ABSTRACT
Background: Hypertensive heart disease (HHD) is a major global public health issue resulting from hypertension-induced end-organ damage. The aim of this study was to examine the global impact, risk factors, and age-period-cohort (APC) model of HHD from 1990 to 2019. Methods: Data from the 2019 Global Burden of Disease were used to assess age-adjusted HHD prevalence, disability-adjusted life years (DALYs), mortality rates, and contributions of HHD risk factors with 95% uncertainty intervals (UIs). APC models were used to analyze global age, period, and cohort mortality trends for HHD. Results: In 2019, 18.6 million prevalent HHD cases led to 1.16 million fatalities and 21.51 million DALYs. Age-adjusted rates were 233.8 (95%UI = 170.5-312.9) per 100,000 individuals for prevalence, 15.2 (11.2-16.7) for mortality, and 268.2 (204.6-298.1) for DALYs. Regionally, the Cook Islands (703.1), Jordan (561.6), and Kuwait (514.9) had the highest age-standardized incidence of HHD in 2019. There were significant increases in HHD prevalence in Andean Latin America (16.7%), western sub-Saharan Africa (5.6%), and eastern sub-Saharan Africa (4.6%). Mortality rate varied widely among countries. Risk factors like elevated systolic blood pressure and high body mass index significant influenced DALY rates, especially in females. The APC model revealed an association between mortality rates and age, with a decreasing mortality risk over time and improved survival rates for a later birth cohort. Conclusions: Despite the reduction in prevalence, HHD remains a significant public health issue, particularly in nations with low sociodemographic indices. To alleviate the impact of HHD, prevention efforts should concentrate on the management of hypertension, weight loss, and lifestyle improvement.
ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) novel severe acute respiratory syndrome affected the world population with an infectious condition for which therapeutic forms are limited and vascular sequelae are major challenges. Pregnant women are physiologically immunocompromised and can be more affected by the pandemic than the general population. Extra precaution measures against COVID-19 during and after the outbreak are essential to ensure the safety of the newborn. The aim of the present study was to report the cesarean birth of a female child with Klippel-Trenaunay of a mother currently infected by COVID-19. Case Description: A newborn of a 21-year-old mother with COVID-19 in the final stage of the disease was born through a cesarean section at full term. The physical examination at birth revealed substantial edema of the left lower limb associated with port-wine stains on the limb and left torso. The ultrasound revealed venous-lymphatic malformation affecting the entire left lower limb, suprapubic region and ipsilateral abdominal region. Two evaluations for COVID-19 were performed and both were negative. Infants of mothers with active COVID-19 infection during the birth period have a low probability of being positive for the disease, but precautions should be taken. Conclusions: The association with malformations, such as the rare Klippel-Trenaunay syndrome (KTS), constitutes another challenge regarding the diagnosis and proper conduct to be taken with these children.
ABSTRACT
Context: Coronavirus disease 2019 (COVID-19) has been revealed as a severe illness with a wide-ranging cardiac manifestation and has a worldwide burden on the health-care system. Aims: Our aim in this study is to assess the impact of mild COVID-19 infection on cardiac function in patients without previous structural heart disease. Settings and Design: We evaluated 100 outpatients with a history of mild COVID-19 infection without needing hospitalization within 3 weeks to 3 months after recovery from the acute phase of the illness between August 2020 and July 2021. Subjects and Methods: The patients were compared with 105 healthy participants without a history of COVID-19 as the control group. All participants underwent comprehensive transthoracic echocardiography. Statistical Analysis Used: Data were analyzed using IBM SPSS statistics 23. For all tests, P < 0.05 was defined as statistically significant. Results: COVID-19 patients had higher global longitudinal strain (P = 0.001), systolic pulmonary artery pressure (P = 0.008), RV E' (P = 0.049), and RV A' (P = 0.003), while had lower septal tissue velocities (P = 0.01) and left ventricular ejection fraction (EF) (LVEF) (P = 0.03). Abnormal EF (LVEF <55%) was noted in 19% of the COVID-19 patients and 8.6% of the control group (P = 0.03). Moderate or more diastolic dysfunction was noted in 10 COVID-19 patients but only in one participant in the control group (P = 0.005). Conclusions: Mild COVID-19 infection can result in cardiac functional and structural changes, even in patients without known previous structural heart disease. Echocardiography can be a useful modality for risk assessment and follow-up in patients with COVID-19.
