Evaluation of deep learning algorithms in detecting moyamoya disease: a systematic review and single-arm meta-analysis.

The diagnosis of Moyamoya disease (MMD) relies heavily on imaging, which could benefit from standardized machine learning tools. This study aims to evaluate the diagnostic efficacy of deep learning (DL) algorithms for MMD by analyzing sensitivity, specificity, and the area under the curve (AUC) compared to expert consensus. We conducted a systematic search of PubMed, Embase, and Web of Science for articles published from inception to February 2024. Eligible studies were required to report diagnostic accuracy metrics such as sensitivity, specificity, and AUC, excluding those not in English or using traditional machine learning methods. Seven studies were included, comprising a sample of 4,416 patients, of whom 1,358 had MMD. The pooled sensitivity for common and random effects models was 0.89 (95% CI: 0.85 to 0.92) and 0.92 (95% CI: 0.85 to 0.96), respectively. The pooled specificity was 0.89 (95% CI: 0.86 to 0.91) in the common effects model and 0.91 (95% CI: 0.75 to 0.97) in the random effects model. Two studies reported the AUC alongside their confidence intervals. A meta-analysis synthesizing these findings aggregated a mean AUC of 0.94 (95% CI: 0.92 to 0.96) for common effects and 0.89 (95% CI: 0.76 to 1.02) for random effects models. Deep learning models significantly enhance the diagnosis of MMD by efficiently extracting and identifying complex image patterns with high sensitivity and specificity.

Application of Machine Learning for Classification of Brain Tumors: A Systematic Review and Meta-Analysis.

BACKGROUND: Classifying brain tumors accurately is crucial for treatment and prognosis. Machine learning (ML) shows great promise in improving tumor classification accuracy. This study evaluates ML algorithms for differentiating various brain tumor types. METHODS: A systematic review and meta-analysis were conducted, searching PubMed, Embase, and Web of Science up to March 14, 2023. Studies that only investigated image segmentation accuracy or brain tumor detection instead of classification were excluded. We extracted binary diagnostic accuracy data, constructing contingency tables to derive sensitivity and specificity. RESULTS: Fifty-one studies were included. The pooled area under the curve for glioblastoma versus lymphoma and low-grade versus high-grade gliomas were 0.99 (95% confidence interval [CI]: 0.98-1.00) and 0.89, respectively. The pooled sensitivity and specificity for benign versus malignant tumors were 0.90 (95% CI: 0.85-0.93) and 0.93 (95% CI: 0.90-0.95), respectively. The pooled sensitivity and specificity for low-grade versus high-grade gliomas were 0.99 (95% CI: 0.97-1.00) and 0.94, (95% CI: 0.79-0.99), respectively. Primary versus metastatic tumor identification yields sensitivity and specificity of 0.89, (95% CI: 0.83-0.93) and 0.87 (95% CI: 0.82-0.91), correspondingly. The differentiation of gliomas from pituitary tumors yielded the highest results among primary brain tumor classifications: sensitivity of 0.99 (95% CI: 0.99-1.00) and specificity of 0.99 (95% CI: 0.98-1.00). CONCLUSIONS: ML demonstrated excellent performance in classifying brain tumor images, with near-maximum area under the curves, sensitivity, and specificity.

Replacement of traditional vagus nerve stimulation with cardiac-based device and seizure reduction: A systematic review and meta-analysis.

