Abstract
BACKGROUND Malaria is a deadly disease caused by Plasmodium spp. Several blood phenotypes have been associated with malarial resistance, which suggests a genetic component to immune protection. METHODS One hundred and eighty-seven single nucleotide polymorphisms (SNPs) in 37 candidate genes were genotyped and investigated for associations with clinical malaria in a longitudinal cohort of 349 infants from Manhiça, Mozambique, in a randomized controlled clinical trial (RCT) (AgeMal, NCT00231452). Malaria candidate genes were selected according to involvement in known malarial haemoglobinopathies, immune, and pathogenesis pathways. RESULTS Statistically significant evidence was found for the association of TLR4 and related genes with the incidence of clinical malaria (p = 0.0005). These additional genes include ABO, CAT, CD14, CD36, CR1, G6PD, GCLM, HP, IFNG, IFNGR1, IL13, IL1A, IL1B, IL4R, IL4, IL6, IL13, MBL, MNSOD, and TLR2. Of specific interest, the previously identified TLR4 SNP rs4986790 and the novel finding of TRL4 SNP rs5030719 were associated with primary cases of clinical malaria. CONCLUSIONS These findings highlight a potential central role of TLR4 in clinical malarial pathogenesis. This supports the current literature and suggests that further research into the role of TLR4, as well as associated genes, in clinical malaria may provide insight into treatment and drug development.

Abstract
Abstract
Introduction
The infection caused by the Zika virus during pregnancy causes microcephaly and brain damage in fetus, and the systemic involvement with diffuse muscle impairment, high frequency of arthrogryposis and microphthalmia, characterizes congenital Zika syndrome (CZS). The cardiac impairment in CZS was rarely evaluated.
Purpose
To evaluate the morphology and biventricular cardiac function in children affected by CZS, using electrocardiogram (EKG), echocardiogram and biomarkers dosage.
Methods
This is a cross-sectional study conducted with 52 children with CZS (GZ) compared with 25 healthy children (CG). Clinical evaluation, EKG, and echocardiogram were performed in all of them. Also, troponin I and natriuretic peptide type B (BNP) dosages were performed in GZ.
Results
The median age of the studied population was 5 years in groups, GZ (3 to 6 years), CG (3 to 8 years), 40.4% (GZ) and 60% (CG) of female gender. The most prevalent electrocardiographic alteration was sinus arrhythmia, GZ: 9 (17.3%) and CG: 4 (16%). The echocardiographic evaluation showed the morphological parameters adjusted for the Z score: left ventricular (LV) end-diastolic diameter in GZ: −2.36 [−5.10, 2.63] vs CG: −1.07 [−3.43, 0.61], p<0.001; LV end-systolic diameter in GZ: −1.02 [−4.49, 0.62] vs CG: −0.06 [−1.98, 2.28], p<0.01; ascending aorta in GZ: −0.09 [−2.08, 1.60] vs CG: 0.43 [−1.47, 2.2], p: 0.021; basal diameter of the right ventricle (RV) in GZ: −2.34 [−4.90, 0.97] vs CG: −0.96 [−2.21, 0.40], p<0.01; pulmonary artery dimension in GZ: −2.13 [−5.99, 0.98] vs CG: −0.24 [−2.53, 0.59], p<0.01. The left atrium volume index (ml/m2) was in GZ: 13.15 [6.80, 18.00] vs CG: 18.80 [5.90, 25.30], p<0.01; right atrium volume index (ml/m2) in GZ: 10.10 [4.90, 15.30] vs CG: 15.80 [4.10, 24.80], p<0.01. The septum systolic excursion of the mitral annular plane (MAPSE, cm) was in GZ: 0.98 [0.78, 1.66] vs CG: 1.25 [1.07, 1.56], p<0.01; and lateral annulus: 1.25 [0.81, 1.86] vs CG: 1.46 [1.07, 1.83], p<0.001; tricuspid annular plane systolic excursion (cm) in GZ: 1.52 [1.13, 2.34] vs CG: 1.90 [1.62, 2.35], p<0.01; S' of the RV (cm/s) was in GZ: 10.60 [6.49, 21.00] vs CG: 12.80 [9.19, 16.20], p<0.01. The peak of late mitral inflow (A wave, cm/s) was in GZ: 64 [24, 134] vs CG: 52 [26, 94], p=0.02; peak of late diastolic mitral annular wave (e') of septum (cm/s) was GZ: 15 [7, 23] vs CG: 17 [12, 27], p<0.01; peak of e' lateral (cm/s) was in GZ: 11 [7, 19], CG: 12 [9, 15], p<0,016; E/e' ratio was GZ: 7.52 [4.57, 10.78] vs CG: 6.41 [4.75, 12.64], p<0.01. The LV longitudinal and circumferential and RV longitudinal strain measurements showed no difference between the groups.
Conclusion
A reduction in cardiac dimensions and biventricular dysfunction was found in CZS, showing an early cardiac impairment, which will enable to establishment early therapies, avoiding severe heart failure.

