Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Hypertensive Heart Failure: Sprinting to the Finish Line to Prevent End-Organ Damage
Hypertension affects a billion individuals globally,1 and with the aging population (79% of men and 85% of women>75 years old have high blood pressure [BP]), this number continues to grow,2,3 and the consequences of hypertension are expected to increase. High BP is second only to cigarette smoking as a preventable cause of death in the United States,4 and uncontrolled hypertension results in heart failure, coronary artery disease, kidney disease, stroke, and aortic dissection.5 Progress over the last few decades has led to better understanding and a new knowledge of this growing worldwide epidemic of high BP.

How to Keep Alzheimer ’s From Bringing About the Zombie Apocalypse
I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer. My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true. Seven years ...

Daily intermittent fasting in mice enhances morphine-induced antinociception while mitigating reward, tolerance, and constipation
The opioid epidemic has plagued the United States with high levels of abuse and poor quality of life for chronic pain patients requiring continuous use of opioids. New drug discovery efforts have been implemented to mitigate this epidemic; however, new medications are still limited by low efficacy and/or high side effect and abuse potential. Intermittent fasting (IF) has recently been shown to improve a variety of pathological states, including stroke and neuroinflammation. Numerous animal and human studies have shown the benefits of IF in these disease states, but not in pain and opioid treatment. We thus subjected male a...

Overdose Receiving Centers - An Idea Whose Time Has Come?
Authors: Hern HG, Goldstein D, Tzvieli O, Mercer M, Sporer K, Herring AA Abstract Drug overdose deaths have been the leading cause of accidental death in the United States with two thirds involving opioids. Strong evidence supports the efficacy of medications for addiction treatment such as buprenorphine and harm reduction strategies such as naloxone distribution. While emergency medical service (EMS) systems have defined specialty centers for the treatment of many significant life threatening disease (trauma, stroke, myocardial infarction) implementation of opioid use disorder systems of care that integrate EMS ar...

Antidiabetic drugs for preventing atrial fibrillation: A new revolution?
Type 2 diabetes mellitus (DM) and atrial fibrillation (AF) are 2 of the great epidemics of our time. DM affects an estimated 8.5% of adults in the United States1 and is associated with an increased risk of cardiovascular events, including AF.2 AF in turn affects up to an estimated 12.5% of adults older than 65 years in the United States, decreases quality of life, and increases the risks of heart failure, stroke, and death.3,4 In 2015, the EMPA-REG OUTCOME (BI 10773 [Empagliflozin] Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) randomized controlled trial (RCT), which assessed the sodium glucose c...

Anesthetic management for robotic hysterectomy in obese women
Purpose of review Obesity is a major health epidemic, with the prevalence reaching ∼40% in the United States in recent years. It is associated with increased risk of hypertension, diabetes, heart disease, stroke, obstructive sleep apnea (OSA), and gynecologic conditions requiring surgery. Those comorbidities, in addition to the physiologic changes associated with obesity, lead to increased risk of perioperative complications. The purpose of this review is to highlight the anesthetic considerations for robotic assisted hysterectomy in obese patients. Recent findings In the general gynecologic population, minima...

For HIV/AIDS Survivors, COVID-19 Reawakened Old Trauma —And Renewed Calls for Change
Forty years ago this month, the U.S. Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report noted a rare lung infection among five otherwise healthy gay men in Los Angeles, Calif. Though they didn’t know it at the time, the scientists had written about what would turn out to be one of the historical moments that launched the Acquired Immunodeficiency Syndrome (AIDS) epidemic. Since then, HIV/AIDS has killed an estimated 35 million people, including 534,000 people in the U.S. from 1990 to 2018 alone, according to UNAIDS, making it one of the deadliest epidemics in modern history. Over...

Epidemiologic and Genomic Analysis of the Severe Acute Respiratory Syndrome Coronavirus 2 Epidemic in the Nebraska Region of the United States, March 2020 –2021
This report details the epidemiologic and genetic evolution of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first year of the epidemic in the state of Nebraska using data collected from the Creighton Catholic Health Initiatives (CHI) health system. Statistical modelling identified age, gender, and previous history of diabetes and/or stroke as significant risk factors associated with mortality in COVID-19 patients. In parallel, the viral genomes of over 1,000 samples were sequenced. The overall rate of viral variation in the population was 0.07 mutations/day. Genetically, the first 9 months of...

Obesity and kidney transplantation
Curr Opin Organ Transplant. 2023 Feb 1. doi: 10.1097/MOT.0000000000001050. Online ahead of print.ABSTRACTPURPOSE OF REVIEW: Obesity has reached epidemic proportions in the United States. It is a risk factor for developing, among others, heart disease, stroke, type 2 diabetes, and chronic kidney disease (CKD), and thus a major public health concern and driver of healthcare costs. Although the prevalence of obesity in the CKD/end-stage kidney disease population is increasing, many obese patients are excluded from the benefit of kidney transplant based on their BMI alone. For this reason, we sought to review the experience th...
