Prevalence and underreporting of immunization errors in childhood vaccination: results of a household survey

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.

Performance indicators of Primary Care of the Previne Brasil Program

OBJECTIVE

to analyze the scope of the performance indicators of the Previne Brasil Program of Primary Health Care.

METHOD

an observational, descriptive study with a quantitative approach was carried out using secondary data, referring to the years 2020 and 2021, in the five Brazilian regions (North, Northeast, South, Southeast and Midwest), available in the Primary Health Care Information System. Descriptive statistics, relative frequencies and measures of central tendency and semiparametric modeling were used considering a 5% confidence interval.

RESULTS

there was evidence of evolution in the rates of performance indicators in most Brazilian regions in 2021, compared to 2020, however, the North and Midwest regions had incipient or negative rates, compared to the Southeast region. Despite the evolution in the rates of the indicators, few States managed to reach the goals established by the Ministry of Health for the strategic actions of prenatal care and women's health; and no state achieved the goal in strategic action on chronic diseases.

CONCLUSION

it is considered important to monitor the evolution of current indicators, envisioning their qualification so that they can evaluate primary health care and assistance, as well as guarantee the achievement of goals by ensuring funding for primary care actions.

Genomic and phenotypic features of Acinetobacter baumannii isolated from oil reservoirs reveal a novel subspecies specialized in degrading hazardous hydrocarbons

The genus Acinetobacter encompasses biotechnologically relevant species and nosocomial pathogens. In this study, nine isolates recovered from different oil reservoir samples showed the ability to grow with petroleum as the only carbon source and possessed the ability to emulsify kerosene. The whole genomes of the nine strains were sequenced and analyzed. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of all strains were compared to the reference strains, and the results were below the reference values (<97.88 and 82, respectively), suggesting that the isolates belong to a new subspecies of Acinetobacter baumannii. The name Acinetobacter baumannii oleum ficedula is proposed. A comparison of the whole genome repertoire of 290 Acinetobacter species indicated that the strains in this study resemble non-pathogenic Acinetobacter strains. However, the new isolates resemble A. baumannii when comparing virulence factors. The isolates in this study carry many genes involved in hydrocarbon degradation, indicating the potential to degrade most toxic compounds listed by environmental regulatory agencies such as ATSDR, EPA, and CONAMA. In addition, despite the absence of known biosurfactant or bioemulsifier genes, the strains showed emulsifying activity, suggesting the presence of new pathways or genes related to this process. This study investigated the genomic, phenotypic, and biochemical features of the novel environmental subspecies A. baumannii oleum ficedula, revealing their potential to degrade hydrocarbons and to produce biosurfactants or bioemulsifiers. Applying these environmental subspecies in bioaugmentation strategies sheds light on future approaches to bioremediation. The study shows the importance of genomic analysis of environmental strains and their inclusion in metabolic pathways databases, highlighting unique enzymes/alternative pathways for consuming hazardous hydrocarbons.

Factors related to the adoption of the Brazilian National Immunization Program Information System

Background

One way to optimize the adoption and use of technological innovations is to understand how those involved perceive, assess and decide to use them. This study aims to analyze the attributes that influence the adoption and use of the Brazilian National Immunization Program Information System (NIPIS) from the perspective of vaccination room workers.

Methods

This is a mixed method research, and a quantitative cross-sectional analytical study, with concomitant triangulation of data, carried out in a region of Brazil by using the Diffusion of Innovation Theory. We used a questionnaire with 183 nursing professionals who work at vaccination rooms in 12 municipalities. To test the research model, partial least squares structural equation modeling (PLS-SEM) and SmartPLS 2.3.0 have been applied to estimate the model. The qualitative research had a descriptive-exploratory character, using interviews (n = 18) analyzed through thematic analysis.

Results

The model proposed showed a mean correlation between the perceived attributes in the adoption and use of NIPIS. The results of the multiple regression indicated that the attributes “relative advantage” and “image” have a significant effect at 5% level (T > 1.97), positively influence the adoption and use of NIPIS; the attribute “voluntary use” negatively influences the adoption and use of the system; the attributes “experimentation”, “compatibility”, “profitability”, and “ease of use” did not influence the adoption and use of NIPIS. Emphasis has been placed on aspects that weaken the adoption and use of NIPIS such as lack of good quality internet and resistance to use the technology by some professionals. Workers perceive the importance of NIPIS for the municipality and point out that technological innovation provides data at an individual level, inserted in real time, which makes it possible to assess vaccination coverage. Lack of an unstable internet compromises data release due to system slowness.

