Sex differences in relationships between metabolic syndrome components and factors associated with health-related quality of life in middle-aged adults living in the community: a cross-sectional study in Taiwan.

BACKGROUND: Metabolic syndrome (MetS) is a widespread condition with important effects on public health, in general. There is a lack of relevant research on possible sex differences in the relationship between MetS and health-related quality of life (HRQoL) and also the sex differences in factors associated with HRQoL. The aims of this study were to identify: 1) whether women exhibit greater negative impacts on physical domain HRQoL from MetS compared with men; 2) whether women exhibit greater mental domain impacts compared with men; and 3) whether factors associated with HRQoL scores are different for men and women. METHODS: This cross-sectional study was conducted in Taipei, Taiwan. Using random sampling, a total of 906 participants aged 35-55 years were recruited. MetS was defined according to the MetS criteria for the Taiwanese population, and HRQoL were assessed using physical component summary (PCS) and mental component summary (MCS) scores of the Short Form Health Survey (SF-36), Taiwan version. Demographics, physical activity, medical history, and blood tests as covariates were recorded and checked. The associations were assessed by multiple linear regression. RESULTS: After adjusting for covariates, women but not men with more components of MetS had significantly lower PCS scores (ß = - 0.542, p = 0.036). The number of components of MetS was not a significant factor in MCS score differences between the sexes. Furthermore, there were sex differences regarding age, education level, physical activity, and smoking status in association with PCS scores. For MCS scores, sex differences were found in education level, marital status, and habits of smoking and alcohol consumption. CONCLUSIONS: There were sex differences in the relationships between metabolic syndrome components and factors associated with HRQoL among middle-aged adults living in the community in Taiwan. Further research should be conducted to investigate mechanisms of these sex differences.

Infrared thermography in the evaluation of meibomian gland dysfunction.

BACKGROUND/PURPOSE: To evaluate meibomian gland dysfunction (MGD) by infrared thermography. METHODS: An observational study was conducted at the Department of Ophthalmology, Far Eastern Memorial Hospital, New Taipei City, Taiwan. Participants included 89 MGD patients (30 in Grade 1, 49 in Grade 2, and 10 in Grade 3) and 65 controls. The close-eye thermographic images of the eyelid were obtained noninvasively by infrared thermography. Temperatures at 8 regions of interest (ROIs) of the eyelid margin and a reference temperature at the center of the upper eyelid were measured. The temperature ratio was defined as the temperature of ROI divided by the reference temperature. RESULTS: Eyelid margin temperature measured by infrared thermography increased from temporal side (ROI 1) to the nasal side (ROI 8) of the eye in both MGD patients and control groups. The temperature ratios were significantly higher in MGD participants than in controls, especially at ROI 8. CONCLUSION: The eyelid margin temperature measured by infrared thermography was higher in MGD participants. Further development of this infrared thermography system may become a rapid and non-invasive tool for MGD screening.

Baicalein, a Component of Scutellaria baicalensis, Attenuates Kidney Injury Induced by Myocardial Ischemia and Reperfusion.

