RESUMO
Necrotic enteritis (NE) is a disease of worldwide distribution, which affects young broilers and causes economic losses on a scale of 6 billion dollars per year. For decades, NE was controlled in poultry flocks by dietary administration of low doses of antimicrobial growth promoters (AGPs). However, an increase in NE incidence was noted after the AGP ban. This study aimed to compare the effect of an antibiotic (Enramycin) diet to a combination of sodium butyrate, hydrolyzed yeast, and zinc proteinate (ViligenTM) on broiler diets regarding performance, blood parameters, intestinal permeability, morphology and lesions, and carcass yield of broilers challenged with Eimeria spp. and Clostridium perfringens to simulate subclinical necrotic enteritis. A total of 1,150 one-day-old male broiler chickens with an initial average weight of 43.9 ± 0.65 g were allocated to 50 experimental pens. Animals were divided into 5 groups: Negative control (NC) without additives; Positive control (PC) with 0.12 g/ton of Enramycin (8%); V500, V1000, and V1500 with the addition of 500, 1.000, and 1.500 g/ton of Viligen, respectively. All animals were challenged by Eimeria spp. at 7 d of age and by C. perfringens at 17, 18, and 19 d for induction of subclinical NE. The broilers fed with all concentrations of Viligen showed similar performance, blood parameters, intestinal permeability, and carcass yield compared to PC broilers. However, NC broilers showed higher FCR compared to PC broilers from 1 to 33 d (1.42 vs. 1.39) (P = 0.048) and from 1 to 42 d (1.51 vs. 1.49) (P < 0.001). V1500 broilers had fewer intestinal lesions at 28 d when compared to the PC treatment (P < 0.05) and showed that higher Viligen inclusion resulted in lower intestinal damage. At 21 d, the V500 group showed higher intestinal morphology characteristics (VH:VD 4.9 vs. 3.5) compared to the PC treatment (P < 0.001). Thus, in this study, the dietary addition of Viligen to broilers challenged by an experimental model of subclinical NE resulted in lower intestinal damage and similar performance to that obtained by the addition of Enramycin.

OBJECTIVE/AIM: The absence of a comprehensive understanding of potential anaphylactic reactions to local anesthetics (LAs) and management can result in grave consequences. For this reason we aim to assess Latin American dentists' knowledge, preparedness, and competency in managing anaphylactic reactions to LAs. MATERIALS AND METHODS: Design: A cross-sectional study was conducted from November 2021 to February 2022. Board-certified dentists answered a survey comprising 26 structured questions. Chi-square tests and logistic regression models were performed in Stata 17.0. SETTING: Argentina, Brazil, Colombia, Costa Rica, Ecuador, Honduras, Mexico, Peru, Venezuela, and other Latin American countries. RESULTS: Of 507 respondents, lidocaine was the most frequently used LA (88.1%). While 85.2% could identify dyspnea as a symptom of anaphylaxis, only 50.1% knew the correct route for epinephrine administration, and just 43.5% had epinephrine in their emergency kits. Confidence in managing anaphylactic reactions was low (9.6%). Older age was inversely related to both knowledge of anaphylaxis management and the possession of epinephrine (P = 0.003 and P = 0.0001, respectively). DISCUSSION: Our study highlights a concerning discrepancy between the practical readiness of Latin American dentists in handling anaphylaxis. CONCLUSION: The study's findings underscore the need for educational interventions to improve the readiness to identify and handle anaphylactic emergencies in dental practice.
RESUMO
Abstract: Since May 2020, we have been conducting a comprehensive study to understand the natural history of SARS-CoV-2 infection in Rio de Janeiro, Brazil. Our focus has been on following families, systematically collecting respiratory tract swabs and blood samples, monitoring symptoms, and gathering data on vaccine status. This paper aims to describe the household cohort across five epidemic waves of SARS-CoV-2, providing an overview of the collected data and a description of the epidemiological, clinical, and immunological characteristics and incidence of SARS-CoV-2 infection. Our cohort includes 691 participants from 189 households. During the five epidemic waves, we detected 606 infections. The incidence density of SARS-CoV-2 infection ranged from 4 (Delta) to 56 (B.1.1.33) per 1,000 person-week, with a peak in wave B.1.1.33 in all age groups. The seroprevalence of SARS-CoV-2 antibodies (IgG anti spike protein) varied from 37%, in the pre-VoC period, to 99%, in the Omicron period, progressively increasing after each wave in a similar manner regardless of age. As we have monitored the cohort continuously since the beginning of the pandemic, we were able to collect data across different scenarios according to the predominant lineage in circulation. Via active monitoring of families, we were able to carry out an epidemiological surveillance on SARS-CoV-2, including its variants, persistence of symptoms, and changes in immunity over time in the population, contributing to knowledge of the natural history of SARS-CoV-2 infection.
