Long-Term Intestinal Failure and Home Parenteral Support: A Single Center Experience.

Introduction: Home parenteral nutrition (HPN) and/or home parenteral hydration (HPH) are the gold-standard treatment for patients with long-term intestinal failure (IF). The authors aimed to assess the impact of HPN/HPH on nutritional status and survival of long-term IF patients, as well as HPN/HPH-related complications. Methods: This was a retrospective study including IF patients under HPN/HPH followed in a single large tertiary Portuguese hospital. The data collected included demographics, underlying conditions, anatomical characteristics, type and duration of parenteral support, IF functional, pathophysiological, and clinical classifications, body mass index (BMI) at the beginning and end of follow-up, complications/hospitalizations, current patient status (deceased, alive with HPN/HPH, and alive without HPN/HPH), and cause of death. Survival after HPN/HPH beginning, until death or August 2021, was recorded in months. Results: Overall 13 patients were included (53.9% female, mean age 63.46 years), and 84.6% of patients presented type III IF and 15.4% type II. Short bowel syndrome caused 76.9% of IF. Nine patients received HPN and 4 HPH. Eight patients (61.5%) were underweight at the beginning of HPN/HPH. At the end of follow-up, 4 patients were alive without HPN/HPH, 4 maintained HPN/HPH, and 5 died. All patients improved their BMI (mean initial BMI 18.9 vs. 23.5 at the end, p < 0.001). Eight patients (61.5%) were hospitalized due to catheter-related complications, mainly infectious (mean hospitalization episodes 2.25, mean hospital stay of 24.5 days). No deaths were related to HPN/HPH. Conclusion: HPN/HPH significantly improved IF patients' BMI. HPN/HPH-related hospitalizations were common, however causing no deaths, reinforcing that HPN/HPH is an adequate and safe therapy for long-term IF patients.

Introdução: A nutrição parentérica domiciliária (NPD) e/ou a hidratação parentérica domiciliária (HPD) constituem o tratamento gold-standard para doentes com falência intestinal (FI) crónica. O objetivo do presente estudo foi avaliar o impacto da NPD/HPD no status nutricional e sobrevivência dos doentes com FI crónica, bem como as complicações relacionadas à NPD/HPD. Métodos: Estudo retrospetivo, incluindo doentes com FI sob NPD/HPD, seguidos num hospital terciário em Portugal. Informação recolhida para cada doente: dados demográficos, patologia de base, características anatómicas, tipo e duração do suporte parentérico, classificação funcional, fisiopatológica e clínica da FI, índice de massa corporal (IMC) no início e final do seguimento, complicações/hospitalizações, estado atual do doente (falecido, vivo sob NPD/HPD e vivo sem NPD/HPD) e causa de morte. A sobrevida após início da NPD/HPD foi calculada em meses, até à data da morte ou agosto de 2021. Resultados: Incluídos 13 doentes (53.9% do sexo feminino, idade média 63.46 anos), 84.6% com FI tipo III e 15.4% com FI tipo II. A síndrome do intestino curto foi causa de 76.9% das FI. Nove doentes foram tratados com NPD e 4 com HPD. Oito doentes (61.5%) apresentavam IMC baixo no início da NPD/HPD. No final do seguimento, 4 doentes estavam vivos sem NPD/HPD, 4 mantinham NPD/HPD e 5 faleceram. Todos os doentes melhoraram significativamente o seu IMC (IMC médio no início do seguimento 18.9kg/m2 vs 23.5kg/m2 no final, p<0.001). Oito doentes (61.5%) tiveram de ser hospitalizados devido a complicações relacionadas com o cateter, sobretudo de causa infeciosa (número médio de hospitalizações por doente 2.25, duração média de internamento 24.5 dias). Não houve mortes relacionadas com a NPD/ HPD. Conclusão: A NPD/HPD melhorou significativamente o IMC dos doentes com FI. As hospitalizações relacionadas com a NPD/HPD foram comuns, contudo não causaram mortes, reforçando o facto que a NPD/HPD é uma terapêutica segura e adequada para doentes com FI crónica.

Conversational Agents for Health and Well-being Across the Life Course: Protocol for an Evidence Map.

BACKGROUND: Conversational agents, which we defined as computer programs that are designed to simulate two-way human conversation by using language and are potentially supplemented with nonlanguage modalities, offer promising avenues for health interventions for different populations across the life course. There is a lack of open-access and user-friendly resources for identifying research trends and gaps and pinpointing expertise across international centers. OBJECTIVE: Our aim is to provide an overview of all relevant evidence on conversational agents for health and well-being across the life course. Specifically, our objectives are to identify, categorize, and synthesize-through visual formats and a searchable database-primary studies and reviews in this research field. METHODS: An evidence map was selected as the type of literature review to be conducted, as it optimally corresponded to our aim. We systematically searched 8 databases (MEDLINE; CINAHL; Web of Science; Scopus; the Cochrane, ACM, IEEE, and Joanna Briggs Institute databases; and Google Scholar). We will perform backward citation searching on all included studies. The first stage of a double-stage screening procedure, which was based on abstracts and titles only, was conducted by using predetermined eligibility criteria for primary studies and reviews. An operational screening procedure was developed for streamlined and consistent screening across the team. Double data extraction will be performed with previously piloted data collection forms. We will appraise systematic reviews by using A Measurement Tool to Assess Systematic Reviews (AMSTAR) 2. Primary studies and reviews will be assessed separately in the analysis. Data will be synthesized through descriptive statistics, bivariate statistics, and subgroup analysis (if appropriate) and through high-level maps such as scatter and bubble charts. The development of the searchable database will be informed by the research questions and data extraction forms. RESULTS: As of April 2021, the literature search in the eight databases was concluded, yielding a total of 16,351 records. The first stage of screening, which was based on abstracts and titles only, resulted in the selection of 1282 records of primary studies and 151 records of reviews. These will be subjected to second-stage screening. A glossary with operational definitions for supporting the study selection and data extraction stages was drafted. The anticipated completion date is October 2021. CONCLUSIONS: Our wider definition of a conversational agent and the broad scope of our evidence map will explicate trends and gaps in this field of research. Additionally, our evidence map and searchable database of studies will help researchers to avoid fragmented research efforts and wasteful redundancies. Finally, as part of the Harnessing the Power of Conversational e-Coaches for Health and Well-being Through Swiss-Portuguese Collaboration project, our work will also inform the development of an international taxonomy on conversational agents for health and well-being, thereby contributing to terminology standardization and categorization.
