Imunização da gestante em tempos de pandemia da COVID-19 / Inmunización de mujeres embarazadas en tiempos de pandemia de COVID-19 / Immunization of pregnant women in times of the COVID-19 pandemic

Objetivo: analisar e comparar a imunização de gestantes no período da pandemia da COVID-19 no Oeste do Paraná. Método: pesquisa analítica e transversal, realizada na nona e décima regionais de saúde do Paraná. Participaram 823 puérperas, a coleta de dados foi conduzida por inquérito e informações do prontuário entre setembro a dezembro de 2021. Utilizaram-se análise descritiva e teste de qui-quadrado com nível significância de 5%. Resultados: a nona regional apresentou melhor desempenho na imunização contra Hepatite-B, Influenza, Difteria, Tétano e Coqueluche em comparação à décima regional. A vacinação contra COVID-19 teve baixa adesão em ambas as regionais, cujos motivos foram: medo, opção própria, orientação médica e desejo de esperar o filho nascer. Conclusão: são necessárias novas estratégias e campanhas de sensibilização para aumentar o índice vacinal entre gestantes, sobretudo para a vacina contra COVID-19, considerando as complicações para a saúde materno-infantil.

Objective: analyze and compare the immunization of pregnant women during the COVID-19 pandemic in western Paraná. Method: this is an analytical, cross-sectional study carried out in the ninth and tenth regional health departments of Paraná. A total of 823 puerperal women took part, and data was collected using a survey and information from medical records between September and December 2021. Descriptive analysis and the chi-square test were used, with a significance level of 5%. Results: the ninth region performed better in immunization against Hepatitis-B, Influenza, Diphtheria, Tetanus and Pertussis compared to the tenth region. Vaccination against COVID-19 had low uptake in both regions, the reasons for which were: fear, own choice, medical advice and the wish to wait for the child to be born. Conclusion: new strategies and awareness campaigns are needed to increase the vaccination rate among pregnant women, especially for the COVID-19 vaccine, considering the complications for maternal and child health.

Conclusión: son necesarias nuevas estrategias y campañas de sensibilización para aumentar la tasa de vacunación entre las mujeres embarazadas, especialmente de la vacuna contra la COVID-19, considerando las complicaciones para la salud materna e infantil.

Determinantes del estado de vacunación infantil: abordando la brecha de equidad en República Dominicana-2019 / Determinants of childhood immunization status: addressing the equity gap in the Dominican Republic­2019

Introducción: Las desigualdades amenazan el progreso del país hacia la equidad y la cobertura de vacunación infantil. Siendo la cobertura inferior a la meta del 90% de la Organización Mundial de la Salud. Objetivo: Identificar los determinantes sociales y las desigualdades en el estado de vacunación infantil en República Dominicana, 2019. Métodos: Se realiza un análisis basado en la Encuesta de Indicadores Múltiples por Conglomerados. Incluyendo una muestra ponderada de 1674 niños de 12-23 meses. Se calcula la regresión logística multinomial para identificar factores asociados a la vacunación. Adoptando p<0,05 para significación estadística. Utilizando una razón de probabilidades ajustada con intervalo de confianza del 95%. Empleando HEAT 4.0 para medir desigualdades y SPSS.23 para gestión y análisis de datos. Resultados: La edad media de los niños fue 17,4±3,5 meses. El 33% de ellos estaban completamente vacunados. La cobertura fue significativamente menor entre hijos de madre sin educación [AOR= 7,27; IC95%= 2,98­17,74]. La mayor cobertura se concentra en niños con altos niveles de educación y riqueza. Conclusión: Para lograr una cobertura de vacunación completa y equitativa, las intervenciones de salud pública deben diseñarse para satisfacer las necesidades de grupos de alto riesgo.

Introduction: In the Dominican Republic, inequalities threaten progress towards childhood vaccination equity and coverage, the latter being inferior to the World Health Organization's 90% goal. Objective: Identify the social determinants and inequalities in the state of childhood vaccination in the Dominican Republic, 2019. Methods: An analysis based on the Multiple Indicator Cluster Surveys is conducted. Including a weighted sample of 1674 children aged 12-23 months. The multinomial logistic regression is calculated to identify factors associated with vaccination. Using p<0,05 for statistical significance and an adjusted probability ratio with a 95% confidence interval. Employing HEAT 4.0 to measure inequalities and SPSS.23 for data management and analysis. Results: The children's mean age was 17,4±3,5 months. 33% of them were completely vaccinated. Coverage was significantly lower in children of mothers without education [AOR= 7,27; CI95%= 2,98­17,74]. Coverage was the highest in kids with high levels of education and wealth. Conclusion: To achieve complete and equitable vaccine coverage, public health interventions should be designed to satisfy the needs of high-risk groups.

