Swimming with Swimsuit and Wetsuit at Typical vs. Cold-water Temperatures (26 vs. 18  ℃)
This study aimed to compare three swimming conditions in a swimming flume with water at 26 ℃ (using swimsuit) and 18 ℃ (randomly with swimsuit and wetsuit). Seventeen swimmers (32.4±14.7 years old, 175.6±0.06 cm height, and 70.4±9.8 kg body mass) performed three bouts until exhaustion at a 400-m front crawl pace (24 h intervals). ANOVA repeated measures compared the experimental conditions. Swimming at 26 ℃ with swimsuit evidenced a higher metabolic demand (total energy expenditure; (E)), comparing to 18 ℃ swimsuit (p=0.05) and with 18 ℃ wetsuit (p=0...

Predicting patient-level new-onset atrial fibrillation from population-based nationwide electronic health records: protocol of FIND-AF for developing a precision medicine prediction model using artificial intelligence
Introduction Atrial fibrillation (AF) is a major cardiovascular health problem: it is common, chronic and incurs substantial healthcare expenditure because of stroke. Oral anticoagulation reduces the risk of thromboembolic stroke in those at higher risk; but for a number of patients, stroke is the first manifestation of undetected AF. There is a rationale for the early diagnosis of AF, before the first complication occurs, but population-based screening is not recommended. Previous prediction models have been limited by their data sources and methodologies. An accurate model that uses existing routinely collected data is n...

Changes in coverage among non-elderly adults with chronic diseases following Affordable Care Act implementation
by John D. Goodson, Sara Shahbazi, Zirui Song ImportanceChanges in insurance coverage after the Affordable Care Act (ACA) among non-elderly adults with self-reported chronic conditions across income categories have not been described. ObjectiveTo examine changes in insurance coverage after the ACA among non-elderly adults with chronic conditions across income categories, by geographic region. DesignWe compared self-reported access to health insurance pre-ACA (2010-2013) and post-ACA (2014-2017) for individuals 18-64 years of age with ≥ 2 chronic conditions, including hypertension, heart disease/stroke, emphysema, diabete...

Can This Breakfast Food Reverse Alzheimer ’ s?
I’m sure you’ve noticed how expensive eggs have gotten lately. The price has soared more than any other food in the supermarket…up 60% from one year ago.1 One reason for skyrocketing prices is the ongoing avian flu epidemic. But another reason is that demand for “nature’s perfect food” has increased substantially. And that is good news because eggs are essential for your health – including the fight against Alzheimer’s. And that means they’re worth every penny for the way they protect your brain. Two breakthrough studies back up what I’ve been telling my patients for over three decades… That ...

Interplay of biomechanical, energetic, coordinative, and muscular factors in a 200 m front crawl swim.
This study aimed to determine the relative contribution of selected biomechanical, energetic, coordinative, and muscular factors for the 200 m front crawl and each of its four laps. Ten swimmers performed a 200 m front crawl swim, as well as 50, 100, and 150 m at the 200 m pace. Biomechanical, energetic, coordinative, and muscular factors were assessed during the 200 m swim. Multiple linear regression analysis was used to identify the weight of the factors to the performance. For each lap, the contributions to the 200 m performance were 17.6, 21.1, 18.4, and 7.6% for stroke length, 16.1, 18.7, 32.1, and 3.2% for stroke rat...

The impact of global budgeting on treatment intensity and outcomes
Abstract This paper investigates the effects of global budgets on the amount of resources devoted to cardio-cerebrovascular disease patients by hospitals of different ownership types and these patients’ outcomes. Theoretical models predict that hospitals have financial incentives to increase the quantity of treatments applied to patients. This is especially true for for-profit hospitals. If that’s the case, it is important to examine whether the increase in treatment quantity is translated into better treatment outcomes. Our analyses take advantage of the National Health Insurance of Taiwan’s implementation...

Cardiovascular Disease in Asian Americans Unmasking Heterogeneity ∗
Heart disease is the leading cause of death in the United States, and stroke is the fourth leading cause of death (1). Together, heart disease and stroke accounted for more than $300 billion in health care expenditures and related expenses in 2010 alone (2). However, from 2000 to 2010, death rates attributable to cardiovascular disease (CVD) declined by 31.0%. In the same 10-year period, the actual number of annual deaths from CVD declined by 16.7% (2). Yet in 2010, CVD still accounted for 31.9% of all 2,468,435 deaths, or about 1 of every 3 deaths in the United States (2). Despite this decline, considerable data from th...

Wingbeat kinematics and energetics during weightlifting in hovering hummingbirds across an elevational gradient
Abstract Hummingbirds differentially modify flight kinematics in response to the type of challenge imposed. Weightlifting is associated with increases in stroke amplitude (the angle swept by the wings) to increase the angular velocity of the wings and generate the requisite lift, but only up to 160°. Conversely, flight in hypodense air is accomplished by increasing the angular velocity of the wing through increases in wingbeat frequency and stroke amplitudes, with larger increases in amplitude than seen in weightlifting flight. The kinematic differences between these two challenges may be facilitated by the lower...

Making Sense of Nutraceuticals in China
The Chinese nutraceutical market is considered the third largest in the world after the US and Japan, or the fourth largest if Europe is counted as a single market.Despite strong fundamentals and high rates of annual growth, though, the Chinese market remains some way from realizing its true potential. Its evolution is muddied by ambiguities around what nutraceuticals actually are and how they should be managed.The result has been polarization between over-zealous regulation of so-called health foods, and a grey market where products have skirted approval procedures through questionable positioning or by exploiting alterna...

Seminar The future of atrial fibrillation management: integrated care and stratified therapy
Atrial fibrillation is one of the major cardiovascular health problems: it is a common, chronic condition, affecting 2 –3% of the population in Europe and the USA and requiring 1–3% of health-care expenditure as a result of stroke, sudden death, heart failure, unplanned hospital admissions, and other complications. Early diagnosis of atrial fibrillation, ideally before the first complication occurs, remains a ch allenge, as shown by patients who are only diagnosed with the condition when admitted to hospital for acute cardiac decompensation or stroke.

Metabolomic analysis and pharmacological validation of the cerebral protective effect of 3,4 ‑dihydroxybenzaldehyde on cerebral ischemia‑reperfusion injury
Mol Med Rep. 2023 Jan;27(1):9. doi: 10.3892/mmr.2022.12896. Epub 2022 Nov 11.ABSTRACT3,4‑Dihydroxybenzaldehyde (DBD), one of the active components of Gastrodia elata, has a cerebral protective effect and can effectively combat cerebral ischemia/reperfusion (I/R) injury in rats. However, the metabolite profiles and underlying mechanisms associated with DBD remain unclear. To explore the level of energy metabolism and pharmacological targets in brain tissue following DBD treatment of stroke. The right middle cerebral artery of the rats was occluded for 2 h and reperfused for 24 h to simulate brain I/R injury. Pharmacologic...
