Avoiding crisis-driven business failure through digital dynamic capabilities. B2B distribution firms during the COVID-19 and beyond

Previous research has proposed different determinants of the success and failure of technological innovation in industrial networks. However, following the recent COVID-19 pandemic crisis, distributors have been seeking to become more agile in identifying and transforming business processes to avoid failures. Although industrial practitioners have been broadly motivated to understand the effects of pandemics on business failure, the contingency factors that affect organizations in their responses to such sudden exogenous shocks remain unclear. Inspired by a burgeoning academic interest in viewing the COVID-19 pandemic as a digital accelerator, this paper examines how B2B distribution firms have been avoiding business failure by using their dynamic capabilities (DCs) in response to the sudden exogenous shocks caused by the pandemic. Based on data drawn from interviews conducted with a sample of B2B distribution firms, we argue that capitalizing on digital DCs—digital sensing (i.e., digital mindset crafting and digital scenario planning), digital seizing (i.e., engaging in strategic agility and balancing a digital portfolio), and digital transformation (i.e., navigating the innovation ecosystem, redesigning the internal structure, and improving digital maturity), —helps to prevent business failure during a pandemic.

Conceptualizing platformed conspiracism: Analytical framework and empirical case study of BitChute and Gab

This article introduces the notion of platformed conspiracism to conceptualize reconfigured forms of conspiracy theory communication as a result of the mutual shaping between platform specificities and emergent user practices. To investigate this relational socio-technological shaping, we propose a conceptual platform-sensitive framework that systematically guides the study of platformed conspiracism. To illustrate the application of the framework, we examine how platformed conspiracism unfolds on BitChute and Gab during the COVID-19 pandemic. Our findings show that both platforms have positioned themselves as technological equivalents to their "mainstream” counterparts, YouTube and Twitter, by offering similar interfaces and features. However, given their specific services, community-based and politically marketed business models, and minimalist approaches to content moderation, both platforms provide conspiracy propagators a fertile refuge through which they can diversify their presence and profit monetarily from their supply of conspiracy theories and active connection with their followers.

Clinical evaluation of total hip arthroplasty for osteoarthropathy secondary to septic hip arthritis.

To investigate the clinical efficacy and prognosis of total hip arthroplasty (THA) in patients with osteoarthropathy secondary to septic hip arthritis. A total of 100 patients with osteoarthropathy secondary to septic hip arthritis who underwent surgery in our hospital from December 2010 to December 2021 were selected. Operative data were summarized. Moreover, preoperative and postoperative differences in Harris score, Western Ontario and McMaster Universities Osteoarthritis Index score, Visual Analogue Scale score, hip mobility were compared. Due to hospital transfer, the epidemic of COVID-2019 and other reasons, 10 patients were lost to follow-up and finally 90 patients were recorded. According to the results, the mean operation time (OT) was 1.78 ± 0.32 (hour), the mean intraoperative blood loss (BL) was 586.62 ± 31.66 (mL), the mean red blood cell (RBC) transfusion was 3.84 ± 0.75 (U), and 2 cases were positive, and 88 cases were negative for Trendelenburg sign. Postoperatively, the unequal length of the lower limbs and the Visual Analogue Scale score were significantly lower than that of the preoperative, while the Western Ontario and McMaster Universities Osteoarthritis Index score, Harris score, and hip joint range of motion were significantly higher than those of the preoperative (P < .05). At the last follow-up, all the incisions healed with no deep infections, 1 case suffered from transient sciatic nerve palsy, 2 cases had intermuscular venous thrombosis, and 2 cases who occurred hip dislocation recovered after treatment. THA surgery for osteoarthropathy secondary to septic hip arthritis has a good effect, relieving the patient's pain effectively, improving prognosis and joint mobility. For osteoarthropathy secondary to septic hip arthritis, THA may be meaningful in terms of prognosis.

Association Between the Awareness of Antiretroviral Drugs-Related Services and Drug Accessibility During the COVID-19 Pandemic Among Patients Undergoing Antiretroviral Therapy: A Cross-Sectional Study.

