Clinical Nutrition in Portuguese Gastroenterology Departments: A Multicentric Study.

BACKGROUND: Hospital nutrition is a major public health problem, as up to 50% of hospitalized patients suffer from undernutrition. Adequate nutritional support (NS) decreases morbidity/mortality, shortens the length of stay, and reduces costs. We aimed to evaluate the engagement of Portuguese gastroenterology departments in NS, especially in artificial nutrition (AN). METHODS: Cross-sectional multicentric study, using an online survey sent to 31 Portuguese gastroenterology departments. RESULTS: Nine centers were involved, and all departments were engaged in NS activities. The most performed nutrition technique was endoscopic gastrostomy and not all departments had the expertise to perform all nutrition procedures, namely, endoscopic jejunostomy. Two departments had an AN outpatient clinic. Five centers were involved in hospital nutrition committees. Only four performed systematic nutritional evaluation of every patient on admission. Two departments developed research in the nutrition field. An increase staff and nutrition training were pointed out as suggestions to improve NS. CONCLUSIONS: This study outlines a broad picture of NS/AN in Portuguese gastroenterology departments. Medical nutritional training and increasing nutrition teams' staff may contribute to developing NS/AN. Multidisciplinary management of nutrition-related disorders is of utmost importance, and gastroenterologists are expected to be at the core of hospital nutrition.

Impacts of Indoor Radon on Health: A Comprehensive Review on Causes, Assessment and Remediation Strategies.

Indoor radon exposure is raising concerns due to its impact on health, namely its known relationship with lung cancer. Consequently, there is an urgent need to understand the risk factors associated with radon exposure, and how this can be harmful to the health of exposed populations. This article presents a comprehensive review of studies indicating a correlation between indoor radon exposure and the higher probability of occurrence of health problems in exposed populations. The analyzed studies statistically justify this correlation between exposure to indoor radon and the incidence of lung diseases in regions where concentrations are particularly high. However, some studies also showed that even in situations where indoor radon concentrations are lower, can be found a tendency, albeit smaller, for the occurrence of negative impacts on lung cancer incidence. Lastly, regarding risk remediation, an analysis has been conducted and presented in two core perspectives: (i) focusing on the identification and application of corrective measures in pre-existing buildings, and (ii) focusing on the implementation of preventive measures during the project design and before construction, both focusing on mitigating negative impacts of indoor radon exposure on the health of populations.

Scaling behavior of public procurement activity.

Public procurement refers to the purchase by public sector entities-such as government departments or local authorities-of Services, Goods, or Works. It accounts for a significant share of OECD countries' expenditures. However, while governments are expected to execute them as efficiently as possible, there is a lack of methodologies for an adequate comparison of procurement activity between institutions at different scales, which represents a challenge for policymakers and academics. Here, we propose using methods borrowed from urban scaling laws literature to study public procurement activity among 278 Portuguese municipalities between 2011 and 2018. We find that public procurement expenditure scales sublinearly with population size, indicating an economy of scale for public spending as cities increase their population size. Moreover, when looking at the municipal Scale-Adjusted Indicators (the deviations from the scaling law) by contract categories-Works, Goods, and Services-we are able to identify a richer local characterisation of municipalities based on the similarity of procurement activity. These results make up a framework for quantitatively studying local public expenditure by enabling policymakers a more appropriate foundation for comparative analysis.

Designing an Indoor Radon Risk Exposure Indicator (IRREI): An Evaluation Tool for Risk Management and Communication in the IoT Age.