A rat model of rheumatoid arthritis: TDZD-8 is associated with the protection against the induction of the synovium knee joint IL-17A/GSK3beta/ROS/alpha-SMA axis of fibrosis / Un modelo de rata de artritis reumatoide: TDZD-8 está asociado con la protección contra la inducción del eje de fibrosis de la articulación sinovial de la rodilla IL-17A/GSK3ß/ROS/α-SMA

SUMMARY: Rheumatoid arthritis (RA) that affects the synovial knee joint causes swelling of the synovial membrane and tissue damage. Interleukin-17A (IL-17A) and the enzyme glycogen synthase kinase-3β (GSK3β) are involved in the pathogenesis of RA. The link between IL-17A, GSK3β, the oxidative stress, and the profibrogenic marker alpha-smooth muscle actin (α-SMA) with and without TDZD-8, GSK3β inhibitor has not been studied before. Consequently, active immunization of rats was performed to induce RA after three weeks using collagen type II (COII) injections. The treated group received daily injection of 1 mg/kg TDZD-8 for 21 days following the immunization protocol (COII+TDZD-8). Blood and synovium tissue samples were harvested at the end of the experiment. RA development was confirmed as corroborated by a substantial increase in blood levels of the highly specific autoantibody for RA, anti-citrullinated protein antibody as well as augmentation of reactive oxidative species (ROS) levels measured as lipid peroxidation. RA induction also increased synovium tissue levels of IL-17A and the profibrogenic marker, α-SMA. All these parameters seemed to be significantly (p<0.0001) ameliorated by TDZD-8. Additionally, a significant correlation between IL-17A, ROS, and α-SMA and biomarkers of RA was observed. Thus, knee joint synovium RA induction augmented IL-17A/GSK3β/ROS/α-SMA axis mediated arthritis in a rat model of RA, which was inhibited by TDZD-8.

La artritis reumatoide (AR) que afecta la articulación sinovial de la rodilla provoca inflamación de la membrana sinovial y daño tisular. La interleucina-17A (IL-17A) y la enzima glucógeno sintasa quinasa-3β (GSK3β) están involucradas en la patogenia de la AR. No se ha estudiadol vínculo entre IL-17A, GSK3β, el estrés oxidativo y el marcador profibrogénico actina de músculo liso alfa (α-SMA) con y sin inhibidor de TDZD-8, GSK3β. En consecuencia, se realizó una inmunización activa de ratas para inducir la AR después de tres semanas usando inyecciones de colágeno tipo II (COII). El grupo tratado recibió una inyección diaria de 1 µg/ kg de TDZD-8 durante 21 días siguiendo el protocolo de inmunización (COII+TDZD-8). Se recogieron muestras de sangre y tejido sinovial al final del experimento. El desarrollo de AR se confirmó como lo corroboró el aumento sustancial en los niveles sanguíneos del autoanticuerpo altamente específico para AR, el anticuerpo antiproteína citrulinada, así como el aumento de los niveles de especies oxidativas reactivas (ROS) medidos como peroxidación lipídica. La inducción de AR también aumentó los niveles de tejido sinovial de IL-17A y el marcador profibrogénico, α-SMA. Todos estos parámetros parecían mejorar significativamente (p<0,0001) con TDZD-8. Además, se observó una correlación significativa entre IL- 17A, ROS y α-SMA y biomarcadores de AR. Por lo tanto, la inducción de AR en la sinovial de la articulación de la rodilla aumentó la artritis mediada por el eje IL-17A/GSK3β/ROS/α-SMA en un modelo de rata de AR, que fue inhibida por TDZD-8.

Vacunación contra el SARS-CoV-2 en el personal de salud / Vaccination against SARS-CoV-2 in health personnel

Introducción: El virus Sars-cov2 es el causante de una enfermedad respiratoria, cuyo grado de severidad es variable, de formas sintomáticas leves a graves. Debido a que no se ha encontrado un tratamiento eficaz para hacerle frente a esta patología, se ha puesto el foco en la prevención mediante vacunas. Una población objetivo de la primera y segunda fase de vacunación a nivel país, fue el personal de salud, por lo que se realiza una encuesta para determinar qué tipo de patologías de base presentan, rango etario predominante, si presentaron algún efecto adverso, y cuántas dosis de inmunización recibieron. Objetivos: Describir el porcentaje de vacunación contra Sars-cov2 en el personal de salud, las enfermedades de base, efectos adversos presentados y describir los motivos por el que se evita la vacunación. Materiales y métodos: Se realizó un estudio descriptivo, observacional y transversal mediante una encuesta en línea (Google Forms). En el cuestionario se registraron las siguientes variables: sexo, edad, profesión dentro del área de salud, departamento de residencia, enfermedad de base, dosis principales y de refuerzo recibidas, efectos adversos presentados, necesidad de atención médica posterior y razones por las que no se han aplicado todas las dosis. Resultados: La mayoría de los encuestados fueron parte del personal médico (85.4%), en su mayoría se encontraban entre los 20-29 años y los 40-49 años. El 48.6% no presenta patologías de base. El 96.3% de la población recibió 2 dosis de la vacuna para Sars-cov2. El 46.3% recibió 2 dosis de refuerzo. Discusión: La predisposición a completar el esquema fue más baja de lo esperado, siendo menor de la mitad. La predisposición para recibir la vacuna contra el COVID-19, en la población general fue de 52,02%. Cabe recalcar que el éxito de un programa de vacunación depende de la proporción de la población que desee vacunarse. Conclusión: La vacunación es un medio de prevención por lo que su promoción es un paso importante para evitar la enfermedad grave. Es necesario realizar una buena educación a toda la población sobre la eficacia, las dosis necesarias para obtener inmunidad, los efectos adversos y los motivos que deben retrasar la colocación de las dosis, porque, como se menciona anteriormente, el éxito de un programa de vacunación depende de la proporción de la población que desee vacunarse.

