Influence of COVID-19 on Patients with Esophageal Varices under Prophylactic Endoscopic Band Ligation Therapy. GE PORTUGUESE JOURNAL OF GASTROENTEROLOGY 2024; 31:182-190. [PMID: 38757062 PMCID: PMC11095607 DOI: 10.1159/000531135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Accepted: 04/25/2023] [Indexed: 05/18/2024]
Abstract
Background and Objectives Endoscopic band ligation (EBL) plays a critical role in patients with clinically significant portal hypertension, as variceal eradication (VE) is essential to prevent further variceal upper gastrointestinal bleeding (GI). The emergence of COVID-19 has led to a dramatic reduction in endoscopic activity. Our study aimed to evaluate the effect of COVID-19 on VE, GI, and 6-month mortality of patients treated with prophylactic EBL therapy. In addition, our goal was to identify the risk factors for our proposed outcomes. Methods A single-center retrospective cohort study included patients with esophageal varices treated with prophylactic EBL therapy between 2017 and 2021. To demonstrate the impact of COVID-19 on two independent groups on prophylactic EBL therapy with 1 year of follow-up, March 2019 was selected as the cut-off date. Clinical, laboratory, and endoscopic data were recovered from electronic reports. Results Ninety-seven patients underwent 398 prophylactic EBL sessions, 75 men (77.3%) with mean age 59 ± 12 years. Most achieved VE (60.8%), 14.4% had GI bleeding post-therapy, and 15.5% died at 6 months. The rate of variceal obliteration was significantly lower in the pandemic group (40.9% vs. 77.4% in the pre-pandemic group, p = 0.001). Mean number of EBL sessions and pandemic group were independently associated with incomplete VE, while MELD-Na, portal vein thrombosis and failed VE were identified as risk factors associated with mortality at 6 months. Conclusions Almost 60% of patients in the pandemic group failed to eradicate esophageal varices. Failure to achieve this result conferred a higher risk of GI bleeding and death at 6 months, the latter also significantly associated with the MELD-Na score and portal vein thrombosis. Our study is among the first to demonstrate the impact of COVID-19 in patients receiving prophylactic EBL therapy.

Abstract
Flexible esophagogastroduodenoscopy is the gold standard for removing FB of the upper gastrointestinal tract. However large sharped FB are usually challenging to remove and are the subtype that most often requires surgery. We describe a case of a patient with a dental prothesis impacted in the proximal oesophagus. After a failed conventional approach, we made a successful attempt with two regular scopes with two independent operators.

Exploring trends and autonomy levels of adaptive business intelligence in healthcare: A systematic review. PLoS One 2024; 19:e0302697. [PMID: 38728308 PMCID: PMC11086907 DOI: 10.1371/journal.pone.0302697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Accepted: 04/09/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVE In order to comprehensively understand the characteristics of Adaptive Business Intelligence (ABI) in Healthcare, this study is structured to provide insights into the common features and evolving patterns within this domain. Applying the Sheridan's Classification as a framework, we aim to assess the degree of autonomy exhibited by various ABI components. Together, these objectives will contribute to a deeper understanding of ABI implementation and its implications within the Healthcare context. METHODS A comprehensive search of academic databases was conducted to identify relevant studies, selecting AIS e-library (AISel), Decision Support Systems Journal (DSSJ), Nature, The Lancet Digital Health (TLDH), PubMed, Expert Systems with Application (ESWA) and npj Digital Medicine as information sources. Studies from 2006 to 2022 were included based on predefined eligibility criteria. PRISMA statements were used to report this study. RESULTS The outcomes showed that ABI systems present distinct levels of development, autonomy and practical deployment. The high levels of autonomy were essentially associated with predictive components. However, the possibility of completely autonomous decisions by these systems is totally excluded. Lower levels of autonomy are also observed, particularly in connection with prescriptive components, granting users responsibility in the generation of decisions. CONCLUSION The study presented emphasizes the vital connection between desired outcomes and the inherent autonomy of these solutions, highlighting the critical need for additional research on the consequences of ABI systems and their constituent elements. Organizations should deploy these systems in a way consistent with their objectives and values, while also being mindful of potential adverse effects. Providing valuable insights for researchers, practitioners, and policymakers aiming to comprehend the diverse levels of ABI systems implementation, it contributes to well-informed decision-making in this dynamic field.

Overview of Ethnobotanical-Pharmacological Studies Carried Out on Medicinal Plants from the Serra da Estrela Natural Park: Focus on Their Antidiabetic Potential. Pharmaceutics 2024; 16:454. [PMID: 38675115 PMCID: PMC11054966 DOI: 10.3390/pharmaceutics16040454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 03/19/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
The Serra da Estrela Natural Park (NPSE) in Portugal stands out as a well-preserved region abundant in medicinal plants, particularly known for their pharmaceutical applications in diabetes prevention and treatment. This comprehensive review explores these plants' botanical diversity, traditional uses, pharmacological applications, and chemical composition. The NPSE boast a rich diversity with 138 medicinal plants across 55 families identified as traditionally and pharmacologically used against diabetes globally. Notably, the Asteraceae and Lamiaceae families are prevalent in antidiabetic applications. In vitro studies have revealed their significant inhibition of carbohydrate-metabolizing enzymes, and certain plant co-products regulate genes involved in carbohydrate metabolism and insulin secretion. In vivo trials have demonstrated antidiabetic effects, including glycaemia regulation, insulin secretion, antioxidant activity, and lipid profile modulation. Medicinal plants in NPSE exhibit various activities beyond antidiabetic, such as antioxidant, anti-inflammatory, antibacterial, anti-cancer, and more. Chemical analyses have identified over fifty compounds like phenolic acids, flavonoids, terpenoids, and polysaccharides responsible for their efficacy against diabetes. These findings underscore the potential of NPSE medicinal plants as antidiabetic candidates, urging further research to develop effective plant-based antidiabetic drugs, beverages, and supplements.

Cardiolipin Membranes Promote Cytochrome c Transformation of Polycyclic Aromatic Hydrocarbons and Their In Vivo Metabolites. Molecules 2024; 29:1129. [PMID: 38474641 DOI: 10.3390/molecules29051129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/25/2024] [Accepted: 02/28/2024] [Indexed: 03/14/2024] Open
Abstract
The catalytic properties of cytochrome c (Cc) have captured great interest in respect to mitochondrial physiology and apoptosis, and hold potential for novel enzymatic bioremediation systems. Nevertheless, its contribution to the metabolism of environmental toxicants remains unstudied. Human exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with impactful diseases, and animal models have unveiled concerning signs of PAHs' toxicity to mitochondria. In this work, a series of eight PAHs with ionization potentials between 7.2 and 8.1 eV were used to challenge the catalytic ability of Cc and to evaluate the effect of vesicles containing cardiolipin mimicking mitochondrial membranes activating the peroxidase activity of Cc. With moderate levels of H2O2 and at pH 7.0, Cc catalyzed the oxidation of toxic PAHs, such as benzo[a]pyrene, anthracene, and benzo[a]anthracene, and the cardiolipin-containing membranes clearly increased the PAH conversions. Our results also demonstrate for the first time that Cc and Cc-cardiolipin complexes efficiently transformed the PAH metabolites 2-hydroxynaphthalene and 1-hydroxypyrene. In comparison to horseradish peroxidase, Cc was shown to reach more potent oxidizing states and react with PAHs with ionization potentials up to 7.70 eV, including pyrene and acenaphthene. Spectral assays indicated that anthracene binds to Cc, and docking simulations proposed possible binding sites positioning anthracene for oxidation. The results give support to the participation of Cc in the metabolism of PAHs, especially in mitochondria, and encourage further investigation of the molecular interaction between PAHs and Cc.

Abstract
Natural polysaccharides, which are described in this study, are some of the most extensively used biopolymers in food, pharmaceutical, and medical applications, because they are renewable and have a high level of biocompatibility and biodegradability. The fundamental understanding required to properly exploit polysaccharides potential in the biocomposite, nanoconjugate, and pharmaceutical industries depends on detailed research of these molecules. Polysaccharides are preferred over other polymers because of their biocompatibility, bioactivity, homogeneity, and bioadhesive properties. Natural polysaccharides have also been discovered to have excellent rheological and biomucoadhesive properties, which may be used to design and create a variety of useful and cost-effective drug delivery systems. Polysaccharide-based composites derived from natural sources have been widely exploited due to their multifunctional properties, particularly in drug delivery systems and biomedical applications. These materials have achieved global attention and are in great demand because to their biochemical properties, which mimic both human and animal cells. Although synthetic polymers account for a substantial amount of organic chemistry, natural polymers play a vital role in a range of industries, including biomedical, pharmaceutical, and construction. As a consequence, the current study will provide information on natural polymers, their biological uses, and food and pharmaceutical applications.

