This study aimed to assess the impact of COVID-19 infection on cardiac surgery outcomes in patients who contracted COVID-19 peri-operatively or had recently recovered from COVID-19. The study prospectively enrolled 95 patients scheduled for cardiac surgery who had recently recovered from COVID-19. This formed the post-COVID-19 group. The other group consisted of 25 patients who contracted COVID-19 peri-operatively. Patients were followed for all-cause mortality as the primary endpoint and postoperative course complications as the secondary endpoint. Data were compared to a historical cohort of 280 non-COVID-19 patients. The peri-operative COVID-19 group exhibited a significantly higher prevalence of primary outcome all-cause mortality (28%), compared with 4.3% in the controls (p < 0.01), as well as the secondary composite endpoint (stroke, peri-operative myocardial infarction and pneumonia) (52 vs 13.9%, p < 0.01). The post-COVID-19 group had a higher incidence of acute pulmonary embolism (3.2 vs 0%, p < 0.01) and atrial fibrillation (23.4 vs 11.4%, p < 0.01). Patients who contracted COVID-19 peri-operatively had an increased rate of mortality and postoperative complications, while cardiac surgery in the recently recovered COVID-19 group was associated with a higher incidence of pulmonary embolism and atrial fibrillation.

Despite evidence of COVID-19's impact on healthcare workers, there is limited documentation on psychiatric nurses' perceptions and experiences working in psychiatric institutions in Gauteng Province during the pandemic. The study aimed to explore and describe psychiatric nurses' perceptions and experiences working in a psychiatric institution during the COVID-19 pandemic. A qualitative, exploratory, descriptive, and contextual design was employed to explore psychiatric nurses' perceptions and experiences working in a psychiatric institution during the COVID-19 pandemic, utilising in-depth individual interviews. Data were collected from a specialised tertiary academic psychiatric hospital in Gauteng Province, South Africa, between 23 March and 12 September 2023. Ten participants were interviewed. Colaizzi's seven-step method was used to analyse the transcribed interviews. Four themes and various sub-themes emerged from the interviews: confronting the reality and fear of COVID-19; the psychiatric nurses were not adequately prepared to care for individuals with COVID-19; COVID-19 increased their workload and experienced that it impacted their health negatively; and based on their experiences, psychiatric nurses offered valuable insights that can inform better management strategies for future pandemics in similar environments. This study reveals that South Africa's psychiatric nurses faced the COVID-19 crisis from a position of vulnerability. The findings highlight how pre-existing burdens, such as poor infrastructure, a lack of equipment, and staff shortages in the South African healthcare system, were amplified during the COVID-19 pandemic, placing pressure on psychiatric nurses.

BackgroundThis study investigates the severity of COVID-19 infection among pregnant women during three distinct waves of the pandemic in Ahvaz, Iran. Considering the serious impact of COVID-19 on maternal and neonatal health, this research aimed to compare the clinical characteristics and disease severity across these waves.MethodsThis was a retrospective observational cohort study conducted to identify the clinical features and outcomes of pregnant women with PCR-confirmed SARS-CoV-2 infection during three pandemic waves in Ahvaz. Data including demographic variables, disease severity (classified according to WHO clinical criteria), complications, and delivery outcomes were extracted from hospital medical records between February 2020 and December 2021.ResultsA total of 267 pregnant women with confirmed COVID-19 were analyzed across three pandemic waves. In the third wave, the mean maternal age was 30.58 years, mean gravida 2.61, and mean parity 1.23. The average gestational age at admission was 35.49 weeks, and mean BMI was 23.46 kg/m². The mean duration of hospitalization was 7.01 days, and average recovery time 20.09 days. Compared with earlier waves, the third wave showed a higher frequency of positive CT findings, fever, cough, and shortness of breath, indicating greater disease severity.ConclusionThe findings demonstrate changing patterns in the clinical presentation and severity of COVID-19 among pregnant women across successive pandemic waves. These differences may reflect evolving viral characteristics and public health responses. The study underscores the need for tailored maternal care strategies and ongoing surveillance to manage COVID-19 and its potential long-term effects in this vulnerable population.