Abstract
Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong influence on mitochondrial genomes, to the point of promoting the persistence of certain genotypes in order to compensate for the metabolic requirements of the local environment. As recently discovered, the gentoo penguins (Pygoscelis papua) comprise four highly divergent lineages across their distribution spanning the Antarctic and sub-Antarctic regions. Gentoo penguins therefore represent a suitable animal model to study adaptive processes across divergent environments. Based on 62 mitogenomes that we obtained from nine locations spanning all four gentoo penguin lineages, we demonstrated lineage-specific nucleotide substitutions for various genes, but only lineage-specific amino acid replacements for the ND1 and ND5 protein-coding genes. Purifying selection (dN/dS < 1) is the main driving force in the protein-coding genes that shape the diversity of mitogenomes in gentoo penguins. Positive selection (dN/dS > 1) was mostly present in codons of the Complex I (NADH genes), supported by two different codon-based methods at the ND1 and ND4 in the most divergent lineages, the eastern gentoo penguin from Crozet and Marion Islands and the southern gentoo penguin from Antarctica respectively. Additionally, ND5 and ATP6 were under selection in the branches of the phylogeny involving all gentoo penguins except the eastern lineage. Our study suggests that local adaptation of gentoo penguins has emerged as a response to environmental variability promoting the fixation of mitochondrial haplotypes in a non-random manner. Mitogenome adaptation is thus likely to have been associated with gentoo penguin diversification across the Southern Ocean and to have promoted their survival in extreme environments such as Antarctica. Such selective processes on the mitochondrial genome may also be responsible for the discordance detected between nuclear- and mitochondrial-based phylogenies of gentoo penguin lineages.

Abstract
Abstract
Introduction
Severe aortic stenosis (AS) and mitral regurgitation (MR) often coexist. Transcatheter aortic valve implantation (TAVI) is becoming widely used for the treatment of patients (pts) with symptomatic severe AS. However, conflicting data reside concerning the impact of MR on outcomes after TAVI. Also, very few data exist regarding the benefits of a cardiac rehabilitation program (CRP) following TAVI in pts with MR.
Purpose
To evaluate the effect of a CRP in functional parameters after TAVI, particularly in pts with MR grade ≥ II.
Methods
Retrospective study which included all pts submitted to TAVI between 2014 and 2020 that completed a CRP following the procedure. Cardiopulmonary exercise tests (CPET) were performed after TAVI at baseline (pre-CRP) and post-CRP. We evaluated pre- and post-CRP peak oxygen consumption (pVO2), pVO2 at the anaerobic threshold (AT), respiratory exchange ratio (RER), VE/VCO2 and CPET duration. The exercise protocol included low/medium intensity exercises and consisted of sessions 3 times per week carried over 3 months. MR grading severity was assessed with transthoracic echocardiography performed after TAVI and was divided into 2 groups (grade < II vs grade ≥ II).
Results
Fifty-two pts were included, 59,6% were male, mean age of 78,6±8,6 years-old. Mean Society of Thoracic Surgery (STS) risk score was 4,9. Mean pre-TAVI aortic valve area was 0,68 cm2, with a mean gradient of 45,5 mmHg and a mean ejection fraction (EF) of 51%. The majority of pts implanted a self-expandable prosthesis (55,8%).
Twenty-seven (51,9%) pts had MR grade ≥ II. Baseline characteristics were similar between pts with MR grade < II vs MR grade ≥ II, with the exception of the prevalence of coronary artery disease which was higher in MR grade ≥ II (p=0,036). Patients with MR grade < II had higher maximum and median aortic gradients before TAVI (p<0,05 for all). The mean number of cardiac rehabilitation sessions was 21±7, without differences between both groups. In pts with MR grade ≥ II, there was an improvement in CPET duration after CRP (HF protocol from 03:57 min to 05:02 min; p=0,017 and modified Bruce protocol from 06:03 min to 06:41 min; p=0,049) but without significant changes in pVO2 (14,7 mL/kg/min to 14,9 mL/kg/min; p=0,990), RER or VEVCO2/VO2 ratio. Patients with MR grade < II significantly improved pVO2 (13,8 mL/kg/min to 14,7 mL/kg/min; p=0,015), and CPET duration with HF protocol from 05:04 min to 06:23 min; p=0,006 after CRP. There was also an improvement in VEVCO2/VO2 ratio, although not statically significant.
Conclusions
Patients with MR grade < II after TAVI who underwent a CRP significantly improved pVO2 and CPET duration. Although pts with MR grade ≥ II did not improved pVO2 after a CRP, an improvement in CPET duration may translate into a clinical benefit in these pts. These results highlight the importance of further research and personalization among this potentially higher risk subset of pts.

