RESUMO
Background: It remains unclear if choline intake is associated with colorectal cancer. Therefore, we examined data from the National Health and Nutrition Examination Survey (NHANES). Methods: This cross-sectional study included 32,222 U.S. adults in the 2005-2018 NHANE cycles, among whom 227 reported colorectal cancer. Dietary choline was derived from 24-h recalls. Logistic regression estimated odds of colorectal cancer across increasing intake levels, adjusting for potential confounders. Results: After adjusting for sociodemographic variables, BMI, alcohol use, smoking status, comorbidities, and dietary factors (energy, fat, fiber, and cholesterol), the odds ratio (OR) for colorectal cancer was 0.86 (95% CI: 0.69-1.06, p = 0.162) per 100 mg higher choline intake. Across increasing quartiles of choline intake, a non-significant inverse trend was observed (Q4 vs. Q1 OR: 0.76, 95%CI: 0.37 ~ 1.55, P-trend = 0.23). Subgroup analyses revealed largely consistent associations, with a significant interaction by hypertension status (P-interaction =0.022). Conclusion: In this large, nationally representative sample of U.S. adults, higher dietary choline intake was not significantly associated with colorectal cancer odds after adjusting for potential confounders. However, a non-significant inverse trend was observed. Further prospective studies are needed to confirm these findings and elucidate the underlying mechanisms.
RESUMO
BACKGROUND: On December 7, 2022, the Joint Prevention and Control Mechanism of China's State Council released the "Ten New Guidelines" to optimize the coronavirus disease 2019 (COVID-19) prevention policies further. This signaled a broader shift from "dynamic clearing" to "coexisting with the virus" nationwide. OBJECTIVE: This study aims to examine the experiences and perspectives of interdisciplinary nurses during the COVID-19 outbreak in China after the implementation of the "Ten New Guidelines". The goal is to understand the challenges faced by this unique nursing group and inform organizational support to bolster their well-being and resilience. METHODS: Two tertiary hospitals in southeastern Zhejiang Province were selected, with interdisciplinary nurses chosen as subjects. A constructivist qualitative research approach was employed, using semi-structured face-to-face interviews. Research data were collected through interviews and analyzed using content analysis. RESULTS: Fifteen interdisciplinary nurses were included in this study. The analysis revealed four main themes and nine sub-themes. The main themes were: (1) ineffective organizational support (inadequate organizational care, poor PPE, excessive workload), (2) physiological distress after contracting COVID-19 (extreme physical fatigue, leakage of urine due to severe coughing), (3) fear of being wrong (fear of being reprimanded in public, psychological anxiety), and (4) family responsibility anxiety (difficulty of loyalty and filial piety, obligations to their children). CONCLUSION: We provide new evidence that organizations must proactively address the support, training, and communication needs of staff, particularly interdisciplinary nurses, to supplement epidemic containment. This is also essential in helping mitigate the work-family conflicts such roles can create.
RESUMO
COVID-19 vaccine hesitancy remains problematic among healthcare workers. Social network influences may shape vaccine decision-making, but few studies have examined this in this critical workforce. We assessed the relationship between friends' COVID-19 vaccination attitudes and personal hesitancy among Chinese healthcare personnel. In December 2022-January 2023, a cross-sectional online survey was conducted at a tertiary hospital in China using WeChat. Of the 1832 healthcare personnel who were invited to answer the structured questionnaire, 613 (33.5%) samples had valid data for data analysis. Logistic regression examined the association between friends' hesitancy and participants' own hesitancy, adjusting for confounders. Of 613 healthcare workers included, 266 (43.4%) were hesitant. Those with hesitant friends had 6.34 times higher adjusted odds of hesitating themselves versus those without hesitant friends (95% CI 2.97-13.52). Strong associations persisted across subgroups. Chinese healthcare workers' COVID-19 vaccination hesitancy was highly influenced by perceived friends' attitudes. Fostering pro-vaccine social norms through trusted peer networks could help promote vaccine acceptance in this critical workforce.
