Purpose:
Exercise is an effective non-pharmacological approach for alleviating treatment-related adverse effects and enhancing physical fitness in breast cancer survivors. A Kinect-based mixed reality device (KMR), with real-time feedback and user data collection, is an innovative exercise intervention for breast cancer survivors. This study aimed to investigate the effect of KMR exercise program on quality of life (QOL) and physical function in breast cancer survivors.
Materials and Methods:
Seventy-seven participants were randomly assigned to either the KMR exercise group or home stretching group with an 8-week intervention. Physical function (shoulder range of motion, body composition, aerobic capacity, and hand grip strength) was evaluated before and after the intervention period. Participants completed questionnaires such as the Disabilities of the Arm, Shoulder, and Hand (DASH), Functional Assessment of Cancer Therapy-Breast, and International Physical Activity Questionnaire (IPAQ) to assess upper extremity disabilities, QOL, and physical activity levels.
Results:
Significant group-by-time interaction was found for flexion of the operated arm (154.3±12.5 to 165.8±11.2), and the non-operated arm (158.2±13.8 to 166.5±12.2), abduction of the non-operated arm (154.8±31.6 to 161.1±28.1), and adduction of the operated arm (46.5±9.1 to 52.6±7.2). Significant improvements were also observed in DASH (46.8±9.1 to 40.8±9.3) and IPAQ (1,136.3±612.8 to 1,287±664.1).
Conclusion
The KMR exercise program effectively improved the physical function, alleviated edema, reduced upper extremity disability, and enhanced the QOL in breast cancer survivors. Coupled with significant group-by-time interactions for various outcomes, the results emphasize the potential benefits of incorporating the KMR exercise program to improve the QOL in breast cancer survivors.

Background:
Sarcopenia is a muscle-wasting condition that affects older individuals. It can lead to changes in movement patterns, which can increase the risk of falls and other injuries.
Methods:
Older women participants aged ≥65 years who could walk independently were recruited and classified into two groups based on knee extension strength (KES). Participants with low KES scores were assigned to the possible sarcopenia group (PSG; n=7) and an 8-week exercise intervention was implemented. Healthy seniors with high KES scores were classified as the reference group (RG; n=4), and a 3-week exercise intervention was conducted. Kinematic movement data were recorded during the intervention period. All participants' exercise repetitions were used in the data analysis (number of data points=1,128).
Results:
The PSG showed significantly larger movement patterns in knee rotation during wide squats compared to the RG, attributed to weakened lower limb strength. The voting classifier, trained on the movement patterns from wide squats, determined that significant differences in overall movement patterns between the two groups persisted until the end of the exercise intervention. However, after the exercise intervention, significant improvements in lower limb strength in the PSG resulted in reduced knee rotation range of motion and max, thereby stabilizing movements and eliminating significant differences with the RG.
Conclusion
This study suggests that exercise interventions can modify the movement patterns in older individuals with possible sarcopenia. These findings provide fundamental data for developing an exercise management system that remotely tracks and monitors the movement patterns of older adults during exercise activities.

Vitamin C is a well-known antioxidant with antiviral, anticancer, and anti-inflammatory properties based on its antioxidative function. Aptamin C, a complex of vitamin C with its specific aptamer, has been reported to maintain or even enhance the efficacy of vitamin C while increasing its stability. To investigate in vivo distribution of Aptamin C, Gulo knockout mice, which, like humans, cannot biosynthesize vitamin C, were administered Aptamin C orally for 2 and 4 weeks.The results showed higher vitamin C accumulation in all tissues when administered Aptamin C, especially in the spleen. Next, the activity of natural killer (NK) cells were conducted. CD69, a marker known for activating for NK cells, which had decreased due to vitamin C deficiency, did not recover with vitamin C treatment but showed an increasing with Aptamin C. Furthermore, the expression of CD107a, a cell surface marker that increases during the killing process of target cells, also did not recover with vitamin C but increased with Aptamin C. Based on these results, when cultured with tumor cells to measure the extent of tumor cell death, an increase in tumor cell death was observed. To investigate the signaling mechanisms and related molecules involved in the proliferation and activation of NK cells by Aptamin C showed that Aptamin C treatment led to an increase in intracellular STAT3 activation. In conclusion, Aptamin C has a higher capability to activate NK cells and induce tumor cell death compared to vitamin C and it is mediated through the activation of STAT3.