Conclusions

The mixed method allowed an in-depth analysis of the adoption and use of NIPIS in the Western Health Macroregion of Minas Gerais State, and similarities were observed in the results. The attribute “relative advantage” is the one that most influences the adoption and use of NIPIS, which is the strongest predictor of innovation adoption rate.

Structural and procedural conditions in National Immunization Program Information System establishment

OBJECTIVES

to analyze structural and process conditions in National Immunization Program Information System establishment.

METHODS

a cross-sectional study conducted in 307 vaccination rooms in the state of Minas Gerais in 2017. For data collection, a multidimensional questionnaire was used. Descriptive data analysis was performed.

RESULTS

vaccination rooms have basic inputs necessary for System establishment. The greatest problems relate to professional practice. Low enrollment of population, failures in the active search for absentees, vaccine scheduling and absence of reports to monitor vaccination coverage were identified. Training was considered insufficient and ineffective.

CONCLUSIONS

Immunization Information System is an essential technological innovation for the management of immunization actions. However, the production of timely records and the use of information are still challenges. Investments in training are required to ensure System's management and operationalization activities.

National Immunization Program Information System: implementation context assessment

BACKGROUND

The National Immunization Program Information System (SIPNI - Sistema de Informação do Programa Nacional de Imunização) in Brazil is a technological innovation management tool that enhances the performance of managers and health professionals in the evaluation and monitoring of immunization activities. In the country, the decentralization of the System is at an advanced stage, but it still faces challenges regarding its operation and use, impacting on its results. This study aims to evaluate the deployment of SIPNI in the state of Minas Gerais, in 2017.

METHOD

Cross-section study performed in Primary Healthcare vaccination rooms in 54 municipalities in the Brazilian state of Minas Gerais, in 2017. A multidimensional questionnaire was used with nursing professionals who work in vaccination rooms, containing questions about the structure (presence of an internet-connected computer, instruction manual, software version, IT professional for technical support, trained healthcare professional, use of communication channels to obtain system information) and the process (activities performed by the staff to operate the immunization information system) of their work. Those questions refer to the components of the information system: system management, immunized-patient records, and Movement of Immunobiological. Implementation Degree (ID) was defined by a score system with different weights for each criterion, according to the importance level observed in it, with a rating of: adequate, partially adequate, inadequate and critically inadequate. For data analysis, median was used as the summary measure, and Pearson's Chi-Squared Test was used for proportion comparison.

RESULTS

Municipal SIPNI is not adequately implemented and that results mainly from the actions performed in health service units, indicating problems in the use of technology by professionals working in vaccination rooms. The structure was better evaluated than the process, presenting IDs of 70.9 and 59.5%, respectively. Insufficient internet access, inadequate use of communication channels, and lack of professional qualification were some of the identified structural issues. "Movement of Immunobiological" was the best-ranked component (ID = 68.5%), followed by "immunized patient records" (ID = 59.3%) and "SIPNI management" (ID = 50.7%). Partial performance of SIPNI is independent of population size in the municipality and of FSH coverage.

CONCLUSIONS

SIPNI is still an underutilized technological innovation. There are challenges that must be overcome, such as implementation of the final web version, internet connectivity, and capabilities aimed at the use of information generated by technology. Nevertheless, perspectives regarding SIPNI are positive, with functionalities to optimize activities in vaccination rooms.

Evaluation study of the National Immunization Program Information System

ABSTRACT Objective: To carry out the National Immunization Program Information System (SIPNI) accessability assessment (EA), considering the description of the intervention, the elaboration of the theoretical-logical model and the identification of the evaluative questions. Method: A single case study with a qualitative approach, based on the system of seven elements proposed by Thurston and Ramaliu (2005). The SIPNI and the context of analysis, the vaccination rooms, were defined as the case. Results: The SIPNI description, based on documents and scientific evidence, made it possible to understand its operationalization, the main events that characterize it. The theoretical-logical model visually and systematically configured the SIPNI organization with details of the inputs, activities, products and expected effects. The evaluative questions were evaluated and validated to evaluate the SIPNI. Final considerations: The SIPNI is evaluable and presented a favorable scenario for its development. EA is an important strategy for planning subsequent evaluations, maximizing their potentials.