Abstract
BACKGROUND The effect of timing of exposure to first Plasmodium falciparum infections during early childhood on the induction of innate and adaptive cytokine responses and their contribution to the development of clinical malaria immunity is not well established. METHODS As part of a double-blind, randomized, placebo-controlled trial in Mozambique using monthly chemoprophylaxis with sulfadoxine-pyrimethamine plus artesunate to selectively control timing of malaria exposure during infancy, peripheral blood mononuclear cells collected from participants at age 2.5, 5.5, 10.5, 15, and 24 months were stimulated ex vivo with parasite schizont and erythrocyte lysates. Cytokine messenger RNA expressed in cell pellets and proteins secreted in supernatants were quantified by reverse-transcription quantitative polymerase chain reaction and multiplex flow cytometry, respectively. Children were followed up for clinical malaria from birth until 4 years of age. RESULTS Higher proinflammatory (interleukin [IL] 1, IL-6, tumor necrosis factor) and regulatory (IL-10) cytokine concentrations during the second year of life were associated with reduced incidence of clinical malaria up to 4 years of age, adjusting by chemoprophylaxis and prior malaria exposure. Significantly lower concentrations of antigen-specific T-helper 1 (IL-2, IL-12, interferon-γ) and T-helper 2 (IL-4, IL-5) cytokines by 2 years of age were measured in children undergoing chemoprophylaxis compared to children receiving placebo (P < .03). CONCLUSIONS Selective chemoprophylaxis altering early natural exposure to malaria blood stage antigens during infancy had a significant effect on T-helper lymphocyte cytokine production >1 year later. Importantly, a balanced proinflammatory and anti-inflammatory cytokine signature, probably by innate cells, around age 2 years was associated with protective clinical immunity during childhood.

Abstract
Abstract
Introduction Benefits arising from blueberry (BB) consumption are well-described in type 2 diabetes evolution and inherent complications. Lending further support to this thesis, previous work from our group unequivocally demonstrates BB supplementation efficacy to manage prediabetic hepatic liver steatosis. Whether a similar effect also holds truth in early renal impairment is an unsolved issue.
Objectives To address blueberry juice (BJ) ability to exert renoprotective effects in experimental prediabetes.
Methodology Diet-induced prediabetes [high-sucrose (35% Hsu) and high-fat (60% HF)] was developed in adult male Wistar rats through the ingestion of HSu for 9 weeks supplemented by HF for another 14 weeks (HSuHF, n = 16). On W9, half of the former animals orally received BJ (25g/kg BW, HSuHF+BJ). Control animals (n = 8) received standard diet during the entire protocol. Functional [serum and urinary creatinine, uric acid, glucose; glomerular filtration rate (GFR)], structural [H&E and Oil Red O staining] and molecular [triglycerides content and inflammation (RT-qPCR, WB)] markers of renal injury were assessed along with metabolic profile.
Results Even though diet-induced glucose intolerance, insulin insensitivity and plasmatic hypertriglyceridemia were significantly ameliorated upon BJ treatment, this nutraceutical intervention was unable to halt or slow down renal lipidosis and glomerular crescent-like lesions apart from a slight amelioration of both GFR and IL-6 levels in HSuHF-treated rats.
Conclusion Unlike previous results clearly demonstrating the ability of BJ nutraceutical intervention to afford protection against metabolic impairment and hepatic steatosis evolution in experimentally diet-induced prediabetes, only a modest renoprotective effect was observed in functional and morphological renal endpoints. Future studies are warranted to dissect the divergent effects of BJ on early liver and kidney impairment.

