[Q]: Context: No previous studies have investigated the psychiatric characteristics of patients with postherpetic neuralgia (PHN). Similarly, no studies have been performed on patients with different chronic somatic symptoms due to a defined medical disease to compare the characteristics of psychiatric morbidity associated with each etiology.', 'After completing the subscales of the Symptom Checklist 90-R, a psychiatrist administered the Diagnostic Interview Schedule to all subjects. The psychiatric comorbidity in 35 patients with pain due to PHN was compared with a control group of 34 patients with the nonpainful aversive symptom of vertigo due to a peripheral vestibular disorder that caused unilateral hypofunction.', 'PHN patients had significantly more symptoms of major depression and somatization disorder. No significant differences were found between groups for psychiatric diagnoses. Patients with PHN reported significantly less acutely distressing somatic symptoms.
Answer: These results suggest that the psychiatric symptoms of patients with PHN are distinct from nonspecific acute distress and may be related to the experience of suffering from chronic neuropathic pain. Patients with PHN may not meet criteria for a psychiatric diagnosis, but their psychiatric comorbidity places them at substantial risk for increased pain, suicidal ideation, sustained disability, and the numerous complications of excessive medical evaluation and treatment. Patients with PHN should be evaluated specifically for psychiatric symptoms to reduce potential negative consequences through appropriate treatment.

[Q]: Context: Inflammatory risk factors in childhood, e.g. obesity, impact on carotid artery intima media thickness (CIMT), an early indicator of atherosclerosis. Little is known on potential infectious origins in childhood. We investigated the association between number of reported different childhood infectious diseases and CIMT in adolescence.', "288 SAPALDIA offspring (8-21years) underwent a clinical examination in 2010-2011: anthropometry, blood pressure, CIMT, blood draw (cardiovascular biomarkers, cotinine). Offspring and parents gave information on individuals' and family health, child's vaccination status, infectious diseases and other early life factors. Life-time prevalence of bronchitis, pneumonia, tonsillitis, otitis, mononucleosis, meningitis, appendicitis, and scarlet fever were investigated, separately, and as cumulative infectious disease score. Multilevel adjusted linear regression analysis on the association between subjects' CIMT average and infectious diseases score was performed, stratifying by sex.", 'Youth (mean age 14.8\xa0yrs; 53% female) reported on average 1.3 of the listed infectious diseases; 22% boys and 15% girls reported ≥3 infectious diseases (p\xa0=\xa00.136). Two-thirds were vaccinated according to recommendations (boys 56%, girls 61.5%, p\xa0=\xa00.567). Sex-stratified analyses yielded significantly increased CIMT in boys with ≥3 infectious diseases vs. none (0.046\xa0mm, 95%CI 0.024; 0.068). In girls, the effect was of same direction but statistically non-significant (0.011\xa0mm, 95%CI\xa0-0.015; 0.036).
Answer: The SAPALDIA Youth study complements current evidence on infectious origins of atherosclerosis in adults. The larger effects observed in boys may relate to a higher vulnerability of the vasculature and/or to infectious pathogens. Our data are suggestive of an early impact of childhood infectious diseases on vascular health.

[Q]: Context: Total exercise duration and abnormal QRS score values are treadmill exercise testing (TET) prognostic parameters that have been shown to be significantly and independently associated with cardiac mortality. We evaluated the prognostic value of a new index (M score, Michaelides score) incorporating TET duration and QRS score values in a simple index.', 'In this study, we included 626 patients, who underwent TET and coronary arteriography. Cardiac catheterization showed the presence of coronary artery disease in 64.3% of these patients. The M score was calculated by adding the value of the Athens QRS score to the duration of TET (in minutes). The outcome measure was a composite of myocardial infarction or death. Patients were prospectively followed for 38+/-21 months (median 36 months).', "The composite endpoint was more frequent among the patients of the 1st quartile (M-score values <-5.8). In univariate analysis, mortality of the first-quartile patients was significantly higher (14 vs. 1.1%, P<0.001). In multivariate Cox's regression analysis for age, sex, diabetes, smoking status, hypertension, hypercholesterolemia, maximum ST depression at TET, angina during TET, coronary artery disease on angiography, and echocardiographic left ventricular ejection fraction, the first quartile of M-score values was found to be independently associated with the composite endpoint (relative risk = 3.26, 95% confidence interval = 2.01-5.29, P<0.001).
Answer: This study shows that a new index termed the M score, which incorporates QRS score and exercise duration, predicts mortality and occurrence of myocardial infarction at long-term follow-up of high-risk individuals, independently of TET-induced ST-segment changes.
