Objective This study focused on the application regularity of medicinal and dietary sub-stances(MDS)of traditional Chinese medicine(TCM)diet therapy during rehabilitation,in order to help patients with Corona Virus Disease 2019(COVID-19)reduce sequelae and improve their life quality.Methods The official websites of the national and provincial health committees,the website of the National Administration of Traditional Chinese Medicine,the China BioMedical Literature Database(CBM),China National Knowledge Infrastructure(CNKI),China Science and Technology Journal Database(VIP),and Wanfang Database were used to search the keywords,such as“coronavirus”“novel coronavirus pneumonia”“COVID-19”“protocol”“guideline”“consensus”and“rehabilitation period”.The search time was from the establishment of databases to July 31,2022.The prevention and control protocols of various provinces and cities were manually supplemented and screened out.The information on the frequency,property,flavor,meridian tropism,and efficacy of MDS was collected for association rule analysis through the Apriori algorithm.Hierarchical cluster analysis was performed using the Euclidean distance and longest distance.Results A total of 18 protocols were screened out,including 56 lists of TCM diet therapy,and 47 kinds of MDS with a frequency of 132 times during the rehabilitation of COVID-19.Among them,six lists of diet therapy were collected from national websites,26 from local government websites,and 24 from social and academic institution websites.The intended population can be divided into seven categories including normal recovery,lung-spleen Qi deficiency,deficiency of both Qi and Yin,spleen-stomach weakness,deficiency of Yang Qi,kidney Qi deficiency,and blood deficiency.Shanyao(Dioscoreae Rhizoma)and Lianzi(Nelumbinis Semen),followed by Dazao(Jujubae Fructus)were used most commonly in MDS,with mainly flat property,sweet flavor,and spleen and lung meridians in meridian tropism.Besides,deficiency-tonifying drugs were commonly used in MDS.Through association rule analysis,12 groups of association MDS pairs were obtained.The pair of Yiyiren(Coicis Semen)and Chenpi(Citri Reticulatae Pericarpium)had the highest Lift value,and Yiyiren(Coicis Semen)was used most frequently in the MDS category for eliminating pathogenic factors.The results of complex network analysis showed that the core MDS were Yiyiren(Coicis Semen),Shanyao(Dioscoreae Rhizoma),Huangqi(Astragali Radix),Fuling(Poria),and Dazao(Jujubae Fructus).Three core categories were classified by cluster analysis,including the category of strengthening spleen,nourishing kidney,and grasping Qi,the category of removing phlegm,abating panting,and regulating Qi,and the category of strengthening the middle-energizer and reinforcing Qi.Conclusion Based on the TCM theory,most patients during the rehabilitation of COVID-19 are in a state of lingering pathogens due to deficient vital Qi.TCM diet therapy is based on the principle of“giving both reinforcing and reducing treatment”,and the MDS combinations focus on both reinforcing the health Qi and eliminating pathogenic factors.The diet therapy mainly uses the MDS with flat property and sweet flavor,which belongs to deficiency-tonifying drugs,adding suitable MDS of pathogen-eliminating drugs according to different situations.The ultimate goal is to promote lung inflammation absorption,improve pulmonary fibrosis,increase immunity,reduce the occurrence of sequelae,and improve life quality. 展开更多

In this editorial,we comment on an article by Alhammad et al that was published in a recent issue of the World Journal of Clinical Cases(Manuscript No.:91134).We specifically focus on the mental health problems caused by coronavirus disease 2019(COVID-19),their mechanisms,and targeted rehabilitation strategies.Severe acute respiratory syndrome coronavirus 2,via its spike protein,binds to angiotensin-converting enzyme 2 and other receptors prior to infiltrating diverse cells within the central nervous system,including endothelial cells,neurons,astrocytes,and oligodendrocytes,thereby contributing to the development of mental illnesses.Epidemiological data from 2020 underscored the global upsurge in major depressive and anxiety disorders by 27.6%and 25.6%,respectively,during the pandemic.The commented research show that 30%of post-intensive care unit discharge patients with COVID-19 in the Arabic region exhibited Hospital Anxiety and Depression Scale scores that were indicative of anxiety and depression.While acknowledging psychosocial factors,such as grief and loss,it is crucial to recognize the potential neurological impact of the virus through various mechanisms.Accordingly,interventions that encompass dietary measures,health supplements,and traditional Chinese medicine with neuroprotective properties are necessary.This editorial underscores the urgency to implement comprehensive rehabilitation approaches to address the intricate interplay between COVID-19 and mental well-being. 展开更多

