The Maternal Microbiome: How Stress During Pregnancy Impacts Female Offspring in Adulthood 150 150 Tiasha Letostak, PhD

A recent study suggests a critical window of pregnancy where stress is able to influence the microbiome and intrauterine environment, with lasting behavioral consequences. Previous research has demonstrated that stress during pregnancy changes the composition of the intestinal microbiota and is related to the emergence of behavioral disorders such as anxiety and depression. A new…

Mechanism of Bacterial Adhesion to Platelets Revealed
Mechanism of Bacterial Adhesion to Platelets Revealed 150 150 Tiasha Letostak, PhD

Researchers investigate a key protein required to bind two distinct receptors on the bacteria Streptococcus oralis involved in infective endocarditis. Infective endocarditis (IE) is an infection of the endocardium, usually of the valves, and is caused by infectious agents that are typically bacterial. Understanding how these bacterial infections occur is important to the prevention, treatment…

Chromatin’s Role in Cancer Development 150 150 Tiasha Letostak, PhD

A new study investigates the role of chromatin containing the histone H3 variant in the centromere region of chromosomes in the development of cancer. Although there are many types of cancer, all cancers have one thing in common: they develop when normal processes in the body break down. Unlike normal cells, cancer cells ignore signals…

An Effective Strategy for Disrupting Bacterial Biofilms
An Effective Strategy for Disrupting Bacterial Biofilms 150 150 Tiasha Letostak, PhD

Using monoclonal antibodies to bind to proteins essential to biofilm structure and stability is highly effective against many types of bacteria that cause a variety of human disease. Biofilms are communities of bacteria that adhere to a surface and are nearly impossible to eradicate when they are pathogenic, or disease-causing. Now, a discovery from the laboratories…

Hearing Without Cochlear Nerves
Hearing Without Cochlear Nerves 150 150 Tiasha Letostak, PhD

Auditory brainstem implant devices may help young children with sensorineural hearing loss. Sensorineural hearing loss (SNHL) is the most common type of hearing loss, accounting for about 90 percent of all hearing loss worldwide. SNHL involves damage to the inner ear (cochlea) or to the nerve pathways from the inner ear to the brain, and thus cannot be managed via…

Taking a Closer Look at the Relationship Between Type 2 Diabetes and Cardiovascular Disease 1024 575 Tiasha Letostak, PhD

A new study reveals surprising results regarding vascular stiffness of coronary microvessels in the presence of type 2 diabetes. Type 2 diabetes mellitus (T2DM) is a chronic condition that affects the glucose metabolism as a result of insulin resistance. Patients with T2DM are two to four times more likely to have a heart attack than non-diabetic patients.…

Using Informatics to Help Identify Patients for Research
Using Informatics to Help Identify Patients for Research 150 150 Tiasha Letostak, PhD

Researchers use Informatics for Integrating Biology and the Bedside (i2b2), a system that can rapidly convert a large amount of clinical data into searchable information, to dramatically reduce the time needed for patient cohort identification. Patient cohort identification, or the process of finding patients with shared characteristics, is an important first step in the early…

Data-Driven Health Care Delivery
Data-Driven Health Care Delivery 150 150 Tiasha Letostak, PhD

Health care enterprise data warehouse (EDW) technology, analytics and cross-functional teams are leading to improved quality and efficiency of patient care. Big data has big potential, but despite the value of electronic health record (EHR) systems in digitizing care at hospitals, data-driven improvements are commonly hindered by an inability to measure and analyze this data…

Prodigy and Autism Share a Common Genetic Link, Study Finds 150 150 Tiasha Letostak, PhD

Researchers have discovered the first molecular genetic evidence for a shared etiology between prodigy and autism. A new study published in the journal of Human Heredity last month found that child prodigies share some of the same genetic variations with people who have autism. These findings could help geneticists better understand the molecular genetic underpinnings of autism and prodigy…

Survivors of Congenital Heart Disease Report Poor Risk Knowledge and High-Fat Diets
Survivors of Congenital Heart Disease Report Poor Risk Knowledge and High-Fat Diets 150 150 Tiasha Letostak, PhD

A new study suggests that CHD survivors may lack knowledge about their disease and would benefit from education about future risks and health behaviors. Over 1 million adults with congenital heart disease (CHD) currently reside in the United States. These individuals are at heightened risk for numerous health concerns, including endocarditis, pregnancy complications and life-threatening…

A New Take on Obesity Prevention: The Maternal-Child Relationship
A New Take on Obesity Prevention: The Maternal-Child Relationship 150 150 Tiasha Letostak, PhD

In the past 30 years, obesity has quadrupled in adolescents and more than doubled in children, affecting even preschool-aged children. The majority of childhood obesity prevention strategies focus on energy balance, targeting behaviors and environmental changes to increase physical activity, decrease sedentary behavior or limit intake of energy-dense foods and beverages. However, the limited success…

Do Your Patients Understand You? Strategies to Improve Patient-Provider Communication
Do Your Patients Understand You? Strategies to Improve Patient-Provider Communication 150 150 Tiasha Letostak, PhD

The Patient Protection and Affordable Care Act of 2010, Title V, defines health literacy as the degree to which an individual has the capacity to obtain, communicate, process and understand basic health information and services to make appropriate health decisions. However, over a third of patients in the United States — or 77 million adults…

ADHD Medications Do Not Curb Adult Height 150 150 Tiasha Letostak, PhD

According to the Centers for Disease Control and Prevention, the number of children being diagnosed with attention deficit hyperactivity disorder (ADHD) has increased from 7.8 percent to 11 percent in the last decade. Specifically, approximately 2 million more U.S. children between the ages of 4 and 17 had been diagnosed with ADHD in 2011 than in…

Sinus Infection Test Could Curb Antibiotic Overuse
Sinus Infection Test Could Curb Antibiotic Overuse 150 150 Tiasha Letostak, PhD

Antibiotic misuse, overuse and resistance have significant consequences for patients and hospitals, but determining the primary cause of sinusitis remains a clinical challenge for physicians. Now, diagnostic technology co-invented by researchers at The Ohio State University and Nationwide Children’s Hospital will better equip physicians with additional information needed to make a bacterial sinusitis diagnosis. Subinoy…

Reframing Hope in Pediatric End-of-Life Care
Reframing Hope in Pediatric End-of-Life Care 150 150 Tiasha Letostak, PhD

As physicians, you want to do more good than harm. And it is often believed that telling the truth about poor end-of-life expectations will lead to hopelessness in patients and families, causing more harm than good. But study after study on prognostication has shown that patients and their families prefer more honest and accurate communication.…
