RESUMO
BACKGROUND: For people with human immunodeficiency virus (PWH) who have no serological responses to their primary hepatitis A virus (HAV) vaccination or have seroreversion after successful primary vaccination, the optimal revaccination strategy remains unclear. METHODS: In this open-label, randomized clinical trial, PWH who tested negative for anti-HAV antibodies after receiving a standard 2-dose series of primary HAV vaccination were enrolled and assigned in a 1:1 ratio to receive either 1 dose (the 1-dose group) or 2 doses of HAV vaccine administered 4 weeks apart (the 2-dose group). Serological response rates and anti-HAV antibody titers were compared at weeks 24 and 48. RESULTS: Of the 153 participants (77 in the 1-dose group and 76 in the 2-dose group), the overall serological response rates at week 48 after revaccination were similar between the 2 groups (2- vs 1-dose, 80.2% vs 71.4%, P = .20). However, anti-HAV antibody titers were consistently higher in the 2-dose group than in the 1-dose group. In subgroup analysis, PWH who were nonresponders to primary HAV vaccination were significantly more likely to mount a serological response after 2-dose HAV revaccination (68.4% vs 44.1%, P = .038). No severe adverse events were reported throughout the study. CONCLUSIONS: Two-dose HAV revaccination administered 4 weeks apart yielded similar serological responses as 1-dose revaccination among PWH who were nonresponders or had seroreversion after primary HAV vaccination. The 2-dose revaccination schedule generated significantly higher anti-HAV antibody titers and was more likely to elicit serological responses at week 48 among PWH who were nonresponders to primary HAV vaccination.

AIMS: To develop and psychometrically test Character Strengths Use in Diabetes Self-management Scale in people with type 2 diabetes. DESIGN: Cross-sectional design. METHODS: Based on literature reviews and examination by experts, a 20-item scale was developed and administered to 350 participants with type 2 diabetes who were enrolled from two endocrine clinics by convenience sampling in Taiwan. Item analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), concurrent and predictive validity as well as reliability were used to examine the psychometric characteristics of the scale. Data were collected from November 2021 to March 2022. RESULTS: EFA and CFA supported a 12-item scale with three factors, namely learning proactively, taking on challenges and thinking positively, fit the data well. The total score of the 12-item scale significantly and positively correlated with diabetes-specific quality of life, and significantly and negatively correlated with baseline and 9-month haemoglobin A1c levels. Cronbach's α for overall scale and subscales ranged between .78 and .91. CONCLUSION: The 12-item Character Strengths Use in Diabetes Self-management Scale demonstrated satisfactory validity and reliability in people with type 2 diabetes. IMPACT: Nurses could apply this new scale to identify the degree of using character strengths in self-management in people with type 2 diabetes; accordingly, character strength-based interventions could be provided to improve self-management in such patients with diabetes. Furthermore, the 12-item Character Strengths Use in Diabetes Self-management Scale has the potential to be used to measure the effectiveness of strength-based interventions in people with Type 2 diabetes. PATIENT OR PUBLIC CONTRIBUTION: Five patients with type 2 diabetes were invited to take the original 20-item scale to evaluate the clarity, readability and comprehensiveness of the 20 items.

BACKGROUND: The Hippo pathway is conserved through evolution and plays critical roles in development, tissue homeostasis and tumorigenesis. Yes-associated protein (YAP) is a transcriptional coactivator downstream of the Hippo pathway. Previous studies have demonstrated that activation of YAP promotes proliferation in the developing brain. Whether YAP is required for the production of neural progenitor cells or neurons in vivo remains unclear. RESULTS: We demonstrated that SATB homeobox 2 (SATB2)-positive projection neurons (PNs) in upper layers, but not T-box brain transcription factor 1-positive and Coup-TF interacting protein 2-positive PNs in deep layers, were decreased in the neonatal cerebral cortex of Yap conditional knockout (cKO) mice driven by Nestin-Cre. Cell proliferation was reduced in the developing cerebral cortex of Yap-cKO. SATB2-positive PNs are largely generated from intermediate progenitor cells (IPCs), which are derived from radial glial cells (RGCs) during cortical development. Among these progenitor cells, IPCs but not RGCs were decreased in Yap-cKO. We further demonstrated that cell cycle re-entry was reduced in progenitor cells of Yap-cKO, suggesting that fewer IPCs were generated in Yap-cKO. CONCLUSION: YAP is required for the production of IPCs and upper-layer SATB2-positive PNs during development of the cerebral cortex in mice.

