Abstract
AIM There is not much information about breast health in transgender (transexual) persons given the historical stigma that this population suffers. This research aimed to describe breast imaging patterns in transgender (trans) women and men that had been using gender affirmation hormone treatment for at least 3 years. MATERIAL AND METHODS In this observational, cross-sectional study, 67 transgender individuals (34 trans women and 33 trans men) had mammography and breast ultrasound performed. We also classified the findings by the American College of Radiology - Breast Imaging Reporting and Data System (ACR BI-RADS®). RESULTS We found that there was a higher frequency of dense breasts in trans women (75.8%) and in trans men (66,6%) than expected for cisgender (cis) women. CONCLUSIONS This study highlights the importance of a deeper understanding of the image patterns of transgender breasts because of hormonal effects that the gender transition entails so we can offer better health care and preventive services in the transgender (transexual) population.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) has been well characterised and codified through the development of diagnostic criteria. These criteria have been adapted and simplified and are widely used in clinical practice. However, there is a need to update and precisely define the criteria for both treatment response and treatment. METHODS A systematic review was performed and a modified Delphi consensus process was used to identify and redefine the response criteria in autoimmune hepatitis. RESULTS The consensus process initiated by the International Autoimmune Hepatitis Group proposes that the term 'complete biochemical response' defined as 'normalization of serum transaminases and IgG below the upper limit of normal' be adopted to include a time point at 6 months after initiation of treatment. An insufficient response by 6 months was a failure to meet the above definition. Non-response was defined as '<50% decrease of serum transaminases within 4 weeks after initiation of treatment'. Remission is defined as liver histology with a Hepatitis Activity Index <4/18. Intolerance to treatment was agreed to stand for 'any adverse event possibly related to treatment leading to potential drug discontinuation'. CONCLUSIONS These definitions provide a simple and reproducible framework to define treatment response and non-response, irrespective of the therapeutic intervention. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable inter-study comparisons. Future prospective database studies are needed to validate these endpoints. LAY SUMMARY Consensus among international experts on response criteria and endpoints in autoimmune hepatitis is lacking. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable the comparison of results between clinical trials. Therefore, the International Autoimmune Hepatitis Group (IAIHG) herein presents a statement on 5 agreed response criteria and endpoints: complete biochemical response, insufficient response, non-response, remission, and intolerance to treatment, which can be used to guide future reporting.

Abstract
Purpose Despite the evidence on the role of gravity stress test to access the instability of other ankle injuries, there is limited literature regarding gravity stress on the lateral ankle ligament’s insufficiency. The objective of our study was to objectively measure the tibiotalar angular movement under gravity stress after progressive sectioning of the lateral ankle ligaments. Methods We performed sequential sectioning of the anterior talofibular (ATFL), calcaneofibular (CFL), and posterior talofibular ligaments (PTFL) in twelve ankle specimens. Under gravity stress, we measured the angular movement of the talus in relation to the tibia. The measuring device is based on a three-axis gyroscope and accelerometer. Results Comparing to the intact condition, the plantar flexion increased on average 1.78° (95% confidence interval [CI] 1.15;2.42), 5.13° (95%CI 3.10;7.16) and 8.63° (95%CI 6.05;11.22), the rotation increased by 1.00° (95 CI -0.51;2.51), 3.68° (95%CI 1.97;5.40) and 15.62° (95%CI 10.09;21.14), and the varus increased 2.89° (95% CI 1.39, 4.39), 8.12° (95% CI 5.16, 11.07) and 11.68° (95% CI 7.91, 15.46), after sectioning the ATFL, CFL, and PTFL, respectively. The overall changes were statistically significant. Conclusions There was a significant tibiotalar laxity after sectioning of lateral ankle ligaments when the foot position is influenced only by gravity. The tibiotalar angular displacement was significant when the CFL and PTFL were cut which suggests that the gravity test could be used to assess combined lateral ankle ligament injury. This evidence might be a step forward in the development of lateral ankle ligaments gravity stress tests. Level of evidence 5 (cadaver study)