INTRODUCTION: For patients with drug-resistant epilepsy (DRE) who are not suitable for surgical resection, neuromodulation with vagus nerve stimulation (VNS) is an established approach. However, there is limited evidence of seizure reduction when replacing traditional VNS (tVNS) device with a cardiac-based one (cbVNS). This meta-analysis compares the seizure reduction achieved by replacing tVNS with cbVNS in a population with DRE. METHODS: We systematically searched PubMed, Embase, and Cochrane Central following PRISMA guidelines. The main outcomes were number of patients experiencing a ≥ 50 % and ≥80 % reduction in seizures, as defined by the McHugh scale. Additionally, we assessed the number of patients achieving freedom from seizures. RESULTS: We included 178 patients with DRE from 7 studies who were initially treated with tVNS and subsequently had it replaced by cbVNS. The follow-up for cbVNS ranged from 6 to 37.5 months. There was a statistically significant reduction in seizure frequency with the replacement of tVNS by cbVNS, using a ≥ 50 % (OR 1.79; 95 % CI 1.07 to 2.97; I²=0 %; p = 0.03) and a ≥ 80 % (OR 2.06; 95 % CI 1.17 to 3.62; I²=0 %; p = 0.01) reduction threshold. Nineteen (13 %) participants achieved freedom from seizures after switching to cbVNS. There was no difference in the rate of freedom from seizures between groups (OR 1.85; 95 % CI 0.81 to 4.21; I²=0 %; p = 0.14). CONCLUSION: In patients with DRE undergoing battery replacement, cbVNS might be associated with seizure reduction (≥50 % and ≥80 % threshold) after switching from tVNS. Randomised controlled trials are necessary to validate these findings.

Neuropsychological outcomes in patients with ruptured anterior communicating artery aneurysms treated by clipping versus coiling: a systematic review and meta-analysis.

Ruptured anterior communicating artery (ACoA) aneurysms are frequently associated with neuropsychological deficits. This review aims to compare neuropsychological outcomes between surgical and endovascular approaches to ACoA. We systematically searched PubMed, Embase, and Web of Science for studies comparing the endovascular and surgical approaches to ruptured ACoA aneurysms. Outcomes of interest were the cognitive function, covered by memory, attention, intelligence, executive, and language domains, as well as motor and visual functions. Nine studies, comprising 524 patients were included. Endovascularly-treated patients showed better memory than those treated surgically (Standardized Mean Difference (SMD) = -2; 95% CI: -3.40 to -0.61; p < 0.01). Surgically clipped patients had poorer motor ability than those with coiling embolization (p = 0.01). Executive function (SMD = -0.20; 95% CI: -0.47 to 0.88; p = 0.55), language (SMD = -0.33; 95% CI: -0.95 to 0.30; p = 0.30), visuospatial function (SMD = -1.12; 95% CI: -2.79 to 0.56; p = 0.19), attention (SMD = -0.94; 95% CI: -2.79to 0.91; p = 0.32), intelligence (SMD = -0.25; 95% CI: -0.73 to 0.22; p = 0.30), and self-reported cognitive status (SMD = -0.51; 95% CI: -1.38 to 0.35; p = 0.25) revealed parity between groups. Patients with ACoA treated endovascularly had superior memory and motor abilities. Other cognitive domains, including executive function, language, visuospatial function, attention, intelligence and self-reported cognitive status revealed no statistically significant differences between the two approaches.

Asleep versus awake GPi DBS surgery for Parkinson's disease: A systematic review and meta-analysis.

BACKGROUND: Patients with Parkinson's Disease (PD) who receive either asleep image-guided subthalamic nucleus deep brain stimulation (DBS) or the traditional awake technique have comparable motor outcomes. However, there are fewer studies regarding which technique should be chosen for globus pallidus internus (GPi) DBS. This systematic review and meta-analysis aims to compare the accuracy of lead placement and motor outcomes of asleep versus awake GPi DBS PD population. METHODS: We systematically searched PubMed, Embase, and Cochrane for studies comparing asleep vs. awake GPi DBS lead placement in patients with PD. Outcomes were spatial accuracy of lead placement, measured by radial error between intended and actual location, motor improvement measured using (UPDRS III), and postoperative stimulation parameters. Statistical analysis was performed with Review Manager 5.1.7. and OpenMeta [Analyst]. RESULTS: Three studies met inclusion criteria with a total of 247 patients. Asleep DBS was used to treat 192 (77.7 %) patients. Follow-up ranged from 6 to 48 months. Radial error was not statistically different between groups (MD -0.49 mm; 95 % CI -1.0 to 0.02; I2 = 86 %; p = 0.06), with a tendency for higher target accuracy with the asleep technique. There was no significant difference between groups in change on motor function, as measured by UPDRS III, from pre- to postoperative (MD 8.30 %; 95 % CI -4.78 to 21.37; I2 = 67 %, p = 0.2). There was a significant difference in postoperative stimulation voltage, with the asleep group requiring less voltage than the awake group (MD -0.27 V; 95 % CI -0.46 to - 0.08; I2 = 0 %; p = 0.006). CONCLUSION: Our meta-analysis indicates that asleep image-guided GPi DBS presents a statistical tendency suggesting superior target accuracy when compared with the awake standard technique. Differences in change in motor function were not statistically significant between groups.