BACKGROUND: With initiation of antiretroviral therapy (ART) containing nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) with anti-hepatitis B virus (HBV) activity, the evolution of HBV serologic markers among people living with human immunodeficiency virus (PLWH) who were born in the era of nationwide neonatal HBV vaccination is rarely investigated. METHODS: This retrospective cohort study evaluated the changes of HBV serologic markers (hepatitis B surface antigen [HBsAg], antibody to hepatitis B surface antigen [anti-HBs], and antibody to hepatitis B core antigen [anti-HBc]) of PLWH who had undergone neonatal HBV vaccination. Clinical characteristics were analyzed and the incidences of evolution of HBV serologic markers were estimated. RESULTS: Between 2004 and 2020, 608 PLWH (mean age, 24 years) were included and 62.0% initiated tenofovir-containing ART: 13 (2.1%) were HBsAg-positive, 312 (51.3%) tested triple-negative, 209 (34.4%) had vaccine-induced seroprotection against HBV, and 74 (12.2%) tested positive for anti-HBc with or without anti-HBs. Among 492 PLWH who received a median follow-up of 2.8 years, 4 cases of incident HBV infection occurred (0.59 per 100 person-years of follow-up [PYFU]) in PLWH testing triple-negative at baseline despite ART containing NRTIs with anti-HBV activity. Of PLWH with seroprotection against HBV at baseline, 38 subsequently lost anti-HBs (4.46 per 100 PYFU) and 4 cases of incident HBV infection occurred (0.47 per 100 PYFU). PLWH with an anti-HBs antibody titer ≥100 mIU/mL at baseline (adjusted hazard ratio [aHR], 0.10 [95% confidence interval {CI}: .02-.42]) and CD4 ≥500 cells/µL during follow-up (aHR, 0.51 [95% CI: .30-1.00]) were less likely to lose HBV seroprotection. CONCLUSIONS: Among young PLWH who had undergone neonatal HBV vaccination, evolution of HBV serologic markers and incident infections occurred despite ART containing NRTIs with anti-HBV activity.

PURPOSE: This study aimed to explore the experience and views of mothers with children who have been diagnosed with retinoblastoma. DESIGN AND METHODS: A descriptive qualitative study was conducted in the period of 2019-2021. Interviews were conducted with 21 mothers of children diagnosed with retinoblastoma in Indonesia. Data were collected by semi-structured interviews and examined by content analysis. RESULTS: Mothers evolved from a sense of unacceptability to accepting challenges and gaining inner strength. Three themes were identified: 1) physical and psychological suffering, 2) awareness of changes and demands, and 3) keep moving forward. Mothers developed positive adaptive mechanisms for coping with the problems associated with having a child with retinoblastoma. Psychological adjustment and religious beliefs were key elements in their journeys toward embracing life in the moment. CONCLUSION: Findings illuminated psychological adaptation and coping strategies of mothers with seriously ill children and highlighted how difficulties and cultural norms shaped the adaptative process. Religion and health beliefs played varied and important roles in helping mothers to manage their stress and enhance their coping strategies. PRACTICE IMPLICATIONS: Our findings revealed that it is important to routinely assess social support, traditional health beliefs, and spirituality on mothers, facilitate mentoring to help mothers find their inner strengths, and develop intervention programs designed to promote psychological adjustment without delaying treatment.

