title: The recent evolution of the per capita income of the Brazilian states

description: ABSTRACT The purpose of this paper is to update the analysis of the process of convergence of state per capita incomes in Brazil, using new data for the period 1986-1995. Theil’s L and T indexes are used to show that the process of convergence, observed between 1970 and 1985 and reported in previous work, has come to a halt, since 1987. Some possible explanations for this result are also explored.

title: Chemical features of floodplain soils under different land-uses in the Solimões/Amazon River basin

description: ABSTRACT Most studies regarding the impacts of agricultural systems on soils of the Amazon region of Brazil have been carried out on upland soil, locally known as terra firme. Information regarding the impacts of different land-use systems on floodplain soil properties is still scarce. There is a need to broaden this knowledge to understand this Amazonian ecosystem better, especially how its soils respond to human interventions. This study aimed to describe the major chemical features of floodplain soils along the Solimões-Amazon Rivers and the effects of different land-use systems on soil nutrient levels. Sixty-two different land-use systems were sampled in 15 communities located in three different regions of the Solimões/Amazonas River floodplain complex: Upper and Middle Solimões (UMS), Lower Solimões and Middle Amazon (LSMA), and Lower Amazon (LA). Soils under cultivation showed a high availability of Ca2+, Mg2+, and P and low levels of exchangeable Al, in contrast to soils under forest and secondary vegetation, which were more acid and showed higher levels of exchangeable Al. Although most of the samples showed high contents of K+, for some areas, the low level (K+ &lt;0.15 cmolc kg-1) of this nutrient can become limiting to crop production. The low levels of N found in most of the analyzed samples confirm that this element may be the limiting nutrient for agriculture in floodplain ecosystems. The use of legumes and other nutrient-rich plants, which naturally occur in the Amazon floodplain environments, could potentially address this N deficiency in these soils.

title: Could Aspirin Treatment Modify the Assessment of the Uterine Arteries?

description: Abstract Objective To analyze whether acetylsalicylic (ASA) intake modifies the mean uterine arteries pulsatility index (UtA-PI) at the 2nd or 3rd trimester in a cohort of pregnant women with abnormal mean UtA-PI at between 11 and 14 weeks of gestation. Methods This is a retrospective cohort study. Singleton pregnancies with abnormal mean UtA-PI at between 11 and 14 weeks of gestation were studied. The participants were divided into 3 groups: 1) If the participant did not take ASA during pregnancy; 2) If the participant took ASA before 14 weeks of gestation; and 3) If the participant took ASA after 14 weeks of gestation. The mean UtA-PI was evaluated at the 2nd and 3rd trimesters, and it was considered to improve when it decreased below the 95th percentile. The prevalence ratio (PR) and the number needed to treat (NNT) werecalculated. Results A total of 72 participants with a mean UtA-PI&gt;95th percentile at the 1st trimester of gestation were evaluated. Out of the 18 participants who took ASA, 8 participants started it before 14 weeks of gestation and 10 after. A total of 33.3% of these participants had improved the mean UtA-PI at the 2nd and 3rd trimesters of gestation, although it was not statistically significant (p=0.154). The prevalence ratio was 0.95 (95% confidence interval [CI]: 0.31-1.89), but between the 1st and 2nd trimesters of gestation, the PR was 0.92 (95%CI: 0.21-0.99) and it was statistically significant. Conclusion The present work demonstrates a modification of the mean UtA-PI in participants who took ASA compared with those who did not. It is important to check if ASA can modify the normal limits of uterine arteries because this could have an impact on surveillance.

title: External pressure and commercial opening in Brazil

description: ABSTRACT This article discusses the influence of external pressure on the Brazilian trade liberalization process. The conditions under which external pressure is defined are based on the approach of international politics authors known as “realists” and related to the interests of the States, reliance on specific pressure instruments and vulnerability to pressure. Events such as the decline of the American hegemony, the rise of newly industrialized countries, the globalization of the international economy and the debt crisis, which led to an increase in international conflict during the l980’s are analysed, as well as domestic factors like the economic vulnerability of Brazil.

title: Wage differentials by gender and color: a comparison between Brazilian metropolitan regions

description: ABSTRACT The study analyses the wage differences behavior considering gender and race in the Brazilian metropolitan areas. Based on a sample from PNAD (1989) were empirically examined the pattern of the wage differences in the metropolitan areas in general and afterwards was made a regional comparison. Restressing previous researches, this paper reveals that, in average, either the men wages are higher than the women as well as those received by white people are superior than the blacks. Even after the realization a series of controls, such as: age, scholarship, place of living and race (gender). The gender differences revealed to be more homogeneous among the regions rather than the race differences.

