Work Ability Index and Work Ability Score: A Comparation between both Scores in a Persistent COVID-19 Cohort

Aims: The present study aims to compare the assessment of work ability based on the use of the Work Ability Index (WAI) with another questionnaire base only on the use of WAI’s first item, termed as the “Work Ability Score” (WAS). Study design: A cohort of 384 Spanish workers included in a Post COVID-19 condition or persistent COVID-19 multicenter research was utilized. Place and Duration of Study: This cohort was enlisted in four hospitals (Hospital Universitario 12 de Octubre, Madrid;Hospital Universitario Virgen Macarena, Sevilla, Andalucía;Hospital Universitario Gregorio Marañón, Madrid and Complejo Asistencial Universitario de Salamanca, Castilla y León), since 2021 until 2022. Methodology: 384 Spanish workers (176 men and 208 women;aged 20 to 70 years) with Post COVID-19 condition or persistent COVID-19 were included. Descriptive analysis of primary scores was conducted. Given the non-normal distribution of data, the Mann-Whitney and Kruskal-Wallis tests were employed. Spearman and Kendall correlations were employed to assess the relationship between WAI and WAS, also used weighted Kappa to estimate the degree agreement between WAI and WAS. Logistic regression models were utilized to study determinants influencing WAI and WAS, categorized as poor or moderate. Results: WAI had an average score of 32.98 (SD = 10.28), whereas WAS had an average of 5.95 (SD = 2.77). Significant differences were observed in both WAI and WAS across the same variables. Strong and statistically significant correlations were evident between WAI and WAS (rs = 0.83, p < 0.001). All the variables used in the logistic regression model (gender, the sector employment, and previous chronic diseases) were statistically significant in both questionnaires. Conclusion: WAS questionnaire could be used as a tool for reliable assessment of work ability among Spanish workers with Post COVID-19 condition or Persistent CO-VID-19.

COVID-19 patient with an incubation period of 27 d:A case report

BACKGROUND As a highly contagious disease,coronavirus disease 2019(COVID-19)is wreaking havoc around the world due to continuous spread among close contacts mainly via droplets,aerosols,contaminated hands or surfaces.Therefore,centralized isolation of close contacts and suspected patients is an important measure to prevent the transmission of COVID-19.At present,the quarantine duration in most countries is 14 d due to the fact that the incubation period of severe acute respiratory syndrome coronavirus type 2(SARS-CoV-2)is usually identified as 1-14 d with median estimate of 4-7.5 d.Since COVID-19 patients in the incubation period are also contagious,cases with an incubation period of more than 14 d need to be evaluated.CASE SUMMARY A 70-year-old male patient was admitted to the Department of Respiratory Medicine of The First Affiliated Hospital of Harbin Medical University on April 5 due to a cough with sputum and shortness of breath.On April 10,the patient was transferred to the Fever Clinic for further treatment due to close contact to one confirmed COVID-19 patient in the same room.During the period from April 10 to May 6,nucleic acid and antibodies to SARS-CoV-2 were tested 7 and 4 times,respectively,all of which were negative.On May 7,the patient developed fever with a maximum temperature of 39℃,and his respiratory difficulties had deteriorated.The results of nucleic acid and antibody detection of SARS-CoV-2 were positive.On May 8,the nucleic acid and antibody detection of SARS-CoV-2 by Heilongjiang Provincial Center for Disease Control were also positive,and the patient was diagnosed with COVID-19 and reported to the Chinese Center for Disease Control and Prevention.CONCLUSION This case highlights the importance of the SARS-CoV-2 incubation period.Further epidemiological investigations and clinical observations are urgently needed to identify the optimal incubation period of SARS-CoV-2 and formulate rational and evidence-based quarantine policies for COVID-19 accordingly.