ABSTRACT
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for coronavirus disease 2019 (COVID-19). Patients with COVID-19 manifested symptoms mainly related to the respiratory system, but also the musculoskeletal system can be involved. COVID-19 has been described as a possible cause of knee osteonecrosis (ON). A systematic review was performed to investigate the hypothetical correlation between COVID-19 and knee ON. Methods: Inclusion criteria were all articles reporting cases of knee ON after a diagnosis of SARS-CoV-2 infection. Considering that COVID-19 is an emerging disease, all levels of evidence studies were included. Results: Finally, two case series and three case reports were included. We extracted data regarding demographic and clinical characteristics, details of magnetic resonance imaging (MRI), use of corticosteroids (CCS), temporal correlation between ON and COVID-19, treatment of the lesion and its outcomes. A total of seven cases of post-COVID knee ON have been described. Knee pain arose on average 11 weeks after the diagnosis of COVID-19. All patients had knee MRI showing ON. CCS were used to treat COVID-19-related symptoms in four cases. Conservative treatment was successful in five patients. Conclusions: The correlation between COVID-19 and ON remains unclear. Probably post-COVID-19 ON has a multifactorial origin in which factors related to the patient, consequences of COVID-19 and CCS therapy add up to cause a reduction of blood supply and bone vitality until ON is triggered. A greater number of patients is needed to clarify the role of COVID-19 in the etiopathogenesis of knee ON.
ABSTRACT
Background: The COVID-19 pandemic had a profound global impact, affecting individuals, including those with mental illness, through early and widespread information dissemination. Although the neurobiological basis of delusions remains unclear, external stimuli and historical events are known to influence them. The pandemic provided a unique opportunity to explore this phenomenon. Aim: To determine the prevalence of COVID-19-related delusional content, among individuals presenting for treatment of psychosis during the peak of the COVID-19 pandemic and investigate associated clinical and demographic factors. Setting: Chris Hani Baragwanath Academic Hospital in-patient psychiatry department. Methods: Data were extracted retrospectively from adult psychiatric admissions spanning April to September 2020 on patients whose presenting complaints included delusions. Demographic factors, symptoms, psychiatric, medical and substance use history, and a documented Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis by the attending psychiatrist were collected. Results: The prevalence of COVID-19-related delusional content was 25.5%. Significant demographic association was observed with education level of Grade 12 and above (p = 0.000338). The odds of a diagnosis of schizophrenia and related disorders were 2.72 times greater than mood and psychotic disorder due to another medical condition in those with COVID- 19-related delusional content (OR 2.19, 95% CI: [1.4-3.4]). Conclusion: The presence of COVID-19-related delusional content in patients admitted to hospital with psychosis provides further evidence of the role of external stimuli in the formation of delusions. Contribution: This study underscores the influence of socio-cultural factors on delusions and advocates for interventions and expanded research to address mental health outcomes.
