Health-promoting lifestyle and its predictors among health-related and non-health-related university students in Taiwan: a cross-sectional quantitative study.

BACKGROUND: University students majoring in different disciplines are believed to have different personality traits, courses exposure, and future roles, which may further affect their health behaviors and health status. The purpose of this study was to investigate the differences in health-promoting lifestyle (HPL) and its predictors among health-related and non-health-related students. METHODS: The research participants were university students in the main island of Taiwan, and a two-stage sampling approach was adopted to obtain the samples from November 2020 to March 2021. First, 37 universities were randomly selected based on the ratio of public and private universities in each region of Taiwan. Then, based on the ratio of health-related and non-health-related majors of selected university, 25-30 students were randomly drawn from each university according to the student ID number to complete self-administered questionnaires, which included items for personal factors, perceived health status (PHS), health conception (HC), and health-promoting lifestyle profile (HPLP). A total of 1062 valid questionnaires were recovered, including 458 from health-related students and 604 from non-health-related students. Chi-squared test, independent samples t-test, one-way ANOVA, Pearson product-moment correlation analysis, and multiple regression analysis were performed. RESULTS: The results showed that gender (p < 0.001), residential status (p = 0.023), body mass index (p = 0.016), and daily sleep duration (p = 0.034) of the students majoring in different disciplines were different. Health-related students having better HC (p = 0.002) and HPLP (p = 0.040) than non-health-related students. In addition, for both majors, females, low PHS scores, and low scores for functional/role, clinical, and eudaimonistic dimensions of HC were important indicators of a relatively negative HPLP, while health-related students who exercised 75 min or less per week and non-health-related students with a monthly disposable income of 15,000 TWD or less or who dined out 15 times or more per week also required attention in the promotion of HPL (health-related majors: adjusted R2 = 0.481, p < 0.001; non-health-related majors: adjusted R2 = 0.443, p < 0.001). CONCLUSIONS: Students majoring in each discipline who had poor HPLP which is mentioned above should be prioritized in the provision of appropriate exercise or nutritional support programs on campus to promote their awareness and ability to pay attention to their health.

A Prospective Randomized Study of Brain Tissue Oxygen Pressure-Guided Management in Moderate and Severe Traumatic Brain Injury Patients.

The purpose of this study was to compare the effect of PbtO2-guided therapy with traditional intracranial pressure- (ICP-) guided treatment on the management of cerebral variables, therapeutic interventions, survival rates, and neurological outcomes of moderate and severe traumatic brain injury (TBI) patients. From 2009 to 2010, TBI patients with a Glasgow coma scale <12 were recruited from 6 collaborative hospitals in northern Taiwan, excluding patients with severe systemic injuries, fixed and dilated pupils, and other major diseases. In total, 23 patients were treated with PbtO2-guided management (PbtO2 > 20 mmHg), and 27 patients were treated with ICP-guided therapy (ICP < 20 mmHg and CPP > 60 mmHg) in the neurosurgical intensive care unit (NICU); demographic characteristics were similar across groups. The survival rate in the PbtO2-guided group was also significantly increased at 3 and 6 months after injury. Moreover, there was a significant correlation between the PbtO2 signal and Glasgow outcome scale-extended in patients from 1 to 6 months after injury. This finding demonstrates that therapy directed by PbtO2 monitoring is valuable for the treatment of patients with moderate and severe TBI and that increasing PaO2 to 150 mmHg may be efficacious for preventing cerebral hypoxic events after brain trauma.

Early enteral nutrition and clinical outcomes of severe traumatic brain injury patients in acute stage: a multi-center cohort study.

