INTRODUCTION

The Bachelor of Science in Nursing (BSN) program spans four years and includes general education and professional courses. Student nurses attend lecture hours, clinical duties, and related learning experiences that might be affecting their time in attending to a healthy lifestyle. Health-promoting lifestyle is a multi-dimensional pattern of activities and perceptions that begins with self-motivation and assists in promoting self-improvement and health. The domains of health-promoting lifestyle are essential factors to further improve their way of dealing with daily challenges. Multiple factors can also influence student nurses’ lifestyles, including their separation from family, busy schedules, and dietary choices. A study highlights various factors affecting student nurses' lifestyles, underscoring the need for tailored health promotion strategies and curriculum enhancements. Research into these domains can better equip future healthcare leaders. Gender, year level, and living arrangements influence student nurses' lifestyles, prompting researchers to investigate the extent of health-promoting lifestyles among them and differences based on these factors. By addressing these domains and conducting further research, nursing education and practice can better prepare future healthcare leaders to promote health and lifestyle effectively within their communities.

To determine the extent of health-promoting lifestyle among student nurses and identify the significant differences according to gender, year level, and living arrangement. 

A quantitative, descriptive research design was used with 360 respondents, employing Yamane’s formula and quota sampling. The study adopted the Health-Promoting Lifestyle II questionnaire with a validity of 0.962.

Student nurses often engage in health promoting behaviors (mean=2.56). Male student nurses reported higher scores in health responsibility, physical activity, spiritual growth, and stress management compared to female students (p=0.40). Level IV students engaged in health-promoting activities more frequently than Level I students (p=0.74). Living arrangements did not significantly impact health-promoting lifestyles (p=0.99).

No significant difference in health-promoting lifestyles among student nurses. Respondents demonstrated the least health-promoting lifestyle behaviors in the domains of health responsibility, nutrition, and physical activity. In contrast, spiritual growth, interpersonal relations, and stress management attained the highest mean scores.

BACKGROUND

Walking is widely recognized for its benefits in pain management, disability reduction, and psychological well-being, primarily due to its cost-effectiveness and accessibility. However, comprehensive qualitative insights into the full extent of its benefits remain insufficient. Chronic low back pain (CLBP) significantly impairs daily activities, requiring a multifaceted intervention approach, as advocated by the Biopsychosocial (BPS) model and the International Classification of Functioning, Disability, and Health (ICF) framework.

This systematic review aims to evaluate the perceptions and experiences related to walking among adults suffering from CLBP, understand the barriers and facilitators influencing walking behaviors, analyze behavioral patterns, and examine internal motivators for walking.

This systematic review will include both published and unpublished qualitative studies with participants aged >18 with CLBP persisting > 3 months, where walking is utilized as the primary or secondary intervention. Databases, including PubMed, EBSCO Host, Science Direct, ProQuest, MEDLINE, Epistemonikos, Cochrane Database, and Web of Science, will be searched without language or year restrictions. The screening will involve an independent dual review of the title/abstract and full texts, followed by a critical appraisal. Data extraction and synthesis will employ a meta-aggregation approach, with findings assessed via the ConQual approach.

Synthesized findings will guide evidence-based practice. Recommendations will provide actionable insights to address gaps in qualitative research on walking, promoting a holistic, patient-centered approach to treatment.

INTRODUCTION: The diagnosis of sarcopenia relies on key indicators such as handgrip strength, walking speed and muscle mass. Developing a composite index that integrates these measures could enhance clinical evaluation in older adults. This study aimed to standardise and combine these metrics to establish a z score for the sarcopenia composite index (ZoSCI) tailored for the ageing population. Additionally, we explore the risk factors associated with ZoSCI to provide insights into early prevention and intervention strategies. METHOD: This retrospective study analysed data between January 2017 and December 2021 from an elderly health programme in Taiwan, applying the Asian Working Group for Sarcopenia criteria to assess sarcopenia. ZoSCI was developed by standardising handgrip strength, walking speed and muscle mass into z scores and integrating them into a composite index. Receiver operating characteristic (ROC) curve analysis was used to determine optimal cut-off values, and multiple regression analysis identified factors influencing ZoSCI. RESULTS: Among the 5047 participants, the prevalence of sarcopenia was 3.7%, lower than the reported global prevalence of 3.9-15.4%. ROC curve analysis established optimal cut-off points for distinguishing sarcopenia in ZoSCI: -1.85 (sensitivity 0.91, specificity 0.88) for males and -1.97 (sensitivity 0.93, specificity 0.88) for females. Factors associated with lower ZoSCI included advanced age, lower education levels, reduced exercise frequency, lower body mass index and creatinine levels. CONCLUSION This study introduces ZoSCI, a new compo-site quantitative indicator for identifying sarcopenia in older adults. The findings highlight specific risk factors that can inform early intervention. Future studies should validate ZoSCI globally, with international collaborations to ensure broader applicability.

