Pulmonary Metastasis in a Cardiac Angiosarcoma. Case Report and Discussion

Apresenta-se um caso clínico referente a doente de 35 anos, do sexo masculino sem antecedentes pessoais relevantes, admitido no serviço de urgência por quadro de toracalgia e tosse produtiva com alterações electrocardiográficas sugestivas de pericardite. Inicialmente admitido pelo Serviço de Cardiologia, com melhoria do quadro clínico após terapêutica anti- -inflamatória; contudo, no internamento houve como intercorrência pneumonia de provável etiologia bacteriana, complicada por derrame pleural. Após a alta,foi referenciado à consulta de pneumologia, onde se manteve o estudo etiológico do derrame persistente, tendo vindo a complicar-se o seu quadro com alterações das cavidades cardíacas e múltiplos nódulos pulmonares, sugestivos de endocardite subaguda com embolização séptica pulmonar. Internado no serviço de Pneumologia e submetido a videotoracoscopia, foi-lhe diagnosticado angiossarcoma cardíaco com metastização pulmonar. Assistiu-se a uma rápida evolução do quadro clínico, quase fulminante, com falência cardíaca e óbito do doente sem ter iniciado radioterapia ou quimioterapia adjuvante

From Eshu to Obatala: animals used in sacrificial rituals at Candomblé "terreiros" in Brazil

<p>Abstract</p> <p>Background</p> <p>The practice of sacrifice has occurred in several cultures and religions throughout history and still exists today. Candomblé, a syncretical Afro-Brazilian religion, practices the sacrificial ritual called "<it>Orô</it>" by its adherents. The present work aims to document the use of animal species in these sacrificial practices in the cities of Caruaru (PE) and Campina Grande (PB) in Norteastern Brazil, and to further understand the symbolism of these rituals.</p> <p>Methods</p> <p>Semi-structured and unstructured interviews and informal discussions were held with 11 Candomblé priests and priestesses between the months of August 2007 and June 2008. We attended rituals performed at "terreiros" where animals were sacrificed, in order to obtain photographic material and observe the procedures and techniques adopted.</p> <p>Results</p> <p>A total of 29 animal species were used during sacrificial rituals according to the priests and priestesses. These species were classified in 5 taxanomic groups: Molluscs (n = 1), Amphibians (n = 2), Reptiles (n = 2), Birds (n = 10) and Mammals (n = 14). According to Candomblé beliefs, animals are sacrificed and offered to their deities, known as orishas, for the prosperity of all life. There is a relationship between the colour, sex and behaviour of the animal to be sacrificed, and the orisha to whom the animal is going to be offered. The many myths that form the cosmogony of Candomblé can often explain the symbolism of the rituals observed and the animal species sacrificed. These myths are conveyed to adherants by the priests and priestesses during the ceremonies, and are essential to the continuation of this religion.</p> <p>Conclusion</p> <p>Candomblé is a sacrificial religion that uses animals for its liturgical purposes. The principal reason for sacrifice is to please supernatural deities known as orishas in order to keep life in harmony. This is accomplished through feeding them in a spiritual sense through sacrifice, maintaining a perfect link between men and the gods, and a connection between the material world (called <it>Aiyê</it>) and the supernatural world (called <it>Orun</it>).</p

Nutritional value of meat lipid fraction from red-legged partridge (Alectoris rufa) obtained from wild and farmed specimens

