Curbing COVID-19 progression and mortality with traditional Chinese medicine among hospitalized patients with COVID-19: A propensity score-matched analysis.

BACKGROUND: Viral- and host-targeted traditional Chinese medicine (TCM) formulae NRICM101 and NRICM102 were administered to hospitalized patients with COVID-19 during the mid-2021 outbreak in Taiwan. We report the outcomes by measuring the risks of intubation or admission to intensive care unit (ICU) for patients requiring no oxygen support, and death for those requiring oxygen therapy. METHODS: This multicenter retrospective study retrieved data of 840 patients admitted to 9 hospitals between May 1 and July 26, 2021. After propensity score matching, 302 patients (151 received NRICM101 and 151 did not) and 246 patients (123 received NRICM102 and 123 did not) were included in the analysis to assess relative risks. RESULTS: During the 30-day observation period, no endpoint occurred in the patients receiving NRICM101 plus usual care while 14 (9.27%) in the group receiving only usual care were intubated or admitted to ICU. The numbers of deceased patients were 7 (5.69%) in the group receiving NRICM102 plus usual care and 27 (21.95%) in the usual care group. No patients receiving NRICM101 transitioned to a more severe status; NRICM102 users were 74.07% less likely to die than non-users (relative risk= 25.93%, 95% confidence interval 11.73%-57.29%). CONCLUSION: NRICM101 and NRICM102 were significantly associated with a lower risk of intubation/ICU admission or death among patients with mild-to-severe COVID-19. This study provides real-world evidence of adopting broad-spectrum oral therapeutics and shortening the gap between outbreak and effective response. It offers a new vision in our preparation for future pandemics.

Conspicuous Response to Direct-Acting Antivirals in Chronic Hepatitis C-related Immune Thrombocytopenia: A Case Report.

A 39-year-old man with a history of intravenous drug use was diagnosed to have a sudden onset of immune thrombocytopenia (ITP) in the background of a chronic hepatitis C infection with genotype 3a. Two courses of high-dose pulse dexamethasone therapy (40 mg daily for consecutive four days) failed to raise the platelet counts, but a combination direct-acting antiviral (DAA) regimen of sofosbuvir and velpatasvir, which had been proved to be effective for all hepatitis C virus (HCV) genotypes, successfully restored the platelets number to normal ranges after hepatitis C virus ribonucleic acid (RNA) was totally eliminated. Molecular mimicry of hepatitis C virus envelope proteins with platelet surface antigens is proposed to be the underlying cause of immune thrombocytopenia. An adequate direct-acting antiviral regimen is considered to be the most reliable therapy for hepatitis C-related immune thrombocytopenia.

Longitudinal changes in physical and mental health of older adults with chronic hepatitis B infection: Trajectories and predictors.

Despite the increasing health burden of chronic hepatitis B (CHB) in aging populations, little is known about the course of health-related quality of life (HRQoL) changes. We aimed to assess individual-level longitudinal HRQoL changes in elderly patients with CHB and to examine their correlates. A prospective 5.1 years-cohort study was conducted in community-dwelling adults aged 55 years with hepatitis B surface antigen-positive. Participants underwent serial measurement of HRQoL using the short-form (12) health survey version 2. Of 503 participants, 82.7% remained in good physical health throughout the study period, whereas 9.1% had declining physical health and 8.2% were in poor physical health. We likewise identified three trajectories of mental health changes ("good mental health" [86.9%], "declining mental health" [6.8%], and "poor mental health" [6.4%]). Three baseline characteristics were independently associated with a lower likelihood of remaining physically or mentally healthy: sarcopenic obesity (odds ratio [OR] with 95% confidence interval [95% CI] of 7.5 [2.8-20.5] for poor physical health, 3.1 [1.1-8.4] for declining physical health, 4.3 [1.4-13.0] for poor mental health), a higher number of metabolic abnormalities (OR [95% CI] of 3.6 [1.6-8.0] for poor physical health) and depressed mood (OR [95% CI] of 21.7 [5.8-81.0] for poor physical health, 5.3 [1.4-19.9] for declining physical health, 83.1 [19.7-350.2] for poor mental health, 13.6 [2.9-64.8] for declining mental health). In conclusion, in a cohort of elderly patients with CHB, we demonstrated the heterogeneity and nonlinearity of HRQoL changes and their associations with variations in specific extrahepatic organs/systems.

