High prevalence of fatty liver and its association with metabolic syndrome among rural adults with chronic hepatitis C: Implications for primary healthcare.

BACKGROUND: Chronic hepatitis C (CHC) virus infection is a global health concern that is associated with significant liver-related morbidity and mortality. Owing to the inflammatory pathway, CHC can causefatty liver, liver cirrhosis, and liver cancer and is associated with cardiometabolic diseases, such as hypertension and diabetes. Fatty liver is associated with metabolic disorders, cardiovascular diseases, diabetes, and liver cancer. Hence, the early detection of fatty liver through noninvasive screening in adults with CHC is important in primary healthcare settings. This study aimed to explore the prevalence of fatty liver and its association with metabolic syndrome amongrural adults with CHC. METHODS: This was a series of cohort studies related to the elimination of the CHC burden around the western coastal Yunlin County, Taiwan, between August 2018 and July 2021. A cross-sectional study was conducted after hepatitis C virus RNA confirmation in a hepatitis C- endemic area. A gastrointestinal physician or radiologist assessed fatty liver by ultrasonography. Fatty liver was classified into four grades: normal, mild, moderate, and severe. Three liver enzyme biomarkers were identified. According to the Taiwan national standard, metabolic syndrome was defined based on the presence of three or more of the five abnormal biomarkers, including increased waist circumference, elevated blood pressure, elevated fasting blood glucose level, elevated triglyceride level, and low high-density lipoprotein cholesterol level. RESULTS: A total of 256 rural adults with CHC were enrolled. The mean age of the participants was 67.5 (standard deviation = 11.8) years, with a low educational level. High prevalence of fatty liver (79%), central obesity (54.3%), elevated blood pressure (55.5%),elevated fasting blood glucose (FBG) level (44.9%), and metabolic syndrome (37.9%) were observed.The results showed that adults with CHC with moderate to severe fatty liver were significantly associated with an increased risk of increased waist circumference (P < 0.001), increased blood pressure (P < 0.001), low high-density lipoprotein cholesterol level (P < 0.05), and elevated liver enzyme biomarker levels (all P < 0.05) after adjusting for age, sex, and educational level. Furthermore, adults with CHC with moderate to severe fatty liver were significantly associated with a greater risk of metabolic syndrome (odds ratio = 2.85, 95% confidence interval = 1.66 to 4.92). CONCLUSIONS: The findings demonstrate a high prevalence of fatty liver in rural adults with CHC, which is significantly associated with obesity, metabolic syndrome, and elevated liver biomarker levels. Clinicians and primary healthcare providers must encourage patients with CHC to receive antiviral therapy combined with weight loss management and lifestyle modification, allowing general improvements in their liver and cardiometabolic health.

The prevalence of chronic dehydration and associated with cardiometabolic risks among agriculture and aquaculture workers.

Background: Chronic dehydration is associated with complications and mortality in acute ischemic stroke patients. Prior literature indicates that farmers and fishery workers are commonly affected by cardiometabolic diseases and there is a need for early prevention of stroke. This study explores the prevalence of dehydration and the association of cardiometabolic risk profiles in agricultural and aquaculture workers. Methods: We conducted a community-based, cross-sectional study of agriculture and aquaculture workers in Yunlin County of Taiwan between August 1 and December 31, 2021. Data on demographic characteristics and health-related lifestyles were collected through one-on-one interviews using a questionnaire. The threshold for dehydration is defined as serum osmolality ≥295 mOsm/kg, and physiological biomarkers were collected from a collaborating hospital. Multivariable logistic regression analyses adjusted for demographic characteristics were performed to investigate the association between dehydration levels, cardiometabolic risks, and health-related behaviors. Results: A total of 962 Taiwanese agriculture and aquaculture workers who were predominantly women (65%) with a mean age of 64 years (SD = 13.8) were enrolled. The findings showed a high prevalence of dehydration (36%), metabolic syndrome (44.5%), abnormal waist circumference (64.4%), and abnormal blood pressure (68.5%). Multivariate logistic regression demonstrated that dehydration was significantly associated with metabolic syndrome (p < 0.001), 10-year stroke risk prediction (p < 0.001), and an unhealthy lifestyle (p < 0.001). Conclusion: The prevalence of chronic dehydration was higher in Taiwanese agriculture and aquaculture workers, which was significantly associated with cardiometabolic risks and unhealthy lifestyles.

