Unravelling the Role of Sterically Encumbered Ligands in Tuning the Magnetic Properties of Lanthanide-Based D5h Single-Ion Magnets.

Isostructural Dy(III) and Er(III) complexes [L12Ln(H2O)5][I]3·L12·(CH2Cl2) (Ln = Dy (1), Er (3)) and [L22Ln(H2O)5][I]3·L22·(CH2Cl2)2 (Ln = Dy (2), Er (4)), with distorted pentagonal bipyramidal geometry (D5h) around the central metal were synthesized by utilizing two bulky phosphonamide ligands, adamantyl phosphonamide, (Ad)P(O)(NHiPr)2 (L1) and carbazolyl phosphoramide (Cz)P(O)(NHiPr)2 (L2). The resultant complexes were investigated for their magnetic properties in order to elucidate the impact of modification of the coordinating P-O bond environment either by increasing steric bulk and/or introduction of a third P-N bond at the central phosphorus atom. Magnetic studies revealed substantial energy barriers (Ueff) of 640 K and 560 K for Dy compounds 1 and 2, respectively, rendering them as some of the best-performing air-stable SIMs amongst the class of SIMs with D5h symmetry.

Identification of key factors for malnutrition diagnosis in chronic gastrointestinal diseases using machine learning underscores the importance of GLIM criteria as well as additional parameters.

Introduction: Disease-related malnutrition is common but often underdiagnosed in patients with chronic gastrointestinal diseases, such as liver cirrhosis, short bowel and intestinal insufficiency, and chronic pancreatitis. To improve malnutrition diagnosis in these patients, an evaluation of the current Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria, and possibly the implementation of additional criteria, is needed.

Aim: This study aimed to identify previously unknown and potentially specific features of malnutrition in patients with different chronic gastrointestinal diseases and to validate the relevance of the GLIM criteria for clinical practice using machine learning (ML).

Perceptions of a faculty-trainee group mentorship program, the mentorship families program, in a residency training program: results from a cross-sectional survey.

Background: In residency programs, the availability of faculty mentors for traditional dyadic mentorship relationships may be limited. Few frameworks exist for mentorship programs with a combined faculty and peer mentorship approach. The authors developed the Mentorship Families Program (MFP), a faculty-resident group mentorship program within a psychiatry residency program to meet the need for mentorship for a large cohort of residents.

Endoscopic ultrasonography-guided drainage of the pancreatic duct (EUS-PD) in postoperative anastomotic stenosis after previous pancreatic resection.

As an alternative instead of a repeat surgical intervention, results (feasibility, safety, and technical and clinical success rate) of EUS-guided pancreatic duct drainage (EUS-PD) in a consecutive patient cohort because of symptomatic postoperative anastomotic stenosis as part of a unicenter observational study in daily clinical practice are presented.EUS-guided puncture (19-G needle) of the pancreatic duct, pancreaticography, and advancement of a guide wire (0.035 inches) via the anastomosis into the small intestine after previous dilatation of the transgastric access site (using ring knife): 1.
