Abstract
The elemental composition of chemical elements can vary between healthy and diseased tissues, providing essential insights into metabolic processes in physiological and diseased states. This study aimed to evaluate the calcium (Ca) and phosphorus (P) levels in the bones of rats with/without streptozotocin-induced diabetes and/or exposure to infrasound. X-ray fluorescence spectroscopy was used to determine the concentrations of Ca and P in Wistar rat tibiae samples.The results showed a significant decrease in bone P concentration in streptozotocin-induced diabetic rats compared to untreated animals. Similarly, the Ca/P ratio was higher in the streptozotocin-induced diabetic group. No significant differences were observed in bone Ca concentration between the studied groups or between animals exposed and not exposed to infrasound.Moreover, streptozotocin-induced diabetic rats had lower bone P concentration but unaltered bone Ca concentration compared to untreated rats. Infrasound exposure did not impact bone Ca or P levels. The reduced bone P concentration may be associated with an increased risk of bone fractures in diabetes.

Abstract
Mechanical prosthetic valve thrombosis (PVT) and obstruction are rare and dangerous events often related to inappropriate anticoagulant therapy. High mortality rates occur because of delayed diagnosis, hemodynamic instability, multiple organ failure (MOF), and high perioperative risk. Surgical repair is a first-line treatment for obstructive PVT with hemodynamic instability but is often not readily available or safely performed. Venoarterial extracorporeal membrane oxygenation (VA ECMO) support has been increasingly used in patients with PVT and cardiorespiratory collapse, allowing MOF reversal and safer deferred surgery. The authors present a case of a young female with refractory cardiogenic shock secondary to mitral PVT successfully managed with VA ECMO. Furthermore, the promising role of perioperative VA ECMO support for PVT-related cardiogenic shock is also discussed.

Abstract
Summary We report a 61-year-old male patient without personal history of thyroid carcinoma or radiation exposure. In 2011, he presented with a cervical mass whose biopsy diagnosed a papillary thyroid carcinoma (PTC) in a lymph node metastasis (LNM). Total thyroidectomy with lymphadenectomy of central and ipsilateral compartment was performed. Histopathology identified a 2 mm follicular variant of PTC and LNM in 25/25 lymph nodes. The patient was treated with 150 mCi of radioactive iodine (RAI), followed by levothyroxine suppressive therapy. In 2016, a retrotracheal mass was diagnosed, suggesting local recurrence; patient was submitted to surgical excision and RAI therapy (120 mCi). Due to seizures, in 2019, a brain CT was performed that diagnosed brain metastases. The patient underwent debulking of the main lesion. Histopathology analysis confirmed a metastatic lesion with variated morphology: classical PTC and follicular pattern and hobnail and tall cell features. Molecular analysis revealed BRAFV600E in LNM at presentation and BRAFV600E and TERT promoter (TERTp) mutations in the recurrent LNM and brain metastasis. Based upon this experience we review the reported cases of subcentimetric PTC with brain metastases and discuss the molecular progression of the present case. Learning points Papillary microcarcinoma (PMCs) usually have very good prognosis with low impact on patient survival. PMCs presenting in elderly patients with LNM at diagnosis may carry a guarded outcome. Brain metastasis although rare indicate aggressive phenotypic features. Patient risk stratification of PMCs based on histopathological analysis and genetic testing may have a significant impact on prognosis providing therapeutic markers, that may predict disease progression and overall outcome.

Abstract
INTRODUCTION Men born with pathogenic/likely pathogenic variants in genes associated with the Hereditary Breast and Ovarian Cancer Syndrome have a higher risk to develop breast cancer and other cancers (such as prostate cancer) and should undergo adequate surveillance protocols in highly specialized Centers. METHODS A retrospective study was conducted to assess these genetic variants' epidemiological and phenotypical manifestations in male carriers, as well as the efficacy of the surveillance protocol and compliance toward it through a survey. During follow-up, a genetic panel for testing was implemented, the starting age for surveillance was delayed, and the six-month screening interval was extended to annual. RESULTS A total of 104 men from a tertiary hospital's High-Risk Consultation were included, 102 with positive genetic testing for BRCA1 (n = 31), BRCA2 (n = 55), both BRCA2 and another gene (n = 5), CDH1 (n = 2), CHEK2 (n = 4), NF1 (n = 1), RAD51C (n = 4), and an additional two men with no actionable genetic variant identified. The follow-up period ranged from 1 to 13 years, and only one man developed cancer. Survey responses from 48 men in active surveillance showed that more than half recognizes their carrier status and consequent surveillance impact on their life, including the risk of transmission to offspring, fear of future cancer, meaningful distress, and feeling of injustice. Biannual surveillance was not actively detecting more cancer disease cases, confirming the adequacy of the currently implemented protocol CONCLUSION: With support of Genetics to fulfill the current gaps in high-risk management, the proposed redefinition of surveillance protocol would adapt it to the population needs and concerns.

Abstract
Early and accurate detection of infection by pathogenic microorganisms, such as Plasmodium, the causative agent of malaria, is critical for clinical diagnosis and ultimately determines the patient's outcome. We have combined a polystyrene-based microfluidic device with an immunoassay which utilises Surface-Enhanced Raman Spectroscopy (SERS) to detect malaria. The method can be easily translated to a point-of-care testing format and shows excellent sensitivity and specificity, when compared to the gold standard for laboratorial detection of Plasmodium infections. The device can be fabricated in less than 30 min by direct patterning on shrinkable polystyrene sheets of adaptable three-dimensional microfluidic chips. To validate the microfluidic system, samples of P. falciparum-infected red blood cell cultures were used. The SERS-based immunoassay enabled the detection of 0.0012 ± 0.0001% parasitaemia in a P. falciparum-infected red blood cell culture supernatant, an ∼7-fold higher sensitivity than that attained by most rapid diagnostic tests. Our approach successfully overcomes the main challenges of the current Plasmodium detection methods, including increased reproducibility, sensitivity, and specificity. Furthermore, our system can be easily adapted for detection of other pathogens and has excellent properties for early diagnosis of infectious diseases, a decisive step towards lowering their high burden on healthcare systems worldwide.

Abstract
AIMS To characterize a cohort of T1D patients and to compare diabetes control between patients using different regimen of insulin therapy and glucose monitoring. METHODS Were included all T1D patients followed at the Pediatric Endocrinology Unit, between April 1st and June 30th, 2021. Several clinical and demographic variables were analyzed. RESULTS Our sample included 208 patients, 56.7 % males, mean age of 12.7 ± 4.6 years. The median HbA1c was 7.3 %. Most patients, 78.8% were treated with continuous subcutaneous insulin infusion (CSII) and 81.3 % used continuous glucose monitoring (CGM). CSII had a lower HbAc compared with multiple daily injections (MDI) users (7.1vs 8.1 %, p < 0.01). In the CSII group, those who used CGM had a lower HbAc (7.1 vs 7.5 %,p = 0.02). Analyzing the data of the ambulatory glucose report, the CSII users had a lower glucose management indicator, (7.2 % vs 7.6 %, p < 0.01), more time in range (58.0 % vs 52.4 %;p < 0.01) and less time above range > 250 mg/dL (12.4 % vs 20.5 %;p < 0.01) than MDI users. CONCLUSIONS The median HbA1c was 7.3% very close to the recommended target. In Portugal, pediatric patients can access a CSII provided by the national health service and a CGM system due to an elevated reimbursement of their cost. This healthy policy allows us to achieve better goals without the risk of hypoglycemia.