Abstract
The aim of the present work was to investigate if flowers extract (FE) and leaf extract (LE) of Baccharis ilimita (Asteraceae) induced antidepressant-like effect. Previous phytochemical investigations have shown the presence of structurally and biogenetically diverse secondary metabolites in this gene, such as flavonoids, diterpenes and triterpenes. Male Swiss mice were injected with FE and LE (12.5; 25.0 or 50.0 mg/kg; i.p.) or saline (S) and after 30 min, they were tested in the forced swimming test (FST). The results showed that FE and LE (50 mg/kg) decreased the duration of immobility time in comparison to the control group (S: 114.8s ± 10.23; FE50: 47.52s ± 9.45; LE50: 53.36s ± 10.38). However, the 12.5 and 25.0 mg/kg doses had no effect on the immobility time in comparison to the control group. The FE and LE did not produce any change in ambulation in mice when tested in an open field. The imipramine (IMP; 15.0 mg/kg i.p.) was used as the positive control. Our results suggested that FE and LE of Baccharis ilimita presents antidepressant-like effect in mice. Such results suggest that the antidepressant-like effect may be attributed at lest partially the flavonoids or the interaction of the active(s) principle(s) present in this plant.Descritores:Baccharis ilimita.

Abstract
In relationship centred medicine perspective it is essential to take into account an ethical principle model for our actions, in a meta-analytical foundational perspective, facing concrete and at the same time complex problems in health care, we have to frame them not in terms of strictly defined principles, either formulate them by general acontextual interpretations or resolve them through abstract procedures.Clinical ethics has been enriched by several contributions that deepen a strict principalist perspective. It is from the observation that the clinic relationship creates, in a space and a time, conditions for the emergence of experiential values of the patient and of the professionals through which you can build a relationship of trust (and not through a process merely procedural), that other ethical questionings emerged in this problematization area (ethics of care, hermeneutics, narrative ethics, responsibility ethics).We describe the way this theoretical and deliberative relational ethical model can be easily applied to different ethical issues in psychiatry practice and research.Relational ethics integrates three basic polarities: creating conditions of personhood authenticity, developing a process of reciprocal mutuality and generating an opportunity of growth, development and enhancement. The hermeneutic helical deliberative process takes always in consideration the context relativity and contingency, the other's perspectives and, by creative co-authorship cooperation, allows the emergence of new possibilities of transformative developmental issues.

Abstract
Autoinflammatory disorders (AIDs) are a subgroup of immune-mediated syndromes that result from a primary dysfunction of the innate immune system. AIDs can be either monogenic or polygenic diseases. Unlike organspecific AIDs, systemic AIDs are characterized by fever and/or elevation of acute-phase reactants. This review aims to describe the most common adult-onset systemic AIDs, focusing mostly on polygenic and mixed-pattern diseases which are expected to be more prevalent in adult patients than monogenic AIDs overall. The literature was searched in Medline database. Organ-specific or childhood-onset systemic AIDs were excluded. AIDs were divided in three distinct groups: mixed-pattern, polygenic and adult-onset monogenic AIDs. Most adult-onset AIDs are polygenic but late-onset disease is not rare among monogenic AIDs such as familial Mediterranean fever (FMF). The diagnosis of systemic AIDs in adults is often delayed due to several factors and sometimes it is only established when amyloidosis or other complications are present. Therefore, it probably makes sense to primarily exclude common AIDs in adult patients with fever of unknown origin (and probably different presentations such as polyserositis) since a high prevalence of adult-onset Still's disease or FMF is usually expected. Colchicine, nonsteroidal anti-inflammatory drugs, steroids, immunosuppressive agents, interleukin-1 inhibitors and tumor necrosis factor antagonists constitute common therapeutic options for systemic AIDs.

