RESUMEN
In atherosclerotic lesions, vascular smooth muscle cells (VSMCs) represent half of the foam cell population, which is characterized by an aberrant accumulation of undigested lipids within lysosomes. Loss of lysosome function impacts VSMC homeostasis and disease progression. Understanding the molecular mechanisms underlying lysosome dysfunction in these cells is, therefore, crucial. We identify cholesteryl hemiazelate (ChA), a stable oxidation end-product of cholesteryl-polyunsaturated fatty acid esters, as an inducer of lysosome malfunction in VSMCs. ChA-treated VSMCs acquire a foam-cell-like phenotype, characterized by enlarged lysosomes full of ChA and neutral lipids. The lysosomes are perinuclear and exhibit degradative capacity and cargo exit defects. Lysosome luminal pH is also altered. Even though the transcriptional response machinery and autophagy are not activated by ChA, the addition of recombinant lysosomal acid lipase (LAL) is able to rescue lysosome dysfunction. ChA significantly affects VSMC proliferation and migration, impacting atherosclerosis. In summary, this work shows that ChA is sufficient to induce lysosomal dysfunction in VSMCs, that, in ChA-treated VSMCs, neither lysosome biogenesis nor autophagy are triggered, and, finally, that recombinant LAL can be a therapeutic approach for lysosomal dysfunction.

Alkaptonuria (AKU) is an ultra-rare disease caused by the deficient activity of homogentisate 1,2-dioxygenase enzyme, leading the accumulation of homogentisic acid (HGA) in connective tissues implicating the formation of a black pigmentation called "ochronosis." Although AKU is a multisystemic disease, the most affected tissue is the articular cartilage, which during the pathology appears to be highly damaged. In this study, a model of alkaptonuric chondrocytes and cartilage was realized to investigate the role of HGA in the alteration of the extracellular matrix (ECM). The AKU tissues lost its architecture composed of collagen, proteoglycans, and all the proteins that characterize the ECM. The cause of this alteration in AKU cartilage is attributed to a degeneration of the cytoskeletal network in chondrocytes caused by the accumulation of HGA. The three cytoskeletal proteins, actin, vimentin, and tubulin, were analyzed and a modification in their amount and disposition in AKU chondrocytes model was identified. Cytoskeleton is involved in many fundamental cellular processes; therefore, the aberration in this complex network is involved in the manifestation of AKU disease.

Hepatitis E in industrialized countries is mainly associated with genotype 3 hepatitis E virus (HEV) and normally causes a sporadic self-limiting disease in immunocompetent individuals. Unlike genotype 3, genotypes 1 and 2 circulate in developing countries, produce severe disease and occur in the epidemic form. Hepatitis E occurring in travellers returning from endemic areas in developing countries is not a novel epidemiological occurrence, however the vast majority of cases remain to be genetically studied. The present study describes two cases of severe acute hepatitis E that required hospitalization for 6 and 9 days in two individuals of Indian nationality that had recently migrated to Portugal to work. The retrieved HEV sequences both belonged to genotype 1 and had a high degree of nucleotide sequence identity, clustering with strains isolated in India and Nepal, in 2013 and 2014. Confirmed HEV genotypes of increased pathogenicity like genotype 1 are being introduced into otherwise naïve populations of industrialized countries such as European countries with consequences difficult to predict. As far as we know the present study is the first in Portugal to describe and genetically characterize imported cases of hepatitis E infection caused by HEV genotype 1.

