RESUMEN

BACKGROUND: Older persons living with HIV (PLWH) need routine healthcare to manage HIV and other comorbidities. This mixed methods study investigated digital equity, constituted as access, use and quality, of HIV and specialty telehealth services for PLWH > 50 years during the initial wave of the COVID-19 pandemic when services transitioned to remote care. METHODS: A survey of closed and open-ended questions was administered to 80 English (N = 63) and Spanish (N = 17) speaking PLWH receiving HIV care at an Academic Medical Center (N = 50) or a Federally Qualified Health Center (N = 30) in New York State. Quantitative analyses examined characteristics predicting telehealth use and visit quality. Qualitative analyses utilized thematic coding to reveal common experiences. Results were integrated to deepen the interpretation. RESULTS: Telehealth access and use were shaped by multiple related and unstable factors including devices and connectivity, technology literacy, and comfort including privacy concerns. Participants demonstrated their substantial effort to achieve the visit. The majority of patients with a telehealth visit perceived it as worse than an in-person visit by describing it as less interpersonal, and resulting in poorer outcomes, particularly participants with less formal education. Technology was not only a barrier to access, but also influenced perceptions of quality. CONCLUSIONS: In the COVID-19 pandemic initial wave, barriers to using telehealth were unequally distributed to those with more significant access and use challenges. Beyond these barriers, examining the components of equity indicate further challenges replicating in-person care using telehealth formats for older PLWH. Work remains to establish telehealth as both equitable and desirable for this population.

RESUMEN

LESSONS LEARNED: Treatment with temozolomide and BCNU was associated with substantial response and survival rates for patients with unresectable anaplastic glioma, suggesting potential therapeutic alternative for these patients. The optimal treatment for unresectable large anaplastic gliomas remains debated. BACKGROUND: The optimal treatment for unresectable large anaplastic gliomas remains debated. METHODS: Adult patients with histologically proven unresectable anaplastic oligodendroglioma or mixed gliomas (World Health Organization [WHO] 2007) were eligible. Treatment consisted of BCNU (150 mg/m2 ) and temozolomide (110 mg/m2 for 5 days) every 6 weeks for six cycles before radiotherapy. RESULTS: Between December 2005 and December 2009, 55 patients (median age of 53.1 years; range, 20.5-70.2) were included. Forty percent of patients presented with wild-type IDH1 gliomas, and 30% presented with methylated MGMT promoter. Median progression-free survival (PFS), centralized PFS, and overall survival (OS) were 16.6 (95% confidence interval [CI], 12.8-20.3), 15.4 (95% CI, 10.0-20.8), and 25.4 (95% CI, 17.5-33.2) months, respectively. Complete and partial responses under chemotherapy were observed for 28.3% and 17% of patients, respectively. Radiotherapy completion was achieved for 75% of patients. Preservation of functional status and self-care capability (Karnofsky performance status [KPS] ≥70) were preserved until disease progression for 69% of patients. Grade ≥ 3 toxicities were reported for 52% of patients, and three deaths were related to treatment. By multivariate analyses including age and KPS, IDH mutation was associated with better prognostic for both PFS and OS, whereas MGMT promoter methylation was associated with better OS. CONCLUSION: The association of BCNU and temozolomide upfront is active for patients with unresectable anaplastic gliomas, but toxicity limits its use.

