Dr. Christiana studies the health outcomes of adults with intellectual and developmental disabilities, particularly during public health crises like the Covid-19 pandemic. His research revealed that individuals with these disabilities faced higher rates of Covid-19 infection and death compared to the general population, emphasizing the need for better protective measures. Additionally, he investigates cardiovascular treatments such as radiofrequency catheter ablation for heart rhythm issues, the use of calcium antagonists for high blood pressure, and the effects of testosterone on heart health, highlighting methods to improve patient outcomes across various medical conditions.
Key findings
Adults with intellectual and developmental disabilities in New York had higher Covid-19 case and death rates compared to the general population during the first year of the pandemic.
Radiofrequency catheter ablation successfully treats many types of fast heart rates with high effectiveness and minimal complications.
Calcium antagonists for high blood pressure showed better outcomes in Black patients and older adults than other medications.
Testosterone therapy in men with low testosterone improved total cholesterol and LDL levels but carries risks such as prostate cancer.
The Mitroflow aortic bioprosthesis had a 64% survival rate after nearly 8 years, with 75% of patients avoiding further surgeries.
Frequently asked questions
Does Dr. Christiana study Covid-19 and its effects?
Yes, he has researched how Covid-19 impacted adults with intellectual and developmental disabilities, revealing they faced greater risks than the general population.
What heart treatments has Dr. Christiana researched?
He has studied various heart treatments, including radiofrequency catheter ablation for arrhythmias and the use of testosterone for cardiovascular health.
Is Dr. Christiana's work relevant to patients with high blood pressure?
Absolutely, he has explored effective medication options for managing high blood pressure, especially in specific populations like Black individuals and older adults.
Can testosterone therapy improve heart health?
Yes, his research indicates that testosterone therapy can lower bad cholesterol levels in men with low testosterone, but it also carries potential risks.
What are the long-term outcomes of heart valve replacement surgery?
Dr. Christiana's study found that many patients with the Mitroflow aortic bioprosthesis have good long-term survival, but the valve's durability may decrease after six years.

Disability and health journal
Formica MK, Cox R, Christiana J, Turk MA, Landes SD
Plain English This study looked at how Covid-19 affected adults with intellectual and developmental disabilities (IDD) living in group homes in New York compared to the general population during the first year of the pandemic. Researchers found that people with IDD had higher Covid-19 case rates and death rates—often greater than the general population—showing that case fatality rates for people with IDD were consistently higher throughout the year. This research highlights the urgent need for better planning and support systems to protect vulnerable populations in future emergencies.
Who this helps: This helps patients with intellectual and developmental disabilities, their families, and caregivers.
Testosterone and other anabolic steroids as cardiovascular drugs.
1999
American journal of therapeutics
Shapiro J, Christiana J, Frishman WH
Plain English This research paper looks at how testosterone and anabolic steroids might be used to help people with heart diseases. It found that low testosterone levels in men can lead to higher risks of heart problems, such as high cholesterol and blood sugar levels. By giving testosterone injections to men with low levels, their total cholesterol and bad cholesterol (LDL) levels decreased, while good cholesterol (HDL) increased. However, while there is potential for benefits, there are also risks like prostate cancer, so more long-term studies are needed before recommending this treatment widely.
Who this helps: This helps men with low testosterone levels and cardiovascular issues.

Singh V, Christiana J, Frishman WH
Plain English This study looked at how calcium antagonists, a type of medication used to treat high blood pressure, can be effectively used according to new guidelines released by the Joint National Committee. The findings showed that these medications work better than others, like beta-blockers and ACE inhibitors, especially in Black patients and older adults with specific types of hypertension. This matters because using the right medication can lead to better health outcomes, reducing the risk of serious health problems.
Who this helps: This benefits patients with high blood pressure, especially Black individuals and the elderly.
Radiofrequency catheter ablation: the first decade.
1999
Heart disease (Hagerstown, Md.)
Sorbera C, Cohen M, Christiana J
Plain English This study looked at the use of radiofrequency catheter ablation (RFCA) to treat irregular heartbeats in both children and adults. It found that RFCA effectively cures many types of fast heart rates, with high success rates and few complications. This is important because it offers a minimally invasive option for patients suffering from these conditions, with the potential for more ways to treat serious heart issues in the future.
Who this helps: Patients with arrhythmias and heart conditions.
Experience with the Mitroflow aortic bioprosthesis.

Plain English The study looked at the Mitroflow aortic bioprosthesis, a type of heart valve replacement, in 168 patients with an average age of 69.7 years. It found that 64% of patients survived after almost 8 years, while 75% did not need further surgery or had valve-related issues. Additionally, the study noted that the valve functions well, but its durability starts to decrease after six years, especially in younger patients.
Who this helps: This information benefits heart patients and doctors considering valve replacement options.
