Reação de laranjeiras Natal à aplicação de adubos minerais e orgânicos nas covas de plantio
Em solo Podzólico Vermelho Amarelo orto, da Estação Experimental de Mococa, foram estudados os efeitos de adubos orgânicos - torta de mamona, estêrco de curral e estêrco de aves - comparados com adubação mineral NP e NPK, todos aplicados em três doses, no desenvolvimento de laranjeiras. Medições efetuadas nos caules, a 10 cm acima do ponto de enxertia, no fim de cada estação do ano, revelaram efeitos positivos das adubações minerais com nitrogênio e fósforo, no desenvolvimento das plantas. A inclusão de potássio não provocou efeitos benéficos, sendo até prejudicial, confirmando resultados de trabalhos anteriores. Os adubos orgânicos não diferiram em seus efeitos e apresentaram melhor resultado quando aplicados na dose intermediária. Seu efeito foi, entretanto, inferior ao dos adubos minerais. O experimento permitiu verificar melhor desenvolvimento em plantas provenientes de mudas que possuíam originalmente 14 mm de diâmetro no viveiro, em comparação com as que possuiam 12 e 13 mm.

Capacidade fixadora de nitrogênio de Rhizobiumautóctone associado com soja perene e siratro, em dois solos do Estado de São Paulo
Com o objetivo de avaliar a fixação do nitrogênio atmosférico pela população de Rhizobium sp., que ocorre naturalmente nos solos do Estado de São Paulo e que se associa simbiòticamente com as leguminosas soja perene e siratro, foram conduzidos dois ensaios em vasos de Leonard. Os dados mostram que as populações de Rhizobium sp. presentes em Latossolo Roxo e Latossolo Vermelho Amarelo fase arenosa, sob vegetação natural de cerrado, não fixaram nitrogênio em quantidades comparáveis àquelas devidas à inoculação com estirpes puras. Verificou-se, ainda, influência altamente favorável do cultivo da soja perene na população de Rhizobium que se associa com siratro, presente no Latossolo Roxo.

Determinação de cobre, ferro, manganês e zinco, num mesmo extrato de planta, por potometria de chama de absorção
É apresentado um método de determinação, num mesmo extrato de planta, de ferro, manganês e zinco na fase aquosa, e de cobre, após sua extração em solvente orgânico. Para êsse estudo usou-se um analisador automático de absorção atômica Perkin-Elmer, modêlo 4A. Somente á silica, em certas concentrações, poderá constituir problema na determinação de manganês ou ferro, na ausência de cálcio. Na extração quantitativa do cobre é necessário conservar o pH abaixo de 2, para evitar interferência de ferro.

Teores de nitrogênio em fôlhas de cafeeiro, em relação à adubação química: I - Latossolo Roxo transição para Latossolo Vermelho Amarelo orto
Resultados de análises foliares obtidos durante cinco anos em ensaio de adubação química nitrogenada em café, cultivar Mundo Nôvo, instalado em Latossolo Roxo transição para Latossolo Vermelho Amarelo orto, revelaram, para amostras colhidas no verão, teores médios de 2,8% a 3% de nitrogênio total como indicativos de uma nutrição adequada. Produções elevadas de frutos estiveram associadas com teores da ordem de 500 ppm de nitrogênio nítrico nas fôlhas. A análise de fôlhas para ambas as formas de nitrogênio mostrou que a aplicação do adubo nitrogenado em pelo menos três parcelas, no período que vai de outubro a março, parece importante para prevenir a deficiência.

Estudo pedológico de três perfis da série Guamium
Tendo em vista um estudo genético da série Guamium, foram analisados três perfis de solo de Piracicaba, SP. A série Guamium é um Latossolo Vermelho Escuro orto, proveniente de um siltito do Grupo Tubarão, de origem glacial. Os perfis P1 e P2 apresentaram variações: a) nos teores de mica, os quais diminuem, da rocha para os horizontes superiores, de 28% a 2% no P1 e de 22% a 0% no P2; b) nos teores de caulinita, os quais aumentam, no mesmo sentido, de 54% a 87% no P1 e de 50% a 73% no P2; c) nos teores de gibbsita, os quais aumentam, no mesmo sentido, de 0% a C,6% no P1 e de 0% a 8,9% no P2; d) nos teores de alofana, os quais decrescem, no mesmo sentido, de 15% a 1,2% no P1 e de 22,5% a 14,0% no P2. O perfil P3 apresentou variação na composição mineralógica, em profundidade, não significativa, indício de que o seu material de origem foi previamente meteorizado e, ao ser transportado ao local que ocupa atualmente, foi homogenizado. Os perfis P1 e P2, ao contrário, provêm de um material de origem alterado in situ. Com base nos dados mineralógicos obtidos para os perfis P1 e P2 foi constatada a seguinte seqüência de meteorização: siltito -> caulinita e alofana -> gibbsita, que vem à ser a mesma encontrada na alteração de rochas básicas, rochas alcalinas, ardósia (de Brasília) e arenito Bauru.

