Tumor budding as a risk factor for nodal metastasis in pT1 colorectal cancers: a meta-analysis
2017
Worldwide, colorectal cancer (CRC) screening programs have significantly increased the detection of submucosal (pT1) adenocarcinoma. Completion surgery may be indicated after endoscopic excision of these potentially metastasizing early cancers. However, the postsurgical prevalence of nodal implants does not exceed 15%, leading to questions concerning the clinical appropriateness of any post–endoscopy surgery. Eastern scientific societies (Japanese Society for Cancer of the Colon-Rectum, in particular) include tumor budding (TB), defined as the presence of isolated single cancer cells or clusters of fewer than 5 cancer cells at the tumor invasive front, among the variables that must be inclu…
P021 Heat working environment and risk of breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-spain case contr…
2016
Occupational exposure to heat can affect the absorption of carcinogenic chemicals into the body, and the metabolism of sexual hormones. We explored the association between occupational exposure to heat and breast, chronic lymphocytic leukaemia, colorectal, prostate, and stomach cancer in the MCC-Spain population based case-control study. Methods The analyses were based on 3047 controls, and 1499 breast, 1539 colorectal, 332 LLC, 1070 prostate, and 382 stomach cancer cases. Heat working environment from either natural or artificial sources was assessed with the MatEmEsp job-exposure matrix. Logistic regression models accounting for education, sex, geographic area, BMI (colorectal, prostate),…
A Pooled Analysis of Extremely Low-Frequency Magnetic Fields and Childhood Brain Tumors
2010
Pooled analyses may provide etiologic insight about associations between exposure and disease. In contrast to childhood leukemia, no pooled analyses of childhood brain tumors and exposure to extremely low-frequency magnetic fields (ELF-MFs) have been conducted. The authors carried out a pooled analysis based on primary data (1960–2001) from 10 studies of ELF-MF exposure and childhood brain tumors to assess whether the combined results, adjusted for potential confounding, indicated an association. The odds ratios for childhood brain tumors in ELF-MF exposure categories of 0.1–<0.2 μT, 0.2–<0.4 μT, and ≥0.4 μT were 0.95 (95% confidence interval: 0.65, 1.41), 0.70 (95% CI: 0.40, 1.22), and 1.1…
SARS‐CoV ‐2‐reactive antibody detection after SARS‐CoV ‐2 vaccination in hematopoietic stem cell transplant recipients: Prospective survey from the S…
2021
This is a multicenter prospective observational study which included a large cohort (n = 397) of allogeneic (allo-HSCT) (n = 311) and autologous (ASCT) hematopoietic stem cell transplant (n = 86) recipients who were monitored for antibody detection within 3 to 6 weeks after complete SARS-CoV-2 vaccination from February 1st 2021 to July 20th 2021. Most patients (n = 387, 97.4%) received mRNA-based vaccines. Most of recipients (93%) were vaccinated more than 1 year after transplant. Detectable SARS-CoV-2-reactive antibodies were observed in 242 (78%) of allo-HSCT and in 73 (85%) of ASCT recipients. Multivariate analysis in allo-HSCT recipients identified lymphopenia <1x109 /mL [Odds ratio (OR…
Influence of geriatric oncology consultation on the management of breast cancer in older women: A French population-based study
2014
Aim The objective of the present population-based study was to assess the impact of geriatric oncology consultation on the management of elderly patients with breast cancer and to identify the predictive factors of breast cancer treatment in this population. Methods A total of 206 women aged 75 years and older with breast cancer, diagnosed from January 2007 to December 2009 were included. The independent impact of geriatric oncology consultation on treatment was analyzed using multivariate logistic regression with adjustment for the other predictive factors of treatment. Results Patients who had a geriatric oncology consultation (19.4%) had more comorbidities (Charlson Comorbidity Index ≥1;…
Rectal cancer: Assessment of response to neoadjuvant chemoradiation by dynamic contrast-enhanced MRI
2012
Purpose To assess pretreatment functional and morphological tumor characteristics with magnetic resonance imaging (MRI) in advanced rectal carcinoma and to identify factors predicting response to neoadjuvant chemoradiation. Materials and Methods In a prospective study, 95 patients with rectal carcinoma underwent dynamic contrast-enhanced MRI before and after chemoradiation. Quantitative parameters were derived from a pharmacokinetic two-compartment model. Tumors were also characterized with regard to mucinous status at pretreatment high-resolution MRI as nonmucinous or mucinous. Response to treatment was defined as a downshift in the local tumor stage. Results The parameter k21 (contrast me…
Ambidextrous Leadership, Social Entrepreneurial Orientation, and Operational Performance
2019
In the knowledge era, new forms of organizing and managing firms emerge to adapt to new situations. One such new form of organizational management is ambidextrous leadership. Ambidextrous leadership combines opening leader behaviors, such as promoting creativity, and closing leader behaviors, such as accomplishing objectives and adhering to norms. Thus, the aim is to demonstrate that a social orientation is not at odds with measures of operational performance other than profitability. The purpose of this study is to examine how ambidextrous leadership is linked to social entrepreneurial orientation and how this in turn affects operational performance. This is done through a rigorous review …
Epidemiological survey on third molar agenesis and facial pattern among adolescents requiring orthodontic treatment
2017
Background The aim of this study was to determine the association between facial pattern according to Ricketts cephalometric analysis, and prevalence of third molar agenesis, taking subject age and gender as control variables. Material and methods An epidemiological survey was conducted based on a sample of 224 candidates for orthodontic treatment aged 12 to 24 (n=224). Third molar agenesis was recorded using Ricketts cephalometric analyses of lateral teleradiographs and panoramic radiographs. The risk for agenesis was predicted considering the 5 Vert Index parameters (facial axis, facial depth, mandibular plane angle, lower facial height and mandibular arch), facial type (brachyfacial, mes…
A multicenter observational study on the role of comorbidities in the recurrent episodes of benign paroxysmal positional vertigo
2014
Objective: Primary objective of this study was to find a statistical link between the most worldwide comorbidities affecting the elderly population (hypertension, diabetes, osteoarthrosis, osteoporosis and depression) and recurrent episodes of BPPV. Secondary objective was defining possible "groups of risk" for people suffering recurrent positional vertigo related to the presence of a well documented comorbidity. Methods: This was an observational, cross-sectional, multicenter, spontaneous, non-pharmacological study. The data of 1092 patients suffering BPPV evaluated in 11 different Departments of Otolaryngology, Otoneurology and Neurology, referring Centers for positional vertigo evaluatio…
Influence of follicle rupture and uterine contractions on intrauterine insemination outcome: a new predictive model.
2014
Objective To correlate the detection of follicle rupture and the number of uterine contractions per minute with the outcome of IUI and to build a predictive model for the outcome of IUI including these parameters. Design Retrospective cohort study. Setting Fertility clinic. Patient(s) We analyzed data from 610 women who underwent homologous or donor double IUI from 2005 to 2010 and whose data of uterine contractions or follicle rupture were recorded. Intervention(s) None. Main Outcome Measure(s) Live-birth rate. Result(s) Nine hundred seventy-nine IUI cycles were included.
