Hsp90 inhibitor 17AAG degraded TGFβRII by a ubiquitin-proteasome pathway, co-immunoprecipitation showed an interaction between Hsp90 and TGFβRII in PSCs.

The study suggests that an Hsp90 inhibitor 17AAG remarkable prevents the development of pancreatic fibrosis in caerulein-induced CP mice, and suppresses activation and extracellular matrix accumulation of PSCs in vitro. The current results provide a potential treatment strategy based on Hsp90 inhibition for pancreatic fibrosis in CP.

Desmopressin (DDAVP) is often used for hyponatremia management but has been associated with increases in hospital length of stay and duration of hypertonic saline use. The purpose of this study was to evaluate hyponatremia management strategies and their effect on sodium correction in critically ill patients requiring 3% hypertonic saline (3HS).

This retrospective, single-center study included critically ill patients with hyponatremia (serum sodium ≤ 125mEq/L) receiving 3HS from May 31 2015, to May 31 2019. Patients were divided into those who received 3HS for hyponatremia management (HTS) and those who received proactive or reactive DDAVP in addition to 3HS (D-HTS). Patients in either group could receive rescue DDAVP. The primary outcome was the percentage of patients achieving goal sodium correction of 5-10mEq/L 24h after 3HS initiation.

Goal sodium correction was achieved in 52.5% of patients in HTS compared to 65.6% of patients in D-HTS (p=0.21). Patients in HTS had a shorter duration of 3HS infusion (p=0.0022) with no difference in ICU length of stay, free water intake, urine output, or serum sodium increases 12 and 24h after receiving 3HS. Overcorrection during any 24- or 48h period was not statistically different between groups.

Patients in HTS and D-HTS had similar rates of achieving goal sodium correction at 24h. A proactive or reactive DDAVP strategy led to an increase in 3HS duration and total amount with no significant difference in rates of overcorrection. Prospective, randomized studies assessing standardized strategies for hyponatremia management and DDAVP administration are warranted.

Patients undergoing hematopoietic cell transplantation (HCT) are at high risk for acute kidney injury (AKI). The etiology of AKI is often multifactorial and includes exposure to antibiotics and calcineurin inhibitors (CNI) for prevention of graft versus host disease.

This is a retrospective, single center study which evaluated patients undergoing inpatient HCT at Froedtert Memorial Hospital, Milwaukee, Wisconsin from Jan 1 to Dec 31, 2016. AKI was defined as an increase in serum creatinine >0.3mg/dL from baseline value.

The total number of patients included in the study was 280, 64 had AKI and 216 were in the non-AKI group. AKI was noted in 23% patients. Lenalidomide hemihydrate datasheet Exposure to CNI or vancomycin accounted for the majority of the cases (82%). The median pre-AKI vancomycin trough was elevated in the AKI group at 21.3 mcg/Ml (range 17.4-24.4 mcg/Ml) while the pre-AKI CNI trough was lower in the AKI group at 12.3ng/Ml (range 8.7-14.7ng/Ml).There were also a higher number of ICU transfers (19%) and higher 100 day mortality (15.6%) in the AKI group.

AKI is a frequent complication following HCT and is associated with a higher risk of ICU transfer and higher mortality post HCT. While a higher vancomycin trough level may be indicative of a higher risk of AKI, the risk following CNI exposure may not be related to trough levels alone. There may be underlying pharmacogenetic factors which may alter the risk of AKI with CNI use.

These types of behavior can cause nutrition-related diseases such as obesity, which affects more than 650 million people worldwide. Ghrelin and leptin are key hormones that regulate appetite, food intake and energy metabolism. Research in genetics suggests that genetic variants of both hormones are associated with complex forms of eating behavior, such as a preference for palatable food, making individuals susceptible to the modern obesogenic environment. This review analyses the scientific evidence around polymorphisms in the ghrelin and leptin genes and their association with eating behavior. The understanding of these mechanisms is relevant since it could impact on the objectives of pharmacological or behavioral interventions for their treatment.

Bariatric surgery aims to reduce weight and resolve the comorbidities associated with obesity. Few studies have assessed mid/long-term changes in lipid profile with sleeve gastrectomy versus gastric bypass. This study was conducted to assess and compare changes in lipid profile with each procedure after 60 months.

This was an observational, retrospective study of analytical cohorts enrolling 100 patients distributed into two groups 50 had undergone gastric bypass (GBP) surgery and 50 sleeve gastrectomy (SG) surgery. Total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels were measured before surgery and at 1, 6, 12, 24, 36, 48 and 60 months. Weight loss and the resolution of dyslipidemia with each of the procedures were also assessed.

Ninety-five of the 100 patients completed follow-up. At 60 months, TC and LDL levels had significantly decreased in the GBP group (167.42±31.22mg/dl and 88.06±31.37mg/dl, respectively), while there were no differences in the SG group.