Abstract
Objective To compare the bleeding pattern in women using ethinylestradiol 20 mcg/drospirenone 3 mg (EE 20 mcg/DRSP 3 mg) in a 24/4-day cyclic regimen with an extended regimen. Unexpected bleeding/spotting in the extended regimen group was managed by allowing a 4-day hormone-free interval (HFI). Methods This was a randomized, prospective, open-label, multicenter study. Participants (N = 348) were randomized to receive EE 20 mcg/DRSP 3 mg in either an extended regimen (EE/DRSPes group) or a 24/4-day cyclic regimen (EE/DRSP24/4 group) and followed for 168 days. In the EE/DRSPes group, a 4-day HFI was allowed whenever unexpected bleeding/spotting persisted for ≥7 consecutive days. The participants assessed their bleeding daily as “no bleeding,” “spotting,” or “light,” “moderate,” or “heavy” bleeding according to a predefined scale. Results EE/DRSPes group experienced fewer days of bleeding than those using a 24/4 cyclic regimen (P < 0.001). After 168 days, 57.5% of women in the EE/DRSPes group achieved complete amenorrhea (i.e., neither bleeding nor spotting) and 73.9% achieved “no bleeding” (i.e., no bleeding with or without spotting) during the final 28-day interval of the study period. Women in the extended group who instituted the 4-day HFI experienced a 94.1% rate of successful management of unexpected bleeding/spotting. Conclusion The use of EE 20 mcg/DRSP 3 mg in an extended regimen resulted in high rates of amenorrhea and “no bleeding”. Unexpected bleeding/spotting in the EE/DRSPes group could be managed effectively with a 4-day HFI.

Abstract
BACKGROUND A 9-valent human papillomavirus (HPV6/11/16/18/31/33/45/52/58; 9vHPV) vaccine was developed to expand coverage of the previously developed quadrivalent (HPV6/11/16/18; qHPV) vaccine. METHODS Efficacy, immunogenicity, and safety outcomes were assessed in Latin American participants enrolled in 2 international studies of the 9vHPV vaccine, including a randomized, double-blinded, controlled with qHPV vaccine, efficacy, immunogenicity, and safety study in young women aged 16-26 years, and an immunogenicity and safety study in girls and boys aged 9-15 years. Participants (N=5312) received vaccination at Day 1, Month 2, and Month 6. Gynecological swabs were collected regularly in young women for cytological and HPV DNA testing. Serum was analyzed for HPV antibodies in all participants. Adverse events (AEs) were also monitored in all participants. RESULTS The 9vHPV vaccine prevented HPV 31-, 33-, 45-, 52-, and 58-related high-grade cervical, vulvar, and vaginal dysplasia with 92.3% efficacy (95% confidence interval 54.4, 99.6). Anti-HPV6, 11, 16, and 18 geometric mean titers at Month 7 were similar in the 9vHPV and qHPV vaccination groups. Anti-HPV antibody responses following vaccination were higher among girls and boys than in young women. Most (>99%) 9vHPV vaccine recipients seroconverted for all 9 HPV types at Month 7. Antibody responses to the 9 HPV types persisted over 5 years. The most common AEs were injection-site related, mostly of mild to moderate intensity. CONCLUSIONS The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Latin American young women, girls, and boys. These data support 9vHPV vaccination programs in Latin America, a region with substantial cervical cancer burden.

Abstract
The combined liver-kidney transplantation (cLKT) is the procedure of choice for patients with end-stage liver and kidney disease. In cLKT we can usually accommodate the grafts in two different ways, varying the kidney placement. The retroperitoneal kidney implant has some advantages, such as the easy access or avoiding vascular complications. We propose a new single incision, not yet reported, maintaining an extraperitoneal kidney, with excellent surgical field for cLKT and possible reduction of the impact of wound complications.

Abstract
The scientific literature has shown positive results regarding intra-articular injections of hyaluronic acid in osteoarthritic joints. When injecting in the hip joint, the guidance of ultrasound can provide higher injection accuracy and repeatability. However, due to the methodological limitations in the current available literature, its recommendation in the current practice is still controversial. This study shows that ultrasound-guided intra-articular injections of triamcinolone hexacetonide and hyaluronic acid can improve pain, function and quality of life in patients with symptomatic and radiographic hip osteoarthritis. In addition, the administration of triamcinolone hexacetonide and hyaluronic acid to the hip joint in these patients can delay the need for interventional surgery.