Resumo: Desde maio de 2020, temos conduzido um estudo abrangente para entender a história natural da infecção por SARS-CoV-2 no Rio de Janeiro, Brasil. Nosso foco tem sido acompanhar as famílias das quais coletamos sistematicamente amostras de sangue e do trato respiratório, monitoramos os sintomas e reunimos dados sobre o status de vacinação. Este artigo tem como objetivo descrever a coorte de domicílios ao longo de cinco ondas epidêmicas de SARS-CoV-2, fornecendo uma visão geral dos dados coletados e uma descrição das características epidemiológicas, clínicas e imunológicas e da incidência da infecção por SARS-CoV-2. Nossa coorte inclui 691 participantes de 189 domicílios. Ao longo das cinco ondas epidêmicas, detectamos 606 infecções. A densidade de incidência da infecção por SARS-CoV-2 variou de 4 (Delta) a 56 (B.1.1.33) a cada 1.000 pessoas por semana e foi mais alta na onda B.1.1.33 em todas as faixas etárias. A soroprevalência de anticorpos contra o SARS-CoV-2 (proteína IgG anti-spike) variou de 37% no período pré-VoC a 99% no período Omicron e aumentou onda após onda de maneira semelhante, independentemente da idade dos participantes. Como monitoramos a coorte continuamente desde o início da pandemia, pudemos coletar dados em diferentes cenários, de acordo com a cepa predominante em circulação. Por meio do monitoramento ativo das famílias, conseguimos conduzir uma vigilância epidemiológica do SARS-CoV-2, de suas variantes, da persistência dos sintomas e das mudanças na imunidade da população ao longo do tempo, contribuindo para o conhecimento da história natural da infecção pelo SARS-CoV-2.

ABSTRACT Objective: To describe nurses' perceptions of cancer patient care in Primary Health Care. Method: A qualitative study was conducted in 26 Family Health Centers in a municipality in western Santa Catarina - Brazil, between September and October 2022. A total of 33 nurses took part and completed an online questionnaire. The text was interpreted based on the conceptual precepts of organizational culture from Chiavenatto's administrative theory. The frequency of responses analyzed objective questions; the Collective Subject Discourse was used for the essay questions. Results: Nurses perceive themselves as unprepared and identify a lack of protocols and organizational flows. Final considerations: In primary Health Care, there is a belief consolidated in everyday work and becomes part of the organizational culture of health services, that cancer patients should go on to specialist care. There is a lack of knowledge of health policies, which implicates professionals in caring for cancer patients.

RESUMO
The main objective of this study was to investigate the dynamic of SARS-CoV-2 viral excretion in rectal swab (RS), saliva, and nasopharyngeal swab (NS) samples from symptomatic patients and asymptomatic contacts. In addition, in order to evaluate the replication potential of SARS-CoV-2 in the gastrointestinal (GI) tract and the excretion of infectious SARS-CoV-2 from feces, we investigated the presence of subgenomic nucleoprotein gene (N) mRNA (sgN) in RS samples and cytopathic effects in Vero cell culture. A prospective cohort study was performed to collect samples from symptomatic patients and contacts in Rio de Janeiro, Brazil, from May to October 2020. One hundred and seventy-six patients had samples collected at home visits and/or during the follow up, resulting in a total of 1633 RS, saliva, or NS samples. SARS-CoV-2 RNA was detected in 130 (73.9%) patients who had at least one sample that tested positive for SARS-CoV-2. The presence of replicating SARS-CoV-2 in RS samples, measured by the detection of sgN mRNA, was successfully achieved in 19.4% (6/31) of samples, whilst infectious SARS-CoV-2, measured by the generation of cytopathic effects in cell culture, was identified in only one RS sample. Although rare, our results demonstrated the replication capacity of SARS-CoV-2 in the GI tract, and infectious viruses in one RS sample. There is still a gap in the knowledge regarding SARS-CoV-2 fecal-oral transmission. Additional studies are warranted to investigate fecal or wastewater exposure as a risk factor for transmission in human populations.

