RESUMO
OBJECTIVE: To measure the effects of faecal immunochemical test (FIT) for colorectal cancer (CRC) screening on overall and site-specific long-term effectiveness of population-based organised service screening. DESIGN: A prospective cohort study of Taiwanese nationwide biennial FIT screening was performed. A total of 5 417 699 eligible subjects were invited to attend screening from 2004 through 2009 and were followed up until 2014. We estimated the adjusted relative rates (aRRs) on the effectiveness of reducing advanced-stage CRC (stage II+) and CRC death by Bayesian Poisson regression models with the full adjustment for a cascade of self-selection factors (including the screening rate and the colonoscopy rate) and the completeness of colonoscopy together with demographic features. RESULTS: FIT screening (exposed vs unexposed) reduced the incidence of advanced-stage CRC (48.4 vs 75.7 per 100 000) and mortality (20.3 vs 41.3 per 100 000). Statistically significant reductions of both incidence of advanced-stage CRCs (aRR=0.66, 95% CI 0.63 to 0.70) and deaths from CRC (aRR=0.60, 95% CI 0.57 to 0.64) were noted. FIT screening was more effective in reducing distal advanced-stage CRCs (aRR=0.61, 95% CI 0.58 to 0.64) and CRC mortality (aRR=0.56, 95% CI 0.53 to 0.69) than proximal advanced CRCs (aRR=0.84, 95% CI 0.77 to 0.92) and CRC mortality (aRR=0.72, 95% CI 0.66 to 0.80). CONCLUSION: A large-scale population-based biennial FIT screening demonstrates 34% significant reduction of advanced-stage CRCs and 40% reduction of death from CRC with larger long-term effectiveness in the distal colon than the proximal colon. Our findings provide a strong and consistent evidence-based policy for supporting a sustainable population-based FIT organised service screening worldwide. The disparity of site-specific long-term effectiveness also provides an insight into the remedy for lower effectiveness of FIT screening in the proximal colon.

OBJECTIVE: To explore whether status epilepticus affected cardiac mortality. METHODS: We used the 2008-2017 multicause mortality data of the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiological Research. The status epilepticus group included patients whose death certificates mentioned status epilepticus as contributing to death. The non-status epilepticus group included patients whose death certificates mentioned epilepsy, other and unspecified convulsions, febrile convulsions, or post-traumatic seizures, as contributing to death. The outcomes for evaluation were death certificates that indicated that myocardial infarction, arrhythmia, heart failure, or cardiac arrest (CA) was the immediate cause of death. The numbers of deaths and population sizes by categorical demographics were recorded and subjected to multiple logistic regression analysis. RESULTS: Among the 14,487 death certificates in status epilepticus group; 3080 patients (21.3%) died of CA. When clinical records were compared to autopsy data, females were at a lower risk of myocardial infarction (odds ratio [OR]: 0.55, 95% confidence interval [CI]: 0.51-0.61). Patients aged 45-65â¯years and older than 65â¯years were at a higher risk of developing all four cardiac complications. Status epilepticus was associated with higher risks of arrhythmia (OR: 1.55, 95% CI: 1.11-2.15) and CA (OR: 4.34, 95% CI: 3.49-5.39) but a reduced risk of myocardial infarction (OR: 0.42, 95% CI: 0.30-0.57) as the cause of immediate death. CONCLUSION: The frequency of CA in patients with status epilepticus increased between 2008 and 2017. Male and elderly patients were at a higher risk of cardiogenic mortality.