Cardiovascular sequelae in post-COVID-19 patients with moderate to severe CT severity score: A follow-up study

Objective:To study cardiovascular sequelae of post-COVID-19 patients with moderate to severe computed tomography(CT)severity score.Methods:A prospective,non-randomized,observational study was conducted on 100 post-COVID-19 patients with moderate to severe CT severity scores from January 2021 to December 2021.Fifty-nine were male[mean age(54.1±12.2)years]and 41 were female[mean age(46.9±15.1)years].Patients with previous cardiovascular disease,previous chronic lung disease,and pre-existing primary or secondary pulmonary hypertension were excluded.Patients were examined,and serial electrocardiogram and 2D echocardiography were performed to detect any cardiovascular abnormality.Results:Post-COVID-19 patients had persistent symptoms,the most common being fatigue(59%).Most of these symptoms were relieved on follow-up.A rise in systolic,diastolic blood pressure,and pulse rate was observed.The electrocardiographic evaluation revealed ST-T segment changes,sinus tachycardia,ventricular hypertrophy,and arrhythmias among a considerable number of patients.On echocardiography,left ventricular diastolic dysfunction was most common(43%).Pulmonary hypertension,as evidenced by elevated pulmonary artery systolic pressure,was seen in 15%of patients.Conclusions:The present findings reveal an increased incidence of cardiovascular complications after recovery from COVID-19 infection in those without pre-existing cardiovascular or chronic lung disease.

Stressors in Nurse Students’ Formation in the New Normality Post COVID-19

Background: Mental health has been impaired and at risk due to the worldwide COVID-19 pandemic. The consequences due to confinement impacted every scenario, which directly influenced the daily routine of nurse students;in each setting students faced stressors that trigger fear, anxiety and others, since being in confinement learning of topics moved to the home, laboratory practices in hospitals were cancelled leaving the room that is uncertain up to their return to in-person activities. It is important to highlight the need for innovation and strengthening of theoretical-pedagogic aspects centered at the student’s context as a human being with their own needs and problems, who will interact with others in the continuous process of health-illness. Objective: the aim was to identify the stressors in the nurse students’ formation in the new normality post-COVID-19. Methods: Qualitative and phenomenological research with 27 participants aged 20 - 25 years, nurse students of a public university. The information collection was through four focal groups of 6-7 members each, data analysis was done according to Miles & Huberman after signed informed consent of each participant, and authorized by the chairperson of the Nurse’ career. Results: Category 1, Cumulative stressors with sub-categories 1.1 Uncertainty, 1.2 Isolation, 1.3 Invisibility, 1.4 Mockery, 1.5 Exclusion. Category 2, Expectancy states with sub-categories 2.1 Low self-esteem, 2.2 Insecurity, 2.3 Anxiety, 2.4 Depression, 2.5 Temporary leave, 2.6 Search for authenticity. Category 3, Internalization processes with sub-categories 3.1 Social rejection, 3.2 Self-censorship, 3.3 Discrediting, 3.4 Disempowerment. Category 4, Academic aspects affected with sub-categories 4.1 Deficient studying habits, 4.2 Deficient assimilations of knowledge, 4.3 Archived knowledge in the computer, 4.4 Absence of practice in previous semesters. Conclusion: Once identified the stressors in nurse students in the new normality post-COVID-19, it will allow the creation of settings that help in getting confidence for students, i.e., a safe surrounding promotes the development of abilities and competencies during formation, as well as recommendations of teachers in the classroom and laboratories that contribute to filling space that students perceive as empty, and to intensifying the companionship in clinical settings where students perceive most aggressiveness.