ABSTRACT
BACKGROUND: Since April 2022, the SARS-CoV-2 Omicron variant has caused a notable increase in pediatric COVID-19 cases in Taiwan. During the acute phase of infection, some children required admissions to pediatric intensive care units (PICU). This study aimed to analyze their clinical presentations and outcomes while exploring associated factors. METHODS: Medical records were retrospectively collected from patients with COVID-19 (aged <18 years) admitted to our PICU from April 2022-March 2023. Early stage is defined as the period without adequate vaccination and treatment guidelines for children from April-June 2022, and the remaining months are referred to as late stage. Clinical characteristics and outcomes were compared between patients in early and late stages. RESULTS: We enrolled 78 children with COVID-19, with a median length of stay (LOS) in PICU of 3 days and a 5% mortality rate. Patients admitted during the early stage had lower vaccination rates (7% vs. 50%), higher pediatric logistic organ dysfunction scores (2 vs. 0.1), and longer LOS in the PICU (6 vs. 2 days) than those admitted during the late stage. Multivariate analysis identified admission during the early stage as a risk factor for prolonged LOS (>7 days) in the PICU (odds ratio: 3.65, p = 0.047). CONCLUSION: Without available vaccinations and suitable treatment guidelines, children with COVID-19 tended to have more severe illness and prolonged LOS in the PICU. These observations highlight the importance of vaccinations and familiarity of medical providers with adequate management of this newly-emerging infectious disease.
ABSTRACT
Multisystem inflammatory syndrome in children (MIS-C) is a severe complication of SARS-CoV-2 infections in children. This syndrome manifests about a month after the initial viral infection and is characterized by fever, multiorgan dysfunction, and systemic inflammation. This chapter will review the emergence, epidemiology, clinical characteristics, diagnosis, pathophysiology, immunomodulatory treatment, prognosis, outcomes, and prevention of MIS-C. While the pathophysiology of MIS-C remains to be defined, it is a post-infection, hyperinflammatory syndrome of childhood with elevated inflammatory cytokines.

The coronavirus disease-2019 (COVID-19) pandemic has impaired the quality of life (QoL) for many due to its extensive impacts. However, few studies have addressed the specific impact of COVID-19 on the mental health of adolescents, particularly post-traumatic stress disorder (PTSD). This study considered the impact of COVID-19-related PTSD on the QoL of adolescents in China, the mediating effects of insomnia, and the moderating effects of resilience. Participants included 50,666 adolescents aged 12-18 years selected using a comprehensive sampling method. We performed data collection from January 8th to January 18th, 2023, using the Children's Revised Impact of Event Scale, Pittsburgh Sleep Quality Index, Ten-item Connor-Davidson Resilience Scale, and Screening for and Promotion of Health-related QoL in Children and Adolescents Questionnaire for data collection. Male adolescents exhibited significantly lower levels of PTSD and insomnia compared to females and scored significantly higher in psychological resilience and overall QoL. Insomnia played a mediating role between PTSD and QoL. Psychological resilience moderated the impact of COVID-19-related stress on adolescents' QoL through its influence on insomnia. PTSD resulting from the COVID-19 pandemic affects the QoL of adolescents through the presence of insomnia. Psychological resilience plays a moderating role in this process. Cultivating psychological resilience in adolescents can effectively enhance their ability to cope with the impacts of sudden public events.

BACKGROUND: Considering the challenges of the referral system in the family physician program and the impact of COVID-19 pandemic on the performance of the relevant ministry's programs, it is necessary to assess the performance of the referral system. This study was conducted with the aim of investigating the performance of the family physician referral system before and during COVID-19 in Golestan province. METHODS: The present repeated cross-sectional study was conducted on secondary data Recorded of 786,603 cases referred and cared by family physicians (including information on physicians' and midwives' visits, percentage of prescriptions and other information) in Golestan province from 2017 to 2022 in a census and retrospective manner. Data were collected using the reference ratio checklist and analyzed with SPSS 23 software at a significance level of less than 0.05. RESULTS: Referral to 10 types of medical specialties and 10 indicators of family physicians referral before and during COVID-19 were investigated. The highest and lowest percentages of referrals by family physicians were belonged to the surgical (17.6%) and infectious (2%) specialists before COVID-19, and internal medicine (15.07%) and urology (3%) specialists during COVID-19, respectively. Referral due to physician's diagnosis increased by 19.3% compared to before Covid-19, target group increased by 0.86%, care decreased by 2.69% and reverse referral decreased by 36.1%. The amount of population covered by rural insurance, the amount of visits to midwives, the percentage of electronic appointments in the post-Covid-19 years have changed significantly compared to before.it (P-Value < 0.05). CONCLUSION: The present study showed that the COVID-19 pandemic had a significant impact on family physician referral indicators, such as the process of referral to specialists, drug prescriptions, insurance coverage, one-time service population, and patient care, which can be used to eliminate the weaknesses and Strengthening the strengths of the programs being implemented in the face of possible pandemics is very useful and effective and can be used in the country. Finally, the results obtained from this research provide evidence to discuss the importance of the family physicians care and referral system in the face of special conditions for quality control in health policies.

