Patient-Family Caregiver Concordance of Symptom Assessment for Esophageal Cancer Patients Undergoing Esophagectomy.

BACKGROUND: Esophageal cancer patients suffer from multiple and severe symptoms during the postoperative recovery period. Family caregivers play a vital role in assisting patients to cope with their symptoms. OBJECTIVE: To examine the concordance of esophageal cancer patients and their caregivers on assessing patients' symptoms after surgery and identify predictors associated with the symptom concordance. METHODS: In this cross-sectional study, 213 patient-caregiver dyads completed general information questionnaires, the Memorial Symptom Assessment Scale, the Depression Subscale of Hospital Anxiety and Depression Scale, the Mutuality Scale, and the Zarit Burden Interview (for caregivers). Data were analyzed using intraclass correlation coefficients, paired t tests, and binary logistic regression. RESULTS: At the dyad level, agreement of patients' and caregivers' reported symptoms ranged from poor to fair. At the group level, patients reported significantly higher scores than caregivers in most symptoms. Of the 213 dyads, 119 (55.9%) were identified as concordant on symptom assessment. Patients' nasogastric tube, perceived mutuality, caregivers' educational background, and dyad's communication frequency with each other could predict their concordance of symptom assessment. CONCLUSIONS: There were relatively low agreements between esophageal cancer patients and caregivers on assessing patients' symptoms, and caregivers tended to underestimate patients' symptoms. The dyad's symptom concordance was influenced by patient-, caregiver-, and dyad-related factors. IMPLICATIONS FOR PRACTICE: Having an awareness of the incongruence on assessing symptoms between esophageal cancer patients and caregivers may help healthcare professionals to comprehensively interpret patients' symptoms and develop targeted dyadic interventions to improve their concordance, contributing to optimal symptom management and health outcomes.

Risk Assessment of Chlorothalonil as a Probable Human Carcinogen on Selected Vegetables in an Eastern China Province.

Objectives: This study aimed to provide an assessment of chlorothalonil's possible carcinogenic risk posed to the public. In combination and comparison with the non-carcinogenic risk, the results hopefully could provide useful insights, early warning, and references for policy formulation. Methods: This study firstly investigated the occurrence of chlorothalonil on selected key vegetables for different scenarios, and then conducted an exposure assessment with officially published data. Lastly, both the non-carcinogenic and carcinogenic risk of chlorothalonil were calculated by using Monte-Carlo simulation. Results: Even though mean non-carcinogenic risks of chlorothalonil for all scenarios were below threshold value, the mean carcinogenic risks for maximum-risk scenario and most-likely risk scenario were mostly above threshold value. High probabilities of exceedance of threshold value existed for carcinogenic risk under all scenarios. Conclusion: Potential threat to public health existed for conventionally 'safe' pesticide if considering the possible carcinogenicity. Extra caution should be taken and the potential carcinogenic effects should be included into consideration for better protection of public health during the policy formulation process.

Direct cost of dengue hospitalization in Zhongshan, China: Associations with demographics, virus types and hospital accreditation.

BACKGROUND: Zhongshan City of Guangdong Province (China) is a key provincial and national level area for dengue fever prevention and control. The aim of this study is to analyze how the direct hospitalization costs and the length of stay of dengue hospitalization cases vary according to associated factors such as the demographics, virus types and hospital accreditation. METHOD: This study is based on retrospective census data from the Chinese National Disease Surveillance Reporting System. Totally, the hospital administrative data of 1432 confirmed dengue inpatients during 2013-2014 was obtained. A quantile regression model was applied to analyze how the direct cost of Dengue hospitalization varies with the patient demographics and hospital accreditation across the data distribution. The Length of Stay (LOS) was also examined. MAIN FINDINGS: The average direct hospitalization cost of a dengue case in this study is US$ 499.64 during 2013, which corresponded to about 3.71% of the gross domestic product per capita in Zhongshan that year. The mean of the Length of Stay (LOS) is 7.2 days. The multivariate quantile regression results suggest that, after controlling potential compounding variables, the median hospitalization costs of male dengue patients were significantly higher than female ones by about US$ 18.23 (p<0.1). The hospitalization cost difference between the pediatric and the adult patients is estimated to be about US$ 75.25 at the median (p<0.01), but it increases sharply among the top 25 percentiles and reaches US$ 329 at the 90th percentile (p<0.01). The difference between the senior (older than 64 years old) and the adult patients increases steadily across percentiles, especially sharply among the top quartiles too. The LOS of the city-level hospitals is significantly shorter than that in the township-level hospitals by one day at the median (p<0.05), but no significant differences in their hospitalization costs. CONCLUSIONS: The direct hospitalization costs of dengue cases vary widely according to the associated demographics factors, virus types and hospital accreditations. The findings in this study provide information for adopting hospitalization strategy, cost containment and patient allocation in dengue prevention and control. Also the results can be used as the cost-effective reference for future dengue vaccine adoption strategy in China.