COVID-19 related biliary injury:A review of recent literature

Since its emergence in 2019,it has become apparent that coronavirus 2019(COVID-19)infection can result in multi systemic involvement.In addition to pulmonary symptoms,hepatobiliary involvement has been widely reported.Extent of hepatic involvement ranges from minor elevation in liver function tests(LFTs)to significant hepatocellular or cholestatic injury.In majority of cases,resolution of hepatic injury or improvement in LFTs is noted as patients recover from COVID-19 infection.However,severe biliary tract injury progressing to liver failure has been reported in patients requiring prolonged intensive care unit stay or mechanical ventilation.Due to the timing of its presentation,this form of progressive cholestatic injury has been referred to as COVID-19 cholangiopathy or post-COVID-19 cholangiopathy,and can result in devastating consequences for patients.COVID-19 cholangiopathy is recognized by dramatic elevation in serum alkaline phosphatase and bilirubin and radiologic evidence of bile duct injury.Cholangiopathy in COVID-19 occurs weeks to months after the initial infection and during the recovery phase.Imaging findings and pathology often resemble bile duct injury associated with primary or secondary sclerosing cholangitis.Etiology of COVID-19 cholangiopathy is unclear.Several mechanisms have been proposed,including direct cholangiocyte injury,vascular compromise,and cytokine release syndromes.This review summarizes existing data on COVID-19 cholangiopathy,including reported cases in the literature,proposed pathophysiology,diagnostic testing,and long-term implications.

Assessment of Persistence Symptoms in Recovered COVID-19 Patients by Yorkshire Rehabilitation Scale (C19‐YRS): A Cross-Sectional Study from Qassim Region, Saudi Arabia

Background: Earlier back at the beginning of COVID-19, the acute phase of infection was variable from one patient to another causing different symptoms. However, many patients are still suffering from Post COVID-19 Syndrome. Hence, this study aimed to assess the persistence of symptoms in patients who recovered from COVID-19 in the Qassim Region, Saudi Arabia. Methodology: A descriptive cross-sectional study of 413 confirmed PCR test-positive covid-19 patients enrolled in this study from the Ministry of Health Electronic Surveillance System (HESN). The Yorkshire Rehabilitation Scale (C19-YRS) checklist was used to record patients’ symptoms, functioning, and disability. Data were analyzed by the SPSS program. Functional and patient-reported outcome measures were correlated with certain items from C19-YRS, the severity of symptoms. Its distribution-based methods were used for responsiveness over time. The scaling and targeting assumptions were satisfied, and internal consistency was high (Cronbach’s α = 0.843). Results: After 4 weeks of infection, 50% of patients reported persistent symptoms such as laryngeal complications, 43.8% Swallowing changes, 31.3% fatigue, 18.8% pain, 18.8% loss of appetite, 12.5% breathlessness, and 6.3% depression, Moreover, 18.8% of patients experienced reduced mobility. At the beginning of the COVID-19 infection, fever was the most common complaint 332 (80.4%), followed by 267 (64.6%) fatigue, and loss of smell 230 (55.7%). The severity of the breathlessness symptoms was exaggerated during the patients’ walking or climbing stairs. Patients who were admitted to an intensive care unit (n = 5) were significantly elderly (P Conclusion: The study examined the severity of post covid syndrome by patients’ responsiveness to the scale items in C19-YRS. The majority of COVID-19 symptoms were still present but significantly reduced after 4 weeks of infection. Follow-up and long-term management of physical and psychological symptoms of hospitalized and non-hospitalized patients are very important.

Pulmonary arterial hypertension confirmed by right heart catheterization following COVID-19 pneumonia: A case report and review of literature

BACKGROUND Pulmonary arterial hypertension(PAH)is a disease of the arterioles resulting in an increased resistance in pulmonary circulation with associated high pressures in the pulmonary arteries,causing irreversible remodeling of the pulmonary arterial walls.Coronavirus disease 2019(COVID-19)has been associated with development of new onset PAH in the literature leading to symptoms of dyspnea,cough and fatigue that persist in spite of resolution of acute COVID-19 infection.However,the majority of these cases of COVID related PAH were diagnosed using echocardiographic data or via right heart catheterization in mechanically ventilated patients.CASE SUMMARY Our case is the first reported case of COVID related PAH diagnosed by right heart catheterization in a non-mechanically ventilated patient.Right heart catheterization has been the gold standard for diagnosis of pulmonary hypertension.Our patient had right heart catheterization four months after her initial COVID-19 infection due to persistent dyspnea.CONCLUSION This revealed new onset PAH that developed following her infection with COVID-19,an emerging sequela of the infection.