Introduction: The Sars-cov2 virus is the cause of a respiratory disease, whose degree of severity is variable, from mild to severe symptomatic forms. Since no effective treatment has been found to deal with this pathology, the focus has been on prevention through vaccination. A target population for the first and second phase of vaccination at the country level was health personnel. So a online survey is performed to determine what type of underlying pathologies they present, the age range predominance, the side effects displayed and how many doses they received. Objectives: Describe the percentage of vaccination against Sars-cov2 in health personnel, the underlying diseases, adverse effects and, to describe the reasons why vaccination is avoided. Materials and methods: A descriptive, observational and cross-sectional study is carried out using an online survey (Google Forms). The following variables were recorded in the questionnaire: sex, age, profession within the health area, department of residence, underlying disease, main and booster doses received, adverse effects presented, need for subsequent medical attention and reasons why they did not have been applied all the doses. Results: Most of the respondents were part of the medical staff (85.4%), the majority were between 20-29 years and 40-49 years. The 48.6% do not present basic pathologies. The 96.3% of the population received 2 doses of the Sars-cov2 vaccine. 46.3% received 2 booster doses. Discussion: The predisposition to complete the scheme was lower than expected, being less than a half. The predisposition to receive the COVID-19 vaccine in the general population was 52.02%. It should be emphasized that the success of a vaccination program depends on the proportion of the population that wishes to be vaccinated. Conclusion: Vaccination is a way of prevention, so its promotion is an important step to avoid a serious disease. It is necessary to give a good education to the entire population about the efficacy, the necessary doses to obtain immunity, the adverse effects and the reasons that should delay the doses, because, as mentioned above, the success of a vaccination program depends on the proportion of the population that wants to be vaccinated.

Saúde mental e atuação de psicólogos hospitalares brasileiros na pandemia da covid-19 / Health and works of brazilian hospital psychologists in the covid-19 pandemic / Salud mental y actuación de psicólogos en hospitales brasileños en la pandemia del covid-19

Em março de 2020 a situação causada pela covid-19 foi elevada à categoria de pandemia, impactando de inúmeras formas a vida em sociedade. O objetivo deste estudo foi compreender os impactos da pandemia na atuação e saúde mental do psicólogo hospitalar, profissional que atua nos espaços de saúde e tem experienciado mais de perto o sofrimento dos doentes e dos profissionais de saúde frente à covid-19. Trata-se de um estudo exploratório-descritivo com 131 psicólogos que atuam em hospitais. Os profissionais foram convidados a participar através de redes sociais e redes de contatos das pesquisadoras, utilizando-se a técnica Bola de Neve. Foram utilizados dois questionários, disponibilizados na plataforma Google Forms, um abordando os impactos da pandemia sentidos pelos profissionais e outro referente ao sofrimento psíquico. Os dados foram analisados a partir de estatísticas descritivas e inferenciais. Foram observados impactos na atuação de quase a totalidade dos participantes, constatada a necessidade de preparação dos profissionais para o novo cenário, a percepção de pouco apoio institucional e quase metade da população estudada referiu-se a sintomas de sofrimento psíquico considerável desde o início da pandemia. É fundamental dar atenção a sinais e sintomas de sofrimento psíquico, procurando evitar o adoecimento de uma categoria profissional que se encontra na linha de frente do combate aos danos psicológicos da pandemia e cuja própria saúde mental é pouco abordada na literatura.(AU)

In March 2020, the COVID-19 pandemic breakout hugely impacted life in society. This study analyzes how the pandemic impacted hospital psychologists' mental health and performance, professional who more closely experienced the suffering of patients and health professionals in this period. An exploratory and descriptive study was conducted with 131 hospital psychologists. Professionals were invited to participate through the researchers' social and contact networks using the Snowball technique. Data were collected by two questionnaires available on the Google Forms platform, one addressing the impacts felt by professionals and the other regarding psychic suffering, and analyzed by descriptive and inferential statistics. Results showed that almost all participants had their performance affected by the need to prepare for the new scenario, the perceived little institutional support. Almost half of the study sample reported considerable psychological distress symptoms since the beginning of the pandemic. Paying attention to signs and symptoms of psychic suffering is fundamental to avoid compromising a professional category that is on the front line of combating the psychological damage caused by the pandemic and whose own mental health is little addressed by the literature.(AU)