Background: Globally, diet low in milk is the third greatest risk factor for colorectal cancer (CRC). However, there has been a lack of detailed worldwide analysis of the burden and trends of CRC attributable to diet low in milk. Objective: We aim to assess the spatiotemporal trends of CRC-related mortality and disability-adjusted life-years (DALYs) attributable to diet low in milk at the global, regional, and national levels from 1990 to 2019. Methods: Data of mortality, DALYs, age-standardized mortality rate (ASMR), and age-standardized DALY rate (ASDR) of CRC attributable to diet low in milk were extracted from the Global Burden of Disease (GBD) 2019 study. The burden of CRC attributable to diet low in milk was estimated using the ASMR and ASDR, while accounting for sex, age, country, and socio-demographic index (SDI). From 1990 to 2019, the estimated annual percentage change (EAPC) was calculated to clarify the temporal trends in the ASMR and ASDR attributable to diet low in milk. Results: In 2019, there were 166,456 (95% UI = 107,221-226,027) deaths and 3,799,297 (95% UI = 2,457,768-5,124,453) DALYs attributable to diet low in milk, accounting for 15.3 and 15.6% of CRC-related deaths and DALYs in 2019. CRC-related deaths and DALYs attributed to diet low in milk increased by 130.5 and 115.4%, from 1990 to 2019. The burden of CRC attributable to diet low in milk varied notably among regions and nations. High-middle SDI regions had the highest ASDR and ASMR of CRC linked to diet low in milk, while there was a slight downward trend high SDI regions. Among geographical regions, East Asia had the highest number of CRC-related deaths and DALYs attributable to diet low in milk. Notably, the burden of CRC was highest in males and the elderly. With coefficients of -0.36 and -0.36, the EAPC in ASMR and ASDR was significantly inversely correlated with the Human Development Index in 2019. Conclusion: Globally, the number of CRC deaths attributable to diet low in milk has continued to increase over the last 30 years. Therefore, government and authorities should conduct education campaigns to encourage individuals to increase daily milk intake.
ABSTRACT
BACKGROUND: The impact of chronic oral anticoagulant (OACs) use on long-term post-discharge outcomes after coronavirus disease 2019 (COVID-19) hospitalisation remains unclear. Herein, we compared clinical outcomes up to 2-years after COVID-19 hospitalisation between patients on vitamin K antagonists (VKAs), direct-acting OACs (DOACs) and no OAC therapy. METHODS: Data from TriNetX, a global federated health research network, were used. Adult patients on VKAs, DOACs or no OAC therapy at diagnosis of COVID-19 between 20 January 2020 and 31 December 2021, who were hospitalised for COVID-19, were included. The primary outcomes were all-cause mortality, ischaemic stroke/transient ischaemic attack (TIA)/systemic embolism (SE) and the composite of intracranial haemorrhage (ICH)/gastrointestinal bleeding, at 2 years after COVID-19 hospitalisation. RESULTS: We included 110,834 patients with COVID-19. Following propensity score matching (PSM), we identified a decreased mortality risk in DOAC-treated patients compared to the no OAC cohort (RR .808, 95% CI .751-.870). A higher risk of ischaemic stroke/TIA/SE was observed in VKA users compared to DOAC users (RR 1.100, 95% CI 1.020-1.220) and in VKA users compared to patients not taking OAC (RR 1.400, 95% CI 1.140-1.720). VKA use was associated with a greater risk of ICH/gastrointestinal bleeding than DOAC users (RR 1.198, 95% CI 1.066-1.347), while DOAC users had a lower risk compared to no OAC-treated patients (RR .840, 95% CI .754-.936). CONCLUSION: COVID-19 patients taking prior DOACs were associated with lower long-term mortality risk and ICH/gastrointestinal bleeding than patients not taking OAC. Compared to patients on DOACs, VKA users were associated with higher risks of mortality, ischaemic stroke/TIA/SE and ICH/gastrointestinal bleeding.
