Neurodevelopmental disorder associated with gene ARF3: A case report.

We present a case study of a patient exhibiting acquired microcephaly along with global developmental delay and drug-resistant epilepsy. Brain magnetic resonance imaging revealed distinctive features, including a Z-shaped morphology of the brainstem, volumetric reduction of white matter, diffuse thinning of the corpus callosum, and partial fusion of the cerebellar hemispheres at their most cranial portion. Whole-exome sequencing uncovered a pathogenic variant in the ARF3 gene c.200A>T, p.(Asp67Val). The neurodevelopmental disorder associated with the ARF3 gene is exceptionally rare, with only two previously documented cases in the literature. This disorder is characterized by global developmental delay and brain malformations, particularly affecting the white matter, cerebellum, and brainstem. It can also manifest as acquired microcephaly and epilepsy. These phenotypic characteristics align with Golgipathies, underscoring the significance of considering this group of conditions in relevant clinical contexts. In cases where a Z-shaped morphology of the brainstem is observed, ARF3-associated disorder should be included in the list of differential diagnoses.

Effects of superparamagnetic iron oxide nanoparticles (SPIONS) testicular injection on Leydig cell function and sperm production in a murine model.

In the domain of medical advancement, nanotechnology plays a pivotal role, especially in the synthesis of biocompatible materials for therapeutic use. Superparamagnetic Iron Oxide Nanoparticles (SPIONs), known for their magnetic properties and low toxicity, stand at the forefront of this innovation. This study explored the reproductive toxicological effects of Sodium Citrate-functionalized SPIONs (Cit_SPIONs) in adult male mice, an area of research that holds significant potential yet remains largely unknown. Our findings reveal that Cit_SPIONs induce notable morphological changes in interstitial cells and the seminiferous epithelium when introduced via intratesticular injection. This observation is critical in understanding the interactions of nanomaterials within reproductive biological systems. A striking feature of this study is the rapid localization of Cit_SPIONs in Leydig cells post-injection, a factor that appears to be closely linked with the observed decrease in steroidogenic activity and testosterone levels. This data suggests a possible application in developing nanostructured therapies targeting androgen-related processes. Over 56 days, these nanoparticles exhibited remarkable biological distribution in testis parenchyma, infiltrating various cells within the tubular and intertubular compartments. While the duration of spermatogenesis remained unchanged, there were many Tunel-positive germ cells, a notable reduction in daily sperm production, and reduced progressive sperm motility in the treated group. These insights not only shed light on the intricate mechanisms of Cit_SPIONs interaction with the male reproductive system but also highlight the potential of nanotechnology in developing advanced biomedical applications.

Characteristics of Opsoclonus-Myoclonus Syndrome in Patients of the Largest Pediatric Hospital in Latin America.

BACKGROUND: Opsoclonus-myoclonus syndrome (OMS) is a rare neuroinflammatory disorder characterized by ataxia, opsoclonus, and myoclonus. Clinical diagnosis of OMS has been challenging; therefore, we sought to determine the clinical and treatment profiles of patients with OMS at the largest pediatric hospital in Latin America. METHODS: We analyzed the data of patients diagnosed with OMS between 2010 and 2020 at Pequeno Principe Hospital (Brazil) to determine the corresponding clinical profile more accurately. RESULTS: Of the approximately 50,000 visitors to our pediatric neurology department from 2010 to 2020, 10 patients with OMS were observed. Five nontumor cases included three parainfectious and two idiopathic cases. The median time from symptom onset to diagnosis was 34 days. All patients with diagnostic OMS criteria in the idiopathic, nontumor group underwent whole-exome sequencing, with potentially pathogenic mutations identified in two cases. Nine patients were treated with methylprednisolone pulse, followed by oral steroids; eight received one or more intravenous immunoglobulin treatments; and six received azathioprine and cyclophosphamide. Complete symptomatic recovery was observed in only one patient. CONCLUSIONS: OMS diagnosis remains challenging. Diagnostic suspicion is necessary to improve the management of these patients and allow early immunosuppressive treatment. Paraneoplastic etiology is the most prevalent. In idiopathic patients who do not respond to immunosuppressive treatment, tests, such as whole-exome sequencing, may reveal a differential diagnosis. Genetic alterations that increase the risk of tumors may be an important clue to the pathophysiology of OMS.

