Physical and Physiological Demands of Amateur Portuguese Field and Assistant Football Referees. Sports (Basel) 2024; 12:133. [PMID: 38787002 PMCID: PMC11126070 DOI: 10.3390/sports12050133] [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: 04/11/2024] [Revised: 05/04/2024] [Accepted: 05/13/2024] [Indexed: 05/25/2024] Open
Abstract
Referees are crucial elements in football, and they must meet the physical and physiological demands each match poses to them. The aim is to analyse the physical and physiological demands of amateur referees in games at the regional level (4th division), examining the differences between the first and second halves and between assistant (age: 25.10 ± 4.97) and main referees (age: 25.65 ± 5.12). A total of 29 matches were analysed with GPS devices, and internal and external load metrics were analysed. Overall, main referees, due to their central role in game management, showed higher levels of physical and physiological load than assistant referees, with more high-intensity activities, greater distance covered and higher heart rate. The results also revealed that there were no differences between the halves for total distance covered for either the main or assistant referees. However, the main referees covered a greater distance in high-intensity running during the first half (p = 0.05; d = 0.389). These findings emphasise the importance of tailored training protocols to enhance performance and reduce fatigue-related errors, highlighting the significance of endurance, high-intensity running ability, and strategies to manage transient fatigue in referee preparation.

Evidence of plastics contamination and sewage-derived residues in a Brazilian Hope Spot for conservation of marine biodiversity - Cagarras Islands and surrounding waters. MARINE POLLUTION BULLETIN 2024; 203:116407. [PMID: 38701605 DOI: 10.1016/j.marpolbul.2024.116407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 04/08/2024] [Accepted: 04/19/2024] [Indexed: 05/05/2024]
Abstract
Cagarras Islands Archipelago, a no-take MPA in Southeast Brazil, was designated as Natural Monument (MONA Cagarras) and, more recently, recognized as Hope Spot for biodiversity conservation. This study aimed to assess plastic contamination by analyzing marine litter and microplastics in MONA Cagarras and surrounding waters. Marine litter (34.12 kg) was caught by artisanal fishermen in MONA Cagarras proximities, and plastics represented ∼79 %. Personal hygiene items and strains of hair were found, suggesting sewage-derived contamination from Ipanema SSO. Microplastics were detected in MONA Cagarras surface waters. Fragments and black particle were the most frequently found microplastic shape and color, respectively. μ-FTIR analysis identified, in descending order of occurrence, polystyrene-PS, polyethylene-PE, polyvinyl chloride-PVC, polypropylene-P, and polyamide-PA. Our integrated results of macro and microplastic contamination highlight an issue of effective conservation and health of marine biodiversity in MONA Cagarras and surrounding waters and a concern for better management of Brazilian MPAs.

Methodology and Experimental Protocol for Studying Learning and Motor Control in Neuromuscular Structures in Pilates. Healthcare (Basel) 2024; 12:229. [PMID: 38255116 PMCID: PMC10815589 DOI: 10.3390/healthcare12020229] [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: 11/29/2023] [Revised: 12/28/2023] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
The benefits of Pilates have been extensively researched for their impact on muscular, psychological, and cardiac health, as well as body composition, among other aspects. This study aims to investigate the influence of the Pilates method on the learning process, motor control, and neuromuscular trunk stabilization, specifically in both experienced and inexperienced practitioners. This semi-randomized controlled trial compares the level of experience among 36 Pilates practitioners in terms of motor control and learning of two Pilates-based skills: standing plank and side crisscross. Data will be collected using various assessment methods, including abdominal wall muscle ultrasound (AWMUS), shear wave elastography (SWE), gaze behavior (GA) assessment, electroencephalography (EEG), and video motion. Significant intra- and inter-individual variations are expected, due to the diverse morphological and psychomotor profiles in the sample. The adoption of both linear and non-linear analyses will provide a comprehensive evaluation of how neuromuscular structures evolve over time and space, offering both quantitative and qualitative insights. Non-linear analysis is expected to reveal higher entropy in the expert group compared to non-experts, signifying greater complexity in their motor control. In terms of stability, experts are likely to exhibit higher Lyapunov exponent values, indicating enhanced stability and coordination, along with lower Hurst exponent values. In elastography, experienced practitioners are expected to display higher transversus abdominis (TrA) muscle elasticity, due to their proficiency. Concerning GA, non-experts are expected to demonstrate more saccades, focus on more Areas of Interest (AOIs), and shorter fixation times, as experts are presumed to have more efficient gaze control. In EEG, we anticipate higher theta wave values in the non-expert group compared to the expert group. These expectations draw from similar studies in elastography and correlated research in eye tracking and EEG. They are consistent with the principles of the Pilates Method and other scientific knowledge in related techniques.

Movement variability in Pilates: a scoping review. Front Psychol 2023; 14:1195055. [PMID: 37780172 PMCID: PMC10540319 DOI: 10.3389/fpsyg.2023.1195055] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 08/21/2023] [Indexed: 10/03/2023] Open
Abstract
Objective This scoping review aimed to identify studies that analyzed movement variability in Pilates. Following a systematic approach to mapping evidence on this topic would highlight concepts, theories, sources, and knowledge gaps in this area. Methods This review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) criteria for the selection, reading, and analysis of studies in this area. We searched five literature databases (Web of Science, SCOPUS, library catalog of the Faculty of Sport and Physical Education of the University of Coimbra-EBSCO Discovery Services, MEDLINE, and Google Scholar). Eligible articles contained the word "Pilates," and the human movement variability was analyzed. Any type of study (except reviews) could be eligible and must have been published between 1 January 2002 and 30 November 2022, in Portuguese, Spanish, French, or English. Results Our search identified five eligible entries. Only one study used the Pilates method in its intervention, pointing to a more significant variability of hip-knee coordination, suggesting more diversified coordination patterns, and maintaining the variability of the angular position of the joint. Conclusion Very few studies have examined movement variability in Pilates, and only one applied an ecological framework.

Hypersensitivity to Non-Steroidal Anti-Inflammatory Drugs on a pediatric Portuguese cohort. Eur Ann Allergy Clin Immunol 2023. [PMID: 37249059 DOI: 10.23822/eurannaci.1764-1489.299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/31/2023]
Abstract
Summary Background. Non-steroidal anti-inflammatory drugs (NSAID)/analgesics (paracetamol) are among the most common causes of drug hypersensitivity reactions in children, with a reported prevalence of around 0.3% in the pediatric population. Paracetamol and ibuprofen are the most commonly reported culprits in the pediatric population. Our objective was to describe the allergy workup to NSAID/paracetamol of a pediatric population monitored in an allergy outpatient clinic. Methods. Retrospective observational study by consulting the medical records of patients evaluated in a pediatric outpatient clinic with history of NSAID/paracetamol, between January 2016 to August 2022. Results. A total of 43 patients have been evaluated for NSAID/paracetamol suspected allergy: 53.5% females, mean age of 9.8 ± 5.1 years, 47.7% atopic. The drugs reported as culprits were: ibuprofen (75.6%), paracetamol (17.8%), metamizole (4.4%) and naproxen (2.2%) and clinical manifestations were mainly urticaria/angioedema and maculopapular exanthema. Skin tests were performed in 7 patients: paracetamol (n = 5) and metamizole (n = 2), which were all negative. Fourty-six drug provocation tests were performed: 28 with the culprit drug and 18 with an alternative one; only 2 were positive (ibuprofen - culprit NSAID group): one immediate periorbital angioedema and one delayed lip edema with oropharyngeal tightness. Conclusions. The investigation of allergy to NSAID/paracetamol in children remains a challenge. In our population, ibuprofen was the most common NSAID reported. There were only 2 (4.3%) mild reactions on DPT. We could allow the use of the culprit NSAID/analgesic in 11 patients and an alternative one in 9 patients. This study highlights the importance of DPT in children for a correct diagnosis of NSAID hypersensitivity and selection of an alternative drug.

CURB-65 and Long-Term Mortality of Community-Acquired Pneumonia: A Retrospective Study on Hospitalized Patients. Cureus 2023; 15:e36052. [PMID: 37056522 PMCID: PMC10089637 DOI: 10.7759/cureus.36052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/12/2023] [Indexed: 03/13/2023] Open
Abstract
Background Community-acquired pneumonia remains a significant factor in global mortality. Several clinical scoring models are used for predicting pneumonia severity and mortality, aiding in the clinical decision relative to the therapeutic approach, including the CURB-65 score. However, currently, no models exist to identify high-risk patients relative to long-term prognosis when recent evidence reveals a significantly higher mortality rate in the first year after community-acquired pneumonia (CAP) hospitalization. Purpose of the study The purpose of this study is to evaluate the application of the CURB-65 scoring model in our population and examine its potential to predict prognosis and subsequent mortality 6 months after hospitalization. Other potential factors influencing mortality during and after hospitalization were characterized: patient demographics, nosocomial infections, readmissions, and identified pathogens. Study design We conducted a retrospective observational study, enrolling 130 patients admitted with a diagnosis of CAP in the department of internal medicine of Centro Hospitalar Universitário Cova da Beira between January and December of 2018. Consultation of electronic medical records was used to calculate the CURB-65 score on admission at the first hospitalization by CAP, categorizing patients into five risk groups. Mortality and readmission were evaluated after 30, 90, and 180 days. Key results High-risk patients (CURB>2) accounted for 96.9% of our study population. Inpatient mortality of 13%, increasing to 21.5% after six months, was similar to previous studies and was correlated to the CURB-65 score on admission. A microbiologic agent was identified in 37% of cases, with 53% isolates of Streptococcus (S.) pneumoniae. Conclusions Identifying high-risk patients is important for more individualized healthcare and management. The CURB-65 score, only validated for a short-term (30 days) prediction, demonstrates a potential to also predict mortality and rehospitalization in the six-month period after hospitalization, as supported by our findings and previous studies.