Abstract
Background and objective Pediatric thyroid disease requiring surgery is rare. Thyroid nodules are a frequent indication for surgery and are mostly benign. However, up to 25% of cases can be malignant. In this study, we aimed to describe our center's experience with regard to pediatric thyroid surgery. Methods This was a retrospective transverse study involving pediatric patients who underwent thyroid surgery at a tertiary hospital between January 2010 and December 2021. Results A total of 14 patients underwent 15 surgeries. The main reason for referral to pediatric endocrinology was thyroid nodules (n=10). Thirteen fine needle aspirations (FNAs) were performed, with follicular tumor (n=6) being the most common finding. The median age of patients at surgery was 15.9 years [interquartile range (IQR): 14.0-16.8]. The most common surgical indications were the presence of a follicular tumor on FNA (n=5) and thyroid nodule size causing symptoms (n=5). There was one case of prophylactic thyroidectomy due to the identification of a multiple endocrine neoplasia type 2A (MEN2A) mutation. The most frequently described histopathology results were follicular adenoma (n=6) and colloid nodular goiter (n=6). Three postoperative complications were observed in three different patients: bilateral lesion of the recurrent laryngeal nerve, cervical hematoma, and transient hypoparathyroidism with hypocalcemia. Conclusion In our study, the most frequent surgical indication was a follicular tumor. A good correlation was found between FNA cytology and final histopathology results, which is in accordance with previous studies. This reinforces the importance of FNA in diagnosis and surgical planning. The rate of complications in our study is comparable to that in larger single-center series in the literature.

Abstract
AIMS Monogenic forms of diabetes that develop with autosomal dominant inheritance are classically aggregated in the Maturity-Onset Diabetes of the Young (MODY) categories. Despite increasing awareness, its true prevalence remains largely underestimated. We describe a Portuguese cohort of individuals with suspected monogenic diabetes who were genetically evaluated for MODY-causing genes. METHODS This single-center retrospective cohort study enrolled patients with positive genetic testing for MODY between 2015 and 2021. Automatic sequencing and, in case of initial negative results, next-generation sequencing were performed. Their clinical and molecular characteristics were described. RESULTS Eighty individuals were included, 55 with likely pathogenic/pathogenic variants in one of the MODY genes and 25 MODY-positive family members, identified by cascade genetic testing. The median age at diabetes diagnosis was 23 years, with a median HbA1c of 6.5%. The most frequently mutated genes were identified in HNF1A (40%), GCK (34%) and HNF4A (13%), followed by PDX1, HNF1B, INS, KCNJ11 and APPL1. Thirty-six unique variants were found (29 missense and 7 frameshift variants), of which ten (28%) were novel. CONCLUSIONS Our data highlights the importance of genetic testing in the diagnosis of MODY and the establishment of its subtypes, leading to more personalized treatment and follow-up strategies.

Abstract
A new avenue has opened up for applications of surface-enhanced Raman spectroscopy (SERS) in the biomedical field, mainly due to the striking advantages offered by SERS tags. SERS tags provide indirect identification of analytes with rich and highly specific spectral fingerprint information, high sensitivity, and outstanding multiplexing potential, making them very useful in in vitro and in vivo assays. The recent and innovative advances in nanomaterial science, novel Raman reporters, and emerging bioconjugation protocols have helped develop ultra-bright SERS tags as powerful tools for multiplex SERS-based detection and diagnosis applications. Nevertheless, to translate SERS platforms to real-world problems, some challenges, especially for clinical applications, must be addressed. This review presents the current understanding of the factors influencing the quality of SERS tags and the strategies commonly employed to improve not only spectral quality but the specificity and reproducibility of the interaction of the analyte with the target ligand. It further explores some of the most common approaches which have emerged for coupling SERS with microfluidic technologies, for biomedical applications. The importance of understanding microfluidic production and characterisation to yield excellent device quality while ensuring high throughput production are emphasised and explored, after which, the challenges and approaches developed to fulfil the potential that SERS-based microfluidics have to offer are described.

Abstract
AIMS To access the impact of increasing use of metformin on cesarean section and large for gestational age rates, when compared to insulin. METHODS A retrospective observational study was developed using data from the Portuguese National Registry, between 2011 and 2019, of 5038 Portuguese women with single pregnancies and gestational diabetes treated with metformin and/or insulin. Three groups were defined according to the therapeutic regimen adopted: g1-insulin in monotherapy (n = 3027[60.1%]); g2-metformin in monotherapy (n = 1366[27.1%]); g3-metformin and insulin (n = 645[12.8%]). Multivariate analysis was adjusted for statistically significant covariates. RESULTS The cesarean section rate in g1 was similar to g2 (g1:36.9% vs. g2:37%, p = 0.982), although g3 was associated with cesarean delivery (g3:43.6% vs. g1:36.9%, p = 0.005; g3:43.6% vs. g1:37.0%, p = 0.002), with no differences reported in the multivariate analysis adjusted for year of delivery and pregestational body mass index. A delivery of a large for gestational age newborn was less frequently observed in g2 than in g1 (g2:4.1% vs. g1:5.4%, p = 0.044) and in g3 (g2:4.1% vs. g3:9.1%, p < 0.001), and in g1, when compared to g3 (g1:5.4% vs. g3:9.1%, p < 0.001). In the multivariate analysis, g2 showed lower odds of delivering a large for gestational age newborn, compared to g1 (β = -0.511, OR = 0.596, CI95% = 0.428-0.832, p < 0.001). CONCLUSIONS The use of metformin was not associated with higher cesarean section rates, compared to insulin. Instead, it was suggested a protective role of metformin on large gestational age rates. The concomitant use of dual therapy suggests more complex pregnancies, requiring closer surveillance that mitigate serious perinatal and obstetrical outcomes.

Abstract
Introduction MODY probability calculator (MPC) represents an easy‐to‐use tool developed by Exeter University to help clinicians prioritize which individuals should be oriented to genetic testing. We aimed to assess the utility of MPC in a Portuguese cohort with early‐onset monogenic diabetes. Methods This single‐centre retrospective study enrolled 132 participants submitted to genetic testing between 2015 and 2020. Automatic sequencing and, in case of initial negative results, generation sequencing were performed. MODY probability was calculated using the probability calculator available online. Positive and negative predictive values (PPV and NPV, respectively), accuracy, sensitivity and specificity of the calculator were determined for this cohort. Results Seventy‐three individuals were included according to inclusion criteria: 20 glucokinase (GCK‐MODY); 16 hepatocyte nuclear factor 1A (HNF1A‐MODY); 2 hepatocyte nuclear factor 4A (HNF4A‐MODY) and 35 DM individuals with no monogenic mutations found. The median probability score of MODY was significantly higher in monogenic diabetes‐positive subgroup (75.5% vs. 24.2%, p < .001). The discriminative accuracy of the calculator, as expressed by area under the curve, was 75% (95% CI: 64%–85%). In our cohort, the best cut‐off value for the MODY calculator was found to be 36%, with a PPV of 74.4%, NPV of 73.5% and corresponding sensitivity and specificity of 76.2% and 71.4%, respectively. Conclusions In a highly pre‐selected group of probands qualified for genetic testing, the Exeter MODY probability calculator provided a useful tool in individuals' selection for genetic testing, with good discrimination ability under an optimal probability cut‐off of 36%. Further geographical and population adjustments are warranted for general use.

