Irregular practices in drugstores in the offer of products for children under three years old / Práticas irregulares em drogarias na oferta de produtos para crianças menores de três anos

ABSTRACT Objective: To analyze the compliance with the commercialization of children's products included in the Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-Related Products (NBCAL) in drugstores in Uberlândia/MG. Methods: A cross-sectional study was carried out in 143 drugstores that sold infant products: infant formula (IF), follow-up IF, nipples, teats, pacifiers and nipple shields; FI for young children, transition foods and cereal-based foods, fluid or powdered milk, modified/similar milks of plant origin and dairy compounds. The location of drugstores in the five geographic sectors was performed by geoprocessing. The data collected were: types of promotion and types of drugstore administration (drugstore chains/drugstores with independent administration). Irregular commercial promotion was expressed as absolute and relative frequencies. Results: Irregular commercial promotion was found in 11.7% of nipples, pacifiers and bottles, in 10.0% of IF and follow-up formula, in 9.5% of IF for young children, in 11.1% fluid or powdered milk, in 25.0% of transition foods and cereal-based foods and in 59.1% of dairy compounds. In commercial drugstore chains, the presence of promotion for dairy (81.8 vs. 28.6%, respectively) was higher than in drugstores with independent administration. The opposite ocurred for fluid or powdered milk, modified and similar milks of plant origin. The downtown and eastern sectors had the highest percentages of promotions (26%). Conclusions: NBCAL violations still occur in drugstores, mainly in the sale of young children's foods and in the commercial network drugstores.

RESUMO Objetivo: Analisar a conformidade da comercialização dos produtos infantis incluídos na Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeira (NBCAL) e de compostos lácteos em drogarias de Uberlândia/MG. Métodos: Estudo transversal realizado em 143 drogarias que vendiam produtos infantis: fórmulas infantis (FI) para lactentes, FI de seguimento para lactentes, mamadeiras, bicos, chupetas e protetores de mamilo; FI para crianças de primeira infância, alimentos de transição e alimentos à base de cereais, leites fluidos/em pó, leites modificados/similares de origem vegetal e composto lácteo. A localização das drogarias nos cinco setores geográficos foi realizada por geoprocessamento. Os dados coletados foram: tipos de promoção comercial irregular e tipo de administração da drogaria (rede/independente). As promoções comerciais irregulares foram expressas em frequências absoluta e relativa. Resultados: Verificamos a presença de promoção comercial irregular em 11,7% dos bicos, chupetas e mamadeiras, em 10,0% das FI lactentes/seguimento de lactentes, em 9,5% das FI para crianças de primeira infância, em 11,1% dos leites, em 25,0% de alimentos de transição e em 59,1% dos compostos lácteos. Nas drogarias de rede, a presença de promoção comercial irregular foi maior para compostos lácteos (81,8 vs. 28,6%, respectivamente) e, para leites, foi maior nas drogarias independentes (30,8 vs. 6,0%). Os setores central e leste apresentaram os maiores percentuais de promoção comercial irregular (26%). Conclusões: As violações à NBCAL ainda ocorrem nas drogarias, principalmente para os produtos destinados às crianças de primeira infância, e nas drogarias de rede.

Performance and labor conditions of physiotherapists in Brazilian intensive care units during the COVID-19 pandemic. What did we learn?

OBJECTIVE: To describe the role of physiotherapists in assisting patients suspected to have or diagnosed with COVID-19 hospitalized in intensive care units in Brazil regarding technical training, working time, care practice, labor conditions and remuneration. METHODS: An analytical cross-sectional survey was carried out through an electronic questionnaire distributed to physiotherapists who worked in the care of patients with COVID-19 in Brazilian intensive care units. RESULTS: A total of 657 questionnaires were completed by physiotherapists from the five regions of the country, with 85.3% working in adult, 5.4% in neonatal, 5.3% in pediatric and 3.8% in mixed intensive care units (pediatric and neonatal). In intensive care units with a physiotherapists available 24 hours/day, physiotherapists worked more frequently (90.6%) in the assembly, titration, and monitoring of noninvasive ventilation (p = 0.001). Most intensive care units with 12-hour/day physiotherapists (25.8%) did not apply any protocol compared to intensive care units with 18-hour/day physiotherapy (9.9%) versus 24 hours/day (10.2%) (p = 0.032). Most of the respondents (51.0%) received remuneration 2 or 3 times the minimum wage, and only 25.1% received an additional payment for working with patients suspected to have or diagnosed with COVID-19; 85.7% of them did not experience a lack of personal protective equipment. CONCLUSION: Intensive care units with 24-hour/day physiotherapists had higher percentages of protocols and noninvasive ventilation for patients with COVID-19. The use of specific resources varied between the types of intensive care units and hospitals and in relation to the physiotherapists' labor conditions. This study showed that most professionals had little experience in intensive care and low wages.