Psychobehavioral factors and family functioning in mucopolysaccharidosis: preliminary studies.

Introduction: Mucopolysaccharidoses (MPS) constitute a group of progressive and multisystemic inherited metabolic diseases that profoundly affect both the mental health of patients and the wellbeing of their families. This study aims to evaluate the impact of MPS on family functioning and related factors. Methods and results: Twenty-five patients with MPS, including types I (n = 4), II (n = 11), IIIB (n = 2), IVA (n = 3), and VI (n = 5), and their families participated in this study. The mean patient age was 13 years [standard deviation (SD): 7.7 years]. Behavioral and emotional problems were noted in 9.1% of all patients. While the type of MPS did not directly influence mental problems, the presence of neuronal involvement did (p = 0.006). Patients with MPS III exhibited difficulties primarily in emotional areas, conduct, hyperactivity, and peer problems. Importantly, both patients with MPS II and those with MPS III experienced a significant impact on communication [mean scores for communication domain: MPS II, 35.6 (SD: 24.3); MPS III, 35.0 (SD: 22.6)]; poorer communication was directly linked to worse adaptive behavior (p = 0.012), and worse adaptive behavior was associated with lower quality of life (p = 0.001). Quality of life and caregiver burden among family members did not significantly differ across MPS types; however, higher caregiver burden was negatively associated with quality of life (p = 0.002). Concerning family functioning, the most impacted domains included independence, intellectual/cultural orientation, activity/recreation, and expressiveness. Domain scores did not vary based on MPS type, treatment, or neurological involvement. Quality-of-life scores were positively associated with the cultural/intellectual domain score. Conclusion: The impacts of quality of life and family extend beyond clinical characteristics and MPS type, strongly influenced by patient cognition and communication, as well as type of family functioning, especially those with greater cultural/intellectual skills of their family members. A multidisciplinary approach addressing the broader needs of individuals with MPS becomes essential. Techniques aimed at improving communication, including prompt interventions such as speech therapy and augmentative and alternative communication strategies, can contribute to overall family functioning improvement.

Factors associated with interprofessional collaboration in Primary Health Care: a multilevel analysis.

Working with an interprofessional focus is increasingly necessary, in view of the growing complexity of the population's health needs. This study aims to assess interprofessional collaboration and the teamwork climate in primary health care (PHC) and determine whether there is a relationship between these two variables. The AITCS-II instrument was used to measure interprofessional collaboration, while to diagnose teamwork climate, the ECTE instrument was used, a version adapted to the SUS context of the Teamwork Climate Inventory instrument. These two instruments were applied online together with a questionnaire for the sociodemographic characterization of the 544 participants, who belonged to 97 Family Health Strategy (FHS) teams in a Brazilian municipality. The obtained data were submitted to a multilevel analysis. A positive correlation was observed between interprofessional collaboration and three of the four teamwork climate factors. The better the work climate, the better the interprofessional collaboration in the corresponding team, and this characteristic stands out in relation to other individual analyzed characteristics.

Resumo Trabalhar com foco interprofissional é cada vez mais necessário, tendo em vista a crescente complexidade das necessidades de saúde da população. Este estudo tem como objetivo avaliar a colaboração interprofissional e o clima de trabalho em equipe na atenção primária à saúde (APS) e verificar possível relação entre estas duas variáveis. Para mensurar a colaboração interprofissional foi utilizado o instrumento AITCS-II, enquanto para o diagnóstico do clima de trabalho em equipe foi utilizado o instrumento ECTE, versão adaptada para o contexto SUS do instrumento Teamwork Climate Inventory. Esses dois instrumentos foram aplicados on-line juntamente com um questionário para caracterização sociodemográfica dos 544 participantes, pertencentes a 97 equipes da Estratégia Saúde da Família (ESF) de um município brasileiro. Os dados obtidos foram submetidos a uma análise multinível. Foi observada uma correlação positiva entre a colaboração interprofissional e três dos quatro fatores do clima de trabalho em equipe. Quanto melhor o clima de trabalho, melhor a colaboração interprofissional na equipe correspondente, e essa característica se destaca em relação às demais características individuais analisadas.

