Aim: The Japan Diabetes Society and The Japan Geriatric Society made a joint committee and published a new glycemic target in May 2016. Because reports on the state of glycemic control in elderly diabetic patients are insufficient, we investigated the state of glycemic control in this population before the new glycemic target was established.

Methods: We enrolled patients older than 65 years of age who had been prescribed antidiabetic drugs and hospitalized in the geriatric department of Nagoya University Hospital from April 1, 2015, to March 31, 2016. We investigated the participants' HbA1c, prescription of antidiabetic drugs carrying risks of severe hypoglycemia (risk drugs) at hospitalization, cognitive function, basic activities of daily living, and instrumental activities of daily living.

Results: A total of 63 patients were enrolled. Thirty-five patients were male, the mean age was 83.1±5.9 years old, and the average HbA1c was 7.6%±1.5%. The numbers of patients assigned to categories I, II, and III were 10, 12, and 41, respectively. For prescription of risk drugs, 6 participants were assigned to category I, 8 to category II, and 22 to category III. Prescription of risk drugs was associated with the HbA1c. Approximately one third of the patients using risk drugs had a lower HbA1c than the target value.

Conclusions: Risk drugs was not significantly associated with the established categories or age. Many of the patients who were prescribed risk drugs had a lower HbA1c than the target values.

Aim: To comparatively investigate whether dynapenia and sarcopenia, as defined by the Asian Working Group for Sarcopenia (AWGS), are associated with fear of falling in elderly patients with diabetes.

Methods: The subjects were outpatients with diabetes who were at least 65 years of age when they visited our hospital. Sarcopenia was evaluated based on the AWGS definition. The cutoff values for the appendicular skeletal mass index (multi-frequency bioelectrical impedance method), grip strength, and walking speed were, respectively, 7.0 kg/m² for men and 5.7 kg/m² for women, 26 kg for men and 18 kg for women, and ≤0.8 m/s for both men and women. Those with grip strength of less than or equal to the cutoff value were considered to have dynapenia. Fear of falling was assessed by a self-administered questionnaire survey with the Fall Efficacy Scale (FES) Japanese version. A multiple regression analysis was conducted using the FES score as a dependent variable and dynapenia or sarcopenia and moderators as explanatory variables.

Results: A total of 202 patients (male, n=127; female, n=75) were analyzed in this study. The FES scores of the patients with and without sarcopenia did not differ to a statistically significant extent in either male or female patients. The multiple regression analysis revealed a statistically significant association between dynapenia and the FES score in men (P=0.028).

Conclusions: In elderly outpatients with diabetes, no association was found between sarcopenia and the fear of falling in either men or women. In contrast, a statistically significant association was found between dynapenia and fear of falling in men. This suggests the importance paying attention to the fear of falling when examining elderly male diabetes patients with dynapenia.

Aim: The present study examined the effects of individual pain coping-skills training (PCST) on knee pain, pain coping strategies, physical functions, and daily physical activity among older outpatients with osteoarthritis.

Methods: Twenty-five older adults who suffered from knee pain and had been diagnosed to have knee osteoarthritis (men: n=4; 75.4±6.3 years) were assigned to either a PCST group (n=13) or a general health education group (n=12) according to their wishes. Both groups attended 20-minutes sessions once a week for 8 weeks. At the baseline, the basic attributes (e.g. gender, age, duration of knee pain, and medical history), BMI, and the severity of knee osteoarthritis were obtained. Additionally, knee pain and limitations in mobility, pain coping strategies, pain self-efficacy, exercise self-efficacy, lower muscle strength, mobility, accelerometer -based time spent in physical activity and sedentary behavior were assessed before and after the 8-week intervention period. Analyses were performed using an intention-to-treat principle. Differences in each variable between the groups were examined using an analysis of covariance. Each participant's baseline value was used as the covariate.

Results: Even after controlling for the baseline attributes and values, only the PCST group exhibited a significant improvement in pain self-efficacy (p=0.005), exercise self-efficacy (p=0.042), lower muscle strength (p=0.004) and mobility (p=0.027). Furthermore, the PCST showed a significant increase in moderate-to vigorous-intensity physical activity (p=0.052) and a decrease in medical behaviors as one of pain coping strategies (p=0.073).

Conclusion: The present study showed that PCST therefore appears to be a feasible and effective therapeutic strategy which improves self-efficacy for controlling knee pain, which may also result in increasing the self-efficacy for exercise, physical functions, and daily physical activities.

