One-year outcomes following a hypertensive urgency or emergency.

There are scarce data on the comparative prognosis between patients with hypertensive emergencies (HE), urgencies (HU), and those without HU or HE (HP). Our study aimed to compare cardiovascular (CV) outcomes of HE, HU, and HP during a 12-month follow-up period. The population consisted of 353 consecutive patients presenting with HE or HU in a third-care emergency department and subsequently referred to our hypertension center for follow-up. After both groups completed scheduled follow-up visits, patients with HU were matched one-to-one by age, sex, and hypertension history with HP who attended our hypertension center during the same period. Primary outcomes were 1) a recurrent hypertensive HU or HE event and 2) non-fatal CV events (coronary heart disease, stroke, heart failure, or CV interventions), while secondary outcomes were 1) all-cause death, 2) CV death, 3) non-CV death, and 4) any-cause hospitalization. Events were prospectively registered for all three groups. During the study period, 81 patients were excluded for not completing follow-up. Among eligible patients(HE = 94; HU = 178), a total of 90 hospitalizations and 14 deaths were recorded; HE registered greater CV morbidity when compared with HU (29 vs. 9, HR 3.43, 95 % CI 1.7-6.9, p = 0.001), and increased CV mortality (8 vs. 1, HR 13.2, 95 % CI 1.57-110.8, p = 0.017). When opposing HU to HP, events did not differ substantially. Cox regression models were adjusted for age, sex, CV and chronic kidney disease, diabetes mellitus, and smoking. During 1-year follow-up, the prognosis of HU was better than HE but not different compared to HP. These results highlight the need for improved care of HU and HE.

Sex-related cardiovascular prognosis in patients with hypertensive emergencies: a 12-month study.

Current evidence on the prognosis of patients with a hypertensive crisis and predisposing factors is limited. We registered the clinical phenotype of patients with HC admitted to the emergency department, while those with a hypertensive emergency (HE) were hospitalized. One-year outcomes, i.e., composite of death or cardiovascular hospitalizations, were determined in patients with HE after hospital discharge. Out of 38,589 patients assessed in the emergency department, 256 hypertensive urgencies and 97 HE was registered. After stratification of the HE by sex, 48 men and 46 women completed the one-year follow-up. Men had more events than women (27 vs. 13, Ηazard Ratio 2.2, 95% Confidence Interval 1.03-4.7, p = 0.042) after adjustment for age, cardiovascular or chronic kidney disease, and diabetes mellitus. Our study raises the hypothesis that the male sex is an independent risk factor for cardiovascular outcomes in HE patients. CV Cardiovascular, BP blood pressure. The diagram presents the groups of comparison, men versus women in hypertensive emergencies that completed the 1-year follow-up for outcomes, in terms of hospitalizations or deaths.

Lipoprotein-associated Phospholipase A2 in Coronary Artery Disease.

Coronary artery disease (CAD) is the leading cause of morbidity and mortality in western societies. Therefore the identification of novel biomarkers to be used as diagnostic or therapeutic targets is of significant scientific interest. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is one such protein shown to be involved in endothelial dysfunction, vascular inflammation and atherogenesis. Several epidemiological studies have associated high Lp-PLA2 activity with an increased risk for CAD even when other CAD risk factors or inflammation markers were included in the multivariate analysis. These findings were strengthened by the results of relevant meta-analyses. However, randomized trials failed to establish Lp-PLA2 as a therapeutic target. Specifically, pharmaceutical inhibition of Lp-PLA2 when compared to the placebo failed to demonstrate a significant association with improved prognosis of patients with stable CAD or after an acute coronary syndrome (ACS). This review focuses on the available data that have investigated the potential role of Lp- PLA2 as a biomarker for CAD.

A case of adenoviral covid-19 vector vaccine possibly linked to severe but reversible interstitial lung injury post-vaccination.