Q Fever Spondylodiscitis: A Rare Manifestation of a Challenging Disease. Eur J Case Rep Intern Med 2022; 9:003703. [PMID: 36632533 PMCID: PMC9829017 DOI: 10.12890/2022_003703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022] Open
Abstract
Coxiella burnetii causes Q fever, which is found worldwide and can be acute or chronic. This case report describes a 72-year-old man whose bilateral lower limb pain revealed a paravertebral abscess at L2-L3 due to Q fever spondylodiscitis. Surgical drainage of the abscess was performed and medical treatment is ongoing. Q fever is endemic in Portugal and transmitted by inhalation of aerosols containing spores from infected animals (cattle, goats and sheep) or by ingesting cottage cheese or unpasteurized milk. It has an incubation period of 2-3 weeks and 60% of patients are asymptomatic with only 2% needing hospitalization. Primary infection can manifest in any organ and most cases are self-limiting (self-limited febrile illness, atypical pneumonia or acute hepatitis). Less than 1% of cases evolve to chronic disease, presenting as osteomyelitis or endocarditis. Chronic disease poses a diagnostic challenge and spondylodiscitis has an insidious evolution. Diagnosis requires microbiological and clinical confirmation. Serological and polymerase chain reaction tests are used for diagnosis. Acute disease is usually treated with doxycycline for 3 weeks to avoid evolution to chronic disease. Chronic disease requires 18-24 months of doxycycline with hydroxychloroquine. Acute disease can recur so follow-up is essential as chronic Q fever can result in morbidity and mortality. In Portugal Q fever is a notifiable disease due to the epidemiological risk. LEARNING POINTS Coxiella burnetii spondylodiscitis is rare so clinicians should be aware of it.The diagnosis of Q fever is challenging, especially chronic disease that presents with endocarditis, osteomyelitis or spondylodiscitis.Spondylodiscitis treatment is particularly challenging and may need neurosurgical intervention.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
Abstract
Background
The long-term survival rates of myocardial infarction with non-obstructive coronary arteries (MINOCA) patients is lower than in the general population. Nevertheless, there are conflicting results regarding the prognosis of MINOCA patients in comparison to myocardial infarction with obstructive coronary artery disease (MI-CAD) patients.
Purpose
The aim of this study was to assess the long-term all-cause mortality of MINOCA patients and compare it to MI-CAD patients.
Methods
Retrospective analysis of 2443 consecutively admitted patients for acute myocardial infarction (AMI), in a single coronary intensive care unit. Only patients with 5 years of follow-up and those who died before the 5-year mark were considered. Patients were divided into two groups according to the presence or absence of obstructive coronary artery disease on angiography (≥50% stenosis). Demographic characteristics, symptoms at presentation, past medical history, laboratory characteristics and medication at discharge were compared using the Mann-Whitney U or χ2 test (according to variable type) to ensure comparability between groups. Five-year all-cause mortality was the target endpoint. Five-year survival was modelled through the Cox proportional hazard regression model. The variable of interest (MINOCA vs MI-CAD) and possible confounders that displayed statistically significant differences in the initial demographic analysis were included in univariable Cox regressions, and those with statistically significant associations were included in a multivariable model. Those that displayed non-significant associations in the multivariable model were subsequently removed until we were left with significant associations only, giving us an adjusted hazard ratio.
Results
Comparison between groups is presented in table 1. MINOCA patients were younger and more often women. They were less likely to have smoking habits, diabetes, or a previous history of AMI. They had a lower Killip class, as well as lower troponin I, serum creatinine and low-density lipoprotein cholesterol at admission. On the other hand, they had higher left ventricular ejection fractions. They were also less likely to have beta-blockers or aspirin prescribed at discharge.
All-cause mortality at 5 years was 13.1% among MINOCA patients and 28.3% among MI-CAD patients, with an unadjusted hazard ratio (HR) of 0.421 (95% CI 0.322–0.550), p<0.001. Adjusting for known confounders, the HR was 0.461 (95% CI 0.261–0.816), p=0.008.
Conclusions
Compared with MI-CAD patients, those with MINOCA were slightly younger and had fewer comorbidities. In spite of having a worse long-term prognosis when compared to the general population, MINOCA patients have a significantly higher 5-year survival rate than MI-CAD patients, even after adjustment of confounding factors.

Abstract
Abstract
Background
In the PARADIGM-HF trial, sacubitril/valsartan (SV) was shown to be superior to enalapril in reducing hospitalizations for worsening heart failure (HF), cardiovascular mortality, and all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). The 2021 ESC Guidelines recommends SV as a replacement for angiotensin-converting-enzyme inhibitors to reduce the risk of HF hospitalization and death. There is little information regarding the effects of SV according to atrial fibrillation (AF) status.
Purpose
The aim of this study was to compare the effects of maximum dose SV regarding symptomatic improvement, change in natriuretic peptides levels (NP) and left ventricular ejection fraction (LVEF) in patients with HFrEF with and without AF.
Methods
Retrospective analysis of 137 patients with HFrEF on maximum dose SV (97/103mg twice daily). Patients were divided into two groups according to AF status. Age, gender, relevant comorbidities, usual medication, baseline symptomatic status, NP levels and LVEF were assessed using the Mann-Whitney U or χ2 test (according to variable type) to ensure comparability between groups. Variation in NYHA class, NP levels and LVEF between baseline and 6-month follow-up was evaluated and compared between groups.
Results
Comparison between groups is presented in Table 1. In our studied population, ischemic aetiology was more common in the sinus rhythm group (49.5% vs 30.4%; p 0.034). There were no significant differences between groups regarding age, gender, hypertension, diabetes, and beta-blocker and mineralocorticoid receptor antagonist usage. At baseline, the AF group had higher NT-proBNP levels [median 1421 mg/dL (IQR 743–3087) vs 467 mg/dL (IQR 140–797); p<0.001]. There were no significant differences regarding baseline NYHA class or LVEF. After 6 months of follow-up, reductions in NYHA class [−1 (IQR −2, −1) for AF; −1 (IQR −1, 0) for SR; p=0.437] and NT-proBNP levels [−358 mg/dL (IQR −2275, −47) for AF; −162 mg/dL (IQR −364, 27) for SR; p=0.156], as well as LVEF improvement [11% (IQR 3–15) for AF; 12% (IQR 7–21) for SR; p=0.201], displayed no statistically significant differences between the two groups.
Conclusions
Our study shows that the beneficial effects of SV on symptomatic status, NP levels and LVEF were not compromised by the presence of AF at baseline.

Introduction
Mouse neonates at postnatal day 1 (P1) are able to regenerate their hearts after myocardial infarction (MI) by reactivating cardiomyocyte proliferation and neovascularization, with little to no fibrosis. However, this process is transient and 7 day-old animals develop a reparative response as observed in adults [1]. After MI, these animals undergo permanent loss of myocardial tissue that is replaced by a rigid fibrotic scar to avoid organ rupture, having devastating consequences for heart function. Although the role of cardiac fibroblasts (CF) - the main orchestrators of fibrosis – in adults is well-documented, no study has unveiled the role of CF during neonatal regeneration. Recent work from our group showed that at least a subset of neonatal CF is able to provide pro-regenerative cues to cardiomyocytes, pointing to a beneficial role of CF in MI resolution.
Purpose
The ultimate goal of our research is to unravel CF-mediated mechanisms that confer regenerative potential to the neonate and re-activate these processes in the adult.
Methods
Mouse ventricles from E16, P1, P3 and P7 mice were subjected to targeted RNA-sequencing. To unveil non-myocyte cell dynamics in the first week after injury in regenerative (P1) hearts, myocardial infarction (MI) was induced by permanent ligation of the left descending coronary artery. To specifically assess the impact of CF in heart regeneration, a Tcf21iCre knock-in mouse line, carrying the diphtheria toxin receptor, was generated, rendering Tcf21+ CF - the majority of CF in the heart - susceptible to diphtheria toxin.
Results
Transcriptional profiling around birth highlighted severe extracellular matrix (ECM) changes from regenerative (P1) to reparative stages (P7). Coherently, from P1 to P7 CF were found to populate the myocardium and undergo a phenotypic shift that explained the transcriptional alterations observed for ECM-encoding genes, indicating a role of CF in the regeneration to repair transition. After MI at P1, CF were found to be readily and transiently recruited to the ischemic site, peaking at day 5 post-MI and returning to basal levels at day 7, a period in which cardiomyocyte proliferation and neovascularization were up-regulated. Of note, no evidence was found of fibrotic tissue or myofibroblasts from 7 days post-MI onwards. Contrarily, MI at P7 resulted permanent loss of cardiomyocytes, impaired neovascularization and formation of aberrant fibrosis as a result from exuberant and persistent fibroblast recruitment and activation. To evaluate the functional impact of fibroblast ablation during the regenerative response, ablation of Tcf21+ CF was performed after MI at P1. CF removal resulted impaired cardiac cell proliferation, indicating that CF recruited after MI are essential for effective neonatal regeneration.
Conclusion
After birth, CF undergo a switch from a regenerative to reparative phenotype that contributes to the loss of regenerative capacity after birth.