Abstract
Our understanding of G protein-coupled receptors (GPCRs) in the central nervous system (CNS) has been hampered by the limited availability of tools allowing for the study of their signaling with precise temporal control. To overcome this, we tested the utility of the bistable mammalian opsin melanopsin to examine G protein signaling in CNS neurons. Specifically, we used biolistic (gene gun) approaches to transfect melanopsin into cortical pyramidal cells maintained in organotypic slice culture. Whole cell recordings from transfected neurons indicated that application of blue light effectively activated the transfected melanopsin to elicit the canonical biphasic modulation of membrane excitability previously associated with the activation of GPCRs coupling to Gαq-11 Remarkably, full mimicry of exogenous agonist concentration could be obtained with pulses as short as a few milliseconds, suggesting that their triggering required a single melanopsin activation-deactivation cycle. The resulting temporal control over melanopsin activation allowed us to compare the activation kinetics of different components of the electrophysiological response. We also replaced the intracellular loops of melanopsin with those of the 5-HT2A receptor to create a light-activated GPCR capable of interacting with the 5-HT2A receptor interacting proteins. The resulting chimera expressed weak activity but validated the potential usefulness of melanopsin as a tool for the study of G protein signaling in CNS neurons.

Abstract
Today cancer research studies have highlighted the role of the cancer-stroma interaction in the regulation of invasive processes. However, very little is known about cell-to-cell relationships between germinal cancer cells and the somatic ones belong to their close environment, particularly at early invasion stages. Here, we have studied the potential role of the seminiferous peritubular myoid cells (PTCs), as potential part of the reactive stroma, like tumor myofibroblast, in the progression of embryonal carcinoma (EC). To this end, we show results on the in vitro interactions between F9 murine embryonal carcinoma cells (EC cells) and primary cultures of murine PTCs, using contact-dependent and contact-independent 2D co-cultures. In these circumstances, when EC cells interact with PTCs they change their migratory behavior and matrix-metalloproteinase 9 (MMP-9) was up-regulated in PTCs. Additionally, among a variety of cytokines implicated in tumor-stroma cross-talk, we have examined in more detail the influence of tumor necrosis factor alpha (TNF-α). In this regard, it was observed that this cytokine induced a MMP-9 secretion by PTCs in a pattern dependent on its concentration, whereas does not increase the migration capacity of cancer cells. All together, our results provide evidence for a role played by peritubular myoid cells and cancer-cell secreted TNF- α for a change in the tumor microenvironment during the early stages of EC progression.

Abstract
This study examined whether a high-intensity, moderate-duration bout of stretching would produce the same acute effects as a low-intensity, long-duration bout of stretching. 17 volunteers performed 2 knee-flexor stretching protocols: a high-intensity stretch (i. e., 100% of maximum tolerable passive torque) with a moderate duration (243.5 ± 69.5-s); and a low-intensity stretch (50% of tolerable passive torque) with a long duration (900-s). Passive torque at a given sub-maximal angle, peak passive torque, maximal range of motion (ROM), and muscle activity were assessed before and after each stretching protocol (at intervals of 1, 30 and 60 min). The maximal ROM and tolerable passive torque increased for all time points following the high-intensity stretching (p<0.05), but not after the low-intensity protocol (p>0.05). 1 min post-stretching, the passive torque decreased in both protocols, but to a greater extent in the low-intensity protocol. 30 min post-test, torque returned to baseline for the low-intensity protocol and had increased above the baseline for the high-intensity stretches. The following can be concluded: 1) High-intensity stretching increases the maximal ROM and peak passive torque compared to low-intensity stretching; 2) low-intensity, long-duration stretching is the best way to acutely decrease passive torque; and 3) high-intensity, moderate-duration stretching increases passive torque above the baseline 30 min after stretching.

Abstract
Abstract
Co-extruded films with up to 65 layers of two rheologically mismatched polymer systems – polystyrene/poly(methylmethacrylate) (PS/PMMA) and hard/soft thermoplastic polyurethanes (TPUs) – were successfully produced using a combination of a 9-layer feedblock, low-pressure drop multiplier dies, and external lubricants. Formation of viscoelastic instabilities was studied using a custom visualization and by finite element method (FEM) simulations of a standard multiplier. The results showed that the flow inside the standard multiplier die is highly non-uniform, with severe gradients in shear and normal stresses and viscous encapsulation occurring mainly in the initial multiplication stages where there is enough material available in the low-viscosity layers to proceed with the encapsulation. To mitigate layer degradation the standard 2- or 3-layer feedblock was replaced with a 9-layer one, thereby decreasing the thickness of each layer at the end of the feedblock. Also, subsequent layering was performed using a low flow resistance die. This new multiplier die yields a more uniform flow profile and imparts a more homogeneous thermo-mechanical history on the melt which results in an improved layer stability. Simulations showed that in the standard die the second normal-stress difference (N2) responsible for elastic instabilities at the edges of the die are very high. These can be reduced by inducing slip at the wall resulting in be much improved layer uniformity and stability. This was accomplished experimentally via the use of external lubricants, and the resulting layered structure was indeed much better than was possible to achieve with the conventional multiplier dies.

