The objectives of this study were to evaluate the cross-cultural measurement equivalence of the Healthy Eating Index (HEI) for children aged 1–2 years and to analyse the quality of nutrition of preterm infants. This was a cross-sectional study with 106 premature infants attended in two specialised outpatient clinics of university hospitals. The quality of the diet was analysed through an adapted HEI to meet the dietary recommendations of Brazilian children aged 1–2 years. Food consumption was measured by 24-h recalls. The reliability of the instrument was evaluated by internal consistency analysis and inter-observer reliability using Cronbach’s α coefficient and κ with quadratic ponderation. The construct validity was evaluated by principal component analysis and by Spearman’s correlation coefficient with total energy and consumption of some groups’ food. The diet quality was considered adequate when the total HEI score was over 80 points. Cronbach’s α was 0·54. Regarding inter-observer reliability, ten items showed strong agreement (κ > 0·8). The item scores had low correlations with energy consumed (r ≤ 0·30), and positive and moderate correlation of fruit (r 0·67), meat (r 0·60) and variety of diet (r 0·57) with total scores. When analysing the overall quality of the diet, most patients need improvement (median 78·7 points), which can be attributed to low total vegetable intake and the presence of ultraprocessed foods in the diet. The instrument showed auspicious psychometric properties, being promising to evaluate the quality of the diet in children aged 1–2 years.

Objectives
Recent evidence has questioned modern psychiatric clinical practice, specifically the prescribing of “atypical” antipsychotics. Our Pan-European Research Group wished to ascertain clinical practice amongst European trainees, which treatments trainees would desire for themselves, and factors influencing this.
MethodsA semi-structured survey was constructed from prior literature, piloted, and a homogenous sample size of at least 50 was agreed upon from each country, with 50% minimum response rate. It was distributed via web-link, with questions on preference of antipsychotic for patients in given scenarios, and factors influencing choice. Physicians were asked for their preference should they develop psychosis.
Resultsi) Treatment choice of antipsychotic for patients
93% (n=600) of respondents chose to prescribe “atypical” antipsychotics (excluding Clozapine), 6% (n=42) choosing “typical” antipsychotics, 1% (n=6) choosing Clozapine as first-line therapy.
ii) Treatment choice if trainees developed psychosis
89% (n=530) of responders chose to prescribe “atypical” antipsychotics (excluding Clozapine), 7% (n=40) choosing “typical” antipsychotics, 4% (n=23) choosing Clozapine as first-line therapy.
iii) Factors influencing choice
These mapped onto three domains: cost, efficacy and side-effect profile (less than 5% other reasons). 79% (n=458) of those who responded felt efficacy most important, 46% (n=270) felt side-effect profile most important and 3% (n=16) considered cost of paramount importance.
38% (n=272) of those who responded to the survey stated that the CATIE trial had influenced their decision-making.
ConclusionsPsychiatry trainees’ choice of antipsychotic medication for both patients and themselves is based on perceived benefits, as opposed to evidence base and recent literature.