Acute kidney injury is a common and severe complication of acute myocardial infarction and cardiac surgery. It results in increased mortality, morbidity, and duration of hospitalization. Baicalein is a component of the root of Scutellaria baicalensis, which has traditionally been used to treat cardiovascular and liver diseases in Asia. In this study, we investigated whether baicalein can attenuate kidney injury induced by myocardial ischemia and reperfusion in rats. Myocardial ischemia and reperfusion, induced by a 40-minute occlusion and a 3-hour reperfusion of the left anterior descending coronary artery, significantly increased blood urea nitrogen and creatinine levels in addition to causing histological changes in the kidneys. Kidney apoptosis was also significantly increased. Furthermore, myocardial ischemia and reperfusion significantly increased the serum levels of tumor necrosis factor-α, interleukin-1, and interleukin-6 as well as the tumor necrosis factor-α levels in the kidneys. Intravenous pretreatment with baicalein (in doses of 3, 10, or 30 mg/kg), however, significantly reduced the increases in the creatinine level, renal histological damage, and apoptosis induced by myocardial ischemia and reperfusion. In addition, the increases in the serum levels of tumor necrosis factor-α, interleukin-1, and interleukin-6, and of tumor necrosis factor-α in the kidneys were significantly reduced. Western blot analysis revealed that baicalein significantly increased Bcl-2 and reduced Bax in the kidneys. The phosphorylation of Akt and extracellular signal-regulated kinases 1 and 2 was also significantly increased. In conclusion, baicalein significantly attenuates kidney injury induced by myocardial ischemia and reperfusion. The underlying mechanisms might be related to the inhibition of apoptosis, possibly through the reduction of tumor necrosis factor-α production, the modulation of Bcl-2 and Bax, and the activation of Akt and extracellular signal-regulated kinases 1 and 2.

The epidemiology and prognostic factors of mortality in critically ill children with acute kidney injury in Taiwan.

The incidence of acute kidney injury (AKI) in critically ill children varies among countries. Here we used claims data from the Taiwanese National Health Insurance program from 2006 to 2010 to investigate the epidemiological features and identify factors that predispose individuals to developing AKI and mortality in critically ill children with AKI. Of 60,338 children in this nationwide cohort, AKI was identified in 850, yielding an average incidence rate of 1.4%. Significant independent risk factors for AKI were the use of extracorporeal membrane oxygenation, mechanical ventilation or vasopressors, intrinsic renal diseases, sepsis, and age more than 1 year. Overall, of the AKI cases, 46.5% were due to sepsis, 36.1% underwent renal replacement therapy, and the mortality rate was 44.2%. Multivariate analysis showed that the use of vasopressors, mechanical ventilation, and hemato-oncological disorders were independent predictors of mortality in AKI patients. Thirty-two of the 474 patients who survived had progression to chronic kidney disease or end-stage renal disease. Thus, although not common, AKI in critically ill children still has a high mortality rate associated with a variety of factors. Long-term close follow-up to prevent progressive chronic kidney disease in survivors of critical illnesses with AKI is mandatory.

Brief left ventricular pressure overload reduces myocardial apoptosis.

BACKGROUND: Both apoptosis and necrosis contribute to cell death after myocardial ischemia and reperfusion. We previously reported that brief left ventricular pressure overload (LVPO) decreased myocardial infarct (MI) size. In this study, we investigated whether brief pressure overload reduces apoptosis and the mechanisms involved. MATERIALS AND METHODS: MI was induced by a 40-min occlusion of the left anterior descending coronary artery and 3-h reperfusion in male anesthetized Sprague-Dawley rats. Brief LVPO was achieved by two 10-min partial snarings of the ascending aorta, raising the systolic left ventricular pressure 50% above the baseline value. Ischemic preconditioning was elicited by two 10-min coronary artery occlusions and 10-min reperfusions. RESULTS: Brief LVPO and ischemic preconditioning significantly decreased MI size (P < 0.001). Brief pressure overload significantly reduced myocardial apoptosis, as evidenced by the decrease in the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling-positive nuclei (P < 0.001), little or no DNA laddering, and reduced caspase-3 activation (P < 0.01). Moreover, brief pressure overload significantly increased Bcl-2 (P < 0.001) and decreased Bax (P < 0.001) and p53 (P < 0.01). Akt phosphorylation was significantly increased by brief pressure overload (P < 0.001), whereas c-Jun N-terminal kinase phosphorylation was significantly decreased (P < 0.001). Hemodynamics, area at risk, and mortality did not differ significantly among groups. CONCLUSIONS: Brief left LVPO significantly reduces myocardial apoptosis. The underlying mechanisms might be related to modulation of Bcl-2 and Bax, inhibition of p53, increased Akt phosphorylation, and suppressed c-Jun N-terminal kinase phosphorylation.