Association between serum carcinoembryonic antigen and cardiometabolic risks: Implication for cardiometabolic prevention.

Background: Serum carcinoembryonic antigen (CEA) is a biomarker commonly used to detect colorectal cancer. CEA levels are affected by many factors, including cardiometabolic diseases, such as cardiovascular diseases (CVDs) and diabetes. Cardiometabolic diseases and cancer share a similar pathological inflammatory pathway, which correlates with an unhealthy lifestyle. Hence, establishing an adequate CEA cut-off value might be a valuable reference for developing precision healthcare programs for cardiometabolic disease prevention. This study aimed to investigate the association between cardiometabolic risks and serum CEA and the underlying factors. Methods: A community-based, cross-sectional study was conducted between March and December 2021 on the western coast of Taiwan. Lifestyle data were assessed using a structured questionnaire. The cardiometabolic biomarkers, serum CEA, urine malondialdehyde, and 1-hydroxypyrene were quantified by the central laboratory of the collaborating hospital. Chi-square and binary multivariable logistic regression implemented in R version 4.0.2 were used to identify factors defining the risk of high serum CEA levels. Results: A total of 6,295 adult residents without cancer-related diseases completed the study. The mean age was 48.6 (SD = 16.4) years, 56% were female, 32% had metabolic syndrome, and 23% and 10% had CVDs and diabetes, respectively. Multivariate logistic regression showed that age ≥ 65 years, male sex, alcohol consumption, smoking, infrequent use of dental floss, fewer remaining teeth, CVDs, diabetes, and oxidative stress were significantly associated with serum CEA ≥ 3 ng/mL. The discriminatory performance of the area under the receiver operating characteristic curve was 0.75 (0.73-0.76), showing that this model was suitable for distinguishing high CEA levels. Conclusion: Our findings highlight the importance of understanding cardiometabolic diseases, unhealthy lifestyles, and oxidative stress, which contribute to high serum CEA. This study demonstrates that CEA, a well-known tumor marker, can help the early detection and prevention of cardiometabolic diseases via personalized lifestyle modification.

Above-Standard Survival of Hepatocellular Carcinoma as the Final Outcome of Comprehensive Hepatology Care Programs in a Remote HCV-Endemic Area.

Early detection and prompt linkage to care are critical for hepatocellular carcinoma (HCC) care. Chang Gung Memorial Hospital (CGMH) Yunlin branch, a local hospital in a rural area, undertakes health checkup programs in addition to its routine clinical service. Patients with HCC are referred to CGMH Chiayi branch, a tertiary referral hospital, for treatment. This study enrolled 77 consecutive patients with newly diagnosed HCCs between 2017 and 2022, with a mean age of 65.7 ± 11.1 years. The screening group included HCC patients detected through health checkups, and those detected by routine clinical service served as the control group. Compared to the 24 patients in the control group, the 53 patients in the screening group had more cases with early stage cancer (Barcelona Clinic Liver Cancer or BCLC stage 0 + A 86.8% vs. 62.5%, p = 0.028), better liver reserve (albumin-bilirubin or ALBI grade I 77.3% vs. 50%, p = 0.031) and more prolonged survival (p = 0.036). The median survival rates of the 77 patients were >5 years, 3.3 years, and 0.5 years in the BCLC stages 0 + A, B, and C, respectively, which were above the expectations of the BCLC guideline 2022 for stages 0, A, and B. This study provides a model of HCC screening and referral to high-quality care in remote viral-hepatitis-endemic areas.

A novel nomogram for predicting cardiometabolic diseases from modifiable risks in middle-aged adults-implication for health education.

