Background: During the SARS-COV 2 pandemic, Mexico has dealt with different manifestations unrelated to the information that is disseminated in different media based on scientific evidence, which has generated anti-vaccine expressions based on information of dubious scientific quality. Objective: To determine the association between the use of information from social networks and the acceptance of the vaccine for SARS-COV2. A comparative, observational, cross-sectional and prospective study was carried out in Veracruz, Mexico, between January and April 2021, including residents of this city over 18 years of age through a non-probability sampling through virtual surveys conducted in Google forms. Results: 704 subjects were included in the study, of which 426 (60.6%) were women. 93.9% of the participants stated that they would agree to be vaccinated when appropriate. The source of information most used by those who accept the vaccination were social networks (43%), and of these, Facebook is the one they use the most (42.7%) and where they find more information about COVID (52.0%), without However, the social network in which they most frequently take your information into account is tweeter (29.4%). The OR for not accepting to be vaccinated was 0.2 (95% CI 0.08-0.6) for those who use information mainly from tweeters, as well as for those whose neighbors are their main source of information OR 17.6 (95% CI 5.4-57.4), both with value of p < 0.05. Having as the main source of information other social networks, television, radio, medical or newspaper personnel, resulted in p values> 0.05 for not accepting the vaccine. Key messages: Informal information decreases the likelihood of accepting the sarscov2 vaccine. Tweeter is a source of information that favors vaccination. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Ventilation/perfusion scan is a standard procedure in high-risk surgical patients to predict pulmonary function after surgery. Vibration response imaging is a technique that could be used in these patients. The objective of our study was to compare this imaging technique with the usual scanning technique for predicting postoperative forced expiratory volume., Methods: We assessed 48 patients with lung cancer who were candidates for lung resection. Forced spirometry, vibration response imaging, and ventilation/perfusion scan were performed in patients before surgery, and spirometry was performed after intervention., Results: We included 48 patients (43 men; mean age, 64 years) undergoing lung cancer surgery (32 lobectomies/16 pneumonectomies). On comparison of both techniques, for pneumonectomy, we found a concordance of 0.84 (95% confidence interval, 0.76-0.92) and Bland-Altman limits of agreement of -0.33 to +0.45, with an average difference of 0.064. By comparing postoperative spirometry with vibration response imaging, we found a concordance of 0.66 (95% confidence interval, 0.38-0.93) and Bland-Altman limits of agreement of -0.60 to +0.33, with an average difference of -0.13., Conclusions: The 2 techniques presented good concordance values. Vibration response imaging shows non-negligible confidence intervals. Vibration response imaging may be useful in preoperative algorithms in patients before lung cancer surgery., (Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc.

- Abstract
Background: Erlotinib has been shown to improve progression-free survival compared with chemotherapy when given as first-line treatment for Asian patients with non-small-cell lung cancer (NSCLC) with activating EGFR mutations. We aimed to assess the safety and efficacy of erlotinib compared with standard chemotherapy for first-line treatment of European patients with advanced EGFR-mutation positive NSCLC., Methods: We undertook the open-label, randomised phase 3 EURTAC trial at 42 hospitals in France, Italy, and Spain. Eligible participants were adults (> 18 years) with NSCLC and EGFR mutations (exon 19 deletion or L858R mutation in exon 21) with no history of chemotherapy for metastatic disease (neoadjuvant or adjuvant chemotherapy ending ≥ 6 months before study entry was allowed). We randomly allocated participants (1:1) according to a computer-generated allocation schedule to receive oral erlotinib 150 mg per day or 3 week cycles of standard intravenous chemotherapy of cisplatin 75 mg/m(2) on day 1 plus docetaxel (75 mg/m(2) on day 1) or gemcitabine (1250 mg/m(2) on days 1 and 8). Carboplatin (AUC 6 with docetaxel 75 mg/m(2) or AUC 5 with gemcitabine 1000 mg/m(2)) was allowed in patients unable to have cisplatin. Patients were stratified by EGFR mutation type and Eastern Cooperative Oncology Group performance status (0 vs 1 vs 2). The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. We assessed safety in all patients who received study drug (≥ 1 dose). This study is registered with ClinicalTrials.gov, number NCT00446225., Findings: Between Feb 15, 2007, and Jan 4, 2011, 174 patients with EGFR mutations were enrolled. One patient received treatment before randomisation and was thus withdrawn from the study; of the remaining patients, 86 were randomly assigned to receive erlotinib and 87 to receive standard chemotherapy. The preplanned interim analysis showed that the study met its primary endpoint; enrolment was halted, and full evaluation of the results was recommended. At data cutoff (Jan 26, 2011), median PFS was 9·7 months (95% CI 8·4-12·3) in the erlotinib group, compared with 5·2 months (4·5-5·8) in the standard chemotherapy group (hazard ratio 0·37, 95% CI 0·25-0·54; p < 0·0001). Main grade 3 or 4 toxicities were rash (11 [13%] of 84 patients given erlotinib vs none of 82 patients in the chemotherapy group), neutropenia (none vs 18 [22%]), anaemia (one [1%] vs three [4%]), and increased amino-transferase concentrations (two [2%] vs 0). Five (6%) patients on erlotinib had treatment-related severe adverse events compared with 16 patients (20%) on chemotherapy. One patient in the erlotinib group and two in the standard chemotherapy group died from treatment-related causes., Interpretation: Our findings strengthen the rationale for routine baseline tissue-based assessment of EGFR mutations in patients with NSCLC and for treatment of mutation-positive patients with EGFR tyrosine-kinase inhibitors., Funding: Spanish Lung Cancer Group, Roche Farma, Hoffmann-La Roche, and Red Temática de Investigacion Cooperativa en Cancer., (Copyright © 2012 Elsevier Ltd.