The role of adenosine in preconditioning by brief pressure overload in rats.

BACKGROUND/PURPOSE: Brief pressure overload of the left ventricle reduced myocardial infarct (MI) size in rabbits has been previously reported. Its effects in other species are not known. This study investigates effects of pressure overload and the role of adenosine in rats in this study. METHODS: MI was induced by 40-minute occlusion of the left anterior descending coronary artery followed by 3-hour reperfusion. MI size was determined by triphenyl tetrazolium chloride staining. Brief pressure overload was induced by two 10-minute episodes of partial snaring of the ascending aorta. Systolic left ventricular pressure was raised 50% above the baseline value. Ischemic preconditioning was elicited by two 10-minute coronary artery occlusions. RESULTS: The MI size (mean ± standard deviation), expressed as percentage of area at risk, was significantly reduced in the pressure overload group as well as in the ischemic preconditioning group (17.4 ± 3.0% and 18.2 ± 1.5% vs. 26.6 ± 2.4% in the control group, p < 0.001). Pretreatment with 8-(p-sulfophenyl)-theophylline (SPT), an inhibitor of adenosine receptors, did not significantly limit the protection by pressure overload and ischemic preconditioning (18.3 ± 1.5% and 18.2 ± 2.0%, respectively, p < 0.001). SPT itself did not affect the extent of infarct (25.4 ± 2.0%). The hemodynamics, area at risk and mortality were not significantly different among all groups of animals. CONCLUSION: Brief pressure overload of the left ventricle preconditioned rat myocardium against infarction. Because SPT did not significantly alter MI size reduction, our results did not support a role of adenosine in preconditioning by pressure overload in rats.

Urban-rural disparity of generics prescription in Taiwan: the example of dihydropyridine derivatives.

The aim of the current study was to investigate the urban-rural disparity of prescribing generics, which were usually cheaper than branded drugs, within the universal health insurance system in Taiwan. Data sources were the cohort datasets of National Health Insurance Research Database with claims data in 2010. The generic prescribing ratios of dihydropyridine (DHP) derivatives (the proportion of DHP prescribed as generics to all prescribed DHP) of medical facilities were examined against the urbanization levels of the clinic location. Among the total 21,606,914 defined daily doses of DHP, 35.7% belonged to generics. The aggregate generic prescribing ratio rose from 6.7% at academic medical centers to 15.3% at regional hospitals, 29.4% at community hospital, and 66.1% at physician clinics. Among physician clinics, the generic prescribing ratio in urban areas was 63.9 ± 41.0% (mean ± standard deviation), lower than that in suburban (69.6 ± 38.7%) and in rural (74.1% ± 35.3%). After adjusting the related factors in the linear regression model, generic prescribing ratios of suburban and rural clinics were significantly higher than those of urban clinics (ß = 0.043 and 0.077; P = 0.024 and 0.008, resp.). The generic prescribing ratio of the most popular antihypertensive agents at a clinic was reversely associated with the urbanization level.

Understanding the factors associated with nurse employment in clinics: Experiences in Taiwan.

