Implementation of a Perinatal Hospice Program
Authors: Falke Megan , Rubarth Lori Baas 
Published: May 2020

Background:
In 2017, the Nebraska Unicameral passed legislative bill 506, which required physicians to inform patients carrying fetuses diagnosed with a life-limiting anomaly of the option to enroll in a comprehensive perinatal hospice program. The bill also required the Department of Health & Human Services to provide information about statewide hospice programs. Families enrolled in hospice programs are better prepared for the birth and death of their child. This large academic medical center was listed on the registry but did not have a formal perinatal hospice program.

Purpose:
Implementation of a comprehensive perinatal hospice program.

Methods:
The program was designed and implemented, beginning with the formation of an interdisciplinary team. Guidelines were developed for program referral, care conferences, team communication, and family follow-up. The team was educated. Electronic record documentation and order set were implemented. A data collection process was developed to track referrals and critical data points.

Results:
The perinatal hospice program has been accepting referrals but has not had any qualifying referrals.

Implications for Practice:
The development of an evidence-based guideline for referral that can improve referral consistency. While trisomy 13 and 18 diagnosis was historically considered life-limiting, these families now have the option of full intervention and transfer for specialists.

Implications for Research:
Future research will include collecting data from patients who could have benefited from hospice, including infants who were born 20 to 22 weeks, or for maternal reasons. Future research will evaluate the experience after bereavement, the hospice team's experience, and the effectiveness of the referral process.

OBJECTIVE:
To estimate alcohol, tobacco, and recreational drug use during pregnancy among nulliparous women.

METHODS:
In a cohort of nulliparous women followed through pregnancy from the first-trimester nuMoM2b (Nulliparous Outcomes in Pregnancy: Monitoring Mothers to be) study, self-reported use of alcohol, tobacco, and drugs was chronicled longitudinally at four study visits in this secondary analysis. Rates of use before pregnancy, in each trimester (visit 1, visit 2, visit 3, approximating each trimester), and at the time of delivery (visit 4) were recorded. The amount of alcohol, tobacco, and drug exposure were recorded using validated measures, and trends across pregnancy were analyzed.

RESULTS:
Of the 10,038 study participants, 10,028 had information regarding alcohol, tobacco, and drug use at visit 1, 9,412 at visit 2, 9,217 at visit 3, and 7,167 at visit 4. The rates of drinking alcohol, which had been 64.6% in the 3 months before pregnancy, were lower in pregnancy (3.9% at visit 1, 5.6% at visit 2, 7.0% at visit 3, and 6.1% at visit 4, P<.001 for all). Rates later in pregnancy were all greater than in the first trimester (P<.01). The rate of smoking in the 3 months before pregnancy, which was 17.8%, also declined at visit 1 (5.9%), and continued to decline through pregnancy (5.3% at visit 2, 4.7% at visit 3, and 3.9% at visit 4, with all rates lower than that of visit 1 [P<.01]). Although recreational drug use was relatively common in the months before pregnancy (33.8%), it also declined during pregnancy (1.1% at visit 2, 0.7% at visit 3, 0.4% at visit 4).

CONCLUSIONS:
In this geographically and ethnically diverse cohort of nulliparous women, rates of self-reported alcohol, smoking, and recreational drug use were all significantly lower during than before pregnancy. Nonetheless, rates of alcohol use rose as pregnancy progressed, highlighting the need for continued counseling throughout all trimesters of pregnancy.

Authors: Ushida Takafumi , Kotani Tomomi , Sadachi Ryo , Hirakawa Akihiro , Hayakawa Masahiro , Moriyama Yoshinori , Imai Kenji , Nakano-Kobayashi Tomoko , Kikkawa Fumitaka ,   for the Neonatal Research Network of Japan
Published: May 2020

OBJECTIVE:
To estimate whether improvement in outcomes from antenatal corticosteroid treatment in extremely and very preterm twins is similar to that observed in singletons, and to investigate whether antenatal corticosteroid treatment has different effects according to chorionicity or birth order.

METHODS:
This population-based study was based on an analysis of data collected by the Neonatal Research Network of Japan from 2003 to 2015 of neonates weighing 1,500 g or less at birth, from gestational ages of 24 0/7 to 31 6/7 weeks of gestation. After propensity score matching, univariate logistic and interaction analyses were performed to compare short-term (neonatal period) and medium-term (3 years of age) outcomes of the children of mothers who received antenatal corticosteroids with those of children of mothers who did not receive antenatal corticosteroids. We focused on differences between singletons and twins, between monochorionic and dichorionic twins and between the first and second twin.

