[Anemia in Chronic Kidney Disease: The State of the Art]. / Anemia da Doença Renal Crónica: O Estado da Arte.

The aging of the population has led to an increased prevalence of chronic diseases such as chronic kidney disease. Anemia is one of the most frequent complications of chronic kidney disease, with an impact not only on the quality of life but also on the patient's prognosis and associated costs. Knowledge in this therapeutic area has increased significantly: from the appearance of recombinant erythropoietin in 1989, through the use of increasing doses of parenteral iron and, more recently, to new molecules such as hypoxia-inducible factor inhibitors. The aim of this article is to present a pragmatic review of the state of the art in the epidemiology, pathophysiology, diagnosis and treatment of anemia associated with chronic kidney disease.

O envelhecimento populacional tem-se traduzido no aumento de prevalência de doenças crónicas como a doença renal crónica. A anemia é uma das complicações mais frequentes da doença renal crónica, com impacto não só na qualidade de vida como no prognóstico do doente e nos custos associados. O conhecimento nesta área terapêutica tem aumentado de forma significativa: desde o aparecimento da eritropoietina recombinante em 1989, passando pelo uso de doses crescentes de ferro parentérico e, mais recentemente, a novas moléculas como os inibidores do hypoxia-inducible factor. Os autores pretendem rever, de uma forma pragmática, o estado da arte da anemia associada à doença renal crónica, desde a epidemiologia, à fisiopatologia, ao diagnóstico e ao tratamento.

Improving Awareness about Patient Blood Management in Portugal: A Call for Action Arising from a Delphi Panel.

INTRODUCTION: Anaemia and iron deficiency are associated with increased mortality and poor surgical outcomes. Consensus in their definitions is expected to optimize their management, which is encompassed by patient blood management, providing patient-centred care while improving patient safety and clinical outcomes. Patient blood management implementation is even more relevant in contingency times and faces barriers due to lack of standardization, among others. The aim is to establish a consensus on these diagnoses and implement patient blood management principles in clinical practice in Portugal. MATERIAL AND METHODS: Eight experts in Transfusion Medicine, Haematology, Anaesthesiology, Internal Medicine, and Obstetrics/Gynaecology were assembled; a focus group was conducted, defining 33 statements. A Delphi panel was conducted, with experts from the clinical specialities named above as well as from General Surgery, Urology, and Orthopaedics. RESULTS: The Delphi panel's rounds had 70 (Round 1) and 46 (Round 2) respondents. Specialists were consensual in only two statements, on the existence of a preoperative patient blood management consultation for candidates to elective surgeries in which the use of blood derivatives is anticipated and, on the importance of the correction of postoperative anaemia and iron deficiency. Of the remaining 31 statements, 27 reached high agreement or disagreement by the respondents. CONCLUSION: Consensus was reached in only two (6%) of the 33 statements. There was a consensual agreement on the relevance of establishing patient blood management as the standard of care and of valuing preoperative and postoperative patient blood management interventions. Nevertheless, our results point to the lack of awareness regarding patient blood management principles - which could result in better postoperative outcomes, shorter hospitalizations, reduced costs and increased availability of beds. Training and literacy initiatives could help further implement patient blood management standards in Portuguese hospitals.

Introdução: A anemia e ferropenia estão associadas a um aumento da mortalidade e a piores resultados no período pós-operatório. Consensualizar as suas definições permitirá otimizar a sua gestão. O patient blood management engloba essa gestão, com relevo acrescido em situações de contingência, focado nos cuidados centrados no doente e na melhoria da segurança e dos outcomes. As barreiras à implementação de princípios patient blood management prendem-se, entre outras, com falta de padronização. Pretende--se estabelecer um consenso sobre estes diagnósticos e implementação de patient blood management na prática clínica em Portugal. Material e Métodos: Foram reunidos oito especialistas em Imuno-hemoterapia, Hematologia Clínica, Anestesiologia, Medicina Interna e Obstetrícia/ Ginecologia. Foi realizado um focus group, onde foram definidas 33 afirmações. Além disso, foi realizado um painel Delphi, com especialistas das áreas mencionadas acima, assim como de Cirurgia Geral, Urologia e Ortopedia. Resultados: As duas rondas do painel Delphi tiveram, respetivamente, 70 e 46 respondedores. Estes foram consensuais em apenas duas afirmações, na existência de consulta pré-operatória de patient blood management para os candidatos a cirurgias eletivas em que se antecipa o uso de hemoderivados e, na importância da correção da anemia e ferropenia pós-operatórias. Das 31 afirmações restantes, 27 atingiram alta concordância ou discordância pelos respondentes. Conclusão: Foi alcançado consenso em apenas duas (6%) das 33 afirmações. Houve consenso sobre a relevância de estabelecer o patient blood management como standard of care e a valorização das intervenções de patient blood management pré e pós-operatórias. No entanto, os resultados indiciam falta de consciencialização sobre os princípios de patient blood management ­ que poderiam levar a melhores resultados pós-operatórios, com redução do tempo de hospitalização e dos custos e maior disponibilidade de camas. Iniciativas de formação e literacia poderiam ajudar a uma melhor implementação dos princípios de patient blood management nos hospitais portugueses.

