Efficacy and safety of adenosine, rapid ventricular pacing and hypothermia in cerebral aneurysms clipping: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: Cerebral aneurysms in complex anatomical locations and intraoperative rupture can be challenging. Many methods to reduce blood flow can facilitate its exclusion from the circulation. This study evaluated the safety and efficacy of using adenosine, rapid ventricular pacing, and hypothermia in cerebral aneurysm clipping. METHODS: Databases (PubMed, Embase, and Web of Science) were systematically searched for studies documenting the use of adenosine, rapid ventricular pacing, and hypothermia in cerebral aneurysm clipping and were included in this single-arm meta-analysis. The primary outcome was 30-day mortality. Secondary outcomes included neurological outcomes by mRs and GOS, and cardiac outcomes. We evaluated the risk of bias using ROBIN-I, a tool developed by the Cochrane Collaboration. OpenMetaAnalyst version 2.0 was used for statistical analysis and I2 measured data heterogeneity. Heterogeneity was defined as an I2 > 50%. RESULTS: Our systematic search yielded 10,100 results. After the removal of duplicates and exclusion by title and abstract, 64 studies were considered for full review, of which 29 were included. The overall risk of bias was moderate. The pooled proportions of the adenosine analysis for the different outcomes were: For the primary outcome: 11,9%; for perioperative arrhythmia: 0,19%; for postoperative arrhythmia: 0,56%; for myocardial infarction incidence: 0,01%; for follow-up good recovery (mRs 0-2): 88%; and for neurological deficit:14.1%. In the rapid ventricular pacing analysis, incidences were as follows: peri operative arrhythmia: 0,64%; postoperative arrhythmia: 0,3%; myocardial infarction: 0%. In the hypothermia analysis, the pooled proportion of 30-day mortality was 11,6%. The incidence of post-op neurological deficits was 35,4% and good recovery under neurological analysis by GOS was present in 69.2%. CONCLUSION: The use of the three methods is safe and the related complications were very low. Further studies are necessary, especially with comparative analysis, for extended knowledge.

Optimizing radiotherapy strategies for skull base chordoma: a comprehensive meta-analysis and systematic review of treatment modalities and outcomes.

OBJECTIVE: In the treatment of skull base chordoma (SBC) surgery is considered the mainstay approach, and gross-total resection has an established relationship with progression-free survival (PFS) and overall survival (OS). However, the tumor's location often interferes with attempts at complete resection. In this case, surgery for maximal resection followed by high-dose radiotherapy has been demonstrated to be the standard treatment. In this context, various modalities are available, yet no consensus exists on the most effective. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of different radiotherapy modalities for SBC. METHODS: Following PRISMA guidelines, the authors systematically searched for the treatment of SBC with radiation modalities in the PubMed, Cochrane, Web of Science, and EMBASE databases. Outcomes assessed for each modality were as follows: OS, PFS, local control (LC), and complications. The random-effects model was adopted. A single-proportion analysis with 95% CI was used to measure the effects in single-arm analysis. For the comparative analysis, the OR with 95% CI was used to compare outcome treatment effects. Heterogeneity was assessed using I2 statistics, and statistical significance was defined as p < 0.05. RESULTS: A total of 32 studies comprising 3663 patients, with 2322 patients who were treated with radiotherapeutic modalities, were included. Regarding 5-year OS findings in each modality study, the findings were as follows: in photon fractionated radiotherapy, an estimated rate of 77% (69%-84%, 568 patients); in conventional fractionated radiotherapy, 76% (65%-87%, 517 cases); in proton-based + carbon ion-based radiotherapy, 85% (82%-88%, 622 cases); and in a comparative analysis of proton-based and carbon ion-based therapy, there was an OR of 1.2 (95% CI 0.59-2.43, 306 cases). Regarding the 5-year PFS estimate, the rates were as follows: 35% (26%-45%, 95 cases) for photon fractionated therapy; 35% (25%-45%, 85 cases) for stereotactic radiotherapy; 77% (50%-100%, 180 cases) for proton-based and carbon ion-based radiotherapy; and 74% (45%-100%, 102 cases) for proton-based radiotherapy. Regarding LC in periods of 3 and 5 years after proton- and carbon ion-based therapy, the overall estimated rates were 84% (78%-90%, 326 cases) and 75% (65%-85%, 448 cases), respectively. For proton-based radiotherapy and carbon ion-based therapy, the 5-year LC rates were 76% (67%-86%, 259 cases) and 75% (59%-91%, 189 cases), respectively. CONCLUSIONS: The analysis highlights the finding that particle-based modalities like proton beam radiotherapy and carbon ion radiotherapy are the most effective radiation therapies available for the treatment of SBC. Furthermore, it reinforces the idea that surgery followed by radiotherapy constitutes the standard treatment.

