The Importance of Salty Groundwater in the Supply of Thalassotherapy: The Case of Portugal

Thalassotherapy is a balneotherapy activity with a wellness and therapeutic character, using salty water captured at sea. That activity is very similar to thermalism, which uses natural mineral water (NMW) captured in aquifer systems. In Portugal, thermalism is a well-established activity, and for a medical spa to be in operation, there is a legal requirement to have two specific professionals: a medical doctor—Clinical Director—and a hydrogeologist—Technical Director (TD). The exploitation of the NMW is the responsibility of the TD, a professional with know-how in the field of hydrogeology. Thus, this chapter presents an introduction with some fundamental concepts about thermalism and thalassotherapy, generic aspects of those activities in Portugal, and their objectives. Methodological elements are presented, followed by the main results and interpretations, with the physic-chemical characteristics of Portuguese NMWs; of very salty special groundwaters, not licensed as NMW; and sea and ocean waters. Finally, the main conclusions and several considerations are presented, in the sense that the practice of exploiting salty groundwater, in the proximity of the sea, will be a new field for the activity of hydrogeological professionals, provided that they are classified as NMW, to use in the thermalism activity

Competitiveness of the Hotel Industry: A Knowledge Management Approach

There is also an emerging research agenda on knowledge management within the hotel sector. Hotels are currently increasingly dependent on their competence to possess internal and external knowledge, making knowledge a critical resource for competitiveness and obtaining competitive advantages for innovation and differentiation of its competitors. Strategies tacit-oriented and explicit-oriented knowledge also has the dominant role in hospitality service operations. The principal goal of this study is to identify the role of knowledge management organizational processes as a determinant of competitiveness in the hotel industry, particularly how knowledge management strategies centered on the source (internal and external) and knowledge (tacit and explicit) have positive an impact on the competitiveness of hotels. We use a quantitative approach based in an email survey applied to 55 Portuguese hotels. Our results show that knowledge management strategies oriented to source and type of knowledge are critical for hotels competitiveness and obtaining competitive advantages.info:eu-repo/semantics/publishedVersio

Effects of Eight Week High-Intensity Interval Training Program Followed by a Six Week Detraining on Healthy Adult Gym-Users

The literature has reported that high-intensity training (HIIT) can effectively improve maximum oxygen uptake (VO2 max) and body composition (BC). Still, contradictory results are reported regarding its impact of HIIT training and post-period detraining on gym users. Objective: This study aimed to verify how eight weeks of HIIT affects VO2 maximum and BC in healthy gym users. Additionally, the effect of a six-week detraining period was verified. A group of 10 gym-users (mean ± SD age: 29.03 ± 6.18 years) volunteered for this randomized controlled trial (RCT). Method: A HIIT program that included exercises such as jumping air squats, burpees and jumping jacks was applied over eight weeks. After this period, a six-week detraining period was applied. To measure changes in VO2 max, the Queen’s College Step Test (QCST) was applied, while a bioimpedance scale was used to measure BC. Results: Eight weeks of HIIT seem to show a tendency to increase VO2 max and cause positive changes in BC (p ≤ 0.05) with the exception of two variables (i.e., fat-free mass and fat mass). Furthermore, the results suggest that 6 weeks of detraining may negatively affect gains resulting from the training program, particularly in VO2 max and body mass index (BMI) p ≥ 0.05. Conclusions: Eight-week HIIT program incorporating short-duration explosive exercises can positively affect VO2 max and BC in adult gym users.info:eu-repo/semantics/publishedVersio

Comparative Effectiveness of COVID-19 Vaccines in Preventing Infections and Disease Progression from SARS-CoV-2 Omicron BA.5 and BA.2, Portugal

We estimated comparative primary and booster vaccine effectiveness (VE) of SARS-CoV-2 Omicron BA.5 and BA.2 lineages against infection and disease progression. During April-June 2022, we implemented a case-case and cohort study and classified lineages using whole-genome sequencing or spike gene target failure. For the case-case study, we estimated the adjusted odds ratios (aORs) of vaccination using a logistic regression. For the cohort study, we estimated VE against disease progression using a penalized logistic regression. We observed no reduced VE for primary (aOR 1.07 [95% CI 0.93-1.23]) or booster (aOR 0.96 [95% CI 0.84-1.09]) vaccination against BA.5 infection. Among BA.5 case-patients, booster VE against progression to hospitalization was lower than that among BA.2 case-patients (VE 77% [95% CI 49%-90%] vs. VE 93% [95% CI 86%-97%]). Although booster vaccination is less effective against BA.5 than against BA.2, it offers substantial protection against progression from BA.5 infection to severe disease.The acquisition of sequencing equipment and reagents used in this study by the Instituto Nacional de Saúde Doutor Ricardo Jorge was partially funded by the HERA project (grant no. 2021/PHF/23776) supported by the European Commission through the European Centre for Disease Control, and also partially funded by the GenomePT project (grant no.

