With increasing global life expectancy, the significance of geriatric assessment parameters has increased. Sarcopenia is a crucial assessment parameter and is defined as the age-related loss of muscle mass and strength. Sarcopenia is widely acknowledged as a risk factor for postoperative complications in diverse advanced malignancies and has a detrimental effect on the long-term prognosis. While most studies have primarily concentrated on the correlation between sarcopenia and advanced cancer, more recent investigations have focused on the relationship between sarcopenia and early-stage cancer. Endoscopic submucosal dissection (ESD), which is less invasive than surgical intervention, is extensively employed in the management of early-stage cancer, although it is associated with complications such as bleeding and perforation. In recent years, several reports have revealed the adverse consequences of sarcopenia in patients with early-stage cancer undergoing ESD. This literature review briefly summarizes the recent studies on the association between sarcopenia and ESD.

Objectives: “Adverse Drug Reaction Relief System” (hereinafter called the Relief System) has been established to provide prompt relief to patients experiencing health damage caused by adverse drug reactions. Since 2018, the Relief System has required community pharmacies that acquire additional points as local support system to actively report adverse drug reactions. Here, we investigated the recognition and utilization of the relief system among community pharmacists.Method: A questionnaire survey was conducted among community pharmacists between August 1 and September 30, 2019.Results: The survey achieved a response rate of 58.1%. The recognition rates of the relief system and Pharmaceuticals and Medical Devices Agency (PMDA) as its application destination were 98.9 and 74.5%, respectively. Of the community pharmacists, 2.6% had experience in utilizing the relief system; and 8.8% did not want to recommend the utilization of the relief system for patients mainly because of the “low recognition of the system” and “the complicated and troublesome preparation of the necessary documents such as medical certificates.” The community pharmacists who acquire additional points as local support system, compared with those who do not, achieved significantly higher rates in two items, including that for preparation of the documented procedures pertaining to adverse drug reactions.Conclusion: Despite the high recognition of the relief system among community pharmacists, the percentage of pharmacists with experience in actually utilizing the relief system and applying to the PMDA was low. One reason that the use of the relief system was not widespread was the low recognition particularly of the destination and procedures of reports on adverse drug reactions. In the future, educational campaigns to improve pharmacists’ comprehension of the relief system will be needed. Moreover, pharmacists must play a central role in enhancing the recognition of the public relief system and promoting medical safety.

Background:
Hybrid closed-wedge high tibial osteotomy (hybrid CWHTO) is an effective surgical treatment for medial compartment osteoarthritis of the knee. Our study investigated whether the combination of a lateral locking plate and a single medial screw promoted bone union after hybrid CWHTO.
Methods:
The study cohort consisted of 30 patients (15 men and 15 women) who underwent hybrid CWHTO for medial compartment osteoarthritis or spontaneous osteonecrosis of the knee. Sixteen knees were fixed with a lateral locking plate (LP group), and 17 were fixed with both a lateral locking plate and a cannulated cancellous screw on the medial side of the tibia (LPS group). The times to bone union, radiolucency, and callus formation at the osteotomy site were evaluated radiographically.
Results:
The mean postoperative time to radiographic confirmation of bone union was 5.5 ± 2.6 months in the LP group and 3.4 ± 1.5 months in the LPS group. Radiolucency at the osteotomy site and excess callus formation on the posterior side of the tibia were lower in the LPS group than in the LP group.
Conclusions
This modified hybrid CWHTO combining a lateral locking plate and a cannulated cancellous screw on the medial side of the tibia improves the stability of the osteotomy site and shortens the period of bone union.

PURPOSE: Endoscopic diagnosis of gastric cancer (GC) that emerges after eradication of Helicobacter pylori may be affected by unique morphological changes. Using comprehensive endoscopic imaging, which can reveal biological alterations in gastric mucosa after eradication, previous studies demonstrated that Congo red chromoendoscopy (CRE) might clearly show an acid non-secretory area (ANA) with malignant potential, while autofluorescence imaging (AFI) without drug injection or dyeing may achieve early detection or prediction of GC. We aimed to determine whether AFI might be an alternative to CRE for identification of high-risk areas of gastric carcinogenesis after eradication. MATERIALS AND METHODS: We included 27 sequential patients with metachronous GC detected during endoscopic surveillance for a mean of 82.8 months after curative endoscopic resection for primary GC and eradication. After their H. pylori infection status was evaluated by clinical interviews and ¹³C-urea breath tests, the consistency in the extension of corpus atrophy (e.g., open-type or closed-type atrophy) between AFI and CRE was investigated as a primary endpoint. RESULTS: Inconsistencies in atrophic extension between AFI and CRE were observed in 6 of 27 patients, although CRE revealed all GC cases in the ANA. Interobserver and intraobserver agreements in the evaluation of atrophic extension by AFI were significantly less than those for CRE. CONCLUSIONS: We demonstrated that AFI findings might be less reliable for the evaluation of gastric mucosa with malignant potential after eradication than CRE findings. Therefore, special attention should be paid when we clinically evaluate AFI findings of background gastric mucosa after eradication (University Hospital Medical Information Network Center registration number: UMIN000020849).

