title: Selectivity and Effectiveness of Herbicides in the Grain Sorghum Crop

description: ABSTRACT: Over the years, cultivated areas of sorghum have expanded considerably in Brazil. Chemical weed control has become an obstacle due to the scarcity of herbicides registered for the crop. The aim of this study was to evaluate the efficiency of weed control and selectivity of herbicides applied in pre and post emergence in the crop. Two experiments were conducted. In one of them, the hybrid BRS 310 was used while DKB 550 was used in the other. The experiments were performed in the field in randomized block design, evaluating seven treatments with four replications. The used treatments were: 1. Hand weeding, 2. S-metolachlor (1,440 g a.i. ha-1), 3. S-metolachlor (1,440 g a.i. ha-1) + atrazine (2,000 g a.i. ha-1), 4. atrazine (2,000 g a.i. ha-1), 5. atrazine (3,000 g a.i. ha-1), 6. atrazine (2,000 g a.i. ha-1) + mineral oil (0.25%), and 7. atrazine (2,000 g a.i. ha-1) + mineral oil (0.5%). It was verified that post-emergence atrazine was efficient in the weed control and selective to the sorghum crop, not affecting productivity, except in mixture with mineral oil (0.5%). S-metolachlor cannot be recommended in pre-emergence for the tested cultivars because it is not selective, reducing plants and productivity.

title: Assessment of prenatal care for indigenous women in Brazil: findings from the First National Survey of Indigenous People’s Health and Nutrition

description: Abstract: This study assesses prenatal care for indigenous women 14-49 years of age with children under five years of age in Brazil. The First National Survey of Indigenous People’s Health and Nutrition assessed 3,967 women who met these criteria, of whom 41.3% in the North, 21.2% in the Central, 22.2% in the Northeast, and 15% in the South/Southeast. Prenatal care was offered to 3,437 (86.6%) of these women. The North of Brazil showed the highest proportion of indigenous women who did not receive prenatal care. Coverage was 90.4%, but only some 30% began prenatal care in the first trimester, and only 60% of the eligible women were vaccinated for diphtheria and tetanus. Only 16% of indigenous pregnant women had seven or more prenatal visits. Access to at least one clinical-obstetric consultation was found in 97% of the records, except for breast examination (63%). Laboratory test rates were low (blood glucose 53.6%, urinalysis 53%, complete blood count 56.9%, Pap smear 12.9%, syphilis test 57.6%, HIV serology 44.2%, hepatitis B 53.6%, rubella 21.4%, and toxoplasmosis 32.6%), as was prescription of ferrous sulfate (44.1%). As a whole, the proportion of orders for recommended laboratory tests was only 53%. The percentages of prenatal care procedures for indigenous women are lower than for non-indigenous Brazilian women as a whole, and are even lower than among women in regions with high social vulnerability and low healthcare coverage, like the Legal Amazonia and the Northeast. The results confirm the persistence of ethnic-racial inequalities that compromise the health and well-being of indigenous mothers.

title: Basic sanitation and inequalities in color/race in urban households with under-five children, with a focus on the indigenous population

description: Abstract: This study aimed to analyze the presence of basic sanitation services in households with children under five years of age located in urban areas of Brazil, with a focus on indigenous children. This cross-sectional study was based on data from the 2010 Population Census. We calculated the rates of households with running water (public system), sewage disposal (public system or septic tanks), and garbage collection (directly or via public dumpsters). Multiple logistic regression (MLR) models were used to estimate associations between color/race and presence of sanitation services, based on odds ratios (OR). The study considered Brazil’s urban metropolitan areas and stratified the results by major geographic region. Significance was set at 5%. The lowest frequencies were for sewage disposal, and all the rates were lower for indigenous people. MLR analyses included 29 comparisons (48.3%) in which households with indigenous children (compared to other color/race categories) were at a disadvantage, especially in the South of Brazil, where all comparisons were negative for indigenous households. Similar results appeared in metropolitan areas. The results thus suggest inequalities basic sanitation services based on color/race, where indigenous people are generally at a disadvantage, especially in the South of Brazil. Given the relationship between sanitation and health, as already demonstrated in the literature, these results can partly explain the low health levels in indigenous children in Brazil.