Abstract
OBJECTIVE Our objective was to study the relationship between epilepsy and autoimmune diseases in two different types of epilepsy: idiopathic generalized epilepsies (IGEs) and mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). The contribution of the human leukocyte antigen (HLA) system to this relationship was analyzed. METHODS Adult patients with IGEs and MTLE-HS at a tertiary epilepsy center were consecutively enrolled between January 2016 and December 2020. RESULTS A total of 664 patients, 422 with IGEs and 242 with MTLE-HS, were included. Patients with IGEs were 15 years younger, on average, than patients with MTLE-HS (p < .001). The frequency of autoimmune diseases was 5.5% (n = 23) and 4.5% (n = 11) in patients with IGEs and MTLE-HS, respectively (p = .716). The mean age of autoimmune disease onset was 20 ± 15.6 years in patients with IGEs and 36.7 ± 16.5 years in patients with MTLE-HS (p < .05). Clinical manifestations of autoimmune diseases preceded epilepsy onset in 30.4% of patients with IGEs (i.e., in early childhood); in the other patients, epilepsy appeared before autoimmune disease onset. In all but one patient with MTLE-HS and autoimmune diseases, the autoimmune diseases appeared after epilepsy onset from adolescence onward. SIGNIFICANCE Our study indicates two relationship patterns: a bidirectional association between IGEs and autoimmune diseases and a unidirectional relationship between MTLE-HS and autoimmune diseases. The involvement of genetic susceptibility factors (such as the HLA system), autoinflammatory mechanisms, female sex, and antiseizure medications in these relationships are discussed.

Abstract
INTRODUCTION AND OBJECTIVES Cardiogenic shock (CS) complicates 5-10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). METHODS Between October 2010 and December 2019, 27578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. RESULTS Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96-3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62-4.06), reinfarction (OR 0.77, 95% CI 0.15-3.90), or major bleeding (OR 1.68, 95% CI 0.75-3.74). CONCLUSION The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes.

Abstract
The wide variety of available mobile devices, associated with the increase in wireless communication network availability, enables an increasing offer of mobile and ubiquitous technologies. In this sense, this article proposes an approach called Helix-SIoT, which explores the Social Internet of Things concepts to support Blind People (BP). The objective is to enhance the treatment of the different sensors that integrate the assistance of these people with SIoT use. For this, the proposal employs Context Awareness and Multiple Criteria Decision Analysis, helping people's autonomy in terms of mobility, response times, and the choice of the Caregiver in the most transparent way possible. The functional architecture of the Helix approach operates integrated with the Adaptation and Context Recognition Subsystem of the EXEHDA middleware, which provides support for the acquisition, storage, and processing of context information used by the mobile Helix-SIoT applications.

Abstract
Abstract
Background
Progress in decreasing ischemic complications in acute coronary syndrome (ACS) has come at the expense of increased risk of bleeding. This study sought to determine the incidence, predictors, and prognosis of in-hospital bleeding (IHB) in ACS patients.
Material and methods
We retrospectively analyzed patients consecutively admitted to the coronary care unit (CCU) with ACS. Patients who suffered clinically significant IHB were compared to the remaining ACS patients. The primary endpoint was all-cause in-hospital death.
Results and conclusions
From a total of 1032 ACS patients, clinically significant IHB was identified in 5.6% (n = 58) of patients, of whom 13 patients presented serious bleeding. Patients with IHB were older (P = 0.003), more often female (P = 0.012), were more likely to have prior heart failure (P = 0.007) and chronic kidney disease (P = 0.001). At admission, they presented more often with Killip-Kimball class > I (P = 0.001), lower hemoglobin (P = 0.013), lower eGFR (P = 0.005), and a higher CRUSADE score (P < 0.001). In multivariate logistic regression, female sex (OR = 2.26, 1.17–4–38, P = 0.023), acute kidney injury (OR = 2.23, 1.12–4.45, P = 0.028), and non-radial access in coronary angiography (OR = 2.04, 1.08–3.87, P = 0.028), were identified as independent predictors of IHB.
The primary endpoint occurred in 5.8% of ACS patients. Patients who suffered IHB were at higher risk of death during hospitalization (OR = 2.39, 95% CI 1.03–5.51, P = 0.042), but not during the 2-year follow-up (P = 0.429).
In conclusion, IHB is not an uncommon complication in ACS patients and is associated with an increased risk of in-hospital mortality.

Abstract
Abstract
Background
The outcomes of dual anti-platelet therapy (DAPT), β-blocker, renin-angiotensin-aldosterone system (RAAS) inhibitor and statin therapy are unknown in patients with myocardial infarction with non-obstructive coronary arteries (MINOCA). The aim of this study was to examine the effects of secondary prevention therapy at discharge on long-term outcomes in MINOCA.
Methods
Patients with MINOCA undergoing early coronary angiography between 2009 and 2016 were extracted from a clinical database. Patients were followed until 2018 for outcome events. All patients with a MINOCA diagnosis and without history of atrial fibrillation were included. A total of 646 consecutive patients were enrolled. The primary end point was major adverse cardiac events (MACE) defined as all-cause mortality, myocardial infarction (MI), stroke, and heart failure (HF). Secondary endpoints comprised all individual endpoints for the composite end-point. The relationship between treatments and outcomes was evaluated by using Kaplan-Meier survival analysis and Cox regression models.
Results
Mean age was 67.9±13.4 years and 31.6% were women. No patient was lost to follow-up. Mean left ventricular ejection fraction was 47.8±13.1%. At discharge, 87.2%, 82.5% and 79.5% of the patients were on statins, RAAS inhibitors and β-blockers, respectively. The majority (72.8%) were discharged on DAPT. During follow-up (Mdn 59 months), 303 (46.9%) patients experienced a MACE and 208 (33.4%) died. MI occurred in 98 patients (17.8%) and stroke in 31 patients (5.6%). HF admissions were also common (82, 14.9%). The hazard ratio (HR) for major adverse cardiac events was 0.31 (0.23–0.41) in patients on statins, RAAS inhibitors and β-blockers. For patients on DAPT the HR was 0.61 (0.48–0.78). In univariate Cox regression analyses, a reduced risk of MACE was found in patients using combined secondary prevention therapies (HR 0.58, 0.46–0.74). Regarding the individual endpoints, combined secondary prevention therapy reduced the risk of stroke (HR 0.45, 0.22–0.99, P=0.04) but not risk of future MI nor HF admissions. Patients in the combined therapy group had a higher median survival (66 months, IQR 27–82 months) than the group without secondary prevention (34.5 months, IQR 6.8–74 months; P<0.001 of Log Rank test for equality of survivor functions). In a multiple Cox regression analysis including RAAS inhibitors, statins, DAPT and β-blockers in the model, none of these drugs was associated with lower MACE, except for RAAS inhibitors.
Conclusions
The results indicate long-term beneficial effects of treatment with secondary prevention medical therapies in patients with MINOCA. Properly powered randomized clinical trials are warranted.

Mesial Temporal Lobe Epilepsy (MTLE) Drug-Refractoriness Is Associated With P2X7 Receptors Overexpression in the Human Hippocampus and Temporal Neocortex and May Be Predicted by Low Circulating Levels of miR-22. Front Cell Neurosci 2022; 16:910662.

