Finding the Best Antiviral Regimen for COVID-19: A Double-Center Retrospective Cohort Study of 207 Cases in Hunan, China.

ABSTRACT: Objective:To compare the efficacy of 3/4-drugs' group with 1-drug's or 2-drugs' groups in coronavirus disease 2019 (COVID-19). Methods:We included 207 patients confirmed with COVID-19. We compared the viral clearance rate and discharge rate at day 7, 14, 21 and 28, and median time of viral clearance and length of hospitalization in patients treated with 3/4, 1 or 2 drugs. Results:The viral clearance rates of the 3/4-drugs group at day 7, 14 and 21 were significantly lower than those in the 1-drug's or 2-drugs' groups (P < 0.05). The median viral clearance days in 3/4-drugs group (13.5 days) were longer than 1-drug's or 2-drugs' groups (both were 9 days) (P < 0.001). The patients' discharge rates in the 3/4-drugs group at day 14 and 21 were significantly lower than that in the 1-drug's or 2 drugs' group (P < 0.05). The median length of hospitalization in the 3/4-drugs group was 17 days, which was significantly longer than 11 days in the 1-drug group and 13 days in the 2-drug group (P < 0.05). Conclusion:The efficacy of 1 or 2 antiviral drugs was similar in COVID-19, and 3/4-drug regimens were not associated with clinical improvement. Corticosteroid treatment and more serious disease were also risk factors for viral clearance and patients'discharge.

Project description:AimTo investigate clinical characteristics and identify risk factors for severity of coronavirus disease 2019 (COVID-19) pneumonia outside of Wuhan, China.Materials and methodsWe included 213 patients with confirmed COVID-19 who had been discharged or died by 15 March 2020. We retrospectively collected epidemiological, clinical, laboratory, computed tomography imaging and outcome data. Clinical characteristics were described and relative risk factors were compared.ResultsMost clinical characteristics of this study were similar to those from studies in Wuhan, but there were lower mortality rate and milder severity. The median time from onset of symptoms to confirmation and hospitalization was 4 and 5 days, respectively. The median virus clearance and shedding times were 10 and 15 days, respectively. When the severe/critical group was compared with the mild/moderate group, significant risk factors included: older age; dyspnea; hypertension; poor appetite; fatigue; higher white cell count, neutrophil count, prothrombin time, creatine kinase, creatine kinase-MB, D-dimer, alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and C-reactive protein; and lower lymphocyte count and albumin (p < 0.05). In the intensive care unit (ICU) group compared with the non-ICU group, risk factors included: older age; chronic obstructive pulmonary disease (COPD); dyspnea; poor appetite; higher white cell count, D-dimer, ALT, AST and LDH; and lower lymphocyte count and albumin (p < 0.05). Independent risk factors associated with the severe/critical group were dyspnea [odds ratio (OR) = 19.48], ALT (OR = 6.02) and albumin (OR = 3.36). Independent risk factors associated with the ICU group were dyspnea (OR = 8.88), COPD (OR = 31.80), D-dimer (OR = 8.37), ALT (OR = 28.76) and LDH (OR = 9.95) (p < 0.05).ConclusionThe severity of COVID-19 outside Wuhan, China was milder than that within Wuhan. The clinical infective period was long, and the longest virus shedding time was 35 days. The most important risk factors were dyspnea, COPD, D-dimer, ALT, LDH and albumin.The reviews of this paper are available via the supplemental material section.

Project description:The purpose of this retrospective study was to investigate treatment options for orbital floor fractures at a Level 1 Trauma Center in Southern California. A review of 45 cases of isolated orbital floor fractures treated at the University of California at Irvine between February 2004 and April 2007 was done. Patients were retrospectively analyzed for gender, age, mechanism of injury, associated facial injuries, presenting symptoms, method of treatment, and postoperative complications. Thirty-six male patients and nine female patients were treated. Motor vehicle collision (26/45) was the most common cause of injury, and the mean age of the patients was 35.5 years (range: 15-81 years). Ecchymosis surrounding the orbital tissue was the most common presentation (38/45). Diplopia was present in 8 of 45 patients, with 1 patient requiring urgent decompression for retrobulbar hematoma. Forty-three patients underwent surgical repair; 40 underwent transconjunctival approach with lateral canthotomy; 17 underwent reconstruction with porous polyethylene Medpor (Porex Surgical, Inc., College Park, GA.); and 26 underwent reconstruction with a titanium mesh plate. Immediate postoperative complications included 12 patients with infraorbital numbness, 3 with diplopia, 1 with cellulitis, and 1 with ectropion with a subcilliary approach. Average timing of surgery of our study was 4.94 days (range, 1-20 days). Orbital floor fracture management has changed significantly over the past few decades with the introduction of new internal fixation methods and new materials for reconstructing orbital floor defects. Recommendations for surgical intervention on orbital floor fractures mostly depend on clinical examination and imaging studies. Consequences of inadequate repair of orbital floor fractures can lead to significant facial asymmetry and visual problems. Both porous polyethylene and titanium plates are effective tools for reconstructing the orbital floor. Our review demonstrates that orbital floor fractures can be repaired safely with minimal postoperative complications and confirms that transconjunctival approach to orbital floor is an effective way for exposure and prevention of ectropion that can be seen with other techniques.

Project description:BackgroundSolitary pulmonary nodules caused by nontuberculous mycobacteriosis are included as a category of pulmonary nontuberculous mycobacterium disease. Clinical characteristics, treatments and prognosis are not fully known because there are a few related reports.MethodsThis was a multi-center retrospective study of 101 cases diagnosed as solitary nodular type of nontuberculous mycobacteriosis from January 2000 to March 2017 that underwent resection at 9 related facilities belonging to the Thoracic Surgery Study Group of Osaka.ResultsThe most common pathogen was Mycobacterium avium complex (n=77, 87.5%), followed by Mycobacterium kansasii (n=8, 9.1%). Chest computed tomography results showed subpleural locations that were difficult to distinguish from lung cancer. Fluorodeoxyglucose positron emission tomography/computed tomography was performed in 58 cases and positive results were obtained in 35 (60.3%), with an average maximum standardized uptake value of 3.87. The purpose of resection in most cases was for diagnosis. The surgical procedure was wedge resection in 87, segmentectomy in 3, and lobectomy in 11, while 77 underwent thoracoscopic surgery. Postoperative complications occurred in 7 cases, though no infections caused by nontuberculous mycobacteriosis were noted. The median observation period was 27 months. A worsened condition occurred in 10 (9.9%) with Mycobacterium avium complex, though none had local recurrence.ConclusionsSolitary pulmonary nodules due to nontuberculous mycobacteriosis is difficult to diagnose based on preoperative examination results or distinguish from lung cancer. Among the present cases, none had local complications or recurrence, even in those that underwent a wedge resection, thus postoperative chemotherapy was not considered necessary if a complete resection was performed. On the other hand, some cases showed reinfection after a long period following resection, thus patients should be informed of that future possibility.
