Introduction: We evaluated the risk of shortness of inhalation when using laninamivir without inhalation practices.

Method: We counted the number of attempts required by each patient to sound the whistle. We classified the patients into the following categories: ①Sound rang in the first attempt; ②Sound rang within 3 attempts; ③Sound rang with in 5 attempts; ④Sound rang within 10 attempts; ⑤The whistle did not sound. We assessed the following: 1. the rate of patients younger than 10 years of age assessed category ② or less,; 2. the rate of patients of teen-age, and 3. the rate of patients of 20 years of age or older, assessed category ③ or less.

Results: We examined 56 patients, and we found that the rate for 1. was 7/11= 63.6%, for 2. was 4/33= 12.1%, and for 3. was 2/12= 16.7%.

Conclusion: We found that more than 60% of patients younger than 10 years of age and more than 10% of patients of 10 years of age or older were at risk of shortness of inhalation when using laninamivir without inhalation practices. And we propose other medication if patients cannot sound the whistle within about 5 attempts.

Background: Although previous reports have shown a lower proportion of the ACTN3 XX genotype (R577X nonsense polymorphism) in sprint/power athletes compared with controls, possibly attributed to the importance of skeletal muscle function associated with alpha-actinin-3 deficiency, the findings on association between endurance athlete status and R577X genotype are equivocal. Purpose: The present study was undertaken to examine association of ACTN3 R577X genotype with elite Japanese endurance athlete status. Subjects and Methods: Subjects comprised 79 elite Japanese endurance runners (E) who participated in competition at national level and 96 Japanese controls (C). We divided endurance runners into two groups, i.e., 42 national level runners (E-N) and 37 international level runners (E-I) who had represented Japan in international competition. R577X genotype (rs1815739) was analyzed by direct sequencing. Frequency differences of polymorphisms between athletes and controls were examined by Chi-square tests. Result: The R allele frequency tended to be higher in E group than in C group (P=0.066). When we divided E into two groups, the R allele frequency in E-I group was significantly higher than that in C group (P=0.046); whereas there were no significant differences between E-N and C groups (p=0.316). Then, the three genetic models were tested. In the additive genetic model (RR>RX>XX), there were significantly differences between E-I and C (P=0.038), but not the dominant (RR vs. RX+XX) and the recessive (RR+RX vs. XX) genetic models. Conclusion: R allele of the R577X genotype in the ACTN3 gene was associated with elite Japanese endurance athlete status.

　　This study investigated data on cardiopulmonary exercise testing (CPX) indices in order to estimate exercise intensity and ramp load from maximum walking speed (MWS) in elderly hospitalized patients with acute coronary syndrome (ACS). Subjects were 66 male patients hospitalized with ACS (49 young-old patients and 17 old-old patients). We measured exercise intensity by CPX using a cycle ergometer and MWS over 10 m, and examined the patients’ clinical characteristics. Stepwise multiple regression analysis was performed to identify variables that most closely predicted exercise intensity. We then estimated the ramp load from the relationship between exercise load at anaerobic threshold and MWS. The results indicated that MWS was an independent predictor of exercise intensity in old-old patients (adjusted R²=0.278, p=0.037) but not in young-old patients. The regression formula predicted the proper ramp load to be 5 and 10 watts as MWS was less than 1.5m/s or more than 1.5m/s, respectively. MWS was related to exercise intensity and could be used to consider the ramp load in CPX in old-old male patients with ACS.

Purpose: To compare the effects of aging in patients with acute myocardial infarction (AMI) on their clinical background and hospitalization progress, and to examine the relationships between age and these factors.
Subject: One hundred and fifty-three patients who experienced cardiac rehabilitation after percutaneous coronary intervention (PCI) (63.8±11.1 y.o, 126 men, 27 women).
Method: The patients were divided into the middle aged group (<65 y.o, n=84), young old group (65 to 74 y.o, n=44), and old group (75 y.o≥ n=25). The differences between groups were examined in respect of 13 items about clinical backgrounds (responsibility coronary arteries, CKmax, LVEF, residual stenosis, hypertension, diabetes, hyperlipemia, smoking, and BMI) and hospitalization progress (cardiac complications, locomotorium disabilities, abnormality as 200mECG, and duration of hospitalization).
Results: Left veticular ejection fraction (LVEF) was significantly lower in the old group than in the young old group. The old group had a high rate of residual stenosis. In the coronary risk factors, all of the groups had hypertension at a high rate of 54.5% or over. The middle aged group and young old group had diabetes at about 38%. The middle aged group was prone to hyperlipemia, and had significantly a high smoking rate. Body mass index (BMI) was significantly higher in the middle aged group than in the old group. In hospitalization progress, the old group had a high rate of cardiac complications and locomotorium disability. The duration of hospitalization was significantly longer in the old group than in the other groups.
Conclusion: It would be necessary to give middle-aged persons educational guidance for the improvement of the coronary risk factors, and to provide the old persons with the suitable rehabilitation programs considering various complications.

Purpose: This study was performed to compare the characteristics of home palliative care for elderly patients with cancer between age groups. Methods: The clinical records of 1,032 patients with cancer who received home medical care from June to November 2013 were reviewed retrospectively. Patients were classified as non-elderly (<65 years old), young-old (65-74 years), old-old (75-84 years), or oldest-old (≥85 years), and these groups were compared with respect to demographic characteristics, patient/family problems, outcomes, and medical care and services provided. Results: There was a higher percentage of patients with no caregiver in the oldest-old group than in the other groups (18%, p=0.014), while the young-old and oldest-old groups had a higher percentage of problems related to caregiving such as caregiver burden or absence of a caregiver (32% and 33%, p=0.002, respectively). In addition, the percentage of patients who required visiting nurses and care was higher in the old-old group (86% and 30%, respectively) and oldest-old group (89% and 35%, respectively) compared with the other two groups. Conclusion: Problems related to caregiving, such as caregiver burden or absence of a caregiver, were greater in the old-old and oldest-old groups, and a higher percentage of patients required visiting nurses and care in those two groups.

Objective: This study investigated the association between use of sedatives in terminal cancer patients near death who were receiving home care and the home care period. Methods: We conducted a retrospective review of the medical records for 1032 cancer patients who received home palliative care from 17 specialized home care clinics between June and November 2013. We checked the use of sedatives within 48 hours before death at home, and we compared the home care period between patients with and without sedation. Results: The sedatives used were diazepam (n, %: 100, 52%), flunitrazepam (29, 15%), bromazepam (27, 14%), midazolam (26, 13%), and phenobarbital (20, 10%). The median home care period (median [quartiles]) was 26 [13, 63] days and 25 [10, 64] days (Adj p=0.79) for the patients with and without sedatives, respectively. Conclusion: Among terminal cancer patients near death receiving home care, 24% were administered sedatives, with more than half of those patients receiving diazepam. There was no association between use of sedatives and the home care period.
