Abstract Public health disease surveillance can guide a range of decisions related to the protection of populations. Economic analysis can be used to assess how surveillance for specific diseases can substitute for or complement other public health interventions and how to structure surveillance most efficiently. Assessing the value and costs of different disease surveillance options as part of broader disease prevention and control efforts is important for both using available resources efficiently to protect populations and communicating the need for additional resources as appropriate.

Abstract Background Understanding antibody responses to SARS-CoV-2 vaccination is crucial for refining COVID-19 immunization strategies. Generation of mucosal immune responses, including mucosal IgA, could be of potential benefit to vaccine efficacy, yet limited evidence exists regarding the production of mucosal antibodies following the administration of current mRNA vaccines to young children.Methods We measured the levels of antibodies against SARS-CoV-2 from a cohort of children under 5 years of age (N=24) undergoing SARS-CoV-2 mRNA vaccination (serially collected, matched serum and saliva samples) or in a convenience sample of children under 5 years of age presenting to pediatric emergency department (nasal swabs, N=103). Further, we assessed salivary and nasal samples for the ability to induce SARS-CoV-2 spike-mediated neutrophil extracellular traps (NET) formation.Results Longitudinal analysis of post-vaccine responses in saliva revealed the induction of SARS-CoV-2 specific IgG but not IgA. Similarly, SARS-CoV-2 specific IgA was only observed in nasal samples obtained from previously infected children with or without vaccination, but not in vaccinated children without a history of infection. In addition, oronasopharyngeal samples obtained from children with prior infection were able to trigger enhanced spike-mediated NET formation, and IgA played a key role in driving this process.Conclusions Despite the induction of specific IgG in the oronasal mucosa, current intramuscular vaccines have limited ability to generate mucosal IgA in young children. These results confirm the independence of mucosal IgA responses from systemic humoral responses following mRNA vaccination and suggest potential future vaccination strategies for enhancing mucosal protection in this young age group.

Abstract HLA-B*58:01 and HLA-B*57 are protective alleles against HIV-1 subtype B or C infection whereas these HLA alleles have not been reported as protective in HIV-1 subtype AE infection. Although HLA-B*58:01-restricted and HLA-B*57-restricted HIV-1-specific CD8+ T cells have been thoroughly analyzed in subtype B or C infection, they have only been partially analyzed in subtype AE infection. We identified six HLA-B*58:01-restricted subtype AE epitopes in Vietnamese individuals infected with subtype AE. HLA-B*58:01-restricted T-cell responses to Gag epitopes, which may control disease progression in HLA-B*58:01+ and HLA-B*57+ individuals infected with subtype B or C, were not protective in subtype AE infection. These findings suggest that the loss of HLA-B*58:01-restricted T cells specific for some Gag epitopes and/or their reduced ability may account for the lack of protective effects conferred by HLA-B*58:01 in subtype AE infection.

Abstract Background Chlamydia trachomatis (CT) is a globally prevalent sexually transmitted infection (STI) that can result in pelvic inflammatory disease, ectopic pregnancy and infertility in women. Currently, there is no prophylactic vaccine.Methods This study examined T cell immunity in a cohort of women recently infected with CT. Participants were screened against peptides spanning 33 of 894 possible CT proteins, either ex vivo or using short-term cell lines (STCL). CT-specific T cells were characterized by IFN-γ ELISpot and flow cytometry.Results Ex vivo CT-specific T cells were rarely detected; however, following in vitro expanded CT-specific T cells were detected by IFN-γ ELISpot in 90% (27/30) of participants. Notably, over 50% of participants had T cell responses targeting chlamydial protease-like activity factor (CPAF). T cell epitopes were dispersed across the CPAF protein. Flow cytometry analysis of STCL found CT-specific cells, were mainly CD4+, produced IFN-γ and TNF-α and were sustained over 12 months. Ex vivo analysis suggested CT-specific T cells mostly exhibited a central memory phenotype.Conclusion Our results indicate that CT infection elicits low-frequency, persistent CD4 T cell responses in most women and that the secreted protein, CPAF, is an immunoprevalent CT antigen. Altogether, these data support development and testing of CT vaccines that enhance CD4 T cells against CPAF.