Background: Middle-aged adults often overlook critical modifiable risk factors that contribute to the emergence of cardiometabolic diseases (CMDs), including hypertension and diabetes. Many CMDs can be alleviated by addressing these modifiable risks. However, there has been insufficient research focused on rural adults with lower levels of health literacy in this regard. The aim of this study was to explore and develop an intuitive assessment tool for predicting cardiometabolic diseases (CMDs), which can be used for health education with adults of low health literacy. Methods: This was a community-based, cross-sectional study. A structured questionnaire on health-promoting habits, smoking, sleep, and physiological biomarkers was obtained via community health screening in the coastal region of Yunlin County, Taiwan. Multivariate logistic regression was used to screen for significant variables in the nomogram construction. Analysis with nonlinear restricted cubic spline was performed. Results: A total of 712 participants (60.9% females) aged 40-64 years, with middle school level or lower education, were included. The average age was 55.6 years (SD=7.3), and 220 individuals (31%) had CMDs. Multivariate logistic regression analysis revealed that age, lower scores of vegetables, fruit, water, and exercise (VFWE), smoking history, sleep deprivation, and being overweight were significantly associated with CMDs. The model incorporating these modifiable risk factors demonstrated good discriminatory ability, as indicated by an area under the receiver operating characteristic curve of 0.75 (0.73-0.76). A predictive nomogram was developed that presented modifiable risk factors in a simple graphical format to facilitate the prediction of CMDs. Conclusions: This study highlights a high prevalence of CMDs among middle-aged adults, along with the disregard for important risk factors that could be modified. The developed nomogram could be a practical and effective tool for community health education to enhance health literacy and prevent the progression of CMDs.

Health Inequality among Fishery Workers during Climate Change: A National Population-Based and Retrospective Longitudinal Cohort Study.

Background: Owing to specific working environments, it is important to attain sustainable development goals for the health of fishery workers during climate change. Fishery workers have a hazardous working environment, leading to specific injuries and fatal events. However, limited studies have investigated the health status of fishery workers through long-term longitudinal follow-up and compared it with that of farmers and employed workers with similar socioeconomic status. Methods: The Longitudinal Health Insurance Database 2000, a subset of the Taiwan National Health Insurance Research Database was used for this retrospective cohort study. Only fishery workers, farmers, and employed workers were included. Based on the majority of causes of death and related diseases, participants newly diagnosed with 18 diseases, classified into cardiometabolic diseases, mental illness, chronic kidney disease, infection, and malignancy, were included. Participants with an old diagnosis of these diseases were excluded. All included participants were followed up from 1 July 2000 to the diagnosis and withdrawal date, or 31 December 2012, whichever occurred first. Due to the substantial difference in the baseline demographics, we executed a cohort study with propensity score-matched and applied the Cox model to explore the participants' health status. Results: After matching, there were negligible differences in the baseline demographics of fishery workers, farmers, and employed workers. Compared to farmers and employed workers, fishery workers were more frequently diagnosed with 11 and 14 diseases, respectively, such as hypertension (hazard ratio [HR]: 1.11, p < 0.01), diabetes (HR: 1.21, p < 0.001), dyslipidemia (HR: 1.18, p < 0.001), depression (HR: 1.38, p < 0.001), peptic ulcer (HR: 1.17, p < 0.001), chronic viral hepatitis (HR: 2.06, p < 0.001), hepatocellular carcinoma (HR: 1.67, p < 0.001), and total malignancy (HR: 1.26, p < 0.001). Conclusions: Compared to farmers and employed workers, fishery workers were more impacted by cardiometabolic diseases, mental illness, infection, and malignancy. Therefore, it is imperative to specifically focus on health policies for fishery workers, such as providing curable antiviral treatment and initiating culture-tailored health promotion programs, to mitigate health inequality.

Application of a Novel Biosensor for Salivary Conductivity in Detecting Chronic Kidney Disease.

The prevalence of chronic kidney disease (CKD) is increasing, and it brings an enormous healthcare burden. The traditional measurement of kidney function needs invasive blood tests, which hinders the early detection and causes low awareness of CKD. We recently designed a device with miniaturized coplanar biosensing probes for measuring salivary conductivity at an extremely low volume (50 µL). Our preliminary data discovered that the salivary conductivity was significantly higher in the CKD patients. This cross-sectional study aims to validate the relationship between salivary conductivity and kidney function, represented by the estimated glomerular filtration rate (eGFR). We enrolled 214 adult participants with a mean age of 63.96 ± 13.53 years, of whom 33.2% were male. The prevalence rate of CKD, defined as eGFR < 60 mL/min/1.73 m2, is 11.2% in our study. By multivariate linear regression analyses, we found that salivary conductivity was positively related to age and fasting glucose but negatively associated with eGFR. We further divided subjects into low, medium, and high groups according to the tertials of salivary conductivity levels. There was a significant trend for an increment of CKD patients from low to high salivary conductivity groups (4.2% vs. 12.5% vs. 16.9%, p for trend: 0.016). The receiver operating characteristic (ROC) curves disclosed an excellent performance by using salivary conductivity combined with age, gender, and body weight to diagnose CKD (AUC equal to 0.8). The adjusted odds ratio of CKD is 2.66 (95% CI, 1.10−6.46) in subjects with high salivary conductivity levels. Overall, salivary conductivity can serve as a good surrogate marker of kidney function; this real-time, non-invasive, and easy-to-use portable biosensing device may be a reliable tool for screening CKD.