An 82 year-old male was referred to us because of a nodule in the upper lobe of his right lung, which was incidentally found by computed tomography (CT) carried out in the course of treating pneumonia. The nodule was identified as non-keratinizing squamous cell carcinoma of the lung by bronchoscopy. A close investigation revealed the tumor to be cT1bN3M1b, clinical Stage IV. Although we only adopted a wait-and-see approach because of his age and his suspected myelodysplastic syndrome, the nodule had regressed on CT images after a year. Fluorodeoxyglucose-positron emission tomography showed apparently decreased uptakes in the lymph nodes and adrenal gland. We considered this to be a systemic observation of spontaneous regression of carcinoma.

A 71-year-old woman with a 9-year history of Parkinson's disease was admitted to our hospital emergently because of consciousness disturbance. Her consciousness level was 200 on the Japan coma scale (JCS), and she presented with tenderness and distension of the lower abdomen. Brain computed tomography showed normal findings. Blood tests showed an increased ammonia level (209 μg/dl) with normal AST and ALT levels. We catheterized the bladder for urinary retention. Five hours after admission, the blood ammonia level decreased to 38 μg/dl, and her consciousness level improved dramatically. Corynebacterium urearyticum, a bacterial species that produces urease, was detected by urine culture. Therefore, she was diagnosed with hyperammonemic encephalopathy resulting from urinary tract infection caused by urease-producing bacteria. In this case, urologic active agents had been administered to treat neurogenic bladder. We suspect that these drugs caused urinary obstruction and urinary tract infection. It is important to recognize that obstructive urinary tract infection caused by urease-producing bacteria can cause hyperammonemia. Neurological disorders, such as Parkinson's disease, tend to complicate neurogenic bladder. This disease should be considered in elderly patients with Parkinson's disease who are receiving urologic active drugs.

A 70-year-old woman was diagnosed with chronic rheumatoid arthritis and treated with methotrexate and prednisolone. She visited our hospital to determine the cause of her continuous fatigue and fever for the past three weeks. She consumed no food orally and was provided antibiotics because free air was found on computed tomography (CT). Intraperitoneal small lymphadenopathy and swelling of both adrenal glands was also found on CT, and MTX-associated lymphoproliferative disorder (MTX-LPD) was suspected. Am adrenal gland biopsy showed diffuse large B-cell lymphoma (DLBCL) associated with MTX-LPD. The causes of gastrointestinal perforation with collagen diseases have been reported to be functional gastrointestinal disorders with collagen diseases like amyloidosis, gastrointestinal infections in immunocompromised patients, and side effects of medication, such as steroids or NSAIDs and MTX. MTX-LPD is an uncommon side effect of methotrexate. To ensure its appropriate diagnosis and treatment, it is important to improve the degree of recognition of MTX-LPD, and a prompt response is needed.

Enteral nutrition is often performed in elderly patients with dysphagia. Choledocholithiasis is a disease that is common in elderly patients. Gastrointestinal hemorrhaging can occur in association with endoscopic sphincterotomy, and subsequent enteral nutrition must be carefully resumed. We herein report our experience using Mermed Plus containing sodium alginate after endoscopic hemostasis. The patient was an 88-year-old woman with an onset of gallstone cholangitis during rehabilitation after cerebral infarction. On day 2, endoscopic sphincterotomy and biliary drainage were performed, and the cholangitis was ameliorated. The degree of arousal and swallowing function were unstable, and a liquid diet via the nasogastric tube was initiated from day 6. Anemia progressed on day 7, and melena was observed; as a result, the intravenous administration of a proton pump inhibitor was initiated. On day 8, endoscopic hemostasis of the ulcer proximal to the papilla was performed. From day 10, we focused on the mucosal protective effects of sodium alginate, and Mermed Plus was initiated. No recurrence of hemorrhaging was observed. On day 13, the endoscopic findings revealed that the vicinity of the papilla was covered with solidified liquid diet, and the ulcer had healed. The postoperative course was uneventful, and swallowing training and rehabilitation were performed. On day 26, oral ingestion became possible. Many patients seem to be at risk of developing a gastrointestinal mucosal disorder when receiving enteral nutrition. In such cases, a liquid diet containing sodium alginate as dietary fiber is easy to use and may be useful for resuming enteral nutrition without delay.
