RESUMO
Abstract Objective Complex regional pain syndrome (CRPS) requires further understanding. Thus, the present study aimed to analyze if pre- and intraoperative factors may be related to the development of CRPS in the postoperative period. Methods We reviewed 1,183 medical records of patients undergoing forearm and hand surgeries from 2015 to 2021. The data of interest, that is, diagnosis, incisions, synthesis material, and anesthesia, were collected, tabulated, and statistically analyzed, with subsequent calculation of the odds ratios. Results Most patients were female, aged between 30 and 59 years, and sought the service electively (67% of the cases). The diagnoses included soft tissue trauma (43%), bone trauma (31.6%), and compressive syndromes (25.5%). During this period, 45 (3.8%) subjects developed CRPS. The statistical analysis showed that the chance of developing CRPS is twice as high in patients with compressive syndrome, especially carpal tunnel syndrome (CTS), which represented most surgeries performed in our service (24%). Two or more incisions occurred in 7.6% of the cases, which tripled the chance of developing postoperative CRPS. Gender, age, use pf synthetic material, type of anesthesia type did not statistically increase the risk of developing postoperative CRPS. Conclusion In short, the incidence of CRPS is low; however, it is critical to know and recognize the risk factors for prevention and active screening in the postoperative period.
Resumo Objetivo A síndrome da dor regional complexa (SDRC) precisa ser mais bem compreendida. Assim, este estudo objetiva analisar se fatores pré e intraoperatórios poderiam estar relacionados ao desenvolvimento de SDRC no pós-operatório. Métodos Foram revisados 1.183 prontuários de pacientes submetidos a cirurgias no antebraço e na mão entre 2015 e 2021. Os dados de interesse, como diagnóstico, incisões, material de síntese e anestesia realizada, foram coletados, tabulados e submetidos a testes estatísticos com posterior cálculo da razão de chances. Resultados A maioria dos pacientes era do gênero feminino, com idade entre 30 e 59 anos, que buscaram o serviço de forma eletiva (67% dos casos). Os diagnósticos agrupados de forma geral foram: traumas de partes moles (43%), traumas ósseos (31,6%) e síndromes compressivas (25,5%). Durante esse período, 45 pacientes (3,8%) evoluíram com SDRC. A análise estatística mostrou que a chance de desenvolver SDRC é duas vezes maior em pacientes com síndrome compressiva, especialmente a síndrome do túnel do carpo (STC), que representou a maioria dos cirurgias realizadas em nosso serviço (24%). Em 7,6% dos casos, foram realizadas duas ou mais incisões, o que triplicou a possibilidade de SDRC pósoperatória. Gênero, idade, uso de material de síntese, ou tipo de anestesia não aumentaram estatisticamente o risco de SDRC no pós-operatório. Conclusão Em suma, a incidência de SDRC é baixa, mas é importante conhecer e reconhecer os fatores de risco para a prevenção e a busca ativa no pós-operatório.

RESUMO
Scalable solutions to treat depression in older adults in low-resourced settings are urgently needed. The PRODIGITAL-D pragmatic, single-blind, two-arm, individually randomized controlled trial assessed the effectiveness of a mobile messaging psychosocial intervention in improving depressive symptomatology among older adults in socioeconomically deprived areas of Guarulhos, Brazil. Older adults (aged 60+ years) registered with 24 primary care clinics and identified with depressive symptomatology (9-item Patient Health Questionnaire (PHQ-9) scores ≥ 10) received the 6-week Viva Vida intervention based on psychoeducation and behavioral activation (n = 298) or a single message (n = 305). No health professional support was offered. The primary outcome was improvement from depressive symptomatology (PHQ-9 < 10) at 3 months. Of the 603 participants enrolled (mean age = 65.1 years; 451 (74.8%) women), 527 (87.4%) completed the follow-up assessment. In the intervention arm, 109 of 257 (42.4%) participants had an improved depressive symptomatology, compared with 87 of 270 (32.2%) participants in the control arm (adjusted odds ratio = 1.57; 95% confidence interval = 1.07-2.29; P = 0.019). No severe adverse events related to trial participation were observed. These results demonstrate the usefulness of a digital messaging psychosocial intervention in the short-term improvement from depressive symptomatology that can potentially be integrated into primary care programs for treating older adults with depression.