En marzo de 2020, la situación provocada por el COVID-19 se caracterizó como pandemia e impactó el mundo de diversas maneras. El objetivo de este estudio fue comprender los impactos de la pandemia en la salud mental y la actuación del psicólogo en los hospitales, uno de los profesionales que trabaja en espacios sanitarios y que ha experimentado más de cerca el sufrimiento de pacientes y profesionales sanitarios frente al COVID-19. Este es un estudio exploratorio descriptivo, realizado con 131 psicólogos que trabajan en hospitales. Los profesionales recibieron la invitación a participar a través de las redes sociales y redes de contactos de las investigadoras, mediante la técnica snowball. Se utilizaron dos cuestionarios disponibles en la plataforma Google Forms: uno sobre los impactos de la pandemia en los profesionales y el otro sobre el sufrimiento psíquico. Los datos se analizaron a partir de estadísticas descriptivas e inferenciales. Se observaron impactos en el trabajo de casi todos los participantes, la necesidad de preparación de los profesionales para este nuevo escenario, la percepción de poco apoyo institucional, y casi la mitad de la población estudiada reportaron sentir síntomas de considerable angustia psicológica desde el inicio de la pandemia. Es esencial prestar atención a los signos y síntomas del sufrimiento psíquico, buscando evitar la enfermedad de una categoría profesional que está a la vanguardia de la lucha contra el daño psicológico de la pandemia y cuya propia salud mental se aborda poco en la literatura.(AU)

Relatos da pandemia: ser mulher e mãe em tempos de covid-19 / Pandemic reports: being a woman and mother in covid-19 times / Relatos de la pandemia: ser mujer y madre en tiempos del covid-19

Partindo da pergunta "Como tem sido ser mulher e mãe em tempos de pandemia?", o presente estudo convidou mulheres que são mães, em redes sociais virtuais, a partilhar um relato de suas experiências com a readaptação parental em função do distanciamento social causado pela pandemia de covid-19. O objetivo foi refletir sobre a experiência de ser mulher e mãe em tempos de covid-19 e distanciamento social, apontando algumas ressonâncias do cenário pandêmico na subjetividade dessas mulheres. O estudo teve como base o referencial psicanalítico, tanto na construção da pesquisa e análise dos relatos quanto na sua discussão. A análise dos cerca de 340 relatos coletados, os quais variaram de uma breve frase a longos parágrafos, apontou para uma série de questionamentos, pontos de análise e reflexões. A pandemia, e o decorrente distanciamento social, parece ter colocado uma lente de aumento sobre as angústias das mulheres que são mães, evidenciando sentimentos e sofrimentos sempre presentes. Destacaram-se, nos relatos, a sobrecarga das mulheres com as tarefas de cuidado dos filhos e da casa, a culpa, a solidão, a exaustão, e o sentimento de que não havia espaço nesse contexto para "ser mulher", sendo isso entendido especialmente a questões estéticas e de vaidade.(AU)

Starting from the question "How does it feel to be a woman and a mother in pandemic times?", this study invited women who are mothers, in virtual social networks, to share their experiences regarding parental adaptations due to social distancing caused by the COVID-19 pandemic. The objective was to reflect on the experience of being a woman and a mother in the context of COVID-19 and of social distancing, pointing out some resonances of the pandemic scenario in the subjectivity of these women. The study was based on the psychoanalytical framework, both in the construction of the research and analysis of the reports and in their discussion. The analysis of about 340 collected reports, which ranged from a brief sentence to long paragraphs, pointed to a series of questions, analysis topics, and reflections. The pandemic, and the resulting social distancing, seems to have placed a magnifying glass over the anguish of women who are mothers, showing ever-present feelings and suffering. The reports highlighted women's overload with child and house care tasks, the guilt, loneliness, exhaustion, and the feeling that there was no space in this context to "be a woman," and it extends to aesthetic and vanity related questions especially.(AU)

A partir de la pregunta "¿cómo te sientes siendo mujer y madre en tiempos de pandemia?", este estudio invitó por las redes sociales a mujeres que son madres a compartir un relato de sus experiencias sobre la readaptación parental en función del distanciamiento social causado por la pandemia del covid-19. Su objetivo fue reflexionar sobre la experiencia de ser mujer y madre en tiempos del covid-19 y el distanciamiento social, señalando algunas resonancias del escenario pandémico en la subjetividad de estas mujeres. Este estudio se basó en el marco psicoanalítico, tanto en la construcción de la investigación y análisis de los informes como en su discusión. El análisis de los casi 340 relatos, que variaron de una pequeña frase a largos párrafos, generó en las investigadoras una serie de cuestionamientos y reflexiones. La pandemia y el consecuente distanciamiento social parece haber agrandado las angustias de las mujeres que son madres, evidenciando sentimientos y sufrimientos siempre presentes. En los relatos destacan la sobrecarga de las mujeres con las tareas de cuidado de los hijos y del hogar, la culpa, la soledad, el cansancio, así como el sentimiento de que no hay espacio em este contexto para "ser mujer", relacionado principalmente a cuestiones estéticas y de vanidad.(AU)