Brain tissue oxygen combined with intracranial pressure monitoring versus isolated intracranial pressure monitoring in patients with traumatic brain injury: an updated systematic review and meta-analysis.

Monitoring intracranial pressure (ICP) is pivotal in the management of severe traumatic brain injury (TBI), but secondary brain injuries can arise despite normal ICP levels. Cerebral tissue oxygenation monitoring (PbtO2) may detect neuronal tissue infarction thresholds, enhancing neuroprotection. We performed a systematic review and meta-analysis to evaluate the effects of combined cerebral tissue oxygenation (PbtO2) and ICP compared to isolated ICP monitoring in patients with TBI. PubMed, Embase, Cochrane, and Web of Sciences databases were searched for trials published up to June 2023. A total of 16 studies comprising 37,820 patients were included. ICP monitoring was universal, with additional placement of PbtO2 in 2222 individuals (5.8%). The meta-analysis revealed a reduction in mortality (OR 0.57, 95% CI 0.37-0.89, p = 0.01), a greater likelihood of favorable outcomes (OR 2.28, 95% CI 1.66-3.14, p < 0.01), and a lower chance of poor outcomes (OR 0.51, 95% CI 0.34-0.79, p < 0.01) at 6 months for the PbtO2 plus ICP group. However, these patients experienced a longer length of hospital stay (MD 2.35, 95% CI 0.50-4.20, p = 0.01). No significant difference was found in hospital mortality rates (OR 0.81, 95% CI 0.61-1.08, p = 0.16) or intensive care unit length of stay (MD 2.46, 95% CI - 0.11-5.04, p = 0.06). The integration of PbtO2 to ICP monitoring improved mortality outcomes and functional recovery at 6 months in patients with TBI.

Efficacy and Safety of Intraoperative Radiotherapy for High-Grade Gliomas: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: High-grade gliomas (HGGs) are aggressive tumors of the central nervous system that cause significant morbidity and mortality. Despite advances in surgery and radiation therapy (RT), HGG still has a high incidence of recurrence and treatment failure. Intraoperative radiotherapy (IORT) has emerged as a promising therapeutic approach to achieve local tumor control while sparing normal brain tissue from radiation-induced damage. METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines to evaluate the use of IORT for HGG. Eligible studies were included based on specific criteria, and data were independently extracted. Outcomes of interest included complications, IORT failure, survival rates at 12 and 24 months, and mortality. RESULTS: Sixteen studies comprising 436 patients were included. The overall complication rate after IORT was 17%, with significant heterogeneity observed. The IORT failure rate was 77%, while the survival rates at 12 and 24 months were 74% and 24%, respectively. The mortality rate was 62%. CONCLUSION: This meta-analysis suggests that IORT may be a promising adjuvant treatment for selected patients with HGG. Despite the high rate of complications and treatment failures, the survival outcomes were comparable or even superior to conventional methods. However, the limitations of the study, such as the lack of a control group and small sample sizes, warrant further investigation through prospective randomized controlled trials to better understand the specific patient populations that may benefit most from IORT. However, the limitations of the study, such as the lack of a control group and small sample sizes, warrant further investigation. Notably, the ongoing RP3 trial (NCT02685605) is currently underway, with the aim of providing a more comprehensive understanding of IORT. Moreover, future research should focus on managing complications associated with IORT to improve its safety and efficacy in treating HGG.