RESULTS:
The study comprised 23,502 singletons and 6,546 twins. Antenatal corticosteroid treatment was associated with significant decreased short-term neurologic outcomes in both singletons and twins. However, antenatal corticosteroid treatment was associated with significantly decreased mortality (odds ratio [OR] 0.61; 95% CI 0.53–0.70), respiratory distress syndrome (OR 0.71, 95% CI 0.67–0.76), and cerebral palsy (OR 0.85, 95% CI 0.72–0.99) in singletons but not in twins (OR 0.89, 95% CI 0.68–1.17; OR 0.99, 95% CI 0.87–1.12; and OR 0.82, 95% CI 0.61–1.11, respectively). No association was found between chorionicity and the efficacy of antenatal corticosteroid treatment on outcomes. Further, no association was found between birth order and the efficacy of antenatal corticosteroid treatment on outcomes, except for periventricular leukomalacia and necrotizing enterocolitis (interaction: P=.02 and P=.04, respectively).

CONCLUSION:
Antenatal corticosteroid treatment in twins was associated with a beneficial effect on short-term neurologic outcomes only, without improvement in other short-term and medium-term outcomes. There was no difference related to chorionicity.
Traumatic Hip Fracture and Primary Elective Total Hip Patients are Not the Same: A Comparison of Comorbidity Burden, Hospital Course, Postoperative Complications, and Cost of Care Analysis
Authors: Lowe Jason , Mitchell Sean M. , Agarwal Sumit , Jones Clifford B. 
Published: May 2020

Objectives:
To compare patient admission comorbidity profiles, length of stay, readmission rate, postoperative complications, mortality rate, and cost of care between acute geriatric hip fractures (HF) and elective total hip arthroplasties (THA).

Methods:
Retrospective cohort.

Setting:
Multicenter health care system.

Patients:
Eighteen thousand forty-two geriatric HF treated with operative fixation or arthroplasty and 8761 elective total hip patients were reviewed.

Main Outcome Measurements:
Charlson Comorbidity Index, length of stay, ICU admission, readmission rate, postoperative complications, mortality rates, and cost of care.

Results:
Medical comorbidities: chronic pulmonary disease, chronic kidney disease, coronary artery disease, heart failure, liver cirrhosis, and cerebrovascular disease were higher in HF patients as was mean Charlson Comorbidity Index (P < 0.001). Albumin was lower and HgbA1c higher in HF patients (P < 0.001). Average length of stay was 5.0 versus 2.6 days (P < 0.001) with 8.5% of HF patients being managed in the ICU versus 1.8% of THA patients. Readmission rates for HF and THA patients were 21.4% and 6.2%, respectively (P < 0.001). Minor and major complications were higher in the HF cohort (P < 0.001), as were 30-day (1.97% vs. 0.17%) and 1-year mortality rates (3.49% vs. 0.40%) (P < 0.001). Mean hospital cost of care was nearly 15,000 US dollars more expensive in HF patients when compared to the elective THA cohort (P < 0.001).

Conclusions:
HF patients have increased comorbidity burdens, lengths of stay, ICU admissions, readmission rates, complications, mortality, and costs of care than patients with elective total hip arthroplasty. In the era of pay for quality performance, health systems must reconcile the difference between these 2 patient cohorts.

Increased Microvessel and Arteriole Density in the Contracted Side of the Relapsed Clubfoot
Authors: Novotny Tomas , Eckhardt Adam , Knitlova Jarmila , Doubkova Martina , Ostadal Martin , Uhlik Jiri , Musilkova Jana 
Published: May 2020

Background:
Clubfoot deformity (pes equinovarus) is one of the most common birth defects, and its etiology is still unknown. Initial clubfoot treatment is based on the Ponseti method throughout most of the world. Despite the effectiveness of this therapy, clubfoot may relapse. Recent studies confirm the theory of active fibrotic remodeling processes in the extracellular matrix of the affected tissue. The aim of this study was to clarify whether relapses in clubfoot therapy are associated with altered angiogenesis and to suggest possible regulatory pathways of this pathologic process.

