Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Identification of a gene signature of a pre-transformation process by senescence evasion in normal human epidermal keratinocytes

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.Background: Epidemiological data show that the incidence of carcinomas in humans is highly dependent on age. However, the initial steps of the age-related molecular oncogenic processes by which the switch towards the neoplastic state occurs remain poorly understood, mostly due to the absence of powerful models. In a previous study, we showed that normal human epidermal keratinocytes (NHEKs) spontaneously and systematically escape from senescence to give rise to pre-neoplastic emerging cells.Methods: Here, this model was used to analyze the gene expression profile associated with the early steps of age-related cell transformation. We compared the gene expression profiles of growing or senescent NHEKs to post-senescent emerging cells. Data analyses were performed by using the linear modeling features of the limma package, resulting in a two-sided t test or F-test based on moderated statistics. The p-values were adjusted for multiple testing by controlling the false discovery rate according to Benjamini Hochberg method.The common gene set resulting of differential gene expression profiles from these two comparisons revealed a post-senescence neoplastic emergence (PSNE) gene signature of 286 genes.Results: About half of these genes were already reported as involved in cancer or premalignant skin diseases. However, bioinformatics analyses did not highlight inside this signature canonical cancer pathways but metabolic pathways, including in first line the metabolism of xenobiotics by cytochrome P450. In order to validate the relevance of this signature as a signature of pretransformation by senescence evasion, we invalidated two components of the metabolism of xenobiotics by cytochrome P450, AKR1C2 and AKR1C3. When performed at the beginning of the senescence plateau, this invalidation did not alter the senescent state itself but significantly decreased the frequency of PSNE. Conversely, overexpression of AKR1C2 but not AKR1C3 increased the frequency of PSNE.Conclusions: To our knowledge, this study is the first to identify reprogrammation of metabolic pathways in normal keratinocytes as a potential determinant of the switch from senescence to pre-transformation. © 2014 Martin et al.; licensee BioMed Central Ltd.This work was supported by grants from the Association pour la Recherche sur le Cancer (ARC), the Ligue contre le Cancer, the European Regional Development Fund, the PPF Bioinfo of University Lille 1, the Europe RISC-RAD project and the Centre National de la Recherche Scientifique (CNRS)

Expression and functional assessment of candidate type 2 diabetes susceptibility genes identify four new genes contributing to human insulin secretion

Objectives: Genome-wide association studies (GWAS) have identified >100 loci independently contributing to type 2 diabetes (T2D) risk. However, translational implications for precision medicine and for the development of novel treatments have been disappointing, due to poor knowledge of how these loci impact T2D pathophysiology. Here, we aimed to measure the expression of genes located nearby T2D associated signals and to assess their effect on insulin secretion from pancreatic beta cells. Methods: The expression of 104 candidate T2D susceptibility genes was measured in a human multi-tissue panel, through PCR-free expression assay. The effects of the knockdown of beta-cell enriched genes were next investigated on insulin secretion from the human EndoC-βH1 beta-cell line. Finally, we performed RNA-sequencing (RNA-seq) so as to assess the pathways affected by the knockdown of the new genes impacting insulin secretion from EndoC-βH1, and we analyzed the expression of the new genes in mouse models with altered pancreatic beta-cell function. Results: We found that the candidate T2D susceptibility genes' expression is significantly enriched in pancreatic beta cells obtained by laser capture microdissection or sorted by flow cytometry and in EndoC-βH1 cells, but not in insulin sensitive tissues. Furthermore, the knockdown of seven T2D-susceptibility genes (CDKN2A, GCK, HNF4A, KCNK16, SLC30A8, TBC1D4, and TCF19) with already known expression and/or function in beta cells changed insulin secretion, supporting our functional approach. We showed first evidence for a role in insulin secretion of four candidate T2D-susceptibility genes (PRC1, SRR, ZFAND3, and ZFAND6) with no previous knowledge of presence and function in beta cells. RNA-seq in EndoC-βH1 cells with decreased expression of PRC1, SRR, ZFAND6, or ZFAND3 identified specific gene networks related to T2D pathophysiology. Finally, a positive correlation between the expression of Ins2 and the expression of Prc1, Srr, Zfand6, and Zfand3 was found in mouse pancreatic islets with altered beta-cell function. Conclusions: This study showed the ability of post-GWAS functional studies to identify new genes and pathways involved in human pancreatic beta-cell function and in T2D pathophysiology

Adherence to antihypertensive drug treatment in Argentina: a multicenter study.Adherence to antihypertensive drugs in Argentina.

Adherence to antihypertensive medication is an important challenge that doctors often face in the treatment of hypertension. Good adherence is crucial to prevent cardiovascular complications. In consequence, the present study aimed at determining the prevalence of adherence to antihypertensive treatment and identifying associated clinical variables. A multicenter cross-sectional study was conducted in 12 cities of Argentina. A systematic sampling was performed in order to select patients with hypertension and under pharmacological treatment for at least 6 months. Physicians took three BP measurements, and the level of adherence was assessed using the self-administered Morisky questionnaire (MMAS-8). Participants were classified into three levels of adherence: high adherence—MMAS score of 8; medium adherence—MMAS scores of 6 to <8; and low adherence—MMAS scores of <6. A total of 1111 individuals (62 ± 12 years old, women 49.4%) were included in the present analysis; 159 (14.3%), 329 (29.6%) and 623 (56.1%) patients had low, medium, and high adherence, respectively. The prevalence of controlled hypertension increased only in high adherent patients: 42.8%, 42.2%, and 64.5% for low, medium, and high adherence groups, respectively. Similarly, systolic BP was lower only in the high adherence group. High educational level (OR 3.47, 95% CI 2.68-4.49) and diuretic treatment (OR 0.64, 95% CI 0.47-0.88) were independent predictors of high adherence. In conclusion, more than a half of treated hypertensive patients had a high level of adherence. These patients had lower BP values and higher control levels. A high educational level predicts high adherence.Fil: Espeche, Walter. Hospital San Martin de la Plata; Argentina. Universidad Nacional de La Plata; ArgentinaFil: Salazar, Martin.

Nursing’s role in tuberculosis control: a discussion from the perspective of equity El rol de la enfermería em el control de la tuberculosis: uma discusión desde la perspectiva de la equidad O papel da enfermagem no controle da tuberculose: uma discussão sob a perspectiva da equidade

This paper aims to analyze nurses’ role in tuberculosis control from the perspective of equity in the context of Latin American countries. Tuberculosis is frequently associated with poverty, but many other determinants play an important role in its prevalence. Latin American countries fight against the presence of this illness and nursing professionals play a protagonist role in TB control, proposing comprehensive interventions in different spheres - individuals, families and society. The focus of nursing intervention ranges from public policy proposals, based on epidemiological research, through the establishment of multi-sector programs, to direct care and client education at the operative level. Different professional nursing institutions can play a decisive role in this problem’ integral approach, both in national and international scopes. This requires the establishment of educative, social, technical and politically integrated support networks.<br>El objetivo del presente artículo es analizar el rol de la enfermera en el control de la tuberculosis desde la perspectiva de la equidad, en el ámbito de los países latinoamericanos.
