RESUMO

BACKGROUND: Glioblastoma (GBM) is the most common devastating primary brain cancer in adults. In our clinical practice, median overall survival (mOS) of GBM patients seems increasing over time. METHODS: To address this observation, we have retrospectively analyzed the prognosis of 722 newly diagnosed GBM patients, aged below 70, in good clinical conditions (i.e. Karnofsky Performance Status -KPS- above 70%) and treated in our department according to the standard of care (SOC) between 2005 and 2018. Patients were divided into two groups according to the year of diagnosis (group 1: from 2005 to 2012; group 2: from 2013 to 2018). RESULTS: Characteristics of patients and tumors of both groups were very similar regarding confounding factors (age, KPS, MGMT promoter methylation status and treatments). Follow-up time was fixed at 24 months to ensure comparable survival times between both groups. Group 1 patients had a mOS of 19 months ([17.3-21.3]) while mOS of group 2 patients was not reached. The recent period of diagnosis was significantly associated with a longer mOS in univariate analysis (HR=0.64, 95% CI [0.51 - 0.81]), p < 0.001). Multivariate Cox analysis showed that the period of diagnosis remained significantly prognostic after adjustment on confounding factors (adjusted Hazard Ratio (aHR) 0.49, 95% CI [0.36-0.67], p < 0.001). CONCLUSION: This increase of mOS over time in newly diagnosed GBM patients could be explained by better management of potentially associated non-neurological diseases, optimization of validated SOC, better management of treatments side effects, supportive care and participation in clinical trials.

RESUMO

OBJECTIVES: To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway. MATERIALS AND METHODS: All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports. The main outcome was the rate of completion of the tests and consultations planned during this evaluation. Secondary outcomes included the findings from the one-day evaluation and changes in the urological surgical strategy at different time points within one year. RESULTS: One hundred and thirty-one patients benefited from this one-day standardized evaluation. The overall completeness rate of the data collected was 77.5%, increasing from 62.3% in 2017 to 89.3% in 2021. The urological surgical plan was modified for 19.1% of patients following this preoperative evaluation. The indication was then confirmed for 114 patients (87.0%) by the multidisciplinary meeting and was carried out unchanged during the following year for 89 patients (67.9%). An associated colostomy procedure was proposed for 18.3% of patients and was finally performed in 11.5%. CONCLUSION: A standardized multidisciplinary preoperative one-day evaluation before performing reconstructive or diversion surgery for the treatment of neurogenic LUT dysfunction seems feasible and makes it possible to optimize the surgical plan and adapt the course of care.

RESUMO

Glioblastoma is the most common primary brain malignancy in adults. Treatment of glioblastoma patients is based on neurosurgery, radiation therapy and chemotherapy. Despite this multimodal therapeutic regimen, the prognosis of glioblastoma patients is poor. Indeed, glioblastoma is very resistant to treatments due to multiple molecular and cellular mechanisms including the existence of the blood-brain barrier (BBB). The BBB consists of multiple layers surrounding brain vessels and limits drug penetration within the brain. Therefore, overcoming the BBB is a strategy to increase bioavailability and efficacy of therapeutic agents against glioblastoma cells. The development of two approaches is ongoing: i) enhancing the delivery of drugs to the brain and ii) improving the penetration of drugs into the brain. One way to enhance drug delivery to the brain is through high-dose intravenous chemotherapy, with or without bone marrow transplantation, or via intra-arterial chemotherapy, with or without disrupting the BBB through osmotic means. Conversely, improving drug penetration within the brain can be achieved through modifying either the drug itself or the BBB. Promising results in terms of safety and signals of efficacy were obtained with these approaches in early phase clinical trials. More advanced comparative clinical trials are needed to investigate the clinical benefit for glioblastoma patients.