RESUMO Objetivo: Descrever o papel dos fisioterapeutas na assistência a pacientes com suspeita ou diagnóstico da COVID-19 internados em unidades de terapia intensiva no Brasil em relação a: formação técnica, tempo de trabalho, prática assistencial, condições de trabalho e remuneração. Métodos: Foi realizado um inquérito transversal analítico com questionário eletrônico distribuído aos fisioterapeutas que atuavam no atendimento de pacientes com COVID-19 em unidades de terapia intensiva brasileiras. Resultados: Foram preenchidos 657 questionários por fisioterapeutas das cinco regiões do país, sendo que 85,3% trabalhavam em unidades de terapia intensiva adulto, 5,4% em neonatal, 5,3% em pediátrica e 3,8% em unidades de terapia intensiva mista (pediátrica e neonatal). Nas unidades de terapia intensiva com um fisioterapeuta disponível 24 horas por dia, os fisioterapeutas trabalharam com mais frequência (90,6%) na montagem, titulação e monitoramento da ventilação não invasiva (p = 0,001). A maioria das UTIs com fisioterapia 12 horas por dia (25,8%) não aplicou nenhum protocolo comparativamente às unidades de terapia intensiva com fisioterapia 18 horas por dia (9,9%) e às de 24 horas por dia (10,2%) (p = 0,032). A maioria dos entrevistados (51,0%) recebia remuneração de duas a três vezes o salário mínimo, e apenas 25,1% recebiam pagamento adicional por trabalhar com pacientes com suspeita ou diagnóstico da COVID-19; 85,7% deles não enfrentaram falta de Equipamentos de Proteção Individual. Conclusão: As unidades de terapia intensiva com fisioterapeutas 24 horas por dia apresentaram maiores porcentagens de protocolos e ventilação não invasiva para pacientes com COVID-19. A utilização de recursos específicos variou entre os tipos de unidades de terapia intensiva e hospitais e em relação às condições de trabalho dos fisioterapeutas. Este estudo mostrou que a maioria dos profissionais tinha pouca experiência em terapia intensiva e baixa remuneração.

Feeding Practices of Preterm Low Birthweight Infants Up to 6 Months: A Comparison Between Kangaroo and Conventional Care.

OBJECTIVE: The objective of this study is to compare feeding practices of low birthweight (LBW) infants, according to type of care received during and after hospital discharge: Kangaroo Care (KC) and Conventional Care (CC). METHODS: Prospective cohort study was conducted at a university hospital (Brazil) between 2019 and 2021. The sample consisted of 65 LBW infants (weight ≤ 1800 g)-46 in KC and 19 in CC. KC includes breastfeeding (BF) guidance and support to parents at hospital and after discharge. Data collection was performed at hospital discharge, and at the 4th and 6th month of corrected gestational age (CGA). Consumption of 27 foods was analyzed in the last 2 periods of the follow-up and expressed in relative frequency. Three indicators were analyzed: exclusive breastfeeding (EBF), mixed BF, and introduction of liquid and solid foods. RESULTS: Groups had similar health characteristics, except for the weight at hospital discharge and the Score for Neonatal Acute Physiology - Perinatal (SNAPPE II) score that were lower in KC group. We found higher frequency of EBF among KC at hospital discharge (CC = 5.3% vs KC = 47.8%; P = 0.001). The higher frequency of mixed BF was observed in KC at 4 months of CGA (CC = 5.6% vs KC = 35.0%; P = 0.023), and at 6 months of CGA (CC = 0.0% vs KC = 24.4%; P = 0.048). Consumption of solid foods (4th month of CGA = 25.9%, 6th month of CGA = 91.2%) and liquids (4th month of CGA = 77.6%, 6th month of CGA = 89.5%) were similar between groups. CONCLUSIONS: In KC, SNAPPE II scores were lower and frequency of EBF was higher at hospital discharge and frequency of mixed BF was higher over 6 months. Early supply of infant formula, liquid and solid foods were similar in both groups.