In a cross-sectional survey from 21 February to 6 March, 2020, we analyzed the awareness and utilization of antiretroviral drugs (ARVs)-related services among people living with HIV during the COVID-19 pandemic in Guangzhou, China. In addition, a subgroup analysis was performed among those who needed to go to hospital to access their drugs, and we explored the association between the awareness of ARVs-related services and the accessibility of ARVs. Of 375 participants, 89.9% were aware of drug-borrowing service, 90.7% were aware of drug-delivery service and 86.9% were aware of information-assistance service. Knowing about the drug-borrowing service or the information-assistance service, knowing about at least two services and knowing about all of the three services were all positively associated with ARVs accessibility. In addition, 35 (39.3%) of those who had acquired their drugs on time received them via the drug-delivery service. To some extent, the three ARVs-related services have alleviated the difficulties in accessing ARVs during the pandemic, especially the drug-delivery service.

Parents' willingness to vaccinate themselves and their children with the booster vaccine against SARS-CoV-2: A cross-sectional study in Puyang city, China.

We aimed to investigate the hesitancy and willingness of parents to vaccinate themselves and their children with a booster dose against severe acute respiratory syndrome coronavirus 2 and related factors. We conducted a cross-sectional study in Puyang city, China. The information was collected, including demographic characteristics, willingness to receive a booster dose of coronavirus disease 2019 (COVID-19) vaccine, and attitudes and concerns toward COVID-19 and vaccines. Vaccine hesitancy was assessed in individuals completing the first two doses and booster eligible, while vaccine willingness was assessed in those completing the first two doses and not yet booster eligible. Among the participants completing two primary doses while not meeting the booster criteria, 95.4% (1465/1536) and 95.0% (1385/1458) had a willingness to a booster dose of COVID-19 vaccine for themselves and their children, respectively. Among the participants who met the booster criteria, 40.3% had vaccine hesitancy. Vaccine hesitancy and unwillingness tended to occur in people who were younger, less educated, less healthy, and with unsureness of vaccines' efficacy and adverse events (AE). The younger age of children, children in poorer health, and concern about the efficacy and AE of vaccines contributed to the participants' unwillingness to vaccinate their children. We observed a high willingness to the booster dose of COVID-19 vaccine both for the parents and their children, regardless of the eligibility to a booster dose. However, 40% of people had delayed vaccination behaviors. The promotion of scientific knowledge of vaccines' effectiveness and safety is needed, especially for people in poor health and parents with young children. Timely disclosure of AE caused by COVID-19 vaccines and proper aiding offered to people encountering AE are suggested.

Efficacy and safety of integrated traditional Chinese and Western medicine against COVID-19: A systematic review and meta-analysis.

Although plenty of clinical trials have confirmed the efficacy and safety of integrated traditional Chinese and Western medicine (ITCWM) against COVID-19, the role of ITCWM remains controversial. So we conducted a systematic review and meta-analysis of published studies in eight major databases that report the outcomes of interest in COVID-19 patients receiving ITCWM. RevMan5.4 software was used for meta-analysis, while the quality of RCTs was assessed by the Cochrane risk of bias tool and the retrospective studies were assessed by Newcastle-Ottawa Scale. Eventually, a total of 53 studies with 5425 COVID-19 patients was identified. The meta-analysis results showed that ITCWM was significantly better than western medicine treatment (WMT) alone in the percentage of cases changing to severe/critical [RR = 0.40, 95%CI (0.33, 0.49), p < .00001, I2  = 10%], overall clinical effectiveness [RR = 1.26, 95% CI (1.18, 1.35), p < .00001, I2  = 50%], time to defervescencer [MD = -1.45, 95% CI (-1.82, -1.07), p < .00001, I2  = 83%], disappearing time of cough [MD = -2.11, 95% CI (-2.98, -1.25), p < .00001, I2  = 93%], time of RT-PCR negativity [MD = -3.35, 95% CI (-4.74, -1.95), p < .00001, I2  = 92%], length of hospital stay [MD = -4.05, 95% CI (-5.24, -2.85), p < .00001, I2  = 91%], improvement in CT scan [RR = 1.22, 95% CI (1.17, 1.28), p < .00001, I2  = 46%], TCM syndrome score [MD = -3.95, 95% CI (-5.07, -2.82), p < .00001, I2  = 92%], disappearance rate of fever [RR = 1.23, 95% CI (1.10, 1.38), p < .00001, I2  = 85%], disappearance rate of cough [RR = 1.43, 95% CI (1.25, 1.63), p < .00001, I2  = 60%], level of CRP [MD = -9.23, 95% CI (-10.94, -7.52), p < .00001, I2  = 97%], and WBC [MD = -9.23, 95% CI (-10.94, -7.52), p < .00001, I2  = 97%]. There is no significant difference between ITCWM and WMT in the adverse reaction rate [RR = 0.85, 95% CI(0.71, 1.03), p = .10, I2  = 25%]. Our results showed evidence of clinical efficacy and safety benefit in COVID-19 patients treated with ITCWM. In spite of some limitations, the rapidly developing global pandemic warrants further high-quality and multicenter clinical studies to confirm the contribution of ITCWM.