Paradoxical Relationship Between Glycated Hemoglobin and Longitudinal Change in Physical Functioning in Older Adults: A Prospective Cohort Study.

BACKGROUND: Hyperglycemia with high hemoglobin A1c (HbA1c) levels is associated with significant health risks. However, the relationship between HbA1c levels and the physical functioning status in later life remains uncertain and so is the possible underlying mechanism. METHODS: We conducted a prospective study of 2,565 initially well-functioning community-dwelling older adult aged 55 years and older from the Healthy Aging Longitudinal Study in Taiwan. Each participant received baseline measurements of blood HbA1c and inflammatory markers levels and repeated assessments of physical functioning over a mean follow-up period of 5.3 years. We used generalized linear mixed-effects regression to estimate the adjusted changes in the odds ratio for self-reported physical functioning impairment and Short Physical Performance Battery (SPPB) score according to baseline HbA1c levels (categorized into 0.5% increments from <5.5% to ≥7.0%). RESULTS: HbA1c levels showed a U-shaped relationship with changes in the odds ratio for physical functioning impairment and SPPB score (p for quadratic term < .001). Compared with participants with an HbA1c of 5.5% to <6.0%, those with an HbA1c of <5.5% or ≥7.0% had a higher annual increase in the odds ratio for physical functioning impairment (odds ratio [95% confidence interval] per year, 1.25 [1.04-1.50] and 1.21 [1.04-1.41]) and a higher annualized decrease in SPPB score (coefficient [95% confidence interval], -0.05 [-0.10 to 0.00] and -0.04 [-0.08 to 0.00]). These relationships were nonlinear only in participants with high soluble interleukin-6 receptor levels (>48,124 pg/mL; p for interaction < .05). CONCLUSIONS: High and low HbA1c levels at baseline are associated with faster physical functioning decline, particularly among individuals with elevated circulating soluble interleukin-6 receptor, a sign of enhanced interleukin-6 trans-signaling.

Comparisons of clinical impacts on individuals with Brugada electrocardiographic patterns defined by ISHNE criteria or EHRA/HRS/APHRS criteria: a nationwide community-based study.

INTRODUCTION: Identifying Brugada electrocardiographic pattern (BrP) early is crucial to prevent sudden cardiac death. Two different diagnostic criteria proposed by International Society for Holter and Noninvasive Electrocardiography (ISHNE) and Heart Rhythm Society/European Heart Rhythm Association/Asia-Pacific Heart Rhythm Society (HRS/EHRA/APHRS) were widely used in clinical practice. The difference in prevalence and prognosis of BrP by applying the two different criteria was never studied before. METHODS: This study was prospectively conducted in a nationwide large-scale stratified random sampling community-based cohort (HALST) from Han Chinese population in Taiwan from December 2008 to December 2012. We compared the prevalence and prognosis of BrP defined by the two diagnostic criteria. RESULTS: A total of 5214 adults were enrolled (2530 men) with mean age of 69.3 years. Four had spontaneous type 1 BrP (0.077%). By the HRS/EHRA/APHRS criteria, 68 individuals have type 2 BrP (1.30%) and 101 have type 3 BrP (1.94%) whereas by the ISHNE criteria, 46 individuals exhibited type 2 BrP (0.88%). When applying the ISHNE criteria, the number of individuals with BrP decreased by 71%. However, all-cause mortality and cardiovascular mortality were not different between individuals with or without BrP, irrespective of the criteria used. CONCLUSIONS: The two different criteria may impact the diagnostic yield of individuals with BrP, but do not affect the prognosis of the individuals with BrP. Key messages Comparing with the use of HRS/EHRA/APHRS criteria, the number of individuals with Brugada ECG patterns was decreased by 71% when applying the ISHNE criteria. The prognosis of individuals with Brugada ECG patterns defined by 2012 ISHNE or 2013 HRS/EHRA/APHRS criteria were not different.

