ABSTRACT
Objectives@#The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. @*Methods@#In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. @*Results@#Participants’ mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). @*Conclusions@#The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.
ABSTRACT
Background: Breast cancer is not only the most popular in women but is also one of the main causes of death among them in many countries. In Hanoi 1999, the prevalence of breast cancer was 21.8 per 100,000 of the population and was the main cause of death in women. In Ho Chi Minh city that prevalence was 17.1 per 100,000 of the population and was the second highest cause of death in women. Objectives: To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1. Subjects and method: A retrospective study was conducted among 103 breast cancer patients with malignant tumor size \uf0a32cm, who were admitted to K Hospital and Thanh Nhan Hospital from 01/2003 to 02/2008. Results:Breast malignant tumor was usually found most frequently at the upper outer quadrant. Around 86.4% of patients who were suspected with malignant lesion by X-ray mammography. Using biopsy test for breast cancer diagnosis, the results shows that 78.6% of patients were positive, 15.6% of cases were suspected and 5.8% had wrong diagnosis. Pathologic classifications were as followed: invasive lobular carcinoma: 78.6%, intraductal carcinoma in situ (Tis): 4.9%. Conclusion: X-ray mammography and cytopathology test are useful tools for the diagnosis of breast cancer.
