Researchers at the Mayo Clinic have found ways that the sex and age of an individual can play a large part in who experiences a heart attack, the methods used to treat these heart attacks, and the eventual post hospital outcomes of the people who experience heart attacks, according to a press release.
The objective of this study was to determine whether age is a key factor in sex-related differences among patients who experienced a heart attack. Using public all-payer hospitalization data from the Nationwide Inpatient Sample, the research team evaluated more than 6.7 million hospitalization records for heart attacks. The researchers then categorized the information by sex and divided the patients into 4 age categories: under 45 years of age, 45 to 64 years of age, 65 to 84 years of age, and over 84 years of age. …

Patients with mantle cell lymphoma (MCL) and primary gastrointestinal (GI) involvement have similar outcomes to those with secondary GI involvement, according to results from one of the largest known studies of GI MCL that was published in Blood Cancer Journal.
“The main implications of our research are that primary GI MCL is a rare and distinct presentation of MCL and it tends to be treated less aggressively, especially in patients with a lesser extent of GI involvement. However, we showed that it has a similar outcome to that of secondary GI MCL. Therefore, we can conclude that less aggressive treatment of primary GI MCL could be reasonable, even if it is still unknown how an intensified systematic treatment approach for these patients could result in better outcome,” Grzegorz S Nowakowski, MD, told Targeted Oncology, in an interview. …

Lupus rates are 9 times higher in women than men, and are highest among American Indian and Black women, according to new data.
The research provides the first national estimate of how widespread the auto-immune disease is, including its prevalence in certain ethnic groups. Overall, a total of 204,295 people had lupus in 2018 in the United States, according to the study published this month in the journal Arthritis & Rheumatology. … The more comprehensive data on lupus rates in the United States will improve research efforts, too, says Ali Duarte Garcia, MD, a rheumatologist at Mayo Clinic who was not involved in this latest research, but is a recent recipient of CDC funding to carry this lupus research forward.
“Now we can look closer at patients’ experiences with lupus and how the disease evolves,” Dr. Duarte Garcia says.
His ongoing work with the CDC will consider lupus patients’ access to healthcare, pain management, the prevalence of disability, the severity of the disease, and mortality and survival rates based on the data from these registries.

R regular exercise comes with plenty of perks — from feeling more connected to your body to the euphoria of runner’s high (it’s real, we promise). It can even reduce your chances of having a headache or migraine. But, it can also have the opposite effect and cause a whopper of a head banger, too. While experts aren’t completely sure what causes them, some of us tend to be more susceptible.
“They are more common in individuals who also experience migraines,” says Rashmi B. Halker Singh, MD FAHS, headache neurologist at Mayo Clinic. In a study published in Headache: The Journal of Head and Face Pain, women disproportionately experienced more migraines than men. …

New research from a Mayo Clinic-led team of physicians found the initiation of pain medication for newly diagnosed diabetic peripheral neuropathy has dropped by more than a third since 2014, but also found rates of opioid prescribing remain high. …
New findings of breast cancer gene mutations in women who have no family history of the disease offer a new way of estimating risk and may change the way in which these women are advised on risk management.
The findings come from two large studies, both published on January 20 in The New England Journal of Medicine.
A nationwide panel of experts has developed the first mammography guidelines for older survivors of breast cancer, providing a framework for discussions between survivors and their physicians on the pros and cons of screening in survivors’ later years.
The guidelines, published online today in a paper in JAMA Oncology, recommend discontinuing routine mammograms for survivors with a life expectancy under five years; considering stopping screening for those with a 5-10-year life expectancy; and continuing mammography for those whose life expectancy is greater than 10 years. The guidelines will be complemented by printed materials to help survivors gauge their risk of cancer recurring in the breast and weigh the potential benefits and drawbacks of mammography with their health care team.