Association between phenotypic and genotypic characteristics and disease severity in individuals with cystic fibrosis / Associação entre as características fenotípicas, genotípicas e a gravidade da doença em indivíduos com fibrose cística

Abstract Objective: To analyze the association between phenotypic and genotypic characteristics and disease severity in individuals with cystic fibrosis treated at a reference center in Minas Gerais, Brazil. Methods: This is a retrospective study that collected clinical and laboratory data, respiratory and gastrointestinal manifestations, type of treatment, Shwachman-Kulczycki score, and mutations from the patients' medical records. Results: The sample included 50 participants aged one to 33 years, 50% of whom were female. Out of the one hundred alleles of the Cystic Fibrosis Transmembrane Conductance Regulator gene, the most prevalent mutations were DeltaF508 (45%) and S4X (18%). Mutation groups were only associated with pancreatic insufficiency (p=0.013) and not with disease severity (p=0.073). The latter presented an association with colonization by Pseudomonas aeruginosa and Staphylococcus aureus (p=0.007) and with underweight (p=0.036). Death was associated with age at diagnosis (p=0.016), respiratory symptomatology (p=0.013), colonization (p=0.024), underweight (p=0.017), and hospitalization (p=0.003). Conclusions: We could identify the association of mutations with pancreatic insufficiency; the association of Staphylococcus aureus colonization and underweight with disease severity; and the lack of association between mutations and disease severity. Environmental factors should be investigated more thoroughly since they seem to have an important effect on disease severity.

RESUMO Objetivo: Analisar a associação entre as características fenotípicas, genotípicas e a gravidade da doença em indivíduos com fibrose cística atendidos em um centro de referência de Minas Gerais, Brasil. Métodos: Trata-se de um estudo retrospectivo, em que os dados clínicos, laboratoriais, as manifestações respiratórias e gastrointestinais, o tipo de tratamento, o escore de Shwachman-Kulczycki e as mutações foram coletados dos prontuários de registros dos pacientes. Resultados: A amostra incluiu 50 participantes, de um a 33 anos de idade, sendo 50% do sexo feminino. Do total de cem alelos do gene Cystic Fibrosis Transmembrane Conductance Regulator, as mutações mais prevalentes foram Delta F508 (45%) e S4X (18%). Os grupos de mutações apresentaram associação somente (p=0,013) com a insuficiência pancreática e não com a gravidade da doença (p=0,073). Esta última apresentou associação com a colonização por Pseudomonas aeruginosa e Staphylococcus aureus (p=0,007) e com baixo peso (p=0,036). O óbito foi associado com a idade no diagnóstico (p=0,016), a sintomatologia respiratória (p=0,013), a colonização (p=0,024), o baixo peso (p=0,017) e a ocorrência de internação (p=0,003). Conclusões: Foi possível observar associação entre as mutações e a presença de insuficiência pancreática; entre a colonização por Staphylococcus aureus e o baixo peso com a gravidade da doença; e ausência de associação entre as mutações e a gravidade da doença. Os fatores ambientais merecem ser investigados mais detalhadamente, pois parecem apresentar impacto importante na gravidade da doença.

The possible mediating relationship promoted by the self-efficacy of breastfeeding associated with the Kangaroo Method on indicators of exclusive breastfeeding

Abstract Objective Assess the mediating role of breastfeeding self-efficacy in the association between the Kangaroo Neonatal Intermediate Care Unit and exclusive breastfeeding. Method Cross-sectional study nested in a cohort, carried out in the Neonatal Unit of a Brazilian university hospital between September 2018 and March 2020. The sample consisted of 114 newborns weighing ≤1800 g and their mothers who were divided into those who participated in the first and second stages of the Kangaroo Method and those who only passed through the first stage, categorized as the Conventional group. To assess the self-efficacy of breastfeeding, the Breastfeeding Self Efficacy Scale - Short-Form was used. The Mann-Whitney test was used to compare the breastfeeding self-efficacy score between the groups, and Fisher's exact test to compare rates of exclusive breastfeeding. The adjusted structural equation model was used to check for the mediating effect of breastfeeding self-efficacy. The significance level adopted was 5%. Results The kangaroo group had a higher rate of exclusive breastfeeding at hospital discharge (p= 0.000). There was a positive association between having remained in the kangaroo (p= 0.003) and the breastfeeding self-efficacy score (p= 0.025) with the rate of exclusive breastfeeding at hospital discharge. Breastfeeding self-efficacy did not act as a mediator. Conclusion The self-efficacy of breastfeeding and the stay of the low birth weight newborn baby in the kangaroo unit acted positively and independently in exclusive breastfeeding, and the self-efficacy of breastfeeding did not act as a mediator in this association.

