Recently, hydrogen isotope exchange (HIE) reactions have experienced impressive development due to the growing importance of isotope containing compounds in various fields including materials and life sciences, in addition to their classical use for mechanistic studies in chemistry and biology. Tritium-labeled compounds are also of crucial interest to study the in vivo fate of a bioactive substance or in radioligand binding assays. Over the past few years, deuterium-labeled drugs have been extensively studied for the improvement of ADME (absorption, distribution, metabolism, excretion) properties of existing bioactive molecules as a consequence of the primary kinetic isotope effect. Furthermore, in the emergent "omic" fields, the need for new stable isotopically labeled internal standards (SILS) for quantitative GC- or LC-MS analyses is increasing. Because of their numerous applications, the development of powerful synthetic methods to access deuterated and tritiated molecules with either high isotope incorpoy represent innovative tools combining the advantages of both methods for the isotopic labeling and activation of C-H bonds of complex molecules.Background Evidence on effective strategies to ensure sustainability of research capacity strengthening interventions in low- and middle-income country (LMIC) institutions is lacking. This systematic review identified publications describing research capacity building programs and noted their effect, their contexts, and the mechanisms, processes and social actors employed in them. Methods We searched online databases for the period 2011-2018. Inclusion criteria were that the publications 1) described the intervention; 2) were implemented in LMICs; 3) were based in, or relevant to, university staff or post docs; 4) aimed to improve research capacity; 5) aimed to effect change at the institutional level. Two reviewers screened titles, abstracts and full text in consecutive rounds, a third resolved disagreements. Two people extracted the data of each full text using a data extraction tool covering data relevant to our question. Results In total 4052 citations were identified and 19 papers were included, which reity strengthening community can extract important lessons.
Dental anxiety distresses children and their families with consequent poor oral health and costly pediatric dental services. Children's behaviors could be modified using a distraction technique for improved dental treatment. The study evaluates the effects of an audio-visual distraction on children's behaviors and pain expressions during dental treatment.
One hundred healthy children, between 4 and 6 years of age, were randomly assigned to one of two groups audio visual distraction (AVD, N=61) group and control (CTR, N=39) group. The pre and post pain expression was collected using a faces pain rating scale from the participated children. Children's behavior was evaluated using the Frankl behavior rating scale by the assigned dentist. Data was analyzed using chi-squared tests and analysis of variance.
The AVD group demonstrated more "definitely positive" behavior (91.8%) compared to the CTR group (35.9%) based on the Frankl scale evaluation from pre- and post-treatment (p < 0.0001). The pain rating scale did not demonstrate a significant difference in post-treatment pain scales (p=0.2073) or changes in pain (p=0.1532) between the AVD group and CTR group.
The AVD is an effective distraction tool for young children during dental treatment regardless of child's subjective pain expression.

Numerous attempts have been made to investigate nocturnal heart rate (HR) and its variability (HRV) as potential pathophysiological hallmarks of altered arousal levels in insomnia, with mixed results. We have aimed to overcome some of the pitfalls of previous studies by using a young, medication-free, age- and gender-matched population consisting of 43 students aged 18-30 years half with a subthreshold insomnia complaint. We employed at-home ambulatory polysomnography and compared this attenuated insomnia group to a good sleeping group. The poor sleepers had significantly higher wake after sleep onset, arousal count, mean HR in all sleep stages (with the exception of Stage 1) and lower sleep efficiency. Consistent with previous research, we also found a significant group-by-sleep stage interaction in the prediction of nocturnal HR, highlighting the insomnia group to have a lower wake-sleep HR reduction compared to good sleepers. When restricting our analyses to insomnia with objectively determined short sleep duration, we found significantly lower standard deviation of RR intervals (SDNN; a measure of HRV) compared to good sleepers. Taken together, this lends credence to the hyperarousal model of insomnia and may at least partially explain the increased prevalence of cardiovascular morbidity and mortality observed in patients with insomnia.
Electronic medical records-based alerts have shown mixed results in identifying ED sepsis. Augmenting clinical patient-flagging with automated alert systems may improve sepsis screening. this website We evaluate the performance of a hybrid alert to identify patients in ED with sepsis or in-hospital secondary outcomes from infection.
We extracted a dataset of all patients with sepsis during the study period at five participating Western Sydney EDs. We evaluated the hybrid alert's performance for identifying patients with a discharge diagnosis related to infection and modified sequential sepsis-related organ functional assessment (mSOFA) score ≥2 in ED and also compared the alert to rapid bedside screening tools to identify patients with infection for secondary outcomes of all-cause in-hospital death and/or intensive care unit admission.
A total of 118 178 adult patients presented to participating EDs during study period with 1546 patients meeting ED sepsis criteria. The hybrid alert had a sensitivity - 71.2% (95% confidence interval 68.