Abstract
RESUMO Métodos observacionais subjetivos, como escore de locomoção (EL) e escore de condição corporal (ECC), têm sido amplamente utilizados para avaliação populacional de diferentes graus de claudicação e estado nutricional em bovinos. Este estudo objetivou verificar a associação longitudinal entre o escore de condição corporal e o escore de locomoção em vacas da raça Holandesa submetidas a um regime alimentar semiextensivo. O período experimental compreendeu dois anos de observações, em uma propriedade localizada no sul do Rio Grande do Sul. O grupo experimental foi constituído por 900 vacas lactantes, que foram avaliadas trimestralmente por dinâmica ortopédica pelo EL e do estado metabólico pelo ECC. A coleta desses dados foi realizada por três veterinários treinados. A fim de se verificar a correlação entre variáveis, utilizou-se o programa SAS, por meio do método de correlação de Pearson, para determinar a associação entre as variáveis avaliadas (EL e ECC), com nível de significância de 5%. A distribuição dos diferentes escores de locomoção durante o período foi a seguinte: 57,2% dos animais tiveram o escore de locomoção 1, ou seja, estavam saudáveis em relação ao sistema locomotor. O restante dos animais que apresentou algum grau de dificuldade de locomoção distribuiu-se da seguinte forma, segundo a intensidade: 21,6% dos animais apresentaram EL2, 15,5% deles EL3, 3,5% deles EL4 e 2,2% deles EL5. Quanto ao resultado da correlação, observou-se associação negativa (r= -0,57) entre ECC e EL (P= 0,03), com ECC médio de 2,97±0,33 e EL de 1,35±0,24 durante o período experimental. Portanto, há uma correlação negativa entre o escore de condição corporal e o escore de locomoção em vacas da raça Holandesa submetidas ao regime alimentar semiextensivo.

Abstract
Using a well-designed longitudinal cohort, we aimed to identify cytokines that were protective against malaria and to explore how they were influenced by genetic and immunological factors. 349 Mozambican pregnant women and their newborn babies were recruited and followed up for malaria outcomes until 24 months of age. Six Th1 cytokines in cord blood were screened for correlation with malaria incidence, of which IL-12 was selected for further analyses. We genotyped IL-12 polymorphisms in children/mothers and evaluated the genotype-phenotype associations and genetic effects on IL-12 levels. Maternal IL-12 concentrations were also investigated in relation to Plasmodium infections and cord blood IL-12 levels. Our data showed that high background IL-12 levels were prospectively associated with a low incidence of clinical malaria, while IL-12 production after parasite stimulation had the opposite effect on malaria incidence. IL-12 genotypes (IL-12b rs2288831/rs17860508) and the haplotype CGTTAGAG distribution were related to malaria susceptibility and background IL-12 levels. Maternal genotypes also exhibited an evident impact on host genotype-phenotype associations. Finally, a positive correlation in background IL-12 levels between maternal and cord blood was identified. Thus, cord blood background IL-12 concentrations are important for protecting children from clinical malaria, likely mediated by both genotypes (children&mothers) and maternal immunity.

Abstract
Background Difficulties to disentangle the protective versus exposure role of anti-malarial antibodies hamper the identification of clinically-relevant immune targets. Here, factors affecting maternal IgG and IgMs against Plasmodium falciparum antigens, as well as their relationship with parasite infection and clinical outcomes, were assessed in mothers and their children. Antibody responses among 207 Mozambican pregnant women at delivery against MSP119, EBA175, AMA1, DBLα and parasite lysate (3D7, R29 and E8B parasite lines), as well as the surface of infected erythrocytes, were assessed by enzyme-linked immunosorbent assay and flow cytometry. The relationship between antibody levels, maternal infection and clinical outcomes was assessed by multivariate regression analysis. Results Placental infection was associated with an increase in maternal levels of IgGs and IgMs against a broad range of parasite antigens. The multivariate analysis including IgGs and IgMs showed that the newborn weight increased with increasing IgG levels against a parasite lysate, whereas the opposite association was found with IgMs. IgGs are markers of protection against poor pregnancy outcomes and IgMs of parasite exposure. Conclusions Adjusting the analysis for the simultaneous effect of IgMs and IgGs can contribute to account for heterogeneous exposure to P. falciparum when assessing immune responses effective against malaria in pregnancy.