Is time really brain in stroke therapy?: A meta-analysis of mechanical thrombectomy up to 155 h post ictus.

BACKGROUND AND OBJECTIVES: Mechanical thrombectomy (MT) has been established as the gold standard of treatment for patients with Acute Ischemic Stroke (AIS) who present up to 6 h after the onset of the stroke. Recently, the DEFUSE-3 and DAWN trials established the safety of starting the MT procedure up to 16 and 24 h after the patient was last seen well, respectively. The purpose of this study is to assess the safety and functional effects of thrombectomy in individuals with AIS detected at a late stage (> 24 h). MATERIALS AND METHODS: PubMed, Web of Science, Embase, and Cochrane databases were thoroughly searched for research on MT in patients in the extremely late time window after AIS. The primary outcomes were symptomatic cerebral hemorrhage, 90-day mortality, Thrombolysis in Cerebral Infarction (TICI) 2b-3, and Modified Rankin Scale (mRS) 0-2. RESULTS: Our study included fifteen studies involving a total of 1,221 patients who presented with AIS and an extended time window. The primary outcome of interest was the favorable functional outcome, mRS 0-2 at 90 days. The pooled proportion for this outcome was 45% (95% confidence interval 34-58%). Other outcomes included the TICI 2b or 3 (successful recanalization), which was reported in 12 studies and had a 79% incidence in the study population (95% CI 68-87%). Complications included: symptomatic intracranial hemorrhage (sICH), which revealed an incidence of 7% in the study population (95% CI 5-10%); and 90-day mortality, which reported a 27% incidence (95% CI 24-31%). In addition, we conducted a comparative analysis between endovascular treatment and standard medical therapy. CONCLUSION: Our meta-analysis provides evidence that supports the need of further randomized and prospective clinical trials to better assess the effectiveness and safety of MT in these patients.

Standard medical therapy with vs. without nebulised magnesium for children with asthma decompensation.

Pediatric asthma is a common condition, and its exacerbations can be associated with significant morbidity and mortality. The role of nebulised magnesium as adjunct therapy for children with asthma exacerbations is still unclear. To compare clinical and functional outcomes for children with asthma exacerbation taking either nebulised magnesium sulfate added to standard medical therapy (SMT) versus SMT alone. PubMed, Embase, and Cochrane Library were systematically searched for randomised clinical trials (RCT) comparing the use of SMT with vs. without nebulised magnesium. The outcomes were respiratory rate, heart rate, % predicted peak expiratory flow rate (PEFR), % predicted forced expiratory volume (FEV1), peripheral O2 saturation, asthma severity scores, and need for intravenous (IV) bronchodilator use. Twelve RCTs and 2484 children were included. Mean age was 5.6 (range 2-17) years old, mean baseline % predicted FEV1 was 69.6%, and 28.66% patients were male. Children treated with magnesium had a significantly higher % predicted PEFR (mean difference [MD] 5.33%; 95% confidence interval [CI] 4.75 to 5.90%; p < 0.01). Respiratory rate was significantly lower in the magnesium group (MD -0.70 respirations per minute; 95% CI -1.24 to -0.15; p < 0.01). Need for IV bronchodilators, % predicted FEV1, heart rate, asthma severity scores, and O2 saturation were not significantly different between groups. CONCLUSION: In children with asthma exacerbation, treatment with nebulised magnesium and SMT was associated with a statistically significant, but small improvement in predicted PEFR and respiratory rate, as compared with SMT alone. WHAT IS KNOWN: • Magnesium sulfate has bronchodilating properties and aids in the treatment of asthma exacerbation when administered intravenously. • There is no significant evidence of benefit of nebulised magnesium as an adjunct therapy to the standard medical treatment for children with asthma exacerbations. WHAT IS NEW: • Our study suggests nebulised magnesium sulfate may have a statistically significant, but small benefit in respiratory rate and peak expiratory flow rate. The addition of nebulised magnesium does not seem to increase adverse events.

