RESUMO

BACKGROUND: Achondroplasia is a rare genetic skeletal condition characterized by disproportionate short stature. There is limited evidence on postural control in adults with achondroplasia and how lower limb lengthening (intervention) interacts with body dynamics. This study investigated sway variability during quiet standing in adults with achondroplasia with natural growth (N) and with lower limb lengthening (LL). METHODS: Sixteen adults performed bilateral/unilateral standing tasks. Linear (total excursion, amplitude, and ellipse area) and nonlinear (sample entropy and correlation dimension) center of pressure sway metrics were analyzed in the anteroposterior/mediolateral directions. Relationships between posture metrics, strength, and physical activity were explored. Between-groups statistics were calculated. RESULTS: The LL group exhibited amplified linear sway, indicating larger postural deviations, and reduced sample entropy and correlation dimension, indicative of more rigid and repeated corrections. The N group exhibited more unpredictable and adaptive movement corrections. Numerous correlations emerged between strength and posture measures, with relationships altered by intervention. CONCLUSIONS: Adults with achondroplasia display distinct balance strategies influenced by intervention. The results indicate that LL is associated with altered variability and adaptability compared to natural development. Relationships with muscle strength spotlight a key role of muscle capacity in postural control modulation after growth alterations in this population.

RESUMO

Introduction: In 2020, the Directorate General of Health (DGS), a central service of the Ministry of Health in Portugal, approved and co-financed the first Open Dialogue program in the country. The present report aims to demonstrate the preliminary results of the first year of the project, implemented in the northern interior region of Alentejo. Methods: Seven people at the Center of Concern (PCC) and 21 family members/social networks received care through Open Dialogue; four external social workers and psychologists were also involved in the project as members of the support network. A total of 160 network meetings were undertaken, reaching as many as 27 per month in the busiest periods. Based on a previous Italian Research Protocol, developed by Pocobello et al. (non-published manuscript), quantitative and qualitative data were collected in and after the clinical meetings involving PCC and their family/social network, through a multi-method approach: clinical history interview (e.g., generic research on sociodemographic data, duration of untreated symptoms, reasons for requesting help, possible hospitalizations, and/or treatments/therapies) and the following scales applied every five sessions (e.g., CORE-OM, BSI, GAF, and LSNS-6). Results: The preliminary results indicate an improvement in global functioning and the enlargement of social network size/support, a decrease in symptoms, and a negative correlation between the number of sessions and the LSNS6. Medication use remained largely unchanged at the end of the project. Discussion: In general, even with a small sample, the results are considered satisfactory and seem to be aligned with the vast majority of Open Dialogue studies, which for several decades have consistently pointed toward better recovery rates than treatment as usual as well as increased client satisfaction. We expect that the results presented can boost further research and help strengthen the OD approach.

RESUMO

Introduction: Sorafenib was the first therapy used for systemic treatment of unresectable hepatocellular carcinoma (HCC). Multiple prognosis factors associated with sorafenib therapy have been described. Objectives: The aim of this work was to evaluate survival and time to progression (TTP) on HCC patients treated with sorafenib, and check for predictive factors of sorafenib benefit. Materials and Methods: Retrospectively, data from all HCC patients treated with sorafenib in a Liver Unit from 2008 to 2018 were collected and analyzed. Results: Sixty-eight patients were included; 80.9% were male, the median age was 64.5 years, 57.4% had Child-Pugh A cirrhosis and 77.9% were BCLC stage C. Macrovascular invasion (MVI) was present in 25% of the patients and 25% of the subjects had other extrahepatic metastasis. The median survival was 10 months (IQR 6.0-14.8) and median TTP was 5 months (IQR 2.0-7.0). Survival and TTP were similar between Child-Pugh A and B patients: 11.0 months (IQR 6.0-18.0) for Child-Pugh A and 9.0 months (IQR 5.0-14.0) for Child-Pugh B (p = 0.336). In univariate analysis, larger lesion size (LS >5 cm), higher alpha-fetoprotein (AFP >50 ng/mL), and no history of locoregional therapy were statistically associated with mortality (HR 2.17, 95% CI 1.24-3.81; HR 3.49, 95% CI 1.90-6.42; HR 0.54, 95% CI 0.32-0.93, respectively), but only LS and AFP were independent predictive factors, as shown in multivariate analysis (LS: HR 2.08, 95% CI 1.10-3.96; AFP: HR 3.13, 95% CI 1.59-6.16). MVI and LS >5 cm were associated with TTP shorter than 5 months in univariate analysis (MVI: HR 2.80, 95% CI 1.47-5.35; LS: HR 2.1, 95% CI 1.08-4.11), but only MVI was an independent predictive factor of TTP shorter than 5 months (HR 3.42, 95% CI 1.72-6.81). Regarding safety data, 76.5% of patients reported at least one side effect (any grade), and 19.1% presented grade III-IV adverse effects leading to treatment discontinuation. Conclusions: We observed no significant difference in survival or TTP in Child-Pugh A or Child-Pugh B patients treated with sorafenib, as compared to more recent real-life studies. Lower primary LS and AFP were associated with a better outcome, and lower AFP was the main predictor of survival. The reality of systemic treatment for advanced HCC has recently changed and continues to evolve, but sorafenib remains a viable therapeutic option.