OBJECTIVES: To characterize a novel acquired MBL, BIM-1, in a Pseudomonas #2 (subgroup P. guariconensis) strain isolated from the Aurá river located in the Brazilian Amazon hydrographic basin. METHODS: WGS using an Illumina® MiSeq System was used to characterize the genome of Pseudomonas sp. IEC33019 strain. Southern blotting/hybridization assays were performed to confirm the location of the MBL-encoding gene, blaBIM-1 (Belém Imipenemase). Antimicrobial susceptibility testing, cloning, and biochemical and phenotypic characterization were performed to determine BIM-1 kinetics. RESULTS: The IEC33019 strain showed high resistance rates to ß-lactams, ciprofloxacin and aminoglycosides, being susceptible only to polymyxins and susceptible, increased exposure to aztreonam. WGS analysis revealed a novel acquired MBL-encoding gene, blaBIM-1, found as a gene cassette inserted into a class 1 integron (In1326) that also carried qnrVC1 and aadA11e. In1326 was located in a complex transposon, Tn7122, carried by a 52.7 kb conjugative plasmid (pIEC33019) with a toxin/antitoxin system (vapB/vapC). BIM-1 belongs to the molecular subgroup B1 and shares 70.2% and 64.9% similarity with SIM-1 and IMP-1, respectively. Kinetics analysis of BIM-1 showed hydrolytic activity against all ß-lactams tested. CONCLUSIONS: BIM-1 is a novel acquired MBL encoded by a gene carried by mobile genetic elements, which can be transferred to other Gram-negative bacilli (GNB). Because the IEC33019 strain was recovered from a river impacted by a populous metropolitan region with poor basic sanitation and served by limited potable freshwater, it would be important to establish the role of the BIM-1-producing GNB as nosocomial pathogens and/or as colonizers of the riverside population in this geographical region.

O consumo alimentar atual, caracterizado pelo aumento da ingestão de alimentos de alta densidade calórica e baixo valor nutricional pode influenciar negativamente no estado nutricional e surgimento de agravos à saúde. Este estudo teve como objetivo avaliar a qualidade da dieta e fatores associados em pacientes adultos e idosos atendidos num ambulatório de nutrição. Trata-se de um estudo transversal realizado de maio a outubro de 2021 no ambulatório de nutrição do Instituto de Medicina Integral Prof. Fernando Figueira em Recife, Pernambuco. Foram coletadas as informações do perfil sociodemográfico e econômico, estilo de vida, variáveis clínicas e estado nutricional, no momento do atendimento nutricional (primeira consulta e/ou consulta de acompanhamento). A avaliação do consumo alimentar foi realizada por meio da análise do Índice de Qualidade da Dieta Revisado (IQDR). A amostra foi composta por 102 pacientes, e foi evidenciada uma maior frequência de excesso de peso/obesidade e risco cardiovascular muito elevado. Com relação ao IQDR, 72,6% da amostra apresentam dieta saudável. O tempo de acompanhamento foi correlacionado positivamente com a qualidade da dieta (ρ 0,199; p<0,045); e quanto à glicemia de jejum, houve uma correlação negativa com o consumo de cereais totais (ρ -0,229; p<0,050), e positiva com o consumo de leite e derivados (ρ0,265; p<0,023). No que se refere às variáveis antropométricas, evidenciou-se correlações negativas com o consumo de hortifrútis e cereais integrais. O consumo alimentar é considerado complexo e necessita da avaliação dos fatores que possam interferir no mesmo. O acompanhamento nutricional, a modificação e a melhora da qualidade da alimentação, favorecem à adoção de um estilo de vida mais saudável, relacionando-se com a prevenção e/ou o controle das doenças crônicas não transmissíveis e suas complicações.