AIMS: To evaluate polypharmacy-related problems in the elderly people who live in rural through a proactive pharmaceutical care project under a novel remote medical service infrastructure (the Houston-Apollo polypharmacy project). METHODS: It is a prospectively cross-sectional study. The elderly aged 65 years old lived in communities executed the congregate meal service and joined the Houston-Apollo project were included. During March and July on 2020, the pharmaceutical care team of Houston-Apollo polypharmacy project interviewed old people and collected their medications by remote video. Polypharmacy situation and drug-related problems, including potentially inappropriate medications (PIMs), anticholinergic burden (ACB) and risk of sarcopaenia, were evaluated by clinical pharmacists. In addition, we analysed the categories of the prescription types between polypharmacy and non-polypharmacy users, polypharmacy users with and without PIMs or ACB. A patient-specific integrated pharmacist's note for medication education and a dear doctor letter (as needed) were generated and delivered within 2-weeks postinterviewed. Age- and sex-adjusted logistic regression model was used to evaluate the association between polypharmacy and these potential medication problems. RESULTS: There were 87 older people (mean age = 75.9) and 536 long-term medications were collected. Among them, 52% were defined as polypharmacy users. Polypharmacy was significantly associated with higher risk of PIMs and ACB. The adjusted odd ratio was 5.31 (95% CI: 2.02-13.9) and 10.1 (95% CI: 3.4-29.7), respectively. Among polypharmacy users, there were nearly double the prescriptions for the nervous system and musculoskeletal system among patients with PIMs compared with those without PIMs. Besides, polypharmacy users with ACB showed higher rate of prescriptions for the nervous system and the alimentary tract and metabolism system compared with those without ACB. CONCLUSION: Polypharmacy was significantly associated with negative impact of medication safety among the elderly people in rural area. A persistent remote pharmaceutical care intervention was crucial for improving this problem.

BACKGROUND: As COVID-19 has become a pandemic emerging infectious disease it is important to examine whether there was a spatiotemporal clustering phenomenon in the globe during the rapid spread after the first outbreak reported from southern China. MATERIALS AND METHODS: The open data on the number of COVID-19 cases reported at daily basis form the globe were used to assess the evolution of outbreaks with international air link on the same latitude and also including Taiwan. The dynamic Susceptible-Infected-Recovered model was used to evaluate continental transmission from December 2019 to March 2020 before the declaration of COVID-19 pandemic with basic reproductive number and effective reproductive number before and after containment measurements. RESULTS: For the initial COVID-19 outbreak in China, the estimated reproductive number was reduced from 2.84 during the overwhelming outbreaks in early January to 0.43 after the strict lockdown policy. It is very surprising to find there were three countries (including South Korea, Iran, and Italy) and the Washington state of the USA on the 38° North Latitude involved with large-scale community-acquired outbreaks since the first imported COVID-19 cases from China. The propagation of continental transmission was augmented from hotspot to hotspot with higher reproductive number immediately before the declaration of pandemic. By contrast, there was not any large community-acquired outbreak in Taiwan. CONCLUSION: The propagated spatiotemporal transmission from China to other hotspots may explain the emerging pandemic that can only be exempted by timely border control and preparedness of containment measurements according to Taiwan experience.

BACKGROUND: Vaccine is supposed to be the most effective means to prevent COVID-19 as it may not only save lives but also reduce productivity loss due to resuming pre-pandemic activities. Providing the results of economic evaluation for mass vaccination is of paramount importance for all stakeholders worldwide. METHODS: We developed a Markov decision tree for the economic evaluation of mass vaccination against COVID-19. The effectiveness of reducing outcomes after the administration of three COVID-19 vaccines (BNT162b2 (Pfizer-BioNTech), mRNA-1273 (Moderna), and AZD1222 (Oxford-AstraZeneca)) were modelled with empirical parameters obtained from literatures. The direct cost of vaccine and COVID-19 related medical cost, the indirect cost of productivity loss due to vaccine jabs and hospitalization, and the productivity loss were accumulated given different vaccination scenarios. We reported the incremental cost-utility ratio and benefit/cost (B/C) ratio of three vaccines compared to no vaccination with a probabilistic approach. RESULTS: Moderna and Pfizer vaccines won the greatest effectiveness among the three vaccines under consideration. After taking both direct and indirect costs into account, all of the three vaccines dominated no vaccination strategy. The results of B/C ratio show that one dollar invested in vaccine would have USD $13, USD $23, and USD $28 in return for Moderna, Pfizer, and AstraZeneca, respectively when health and education loss are considered. The corresponding figures taking value of the statistical life into account were USD $176, USD $300, and USD $443. CONCLUSION: Mass vaccination against COVID-19 with three current available vaccines is cost-saving for gaining more lives and less cost incurred.

