Self-Coding of Fidelity as a Potential Active Ingredient of Consultation to Improve Clinicians’ Fidelity

A key goal for implementation science is the identification of evidence-based consultation protocols and the active ingredients within these protocols that drive clinician behavior change. The current study examined clinicians’ self-coding of fidelity as a potential active ingredient of consultation for the Attachment and Biobehavioral Catch-up (ABC) intervention. It also examined two other potential predictors of clinician fidelity in response to consultation: dosage of consultation and working alliance. Twenty-nine clinicians (97% female, 62% White, M age?=?34 years) participated in a year of weekly fidelity-focused ABC consultation sessions, for which clinicians self-coded fidelity and received consultant feedback on both their coding and their fidelity. Data from the ABC fidelity measure were available for 1067 sessions coded by consultants, and clinicians’ self-coding accuracy was calculated from 1044 sessions coded by both clinicians and consultants. Alliance was measured with the Working Alliance Inventory—Trainee and Supervisor Versions. The study was observational, and fidelity and self-coding accuracy were modeled across time using hierarchical linear modeling. Clinicians’ ABC fidelity, as well as their self-coding accuracy, increased over the course of consultation. Clinicians’ self-coding accuracy predicted their initial fidelity and growth in fidelity. Working alliance was also linked to fidelity and self-coding accuracy. These results suggest that clinician self-coding should be further examined as an active ingredient of consultation. The study has important implications for the design of consultation procedures and fidelity assessments.

     

Congenital toxoplasmosis. Report of a case treated with spiramycin in the 24th week of pregnancy]

The Authors present one case of congenital toxoplasmosis; it was sustained by a primary maternal infection, contracted at the XXIII week of gestation. Even if we started the treatment with spiramycin at the XXIV week of gestation, both the prenatal ultrasound examination of the fetus, and the postnatal investigation of the newborn, showed that the young patient was affected by a severe form of congenital toxoplasmosis.     

CTLA-4 is required for the induction of high dose oral tolerance

Mucosal and systemic administrations of high dose antigens induce long- lasting peripheral T cell tolerance. We and others have shown that high dose peripheral T cell tolerance is mediated by anergy or deletion and is preceded by T cell activation. Co-stimulatory molecules B7-1 (CD80)/B7-2 (CD86) and their counter-receptors CD28/CTLA-4 play pivotal roles in T cell activation and immune regulation. In the present study, we examined the roles of the B7 co-stimulation pathway in the generation of high dose peripheral T cell tolerance. We found that blocking B7:CD28/CTLA-4 interaction at the time of tolerance induction partially prevented T cell tolerance, whereas selective blockade of B7:CTLA-4 interaction completely abrogated peripheral T cell tolerance induced by either oral or i.p. antigens. These results suggest that CTLA-4-mediated feedback regulation plays a crucial role in the induction of high dose peripheral T cell tolerance.

Taking a patient-oriented approach in exercise interventions for pregnant women: a commentary

Taking a patient-oriented approach to developing lifestyle interventions includes incorporating the patient into the program’s design, delivery, and evaluation. This commentary assumes that a patient-oriented approach has not yet been implemented and tested in exercise-based interventions designed for pregnant women. We outline and define a patient-oriented approach to conduct exercise-based research and review previous physical activity interventions designed for pregnant women to determine whether a patient-oriented approach was applied. In addition, pregnant women living with obesity may have unique barriers to engaging in prenatal exercise interventions that have not been previously addressed, such as having experienced weight stigma before pregnancy in healthcare and fitness settings. We propose suggestions for future trials to effectively take a patient-oriented approach when designing and implementing prenatal exercise interventions to address patient-informed barriers and incorporate suggested facilitators for physical activity. Given that prenatal activity levels are low and pregnant women may have unique barriers to engaging in exercise interventions, a patient-oriented approach may be an effective strategy to improve inclusivity and equity and, as a result, increase uptake and adherence to the intervention.     

Dietary carbohydrate and its effects on metabolism and substrate stores in sedentary and active individuals.

This review of carbohydrate (CHO) ingestion and exercise addresses three major issues: (a) how CHO ingestion influences CHO and fat stores, (b) how exercise, by changing CHO stores, alters the responses to CHO or fat ingestion, and (c) the roles of CHO in exercise performance and metabolism. Dietary manipulation is not a simple issue; increasing the dietary content of any specific nutrient alters the entire diet composition. High CHO diets are often low fat diets, hence changing the metabolism and storage of both fat and CHO. Acute CHO ingestion increases CHO oxidation and the "spared" fats are deposited as fat. Chronic high CHO ingestion (without an active lifestyle) leads to muscle becoming insulin-insensitive, adipose tissue processing CHO to fatty acids, and the liver increasing production of VLDL triglycerides. CHO ingestion prior to and during prolonged exercise can increase endurance. It has been suggested that moderate or low glycemic index forms be used prior to and during the exercise, but there is no consensus as to whether it should be a recommendation. The physiological nature of the regulation of CHO stores is poorly understood, but the recent identification of a key enzyme, glycogenin, and two forms of glycogen (pro- and macroglycogen) show promise of a deeper understanding.     

Laparoscopic Heller's myotomy for achalasia after gastric bypass: A case report

INTRODUCTIONDisorders of the oesophagus have been linked to surgical bariatric procedures and obesity. However the relationship between achalasia and gastric bypass is not clearly understood and has only recently been reported following gastric bypass.PRESENTATION OF CASEWe present the case of a 53-year-old woman who re-presented following a gastric bypass with a new diagnosis of achalasia. This was treated successfully with laparoscopic Heller's Myotomy with discharge from hospital 10 days post operatively.DISCUSSIONIt is not clear whether achalasia is a complication of gastric bypass procedures. This is only the second reported case of the condition developing after this operation. The mechanism by which it may develop is yet to be clearly established.CONCLUSIONThis case highlights the need to investigate further a possible link between achalasia and gastric bypass and to manage susceptible patients accordingly in the pre-operative stage.
