Malignant melanoma is considered the most serious type of skin cancer. In clinical practice, the conventional technique based on subjective visual examination has a high rate of misdiagnosis for malignant melanoma and benign nevus. Polarization imaging techniques have great potential in clinical diagnosis due to the advantages of improving sensitivity to functional structures, such as microfiber. In this paper, a set of human skin tissue sections, including 853 normal, 851 benign nevus, and 874 malignant melanoma, were analyzed and differentiated using a homemade high-fidelity Mueller matrix imaging polarimeter. The quantitative result using support vector machine algorithms confirmed that, while scalar retardance yields lower accuracy rates, vectorial retardance results in greater accuracy for both the training and testing sets. In particular, the cross-validation accuracy for the training set increased from 88.33% to 98.60%, and the prediction accuracy for the testing set increased from 87.92% to 96.19%. This tackles the limitation of the examination based on clinical experience and suggests that vectorial retardance can provide more accurate diagnostic evidence than scalar retardance. Unfortunately, it is inconvenient and time-consuming to read and analyze each component of the vectorial retardance simultaneously in the qualitative assessment. To address this clinical challenge, a color-encoded vectorial retardance imaging method was implemented. This method can provide superior tissue-specific contrast and more fiber details than scalar retardance. The anisotropic microfiber variation among different skin lesions, including the orientation and distribution, can be clearly highlighted. We believe that this work will not only enable early and rapid diagnosis of skin cancer but also provide a good observation and analysis of the state of cancer progression.

Population-Based Behavioral Risk Factors Prevention and Control: the Fundamental Strategy for Fighting NCDs

Food and nutrition literacy (FNL) plays an important role in young adults’ dietary habits and nutrition. This study aimed to investigate FNL status and its associated factors among young adults aged 15–44 years in Shenzhen.A cross-sectional survey of 5,390 participants was conducted in June 2021. FNL was measured using the Food and Nutrition Literacy Questionnaire for Chinese Adults (FNLQ). A generalized linear model was employed to analyze the factors associated with FNL.The median FNL score (total score = 100) was 68.00, which was below the adequate level of 80. FNL was divided into the two different domains of knowledge and skills, with significantly different scoring rate of 85.30 and 67.77%, respectively. The overall proportion of respondents with adequate FNL was 19.52%. The FNL score was significantly higher among the participants who were female (β = 2.665; 95% confidence interval [CI]: 2.031–3.299) and with higher education levels (β ranging from 5.632 [CI: 3.845–7.419] to 10.756 [CI: 8.973–12.538]), healthcare-related work experience (β = 4.197; CI: 3.557–4.837) and a higher economic status (β ranging from 0.753 [CI: 0.079–1.426] to 6.217 [CI: 5.208–7.227]). Those who were divorced or with an unknown marital status (β = −8.438; CI: −9.701, −7.175), abnormal body mass index (thin [β = −2.115; CI: −3.063, −1.166], overweight [β = −1.427; CI: −2.254, −0.600]), and suffering from chronic diseases (single disease [β = −3.483; CI: −4.485, −2.480], multimorbidity [β = −5.119; CI: −5.912, −4.327]) had significantly lower FNL scores.Generally, the level of FNL among young adults in Shenzhen, China, was relatively low. Thus, nutrition education programs targeted at promoting improved FNL status call for additional emphasis, especially in subgroups with lower scores.

Introduction To reduce unhealthy lifestyles in China, it is critical to implement effective strategies. Counseling provided by physicians is important for assisting patients in improving their lifestyles, and general practitioners (GPs) are the main providers of lifestyle counseling to patients. However, few studies have focused on the lifestyle counseling practices by GPs in China, particularly in regard to nutrition and physical activity. Objective The aims of this study are: (i) to examine the current practice of Chinese GPs in counseling patients regarding nutrition and physical activity; (ii) to understand the common barriers to such counseling by Chinese GPs; and (iii) to study the association between GPs’ personal lifestyle choices and their practices in lifestyle counseling. Methods A cross-sectional, self-reported online questionnaire was conducted among GPs in Hunan province, China. A total of 198 GPs completed the questionnaire. Results The majority of GPs provide nutrition and physical activity counseling to less than 40% of their patients, spending less than three minutes per counseling session. The main reported barriers to counseling on nutrition and physical activity are inadequate time and a lack of knowledge or experience. GPs primarily acquire knowledge through medical books and journals, followed by science popularization. Furthermore, GPs who maintain healthier lifestyle habits, possess a better understanding of lifestyle guidelines, conduct longer office visits, and exhibit higher self-efficacy are more likely to provide counseling to patients. Conclusion This study highlights the need for improvement in nutrition and physical activity counseling among Chinese GPs. GPs’ personal nutrition and physical activity habits may measurably influence their counseling practice. We recommend that GPs themselves adopt healthier lifestyle habits to potentially improve their counseling practice. Moreover, proactive measures should be taken to assist GPs in overcoming barriers encountered with lifestyle counseling.

Nutrition and Physical Activity Counseling by General Practitioners in China

What is already known about this topic? Since the launch of China Healthy Lifestyle for All (CHLA), each action area has been evaluated at the local level and effective results have been achieved in most areas. What is added by this report? Based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model, the study found that there is an imbalance in the development of CHLA, and some of the action goals and indicators are not satisfactory. What are the implications for public health practices? A national action evaluation index system should be built to ensure the sustainability and scientific nature of this strategy. In addition, the government needs to attach great importance to CHLA to effectively help residents take health actions.

Background At present, little is known about the risk factors of early postoperative death in patients with hepatocellular carcinoma (HCC). Methods We collected the data of patients who were diagnosed with primary liver cancer between 2010 and 2015 in the Surveillance, Epidemiology, and End Results database and further allocated them to the training set and validation set. Univariate and multivariate logistic regression analysis was used to determine the independent influencing factors of early postoperative death of HCC patients. Random forest and Least absolute shrinkage and selection operator regression analysis were used to screen out vital variables for the construction of the nomogram. It was evaluated by receiver operating characteristic curve, calibration curve and decision curve analysis. Results A total of 4154 patients were selected in this process, including 2647 patients with postoperative early death (outcome1) and 1507 patients with liver cancer-specific postoperative early death (outcome2). Surgery method, age category, marital status and tumor grade were the risk factors for early postoperative death. As for the liver cancer-specific early postoperative death, AJCC, surgery method, chemotherapy and tumor grade were independent prognostic factors. Early death and liver cancer-specific early death nomograms have an area under curves of 0.643 and 0.679 in the training set, respectively, and 0.617 and 0.688 in the validation set. The calibration curve and decision curve analysis shows that the nomograms have good performance. Conclusion This model provides an intuitive and practical tool for future studies based on large-scale cohorts by exploring the risk factors of early death in patients with HCCs undergoing surgery.
