Influence of Clinical and Psychosocial Factors on the Adherence to Topical Treatment in Psoriasis.

(1) Background: Psoriasis is a common chronic inflammatory skin disease with different manifestations, affecting the quality of life at social, emotional, and professional dimensions and requiring long-term treatment. This study aimed to investigate the effect of psychosocial and clinical factors on adherence to topical treatment in psoriasis. (2) Methods: Self-reported measures and weighing the medicines were used to assess adherence. Psychopathological symptoms were measured using the Brief Symptoms Inventory (BSI). Social and clinical factors were assessed by a sociodemographic and clinical questionnaire. Adherence to treatment with topical medication was assessed using a sample of 102 psoriasis patients. (3) Results: The explanatory models of adherence to topical treatment in psoriasis translated into positive associations between adherence and the education level (higher education) (p = 0.03; φ = 0.23), the single-family household (p = 0.01; φ = 0.44), active employment status (p = 0.05; φ = -0.19), familiar history of psoriasis (p = 0.04; φ = -0.21), and the presence of obsessive-compulsive symptoms (p = 0.01; d = 0.29). (4) Conclusions: In patients who present the characteristics identified that influence non-adherence, instructions should be reinforced to increase adherence. The experimental mortality (39.6%) reduced the sample size, representing a limitation of the study.

Lung Injury Risk in Traumatic Brain Injury Managed With Optimal Cerebral Perfusion Pressure Guided-Therapy.

Introduction: Management of traumatic brain injury (TBI) has to counterbalance prevention of secondary brain injury without systemic complications, namely lung injury. The potential risk of developing acute respiratory distress syndrome (ARDS) leads to therapeutic decisions such as fluid balance restriction, high PEEP and other lung protective measures, that may conflict with neurologic outcome. In fact, low cerebral perfusion pressure (CPP) may induce secondary ischemic injury and mortality, but disproportionate high CPP may also increase morbidity and worse lung compliance and hypoxia with the risk of developing ARDS and fatal outcome. The evaluation of cerebral autoregulation at bedside and individualized (optimal CPP) CPPopt-guided therapy, may not only be a relevant measure to protect the brain, but also a safe measure to avoid systemic complications. Aim of the study: We aimed to study the safety of CPPopt-guided-therapy and the risk of secondary lung injury association with bad outcome. Methods and results: Single-center retrospective analysis of 92 severe TBI patients admitted to the Neurocritical Care Unit managed with CPPopt-guided-therapy by PRx (pressure reactivity index). During the first 10 days, we collected data from blood gas, ventilation and brain variables. Evolution along time was analyzed using linear mixed-effects regression models. 86% were male with mean age 53±21 years. 49% presented multiple trauma and 21% thoracic trauma. At hospital admission, median GCS was 7 and after 3-months GOS was 3. Monitoring data was CPP 86±7mmHg, CPP-CPPopt -2.8±10.2mmHg and PRx 0.03±0.19. The average PFratio (PaO2/FiO2) was 305±88 and driving pressure 15.9±3.5cmH2O. PFratio exhibited a significant quadratic dependence across time and PRx and driving pressure presented significant negative association with PFRatio. CPP and CPPopt did not present significant effect on PFratio (p=0.533; p=0.556). A significant positive association between outcome and the difference CPP-CPPopt was found. Conclusion: Management of TBI using CPPopt-guided-therapy was associated with better outcome and seems to be safe regarding the development of secondary lung injury.

Anxiety and Depression Symptoms During the COVID-19 Pandemic: A Cluster Analysis of Individuals Living in Portugal.