Brazilian autoimmune encephalitis network (BrAIN): antibody profile and clinical characteristics from a multicenter study.

Background: The frequency of antibodies in autoimmune encephalitis (AIE) may vary in different populations, however, data from developing countries are lacking. To describe the clinical profile of AIE in Brazil, and to evaluate seasonality and predictors of AIE in adult and pediatric patients. Methods: We evaluated patients with possible AIE from 17 centers of the Brazilian Autoimmune Encephalitis Network (BrAIN) between 2018 and 2022. CSF and serum were tested with TBAs and CBAs. Data on clinical presentation, complementary investigation, and treatment were compiled. Seasonality and predictors of AIE in adult and pediatric populations were analyzed. Results: Of the 564 patients, 145 (25.7%) were confirmed as seropositive, 69 (12.23%) were seronegative according to Graus, and 58% received immunotherapy. The median delay to diagnosis confirmation was 5.97 ± 10.3 months. No seasonality variation was observed after 55 months of enrolment. The following antibodies were found: anti-NMDAR (n=79, 54%), anti-MOG (n=14, 9%), anti-LGI1(n=12, 8%), anti-GAD (n=11, 7%), anti-GlyR (n=7, 4%), anti-Caspr2 (n=6, 4%), anti-AMPAR (n=4, 2%), anti-GABA-BR (n=4, 2%), anti-GABA-AR (n=2, 1%), anti-IgLON5 (n=1, 1%), and others (n=5, 3%). Predictors of seropositive AIE in the pediatric population (n=42) were decreased level of consciousness (p=0.04), and chorea (p=0.002). Among adults (n=103), predictors of seropositive AIE were movement disorders (p=0.0001), seizures (p=0.0001), autonomic instability (p=0.026), and memory impairment (p=0.001). Conclusion: Most common antibodies in Brazilian patients are anti-NMDAR, followed by anti-MOG and anti-LGI1. Only 26% of the possible AIE patients harbor antibodies, and 12% were seronegative AIE. Patients had a 6-month delay in diagnosis and no seasonality was found. Findings highlight the barriers to treating AIE in developing countries and indicate an opportunity for cost-effect analysis. In this scenario, some clinical manifestations help predict seropositive AIE such as decreased level of consciousness, chorea, and dystonia among children, and movement disorders and memory impairment among adults.

Brazilian experts' consensus on the treatment of infantile epileptic spasm syndrome in infants.

BACKGROUND: Infantile epileptic spasms syndrome (IESS) is a rare but severe condition affecting children early and is usually secondary to an identifiable brain disorder. It is related to psychomotor deterioration in childhood and epilepsy in adult life. Treatment is challenging as infantile spasms may not respond to most antiseizure medication, and relapse is frequent. OBJECTIVE: To evaluate the literature regarding treatment of IESS and provide a practical guidance to a healthcare system with limited resources. METHODS: An expert committee from the Brazilian Society of Child Neurology reviewed and discussed relevant scientific evidence in the treatment of IESS regarding the drugs available in Brazil. RESULTS: Oral prednisolone and vigabatrin are the most common drugs used as first-line therapy; they are efficient and affordable therapy as both are available in the Brazilian unified health system (SUS, in the Portuguese acronym). Intramuscular adrenocorticotropic hormone (ACTH) presents similar efficacy as oral prednisolone but has a higher cost and is not available in Brazil. Other antiseizure medications such as topiramate, levetiracetam, or benzodiazepines have limited response and are prescribed as adjuvant therapy. If the health service has nutritionists, a ketogenic diet should be implemented for those not responding to hormonal and vigabatrin treatment. Epilepsy surgery is mainly indicated for patients with focal lesions that do not respond to pharmacological therapy. CONCLUSION: Early treatment of IESS with efficient drugs is feasible in our country. Using standard protocols increases the odds of achieving complete cessation in a shorter time and decreases relapse.

