The Use of Adjuvant Therapy in Preventing Progression to Severe Pneumonia in Patients with Coronavirus Disease 2019: A Multicenter Data Analysis

IMPORTANCECoronavirus disease 2019 (COVID-19) is a global pandemic associated with high mortality and effective treatment to prevent clinical deterioration to severe pneumonia has not yet been well clarified. OBJECTIVETo investigate the role of several adjuvant treatments in preventing severe pneumonia in patients with COVID-19. DESIGN, SETTING, AND PARTICIPANTSMulticenter, retrospective cohort study of 564 consecutively hospitalized patients with confirmed COVID-19 at Third Xiangya Hospital of Central South University, Changsha Public Health Treatment Center, First Hospital of Yueyang, Junshan Peoples Hospital of Yueyang, Central Hospital of Shaoyang, Central Hospital of Xiangtan, Second Hospital of Changde, Central Hospital of Loudi, and First Affiliated Hospital of University of South China in Hunan province from January 17, 2020 to February 28, 2020; The final date of follow-up was March 15, 2020. EXPOSURESNonspecific antivirals (arbidol, lopinavir/ritonavir, and interferon ), antihypertensives, and chloroquine. MAIN OUTCOMES AND MEASURESThe development of severe COVID-19 pneumonia; Demographic, epidemiological, clinical, laboratory, radiological, and treatment data were collected and analyzed. RESULTSOf 564 patients, the median age was 47 years (interquartile range, 36-58 years), and 284 (50.4%) patients were men. Sixty-nine patients (12.2%) developed severe pneumonia. Patients who developed severe pneumonia were older (median age of 59 and 45 years, respectively), and more patients had comorbidities including hypertension (30.4% and 12.3%, respectively), diabetes (17.4% and 6.7%, respectively), and cardiovascular disease (8.7% and 3.2%, respectively) and presented with fever (84.1% and 60.4%, respectively) and shortness of breath (10.1% and 3.8%, respectively) compared with those who did not. Nonspecific antiviral therapy did not prevent clinical progression to severe pneumonia, although fewer hypertensive patients on angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers (ACEI/ARB) therapy developed severe pneumonia in contrast with those on non-ACEI/ARB antihypertensive therapy (1 of 16 [6.3%] patients and 16 of 49 [32.7%] patients, respectively [difference, 26.4%; 95% CI, 1.5% to 41.3%]). Multivariate logistic regression analysis showed that hypertension without receiving ACEI/ARB therapy was an independent risk factor (odds ratio [OR], 2.07; 95% CI, 1.07 to 4.00) for developing severe pneumonia irrespective of age. Besides, none of patients treated with chloroquine developed severe pneumonia, though without significance (difference, 12.0%; 95% CI, -3.5% to 30.0%) by propensity score matching. CONCLUSIONS AND RELEVANCEHypertensive patients on ACEI or ARB may be protective from severe pneumonia in COVID-19 and hence these therapies should not be ceased unless there is a strong indication or further epidemiological evidence. Though none of the current antiviral and immunoregulation therapy showed benefit in preventing COVID-19 progression, chloroquine deserved further investigation. KEYPOINTSO_ST_ABSQuestionC_ST_ABSDoes the use of adjuvant therapy reduce progression to severe pneumonia in patients with coronavirus disease 2019 (COVID-19)? FindingsIn this retrospective, observational cohort study involving 564 patients with confirmed COVID-19, hypertension was an independent risk factor for progression to severe pneumonia irrespective of age and those on angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) therapy were less likely to develop severe COVID-19 pneumonia, while nonspecific antivirals or chloroquine did not have significant impact on clinical progression. MeaningHypertensive patients with COVID-19 should not have ACEI or ARB ceased, unless there is a strong indication or further epidemiological evidence, given its potential protective effects.

Effect of traditional Chinese medicine wine combired with electromagnetic therapy for the neck,shoulder, back and leg pain / 现代临床护理

Objectives To explore the effect of traditional Chinese medicine wine combired with electromagnetic therapy for the neck,shoulder,back and leg pain. Methods Eighty cases of patients with neck,shoulder,back and leg pain were randomly divided into 2 groups,with 40 cases in each group,treatment group was given the traditional Chinese medicine wine and electromagnetic therapy,the control group was prescribed(only with electromagnetic therapy),use the numerical rating scale to observe the effects of two groups before therapy,3 days and 7 days after therapy . Result After treatment,the pain of the treatment group was relieved significantly better than that of the control group(P<0.05). Conclusion Traditional Chinese medicine wine combired with electromagnetic therapy for the neck,shoulder,back and leg pain has satisfactory effect,and is worthy to promotion.

Study of nursing measures for foot-drop complicated after surgical trauma / 中国实用护理杂志

Objective The purpose of this study was to observe the recovery effects of nursing intervention on foot-drop complicated after surgical trauma of bone fracture, and to discuss effective nursing strategies and measures. Methods 60 cases of patients with foot-drop complicated after internal fixation of tibial fractures were randomly divided into the observation group and the control group with 30 cases in each group, the observation group used lower limb joints rehabilitation trainers for ankle passive motion, the control group used artificial methods for ankle passive motion. Ankle movement and muscle strength recovery was observed and recorded after 12 weeks in two groups. Results Ankle joint mobility and muscle strength was significantly better in the observation group than in the control group. Conclusions Using lower limb joints rehabilitation trainers for ankle passive motion showed better effect than artificial methods for ankle passive motion.

MRI Features and the Guiding Value for Operation of Cranial Base Chordoma / 医学研究杂志

Objective To explore the guiding value for operation of MRI in diagnosing the cranial base chordoma. Methods MRI features of 15 cases with cranial base chordoma, which were proved by biopsy and surgery, were retrospectively analyzed. Results Most of the cranial base chordoma were located in the middle area of the skull base such as clivus and sellar region and always invaded extensively the nerves and major intracranial vessels of skull base. All tumors were hypointense on T_2WI and enhanced more markedly, but steady heterogeneous. Conclusion MRI examination is of great clinical signifiance in delineating the location, size and extension of cranial base chordoma, and showed anatomic relation with surrounding structures such as the major intracranial vessels of skull base, which is very important in surgical planning.
