Growth plates (GP), situated at the ends of long bones in children, supply chondrocytes necessary for bone growth. Damage to the growth plate due to fractures often results in arrested bone growth, making it a significant cause of skeletal disorders in children. However, a small percentage of these injuries astonishingly manage to heal themselves, a phenomenon that had remained a mystery until now. In a new study published in International Journal of Oral Science, Yao Sun from Tongji University and other researchers identified that primary cilia, cellular ...

Bare minimum reimbursement rates could be a factor in why some clinics may be struggling to offer HPV vaccination in the U.S. MUSC Hollings Cancer Center researcher Kalyani Sonawane, Ph.D., and a team of researchers from South Carolina and Texas decided to quantify private insurance reimbursement rates for the HPV vaccine after several qualitative studies noted that health care providers were dissatisfied with HPV vaccine reimbursement by private insurance companies. The results of their investigation were published July 24 in the Annals of Family Medicine. They found that ...

In a new study published in the Proceedings of the National Academy of Sciences, authors Gabriel Gellner and Kevin McCann from the University of Guelph and SFI External Professor Alan Hastings (UC Davis) invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors’ novel inverse method assumes the ecosystems exist and works backward to characterize food webs that support that assumption. Their work represents a significant step toward addressing a fundamental ecological question of how biodiversity ...

Most navigation apps can show you the fastest possible route to your destination and some can even suggest an eco-friendly route calculated to produce the least amount of carbon emissions. But what if they could also map the safest route with the lowest possible risk of a crash? A new algorithm developed by UBC researchers could make this a reality. Led by Dr. Tarek Sayed, professor in the UBC department of civil engineering, and PhD student Tarek Ghoul, the group developed a new approach ...

Researchers from Tokyo Medical and Dental University (TMDU) identify a promising way to improve bone repair with important clinical applications Tokyo, Japan – Although bones have the ability to regenerate and repair themselves, they are generally unable to do so when the injury is larger than a small break or chip. In a study just published in Inflammation and Regeneration, Japanese researchers have developed a technique for improving bone regeneration over large areas in rats—and their findings may translate well to clinical settings. As most of us know from experience, bones can repair themselves after a minor break ...

French researchers conducted a large, simulated study to examine the relationship between the presence of primary care physicians (PCPs) and the ability of patients to register with a PCP. The study aimed to analyze local PCP supply based on various indicators, including PCP presence, patient registration availability for office visits, and patient registration availability for home visits. Out of 5,188 census blocks, 55.4% had at least one PCP, with 38.6% of those blocks allowing registration for office visits and 19.46% allowing registration for home ...

Researchers from the Netherlands conducted an observational study to determine the association between personal continuity and potentially inappropriate prescriptions (PIPs) by family physicians in older patients. PIPs can be categorized as potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs). The study utilized anonymized routine care data from 269,478 patients, receiving care in 48 Dutch family practices, from 2013 to 2018. They included all patients 65 and older with five or more contacts with their practice in six years, giving them a sample of 25,854 individuals. ...

Researchers from Mathematica studied high-performing Comprehensive Primary Care Plus (CPC+) sites to identify key strategies that contributed to significant reductions in acute hospitalization rates. Researchers identified CPC+ practice sites with the highest likelihood of achieving substantial reductions in Medicare acute hospitalization rates between 2016 and 2018, and referred to them as "Acute Hospitalization Rate (AHR) high-performers." Afterwards, they conducted telephone interviews and within- and cross-case comparative analyses of 14 of these primary care practice sites, ...

Researchers explored how primary care physicians who have some familiarity with medications for alcohol use disorder (MAUD) make prescribing decisions and identify reasons for the underuse of MAUD in primary care. They interviewed 19 primary care physicians who had recently prescribed MAUD to patients in an outpatient setting. These physicians were selected from a large online database of medical professionals. Participating physicians reported several challenges in prescribing MAUD: (1) they had somewhat negative personal beliefs about the effectiveness of medications and the likelihood of patient ...

Human papillomavirus (HPV) vaccination coverage has improved in the United States, but privately insured adolescents have lower initiation and completion rates compared to those under public insurance programs. One of the contributing factors to this disparity is the higher cost of the HPV vaccine compared to other routinely recommended adolescent vaccines. While private payers typically reimburse the cost of the HPV vaccine at or above the CDC list price (i.e., $210.99 in 2017-2018), it remains below ...