Factors Associated with Urinary 1-Hydroxypyrene and Malondialdehyde among Adults near a Petrochemical Factory: Implications for Sex and Lifestyle Modification.

BACKGROUND: The association between the biomarkers of environmental exposure, oxidative stress, and health-related behaviors in community residents living in an endemic viral hepatitis area and near petrochemical industrial complexes remains unclear. From a health promotion perspective, healthcare providers must know what to do for residents concerned about their health and living environment, especially for individual-level and modifiable risk factors. Therefore, we aimed to explore the factors associated with urinary 1-hydroxypyrene (1-OHP) and malondialdehyde (MDA). METHODS: A community-based, cross-sectional study was conducted between July 2018 and February 2019 in western coastal Yunlin County, Taiwan. All participants lived within a 10 km radius of a large petrochemical complex and did not work in the factory. This study was conducted with the local hospital through annual community health screening. Biological samples were collected and biomarkers determined and quantified in the central laboratory of the collaborating hospital. RESULTS: A total of 6335 adult residents completed the study. The mean age was 47.7 (SD = 16) years. Out of the total population, 56.4% were female, 30.1% had metabolic syndrome (MetS), and 16.8% and 14.3% had hepatitis B virus antigen (HBsAg) and hepatitis C virus antibody (anti-HCV) positivity, respectively. The median 1-OHP and MDA level was 0.11 and 0.9 µg/g creatinine with an interquartile range of 0.07-0.18, and 0.4-1.5, respectively. The MDA levels correlated with specific diseases. The multivariable ordinal logistic regression model revealed that female sex, smoking, betel nut use, HBsAg, and anti-HCV positivity were associated with higher 1-OHP levels. In men, MetS was associated with higher 1-OHP levels and regular exercise with lower 1-OHP levels. High MDA levels were associated with smoking, betel nut users, HBsAg, and anti-HCV positivity. CONCLUSIONS: The findings highlight the importance of initiating individualized health promotion programs for residents near petrochemical factories, especially for adults with substance-use and cardiometabolic risk factors. Furthermore, it is crucial to provide further treatment to patients with viral hepatitis.

The health impact of an innovative summer camp for older adults: a pilot study using an interdisciplinary collaborative approach.

BACKGROUND: Healthy aging with dignity and aging in place are important for Taiwanese individuals. Although Taiwan did not experience COVID-19 outbreaks prior to May 2021, many older adults have been encouraged to stay at home since the beginning of the global pandemic in January 2020. Such shelter-in-place recommendations have resulted in significant lifestyle changes, limiting activities associated with aging with dignity such as exercise and community engagement. Few studies have explored how to promote or maintain holistic health practices and physical fitness in older adults residing in rural communities during the COVID-19 pandemic. This pilot study aimed to establish an interdisciplinary collaboration with community care workers (CCWs) and evaluate the impact of an innovative summer camp (ISC) program for older adults residing in rural areas. METHODS: A quasi-experimental pre-post-test design with an interdisciplinary collaborative approach was implemented. The ISC program was based on a standardized protocol of modified Baduanjin exercise combined with three recreational breathing games. Participants were recruited from three community centers around the western coastal region of Yunlin County between June and August 2020. The ISC program was designed and executed by a nurse-led health promotion research team that collaborated with trained CCWs for 90 min per day, five days per week, for 12 weeks. Participants and CCWs wore facemasks during all activities. Paired t-test was used to measure changes in physical biomarkers, pulmonary lung function, and health-related fitness changes. RESULTS: Sixty-eight participants completed the ISC program. The ISC program significantly improved the participants' physiological biomarkers and health-related fitness, including reduced body weight, waistline, and systolic blood pressure, and increased forced vital capacity, biceps arm flexion, and ability to sit and stand from a chair, step with a knee up in situ, and stand on one foot with eyes open. Most participants reported that they felt happy, satisfied, and hoped that this program would be continued in their community center. CONCLUSIONS: This interdisciplinary, collaborative ISC program improved physical biomarkers and health-related fitness in older adults. Despite limitations, results strongly suggested that primary healthcare providers and CCWs can employ the described ISC program to promote wellness in older adults.