Abstract
Introduction Bariatric surgery is considered an effective treatment against obesity. Psychiatric illness is relatively common in patients who have undergone bariatric surgery. Over one-third of these patients are prescribed psychotropic drugs, particularly antidepressants. Unlike medications for diabetes, hypertension or hyperlipidemia, which are generally reduced and at times discontinued, postsurgery psychotropic use is only slightly reduced. The surgical intervention and the subsequent weight loss can affect several pharmacokinetic parameters, leading to a possible need of dosing adjustment. Objectives To review the influence of bariatric surgery on the use and pharmacokinetics of psychotropic drugs. Methods Non-systematic review of literature through search on PubMed/MEDLINE for publications from 2011 to 2021, following the terms psychotropic and bariatric surgery. Textbooks were consulted. Results It is difficult to predict how psychotropics will be affected by bariatric surgery because of interindividual differences and limited data. Malabsorptive surgical procedures have a relatively greater potential to alter drug exposure. Medication disintegration, dissolution, absorption, metabolism and excretion have been found to be altered in postbariatric patients. Antidepressants are the best studied psychotropics in the bariatric population and their absorption is reduced. The risk of gastric bleeds with bariatric surgery will probably be increased by serotoninergic antidepressants. Antipsychotics and mood stabilisers are not well studied in these patients. Depot antipsychotics avoid the risk of reduced absorption after surgery. Lithium use requires particular close monitoring. Conclusions
Close treatment monitoring and the ongoing monitoring of symptoms are needed after bariatric surgery. Many patients may not require significant changes to drug treatment after surgery. Disclosure No significant relationships.

Abstract
Introduction Depression as a public health concern highlights the importance of prevention. The nature of the disease is complex, linked to numerous biopsychosocial factors. However, it was found that healthiest lifestyle reduced 67% the risk of depressive symptoms. Objectives To review evidence on how exercise, diet, and smoking impact on the risk of depression. Methods Non-systematic review of literature through search on PubMed/MEDLINE following the terms “Lifestyles”,“risk” and “depression”. Results Several studies have shown that exercise reduces the incidence of depressive symptoms and major depressive disorder regardless of intensity, geographic region, age, gender, or follow-up period. Smoking significantly increases the risk of depression, including the ones exposed to second-hand smoking and pregnant women in which prenatal smoking was associated with a three-fold increased risk of postpartum depression. The Mediterranean diet rich in complex carbohydrates, omega-3 fatty acids, B-group vitamins and several amino acids have shown a negative association with the incidence of depression. A high frequency of breakfast consumption, an increased intake of fruits, vegetables, and some specific nutrients (zinc, iron, magnesium, vitamins, and folate) was also inversely correlated with prevalence of depressive symptoms. On the other hand, western dietary patterns, with sweetened beverages, processed food, and foods rich in saturated fatty acids, have been linked to an increased risk. Skipping meals and snacking on unhealthy food also contributes to depressive symptoms. Conclusions Relatively modest changes in population diet, tobacco consumption and levels of exercise may have important public mental health benefits preventing a substantial number of new cases of depression. Disclosure No significant relationships.

Abstract
Introduction
Although defined heterogeneously within the literature apathy is classified as a multidimensional deficit with emotional, behavioral, and cognitive domains in which there is a decrease in self-motivated/goal-directed activity. Recently conceptualized as a syndrome but lacking a universal screening tool.
Objectives
Review current knowledge on apathy and its best therapeutic approach.
Methods
Non-systematic review of literature through search on PubMed/MEDLINE following the terms “apathy”and“psychiatry”.
Results
Apathy is amongst the most frequent symptoms of dementia and highly prevalent across different forms and stages of dementia, including mild cognitive impairment (MCI) as well as other neurodegenerative and psychiatric disorders such as Parkinson’s disease (PD), Schizophrenia, Depression and Brain Injury. Individuals with apathy have higher frequencies of cognitive impairment and are less likely to be compliant/respond to treatment for comorbid illnesses. Apathy reduces quality of life, increases mortality and leads to caregivers distress - often identified as the most burdensome symptom. Once treatment should favor dopaminergic neurotransmission, psychostimulants were considered. Methylphenidate showed encouraging results as well as dopamine agonists but both with limited evidence. Atypical antipsychotics(APs) seem beneficial compared to typical APs. Antidepressants did not improve symptoms and may even worsen them. Previously reported benefits of acetylcholinesterase inhibitors (AChEIs) were not replicated in recent studies except for rivastigmine in PD. Nonpharmacological interventions are also important.
Conclusions
Apathy occurs frequently in a broad range of neuropsychiatric conditions and considering its impact on patients´ quality of life more studies are needed to find an efficient treatment. A consensus regarding definition and screening tools would allow a better approach.

Abstract
Introduction
Attention-Deficit/Hyperactivity Disorder (ADHD) was classically considered a childhood-onset neurodevelopmental condition. Over the past 40 years, it became evident that it can persist during adulthood.
Objectives
The purpose of the authors is to describe the characteristics of ADHD in adults and the specific comorbidities, proposing an approach to these patients.
Methods
A brief non-systematized review is presented, using the literature available on PubMed and Google Scholar.
Results
Only 40-50% of children and adolescents with ADHD will have symptoms that persist into adulthood (estimated adult prevalence of 2.8% across 20 countries; 25% in prisons). A more subtle presentation in adults and the difficulty to access past medical history, lead to diagnosis and treatment rates of lower than 20% (versus 50% in children). Well-characterized core symptoms in children evolve into a predominance of inattention symptoms. They became adults with marked disorganization, difficulties in completing tasks and managing time. Emotional dysregulation is a very prevalent symptom in this population. The comorbidities rate increase over time (reaching 75% of patients).
Conclusions
Adults (or even older subjects) with cognitive and/or behavioural complaints should be submitted to systematic screening for ADHD. Non-treated ADHD symptoms in adulthood are associated with severe impairment, therefore adjustments in the health care system to support the transition from child to adult services are needed.

Abstract
Introduction Alexithymia is considered a personality trait characterized by difficulties in identifying and expressing emotions, impoverished fantasy life and tendency toward action-oriented or ‘operational’ Thinking. There are alterations in cognitive processing and regulation of emotions, and tendency to somatization. Objectives The authors examine literature regarding the concept of alexithymia, exploring the current definition and role in the clinic, research findings and proposed management. Methods A brief non-systematized review is presented, using the literature available on PubMed and Google Scholar. Results Alexithymia is not a discrete psychiatric diagnosis. It has been reported in 9-10% of the general population. It is related to numerous psychiatric disorders (substance use disorders, anxiety disorders, depression and eating disorders), but also to somatic illnesses (essential hypertension, functional gastrointestinal disorders, diabetes mellitus, psoriasis, fibromyalgia and cancer pain). Neuroimaging and neurobiological studies found evidence for morphological and functional brain alterations that integrate the classification introduced by Bermond. Affective type I is characterized by the absence of emotional experience and, consequently, by the absence of cognition accompanying the emotion (associated to right unilateral cortical lesions). Cognitive Type II is characterized by a selective deficit of emotional cognition with sparing of emotional experience (associated to a right-to-left unidirectional deficit in interhemispheric transfer). Conclusions There is little consensus on the subject. Clarification of the mechanisms underlying alexithymia can improve our management of these individuals. Identification of effective strategies could improve the patients’ capacities for adaptive emotional processing and enhance other aspects of functioning. Disclosure No significant relationships.

Abstract
Introduction Lithium has a narrow therapeutic window. Frequent monitoring of both serum levels and clinical signs of toxicity is warranted because toxicity may be present even when concentrations are within the therapeutic range. Persistent neurological signs and symptoms of lithium intoxication gained clinical attention in the 1980s and were named Syndrome of Irreversible Lithium-Effectuated Neurotoxicity (SILENT). Objectives To review the long-term neurological sequelae of lithium intoxication (SILENT) to highlight their clinical presentation, assessment, management and preventive measures. Methods Non-systematic review of literature through search on PubMed/MEDLINE for publications up to 2021, following the terms syndrome of irreversible lithium-effectuated neurotoxicity. Results Neurological manifestations of lithium poisoning may persist, even after effective removal of the drug – SILENT. The most frequent sequelae are cerebellum and brain stem dysfunction, extrapyramidal symptoms and dementia. They may last for weeks, months or years. Infection, dehydration, deteriorating renal function or the addition of other drugs may precipitate acute toxicity. Irreversible damage is difficult to treat. Some cases show spontaneous recovery that may be total, but in others, sequelae persist. Helpful measures include the avoidance of acute intoxications with lithium, long-term and continuous dose adjustment and serum level monitoring, stricter exclusion criteria for starting lithium, and aggressive treatment of acute neurotoxicity. Once the long-term neurologic sequelae have set in, the patient should be managed according to the impediment (physical rehabilitation, speech, cognitive training). Conclusions It is important to raise the awareness of SILENT so that clinicians are able to avoid it. There should be a low threshold for suspecting the existence of toxicity.