Granos de polen anemófilos: sensibilización en pacientes alérgicos / Anemophilic pollen grains: sensitization in allergic patients

A nivel mundial, los aeroalérgenos más frecuentes causantes de enfermedades alérgicas son los granos de polen anemófilos. Estos han sido capaces de desencadenar crisis que han reflejado una elevada morbilidad. En Cuba los estudios de sensibilización a granos de polen han sido escasos. Con el objetivo de determinar la sensibilización a granos de polen en pacientes alérgicos y su relación con la presencia de enfermedades alérgicas, se realizó un estudio observacional descriptivo de corte transversal, no aleatorizado, de marzo a junio del 2019. La muestra se constituyó de 33 pacientes con asma, rinitis, rinoconjuntivitis alérgica, dermatitis atópica y conjuntivitis alérgica. A todos los pacientes se les realizó historia clínica alergológica y prueba cutánea por punción con extractos alergénicos de: Helianthus annus, Cosmos bipinnatus, Cynodon dactylon, Quercus sp, Eucaliptus sp. Se aplicaron las frecuencias absolutas, porcientos, desviación estándar, promedio, edad media y test de Spearman para su análisis. La edad media de la muestra fue de 36,9 años, con predominio de mujeres. Más del 50por ciento de los pacientes presentaron sensibilización a granos de polen; y de ellos, el 24,24por ciento resultaron polisensibilizados. El mayor porcentaje de sensibilización fue a Cynodon dactylon. La rinitis alérgica fue la enfermedad que prevaleció en la población estudiada(AU)

Nowadays, the most frequent aeroallergens causing allergy diseases have been anemophilous pollen grains. They have been able to triggers crises that have reflected a high morbidity. In Cuba, studies of sensitization to pollen grains have been scarce. The objective of our research was to determine the sensitization to pollen grains in allergic patients and its relationship with the presence of allergic diseases. A non-randomized, descriptive, cross-sectional, observational study was conducted from March to June 2019. The sample consisted of 33 patients with asthma, allergic rhinitis, rhinoconjunctivitis, atopic dermatitis and allergic conjunctivitis. All patients underwent allergic history and skin prick test testing with allergenic extracts of: Helianthus annus, Cosmos bipinnatus, Cynodon dactylon, Quercus sp, Eucalyptus sp. Absolute frequencies, percentages, standard deviation, mean, average age, and Spearman´s test were applied for analysis. The average age of the sample was 36.9 years, with a predominance of women. More than 50percent of the patients presented sensitization to pollen grains; of them, 24.24percent polysensitized. The highest percentage of sensitization was to Cynodon dactylon. Allergic rhinitis was the disease that prevailed in the population studied(AU)

HPV immunization in Brazil and proposals to increase adherence to vaccination campaigns / Imunização do HPV no Brasil e propostas para aumento da adesão à campanha de vacinação

ABSTRACT OBJECTIVES To identify the possible causes of low adherence to vaccination campaigns in Brazil, find and analyze campaigns regarding human papillomavirus (HPV) in Brazil and abroad, and apply quality tools to prepare proposals to increase vaccination coverage (VC) and prevent HPV in the country. METHOD This is a qualitative and deductive-hypothetical research. A narrative review of the literature (especially on the narratives and formats applied in vaccination campaigns in Brazil) was the technique used to develop our method. RESULTS Brazil had a 49.6% VC in 2019, unlike countries such as Australia (80.2% in 2017), Mexico (97.5% in 2019), and Peru (91% in 2019). This study found evidence of the use of social marketing strategies to engage communities as good practices in the vaccination campaigns of these countries. CONCLUSION With the retrieved information, three quality tools (Ishikawa diagram, Pareto graph, and 5W2H) classified and quantified the causes of low VC in Brazil and enabled proposals that can direct its Ministry of Health to take more effective strategies to achieve the HPV VC goal recommended by the WHO.

RESUMO OBJETIVOS Identificar as possíveis causas da baixa adesão à campanha de vacinação no Brasil, identificar e analisar as campanhas relacionadas ao papilomavírus humano (HPV) no Brasil e em outras regiões do mundo, e aplicar ferramentas de qualidade para elaboração de propostas para aumento da cobertura vacinal (CV) para prevenção do HPV no país. MÉTODO Pesquisa de natureza qualitativa e dedutiva-hipotética. A técnica utilizada para o desenvolvimento do método é a revisão narrativa da literatura, em particular estudando as narrativas e formatos aplicados nas campanhas de vacinação no Brasil. RESULTADOS Identificou-se que, em 2019, a CV no Brasil foi de 49,6%, diferentemente de países como Austrália (80,2% em 2017), México (97,5% em 2019) e Peru (91% em 2019). Evidências do uso de estratégias de marketing social para engajamento comunitário foram encontradas nas campanhas de vacinação utilizadas como boas práticas nesses países. CONCLUSÃO Com as informações encontradas foram aplicadas três ferramentas de qualidade (diagrama de Ishikawa, gráfico de Pareto e 5W2H) que classificaram e quantificaram as causas da baixa CV no Brasil e, com isso, viabilizaram propostas que podem direcionar o MS à tomada de estratégias mais eficazes para atingimento da meta de CV do HPV recomendada pela OMS.