RESUMEN

BACKGROUND: Treatment of extremity rhabdomyosarcomas (RMS) includes chemotherapy, surgery, and radiotherapy. Lymph node irradiation is recommended in the presence of regional node involvement at diagnosis. The aim of this study was to analyze the correlation between the pattern of relapse of non-metastatic extremity RMS and the initial therapies delivered. METHODS: All patients with localized extremity RMS prospectively treated in France in the MMT-95 and RMS-05 protocols were selected. Extent of disease and pattern of relapse were evaluated by clinical examination and imaging. RESULTS: We identified 59 patients with clinical characteristics corresponding to unfavorable prognostic factors. Twenty patients (34%) were considered to have lymph node involvement at diagnosis. Regional node biopsy was performed in 32 patients (54%) and modified the lymph node stage in 8 of the 59 patients (14%). Seventy-three percent of patients received radiotherapy. Fifty-two patients achieved first remission. Overall, 26 patients underwent complete tumor resection, 17 had R1 margins, and 5 were not operated due to early tumor progression. With a median follow-up of 82 months (range: 5-287), 18 relapses had occurred, at least locoregional in 12 cases. The 5­year local and nodal control rates were 73% (63-86%) and 86% (77-95%), respectively. Five-year progression-free and overall survival were 57% (95%CI [45-72%]) and 70% (95%CI [58-84%]), respectively. CONCLUSION: The main sites of extremity RMS relapse are locoregional. Nodal failures in non-irradiated fields are not uncommon. We recommend systematic biopsy of in-transit nodes, especially in alveolar RMS and/or RMS with regional positive nodes at diagnosis to ensure their negativity.

RESUMEN

STUDY OBJECTIVE: Minimally invasive surgery decreases postoperative morbidity after radical hysterectomy (RH) for early-stage cervical cancer. However, a randomized trial and large retrospective data question its safety after observing lower rates of survival than open surgery [1,2]. The causes of this higher recurrence rate are not definitely established but may result from cancer exposure to the peritoneum during vaginal section and cancerous cells' spillage enhanced by pneumoperitoneum or a uterine manipulator. The aim of this surgical video was to present a standardized step-by-step approach for robotic RH according to the recent recommendations from the ARCAGY -Group of National Investigators for the Study of Ovarian and Breast Cancers surgeon's group [3]. DESIGN: Step-by-step video demonstration of the technique. SETTING: Tertiary center specialized in gynecologic oncology and minimally invasive surgery. INTERVENTIONS: A 48-year-old woman was diagnosed with a stage IB2 endocervical adenocarcinoma (International Federation of Gynecology and Obstetrics 2018) with a tumor size of 27 mm. Surgery was planned after preoperative pulsed dose rate uterovaginal brachytherapy. Surgery was performed following 10 reproducible steps: • Pelvic sentinel node identification according to the SENTICOL-III trial • Right infundibulopelvic and round ligaments transection • Right uterine vessels transection • Parametrectomy • Right uterosacral ligament transection • Bladder mobilization • Identical left dissection • Rectovaginal space development • Colpectomy by vaginal route after complete pneumoperitoneum exsufflation • Robotic vaginal cuff closure and pelvic inspection Thorough robotically assisted vaginal cuff closure was carried out as a comparative study suggesting that abdominal closure may decrease vaginal complications and dehiscence [3]. CONCLUSION: No international recommendations for the RH approach have yet been endorsed. Patients must be clearly informed about the benefit-risk ratio of the surgical route. If a minimally invasive RH is still decided, the patient should be referred to experienced centers, and precautionary measures must be implemented [4]. Colpotomy by vaginal route without pneumoperitoneum is recommended. Uterine manipulators have to be strictly avoided. Preoperative brachytherapy has been reported in experienced centers in France with favorable histologic response with high rates of pathologic complete response (near 70%) and seems particularly worthwhile for tumor sizes ranging from 2 to 4 cm or presenting with lymphovascular invasion [5].

RESUMEN

Optimal doses of total skin electron beam therapy for mycosis fungoides remain to be established. Clinical efficiency and adverse effects of middle-dose (25 Gy) vs. low-dose (10-12 Gy) total skin electron beam therapy were retrospectively compared in a series of 14 and 12 mycosis fungoides, respectively. Overall skin response rate was 96.2% (92.9% middle-dose and 100% low-dose; not significant (NS)). Overall complete and partial skin response rates were 57.7% (42.9% middle-dose and 75% low-dose; NS) and 38.5% (50% middle-dose and 25% low-dose; NS), respectively. All responding patients relapsed after an overall median time of 5 months (7 months middle-dose vs. 4 months low-dose; p = 0.164, NS). Tolerance was equally fair in both groups, with only grade 1 and 2 adverse events observed in 100% vs. 66.7% of patients in middle-dose and low-dose groups (NS). Although no significant difference was observed, middle-dose protocol may be recommended owing to a longer relapse-free survival for a similar tolerance.