Hepatitis A virus (HAV) and hepatitis E virus (HEV) share the similar fecal-oral transmission route. During an outbreak of sexually transmitted acute hepatitis A among men who have sex with men (MSM) worldwide between 2015 and 2017, we investigated the possibility of sexual transmission and related morbidity of HEV infection among human immunodeficiency virus (HIV)-positive patients. From March 1, 2015 to August 31, 2017, anti-HEV immunoglobulin G was retrospectively determined among 3,293 HIV-positive patients, who were mainly MSM (87.6%) with a median CD4 count of 575 cells/µL. Prevalence and incidence of HEV infection were 3.7% (123 of 3,293) and 4.35 per 1,000 person-years of follow-up (PYFU), respectively, which were significantly lower compared with those of HAV infection (31.1% [996 of 3,204] and 12.61 per 1,000 PYFU, respectively). The number of patients with HEV infection did not increase with the hepatitis A epidemic. The factor associated with prevalent HEV infection was older age (per 1-year increase, adjusted odds ratio, 1.07; 95% confidence interval, 1.05-1.09), but neither sexual orientation nor acquisition of sexually transmitted infections was related to prevalent or incident HEV infection. Among 23 patients with incident HEV infection, 22 patients had viremia caused by HEV genotype 4. No patients had prolonged HEV viremia or clinical symptoms, and only a mild elevation of serum aminotransferase, ranging from 34 to 77 IU/L, was noted. Although 4 patients had hepatitis for a prolonged duration of between 8 and 17 months, no abdominal imaging revealed liver fibrosis or cirrhosis. Conclusion: HEV endemicity remained low among HIV-positive patients in Taiwan during the outbreak of acute hepatitis A. Our data suggest that sexual transmission of HEV with significant morbidity of HEV infection, if any, is rare in this population.

BACKGROUND: Higher rates of hepatitis C virus (HCV) reinfection after viral clearance have been well described among HIV-positive men who have sex with men (MSM) in Europe. The epidemiology of HCV reinfection, however, has rarely been investigated among HIV-positive patients in Asia-Pacific region. METHODS: We retrospectively identified HIV-positive patients with recent HCV infection who had cleared their primary infection, either spontaneously or via treatment, between January 2011 and May 2018. All included patients were observed until 31 March 2019. HCV reinfection was defined as recurrent HCV viraemia after achieving viral clearance with anti-HCV treatment or after spontaneous clearance. RESULTS: During the study period, 219 HIV-positive patients (90.4% MSM) were diagnosed with recent HCV infection. Viral clearance with successful treatment was achieved in 108 patients (49.3%) and spontaneous clearance occurred in 20 (9.1%); of them, 18 (14.1%) acquired HCV reinfections, resulting in an incidence rate of 8.2 per 100 person-years of follow-up (95% CI 5.2-13.1). With the adjusted Cox proportional hazards model, we found a higher reinfection risk in patients with syphilis (adjusted hazard ratio 10.3, 95% CI 1.4-77.8, P = .023) compared to those without syphilis. HCV RNA testing, if performed only following syphilis and elevated aminotransferases, might miss 44.4% and 33.3% of HCV reinfections, respectively. CONCLUSIONS: Similar to the findings in Europe, we observed a high incidence of HCV reinfection among HIV-positive Taiwanese with recent HCV infection, which was significantly associated with syphilis. To identify HCV reinfections, annual HCV RNA testing should be instituted instead of testing driven by symptoms, syphilis or elevated aminotransferases.

Complete heart block (CHB) and acute renal infarction (ARI) are both uncommon diseases and seldom encountered in the clinical practice. We describe a rare case of pre-existing left bundle branch block, presenting simultaneously with CHB and ARI. The possible mechanism depends on prior presence of either CHB or ARI. If ARI occurs first, severe pain and embolism may enhance the vagal tone resulting in decrease in the heart rate and transient intraventricular conduction interruption, which subsequently causes CHB. The opposite scenario, CHB preceding ARI, is also possible. CHB can be physiologic and transient, with higher risk of development in the circumstance of pre-existing conduction system disturbances. Patients with CHB are predisposed to formation of thrombi and thromboemboli, giving rise to ARI. In conclusion, awareness and timely identification of the clinical manifestations of these two diseases may facilitate early diagnosis and prompt management.

