BACKGROUND

Polyphenol intake is associated with reduced cardiometabolic risk factors such as dyslipidemia, hyperglycemia, and obesity. Pigmented rice varieties such as red, purple, and black rice contain polyphenols; however, are not commonly consumed. Apart from price and sensory properties, awareness of its availability, perception of health benefits, and intent to purchase may influence consumer preference and consumption.

This study aimed to develop and validate a short questionnaire designed to determine awareness of the availability, perception of health benefits, and intent to purchase pigmented rice.

The study included three phases: (1) tool development, (2) expert validation, and (3) reliability testing. Questions were initially evaluated for clarity and relevance by two Nutritionist-Dietitians and then by seven lay individuals through a focus group discussion. Following the revision, seven food and nutrition experts evaluated the face and content validity of the questionnaire. Validity was assessed via computation of Item and scale content validity indices and kappa statistics. The validated tool was then tested for internal consistency and parallel form reliability of English and Filipino versions among lay individuals (n=31) and then evaluated for reliability based on Cronbach’s alpha and Intraclass correlation coefficients.

The questionnaire was found to have an acceptable face (I-CVI: 1.00; S-CVI/UA: 1.00; K=1.00) and content validity (I-CVI: 0.86-1.00; S-CVI/UA: 0.96-1.00; K= 0.85-1.00) and reliability (α=0.96-1.00).

The developed questionnaire is a valid and reliable tool for assessing awareness of the availability, perception of health benefits, and intent to purchase pigmented rice.

BACKGROUND: Regional disparities in the working conditions of medical doctors have not been fully assessed in Japan. We aimed to clarify these differences in hospital characteristics: doctors' workload, wages, and popularity among medical students by city population sizes. METHODS: We targeted 423 teaching hospitals certified by the Japanese Society of Internal Medicine and assessed the working conditions of physicians specializing in internal medicine. We calculated their workload (the annual number of discharged patients per physician) and retrieved data on junior residents' monthly wages from the Resinavi Book which is popular among medical students in Japan to know the teaching hospital's information and each hospital's website. Furthermore, we explored the interim matching rate of each hospital as its popularity among medical students. Next, we classified cities in which all hospitals were located into eight groups based on their population size and compared the characteristics of these hospitals using a one-way analysis of variance. RESULTS: The average workload was 110.3, while the average workload in hospitals located in most populated cities (≥ 2,000,000) was 88.4 (p < 0.05). The average monthly wage was 351,199 Japanese yen, while that in most populated cities was 305,635.1 Japanese yen. The average popularity (matching rate) was 101.9%, and the rate in most populated areas was 142.7%, which was significantly higher than in other areas. CONCLUSIONS Hospitals in most populated areas had significantly lower workloads and wages; however, they were more popular among medical students than those in other areas. This study was the first to quantify the regional disparities in physicians' working conditions in Japan, and such disparities need to be corrected.

PURPOSE: Scholarly works have reported about the nurses' salary and its impact on job satisfaction, nurse turnover, retention, work condition, and provision of nursing care. However, studies are either focused on the nurses in government hospitals or nurses working outside the country. Thus, the study aims to explore and describe the lived experience of nurses employed in private hospitals in Albay province, the Philippines, and explicate the need for better pay. DESIGN: The study used a qualitative design, specifically a descriptive phenomenology approach. METHODS: Purposive sampling and in-depth interviews were conducted among seventeen (17) nurse informants. The audio-recorded interviews were transcribed verbatim and analyzed following the seven-stage process as described by Colaizzi (1978) for data coding and identifying themes. The same process of analysis performed among the responses or data gathered through electronic communication platforms. FINDINGS: Four themes and nine sub-themes were identified. The first theme is 'Over but under,' which includes three sub-themes: (1) Over-worked, underpaid working conditions, (2) Finding an additional source of income as a result of low-wages, (3) More nurses are produced, but less are staying in the country, (4) Required by law in the country but not permitted by low salary. The second theme is 'Same but different,' which includes three sub-themes: (1) The Nursing profession is akin to others, yet uncompensated, (2) Work demands are comparable to government hospitals. The third theme is 'Caring but uncared-for,' which includes two sub-themes: (1) Psychologically upsetting, (2) Stimulates nurses transition. The fourth theme is 'Selfless foresight,' which include only one sub-theme (1) Increasing the salary attracts nurses to stay in the country. CONCLLUSION AND RECOMMENDATIONS: The study results showed that nurses in private hospitals need better remuneration as they experience poor work conditions. Also, it described a low salary that impacts the nurses' workload, their physical and mental health, their socio-economic being, their ability to avail professional development, the retention or turnover, and the provision of nursing care. The study findings suggest data triangulation of the study in some other private hospitals outside the region and explore strategies for increasing nurses' retention and satisfaction. Nonetheless, these efforts will robust the empirical data about the need for better pay among nurses in the private sector.

