Analysis of vaccine loss due to temperature change.

OBJECTIVES: to analyze vaccine losses in a Health Region in the Northwest of São Paulo. METHODS: retrospective cross-sectional study with secondary data obtained from Temperature Change Notification Forms used by the Epidemiological Surveillance Group XXIX of São José do Rio Preto between 2010 and 2017. Descriptive and inferential analysis were performed using multiple linear regression and significance level of 95%. RESULTS: in total, 341 notifications of temperature changes were analyzed, of which 70.1% were caused by structural reasons, 57.8% in industrial refrigerators and 91.2% in primary care services. Of the doses that suffered a change in temperature, 41.4% were lost and 58.6% were administered to the population. The highest percentage of lost doses compared to those applied occurred in smaller municipalities, although they reported less. CONCLUSIONS: nursing workers who work in vaccination rooms should make efforts to prevent temperature changes and avoid losses and higher public expenses.

Effectiveness Analysis of the Immunization Against Hepatitis B in Liver Transplantation Patients.

OBJECTIVE: This article analyzes the effectiveness of a super-accelerated immunization schedule against hepatitis B in patients who have received a liver transplantation. METHODS: This is a quantitative and retrospective study based on secondary data of medical records from 177 patients who have received a liver transplantation at the Hospital de Base in São José do Rio Preto, São Paulo State, Brazil, between 1998 and 2016. RESULTS: From the total number of participants, 72.89% were male, 39.55% had a cirrhosis diagnosis with associated causes, 23.16% had hepatocellular carcinoma, 53.11% were classified according to Child-Turcotte-Pugh C score, 58.76% had the hepatitis C virus, 97.18% had received an unconventional immunization schedule, and seroconversion was 36.63% among those with an unconventional schedule. The fact that the patient had the hepatitis C virus was statistically significant considering the lack of protection of the vaccine against the hepatitis B virus; their chances were 5 times higher of not seroconverting at the end of the immunization schedule. CONCLUSION: The need for high immediate protection in a short term may justify using unconventional immunization schedules in patients who make it to the transplantation waiting list without any previous immunization.

NEW IMMUNIZATION SCHEDULE EFFECTIVENESS AGAINST HEPATITIS B IN LIVER TRANSPLANTATION PATIENTS.

BACKGROUND: Although liver transplantation is considered to be a high-risk procedure, it is well-established as a treatment option for the cure and quality of life enhancement for individuals who suffer from diseases. Preventing an infection by hepatitis B virus through immunization schedules has been the most effective way to reduce complications, since it decreases the number of people who suffer from chronic hepatitis caused by the hepatitis B virus and eradicates its transmission. OBJECTIVE: 1. Analyzing evidence in the literature on various schedules employed for immunization against hepatitis B in patients who have received a liver transplantation. 2. Suggesting potential immunization schedules against hepatitis B in patients who suffer from liver cirrhosis, without previous verifying documentation, using the Child-Turcotte Pugh score, according to evidences found in the literature. METHODS: Systematic review of the literature, conducted on the data bases MedLine, PubMed, and Lilacs, between September, 2017 and January, 2018, by using the following keywords: "Liver Transplantation, "Immunization Schedule", "Hepatitis B Vaccines". In order to analyze the articles, a summary figure was especially designed and both the results and discussion were presented in a descriptive way. RESULTS: We included 24 studies; among them, eight had accelerated immunization schedules, 13 followed the conventional schedules, and three had super accelerated schedules. Regarding immunization, 21 studies were conducted with patients in the pre-transplant period, one with a transplanted patient, one with a pre-transplant group, and one with a post-transplant group. Found articles suggest that, disregarding the chosen immunization schedule, seroconversion rates tended to be lower as the liver disease advanced, compared to the healthy population. CONCLUSION: The studies did not find seroconversion superiority between the different immunization schedules (conventional and unconventional). However, since candidates to liver transplantation are usually very vulnerable, results show that super accelerated immunization schedules are possibly recommended for such group of patients; serologic test results will be higher when the immunization schedule is completed in the pre-transplant period.