RESUMO

BACKGROUND AND PURPOSE: Intracranial aneurysms are frequent in patients with sickle cell anemia, while subarachnoid hemorrhage is a major cause of death and disability in young adult patients. Several characteristics, such as younger age and smaller size at rupture, may incline therapeutic decision towards exclusion treatments. Clinical guidelines on treatment of unruptured intracranial aneurysms in this population are still missing. We aimed to assess the safety and efficacy of the treatment of unruptured intracranial aneurysm in patients with sickle cell anemia, using an adapted hematological preparation regimen. PATIENTS AND METHODS: Adult patients with sickle cell anemia and treated unruptured aneurysms by endovascular therapy or neurosurgery were included in this retrospective cohort study. Treatment decision was reached after multi-disciplinary assessment. A pre-operative blood transfusion protocol was undertaken targeting a HbS below 30%. Demographic data, hematological preparation parameters and clinical and radiological outcomes were documented. RESULTS AND CONCLUSIONS: Twenty-five procedures were performed in 18 patients encompassing 19 aneurysms treated by embolization and 6 by surgery. Median age at treatment was 34 years-old and median aneurysm dome size was 4.4 mm. Immediate aneurysm exclusion rate was 85.7% after endovascular therapy and 100% after neurosurgery. Median follow-up was 6 months, with all patients being asymptomatic at last follow-up. Two transitory ischemic neurological deficits, as well as four cases of iodine-induced encephalopathy were identified after embolization. No complication occurred after surgery. Endovascular therapy by coiling and neurosurgical treatment of unruptured intracranial aneurysms appears to be safe in patients with sickle cell anemia and should be considered given the specific hemorrhagic risk observed in this population. A rigorous hematological preparation, associated with a dedicated peri­operative protocol and an adequate therapeutic strategy are essential prerequisites.

RESUMO

Assessing organic matter fluxes and species interactions in food webs is of main interest to understand the ecological functioning in bays and estuaries characterised by a wide diversity of primary producers and consumers. Demersal fish and cephalopod assemblages were studied across a network of 24 shallow subtidal stations in the bay of Saint-Brieuc for their diversity, stable isotope compositions and stomach contents. The community was composed of 21 taxa, eight species accounting for 94.4% of the total abundance. Three different assemblages were identified along bathymetric gradient and spatial patterns in fish dredging. Marine POM and SOM were the most likely bases of food webs regarding δ13C range displayed by fish and cephalopod without differences among assemblages. Amphipoda was the main prey item in stomachs leading to significant diet overlaps among fish species, with some variations in additional items. Sepia officinalis was characterised by a singular diet and very low dietary overlap with other species. Contrasted stable isotope values and niche overlaps among species were evidenced in the δ13C/δ15N space. Callionymus lyra and Buglossidium luteum, characterised by the widest isotopic niches, encompassed those of other species, except the singular 13C-depleted Spondyliosoma cantharus. Coupling taxonomic assemblages, stomach contents and stable isotope analyses help disentangling the resources uses and evidencing trophic pathways. Contrasts in fish and cephalopod demersal assemblages occurring at different depths not necessarily imply differences in the trophic resources uses in such complex shallow coastal ecosystems under anthropogenic influences.

RESUMO

Epilepsy is one of the leading neurological diseases in both adults and children and in spite of advancement in medical treatment, 20 to 30% of patients remain refractory to current medical treatment. Medically intractable epilepsy has a real impact on a patient's quality of life, neurologic morbidity and even mortality. Actual therapy options are an increase in drug dosage, radiosurgery, resective surgery and non-resective neuromodulatory treatments (deep brain stimulation, vagus nerve stimulation). Resective, thermoablative or neuromodulatory surgery in the treatment of epilepsy are invasive procedures, sometimes requiring long stay-in for the patients, risks of permanent neurological deficit, general anesthesia and other potential surgery-related complications such as a hemorrhage or an infection. Radiosurgical approaches can trigger radiation necrosis, brain oedema and transient worsening of epilepsy. With technology-driven developments and pursuit of minimally invasive neurosurgery, transcranial MR-guided focused ultrasound has become a valuable treatment for neurological diseases. In this critical review, we aim to give the reader a better understanding of current advancement for ultrasound in the treatment of epilepsy. By outlining the current understanding gained from both preclinical and clinical studies, this article explores the different mechanisms and potential applications (thermoablation, blood brain barrier disruption for drug delivery, neuromodulation and cortical stimulation) of high and low intensity ultrasound and compares the various possibilities available to patients with intractable epilepsy. Technical limitations of therapeutic ultrasound for epilepsy surgery are also detailed and discussed.