Benefits of Pilates in the Elderly Population: A Systematic Review and Meta-Analysis. Eur J Investig Health Psychol Educ 2022; 12:236-268. [PMID: 35323204 PMCID: PMC8947639 DOI: 10.3390/ejihpe12030018] [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] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/10/2022] [Accepted: 02/16/2022] [Indexed: 01/25/2023] Open
Abstract
The aim of this systematic review is to collect and summarize the benefits of Pilates in the elderly population (>60 years old), within the current scientific production, assessing its contribution to Healthy Ageing (HA). We used PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) to select, collect, and analyse this thematic. The methodological procedures were registered in the PROSPERO database. The main results of the studies analysed (n = 30) point to significant differences between the intervention and the control groups in dynamic balance, strength, mobility, functional capacity, risk of falling reduction, and mental and psychological health. Thus, the results showed that Pilates may be beneficial for the health of the elderly. The meta-analysis found statistical differences between means on the dynamic balance (mean difference (MD) = −0.0, 95% CI [−0.71, −0.50]; I2: 0%) and the aerobic capacity and aerobic resistance [(MD) = 38.29, 95% CI [6.82, 69.77]; I2: 0%). Thus, it is concluded that the efficacy of Pilates has been shown in various areas of HA and has proven to be affordable and safe for the majority of people, using just a mat on the floor. Future studies should focus on the analysis of the relationship between the cost and the benefit of a Pilates intervention in the elderly population, to better understand how health costs can be minimized and to contribute to a multidisciplinary and generalized HA. Pilates has practical application for the clinicians, therapists, and health professionals that work with the elderly population.

Monitoring Adherence to Asthma Inhalers Using the InspirerMundi App: Analysis of Real-World, Medium-Term Feasibility Studies. FRONTIERS IN MEDICAL TECHNOLOGY 2022; 3:649506. [PMID: 35047915 PMCID: PMC8757762 DOI: 10.3389/fmedt.2021.649506] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 06/10/2021] [Indexed: 12/11/2022] Open
Abstract
Background: Poor medication adherence is a major challenge in asthma and objective assessment of inhaler adherence is needed. InspirerMundi app aims to monitor inhaler adherence while turning it into a positive experience through gamification and social support. Objective: We assessed the medium-term feasibility of the InspirerMundi app to monitor inhaler adherence in real-world patients with persistent asthma (treated with daily inhaled medication). In addition, we attempted to identify the characteristics of the patients related to higher app use. Methods: Two real-world multicenter observational studies, with one initial face-to-face visit and a 4-month telephone interview, were conducted in 29 secondary care centers from Portugal. During an initial face-to-face visit, patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients took a photo of the medication (inhaler, blister, or others) using the image-based medication detection tool. Medication adherence was calculated as the number of doses taken as a percentage of the number scheduled. Interacting with the app ≥30 days was used as the cut-off for higher app use. Results: A total of 114 patients {median 20 [percentile 25 to percentile 75 (P25–P75) 16–36] years, 62% adults} were invited, 107 (94%) installed the app and 83 (73%) completed the 4-month interview. Patients interacted with the app for a median of 18 [3–45] days, translated on a median use rate of 15 [3–38]%. Median inhaler adherence assessed through the app was 34 [4–73]% when considering all scheduled inhalations for the study period. Inhaler adherence assessed was not significantly correlated with self-reported estimates. Median adherence for oral and other medication was 41 [6–83]% and 43 [3–73]%, respectively. Patients with higher app use were slightly older (p = 0.012), more frequently taking medication for other health conditions (p = 0.040), and more frequently prescribed long-acting muscarinic antagonists (LAMA, p = 0.024). After 4 months, Control of Allergic Rhinitis and Asthma Test (CARAT) scores improved (p < 0.001), but no differences between patients interacting with the app for 30 days or less were seen. Conclusions: The InspirerMundi app was feasible to monitor inhaler adherence in patients with persistent asthma. The persistent use of this mHealth technology varies widely. A better understanding of characteristics related to higher app use is still needed before effectiveness studies are undertaken.

Determinants of the Use of Health and Fitness Mobile Apps by Patients With Asthma: Secondary Analysis of Observational Studies. J Med Internet Res 2021; 23:e25472. [PMID: 34550077 PMCID: PMC8495570 DOI: 10.2196/25472] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 04/01/2021] [Accepted: 06/14/2021] [Indexed: 12/23/2022] Open
Abstract
Background Health and fitness apps have potential benefits to improve self-management and disease control among patients with asthma. However, inconsistent use rates have been reported across studies, regions, and health systems. A better understanding of the characteristics of users and nonusers is critical to design solutions that are effectively integrated in patients’ daily lives, and to ensure that these equitably reach out to different groups of patients, thus improving rather than entrenching health inequities. Objective This study aimed to evaluate the use of general health and fitness apps by patients with asthma and to identify determinants of usage. Methods A secondary analysis of the INSPIRERS observational studies was conducted using data from face-to-face visits. Patients with a diagnosis of asthma were included between November 2017 and August 2020. Individual-level data were collected, including age, gender, marital status, educational level, health status, presence of anxiety and depression, postcode, socioeconomic level, digital literacy, use of health services, and use of health and fitness apps. Multivariate logistic regression was used to model the probability of being a health and fitness app user. Statistical analysis was performed in R. Results A total of 526 patients attended a face-to-face visit in the 49 recruiting centers and 514 had complete data. Most participants were ≤40 years old (66.4%), had at least 10 years of education (57.4%), and were in the 3 higher quintiles of the socioeconomic deprivation index (70.1%). The majority reported an overall good health status (visual analogue scale [VAS] score>70 in 93.1%) and the prevalence of anxiety and depression was 34.3% and 11.9%, respectively. The proportion of participants who reported using health and fitness mobile apps was 41.1% (n=211). Multivariate models revealed that single individuals and those with more than 10 years of education are more likely to use health and fitness mobile apps (adjusted odds ratio [aOR] 2.22, 95%CI 1.05-4.75 and aOR 1.95, 95%CI 1.12-3.45, respectively). Higher digital literacy scores were also associated with higher odds of being a user of health and fitness apps, with participants in the second, third, and fourth quartiles reporting aORs of 6.74 (95%CI 2.90-17.40), 10.30 (95%CI 4.28-27.56), and 11.52 (95%CI 4.78-30.87), respectively. Participants with depression symptoms had lower odds of using health and fitness apps (aOR 0.32, 95%CI 0.12-0.83). Conclusions A better understanding of the barriers and enhancers of app use among patients with lower education, lower digital literacy, or depressive symptoms is key to design tailored interventions to ensure a sustained and equitable use of these technologies. Future studies should also assess users’ general health-seeking behavior and their interest and concerns specifically about digital tools. These factors may impact both initial engagement and sustained use.

Abstract
Background and Aims
Renal manifestations of IgM gammopathy are less common than those seen in patients with multiple myeloma. However, a wide spectrum of kidney diseases has been described in previous publications. We aim to characterize kidney involvement in patients with Waldenström Macroglobulinemia and IgM-secreting B cell lymphoproliferative disorders.
Method
We retrospectively studied 7 patients with a circulating monoclonal IgM and renal histology showing evidence of monoclonal immunoglobulin deposits or lymphomatous infiltration. Demographic, clinical and laboratory data were collected.
Results
Of the 7 patients studied, four (57%) were male and the median age was 68 years old (range 41-79). Among the 7 patients, 5 met criteria for Waldenström Macroglobulinemia after bone marrow biopsy; none of them had hyperviscosity syndrome. Four patients presented with nephrotic syndrome and all had impaired renal function and hypertension. Four patients had microscopic hematuria and only one patient showed no proteinuria. Mean serum creatinine levels were 2.9mg/dL. Renal biopsy showed different patterns of renal injury, including typical intracapillary monoclonal deposits disease (5 patients), membranoproliferative glomerulonephritis with cryoglobulinemia (1 patient), AL-amyloidosis (1 patient) and interstitial lymphoplasmacytic infiltration with CD20+ lymphocytes associated with minimal change disease. Follow-up data were obtained in 4 patients: 3 underwent chemotherapy but only one achieved complete remission and 2 progressed to end-stage renal disease.
Conclusion
Although rare, Waldenström Macroglobulinemia and IgM gammopathy are responsible for diverse manifestations of renal disease. A prompt diagnosis is of utmost importance in order to ensure early start of therapy, which should be directed at the underlying hematologic disorder, to improve renal survival.

