Aim: To identify and describe microcirculatory dysfunction (MD) in severe COVID-19 cases. Methods: This prospective, cohort study evaluated microvascular function in COVID-19 patients with acute respiratory failure not requiring mechanical ventilation and compared it with that of non-COVID-19 intensive care unit (ICU)-matched controls. A validation cohort included healthy, comorbidity-free patients. ⋯ This study's reproducible multimodal approach facilitates acute MD detection across multiple clinical applications. Limitations included the observational design, limited statistical power, single-time microvascular measurements, varying illness severity among groups, and possible influences of treatments and vaccinations on MD. Trial registration : Clinical-Trials.gov (NCT04773899).

Diabetic Nephropathy is one of the most severe complications of Diabetes Mellitus and the main cause of end-stage kidney disease worldwide. Despite the therapies available to control blood glucose and blood pressure, many patients continue to suffer from progressive kidney damage. Chronic hyperglycemia is the main driver of changes observed in diabetes; however, it was recently discovered that inflammation and oxidative stress contribute to the development and progression of kidney damage. Therefore, it is important to search for new pharmacological therapies that stop the progression of DN. Sodium tungstate (NaW) is an effective short and long-term antidiabetic agent in both type 1 and type 2 diabetes models. ⋯ NaW could be an effective drug therapy for treating human diabetic nephropathy.

Hemorrhagic shock (HS) is a life-threatening condition with high mortality rates despite current treatments. This study investigated whether targeted temperature management (TTM) could improve outcomes by modulating inflammation and protecting organs following HS. Using a rat model of HS, TTM was applied at 33°C and 36°C after fluid resuscitation. ⋯ Cytokine array analysis confirmed reduced levels of proinflammatory cytokines with TTM at 36°C. These results collectively highlight the potential of TTM at 36°C as a therapeutic approach to improve outcomes in HS. By addressing multiple aspects of injury and inflammation, including modulation of macrophage responses and cytokine profiles, TTM at 36°C offers promising implications for critical care management after HS, potentially reducing mortality and improving patient recovery.

The current analgesics often prevent patients from getting effective treatment due to their adverse effects. Cannabidiol (CBD) is well tolerated, has few side effects and has been extensively investigated in analgesia. However, its oral bioavailability is extremely low. In order to solve this problem, we developed the cannabidiol nanocrystals (CBD-NC) in the earlier stage. ⋯ The absolute bioavailability of the CBD-NC intramuscular injection formulation can reach 203.31%, which can solve the problem of low oral bioavailability. This research evaluated the therapeutic effect of CBD-NC on NP associated with the SNI model for the first time. All available date showed that whatever the analgesic or neuroprotective effect of CBD-NC, it was significantly better than that of CBD oil sol., which was consistent with the results of the pharmacokinetic. This research supports the initiation of more trials testing the efficacy of CBD-NC for treating NP.

Restoration of mesenteric lymphatic microcirculation is crucial for alleviating severe hemorrhagic shock-induced death. Exercise preconditioning (EP) enhances adaptability and resistance to injury and disease. The mitochondria-associated endoplasmic reticulum membrane (MAM) plays a crucial role in the energy and information exchange between the two organelles. ⋯ Importantly, treatment with 2-APB (IP3R1 inhibitor) or VBIT-12 (VDAC1 inhibitor) prolonged the survival time, improved mesenteric lymphatic contractility in vivo , ameliorated the MAM ultrastructure injury, and decreased the IP3R1 or VDAC1 expressions in LSMCs in rats following hemorrhagic shock. In contrast, the administration of drinking water containing CdCl 2 (IP3R1 activator) abolished the beneficial effect of EP on hemorrhagic shock. Taken together, the protective effect of EP on lymphatic contractility following hemorrhagic shock was achieved by improving MAM in LSMCs.
