    To optimize the diffusion-weighting b values and postprocessing pipeline for hybrid intravoxel incoherent motion diffusion kurtosis imaging in the head and neck region.

    Optimized diffusion-weighting b value sets ranging between 5 and 30 b values were constructed by optimizing the Cramér-Rao lower bound of the hybrid intravoxel incoherent motion diffusion kurtosis imaging model. With this model, the perfusion fraction, pseudodiffusion coefficient, diffusion coefficient, and kurtosis were estimated. Sixteen volunteers were scanned with a reference b value set and 3 repeats of the optimized sets, of which 1 with volunteers swallowing on purpose. The effects of (1) b value optimization and number of b values, (2) registration type (none vs. intervolume vs. intra- and intervolume registration), and (3) manual swallowing artifact rejection on the parameter precision were assessed.

    The SD was higher in the reference set for perfusion fraction, diffusion coefficient, and kurtosis by a factor of 1.7, 1.5, and 2.ol efficiency, with a precision comparable to larger b value sets and a 50% reduction in scan time.

    Long wait times for in-person appointments in pediatric dermatology can lead to delays in specialty care, additional health system touchpoints, patient and family dissatisfaction, poorer outcomes, and increased overall health care costs. Store-and-forward teledermatology may address these challenges and improve access to care in pediatric dermatology.

    We describe a prospective, non-blinded cohort study with follow-up surveys conducted from March 1, 2018, to September 20, 2018. The study was conducted at a single center, in primary care and specialist settings. Patients included were <18years old and received care at one of our affiliated primary care sites. Primary care providers submitted teledermatology consultations through a shared electronic medical record. A board-certified pediatric dermatologist evaluated each consultation; primary care providers conveyed recommendations to families.

    Forty-three consultations for patients (23 male, 20 female; median age 7years ) were entered by primary care providers. Median time from consult request to dermatologist initiating consult was 12.1hours ; median time to complete consult note was 7minutes . Median time from primary care provider initially consulting to conveying teledermatology recommendations to families was 3days . All but one consult (42/43, 98%) were completed in the intended workflow. Follow-up in-person visits with pediatric dermatologists occurred with 10/43 (23%) patients. In follow-up surveys, parents were 83% likely to recommend the service to family and friends. All primary care providers and dermatologists felt the service improved quality of care.

    Provider-to-provider teledermatology consultation appears to be a feasible and acceptable method of providing care quickly and effectively to pediatric patients.

    This study examined the relationship between childhood adversities and major depression in older adults over 8 years.

    The study sample consisted of 16 946 participants aged 51 years and older from the US Health and Retirement Study. Major depression was assessed using the Composite International Diagnostic Interview. Competing-risks regression analysis was conducted to examine the impact of each childhood adversity on late-life major depression and the potential moderation effects of sex, race/ethnicity, and adulthood trauma.

    After controlling for covariates, childhood adversities including physical abuse by a parent (subdistribution hazard ratio = 1.67, 95% confidence interval = 1.49-1.89, P < .001), trouble with the police (SHR = 1.31, 95% CI = 1.13-1.54, P = .001), receiving help because of financial difficulties (SHR = 1.17, 95% CI = 1.05-1.31, P = .006), and parental substance abuse (SHR = 1.11, 95% CI = 1.01-1.23, P = .037) were associated with a higher rate of major depression in later life. The association of physical abuse and major depression was stronger for men than women (SHR = 1.46, 95% CI = 1.15-1.85, P = .002), despite an overall lower risk of major depression among men. Potential adulthood trauma had a weaker association with late-life major depression in the presence of childhood physical abuse (SHR = 0.91, 95% CI = 0.85-0.98, P = .015). There was a significant dose-response relationship (SHR = 1.20, 95% CI = 1.16-1.24, P < .001).

    Childhood adversities increase the risk of major depression in later life, particularly for those who experienced physical abuse and trouble with the police. Men may be more susceptible to the mental health detriments of childhood adversities.

    The analysis of longitudinal birth cohorts with micro-arrayed allergen molecules has provided interesting information about the evolution of IgE sensitization in children. Ridaforolimus However, so far no cross-sectional study has been performed comparing IgE sensitization profiles in children with and without symptoms of allergy. Furthermore, no data are available regarding molecular IgE sensitization profiles in children from Russia.

    We recruited two groups of age- and gender-matched children, one (Group 1 n=103; 12.24±2.23years; male/female 58/45) with symptoms and a second (Group 2 n=97; 12.78±2.23years; male/female 53/44), without symptoms of allergy according to international ISAAC questionnaire. Children were further studied regarding symptoms of allergy (rhinitis, asthma, atopic dermatitis) according to international guidelines, and skin prick testing with a panel of aeroallergen extracts was performed before sera were analyzed in an investigator-blinded manner for IgE specific to more than 160 micro-arrayed allergen molecules using ImmunoCAP ISAC technology.