Abstract The causes of diarrhea after ten years of rotavirus vaccination in Rwanda were investigated in 496 children with and 298 without diarrhea using a real-time PCR. Rotavirus was detected in 11% of children with diarrhea (OR 2.48, P=0.002). Comparison of population attributable fractions (PAF) show that Shigella (PAF=11%) and ETEC-eltB (PAF=12%) have replaced rotavirus as the main causative agents. The PAF for rotavirus had declined from 41% pre-vaccination to 6.5%, indicating that rotavirus has become one among several similarly important causes of childhood diarrhea in Rwanda. A rotavirus genotype shift to G3P[8] points at the importance of continued genotype surveillance.

Abstract Background Few investigations have assessed contributions of both vaginal bacteria and proinflammatory immune mediators to human immunodeficiency virus (HIV) acquisition risk in a prospective cohort.Methods We conducted a nested case-control study of African women who participated in a randomized placebo-controlled trial of daily oral versus vaginal tenofovir-based preexposure prophylaxis for HIV infection. Vaginal concentrations of 23 bacterial taxa and 16 immune mediators were measured. Relationships between individual bacterial concentrations or immune mediators and HIV risk were analyzed using generalized estimating equations in a multivariable model. Factor analysis assessed relationships between combinations of bacterial taxa, immune mediators, and HIV acquisition risk.Results We identified 177 HIV pre-seroconversion visits from 150 women who acquired HIV and 531 visits from 436 women who remained HIV uninfected. Fourteen bacterial taxa and 6 proinflammatory cytokines and chemokines were individually associated with greater HIV risk after adjusting for confounders. Women with all 14 taxa versus

Abstract Evaluating the adaptive immune responses to natural infection with Crimean-Congo hemorrhagic fever (CCHF) virus (CCHFV) in human survivors is critical to the development of medical countermeasures. However, the correlates of protection are unknown. As the most prevalent tick-borne human hemorrhagic fever virus with case fatality rates of 5%–30% and worldwide distribution, there is an urgent need to fill these knowledge gaps. Here, we describe adaptive immune responses in a cohort of Ugandan CCHF survivors via serial sampling over 6 years. We demonstrate persistent antibodies after infection and cross-neutralization against various clades of authentic CCHFV, as well as potent effector function. Moreover, we show for the first time persistent, polyfunctional antigen-specific memory T-cell responses to multiple CCHFV proteins up to 9 years after infection. Together, this data provides immunological benchmarks for evaluating CCHFV medical countermeasures and information that can be leveraged toward vaccine immunogen design and viral target identification for monoclonal antibody therapies.

Before they can determine the pathogens causing sepsis in patients and treat them with a targeted antibiotic, clinicians must wait for the results of a blood culture test, which can often take 2 to 3 days. Now an ultra-rapid test in development that eliminates the need for blood culture may provide same-day answers, according to a study published in Nature.

In the Original Investigation titled “Treatment Failure and Adverse Events After Amoxicillin-Clavulanate vs Amoxicillin for Pediatric Acute Sinusitis,” published in the September 19, 2023, issue of JAMA, incorrect data for treatment failure were reported, as described in the accompanying letter. An error occurred in how the component outcome of days with an antibiotic prescription without an outpatient encounter was captured. While only 1 component of the outcome definition was impacted by the error, it affected the composite outcome, used in the main analysis, and the subgroup sensitivity analyses. This required corrections to the Abstract, Results and Discussion sections of the main text, Figures 2 and 4, and Supplement 1. These errors did not affect the primary results or the conclusions of the article. This article was corrected online.

