When Frederick Grover, MD, former chair of the Department of Surgery and professor emeritus of cardiothoracic surgery, first landed in Nepal in November 2000, it was the people he met who made him feel like he’d found a second home. “The kindness people showed me, the welcome they gave, the warmth, was truly exceptional,” Grover recalls. “Even though that first trip wasn’t a medical visit, I could see that people would welcome us as partners in working on public health issues.”
Grover has returned to Nepal 16 times, helping to establish and grow partnerships between Nepali and University of Colorado clinicians. Grover has been involved with initiatives including the founding of the Jayanti Memorial Trust, which serves cardiac patients throughout Nepal; grant funding for cardiac initiatives through Every Heartbeat Matters; and the establishment of nutritional rehabilitation homes throughout Nepal in partnership with the Nepal Youth Foundation.

21 CU Surgeons Recognized as 5280 Magazine Top Doctors for 2022 School of Medicine
OLIVIA NEWTONJOHN DIES AFTER 30-YEAR BREAST CANCER BATTLE Greg Glasgow According to CNN, Olivia Newton-John was first diagnosed with breast cancer in 1992, after which she underwent a partial mastectomy, followed by chemotherapy and breast reconstruction. The cancer went into remission but returned in 2013 as a tumor in her shoulder. The
cancer resurfaced again in 2017 as a tumor at the base of the singer’s spine.
Denver-area magazine 5280 recently published its list of top doctors for 2022. On this year’s list, CU School of Medicine faculty members continue to be ranked among the best. We’re proud to congratulate the 193 CU School of Medicine faculty members honored with the title “Top Doctor.” The list is compiled from a survey of Denver-area physicians asking them “whom they would trust to treat themselves or a loved one” in a variety of specialty-based categories. This year, 21 surgeons in 12 specialties were recognized as Top Doctors.
That length of time between recurrences is not uncommon with breast cancer, says Nicole Christian, MD, associate professor of surgical oncology.
ARCS SCHOLARSHIP RECIPIENT Greg Glasgow ARCS Foundation, a national nonprofit dedicated to supporting academically outstanding students in science, engineering, math, technology, and medical research, has awarded a $7,500 scholarship to Anna Lee, a second-year medical student.
Lee was recognized specifically for her work in the lab of Kia Washington, MD, a professor of plastic and reconstructive surgery whose research is devoted to restoring vision through whole eye transplantation.

DOD GRANT AWARDED TO CU SURGERY FACULTY MEMBER Christene Huang, PhD, is looking for noninvasive ways to detect rejection of vascularized composite allografts.
The COVID-19 Pandemic’s Effect on Solid Organ Transplantation Surgery resident Alejandro Suarez-Pierre, MD, found a significant decline in heart, lung, liver, and kidney transplants during the first half of 2020. Greg Glasgow Solid organ transplants — heart, lung, liver, and kidney — are resourceintensive operations that require patients to take immunosuppressive drugs after the procedure to keep the body from rejecting the new organ. Add a worldwide pandemic to the mix, and the operations become even riskier and more difficult to schedule.
Greg Glasgow Soldiers and others who receive severe injuries to the hands and face often can benefit from a type of transplant known as vascularized composite allograft (VCA) — the transplantation of multiple tissues, including muscle, bone, nerve, skin, and blood vessels, as a functional unit (such as a hand or face) from a deceased donor to a recipient with a severe injury. Recipients of VCA grafts require longtime immunosuppression so their body doesn’t reject the transplant. Longtime immunosuppression presents problems of its own, however — including greater susceptibility to diseases such as cancer and infections including COVID-19 — so doctors are always
looking to balance the amount of immunosuppression a VCA recipient needs with the chances their body will reject the transplant. Christene A. Huang, PhD, a professor of plastic and reconstructive surgery and transplant surgery in the Department of Surgery, is part of a research team that recently received a grant from the U.S. Department of Defense (DOD) to study noninvasive biomarkers of VCA rejection that would allow doctors to more quickly identify potential signs of rejection and adjust immunosuppression as necessary.
“From the perspective of a transplant surgeon, you don’t want to expose your patient to COVID-19 if they are now dependent on immunosuppressants,” says Alejandro Suarez-Pierre, MD, a general surgery resident in the Department of Surgery at the University of Colorado School of Medicine. “The other perspective is, as a hospital system, can you keep admitting patients for an operation when you’re having to open five or six new intensive care units to take care of the people afflicted by the pandemic?”

However, recently published research shows that certain risk factors can indicate a more likely R-OR, allowing patients, clinicians, and family members to more comprehensively prepare for this possibility.
“What this tells us is that if possible, we should try to not match a recipient with obesity with a donor who has a history of alcohol use,” explains Hunter Moore, MD, PhD, principal investigator on the study and an assistant professor of transplant surgery.

