Short-Form Video Exposure and Its Two-Sided Effect on the Physical Activity of Older Community Women in China: Secondary Data Analysis

Wu, Chen; Chen, Si; Wang, Shan; Peng, Sijing; Cao, Jiepin
BACKGROUND/UNASSIGNED:There is a tendency for older adults to become more physically inactive, especially older women. Physical inactivity has been exacerbated since the COVID-19 pandemic. Lockdowns and information-based preventive measures for COVID-19 increased the number of short-form video app users and short-form video exposure, including content exposure and the duration of exposure, which has demonstrated important effects on youths' health and health-related behaviors. Despite more older adults viewing short-form videos, less is known about the status of their short-form video exposure or the impacts of the exposure on their physical activity. OBJECTIVE/UNASSIGNED:This study aims to describe physical activity-related content exposure among older adults and to quantify its impacts along with the duration of short-form video exposure on step counts, low-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA). METHODS/UNASSIGNED:We analyzed a subsample (N=476) of older women who used smartphones and installed short-form video apps, using the baseline data collected from an ongoing cohort study named the Physical Activity and Health in Older Women Study (PAHIOWS) launched from March to June 2021 in Yantai, Shandong Province, China. The information on short-form video exposure was collected by unstructured questions; physical activity-related content exposure was finalized by professionals using the Q-methodology, and the duration of exposure was transformed into hours per day. Step counts, LPA, and MVPA were assessed with ActiGraph wGT3X-BT accelerometers. Multiple subjective and objective covariates were assessed. Linear regression models were used to test the effects of short-form video exposure on step counts, LPA, and MVPA. MVPA was dichotomized into less than 150 minutes per week and 150 minutes or more per week, and the binary logistic regression model was run to test the effects of short-form video exposure on the achievement of spending 150 minutes or more on MVPA. RESULTS/UNASSIGNED:Of 476 older women (mean age 64.63, SD 2.90 years), 23.7% (113/476) were exposed to physical activity-related short-form videos, and their daily exposure to short-form videos was 1.5 hours. Physical activity-related content exposure increased the minutes spent on MVPA by older women (B=4.14, 95% CI 0.13-8.15); the longer duration of short-form video exposure was associated with a reduced step count (B=-322.58, 95% CI -500.24 to -144.92) and minutes engaged in LPA (B=-6.95, 95% CI -12.19 to -1.71) and MVPA (B=-1.56, 95% CI -2.82 to -0.29). Neither content exposure nor the duration of exposure significantly increased or decreased the odds of older women engaging in MVPA for 150 minutes or more per week. CONCLUSIONS/UNASSIGNED:Short-form video exposure has both positive and negative impacts on the physical activity of older adults. Efforts are needed to develop strategies to leverage the benefits while avoiding the harms of short-form videos.

Ceftazidime-Avibactam Treatment for Severe Post-Neurosurgical Meningitis and Abscess Caused by Extended-Spectrum β-Lactamase Escherichia coli in a Pediatric Patient: A Case Report

Ren, Jing; Wang, Qinhui; Liu, Linna; Xiao, Yunfeng; Ji, Peigang; Du, Hui; Wang, Shan; Zheng, Yao; Yang, Qi
Post-neurosurgical infections caused by multidrug-resistant Enterobacterales are difficult to treat due to limited therapeutic options. Ceftazidime-avibactam (CAZ-AVI), a combination of cephalosporin and a novel β-lactamase inhibitor, has exhibited potential activity against multi/extensive drug-resistant (MDR/XDR) gram-negative bacilli. Several reports have described the successful treatment of central infections caused by MDR/XDR Pseudomonas aeruginosa or Enterobacterales. However, data on the efficacy and effective drug distribution of CAZ-AVI in the central nervous system (CNS), particularly in children, are lacking. We report a case of a 4-year-old girl with post-neurosurgical meningitis and abscess caused by extended-spectrum β-lactamase-producing Escherichia coli successfully treated with CAZ-AVI. CAZ-AVI therapeutic drug monitoring was performed to evaluate its efficacy and effective drug distribution in the CNS. We measured CAZ (15.6, 7.1, and 3.5 μg/mL) and AVI (4.0, 2.1, and 1.2 μg/mL) in cerebrospinal fluid (CSF) samples obtained 3, 5, and 7 h after the administration of the 15th CAZ-AVI dose (2.5 g, q8h, iv), respectively. We also measured CAZ (57.0 and 25.8 μg/mL) and AVI (11.3 and 4.5 μg/mL) in serum samples obtained 3 and 5 h after the administration, respectively. CAZ-AVI achieved an adequate CSF concentration throughout the drug interval. Our case provides evidence for using CAZ-AVI to treat CNS infections.

