Medical institutions of China still face two challenges in hospital infections currently: one challenge is from infection, including infectious diseases, multidrug-resistant bacteria healthcare-associated infection (HAI), and classic HAI; the another challenge comes from the management of HAI in medical institutions, such as lack of full-time staff and insufficient capacity, inadequate infection control organizations, insufficient awareness of infection control among medical staff, and unbalanced development. To cope with these severe challenges, we must do the following three aspects: establishing the discipline of HAI, and improving people’s infection control ability through human-orienting; improving the management organization and system of HAI; improving the awareness of infection control among all medical staff, carrying out scientific and orderly infection prevention and control work in accordance with the law, and adhering to evidence-based infection control.
At present, there has been no report in China that novel coronavirus specific immune globulin has been used to treat coronavirus disease 2019 (COVID-19). Recently, we had successfully treated one COVID-19 patient with intravenous injection of human immunoglobulin (COVID-19-IVIG). The female patient, aged 57 years, had clinical diagnosis: (1) COVID-19, common type; (2) postoperative colon cancer; (3) leukopenia; (4) low cellular immunity. 75 mL COVID-19 human immunoglobulin (Sinoptic Wuhan Blood Products Co., Ltd.) was intravenously injected twice. The patient was hospitalized for 49 days and had a good prognosis.
Most patients with coronavirus disease 2019 (COVID-19) have a good prognosis, but a certain proportion of the elderly and people with underlying diseases are still prone to develop into severe and critical COVID-19. Kidney is one of the common target organs of COVID-19. Acute kidney injury (AKI) is a common complication of severe COVID-19 patients, especially critical COVID-19 patients admitted to intensive care units. AKI associated with COVID-19 is also an independent risk factor for poor prognosis in patients. This article mainly focuses on the epidemiological data, possible pathogenesis, diagnostic criteria, and prevention and treatment based on the 5R principle of AKI associated with COVID-19. It summarizes the existing evidence to explore standardized management strategies for AKI associated with COVID-19.
Objective To investigate the effect of continuous positive airway pressure (CPAP) on sleep disorder and neuropsychological characteristics in patients with early Alzheimer’s disease (AD) combined with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of forty-two early AD patients with OSAHS were randomly divided into a CPAP combined treatment group (20 cases) and a simple medicine treatment group (22 cases). The changes of neurocognitive function were assessed by Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE) and Hopkins Verbal Learning Test-revised (HVLT). Patient Health Questionnaire-9 (PHQ9) was used to evaluate the depression mood changes. The sleep characteristics and respiratory parameters were evaluated by polysomnography. The changes of the patients’ sleep status were assessed by Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). The changes of sleep status, cognitive function and mood in the CPAP combined treatment group were compared before and three months after CPAP treatment, and with the simple medicine treatment group. Results After three months of CPAP treatment, the ESS, PSQI and PHQ9 scores in the CPAP combined treatment group were significantly decreased compared with those before treatment, whereas MoCA, MMSE and HVLT (total scores and recall ) in the CPAP combined treatment group were increased compared with those before treatment (P<0.05). After CPAP treatment, the respiratory parameters apnea hypopnea index in the CPAP combined treatment group was significantly lower than that before treatment (P<0.05), and the minimum blood oxygen saturation was significantly higher than that before treatment (P<0.05). However, the sleep characteristics and parameters did not show statistically significant changes compared with those before treatment (P>0.05). The ESS, PSQI and PHQ9 scores were significantly reduced in the CPAP combined treatment group compared with the simple medicine treatment group (P<0.05), while there was no statistically significant changes of cognitive scores between the two groups (P>0.05). Conclusions The degree of low ventilation and hypoxia is alleviated, and the daytime sleepiness and depression is improved in early AD patients with OSAHS after three-month continuous CPAP treatment. Cognitive function is significantly improved, whereas there is no significant change in sleep structure disorder.