Prevalence and underreporting of immunization errors in childhood vaccination: results of a household survey / Prevalencia y subregistro de errores de inmunización en la vacunación infantil: resultados de una encuesta de hogares / Prevalência e subnotificação de erros de imunização na vacinação de crianças: resultados de um inquérito domiciliar

ABSTRACT Objective: To investigate underreporting of immunization errors based on vaccination records from children under five years of age. Method: An epidemiological, cross-sectional analytical study, carried out through a household survey with 453 children aged 6 months to 4 years in three municipalities in Minas Gerais in 2021. A descriptive analysis was carried out, and the prevalence of the error was calculated per 100 thousand doses applied between 2016 and 2021. The magnitude was estimated of the association between variables by prevalence and 95% Confidence Intervals (95%CI). To analyze underreporting, State reporting records were used. Results: A prevalence of immunization errors was found to be 41.9/100,000 doses applied (95%CI:32.2 - 51.6). The highest prevalence occurred between 2020 (50.0/100,000 doses applied) and 2021 (78.6/100,000 doses applied). The most frequent error was an inadequate interval between vaccines (47.2%) associated with adsorbed diphtheria, tetanus and pertussis (DTP) vaccine (13.7/100,000) administration. Vaccination delay was related to immunization errors (7.55 95% CI:2.30 - 24.80), and the errors found were underreported. Conclusion: The high prevalence of underreported errors points to a worrying scenario, highlighting the importance of preventive measures.

RESUMEN Objetivo: Investigar el subregistro de errores de vacunación a partir de los registros de vacunación de niños menores de cinco años. Método: Estudio epidemiológico, analítico transversal, realizado mediante encuesta de hogares con 453 niños de 6 meses a 4 años en tres municipios de Minas Gerais en 2021. Análisis descriptivo y cálculo de la prevalencia de error por 100 mil dosis aplicadas entre 2016 y 2021. La magnitud de la asociación entre las variables se estimó mediante prevalencia e intervalos de confianza del 95% (IC95%). Para analizar el subregistro se utilizaron los registros de notificaciones estatales. Resultados: Se encontró una prevalencia de errores de inmunización de 41,9/100.000 dosis aplicadas (IC95%: 32,2 - 51,6). La prevalencia más alta se produjo entre 2020 (50,0/100.000 dosis aplicadas) y 2021 (78,6/100.000 dosis aplicadas). El error más frecuente fue un intervalo inadecuado entre vacunas (47,2%) asociado a la administración de la vacuna adsorbida contra la difteria, el tétanos y la tos ferina (DTP) (13,7/100.000). El retraso en la vacunación estuvo relacionado con errores de vacunación (7,55 IC 95%: 2,30 - 24,80), y los errores encontrados fueron subreportados. Conclusión: La alta prevalencia de errores no reportados apunta a un escenario preocupante, destacando la importancia de las medidas preventivas.

Conclusão: A alta prevalência de erros subnotificados aponta para um cenário preocupante, ressaltando a importância de medidas preventivas.

Orientação a pais por chamadas de áudio durante a pandemia de covid-19 / Support for parents via audio calls during the covid-19 pandemic / Orientación de los padres mediante llamadas de audio durante la pandemia de covid-19

O distanciamento social ocasionado pela pandemia de Covid-19 levou a profundas mudanças na rotina das famílias com crianças pequenas, aumentando o estresse no ambiente doméstico. Este estudo analisou a experiência de planejamento e implementação de um projeto de extensão universitária que ofereceu orientação a pais com filhos de 0 a 11 anos por meio de chamadas de áudio durante a pandemia. O protocolo de atendimento foi desenvolvido para atender às necessidades de famílias de baixa renda e listava problemas específicos relacionados ao confinamento em casa e ao fechamento das escolas seguidos por uma variedade de estratégias de enfrentamento. A análise de 223 queixas relatadas pelos usuários em 130 ligações revelou que 94% dos problemas referidos pelos pais foram contemplados pelo protocolo de atendimento e estavam relacionados aos problemas externalizantes (39%) ou internalizantes (26%) das crianças ou ao declínio do bem-estar subjetivo dos pais (29%). Serviços de apoio devem orientar os pais quanto ao uso de práticas responsivas e assertivas que promovam o bem-estar emocional da criança e estabeleçam expectativas comportamentais em contextos estressantes. A diminuição dos conflitos entre pais e filhos resultante do uso dessas estratégias tende a reduzir o sofrimento dos pais, aumentando sua sensação de bem-estar subjetivo. Recomenda-se ampla divulgação dessas iniciativas e seguimento dos casos.(AU)

