The Cardiac Pulsed Wave Doppler Pattern of the Common Femoral Vein in Diagnosing the Likelihood of Severe Pulmonary Hypertension: Results from a Prospective Multicentric Study.

Background and Objectives: Pulmonary hypertension (PH) is a clinical condition with high mortality rates, particularly in patients over 65. Current guidelines recommend assessing the likelihood of pulmonary hypertension (LPH) using advanced echocardiography before proceeding to right heart catheterization. This study proposed using the common femoral vein (CFV), an accessible vein that reflects right atrial pressure, as an alternative method to assess the high likelihood of pulmonary hypertension (H-LPH). Materials and Methods: This prospective observational study included 175 emergency patients from three hospitals. Ultrasound assessed the pulsed wave Doppler (PW-Doppler) morphology of the CFV. This diagnostic yield for H-LPH was evaluated alongside traditional ultrasound parameters (right-to-left ventricular basal diameter ratio greater than 1 (RV > LV), septal flattening, right ventricular outflow acceleration time (RVOT) of less than 105 ms and/or mesosystolic notching, pulmonary artery diameter greater than the aortic root (AR) diameter or over 25 mm, early pulmonary regurgitation maximum velocity > 2.2 m/s; TAPSE/PASP less than 0.55, inferior vena cava (IVC) diameter over 21 mm with decreased inspiratory collapse, and right atrial (RA) area over 18 cm2). Results: The CFV's PW-Doppler cardiac pattern correlated strongly with H-LPH, showing a sensitivity (Sn) of 72% and a specificity (Sp) of 96%. RA dilation and TAPSE/PASP < 0.55 also played significant diagnostic roles. Conclusions: The CFV's PW-Doppler cardiac pattern is an effective indicator of H-LPH, allowing reliable exclusion of this condition when absent. This approach could simplify initial LPH evaluation in emergency settings or where echocardiographic resources are limited.

Usefulness of Serial Multiorgan Point-of-Care Ultrasound in Acute Heart Failure: Results from a Prospective Observational Cohort.

Background and Objectives: Acute heart failure (AHF) is a common disease and a cause of high morbidity and mortality, constituting a major health problem. The main purpose of this study was to determine the impact of multiorgan ultrasound in identifying pulmonary hypertension (PH), a major prognostic factor in patients admitted due to AHF, and assess whether there are significant changes in the venous excess ultrasonography (VE × US) score or femoral vein Doppler at discharge. Materials and Methods: Patients were evaluated with a standard protocol of lung ultrasound, echocardiography, inferior vena cava (IVC) and hepatic, portal, intra-renal and femoral vein Doppler flow patterns at admission and on the day of discharge. Results: Thirty patients were enrolled during November 2021. The mean age was seventy-nine years (Standard Deviation-SD 13.4). Seven patients (23.3%) had a worsening renal function during hospitalization. Regarding ultrasound findings, VE × US score was calculated at admission and at discharge, unexpectedly remaining unchanged or even worsened (21 patients, 70.0%). The area under the curve for the lung score was 83.9% (p = 0.008), obtaining a cutoff value of 10 that showed a sensitivity of 82.6% and a specificity of 71.4% in the identification of intermediate and high PH. It was possible to monitor significant changes between both exams on the lung score (16.5 vs. 9.3; p < 0.001), improvement in the hepatic vein Doppler pattern (2.4 vs. 2.1; p = 0.002), improvement in portal vein Doppler pattern (1.7 vs. 1.4; p = 0.023), without significant changes in the intra-renal vein Doppler pattern (1.70 vs. 1.57; p = 0.293), VE × US score (1.3 vs. 1.1; p = 0.501), femoral vein Doppler pattern (2.4 vs. 2.1; p = 0.161) and IVC collapsibility (2.0 vs. 2.1; p = 0.420). Conclusions: Our study results suggest that performing serial multiorgan Point-of-Care ultrasound can help us to better identify high and intermediate probability of PH patients with AHF. Currently proposed multi-organ, venous Doppler scanning protocols, such as the VE × US score, should be further studied before expanding its use in AHF patients.

Streptococcus bovis bacteraemia revisited: clinical and microbiological correlates in a contemporary series of 59 patients.

OBJECTIVE: To characterise the clinical features, associations and outcome in a contemporary series of patients with Streptococcus bovis bacteraemia (SBB). METHODS: Retrospective analysis of all episodes of SBB at the University Hospital 12 de Octubre (Madrid, Spain) between January 1997 and November 2008 was performed. Patient data were reviewed, focusing on clinical and microbiological associations with the different biotypes of S. bovis. RESULTS: Fifty-nine episodes of SBB were documented in 59 adult patients (30 males; mean age: 70.9 ± 15.0 years). Chronic liver disease was identified in 20 patients (33.9%). Sixteen patients (27.1%) presented infective endocarditis (IE) and 14 (23.7%) had a biliary source of bacteraemia. Thirty-three patients (55.9%) underwent colonic evaluation, adenomatous polyps being the most common finding (21 patients). Malignancy was diagnosed following SBB in 9 cases, including 6 patients with colorectal carcinoma (18.2% of those who underwent colonic evaluation). Of 22 isolates biotyped, 12 were S. bovis biotype I and 10 were S. bovis biotype II. IE was more frequent among patients with S. bovis biotype I (P =0.010), whereas bacteraemia due to biotype II species was more likely to be of biliary origin (P=0.078). CONCLUSIONS: S. bovis biotyping identifies some clinically relevant associations.

Multiple primary malignancies in Spanish patients with hepatocellular carcinoma: analysis of a hospital-based tumor registry.

BACKGROUND AND AIM: Little is known about the etiological associations and clinical features of extrahepatic primary malignant (EHPM) neoplasms in subjects with hepatocellular carcinoma (HCC). The aim of this study was to characterize this phenomenon in a consecutive series of Spanish patients in order to define its natural history and influence on survival. METHODS: A retrospective analysis of 245 patients with HCC during the period 1999-2003 was performed. Subjects identified with a second primary malignancy elsewhere constituted the EHPM group and were compared to patients with HCC alone. RESULTS: Eighteen patients (7.3%) had one or two associated extrahepatic malignancies (mean age 67.7 +/- 9.7 years); of these, 17 had double cancer and one patient, triple. Nine of the 19 EHPM occurred before HCC diagnosis. The associated cancers included five cases of colorectal carcinoma, four cases of head and neck carcinoma, three cases of genitourinary cancer, two cases of lymphoproliferative disorder, one lung carcinoma, one skin melanoma, one breast carcinoma, and two cancers of unknown origin. Age and sex distribution, etiology of underlying hepatopathy, and liver function tests did not differ significantly between both groups. There was no difference between the overall survival rates. CONCLUSIONS: EHPM is not rare among Spanish patients with HCC, although no specific clinicopathological features were detected in this population. Our results suggest that the association of another primary tumor with HCC does not imply a worse prognosis. The possibility of development of EHPM should be kept in mind when deciding on therapy and follow-up of HCC.