Abstract
Microbial growth on medical and technical devices is a big health issue, particularly when microorganisms aggregate to form biofilms. Moreover, the occurrence of antibiotic-resistant bacteria in the clinical environment is dramatically growing, making treatment of bacterial infections very challenging. In search of an alternative, we studied a novel antimicrobial surface coating based on micro galvanic elements formed by silver and ruthenium with surface catalytic properties. The antimicrobial coating efficiently inhibited the growth of the nosocomial pathogens Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Enterococcus faecium as demonstrated by the growth inhibition on agar surface and in biofilms of antibiotic resistant clinical E. faecalis, E. faecium, and S. aureus isolates. It also strongly reduced the growth of Legionella in a drinking water pipeline and of Escherichia coli in urine. We postulate a mode of action of the antimicrobial material, which is independent of the release of silver ions. Thus, the novel antimicrobial coating could represent an alternative to combat microbial growth avoiding the toxic side effects of high levels of silver ions on eukaryotic cells.

Abstract
Mind-body interventions, such as yoga, that teach stress management with physical activity may be well suited for investigation in both osteoarthritis and rheumatoid arthritis. In order to be considered as viable care options integrative studies need to offer a comprehensive design and include clinicians familiar with the disease process of the study populations. A review of the literature reveals a dearth of information related to the collaboration between yoga and physical rehabilitation medicine. This article discusses the collaboration with physical rehabilitation medicine to collect relevant pre- and post-intervention measures for an on-going pilot acceptability/feasibility yoga study for minority patients with osteoarthritis or rheumatoid arthritis. An interdisciplinary clinical research team selected psychosocial and physical measures for a community sample of bilingual minority patients, not typically identified as practicing yoga. Sixteen female adults aged 40–63 years (mean =51) completed baseline physical assessments using single leg stance, functional reach test, time up and go test, timed up from the floor test and the Disabilities of the Arm, Shoulder and Hand measures. Baseline values show an average level of functional ability prior to beginning the intervention. Preliminary results indicate some improvement; however, selected measures may not have the sensitivity and specificity needed to identify significant change. In this study, combining interdisciplinary perspectives enhanced the quality of the research study design. The experience of this interdisciplinary clinical research team opens the discussion for future collaborations.

Abstract
Purpose: To assess the effect of hepatitis A virus (HAV) infection on HIV viral load (VL) and the influence of HIV on the clinical expression of HAV infection. Methods: Single-center study of 23 HIV-positive patients and 41 HIV-negative patients diagnosed with acute HAV infection during 2008-2009. The impact of HAV on HIV VL was defined as an increase of >0.5 log10 during the event, or a detectable VL for those previously suppressed patients. Results: The impact of acute HAV on VL was observed in 37.5% patients. HIV-negative patients were younger (27 vs 34 years, P < .0001), and serum transaminases levels normalized earlier than in the HIV-positive patients (121 vs 178 days, P < .05). Conclusions: Acute HAV infection may have an impact on HIV VL. The interactions between the 2 viruses may not only prolong the HAV viremia, with a potential increase in the transmission of infection, but the impact on HIV may increase the risk of HIV transmission. Studies with higher sample size are needed to confirm our results.

Abstract
INTRODUCTION The purpose of this study was to compare the electromyography index of muscle coactivation of the following muscle pairs: posterior deltoid and pectoralis major (PD/PM); triceps brachii and biceps brachii (TB/BB); and serratus anterior and upper trapezius (SA/UT) during three different closed kinetic chain exercises (wall-press, bench-press and push-up) on an unstable surface at the maximal load. METHODS A total of 20 healthy sedentary men participated in the study. Integral linear values were obtained from three sustained contractions of six seconds each for the three proposed exercises. Mean coactivation index values were compared using the mixed-effects linear model, with a five percent significance level. RESULTS Electromyography indexes of muscle coactivation showed significant differences for the PD/PM and TB/BB muscle pairs. No differences were found between exercises for the SA/UT muscle pair. CONCLUSION Our results seem to differ from those of previous studies, which reported that the similarity in exercises performed is responsible for the comparable muscle activation levels.