Abstract
BACKGROUND Poor medication adherence is a major challenge in asthma, and objective assessment of inhaler adherence is needed. The InspirerMundi app aims to monitor adherence while providing a positive experience through gamification and social support. OBJECTIVE This study aimed to evaluate the feasibility and acceptability of the InspirerMundi app to monitor medication adherence in adolescents and adults with persistent asthma (treated with daily inhaled medication). METHODS A 1-month mixed method multicenter observational study was conducted in 26 secondary care centers from Portugal and Spain. During an initial face-to-face visit, physicians reported patients' asthma therapeutic plan in a structured questionnaire. During the visits, patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients registered the intake (inhaler, blister, or other drug formulation) by using the image-based medication detection tool. At 1 month, patients were interviewed by phone, and app satisfaction was assessed on a 1 (low) to 5 (high) scale. Patients were also asked to point out the most and least preferred app features and make suggestions for future app improvements. RESULTS A total of 107 patients (median 27 [P25-P75 14-40] years) were invited, 92.5% (99/107) installed the app, and 73.8% (79/107) completed the 1-month interview. Patients interacted with the app a median of 9 (P25-P75 1-24) days. At least one medication was registered in the app by 78% (77/99) of patients. A total of 53% (52/99) of participants registered all prescribed inhalers, and 34% (34/99) registered the complete asthma therapeutic plan. Median medication adherence was 75% (P25-P75 25%-90%) for inhalers and 82% (P25-P75 50%-94%) for other drug formulations. Patients were globally satisfied with the app, with 75% (59/79) scoring ≥4,; adherence monitoring, symptom monitoring, and gamification features being the most highly scored components; and the medication detection tool among the lowest scored. A total of 53% (42/79) of the patients stated that the app had motivated them to improve adherence to inhaled medication and 77% (61/79) would recommend the app to other patients. Patient feedback was reflected in 4 major themes: medication-related features (67/79, 85%), gamification and social network (33/79, 42%), symptom monitoring and physician communication (21/79, 27%), and other aspects (16/79, 20%). CONCLUSIONS The InspirerMundi app was feasible and acceptable to monitor medication adherence in patients with asthma. Based on patient feedback and to increase the registering of medications, the therapeutic plan registration and medication detection tool were redesigned. Our results highlight the importance of patient participation to produce a patient-centered and engaging mHealth asthma app.

Abstract
Western diets are poor in healthy n3 polyunsaturated fatty acids, such as docosahexaenoic acid. Since microalga Aurantiochytrium sp. is rich in docosahexaenoic acid, a functional food based on lean yogurt and this microalga was tested. This study entailed characterizing the lipid fraction and determining the fatty acid bioaccessibility. The tested yogurts (control and 2% w/w, Aurantiochytrium sp.) had differences. Docosahexaenoic acid was not detected in the control product, but it was the second most important fatty acid in Aurantiochytrium sp. and Aurantiochytrium yogurt, 29.7 ± 0.4% and 18.7 ± 2.0%, respectively. Based on the fatty acid profile only, an amount of 158.7 g of Aurantiochytrium yogurt in wet weight terms would be required to ensure an appropriate intake of healthy fatty acids. Generally, the fatty acid bioaccessibility was not high, remaining below 60-70% in almost all cases. Considering the docosahexaenoic acid bioaccessibility (44 ± 3%), an amount of 360.7 g of Aurantiochytrium yogurt would be advisable. A reasonable dietary prescription would be a daily consumption of 125 ml of Aurantiochytrium yogurt.

Abstract
Neuronal aging increases the risk of late-onset Alzheimer's disease. During normal aging, synapses decline, and β-amyloid (Aβ) accumulates intraneuronally. However, little is known about the underlying cell biological mechanisms. We studied normal neuronal aging using normal aged brain and aged mouse primary neurons that accumulate lysosomal lipofuscin and show synapse loss. We identify the up-regulation of amyloid precursor protein (APP) endocytosis as a neuronal aging mechanism that potentiates APP processing and Aβ production in vitro and in vivo. The increased APP endocytosis may contribute to the observed early endosomes enlargement in the aged brain. Mechanistically, we show that clathrin-dependent APP endocytosis requires F-actin and that clathrin and endocytic F-actin increase with neuronal aging. Finally, Aβ production inhibition reverts synaptic decline in aged neurons while Aβ accumulation, promoted by endocytosis up-regulation in younger neurons, recapitulates aging-related synapse decline. Overall, we identify APP endocytosis up-regulation as a potential mechanism of neuronal aging and, thus, a novel target to prevent late-onset Alzheimer's disease.

Abstract
Introduction Psychiatric rehabilitation promotes recovery in individuals with mental disabilities. Its mission is to engage patients and families or caregivers in a collaborative treatment process. The vision of recovery is more likely to become a reality when patients and families are actively involved in treatment. Numerous factors have converged during the past decades to facilitate development and refinement of evidence-based approaches for strengthening families coping with mental disorders. Objectives To review current knowledge on the importance of involving families in psychiatric treatment and rehabilitation, addressing effectiveness of family interventions, role of family coping skills in neutralizing stress and vulnerability, and family burden of mental illness. Methods Non-systematic review of literature through search on PubMed/MEDLINE database for publications up to 2020. Textbooks were consulted. Results Given the unpredictability of major mental disorders, families assume responsibility for extensive monitoring and supervision of a severely and chronically mentally ill relative. Clinical, social, family and economic benefits are achieved by adding psychosocial family interventions to a comprehensive array of services required by patients. Family interventions are not stand-alone modalities: they are coordinated with pharmacotherapy, illness management, crisis intervention, clinical case management, skills training and supportive services. Family interventions show benefits, such as fewer psychotic/affective episodes of exacerbation or relapse by the patient, reduced hospitalizations and improved family morale and less emotional burden. Conclusions The new and effective family interventions do not stigmatize families as being ‘sick’ or in need of therapy to ‘straighten them out’. Family interventions are viewed as conferring added therapeutic protection to the patient and relatives. Disclosure No significant relationships.

Abstract
IntroductionFrontotemporal Demential (FTD) is a neurodegenerative disorder evolving the frontal or temporal brain lobes. They have been described six variants. Behaviour variant (BvFTD) is the most common, and is characterized by changes in social behaviour and conduct, with loss of social awareness and poor impulse control. Hebephrenic schizophrenia (HSz), or disorganized schizophrenia, was recognized as a schizophrenia subtype, characterized by desorganized behaviour and a cognitive deteriorization. Subtypes of schizophrenia are no longer recognized as separate conditions neither in the Diagnostic and Statistical Manual of Mental Disorders, nor in the new International Statistical Classification of Diseases.ObjectivesTo review the literature about the concepts of hebephrenic schizophrenia and their similarities with the concept of frontotemporal dementiaMethodsNarrative review of the literature on PubMed/MEDLINE, using the keywords “hebephrenic szchizophrenia” AND “frontotemporal dementia”. Only articles in English were included.ResultsSome authors described dificulty in establish a diferential diagnosis between HSz and BvFTD. HSz has an earlier onset. However, BvFTD is an early age dementia. The fenomenology of both diseases is similar, and schizophrenia was historical conceptualized as praecox dementia. Frontotemporal abnormalities are common neuroimagiological findings in schizophrenia. Clinically, FTD shows a profound alteration in personality and social conduct, emotional blunting and loss of insight. Memory, intellectual functions, executive and attentional abilities may be disturbed in both.ConclusionsA diferential diagnosis between HSz and BvFTD is dificult to establish (clinically and imagiologically). The response to treatment is weak in both. It should be investigated the possibility they could be the same syndrome, onseting in diferent ages.DisclosureNo significant relationships.

Abstract
Introduction Traumatic brain injury (TBI) is a leading cause of morbidity and mortality, giving rise to a variety of neuropsychiatric syndromes associated with great functional impairments, chronic disability and poor quality of life. Depending on diagnostic criteria, 20-90% of victims of TBI develop at least one neuropsychiatric manifestation in the first month, and about 40% present at least three symptoms during three months, with higher incidence in females. Survivors of TBI are at increased risk for development of severe, long-term psychiatric disorders. The aetiology of these disturbances remains unclear. Objectives To review current knowledge on the neuropsychiatric consequences associated with TBI. Methods Non-systematic review of literature through search on PubMed/MEDLINE database for publications up to 2020, following the terms “traumatic brain injury” and “neuropsychiatry”. Results Although the experience of neuropsychiatric symptoms may be temporary and may resolve in the acute period, many patients with TBI can experience psychopathology that is persistent or that develops in the post-acute period, regardless of injury severity. These symptoms can involve personality changes, psychosis, major depression, generalized anxiety disorder, post-traumatic stress disorder, maladaptive social behaviours, poor disability adjustment, reduced coping skills and cognitive impairment. Evidence remains insufficient to conclude the role of TBI-related neuropathological consequences in the development of post-TBI neuropsychiatric disorder. Non-organic factors are also implicated in its generation and maintenance. Conclusions Neuropsychiatric sequelae are common following TBI. Several of these syndromes are amenable to treatment. Further investigations are required to better understand the mechanistic aetiology of these conditions and the effectiveness of therapeutic modalities.