- Abstract
Background: Immunohistochemistry (IHC) with mutation-specific antibodies may be an ancillary method of detecting EGFR mutations in lung cancer patients., Methods: EGFR mutation status was analyzed by DNA assays, and compared with IHC results in five non-small-cell lung cancer (NSCLC) cell lines and tumor samples from 78 stage IV NSCLC patients., Results: IHC correctly identified del 19 in the H1650 and PC9 cell lines, L858R in H1975, and wild-type EGFR in H460 and A549, as well as wild-type EGFR in tumor samples from 22 patients. IHC with the mAb against EGFR with del 19 was highly positive for the protein in all 17 patients with a 15-bp (ELREA) deletion in exon 19, whereas in patients with other deletions, IHC was weakly positive in 3 cases and negative in 9 cases. IHC with the mAb against the L858R mutation showed high positivity for the protein in 25/27 (93%) patients with exon 21 EGFR mutations (all with L858R) but did not identify the L861Q mutation in the remaining two patients., Conclusions: IHC with mutation-specific mAbs against EGFR is a promising method for detecting EGFR mutations in NSCLC patients. However these mAbs should be validated with additional studies to clarify their possible role in routine clinical practice for screening EGFR mutations in NSCLC patients.

- Abstract
Background and Objectives: A variety of methods have been used to evaluate patients with lung cancer to define a patient cohort at high risk for postoperative mortality and respiratory complications associated with lung resection surgery. Our aim was to evaluate the utility of vibration response imaging (VRI(XP)) Operation Planning Software (O-Plan) in assessing suitability for surgical resection and for the prediction of postoperative forced expiratory volume in 1s (ppoFEV(1))., Methods: A total of 58 subjects with lung cancer underwent evaluation prior to lung resection surgery and postoperative lung function after surgery., Results: Preoperative pulmonary function tests and quantitative breath sound measurements by VRI were performed in all patients to estimate postoperative lung function. In addition, 20 patients underwent perfusion scan prior to surgery. VRI(XP) O-Plan predictions (12 pneumonectomies and 46 lobectomies) showed good correlation and concordance (Lin's coefficient) with postoperative FEV(1) (l) (r=0.865, Lin's coefficient 0.858) and FEV(1) (%) (r=0.877, Lin's coefficient 0.861) 4-6 weeks after surgery. Predicted and postoperative measured FEV(1) showed no significant differences (p>0.05). Average lung function predicted postoperative values were similar for perfusion and VRI(XP) O-Plan calculations with a correlation of 0.74 and concordance of 0.700., Conclusions: VRI(XP) O-Plan has shown high accuracy in predicting postoperative FEV(1) after lung resection surgery. Given its simplicity of operation and the non-invasive nature of VRI(XP) and O-Plan, it could be a good alternative to perfusion scan in pre-surgery assessment., (Copyright 2009 European Association for Cardio-Thoracic Surgery.

- Abstract
Background: Median survival is 10 months and 2-year survival is 20% in metastatic non-small-cell lung cancer (NSCLC) treated with platinum-based chemotherapy. A small fraction of non-squamous cell lung cancers harbor EGFR mutations, with improved outcome to gefitinib and erlotinib. Experimental evidence suggests that BRCA1 overexpression enhances sensitivity to docetaxel and resistance to cisplatin. RAP80 and Abraxas are interacting proteins that form complexes with BRCA1 and could modulate the effect of BRCA1. In order to further examine the effect of EGFR mutations and BRCA1 mRNA levels on outcome in advanced NSCLC, we performed a prospective non-randomized phase II clinical trial, testing the hypothesis that customized therapy would confer improved outcome over non-customized therapy. In an exploratory analysis, we also examined the effect of RAP80 and Abraxas mRNA levels., Methodology/principal Findings: We treated 123 metastatic non-squamous cell lung carcinoma patients using a customized approach. RNA and DNA were isolated from microdissected specimens from paraffin-embedded tumor tissue. Patients with EGFR mutations received erlotinib, and those without EGFR mutations received chemotherapy with or without cisplatin based on their BRCA1 mRNA levels: low, cisplatin plus gemcitabine; intermediate, cisplatin plus docetaxel; high, docetaxel alone. An exploratory analysis examined RAP80 and Abraxas expression. Median survival exceeded 28 months for 12 patients with EGFR mutations, and was 11 months for 38 patients with low BRCA1, 9 months for 40 patients with intermediate BRCA1, and 11 months for 33 patients with high BRCA1. Two-year survival was 73.3%, 41.2%, 15.6% and 0%, respectively. Median survival was influenced by RAP80 expression in the three BRCA1 groups. For example, for patients with both low BRCA1 and low RAP80, median survival exceeded 26 months. RAP80 was a significant factor for survival in patients treated according to BRCA1 levels (hazard ratio, 1.3 [95% CI, 1-1.7]; P = 0.05)., Conclusions/significance: Chemotherapy customized according to BRCA1 expression levels is associated with excellent median and 2-year survival for some subsets of NSCLC patients , and RAP80 could play a crucial modulating effect on this model of customized chemotherapy., Trial Registration: (ClinicalTrials.gov) NCT00883480.