BACKGROUND: The shortage and distribution of nurses affect healthcare access in aging societies. Limited research has explored the nursing workforce in clinics, which is vital for healthcare delivery. This study aimed to investigate the shortage and distribution of nurses in clinics in Taiwan, considering geographical, institutional, and specialty variations. METHODS: We conducted a cross-sectional analysis of the national nursing workforce in Western medicine clinics in Taiwan using open government data. The nursing practice rate (NPR) was calculated. The ratio of clinics employing nurses (RCN) was determined by calculating the percentage of clinics with nurses in each category. A logistic regression model was fitted to examine the factors associated with nurse employment, including urbanization level and different specialty clinics. Adjusted odds ratios (OR) and 95% CIs were calculated. RESULTS: The study revealed an overall NPR as low as 59.1%, and a decreasing trend with age. Among the 11 706 clinics in the study, nearly a quarter did not employ nurses, with an overall RCN of 72.3%. Urbanization level and clinic specialty were associated with nurse employment ( p < 0.05). After adjusting for urbanization level, the fitted regression model identified the top three specialties as plastic surgery (OR = 11.37, RCN = 96.8%), internal medicine (OR = 1.94, RCN = 84.1%), and orthopedics (OR = 1.89, RCN = 83.6%), while the bottom three were otolaryngology (OR = 0.59, RCN = 61.5%), psychiatry (OR = 0.49, RCN = 57.1%), and rehabilitation medicine (OR = 0.30, RCN = 45.2%). Nurses were more likely to be employed in areas at urbanization level 1 (OR = 1.17), 3 (OR = 1.37), and 6 (OR = 1.48), which represent highly urbanized areas within the urban, suburban, and rural categories, respectively, than in urbanization level 4. CONCLUSION: Clinics in Taiwan showed nursing shortages and maldistribution, with 72.3% RCN and variations based on urbanization and specialty. These factors may be considered in nursing research conducted in other countries to inform future workforce planning.

Disparity of physician specialties in the management of chronic heart failure: trend analysis in Taiwan, 2000 - 2010.

OBJECTIVE: Chronic heart failure (CHF) is a condition that is daily confronted by clinicians in a variety of medical specialties, where physicians routinely seek optimum pharmacotherapy for their outpatients with CHF. We conducted a population- based study on pharmacotherapy for outpatients with CHF in Taiwan from 2000 to 2010, which focused on drug prescription patterns of different physician specialties. MATERIALS AND METHODS: We retrieved records from the National Health Insurance Research Database of patient ambulatory visits with diagnosed chronic heart failure, when cardiovascular drugs were prescribed. For purposes of this study, anti-chronic heart failure drugs were separated into categories: mortality reducing agents (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, ß-blockers, spironolactone, hydralazine plus nitrates) and symptom-relieving agents (digoxin, diuretics). Thereafter, the trends of prescription patterns related to different physician specialties were analyzed. RESULTS: From 2000 to 2010, the prescription rate of any mortality-reducing agent for CHF outpatients rose from 61.5% to 76.3% while the concomitant rate for digoxin decreased from 47.3% to 45.4%. Compared to internists and family physicians, cardiologists not only prescribed far more mortality-reducing agents from 2000 to 2010 (53.9 - 72.7%, 54.1 - 64.3%, 74.7 - 84.4%, respectively), but also prescribed two or three mortality-reducing drugs. CONCLUSION: There was a significant improvement of optimal pharmacotherapy for chronic heart failure in Taiwan. We observed that cardiologists were more aggressive than non-cardiologists when deciding whether to prescribe mortality-reducing drugs for heart failure management. However, those factors which influence the prescription patterns of internists and family physicians for their patients with CHF still require additional research.

Dosing variability in prescriptions of acetaminophen to children: comparisons between pediatricians, family physicians and otolaryngologists.

BACKGROUND: To estimate the extents of dosing variability in prescriptions of acetaminophen to children among pediatricians, family physicians and otolaryngologists. METHODS: The acetaminophen prescriptions in the systematic sampling datasets from the National Health Insurance Research Database in Taiwan were analyzed. The distribution of dosages was measured and expressed in terms of coefficient of variation (CV). The analyses were stratified by patient's age, prescriber's specialty and preparation form. RESULTS: From 13,868 prescribed items of acetaminophen in 2009, liquids accounted only for 11.1% (n = 1544). More than half (56.9%) of liquids were prescribed by pediatricians. The median dose (83.3 mg, n = 1683) of acetaminophen prescriptions in infants is around half of that in preschool children (166.7 mg, n = 3921), one-third in children (250.0 mg, n = 4926) and one-sixth in adolescents (500.0 mg, n = 3338). In infants, the prescriptions by pediatricians had the highest CV (86.7%), followed by family physicians (82.3%) and otolaryngologists (70.3%). The patterns were similar in preschool children and children, but the difference of CV among specialties narrowed down with the patient's age. CONCLUSIONS: In acetaminophen prescriptions to children, pediatricians had a wider variability of dosages and a higher ratio of liquid preparations than family physicians and otolaryngologists. Further investigations can be undertaken to estimate the accuracy of dosing variability as an indicator of prescribing quality. Besides, child-suitable drug preparations should be promoted to ensure patient safety.