Abstract
IntroductionStudies have consistently found that many individuals with psychosis experience significant delays before receiving treatment. DUP refers to the period between the emergence of psychotic symptoms and the initiation of appropriate clinical treatment.ObjectivesTo review current knowledge on the best approach for patients with schizophrenia (SCZ) and prolonged DUP.MethodsNon-systematic review of literature through search on PubMed database, following the terms “DUP and treatment” and “impact of longer DUP”. Two clinical cases are described.ResultsThe clinical cases describe patients with SCZ with DUPs older than 10 years, in whom we could not achieve complete clinical remission after several therapeutic trials and whose prognosis was admitted as reserved. Longer DUP is an independent predictor of poorer outcome in SCZ, including the poor response to treatment and difficulty in achieving remission, predicting treatment resistance. Identifying treatment-resistant patients is crucial due to the importance of initiating clozapine as early as possible since the chances of responding are higher.ConclusionsDUP is a key prognostic variable in psychosis, revealing the significance of early treatment. Patients with long DUP should be regarded as at high risk of poor recovery. The detection of these patients enables clinicians to avoid unnecessary exposure to ineffective treatments while effective interventions are delayed. However, in view of adverse side effects of clozapine, future studies need to examine relevant predictors to detect accurately non-responders. We also suggest further studies to understand if there is correspondence between DUP and different stages of the disease that justify these results.

Abstract
Background To evaluate retinal morphological and vascular parameters in patients recently diagnosed with obstructive sleep apnea syndrome (OSAS) and determine the correlation between retinal vascular density and the severity of OSAS. Methods We performed a retrospective study on the retinal vasculature of patients with OSAS and age-match healthy controls. OSAS was confirmed by full-night cardiorespiratory polygraphy. Patients were divided into three groups according to disease severity given by apnea-hypopnea index (AHI) i.e., mild, moderate or severe. Retinal thicknesses and vascular density were compared among groups, for both the macula and optic disc. Correlation between vascular density and clinical features were also assessed. Results The study included 30 eyes of patients with OSAS and 12 controls. No differences were found regarding retinal thickness in both the macula and the optic disc between OSAS patients and controls. In contrast, significant differences were found in the peripapillary vessel density between groups versus control patients. The greatest difference being between severe OSAS and controls (49.4% ± 2.1 versus 40.4% ± 4.2 respectively, p=0.01). Peripapillary vessel density was found to significantly and negatively correlate with AHI (p=0.02; r= -0.74) and directly correlate with the lowest percutaneous oxygen saturation (p=0.02; r= 0.58). Conclusions This study indicates that OSAS is associated with retinal microvasculature impairment, that seems to mainly affect the optic disc. This suggests that microvascular damage increases with the increasing severity of OSAS. As such, prospective trials are needed to clarify if this vascular peripapillary damage precedes glaucomatous optic neuropathy in OSAS patients.

Abstract
Abstract
Background
Peripartum cardiomyopathy (PPCM) is a rare but serious condition that affects childbearing women. Dopamine agonists (DAs) may represent a specific therapy, potentially facilitating left ventricular recovery, through inhibition of prolactin secretion. However, their therapeutic value in this setting has not been fully demonstrated.
Purpose
To perform a meta-analysis aimed at evaluating the extent to which DAs are able to interfere with the natural history of PPCM.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library, Google Scholar, Scopus and DARE for both randomized controlled trials (RCTs) and observational studies addressing the impact of DAs on main outcomes of PPCM patients, published up until February 1, 2020. Endpoints were those of mortality, recovery from heart failure and, likewise, the degree to which left ventricular ejection fraction (LVEF) was restored. All analyses were conducted under a DA plus optimized medical therapy (OMT) vs. OMT alone design, while results were pooled using traditional meta-analytic techniques, under a random-effects model. Odds ratios (ORs) were computed for the first two outcomes, whereas mean difference (MD) was calculated to quantify LVEF restoration.
Results
2 RCTs, 2 prospective cohort, 1 prospective case-control and 2 retrospective cohort studies, encompassing 452 patients, were regarded as eligible for quantitative evaluation. 180 patients were allocated to the DA arm, which was mostly represented by bromocriptine; in fact, only 1 study, including 24 patients, specified cabergolin utilization. Overall, 5 papers including 295 patients reported 42 deaths, whereas 5 papers comprising 305 patients detailed 220 heart failure recoveries, thus unveiling that LVEF restoration was the norm. The addition of a DA to OMT provided no signal of a survival benefit (OR 0.71, 95% CI 0.27–1.87, p=0.49, i2=27%). On the other hand, the incorporation of a DA into the therapeutic regimen narrowly missed significance for the heart failure recovery endpoint (OR 2.68, 95% CI 0.98–7.31, p=0.05, i2=56%). Furthermore, DAs were demonstrated to incrementally improve LVEF by 15% (MD 15.00, 95% CI 10.24–19.76, p<0.00001, i2=77%). Adverse events, including thromboembolic ones, were rare, though adjunct anticoagulation was broadly reported.
Conclusion
In PPCM patients, the addition of a DA to OMT seems to be both effective at incrementally improving LVEF and safe, even though not reaching survival benefit status. These findings appear to corroborate the so-called prolactin hypothesis for PPCM pathophysiology.

Abstract
Abstract
Background
Statins are highly effective in preventing major acute cardiovascular events in the setting of atherosclerotic arterial disease. On the other hand, given their antithrombotic and anti-inflammatory properties, statins may also attenuate patients' odds of developing venous thromboembolism (VTE). However, clinical studies have yielded variable estimates of this effect.
Purpose
To perform a meta-analysis designed to evaluate the extent to which statin use influences the rate of subsequent VTE events.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library and Google Scholar for both randomized controlled trials (RCTs) and observational studies addressing the association between statins and VTE risk, published up until December 1, 2019. Manually reviewed references and key investigators interaction via e-mail correspondence were also data sources. RCTs comparing the effects of statin therapy with those of a placebo or no treatment were included, while interventional studies appraising different lipid-lowering pharmacological strategies were not. Observational studies encompassed both cohort and case-control designs. The primary endpoints were general VTE, deep vein thrombosis or pulmonary embolism. Patients with cancer, heart failure and chronic kidney disease (CKD) were further investigated separately. Study-specific relative risks (RRs) were pooled using generic inverse variance outcome meta-analytic technique with a random-effects model.
Results
23 RCTs comprising 118.464 participants, 12 cohort studies encompassing 2.881.184 patients and 9 case-control studies including 354.367 patients were regarded as eligible for quantitative evaluation. Specifically, 5 observational studies comprising 9.656 cancer patients, 3 studies encompassing 9.693 heart failure patients and 4 studies including 4.353 CKD patients were gathered. In RCTs, statin therapy was proven slightly superior to placebo or no treatment in lowering VTE incidence (RR 0.85, 95% CI 0.73–0.99, p=0.04, i2=14%). Observational studies were found to corroborate this effect, with statin treatment resulting in VTE risk reduction overall (RR 0.72, 95% CI 0.64–0.81, p<0.001, i2=84%) and in both cohort (RR 0.86, 95% CI 0.83–0.90, p<0.001, i2=85%) and case-control (RR 0.68, 95% CI 0.57–0.82, p<0.001, i2=80%) designs. This positive effect held true in cancer patients (RR 0.56, 95% CI 0.33–0.95, p=0.03, i2=78%), but not in those with heart failure (RR 0.7, 95% CI 0.42–1.16, p=0.17, i2=2%) and CKD (RR 1.04, 95% CI 0.67–1.60, p=0.87, i2=0%).
Conclusion
Currently available evidence suggests that statins significantly reduce patients' odds of developing VTE. Given their favorable safety profile and low cost, statin treatment should now be considered in high-risk individuals, particularly in those with cancer.

Abstract
Abstract
Background
Among all subsets of coronary artery lesions, bifurcations stand out due to high incidence, demanding percutaneous interventions (PCIs) and poor outcomes. Amid the different PCI strategies, the provisional (PS) approach is generally recommended over 2-stent (TS) techniques, but this paradigm has been challenged.
Purpose
To compare PS with TS for PCI of coronary bifurcation lesions, concerning procedural aspects and both immediate and long-term patient outcomes.
Methods
Retrospective study encompassing patients consecutively referred to a tertiary interventional cardiology unit for coronary angiography, who were found to have at least 1 native bifurcation lesion. According to operator experience and angiographic features, patients were managed with PS or/(and) TS. Procedural aspects regarding radiological variables, angiographic success and immediate complications were reviewed, as were in-hospital outcomes. Besides, clinical follow-up, by clinic appointment or telephone calling, was performed targeting stent failure, target vessel revascularization (TVR), acute coronary syndromes (ACS), heart failure and mortality.
Results
From January 2010 to June 2017, 404 patients with 433 bifurcation lesions were included. Median age was 70 (62–77) years and 25.3% were female. Median follow-up was 2 (1–3) years. Chronic angina was the dominant PCI context (61.3%) with 9.7% presenting with ST-segment elevation myocardial infarction (MI). Medina class 1,1,1 was documented in 54.1% and 64.9% of lesions were hailed as true bifurcations. 303 patients underwent PS, whereas 67 were managed with TS, with TAP (43.3%) and mini-crush (34.3%) as the leading techniques. True bifurcations were more frequently approached with TS (p<0.001), whereas PCI context did not influence procedure selection. Fluoroscopy time (p<0.001), radiation dose (p=0.003) and contrast volume (p=0.009) were higher in the TS subgroup. OCT guidance (p=0.039) was also more common with TS. Angiographic success was uniformly high (95.1% for PS and 97% for TS), while procedural complications, including iatrogenic coronary dissections (7.4%, mostly minor) and slow-reflow (3.5%), were homogenously low. Acute kidney injury and type 4a MI occurred in 14.5% and 32.3%, respectively, also with no difference between groups. As for long-term outcomes, stent failure, encompassing both stent thrombosis (1 event) and restenosis (4.2%), occurred more often with TS (p=0.046), with ACS events (9.5%) following the same trend (p=0.08). In turn, rates of TVR (12.5%), heart failure hospitalization (6.2%) and mortality, regardless of its cardiovascular nature, were similar.
Conclusion
PS outperforms TS during follow-up, particularly due to lower stent failure odds. Thus, this study further supports the concept of PS as the standard approach for coronary bifurcation lesions.