BACKGROUND: Visual input significantly influences cerebral activity related to locomotor navigation, although the underlying mechanism remains unclear. This study aimed to analyze the effects of chronic visual impairment and its rehabilitation on sensorimotor integration during level walking in patients with age-related cataract. METHODS: This prospective case series enrolled 14 female patients (68.4 ± 4.7 years) with age-related cataract, scheduled for consecutive cataract surgeries at the Department of Ophthalmology in Peking University Third Hospital from June 2019 to June 2020. Electroencephalogram (EEG) signals during level walking were recorded using a portable EEG system before and 4 weeks after visual restoration. Walking speed was assessed using the Footscan system. Spectral power of the theta and alpha bands was analyzed with repeated-measures analysis of variance, with Assignment (rest and walking), Phase (preoperative and postoperative), and Electrode sites (F3, Fz, F4, O1, and O2) as within-subject factors. RESULTS: Compared to the visual impairment state, theta band power significantly decreased after visual restoration (13.16 ± 1.58 μV 2vs. 23.65 ± 3.48 μV 2 , P = 0.018). Theta activity was notably reduced during walking (17.24 ± 2.43 μV 2vs. 37.86 ± 6.62 μV 2 , P = 0.017), while theta power at rest was not significantly different between the two phases (9.44 ± 1.24 μV 2vs. 9.08 ± 1.74 μV 2 , P = 0.864). Changes in walking speed were correlated with alterations in theta power at electrode sites of O1 ( r = -0.574, P = 0.032) and O2 ( r = -0.648, P = 0.012). Alpha band power remained stable during walking and was unaffected by visual status. CONCLUSIONS Chronic visual impairment from age-related cataract triggers enhanced cerebral activation of sensorimotor integration to compensate for visual decline during locomotion. This cerebral over-activation is effectively alleviated by visual restoration.

Resistance training promotes protein synthesis and hypertrophy, enhancing strength of skeletal muscle through the activation of the mammalian target of rapamycin (mTOR) and the subsequent increases of ribosome biogenesis and translation capacity. Recent studies indicate that resistance training has positive effects on physical fitness and illness treatment, yet the mechanisms underlying hypertrophic adaptation remain insufficiently understood. Human studies focused on the correlation between mTOR signals and hypertrophy-related protein production, while animal research demonstrated that mTOR complex 1 (mTORC1) is the main regulator of resistance training induced-hypertrophy. A number of upstream factors of mTORC1 have been identified, while the downstream mechanisms involved in the resistance training induced-hypertrophy are rarely studied. mTORC1 regulates the activation of satellite cells, which fuse with pre-existing fibers and contribute to hypertrophic response to resistance training. This article reviews the research progress on the mechanism of skeletal muscle hypertrophy caused by resistance training, analyzes the role of mTOR-related signals in the adaptation of skeletal muscle hypertrophy, and aims to provide a basis for basic research on muscle improvements through resistance training.

The purpose of the present study was to investigate the effects of resistance combined with aerobic chrono-exercise on the common carotid artery elasticity and hemodynamics. 24 healthy young men (21.96±0.43 years old) underwent a single acute resistance combined with aerobic exercise intervention at eight time periods (6, 8, 10, 12, 14, 16, 18, and 20 o'clock). The axial flow velocity and diameter waveforms of the common carotid artery were measured, and the hemodynamics were calculated using the classical hemodynamic theory before exercise, immediately after exercise, 10 min and 20 min after exercise. The results showed that during exercise recovery, systolic and mean pressures decreased more markedly after exercise at 8 o'clock (P < 0.05); At 20 min post-exercise, arterial stiffness index and pressure-strain elastic modulus after exercise at 6 o'clock were reduced compared with the resting state, but were significantly elevated after exercise at 20 o'clock (P < 0.05). Immediately after exercise, the pressure rise was higher after exercise at 6 o'clock and the mean wall shear stress was higher after exercise at 20 o'clock (P < 0.05). These results suggest that resistance combined with aerobic chrono-exercise produces different effects on common carotid artery hemodynamics in young men. A single acute session of resistance combined with aerobic exercise at 8 o'clock is more effective in lowering blood pressure. Exercise at 6 o'clock is beneficial to improve arterial elasticity but is not recommended for young male individuals with cardiovascular disease risks because of the excessive increase in blood pressure immediately after exercise. Exercise at 20 o'clock is more effective in improving wall shear stress but is accompanied by elevated arterial stiffness indices and pressure-strain elastic modulus. These results provide a scientific basis for healthy young men in choosing the time of exercise by exploring the common carotid artery elasticity and hemodynamic-related indices.