Objective To assess the combined management of lower limb chronic venous diseases according to the CEAP classification. Methods One hundred and twenty patients were classified according to the CEAP classification. Based on clinical presentation and image study, all patients were treated with combined management plan including oppression, medication and surgery. Results All 120 patients (135 limbs) were followed up in clinic, the local recurrence rate was 18.52%(25/135). Conclusion CEAP classification expounds the developing process of lower limb chronic venous diseases. With CEAP, we can avoid the blind spot in the treatment and expand the extent of combined therapy. Accordingly, CEAP classification is useful in the treatment and diagnosis of chronic venous diseases.
ObjectiveTo provide anatomical basis for vascularized pisiform transfer in the treatment of advanced avascular necrosis of the lunate (Kienb?ck’s disease) by studying its morphology and blood supply pattern based on digital technique.MethodsTwelve adult fresh wrist joint specimens were selected and treated with gelatin-lead oxide solution from ulnar or radial artery. Then the three-dimensional (3D) images of the pisiform and lunate were reconstructed by micro-CT scanning and Mimics software. The morphologies of pisiform and lunate were observed and the longitudinal diameter, transverse diameter, and thickness of pisiform and lunate were measured. The main blood supply sources of pisiform were observed. The number, diameter, and distribution of nutrient foramina at proximal, distal, radial, and ulnar sides of pisiform were recorded. The anatomic parameters of the pedicles (branch of trunk of ulnar artery, carpal epithelial branch, descending branch of carpal epithelial branch, recurrent branch of deep palmar branch) were measured, including the outer diameter of pedicle initiation, distance of pedicle from pisiform, and distance of pedicle from lunate. ResultsThere were significant differences in the longitudinal and transverse diameters between pisiform and lunate (t=6.653, P=0.000; t=6.265, P=0.000), but there was no significant difference in thickness (t= 1.269, P=0.109). The distal, proximal, radial, and ulnar sides of pisiform had nutrient vessels. The nutrient foramina at proximal side were significantly more than that at distal side (P<0.05), but there was no significant difference in the diameter of nutrient foramina between different sides (P>0.05). The outer diameter of pedicle initiation of the recurrent branch of deep palmar branch was significantly smaller than the carpal epithelial branch and descending branch of carpal epithelial branch (P<0.05). There was no significant difference in the distance of pedicle from pisiform/lunate between branch of trunk of ulnar artery and recurrent branch of deep palmar branch (P>0.05), and between carpal epithelial branch and descending branch of carpal epithelial branch (P>0.05). But the differences between the other vascular pedicles were significant (P<0.05). ConclusionThere are abundant nutrient vessels at the proximal and ulnar sides of pisiform, so excessive stripping of the proximal and ulnar soft tissues should be avoided during the vascularized pisiform transfer. It is feasible to treat advanced Kienb?ck’s disease by pisiform transfer with the carpal epithelial branch of ulnar artery and the descending branch.
Medical institutions, the last defense line for the medical treatment of coronavirus disease 2019, are crucial to avoid cross-infection in hospitals. And how to reasonably arrange patient visits and achieve early detection, early reporting, early isolation, and early treatment of patients with coronavirus disease 2019 and suspected cases at the same time is an important proposition. After the outbreak of coronavirus disease 2019, West China Hospital of Sichuan University continued to supplement and improve implementation details based on the three-level pre-examination and triage of infectious diseases, and established a three-level pre-inspection and triage management mechanism more suitable for coronavirus disease 2019, and successfully applied it. This article introduces the process and results of this outpatient three-level pre-examination and triage management optimization practice, aiming to provide an experience reference for the outpatient three-level pre-examination and triage in medical institutions.