Introdução: O sorafenib foi o primeiro fármaco usado em primeira linha na terapêutica sistémica do carcinoma hepatocelular (CHC) em estadio avançado. Têm sido descritos múltiplos factores modificadores de prognóstico associados à sua utilização. Objectivos: Caracterizar um grupo de doentes com CHC que realizaram terapêutica com sorafenib, estudar a sobrevivência e o tempo até progressão (TAP), e avaliar os factores preditores de benefício. Material e Métodos: Estudo retrospectivo com recolha e análise dos dados relativos a todos os doentes com CHC tratados com sorafenib numa Unidade de Hepatologia, entre 2008 e 2018. Resultados: Foram incluídos no estudo sessenta e oito doentes; 80.9% do sexo masculino, com mediana de idades de 64.5 anos, 57.4% tinham cirrose em estadio A de Child-Pugh e 77.9% apresentavam CHC em estadio C do Barcelona Clínic Liver Cancer (BCLC). A invasão macrovascular (IMV) estava presente em 25% dos doentes, e também 25% dos doentes tinha metastização extra-hepática (que não a IMV). A mediana de sobrevivência foi de 10 meses (IQR 6.0-14.8) e a mediana de TAP foi de 5 meses (IQR 2.0­7.0). A sobrevivência e o TAP foram similares nos doentes Child-Pugh A e B: 11.0 meses (IQR 6.0­18.0) para Child-Pugh A e 9.0 meses (IQR 5.0­14.0) para Child-Pugh B (p = 0.336). Na análise univariada, o tamanho da lesão >5 cm (TL), alfa-fetoproteína > 50 ng/mL (AFP) e a ausência de terapêuticas locorregionais prévias (TLP) tiveram relação estatisticamente significativa com a mortalidade (TL: HR 2.17, 95% CI 1.24­3.81; AFP: HR 3.49, 95% CI 1.90­6.42; TLP: HR 0.54, 95% CI 0.32­0.93), mas apenas o TL e AFP foram fatores preditores independentes, como mostrou a análise multivariada (TL: HR 2.08, 95% CI 1.10­3.96; AFP: HR 3.13, 95% CI 1.59­6.16). A IMV e o TL >5 cm estiveram associados com o TAP <5 meses na análise univariada (IMV: HR 2.80, 95% CI 1.47­5.35; TL: HR 2.1, 95% CI 1.08­4.11), mas apenas a IMV foi um fator preditor independente de TAP <5 meses (HR 3.42, 95% CI 1.72­6.81). Relativamente aos dados de segurança, 76.5% dos doentes relataram pelo menos um efeito lateral (qualquer grau), e 19.1% apresentaram efeitos adversos de grau III-IV, que levaram à suspensão do fármaco. Conclusões: Não foi observada diferença significativa na sobrevivência ou no tempo até progressão nos doentes Child-Pugh A ou Child-Pugh B tratados com sorafenib, quando comparado com estudos real-life recentes. Menor TL e AFP estiveram associados a melhor outcome e um valor de AFP baixo mostrou-se o principal preditor de sobrevivência. A realidade da terapêutica sistémica para o CHC avançado alterou-se recentemente e continua em mudança, mas o sorafenib permanece uma alternativa terapêutica viável.