Efficacy and Safety of Clazosentan After Aneurysmal Subarachnoid Hemorrhage: An Updated Meta-Analysis.

BACKGROUND AND OBJECTIVES: Clazosentan has been studied to treat cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH).This meta-analysis of randomized controlled trials updates the current knowledge regarding the efficacy and safety of clazosentan compared with placebo after aSAH. METHODS: Databases were systematically searched for randomized controlled trials directly comparing the use of clazosentan and placebo for the treatment of cerebral vasospasm after aSAH. Additional eligibility criteria were the report of any of the outcomes of interest (vasospasm, morbidity, functional outcome, or mortality). The primary outcome was vasospasm-related delayed cerebral ischemia (DCI). The analyses were stratified by clazosentan dosage (low or high dose) and aneurysm treatment modality (clipping or coiling). The Cochrane RoB-2 tool was used for studies quality assessment. RESULTS: Six studies comprising 7 clinical trials were included, involving 2778 patients. Clazosentan decreased the risk of vasospasm-related DCI (risk ratio [RR] 0.56, 95% CI 0.38-0.81) and delayed ischemic neurological deficit (RR 0.63, 95% 0.50-0.80). Angiographic vasospasm (RR 0.54, 95% CI 0.47-0.61) was also decreased. Functional outcomes (favorable Glasgow Outcome Scale, RR 0.99, 95% CI 0.79-1.24) and death (RR 1.03, 95% CI 0.71-1.49) did not change. Meanwhile, adverse events were increased by clazosentan (RR 1.54, 95% CI 1.35-1.76). CONCLUSION: Clazosentan decreased vasospasm-related DCI and angiographic vasospasm but did not improve functional outcomes or mortality. Adverse events were increased by clazosentan.

Efficacy and safety of cavernous sinus medial wall resection in pituitary adenoma surgery: a systematic review and a single-arm meta-analysis.

INTRODUCTION: Pituitary adenomas, benign tumors, can lower quality of life. Pituitary adenomas that invade the medial wall and cavernous sinus (CS) indicate tumor recurrence and partial surgical excision. Despite the cavernous sinus's complexity and risks, new research has improved the surgical procedure and made excision safer. This comprehensive review and single-arm meta-analysis evaluates endocrinological remission and resection rates in pituitary adenomas to determine the benefits and risks of MWCS resection. METHODS: Databases were systematically searched for studies documenting the resection of the medial wall of the cavernous sinus. The primary outcome was endocrinological remission in patients who underwent resection of the MWCS. RESULTS: Eight studies were included in the final analysis. The pooled proportion of endocrinological remission (ER) was 63.3%. The excision of MWCS pooled a gross total resection (GTR) proportion of 72.9%. Finally, ICA injury attained a pooled ratio of 0.5%, indicating minimal morbidity in the procedure. CONCLUSION: The cavernous sinus was ruled out, proving the MWCS excision is safe. Limiting population selection to Knosp 3A or lower enhanced GTR frequencies and lowered recurrence, according to subgroup analyses. This meta-analysis shows that MWCS resection can be a beneficial treatment option for pituitary tumors, when there is no macroscopic medial wall invasion and careful patient selection is done, especially for GH- and ACTH-producing tumors that can cause life-threatening metabolic changes.