Among plant-parasitic nematodes, root-knot nematodes (RKN), Meloidogyne spp., are the most important parasite infecting economically important crops globally and causing severe losses in crop production. The use of efficient nematode control methods against these parasites depends upon their correct detection in roots and soil samples. Currently, the use of integrated identification methods, including biochemical, molecular, and morphological-based characters, is preferred. But the techniques using morphology and phylogenetic analysis are time-consuming and not suitable for routine analysis. They have only been used for studies of cryptic species, which were identified using integrative taxonomy. Here we describe the enzymatic and molecular-based methods that have successfully been used in Brazil for more than 25 years in the Nematology Lab at Embrapa Genetic Resources and Biotechnology for routine analysis. This technique is a combination of isozyme esterase profiling and molecular markers, with the aim of having a rapid and correct diagnosis of Meloidogyne spp. populations from field and greenhouse.

Dengue virus (DENV) is a prominent arbovirus with global spread, causing approximately 390 million infections each year. In Brazil, yearly epidemics follow a well-documented pattern of serotype replacement every three to four years on average. Araraquara, located in the state of São Paulo, has faced significant impacts from DENV epidemics since the emergence of DENV-1 in 2010. The municipality then transitioned from low to moderate endemicity in less than 10 years. Yet, there remains an insufficient understanding of virus circulation dynamics, particularly concerning DENV-1, in the region, as well as the genetic characteristics of the virus. To address this, we sequenced 37 complete or partial DENV-1 genomes sampled from 2015 to 2022 in Araraquara. Then, using also Brazilian and worldwide DENV-1 sequences we reconstructed the evolutionary history of DENV-1 in Araraquara and estimated the time to the most recent common ancestor (tMRCA) for serotype 1, for genotype V and its main lineages. Within the last ten years, there have been at least three introductions of genotype V in Araraquara, distributed in two main lineages (L Ia and L Ib, and L II). The tMRCA for the first sampled lineage (2015/2016 epidemics) was approximately 15 years ago (in 2008). Crucially, our analysis challenges existing assumptions regarding the emergence time of the DENV-1 genotypes, suggesting that genotype V might have diverged more recently than previously described. The presence of the two lineages of genotype V in the municipality might have contributed to the extended persistence of DENV-1 in the region.

Introduction: Postoperative urinary retention may predispose to permanent bladder damage. Risk factors include type of anesthesia, type of surgery, and use of anticholinergics, analgesics, and opioids. Once the lesion is established, complementary urodynamic tests are essential for etiological diagnosis and treatment. The objective of this study is to report a case of a patient with urinary retention in the postoperative period of lipoabdominoplasty. Case Report: 27-year-old female patient, without comorbidities or use of continuous medication. She underwent lipoabdominoplasty and evolved postoperatively with urinary retention and bladder distention, diagnosed as detrusor contractility and sensitivity deficit in the urodynamic study. She was maintained in outpatient follow-up with the surgical team and Urology, with a progressive reduction in urinary catheter use and complete removal in eight months of follow-up. Discussion: The objective of aesthetic plastic surgery is to improve the physical appearance of the body. It is subject to complications like other surgical procedures, and pain seems to be the most frequent. Urinary retention may be secondary to the use of opioids, and its diagnosis in the postoperative period of lipoabdominoplasty still has some obstacles. Plication of the rectus muscle diastasis, liposuction, and the use of a compressive abdominal belt make it difficult to identify a possible bladder distention. An episode of bladder overdistention can result in significant morbidity. Conclusion: The present report demonstrated the good evolution of a patient who developed urinary retention in the postoperative period of lipoabdominoplasty. The main diagnostic hypothesis was that it was secondary to the use of opioids.