Abstract
Abstract
Background
Aspirin has been a mainstay of antiplatelet therapy for coronary artery disease (CAD). However, in the context of variant angina (VA), high-dose aspirin was reported to exacerbate coronary spasms. Consequently, the value of traditional low-dose aspirin in VA, especially if not associated with atherosclerotic CAD, may be disputed.
Purpose
To perform a meta-analysis aimed at evaluating the extent to which low-dose aspirin therapy influences cardiovascular (CV) prognosis in VA.
Methods
We systematically searched MEDLINE, Embase, Web of Science, Cochrane Library and Google Scholar for studies addressing the long-term impact of low-dose aspirin on main CV outcomes of VA patients, published up until February 1, 2020. The primary endpoint was all-cause mortality, whereas secondary endpoints included CV mortality, acute coronary syndrome (ACS) events, revascularization procedures and hospital admissions for angina. The subgroup of patients with no significant epicardial CAD was further investigated separately, underneath similar outcomes. Study-specific odds ratios (ORs) were pooled using traditional meta-analytic techniques, under a random-effects model.
Results
One prospective multicenter and two retrospective single-center studies, encompassing 1652 and 1164 patients, respectively, were regarded as eligible for quantitative evaluation. Median follow-up ranged between 12 and 52.1 months. 1284 patients were allocated to the aspirin arm and 2770 had no epicardial CAD. Absolute number of events for each endpoint may be reported as follows: all-cause mortality, 33; CV mortality, 11; ACS, 57; revascularization, 14; hospital admission for angina, 218. Aspirin was not found to reduce neither all-cause mortality (OR 0.78, 95% CI 0.38–1.58, p=0.49, i2=0%), nor CV mortality (OR 0.98, 95% CI 0.30–3.25, p=0.98, i2=0%), nor ACS events (OR 1.44, 95% CI 0.51–4.10, p=0.49, i2=47%), nor revascularization procedures (OR 2.06, 95% CI 0.63–6.75, p=0.23, i2=0%), nor hospital admissions for angina (OR 1.60, 95% CI 0.67–3.80, p=0.29, i2=86%). Likewise, this comprehensively neutral effect held true in those with VA and no significant atherosclerotic CAD (OR 1.04, 95% CI 0.28–3.92, p=0.95, i2=0%, for CV mortality; OR 1.29, 95% CI 0.19–8.94, p=0.79, i2=33%, for revascularization; OR 1.73, 95% CI 0.81–3.73, p=0.16, i2=75%, for hospital admission for angina).
Conclusion
Even though scarce, currently available evidence suggests that low-dose aspirin is not effective in shrinking major adverse cardiovascular events in VA patients, particularly in those with no epicardial CAD. On the other hand, lower doses of aspirin may avoid the menace of clinically significant coronary spasms.

Abstract
Abstract
Background
Currently available pharmacological options for rhythm control in atrial fibrillation (AF) are overshadowed by suboptimal efficacy and both frequent and potentially severe adverse events. Recent studies have added evidence to the hypothesis that ranolazine might exert antiarrhythmic effects, particularly in atrial tachyarrhythmias.
Purpose
To perform a systematic review with meta-analysis in order to ascertain the potential role of ranolazine in the management of AF.
Methods
We systematically searched MEDLINE, Embase and Scopus for randomized controlled trials (RCTs) and cohort studies addressing the association between ranolazine and AF outcomes, published up until December 1, 2019. The primary endpoint was incidence of AF, which was evaluated under a ranolazine versus placebo design. In this regard, patients in the setting of postcardiac surgery were further investigated separately. Secondary endpoints included AF cardioversion outcomes, which were addressed through comparison between ranolazine plus amiodarone and amiodarone alone for proportional efficacy and temporal requirements (time-to-cardioversion). The latter analysis was also undertaken in a dose-sensitive fashion (≤1000mg vs. 1500mg of ranolazine). Tertiary endpoints covered AF burden and episodes, in paroxysmal AF patients, and safety outcomes, namely death, QTc interval prolongation and hypotension. Study-specific odds ratios (ORs) were pooled using meta-analytic techniques with a random-effects model.
Results
A total of 10 RCTs comprising 8.109 participants and 3 cohort studies encompassing 37.112 patients were regarded as eligible for evaluation. Ranolazine was found to attenuate patients' odds of developing AF (OR 0.53, 95% CI: 0.41–0.69, p<0.001, i2=58%). This effect held true, with an even larger effect size, in the context of post-cardiac surgery (OR 0.34, 95% CI: 0.16–0.72, p=0.005, i2=64%). Ranolazine increased the chances of successful AF cardioversion when added to amiodarone over amiodarone alone (OR 6.67, 95% CI: 1.49–29.89, p=0.01, i2=76%), while significantly reducing time-to-cardioversion [SMD 9.54h, 95% CI: −13.3–5.75, p<0.001, i2=99%]. Interestingly, cardioversion was faster with ≤1000mg of ranolazine (SMD −13.16h, 95% CI: −15.07–11.25, p<0.001, i2=95%) than with 1500mg (SMD −3.57h, 95% CI: −5.06–2.08, p<0.001, i2=23%). In paroxysmal AF, ranolazine was also proved to significantly reduce both AF burden and episodes. There were no safety signals regarding mortality odds, QTc interval prolongation (mostly clinically insignificant) and hypotension (mostly transitory).
Conclusion
Current evidence suggests that ranolazine provides an effective and safe option for a chemical rhythm control strategy in AF management, a field in which medical breakthroughs are desperately needed.

Abstract
Background Full level 1 personal protective equipment (PPE) is used in various domains and contexts. Prior research has shown influences of such equipment on performance, comfort, and contamination levels. The coronavirus disease (COVID-19) pandemic forced a pervasive requirement of PPE, with little preparation, rushed deployment, inadequate time for training, and massive use by personnel who are inexperienced or not qualified in its effective use. Objective This study aims to examine the key human factors (physical and ergonomic, perceptual and cognitive) that influence the use of level 1 PPE when attending to patients with suspected or confirmed COVID-19. Methods The research approach consisted of a short survey disseminated to health care professionals in two countries, Israel and Portugal, with similar demographics and health care systems. The survey included 10 items with a 5-point Likert scale regarding the key human factors involved in level 1 PPE, as identified in prior research. Results A total of 722 respondents from Israel and 301 respondents from Portugal were included in the analysis. All the respondents reported using level 1 PPE with patients with COVID-19 in the range of several hours daily to several hours weekly. The Cronbach α was .73 for Israel and .75 for Portugal. Responses showed high levels of difficulty, with medians of 4 for items related to discomfort (n=539/688, 78% in Israel; n=328/377, 87% in Portugal), hearing (n=236/370, 64% in Portugal; n=321/642, 50% in Israel), seeing (n=697/763, 89% in Israel; n=317/376, 84% in Portugal), and doffing (n=290/374, 77% in Portugal; n=315/713, 44% in Israel). A factor analysis showed a set of strongly related variables consisting of hearing, understanding speech, and understanding the situation. This suggests that degradation in communication was strongly associated with degradation in situational awareness. A subsequent mediation analysis showed a direct effect of PPE discomfort on situational awareness (P<.001); this was also influenced (mediated) by difficulties in communicating, namely in hearing and understanding speech. Conclusions In 2020, the COVID-19 pandemic is paving the way for updating PPE design. The use of already deployed technology affords ample opportunities to improve, adapt, and overcome caveats. The findings here suggest that the use of level 1 PPE with patients with COVID-19 has perceptual and cognitive effects, in addition to physical and ergonomic influences. Efforts should be taken to mitigate the harmful effects of such influences, both regarding the performance of medical actions and the risk of contamination to health care workers. Such efforts involve the design of PPE; the introduction of technologies to enhance vision, hearing, and communicating during the use of PPE; and training staff in using the equipment and in effective communication and teamwork protocols.

