Examining the Role of Estheticians in Skin Cancer Surveillance.

BACKGROUND: Melanoma and non-melanoma skin cancer are significant causes of mortality. Previous studies regarding skin cancer education in nonmedical professionals have shown increases in favorable attitudes and likelihood of approaching clients about concerning lesions with training. However, few studies have investigated the use of estheticians in skin cancer screening. OBJECTIVES: The objective of this study was to develop an education course to train estheticians to recognize concerning lesions, to assess the baseline knowledge of estheticians toward skin cancer detection, and to determine the effect that our curriculum has on lesion detection. METHODS: We administered an education course and corresponding cross-sectional surveys to estheticians to evaluate current knowledge and assess for improvements in attitudes and behaviors regarding skin cancer detection. RESULTS: Of 504 estheticians, most estheticians (85-98%) indicated the correct level of concern for "extremely concerning" lesions on pre- and post-training surveys. Estheticians were more likely to recommend that their client see a medical professional if they previously attended a course on skin cancer (p = 0.012) or had greater than 1 year of work experience (p < 0.001). After completion of the training module, most participants felt "very comfortable," suggesting that clients see a doctor for a suspicious lesion. CONCLUSION: Our findings suggest that estheticians are capable of indicating the appropriate level of concern for abnormal lesions. Estheticians may serve as a valuable screening partner for dermatologists in the detection of skin cancer.

Patients with Limited Life Expectancy Are Biopsied for Keratinocyte Cancers at Similar Frequency to Healthy Patients.

BACKGROUND: In many fields of medicine, guidelines recommend reduced cancer screening in patients of advanced age with limited life expectancy (LLE). In dermatology, there are currently no guidelines for adjusted evaluation and management practices of keratinocyte cancer (KC) in patients with LLE. Little is known regarding evaluation and management patterns and frequency of biopsies in these patients. OBJECTIVE: We sought to determine if dermatology providers biopsy LLE patients with similar frequency to their age-matched peers and quantify frequency of associated complications. METHODS: This was a retrospective cohort study of evaluations for skin cancer quantified by skin biopsy frequency at the North Texas Veterans Affairs Health System dermatology clinic for 3,062 patients between 2005 and 2009, including a 5-year follow-up period. Life expectancy was quantified by the validated Charlson Comorbidity Index (CCI) with a Deyo adaptation. RESULTS: There was no significant difference in biopsy frequency of KC in LLE versus non-LLE patients in most age-controlled groups, with increased biopsy frequency in LLE patients in the 65-74 age category (p = 0.02). There was also an increased risk of complications from biopsy in the 75-84 (many comorbidities subgroup: RR = 3.27, p = 0.002; some comorbidities subgroup: RR = 2.26, p = 0.048) and 65-74 (many comorbidities subgroup: RR = 1.52, p = 0.004) age groups when compared to age-matched healthy controls. CONCLUSION: Biopsy frequency is similar or increased in patients with LLE compared with age-matched controls, with increased frequency of complications. Further studies are needed to understand the underlying factors driving these practice patterns.

Use of Vasopressors in Extremely Preterm Infants in First Week of Life.

OBJECTIVE: A significant variability exists for diagnosis and treatment of hypotension in extremely preterm infants. Benefits of the use of vasopressors remain unclear. We wanted to identify the risk factors associated with use of vasopressors in the first week of life and their impact on outcomes of extremely preterm infants. STUDY DESIGN: Retrospective review of all newborns ≤28 weeks of gestational age (GA) admitted in neonatal intensive care unit from October 1, 2012, to October 31, 2015, done. Data regarding antenatal and neonatal characteristics and outcomes were recorded. Study infants were divided into two cohorts and compared based on vasopressor use. Chi-square, t-test, and multiple logistic regression were performed as appropriate and significance set at p <0.05. RESULTS: Of 213 extremely preterm infants, 90 (42.3%) received vasopressors in first week of life. The mean arterial pressure (MAP) at admission in these infants was significantly lower than that of infants who did not require vasopressors (27 ± 8 vs. 30 ± 6 mm Hg, p < 0.05). Vasopressors were initiated within 24 hours in 91% of babies. After controlling for other variables, use of vasopressors was significantly higher in infants with lower birth weight (odds ratio [OR]: 3.2, 95% confidence interval [CI]: 1.6-8.3), 5-minute Apgar's score ≤5 (OR: 1.8, 95% CI: 1.2-3.12), and admission hypothermia (OR: 2.7, 95% CI: 1.3-4.9). The use of vasopressors was significantly associated with severe intraventricular hemorrhage (IVH), even after controlling for other significant variables (OR: 5.9, 95% CI: 1.6-9.3). CONCLUSION: Lower birth weight, low 5-minute Apgar's score, and admission hypothermia are characteristics associated with early use of vasopressors in extremely preterm infants. Infants treated with vasopressors are at a higher risk of developing severe IVH. KEY POINTS: · Low systemic blood pressure is a very common problem in the extremely preterm population.. · In clinical practice, mean arterial blood pressure (BP) less than the infants GA in week is typically considered to be "low BP.". · About 50% of infants born at <29 weeks of GA received very preterm in the first week of life.. · Use of vasopressors is associated with a higher incidence of intraventricular hemorrhage in extremely preterm population..

