A pistrinum in the ager of Olissipo. The artisanal complex of the rural settlement of Freiria (Cascais, Portugal)
Se presentan las evidencias de una instalación
productiva vinculada al artesanado alimentario. Esta se ubica
en la parte artesanal del asentamiento rural de Freiria (Santo
Domingo de Rana, Cascais). Además de un análisis arquitectónico
y diacrónico del espacio se estudian funcionalmente
todas sus partes intentando definir ante qué estamos y la función
artesanal a la que se asocia. También se plantea una
aproximación cronológica a este lugar que se alza como un
unicum en el extremo más occidental de la provincia de la
Lusitania.This paper presents the evidences of a productive
installation linked to the food crafts. This is located in the rustic
part of the rural settlement of Freiria (Santo Domingo de
Rana, Cascais). In addition to an architectural and diachronic
analysis of the space, all its parts are studied functionally, trying
to contribute its significance to the artisanal process to
which it is associated. In addition, a chronological approach
to this unicum place in the westernmost tip of the province of
Lusitania, is proposed
MONITORIZAÇÃO POLISSONOGRÁFICA – ASPECTOS GERAIS
Polysomnography is a method to evaluate sleep that involves measurement of several physiological parameters related to time, when a patient is put to sleep at night or day.These parameters should be chosen concerning the clinical symptoms of the patient. The tests are generally performed in sleep laboratories assisted by a trained technician. The technician or a sleep medicine specialist will review the data to perform sleep staging and events identification. The findings will be analyzed with the help of a sleep analysis software and interpreted by the sleep specialist in the light of the patient’s symptoms. Not all sleep problems demands a polysomnography to be performed. The American Academy of Sleep Medicine (AASM) is an organization with many professionals and societies that are involved in basic and clinical assessment of sleep and sleep disorders. It has an official website (www.aasmnet.org) where many practice standards and reviews of polysomnography and related techniques indications can be obtained, as well as information about sleep disorders. Polysomnography is a constantly evolving technique as long as new concepts and new technologies are developed and incorporated.A polissonografia é uma técnica que faz o registro gráfico de múltiplas variáveis fisiológicas ao longo do tempo de sono, e este registro pode ser feito tanto no período noturno quanto diurno. As variáveis a serem registradas pelo exame devem ser escolhidas conforme a suspeita clínica relacionada aos sintomas do paciente. Os exames polissonográficos geralmente são feitos em laboratórios especializados, já que os exames são acompanhados durante todo o tempo por um técnico treinado. Um especialista ou técnico treinado em polissonografia irá analisar visualmente todos os dados e marcar os eventos pertinentes para que estes sejam colocados em tabelas e/ou gráficos pelo software de análise. Os achados do exame serão então interpretados pelo especialista em sono à luz dos dados clínicos do paciente. Nem todo tipo de distúrbio do sono necessita ser investigado com a polissonografia. A Academia Americana de Medicina do Sono (AASM) é uma organização que engloba inúmeros profissionais de várias especialidades médicas que lidam com distúrbios do sono (neurologistas, pneumologistas, psiquiatras, otorrinolaringologistas e outros) e publica em seu site oficial (www.aasmnet.org) diretrizes para as indicações do exame além de uma série de outras normatizações, revisões e informações sobre doenças do sono. O exame é uma técnica em evolução e vem sendo aprimorada a cada dia à medida que novos conceitos e novas tecnologias são incorporados e desenvolvidos
Intra-abdominal desmoid tumors in familial adenomatous polyposis: How much do clinical and surgical variables interfere with their development?
Objective: Familial Adenomatous Polyposis is a complex hereditary disease that exposes the carrier to a great risk of Colorectal Cancer (CRC). After prophylactic surgery, intra-abdominal desmoid tumors are known to be one the most important cause of death. Therefore, recognition of increased-risk patients and modification of operative strategy may be crucial.
Aim: The objective of this study was to estimate the desmoid tumor risk in relation to various surgical and clinical variables.
Methods: Patients who had undergone polyposis since 1958 were included in the study. After exclusion criteria were met, those who had developed desmoid tumors were selected to undergo further evaluation.
Results: The study revealed that the risk of developing desmoid tumors was associated with various factors such as sex ratio, colectomy, and reoperations. On the other hand, the type of surgery, family history, and surgical approach did not affect the risk of developing desmoid tumors. The data collected from 146 polyposis patients revealed that 16% had desmoid polyps. The sex ratio was 7:1, and the median age at colectomy was 28.6 years. Family history, multiple abdominal operations, and reoperations were some of the characteristics that were common in desmoid patients.