VITASENIOR-MT: a telehealth solution for the elderly focused on the interaction with TV

Remote monitoring of health parameters is a promising approach to improve the health condition and quality of life of particular groups of the population, which can also alleviate the current expenditure and demands of healthcare systems. The elderly, usually affected by chronic comorbidities, are a specific group of the population that can strongly benefit from telehealth technologies, allowing them to reach a more independent life, by living longer in their own homes. Usability of telehealth technologies and their acceptance by end-users are essential requirements for the success of telehealth implementation. Older people are resistant to new technologies or have difficulty in using them due to vision, hearing, sensory and cognition impairments. In this paper, we describe the implementation of an IoT-based telehealth solution designed specifically to address the elderly needs. The end-user interacts with a TV-set to record biometric parameters, and to receive warning and recommendations related to health and environmental sensor recordings. The familiarization of older people with the TV is expected to provide a more user-friendly interaction ensuring the effectiveness integration of the end-user in the overall telehealth solution.This work has been financially supported by the IC&DT project VITASENIOR-MT CENTRO-01-0145-FEDER- 023659 with FEDER funding through programs CENTRO2020 and FCT.info:eu-repo/semantics/publishedVersio

Cutting Forces Assessment in CNC Machining Processes: A Critical Review

Machining processes remain an unavoidable technique in the production of high-precision parts. Tool behavior is of the utmost importance in machining productivity and costs. Tool performance can be assessed by the roughness left on the machined surfaces, as well as of the forces developed during the process. There are various techniques to determine these cutting forces, such as cutting force prediction or measurement, using dynamometers and other sensor systems. This technique has often been used by numerous researchers in this area. This paper aims to give a review of the different techniques and devices for measuring the forces developed for machining processes, allowing a quick perception of the advantages and limitations of each technique, through the literature research carried out, using recently published worksThe present work was done and funded under the scope of the project ON-SURF (ANI | P2020 | POCI-01-0247-FEDER-024521, co-funded by Portugal 2020 and FEDER, through COMPETE 2020-Operational Programme for Competitiveness and Internationalisation.

Efficacy and safety of percutaneous left atrial appendage closure in chronic kidney disease patients with atrial fibrillation : results of a 7-year registry

© The Author 2017. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.INTRODUCTION AND AIMS: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, the most devastating complication being thromboembolism leading to fatal or disabling stroke. Although oral anticoagulation (OAC) is the mainstay of prevention therapy in the general population, its benefit in chronic kidney disease (CKD) patients is less well defined. End-stage renal disease patients treated with vitamin K antagonists present increased risk of bleeding, accelerated cardiovascular calcification and increased risk of calciphylaxis. Left atrial appendage closure (LAAC) is performed to prevent complications in high-risk AF patients with contraindications to OAC and in AF patients with events despite OAC.info:eu-repo/semantics/publishedVersio

Comparative complete scheme and booster effectiveness of COVID‐19 vaccines in preventing SARS‐CoV‐2 infections with SARS‐CoV‐2 Omicron (BA.1) and Delta (B.1.617.2) variants: A case–case study based on electronic health records

Background: Information on vaccine effectiveness in a context of novel variants of concern (VOC) emergence is of key importance to inform public health policies. This study aimed to estimate a measure of comparative vaccine effectiveness between Omicron (BA.1) and Delta (B.1.617.2 and sub-lineages) VOC according to vaccination exposure (primary or booster). Methods: We developed a case–case study using data on RT-PCR SARS-CoV2-positive cases notified in Portugal during Weeks 49–51, 2021. To obtain measure of comparative vaccine effectiveness, we compared the odds of vaccination in Omicron cases versus Delta using logistic regression adjusted for age group, sex, region, week of diagnosis, and laboratory of origin. Results: Higher odds of vaccination were observed in cases infected by Omicron VOC compared with Delta VOC cases for both complete primary vaccination (odds ratio [OR] = 2.1; 95% confidence interval [CI]: 1.8 to 2.4) and booster dose (OR = 5.2; 95% CI: 3.1 to 8.8), equivalent to reduction of vaccine effectiveness from 44.7% and 92.8%, observed against infection with Delta, to 6.0% (95% CI: 29.2% to 12.7%) and 62.7% (95% CI: 35.7% to 77.9%), observed against infection with Omicron, for complete primary vaccination and booster dose, respectively. Conclusion: Consistent reduction in vaccine-induced protection against infection with Omicron was observed. Complete primary vaccination may not be protective against SARS-CoV-2 infection in regions where Omicron variant is dominant.Grant no. 2021/PHF/23776; POCI-01-0145-FEDER-022184; Project ALG-D2-2021-06info:eu-repo/semantics/publishedVersio