Introdução: A retenção urinária pós-operatória pode predispor a danos permanentes à bexiga. Os fatores de risco incluem tipo de anestesia, tipo de cirurgia e uso anticolinérgicos, analgésicos e opioides. Uma vez que a lesão está estabelecida, os exames complementares urodinâmicos são fundamentais para diagnóstico etiológico e tratamento. O objetivo deste trabalho é relatar caso de paciente com quadro de retenção urinária no pós-operatório de lipoabdominoplastia. Relato de Caso: Paciente de 27 anos, sexo feminino, sem comorbidades ou uso de medicamentos contínuos. Foi submetida a lipoabdominoplastia, e evoluiu no pós-operatório com quadro de retenção urinária e bexigoma, diagnosticada como acontratilidade detrusora e déficit de sensibilidade no estudo urodinâmico. Manteve acompanhamento ambulatorial com a equipe cirúrgica e a Urologia, com redução progressiva do uso do cateter vesical e retirada completa em oito meses de seguimento. Discussão: O objetivo da cirurgia plástica estética é melhorar o aspecto físico do corpo. Como os demais procedimentos cirúrgicos, está sujeita a complicações e a dor parece ser a mais frequente. A retenção urinária pode ser secundária ao uso de opioides e seu diagnóstico no pós-operatório da lipoabdominoplastia ainda possui alguns obstáculos. A plicatura da diástase do músculo reto, a lipoaspiração e o uso de cinta abdominal compressiva dificultam a identificação do possível bexigoma. Um episódio de hiperdistensão da bexiga pode resultar em morbidade significativa. Conclusão: O presente relato demonstrou boa evolução de paciente que desenvolveu retenção urinária no pós-operatório de lipoabdominoplastia. A principal hipótese diagnóstica foi de ser secundária ao uso de opioide.
RESUMO
Objective: Torque Teno virus (TTV) is a recently discovered virus with high prevalence worldwide, that has been associated with vascular diseases. The aim of this study is to investigate the prevalence of TTV molecular DNA in the intracranial aneurysm (IA) artery walls. Method: Samples of IA walls were collected after microsurgical clipping from 35 patients with IA (22 ruptured/13 unruptured cases). The samples were submitted to molecular DNA extraction using the EasyMag automatized extractor and performed with Qiagen DNA extraction Minikit 250. The samples underwent PCR examination with primers for ß-globin as internal control using the Nanodrop ® 2000 spectrophotometer. A quantitative (real-time) PCR with TTV-specific primers was performed. Clinical and radiological data of patients included was collected. Results: TTV was detected in 15 (42.85%) cases, being 10 (45.4%) ruptured and 5 (38.4%) unruptured (p = 0.732) lesions. Multiple IAs accounted for 14 (40%) cases. Five cases (17.2%) had TTV+ and multiple aneurysms (p = 0.73). Association between presence of virus and aneurysm rupture was not statistically significant (p = 0.96). Conclusion: This study demonstrated a relatively high prevalence of viral DNA in the walls of IAs. This is the first study to identify the presence of TTV DNA in IA's samples, which was found more often in ruptured lesions. This is an exploratory study, therefore, larger studies are required to clarify the relationships between inflammation, viral infection, IA formation and rupture.
RESUMO
This study aimed to investigate the relationship between sociodemographic characteristics, depressive symptomatology, mobile phone ownership, and different uses of WhatsApp among older adults enrolled in primary care clinics in Guarulhos, São Paulo State, Brazil. This is a secondary data analysis, using data collected in the screening of participants to be included in the PROACTIVE cluster randomized trial. Individuals aged ≥ 60 years, registered in primary care clinics in Guarulhos, were assessed for sociodemographic characteristics, depressive symptoms according to the PHQ-9, mobile phone ownership, and use of WhatsApp. We performed multiple logistic regression models to investigate characteristics of the potential users of digital interventions. Of 3,356 older adults screened for depression, 45.7% said they use WhatsApp to receive/send messages. In the subsample that presented depressive symptomatology (n = 1,020), 41.9% stated using WhatsApp. Younger older adults and those with better socioeconomic status used more WhatsApp and were more likely to own a mobile phone. Participants with higher levels of symptoms of depression were less likely to use WhatsApp. Gender, age, schooling level, income, and depressive symptomatology are variables associated with the possession of a cell phone and with the use of WhatsApp by the older adults of the sample. These findings can help to implement digital health programs better suited to disadvantaged populations in Brazil and other low- and middle-income countries through mental telehealth interventions using WhatsApp and mobile health services to the older people.

