RESUMEN

An individual participant data meta-analysis was conducted to test pre-registered hypotheses about how the configuration of attachment relationships to mothers and fathers predicts children's language competence. Data from seven studies (published between 1985 and 2014) including 719 children (Mage : 19.84 months; 51% female; 87% White) were included in the linear mixed effects analyses. Mean language competence scores exceeded the population average across children with different attachment configurations. Children with two secure attachment relationships had higher language competence scores compared to those with one or no secure attachment relationships (d = .26). Children with two organized attachment relationships had higher language competence scores compared to those with one organized attachment relationship (d = .23), and this difference was observed in older versus younger children in exploratory analyses. Mother-child and father-child attachment quality did not differentially predict language competence, supporting the comparable importance of attachment to both parents in predicting developmental outcomes.

RESUMEN

A considerable number of women giving birth during COVID-19 pandemic reported being concerned about changes to their childbirth plans and experiences due to imposed restrictions. Research prior to the pandemic suggests that women may be more at risk of post-traumatic stress symptoms (PTSS) due to unmet expectations of their childbirth plans. Therefore, this study aimed to examine if the mismatch between women's planned birth and actual birth experiences during COVID-19 was associated with women's postpartum PTSS. Women in the postpartum period (up to 6 months after birth) across 11 countries reported on childbirth experiences, mental health, COVID-19-related factors, and PTSS (PTSD checklist DSM-5 version) using self-report questionnaires (ClinicalTrials.gov: NCT04595123). More than half (64%) of the 3532 postpartum women included in the analysis reported changes to their childbirth plans. All changes were significantly associated with PTSS scores. Participants with one and two changes to their childbirth plans had a 12% and 38% increase, respectively, in PTSS scores compared to those with no changes (Exp(ß) = 1.12; 95% CI [1.06-1.19]; p < 0.001 and Exp(ß) = 1.38; 95% CI [1.29-1.48]; p < 0.001). In addition, the effect of having one change in the childbirth plan on PTSS scores was stronger in primigravida than in multigravida (Exp(ß) = 0.86; 95% CI [0.77-0.97]; p = 0.014). Changes to women's childbirth plans during the COVID-19 pandemic were common and associated with women's postpartum PTSS score. Developing health policies that protect women from the negative consequences of unexpected or unintended birth experiences is important for perinatal mental health.

RESUMEN

The purpose of this study was to investigate correlates of preterm (PT) infant's cortisol reactivity and the association to infant negative affect, during a mother-infant interaction procedure. Participants included 48 infants born prematurely (gestational age < 37 weeks) and their mothers, assessed when infants were 12 months old corrected for prematurity. The examined variables comprised both neonatal and environmental dimensions including maternal interactive behavior. Infant negative affect and maternal interactive behavior were assessed with a standardized mother-infant interaction task. A baseline infant saliva sample was collected before the interaction began, and a second sample after the interaction episodes ended. Results revealed that decrease of infant's cortisol concentration was significantly associated with the exposure to more sensitive, and less intrusive maternal behaviors. However, once controlled for neonatal risk, family SES and maternal psychological distress, the associations were rendered non-significant. Although the association between cortisol reactivity and negative affect trended toward significance, maternal intrusiveness was the only significant predictor of observed infant negative affect. Findings suggest the importance of primary relational experiences on PT infants' early regulatory competencies.

RESUMEN

BACKGROUND: One of the most well-documented sequelae of early maltreatment and institutionalisation is attachment problems, including behaviours under the labels of reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED). Despite growing evidence of the neurobiological effects of institutionalisation, the neural correlates of these behavioural patterns are largely unknown. METHODS: The current study examined effects of both institutionalisation in general and attachment disordered behaviour, in particular, on brain-based markers of face processing, in 100 Portuguese children (70 currently institutionalised, 30 continuously raised by their families). Children's neural processing of caregiver's and stranger's faces was assessed with Event-Related Potentials (ERPs). RESULTS: Compared to children from the community, institutionalised children showed smaller amplitudes in the N170, to both stranger and caregiver faces. Amongst the institutionalised group, living in a setting with a higher children-to-caregivers' ratio was associated with smaller P400 amplitudes. The display of DSED symptoms was associated with a smaller P1 to both faces, as well as a reduced differentiation between faces in P400 amplitudes and smaller P400 to the stranger's face. In contrast, RAD symptoms were not associated with any ERP measures. CONCLUSIONS: Results replicate previously reported hypoactivation in institutionalised children, in a less-globally deprived setting than past work, indicating that such a pattern is associated with lack of individualised care and increased symptoms of DSED.