Research Areas; Agriculture, Dairy & Animal ScienceArticle in International JournalABSTRACT - The red-legged partridge (Alectoris rufa) is a feathered game species of great socioeconomic importance in its native range and also in the UK. The aim of this study was to present a detailed comparison of meat's lipid fraction obtained from wild and farm-raised specimens and simultaneously compare the breast and leg meat portions. Meat from wild specimens had a significant (P < 0.05) lower proportion of saturated fatty acid (less 5.1%) and presented better P/S and n-6/n-3 ratios, and atherogenicity index than farm-raised counterparts. The wild specimens presented significant (P < 0.001) higher contents of total vitamin E (8.8 vs. 2.2 mu g/g of fresh meat), is for that reason less prone to lipid peroxidation than farm-raised specimens. Meat portions differed significantly (P < 0.05) on total lipid and total cholesterol contents and in all partial sums of fatty acids. The breast was leaner (0.86 vs. 1.47 g/100 g of meat), with lower total cholesterol (37.5 vs. 54.7 mg/100 g of meat), lower saturated fatty acid, monounsaturated fatty acid, polyunsaturated fatty acid, and n-6 polyunsaturated fatty acid (less 0.27, 0.28, 0.10, and 0.11 g/100 g of fresh meat, correspondingly). Regarding the fatty acid ratios and lipid quality indexes, breast meat presents better n-6/n-3 ratio and atherogenicity and thrombogenicity indexes.CIISAinfo:eu-repo/semantics/publishedVersio

Determinants, Health Problems, and Food Insecurity in Urban Areas of the Largest City in Cape Verde.

Urbanization processes are intertwined with nutritional transition because there is easier access to food of low nutritional quality at reduced prices, changing dietary patterns and leading to an increase of non-communicable chronic diseases. This study aims to understand the perceptions for high blood pressure, obesity, and alcoholism, describing some interactions of these dimensions in the problem of food security in the city of Praia. A qualitative study was carried out under the framework of the research project "UPHI-STAT: Urban Planning and Health Inequalities-moving from macro to micro statistics". Ten focus groups were conducted in three urban areas with distinct characteristics in the city of Praia, with a total of 48 participants. Participants reported frequent consumption of foods with poor nutritional quality, understanding the potential danger in terms of food security in the city of Praia. Easy access to and high levels of alcohol consumption, and poor quality of traditional drinks were mentioned by participants in the study areas. The impact of the economic situation on the possibility of access to safe and healthy options emerged as a differentiating factor.publishersversionpublishe

The Effectiveness of Extra Virgin Olive Oil and the Traditional Brazilian Diet in Reducing the Inflammatory Profile of Individuals with Severe Obesity: A Randomized Clinical Trial

We analyzed the effectiveness of two nutritional interventions alone and together, EVOO and the DieTBra, on the inflammatory profile of severely obese individuals. This study was an RCT with 149 individuals aged from 18 to 65 years, with a body mass index ≥ 35 kg/m2, randomized into three intervention groups: (1) 52 mL/day of EVOO (n = 50); (2) DieTBra (n = 49); and (3) DieTBra plus 52 mL/day of EVOO (DieTBra + EVOO, n = 50). The primary outcomes we measured were the-neutrophil-to-lymphocyte ratio (NLR) and the secondary outcomes we measured were the lymphocyte-to-monocyte ratio (LMR); leukocytes; and C reactive protein (CRP). After 12 weeks of intervention, DieTBra + EVOO significantly reduced the total leucocytes (p = 0.037) and LMR (p = 0.008). No statistically significant differences were found for the NLR in neither the intra-group and inter-group analyses, although a slight reduction was found in the DieTBra group (−0.22 ± 1.87). We observed reductions in the total leukocytes and LMR in the three groups, though without statistical difference between groups. In conclusion, nutritional intervention with DietBra + EVOO promotes a significant reduction in inflammatory biomarkers, namely leukocytes and LMR. CRP was reduced in EVOO and DieTBra groups and NLR reduced in the DieTBra group. This study was registered at ClinicalTrials.gov under NCT02463435

Acute Treatment of Isolated Posterior Cerebral Artery Occlusion: Single Center Experience