RESUMO

Anorectal malformations are one of the most frequent congenital malformations treated by pediatric surgeons. In low-income countries, the surgical and anesthetic management of children in need of these procedures can be challenging. Limited oxygen supply, lack of equipment, especially pediatric, and intensive care units make the use of regional anesthesia appealing. We present a series of four cases of anorectal malformations corrections in Guinea Bissau, in children up to 13 months of age, under regional anesthesia and sedation with ketodex, a mixture of ketamine and dexmedetomidine (in a proportion of 1 mg to 1 µg). No child developed respiratory depression requiring airway intervention or supplemental oxygen, or had hemodynamic instability.

RESUMO

The COVID-19 pandemic resulted in severe, unprecedented changes affecting the world population. Restrictions in mobility, social distancing measures, and the persistent social alarm, during the first period of pandemic, resulted in dramatic lifestyle changes and affected physical and psychological wellbeing on a global scale. An international research team was constituted to develop a study involving different countries about eating motivations, dietary habits and behaviors related with food intake, acquisition, and preparation. This study presents results of an online survey, carried out during the first lockdown, in 2020, assessing food-related behavior and how people perceived them to change, comparatively to the period preceding the COVID-19 outbreak. A total of 3332 responses, collected from 16 countries, were considered for analysis [72.8% in Europe, 12.8% in Africa, 2.2% in North America (USA) and 12.2% in South America]. Results suggest that the main motivations perceived to drive food intake were familiarity and liking. Two clusters were identified, based on food intake frequency, which were classified as "healthier" and "unhealthier". The former was constituted by individuals with higher scholarity level, to whom intake was more motivated by health, natural concerns, and weight control, and less by liking, pleasure or affect regulation. The second cluster was constituted by individuals with a higher proportion of male and intake more influenced by affect-related motivations. During this period, a generalized lower concern with the convenience attributes of foods was noted (namely, choice of processed products and fast-food meals), alongside an increase in time and efforts dedicated to home cooking. Understanding the main changes and their underlying motivations in a time of unprecedented crisis is of major importance, as it provides the scientific support that allows one to anticipate the implications for the future of the global food and nutrition system and, consequently, to take the appropriate action.

RESUMO

BACKGROUND: Oral anticoagulants (OAC) are indicated in patients with atrial fibrillation (AF) and high risk of ischemic stroke. However, the introduction of anticoagulation in patients with AF and previous intracerebral hemorrhage (ICH) is controversial. We aimed to better understand the efficacy and safety of OAC in this context and to assess the factors that may influence this decision. METHODS: In a single-center retrospective observational study, patients with AF and ICH who survived hospitalization at a level A Stroke Unit between 2009 and 2018 were included. Patients were followed for two years after discharge. Data were collected regarding the introduction or not of OAC and the occurrence of major thrombotic/hemorrhagic events and death. RESULTS: Ninety-five patients (75.2 ± 9.9 years) were included and 40 patients (42.1%) started OAC. Patients were more likely to initiate anticoagulation if they had: mechanical prosthetic valves, previous AF (p = 0.005) and previous OAC therapy (p < 0001); and less if they had previous hemorrhagic stroke (p < 0.005). During follow-up, 10.5% had at least one major hemorrhagic event (60% anticoagulated), 20% had at least one major thrombotic event (all non-anticoagulated) and 20% died. The only factor associated with the risk of bleeding was ICH score (OR:2.49 per 1-point increase; 95%CI:1.14-5.46). Patients who initiated anticoagulation had lower mortality than non-anticoagulated (OR:0.296; 95%CI:0.090-0-975). Previous ICH and higher CHA2DS2-VASc were associated with higher mortality. CONCLUSION: In this retrospective series, anticoagulation reduced thrombotic events and overall mortality in patients admitted for ICH and AF, without a significant increase in bleeding risk.