The social distancing the COVID-19 pandemic entailed has led to profound changes in the routine of families with young children, increasing stress in the home environment. This study analyzed the experience of planning and implementing a university extension program that offered support to parents with children from 0 to 11 years old via audio calls during the COVID-19 pandemic. The service protocol was developed to meet the needs of low-income families and listed specific problems related to home confinement and school closure followed by a variety of coping strategies. The analysis of 223 complaints reported by users in 130 calls revealed that 94% of the problems reported by parents were addressed by the protocol and were related to children's externalizing (39%) or internalizing (26%) problems or to the decline in parents' subjective well-being (29%). Support services should guide parents on the use of responsive and assertive practices that promote the child's emotional well-being and set behavioral expectations in stressful contexts. The reduction in conflicts between parents and children resulting from the use of these strategies tends to reduce parents' suffering, increasing their sense of subjective well-being. Wide dissemination of these initiatives and case follow-up are recommended.(AU)

Modelling COVID-19 vaccination status and adherence to public health and social measures, Eastern Mediterranean Region and Algeria

Objective: To study the link between coronavirus disease 2019 (COVID-19) vaccination status and adherence to public health and social measures in Members of the Eastern Mediterranean Region and Algeria. Methods: We analysed two rounds of a large, cross-country, repeated cross-sectional mobile phone survey in June­July 2021 and October­November 2021. The rounds included 14 287 and 14 131 respondents, respectively, from 23 countries and territories. Questions covered knowledge, attitudes and practices around COVID-19, and demographic, employment, health and vaccination status. We used logit modelling to analyse the link between self-reported vaccination status and individuals' practice of mask wearing, physical distancing and handwashing. We used propensity score matching as a robustness check. Findings: Overall, vaccinated respondents (8766 respondents in round 2) were significantly more likely to adhere to preventive measures than those who were unvaccinated (5297 respondents in round 2). Odds ratios were 1.5 (95% confidence interval, CI: 1.3­1.8) for mask wearing; 1.5 (95% CI: 1.3­1.7) for physical distancing; and 1.2 (95% CI: 1.0­1.4) for handwashing. Similar results were found on analysing subsamples of low- and middle-income countries. However, in high-income countries, where vaccination coverage is high, there was no significant link between vaccination and preventive practices. The association between vaccination status and adherence to public health advice was sustained over time, even though self-reported vaccination coverage tripled over 5 months (19.4% to 62.3%; weighted percentages). Conclusion Individuals vaccinated against COVID-19 maintained their adherence to preventive health measures. Nevertheless, reinforcement of public health messages is important for the public's continued compliance with preventive measures.

Prévision de la séroprévalence de l'hépatite A dans la Wilaya de Setif en 2024 / Forecast of hepatitis a seroprevalence in the Wilaya of Setif in 2024

La séroprévalence des anticorps anti hépatite A (correspondant au taux d'immunisation) était de 100% à Sétif (Algérie), chez les personnes âgées entre 10 et 14 ans en 1986. Elle est passée à 70,4% en 2011. Partant de ce fait, les auteurs se proposent de prévoir cette séroprévalence, dans la même wilaya en 2024, à travers le modèle 'Logit binaire multiple', sur la base des données d'une enquête réalisée en 2011. La séroprévalence globale chez les sujets âgés entre 5 et 19 ans serait, selon les résultats de ce modèle, de 67% en 2024; les principaux facteurs associés à cette séroprévalence seraient l'âge, l'habitat, la taille des ménageset l'antécédent d'ictère. En conséquence, un programme de vaccination pourrait s'imposer comme une nouvelle stratégie de lutte contre la maladie dans la wilaya de Sétif.

The seroprevalence of anti-hepatitis A antibodies (corresponding to the immunization rate) was 100% in Sétif, in people aged between 10 and 14 years in 1986. It has declined to 70.4% in 2011. Starting from this fact, the authors propose to predict this seroprevalence, in the same wilaya (district) in 2024, through the 'multiple binary logit' model, based on data from a survey carried out in 2011. The overall seroprevalence in subjects aged between 5 and 19 years would be, according to the results of this model, 67% in 2024; the main factors associated with this seroprevalence would be age, habitat, household size and a history of jaundice. As a result, a vaccination program could establish itself as a new disease control strategy in Sétif.

Tends of "Zero-dose" children aged 12-23 months in Togo from 2000 to 2017 and predictions for 2030