title: Membranoproliferative glomerulonephritis: current histopathological classification, clinical profile, and kidney outcomes

description: Abstract Introduction: Membranoproliferative glomerulonephritis (MPGN) is a rare glomerular disease with a variable prognosis. A new classification based on the presence or absence of immunoglobulins and complement deposits in immunofluorescence microscopy (IF) of kidney biopsy has recently been proposed. The objectives of the study were to determine and compare the clinical, laboratory, and histopathological characteristics of those with primary or secondary MPGN, reclassify the primary ones based on IF findings, and evaluate kidney outcomes. Methods: This was an observational retrospective cohort study carried out in a single center (UNIFESP), based on the data collected from medical records of patients followed from 1996 to 2019. Results: Of 53 cases of MPGN, 36 (67.9%) were classified as primary and 17 (32.1%) as secondary MPGN. Most patients were hypertensive (84.9%) and had edema (88.7%) and anemia (84.9%); 33 (91.7%) patients classified as primary MPGN were reclassified as immune-complex-mediated and 3 (8.3%) as complement-mediated. The secondary MPGN group had hematuria more frequently (p &lt;0.001) and a higher prevalence of deposits of IgG (p = 0.02) and C1q (p = 0.003). Regarding the outcome, 39% of the patients achieved partial or complete remission. Lower initial serum albumin and higher initial 24-hour proteinuria were factors associated with worst renal prognosis. Conclusions: According to the new histological classification, the vast majority of MPGN cases were classified as being mediated by immune complexes. There were few differences between primary and secondary MPGN in relation to their clinical and laboratory characteristics.

title: Turnover and quality of employment in Brazil

description: ABSTRACT Several recent studies have shown that the main Brazilian market problem seems to be its low job quality level rather than lack of job creation. This article gathers new evidences on this topic, mostly on labor turnover. In fact, Brazil displays the highest labor turnover in the world for comparable measures. The paper also studies how a high labor turnover can partially explain the low quality of jobs observed in Brazil. The theoretical argument is that labor productivity depends essentially on the level of human capital, either general - through basic education - or specific - through on-the-job training. Since a high labor turnover is a disincentive for training investment, it lowers specific human capital and, therefore, labor productivity. Finally, some labor market legislation changes are proposed aiming at reducing labor turnover and increasing labor quality.

title: Nipple-sparing Mastectomy with Immediate Implant-based Reconstruction for Patients with Pure Ductal Carcinoma in Situ

description: Abstract Objective The presence of an extensive intraductal component is associated to an increasing risk of relapse in the nipple-areola complex. The aim of the present study was to evaluate the outcomes of patients diagnosed with ductal carcinoma in situ (DCIS) who underwent nipple-sparing mastectomy (NSM) with immediate breast reconstruction using silicone implants. Methods We retrospectively analyzed the postoperative complications and oncological safety of 67 breast cancer patients diagnosed with pure DCIS who underwent NSM with immediate breast reconstruction using silicone implants between 2004 and 2018. Results Among the 127 NSM procedures performed, 2 hematomas (1.5%) and 1 partial nipple necrosis (0.7%) were observed. After a mean follow-up of 60months, the local recurrence rate was of 8.9%, the disease-free survival rate was of 90%, and 1 of the patients died. Conclusion Despite the local recurrence rate, we showed that NSM with immediate breast reconstruction using silicone implants is a feasible surgical approach, with a low rate of complications and high survival rates for patients with a diagnosis of pure DCIS when breast-conserving surgery is not an option.

title: Clinical and demographic characteristics of adenomatoid odontogenic tumors: analysis of 116 new cases from a single center

description: Abstract Introduction The adenomatoid odontogenic tumor is a relatively uncommon odontogenic neoplasm representing about 4.7% of all odontogenic tumors. Objective The aim of this study was to determine the demographic and clinical profile of the adenomatoid odontogenic tumors in a Sri Lankan population. Methods Data gathered from the cases received for a period of 38 years from the Department of Oral Pathology, Faculty of Dental Sciences, University of Peradeniya. Request forms, biopsy reports and electronic data base of the department were used to obtain relevant information. Demographic data including age, gender and location of the tumor were included in the analysis. Results Out of 116 cases of adenomatoid odontogenic tumor, the mean age was 21.02 ± 11.24. It occurs more fre quently in the second decade of life, more prevalent in females, most often associated with the maxilla, predominantly affecting anterior jaw bones and presenting mostly in the right side of the jaw bone. The results from the present study showed the statistically significant relationship with site of occurrence (maxilla/mandible) and age (p&lt; 0.005). Further, depending on whether it occurs in anterior/mid/posterior site also showed a significant relationship with age (p≤ 0.001). However, side of occurrence, left or right or site of occurrence, showed no statistically significance with age (p&gt; 0.05). Conclusion Adenomatoid odontogenic tumor occurs more frequently in the second decade of life with a significant female predominance and the commonest site is anterior maxilla. This study revealed few differences on demographic and clinical presentations of adenomatoid odontogenic tumor from some regions of the world.
