A Pediatric Telecardiology Service 20 years on-An exploratory study

Background: Telemedicine services are promoting more access to healthcare. Portugal was an early adopter of telemedicine to overcome both its geological barriers and the shortage of healthcare professionals. The Pediatric Cardiology Service (PCS) at Coimbra University Hospital Centre (CHUC) has been using telemedicine to increase access and coverage since 1998. Their Pediatric Telecardiology Service has been daily connecting CHUC with 13 other Portuguese national hospitals, and regularly connecting with Portuguese-speaking African countries, through a teleconsultation platform. Methods: This study aims at exploring the Pediatric Telecardiology Service's evolution, through a comprehensive assessment of the PCS's development, evolution and impact in public health, to better understand the critical factors for implementation and sustainability of telemedicine, in the context of healthcare services digitalization. A case study was performed, with cost-benefit, critical factors and organizational culture assessment. Finally, the Kingdon's framework helped to understand the implementation and scale-up process and the role of policy-making. Results: With the total of 32,685 out-patient teleconsultations, growing steadily from 1998 to 2016, the Pediatric Telecardiology Service has reached national and international recognition, being a pioneer and an active promotor of telemedicine. This telemedicine service has saved significant resources, about 1.1 million euros for the health system (e.g. in administrative and logistic costs) and approximately 419 euros per patient (considering an average of 1777 patients per year). PCS presents a dominant "Clan" culture. The Momentum's critical factors for telemedicine service implementation enabled us to understand how barriers were overcome (e.g. political forces). Willingness, perseverance and teamwork, allied with partnership with key stakeholders, were the foundation for professionals' engagement and service networking development. Its positive results, new regulations and the increasing support from the hospital board, set up a window of opportunity to establish a sustainable telemedicine service. Conclusion: The Pediatric Telecardiology Service enables real-time communication and the sharing of clinical information, overcoming many barriers (from geographical ones to shortage of healthcare professionals), improving access to specialized care both in Portugal and Africa. Motivation and teamwork, and perseverance, were key for the Pediatric Telecardiology Service to tackle the window of opportunity which created conditions for sustainability.publishersversionpublishe

A Pilot Study on the Prevalence of Micronutrient Imbalances in a Dutch General Population Cohort and the Effects of a Digital Lifestyle Program

Maintaining an adequate micronutrient status can be achieved by following a complete, diverse diet. Yet, food trends in Western countries show suboptimal consumption of healthy nutrients. In this study, we explored the prevalence of vitamin and mineral imbalances in a general population cohort of Dutch adults and evaluated the effect of a digital lifestyle program on the nutritional status and nutrition health behaviors of these individuals. A micronutrient panel was measured in 348 participants, alongside a dietary assessment. One hundred users subsequently underwent a remeasurement. We identified at least one nutritional imbalance in 301 individuals (86.5%). A total of 80% improved and normalized B6, 67% improved folate, 70% improved B12, and 86% improved vitamin D. Iron abnormalities were corrected in 75% of the participants. In conclusion, this study found that micronutrient deficiencies of easily obtainable vitamins through diet or supplementation such as B vitamins and vitamin D were more prevalent than expected in a Dutch population. This can partly be explained by insufficient consumption of food groups rich in B vitamins. Our preliminary results in those remeasured after a digitally enabled lifestyle intervention show these imbalances can be corrected with adequate behavioral support complemented with supplementation where needed

Students’ Evolving Meaning About Tangent Line with the Mediation of a Dynamic Geometry Environment and an Instructional Example Space

In this paper I report a lengthy episode from a teaching experiment in which fifteen Year 12 Greek students negotiated their definitions of tangent line to a function graph. The experiment was designed for the purpose of introducing students to the notion of derivative and to the general case of tangent to a function graph. Its design was based on previous research results on students’ perspectives on tangency, especially in their transition from Geometry to Analysis. In this experiment an instructional example space of functions was used in an electronic environment utilising Dynamic Geometry software with Function Grapher tools. Following the Vygotskian approach according to which students’ knowledge develops in specific social and cultural contexts, students’ construction of the meaning of tangent line was observed in the classroom throughout the experiment. The analysis of the classroom data collected during the experiment focused on the evolution of students’ personal meanings about tangent line of function graph in relation to: the electronic environment; the pre-prepared as well as spontaneous examples; students’ engagement in classroom discussion; and, the role of researcher as a teacher. The analysis indicated that the evolution of students’ meanings towards a more sophisticated understanding of tangency was not linear. Also it was interrelated with the evolution of the meaning they had about the inscriptions in the electronic environment; the instructional example space; the classroom discussion; and, the role of the teacher

