alexandrossfakianakis shared this article with you from Inoreader
imageObjectives: Unilateral radiation to cervical nodes has been used as a de-escalation strategy in well-lateralized tonsil cancers. The efficacy of this approach with multiple ipsilateral nodes is not established. The study hypothesis was that unilateral radiation for American Joint Committee on Cancer (AJCC)-7 T1-2N2b tonsillar cancer results in a low rate of contralateral nodal failure. Materials and Methods: This study was a retrospective chart review of patients with AJCC-7 T1-2N2b tonsillar cancer from 2 academic institutions who were treated with unilateral radiation. The primary endpoint was the contralateral nodal failure rate. Locoregional control, overall survival, and the need for gastrostomy tube placement were additional endpoints. Results: The study cohort included 66 patients treated between 2005 and 2016. The median follow-up time was 80.9 months; contralateral nodal failure occurred in 2/66 (3.0%) patients at 4.1 and 20.9 months, respectively. Both patients underwent salvage treatment with long-term subsequent survival. Overall locoregional control at both 2 and 5 years was 93.9% and the median duration of control was not reached. Overall survival at 5 years was 92.4%. Conclusions: The use of unilateral radiation for AJCC-7 T1-2N2b tonsillar cancer resulted in low rates of contralateral nodal failure. This outcome demonstrates the safety of considering unilateral radiation treatment in patients with a relatively high ipsilateral nodal burden.

The French FRACTURE database: A way to improve knowledge on management of children with very rare tumors

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Introduction

Very rare pediatric tumors (VRTs), defined by an annual incidence ≤2 per million inhabitants, represent a heterogeneous group of cancers. Due to their extremely low incidence, knowledge on these tumors is scant. Since 2012, the French Very Rare Tumors Committee (FRACTURE) database has recorded clinical data about VRTs in France. This study aims: (a) to describe the tumors registered in the FRACTURE database; and (b) to compare these data with those registered in the French National Registry of Childhood Cancer (RNCE).

Methods

Data recorded in the FRACTURE database between January 1, 2012 and December 31, 2018 were analyzed. In addition, these data were compared with those of the RNCE database between 2012 and 2015 to evaluate the completeness of the documentation and understand any discrepancies.

Results

A total of 477 patients with VRTs were registered in the FRACTURE database, representing 97 histological types. Of the 14 most common tumors registered in the RNCE (772 patients), only 19% were also registered in the FRACTURE database. Total 39% of children and adolescent VRTs registered in the RNCE and/or FRACTURE database (323 of a total of 828 patients) were not treated in or linked to a specialized pediatric oncology unit.

Conclusion

VRTs represent many different heterogenous entities, which nevertheless account for 10% of all pediatric cancers diagnosed each year. Sustainability in the collection of these rare tumor cases is therefore important, and a regular systematic collaboration between the FRACTURE database and the RNCE register helps to provide a more exhaustive picture of these VRTs and allow research completeness for some peculiar groups of patients.

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

To investigate the prognostic value of pre-treatment Controlling Nutritional Status (CONUT) score in laryngeal cancer.

Methods

Preoperative CONUT score was retrospectively calculated in 154 laryngeal cancer patients who underwent curative resection in our hospital from 2013 to 2016. The associations of CONUT with clinicopathological factors and survival were evaluated. The efficacy of CONUT score to predict prognosis was evaluated.

Results

The CONUT score was associated with body mass index (p = 0.033), neutrophil (p = 0.011), tumor size (p = 0.017), pTNM stage (p = 0.001), adjuvant radiotherapy (p < 0.001), negative pathologic factors (p < 0.001), and larynx preservation (p < 0.001). Patients with a higher CONUT score had worse overall survival (hazard ratio: 1.94, 95% confidence interval [CI]: 1.13–3.72, p = 0.039) and disease-free survival (hazard ratio: 2.16, 95% CI: 1.19–3.90, p = 0.011). The area under the curve of CONUT score (0.728) was higher than Preoperative Nutritional Index (0.72), platelet-to-lymphocyte ratio (0.675), and neutrophil-to-lymphocyte ratio (0.687).

Conclusion

The CONUT score can be useful for predicting survival in laryngeal cancer patients after curative resection.