What You Need to Know About Inguinal Hernias Paul Montero, MD, FACS, talks about symptoms, surgery, and more.
EXPLAINING PSA NUMBERS Paul Maroni, MD, explains what you need to know about PSA tests and the results. Noelle Musgrave
Greg Glasgow One of the most common surgical procedures worldwide is the repair of inguinal hernias, hernias that occur in the groin. An inguinal hernia is tissue — sometimes intestinal tissue — that bulges out of a weak spot in the abdominal wall, below the belt line. Men are far more likely than women to get inguinal hernias, and the surgery is typically a low-risk, outpatient procedure. We spoke with Paul Montero, MD, FACS, associate professor in the Department of Surgery at the University of Colorado School of Medicine, about hernias, the surgery, and when hernia belts — or trusses — are an appropriate temporary measure for pain relief. The prostate-specific antigen (PSA) is a protein produced by the prostate gland. The PSA test is a blood test used to measure the amount of this protein found in the blood. Results are reported (ng/ mL), which means nanograms of PSA per milliliter of blood. High levels of PSA have been found in men with advanced prostate cancer. “The PSA screening test helps to detect abnormalities in the blood that may indicate further testing is needed,” explains Paul Maroni, MD, associate professor of urology. According to the guidelines outlined by the American Urological

Association, shared decisionmaking for the early detection of prostate cancer is recommended for targeted groups of men with an increased risk of prostate cancer. • 55-69 years old, all men of average risk. • 40-54 years old for individuals with an immediate family member with a history of prostate cancer or Black/ African American men. Over the age of 70, men should have a discussion with their doctor about whether PSA testing makes sense for them.

Research Shows Low Patient Comprehension of Cancer Terms Rachel Sauer
LIVING-DONOR LIVER TRANSPLANT RECIPIENTS GAIN LIFE-YEARS New research shows that more inclusive criteria for liver transplant eligibility allow for significant gains for more patients. Rachel Sauer Research recently published in JAMA Surgery demonstrates that living-donor liver transplant (LDLT) recipients gain an additional 13 to 17 life-years following their surgery compared with patients who remain on the donor waitlist. This research also pushes back against long-held standards that patients in need of a liver transplant should have a Model for End-stage Liver Disease incorporating sodium levels (MELD-Na) score of at least 15 to be considered for transplant. Researchers found that patients with MELD-Na scores as low as 11 had a
34% decrease in mortality compared with those who remained on the waitlist. “The really staggering part of the study was that we determined that the survival benefit is not something that increased by several months or even a year or two. The benefit that the patient can expect to gain is 13 years or more,” says Elizabeth Pomfret, MD, PhD, chief of transplant surgery in the University of Colorado School of Medicine and the senior author of the study.
Alexandra Verosky, a third-year medical student and her coresearchers, including research mentor Sarah Tevis, MD, assistant professor of surgical oncology, designed a survey to assess patient understanding of eight terms common in breast pathology reports: malignant, benign, metastatic, neoplasm, negative, mass, carcinoma, and high grade. Here are the definitions for eight common cancer terms. How well do you comprehend them? Mass: An abnormal collection of tissue or cells that may or may not be cancerous. High Grade: A term used to describe cells that look abnormal under a microscope. Benign: Not cancerous/nonmalignant. Malignant: Cancerous; abnormal cells that can invade and destroy normal tissue or spread to other parts of the body. Negative: The abnormality being looked for is not found/ not present. Neoplasm: New growth/ abnormal growth which may or may not be cancer/tumor. Carcinoma: Cancer originating from the lining layer (epithelial cells) of organs (or skin). Metastatic: Cancer that has spread from the primary (original) site to other structures or organs.

TELEHEALTH FOLLOW-UP AFTER GALL BLADDER SURGERY IS AS EFFECTIVE AS IN-PERSON CLINIC VISITS Greg Glasgow
Surgical resident Danielle Abbitt, MD, says the findings will help eliminate barriers to care. A new research study by Danielle Abbitt, MD, a resident in the University of Colorado Department of Surgery, shows that a protocol that started as a necessity during the COVID-19 pandemic has evolved into a timesaving step for patients recovering from surgery. Abbitt’s paper, published in August in the journal Surgical Endoscopy, shows that a telehealth appointment to follow up after a cholecystectomy (gall bladder removal), is just as effective as an in-clinic visit to detect and address postoperative complications including wound infections and cardiopulmonary complications such as pneumonia and pulmonary embolism. The
retrospective review was conducted on patients receiving care at the Rocky Mountain Regional VA Medical Center on the CU Anschutz Medical Campus. “Based on my clinical experience seeing patients, my hunch was that the results would be similar between telehealth and a clinic visit,” says Abbitt, who also conducted a similar study on patients who undergo surgery to repair an inguinal hernia.
RECOGNIZING & PREVENTING PERIPHERAL ARTERY DISEASE Greg Glasgow
That pain when you walk could be more serious than you think. It could be a sign of peripheral artery disease (PAD), a condition in which a narrowing of the arteries results in reduced blood flow to the arms or legs. When the arms or legs — PAD typically affects the legs — don’t receive enough blood flow to keep up with demand, it can cause pain when walking and other symptoms. PAD is usually a sign of a buildup of fatty deposits in the arteries, known
as atherosclerosis. Atherosclerosis is the most common cause of PAD, says Max Wohlauer, MD, associate professor of vascular surgery. Atherosclerosis is a hardening of the arteries due to a buildup of plaque. Atherosclerosis-related diseases are the leading cause of death in the United States.