Abstract
INTRODUCTION The complicated forms of rolandic epilepsy progress with a continuous spike-wave pattern in slow-wave sleep. Experiments conducted in cats suggest that this pattern can only appear if there is bilateral thalamic insult. AIM. To determine whether thalamic hypoperfusion is associated with the complicated variants of rolandic epilepsy. PATIENTS AND METHODS A group of 24 children were studied over a period of six years following their first epileptic seizure. During the follow-up an interictal magnetic resonance scan and single-photon emission computerised tomography (SPECT) were performed. Results were examined to ascertain whether there were asymmetries in the distribution of cerebral blood flow through structures, using parametric statistical maps. The brain SPECT was performed when progression to atypical benign partial epilepsy in infancy was diagnosed and in typical forms of rolandic epilepsy when there was some mild neuropsychological deficit that led the specialist to suspect the existence of a focal cortical lesion. RESULTS Bilateral thalamic hypoperfusion was found in all patients diagnosed with atypical benign partial epilepsy in infancy, which was correlated with the presence of continuous spike-waves during the slow-wave phase of non-REM sleep. CONCLUSIONS Bilateral thalamic hypoperfusion seems to be a necessary condition for the atypical progression of rolandic epilepsy.

Abstract
The effects of fluctuating initial conditions are studied in the context of relativistic heavy ion collisions where a rapidly evolving system is formed. Two-particle correlation analysis is applied to events generated with the NEXSPHERIO hydrodynamic code, starting with fluctuating nonsmooth initial conditions (IC). The results show that the nonsmoothness in the IC survives the hydroevolution and can be seen as topological features of the angular correlation function of the particles emerging from the evolving system. A long range correlation is observed in the longitudinal direction and in the azimuthal direction a double peak structure is observed in the opposite direction to the trigger particle. This analysis provides clear evidence that these are signatures of the combined effect of tubular structures present in the IC and the proceeding collective dynamics of the hot and dense medium.

Abstract
INTRODUCTION To date no controlled, randomised studies with flexible dose regimens have been conducted in children with rolandic epilepsy, and therapy is therefore still empirical. AIM To evaluate the effectiveness and safety of clobazam (CLB) compared with that of carbamazepine (CBZ) in rolandic epilepsy. PATIENTS AND METHODS A prospective, open, controlled and randomised study was carried out to compare CBZ and CLB in children with rolandic epilepsy with a follow-up over a two-year period. A random sample of 45 patients was taken and 38 of them finished the study. A flexible dose regimen was indicated. Control of seizures, academic performance, behaviour, adherence to treatment, parents' degree of satisfaction and side effect profiles were all evaluated. RESULTS Both drugs were equally effective at controlling seizures (94.1% of patients with CLB and 100% of those with CBZ were free of seizures on ending the study; p = 0.26). CLB controlled seizures earlier (33.3 +/- 45 days versus 48.2 +/- 72.3; p < 0.05) and had fewer side effects than CBZ (side effects appeared in three patients with CLB and in eight of those on CBZ; p = 0). In two of the patients taking CBZ, the seizures got worse and a series of cognitive-behavioural complications also appeared. CONCLUSIONS CBZ is an effective drug in rolandic epilepsy, but it may be associated with exacerbation of seizures as well as with cognitive-behavioural impairment. CLB in monotherapy seems to be an effective and better tolerated drug in this kind of epilepsy.

Abstract
Adequate initial configurations for molecular dynamics simulations consist of arrangements of molecules distributed in space in such a way to approximately represent the system's overall structure. In order that the simulations are not disrupted by large van der Waals repulsive interactions, atoms from different molecules must keep safe pairwise distances. Obtaining such a molecular arrangement can be considered a packing problem: Each type molecule must satisfy spatial constraints related to the geometry of the system, and the distance between atoms of different molecules must be greater than some specified tolerance. We have developed a code able to pack millions of atoms, grouped in arbitrarily complex molecules, inside a variety of three-dimensional regions. The regions may be intersections of spheres, ellipses, cylinders, planes, or boxes. The user must provide only the structure of one molecule of each type and the geometrical constraints that each type of molecule must satisfy. Building complex mixtures, interfaces, solvating biomolecules in water, other solvents, or mixtures of solvents, is straightforward. In addition, different atoms belonging to the same molecule may also be restricted to different spatial regions, in such a way that more ordered molecular arrangements can be built, as micelles, lipid double-layers, etc. The packing time for state-of-the-art molecular dynamics systems varies from a few seconds to a few minutes in a personal computer. The input files are simple and currently compatible with PDB, Tinker, Molden, or Moldy coordinate files. The package is distributed as free software and can be downloaded from http://www.ime.unicamp.br/~martinez/packmol/.