INFLAMMATORY BOWEL DISEASE: IMPACT ON SCORES OF QUALITY OF LIFE, DEPRESSION AND ANXIETY IN PATIENTS ATTENDING A TERTIARY CARE CENTER IN BRAZIL
ABSTRACT BACKGROUND: Inflammatory bowel disease frequently affects patients at working age, compromising their quality of life in several levels: physical, psychological, familial and social. Few studies have evaluated the impact of Inflammatory bowel disease on quality of life, anxiety and depression in Brazilian patients. OBJECTIVE: Evaluate quality of life and its correlation with psychological aspects of patients with inflammatory bowel disease through the Inflammatory Bowel Disease Questionnaire and Hospital Anxiety and Depression Scale. METHODS: Cross-sectional study; Inflammatory Bowel Disease Questionnaire, Short Form-36 and Hospital Anxiety and Depression Scale were applied to consecutive outpatients in a tertiary referral center for inflammatory bowel disease. Harvey-Bradshaw Index and Truelove scores were used to evaluate Crohn’s disease and ulcerative colitis activity. Sample calculation: 113 patients for a significance level of 5%, power of 90% and a correlation coefficient of at least 0.3 between scales. Statistical analysis: Student-t test, Pearson and Spearman correlations. RESULTS: One hundred twenty patients participated in the study; mean age: 41.7 years; female: 58.3%; Crohn’s Disease: 69 patients. No low scores for quality of life were found across the four Inflammatory Bowel Disease Questionnaire domains; the Short Form-36 showed low scores in physical limitations (47.2±42.4) and emotional aspects (49.8±43.4); Hospital Anxiety and Depression Scale score presented a mean of 9.5±2.7 for anxiety and 8.7±2.0 for depression. Quality of life was decreased and Hospital Anxiety and Depression Scale did show increased indices of anxiety and depression, in both diseases only when clinically active. CONCLUSION: Inflammatory Bowel Disease Questionnaire and Hospital Anxiety and Depression Scale showed that outpatients of a tertiary care center for inflammatory bowel disease in Brazil presented good quality of life. The worst quality of life was associated with the intensity of the disease activity.

US-GUIDED PERCUTANEOUS CORE LIVER BIOPSY: ANALYSIS OF 171 CASES FROM A SINGLE ONCOLOGY SERVICE
ABSTRACT BACKGROUND: Though strongly suggestive of metastasis, focal lesions on liver scans of oncological patients require histological confirmation for the prescription of adequate treatment. OBJECTIVE: To evaluate the safety and efficacy of US-guided percutaneous core liver biopsy. METHODS: Descriptive, cross-sectional study based on secondary data from 171 patients submitted to US-guided percutaneous core liver biopsy at the diagnostic radiology service of the Ceará Cancer Institute (ICC, Brazil) between February 2010 and March 2015. Quantitative data were expressed in absolute numbers or percentages, with emphasis on the rate of complications observed within six hours after the procedure. RESULTS: The overall accuracy was 96.4%. The overall rate of complications was 2.3%, three quarters of which was due to hemorrhage. Age over 50 years was positively associated with accuracy. No deaths occurred within the period of observation. CONCLUSION: Our findings support the claim that the use of thick biopsy needles improves diagnostic accuracy. The few complications observed were non-lethal and predominantly hemorrhagic.