RESUMO

Assessing fluxes of matter and energy in food webs within and across benthic habitats is important to understand the ecological functioning in bays and estuaries, where the productivity is favoured by a wide diversity of primary producers. The temporal variability (March vs September 2019) in the carbon and nitrogen stable isotope composition of primary food sources and benthic invertebrates consumers was investigated in a large intertidal area (Western English-Channel, France). The study area is influenced by megatidal conditions and characterised by salt marshes in the sheltered part, and seasonal Ulva spp. blooms. The spatio-temporal variability in the structure of the benthic food web was analysed at the scales of both the whole bay and the different assemblages, which constitute the mosaic of habitats. Inferences on potential sources fuelling the food web were supported by spatio-temporal patterns based on covariations and stable isotope trajectory analysis. Results highlighted that phytoplankton, microphytobenthos and SOM were, most likely, the main food sources. The trophic connectivity between salt marsh and benthic habitats within the bay was limited to some macrofauna species inhabiting muddy creeks within the salt marsh. Unexpectedly, the influence of Ulva spp. blooms appeared also limited. Spatial patterns illustrates the constancy of the spatial variability in the benthic pelagic coupling, with a higher influence of microphytobenthos in the upper shore compared to low shore assemblages. This first attempt to characterize intertidal benthic food web constitutes a relevant baseline for the conservation of the bay of Saint-Brieuc where a national Nature Reserve has been created in 1998 for the conservation of overwintering birds. The spatial and temporal patterns of the benthic food web observed in this study (1) confirm the importance to consider food web variability at spatial and temporal scales from sampling designs to data analysis, and (2) demonstrate the ability of the stable isotope trajectory analysis framework to highlight food web dynamics.

RESUMO

The human cytomegalovirus (HCMV) is a ubiquitous herpes virus which infects 40 to 99% of the population. HCMV reactivation may occur in the context of immunosuppression and can induce significant morbidities. Several cases of HCMV infections or HCMV reactivation have thus been reported in glioblastoma (GBM) patients treated with radio(chemo)therapy. With the aim to identify the main risk factors associated with HCMV reactivation, we reviewed all patients treated for a newly diagnosed GBM in our institution from October 2013 to December 2015. Age, sex, Karnofsky performance status (KPS), absolute lymphocyte count (ALC), serological HCMV status, and steroid doses were recorded at the start and 1 month after the end of radiotherapy (RT). Within the 103 patients analyzed, 34 patients (33%) had an initial negative serology for HCMV, and none of them developed a seroconversion after treatment. Among patients with positive HCMV IgG (n = 69), 16 patients (23%) developed a viremia at one point during treatment. Age (> 60 years), steroid intake, and ALC (< 1500/mm3) before RT were correlated with HCMV reactivation. HCMV viremia was associated with neurological decline 1 month after chemoradiotherapy but progression-free survival was not impacted. A shorter overall survival was seen in these patients when compared with the others, but this could be biased by the older age in this subgroup. HCMV reactivation needs to be sought in case of a neurological decline during RT especially in older patients treated with steroids and low lymphocytes counts.

RESUMO

Venous thromboembolism (VTE) is a common disease complication in cancer patients and the second cause of death after cancer progression. VTE management and prophylaxis are critical in cancer patients, but effective therapy can be challenging because these patients are at higher risk of VTE recurrence and bleeding under anticoagulant treatment. Numerous published studies report inconsistent implementation of existing evidence-based clinical practice guidelines (CPG), including underutilization of thromboprophylaxis, and wide variability in clinical practice patterns across different countries and various practitioners. This review aims to summarize the 2019 ITAC-CME evidence-based CPGs for treatment and prophylaxis of cancer-related VTE, which include recommendations on the use of direct oral anticoagulants specifically in cancer patients. The guidelines underscore the gravity of developing VTE in cancer and recommend the best approaches for treating and preventing cancer-associated VTE, while minimizing unnecessary or over-treatment. Greater adherence to the 2019 ITAC guidelines could substantially decrease the burden of VTE and improve survival of cancer patients.