INTRODUCTION: The COVID-19 pandemic is an illustration of how a physical illness can damage people's minds. In this regard, the goal of this study was to see how different sociodemographic and behavioral factors were linked to anxiety and depression symptoms in a group of individuals living in Portugal. METHODS: Between November 2020 and February 2021, a cross-sectional, snowball online study was conducted. The study's target population was adults over the age of 18, residents of the country. For the statistical analysis, the clustering technique - K-means algorithm was applied. The chi-squared test was used to determine the relationships between clusters and sociodemographic and behavioral characteristics. Statistical analyses were conducted in R language, with a significance level of 0.05. A total of 453 participants were included. RESULTS: The majority were female (69.8%), under the age of 40 (60.8%), with a higher education degree (75.3%), and not married (54.4%). Furthermore, the majority were from the country's north region (66%). Cluster 1 (n = 194) was characterized by low or nonexistent levels of anxiety and depression symptoms, which means normal; cluster 2 by severe symptoms (n = 82), meaning case; and cluster 3 by mild symptoms (n = 177), which means borderline. Younger participants (p-value 0.024), female (p-value 0.041), with drinking habits (p-value 0.002), food insecurity (p-value < 0.001), food affordability exacerbation (p-value < 0.001), comorbidity (p-value < 0.001), use of anxiolytics (p-value < 0.001), insufficient household income (p-value 0.017) and income change (p-value < 0.001) were significantly associated with the anxiety-depression clusters. From the three clusters, cluster 2 was mainly represented by younger participants, with more persons stating that their household income was insufficient and that their income has changed as a result of COVID-19 and that they had the highest probability of food insecurity. CONCLUSION: The impacts of a crisis on mental health extend longer than the event itself. We were able to observe that younger women with insufficient household income who suffered a change in income due to COVID-19 and were classified as food insecure presented higher levels of anxiety and depression symptoms. These results highlight the presence of a social gradient where we saw that people who were less advantaged in terms of socioeconomic position presented worse mental health outcomes, stressing, in this sense, the need to bring the best public health responses for these specific groups of the population.

FRAX 10-year fracture risk in rheumatoid arthritis assessed with and without bone mineral density - are we treating our patients under bDMARDs?

OBJECTIVE: This study aimed to identify the rheumatoid arthritis (RA) patients under biological therapy who have FRAX® scores classified as high fracture risk and to evaluate if they are receiving treatment for osteoporosis (OP). The authors also investigated the intra-individual agreement between FRAX® fracture risk calculated with and without bone mineral density (BMD). METHODS: A single-center retrospective cohort study was performed in a total of 303 patients with RA under biologics. Demographic and clinical data were collected using Rheumatic Diseases Portuguese Register (Reuma.pt), complemented with data from the hospital clinical records. FRAX scores with and without BMD were calculated. The Kendall's Tau coefficient was used to assess the agreement between FRAX risk categories. Correlations were evaluated by the Spearman test. Comparisons of distributions from independent variables used the Mann-Whitney test. RESULTS: When FRAX® score was calculated without BMD (n=303), 25% patients were categorized as high fracture risk. Among them, only 54% were receiving OP treatment. FRAX® assessment with BMD (n=231) identified 33% patients with high fracture risk, 52% in treatment for OP. Thirty patients (21%) previously classified as low fracture risk using FRAX® without BMD were recategorized as high risk (𝜏=0.570, p.

Influence of psoriasis lesions' location and severity on psychosocial disability and psychopathology. Observational study and psychometric validation of the SAPASI Portuguese version.

OBJECTIVES: The psychosocial impact of psoriasis is well documented. However, the contributing role of clinical disease characteristics is not satisfactorily explored. This study aimed to validate the Self-administered Psoriasis Area and Severity Index (SAPASI) to a Portuguese population (SAPASI-PT) and to perform its cross-validation, assessing how the results will generalize to an independent data set, with the Psoriasis Area and Severity Index (PASI), in order to assess the influence of psoriasis' severity on psychosocial disability and psychopathology. METHODS: A cross-sectional study with 228 patients with psoriasis was carried out. Data was collected through a sociodemographic and clinical questionnaire, SAPASI-PT, the Psoriasis Disability Index (PDI) and the Brief Symptoms Inventory (BSI). The cultural and linguistic adaptation of SAPASI to a Portuguese version and the cross validation with PASI was carried out. Multiple associations between psychosocial disability, psychopathology and severity, discomfort and location of lesions were investigated through logistic regression models. RESULTS: A good adjustment model for SAPASI-PT is found. Also, associations between psychosocial disability, psychopathology and the psoriasis severity and discomfort are found. The existence of lesions is positively associated with the severity of the disease. Patients with lesions in hands or genitals are those reporting a greater discomfort. The presence of lesions in hands is positively associated with PDI, i.e., with leisure and with treatment, marginally. Additionally, patients scoring higher in the personal dimension are found to have a significantly greater percentage of lesions in the genitals. CONCLUSIONS: The psoriasis severity and location of lesions are important determinants of patients´ quality of life. Lesions on face, hands and genitals are associated with a higher impact on psychosocial wellbeing of patients. Psychological counselling should be considered within psoriasis treatment context in patients with the described disease manifestations.