Despite the continuous progression in dialysis medicine, mortality and the burden of cardiovascular disease (CVD) among hemodialysis patients are still substantial. Substantial evidence suggests that proinflammatory (CD16+) monocytes contribute to the development of atherosclerosis. A cohort of 136 stable hemodialysis patients (follow-up: 6.25 year) was assessed to investigate the association between the proportion of CD16+ monocytes for all-cause and CVD mortalities. The CD16+ monocytes were associated with both mortalities after adjusting for a preexisting CVD history. Compared to the reference group (CD16+ monocytes within [15.6-18.6], the first and second quartile), patients with CD16+ monocytes above the highest quartile level (>21.5) had an adjusted hazard ratio (HR) of 30.85 (95% confidence interval [CI]: 7.12-133.8) for CVD mortality and 5.28 (2.07-13.49) for all-cause mortality, and those with CD16+ monocytes below the lowest quartile ≤15.6), had significantly elevated death risks after 3.5-year follow-up (HR [95% CI]: 10.9 [2.42-48.96] and 4.38 [1.45-13.24] for CV and all-cause mortalities, respectively). The hemodialysis patients with CD16+ monocyte level in a low but mostly covering normal range also portended a poor prognosis. The findings shed some light for nephrologists on future prospects of early recognizing immune dysfunction and improving early intervention outcomes.

OBJECTIVE: Obesity is becoming increasingly common in hemodialysis (HD) patients and is associated with inflammation and increased mortality. The primary aim of the present study was to evaluate the accuracy and variability of the bioimpedance device in measuring body fat in Taiwanese dialysis patients. DESIGN: Cross-sectional study. SUBJECTS: One hundred twenty-two adult patients receiving HD in a single hospital in Taiwan. SETTING: We compared the results of fat mass (FM) measured by dual-energy x-ray absorptiometry (DEXA) and bioelectrical impedance spectroscopy device (Body composition monitor, BCM). MAIN OUTCOME MEASUREMENT: FM measured by BCM was calculated by subtracting fat-free mass (FFM) from body mass assuming fractional hydration of FFM of 0.73 or the proprietary prediction equations from the BCM model. RESULTS: Assessment of whole-body composition showed that percentage FM measured using the 2 techniques was highly correlated when using the BCM model or estimating from total body water using constant (0.73) hydration (r = 0.87, P < .001). There was no evident difference in measurement between patients gender. The Bland-Altman plot also showed good agreement of percentage of FM (t = 3.82; P < .001). In female patients, it was found that BCM significantly underestimated mean FM as compared to DEXA. However, the mean differences of the estimates between the methods were small (0.35 ± 3.00 kg) and with Bland-Altman plot the limits of agreements were -5.5 to 6.2 kg (P = .40) for FM in female patients. CONCLUSIONS: Using DEXA as the reference test, BCM is a valid tool for the assessment of total body fat in HD patients. Hence, it may provide a more accessible tool for early detection of changes in body composition in these high-risk patients.

CONTEXT: Mitochondrial DNA (mtDNA) copy number correlates with tumor pathology in some cancers. OBJECTIVE: To investigate mtDNA copy number in head and neck cancer (HNC). MATERIALS AND METHODS: mtDNA copy number was determined and compared between HNC patients and malignancy-free controls. RESULTS: The mtDNA copy number was significantly higher in HNC patients, increased with cancer progression and correlated negatively with patient survival. DISCUSSION: mtDNA copy number appears to be associated with HNC stage and survival, but confirmation requires similar studies in larger cohorts. CONCLUSION: Studies to establish the nature of the relationship between mtDNA copy number and HNC are warranted.