Pro-inflammatory triggers in childhood obesity: correlation between leptin, adiponectin and high-sensitivity C-reactive protein in a group of obese Portuguese children

INTRODUCTION: Pediatric obesity is increasingly prevalent in the Portuguese population. Adipocyte dysfunction results in the expression of pro-inflammatory mediators that are responsible for the low-grade inflammatory process that characterizes obesity. OBJECTIVES: The aim of this study was to investigate the relationship between markers of adiposity, inflammation and adipokines in a Portuguese obese pediatric population. METHODS: One hundred and twenty children of both sexes, aged 6-17 years, were included in this study. The control group consisted of 41 healthy normal-weight children. The variables analyzed were age, gender, body mass index, waist circumference, fat mass percentage, high-sensitivity C-reactive protein (hs-CRP), leptin and adiponectin. RESULTS: There were significant differences between controls and obese children for all parameters analyzed. In the obese group, after controlling for age and gender, hs-CRP (p=0.041), adiponectin (p=0.019) and leptin (p<0.001) still showed significant statistical differences. A direct correlation was found between hs-CRP, leptin, body mass index and waist circumference, the strongest being with leptin (r=0.568; p<0.001). This trend remained statistically significant, regardless of gender or pubertal age. CONCLUSIONS: Considering the role of leptin, adiponectin and hs-CRP in the genesis of endothelial dysfunction, they may be used in clinical practice for risk stratification, as well as in the assessment of weight control programs

Selective activation of striatal indirect pathway suppresses levodopa induced-dyskinesias

Levodopa (L-DOPA) administration remains the gold standard therapy for Parkinson's disease (PD). Despite several pharmacological advances in the use of L-DOPA, a high proportion of chronically treated patients continues to suffer disabling involuntary movements, namely, L-DOPA-induced dyskinesias (LIDs). As part of the effort to stop these unwanted side effects, the present study used a rodent model to identify and manipulate the striatal outflow circuitry responsible for LIDs. To do so, optogenetic technology was used to activate separately the striatal direct (D1R- expressing) and indirect (D2R- expressing) pathways in a mouse model of PD. Firstly, D1-cre or A2a-cre animals received unilateral injections of neurotoxin 6-hydroxydopamine (6-OHDA) to simulate the loss of dopamine observed in PD patients. The effects of independently stimulating each pathway were tested to see if experimental dyskinesias could be induced. Secondly, dopamine depleted A2a-cre animals received systemic L-DOPA to evoke dyskinetic movements. The ability of indirect pathway optogenetic stimulation to suppress pre-established LIDs was then tested. Selective manipulation of direct pathway evoked optodyskinesias both in dopamine depleted and intact animals, but optical inhibition of these neurons failed to suppress LIDs. On the other hand, selective activation of indirect striatal projection neurons produced an immediate and reliable suppression of LIDs. Thus, a functional dissociation has been found here whereby activation of D1R- and D2R-expressing projection neurons evokes and inhibits LIDs respectively, supporting the notion of tight interaction between the two striatal efferent systems in both normal and pathological conditions. This points to the importance of maintaining an equilibrium in the activity of both striatal pathways to produce normal movement. Finally, the ability of selective indirect pathway optogenetic activation to block the expression of LIDs in an animal model of PD sheds light on intrinsic mechanisms responsible for striatal-based dyskinesias and identifies a potential therapeutic target for suppressing LIDs in PD patients.This work was supported by: Marie Slodowksa-Curie Fellowship, H2020-MSCA-IF-2014_RI:660964-ROSNPD (LFH); and by grants from the Spanish Government: SAF2015–67239-P (JAO), BES-2016-077493 (ICM); CIBERNED (JAO, LFH).