Does the Vehicle Matter? Real-World Evidence on Adherence to Topical Treatment in Psoriasis.

The influence of the vehicle in topical treatment adherence remains to be elucidated. The aim of this study is to analyze the influence of the pharmaceutical dosage form on adherence to topical treatment in psoriasis patients, taking into consideration the mechanical features. The adherence was evaluated in a sample of 102 psoriasis patients, followed for approximately 45 days. Adherence was calculated with a new combined methodology using a log and medication weights. The effect of the group formulation was evaluated using logistic regression models. A complex effect of the vehicle on adherence was found, mediated by the affected area. The adherence was significantly higher for patients applying gels and creams than for those using ointments, whenever the body area affected was extensive. The opposite was found when the affected area was small. Mechanical properties can partially explain the findings since gels and creams may be easier to apply. Patient beliefs and preferences regarding vehicles and their sensory attributes might also explain the results. It is noteworthy that adherence was strikingly low, with more than 75% non-adherent patients. This real-world evidence provides an insight for pharmaceutical industries and guidance for treatment prescription by physicians aiming to address the public health emergency of treatment non-adherence.

Evaluation of drug-resistant tuberculosis treatment outcome in Portugal, 2000-2016.

Treatment of drug-resistant tuberculosis (TB), which is usually less successful than that of drug-susceptible TB, represents a challenge for TB control and elimination. We aimed to evaluate treatment outcomes and to identify the factors associated with death among patients with MDR and XDR-TB in Portugal. We assessed MDR-TB cases reported for the period 2000-2016, using the national TB Surveillance System. Treatment outcomes were defined according to WHO recommendations. We identified the factors associated with death using logistic regression. We evaluated treatment outcomes of 294 MDR- and 142 XDR-TB patients. The treatment success rate was 73.8% among MDR- and 62.7% among XDR-TB patients (p = 0.023). The case-fatality rate was 18.4% among MDR- and 23.9% among XDR-TB patients. HIV infection (OR 4.55; 95% CI 2.31-8.99; p < 0.001) and resistance to one or more second-line injectable drugs (OR 2.73; 95% CI 1.26-5.92; p = 0.011) were independently associated with death among MDR-TB patients. HIV infection, injectable drug use, past imprisonment, comorbidities, and alcohol abuse are conditions that were associated with death early on and during treatment. Early diagnosis of MDR-TB and further monitoring of these patients are necessary to improve treatment outcome.

Peripheral arterial tonometry as a method of measuring reactive hyperaemia correlates with organ dysfunction and prognosis in the critically ill patient: a prospective observational study.

Predictions of mortality may help in the selection of patients who benefit from intensive care. Endothelial dysfunction is partially responsible for many of the organic dysfunctions in critical illness. Reactive hyperaemia is a vascular response of the endothelium that can be measured by peripheral arterial tonometry (RH-PAT). We aimed to assess if reactive hyperaemia is affected by critical illness and if it correlates with outcomes. Prospective study with a cohort of consecutive patients admitted to an Intensive Care Unit. RH-PAT was accessed on admission and on the 7th day after admission. Early and late survivors were compared to non-survivors. The effect of RH-PAT variation on late mortality was studied by a logistic regression model. The association between RH-PAT and severity scores and biomarkers of organic dysfunction was investigated by multivariate analysis. 86 patients were enrolled. Mean ln(RHI) on admission was 0.580 and was significantly lower in patients with higher severity scores (p < 0.01) and early non-survivors (0.388; p = 0.027). The model for prediction of early-mortality estimated that each 0.1 decrease in ln(RHI) increased the odds for mortality by 13%. In 39 patients, a 2nd RH-PAT measurement was performed on the 7th day. The variation of ln(RHI) was significantly different between non-survivors and survivors (- 24.2% vs. 63.9%, p = 0.026). Ln(RHI) was significantly lower in patients with renal and cardiovascular dysfunction (p < 0.01). RH-PAT is correlated with disease severity and seems to be an independent marker of early mortality, cardiovascular and renal dysfunctions. RH-PAT variation predicts late mortality. There appears to be an RH-PAT impairment in the acute phase of severe diseases that may be reversible and associated with better outcomes.