COMPARISON BETWEEN THE ENDOSCOPIC FINDINGS AND THE HISTOLOGICAL DIAGNOSIS OF ANTRAL GASTRITES
ABSTRACT BACKGROUND: Gastritis is a very common disorder that is widely distributed worldwide, representing one of the most prevalent pathological entities in Gastroenterology and Digestive Endoscopy. OBJECTIVE: This study aims to analyze the correlation between the endoscopic findings and the histological diagnosis of antral gastritis. METHODS: In this study, 92 reports of upper digestive endoscopy were performed between November 2014 and January 2015, including biopsy of the antral gastric mucosa, comparing the endoscopic and histological findings, which were classified according to the Sidney System. The 92 exams included 35 men and 57 women, ranging in age from 15 to 84 years. The most frequent indication was epigastric pain. RESULTS: Of the 92 examinations analyzed, the histological diagnosis of antral gastritis appeared in 75 exams, 59 endoscopic reports contained the diagnosis of antral gastritis, and 33 endoscopic findings were normal. The kappa coefficient was 0.212 (P<0.05), indicating that there was no significant agreement between the endoscopic findings and the histological diagnosis of antral gastritis. CONCLUSION: We conclude that histology represents the gold standard method for the diagnosis of antral gastritis and that in daily clinical practice, biopsies should always be performed, regardless of the endoscopic findings.

VITAMIN D DEFICIENCY AMONG INFLAMMATORYBOWEL DISEASE PATIENTS IN ARGENTINA: A CROSS-SECTIONAL STUDY
ABSTRACT BACKGROUND: An association has been established between low serum values of vitamin D and inflammatory bowel disease. There is a lack of evidence on whether this association is still observed in regions where sun exposure throughout the year is higher. OBJECTIVE: To compare the prevalence of vitamin D deficiency between inflammatory bowel disease patients and healthy controls. METHODS: Inflammatory bowel disease patients were consecutively enrolled as cases. Age and gender-matched healthy subjects who agreed to undertake a determination of serum vitamin D were enrolled as controls. Demographic features, medical treatment, need for hospital admission at diagnosis, steroid treatment, smoking, need for surgical treatment were evaluated as factors associated with vitamin D deficiency. RESULTS: Overall, 59 patients with a diagnosis of either Crohn’s disease or ulcerative colitis were enrolled, as well as 56 controls. Median age was 41 years (19-79) and 56% were male. Vitamin D deficiency was observed in 66.1% of inflammatory bowel disease patients versus 21.42% of healthy controls (OR 7.15 (3.1-16.48), P=0.001). Among inflammatory bowel disease patients, male gender, disease duration, moderate-to-severe disease and hospital admission at the moment of diagnosis were found to be associated with vitamin D deficiency. On multivariate analysis, only longer disease duration [(OR 1.01 (1-1.06)] and hospital admission at diagnosis [(OR 5.63 (1.01-31.61)] were found to be significantly associated with the latter. CONCLUSION: Vitamin D deficiency was more frequent among inflammatory bowel disease patients. Longer disease duration and need for hospital admission at diagnosis were associated to vitamin D deficiency among these patients.

USEFULNESS OF GASTRIC SUBMUCOSAL DISSECTION DEPTH TO EVALUATE SKILL ACQUIREMENT IN SHORT TERM TRAINING COURSES IN ESD: AN EXPERIMENTAL STUDY
ABSTRACT BACKGROUND: Endoscopic submucosal dissection (ESD) is a complex endoscopic procedure, with high rates of adverse events and technical difficulties. To overcome that problem, many training centers published the importance of animal models for skill acquirement in ESD. However, no study has used the submucosal dissection depth (DSUB) as a parameter to evaluate the learning curve in ESD, which might be a relevant factor since an optimal resection plane is important to achieve a curative resection and avoid intraoperative complications. OBJECTIVE: This study aimed to assess ESD skill acquirement after short-term training sessions by evaluating the submucosal dissection depth (DSUB) and the association with adverse events. METHODS: This experimental study included 25 experienced endoscopists in therapeuthic procedures (>5years) and 75 specimens resected by ESD (three resections / endoscopist). Learning parameters (resection time, size, en bloc resection rate, bleeding, perforation and submucosal dissection depth) were prospectively evaluated. The percentages of DSUB of all specimens resected were calculated. RESULTS: All specimens were resected from the gastric body (n=75). The mean size of the resected specimens was 23.97±7.2 mm. The number of adverse events, including bleeding, perforation, and death, were 17 (22.67%), 3 (4%), and 0 cases, respectively. The average mean time by the third dissection decreased from 28.44±9.73 to 18.72±8.81 min (P<0.001). The proportion of DSUB in the bleeding and non-bleeding group were respectively 37.97%±21.13% and 68.66%±23.99%, indicating a significant association between DSUB and bleeding incidence (P<0.001). The ROC curve analysis indicated a cut-off point of 61% (sensitivity, 64%; specificity, 94%) of submucosal dissection depth associated with bleeding. Therefore, when ESD was performed at a depth of >61% of the submucosal layer, the risk for bleeding during the procedure decreased (PPV, 0.97; 95% CI, 0.85-0.99). CONCLUSION: Improvement in the learning curve in ESD and a better cognitive ability were seen by the third dissection in these short term training courses. And a significant association between DSUB and the risk of bleeding.