Mild hypothermia during cardiopulmonary bypass assisted CABG is associated with improved short- and long-term survival, a 18- year cohort study

Data substantiating the optimal patient body temperature during cooling procedures in cardiac operations are currently unavailable. To explore the optimal temperature strategy, we examined the association between temperature management and survival among patients during cardiopulmonary bypass assisted coronary artery bypass grafting (CABG) procedures on 30-days and 5-year postoperative survival. Adult patients (n = 5,672, 23.6% female and mean (SD) age of 66 (10) years) operated between 1997 and 2015 were included, with continuous measured intraoperative nasopharyngeal temperatures. The association between mortality and patient characteristics, laboratory parameters, the lowest intraoperative plateau temperature and intraoperative cooling/rewarming rates were examined by multivariate Cox regression analysis. Machine learning-based cluster analysis was used to identify patient subgroups based on pre-cooling parameters and explore whether specific subgroups benefitted from a particular temperature management. Mild hypothermia (32- 35°C) was independently associated with improved 30-days and 5-year survival compared to patients in other temperature categories regardless of operation year. 30 days and 5-year survival were 98% and 88% in the mild hypothermia group, whereas it amounted 93% and 80% in the severe hypothermia (<30°C). Normothermia (35-37°C) showed the lowest survival after 30 days and 5 years amounting 93% and 72%, respectively. Cluster analysis identified 8 distinct patient subgroups principally defined by gender, age, kidney function and weight. The full cohort and all patient subgroups displayed the highest survival at a temperature of 32°C. Given these associations, further prospective randomized controlled trials are needed to ascertain optimal patient temperatures during CPB

estudo da opinião dos médicos e implicações para o futuro

INTRODUCTION: The COVID-19 pandemic led to the reorganization of healthcare services and teleconsultation emerged as a solution to facilitate patient appointments. The aim of this study was to characterize, from a physician perspective, the teleconsultations carried out in the Portuguese National Health Service (SNS) during the first phase of the pandemic and to identify factors that influence the experience of the teleconsultation. MATERIAL AND METHODS: A cross-sectional analytical study was conducted based on an online survey, between July-September 2020, aimed at SNS doctors. Data on demographics, practice, attitudes and perceptions associated with the teleconsultation was collected. The adjusted prevalence ratio (aPR) was calculated to identify demographic factors and determinants of teleconsultation associated with satisfaction, use of video calls and greater motivation to carry out teleconsultations in the future. RESULTS: 2225 valid responses were obtained. Teleconsultation was carried out by 93.8% of participants in this period, 99.0% used the telephone as a form of communication and only 8.0% used a video call. A high degree of satisfaction with the teleconsultation was significantly associated with perceiving the teleconsultation as providing care with equivalent quality to a face-to-face consultation (aPR = 1.472) and being motivated to do teleconsultation after the pandemic (aPR = 4.081). Reporting clinical (aPR = 0.763) or technical difficulties (aPR = 0.666) was negatively associated with satisfaction). 70.4% of doctors would like to continue doing follow-up teleconsultations and 53.3% consider that video call technologies should always or often be used during teleconsultations. CONCLUSION: Teleconsultation seems to have potential to to become a common practice in the future. However, it is important to address clinical, technical, organizational, and legal questions and, above all, to ensure that it is a safe and valuable practice for patients.publishersversionepub_ahead_of_prin

Changes in Microbiota Profile in the Proximal Remnant Intestine in Infants Undergoing Surgery Requiring Enterostomy

Early-life gut dysbiosis has been associated with an increased risk of inflammatory, metabolic, and immune diseases later in life. Data on gut microbiota changes in infants undergoing intestinal surgery requiring enterostomy are scarce. This prospective cohort study examined the enterostomy effluent of 29 infants who underwent intestinal surgery due to congenital malformations of the gastrointestinal tract, necrotizing enterocolitis, or spontaneous intestinal perforation. Initial effluent samples were collected immediately after surgery and final effluent samples were collected three weeks later. Gut microbiota composition was analysed using real-time PCR and 16S rRNA gene sequencing. Three weeks after surgery, an increase in total bacteria number (+21%, p = 0.026), a decrease in Staphylococcus (-21%, p = 0.002) and Candida spp. (-16%, p = 0.045), and an increase in Lactobacillus (+3%, p = 0.045) and in less abundant genera belonging to the Enterobacteriales family were found. An increase in alpha diversity (Shannon's and Simpson's indexes) and significant alterations in beta diversity were observed. A correlation of necrotizing enterocolitis with higher Staphylococcus abundance and higher alpha diversity was also observed. H2-blockers and/or proton pump inhibitor therapy were positively correlated with a higher total bacteria number. In conclusion, these results suggest that positive changes occur in the gut microbiota profile of infants three weeks after intestinal surgery.info:eu-repo/semantics/publishedVersio
