Safety of an inactivated SARS-CoV-2 vaccine among healthcare workers in China

Background: Although the inactivated SARS-CoV-2 vaccine (CoronaVac) has undergone preclinical tests and clinical trials evaluating its efficacy and safety, few data have been reported in the post-licensure real-world setting. We aimed to assess the safety of the vaccine among healthcare workers.Methods: A self-administered online survey on monitoring adverse reactions post vaccination was conducted among the staff who worked at and were vaccinated in a tertiary hospital in Taizhou, China, from February 24 to 7 March 2021. A total of 1526 subjects responded to the questionnaire when they received an e-mail or an e-poster on WeChat.Results: The incidences of overall adverse reactions after the first and second injections were 15.6% (238/1526) and 14.6% (204/1397), respectively. The most common adverse reaction was localized pain at the injection site, with an incidence of 9.6% and 10.7% after each dose, accounting for 61.8% and 73.0% of adverse reactions, respectively. Fatigue, muscle pain, and headache were the most common systemic adverse reactions.Conclusions: These findings implied that the inactivated CoronaVac vaccine has an acceptable safety profile among healthcare workers due to the low incidence of self-reported adverse reactions. This may boost public confidence in nationwide mass vaccination campaigns.

Clinical Knowledge Supported Acute Kidney Injury (AKI) Risk Assessment Model for Elderly Patients

From the clinical viewpoint, the statistical approach is still the cornerstone for exploring many diseases. This study was conducted to explore the risk factors related to acute kidney injury (AKI) for elderly patients using the multiple criteria decision-making (MCDM) approach. Ten nephrologists from a teaching hospital in Taipei took part in forming the AKI risk assessment model. The key findings are: (1) Comorbidity and Laboratory Values would influence Comprehensive Geriatric Assessment; (2) Frailty is the highest influential AKI risk factor for elderly patients; and (3) Elderly patients could enhance their daily activities and nutrition to improve frailty and lower AKI risk. Furthermore, we illustrate how to apply MCDM methods to retrieve clinical experience from seasoned doctors, which may serve as a knowledge-based system to support clinical prognoses. In conclusion, this study has shed light on integrating multiple research approaches to assist medical decision-making in clinical practice.

Characterizing spatiotemporal progression and prediction of infarct lesion volumes in experimental acute ischemia using quantitative perfusion and diffusion imaging

PURPOSE

This study was conducted to explore the diagnostic value of arterial spin labeling (ASL) combined with diffusion weighted imaging (DWI) in characterizing the spatiotemporal progression of infarct lesions in a rabbit middle cerebral artery occlusion (MCAO) model and predicting the acute cerebral infarction (ACI) volume.

MATERIALS AND METHODS

Forty-two male rabbits (2.9 ± 0.2 kg body weight) were used in this experimental study. Animals were initially anesthetized by intravenous injection of uratan. There were seven experimental groups with six rabbits in each group. The apparent diffusion coefficient (ADC) and cerebral blood flow (CBF) thresholds were established in the control group (n = 6), which were sacrificed at 12 h, stained for infarct volume, and imaged at each time point.

RESULTS

The normal ADC and CBF were estimated as 0.90 ± 0.03 × 10^-3 mm²/s and 0.68 ± 0.06 mL g^-1 min^-1, respectively. The viability thresholds of ADC and CBF yielding the lesion volumes (LVs) at 3 h, which best approximated the 2,3,5-triphenyltetrazolium chloride (TTC) infarct volumes at 12 h, were 0.52 ± 0.02 × 10^-3 mm²/s (42.2 ± 3% reduction) and 0.33 ± 0.09 mL g^-1 min^-1 (51.0 ± 11% reduction), respectively. The temporal evolution of the ADC- and CBF-defined LVs showed a significant perfusion/diffusion mismatch up to 1 h (p = 0.001).

CONCLUSION

ADC values and ACI volumes were positively correlated, while CBF was negatively correlated, which is supposed to be a reference for predicting ACI volume.