Transradial artery access for carotid artery stenting: A pooled analysis.

INTRODUCTION: Carotid artery stenting (CAS) through transradial access (TRA) is emerging as an alternative to carotid endarterectomy. However, the current evidence base is limited, mainly comprising single-center studies. OBJECTIVE: This systematic review and meta-analysis aim to assess the safety and effectiveness of TRA for CAS, providing evidence to support clinical decisions. METHODS: We conducted searches on PUBMED, Cochrane Library, Embase, and Web of Science databases, including studies on TRA for CAS. Studies with fewer than 20 patients, non-primary outcomes, and non-full-text articles were excluded. RESULTS: We analyzed 14 studies involving 1,166 patients who underwent CAS via TRA. Procedural success rate was high in 13 studies, with a 95% rate (95% CI; 92%-98%). Crossover to TFA access was observed in 12 studies at 6% (95% CI: 3%-9%). Transradial access failure was reported in four studies, with a rate of 0% (95% CI: 0%-0%). Cannulation failure resulted in a rate of 4% (95% CI: 2%-7%). Asymptomatic radial artery occlusion (ARAO) occurred at a rate of 2% based on eight studies (95% CI: 0%-5%). Forearm hematoma was reported in 10 studies, with an occurrence of 1% (95% CI: 0%-2%). Cerebral vascular attacks (CAV) within 30 days were assessed in 13 studies, indicating a 2% occurrence (95% CI: 1%-2%). CONCLUSION: The findings suggest that TRA for CAS yields promising outcomes with high success rates and low complication rates. Further research should focus on randomized controlled trials and long-term outcomes to validate and extend findings.

Early ambulation versus prolonged bed rest for incidental durotomies in spine procedures: a systematic review and meta-analysis.

Incidental durotomies are frequent complications of spine surgery associated with cerebrospinal fluid (CSF) leak-related symptoms. Management typically involves prolonged bed rest to reduce CSF pressure at the durotomy site. However, early ambulation may be a safer, effective alternative. PubMed, Web of Science, Embase, Cochrane, and Scopus were systematically searched for studies comparing early ambulation (bed rest ≤ 24 h) with prolonged bed rest (> 24 h) for patients with incidental durotomies in spine surgeries. The outcomes of interest were CSF leak, hypotensive headache, additional surgical repair, pseudomeningocele, and pulmonary complications. Systematic reviews and meta-analysis were performed following the Cochrane Handbook for Systematic Reviews of Interventions. We included a total of 704 patients from 6 studies. There was a significant reduction in the incidence of pulmonary complications (RR 0.23; 95% CI 0.08-0.67; p = 0.007) in the early mobilization group. The incidence of CSF leak (RR 1.34; 95% CI 0.83-2.14; p = 0.23), hypotensive headache (RR 0.72; 95% CI 0.27-1.90; p = 0.50), additional repair surgery (RR 1.29; 95% CI 0.76-2.2; p = 0.35), and pseudomeningocele (RR 1.29; 95% CI 0.20-8.48; p = 0.79) did not differ significantly. In patients with incidental durotomy following spinal surgery, early mobilization was associated with a lower incidence of pulmonary complications as compared with prolonged bed rest. There was no significant difference between groups in terms of CSF leak, need for additional repair, pseudomeningocele, and hypotensive headache.

Safety of withholding perioperative steroids for patients with pituitary resection with an intact hypothalamus-pituitary-adrenal axis: A meta-analysis of randomized clinical trials.