Iowa Sen. Chuck Grassley blames escalating insulin prices on manufacturers, health plans, and practices that give vendors discounted prices. PolitiFact Iowa found that to be true. …
Some insulin producers blame insulin’s prices on the cost of innovation. However, Mayo Clinic hematologist S. Vincent Rajkumar dismissed this claim in a paper published by Mayo Clinic in January 2020. Rajkumar wrote that limited innovation exists when it comes to insulin, and that what matters more is affordability. This sentiment was echoed in the April 2019 House hearing when Rep. Mckinley (R-West Virginia) said, “Innovation is supposed to drive prices down, not up.” …

… While a diet rich in unsaturated fats might exacerbate certain illnesses, scientists say eating saturated fats could help protect against them. The findings could offer the answer as to why obesity seems to have a positive impact during acute or short term illness.
Study authors say one example is acute pancreatitis (AP). Diets rich in unsaturated fat may worsen the condition however, saturated fats may provide protection. People with the illness suffer from inflammation of the pancreas, with stomach pain being the main symptom.
“Obesity sometimes seems protective in disease,” the team, led by corresponding author Vijay Singh, writes in the journal Science Advances. “This obesity paradox is predominantly described in reports from the Western Hemisphere during acute illnesses.” …

Higher fiber intake may be associated with decreased risk of depression in premenopausal women, new research suggests.
Investigators analyzed data from close to 6000 pre- and postmenopausal women. They found that, in premenopausal women, dietary fiber intake was higher among those without depression vs their counterparts with the disorder in a dose-dependent manner. However, there appeared to be no relationship between higher fiber intake and depression risk in postmenopausal women.
… Commenting on the study for Medscape Medical News, Stephanie S. Faubion, MD, MBA, a professor and chair of the Department of Medicine and the Penny and Bill George director of the Mayo Clinic's Center for Women's Health in Rochester, Minnesota, noted the study was cross-sectional and therefore the direction of the association could not be determined and "causality cannot be assumed." …

Even after a decade of treating patients with hematologic malignancies with chimeric antigen receptor (CAR) T-cell (CAR-T) therapies, researchers are still trying to understand why most patients eventually relapse. Equally puzzling to some scientists is the question of these cellular interventions cause lasting remission at all in many patients. …
A study published by Brody’s team and collaborators at Kite Pharma in Cancer Discovery in December 2020 offered one explanation.4 Experiments in animal models suggested that CAR-T cells can kill off-target cells that are in the vicinity of the cells they’re designed to target, offering the first in vivo proof of localized bystander killing. This off-target effect is mediated by the interaction between the protein Fas—a cell death receptor expressed on many cellular surfaces—and its ligand, which is present on T cells. In fact, tumoral expression of Fas was predictive of survival in patients with DLBCL who were treated with anti-CD19 CAR-T cell therapy in the phase 1/2 ZUMA-1 trial (ClinicalTrials.gov identifier: NCT02348216). …
“I think it’s becoming more and more [clear] that the CAR-Ts, in addition to their CAR interaction with the tumor antigen, rely on the Fas-Fas ligand…interaction to exert their killing. The next question is, ‘how do we manipulate these pathways safely to make CARs more potent?”” said Saad J. Kenderian, MB, ChB, a consultant in the division of hematology in the department of internal medicine at the Mayo Clinic in Rochester, Minnesota, who was not involved in the study. …

Driftless JOURNAL (Decorah, Iowa), 1/30/2021
… Scott Bohner, D.O., Mayo Clinic Health System family medicine physician at Winneshiek Medical Center in Decorah, noted that the onset of symptoms may occur minutes or hours after suffering a concussion, such as confusion, headache, dizziness, nausea or fatigue. Other symptoms, which include memory issues, difficulty sleeping, mood changes and imbalance, can arise days later.
Individuals should seek medical care if they suspect a concussion and are experiencing a severe headache, trouble walking or talking, vision changes, vomiting more than three times, loss of control over bladder or bowels, or feeling weak or numb in part of the body.
“Obviously the more physical or dangerous the sport is to the head, the more risk of concussion,” the WMC doctor said.