Rise Time Perception, Phonological Processing, and Reading in Brazilian Portuguese-Speaking Schoolchildren.

BACKGROUND/AIMS: Studies of people with dyslexia have pointed to the ability to perceive the amplitude envelope rise time ("beat" perception) as a possible cause of phonological processing (PhP) difficulties in this population. However, there are very few studies about the relationships between such skills in the non-dyslexic school population. METHODS: We investigated the influence of the beat perception ability on PhP and reading skills of 93 Brazilian Portuguese-speaking schoolchildren from the 3rd to the 5th year, with data on reading, phonological awareness (PhA), lexical access, phonological operational memory, and perception of amplitude envelope rise time. To verify the possible effects of age, gender, and school grade on the tasks in the study, we directly included these variables in the models. RESULTS: Modeling structural equations showed that beat perception did not influence PhP or reading skills, but only the tasks of repetition of words and pseudowords. These tasks may be related because of the demand for phonological working memory necessary to perform the beat perception task rather than a possible connection between this and phonological abilities, as reported in the literature. CONCLUSION: We suspect beat perception could be of relevance only for subjects with altered reading and/or a deficit in PhP. Further studies will indicate whether the rise time of the amplitude envelope is an essential acoustic clue only for those individuals whose PhA ability is not fully present.

CHARCTERIZATION OF FEEDING OF CHILDREN UNDER 24 MONTHS IN UNITS CARED BY THE FAMILY HEALTH STRATEGY.

OBJECTIVE: To describe the median age of introduction and regular food intake by young children in units of the Family Health Strategy. METHODS: Cross-sectional study with 283 young children chosen by uniform stratified cluster sampling. Socio-demographic data on the mother and the child's food intake were collected (age of food introduction and weekly frequency). Foods were grouped into in natura/minimally processed (G1); culinary ingredients (G2); processed (G3) and ultra-processed (G4). The survival analysis was applied to define the median age of food introduction and the chi-square test was used to compare the frequency of food intake, according to the age range (0-5.9; 6-11.9; and 12-23.9 months old). RESULTS: The median duration of exclusive breastfeeding and breastfeeding were three and 19 months, respectively. The age of median food introduction of G1 was six months, except for eggs, milk and coffee (12 months). For oil and salt (G2), the median was 6 months, and for sugar (G2), seven months. The median age of introduction of most food of G4 was 12 months; for infant formulas, it was seven months; cookies and baby food, eight months. Most food had not yet been introduced for children under six months old. For children from six to 11.9 months old, the regular consumption of G4 (≥5 days/week) was higher for cookies (23.8%), bread (21.2%), infant formulas (21.2%) and baby food (35%); and for children from 12 to 23.9 months old, it was higher for cookies (31.2%), bread (57.5%) and baby food (48.7%). CONCLUSIONS: Food introduced and consumed on a regular basis was mainly in natura, at all ages. Processed and ultra-processed food presented a higher frequency of consumption after 12 months old.

Agreement between current status and retrospective data for prevalence and duration of exclusive breast feeding from low- and middle-income countries surveys.

BACKGROUND: Indicators to assess exclusive breast feeding (EBF) status are based on current status data according to World Health Organization (WHO), specially to avoid recall bias or imprecise reporting. OBJECTIVE: To analyse the agreement between current status and retrospective data for prevalence and duration of EBF in low- and middle-income countries. METHODS: Cross-sectional study using Demographic and Health Surveys (DHS) datasets of infants under six months from 10 low- and middle-income countries. It was applied two kinds of data about EBF: (1) current status data: variables about breast milk and foods offered in the previous day (yes or no) and (2) retrospective data: variables about age at which foods were offered the first time. The prevalence of EBF was estimated the same way for current status and for retrospective data. The median duration for current status data was calculated according to WHO recommendation, and retrospective data were calculated using survival analysis. The Kappa coefficient was applied to assess the agreement of prevalence using both kinds of data. RESULTS: Prevalence of EBF was higher using current status data and differences between both data ranged from 0.5 to 6.4 percentage points. Kappa coefficient ranged from 0.74 (substantial) to 0.94 (almost perfect) in nine countries. Medians were higher using retrospective than current status data for two countries and lower for another two; however, differences were small (from 0.08 to 0.44 month). For six countries, breast-feeding practice was so low that it was not possible to calculate the median using either data. CONCLUSIONS: The difference between prevalence and median estimated using current status and retrospective data is little and the agreement ranged to substantial and almost perfect. We suggest the use of retrospective data to estimate duration of EBF in cross-sectional surveys.

