ABSTRACT

Background: Coronavirus disease (COVID-19) vaccines play an essential role in boosting immunity, preventing severe diseases, and alleviating the Covid-19 health crisis. Objective: This study aimed to explore the type and severity of short-term adverse reactions associated with BNT162 (Pfizer-BioNTech), mRNA 1273 (Moderna), and viral vector vaccines and to compare the incidence of post-vaccination Covid-19 infection among the Birzeit University community in Palestine. Methods: This questionnaire-based retrospective cross-sectional study was conducted among individuals who were vaccinated with at least one dose of any COVID-19 vaccine offered in Palestine during the COVID-19 pandemic. The study included participants aged 18 years and older who were vaccinated with Pfizer, Moderna, Sputnik Light, or Sputnik v. Results: A total of 558 participants who were administered COVID-19 vaccine were included in the study. Sputnik (239), Pfizer vaccine recipients (236), and Moderna vaccine recipients (83). Of the viral vector vaccine recipients, 57 (23.8%) had a post-vaccination infection, compared to 30 (12.7%) for Pfizer and seven (8.4%) for Moderna. Furthermore, the reported adverse effects in the viral victor group were higher than those in the Moderna and Pfizer groups (71.7, 66.3, and 61.9%, respectively). Chills, headache, fatigue, abdominal pain, and joint pain were significantly higher in the Viral Vector vaccine group than the Moderna and Pfizer vaccine. Vomiting, tiredness, and fatigue were significantly less likely to be complained of by Pfizer vaccine recipients compared to Moderna and Viral Vector vaccine recipients (p < 0.05). Conclusions: Breakthrough infections were associated with both viral vectors and mRNA; however, the mRNA vaccine had less reported post-vaccine infection. Furthermore, the Pfizer/BioNTech COVID-19 vaccine group reported fewer commonly reported side effects (fever, chills, headache, fatigue, muscle pain, joint pain, nausea, and dizziness), followed by the Moderna and viral vector vaccines. Females and underweight participants experienced more adverse effects with both vaccines, and fewer common side effects were reported by all participants.

ABSTRACT

mRNA vaccines have been a critical tool in combating the current coronavirus disease 2019 (COVID-19) pandemic and demonstrated a high safety profile. However, rare cases of isolated oculomotor nerve palsy following vaccination have been reported. These few reported cases can be divided into two groups based on symptom onset: immediate and delayed. While most reported cases involving Pfizer and Moderna vaccines occurred within the first few days of vaccination, a few cases with delayed onset have also been described. We present a unique case of a patient experiencing isolated, unilateral oculomotor nerve palsy 14 days after receiving a Moderna booster shot. Notably, our case and a previously reported case of 17-day onset case share the interesting finding of positive ganglioside antibodies. This not only highlights the potential for unusual occurrences following COVID-19 vaccination but also opens up avenues for exploring the underlying mechanisms behind these events.

ABSTRACT

Introducción Presentamos un paciente diagnosticado de narcolepsia de tipo 1 que desarrolló una encefalitis autoinmune posvacunal y/o tras una infección por el SARS-CoV-2. Caso clínico Paciente de 23 años que es remitido a urgencias por trastorno del lenguaje y temblor, acompañados de cefalea, trastorno del comportamiento, disfunción autonómica, crisis focal motora derecha y letargo. El paciente había sido vacunado siete semanas antes con la primera dosis de la vacuna Moderna (ARN mensajero) y, cuatro semanas después de la vacunación, presentó una infección por el SARS-CoV-2 con test de antígenos positivo. Resultados La exploración neurológica mostró un nivel de conciencia normal y una afasia mixta de predominio motor (campimetría, pares craneales, reflejos y sensibilidad normales). El test de reacción en cadena de la polimerasa para la COVID-19 fue negativo. En el líquido cefalorraquídeo se apreció una linfocitosis y proteínas elevadas. Los cultivos para hongos y bacterias fueron negativos. Los anticuerpos onconeuronales fueron normales. La resonancia magnética cerebral mostró en la secuencia de difusión una restricción con afectación cortical y morfología giral en el hemisferio cerebral izquierdo, y distribución parcheada con afectación de lóbulo frontal y temporal izquierdos. Una tomografía axial computarizada de tórax-abdomen-pelvis fue normal, al igual que las ecografías pélvica y escrotal. Al paciente se le trató con plasmaféresis y corticoides, con buena evolución clínica y resolución casi completa de las anomalías en la neuroimagen. Conclusión Se trata de un paciente con narcolepsia de tipo 1 con criterios de encefalitis autoinmune de comienzo subagudo. La infección por el SARS-CoV-2 o la vacunación, o ambas, constituyen un riesgo para desarrollar una o más enfermedades autoinmunes con la edad –como sucede en este caso–, lo que permite comprender la implicación de procesos inmunomediados en la fisiopatología de estas enfermedades.

