[Unfractionned heparin wastage at a French university hospital]. / Gaspillage d'héparine sodique dans un centre hospitalo-universitaire français.

OBJECTIVES: In a context of heparin shortage, we studied the wasted quantities in three intensive care units (ICU) of a university hospital where two electric syringe pump (ESP) heparin protocols coexist (20,000UI/48mL used in the cardiology ICU and 25,000UI/50mL use in the medical and surgical ICUs). METHOD: We performed a prospective observational study of patients treated with heparin ESP. We collected the information recorded in the prescription software connected to the ESP (dosage, start time, infusion rate, interruption times, date and time of end of treatment). We observed the ESPs, noted the time of start written on the label and the quantity remaining, and questioned nurses about the constraints that lead for changing the ESPs. RESULTS: Between 23/03/23 and 19/05/23, 164 vials of 25,000UI/5mL were used. The wasted quantity was equivalent 42 vials: 18 vials (43%) of treatment stopped, nurses practices such as changing the ESP in advance 6 vials (14%), application of the rule "discard the ESP 24hours after preparation" 9 vials (21.5%) and 9 vials (21.5%) corresponding to the 45mL discarded for the 45 ESP prepared in the cardiology ICU. CONCLUSION: More than a quarter of the heparin purchased is wasted. The results should lead to policy decisions concerning the medications supply chain, i.e. abandoning the 20,000UI/48mL protocol, supply of ready to use heparin syringes by industry or by the pharmacy. It is essential that these data be fed back to nurses' teams, in order to gather their suggestions before considering any changes of their practices.

Recent advances in JAK inhibitors for the treatment of metabolic syndrome.

With an epidemic spread, metabolic syndrome represents an increasingly emerging risk for the population globally, and is currently recognized as a pathological entity. It is represented by a cluster of different conditions including increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol or triglyceride levels. These conditions lead directly to several disorders, including obesity, dyslipidemia, hyperglycaemia, insulin resistance, impaired glucose tolerance and hypertension causing an increase in cardiovascular risk and in particular atherosclerotic disease. Despite efforts to promote healthier lifestyles through exercise, reduced caloric intake, and improved dietary choices, the incidence and prevalence of metabolic syndrome continue to rise worldwide. Recent research has highlighted the involvement of signaling pathways in chronic inflammatory conditions like obesity and type 2 diabetes mellitus, revealing the significance of the JAK/STAT pathway in atherosclerotic events. This pathway serves as a rapid membrane-to-nucleus signaling module that regulates the expression of critical mediators. Consequently, JAK inhibitors (JAKi) have emerged as potential therapeutic options for metabolic diseases, offering a promising avenue for intervention. The aim of this review is to shed light on the emerging indications of JAK inhibitors in metabolic syndrome, emphasizing their potential role in attenuating associated inflammatory processes, improving insulin sensitivity, and addressing cross-talk with the insulin pathway, with the intention of contributing to efforts in the field of inflammation pharmacology.