BACKGROUND: Several safe and effective vaccines against nCoV-19 have been developed to contain the pandemic with very few severe adverse-reactions reported. Vaccine-induced interstitial lung disease (ILD) is a very rare and difficult to recognise and diagnose adverse-reaction and is mostly associated with Influenza vaccines. METHODS: We report a 55-yr old male who presented with severe respiratory failure that required for several days oxygen supplementation with high flow nasal cannula, and myocardial infarction. Symptoms onset was eighteen days after the first shot of adenoviral AZD1222 vector vaccine. Possible SARS-CoV-2 natural infection post-vaccination was excluded with rigorous laboratory work-up including multiple nasopharengeal rt-qPCR tests for SARS-CoV-2 detection and close monitoring of his serum SARS-CoV-2 antibodies. Other potential infectious agents and alternate diagnoses were thoroughly investigated. RESULTS: Patient responded impressively to high dose steroids. A repeat chest CT nine days after the first one showed a remarkable resolution of the bilateral ground glass opacities. Except for his cardiology medication, no supplemental oxygen neither steroids were prescribed upon his discharge. On one month follow-up, no residual pulmonary dysfunction was noticed with patient preserving a SatO2 of 97-98% on ambient air. CONCLUSION: Vaccine-induced ILD might constitute a rare nCoV-19 post-vaccination adverse-event. According to current restricted data, when post-vaccination ILD is early suspected and recognised, then prompt implementation of steroid treatment reverses significantly the lung lesions without progression to fibrosis.

Fluid and Salt Balance and the Role of Nutrition in Heart Failure.

The main challenges in heart failure (HF) treatment are to manage patients with refractory acute decompensated HF and to stabilize the clinical status of a patient with chronic heart failure. Beyond the use of medications targeted in the inhibition of the neurohormonal system, the balance of salt and fluid plays an important role in the maintenance of clinical compensation in respect of renal function. In the case of heart failure, a debate of opinion exists on salt restriction. Restricted dietary sodium might lead to worse outcomes in heart failure patients due to the activation of the neurohormonal system and malnutrition. On the contrary, positive sodium balance is the primary driver of water retention and, ultimately, volume overload in acute HF. Some recent studies reported associations of decreased salt consumption with higher readmission rates and increased mortality. Thus, the usefulness of salt restriction in heart failure management remains debated. The use of individualized nutritional support, compared with standard hospital food, was effective in reducing these risks, particularly in the group of patients at high nutritional risk.

Long-Term Survival under Arterial Chemoembolization and Sorafenib of a Patient with Hepatocellular Carcinoma and Tumor Atrial Thrombus: A Case Report and Literature Review.

Hepatocellular carcinoma (HCC) is considered to be the fourth most frequent cause of cancer-associated death globally. HCC might be associated, especially in advanced stages, with the formation of tumor thrombus (TT), which can be located in the portal vein, as well as in hepatic and/or inferior vena cava (IVC) veins. Nevertheless, the extension of TT to the right atrium (RA) is infrequent with an unfavorable prognosis. We present a rare case of a male patient with HCC and IVC TT extending to the RA. The atrial thrombus was the first manifestation of HCC diagnosed by cardiac ultrasound. So far, the patient has undergone 4 courses of transarterial chemoembolization in combination with systemic therapy with sorafenib, and under this therapeutic approach long-term survival has been achieved.

Intravenous plus inhaled versus intravenous colistin monotherapy for lower respiratory tract infections: A systematic review and meta-analysis.