Current food consumption, characterized by increased intake of high-density foods and low nutritional value can negatively influence nutritional status and the emergence of health problems. This study aimed to evaluate the quality of the diet and associated factors in adult and elderly patients treated in a nutrition outpatient clinic. This is a cross-sectional study conducted from May to October 2021 at the Nutrition Outpatient Unit of the Fernando Figueira Institute of Integral Medicine in Recife, Pernambuco. The information of the sociodemographic and economic profile, lifestyle, clinical variables, and nutritional status was collected at the time of nutritional consultation (first consultation and/or follow-up consultation). The evaluation of food consumption was performed through the analysis of the Diet Quality Index - Revised (DQI-R). The sample consisted of 102 patients, and there was a higher frequency of overweight/obesity and very high cardiovascular risk. Regarding DQI-R, 72.6% of the sample has a healthy diet. The follow-up time was positively correlated with the quality of the diet (ρ 0.199; p <0.045); and regarding fasting blood glucose, there was a negative correlation with the consumption of total cereals (ρ -0.229; p <0.050) and a positive correlation with the consumption of milk and derivatives (ρ 0.265; p <0.023). Regarding anthropometric variables, negative correlations with the consumption of whole grains and cereals was demonstrated. Food consumption is considered complex and requires the evaluation of factors that may interfere with it. Nutritional monitoring, modifying, and improving the quality of food, favors the adoption of a healthier lifestyle, which relates to the prevention and/or control of chronic non-communicable diseases and their complications.
RESUMO
Introducción: La satisfacción estudiantil con los programas académicos es importante en la educación médica, para crear futuros galenos competentes. No hay estudios latinoamericanos multicéntricos que determinen sus factores asociados, pare mejorar el currículo médico. Objetivo: Determinar el porcentaje y factores asociados a la satisfacción estudiantil con docentes, infraestructura e investigación en 9 escuelas médicas latinoamericanas. Métodos: Estudio transversal descriptivo de datos secundarios obtenidos mediante cuestionario administrado a estudiantes de medicina de 9 universidades latinoamericanas; indagó variables socioeducativas y la satisfacción estudiantil respecto a docentes, infraestructura e investigación de las universidades. Para el análisis se usaron modelos lineales generalizados. Resultados: De 2 649 encuestados, 57 % eran mujeres con mediana de 22 años. Menos del 50 % estuvo satisfecho con infraestructura e investigación; solo frente a docencia hubo 66 % de satisfacción; Colombia fue el de mayor satisfacción con los docentes, con 82 % de encuestados satisfechos, mientras que Chile fue el país más satisfecho respecto a la infraestructura e investigación universitaria, con 67 % y 68 %, respectivamente. Estudiar en universidad privada se asoció a satisfacción con docentes (p= 0,002), infraestructura (p= 0,001) e investigación (p= 0,018), esta última mayor en mujeres (p= 0,033), pero menor en quienes sentían que les alcanzaba el dinero del mes (p= 0,001). Conclusiones: La satisfacción médico-estudiantil en universidades latinoamericanas tiende hacia la baja, están más satisfechos los de universidades privadas, tienen mayor satisfacción frente a la investigación las mujeres y menor quienes sienten que les alcanza el dinero hasta fin de mes.
Introduction: Student satisfaction with academic programs is important in medical education to create future competent doctors. There are not multicenter Latin American studies that determine its factors related, to improve medical curricula. Objective: To determine the percentage and factors associated with student satisfaction with teachers, infrastructure, and research in 9 Latin American medical schools. Methods: Descriptive cross-sectional study of secondary data obtained through an administered questionnaire to medical students from 9 Latin American universities between 2016-2017, which inquired about socio-educational variables and student satisfaction regarding teachers, infrastructure, and university research. Generalized Linear Models-GLM was used for the analysis. Results: Of 2 649 surveyed, 57% were women, the median was 22 years. Less than 50% were satisfied with infrastructure and research, only compared to teaching there was 66% satisfaction, Colombia ranking as the one with the highest satisfaction with teachers, with 82% of satisfied respondents, while Chile was the most satisfied country regarding infrastructure and university research with 67% and 68%, respectively. Studying at a private university was associated with teacher satisfaction (p= 0.002), infrastructure (p= 0.001) and research (p= 0.018), the latter was higher in women (p= 0.033), but lower in those who felt that the money of the month was reaching them (p= 0.001). Conclusions: Medical-student satisfaction with Latin American universities is tending downward, with those studying at private universities being more satisfied, women having greater satisfaction with research and less for those who feel that they have enough money until the end of the month.