Assessment of mental health among nursing staff at different levels

To assess the mental health of nurses and to find the post responsibility and psychological status of clinical nurses.A total of 447 nursing staff at different levels in a teaching hospital was assessed by nursing post responsibility scale and mental symptom checklist (SCL-90) then compared with each other. The study period was from April 1, 2018 to April 30, 2018.There was a positive correlation between the responsibility of post and interpersonal relationship (r = 0.11, P < .05), depression (r = 0.10, P < .05) and hostility (r = 0.10, P < .05). Post risk was negatively correlated with somatization (r = -0.10, P < .05), job involvement scope and communication ability were negatively correlated (r = -0.11, P < .05). Based on the multiple linear regression, knowledge and skills (β = -0.20, P = .02) and risks of the post (β=0.20, P < .01) both significantly related to SCL-90 total score.In conclusion, knowledge and skills and risks of the post associated with mental health of clinical nurses. The sustainable development of nursing post responsibility requires healthy physiological and mental health.

Effects of protective factors on the depressive status of elderly people in Taiwan

This study was conducted to examine the effect of protective factors on the relationship between crisis episodes and depression in the elderly population in Taiwan.In this study, the Taiwan Longitudinal Study on Aging was used as basis for a cross-sectional secondary data analysis. After eliminating respondents below the age of 65 years and those with missing values, 2426 samples were collected. Predictive variables, such as crisis episodes, personal resources, family ties, social participation, and social support, were investigated, and the dependent variable of "depression status" was measured using the Center for Epidemiologic Studies Depression scale.According to the results of regression analysis, the protective factors of self-assessed health (ß = -0.290, P < .001), instrumental support (ß = -0.153, P < .001), financial satisfaction (ß = -0.126, P < .001), emotional support (ß = -0.101, P < .001), crisis episodes (ß = 0.087, P < .001), support satisfaction (ß = -0.081, P < .001), leisure participation (ß = -0.053, P < .05), family ties (ß = -0.048, P < .05), and community participation (ß = -0.042, P < .05) had a significant effect on depression status. Moreover, leisure participation had a moderating effect on the relationship between crisis episodes and depression (ß = -0.07, P < .01). In addition, according to path analysis results, family ties had a significant negative predictive power on depression (β = -0.225, P < .001), as did social support (β = -0.978, P < .001). The predictive power of crisis episodes on depression through social support was 0.197 (-0.201 × -0.978 = 0.197, P < .001), and it was -0.324 (-0.331 × -0.978 = -0.324, P < .001) through social participation, which indicated that social support plays a mediating role between crisis episodes and depression and between social participation and depression.Strengthening effective protective factors can improve the resilience of elderly people and enable them to cope with dilemmas rapidly and effectively when faced with crisis episodes as well as restore their health status and enjoy a satisfactory life.

Effectiveness of Yoga Interventions in Breast Cancer-Related lymphedema: A systematic review

OBJECTIVES

To synthesize recent empirical evidence on yoga-based interventions for patients with breast cancer-related lymphedema.

METHODS

We searched the PubMed/MEDLINE, Cochrane Central Register of Controlled Trials and EMBASE databases for studies published between October 2007 and September 2018 in any language. Risk of bias and methodological quality were evaluated using the PRISMA statement and checklist and the Cochrane Collaboration tool.

RESULTS

There was significant improvement in lymphedema status, range of shoulder motion and spinal mobility after an 8-week yoga intervention, whereas there was no consistency in quality of life following yoga intervention. Additionally, there was no difference in lymphedema status, extracellular fluid and tissue resistance outcomes in the affected arm following a long-term yoga practice.

CONCLUSION

The current findings could not be clearly demonstrated that yoga programme intervention as an addition to usual care is superior to along usual care, and keep yoga exercise does not provide significant added benefits.

