Background and Aim. Hematological disorders (HD) affect millions of people annually worldwide. Nutritional care is essential in acute or chronic HD, especially in controlling metabolic and ...gastrointestinal disorders that affect the nutritional status of individuals. Methods. A bibliographic survey was carried out between 2020 and 2022 using two databases: PubMed/MEDLINE and Scientific Electronic Library Online (SciELO) and the information source Academic Google, irrespective of language or geography. Results. In the first nutrition consultation (FNC), there should be an investigative direction focused on nutritional interventions in the short, medium, and long term. The record in the patient’s medical record is relevant for carrying out the consultation, according to the recommendations of the normative councils of medicine and nutrition. The main steps to be followed are the investigation of the presence of food allergies and intolerances; the drugs/nutritional supplements in use; changes in the digestive tract; the presence or absence of picamalacia; and socioeconomic and lifestyle data. In addition, it is necessary to carry out laboratory evaluations, semiological assessment, anthropometric assessment, and assessment of food consumption. In the end, the nutritional approach should be composed of calculation of energy and macronutrient and micronutrient needs, intervention in nutritional status deviations, nutritional guidelines, and nutritional therapeutic planning of return, focusing on adherence to treatment. Conclusion. The first nutrition consultation may represent investigative steps that help the clinical nutritionist in the management, allowing a longitudinal and specific nutritional therapeutic planning for patients assisted in large reference centers for hematological disease.
Abstract
Introduction: In December 2019, a new type of coronavirus was discovered in Wuhan, China, characterized by a picture of atypical pneumonia composed of fever, dry cough and progressive ...dyspnea. Autopsy analyzes of patients with Covid-19 were performed, and hyperactivation of cytotoxic T cells was observed, suggesting an increase in humoral-type immunological signaling, where interleukin 6 (IL-6) is a mediator present that can fit as a potential critical agent for exacerbation of inflammatory conditions. In addition, not only interleukin-6, but also serum C-reactive protein (CRP) and ferritin have been recognized as strong predictors of COVID-19 severity. Recent studies have shown that the use of liraglutide has antioxidant and anti-inflammatory effects in vitro. Thus, the present case report discusses the possible anti-inflammatory properties of the antidiabetic drug liraglutide (Saxenda), in Covid-19. Clinical Case: JCMS, 45 years, male, married, obese grade 2 (BMI: 38.2), sought medical service on August 18, 2020, bringing a positive result of the RT-PCR test for Covid-19, performed in last day. The patient was in good general condition, reporting mild headache and adynamia. He was prescribed to start a treatment with Saxenda (6mg/ml - started 0.6mg/day at week 1, with a gradual increase up to 3mg/day at week 5); Jardiance (25mg / day); Fluimicil (600mg); Ivermectin (6mg) and Colchicine (0.5mg every 12 hours). In addition, collection of laboratory tests was requested. Examination results: IL6: <1.5 pg/mL; Ferritin: 819 ng/ml; C-reactive protein: 5.1mg/L. On August 24, the patient was tachycardic (HR 120–140 bpm) associated with headache and fever (38 °C). Azithromycin (500mg), dexamethasone (4mg) and dipyrone (1g) were prescribed. Collection of laboratory tests was requested. Examination results: IL6: 9.3 pg/mL; Ferritin: 1085 ng/ml; C-reactive protein:23.9mg/L. On September 3, the patient was in good general condition, eupneic, afebrile, with no complaints to declare. On September 6, the collection of laboratory tests was requested. Examination results: IL6: <1.5 pg/mL; Ferritin: 687 ng/ml; C-reactive protein: 1.7mg/L. Conclusion: Based on the described report, it is possible to observe a good clinical and laboratory evolution of the patient with Covid-19 who, among the drugs used, made use of liraglutida. Diabetes and obesity are considered significant risk factors for morbidity and mortality by COVID-19, since they are a condition of low-grade chronic inflammation and in these conditions, inflammatory markers such as CRP, IL-6 and ferritin have strong signs of alteration. Thus, the possible beneficial effect of the administration of liraglutide in obese patients is highlighted, as a potential anti-inflammatory effect, especially in the COVID-19 era.