Village-to-village screening for hepatitis B and C using quantitative HBsAg and anti-HCV testing with reflex HCV core antigen tests in the remote communities of a resource-rich setting: a population-based prospective cohort study.

OBJECTIVES: Community-based screening for hepatitis B virus (HBV) and hepatitis C virus (HCV) is essential for hepatitis elimination. This study attempted to increase screening accessibility and efficacy by using alternative tools. DESIGN: Population-based prospective cohort study. SETTING: Hepatitis elimination program at Yunlin County, Taiwan. PARTICIPANTS: All 4552 individuals participated in 60 screening sessions of a community-based HBV and HCV screening project in five rural townships with approximately 95 000 inhabitants in central-western Taiwan. INTERVENTIONS: To increase accessibility, 60 outreach screening sessions were conducted in 41 disseminative sites. Quantitative HBV surface antigen (qHBsAg) and anti-HCV testing with reflex HCV core antigen (HCV Ag) tests were employed as alternative screening tools. MAIN OUTCOME MEASURES: Calculate village-specific prevalence of HBsAg, anti-HCV and HCV Ag and establish patient allocation strategies according to levels of qHBsAg HCV Ag and alanine aminotransferase (ALT). RESULTS: Of 4552 participants, 553, 697 and 290 were positive for HBsAg, anti-HCV and HCV Ag, respectively; 75 of them had both HBsAg and anti-HCV positivity. The average (range) number of participants in each screening session was 98 (31-150). The prevalence rates (range) of HBsAg, anti-HCV and HCV Ag were 12.1% (4.3%-19.4%), 15.3% (2.6%-52.3%) and 6.4% (0%-30.2%), respectively. The HCV Ag positivity rate among anti-HCV-positive participants was 42% (0%-100%). Using cut-off values of >200 IU/mL for qHBsAg, >3 fmol/L for HCV Ag and >40 IU/mL for ALT as criteria for patient referral, we noted an 80.2% reduction in referral burden. Three villages had high anti-HCV prevalences of 52.3%, 53.8% and 63.4% with corresponding viraemic prevalences of 23.2%, 30.1% and 22% and thus constituted newly identified HCV-hyperendemic villages. CONCLUSION: Outreach hepatitis screening increases accessibility for residents in rural communities. Screening HBV and HCV through qHBsAg and HCV Ag tests provides information concerning viral activities, which might be conducive to precise patient allocation in remote communities.

Lung function impairment and cardiometabolic risks among rural adults: implication for an aging society.

BACKGROUND: Early detection and prevention of cardiometabolic risk factors in an increasingly aging society are a global public health concern. Maintaining adequate lung function is important for healthy aging. Few studies exist on lung function impairment and decline in primary healthcare settings, especially among rural adults with cardiometabolic risks. This study aimed to explore the prevalence of impaired lung function and its association with cardiometabolic risks among rural adults. METHODS: A community-based, cross-sectional study was conducted between March and December 2019 in western coastal Yunlin County, Taiwan. The lung function test was measured by spirometry, based on the American Thoracic Society recommendations. Three lung function parameters were obstructive lung impairment, restrictive lung impairment, and mixed lung impairment. Restrictive, obstructive, and mixed type lung function was categorized as impaired. Cardiometabolic risk factors and metabolic syndrome were based on the national standard and include five abnormal biomarkers, including abdominal obesity, blood pressure, fasting plasma glucose, triglycerides, and decreased high-density cholesterol levels. RESULTS: The median age of the 1653 (92.9%) participants with complete data was 66 years (interquartile range: 55 to 75 years). The prevalence of impaired lung function was 37%, including 31.7% restrictive, 2.5% obstructive, and 2.7% mixed type. Adults with impaired lung function (86% restrictive type) engaged more in smoking and betel nut chewing, ate fewer vegetables and fruit, and drank less water compared to the normal lung function group. After adjusting for potential confounding variables, multivariate logistic regression analysis showed that cardiometabolic risk factors were independently associated with restrictive lung impairment, while cigarette smoking (OR = 2.27, 95% CI = 1.14-4.53) and betel nut chewing (OR = 2.33, 95% CI = 1.09-5.01) were significantly associated with the obstructive type of lung impairment. CONCLUSIONS: A high prevalence of restrictive lung impairment, cardiometabolic risks, and unhealthy lifestyles among rural adults were found in this study. For adults with cardiometabolic risks in rural areas, initiating lifestyle modifications with culture-tailored programs to improve lung function should be an important issue for clinicians and primary healthcare providers.