Background/purpose: The postgraduate year dentist training program (PGYD) officially implemented in 2010. This study aimed to assess PGYD trainees' subjective satisfaction perception and objective competence performance according to different training institutions (either dental clinics or hospitals). Materials and methods: A nationwide cross-sectional survey was conducted in 2018. Subjective satisfaction questionnaires from 222 PGYD trainees and 166 PGYD trainees' scores of objective structured clinical examinations (OSCEs) were collected for analysis. The t-test and logistic regression were used to compare differences between two groups. Results: In subjective satisfaction, PGYD trainees in hospitals revealed less positive perceptions on teachers (odds ratios [ORs] range: 0.33-0.7) and on training plans and auxiliary facilities (ORs range: 0.23-0.69), but they had more opportunities to attend and present at professional meetings than those in clinics. In PGYD trainees' opinion, the optimal training period allocation was 25% in hospitals and 75% in clinics. Overall, trainees in hospitals had better OSCE scores than those in clinics (OR [95% confidence interval, CI]: 3.12 [1.68-5.79]), except for the item of "the relation between physical condition and dental treatment outcome" (0.3 [0.1-0.97]). Conclusion: PGYD trainees in dental clinics have more positive perceptions on teachers and on training plans and auxiliary facilities, but PGYD trainees in hospitals have better OSCE scores. PGYD trainees prefer to be trained in clinics for a better connection with future careers, while hospitals can offer better training for PGYD trainees to become independent dentists because they have better training environment and more educational resources.
RESUMO
Background: Although early dementia detection is crucial to optimize the treatment outcomes and the management of associated symptoms, the published literature is scarce regarding the effectiveness of active screening protocols in enhancing dementia awareness and increasing the rate of early detection. The present study compared the detection ratio of an active community-based survey for dementia detection with the detection ratio of passive screening during routine clinical practice. Data for passive screening were obtained from the National Health Insurance (NHI) system, which was prospectively collected during the period from 2000 to 2003. Design: A population-based cohort study with historical control. Setting: Taiwan. Participants: A total of 183 participants aged 65 years or older were involved in a community-based survey. Data from 1,921,308 subjects aged 65 years or older were retrieved from the NHI system. Measurements: An adjusted detection ratio, defined as a ratio of dementia prevalence to incidence was used. Results: The results showed that the dementia prevalence during the 2000-2003 period was 2.91% in the elderly population, compared with a prevalence of 6.59% when the active survey was conducted. The incidence of dementia in the active survey cohort was 1.83%. Overall, the dementia detection ratio was higher using active surveys [4.23, 95% confidence interval (CI): 2.68-6.69] than using passive detection (1.45, 95% CI: 1.43-1.47) for those aged 65-79 years. Similar findings were observed for those aged 80 years and older. Conclusion: The implementation of an active community-based survey led to a 3-fold increase in the detection rate of early dementia detection compared to passive screening during routine practice.

OBJECTIVES: Whether and how the COVID-19 pandemic affected utilization of routine medical care in areas with low infection risk, such as Taiwan, has not been widely addressed. We aimed to evaluate the impact of the COVID-19 pandemic on access to medical care. STUDY DESIGN: Before and after exposure (COVID-19 pandemic) design with a historical control group for comparison of clinical visits based on a retrospective cohort of 6722 customary patients of a community hospital in Zhunan, Taiwan. METHODS: Repeated measurements of medical utilization in 4-month periods (January to April) of 2019 and 2020 in light of the emerging COVID-19 pandemic were collected. Access to medical care was defined as the mean frequencies of clinical visits. The impacts of the COVID-19 pandemic on access in the overall and specific groups were quantified with a multivariable Poisson regression model. RESULTS: The overall outpatient visits per month declined by 39% (rate ratio [RR], 0.61; P < .0001) after adjusting for demographics. A notable reduction in visits was observed in foreign patients (RR, 0.50; P < .0001). The visits of the elderly (≥ 80 years) were the most frequent before the COVID-19 pandemic but were reduced by 44% (RR, 0.56; P < .0001) after it began. Most disease categories revealed a declining trend, but the size of reduction varied by International Classification of Diseases codes. CONCLUSIONS: The COVID-19 pandemic prevented some individuals from keeping regular medical appointments even in an area with a low infection risk. Our findings imply that more research is required to mitigate the effects of delayed medical care for patients who infrequently utilized medical care during and after the long-lasting pandemic period.