INTRODUCTION We present a narcolepsy type 1 patient that develop an autoimmune encephalitis post vaccine and/or a SARS-CoV-2 infection.CASE REPORTAt 23 years old, the patient was referred to the emergency room with difficult speaking, headache and tremor followed by changes in behavior, autonomic dysfunction, right focal motor seizure and lethargy. He has received seven weeks before mRNA-1273 (Moderna) vaccine followed by a SARS-CoV-2 infection four weeks after vaccination (positive antigen test).RESULTSThe neurological examination was normal (visual fields, cranial nerves, motor, sensory and reflexes). Nasopharyngeal swab polymerase chain reaction (PCR) testing for COVID-19 was negative. Cerebrospinalfluid (CSF) had highly elevated protein and lymphocytic pleocytosis. CSF bacterial and fungal cultures for viral infections were negative. Brain magnetic resonance imaging (MRI) showed no abnormality on the non-enhanced sequences but the diffusion weighted imaging showed restricted diffusion with high signal on the left hemisphere mainly in the cerebral cortex with a gyro morphology, patched distribution with involvement of the temporal and frontal lobes. Chest, abdomen and pelvis computed tomography; pelvic and scrotum ultrasound, showed no malignancy. Onconeural antibodies were negative. The patient was treated with plasmapheresis and corticosteroids with a good clinical outcome and near complete resolution of the MRI abnormalities. CONCLUSION. The patient fulfilled the diagnostic criteria for autoimmune encephalitis with subacute onset. COVID-19 infection and vaccination could constitute a risk in a patient with narcolepsy as in this case and, could help to provide better understanding of the implication of immune-mediated processes in the pathophysiology of the diseases.

ABSTRACT

El conocimiento sobre alimentación en los hospitales de laedad moderna en España está sustentado en documentaciónde muy pocos centros, mayoritariamente de grandes urbes,siendo necesarias nuevas aportaciones para ampliar la evidenciaexistente. A tal objeto se ha analizado la documentación delhospital Santiago de Vitoria, un hospital y una ciudad másrepresentativos de la mediana peninsular.Se ha hallado un inequívoco enfoque económico de ladocumentación sobre alimentos y la consignación de suadquisición solo recoge gastos extraordinarios, mayoritariamentealimentos destinados a la botica (80% de los asientos). Ladieta basal solo nos es conocida por su descripción teórica,anotándose su gasto por número de raciones o su fracción.Se evidencia una supervisión triple en su preparación yadministración, así como una cuidada prescripción médicade los alimentos en las dietas individualizadas.En conclusión, los gastos no evidencian el consumo efectivo nitampoco representan la dieta real, pues la inmensa mayoría delos alimentos consignados estuvieron destinados a la botica yno a la alimentación de los enfermos. Debe preguntarse si losestudios precedentes, que utilizan también datos de gastos,no han hecho una mala interpretación de estos extrapolandoerróneamente una dieta magnífica cuando, en el caso vitoriano,tuvo una composición de clases populares.


Knowledge of hospital food in modern-age hospitals in Spainis based on documentation from very few centers, mostlyin large cities, and new contributions are needed to expandthe existing evidence. To this end, the documentation of theSantiago de Vitoria hospital has been analysed, a hospital nd a city more representative of the peninsular median.An unequivocal economic focus has been found in thedocumentation on foodstuffs, and the record of their acquisitiononly includes extraordinary expenses, mainly foodstuffsdestined for the apothecary's shop (80% of the entries). Thebasal diet is only known to us by its theoretical description,and its expenditure is recorded by number of portions ortheir fraction. There is evidence of triple supervision in itspreparation and administration, as well as careful medicalprescription of the food in the individualised diets.In conclusion, the expenditures do not show the actualconsumption, nor do they represent the real diet, since thevast majority of the food items recorded were destined for thepharmacy and not for the feeding of the sick. It must be askedwhether previous studies, which also use expenditure data,have not misinterpreted these data by wrongly extrapolatinga magnificent diet when, in the case of Vitoria, it was madeup of the working classes.(AU)