Predictors and impact of microsurgical complications in patients with locally advanced oral squamous cell carcinoma.

Microvascular free flap transfer for post-oncologic reconstructive surgery in oral cancer is considered to be a challenge due to the complexity of the anatomy and function of the region. We sought to identify possible factors associated with microsurgical complications and to assess the impact of these complications in relation to patient survival. Following the inclusion and exclusion protocol, 142 patients with stage III and IV oral squamous cell carcinoma (OSCC) who underwent immediate free flap reconstruction after tumor ablation were included in the study. Clinical and surgical procedural-related factors were retrieved from a database and analyzed retrospectively; survival data were evaluated using the Kaplan-Meier method. Major complications that required re-anastomosis of the flap vessels occurred in 23 patients (16.2%); total necrosis of the flaps, regardless of salvage treatment, occurred in seven cases, with 95.1% of full flap survival. The American Society of Anesthesiologists classification, types of neck dissection, and number of flaps were regarded as strong predictors for surgical complications. Patients with these complications appeared to have a shortened survival (5-year cancer-specific survival of approximately 60%, both in stage III and IV OSCC). However, the impact of surgical complications on survival was significant only in stage III OSCC (P = 0.037). Strategies to minimize surgical complications should be used to ensure better prognoses for these patients.

Factors related to overweight and obese populations maintaining metabolic health.

Background: For people who are overweight or obese, maintaining a metabolically healthy status can decrease the risks of developing cardiovascular diseases and Type 2 diabetes. Despite this, only a limited amount of research has discussed the metabolically healthy overweight and obesity (MHOO) population in Asia and the factors associated with them maintaining their metabolic health. Methods: This study enrolled 195 MHOO participants from communities in northern Taiwan during 2009-2010 (baseline). Of the 195 participants, 89 completed the follow-up assessment after a median follow-up time of nine years. Body type was determined by body mass index (BMI, kg/m2). We defined overweight as a BMI ≥ 24 kg/m2 and <27 kg/m2 and defined obese as a BMI ≥ 27 kg/m2. Metabolic health was defined as the absence of cardiometabolic diseases and the presence of ≤1 of the cardiometabolic risk factors, namely hypertension, hyperglycemia, hypertriglyceridemia, and low serum high-density lipoprotein cholesterol. Metabolic health, BMI, and other covariates were evaluated at both baseline and follow-up. Generalized estimating equations (GEE) models were used to analyze the factors associated with maintenance of metabolic health during the follow-up period. Results: At baseline, the mean age of the study participants was 47.4 (SD 5.3) years and 46 (51.7%) of the participants were women. There were 51 (57.3%) individuals who maintained their metabolic health status at the time of the nine-year follow-up. The detrimental factors pertaining to metabolic health included older age, longer duration until follow-up, BMI ≥ 27 kg/m2, and increase in waist circumference. No significant relationships were observed between sociodemographic factors and lifestyle factors, such as sex, level of education, cigarette smoking, alcohol consumption, and physical activity, and sustained metabolic health among MHOO individuals. Conclusions: To maintain metabolic health and prevent negative changes in health status, control of bodyweight and waist circumference should remain a priority for MHOO individuals even when there are no metabolic disorders present.

Magnolol reduces myocardial injury induced by renal ischemia and reperfusion.