Robot-assisted vs. manually guided stereoelectroencephalography for refractory epilepsy: a systematic review and meta-analysis.

Robotic assistance has improved electrode implantation precision in stereoelectroencephalography (SEEG) for refractory epilepsy patients. We sought to assess the relative safety of the robotic-assisted (RA) procedure compared to the traditional hand-guided one. A systematic search on PubMed, Web of Science, Embase, and Cochrane was performed for studies directly comparing robot-assisted vs. manually guided SEEG to treat refractory epilepsy. The primary outcomes included target point error (TPE), entry point error (EPE), time of implantation of each electrode, operative time, postoperative intracranial hemorrhage, infection, and neurologic deficit. We included 427 patients from 11 studies, of whom 232 (54.3%) underwent robot-assisted surgery and 196 (45.7%) underwent manually guided surgery. The primary endpoint, TPE, was not statistically significant (MD 0.04 mm; 95% CI - 0.21, - 0.29; p = 0.76). Nonetheless, EPE was significantly lower in the intervention group (MD - 0.57 mm; 95% CI - 1.08; - 0.06; p = 0.03). Total operative time was significantly lower in the RA group (MD - 23.66 min; 95% CI - 32.01, - 15.31; p < 0.00001), as well as the individual time of implantation of each electrode (MD - 3.35 min; 95% CI - 3.68, - 3.03; p < 0.00001). Postoperative intracranial hemorrhage did not differ between groups: robotic (9/145; 6.2%) vs. manual (8/139; 5.7%) (RR 0.97; 95% CI 0.40-2.34; p = 0.94). There was no statistically relevant difference in infection (p = 0.4) and postoperative neurological deficit (p = 0.47) incidence between the two groups. In this analysis, there is a potential relevance in the RA procedure when comparing the traditional one, since operative time, time of implantation of each electrode, and EPE were significantly lower in the robotic group. More research is needed to corroborate the superiority of this novel technique.

Dimensões do assédio na escola: diálogos sobre gênero com jovens estudantes de ensino médio de São Paulo/Brasil / Dimensiones del acoso en la escuela: diálogos sobre género con jóvenes estudiantes de la enseñanza media de São Paulo/Brasil / Dimensions of harassment at school: dialogs about gender with young high school students in São Paulo/Brazil

Neste artigo, discutimos os usos da categoria "assédio" empregada por jovens estudantes de escolas públicas de Ensino Médio para dar sentido a experiências de violência e discriminação de gênero ocorridas dentro e fora da escola. A análise baseia-se em registros de trabalho de campo produzidos no âmbito de uma pesquisa multicêntrica e de métodos mistos, realizada em nove escolas de São Paulo (SP/BR). O assédio aparece como uma categoria polissêmica que, ao nomear a violência, ajuda no enfrentamento das hierarquias e desigualdades de gênero e geração. Depreendemos que as jovens têm questionado normativas e atitudes que alimentam as desigualdades de gênero nas escolas, além de denunciarem o silenciamento ou inadequação da instituição no enfrentamento do problema, o que possibilita identificar convergências com uma nova sensibilidade em torno da violência contra mulheres que os discursos feministas globalizados fizeram emergir.(AU)

El acoso parece como una categoría polisémica que, al nombrar la violencia, ayuda en el enfrentamiento de las jerarquías y desigualdades de género y generación. Concluimos que las jóvenes han puesto en tela de juicio normativas y actitudes que alimentan las desigualdades de género de las escuelas, además de denunciar el silenciamiento o la inadecuación de la institución en el enfrentamiento del problema, lo que posibilita la identificación de convergencias con una nueva sensibilidad alrededor de la violencia contra mujeres que los discursos feministas globalizados hicieron surgir.(AU)

Abstract In this article, we discuss uses of "harassment" as a category employed by young students from public high schools to make sense of violence and gender discrimination experiences that occur in and out of school. The analysis is based on fieldwork records produced within the scope of a multicenter, mixed-methods research carried out in nine schools located in São Paulo. Harassment appears as a polysemic category that, by naming violence, helps to face gender and generation hierarchies and inequalities. We infer that the young girls have questioned norms and attitudes that feed gender inequalities in schools; in addition, they have denounced the silence or inadequacy of the institution in facing the problem. This enables to identify convergences with a new sensibility regarding violence against women that globalized feminist discourses have brought to the surface.(AU)

Endoscopic endonasal transsphenoidal approach during COVID-19 pandemic in Brazil.

