ABSTRACT
PURPOSE: Healthcare staff operate at the forefront of the fight against COVID-19 and hence face enormous physical and mental pressures. We aim to investigate healthcare staff's mental health issues and the associated predictors during the COVID-19 pandemic. Specifically, this paper aims to identify some unique predictors of healthcare staff's mental health issues in Iran, the second country after China to experience a major COVID-19 crisis. METHODS: An online survey of 280 healthcare staff in all 31 provinces of Iran assessed staff's mental distress (K6), depression, and anxiety (PHQ-4) during April 5-20, 2020 during the COVID-19 crisis. RESULTS: Nearly a third of healthcare staff surpassed the cutoff for distress, depression, and anxiety symptoms. Females or more educated healthcare staff were more likely to experience distress. Those who were unsure whether they had COVID-19 were more likely to experience distress and depression symptoms. The number of COVID-19 cases among a healthcare worker's colleagues or friends positively predicted the worker's anxiety symptoms. Amongst healthcare staff, doctors were less likely than radiology technologists to experience distress and anxiety symptoms. Technicians and obstetrics staff experienced fewer anxiety symptoms. The age and the weekly working days of healthcare staff interacted such that age is asignificant predictor of mental health issues among younger but not older healthcare staff. CONCLUSION: The identification of the predictors of mental health issues can guide healthcare organizations to screen healthcare workers who are more likely to be mentally vulnerable in the ongoing COVID-19 pandemic.
ABSTRACT
Clinical value of ultrasonic imaging in diagnosis of hypopharyngeal cancer with cervical lymph node metastasis was investigated. Eighty-nine patients who were diagnosed with hypopharyngeal cancer in Qilu Hospital of Shandong University (Qingdao) from January 2014 to June 2016 were retrospectively analyzed. Sixty-eight patients were diagnosed with hypopharyngeal cancer with cervical lymph node metastasis by pathological sections. Twenty-one patients did not have cervical lymph node metastasis. All the patients were diagnosed by palpation and ultrasound. The lymph node ultrasound images were quantified by computer, and the long/short diameter ratio, the maximum systolic velocity, blood flow resistance of the metastatic and non-metastatic patients were compared. The diagnostic efficacy of palpation and ultrasound was analyzed in the diagnosis of hypopharyngeal cancer with cervical lymph node metastasis. A correlation analysis was carried out between the image features of ultrasound and lymph node metastasis. The long/short diameter ratio, maximum systolic velocity and resistance index of patients with lymph node metastasis were significantly higher than those without lymph node metastasis, with a significant difference (P<0.05). Forty-one patients were diagnosed with lymph node metastasis by palpation, fifty-nine patients were diagnosed with lymph node metastasis by ultrasound. The sensitivity and diagnostic coincidence rate of ultrasound in diagnosis of hypopharyngeal cancer with cervical lymph node metastasis were significantly higher than those of palpation (P<0.05). Statistically significant differences were observed in lymph node internal echo types, medullary echo characteristics, envelope definition, and blood flow distribution characteristics between the metastasis group and the non-metastasis group (P<0.05). Lymph node internal echo was heterogeneous. There was no medulla, and the disordered blood flow in the lymph node predicted lymph node metastasis. Preoperative ultrasound has a high diagnostic value in diagnosis of hypopharyngeal cancer with cervical lymph node metastasis. The diagnostic results of preoperative ultrasound can be used as a reference for the diagnosis and treatment of hypopharyngeal cancer with cervical lymph node metastasis.
