Utility of Diabetes Type–Specific Genetic Risk Scores for the Classification of Diabetes Type Among Multiethnic Youth

OBJECTIVEGenetic risk scores (GRS) aid classification of diabetes type in White European adult populations. We aimed to assess the utility of GRS in the classification of diabetes type among racially/ethnically diverse youth in the U.S.RESEARCH DESIGN AND METHODSWe generated type 1 diabetes (T1D)- and type 2 diabetes (T2D)-specific GRS in 2,045 individuals from the SEARCH for Diabetes in Youth study. We assessed the distribution of genetic risk stratified by diabetes autoantibody positive or negative (DAA^+/−) and insulin sensitivity (IS) or insulin resistance (IR) and self-reported race/ethnicity (White, Black, Hispanic, and other).RESULTST1D and T2D GRS were strong independent predictors of etiologic type. The T1D GRS was highest in the DAA⁺/IS group and lowest in the DAA⁻/IR group, with the inverse relationship observed with the T2D GRS. Discrimination was similar across all racial/ethnic groups but showed differences in score distribution. Clustering by combined genetic risk showed DAA⁺/IR and DAA⁻/IS individuals had a greater probability of T1D than T2D. In DAA⁻ individuals, genetic probability of T1D identified individuals most likely to progress to absolute insulin deficiency.CONCLUSIONSDiabetes type–specific GRS are consistent predictors of diabetes type across racial/ethnic groups in a U.S. youth cohort, but future work needs to account for differences in GRS distribution by ancestry. T1D and T2D GRS may have particular utility for classification of DAA⁻ children.     

Effect of the Affordable Care Act on healthcare utilization for Veterans with spinal cord injuries and disorders

Context/Objective: Provisions of the Affordable Care Act (ACA) potentially increase insurance options for Veterans with disabilities. We examined Veterans with spinal cord injuries and disorders (SCI/D) to assess whether the ACA was associated with changes in healthcare utilization from Department of Veterans Affairs (VA) healthcare facilities.Design: Using national VA data, we investigated impacts on VA healthcare utilization pre- (2012/13) and post-ACA (2014/15) implementation with negative binomial regression models.Setting: VA healthcare facilities.Participants: 8,591 VA users with SCI/D. Veterans with acute myelitis, Guillain-Barré syndrome, multiple sclerosis, or amyotrophic lateral sclerosis were excluded as were patients who died during the study period.Interventions: We assessed VA healthcare utilization before and after ACA implementation.Outcome Measures: Total numbers of VA visits for SCI/D care, diagnostic care, primary care, specialty care, and mental health care, and VA admissions.Results: The number of VA admissions was 7% higher in the post than pre-ACA implementation period (P < 0.01). The number of VA visits post-implementation increased for SCI/D care (8%; P < 0.01) and specialty care (12%; P < 0.001). Conversely, the number of mental health visits was 17% lower in the post-ACA period (P < 0.001). Veterans with SCI/D who live <5 miles from their nearest VA facility received VA care more frequently than those ≥40 miles from VA (P < 0.001).Conclusion: Counter to expectations, results suggest that Veterans with SCI/D sought more frequent VA care after ACA implementation, indicating Veterans with SCI/D continue to utilize the lifelong, comprehensive care provided at VA.     

A programmed training technique that uses reinforcement to facilitate acquisition and retention in brain-damaged patients

Hospitalized brain-damaged patients were Ss in a study designed to evaluate the effectiveness of a treatment technique used with contingent reinforcement to facilitate acquisition and retention of environmentally relevant information. Ss were divided into three groups that were equated diagnostically and demographically. Group I received the treatment technique with contingent material and verbal reinforcement. Group II received the treatment technique with only contingent verbal reinforcement, and Group III was a control. Both treatment groups showed significant acquisition of the experimental information, and 1 week after training the two treatment groups showed no significant loss of acquired information. None of the groups showed any significant change in ward behavior during the experiment. It was concluded that the treatment technique used with contingent reinforcement can be used in the retraining of memory in brain-damaged patients.     

Impact of Parent-Provided Distraction on Child Responses to an IV Insertion

This study evaluates the impact of parent-provided distraction on children's responses (behavioral, physiological, parent, and self-report) during an IV insertion. Participants were 542 children, 4 to 10 years old, randomized to an experimental group that received a parent distraction coaching intervention or to routine care. Experimental group children had significantly less cortisol responsivity (p = .026). Children that received the highest level of distraction coaching had the lowest distress on behavioral, parent report, and cortisol measures. When parents provide a higher frequency and quality of distraction, children have lower distress responses on most measures.     

Can parturients identify the midline during neuraxial block placement?

Study Objective

To determine whether parturients can reliably identify their midline during epidural or spinal needle insertion, and to determine whether parturient feedback helps the anesthesiologist successfully identify the midline.

