JAK inhibitors show promising efficacy in rheumatoid arthritis treatment

A retrospective multicenter study conducted by Japanese researchers has found that Janus kinase (JAK) inhibitors, a class of drugs used to treat rheumatoid arthritis, are highly effective. Traditionally, patients with rheumatoid arthritis have been treated with biological disease-modifying drugs, often administered through subcutaneous or intravenous routes. However, these treatments can become less effective over time.

JAK inhibitors offer a promising alternative, as they can be taken orally. Previous randomized controlled trials have demonstrated their efficacy and safety, but concerns have been raised about their real-world effectiveness, particularly in patients with additional health problems that may affect their response to conventional treatments.

Is high salt consumption linked to diabetes risk? Study sheds light

Those at risk for Type 2 diabetes may already know to avoid sugar, but new research suggests they may want to skip the salt as well.

A new study from Tulane University published in Mayo Clinic Proceedings found that frequently adding salt to foods was associated with an increased risk of developing Type 2 diabetes.

The study surveyed more than 400,000 adults registered in the UK Biobank about their salt intake. Over a median of 11.8 years of follow-up, more than 13,000 cases of Type 2 diabetes developed among participants. Compared to those who “never” or “rarely” used salt, participants who “sometimes,” “usually,” or “always” added salt had a respective 13%, 20%, and 39% higher risk of developing Type 2 diabetes.

Is Paxlovid treatment for COVID-19 effective? Study finds answers

A retrospective target trial emulation study has found that Nirmatrelvir-ritonavir treatment for COVID-19 showed limited effectiveness in preventing most post-COVID conditions (PCCs)but appeared to reduce the risk of combined thromboembolic events. The study focused on nonhospitalized veterans in VHA care who tested positive for SARS-CoV-2 during January to July 2022. The cumulative incidence of 31 potential PCCs was measured 31 to 180 days after treatment or a matched index date.

The study included 9,593 participants treated with nirmatrelvir-ritonavir and their matched untreated comparators. The results indicated no significant differences in the incidence of most PCCs between the two groups. However, participants treated with nirmatrelvir-ritonavir showed a lower combined risk for venous thromboembolism and pulmonary embolism.