OBJECTIVE: To evaluate the impact of a transcutaneous electrical nerve stimulation (TENS) program for hemodialysis on patients' dry mouth and salivary flow rates. SUBJECTS AND METHODS: A single-blinded repeated measures study design was used. A total of 80 subjects were randomly assigned to a treatment group receiving a 250 µs; 50 Hz TENS program and a control group receiving a 50 µs; 2 Hz TENS program at acupoints ST 6 and TE17 three times a week for 3 weeks. Whole salivary flow rate and dry mouth intensity were measured totally five times for both groups, at pretreatment, after three, six, nineTENS sessions, and 1 week after the treatment was completed. RESULTS: After six TENS sessions were completed, whole salivary flow rates increased stably until the end of nine TENS sessions for the treatment group. In the follow-up week after treatment, there was significant increase as well. However, significant improvement in dry mouth intensity was observed at all post-tests than that at pretreatment in both groups. CONCLUSION: Whole salivary flow rates and improvement in dry mouth intensity were only observed during and 1 week after the TENS sessions. Further studies are needed to evaluate whether this method can offer a long-term effective nonpharmacological therapy for dry mouth-disturbed hemodialysis patients.

BACKGROUND: Serological responses to revaccination against hepatitis B virus (HBV) are unclear in HIV-positive adults who had undergone neonatal HBV vaccination and whose antibodies against HBV had waned in the era of combination antiretroviral therapy (cART). METHODS: Between 2000 and 2017, 666 HIV-positive men who have sex with men (MSM) who were born after 1986, when nationwide neonatal HBV vaccination programme was implemented in Taiwan, were included for analyses. A serological response was defined when a hepatitis B surface antibody (anti-HBs) titre ≥10 mIU/mL was measured 4-24 weeks after the third dose of HBV vaccination. RESULTS: During the study period, 295 (48.7%) HIV-positive MSM (mean age, 23.2 years) who had lost HBV seroprotection were eligible for revaccination; 171 (58.0%) received at least 1 dose (20-µg) of HBV vaccine and 116 (39.3%) completed the 3-dose schedule. The serological response rate to 3 doses of HBV revaccination was 74.0% and the rate of high-titre response (anti-HBs titre ≥100 mIU/mL) was 46.0%. The CD4 count before the first dose (per 50-cell/µL increment, adjusted odds ratio, 1.14; 95% confidence interval, 1.01-1.29) was positively associated with the serological response. The incident rate of HBV infection was 9.2 per 1000 person-years of follow-up among the patients who were non-responders after revaccination. CONCLUSIONS: Despite HBV vaccination in the neonatal period, the serological response rate to HBV revaccination in HIV-positive MSM was modest and could wane rapidly. Regular testing of anti-HBs should be integrated into the HIV care despite cART containing HBV-active agents.

Background: Previous studies have shown that the durability of serological response is impaired in successfully vaccinated human immunodeficiency virus-1 (HIV-1) positive subjects after receiving 2 doses of inactivated hepatitis A virus (HAV) vaccine. We evaluated whether 3 doses compared with 2 doses of HAV vaccine could improve the long-term seroprotection for this susceptible group. Methods: Antibody persistence among HIV-positive men who have sex with men aged 18-40 years who had received 2 or 3 doses of HAV vaccine according to a 0-6- or a 0-1-6-month schedule was evaluated biannually for 5 consecutive years in this prospective, nonrandomized cohort study. Results: At the end of 5 years, seroprotection persisted in 79% (146/185) versus 76% (85/110) and 94% (146/155) versus 88% (84/95) of the 3- versus 2-dose primary responders by intention-to-treat and per-protocol analyses, respectively (P > .05). Throughout the 5 years, the geometric mean concentrations of anti-HAV immunoglobulin G (IgG) were significantly higher for the 3-dose than the 2-dose group. In the multivariable analysis, a 3-dose regimen compared with a 2-dose regimen (odds ratio = 3.36; 95% confidence interval = 1.14-9.93) was independently associated with sustained seroprotection. Conclusions: Three doses versus 2 doses of HAV vaccine improve the durability of immune responses in terms of higher concentrations of specific IgG, which take longer to decay to subthreshold levels.

