Under most conditions, 2,4-dihalopyrimidines undergo substitution reactions at C4. Here we report that Pd(II) precatalysts supported by bulky -heterocyclic carbene ligands uniquely effect C2-selective cross-coupling of 2,4-dichloropyrimidine with thiols. The regioselectivity of this reaction stands in stark contrast to ∼1500 previously reported Pd-catalyzed cross-couplings that favor C4 in the absence of other substituents on the pyrimidine ring.

Background: While many pregnant women accept referrals for smoking cessation support, the uptake of telephone counselling appointments is unknown.
Aims: To determine the uptake rate of Quitline appointments among Australian pregnant women who smoke after being referred by a healthcare provider.
Materials And Methods: Data on attendance at telephone counselling appointments, number of appointments attended, gestational age at referral, referral source and smoking cessation upon completion of the program were requested from Quitline.
Background: While prolonged operative time and increased levels fused have been shown to increase the risk of prolonged intensive care unit (ICU) length-of-stay (LOS), studies are limited in guiding decision-making regarding the need for intensive care postoperatively. This is especially the case among the cohort of adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF); associations between comorbidities and ICU LOS are not well-delineated.
Methods: AIS patients who underwent PSF from January 1st, 2016 to December 1st, 2016 at 101 participating centers were identified using the American College of Surgeons (ACS) National Surgical Quality Im-provement Project (NSQIP) Pediatric database.
Background And Aims: Gastric Alimetry™ (Alimetry, New Zealand) is a new clinical test for gastroduodenal disorders involving simultaneous body surface gastric electrical mapping and validated symptom profiling. Studies have demonstrated a range of distinct pathophysiological profiles, and a classification scheme is now required. We used Gastric Alimetry spectral and symptom profiles to develop a mechanism-based test classification scheme, then assessed correlations with symptom severity, psychometrics, and quality of life.

The collective experience of 'Project Engage' involved co-designing resources to support bereaved parents' involvement in research.
Methods: This study aimed to describe and evaluate the involvement of bereaved parents as co-investigators of a stillbirth research project.
