Using exergame-based exercise to prevent and postpone the loss of muscle mass, muscle strength, cognition, and functional performance among elders in rural long-term care facilities: A protocol for a randomized controlled trial
ObjectiveElderly individuals in long-term care facilities (LTCFs) have a higher prevalence of sarcopenia than those in the community. Exercise is the gold standard for preventing and treating sarcopenia. Regarding exercise, multicomponent exercises, including progressive resistance training (PRT), are beneficial. However, developing routine, structured exercise programs for the elderly in LTCFs is difficult because of a shortage of healthcare providers, particularly in rural regions. Exergame-based exercises can increase a player’s motivation and reduce staff time for an intervention. Nintendo Switch RingFit Adventure (RFA) is a novel exergame that combines resistance, aerobic, and balance exercises. In this study, we aim to investigate the clinical effectiveness of RFA on muscle and functional performance parameters among the elderly in LTCFs.MethodsThe EXPPLORE (using EXergame to Prevent and Postpone the LOss of muscle mass, muscle strength, and functional performance in Rural Elders) trial is a single-center randomized controlled trial involving elderly individuals (≥60 years) living in LTCFs in rural southern Taiwan. The participants will be equally randomized to the intervention group (exergame-based exercise plus standard care) or the control group (standard care alone). Both groups will receive standard care except that the intervention group will receive exergame-based exercises at the time previously scheduled for sedentary activities in the LTCFs. The exergame-based exercise will be performed using RFA in the sitting position with a specialized design, including arm fit skills and knee assist mode. Each session of the exercise lasts 30 mins and will be performed two times per week for 12 weeks. The primary outcomes will be the osteoporotic fracture index, appendicular skeletal muscle mass index, dominant handgrip strength, and gait speed. Meanwhile, the secondary outcomes will be the dexterity and agility, muscle strength and thickness, range of motion of the joints of the dominant upper extremity, Kihon checklist, Medical Outcomes Study 36-Item Short-Form Health Survey, and Brain Health Test.DiscussionThis trial will provide valuable knowledge on whether exergames using RFA can counteract physical decline and improve quality of life and cognition among the elderly in LTCFs.Clinical trial registration[www.ClinicalTrials.gov], identifier [NCT05360667]
Cordycepin reverses cisplatin resistance in human bladder cancer cells via the PTEN/PI3K/AKt pathway
Purpose: To study the influence of cordycepin (Cor) on cisplatin insensitivity in bladder carcinoma, and its underlying mechanism of action.Methods: The effects of cisplatin and Cor treatments on the viability of T24-sensitive and T24/DDPinsensitive bladder carcinoma cells were investigated by using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method to assess selectivity index. Flow cytometry was employed to evaluate the apoptosis of T24/DDP-resistant bladder cancer cells treated with cisplatin and Cor. The concentrations of PTEN, p-AKt and Akt in T24/DDP-resistant bladder cancer cells treated with cisplatin and Cor were determined by western blot assay.Results: Compared with T24-sensitive cells, the sensitivity of T24/DDP-resistant bladder cancer cells to cisplatin was significantly decreased, along with significant increase in half-inhibitory concentration (IC50) value, resulting in 10.56-fold increase in resistance (p < 0.05). The median effective concentration (EC50) value of Cor for DDP reversal was 1.03 ± 0.15 μM, and it had a high selectivity index for normal cells (> 48.5). The results from flow cytometry showed that Cor significantly enhanced the apoptosisinducing capacity of DDP in T24/DDP-resistant cells (p < 0.05), while Western blot data indicate that PTEN protein expression increased and phosphorylated Akt protein expression decreased in T24/DDPresistantcells after Cor treatment when compared with control group (p < 0.05).Conclusion: Cordycepin significantly improves the sensitivity of T24/ DDP-resistant bladder cancer cells to cisplatin via a mechanism related to the activation of PTEN/AKt signaling pathway, thus indicating that it is a potential candidate reversing DDP-resistance in bladder cancer.

Laparoscopic resection for gastric GISTs: surgical and long-term outcomes of 133 cases
Background
It aims to evaluate the surgical efficacy and long-term survival of different laparoscopic surgeries for gastric GISTs.
Methods
From a prospectively collected database, 133 patients with primary gastric GISTs undergoing laparoscopic surgery were selected from January 2008 to December 2014. They were divided into three groups according to the different operations that were performed, including laparoscopic gastric wedge resection (LWR Group, n=103), laparoscopic subtotal gastrectomy (LSG Group, n=18) and laparoscopic total gastrectomy (LTG group, n=12). Clinicopathological features and short- and long-term outcomes were analyzed retrospectively.
Results
All patients had received R0 resection. There were no differences among the three groups in age, BMI or NIH risk classification. Compared with the LSG group and LTG group, the LWR group had a shorter operative time, less blood loss, fewer operative complications and shorter time to ground activities, semi-liquid diet and hospital stay (P<0.05). There was no statistically significant difference in time to first flatus and liquid diet or in the rate of postoperative complications (P<0.05). In the patients with a large tumor (size≥5 cm), LWR was significantly associated with shorter operative time, less blood loss and shorter hospital stay compared with the laparoscopic gastric non-wedge resection (N-LWR) (P<0.05). The median follow-up was 30 months, with 4 cases of recurrence and 3 deaths. The 5-year cumulative survival rate was similar among the three groups (P>0.05).
Conclusions
Compared with LSG and LTG, more favorable minimally invasive results can be achieved from LWR for gastric GISTs, which may be the optimal surgical procedure
Long-term proton pump inhibitor use and the incidence of gastric cancer: A systematic review and meta-analysis
Background: There are controverted whether the long-term use of proton pump inhibitors (PPI) will increase the risk of gastric cancer. We performed a meta-analysis to assess the risk of gastric cancer in PPI users compared with non-PPI users.
Methods: The main inclusion criteria were original studies reporting the incidence of gastric cancer in PPI users compared with non-PPI users. Key outcomes were the risk ratios (RR) for gastric cancer in association with PPI users or non-PPI users.
Results: We analyzed data from 8 studies, comprising more than 927,684 patients. The risk of gastric cancer in PPI users was significantly higher than in non-PPI users [RR= 2.10, 95% CI (1.17-3.97)]. The risk of gastric cancer was similar between the 2 groups when the duration was ≤1 year [RR= 2.18, 95% CI (0.66-7.11)]. While the risk of gastric cancer for PPI users was higher than in non-PPI users when the duration was between 1-3 years, ≥1 year, ≥3 years and ≥5 years. The risk of non-cardiac gastric cancer for PPI users was higher than for non-PPI users [RR= 2.66, 95% CI (1.66 -4.27)], and the risk of non-cardiac gastric cancer for PPI users was higher than for non-PPI users when the duration ≥1 year [RR= 1.99, 95% CI (1.03-3.83)], but the risk for cardiac gastric cancer was similar between the 2 groups [RR= 1.86, 95% CI (0.71-4.89)].
Conclusions: We found the long-term use of PPI (duration ≥1 year) was significantly associated with a higher risk of non-cardiac gastric cancer