The longitudinal study for the work-related factors to job performance among nurses in emergency department

To explore the relationship between baseline information, personal factors, working characteristics and job performance among nurses in emergency department in northern Taiwan.Two-hundred twenty-two nursing staff were interviewed repeated with structured questionnaires for data collection in 3 time points (From August to September, 2008, from February to March, 2009, and from November to December, 2009). The generalized estimating equation (GEE) is used to test the relationship between the domains of independent variables (baseline information, personal factors, working characteristics) and dependent variables (task performance, contextual performance).The mean age of participants is 30.1 ± 5.1 years. 50.0% are junior college or bachelor degrees. From the GEE model, biological protection (β = 0.17, P value = .002) and safety climate (β = 0.24, P value < .001) are significantly related to task performance. Contextual performance is strongly affected by safety climate (β = 0.15, P value < .001).To improve the job performance among nurses in emergency department, it should consider personal psychological and environmental factors.

The effects of aromatherapy massage on improvement of anxiety among patients receiving palliative care: A systematic review of randomized controlled trials

BACKGROUND

Anxiety in patients receiving palliative care is a noteworthy concern because it may affect their quality of life. Aromatherapy has been widely utilized to improve anxiety among patients receiving palliative care.

OBJECTIVE

To investigate the effectiveness of anxiety improvement in patients receiving palliative care by comparing the intervention group (aromatherapy massage) with the control group (common massage alone).

METHODS

A literature search was performed using PubMed, Cochrane Library, Embase, MEDLINE, and CINAHL for all related studies from inception through November 30, 2018 without restriction on language. A quantitative synthesis of randomized controlled trials (RCTs) was conducted to compare the difference in effectiveness scores between the aromatherapy massage and only common massage groups by employing a random-effect model.

RESULTS

We included three RCTs with a total of 160 participants (81 in the intervention group and 79 in the control group) in our systematic review and conducted a quantitative synthesis. The secondary data from the reviewed trials were then pooled using a random-effect model. Anxiety (mean difference = -2.60 [95% confidence interval: -7.82, 2.63], P = .33) was assessed using anxiety scores from the State-Trait Anxiety Inventory.

CONCLUSION

Compared with common massage alone, aromatherapy massage does not provide significant effectiveness of anxiety improvement among patients receiving palliative care.

Hemodialysis interval and its association with emergency care and mortality: A nationwide population-based cohort study

End-stage renal disease (ESRD) incidence in Taiwan is highest worldwide. This study analyzed the relationship between health resource use and patients on hemodialysis (HD) asking for medical help as well as the outcomes in Taiwan.This was a retrospective cohort study that analyzed the medical data of patients on dialysis, which were collected from the National Health Insurance Database of Taiwan for the period 2000 to 2010. The study sample was screened out, and new patients starting HD from 2001 to 2005 were considered.The daily distribution of patients with ESRD in the Monday, Wednesday, and Friday (MWF) and Tuesday, Thursday, and Saturday (TTS) groups who underwent emergent HD showed remarkable person-time on Monday and Tuesday, respectively. The disease (complication) distribution in the MWF group was higher than that in the TTS group, and the statistics of heart-failure-associated diseases were significantly different. Considering 5-year survival status, the mortality rate of patients with HD was 21.94% (255 of 1162), among which those with a history of cerebrovascular disease and diabetes were 68.63% and 72.16%, respectively.Long interdialytic intervals may induce emergency dialysis. Therefore, the frequency of emergent HD therapy has increased (thrice a week), as predicted in the current HD policy.

Different treatments for acute myocardial infarction patients via outpatient clinics and emergency department

To investigate relevant factors and patients with acute myocardial infarction (AMI) were admitted during between weekdays and weekends period.Retrospective population-based study setting: from the 2005 population-based national health insurance underwriting database of millions of people, random sampling (National Health Insurance Research Database [NHIRD]-Longitudinal Health Insurance Database [LHID] 2005).In 2000 to 2009 data of NHIRD, subjects presented with first episode AMI who had received the thrombolytic therapy (TPA), or percutaneous coronary artery intervention (PTCA) or coronary artery bypass graft (CABG) during between weekdays and weekends period.From 2000 to 2009 among patients with first AMI total of 2007 people, the weekday group 1453 people, the weekend group 554. The total mortality within 1 year showed 33.53%, the first-day mortality occupied 8.07% in 1 year of total mortality, increased mortality after admission 3 months later. Cox regression analysis showed that AMI has presented significant risk of death, there are 4 items: weekends, age, Charlson comorbidity index (CCI), thrombolytic therapy; in the other variables including emergency, hospital level, hospital ownership, and urban-rural gap are not significant differences. Further using hierarchical logistic regression analysis for Stratification of AMI mortality risk, it has significant that showed the hospital level, age, CCI, thrombolytic therapy; but emergency, PTCA and 3 CABG treatment are not significant differences.It was approved by the hierarchical logistic regression analysis after stratified correction that the present study will have a direct impact on weekdays and weekends death in the hospital level. It will also affect the individual level.

