High-resolution boundary layer radar (BLR) and wavelet are utilized to observe microscale downdraft-updraft combinations. High-resolution BLR can observe thermal activity that pushed the stable layer. During this thermal, a combination of downdraft-updraft was also observed. A detailed observation of this combination was conducted in this study. Using a 1-dimensional continuous wavelet transform with Paul wavelet, we could quantify this downdraft-updraft combination based on the height and period. Using this quantification and wavelet variance in different weather conditions, we showed the essential period from 0 to 0.25 min, 2 to 4 min, and 4 to 8 min of this microscale downdraft-updraft combination.

Anorexia is a common symptom in older patients undergoing hemodialysis (HD) and has become a serious problem in dialysis facilities with the aging of patients. Polypharmacy, defined as the prescription of several medications, is known to cause drug-induced anorexia. Although polypharmacy is also common in older patients undergoing HD, only a few studies have examined the association between anorexia and polypharmacy. This study used the Simplified Nutritional Appetite Questionnaire for Japanese Elderly (SNAQ-JE) to evaluate patients’ appetite, and examined its association with medications. This cross-sectional study included 233 patients (aged ≥65 years) who underwent HD in October 2021. Among the 233 patients (median age, 73.0 [interquartile range (IQR), 69.0–80.5] years; men, 57.3%; median dialysis vintage, 62.0 [IQR, 30.0–122.0] months), 116 and 117 were classified into the poor (SNAQ-JE total score ≤14) and good (>14) appetite groups, respectively. Although the total number of medications prescribed was not significantly different between the two groups (p = 0.12), the number of antihypertensive drugs was significantly lower (p = 0.03), and that of sleeping medications was significantly higher (p = 0.002) in the poor appetite group. Multivariable logistic regression analysis showed that the number of sleeping medications was associated with poor appetite (odds ratio, 2.08; 95% confidence interval, 1.32–3.27; p < 0.001). The findings suggest that the number of sleeping medications is an important contributing factor to poor appetite in older patients undergoing HD. A proper and regular review of prescriptions may be necessary to improve anorexia.