PURPOSE: In this study, we aimed to understand whether glucose transporter 1 (GLUT1) activity affects the secretion capacity of antiangiogenic factor pigment epithelium-derived factor (PEDF) by the RPE cells, thus explaining the reduction in PEDF levels observed in patients with diabetic retinopathy (DR). METHODS: Analysis of GLUT1 expression, localization, and function was performed in vitro in RPE cells (D407) cultured with different glucose concentrations, corresponding to non-diabetic (5 mM of glucose) and diabetic (25 mM of glucose) conditions, further subjected to normoxia or hypoxia. The expression of PEDF was also evaluated in the secretome of the cells cultured in these conditions. Analysis of GLUT1 and PEDF expression was also performed in vivo in the RPE of Ins2(Akita) diabetic mice and age-matched wild-type (WT) controls. RESULTS: We observed an increase in GLUT1 under hypoxia in a glucose-dependent manner, which we found to be directly associated with the translocation and stabilization of GLUT1 in the cell membrane. This stabilization led to an increase in glucose uptake by RPE cells. This increase was followed by a decrease in PEDF expression in RPE cells cultured in conditions that simulated DR. Compared with non-diabetic WT mice, the RPE of Ins2(Akita) mice showed increased GLUT1 overexpression with a concomitant decrease in PEDF expression. CONCLUSIONS: Collectively, our data show that expression of GLUT1 is stimulated by hyperglycemia and low oxygen supply, and this overexpression was associated with increased activity of GLUT1 in the cell membrane that contributes to the impairment of the RPE secretory function of PEDF.

Background and Aim: Dobutamine stress echocardiography (DSE) is a well-established noninvasive investigation for significant coronary artery disease (CAD). The aim of this study was to evaluate the accuracy of cardiac Doppler parameters in predicting CAD. Methods: We prospectively studied 103 consecutive patients with suspected CAD based on typical symptoms; 59 proved to have CAD, and 44 patients proved to have no-CAD (n = 44). All patients underwent a complete stress Doppler echocardiographic examination. Total isovolumic time (T-IVT) as a marker of cavity dyssynchrony and wall motion score index (WMSI) were also calculated. Results: At peak dobutamine stress, the compromised LV longitudinal excursion (MAPSE), systolic septal and lateral velocities (s'), and diastolic indices were more pronounced in the CAD patients compared with those without CAD, but LV dimension did not differ between groups (p > 0.05). The WMSI was higher and t-IVT more prolonged in patients with CAD (p < 0.01 for both). Similarly, the changes were more pronounced in patients with significant CAD compared with insignificant CAD. On multivariate model, Δ mean s', OR 2.016 (1.610 to 3.190; p < 0.001), Δ E velocity OR 2.502 (1.179 to 1.108; p < 0.001), Δ t-IVT 2.206 (1.180 to 2.780; p < 0.001) and Δ WMSI OR 1.911 (1.401 to 3.001; p = 0.001) were the most powerful independent predictors of the presence of CAD, particularly when significant (>75%). Δ mean s' < 5.0 was 85% sensitive, 89% specific with AUC 0.92. Respective values for Δ E velocity <6.0 cm/s were 82%, 90% and 0.91; for Δ t-IVT > 4.5, 78%, 77% and 0.81 and for Δ FT ≥ 150 ms, 76%, 78% and 0.84 in predicating significant CAD. WMSI ≥ 0.7 was 75% sensitive, 77% specific with AUC of 0.81 in predicting significant CAD. The accuracy of DSE was higher in significant CAD compared to insignificant CAD (80% vs. 74%; p = 0.03). Conclusions: Compromised LV longitudinal systolic function, lower delta E wave, prolonged t-IVT, and increased WMSI were the most powerful independent predictors of the presence and significance of CAD. These finding strengthen the role of comprehensive DSE analysis in diagnosing ischemic disturbances secondary to significant CAD.
RESUMEN
Cryptococcal meningitis is a common opportunistic infection in HIV-infected patients and other immunocompromised people. Pregnancy, which is a state of relative immunosuppression, can also be a risk factor for the development of cryptococcal meningitis. We report a clinical case of a 41-year-old woman who developed a severe meningeal syndrome after an otherwise normal pregnancy. Cerebrospinal fluid (CSF) cytochemical analysis presented hypoglycorrhachia, high protein levels, and pleocytosis. Cryptococcal antigen tested positive in serum and CSF, and Cryptococcus neoformans was identified in the CSF culture. The diagnosis of cryptococcal meningitis was confirmed, and antifungal induction therapy was started with liposomal amphotericin B and flucytosine. After clinical improvement, induction therapy was discontinued, and the patient was discharged under maintenance therapy with fluconazole. While under antifungal maintenance therapy, the patient presented worsening of symptoms and a new brain magnetic resonance showed the development of multiple cryptococcoma. Despite sterile CSF cultures, there was a deterioration of the cytochemical parameters. The diagnosis of immune reconstitution inflammatory syndrome was assumed, and after initiation of corticotherapy, the patient improved considerably. This is a rare case of cryptococcal meningitis in a puerperal woman with a challenging management.
RESUMEN
BACKGROUND: Localized stress and cell death in chronic inflammatory diseases may release tissue-specific lipids into the circulation causing the blood plasma lipidome to reflect the type of inflammation. However, deep lipid profiles of major chronic inflammatory diseases have not been compared. METHODS: Plasma lipidomes of patients suffering from two etiologically distinct chronic inflammatory diseases, atherosclerosis-related vascular disease, including cardiovascular (CVD) and ischemic stroke (IS), and systemic lupus erythematosus (SLE), were screened by a top-down shotgun mass spectrometry-based analysis without liquid chromatographic separation and compared to each other and to age-matched controls. Lipid profiling of 596 lipids was performed on a cohort of 427 individuals. Machine learning classifiers based on the plasma lipidomes were used to distinguish the two chronic inflammatory diseases from each other and from the controls. FINDINGS: Analysis of the lipidomes enabled separation of the studied chronic inflammatory diseases from controls based on independent validation test set classification performance (CVD vs control - Sensitivity: 0.94, Specificity: 0.88; IS vs control - Sensitivity: 1.0, Specificity: 1.0; SLE vs control - Sensitivity: 1, Specificity: 0.93) and from each other (SLE vs CVD â Sensitivity: 0.91, Specificity: 1; IS vs SLE - Sensitivity: 1, Specificity: 0.82). Preliminary linear discriminant analysis plots using all data clearly separated the clinical groups from each other and from the controls, and partially separated CVD severities, as classified into five clinical groups. Dysregulated lipids are partially but not fully counterbalanced by statin treatment. INTERPRETATION: Dysregulation of the plasma lipidome is characteristic of chronic inflammatory diseases. Lipid profiling accurately identifies the diseases and in the case of CVD also identifies sub-classes. FUNDING: Full list of funding sources at the end of the manuscript.