The relation between patient education, patient empowerment and patient satisfaction: A cross-sectional-comparison study

PURPOSE

Patient empowerment is a paradigm of clinical practice. The goal of patient empowerment is to lead patients' health and wellbeing. The aim of this study is to evaluate the relation between patient education, patient empowerment and patient satisfaction based on multi-hospital cross-sectional study design in Taiwan.

METHODS

In this cross-sectional survey, 609 inpatients in four teaching hospitals in northern Taiwan from August 2009 to July 2010 were recruited. Data were collected using Chinese version of the Patient Perceptions of Empowerment Scale (PPES), Sufficiency of Patient Education Questionnaire (SPEQ) and Patient Satisfaction Questionnaire (PSQ). The multiple linear regression model was used to assess the independent effects of relevant factors on patient empowerment after controlling for the covariates.

RESULTS

The overall mean empowerment scores was 44.80±5.94. There was a significant difference between the total scores and four dimensions of patient empowerment at different hospitals (t=5.44, p≤0.01). Sufficient patient education (β=0.568, 95%CI: 0.486-0.649) and patient satisfaction (β=0.317, 95%CI: 0.259-0.375) could significantly predict patient empowerment based on the multiple linear regression analysis, with a total variance was 54.4%.

CONCLUSIONS

In conclusion, both sufficient patient education and patient satisfaction were positively related to patient empowerment. Hospitals in Taiwan should try to improve their patients' active involvement toward empowerment.

Risk of Suicidality in People with Psoriasis: A Systematic Review and Meta-Analysis of Cohort Studies

BACKGROUND

Psoriasis has been associated with psychiatric disorders such as depression and anxiety, but its relationship with suicidality (including suicide, suicide attempt, and suicidal ideation) is unclear.

OBJECTIVE

Our objective was to assess the risk of suicide, suicide attempt, suicidal ideation, and suicidality in people with psoriasis.

METHODS

We conducted a systematic review and meta-analysis of cohort studies examining the risk of suicide, suicide attempt, suicidal ideation, and suicidality in people with psoriasis. We searched the Cochrane Library, PubMed, and EMBASE from inception to 24 March 2017. Two authors independently selected studies, assessed the quality of included studies, and extracted data. Any disagreement was resolved by discussion with a third author.

RESULTS

Five population-based cohort studies were included and considered to be of high quality. We found no increase in the risk of suicide (risk ratio [RR] 1.13; 95% confidence interval [CI] 0.87-1.46), suicide attempt (RR 1.25; 95% CI 0.89-1.75), or suicidality (RR 1.26; 95% CI 0.97-1.64) among people with psoriasis. In the stratified analysis, we also found no increase in suicide, suicide attempt, and suicidality among people with either severe or mild psoriasis.

CONCLUSIONS

The available limited, very low-quality evidence does not support an association between psoriasis and suicidal thought and behavior. Further studies that provide data for different age and sex groups are needed to clarify whether a subgroup of patients with psoriasis has an elevated risk of suicidality.

Periodontal Pocket Depth, Hyperglycemia, and Progression of Chronic Kidney Disease: A Population-Based Longitudinal Study

BACKGROUND

No large epidemiological study has been conducted to investigate the interaction and joint effects of periodontal pocket depth and hyperglycemia on progression of chronic kidney disease in patients with periodontal diseases.

METHODS

Periodontal pocket depth was utilized for the grading severity of periodontal disease in 2831 patients from January 2002 to June 2013. Progression of chronic kidney disease was defined as progression of color intensity in glomerular filtration rate and albuminuria grid of updated Kidney Disease-Improving Global Outcomes guidelines. Multivariable-adjusted hazard ratios (aHR) in various models were presented across different levels of periodontal pocket depth and hemoglobin A1c (HbA1c) in forest plots and 3-dimensional histograms.