E-cigarettes (ECs) and heated tobacco products (HTPs) have become popular in Korea; hence, it is important to determine whether ECs and HTPs are less hazardous than combustible cigarettes (CCs). In general, the levels of harmful and potentially harmful constituents (HPHCs) are lower in ECs and HTPs than in CCs, although the levels of some heavy metals and HPHCs are higher in ECs and HTPs than in CCs. ECs and HTPs showed possible adverse effects on respiratory and cardiovascular system function, which could result in chronic respiratory and cardiovascular system diseases in animals. An analysis of biomarkers showed that ECs had possible adverse health effects on the respiratory and cardiovascular systems, in addition the effects of HTP on respiratory and cardiovascular systems were not significantly different than those of CC. Epidemiological studies identified positive associations between EC use and asthma, chronic obstructive pulmonary disease, and myocardial infarction. Only one epidemiologic study reported a positive association between ever using HTPs and asthma, allergic rhinitis, and atopic dermatitis among adolescents. Modelling studies of ECs did not show consistent findings regarding the health effects compared with those of CCs. A modeling study of HTPs, performed by tobacco industry, has been criticized for many unfounded assumptions. Lower levels of HPHCs in ECs and HTPs, compared with those in CCs, cannot be directly translated into health benefits because the relationship between exposure and effects is non-linear for cardiovascular diseases and because the duration of exposure is more important than the level of exposure in determining lung cancer mortality. In summary, there is no definite health benefit in using ECs or HTPs instead of CCs, for the individual or the population; hence, tobacco control measures should be the same for ECs, HTPs, and CCs. ECs and HTPs have become popular in Korea; hence, it is important to determine whether ECs and HTPs are less hazardous than CCs.

PURPOSE: Metabolic syndrome (MetS) is a major public health problem related to increased risks of cardiovascular disease and type 2 diabetes. We investigated whether recommended levels of leisure time physical activity (LTPA) decrease the risk of MetS in a community-based prospective cohort study (Ansung and Ansan cohort).MATERIALS AND METHODS: A total of 3910 adults (1890 men, 2020 women) without MetS examined in 2001–2002 (baseline) were included in this study and followed up from 2013 to 2014. We measured LTPA energy expenditure using the standard metabolic equivalent value [metabolic equivalent of task (MET)-h/wk]. Individuals were categorized into five groups (physically inactive, 0.1 to <7.5, 7.5 to <15.0, 15.0 to <22.5, 22.5 to <40.0, and ≥40.0 MET-h/wk).RESULTS: The mean follow-up period was 11.8 years. Among the cohort, 482 men (25.5%) and 541 women (26.8%) were diagnosed with newly developed MetS. Multivariate logistic analysis revealed a 4.4% lower MetS risk among those performing two to three times the recommended minimum of 7.5 MET-h/wk [multivariate relative risk (RR), 0.956; 95% confidence interval (CI), 0.654–1.398] and a 21.9% lower risk among those performing three to four times the physical activity minimum (multivariate RR, 0.781; 95% CI, 0.574–1.063). This association was only significant in females performing three to four times the minimum (crude RR, 0.655; 95% CI, 0.432–0.994).CONCLUSION: We noted that physical activity at more than 2 times the recommended minimum prevents MetS. Healthcare professionals should encourage inactive adults to be physically active during their leisure time to take advantage of its health benefits.

