Clinical outcomes between direct oral anticoagulants versus vitamin K antagonists in chronic thromboembolic pulmonary hypertension: A systematic review and meta-analysis.

Pulmonary hypertension (PH) is a known chronic condition that can lead to increased morbidity and mortality. Patients who develop PH due to thromboembolic disease are catalogued as chronic thromboembolic pulmonary hypertension (CTEPH). Anticoagulation remains a topic of interest in these patients. PUBMED, EMBASE and COCHRANE databases were searched by two investigators until December 2023. Information was analyzed for all-cause mortality, venous thromboembolism and major bleeding. We included a total of 10 studies in this meta-analysis. Our pooled analysis demonstrated that DOACs were non-inferior in all-cause mortality [OR 0.88, 95 % CI (0.48, 1.61)], venous thromboembolism [OR 1.00, 95 % CI (0.50, 1.98)] and major bleeding [OR 0.78, 95 % CI (0.43, 1.40)] when compared to VKAs. In conclusion, our meta-analysis supports the use of DOACs in patients with CTEPH. Further randomized trials are still needed to confirm our results in terms of safety and mortality.

Transcatheter Vacuum-Assisted Mass Extraction Versus Surgical Debridement for Vegetations in Tricuspid Valve Infective Endocarditis: A Meta-Analysis of Observational Studies.

Tricuspid valve infective endocarditis (TVIE), often associated with vegetation in people who inject drugs, has introduced a less invasive option for vegetation removal: transcatheter vacuum-assisted mass extraction (TVME). This technique is emerging as an alternative to standard surgical debridement (SD) and valve repair. However, the comparative effectiveness of TVME versus SD in treating TVIE has yet to be investigated. A comprehensive systematic literature search was performed on PubMed, Embase, and Cochrane to identify all relevant studies comparing TVME with SD in patients with TVIE. The search covered studies from inception up to August 15, 2023. For data analysis, Review Manager (RevMan) 5.4 software was employed, using a random-effects model to calculate risk ratios (RRs), mean differences, and 95% confidence intervals (CIs). Five studies included a total of 431 patients (244 in the TVME arm and 187 in the SD arm). In-hospital mortality (p = 0.72), procedural mortality (p = 0.77), 30-day mortality (p = 0.25), and 1-year mortality (p = 0.44) insignificantly favored SD over TVME. Overall mortality across the 5 studies insignificantly favored TVME over SD (RR = 0.66, 95% CI 0.31 to 1.39, p = 0.27, I2 = 57%). When addressing heterogeneity by excluding 1 study, no statistical significance in the difference between the 2 arms regarding overall mortality was observed (RR 0.99, 95% CI 0.60 to 1.63, p = 0.97, I2 = 0%). This meta-analysis of the 5 observational studies found no significant difference in overall mortality between TVME and SD for the treatment of TVIE. However, prospective randomized controlled trials are necessary to further understand and compare the outcomes of these 2 approaches.

Venous Thromboembolism Risk Assessment in Hospitalized Cancer Patients: A Single Center Study.

This study aimed to identify predictors of venous thromboembolism (VTE) in hospitalized cancer patients and develop a predictive model using demographic, clinical, and laboratory data. Our analysis showed that patient groups categorized under a very high risk, and high risk, patients with low hemoglobin levels and renal disease were at a significantly increased risk of developing VTE. We developed a VTE risk-assessment model (RAM) with moderate discriminatory performance, high specificity, and negative predictive value, indicating its potential utility in identifying patients without VTE risk. However, the model's positive predictive value and sensitivity were low due to the low prevalence of VTE within the analyzed population. Future studies are needed to analyze additional predictive factors, and to validate the effectiveness of our VTE RAM to safely rule out VTE, compare it with other VTE RAMs in hospitalized cancer patients, and address any limitations of our study.

Unusual Presentation and Outcome in Acute Cocaine Intoxication With Multiorgan Failure: A Case Report.

