Identifying patients with prostate cancer at increased risk for haematuria during anticoagulation for venous thromboembolism.

BACKGROUND: Haematuria is a common complication in prostate cancer patients receiving anticoagulation for venous thromboembolism (VTE). Early identification of at-risk patients might help to reduce its incidence and severity. METHODS: We used data from the RIETE registry to develop a prognostic score for haematuria during the first year of anticoagulation for VTE. The prognostic score was built using regression coefficients. RESULTS: From March 2001 through March 2021, 1934 patients with prostate cancer and acute VTE were enrolled. Of these, 1034 (53 %) initially presented as pulmonary embolism and 900 (47 %) as isolated deep vein thrombosis (DVT). During anticoagulation (median 181 days; inter-quartile range: 97-354), 99 patients (5.1 %) developed haematuria (fatal 1, major 27, non-major 72). The incidence rate was: 8 events per 100 patient-years (95%CI 6.5-9.7). Median time to haematuria was 53 days (IQR 4-134). On multivariable analysis, recent haematuria, initial presentation as DVT, comorbidity, metastases, haemoglobin levels <11 g/dL, creatinine >1.2 mg/dL, and radiotherapy independently predicted the risk for haematuria. C-statistics was 0.71 (95%CI: 0.65-0.77). A cut-off of ≥1.5 points classified 312 patients (20 %) at high-risk and had the highest sensitivity (51 %; 95%CI: 39-62) and specificity (82 %; 95%CI: 79-83). Our score improved the performance and non-event net reclassification index (NRI) of the RIETE score (c-statistics: 0.61; 95%CI: 0.54-0.68; NRI: 0.09) or VTE-BLEED score (c-statistics: 0.64; 95%CI: 0.58-0.71; NRI: 0.76). CONCLUSIONS: A prognostic score for haematuria during anticoagulation for VTE performed well in patients with prostate cancer, and improved identification compared to other validated scores.

Survival Outcomes in Palliative Sedation Based on Referring Versus On-Call Physician Prescription.

This study sought to determine the survival duration of patients who underwent palliative sedation, comparing those who received prescriptions from referring physicians versus on-call physicians. It included all patients over 18 years old who died in the Palliative Care, Internal Medicine, and Oncology units at the Hospital Universitario of Jerez de la Frontera between 1 January 2019, and 31 December 2019. Various factors were analyzed, including age, gender, oncological or non-oncological disease, type of primary tumor and refractory symptoms. Statistical analysis was employed to compare survival times between patients who received palliative sedation from referring physicians and those prescribed by on-call physicians, while accounting for other potential confounding variables. This study revealed that the median survival time after the initiation of palliative sedation was 25 h, with an interquartile range of 8 to 48 h. Notably, if the sedation was prescribed by referring physicians, the median survival time was 30 h, while it decreased to 17 h when prescribed by on-call physicians (RR 0.357; 95% CI 0.146-0.873; p = 0.024). Furthermore, dyspnea as a refractory symptom was associated with a shorter survival time (RR 0.307; 95% CI 0.095-0.985; p = 0.047). The findings suggest that the on-call physician often administered palliative sedation to rapidly deteriorating patients, particularly those experiencing dyspnea, which likely contributed to the shorter survival time following sedation initiation. This study underscores the importance of careful patient selection and prompt initiation of palliative sedation to alleviate suffering.

Sex-Related Differences in Patient Characteristics, Risk Factors, and Symptomatology in Older Adults with Pulmonary Embolism: Findings from the SERIOUS-PE Study.