Abstract
Background Increased susceptibility to malaria during pregnancy is not completely understood. Cellular immune responses mediate both pathology and immunity but the effector responses involved in these processes have not been fully characterized. Maternal and fetal cytokine and chemokine responses to malaria at delivery, and their association with pregnancy and childhood outcomes, were investigated in 174 samples from a mother and child cohort from Mozambique. Peripheral and cord mononuclear cells were stimulated with Plasmodium falciparum lysate and secretion of IL-12p70, IFN-γ, IL-2, IL-10, IL-8, IL-6, IL-4, IL-5, IL-1β, TNF, TNF-β was quantified in culture supernatants by multiplex flow cytometry while cellular mRNA expression of IFN-γ, TNF, IL-2, IL-4, IL-6, IL-10 and IL-13 was measured by quantitative PCR. Results Higher concentrations of IL-6 and IL-1β were associated with a reduced risk of P. falciparum infection in pregnant women (p < 0.049). Pro-inflammatory cytokines IL-6, IL-1β and TNF strongly correlated among themselves (ρ > 0.5, p < 0.001). Higher production of IL-1β was significantly associated with congenital malaria (p < 0.046) and excessive TNF was associated with peripheral infection and placental lesions (p < 0.044). Conclusions Complex network of immuno-pathological cytokine mechanisms in the placental and utero environments showed a potential trade-off between positive and negative effects on mother and newborn susceptibility to infection.

Abstract
OBJECTIVES To assess the prevalence, clinical significance and breed distribution of linear branching mineralisation superimposed on the hepatic radiographic silhouette in dogs. MATERIALS AND METHODS Retrospective review of radiographs or ultrasound images of dogs showing branching mineralisation in the liver. RESULTS Over the 30-year review period, 17 cases were identified and the mineralisation had a predominantly ventral distribution. Seven of the 17 were cavalier King Charles spaniels, and four of the total 17 dogs were diagnosed with hepatobiliary system disease. Five dogs had repeat radiographs, of which four showed no change in the pattern and one developed the pattern 6 years after being diagnosed with cholangiohepatitis. Serum calcium concentrations were normal in all patients. Liver enzymes were markedly elevated only in the dog diagnosed with cholangiohepatitis. Histology performed on three patients showed no convincing evidence of primary liver disease. CLINICAL SIGNIFICANCE Branching mineralisation in the liver parenchyma is a rare finding in dogs with little or no clinical significance and cavalier King Charles spaniels may be predisposed. Biopsy of the liver of affected dogs with no clinical or clinicopathological evidence of liver disease is unlikely to be helpful in these cases.

Abstract
Case report An adult female Australian little red flying fox (Pteropus scapulatus) presented with icterus and anaemia. Examination of a blood smear revealed numerous trypanosomes 20.4–30.8 µm long with tapered ends. Necropsy and histological findings were consistent with trypanosome infection of lymphoid tissue and intravascular haemolysis. Sequence and phylogenetic analysis demonstrated this trypanosome species to be genetically distinct and most similar to Trypanosoma minasense and Trypanosoma rangeli (with a genetic distance of 1% at the 18S rRNA locus for both). Conclusion To the authors’ knowledge this is the first report of a trypanosome infection associated with clinical disease in bats.

Abstract
OBJECTIVES To analyse the influence of epidemiological and sociodemographic factors in complicated alcohol withdrawal syndrome (AWS). MATERIAL AND METHODS A multicentre, observational prospective study was conducted on consecutively added patients with AWS hospitalised in internal medicine departments. We recorded sociodemographic, epidemiological, clinical and progression data. Complicated AWS was defined as that which progressed with seizures or delirium tremens. RESULTS We studied 228 episodes of AWS in 219 patients. The mean age was 54.5 years (SD, 11.5), and 90.8% were men. AWS was the cause for hospitalisation in 39.9% of the patients. Some 27.1% of the cases presented seizures, and 32.4% presented delirium tremens. The daily quantity of alcohol ingested was 17.8 standard drink units (SD, 21.4), with 16.6 years of dependence (SD, 11.3). The pattern of alcohol abuse was regular in 82.8% of the patients. Some 38.4% of the patients were married or had a partner, and 45.6% had children. Some 72.7% of the patients were unemployed or retired. Some 68.5% had only completed primary studies. Some 4.8% consumed cannabis, 5.2% consumed cocaine and 3% consumed opioids. The independent variables related to complicated AWS were consumption of a drug other than alcohol (OR, 5.3; 95% CI 1.5-18.7), low education level (OR, 3.4; 95% CI 1.6-7.3) and hospitalisation for AWS (OR, 2.9; 95% CI 1.5-5.6). The model's receiver operating characteristic area was 0.718 (95% CI 0.643-0.793). CONCLUSIONS Concomitant drug abuse and a low educational level could help identify patients at risk of complicated AWS.

