Summary Background Coronavirus disease 2019 (COVID-19) is a global pandemic but the follow-up data of discharged patients was barely described. Aim To investigate clinical outcomes, distribution of quarantine locations and the infection status of the contacts of COVID-19 patients after discharge. Design A prospective cohort study. Methods Demographics, baseline characteristics of 131 COVID-19 patients discharged from 3 February 2020 to 21 February 2020 in Wuhan, China were collected and analyzed by reviewing the medical records retrospectively. Post-hospitalization data related to clinical outcomes, quarantine locations and close contact history were obtained by following up the patients every week up to 4 weeks. Results Fifty-three (40.05%) patients on discharge had cough (29.01%), fatigue (7.63%), expectoration (6.11%), chest tightness (6.11%), dyspnea (3.82%), chest pain (3.05%) and palpitation (1.53%). These symptoms constantly declined in 4 weeks post-discharge. Transient fever recurred in 11 (8.4%) patients. Among the discharged patients, 78 (59.5%) underwent chest CT and 2 (1.53%) showed deterioration. A total of 94 (71.8%) patients received SARS-CoV-2 retest and 8 (6.10%) reported positive. Seven (2.29%) patients were readmitted because of fever or positive SARS-CoV-2 retest. After discharge, 121 (92.37%) and 4 (3.05%) patients were self-quarantined at home or community spots, respectively, after a close contact with 167 persons in total who were free of COVID-19 at the endpoint of study. Conclusion The majority of COVID-19 patients after discharge were in the course of recovery. Readmission was required in rare cases due to suspected recurrence of COVID-19. Although no contacted infection observed, appropriate self-quarantine and regular re-examination are necessary, particularly for those who have recurred symptoms.

Abstract Background: Locking intramedullary nails and locking plates are most widely used in the treatment of 2-part and 3-part proximal humeral surgical neck fractures, however, the clinical outcomes are controversial. This study aimed to compare the clinical outcomes of treatment with these two implants in elderly patients.Methods: In this prospective cohort study with a 24-month follow-up period, from June 2014 to November 2016, a total of 53 elderly patients with 2-part and 3-part proximal humeral surgical neck fractures treated with locking intramedullary nails and locking plates were included. We analyzed the intraoperative and radiographic parameters. The American Shoulder and Elbow Surgeons (ASES) score, Constant–Murley score and range of motion (ROM) were used to evaluate shoulder function. We also assessed the visual analog scale (VAS) score and complication rate.Results: For both 2-part and 3-part proximal humeral surgical neck fractures, the nail group showed statistically significant superiority compared with the plate group in terms of the operative duration, incision length, blood loss, hemoglobin loss, neck-shaft angle (NSA) loss, time to bony union and pain. Good to satisfactory clinical outcomes were obtained with both types of implants. Significant differences were not found in the functional results or complication rate between the two groups at different time points during the follow-up period.Conclusions: Treatment with both locking intramedullary nails and locking plates achieves similar and good to satisfactory clinical outcomes in elderly patients. We favor locking intramedullary nails, especially in the treatment of 2-part proximal humeral surgical neck fractures.Trial registration: Medical Ethics Committee for Clinical Research of Zhongda hospital, ZDYJLY (2014) new No. 9.

Abstract Background Early identification of patients who are at high risk of poor clinical outcomes is of great importance in saving the lives of patients with novel coronavirus disease 2019 (COVID-19) in the context of limited medical resources. Objective To evaluate the value of the neutrophil to lymphocyte ratio (NLR), calculated at hospital admission and in isolation, for the prediction of the subsequent presence of disease progression and serious clinical outcomes (e.g., shock, death). Methods We designed a prospective cohort study of 352 hospitalized patients with COVID-19 between January 9 and February 26, 2020, in Yichang City, Hubei Province. Patients with an NLR equal to or higher than the cutoff value derived from the receiver operating characteristic curve method were classified as the exposed group. The primary outcome was disease deterioration, defined as an increase of the clinical disease severity classification during hospitalization (e.g., moderate to severe/critical; severe to critical). The secondary outcomes were shock and death during the treatment. Results During the follow-up period, 51 (14.5%) patients’ conditions deteriorated, 15 patients (4.3%) had complicated septic shock, and 15 patients (4.3%) died. The NLR was higher in patients with deterioration than in those without deterioration (median: 5.33 vs. 2.14, P < 0.001), and higher in patients with serious clinical outcomes than in those without serious clinical outcomes (shock vs. no shock: 6.19 vs. 2.25, P < 0.001; death vs. survival: 7.19 vs. 2.25, P < 0.001). The NLR measured at hospital admission had high value in predicting subsequent disease deterioration, shock and death (all the areas under the curve > 0.80). The sensitivity of an NLR ≥ 2.6937 for predicting subsequent disease deterioration, shock and death was 82.0% (95% confidence interval, 69.0 to 91.0), 93.3% (68.0 to 100), and 92.9% (66.0 to 100), and the corresponding negative predictive values were 95.7% (93.0 to 99.2), 99.5% (98.6 to 100) and 99.5% (98.6 to 100), respectively. Conclusions The NLR measured at admission and in isolation can be used to effectively predict the subsequent presence of disease deterioration and serious clinical outcomes in patients with COVID-19.
