During pregnancy of type 1 diabetes (T1D) women, a C peptide rise has been described, which mechanism is unclear. In T1D, a defect of regulatory T cells (Tregs) and its major controlling cytokine, interleukin-2 (IL2), is observed.

Evolution of clinical, immunological (Treg (CD4+CD25hiCD127-/loFoxp3+ measured by flow cytometry and IL2 measured by luminex xMAP technology) and diabetes parameters (insulin dose per day, HbA1C, glycaemia, C peptide) was evaluated in 13 T1D women during the three trimesters of pregnancy and post-partum (PP, within 6 months) in a monocentric pilot study. Immunological parameters were compared with those of a healthy pregnant cohort (QuTe).

An improvement of beta cell function (C peptide rise and/or a decrease of insulin dose-adjusted A1c index that estimate individual exogenous insulin need) was observed in seven women (group 1) whereas the six others (group 2) did not display any positive response to pregnancy. A higher level of Tregs and IL2 was observed in group 1 compared to group 2 during pregnancy and at PP for Tregs level. However, compared to the healthy cohort, T1D women displayed a Treg deficiency CONCLUSION This pilot study highlights that higher level of Tregs and IL2 seem to allow improvement of endogenous insulin secretion of T1D women during pregnancy.

The pharmacological action of SGLT2 inhibitors is simply the release of glucose into urine; however, precisely how SGLT2 inhibitors contribute to the health of those with diabetes has still not been completely elucidated. Towards this end, the present review provides a novel insight into the action of SGLT2 inhibitors by highlighting a neglected fuel-burning system found in proximal tubular cells-'glycolysis'. In addition, exploring the details of the molecular mechanisms and clinical biomarkers of the organ protection conferred by SGLT2 inhibitors is now required to prepare for the next stage of clinical diabetes medicine-the 'post-SGLT2 inhibitor era'.It is well established that myoglobin supports mitochondrial respiration through the storage and transport of oxygen as well as through the scavenging of nitric oxide. However, during ischemia/reperfusion (I/R), myoglobin and mitochondria both propagate myocardial injury through the production of oxidants. Decitabine Nitrite, an endogenous signaling molecule and dietary constituent, mediates potent cardioprotection after I/R and this effect relies on its interaction with both myoglobin and mitochondria. While independent mechanistic studies have demonstrated that nitrite-mediated cardioprotection requires the presence of myoglobin and the post-translational S-nitrosation of critical cysteine residues on mitochondrial complex I, it is unclear whether myoglobin directly catalyzes the S-nitrosation of complex I or whether mitochondrial-dependent nitrite reductase activity contributes to S-nitrosation. Herein, using purified myoglobin and isolated mitochondria, we characterize and directly compare the nitrite reductase activities of mitochondria and myoglobin and assess their contribution to mitochondrial S-nitrosation. We demonstrate that myoglobin is a significantly more efficient nitrite reductase than isolated mitochondria. Further, deoxygenated myoglobin catalyzes the nitrite-dependent S-nitrosation of mitochondrial proteins. This reaction is enhanced in the presence of oxidized (Fe3+) myoglobin and not significantly affected by inhibitors of mitochondrial respiration. Using a Chinese Hamster Ovary cell model stably transfected with human myoglobin, we show that both myoglobin and mitochondrial complex I expression are required for nitrite-dependent attenuation of cell death after anoxia/reoxygenation. These data expand the understanding of myoglobin's role both as a nitrite reductase to a mediator of S-nitrosation and as a regulator of mitochondrial function, and have implications for nitrite-mediated cardioprotection after I/R.We recently reported that hydrogen sulfide (H2S) is a possible relaxation factor in the rat bladder. However, there is no available information about the roles of central H2S in the micturition reflex, so we investigated the effects of centrally administered GYY4137 (H2S donor) and AOAA (H2S synthesis inhibitor) on the micturition reflex in urethane-anesthetized (0.8 g/kg, ip) male Wistar rats. Cystometry was performed before and after the administration of GYY4137 (3 or 10 nmol/rat, icv) or AOAA (30 or 100 μg/rat, icv). In some rats, SR95531 (GABAA receptor antagonist, 0.1 nmol/rat, icv) or SCH50911 (GABAB receptor antagonist, 0.1 nmol/rat, icv) was administered 30 min before GYY4137 administration (10 nmol/rat, icv). Centrally administered GYY4137 dose-dependently prolonged the intercontraction intervals (ICI) without altering maximum voiding pressure (MVP). On the other hand, centrally administered AOAA dose-dependently shortened ICI without altering MVP. The AOAA (30 μg/rat, icv)-induced ICI shortening was reversed in the central presence of GYY4137 (10 nmol/rat, icv). Centrally pretreated SR95531 or SCH50911 significantly attenuated the GYY4137 (10 nmol/rat, icv)-induced prolongation of ICI, respectively. These findings suggest that endogenous brain H2S can inhibit the rat micturition reflex via both GABAA and GABAB receptors in the brain.
To assess the 1-year surgical outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in young to middle-aged patients.

Retrospective case series.

Eyes of patients between 18 and 64 years of age who underwent GATT, with and without concomitant cataract surgery, at 2 academic centers in Montreal, Canada.

Success was defined as intraocular pressure (IOP) between 6 and 21 mmHg (criterion A) or between 6 and 18 mmHg (criterion B) and a relative IOP reduction of 20% or more compared with baseline. Failure consisted of not meeting the success criteria at 2 or more consecutive visits after the first postoperative month, reoperation because of uncontrolled IOP or disease progression, or loss of light perception. Predictors of success and postoperative changes in outcome measures, including IOP and medication use, were assessed. Intraoperative and postoperative adverse events were noted.

Success, IOP, and medication reduction at the 1-year follow-up and baseline predictors of surgical success.

Fifty-six eyes with a mean age of 46.