Abstract
The presence of Campylobacter species was studied in three Antarctic penguin species, Adélie (Pygoscelis adeliae), chinstrap (Pygoscelis antarctica) and gentoo (Pygoscelis papua). A total of 390 penguins were captured in 12 different rookeries along the Antarctic Peninsula with differences in the amount of human visitation: six colonies were highly visited [Stranger Point, King George Island (P. papua and P. adeliae); Hannah Point, Livingston Island (P. papua and P. antarctica); Deception Island (P. antarctica); and Paradise Bay, Antarctic Peninsula (P. papua)], and six colonies were rarely visited [Devil's Point, Byers Peninsula, Livingston Island (P. papua); Cierva Cove, Antarctic Peninsula (P. papua); Rongé Island (P. papua and P. antarctica); Yalour Island (P. adeliae); and Avian Island (P. adeliae)]. A total of 23 strains were isolated from penguins from nine different rookeries. Campylobacter lari subsp. lari was isolated from eight samples (seven from P. papua and one from P. adeliae); C. lari subsp. concheus from 13 (ten from P. adeliae and three from P. antarctica) and C. volucris from two samples (both from P. papua). We did not find any significant differences in the prevalence of Campylobacter spp. between the populations in highly and rarely visited areas. This is the first report of C. lari subsp. concheus and C. volucris isolation from penguins in the Antarctic region.

Abstract
The prevalence of psychiatric disturbances in patients with cardiovascular disease is elevated. For example the prevalence of major depression can reach 15–20% and of anxiety disturbances 5–20%.When we treat psychiatric symptoms in cardiovascular disease we must have in mind four particular effects of psychiatric drugs: (1) disturbances of atrial-ventricular conduction; (2) QTc interval prolongation that can lead to torsade de pointes and ventricular fibrillation; (3) hypertension; (4) changes in platelet aggregation.On the other hand, there is a great prevalence of psychiatric disease in patients with renal disease. For example, about 5–25% of the patients with advanced renal disease have major depression.Renal disease patients can evidence changes in several pharmacokinetic parameters such as: (1) biodisponibility; (2) distribution; (3) metabolism; (4) excretion. Therefore, when we treat these patients we have to keep in mind the effect of psychiatric drugs over the renal functioning, but also the effect of the deficient renal function in the pharmacokinetics of the drugs.I this presentation we intend to reveal what are the main concerns when we prescribe psychiatric drugs in patients with cardiovascular and renal disease.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Kernel-based methods have experienced a substantial progress in the last years, tuning out an essential mechanism for data classification, clustering and pattern recognition. The effectiveness of kernel-based techniques, though, depends largely on the capability of the underlying kernel to properly embed data in the feature space associated to the kernel. However, visualizing how a kernel embeds the data in a feature space is not so straightforward, as the embedding map and the feature space are implicitly defined by the kernel. In this work, we present a novel technique to visualize the action of a kernel, that is, how the kernel embeds data into a high-dimensional feature space. The proposed methodology relies on a solid mathematical formulation to map kernelized data onto a visual space. Our approach is faster and more accurate than most existing methods while still allowing interactive manipulation of the projection layout, a game-changing trait that other kernel-based projection techniques do not have.