Conspiracy theories in digital environments: Moving the research field forward.

In the past few years, the discussion of conspiracy theories has embroiled researchers, politicians and the public alike. During the COVID-19 pandemic in particular, the term 'conspiracy theory' became a buzzword in the news media, public communication and everyday discussions. The pandemic also demonstrated that conspiratorial narratives disseminated online are not benign, obscure and eventually harmless ideas, but can mislead policy making, hinder crisis relief and public health efforts, or undermine trust in institutions and science. Factors contributing to the prevalence of conspiracy theories are complex and include psychological as well as socio-political factors. This special issue focuses specifically on the role of digital media and how they shape the dissemination and mitigation of, as well as research on, conspiracy theories. The special issue includes 13 research articles by authors from 11 countries and regions, which provide timely insights into the phenomenon of conspiracy theories with cross-cultural and cross-platform advances.

The Influencing Factors of Breastfeeding for Full-Term Singleton Within Six Months of Birth in Xi'an Before the Covid-19 Pandemic.

Objective: The study is designed to understand the situation of full-term infants breastfeeding within 6 months of birth in Xi'an before the Covid-19 pandemic and analyze the influencing factors of exclusive breastfeeding. Methods: Five hospitals in Xi'an province have been selected as research centers. Full-term infants who met the inclusion and exclusion criteria were recruited from these centers between January 1 and February 28, 2019. The feeding situation at 10 days, 42 days, 3 months, and 6 months after birth were investigated. A self-designed breastfeeding questionnaire was used for investigation and follow-up. SPSS 22.0 was applied for statistical analysis of the data. Results: The exclusive breastfeeding rate of full-term infants on days 10 and 42 and at months three and six after birth was 61.38%, 54.78%, 48.83%, and 38.78%, respectively, with a decreasing trend over time. During breastfeeding within 48 h after delivery, 1,653 cases (91.83%) of puerpera had different grades of pain, including 1,325 cases (80.16%) of mild discomfort, 321 cases (19.42%) of moderate pain, and seven cases (0.42%) of severe pain. Within 24-48 h postpartum, 1,607 (89.27%) mothers faced problems related to postpartum breastfeeding. Among them, 694 (43,19%) neonates could not be fed effectively; 665 (41.38%) mothers had wound pain and had inconvenience to turn over; 598 (37.21%) neonates were difficult to wake up; 439 (27.32%) mothers had incorrect feeding posture; 181 (11.26%) mothers experienced other problems. The Cox risk regression model showed that weight gain during pregnancy was higher than the recommended standard. Living in suburban counties was a risk factor of exclusive breastfeeding for full-term infants. Participation in breastfeeding courses during pregnancy, feeding more than eight times daily after delivery, were the protective factors of exclusive breastfeeding for full-term infants. Conclusion: The body weight gain of parturients should be controlled within a reasonable range during pregnancy. Parturients were encouraged by medical staff to participate in breastfeeding courses or watch the breastfeeding process during pregnancy to increase their self-confidence and improve the rate of exclusive breastfeeding for full-term infants. In addition, it is necessary to strengthen the publicity of breastfeeding in suburban areas to promote breastfeeding.

Berberine regulates mesangial cell proliferation and cell cycle to attenuate diabetic nephropathy through the PI3K/Akt/AS160/GLUT1 signalling pathway.