Usefulness of quantitative hepatitis B surface antigen testing in hepatitis B community-based screening.

BACKGROUND/PURPOSE: Low viral load (LVL) of hepatitis B virus (HBV) is a predictor of chronic HBV infection. However, the usefulness of quantitative hepatitis B surface antigen (qHBsAg) in predicting LVL in community-based screening has not been well studied. We aimed to measure the prevalence of LVL in HBV carriers and validate the efficacy of qHBsAg in predicting LVL. METHODS: This community-based screening study was conducted in Taiwan. HBV DNA was assayed in HBsAg carriers. Participants were randomized to training and validation sets to determine the ability of qHBsAg to predict LVL. Receiver operating characteristic curves were used to identify the best cutoff values in the training set. RESULTS: Among the 2919 participants, 359 (12.2%) were HBsAg carriers. There were 132 and 137 carriers in the training and validation sets, respectively. Significant correlations were found between qHBsAg and HBV DNA in both training and validation sets. Thirty and 29 participants with qHBsAg <8 IU/mL in the training and validation sets, respectively, had LVL. Using 8 IU/mL as the cutoff, negative predictive value (NPV) of qHBsAg for HBV DNA levels >2000 IU/mL was 100%. The best cutoff level of qHBsAg to predict HBV LVL was 200 IU/mL, with a sensitivity, specificity, and accuracy of 75.0%, 76.1%, and 75.8%, respectively, in the training set. The positive predictive value and NPV were 70.0% and 77.9%, respectively, in the validation set. CONCLUSION: Approximately 60% of HBsAg carriers had HBV LVL, and qHBsAg <8 IU/mL accurately predicts LVL. This quantitative test provides additional information for community-based screening.

Feasibility of anti-HCV reflex HCV Ag screening strategy in an HCV endemic community.

BACKGROUND/PURPOSE: The HCV core antigen (HCV Ag) assay displays high sensitivity and strong correlation with HCV RNA. However, the feasibility of anti-HCV reflex HCV Ag screening in a community-wide setting is rarely discussed. METHODS: We performed a two-phase community-based hepatitis C screen in an HCV-prone area of central Taiwan. During the training phase, all participants were test for anti-HCV, HCV Ag and HCV RNA to validate sensitivity, specificity, and accuracy of HCV Ag. During the validation phase, an anti-HCV reflex HCV Ag screen was conducted based on the results of training phase. Outcomes of the study were presented as positive and negative predictive values (PPV and NPV). RESULTS: Of 935 training phase participants, the rate of positive anti-HCV and HCV Ag were 175 (18.7%) and 78 (8.3%), respectively. Test sensitivity, specificity, and accuracy of HCV Ag were 97.1%, 98.6%, and 97.8%, respectively. During validation phase, only anti-HCV-positive serum samples were tested for HCV Ag. Of 1932 participant, 285 (14.8%) were anti-HCV-positive. 133 (46.7%) of the 285 anti-HCV-positive samples were HCV Ag-positive. PPV and NPV were 98.4% and 99.3%, respectively. Across the entire participant sample, a significant linear correlation between HCV Ag and HCV RNA concentration was noted (r2 = 0.93, p-value<0.001) following log-log transformation. CONCLUSION: Anti-HCV reflex HCV Ag screening is a feasible strategy for aiding HCV-prone communities.

The effectiveness of an oral hygiene program combined with health-promoting counseling for rural adults with cardiometabolic risks: A quasi-experimental design.

AIM: The aim of this study was to explore the effectiveness of an oral hygiene program combined with home-phone health promoting counseling for rural adults with metabolic syndrome. BACKGROUND: Metabolic syndrome is an important risk factor for cardiometabolic diseases. Evidence indicates that the poor oral hygiene and unhealthy lifestyles are closely related to metabolic syndrome. METHODS: A prospective quasi-experimental design involved a total of 136 community adults, with metabolic syndrome living in two rural townships, were clustered and conveniently assigned to intervention and control group between June 2017 and December 2018. The primary outcome was the change in cardiometabolic biomarkers. The secondary outcome comprised changes in the health-promoting behaviors. The intervention effect was assessed using a generalized estimating equation model. RESULTS: There were 80 and 56 participants in the intervention and control group, respectively. The mean age was 56 years and ranged from 33 to 70 years. The intervention group exhibited a greater improvement in body mass index (P < 0.01), waist circumference (P < 0.05), body fat percentage (P < 0.05), triglyceride level (P < 0.05), use of dental floss (P < 0.05), regular tooth scaling (P < 0.05), physical activity (P < 0.001), and total score of health-promoting behaviors (P < 0.001) than the control group. CONCLUSION: This study supports the use of an oral hygiene program combined with home-phone counseling, which offers more advantages than its counterpart. Considering the global epidemic of cardiometabolic diseases, this is a community health nursing model worth to replicate and evaluate. Further study should consider innovative strategies to improve the awareness and adoption of a healthy lifestyle in residents with cardiometabolic risks.