RESUMO
Las enfermedades orales son las más comunes de las enfermedades crónicas y uno de los problemas más importantes de salud pública debido a su prevalencia, su impacto en los individuos y la sociedad y el costo de su tratamiento. En el caso de los niños este efecto se multiplica por las consecuencias que se derivan para la edad adulta. El objetivo de este estudio fue estimar los índices ceo-d en niños escolares de 5 a 8 años en la Unidad Educativa "Alejandro Dávalos Calle", Ecuador. Para ello, bajo una investigación exploratoria, descriptiva, no experimental, de campo y de corte transversal. Se seleccionó como población los niños entre 5 y 8 años de edad en el periodo académico 2017-2018; la muestra estuvo conformada por 96 niños de ambos sexos, previo a consentimiento informado y cumpliendo las normas de bioéticas. Se realizaron revisión de historia clínica de los infantes y se les aplico encuestas validadas por expertos, a estudiantes, representantes y docentes. Se obtuvo prevalencia a caries en el 100% de los niños, 47% con dientes obturados y 64% perdieron piezas dentales, no se encontró evidencia estadísticamente significativa entre la presencia de caries y el sexo. El CEOD moderado, identificándose como factores de riesgos el desconocimiento de las medidas higiénicas bucal, baja frecuencia en la revisión odontológica y una dieta altamente cariogénica en estos niños. Se recomienda diseñar campañas educativas integrales que oriente a buenas prácticas de higiene bucal con el objetivo de prevenir y minimizar el número de personas afectadas por este mal(AU)
Oral diseases are the most common of the chronic diseases and one of the most important public health problems due to their prevalence, their impact on individuals and society, and the cost of their treatment. In the case of children, this effect is multiplied by the consequences that are derived for adulthood. The objective of this study was to estimate the ceo-d indices in school children aged 5 to 8 years at the "Alejandro Dávalos Calle" Educational Unit, Ecuador. For this, under an exploratory, descriptive, non-experimental, field and cross-sectional investigation. Children between 5 and 8 years of age in the academic period 2017-2018 were selected as the population; The sample consisted of 96 children of both sexes, prior to informed consent and complying with bioethical norms. The infants' clinical history was reviewed and surveys validated by experts, students, representatives, and teachers were applied. Caries prevalence was obtained in 100% of the children, 47% with filled teeth and 64% lost teeth, no statistically significant evidence was found between the presence of caries and sex. The CEOD is high, identifying as risk factors the ignorance of oral hygiene measures, low frequency in dental check-ups and a highly cariogenic diet in these children. It is recommended to design comprehensive educational campaigns that guide good oral hygiene practices in order to prevent and minimize the number of people affected by this disease(AU)

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.33-derived lineage named N.9 was described recently in Brazil and it's considered a potential variant of interest (VOI) due to the presence of E484K substitution at the receptor-binding domain (RBD) of the Spike (S) protein. OBJECTIVE: To describe the first detection of variant N.9 in Rio de Janeiro State. METHODS: SARS-CoV-2 N.9 was confirmed by quantitative reverse transcription polymerase chain reaction (qRT-PCR), whole-genome sequencing and phylogenetic analysis. FINDINGS: Here, we report two SARS-CoV-2 N.9 lineage strains in Rio de Janeiro. One of them had only the E484K substitution of the six N.9 lineage-defining mutations. Other three strains pre-defined as N.9 have the same genomic profile. These four strains are grouped within the B.1.1.33 lineage and basal to the N.9 lineage in our phylogenetic analysis, and we call them "N.9-like/B.1.1.33 + E484K". MAIN CONCLUSIONS: The phylogenetic analysis shows four independent introductions of N.9 in the state of Rio de Janeiro in October and December 2020, January and March 2021. SARS-CoV-2 N.9 dissemination in the Rio de Janeiro could have been limited by the emergence and dominance of other variants, mainly by the lineage P.2 VOI Zeta that emerged in the same period and co-circulated with N.9, as observed in the neighboring State of São Paulo.