Abstract
Introduction In a person with type 1 diabetes, any change concerning daily routine may lead to changes in glycaemic control. This study aimed to evaluate the impact of work and lockdown on glycaemic control in adults with type 1 diabetes. Material and methods A retrospective cohort was stratified into three activity groups (g1-students/telework/laid-off; g2-unemployed/retired; g3-work without lockdown). Continuous and categorical variations (reductions ≥ 0.4%) in glycated haemoglobin were obtained in 2020 (t3:December/2019–March/2020; t4:April/2020–July/2020) and in homologous periods of 2019. Intragroup comparisons between years and intergroups in the same year were made. Regression models were developed to predict the variation of glycated haemoglobin in 2020. Results 241 participants were included, with a significant reduction between t4 and t3 (vs. t2 and t1) in g1 (p < 0.001) and g2 (p = 0.025) and in 2020 in g1 (vs. g2, p < 0.001; vs. g3, p < 0.001). Only g1 presented superiority in the reduction ≥0.4% in glycated haemoglobin in 2020 (vs. 2019, p < 0.001; vs. g2, p < 0.001; vs. g3, p < 0.001). The insulin regimens were comparable and the development of hypoglycaemia was found to be superimposed between t3 and t4, except for g1, which was higher at t3 (p = 0.029). G1 correlated with continuous reductions (vs. g2, p = 0.001; vs. g3, p < 0.001) and ≥0.4% in glycated haemoglobin in 2020 (vs. g2, OR 3.6, p < 0.001; vs. g3, OR 12.7, p < 0.001), regardless of the age and duration of type 1 diabetes. Conclusions A more stable and better glycaemic control was observed in participants who transitioned from face-to-face work to total lockdown.

Abstract
The development of robust and sensitive point-of-care testing platforms is necessary to improve patient care and outcomes. Surface-enhanced Raman scattering (SERS)-based immunosensors are especially suited for this purpose. Here, we present a highly sensitive and selective SERS immunoassay, demonstrating for example the detection of horseradish peroxidase (HRP), in a sandwich format. The strength of our biosensor lies in merging: (i) SERS-immunotags based on gold nanostars, allowing exceptional intense SERS from attached Raman probes, covalent attachment of anti-HRP antibodies by a simple chemical method providing exceptional antigen binding activity; (ii) the ease of preparation of the capture platform from a regenerated cellulose-based hydrogel, a transparent material, ideal for microfluidics applications, with low background fluorescence and Raman signal, particularly suited for preserving high activity of the covalently bound anti-HRP antibodies. The sandwich complexes formed were characterised by atomic force microscopy, and by scanning electron microscopy coupled with electron diffraction spectroscopy; and (iii) the robustness of the simple Classical Least Squares method for SERS data analysis, resulting in superior discrimination of SERS signals from the background and much better data fitting, compared to the commonly used peak integral method. Our SERS immunoassay greatly improves the detection limits of traditional enzyme-linked immunosorbent assay approaches, and its performance is better or comparable to those of existing SERS-based immunosensors. Our approach successfully overcomes the main challenges of application at point-of-care, including increasing reproducibility, sensitivity, and specificity, associated with an environmentally friendly and robust design. Also, the proposed design withstands several cycles of regeneration, a feature absent in paper-SERS immunoassays and this opens the way for sensitive multiplexing applications on a microfluidic platform.

Abstract
Recent focus has been given on the effects of high-intensity infrasound (HII) exposure, and whether it induces changes in pancreatic morphology and glucose metabolism is still unknown. As such, we have studied the impact of HII exposure on glucose tolerance, insulin sensitivity, pancreatic islet morphology, muscle GLUT4 and plasma insulin and corticosterone levels. Normal and glucose intolerant wild-type Wistar rats were randomly divided in two groups: one group not exposed to HII and the other continuously exposed to HII. Animals were sacrificed at three timepoints of exposure (1, 6 or 12 weeks). An intraperitoneal glucose tolerance test was performed, blood samples were collected and the pancreas and the quadriceps femoris muscle were excised. Circulating insulin and corticosterone levels were determined and pancreatic and muscular tissue were routinely processed for histochemistry and immunohistochemistry with an anti-GLUT4 antibody. Animals exposed to HII had higher corticosterone levels than animals not exposed. No differences were found on insulin concerning HII exposure or glucose intolerance. Glucose intolerant animals had pancreatic islet fibrosis and no differences were found in GLUT4 ratio concerning HII exposure. In conclusion, we found that continuous exposure to HII increases stress hormone levels without inducing glucose intolerance in rats.

Abstract
Portugal decriminalized the public and private use, acquisition, and possession of all drugs in 2000; adopting an approach focused on public health rather than public-order priorities. Arguing that the Portuguese Drug Policy Model has not proven influential enough to emancipate drug use from the stigma that associates it either with crime or pathology, this article critically discusses the developments and current challenges the Portuguese drug policy confronts, namely the growing diversity of drug use patterns observed in Portugal as well as in Europe. To this end, international and national legal instruments concerning drugs and official local data were analysed. Despite encouraging results, conclusions indicate that these policies are marked by contradictions and ambiguities that have permeated its history since the very beginning, and modest ambitions, particularly regarding the implementation of harm reduction measures. Moreover, the polemical Supreme Court judgment that reestablished, in 2008, drug use as a crime when the quantities at play exceeded those required for an average individual's use for 10 days, might have impacted the landscape of drug use penalization. The last decade saw an increase of punitiveness targeted at drug users, including criminal sentences of jail terms. We finish with some suggestions that could be employed in the practical application of drug policy.

Abstract
OBJECTIVES Pituitary apoplexy is a rare complication of Cushing's disease (CD), especially in the paediatric age and even more rarely it can occur following anterior pituitary stimulation tests. CASE PRESENTATION We report a case of a 14-year-old girl who was admitted to our Hospital for evaluation of a possible Cushing's syndrome (CS). Her symptoms and initial laboratory tests were suggestive of CD. Magnetic resonance imaging (MRI) revealed a microadenoma of the pituitary gland. As part of her evaluation she was submitted to a corticotropin-releasing hormone (CRH) stimulation test. Two and a half months later the patient was re-evaluated and presented with both clinical improvement of CS, biochemical resolution of hypercortisolism and tumour size reduction in the MRI, also evidencing a haemorrhagic component favouring the diagnosis of pituitary apoplexy after CRH stimulation test. The patient denied any episodes of severe headache, nausea, vomiting or visual changes. CONCLUSIONS To our knowledge, the authors report the first case of a pituitary apoplexy after a CRH stimulation test in the paediatric age.

Abstract
Abstract
Introduction: The high prevalence of vitamin D (vitD) deficiency in the general population is well recognized. Evidence suggests an immunomodulatory role for vitD in pro-inflammatory conditions, but doubt remains on its association with the severity of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) respiratory infection (RI).
Aim: To assess the impact of vitD status on the severity of SARS-CoV-2 RI in adults.
Material and Methods: A cross-sectional study that included adults infected with SARS-CoV-2 until 1/14/2020 was performed. Patients taking calcium, vitD supplementation or antiepileptics, with malabsorptive and/or calcium and phosphate metabolic disorders or stage 4 or 5 chronic kidney disease were excluded. Levels of 25-hydroxyvitamin D (25(OH)D) were obtained at the time of RI diagnosis. The participants were divided into 2 groups, depending on the vitD status (sufficiency and insufficiency [≥20 ng/mL]; deficiency [<20 ng/mL]), and in 3 groups of clinical severity of RI (adapted from the update [14/10/2020] of the standard 004/2020 of the Portuguese Directorate-General for Health): mild/moderate disease (g1); severe disease without bacterial coinfection (g2); severe disease with bacterial coinfection/critical disease (g3). Other factors associated with RI severity were analyzed. A multiple logistic regression model was developed to predict the severity of SARS-CoV-2 RI, considering vitD status as a categorical variable and other variables with statistical significance after univariate analysis.
Results: This study encompassed 71 infected patients with a median age of 68 (p25;p75 = 58;77) years, 40 (56.3%) of which were women. 32 (45.1%) patients integrated g1, 14 (19.7%) g2 and 25 (35.2%) g3. 39 (54.9%) presented vitD deficiency and 32 (45.1%) vitD sufficiency or insufficiency. In the univariate analysis, vitD deficiency, age (>60 years old), male gender, Arterial Hypertension, Diabetes Mellitus, use of angiotensin-II receptor antagonist and reduced levels of ionized serum calcium correlated with the severity of RI. In the multivariate regression model that included these variables, vitD deficiency remained independently correlated with critical/severe disease with bacterial coinfection (g3 vs. g1: OR=9.7; CI95%=[1.7; 56.4]; p=0.011; g3 vs. g2: OR=6.3; CI95%=[1.1–37.0]; p=0.044), with a tendency, albeit not statistically significant, for severe RI without bacterial coinfection (g2 vs g1: OR=1.6; CI95%=[0.3; 7.4]; p=0.581).
Conclusions: An independent association of vitD deficiency with the severity of SARS-CoV-2 RI was found, supporting the anti-inflammatory effects of vitD. It is essential to identify and treat its deficiency in patients prone to adverse outcomes of SARS-CoV-2 RI.