Methods:
We compared microvessel density, arteriole density, and concentration of angioproliferative-related proteins found between tissues in the contracted, that is, the medial side (M-side), and noncontracted, that is, the lateral side (L-side) of the relapsed clubfeet. Tissue samples from 10 patients were analyzed. Histopathologic analysis consisted of immunohistochemistry and image analysis. Real-time polymerase chain reaction was used to study mRNA expression.

Results:
An increase in microvessel and arteriole density was noted in contracted, relapsed clubfoot tissue. This was accompanied by a significant increase in the levels of the vascular endothelial growth factor, vascular endothelial growth factor receptor 2, β catenin and active β catenin. Vascular endothelial growth factor, vascular endothelial growth factor receptor 2, and CD31 overexpression was also seen with mRNA analysis.

Conclusions:
Increased microvessel and arteriole density in the contracted side of the relapsed clubfoot was noted. These processes are mediated by specific proangiogenic proteins that are overexpressed in the contracted tissue. These findings contribute to the etiology and the development of relapses in the treatment of clubfoot.

Intraoperative Prone Radiographs During Scheuermann Kyphosis Correction Closely Estimate Standing Thoracic and Lumbar Parameters at 2 Years
Authors: Greenhill Dustin A. , Poppino Kiley F. , Jo Chan-Hee , Sucato Daniel J. 
Published: May 2020

Background:
In patients with Scheuermann kyphosis (SK) undergoing posterior spinal fusion with instrumentation (PSFI), intraoperative lateral radiographs assess deformity correction in the prone position. The relationship between thoracic and (partially un-instrumented) lumbar parameters on prone intraoperative versus standing postoperative radiographs is unknown.

Methods:
Forty-five consecutive patients with SK who underwent PSFI between 2007 and 2014 were reviewed. Thoracic kyphosis (TK), lumbar lordosis (LL), instrumented level kyphosis [upper instrumented vertebrae (UIV)-lower instrumented vertebrae (LIV)], and traditional sagittal parameters were recorded from preoperative standing, intraoperative prone, first outpatient standing, and >2-year standing radiographs and time periods were compared. Exclusion criteria included reduction modification after intraoperative radiographs and postoperative construct revision prohibiting comparison to initial intraoperative radiographs.

Results:
Twenty-five patients averaging 16 (12 to 20) years old during surgery with 3.1 (2 to 7) years follow-up met inclusion criteria. Average surgical variables included: 13±1 fusion levels, UIV at T2, LIV at L3, 3.8±1.6 osteotomies per patient, and 43±9% correction of TK. Preoperative TK and LL measured 82 and 76 degrees, respectively. TK on intraoperative (47 degrees), 6-week (49 degrees), and >2-year (50 degrees) radiographs changed significantly only between intraoperative and >2-year radiographs (P=0.03) by just 3 degrees. LL increased 5 degrees from intraoperative prone to 6-week standing radiographs (51 to 56 degrees, P=0.01) without further significant change at >2 years (59 degrees, P=0.09). Instrumented levels (UIV-LIV) had increased kyphosis at 6 weeks (32 to 35 degrees, P=0.01) without further change at >2 years (36 degrees, P=0.06).

Conclusions:
TK on intraoperative prone radiographs during PSFI for SK should match the standing TK ∼6 weeks later. Intraoperative prone LL only slightly increases on early standing radiographs. Assuming a routine postoperative course, intraoperative radiographs slightly underestimate TK (by 3 degrees) and LL (by 8 degrees) on >2-year standing radiographs. These parameters (TK, LL, UIV-LIV) are visualized during surgery and should be used in future studies to predict long-term outcomes.

Level IV—retrospective study.
Modified Woodward Technique for Sprengel Deformity and a Modification of the Cavendish Classification
Authors: Öner Ali , Köksal Alper , Çimen Osman , Kargin Deniz , Albayrak Akif , Akman Yunus E. 
Published: May 2020

Introduction:
Sprengel deformity (SD) is the most common congenital anomaly of the shoulder. Surgery is required for moderate and severe forms. The modified Woodward procedure is the most widely used procedure for the surgical treatment.

Methods:
SD patients who applied to our institution between 2005 and 2018 were retrospectively reviewed. A modification of the Cavendish classification was used for preoperative and postoperative evaluations.