PANCREATIC CANCER IN BRAZIL: MORTALITY TRENDS AND PROJECTIONS UNTIL 2029
ABSTRACT BACKGROUND: Pancreatic cancer is one of the main cancer-related causes of death in developed countries, and one of the most lethal malignant neoplasms. This type of cancer is classified as the ninth most frequent in the world. OBJECTIVE: Analyze temporal trends for pancreatic cancer in Brazil in the period 2000-2014 and calculate mortality projections for the period 2015-2029. METHODS: Ecological study, with temporal series, based on information provided by the Brazilian Mortality Information System. Analysis included deaths due to pancreatic malignant neoplasms in Brazil in the period 2000-2014, and analyzed according to sex, age group and Brazilian geographic regions. Projections were made until 2029 in five-year periods, calculated in Nordpred (within the R software). Mortality trends were analyzed by Joinpoint regression. RESULTS: Between 2000 and 2014, there were 112,533 deaths due to pancreatic cancer in Brazil. Age-standardised rates was 5.1 deaths/100,000 men and 3.81 deaths/100,000 women. The highest rates were registered for the Midwest region, for both genders. Projections indicated that for the five-year period 2025-2029 there will be increased mortality rates for men in the Northeast and Midwest regions. Joinpoint analysis for Brazil did not reveal significant increases for women (APC=0.4%; 95% CI: -0.2; 1.0), however, there was a significant increasing mortality trend for men (APC= 3.7%; 95% CI: 0.6-7.0) in the period 2000-2004, followed by a stable period, an then another period of significant increases after 2010. These figures are mostly explained by variations in the Brazilian demographic structure. CONCLUSION: Pancreatic cancer mortality is unequally distributed across Brazilian regions and genders, and during the next two decades the differences will be accentuated.

THE CHANGING TREND OF MORTALITY CAUSED BY GASTROINTESTINAL CANCERS IN IRAN DURING THE YEARS 2006-2010
ABSTRACT BACKGROUND: Cancers are one of the most important causes of death in the world. According to their high incidence and mortality, gastrointestinal cancers have particular importance among other cancers. OBJECTIVE: Therefore, this study was conducted to investigate the mortality change trends of gastrointestinal cancers in Iran. METHODS: This study was performed by analyzing the reported mortality data in 29 provinces of Iran in 2006-2010. Mortality trend of gastrointestinal cancers was drawn for both sexes in the study years and disaggregated by age groups and their frequency distribution. The WinPepi software was used for analysis. RESULTS: In the years 2006-2010, the mortality rate of, gastric, colorectal, liver and pancreatic cancers, has significantly increased. Totally, gastrointestinal mortality is higher in men than women. Also, the results showed that by increasing age, death from these cancers also increased. CONCLUSION: The most important causes of death from gastrointestinal cancers were gastric, liver and colorectal cancers in Iran and because of their increasing trend in the country, performing preventive interventions for the cancers’ risk factors is necessary.