Sex-specific factors are implicated in pulmonary embolism (PE) presentation in young patients, as indicated by increased risk in pregnancy. Whether sex differences exist in PE presentation, comorbidities, and symptomatology in older adults, the age group in which most PEs occur, remains unknown. We identified older adults (aged ≥65 years) with PE in a large international PE registry replete with information about relevant clinical characteristics (RIETE registry, 2001-2021). To provide national data from the United States, we assessed sex differences in clinical characteristics and risk factors of Medicare beneficiaries with PE (2001-2019). The majority of older adults with PE in RIETE (19,294/33,462, 57.7%) and in the Medicare database (551,492/948,823, 58.7%) were women. Compared with men, women with PE less frequently had atherosclerotic diseases, lung disease, cancer, or unprovoked PE, but more frequently had varicose veins, depression, prolonged immobility, or history of hormonal therapy (p < 0.001 for all). Women less often presented with chest pain (37.3 vs. 40.6%) or hemoptysis (2.4 vs. 5.6%) but more often with dyspnea (84.6 vs. 80.9%) (p < 0.001 for all). Measures of clot burden, PE risk stratification, and use of imaging modalities were comparable between women and men. PE is more common in elderly women than in men. Cancer and cardiovascular disease are more common in men, whereas transient provoking factors including trauma, immobility, or hormone therapy are more common in elderly women with PE. Whether such differences correlate with disparities in treatment or differences in short- or long-term clinical outcomes warrants further investigation.

Prognostic Impact of Active Cigarette Smoking on Mortality in Patients with Acute Venous Thromboembolic Events, Findings from Real World Data.

Background and Objectives: The influence of smoking habits on mortality, VTE recurrence, and major bleeding in patients receiving anticoagulant therapy for venous thromboembolism (VTE) has not been consistently evaluated. Materials and Methods: We used data from the RIETE (Registro Enfermedad TromboEmbólica) registry to compare mortality, VTE recurrence, and major bleeding risk in smoking versus non-smoking patients with acute VTE. Results: 50,881 patients (43,426 non-smoking and 7455 smoking patients) were included. After a median follow-up of 8.8 months, 7110 patients died (fatal PE 292 and fatal bleeding 281), 3243 presented VTE recurrence, and 1579 had major bleeding. At multivariate analysis, smoking behavior was associated with a higher hazard of death, (HR: 1.28; 95% CI: 1.19-1.40). The risk of VTE recurrence was marginally increased in smoking patients compared to non-smoking patients (1.14; 95% CI: 1.02-1.27). Major bleeding did not differ in smoking and non-smoking patients (1.15; 95% CI: 0.96-1.38). The presence of cancer did not appear to influence the association between smoking habits and death (HR: 1.34; 95% CI: 1.22-1.47 in cancer patients and HR: 1.23; 95% CI: 1.04, 1.45 in non-cancer patients, respectively) Conclusions: the risk of death after an acute episode of VTE appeared to be higher in smoking than in non-smoking patients and this risk is higher between patients presenting PE at the onset of symptoms.

Case-Control Analysis of the Impact of Anemia on Quality of Life in Patients with Cancer: A Qca Study Analysis.

Anemia is a common condition in cancer patients and is associated with a wide variety of symptoms that impair quality of life (QoL). However, exactly how anemia affects QoL in cancer patients is unclear because of the inconsistencies in its definition in previous reports. We aimed to examine the clinical impact of anemia on the QoL of cancer patients using specific questionnaires. We performed a post-hoc analysis of a multicenter, prospective, case-control study. We included patients with cancer with (cases) or without (controls) anemia. Participants completed the European Organization for Research and Treatment of Cancer Quality of Life questionnaire version 3.0 (EORTC QLQ-C30) and Euro QoL 5-dimension 3-level (EQ-5D-3L) questionnaire. Statistically significant and clinically relevant differences in the global health status were examined. From 2015 to 2018, 365 patients were included (90 cases and 275 controls). We found minimally important differences in global health status according to the EORTC QLQ-C30 questionnaire (case vs. controls: 45.6 vs. 58%, respectively; mean difference: -12.4, p < 0.001). Regarding symptoms, cancer patients with anemia had more pronounced symptoms in six out of nine scales in comparison with those without anemia. In conclusion, cancer patients with anemia had a worse QoL both clinically and statistically.

Psychotropic Drugs and Outcome in Patients Receiving Anticoagulant Therapy for Venous Thromboembolism.

