ABSTRACT

As other European countries, France is experiencing a resurgence of pertussis in 2024. Between 1 January and 31 May 2024, 5,616 (24.9%) positive Bordetella pertussis qPCR tests were identified, following a 3-year period of almost null incidence. Of 67 cultured and whole genome sequenced B. pertussis isolates, 66 produced pertactin and 56 produced FIM2, in contrast to pre-COVID-19 years. One isolate of genotype Bp-AgST4 was resistant to macrolides. Pertussis resurgence may favour isolates that produce FIM2 and pertactin.

ABSTRACT

Serous tubal intraepithelial carcinoma, serous tubal intraepithelial lesions (STILs), and the p53 signature are considered to be related to precursor lesions of high-grade serous carcinomas (HGSCs). However, the clinical significance and prognostic implications of these lesion types are currently unknown. We diagnosed three patients with STILs according to the morphological evaluation criteria and combined this with p53 and Ki-67 immunostaining. One patient had an HGSC of the ovary that was incidentally discovered at the time of ovarian cyst resection, and the HGSC in the other two patients was characterized after they underwent risk-reducing salpingo-oophorectomy. Herein, we present a report of three patients with STILs diagnosed based on clinical data and pathological findings, along with a review of the literature.

ABSTRACT

OBJECTIVE: The objective of this study was to develop a home exercise rehabilitation management program for elderly stroke patients based on the Functional Independence Measure (FIM) score and assess its effectiveness through practical application. METHODS: A prospective asynchronous controlled trial was conducted involving 290 elderly stroke patients, with 145 assigned to the control group and 145 to the intervention group. The control group received standard home rehabilitation instructions, while the intervention group followed a home exercise rehabilitation program guided by FIM scores. The program was developed through research group discussions, evidence-based literature review, and expert input. The efficacy of the program was evaluated by comparing self-care ability and exercise function between the two patient groups. RESULTS: After 4 and 8 weeks of intervention, the motor assessment scale (MAS), Barthel Index scores and Mini-Mental State Examination (MMSE) of the intervention group were higher than those of the control group, and the modified Rankin scale (mRS) was lower than this of the control group (P < 0.05). CONCLUSION: The home exercise rehabilitation management program for elderly stroke patients based on FIM scores was developed in a scientifically sound manner. This program holds significant theoretical implications for enhancing the home exercise regimen of elderly stroke patients and facilitating the rehabilitation of their limb functions.

ABSTRACT

A vida frenética, principalmente nos grandes centros urbanos, dificulta, para algumas pessoas, a realização de atividade física de forma regular (3-5 vezes por semana). Todavia, a possibilidade de realizar essas atividades em um ou dois dias da semana pode ser uma alternativa bastante interessante, uma vez que este padrão de atividade física tem sido associado a menor mortalidade por todas as causas, cardiovasculares e câncer. Nesta breve revisão narrativa, abordaremos os principais estudos científicos sobre os "Guerreiros de Fim de Semana" e sua relação com os benefícios e riscos à saúde. Certamente, a incorporação desse padrão de atividade física nas recomendações e orientações futuras promoverá melhora das condições de saúde e auxiliará o poder público a adequar as estratégias de combate ao sedentarismo.

ABSTRACT

Whopping cough (or Pertussis) is an acute infectious respiratory disease caused by Bordetella pertussis bacteria. The disease is highly transmissible and can be fatal in children under two years old. Since the introduction of vaccine immunization in 1940, Pertussis incidence decreased worldwide. In Brazil, the immunization was introduced in 1977 using the whole cell (wP) vaccine. Despite the high vaccination coverage, an unexpected increase in the number of observed Pertussis cases was observed in 2012. In this year, 2257 cases were reported exceeding the average incidence rate of <1000 cases per year until 2010. This outbreak reached a peak level in 2014 and ended in 2018 according to the Brazilian National Surveillance System (SINAN). To understand the relationship between the outbreak and the vaccination, bacterial isolates (n = 136) from the Brazilian Midwest region obtained during the outbreak were submitted to genotyping of two vaccine loci: ptxP and fim3. Most of isolates (102) were obtained from nursing children (29 days to 2 years old). Genotyping of 94 isolates revealed that fim3-24/ptxP-3 was the most prevalent genotype (68%) associated with the outbreak peak. Two additional genotypes were also observed: fim3-1/ptxP-3 (15%) and fim3-3/ptxP-3 (17%). Conversely, the fim3-1/ptxP-2 genotype, which is harbored by the strain used in the wP vaccine (Bp137), was not observed. These results showed that B. pertussis circulating strains in the outbreak analyzed were different from the strain used for Pertussis immunization in Brazil. These observations provide insights that could be used to target vaccination programs to prevent future whooping cough outbreaks in Brazil.