Abstract
Simple Summary Thyroid cancer incidence is increasing, with overdiagnosis being the major driver of the thyroid cancer “epidemic”. Papillary thyroid carcinoma, usually with excellent prognosis, sometimes has an aggressive metastatic pattern. This heterogeneity in progression makes it difficult to tailor treatment strategies for an individual patient. We aimed to identify clinicopathological factors associated with papillary thyroid carcinoma recurrence, persistence, and specific mortality. Our study supports that both pre-surgical factors, such as male gender, presence of psammoma bodies, gross extra-thyroidal extension, and lateral compartment lymph node metastases, as well as lymph vessel invasion, venous invasion, presence of necrosis, and incomplete surgical resection, should be taken into consideration regarding treatment and follow-up of PTC patients. The same is true when analysis is restricted to stage I patients. The importance of this report is to emphasize clinical and imaging pre-surgical thyroid cancer patients’ evaluation for an appropriate surgical treatment and patient prognosis. Abstract Papillary thyroid cancer (PTC) has an indolent nature and usually excellent prognosis. Some PTC clinicopathological features may contribute to the development of aggressive metastatic disease. In this work, we want to evaluate PTC clinicopathological features that are presurgical prognostic predictors of patients’ outcomes and find which indicators are more adequate for tailoring surgical procedures and follow-up. We studied a series of 241 PTC patients submitted to surgery. All patients’ files and histological tumor samples were reviewed. The 8th edition AJCC/UICC (American Joint Committee on Cancer/Union for International Cancer) Controlstaging system and the 2015 American Thyroid Association risk stratification system were used. Total thyroidectomy was performed in 228 patients, lymphadenectomy in 28 patients. Gross extrathyroidal extension (ETE) was present in 10 patients and 31 tumor resection margins were incomplete. Cervical lymph node metastases (LNMs) were present in 34 patients and distant metastases at diagnosis in four patients. In multivariate analysis, male gender (OR = 15.4, p = 0.015), venous invasion (OR = 16.7, p = 0.022), and lateral compartment LNM (OR = 26.7, p = 0.004) were predictors of mortality; psammoma bodies (PBs) (OR = 4.5, p = 0.008), lymph vessel invasion (OR = 6.9, p < 0.001), and gross ETE (OR = 16.1, p = 0.001) were predictors of structural disease status; male gender (OR = 2.9, p = 0.011), lymph vessel invasion (OR = 2.8, p = 0.006), and incomplete resection margins (OR = 4.6, p < 0.001) were predictors of recurrent/persistent disease. Our study supports that the factors helping to tailor patient’s surgery are male gender, presence of PBs, gross ETE, and lateral compartment LNM. Together with pathological factors, lymph vessel invasion, venous invasion, necrosis, and incomplete surgical resection, should be taken into consideration regarding treatment and follow-up of patients.

Abstract
BACKGROUND To determine if periodontal risk assessment (PRA), the number of missing teeth, diabetes mellitus (DM), perceived stress and interproximal cleaning are associated with oral health-related quality of life (OHRQoL), using Andersen's behavioral modelling (ABM). MATERIAL AND METHODS Data derived from 472 adults derived from a representative population of the Study of Periodontal Health in Almada-Seixal (SoPHiAS) was used. Socioeconomic status, perceived stress scale (PSS-10), oral health behaviors and oral health impact profile (OHIP-14) were collected through questionnaire. Periodontal conditions were assessed with a full-mouth periodontal examination. PRA was computed through behavioral and clinical information. Variables were grouped into Predisposing Factors, Enabling, Need, Oral Health Behaviors and Perceived Health Outcome latent variables. Confirmatory factor analysis, structural ABM and model fitness were conducted. RESULTS ABM applied to OHIP-14 showed acceptable model fit (χ2 = 2.75, CFI = 0.92, TLI = 0.90, RMSEA = 0.05, CI 90% [0.04-0.07]). The average of OHRQoL was 9.5 ± 11.3. Patient with periodontitis and with a high number of missing teeth experienced worse OHRQoL. Uncontrolled DM participants had more periodontal treatment necessity and poorer OHRQoL. Characteristic like aging and lower levels of education were directly associated with better OHRQoL, but in indirect path the OHRQoL was diminishes. Good oral hygiene and preventative measures were associated to lower periodontal treatment necessity. Lower periodontal treatment necessity was associated to higher OHRQoL. Age, tooth loss and interproximal cleaning were the most associated items to Predisposing, Need and Oral Health Behaviors, respectively. CONCLUSION ABM confirmed age, number of missing teeth, DM, interproximal cleaning and perceived stress as associated factors for OHRQoL. Uncontrolled DM was associated to higher Need and poorer OHRQoL. Good oral hygiene habits promote a healthy periodontium and, consequently, increases OHRQoL.

Abstract
Previous experimental studies show that exposure to noise with high and audible frequencies causes multiple metabolic alterations, such as increased liver glycogen and triglycerides. However, the effect of exposure to sound with lower frequencies, such as high-intensity infrasound (frequency <20 Hz and sound pressure level >90 dB), on the liver lipid content is still unclear. As such, we aimed to study the effect of exposure to high-intensity infrasound of both normal and glucose intolerant rats on the liver lipid content. For this study, 79 wild-type male Wistar rats were randomly divided into two groups: G1, no treatment, and G2, induced glucose intolerance. Each of these two groups was randomly divided in two subgroups: s (animals kept in silence) and i (animals continuously exposed to high-intensity infrasound noise). At three noise-exposure time-points (1, 6 and 12 weeks) the rats were sacrificed, the liver was excised and hepatic lipids extracted. Data analysis was performed using a two-way ANOVA (p = 0.05). No significant effects due to interactions between the several factors exist on the liver lipid content (p=0.077). Moreover, no significant effects due to infrasound exposure (p=0.407) or glucose tolerance status (p=0.938) were observed. Our study shows that continuous exposure to high-intensity infrasound has no influence on the lipid content of the liver of both normal and glucose intolerant animals. This finding reinforces the need for further experimental studies on the physiological effects of infrasound due to its possible hazardous effects on human health.