BACKGROUND: Genotypic drug resistance testing for HIV-1 has been integrated into voluntary counselling and testing (VCT) programmes to investigate the trends of transmitted drug resistance (TDR), including integrase mutations, among individuals with recent or chronic HIV infections in Taiwan. METHODS: Between 2006 and 2014, 745 of 21â886 subjects (3.4%) tested HIV positive in the VCT service. The BED assay was used to identify recent HIV infections. Genotypic resistance mutations were interpreted using the WHO 2009 list. Integrase resistance mutations were analysed using the Stanford HIV Drug Resistance Database. RESULTS: Three-hundred-and-sixty (48.3%) patients were recently infected with HIV-1. Of 440 patients linked to HIV care with analysable reverse transcriptase and protease genes, 49 (11.1%) were infected with HIV-1 harbouring at least one resistance-associated mutation (RAM). The prevalence of TDR to NRTIs, NNRTIs and PIs was 4.1%, 6.4% and 2.3%, respectively. TDR prevalence did not change significantly during the study period. CD4 counts ≤500 cells/mm(3) and hepatitis B surface antigen positivity were independent factors associated with acquiring drug-resistant HIV. The prevalence of integrase mutations was 3.2%. Among the seven major integrase mutations (T66I, E92Q, G140S, Y143C/H/R, S147G, Q148H/K/R and N155H), only one strain harbouring the Q148R mutation was detected. We found no statistically significant difference between patients with chronic infection and those with recent infection in the prevalence of drug-resistant mutations to any of the four classes of antiretroviral agents. CONCLUSIONS: The prevalence of TDR of HIV-1 strains to available antiretroviral agents is moderately high, but transmission of HIV-1 with drug-resistant mutations remains stable in Taiwan.

BACKGROUND: Superinfection with hepatitis D virus (HDV) may increase the risk for hepatitis flares and chronic hepatic complications in patients with chronic hepatitis B virus (HBV) infection. This retrospective observational study aimed to examine the incidence of and factors associated with recent HDV superinfection among individuals coinfected with human immunodeficiency virus (HIV) and HBV. METHOD: Anti-HDV immunoglobulin G (IgG) was sequentially determined in 375 HIV/HBV-coinfected patients to estimate the HDV incidence between 1992 and 2012. Plasma HDV and HBV loads and HBV surface antigen (HBsAg) levels were determined for the HDV seroconverters. A nested case-control study was conducted to identify the associated factors with HDV seroconversion. Phylogenetic analysis was performed using HDV sequences amplified from HDV seroconverters and HDV-seropositive patients at baseline. RESULTS: During 1762.4 person-years of follow-up [PYFU], 16 patients seroconverted for HDV, with an overall incidence rate of 9.07 per 1000 PYFU, which increased from 0 in 1992-2001, to 3.91 in 2002-2006, to 13.26 per 1000 PYFU in 2007-2012 (P < .05). Recent HDV infection was associated with elevated aminotransferase and bilirubin levels and elevated rapid plasma reagin titers. Of the 12 patients with HDV viremia, 2 were infected with genotype 2 and 10 with genotype 4. HBsAg levels remained elevated despite a significant decline of plasma HBV DNA load with combination antiretroviral therapy that contained lamivudine and/or tenofovir. CONCLUSIONS: Our findings show that the incidence of recent HDV infection in HIV/HBV-coinfected patients increased significantly from 1992-2001 to 2007-2011, and was associated with hepatitis flares and syphilis.

OBJECTIVES: We aimed to investigate the evolution of weight, lipid profiles, and glucose homeostasis among virally suppressed people with HIV (PWH) who switched to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). METHODS: PWH with viral suppression who switched to BIC/FTC/TAF in Taiwan between October 2019 and May 2021 were followed for 96 weeks to examine changes in weight, lipid profiles (total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG)), and glycated hemoglobin (HbA1c) levels. RESULTS: 889 PWH with an average weight of 72.1 kg at baseline were included. At week 96, more than 95% of PWH consistently maintained plasma HIV RNA load <50 copies/mL at each 24-week interval of follow-up, while the weight change was small (+0.7 kg, P < 0.0001), although statistically significant. Baseline levels of TC, LDL-C, HDL-C, TG, and HbA1c were 191.8 mg/dL, 114.2 mg/dL, 48.9 mg/dL, 174.3 mg/dL, and 5.31%, respectively. After 96 weeks, changes were observed in TC (-11.6 mg/dL, P < 0.0001), LDL-C (-3.4 mg/dL, P = 0.0084), HDL-C (+0.6 mg/dL, P = 0.1089), TG (-30.2, P < 0.0001), and HbA1c (+0.12%, P < 0.0001). A 5% or more weight gain was associated with age of 30-40 years, normal weight at baseline, and prior use of non-integrase inhibitors or tenofovir disoproxil fumarate. Obesity was associated with development of both dyslipidaemia and diabetes mellitus after switch. CONCLUSIONS: Stable switch to BIC/FTC/TAF maintained high rates of viral suppression and had a small effect on weight and metabolic changes in virally suppressed PWH. Follow-up of the weight and metabolic changes is warranted in PWH on long-term antiretroviral therapy.