Chitosan (CHI) is a natural biopolymer with antimicrobial, anti-inflammatory, antioxidant and digestive modulatory effects, which can be used in the ruminant diet to replace antibiotics. The aim of this study was to evaluate the effects of CHI on lamb growth traits, nutrients digestibility, muscle and fatty deposition, meat fatty acid (FA) profile, meat quality traits and serum metabolome. Thirty 30-month-old male lambs, half Suffolk and half Dorper, with an average BW of 21.65 ± 0.86 kg, were fed in a feedlot system for a total of 70 days. The lambs were separated into two groups according to the diet: the control (CON) group which received the basal diet and the CHI group which received the basal diet with the addition of CHI as 2 g/kg of DM in the diet. Lambs supplemented with CHI had a greater (P < 0.05) final BW, DM intake, final body metabolic weight (P < 0.05) and lower residual feed intake than the CON group. Animals fed CHI had a greater (P < 0.05) starch digestibility at 14 and 28 days, average daily gain at 14, 42 and 56 days, greater feed efficiency at 28 days and feed conversation at 14 and 42 days in feedlot. Most of the carcass traits were not affected (P > 0.05) by the treatment; however, the CHI supplementation improved (P < 0.05) dressing and longissimus muscle area. The treatments had no effect (P > 0.05) on the meat colour and other quality measurements. Meat from the CHI-fed lambs had a greater concentration (P < 0.05) of oleic-cis-9 acid, linoleic acid, linolenic-trans-6 acid, arachidonic acid and eicosapentaenoic acid. According to the variable importance in projection score, the most important metabolites to differentiate between the CON and the CHI group were hippurate, acetate, hypoxanthine, arginine, malonate, creatine, choline, myo-inositol, 2-oxoglutarate, alanine, glycerol, carnosine, histidine, glutamate and 3-hydroxyisobutyrate. Similarly, fold change (FC) analysis highlighted succinate (FC = 1.53), arginine (FC = 1.51), hippurate (FC = 0.68), myo-inositol (FC = 1.48), hypoxanthine (FC = 1.45), acetate (FC = 0.73) and malonate (FC = 1.35) as metabolites significantly different between groups. In conclusion, the present data showed that CHI changes the muscle metabolism improving muscle mass deposition, the lamb’s performance and carcass dressing. In addition, CHI led to an alteration in the FA metabolism, changes in the meat FA profile and improvements in meat quality.

Introduction
Over the last two decades, through the voices of groups including non-governmental organizations, persons bearing sex differentiation disorders have begun to question when and how one should decide in favor of or against surgical intervention following diagnosis.
MethodSemi-structured interviews were held with seven adult patients who showed sex differentiation disorders at birth: Two with 5-alpha-reductase type-2 deficiency and five with congenital adrenal hyperplasia.
ObjectivesTo investigate both how sexual identity is structured and the relationship between sexual identity, choice of sex object and sexual difference.
DiscussionThere is no ideal moment to perform surgical reassignment interventions on intersex patients, since the depth of the trauma can be neither predicted nor avoided. Traumatic events and their numerous occurrences are overdetermined, and depend on how parents, medical teams and subjects themselves cope with them throughout life. This fact is closely related to the question of how and when to operate, and who makes any decision to operate in order to “normalize” “abnormal” sex organs. The subject should never be left out of this decision.
This most complex discussion involves many variegated factors, including X and Y chromosomes, testosterone levels, hormone receptor sensitivities, sexual practices, the gender of partners, mannerisms, clothing, accessories, dream content and sexual fantasies, and none of them determine individuals’ identification nor their preferences for this or that sexual object.
ConclusionsSex is trauma. Neither male nor female nor any other gender identification implies the choice of sex object, genders of partners or sexual practices.

Introduction
Hashimoto's encephalopathy is a rare neurological disorder of unknown cause associated with thyroid autoimmunity. The disease may present in two types - a sudden vasculitic type or a progressive subacute type associated to cognitive impairment and psychiatric symptoms.
ObjectivesReport a case of a patient with Hashimoto's encephalopathy presenting with neuropsychiatric symptoms.
AimsHighlight the diagnostic difficulties of medical disorder presenting with clinical features overlapping psychiatric syndromes.
MethodsReview of the scientific literature and patient's clinical notes.
ResultsA 61-year old female without previous psychiatric history was referred to psychiatry consultation for depressive symptomatology in the last year. She was prescribed with antidepressants with some initial overall improvement, but gradually developed, during the next nine months, cognitive impairment with loss of skills to be independent and increasing tremor of the extremities. Neurological evaluation was requested which revealed frontal functions impairment. Blood workup only found increased titers of anti-thyroid antibody. EEG showed mild bitemporal slowing, brain MRI was normal and brain SPECT scan revealed fronto-temporo-parietal hypoperfusion. Hashimoto encephalopathy was presumed and corticoids were started with significant improvement of neuropsycological symptoms and tremor. After one year she remains assymptomatic.
ConclusionsHashimoto's encephalopathy is a diagnosis of exclusion and clinical suspicion is essential for its identification. This unusual disorder is often unrecognized for a long time because of the multiple and protracted neurocognitive manifestations and normal findings in several different examinations.
This case also highlights the importance for close collaboration between psychiatrists and neurologists.