O conhecimento da alimentação hospitalar nos hospitais daIdade Moderna em Espanha baseia-se na documentação deum número muito reduzido de centros, principalmente nasgrandes cidades, e são necessárias novas contribuições paraampliar a evidência existente. Para o efeito, analisámos adocumentação do hospital de Santiago de Vitoria, um hospitale uma cidade mais representativos da mediana peninsular.Na documentação relativa aos géneros alimentícios, encontramosum enfoque económico inequívoco, sendo que o registoda sua aquisição apenas inclui despesas extraordinárias,sobretudo géneros destinados à botica (80% das entradas).A dieta basal só nos é conhecida pela sua descrição teórica,e a sua despesa é registada pelo número de porções oupela sua fração. Há indícios de uma tripla vigilância na suapreparação e administração, bem como de uma cuidadosaprescrição médica dos alimentos nas dietas individualizadas.Em conclusão, as despesas não mostram o consumo real nemrepresentam a dieta real, uma vez que a grande maioria dosalimentos registados se destinava à farmácia e não à alimentaçãodos doentes. É de perguntar se estudos anteriores, que tambémutilizam dados de despesas, não terão interpretado mal estesdados, extrapolando erradamente uma dieta magnífica quando,no caso de Vitória, era constituída pelas classes populares.(AU)

ABSTRACT

Aquellas investigaciones orientadas a analizar las actitudes hacia la homosexualidad sugieren el uso de instrumentos que detecten los aspectos sutiles en la discriminación hacia hombres gais y mujeres lesbianas. Asimismo, se señala que la invariancia de medida de los constructos es imprescindible para que las comparaciones entre grupos sean válidas. Este trabajo pretende validar la Escala de Homonegatividad Moderna (MHS) en estudiantes universitarios del ámbito de la educación (N = 1.283) con un rango de edad entre los 17 y los 49 años (M = 2.88; DT = 3,02). Del mismo modo, se interesa por examinar la invariancia de medida de la MHS en relación con ciertas variables sociodemográficas y personales (p. ej. identidad de género), así como ideológicas (p. ej. inclinación política). Los resultados aportaron evidencias sobre la unidimensionalidad de la escala y un alto grado de consistencia interna (wMHS-G = .879; wMHS-L = .906), además de unos índices de ajuste (CFIMHS-G = .95, CFIMHS-L = .97; RMSEAMHS-G = .064, 90% IC: .057-.071, RMSEAMHS-L = .059, 90% IC: .052-.066) y unos valores de validez externa (MHS-G y AN-T: r = .753, I.C. 95% = .722-.785; MHS-L y AN-T: r = .76. I.C. 95% = .730-.790) satisfactorios. Asimismo, sugirieron que tanto la subescala hacia hombres gais (MHS-G) como mujeres lesbianas (MHS-L) son constructos invariantes conforme a las variables estudiadas. Las conclusiones apuntan a la validez y la invariancia de medida del modelo propuesto para comparar los niveles de homonegatividad moderna entre los grupos estudiados.(AU)


The research aimed at analysing attitudes towards homosexuality recommends the use of instruments that can detect subtle aspects of dis-crimination against gay men and lesbian women. It also asserts that the measurement invariance of constructs is essential for valid comparisons between groups. The present study aims to validate the Modern Ho-monegativity Scale (MHS) in university students in the fieldof education (N= 1.283) with an age range of 17 to 49 years old (M = 2.88; SD = 3.02). In addition, we seekto examine the measurement invariance of the MHS in relation to certain sociodemographic and personal variables (e.g. gender identity), as well as ideological variables (e.g. political inclination). The re-sults provided evidence of the scale'sunidimensionality and a high degree of internal consistency (MHS-G= .879; MHS-L= .906), as well as satisfac-tory fit indices (CFIMHS-G= .95, CFIMHS-L= .97; RMSEAMHS-G= .064, 90% CI: .057-.071, RMSEAMHS-L= .059, 90% CI: .052-.066) and external validity values (MHS-G and AN-T: r= .753, CI 95% = .722-.785; MHS-L and AN-T: r= .76. CI 95% = .730-.790). They also indicated that both the subscales –towards gay men (MHS-G) and lesbian women (MHS-L) –are invariant constructs according to the variables studied. The findings point to the validity and measurement invariance of the proposed model for comparing levels of modern homonegativity between the groups studied.(AU)