Cocaine overdose remains a significant public health concern worldwide, with potentially life-threatening consequences. The range of presentation can vary from mild autonomic hyperactivity to severe vasoconstriction, causing multiorgan ischemia and even death. In cases of high-dose intoxication, the presentation can be atypical. In this case report, we present a compelling case of a patient who initially presented with cardiac arrest and atypical signs. The patient made a remarkable recovery and returned almost to her baseline. This case provides valuable prognostic insight into the outcomes of severe multiorgan failure resulting from cocaine toxicity.

Alcohol Use Disorder Admissions During the COVID-19 Pandemic: Findings From a Tertiary Community Hospital.

OBJECTIVES: The first case of Coronavirus disease-19 (COVID-19) in the United States was confirmed by the Centers for Disease Control (CDC) in January 2020. The presence of COVID-19 and the subsequent spread of this disease led to stress, anxiety, grief, and worry. We aimed to study the rate of hospital admission for alcohol use disorder (AUD) before and during the COVID-19 pandemic in a tertiary community hospital in Michigan. METHODS: Two subsets of hospital data were collected for comparison between hospitalized patients before and during the pandemic in a tertiary community hospital. Logistic regression was used to identify the odds ratio of AUD admission rates among all patients in 2020 compared with 2019 while controlling for covariates. RESULTS: Our data showed a statistically significant increase in AUD patients in 2020 compared to 2019 (3.26% versus 2.50%, adjusted OR=1.44 with P=0.002). In addition, females had significantly lower chances of admission for AUD compared with males (OR=0.22 with P<0.001) and African Americans had significantly lower chances of admission for AUD compared to Whites (OR=0.44 with P <0.001). Divorced patients had a higher probability of admission for AUD compared to married patients (OR=2.62 with P<0.001). CONCLUSION: Our study found a significantly higher rate of AUD admissions in 2020 during the COVID-19 Pandemic compared to 2019. Gender, race, age, and marital status are significant risk factors related to AUD admissions.

Left Atrial Appendage Closure Versus Oral Anticoagulation in Non-Valvular Atrial Fibrillation: A Systematic Review and Meta-Analysis.

BACKGROUND: Left atrial appendage closure (LAAC) devices are an alternative therapy in non-valvular atrial fibrillation (NVAF) patients with contraindications to oral anticoagulation (OAC). However, there are limited data about the clinical outcomes of LAAC devices compared to medical treatment. METHODS: A comprehensive research for studies comparing LAAC devices and OAC for patients with NVAF was performed from inception to January 1, 2021. A meta-analysis was performed using a random effect model to calculate odds ratios (OR) with 95% confidence intervals (CIs). RESULTS: Five studies were eligible that included a total of 4778 patients with a median-weighted follow-up period was 2.6 years. Compared to OAC, the LAAC device arm was associated with a lower risk of the composite of stroke, systemic embolism, and cardiovascular death (OR 0.71; 95% CI 0.51-1.00; p = 0.05). LAAC device arm was also associated with a lower risk of all-cause mortality (OR of 0.60, 95% CI 0.46-0.77; p < 0.0001), cardiovascular mortality (OR of 0.57, 95% CI 0.46-0.70; p < 0.00001), hemorrhagic stroke (OR of 0.19, 95% CI 0.07-0.50; p= 0.0006), all major bleeding (OR of 0.61, 95% CI 0.43-0.88; p = 0.007) and non-procedural major bleeding (OR of 0.46, 95% CI 0.32-0.65; p < 0.0001). There was no significant difference in all stroke, ischemic stroke, and systemic embolization between the two groups. CONCLUSIONS: Our meta-analysis showed lower all-cause mortality, cardiovascular mortality, hemorrhagic stroke, major bleeding, non-procedural major bleeding and the composite of stroke, systemic embolism, and cardiovascular death in the LAAC device arm when compared to OAC. However, the risk of all stroke, ischemic stroke, and systemic embolism were similar between the two arms.

Meta-Analysis of Valve-in-Valve Transcatheter Aortic Valve Implantation Versus Redo-surgical Aortic Valve Replacement in Failed Bioprosthetic Aortic Valve.