Background: Endoscopic endonasal transsphenoidal approach (EETA) is a well-established technique for sellar tumor resection. However, this route causes aerosol dispersion from the nasal cavity. In the context of the coronavirus (COVID-19) pandemic, new measures were taken aiming at the safety and protection of patients and health-care professionals. Herein, we present a Brazilian experience with EETA during COVID-19 pandemic. Methods: This study was based on the review of medical records and observation in the operating room of the patients undergoing endoscopic surgery in the period from May 2020 to July 2022. All patients were tested by real-time polymerase chain reaction (RT-PCR) COVID-19 before and after surgery. Since September 2021, it has been mandatory to present vaccination cards for adults (over 18 years old). Results: This case series included 28 patients and 35 surgical procedures using the EETA, who presented of nonfunctioning macroadenomas (19 cases - 67.8%), GH-secreting tumor (three cases - 10.8%), ACTH-secreting tumor (three cases - 10.8%), meningiomas (two cases - 7.1%), and Rathke's cleft cyst (one case - 3.5%). There were eight cases of diabetes insipidus (28.5%), five cases of cerebrospinal fluid leak (17.8%), and one case of meningitis (3.5%). Three patients died due to meningitis (one case), carotid occlusion (one case), and COVID-19 complications (one case). Conclusion: A simple protocol was established to perform EETA during the COVID-19 pandemic. The pituitary surgeries were maintained to treat critical cases. To date, the protocol should be continually updated to improve the procedure's safety.

Diversidade e diferença: desafios para a formação dos profissionais de saúde / Diversity and difference: health professional training challenges

Resumo O artigo tem como objetivo discutir a questão da diversidade a partir da sua incorporação na formação dos profissionais de saúde por meio da análise das Diretrizes Curriculares Nacionais (DCN) de dois cursos de graduação na área da saúde no Brasil: medicina e psicologia. Para isso, problematiza a questão da diversidade a partir da contribuição das ciências sociais, ao considerar as múltiplas noções presentes na natureza das diferenças sociais e culturais, rompendo com conceitos essencialistas de diferença. Reflete-se sobre como a diversidade está presente nas diretrizes curriculares desses cursos e, a partir de trabalhos recentes, analisa-se como a diversidade tem sido contemplada na formação, bem como os principais desafios colocados. A interseccionalidade é considerada um referencial teórico político importante para apreender a articulação de múltiplas diferenças e desigualdades que atuam de forma dinâmica, fluida e flexível a partir de contextos históricos particulares, sendo nesse sentido sensível para abordar a questão da diversidade na formação dos profissionais de saúde. Destaca-se a importância de realizar uma análise das diferenças, sugerindo um quadro analítico que articule discursos e práticas, formas de subjetivação e relações sociais.

Abstract This paper aims to discuss the issue of diversity from its incorporation into the training of health professionals through the analysis of the National Curriculum Guidelines (DCN) of two Brazilian undergraduate health courses: medicine and psychology. Thus, it debates the concept of diversity from the contribution of the social sciences, considering the multiple concepts in the nature of social and cultural differences, breaking with essentialist concepts of difference. Reflecting on how diversity appears in the curricular guidelines of these courses, it analyzes from recent studies how this has been considered in training and the main challenges. Intersectionality is an essential political theoretical framework to apprehend the articulation of multiple differences and inequalities acting in a dynamic, fluid, and flexible way from particular historical contexts. Thus, it is sensitive to address the issue of diversity in the training of health professionals. We highlight the importance of studying differences, suggesting an analytical framework that articulates discourses, practice, subjectivation, and social relationships.