Abstract
BACKGROUND To investigate if self-perceived xerostomia and stress are significant variables on the Oral-Health Related Quality of Life (OHRQoL) of elderly patients, considering the periodontal status, oral hygiene habits and sociodemographic characteristics simultaneously. METHODS The study cohort included 592 participants (320 females/272 Males), aged 65 years or older, representing the elder inhabitants of the Study of Periodontal Health in Almada-Seixal (SoPHiAS). Patients answered a socio-demographic and oral hygiene habits questionnaire. The Oral Health Impact Profile-14 (OHIP-14), Summated Xerostomia Inventory-5 (SXI-5) and Perceived Stress Scale-10 (PSS-10) were used. Full-mouth circumferential periodontal inspection was carried out. Multivariable regression analyses were used considering the level of periodontitis, clinical characteristics, the number of teeth, SXI, PSS-10, age, gender and oral hygiene habits. RESULTS Self-perceived xerostomia and stress showed a positive significant correlation with OHRQoL and each of its domains. Multiple linear regression analysis demonstrated the significant impact of SXI-5 (B = 1.20, p < 0.001) and PSS-10 (B = 0.35, p < 0.001) on the OHRQoL. SXI-5 (Odds Ratio (OR) = 1.28, p < 0.001) and PSS-10 (OR = 1.03, p = 0.022) were associated with a more frequently affected OHRQoL. The number of missing teeth, being male, mean probing depth and mean clinical attachment loss were also significant towards a frequently affected OHRQoL. Conversely, age was negatively associated with a lower OHRQoL. CONCLUSION Self-perceived xerostomia and stress are significant variables towards OHRQoL in elderly patients. Future studies should consider these self-perceived xerostomia and stress when investigating the impact of periodontitis and missing teeth on quality of life of older adults.

Abstract
Background
Noise is an important environmental risk factor. Industrial environments are rich in high-intensity infrasound (hi-IFS), which we have found to induce myocardial and coronary perivascular fibrosis in rats. Recently, a significant association between noise exposure and the incidence of atrial fibrillation (AF) was found in large cohort studies but the pathophysiology is unclear. Atrial fibrosis remains the cornerstone of atrial pathology in AF. Purpose: We hypothesized that rats exposed to hi-IFS develop atrial remodeling involving fibrosis and connexin 43, which we sought to evaluate. Material and Methods: Seventy-two Wistar rats, half exposed to hi-IFS (120dB, <20Hz) during a maximum period of 12 weeks and half age-matched controls, were studied. Atrial fibrosis was analyzed by Chromotrope-aniline blue staining. The immunohistochemical evaluation of Cx43 was performed using the polyclonal antibody connexin-43m diluted 1:1000 at 4ºC overnight. Digitized images were obtained with an optical microscope using 400× magnifications. The measurements were performed using image J software. A two-way ANOVA model was used to compare the groups. Results: The mean values of the ratio "atrial fibrosis / cardiomyocytes" increased to a maximum of 0,1095 ± 0,04 and 0,5408 ± 0,01, and of the ratio "CX43 / cardiomyocytes" decreased to 0,0834 ± 0,03 and 0,0966 ± 0,03, respectively in IFS-exposed rats and controls. IFS-exposed rats exhibited a significantly higher ratio of fibrosis (p < 0,001) and lower ratio of Cx43 (p = 0,009). Conclusion: High-intensity infrasound exposure triggers atrial remodeling in rat hearts. Whether this finding correlates to arrhythmogenic substrate in noise induced-AF is not known and reinforces the need for further experimental studies.

Abstract
Co-occurrence of hyperinsulinaemic hypoglycaemia and polycystic kidney disease (HIPKD) has been recently described. It is caused by a non-coding variant in the promoter region for phosphomannomutase 2 (PMM2), c.-167G>T, both in homozygous or compound heterozygous variants with deleterious coding. Although PMM2 has been associated with congenital disorder of glycosylation, patients do not present with this phenotype and have normal carbohydrate-deficient transferring testing. The authors present a rare case where specific PMM2 study was performed as a result of clinical suspicions. The patient was a 6-year-old female followed at our clinic due to congenital hyperinsulinism since she was 1 month old. She also presented with bilateral polycystic kidneys, detected in prenatal set, and simple hepatic cysts, for which she was treated with diazoxide and captopril. Initial metabolic and genetic studies were normal. PMM2 gene sequence study revealed the promotor variant c.-167G>T in compound heterozygosity with the previously described pathogenic variant c.422G>A (p.Arg141His), confirming the diagnosis of HIPKD. This is a notable case as it highlights the importance of keeping this diagnostic hypothesis in mind and serves as a reminder to perform proper clinical and genetic investigation. A correct, and early, diagnosis will avoid unnecessary additional investigations and will allow appropriate genetic counselling for this autosomal recessive disorder.

Abstract
Objective The aim of this study was to evaluate the impact of pre-pregnancy body mass index (BMI) on pregnancy outcomes in women with gestational diabetes (GD). Subjects and methods Retrospective multicenter study using data from the Portuguese National Register. We included women with GD with a singleton pregnancy. GD diagnosis was according to the International Association of the Diabetes and Pregnancy Study Group criteria. Women were divided into groups according to their pre-pregnancy BMI: < 18.5 kg/m2 (underweight), ≥ 18.5 and < 25.0 kg/m2 (normal weight), ≥ 25 and < 30 kg/m2 (overweight) and ≥ 30 kg/m2 (obese). Results We included 3,103 pregnant women with GD, 29.6% (n = 918) were overweight and 27.3% (n = 846) were obese. Compared to normal weight, the overweight and obese groups had a higher percentage of gestational hypertension (4.0% and 8.5% vs. 2.1%), cesarean delivery (32.8% and 41.3% vs. 27.9%), macrosomia (3.9% and 6.7% vs. 2.4%), and large for gestational age (LGA) newborns (8.3% and 13.5% vs. 6.0%). Obesity increased the risk of gestational hypertension (OR 4.5, p < 0.001), preeclampsia (OR 1.9, p = 0.034), cesarean delivery (OR 2.0, p < 0.001), macrosomia (OR 3.1, p < 0.001) and LGA (OR 2.3, p < 0.001). Conclusion In pregnant women with GD, pregnancy complications increase with pre-pregnancy BMI. In obese women, appropriate diet and counseling prior to gestation and more aggressive medical intervention during pregnancy are needed in order to prevent macrosomic and LGA newborns and to reduce maternal complications.

Abstract
INTRODUCTION
An 83-year-old woman with a past medical history of hypertension, dyslipidaemia and recent diagnosis of disseminated breast cancer was admitted at Emergency department for acute heart failure. She complained about short chest pain episodes on previous days, the ECG showed new T negative waves on precordial leads and high sensitive troponin serum levels were modestly increased (TropT 1200ng/l). Echocardiographic assessment documented moderate left ventricular dysfunction (LVEF 40%) with apical and midventricular dyskinesia associated with hypercontractility off basal segments.
The following day the patient underwent a coronary angiography that showed an occlusion in the distal segment of a large obtuse marginal branch (Panel A) with no other significant stenosis in the remaining vessels. Ventriculography showed a typical apical ballooning pattern (Panel B). Despite the occluded coronary artery was reaching the apex, the myocardial wall motion abnormalities extended beyond the ischemic territory. Therefore, a cardiac magnetic resonance (CMR) was performed a few days later in order to clarify the diagnosis.
CMR confirmed the mid LVEF dysfunction with apical dyskinesia and the T2 weighted spin echo images showed myocardial oedema in all the apical segments (Panel C). Remarkably, a subedocardial late gadolinium enhancement (LGE) restricted to the apical segment of the inferolateral wall was detected, being consistent with the ischaemic territory of the occluded obtuse marginal branch (Panel D). These findings supported the concomitant diagnosis of an apical stress cardiomyopathy and an acute inferolateral myocardial infarction. The patient was successfully discharged one week later with a normal LVEF and no signs of congestion.
DISCUSSION
Apical ballooning in the scenario of an acute coronary syndrome may be secondary to both an acute coronary artery occlusion or to stress cardiomyopathy. Cardiac MR has a key role to resolve the differential diagnosis of these two aetiologies, since ischemia typically produces a subendocardial late gadolinium enhancement pattern and stress cardiomyopathy shows an apical oedema without coronary stenosis or extending beyond a localized ischemic territory. Our case is astonishing because in the clinical practice these two diagnoses frequently excludes each other, but as demonstrated in our case, the differential diagnosis between myocardial infarction and stress cardiomyopathy is not a proper dichotomy.