RESUMEN

Emerging contaminants (ECs) such as endocrine-disrupting chemicals (EDCs) and pharmaceuticals and personal care products (PPCPs) attracted global concern during the last decades due to their potential adverse effects on humans and ecosystems. This work is the first study to assess the spatiotemporal changes, annual fluxes and ecological risk of ECs (4 EDCs and 6 PPCPs) by different monitoring strategies (spot and passive sampling) over 12 months in a Scottish priority catchment (River Ugie, Scotland, 335 km2). Overall, the total concentration in water ranged from 1. This suggests that mitigation measures might need to be taken to reduce the input of emerging contaminants into the river and its adjacent estuary and sea.

RESUMEN

BACKGROUND: Survival of childhood, adolescent and young adult (CAYA) cancers has increased with progress in the management of the treatments and has reached more than 80% at 5 years. Nevertheless, these survivors are at great risk of second cancers and non-malignant co-morbidities in later life. DeNaCaPST is a non-interventional study whose aim is to organize a national screening for thyroid cancer and breast cancer in survivors of CAYA cancers. It will study the compliance with international recommendations, with the aim, regarding a breast screening programme, of offering for every woman living in France, at equal risk, an equal screening. METHOD: DeNaCaPST trial is coordinated by the INSERM 1018 unit in cooperation with the LEA (French Childhood Cancer Survivor Study for Leukaemia) study's coordinators, the long term follow up committee and the paediatric radiation committee of the SFCE (French Society of Childhood Cancers). A total of 35 centres spread across metropolitan France and la Reunion will participate. FCCSS (French Childhood Cancer Survivor Study), LEA and central registry will be interrogated to identify eligible patients. To participate, centers agreed to perform a complete "long-term follow-up consultations" according to good clinical practice and the guidelines of the SFCE (French Society of Children Cancers). DISCUSSION: As survival has greatly improved in childhood cancers, detection of therapy-related malignancies has become a priority even if new radiation techniques will lead to better protection for organs at risk. International guidelines have been put in place because of the evidence for increased lifetime risk of breast and thyroid cancer. DeNaCaPST is based on these international recommendations but it is important to recognize that they are based on expert consensus opinion and are supported by neither nonrandomized observational studies nor prospective randomized trials in this specific population. Over-diagnosis is a phenomenon inherent in any screening program and therefore such programs must be evaluated.

RESUMEN

The aim was to analyze arc therapy techniques according to the number and position of the brain lesions reported by comparing dynamic noncoplanar conformal arcs (DCA), two coplanar full arcs (RAC) with volumetric-modulated arc therapy (VMAT), multiple noncoplanar partial arcs with VMAT (RANC), and two full arcs with VMAT and 10° table rotation (RAT). Patients with a single lesion (n= 10), multiple lesions (n = 10) or a single lesion close to organs at risk (n = 5) and previously treated with DCA were selected. For each patient, the DCA treatment was replanned with all VMAT techniques. All DCA plans were compared with VMAT plans and evaluated in regard to the different quality indices and dosimetric parameters. For single lesion, homogeneity index (HI) better results were found for the RANC technique (0.17 ± 0.05) compared with DCA procedure (0.27± 0.05). Concerning conformity index (CI), the RAT technique gave higher and better values (0.85 ± 0.04) compared with those obtained with the DCA technique (0.77 ± 0.05). DCA improved healthy brain protection (8.35 ± 5.61 cc vs. 10.52 ± 6.40 cc for RANC) and reduced monitor unit numbers (3046 ± 374 MU vs. 4651 ± 736 for RANC), even if global room occupation was higher. For multiple lesions, VMAT techniques provided better HI (0.16) than DCA (0.24 ± 0.07). The CI was improved with RAT (0.8 ± 0.08 for RAT vs. 0.71 ± 0.08 for DCA). The V10Gy healthy brain was better protected with DCA (9.27 ± 4.57 cc). Regarding the MU numbers: RANC < RAT< RAC < DCA. For a single lesion close to OAR, RAT achieved high degrees of homogeneity (0.27 ± 0.03 vs. 0.53 ± 0.2 for DCA) and conformity (0.72± 0.06vs. 0.56 ± 0.13 for DCA) while sparing organs at risk (Dmax = 12.36 ± 1.05Gyvs. 14.12 ± 0.59 Gy for DCA, and Dmean = 3.96 ± 3.57Gyvs. 4.72 ± 3.28Gy for DCA). On the other hand, MU numbers were lower with DCA (2254 ± 190 MUvs. 3438 ± 457 MU for RANC) even if overall time was inferior with RAC. For a single lesion, DCA provide better plan considering low doses to healthy brain even if quality indexes are better for the others techniques. For multiple lesions, RANC seems to be the best compromise, due to the ability to deliver a good conformity and homogeneity plan while sparing healthy brain tissue. For a single lesion close to organs at risk, RAT is the most appropriate technique.