Period of Transition Teams and initiatives in the CU School of Medicine take on the challenges of pediatric-toadult transition of care Greg Glasgow For children with pediatric-onset chronic conditions, the relationships they form early on with their doctors and care team members often turn out to be among the most important connections of their young lives. Years later, when those youth are on the cusp of adulthood and required to transition to adult care, the doctor-patient relationship becomes even more important, and thoughtful transition of care is critical. The growing field of transitional care encourages collaboration among doctors to help young patients effectively manage the shift from pediatric to adult care, to encourage those patients to play a greater part in their own health care, and to improve health care systems to make those transitions more seamless. It’s an area of growing importance at the University of Colorado School of Medicine, where several new initiatives are aimed at creating pathways and procedures to help young patients through one of the most important medical transitions of their lives.
WHY OLDER LUNGS DON’T RESPOND WELL TO TRAUMA Research completed at the University of Colorado Department of Surgery found that advanced age affects immune cells in the lungs. Greg Glasgow
Why are older people at higher risk for lung injury, especially after trauma? The answer may lie in the macrophages, the immune cells that live in the air spaces of the lungs. As a student at the University of Colorado School of Medicine, Devin M. Boe, MD, PhD — now a resident at Georgetown University School of Medicine — conducted research showing that aging impacts macrophages in the lung, causing them to be unable to work as effectively when the body is subjected to trauma. His paper was published in September in the Journal of Leukocyte Biology.

“The elderly are at much higher risk of lung infections and lung disease in general; we know that the immune system of the lungs gets 12

Thoracic Surgeons Launch Enhanced Recovery Plan for Patients Greg Glasgow
PAIN IN PEDIATRIC PATIENTS UNDERGOING SURGICAL STENT REMOVAL Kyle Rove, MD, found insignificant difference in pain levels between children who received ibuprofen before stent removal and those who received a placebo. Rachel Sauer In a study published in the Journal of Pediatric Urology, researchers found that following a surgical ureteral stent removal procedure, children who had been given ibuprofen before the procedure did not report lower levels of pain in the 24 hours afterward than children who had received a placebo before the stent removal. “There are still a lot of unknowns about using ureteral stents in pediatric patients, and one is just pain control in general,” explains study principal investigator Kyle Rove, MD, assistant professor of urology in the
University of Colorado Department of Surgery. “Though our hypothesis was rejected, we learned a lot about how to conduct a randomized control trial in a pediatric surgical population, which is not very common in research, and we got a clearer picture of how much research needs to be done on minimizing or preventing surgical patient pain or discomfort in pediatric patients.”
A new enhanced recovery protocol for patients undergoing lung resection surgery performed by faculty members in the University of Colorado Department of Surgery is resulting in patients going home sooner, experiencing less postoperative pain and complications, and taking fewer opioid drugs to manage their pain. “Patients having surgery are prone to complications after surgery, and over the past decade or so, there has been a significant effort nationally and internationally to identify and streamline patient processes of care to try and minimize complications,” says Robert Meguid, MD, MPH, professor of cardiothoracic surgery in the CU School of Medicine, who designed the protocol with general surgery research resident Adam Dyas, MD. “These are efforts to develop streamlined protocols that apply to patients from when we first meet them in clinic through to their surgical encounter, all the way to their recovery,” Meguid says. “We are applying techniques that have been shown to decrease postoperative complications, such as wound infections, shorten length of stay, and improve quality-of-life outcomes and recovery from surgery.”
We studied one specific aspect of ureteral stents, which is during the time of removal, but sometimes patients need stents anywhere from one to 12 weeks. 13

STUDY HAS POTENTIAL TO IMPROVE EDUCATION AND TREATMENT OF SEXUAL HEALTH FOR BREAST CANCER PATIENTS CU Anschutz researchers find patients would like better education and counseling about how treatment can negatively impact their sexual health Laura Kelley
A new study released by the University of Colorado Cancer Center shows that more than 70% of breast cancer patients have reported changes that affect their sexual health during and beyond treatment. “More than 3.8 million breast cancer survivors live with permanent or temporary physical and psychological consequences of treatment that impact their sexual health. However, there is limited data that advises providers on the preferred format and timing of sexual health education,” said Sarah Tevis, MD, assistant professor of surgical oncology at the University of Colorado School of Medicine Campus.
The study, published in the Annals of Surgical Oncology, mentions that most oncology teams don’t discuss many of the potential sexual health effects of breast cancer treatment with patients. “Patients we spoke with in focus groups all reported sexual side effects they were not prepared for during treatment. However, all expressed the desire to have those effects addressed early in the diagnosis and would like counseling to be available from the medical team,” Tevis says.