title: Ovarian Sertoli-Leydig Cell Tumors: Epidemiological, Clinical and Prognostic Factors

description: Abstract Objective To describe a series of cases of ovarian Sertoli-Leydig cell tumors (SLCTs). Methods Retrospective review of 12 cases of SLCT treated at the Hospital do Câncer de Barretos, Barretos, state of São Paulo, Brazil, between October 2009 and August 2017. Results The median age of the patients was 31 years old (15-71 years old). A total of 9 patients (75.0%) presented symptoms: 8 (66.7%) presented with abdominal pain, 5 (41.7%) presented with abdominal enlargement, 2 (16.7%) presentedwith virilizing signs, 2 (16.7%) presented with abnormal uterine bleeding, 1 (8.3%) presented with dyspareunia, and 1 (8.3%) presented with weight loss. The median preoperative lactate dehydrogenase (LDH) was 504.5 U/L (138-569 U/L), alpha-fetoprotein (AFP) was 2.0 ng/ml (1.1-11.3 ng/ml), human chorionic gonadotropin (β-hCG) was 0.6 mUI/ml (0.0-2.3 mUI/ml), carcinoembryonic antigen (CEA) was 0.9 ng/ml (0.7-3.4 ng/ml), and cancer antigen 125 (CA-125) was 26.0 U/ml (19.1-147.0 U/ml). All of the tumors were unilateral and surgically treated. Lymphadenectomy was performed in 3 (25.0%) patients, but none of the three patients submitted to lymphadenectomy presented lymph node involvement. In the anatomopathological exam, 1 (8.3%) tumor was well-differentiated, 8 (66.7%) were moderately differentiated, and 3 (25.0%) were poorly differentiated. A total of 5 (55.6%) tumors were solid-cystic, 2 (22.2%) were purely cystic, 1 (11.1%) was cystic with vegetations, and 1 (11.1%) was purely solid, but for 3 patients this information was not available. The median lesion size was 14.2 cm (3.2-23.5 cm). All of the tumors were at stage IA of the 2014 classification of the International Federation ofGynecology andObstetrics (FIGO). A total of 2 (16.7%) patients received adjuvant treatment; 1 of themunderwent 3 cycles of paclitaxel and carboplatin every 21days, and the other underwent 4 cycles of ifosfamide, cisplatin and etoposide every 21 days. None of all of the patients had recurrence, and one death related to complications after surgical staging occurred. Conclusion Abdominal pain was the most frequent presentation. There was no ultrasonographic pattern. All of the SLCTs were at stage IA, and most of them were moderately differentiated. Relapses did not occur, but one death related to the surgical staging occurred.

title: Is the Expression of the Components of the Carotid Matrix of Rats Influenced by Estrogen, Progestin and Tibolone?

description: Abstract Objective To analyze the effects of estrogen alone or in combination with progestogens and tibolone (TIB) on the expression of the extracellular matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9), of perlecan, and of heparanase (HPSE) of the vascular walls of the carotid arteries. Methods A total of 30 250-day-old ovariectomized Wistar rats were orally treated for 5 weeks with: a) 1 mg/kg of estradiol benzoate (EB); b) EB + 0.2 mg/kg of medroxyprogesterone acetate (MPA); c) EB + 0.2mg/kg of norethisterone acetate (NETA); d) EB + 2 mg/kg of dydrogesterone (DI); e) 1 mg/kg of TIB; f) placebo (CTR). Following treatment, the expression of mRNA for MMP-2, MMP-9, and HPSE was analyzed by realtime polymerase chain-reaction (PCR), and the expression of MMP-2, of MMP-9, of tissue inhibitor of metalloproteinase 2 (TIMP-2), and of perlecan was quantified by immunohistochemistry in the carotid arteries. Results The groups showed significant differences on mRNA HPSE expression (p = 0.048), which was higher in the EB, EB + MPA, and TIB groups. There was no statistically significant difference in mRNA MMP-2 or MMP-9 expression. The immunohistochemical expression of MMP-2, of TIMP-2, of MMP-9, of HPSE, and of perlecan showed no differences between groups. Conclusion Estradiol alone or associated with MPA and TIB treatment can increase mRNA HSPE expression of the walls of the carotid arteries in ovariectomized rats.

title: Exploring the Herbicidal Potential of Achyranthes aspera Against Some Weeds

description: ABSTRACT: The phytotoxic composition of Achyranthes aspera was identified through HPLC, and its herbicidal potential was investigated against two narrow leaf weeds viz., Phalaris minor Retz. and Avena fatua L.; and four broad leaf weeds viz. Lathyrus aphaca L., Vicia sativa L., Convolvolus arvensis L. and Asphodelus tenuifolius L. through bioassays. Weed seeds were grown in the aqueous extracts of various plant parts (roots, leaf, stem, fruit and whole plant) of A. aspera at 5% (w/v) concentration. The extracts of all plant parts caused significant reductions with differential degree in germination percentage and mean germination time. Phalaris minor, A. fatua, L. aphaca, V. sativa and A. tenuifolius completely failed to germinate whereas C. arvensis showed the lowest GP (20%) in response to 5% fruit extract of A. aspera. Inhibition of seed germination of all weeds was higher with the fruit extract than with the root, stem, leaf and whole plant extracts of A. aspera. Seed germination of all narrow leaf weeds was completely inhibited at the 5% fruit extract of A. aspera. The highest phytotoxic inhibitory effect of A. aspera fruit extract was proved to be due to the presence of gallic acid (88.4 mg kg-1), caffeic acid (519.2 mg g-1) and m-coumaric acid (51.4 mg kg-1) as assessed by their HPLC analyses. The study, therefore, showed that A. aspera exerts an inhibitory effect on germination of weeds and can be further explored as a pre- or post-emergence herbicide to provide natural alternative to chemical herbicides in the future.

