Comparative Safety and Effectiveness of Loading Doses of P2Y12 Inhibitors in Patients Undergoing Elective PCI: a Network Meta-analysis.

PURPOSE: Effective platelet inhibition prior to elective percutaneous coronary intervention (PCI) reduces the risk of ischemic complications. Newer P2Y12 inhibitors are preferred agents over clopidogrel for patients presenting with the acute coronary syndrome. However, the comparative efficacy and safety of them over clopidogrel in elective PCI is unclear. We performed a network meta-analysis to compare the safety and efficacy of loading strategies of P2Y12 inhibitors in patients undergoing elective PCI. METHODS: We conducted a systematic review of randomized controlled trials (RCT) up to June 2021 to compare the safety and effectiveness of different loading strategies of P2Y12 inhibitors before elective PCI. The endpoints of interest were overall mortality, rates of myocardial infarction (MI), stroke, revascularization, and major bleeding. Random effects model using the frequentist approach was used to perform a network meta-analysis using R software. RESULTS: Five trials with a total of 5194 patients were included in our analysis. For ischemic outcomes, including MI, stroke, and revascularization, prasugrel had the most favorable trend. However, clopidogrel had the highest probability of being most effective for major bleeding and all-cause mortality. None of these trends was statistically significant due to lack of power for each outcome. CONCLUSION: Although prasugrel and ticagrelor are known as more potent antiplatelet agents, their effects in preventing MI and stroke are marginal and do not translate into improved overall mortality and bleeding compared with clopidogrel.

Firibastat: A Novel Brain Aminopeptidase Inhibitor - A New Era of Antihypertensive therapy.

Global incidence and prevalence of hypertension continues to increase and remains a significant challenge. The ever-increasing number of cases are due to comorbid conditions such as obesity and diabetes, as well as lifestyle indiscretions such as excessive salt intake. Hypertension, congestive heart failure, and kidney disease are all conditions resulting from abnormal Renin-Angiotensin-Aldosterone activation and adverse remodeling. Firibastat, a novel Brain Aminopeptidase inhibitor, may be able to help achieve blood pressure control in those with resistant hypertension. In this review article, we will discuss the biochemical pathway of firibastat and various trials assessing drug efficacy in animals and humans. This drug has the potential to curb the risk of uncontrolled hypertension and help improve long term cardiovascular morbidity and mortality.

A rare emergence of resistance to ceftolozane/tazobactam in Klebsiella pneumoniae causing urinary tract infection.

The management of infections caused by carbapenem-resistant organisms has been a challenge. We report a rare emergence of resistance to the novel beta-lactam/ beta-lactamase combination ceftolozane/tazobactam by Klebsiella pneumoniae, causing urinary tract infection. The K. pneumoniae, in this case, was reported to be sensitive to the other novel beta-lactam/ beta-lactamase combination of ceftazidime/avibactam. The timely administration of ceftazidime/avibactam resulted in prompt clinical resolution of the urinary tract infection caused by an extensively drug-resistant K. pneumoniae.

Clinical and microbiological characteristics of patients with bacteremia and normal procalcitonin.

Procalcitonin is a biomarker of bacterial infection used to guide antimicrobial therapy. However, emerging studies have highlighted bacteremic patients with low procalcitonin, potentially limiting its clinical utility. Here, we conducted an observational, retrospective study analyzing clinical and microbiological parameters of adult patients with bacteremia and procalcitonin <2 ng/mL. High proportions of patients required intensive care (31.2%) with vasopressor (14.9%) or ventilatory (17.7%) support, developed renal injury (30.7%), or had in-hospital mortality (14.4%). When divided into subgroups by procalcitonin level, patients with procalcitonin 0.5 to 2.0 ng/mL had significantly higher rates of in-hospital mortality, vasopressor requirement, and renal injury than those with procalcitonin <0.5 ng/mL. Altogether, bacteremic patients had significant morbidity and mortality despite low procalcitonin. While subgroup analysis suggested that higher procalcitonin may correlate with illness severity, a more sensitive procalcitonin cutoff did not eliminate patients with significant disease. Procalcitonin-based algorithms may not be clinically appropriate for management of bacteremia.

Myopathy Associated With Statins and SGLT2 - A Review of Literature.

Drug-induced myopathy is a well-described clinical entity characterized by muscle damage leading to symptoms ranging from myalgias to rhabdomyolysis and acute kidney injury. Many pharmacotherapies are known to precipitate myopathic symptoms. Recent case reports suggest a potential relationship between the use of sodium/glucose cotransport 2 (SGLT2) inhibitors and onset of myopathy. The pathogenesis of this has yet to be elucidated. The relevance of this association is augmented by the recent popularity of SGLT2 inhibitors as well as the tendency for them to be prescribed alongside statins. This study reviewed the literature on the incidence and mechanism of drug-induced myopathy in patients with type 2 diabetes mellitus who are taking SGLT2 inhibitors with and without the use of statins.

Corynebacterium Jeikeium Endocarditis: A Review of the Literature.

Corynebacterium jeikeium is a gram-positive, aerobic, pleomorphic, nonspore forming bacillus, commonly present on the skin surface. Infective endocarditis secondary to C. jeikeium most commonly affects left-sided heart valves and has a higher likelihood to require valve replacement compared to other Corynebacterium endocarditis. C. jeikeium endocarditis is extremely difficult to treat as it is characteristically resistant to penicillin, cephalosporins and aminoglycosides, and sensitivity to quinolones, macrolides, tetracyclines and rifampin is variable. Despite treatment, mortality rates as high as 33% have been reported. We hereby review the literature regarding the epidemiology, diagnosis and treatment of this deadly microorganism.

Stopping the SARS-CoV-2 surge in the USA-CDC recommendations and ground realities.

As of May 10, 2020, the United States of America (USA) has 1,367,079 cases of SARS CoV-2 and 80,773 deaths associated with the disease. New York alone has more than 333,000 cases and nearly 21,271 deaths. As we are trying to reopen our economies, the biggest risk we face is a surge in the immediate cases of new infections. The second wave of infection in the fall has also been predicted. As per the Center for Disease Control and Prevention's (CDC) latest data set, among the dead from SARS COV-2 in the USA, 80% were 65 years or older. Despite lower percentages of people living in nursing homes and the fact that they represented only 11% of total cases of SARS CoV-2 cases, the maximum death rate has been seen there. A staggering 27,700 people died in long-term facilities in the USA as per the database by the New York Times. These deaths accounted for one-third of the deaths related to SARS CoV-2, making it the most intensively hurt group of al. lThe ground reality is that unfortunately, even now, most of these facilities do not have enough tests that can stop the outbreak. We suggest special targeting of residents of long-term care facilities, and the HCPs involved in these facilities to stop the spread of SARS CoV-2. Extreme measures including the highest testing numbers should be allocated to these facilities and rigorous Infection control measures should be undertaken so that the SARS-CoV-2 virus does not enter and infect the patients in these facilities and if it does, it is limited to the facility.
