• Our findings suggest that viral load is positively correlated with disease severity when symptomatic individuals compared to asymptomatic individuals. • The length of hospital stays was directly proportional to viral load, particularly for those in the severe group. • The Cobas SARS-CoV-2 Duo assay provides a commutable unitage IU/mL for interlaboratory interpretations. The viral load (VL) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals is critical for improving clinical treatment strategies, care, and decisions. Several studies have reported that the initial SARS-CoV-2 VL is associated with disease severity and mortality. Cycle threshold (Ct) values and/or copies/mL are often used to quantify VL. However, a multitude of platforms, primer/probe sets of different SARS-CoV-2 target genes, and reference material manufacturers may cause inconsistent interlaboratory interpretations. The first International Standard for SARS-CoV-2 RNA quantitative assays has allowed diagnostic laboratories to transition SARS-CoV-2 VL results into international units per milliliter (IU/mL). The Cobas SARS-CoV-2 Duo quantitative assay provides VL results expressed in IU/mL. We enrolled 145 and 50 SARS-CoV-2-positive, hospitalized and 50-negative individuals at the Tri-Service General Hospital, Taiwan from January to May 2022. Each participant's electronic medical record was reviewed to determine asymptomatic, mild, moderate, and severe cases. Nasopharyngeal swabs were collected using universal transport medium. We investigated the association of SARS-CoV-2 VL with disease severity using the Cobas SARS-CoV-2 Duo quantitative assay and its functionality in clinical assessment and decision making to further improve clinical treatment strategies. Limit of detection (LOD) was assessed. All 50 SARS-CoV-2-negative samples confirmed negative for SARS-CoV-2, demonstrating 100 % specificity of the Cobas SARS-CoV-2 Duo assay. Patients with severe symptoms had longer hospital stays, and the length of hospital stay (30.56 days on average) positively correlated with the VL (8.22 ± 1.21 log 10 IU/mL). Asymptomatic patients had the lowest VL (5.54 ± 2.06 log 10 IU/mL) at admission and the shortest hospital stay (14.1 days on average). VL is associated with disease severity and duration of hospitalization; therefore, its quantification should be considered when making clinical care decisions and treatment strategies. The Cobas SARS-CoV-2 Duo assay provides a commutable unitage IU/mL for interlaboratory interpretations. [ABSTRACT FROM AUTHOR]

Background: Frailty and sarcopenia are geriatric syndromes of increasing concern and are associated with adverse health outcomes. They are more prevalent among long-term care facility (LTCF) users than among community dwellers. Exercise, especially multicomponent and progressive resistance training, is essential for managing these conditions. However, LTCFs, particularly in rural areas, face challenges in implementing structured exercise programs due to health care professional shortages. Moreover, older adults often become bored with repetitive exercise training and may lose interest over time. The Nintendo Switch Ring Fit Adventure (RFA) exergame is a novel exergame that combines resistance, aerobic, and balance exercises and offers a potential solution by boosting motivation in an immersive manner and reducing staff intervention needs., Objective: We aimed to evaluate the clinical effectiveness of an exergame-based exercise training program delivered via RFA (exergame-RFA) in improving muscle mass and functional performance among older adult LTCF users., Methods: This was a randomized controlled trial conducted from August 2022 to September 2023 and involved older adult LTCF users (aged ≥60 y) in rural southern Taiwan. Participants were randomized into an intervention group (exergame-RFA plus standard care) or a control group (standard care alone). The intervention, conducted seated with arm fit skills and trunk control exercises using the RFA, lasted 30 minutes twice weekly over 12 weeks. The primary outcomes measured were the Study of Osteoporotic Fractures index (serving as an indicator of frailty status) and the diagnostic criteria for sarcopenia (appendicular skeletal muscle mass index, handgrip strength, and gait speed). The secondary outcomes included functional performance (box and block test as well as maximum voluntary isometric contraction of the dominant upper extremity), muscle condition (muscle thickness measured using ultrasonography), activities of daily living (Kihon checklist), health-related quality of life (Short Form Health Survey-36), and cognitive function (brain health test). We used an intention-to-treat analysis, incorporating a simple imputation technique in statistical analysis. A mixed ANOVA, with time as a within-participant factor and intervention as a between-participant factor, was used to compare the training effects on outcomes., Results: We recruited 96 individuals, of whom 60 (62%) underwent randomization. Of these 60 participants, 55 (92%) completed the study. Significant group×time interactions were observed in the intervention group in all primary outcomes (all P<.001, except P=.01 for handgrip strength) and most secondary outcomes, including maximum voluntary isometric contraction of the biceps (P=.004) and triceps brachii (P<.001) muscles, biceps muscle thickness measured using ultrasonography (P<.001), box and block test (P<.001), Kihon checklist (physical function: P=.01, mood status: P=.003, and total: P=.003), and brain health test (P<.001)., Conclusions: The exergame-RFA intervention significantly improved muscle mass, strength, and functional performance among older adult users of rural LTCFs, offering a novel approach to addressing frailty and sarcopenia., Trial Registration: ClinicalTrials.gov NCT05360667; https://clinicaltrials.gov/study/NCT05360667., International Registered Report Identifier (irrid): RR2-10.3389/fmed.2022.1071409., (©Sheng-Hui Tuan, Lin-Hui Chang, Shu-Fen Sun, Chien-Hui Li, Guan-Bo Chen, Yi-Ju Tsai.