The anatomy and histochemistry of flight hindlimb posture in birds. II. The flexed hindlimb posture of perching birds.

During flight, birds employ one of two hindlimb postures. Perching birds utilize a flexed posture with their folded legs tucked beneath the body, whereas shorebirds and raptors use an extended posture with straightened legs trailing behind the body. Maintenance of either posture during flight requires the hindlimbs to hold their position for prolonged periods. Slow contracting fibers are known for their fatigue-resistant properties and are often found in high percentages in muscles utilized for postural actions. Given the similar actions required of the hip and knee flexors used during flight, we hypothesized that the equivalent postural muscles of perching birds (flexed posture) would contain similar percentages of slow fibers as shorebirds (extended posture). We investigated the anatomy and fiber type composition of seven hindlimb muscles in yellow-headed and red-winged blackbirds and revealed that they possess a smaller percentage of slow fibers than we found previously in the same muscles of American avocets and black-necked stilts. The comparably smaller body size of yellow-headed and red-winged blackbirds could mitigate the need for more slow fibers. In addition, the biomechanical placement of the weight force in the flexed posture may require less muscle force for postural support during flight and, therefore, fewer slow fibers.

Major Device-Dependence of Measured Hypertensive Status From 24-Hour Ambulatory Blood Pressure Monitoring After Aortic Coarctation Repair.

BACKGROUND: Twenty-four-hour (24-hr) ambulatory blood pressure monitoring (ABPM) is often considered the gold standard to detect hypertension. We aimed to determine the short-term progression of 24-hour blood pressure after coarctation repair and to compare ABPM between two different devices. METHODS: We performed a cross-sectional study using 24-hour ABPM (Oscar 2) in 47 patients aged 16-48 years with previous paediatric coarctation repair and not on antihypertensive medication. Results were compared to a previous ABPM using paired analyses. A subset (10/47, 21%) had an additional previous ABPM performed using a Spacelabs device. RESULTS: After a mean follow-up of 27±6 years after repair, hypertension and prehypertension on Oscar 2 ABPM was present in 57% (27/47) and 11% (5/47), respectively. Mean follow-up time between Oscar 2 ABPMs was 3.9±1.4 years, and between first Oscar 2 and Spacelabs and between Spacelabs and second Oscar 2 ABPM was 1.4±0.8 and 1.8±0.3 years, respectively. There was no difference in the proportion of hypertensive patients between Oscar 2 ABPMs (55% [26/47] vs. 57% [27/47], p=1.0) but 17 patients (17/47, 36%) had a reclassification of 24-hour ABPM status. Mean 24-hour systolic blood pressure was higher in both Oscar 2 ABPMs compared to Spacelabs (142.4±11.7 vs. 120.4±11.8mmHg, p=0.0001; and 137.4±12.2 vs. 120.4±11.8mmHg, p=0.0001; respectively). CONCLUSION: There was high intra-device reproducibility of 24-hour ABPM results using an Oscar 2 device but poor inter-device reproducibility in patients with repaired coarctation. Device-specific reference values may be required to ensure reliable 24-hour ABPM interpretation.

Lifetime risk of end-stage kidney disease in living donors for paediatric kidney transplant recipients in Australia and New Zealand - a retrospective study.

Living kidney donors (LKD) for paediatric kidney transplant recipients (KTR) have a heightened motivation to donate for emotional reasons and the clear health benefits to the KTR. We hypothesized that the cohort of LKD for paediatric KTR (LKD-P) includes motivated young parents with a higher lifetime end-stage kidney disease (ESKD) risk compared to adult KTR (LKD-A). Data from the Australia and New Zealand Dialysis and Transplant LKD Registry (2004-2015) was analysed to compare baseline characteristics and predonation ESKD risk in LKD-P (n = 315) versus LKD-A (n = 3448). LKD-P were younger (median age 42 vs. 50 years; P < 0.001) and had a marginally higher lifetime ESKD risk (median 0.44% vs. 0.40%; P < 0.01), with a similar proportion of LKD exceeding 1% risk threshold (5.4% vs. 5.6%; P = NS). Compared to grandparents as LKD-P, parents (median age 41 vs. 59 years; P < 0.001) had a higher lifetime ESKD (0.44% vs. 0.25%; P < 0.001). Although unique benefits to paediatric KTR justify the minor increase in lifetime ESKD risk in young parents, carefully selected grandparents are an alternative LKD-P option, allowing parents to donate for subsequent transplants.