RESUMEN

BACKGROUND: Transcription factors are critical in regulating lens development. The AP-2 family of transcription factors functions in differentiation, cell growth and apoptosis, and in lens and eye development. AP-2α, in particular, is important in early lens development, and when conditionally deleted at the placode stage defective separation of the lens vesicle from the surface ectoderm results. AP-2α's role during later stages of lens development is unknown. To address this, the MLR10-Cre transgene was used to delete AP-2α from the lens epithelium beginning at embryonic day (E) 10.5. RESULTS: The loss of AP-2α after lens vesicle separation resulted in morphological defects beginning at E18.5. By P4, a small highly vacuolated lens with a multilayered epithelium was evident in the MLR10-AP-2α mutants. Epithelial cells appeared elongated and expressed fiber cell specific ßB1 and γ-crystallins. Epithelial cell polarity and lens cell adhesion was disrupted and accompanied by the misexpression of ZO-1, N-Cadherin, and ß-catenin. Cell death was observed in the mutant lens epithelium between postnatal day (P) 14 and P30, and correlated with altered arrangements of cells within the epithelium. CONCLUSIONS: Our findings demonstrate that AP-2α continues to be required after lens vesicle separation to maintain a normal lens epithelial cell phenotype and overall lens integrity and to ensure correct fiber cell differentiation.

RESUMEN

Diffuse WHO grade II and III gliomas (DGII/IIIG) are rare tumors, with few specific epidemiological studies. We aimed at describing the geographical distribution of a homogeneous series of histologically confirmed DGII/IIIG, over a four-year period (2006-2009), at a national level. The methodology is based on a multidisciplinary national network already established by the French Brain Tumor DataBase and data collected directly from every neuropathology department. Personal home addresses were collected for confirmed cases. For each region, the incidence of DGII/IIIG was analyzed and standardized on the age and sex distribution of the French population. The number of patients with newly diagnosed, histologically confirmed DGII/IIIG was 4,790. The overall crude rate was 19.4/10(6). To enable international comparisons, standardized rates were calculated as follows: 19.8/10(6), 18.8/10(6) and 16.0/10(6) (reference population, Europe, US and world, respectively). The geographical distribution by region showed significant differences, with higher incidence rates in Northeast and central parts of France. This work is the first studying the geographical distribution of a pure series of DGII/IIIG at a national level. It demonstrates significant heterogeneity in the distribution, and raises the question of the role of environmental and/or genetic risk(s) factor(s) for DGII/IIIG.