INTRODUCTION: Several observational studies have evaluated the effects of pre-operative steroids (STER) for transsphenoidal pituitary removal in patients with an intact hypothalamus-pituitary-adrenal axis. However, a consensus built upon randomized studies has not been previously performed. PURPOSE: To comprehensively evaluate the clinical effects of patients receiving STER when compared to those not receiving steroids (NOSTER) in transsphenoidal pituitary resection, a meta-analysis of randomized clinical trials (RCT) was conducted. METHODS: A systematic review of the literature of RCTs comparing STER and NOSTER was performed in accordance with the PRISMA guidelines. Databases, including PUBMED, Cochrane Library, Web of Science, and Embase were queried. The primary outcomes were adrenal insufficiency (AI) and diabetes insipidus (DI) post-operatively. RESULTS: A total of 4 final studies were included, in which 530 total patients were analyzed. The meta-analysis suggested that there was no significant difference between STER and NOSTER groups post-operatively related to transient AI (RR= 0.83, 95% CI [0.51-1.35], p = 0.45; I² = 52%), permanent AI (RR= 0.97, 95% CI [0.41-2.31], p = 0.95; I² = 0%), and permanent DI (RR= 0.62, 95% CI [0.16-2.33], p = 0.48; I² = 0%). Nevertheless, STER group had significantly lower rates of transient DI (RR= 0.60, 95% CI [0.38-0.95], p = 0.03; I² = 5%), and post-op hyponatremia (RR = 0.49, 95% CI [0.28-0.87], p = 0.02; I² = 0%). CONCLUSION: This study demonstrates evidence from RCTs that patients receiving pre-operative STER are both safe and effective pre-operatively for resection of pituitary adenomas with an intact hypothalamus-pituitary-adrenal axis.

Machine Learning Algorithms to Predict Delayed Cerebral Ischemia After Subarachnoid Hemorrhage: A Systematic Review and Meta-analysis.

Delayed cerebral ischemia (DCI) is a common and severe complication after subarachnoid hemorrhage (SAH). Logistic regression (LR) is the primary method to predict DCI, but it has low accuracy. This study assessed whether other machine learning (ML) models can predict DCI after SAH more accurately than conventional LR. PubMed, Embase, and Web of Science were systematically searched for studies directly comparing LR and other ML algorithms to forecast DCI in patients with SAH. Our main outcome was the accuracy measurement, represented by sensitivity, specificity, and area under the receiver operating characteristic. In the six studies included, comprising 1828 patients, about 28% (519) developed DCI. For LR models, the pooled sensitivity was 0.71 (95% confidence interval [CI] 0.57-0.84; p < 0.01) and the pooled specificity was 0.63 (95% CI 0.42-0.85; p < 0.01). For ML models, the pooled sensitivity was 0.74 (95% CI 0.61-0.86; p < 0.01) and the pooled specificity was 0.78 (95% CI 0.71-0.86; p = 0.02). Our results suggest that ML algorithms performed better than conventional LR at predicting DCI.Trial Registration: PROSPERO (International Prospective Register of Systematic Reviews) CRD42023441586; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=441586.

Transradial versus transfemoral access in carotid artery stenting: A meta-analysis.

BACKGROUND: The carotid artery stenting (CAS) has two common access sites: transradial access (TRA) and transfemoral access (TFA). However, there's no definitive answer to which one is superior. OBJECTIVE: Compare TRA and TFA for the CAS. METHODS: A systematic review of the literature of studies reporting both TRA and TFA results was conducted following the PRISMA guidelines. PubMed, Cochrane Library, Web of Science and Embase were queried. RESULTS: The meta-analysis examined nine studies comprising 7513 patients who underwent CAS. Of these, 6750 patients had TFA (90%), while 763 had TRA (10%). There was no significant difference in procedure success rates between TRA and TFA, with a risk ratio (RR) of 0.99 (6/9; 95% CI 0.98 to 1.00; I² = 9%, fixed effects). However, cross-over to TFA was more frequent in TRA (odds ratio (OR) 10.37 (6/9; 95% CI 5.18 to 20.77; I² = 17%, fixed effects)). There were no significant differences in terms of major access complications (RR = 0.88 (7/9; 95% CI: 0.29 to 2.63; I² = 0, fixed effects)), total access complications (RR = 1.10 (6/9; 95% CI: 0.56 to 2.15; I² = 7%, fixed effects)), and mean difference in length of stay (Mean difference of -0.08 (3/9; 95% CI -0.18 to 0.02; I² = 0%, fixed effects)). CONCLUSION: There were no significant differences between TFA and TRA in terms of procedure success rates, time, complications, and length of stay, although cross-over to TFA was more common in TRA cases.

