Genetic analysis of osteogenesis imperfecta in a large Brazilian cohort.

INTRODUCTION: Osteogenesis imperfecta (OI) is a genetically and clinically heterogeneous disorder caused by disruption of type I collagen synthesis. Previous Brazilian molecular OI studies have been restricted to case reports or small cohorts. The Brazilian OI Network (BOIN) is a multicenter study collecting clinical OI treatment data from five reference centers in three regions of Brazil. OBJECTIVE: To describe the molecular analysis of a large cohort of OI registered at BOIN. METHODS: Targeted next-generation sequencing (NGS) was performed at a centralized laboratory with the Ion Torrent platform, covering 99.6 % of the coding regions of 18 OI-associated genes. Clinical information was obtained from a clinical database. RESULTS: We included 156 subjects in the molecular analyses. Variants were detected in 121 subjects: 65 (53.7 %) in COL1A1, 42 (34.7 %) in COL1A2, 2 (1.7 %) in IFITM5, one (0.8 %) in CRTAP, three (2.5 %) in P3H1, two (1.7 %) in PPIB, four (3.3 %) FKBP10, one (0.8 %) in SERPINH1, and one (0.8 %) in TMEM38B. Ninety-one distinct variants were identified, of which 26 were novel. Of the 107 variants identified in COL1A1 and COL1A2, 24.5 % cause mild OI, while the remaining 75.5 % cause moderate, severe, or lethal OI, of which 49.3 % are glycine to serine substitutions. A single variant in FKBP10 (c.179A>C; p.Gln60Pro) was found in three unrelated and non-consanguineous participants living in the same geographic area in Northeast Brazil, suggesting a possible founder effect. CONCLUSION: Consistent with the literature, 88.4 % of the subjects had a variant in the COL1A1 and COL1A2 genes, with 10 % inherited in an autosomal recessive manner. Notably, one variant in FKBP10 with a potential founder effect requires further investigation. Data from this large cohort improves our understanding of genotype-phenotype correlations for OI in Brazil.

Associated factors with pseudophakic retinal detachment: Long-term follow-up in a Colombian population.

OBJECTIVE: To identify associated factors with the appearance of pseudophakic retinal detachment in patients with history of cataract surgery. METHODS: Retrospective case-control study of 802 eyes of 783 patients with history of cataract surgery. Cases were patients with pseudophakic retinal detachment (n = 258 eyes), while controls were patients with cataract surgery who did not developed retinal detachment during a 10-year follow-up period (n = 544 eyes). RESULTS: Age at cataract surgery among cases was lower than in the control group (57 ± 13 vs. 67 ± 14 years old, respectively; p < 0.0001). Age at retinal detachment was 59 ± 13 years old (range 6-88) and the time between the cataract surgery and the retinal detachment had a median of 2 years (interquartile range 1-4) with a range of 1 month to 14 years. Associated factors for pseudophakic retinal detachment were younger age (<50 years: adjusted odds ratio [aOR] = 18.03, 95% confidence interval [95%CI] = 5.92-54.87; 50-59 years: aOR = 10.09, 95%CI = 3.37-30.23; and 60-69 years: aOR = 5.48, 95%CI = 1.88-15.93), male sex (aOR = 3.71, 95%CI = 2.54-5.44), anterior vitrectomy (aOR = 3.26, 95%CI = 1.16-9.16), history of retinal detachment in the fellow eye (aOR = 6.95, 95%CI = 3.15-15.31), and intraoperative complications during cataract extraction (aOR = 7.45, 95%CI = 3.54-15.69). CONCLUSIONS: This is the first report of associated factors with pseudophakic retinal detachment in a Colombian population. Surgical complications, sex, and age were found to be associated with retinal detachment. Patients should be aware of these potential risks to make informed decisions about their eye health.