ABSTRACT

Background: The aim of the study was to evaluate the humoral and cellular immunity after SARS-CoV-2 infection and/or vaccination according to the type of vaccine, number of doses and combination of vaccines. Methods: Volunteer subjects were sampled between September 2021 and July 2022 in Hospital Clínico San Carlos, Madrid (Spain). Participants had different immunological status against SARS-CoV-2: vaccinated and unvaccinated, with or without previous COVID-19 infection, including healthy and immunocompromised individuals. Determination of IgG against the spike protein S1 subunit receptor-binding domain (RBD) was performed by chemiluminescence microparticle immunoassay (CMIA) using the Architect i10000sr platform (Abbott). The SARS-CoV-2-specific T-cell responses were assessed by quantification of interferon gamma release using QuantiFERON SARS-CoV-2 assay (Qiagen). Results: A total of 181 samples were collected, 170 were from vaccinated individuals and 11 from unvaccinated. Among the participants, 41 were aware of having previously been infected by SARS-CoV-2. Vaccinated people received one or two doses of the following vaccines against SARS-CoV-2: ChAdOx1-S (University of Oxford-AstraZeneca) (AZ) and/orBNT162b2 (Pfizer-BioNTech)(PZ). Subjects immunized with a third-booster dose received PZ or mRNA-1273 (Moderna-NIAID)(MD) vaccines. All vaccinees developed a positive humoral response (>7.1 BAU/ml), but the cellular response varied depending on the vaccination regimen. Only AZ/PZ combination and 3 doses of vaccination elicited a positive cellular response (median concentration of IFN- γ > 0.3 IU/ml). Regarding a two-dose vaccination regimen, AZ/PZ combination induced the highest humoral and cellular immunity. A booster with mRNA vaccine resulted in increases in median levels of IgG-Spike antibodies and IFN-γ as compared to those of two-dose of any vaccine. Humoral and cellular immunity levels were significantly higher in participants with previous infection compared to those without infection. Conclusion: Heterologous vaccination (AZ/PZ) elicited the strongest immunity among the two-dose vaccination regimens. The immunity offered by the third-booster dose of SARS-CoV-2 vaccine depends not only on the type of vaccine administered but also on previous doses and prior infection. Previous exposure to SARS-CoV-2 antigens by infection strongly affect immunity of vaccinated individuals.

ABSTRACT

Nos últimos 40 anos, a atuação do psicólogo vem sendo orientada pela aproximação a diversas políticas públicas. A despeito dos avanços empreendidos quanto à capacitação das profissionais para o trabalho com beneficiários de tais políticas, os cursos de graduação ainda parecem carecer de um foco maior no estudo de tais políticas e de uma consolidação de referenciais teórico-metodológicos e epistemológicos de atuação psicológica. O presente ensaio busca discutir criticamente o papel dos fundamentos históricos e epistemológicos da psicologia na formação para atuação em políticas sociais, compreendendo um estudo teórico, de base bibliográfica e documental, acerca das discussões histórico-epistemológicas no campo psicológico. Destaca-se que tais discussões tanto oferecem a base para o desenvolvimento do senso crítico acerca da psicologia enquanto área dispersa e fragmentada quanto também possibilitam o desvelamento da condição escamoteada da psicologia enquanto saber auxiliar ao controle subjetivo e ideológico dos indivíduos pelo Estado.


For the last 40 years, the work of psychologists has been oriented by approaching several social policies. Despite advances in terms of professional training and education to work with beneficiaries of such policies, Psychology undergraduate courses still seem to lack the necessary emphasis on the study of such policies and on the consolidation of epistemological, theoretical, and methodological references for psychological practice. This essay critically discusses the role of the epistemological and historical foundations of Psychology on professional training to act in social policies, through a theoretical, bibliographical, and documental study about the historical-epistemological discussions in the Psychology field. It is noteworthy that such discussions set the basis for the development of critical thinking on Psychology as fragmented and scattered area, as well as enable to unveil the concealed condition of Psychology as an auxiliary knowledge for the subjective and ideologically control of individuals by the State.