Abstract
Abstract
Background
Syncope is a very common reason for presenting to the emergency department (ED). The existence of a telemetry unit is crucial but it is not the reality in some hospitals. In order to avoid unnecessary ward admission, 24-hour Holter (24HH) monitoring could be useful to help with the diagnosis (when the arrhythmic etiology is suspected and the symptoms are frequent enough) and also be important to safely discharge a patient.
Purpose
The purpose of this study is to evaluate the diagnostic performance of 24HH monitoring, during a syncope episode in the ER, and to compare the readmission rates between patients with normal and abnormal not diagnostic 24HH monitoring.
Methods
A cohort study of consecutive patients (P) who were monitored with 24HH in one hospital in the ED, between January 2015 and December 2017, were included. All the 24HH results were seen by a senior cardiologist and divided in three groups: A - normal, B - abnormal Holter study unlikely to explain syncope and C- Holter study considered to be diagnostic.
Groups A and B were compared using chi-square independence test to evaluate association between the result of the 24HH and readmission rates at 30 days and 1 year, as well as mortality and device implantation at 1 year. Multivariate logistic regression was used to look for other confounders.
Results
A total of 111 P were included in this study. Mean age was 75 ± 14 years old, with 55.6% male patients.
A previous emergency episode with syncope was present in 56.9% of P. The mortality at one-year follow-up was 11.9%. The 24HH was considered diagnostic in 25.2% of P (28 P), with 18.9% of all the P with necessity of pacemaker (PM) implantation. In the patients with a non-diagnostic 24HH, 6,4% implanted a loop recorder before discharge.
Group B patients had a higher 30-day readmission rate to the ED when compared with group A (OR = 4.050 CI 95 [1.13 – 14.497], p = 0.033), but no difference in one-year readmission rate (p= 0.065). There was no difference in one-year mortality between the two groups (p= 0.731) or in one-year implantation of pacemaker (p= 0.431).
Conclusion
The use of 24HH in the ED could be a valuable tool in the diagnosis of rhythm disorders that cause syncope. An abnormal non diagnostic result can still be a predictor of 30-day readmission to the ED with similar complaints.

Abstract
Abstract
Background: The possibility of prompt interaction with the involved professionals in a health system has a great positive impact and represents one of the determining factors for the quality of care provided to cancer patients. Breast cancer treatment involves the use of long-term therapies, most of them oral, with constant possibility of side effects which are frequently not reported during medical visits. Trials using digital platforms for patient electronic monitoring have showed increased survival and patient satisfaction, favoring to the adoption of this strategy. In Brazil, to our knowledge, no such trials have been conducted. CLION / CAM Group is a large multidisciplinary private oncology practice located in the northeast part of Brazil, mostly dedicated to the care of breast cancer patients. Here we describe our experience in developing and implementing a digital platform to improve patient care and further developments focused on treatment side effects and patients reported outcomes. Methods: The project started in May 2017 with the development of a mobile platform (versions web, iOS and Android-based) and internal tests. In January 2018 the platform was lunched with a chat center specifically designed for the patient and multidisciplinary team (doctors and nurses initially). To improve user experience, some implementations were idealized: 1) groups for multidisciplinary case discussion on a safe digital environment; 2) fast and friendly view of the medical agendas and scheduling of each patient through the application; 3) integration with the electronic health record; 4) sending questionnaires to specific groups, allowing monitoring of therapeutic adherence to oral medications and more complex adverse reactions. Results: until July 7th 2019, 601 users downloaded the mobile platform. There were 31 doctors, 32 non-medical professionals (nursing staff, pharmacy, nutrition, psychology, physical therapist and dentistry) and 538 patients, of whom, 425 with breast cancer diagnosis including 121 taking oral therapy. A total of 1537 chats were initiated, with 27886 messages, 1618 images and 160 documents exchanged. Conclusion: Implementing a digital mobile platform for cancer patient care is feasible in a private oncology practice in Brazil and resulted in an intense and productive multidisciplinary team interaction. Systems of this nature should be encouraged in order to keep the communication channel open to patients and families, improving the care to be rendered. Simple measures, inexpensive to the health care system and, demonstrably, highly effective. A prospective clinical trial comparing patient reported outcome with conventional care vs using the mobile platform is been developed with breast cancer patients using oral oncologic drugs at our institution.

Abstract
Cystic lymphangioma mainly occurs in children and develops from the lymphatic vessels. The present study reports the case of a 36-year-old female patient with a giant cystic mediastinal lymphangioma. She was asymptomatic and the diagnosis was accidental. Imaging studies are important for referral to the Cardio-Thoracic Surgery Department for surgical intervention in order to remove the lesion. It is important that in the case of an enlargement of the mediastinum observed in a thoracic X-ray, the possible diagnosis takes into consideration various hypotheses. Early diagnosis may prevent further growth and infiltration of structures that hinder the surgical approach. LEARNING POINTS Cystic lymphangioma corresponds to approximately 0.7 to 4% of all mediastinal tumours.They are usually asymptomatic and, in adults, the diagnosis is accidental.After an imaging study with computed tomography and nuclear magnetic resonance, patients are usually candidates for surgical excision.

Abstract
Abstract
A 62-year-old male, was admitted in the emergency department with chest discomfort and dyspnea for the last 2 days; he also referred pain on the right leg. He had been submitted to prostatic surgery 1 month before and since then he reduced is usual physical activity. At admission he was normotensive, with sinus tachycardia, with elevated D-Dimers and hypoxemia and hypocapnia on arterial blood gas analysis. Transthoracic echocardiogram (TTE) was performed and it showed dilation of right ventricle with diastolic left ventricular "D-shape" compatible with right ventricle pressure overload. Furthermore, it was visible a large and filiform thrombus on the right atrium, causing procidency into the right ventricle through the tricuspid valve during diastole (image top-left and top-right). Patient was hemodynamically stable at that time, and the case was promptly discussed with cardiothoracic surgery. The decision was to adopt a conservative strategy, and non-fractioned heparin (NFH) perfusion was initiated accordingly to local protocol.
Patient remained hemodynamically stable, and, after 24h of treatment with NFH echocardiographic re-evaluation showed disappearance of the thrombus previously seen of the right chambers (image bottom-left). Angio-TC scan of thorax performed at that time showed extensive bilateral pulmonary thromboembolism, but with normal perfusion of the pulmonary artery trunk and both right and left pulmonary arteries. After 48h of NFH the patient started oral anticoagulation. The rest of the admission was unremarkable apart from a respiratory tract infection successfully treated with piperacillin-tazobactam.
Pre-discharge TTE performed 12 days after admission showed no dilation of the right ventricle, with normal systolic function (image bottom-right), as well as no evidence of pulmonary arterial hypertension.
Discussion
Large right atrial thrombus in the setting of PTE is a clinical situation in which there is no consensus regarding clinical management. In most cases, management is dictated by haemodynamic status of the patient. In the setting of a hemodynamically stable patient, systemic anticoagulation can be an option. Surgery, fibrinolysis and percutaneous aspiration have also been advocated. Successful treatment of right heart thrombus with anticoagulation alone has been reported, but there are also reports of unsuccess with that strategy. This is a case of a successful treatment with anticoagulation alone and so, we currently consider that the choice of treatment strategy based on hemodynamic status continues to be the wisest strategy to adopt.

Abstract
OBJECTIVE We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance. DESIGN Baseline data from two prospective multicentre observational studies. SETTING 29 allergy, pulmonology and paediatric secondary care outpatient clinics in Portugal. PARTICIPANTS 395 patients (≥13 years old) with persistent asthma. MEASURES Data on demographics, patient-physician relationship, upper airway control, asthma control, asthma treatment, forced expiratory volume in one second (FEV1) and healthcare use were collected. Patients and physicians independently assessed adherence to inhaled controller medication during the previous week using a 100 mm Visual Analogue Scale (VAS). Discordance was defined as classification in distinct VAS categories (low 0-50; medium 51-80; high 81-100) or as an absolute difference in VAS scores ≥10 mm. Correlation between patients' and physicians' VAS scores/categories was explored. A multinomial logistic regression identified the predictors of physician overestimation and underestimation. RESULTS High inhaler adherence was reported both by patients (median (percentile 25 to percentile 75) 85 (65-95) mm; 53% VAS>80) and by physicians (84 (68-95) mm; 53% VAS>80). Correlation between patient and physician VAS scores was moderate (rs=0.580; p<0.001). Discordance occurred in 56% of cases: in 28% physicians overestimated adherence and in 27% underestimated. Low adherence as assessed by the physician (OR=27.35 (9.85 to 75.95)), FEV1 ≥80% (OR=2.59 (1.08 to 6.20)) and a first appointment (OR=5.63 (1.24 to 25.56)) were predictors of underestimation. An uncontrolled asthma (OR=2.33 (1.25 to 4.34)), uncontrolled upper airway disease (OR=2.86 (1.35 to 6.04)) and prescription of short-acting beta-agonists alone (OR=3.05 (1.15 to 8.08)) were associated with overestimation. Medium adherence as assessed by the physician was significantly associated with higher risk of discordance, both for overestimation and underestimation of adherence (OR=14.50 (6.04 to 34.81); OR=2.21 (1.07 to 4.58)), while having a written action plan decreased the likelihood of discordance (OR=0.25 (0.12 to 0.52); OR=0.41 (0.22 to 0.78)) (R2=44%). CONCLUSION Although both patients and physicians report high inhaler adherence, discordance occurred in half of cases. Implementation of objective adherence measures and effective communication are needed to improve patient-physician agreement.