ANTECEDENTES: A síndrome do espasmo epiléptico infantil (IESS) é uma condição rara, mas grave, que afeta crianças precocemente e geralmente é secundária a um distúrbio cerebral identificável, estando relacionada a deterioração psicomotora na infância e a epilepsia na vida adulta. O tratamento é desafiador, pois os espasmos infantis podem não responder à maioria dos medicamentos anticrises e as recidivas são frequentes. OBJETIVO: Avaliar a literatura sobre o tratamento de IESS e fornecer uma orientação prática para um sistema de saúde com recursos limitados. MéTODOS: Um comitê de especialistas da Sociedade Brasileira de Neurologia Infantil revisou e discutiu evidências científicas relevantes no tratamento da IESS em relação aos medicamentos disponíveis no Brasil. RESULTADOS: Prednisolona oral e vigabatrina são os fármacos mais comumente usados como terapia de primeira linha; são eficientes e acessíveis, já que ambos estão disponíveis no sistema único de saúde brasileiro (SUS). O ACTH intramuscular apresenta eficácia semelhante à prednisolona oral, mas tem custo mais elevado e não está disponível no Brasil. Outros medicamentos anticonvulsivos, como topiramato, levetiracetam ou benzodiazepínicos, têm resposta limitada e são prescritos como terapia adjuvante. Se o serviço de saúde tiver nutricionista, deve-se implementar dieta cetogênica para aqueles que não respondem ao tratamento hormonal e vigabatrina. A cirurgia de epilepsia é indicada principalmente para pacientes com lesões focais que não respondem à terapia farmacológica. CONCLUSãO: O tratamento precoce da IESS com fármacos eficazes é factível em nosso meio. O uso de protocolos padronizados aumenta as chances de alcançar a cessação completa em um tempo menor e diminui a recaída.

Wet market biosecurity reform: Three social narratives influence stakeholder responses in Vietnam, Kenya, and the Philippines.

In 2020, Covid-19 led to global policy statements promoting bans and reforms to wet markets in Asia and Africa to prevent future pandemics. We conducted a comparative, exploratory qualitative study in 2021 in three countries (Kenya, Vietnam and the Philippines) to understand the social and political dimensions to biosecurity reform at wet markets. This included 60 key informant interviews and rapid ethnographic research in 15 markets, as well as a review of policy documents and online media articles. We found no evidence that the rhetoric of pandemic spillover that emerged in 2020 had any influence on policy or reform efforts apart from those related to Covid-19 infection control. Rather, we identified three main narratives that frame the problem of biosecurity and preferences for reform. The first, a human health narrative, questioned global framings about pandemic risk, viewed markets as sources for food security rather than disease, emphasized the need to strengthen the control of endemic diseases, and conceptualized health through the lens of 'freshness' rather than biomedical categories. A second modernization narrative approached biosecurity as part of a broader process of socio-economic development that emphasized infrastructural gaps, spatial arrangements, cleanliness and a conflict between reform and economic interests. A third narrative centered on local livelihoods and the tension between local market stakeholders and biosecurity and modernization efforts. This final narrative called into question the appropriateness of certain regulations and policies, including bans and closures, emphasized the importance of preserving cultural heritage and highlighted the need for collective political action to resist certain veterinary policies. In conclusion, wet market biosecurity strategies occur in the context of three contrasting narratives that emphasize different aspects of health and risk, and reflect different worldviews and interests. Within this context, there is a need for local government to strengthen market management and biosecurity in ways that enhance the agency of market stakeholders and strengthen local livelihoods and food security as part of a pluralistic and democratic politics.

Predictive factors of genetic diagnosis and real-life impact of next-generation sequencing for children with epilepsy.

OBJECTIVE: Identify the predictive variables of genetic pathogenic results and the impact of test results on epilepsy diagnosis and management. METHODS: Analytical observational design evaluated 130 patients with epilepsy that had performed genetic testing over January 2017 to July 2022. RESULTS: There was a gradual increase in the number of exams performed over the years. The frequency of pathogenic results was 34% (n = 44/130), 8 altered genes with 54% (n = 24/44) of the results. The tests were more positive in patients with developmental delay and/or regression (p = .01). None of the other factors analyzed were associated with higher diagnostic yield. The age at onset of epilepsy brought diagnostic yield to the test (p = .041). Patients with negative genetic test had a reduction in the number of electroencephalograms performed before and after the test (respectively, 3.80 ± 6.37 and .84 ± 1.67; p < .001). SIGNIFICANCE: Facing a large proportion of patients with unexplained epilepsy have a genetic cause a genetic test has the potential to reduce the use of unnecessary diagnostic tests, improve patient outcomes by identifying targeted treatments, and provide families with genetic counseling and risk assessment. But an early genetic testing can be crucial to reach these goals. Even in cases where the genetic test is negative, the study suggests that it still has important implications for patient care and management.