Transcranial Doppler-derived indices of cerebrovascular haemodynamics are independent of depth and angle of insonation.

Continuous measurement of cerebral blood flow velocity (CBFV) of the middle cerebral artery (MCA) using transcranial Doppler (TCD) and arterial blood pressure (ABP) monitoring enables assessment of cerebrovascular haemodynamics. Further indices describing cerebrovascular function can be calculated from ABP and CBFV, such as the mean index (Mxa) of cerebrovascular autoregulation, the 'time constant of the cerebral arterial bed' (tau), the 'critical closing pressure' (CrCP) and a 'non-invasive estimator of ICP' (nICP). However, TCD is operator-dependent and changes in angle and depth of MCA insonation result in different readings of CBFV. The effect of differing CBFV readings on the calculated secondary indices remains unknown. The aim of this study was to investigate variation in angle and depth of MCA insonation on these secondary indices. In eight patients continuous ABP and ipsilateral CBFV monitoring was performed using two different TCD probes, resulting in four simultaneous CBFV readings at different angles and depths per patient. From all individual recordings, the K-means clustering algorithm was applied to the four simultaneous longitudinal measurements. The average ratios of the between-clusters, sum-of-squares and total sum-of-squares were significantly higher for CBFV than for the indices Mxa, tau and CrCP (p < 0.001, p = 0.007 and p = 0.016) but not for nICP (p = 0.175). The results indicate that Mxa, tau and CrCP seemed to be not affected by depth and angle of TCD insonation, whereas nICP was.

Reactive hyperemia correlates with the presence of sepsis and glycocalyx degradation in the intensive care unit: a prospective cohort study. / A hiperemia reativa correlaciona-se com presença de sepse e degradação de glicocálix na unidade de terapia intensiva: um estudo de coorte prospectiva.

OBJECTIVE: To investigate whether reactive hyperemia measured by peripheral arterial tonometry correlates with markers of endothelial dysfunction and may be used to identify sepsis in critical illness. METHODS: A prospective study was performed using a cohort of critically ill patients. Endothelial dysfunction was assessed on admission by quantifying reactive hyperemia-peripheral arterial tonometry and plasma levels of endothelin-1, soluble E-selectin, endocan and syndecan-1. Septic patients were compared to patients without evidence of infection. RESULTS: Fifty-eight septic patients were compared to 28 controls. The natural logarithm of reactive hyperemia-peripheral arterial tonometry was negatively correlated with cardiovascular comorbidities, disease severity and plasma levels of soluble E-selectin (p = 0.024) and syndecan-1 (p < 0.001). The natural logarithm of reactive hyperemia-peripheral arterial tonometry was lower in septic patients than in controls (0.53 ± 0.48 versus 0.69 ± 0.42, respectively). When adjusted for age, the multivariable model predicted that each 0.1-unit decrease in natural logarithm of reactive hyperemia-peripheral arterial tonometry increased the odds for infection by 14.6%. m. CONCLUSION: Reactive hyperemia-peripheral arterial tonometry is closely related to soluble E-selectin and syndecan-1, suggesting an association between endothelial activation, glycocalyx degradation and vascular reactivity. Reactive hyperemia-peripheral arterial tonometry appears to be compromised in critically ill patients, especially those with sepsis.