This meta-analysis was conducted to compare clinical outcomes of valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) versus redo-surgical aortic valve replacement (Redo-SAVR) in failed bioprosthetic aortic valves. We conducted a comprehensive review of previous publications of all relevant studies through August 2020. Twelve observational studies were included with a total of 8,430 patients, and a median-weighted follow-up period of 1.74 years. A pooled analysis of the data showed no significant difference in all-cause mortality (OR 1.15; 95% CI 0.93 to 1.43; p = 0.21), cardiovascular mortality, myocardial infarction, permanent pacemaker implantation, and the rate of moderate to severe paravalvular leakage between ViV-TAVI and Redo-SAVR groups. The rate of major bleeding (OR 0.36; 95% CI 0.16 to 0.83, p = 0.02), procedural mortality (OR 0.41; 95% CI 0.18 to 0.96, p = 0.04), 30-day mortality (OR 0.58; 95% CI 0.45 to 0.74, p <0.0001), and the rate of stroke (OR 0.65; 95% CI 0.52 to 0.81, p = 0.0001) were significantly lower in the ViV- TAVI arm when compared with Redo-SAVR arm. The mean transvalvular pressure gradient was significantly higher post-implantation in the ViV-TAVI group when compared with the Redo-SAVR arm (Mean difference 3.92; 95% CI 1.97 to 5.88, p < 0.0001). In conclusion, compared with Redo-SAVR, ViV-TAVI is associated with a similar risk of all-cause mortality, cardiovascular mortality, myocardial infarction, permanent pacemaker implantation, and the rate of moderate to severe paravalvular leakage. However, the rate of major bleeding, stroke, procedural mortality and 30-day mortality were significantly lower in the ViV-TAVI group when compared with Redo-SAVR.

Undiagnosed sarcoidosis presenting as acute pancreatitis: a rare presentation of a known disease.

A 43-year-old African American man presented with right upper quadrant pain and elevated blood pressure. Investigations revealed elevated lipase, hypercalcaemia and elevated creatinine. CT abdomen with contrast revealed extensive intraabdominal lymphadenopathy with an initial suspicion for a lymphoproliferative malignancy. Patient was managed for acute pancreatitis, with further workup of hypercalcaemia revealing an elevated ACE level. Inguinal lymph node biopsy confirmed a non-caseating granuloma leading to the diagnosis of sarcoidosis.

Relationship between blood pressure and kidney diseases in large randomized controlled trials: secondary analyses using SPRINT and ACCORD-BP trials.

Hypertension is a risk factor for acute kidney injury. In this study, we aimed to identify the optimal blood pressure (BP) targets for CKD and non-CKD patients. We analyzed the data of the Systolic Blood Pressure Intervention Trial (SPRINT) and the Action to Control Cardiovascular Risk in Diabetes Blood Pressure trial (ACCORD BP) to determine the nonlinear relationship between BP and renal disease development using the Generalized Additive Model (GAM). Optimal systolic BP/diastolic BP (SBP/DBP) with lowest renal risk were estimated using GAM. Logistic regression was employed to find odds ratios (ORs) of adverse renal outcomes by three BP groups (high/medium/low). Both study trials have demonstrated a "U"-shaped relationship between BP and renal outcomes. For non-CKD patients in SPRINT trial, risk of 30% reduction in eGFR among intensive group patients with DBP ≤ 70 mmHg was significantly higher than the group with DBP between 71 and 85 mmHg (OR = 2.31, 95% CI = 1.51-3.53). For non-CKD patients in ACCORD trial, risk of doubling of serum creatinine (SCr) or >20 mL/min decrease in eGFR among intensive group patients with DBP ≤ 70 mmHg was significantly higher than the group with DBP between 71 and 85 mmHg (OR = 1.49, 95% CI = 1.12-1.99). For CKD patients in SPRINT trial, there are no significant differences in renal outcomes by different SBP/DBP levels. Our analysis of both SPRINT and ACCORD datasets demonstrated that lower-than-optimal DBP may lead to poor renal outcomes in non-CKD patients. Healthcare providers should be cautious of too low DBP level in intensive BP management due to poor renal outcomes for non-CKD patients.

Do USMLE steps, and ITE score predict the American Board of Internal Medicine Certifying Exam results?