Guided by the principle of leaving no one behind by improving equitable access and use of new and existing vaccines, the Immunization Agenda 2030 aims, among other things, to halve the incidence of "zero-dose" at the national level. This study aimed at studying the tends of the prevalence of "zerodose" children from 2000 to 2017 and making predictions for 2030. The study consisted of secondary data analyses from the Multiple Indicator Cluster Surveys (MICS) conducted in Togo. The study population consisted of children aged 12-23 months surveyed during MICS2 in 2000, MICS3 in 2006, MICS4 in 2010 and MICS6 in 2017. The dependent variable was the "zero-dose" vaccination status (1=Yes vs 0=No). The explanatory variables were related to the child, mother, household and environment. The study generated the overall annual percentage changes (APC) and by the independent variables. As a result, the prevalence of children with "zero-dose" expected for 2030 was estimated using Excel 2013 and Stata 16.0 software. In total, 636, 864, 916 and 952 children aged 12-23 months were included for MICS2, MICS3, MICS4 and MICS7, respectively. The prevalence of "zerodose" children decreased from 37.15% in 2000 to 31.72% in 2006, then 30.10% in 2010 and 26.86% in 2017, with an overall APC= - 1.89%. The highest relative annual decrease was from 2000 to 2006. If the historical rate of decrease remains unchanged, we predict that percentage of "zero-dose" children aged 12-23 months will be 20.96% in 2030, with a decrease of 22% compared to 2017, against a target of 50%. We suggest that strengthening strategies to increase full immunization coverage of children will contribute to reducing the percentage of zero dose children. A prerequisite will be a better understanding of the predictors of the "zero-dose" phenomenon in children

Knowledge, attitude and perception of mothers of under-five towards vaccination during supplementary immunization activities in Ibadan North-West Local Government Area, Ibadan, Oyo State, Nigeria

Supplementary immunization activities campaigns provide children with an additional dose of vaccine and deliver other interventions. However, there is dearth of information on knowledge, attitude and perception of mothers of under-five towards vaccination during supplementary immunization activities. A descriptive cross-sectional study which employed multistage sampling technique was designed to fill this gap. Four wards were randomly selected from eleven wards in Ibadan North-West Local Government Area and houses were enumerated from the selected wards, systematic random sampling was used to select houses and then respondents. A semi-structured interviewer administered questionnaire was used to elicit information on three hundred and five respondents. Knowledge scores of ≤4, 5-8, and ≥ 9 were rated poor, fair and good, respectively. Attitude scores of ≤5 and >5 was rated negative and positive attitude, respectively while perception scores ≤4 and >4 were rated negative and positive perception, respectively. Data was analyzed with SPSS version 25 using descriptive statistics and Chi-square test at 5% level of significance. The mean age of respondents was 30.6±6.1years, the highest level of education for most (68.5%) was secondary school. Their mean parity and number of under-five were 2.5±1.4 and 1.2±0.4, respectively. Knowledge was generally poor, more than half (53.1%) had poor knowledge, majority (88.2%) have positive attitude while 84.6% have a positive perception. One-fourth (24.6%) and one-fifth are of the opinion that frequent vaccination will make the vaccine ineffective and overload immune system, respectively. There was generally poor knowledge of supplementary immunizations and mothers need to be educated on the importance.

Impact of COVID-19 on the antenatal care services utilization in the region of Guelmim Oued Noun, Morocco

Background: Globally, the covid-19 pandemic has seriously impacted access to healthcare facilities across the world, although there is little evidence on how the pandemic affects the use of essential healthcare in the world. Objective: This study sought to evaluate the impact of the covid-19 pandemic on antenatal indicators in the region of Guelmim Oued Noun, Morocco. Methods: The aggregated data was delivered by regional health authorities covering the period from January 2017 to December 2020. The interrupted time series was mobilized to conduct statistical analysis. Results: The descriptive results revealed a steady decline after the Covid-19 pandemic in Antenatal indicators. The results of the regression model showed a negative impact of the pandemic on the antenatal recruitment rate (ß2 = - 16.14; p < 0.01), recruitment rate of women in antenatal visits the 1st quarter of pregnancy (ß2 = -2.09; p < 0.01), antenatal visit completion rate (ß2 = -18.10, p>0.05), average number of visits/pregnancies (ß2 = -15.65, p<0,05). Conclusion: The effect of the covid-19 pandemic on antenatal rates was significant for almost the indicators studied. Future studies should be focused on the impact of the pandemic on postnatal and immunization services on the national scale.

Preparation of chitosan hydrochloride stabilized emulsion and its immunostimulatory effect / 生物工程学报

In order to increase the ability of oil-emulsion adjuvant to stimulate cellular immunity, chitosan hydrochloride with positive charge was selected to stabilize oil-in-water emulsion (CHE). In this paper, model antigen ovalbumin was selected to prepare vaccines with emulsion adjuvant, commercial adjuvant or no adjuvant. The emulsion was characterized by measuring the particle size, electric potential and antigen adsorption rate. BALB/c mice were immunized by intramuscular injection. Serum antibody levels, the numbers of IL-4-secreting cells in splenocytes, cytotoxic T lymphocyte (CTL) response, and the expression of central memory T cells were measured to evaluate the immunostimulatory effect. The results showed that chitosan hydrochloride can effectively stabilize the emulsion. The emulsion size is about 600 nm, and the antigen adsorption rate is more than 90%. After immunization, CHE could increase serum antibodies levels and increase IL-4 secretion. Expression of CTL surface activation molecules was also increased to stimulate CTL response further and to increase the CD44+CD62L+ in T cells proportion. CHE as adjuvant can stimulate humoral and cellular immunity more efficiently, and is expected to extend the duration of protection.