RESUMO CONTEXTO: O transplante de fígado, apesar de ser um procedimento de elevado risco, está consolidado como recurso terapêutico para cura e melhoria da qualidade de vida de indivíduos acometidos por doenças. A prevenção da infecção pelo vírus da hepatite B através da vacinação tem sido a medida mais efetiva para reduzir complicações, diminuindo o número de pessoas com hepatite crônica pelo vírus da hepatite B e eliminando a transmissão. OBJETIVO: 1. Analisar as evidências na literatura sobre os diferentes esquemas utilizados para a vacina contra a hepatite B em pacientes submetidos a transplante de fígado. 2. Sugerir possíveis esquemas de vacinação contra hepatite B para pacientes com cirrose hepática, sem documentação comprovatória anterior, em relação à classificação de Child-Turcotte Pugh, segundo evidências encontradas na literatura. MÉTODOS: Revisão sistemática da literatura, realizada nas bases de dados MedLine, PubMed e Lilacs, no período de setembro/2017 a janeiro/2018, com as seguintes palavras chaves: "Liver Transplantation, "Immunization Schedule", "Hepatitis B Vaccines". Para análise dos artigos foi utilizado um quadro sinóptico especialmente construído para esse fim e a apresentação dos resultados e discussão foi feita de forma descritiva. RESULTADOS: Foram incluídos 24 estudos, sendo oito com esquemas vacinais acelerados, 13 com esquemas convencionais e três com esquemas super acelerado. Quanto ao período da vacinação, 21 estudos foram realizados com pacientes no período pré-transplante, um em pacientes transplantados e um com um grupo pré e um grupo pós transplante. Os artigos encontrados sugerem que independente do esquema vacinal escolhido, as taxas de soroconversão tendem a ser menores conforme o avançar da doença hepática, em relação à população saudável. CONCLUSÃO: Os estudos não encontraram superioridade de soroconversão entre os diferentes esquemas de vacinação (convencional e não convencional). Entretanto, sabendo da vulnerabilidade que os candidatos a transplante de fígado estão expostos, os resultados demonstram que o esquema de vacinação superacelerado pode ser indicado para este grupo de pacientes, e que os resultados sorológicos são mais elevados quando o esquema de vacinação é completado no período pré-transplante.

Recidiva da Tuberculose: fatores associados em um Grupo de Vigilância Epidemiológica de São Paulo / Tuberculosis Recurrence: Associated Factors in an Epidemiological Surveillance Group of São Paulo

Analisar os fatores associados aos casos de recidiva de tuberculose (TB) em notificações no Grupo de Vigilância Epidemiológica XXIX/São José doRio Preto/SP. Trata-se de um estudo caso-controle, analisando as notificações de TB pulmonar no período de 1996 a 2014. Considerou-se caso notificações de ͞Recidiva͟ e controle: notificações classificadas como caso ͞Novo͟ e cujo desfecho foi ͞Cura͟. Utilizou-se para a análise dos dados o odds ratio e análise multivariada com intervalo de confiança de 95%. As variáveis sexo e desfecho desfavorável no 7º mês permaneceram significativamente associadas à recidiva. O sexo masculino apresentou 1,8 vezes maior risco (p=0,0551) e os indivíduos que obtiveram desfecho desfavorável no 7º mês de tratamento apresentaram 4,6 vezes mais chance de ter recidiva (p=0,0000). Foram encontrados dois fatores associados à recidiva: o sexo masculino e o desfecho desfavorável do tratamento, o que mostra a necessidade de avaliar a qualidade da assistência prestada.

Analyze the factors related to cases of tuberculosis (TB) recurrence in reports of the Epidemiological Surveillance Group XXIX/São José do Rio Preto/SP. This is a case-control study that analyzes pulmonary TB reports in the period between 1996 and 2014. Cases were reports of ͞Recurrence" and control: reports classified as "New" case and with "Healed" outcome. Odds ratio and multivariate analysis with 95% confidence interval were used to analyze the data. The variables of gender and adverse outcome in the 7th month remained significantly associated with recurrence. Males showed 1.8 times greater risk (p = 0.0551) and individuals who obtained an adverse outcome in the 7thmonth of treatment were 4.6 times more likely to recur (p = 0.0000). We found two factors associated with recurrence: male gender and adverse treatment outcome, which shows the need to assess the quality of the care provided.

Procedimentos inadequados em sala de vacina: a realidade da região de São José do Rio Preto / Inadequate procedures in vaccination rooms: the reality in the region of São José do Rio Preto

Analisar as notificações de procedimentos inadequados em salas de vacina do Grupo de Vigilância Epidemiológica – GVE XXIX São José do Rio Preto e relacionar com as capacitações realizadas em sala de vacina. Estudo descritivo, exploratório,quantitativo, com 32 notificações categorizadas em: notificante, imunobiológico, profissional, usuário e finalização do caso. A maioria das notificações (68,7%) foi proveniente de unidades básicas de saúde. Dentre os imunobiológicos relacionados, 37,5% foram associados com as vacinas contra influenza A H1N1; em relação à ocasião do procedimento inadequado, 46,9% ocorreram durante as atividades derotina, 46,9% executados por auxiliares de enfermagem; 71,9% dos profissionaisparticiparam de capacitações em sala de vacina; 62,5% atuavam em sala de vacina entre 01 e 10 anos. Dentre os usuários que sofreram as inadequações de procedimentos, 46,9% tinham de 1 a 10 anos; 3,1% apresentaram algum sintoma, e todos evoluiram para cura. Em 2009 foram realizadas duas capacitações atingindo 71,2% dos municípios da região. Procedimentos inadequados durante a aplicação devacinas são possíveis de ocorrer e o seu conhecimento torna-se importante para oaperfeiçoamento das capacitações com vistas à redução dos mesmos. Artigos sobre o assunto são escassos, apesar do relato de falhas na administração de medicamentos. A subnotificação merece planejamento de melhorias