The impact of the COVID-19 pandemic on pediatric obesity and comorbidities was investigated via a retrospective analysis of new patient visits at a pediatric weight management clinic. Prepandemic (N = 1590, January 1, 2017, to March 20, 2020) and postpandemic (N = 1040, April 1, 2020, to June 8, 2023), patients ages 2-21 years with overweight or obesity were studied. Results revealed significant increase in obesity severity during the postpandemic period (OR = 1.70 [1.45, 1.99]), with more comorbidities (OR = 1.28 [1.22, 1.34]). Prediabetes (OR = 1.62 [1.07, 2.47]), eating disorder/hyperphagia (OR = 1.77 [1.26, 2.50]), and attention deficit hyperactivity disorder (OR = 1.36 [1.09, 1.69]) diagnoses were more prevalent postpandemic. Patients aged 10 to <14 years (OR = 2.39 [1.51, 3.79]) and non-Hispanic patients (OR = 1.44 [1.07, 1.94]) had higher odds of mood/mental health disorder diagnoses postpandemic. In conclusion, the COVID-19 pandemic is associated with worsening pediatric obesity severity and higher prevalence of obesity-related comorbidities in new patients presenting for treatment.

Vaccines have been pivotal in reducing the incidence and severity of infectious diseases, improving population health, and lowering mortality rates globally. While substantial progress has been made in optimizing vaccine formulations, adjuvants, and schedules, comparatively less attention has been given to how the site of vaccination may influence immunologic outcomes. This review examines the impact of the administration of prime and booster vaccine doses in the same (ipsilateral) versus the opposite arms (contralateral) on vaccine immunogenicity. We review animal model and human studies evaluating the impact of ipsilateral versus contralateral COVID-19 and non-COVID-19 vaccine boosting on immunologic outcomes with a focus on the germinal center response, antibody production, and T cell activation. While some studies suggest that ipsilateral administration may enhance the quality of germinal center B cell responses and antibody magnitude, data across different studies have been inconsistent. Relatively few studies have compared ipsilateral versus contralateral boosting, and differences in study design and outcomes have limited the ability to draw conclusions as to whether one is superior to the other. This review highlights a noteworthy and underexplored area in vaccinology and the need for future research to clarify whether ipsilateral/contralateral boosting strategies matter. To answer this question, high-quality, randomized controlled trials evaluating different types of vaccines that consider immunologic mechanisms, capture key time points and appropriate specimens, and evaluate early and long-term immunogenicity endpoints are required.

Impact of COVID-19 on Parental Barriers to Childhood Vaccination: A Systematic Review.

BackgroundThe purpose of this study was to explore healthcare utilization among children with sickle cell disease (SCD) during the COVID-19 pandemic using a concurrent mixed-methods study design.Method and SampleTrends in healthcare encounters were examined across the institutional SCD population from September 2019 through February 2021. A convenience sample of children with SCD (8-17 years of age) and their parent/caregiver completed the COVID-19 Exposure and Family Impact Scale and a semistructured interview. Patients were eligible if they had a history of high hospital utilization (HHU; ≥5 admissions in 2019) or moderate HHU (MODHU; ≥2 ED visits or 2-4 admissions in 2019). Differences in outcomes by HHU status were assessed using Fisher's exact and Wilcoxon rank sum tests. Qualitative data were analyzed using thematic analysis.ResultsAcross the institutional SCD population (N = 2,153), healthcare encounters decreased in the early pandemic, returning close to baseline mid-pandemic. The sample (N = 16) was 75% (n = 12) male, 50% (n = 8) HHU, and median age 13.1 years; all parent participants were mothers. The MODHU group reported a more negative impact of COVID-19 on family functioning compared with the HHU group (p = .03), while distress was similarly high across both groups. Parents believed reduced exposure to infection, greater control over environmental triggers, and management of pain at home resulted in fewer healthcare visits. Parents described child distress as related to social isolation and virtual school.ConclusionWith reduced exposure to illness triggers, healthcare utilization for children with SCD decreased during the pandemic, although social isolation was associated with distress.