BACKGROUND: The influence (if any) of the use of psychotropic drugs on outcome in patients receiving anticoagulant therapy for venous thromboembolism (VTE) has not been consistently evaluated. METHODS: We used data from the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the risk for VTE recurrences, major bleeding, or death during the course of anticoagulant therapy, according to the use of psychotropics at baseline. RESULTS: Among 49,007 patients with VTE enrolled from February 2009 to September 2019, total 5,230 (11%) were using psychotropics at baseline: antidepressants 3,273 (6.7%), antipsychotics 1,588 (3.2%), and anticholinesterases 369 (0.7%). During the course of anticoagulation, 1,259 patients developed VTE recurrences, 1,231 bled, and 3,988 died (fatal pulmonary embolism 269 and fatal bleeding 187). On multivariable analysis, patients using psychotropics at baseline had a similar risk for VTE recurrences (adjusted hazard ratio [HR]: 0.81; 95% confidence interval [CI]: 0.58-1.12), a nonsignificantly higher risk for major bleeding (adjusted HR: 1.15; 95% CI: 0.97-1.35), and a higher risk for intracranial bleeding (adjusted HR: 1.83; 95% CI: 1.32-2.53) or death (adjusted HR: 1.44; 95% CI: 1.32-1.57) compared with those not using psychotropics. When separately analyzed, the highest risk for intracranial bleeding was found in patients using antidepressants (adjusted HR: 1.60; 95% CI: 1.08-2.37) or antipsychotics (adjusted HR: 2.02; 95% CI: 1.17-3.49) but not in those on anticholinesterases (adjusted HR: 1.69; 95% CI: 0.62-4.60). CONCLUSION: During the course anticoagulation for VTE, patients using psychotropics at baseline were at increased risk for intracranial bleeding.

Effect of dapagliflozin on arterial stiffness in patients with type 2 diabetes mellitus. / Efecto de dapagliflozina sobre la rigidez arterial en pacientes con diabetes mellitus tipo 2.

INTRODUCTION: Oral antidiabetic inhibitors of the sodium-glucose cotransporter (SGLT2i) reduce cardiovascular morbidity and mortality in DM2. The increase in arterial stiffness can participate in this morbidity and mortality. The aim of this study was to analyse the effect of the administration of dapagliflozin on arterial stiffness. PATIENTS AND METHODS: Prospective observational study that included 32 patients with DM2. Before starting dapagliflozin, and at 6 and 12 months, biochemical parameters in blood and urine were analysed. Before starting dapagliflozin and at 12 months the velocity of the carotid-femoral pulse (VPc-f) was determined by tonometry. Changes in the variables and their interrelation was analysed by repeated data ANOVA, Wilcoxon's test and multiple regression. RESULTS: A significant decrease in the VPc-f was observed. There was no association between decreased VPc-f and changes in blood glucose, uric acid, blood pressure or weight. CONCLUSIONS: Dapagliflozin, in subjects with DM2, produces a medium to long-term decrease in arterial stiffness.

The diagnostic value of pleural fluid homocysteine in malignant pleural effusion.

BACKGROUND: Pleural fluid homocysteine (HCY) can be useful for diagnosis of malignant pleural effusion (MPE). There are no published studies comparing the diagnostic accuracy of HCY with other tumour markers in pleural fluid for diagnosis of MPE. The aim was to compare the accuracy of HCY with that of carcinoembryonic antigen (CEA), cancer antigen (CA) 15.3, CA19.9 and CA125 in pleural fluid and to develop a probabilistic model using these biomarkers to differentiate benign (BPE) from MPE. METHODS: Patients with pleural effusion were randomly included. HCY, CEA, CA15.3, CEA19.9 and CA125 were quantified in pleural fluid. Patients were classified into two groups: MPE or BPE. By applying logistic regression analysis, a multivariate probabilistic model was developed using pleural fluid biomarkers. The diagnostic accuracy was determined by receiver operating characteristic (ROC) curves and calculating the area under the curve (AUC). RESULTS: Population of study comprised 133 patients (72 males and 61 females) aged between 1 and 96 years (median = 70 years), 81 BPE and 52 MPE. The logistic regression analysis included HCY (p<0.0001) and CEA (p = 0.0022) in the probabilistic model and excluded the other tumour markers. The probabilistic model was: HCY+CEA = Probability(%) = 100×(1+e-z)-1, where Z = 0.5471×[HCY]+0.3846×[CEA]-8.2671. The AUCs were 0.606, 0.703, 0.778, 0.800, 0.846 and 0.948 for CA125, CA19.9, CEA, CA15.3, HCY and HCY+CEA, respectively. CONCLUSIONS: Pleural fluid HCY has higher accuracy for diagnosis of MPE than CEA, CA15.3, CA19.9 and CA125. The combination of HCY and CEA concentrations in pleural fluid significantly improves the diagnostic accuracy of the test.

