Influence of Hospital Type on Outcomes of Patients With Acute Spontaneous Intracerebral Hemorrhage: A Population-Based Study.

BACKGROUND AND OBJECTIVES: Whether the outcome of patients with spontaneous intracerebral hemorrhage (ICH) differs depending on the type of hospital where they are admitted is uncertain. The objective of this study was to determine influence of hospital type at admission (telestroke center [TSC], primary stroke center [PSC], or comprehensive stroke center [CSC]) on outcome for patients with ICH. We hypothesized that outcomes may be better for patients admitted to a CSC. METHODS: This is a multicenter prospective observational and population-based study of a cohort of consecutively recruited patients with ICH (March 2020-March 2022). We included all patients with spontaneous ICH in Catalonia (Spain) who had a pre-ICH modified Rankin scale (mRS) score of 0-3 and who were admitted to the hospital within 24 hours of onset. We compared patients admitted to a TSC/PSC (n = 641) or a CSC (n = 1,320) and also analyzed the subgroup of patients transferred (n = 331) or not transferred (n = 310) from a TSC/PSC to a CSC. The main outcome was the 3-month mRS score obtained by blinded investigators. Outcomes were compared using adjusted ordinal logistic regression to estimate the common odds ratio (OR) and 95% CI for a shift in mRS scores. A propensity score matching (PSM) analysis was performed for the subgroup of transferred patients. RESULTS: Relevant data were obtained from 1961 of a total of 2,230 patients, with the mean (SD) age of 70 (14.1) years, and 713 (38%) patients were women. After adjusting for confounders (age, NIH Stroke Scale score, intraventricular hemorrhage, hematoma volume, and pre-ICH mRS score), type of hospital of initial admission (CSC vs TSC/PSC) was not associated with outcome (adjusted common OR 1.13, 95% CI 0.93-1.38). A PSM analysis indicated that transfer to a CSC was not associated with more favorable outcomes (OR 0.77, 95% CI 0.55-1.10; p = 0.16). DISCUSSION: In this population-based study, we found that, after adjusting for confounders, hospital types were not associated with functional outcomes. In addition, for patients who were transferred from a TSC/PSC to a CSC, PSM indicated that outcomes were similar to nontransferred patients. Our findings suggest that patient characteristics are more important than hospital characteristics in determining outcome after ICH.

Quality of Life and Related Factors in Patients Undergoing Renal Replacement Therapy at the Hospital General Universitario de Ciudad Real: Cross Sectional Descriptive Observational Study.

Background: The aim of the present study was to determine the relationship between the quality of life of patients on renal replacement therapy and the Symptomatology they presented. Methods: Cross-sectional descriptive observational study: quality of life was assessed by means of the KDQOL-SF questionnaire, Symptomatology by the Palliative Care Outcome Scale-Symptoms Renal questionnaire, and sociodemographic and clinical data of patients in the Hemodialysis Unit (HD) of the Hospital General Universitario de Ciudad Real (HGUCR) by means of personal interviews and clinical history data. Results: A total of 105 patients participated in the study, 63 (60.57%) men and 42 (40.38%) female. The mean age was 62.5 dt (14.84) years. Of these, 43 (41%) were on peritoneal dialysis and 62 (59%) were on hemodialysis. The mean quality of life score was 44.89 dt (9.73). People on hemodialysis treatment presented a better quality of life than those on PD treatment: 49.66 dt (9.73) vs. 38.13 dt (9.12) t = 7.302, p < 0.001. A higher score on the symptom impairment scale (post-renal) correlated with worse scores on the total quality of life score: r = -0.807, p < 0.001. It was observed that those who improved the distress symptom scored better on the total quality of life questionnaire: 50.22 dt (8.44) vs. 46.42 dt (9.05), p < 0.001. Conclusions: The presence and management of the large number of symptoms that appear as side effects, such as distress or depression, could determine changes in some components of quality of life.

Influence of Malignant Pleural Fluid from Lung Adenocarcinoma Patients on Neutrophil Response.

