Segmental multi-frequency bioelectrical impedance analysis (s-MFBIA) has been adopted recently to evaluate the volume of breast cancer-related lymphedema (BCRL). This procedure uses the segmental phase angle (s-PhA) as an indicator of cellular integrity. In the smaller-built Asian population, the BCRL often has a small volume difference and can be overlooked by tape circumference volume measurement (TVM). ⋯ The same result was obtained after adjusting for age, body mass index, postoperative survival, and duration of lymphedema (r = 0.636, 0.653, 0.652, and 0.648, P < .001). The inter-limb PhA ratio demonstrated significant negative correlation with inter-limb ECW/TBW ratio and inter-limb volume ratio (r = -0.896, -0.562, P < .001).s-MFBIA has high consistency with the conventional TVM method, and its relation to cellular integrity by segmental PhA enables better understanding of the cellular state of the affected limb in mild- to moderate-degree BCRL. Therefore, it is clinically feasible for severity assessment and monitoring of mild- to moderate-degree BCRL in smaller-built Asian patients.

Sex-related associations among anemia, body mass index, and kidney function in Koreans: A cross-sectional study with propensity analysis.
The association between anemia and body mass index (BMI) in Koreans, considering kidney function, has not been clarified. Thus, we aimed to examine the association between anemia and BMI among Korean adults aged ≥19 years. This retrospective cross-sectional study evaluated male and female Korean adults aged ≥19 years who participated in the 5th, 6th, and 7th Korean National Health and Nutrition Examination Surveys (KNHANES) conducted between 2010 and 2017 were used. ⋯ Meanwhile, overweight men showed a significantly lower risk of anemia than did normal weight men (OR: 0.48; 95% CI: 0.33-0.70, P < .001). Anemia is associated with BMI according to sex. Compared with normal weight men, underweight men with abnormal kidney function had a significantly higher prevalence of anemia after adjusting for kidney function and sex, thus highlighting their need for careful management for anemia.

Health literacy of college freshmen in jiangsu, China: A 3-year longitudinal survey.
Health literacy (HL) has become an important public health issue and received growing attention in recent years. However, knowledge about the HL of adolescents and young adults is limited.[1] This study aimed to investigate the awareness rate of HL and its related factors among college freshmen in Jiangsu, China. And the results were used to support the promotion intervention to improve the HL of at-risk groups among this population. ⋯ Specifically, except for chronic diseases, knowledge and attitudes, knowledge and attitudes toward health-related behavior and lifestyle, health-related skill and scientific views of health, infection diseases, safety and first aid, medical care, health information awareness rate all have improved to a certain degree (P < .001). The independent factors associated with HL awareness rate were sex (odds ratio [OR] = 1.099, (1.039 -1.164)), residence (urban: OR = 1.141, (1.056∼1.234)), educational system (OR = 2.133, (1.975-2.305)), only child or not (OR = 1.087, (1.018-1.161)), family structure (OR = 1.192, (1.078-1.319)) and maternal education level (high school: OR = 1.183 (1.067-1.313); university and more: OR = 1.481 (1.324-1.658)). Awareness rate of HL of college freshmen is associated with multi-complex factors, further works are recommended to improve the HL levels of college freshmen, especially for the aspect of chronic diseases.

Predicting 72-h mortality in patients with extremely high random plasma glucose levels: A case-controlled cross-sectional study.
The risk factors associated with 72-hours mortality in patients with extremely high levels of random plasma glucose (RPG) remain unclear. To explore the risk factors predictive of 72-hours mortality in patients with extremely high RPG under heterogenos pathophysiological conditions. Retrospective, single-center, case-controlled cross-sectional study. ⋯ The sensitivity and specificity of this model was 75.5%. The independent risk factors associated with 72-hours mortality in patients with RPG ≥500 mg/dl are hypoalbuminemia, elevated CK, and presence of a metastatic solid tumour. Further research is needed to understand the mechanisms and possible interventions to prevent mortality associated with extremely high RPG.

To evaluate the learning curve of percutaneous endoscopic transforaminal lumbar discectomy (PETLD) from the novice stage to the proficient stage, we performed retrospective study for patients with lumbar disc herniation who underwent PETLD performed by a single surgeon and evaluated the surgeon's learning curve and the effect of surgical proficiency on outcomes. A total of 48 patients who underwent PETLD at the lower lumbar level (L3-S1) with a minimum 1-year follow-up were enrolled. The learning curve of the surgeon was assessed using cumulative study of operation time and linear regression analyses to reveal the correlation between operation time and case series number. ⋯ However, the late group demonstrated a more favorable postoperative volume index of the remnant disc (362.91 mm3 [95% confidence interval, 272.81-453.02] in the early group vs 161.14 mm3 [95% confidence interval, 124.31-197.97] in the late group, P < .001), and a lower complication rate related to exiting nerve root (16.0% in the early group vs 0% in the late group, P = .045). The learning curve of PETLD is not as difficult as that of other minimally invasive spine surgery technique. Although the overall outcomes were not different between the groups, the risks of incomplete decompression and exiting root injury-related complication were higher in the novice stage.