RESUMO

PURPOSE: The purpose of this prospective dosimetric study was to assess the dose distribution regarding the brain areas implied in cognitive functions using two approaches: volumetric modulated arc therapy (VMAT) and helical tomotherapy (HT). PATIENTS AND METHODS: Thirty-seven patients were treated using a dual-arc VMAT approach for supratentorial glioblastoma between 2016 and 2018. The total dose of 60Gy in 30 daily fractions was administered to the planning target volume (PTV). The brain structures that play an important role in cognitive physiology, such as the hippocampi, corpus callosum, cerebellum, subventricular zones (SVZ), were delineated. For each patient, a new treatment plan in HT was determined by a second medical physicist in a blindly fashion according to the same dose constraints and priorities. Statistical analyses were performed using the Wilcoxon-signed rank test. RESULTS: Conformity indexes remained similar with both techniques. The mean values were 0.96 (0.19-1.00) for VMAT and 0.98 (range, 0.84-1.00) for HT, respectively (P=0.73). Significant D50% reductions were observed with VMAT compared to HT: 14.6Gy (3.8-28.0) versus 17.4Gy (12.1-25.0) for the normal brain (P=0.014); 32.5Gy (10.3-60.0) versus 35.6Gy (17.1-58.0) for the corpus callosum (P=0.038); 8.1Gy (0.4-34.0) versus 12.8Gy (0.8-27.0) for the cerebellum (P<0.001), respectively. CONCLUSION: The VMAT approach seemed to improve the sparing of the key brain areas implied in cognitive functions without jeopardizing PTV coverage.

RESUMO

BACKGROUND: Adenoid cystic carcinoma (ACC), or cylindroma, is a rare malignancy believed to arise from epithelial cells of salivary glands. It is a slow-growing but aggressive tumor with a propensity for perineural invasion. Metastases are common to the lung, but rare to the spine. The natural history of ACC spine metastases is unknown and progression is unpredictable. METHODS: (1) A case report was described for a patient diagnosed with spine ACC metastasis of the T6/T7 vertebrae. (2) A literature search was conducted on Medline via PubMed and the Cochrane databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify articles from 1973 to March 2019 using following keywords: adenoid cystic carcinoma, cylindroma, metastasis, salivary glands. RESULTS/CASE REPORT: We report an unusual case of spine ACC metastasis of the T6/T7 vertebrae in a patient suffering from progressive radiculopathy and thoracic pain. Based on these findings, the patient underwent T6/T7 laminectomy. The diagnosis was confirmed by the pathology results. The primary parotid tumor had been resected 35 years before spine metastasis. A review of literature encompassing 40 years identified 16 patients treated for ACC spine metastases. Mean time to spine metastases was 4.1 years after primary treatment of ACC. Spine metastases were isolated, without local recurrence at the neck. CONCLUSION: This case highlights the critical importance of long follow up of ACC patients, due to late spine metastases. Diagnosis spinal metastasis of salivary carcinoma should be considered, to guide management, especially in clinical follow-up.

RESUMO

The standard medical care of glioblastoma (GBM) patients with good performance status is based on focal brain radiotherapy (40-60 Gy) with concurrent temozolomide (TMZ) followed by adjuvant TMZ. Newly diagnosed multifocal and/or multicentric GBM (M/M GBM) cases are usually treated with TMZ alone: whole brain chemoradiotherapy (CRT) is avoided for safety reasons. To our knowledge, no study has investigated the safety and efficacy of whole-brain radiotherapy (WBRT) with concurrent TMZ in M/M GBM patients. This retrospective study sought to assess the role of WBRT associated with concurrent TMZ followed by TMZ alone in this population. Eleven patients with pathologically proven M/M GBM (≥3 lobes) were treated with WBRT between April 2009 and September 2017. The median age was 50 years [34-74]. The median dose of radiotherapy was 45 Gy at 1.8 Gy per fraction over 37 days [29-41], with concurrent daily TMZ at the dose of 75 mg/m2. This treatment was followed by adjuvant monthly TMZ (150 mg/m2-D1-D5). All pathology slides and radiology images were reviewed. The median overall and progression-free survival times for all patients were 10 months [4-25] and 5 months [3-21], respectively. There was no grade 3-4 toxicity due to radiotherapy. One patient stopped the TMZ during the radiochemotherapy period and 9 patients received adjuvant TMZ with a median number of 5 cycles [2-8]. Our study supports the safety and the efficacy of WBRT with TMZ in newly diagnosed M/M GBM. Larger prospective studies are needed to support our results.