Functional near-infrared spectroscopy(fNIRS)was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019(COVID-19).Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis;moreover,8 min fNIRS resting-state data were collected.Based on the concentrations of oxyhemoglobin(HbO2)and deoxyhemoglobin(HbR)in the time series,the resting-state functional connection strength of the two groups of subjects,including the prefrontal cortex(PFC)and the lower limb supplementary motor area(LS),as well as the functional activity and functional connections of the primary motor cortex(M1)were calculated.The following findings were demonstrated.(1)Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest(ROIs)between the sedentary group and the exercise group,there was no significant difference in the mean functional strength of the ROIs between the two groups(p>0:05).In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs,the functional connection strengths of the right PFC and the right LS(p?0:0097),the left LS(p?0:0127),and the right M1(p?0:0305)in the sedentary group were significantly greater.The functional connection strength between the left PFC and the right LS(p?0:0312)and the left LS(p?0:0370)was significantly greater.Additionally,the functional connection strength between the right LS and the right M1(p?0:0370)and the left LS(p?0:0438)was significantly greater.(2)Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group(p>0:05)or between the sedentary group and the exercise group(p>0:05).Similarly,there was no significant difference in the mean functional connection strength of the homologous and heterologous ROIs of the two groups.Additionally,there was no significant difference in the mean ROIs functional strength between the two groups(p>0:05).Experimental results and graphical analysis based on functional connectivity indicate that in this experiment,college student participants who exhibited sedentary behaviors showed an increase in fNIRS signals.Increase in fNIRS signals among college students exhibiting sedentary behaviors may be linked to their status post-SARS-CoV-2 infection and the sedentary context,potentially contributing to the strengthened functional connectivity in the resting-state cortical brain network.Conversely,the fNIRS signals decreased for the participants with exercise behaviors,who maintained reasonable exercise routines under the same conditions as their sedentary counterparts.The results may suggest that exercise behaviors have the potential to mitigate and reduce the impacts of sedentary behavior on the resting-state cortical brain network. 展开更多

Background:Solid organ transplant(SOT)activities,such as liver transplant,have been greatly influenced by the pandemic of coronavirus disease 2019(COVID-19),a disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Immunosuppressed individuals of liver transplant recipients(LTRs)tend to have a high risk of COVID-19 infection and related complications.Therefore,COVID-19 vaccination has been recommended to be administered as early as possible in LTRs.Data sources:The keywords“liver transplant”,“SARS-CoV-2”,and“vaccine”were used to retrieve articles published in PubMed.Results:The antibody response following the 1st and 2nd doses of vaccination was disappointingly low,and the immune responses among LTRs remarkably improved after the 3rd or 4th dose of vaccination.Although the 3rd or 4th dose of COVID-19 vaccine increased the antibody titer,a proportion of patients remained unresponsive.Furthermore,recent studies showed that SARS-CoV-2 vaccine could trigger adverse events in LTRs,including allograft rejection and liver injury.Conclusions:This review provides the recently reported data on the antibody response of LTRs following various doses of vaccine,risk factors for poor serological response and adverse events after vaccination. 展开更多

BACKGROUND Psychological assessment after intensive care unit(ICU)discharge is increasingly used to assess patients'cognitive and psychological well-being.However,few studies have examined those who recovered from coronavirus disease 2019(COVID-19).There is a paucity of data from the Middle East assessing the post-ICU discharge mental health status of patients who had COVID-19.AIM To evaluate anxiety and depression among patients who had severe COVID-19.METHODS This is a prospective single-center follow-up questionnaire-based study of adults who were admitted to the ICU or under ICU consultation for>24 h for COVID-19.Eligible patients were contacted via telephone.The patient’s anxiety and depression six months after ICU discharge were assessed using the Hospital Anxiety and Depression Scale(HADS).The primary outcome was the mean HADS score.The secondary outcomes were risk factors of anxiety and/or depression.RESULTS Patients who were admitted to the ICU because of COVID-19 were screened(n=518).Of these,48 completed the questionnaires.The mean age was 56.3±17.2 years.Thirty patients(62.5%)were male.The main comorbidities were endocrine(n=24,50%)and cardiovascular(n=21,43.8%)diseases.The mean overall HADS score for anxiety and depression at 6 months post-ICU discharge was 11.4(SD±8.5).A HADS score of>7 for anxiety and depression was detected in 15 patients(30%)and 18 patients(36%),respectively.Results from the multivariable ordered logistic regression demonstrated that vasopressor use was associated with the development of anxiety and depression[odds ratio(OR)39.06,95% confidence interval:1.309-1165.8;P<0.05].CONCLUSION Six months after ICU discharge,30% of patients who had COVID-19 demonstrated a HADS score that confirmed anxiety and depression.To compare the psychological status of patients following an ICU admission(with vs without COVID-19),further studies are warranted. 展开更多

Coronavirus disease 2019(COVID-19)is a disease that caused a global pandemic and is caused by infection of severe acute respiratory syndrome coronavirus 2 virus.It has affected over 768 million people worldwide,resulting in approx-imately 6900000 deaths.High-risk groups,identified by the Centers for Disease Control and Prevention,include individuals with conditions like type 2 diabetes mellitus(T2DM),obesity,chronic lung disease,serious heart conditions,and chronic kidney disease.Research indicates that those with T2DM face a hei-ghtened susceptibility to COVID-19 and increased mortality compared to non-diabetic individuals.Examining the renin-angiotensin system(RAS),a vital regulator of blood pressure and pulmonary stability,reveals the significance of the angiotensin-converting enzyme(ACE)and ACE2 enzymes.ACE converts angiotensin-I to the vasoconstrictor angiotensin-II,while ACE2 counters this by converting angiotensin-II to angiotensin 1-7,a vasodilator.Reduced ACE2 exp-ression,common in diabetes,intensifies RAS activity,contributing to conditions like inflammation and fibrosis.Although ACE inhibitors and angiotensin receptor blockers can be therapeutically beneficial by increasing ACE2 levels,concerns arise regarding the potential elevation of ACE2 receptors on cell membranes,potentially facilitating COVID-19 entry.This review explored the role of the RAS/ACE2 mechanism in amplifying severe acute respiratory syndrome cor-onavirus 2 infection and associated complications in T2DM.Potential treatment strategies,including recombinant human ACE2 therapy,broad-spectrum antiviral drugs,and epigenetic signature detection,are discussed as promising avenues in the battle against this pandemic. 展开更多