IMPACT OF SMALL BOWEL CAPSULE ENDOSCOPY IN IRON DEFICIENCY ANEMIA: INFLUENCE OF PATIENT’SAGE ON DIAGNOSTIC YIELD
ABSTRACT BACKGROUND: Iron deficiency anemia remains one of the main indications to perform small bowel capsule endoscopy. Literature suggests that diagnostic yield is influenced by patient’s age but with conflicting results regarding age cutoff. OBJECTIVE: We aimed to clarify the differences in diagnostic yield and incidence of specific findings according to age. METHODS: Retrospective single-center study including 118 patients performing small bowel capsule endoscopy in the study of iron deficiency anemia. Videos were reviewed and small bowel findings that may account for anemia were reported. Incomplete examinations were excluded. Findings were compared between patients ≤60 and >60 years. RESULTS: Patients had a mean age of 58 years old (SD ±17.9) with 69.5% females (n=82). The overall diagnostic yield was 49% (58/118), being higher among patients >60 years (36/60, diagnostic yield 60%) than those ≤60 years (20/58, diagnostic yield 34%), (P<0.01). Angioectasias were more frequent in patients >60 years (45% vs 9%, P<0.01). Patients ≤60 years presented more frequently significant inflammation (Lewis score >135 in 10.3% vs 1.7%, P<0.05) and other non-vascular lesions (24% vs 10%, P=0.04). CONCLUSION: In our cohort small bowel capsule endoscopy diagnosed clinically relevant findings in the setting of iron deficiency anemia in almost half the patients. Diagnostic yield was higher in patients older than 60 years (60%), with vascular lesions being more frequent in this age group. Despite the lower diagnostic yield in patients ≤60 years, significant pathology was also found in this age group, mainly of inflammatory type.

CORRELATION BETWEEN NONALCOHOLIC FATTY LIVER DISEASE FEATURES AND LEVELS OF ADIPOKINES AND INFLAMMATORY CYTOKINES AMONG MORBIDLY OBESE INDIVIDUALS
ABSTRACT BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the commonest hepatopathy worldwide. OBJECTIVE: To investigate the correlations between NAFLD histopathological features and the levels of adipokines (adiponectin, leptin, and resistin) and circulating inflammatory markers (interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor alpha [TNF-α], and C-reactive protein [CRP]). METHODS: This is an exploratory cross-sectional study, which enrolled 19 women with obesity who underwent bariatric surgery. Biochemical characteristics evaluated included the levels of adiponectin, leptin, resistin, IL-6, IL-8, TNF-α, and CRP. NAFLD was assessed through histological examination of liver biopsies carried out during the surgical procedures. RESULTS: The mean age of the study group was 37.3±8.2 years old; mean BMI was 36.2±2.5 kg/m2. Among individuals with liver fibrosis, the levels of IL-8 were significantly higher (24.4 ± 9.7 versus 12.7 ± 6.6; P=0.016726). The intensity of fibrosis presented a significant negative correlation with the levels of adiponectin (R= -0.49379; P=0.03166); i.e. the higher the levels of adiponectin, the lower the intensity of fibrosis. The intensity of steatohepatitis presented a significant negative correlation with the levels of adiponectin (R= -0.562321; P=0.01221); this means that the higher the levels of adiponectin, the lower the intensity of steatohepatitis. CONCLUSION: Adiponectin levels were inversely correlated with the severity of fibrosis and steatohepatitis, whereas IL-8 levels were higher in individuals with liver fibrosis among individuals with obesity and NAFLD undergoing bariatric surgery. The use of these markers to assess NAFLD may bring significant information within similar populations.

ANALYSIS OF RISK FACTORS AND POSTOPERATIVE COMPLICATIONS IN PATIENTS WITH CROHN’S DISEASE
ABSTRACT BACKGROUND: The post-operative complications rate is greater in patients with Crohn’s disease than in other abdominal surgeries due to other benign conditions. Prevention and management of such complications are important factors in the care of these patients. OBJECTIVE: The objectives of this research are to analyze the rate of postoperative complications and the major risk factors in patients with Crohn’s disease. METHODS: A descriptive and retrospective study based on analysis of medical records of patients with Crohn’s disease undergoing ileal and/or colonic resection, which analyzed the main surgical complications and their major risk factors. RESULTS: Forty-four surgical procedures and thirty-seven patients were analyzed. Most were female (56.7%). Postoperative complications were observed in 18 (40.9%) surgeries. The disease duration (P=0.04), the penetrating behavior (P=0.013), the time between diagnosis and the first surgery (P=0.04), malnutrition with low body mass index (BMI), duration of surgery (P=0.016), and the size of the removed specimen (P=0.014) were associated with higher rates of complications. The use of drugs blocking tumor necrosis factor up to eight weeks before surgery was not significantly associated with higher complications rates or increased need for reoperation. CONCLUSION: The complication rate observed in this study is similar to published data. The duration of the disease, the penetrating behavior, the size of the removed specimen, the duration of the surgery, and BMI are important risk factors for perioperative complications in Crohn’s disease.

