Observational Study
Complex reconstruction technique applied in advanced head and neck cancer.
Complex reconstruction skills in advanced head and neck cancer (HNC) could resolve the key problem of large defects after tumor resection. We combined the anterolateral thigh free flap, fascia lata flap, and greater saphenous vein graft in the reconstruction process of salvage surgery. Seven patients suffering from advanced HNC who experienced the failure of multiple therapeutic methods were enrolled in our study between June 2017 and January 2018. ⋯ All of the flaps were viable, but in 1 patient, oral flap edge infection and necrosis necessitated partial debridement on day 7 postoperatively. All donor sites were closed primarily. We report our experience with this surgical method for complex reconstruction in advanced HNC patients.

Cardiac masses are rare, but lead to high risk of stroke and death. Because of the different treatment methods, it is significant for clinicians to differentiate the nature of masses. Cardiac magnetic resonance (CMR) imaging has high intrinsic soft-tissue contrast and high spatial and temporal resolution and can provide evidence for differential diagnosis of cardiac masses. However, there is no evidence-based conclusion as to its accuracy. Therefore, the purpose of our study is to perform a systematic review on this issue and provide useful information for clinical diagnosis and treatment. ⋯ CRD42019137800.

End-stage renal disease (ESRD) is a major risk factor for cardiovascular disease and the prognosis after myocardial infarction (MI) is dismal. Although cardiac troponin is a key diagnostic test, troponin levels are often elevated in ESRD patients without evidence of MI. Thus, this study attempted to determine the optimal diagnostic value of high-sensitivity troponin I (hsTnI) by dialysis modality in ESRD patients. ⋯ The optimal cut-off value of hsTnI in peritoneal dialysis patients was 144 ng/L, with 100.00% sensitivity and 83.10% specificity. AUC was .943 (95% CI .893-.992). The dialysis modality should also be considered when diagnosing MI using hsTnI in ESRD patients.

Evaluation of the correlation between job stress and sleep quality in community nurses.
Chronic sleep deprivation may worsen many medical and mental health conditions, causing difficulty in the ability to function at work. Job stress may be a factor that directly correlates with the poorer sleep quality of nurses from different departments in a general hospital. However, epidemiological evaluations of sleep problems among community nurses in China are scarce, and an association between sleep problems and occupational stress has not been investigated. ⋯ Sleep disturbances in nurses were highly associated with job difficulty factor, doctor-patient relationships, psychosomatic state, environment or events, promotion or competition and total pressure scores. Sleep problems were prevalent among clinical nurses in community hospitals in China. Occupational stress negatively affects sleep quality in Chinese community nurses; the higher the stress is, the worse the sleep quality.

Many researchers use the National Health Insurance Research Database (HIRD) to publish medical papers and gain exceptional outputs in academics. Whether they also obtain excellent citation metrics remains unclear. ⋯ The AWS-based bibliometric metrics make individual weighted research evaluations possible and available for comparison. The study results of productive authors using HIRD did not support the view that higher citation metrics exist in specific disciplines.