BACKGROUND: Magnolol is a component of the bark of Magnolia officinalis, which is a traditional herbal remedy used in China. In this study, we investigated whether magnolol can reduce myocardial injury induced by renal ischemia and reperfusion (I/R). METHODS: Renal I/R was elicited by a 60-minute occlusion of the bilateral renal arteries and a 24-hour reperfusion in Sprague-Dawley rats. Magnolol was administered intravenously 10 minutes before renal I/R to evaluate its effects on myocardial injury induced by renal I/R. RESULTS: Renal I/R significantly increased the serum levels of creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and cardiac troponin I and caused myocardial damage. The terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling-positive nuclei and caspase-3 activation was significantly increased in the myocardium, indicating increase of apoptosis. Echocardiography revealed left ventricular dysfunction, as evidenced by reduction of left ventricular ejection fraction and left ventricular fractional shortening. Furthermore, serum levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1ß, and IL-6 were significantly elevated, while the IL-10 level was suppressed. However, intravenously, pretreatment with magnolol at doses of 0.003 and 0.006 mg/kg 10 minutes before renal I/R significantly prevented the increases of CPK, LDH, and cardiac troponin I levels, as well as the histological damage and the apoptosis in the myocardium. Echocardiography showed significant improvement of left ventricular function. Furthermore, the increases in TNF-α, IL-1ß, and IL-6 and the decrease in IL-10 were significantly limited, while Bcl-2 was increased and Bax was decreased in the myocardium. Phosphorylation of Akt and extracellular signal-regulated kinases 1 and 2 was increased, while phosphorylation of p38 and c-Jun N-terminal kinase was reduced. CONCLUSION: Magnolol reduces myocardial injury induced by renal I/R. The underlying mechanisms for this effect might be related to modulation of the production of pro- and anti-inflammatory cytokines and the limiting of apoptosis.

Risk Factors and Incidence Rates of Self-Reported Short-Term Adverse Events of COVID-19 Vaccine Booster Dose.

With the spread of the new SARS-CoV-2 variants, many countries have begun COVID-19 vaccine booster programs with the mix-and-match strategy. However, research on the adverse events (AE) of booster doses is still scarce. The aim of our study was to analyze the reported incidence rate (IR), and factors associated with AE, including short-term serious adverse events (SAE) and short-term non-serious adverse events (NSAE), among different vaccine products through the hospital-based Vaccine Adverse Event Reporting System (VAERS). A total of 7432 records were collected during the three-month study period. While more than half of the responses (52.2%) reported the presence of AE after receiving a booster dose, only a few AE were considered SAE (2.4%). AE were significantly higher among women and people of younger age, and the brand of vaccines is the strongest factor associated with post-booster dose AE. The incidence of AE in mRNA1273 is higher than in BNT162b2 and MVC-COV1901 (IRR mRNA1273 vs. BNT162b2: 1.22, 95% CI: 1.11-1.34; BNT162b2 vs. MVC-COV1901: 2.77, 95% CI: 2.27-3.39). The IR of different groups were calculated to support the decision making of the booster vaccine. Although AE were not uncommon for booster vaccines, almost all AE were not serious and predictable using estimated IR. This result can be used to optimize booster vaccine decision making.

Haptoglobin phenotypes and plasma haptoglobin levels in patients with abdominal aortic aneurysm.