RESUMEN

A simple and rapid method was developed for the simultaneous analysis of nine different pesticides in water samples by gas chromatography with mass spectrometry. A number of parameters that may affect the recovery of pesticides, such as the type of solid-phase extraction cartridge, eluting solvent in single or combination and their volumes, and water pH value were investigated. It showed that three solid-phase extraction cartridges (Strata-X, Oasis HLB, and ENVI-18) produced the greatest recovery while ethyl acetate/dichloromethane/acetone (45:10:45, 12 mL) followed by dichloromethane (6 mL) was efficient in eluting target pesticides from solid-phase extraction cartridges. Different water pH values (4-9) did not show a significant effect on the pesticides recovery. The optimized method was verified by performing spiking experiments with a series of concentrations (0.002-10 µg/L) in waters, with good linearity, recovery, and reproducibility for most compounds. The limit of detection and limit of quantification of this optimized method were 0.01-2.01 and 0.02-6.71 ng/L, respectively, much lower than the European Union environmental quality standard for the pesticides (0.1 µg/L) in waters. The proposed method was further validated by participation in an interlaboratory trial. It was then subsequently applied to river waters from north-east Scotland, UK, for the determination of the target pesticides.

RESUMEN

The incidence of glioblastoma (GBM) has increased in patients aged 70 years or older, and will continue to grow. Elderly GBM patients have been excluded from most clinical trials; furthermore, optimal care management as well as benefit/risk ratio of GBM treatments are still being debated. This study describes oncological patterns of care, prognostic factors, and survival for patients ≥ 70 years in France. We identified patients over 70 with newly diagnosed and histologically confirmed GBM on data previously published by the French Brain Tumor DataBase. We included 265 patients. Neurological deficits and mental status disorders were the most frequent symptoms. The surgery consisted of resection (RS n = 95) or biopsy (B n = 170); 98 patients did not have subsequent oncological treatment. After surgery, first-line treatment consisted of radiotherapy (RT n = 76), chemotherapy (CT n = 52), and concomitant radiochemotherapy (CRC n = 39). The median age at diagnosis was 76, 74, and 73 years, respectively, for the untreated, B + RT and/or CT, RS ± RT and/or CT groups. Median survival (in days, 95 % CI) with these main strategies, when analyzed according to surgical groups, was: B-CT n = 41, 199[155-280]; B-CRC n = 21, 318[166-480]; B-RT n = 37, 149[130-214]; RS-CT n = 11, 245[211-na]; RS-CRC n = 18, 372[349-593]; RS-RT n = 39, 269[218-343]. This population study for elderly GBM patients is one of the most important in Europe, and could be considered as a historical cohort to compare future treatments. Moreover, we can hypothesize that elderly patients (versus patients <70 years) are undertreated. Karnofsky performance status seems to be the most relevant clinical predictive factor, and RS and CRC have a positive impact on survival for elderly GBM patients in the general population, at least when feasible.

RESUMEN

BACKGROUND: Total knee arthroplasty (TKA) is a commonly performed procedure to alleviate pain and improve functional limitations caused by end-stage joint damage. Effective management of postoperative pain following TKA is crucial to the prevention of complications and enhancement of recovery. Adductor canal blocks (ACB) with conventional bupivacaine (CB) provide adequate analgesia after TKA, but carry a risk of rebound pain following block resolution. Liposomal bupivacaine (LB) is an extended-release local anesthetic that can provide up to 72 h of pain relief. The objective of this study was to compare postoperative outcomes between ACBs using LB and CB after TKA. METHODS: This single institution, prospective, randomized, clinical trial enrolled patients scheduled for TKA. Participants were randomized to receive ACB with either LB or CB. Pain scores up to 72 h postoperatively were assessed as the primary outcome. Opioid consumption and length of stay were evaluated as secondary outcomes. RESULTS: A total of 80 patients were enrolled. Demographic and clinical characteristics were similar between the two groups. LB group showed significantly lower cumulative opioid use during the 72 h evaluated (P = 0.016). There were no differences in pain scores or length of stay between the groups. CONCLUSION: The study demonstrated that LB ACBs led to significantly lower opioid consumption in the days following TKA without affecting pain scores or length of stay. This finding has important implications for improving postoperative outcomes and reducing opioid use in TKA patients. Previous studies have reported inconsistent results regarding the benefits of LB, highlighting the need for further research. TRIAL REGISTRATION: This project was retrospectively registered with clinicaltrials.gov ( NCT05635916 ) on 2 December 2022.

