factors that mediate the apparent migraine-sleep comorbidity among pregnant women.</p

Migraine in women: the role of hormones and their impact on vascular diseases

Migraine is a predominantly female disorder. Menarche, menstruation, pregnancy, and menopause, and also the use of hormonal contraceptives and hormone replacement treatment may influence migraine occurrence. Migraine usually starts after menarche, occurs more frequently in the days just before or during menstruation, and ameliorates during pregnancy and menopause. Those variations are mediated by fluctuation of estrogen levels through their influence on cellular excitability or cerebral vasculature. Moreover, administration of exogenous hormones may cause worsening of migraine as may expose migrainous women to an increased risk of vascular disease. In fact, migraine with aura represents a risk factor for stroke, cardiac disease, and vascular mortality. Studies have shown that administration of combined oral contraceptives to migraineurs may further increase the risk for ischemic stroke. Consequently, in women suffering from migraine with aura caution should be deserved when prescribing combined oral contraceptives

Headache during gestation: Evaluation of 1101 women

Objective: The purpose of this study was to evaluate the presence of headache in women with a previous history or newonset headache during the current gestation, classify the findings, and describe the clinical characteristics and outcome of the headache. Methods: From January/1998 to June/2002 we prospectively evaluated 1101 pregnant women (12-45 years old), with a history of headache, at two prenatal clinics and all inpatient obstetric public hospital. Women were interviewed using a semi-structured questionnaire during the first, second, and third gestation trimesters and immediately after delivery, All interviews were conducted by one of the authors, using the International Headache Society Classification (IHSC-2004). Results: In 1029 women there was a history of headache prior to the Current pregnancy, 36 (3.4%) women first experienced headache during this pregnancy and 40 patients experienced new types of headache. In these 76 patients with new onset headache during pregnancy, 40 had secondary headache (52.6%), 31 had primary headache (40.8%), and 5 had headache not classified elsewhere (6.6%). According to IHSC-2004 criteria, we found migraine in 848/1029 women (82.4%), with pregestational headache. Conclusions: Most of the pregnant women presented with headache, mainly in migraine, prior to pregnancy, and most of the headaches improved or disappeared during the second and third In a relatively small number of pregnant women, a new type of headache started during the gestation.34218719

Academic career in medicine - requirements and conditions for successful advancement in Switzerland

BACKGROUND: Within the framework of a prospective cohort study of Swiss medical school graduates a sample of young physicians aspiring to an academic career were surveyed on their career support and barriers experienced up to their sixth year of postgraduate training. METHODS: Thirty-one junior academics took part in semi-structured telephone interviews in 2007. The interview guideline focused on career paths to date, career support and barriers experienced, and recommendations for junior and senior academics. The qualitatively assessed data were evaluated according to Mayring's content analysis. Furthermore, quantitatively gained data from the total cohort sample on person- and career-related characteristics were analyzed in regard to differences between the junior academics and cohort doctors who aspire to another career in medicine. RESULTS: Junior academics differ in terms of instrumentality as a person-related factor, and in terms of intrinsic career motivation and mentoring as career-related factors from cohort doctors who follow other career paths in medicine; they also show higher scores in the Career-Success Scale. Four types of career path could be identified in junior academics: (1) focus on basic sciences, (2) strong focus on research (PhD programs) followed by clinical training, (3) one to two years in research followed by clinical training, (4) clinical training and research in parallel. The interview material revealed the following categories of career-supporting experience: making oneself out as a proactive junior physician, research resources provided by superior staff, and social network; statements concerning career barriers encompassed interference between clinical training and research activities, insufficient research coaching, and personality related barriers. Recommendations for junior academics focused on mentoring and professional networking, for senior academics on interest in human resource development and being role models. CONCLUSION: The conditions for an academic career in medicine in Switzerland appear to be difficult especially for those physicians combining research with clinical work. For a successful academic career it seems crucial to start with research activities right after graduation, and take up clinical training later in the career. Furthermore, special mentoring programs for junior academics should be implemented at all medical schools to give trainees more goal-oriented guidance in their career