Tuberculosis (TB) is one of the top 10 causes of death worldwide. Multidrug-resistant tuberculosis (MDR-TB) occurs when at the minimum there is resistance to isoniazid and rifampin. Prevention of new infections of Mycobacterium tuberculosis and progression to TB disease is critical to reduce the burden and mortality of this disease. We present the case of a 73-year-old human immunodeficiency virus (HIV)-negative female who presented with cervical lymphadenopathy and who was diagnosed with MDR-TB. LEARNING POINTS: Tuberculosis is one of the most important causes of morbidity and mortality worldwide and approximately a quarter of the world's population is estimated to be latently infected by Mycobacterium tuberculosis.Multidrug-resistant tuberculosis lymphadenitis is a rare manifestation of the disease in Portugal.With the advent of multidrug-resistant tuberculosis, disease surveillance by the government should be intensified, with the aim of national and global TB control, focusing on prevention.
RESUMEN
Environmental and/or work risk factors, lack of basic knowledge related to voice, its incorrect use, and a defective vocal model can lead teachers to develop occupational dysphonia. This study aimed to analyze studies focusing on occupational vocal disorders through a literature review. Articles published over a period of 11 years in periodicals indexed in the ScieLO library were searched according to predetermined inclusion and exclusion criteria. Twenty articles related to teachers' vocal occupational disorders were found. We argue that intense vocal use should not harm professionals; the voice has to be pleasant to the speaker and correctly produced. The conclusion is that there is a scarcity of articles available at the studied library relating to teachers' voice disorders. Further studies need to be developed and disseminated so as to increase knowledge in the subject.

Expressiveness is the ability of individuals to make their thoughts alive through language and body, effectively transmitting information. This study investigated the expressiveness of a university professor during nursing classes in relation to verbal resources from the perspective of students. This descriptive and quantitative study was carried out in a Higher Education Institution using specific instruments to assess expressiveness. The professor's class was video recorded and the video was first assessed by three speech and language experts and later assessed by 141 students with whom he had no previous contact. The results reveal that students and experts agreed in relation to the professors' expressive skills, which proved the ability of students to evaluate this communication skill.