The Impact of COVID-19 Pandemic on Mother-Infant Bond: A Systematic Review

Background: The healthy bond that develops prenatally between the mother and her infant is important for the neuropsychological development and development of the child. In stressful situations and mental disorders, the development of this bond is inhibited. With this study, an attempt is made to investigate whether the COVID-19 pandemic affected the development of the mother-infant bond. Methods: We have searched in the databases, PubMed, Google Scholar, PsycINFO, from July to October 2023 and we have found 18 related articles. Results: Most studies supported a lower mother-infant attachment during the pandemic period. We also found increased rates of depressive symptoms, anxiety and post-traumatic stress during the pandemic. Conclusions: The period of the pandemic and the psychological factors were the right conditions for the reduced development of the mother-infant bond. In epidemiological outbreaks, the mental health of the mother and her relationship with the infant should be a priority for perinatal care professionals.

The importance of managing emotions and mental health in this lockdown period

With hundreds of millions of people grappling with isolation and heightened anxiety,the Novel Coronavirus pandemic is likely to have a serious universal impact on mental health worldwide,especially the elderly.Before the spread of coronavirus pneumonia all over the world,Chinese data have shown that the elderly is the most vulnerable faced with such diseases.We should pay more attention to those older people and help them manage their emotions to reduce the negative effects of social and emotional distance.

SARS-CoV2 Nsp3 protein triggers cell death and exacerbates amyloid β42-mediated neurodegeneration

Infection caused by the severe acute respiratory syndrome coronavirus 2(SARS-CoV2)virus,responsible for the coronavirus disease 2019(COVID-19)pandemic,induces symptoms including increased inflammatory response,severe acute respiratory syndrome(SARS),cognitive dysfunction like brain fog,and cardiovascular defects.Long-term effects of SARS-CoV2 COVID-19 syndrome referred to as post-COVID-19 syndrome on age-related progressive neurodegenerative disorders such as Alzheimer's disease remain understudied.Using the targeted misexpression of individual SARS-CoV2 proteins in the retinal neurons of the Drosophila melanogaster eye,we found that misexpression of nonstructural protein 3(Nsp3),a papain-like protease,ablates the eye and generates dark necrotic spots.Targeted misexpression of Nsp3 in the eye triggers reactive oxygen species production and leads to apoptosis as shown by cell death reporters,terminal deoxynucleotidyl transferase(TdT)dUTP Nick-end labeling(TUNEL)assay,and dihydroethidium staining.Furthermore,Nsp3 misexpression activates both apoptosis and autophagy mechanism(s)to regulate tissue homeostasis.Transient expression of SARS-CoV2 Nsp3 in murine neuroblastoma,Neuro-2a cells,significantly reduced the metabolic activity of these cells and triggers cell death.Misexpression of SARS-CoV2 Nsp3 in an Alzheimer's disease transgenic fly eye model(glass multiple repeats[GMR]>amyloidβ42)further enhances the neurodegenerative rough eye phenotype due to increased cell death.These findings suggest that SARS-CoV2 utilizes Nsp3 protein to potentiate cell death response in a neurodegenerative disease background that has high pre-existing levels of neuroinflammation and cell death.