Screening for Anemia and Iron Deficiency in the Adult Portuguese Population.

Anemia and iron deficiency (ID) can impair quality of life and socioeconomic development. We evaluated the prevalence of anemia and ID in the adult Portuguese population in real-life contexts by gender, age, and pregnancy status. We performed a cross-sectional screening in adult individuals in mainland Portugal from 2013 to 2017. Participants completed a survey about demographics and signs or symptoms compatible with anemia, and ID and hemoglobin and ferritin concentrations were determined by point-of-care tests. We estimated and compared prevalence ratios (PR) of anemia and ID using Poisson regression with robust variance and the Wald chi-square test. We collected data from 11,030 individuals (26% men, 64% nonpregnant women, and 10% pregnant women). We found anemia in 51.8% (95% CI 50.1-53.4%) of nonpregnant women in fertile age, 46.6% (95% CI 44.7-48.6%) of nonpregnant women >51 years, 38.2% (95% CI 35.4-41.1%) of pregnant women, and 33.3% (95% CI 31.6-35.1%) of men. The prevalence of ID was 72.9% (95% CI 71.4-74.4%) in nonpregnant women in fertile age, 50.5% (95% CI 48.5-52.4%) in nonpregnant women >51 years, 94.8% (95% CI 93.3-96.0%) in pregnant women, and 28.9% (95% CI 27.3-30.6%) in men. We found significant associations between the prevalence of anemia or ID and nonpregnant women (PR: 1.50, 95% CI 1.42-1.59 or PR: 2.21, 95% CI 2.09-2.35, respectively), manifestation of signs or symptoms (PR: 1.19, 95% CI 1.53-1.23 or PR: 1.22, 95% CI 1.18-1.26), pregnant women (PR: 0.74, 95% CI 0.68-0.80 or PR: 1.30, 95% CI 1.27-1.33), and nonpregnant women ≤51 years (PR: 1.11, 95% CI 1.06-1.17 or PR: 1.42, 95% CI 1.36-1.48). In conclusion, anemia and ID represent moderate to severe public health problems, particularly among women in fertile age and in 3rd trimester, of pregnancy emphasizing the need to raise the public and health professionals' awareness of these problems and their prevention, diagnosis, and treatment.

How the Location of Intracavitary Lesions Influences Pain during Office Hysteroscopy.

STUDY OBJECTIVE: To assess how the location of intracavitary lesions during office hysteroscopy influences pain scores. DESIGN: Cohort study. SETTING: Department of Obstetrics and Gynecology, Hospital das Forças Armadas, Lisbon, Portugal. PATIENTS: Two hundred ninety-eight patients undergoing operative office hysteroscopy. INTERVENTIONS: Pain intensity was assessed by patients using a numeric rating scale (0-10) 10 minutes after hysteroscopy. MEASUREMENTS AND MAIN RESULTS: Statistical analysis assessed the association between pain score and clinical, obstetric, and gynecologic history. Associations with procedure-related factors were also assessed. Lesion location did not influence the perception of pain in the current sample. Hysteroscopic anesthesia allowed for a significant reduction in pain scores, regardless of lesion location. Multivariate analysis revealed that only the type of operative procedure and operating time significantly influenced pain scores. CONCLUSION: Hysteroscopic anesthesia allows for a well-tolerated procedure, regardless of lesion location during office hysteroscopy. Lesion location should not be regarded as a technical limitation.

In the present article, regarding a clinical case of Thrombasthenia of Glanzmann with severe anaemia by menometrorrhagia, the authors propose the vaginal hysterectomy and the administration of the recombinant factor VIIa on the immediate pre and postoperative as effective therapeutical alternatives.

[Herpes gestationis]. / Herpes gestationis.

Herpes Gestationis is a serious dermatological disease, albeit rare, associated to pregnancy or to the trophoblast diseases. Contrary to what the name suggests, it is not a viral disease but an auto-immune disease. We present the clinical case of a 38 year-old woman to whom a case of Herpes Gestationis was diagnosed when she was 15 weeks pregnant and whom has been treated with corticosteroids and antihistamine's showing positive results and without major complications for the mother or the embryo. The authors are undertaking a review of the existing literature, based on this clinic case.