Objective: Collection of the latest information for appropriate and safe drug use is clinically essential, and the “Japan Pharmaceutical Association Drug Information” (JPADI) is a useful source. We prepared a text on the basis of JPADI for undergraduates to learn adverse drug events (ADEs). The objective of this study was to report the outcomes of our educational plan and student perspectives regarding the management of ADEs.
Methods: We provided 20 students with a self-study text for ADEs, including ADE reports, relief services by the Pharmaceuticals and Medical Devices Agency, and pharmacist medication errors. Case reports were categorized by disease discipline. Students were administered a questionnaire regarding their evaluation and interest regions of our text, the significance of relief services, and roles of drug information specialist.
Results: Fifteen students (75%) completed the questionnaire. Interest regions were pharmacist medication errors (n=9), systemic and multi-organ disorders (n=9), and cardiovascular disorders (n=5). We received comments such as “these errors are experiences creating cascades for the prevention of recurrence” (n=2). In terms of relief services, “expenses relief ” (n=4) as a merit and “vagueness of relief standards” (n=4) as a demerit were provided. Roles of drug information specialist included “provide easy-to-understand drug information to patients” (n=4) and “share with other medical staff ” (n=2). No specific improvements for the text were suggested.
Conclusion: Our educational plan using a self-study text based on drug information is useful for developing student responsibility and expertise for becoming pharmacist.

OBJECTIVETo examine the effectiveness of a drug abuse prevention program focusing on social influences for drug education classes in high school.
METHODSThe social influence program in the experimental group used role-playing led by a pharmacist, a police officer and a teacher. The intervention evaluation used a quasi-experimental design. The subjects were first-year students from 10 high schools assigned to the experimental group (6 schools, 828 students) and the control group (4 schools, 408 students). In the control group, a pharmacist used a conventional information program in a lecture format.
RESULTSRegarding knowledge about drug abuse, in both the experimental and control groups, and for both males and females, a long-term effect was observed immediately after the program and lasted up to 15 months. For three other measures, attitudes toward drug abuse problem, self-efficacy regarding drug abuse prevention, and perception of social support for preventing drug abuse, a short-term effect was generally observed in the experimental group beginning immediately after the program and lasting for 3 months. A long-term effect was evident in high-risk students with positive opinions regarding drugs. In the control group and for both males and females, although an effect was generally evident immediately after the program, neither a short-nor a long-term effect was observed in males, suggesting the difficulty in achieving lasting effects.
CONCLUSIONSThe social influence program in the experimental group showed remarkable effectiveness. Thus, the program may be useful for preventing drug abuse among high school students in Japan.

To promote habitual participation in physical activity, a 3-month program for lifestyle physical activity intervention (L group) and structured exercise intervention (E group) was carried out in a community in Okayama Prefecture. One year later, we compared the two intervention groups in terms of cost-effectiveness and behavioral change in habitual physical activity. A total of 250 subjects voluntarily participated in the lifestyle physical activity intervention ; and a total of 42 subjects participated in the structured exercise intervention. The number of participants decreased to 115 (46%) and 21 (50%), respectively, one year later. However, the proportion of subjects who practice endurance exercise increased significantly in both L and E groups ; and an additional 35 subjects (30%) started to practice endurance exercise in L group and 5 (24%) in E group after the interventions. The cost-effectiveness for a person newly starting the endurance exercise practice in the L group intervention was 29,206 yen ; and the E group intervention was 124,731 yen, a ratio of 1/4.3. The study suggests that the cost-effectiveness for the lifestyle physical activity intervention was 4 times better than the structured exercise intervention.