Liver Health Literacy and Health Status Among Adults With Hepatitis C: Implications for the Nursing Profession as Part of the 2030 Global Elimination Goal.

PURPOSE: To explore the prevalence of hepatitis C virus (HCV) infection as well as the levels of liver health literacy and association with the health status of people with HCV through the nurse-led community health development goal of global elimination. METHODS: A community-based, cross-sectional study was conducted between July 2018 and June 2019 in coastal Western Yunlin County, Taiwan. This study was conducted at five townships, and serum HCV antibody (anti-HCV) screening was used for the identification of potentially infected people by a collaborating local hospital. RESULTS: Of the 1,963 adults from rural areas enrolled in this study, 321 (16.4%) were anti-HCV positive, 237 (73.8%) reported that they were unaware of their HCV positivity, and none of them were provided information on direct-acting antiviral agent therapy. The levels of anti-HCV positivity were higher among female patients (p < .05), elderly people (p < .001), those with a low education level (p < .001), and those from the Sihu Township within Yunlin County (p < .001). Participants with anti-HCV positivity tended to have lower intakes of vegetables (p < .01) and fruit (p < .05), a greater number of comorbidities (p < .05), as well as a greater incidence of abnormal liver (p < .001) and renal function (p < .001) compared to those with anti-HCV negativity. Multivariable linear regression analysis showed that the presence of HCV infection and a greater number of metabolic syndrome components were associated with poor liver and renal function. CONCLUSIONS: These findings showed a high prevalence of HCV infection among adults living in rural areas, who had low literacy levels on hepatitis, unhealthy lifestyles, and abnormal liver and renal function. CLINICAL RELEVANCE: Clinicians and primary healthcare providers should initiate efforts to increase the levels of liver health literacy by increasing the accessibility to infection confirmation tests and reducing the number of barriers to the reception of antiviral treatment.

Effect of HCV treatment response on insulin resistance: A systematic review and meta-analysis.

Sustained virological response (SVR) in hepatitis C virus (HCV) patients treated with pegylated interferon α-2a and ribavirin is associated with reduced insulin resistance (IR), measured as a reduction of homeostasis model assessment (HOMA) scores after 24 weeks of therapy, and reduced fasting serum insulin and serum glucose levels. The present meta-analysis aimed to evaluate the effect of HCV treatment response on IR in HCV patients who achieved SVR and those who did not (non-SVR) after receiving interferon (IFN)-based therapy. The PubMed, Cochrane and Embase databases were searched using combinations of the following search terms: 'HCV', 'hepatitis C', 'interferon', 'antiviral', 'treatment response' and 'insulin resistance'. The incidence of IR, HOMA-IR and HOMA-ß, as well as fasting glucose and fasting insulin levels, were summarized in terms of basal values and values after the end of treatment for each study. A total of 8 studies were included in the final analysis. There was no significant difference in the reduction in IR between the SVR and non-SVR groups (odds ratio, 0.995; 95% CI=0.613-1.616; P=0.984). However, the SVR group had a significantly higher mean reduction in HOMA-IR (difference in means=-0.485; 95%CI=-0.713 to -0.256; P<0.001) and HOMA-ß (difference in means=-15.448; 95%CI=-23.326 to -7.570; P<0.001) compared to the non-SVR group. In conclusion, HCV patients who achieved SVR after IFN-based therapy exhibited improvement in HOMA-IR and HOMA-ß. The present results suggest that clinical management of IR and serum glucose levels may be an important way to impact the therapeutic response in HCV patients.

Comparison of Compliance and Efficacy of Pegylated Interferon α-2a and α-2b in Adults with Chronic Hepatitis C.