AIM: Senior healthcare is challenging in remote areas, particularly in an economically disadvantaged population. This study examined the benefits of a combined healthcare system (Houston-Apollo model) in improvements of physical performance and medical care utilization of local older people. METHODS: People aged ≥65 years who participated in congregate meal services were recruited. Using concepts of telemedicine and community health records, participants received consultation from local general physicians, who provided advice or arranged referrals to the National Taiwan University Hospital Yunlin Branch. Physical parameters including blood pressure, body mass index, grip strength, walking speed, and five times sit-to-stand test (FTSST) were transferred to the National Taiwan University Hospital Yunlin Branch and local doctors in a timely manner. Changes in physical parameters and utilization of healthcare facilities were measured at the beginning of recruitment and 1 year later. RESULTS: In the 470 registered participants, 66% had hypertension, 50% had weakness in grip strength, 58% were slow at FTSST and 78% had disability in 6-meter walking speed. In total, 97 participants were followed up at 1 year. The systolic and diastolic blood pressure (mmHg) decreased from 137.4 to 133.3 (P = 0.019) and from 76.9 to 74.4 (P = 0.008), respectively. The time of FTSST (s) decreased from 11.3 to 10.4 (P = 0.011). The walking speed (m/s) increased from 0.71 to 0.74 (P = 0.039). Medical and dental outpatient usage increased by 2 and 1.14 times, respectively. CONCLUSIONS: The Houston-Apollo model could provide benefits for the physical status of older adults, promote proactive and preventive healthcare utilization, and contribute to medical equality.

BACKGROUND: To elucidate the impact of varying anatomic sites on advanced stage of and death from oral cancer. METHODS: A total of 27 717 oral cancers mainly from a population-based visual inspection program in Taiwan from 2004 to 2009 was followed until the end of 2012. RESULTS: Using lip cancer as reference, the odds ratios (95% confidence interval [CI]) of advanced stage of cancer were 2.20 (1.92-2.51) for tongue, 2.60 (2.28-2.97) for buccal, 2.68 (2.20-3.28) for floor of mouth, 2.96 (2.52-3.47) for hard palate, 6.04 (5.17-7.05) for gingiva, and 10.83 (9.20-12.74) for oropharynx. The estimated hazard ratios (95% CI) for oral cancer death increased from 1.48 (1.31-1.67) in buccal, 1.61 (1.43-1.82) in tongue, 1.68 (1.41-1.99) in floor of mouth, 1.79 (1.57-2.05) in gingiva, 1.97 (1.71-2.26) in hard palate, and 2.15 (1.89-2.45) in oropharynx. CONCLUSION: Different anatomic sites had variations in advanced stage of and death from oral cancer and need vigilant surveillance.