OBJETIVO: Investigar se a hiperemia reativa correlaciona-se com marcadores de disfunção endotelial e pode ser utilizada para identificar sepse na doença crítica. MÉTODOS: Trata-se de estudo prospectivo em uma coorte de pacientes críticos. A disfunção endotelial foi avaliada quando da admissão, por meio da quantificação de hiperemia por tonometria arterial periférica e níveis plasmáticos de endotelina 1, E-selectina solúvel, endocana e sindecano 1. Os pacientes sépticos foram comparados com pacientes sem evidência de infecção. RESULTADOS: Cinquenta e oito pacientes sépticos foram comparados com 28 controle. O logaritmo natural da tonometria arterial periférica teve correlação negativa com comorbidades cardiovasculares, severidade da doença e níveis plasmáticos de E-selectina solúvel (p = 0,024) e sindecano 1 (p < 0,001). O logaritmo natural da tonometria arterial periférica foi mais baixo nos pacientes sépticos quando comparado com os de pacientes controle (0,53 ± 0,48 versus 0,69 ± 0,42, respectivamente) e, quando ajustado à idade, o modelo multivariado predisse que cada 0,1 de diminuição em unidades de logaritmo natural da tonometria arterial periférica levou a aumento de 14,6% na probabilidade de infecção. CONCLUSÃO: A hiperemia reativa avaliada por tonometria arterial periférica tem estreita relação com E-selectina solúvel e sindecano 1, o que sugere associação entre ativação endotelial, degradação de glicocálix e reatividade vascular. A hiperemia reativa por tonometria arterial periférica parece estar comprometida em pacientes críticos, especialmente os com sepse.

A nationwide study of multidrug-resistant tuberculosis in Portugal 2014-2017 using epidemiological and molecular clustering analyses.

BACKGROUND: Increasing multidrug-resistant tuberculosis (MDR-TB) incidence is a major threat against TB eradication worldwide. We aim to conduct a detailed MDR-TB study in Portugal, an European country with endemic TB, combining genetic analysis and epidemiological data, in order to assess the efficiency of public health containment of MRD-TB in the country. METHODS: We used published MIRU-VNTR data, that we reanalysed using a phylogenetic analysis to better describe MDR-TB cases transmission occurring in Portugal from 2014 to 2017, further enriched with epidemiological data of these cases. RESULTS: We show an MDR-TB transmission scenario, where MDR strains likely arose and are transmitted within local chains. 63% of strains were clustered, suggesting high primary transmission (estimated as 50% using MIRU-VNTR data and 15% considering epidemiological links). These values are higher than those observed across Europe and even for sensitive strains in Portugal using similar methodologies. MDR-TB cases are associated with individuals born in Portugal and evolutionary analysis suggests a local evolution of strains. Consistently the sublineage LAM, the most common in sensitive strains in Europe, is the more frequent in Portugal in contrast with the remaining European MDR-TB picture where immigrant-associated Beijing strains are more common. CONCLUSIONS: Despite efforts to track and contain MDR-TB strains in Portugal, their transmission patterns are still as uncontrolled as that of sensitive strains, stressing the need to reinforce surveillance and containment strategies.

Baroreflex Impairment After Subarachnoid Hemorrhage Is Associated With Unfavorable Outcome.

BACKGROUND AND PURPOSE: Aneurysmal subarachnoid hemorrhage (SAH) is characterized by important changes in the autonomic nervous system with potentially adverse consequences. The baroreflex has a key role in regulating the autonomic nervous system. Its role in SAH outcome is not known. The purpose of this study was to evaluate the association between the baroreflex and the functional 3-month outcome in SAH. METHODS: The study used a prospective database of 101 patients hospitalized for SAH. We excluded patients receiving ß-blockers or noradrenaline. Baroreflex sensitivity (BRS) was measured using the cross-correlation method. A good outcome was defined by a Glasgow Outcome Scale score at 4 or 5 at 3 months. RESULTS: Forty-eight patients were included. Median age was 58 years old (36-76 years); women/men: 34/14. The World Federation of Neurosurgery clinical severity score on admission was 1 or 2 for 73% of patients. In the univariate analysis, BRS (P=0.007), sedation (P=0.001), World Federation of Neurosurgery score (P=0.001), Glasgow score (P=0.002), Fisher score (P=0.022), and heart rate (P=0.037) were associated with outcome. The area under the receiver operating characteristic curve for the model with BRS as a single predictor was estimated at 0.835. For each unit increase in BRS, the odds for a good outcome were predicted to increase by 31%. Area under the receiver operating characteristic curve for heart rate alone was 0.670. In the multivariate analysis, BRS (odds ratio, 1.312; 95% confidence interval, 1.048-1.818; P=0.018) and World Federation of Neurosurgery (odds ratio, 0.382; 95% confidence interval, 0.171-0.706; P=0.001) were significantly associated with outcome. Area under the receiver operating characteristic curve was estimated at 0.900. CONCLUSIONS: In SAH, early BRS was associated with 3-month outcome. This conclusion requires confirmation on a larger number of patients in a multicentre study.