ABSTRACT

Delayed hypersensitivity reactions (DHRs) have been reported in association with COVID-19 vaccines, particularly those that are mRNA-based. Classic DHRs result in induration, erythema, tenderness, and urticaria. However, soft tissue mass is an uncommon complication of a COVID-19 vaccination-associated DHR and is rarely reported in the literature. We present a case of a 49-year-old male who recognized a mildly painful, firm soft tissue mass within the biceps mimicking neoplasm six months after receiving the booster dose of the Moderna vaccine. Non-operative conservative treatment modalities, including heating pads, ice packs, acetaminophen, and ibuprofen, failed to improve the patient's mass. The mass, which proved histologically to be an inflammatory pseudo-tumor, did not recur after complete excision. While there have been many reported cases of DHRs following COVID-19 vaccinations, we present this case to raise awareness of the development of pseudo-tumors as a possible, yet rare, clinical manifestation of DHRs following vaccination.

ABSTRACT

Children with very early onset inflammatory bowel disease (VEO-IBD) may respond differently to coronavirus disease 2019 (COVID-19) immunization compared to healthy children or other patients with IBD. We recruited children with VEO-IBD <6 years of age and younger following receipt of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Demographics, IBD characteristics, medication use, adverse events (AEs) and IBD exacerbations were collected. Blood draws (optional) were obtained for measurement of antireceptor binding domain (RBD) IgG antibodies following vaccination. Of 41 participants, none required emergency department visit or hospitalization due to AE, and only one experienced IBD exacerbation. Detectable antibody was present in 19/19 participants who provided blood sample; 6/7 participants (86%) had durable humoral response 12 months postvaccination. Children with VEO-IBD experience robust humoral immune response to COVID-19 immunization. Severe AEs were rare. These findings provide reassurance that children with VEO-IBD respond well and safely to SARS-CoV-2 vaccination.

ABSTRACT

Introduction: This study sought to elucidate the long-term antibody responses to the Moderna mRNA-1273 COVID-19 vaccine within a Ugandan cohort, aiming to contribute to the sparse data on m-RNA vaccine immunogenicity in Sub-Saharan Africa. Methods: We tracked the development and persistence of the elicited antibodies in 19 participants aged 18 to 67, who received two doses of the mRNA-1273 vaccine. A validated enzyme-linked immunosorbent assay (ELISA) was used to quantify SARS-CoV-2-specific IgG, IgM, and IgA antibodies against the spike (S) and nucleoproteins (N). The study's temporal scope extended from the baseline to one year, capturing immediate and long-term immune responses. Statistical analyses were performed using the Wilcoxon test to evaluate changes in antibody levels across predetermined intervals with the Hochberg correction for multiple comparisons. Results: Our results showed a significant initial rise in spike-directed IgG (S-IgG) and spike-directed IgA (S-IgA) levels, which remained elevated for the duration of the study. The S-IgG concentrations peaked 14 days afterboosting, while spike-directed IgM (S-IgM) levels were transient, aligning with their early response role. Notably, post-booster antibody concentrations did not significantly change. Prior S-IgG status influenced the post-priming S-IgA dynamics, with baseline S-IgG positive individuals maintaining higher S-IgA responses, a difference that did not reach statistical difference post-boost. Three instances of breakthrough infections: two among participants who exhibited baseline seropositivity for S-IgG, and one in a participant initially seronegative for S-IgG. Discussion: In conclusion, the mRNA-1273 vaccine elicited robust and persistent S-IgG and S-IgA antibody responses, particularly after the first dose, indicating potential for long-term immunity. Prior viral exposure enhances post-vaccination S-IgA responses compared to naive individuals, which aligned with the prior-naïve, post-boost. The stable antibody levels observed post-booster dose, remaining high over an extended period, with no significant secondary rise, and no difference by baseline exposure, suggest that initial vaccination may sufficiently prime the immune system for prolonged protection in this population, allowing for potential to delay booster schedules as antibody responses remained high at the time of boosting. This finding calls for a reassessment of the booster dose scheduling in this demographic.

ABSTRACT

AIMS & OBJECTIVES: The objective of this study was to conduct a systematic review of research pertaining to the COVID-19 vaccine and its association with neurological complications. METHOD: We performed a comprehensive search of the literature using Google Scholar, PubMed, and NCBI databases from December 2021 to December 2022. For Google Scholar, PubMed, and NCBI databases we used the following key search terms: "neurological adverse effects", "COVID-19 vaccination", "SARS-CoV-2", CNS complications, and CNS adverse effects. Two reviewer authors individually searched and assessed the titles and abstracts of all articles. The third reviewer resolved the disagreement between them. Data were documented regarding title, study location, type of study, type of COVID-19 vaccine, type of neurological complications/adverse effects, and sample size. RESULTS: From our findings, it is confirmed that these neurological complications like GuillainBarre syndrome (23.6%), Neuromyelitis Optica spectrum disorder (5.5%), Neuropathy (6.9%), Transverse Myelitis (8.3%) and Acute disseminated Encephalomyelitis (4.1%) are majorly affected in most of the people. The increase in risks associated with SARS-CoV-2 infection far outweighs any previously reported associations with vaccination. CONCLUSION: We found no safety signal was observed between COVID-19 vaccines and the immune-mediated neurological events. Before assuming a causal relationship, the side effects of the COVID-19 vaccine should first be carefully examined to rule out known associated factors. Symptom onset was within two weeks of vaccination in the majority of cases; as such, this seems to be a high-risk period warranting vigilance.