This in vitro study evaluated the effect of myristyltrimethylammonium bromide (MYTAB) on the physical, chemical, and biological properties of an experimental dental resin. The resin was formulated with dental dimetacrylate monomers and a photoinitiator/co-initiator system. MYTAB was added at 0.5 (G0.5%), 1 (G1%), and 2 (G2%) wt %, and one group remained without MYTAB and was used as the control (GCtrl). The resins were analyzed for the polymerization kinetics, degree of conversion, ultimate tensile strength (UTS), antibacterial activity against Streptococcus mutans, and cytotoxicity against human keratinocytes. Changes in the polymerization kinetics profiling were observed, and the degree of conversion ranged from 57.36% (±2.50%) for G2% to 61.88% (±1.91%) for G0.5%, without a statistically significant difference among groups (p > 0.05). The UTS values ranged from 32.85 (±6.08) MPa for G0.5% to 35.12 (±5.74) MPa for GCtrl (p > 0.05). MYTAB groups showed antibacterial activity against biofilm formation from 0.5 wt % (p < 0.05) and against planktonic bacteria from 1 wt % (p < 0.05). The higher the MYTAB concentration, the higher the cytotoxic effect, without differences between GCtrl e G0.5% (p > 0.05). In conclusion, the addition of 0.5 wt % of MYTAB did not alter the physical and chemical properties of the dental resin and provided antibacterial activity without cytotoxic effect.
RESUMO
BACKGROUND: Estimation of gestational age (GA) is important to make timely decisions and provide appropriate neonatal care. Clinical maturity scales to estimate GA have used skin texture and color to assess maturity at birth facing situations of the uncertainty of pregnancy dating. The size and darkness of the areola around the nipple to grade skin characteristics are based on visual appearance. The melanin index (M-Index) is an optical skin parameter related to the melanin content in the tissue. This study is aimed to associate the M-Index of the skin with the GA. METHODS: A cross-sectional study evaluated 80 newborns at birth. A photometer device quantified the skin pigmentation on the areolae, forearms, and soles. Paired average differences of M-Index were compared among the three body sites. The skin M-Indexes were compared between subgroups of newborns until 34 weeks or with 34 and more. RESULTS: The skin over the areola had the highest values of M-Index compared with the forearm or sole areas (P < .001 for both). Infants with a GA between 34 and <37 weeks had higher M-Index values over the areola than the group with a GA with 24 to <34 weeks: 41.7 (8.9) and 38.3 (10.5) median (IQR), P = .005. CONCLUSIONS: The measurable M-Index values have the potential to improve physical evaluation in assessing GA at birth.

Resumen Objetivo: Comparar in vitro la microfiltración apical en premolares unirradiculares obturados con cemento a base de resina epóxica y cemento biocerámico. Método: 40 piezas dentales unirradiculares fueron seleccionadas y divididas en dos grupos para ser obturadas esperando el tiempo de fraguado de acuerdo con las instrucciones del fabricante. El grupo A se obturó con cemento biocerámico Endosequence y, el grupo B, con cemento a base de resina epóxica AH-Plus: posteriormente los dos grupos fueron sellados con barniz de uñas hasta 3mm de la parte apical, luego se colocaron las muestras en la incubadora a 37ºC. Ambos fueron sometidos a 750 ciclos de termociclado, para reproducir el ambiente parecido a la cavidad oral. Para análisis de microfiltración se utilizó el método de difusión del colorante, se sumergieron en azul de metileno al 2 % por 6 días, posteriormente los especímenes fueron sometidos en una bomba de vacío. Los dientes fueron cortados longitudinalmente para ser evaluadas mediante el estereomicroscopio. El análisis estadístico fue hecho mediante T-Student y Chi-Cuadrado. Resultados: El grupo A corresponde a Endosequence obtuvo una medida de 0,55mm y el grupo B corresponde a AH-Plus 1,20mm con un estimado de significancia de p=0,013. Conclusión: El análisis de ambos cementos de obturación demostró que Endosequence posee menor microfiltración apical que AH-Plus.