Resection arthroplasty for isolated costotransverse joint osteoarthritis: A case report and literature review.

BACKGROUND: Symptomatic isolated costovertebral joint (CVJ) osteoarthritis is rare, and establishing this diagnosis is often difficult. There are few reports in the literature about how to surgically manage these lesions. Our aim was to describe a case of isolated osteoarthritis of the costotransverse joint (CTJ) successfully treated with a resection arthroplasty. CASE DESCRIPTION: A 51-year-old female presented with 3 years of the right paravertebral T 10-level back and radiating pain. No conservative treatment modality effectively resolved this pain (i.e., these included anti-inflammatory medications, physiotherapy, and joint blockages). MRI, CT, and technetium-99m methylene diphosphonate bone scintigraphy demonstrated inflammatory changes involving the right T10 CTJ. Following resection arthroplasty, the patient's symptoms abated. CONCLUSION: Symptomatic osteoarthritis of the right T10 CVJ successfully resolved following costotransversectomy for joint resection arthroplasty.

Spinal dural arteriovenous fistula rupture after Rathke's cleft cyst endoscopic resection: Case report and literature review.

BACKGROUND: Spinal dural arteriovenous fistula (SDAVF) is the most frequent vascular malformation of the spine and accounts for approximately 70% of all vascular spinal malformations. In rare cases, SDAVF rupture and subsequent subarachnoid hemorrhage or intramedullary hematoma may occur. The aim of this article is to present a fatal case of SDAVF rupture after a Rathke's cleft cyst (RCC) endoscopic resection. CASE DESCRIPTION: An 80-year-old female was referred to our hospital with a clinical presentation of bilateral reduction in visual acuity, bitemporal hemianopsia, and sellar magnetic resonance imaging (MRI) highly suggestive of RCC. After the first endonasal endoscopic surgery, the cyst was partially removed and vision improved. No signs of cerebrospinal fluid (CSF) leak were observed. After 1 year, the patient returned because of RCC recurrence and decreased visual acuity. In the second procedure, the lesion was totally resected and CSF leak was observed. A nasoseptal flap was rotated to cover the skull base defect. The patient developed subtle paraparesis followed by paraplegia on the 4th postoperative day. The dorsal spine MRI revealed a T3-T4 intramedullary hematoma. A dorsal laminectomy was performed and a SDAVF was observed. During microsurgery, at the right T3 nerve root level, an arteriovenous shunting point was identified, coagulated, and divided. The intramedullary hematoma was evacuated. The patient developed neurogenic and septic shock and died. CONCLUSION: Venous hypertension, venous wall fragility, and venous thrombosis seem to be the main factors involved in SDAVF rupture. In this particular case, reduction of the extravascular pressure and sudden variation in the pressure gradient caused by sustained CSF leak, also appeared to play an important role in SDAVF rupture. It may represent one more complication related to radical resection of RCC.

Removal of the Retained Ventricular Catheter Using the Endoscopic Monopolar Instrument.

BACKGROUND: Ventriculoperitoneal shunt (VPS) remains the main treatment for hydrocephalus. However, VPS revision surgery is very common. Here, we present a case in which the retained ventricular catheter was removed using the endoscopic monopolar instrument. METHODS: We report a case of a 28-year-old female who presented with VPS obstruction. She had two previous shunt revision surgeries due to shunt obstruction. Eleven years after the last one, she presented an abdominal pseudocyst that indicated a total system removal. During VPS revision surgery, a retained ventricular catheter was observed. The endoscopic monopolar instrument was introduced into the retained catheter under direct view. Coagulations in a back-and-forth movement were applied to release inner catheter adhesions. After these steps, the catheter was removed, and a new one was placed through the same route. RESULTS: The catheter was removed without complications, confirmed by the postoperative cranial computed tomography. The patient remained asymptomatic. CONCLUSION: The described technique was effective and avoided ventricular bleeding. Further studies are necessary to validate this method.