Design

Survey instrument completed by anesthesiologists.

Setting

Labor and delivery unit of a university-based, tertiary-care hospital.

Measurements

Completed questionnaires were obtained for 554 of 904 (61.3%) neuraxial blocks. Data were collected on the type of neuraxial block, number of needle redirections required to identify the midline, the patient's height and weight, the patient's position during block placement, whether the patient was questioned for assistance identifying the midline, and if so, how helpful the patient was in redirecting the needle to locate the epidural or subarachnoid space.

Main Results

The anesthesiologist requested the assistance of 194 patients (35.0%) for needle location. Of those questioned, the anesthesiologist reported 128 instances (66.0%) when the patient's response was helpful in identification of the midline. Morbidly obese parturients (BMI > 35 kg/m²) were questioned more often than their non-morbidly obese counterparts (48.9% vs. 30.5%; P < 0.0005). Of those morbidly obese parturients who were questioned (n = 64), 76.6% were reported by the anesthesiologist to be helpful.

Conclusions

Most patients, including morbidly obese patients, are helpful in identifying the midline during neuraxial anesthesia.     

Is the foot structure of preschool children moderated by gender?

OBJECTIVE: Although boys are frequently reported to have flatter feet than girls, there has been little systematic research to confirm or explain this structural difference between the genders. The objective of this study was to determine whether flat-footedness was moderated by gender in Australian preschool children and, if so, to determine the cause of this between-gender difference in structure of the plantar surface of the foot. METHODS: Foot anthropometry, Arch Index derived from plantar footprints, and midfoot plantar fat pad thickness measured by ultrasound were obtained for the left and right feet of 52 girls and 36 boys (mean age, 4.2 +/- 0.6 years). The children were recruited from 10 randomly selected preschools from the Illawarra region of New South Wales, Australia. RESULTS: In agreement with previous research, the preschool boys displayed significantly flatter feet than the girls (P < or = 0.04). Although there were no between-gender differences in structural foot dimensions, the boys had a significantly thicker midfoot fat pad than the girls by approximately 0.4 and 0.5 mm on both the right and left feet, respectively. CONCLUSIONS: The increased incidence of flat-footedness in boys compared with girls of the same age seems to be caused by a thicker plantar fat pad in the medial midfoot in boys. This suggests that the development of the medial longitudinal arch may be progressing at a slower rate in boys than in girls, and that intervention for a flexible flat foot, particularly for young boys, may be unnecessary.     

Cell membrane and mitotic markers show that the neonatal rat gubernaculum grows in a similar way to an embryonic limb bud

Aim/Background

How the gubernaculum guides the testis into the scrotum remains controversial, with various proposals from passive inversion to active growth. We aimed to determine if the gubernaculum contains an area of active proliferation, such as a “progress zone” in a growing embryonic limb bud, using a fluorescent cell membrane marker, 1,1′-didodecyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate [DiIC₁₂(3)], to trace cell migration, and 5-bromodeoxyuridine (BUDR) (a thymidine analogue) as a mitotic marker.

Methods

Gubernacula were collected from neonatal male rats (n = 42, day 1-2, Sprague-Dawley) and cultured with calcitonin gene-related peptide (CGRP; 714 nmol/L). 1,1′-didodecyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate-coated glass beads (diameter, 150-212 μm) were placed next to the bulb for the first 3 hours. Gubernacula were cultured for 3, 18, and 24 hours, then frozen sections cut and examined by confocal microscopy (wavelength, 549 nm). In a second experiment, pups not exposed to exogenous CGRP (n = 53, day 0, Sprague-Dawley) were injected intraperitoneally with BUDR (50 mg/kg of body weight); gubernacula were collected at 2, 48, 72, and 96 hours postinjection (PI), sectioned, and stained using immunohistochemistry to count the number of BUDR-positive cells per 100 cells (labeling index) in the bulb, cremaster, cord, and epididymis.

Results

After 24 hours' culture with CGRP, the bulb showed an oval region (diameter, 300 μm) of high fluorescence, and the cremaster region showed elongated cells migrating out of the bulb. When cultured without CGRP, the same oval region contained no fluorescence. In vivo BUDR labeling index increased in all areas until 48 hours postinjection and then decreased most rapidly in the bulb (P < .05), in the presence of endogenous CGRP from the genitofemoral nerve.

Conclusions

The rat gubernaculum contains a putative progress zone, such as in a growing limb bud, in the presence of CGRP. Cells migrate out of this zone to form cremaster muscle. We hypothesize that proliferation in the bulb elongates the gubernaculum, whereas proliferation of cremaster cells would increase gubernacular diameter. This brings to “life” the gubernaculum as an actively growing organ in contrast to the inert ligament connecting the testis to the scrotum portrayed in most anatomy textbooks.