Conventional versus pigtail chest tube-are they similar for treatment of malignant pleural effusions?

INTRODUCTION: The optimal chest tube type and size for drainage and chemical pleurodesis of malignant pleural effusions remains controversial. This retrospective study was conducted to compare the efficacy of conventional versus pigtail chest tube in the treatment of malignant pleural effusions. METHODS: Patients submitted to chest tube drainage and slurry talc pleurodesis due to malignant pleural effusion in our pulmonology ward from 2012 to 2016 were eligible. According to the type of chest tube, they were divided into two groups: group I-conventional chest tube and group II-pigtail chest tube. Number of deaths, recurrence of malignant pleural effusion, and timelines associated with the procedures were reviewed and compared between groups. RESULTS: Out of the 61 included patients, 46 (75.4%) were included in group I and 15 (24.6%) in group II. Only one patient had pigtail chest tube obstruction, with posterior insertion of conventional chest tube. Death during hospital stay and up to 3 months, recurrence at 4 weeks, total duration of hospital stay, time from chest tube insertion to pleurodesis, and time from chest tube insertion to removal were not significantly different between the two groups (all p > 0.05). DISCUSSION: These findings suggest that pigtail chest tube can be an alternative on palliation, with no compromise in pleurodesis performance.

Migration Flow and Its Impact on Tuberculosis Notification in Portugal / El flujo de migratorio y su impacto en la notificación de tuberculosis en Portugal

Introduction: Tuberculosis notification in Portugal has decreased in the last few years. As a consequence of the economic crisis, emigration has increased and immigration has decreased. Immigrants are a risk group for tuberculosis. Most emigrants are 20-44 years old and belong to the age group most affected by tuberculosis. Objective: To describe the decrease in tuberculosis notification in Portugal over the last years from a demographical point of view. Methods: Mathematical analysis was performed to quantify the effect of the migration movements (separately and simultaneously) on tuberculosis notification in Portugal from 2008 to 2014. We calculated the estimated tuberculosis notification for each year during the period of study: 1) fixing immigration rate and tuberculosis rate in immigrants at 2008 values; 2) fixing emigration rate and tuberculosis rate in emigrants at 2008 values; 3) fixing both phenomenons at 2008 values. Results: The differences between the observed and the estimated numbers were small (≤0.5 cases/100. 000 inhabitants). Discussion: Impact of the migration movements on tuberculosis notification rate does not seem to be significant when analyzed for each phenomenon individually and simultaneously, by our model. This might mean that we have to concentrate our efforts in other risk factors for tuberculosis (AU)

Introducción: La notificación de casos de tuberculosis en Portugal ha disminuido en los últimos años. Como consecuencia de la crisis económica, la emigración ha aumentado y la inmigración ha disminuido. Los inmigrantes son un grupo de riesgo para la tuberculosis. La mayoría de los emigrantes tienen entre 20 y 44 años y pertenecen al grupo de edad más afectado por la tuberculosis. Objetivo: Describir la disminución de la notificación de casos tuberculosis en Portugal en los últimos años, desde un punto de vista demográfico. Métodos: Se realizó un análisis matemático para cuantificar el efecto de los movimientos migratorios (por separado y simultáneamente) en la notificación de casos de tuberculosis en Portugal de 2008 a 2014. Se calculó la notificación de casos de tuberculosis estimada para cada año durante el período de estudio. La notificación estimada de tuberculosis para cada año del periodo de estudio se calculó: 1) fijando las tasas de inmigración y de tuberculosis en inmigrantes con datos del año 2008; 2) fijando las tasas de emigración y de tuberculosis en emigrantes con datos del año 2008, y 3) fijando ambos fenómenos con datos del año 2008. Resultados: Las diferencias entre los valores observados y los valores estimados fueron pequeñas (≤ 0,5 casos/100.000 habitantes). Discusión: Según el modelo matemático propuesto en este trabajo, el impacto de los movimientos migratorios en la tasa de notificación de casos de tuberculosis en Portugal no parece ser significativo cuando se analiza cada fenómeno tanto individual como simultáneamente. Estos datos indicarían que deberíamos concentrar los esfuerzos en identificar otros factores de riesgo para la tuberculosis (AU)