BACKGROUND: Mycoplasma genitalium is an emerging etiology of sexually transmitted infections (STIs) with increasing resistance to antimicrobials. Surveillance on the epidemiology of M. genitalium infection and antimicrobial resistance is warranted. METHODS: Between September 2021 and August 2023, people with HIV (PWH) and people without HIV (PWoH) at risk of STIs were screened for M. genitalium infection using a multiplex polymerase-chain-reaction assay of specimens collected from the rectum, urethra, oral cavity, and vagina. The prevalences of resistance-associated mutations (RAMs) of M. genitalium to fluoroquinolones, macrolides, and tetracycline were investigated. RESULTS: During the 2-year study period, 1021 participants were enrolled, including 531 PWH and 490 PWoH. Overall, 83 (8.1%) and 34 (7.6%) participants had M. genitalium infection at baseline and during follow-up, respectively, with the rectum being the most common site of detection (61.5%). With the first course of antimicrobial treatment, 27 of 63 (42.9%) participants with M. genitalium infection were cured during follow-up, including 24 of 58 (41.4%) who received doxycycline monotherapy. The prevalence of RAMs to macrolides, fluoroquinolones, and tetracyclines at baseline were 24.3%, 22.4%, and 7.9%, respectively. Though PWH had more M. genitalium infection (10.2% vs 5.9%, p = 0.01), a higher rate of RAMs to macrolides (41.0% vs 14.7%, p < 0.01) was found in PWoH. CONCLUSIONS: Among high-risk populations, the prevalence of M. genitalium infection was 8.1%. The overall genotypic resistance of M. genitalium to macrolides and fluoroquinolones was moderately high in Taiwan.

BACKGROUND: Real-world vaccine effectiveness following the third dose of vaccination against SARS-CoV-2 remains less investigated among people with HIV (PWH). METHODS: PWH receiving the third dose of BNT162b2 and mRNA-1273 (either 50- or 100-µg) were enrolled. Participants were followed for 180 days until the fourth dose of COVID-19 vaccination, SARS-CoV-2 infection, seroconversion of anti-nucleocapsid IgG, death, or loss to follow-up. Anti-spike IgG was determined every 1-3 months. RESULTS: Of 1427 participants undergoing the third-dose COVID-19 vaccination, 632 (44.3%) received 100-µg mRNA-1273, 467 (32.8%) 50-µg mRNA-1273, and 328 (23.0%) BNT162b2 vaccine and the respective rate of SARS-CoV-2 infection or seroconversion of anti-nucleocapsid IgG was 246.1, 280.8 and 245.2 per 1000 person-months of follow-up (log-rank test, p = 0.28). Factors associated with achieving anti-S IgG titers >1047 BAU/mL included CD4 count <200 cells/mm3 (adjusted odds ratio [aOR], 0.11; 95% CI, 0.04-0.31), plasma HIV RNA >200 copies/mL (aOR, 0.27; 95% CI, 0.09-0.80), having achieved anti-spike IgG >141 BAU/mL within 3 months after primary vaccination (aOR, 3.69; 95% CI, 2.68-5.07), receiving BNT162b2 vaccine as the third dose (aOR, 0.20; 95% CI, 0.10-0.41; reference, 100-µg mRNA-1273), and having previously received two doses of mRNA vaccine in primary vaccination (aOR, 2.46; 95% CI, 1,75-3.45; reference, no exposure to mRNA vaccine). CONCLUSIONS: PWH receiving different types of the third dose of COVID-19 vaccine showed similar vaccine effectiveness against SARS-CoV-2 infection. An additional dose with 100-µg mRNA-1273 could generate a higher antibody response than with 50-µg mRNA-1273 and BNT162b2 vaccine.