RESULTS

During 7621 person-years of follow-up, periodontal pocket depth and HbA1C levels were robustly associated with incremental risks for progression of chronic kidney disease (aHR 3.1; 95% confidence interval [CI], 2.0-4.6 for periodontal pocket depth >4.5 mm, and 2.5; 95% CI, 1.1-5.4 for HbA1C >6.5%, respectively). The interaction between periodontal pocket depth and HbA1C on progression of chronic kidney disease was strong (P <.01). Patients with higher periodontal pocket depth (>4.5 mm) and higher HbA1C (>6.5%) had the greatest risk (aHR 4.2; 95% CI, 1.7-6.8) compared with the lowest aHR group (periodontal pocket depth ≤3.8 mm and HbA1C ≤6%).

CONCLUSION

Our study identified combined periodontal pocket depth and HbA1C as a valuable predictor of progression of chronic kidney disease in patients with periodontal diseases. While considering the interaction between periodontal diseases and hyperglycemia, periodontal survey and optimizing glycemic control are warranted to minimize the risk of worsening renal function.

Epidemiology, management, and economic evaluation of screening of gallstone disease among type 2 diabetics: A systematic review

The knowledge of gallstone disease (GSD) is crucial to manage this condition when organizing screening and preventive strategies and identifying the appropriated clinical therapies. Although cholecystectomy still be the gold standard treatment for patients with symptomatic GSD, expectant management could be viewed as a valid therapeutic method for this disorder. If early treatment of GSD decreases the morbidity or avoids further cholecystectomy, it may save clinical care costs in later disease periods sufficiently to offset the screening and early treatment costs. In addition, whether routine screening for GSD is worthwhile depends on whether patients are willing to pay the ultrasonography screening cost that would reduce the risk of cholecystectomy. In this review we discuss the epidemiology, management, and economic evaluation of screening of GSD among type 2 diabetics.

Economic and medical benefits of ultrasound screenings for gallstone disease

AIM: To investigate whether screening for gallstone disease was economically feasible and clinically effective.

METHODS: This clinical study was initially conducted in 2002 in Taipei, Taiwan. The study cohort total included 2386 healthy adults who were voluntarily admitted to a regional teaching hospital for a physical check-up. Annual follow-up screening with ultrasound sonography for gallstone disease continued until December 31, 2007. A decision analysis using the Markov Decision Model was constructed to compare different screening regimes for gallstone disease. The economic evaluation included estimates of both the cost-effectiveness and cost-utility of screening for gallstone disease.

RESULTS: Direct costs included the cost of screening, regular clinical fees, laparoscopic cholecystectomy, and hospitalization. Indirect costs represent the loss of productivity attributable to the patient’s disease state, and were estimated using the gross domestic product for 2011 in Taiwan. Longer time intervals in screening for gallstone disease were associated with the reduced efficacy and utility of screening and with increased cost. The cost per life-year gained (average cost-effectiveness ratio) for annual screening, biennial screening, 3-year screening, 4-year screening, 5-year screening, and no-screening was new Taiwan dollars (NTD) 39076, NTD 58059, NTD 72168, NTD 104488, NTD 126941, and NTD 197473, respectively (P < 0.05). The cost per quality-adjusted life-year gained by annual screening was NTD 40725; biennial screening, NTD 64868; 3-year screening, NTD 84532; 4-year screening, NTD 110962; 5-year screening, NTD 142053; and for the control group, NTD 202979 (P < 0.05). The threshold values indicated that the ultrasound sonography screening programs were highly sensitive to screening costs in a plausible range.

CONCLUSION: Routine screening regime for gallstone disease is both medically and economically valuable. Annual screening for gallstone disease should be recommended.