RESUMEN

Oncostatin M (OSM), a pleiotropic cytokine of the gp130 cytokine family, has been implicated in chronic allergic inflammatory and fibrotic disease states associated with tissue eosinophilia. Mouse (m)OSM induces airway eosinophilic inflammation and interstitial pulmonary fibrosis in vivo and regulates STAT6 activation in vitro. To determine the requirement of STAT6 in OSM-induced effects in vivo, we examined wild-type (WT) and STAT6-knockout (STAT6(-/-)) C57BL/6 mouse lung responses to transient ectopic overexpression of mOSM using an adenoviral vector (AdmOSM). Intratracheal AdmOSM elicited persistent eosinophilic lung inflammation that was abolished in STAT6(-/-) mice. AdmOSM also induced pronounced pulmonary remodeling characterized by goblet cell hyperplasia and parenchymal interstitial fibrosis. Goblet cell hyperplasia was STAT6 dependent; however, parenchymal interstitial fibrosis was not. OSM also induced airway hyperresponsiveness in WT mice that was abolished in STAT6(-/-) mice. OSM stimulated an inflammatory signature in the lungs of WT mice that demonstrated STAT6-dependent regulation of Th2 cytokines (IL-4, IL-13), chemokines (eotaxin-1/2, MCP-1, keratinocyte chemoattractant), and extracellular matrix modulators (tissue inhibitor of matrix metalloproteinase-1, matrix metalloproteinase-13), but STAT6-independent regulation of IL-4Rα, total lung collagen, collagen-1A1, -1A2 mRNA, and parenchymal collagen and α smooth muscle actin accumulation. Thus, overexpression of mOSM induces STAT6-dependent pulmonary eosinophilia, mucous/goblet cell hyperplasia, and airway hyperresponsiveness but STAT6-independent mechanisms of lung tissue extracellular matrix accumulation. These results also suggest that eosinophil or neutrophil accumulation in mouse lungs is not required for OSM-induced lung parenchymal collagen deposition and that OSM may have unique roles in the pathogenesis of allergic and fibrotic lung disease.

RESUMEN

Diffuse WHO grade II (GIIG) may be unresectable when involving critical structures. To assess the feasibility and functional tolerance (cognition and quality of life) of an original therapeutic strategy combining neoadjuvant chemotherapy followed by surgical resection for initially inoperable GIIG. Ten patients underwent Temozolomide for unresectable GIIG, as initial treatment or at recurrence after previous partial resection, due to invasion of eloquent areas or bi-hemispheric diffusion preventing a total/subtotal removal. Functional outcome after both treatments was assessed, with evaluation of seven cognitive domains. Chemotherapy induced tumor shrinkage (median volume decrease 38.9%) in ipsilateral functional areas in six patients and in the contralateral hemisphere in four. Only four patients had a 1p19q codeletion. The tumor shrinkage made possible the resection (mean extent of resection 93.3%, 9 total or subtotal removals) of initially inoperable tumors. Postoperatively, three patients had no deficits, while verbal episodic memory and executive functions were slightly impaired in seven patients. However, global quality of life was roughly preserved on the EORTC QLQ C30 + BN 20 (median score: 66.7%). Role functioning score was relatively reduced (median score: 66.7%) whereas KPS was preserved (median score: 90, range 80-100). Seven patients became seizure-free while three improved. This combined treatment is feasible, efficient (surgery made possible by neoadjuvant chemotherapy) and well-tolerated (preservation of quality of life, no serious cognitive disturbances). Cognitive deficits seem mostly related to tumor location. Because KPS is not reliable enough, a detailed neuropsychological assessment should be systematically performed in GIIG.