RESUMEN

Mental disorders are commonly featured as chronic conditions with often onset during childhood. In this context, inflammation has been associated with a higher risk of developing physical and mental health problems. Interleukin (IL)-6 is a key mediator of inflammatory responses and plays a pivotal role in immune and nervous system interaction. High levels of IL-6 during childhood are associated with mental problems, indicating that the IL-6 molecular pathway may represent a new target for monitoring and treating these conditions. Here, we report the detection of IL-6 in saliva samples from children (N = 118, mean age 4.4 years old) with behavioral problems using an immunosensor based on electrochemical impedance spectroscopy. This work demonstrates that the proposed immunosensor requires smaller sample volumes and is significantly faster and more sensitive than conventional ELISA while maintaining comparable levels of specificity and reproducibility. The point-of care immunosensor for detection of IL-6 in saliva samples presented herewith is, therefore, an attractive solution to the clinical practice as a rapid non-invasive, high-sensitive monitoring tool of mental health problems, especially in vulnerable patient populations such as children.

RESUMEN

During the postpartum period, the paternal brain suffers extensive and complex neurobiological alterations, through the experience of father-infant interactions. Although the impact of such experience in the mother has been increasingly studied over the past years, less is known about the neurobiological correlates of fatherhood-that is, the alterations in the brain and other physiological systems associated with the experience of fatherhood. With the present study, we aimed to perform a scoping review of the available literature on the genetic, neuroendocrine, and brain correlates of fatherhood and identify the main gaps in the current knowledge. PubMed, Scopus, and Web of Science electronic databases were searched for eligible studies on paternal neuroplasticity during the postpartum period, over the past 15 years. Reference lists of relevant key studies and reviews were also hand-searched. The research team independently screened the identified studies based on the established inclusion criteria. Extracted data were analyzed using tables and descriptive synthesis. Among the 29 studies that met our inclusion criteria, the vast majority pertained to neuroendocrine correlates of fatherhood (n = 19), followed by brain activity or connectivity (n = 7), association studies of candidate genes (n = 2), and brain structure correlates (n = 1). Collectively, studies published during the past 15 years suggest the existence of significant endocrine (testosterone, oxytocin, prolactin, and cortisol levels) and neurofunctional alterations (changed activity in several brain networks related to empathy and approach motivation, emotional processing and mentalizing, emotion regulation, dorsal attention, and default mode networks) as a result of fatherhood, as well as preliminary evidence of genetic variability accounting for individual differences during the postpartum period in fathers. No studies were so far published evaluating epigenetic mechanisms associated with the paternal brain, something that was also the focus of the current review. We highlight the need for further research that examines neuroplasticity during the experience of fatherhood and that considers both the interplay between hormones and simultaneous assessment of the different biomarkers (e.g., associations between hormones and neural activity); data collection protocols and assessment times should also be refined.

RESUMEN

OBJECTIVE: This study examined the quality of interaction between preterm-born preschoolers and their mothers and fathers, focusing on the role of child and parental sex. METHODS: Participants included 88 preterm-born children (<37 wk gestational age) and 44 full-term-born children (≥37 wk gestational age) aged 3 1/2 years and their parents. Mother-child and father-child dyads were observed during a structured interactive task. Children's cooperation-compliance and negativity-hostility behaviors were coded using the Coding System for Mother-Child Interactions, and parents' sensitive behavior was coded using the Ainsworth Sensitivity Scale. RESULTS: There was no association between preterm birth and the quality of child and parents' interactive behaviors. In the full-term group, fathers exhibited lower levels of sensitive behavior than mothers, but in the preterm group, both parents exhibited similar levels of sensitive behavior. Preterm boys exhibited more interactive difficulties than preterm girls, but there was no significant effect of child sex on full-term children's interactive behaviors. Children exhibited more compliance-cooperation and less negativity-hostility toward fathers than toward mothers. CONCLUSION: The findings suggest that prematurity in itself does not affect the quality of parent-preterm child interactive behaviors as the children enter the preschool period. Preterm boys seem to be at higher risk for interactive difficulties than girls, and thus, child sex should be considered when monitoring and examining the development of preterm children.