ABSTRACT

Guillain-Barré syndrome is a polyneuropathy that can be caused by an autoimmune condition or a bacterial infection. In typical GBS cases, there is hypo- or areflexia, symmetrical limb weakness that worsens within four weeks of the symptoms. The facial nerve is involved in this situation, which results in weak facial muscles, which, in turn, affect facial emotions and movements. In this case study, a 21-year-old athlete who suffered from unexpected weakness that resulted in quadriplegia had goal-oriented physical therapy treatment designed for the patient, who recovered quickly. This case study aims to emphasize how goal-oriented physical therapy treatment can help patients recover quickly.

ABSTRACT

The Focused Impedance Method (FIM) is a new technique of electrical bioimpedance measurements in the human body. The idea originated in Bangladesh and provides an opportunity for localized measurement of bioimpedance down to reasonable depths from the body surface using skin surface electrodes. This has potential applications for physiological studies of targeted organs in the body and in detecting or diagnosing diseases and disorders. FIM is based on the age-old Tetra-Polar Impedance Measurement (TPIM) but provides a few significant improvements. Technology must be developed indigenously to obtain long-term benefits, particularly in Low and Medium Income countries (LMIC). This paper presents an experimental sensitivity study of the six-electrode version of the Focused Impedance method (FIM-6) with the circuit and phantom indigenously designed in Nepal. The work involved sensitivity studies of both FIM-6 and TPIM with the necessary circuit blocks developed through experimental validation. The sensitivity studies were performed on a simple 2D phantom with different electrode arrangements for FIM-6 and linear TPIM. A cylindrical object was placed at different positions for this study. The FIM-6 gave a high sensitivity in the central part, which remained almost constant within a small region that may be termed as the focused region. On the other hand, TPIM results fell off sharply away from the central point, making it unsuitable for practical measurements on target organs. Besides, there were areas with large negative sensitivities in TPIM, which were much smaller in FIM. The results obtained through this work clearly show the improvement offered by FIM over TPIM.

ABSTRACT

BACKGROUND AND OBJECTIVES: It is well known that more than 40% of patients in the convalescent rehabilitation settings suffer from malnutrition, and that appropriate nutrition management can improve rehabilitation outcomes. METHODS AND STUDY DESIGN: In this study, we used a change in motor score of Functional Independent Measure (FIM-M) of convalescent rehabilitation to investigate whether daily energy intake could influence the rehabilitation outcomes. Of the 217 patients hospitalized in our convalescent rehabilitation ward (CRW) between September 2016 and February 2017, 162 met the eligibility criteria for this study. RESULTS: For a 25 kcal/ ideal body weight (IBW)/day cutoff point, 76 patients consumed more than 25 kcal/IBW/day of energy (H-E group), and 86 patients consumed up to 25 kcal/IBW/day of energy (L-E group). Patients in the L-E group had poorer nutritional status than those in the H-E group at CRW admission. Moreover, patients in the L-E group lost some body weight (BW) during hospitalization, whereas patients in the H-E group gained some BW. Furthermore, the FIM-M efficiency in the L-E group was significantly lower than that in the H-E group. CONCLUSIONS: We concluded that appropriate nutritional management given to rehabilitation patients for adequate energy intake to maintain or gain their BW could maximize the outcome of convalescent rehabilitation.