Brain abnormalities, neurodegeneration, and dysosteosclerosis (BANDDOS): new cases, systematic literature review, and associations with CSF1R-ALSP.

CSF1R mutations cause autosomal-dominant CSF1R-related leukoencephalopathy with axonal spheroids and pigmented glia (CSF1R-ALSP) and autosomal-recessive brain abnormalities, neurodegeneration, and dysosteosclerosis (BANDDOS). The former is increasingly recognized, and disease-modifying therapy was introduced; however, literature is scarce on the latter. This review analyzes BANDDOS and discusses similarities and differences with CSF1R-ALSP.We systematically retrieved and analyzed the clinical, genetic, radiological, and pathological data on the previously reported and our cases with BANDDOS. We identified 19 patients with BANDDOS (literature search according to the PRISMA 2020 guidelines: n = 16, our material: n = 3). We found 11 CSF1R mutations, including splicing (n = 3), missense (n = 3), nonsense (n = 2), and intronic (n = 2) variants and one inframe deletion. All mutations disrupted the tyrosine kinase domain or resulted in nonsense-mediated mRNA decay. The material is heterogenous, and the presented information refers to the number of patients with sufficient data on specific symptoms, results, or performed procedures. The first symptoms occurred in the perinatal period (n = 5), infancy (n = 2), childhood (n = 5), and adulthood (n = 1). Dysmorphic features were present in 7/17 cases. Neurological symptoms included speech disturbances (n = 13/15), cognitive decline (n = 12/14), spasticity/rigidity (n = 12/15), hyperactive tendon reflex (n = 11/14), pathological reflexes (n = 8/11), seizures (n = 9/16), dysphagia (n = 9/12), developmental delay (n = 7/14), infantile hypotonia (n = 3/11), and optic nerve atrophy (n = 2/7). Skeletal deformities were observed in 13/17 cases and fell within the dysosteosclerosis - Pyle disease spectrum. Brain abnormalities included white matter changes (n = 19/19), calcifications (n = 15/18), agenesis of corpus callosum (n = 12/16), ventriculomegaly (n = 13/19), Dandy-Walker complex (n = 7/19), and cortical abnormalities (n = 4/10). Three patients died in infancy, two in childhood, and one case at unspecified age. A single brain autopsy evidenced multiple brain anomalies, absence of corpus callosum, absence of microglia, severe white matter atrophy with axonal spheroids, gliosis, and numerous dystrophic calcifications.In conclusion, BANDDOS presents in the perinatal period or infancy and has a devastating course with congenital brain abnormalities, developmental delay, neurological deficits, osteopetrosis, and dysmorphic features. There is a significant overlap in the clinical, radiological, and neuropathological aspects between BANDDOS and CSF1R-ALSP. As both disorders are on the same continuum, there is a window of opportunity to apply available therapy in CSF1R-ALSP to BANDDOS.

Factors related to the waiting time for scheduling an oral biopsy in Brazil: a multilevel analysis.

BACKGROUND: Timely diagnosis of oral cancers is critical, and performing biopsies of oral lesions with suspected malignancy is a crucial step in achieving this goal. The waiting time for the diagnosis may be related to the progression and prognosis of malignant neoplasms. OBJECTIVE: The aim of this observational, cross-sectional, national-level study was to identify the factors associated with the waiting time for scheduling an oral biopsy, based on the identification of its need. METHODS: We used secondary data from the Brazilian public health system, obtained from the 2nd cycle of the National Program to Improve Access and Quality of Dental Specialty Centers (PMAQ-CEO). The study outcome was the waiting time for scheduling an oral biopsy, starting from the identification of the need for the exam. We analyzed individual and contextual variables using multilevel statistical analysis. RESULTS: In 51.8% of DSC the waiting time for scheduling a biopsy was non-immediate; in 58.1% of CEOs, the sum of the weekly workload of dentists working in the Stomatology specialty is up to 20 h per week; in terms of coverage, 67.1% of the CEOs have only municipal coverage and 34.0% are references for up to 12 oral health teams in primary health care; only the coverage variable remained significant in the multivariate model (p < 0.05). Of the contextual variables, none of the variables remained significant (p > 0.05). When these were analyzed together, only the coverage remained significant (p < 0.05); CONCLUSION: Our analysis indicates that the waiting time for scheduling an oral biopsy is longer in CEOs that cover only one municipality and is not related to contextual factors.