COVID-19 containment measures in Japan, characterized by intermittent states of emergency (SE) without strict lockdowns from April 2020 to September 2021, may have significantly impacted lifestyle, weight, and body composition in individuals with diabetes. This study examines changes in glycemic management, body weight, and body composition before, during, and after SE in adults with diabetes. This retrospective study included individuals with diabetes aged 20 years or older whose HbA1c and body composition were measured in three periods of pre-SE (April 2019-March 2020), SE (April 2020-September 2021), and post-SE (October 2021-September 2022). Hospitalized individuals were excluded. Participants were divided into subgroups by age (young: <65 years, older: ≥65 years) and gender for analysis. A total of 673 subjects were analyzed. No significant changes in HbA1c were observed in any period. Body weight remained constant during SE but decreased post-SE. Continuous decreases in skeletal muscle mass were noted in all groups. In the total analysis, body fat mass initially increased during SE but decreased post-SE. However, due to weight loss in the post-SE, the overall body fat percentage rose. Notably, in older males, body fat mass increased during SE and remained unchanged post-SE, resulting in a continuous increase in body fat percentage throughout observational periods. The study highlights a continuous decline in muscle mass and body weight changes, with body fat percentage fluctuations differing by age and gender. The impact was most significant in older males, underscoring the need for targeted health interventions.

Background:Allergic diseases, including asthma, allergic rhinitis (AR), and atopic dermatitis (AD), affect nearly 20% of the global population and are influenced by complex immune mechanisms. The COVID-19 pandemic, driven by SARS-CoV-2 and its evolving variants, has reshaped clinical and immunological landscapes. Previous evidence regarding the interaction between COVID-19 and allergic diseases remains inconsistent, necessitating large-scale real-world investigations.Objective:This study aimed to investigate the association between COVID-19 infection and the subsequent development of allergic diseases (AD, AR, and asthma) in pediatric populations, while exploring subgroup variations and testing robustness through sensitivity analyses.Methods:We performed a retrospective cohort study using TriNetX electronic health records from 56 U.S. healthcare facilities. Children <18 years with ≥2 visits and Polymerase chain reaction (PCR) testing (2020–2022) were included, excluding those with prior allergic disease. COVID-19 was defined by ICD-10 U07.1 and RNA positivity. Propensity score matching (1:1) balanced baseline characteristics. The primary outcome was the incident allergic disease within 1 year, assessed using Cox models; subgroup and sensitivity analyses tested robustness.Results:After matching, 412,017 patients were included in each cohort (COVID-19 vs non-COVID-19). Children with COVID-19 exhibited a significantly higher risk of developing allergic diseases (Hazard ratio (HR) = 1.211, 95% confidence interval [CI]: 1.189–1.235; P < 0.001). Elevated risks were observed across all categories: AD (HR = 1.179, 95% CI: 1.140–1.219), asthma (HR = 1.252, 95% CI: 1.216–1.290), and AR (HR = 1.223, 95% CI: 1.188–1.259). Kaplan–Meier curves demonstrated consistently higher cumulative incidence in the COVID-19 cohort. Subgroup analyses stratified by sex, age, and race yielded concordant results, while sensitivity analyses—including competing risks, extended follow-up to 2–3 years, stricter visit definitions, and exclusion of vaccinated individuals—confirmed robustness.Conclusion:COVID-19 infection was linked to a higher risk of allergic diseases in children, suggesting postviral immune dysregulation and microbiome changes as possible mechanisms. Further studies are needed to clarify causality and guide prevention and management.

Characteristics and sources of wintertime nitrous acid (HONO): Insights from year-to-year variations and the impact of COVID-19.