Aislamiento social, tecnología y salud mental

Introducción:hace varios meses el mundo se enfrenta a una situación de confinamiento para librar una intensa batalla relacionada con la COVID-19, causada por el SARS-CoV-2. A raíz de lo que ha representado este aislamiento social ya comienza a visibilizarse los daños a la salud mental de quienes lo enfrentan, principalmente los niños y adolescentes. El uso de la tecnología ha sido una opción para muchos y quienes han abusado de la misma hoy sufren la repercusión psicológica que puede generar cualquier adicción.Objetivo:describir las alteraciones psicológicas de los niños y adolescentes relacionada con el abuso de la tecnología en tiempos de COVID-19.Métodos:se realizó una búsqueda bibliográfica en bases de datos Medline/Pubmed, Elseiver, Scielo y Google académico. Se utilizó descriptores como pandemia, confinamiento, tecnología, adicciones, salud mental.Resultados:la medida de confinamiento en el mundo ha demostrado ser la acción más efectiva contra el SARS-CoV-2. Los niños y adolescentes son los que más problemas psicológicos pueden presentar a raíz de esta medida. El uso y abuso de la tecnología durante el confinamiento exacerba manifestaciones psicopatológicas por la pérdida en el control de los impulsos y la poca capacidad de adherirse a actividades más saludables y placenteras.Conclusiones:el confinamiento genera estrés, esto lleva al abuso de tecnología en los más jóvenes. Los trastornos del sueño, la agresividad, la ira, el pobre control de los impulsos, trastornos alimentarios, ansiedad, hiperactividad que aparecen se relacionan con la pérdida del control de estas conductas riesgos.[AU]

Post-mating gene expression of Mexican fruit fly females: disentangling the effects of the male accessory glands.

Mating has profound physiological and behavioural consequences for female insects. During copulation, female insects typically receive not only sperm, but a complex ejaculate containing hundreds of proteins and other molecules from male reproductive tissues, primarily the reproductive accessory glands. The post-mating phenotypes affected by male accessory gland (MAG) proteins include egg development, attraction to oviposition hosts, mating, attractiveness, sperm storage, feeding and lifespan. In the Mexican fruit fly, Anastrepha ludens, mating increases egg production and the latency to remating. However, previous studies have not found a clear relationship between injection of MAG products and oviposition or remating inhibition in this species. We used RNA-seq to study gene expression in mated, unmated and MAG-injected females to understand the potential mating- and MAG-regulated genes and pathways in A. ludens. Both mating and MAG-injection regulated transcripts and pathways related to egg development. Other transcripts regulated by mating included those with orthologs predicted to be involved in immune response, musculature and chemosensory perception, whereas those regulated by MAG-injection were predicted to be involved in translational control, sugar regulation, diet detoxification and lifespan determination. These results suggest new phenotypes that may be influenced by seminal fluid molecules in A. ludens. Understanding these influences is critical for developing novel tools to manage A. ludens.

Atividade antibacteriana de nanopartículas de polipirrol diante de Staphylococcus aureus isolados de amostras de leite de vacas e cabras com mastite / Antibacterial behavior of polypyrrole nanoparticles against Staphylococcus aureus isolated from cows and goats with mastitis

The aim of the present study was to evaluate the antibacterial behavior of polypyrrole nanoparticles (PPy-NPs) in water against biofilm producer or not S. aureus isolated from cows and goats with mastitis. One hundred and thirty-eight isolates of S. aureus were initially evaluated for biofilm formation by spectrophotometry in microplates. In addition, the minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of PPy-NPs in water for planktonic S. aureus were determined. From the bovine samples analyzed, 5 (4.46%) S. aureus isolates showed a strong biofilm production, 17 (15.18%) moderate production, 36 (32.14%) with weak production and 54 (48.21%) did not produce biofilms. Strains from goats (26) showed no biofilm production in 18 (69.23%) strains and weak biofilm production in 8 (30.76%) strains. The MIC and MBC of S. aureus to PPy-NPs were found in the same concentration (125搭/mL) in all strains tested, regardless of biofilm production or not. This finding provides a new insight into the interaction between PPy-NPs and S. aureus, and will offer potential benefits for the control of mastitis.(AU)

Neurocognitive reorganization of emotional processing following a socio-cognitive intervention in Colombian ex-combatants.

Ex-combatants often exhibit atypical Emotional Processing (EP) such as reduced emphatic levels and higher aggressive attitudes. Social Cognitive Training (SCT) addressing socio-emotional components powerfully improve social interaction among Colombian ex-combatants. However, with narrow neural evidence, this study offers a new testimony. A sample of 28 ex-combatants from Colombian illegal armed groups took part in this study, split into 15 for SCT and 13 for the conventional program offered by the Governmental Reintegration Route. All of them were assessed before and after the intervention with a protocol that included an EP task synchronized with electroencephalographic recordings. We drew behavioral scores and brain connectivity (Coherency) metrics from task performance. Behavioral scores yielded no significant effects. Increased post-intervention connectivity in the delta band was observed during negative emotional processing only SCT group. Positive emotions exposed distinctive gamma band connectivity that differentiate groups. These results suggest that SCT can trigger covert neurofunctional reorganization in ex-combatants embarked on the reintegration process even when overt behavioral improvements are not yet apparent. Such covert functional changes may be the neural signature of compensatory mechanisms necessary to reshape behaviors adaptively. This novel framework may inspire cutting-edge translational research at the crossing of neuroscience, sociology, and public policy-making.