This study aims to examine the effectiveness of chair yoga therapy on improving functional status and daily life activity scores in older female adults with knee osteoarthritis living in the community. A quasi-experimental design was adopted. In total, 85 female participants with knee osteoarthritis were assigned to the chair yoga therapy intervention group (n = 43) or the comparison (n = 42) group. A 12-week chair yoga exercise program was provided to the intervention group two times per week from January to April 2020. The primary outcomes, which include changes in physical functional ability, body mass index, and biophysiological indicators, were evaluated for all participants in the pre- and post-measures time periods. The analysis shows that the participants had a significantly higher level of functional fitness and daily life activity scores after the chair yoga intervention. This finding indicates that the chair yoga program was effective in improving the functional fitness and daily life activity scores of community-dwelling elderly females with knee osteoarthritis.
RESUMO
BACKGROUND: While some evidence has suggested the benefits of co-formulated bictegravir, emtricitabine and tenofovir alafenamide (B/F/TAF) in improving the quality of life of people living with HIV (PLWH), patient-reported outcome studies that focus on Asian population remain scarce. We aimed to determine the changes in HIV-related symptom burden in virally-suppressed PLWH switching to B/F/TAF in a real-world setting. METHODS: PLWH on stable antiretroviral therapy (ART) for ≥6 months with plasma HIV RNA <200 copies/mL who decided to switch to B/F/TAF were eligible for the study. Participants' experience with 20 symptoms were assessed using HIV Symptom Index at baseline and weeks 24 and 48. Responses were dichotomized in two ways: 1) present vs. not present; and 2) bothersome vs. not bothersome, and compared across time points. RESULTS: Six hundred and thirty participants (prior regimen, 94.4% integrase inhibitor-based) who completed week 48 visit were included in the analysis. Forty-eight weeks after switching to B/F/TAF, six symptoms were significantly less prevalent, and seven symptoms were significantly less bothersome. Improvement was more pronounced in participants whose prior regimen was elvitegravir-based versus dolutegravir-based. Logistic regression results showed that prior dolutegravir-based ART and pre-existing diabetes independently predicted improvement in diarrhea/loose bowels and muscle aches/joint pain, respectively. Despite the overall improvement, some symptoms persisted in a substantial proportion of participants. CONCLUSIONS: Virally-suppressed PLWH might benefit from a regimen switch to B/F/TAF to reduce the prevalence and level of bother of HIV-related symptoms. Nevertheless, additional multidisciplinary interventions are warranted to further alleviate the symptom burden of PLWH.

BACKGROUND: Antiretroviral regimens containing a second-generation integrase strand-transfer inhibitor (INSTI) plus 2 nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) are the recommended therapy for people with HIV (PWH) who are antiretroviral-naïve or on stable antiretroviral therapy (ART) with viral suppression. Real-world data on the virologic effectiveness of co-formulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) among PWH with virologic failure while receiving other ART remain sparse. METHODS: We retrospectively reviewed the medical records of PWH who had viral rebound with plasma HIV RNA >1000 copies/mL and were switched to either dolutegravir combined with 2 NRTIs or BIC/FTC/TAF. The primary end point was re-achieving viral suppression within the first 48 weeks of switch. The association between NRTI-related resistance-associated mutations (RAMs) and virologic effectiveness was examined. RESULTS: Seventy-nine PWH with viral rebound while receiving other antiretroviral regimens were included. Within the first 48 weeks of switch, the overall probability of re-achieving viral suppression was 79.7% (82.5% [33/40] and 76.9% [30/39] for BIC/FTC/TAF and dolutegravir-based regimens, respectively, p = 0.78). PWH with a higher CD4 lymphocyte count (adjusted odds ratio, per 100-cell/mm3 increase, 1.41; 95% confidence interval, 1.02-1.95) were more likely to re-achieve viral suppression. Among PWH switching to BIC/FTC/TAF who had pre-existing RAMs to NRTIs before switch, 14 of 15 (93.3%) successfully achieved viral suppression. CONCLUSIONS: Switching to BIC/FTC/TAF and dolutegravir-based regimens could re-achieve viral suppression in four-fifth of the PWH who experienced viral rebound during treatment with other antiretroviral regimens. Pre-existing NRTI-related RAMs did not have adverse impact on the effectiveness of dolutegravir combined with 2 NRTIs or BIC/FTC/TAF.