To the Editor On behalf of my coauthors, I write to report an error in our Original Investigation “Treatment Failure and Adverse Events After Amoxicillin-Clavulanate vs Amoxicillin for Pediatric Acute Sinusitis,” which was published in the September 19, 2023, issue of JAMA. In this study, we compared amoxicillin-clavulanate vs amoxicillin for the treatment of acute sinusitis in a cohort of outpatient children and adolescents aged 17 years or younger with a new outpatient diagnosis of acute sinusitis and a same-day new prescription dispensation of amoxicillin-clavulanate or amoxicillin, using data from a US nationwide health care utilization database. In the original publication, we reported treatment failure was rare (1.7% overall) and serious treatment failure was very rare (0.01%). We also reported no difference in treatment failure between groups, while adverse events, specifically gastrointestinal symptoms and yeast infections, were more frequent among patients treated with amoxicillin-clavulanate.

Amid the rapid changes that spell the progress of our day, we tend to lose enthusiasm for the novelties that are invading modern life in astonishingly quick succession. Civilized man has become blasé. He has come to expect new discoveries and novel inventions at every turn; and, surfeited by their actual production, he reacts with surprise or gratitude only when some exceptional contribution is made. He is prone to forget the dramatic chapters of medicine that have included the evolution of anesthesia and antisepsis with the consequent development of transfusion and reconstructive surgery, almost within the memory of the living. And the routine care of the sick is today taken for granted; it has become a part of everyday experience that scarcely ever calls for special commendation.

In Reply Ms Majeed and colleagues pose important questions regarding our study. First, the COVID-19 pandemic had several possible implications for transplant care. To explore these implications, we reexamined the number of donor heart offers until acceptance as in the original article but censored observations after February 29, 2020, to exclude the COVID-19 period. For both analyses, we maintained the start date of October 18, 2018, because the United Network for Organ Sharing changed heart transplant listing criteria on this date. The pattern was consistent with our original findings, with the median number of offers until acceptance lowest for White women (5; 95% CI, 4-5), followed by Black women (6; 95% CI, 5-7), White men (8; 95% CI, 7-8), and Black men (9; 95% CI, 8-10) (log-rank P

Abstract Background Measles remains a major public health burden worldwide. Parents often hesitate to vaccinate children with chronic diseases. We investigated the association between the percentage of vaccination and chronic diseases and explore hospital infections’ role in the 2017–2019 measles outbreak across northern Vietnam provinces. Methods A total of 2,064 children aged 0–15 years old admitted for measles to the National Children’s Hospital during the outbreak were included in the study. Demographic information, clinical characteristics, vaccination statuses and laboratory examination were extracted from electronic medical records, vaccination records, or interviews with parents when other sources were unavailable. Results The incidence rate that provincial hospitals sent to the National Children’s Hospital was proportional to the population density of their provinces of residence. Early nosocomial transmission of measles was observed before community-acquired cases emerged in many provinces. Among patients aged over 18 months, those with chronic diseases had a proportion of vaccination of 9.4%, lower than patients without chronic diseases at 32.4%. Unvaccinated patients had a higher proportion of hospital-acquired infections with aOR = 2.42 (1.65–3.65), p

Abstract Background Formal assessment of a surveillance system’s features and its ability to achieve objectives is crucial for disease control and prevention. Since the implementation of the mpox surveillance system in Cameroon, no evaluation has been conducted. Methods In a cross-sectional study, we assessed the performance of the mpox surveillance system in accordance with the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) guidelines. We collected mpox surveillance data from 2018 to 2022 and conducted a survey with key stakeholders of the surveillance program. The survey results were summarized. The rates of complete reporting and mpox detection, as well as the time lag between the different stages of surveillance were analyzed using R version 4.1. Results The mpox detection rate was 21.6% (29/134) over the five years under review. Surveillance indicators revealed that a combination of sample types, including vesicles, crust, and blood, was associated with higher case confirmation. Overall, the mpox surveillance system was effective. Weaknesses in terms of simplicity were identified. Most components of the assessed system failed to meet the timeliness and data quality goals, except for the laboratory component, which was commendable. The lack of a computerized shared database and the system’s non-sustainability were a course of concern. Conclusions Despite all identified bottlenecks in the mpox surveillance system in Cameroon, it was found to meet it stipulated goals. Recommendations are made for training on surveillance system features, particularly at the facility/field level. Therefore, there is a crucial need to globally improve the mpox surveillance system in Cameroon for better disease control.