Introduction
Gender dysphoria is incoherence between the sex a person feels or expresses and the biological.
ObjectiveRevise the inclusion criteria for hormone therapy and sex reassignment surgery in gender dysphoria. Expose the multidisciplinary approach. Make differential diagnosis with other psychological disorders.
MethodologyA 45 years old male patient (biological female), who was sent from Endocrinology Unit for a psychiatric evaluation before restart a hormonal treatment. Since his childhood, he has presented dissatisfaction with his sexual characteristics; he has had fantasies and dreams, in which he belonged to the other sex. He has always chosen male activities and male stereotypes companies. He has presented preference for cross-dressing from 9 years. Always felt the sexual attraction for women. He first consulted for this reason in 1995.
ResultsIt reported favorably to start hormone treatment after completing the eligibility criteria: > 18 years old; knowledge of the effects of hormones; and more 3 months documented real-life experience. The hormone therapy caused the growth of microprolactinoma, which was treated with dopamine agonists until it disappeared and the cessation of galactorrhea. Testosterone treatment is restarted. Laboratory tests are done every 3 months during the first year and then, every 6 months.
ConclusionsIs the gender disphoria a pathology? The EU recommends a reclassification as no pathological disorders in ICD-11. The treatment of gender dysphoria is necessary, and there is no reason to postpone it. The main difficulty is the differential diagnosis; there may be comorbidity with others mental disorders which are not exclusive (psychotic disorder, OCD, personality disorders and other disorders of gender identity).

Reducing the risk of human immunodeficiency virus type 1 (HIV-1) transmission is still a public health priority. The development of effective control strategies relies on the quantification of the effects of prophylactic and therapeutic measures in disease incidence. Although several assays can be used to estimate HIV incidence, these estimates are limited by the poor performance of these assays in distinguishing recent from long-standing infections. To address such limitation, we have developed an assay to titrate p24-specific IgG3 antibodies as a marker of recent infection. The assay is based on a recombinant p24 protein capable to detect total IgG antibodies in sera using a liquid micro array and enzyme-linked immunosorbent assay. Subsequently, the assay was optimised to detect and titrate anti-p24 IgG3 responses in a panel of sequential specimens from seroconverters over 24 months. The kinetics of p24-specific IgG3 titres revealed a transient peak in the 4 to 5-month period after seroconversion. It was followed by a sharp decline, allowing infections with less than 6 months to be distinguished from older ones. The developed assay exhibited a mean duration of recent infection of 144 days and a false-recent rate of ca. 14%. Our findings show that HIV-1 p24-specific IgG3 titres can be used as a tool to evaluate HIV incidence in serosurveys and to monitor the efficacy of vaccines and other transmission control strategies.

Globally, the prevalence of tuberculosis (TB) disease is higher in males. This study examined the effect of sex and age on Mycobacterium tuberculosis (Mtb) infection. Demographic and exposure data were collected on household contacts of sputum smear-positive pulmonary TB patients in Brazil. Contacts with tuberculin skin test induration ⩾10 mm at baseline or 12 weeks were considered Mtb infected. The study enrolled 917 household contacts from 160 households; 508 (55.4%) were female, median age was 21.0 years (range 0.30–87.0) and 609 (66.4%) had Mtb infection. The proportion infected increased with age from 63.3% in girls <5 years to 75.4% in women ⩾40 years and from 44.9% in boys <5 years to 73.6% in men ⩾40 years. Multivariable modelling showed the odds of infection increased between age 5 and 14 years among female contacts (OR 1.5 per 5-year age increase; 95% CI 1.1–2.2; P = 0.02) and between ages 0–4 and 15–39 years among male contacts (OR 2.7, 95% CI 0.83–8.9 and 1.1, 95% CI 0.99–1.3 per 5-year age increase; P = 0.10, 0.07, respectively). The study suggests that the age at which Mtb infection increases most is different in females compared with males. Studies are needed to explore whether these findings are due to differences in host susceptibility, exposure outside the household or other factors.