ABSTRACT
PURPOSE: We aimed to determine the incidence of TB among immigrants and non-immigrants in Sanliurfa, Türkiye between 2018 and 2022 and to examine the effect of COVID-19 on the incidence, location, and drug resistance patterns of tuberculosis. METHODS: This study was a retrospective review of patients diagnosed with tuberculosis in Sanliurfa Tuberculosis Dispensary between January-2018 and May-2022. Patients were assessed in terms of age, sex, site of tuberculosis, and drug resistance profiles before and during the COVID-19 pandemic. RESULTS: A total of 887 patients with TB were included in the study. The mean age of patients diagnosed with tuberculosis was 40.63 ± 17.50 years. Of the total number of patients diagnosed, 50.7% were women, 85.8% were Turkish citizens, and 91.9% were new cases. Comparing the rate of positive cultures between the pre-COVID-19 and COVID-19 periods revealed a statistically significant rate of positive culture during the COVID-19 period (p < 0.001). In terms of mortality, the mean age of the patients who died was 60.2 ± 18.4 years and that of the survivors was 39.1 ± 16.6 years; these values were statistically significant (p < 0.001). Among the patients who survived, the rate of pulmonary tuberculosis was statistically significantly higher than that of extrapulmonary tuberculosis (p < 0.001). CONCLUSION: The prevalence of pulmonary TB is high and the proportion of women is increasing. During the COVID-19 period, the number of patients diagnosed with TB decreased, but interestingly, the rate of positive cultures remained high, and the rate of resistance to INH also decreased. The results revealed rates similar to those reported by the World Health Organization.
ABSTRACT
The coronavirus disease 2019 pandemic created unprecedented challenges for healthcare systems around the world. Healthcare assistants played a vital role in the provision of frontline patient care during this crisis. Despite their important contribution, there exists limited research that specifically examines the healthcare assistant's experiences and perspectives of care provision during the COVID-19 pandemic. This study explored healthcare assistants' caring experiences and perspectives on resilience and self-efficacy during the COVID-19 pandemic in Hong Kong. A qualitative descriptive study with semi-structured interviews was conducted with 25 healthcare assistants from public hospitals. Interview recordings were analyzed using thematic analysis. Five main themes emerged from the data: frontline reinforcement: supporting HCAs through resourcing and education amidst the COVID-19 crisis, confronting uncertainty: building personal fortitude in the face of the COVID-19 pandemic, fostering collective resilience through shared support, self-efficacy as a catalyst for adaptive growth, and paving the way for transformation. These findings advocate for the resilience and self-efficacy of healthcare assistants; this may potentially strengthen healthcare system preparedness for navigating unpredictable challenges in the future.
ABSTRACT
This study investigated the correlation between oxidative stress and blood amino acids associated with nitric oxide metabolism in adult patients with coronavirus disease (COVID-19) pneumonia. Clinical data and serum samples were prospectively collected from 100 adult patients hospitalized for COVID-19 between July 2020 and August 2021. Patients with COVID-19 were categorized into three groups for analysis based on lung infiltrates, oxygen inhalation upon admission, and the initiation of oxygen therapy after admission. Blood data, oxidative stress-related biomarkers, and serum amino acid levels upon admission were compared in these groups. Patients with lung infiltrations requiring oxygen therapy upon admission or starting oxygen post-admission exhibited higher serum levels of hydroperoxides and lower levels of citrulline compared to the control group. No remarkable differences were observed in nitrite/nitrate, asymmetric dimethylarginine, and arginine levels. Serum citrulline levels correlated significantly with serum lactate dehydrogenase and C-reactive protein levels. A significant negative correlation was found between serum levels of citrulline and hydroperoxides. Levels of hydroperoxides decreased, and citrulline levels increased during the recovery period compared to admission. Patients with COVID-19 with extensive pneumonia or poor oxygenation showed increased oxidative stress and reduced citrulline levels in the blood compared to those with fewer pulmonary complications. These findings suggest that combined oxidative stress and abnormal citrulline metabolism may play a role in the pathogenesis of COVID-19 pneumonia.