ABSTRACT

AIMS: This research aims to construct and verify an accurate nomogram for forecasting the 3-, 5-, and 7-year outcomes in pediatric patients afflicted with spinal cord injury (SCI). METHODS: Pediatric patients with SCI from multiple hospitals in China, diagnosed between Jan 2005 and Jan 2020, were incorporated into this research. Half of these patients were arbitrarily chosen for training sets, and the other half were designated for external validation sets. The Cox hazard model was employed to pinpoint potential prognosis determinants related to the American Spinal Injury Association (ASIA) and Functional Independence Assessment (FIM) index. These determinants were then employed to formulate the prognostic nomogram. Subsequently, the bootstrap technique was applied to validate the derived model internally. RESULTS: In total, 224 children with SCI were considered for the final evaluation, having a median monitoring duration of 68.0 months. The predictive nomogram showcased superior differentiation capabilities, yielding a refined C-index of 0.924 (95% CI: 0.883-0.965) for the training cohort and a C-index of 0.863 (95% CI: 0.735-0.933) for the external verification group. Additionally, when applying the aforementioned model to prognostic predictions as classified by the FIM, it demonstrated a high predictive value with a C-index of 0.908 (95% CI: 0.863-0.953). Moreover, the calibration diagrams indicated a consistent match between the projected and genuine ASIA outcomes across both sets. CONCLUSION: The crafted and verified prognostic nomogram emerges as a dependable instrument to foresee the 3-, 5-, and 7-year ASIA and FIM outcomes for children suffering from SCI.

ABSTRACT

Accurate classification and segmentation of polyps are two important tasks in the diagnosis and treatment of colorectal cancers. Existing models perform segmentation and classification separately and do not fully make use of the correlation between the two tasks. Furthermore, polyps exhibit random regions and varying shapes and sizes, and they often share similar boundaries and backgrounds. However, existing models fail to consider these factors and thus are not robust because of their inherent limitations. To address these issues, we developed a multi-task network that performs both segmentation and classification simultaneously and can cope with the aforementioned factors effectively. Our proposed network possesses a dual-branch structure, comprising a transformer branch and a convolutional neural network (CNN) branch. This approach enhances local details within the global representation, improving both local feature awareness and global contextual understanding, thus contributing to the improved preservation of polyp-related information. Additionally, we have designed a feature interaction module (FIM) aimed at bridging the semantic gap between the two branches and facilitating the integration of diverse semantic information from both branches. This integration enables the full capture of global context information and local details related to polyps. To prevent the loss of edge detail information crucial for polyp identification, we have introduced a reverse attention boundary enhancement (RABE) module to gradually enhance edge structures and detailed information within polyp regions. Finally, we conducted extensive experiments on five publicly available datasets to evaluate the performance of our method in both polyp segmentation and classification tasks. The experimental results confirm that our proposed method outperforms other state-of-the-art methods.

ABSTRACT

PURPOSE: Sunken Skin Flap Syndrome (SSFS) is an uncommon, delayed complication after craniectomy characterized by a functional plateau or decline with variable neurologic symptoms, improving after cranioplasty. SSFS negatively impacts the rehabilitation course, with subjective reports of functional improvement after cranioplasty. However, no studies have assessed the impact of cranioplasty on functional recovery rate. This case series aims to analyze SSFS manifestations and management while awaiting cranioplasty. Also, to assess the role of cranioplasty on rehabilitation outcomes and recovery rate in SSFS patients. METHODS: Four patients were identified with SSFS in inpatient rehabilitation. Each patient had unique clinical manifestations, with multiple strategies used for symptomatic control. Patients spent an average of 23 days in rehabilitation with SSFS symptoms before cranioplasty. After cranioplasty, all patients had SSFS symptom resolution. Comparing change in functional independence measure (FIM) scores and FIM efficiency pre-and post-cranioplasty rehabilitation course, a mean improvement of 23 and 0.72 occurred after cranioplasty, respectively. CONCLUSION: A diagnosis of SSFS should be considered in craniectomy patients exhibiting functional decline or plateau with associated neurological symptoms. This study suggests that FIM and FIM efficiency increases in SSFS patients after cranioplasty, supporting prompt cranioplasty to improve functional outcomes and minimize rehabilitation delays.