Guidelines for patients with severe traumatic brain injury (sTBI) published in 2007 recommend providing early nutrition after trauma. Early enteral nutrition (EN) started within 48 h post-injury reduces clinical malnutrition, prevents bacterial translocation from the gastrointestinal tract, and improves outcome in sTBI patients sustaining hypermetabolism and hypercatabolism. The aim of this study was to examine the effect of early EN support on survival rate, Glasgow Coma Scale (GCS) score, and clinical outcome of sTBI patients. Medical records of sTBI patients with GCS scores 4-8 were recruited from 18 hospitals in Taiwan, excluding patients with GCS scores ≤3. During 2002-2010, data from 145 EN patients receiving appropriate calories and nutrients within 48 h post-trauma were collected and compared with 152 non-EN controls matched for gender, age, body weight, initial GCS score, and operative status. The EN patients had a greater survival rate and GCS score on the 7th day in the intensive care unit (ICU), and a better outcome at 1 month post-injury. After adjusting for age, gender, initial GCS score, and recruitment period, the non-EN patients had a hazard ratio of 14.63 (95% CI 8.58-24.91) compared with EN patients. The GCS score during the first 7 ICU days was significantly improved among EN patients with GCS scores of 6-8 compared with EN patients with GCS scores of 4-5 and non-EN patients with GCS scores of 6-8. This finding demonstrates that EN within 48 h post-injury is associated with better survival, GCS recovery, and outcome among sTBI patients, particularly in those with a GCS score of 6-8.

Effects of hot and cold foods on signals of heart rate variability and nail fold microcirculation of healthy young humans: a pilot study.

In traditional Chinese medicine, hot- and cold-attribute of food ingredients are a major part of dietary therapy. The aim of this study was to establish a suitable scientific methodology to define the attributes of food ingredients by investigating the relationship between food attributes and the physiological signals produced in healthy young subjects with different constitutions. Thirty subjects were grouped into hot and cold constitutions by Chinese medical doctors. Every subject took water, aged ginger tea and coconut water, which are well recognized as having neutral-, hot- and cold-attribute, respectively, on different visits. The different physiological signals induced by the samples were observed using skin and axillary temperature sensors, a heart rate variability analyzer and a laser Doppler anemometer. We found that the capillary red blood cell (RBC) velocity in nail fold microcirculation (NFM) of the subjects with hot constitution accelerated significantly after taking the hot-attribute aged ginger tea, which might be the result of elevated vagal activity leading to arteriole dilation in these subjects. In contrast, in subjects with cold constitution, capillary RBC velocity decelerated significantly and skin temperature decreased markedly after taking the cold-attribute coconut water, which might have been induced by sympathetic nerve activation causing the arteriole to be constricted. Accordingly, the use of capillary RBC velocity of NFM measured by laser Doppler anemometer may be a promising way to classify attributes of food ingredients commonly used in Chinese medicine dietary therapy in accordance with different personal constitutions.

Effect of hot-attribute aged ginger tea on chinese medical pulse condition of healthy young humans.

Young individuals typically have a dry-heat ( zào rè) constitution and feel overly stimulated. This study observes specialties on the right-bar ( yòu guan) section of the radial-arterial pulse of healthy young subjects, and investigates pulse variations induced by different attribute foods. Chinese medical doctors grouped thirty subjects into heat and non-heat constitutions. Each subject took water, aged ginger tea, and coconut water, well recognized as neutral, hot, and cold drinks, on different visits. The current study observed physiological signals induced by the samples using novel noninvasive sphygmography and a blood pressure monitor. As the baseline bigger percussion wave, dicrotic wave, and area in the sphygmogram of the non-heat constitution subjects, this work suggests that blood vessels of these subjects may be more relaxed than that of the heat constitution ones. Stroke volume increased and pulse pressure decreased in the non-heat constitution subjects after taking aged ginger tea, which may elevate arterial compliance corresponding to maintaining an estimated radial-arterial diameter in our study. However, the percussion wave widened and the valley increased in the heat constitution subjects after taking aged ginger tea. This corresponds to the markedly reduced radial-arterial diameter, indicating tighter blood vessels than the baseline status. Accordingly, this study confirms that selecting foods with attributes opposite to personal constitutions is important for reestablishing a healthy cold-heat balance within the human body. Moreover, novel noninvasive sphygmography may be a useful instrument to classify scientifically the heat personal constitution and the responses to different attribute foods.