Application of an epitope-based allocation system in pediatric kidney transplantation.

Donor-recipient HLA mismatch remains a leading cause for sensitization and graft loss in kidney transplantation. HLA compatibility at an epitope level is emerging as an improved method of matching compared with current HLA antigen allocation. A novel epitope-based allocation approach to prospectively exclude donors with high-level mismatches was implemented for pediatric KTRs on the DD waiting list. Nineteen consecutive transplants were followed for 12 months, including eight DD KTRs listed with eplet exclusions, as well as three DD KTRs and eight LD KTRs without exclusions. KTRs with eplet exclusions had estimated GFR of 78.5 mL/min/1.73 m2 , no episodes of rejection, and time to transplant 6.55 months. HLA-A, HLA-B, HLA-DR antigen mismatches were similar between all groups. KTRs with exclusions had significantly lower class II eplet mismatches (20.4) than the contemporary DD KTRs without exclusions (63.7) and DD KTRs transplanted in the preceding decade (46.9). dnDSAs were identified in two of eight DD KTRs with exclusions, two of three DD KTRs without exclusions and five of eight LD KTRs. Epitope-based allocation achieved timely access to transplantation, low class II eplet mismatches, and low rates of dnDSAs in the first year. This strategy requires longer follow-up and larger numbers, but has the potential to reduce anti-HLA sensitization and improve both graft survival and opportunities for future retransplantation.

Socio-economic status and quality of life in children with chronic disease: A systematic review.

Reduced quality of life (QoL) is a known consequence of chronic disease in children, and this association may be more evident in those who are socio-economically disadvantaged. The aims of this systematic review were to assess the association between socio-economic disadvantage and QoL among children with chronic disease, and to identify the specific socio-economic factors that are most influential. MEDLINE, Embase and PsycINFO were searched to March 2015. Observational studies that reported the association between at least one measure of social disadvantage in caregivers and at least one QoL measure in children and young people (age 2-21 years) with a debilitating non-communicable childhood disease (asthma, chronic kidney disease, type 1 diabetes mellitus and epilepsy) were eligible. A total of 30 studies involving 6957 patients were included (asthma (six studies, n = 576), chronic kidney disease (four studies, n = 796), epilepsy (14 studies, n = 2121), type 1 diabetes mellitus (six studies, n = 3464)). A total of 22 (73%) studies reported a statistically significant association between at least one socio-economic determinant and QoL. Parental education, occupation, marital status, income and health insurance coverage were associated with reduced QoL in children with chronic disease. The quality of the included studies varied widely and there was a high risk of reporting bias. Children with chronic disease from lower socio-economic backgrounds experience reduced QoL compared with their wealthier counterparts. Initiatives to improve access to and usage of medical and psychological services by children and their families who are socio-economically disadvantaged may help to mitigate the disparities and improve outcomes in children with chronic illnesses.

Clinical Characteristics Associated with Musculoskeletal Extracutaneous Manifestations in Pediatric and Adult Morphea: A Prospective, Cohort Study.

Morphea is an autoimmune condition of the skin associated with functional sequelae resulting from musculoskeletal involvement. Systematic investigation of risk for musculoskeletal involvement is limited, particularly in adults. This knowledge gap impairs patient care because practitioners are unable to risk stratify patients. To address this gap, we determined the frequency, distribution, and type of musculoskeletal (MSK) extracutaneous manifestations affecting joint and bone with overlying morphea lesions using cross-sectional analysis of 1,058 participants enrolled in two prospective cohort registries (Morphea in Children and Adults Cohort [n = 750] and National Registry for Childhood Onset Scleroderma [n = 308]). Additional analysis included the identification of clinical features associated with MSK extracutaneous manifestations. MSK extracutaneous manifestations occurred in 274 of 1,058 participants (26% overall, 32% pediatric, and 21% adults). Children had a limited range of motion of larger joints (i.e., knees/hips/shoulders), whereas the involvement of smaller joints (i.e., toes/temporomandibular joint) was more common in adults. Multivariable logistic regression showed that deep tissue involvement had the strongest association with musculoskeletal features, with a lack of deep tissue involvement having a negative predictive value of 90% for MSK extracutaneous manifestations. Our results underscore the need to evaluate MSK involvement in adult and pediatric patients and the utility of using depth of involvement in addition to anatomic distribution to risk stratify patients.