title: Classification of color/race in children from indigenous households in Brazil

description: Abstract: Studies on racial classification systems in Brazil reveal the influence of socioeconomic factors in the expression of color/race categories, especially for whites and blacks. The aim of this study was to analyze specific family arrangements between fathers, mothers, and children, at least one of whom was indigenous. Based on the sample from the 2010 Population Census, we selected households with at least three residents (father, mother, and children), at least one of whom was indigenous. Children were characterized according to color/race (white, brown, and indigenous), sex, age, per capita household income, maternal schooling, and number of urban and rural household residents. Descriptive and multinomial logistic regression analyses were performed. We estimated a total of 290.247 children (of whom 77.1% were classified as indigenous, 13.8% brown, and 9.1% white), 74.3% living in rural households and 41.3% in the North region of Brazil; children classified as white and brown were located mostly in urban areas. The odds of children of indigenous fathers or mothers being classified as white were higher in the Southeast and South. The odds of children being classified as white or brown increased proportionally with monthly income and maternal schooling. The findings show that socioeconomic status is significantly associated with color/race classification in Brazil, including in indigenous households.

title: Pregnancy Among Women with Kidney Transplantation: A 20-Years Single-Center Registry

description: Abstract Objective To assess maternal and perinatal outcomes in pregnancies after kidney transplantation in a tertiary center in Brazil. Methods Retrospective cohort of pregnancies in women with kidney transplantation at the Universidade Estadual de Campinas, from January 1995 until December 2017. Medical charts were reviewed, andmaternal and perinatal outcomes were described as means and frequencies. Renal function and blood pressure were evaluated during pregnancy and postpartum. Results A total of 22 women had at least 1 pregnancy during the considered timeinterval, and 3 of them had &gt; 1 pregnancy, totalizing 25 pregnancies. The mean age at transplantation was of 24.6 ± 4.2 years old, and the mean time interval until pregnancy was of 67.8 ± 46.3months. Themost frequent complication during pregnancywas hypertension, which affected 11 (64.7%)women. The gestational age at delivery was 34.7 ± 4weeks, and 47% of these pregnancies were preterm (&lt; 37 weeks). A total of 88.2% of the women delivered by cesarean section. Renal function, measured by serum creatinine, remained stable during pregnancy, and the systolic blood pressure increased significantly, while the diastolic blood pressure did not differ during pregnancy. Conclusion Pregnancy after kidney transplantation is a rare event. Pre-eclampsia and prematurity were frequent complications, and cesarean section rates were very high. A specialized antenatal and postpartum care with a multiprofessional approach and continuous monitoring of graft function are essential for the early diagnosis of complications and improved outcomes.

title: Optic nerve involvement in ocular toxoplasmosis: 12 year data from a tertiary referral center in Turkey

description: ABSTRACT Purpose: To evaluate the prevalence, clinical characteristics, and types of optic nerve involvement in patients with ocular toxoplasmosis. Methods: For this retrospective cross-sectional study, we examined all patients with active ocular toxoplasmosis referred to our Uveitis Section during the last 12 years, and we included patients with optic nerve involvement in the study. The primary outcome was the prevalence of optic nerve involvement, and secondary outcomes included the types of optic nerve involvement and the final best-corrected visual acuity after treatment. Results: The prevalence of optic nerve involvement was 14.4%, with the leading cause being the activation of a juxtapapillary lesion (70.5%). We found papillitis in two eyes and neuroretinitis in two eyes (11.7% for each). We only detected one optic nerve involvement secondary to a distant active lesion (5.8%). Sixteen patients (94.1%) had unilateral ocular toxoplasmosis. The overall final best-corrected visual acuity after treatment was 10/10 (LogMAR = 0.0) excluding the three patients with a juxtapapillary scar involving the macula. Conclusions: Optic nerve involvement was common in patients with ocular toxoplasmosis. The main type of optic nerve involvement was caused by activation of an old juxtapapillary lesion. Treatment was quickly effective, but the best-corrected visual acuity was dependent on the presence of a scar in the papillomacular bundle.