OBJECTIVE: Inflammation is associated with the disruption of the aortic media and appears to play a fundamental role in the progression and development of abdominal aortic aneurysm (AAA). Haptoglobin (Hp) is a genetically determined acute phase protein, the synthesis of which is increased during inflammation. This study was designed to investigate both phenotype and plasma levels of Hp in patients with AAA. METHODS: Patients with documented AAA who were admitted for elective open repair operation or endograft stent implantation, and non-AAA subjects admitted for coronary arteriography, but found to have normal or insignificant coronary artery disease, were included in the study. Plasma Hp levels were determined using a standard specific enzyme-linked immunosorbent assay, while Hp phenotype was determined by native polyacrylamide gel electrophoresis. Total cholesterol, high density lipoprotein, low density lipoprotein, and triglyceride levels were analyzed enzymatically, and C-reactive protein was analyzed by immunochemistry. RESULTS: Forty-five patients with AAA and 49 non-AAA subjects were included. The Hp 2-2 phenotype was more predominant in AAA patients compared with non-AAA subjects, but this difference was not significant (67% vs 47%; P = .141), while plasma Hp concentrations were significantly higher in AAA patients (237 ± 144 vs 163 ± 86 ng/mL; P = .024). Further analysis revealed that plasma Hp concentrations were significantly higher in AAA patients with the 2-2 phenotype compared with corresponding non-AAA subjects (238 ± 144 vs 163 ± 86 ng/mL;P = .024). CONCLUSIONS: Our findings suggest that plasma Hp concentrations are elevated in patients with AAA, particularly those with the Hp 2-2 phenotype.

Association of apolipoprotein J polymorphism 1598delT with coronary artery disease and lipoprotein levels.

OBJECTIVES: To investigate a polymorphism of the apolipoprotein J (APOJ) gene in relation to coronary artery disease (CAD) and lipid variables in a Chinese male population of genetically unrelated individuals. METHODS: In this study, we recruited 126 control male subjects and 237 CAD male patients. CAD was defined as a fixed stenotic lesion with luminal narrowing ≥50% in at least one of the major or minor coronary arteries. In cases with documented myocardial infarction, only those rated as fully recovered for more than 3 months were enrolled. Patients with acute or chronic infectious diseases and those with malignancies were excluded. All subjects with a fasting serum triglyceride level higher than 300 mg/dl were likewise excluded. RESULTS: We identified a single nucleotide polymorphism, 1598delT, and showed its association with CAD. Subjects with the I/I genotype showed a significantly higher CAD risk compared to those with the D/D genotype (OR 2.34, 95% CI 1.11-4.94, p = 0.026). Patients with the I/I genotype also had abnormal levels of high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol associated with CAD. CONCLUSIONS: Our data indicated that the APOJ single nucleotide polymorphism (1598delT) is associated with risk factors for CAD in a Chinese population.

Varied impacts on outpatient services among departments and divisions in the early phase of the COVID-19 pandemic: Implications for personnel mobilization and preparatory training.

BACKGROUND: Coronavirus disease 2019 (COVID-19) spread all over the world in 2020. In the face of the sudden pandemic, workforce mobilization has been of critical concern to medical institutions. During the pandemic, the public's behaviors of seeking medical assistance have also changed. Using the real-world data of a large medical center in Taiwan, this study aimed to analyze the fluctuations of outpatient visits among various departments and divisions in the early phase of the COVID-19 pandemic and to provide suggestions for staff allocation in similar future events. METHODS: Data of outpatient visits at Taipei Veterans General Hospital were obtained for analysis. The weekly fluctuations of outpatient visits among 36 departments or divisions were computed for 8 weeks from February 3 to March 29, 2020, the early phase of the pandemic. The monthly data of outpatient visits by department and division in March 2020 were also extracted for comparison with those in March 2019. A simple regression equation was used to calculate the weekly trends. RESULTS: Average outpatient visits decreased by 26% in 2 months following the outbreak. Among the 36 departments or divisions, ophthalmology, orthopedics, and cardiology underwent marked declines after the outbreak; the slopes of the simple regression equation were -110.8, -100.7, and -99.2, respectively. By contrast, transfusion medicine, toxicology, transplantation surgery, pediatric surgery, chest surgery, technical aid, and oncology were divisions less influenced. In the year-over-year comparison, infection was the only department or division with positive growth (20.5%), whereas all others exhibited negative growth. CONCLUSION: In the future, we can fulfil the additional personnel needs during a pandemic by redeploying physicians from departments experiencing a reduced workload. Hospitals should also establish preparatory employee training programs to ensure that the reassigned personnel are adequately equipped to serve in their new positions.