ABSTRACT

Most Australian adults now have hybrid immunity to the SARS-CoV-2 virus, referring to a combination of protection from previous vaccine doses and past infection. Protection from both vaccination and past infection wanes over time. Booster doses are recommended to ensure that those who are at increased risk of severe COVID-19 remain protected. The optimal timing of future booster doses to maintain adequate protection against severe illness is not yet known. Older age remains the most important risk factor for severe COVID-19, including in the current Omicron variant era. The original COVID-19 vaccines are monovalent vaccines based on the ancestral strain of the SARS-CoV-2 virus. Bivalent vaccines have been developed based on earlier Omicron subvariants (BA.1 or BA.4-5) and the ancestral strain. These provide enhanced protection against severe illness from Omicron compared with the original monovalent vaccines. Updated monovalent vaccines based on a more recent Omicron subvariant (XBB.1.5) have been developed. COVID-19 vaccines have an excellent safety record, and serious adverse events are extremely rare.

ABSTRACT

Vaccination with the primary two-dose series of SARS-CoV-2 mRNA protects against infection with the ancestral strain, and limits the presentation of severe disease after re-infection by multiple variants of concern (VOC), including Omicron, despite the lack of a strong neutralizing response to these variants. We compared antibody responses in serum samples collected from mRNA-1273 (Moderna) vaccinated subjects to identify mechanisms of immune escape and cross-protection. Using pseudovirus constructs containing domain-specific amino acid changes representative of Omicron BA.1, combined with domain competition and RBD-antibody depletion, we showed that RBD antibodies were primarily responsible for virus neutralization and variant escape. Antibodies to NTD played a less significant role in antibody neutralization but acted along with RBD to enhance neutralization. S2 of Omicron BA.1 had no impact on neutralization escape, suggesting it is a less critical domain for antibody neutralization; however, it was as capable as S1 at eliciting IgG3 responses and NK-cell mediated, antibody-dependent cell cytotoxicity (ADCC). Antibody neutralization and ADCC activities to RBD, NTD, and S1 were all prone to BA.1 escape. In contrast, ADCC activities to S2 resisted BA.1 escape. In conclusion, S2 antibodies showed potent ADCC function and resisted Omicron BA.1 escape, suggesting that S2 contributes to cross-protection against Omicron BA.1. In line with its conserved nature, S2 may hold promise as a vaccine target against future variants of SARS-CoV-2.

ABSTRACT

COVID-19 vaccines were originally authorized in the United States in December 2020 on the basis of safety, immunogenicity, and clinical efficacy data from randomized controlled trials (RCTs). However, real-world vaccine effectiveness (VE) data are necessary to provide information on how the vaccines work in populations not included in the RCTs (e.g., nursing home residents), against new SARS-CoV-2 variants, with increasing time since vaccination, and in populations with increasing levels of prior infection. The goal of CDC's COVID-19 VE program is to provide timely and robust data to support ongoing policy decisions and implementation of vaccination and includes VE platforms to study the spectrum of illness, from infection to critical illness. Challenges to estimating VE include accurate ascertainment of vaccination history, outcome status, changing rates of prior infection, emergence of new variants, and appropriate interpretation of absolute and relative VE measures. CDC COVID-19 VE platforms have played a pivotal role in numerous vaccine policy decisions since 2021 and will continue to play a key role in future decisions as the vaccine program moves from an emergency response to a routine schedule.