INTRODUCTION: The brain is the most complex organ in the human body, with a high and constant demand for inputs. Adequate nutrition is essential for the complete functioning of the brain, not only due to the energy supply, mainly from carbohydrates, but also due to the adequate supply of other macronutrients and micronutrients for the synthesis of neurotransmitters and protein components. Vitamins, minerals, and other components of the diet also constitute the so-called "neuro-nutrients". OBJECTIVE: It was to develop a systematic review to highlight key neuro-nutrients and clinical studies that direct strategies for adequate nutritional status. METHODS: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from October 2021 to February 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. RESULTS: A total of 234 articles were found and 167 articles were evaluated in full, and 118 were included and evaluated in the present study. According to the GRADE instrument, most studies (>50%) followed a controlled clinical study model and had a good methodological design. The overall assessment resulted in 54 studies with a high risk of bias to the small sample size. The most important macronutrients in neuro-nutrition are phosphatidylserine and tryptophan. Micronutrients are methyl folate, vitamins B6 and B12, magnesium, arginine, choline, and niacin. CONCLUSION: The areas of neurology and psychiatry have shown great advances regarding the deepening of knowledge in prophylaxis and pathophysiology, as well as in the treatment of established diseases. The recognition of the role of nutrition as an adjunct to these processes is currently growing. The search in scientific bases for neuro nutrients reveals a great growth of publications related to this theme. In the present text, some of these nutrients were explored to verify the current state of knowledge.

BACKGROUND: The VASOGRADE is a simple aneurysmal subarachnoid hemorrhage (aSAH) grading scale that combines the modified Fisher scale (mFisher) and the World Federation of Neurological Societies (WFNS) grading system, allowing the stratification of delayed cerebral ischemia (DCI) risk. However, the VASOGRADE accuracy in predicting functional outcomes is still to be determined. METHODS: We retrospectively evaluated a multiethnic cohort of consecutive patients with aSAH admitted to a high-volume center in Brazil from January 2016 to January 2019. Patients were classified according to the severity of the clinical presentation (WFNS), the amount of blood in the initial head computerized tomography (mFisher) scan, and the VASOGRADE (green, yellow, red). The primary outcome was to detect DCI-related cerebral infarction, and the secondary outcome was the functional outcome at hospital discharge according to the modified Rankin scale (mRs). Univariate and multivariate logistic regression models were employed. RESULTS: A total of 212 patients (71.7% female, mean age 52.7 ± 12.8) were included. Sixty-nine patients were classified as VASOGRADE-Green (32.5%), 98 patients as VASOGRADE-Yellow (46.9%), and 45 patients as VASOGRADE-Red (20.6%). DCI-related infarction was present in 39 patients (18.9%). The proportions of patients in the VASOGRADE-Green, VASOGRADE-Yellow, and VASOGRADE-Red categories with DCI-related infarction were 7.7, 61.5, and 30.8%, respectively. After a multivariable analysis including age, sex, aneurysm location, and the VASOGRADE classification as variables, both VASOGRADE-Yellow and VASOGRADE-Red were independently associated with DCI-related infarction (odds ratio [OR] 7.69, 95% confidence interval [CI] 2.13-27.8, and OR 8.07, 95% CI 2.03-32.11, respectively) and unfavorable outcome (OR 4.16, 95% CI 1.33-13.03, and OR 25.57, 95% CI 4.45-147.1, respectively). The VASOGRADE discrimination performance for DCI-related infarction (area under the receiver operating characteristic curve) was 0.67 ± 0.04 (95% CI 0.58-0.75; p = 0.001). VASOGRADE-Red had 97.5% specificity for predicting an unfavorable mRs score at discharge (95% CI 92.8-99.5%). Conversely, VASOGRADE-Green had an excellent specificity for predicting favorable outcome at discharge (mRs score 0-2, 95% CI 82.6-95.5%). CONCLUSIONS: In conclusion, in a multiethnic cohort of patients with aSAH, VASOGRADE-Green predicted the absence of DCI and good clinical outcome at discharge with very high specificity, and patients in this category might be selected for early intensive care unit (ICU) discharge, minimizing costs and medical complications associated with prolonged hospital stay. On the other hand, patients categorized as VASOGRADE-Yellow and VASOGRADE-Red were at the highest risk for DCI. They should, therefore, be selected as a priority for care in high-volume aSAH centers, being aggressively monitored for DCI at the ICU. Such stratification methods are crucial, especially in countries with low financial resources and high health care services demand.