Background: Most existing studies measure atrial septal defect (ASD) outcomes based on morbidity rates such as atrial arrhythmias and heart failure rather than the functional assessment of physical capacity postprocedure. Few studies have evaluated cardiopulmonary function in ASD children. This study represents the largest sample population in the current research, encompassing a total of 122 Taiwanese children with ASD who had undergone treatment, to evaluate cardiopulmonary functional capacity through the implementation of cardiopulmonary exercise testing (CPET), and to investigate whether variations in treatment may impact their cardiopulmonary function., Methods: This is a retrospective cohort study with the data collected from January 2010 to December 2021. All patients and controls (age-, sex-, and body mass index-matched) underwent CPET and pulmonary function testing., Results: In total, 122 ASD patients (surgically closed ASDs 27, transcatheter-closed ASDs 48, and follow-up unrepaired ASD 47) and 244 healthy controls were recruited. The ASD group exhibited lower peak metabolic equivalent (MET), peak oxygen consumption (VO 2 , p < 0.001), and peak minute ventilation ( p = 0.028) along with MET and VO 2 at the anaerobic threshold (AT) ( p = 0.012) compared to the control group. No statistically significant differences were observed in the pulmonary function test. Among surgically closed, transcatheter closed and unrepaired ASD subgroups, no significant variances were seen in CPET and pulmonary function tests., Conclusion: Taiwanese ASD children exhibited diminished exercise capacity and cardiopulmonary performance compared to their healthy counterparts. Differences among specific ASD treatments in cardiopulmonary tests were non-significant., Competing Interests: Conflicts of interest: The authors declare that there are no conflicts of interest related to the subject matter or materials discussed in the article., (Copyright © 2024, the Chinese Medical Association.)

Objectives: Medical adverse event (MAE) reporting and management are essential for patient safety campaigns. An epidemiological assessment of MAE trends is crucial for understanding the effectiveness of patient safety improvement efforts. This study analyzed the trends of inpatient MAEs, focusing on MAE incidence and harm severity., Methods: Longitudinal secondary data (over 2014-2020) on MAEs reported by 18 hospitals were retrieved from the Taiwan Patient-safety Reporting system. The numbers and incidence rates (per 1000 inpatient days) of reported MAEs were calculated. The harm severity levels of six major MAE categories were analyzed. Trend and generalized estimating equation analyses were conducted to investigate changes in MAE patterns., Results: Trend analyses revealed significant decreasing trends in the number (4763-3107 per year; Jonckheere-Terpstra test = -1.952, P = 0.05) and incidence rates (0.92-0.62 per 1000 inpatient days; β = -0.5017, P = 0.00) of harmful MAEs over 7-year study period. Among the most frequently reported MAEs, tube-related events exhibited the most significant decreasing trend (28%-23.8%; Jonckheere-Terpstra test = -2.854, P = 0.00). The reported numbers, incidence rates, and severity of falls and tube-related events dropped significantly., Conclusions: By analyzing representative longitudinal MAE data, this study demonstrated the effectiveness of nationwide patient safety improvement campaigns in Taiwan. Our data reveal significant reductions in the reported numbers, incidence rates, and severity of several major MAEs. Specifically, our data indicate significant reductions in the incidence and severity of tube-related events, which can be beneficial for patient safety improvement efforts., Competing Interests: The authors disclose no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.