Conferências de saúde e a hanseníase: ditos e silenciamentos sobre a doença negligenciada e seus estigmas / Health and leprosy conferences: sayings and silences about the neglected disease and its stigmas

Resumo Vista como um sério problema de saúde pública em diferentes localidades, a hanseníase é marcada por tabus e carregada de estigmas. É uma doença negligenciada e constituída por diversas explicações ao longo da história, que atualizam marcas vivas do passado, inclusive na implementação de políticas públicas. As conferências de saúde são espaços de participação da sociedade na definição de políticas, com o objetivo de impactar o plano de cuidado de diferentes enfermidades. O objetivo deste artigo é compreender a relevância e as perspectivas apontadas às políticas públicas para a atenção às pessoas acometidas por hanseníase presentes nas etapas municipal, estadual e nacional da 16ª Conferência Nacional de Saúde. Trata-se de uma pesquisa documental baseada nos relatórios finais e na esteira do processo ascendente da 16ª Conferência Nacional de Saúde. Os resultados demonstram a falta de visibilidade da hanseníase nos relatórios das etapas municipal e estadual da conferência e, na etapa nacional, o registro tem dupla ênfase, produzir visibilidade sobre a doença e seu contexto, reivindicando atualizar a mobilização social em torno dela e ações de educação permanente voltadas aos trabalhadores.

Abstract Seen as a serious public health problem in different locations, leprosy is marked by taboos and carried by stigma. It is a neglected disease and made up of several explanations throughout history, which update living marks of the past, including in the implementation of public policies. Health conferences are spaces for society to participate in the definition of policies, aiming to impact the care plan of different illnesses. The objective of this article is to understand the relevance and perspectives pointed to public policies for the care of people affected by leprosy present in the municipal, state, and national stages of the 16th National Health Conference. This is a documentary research based on the final reports and in the wake of the ascending process of the 16th National Health Conference. The results show the lack of visibility of leprosy in the reports of the municipal and state stages of the conference and, in the national stage, the record has a double emphasis: producing visibility about the disease and its context, claiming to update social mobilization around it and permanent education actions aimed at workers.

Association of S(+) ketamine, dexmedetomidine and butorphanol for chemical restraint in scarlet macaws (Ara macao) / Associação cetamina S(+), dexmedetomidina e butorfanol na contenção química de araracangas (Ara macao)

The present study aimed at assessing the effects of combining 20 mg/kg S(+) ketamine with 25 µg/kg dexmedetomidine and 0.4 mg/kg butorphanol on the physiological parameters and anesthetic recovery time and score of eight captive scarlet macaw (Ara macao) specimens. These specimens were captured at the Marabá Zoobotanic Foundation (Fundação Zoobotânica de Marabá), Pará, using butterfly and mist nets, and subsequently subjected to the proposed protocol. The following physiological parameters were evaluated: heart rate (HR), respiratory rate (RR), saturation of peripheral oxygen (SpO2), body temperature (BT), and non-invasive blood pressure 5 min after drug administration (M0) and every 10 min thereafter (M1‒M5), with a total of 55 min of analysis of anesthetic effects. Glycemia was measured 5 min after drug administration and every 30 min thereafter. Anesthetic induction and recovery times were also determined. Among the parameters evaluated in this study, both HR and BT significantly decreased throughout the anesthetic period, with the lowest levels at 55 min after drug administration (M5). In contrast, RR did not significantly differ, and all animals remained stable, maintaining an RR close to a mean of 20 ± 8 cpm. Throughout the anesthetic period, SpO2was 92 ± 5%, with no significant difference. The birds remained under spontaneous ventilation and without oxygen supplementation. Systolic, diastolic, and mean blood pressures remained stable, with no significant differences in any of these measurements. At M0 and M3, the glycemia decreased slightly, albeit with no significant difference justifying an adverse effect or even hypoglycemia. The anesthetic induction time, from M0 to decubitus, was 2.4 ± 0.7 min. The anesthetic recovery time, from M0 to effortless bipedal position and adequate phalangeal flexion, was 99.3 ± 32.4 min. The sedation was assessed as intense, and the anesthetic recovery was rated excellent in 62.5% and good in 37.5% of the animals.(AU)