Results:
Eighteen shoulders of 17 (mean age: 8.5 y, range: 2 to 18 y, 5 males and 12 females) patients were included. The right, left, and bilateral shoulders were affected in 9, 7, and 1 cases, respectively. The mean follow-up time was 62.9 months (12 to 161 mo). Preoperatively, 3 shoulders were type 2, 12 shoulders were type 3, and 3 shoulders were type 4 according to the Cavendish classification and 2 shoulders were type 0, 6 shoulders were type 1, and 10 shoulders were type 2 postoperatively.

Conclusions:
Periscapular congenital malformations play a significant role in range of motion limitation. The modified Woodward procedure is a viable alternative in the surgical treatment of SD and the proposed modification of Cavendish classification (grade 0) is functional.

Authors: Dragsted Casper , Fruergaard Sidsel , Jain Mohit J. , Deveza Lorenzo , Heydemann John , Ohrt-Nissen Søren , Andersen Thomas , Gehrchen Martin , Dahl Benny 
Published: May 2020

Background:
Consensus is lacking regarding the lengthening procedures in magnetically controlled growing rods (MCGR), and no studies have compared the outcome between different distraction principles. The purpose of the present study was to compare distraction-to-stall with targeted distraction and identify variables associated with achieved distraction.

Methods:
We performed a 2-center retrospective study of all children treated with MCGR from November 2013 to January 2019, having a minimum of 1-year follow-up and undergoing a minimum of 3 distractions. Exclusion criteria were single-rod constructs and conversion cases. In group 1 (21 patients), we used a distraction-to-stall (maximum force) principle where each rod was lengthened until the internal magnetic driver stopped (clunking). In group 2 (18 patients), we used a targeted distraction principle, where the desired distraction was entered the remote control before distraction. In both groups we aimed for maximal distraction and curve correction at index surgery. Achieved distraction was measured on calibrated radiographs and compared between the 2 groups using a linear mixed effects model. Univariate and multivariate analyses were performed to identify variables associated with achieved distraction within the first year.

Results:
Mean age at surgery was 9.5±2.0 years. Etiology of the deformity was congenital/structural (n=7), neuromuscular (n=9), syndromic (n=3), or idiopathic (n=20). Demographics and preoperative characteristics including spinal height (T1T12 and T1S1) did not differ significantly between the groups (P≥0.13). Time interval between distractions were mean 18 days (95% confidence interval: 10-25) shorter in group 1. Implant-related complications occurred in 10/39 patients, 5 in each group. We found no difference in achieved distraction between the groups in the linear mixed effects model. In the multivariate analysis, preoperative major curve angle was the only independent variable associated with achieved distraction.

Conclusions:
In 2 comparable and consecutive cohorts of patients treated with MCGR, we found no difference in achieved distraction between a distraction-to-stall and a targeted distraction principle. Preoperative major curve angle was the only independent predictor of achieved distraction.

Level of Evidence:
Level III—retrospective comparative study.
Clinicopathological Features of Seborrheic-Like Dermatitis in HIV-Infected Adults: A Single Institutional Descriptive Cross-Sectional Study
Authors: Mahlangeni Gcina M. , Tod Bianca M. , Jordaan Hendry Francois , Schneider Johann W. 
Published: May 2020

Background:
Atypical and severe clinical presentations of seborrheic-like dermatitis (SLD) are associated with HIV infection, correlating with advanced disease or low CD4 counts. Previous studies documented histological findings characteristic of seborrheic dermatitis in HIV-positive patients.

Objective:
To expand current knowledge of the clinicopathological characteristics of SLD in South African HIV-seropositive individuals.

Methods:
This prospective study included HIV-seropositive adult patients presenting with SLD to a dermatology clinic from March 2017 to April 2018. A dermatologist established the diagnosis of SLD and the severity of the disease. Detail about antiretroviral therapy (ART), the latest CD4 count, and the viral load was retrieved from the patients' clinical records. Histopathological assessment of the patients' skin biopsies was recorded using standardized data sheets and semiquantifiable grades.

Results:
This study included 13 women and 17 men. Fifty percent of patients showed severe or very severe SLD. Six (20.0%) patients presented with erythroderma. Statistical analysis did not show a significant correlation between severity of disease and CD4 count, viral load, or ART, respectively. This study confirmed that the presence of confluent parakeratosis, necrotic keratinocytes, plasma cells, neutrophils with leukocytoclasia, and leukoexocytosis are histopathological clues to SLD occurring in HIV-seropositive patients.