成年人下呼吸道感染者痰液病原菌分布及多重耐药菌感染风险因素分析

目的探讨新型冠状病毒疾病(COVID-19)后疫情时期成人下呼吸道感染者痰标本中的病原菌分布、耐药性以及多重耐药菌(MDRO)感染的影响因素。方法回顾性分析2021年1月至2022年12月鹰潭184医院收治的316例成年人下呼吸道感染患者的临床资料,对其痰标本培养首次检出的107株病原菌进行菌种鉴定及药敏分析,依据药敏结果分为MDRO组(n=62)和非MDRO组(n=45),比较MDRO组和非MDRO组患者的临床资料,应用多因素Logistic回归分析探讨多重耐药菌感染的影响因素。结果107株病原菌中,检出比例位居前3的分别为肺炎克雷伯菌(29.91%)、大肠埃希菌(16.82%)、铜绿假单胞菌(14.95%),其中MDRO占比57.94%,非MDRO占比42.06%。肺炎克雷伯菌、大肠埃希菌、铜绿假单胞菌和鲍曼不动杆菌对头孢唑林的耐药率分别为90.63%、57.89%、88.89%和81.25%,对头孢噻肟的耐药率分别为59.38%、52.63%、72.22%和68.75%,对氨曲南的耐药率分别为46.88%、42.11%、44.44%和87.50%。多重耐药菌组患者年龄≥60岁、住院天数≥7 d、接受有创治疗、白球比值<1、血红蛋白(Hb)水平<100 g/L以及C反应蛋白(CRP)≥30 mg/L的患者比例明显高于非多重耐药组,差异均有统计学意义(P<0.05)。患者年龄≥60岁、住院天数≥7 d是成年人下呼吸道感染MDRO的危险因素(P<0.05),而Hb水平≥100 g/L是保护性因素(P<0.05)。结论COVID-19后疫情时期,成人下呼吸道感染患者病原菌分布发生变化,对第一、二代头孢菌素普遍耐药严重,MDRO占比高。患者年龄、住院天数和Hb水平是后疫情时期成人下呼吸道MDRO感染的独立风险因素,合理干预这些风险因素,有利于临床控制MDRO传播。

数据驱动下的传染病大流行期间大城市交通运行状况研究

新型冠状病毒肺炎是近百年来人类遭遇的影响范围最广的全球性大流行病,探究新冠疫情期间不同城市交通运行状况的演变规律,对当前传染病大流行情境下的交通运行至关重要,并对未来类似情形下的城市交通治理具有借鉴作用。城市交通运行状况可由交通健康指数、拥堵延时指数等数据来表征,因此本文收集疫情放开后十个大城市近一个月的拥堵延时指数、平均车速和交通健康指数等数据,通过相关性分析、线性回归、k-means聚类分析等方法,从多个角度探究城市交通健康指数与拥堵延时指数或平均车速之间的关系,据此采用拥堵延时指数来研究各城市交通运行状况。进而基于拥堵延时指数将研究时段划分为疫情影响期、疫情稳定期、复工复产期、春节影响期这四个阶段。并在早晚高峰、疫情、春节以及跨年夜等多种情境下,从工作日和节假日多方面挖掘各城市在疫情放开影响下交通状况变化的异同点。结果表明,在疫情放开和春节假期等多种复杂因素的影响下,交通健康指数仍能由拥堵延时指数或平均车速线性表征,交通健康指数存在一定程度的冗余,用拥堵延时指数等更易获取的数据就能够描述城市的交通运行状况。此外,疫情消退过程中,工作日早晚高峰出行的不均衡性较小,而节假日早晚高峰出行的不均衡性较大,达到40%。

The incubation period of COVID-19: a global meta-analysis of 53 studies and a Chinese observation study of 11 545 patients

Background:The incubation period is a crucial index of epidemiology in understanding the spread of the emerging Coronavirus disease 2019(COVID-19).In this study,we aimed to describe the incubation period of COVID-19 globally and in the mainland of China.Methods:The searched studies were published from December 1,2019 to May 26,2021 in CNKI,Wanfang,PubMed,and Embase databases.A random-efect model was used to pool the mean incubation period.Meta-regression was used to explore the sources of heterogeneity.Meanwhile,we collected 11545 patients in the mainland of China outside Hubei from January 19,2020 to September 21,2020.The incubation period ftted with the Log-normal model by the coarseDataTools package.Results:A total of 3235 articles were searched,53 of which were included in the meta-analysis.The pooled mean incubation period of COVID-19 was 6.0 days(95%confdence interval[CI]5.6–6.5)globally,6.5 days(95%CI 6.1–6.9)in the mainland of China,and 4.6 days(95%CI 4.1–5.1)outside the mainland of China(P=0.006).The incubation period varied with age(P=0.005).Meanwhile,in 11545 patients,the mean incubation period was 7.1 days(95%CI 7.0–7.2),which was similar to the fnding in our meta-analysis.Conclusions:For COVID-19,the mean incubation period was 6.0 days globally but near 7.0 days in the mainland of China,which will help identify the time of infection and make disease control decisions.Furthermore,attention should also be paid to the region-or age-specifc incubation period.