ABSTRACT

This pilot study explores alterations in miRNA profiles among pregnant women and their neonates upon receiving different doses of COVID-19 vaccines. Blood samples, including maternal blood (MB) and neonatal cord blood (CB), collected from five pregnant women were scrutinized using the miRNA PanelChip Analysis System, identifying nine distinct miRNAs, including miR-451a and miR-1972, which exhibited significant downregulation with two vaccine doses in both MB and CB. When compared with women vaccinated with four doses, miR-486-5p, miR-451a, and miR-1972 in the two-dose group also showed notable downregulation. Evaluating recipients of three and four doses, miR-423-5p and miR-1972 expression were significantly reduced in both MB and CB. Further comparative analysis highlighted a decline in miR-223-3p expression with increasing vaccine doses, while miR15a-5p, miR-16-5p, and miR-423-5p showed an upward trend. Notably, miR-451a, miR-1972, and miR-423-5p levels varied across doses and were associated with pathways such as "PI3K-Akt", "neurotrophin signaling", and "cortisol synthesis", suggesting the profound influence of vaccination on diverse molecular mechanisms. Our research has uncovered that escalating vaccine dosages impact miRNA profiles, which may be associated with the immunological response mechanisms in both the mother and fetus, thus indicating a substantial impact of vaccination on various molecular processes.

ABSTRACT

Introduction: Vaccination against coronavirus disease 2019 (COVID-19) is essential for controlling the ongoing cases of this disease. Citrobacter infections of the bones and joints are extremely uncommon. Thromboembolism and deep vein thrombosis (DVT) are very rare complications. Case presentation: The authors present a rare case of osteomyelitis, septic arthritis, deep venous thrombosis, and pulmonary embolism in a 15-year-old previously healthy boy occurring shortly after receiving the second dose of the Moderna COVID-19 vaccine. He experienced pain, swelling in the right leg, shortness of breath, and fever, followed by chest pain and leg edema. Treatment included anticoagulation, ketorolac for pain management, antipyretics, and intravenous antibiotics (Tazobactam/Piperacillin, Linezolid, Clindamycin) for osteomyelitis. Discussion: The risk of COVID-19 vaccine-related thrombotic events is minimal. Thrombotic events reported among mRNA is very rare. Citrobacter freundii bone and joint infections are very rare, accounting for a small percentage of cases. Some documented cases include cefotaxime-resistant strains causing necrotizing fascitis and osteomyelitis, including postarthroplasty infections. Due to the diverse range of susceptibility patterns and the widespread occurrence of drug resistance, personalized treatment based on culture and sensitivity testing is recommended. However, in rare cases, severe complications like DVT and joint infections associated with Citrobacter infection may occur and should be reported to the vaccine adverse events reporting system. Conclusion: Administering the COVID-19 vaccine to enhance natural antibodies is crucial, despite the low risk of infection, thromboembolism, and DVT. Healthcare providers should stay vigilant about adverse effects postvaccination and promptly report those cases.

ABSTRACT

OBJECTIVE: To examine SARS-CoV-2 vaccine-related headache characteristics and risk factors in migraine patients. METHODS: This retrospective cohort study included 732 migraine patients who had AstraZeneca Vaxzevria, Pfizer-BioNTech Comirnaty, or Moderna Spikevax vaccines. Participants provided information through questionnaires and headache diaries. Headache frequency before and after vaccination and factors associated with headache risk were examined. RESULTS: Approximately a third of patients reported increased headache the day after having primary and booster doses, with mean increase ± SD of 1.9 ± 1.2 and 1.8 ± 1.1 days/week, respectively. Proportions of migraine patients with headache (after vaccination vs. before vaccination) increased after having primary-dose Vaxzevria (35.3% vs. 22.8%, p < 0.001) but not Spikevax (23.8% vs. 26.7%, p = 0.700) or Comirnaty (33.2% vs. 25.8%, p = 0.058). Headache proportion increased after having all three boosters (Vaxzevria 27.1% vs. 17.9% p = 0.003; Comirnaty 34.1% vs. 24.5% p = 0.009; Spikevax 35.2% vs. 24.8% p = 0.031). For primary dose with Vaxzevria and Comirnaty, headache risk increased on the vaccination day, peaked on the day after vaccination, and subsided within a week, while for Spikevax headache risk rose gradually after vaccination, peaked on the seventh post-vaccination day and subsided subsequently. For booster dose, headache risk generally increased on the vaccination day, peaked on the day after vaccination, and subsided gradually with fluctuating pattern within a month. Our study also showed that headache increased on the day before primary dose but not booster dose vaccination and it may be attributable to stress associated with having to undertake new vaccines. Multivariable analyses showed that depression was associated with headache. CONCLUSION: Prolonged headache with vaccine- and dose-specific headache pattern was found. Patients with higher risks of vaccine-related headache must be informed of the potential worsening headache.