ObjectiveTo investigate the current research status and its developing trend of Crohn’s disease (CD) in Chinese journals in the past 40 years, and to provide reference for future research on CD.MethodsWith “Crohn’s disease” as the retrieval word, the literature about CD published from January 1978 to December 2017 were retrieved in the SinoMed database. The distributions of publication dates, journals, research institutions, and regions of literature were analyzed by EndNote, Excel, MySQL, and GraphPad Prism softwares.ResultsA total of 2 140 papers matched the searching criteria, including 1 391 papers published in the core journals. The number of papers increased by year, especially in the past 20 years, the growth rate of the total number of papers every 5 years was 96.67%, 202.54%, 85.15%, and 29.35%, respectively. A total of 152 papers met the criteria of evidence-based documents, and the proportion of evidence-based articles in the total papers every 5 years was 2.54%, 3.92%, 4.69%, and 12.16%, respectively. In the respect of region distribution of literature, the first addresses of 1 060 papers were in East China, accounting for 50.36% of the total number of papers. Jiangsu Province, Guangdong Province, Shanghai, Zhejiang Province, and Beijing had published a total of 1 257 papers, accounting for 59.71% of the total number of papers. In our research field, most of the studies were conducted by teaching hospitals.ConclusionsIn the past 40 years, the output of research on CD increased significantly in China. The proportion of evidence-based articles has increased, while the number of evidence-based research still needs to be improved. The regional distribution of literature was unbalanced, and teaching hospitals played a vital role in the research field.
ObjectiveTo explore the characteristics of chest high-resolution CT in common-type coronavirus disease 2019 patients.MethodsA retrospective analysis was performed on 35 patients in the Fever Clinic of West China Hospital of Sichuan University from January 21 to February 23, 2020. According to the nucleic acid test results, the patients were divided into a nucleic acid positive group of 14 cases, and a nucleic acid negative group of 21 cases. The clinical characteristics and high-resolution CT results (including lesion distribution, morphology, density, paving stone sign, air bronchial sign, vascular thickening sign, pleural effusion and enlarged lymph nodes, etc.) of the patients in each group were compared.ResultsThere was no statistically significant difference in the ratio of males to females, age distribution, clinical symptoms, or absolute lymphocyte values between the nucleic acid positive group and the nucleic acid negative group (P>0.05). The difference in epidemiological history between the two groups was statistically significant (P<0.05). The proportions of abnormal lymphocytes and white blood cell counts in the nucleic acid negative group were higher than those in the nucleic acid positive group (66.7% vs. 28.6%, P=0.041; 42.9% vs. 7.1%, P=0.028). The proportion of air bronchial signs in the nucleic acid negative group was higher than that in the nucleic acid positive group (47.6% vs. 7.1%, P=0.023). There was no significant difference in other high-resolution CT imaging findings between the two groups (P>0.05).ConclusionsCommon-type coronavirus disease 2019 patients have certain positive findings on chest high-resolution CT imagings. In clinical practice, high-resolution CT and other factors can be combined to assist in the diagnosis of coronavirus disease 2019.
ObjectiveTo investigate the current situation of stress load and professional benefit of hemodialysis nurses during the outbreak period and the remission period of coronavirus disease 2019 (COVID-19) epidemic, and discuss the differences in stress load and professional benefit of hemodialysis nurses between the two periods.MethodsIn February 2020, 119 hemodialysis nurses from three hemodialysis centers in Sichuan Province were selected as the respondents. Using the Stress Overload Scale and the Questionnaire of Nurses’ Perceived Professional Benefits, questionnaire survey was conducted in February 2020 and April 2020, respectively. Paired-sample t test was used for analysis.ResultsA total of 109 valid questionnaires were collected. The scores of stress load of hemodialysis nurses in outbreak period and remission stage were 3.00±1.26 and 2.17±1.16, respectively, of which the scores of event load dimension were 3.49±1.15 and 2.31±1.27, respectively, and the scores of individual vulnerability dimension were 2.59±1.19 and 2.05±1.06, respectively; the professional benefit scores of hemodialysis nurses in outbreak and remission were 4.19±0.83 and 4.21±0.78, respectively. The difference in stress load of the same group of hemodialysis nurses between different time periods was statistically significant (P<0.05), while there was no significant difference in professional benefit (P>0.05).ConclusionsDuring the outbreak of COVID-19 epidemic, the stress load of hemodialysis nurses was ata medium level, and that in the remission stage of COVID-19 epidemic was at a low level; the professional benefit of nurses in the outbreak and remission period was at a high level. The stress load status of hemodialysis nurses was different between different periods of the epidemic. We should take incentive mechanism or targeted psychological intervention measures to improve the professional benefit level of nurses.