BACKGROUND: To evaluate if United States Medical Licensing Examination (USMLE) Step 1, USMLE Step 2 CK, USMLE Step 3, and residency third-year in-service training exam (ITE) scores predict the results of American Board of Internal Medicine Certifying Exam (ABIM-CE). METHODS: We performed a retrospective review of USMLE Step 1, USMLE Step 2 CK, USMLE Step 3, third-year residency ITE scores and ABIM-CE results of IM residents at our residency program from 2004 through 2017. Statistical analysis was perfrormed using Pearson correlation coefficient, and logistic regression to assess the relationship between USMLE Step 1, USMLE Step 2CK, USMLE Step 3, 3rd year ITE scores and ABIM-CE results. We used Multivariate logistic regression to predict pass or fail results in ABIM-CE based on USMLE and third-year ITE test scores controlling for other covariates. RESULTS: Among 114 Internal Medicine MD residents included in the study, 92% (n = 105) passed the ABIM-CE. The OR of passing ABIM-CE was 2.70 (95% CI = 1.38-5.29), 2.31 (95% CI = 1.33-4.01), and 1.63 (95% CI = 0.81-3.29) with a ten-point increase in USMLE Step 1, USMLE Step 2 CK and USMLE Step 3 scores respectively. The OR of ABIM-CE passing chance was 2.96 (95% CI = 0.95-9.20), with a ten-point increase in the average score of the above three exams. A 5 % increase in ITE percentage raised the likelihood of passing ABIM-CE (OR 2.92, 95% CI 1.15-7.38). All residents who failed ABIM-CE had Step 1 scores < 220. Among 31 residents with Step 2 CK score < 220, 20% (n = 6) failed ABIM. Similarly, 9% of residents with USMLE Step 3 score < 220 failed ABIM-CE; all residents who failed had scored < 220. The probability curve predicted that the chance of passing ABIM- CE was around 80% with USMLE scores greater than 200 and increased to almost 100% with USMLE scores of 250 or more. CONCLUSION: USMLE Step 1, USMLE Step 2 CK, and third-year ITE scores can predict the chances of passing ABIM-CE. The third-year ITE score has a higher preditive value compared to USMLE Step 1 and USMLE Step 2 scores. USMLE Step 1 scores more predictive of ABIM-CE results compared to USMLE Step 2CK scores. Thus, residency programs can identify internal medicine residents at risk of failing ABIM-CE and formulate interventions at an early stage during residency training. Measures such as enrolling them in question banks or board review courses can be helpful in improving their chances of passing ABIM-CE.

Efficacy and safety of figure-of-eight suture versus manual pressure for venous access closure: a systematic review and meta-analysis.

BACKGROUND: Vascular hemostasis after venous access in cardiovascular procedures remains a challenge. Figure-of-eight (FoE) emerged as an alternative technique to manual pressure. However, its feasibility and safety is unknown. METHODS: A comprehensive search in clinicalTrials.gov, PubMed, Web of Science, EBSCO Services, Cochrane Central Register of Controlled Trials, Google Scholar, and various scientific conference sessions from inception to December 1, 2018, was performed. A meta-analysis was performed using random effects model to calculate risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI). RESULTS: Seven studies were eligible and included 1978 patients, of whom 982 patients received the FoE suture, while 996 received manual pressure. There was no difference in the risk of access site pseudoaneurysm (RR 0.48, 95%CI 0.13 to 1.73, p = 0.26) and fistula (RR 0.90, 95%CI 0.22 to 3.75, p = 0.89) between the two techniques. Compared with manual pressure, FoE was associated with lower risk of access site complications (RR 0.37, 95%CI 0.24 to 0.58, 0.65, p < 0.0001) including bleeding (RR 0.30, 95%CI 0.18 to 0.50, p < 0.00001) and hematoma (RR 0.41, 95%CI 0.25 to 0.68, 0.83, p = 0.0005). Time to hemostasis was significantly lower in FoE group compared with manual pressure (MD - 21.04 min, 95%CI - 35.66 to - 6.42, p = 0.005). CONCLUSIONS: The results of our meta-analysis showed that there was no difference in the risk of access site pseudoaneurysm and fistula between FoE and manual pressure. FoE was associated with lower risk of access site hematoma and bleeding compared with manual pressure. Our results reiterate the safety and feasibility of FoE suture for venous access closure.