RESUMO

BACKGROUND: Pigs/bovines share with humans some of the antigens present on cardiac valves. Two such antigens are: the major xenogenic Ag, "Gal" present in all pig/bovine very close to human B-antigen of ABO-blood-group system; the minor Ag, pig histo-blood-group AH-antigen identical to human AH-antigen and present by some animals. We hypothesize that these antigens may modify the immunogenicity of the bioprosthesis and also its longevity. ABO distribution may vary between patients with low (<6 years) and high (≥15 years) bioprostheses longevity. METHODS: Single-centre registry study (Paris, France) including all degenerative porcine bioprostheses (mostly Carpentier-Edwards 2nd/3rd generation heart valves) explanted between 1985 and 1998 and some bovine bioprostheses. For period 1998-2014, all porcine bioprostheses with longevity ≥13 years (follow-up ≥29 years). Important predictive factors for bioprosthesis longevity: number, site of implantation, age were collected. Blood group and other variables were entered into an ordinal logistic regression analysis model predicting valve longevity, categorized as low (<6 years), medium (6-14.9 years), and high (≥15 years). FINDINGS: Longevity and ABO-blood group were obtained for 483 explanted porcine bioprostheses. Mean longevity was 10.2 ±â€¯3.9 years [0-28] and significantly higher for A-patients than others (P = 0.009). Using multivariate analysis, group A was a strong predictive factor of longevity (OR 2.09; P < 0.001). For the 64 explanted bovine bioprosthesis with low/medium longevity, the association, with A-group was even more significant. INTERPRETATION: Patients of A-group but not B have a higher longevity of their bioprostheses. Future graft-host phenotyping and matching may give rise to a new generation of long-lasting bioprosthesis for implantation in humans, especially for the younger population. FUND: None.

RESUMO

BACKGROUND: Glioblastomas (GBMs) induce a peritumoural vasogenic oedema impairing functional status and quality of life. Steroids reduce brain tumour-related oedema but are associated with numerous side-effects. It was reported in a retrospective series that angiotensin receptor blockers might be associated with reduced peritumoural oedema. The ASTER study is a randomised, placebo-controlled trial to assess whether or not the addition of Losartan to standard of care (SOC) can reduce steroid requirement during radiotherapy (RT) in patients with newly diagnosed GBM. PATIENTS AND METHODS: Patients with a histologically confirmed GBM after biopsy or partial surgical resection were randomised between Losartan or placebo in addition to SOC with RT and temozolomide (TMZ). The primary objective was to investigate the steroid dosage required to control brain oedema on the last day of RT in each arm. The secondary outcomes were steroids dosage 1 month after the end of RT, assessment of cerebral oedema on magnetic resonance imaging, tolerance and survival. RESULTS: Seventy-five patients were randomly assigned to receive Losartan (37 patients) or placebo (38 patients). No difference in the steroid dosage required to control brain oedema on the last day of RT, or one month after completion of RT, was seen between both arms. The incidence of adverse events was similar in both arms. Median overall survival was similar in both arms. CONCLUSIONS: Losartan, although well tolerated, does not reduce the steroid requirement in newly diagnosed GBM patients treated with concomitant RT and TMZ. Trial registration number NCT01805453 with ClinicalTrials.gov.

RESUMO

Twelve years after cardiologists and cardiac surgeons from all over the world issued the 'Drakensberg Declaration on the Control of Rheumatic Fever and Rheumatic Heart Disease in Africa', calling on the world community to address the prevention and treatment of rheumatic heart disease (RHD) through improving living conditions, to develop pilot programmes at selected sites for control of rheumatic fever and RHD, and to periodically review progress made and challenges that remain, RHD still accounts for a major proportion of cardiovascular diseases in children and young adults in low- and middle-income countries, where more than 80% of the world population live. Globally equal in prevalence to human immunodeficiency virus infection, RHD affects 33 million people worldwide. Prevention efforts have been important but have failed to eradicate the disease. At the present time, the only effective treatment for symptomatic RHD is open heart surgery, yet that life-saving cardiac surgery is woefully absent in many endemic regions. In this declaration, we propose a framework structure to create a co-ordinated and transparent international alliance to address this inequality.