Institutional Usage of Ferric Pyrophosphate Citrate (FPC) Delivered Via Dialysate in Reducing Erythropoiesis Stimulating Agents (ESAs) and IV Iron Cost

Wang, Shan; DellaFera, Louis; Dhanani, Lameesa; Malone, Brian; Dutka, Paula; Akerman, Meredith; Masani, Naveed
Dialysis patients are often iron deficient due to a multiple factors. Ferric pyrophosphate citrate is a complex iron salt that can be given via dialysate allowing maintenance of hemoglobin (Hgb) concentration and iron balance while reducing the need for IV iron. The purpose of this study is to perform a cost evaluation of FPC and the effect it has on lowering the dose/use of ESAs and IV iron therapy. This study reviewed the same 100 hemodialysis patient's charts before and after the use of FPC. The data points that were collected and analyzed are as follows: hemoglobin, ferritin levels, average weekly ESA dosing, and IV iron replacement therapy dose. Out of 100 patients, there was no statistical difference in the average hemoglobin, ferritin, and iron saturation levels observed in the patients before and after FPC use. The average weekly dose of darbepoetin alfa per patient was 52.74 μg before the FPC group compared to 39.27 μg in the post FPC group (P < .0001). The total dose of ferric gluconate per patient was 3290.01 mg in the before FPC group and 585.60 mg in the post FPC group (P < .0001). The average total iron sucrose dose per patient in the before FPC group was 3097.92 mg versus 1216.67 mg in the post FPC group (P < .1563). When comparing FPC's cost and implementation into both of our outpatient dialysis centers, this yielded a net savings of $296 751.49.

Assessment of Safety of Remdesivir in Covid -19 Patients with Estimated Glomerular Filtration Rate (eGFR) < 30 ml/min per 1.73 m^2

Wang, Shan; Huynh, Christy; Islam, Shahidul; Malone, Brian; Masani, Naveed; Joseph, D'Andrea
PURPOSE/OBJECTIVE:Safety of remdesivir in patients with renal impairment is unknown. Incidence of liver injury secondary to remdesivir is also unknown. The objective of this study is to assess the incidence of acute kidney injury (AKI) and to trend the liver enzymes during remdesivir treatment and change in eGFR from baseline to end of treatment as well as 48 h post completion of remdesivir therapy. METHODS:This is a retrospective chart review study including adult patients admitted with COVID-19 receiving remdesivir with a baseline eGFR < 30 ml/min per 1.73 m^2 from December 2020 to May 2021. The primary outcome was to assess the incidence of AKI and hepatic injury. The secondary outcome was to assess the efficacy of remdesivir defined by change in oxygen requirement. RESULTS:Seventy-one patients were included in the study. Patients experienced an improvement in eGFR from baseline (T0) to end of remdesivir treatment (T1), as well as 48 h after the end of the treatment (T2) ( + 30.3% and + 30.6% respectively, P < .0001). Creatinine reduced from baseline (T0) to T1 and T2 (-20.9% and -20.5% respectively, P < .0001). Creatinine clearance improved from baseline to T1 and T2 ( + 26.6% and + 26.2% respectively, p < .0001). Elevation of aminotransferase (AST) was observed at T1 ( + 2.5%, P  =  .727), however, AST reduction was seen at T2 (-15.8%, P  =  .021). Elevation in alanine transaminase (ALT) was observed at T1 and T2 ( + 25% and + 12%, P  =  .004 and P  =  .137 respectively). Both direct and total bilirubin remained stable and were not significantly changed from baseline. CONCLUSION/CONCLUSIONS:Our study showed that remdesivir use in renally-impaired patients with eGFR < 30 ml/min is safe. Remdesivir may be considered as a therapeutic option in this population with COVID-19 infection.

Valproic Acid After Neurosurgery Induces Elevated Risk of Liver Injury: A Prospective Nested Case-Control Study

Guo, Jinlin; Ma, Jiuhong; Wang, Shan; Li, Xingang; Ji, Hongming; Li, Yuanping; Peng, Fangchen; Sun, Yiqi
BACKGROUND:Valproic acid (VPA) has been widely used to prevent epileptic seizures after neurosurgery in China. We have found that the incidence of liver injury (LI) in patients using VPA after neurosurgery is higher than that in other patients. OBJECTIVE:The objective of this study was to investigate the risk factors of LI in patients using VPA after neurosurgery. METHODS:A nested case-control study was conducted in patients using VPA after neurosurgery between September 2019 and March 2021. Cases of LI were matched to controls by age and body mass index (BMI). Conditional logistic regression was used to estimate matched odds ratios representing the odds of LI. A receiver operating characteristic curve was used to analyze the optimal cutoff condition. RESULTS:A total of 248 people (62 LI and 186 control) were enrolled. Among patients with vs without LI, the matched odds ratio for trough concentration of VPA was significant (matched odds ratio [OR], 1.09; 95% confidence interval [CI]: 1.01-1.19). The course of treatment (OR: 1.17, 95% CI: 1.02-1.33), Glasgow score (OR: 0.26, 95% CI: 0.10-0.67), gene polymorphisms of CYP2C19 (OR: 2.09, 95% CI: 1.03-146.93), and UGT1A6 (OR: 34.61, 95% CI: 1.19-1003.23) were all related to the outcome. The optimal cutoff of the course of treatment was 10 days, while the trough concentration of VPA was determined to be 66.16 mg/L. CONCLUSION/CONCLUSIONS:Length of treatment, VPA trough concentration, and Glasgow score were associated with LI in patients after neurosurgery. A gene test may be necessary for people who are prescribed VPA for a long time.
