Background: Randomized clinical trials (RCTs) are fundamental to evidence-based medicine, but their real-world impact on clinical practice often remains unmonitored. Leveraging large-scale real-world data can enable systematic monitoring of RCT effects. We aimed to develop a reproducible framework using real-world data to assess how major RCTs influence medical practice, using two pivotal surgical RCTs in gynaecologic oncology as an example-the LACC (Laparoscopic Approach to Cervical Cancer) and LION (Lymphadenectomy in Ovarian Neoplasms) trials.

The private health care sector is an important source of service delivery in low- and middle-income countries (LMICs). Yet, the private sector remains fragmented, making it difficult for health system actors to support and ensure the availability of quality health care services. In global health programs, social franchising is one model used to engage and organize the private health care sector.

Article Synopsis
  • The study investigates how glycan modifications on IgG antibodies affect their role in inflammation, focusing on patients with primary Sjögren disease (SjD).
  • Researchers analyzed IgG glycosylation in 300 patients, finding lower levels of sialylation and galactosylation in those with SjD compared to asymptomatic individuals; these changes correlate with increased B cell activation and various autoantibody profiles.
  • The findings suggest that IgG Fc glycosylation could serve as a new marker for predicting disease progression, monitoring activity, and assessing lymphoma risk in SjD patients.

A better understanding of the molecular and cellular events involved in the inflammation process has opened novel perspectives in the treatment of inflammatory diseases, particularly through the development of well-designed nanomedicines. Here we describe the design of a novel class of anti-inflammatory nanomedicine (denoted as Au@MIL) synthesized through a one-pot, cost-effective and green approach by coupling a benchmark mesoporous iron(III) carboxylate metal organic framework (MOF) ( MIL-100(Fe)) and glutathionate protected gold nanoclusters ( AuSG NCs). This nano-carrier exhibits low toxicity and excellent colloidal stability combined with the high loading capacity of the glucocorticoid dexamethasone phosphate (DexP) whose pH-dependent delivery was observed.

The publication of the decree on the care of people with neurocognitive disorders brought to the fore the Reisberg's Global Deterioration Scale, a scale that only few clinicians use in memory centers or in geriatric. This scale has a number of limitations, not least of which is that it is obsolete, since it does not take into account disease advances in scientific knowledge with biomarkers. Consequently, the stages evoked no longer correspond to current descriptions.