Fexuprazan (DWP14012), a potassium-competitive acid blocker, is a medical formulation prescribed to inhibit the secretion of gastric acid. The present study encompasses a comparative evaluation of pharmacokinetic (PK) analysis between the previous (reference) and size-reduced (test) formulation of fexuprazan 20 mg in healthy subjects. The study employed a randomized, open-label, single-dose, 2-sequence, 2-period, crossover design with a 7-day wash-out between periods. A total of 24 subjects were enrolled in this randomized study. During each period, the 21 subjects received either the test or reference formulation. Blood samples were collected at multiple time point ranging from 0 (pre-dose) to 48 hours post-dosing for PK analysis. The calculated PK parameters were considered bioequivalent when the 90% confidence intervals (CIs) of the geometric mean ratios (GMRs) were within the bioequivalence limit of 0.8–1.25. Safety and tolerability were included in the evaluation. A total of 20 subjects completed the study. Point estimates (90% CIs) of the GMRs were 1.1014 (0.9892–1.2265) for the maximum plasma concentration and 1.0530 (0.9611–1.1536) for the area under the plasma concentration-time curve from zero to the time of the last quantifiable concentration, between the test and reference formulations.The reference and size-reduced test formulations of fexuprazan were well tolerated with no reports of serious adverse events. In conclusion, size-reduced and previous formulations of fexuprazan 20 mg were bioequivalent with regard to PKs, safety and tolerability.

Purpose:
This descriptive study aimed to identify the incidence and related factors of reintubation after unplanned extubation in the neonatal intensive care unit.
Methods:
A secondary data analysis was conducted using electronic medical records. All events of unplanned extubation were audited from January 2020 to August 2021. The data were analyzed by chi-square test using IBM SPSS Statistics ver. 24.0 program.
Results:
Fifty-eight unplanned extubation events were identified for 20 months. The incidence was 2.6 per 100 ventilation days during the study period. After unplanned extubation, 35 neonates (60.3%) were immediately reintubated. There was a statistically significant difference between the gestational age (p=0.018) and postconceptional age at unplanned extubation (p=0.044) and the total intubation period (p=0.003) between the reintubation and nonreintubation groups.
Conclusion
These findings indicate that the incidence of unplanned extubation was significantly higher than that of an adult in South Korea. According to this study, targeting interventions are required to prevent unplanned extubation and ensure patient safety.

Purpose:
Exposure to particulate matter (PM) is a well-known risk factor in the triggering and exacerbation of allergic airway disease. Indoor environments, where people spend most of their time, are of utmost importance. To assess the effects of air purifiers [equipped with high-efficiency particulate air (HEPA) filters] on allergic rhinitis (AR) in adult patients, we performed a multicenter, randomized, double-blind, and placebo-controlled study.
Materials and Methods:
Patients with house dust mite (HDM)-induced AR were randomly assigned to either active or mockup (placebo) air-purification groups. Two air purifiers (placed in living room and bedroom) were operated for 6 weeks in each home environment. The primary study endpoint was to achieve improvement in AR symptoms and medication scores. Secondary endpoints were to achieve improvement in the quality of life (QoL) and visual analog scale (VAS) scores, as well as in the indoor (bedroom and living room) concentrations of PM2.5 and PM10.
Results:
After 6 weeks of air purifier use, medication scores improved significantly in the active (vs. placebo) group, although subjective measures (symptoms, VAS, and QoL scores) did not differ. Bedroom PM2.5 concentrations initially exceeded living room or outdoor levels, but declined (by up to 51.8%) following active purifier operation. Concentrations of PM2.5 in living room and PM10 in bedroom and living room were also significantly reduced through active purification.
Conclusion
The use of air purifiers with HEPA filters significantly reduced medication requirements for patients with HDM-induced AR and significantly lowered indoor PM2.5 concentrations, regardless of room placement. Active intervention to reduce household air pollutants may help improve allergic airway disease (clinicaltrials.gov NCT03313453).
