Introduction The socio-demographic profile of pregnant women in low- and middle- income countries is characterized by low educational attainment and unemployment, leading to social and economic morbidity. characterized by limited opportunities for education, employment, and marriage, which are strongly related to the stigmatization of the disease. The study of the socio- profile and obstetric outcomes of pregnant women with epilepsy in Alagoas, Brazil, may help understand this scenario and facilitate the development of public policy strategies to reduce local morbidity. Objectives We aimed to describe the sociodemographic profile of pregnant women with epilepsy and obstetric outcomes in Alagoas, Brazil. Methods This cohort study was based on medical records of pregnant women with epilepsy in Brazilian high-risk maternity hospitals from 2008 to 2020. The following data were collected: age, race, education, marital status, occupation, number of pregnancies, delivery, and abortion. The inclusion criteria were pregnant women with and without epilepsy (control group) aged < 40 years. Results The prevalence of PWWE was 0.49% (n = 224/44,917). Cesarean delivery was more frequent in PWWE than in pregnant women without epilepsy (adjusted odds ratio [OR] = 22.0; 95% confidence interval [CI] = 14.35–33.73; p<0,01). Abortion was associated with PWWE (OR adjusted = 1.72; 95% CI = 1.13–2.61; p = 0.01). Pregnant women in the countryside were more likely to develop epilepsy than those born in the capital (OR = 1.55; 95% CI = 1.12–2.14; p <0.01). Conclusion The PWWE socio-demographic profile of the Alagoas had a predominance of brown- colored skin, single status, homemakers, and illiteracy with a high proportion residing in the interior of the state. The obstetrics data show a higher incidence of cesarean deliveries and miscarriages.

In this systematic review, we aimed to identify the impact of the COVID-19 pandemic on children/adolescents with a diagnosis of autism spectrum disorder (ASD). The protocol was registered on PROSPERO CRD42021255848. Articles were selected from PubMed, Embase, and LILACS according to these characteristics: patients from zero to 18 years old, exposed to the COVID-19 pandemic, impact on social communication/interaction and restricted/repetitive behavior domains. The Newcastle–Ottawa Scale was used to assess methodological quality and the risk of bias. Of the 351 articles initially identified, 26 were finally included with information on 8,610 patients. Although the studies were heterogeneous, they indicated that the pandemic-related issues experienced by patients with ASD were mostly manifested in their behavior and sleep patterns.

Background: Cerebral palsy is a group of disorders arising from a static damage or brain development defects occurring during fetal life and in the first months of life. Methods: The sample consisted of 800 individuals living in 50 districts of the city of Maceio. A standardized questionnaire was applied. Results: The prevalence of cerebral palsy in the sample was 5/1000. All were born at term, 75% were male, 50% had severe cerebral palsy and 50% was moderate. 75% had quadriplegia and 25% had diplegia. Fifty percent of the cerebral palsy was caused by meningitis and 50% for prolonged labor. Conclusions: The prevalence of cerebral palsy in Maceió is 140.38% higher than the highest prevalence found in developed countries, predominantly in low-income and related to postnatal infection in families.

Objective: This study aimed to investigate the circadian typology of medical students at public universities from one of the northeastern states in Brazil, active in the morning and afternoon shifts, checking the compatibility between their study time, productivity, income and chronotype. Methods: To obtain the results, the assessment of the chronotype in 342 medical students of both sexes was considered. Each participant was submitted to the questionnaire developed by Horne and Ostberg, adapted by Cardinali, Colomberk and Rey. It's composed of 9 questions, providing the general ranking of each individual. Based upon scored, the chronotypes were classified. Results: The sample was composed of 49.12% (168) male and 50.87% (174) female subjects, a similar gender distribution of enrolled students during data collection time. By applying the questionnaire, the prevalent rating among the medical students as moderately morning (29.82%) and intermediate (43.85%) has been relevant. The academic performance assessment in two morning-intermediate groups (8.16) had no significant distance from others considered afternoon active (8.20). Conclusion: The health sciences student, especially Medicine, faces constant adaptation of scheduling, in the attempt of fulfilling the requirements throughout the course, causing chronogram desynchronization effects and forced readaptation to each different school semester.