Sorption behaviors of antimicrobial and antiparasitic veterinary drugs on subtropical soils.

Brazil is one of the world's largest producers of animal protein, requiring the large-scale use of veterinary drugs. The administration of antimicrobials and antiparasitics is a common practice. However, there is a lack of information on how these drugs impact the environment. Antimicrobials are capable of altering the soil microbial population and are responsible for the development of multidrug-resistant microbial strains. Therefore, it is important to evaluate the fate and transport of these compounds in the environment, and one parameter used for this purpose is the soil-water partition coefficient. In this work, an assessment was made of the soil sorption behaviors of 18 drugs from seven different families, including antimicrobials (sulfonamides, fluoroquinolones, amphenicols, and macrolides) and antiparasitic drugs (milbemycin, avermectins, and benzimidazoles). Seven subtropical soils of different textural classes were tested. The Freundlich sorption coefficients, expressed as µg1-1/n (cm3)1/n g-1, were in the following ranges: 0.45 to 19 (sulfonamides), 72 to 2410 (fluoroquinolones), 9 to 58 (thiabendazole), 0.03 to 0.48 (florfenicol), 105 to 424 (moxidectin), 14 to 184 (avermectins), and 1.5 to 74 (macrolides). The results showed that the drugs belonging to the same family, with chemical structures in common, presented similar behaviors regarding sorption and desorption, for the different soils tested and are generally in agreement with soils from temperate regions. The data set obtained in this work give an overview of the fate of the veterinary drugs in Brazilian subtropical soils with different textures and composition and can be very helpful for exposure risk assessments.

Fate of ivermectin in the terrestrial and aquatic environment: mobility, degradation, and toxicity towards Daphnia similis.

Ivermectin (IVM) is a broad-spectrum antiparasitic drug that is regularly employed in veterinary medicine. In this work, the sorption and desorption of IVM in two Brazilian soils (N1-sand and S2-clay) as well as its leaching capacity, dissipation under aerobic conditions, and degradation in aqueous solution by photocatalysis with TiO2 in suspension were evaluated. The kinetic sorption curves of IVM were adjusted to a pseudo-second-order model. The sorption and desorption data were well fitted with the Freundlich isotherms in the log form (r > 0.96). The Freundlich sorption coefficient (K F (ads) ) and the Freundlich desorption coefficient (K F (des) ) were 77.7 and 120 µg(1-1/n) (cm(3))(1/n) g(-1) and 74.5 and 138 µg(1-1/n) (cm(3))(1/n) g(-1), for soils N1 and S2, respectively. A greater leaching capacity of IVM was observed for the sandy soil N1 than for the clay soil S2. Under aerobic conditions, the dissipation (DT50) at 19.3 °C was 15.5 days (soil N1) and 11.5 days (soil S2). Photocatalysis with UVC and TiO2 in suspension resulted in the degradation of 98 % of IVM (500 µg L(-1)) in water in 600 s. The toxicity (Daphnia similis) of the solutions submitted to the photocatalytic process was completely eliminated after 10 min.

[Low weight and functional disability in institutionalized elderly interns in Uberlândia in the State of Minas Gerais, Brazil]. / Baixo peso e dependência funcional em idosos institucionalizados de Uberlândia (MG), Brasil.

This article seeks to identify the association between nutritional status and functional dependence in institutionalized elderly interns in Uberlândia, Minas Gerais. It involved a cross-sectional study with 233 elderly interns in which sociodemographic variables, nutritional status and degree of dependency were assessed. Multivariate analysis was performed using Poisson regression with robust variance to assess the association between nutritional status and functional dependence of these senior citizens. Low weight by the Body Mass Index was associated with functional dependence after controlling for socioeconomic and demographic variables. The elderly with low weight had a prevalence ratio of dependence of 1.2 times the prevalence rate of dependence of well nourished elderly interns. As reported in the literature, age was also associated with dependence with a prevalence ratio of 1.19 for the longest living. Low weight is an important factor associated with functional disability. Thus, the need for evaluation, monitoring and recovery of nutritional status in the institutionalized elderly is stressed, as in addition to reducing morbidity and mortality from several diseases and improve quality of life, it can also prevent and delay functional dependency.