Abstract
Objective: ATP-gated ionotropic P2X7 receptors (P2X7R) actively participate in epilepsy and other neurological disorders. Neocortical nerve terminals of patients with Mesial Temporal Lobe Epilepsy with Hippocampal Sclerosis (MTLE-HS) express higher P2X7R amounts. Overexpression of P2X7R bolsters ATP signals during seizures resulting in glial cell activation, cytokines production, and GABAergic rundown with unrestrained glutamatergic excitation. In a mouse model of status epilepticus, increased expression of P2X7R has been associated with the down-modulation of the non-coding micro RNA, miR-22. MiR levels are stable in biological fluids and normally reflect remote tissue production making them ideal disease biomarkers. Here, we compared P2X7R and miR-22 expression in epileptic brains and in the serum of patients with MTLE-HS, respectively.Methods: Quantitative RT-PCR was used to evaluate the expression of P2X7R in the hippocampus and anterior temporal lobe of 23 patients with MTLE-HS and 10 cadaveric controls. Confocal microscopy and Western blot analysis were performed to assess P2X7R protein amounts. MiR-22 expression was evaluated in cell-free sera of 40 MTLE-HS patients and 48 healthy controls.Results: Nerve terminals of the hippocampus and neocortical temporal lobe of MTLE-HS patients overexpress (p < 0.05) an 85 kDa P2X7R protein whereas the normally occurring 67 kDa receptor protein dominates in the brain of the cadaveric controls. Contrariwise, miR-22 serum levels are diminished (p < 0.001) in MTLE-HS patients compared to age-matched control blood donors, a situation that is more evident in patients requiring multiple (>3) anti-epileptic drug (AED) regimens.Conclusion: Data show that there is an inverse relationship between miR-22 serum levels and P2X7R expression in the hippocampus and neocortex of MTLE-HS patients, which implies that measuring serum miR-22 may be a clinical surrogate of P2X7R brain expression in the MTLE-HS. Moreover, the high area under the ROC curve (0.777; 95% CI 0.629–0.925; p = 0.001) suggests that low miR-22 serum levels may be a sensitive predictor of poor response to AEDs among MTLE-HS patients. Results also anticipate that targeting the miR-22/P2X7R axis may be a good strategy to develop newer AEDs.

Exosomal glypican-1 discriminates pancreatic ductal adenocarcinoma from chronic pancreatitis. Dig Liver Dis 2022; 54:871-877. [PMID: 34840127 DOI: 10.1016/j.dld.2021.10.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 10/19/2021] [Accepted: 10/27/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIMS Pancreatic ductal adenocarcinoma (PDAC) diagnosis can be difficult in a chronic pancreatitis (CP) background, especially in its mass forming presentation. We aimed to assess the accuracy of glypican-1-positive circulating exosomes (GPC1+crExos) to distinguish PDAC from CP versus the state-of-the-art CA 19-9 biomarker. METHODS This was a unicentric prospective cohort. Endoscopic ultrasound with fine-needle aspiration or biopsy and blood tests (GPC1+crExos and serum CA 19-9) were performed. RESULTS The cohort comprised 60 PDAC and 29 CP (7 of which mass forming - MF) patients. Median levels of GPC1+crExos were significantly higher in PDAC (99.7%) versus CP (28.4%; p<0.0001) with an AUROC of 0.96 with 98.3% sensitivity and 86.2% specificity for a cut-off of 45.0% (p<0.0001); this outperforms CA 19-9 AUROC of 0.82 with 78.3% sensitivity and 65.5% specificity at a cut-off of 37 U/mL (p<0.0001). The superiority of% GPC1+crExos over CA 19-99 in differentiating PDAC from CP was observed in both early (stage I) and advanced tumors (stages II-IV). CONCLUSION Levels of GPC1+crExos coupled to beads enable differential diagnosis between PDAC and CP including its mass-forming presentation.

Abstract
Abstract
Study question
Does NIPGT-A have lower false-positive rates (FPR) than PGT-A?
Summary answer
When DNA from whole embryo cells was used as the gold-standard, the FPR of NIPGT-A was 3.57-times smaller than that obtained with PGT-A.
What is known already
After many years of using PGT-A, there are still many concerns, such as risks of invasive action and difficulties in the correct interpretation of mosaicism, which could lead to errors in the interpretation of false-positive and false-negative results. Recently, a new technology (NIPGT-A) has arisen using cell-free DNA present in the spent culture media of human blastocysts. Unlike PGT-A that uses only trophoblastic cells, NIPGT-A reflects the ploidy status of trophoblastic cells and inner cell mass, suggesting that this new technology could be less prone to errors and thus more reliable than invasive tests.
Study design, size, duration
This multicentric cohort study included a total of 56 blastocysts vitrified on day/5 that were previously biopsied for PGT-A(all these embryos presented a diagnosis of aneuploidy). The embryos were donated under informed consent by patients following the Human Medical Authority regulations. Blastocysts were thawed and cultured in 15μl drops of culture medium under oil. After their expansion(4-8hours), the blastocysts and their corresponding spent media were transferred to PCR tubes and stored at -20ºC until analysis.
Participants/materials, setting, methods
The DNA of all samples (spent culture medium and whole embryo) was amplified by the MALBAC® technology(Yikon Genomics). The DNA concentration of the amplified product was measured using Qubit 3.0 Fluorometer(Thermo Fisher Scientific). The samples were subjected to next-generation sequencing(NGS) using Illumina MiSeq® System. The ploidy status results obtained from ChromGo™ software(Yikon Genomics) for spent culture medium and whole embryo were compared to determine the accuracy of NIPGT-A for screening chromosomal abnormalities in each embryo.
Main results and the role of chance
DNA from all 56 spent media samples and whole embryos were successfully amplified. Comparing the results of NIPGT-A and whole embryos sequencing, the positive predictive value (PPV) was 93.5% and the FPR was 6.5% (Table 1). On the other hand, comparing the whole embryo and PGT-A results, the PPV was 76.8%, and the FPR was 23.2% (Table 2). NIPGT-A had a negative predictive value (NPV) of 100% and a false negative rate (FNR) of 0%.
Limitations, reasons for caution
Despite the sample size could be considered small, comparative analyses between the results of invasive/noninvasive PGT-A with whole embryo are rare. All donated embryos were classified as aneuploidy. Additionally, the cut-off for aneuploidy in cases of PGT-A could be variable(multicentre-study). Euploid embryos have not been donated for research to date.
Wider implications of the findings
NIPGT-A has a lower FPR than PGT-A and does not require micromanipulation skills, avoiding trophectoderm biopsy trauma and seems to provide more accurate results corresponding to the ploidy status of the whole embryo. Thereby NIPGT-A should be considered as the test of choice for genetic evaluation of the embryo.

Abstract
The ability of the Auditory Verbal Learning Test (AVLT) to lateralize hippocampal sclerosis (HS) in mesial temporal lobe epilepsy (MTLE) was explored in a sample of 50 patients with MTLE-HS (23 right and 27 left). Patients' AVLT scores were adjusted to the demographic characteristics of each individual in accordance with the Portuguese normative data. The laterality of the HS was determined by consensus by two neuroradiologists. ROC curves were used to identify the best AVLT cutoff scores to differentiate right vs. left HS. Diagnostic statistics were applied to different AVLT measures. The study results revealed that four AVLT scores can correctly classify the laterality of HS in the total sample and a sub-group of 39 right-handed patients (Edinburgh Laterality Inventory +100): delayed recall trial (76 and 80%, respectively), delayed recognition trial (64 and 67%, respectively), learning over trials index (64 and 74%, respectively), and long-term percent retention index (68 and 72%, respectively). In right-handed patients, the diagnostic capability of the delayed recall trial was improved by pairing it with the learning over trials index (accuracy of 85%). In sum, AVLT measures of verbal memory differentiate left from right HS in MTLE. The delayed recall trial demonstrated good diagnostic capacity.

Abstract
Introduction Many individuals with severe mental illness (SMI) have substance use disorder comorbidity. Dual diagnosis makes the approach and management of these patients even more challenging since the lack of improvement in either pathologies can lead to a deterioration of both. Objectives To illustrate, through the presentation of two cases, the clinical challenges in managing a patient with dual diagnosis Methods Clinical case presentation through retrospective review of clinical notes and non-systematic literature review on this topic Results We present the clinical cases of two women diagnosed with Bipolar Disorder and (poly)Substance Use Disorder since adolescence, who have a history of multiple hospitalizations due to mostly maniform symptoms. The complexity of case management is evident, both at the pharmacological level and in psychosocial intervention. This is aggravated by the difficulty in maintaining adherence to the therapeutic project and frequent relapses. Conclusions Current evidence points to the beneficial effect of a combined pharmacological and psychosocial approach, which must be comprehensive, individualized and require differentiation at various levels that are difficult to achieve and make the treatment of these situations an even greater challenge. Using illustrative examples, this review draws attention to the practical difficulties in managing situations where substance use is associated with SMI. Disclosure No significant relationships.