METACHRONOUS COLORECTAL LIVER METASTASES HAS BETTER PROGNOSIS - IS IT TRUE?
ABSTRACT BACKGROUND: Liver metastases from colorectal cancer are an important public health problem due to the increasing incidence of colorectal cancer worldwide. Synchronous colorectal liver metastasis has been associated with worse survival, but this prognosis is controversial. OBJECTIVE: The objective of this study was to evaluate the recurrence-free survival and overall survival between groups of patients with metachronous and synchronous colorectal hepatic metastasis. METHODS: This was a retrospective analysis of medical records of patients with colorectal liver metastases seen from 2013 to 2016, divided into a metachronous and a synchronous group. The Cox regression model and the Kaplan-Meier method with log-rank test were used to compare survival between groups. RESULTS: The mean recurrence-free survival was 9.75 months and 50% at 1 year in the metachronous group and 19.73 months and 63.3% at 1 year in the synchronous group. The mean overall survival was 20.00 months and 6.2% at 3 years in the metachronous group and 30.39 months and 31.6% at 3 years in the synchronous group. Patients with metachronous hepatic metastasis presented worse overall survival in multivariate analysis. The use of biological drugs combined with chemotherapy was related to the best overall survival prognosis. CONCLUSION: Metachronous colorectal hepatic metastasis was associated with a worse prognosis for overall survival. There was no difference in recurrence-free survival between metachronous and synchronous metastases.

ACUTE GASTROENTERITIS ASSOCIATED WITH NOROVIRUS GII.4 VARIANTS
ABSTRACT BACKGROUND: Norovirus (NoV) is an important etiologic agent of acute gastroenteritis and infects individuals of all ages, especially children in Brazil and worldwide. NoV GII.4 was the most prevalent genotype worldwide because of your extensive genetic diversity. In Brazil, especially in the Northeast, few studies have been developed for identify and molecularly characterize NoV. OBJECTIVE: The present study aimed to detect and describe the molecular epidemiology of NoV associated with acute gastroenteritis. METHODS: The viral RNA extracted from stool samples were subjected to Nested RT-PCR and the genotypes were determined by nucleotide sequences analysis. In total, 278 stool samples assisted at Aliança Hospital in the city of Salvador, with acute gastroenteritis were examined, between March 2009 and July 2012. RESULTS: A high NoV rate (54.2%) was identified in children under 5 years of age. We detected the circulation of different NoV GII.4 variants in Salvador, during the study period as Den Haag 2006b, New Orleans 2009 and Sydney 2012. CONCLUSION: These findings reinforce the need to study the molecular epidemiology of NoV infections in acute gastroenteritis.