Prevalence of Hepatitis B and C virus infection among alcoholic individuals: importance of screening and vaccination

Drug users have been reported to have an increased risk for acquisition of viral hepatitis. This study aims to evaluate the prevalence of HBV and HCV infection and usefulness of saliva for HBsAg and anti-HCV detection in alcoholic patients.A total of 90 alcoholic patients were recruited in 2013. HBsAg and anti-HCV were tested in serum and saliva, anti-HBc and anti-HBs were tested in serum using commercial enzyme immunoassays (EIA).Using serum samples, anti-HCV, HBsAg, anti-HBc and anti-HBs prevalences were 5.6%, 0%, 15.7%, and 29.2%. HBsAg detection in saliva showed 100% of specificity and anti-HCV detection demonstrated 100% of sensitivity and 94.7% of specificity. Low prevalence of HBV and high prevalence of anti-HCV were found and reinforced the recommendation of HBV vaccination to avoid the acute and chronic cases and HCV screening in this group to identify cases for antiviral therapy. Saliva samples could be used for anti-HCV detection in this population, what could increase the diagnosis access.

PERCEPÇÃO DE EQUIPE DE ENFERMAGEM SOBRE ESPIRITUALIDADE NOS CUIDADOS DE FINAL DE VIDA

O objetivo do estudo foi investigar a percepção da equipe de enfermagem acerca da espiritualidade nos cuidados de final de vida. Trata-se de estudo qualitativo descritivo, realizado com 20 profissionais de enfermagem de um hospital da região Centro-Oeste de Minas Gerais. A coleta de dados ocorreu no período de maio a junho de 2014 no setor de oncologia, por meio de um questionário semiestruturado. Os dados foram analisados na técnica de análise de conteúdo. Os resultados apontam que, embora a equipe de enfermagem tenha boa aceitação da morte, a espiritualidade é pouco abordada e ainda existe despreparo para abordar este aspecto na assistência ao paciente em fase final de vida. Com base nesses achados, torna-se necessária a inclusão do tema nos currículos das instituições de nível superior e técnico em enfermagem e ainda mais estudos na área, como forma de sensibilização e capacitação dos profissionais.

Physiological strain to prolonged exercise bouts at the walk-run transition speeds depends on locomotion mode in healthy untrained men

This study compared the physiological strain induced by prolonged walking and running performed at the walk-run transition speed (WRTS) in healthy untrained men. Twenty volunteers (age: 28 ± 5.01 years; height: 174.0 ± 0.3 cm; body mass: 74.5 ± 0.6 kg) underwent the following: (a) ramp-incremental maximal cardiopulmonary exercise test (CPET); (b) specific protocol to detect the WRTS; and (c) two 30-min walking and running bouts at WRTS (mean ± SD: 6.9 ± 0.06 km/h). Expired gases were collected during exercise bouts via the metabolic cart. A significant effect of locomotion mode (F = 4.8, P < 0.001) was observed with running resulting in higher cardiorespiratory responses than walking at the WRTS (oxygen uptake: mean difference = 0.26 L/min; pulmonary ventilation: mean difference = 5.53 L/min; carbon dioxide output: mean difference = 0.32 L/min; heart rate: mean difference = 13 beats/min; total energy expenditure: mean difference = 59 kcal). The rating of perceived exertion was similar across locomotion modes (mean difference = 0.3; P = 0.490). In conclusion, running promoted greater cardiorespiratory responses than walking at the WRTS in untrained healthy men. These data might have practical impact on aerobic training performed at intensities corresponding to WRTS.

Structural polymorphism of the mannose-binding lectin 2 (MBL2 ) gene in HCV-infected patients with a serological marker for thyroid autoimmunity

We studied the association of the mannose-binding lectin-2 (MBL2) polymorphism with anti-thyroid antibodies (ATA) in hepatitis C virus (HCV)-infected Brazilian patients (n = 162) and 124 healthy volunteers screened for ATA. Our results showed that patients with ATA had higher frequency of genotype 00 than controls. MBL may play a role as disease modifier in HCV infection.
