BackgroundAntiretroviral therapy (ART) in pregnancy was associated with a drastic reduction in HIV mother-to-child transmission (MTCT), although it was associated with neonatal adverse effects. The aim of this study was to evaluate the neonatal effects to maternal ART.MethodsThis study was a cohort of newborns from HIV pregnant women followed at the CAISM/UNICAMP Obstetric Clinic from 2000 to 2015. The following adverse effects were evaluated: anemia, thrombocytopenia, liver function tests abnormalities, preterm birth, low birth weight and congenital malformation. Data collected from patients’ files was added to a specific database. Descriptive analysis was shown in terms of absolute (n) and relative (%) frequencies and mean, median and standard deviation calculations. The association between variables was tested through Chi-square or Fisher exact test (n < 5) and relative risk (RR) with its respective p values for the categorical ones and t-Student (parametric data) or Mann-Whitney (non-parametric data) for the quantitative ones. The significant level used was 0.05. A multivariate Cox Logistic Regression was done. Statistical analysis was performed using SAS version 9.4.ResultsData from 787 newborns was analyzed. MTCT rate was 2.3%, with 0.8% in the last 5 years. Observed neonatal adverse effects were: liver function tests abnormalities (36%), anemia (25.7%), low birth weight (22.5%), preterm birth (21.7%), children small for gestational age (SGA) (18%), birth defects (10%) and thrombocytopenia (3.6%). In the multivariate analysis, peripartum CD4 higher than 200 cells/mm3 was protective for low birth weight and preterm birth, and C-section was associated with low birth weight, but not with preterm birth. Neonatal anemia was associated with preterm birth and exposure to maternal AZT. Liver function tests abnormalities were associated with detectable peripartum maternal viral load and exposure to nevirapine. No association was found between different ART regimens or timing of exposure with preterm birth, low birth weight or congenital malformation.ConclusionHighly active antiretroviral treatment in pregnant women and viral load control were the main factors associated with MTCT reduction. Antiretroviral use is associated with a high frequency but mainly low severity adverse effects in newborns.

Summary Objective To analyze the lifetime trajectories in genetic generalized epilepsies (GGEs) and investigate the impact of symptoms of anxiety and depression on resting state functional connectivity (FC). Methods Seventy‐four GGE patients were classified according to the pharmacological response as seizure‐free (12 patients), pharmacoresistant (PhR; 14 patients), and fluctuating (FL; 48 patients). Fifty‐four subjects completed both the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI), and 38 also underwent 3‐T resting state functional magnetic resonance imaging. These 38 patients were subdivided into a positive group (13 patients with concurrent symptoms of depression and anxiety) and a negative group (21 asymptomatic patients and four with mild anxiety or depression symptoms). For FC analysis of resting state networks, we matched 38 healthy asymptomatic volunteers and used the UF2C toolbox running on MATLAB2017/SPM12. Results The PhR group presented shorter duration of epilepsy (P = 0.016) and follow‐up (P < 0.001) compared to the FL group. The PhR group showed higher levels (median = 20) on the BAI and BDI. Myoclonic seizures were the most difficult to control, as 50% of subjects persisted with them at last appointment, compared to generalized tonic–clonic seizures and absence seizures (<40%). Patients with concurrent anxiety and depression symptoms were 7.7 times more likely to exhibit pharmacoresistant seizures, although an increase of 1 year of epilepsy duration was associated with a decrease in the odds of presenting pharmacoresistance by a factor of 0.9. Overall, FC was altered between default mode network (DMN) and visuospatial/dorsal attention. However, only the positive group displayed abnormal FC between DMN and left executive control network, and between salience and visuospatial/dorsal attention. Significance Our findings may help clinicians to have a better understanding of GGE clinical course and increase attention to the potential relationship of psychopathologies and brain connectivity.

Background Axillary lymph node involvement is one important prognostic factor in breast cancer, but the way to access this information has been modified over the years. This study evaluated if axillary ultrasound (US) coupled with fine-needle aspiration cytology (FNAC) can accurately predict clinically relevant node metastasis in patients with breast cancer, and thus assist clinical decisions Methods This is a cross-sectional study with retrospective data collection of 241 individuals (239 women and 2 men) with unilateral operable breast cancer who were submitted to preoperative axillary assessment by physical exam, US and FNAC if suspicious nodes by imaging. We calculated sensitivity, specificity, and accuracy of the methods. We compared the patient's characteristics using chi-square test, parametrics and non-parametrics statistics according to the variable. Results The most sensible method was US (0.59; 95% CI, 0.50–0.69), and the most specific was US coupled with FNAC (0.97; 95% CI, 0.92–0.99). Only 2.7% of the patients with normal axillary US had more than 2 metastatic nodes in the axillary lymph node dissection, against 50% of the patients with suspicious lymph nodes in the US and positive FNAC. Conclusions Axillary US coupled with FNAC can sort patients who have a few metastatic nodes at most from those with heavy axillary burden and could be one more tool to initially evaluate patients and define treatment strategies.

IntroductionSignificant progress of ART in HIV infection has led to a remarkable decline in mother-to-child transmission (MTCT) of HIV. However, the use of complex regimens can cause side effects to women and exposed children.The objective of this study was to evaluate side effects in pregnant women and their neonates exposed to ART at an universitary hospital in Brazil between 2000 and 2016.MethodsCohort study of 793 pregnant women and 787 newborns selected from clinical records and epidemiologic surveillance system. Analysis was performed through proportions and medians. The specific effect of different ART regimens was analysed through risk ratios (RR), qui-square test, Fisher’s exact test, student t test, Mann-Whitney test, 95% confidence interval and level of significance of 0.05.ResultsMTCT rate was 2.3%. Mean age was 28 years, more than 60% were White and diagnosed before pregnancy. HAART use: 17.4% with nevirapine (NVP), 16.9% with nelfinavir (NFV), 53.2% with lopinavir/ritonavir (LPV/R), 4.3% with other PI (26 with atazanavir/ritonavir). Only 1.9% women did not use ART by late diagnosis. There were: 56% cases of maternal anaemia,14.1% of thrombocytopenia, 54.5% of hepatic abnormalities, 2.7% of allergic reactions, 82% of dyslipidemia, 6.2% of diabetes. NVP use was associated to hepatotoxicity, allergic reactions and anaemia. NFV was associated to hepatic impairment and allergic reaction, ATV/R use was associated to bilirrubin increase, and LPV/R to dyslipidemia.Prematurity rate was 21.7% and low birth weight rate 22.5%. In the newborns: 25.7% of anaemia, 3.6% of thrombocytopenia, 36% of hepatic impairment. Congenital anomalies were presented in 10%. NVP use associated to anaemia and hepatic impairment. NFV was associated to hepatic abnormalities. ATV/R was associated to thrombocytopenia.ConclusionAlthough growing evidence indicates that antiretroviral treatment in pregnancy has overall a very favourable risk-benefit profile, it is important to maintain monitoring of the safety and efficacy of drug classes in order to optimise treatment recommendations.
