Article Synopsis
  • - Evidence on osteoporosis treatments like denosumab and oral bisphosphonates shows variation in effectiveness due to differing populations, clinical practices, and study methodologies, which can affect treatment outcome comparisons.
  • - This study analyzed 280,288 women over 50, comparing denosumab and oral bisphosphonates by using propensity score techniques to ensure the treatment groups were comparable before estimating treatment effects.
  • - Results indicated that achieving balance in observed covariates was generally successful after applying propensity score methods, but some residual confounding was still present, depending on the databases used and analysis methods applied.

Article Synopsis
  • A study utilized data from the French national health insurance database to analyze the effectiveness of various osteoporosis medications (denosumab, zoledronic acid, oral bisphosphonates, raloxifene, and teriparatide) on reducing fracture risk in women over 55 years old.
  • It followed five cohorts and compared fracture incidences over two years after starting treatment, highlighting a significant reduction in vertebral fractures for all medications.
  • While denosumab showed efficacy in reducing hip fracture risk and nonvertebral fractures, oral bisphosphonates displayed an increased risk for hip fractures, indicating varied effectiveness among the treatments in real-world conditions.

Kynurenine monooxygenase (KMO) blockade protects against multiple organ failure caused by acute pancreatitis (AP), but the link between KMO and systemic inflammation has eluded discovery until now. Here, we show that the KMO product 3-hydroxykynurenine primes innate immune signaling to exacerbate systemic inflammation during experimental AP. We find a tissue-specific role for KMO, where mice lacking Kmo solely in hepatocytes have elevated plasma 3-hydroxykynurenine levels that prime inflammatory gene transcription.

In this international study, we examined the incidence of hip fractures, postfracture treatment, and all-cause mortality following hip fractures, based on demographics, geography, and calendar year. We used patient-level healthcare data from 19 countries and regions to identify patients aged 50 years and older hospitalized with a hip fracture from 2005 to 2018. The age- and sex-standardized incidence rates of hip fractures, post-hip fracture treatment (defined as the proportion of patients receiving anti-osteoporosis medication with various mechanisms of action [bisphosphonates, denosumab, raloxifene, strontium ranelate, or teriparatide] following a hip fracture), and the all-cause mortality rates after hip fractures were estimated using a standardized protocol and common data model.

It is often difficult to obtain valid estimates of comparative treatment effectiveness and safety owing to differences across patient populations taking different medications in the real world. One approach for assessing comparability between treatment groups in effectiveness studies is to use negative control outcomes (NCOs). NCOs share similar sources of bias with the primary outcomes but have no plausible causal relationship to the treatment of interest.

Real world data (RWD) refers to healthcare information that is routinely collected in electronic healthcare records (EHR), hospital and pharmacy records, patient and disease registries, and health insurance databases. The collection and analysis of this vast amount of data is an important complement to that obtained from conventional randomised controlled trials (RCT). Real world data has been used for healthcare quality improvements, to conduct clinical trials, to support drug and device development, and to inform medical guidelines.

Article Synopsis
  • Penile cancer is rare, affecting about 1 out of every 100,000 males in Europe, and one-third of these cases are linked to a virus called HPV.
  • A study at University Hospital Waterford looked at 70 men with this type of cancer from 2015 to 2020 to see how many had HPV using a test called p16.
  • The results showed that 64% of the patients tested positive for p16, and those with high-risk tumors often had HPV, suggesting that boys should get vaccinated to help prevent this cancer in the future.

Unlabelled: Persistence with initial treatment was highest after 1 year, decreasing afterwards. Persistence was highest for denosumab followed by alendronate. We identified several factors associated with treatment persistence, some of which were the same irrespective of OTx agent, which could help target subgroups of patients in terms of social and healthcare support.
