The effect of an overall healthy lifestyle on early-onset stroke: a cross-sectional study.

BACKGROUND: The impact of an overall healthy lifestyle on early-onset stroke is still unclear. Our study thus aimed to investigate the association of overall healthy lifestyle on early-onset stroke in Chinese hospitalized stroke patients. METHODS: This retrospective study included 821 hospitalized stroke patients from the First People's Hospital of Changzhou. An overall healthy lifestyle was defined as the presence of more than 2 of the following items: healthy diet, no smoking, normal body mass index (BMI <24 kg/m2 ), engaging in moderate to high physical activity (≥3 times/week, and ≥30 minutes each time). Early-onset stroke was defined as a stroke first occurring at 50 years old or younger. RESULTS: Among all participants, there were 98 early-onset stroke patients and 723 late-onset stroke patients. Early-onset patients had a lower prevalence of overall healthy lifestyles than that of late-onset patients (P<0.001). Multivariate logistic regression revealed that an overall healthy lifestyle significantly reduced the risk of early-onset stroke. In reference to those without an overall healthy lifestyle, the multivariate-adjusted odds ratios (ORs) for early-onset stroke among participants with an overall healthy lifestyle was 0.27 [95% confidence interval (CI): 0.07-0.98]. CONCLUSIONS: In Chinese stroke patients, a healthy lifestyle was significantly associated with early-onset stroke. Individuals who were adhering to an overall healthy lifestyle had a lower risk of early-onset stroke compared to those who were not.

Effect of Intravenous Glucose Tolerance Test on Bone Turnover Markers in Adults with Normal Glucose Tolerance.

BACKGROUND It is well known that enteral nutrients result in acute suppression of bone turnover markers (BTMs), and incretin hormones are believed to play a significant role in this physiological skeletal response. However, there is limited research exploring the impact of parenteral nutrients on BTMs. Our aim was to assess the influence of intravenous glucose on BTMs in adults with normal glucose tolerance (NGT). MATERIAL AND METHODS We conducted 1-h intravenous glucose tolerance test (IVGTT) in 24 subjects with NGT. Blood samples were collected before and 5, 10, 15, 20, 30, 60 min after administration of glucose, then serum levels of bone formation marker procollagen type I N-terminal propeptide (P1NP) and resorption marker C-terminal cross-linking telopeptides of collagen type I (CTX) were measured. RESULTS During IVGTT, the fasting CTX level fell gradually and reached a nadir of 80.4% of the basal value at 60 min. Conversely, the fasting P1NP level decreased mildly and reached a nadir of 90.6% of the basal value at 15 min, then gradually increased and reached 96.6% at 60 min. The CTX-to-P1NP ratio increased slightly and reached a peak of 104.3% of the basal value at 10 min, then fell gradually and reached a nadir of 83% at 60 min. CONCLUSIONS Our study indicates that intravenous glucose results in an acute suppression of BTMs in the absence of incretin hormones. The mechanism responsible for this needs further investigation.

Relationship between Serum Lipoprotein Ratios and Insulin Resistance in Polycystic Ovary Syndrome.

Objective. To investigate the association between serum lipoprotein ratios and insulin resistance in women with polycystic ovarian syndrome (PCOS). Methods. 105 PCOS patients and 109 controls were randomly enrolled in the study. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), total testosterone (T), fasting glucose (FBG), fasting insulin (FINS), serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C) levels were checked, and then TG/HDL-C ratio, TC/HDL-C, ratio and LDL-C/HDL-C ratio were calculated. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate the insulin resistance. Results. All lipoprotein ratios were significantly higher in PCOS patients as compared to healthy controls (P < 0.05). TG/HDL-C ratio, TC/HDL-C ratio, and LDL-C/HDL-C ratio were significantly correlated with HOMA-IR (P < 0.05). The ROC curve demonstrated that TC/HDL-C ratio had higher sensitivity and specificity in diagnosing PCOS with insulin resistance. Conclusion. This study demonstrates that serum lipoprotein ratio significantly correlates with insulin resistance and can be used as the marker of insulin resistance in PCOS patients.