We evaluated the involvement of the serotonergic system on memory formation and learning processes in healthy adults Wistar rats. Fifty-seven rats of 5 groups had one serotonergic nuclei damaged by an electric current. Electrolytic lesion was carried out using a continuous current of 2mA during two seconds by stereotactic surgery. Animals were submitted to learning and memory tests. Rats presented different responses in the memory tests depending on the serotonergic nucleus involved. Both explicit and implicit memory may be affected after lesion although some groups showed significant difference and others did not. A damage in the serotonergic nucleus was able to cause impairment in the memory of Wistar. The formation of implicit and explicit memory is impaired after injury in some serotonergic nuclei.Keywords: memory, rat, serotonin, learning, neuronal plasticity. Avaliação do sistema serotonérgico na formação de memória e aprendizagem ResumoAvaliar a participação do sistema serotoninérgico em processos de formação de memória e aprendizagem em ratos Wistar adultos saudáveis. Cinquenta e sete ratos de 5 grupos tinham um núcleo serotoninérgico danificado por uma corrente elétrica. A lesão eletrolítica foi realizada utilizando uma corrente contínua de 2 mA durante dois segundos por cirurgia estereotáxica. Os animais foram submetidos a testes de aprendizagem e memória. Os ratos apresentaram respostas diferentes nos testes de memória, dependendo do núcleo serotoninérgica envolvido. A memória explícita e implícita pode ser afetada após a lesão, embora alguns grupos apresentaram diferença significativa e outros não. A lesão no núcleo serotoninérgico foi capaz de causar danos na memória de Wistar. A formação da memória implícita e explícita é prejudicada após a lesão em alguns núcleos serotoninérgicos.Palavras-chaves: memória, rato, serotonina, aprendizagem, plasticidade neuronal.

Objetivo: Verificar os efeitos da interferência de telefone móvel sobre a memória e atenção em universitários e características determinantes da dependência do smartphone. Métodos: Trata-se de estudo observacional e transversal. Participaram da pesquisa 235 acadêmicos de uma universidade pública, de ambos os sexos, idade de 18 a 39 anos que preencheram um formulário sócio demográfico e uma escala de dependência ao smartphone. Os voluntários considerados dependentes foram divididos em três grupos: telefone à vista; telefone somestésico; telefone fora da vista e foram submetidos aos testes de memória e atenção. Resultados: Não foi observado nesse estudo diferenças quanto à memória e atenção nas três condições experimentais. A prevalência da dependência foi 62,55% nos universitários, com predominância maior no sexo feminino. Já a condição de viver “sozinho” foi associada a uma maior dependência. Também foi observado que a dependência é mais frequente em indivíduos que não trabalham. Conclusão: Conclui-se que não existe déficit para realização de atividades que envolvam memória e atenção, se o aparelho celular estiver próximo ou distante do estudante. No entanto, a alta porcentagem de universitários dependentes ao aparelho se torna um problema de saúde pública por causa das consequências à saúde mental, social ou física.

Background: Alzheimer's disease is a progressive and neurodegenerative disorder characterized by deterioration of brain functions. Psychosocial interventions such as music and photographic stimuli may contribute to cognitive and sensory exercise or rehabilitation. Objective: Evaluate musical and photographic stimuli in elderly people with Alzheimer's disease. Methods: It is an uncontrolled clinical trial, before-after type, eleven subjects composing the sample. Participants were submitted to Katz Index, Autobiographical Memory Test, GDS-15, Mini-Mental State Examination. The collection instruments were used on the first and last day of intervention, individually. There were 2 sessions in the week with duration of 50 minutes totaling 20 sessions. Data were analyzed by descriptive and inferential statistics and as variables expressed as mean standard deviation. Results: There was a significant effect of cognitive activity (P < 0.01), it was observed that a small advance (P = 0.05) of the daily life activities. With the analysis of GDS-15, it is verified that they are more effective for the increase of the previous self-estimation of the therapy (P = 0.94).

The dopamine content in cerebral structures has been related to neuronal excitability and several approaches have been used to study this phenomenon during seizure vulnerability period. In the present work, we describe the effects of dopamine depletion after the administration of 6-hidroxidopamine (6-OHDA) into the substantia nigra pars compacta of male rats submitted to the pilocarpine model of epilepsy. Susceptibility to pilocarpine-induced status epilepticus (SE), as well as spontaneous and recurrent seizures (SRSs) frequency during the chronic period of the model were determined. Since the hippocampus is one of main structures in the development of this experimental model of epilepsy, the dopamine levels in this region were also determined after drug administration. In the first experiment, 62% (15/24) of 6-OHDA pre-treated rats and 45% (11/24) of those receiving ascorbic acid as control solution progressed to motor limbic seizures evolving to SE, after the administration of pilocarpine. Severeness of seizures during the model´s the acute period, was significantly higher in epileptic experimental rats (56.52%), than in controls (4.16%). In the second experiment, the frequency of seizures in the model’s chronic phase did not significantly change between groups. Our data show that dopamine may play an important role on seizure severity in the pilo’s model acute period, which seems to be due to dopamine inhibitory action on motor expression of seizure.