Abstract Purpose To evaluate the diagnosis and management of bacterial meningitis in adult Sudanese patients in accordance with the Infectious Diseases Society of America (IDSA) guidelines for bacterial meningitis management. Patients and methods A cross-sectional, retrospective study design was used to recruit all patients aged > 18 years who were diagnosed with or suspected of having bacterial meningitis and admitted to Wad Medani Teaching Hospital, Gezira State, Sudan, between January 2017 and October 2022. Results In total, 201 patients were included in the analysis. The mean age of the participants was 44.1 ± 21.4 years, and 107 (53.2%) were male. Community-acquired bacterial meningitis accounted for 193 (96%) of the studied patients, and only 8 (4%) of the patients had healthcare-associated meningitis. Neuroimaging was utilized appropriately in 148 (73.6%) patients, blood cultures were not performed entirely, and lumbar puncture was seldom performed in 1 (0.5%) patient. Corticosteroids were appropriately administered to 65 (32.3%) patients, and antibiotics were administered appropriately to only 5 (2.5%) patients. Ceftriaxone 185 (76.1%) was the most frequently utilized antibiotic, followed by vancomycin 23 (9.5%). In terms of overall adherence, this study demonstrated that the IDSA guidelines were not followed at all in the treatment of patients with suspected bacterial meningitis. Conclusion The results of this study contradict the IDSA guidelines for the standard of care for bacterial meningitis. Antibiotic regimens are often incorrect, corticosteroids are administered appropriately in approximately one-third of patients, and neuroimaging is reasonably utilized. This study raises attention to several important issues regarding the diagnosis of bacterial meningitis, including the lack of confirming microbiological tests and the reliance of the diagnosis primarily on CT and clinical examination.

Abstract Background Even though tuberculosis is a common disease among children in developing countries, tuberculous dactylitis is an uncommon form of Skeletal tuberculosis specially with involvement of both the hands and feet. Case Presentation A one-and-a-half-year-old previously healthy female Ethiopian toddler presented to our pediatric outpatient clinic with a history of two-month duration of painful multiple swellings over both her hands and feet. The swelling involved the proximal phalanx of the left index finger, dorsum of the right hand, and dorsum of both feet over the first metatarsal bone. Physical examination, radiologic findings, and histopathology suggested tuberculous dactylitis. The patient was treated with anti-tuberculosis drugs for one year and she showed clinical and radiologic improvement and recovery. Conclusion Tubercular dactylitis should be considered in the differential diagnosis of children from endemic areas presenting with bone and joint pain or swelling. Our experience of a twelve-month course of antitubercular treatment, which is in line with WHO recommendations, for skeletal tuberculosis, showed excellent outcomes.