Conclusion:
SLD in HIV patients may present with varying clinical severity, including erythroderma. The association between the prevalence and severity of SLD with CD4 count, viral load, and ART requires further studies with larger patient populations. The presence of specific histopathological features in a skin biopsy of SLD is a clue to the diagnosis of HIV.
Plasma YKL-40 as a biomarker in patients with nonmetastatic bone and soft tissue sarcomas: a prospective exploratory clinical study
Authors: Thorn Andrea P. , Harving Mette L. , Lausten Gunnar S. , Johansen Julia S. , Sørensen Michala S. , Petersen Michael M. 
Published: May 2020

Purpose:
YKL-40 is a glycoprotein with a role in inflammation, tissue remodeling, tumor angiogenesis, and protection against apoptosis. We hypothesized that high preoperative plasma YKL-40 in patients with nonmetastatic bone and soft tissue sarcoma (STS) is associated with short overall survival (OS), and that plasma YKL-40 is an independent predictor for OS.

Materials and methods:
Plasma was collected preoperatively from 65 patients with nonmetastatic bone (n=14) or STS (n=51) in the lower extremities (n=43), the upper extremities (n=16) or the trunk wall/spine (n=6). All patients underwent surgical cancer treatment. Twenty patients developed metastases during the follow-up period (minimum 5 y). The plasma concentration of YKL-40 was determined by enzyme-linked immunosorbent assay.

Results:
Twenty-seven patients died [mean: 3.2 (range: 0.2–7.3) y postoperatively] and 38 patients were still alive after a follow-up of mean 6.9 (5.8–8.2) years postoperatively. Plasma YKL-40 was higher in patients who died during follow-up (P=0.008), in males (P=0.007) and in patients 61 years of age and above (P=0.001).
The 5-year OS was 68% and OS was lower in patients with high (≥95% percentile age-corrected) plasma YKL-40 (P=0.021), age 61 years and above (P=0.013), high histologic malignancy grade (P=0.047) and male sex (P=0.051). Multivariable analysis showed that only plasma YKL-40 (age-corrected (hazard ratio=2.80, 95% confidence interval: 1.13–6.91, P=0.026) and malignancy grade (hazard ratio=9.9×107, 95% confidence interval: 0–∞, P=0.007) remained independent prognostic factors for OS.

Conclusions:
High preoperative plasma YKL-40 was related to short OS in patients with nonmetastatic bone and STS and plasma YKL-40 (age-corrected) was an independent prognostic risk factor for OS.
Comparison of the Progression of Localized Retinal Nerve Fiber Layer Defects in Red-free Fundus Photograph, En Face Structural Image, and OCT Angiography Image
Authors: Ji Min Jung , Park Ji-Hye , Yoo Chungkwon , Kim Yong Yeon 
Published: May 2020

Precis:
This study demonstrated the high topographic correlation between the red-free fundus photographs and en face structural images in eyes with glaucomatous progression.

Purpose:
The purpose of this study was to compare the progression of localized retinal nerve fiber layer (RNFL) defects in red-free fundus photographs, en face structural images, and optical coherence tomography angiography (OCTA) images.

Methods:
We performed a retrospective, comparative study on 45 glaucomatous eyes showing RNFL defect widening in red-free photography. The localized RNFL defect in the red-free photographs was termed as red-free defect. The wedge-shaped hyporeflective area radiating from the optic nerve head in the optical coherence tomography (OCT) en face structural images and OCTA images was defined as en face defect and OCTA defect, respectively. The baseline and follow-up angular parameters of each red-free defect were compared with those of en face defect and OCTA defect.

Results:
When the baseline angular parameters were compared, there were no significant differences between red-free defect and en face defect, and between red-free defect and OCTA defect (all, P>0.017). In addition, the follow-up angular parameters showed no difference between red-free defect and en face defect. However, the OCTA defect showed significantly greater values compared with red-free defect and en face defect with respect to the distal angular location and angular width at follow-up visit (36.78±15.10 vs. 34.10±15.09 vs. 33.40±15.05 degrees, both, P<0.001).

Conclusions:
Localized RNFL defects detected in red-free photographs showed high topographic correlation with defects detected in OCT en face structural images, and this correlation was also noted in eyes with progressive glaucoma. The OCT en face structural images may be an alternative to red-free photography for identifying progressive RNFL defects in eyes with glaucoma.