Abstract
BACKGROUND Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder characterized by 3 overlapping phenotypes: salt-wasting (SW), simple virilizing (SV), and non-classic (NC). We aimed at conducting a nationwide genotype description of the CAH pediatric patients and to establish their genotype-phenotype correlation. METHODS CAH patients were recruited from Portuguese pediatric endocrinology centers and classified as SW, SV, or NC. Genetic analysis was performed by polymerase chain reaction (sequence specific primer, restriction fragment length polymorphism) or direct Sanger sequencing. Genotypes were categorized into 4 groups (0, A, B, and C), according to their predicted enzymatic activity. In each group, the expected phenotype was compared to the observed phenotype to assess the genotype-phenotype correlation. RESULTS Our cohort comprises 212 unrelated pediatric CAH patients (29% SW, 11% SV, 60% NC). The most common pathogenic variant was p.(Val282Leu; 41.3% of the 424 alleles analyzed). The p.(Val282Leu) variant, together with c.293-13A/C>G, p.(Ile173Asn), p.(Leu308Thr), p.(Gln319*), and large deletions/conversions were responsible for 86.4% of the mutated alleles. Patients' stratification by disease subtype revealed that the most frequent pathogenic variants were c.293-13A/C>G in SW (31.1%), p.(Ile173Asn) in SV (46.9%), and p.(Val282Leu) in NC (69.5%). The most common genotype was homozygosity for p.(Val282Leu; 33.0%). Moreover, we found 2 novel variants: p.(Ile161Thr) and p.(Trp202Arg), in exons 4 and 5, respectively. The global genotype-phenotype correlation was 92.4%. Group B (associated with the SV form) showed the lowest genotype-phenotype correlation (80%). CONCLUSION Our cohort has one of the largest NC CAH pediatric populations described. We emphasize the high frequency of the p.(Val282Leu) variant and the very high genotype-phenotype correlation observed.

Abstract
Immunoassays using Surface-Enhanced Raman Spectroscopy are especially interesting on account not only of their increased sensitivity, but also due to its easy translation to point-of-care formats. The bases for these assays are bioconjugates of polyclonal antibodies and anisotropic gold nanoparticles functionalized with a Raman reporter. These bioconjugates, once loaded with the antigen analyte, can react on a sandwich format with the same antibodies immobilized on a surface. This surface can then be used for detection, on a microfluidics or immunochromatographic platform. Here, we have assembled bioconjugates of gold nanostars functionalized with 4-mercaptobenzoic acid, and anti-horseradish peroxidase antibodies. The assembly was by simple incubation, and agarose gel electrophoresis determined a high gold nanostar to antibody binding constant. The functionality of the bioconjugates is easy to determine since the respective antigen presents peroxidase enzymatic activity. Furthermore, the chosen antibody is a generic immunoglobulin G (IgG) antibody, opening the application of these principles to other antibody-antigen systems. Surface-Enhanced Raman Spectroscopy analysis of these bioconjugates indicated antigen detection down to 50 µU of peroxidase activity. All steps of conjugation were fully characterized by ultraviolet-visible spectroscopy, dynamic light scattering, ζ -Potential, scanning electron microscopy, and agarose gel electrophoresis. Based on the latter technique, a proof-of-concept was established for the proposed immunoassay.

Abstract
Cancer immunotherapy has been used in several malignancies with clinical benefit. Despite the clinical success, immune-related adverse events are frequent and endocrinopathies can be particularly severe. We report a 55-year-old male patient with stage IV pulmonary carcinoma treated with nivolumab who presented with thyroid dysfunction after the sixth administration of the drug. One year after thyroid dysfunction, the patient complained of severe fatigue, asthenia and weight loss. Laboratory testing showed low morning cortisol with undetected adrenocorticotropic hormone; other pituitary hormones were normal and MRI showed homogeneous enhancement of the pituitary gland and no space-occupying lesions. The diagnosis of nivolumab-induced hypophysitis was made and replacement treatment with hydrocortisone was started with clinical improvement. This case demonstrates that patients under immunotherapy are at risk for a large spectrum of endocrine dysfunctions that may worsen their prognosis. Close monitoring of these patients is warranted.

Abstract
Fetal goitrous hypothyroidism is a rare entity and is caused mainly by maternal treatment of Graves' disease (GD). We report a case of a 22-year-old woman referred at 12 weeks of gestation due to hyperthyroidism subsequent to recently diagnosed GD. She started treatment with propylthiouracil and, at 21 weeks of gestation, fetal goitre was detected. A cordocentesis confirmed the diagnosis of fetal goitrous hypothyroidism, and intra-amniotic administration of levothyroxine (LT4) was performed and repeated through the pregnancy due to maintenance of fetal goitre. The pregnancy proceeded without further complications and a healthy female infant was born at 37 weeks of gestation, with visible goitre and thyroid function within the normal range at birth. Although there is no consensus on the optimal dose, the number of injections and the interval between them, intra-amniotic LT4 administration is recommended once fetal goitrous hypothyroidism is suspected, in order to prevent long-term complications of fetal hypothyroidism.

Abstract
Alpha-1-antitrypsin deficiency (AATD) is a genetic autosomal codominant disorder caused by mutations in SERPINA1 gene. It is one of the most prevalent genetic disorders, although it remains underdiagnosed. Whereas at international level there are several areas of consensus on this disorder, in Portugal, inter-hospital heterogeneity in clinical practice and resources available have been adding difficulties in reaching a diagnosis and in making therapeutic decisions in this group of patients. This raised a need to draft a document expressing a national consensus for AATD. To this end, a group of experts in this field was created within the Portuguese Pulmonology Society - Study group on AATD, in order to elaborate the current manuscript. The authors reviewed the existing literature and provide here general guidance and extensive recommendations for the diagnosis and management of AATD that can be adopted by Portuguese clinicians from different areas of Medicine. This article is part of a supplement entitled "Portuguese consensus document for the management of alpha-1-antitrypsin deficiency" which is sponsored by Sociedade Portuguesa de Pneumologia.