Abstract
Introduction Cardiovascular diseases are the leading cause of death in individuals with SMI. The sedentary lifestyle that usually guides these individuals associated with the use of some psychotropic drugs increases the risk of adverse events related to these pathologies Objectives Presentation of the Study Protocol for the Implementation of a Psychoeducational Group directed to Prevention and Monitoring Metabolic Syndrome (MS) in patients with SMI Methods It is intended to implement a psychoeducational program, which includes a 30-minute walk, focused on healthy lifestyle habits, for 16 weeks. It is intended to include SMI individuals, from a convenience sample, who present any of these criteria: Excess weight; At risk or diagnosed with DM; Sedentary lifestyle; Smoker. Data regarding socio-demographic, clinical and motivational for and about physical activity will be collected from the intervention group. Patients who refuse to join the study will only receive information about lifestyle changes at the beginning and will continue with their usual care. Results According to available literature, it is expected that the monitoring and control of these parameters will translate into a benefit in reducing cardiovascular risk factors and optimizing the treatment of MS, contributing to the empowerment of patients in managing their disease and increasing their quality and years of life. Conclusions The impact of lifestyle changes proved to be effective and are sometimes lasting, with objective gains in quality of life of these patients. The main measure to face this issue, improve the well-being and physical health of these individuals, is to reduce weight and increase baseline physical activity.

Abstract
Introduction Pregnancy and the postpartum are generally characterized by positive feelings and expectations but they may also disguise maternal stress and difficulties. These are typical periods for the onset or relapse of psychiatric symptoms and disorders. Even though suicide during pregnancy and postpartum is rare, it is among the leading causes of maternal perinatal mortality. Objectives To provide an overview on the risk of suicide during pregnancy and postpartum. Methods PubMed database was searched using combinations of the terms “suicide”, combined with “pregnancy” and “depression”. Results The major risk factors for suicidal ideation are previous suicide attempts, self-harm, current or past history of psychiatric disorder, young maternal age, being unmarried, an unplanned pregnancy, substance use disorders, lack effective psychosocial support and discontinuation of psychotropic drugs. Pregnant women with suicidality behavior have also an increased risk for various adverse obstetric outcomes, including miscarriage, preterm delivery, maternal hemorrhage, and stillbirth. Furthermore, the postpartum period is often associated with the onset of mood and psychotic disorders with an increased risk of both suicide and infanticide. Women who have suffered from serious psychiatric conditions either after childbirth or in other phases of life should be informed about the possibility of relapse after subsequent pregnancies, thus presenting a higher risk of suicide. Conclusions During pregnancy and postpartum, it is fundamental to investigate suicide risk, including suicidal ideation, thoughts, and intent, especially (but not only) in women affected by mental pathology. Moreover, maternal suicide behaviour affects the child’s neuropsychological development and can also increase the infant´s suicide risk. Disclosure No significant relationships.

Introduction
Hyperkalemia and negative chronotropic drugs are well known causes of reversible bradycardia. Their synergic combination may result in BRASH syndrome (Bradycardia, Renal failure, Atrioventricular blockade, Shock, and Hyperkalemia), a consequence of the vicious cycle between bradycardia, renal failure and worsening hyperkalemia, leading ultimately to multiorgan dysfunction. In potentially reversible bradycardia, drug discontinuation or metabolic correction is recommended before permanent pacemaker (PPM) implantation.
Objectives
To determine the long-term prognosis in patients with potentially reversible symptomatic bradycardia.
Methods
We retrospectively reviewed 176 patients who presented to the emergency department with symptomatic bradycardia, between January 2015 and August 2016. Patients without any reversible cause of bradycardia were excluded. Participants were stratified into three groups according to the reversible causes of bradycardia: patients with hyperkalemia, with or without acute renal injury (ARI) (group 1); patients taking negative chronotropic drugs, with or without ARI (group 2); patients with BRASH syndrome (combination of hyperkalemia and negative chronotropic drugs, with or without ARI) (group 3). The primary endpoint was PPM implantation after discharge. Secondary endpoints included: bradycardia-related rehospitalization, heart failure (HF) hospitalization, all-cause mortality and a composite of all the previous endpoints.
Results
A total of 105 patients were included (52.4% female; mean age 79.8±8.6 years). Group 1 was comprised by 15 patients (14.3%), group 2 by 69 patients (65.7%) and group 3 by 21 patients (20%, figure 1). The incidence of each event is presented in figure 2. During a mean follow-up of 3.2±2.1 years, PPM was implanted in 60 patients (57.1%) – 51 during hospital stay (85%) and 9 after discharge (15%). Across all groups, approximately 50% of the patients needed PPM implantation at some point, without significant differences between groups (p=0.508). Group 3 had the lowest need of in-hospital PPM (38.1%) but the highest bradycardia-related readmissions (9.5%). Nevertheless, post-discharge PPM implantation was still higher in group 1 (33.3%), followed by group 3 (22.2%). There were no significant differences in the post-discharge PPM implantation rate between groups (p=0.76). In groups 1 and 3 the composite endpoint (73.3% and 76.2%, respectively) was significantly more frequent than in group 2 (44.9%, p=0.046 and p=0.012, respectively).
Conclusions
Nearly half of the patients with an episode of reversible bradycardia needed a PPM at some point. Given the advanced age of most patients with bradycardia secondary to metabolic derangement and/or drug toxicity, it is possible that this unveils underlying conduction system disease, which is likely to recur without PPM implantation.

Background
In patients with acute coronary syndrome (ACS) the acute phase reactant, C-reactive protein (CRP), might be significantly elevated. Several reports suggest that CRP may play a direct pathophysiological role on the development and progression of atherosclerosis, and CRP values correlate with infarct size when measured by magnetic resonance imaging.
Purpose
The aim of the present study was to evaluate the prognostic value of CRP in patients presenting with an ACS.
Methods
Retrospective analysis of 635 consecutively admitted patients due to ACS in a single coronary intensive care unit. CRP levels were measured at admission. Clinical variables and therapeutic strategies were examined. The primary endpoint analysed during follow-up was all-cause mortality. Possible predictors for all-cause mortality were assessed by Cox regression models. When statistically significant values were found in univariate analysis, multivariate analysis was used to determine whether CRP was an independent predictor of outcome.
Results
In the studied sample, 75% were male. Median age was 69 [interquartile range (IQR) 57–78]. ST-elevation myocardial infarction (STEMI) occurred in 39.6%, non-ST segment elevation myocardial infarction in 44.9% and unstable angina in 15.5% of the patients. Median left ventricular ejection fraction (LVEF) was 48% (IQR 40–55%) and median CRP level at admission 0.7 mg/dL (IQR 0.5–1.9 mg/dL). Regarding important comorbidities and past medical history, 75.9% had hypertension (HTN), 34.0% diabetes, 20.3% chronic kidney disease (CKD), 68.6% dyslipidaemia and 17.3% heart failure (HF). The median follow-up was 34 months (IQR 22–72). In univariate analysis, CRP was significantly associated with all-cause mortality (HR 1.06 per 1 mg/dL increase, 95% CI 1.04–1.08, p<0.001), as was gender, age, LVEF, STEMI and previous history of diabetes, HTN, CKD or HF. In multivariate analysis, CRP remained significantly associated with the primary endpoint (HR 1.02, 95% CI 1.00–1.05, p=0.033), as did age, LVEF and previous history of HF.
Conclusions
In our study, CRP at admission was an independent risk factor for all-cause mortality following an ACS. This finding indicates that inflammation associated with the acute event has a significant impact in the long-term prognosis. More evidence is needed to determine if treating inflammation (and when, in the course of the disease) could result in better outcomes.