Abstract
BACKGROUND Carcinoma in situ (CIS) of the testis is considered to be a precancerous germinal cell lesion, but the precise cellular and molecular mechanisms underlying transformation of CIS into invasive pluripotent cancer cells remain to be elucidated. Moreover, a satisfactory animal model for the experimental study of germinal tumours has not been developed to date. METHODS We have developed a tumour model that involves the microinjection of green fluorescent protein-labelled embryonic stem (ES) cells (which are functionally equivalent to CIS cells) into syngenic mouse seminiferous tubules, a unique cell microenvironment in which germinal cells mature and CIS arise. To characterise the vascularisation of teratocarcinomas, which arise after cell transplant, we used immunohistochemistry, together with a qualitative and quantitative analysis of scanning electron microscopy images of corrosion casting samples. RESULTS Embryonic stem cells transplanted into seminiferous tubules did not differentiate into germinal cells, but rather they behaved as invasive embryonal carcinoma (EC) stem cells. The vascular pattern of the experimental teratocarcinomas showed a highly disorganised architecture, and some of the neoplastic capillaries were derived, at least in part, from the original transplanted ES cells. CONCLUSION The transplantation of pluripotent ES cells into seminiferous tubules efficiently recapitulates the early stages of development of teratocarcinomas. Consequently, this method constitutes a novel in vivo model to study the mechanisms of invasion and progression of experimental germinal tumours.

Abstract
OBJECTIVE To study the factors associated with an adverse pregnancy outcome in women with systemic lupus erythematosus (SLE). METHODS SLE women from LUMINA of Hispanic, African American and Caucasian ethnicity were studied. Adverse pregnancy outcome was a miscarriage or abortion (<20 weeks), a stillbirth (> or = 20) and/or a moderate to severe preterm-baby (<34 weeks); good outcome was either a mild preterm-baby (> or = 34 weeks) or a full-term baby [C-section or vaginal delivery (38-42 weeks)]. Pregnancies occurring after SLE diagnosis (TD) were included; pregnancy outcome was the unit of analyses. The relationship between selected variables and pregnancy outcomes was examined by univariable and multivariable analyses. RESULTS Adverse outcomes occurred in 63.7% of 102 pregnancies. In the univariable analyses, Texan Hispanic and African American ethnicities, fewer years of education, higher number of ACR criteria, renal involvement, glucocorticoid exposure and the maximum dose of glucocorticoids used prior to the pregnancy outcome were associated with an adverse pregnancy outcome. Renal involvement was independently associated with an adverse pregnancy outcome [Odds ratio (OR)=5.219 (95% Confidence Interval (CI) 1.416-19.239, p=0.0131] as were the maximum dose of glucocorticoids used prior to the pregnancy outcome (OR=1.028; CI:1.002-1.054; p=0.0315) and fewer years of education (OR=1.204; CI:1.006-1.472; p=0.0437). Ethnicity was not retained in the multivariable model. CONCLUSION Renal involvement, the maximum dose of glucocorticoids used prior to pregnancy and fewer years of education were associated with adverse pregnancy outcomes. These data have implications for the management of women with lupus planning to become pregnant.