Abstract
Introduction: Thyroid hormones have an important role in the regulation of lipid metabolism. Higher levels of TSH could be associated with impaired lipid profile and cardiovascular disease, even with normal levels of free thyroxine (FT4). The aim of this study was to investigate the association between TSH levels and lipid profile in patients with primary hypothyroidism. Materials and methods: Retrospective evaluation of patients with primary hypothyroidism treated with levothyroxine (LT4), with normal levels of FT4. Patients with known dyslipidemia were excluded. Thyroid function, total cholesterol (TC), triglycerides (Tg), HDL-cholesterol (HDL) and LDL-cholesterol (LDL) were studied. Patients were divided according to their TSH levels: <2.5 uUI/mL (group 1), 2.5 ≤TSH< 5.0 uUI/mL (group 2) and ≥5.0 uUI/mL (group 3). IBM SPSS Statistics® software was used for statistical analysis; p level <0.05 was considered statistically significant. Results: We included 126 patients, 88.1% female, with mean age 46.1±14.1 years. The majority had auto-immune hypothyroidism (n=65, 51.6%) followed by post-surgical hypothyroidism (n=43, 34.1%). Mean TC levels were 180.7±35.2mg/dL, LDL levels 105.3±26.6mg/dL and Tg levels 100.1±47.9mg/dL. For higher TSH values, there was an increase in mean TC levels (group 1: 168.9mg/dL, group 2: 187.4mg/dL, group 3: 198.4mg/dL, p<0.001), mean LDL levels (group 1: 98.5mg/dL, group 2: 117.9mg/dL, group 3: 119.8mg/dL, p=0.003) and mean Tg levels (group 1: 86.1mg/dL, group 2: 104.5mg/dL, group 3: 119.9mg/dL, p=0.002). Between patients in group 1 and 3 there was a significant difference in serum TC, LDL and Tg levels (p<0.001, p=0.001 and p=0.001, respectively). Patients with hypothyroidism following thyroidectomy for malignant disease had significantly lower median TSH values compared to other types of hypothyroidism (1.1uUI/mL vs 3.0uUI/mL, p=0.003) and had lower mean TC values (174.2mg/dL vs 181.7mg/dL, p>0.05) and lower mean LDL levels (96.3mg/dL vs 106.7mg/dL, p>0.05). TSH values positively correlated with higher TC levels (r=0.319, p<0.001), LDL levels (r=0.267, p=0.003) and Tg levels (r=0.264, p=0.003). Conclusions: Serum lipid levels were higher among patients with higher TSH values, especially in those with TSH ≥5.0 uUI/mL, suggesting that subclinical hypothyroidism may be associated with mild dyslipidemia. Even though there is insufficient evidence to recommend treatment with LT4 to achieve low-normal TSH values in order to accomplish better lipid control, it may be beneficial in high risk patients. It would be interesting to evaluate lipid profile following an increase in LT4 dose, in order to better understand the effect of levothyroxine in these patients.

Abstract
Critically ill patients are at risk of developing stress ulcers in the upper
digestive tract. Agents that suppress gastric acid are commonly prescribed to
reduce the incidence of clinically important stress ulcer-related
gastrointestinal bleeding. However, the indiscriminate use of stress ulcer
prophylaxis in all patients admitted to the intensive care unit is not warranted
and can have potential adverse clinical effects and cost implications. The
present guidelines from the Sociedade Portuguesa de Cuidados
Intensivos summarizes the current evidence and gives six clinical
statements and an algorithm aiming to provide a standardized prescribing policy
for the use of stress ulcer prophylaxis in the intensive care unit.

Abstract
Semiconductor nanowires are mostly processed by complex, expensive, and high temperature methods. In this work, with the intent of developing zinc tin oxide nanowires (ZTO NWs) by low-cost and low-complexity processes, we show a detailed study on the influence of chemical parameters in the hydrothermal synthesis of ZTO nanostructures at temperatures of only 200 °C. Two different zinc precursors, the ratio between zinc and tin precursors, and the concentration of the surfactant agent and of the mineralizer were studied. The type and the crystallinity of the nanostructures were found to be highly dependent on the used precursors and on the concentration of each reagent. Conditions for obtaining different ZTO nanostructures were achieved, namely, Zn2SnO4 nanoparticles and ZnSnO3 nanowires with length ∼600 nm, with the latter being reported for the first time ever by hydrothermal methods without the use of seed layers. Optical and electrical properties were analyzed, obtaining band gaps of 3.60 and 3.46 eV for ZnSnO3 and Zn2SnO4, respectively, and a resistivity of 1.42 kΩ·cm for single ZnSnO3 nanowires, measured using nanomanipulators after localized deposition of Pt electrodes by e-beam assisted gas decomposition. The low-temperature hydrothermal methods explored here proved to be a low-cost, reproducible, and highly flexible route to obtain multicomponent oxide nanostructures, particularly ZTO NWs. The diversity of the synthesized ZTO structures has potential application in next-generation nanoscale devices such as field effect nanotransistors, nanogenerators, resistive switching memories, gas sensors, and photocatalysis.

Abstract
INTRODUCTION Six-minute walk test (6MWT) is used for evaluating functional exercise capacity. To the best of our knowledge, there are no reference equations to predict six-minute walk distance (6MWD) for the Portuguese population. The aims of the present study were to measure anthropometric data and 6MWD in a sample of healthy Portuguese population, to establish reference equations to predict 6MWD and to compare our equations with those obtained by previously published studies. METHODS We conducted an observational prospective study. We consecutively recruited 158 healthy 18-70 years old subjects from Porto district, who performed two 6MWTs using a standardized protocol. The best 6MWD was used for further analysis. RESULTS The mean 6MWD was 627.8m (SD=73.3m). The variables that were significantly associated with the 6MWD were age, sex, BMI and ΔHR (Heart Rateat the end of the test-HRat rest). We found three explanatory models for 6MWD, the best with an explanatory power of 38%: 6MWD=721.7-1.6×Age-4.0×BMI+0.9×ΔHR+58.4×Sex. We verified that 6MWD decreased 1.6m per year of age, and 4.0m per unit of BMI and increased 0.892m per beat per minute. Moreover, on average, males walk 58.4m more than females (p<0.001). Applying equations from other studies to our population resulted in an overestimation or underestimation of the 6MWD. CONCLUSION The present study was the first to describe the 6MWD in healthy Portuguese people aged 18-70 years old and to propose predictive equations. These can contribute to improving the evaluation of Caucasian Mediterranean patients with diseases that affect their functional capacity.

Abstract
INTRODUCTION Asthma and obesity have a considerable impact on public health and their prevalence is increasing. Obesity is a known risk factor for asthma and can make it more difficult to control. Omalizumab is recommended in patients with severe allergic persistent asthma. The aim of this study was to assess the impact of omalizumab treatment in obese asthmatic patients with poorly controlled severe persistent asthma. METHODOLOGY A non-interventional, prospective study was conducted, in an outpatient asthma clinic. All patients with severe asthma who started treatment with omalizumab were included and followed over 12 months. The study population was divided into two groups (obese and non-obese) for statistical analysis (descriptive and comparative analysis). RESULTS Thirty-two patients (19 obese) were followed. After 12 months of omalizumab treatment, there was a statistically significant improvement in body mass index, number of exacerbations in the previous year, rescue medication, disease control and lung function, in the whole population. At the end of the study obese patients had a significantly better lung function (FEV1) than non-obese. DISCUSSION As described in the literature, there was a significant reduction in the number of exacerbations in the previous year, rescue medication and better disease control, in the whole population. In relation to lung function, about which published data are inconsistent, treatment with omalizumab significantly improved it in obese patients. CONCLUSION Our study showed that omalizumab significantly improved asthma control, reduced rescue medication and asthma exacerbations in all the population; and for the first time showed that obese patients achieved significantly improved lung function.

Abstract
BACKGROUND Although the incidence rates of non-tuberculous mycobacteria (NTM) have been increasing in many countries, the basic epidemiology of NTM remains to be fully understood. OBJECTIVE To assess the incidence, clinical relevance and geographical distribution of NTM disease in Portugal and to identify demographic and clinical characteristics associated with Mycobacterium avium complex (MAC) disease. METHODS Information stored in an electronic database of all NTM cases reported over an 11-year period was retrospectively reviewed. Significant demographic and clinical characteristics of MAC disease (vs. having any other NTM disease) were determined using multiple logistic regression models. RESULTS We identified 632 patients, mostly male, native Portuguese, with pulmonary disease, predominantly from Lisbon and Porto. The annual incidence of NTM disease was 0.54 per 100 000 population. The annual number of NTM cases increased throughout the study period. MAC was most frequently isolated. MAC disease was positively (and significantly) associated with being female, age >45 years and human immunodeficiency virus infection. CONCLUSIONS The increasing incidence of NTM over the study period emphasises the importance of NTM as a public health issue. This study provides important information for health care professionals and a basis for further study of NTM in Portugal.

