Non-atrophic active chronic gastritis (ACG) is characterized by the presence of H. pylori in the gastric epithelium, known to be one of the first steps that precede progression to gastric adenocarcinoma. Inactive chronic gastritis (ICG) suggests that the patient has H. pylori gastritis, but this diagnosis is rarely made in routine histopathology. Clinical manifestations associated with H. pylori infection are potentially due to differences in virulence between strains;however, it is unclear if the progression of ACG to ICG depends on the H. pylori strain. The aim of this study was to compare the prevalence of the virulence factors of H. pylori found in patients with ACG and ICG, and its influence on the development of ICG. A significant association was observed between H. pylori detection by histological examination and the activity of gastritis (p 1 year) was reported by 28.6% of the ACG group and 42.5% of the ICG, while no evidence of association between long-term use of PPI and decreased inflammation was found in the patients studied. The genes cagA, cagE and virB11 were statistically associated with ACG (p = 0.01, p vacAs1 allele groups, ACG was associated with the most virulent group (p = 0.0015), while ICG was associated with the less virulent group (p < 0.001). The rate of co-infection was significantly higher in ICG than in ACG cases (p = 0.02). In conclusion, this study points to the role of virulent strains of H. pylori in the non-resolution of gastritis.

Purpose： to evaluate the in vitro influence of Copaiferalangsdorffii essential oil on the antinecrotic activity in macrophages, and on the antiapoptotic activity in macrophages and lymphocytes of Swiss mice. Methods： lymphocytes and macrophages were obtained from ten 60-day-old male mice weighing 42-45 g, and then cultured in 24-well plates. Cells were treated with concentrations of 2%, 5%, 10% and 20% of oil from Copaiferalangsdorffii before or after induction of apoptosis with ultraviolet light. We used positive and negative controls. Hoechst staining was performed, and then images of cells under fluorescence microscope were captured and digitalized. We used Image J_1.46o to quantify the fluorescence intensity/brightness of condensation of the chromatin ofapoptotic cells. We used one-way ANOVA with Bonferroni＇s and Tukey＇s multiple comparison tests. Results are expressed as the means of relative densities after adjustment and 95% confidence intervals; P 〈 0.05 was considered statistically significant. Results： oil from Copaiferalangsdorffii at different concentrations has decreased necrosis and apoptosis of both lymphocytes and macrophages from mice, when compared to C＋（all P 〈 0.05）. Discussion： Copaiferalangsdorffii is typically Brazilian and found in the Amazon region, with anti-inflammatory, antioxidant and antineoplastic effects due to its oil compounds, such as xyloglucans and kaurenoic acid. Its potential therapeutical usage was demonstrated in a national study. The present study showed that its oil has significant in vitro antiapoptotic and antinecrotic activity and it should be tested experimentally in vivo.

GTD (Gestational Trophoblastic Disease) is a pathology that encompasses benign and malignant clinical forms, affects women of childbearing age, has a variable incidence and is more frequent in developing or underdeveloped countries, colliding with the economic barrier. The frequent absence of clear protocols and guidelines for the correct diagnosis of the pathology results in inadequate classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to point out updated national and international practice protocols of diagnosis of GTD, through an integrative review. Seven articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized (usually one month for Partial Hydatidiform Mole six months for Complete Hydatidiform Mole and one year for Gestational Trophoblastic Neoplasia). Unfortunately, regarding the diagnosis of MH, the guidelines of some countries show the absence or difficulty of access to the karyotype test and ploid p57 or pelvic ultrasound accompanying the uterine curettage, contrary to what is proposed by the IFGO guideline. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of recurrence, morbidity and mortality, especially in less developed countries.

GTD (Gestational Trophoblastic Disease) is a pathology that encompasses benign and malignant clinical forms, affects women of childbearing age, has a variable incidence and is more frequent in developing or underdeveloped countries, colliding with the economic barrier. The frequent absence of clear protocols and guidelines for the correct diagnosis and treatment of the aforementioned pathology results in inadequate risk classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to compare the different national and international guidelines in the management of GTD, through an integrative review. Nine articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized;in low-risk GTN (Gestational Trophoblastic Neoplasm): chemotherapy with methotrexate or actinomycin D, in high-risk: EMA/CO protocol, in ultra-high-risk EMA/PE, methotrexate with radiotherapy for brain metastases. All medical societies recommend the registration of these patients in GTD screening centers, endorse the use of the IFGO scoring system (2000) and recommend the surgical management of placental site trophoblastic or epithelioid tumors, as chemotherapy is less effective in these cases. The controversies are in the proper follow-up after the treatment of HM, use of ultrasound to evacuate the uterus, administration of anti-D immunoglobulin, time of oxytocin infusion and rescue regimens that can be used in cases of resistant or recurrent GTN. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of