ABSTRACT

PURPOSE: This study aims to evaluate the ocular surface characteristics in children diagnosed with uveitis and explore the association between uveitis and dry eye disease (DED). METHODS: We included 84 children, 42 with uveitis and 42 healthy children. We performed the OSDI questionnaire and several ocular surface tests, including osmolarity, NITBUT, Schirmer test, and vital staining. We used Fisher's exact test and Mann-Whitney to compare variables and a binomial logistic regression to determine the factors associated with DED. RESULTS: The difference in the prevalence of DED between uveitis (54.8%) and healthy (31%) groups was statistically significant (p < 0.05). Most patients with uveitis had mixed DED, and none of the healthy subjects had a severe form of the disease. There were no statistically significant differences in most of the tear film tests. However, all parameters tended to worsen in the uveitis group, and lipid layer thickness was thinner (p < 0.036). The uveitis group exhibited significantly more symptoms (p < 0.05). In the multivariate logistic regression, uveitis was associated with an odds ratio (OR) of 3.0 (95% CI: 1.07-8.42, p < 0.05) for DED. CONCLUSIONS: Our findings demonstrate a significantly higher prevalence of DED in children with uveitis compared to their healthy counterparts. Furthermore, our analysis indicates that the risk of DED in pediatric patients with uveitis is threefold higher than in healthy children. Therefore, it is crucial for clinicians to vigilantly monitor the development of DED in pediatric patients with uveitis and consider the implementation of preventive treatments.

ABSTRACT

FIM-1 is an acquired metallo-ß-lactamase identified in a multidrug-resistant Pseudomonas aeruginosa (index strain FI-14/157) of clinical origin isolated in 2007 in Florence, Italy. Here we report on a second case of infection by FIM-1-positive P. aeruginosa (FI-17645), which occurred in 2020 in the same hospital. Both FIM-1-positive strains exhibited resistance to all anti-Pseudomonas antibiotics except colistin and cefiderocol. Comparative genomic characterization revealed that the two FIM-positive strains were closely related [core genome difference, 16 single nucleotide polymorphisms (SNPs)], suggesting a local circulation of similar strains. In the FI-14/157 index strain, the blaFIM-1 gene was associated with an ISCR19-like element that likely contributed to its capture downstream an integron platform inserted aboard a Tn21-like transposon, named Tn7703.1, which was associated with a large integrative and conjugative element (ICE) named ICE7705.1, integrated into an att site located within the 3'-end of tRNAGly CCC gene of the P. aeruginosa chromosome. In strain FI-17645, blaFIM-1 was associated with a closely related ICE, named ICE7705.2, integrated in the same chromosomal site. Similar ICE platforms, lacking the blaFIM-1-containing region, were detected in other ST235 P. aeruginosa strains from different geographic areas, suggesting a common ancestry and underscoring the role of these elements in the dissemination of resistance genes in P. aeruginosa. Sequence database mining revealed two draft P. aeruginosa genomes, one from Italy and one from the USA (both isolated in 2012), including a contig with blaFIM-1, suggesting that this resistance gene could have a broader distribution than originally anticipated.