RESUMO

BACKGROUND: Cervical spondylotic myelopathy (CSM) is one of the leading causes of degenerative cervical myelopathy and the most common cause of spinal cord dysfunction in the elderly worldwide. Although there is emerging evidence that most patients improve after surgery, the key clinical and imaging factors predicting outcome remain uncertain. Our purpose is to evaluate preoperative and postoperative morphometric parameters on magnetic resonance imaging and their relation with neurological outcome at discharge and at 12-month follow-up. METHODS: Morphometric features (volume, area, and antero-posterior diameter of the major stenotic section) were acquired by manual segmentation of the spinal canal using OsiriX open-source software and confronted with neurological outcome (at discharge and 12 months after surgery) using Nurick's scale. RESULTS: Fifty-five patients (21 females and 34 males) with a mean age of 64.89 ± 11.95 years were analyzed. Recovery ratio was 2.44% ± 2.40% at discharge and 11.74% ± 2.50% at follow-up. Statistical analysis revealed a significant difference (P < .001) between Nurick's scale at admission versus discharge, at discharge versus follow-up at 1 year, and between admission and follow-up at 1 year. Morphometric changes (difference and ratio) between preoperative and postoperative measurements were also statistically significant (P < .001, paired samples t test). When linear regression was applied, volume difference was shown to have an influence on clinical improvement (P < .05; R = 0.519). Linear regression was also applied using recovery ratio at discharge and follow-up as dependent variables, with the same conclusion: volume difference between preoperative and postoperative measurements correlates with outcome improvement at 1 year after surgery. CONCLUSIONS: Acquisition of morphometric features might be useful in predicting surgical outcome in patients with CSM. This information can be used to inform patients of their long-term postoperative prognosis in the future with more accurate and standardized measurements.

RESUMO

Transthyretin (TTR), a 55 kDa evolutionarily conserved protein, presents altered levels in several conditions, including malnutrition, inflammation, diabetes, and Alzheimer's Disease. It has been shown that TTR is involved in several functions, such as insulin release from pancreatic ß-cells, recovery of blood glucose and glucagon levels of the islets of Langerhans, food intake, and body weight. Here, the role of TTR in hepatic glucose metabolism was explored by studying the levels of glucose in mice with different TTR genetic backgrounds, namely with two copies of the TTR gene, TTR+/+; with only one copy, TTR+/-; and without TTR, TTR-/-. Results showed that TTR haploinsufficiency (TTR+/-) leads to higher glucose in both plasma and in primary hepatocyte culture media and lower expression of the influx glucose transporters, GLUT1, GLUT3, and GLUT4. Further, we showed that TTR haploinsufficiency decreases pyruvate kinase M type (PKM) levels in mice livers, by qRT-PCR, but it does not affect the hepatic production of the studied metabolites, as determined by 1H NMR. Finally, we demonstrated that TTR increases mitochondrial density in HepG2 cells and that TTR insufficiency triggers a higher degree of oxidative phosphorylation in the liver. Altogether, these results indicate that TTR contributes to the homeostasis of glucose by regulating the levels of glucose transporters and PKM enzyme and by protecting against mitochondrial oxidative stress.

RESUMO

A 55-year-old man was taken to the emergency department due to right arm weakness for the past 3 days and fever (39.5°C). There was no impaired consciousness, no history of trauma and meningeal signs were absent on physical examination. Blood analysis and inflammatory markers were not evocative of a systemic infection. A cranial CT scan was requested, revealing hypodense bilateral hemispheric subdural collections, suggestive of chronic subdural haematomas. He was submitted to surgical drainage by burr holes, which confirmed the chronic subdural collection on the left side. Unexpectedly, after dural opening on the right side, a subdural purulent collection was found, which was later confirmed as an empyema due to Escherichia coli infection. A second surgical drainage was performed by craniotomy due to recurrence of the right subdural collection. Spontaneously appearing subdural empyemas due to E. coli are extremely rare and their treatment is not always straightforward. The reported case is an example of an apparently straightforward and frequent pathology that turned out to be a challenging case, requiring a multidisciplinary approach.

RESUMO

Paragangliomas are rare, benign and slow-growing neuroendocrine tumors that can arise from the adrenal medulla (85­90%) or from the extra-adrenal paraganglia. In the central nervous system (CNS), they can be found at several sites, but more often at the cauda equina and filum terminale region, where they account for between 2.5 and 3.8% of total tumor cases of that region. There are only 8 cases described in the literature that mention the presence of the gangliocytic variant of this entity at the filum terminale. We present the case of a 41-year-old man with chronic lumbar pain refractory to medical treatment, without any associated neurological deficits. Magnetic resonance imaging (MRI) revealed an intradural, extramedullar oval lesion with regular contours and homogeneous caption of contrast at L1 level. He was submitted to surgical treatment, with complete resection of the lesion. The histological analysis revealed a gangliocytic paraganglioma of the filum terminale. At 5 years of follow-up, he remains asymptomatic and without any signs of relapse. These are lesions with an overall good prognosis with gross total resection. Although the recurrence rate is extremely low, prolonged observation is recommended due to the slow-growing nature of the tumor, being estimated that between 1 and 4% can recur even after gross total removal.