Abstract
BACKGROUND Although thousands of infants under the age of 12 months die each year from pneumonia in Latin America, little is known regarding the true occurrence of pneumonia, wheezing and other related respiratory illnesses in this age group. METHODS AND RESULTS In order to describe the prevalence and risk factors for radiologically confirmed pneumonia during the first year of life, a birth-cohort (n = 188) of infants born in a low-income area in Santiago, Chile was followed up monthly. RESULTS The prevalence of pneumonia during the first year of life was 13.3 % and there were no fatal events. Exclusive breastfeeding during the first 4 months of life was more prevalent in the non pneumonia group; conversely, wheezing episodes during 0-3 and 3-6 months of age, and hospitalization due to lower respiratory infection during 3-6 and 9-12 months of age were more prevalent in the pneumonia group. After a logistic multivariate analysis, the only risk factor that remained related with pneumonia was wheezing during the first 3 months of life (adjusted OR: 7.7, 95 CI: 1.32-44.92, p = 0.024); while breastfeeding during the first 4 months was an independent protective factor for pneumonia (adjusted OR: 0.11, 95 CI: 0.03-0.44, p = 0.002). CONCLUSION The significant protective effect of exclusive breast feeding against pneumonia in this cohort and the evident role of recurrent wheezing as risk factor for pneumonia during the first year of life support the implementation or reinforcement of public policies encouraging exclusive breastfeeding and an adequate management of wheezing since the first months of life.

Abstract
INTRODUCTION Benign focal epilepsy in infancy with centro-temporal paroxysms is a frequent form of epilepsy within this group of epilepsies. Despite its relative benignity, however, it may be accompanied by neuropsychological deficits and therefore constitutes a suitable in vivo model for studying how the brain functions when processing information. CASE REPORT We report the case of a 7-year-old child who began with this type of epilepsy by manifesting focal seizures during the early stages of sleep and who, with the absence of any continuous spike-wave activity in non-REM sleep, presented transient unilateral neglect syndrome on the right-hand side related with electroencephalographic intercritical activity. CONCLUSIONS The neuropsychological manifestations in this type of epilepsy can be due to intercritical paroxysmal activity. The clinical features depend on where the paroxysms are located and in which direction they spread. A dysfunction of the physiological neuronal synchrony among the neuronal networks that are necessary for thinking processes could be the cause of this disorder.

Abstract
The benefit of the triple therapy (interferon + amantadine + ribavirim) is still unknown. The efficacy of induction doses of interferon-alpha-2a monotherapy or in combination with ribavirin and/or amantadine was evaluated in interferon non-responders with chronic hepatitis C. A total of 378 patients were randomized. All the groups received the same doses and duration of interferon-alpha-2a: (i) interferon 9 MUI/day for 4 weeks and then 3 MUI/3 t.i.w. for 44 weeks (n = 53); (ii) interferon in combination with amantadine 100 mg twice daily for 48 weeks (n = 111); (iii) interferon in combination with ribavirin 1000-1200 mg (n = 106); (iv) interferon in combination with amantadine and ribavirin (n = 108). Baseline parameters were similar in the four groups. Sustained virological and biochemical responses were 13%, 6%, 18% and 22% respectively. No significant differences were found between double ribavirin arm vs triple therapy, but the difference was significant between interferon-amantadine (P = 0.008) and triple therapy (P = 0.0005). Hence, the induction doses of interferon in combination with ribavirin or ribavirin plus amantadine showed encouraging results in patients with chronic hepatitis C who were resistant to interferon. However, triple therapy is not superior to double.

Abstract
Elliptic flow at BNL RHIC is computed event by event with NeXSPheRIO. We show that when symmetry of the particle distribution in relation to the reaction plane is assumed, as usually done in the experimental extraction of elliptic flow, there is a disagreement between the true and reconstructed elliptic flows (15%-30% for eta=0, 30% for p perpendicular=0.5 GeV). We suggest a possible way to take into account the asymmetry and get good agreement between these elliptic flows.

Abstract
Retinoic acid-induced apoptosis of embryonic stem (ES) cells is an experimental system which resembles the physiological programmed cell death that occurs during differentiation in embryonic development. Our aim was to analyze the involvement of epigenetic modifications such as DNA methylation and chromatin structure in the apoptotic process and to investigate the metabolic activity of apoptotic bodies. We found a relationship between DNA methylation and apoptosis, shown by a dose-dependent induction of apoptosis after treatment with the inhibitor of DNA methylation 5-aza-2'-deoxycytidine. Interestingly, we found a slight demethylation of specific sequences of the U2afl-rs1 imprinted gene in those RA treated cells which were specifically undergoing apoptosis. In addition, apoptotic bodies exhibited an unexpected open chromatin conformation accessible to the endonuclease DNase-I. Furthermore, we observed a structural and functional preservation of specific DNA sequences and mRNA. These results suggest that biological activities, such as transcription or protein synthesis, could be maintained even towards the end of the apoptotic process.