ABSTRACT

O Serviço de Urgência (SU) é direcionado para o doente crítico, com necessidade de estabilização emergente, estando subjacente o cuidado emergente. Mas não são só estes doentes que procuram este serviço, também os doentes em fim de vida com necessidades de cuidados paliativos (CP) entram na porta do SU, sendo necessário que os enfermeiros(as) que lá exercem possam dar uma resposta efetiva neste âmbito. Daí ser fulcral colocar ênfase à investigação de forma a refletir nas estratégias de intervenção mais adequadas a estas pessoas. Objetivo: Analisar as vivências dos enfermeiros no cuidado à pessoa em fim de vida (PFV), no SU. Metodologia: Estudo qualitativo. A recolha de dados foi realizada com recurso a uma entrevista semiestruturada a um grupo focal de sete enfermeiros participantes no estudo, de uma Unidade Local de Saúde (ULS) do Norte de Portugal, durante a primeira semana do mês de abril de 2023. Resultados: Os enfermeiros (as) atribuem o conceito de PFV a uma doença incurável com pouco tempo de vida. Ao conceito de CP associam a promoção de conforto e bem-estar ao doente, a promoção do bem-estar da família, os cuidados promotores de dignidade. Os sentimentos negativos vivenciados pelos enfermeiros expressam sentimentos negativos (frustração) e emoções negativas, como a tristeza, raiva e revolta. As principais intervenções destes enfermeiros dirigidas à PFV enquadram-se no paradigma paliativo como alívio dos sintomas, apoio ao doente e à sua família e proporcionar medidas de conforto. Consideram intervenções fundamentais dirigidas à PFV, o conforto físico e psicológico, dando-se ainda enfâse ao toque. Apontam para a adoção de medidas terapêuticas centradas na abordagem curativa com a formatação e formação recebida e a pressão da família. Foi possível distinguir nas dificuldades a "Sobrecarga de trabalho", "Dificuldades de apoio ao nível da instituição", "Dificuldades ao nível dos recursos". Por sua vez, de entre as necessidades sentidas emergiram a "Necessidade de uma estrutura física adequada", "Necessidade de melhoria ao nível organizacional". Todos foram unânimes em salientar a falta da dignidade para a PFV no SU, por razões físicas/estruturais e por défice de formação. Como estratégias de melhoria, os enfermeiros propõem: o investimento nas equipas multidisciplinares, a melhoria da estrutura física e a uniformização de procedimentos na abordagem da PFV. Conclusão: Os resultados apontam para um leque de dificuldades associadas às vivências dos enfermeiros no cuidado à PFV, contudo também emergem estratégias de melhoria. Devem ser promovidas estratégias organizacionais e individuais. Um exemplo seria a formação/ promoção de atividades de melhoria das estratégias de coping, visando facilitar a gestão dos sentimentos e emoções por parte dos enfermeiros. Das várias medidas propostas destaca-se a criação de uma rede de urgência de CP.


The Emergency Service (ES) is geared towards critically ill patients in need of emergent stabilization, with emergent care as its underlying principle. But it's not only these patients who come to this service. End-of-life patients in need of palliative care (PC) also enter the ES, and nurses working in these services need to provide an effective response in this area. That's why it's crucial to put the emphasis on research in order to reflect on the most appropriate intervention strategies for these people. Objective: To analyze the experiences of nurses in caring for people at the end of life (PEL) in the ES. Methodology: A qualitative study. Data was collected using a semi-structured interview with a focus group of seven nurses participating in the study, from a Local Health Unit in Northern Portugal, during the first week of April 2023. Results: Nurses attribute the concept of PEL to an incurable disease with a short time to live. To the concept of PC they associate the promotion of comfort and well-being for the patient, the promotion of the family's well-being and care that promotes dignity. The negative feelings experienced by the nurses express negative feelings (frustration) and negative emotions, such as sadness, anger, and revolt. These nurses' main interventions aimed at the PEL fall within the palliative paradigm, such as relieving symptoms, supporting the patient and their family and providing comfort measures. They consider physical and psychological comfort to be fundamental interventions aimed at the PEL, with an emphasis on touch. They point to the adoption of therapeutic measures centered on the curative approach with the formatting and training received and pressure from the family. Difficulties included "Work overload", "Difficulties with support from the institution" and "Difficulties with resources". Among the needs felt, the following emerged: "Need for an adequate physical structure", "Need for organizational improvement". All were unanimous in highlighting the lack of dignity for PEL in the ES, due to physical/structural reasons and a lack of training. As strategies for improvement, the nurses propose: investing in multidisciplinary teams, improving the physical structure, and standardizing procedures for dealing with PEL. Conclusion: The results point to a range of difficulties associated with nurses' experiences in caring for people at the end of life, but strategies for improvement also emerge. Organizational and individual strategies should be promoted. One example would be training / promoting activities to improve coping strategies, with the aim of making it easier for nurses to manage their feelings and emotions. Of the various measures proposed, the creation of an emergency PC network stands out.

ABSTRACT

Diffusion MRI (dMRI) allows for non-invasive investigation of brain tissue microstructure. By fitting a model to the dMRI signal, various quantitative measures can be derived from the data, such as fractional anisotropy, neurite density and axonal radii maps. We investigate the Fisher Information Matrix (FIM) and uncertainty propagation as a generally applicable method for quantifying the parameter uncertainties in linear and non-linear diffusion MRI models. In direct comparison with Markov Chain Monte Carlo (MCMC) sampling, the FIM produces similar uncertainty estimates at much lower computational cost. Using acquired and simulated data, we then list several characteristics that influence the parameter variances, including data complexity and signal-to-noise ratio. For practical purposes we investigate a possible use of uncertainty estimates in decreasing intra-group variance in group statistics by uncertainty-weighted group estimates. This has potential use cases for detection and suppression of imaging artifacts.