RESUMO

BACKGROUND: Solitary spinal amyloidoma (SSA) is a rare and poorly characterized disease. There are few cases described, and the knowledge of this neoplasm is limited. A more accurate description of demographics, clinical findings, and outcomes may be useful for a better understanding of this pathology, as well as therapeutic intervention, adding value to the research of localized amyloidosis. METHODS: A systematic search was carried out from when registries began until February 2020. We also include a case diagnosed and treated in our department. Descriptive statistics were used to evaluate data, demographics, clinical findings, diagnostic modalities, therapeutics, and finally neurologic outcomes. The Kaplan-Meier method was used to assess overall survival and progression-free survival. RESULTS: The final cohort comprises 35 patients. The mean age at diagnosis was 61.97 years, and 68.60% of the patients were male. SSA developed more frequently in the thoracic spine (48.60%), followed by the cervical spine (17.10%). Intradural lesions were rare, and the average neoplastic score for spinal instability was 9.5 points. The most common symptoms were impaired motor function (74.29%) and axial back pain (65.70%). After surgery, neurologic recovery was reported in 82.90% of cases. Mean progression-free survival and mean overall survival were 47.26 and 156.66 months. CONCLUSIONS: SSA is a rare subgroup of localized amyloidosis, usually being diagnosed in male patients between the sixth and eighth decades. The gold standard treatment seems to be surgical resection. SSA patients have excellent long-term survival and a low rate of local recurrence.

RESUMO

BACKGROUND AND PURPOSE: Acute ischemic stroke (AIS) severity and clinical course are less known in direct oral anticoagulants (DOAC) users. We aimed to explore the outcome of AIS in patients pretreated with vitamin-K-antagonists (VKA) and DOAC. METHODS: A retrospective study was performed. Patients pretreated with oral anticoagulants (OAC) for nonvalvular atrial fibrillation admitted for AIS in a stroke unit between 2016-01-01 and 2018-08-31 were included. The primary endpoint was mortality during the hospital stay, and secondary endpoints were neurologic improvement at stroke unit discharge and good functional outcome 90 days after AIS. RESULTS: A total of 156 patients were included (83 on VKA and 73 on DOAC). Stroke severity (defined by NIHSS on admission) was comparable in both groups (AVK 13.0 [4.0-20.0] versus DOAC 11.0 [4.0-17.0], P = .435). Infratherapeutic levels and/or inappropriate low dose of OAC was also similar between groups (P = .152) and was not associated with stroke severity (P = .631) or mortality (P = .788). VKA (OR 12.616, P = .035, 95%CI 1.19-133.64) and PH2 hemorrhagic transformation (OR 7.516, P = .024, 95%CI 1.31-43.20) were associated with higher mortality in multivariate analysis. Higher stroke severity (OR .101, P < .001, 95%CI .037-.279) and VKA usage (OR .212, P = .003, 95%CI .08-.58) were associated with worse functional outcome at 3 months. Reperfusion therapy was significantly associated with neurologic improvement during stroke unit stay (OR 3.969, P = .009, 95%CI 1.42-11.11) but not with the functional outcome (P = .063). CONCLUSIONS: Nonvalvular atrial fibrillation patients pretreated with DOAC admitted for AIS had a better outcome when compared to VKA, although stroke severity was similar between groups.

RESUMO

BACKGROUND: Systolic function recovery in patients with Heart failure (HF) with reduced ejection fraction (EF) is well recognized but not completely understood. We aimed to characterize HF patients with systolic function recovery, its prognostic impact and predictors. METHODS: We analysed patients followed in a HF clinic (2006-2015) with 2 echocardiograms performed. Partial recovery: EF recovery without attaining EF ≥ 50%; total recovery: patients reached EF ≥ 50%. Median follow-up from first echocardiogram: 69 months. Multivariate logistic regression models to determine recovery predictors. RESULTS: We analysed 304 patients with at least mild left ventricular dysfunction. During a median 34 months between echocardiogram re-evaluation 150 (49.3%) patients showed no EF recovery; 55 (18.1%) had partial recovery and 99 (32.6%) totally recovered. Mean patients age: 66; 71.1% men, high comorbidity burden; ischemic HF: 35.5%. Non-recovered patients were mostly men (80.7% vs 61.8% in partially; 61.6% in fully-recovered) with ischemic HF (46.0% vs 32.5% in partially; 21.2% in fully-recovered). Comorbidity burden, NYHA class and therapy were similar. During follow-up, 156 patients (46.7%) died. Patients with total recovery had a multivariate-adjusted 54% lower risk of dying when compared to non-recovered. Partially-recovered patients showed a non-significant adjusted 8% mortality reduction. Independent predictors of systolic function recovery were female gender(OR: 2.17, 95% CI 1.11-4.35), non-ischemic aetiology (OR: 2.78, 95% CI 1.35-5.56), and end diastolic left ventricular diameter < 60 mm (OR: 3.12, 95% CI 1.56-6.25). CONCLUSIONS: HF-recovered patients were mainly women with non-ischemic HF and smaller left ventricles. These patients had significantly better prognosis than those with persistently reduced EF.