This study compares treatment completion rates and outcomes in hepatitis C virus (HCV) patients between those aged <60 and ≥60 years receiving pegylated interferon (PEG-IFN) α-2a or α-2b combined with ribavirin. No significant differences were found in treatment completion rates and virological responses between age-stratified patients or between genotype-stratified patients receiving PEG-IFN α-2a versus PEG-IFN α-2b. Significantly more patients ≥60 years of receiving PEG-IFN α-2b exhibited an early virological response compared to those receiving PEG-IFN α-2a (P = 0.002); for patients <60 years of age, treatment outcomes were similar between the 2 groups. More liver fibrosis was observed in patients with HCV of genotype 1 than in those with genotypes 2 or 3. Mean changes in pre- and post-treatment fibrosis variables (bilirubin, platelet count, liver enzymes, FIB-4, and APRI) in HCV genotype 1 patients were greater in those receiving PEG-IFN α-2b than in those receiving PEG-IFN α-2a. Significant differences were not observed between age- and HCV genotype-stratified patients receiving PEG-IFN α-2a and -α-2b, but α-2b appears to have a modest efficacy advantage over α-2b, particularly in male HCV patients ≥60 years of age.

Association between hepatitis C virus infection and osteoporotic fracture risk among postmenopausal women: a cross-sectional investigation in Taiwan.

PURPOSE: Early low bone mass is a risk factor for osteoporotic fractures associated with multiple factors, including menopause and chronic liver diseases. Hepatitis C virus (HCV) also plays a major role in chronic liver disease and has many extrahepatic consequences, such as decreased bone mineral density (BMD). This study aimed to examine the hypothesis that HCV seropositivity is independently associated with menopausal BMD loss. METHODS: This community-based, cross-sectional study was based in two rural townships in Yunlin County, Taiwan. A total of 636 menopausal women aged 45-80 years who underwent annual health checks were included. Viral markers of HCV, dual-energy X-ray absorptiometry and fracture risk assessment tool (FRAX) scores were measured. Logistic regression analysis was performed to assess the association between various predictors and the presence of low BMD. RESULTS: The participants (median age: 65 years) had a HCV seropositivity rate of 32.2%. BMD was significantly lower in the HCV-seropositive participants in different anatomic locations than in the seronegative individuals (lumbar spine: -1.5 vs -1.1; total hip: -0.9 vs -0.6; femoral neck: -1.2 vs -1.0; p<0.05). HCV-seropositive subjects had higher rates of major osteoporotic fractures (11.3%±7.6%vs 9.0±6.8%; p<0.001) and hip fractures (3.4%±4.7%vs 2.3±4.9%; p=0.006) and a higher risk of lower BMD (osteopenia and osteoporosis) based on a multivariable regression analysis (adjusted OR: 1.8; 95% CI 1.16 to 2.81; p=0.009). CONCLUSIONS: HCV infection may be an independent risk factor for menopausal BMD loss and fractures predicted by FRAX.

The association between smoking and cardiometabolic risk among male adults with disabilities in Taiwan.

BACKGROUND: Individuals with disabilities have health needs similar to the general population. Smoking and metabolic syndrome have emerged as major cardiovascular risks that contribute to systemic inflammation and mortality. However, few studies have focused on the association between smoking and cardiometabolic risks in adult men with disabilities. AIMS: This study explored the prevalence of smoking and its association with cardiometabolic risk and associated factors among male adults with disabilities. METHODS: This study was part of a nurse-led health-promotion program designed to examine the health needs in health programs for adults with disabilities. A community-based, cross-sectional study was conducted between July 2013-December 2014, in Chiayi County, Taiwan. RESULTS: Of the total of 964 male participants enrolled in this study, 874 (90.7%) participants had complete data sets. The prevalence of cigarette smoking and metabolic syndrome were 42%, and 33.3%, respectively. More than half (62.7%) had high blood pressure and 43.5% had central obesity. Compared with non-smokers, smokers tended to engage in less frequent regular exercise ( p<0.001), eat fewer vegetables and fruit ( p<0.05), and drink less water ( p<0.05). After adjusting for potential confounding variables, multivariable logistic regression analysis showed that smoking was an independent factor for cardiometabolic risk. CONCLUSION: The present findings show a high prevalence of cigarette smoking, unhealthy lifestyle, and cardiometabolic risk among adult men with disabilities. Clinicians and primary healthcare providers should reduce the consequences thereof by initiating innovative health promotion programs.