Enfermagem e higienização no gerenciamento dos resíduos sólidos de saúde / Nursing and hygienization in the management of solid health waste / Enfermería e higienización en la gestión de residuos sólidos sanitarios

Objetivo: analisar o conhecimento dos profissionais da equipe de Enfermagem e de higienização sobre o manejo dos resíduos sólidos dos serviços de saúde. Método: trata-se de um estudo quantitativo, descritivo, exploratório. Utilizaram-se para a coleta de dados dois questionários, um para a equipe de Enfermagem com 53 integrantes e outro para a equipe de limpeza com 21 integrantes, abordando questões pertinentes a cada categoria profissional. Calcularam-se as frequências relativas e absolutas das respostas para fins de mensuração e comparação. Resultados: observou-se, um nível de acertos alto de ambos os grupos entrevistados, que pode estar associado ao fato de a instituição manter, no seu Plano de Gerenciamento de Resíduos de Saúde, um programa de educação continuada, independentemente do tipo de vínculo empregatício dos trabalhadores. Conclusão: conclui-se que o conhecimento dos profissionais envolvidos sobre a prática correta do gerenciamento de resíduos de saúde demonstrou-se satisfatório e aqui destacamse os profissionais de limpeza, por vezes, negligenciados. Pontua-se que não se pode negar o impacto desse trabalho conjunto nos custos da instituição, na saúde dos trabalhadores e na preservação do meio ambiente.(AU)

Objective: to analyze the knowledge of the Nursing and Cleaning team professionals on the management of solid waste from health services. Method: It is a quantitative, descriptive, exploratory study. Two questionnaires were used for data collection, one for the 53-member nursing team and the other for the 21-member cleaning team, addressing issues relevant to each professional category. The relative and absolute frequencies of the answers were calculated for measurement and comparison purposes. Results: It was observed a high level of success of both groups interviewed, which may be associated to the fact that the institution maintains, in its Health Waste Management Plan, a program of continuous education, regardless of the type of employment relationship of the workers. Conclusion: The conclusion is that the knowledge of the professionals involved about the correct practice of health waste management has proved to be satisfactory and here cleaning professionals are sometimes neglected. It is pointed out that one cannot deny the impact of this joint work on the institution's costs, on the workers' health and on the environment's preservation.(AU)

Objetivo: analizar el conocimiento de los profesionales del equipo de Enfermería e higienización sobre el manejo de residuos sólidos de los servicios de salud. Método: se trata de un estudio cuantitativo, descriptivo, exploratorio. Para la recolección de datos se utilizaron dos cuestionarios, uno para el equipo de Enfermería con 53 integrantes y otro para el equipo de limpieza con 21 integrantes, abordando temas relevantes para cada categoría profesional. Se calcularon las frecuencias relativas y absolutas de las respuestas con fines de medición y comparación. Resultados: hubo un alto nivel de aciertos de ambos grupos entrevistados, lo que puede estar asociado a que la institución mantiene, en su Plan de Manejo de Residuos Sanitarios, un programa de educación continua, independientemente del tipo de relación laboral de los trabajadores. Conclusión: se concluye que el conocimiento de los profesionales involucrados sobre la correcta práctica de la gestión de residuos sanitarios resultó ser satisfactorio y aquí destacan los profesionales de la limpieza, en ocasiones desatendidos. Se señala que no se puede negar el impacto de este trabajo conjunto sobre los costos de la institución, la salud de los trabajadores y la preservación del medio ambiente.(AU)

Spatial diffusion of Zika fever epidemics in the Municipality of Salvador-Bahia, Brazil, in 2015-2016: does Zika fever have the same spread pattern as Dengue and Chikungunya fever epidemics?