Demand for longer quarantine period among common and uncommon COVID-19 infections: a scoping review

Background:As one of the non-pharmacological interventions to control the transmission of COVID-19,determining the quarantine duration is mainly based on the accurate estimates of the incubation period.However,patients with coarse information of the exposure date,as well as infections other than the symptomatic,were not taken into account in previously published studies.Thus,by using the statistical method dealing with the interval-censored data,we assessed the quarantine duration for both common and uncommon infections.The latter type includes the presymptomatic,the asymptomatic and the recurrent test positive patients.Methods:As of 10 December 2020,information on cases have been collected from the English and Chinese databases,including Pubmed,Google scholar,CNKI(China National Knowledge Infrastructure)and Wanfang.Official websites and medias were also searched as data sources.All data were transformed into doubly interval-censored and the accelerated failure time model was applied.By estimating the incubation period and the time-to-event distribution of worldwide COVID-19 patients,we obtain the large percentiles for determining and suggesting the quarantine policies.For symptomatic and presymptomatic COVID-19 patients,the incubation time is the duration from exposure to symptom onset.For the asymptomatic,we substitute the date of first positive result of nucleic acid testing for that of symptom onset.Furthermore,the time from hospital discharge or getting negative test result to the positive recurrence has been calculated for recurrent positive patients.Results:A total of 1920 laboratory confirmed COVID-19 cases were included.Among all uncommon infections,34.1%(n=55)of them developed symptoms or were identified beyond fourteen days.Based on all collected cases,the 95th and 99th percentiles were estimated to be 16.2 days(95%Cl 15.5-17.0)and 22.9 days(21.7-24.3)respectively.Besides,we got similar estimates based on merely symptomatic and presymptomatic infections as 15.1 days(14.4-15.7)and 21.1 days(20.0-22.2).Conclusions:There are a certain number of infected people who require longer quarantine duration.Our findings well support the current practice of the extended active monitoring.To further prevent possible transmissions induced and facilitated by such infectious outliers after the 14-days quarantine,properly prolonging the quarantine duration could be prudent for high-risk scenarios and in regions with insufficient test resources.

A Prediction Framework for Turning Period Structures in COVID-19 Epidemic and Its Application to Practical Emergency Risk Management

The aim of this paper is first to establish a general prediction framework for turning(period)term structures in COVID-19 epidemic related to the implementation of emergency risk management in the practice,which allows us to conduct the reliable estimation for the peak period based on the new concept of“Turning Period”(instead of the traditional one with the focus on“Turning Point”)for infectious disease spreading such as the COVID-19 epidemic appeared early in year 2020.By a fact that emergency risk management is necessarily to implement emergency plans quickly,the identification of the Turning Period is a key element to emergency planning as it needs to provide a time line for effective actions and solutions to combat a pandemic by reducing as much unexpected risk as soon as possible.As applications,the paper also discusses how this“Turning Term(Period)Structure”is used to predict the peak phase for COVID-19 epidemic in Wuhan from January/2020 to early March/2020.Our study shows that the predication framework established in this paper is capable to provide the trajectory of COVID-19 cases dynamics for a few weeks starting from Feb.10/2020 to early March/2020,from which we successfully predicted that the turning period of COVID-19 epidemic in Wuhan would arrive within one week after Feb.14/2020,as verified by the true observation in the practice.The method established in this paper for the prediction of“Turning Term(Period)Structures”by applying COVID-19 epidemic in China happened early 2020 seems timely and accurate,providing adequate time for the government,hospitals,essential industry sectors and services to meet peak demands and to prepare aftermath planning,and associated criteria for the Turning Term Structure of COVID-19 epidemic is expected to be a useful and powerful tool to implement the so-called“dynamic zero-COVID-19 policy”ongoing basis in the practice.