Essential thrombocythemia is the category of myeloproliferative syndromes, generally characterized by a group of clonal stem cell diseases that present a disturbance in the growth of one or more sets ...of hematopoietic cells. All long clinical treatment, patients may experience gastrointestinal disorders and other metabolic processes that can lead to weight loss and malnutrition. Cytokine is involved in the control of appetite, digestive, and metabolic processes in the body, it can be assumed that increased stimulation could impair the control of these processes leading to loss of body mass. Effective and systematic nutritional intervention is required to ensure patient compliance with treatment and improved nutritional status.
The human parasitic disease Schistosomiasis is caused by the
trematode flatworm that infects freshwaters in tropical regions of the world, particularly in Sub-Saharan Africa, South America, and the ...Far-East. It has also been observed as an emerging disease in Europe, due to increased immigration. In addition to improved therapeutic strategies, it is imperative to develop novel, rapid, and sensitive diagnostic tests that can detect the
parasite, allowing timely treatment. Present diagnosis is difficult and involves microscopy-based detection of Schistosoma eggs in the feces. In this context, we present the 3.22 Å resolution crystal structure of the circulating antigen Serine protease inhibitor from
(SmSPI), and we describe it as a potential serodiagnostic marker. Moreover, we identify three potential immunoreactive epitopes using in silico-based epitope mapping methods. Here, we confirm effective immune sera reactivity of the recombinant antigen, suggesting the further investigation of the protein and/or its predicted epitopes as serodiagnostic Schistosomiasis biomarkers.
Chagas disease (CD) is a vector-borne parasitosis, caused by the protozoan parasite
, that affects millions of people worldwide. Although endemic in South America, CD is emerging throughout the world ...due to climate change and increased immigratory flux of infected people to non-endemic regions. Containing of the diffusion of CD is challenged by the asymptomatic nature of the disease in early infection stages and by the lack of a rapid and effective diagnostic test. With the aim of designing new serodiagnostic molecules to be implemented in a microarray-based diagnostic set-up for early screening of CD, herein, we report the recombinant production of the extracellular domain of a surface membrane antigen from
(
SMP) and confirm its ability to detect plasma antibodies from infected patients. Moreover, we describe its high-resolution (1.62 Å) crystal structure, to which in silico epitope predictions were applied in order to locate the most immunoreactive regions of
SMP in order to guide the design of epitopes that may be used as an alternative to the full-length antigen for CD diagnosis. Two putative, linear epitopes, belonging to the same immunogenic region, were synthesized as free peptides, and their immunological properties were tested in vitro. Although both peptides were shown to adopt a structural conformation that allowed their recognition by polyclonal antibodies raised against the recombinant protein, they were not serodiagnostic for
infections. Nevertheless, they represent good starting points for further iterative structure-based (re)design cycles.
Objetivo: avaliar a incidência de lesão por pressão na posição prona e seus fatores de risco em pacientes admitidos em unidades de terapia intensiva diagnosticados com COVID-19. Métodos: trata-se de ...um estudo de coorte prospectiva (n=30) com duração de seis meses. Informações relacionadas a estado da prona, tempo de duração, presença ou ausência de lesão por pressão e características sociodemográficas e clínicas foram coletadas. Estatística descritiva e inferencial foi realizada para comparar os pacientes que desenvolveram e os que não desenvolveram lesão por pressão. Para análise dos dados, foi utilizada Regressão de Poisson com variância robusta. Resultados: o tempo médio na posição prona foi de 20,1 horas (DP=3,9). A incidência de lesão por pressão foi de 70%, sendo as localizações mais comuns: tórax esquerdo, abdômen, bochechas e testa. Ao comparar os grupos com e sem lesão por pressão, não houve diferença entre eles (p>0,05). Conclusão: a incidência não foi associada a nenhuma variável sociodemográfica ou clínica dos pacientes.
