MedicalResearch.com: What is the background for this study? Would you briefly explain the symptoms/course of pilonidal disease?
Response: Pilonidal disease is relatively common and affects up to 1% of the population starting in adolescence and up until young adulthood. Pilonidal disease occurs when cysts or sinuses form between the buttocks. It is believed to be an inflammatory reaction to hair or debris that gets caught in the crease of the buttocks. Risk factors for the condition include a sedentary lifestyle, hygiene and obesity.

Response: The use of cannabis is on the rise in the United States, as it becomes increasingly legally accepted and is viewed as harmless. Furthermore, the potency of cannabis is steadily increasing over time.
There is some evidence from previous studies that compared to non-users, cannabis users require more anesthetics, have higher pain after surgery that requires more opioids, and have an increased risk of postoperative nausea and vomiting.
Given this context of increased usage and potential risks during surgery, we conducted a study to examine the impact of cannabis use on patients undergoing surgery.

Response: Several great pieces of literature already exist about patient perception of doctors wearing white coats, formal attire, business attire, and the like. But recently, scrubs are garnering favor, especially as a result of the COVID-19 pandemic.
While there has been some interest in what is worn over scrubs (jackets, vests, name tags, etc.), to our knowledge, there has not been any investigation into scrub color. Scrubs are a highly variable article of clothing, from fit, to pockets, pattern, and color, and it makes sense that these variations could have their own associated perceptions. Our study served as a way to open up the conversation around scrubs and the potential impact of their color on patients.

MedicalResearch.com: What is the background for this study?
Response: Previous research has shown that female and male physicians communicate differently with patients. Further, there is evidence that female physicians, including surgeons, spend more time with patients. This, coupled with evidence that female patients may experience disparities in the management of their pain, led us to consider that communication differences may underpin differences in surgical outcomes previously noted (eg. Wallis et al, BMJ 2017) between male and female physicians. We postulated that there may be a differential association between surgeon sex and patient sex in behaviours that would translate into clinically important outcomes.

Response: Over time, the military health system has been shifting care for its soldiers and their families away from big military treatment facilities (MTFs), allowing soldiers and their families to get care from civilian hospitals. But this has had an unintended consequence. Unfortunately, it means that military surgeons are getting fewer cases, and they are worried about maintaining their skills as surgeons. But some surgeries count more than others to help prepare the surgeon for battlefield casualties.

MedicalResearch.com: What is the background for this study?
Response: Patient cost sharing represents the portion of costs covered by insurance that individuals pay out of pocket, including deductibles, co-payment, and co-insurance. Cost sharing is increasingly common and also increasingly expensive for patients with commercial health insurance across the United States.
While designed to increase patient responsibility for health care spending, prior work has shown that higher cost sharing is also associated with decreased use of health care overall, both needed and discretionary. However, little work has been done as to how high cost sharing may affect common and costly conditions like acute appendicitis and acute diverticulitis.

Response: There is a lot of (appropriate) focus on the mortality statistics related to gun violence, but sometimes we forget about the large number of survivors of gunshot wounds. We wanted to specifically look at the long term physical and mental health outcomes in this patient population.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prominent cancer hospitals have been sharing their brands with smaller hospitals in the community. We conducted a series of nationally representative surveys and found that a significant proportion of the U.S. public assumes that the safety of care is the same at all hospitals that share the same respected brand. In an effort to determine if safety was in fact the same, we examined complex surgical procedures in the Medicare database.
We compared the chance of dying within 90 days of surgery between top-ranked hospitals, and the affiliate hospitals that share their brands. When taking into account differences in patient age, health, and type of procedure, Medicare patients were 1.4 times more likely to die after surgery at the affiliate hospitals, compared to those having surgery at the top-ranked cancer hospitals.

Response: The kidney allocation system changed in December of 2014.
The aim of the new system was to increase transplant in patients who were highly sensitized (difficult matches based on reactive antibodies) and to improve access to underserved populations.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Nonmedical prescription opioid use and prescription opioid-related overdose remain significant concerns among adolescents and young adults. Among adolescents and young adults prescribed an opioid after surgery, prior work found that 4.8% of opioid-naïve patients develop new persistent use, filling additional opioid prescriptions at 3-6 months after surgery. This work found associations of persistent use with diagnoses such as chronic pain disorders, depression, anxiety, and prior substance use disorder. It is likely that for young patients, family members may also play an important role in development of new persistent use, but this has not previously been explored. We performed this study to evaluate whether long-term opioid use among family members was associated with prescription opioid fills among adolescents and young adults perioperatively – and we found that opioid-naïve adolescents and young adults who have 1 or more family members with long-term opioid use are more likely to fill at the time of surgery, during recovery, and in the long-term with a near-doubling of rates of new persistent use.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: We performed this study because of concerns about the potential association between fluoroquinolones and aortic aneurysms and dissection raised in two large clinical studies. This concern was noted by the US Food and Drug Administration in May 2016, but the evidence was not deemed sufficient to warrant a warning. Hence, there was a clear need for additional studies to evaluate the problem. Our study was designed to determine whether there is biological evidence that ciprofloxacin—the most commonly prescribed fluoroquinolone—exacerbates aortic disease in a well-established mouse model. The model uses high-fat diet and angiotensin II infusion to stress the aorta and cause aneurysm and dissection. Using this model, we compared mice that received ciprofloxacin to control mice that received only vehicle, and we found that mice that received ciprofloxacin had significant increases in the incidence of aortic dilatation, severe aortic aneurysm and dissection, and aortic rupture and premature death. Importantly, these findings were consistent in male and female mice. Further, we investigated the potential underlying mechanisms and found that the aortas from mice that received ciprofloxacin had decreased levels of lysyl oxidase, increased levels of matrix metalloproteinases, and increased levels of apoptosis and necroptosis.

Response: Although meniscal surgeries are among the most frequently performed surgical procedures in orthopedic surgery, until just recently there were hardly any randomized trials proving its superiority over conservative treatment.
In this randomized clinical trial, including 321 patients with non-obstructive (e.g. no locking of the knee joint) meniscal tears, we found physical therapy non-inferior to arthroscopic partial meniscectomy.

Response: Firearm-related mortality is a public health issue. However, in the US, due in part to lack of funding, there is not enough research to inform the debate about firearms.
The question our group sought to answer was to understand if the presence of a semi-automatic weapon increased the number of victims killed or hurt during an active shooter incident. We chose to focus on these incidents given the availability of an FBI database detailing these active shooter incidents based on a strict definition and the similarities between such incidents that make a comparison valid.