Healthy lifestyle and normal waist circumference are associated with a lower 5-year risk of type 2 diabetes in middle-aged and elderly individuals: Results from the healthy aging longitudinal study in Taiwan (HALST).

Type 2 diabetes mellitus (DM) is known to be closely associated with lifestyle and obesity and has a prevalence that increases with age. This study aimed to assess the short-term composite effect of diet, physical activity, psychosocial health, and waist circumference (WC) on the incidence of DM in the elderly and to provide a lifestyle-based predictive index.We used baseline measurements (2009-2013) of 5349 community-dwelling participants (aged 55 years and older, 52% female) of the Healthy Aging Longitudinal Study in Taiwan (HALST) for fasting plasma glucose, HbA1C, serum cholesterol, triglycerides, blood pressures, WC, and outcomes of home-visit questionnaire. Principal component analysis (PCA) was used to identify participants with a healthy lifestyle (HLF: higher diet, physical activity, and psychosocial scores) and a lower WC, with cutoffs determined by the receiver-operating characteristics. A Cox regression model was applied to 3424 participants without DM at baseline by linking to their National Health Insurance records (median follow-up of 3.1 years).In total, 247 new DM cases (7.2%) were identified. The HLF and lower WC group had a relative risk (RR) of DM of 0.54 (95% CI 0.35-0.82) compared to the non-HLF and higher WC group. When stratified by the presence of impaired glucose tolerance (IGT) or metabolic syndrome (MS), only participants with IGT/MS showed significant risks (RR 0.55; 95% CI 0.33-0.92). However, except for WC, the individual lifestyle factors were nonsignificant in the overall model without PCA.A composite protective effect of HLF and normal WC on DM within 5 years was observed, especially in those with IGT or MS. Psychosocial health constituted an important lifestyle factor in the elderly. The cutoffs identified could be used as a lifestyle-based risk index for DM. Maintaining an HLF to prevent DM is especially important for the elderly.

Unplanned emergency department revisits within 72 hours to a secondary teaching referral hospital in Taiwan.

BACKGROUND: When patients return to the emergency department (ED) shortly after being seen, it is generally assumed that their initial evaluation or treatment was inadequate. OBJECTIVES: The purpose of this study was to determine the rates and causes of revisits to the ED of a 710-bed secondary teaching referral hospital (Kuang Tien General Hospital), to identify areas for improvement, and to define the initial ED presentations that are associated with such revisits. METHODS: The study period was from January 1, 2006 to December 31, 2006. There were 34,714 patients seen and discharged in the ED; 1899 patients returned within 72 h. Monthly revisit rates were calculated. The patients who revisited the ED within 72 h were retrospectively identified by the authors, and their charts were examined to determine the causes of the revisits. RESULTS: There were 1899 patients (5.47% of total) found to have revisited the ED within 72 h after their initial visit. The monthly revisit rates ranged from 2.85% to 6.25% (average, 5.47%). The rates of revisits that were related to factors of illness, patients, and doctors were 80.9%, 10.9%, and 8.2%, respectively. Among the factors related to doctors, 3.7% (70 cases) were misdiagnosis, and abdominal pain was the most common presentation (55.7%, 39/70). The most common initial ED presentations were for abdominal pain (12.9%), fever (12.6%), vertigo (4.5%), headache (2.1), and upper respiratory infection (2.1%). CONCLUSIONS: Unplanned ED revisits are associated with medical errors in prognosis, treatment, follow-up care, and information. Differentiation between the natural course of a disease, suboptimal therapy, over-anxious reaction of the patient, and medical errors is difficult. Although this study indicates that most revisits are illness-related, further prospective studies are needed to evaluate the most common and the most serious causes of revisits to see if improvements can be made.