High glucose (HG) is one of the basic factors of diabetic nephropathy (DN), which leads to high morbidity and disability. During DN, the expression of glomerular glucose transporter 1 (GLUT1) increases, but the relationship between HG and GLUT1 is unclear. Glomerular mesangial cells (GMCs) have multiple roles in HG-induced DN. Here, we report prominent glomerular dysfunction, especially GMC abnormalities, in DN mice, which is closely related to GLUT1 alteration. In vivo studies have shown that BBR can alleviate pathological changes and abnormal renal function indicators of DN mice. In vitro, BBR (30, 60 and 90 µmol/L) not only increased the proportion of G1 phase cells but also reduced the proportion of S phase cells under HG conditions at different times. BBR (60 µmol/L) significantly reduced the expression of PI3K-p85, p-Akt, p-AS160, membrane-bound GLUT1 and cyclin D1, but had almost no effect on total protein. Furthermore, BBR significantly declined the glucose uptake and retarded cyclin D1-mediated GMC cell cycle arrest in the G1 phase. This study demonstrated that BBR can inhibit the development of DN, which may be due to BBR inhibiting the PI3K/Akt/AS160/GLUT1 signalling pathway to regulate HG-induced abnormal GMC proliferation and the cell cycle, supporting BBR as a potential therapeutic drug for DN.

The effects of swimming sports on the prevention and restoration of COVID-19 and its variant strains: A protocol for systematic review and meta-analysis.

INTRODUCTION: Since 2019, corona virus disease 2019 (COVID-19) has become a new round of "epidemic," which has brought about a major crisis to the world from national development, to people's life safety and mental health. Faced with the constant variation of viruses, from COVID-19 to Delta to Omicron. How to curb its further deterioration and enhance human defense against viruses is the focus of scientific researchers. From previous studies, we found that in addition to basic medical treatment, swimming with a certain amount of load and intensity can promote the ventilator of the human body, thereby playing an auxiliary and preventive role in the treatment of COVID-19 and its variant strains. METHODS: This study searched China knowledge network, Web of science, Google scholar, PubMed database to search for the relevant research on swimming prevention and treatment for COVID-19, and the deadline for searching was December 2021. Two researchers independently screened and extracted the literature, and evaluated the bias risk of the included studies. The methodological quality of the included literature was evaluated by the Chochrane bias risk assessment tool. RESULT: This study will provide new evidence for the prevention and recovery of COVID-19 and its variant strains by swimming. CONCLUSION: To provide a method to help the prevention and restoration of COVID-19 and its variant strains by swimming. INPLASY REGISTRATION NUMBER: INPLASY2021120075.

What are the risk factors of hospital length of stay in the novel coronavirus pneumonia (COVID-19) patients? A survival analysis in southwest China.

BACKGROUND: The global epidemic of novel coronavirus pneumonia (COVID-19) has resulted in substantial healthcare resource consumption. Since patients' hospital length of stay (LoS) is at stake in the process, an investigation of COVID-19 patients' LoS and its risk factors becomes urgent for a better understanding of regional capabilities to cope with COVID-19 outbreaks. METHODS: First, we obtained retrospective data of confirmed COVID-19 patients in Sichuan province via National Notifiable Diseases Reporting System (NNDRS) and field surveys, including their demographic, epidemiological, clinical characteristics and LoS. Then we estimated the relationship between LoS and the possibly determinant factors, including demographic characteristics of confirmed patients, individual treatment behavior, local medical resources and hospital grade. The Kaplan-Meier method and the Cox Proportional Hazards Model were applied for single factor and multi-factor survival analysis. RESULTS: From January 16, 2020 to March 4, 2020, 538 human cases of COVID-19 infection were laboratory-confirmed, and were hospitalized for treatment, including 271 (50%) patients aged ≥ 45, 285 (53%) males, and 450 patients (84%) with mild symptoms. The median LoS was 19 (interquartile range (IQR): 14-23, range: 3-41) days. Univariate analysis showed that age and clinical grade were strongly related to LoS (P<0.01). Adjusted multivariate analysis showed that the longer LoS was associated with those aged ≥ 45 (Hazard ratio (HR): 0.74, 95% confidence interval (CI): 0.60-0.91), admission to provincial hospital (HR: 0.73, 95% CI: 0.54-0.99), and severe illness (HR: 0.66, 95% CI: 0.48-0.90). By contrast, the shorter LoS was linked with residential areas with more than 5.5 healthcare workers per 1,000 population (HR: 1.32, 95% CI: 1.05-1.65). Neither gender factor nor time interval from illness onset to diagnosis showed significant impact on LoS. CONCLUSIONS: Understanding COVID-19 patients' hospital LoS and its risk factors is critical for governments' efficient allocation of resources in respective regions. In areas with older and more vulnerable population and in want of primary medical resources, early reserving and strengthening of the construction of multi-level medical institutions are strongly suggested to cope with COVID-19 outbreaks.