A Case-Control Analysis of the Impact of Venous Thromboembolic Disease on Quality of Life of Patients with Cancer: Quality of Life in Cancer (Qca) Study.

Although there is published research on the impact of venous thromboembolism (VTE) on quality of life (QoL), this issue has not been thoroughly investigated in patients with cancer-particularly using specific questionnaires. We aimed to examine the impact of acute symptomatic VTE on QoL of patients with malignancies. This was a multicenter, prospective, case-control study conducted in patients with cancer either with (cases) or without (controls) acute symptomatic VTE. Participants completed the EORTC QLQ-C30, EQ-5D-3L, PEmb-QoL, and VEINES-QOL/Sym questionnaires. Statistically significant and clinically relevant differences in terms of global health status were examined. Between 2015 and 2018, we enrolled 425 patients (128 cases and 297 controls; mean age: 60.2 ± 18.4 years). The most common malignancies were gastrointestinal (23.5%) and lung (19.8%) tumors. We found minimally important differences in global health status on the EQ-5D-3L (cases versus controls: 0.55 versus 0.77; mean difference: -0.22) and EORTC QLQ-C30 (47.7 versus 58.4; mean difference: -10.3) questionnaires. There were minimally important differences on the PEmb-QoL questionnaire (44.4 versus 23; mean difference: -21.4) and a significantly worse QoL on the VEINES-QOL/Sym questionnaire (42.7 versus 51.7; mean difference: -9). In conclusion, we showed that acute symptomatic VTE adversely affects the QoL of patients with malignancies.

Clinical outcome in patients with venous thromboembolism receiving concomitant anticoagulant and antiplatelet therapy.

INTRODUCTION: Patients with arterial disease receiving antiplatelet agents may develop venous thromboembolism (VTE) and need anticoagulant therapy, although concomitant use of these drugs may increase bleeding risk. We analyzed RIETE data and compared clinical outcomes depending on decision to discontinue or maintain antiplatelet therapy at VTE diagnosis. METHODS: Consecutive patients with acute VTE were enrolled in RIETE. Only patients receiving antiplatelet therapy at baseline were included in this analysis. Primary outcomes were: rate of subsequent ischemic events, major bleeding or death during anticoagulation course. RESULTS: 1178 patients who received antiplatelet drugs at VTE diagnosis were included. Antiplatelet therapy was discontinued in 62% of patients. During anticoagulation course, patients also receiving antiplatelet therapy had higher rates of lower limb amputations (2.28 vs. 0.21 events per 100 patients-years; p<0.01), any ischemic events (5.7 vs. 2.28 events per 100 patients-years; p<0.05) or death (23.6 vs. 13.9 deaths per 100 patients-years; p<0.01). No differences in the rate of major bleeding or recurrent VTE were revealed. In matched analysis, patients on antiplatelet therapy were found to have a significantly higher rate of limb amputations (odds ratio: 15.3; 95% CI: 1.02-229) and an increased number of composite outcomes including all-cause deaths, arterial and VTE events (odds ratio: 1.46; CI: 1.03-2.06), with no differences in major bleeding rate. CONCLUSION: Concomitant anticoagulant and antiplatelet therapy in patients with VTE and arterial disease is not associated with increased risk for bleeding, recurrent VTE or death. The worse outcome observed in patients who continued antiplatelet therapy requires further investigations.