Risk of adverse neonatal outcomes among pregnant women with disabilities

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Background
To compare risk of neonatal morbidities between women with and without documented disability and to evaluate mediation of these associations by pre-term birth and caesarean delivery.
Methods
Using data from the Consortium on Safe Labor (2002–2008; n = 223 385), we evaluated risk of 22 neonatal outcomes among singleton deliveries using ICD-9 codes to define physical (n = 1733), sensory (n = 250) and intellectual disability (n = 91). Adjusted relative risk (aRR) was estimated for each outcome among each category of disability, and among women with any disability using Poisson regression models with robust variance. Causal mediation methods evaluated pre-term birth and caesarean delivery as mediators.
Results
Compared with no disabili ty, neonates of women with any disability had higher risk of nearly all neonatal outcomes, including pre-term birth (aRR = 1.77; 95% CI 1.62–1.94), small for gestational age (SGA) (aRR = 1.25; CI 1.11–1.41), neonatal intensive care unit (NICU) admission (aRR = 1.70; CI 1.54–1.87), seizures (aRR = 2.81; CI 1.54–5.14), cardiomyopathy (aRR = 4.92; CI 1.15–20.95), respiratory morbidities (aRR ranged from 1.33–2.08) and death (aRR = 2.31; CI 1.38–3.87). Women with disabilities were more likely to have a maternal indication for pre-term delivery, including pre-pregnancy diabetes (aRR = 3.80; CI 2.84–5.08), chronic hypertension (aRR = 1.46; CI 0.95–2.25) and severe pre-eclampsia/eclampsia (aRR = 1.47; CI 1.19–1.81). Increased risk varied but was generally consistent across all disability categories. Most outcomes were partially mediated by pre-term birth, except SGA, and heightened risk remained for NICU admissions, respiratory distre ss syndrome, anaemia and a composite of any adverse outcome (aRR = 1.21; CI 1.10–1.32).
Conclusion
Neonates of women with disabilities were at higher risk of a broad range of adverse neonatal outcomes, including death. Risks were not fully explained by pre-term birth.

Efficacy of bismuth for antibiotic‐resistant Helicobacter pylori strains eradication: A systematic review and meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background & Aims

Antibiotic resistance of Helicobacter pylori (H. pylori) is increasing worldwide, and bismuth quadruple therapy has been recommended as a first-line regimen in many areas. This study aimed to investigate whether bismuth would improve the eradication rate (ER) of clarithromycin-/metronidazole-/levofloxacin-resistant H. pylori strains and how much additional efficacy bismuth could achieve.

Methods

PubMed, EMBASE, Web of Science, and Cochrane Central databases for randomized controlled trials were systematically searched by two independent reviewers until 15 January 2022. Pooled ERs of clarithromycin-/metronidazole-/levofloxacin-resistant H. pylori strains were compared between bismuth-containing and non-bismuth therapies. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model.

Results

Eight studies enrolling 340 individuals were included. The RRs of pooled ERs compared between bismuth-containing and non-bismuth therapies were 1.83 for clarithromycin-resistant strains (95% CI 1.16–2.89, pooled ER: 76.9% vs. 36.6%, p = .009, I2 = 0%), 1.39 for metronidazole-resistant strains (95% CI 1.09–1.78, pooled ER: 86.8% vs. 60.9%, p = .008, I2 = 37%), 2.75 for dual clarithromycin/metronidazole-resistant strains (95% CI 1.01–7.52, pooled ER: 76.9% vs. 18.2%, p = .05, I2 = 0%), and 1.04 for levofloxacin-resistant strains (95% CI 0.56–1.93, pooled ER: 63.4% vs. 54.3%, p = .90; I2 = 60%). Bismuth significantly increased the ERs of clarithromycin-, metronidazole-, and dual-resistant strains by 40%, 26%, and 59%, respectively. Subgroup analysis of treatment duration showed that the significantly higher eradication rate fo r antibiotic-resistant strains in bismuth-containing therapy than non-bismuth therapy was only observed in 14-day treatment regimens and not in 7-day regimens (p = .02 and .17, respectively).

Conclusions

Bismuth was most effective in improving the ERs of dual-resistant H. pylori strains, followed by clarithromycin- and metronidazole-resistant strains. Prolonged treatment duration might effectively improve the efficacy of bismuth in overcoming antibiotic resistance.

The effect of adjuvant radiotherapy on clinical outcomes in early major salivary gland cancer

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

This study investigated the effects of adjuvant radiotherapy on outcomes in early-stage major salivary gland cancers.

Methods

A total of 655 patients were identified, including 355 (54.2%) received adjuvant radiotherapy and 300 (45.8%) had surgery alone. The effect of adjuvant radiotherapy on 5-year locoregional recurrence and disease-specific survival (DSS) was calculated using the Kaplan–Meier method, Wilcoxon rank sum test, and Cox proportional hazards model.

Results

There were no significant differences in locoregional recurrence and DSS between patients receiving adjuvant radiotherapy and those not in both univariate and multivariable analysis. Although patients with positive margin status had a higher locoregional recurrence and those with moderate/poor differentiation had a worse DSS, stratified analysis still indicated there were no protective effects from the use of adjuvant radiotherapy.

Conclusions

The use of adjuvant radiation therapy was not associated with improved locoregional recurrence and DSS, even for those with high-risk histopathological factors.

Evaluation and management of paediatric vertigo

alexandrossfakianakis shared this article with you from Inoreader
imagePurpose of review This review summarizes the most current information on cause, evaluation and treatment of dizziness in children. Recent findings There has been an increased understanding of the multifactorial cause of dizziness in the paediatric population. Quantitative vestibular testing is increasingly used and valuable as a diagnostic adjunct. Vestibular rehabilitation, migraine hygiene, psychological therapies, pharmaceuticals and/or surgery can be used as well tolerated and effective treatments for vertigo in children and adolescents when tailored to cause. Summary Paediatric vertigo can be effectively evaluated through careful history taking and physical examination along with adjunctive tests, such as vestibular testing and audiometry, when appropriate. Options for treatment of vestibular disorders in children and adolescents have greatly expanded in recent years allowing for the effective management of nearly all cases of paediatric vertigo, though a multimodal and/or multidisciplinary approach is often needed.