INTRODUCTION: The recent emergence and rapid spread of Zika and Chikungunya fevers in Brazil, occurring simultaneously to a Dengue fever epidemic, together represent major challenges to public health authorities. This study aimed to identify and compare the 2015-2016 spatial diffusion pattern of Zika, Chikungunya, and Dengue epidemics in Salvador-Bahia. METHODS: We used two study designs comprising a cross-sectional-to-point pattern and an ecological analysis of lattice data. Residential addresses involving notified cases were geocoded. We used four spatial diffusion analysis techniques: (i) visual inspection of the sequential kernel and choropleth map, (ii) spatial correlogram analysis, (iii) spatial local autocorrelation (LISA) changes analysis and, (iv) nearest neighbor index (NNI) modeling. RESULTS: Kernel and choropleth maps indicated that arboviruses spread to neighboring areas near the first reported cases and occupied these new areas, suggesting a diffusion expansion pattern. A greater case density occurred in central and western areas. In 2015 and 2016, the NNI best-fit model had an S-curve compatible with an expansion pattern for Zika (R2 = 0.94; 0.95), Chikungunya (R2 = 0.99; 0.98) and Dengue (R2 = 0.93; 0.99) epidemics, respectively. Spatial correlograms indicated a decline in spatial lag autocorrelations for the three diseases (expansion pattern). Significant LISA changes suggested different diffusion patterns, although a small number of changes were detected. CONCLUSIONS: These findings indicate diffusion expansion, a unique spatial diffusion pattern of Zika, Chikungunya, and Dengue epidemics in Salvador-Bahia, namely. Knowing how and where arboviruses spread in Salvador-Bahia can help improve subsequent specific epidemic control interventions.

Renal dysfunction in Leishmaniasis and Chagas disease coinfection: a case report.

Visceral leishmaniasis (VL) is an endemic parasitic disease frequently found in Northeast Brazil and may cause acute kidney injury (AKI) and glomerulonephritis. After appropriate treatment, renal function recovery may occur. We describe the rare case of a patient with VL, who developed severe AKI requiring dialysis and was subsequently diagnosed with Chagas disease coinfection. After specific treatment for VL, there was partial recovery of the renal function, followed by the onset of Chagas disease cardiomyopathy.

Utilização dos indicadores de qualidade da assistência de enfermagem: opinião dos enfermeiros / Use of nursing quality assurance indicators: nurses 'opinion

Objetivo: conhecer a opinião dos enfermeiros sobre a utilização dos indicadores. Método: estudo quantitativo, transversal, descritivo-exploratório, tipo survey, desenvolvido em Hospital Universitário. Os dados foram produzidos a partir de questionário, com 22 questões, aplicado a uma amostra de 60enfermeiros. Para a análise dos dados, foi utilizada a estatística descritiva e apresentações de medidas de frequência relativa, frequência absoluta, média e mediana, a partir de tabelas. Resultados: mostraram que os enfermeiros entendem a importância do uso dos indicadores e os preenchem diariamente. Porém, ainda não há discussão dos resultados com a equipe de Enfermagem, tampouco treinamentos anuais sobre indicadores, e a notificação de eventos adversos ainda é vista com temor, havendo subnotificações dos eventos. Conclusão: há a necessidade de promover a integração dos profissionais com os resultados obtidos e desenvolver treinamentos periódicos. Ainda existe uma cultura negativa sobre a notificação de eventos adversos a ser desmistificada.