Efficacy and safety of single vs dual antiplatelet therapy in patients on anticoagulation undergoing percutaneous coronary intervention: A systematic review and meta-analysis.

BACKGROUND: Selection of an appropriate antithrombotic regimen in patients requiring oral anticoagulation (OAC) undergoing percutaneous coronary intervention (PCI) still remains a challenge. An ideal 9-2regimen should balance the risk of bleeding against ischemic benefit. METHODS: A comprehensive literature search for studies comparing triple antithrombotic therapy (TAT) vs double antithrombotic therapy (DAT) in patients requiring OAC undergoing PCI was performed in clinicalTrials.gov, PubMed, Web of Science, EBSCO Services, Cochrane Central Register of Controlled Trials, Google Scholar, and various scientific conference sessions from inception to May 1st, 2019. A meta-analysis was performed using random-effects model to calculate risk ratio (RR) and 95% confidence interval (CI). RESULTS: Fifteen studies were eligible and included 13 967 patients, of which 7349 received TAT and 6618 received DAT. Compared with DAT, TAT was associated with lower risk of myocardial infarction (RR, 0.82; 95%CI, 0.69-0.98; P = .03) and stent thrombosis (RR, 0.66; 95%CI, 0.46-0.96; P = .03). There was no difference in risk of trial defined major adverse cardiac events, all-cause mortality, and stroke between two groups. Compared with DAT, TAT was associated with higher risk of trial defined major bleeding (RR, 1.67; 95%CI, 1.38-2.01; P < .00001), including thrombolysis in myocardial infarction major bleeding (RR, 1.81; 95%CI, 1.47-2.24; P < .00001) but no significant difference in risk of intracranial bleeding. CONCLUSION: In patients requiring OAC undergoing PCI, TAT was associated with a lower risk of myocardial infarction but with a significantly higher risk of major bleeding when compared with DAT.

Effectiveness of Sequential Compression Devices in Prevention of Venous Thromboembolism in Medically Ill Hospitalized Patients: A Retrospective Cohort Study

Objective: To evaluate the effectiveness of sequential compression devices (SCDs) for venous thromboembolism (VTE) prevention in medically ill hospitalized patients. Materials and Methods: Adult patients admitted to a teaching hospital from April 2015 to March 2016 were included. Patients on anticoagulants with or without SCDs were excluded. We analyzed VTE risk, length of hospital stay, and other comorbidities among propensity score-matched patients on SCDs and those without thromboprophylaxis (NONE). Results: Among 30,824 patients, 67 patients (0.22%) developed VTE during their hospital stays, with deep vein thrombosis (DVT) in 55 cases and pulmonary embolism (PE) in 12. VTE was seen in 47 out of 20,018 patients on SCDs (41 DVT, 6 PE) and 20 out of 10,819 patients without SCDs (14 DVT, 6 PE). Risk-adjusted analysis showed no significant difference in VTE incidence in the SCD group compared to NONE (odds ratio 0.99, 95% confidence interval 0.57-1.73, p=0.74). Conclusion: Compared to the NONE group, SCDs are not associated with decreased VTE incidence during hospital stay.

Overutilisation of imaging studies for diagnosis of pulmonary embolism: are we following the guidelines?

OBJECTIVE: To evaluate if imaging studies such as CT pulmonary angiography (CTPA) or ventilation-perfusion (V/Q) scan are ordered according to the current guidelines for the diagnosis of pulmonary embolism (PE). METHODS: We performed a retrospective observational cohort study in all adult patients who presented to the Sparrow Hospital Emergency Department from January 2014 to December 2016 and underwent CTPA or V/Q scan. We calculated the Wells' score retrospectively, and d-dimer values were used to determine if the imaging study was justified. RESULTS: A total of 8449 patients underwent CTPA (93%) or V/Q scan (7%), among which 142 (1.7%) patients were diagnosed with PE. The Wells' criteria showed low probabilities for PE in 96 % and intermediate or high probabilities in 4 % of total patients. Modified Wells' criteria demonstrated PE unlikely in 99.6 % and PE likely in 0.4 % of total patients. D-dimer was obtained in only 37 % of patients who were unlikely to have a PE or had a low score on Wells' criteria. Despite a low or unlikely Wells' criteria score and normal d-dimer levels, 260 patients underwent imaging studies, and none were diagnosed with PE. CONCLUSION: More than 99 % of CTPA or V/Q scans were negative in our study. This suggests extraordinary overutilisation of the imaging methods. D-dimer, recommended in patients with low to moderate risk, was ordered in only one-third of patients. Much greater emphasis of current guidelines is needed to avoid inappropriate utilisation of resources without missing diagnosis of PE.