RESUMEN

The purpose of this study was to investigate the correlates of observed overprotective behaviors of mothers and fathers of preterm-born preschoolers. Participants included 85 children born prematurely (gestational age <37 weeks) and their parents, assessed when children were 12, 24, and 42 months old. Observed overprotection was measured through the standardized observation of a parent-child interaction. The examined correlates included parent-reported perception of their protective behavior, parental gender, child neonatal risk, child development, parent-reported perception of child vulnerability, parent-reported psychological distress, and family's socioeconomic disadvantage. Results revealed that the correlation between parent-reported and observed parental overprotection was not significant for mothers and fathers. There was a significant positive association between maternal and paternal observed overprotection and no significant differences between mothers' and fathers' overprotection levels. Lower child developmental level and more socioeconomic disadvantage at child's 12 months of age were significant predictors of observed overprotective behaviors. Findings suggest the importance of targeting parents of preterm-born children with socioeconomic disadvantages and whose children have a lower developmental level for providing support to both mothers and fathers in the development of more adaptive parenting strategies.

RESUMEN

Based on a meta-analysis, this study aimed to examine cross-informant agreement between parents and teachers about Internalizing, Externalizing and Total Problems in preschool children using community and clinical samples and to test the effects of the type of sample, the measure used for assessments, and child sex on agreement between informants. The meta-analysis involved 23 studies assessing cross-informant agreement for preschool children. Informants were parents and teachers. The level of cross-informant agreement tended to be low. Meta-regression analyses showed that the child's sex, the type of sample, and the measure used for assessments did not predict the level of cross-informant agreement on emotional and behavioural problems. The findings were in line with previous research results. Furthermore, the studied variables did not contribute to the prediction of agreement, suggesting the development of further studies that focus on other variables that may interfere with agreement in informants' reports and will contribute to explaining different ratings of internalizing and externalizing problems in preschool-aged children.

RESUMEN

We investigated biomarkers and genetic modulators of the cerebral vasculopathy (CV) subphenotype in pediatric sickle cell anemia (SCA) patients of sub-Saharan African ancestry. We found that one VCAM1 promoter haplotype (haplotype 7) and VCAM1 single nucleotide variant rs1409419_T were associated with stroke events, stroke risk, as measured by time-averaged mean of maximum velocity in the middle cerebral artery, and with high serum levels of the hemolysis biomarker lactate dehydrogenase. Furthermore, VCAM-1 ligand coding gene ITGA4 variants rs113276800_A and rs3770138_T showed a positive association with stroke events. An additional positive relationship between a genetic variant and stroke risk was observed for ENPP1 rs1044498_A. Conversely, NOS3 variants were negatively associated with silent cerebral infarct events (VNTR 4b_allele and haplotype V) and CV globally (haplotype VII). The -alpha3.7kb-thal deletion did not show association with CV. However, it was associated with higher red blood cell and neutrophil counts, and lower mean corpuscular volume, mean corpuscular hemoglobin and red cell distribution width. Our results underline the importance of genetic modulators of the CV sub-phenotype and their potential as SCA therapeutic targets. We also propose that a biomarker panel comprising biochemical, hematological, imaging and genetic data would be instrumental for CV prediction, and prevention.

RESUMEN

The links between Reactive Attachment Disorder (RAD) and temperament received relatively little research attention, in spite of their clinical and social relevance. Children with RAD sustain disproportionate burdens of early adversity related to their caregiving environment. However, there seem to be important individual differences in susceptibility to adversity, since only a small number of children show signs of RAD. Based on the work of Zeanah and Fox, this review aims to bring new insights to this relevant clinical issue in light of recent research. A differential susceptibility hypothesis will be considered as a promising and innovative approach toward a further understanding of the links between temperament and RAD.