This paper describes how the Government of Manitoba employed a task force to support the recovery of diagnostic and surgical services from the impact of COVID-19 from December 2021 to December 2023. The paper describes how the system evolved during this period to optimise the efficiency and effectiveness of recovery efforts. The paper supports a more comprehensive implementation of the incident command system (ICS) to manage recovery effectively, with specific reference to the recovery of diagnostic and surgical services. The implementation of ICS and robust structure and processes led to the elimination of 83 per cent of the pandemic backlog and achievement of wait time targets for 26 per cent of services lines in 'expanded scope', with 83 per cent of service lines trending positively towards the target. ICS structured task forces may be an important tool in addressing specific challenges within a healthcare system.

COVID-19 Impact on Adolescent Vaccination Administration Rates in the U.S. Military Health System.

Bloodstream infections (BSIs) are associated with high morbidity and mortality. Although frequently studied in adults, data on pediatric patients remain limited. This study evaluated the epidemiology of BSIs in children from 2013 to 2023, associating antibacterial consumption with bacterial resistance, including comparisons between pre- and post-COVID-19 periods in a Brazilian teaching hospital. This retrospective cross-sectional study analyzed 15.369 blood cultures (BC) collected from patients under 18years old between January 2013 and December 2023. All positive BC were included. Blood samples were incubated using the BACTEC™ system. Species identification and antibacterial susceptibility testing were performed via the BD-Phoenix™ system. A PCR-based assay was used to detect carbapenemase-encoding genes in Gram-negative bacilli (GNB). Data analysis was performed using Microsoft® Excel®. A total of 266 isolates were recovered from 224 pediatric patients. Of these, 138 (51.9%) were Gram-positive cocci (GPC), 105 (39.5%) were GNB and 21 (7.9%) were Fungi. Infants (< 1year) represented the majority of cases (143/224; 63.8%) with GPC predominating (59.6%), especially S. epidermidis (46/166; 28%). GPCs were also predominant in adolescents (13 to < 18years; 50%). GNBs were more frequent in the 1-6 and 7-12-year groups, with Klebsiella pneumoniae being the most common (13.6% and 5.6%, respectively), including one blaNDM-positive isolate identified during the pandemic. Fungal species were detected only after 2015, with Candida genus representing over 95% of the cases. The most common fungi were Candida parapsilosis (47.6%), followed by Candida tropicalis (19.0%) and Candida albicans (19.0%), while other species such as C. lusitaneae, C. rugosa and Kodamaea ohmeri represented 14.4% of isolates. Most fungal isolates (47.6%) were from patients aged < 1year and admitted in the pediatric-intensive care unit. Antimicrobial susceptibility tests revealed increased MICs90 values in 2022-2023, particularly for meropenem and ceftriaxone coinciding with increased consumption of these antimicrobials during this period. While the COVID-19 pandemic did not alter the overall bacterial trends in pediatric BSIs, it was associated with the emergence of fungal infections and rising MICs-even in the absence of increasing resistance rates. These findings reinforce the importance for continuous AMR surveillance in pediatric populations.

A closer examination of the history of U.S. strategy toward China reveals a pattern of change and fluctuation. This variability is closely linked to a series of significant events. The most impactful event influencing U.S.-China relations has been COVID-19, as an unprecedented crisis. The research problem lies in the differing perspectives regarding the extent to which the United States may seek to exploit COVID-19. Thus, the main question is: How did COVID-19 impact the U.S. approach toward China?. Therefore, the hypothesis is that the coronavirus pandemic serves as a strategic loophole that the USA is attempting to leverage to curb China's rise in the twenty-first century. It may represent a gradual threat to U.S. hegemony. In conclusion, if China's rise intensifies in pursuit of global expansion, challenging unilateral dominance, the United States will likely increase its strategic activities aimed at countering China. Finally, both countries are on a trajectory of managed escalation.