Acinetobacter spp. are important healthcare pathogens, being closely linked to antibiotic resistance and outbreaks worldwide. Although such species are rarely observed in patients with cystic fibrosis (CF), we describe the characteristics of 53 strains of Acinetobacter spp. isolated from the sputum of 39 Brazilian patients with CF. The species distribution was A. baumannii (n = 29), A. pittii (n = 13), A. nosocomialis (n = 8), A. seifertii (n = 1), A. soli (n = 1) and A. variabilis (n = 1) determined by partial rpoB gene sequencing. Sixteen strains (10 A. baumannii, 3 A. pittii and 3 A. nosocomialis) were multidrug-resistant (MDR) by disk diffusion test (30%) and eight MDR carbapenem-resistant A. baumannii strains harboured the blaOXA-23-like oxacillinase gene. Thirty-three sequence types (STs) were identified by multilocus sequence typing of which eight were novel (A. baumannii: 843, 844, 845, 847, 848; A. pitti: 643; A. nosocomialis: 862 and A. seifertii: 846); six STs (2 A. baumannii, 3 A. pittii and 1 A. nosocomialis) were found in more than one patient. Four strains of A. baumannii were assigned to two common clonal complexes (CCs), namely, CC1 (ST1, ST20 and ST160), and CC79 (ST79). This study underlines the extensive species diversity of Acinetobacter spp. strains in CF lung infections which may present difficulties for therapy due to significant antimicrobial resistance.

Background
There has been increasing evidence that chronic low-grade inflammation is associated with mood disorders. However, the findings have been inconsistent because of heterogeneity across studies and methodological limitations. Our aim is to prospectively evaluate the bi-directional associations between inflammatory markers including interleukin (IL)-6, tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hsCRP) with mood disorders.
MethodsThe sample consisted of 3118 participants (53.7% women; mean age: 51.0, s.d. 8.8 years), randomly selected from the general population, who underwent comprehensive somatic and psychiatric evaluations at baseline and follow-up (mean follow-up duration = 5.5 years, s.d. 0.6). Current and remitted mood disorders including bipolar and major depressive disorders (MDD) and its subtypes (atypical, melancholic, combined atypical and melancholic, and unspecified) were based on semi-structured diagnostic interviews. Inflammatory biomarkers were analyzed in fasting blood samples. Associations were tested by multiple linear and logistic regression models.
ResultsCurrent combined MDD [β = 0.29, 95% confidence interval (CI) 0.03–0.55] and current atypical MDD (β = 0.32, 95% CI 0.10–0.55) at baseline were associated with increased levels of hsCRP at follow-up. There was little evidence for inflammation markers at baseline predicting mood disorders at follow-up.
ConclusionsThe prospective unidirectional association between current MDD subtype with atypical features and hsCRP levels at follow-up suggests that inflammation may be a consequence of this condition. The role of inflammation, particularly hsCRP that is critically involved in cardiovascular diseases, warrants further study. Future research that examines potential influences of medications on inflammatory processes is indicated.