Concurrent overexpression of serum p53 mutation related with Helicobacter pylori infection.

BACKGROUND & AIMS: In the province of Cadiz (Spain), the adjusted mortality rate for gastric cancer in the coastal town of Barbate is 10/100.000 inhabitants, whereas in the inland town of Ubrique, the rate is twice as high. The rate of Helicobacter pylori (H. pylori) infection (H. pylori antibodies) in the normal population was 54% in Ubrique, but only 32% in Barbate. In the two decades since its original discovery, p53 has found a singularly prominent place in our understanding of human gastric cancer and H. pylori cause accumulation of reactive oxygen species in the mucosa compartment. This study was designed to compare serum levels of p53 in a population characterized by high mortality due to stomach cancer and a high prevalence of H. pylori infection and another population in which mortality from this cause and the prevalence of H. pylori infection are low. MATERIALS AND METHODS: 319 subjects from the low mortality population and 308 from the high mortality population were studied, as were 71 patients with stomach cancer. We measured serum immunoglobulin G antibody to H. pylori and serum mutant p53 protein and ceruloplasmin. RESULTS: The difference between the two populations in the prevalence of H. pylori infection was significant (p < 0.001). Of the seropositive, 81% had elevated values of mutant p53, in comparison with 11% of the seronegative (p < 0.0001). Serum concentration of ceruloplasmin was significantly higher in seropositive with elevated mutant p53 protein than in seronegative with normal levels of p53 (p < 0.05). CONCLUSIONS: There is a significant association between infection with H. pylori, elevated titers of H. pylori antibodies, and positivity for serum mutant p53 protein. Such information can significantly increase our basic knowledge in molecular pathology of gastric cancer and protection against H. pylori infection.

Metabolic profile of breast cancer in a population of women in southern Spain.

BACKGROUND: There are indications that mortality in breast cancer is related with dietary factors, but no study has been large enough to characterise reliably how, this risk is influenced. To establish a logistic regression equation that would predict breast cancer from factors in the endocrinological and metabolic profile, we studied endocrinological and metabolic risk factors that are modified by the diet, in a population of women with breast cancer in southern Spain. PATIENTS AND METHODS: We carried out a simple a case-control study comparing 204 women with breast cancer (96 premenopausal and 108 postmenopausal women) and 250 healthy control subjects. The predictive variables were basal glycaemia, insulin, glycosylated haemoglobin (HbA1c), C-peptide, insulin-like growth factor-I (IGF-I), total cholesterol, triglycerides, high density lipoprotein-c (HDL-C), low density lipoprotein-c (LDL-C), selenium and Quetelet index (BMI). RESULTS: The metabolic profile differed between pre- and postmenopausal patients, and metabolic alterations were greater in postmenopausal than in premenopausal women. The differences between healthy subjects and breast cancer patients were clearly significant. CONCLUSIONS: Our findings have several potential practical applications in the early detection of breast cancer, especially in premenopausal women; in primary prevention; and in the development of a mathematical model of breast carcinogenesis.

Selenium in breast cancer.

AIM: Controversy surrounds the hypothetical relationship between low serum levels of selenium and reduced activity of selenium-dependent enzymes, such as glutathione peroxidase, and an increased risk of cancer in humans. This study investigated serum concentrations of selenium in women with and without breast cancer. METHODS: In this case-control study, we compared serum concentrations of selenium in women with breast cancer (n = 200), healthy women (n = 100), and women with chronic diseases (n = 100). Patients with breast cancer were divided into premenopausal (n = 99) and postmenopausal subjects (n = 101). RESULTS: Mean serum concentrations of selenium were 81.1 microg/l in women with breast cancer and 98.5 microg/l in women with non-tumoral disease (p < 0.001). CONCLUSION: Alterations in serum concentrations of selenium in women with breast cancer appear to be a consequence, rather than a cause of cancer. In accordance with the hypothesis, the findings suggest that very low selenium status could be due to the nature of cancer.