Changes in metabolic syndrome affect the health-related quality of life of community-dwelling adults.

Metabolic syndrome (MetS) is associated with cardiovascular diseases, type 2 diabetes, chronic renal diseases, and all-cause mortality. Furthermore, MetS is associated with poor health-related quality of life (HRQOL). However, the impact of dynamic changes in MetS on changes in the HRQOL was not previously explored. This was an eight-year, prospective cohort study in which 906 middle-aged adults from Shipai, Taipei in northern Taiwan were enrolled during 2009-2010 (baseline). Of those sampled, 427 participants completed the follow-up investigation after 8 years. The HRQOL was measured using the Short Form Health Survey (SF-36). Other variables including age, sex, marital status, level of education, smoking, alcohol consumption, baseline body mass index, and changes in physical activity were adjusted. Compared with adults who never experienced MetS, adults with persistent MetS had a negative change in mental HRQOL (ß - 4.20, 95% CI - 7.54 to - 0.86, p = 0.01). The negative changes of persistent MetS on the HRQOL were in the domains of vitality and mental health (ß - 4.42, 95% CI - 8.10 to - 0.73 and ß - 3.47, 95% CI - 6.90 to - 0.04, respectively). Women and overweight adults were vulnerable to the detrimental effects of persistent MetS. For better HRQOL, more resources should be devoted to reversing MetS in public health.

Do Metabolically Healthy People with Obesity Have a Lower Health-Related Quality of Life? A Prospective Cohort Study in Taiwan.

The association between metabolically healthy obesity (MHO) and health-related quality of life (HRQOL) has not been thoroughly evaluated. This study enrolled 906 adult participants aged 35-55 years between 2009 and 2010 in Northern Taiwan; 427 participants were followed up after eight years. Normal weight, overweight, and obesity were evaluated via body mass index. Metabolic health was defined as the absence of cardiometabolic diseases and having ≤1 metabolic risk factor. HRQOL was evaluated using the 36-Item Short Form Health Survey (SF-36), Taiwan version. Generalized linear mixed-effects models were used to analyze the repeated, measured data with adjustment for important covariates. Compared with metabolically healthy normal weight individuals, participants with metabolically unhealthy normal weight and obesity had a significantly poorer physical component summary score (ß (95% CI) = -2.17 (-3.38--0.97) and -2.29 (-3.70--0.87), respectively). There were no significant differences in physical and mental component summary scores among participants with metabolically healthy normal weight, overweight, and obesity. This study showed that metabolically healthy individuals with obesity and normal weight had similar HRQOL in physical and mental component summary scores. Maintaining metabolic health is an ongoing goal for people with obesity.

Pharmacist Workforce at Primary Care Clinics: A Nationwide Survey in Taiwan.

Although dispensing is usually separated from prescribing in healthcare service delivery worldwide, primary care clinics in some countries can hire pharmacists to offer in-house dispensing or point-of-care dispensing for patients' convenience. This study aimed to provide a general overview of pharmacists working at primary care clinics in Taiwan. Special attention was paid to clarifying the relationship by location, scale, and specialty of clinics. The data source was the Government's open database in Taiwan. In our study, a total of 8688 pharmacists were hired in 6020 (52.1%) 11,546 clinics. The result revealed significant differences in the number of pharmacists at different specialty clinics among levels of urbanization. Group practices did not have a higher probability of hiring pharmacists than solo practices. There was a higher prevalence of pharmacists practicing in clinics of non surgery-related specialties than in surgery-related specialties. Although the strict separation policy of dispensing and prescribing has been implemented for 2 decades in Taiwan, most primary care clinics seem to circumvent the regulation by hiring pharmacists to maintain dominant roles in dispensing drugs and retaining the financial benefits from drugs. More in-depth analyses are required to study the impact on pharmacies and the quality of pharmaceutical care.