Conclusion: Recognition of clinical (female sex) and surgical (timing of surgery and previous reoperations) data as unfavorable variables associated with greater risk may be useful during the decision-making process

Pasantías internacionales en Bibliotecología y Ciencias de la Información una oportunidad para el diálogo de saberes
Student mobility carried out through international internships is, in the academic context, an opportunity to strengthen disciplinary knowledge, explore a particular territory and learn about cultural diversity. These formative experiences, considered through an intercultural analytical framework, are an opportunity to think about strengthening work networks and global citizenship. The Escuela Interamericana de Bibliotecología, after 65 years of existence and an inter-American character, has been a pioneer in mobility processes in its discipline; It has received professionals and students from different latitudes. This reflective article recovers the experience and gains that some of the international internships that the School has hosted have meant in recent years, which have allowed it to position itself in tune with its inter-American identity, as well as strengthen work networks in the region

Prognostic factors affecting outcomes in multivisceral en bloc resection for colorectal cancer
OBJECTIVES: This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer. METHODS: Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective database. Clinical and pathological factors, perioperative morbidity and mortality and outcomes were obtained from medical records. Estimated local recurrence and overall survival were compared using the log-rank method, and Cox regression analysis was used to determine the independence of the studied parameters. ClinicalTrials.gov: NCT02859155. RESULTS: The median age of the patients was 60 (range 23-86) years, 66.7% were female, 80% of tumors were located in the rectum, 11.4% had stage-IV disease, and 54.3% received neoadjuvant chemoradiotherapy. The organs most frequently resected were ovaries and annexes (37%). Additionally, 30.5% of patients received abdominoperineal resection. Invasion of other organs was confirmed histologically in 53.5% of patients, and R0 resection was obtained in 72% of patients. The overall morbidity rate of patients in this study was 37.1%. Ureter resection and intraoperative blood transfusion were independently associated with an increased number of complications. The 30-day postoperative mortality rate was 1.9%. After 27 (range 5-57) months of follow-up, the mortality and local recurrence rates were 23% and 15%, respectively. Positive margins were associated with a higher recurrence rate. Positive margins, lymph node involvement, stage III/IV disease, and stage IV disease alone were associated with lower overall survival rates. On multivariate analysis, the only factor associated with reduced survival was lymph node involvement. CONCLUSIONS: Multivisceral en bloc resection for primary colorectal cancer can be performed with acceptable rates of morbidity and mortality and may lead to favorable oncological outcomes
Mercury distribution in key tissues of fish (Liza aurata) inhabiting a contaminated estuary-implications for human and ecosystem health risk assessment
This study brings a new viewpoint based on multiple-tissue analyses to form the basis for a predictive mode of mercury accumulation dynamics in fish body under field conditions. Total mercury (T–Hg) was determined in key tissues of Liza aurata captured along an estuarine contamination gradient, displaying the following hierarchy: kidney > liver > muscle > brain > gills > blood. Brain was the tissue that better reflected the mercury contamination extent, closely followed by liver and muscle. Organic mercury (O–Hg) measured in muscle and liver represented more than 85% and less than 30% of the T–Hg, respectively. The lowest O–Hg percentage was found in the most contaminated area, for both muscle and liver. Mercury distribution and accumulation patterns showed dependence on the specific tissue. The high mercury levels found in organs involved in vital physiological processes point out the risk to autochthonous fish fauna. Human risk associated to the ingestion of fish living in the surveyed areas cannot be excluded
Brazilian guidelines for the diagnosis of narcolepsy
Este artigo relata as conclusões da reunião de consenso com médicos especialistas sobre diagnóstico de narcolepsia baseada na revisão dos artigos sobre narcolepsia listados no Medline entre 1980 e 2010. A narcolepsia é uma doença crônica de início entre a primeira e segunda décadas de vida do indivíduo. Os sintomas essenciais são cataplexia e sonolência excessiva. A cataplexia é definida como episódios súbitos, recorrentes e reversíveis de fraqueza da musculatura esquelética desencadeados por situações de conteúdo emocional. Os sintomas acessórios são alucinações hipnagógicas, paralisia do sono e sono fragmentado. Critérios de diagnóstico clínico de acordo com a Classificação Internacional dos Transtornos do Sono são de sonolência excessiva e cataplexia. Recomenda-se a realização de polissonografia seguida do teste de latência múltipla do sono em um laboratório de sono para confirmação e diagnóstico de comorbidades. Quando não houver cataplexia, deve haver duas ou mais sonecas com sono REM no teste de latência múltipla do sono. Tipagem HLA-DQB1*0602 positiva com níveis de hipocretina-1 abaixo de 110pg/mL devem estar presentes para o diagnóstico de narcolepsia sem cataplexia e sem sonecas com sono REM.This manuscript contains the conclusion of the consensus meeting on the diagnosis of narcolepsy based on the review of Medline publications between 1980-2010. Narcolepsy is a chronic disorder with age at onset between the first and second decade of life. Essential narcolepsy symptoms are cataplexy and excessive sleepiness. Cataplexy is defined as sudden, recurrent and reversible attacks of muscle weakness triggered by emotions. Accessory narcolepsy symptoms are hypnagogic hallucinations, sleep paralysis and nocturnal fragmented sleep. The clinical diagnosis according to the International Classification of Sleep Disorders is the presence of excessive sleepiness and cataplexy. A full in-lab polysomnography followed by a multiple sleep latency test is recommended for the confirmation of the diagnosis and co-morbidities. The presence of two sleep-onset REM period naps in the multiple sleep latency test is diagnostic for cataplexy-free narcolepsy. A positive HLA-DQB1*0602 with lower than 110pg/mL level of hypocretin-1 in the cerebrospinal fluid is required for the final diagnosis of cataplexy- and sleep-onset REM period -free narcolepsy