RESUMO

PURPOSE: One of the major prognostic factors in the management of sepsis is the early initiation of appropriate treatment. To serve this purpose, early identification and triage of patients are crucial steps, which are still not optimal. The objective of this study was to determine whether the quick Sequential (Sepsis-related) Organ Failure Assessment (qSOFA) score is an accurate method for prehospital triaging of septic patients. We evaluated whether the use of qSOFA criteria collected by the Service Mobile d'Urgence et de Réanimation 15 (SAMU 15) regulation call center during prehospital care would facilitate appropriate intensive care unit (ICU) admission of patients with septic syndromes. METHODS: We conducted a retrospective observational register-based study using data collected between April 01 and May 31 2011. These data are based on call registry reports of calls received by the Paris Emergency regulation call centre during prehospital management of patients. All patients with suspected infection were included in the study and evaluated using qSOFA and systemic inflammatory response syndrome (SIRS) criteria. The primary outcome was Intensive Care Unit (ICU) admission. RESULTS: Among the 30 642 reports received, 141 patients with presumed sepsis were included. Twenty-two patients were admitted to an ICU. The qSOFA and SIRS scores were the same in predicting admission to an ICU (p = 0.26). The qSOFA had a sensitivity of 75% and a specificity of 68% for ICU admission whereas the SIRS had a sensitivity of 87% and a specificity of 43%. At day 28, 12 patients (9%) had died, 5 of them in the ICU. The negative predictive value reached 93% and 94% for pre-hospital qSOFA and SIRS respectively. Pre-hospital systolic blood pressure (SBP) ≤100 mmHg was significantly associated with ICU admission (OR = 4.19 [1.89-9.84]), while all other criteria were not. CONCLUSION: The current study reports no difference between the SIRS and the qSOFA scores for prehospital triage of septic patients to predict ICU admission. Both scores have comparable, pertinent, negative predictive value for ICU admission. Nevertheless, an improved score for pre-hospital triaging is needed to predict ICU admission of septic patients.

RESUMO

PURPOSE: A couple of scoring systems have been developed for risk stratification of septic patients. Their performance in the management of out-of-hospital initial care delivery is not documented. This study try to evaluate the predictive ability of Quick Sequential Organ Failure Assessment (qSOFA), Robson Screening Tool (RST), Modified Early Warning Score (MEWS) and Prehospital Early Sepsis Detection (PRESEP) scores on out of-hospital triage of septic patients, to predict intensive care unit (ICU) admission. METHODS: A retrospective study using call records received by the SAMU 15 regulation call centre including all patients with presumed septic shock was performed. The primary outcome was the admission to the ICU. RESULTS: Among the 47 000 reports received, 37 patients with presumed septic shock were included. Twenty-two patients (59%) were admitted to ICU. AUCs of qSOFA, RST, MEWS and PRESEP scores were respectively 0.40 [0.22-0.59], 0.60 [0.43-0.78], 0.66 [0.47-0.85] and 0.67 [0.51-0.84]. RST outperformed PRESEP, MEWS and qSOFA for sensitivity (1, 0.92, 0.85 and 0.62 respectively). MEWS showed better specificity than PRESEP, MRST and qSOFA (0.33, 0.29, 0.16 and 0.16). MEWS showed comparable positive predictive value than PRESEP and outperformed MRST and qSOFA (0.41, 0.41, 0.39 and 0.29 respectively). Negative predictive value of MRST outperformed PRESEP, MEWS and qSOFA (1, 0.88, 0.80 and 0.44 respectively). CONCLUSION: Our findings suggest that screening patients at SAMU 15 regulation call centre using qSOFA, MRST, MEWS and PRESEP scores to predict ICU admission is irrelevant. Development of a specific scoring system for out-of-hospital triage of septic patients is needed.
