Exposure to secondhand smoke from burning tobacco products causes premature death and disease, including coronary heart disease, stroke, and lung cancer among nonsmoking adults and sudden infant death syndrome, acute respiratory infections, middle ear disease, exacerbated asthma, respiratory symptoms, and decreased lung function in children (1,2). The U.S. Surgeon General has concluded that there is no risk-free level of exposure to secondhand smoke (1). Previous CDC reports on airport smoke-free policies found that most large-hub airports in the United States prohibit smoking (3); however, the extent of smoke-free policies at airports globally has not been assessed...

BACKGROUND: Cerebral air embolism is a rare cause of cerebral infarction. In cerebral air embolism, T2 star-weighted imaging shows numerous spotty hypointense signals. Previous reports have suggested that these signals represent air in the brain and are gradually diminished and absorbed. We experienced two cases of cerebral air embolism, and in one of them, we conducted an autopsy. CASE PRESENTATION: Case 1 was a 76-year-old Japanese man with lung cancer and emphysema...

Many high-altitude vertebrates have evolved increased capacities in their oxygen transport cascade (ventilation, pulmonary diffusion, circulation and tissue diffusion), enhancing oxygen transfer from the atmosphere to mitochondria. However, the extent of interspecies variation in the control processes that dictate hypoxia responses remains largely unknown. We compared the metabolic, cardiovascular and respiratory responses to progressive decreases in inspired oxygen levels of bar-headed geese (Anser indicus), birds that biannually migrate across the Himalayan mountains, with those of Andean geese (Chloephaga melanoptera) and crested ducks (Lophonetta specularioides), lifelong residents of the high Andes...

Movement is the basic attribute of life. It is not surprising that the return to regular physical activity is a very effective and cheap means of preventing and treating most non-cummunicable diseases. Therefore, every physician should be able to prescribe a suitable physical activity. The minimum amount of physical activity with proven effects in primary prevention of chronic diseases is relatively low: 150 minutes of moderate physical activity or 75 minutes of high intensity exercise per week or a combination of the two...

Asymptomatic "paradoxic" severe low-flow low-gradient aortic stenosis with preserved ejection fraction (PAS) constitutes a challenging condition where the optimal management and follow-up remain elusive. We evaluated the clinical outcome in patients with PAS as compared to asymptomatic patients with moderate (MAS) or classical severe aortic stenosis (CAS). Consecutive asymptomatic moderate or severe aortic stenosis patients without concomitant other heart or lung disease (n = 121) were invited. Participants (n = 74) were assigned to three subgroups with regard to degree of aortic stenosis: MAS (n = 25), CAS (n = 22) and PAS (n = 27)...

BACKGROUND: Late-onset poststroke seizure is highly associated with epilepsy but the incidence of it is variable due to different definition and follow-up time. We conducted a meta-analysis to determine the incidence of poststroke seizure and analyze the discrepancies among published studies. METHODS: We searched the literature for relevant articles published in English between January 1, 1990, and December 31, 2014, by using the following search terms: "seizures after stroke," "poststroke seizures," "epilepsy after stroke," "poststroke epilepsy," "incidence," and "follow-up...

INTRODUCTION: The acute complications of aneurysmal subarachnoid hemorrhage (aSAH) often lead to readmissions, which are linked to hospital reimbursement. The national rates, causes, risk factors, and outcomes associated with 30-day and 90-day readmission following aSAH have not previously been reported. METHODS: The Nationwide Readmissions Database was queried from January through September 2013 for all patients (age ≥ 18) with a diagnosis of aSAH. Data points included demographics, comorbidities, complications, and discharge outcomes...

<i>Objective</i>: Electrical impedance tomography (EIT) shows potential for radiation-free and non-invasive hemodynamic monitoring. However, many factors degrade the accuracy and repeatability of these measurements. Our goal is to estimate the impact of this variability on EIT-based monitoring of two important central hemodynamic parameters: stroke volume (SV) and pulmonary artery pressure (PAP). <i>Approach</i>: We performed simulations on a 4D (3D + t) bioimpedance model of a human volunteer to study the influence of four potential confounding factors (electrode belt displacement, electrode detachment, changes in hematocrit and lung air volume) on the performance of EIT-based SV and PAP estimation...

OBJECTIVES: Studies have showed the associations between different definitions of metabolic syndrome (MetS) and risk of ischemic stroke were inconsistent. In this study, we compared associations of different MetS definitions with ischemic stroke in Chinese elderly population. METHODS: A total of 1713 individuals aged 70-84years from Rugao Longevity and Ageing Study were analyzed. The MetS was defined by four different criteria: Chinese Adult Dyslipidemia Prevention Guide, International Diabetes Federation (IDF), Updated ATPIII (Updated ATPIII) by American heart association/American heart, lung and blood institute (AHA/NHLBI), and Joint Interim Statement(JIS) recommended by IDF and the American heart association/American national institutes of health/American heart, lung and blood institute (AHA/NIH/NHLBI)...

In recent years, research on the spatiotemporal distribution and health effects of fine particulate matter (PM2.5) has been conducted in China. However, the limitations of different research scopes and methods have led to low comparability between regions regarding the mortality burden of PM2.5. A kriging model was used to simulate the distribution of PM2.5 in 2015 and 2016. Relative risk (RR) at a specified PM2.5 exposure concentration was estimated with an integrated exposure-response (IER) model for different causes of mortality: lung cancer (LC), ischaemic heart disease (IHD), cerebrovascular disease (stroke) and chronic obstructive pulmonary disease (COPD)...

BACKGROUND: Sedentary behavior (SB) is, irrespective of a person's physical activity levels, associated with a wide range of deleterious outcomes such as diabetes, stroke and associated premature mortality. There are no nationally representative, multi-national, population-based studies investigating the relationship between SB, chronic conditions, and physical multimorbidity (i.e., two or more chronic physical conditions). Thus, this cross-sectional study aimed to assess the association between chronic conditions, physical multimorbidity and SB among community-dwelling adults in six low- and middle-income countries (LMICs)...

Background -Hemodynamic variables, such as cardiac index and right atrial pressure (RAP), have consistently been associated with survival in pulmonary arterial hypertension (PAH) at the time of diagnosis. Recent studies have suggested pulmonary arterial compliance (PCa) may also predict prognosis in PAH. The prognostic importance of hemodynamic values achieved after treatment initiation is less well established. Methods -Our objective was to evaluate the prognostic importance of clinical and hemodynamic variables during follow-up, including PCa, after initial management in PAH...

The CHADS2, CHA2DS2-VASc, and R2CHADS2 scores are well-known predictors of stroke caused by atrial fibrillation (AF), but no studies have evaluated their use for stratifying all-cause mortality risk in patients discharged for systolic heart failure (SHF) with or without AF.This study analyzed data in the Taiwan Society of Cardiology-heart failure with reduced ejection fraction (TSOC-HFrEF) registry. These data were obtained by a prospective, multicenter, observational survey of patients treated at 21 medical centers in Taiwan after hospitalization for acute, pre-existing or new onset SHF from May, 2013 to October, 2014...

STUDY OBJECTIVES: In heart failure (HF), we observed two patterns of hyperpnea during Cheyne-Stokes respiration with central sleep apnea (CSR-CSA): a positive pattern where end-expiratory lung volume remains at or above functional residual capacity, and a negative pattern where it falls below functional residual capacity. We hypothesized the negative pattern is associated with worse HF. METHODS: Patients with HF underwent polysomnography. During CSR-CSA, hyperpnea, apnea-hyperpnea cycle, and lung to finger circulation times (LFCT) were measured...