The Influencing Factors of Sleep Quality Among Chinese Junior and Senior High School Adolescents During the COVID-19 Pandemic.

BACKGROUND: Since coronavirus disease 2019 (COVID-19) outbreak, its terrible infectiousness has caused great panic, anxiety and poor sleep quality to the vulnerable adolescent populations. METHODS: This cross-sectional online survey recruited 10 569 Chinese junior and senior high school adolescents during 31 January to 9 February 2020. Basic socio-demographic information, Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale (SAS) and Fear of negative evaluation (FNE) were included in the survey. The χ2 and logistic regression analyses were used to identify factors correlated with poor sleep quality. RESULTS: The prevalence of poor sleep quality was 18.6% in the Chinese adolescent population. The average score of PSQI was 3.39 (SD = 2.64), which was significantly correlated with scores for anxiety (r = 0.50, p < 0.01), and FNE (r = 0.36, p < 0.01). Adjusted logistic regression indicated that gender (females) and education (senior high school) were associated with poor sleep quality, while living in Hubei Province and time spent on the COVID-19 information were inversely associated with poor sleep quality. Having a family member or friend infected/suspected and spending time on electronics were associated with higher odds of having poor sleep quality. Adolescents with anxiety were 8 times, and those with FNE were three times more likely than ones without anxiety or FNE to have poor sleep quality. In addition, the number of meals, exercise time and diet quality were also significantly associated with sleep quality. (p < 0.05). CONCLUSIONS: Poor sleep quality was common during the COVID-19 pandemic in Chinese adolescents. Understanding several factors associated with the poor sleep quality will offer some important insights into determining potential interventions to improve sleep quality during the COVID-19 pandemic.

Willingness and SARS-CoV-2 Vaccination Coverage among Healthcare Workers in China: A Nationwide Study.

Background: The SARS-CoV-2 vaccine has been widely rolled out globally in the general populations. However, specific data on vaccination confidence, willingness or coverage among health care workers (HCWs) has been less reported. Methods: A cross-sectional online survey was conducted to specify the basic data and patterns of vaccination confidence, willingness and coverage among HCWs nationwide. Results: In total, 2386 out of 2583 (92.4%) participants were enrolled for analysis, and the rates of confidence in vaccine, professional institutes and government were 75.1%, 85.2% and 85.4%, respectively. The overall vaccination coverage rate was 63.6% which was adjusted as 82.8% for participants under current medical conditions or having contraindications. Confidence in vaccine safety was shown to be the most related factor to willingness among doctors, nurses, medical technicians and hospital administrators, while confidence in vaccine effectiveness as well as trust in government played the key role in formulating public health employees' willingness. 130 (7.1% of 1833) participants reporting willingness still not been vaccinated regardless of contraindications. Multivariate analysis among willingness participants showed that males, aged over 30 years, public health employees and higher vaccination confidence had significantly higher vaccination rates with ORs (95% confidence intervals) as 1.64 (1.08-2.49), 3.14 (2.14-4.62), 2.43 (1.46-4.04) or 2.31 (1.24-4.33). Conclusions: HCWs' confidence, willingness and coverage rates to the vaccine were generally at high levels. Heterogeneity among HCWs should be considered for future vaccination promotion strategies. The population's confidence in vaccination is not only the determinant to their willingness, but also guarantees their actual vaccine uptake.

The association between BMI and metabolically unhealthy status with COVID-19 mortality: Based on 3019 inpatients from Wuhan, China.