Trinigyrus spp. (Monogenea: Dactylogyridae) from Brazilian catfishes: new species, molecular data and new morphological contributions to the genus.

This study describes two new species, Trinigyrus anthus n. sp. and Trinigyrus carvalhoi n. sp., from gills of Hypostomus spp. from the Upper Paraná River basin, Brazil. Trinigyrus peregrinus is redescribed based on examination of its holotype, paratypes and new material of specimens parasitizing Pterygoplichthys ambrosettii, also from the Upper Paraná River basin, Brazil. New morphological features were included in the diagnosis of the genus, such as the presence of a sclerotized border on the anchor base, and a weakly sclerotized fringe on the base of the male copulatory organ (MCO). Trinigyrus anthus n. sp. differs from other congeners by the shape of the MCO, presenting an enlarged base with sclerotized fringes resembling flower petals. Trinigyrus carvalhoi n. sp. and T. peregrinus are similar but can be differentiated from each other mainly by the sclerotization of the vagina (absent in the new species), and the morphology of the MCO (C-shaped versus one counterclockwise circle, respectively). For the first time, gene sequences of Trinigyrus spp. from Brazil were obtained (partial ribosomal 28S and mitochondrial cytochrome c oxidase I (mtCOI)). The genetic divergences among the new species and T. peregrinus varied from 2 to 3% (6‒18 pb) based on sequences of 28S ribosomal DNA (rDNA), and 6-7% (83‒92 pb) using mtCOI. Phylogenetic analyses based on partial 28S rDNA revealed that Trinigyrus, Heteropriapulus and Unilatus formed a monophyletic and well-supported clade of monogeneans from Neotropical freshwater loricariids, suggesting a closer relationship among these dactylogyrids and their hosts.

Elevada frequência de Aeromonas spp. e genes de virulência em cultivos de tilápia-do-nilo (Oreochromis niloticus) em tanques-rede, na região semiárida de Pernambuco, Brasil / High frequency of Aeromonas spp. and virulence genes in Nile Tilapia farms (Oreochromis niloticus) in semi-arid regions of Pernambuco, Brazil

Objetivou-se avaliar a ocorrência de Aeromonas spp. em peixes e amostras de água na região semiárida de Pernambuco e avaliar a frequência de aerolissina (aerA), enterotoxina citotóxica (act), enterotoxina citotônica (alt) e serina protease (ahp) nesses isolados. Foram analisados 70 peixes vivos e oito mortos com sinais clínicos de aeromoniose e 16 amostras de água. Aeromonas spp. foram identificadas por análises microbiológicas (provas bioquímicas) e molecular, usando-se primers específicos para a região 16S rRNA, e a distribuição dos quatro fatores de virulência (aerA, alt, act e ahp) foi investigada por ensaio de PCR. Cento e cinquenta e cinco (84,7%) isolados foram confirmados como Aeromonas spp. na análise molecular. Os genes de virulência mais frequentes foram act (53,55%) e aerA (51,61%). De acordo com o tipo de amostra, observou-se maior frequência do gene aerA (87,5% P=0,0474) em isolados de peixes mortos e a menor frequência do gene act (47,73% P=0,0002) em peixes vivos. Este estudo demonstrou a presença de aeromoniose no cultivo de tilápias em tanques-rede, nos municípios de Jatobá e Petrolândia, na região semiárida de Pernambuco. A detecção de aerA, act e alt pode ser utilizada na tipagem de virulência de Aeromonas spp.(AU)