Abstract
Converging in vitro evidence and clinical data indicate that oxidative stress may play important roles in Plasmodium falciparum malaria, notably in the pathogenesis of severe anaemia. However, oxidative modifications of the red blood cell (RBC)-membrane by 4-hydroxynonenal (4-HNE) and haemoglobin-binding, previously hypothesized to contribute mechanistically to the pathogenesis of clinical malaria, have not yet been tested for clinical significance. In 349 non-immune Mozambican newborns recruited in a double-blind placebo-controlled chemoprophylaxis trial, oxidative markers including 4-HNE-conjugates and membrane-bound haemoglobin were longitudinally assessed from 2·5 to 24 months of age, at first acute malaria episode and in convalescence. During acute malaria, 4-HNE-conjugates were shown to increase significantly in parasitized and non-parasitized RBCs. In parallel, advanced oxidation protein products (AOPP) rose in plasma. 4-HNE-conjugates correlated with AOPP and established plasma but not with RBC oxidative markers. High individual levels of 4-HNE-conjugates were predictive for increased malaria incidence rates in children until 2 years of life and elevated 4-HNE-conjugates in convalescence accompanied sustained anaemia after a malaria episode, indicating 4-HNE-conjugates as a novel patho-mechanistic factor in malaria. A second oxidative marker, haemoglobin binding to RBC-membranes, hypothesized to induce clearing of RBCs from circulation, was predictive for lower malaria incidence rates. Further studies will show whether or not higher membrane-haemoglobin values at the first malaria episode may provide protection against malaria.

Abstract
Background Advanced oxidation protein products (AOPP) are newly identified efficient oxidative stress biomarkers. In a longitudinal birth cohort the effects were investigated of genetic polymorphisms in five oxidative pathway genes on AOPP levels. Methods This study is part of a three-arm randomized, double-blind, placebo-controlled trial. Three hundred and twelve children were included in the present study with AOPP levels measured at 2.5, 5.5, 10.5, 15 and 24 months of age. Twelve polymorphisms were genotyped in five oxidative stress pathway genes: glutathione reductase (GSR), glutamylcysteine synthetase (GCLC), glutathione S-transferase (GST) P1, haem oxygenase 1 (HMOX1) and superoxide dismutase 2 (SOD2) in 298 children. There were 284 children assessed for anaemia and clinical malaria infection at the age of 24 months. Results Two principal components (PCA1 and PCA2) were derived from the AOPP levels measured at the five time points. PCA1 was significantly associated with anaemia (p = 0.0002), and PCA2 with clinical malaria infection (p = 0.047). In the K-Means Cluster Analysis based on levels of AOPP, children were clustered into two groups: Group A (lower AOPP levels) and Group B (higher AOPP levels). The cluster membership was significantly associated with anaemia (p =0.003) as well as with the GSR RS3594 polymorphism (p = 0.037). Mixed linear regression analyses found that the single nucleotide polymorphisms GCLC RS10948751 and HMOX1 RS17885925 were significantly associated with AOPP levels (p = 0.030 and p = 0.027, respectively). Conclusion Plasma AOPP levels were predictive for anaemia and oxidative stress markers for clinical malaria infection in two year old children. Several polymorphisms in GCLC, GSR and HMOX1 genes were associated with oxidative stress status of these children.

Abstract
Background The impact of the age of first Plasmodium falciparum infection on the rate of acquisition of immunity to malaria and on the immune correlates of protection has proven difficult to elucidate. A randomized, double-blind, placebo-controlled trial using monthly chemoprophylaxis with sulphadoxine-pyrimethamine plus artesunate was conducted to modify the age of first P. falciparum erythrocytic exposure in infancy and assess antibodies and malaria risk over two years. Methods Participants (n = 349) were enrolled at birth to one of three groups: late exposure, early exposure and control group, and were followed up for malaria morbidity and immunological analyses at birth, 2.5, 5.5, 10.5, 15 and 24 months of age. Total IgG, IgG subclasses and IgM responses to MSP-119, AMA-1, and EBA-175 were measured by ELISA, and IgG against variant antigens on the surface of infected erythrocytes by flow cytometry. Factors affecting antibody responses in relation to chemoprophylaxis and malaria incidence were evaluated. Results Generally, antibody responses did not vary significantly between exposure groups except for levels of IgM to EBA-175, and seropositivity of IgG1 and IgG3 to MSP-119. Previous and current malaria infections were strongly associated with increased IgG against MSP-119, EBA-175 and AMA-1 (p < 0.0001). After adjusting for exposure, only higher levels of anti-EBA-175 IgG were significantly associated with reduced clinical malaria incidence (IRR 0.67, p = 0.0178). Conclusions Overall, the age of first P. falciparum infection did not influence the magnitude and breadth of IgG responses, but previous exposure was critical for antibody acquisition. IgG responses to EBA-175 were the strongest correlate of protection against clinical malaria. Trial registration ClinicalTrials.gov: NCT00231452.