Abstract Aim: To compare in vitro by the stereomiscroscope the lesser apical microfiltration in uniradicular premolars, between the cement based on Epoxy Resin and Bioceramic cement. Method: The study was performed on 40 uniradicular dental pieces divided into two groups, the samples were prepared using the protaper system and the obturation was performed using the lateral condensation technique, the first group was sealed withEndosequence bioceramic cement and the second group with Cement based on AH-Plus epoxy resin, then sealed with nail varnish up to 3mm from the apical part, then the samples were placed in the incubator at 37ºC, waiting for the set time corresponding to each group according to the manufacturer's instructions . The two groups of the present study were submitted to 750 cycles of thermocycling, to provide an environment similar to the oral cavity, then longitudinal cuts were made to the samples. The microfiltration was evaluated using the dye diffusion method, immersed in 2% methylene blue for 6 days, then the specimens were subjected to a vacuum pump. The teeth were cut longitudinally to be evaluated by the stereomicroscope. The statistical analysis was through T-Student and Chi-Square. Results: Group A corresponds to Endosequence obtained a mean of 0,55mm and Group B corresponds to AH-Plus 1,20mm with an estimated significance of p = 0,013. Conclusion: Both obturation cements have significant differences, therefore Endosequence has less apical microfiltration than AHPlus.

The aim of this research was to explore the elements that configure the quality of care among three Mexican same-sex planned families: two female-parented families (through donor insemination) and a male-parented one (through adoption). The first family consisted of two mothers and a 3-year-old daughter; the second one had two mothers and a 1.5-year-old set of boy twins and the third family consisted of two fathers and a 2-year-old girl. It was assumed that Ainsworth's notions of quality of care organization are useful in order to understand caregiver-child attachment relationships, regardless of the parents' sexual orientation. A collective case study was selected due to the fact that these families shared their "unconventionality" (i.e., parents were not heterosexual) and the fact that they were planned, but each one constituted a particular case with a unique configuration. Four trained independent observers used the q-sort methodology (Maternal Behavior Q-Sort and Attachment Q-Sort) to describe parents' and children's behavior, respectively. The findings showed that parents were highly sensitive and all children used them as a secure base. To provide an in-depth examination of which elements configure the quality of care, a semi-structured interview with each parent was carried out. Through a thematic analysis, an over-arching theme named Affections and Emotions was identified, together with six subthemes: (1) Creating an affective environment; (2) Being available; (3) Acknowledging and expressing emotions; (4) Perceiving, interpreting and responding adequately to the child's real self; (5) Taking the child's perspective into account; and (6) Agreeing on roles and dividing the tasks. In order to showcase the particular configuration of gay parenting, the male-headed family narrative is reported in detail, because gay parents have been perceived as violating traditional gender roles as well as the hegemonic model of masculinity. The findings were consistent with the notion of quality of care as proposed by Ainsworth and her collaborators. The implications of the methodological device and research regarding same-sex planned families are discussed so as to understand the organization of the caregiving environment.
RESUMO
Objective: To compare social skills and related executive functions among bipolar disorder (BD) patients with a family history of mood disorders (FHMD), BD patients with no FHMD and healthy control (HCs). Methods: We evaluated 20 euthymic patients with FHMD, 17 euthymic patients without FHMD, and 31 HCs using the Social Skills Inventory (SSI) and a neuropsychological battery evaluating executive function, inhibitory control, verbal fluency and estimated intelligence. Results: Both BD groups had lower SSI scores than controls. Scores for one subfactor of the social skills questionnaire, conversational skills and social performance, were significantly lower among patients with FHMD than among patients without FHMD (p = 0.019). Both groups of BD patients exhibited significant deficits in initiation/inhibition, but only BD patients with FHMD had deficits in verbal fluency, both compared to HC. There were no associations between social skills questionnaire scores and measures of cognitive function. Conclusion: Euthymic BD patients have lower social skills and executive function performance than HC. The presence of FHMD among BD patients is specifically associated with deficits in conversational and social performance skills, in addition to deficits in verbal fluency. Both characteristics might be associated with a common genetically determined pathophysiological substrate.