O presente estudo objetivou avaliar os efeitos do uso da cetamina S(+) 20 mg/kg associada à dexmedetomidina 25 µg/kg e butorfanol 0,4 mg/kg sobre os parâmetros fisiológicos, tempo e qualidade da recuperação anestésica de araracangas (Ara macao). Foram utilizados oito espécimes de Ara macao cativas da Fundação Zoobotânica de Marabá, Pará. A captura foi realizada com o uso de puçá e rede de contenção e em seguida as aves foram submetidas ao protocolo proposto. Foram avaliados: frequência cardíaca, frequência respiratória, saturação parcial da oxihemoglobina (SpO2), temperatura corporal e pressão arterial não-invasiva a partir de 5 minutos após a aplicação dos fármacos (M0) e a cada 10 minutos seguintes (M1, M2, M3, M4 e M5), totalizando 55 minutos de contemplação dos efeitos anestésicos. A glicemia foi avaliada aos 5 minutos da aplicação dos fármacos e repetida após 30 minutos. Também foi determinado o tempo de indução e de recuperação. Dentre os parâmetros avaliados, a frequência cardíaca e a temperatura demonstraram queda estatisticamente significativa ao longo do período anestésico, ambas com os menores valores registrados aos 55 minutos após a aplicação dos fármacos (M5). A frequência respiratória não apresentou diferença estatística e todos os animais se mantiveram estáveis e com a frequência próxima a média de 20±8mpm. A saturação da oxihemoblobina (SpO2) ao longo do período anestésico foi de 92±5%, não houve diferença estatisticamente relevante, as aves permaneceram sob ventilação espontânea e sem suplementação de oxigênio. As pressões arteriais sistólica, diastólica e média, mantiveram-se estáveis e não houve diferença estatística para nenhuma dessas medidas. A glicemia, mensurada em M0 e M3 demonstrou queda discreta, sem diferença significativa capaz de justificar um efeito adverso ou mesmo hipoglicemia. O tempo de indução, desde aplicação dos anestésicos até o decúbito, foi de 2,4±0,7 minutos. O tempo de recuperação, compreendido desde a aplicação dos fármacos (M0) até a constatação da posição bipedal sem esforço e adequada flexão das falanges, foi de 99,3±32,4 minutos. A qualidade de sedação foi considerada intensa e a recuperação anestésica foi classificada como ótima para 62,5% e boa para 37,5% dos animais.(AU)

Neurological, neurobehavioral, and radiological alterations in patients with mucopolysaccharidosis III (Sanfilippo's syndrome) in Brazil.

Mucopolysaccharidosis type III (MPS III) or Sanfilippo syndrome is the most common form of MPS, in which neurological involvement in all stages of the disease is prominent. The current study aimed to comprehensively describe the neurological profile of children and adolescents with MPS III who visited the largest pediatric hospital in South America. A prospective/retrospective cohort analysis was performed on 10 patients with MPS III from eight unrelated families. Most patients <12 months of age had achieved development milestones within the expected range for their age, with delay in walking independently and first single word acquisition. Behavioral symptoms were reported in seven patients. Eight patients (80%) developed profound intellectual disabilities. Six patients (60%) had epilepsy, among whom 75% had their first seizure between 2 and 4 years of age; the frequency of which increased with age. Monotherapy was effective in 60% of patients. Two patients, both aged <8 years, had normal baseline electroencephalographic activity. Epileptiform activity was observed in three patients. Cortical atrophy was visualized using magnetic resonance imaging in 71% patients; all but one of these patients were aged >6 years. Neurological abnormalities increased in prevalence and severity with age. Anti-seizure drug resistance was uncommon. Dysmorphological and systemic manifestations were uncommon and mild and did not correlate with neurological involvement. Despite high allelic heterogeneity, neurodegeneration was similar among all patients. Overall, these data contribute to the scarce literature from developing countries.