ABSTRACT

Introducción: con ser importante, la alimentación en los hospitales medievales y modernos distó de la excelencia y abundancia que sugierenalgunos historiadores, probablemente por una incorrecta valoración de la documentación hospitalaria al considerar como destinado a la alimentación todo gasto en alimentos, cuando buena parte tuvo como destino la botica.Objetivo/método: identificar los alimentos utilizados para una finalidad terapéutica no nutricional durante la edad moderna en el Hospital deSantiago Apóstol de Vitoria (Álava, España), describir su sistema de consignación y revisar la bibliografía del periodo para facilitar estrategias devaloración documental a los investigadores.Resultados: entre 1592 y 1813 se identifican 42 grupos de alimentos adquiridos para finalidades terapéuticas no nutritivas. El sistema deanotación en los libros de gastos no es sistemático ni homogéneo sino muy variable y dependiente de quien efectuara el asiento. Se identifican27 términos para el reconocimiento de que un determinado alimento tuviera por destino la botica y no la cocina. Se escogen 14 textos sanitariosdel periodo como bibliografía clarificadora, encontrándose de mayor utilidad para los fines propuestos los manuales enfermeros del siglo XVII.Conclusiones: la variedad y cantidad de alimentos destinados a la botica evidencia el riesgo de confusión en los investigadores no familiarizadosal analizar las dietas hospitalarias desde los libros de contabilidad. La propuesta de términos y estrategias de discriminación del uso nutricionalo no nutricional de los alimentos adquiridos, junto a la recomendación bibliográfica, resulta indispensable para una adecuada valoración de lasdietas hospitalarias históricas.

Introduction: although important, food in medieval and modern hospitals was far from the excellence and abundance suggested by somehistorians, probably due to an incorrect assessment of hospital documentation, considering all food expenditure to be for food when much of itwas destined for the apothecary’s shop.Aim/method: to identify the foodstuffs used for non-nutritional therapeutic purposes during the modern age at Hospital de Santiago in Vitoria(Alava, Spain), to describe the system of consignment, and to review the bibliography of the period in order to facilitate documentary assessmentstrategies for researchers.Results: between 1592 and 1813, 42 groups of foodstuffs acquired for non-nutritional therapeutic purposes were identified. The system of annotation in the expenditure books is neither systematic nor homogeneous, but highly variable and dependent on who made the entry. Twenty-seventerms were identified for the recognition that a given foodstuff was intended for the apothecary’s shop and not the kitchen. Fourteen sanitarytexts of the period were chosen as clarifying bibliography, finding the 17th century nursing manuals most useful for the proposed purposes.Conclusions: the variety and quantity of foodstuffs destined for the apothecary’s shop shows the risk of confusion in unfamiliar researcherswhen analysing hospital diets from account books. A proposal of terms and strategies for discriminating the nutritional or non-nutritional use ofthe food acquired, together with bibliographical recommendations, is essential for an adequate assessment of historical hospital diets.

ABSTRACT

OBJECTIVE: This study aims to characterize the adverse events (AEs) following the administration of the mRNA-1273 COVID-19 vaccine from the Vaccine Adverse Event Reporting System (VAERS) data. METHODS: In this case/non-case analysis, reports between 1 January 2021, and 27 October 2022, were extracted from VAERS. AEs were defined as preferred terms (PTs) by Medical Dictionary for Regulatory Activities (MedDRA) terminology. Disproportionality analyses were conducted to calculate the reporting odds and proportional reporting ratios. The Bayesian approach was used to calculate information component (IC) values and Empirical Bayesian Geometric Mean scores for all the AEs detected. RESULTS: 186 MedDRA PTs compromising 702,495 AEs associated with the mRNA-1273 vaccine were identified. Three statistically significant signals were identified for general and systemic AEs, administration site conditions, and product issues. Cardiac disorders were rarely reported, the most common being; 489 reports for 'myocarditis' (19.44%), 475 for 'acute myocardial infarction' (18.88%), 457 for 'myocardial infarction' (18.16%), 290 for 'bradycardia' (11.53%) and 281 for 'pericarditis' (11.17%). CONCLUSIONS: The most frequently identified AEs following mRNA-1273 vaccination agree with those listed within the Summary of Product Characteristics. In addition, disproportionality analysis did not find any statistically significant signals for myocarditis or pericarditis.