Malignant pleural effusion (MPE) is a common severe complication of advanced lung adenocarcinoma (LAC). Neutrophils, an essential component of tumor infiltrates, contribute to tumor progression and their counts in MPE have been associated with worse outcome in LAC. This study aimed to evaluate phenotypical and functional changes of neutrophils induced by MPE to determine the influence of MPE immunomodulatory factors in neutrophil response and to find a possible association between neutrophil functions and clinical outcomes. Pleural fluid samples were collected from 47 LAC and 25 heart failure (HF) patients. We measured neutrophil degranulation products by ELISA, oxidative burst capacity and apoptosis by flow cytometry, and NETosis by fluorescence. The concentration of degranulation products was higher in MPE-LAC than in PE-HF. Functionally, neutrophils cultured with MPE-LAC had enhanced survival and neutrophil extracellular trap (NET) formation but had reduced oxidative burst capacity. In MPE, NETosis was positively associated with MMP-9, P-selectin, and sPD-L1 and clinically related to a worse outcome. This is the first study associating NETs with a worse outcome in MPE. Neutrophils likely contribute to tumor progression through the release of NETs, suggesting that they are a potential therapeutic target in LAC.

Perception of healthcare providers versus patient reported incidence of chemotherapy-induced nausea and vomiting after the addition of NK-1 receptor antagonists.

PURPOSE: Physicians and nurses often underestimate the incidence of chemotherapy-induced nausea and vomiting (CINV) after both highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). This study assesses physicians' and nurses' perceptions of CINV in their own practices after the introduction of aprepitant. METHODS: A prospective observational study of patients receiving the first cycle of HEC regimens with CDDP and without CDDP or MEC was performed. Eligible patients completed a 6-day diary recording emetic episodes, nausea assessment, and antiemetic medication use. Physicians and nurses estimated the incidence of acute and delayed CINV after the first administration of HEC and MEC. The observed incidence rates of CINV were compared with the rates predicted by healthcare providers. Aprepitant was given to patients receiving HEC regimes with CDDP. RESULTS: Twenty-nine physicians and nurses and 95 patients (87% receiving HEC and 14% MEC) were recruited. The global control of CINV was 66.67% for all patients and 73.33%, 47.06%, and 55.56% for patients receiving HEC regimens with CDDP, HEC regimens without CDDP and MEC, respectively. Physicians and nurses underestimated the control of acute CINV in patients receiving HEC regimens with CDDP, but they accurately predicted the control of delayed CINV. All physicians and nurses predicted the control of acute CINV after HEC regiments without CDDP and after MEC quite accurately, whereas they overestimated the control of delayed CINV after both regimens. CONCLUSIONS: Aprepitant allows for better control of CINV in HEC regimens with CDDP, and this control is accurately perceived by physicians and nurses. However, physicians and nurses overestimate the control of delayed CINV after HEC regimens without CDDP and after MEC. CINV is still an important target for improved therapeutic intervention and the healthcare providers must be aware of its actual incidence.

Experimental supporting data on the influence of platelet-derived factors of malignant pleural effusions on T cell effector functions and their relevance in predicting prognosis of lung adenocarcinoma patients with pleural metastasis.

The data described in this article are supplementary to our primary article "Platelet factor 4 regulates T cell effector functions in malignant pleural effusions". Malignant pleural effusion (MPE) is a common complication of advanced lung adenocarcinoma (LAC) associated with a poor life expectancy [1]. Several challenges need to be addressed to identify non-invasive molecular biomarkers that help to predict the prognosis of LAC patients with MPE [2]. In the primary publication, we proposed that platelet-derived factors, especially platelet factor 4 (PF4), can negatively regulate T lymphocyte activation and granzyme B expression in pleural metastasis and its levels were associated with a worse prognosis. Here, we provide data on the influence of other platelet-derived factors, including transforming growth factor ß (TGF-ß), vascular endothelial factor (VEGF), and P-selectin on T lymphocyte response in MPE and their relevance as prognostic factors in lung cancer patients with pleural metastasis. Pleural fluids from 35 lung adenocarcinoma (LAC) and 20 heart failure (HF) patients were collected by thoracentesis and its platelet-derived factors' content was measured by specific enzyme-linked immunosorbent assay (ELISAs). Correlations between pleural levels of platelet-derived factors and T cell functions were analyzed by Pearson coefficients. Kaplan-Meier curves were used to estimate the effect of pleural concentrations of platelet-derived factors on overall survival of LAC patients with pleural metastasis. These analyses showed that the concentration of platelet-derived factors was not associated with T cell proliferation and cytotoxicity. Furthermore, their levels do not predict the survival of LAC with MPE.

Platelet factor 4 regulates T cell effector functions in malignant pleural effusions.