Abstract
INTRODUCTION Graves' disease (GD) is an autoimmune thyroid disease, common in adults but rare in children. The best therapeutic approach remains controversial. OBJECTIVES To ascertain the current treatment of pediatric GD in Portugal and to assess the clinical and biochemical factors that determine definitive/long-term remission after treatment with antithyroid drugs (ATDs). PATIENTS AND METHODS A retrospective analysis of data about pediatric GD treatment collected from a nationwide survey conducted by the Portuguese Society of Pediatric Endocrinology and Diabetology from May to August 2013. Population was categorized based on sex, age, use of ATDs, dosage, treatment duration, adverse reactions, thyrotropin receptor-stimulating antibody (TRAB) titer, remission and remission/relapse rates, and definitive treatment, and divided into group A (with ongoing treatment) and group B (with treatment stopped). Group B was subdivided into 'Remission', 'Remission+relapse' and 'No remission' subgroups based on the course of disease. The same parameters were compared between both groups. RESULTS Survey response rate was 77%; 152 subjects, 116 female, mean age at diagnosis 11.23±3.46 years. They all started treatment with ATDs, 70.4% with thiamazole, with a mean treatment duration of 32.38±28.29 months, and 5.9% had adverse effects. Remission rate was 32.6%. Lower age at diagnosis correlated with higher remission rates. Treatment duration was longer when propylthiouracil was used. Initial TRAB titer was significantly higher in the 'No remission' group. Surgery and radioiodine were used as second-line treatments. CONCLUSION Our study results were similar to those reported in the literature. Age and TRAB titer were identified as potential clinical and laboratory determinants of remission. Based on risk/benefit analysis, it was concluded that treatment should be individualized based on age, accessibility to treatments, and physician's experience.

Abstract
INTRODUCTION Erectile dysfunction (ED) is the inability to achieve or maintain an erection for satisfactory sexual activity. Recent studies have shown an association between ED and chronic obstructive pulmonary disease (COPD). However, this issue is often ignored. We aimed to evaluate the ED prevalence in COPD patients and its risk factors and to study the impact of dyspnea in sexual activity. METHODS Cross-sectional study that included sexually active male patients with COPD. The International Index of Erectile Function (IIEF-5) questionnaire evaluated ED and the Respiratory Experiences with Sexuality Profile (RESP) was used to evaluate the impact of dyspnea on sexual activity. Risk factors for mild-moderate or moderate ED were determined using logistic regression. RESULTS 84 patients were consecutively assessed for eligibility, 67 were included (median age: 65 years, 13% never-smokers). Twenty two percent had COPD 2011-GOLD A; 22% GOLD B, 14% GOLD C and 42% GOLD D. Fifty-eight patients (87%) had some degree of ED: 26 (45%) mild, 20 (34%) mild-moderate and 12 (21%) moderate ED. ED occurred in all GOLD stages of COPD, mainly in GOLD B and D stages. Higher CAT score was independently associated to mild-moderate/moderate ED. Most patients (85%) reported dyspnea during their sexual activity but 72% had never talked about it with their physician. CONCLUSIONS ED is highly prevalent among COPD patients and it is more severe in patients with higher CAT scores. Dyspnea affects their sexual activity but this is not a topic often discussed between patients and doctors, something which needs to be improved.

Abstract
INTRODUCTION Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular/metabolic complications. Some analytical parameters (homocysteine, glycemic and lipidic profiles) are recognized markers of these consequences. Limited data is available on the association of these markers and OSAS's severity/response to positive airway pressure therapy (PAP). MATERIAL AND METHODS In this prospective study we analyzed polysomnographic and analytical data of male patients admitted to sleep laboratory. The aim was to evaluate metabolic/cardiovascular markers in snorers and OSAS patients, to relate with sleep parameters and PAP response. One-hundred and three patients were included, and 73 (71%) were OSAS patients. OSAS patients were similar to snorers except for higher body mass index (BMI) and dyslipidemia. Severe OSAS patients showed higher glycemia, HbA1c, insulin, and insulin resistance, and lower HDL cholesterol in comparison to mild-moderate (p<0.05, p<0.05, p<0.001, p<0.001, p<0.05, respectively). Glycemic profile and triglycerides were slightly correlated with OSAS severity. 46 OSAS patients were submitted to 6 months of PAP, with a statistical decrease in mean values of homocysteine, glycemia, total and LDL cholesterol (p<0.05, p<0.05, p<0.05, respectively), and in glycemia and LDL cholesterol in severe group only (p<0.05, p<0.05, respectively). RESULTS This study demonstrated an association between glucose metabolism parameters and triglycerides with OSAS severity underlying the complexity of the process leading to cardiovascular/metabolic complications in this disorder. Moreover, homocysteine, glycemic and lipidic profiles changed significantly after 6 months of PAP therapy in OSAS, supporting its cardiovascular and metabolic protective effect. CONCLUSION Our study has reinforced the importance of analytical cardiovascular/metabolic evaluation as complementary tool of diagnosis/treatment response in OSAS.

Abstract
In the field of veterinary anatomy, most of the specimens used in practical sessions are perfused with fixatives. Thus, they can be used for a longer time, reducing the number of animals for educational purposes. Formalin is the most commonly used fixative, consisting of a 37% formaldehyde solution. However, formaldehyde is a powerful irritant of the eyes and airways and is considered carcinogenic, causing nasopharyngeal cancer in exposed workers and professionals. In the present study, we explored an alternative method to avoid the use of formaldehyde in specimens used for gross anatomy practical sessions. We propose an inexpensive, non-toxic fixative that is available worldwide, such as sea salt. This method consists of a continuous perfusion of saturated salt solution for a period of 6-8 h, enabling drainage of the solution to avoid a weight increase of the specimen, and allowing salt to be retained in the tissue. The method is based on recirculation of the saturated salt solution instead of maceration. Perfused specimens retained their natural consistency and joint mobility, with no blood, resembling a piece of meat from the slaughterhouse. They could be used immediately without a maceration period, or stored in the fridge until use and then kept in a bath of saturated salt solution for future conservation. In the case of the former, no refrigeration was needed. The specimens did not have an irritating or offensive smell, and could be used for long sessions (several hours per day) and stored for long periods. However, the blood vessels used for perfusion determine the results: a less invasive approach (through common carotid arteries) gave good preservation of the musculoskeletal system, whereas more invasive access to cannulate the abdominal aorta and vena cava caudalis was required to achieve better preservation of the viscera. In conclusion, we propose that perfusion followed by immersion in a saturated salt solution is a good alternative method for the preservation of specimens used in the practical teaching of gross veterinary anatomy. It is a very simple and inexpensive technique, and is much healthier for users than traditional formalin. Moreover, specimens can be preserved for prolonged periods, and maintain a similar appearance and consistency to fresh material.

Abstract
AIMS To prospectively validate the existing classifications to stratify subjects with diabetes mellitus (DM) by their risk of diabetic foot ulcer (DFU), in high and low risk settings. METHODS A prospective multicentre cohort study was conducted, including 446 subjects with DM without active DFU followed in the hospital or primary care setting. Demographic, clinical characterization variables, and those included in the classifications were collected at baseline. Subjects were followed for 1year, until DFU or death. RESULTS In our sample, with a mean age of 65years, 52% were male; 32 developed a DFU, 7 required an amputation and 18 died. Differences were found between participants' characteristics and classifications' accuracy according to the setting. The great majority of the variables were associated with higher DFU risk. Globally, classifications were highly and equally valid, positive predictive values (PV) were inferior to 40%, negative PV superior to 90% and area under the receiver operating characteristic curve superior to 0.75. DISCUSSION All the existing classifications are valid to be applied in high risk clinical context and have a very high capacity to categorize as low risk those subjects that will not develop a DFU. Further research is needed in the primary care setting.