BACKGROUND: Liver cancer (LC) remains a major cause of cancer death worldwide. Grasping prevalence trends is key to informing strategies for control and prevention. We analyzed the global, regional and national trends in LC prevalence and its major causes from 1990 to 2019. METHODS: We obtained LC age-standardized prevalence rate (ASPR) estimates from the Global Burden of Disease study 2019 and assessed trends using Joinpoint regression. LC cases were categorized into those due to hepatitis B virus (HBV), hepatitis C virus (HCV), alcohol use, nonalcoholic steatohepatitis (NASH) and other causes. RESULTS: While the ASPR of LC has shown a global decrease, there are specific regions where an increase in ASPR has been observed, with the highest rates in America. HBV remained the leading cause of LC (41.45%) but significant increases occurred for HCV, alcohol use and NASH. Prevalence correlated with socioeconomic development. High-income countries had higher LC rates from HCV and alcohol but lower HBV-related LC. In high-income nations, LC prevalence climbs; the converse holds in middle- and low-income countries. CONCLUSIONS: Despite a global ASPR decrease, LC due to HCV, NASH, and alcohol is rising. Prevention strategies must prioritize HBV vaccination, HCV treatment, and alcohol regulation. IMPACT: The study informs targeted LC control policies and emphasizes the importance of continued monitoring and regional cooperation to combat LC.
ABSTRACT
Pneumocystis jirovecii pneumonia is an opportunistic infection that affects HIV-infected and immunocompromised persons and rarely affects immunocompetent patients. However, after the advent of the COVID-19 pandemic, some COVID-19 patients without immunocompromise or HIV were infected with P. jirovecii. Clinical manifestations were atypical, easily misdiagnosed, and rapidly progressive, and the prognosis was poor.

Background: Over the years, Indian regulations have undergone numerous amendments, including stringent reporting deadlines, relatedness requirements, and compensation obligations for serious adverse event (SAE). A historic change, new drugs and trial rules-2019, was proposed on March 19, 2019. The purpose of the study was to ascertain whether various stakeholders were reporting in accordance with the evolving SAE criteria. Materials and Methods: Data were retrieved after the Ethics Committee's approval between August 2014 and December 2021. Data gathered before March 19, 2019, were categorized as "BEFORE" data, while the remaining data were categorized as "AFTER." Utilizing causality, on-site SAE reporting, and the ethics committee review procedure, we evaluated the compliance. The data were evaluated using descriptive statistics, and the Chi-square or Mann-Whitney tests were used to compare the "BEFORE" and "AFTER" groups. Results: A total of 77 SAEs were reported in 26 clinical trials, where most clinical trials were phase III. Endocrine projects made up 9/26 (34.61%). In the cardiology studies, the greatest SAE distribution was 21 SAEs/89 participants (23.59%) with approximately 48% of these being vascular. The "AFTER" group noticed a decrease in the total number and length of SAE subcommittee meetings. In the "AFTER" group, there was a significantly higher median number of agenda items/meetings (8 [4.5-10.75]) (P < 0.0001). The median interval between the onset of SAE and the first reporting date, however, was just 1 day (interquartile range: 1-5 days). In nondeath SAEs, there was no significant difference in the compensation paid. In the "AFTER" group, there were no discrepancies in reporting SAE. Conclusion: There is acceptable adherence to SAE reporting criteria.