RESUMEN

Analyses of the present data are reported in the article "Crossing Boundaries: A Pilot Study of Maternal Attitudes about Child Maltreatment in Nine Countries" [8]. Data were collected during home visits using the Maltreatment Q-Sort (MQS). A total of 466 mothers from nine different countries gave their opinion about child maltreatment by sorting 90 cards with parenting behaviors taken from the literature that reflect four types of child maltreatment, into 9 evenly distributed stacks (with 10 cards each) from least to most harmful for the child. This data article provides an overview of the content of the 90 items, which type of maltreatment they reflect, and the source of the items. The percentage of mothers labelling each of the MQS items as maltreatment is also presented. In addition, instructions are included about the administration of the MQS as well as data-entry and analyses of Q-sort data, accompanied by example datasets and syntaxes. This can serve as a manual for researchers interested in using Q-sort data.

RESUMEN

INTRODUCTION: Early diagnosis is a crucial tool for containing the human immunodeficiency virus and other sexually transmitted infections, particularly in key populations such as sex workers. Despite its relevance, there is a gap considering epidemiological studies and interventions aimed at the monitoring and diagnosis of sexually transmitted infections in Portugal. The objectives of this study are: (i) to contribute to a better understanding of the epidemiology of sexually transmitted infections; and (ii) to evaluate the transfer of screening methods from clinical settings to the outreach context in hidden populations such as sex workers. MATERIAL AND METHODS: The screening of sexually transmitted infections (human immunodeficiency virus 1/2, hepatitis B virus, hepatitis C virus, syphilis, chlamydia and gonorrhea) were carried out in a sample of 100 sex workers during the Porto G outreach intervention in the Metropolitan area of Porto, from September 2015 to September 2016. RESULTS: Six reactive cases for human immunodeficiency virus were identified, five of syphilis, eight of chlamydia and two of gonorrhea. No positive results were detected for hepatitis B virus and hepatitis C virus. The results were discussed considering the risk gradient and sexually transmitted infections vulnerability in the different sex workers' subgroups. DISCUSSION: The results of this study corroborate the need to promote comprehensive responses to populations most affected by the human immunodeficiency virus and other sexually transmitted infections, such as sex workers. Also, in this group, men who have sex with men and trans women have a higher prevalence than cis women. Intervention strategies should be informed by rigorous epidemiological studies. CONCLUSION: The adaptation of the screening methodology performed in a clinical setting to the proximity context has shown to be an innovative response in Portugal, especially in sentinel populations.


Introdução: O diagnóstico precoce é uma ferramenta incontornável na contenção do vírus da imunodeficiência humana e de outras infeções sexualmente transmissíveis, nomeadamente em populações-chave, das quais fazem parte os/as trabalhadores/as do sexo. Apesar da sua relevância são ainda escassos os estudos epidemiológicos e intervenções que visem a monitorização e diagnóstico das infeções sexualmente transmissíveis em Portugal. Os objetivos do presente estudo são: (i) contribuir para um conhecimento mais aprofundado da epidemiologia de infeções sexualmente transmissíveis e (ii) avaliar a adaptação de métodos de rastreio em meio clínico ao contexto de proximidade em populações ocultas como os/as trabalhadores/as do sexo.Material e Métodos: O rastreio de infeções sexualmente transmissíveis (vírus da imunodeficiência humana 1/2, vírus da hepatite B, vírus da hepatite C, sífilis, clamídia e gonorreia) foi realizado a 100 trabalhadores/as do sexo no âmbito da intervenção de proximidade realizada pelo Porto G na zona Metropolitana do Porto, entre setembro de 2015 e setembro de 2016.Resultados: Foram identificados seis casos reativos para vírus da imunodeficiência humana, cinco de sífilis, oito de clamídia e dois de gonorreia. Não foram detetados resultados positivos para vírus da hepatite B e vírus da hepatite C. Os resultados foram discutidos tendo em conta a gradação de risco e de vulnerabilidade de infeções sexualmente transmissíveis nos diferentes subgrupos de trabalhadores/as do sexo. Discussão: Os resultados deste estudo corroboram a necessidade de promover respostas integradas junto de populações mais afetadas pelo vírus da imunodeficiência humana e outras infeções sexualmente transmissíveis, como são os/as trabalhadores/as do sexo. Também neste grupo, os homens que fazem sexo com homens e as mulheres trans apresentam uma prevalência de vírus da imunodeficiência humana superior à das mulheres cis. As estratégias de intervenção devem ser informadas por estudos epidemiológicos rigorosos.Conclusão: A adaptação da metodologia de rastreio realizada em meio clínico ao contexto de proximidade demonstra ser uma resposta inovadora em território nacional, nomeadamente em populações sentinela.