Abstract
Funding Acknowledgements Type of funding sources: None. Background Cardiorespiratory fitness (CRF) is a powerful predictor of all-cause mortality among individuals with coronary artery disease (CAD). A structured community-based phase III cardiac rehabilitation (CR) is very important in lifelong maintenance of phase II CRF and health gains. During the COVID-19 pandemic, CR programs had to adapt, mainly using new technologies and remote follow-up. The CRF impact in patients (Ps) who kept going their phase III program, during this troubled era is still unknown. Purpose Assess the variation in CRF and prognostic parameters in Ps with CAD who maintain high adherence levels in their phase III CR before and during the COVID-19 pandemic. Methods A cohort of Ps enrolled in a community-based phase 3 CR program, with active participation at the end of 2019, was included in this retrospective study. The inclusion criteria for this study were high levels of attendance (>80%) to the CR program before and during COVID-19 and high levels of physical activity with more than 150 mins of moderate to vigorous physical activity (MVPA). All Ps were evaluated with transthoracic echocardiography (TTE) and a cardiorespiratory exercise test (CPET) in a cycloergometer in 2019 and between october and november of 2021. All Ps had used accelerometers to measure their physical activity levels and dual-energy absorptiometry (DEXA) scan to evaluate their body composition. Between 2020 and 2021, Ps had online (in lockdown periods) and face to face exercise training sessions, 3xtimes per week, 60 mins each exercise session. A t-test paired two sample for means was used to compare CPET variables before the beginning of the first COVID lockdown (end of 2019) and after the removal of the majority of restrictions (end of 2021). Results A total of 30 Ps with high levels of adherence were included (99.6% male, 65 ± 9 years old). In this cohort, the majority had history of an ACS before the referral to the CR program (73.3%) and 55.6 ± 10.4% of left ventricular ejection fraction. There was no significant difference in body mass index (27.9 ± 3.2 kg/m2 vs 28.1 ± 3.6 kg/m2, p=0.493 but there was a significant increase in the percentage of body fat mass (30.1 ± 5.7% vs 31.0 ± 6.6%, p= 0.042). There was a maintenance on MVPA levels (352 ± 137 minutes/week vs 313 ± 194 minutes/week, p = 0.106) during this period. When comparing the 2 CPET results, Ps achieved higher exercise loads in the 2021 test (175 ± 51W vs 185 ± 52W, p=0.005), higher VO2 peak (25.3 ± 6.9 ml/kg/min vs 21.5 ± 6.3 ml/kg/min, p =0.001) and higher percentage of predicted VO2max (78.8 ± 16.8% vs 95.27 ± 20.8%, p = 0.001). Conclusion In spite of all the difficulties in maintaining a phase III CR program during the COVID-19 pandemic, we observed that in physically active CAD Ps, with the aid of new technologies and remote follow-up (during the lockdown periods) and face to face exercise sessions, it is still possible to have functional gains and improvements in CRF.

Abstract
A retrospective analysis of admissions to the pediatric emergency department that required emergency endoscopy was performed, to evaluate if changes in the lifestyle and hospital practices imposed by the pandemic had an impact on the frequency and profile of the emergency endoscopy. The first 6 months of the pandemic (Group A) were compared with the homologous period of the previous year (Group B). Eight-nine cases were analyzed. Most emergency endoscopies occurred in children under the age of two (28%) and most of these were in Group A (p = 0.009). More foreign bodies were removed in Group A (p = 0.026). There were no statistically significant differences in the time to reach the emergency department (p = 0.934) or in the time delay since emergency room admission until the endoscopic procedure (p = 0.266). Overall, the pandemic did not seem to affect the quality of healthcare practice regarding emergency endoscopic procedures.

Abstract
A indisciplina na sala de aula constitui uma das maiores preocupações para os intervenientes no processo educativo (professores, gestores de estabelecimentos de ensino, pais) e para a sociedade em geral. Este estudo tem dois objectivos essenciais: análise da relação entre variáveis de gestão da sala de aula e percepção de indisciplina; análise de perfis de resposta de professores, no que concerne à responsabilização pela indisciplina na sala de aula. Participaram no estudo 800 professores angolanos do ensino primário e secundário. Foi utilizado o Questionário de Indisciplina Percebida (Lopes & Oliveira, 2017) e a Behavior and Instructional Management Scale (Martin & Sass, 2010) para avaliar a percepção de indisciplina e a gestão da sala de aula, respectivamente. Os resultados mostram que os professores consideram que pais e alunos são os principais responsáveis pela indisciplina em sala de aula. Verificou-se ainda uma associação entre a gestão de sala de aula e atribuições de responsabilidade pela indisciplina. A análise de perfis evidencia, igualmente, padrões específicos de resposta, de professores que reportam muita, pouca e alguma indisciplina, quanto à atribuição de responsabilidades pela indisciplina. Estes resultados salientam a importância de considerar a gestão de sala de aula no estudo do comportamento dos alunos, em particular da indisciplina em sala de aula, e da perceção dos professores acerca da mesma.

Abstract
BACKGROUND Hemispherectomy has an established role as a treatment of last resort in patients with unilateral hemispheric lesions suffering from refractory epilepsy. METHODS Seven patients were evaluated at our Epilepsy Unit. We compared the seizure outcome at 6 months, 1, 2, 5 years post-surgery, as well as at end follow-up (mean 7.1 years) using Engel classification. Reduction of antiepileptic drugs (AEDs) was also assessed utilizing equal time frames. RESULTS The mean age of seizure onset was 5.4 years. Engel I was achieved in 5 patients at 6 months (71.4%). Engel at 1 year was predicted by the Engel at 6 months (p=0.013) with a similar number of patients being classified as Engel I outcome. Engel at 2 years was also predicted by Engel at 6 months and at 1 year (p=0.030). At end follow-up only 3 patients (42.9%) remained categorized as Engel I outcome. There was a trend toward a stability in Engel classification. All patients with developmental causes for their epilepsy experienced some deterioration of the surgical outcomes. Conversely, all patients with acquired causes were stable throughout follow-up. Seizure outcome at 6 months was worse in the patients who had post-op complications (p=0.044). Adult and pediatric populations did not differ significantly in any tested variable. CONCLUSIONS Hemispherectomy is a valuable resource for seizure control in properly selected patients. Engel patient's evolution could be predicted at 6 months interval. Hemispherectomy could be considered a useful attitude in difficult cases.

Abstract
Aim: To compare outcomes of coronary computed tomography angiography (CCTA) with that of functional testing (FT) in stable coronary artery disease. Methods: We searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs). A random-effects meta-analysis targeting all-cause death and nonfatal acute coronary syndromes was performed. Results: Eight RCTs enrolling 29,579 patients were included. Pooled relative risk (RR) for the primary end point was similar between CCTA and FT (RR = 0.97; 95% CI: 0.76-1.22). CCTA outperformed FT in nonfatal myocardial infarction (MI) (RR = 0.59; 95% CI: 0.41-0.83) and in downstream testing (OR: 0.47; 95% CI: 0.21-1.01). Conclusion: Updated data of stable coronary artery disease suggests that CCTA improved nonfatal MI and downstream testing.

Battery Ingestion in Children, an Ongoing Challenge: Recent Experience of a Tertiary Center. Front Pediatr 2022; 10:848092. [PMID: 35573958 PMCID: PMC9091558 DOI: 10.3389/fped.2022.848092] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 03/21/2022] [Indexed: 12/20/2022] Open
Abstract
INTRODUCTION Morbidity related to childhood battery ingestions (BI) has increased recently due to the expanding use of larger lithium cells. A prompt endoscopic removal is vital to prevent severe complications in cases of esophageal batteries (EB). MATERIALS AND METHODS A retrospective, descriptive study of admissions for BI requiring endoscopic removal in a tertiary hospital's pediatric emergency department (Jan. 2011/Dec. 2020). RESULTS We had 35 cases, with an increasing incidence in the last 6 years; median age, 26 m (8 m-10 years), witnessed ingestion in 86%. On the X-ray: 14 (40%) had an EB, 21 (60%), a gastric battery (GB). Symptoms were present in 57% (100% EB/24% GB), and vomiting was the most frequent (50%). Endoscopy revealed: EB, 13 (37%); GB, 17 (49%); duodenal battery, 1 (3%); no battery, 4 (11%). Median time to removal: EB, 7 h (2 h-21days); GB, 12 h (2 h-3 days). All the patients with EB on the X-ray (14) had severe mucosal injury (Zargar classification): Grade IIIa, 7 (50%); IIIb, 5 (36%); IV, 2 (14%). CT-scan showed perforation in 2 patients (total, 4; 29% of EB). In patients with GB (21), 14 (67%) had mucosal damage; 13 (93%), mild (< Grade III, two esophageal erosions); 1 (7%) IIIa (esophageal ulceration). A statistically significant association between exposure time, younger age or battery size and severity of endoscopic lesions was found in EB location. There were no mortality cases. Acute complications occurred in 57% of EB: infection, 50%; perforation, 29%; pneumomediastinum/stridor, 14%; pneumothorax/subglottic stenosis/hemodynamic instability, 7 vs. 0% GB. Stenosis subsequently developed in 6 (43%) of EB: mild, 4 cases (29%); severe, 2 cases (14%, one resolved after endoscopic dilation; one needed a gastrostomy and esophagocoloplasty). CONCLUSION We verified recent increase in admissions due to battery ingestions and associated complications, despite the availability of an emergency pediatric endoscopy team. The patients with EB had more severe mucosal injury and poorer short/long-term outcomes. Children with GB had milder lesions, although the presence of a GB did not exclude esophageal injury. The availability of actual data from national referral centers will support advocacy efforts among stakeholders, including industry representatives and policy makers, in preventing worldwide button battery injury.