The purpose of this study was to evaluate the occurrence of Aeromonas spp. from fishes and tilapia net-cage farm water in semi-arid regions of Pernambuco and to evaluate the frequency of the aerolysin (aerA), cytotoxic enterotoxin (act), cytotonic enterotoxin (alt) and serine protease (ahp) genes in Aeromonas isolates. 70 live and eight dead fish with aeromoniosis clinical signs and 16 water samples were analyzed. Aeromonas spp. isolated were identified by microbiological (biochemical evidence) and molecular analysis using specific primers for 16SrRNA region, while the distribution of four virulence factors, including aerA, alt, act and ahp, was investigated by PCR assay. One hundred fifty-five (84.7%) isolates were confirmed as Aeromonas spp. by molecular analysis. The most frequent virulence genes in isolates were act (53.55%) and aerA (51,61%). According to the kind of sample, the higher frequency of aerA gene (87.5% P= 0.0474) was observed in isolates from dead fish and the lowest frequency of act gene (47.73% P= 0.0002) from live fish. This study found the presence of aeromoniosis on tilapia farming in net-cages on Jatobá and Petrolândia counties in the semiarid Pernambuco region. The detection of aerA, act and alt can be used for virulence typing of Aeromonas spp. isolates.(AU)

A Multicentric Brazilian Investigative Study of Copy Number Variations in Patients with Congenital Anomalies and Intellectual Disability.

Genomic imbalances are the most common cause of congenital anomalies (CA) and intellectual disability (ID). The aims of this study were to identify copy number variations (CNVs) in 416 patients with CA and ID from 5 different genetics centers within 4 different states by using the Multiplex Ligation-dependent Probe Amplification (MLPA) technique and to apply the chromosomal microarray (CMA) methodology in selected cases. The samples were analyzed by MLPA kits P064, P036, P070 and P250. Positive results were found in 97/416 (23.3%) patients. CMA was applied in 14 selected cases. In 6/14 (42.85%) patients, CMA detected other copy number variations not detected by the MLPA studies. Although CMA is indispensable for genotype refinement, the technique is still unfeasible in some countries as a routine analysis due to economic and technical limitations. In these cases, clinical evaluation followed by karyotyping and MLPA analysis is a helpful and affordable solution for diagnostic purposes.

Phylodynamics of classical swine fever virus with emphasis on Ecuadorian strains.

Classic swine fever virus (CSFV) is a Pestivirus from the Flaviviridae family that affects pigs worldwide and is endemic in several Latin American countries. However, there are still some countries in the region, including Ecuador, for which CSFV molecular information is lacking. To better understand the epidemiology of CSFV in the Americas, sequences from CSFVs from Ecuador were generated and a phylodynamic analysis of the virus was performed. Sequences for the full-length glycoprotein E2 gene of twenty field isolates were obtained and, along with sequences from strains previously described in the Americas and from the most representative strains worldwide, were used to analyse the phylodynamics of the virus. Bayesian methods were used to test several molecular clock and demographic models. A calibrated ultrametric tree and a Bayesian skyline were constructed, and codons associated with positive selection involving immune scape were detected. The best model according to Bayes factors was the strict molecular clock and Bayesian skyline model, which shows that CSFV has an evolution rate of 3.2 × 10-4 substitutions per site per year. The model estimates the origin of CSFV in the mid-1500s. There is a strong spatial structure for CSFV in the Americas, indicating that the virus is moving mainly through neighbouring countries. The genetic diversity of CSFV has increased constantly since its appearance, with a slight decrease in mid-twentieth century, which coincides, with eradication campaigns in North America. Even though there is no evidence of strong directional evolution of the E2 gene in CSFV, codons 713, 761, 762 and 975 appear to be selected positively and could be related to virulence or pathogenesis. These results reveal how CSFV has spread and evolved since it first appeared in the Americas and provide important information for attaining the goal of eradication of this virus in Latin America.

Quality of life in mucopolysaccharidoses: construction of a specific measure using the focus group technique.

OBJECTIVE: To describe the perceptions of patients, their caregivers, and their healthcare providers to the development of a new specific instrument for assessment of the quality of life (QoL) in patients with mucopolysaccharidoses (MPS) using a qualitative focus group (FG) design. FGs were held in two Brazilian states (Rio Grande do Sul and Rio de Janeiro). RESULTS: Three versions of the new instrument were developed, each for a different age group: children (age 8-12 years), adolescents (age 13-17), and adults (age ≥ 18). The FGs mostly confirmed the relevance of items. All FGs unanimously agreed on the facets: School, Happiness, Life Prospects, Religiosity, Pain, Continuity of Treatment, Trust in Treatment, Relationship with Family, Relationship with Healthcare Providers, Acceptance, and Meaning of Life. The overall concept of QoL (as proposed by the WHO-World Health Organization) and its facets apply to this patient population. However, other specific facets-particularly concerning clinical manifestations and the reality of the disease-were suggested, confirming the need for the development of a specific QoL instrument for MPS.