Literature regarding cardiac deaths in hemorrhagic stroke patients is few. The aim of this study was to investigate the incidence and risk factors of cardiac death in hemorrhagic stroke patients. We used the multiple causes of death database from the Centers for Disease Control and Prevention Wide-ranging Online Data of the United States. We identified death certificates from 2006 to 2010 with hemorrhagic stroke (International Classification of Disease, Tenth Revision (ICD-10) code I60-62), or ischemic stroke (ICD-10 code I63), and evaluated the frequency and risk factors of reporting MI (ICD-10 code I20-25) or arrhythmias (ICD-10 code I44-45, I47-49) as the main cause of death in these populations. Over the five-year period, 224,359 death certificates that mentioned hemorrhagic stroke were identified, and the cause of death was MI in 8.95% and arrhythmia in 7.28% patients. With autopsy confirmation, the incidences of MI and arrhythmias in the hemorrhagic stroke group were still lower than the ischemic group. The odds ratio of reporting arrhythmias as a cause of death in hospitalized population was higher. A substantial percentage of hemorrhagic stroke patients had cardiac death. Greater efforts are needed to closely monitor high-risk groups such as females and the elderly.
RESUMO
Background. Peripheral arterial disease (PAD) and its relevant complications are more common in hemodialysis (HD) patients, while the evidence regarding antiplatelet therapy in CKD patients is scarce. We retrospectively analyzed the efficacy of cilostazol on outcomes in HD patients with asymptomatic PAD (aPAD). Methods. This cohort study enrolled 217 HD patients (median follow-up time: 5.75 years). Associations between cilostazol use and the outcomes were evaluated by time-dependent Cox regression analysis. Results. During follow-up, 39.5% (47/119) patients used cilostazol for aPAD and 31.8% (69/217) patients died. Cilostazol users had significantly lower CVD and all-cause mortalities (adjusted HR [95% CI]: 0.11 [0.03, 0.51] and 0.2 [0.08, 0.52]) than nonusers. Both death risks were nonsignificantly higher in cilostazol users than in HD patients without aPAD. The unadjusted and adjusted HR [95% CI] of CVD death risk were 0.4 [0.07, 2.12] and 0.14 [0.02, 0.8] for patients with aPAD during follow-up and were 0.74 [0.16, 3.36] and 0.19 [0.04, 0.93] for those with aPAD at initial. Conclusions. In HD patients with aPAD, lower CVD and all-cause mortality rates were observed in low-dose cilostazol user. Further evidences from large-scale prospective study and randomization trial are desired to confirm the effect of cilostazol.

OBJECTIVES: To disclose the association between diabetes mellitus (DM) and cryptococcosis in HIV-uninfected patients. METHODS: Case patients' diagnoses with cryptococcosis and cryptococcal meningitis were based on data from the Taiwan National Health Insurance Research Database from 2000 to 2010, and diagnoses were defined using the International Classification of Disease, Ninth Revision, Clinical Modification. A case-control study comprising inpatient and outpatient populations was conducted using 4 controls for each patient (4587 case patients and 18,348 controls) matched for age, sex, monthly income, and urbanization level. RESULTS: Human immunodeficiency virus (HIV)-uninfected patients with cryptococcosis were more likely to have diabetes than matched control patients (adjusted odds ratio [OR], 1.45; 95% confidence interval [95% CI], 1.36-1.64; p < 0.001). A diagnosis of DM was also associated with 1-year and overall mortality from cryptococcosis (hazard ratio [HR], 1.39; 95% CI, 1.17-1.65; p < 0.001, HR, 1.47; 95% CI, 1.29-1.67; p < 0.001; respectively) and cryptococcal meningitis (p = 0.018). CONCLUSIONS: Diabetes was associated with the occurrence of cryptococcosis and cryptococcal meningitis in HIV-uninfected patients. DM was also associated with 1-year and overall mortality for these patients.