OBJECTIVE: To evaluate whether intravenous plus inhaled combination (IV/INHCC) compared to intravenous monotherapy (IVCM) was associated with patient outcomes and identify factors influencing study outcomes. METHODS: PubMed and Scopus were searched till November 2016. Studies were included if they evaluated adult patients with lower respiratory tract infections due to MDR/XDR Gram-negative bacteria and reported comparative mortality data (adjusted and unadjusted) for patients receiving IV/INHCC versus IVCM. Random effects meta-analyses were performed. RESULTS: Thirteen studies (11 retrospective, 2 prospective) were included. The overall quality of data was low to very low and characterized by the lack of adjusted data. The majority of the studies were designed to evaluate the outcome of the meta-analysis. Both IV and inhaled colistin were administered at variable doses. There was no difference in mortality between IV/INHCC and IVCM when all studies were combined (13 studies, 1115 patients, risk ratio 0.94, 95% confidence interval 0.81-1.08). Only the analysis that included studies with low-dose IV colistin showed significant difference in favor of IV/INHCC versus IVCM (0.65, 0.45-0.94). CONCLUSIONS: Overall, low quality data suggest that IV/INHCC did not lower mortality in patients with MDR Gram negative infections unless low IV colistin dose was administered.

Intravenous colistin combination antimicrobial treatment vs. monotherapy: a systematic review and meta-analysis.

BACKGROUND: To evaluate whether intravenous colistin in combination with other antibiotics (IVCC) is associated with lower mortality compared with intravenous colistin monotherapy (IVCM), and to identify factors influencing study outcomes. METHODS: PubMed and Scopus were searched up to November 2016. Studies were included if they evaluated adult patients with multi-drug-resistant (MDR) or extensively-drug-resistant Gram-negative infections, and reported comparative mortality data (adjusted and unadjusted) for patients receiving IVCC vs. IVCM. Random effects meta-analyses were performed. FINDINGS: Thirty-two studies (29 observational, three randomized) were included. The overall quality of data was low to very low, and studies were characterized by the lack of adjusted data. The majority of studies were not designed to evaluate the outcome of the meta-analysis, and focused mainly on infections due to Acinetobacter baumannii and Klebsiella pneumoniae. Colistin was administered at variable doses, with or without a loading dose, and in combination with several antibiotics. Overall, IVCC was not associated with lower mortality than IVCM [32 studies, 2328 patients, risk ratio (RR) 0.91, 95% confidence interval (CI) 0.81-1.02, I2 8%]. A significant difference was observed in favour of IVCC when high-dose (>6 million international units) colistin was used (RR 0.80, 95% CI 0.69-0.93), in studies conducted in Asia (RR 0.82, 95% CI 0.71-0.95), in patients with bacteraemia (RR 0.75, 95% CI 0.57-0.98) and in patients with acinetobacter infections (RR 0.88, 95% CI 0.78-1.00). INTERPRETATION: Overall, low-quality data suggest that IVCC did not lower mortality in patients with MDR Gram-negative infections. However, there is some evidence for a benefit observed with high intravenous doses of colistin.

The antibiotic pipeline for multi-drug resistant gram negative bacteria: what can we expect?

INTRODUCTION: A real concern in the medical community is the increasing resistance of bacteria, especially that of Gram-negative types. New antibiotics are currently under clinical development, promising to tackle severe infections caused, especially, by multi-drug resistant (MDR) bacteria and broaden the armamentarium of clinicians. AREAS COVERED: We searched PUBMED and GOOGLE databases. Combinations of already approved ß-lactams or monobactams with new ß-lactamase inhibitors [imipenem-cilastatin/MK-7655 (relebactam), meropenem/RPX7009 (vaborbactam), ceftaroline/avibactam, aztreonam/avibactam], new ß-lactams (S-649266, BAL30072), aminoglycosides (plazomicin), quinolones (finafloxacin) and tetracyclines (eravacycline) were included in the review. Expert commentary: For the majority of the upcoming antibiotics the currently available data is limited to their microbiology and pharmacokinetics. Their effectiveness and safety against infections due to MDR bacteria remain to be proved. Significant issues are also the impact of these antibiotics on the human intestinal microbiota and their possible co-administration with already-known antimicrobial agents in difficult-to-treat-infections; further studies should be conducted for these objectives.