ABSTRACT
Globally, hepatitis C virus (HCV) and coronavirus disease 2019 (COVID-19) are the most common causes of death due to the lack of early predictive and diagnostic tools. Therefore, research for a new biomarker is crucial. Inflammatory biomarkers are critical central players in the pathogenesis of viral infections. IL-18, produced by macrophages in early viral infections, triggers inflammatory biomarkers and interferon production, crucial for viral host defense. Finding out IL-18 function can help understand COVID-19 pathophysiology and predict disease prognosis. Histamine and its receptors regulate allergic lung responses, with H1 receptor inhibition potentially reducing inflammation in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. angiotensin-converting enzyme 2 (ACE-2) receptors on cholangiocytes suggest liver involvement in SARS-CoV-2 infection. The current study presents the potential impact of circulating acetylcholine, histamine, IL-18, and interferon-Alpha as diagnostic tools in HCV, COVID-19, and dual HCV-COVID-19 pathogenesis. The current study was a prospective cross-section conducted on 188 participants classified into the following four groups: Group 1 COVID-19 (n = 47), Group 2 HCV (n = 47), and Group 3 HCV-COVID-19 patients (n = 47), besides the healthy control Group 4 (n = 47). The levels of acetylcholine, histamine, IL-18, and interferon-alpha were assayed using the ELISA method. Liver and kidney functions within all groups showed a marked alteration compared to the healthy control group. Our statistical analysis found that individuals with dual infection with HCV-COVID-19 had high ferritin levels compared to other biomarkers while those with COVID-19 infection had high levels of D-Dimer. The histamine, acetylcholine, and IL-18 biomarkers in both COVID-19 and dual HCV-COVID-19 groups have shown discriminatory power, making them potential diagnostic tests for infection. These three biomarkers showed satisfactory performance in identifying HCV infection. The IFN-Alpha test performed well in the HCV-COVID-19 group and was fair in the COVID-19 group, but it had little discriminative value in the HCV group. Moreover, our findings highlighted the pivotal role of acetylcholine, histamine, IL-18, and interferon-Alpha in HCV, COVID-19, and dual HCV-COVID-19 infection. Circulating levels of acetylcholine, histamine, IL-18, and interferon-Alpha can be potential early indicators for HCV, COVID-19, and dual HCV-COVID-19 infection. We acknowledge that further large multicenter experimental studies are needed to further investigate the role biomarkers play in influencing the likelihood of infection to confirm and extend our observations and to better understand and ultimately prevent or treat these diseases.

On December 7, 2022, China switched from dynamic zeroing strategy against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to reopening. A nationwide SARS-CoV-2 epidemic emerged rapidly. The effect of smoking on SARS-CoV-2 infection remains unclear. We aimed to retrospectively investigate the relationship between smoking and coronavirus disease 2019 (COVID-19) using a community-based cohort of smokers and non-smokers. We included participants from a pre-pandemic cohort with a prolonged follow-up period. Data on smoking status, body mass index, and history of other diseases were collected from health examination and consultation clinic records. Cox regression analysis was used to identify the relationship between groups and SARS-CoV-2 infection over time. We analysed 218 male patients with varied smoking statuses (46.3% current or ex-smokers; average age 68.63 ± 9.81 years). Two peaks in the epidemic were observed following the December 2022 outbreak. At the end of the second peak, non-smokers, current smokers, and ex-smokers had primary infection rates increase to 88.0%, 65.1%, and 81.0%, respectively, with a significant difference between the groups. Current smoking significantly protected against SARS-CoV-2 infection (HR 0.625, 95% CI 0.402-0.970, p = 0.036). Further analyses showed that the prevalence of pneumonia in the unvaccinated, older, diabetic, and non-smoking groups was significantly higher than that in the other groups (p < 0.05). Our study suggests a potential association between smoking and a reduced risk of SARS-CoV-2 infection and pneumonia. This indicates that nicotine and ACE2 play important roles in preventing COVID-19 and its progression. We suggest smokers use nicotine replacement therapy during hospitalization for COVID-19.
