Article Synopsis
  • Aging increases the risk of cancer by affecting how the immune system works, especially in lung tumors.
  • Older immune cells lead to the buildup of certain cells that produce IL-1⍺, which makes cancer grow faster.
  • By blocking IL-1R1 signaling early on, scientists found they could slow down cancer growth in the lungs, colon, and pancreas, and learned how aging is linked to worse cancer outcomes in humans.

In the primary care setting providers have more tools available than ever before to impact positively obesity, diabetes, and their complications, such as renal and cardiac diseases. It is important to recognise what is available for treatment taking into account diabetes heterogeneity. For those who develop type 2 diabetes (T2DM), effective treatments are available that for the first time have shown a benefit in reducing mortality and macrovascular complications, in addition to the well-established benefits of glucose control in reducing microvascular complications.

Severe insulin resistance syndromes result from primary insulin signaling defects, adipose tissue abnormalities or other complex syndromes. Mutations in TBC1D4 lead to partial insulin signaling defects, characterized mainly by postprandial insulin resistance. We describe an individual with severe insulin-resistant diabetes unresponsive to multiple therapies, in whom exome and genome analyses identified a complex rearrangement in TBC1D4.

Article Synopsis
  • - Dapagliflozin is shown to lower the chances of hospitalization due to heart failure and slow chronic kidney disease progression in patients with or without type 2 diabetes (T2D), though its effect on reducing atherosclerotic events is less certain.
  • - The study aimed to determine if levels of NT-proBNP and hsTnT could help identify T2D patients at higher risk of atherosclerotic events who may benefit more from dapagliflozin treatment.
  • - In a secondary analysis of the DECLARE-TIMI 58 trial involving over 14,000 patients, both NT-proBNP and hsTnT were significantly linked to the risk of major adverse cardiovascular events (MACE)

Activated PI3Kδ Syndrome (APDS) is a rare inherited inborn error of immunity caused by mutations that constitutively activate the p110 delta isoform of phosphoinositide 3-kinase (PI3Kδ), resulting in recurring pulmonary infections. Currently no licensed therapies are available. Here we report the results of an open-label trial in which five subjects were treated for 12 weeks with nemiralisib, an inhaled inhibitor of PI3Kδ, to determine safety, systemic exposure, together with lung and systemic biomarker profiles (Clinicaltrial.

SGLT2 inhibitors (SGLT2i) are effective in the management of diabetes and in reducing adverse cardiovascular and renal outcomes. Randomized clinical trials demonstrated safety and tolerability in older adults. Adverse effects associated with SGLT2i are impacted by patient frailty, comorbidities, and concomitant medication use and, therefore, must be thoroughly evaluated before initiating treatment.

Article Synopsis
  • Dapagliflozin has been found to improve cardiovascular and kidney outcomes in individuals with type 2 diabetes, but its safety and effectiveness, especially when combined with common heart medications, was not well-studied prior to this research.
  • The study analyzed data from a previous large trial (DECLARE-TIMI 58) involving 17,160 patients to evaluate how dapagliflozin performs both with and without concurrent cardiovascular medications like ACE inhibitors, beta-blockers, and diuretics.
  • Results indicated that changes in blood pressure and kidney function over 48 months were similar for patients on dapagliflozin, regardless of whether they were also taking other heart medications.

Background: Currently the only available therapies for fibrotic Interstitial Lung Disease are administered systemically, often causing significant side effects. Inhaled therapy could avoid these but to date there is no evidence that drug can be effectively delivered to distal, fibrosed lung. We set out to combine mass spectrometry and histopathology with rapid sample acquisition using transbronchial cryobiopsy to determine whether an inhaled drug can be delivered to fibrotic, distal lung parenchyma in participants with Interstitial Lung Disease.

Article Synopsis
  • Dapagliflozin has shown to improve heart failure and kidney-related outcomes in patients with type 2 diabetes, particularly in those with or at high risk for cardiovascular disease, as demonstrated in the DECLARE-TIMI 58 trial.
  • The trial involved 17,160 patients and assessed the medication's effects based on different levels of baseline systolic blood pressure (SBP) while monitoring both efficacy outcomes (like hospitalization for heart failure) and safety outcomes (like acute kidney injury).
  • Results indicated that dapagliflozin decreased SBP and its benefits for heart and kidney health were consistent across various BP categories, with no serious safety issues related to the drug compared to placebo.