RESUMEN

The dysregulation of the inflammatory response, including pro-inflammatory molecules, produces neuropsychiatric symptoms and depression-like behavior, including withdrawal from the physical and social environment. Genetic variants that enhance immune reactivity may thus increase inflammatory and withdrawn reactions to stress. Here we investigated a functional polymorphism of Interferon Gamma gene (IFNG +874 T > A, rs2430561) as moderator of the relationship between mothers' distress exposure and children's withdrawn behavior at preschool age. Participants were 198 Portuguese preschool children (mean age = 57.98 months). Exposure to mother's distress was assessed using the Brief Symptom Inventory, and withdrawn behavior with the Caregiver Teacher Report Form. All children provided saliva samples for genotyping. Contrary to expecations based on prior work, the rs2430561 AA genotype-not the T variant-interacted with (high levels of) mothers' distress exposure, to increase children's withdrawn behavior. No significant main effects were detected. The polymorphism in Interferon Gamma gene showed specific environmental stressor-dependent effects on withdrawn behavior during childhood, ones which are interpreted in light of the "behavioral immune system" hypothesis, and which proved inconsistent with diathesis-stress thinking.

RESUMEN

Evidence documenting associations between 5-HTTLPR and parenting behavior led to testing the hypothesis that this polymorphism moderates the effect of the quality of environmental context on maternal sensitivity. Participants were 210 Portuguese mothers and their preschool children, recruited from the community. An index reflecting the quality of the environmental context was derived based on nine markers (e.g. single parenthood; parental education, economic difficulties, family conflict, maternal psychopathology). Maternal sensitivity was measured observationally. Maternal saliva was collected with OraGene kits for genetic analysis. Results revealed a gene-X-environment interaction, such that short-allele homozygotes proved more sensitive to the family context than long-allele carriers (i.e. sL/LL), displaying the highest and lowest levels of maternal sensitivity, depending on, respectively, low and high quality levels of the environmental context. Because even mothers carrying the long allele evinced similar responsiveness to the environmental context, but to a lesser extent, findings proved consistent with the weak differential susceptibility model of person-X-context interaction. Results are discussed in light of prior and related gene-X-environment findings.

RESUMEN

BACKGROUND: Definitions of child maltreatment vary widely between studies, and even more so between different cultural contexts. OBJECTIVE: In this pilot study, we examine between-country variations in maternal notions about what constitutes child maltreatment. PARTICIPANTS AND SETTING: The sample consisted of 466 mothers recruited in Chile, China, Greece, Iran, the Netherlands, Portugal, South Africa, Turkey, and Uruguay. METHODS: All mothers completed a new Q-sort measure, ranking 90 parenting behaviors linked to subtypes of maltreatment (emotional neglect, emotional abuse, physical neglect, and physical abuse) from least to most detrimental to child development. RESULTS: Between-country agreement regarding the harmfulness of the parenting behaviors was high (r = .45), but there were different patterns of reported harmfulness of subtypes of maltreatment (although driven mostly by deviating patterns in the South African sample). Further, there were significant country effects on the number and type of behaviors labeled as maltreatment (pƞ2 = .15), and the number of items labeled as requiring intervention (pƞ2 = .19). CONCLUSIONS: Variations in conceptions of maltreatment need to be studied in larger more representative samples and taken into account in the assessment and treatment of child maltreatment across cultures.

RESUMEN

OBJECTIVE: This meta-analysis tested whether parents of preterm-born children differ from parents of full-term-born children regarding controlling parenting. METHODS: Databases of PubMed, Scopus, Web of Science, Open Access Theses and Dissertations, and Elton B. Stephens Company were searched for cross-sectional and prospective longitudinal studies examining controlling parenting in preterm-born children. RESULTS: The meta-analysis included 27 independent data sets, derived from 34 studies, with a total of 8053 participants-3265 preterm and 4788 full-term children. Parents of children born preterm were more controlling than parents of children born full-term (Hedges' g = 0.29; 95% confidence interval: 0.19-0.39; z = 5.48; p < 0.001). Heterogeneity analysis indicated significant variation in effects between studies (Q = 148.46, p < 0.001), but the effects were not moderated by gestational age, birth weight, child age, child gender, parental education, type of parenting assessment method (observational vs parental self-report), parenting dimension measured (behaviors vs attitudes), type of controlling parenting (intrusiveness vs others), study design (cross-sectional vs longitudinal), year of publication, or geographical setting of the studies (America vs Europe). CONCLUSION: Findings suggest that parents of children born preterm are at higher risk for engaging in controlling parenting strategies, stressing the importance of psychosocial follow-up support for these parents.