Clinical predictors associated with full remission versus episode of major depressive disorder outpatients: the experience at a teaching hospital in Taiwan

BACKGROUND

When depressed patients are in remission, the clinical characteristics indicate that they are able to participate in social activities more regularly, and their impairment in daily functioning is improved. The present study examines the clinical characteristics associated with one- and two month clinical response in outpatients with Major Depressive Disorder (MDD) in Taiwan.

METHODS

A total of 160 outpatients were initially recruited from the medical centre in Taiwan. Of these participants, 151 MDD patients completed the baseline-assessment interview, 111 were interviewed and assessed again 4 weeks later, and 78 completed the final interview and assessment 8 weeks later. In the present study, asymptomatic was defined as scoring ≤ 7 on the Hamilton Depression Rating Scale (HAM-D); partially symptomatic was defined as scoring 8-14; fully symptomatic was defined as scoring ≥15. Finally, asymptomatic, partially symptomatic, and fully symptomatic were defined in patients with MDD respectively as in full remission, in persistent depressive symptom, and in episode.

RESULTS

Of the remaining 78 patients, a total of 21 (26.9%) were in full remission, 35 (44.9%) were in persistent depressive symptom, and 22 (28.2%) were in episode. Patients in full remission were older (p = 0.03), exhibited greater psychosocial functioning, (p < 0.001), held more-positive beliefs regarding antidepressant medication (p = 0.03), had higher self-efficacy (p = 0.001), and scored lower for neuroticism (p = 0.003), as compared to patients in episode. Younger patients were more prevalent in persistent depression. Repeated-measures ANOVA revealed that differences in four factors (psychosocial functioning, beliefs regarding antidepressant medication, self-efficacy in managing and preventing depression, and neuroticism) were significantly different between full remission and episode. Episode was significantly associated with psychosocial-functioning impairment (OR = 1.12, 95% CI: 1.00-1.26) and poorer self-efficacy (OR = 0.91, 95% CI: 0.82-1.00).

CONCLUSIONS

Our findings identify significant factors of full remission, persistent depressive symptom, and episode. We highlight the importance of enhancing patients' psychosocial functioning and self-efficacy until achieving full remission. Suggestions are provided for clinical health-care management services in Taiwan.

Relationship between obesity, metabolic syndrome, and nonalcoholic fatty liver disease in the elderly agricultural and fishing population of Taiwan

Background

The purpose of this study was to explore the relationship between obesity, the metabolic syndrome, and nonalcoholic fatty liver disease (NAFLD) in the elderly agricultural and fishing population of Taipei, Taiwan.

Methods

The study participants comprised 6,511 (3,971 male and 2,540 female) healthy elderly subjects voluntarily attending a teaching hospital for a physical check-up in 2010. Blood samples and real-time ultrasound-proven fatty liver sonography results were collected.

Results

The prevalence of NAFLD in this elderly population was 27.2%, including mild NAFLD (16.0%), moderate NAFLD (10.3%), and severe NAFLD (0.9%). The prevalence of moderate or severe NAFLD for metabolic syndrome proved to be substantially greater (P<0.0001, χ² test) for one or two metabolic factors. Using multinomial logistic regression analysis, age, sex, metabolic syndrome, and higher body mass index had a statistically significant association with mild NAFLD. Age, sex, metabolic syndrome, higher body mass index, and higher alanine aminotransferase were significantly related to moderate NAFLD. In addition, higher body mass index, higher uric acid, and higher alanine aminotransferase levels were significantly related to severe NAFLD. The sensitivity and specificity of body mass index and waist circumference as markers of NAFLD were estimated to be 81% and 84%, respectively, and 77% and 69%, respectively.

Conclusion

The prevalence of mild or moderate NAFLD was related to obesity and metabolic syndrome. Higher body mass index was also related to severe NAFLD but not to metabolic syndrome. Targeting this population for control of obesity and improved metabolic function is important.

Prenatal ultrasonography and Doppler sonography for the clinical investigation of isolated ventricular septal defects in a late second-trimester population

Background

The purpose of this study was to evaluate the efficacy of prenatal ultrasonography and Doppler sonography in detecting isolated ventricular septal defects (VSDs) in a late-second-trimester population.

