(Press-News.org) People who use methamphetamine are more likely to have health conditions, mental illness, and substance use disorders than people who do not use the drug, according to a new study by researchers at the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU School of Global Public Health. The findings are published in the Journal of General Internal Medicine.
The use of methamphetamine--a highly addictive and illegal stimulant drug--has increased in recent years, as have overdose deaths. Methamphetamine can be toxic for multiple organs including the heart, lungs, liver, and neurological system, and injecting the drug can increase one's risk for infectious diseases.
"Methamphetamine can complicate the management of existing chronic illnesses, but we know little about the chronic disease profile of people who use it," said study author Benjamin Han, MD, a clinician-researcher in the Division of Geriatrics, Gerontology, and Palliative Care in the Department of Medicine at the University of California San Diego.
Using data from the 2015-2019 National Survey on Drug Use and Health, a nationally representative survey of U.S. adults, the researchers estimated the prevalence of medical conditions, mental illnesses, and other substance use among those who reported using methamphetamine within the past year.
Compared to adults who do not use the drug, people who use methamphetamine were nearly twice as likely to have medical multimorbidity (two or more chronic medical conditions), more than three times as likely to have mental illness, and more than four times as likely to have a substance use disorder. Many have a combination of medical, mental, and substance use issues, including all three concurrently.
Of the chronic illnesses studied, people using methamphetamine had a higher prevalence of liver disease (hepatitis or cirrhosis), lung disease (COPD or asthma), and HIV/AIDS. The researchers also found that those using methamphetamine had a considerably higher likelihood of substance use disorders for all drugs studied, including heroin, prescription stimulants, prescription opioids, cocaine, and sedatives.
"Our results certainly do not suggest that meth use causes most of these conditions, but they should inform clinicians that this population is at risk. Future studies are needed to determine how dose and frequency of use relate to these conditions--for instance, occasional use on a night out versus chronic use that can lead to a host of adverse effects on the body," said study author Joseph Palamar, PhD, an associate professor of population health at NYU Grossman School of Medicine and a CDUHR researcher. "We also confirmed the well-known link between meth use and HIV, which can result from injection drug use or sexual transmission, but more research is needed to determine the extent to which meth use increases risk for STDs due to the drug's libido-enhancing effects."
The researchers note the importance of a harm reduction and patient-centered approach to care for people who use methamphetamines, and one that can coordinate management of mental illness, medical disease, and substance use disorders.
"Methamphetamine use adds complexity to the already-challenging care of adults who have multiple chronic conditions," added Han, who is also a CDUHR researcher. "Integrated interventions that can address the multiple conditions people are living with, along with associated social risks, are needed for this population."

A new study in the journal Sleep finds that increased evening screen time during the Covid-19 lockdown negatively affects sleep quality.
During the lockdown period in Italy, daily internet traffic volume almost doubled compared to the same time in the previous year. Researchers here conducted a web-based survey of 2,123 Italian residents during the third and seventh week of Italy's first national lockdown. The survey ran in the third week of lockdown (March 25th - 28th, 2020) and evaluated sleep quality and insomnia symptoms, using the Pittsburgh Sleep ...
A study published in the journal Pediatrics shows the combination of two early reading programs had positive effects on preschool students entering kindergarten in Cincinnati Public Schools over a three-year period.
The two early reading programs are: Reach Out and Read, through which children receive a new book and guidance about reading at home during well-visits from newborn through age 5; and Dolly Parton's Imagination Library, which mails new books to the child's home once a month from birth through age 5. Each of these is well-established at Cincinnati Children's Hospital Medical Center and across the nation.
"With this early study, we suggest that when combined and sustained, ...
CHAMPAIGN, Ill. -- Many species of ground-dwelling beetles, ladybugs, hoverflies, damsel bugs, spiders and parasitic wasps kill and eat pest species that routinely plague farmers, including aphids and corn rootworm larvae and adults. But the beneficial arthropods that live in or near cropped lands also are susceptible to insecticides and other farming practices that erase biodiversity on the landscape.