RESUMEN

Introdução: O carcinoma de células escamosas é o tumor de maior importância na região de cabeça e pescoço, em razão da sua incidência e mortalidade. Sabe-se que fatores como consumo de álcool estão relacionados à diminuição da sobrevida de tumores tanto estimulando a progressão tumoral como causando comorbidades importantes, sendo um fator relevante para estudo. Objetivo: Avaliar a influência do histórico de álcool em características clinicoprognósticas de pacientes com carcinoma de células escamosas de boca e orofaringe (CCEBO). Método: Estudo de coorte, retrospectivo, no qual 156 prontuários de pacientes etilistas e 78 prontuários de pacientes não etilistas com CCEBO diagnosticados no Hospital Haroldo Juaçaba, em Fortaleza, Ceará, foram avaliados, entre 2000 e 2014, para análise de dados como idade, sexo, raça, localização do tumor, estadiamento TNM, tratamentos realizados e sobrevida em 15 anos por meio dos testes X², Long-Rank e modelos de regressão multinomial e de Cox (SPSS 20,0; p<0,05). Resultados: Houve maior prevalência de homens entre os pacientes etilistas (p<0,001), com tumores T3-T4 (p=0,003), linfonodos positivos (p=0,006) que realizaram tratamentos paliativos (p<0,001) e menor prevalência abaixo de 65 anos (p<0,001), quando havia histórico familiar de câncer (p=0,043). A sobrevida dos pacientes etilistas foi menor (p=0,040) e os fatores que diminuíram a sobrevida de maneira independente foram sexo masculino (p=0,042), estadiamento T3-T4 (p=0,004), metástase linfonodal (p=0,012), idade >65 anos (p=0,035) e localização na língua (p=0,042). O sexo masculino foi independentemente associado ao etilismo (p<0,001). Conclusão: O álcool é um fator de prognóstico em pacientes com CCEBO, mostrando maior prevalência em pacientes T3-T4 e, assim, influenciando negativamente no prognóstico.


Introduction: Squamous cell carcinoma is the most important tumor in the head and neck region, due to its incidence and mortality. It is known that factors as alcohol consumption are related to the decrease of the survival of tumors, either stimulating tumor progression or causing considerable comorbidities, being an important study factor. Objective: Evaluate the influence of alcohol history on clinical and prognostic characteristics of patients with mouth oropharynx squamous cell carcinoma (MOSCC). Method: A retrospective cohort study in which 156 charts of alcoholic patients and 78 medical charts of non-alcoholic patients with MOSCC diagnosed at Haroldo Juaçaba Hospital in Fortaleza, state of Ceará were evaluated between 2000 and 2014 for data analysis such as age, gender and race, tumor location, TNM staging, treatments performed and 15-year survival through X², Long-Rank and Cox and multinomial regression models (SPSS 20.0; p <0.05). Results: Men were more prevalent among alcoholic patients (p <0.001), with T3/4 tumors (p = 0.003), positive lymph nodes (p = 0.006) who submitted to palliative treatments (p<0.001) and lower prevalence under 65 years (p <0.001), when there was a family history of cancer (p = 0.043). The survival of alcoholic patients was lower (p = 0.040) and the factors that independently reduced survival were male sex (p = 0.042), T3-T4 staging (p = 0.004), lymph node metastasis (p = 0.012), age> 65 years (p = 0.035) and tumor in the tongue (p = 0.042). Male sex was independently associated with alcohol consumption (p<0.001). Conclusion: Alcohol is a prognostic factor in patients with MOSCC, showing a higher prevalence in T3-T4 patients and, thus, negatively influencing the prognosis.