benefits such as antioxidant and anti-inflammatory effects. However, it is unknown whether it has protective effects against oxidative stress-induced cell death. We investigated whether UA ameliorates H₂O₂-induced neuronal cell death.MATERIALS/METHODS: We induced oxidative damage with 300 µM H₂O₂ after UA pretreatment at concentrations of 1.25, 2.5, and 5 µM in SK-N-MC cells. Cytotoxicity and cell viability were determined using the CCK-8 assay. The formation of reactive oxygen species (ROS) was measured using a 2,7-dichlorofluorescein diacetate assay. Hoechst 33342 staining was used to characterize morphological changes in apoptotic cells. The expressions of apoptosis proteins were measured using Western blotting.RESULTS: UA significantly increased cell viability and decreased intracellular ROS production in a dose-dependent manner in SK-N-MC cells. It also decreased the Bax/Bcl-2 ratio and the expressions of cytochrome c, cleaved caspase-9, cleaved caspase-3, and cleaved PARP. In addition, it suppressed the phosphorylation of the p38 mitogen-activated protein kinase (MAPK) pathway.CONCLUSIONS: UA attenuates oxidative stress-induced apoptosis via inhibiting the mitochondrial-related apoptosis pathway and modulating the p38 MAPK pathway, suggesting that it may be an effective neuroprotective agent.]]>

BACKGROUND: Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. METHODS: This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of 33 authors—primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. RESULTS: CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers cardiovascular mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. CONCLUSION: Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

PURPOSE: Asthma is a common disease that is expensive and burdensome for patients. Inhaled corticosteroids (ICS) are the most important drugs for asthma treatment and are often prescribed long-term. However, the use of ICS has been reported to increase pneumonia, though this remains controversial. We evaluated whether the use of ICS increases the risk of pneumonia in asthmatic patients using the Health Insurance Review and Assessment Service (HIRA) database in Korea. METHODS: The Asthma Management Adequacy Assessment was performed by the HIRA in Korea. Patients with claimed insurance benefits for asthma disease codes and who were prescribed asthma medications more than 2 times were enrolled. Patient demographics, asthma medications, healthcare use, and complications were analyzed. RESULTS: The total number of asthma patients was 831,613. Patients using ICS were older and had more comorbidities than those not using ICS; they also visited outpatient clinics and emergency departments, and were more often hospitalized. Pneumonia and other complications occurred more often in patients using ICS, and they used more respiratory medications, except for theophylline. Multiple logistic regression analysis showed that ICS prescription was associated with pneumonia (odds ratio, 1.38; 95% confidence interval, 1.36-1.41). Age, sex, medical care, use of secondary and tertiary hospitals, and hospitalization due to asthma in the previous year were also associated with pneumonia. CONCLUSIONS: ICS use was associated with increasing pneumonia in asthmatic patients in Korea. Therefore, it is critical to acknowledge that the use of ICS may increase the risk of pneumonia and should be meticulously monitored in asthmatics.

Nicotine is the most toxic factor of tobacco. Genistein is a phytoestrogen and antioxidant that has numerous health benefits. The aim of this study is to evaluate the effects of genistein against toxic properties of nicotine to the pancreas of mice. For this purpose, 48 male mice were randomly assigned into six groups (n=8): normal control, nicotine control (2.5 mg/kg), genistein (25 and 50 mg/kg), and nicotine+genistein (25 and 50 mg/kg) treated groups. Various doses of genistein and genistein+nicotine were administered intraperitoneally to animals for 4 weeks. The weight of pancreas, total antioxidant capacity and nitrite oxide of serum, insulin levels, and the number and diameter of islets of Langerhans were investigated. Nicotine administration reduced significantly total antioxidant capacity, insulin, pancreas weight, and the number and diameter of islets of Langerhans and increased nitrite oxide in serum compared to the control normal group (P<0.05). Conversely, genistein and genistein+nicotine increased significantly insulin, total antioxidant capacity, and the number and diameter islets of Langerhans and decreased serum nitrite oxide compared to the nicotine control group. It seems that the genistein can improve pancreas damage following the nicotine administration.