Abstract Background Premature infants have less physiologic reserve and often delayed vaccination compared to full-term infants. The birth dose of hepatitis B vaccine (HepB-BD) is an essential measure to achieve the goal of "zero infections" of hepatitis B virus in all newborns. However, there are few investigations of hepatitis B vaccination of preterm infants, leading to uncertainty of coverage and insufficient knowledge of factors influencing timely vaccination of this important population. Methods We obtained hepatitis B vaccine (HepB) vaccination histories of premature infants born during 2019–2021 in three provinces from the respective provincial immunization information systems. Extracted data included date of birth, sex, region, and dates of HepB administration. We conducted descriptive analyses that included basic characteristics of the study subjects, HepB-BD administration, and full-series HepB vaccination. Factors potentially influencing HepB-BD and full series vaccination were analyzed by logistic regression. Results There were 1623 premature infants included in the analytic data set. Overall HepB-BD coverage was 71.41%; coverage among premature infants born to mothers with unknown hepatitis B surface antigen (HBsAg) status was 69.57%; coverage was higher at county-level-and-above hospitals (72.02%) than hospitals below county level (61.11%). Full-series HepB coverage was 94.15%; full-series coverage among preterm infants weighing less than 2000 g at birth was 76.92%. Logistic regression showed that the HepB-BD vaccination rate was positively associated with being born to an HBsAg-positive mother and being preterm with high birth weight. Regression analysis for factors influencing full-series HepB coverage showed that being born prematurely was positively associated with full-series coverage and being premature with a very low birth weight was negatively associated with full-series coverage. Conclusions HepB-BD coverage levels in three provinces of China were less than the target of 90%, especially among premature infants born to mothers with unknown HBsAg status and at hospitals below the county level. Screening of pregnant women should be a universal normal standard. Hepatitis B vaccination training should be strengthened in hospitals to improve the HepB-BD vaccination rate of premature infants and to effectively prevent mother-to-child transmission of hepatitis B virus.

Abstract Background and objective Community-acquired pneumonia (CAP) is a common respiratory disease that frequently requires hospitalisation, and is a significant cause of death worldwide. This study aimed to evaluate the usefulness of alpha-1-antichymotrypsin (AACT) as a diagnostic and prognostic biomarker of CAP. Methods We conducted a multicentre prospective cohort study in patients hospitalised with CAP. Plasma AACT levels were measured using a quantitative enzyme-linked immunosorbent assay. Receiver-operating characteristic (ROC) curves and Cox proportional hazards regression were used to assess the association between plasma AACT levels and CAP diagnosis and prognosis. Results A total of 274 patients with CAP were enrolled in the study. AACT levels were elevated in patients with CAP, especially those with severe CAP and non-survivors. The area under the curve (AUC) of AACT and CRP for diagnosing CAP was 0.755 and 0.843. Cox regression showed that CURB-65 and AACT levels were independent predictors of 30-day mortality. ROC curves showed that plasma AACT levels had the highest accuracy for predicting acute respiratory distress syndrome (ARDS), with an AUC of 0.862. Combining AACT with Pneumonia Severity Index and CURB-65 significantly improved their predictive accuracy for predicting 30-day mortality. Conclusion Plasma AACT levels are elevated in patients with CAP, but plasma AACT level is inferior to the C-reactive protein level for diagnosing CAP. The AACT level can reliably predict the occurrence of ARDS and 30-day mortality in patients with CAP.

Abstract Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes widespread changes in epigenetic modifications and chromatin architecture in the host cell. Recent evidence suggests that SARS-CoV-2 non-structural protein 1 (nsp1) plays an important role in driving these changes. Previously thought to be primarily involved in host translation shutoff and cellular mRNA degradation, nsp1 has now been shown to be a truly multifunctional protein that affects host gene expression at multiple levels. The functions of nsp1 are surprisingly diverse and include not only the downregulation of cellular mRNA translation and stability, but also the inhibition of mRNA export from the nucleus, the suppression of host immune signaling, and, most recently, the epigenetic regulation of host gene expression. In this review, we first summarize the current knowledge on SARS-CoV-2-induced changes in epigenetic modifications and chromatin structure. We then focus on the role of nsp1 in epigenetic reprogramming, with a particular emphasis on the silencing of immune-related genes. Finally, we discuss potential molecular mechanisms underlying the epigenetic functions of nsp1 based on evidence from SARS-CoV-2 interactome studies.