RESUMEN

Purpose of this study was to determine the effect of waiting time for radiotherapy on overall survival of patients with glioblastoma treated in the EORTC-NCIC trial at 18 centers in France. A total of 400 adult patients with glioblastoma who were treated between January 1, 2006 and December 31, 2006 were included. There were 282 patients with "minimum criteria" according to the EORTC-NCIC trial: (i) concurrent chemotherapy with temozolomide; and (ii) age between 18 and 70 years old. Among these patients, 229 were treated with adjuvant temozolomide and were classified as "maximal criteria". One-hundred and eighteen patients were in the "without minimal criteria" group. Waiting time from the first symptom (FS-RT), pathology diagnosis (P-RT), multidisciplinary meeting (MM-RT), surgery (S-RT), and CT scan for delineation (CT-RT) until the start of radiotherapy were recorded. Median follow-up for all patients was 327 days. Overall, median FS-RT, P-RT, MM-RT, CT-RT, and S-RT times were 77, 36, 32, 12, and 41 days, respectively. Median, and 12 and 24-month overall survival were 409 days, and 56.3 ± 2.1 % and 27.6 ± 2.6 %, respectively. Univariate analysis failed to reveal a difference in survival, irrespective of the delay. In multivariate analysis, independent favorable prognostic factors for overall survival were age (p ≤ 0.0001) and type of surgery (p = 0.0006). In this large series treated during the EORTC-NCIC protocol period, waiting time until radiotherapy did not seem to affect patient outcome.

RESUMEN

Oncostatin M (OSM), a pleiotropic cytokine and a member of the gp130/IL-6 cytokine family, has been implicated in regulation of various chronic inflammatory processes. Previous work has shown that OSM induces eosinophil accumulation in mouse lungs in vivo and stimulates the eosinophil-selective chemokine eotaxin-1 synergistically with IL-4 in vitro. To examine the role of receptor regulation by OSM in synergistic eotaxin-1 responses, we here examine the modulation of the type-II IL-4 receptor (IL-4Ralpha and IL-13Ralpha1) by OSM and other gp130/IL-6 cytokine family members using NIH3T3 fibroblasts and primary mouse lung fibroblasts. We first show that OSM with either IL-13 or IL-4 synergistically induces eotaxin-1 expression in a dose-dependent fashion. Analysis of IL-4Ralpha expression at the protein (Western blot and FACS) and RNA (TAQMAN) levels showed that OSM markedly elevates expression by 3 h. OSM enhanced IL-13Ralpha1 mRNA and induced a smaller but detectable increase in total IL-13Ralpha1 protein. Priming fibroblasts with OSM for 6 h markedly enhanced subsequent IL-13 and IL-4-induced eotaxin-1 responses and STAT6 tyrosine-641 phosphorylation. Regulation of IL-4Ralpha by OSM was sensitive to inhibition of the PI3'K pathway by LY294002. These studies provide novel mechanistic insights in OSM role in regulation of synergistic eotaxin-1 responses and IL-4Ralpha expression in fibroblasts.

RESUMEN

OBJECTIVE: Time to adjuvant treatment could have an impact on cancer prognosis. It is possible that robotic surgery lengthens the healing time of vaginal cuff after minimally invasive hysterectomy. The objective of this study was to state the impact of time to RT (TTR) on prognosis in endometrial carcinoma (EC) patients and to assess variables associated with TTR. STUDY DESIGN: We conducted a multicentric retrospective study in two cancer centers. We included EC patients, between January 1996 and January 2016. We searched variables associated with TTR and impact of TTR on end-points: local recurrence-free survival, metastatic-free survival, event-free survival and overall survival. RESULTS: 329 patients were included and 279 were analyzed for TTR impact. Robotic surgery was associated with shorter TTR (8 weeks, 8.9 w for laparotomy, 9.2 w for laparoscopy). Pelvic lymphadenectomy, para-aortic lymphadenectomy, discussion in multidisciplinary meeting and treatment center was independently associated with TTR. No impact of TTR was shown on metastatic-free survival, event-free survival and overall survival but there was a trend of a decreased local recurrence rate in case of prolonged TTR (HRcontinuous variable = 1.08; CI95 %: 0.97-1.2). CONCLUSION: Our study did not show any impact of treatment delay on survival end-points although prolonged TTR could moderate the benefit of radiotherapy on local control rate. Surgical route was not associated with TTR, particularly robot-associated laparoscopy did not lengthen treatment delay. TTR seems dependent of health-care organization and could represent a quality criterion of EC care for institutions.