BACKGROUND AND AIMS: Patients with multiple metabolic diseases are at high risk for the occurrence and death of COVID-19. Little is known about patients with underweight and metabolically healthy obesity. The aim of this study is to evaluate the impact of BMI and COVID-19 mortality in hospitalized patients, and also explore the association in different metabolically healthy (MHS) and unhealthy status (MUS). METHODS AND RESULTS: A retrospective cohort study based on 3019 inpatients from Wuhan was conducted. Included patients were classified into four groups according the BMI level (underweight, normal weight, overweight and obesity), and patients with at least one of the metabolic abnormalities (diabetes, hypertension, dyslipidemia) was defined as MUS. Multiple Cox model was used to calculate the hazard ratio (HR). Compared to patients with normal weight, the HRs of overweight and obesity for COVID-19 mortality were 1.91 (95%CI:1.02-3.58) and 2.54 (95%CI:1.22-5.25) respectively in total patients, and 2.58 (95%CI:1.16-5.75) and 3.89 (95%CI:1.62-9.32) respectively in the elderly. The HR of underweight for COVID-19 mortality was 4.58 (95%CI:1.56-13.48) in the elderly. For different metabolic statuses, both underweight, overweight and obesity had obviously negative association with COVID-19 mortality in total and elderly patients with MUS. However, no significance was found in non-elderly and patients with MHS. CONCLUSION: Not only overweight or obesity, but also underweight can be associated with COVID-9 mortality, especially in the elderly and in patients with MUS. More large-scale studies are needed for patients with underweight and metabolically healthy overweight or obesity.

Prevalence of mental health problems and associated factors among front-line public health workers during the COVID-19 pandemic in China: an effort-reward imbalance model-informed study.

BACKGROUND: Poor mental health status and associated risk factors of public health workers have been overlooked during the COVID-19 pandemic. This study used the effort-reward imbalance model to investigate the association between work-stress characteristics (effort, over-commitment, reward) and mental health problems (anxiety and depression) among front-line public health workers during the COVID-19 pandemic in China. METHODS: A total of 4850 valid online questionnaires were collected through a self- constructed sociodemographic questionnaire, the adapted ERI questionnaire, the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item General Anxiety Disorder Scale (GAD-7). Hierarchical logistic regression analysis was conducted to investigate the association between ERI factors and mental health problems (i.e., depression and anxiety), with reward treated as a potential moderator in such associations. RESULTS: The data showed that effort and over-commitment were positively associated with depression and anxiety, while reward was negatively associated with depression and anxiety. Development and job acceptance were the two dimensions of reward buffered the harmful effect of effort/over-commitment on depression and anxiety, whereas esteem was non-significant. CONCLUSIONS: This study confirmed the harmful effects of effort and over-commitment on mental health among public health workers during the COVID-19 pandemic in China. Such effects could be alleviated through an appropriate reward system, especially the development and job acceptance dimensions of such a system. These findings highlight the importance of establishing an emergency reward system, comprising reasonable work-allocation mechanism, bonuses and honorary titles, a continuous education system and better career-development opportunities.

Working conditions and health status of 6,317 front line public health workers across five provinces in China during the COVID-19 epidemic: a cross-sectional study.

BACKGROUND: Public health workers at the Chinese Centre for Disease Control and Prevention (China CDC) and primary health care institutes (PHIs) were among the main workers who implemented prevention, control, and containment measures. However, their efforts and health status have not been well documented. We aimed to investigate the working conditions and health status of front line public health workers in China during the COVID-19 epidemic. METHODS: Between 18 February and 1 March 2020, we conducted an online cross-sectional survey of 2,313 CDC workers and 4,004 PHI workers in five provinces across China experiencing different scales of COVID-19 epidemic. We surveyed all participants about their work conditions, roles, burdens, perceptions, mental health, and self-rated health using a self-constructed questionnaire and standardised measurements (i.e., Patient Health Questionnaire and General Anxiety Disorder scale). To examine the independent associations between working conditions and health outcomes, we used multivariate regression models controlling for potential confounders. RESULTS: The prevalence of depression, anxiety, and poor self-rated health was 21.3, 19.0, and 9.8%, respectively, among public health workers (27.1, 20.6, and 15.0% among CDC workers and 17.5, 17.9, and 6.8% among PHI workers). The majority (71.6%) made immense efforts in both field and non-field work. Nearly 20.0% have worked all night for more than 3 days, and 45.3% had worked throughout the Chinese New Year holiday. Three risk factors and two protective factors were found to be independently associated with all three health outcomes in our final multivariate models: working all night for >3 days (multivariate odds ratio [ORm]=1.67~1.75, p<0.001), concerns about infection at work (ORm=1.46~1.89, p<0.001), perceived troubles at work (ORm=1.10~1.28, p<0.001), initiating COVID-19 prevention work after January 23 (ORm=0.78~0.82, p=0.002~0.008), and ability to persist for > 1 month at the current work intensity (ORm=0.44~0.55, p<0.001). CONCLUSIONS: Chinese public health workers made immense efforts and personal sacrifices to control the COVID-19 epidemic and faced the risk of mental health problems. Efforts are needed to improve the working conditions and health status of public health workers and thus maintain their morale and effectiveness during the fight against COVID-19.