Abstract
Viral infections are frequently present before the clinical manifestation of Guillain-Barre syndrome (GBS). Multiple studies on coronaviruses have shown that these viruses have neurotropic characteristics, and their molecular mimicry can induce inflammatory demyelinating neuropathy. Herein, we describe a case of a GBS in an 85-year-old patient infected with SARS-CoV-2, manifested with acute progressive symmetric ascending quadriparesis, urinary dysautonomia, and dysphagia, who responded well to treatment with intravenous human immunoglobulin.

Developing a social prescribing local system in a European Mediterranean country: a feasibility study to promote active and healthy aging. BMC Health Serv Res 2021; 21:1164. [PMID: 34706718 PMCID: PMC8548849 DOI: 10.1186/s12913-021-07186-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 10/15/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Social Prescribing (SP) is an innovative strategy to respond to the non-clinical health needs of the population. A Social Prescribing Local System (SPLS) can be defined as a set of joined community, health, and social organizations to foster SP-oriented activities. This study aimed to develop and assess the feasibility of an SPLS implemented in a Mediterranean country, to promote health and wellbeing and contribute to active and healthy aging. METHODS A mixed-methods approach was followed, including three sequential components: 1) Cross-sectional online survey targeting health professionals (HP) working in a primary health care cluster, Portugal's southern region; 2) Pilot study implementing an on-the-job training program for HP, designed to meet identified training needs in the survey; 3) Focus group (FG) with the HP who participated in the pilot study, two individual interviews, with an elderly patient and a community provider for assessing the satisfaction with the pilot test. RESULTS Sixty-five HP completed the survey; of these, 13 completed the theoretical part of the on-the-job training program; and six (out of these 13) completed the full program. Five HP participated in the FG, one patient and one community provider were interviewed. The surveyed HP perceived as facilitators to implement SP: an automatic system of notifications to prompt the use of SP, contribute to patient satisfaction, human and community resources' stability. The survey also highlighted barriers to SP implementation: length of appointments, shortage of human resources, data records confidentiality, low patient adherence rates, bureaucratic issues, time constraints, and financial costs. Participants were satisfied with the training. Identified SPLS implementation benefits were grouped into four dimensions (from the qualitative approach): gains for patients' health and wellbeing, support for the health services, sustainability of the community resources, and HP' professional satisfaction. CONCLUSIONS Our study took the first steps towards the implementation of an SPLS. Findings reinforce that training HP in SP and on-the-job training seems feasible. This approach was well received and appears to represent a suitable and sustainable strategy. It can promote professional satisfaction, support health services, contribute to the stability of community resources, improve health and promote active and healthy aging.

Abstract
Abstract
Background
Hospital readmissions of patients with acute coronary syndrome (ACS) are frequent and associated with poor clinical outcomes and increased costs to the healthcare services. Identifying factors that might be associated with hospital readmission is important to support preventive interventions.
Purpose
To identify factors related to hospital readmission of patients with ACS.
Methods
A prospective cohort study. Patients hospitalized with ACS for the first time were included in the study. The outcome, hospital readmission for ACS, was assessed at 30 days, 6 months and 1 year after index discharge. Modifiable cardiovascular risk factors (arterial hypertension, dyslipidemia, diabetes mellitus, smoking, degree of addiction to smoking, use of alcohol, physical inactivity, obesity, stress, depression, excessive daytime sleepiness, obstructive sleep apnea syndrome, hormone replacement) and non-modifiable risk factors (age, race, family history of coronary heart disease) were evaluated as potential predictors of the outcome. Other variables that might have contributed to readmission were also included: marital status, family income, occupation, education, adherence to medication and type of treatment (clinical, percutaneous coronary intervention or coronary artery bypass grafting). The association between hospital readmission and potential predictors was assessed using the Log-Rank test and Cox's simple regression model. Factors whose associations had a p-value of less than 0.20 in the simple regression and other variables of clinical interest were evaluated in a Cox multiple regression model, with p<0.05 considered significant. The study was approved by two Research Ethics Committees.
Results
216 patients were included and the incidence of readmission was 15.7%. Most of the patients were male, white, married, had an income between two and four minimum wages, and a mean age of 60 years. Half of the patients had high adherence to medication. The cardiovascular risk factors identified in most patients were sedentary lifestyle (79.6%), arterial hypertension (63.4%) and obstructive sleep apnea (51.9%). The only independent predictor for readmission was surgical treatment (p=0.026).
Conclusions
Participants had several cardiovascular risk factors and the predictor of hospital readmission was surgical treatment. Identifying the predictive factors of a given population helps nurses in planning and guiding hospital discharge.

Abstract
Abstract
Background
Bisphosphonates (BPs) are widely prescribed drugs that decrease bone fracture risk in osteoporosis patients. Nevertheless, the class has been associated with a plethora of adverse effects, including incidental atrial fibrillation (AF). This epidemiologic link has, however, been met with skepticism by some authors.
Purpose
To perform a meta-analysis aimed at ascertaining the extent to which BPs might increase the odds of AF.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library and Google Scholar, from inception to the first of March, 2021, for randomized controlled trials comparing oral or intravenous BPs with placebo or a no-treatment control, in what concerns AF risk. In order to be included in the quantitative analysis, studies were required to feature a minimum patient follow-up of 6 months. De novo AF diagnoses served as the primary endpoint. Data related to individual BPs were further investigated separately, with respect to this outcome. Study-specific Mantel-Haenszel odds ratios (ORs) were pooled using traditional meta-analytic techniques, under a random-effects model.
Results
42 RCTs, encompassing 52.436 patients (32.071 randomized to BPs), were regarded as eligible for quantitative synthesis. Of note, 2 pooled analyses, one of 4 trials with ibandronate and the other of 6 trials with risedronate, were included. Individual BP representation may be depicted as follows: Alendronate, 23 trials, with 14.599 patients; Risedronate, 7 trials, with 15.350 patients; Zoledronic acid, 7 trials, with 13.059 patients; Ibandronate, 4 trials, with 8.754 patients; and Minedronate, 1 trial, with 674 patients. 748 de novo AF diagnoses were reported, in total. In the main analysis, BPs were not found to be significantly associated with an increase in AF odds (OR 1.10, 95% CI 0.95–1.28, P 0.21, i2 0%). As for individual BPs, Alendronate (OR 1.09, 95% CI 0.82–1.45, P 0.55, i2 0%), Risedronate (OR 0.81, 95% CI 0.35–1.86, P 0.61, i2 31%), Ibandronate (OR 0.89, 95% CI 0.52–1.52, P 0.67) and Minedronate (0 AF events reported, both in the active and in the control group) were also not shown to meaningfully enhance AF risk. On the contrary, Zoledronic acid utilization was associated with a significant, though small, increase in new AF cases (OR 1.29, 95% CI 1.01–1.64, P 0.04, i2 0%).
Conclusion
The professed BP-driven increase in AF odds is not apparent in a fairly populated randomized setting. In fact, a barely significant increment in AF risk seems only to occur with the most potent BP (Zoledronic acid). Therefore, AF development concerns should not refrain doctors from prescribing this highly effective pharmacological class.