GIGYF1 disruption associates with autism and impaired IGF-1R signaling.

Autism spectrum disorder (ASD) represents a group of neurodevelopmental phenotypes with a strong genetic component. An excess of likely gene-disruptive (LGD) mutations in GIGYF1 was implicated in ASD. Here, we report that GIGYF1 is the second-most mutated gene among known ASD high-confidence risk genes. We investigated the inheritance of 46 GIGYF1 LGD variants, including the highly recurrent mutation c.333del:p.L111Rfs*234. Inherited GIGYF1 heterozygous LGD variants were 1.8 times more common than de novo mutations. Among individuals with ASD, cognitive impairments were less likely in those with GIGYF1 LGD variants relative to those with other high-confidence gene mutations. Using a Gigyf1 conditional KO mouse model, we showed that haploinsufficiency in the developing brain led to social impairments without significant cognitive impairments. In contrast, homozygous mice showed more severe social disability as well as cognitive impairments. Gigyf1 deficiency in mice led to a reduction in the number of upper-layer cortical neurons, accompanied by a decrease in proliferation and increase in differentiation of neural progenitor cells. We showed that GIGYF1 regulated the recycling of IGF-1R to the cell surface. KO of GIGYF1 led to a decreased level of IGF-1R on the cell surface, disrupting the IGF-1R/ERK signaling pathway. In summary, our findings show that GIGYF1 is a regulator of IGF-1R recycling. Haploinsufficiency of GIGYF1 was associated with autistic behavior, likely through interference with IGF-1R/ERK signaling pathway.

Attributes of primary health care in Mato Grosso do Sul state: PCAT-Brazil paired for users and health professionals, 2018.

OBJECTIVE: The objective of the present study was to analyse the quality of adults and older adults health care in Primary Health Care (PHC) services in the State of Mato Grosso do Sul, 2018. METHODS: A quantitative survey was carried out in which the municipalities participating in the study included the four macro-regions following the Director Regional Plan (DRP). In this study, the quality of care was verified using the validated version of the PCAT-Br for adult and older adults users over 18 years of age and professionals. The professional's and users' views were compared between PHC attributes in the State of Mato Grosso do Sul. We performed the paired student t-test. STATA v.14.2 software (College Station, TX, USA) was used for the analyses. Sensitivity analysis was done to compare socio-demographic characteristics. RESULTS: Eight hundred twenty-five users and 424 professionals participated in the study. According to users, the Accessibility attribute had the worst performance in all macro-regions (mean score PCAT = 3.58). There were significant differences between the perception of users and professionals (PCAT = 5.32 for users and PCAT = 7.11 for professionals) in all attributes evaluated. CONCLUSIONS: There was a difference in users' and professionals' perceptions between PHC attributes. Therefore, it is necessary to strengthen PHC care networks in the State, mainly considering the users' perspectives.

Educação Permanente em Saúde: colocando em análise a produção de conhecimento / Permanent Health Education: analyzing knowledge production

A educação permanente em saúde (EPS) é utilizada como estratégia para a transformação das práticas profissionais e da própria organização do trabalho, instituída através da Política Nacional de Educação Permanente em Saúde (PNEPS) no ano de 2004, tornando-se dispositivo de intervenção institucional. No entanto, apesar de mais de uma década da implantação desta política, observa-se dificuldades quanto à concepção e práticas de EPS no Brasil, com a adoção de práticas tecnicistas e instrumentalizadas nomeadas como EPS. Objetivo: Explorar o contexto teórico da PNEPS desde a sua implantação e o forjamento da concepção de EPS, como uma criação brasileira que carrega os princípios e diretrizes do Sistema Único de Saúde, tendo por campo a Atenção Básica. Método: Foram realizadas buscas na literatura que traziam como tema a educação permanente em saúde e saúde pública, sem restrição quanto ao período de publicação. Conclusões: As produções indicam o uso indiscriminado do conceito de EPS, escolha por nomear EPS ações de educação continuada, desconhecimento da PNEPS por parte de gestores, trabalhadores e usuários. No entanto, é possível observar que não há problematização dos dados coletados, assim como não os coloca em análise histórica, movimento proposto neste ensaio.