A new study reveals that beneficial arthropods are nearly twice as abundant and diverse in uncultivated field edges in the spring as they are in areas that ...
A University of Birmingham-led study of over a thousand dental professionals has shown their increased occupational risk of SARS-CoV-2 infection during the first wave of the pandemic in the UK.
The observational cohort study, published today (3 June 2021), in the Journal of Dental Research, involved 1,507 Midland dental care practitioners. Blood samples were taken from the cohort at the start of the study in June 2020 to measure their levels of antibodies against SARS-CoV-2, the virus that causes COVID-19.
The team found 16.3% of study participants - which included dentists, dental nurses and dental hygienists - had SARS-CoV-2 antibodies, compared to just 6% of the general population at the time. Meanwhile, the percentage of dental ...
Scientific papers suggesting that smokers are less likely to fall ill with covid-19 are being discredited as links to the tobacco industry, reveals an investigation by The BMJ today.
Journalists Stéphane Horel and Ties Keyzer report on undisclosed financial links between certain scientific authors and the tobacco and e-cigarette industry in a number of covid research papers.
In April 2020, two French studies (shared as preprints before formal peer review) suggested that nicotine might have a protective effect against covid-19 - dubbed the "nicotine hypothesis."
The stories made headlines worldwide ...
New York, NY (June 2, 2021) - A phase 3 clinical trial co-led by Mount Sinai researchers is the first to show that immunotherapy after surgery to remove bladder cancer can reduce the risk of relapse for patients who are at high risk of their cancer returning in a deadly metastatic form, according to results published in The New England Journal of Medicine. The immunotherapy nivolumab was used as an adjuvant therapy, which is given after surgery in the hopes of maximizing its effectiveness.
The randomized trial, named "Checkmate 274," showed that using nivolumab increased these patients' chance of staying cancer free after surgery compared to patients who received a placebo. The average length of time before relapse nearly doubled ...
June 5, 2021 marks the 40th anniversary of the first report of AIDS cases and the onset of the American AIDS epidemic. In a new, thought-provoking paper in the New England Journal of Medicine, Professor Ronald Bayer and co-author Gerald Oppenheiner capture the experiences of the physicians who were central to the AIDS epidemic. In the words of the doctors, they relay what it meant to look back after 40 years and how they "aged together."
The doctors called their experiences extraordinary and the conditions demanding, under which they performed their duties and treated their patients. They speak of their work as "in the trenches," giving their careers immediate meaning and value that they never expected. As several physicians expressed, ...
MINNEAPOLIS - Deep brain stimulation continues to be effective in people with Parkinson's disease 15 years after the device is implanted, according to a study published in the June 2, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers found that compared to before deep brain stimulation, study participants continued to experience significant improvement in motor symptoms, which are symptoms that affect movement, as well as a reduction in medications 15 years later.
Parkinson's disease can progressively affect speech, walking and balance due to a gradual reduction of a chemical in the brain called dopamine. Parkinson's symptoms of muscle stiffness, tremor and slowness ...
MINNEAPOLIS - Older people with type 1 diabetes who have been to the hospital at some point for both low and high blood sugar levels may be at six times greater risk for developing dementia years later. The research is published in the June 2, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found that people with type 1 diabetes who visit the hospital for just one of the blood sugar extremes may also be at greater risk for developing dementia.
Type 1 diabetes is a chronic condition in which the pancreas produces little or no insulin.
Hypoglycemia is low blood glucose, or the main sugar in blood, that may result in loss of consciousness. Hyperglycemia results from insulin deficiency or extremely ...
URBANA, Ill. -When pigs get hit with significant illnesses during key stages of pregnancy, their immune response may negatively affect developing piglets, making them less productive on the farm. New research from the University of Illinois shows that when those piglets - especially males - experience a second stressor in early life, they are at higher risk of neurodevelopmental and other neurological anomalies, putting them at an even greater disadvantage in production settings.
"With more information about maternal illness, what we call maternal immune activation, we can make better decisions about how to handle these types of immune challenges within animal production settings," says Marissa Keever-Keigher, doctoral student ...
