There are inconsistencies in the literature regarding the prevalence and assessment of chemotherapy-induced peripheral neuropathy (CIPN). This study explored CIPN natural history and its characteristics in patients receiving taxane- and platinum-based chemotherapy. Multi-country multisite prospective longitudinal observational study. Patients were assessed before commencing and three weekly during chemotherapy for up to six cycles, and at 6,9, and 12 months using clinician-based scales (NCI-CTCAE; WHO-CIPN criterion), objective assessments (cotton wool test;10 g monofilament); patient-reported outcome measures (FACT/GOG-Ntx; EORTC-CIPN20), and Nerve Conduction Studies. In total, 343 patients were recruited in the cohort, providing 2399 observations. There was wide variation in CIPN prevalence rates using different assessments (14.2–53.4%). Prevalence of sensory neuropathy (and associated symptom profile) was also different in each type of chemotherapy, with paclitaxel (up to 63%) and oxaliplatin (up to 71.4%) showing the highest CIPN rates in most assessments and a more complex symptom profile. Peak prevalence was around the 6-month assessment (up to 71.4%). Motor neurotoxicity was common, particularly in the docetaxel subgroup (up to 22.1%; detected by NCI-CTCAE). There were relatively moderately-to-low correlations between scales (rs = 0.15,p < 0.05-rs = 0.48 p < 0.001), suggesting that they measure different neurotoxicity aspects from each other. Cumulative chemotherapy dose was not associated with onset and course of CIPN. The historical variation reported in CIPN incidence and prevalence is possibly confounded by disagreement between assessment modalities. Clinical practice should consider assessment of motor neuropathy for neurotoxic chemotherapy. Current scales may not be all appropriate to measure CIPN in a valid way, and a combination of scales are needed.

The hand hygiene (HH) behaviour of the general public and its effect on illnesses are issues of growing importance. Gender is associated with HH behaviour. HH efficiency is a combination of washing efficiency and hand drying, but information about the knowledge level and HH behaviour of the general public is relatively limited. The findings of this cross-sectional study can substantially contribute to the understanding on the knowledge gap and public behaviour towards HH, thereby providing information on gender-specific health promotion activities and campaigns to improve HH compliance. An epidemiological investigation by using a cross-sectional study design on the general public was conducted either via an online platform (SurveyMonkey) or paper-and-pen methods. The hand-washing and -drying questionnaire was used for data collection. A total of 815 valid questionnaires were collected. Majority of the respondents can differentiate the diseases that can or cannot be transmitted with poor HH, but the HH knowledge of the respondents was relatively inadequate. The female respondents had a significantly better HH knowledge than male respondents. The multiple regression analysis results also indicated that females had a significantly higher knowledge score by 0.288 towards HH than males after adjusting for age and education level. Although the majority of the respondents indicated that they performed hand cleaning under different specific situations, they admitted only using water instead of washing their hands with soap. More males than females dried their hands on their own clothing, whereas more females dried their hands through air evaporation. The average time of using warm hand dryers was generally inadequate amongst the respondents. Being a female, middle-aged and having tertiary education level are protective factors to improve HH knowledge. Misconceptions related to the concepts associated with HH were noted amongst the public. Self-reported practice on hand drying methods indicated that additional education was needed. The findings of this study can provide information on gender-specific health promotion activities and creative campaigns to achieve sustained improvement in HH practices.

To evaluate the sustaining effects of Tai chi Qigong in improving the physiological health for COPD patients at sixth month. A randomized controlled trial. Subjects were in three randomly assigned groups: Tai chi Qigong group, exercise group, and control group. The 206 subjects were recruited from five general outpatient clinics. Tai chi Qigong group completed a 3-month Tai chi Qigong program. Exercise group practiced breathing and walking as an exercise. Control group received usual care. Primary outcomes included six-minute walking distance and lung functions. Secondary outcomes were dyspnea and fatigue levels, number of exacerbations and hospital admissions. Tai chi Qigong group showed a steady improvement in exercise capacity (P<.001) from baseline to the sixth month. The mean walking distance increased from 298 to 349 meters (+17%). No significant changes were noted in the other two groups. Tai chi Qigong group also showed improvement in lung functions (P<.001). Mean forced expiratory volume in 1s increased from .89 to .99l (+11%). No significant change was noted in the exercise group. Deterioration was found in the control group, with mean volume decreased from .89 to .84l (-5.67%). Significant decreased in the number of exacerbations was observed in the Tai chi Qigong group. No changes in dyspnea and fatigue levels were noted among the three groups. Tai chi Qigong has sustaining effects in improving the physiological health and is a useful and appropriate exercise for COPD patients.

Sleep problems among university students are common; however, the association between many sleep-related factors and sleep behaviors is still unclear. The purpose of this study is to examine different sleep behaviors and sleep-related factors influencing such behaviors in university students. A descriptive survey was conducted on 400 university students in Hong Kong. The instruments for data collection consisted of the Pittsburgh Sleep Quality Index (PSQI), a sleep hygiene practice questionnaire, demographic data, and other sleep-related factors. The results reveal that 57.5% of the 400 university students are poor sleepers. Sex, year of study, sleep hygiene practice, and perceived adequate sleep in the past month all demonstrate significant associations with poor sleepers. A high prevalence of sleep-related problems among college students is confirmed and associated factors are identified. Students should be encouraged to follow sleep hygiene practice, adequate time management for academic and social activities, and suitable stress-relieving measures.

The aim of this study was to systematically evaluate the literature on adverse events associated with auricular therapy (AT). Case reports, case series, surveys, and all types of clinical trials reporting adverse events of AT were included. Relevant articles were mainly retrieved from 13 electronic databases and seven Chinese journals on complementary medicine. AT‐related adverse events were reported in 32 randomized controlled trials, five uncontrolled clinical trials, four case reports, and two controlled clinical trials. For auricular acupuncture, the most frequently reported adverse events were tenderness or pain at insertion, dizziness, local discomfort, minor bleeding and nausea, and so forth. For auricular acupressure, local skin irritation and discomfort, mild tenderness or pain, and dizziness were commonly reported. Skin irritation, local discomfort, and pain were detected in auricular electroacupuncture, and minor infection was identified in auricular bloodletting therapy. Most of these events were transient, mild, and tolerable, and no serious adverse events were identified. Our findings provide preliminary evidence that AT is a relatively safe approach. Considering the patient’s safety, prospective or retrospective surveys are needed in future research to gather practitioner‐reported and patient‐reported adverse events on AT, and the quality of adverse events reporting in future AT trials should be improved.