This study assessed the incidence and risk factors for dengue virus (DENV) infection among children in a prospective birth cohort conducted in the city of Recife, a hyperendemic dengue area in Northeast Brazil. Healthy pregnant women (n = 415) residing in Recife who agreed to have their children followed were enrolled. Children were followed during their first 24 months of age (May/2011–June/2014), before the 2015 Zika virus outbreak. DENV infection was detected by reverse-transcriptase polymerase chain reaction and/or serology (anti-DENV IgM/IgG). The incidence rates per 1000 person-years (py) and its association with risk factors by age bands (0–12, >12–30 months) were estimated through Poisson regression models. Forty-nine dengue infections were detected; none progressed to severe forms. The incidence rates were 107·6/1000py (95% CI 76·8–150·6) and 93·3/1000py (95% CI 56·1–154·4) in the first and second years of age, respectively. Male children (risk ratios (RR) = 2·33; 95% CI 1·09–4·98) and those born to DENV-naïve mothers (RR = 2·42; 95% CI 1·01–5·80) were at greater risk of infection in the first year of age. In the second year, children born to Caucasian/Asian descent skin colour mothers had a threefold higher risk of infection (RR = 3·34; 95% CI: 1·08–10·33). These data show the high exposure of children to DENV infection in our setting and highlight the role of biological factors in this population's susceptibility to infection.

Achromobacter spp. are opportunistic pathogens increasingly recovered from adult patients with cystic fibrosis (CF). We report the characterization of 122 Achromobacter spp. isolates recovered from 39 CF patients by multilocus sequence typing, virulence traits, and susceptibility to antimicrobials. Two species, A. xylosoxidans (77%) and A. ruhlandii (23%) were identified. All isolates showed a similar biofilm formation ability, and a positive swimming phenotype. By contrast, 4·3% and 44·4% of A. xylosoxidans and A. ruhlandii, respectively, exhibited a negative swarming phenotype, making the swimming and swarming abilities of A. xylosoxidans significantly higher than those of A. ruhlandii. A. xylosoxidans isolates from an outbreak clone also exhibited significantly higher motility. Both species were generally susceptible to ceftazidime, ciprofloxacin, imipenem and trimethoprim/sulphamethoxazole and there was no significant difference in susceptibility between isolates from chronic or sporadic infection. However, A. xylosoxidans isolates from chronic and sporadic cases were significantly more resistant to imipenem and ceftazidime than isolates of the outbreak clone.

Lipid droplets (LD) in porcine oocytes form a dark mass reaching almost all cytoplasm. Herein we investigated changes in fat areas, cytoplasmic tone and LD morphology during in vitro maturation (IVM) of porcine oocytes cultured with 100 μM trans-10, cis-12 conjugated linoleic acid (t10,c12 CLA) or 10 μM forskolin at different time periods. Four groups were constituted: control, excipient, t10,c12 CLA and forskolin, with drugs being supplemented during 44 to 48 h and the initial 22 to 24 h in Experiments 1 and 2, respectively. In Experiment 3, forskolin was supplemented for the first 2 h. Matured oocytes were inseminated with frozen-thawed boar semen and cleavage rate recorded. Before and during IVM, samples of oocytes were evaluated for LD, total and fat areas and fat gray value or for meiotic progression. Results showed that forskolin supplementation during 44 to 48 h or 22 to 24 h inhibits oocyte maturation (exp. 1: forskolin = 5.1 ± 8.0%, control = 72.6 ± 5.0%; exp. 2: forskolin = 24.3 ± 7.4%, control = 71.6 ± 5.6%) and cleavage (exp. 1: forskolin = 0.0 ± 0.0%, control = 55.4 ± 4.1%; exp. 2: forskolin = 8.3 ± 3.3%, control = 54.5 ± 3.0%). Forskolin also reduced oocyte and fat areas. In Experiment 3, forskolin negative effect on oocyte maturation and cleavage disappeared, although minor (P ⩽ 0.03) LD and oocyte fat areas were identified at 22 to 24 h of IVM. Oocytes supplemented with t10,c12 CLA during 44 to 48 h presented a lighter (P ⩽ 0.04) colour tone cytoplasm than those of control and forskolin. In conclusion, t10,c12 CLA and forskolin were capable of modifying the distribution and morphology of cytoplasmic LD during porcine oocyte maturation, thus reducing its lipid content in a time-dependent manner.

