Evaluation of sarcopenia and phase angle in elderly patients with Parkinson's Disease.

PURPOSE: To investigate sarcopenia and related factors and to determine the disease-specific phase angle (PhA) cut-off score in detecting sarcopenia in elderly patients with Parkinson's Disease (PD). METHODS: This cross-sectional study was conducted with 89 participants. The Mini-Nutritional Assessment (MNA), the Eating Attitude Test-10 (EAT-10), the Physical Activity Scale for The Elderly (PASE) questionnaire and the Hoehn-Yahr scale have been used. Additionally, anthropometric measurements were performed. The diagnosis of sarcopenia was based on the new consensus published by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). PhA has been performed by Bioelectrical Impedance Analysis (BIA) with Tanita MC 780®. RESULTS: The mean age was of the participants 68.9 ± 6.4 years, and 57.3% were male. The prevalence of sarcopenia was 12.3%. PhA, malnutrition, age, disease severity, low calf circumference (CC), low body mass index (BMI), the difference between the pre-diagnosis and current weight loss, dopaminergic treatment, and low PASE score were associated with sarcopenia. The cut-off value of the PhA in terms of the ability to identify sarcopenia was <4.5o with a sensitivity of 53.3% and a specificity of 93.2% (p = 0.001). When we grouped the PhA of the patients according to this cut-off score, it was seen that 14.6% of them were sarcopenic. Age, disease severity, PASE score and hand grip strength were significantly related to both sarcopenia and PhA. CONCLUSION: It is important to be aware of sarcopenia and related factors at an early stage in Parkinson's patients. Because of disease-related symptoms, it may be more appropriate to use a disease-specific PhA cut-off score in the definition of sarcopenia.

Association between vitamin D receptor gene FokI polymorphism and mortality in patients with sepsis.

BACKGROUND: Sepsis is life-threatening organ dysfunction as a result of the host's dysregulated immune response to infection. The vitamin D receptor (VDR) gene FokI polymorphism influences immune cell behavior. In the present study, we aimed to investigate the association between VDR FokI polymorphism and mortality in sepsis and non-sepsis patients in the intensive care unit (ICU). METHODS AND RESULTS: This is a prospective observational study involving 96 sepsis and 96 non-sepsis patients admitted to the Ege University ICU. VDR FokI polymorphisms were investigated, as well as the relationship between the identified polymorphisms and mortality.  In-hospital mortality was 27.1% in the sepsis group and 8.33% in the non-sepsis group (p = 0.001). The frequencies of VDR FokI TT, TC, and CC genotypes were 8 (8.33%), 48 (50.0%), and 40 (41.7%) in the sepsis group, and 11 (11.5%), 42 (43.8%), and 43 (44.8%) in the non-sepsis group, respectively (p = 0.612). In the sepsis group, the frequencies of Fokl TT, TC, and CC genotypes did not differ significantly between survivors and non-survivors. However, homozygous C allele carriers had lower overall mortality (p = 0.047). CONCLUSION: The VDR FokI polymorphism, particularly the CC genotype, appears to be associated with lower mortality in ICU patients.

Lactate level is an independent predictor of mortality in patients with hematologic malignancy receiving urgent chemotherapy in intensive care unit.

BACKGROUND: Intensive care unit (ICU) survival of cancer patients has improved. Urgent chemotherapy has become feasible in critically ill patients with specific organ dysfunction due to hematological malignancies. OBJECTIVE: The aim of the study was to assess ICU mortality rates and the factors associated with mortality in patients with hematologic malignancies receiving urgent chemotherapy in the ICU. METHODS: We retrospectively included all patients admitted to the ICU who received chemotherapy due to hematologic malignancy in 2012-2022. RESULTS: Of the 129 patients undergoing chemotherapy in the ICU, 50 (38.7 %) died during the ICU follow-up. The following conditions were significantly more common among nonsurvivors: presence of infection at the time of ICU admission (p < 0.001), the requirement for mechanical ventilation during ICU stay (p < 0.001), the need for noninvasive mechanical ventilation during ICU stay (p = 0.014), vasopressor support (p < 0.001), and sepsis (p < 0.001). Logistic regression analysis revealed that among laboratory parameters on ICU admission, lactate (p = 0.008), albumin (p = 0.022), C-reactive protein (p = 0.046), baseline sequential organ failure assessment (SOFA) score (p < 0.001), newly developed heart failure (p = 0.006), and the requirement for vasopressor agents during ICU stay (p < 0.001) significantly influenced the risk of mortality in the univariate analysis. The multivariate analysis revealed lactate levels (p = 0.047) on ICU admission as an independent predictor of mortality. CONCLUSION: The development of heart failure and lactate levels on admission were the main predictors of mortality. Additionally, higher SOFA scores revealed that illness severity was closely associated with mortality. Future studies should focus on strategies to further reduce these risks and achieve the best outcomes for these patients.

Impact of the empirical therapy timing on the clinical progress of septic shock patients.