ABSTRACT

Resumo Entendendo que problemas de saúde sempre são inacabadas, este trabalho examina consequências da declaração do fim de uma emergência de saúde sobre práticas de diferentes redes de cuidado interconectadas. Parte da pesquisa "Etnografando Cuidados...", é um estudo de caso qualitativo de três documentos produzidos depois do anúncio do fim da epidemia da síndrome congênita de Zika vírus. Mostra contextos de produção de narrativas envolvendo redes de pesquisadores, gestores/prestadores de serviço, mães e famílias de acometidos e associações de mães e suas perspectivas diferentes sobre o que é cuidado. Análises de uma apresentação para pesquisadores e de um texto de discussão no IPEA questionam a narrativa técnica da celebração do fim da emergência com base em conhecimento e atendimento, sem tomar em conta a importância dos cuidados relacionais e afetivos e políticos (das redes de mães/familiares e de associações), deixando-os invisibilizados. Descreve o processo da elaboração da moção para o Fórum Zika na Pandemia, elencando e sistematizando propostas de ações através de um diálogo explícito entre integrante das diferentes redes para abordar questões inacabadas pós-emergenciais. Sugere que práticas semelhantes de diálogo entre redes possam promover maior inclusão e sensibilidade a cuidados que contribuem para diminuir sofrimento e defender direitos de pessoas que continuam a conviver cotidianamente com uma síndrome ou doença cujas consequências persistem.


Abstract Understanding health problems as always unfinished, this article examines consequences of the declaration of the end of a health emergency on the practice of different and interconnected care networks. As part of the "Action Ethnography on Care…" research project, this is a qualitative case study of three documents produced after the announcement of the end of the Congenital Zika Virus Syndrome epidemic. It shows the contexts of narrative production involving researchers, managers/ public service workers, mothers and families of the ill, and mothers' associations and their different perspectives about what care is. Analyses of a presentation for researchers and of a working paper for the Applied Economics Research Institute (IPEA) question the technical narrative celebrating the end of the emergency based on knowledge and health service without taking into account the relational, affective and political care (of mothers, families and associations), leaving the latter invisible. It describes the process of elaboration of a motion by the Zika Pandemic Forum, listing and systematizing action proposals produced in an explicit dialogue among participants in different care networks to approach unfinished post-emergency questions. It suggests that similar practices of dialogue between networks can promote greater inclusion and sensitivity to care that contribute to reducing suffering and defending the rights of people who continue to live daily with a syndrome or disease whose consequences persist.

ABSTRACT

Resumo As diretivas antecipadas de vontade são consideradas um componente fundamental do planejamento de cuidados de saúde, recurso comumente empregado por equipes de cuidados paliativos. Dada a importância da rede de cuidado para o paciente com doença incurável e que ameaça sua vida, este estudo tem o objetivo investigar a compreensão que profissionais da saúde, pacientes e cuidadores têm da temática, além de apreender como o tema é conceituado, identificar convergências e divergências nos discursos e discutir como essas noções podem influenciar na qualidade do cuidado. Optou-se pela revisão integrativa da literatura científica, em que foram selecionados e analisados oito artigos. Com isso, priorizou-se dividir a discussão em três tópicos descritivos e analisá-los criticamente. Desse modo, fica evidente a necessidade de continuar a debater essa temática a fim de garantir o desenvolvimento de condutas centradas no paciente, que contemplem suas condições socioeconômicas e seus valores pessoais.


Abstract Advance directives are considered a fundamental component of health care planning, a resource commonly used by palliative care teams. Given the importance of the care network for patients with incurable and life-threatening diseases, this study aims to investigate the understanding that health professionals, patients, and caregivers have of the subject, in addition to understanding how the subject is conceptualized, identifying convergences and divergences in the discourses and how these notions can influence the quality of care. We opted for an integrative review of the scientific literature, in which eight articles were selected and analyzed. Priority was given to dividing the discussion into three descriptive topics and analyzing them critically. Thus, the need to continue debating this topic is evident in order to ensure the development of patient-centered behaviors that take into account their socioeconomic conditions and personal values.