An ATP diphosphohydrolase (EC 3.6.1.5) activity was identified in a Leishmania (Viannia) braziliensis promastigotes preparation (Lb). Ultrastructural cytochemical microscopy showed this protein on the parasite surface and also stained a possible similar protein at the mitochondrial membrane. Isolation of an active ATP diphosphohydrolase isoform from Lb was obtained by cross-immunoreactivity with polyclonal anti-potato apyrase antibodies. These antibodies, immobilized on Protein A-Sepharose, immunoprecipitated a polypeptide of approximately 48 kDa and, in lower amount, a polypeptide of approximately 43 kDa, and depleted 83% ATPase and 87% of the ADPase activities from detergent-homogenized Lb. Potato apyrase was recognized in Western blots by IgG antibody from American cutaneous leishmaniasis (ACL) patients, suggesting that the parasite and vegetable proteins share antigenic conserved epitopes. Significant IgG seropositivity in serum samples diluted 1:50 from ACL patients (n=20) for Lb (65%) and potato apyrase (90%) was observed by ELISA technique. Significant IgG antibody reactivity was also observed against synthetic peptides belonging to a conserved domain from L. braziliensis NDPase (80% seropositivity) and its potato apyrase counterpart (50% seropositivity), in accordance with the existence of shared antigenic epitopes and demonstrating that in leishmaniasis infection the domain r82-103 from L. braziliensis NDPase is a target for the human immune response.

Caliciviruses cause rabbit haemorrhagic disease (RHD) that kills more than 90% of the infected adult animals within 1 a 3 days of infection. The virus replicates in the liver and causes a fulminant hepatitis in adult rabbits leading to RHD. A mystery of the calicivirus infection is that young rabbits (less than 8-weeks old) are resistant to the infection, in spite of undergoing viral replication in the liver and of expressing transient hepatitis. Heterophils were the predominant inflammatory cells seen in hepatic tissue of infected adult rabbits, whereas mononuclear cells dominated the inflammatory infiltrates of the infected young rabbits (4-weeks-old). In order to define the role of inflammation in the pathogenesis of the calicivirus infection, we have studied the cellular inflammatory response in young rabbits experimentally infected by calicivirus. For this, we have used transmission electron microscopy (TEM) and flow cytometry to identify the inflammatory cells that infiltrate the hepatic tissue of young rabbits at 48 hours of calicivirus infection. In same infected rabbits, lymphoid organs (spleen and thymus) were used to quantify by flow cytometry the total number of leukocytes seen inside these organs.

Evolutionary and closer structural relationships are demonstrated by phylogenetic analysis, peptide prediction and molecular modelling between Solanum tuberosum apyrase, Schistosoma mansoni SmATPase 2 and Leishmania braziliensis NDPase. Specific protein domains are suggested to be potentially involved in the immune response, and also seem to be conserved during host and parasite co-evolution. Significant IgG antibody reactivity was observed in sera from patients with American cutaneous leishmaniasis (ACL) and schistosomiasis using potato apyrase as antigen in ELISA. S. mansoni adult worm or egg, L. braziliensis promastigote (Lb) and Trypanosoma cruzi epimastigote (EPI) have ATP diphosphohydrolases, and antigenic preparations of them were evaluated. In ACL patients, IgG seropositivity was about 43% and 90% for Lb and potato apyrase, respectively, while IgM was lower (<19%) for both. In schistosomiasis patients IgM (>40%) or IgG (100%) seropositivity for both soluble egg (SEA) and adult worm (SWAP) antigens was higher than that found for potato apyrase (IgM=10%; IgG=39%). In Chagas disease, IgG seropositivity for EPI and potato apyrase was 97% and 17%, respectively, while the IgM was low (3%) for both antigens. The study of the conserved domains from both parasite proteins and potato apyrase could lead to the development of new drug targets or molecular markers.