Malignant pleural effusion (MPE) is defined as the presence of tumor cells in pleural fluid and it is a fatal complication of advanced lung adenocarcinoma (LAC). To understand the immune response to the tumor in MPE, we compared the concentration of immunomodulatory factors in MPE of LAC and pleural effusion of heart failure (HF) patients by ELISA, and the proliferation and cytotoxic phenotype of T cells stimulated in the presence of LAC and HF pleural fluids by cytometry. Platelet factor 4 (PF4), vascular endothelial growth factor (VEGF), transforming growth factor beta (TGF-ß) and P-selectin levels were higher in LAC than in HF pleural fluids. However, plasmatic PF4 and P-selectin levels were similar in LAC and HF. VEGF positively correlated with TGF-ß and sPD-L1 in LAC but not in HF pleural fluids. LAC pleural fluids also inhibited T lymphocyte proliferation and cytotoxicity and reduced IL-17 production. PF4 levels inversely correlated with T cell function. The high content of PF4 in MPE was associated with poor prognosis. Our findings suggest that an impaired response of T lymphocytes induced by PF4 provides a significant advantage for tumor progression.

Migrated T lymphocytes into malignant pleural effusions: an indicator of good prognosis in lung adenocarcinoma patients.

The presence of leukocyte subpopulations in malignant pleural effusions (MPEs) can have a different impact on tumor cell proliferation and vascular leakiness, their analysis can help to understand the metastatic microenvironment. We analyzed the relationship between the leukocyte subpopulation counts per ml of pleural fluid and the tumor cell count, molecular phenotype of lung adenocarcinoma (LAC), time from cancer diagnosis and previous oncologic therapy. We also evaluated the leukocyte composition of MPEs as a biomarker of prognosis. We determined CD4+ T, CD8+ T and CD20+ B cells, monocytes and neutrophils per ml in pleural effusions of 22 LAC and 10 heart failure (HF) patients by flow cytometry. Tumor cells were identified by morphology and CD326 expression. IFNγ, IL-10 and IL-17, and chemokines were determined by ELISAs and migratory response to pleural fluids by transwell assays. MPEs from LAC patients had more CD8+ T lymphocytes and a tendency to more CD4+ T and CD20+ B lymphocytes than HF-related fluids. However, no correlation was found between lymphocytes and tumor cells. In those MPEs which were detected >1 month from LAC diagnosis, there was a negative correlation between pleural tumor cells and CD8+ T lymphocytes. CXCL10 was responsible for the attraction of CD20+ B, CD4+ T and CD8+ T lymphocytes in malignant fluids. Concentrations of IL-17 were higher in MPEs than in HF-related effusions. Survival after MPE diagnosis correlated positively with CD4+ T and CD8+ T lymphocytes, but negatively with neutrophils and IL-17 levels. In conclusion, lymphocyte enrichment in MPEs from LAC patients is mostly due to local migration and increases patient survival.

CURB-65 as an initial prognostic score in Internal Medicine patients.

BACKGROUND: There are few validated tools to assess severity in patients admitted to an Internal Medicine service. The aim of this study was to evaluate if CURB-65 score, previously validated as mortality index in community acquired pneumonia, could also be used in those patients. METHODS: We analyzed prospectively all patients admitted to Hospital Sierrallana (Spain) from 1 March to 31 October 2010. Variables of the CURB-65 score (confusion, serum urea>7mmol/L (42mg/dl), respiratory rate≥30/min, systolic blood pressure<90mmHg and/or diastolic blood pressure≤60mmHg, and age≥65) and other clinical and epidemiological data and laboratory findings were recorded. Charlson comorbidity index was also estimated. Prognostic variables were identified using multiple logistic regression with 30days mortality as the outcome measure. RESULTS: 539 patients were studied (51% males; mean age: 78±14years; mortality 12%). A high CURB-65 score was a significant predictor of 30day mortality (p<0.001). Eighty-six percent of the patients who died had high CURB-65 score at admission, and none of them had low score. Sensitivity and specificity for high CURB-65 score were 86% and 70%, respectively, and negative predictive value was 97%. Receiver-operator characteristic curve showed an area under curve of 0.79 for CURB 65-score. Charlson index also correlated with mortality, but its performance was worse than that of CURB-65. CONCLUSION: Our findings suggest that CURB-65 score may be a simple and useful tool to help clinicians in establishing the prognosis of patients admitted to general Internal Medicine wards.