Introducción: El carcinoma de células escamosas es el tumor de mayor importancia en la región de cabeza y cuello, debido a su incidencia y mortalidad. Se sabe que factores como el consumo de alcohol están relacionado con la disminución de la supervivencia de tumores tanto estimulando la progresión tumoral, como provocando comorbilidades considerables, siendo un factor de estudio importante. Objetivo: Evaluar la influencia del historial del consumo de alcohol en las características clínicas-pronósticas de pacientes con carcinoma de células escamosas oral y orofaringe (CCEOO). Método: Estudio retrospectivo en el que se evaluaron 156 registros médicos de pacientes consumidores de alcohol y 78 de pacientes no alcohólicos con CCEOO diagnosticados en el Hospital Haroldo Juaçaba, en Fortaleza, Ceará, entre 2000 y 2014, para el análisis de datos como edad, sexo raza, escolaridad, los antecedentes familiares, vínculo matrimonial, registro en el servicio, ubicación del tumor, clasificación de TNM, los tratamientos realizados y la supervivencia durante 15 años a través de las pruebas X² Long-Rank y modelos de regresión multinomial y de Cox (SPSS 20.0; p<0,05). Resultados: Hubo una mayor prevalencia de hombres entre pacientes alcohólicos (p<0,001), con tumores T3-T4 (p=0,003), ganglios linfáticos positivos (p=0,006), y realizó tratamientos paliativos (p<0,001) y menor prevalencia en paciente menores de 65 años (p <0,001); cuando se presentaron antecedentes familiares de cáncer (p=0,043). La supervivencia de los pacientes alcohólicos fue menor (p=0,040); y los factores que disminuyeron la supervivencia de forma independiente fueron hombres (p=0,042); estadificación t3-t4 (p=0,004); metástasis a ganglios linfáticos (p=0,012); edad > 65 años (p=0,035); localización de la lengua (p=0,042). El sexo masculino se asoció independientemente con el consumo de alcohol (p<0,001). Conclusión: El alcohol define el pronóstico en pacientes con CCEOO, muestra una mayor prevalencia en pacientes con T3-T4, por lo tanto, influye negativamente en el pronóstico.

RESUMEN

Moenkhausia melogramma is herein redescribed, based on the examination of the holotype plus additional specimens from the western Amazon basin in Brazil, Colombia, Peru, and Ecuador. Moenkhausia melogramma shares with M. collettii, M. conspicua, M. copei, M. venerei, and M. flava a broad dark longitudinal stripe across the eye, and a well-defined dark stripe on the anal-fin base. It can be promptly distinguished from these species by having two humeral blotches. Additionally, we provide comments on the putative relationships of Moenkhausia melogramma with the aforementioned congeners and the Hemigrammus lunatus species-group.(AU)


RESUMO Moenkhausia melogramma é redescrita com base no exame do holótipo e exemplares adicionais da bacia amazônica ocidental no Brasil, Colômbia, Peru e Equador. Moenkhausia melogramma compartilha com M. collettii, M. conspicua, M. copei, M. venerei e M. flava a presença de uma faixa larga longitudinal escura que atravessa os olhos e uma linha escura bem definida na base da nadadeira anal. Ela pode ser prontamente distinguida dessas espécies por ter duas manchas umerais. Adicionalmente, fornecemos comentários sobre as possíveis relações filogenéticas de Moenkhausia melogramma com as congêneres supramencionadas e com o grupo de espécies Hemigrammus lunatus.

RESUMEN

This study extends research on the effects of institutionalization-by examining the trajectories of cognitive, language and motor development of 64 Portuguese infants and toddlers across the first six months of institutionalization, while determining whether pre-institutional adversities and the stability and consistency of institutional care predict children's development. At time of enrollment, 23.4%, 32.8% and 31.3% of the children were moderately to severely delayed, respectively, in their cognitive, linguistic and motor functioning. Developmental problems persisted after six months of institutionalization. The accumulation of early pre-institutional adversities predicted cognitive and motor limitations at admission to the institutions, but not variation in subsequent development. The stability and consistency of institutional care also failed to predict developmental growth and change. Children who had never lived with their families of origin showed a better language development at enrollment than their counterparts who had lived with their families of origin before institutionalization. Such advantage was followed by a deceleration in language growth after six months of institutional placement. Results are discussed in terms of short- vs. longer-term effects of institutionalization.