Sarcoidosis and Monoclonal Gammopathy of Undetermined Significance (MGUS): A True Association or Just a Coincidence?

Sarcoidosis is a systemic inflammatory disease characterized by the presence of noncaseating granulomas in different organs. Sarcoidosis associated with monoclonal gammopathy of undetermined significance (MGUS) is a rare finding with only 10 cases reported to date. We describe a 79-year-old male patient who presented with dry mouth for 4 months. Lip biopsy done prior to admission showed nonnecrotizing epithelioid cell granulomas. On admission, laboratory analysis was significant for elevated calcium, decreased parathyroid hormone, increased erythrocyte sedimentation rate, undetectable parathyroid hormone-related peptide (PTHrp), mildly decreased 25-hydroxyvitamin D, elevated 1,25-dihydroxyvitamin D, elevated angiotensin converting enzyme, and positive Bence Jones protein in the urine. Serum protein electrophoresis showed an elevated gamma globulin level at 38% and an IgG monoclonal gammopathy with an M-spike of 1.47. Bone marrow biopsy was consistent with MGUS. The patient showed significant improvement with steroids and was discharged with close follow-up from nephrology and oncology. Salivary gland involvement in patients with sarcoidosis is a rare finding. Our case is a valuable addition to the small number of cases described in the literature supporting an association between plasma cell disorders and sarcoidosis. Larger prospective studies are needed to determine if a true association between the two diseases exists.

Atypical Presentation of Lemierre's Syndrome Causing Septic Shock and Acute Respiratory Distress Syndrome.

Lemierre's disease is a rare but life-threatening condition characterized by an oropharyngeal infection complicating with thrombophlebitis of the internal jugular vein and disseminated abscesses. We are presenting a case of a young female who initially presented with fevers, chills, sore throat, and swollen neck later developed progressively worsening shortness of breath along with sudden onset pleuritic chest pain. She then developed progressively worsening acute hypoxic respiratory failure requiring intubation and mechanical ventilation. Interval chest X-ray showed worsening bilateral effusions. She also developed septic shock requiring pressors. Blood culture showed Fusobacterium, and antibiotics were changed accordingly following which there was a clinical improvement. The diagnosis of Lemierre's syndrome was then established based on her presenting age and bilateral pulmonary empyema in the setting of septicemia with Fusobacterium.

Role Of Conservative Management In Emphysematous Gastritis.

Emphysematous gastritis (EG) is a rare disease of the stomach that is caused by gas-forming bacteria, and it can be lethal. There have been <70 reported cases in the English literature of this disease which carries a mortality rate up to 60%. Early recognition and treatment through conservative management have been a popular and successful choice in today's medicine. Studies have shown that surgical intervention does not confer a statistical benefit on mortality in this condition. We present another case of EG in a 33-year-old woman who was successfully managed conservatively.

Atypical chronic myeloid leukemia: a rare entity with management challenges.

The aim of our study was to review the clinicopathologic features and management of atypical chronic myeloid leukemia (aCML). Relevant manuscripts published in English were searched using PubMed. aCML is diagnosed as per WHO 2016 classification in the presence of leukocytosis ≥13 × 109/l with circulating neutrophil precursors ≥10%, monocytes less than 10%, minimal basophils, hypercellular bone marrow with granulocytic proliferation and dysplasia, bone marrow blast less than 20% and absence of BCR/ABL fusion gene. Common cytogenetic features and mutations include trisomy 8, and mutations in SETBP1 and ETNK1. Median survival is 1-2 years. Hematopoietic stem cell transplant may be the only curative option. Ruxolitinib and dasatinib are emerging therapeutic options. Thus, aCML is a rare entity with poor survival. Novel therapies are needed.
