The Prognostic Value of Pulmonary Venous Flow Reversal in Patients with Significant Degenerative Mitral Regurgitation.

Background: The prognostic significance of pulmonary venous (PV) flow reversal in degenerative mitral regurgitation (dMR) is not well-established. Objective: We aimed to assess whether reversed PV flow is associated with adverse outcomes in patients with significant dMR. Methods: We retrospectively analyzed consecutive patients referred to a tertiary center for evaluation of dMR of greater than moderate degree, who had normal sinus rhythm, had a left ventricular ejection fraction of above 60%, and did not suffer from any other major valvular disorders. The primary outcome was the combined rate of all-cause mortality, mitral intervention, or new-onset atrial fibrillation (AF) at 5 years following index echocardiogram. Secondary outcomes included individual components of the primary outcome. Results: Overall, 135 patients (median age 68 (IQR, 58-74) years; 93 (68.9%) males; 89 (65.9%) with severe MR) met the inclusion criteria and were followed for 115.2 (IQR, 60.0-155.0) months. Patients with a reversed PV flow pattern (PVFP) (n = 34) more often presented with severe MR compared to those with a normal (n = 49) and non-reversed PVFP (n = 101) (RR = 2.03 and 1.59, respectively, all p < 0.001). At 5 years, they experienced the highest cumulative incidence of the primary outcome (80.2% vs. 59.2% and 67.3%, p = 0.008 and 0.018, respectively). Furthermore, a reversed PVFP was independently associated with a higher risk of the primary outcome compared to normal PVFP (HR 2.53, 95% CI 1.21-5.31, p = 0.011) and non-reversed PVFP (HR 2.14, 95% CI 1.12-4.10, p = 0.022). Conclusion: PV flow reversal is associated with a worse 5-year composite of mortality, mitral intervention, or AF in patients with significant dMR.

Current challenges in the diagnosis and management of acute coronary syndromes in women.

Cardiovascular disease remains the leading cause of death among women nowadays. However, there is a persistent lack of awareness of the impact of different risk factors on women's cardiovascular health, in specific pregnancy-related complications, hormonal changes, and psychological aspects. Moreover, there is still not enough awareness of the importance of coronary artery disease (CAD) in women, which leads to a delay in the diagnosis and prompt treatment, particularly during emergent coronary scenarios. Although guidelines suggest the same treatment for women and men who present with acute coronary syndrome (ACS), women are still undertreated. Contemporary data show an improvement over time in the management of ACS in women, however, women are still less likely than men to receive revascularization and pharmacological treatments. Women have higher rates of complications and mortality, in particular the young population, in which all outcomes are still worse in women compared to men. In this review, we aim to emphasize the importance of women's risk factors, women-specific pathophysiology, and clinical presentation in the setting of ACS. This is a review of current challenges in the diagnosis and treatment of women with ACS.

Secondary organizing pneumonia after recovery of mild COVID-19 infection.

A 36-year-old male with diffuse large B-cell lymphoma on maintenance rituximab therapy presented to the emergency department with high fever and fatigue. A chest X-ray showed a lobar infiltrate, 40 days before admission the patient suffered from a mild coronavirus disease 2019 (COVID-19) infection and fully recovered. PCR nasopharyngeal swab was negative for COVID-19. Comprehensive biochemical, radiological, and pathological evaluation including 18-fluorodeoxyglucose positron emission tomography with computed tomography and transbronchial lung biopsy found no pathogen or lymphoma recurrence. Treatment for pneumonia with antibiotic and antifungal agents was nonbeneficial. A diagnosis of secondary organizing pneumonia (OP) was made after pneumonia migration and a rapid response to corticosteroids. OP secondary to a viral respiratory infection has been well described. Raising awareness for post-COVID-19 OP has therapeutic and prognostic importance because those patients benefit from steroid therapy. We believe the condition described here is underdiagnosed and undertreated by doctors worldwide. Because of the ongoing global pandemic we are now encountering a new kind of patient, patients that have recovered from COVID-19. We hope that this case may contribute to gaining more knowledge about this growing patient population.

[ETHNIC DIVERSITY AND CLINICAL CHARACTERISTICS OF HOSPITALIZED PATIENTS WITH ACUTE PANCREATITIS].