HEPATITIS B AND C IN PREGNANT WOMEN ATTENDED BY A PRENATAL PROGRAM IN AN UNIVERSITARY HOSPITAL IN RIO DE JANEIRO, BRAZIL: RETROSPECTIVE STUDY OF SEROPREVALENCE SCREENING
ABSTRACT BACKGROUND: Hepatitis B and C are diseases with high morbimortality and constitute a global public health problem. In Brazil, the prevalence is not homogeneous, oscillating among different regions, but it is estimated that currently about 1% of the population present chronic disease related to the B virus and that there are 1.5 million infected with the C virus. Despite the development of hepatitis B vaccine, improvement in diagnostic methods and therapeutic advances in the field of viral hepatitis, there is still a large number of people who continues to be infected by these viruses, especially in populations at risk and also due to several factors, including vaccination and migration policies. Vertical and perinatal transmissions are of great importance in the epidemiology of viral hepatitis and the blood tests performed during prenatal care constitute a great opportunity for screening and identifying these viruses. OBJECTIVE: To evaluate the seroprevalence of markers for B and C viruses in women who underwent prenatal care at the Hospital Universitário Antônio Pedro (Antonio Pedro University Hospital) from 2006 to 2013 and to compare the results found with regional data and those described in the specific literature. METHODS: A descriptive, cross-sectional, quantitative study with retrospective data collected from 635 records of pregnant women attended at the Prenatal Service of the Hospital Universitário Antônio Pedro, Niterói, state of Rio de Janeiro, from March 2006 until December 2013. The database was built in the Microsoft Office Access program and was later exported to Microsoft Office Excel. For the processing and analysis of the data, it was used the SPSS (Statistical Package for Social Science, IBM) version 22.0, for Windows. RESULTS: Twelve cases with positive HBsAg (1.9%), 189 cases with positive anti-HBs (35.9%) and seven positive anti-HCV patients (1.3%) were observed. There was no significant association between age and positivity for HBsAg, anti-HBs and anti-HCV (P =0.205, 0.872 and 0.676, respectively). There was a direct relationship between the anti-HBs positivity and the last four years of the study (P<0.0001). CONCLUSION: A high prevalence of HBsAg was observed, higher than the expected for the evaluated region; there was a prevalence of anti-HCV, consistent with the current Brazilian reality; and a likely low rate of hepatitis B immunization, with a relatively high rate of susceptibility to this infection and no case of co-infection between B and C viruses and HIV. It is emphasized not only the need to trace hepatitis B and C, without exceptions, during prenatal care, since even though the current advances in therapy may not cure, at least they may allow a better quality of life for patients with chronic disease and the mandatory completion of immunoprophylaxis in all newborns. Special attention should be given to those patients susceptible to HBV, with prompt diagnosis and referral for specific vaccination.

INSULIN RESISTANCE REDUCTION AFTER SUSTAINED VIROLOGICAL RESPONSE WITH DIRECT ACTING ANTIVIRAL:NOT EVERY POPULATION IMPROVES
ABSTRACT BACKGROUND: Hepatitis C virus (HCV) infection is a serious public health problem, that affects approximately 170 million people worldwide. Chronic HCV infection is associated with hepatic insulin resistance and an increased risk of diabetes HCV-infected patients has been well documented. OBJECTIVE: To assess the homeostasis model assessment of insulin resistance (HOMA-IR) index in patients treated with direct acting antiviral (DAAs) medication in the sustained virological response (SVR), categorized by the presence or absence of cirrhosis. METHODS: A prospective study was conducted. Data were collected at the beginning of treatment (t-base) and in the twelfth week after the completion of treatment (t-SVR12). The inclusion criteria were presence of: HCV infection (RNA-HCV positive), age ≥18 years, completion of DAAs’ therapy, and presence of diabetes with use of oral hypoglycemic agents. All samples were collected during the study period. The exclusion criteria were: presence of HBV/HIV co-infection, hepatocellular carcinoma at baseline, diabetic patients taking insulin and transplanted patients (liver/kidney). Fibrosis was assessed by hepatic elastography or biopsy (METAVIR). Cirrhosis was determined by clinical results or imaging. HOMA-IR was calculated as fasting insulin (μU/mL) × fasting glucose (mmol/L)/22.5) The patients were divided into two groups: the general study population (all patients, including the diabetic patients) and the special population (patients with normal values of HOMA-IR, which is >2.5, and without diabetes). The delta HOMA-IR value was calculated as: HOMA-IR at t-base - HOMA-IR at t-SVR12. For the descriptive statistical analysis, the paired t-test and generalized linear model assuming the log binding function were performed. A P value of < 0.05 was considered significant. RESULTS: We included 150 patients, and 75 were cirrhotic. The mean age was 55.3±9.97 and body mass index was 27.4±5.18. Twenty-two (14.67%) were diabetic patients using oral hypoglycemic agents, and 17 (11%) were cirrhotic. In the general study population, the mean glucose and HOMA-IR values increased at t-SVR12, but insulin decreased. Delta HOMA-IR was negative at t-SVR12, but there was no significant difference. Excluding diabetic patients and those with normal HOMA-IR values (<2.5), mean glucose, insulin and HOMA-IR decreased at t-SVR12. Delta HOMA-IR decreased significantly at t-SVR12 (P: 0.02). CONCLUSION: In the general population, glucose and HOMA-IR values increased at t-SVR12, but insulin decreased. In the special population, glucose, insulin, HOMA-IR and Delta HOMA-IR decreased at t-SVR12.