Riscos ocupacionais psicossociais (ROP) são constituídos por um conjunto de fatores que alteram o bem-estar emocional dos trabalhadores. Objetivou-se identificar a existência de ROP no ambiente laboral de professores universitários e suas repercussões na saúde destes trabalhadores. Trata-se de um estudo transversal, descritivo e quantitativo, com dados coletados, em 2006, em uma universidade pública paulista. Constituíram-se sujeitos 54 docentes que responderam a um questionário com dados sociodemográficos, questões sobre as condições de trabalho, os ROP e suas repercussões em sua saúde. Os resultados evidenciaram que 51(94,4%) docentes admitiram a presença de ROP no trabalho, predominando a carga mental em 19(35%) sujeitos; 47(87%) admitiram que tais riscos afetavam a sua saúde, destacando-se o estresse apontado por 21(38,9%) sujeitos e a ansiedade por 9(16,7%) deles. Concluiu-se que os ROP estavam presentes no contexto acadêmico avaliado e foram percebidos como influenciadores na saúde destes docentes.
Psychosocial occupational risks (POR) are integrated by a set of factors that affect the emotional well-being of workers. We aimed at identifying POR on the work environment of professors of a public university and its impact on the health of those workers. This is a cross-sectional, descriptive, and quantitative study conducted in 2006 at a public university in the state of São Paulo, Brazil. Fifty-four subjects were constituted out of the professors, who answered a questionnaire including demographic data, working conditions, POR, and POR impact on their health. Results showed that 51(94.4%) professors identified POR at work, with mental load in 19(35%) subjects; 47(87%) professors reported that such risks affect their health, with stress mentioned by 21(38.9%) professors and anxiety by 9(16.7%). Conclusions show the presence of POR in the academic context assessed and the perception of their impact on the health of those professors.

O estudo objetivou avaliar a incidência e intensidade de dor músculo-esquelética nos membros inferiores de costureiros industriais. Realizou-se pesquisa de campo e exploratória em uma cooperativa de costura de roupas esportivas, na cidade de Rifaina (SP), em janeiro e fevereiro de 2004, analisando-se 34 trabalhadores, a maioria do sexo feminino. Elaborou-se um questionário que abordava os aspectos pessoais, organizacionais e sintomatológicos e um protocolo que identificava os movimentos e posturas empregados durante a atividade, constando os principais movimentos articulares e faixas de amplitude do movimento, considerados de risco para o desenvolvimento de lesões. Os resultados mostraram que os trabalhadores apresentaram alta incidência e intensidade de dor, e as diferentes atividades foram igualmente lesivas devido ao posicionamento estático associado a amplitudes de risco. Concluiu-se que as situações identificadas mostraram-se como risco no ambiente de trabalho, tendo este fato sido corroborado pelo relato dos trabalhadores com relação às dores por eles percebidas.
The study evaluated the incidence and intensity of lower member musculoskeletal pain in industrial dressmakers. An exploratory field study conducted in January and February 2004 in a sports garment sewing cooperative in Rifaina, São Paulo State - Brazil, examined 34, mostly female, workers by applying a questionnaire to record personal, organizational and symptomatologic particulars and a protocol to identify the movements and postures used during the activity, record the main joint movements and ranges of movement considered as risks for developing injuries. The results showed high incidence and intensity of pain and that the various different activities were detrimental because of static positioning associated with risk-related ranges of movement. It was concluded that the situations identified were sources of workplace risk, which was corroborated by the workers reports of the pain they felt.

This descriptive study, conducted at a teaching hospital in São Paulo in 2000, used patient file data from a hospital emergency unit to characterize occupational accidents (OAs) suffered by elderly people. Data were collected using documentary analysis of records of care given in 1998 and 1999. Of 618 OAs, 21.84% related to elderly; 45.93% of these people were 60 to 69 years old, 26.67% were retired, 68.89% of OAs involved falls; 34.81% affected lower limbs and 55.56% resulted in fractures. Elderly have been suffering OAs, showing they re-enter the labor market after retirement.