Abstract
Abstract
Background
Antiplatelet and anticoagulants are one of the mainstay treatment of acute coronary syndrome (ACS), however they are associated with a significant increase of bleeding risk. While anaemia is a recognized predictor of adverse outcomes, it is unknown if a variation of haemoglobin (HB) levels, even without associated anaemia, has the same impact.
Purpose
The aim of this study was to determine the prognostic impact of HB variation after percutaneous coronary intervention (PCI) in ACS patients.
Methods
Retrospective analysis of 822 consecutive patients admitted due to ACS and treated with PCI, in a single coronary intensive care unit. Delta HB – ΔHB – (HB at admission – HB 24 hours after PCI) was calculated. Clinical variables and therapeutic strategies were examined. The primary endpoint analysed during follow-up was all-cause mortality. Possible predictors for all-cause mortality were assessed by Cox regression models. When statistically significant values were found in univariate analysis, multivariate analysis was used to determine whether ΔHB was independent from other known factors in predicting the outcome.
Results
In the studied sample, 75.4% were male. Mean age was 66.4±13.1. ST-elevation myocardial infarction (STEMI) occurred in 45.5%, non-ST segment elevation myocardial infarction in 42.6% and unstable angina in 11 9% of the studied population. Moderate to severe systolic dysfunction was present in 23.5% of the cases. Regarding comorbidities and past medical history, 76% had hypertension (HTN), 30.3% diabetes, 16.4% chronic kidney disease (CKD), 62.2% dyslipidaemia and 10.5% heart failure (HF). Mean HB at admission was 13.8±1.8 g/dL, mean HB after PCI was 12.9±1.9 g/dL and mean ΔHB was 0.9±1.1 g/dL. The mean follow-up was 51.6±30.6 months. In univariate analysis, ΔHB was significantly associated with all-cause mortality (HR 1.15 per 1 g/dL loss, 95% CI 1.01–1.30, p=0.04), as was HB at admission, HB after PCI, age, sex, diabetes, HTN, dyslipidaemia, CKD and moderate to severe systolic dysfunction. In multivariate analysis, ΔHB remained significantly associated with the endpoint and gained even more statistical power (HR 1.25, 95% CI 1.10–1.43, p<0.01). HB at admission and after PCI, age, CKD and moderate to severe systolic dysfunction were also independent predictors of this outcome.
Conclusions
In our study, irrespective of the admission and discharge HB, ΔHB was associated with more adverse outcomes in patients submitted to PCI. Hence, even patients with a normal HB after PCI have a worse long-term prognosis if a negative variation of HB occurs. This highlights the importance of identifying and optimising all the correctable factors that might lead to an increased bleeding risk.

Abstract
Abstract
Background
Obesity and overweight are a worldwide public health problem, and physical exercise is an important intervention to reduce these high rates. Supervised exercise programs have significant impacts on the prevalence of obesity in adolescentes and the nurses should guide on the importance of physical activity.
Purpose
To evaluate the effect of an exercise program on the profile of obesity and overweight in adolescents.
Methods
Quasi-experimental study based on TREND guidelines. Performed with 72 adolescents, who underwent a physical activity program supervised (aerobic and resistance physical exercises) by a health professional 5 times a week, each session lasting from 50 to 60 minutes. The population consisted of all obese and overweight adolescents, aged between 14 and 18 years, who were authorized by the doctor to perform physical activity, and who did not have physical mobility problems and/or cognitive alterations. Adolescents with an anthropometric index greater than or equal to the z +1 score, and waist circumference greater than the 90th percentile, and/or skinfolds greater than the 90th percentile were considered obese or overweight. Adolescents who did not perform outcome assessments before and after the intervention, or those who did not attend physical exercise sessions for a week were excluded. The primary outcomes were anthropometric measurements (body mass index, tricipital and subscapular skinfolds, estimated body fat percentage, brachial perimeter, arm fat area, waist and neck circumference measurement), while secondary outcomes were lipid profile, capillary glycemia and blood pressure. Outcomes were assessed before and the day after the program ended. The effect of the program in relation to the outcomes was analyzed using appropriate statistical tests, with p<0.05 being considered significant.
Results
A total 520 adolescents were assessed for eligibility; of these, 129 were considered eligible and 124 agreed to participate in the study, but 20 gave up participating. Therefore, 104 started the intervention and 32 adolescents were excluded over time, as they did not show up for a week in the exercise program, which totaled 72 adolescents for analysis. A significant improvement was observed in all primary outcomes analyzed (p<0.001) and in most secondary outcomes (capillary blood glucose, p=0.0001; triglycerides, p=0.0001; systolic blood pressure, p=0.005) after 12 weeks of the supervised physical exercise program.
Conclusion
The supervised physical exercise program showed a significant reduction in anthropometric measurements, as well as in glycemic, triglyceride and blood pressure levels. To prove the effect of physical exercise on adolescents may impact public and educational policy measures and the incorporation of this practice in adolescents' school life.

Subsegmental pulmonary embolism: yet another case for being a medical conservative. Eur Heart J 2021.

Abstract
Abstract
Background
The advent of multi-detector computed tomographic pulmonary angiography has allowed better assessment of the peripheral pulmonary arteries, thereby increasing the incidence of pulmonary embolism (PE). Even though most patients with PE are treated with anticoagulation, its value in the subsegmental setting (SSPE) has not yet been confirmed.
Purpose
To perform a meta-analysis aimed at ascertaining the extent to which anticoagulation results in a net positive effect in patients with SSPE.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library and Google Scholar, from inception to March 2021, for controlled studies addressing the effect of anticoagulation on SSPE patients. Specifically, venous thromboembolism (VTE) recurrence served as the primary efficacy endpoint, whereas clinically significant bleeding represented the primary safety outcome. Furthermore, major bleeding, PE-related and all-cause mortality were also studied, as secondary endpoints. All anticoagulation strategies, namely oral or parenteral, met inclusion criteria. Study-specific odds ratios (ORs) were pooled, under a random-effects model.
Results
1 cross-sectional, 8 retrospective and 4 prospective non-randomized studies, encompassing 82, 641 and 157 patients, respectively, were regarded as eligible for quantitative evaluation. 667 patients (75.8%) were allocated to the anticoagulation arm. The absolute number of events for each outcome may be reported as follows: primary efficacy endpoint, 5; primary safety endpoint, 60; major bleeding, 38; PE-related mortality, 0; all-cause mortality, 25. 7 studies reported their respective outcomes under a prespecified 3-month follow-up period, while only 1 featured cancer patients as its entire sample. As for the primary efficacy endpoint, and despite the surprising adjudication of all its 5 events to the anticoagulated patients, their relative overrepresentation (371 vs. 143 patients) stemmed a non-significant tendency towards a decrease in VTE recurrence in this arm (OR 0.59, 95% CI 0.09–3.81, P 0.58, i2 0%). On the other hand, anticoagulation was associated with a significant increase in clinically significant hemorrhages (OR 2.89, 95% CI 1.07–7.80, P 0.04, i2 0%) and a non-significant propensity towards an increment in major bleeding (OR 2.44, 95% CI 0.79–7.59, P 0.12, i2 0%). Lastly, and even though no events of PE-related mortality were reported, anticoagulation was linked with a meaningful reduction in all-cause mortality (OR 0.31, 95% CI 0.11–0.82, P 0.02, i2 0%).
Conclusion
Currently available evidence underpins marginal efficacy and safety concerns regarding the use of anticoagulation in SSPE patients, who are expected to experience very low to none PE-related mortality. The association of anticoagulation with lower all-cause death may be attributable to selection bias. Randomized controlled trials are, however, still needed to fully validate this hypothesis.

Abstract
Atrial septal defect (ASD) closure is indicated in the presence of a significant left-to-right shunt. In the case of an interrupted inferior vena cava (IVC), the standard percutaneous approach can be troublesome. The authors report a case of a 55-year-old female patient with an ostium secundum ASD with a significant left-to-right shunt at rest (Qp/Qs, 1.6). The cardiac computed tomography scan showed an interrupted IVC above the renal veins. To our knowledge, this is the first case in the literature where the transbasilic peripheral vein approach for ASD closure was used.

Abstract
Nutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football's physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.