Risk factors associated with the progression of COVID-19 in elderly diabetes patients.

AIM: To describe the clinical characteristics and risk factors associated with the progression of COVID-19 in elderly diabetes patients. METHODS: This was a retrospective cohort study, including elderly COVID-19 patients admitted to Wuhan Huoshenshan Hospital between February 10 and 13, 2020. Demographic data, medical history, signs and symptoms, and laboratory parameters were collected and analysed. RESULTS: We included 131 elderly COVID-19 patients (50 patients with diabetes). COVID-19 diabetes patients experienced more severe pneumonia and abnormal organ functions than non-diabetes patients (P < 0.05 or P < 0.01). Most function indicators were significantly different between the mild to moderate and severely ill groups in diabetes patients (P < 0.05 or P < 0.01). Python analysis confirmed diabetes was the independent risk factor of COVID-19 progression in elderly patients. All blood glucose (BG) indices went into the risk factor equation. The cut-off values of COVID-19 progression were BG value on admission > 8.0 mmol/L or maximum BG value > 12.0 mmol/L in all elderly patients, and BG value on admission > 5.1 mmol/L or maximum BG value > 5.4 mmol/L in non-diabetes patients. CONCLUSIONS: Diabetes is an independent important risk factor, and glucose levels associate closely with COVID-19 progression in elderly patients.

Should we remain hopeful? The key 8 weeks: spatiotemporal epidemic characteristics of COVID-19 in Sichuan Province and its comparative analysis with other provinces in China and global epidemic trends.

BACKGROUND: The COVID-19 spread worldwide quickly. Exploring the epidemiological characteristics could provide a basis for responding to imported cases abroad and to formulate prevention and control strategies in areas where COVID-19 is still spreading rapidly. METHODS: The number of confirmed cases, daily growth, incidence and length of time from the first reported case to the end of the local cases (i.e., non-overseas imported cases) were compared by spatial (geographical) and temporal classification and visualization of the development and changes of the epidemic situation by layers through maps. RESULTS: In the first wave, a total of 539 cases were reported in Sichuan, with an incidence rate of 0.6462/100,000. The closer to Hubei the population centres were, the more pronounced the epidemic was. The peak in Sichuan Province occurred in the second week. Eight weeks after the Wuhan lockdown, the health crisis had eased. The longest epidemic length at the city level in China (except Wuhan, Taiwan, and Hong Kong) was 53 days, with a median of 23 days. Spatial autocorrelation analysis of China showed positive spatial correlation (Moran's Index > 0, p < 0.05). Most countries outside China began to experience a rapid rise in infection rates 4 weeks after their first case. Some European countries experienced that rise earlier than the USA. The pandemic in Germany, Spain, Italy, and China took 28, 29, 34, and 18 days, respectively, to reach the peak of daily infections, after their daily increase of up to 20 cases. During this time, countries in the African region and Southeast Asian region were at an early stage of infections, those in the Eastern Mediterranean region and region of the Americas were in a rapid growth phase. CONCLUSIONS: After the closure of the outbreak city, appropriate isolation and control measures in the next 8 weeks were key to control the outbreak, which reduced the peak value and length of the outbreak. Some countries with improved epidemic situations need to develop a continuous "local strategy at entry checkpoints" to to fend off imported COVID-19.