by Abdualrahman Saeed Alshehry This study assessed the resilience of nurses in Saudi Arabia during the corona virus 2019 (COVID-19) pandemic and examined its influence on their quality of life (QOL). A sample of 356 nurses was surveyed in this quantitative, cross-sectional study using the Resilience Scale for Nurses and the World Health Organization Quality of Life (WHOQOL-BREF) from October 2020 to March 2021. The nurses reported the highest resilience score on “situational pattern”, while the lowest score was on “relational pattern.” The nurses had good perceptions on their overall QOL and health and rated their “social relationship” as having the highest quality, while their “environmental” domain as having the least quality. Gender, marital status, provision of direct nursing care to COVID-19 patients, “philosophical pattern”, “situational pattern” and “dispositional pattern” had multivariate impacts on the QOL dimensions. The study concluded that being resilient can positively impact the nurses’ QOL during stressful situations, such as the COVID-19 pandemic.

by Julia Smith, Muhammad Haaris Tiwana, Alice Murage, Hasina Samji, Rosemary Morgan, Jorge Andres Delgado-Ron While there is growing literature on experiences of healthcare workers and those providing unpaid care during COVID-19, little research considers the relationships between paid and unpaid care burdens and contributions. We administered a moral distress survey to healthcare workers in Canada, in 2022, collecting data on both paid and unpaid care. There were no significant differences in the proportion of participants providing unpaid care by gender, with both genders equally affected by certain responsibilities such as reduced contact with family/loved ones. However, men were significantly more distressed about specific unpaid care responsibilities. Unpaid care was not significantly associated with differences in intention to leave work. At work, women were significantly more concerned about patients unable to see family, while men were distressed by others mistreating COVID patients. This study enhances understanding of paid and unpaid care relationships, particularly during crises, and proposes an innovative method for assessing unpaid care burdens.

by Sonoko Matsumoto, Takashi Shimizu, Akihiko Uda, Kenta Watanabe, Masahisa Watarai Francisella tularensis is a causative agent of the zoonotic disease tularemia, and is highly pathogenic to humans. The pathogenicity of this bacterium is largely attributed to intracellular growth in host cells. Although several bacterial factors important for the intracellular growth have been elucidated, including the type VI secretion system, the host factors involved in the intracellular growth of F. tularensis are largely unknown. To identify the host factors important for F. tularensis infection, 368 compounds were screened for the negative regulation of F. tularensis subsp. novicida (F. novicida) infection. Consequently, 56 inhibitors were isolated that decreased F. novicida infection. Among those inhibitors, we focused on cucurbitacin I, an inhibitor of the JAK2/ STAT3 pathway. Cucurbitacin I and another JAK2/STAT3 inhibitor, Stattic, decreased the intracellular bacterial number of F. novicida. However, these inhibitors failed to affect the cell attachment or the intrasaccular proliferation of F. novicida. In addition, treatment with these inhibitors destabilized actin filaments. These results suggest that the JAK2/STAT3 pathway plays an important role in internalization of F. novicida into host cells through mechanisms involving actin dynamics, such as phagocytosis.

Kinoshita, Stian Soiland-Reyes Recording the provenance of scientific computation results is key to the support of traceability, reproducibility and quality assessment of data products. Several data models have been explored to address this need, providing representations of workflow plans and their executions as well as means of packaging the resulting information for archiving and sharing. However, existing approaches tend to lack interoperable adoption across workflow management systems. In this work we present Workflow Run RO-Crate, an extension of RO-Crate (Research Object Crate) and Schema.org to capture the provenance of the execution of computational workflows at different levels of granularity and bundle together all their associated objects (inputs, outputs, code, etc.). The model is supported by a diverse, open community that runs regular meetings, discussing development, maintenance and adoption aspects. Workflow Run RO-Crate is already implemented by several workflow management systems, allowing interoperable comparisons between workflow runs from heterogeneous systems. We describe the model, its alignment to standards such as W3C PROV, and its implementation in six workflow systems. Finally, we illustrate the application of Workflow Run RO-Crate in two use cases of machine learning in the digital image analysis domain.