Abstract
Abstract
Background
Currently, the evaluation of biomarkers HER-2 and ER is critical for targeting therapy for breast cancer and is performed by experienced pathologists, which takes time and causes a certain interobserver variability. The use of histological slide scanners coupled with the application of software for immunoexpression quantification can be profitable in pathological laboratories routine. This study aims to compare the quantification of HER-2 and ER immunoexpression employing automatic algorithms, using as standard the evaluation performed by a pathologist.
Methods
From the archive since 2016 to 2018 were retrieved 75 immunostained slides for HER-2 and 76 immunostained slides for ER with invasive breast carcinoma diagnosis. The slides were scanned in Aperio CS2 and the immunostaining signal was quantified in Aperio Imagescope using a membrane and nuclear algorithm, respectively. The concordance between the scores obtained and the previous assessment was calculated by Cohen’s Kappa coefficient as well as the sensitivity and specificity for each algorithm.
Results
Both algorithms showed an almost perfect concordance with the conventional method (k = 0.94 for HER-2; k = 0.92 for ER). Digital evaluations presented a sensitivity of 100% for both biomarkers, and a specificity of 100% for HER-2 and 80% for ER.
Conclusions
This assay showed that applying signal quantification software for HER-2 and ER in digitized slides is accurate, as these tools have potential to be implemented in laboratory routine. However, it will be necessary to increase the sample to obtain more reliable values and extend this study to the PR and Ki67 biomarkers since both carry prognostic and predictive information as well.

Abstract
OBJECTIVES To determine the predictive value of early transcranial color-coded sonography (TCCS) for intracranial hemorrhage (ICH) in patients with large artery occlusion (LAO) stroke of carotid circulation, who were submitted to endovascular therapy (EVT) with successful reperfusion. MATERIALS AND METHODS Retrospective study evaluating a cohort of consecutive stroke patients with LAO of the carotid circulation that were recanalyzed with EVT. We measured angle-corrected peak systolic velocities, end-diastolic velocities and mean flow velocities (PSV, EDV and MFV) of the symptomatic and asymptomatic middle cerebral artery (MCA). The ratio between MFV of the symptomatic MCA and MFV of the asymptomatic MCA (MCA-Ra) was calculated. Parenchymal hematoma in the 24 hours control CT was considered as ICH. Univariate associations and multivariate analyses were used to identify early independent predictors for ICH among TCCS findings. RESULTS We included 234 patients, mean age 72.5 (SD 12.6) years, 52.1% male. The mean time between recanalization and TCCS was 12.3 hours (range 3-22). Patients who developed postinterventional ICH showed a higher MCA-Ra (1.02 ± 0.26 vs 1.16 ± 0,21, p = 0.036). In multivariate analysis, only higher MCA-Ra remained independently associated with postinterventional ICH (OR: 6.778, 95%CI: 1.152-39.892, p = 0.034). A value of MCA-Ra ≥ 1,05 was associated with ICH, showing a sensitivity of 81.3% and a specificity of 65.9%; the AUC based of the ROC analysis was 0.688 (95% CI 0.570-0.806). CONCLUSION TCCS performed within the first 24 hours after stroke onset can help to predict hemorrhagic transformation in patients with LAO.

Abstract
INTRODUCTION Epilepsy is more prevalent in men but Genetic Generalized Epilepsies (GGE) seem to be more common in women. A predominant maternal inheritance has been previously described in GGE. Our objective was to determine sex and inheritance patterns in a GGE population compared to mesial temporal lobe epilepsy with hippocampal sclerosis (MTLEHS). METHODS We performed a prospective observational study including adult GGE and MTLEHS patients followed up at a tertiary epilepsy center from January 2016 to December 2019. Patients' familial history was obtained by a detailed questionnaire. Clinical and demographic data was retrieved from clinical notes. RESULTS A cohort of 641 patients, 403 with GGE and 238 with MTLEHS, was analyzed. GGE was more common in women than MTLEHS (58.8% vs 44.5%, OR=1.63, p = 0.004). Compared to MTLEHS patients, more GGE patients had familial history of epilepsy (45.4% vs 25.2%; p<0.001). The GGE group had a higher percentage of female relatives with epilepsy (55% vs 37%; p = 0.006). The prevalence of maternal inheritance was not different between GGE and MTLEHS groups (62.9% vs 57.7%; p = 0.596). Photosensitivity was more common in females than in males (44.7% vs 34.3%, p = 0.036). CONCLUSION There is a female preponderance in GGE when compared to MTLEHS, as both GGE patients and their affected relatives are more frequently women. The prevalence of maternal inheritance was not higher in GGE than in MTLEHS.

Abstract
Summary Background. Drug hypersensitivity in children impacts the quality of life of the patients and their caregivers. The parent-reported drug hypersensitivity quality of life questionnaire (P-DrHy-Q), the first disease-specific quality-of-life questionnaire for caregivers who have children with drug hypersensitivity, was recently developed. The aim of this study was to assess the validity and reliability of the portuguese version of the P-DrHy-Q. Methods. A translation of the Parent-reported Drug Hypersensitivity Quality of Life Questionnaire (P-DrHy-Q) to the Portuguese population was performed, assessing its applicability in 74 caregivers from two allergy departments. The analyses included internal consistency (Cronbach's alpha) and test-retest reliability: 14 caregivers completed the P-DrHy-Q without any intervention one week after answering the first questionnaire. Results. The 12-item scale assessed the mental health and social activity. The internal consistency of the scale was good (Cronbach's alpha = 0.884) and the test-retest associations were excelent (Intra-class correlation coefficient = 0.985; p less than 0.001). The mean value of the questionnaire was (37.01 SD; 18.57) with Mental Health being more affected than Social Activity. Employed caregivers had a significant higher score (p less than 0.001). No other factor was statistically significant. Conclusions. The Portuguese version of the P-DrHy-Q is valid for evaluating quality of life impairment in Portuguese caregivers of children with drug hypersensitivity. Its application might be relevant for future research and provide clinicians and researchers with a tool to define which psychosocial support is required to provide more comprehensive care in drug hypersensitivity.

Abstract
Summary Background. Acute urticaria is a common condition in the pediatric emergency department (ED) and no data is available in Portugal. Objective. We aimed to characterize the prevalence, etiology and management of acute urticaria in children presenting at an ED of a portuguese central hospital and report the follow-up investigation when drug or food allergy was suspected.Methods. Retrospective study of clinical records from children admitted to the ED with acute urticaria during one year period. Results. 250 children were included, mean age of 7.4 ± 4.9 years (0-17 years). The most frequently suspected etiological factors were infections (22%), foods (12%), insect bites (9%) and drugs (8%), of which, upper respiratory tract infections, seafood and β-lactam antibiotics were the most frequent. In 44% of cases, the etiology of urticaria was not determined. After ED discharge, of the 50 patients with suggestive drug or food allergy, only 48% were sent to allergological workup and the allergy confirmed in 6 of them (2.4% of the 250 children). Conclusions. These data suggest that allergy is not the main trigger of acute urticaria in ED children, but when suspected, reference to an allergy department to complete allergological workup was insufficient.

Chronic kidney disease in acute coronary syndromes: real world data of long-term outcomes. Future Cardiol 2021; 17:1359-1369.

Abstract
Aim: Patients with chronic kidney disease (CKD) are at increased cardiovascular risk. Methods: Patients with acute coronary syndrome were retrospectively allocated to three groups (stage 3A, stage 3B or stage 4) based on the Kidney Disease Improving Global Outcomes classification formulas: the CKD Epidemiology Collaboration (CKD-EPI; N = 401) and the modification of diet in renal disease (n = 355). The primary end point was all-cause mortality (median follow-up time, 32 months [15-70]). Results: Study results showed decreased median survival was associated with poor renal function for both the CKD-EPI (78 vs 61 vs 40 months, p = 0.014) and modification of diet in renal disease groups (68 vs 57 vs 32 months, p = 0.006). After adjustment, age (OR: 1.07; 95% CI: 1.01-1.14) and pulmonary artery systolic pressure (OR: 1.08; 95% CI: 1.03-1.14), but not estimated glomerular filtration rate, were associated with decreased survival. Conclusion: Study results suggest that poor outcomes after an acute coronary syndrome were associated with comorbidities rather than estimated glomerular filtration rate level.