The explosive data growth in the current information age requires consistent new methodologies harmonized with the new IoT era for data analysis in a space-time context. Moreover, intuitive data visualization is a central feature in exploring, interpreting, and extracting specific insights for subsequent numerical data representation. This integrated process is normally based on the definition of relevant metrics and specific performance indicators, both computed upon continuous real-time data, considering the specificities of a particular application case for data validation. This article presents an IoT-oriented evaluation tool for Radon Risk Management (RRM), based on the design of a simple and intuitive Indoor Radon Risk Exposure Indicator (IRREI), specifically tailored to be used as a decision-making aid tool for building owners, building designers, and buildings managers, or simply as an alert flag for the problem awareness of ordinary citizens. The proposed methodology was designed for graphic representation aligned with the requirements of the current IoT age, i.e., the methodology is robust enough for continuous data collection with specific Spatio-temporal attributes and, therefore, a set of adequate Radon risk-related metrics can be extracted and proposed. Metrics are summarized considering the application case, taken as a case study for data validation, by including relevant variables to frame the study, such as the regulatory International Commission on Radiological Protection (ICRP) dosimetric limits, building occupancy (spatial dimension), and occupants' exposure periods (temporal dimension). This work has the following main contributions: (1) providing a historical perspective regarding RRM indicator evolution along time; (2) outlining both the formulation and the validation of the proposed IRREI indicator; (3) implementing an IoT-oriented methodology for an RRM indicator; and (4) a discussion on Radon risk public perception, undertaken based on the results obtained after assessment of the IRREI indicator by applying a screening questionnaire with a total of 873 valid answers.

Hemorragia digestiva alta no varicosa en portugal: un estudio multicéntrico retrospectivo en doce hospitales portugueses / Nonvariceal upper gastrointestinal bleeding in Portugal: A multicentric retrospective study in twelve Portuguese hospitals

Antecedentes La hemorragia digestiva alta no varicosa (HDANV) se asocia con un grado importante de mortalidad. Para mejorar el manejo de la HDANV es necesario recopilar más información. Los objetivos de este estudio fueron: a) caracterizar los pacientes portugueses y los enfoques clínicos utilizados para la HDANV, b) comparar el enfoque utilizado en Portugal con los enfoques generales utilizados en los otros países europeos, c) identificar los factores asociados con las opciones de tratamiento, d) identificar los factores asociados con los desenlaces adversos. Métodos ENERGiB es un estudio de cohorte, observacional y retrospectivo sobre la HDANV en el que se utilizó evaluación endoscópica y realizado en toda Europa. Este estudio se centra en los pacientes portugueses del estudio ENERGiB. Los pacientes fueron tratados mediante la pautas de atención habituales. Más tarde, se obtuvieron datos a partir de los historiales. Se realizaron análisis de multivarianza y univarianza con los factores predictivos de evolución y decisiones clínicas deficientes. Resultados Los pacientes (n=404) eran en su mayoría hombres (66,8%), con una edad media de 68 años, presencia de comorbilidades (72%), y, con frecuencia, uso de AINEs o aspirina. La mayoría fueron atendidos por médicos de familia (57,8%) o equipos quirúrgicos (20,6%), sólo el 19,4% fue tratado por equipos de gastroenterología /sangrado del IG. Los (..) (AU)

Background Nonvariceal upper gastrointestinal bleeding (NVUGIB) is associated with important mortality. More information is needed in order to improve NVUGIB management. The aims of this study were: (a) characterizing Portuguese patients and clinical approaches used in NVUGIB, (b) comparing management used in Portugal with management globally used in European countries, (c) identify factors associated with management options, and (d) identify factors associated with adverse outcome. Methods ENERGiB was an observational, retrospective cohort study, on NVUGIB with endoscopic evaluation, carried across Europe. This study focuses on Portuguese patients of the ENERGiB study. Patients were managed according to routine care. Later, data were collected from files. Multivariate/univariate analyses were conducted on predictive factors of poor outcome and clinical decisions. Results Patients (n=404) were mostly men (66.8%), mean age 68, with co-morbidities (72%), frequently on NSAIDs/aspirin. Most were assisted by general medical (57.8%) or surgical team (20.6%), only 19.4% by gastroenterology/GI-bleeding team. PPI was largely used. Gastric/duodenal ulcers, erosive gastritis and esophagitis were the main bleeding causes. 10% had bleeding persistence/recurrence. Death occurred in 24 patients, 20 from a non-bleeding related cause. Poor outcomes were related with age >65, co-morbidities, fresh blood haematemesis, shock/syncope, bleeding through previous nasogastric tube, massive fluid replacement or transfusions besides erythrocytes. Conclusions This study contributed to characterization of Portuguese patients and NVUGIB episodes in real clinical setting and identified factors associated with a poor outcome. It also identified differences, especially in the organization of GI bleeding teams, which might help us to improve the management of these patients (AU)