Resumen Las directivas anticipadas se consideran fundamentales en la planificación de la atención de la salud, un recurso comúnmente utilizado por los equipos de cuidados paliativos. Dada la importancia de la red de atención para pacientes con enfermedad incurable y potencialmente mortal, este estudio pretende investigar la comprensión que los profesionales de salud, pacientes y cuidadores tienen sobre el tema, además de comprender cómo se conceptualiza el tema, identificar convergencias y divergencias en los discursos y discutir cómo estas nociones pueden influir en la calidad de la atención. Se realizó una revisión integradora de la literatura científica, en la que se seleccionaron y analizaron ocho artículos. Así, se dio prioridad a dividir la discusión en tres temas descriptivos y analizarlos críticamente. Se evidencia la necesidad de seguir debatiendo este tema para garantizar el desarrollo de comportamientos centrados en el paciente, que incluyan sus condiciones socioeconómicas y valores personales.

ABSTRACT

Resumo Dada a insuficiente evidência científica, decisões relativas à utilização de nutrição e hidratação artificiais em pacientes terminais configuram um importante dilema ético. Identifica-se um conflito entre as perspetivas de "tratar" e "cuidar", com variação quanto a sua utilização conforme o contexto legal e cultural de diferentes países. O intuito deste estudo é esclarecer se essa prática constitui uma medida de cuidado básico ou um tratamento fútil e desproporcionado. Procede-se a uma revisão das diretrizes e dos códigos deontológicos de diferentes países europeus. Em Portugal, na Itália e na Polônia, tal prática é vista como uma medida de cuidado básico; já em países como França, Inglaterra, Noruega, Irlanda, Alemanha, Finlândia, Holanda, Bélgica e Suíça, é considerada um tratamento fútil. Na Romênia, na Croácia e na Hungria, verifica-se um enquadramento ético e legal insuficiente. As diferenças de abordagem a doentes terminais podem ser reflexo das diferentes perspetivas culturais.


Abstract Given the lack of scientific evidence, decisions regarding the administration of artificial nutrition and hydration in terminally ill patients constitute an important ethical dilemma due to the conflict between "treat" and "care" perspectives and the varying usage depending on the legal and cultural background across countries. This study aims to explain whether this practice configures a basic care intervention or a futile medical treatment. Therefore, we review the national guidelines and codes of ethics from several European countries. Countries such as Portugal, Italy, and Poland view it as a basic care intervention, whereas France, England, Norway, Ireland, Germany, Finland, Netherlands, Belgium, and Switzerland, as a medical treatment. Moreover, countries such as Romania, Croatia, and Hungary lack such legal framework. The different approaches regarding the care of terminally ill patients can reflect differences on cultural perspectives.

ABSTRACT

Sarcopenia is widely believed to be linked to poorer outcomes in inpatient rehabilitation. This study aimed to assess the impact of sarcopenia on functional outcomes and dietary intake during hospitalization in adults undergoing convalescent rehabilitation. We conducted a retrospective cohort analysis at a single rehabilitation institution. The Asian Working Group Consensus Criteria for Sarcopenia was used to diagnose. The Functional Independence Measure (FIM) score was used at hospital discharge to measure the primary functional outcome. Energy and protein intakes during hospitalization were calculated as part of the nutritional assessment. There were 126 patients in the research (median age, 73 yr;54% women). Stroke (n = 73;53.4% sarcopenia) and musculoskeletal disorders (n = 53;56.6% sarcopenia) were among the admission diagnoses. Multiple linear regression analysis revealed that the FIM total score at discharge was modestly associated with sarcopenia only in stroke patients (? = 0.1872, P = 0.09), as well as significantly and independently associated with protein intake during admission only in stroke patients (? = 0.3217, P < 0.05). In hospitalized stroke patients undergoing convalescent therapy, sarcopenia is related to lower functional results. Early identification of sarcopenia and treatment with rehabilitation nutrition should be implemented in this population. J. Med. Invest. 70 : 457-463, August, 2023.