The zebrafish model has attracted much attention due to its strong reproductive ability, short research cycle, and ease of maintenance. It has always been an important vertebrate model system, often used to carry out human disease research. Its motor behavior features have the advantages of being simpler, more intuitive, and quantifiable. In recent years, it has received widespread attention in the study of traditional Chinese medicine(TCM)for the treatment of sleep disorders, neurodegenerative diseases, fatigue, epilepsy, and other diseases. This paper reviews the characteristics of zebrafish motor behavior and its applications in the pharmacodynamic verification and mechanism research of TCM extracts, active ingredients, and TCM compounds, as well as in active ingredient screening and safety evaluation. The paper also analyzes its advantages and disadvantages, with the aim of improving the breadth and depth of zebrafish and its motor behavior applications in the field of TCM research.

OBJECTIVE: To investigate the load distribution on the more painful and less painful limbs in patients with mild-to-moderate and severe bilateral knee osteoarthritis (KOA) and explore the compensatory mechanisms in both limbs among bilateral KOA patients with different severity levels. METHODS: A total of 113 participants were enrolled between July 2022 and September 2023. This cohort comprised 43 patients with mild-to-moderate bilateral KOA (Kellgren-Lawrence grade 2-3), 43 patients with severe bilateral KOA (Kellgren-Lawrence grade 4), and 27 healthy volunteers (healthy control group). The visual analogue scale (VAS) score for pain, the Hospital for Special Surgery (HSS) score, passive knee range of motion (ROM), and hip-knee-ankle angle (HKA) were used to assess walking pain intensity, joint function, and lower limb alignment in KOA patients, respectively. Motion trajectories of reflective markers and ground reaction force data during walking were captured using a gait analysis system. Musculoskeletal modeling was then employed to calculate biomechanical parameters, including the peak knee adduction moment (KAM), KAM impulse, peak joint contact force (JCF), and peak medial/lateral contact forces (MCF/LCF). Statistical analyses were performed to compare differences in clinical and gait parameters between bilateral limbs. Additionally, one-dimensional statistical parametric mapping was utilized to analyze temporal gait data. RESULTS: Mild-to-moderate KOA patients showed the significantly higher HSS score (67.7±7.9) than severe KOA patients (51.9±8.9; t=8.747, P<0.001). The more painful limb in all KOA patients exhibited significantly greater HKA and higher VAS scores compared to the less painful limb ( P<0.05). While bilateral knee ROM did not differ significantly in mild-to-moderate KOA patients ( P>0.05), the severe KOA patients had significantly reduced ROM in the more painful limb versus the less painful limb ( P<0.05). Healthy controls showed no significant bilateral difference in any biomechanical parameters ( P>0.05). All KOA patients demonstrated longer stance time on the less painful limb ( P<0.05). Critically, severe KOA patients exhibited significantly higher peak KAM, KAM impulse, and peak MCF in the more painful limb ( P<0.05), while mild-to-moderate KOA patients showed the opposite pattern with lower peak KAM and KAM impulse in the more painful limb ( P<0.05) and a similar trend for peak MCF. CONCLUSION Patients with mild-to-moderate KOA effectively reduce load on the more painful limb through compensatory mechanisms in the less painful limb. Conversely, severe bilateral varus deformities in advanced KOA patients nullify compensatory capacity in the less painful limb, paradoxically increasing load on the more painful limb. This dichotomy necessitates personalized management strategies tailored to disease severity.

PURPOSE: To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures. METHODS: A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test. RESULTS: During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (all p > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients. CONCLUSION Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

Multimorbidity of chronic diseases is one of the most common health issues among older adults, and the resulting demand for long-term medical care and management imposes a considerable burden on healthcare systems. Muscle strength, a core indicator of overall health status, is closely associated with the risk of developing multimorbidity of chronic diseases in older adults. Decline in muscle strength not only increases the risk of multimorbidity of chronic diseases but also interacts with it to exacerbate disease burden. In older adults with existing multimorbidity of chronic diseases, muscle strength decline can impair physical function and quality of life, leading to a vicious cycle of disease progression and physical disability. Strength training can help prevent multimorbidity, with potential mechanisms including the promotion of anti-inflammatory effects and enhancement of mitochondrial energy metabolism. This review summarizes the impact of muscle strength decline on multimorbidity of chronic diseases in older adults and the effectiveness and potential mechanisms of exercise interventions, providing evidence to delay muscle strength decline, prevent the occurrence and progression of multimorbidity of chronic diseases, and improve quality of life in older adults.