OBJECTIVE: Thyroid surgery is generally a safe surgery but its complications are still common. We wish to identify preoperative factors that predict postoperative complications. METHODS: A nationwide survey was conducted by senior surgeons from 16 medical centers and 5 regional hospitals in Taiwan to thyroid operations performed over 3 years. 3846 cases were retrospectively examined to identify factors influencing complications: indication for surgery, preoperative evaluation, such as ultrasonography, chest X-ray, computed tomography and magnetic resonance imaging, isotope scanning, fine-needle aspiration cytology (FNAC) and thyroid function test, and patient characteristics. RESULTS: Eighty-four percent of patients were female. Seven percent of the patients had immediate postoperative hypocalcemia (mild and severe) and 2.3%, hoarseness (recurrent laryngeal nerve (RLN) injury, temporary/permanent). Logistic regression analysis identified an association between hypocalcemia and RLN injury with age, hospital category, surgical procedure types (total thyroidectomy, unilateral, bilateral subtotal or total resection). A lower incidence of hypocalcemia was related to preoperative neck ultrasound and FNAC analysis (the odds ratio (OR) = 0.5 and 0.65, [95% confidence interval (CI) 0.331-0.768 and 0.459-0.911], P = 0.0014 and 0.0127, respectively), while RLN injury was not associated with any preoperative evaluation. The ORs of hypocalcemia and RLN injury for patients older than 50 years were 0.55 and 2.15, [0.393-0.763 and 1.356-3.4], P < 0.001 and 0.0012, respectively. CONCLUSIONS: The success of thyroid surgery depends on careful preoperative planning, including a preoperative neck ultrasound to determine the proximity of the nodule to the recurrent laryngeal nerve course, and the consideration of the type of anesthesia, adjuvant devices for intra-op monitoring of the RLN, and surgical modalities. Our results suggest that preoperative evaluation implementations are positively associated with strategy of surgery and postoperative hypocalcemia prevention.
RESUMO
BACKGROUND: Substantial evidence suggests that increased oxidative stress in hemodialysis (HD) patients may contribute to cardiovascular complications. Oxidative modifications of human serum albumin (HSA), the largest thiol pool in plasma, alter its biological properties and may affect its antioxidant potential in HD patients. METHODS: We conducted a long-term follow-up study in a cohort of normoalbuminemic HD patients to examine the impact of redox state of serum albumin on patients' survival by measuring the human nonmercaptoalbumin (HNA) fraction of HSA. RESULTS: After adjusting for potential demographic, anthropometric, and clinical confounders, a positive association of HNA level with the risk of death from cardiovascular disease (CVD) and all-cause mortality was observed in normoalbuminemic HD patients. Using stratified analysis, we found a stronger association between HNA level and the risk of death from CVD and all-cause mortality in patients with pre-existing CVD. CONCLUSIONS: Serum HNA level is a positive predictor of mortality in normoalbuminemic HD patients, especially among those with pre-existing CVD. Increased oxidative stress resulting from biological changes in serum albumin levels could contribute to accelerated atherosclerosis and the development of cardiovascular disease in HD patients.

The aim of this study was to apply a calibrated two-stage community-based design to estimate the prevalence of diabetic distal sensorimotor polyneuropathy (DPN) in Taiwan. Type 2 diabetics were identified from a population-based screening program in Keelung, Taiwan. Administration of the Neurological Symptom Score (NSS) questionnaire identified 210 DPN-positive cases of the 587 diabetic subjects tested. The accuracy of this NSS screening was tested with sensitive electrophysiological DPN diagnosis. A smaller validation study was also conducted to estimate the sensitivity and specificity of the NSS questionnaire. In the validation study, the overall prevalence rate for DPN among type 2 diabetics was 26.79%. The sensitivity, specificity, positive predictive value and negative predictive values were 73.33, 30.49, 24.72 and 75.76%, respectively. The estimates of sensitivity, specificity and positive predictive values were 75.00, 33.33 and 42.86% for old cases of diabetes, and 72.22, 29.69 and 22.41% for newly diagnosed cases. The range of prevalence rate in the main study was adjusted to 28.46-36.30% after calibration for sensitivity and specificity with the validation study data. A two-stage community-based screening model with calibration of prevalence rate was developed and enabled a cost-effective DPN prevalence rate estimate in a study with a large number of subjects.