RESUMO

Whipple's disease is a rare multisystemic infectious disease that can mimic lymphoproliferative disorders and must be considered in the differential diagnosis of febrile syndromes. The authors describe the case of a 55-year-old man who presented to the Emergency Department with dyspnoea and abdominal pain. He had a 2-month history of fever, night sweats, asthenia and unintentional weight loss. Upon clinical examination he had bilateral inguinal lymphadenopathy. Blood tests showed iron-deficit anaemia and high C-reactive protein. Abdominal ultrasound showed mesenteric and iliac adenopathies and hepatosplenomegaly. The patient was admitted to the Internal Medicine department for additional testing. Flow cytometry analysis of peripheral blood showed CD5-positive monoclonal B-cell expansion. Excisional biopsy of a retroperitoneal adenopathy guided by computed tomography showed periodic acid-Schiff-positive bacilli inside the macrophages, further identified as Tropheryma whipplei through polymerase chain reaction. Bone marrow biopsy showed a scarce positive CD5 lymphoid population and haematopoietic alterations related to infection. The patient started treatment for T. whipplei with complete symptom resolution. This is the first case describing the simultaneous diagnosis of Whipple's disease and chronic lymphocytic leukaemia in a patient with constitutional symptoms, fever and lymphadenopathies. LEARNING POINTS: Whipple's disease can mimic lymphoproliferative disorders and should be considered in the differential diagnosis of lymphadenopathy and fever, even in the absence of gastrointestinal symptoms.Most patients with chronic lymphocytic leukaemia are asymptomatic, but a minority have B symptoms and increased risk of infections.An accurate clinical history and differential diagnosis are fundamental; if the authors had not had a high level of suspicion, this patient could have been diagnosed with just chronic lymphocytic leukaemia and may have died if Whipple's disease had been left untreated.

RESUMO

Tuberculosis remains a worldwide public health problem. Cervical tuberculous lymphadenitis (TBL) or scrofula is the most common form of extrapulmonary tuberculosis, affecting the cervical lymph nodes. We report the case of a 93-year-old woman presenting with cervical adenopathies with 3 months duration. Fine needle aspiration (FNA) biopsy yielded a noncaseous granulomatous process, but was negative for Mycobacterium tuberculosis (MT). As the adenopathies had grown, an excisional biopsy was performed. An extensive study of infectious aetiologies was performed, including for MT, with a negative outcome. Owing to the persistence of cervical lymphadenitis with caseous granulomas, a diagnosis of TBL was strongly suspected and presumptive treatment was initiated. Afterwards, diagnostic confirmation was obtained by isolation of MT in the lymph node culture. The patient presented a favourable clinical outcome. This case highlights that a high index of suspicion is essential for the diagnosis of TBL, especially in the elderly, and emphasizes the importance of pursuing diagnostic confirmation, in which FNA and excisional biopsy plays a key role. LEARNING POINTS: The diagnosis of tuberculous lymphadenitis should be considered in all patients presenting with cervical adenopathies, especially in endemic areas, irrespective of the patient's age.A high index of suspicion is essential for the diagnosis due to the wide range of conditions that can mimic the disease.Fine needle aspiration biopsy is appropriate as an initial diagnostic approach, with excisional biopsy recommended when the former is not diagnostic.