Methods

Fetal echocardiography, Doppler ultrasound, and biometry were used to evaluate 2,661 singleton fetuses (1,381 male fetuses and 1,280 female fetuses) between 1 August 2006 and 31 May 2010. The efficacy of each fetal biometry, Doppler ultrasound, and nasal bone length (NBL) measurement was evaluated in all of the fetuses. A standard fetal echocardiographic evaluation, including two-dimensional gray-scale imaging and color and Doppler color flow mapping, was performed on all fetuses.

Results

We detected isolated VSDs in 124 of the 2,661 singleton fetuses between 19 and 24 weeks of gestation. The prevalence of isolated VSDs in the study population was 4.66%. A multiple logistic regression analysis indicated that short fetal NBL (odds ratio = 0.691, 95% confidence interval: 0.551 to 0.868) and the pulsatility index (PI) of the umbilical artery (odds ratio = 8.095, 95% confidence interval: 4.309 to 15.207) and of the middle cerebral artery (odds ratio = 0.254, 95% confidence interval: 0.120 to 0.538) are significantly associated with isolated VSDs.

Conclusion

Late-second-trimester fetal NBL, umbilical artery PI, and middle cerebral artery PI are useful parameters for detecting isolated VSDs, and can be used to estimate the a priori risk of VSDs in women at high risk and at low risk of isolated VSDs.

Clinical correlation of nonalcoholic fatty liver disease in a Chinese taxi drivers population in Taiwan: Experience at a teaching hospital

Background

To explore any gender-related differences in the prevalence of conditions-associated with non-alcoholic fatty liver disease (NAFLD) among Taiwanese taxi drivers in Taipei, Taiwan.

Methods

We studied 1635 healthy taxi drivers (1541 males and 94 females) who volunteered for physical check-ups in 2006. Blood samples and ultrasound fatty liver sonography results were collected.

Results

The prevalence of NAFLD was 66.4% and revealed no statistically significant decrease with increasing age (p = 0.58). Males exhibited a greater prevalence of NAFLD than did females (67.5% vs 47.9%, p < 0.0001). Gender-related differences for associated factors were found. For males, hypertension, hyperuricemia, higher AST, higher ALT, hypertriglyceridemia, and higher fasting plasma glucose were significantly related to NAFLD. These conditions were not sigfinicantly related to NAFLD in females.

Conclusion

Several gender-related differences were noted for NAFLD among Taiwanese taxi drivers.

Microaneurysm number and distribution in the macula of Chinese type 2 diabetics with early diabetic retinopathy: a population-based study in Kinmen, Taiwan

To explore the number and distribution of microaneurysms (MA) in the macula of type 2 diabetics in Kinmen, Taiwan and associated risks for early diabetic retinopathy (DR). A baseline mass screening extracts 971 type 2 diabetics between 1991 and 1993 and follow-up eye screening at 1999 was then done. Number of MA was counted and associated systemic factors collected from a centered 45 degrees color fundus photograph of dilated eyes of type 2 diabetics (Topcon-NW5). Thirty-three (6.2%, n = 527) had MA retinopathy. Those with one eye involved (n = 26) had two mean MA; those with bilateral involvement (n = 7) had four mean per eye. Most MA were located temporally (mean MA = 0.79), then superiorly (mean = 0.58), inferiorly (mean = 0.46) and nasal (mean = 0.28). MA occurred at the 6,000-microm outermost ring (mean = 1.51), then the 3,000-microm ring (mean = 0.35), the 1,500-microm ring (mean = 0.26) and center 500 microm circle (mean = 0.01). After adjusting for confounding factors, early DR with MA was associated with longer duration of type 2 diabetes [odds ratios (OR) = 1.10, 95% confidence interval (CI) 1.00-1.21], higher glycosylated hemoglobin (OR = 1.36, 95%CI 1.11-1.66) and wider waist circumference (OR = 1.04, 95%CI 1.01-1.07). Our photograph grading system suggests that MA number and distribution at the macula may reflect severity of early DR and is a valid tool for predicting the progression of DR. Identifying those factors associated with MA only DR is important in developing prevention strategies for this early microvascular complication of type 2 diabetes.