Assessment of ecosystem health disturbance in mangrove-lined Caribbean coastal systems using the oyster Crassostrea rhizophorae as sentinel species.

This investigation was aimed at contributing to develop a suitable multi-biomarker approach for pollution monitoring in mangrove-lined Caribbean coastal systems using as sentinel species, the mangrove cupped oyster, Crassostrea rhizophorae. A pilot field study was carried out in 8 localities (3 in Nicaragua; 5 in Colombia), characterized by different environmental conditions and subjected to different levels and types of pollution. Samples were collected in the rainy and dry seasons of 2012-2013. The biological effects at different levels of biological complexity (Stress-on-Stress response, reproduction, condition index, tissue-level biomarkers and histopathology) were determined as indicators of health disturbance, integrated as IBR/n index, and compared with tissue burdens of contaminants in order to achieve an integrative biomonitoring approach. Though modulated by natural variables and confounding factors, different indicators of oyster health, alone and in combination, were related to the presence of different profiles and levels of contaminants present at low-to-moderate levels. Different mixtures of persistent (As, Cd, PAHs) and emerging chemical pollutants (musk fragrances), in combination with different levels of organic and particulate matter resulting from seasonal oceanographic variability and sewage discharges, and environmental factors (salinity, temperature) elicited a different degree of disturbance in ecosystem health condition, as reflected in sentinel C. rhizophorae. As a result, IBR/n was correlated with pollution indices, even though the levels of biological indicators of health disturbance and pollutants were low-to-moderate, and seasonality and the incidence of confounding factors were remarkable. Our study supports the use of simple methodological approaches to diagnose anomalies in the health status of oysters from different localities and to identify potential causing agents and reflect disturbances in ecosystem health. Consequently, the easy methodological approach used herein is useful for the assessment of health disturbance in a variety of mangrove-lined Caribbean coastal systems using mangrove cupped oysters as sentinel species.

Brazilian version of the Care Transitions Measure: translation and validation.

AIM: To translate, adapt and evaluate psychometric properties of the complete (15 items) and reduced (three items) versions of the Care Transitions Measure into Brazilian Portuguese. INTRODUCTION: The Care Transitions Measure assesses the quality of care transitions, from the perspective of patients. As accomplishing effective transitions is a challenge to healthcare systems, the instrument provides an opportunity to assess care transitions and improve quality initiatives. METHODS: A three-phased design was used for cross-cultural adaptation, pre-testing and evaluation of psychometric properties of the measurement in a Brazilian hospital. After forward translation, back translation and expert committee review, patients evaluated the instrument in a pre-test. Psychometric testing included face and content validity, reliability, stability and factorial analysis. RESULTS: Cross-cultural adaptation was completed successfully with a high clarity rate. Internal consistency was good in the 15-item version and was moderate in the three-item version. Test-retest reliability showed good stability of the two versions over time. The three-item version had satisfactory criterion validity. Four factors were extracted for the 15-item measure. LIMITATIONS: Samples were restricted to a group of patients from one hospital in southern Brazil. Future studies should test the measurement's construct and predictive validity. CONCLUSIONS: The translated version of the Care Transitions Measure has good face and content validity, reliability and stability. It has shown to be a valid measurement for evaluating the quality of care transitions in Brazil. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Results are beneficial for nurses, managers and policy makers for evaluating care transitions and support the need for changes in policies and practices.

First record of Hysterothylacium sp. Moravec, Kohn et Fernandes, 1993 larvae (Nematoda: Anisakidae) infecting the ornamental fish Hyphessobrycon eques Steindachner, 1882 (Characiformes, Characidae).

This study reports for the first time infection with Hysterothylacium sp. larvae in the ornamental fish Hyphessobrycon eques from the Paranapanema River, Jurumirim Reservoir, São Paulo State, Brazil. A sample of 33 specimens of H. eques was collected in October, 2011. Four specimens of H. eques were parasitized by Hysterothylacium sp. larvae in the intestine and coelomic cavity, with prevalence of 12.1%, mean intensity of infection of 1, and mean abundance of 0.121 ± 0.05. A total of 40 unidentified free-living nematodes were found in the stomach content of 17 fish. This fish species is introduced in the Paranapanema River. Invasive species may affect the native fauna given the introduction of pathogens and parasites. This study also complements data on the diet of H. eques due to the records of free-living nematode as part of the stomach content. Infections with Hysterothylacium sp. larvae may affect the biology of this fish and bring about profit losses to aquarists.