RESUMO

Resumo Neste artigo teórico, partimos do princípio de que os processos humanos de significação e de conhecimento se consubstanciam e se desenvolvem em interdependência com os outros, para abordarmos a identidade pessoal como um espaço dialógico entre um Eu e um Outro (uma pessoa, um grupo, uma comunidade, uma sociedade), dinamicamente regulado por afetos. A inerência dialógica da vida psicológica é abordada - i.e., o papel dos outros na constituição da subjetividade humana - e, particularmente, as dimensões afetivas e motivacionais desse processo.


Abstract In this theoretical paper we assume that human processes of meaning-making and knowledge are embodied and developed in interdependence with the Other(s) in order to approach personal identity as a dialogical space between the I and the Other (an I-position, a person, a group, a community, a society) dynamically regulated by affection. The dialogical inherence of psychological life is addressed, i.e., the role of otherness in the constitution of human subjectivity and particularly the affective and motivational dimensions of this process.

RESUMO

Nontargeted late effects of radiation include an increased risk of cardiovascular disease, although this is still debatable in the context of low-dose radiation. Tinea capitis patients treated in childhood with X rays to induce scalp epilation received a low dose of radiation to their carotids. To better clarify this issue, we evaluated carotid atherosclerosis in a cohort of such patients treated in 1950-1963 in Portugal. A group of 454 individuals randomly chosen from previously observed Portuguese tinea capitis patients and a control group mainly composed of their spouses (n = 280) were enrolled. Cardiovascular risk factors such as waist circumference, body mass index, blood pressure and tobacco consumption, as well as biochemical measurements were obtained. Ultrasound imaging of carotid arteries for intima media thickness and stenosis evaluation were performed according to a standardized protocol. In comparison to the control group, the irradiated cohort members were significantly older, more frequently never smokers, hypertensive, and presented higher glycated hemoglobin and alkaline phosphatase levels. In addition, the irradiated cohort showed a higher frequency of carotid stenosis ≥30% than the nonirradiated group (13.9% vs. 10.7%), although this was not significant ( P = 0.20). Stenosis was ≥50% in 2.9% of the irradiated group and 0.4% of the nonirradiated group ( P = 0.02). Likewise, the frequency of intima media thickness ≥1 mm was significantly higher in the irradiated group (16.8% vs. 10.7%; P = 0.02). Multivariate analysis, including other cardiovascular risk factors, showed that exposure to low-dose radiation increased the risk of carotid stenosis by ≥50% [odds ratio (OR) = 8.85; P = 0.04] and intima media thickness by ≥1 mm (OR = 1.82; P = 0.02). These findings confirm that low-dose exposure is a risk factor of carotid atherosclerotic disease.

RESUMO

The aim of the present study was to test whether perceived burdensomeness and thwarted belongingness are related to suicide ideation, when controlling for depressive symptoms. The sample consisted of elderly patients recovering from acute medical conditions who were recruited in a medical recovery clinic. Results demonstrated that depressive symptoms and thwarted belongingness related to the suicide ideation item of the Beck Depression Inventory-II, used as an indicator of suicide ideation. Depressive symptoms and thwarted belongingness also discriminated between participants with suicide ideation and participants without suicide ideation as defined by suicide items of the Symptom-Driven Diagnostic System for Primary Care. Results are discussed in terms of potential cultural influences, and clinical implications are highlighted.

RESUMO

The aim of the current study was to assess suicide ideation in a sample of older adults recovering from acute conditions in a clinical recovery facility of the Portuguese Red Cross. Four indicators of suicide ideation were used. Clinical, contextual, and psychological variables-namely, previous suicide attempts, death of a family member by suicide, loneliness, and interpersonal needs-were also tested to determine whether they were related to suicide ideation. Findings show suicide ideation is frequent at admission and related to patients' previous suicide attempts. Death of a family member by suicide and patients' functional dependency are related to some indicators of suicide ideation, and loneliness and interpersonal needs are important psychological variables relating to suicide ideation. Interpersonal needs were related to suicide ideation even after controlling for previous suicide attempts. Implications of the results for clinical practice are discussed.

RESUMO

The present study assessed the impact of suicide and distress on suicidal ideation in a sample of 93 Portuguese family members bereaved by suicide. A control community sample of 102 adults also participated. After controlling for educational level, those bereaved by the suicide of a family member were found to have higher levels of suicidal ideation. Forty-two percent of family members had Suicide Ideation Questionnaire scores at or above the cutoff point. General distress, depression, anxiety, and hostility related to suicidal ideation, whereas time since suicide also interacted with general distress and depression in predicting suicidal ideation.