Foram avaliadas variáveis sociodemográficas, estado nutricional e o grau de dependência dos idosos. Realizou-se análise multivariada pela Regressão de Poisson com variância robusta, para verificar a associação entre o estado nutricional e dependência funcional. O baixo peso pelo Índice de Massa Corporal se associou à dependência funcional após controle para variáveis socioeconômicas e demográficas, os idosos com baixo peso tinham uma razão de prevalência de dependência de 1,20 vezes àquela dos eutróficos. Como bem reportado pela literatura, a idade também se associou à dependência, com razão de prevalência de 1,19, para os longevos. O baixo peso constituiu importante fator associado à incapacidade funcional. Dessa forma, ressalta-se a necessidade de avaliação, monitoramento e recuperação do estado nutricional de idosos institucionalizados, que além de reduzir morbimortalidade por diversas doenças e melhorar a qualidade de vida, ainda pode prevenir e retardar a dependência funcional.

This article seeks to identify the association between nutritional status and functional dependence in institutionalized elderly interns in Uberlândia, Minas Gerais. It involved a cross-sectional study with 233 elderly interns in which sociodemographic variables, nutritional status and degree of dependency were assessed. Multivariate analysis was performed using Poisson regression with robust variance to assess the association between nutritional status and functional dependence of these senior citizens. Low weight by the Body Mass Index was associated with functional dependence after controlling for socioeconomic and demographic variables. The elderly with low weight had a prevalence ratio of dependence of 1.2 times the prevalence rate of dependence of well nourished elderly interns. As reported in the literature, age was also associated with dependence with a prevalence ratio of 1.19 for the longest living. Low weight is an important factor associated with functional disability. Thus, the need for evaluation, monitoring and recovery of nutritional status in the institutionalized elderly is stressed, as in addition to reducing morbidity and mortality from several diseases and improve quality of life, it can also prevent and delay functional dependency.

OBJECTIVE: To evaluate the knowledge of public day care centers employees about breastfeeding and complementary feeding. METHODS: A cross-sectional study was conducted in 15 public day care centers randomly selected in the city of Uberlandia, Southeast Brazil. A questionnaire applied to school principals, teachers, educators and general services assistants (GSA) included demographic and socioeconomic variables and questions about knowledge on breastfeeding, complementary feeding besides employees' perceptions about these subjects. Kruskal-Wallis with multiple comparison and chi-square tests were used to compare variables by professional category. RESULTS: 304 employees participated in the study. The highest percentages of correct answers were noted for questions about exclusive breastfeeding: definition - 97% (n=296) and duration - 65% (n=199). Regarding complementary feeding, 61% (n=187) correctly answered about the appropriate age to introduce it, with a lower percentage for meat (56%; n=170) and sugar (16%; n=50). Concerning employees' perceptions, 9% (n=29) believed that there is weak breast milk, 79% (n=241) and 51% (n=157) reported the negative influence of bottle feeding and pacifier use on breastfeeding. Among the interviewed subjects, 77% (n=234) answered that they had a positive influence on the quality of the food given to the children. There were no differences in the answers according to professional category, except for the negative influence of pacifiers on breastfeeding. CONCLUSIONS: Employees of public day care centers knew more about breastfeeding than about complementary feeding. Educational activities about breastfeeding and complementary feeding are necessary for day care centers employees. .

Evaluation of liver regeneration by modulation with ischemic preconditioning after ischemia and reperfusion and partial hepatectomy.

OBJECTIVE: To evaluate liver regeneration modulated by ischemic preconditioning after ischemia, reperfusion and partial hepatectomy. METHODS: We used 24 Wistar rats of 12 weeks of age, which were randomly assigned into four groups: control (SHAM), hepatectomy (HEP), ischemia and reperfusion (IRG) and Ischemic Preconditioning (SRG). Analyses were made on liver enzymes ALT and AST, assessment of regeneration through the initial and final weight of the liver and the proliferation of hepatocytes by immunohistochemical analysis with Proliferating Cell Nuclear Antigen (PCNA). RESULTS: In all groups there was liver regeneration, with no statistically significant difference between them. There were significant differences in ALT and AST between groups HEP and SHAM, PRE and GIR, GIR and SHAM and PRE and SHAM (p <0.05). There were also significant differences in the PCNA labeling of the SHAM group as compared to other groups (p <0.05). CONCLUSION: The ischemic preconditioning decreased liver injury, but did not influence the regeneration up to 48 hours.