BACKGROUND: Previous studies have shown a correlation between acute pancreatitis and several different risk factors that vary in different countries and ethnic groups. The aims of this study are to examine the clinical characteristics and outcomes of acute pancreatitis in patients of Jewish and Bedouin origin. METHODS: We performed a retrospective cohort study of patients hospitalized with acute pancreatitis in the Soroka University Medical Center between the years 2012 and 2016 and compared two groups of patients: patients of Jewish and Bedouin origin. The primary outcome was a composite outcome consisting of 30-days mortality, ICU admission, complications (defined as necrotizing pancreatitis or pseudocyst formation), surgery due to these complications and 30-days re-admission due to pancreatitis. RESULTS: A total of 560 patients were included, 483 patients (86.3%) of Jewish origin and 77 patients (13.7%) of Bedouin origin. The most common cause in both groups was biliary pancreatitis: 49.7% among Jewish, 61% among Bedouin. In our study alcohol consumption, the most common worldwide risk factor of pancreatitis, accounts for only a small percentage of the disease in the Jewish population (5.6%) and does not exist in the Bedouin population. We found no significant differences in outcomes between the two groups. CONCLUSIONS: Biliary pancreatitis was the most common cause in both groups of patients. The important finding of our study is that alcohol use is a minor cause of acute pancreatitis in the Negev. Moreover, it is uncommon in the Jewish population and is completely non-existent among Bedouins. No differences were found in the primary outcomes between the two groups.

Hemoglobin A1c in Patients with Diabetes Predict Long-Term Mortality Following Coronary Artery Surgery.

OBJECTIVE: to estimate the association between preoperative hemoglobin A1c (HbA1c) levels below and above 7%, and the rate of all-cause mortality (ACM) in diabetes mellitus (DM) patients after coronary artery bypass grafting (CABG) within a ten-year follow-up period. METHODS: we collected data on patient HbA1c levels that were measured up to 3 months prior to isolated CABG in consecutive patients with DM, and analyzed the rates of ACM over a median of a 5.9-year post-operative period. RESULTS: preoperative HbA1c levels were collected in 579 DM patients. The mean HbA1c was 8.0 ± 1.7%, where 206 (35.6%) patients had an HbA1c ≤ 7% and 373 (64.4%) had an HbA1c > 7%. During the follow-up period, mortality rates were 20.4% and 28.7% in the HbA1c ≤ 7% and HbA1c > 7% groups, respectively (Kaplan-Meier estimates, log-rank p = 0.01). Multivariable Cox proportional hazards regression, adjusted for age, gender, smoking status, chronic obstructive pulmonary disease, hypertension, chronic renal failure, old myocardial infarction, number of coronary artery bypass surgeries, and post-operative glycemic control, showed a hazard ratio of 2.67 for long-term ACM (p = 0.001) in patients with HbA1c > 7%. CONCLUSIONS: DM patients with high HbA1c levels prior to CABG are at higher risk for long-term complications, especially late ACM.

Sex Differences in Infective Endocarditis.

BACKGROUND: The impact of sex on the presentation, etiology, and outcomes of infective endocarditis (IE) has not been adequately studied. The aim of the present research was to analyze the impact of sex on the presentation, etiology, and outcomes of IE. METHODS: We performed a retrospective study of 214 adult patients (131 male and 83 female) with IE. All cases of IE were reviewed by two investigators- both senior physicians in internal medicine. Two groups of patients were compared: male and female patients with IE. The primary outcome was in-hospital mortality. RESULTS: We found significant differences in etiologic factors of IE in male and female patients. Microbiologic etiology differences between male and female groups of patients were in coagulase negative staphylococcus (15.0% in male vs 3.8% in female groups, P = 0.011), and culture negative endocarditis (8.7% in male vs 23.8% in female groups, P = 0.004). We did not find a difference in the primary outcome between the two groups; however, all-cause mortality was significantly higher in the female group as compared to the male group (26 [31.3] vs 22 [16.8], P = 0.018). CONCLUSIONS: We found that sex may have important role in both the microbial profile and the patient's outcome with IE.

Dabigatran-induced nephropathy and its successful treatment with Idarucizumab - case report and literature review.

BACKGROUND: Anticoagulant induced renal injury has been previously described with Warfarin treatment. In the last decade direct oral anticoagulants (DOAC) were introduced. They include direct inhibitors of factor Xa (Rivaroxaban, Apixaban, Edoxaban) and a thrombin inhibitor (Dabigatran). There are isolated reports describing acute kidney injury (AKI) due to the use of DOACs. CASE REPORT: We report a clinical case of an 80-year-old patient recently started on Dabigatran for new onset atrial fibrillation. She presented with AKI and hematuria, urine specimen showed RBC casts, and a working diagnosis of anticoagulant nephropathy due to Dabigatran was made. During hospitalization she was treated with Idarucizumab with a full recovery of renal function. To the best of our knowledge, there are 4 published case reports describing kidney injury produced by Dabigatran. CONCLUSION: The use of DOACs is increasing rapidly, with increasing concern about its safety profile and, in particular, its potential harmful effect on renal function. As described in our case, treatment with Praxbind for Dabigatran induced kidney injury may be an acceptable management strategy that may obviate the need for urgent dialysis in selected cases by complete reversal of the AKI.