RESUMEN

Current and historic pesticide use has potential to compromise e.g. drinking water sources due to both primary and secondary emission sources. Understanding the spatial and temporal dynamics of emissions might help inform management decisions. To explore this potential; water, sediment and soil samples were concurrently collected from the River Ugie, Scotland over four seasons. Occurrence and fate of nine pesticides including four historic-use pesticides (HUPs): simazine, atrazine, isoproturon and permethrin, and five current-use pesticides (CUPs): metaldehyde, chlorpyrifos, chlortoluron, epoxiconazole and cypermethrin were analysed. Concentrations of target pesticides in water, sediments and soils were 4.5-45.6 ng·L-1, 0.9-4.6 ng·g-1 dw (dry weight) and 1.7-8.0 ng·g-1 dw, respectively. Concentrations of pesticides in water were found to significantly differ between seasons (p < 0.05). Significant differences in pesticide concentrations also occurred spatially within sediments (p < 0.01), indicating spatial and temporal associations with pesticide use. Sediment-water exchange showed that the sediment acts as an important secondary emission source particularly for the HUPs, while current local application and sediment emission are both major driving forces for CUPs in the riverine environment. These findings were supported by concentration ratios between different media, which showed potential as a preliminary assessment tool for identifying the source of pollutants in aquatic environments.

RESUMEN

PURPOSE: Medulloblastoma has recently been characterized as a heterogeneous disease with 4 distinct molecular subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4, with a new definition of risk stratification. We report progression-free survival, overall survival, and long-term cognitive effects in children with standard-risk medulloblastoma exclusively treated with hyperfractionated radiation therapy (HFRT), reduced boost volume, and online quality control, and we explore the prognostic value of biological characteristics in this chemotherapy-naïve population. METHODS AND MATERIALS: Patients with standard-risk medulloblastoma were enrolled in 2 successive prospective multicentric studies, MSFOP 98 and MSFOP 2007, and received exclusive HFRT (36 Gy, 1 Gy/fraction twice daily) to the craniospinal axis followed by a boost at 68 Gy restricted to the tumor bed (1.5 cm margin), with online quality assurance before treatment. Patients with MYC or MYCN amplification were not excluded at the time of the study. We report progression-free survival and overall survival in the global population, and according to molecular subgroups as per World Health Organization 2016 molecular classification, and we present cognitive evaluations based on the Wechsler scale. RESULTS: Data from 114 patients included in the MSFOP 98 trial from December 1998 to October 2001 (n = 48) and in the MSFOP 2007 from October 2008 to July 2013 (n = 66) were analyzed. With a median follow-up of 16.2 (range, 6.4-19.6) years for the MSFOP 98 cohort and 6.5 (1.6-9.6) years for the MSFOP 2007 cohort, 5-year overall survival and progression-free survival in the global population were 84% (74%-89%) and 74% (65%-81%), respectively. Molecular classification was determined for 91 patients (WNT [n = 19], SHH [n = 12], and non-WNT/non-SHH [n = 60]-including group 3 [n = 9], group 4 [n = 29], and not specified [n = 22]). Our results showed more favorable outcome for the WNT-activated subgroup and a worse prognosis for SHH-activated patients. Three patients had isolated extra-central nervous system relapse. The slope of neurocognitive decline in the global population was shallower than that observed in patients with a normofractionated regimen combined with chemotherapy. CONCLUSIONS: HFRT led to a 5-year survival rate similar to other treatments combined with chemotherapy, with a reduced treatment duration of only 6 weeks. We confirm the MSFOP 98 results and the prognostic value of molecular status in patients with medulloblastoma, even in the absence of chemotherapy. Intelligence quotient was more preserved in children with medulloblastoma who received exclusive HFRT and reduced local boost, and intelligence quotient decline was delayed compared with patients receiving standard regimen. HFRT may be appropriate for patients who do not consent to or are not eligible for prospective clinical trials; for patients from developing countries for whom aplasia or ileus may be difficult to manage in a context of high cost/effectiveness constraints; and for whom shortened duration of RT may be easier to implement.
