A University of Rochester researcher will be leading a new study on the effects of smoking tobacco and electronic (e)-cigarettes.
Dr. Sherry L. Spinelli, Ph.D. is a research associate professor in the Department of Pathology and Laboratory Medicine at University of Rochester Medical Center. She is principal investigator in a study funded by the world's leading tobacco company, Phillip Morris International.
The study will analyze health data from current and former smokers, as well as people who use e-cigarettes and those have never smoked. Philip Morris will use the information to develop reduced-risk products (RRPs), or products that are less harmful than tobacco cigarettes.
While that may seem counterproductive to promoting good health, Spinelli says it's crucial to collect a broad sample of information on the biological effects of smoke on blood platelets and the entire vascular cell population to understand how smoking promotes cardiovascular disease, cancer and chronic obstructive pulmonary disease. This means comparing the health of smokers and nonsmokers alike.
"Everybody knows smoking is a major health risk and the best thing to do is not start or to quit if you are a smoker," she said. "That's not always realistic because smoking cessation is very difficult for a high percentage of individuals and despite prevention programs and health warnings, young people are still developing bad habits when it comes to smoking and the increasing use of new tobacco products. In addition to prevention programs, we are very interested in minimizing harm, which is a major objective of the FDA and other world health organizations."
The study is now underway and is scheduled to continue through fall of 2017.
Behind many patient diagnoses is a process that starts in the operating room and ends under a microscope.
UR Medicine Labs has a team of histotechnicians (HT) and histotechnologists (HLT), often referred to as "histotechs," who work around the clock to complete the steps leading up to patient diagnoses for cancer and other diseases.
Histotechs are responsible for taking human tissue to prep, cut, and stain before it's examined by a pathologist. We recognize this important work in honor of Histotechnology Professionals' Day on Thursday, March 10.
"I think most people have never heard of histology," said histotech Wally Pryjmak, who has worked at UR Medicine Labs for two years. He didn't even know what a histologist was when he became a certified medical lab technician. Nevertheless, Pryjmak wants patients to understand the link between his work and their treatment. As he says, "We create the slides your diagnosis is based on, so without us it would be a lot harder to get diagnosed."
The tissue prep process starts after a patient has surgery to remove tissue from the body, often in a biopsy. This tissue is brought to the Surgical Pathology area (located on the ground floor of SMH) and is most often examined first by a pathologist's assistant (PA) who dissects the tissue at a grossing station.
The tissue sample then goes into the hands of a histologist who processes it through a series of alcohols to remove any water, clears tissue in xylene and infiltrates it in paraffin wax. The tissue is then embedded into a paraffin block and the histologist cuts it into paper-thin slices.
Wax slices of tissue then go into a warm water bath to stretch them out and prevent wrinkles before carefully placing the tissue onto a glass microscope slide. The histologist gently scoops the section of tissue onto the slide to dry. He or she then treats the slide with a basic stain (hematoxylin and eosin) to make the sample is easy to see under the lens.
There are up to 75 different stains that reveal certain tissue elements, fungus, or bacteria. A pathologist can request any combination of stains be added before viewing the slide close-up.
In this way, the histologist is part artist and part chef: they must follow a "recipe" of stains to yield a proper reading. Even a small misstep can compromise the diagnosis. Once the slide is treated with the proper stains, it goes to a pathologist who examines it and issues the diagnosis.
The work of a histologist requires careful attention to detail and physical stamina. On average, the histology team at Strong prepares between 800 and 1,200 slides each day.
Diana Scott is the supervisor for histopathology at Strong. To her, the work of a histologist is like an art form. And while patients don't see or speak with the lab team helping behind the scenes, the connection is still very meaningful.
"We care about the production side of things and the quality of the slides," said Scott. "We treat every specimen like it belongs to one of our family members waiting for their test results to come back."

(Above right) There are more than 75 special stains used to dye tissues so they can be viewed clearly under a microscope. The stains highlight specific tissue components (nuclei, muscle, etc.) or microorganisms (bacteria, fungus) and a combination of stains is often necessary.
(Right) Tissue blocks, or cassettes, are preserved and filed for at least 20 years after a diagnosis is given.
This year, the Department of Pathology and Lab Medicine is benefiting from donations provided by Friends of Strong, a volunteer organization that supports Strong Memorial Hospital through fundraising.
In 2015, FOS allocated a total of $110,004 to Pathology. These funds were used to purchase lab equipment including a triple headed microscope, four centrifuges, a spectrophotometer, a tissue cassette printer and gel photography system.
"The Department of Pathology and Laboratory Medicine is both thankful and gratified at the generous contributions from the Friends of Strong," said Dr. Bruce Smoller, department chair. "So often, a supporting department such as ours, and its needs fall beneath the radar screens of well-meaning organizations and individuals and we are genuinely delighted that the Friends of Strong recognize the manifold important functions of our department."
Friends of Strong is supported by proceeds from Friends of Gift Shop, Finger Lakes Coffee Roasters, the Specialty Shop, and Baby Prints Photography at Strong Memorial Hospital.

In February, Pathology residents celebrated the opening of a new and improved study room.
Renovations to the space included new cubicle walls, carpet and a fresh paint job.
The room, which serves as a meeting place and quiet study area, is located on the second floor at 2-6440.
It was previously home to cytopathology, whose office moved to 2-2100 in 1997.