AIM: To evaluate the effect of timing of antimicrobial therapy on clinical progress of patients with septic shock. MATERIALS AND METHOD: We included 204 adult patients diagnosed with septic shock according to Sepsis-3 criteria between March 2016 and April 2021. One-month survival was evaluated using univariate and logistic regression analysis. RESULTS: Antibiotic treatment was initiated within 1 h of the vasopressors in 26.4 % of patients. One-month mortality did not differ significantly between patients with and without empirical therapy coverage on etiological agents. Univariate factors that significantly affected one-month survival were starting antibiotics at the first hour, the unit where the case was diagnosed with septic shock, SOFA scores, qSOFA scores, and lactate level. In multivariate analysis, diagnosis of septic shock in the Emergency Service, SOFA score ≥11, qSOFA score of three and lactate level ≥4 were significantly associated with one-month mortality. CONCLUSION: Training programs should be designed to increase the awareness of septic shock diagnosis and treatment in the Emergency Service and other hospital units. Additionally, electronic patient files should have warning systems for earlier diagnosis and consultation.

Interação Letal entre Síndrome Hemofagocítica e Insuficiência Cardíaca Recentemente Desenvolvida / Mortal Interaction Between Hemophagocytic Syndrome and Newly Developed Heart Failure

Resumo Fundamento: A síndrome hemofagocítica (SHF) é uma síndrome hiperinflamatória debilitante. O status da insuficiência cardíaca (IC) com fração de ejeção preservada (ICFEP) está intimamente relacionado ao aumento da inflamação sistêmica e intramiocárdica. Objetivos: este estudo pretende determinar os preditores de mortalidade e os parâmetros de monitoramento confiáveis nos casos de SHF que desenvolveram a ICFEP durante seu curso clínico. Métodos: Trinta e nove pacientes, diagnosticados com SHF de acordo com os critérios diagnósticos do estudo HLH 2004 com Hscore ≥169, e com aspiração ou biópsia de medula óssea comprovada, foram recrutados retrospectivamente. Foram investigados retrospectivamente os fatores de risco tradicionais, como proteína C reativa sérica, níveis de albumina e ferritina com contagens de linfócitos e plaquetas, e fatores não tradicionais, como relação neutrófilolinfócito (NLR), relação linfócito-monócito (MLR), volume plaquetário médio (MPV) e pró-peptídeo natriurético cerebral N-terminal (NTproBNP). Analisou-se a relação entre os valores laboratoriais alterados ao longo do tempo entre si e com a mortalidade. O nível de significância geral foi de 5%. Resultados: Foi demonstrado que a alteração temporal dos níveis de índice cardiotorácico (ICT), NTproBNP sérico, ferritina, PCR e albumina foram detectados como sendo preditores de mortalidade (p<0,05, para todos) em análise univariada. As contagens de linfócitos e plaquetas com valores de NLR e MPV também foram significativos (p<0,05). A relação entre NT-proBNP e o aumento dos marcadores inflamatórios sistêmicos também foi considerada significativa. Além de fatores de risco tradicionais, os níveis de ferritina sérica, e os níveis de NLR, MLR e MPV foram considerados significativamente correlacionados entre si. Conclusão: Acompanhado de parâmetros de monitoramento confiáveis, o diagnóstico rápido e o tratamento antiinflamatório agressivo com controle rígido de volume podem salvar vidas de pacientes com SHF que sofrem de complicações por ICFEP. O monitoramento rígido da inflamação pode prever o resultado do paciente que sofre de ICFEP.

Abstract Background: Hemophagocytic syndrome (HPS) ia s devastating hyperinflammatory syndrome. Heart failure (HF) with preserved ejection fraction (HFpEF) status is closely correlated with increased inflammation, both systemic and intramyocardial. Objectives: This study sought to determine mortality predictors and reliable follow-up parameters in HPS that developed HFpEF during the clinical course. Method: Thirty-nine patients, diagnosed as HPS, according to HLH 2004 diagnostic criteria, with an HScore of ≥169 and proven bone marrow aspiration or biopsy, were recruited retrospectively. Both traditional, serum C-reactive protein, albumin and ferritin levels with lymphocyte, and platelet counts, as well as non-traditional risk factors, neutrophil-to-lymphocyte count (NLR), monocyte-to-lymphocyte count (MLR), mean platelet volume (MPV), and N-Terminal pro-brain natriuretic peptide (NTproBNP), were investigated retrospectively. The relationship between time-changed laboratory values both among themselves and with mortality. The overall significance level was set at 5%. Results: This study showed that temporal change of cardiothoracic ratio (CTR), serum NTproBNP, ferritin, CRP, and albumin levels were detected as mortality predictors (p<0.05, for all) in the univariate analysis. Lymphocyte and platelet counts with NLR and MPV values were also significant (p<0.05). The relationship between NT-proBNP and increased systemic inflammatory markers proved to be significant. In addition to traditional risk factors, serum ferritin levels, NLR, MLR, and MPV levels also proved to be significantly correlated with each other. Conclusion: Accompanied by reliable follow-up parameters, rapid diagnosis and aggressive anti-inflammatory treatment with tight volume control can be life-saving in HPS patients who suffer from HFpEF. Close monitoring of inflammation may predict the outcome of patients suffering from HFpEF.