Background and objectives: Randomized trials for mechanical thrombectomy (MT) excluded patients with ischemic strokes due to isolated posterior cerebral artery occlusion (IPCAO), and there is no evidence for best acute treatment strategy in these patients. We aimed to assess the effectiveness and safety of MT in acute IPCAO. Methods: We retrospectively analyzed consecutive patients with acute stroke due to IPCAO submitted to MT and/or intravenous thrombolysis (IVT), between 2015-2019. Effectiveness outcomes (recanalization rate, first-pass effect, NIHSS 24h improvement and 3-month Modified Ranking Scale - mRS) and safety outcomes (complications, symptomatic intracranial hemorrhage (SICH) and 3-month mortality) were described and compared between groups. Results: A total of 38 patients were included, 25 underwent MT and 13 had IVT alone. Successful and complete recanalization were achieved in 68% and 52% of MT patients, respectively. NIHSS improvement at 24h was found in 56% of MT patients versus 30.8% of patients submitted to IVT alone (OR [95% CI]=2.86 [0.69-11.82]) and excellent functional outcome at 3 months (mRS≤1) was achieved in 54.2% of MT patients versus 38.5% in the IVT group (OR [95% CI]=1.60 [0.41-6.32]). Complications occurred in 3 (12%) procedures and there were no SICH. Mortality at 3 months was 20% in the MT group and 15.4% in patients submitted to IVT alone. Conclusions: Our results reflect a real-world scenario in a single center and seem to support the recently growing literature showing that MT is a feasible and safe treatment in IPCAO, with favorable effectiveness.info:eu-repo/semantics/publishedVersio

Reflexiones sobre el papel de la contextualización en la enseñanza de ciencias

La importancia de la contextualización y de la discusión del papel de la ciencia en el desarrollo social y económico es innegable para la enseñanza de las ciencias. Sin embargo, esto no debe significar una negligencia ni del conocimiento teórico ni de las estrategias que forman parte de su construcción y aplicación. Así, se dibuja un peligroso cuadro cuando se asume la contextualización como el único y primordial objetivo de la educación científica. Este artículo presenta un estudio realizado con 15 alumnos del último año de la carrera en Docencia de Química, cuyos resultados evidencian una preocupante «supervaloración» de lo cotidiano en detrimento de otros aspectos igualmente importantes del conocimiento químico

Tools for analysis and conditional deletion of subsets of sensory neurons [version 1; peer review: 4 approved]

Background: Somatosensation depends on primary sensory neurons of the trigeminal and dorsal root ganglia (DRG). Transcriptional profiling of mouse DRG sensory neurons has defined at least 18 distinct neuronal cell types. Using an advillin promoter, we have generated a transgenic mouse line that only expresses diphtheria toxin A (DTA) in sensory neurons in the presence of Cre recombinase. This has allowed us to ablate specific neuronal subsets within the DRG using a range of established and novel Cre lines that encompass all sets of sensory neurons. // Methods: A floxed-tdTomato-stop-DTA bacterial artificial chromosome (BAC) transgenic reporter line (AdvDTA) under the control of the mouse advillin DRG promoter was generated. The line was first validated using a Nav1.8Cre and then crossed to CGRPCreER (Calca), ThCreERT2, Tmem45bCre, Tmem233Cre, Ntng1Cre and TrkBCreER (Ntrk2) lines. Pain behavioural assays included Hargreaves’, hot plate, Randall-Selitto, cold plantar, partial sciatic nerve ligation and formalin tests. // Results: Motor activity, as assessed by the rotarod test, was normal for all lines tested. Noxious mechanosensation was significantly reduced when either Nav1.8 positive neurons or Tmem45b positive neurons were ablated whilst acute heat pain was unaffected. In contrast, noxious mechanosensation was normal following ablation of CGRP-positive neurons but acute heat pain thresholds were significantly elevated and a reduction in nocifensive responses was observed in the second phase of the formalin test. Ablation of TrkB-positive neurons led to significant deficits in mechanical hypersensitivity in the partial sciatic nerve ligation neuropathic pain model. // Conclusions: Ablation of specific DRG neuronal subsets using the AdvDTA line will be a useful resource for further functional characterization of somatosensory processing, neuro-immune interactions and chronic pain disorders
