Summary: Large abdominal wall and groin defects present complex reconstructive challenges. These defects typically require free flap reconstruction to bring in healthy vascularized tissue and recreate the complex full-thickness defect. A 6-year-old previously healthy girl presented to our trauma center after sustaining a close-range shotgun injury resulting in a full-thickness defect to the inferior hemi-abdomen and groin. A composite anterolateral thigh flap with fascia lata free flap was performed to reconstruct the myofascial, skin, and subcutaneous tissue of the abdomen and groin. We present the first composite anterolateral thigh flap with fascia lata for full-thickness abdominal wall and groin reconstruction in a pediatric patient.

Abstract BACKGROUND Dyslipoproteinemias can be classified by their distinct lipoprotein patterns, which helps determine atherosclerotic cardiovascular disease (ASCVD) risk and directs lipid management but this has required advanced laboratory testing. OBJECTIVE To develop a new algorithm for classifying lipoprotein disorders that only relies on the standard lipid panel. METHODS Lipid thresholds for defining the different lipoprotein phenotypes were derived for Non-High-Density Lipoprotein-Cholesterol (NonHDL-C) and Triglycerides (TG) to be concordant when possible with the current US Multi-Society guidelines for blood cholesterol management. RESULTS The new classification method categorizes patients into all the classical Fredrickson-like phenotypes except for Type III dysbetalipoproteinemia. In addition, a new hypolipidemic phenotype (Type VI) due to genetic mutations in apoB-metabolism is described. The validity of the new algorithm was confirmed by lipid analysis by NMR (N = 11,365) and by concordance with classification by agarose gel electrophoresis/beta-quantification (N = 5504). Furthermore, based on the Atherosclerosis Risk in Communities (ARIC) cohort (N = 14742), the lipoprotein phenotypes differ in their association with ASCVD (TypeV > IIb > IVb > IIa > IVa > normolipidemic) and can be used prognostically as risk enhancer conditions in the management of patients. CONCLUSIONS We describe a clinically useful lipoprotein phenotyping system that is only dependent upon the standard lipid panel. It, therefore, can be easily implemented for increasing compliance with current guidelines and for improving the care of patients at risk for ASCVD.

SummaryIn young and fit patients with mantle cell lymphoma (MCL), intensive induction therapy followed by a consolidative autologous haematopoietic cell transplant (autoHCT) is the standard of care in the front‐line setting. Recently, time‐to‐event analysis has emerged as an important risk assessment tool in lymphoma, though its impact in MCL is not well defined. We utilized the Center for International Blood and Marrow Transplant Research database to evaluate the effect of post‐autoHCT time to relapse on overall survival (OS) over time in 461 patients who underwent autoHCT within 12 months of MCL diagnosis. On multivariate analysis, the impact of relapse on OS was greatest at the six‐month [hazard ratio (HR) = 7·68], 12‐month (HR = 6·68), and 18‐month (HR = 5·81) landmark timepoints. Using a dynamic landmark model we demonstrate that adjusted OS at five years following each landmark timepoint improved with time for relapsing and non‐relapsing patients. Furthermore, early relapse (<18 months) following autoHCT defines a high‐risk group with inferior post‐relapse OS. This retrospective analysis highlights the impact of time to relapse on OS in MCL patients undergoing up‐front autoHCT and emphasizes the need to consider novel therapeutic approaches for patients suffering early relapse.

Abstract The role of haploidentical hematopoietic cell transplantation (HCT) using posttransplant cyclophosphamide (PTCy) for acute lymphoblastic leukemia (ALL) is being defined. We performed a retrospective, multivariable analysis comparing outcomes of HCT approaches by donor for adults with ALL in remission. The primary objective was to compare overall survival (OS) among haploidentical HCTs using PTCy and HLA-matched sibling donor (MSD), 8/8 HLA-matched unrelated donor (MUD), 7 /8 HLA-MUD, or umbilical cord blood (UCB) HCT. Comparing haploidentical HCT to MSD HCT, we found that OS, leukemia-free survival (LFS), nonrelapse mortality (NRM), relapse, and acute graft-versus-host disease (aGVHD) were not different but chronic GVHD (cGVHD) was higher in MSD HCT. Compared with MUD HCT, OS, LFS, and relapse were not different, but MUD HCT had increased NRM (hazard ratio [HR], 1.42; P = .02), grade 3 to 4 aGVHD (HR, 1.59; P = .005), and cGVHD. Compared with 7/8 UD HCT, LFS and relapse were not different, but 7/8 UD HCT had worse OS (HR, 1.38; P = .01) and increased NRM (HR, 2.13; P ≤ .001), grade 3 to 4 aGVHD (HR, 1.86; P = .003), and cGVHD (HR, 1.72; P ≤ .001). Compared with UCB HCT, late OS, late LFS, relapse, and cGVHD were not different but UCB HCT had worse early OS (≤18 months; HR, 1.93; P &lt; .001), worse early LFS (HR, 1.40; P = .007) and increased incidences of NRM (HR, 2.08; P &lt; .001) and grade 3 to 4 aGVHD (HR, 1.97; P &lt; .001). Haploidentical HCT using PTCy showed no difference in survival but less GVHD compared with traditional MSD and MUD HCT and is the preferred alternative donor HCT option for adults with ALL in complete remission.

Cyclospora cayetanensis is an intestinal coccidian parasite transmitted to humans through the consumption of oocysts in fecally contaminated food and water. Infection is found worldwide and is highly endemic in tropical and subtropical regions with poor sanitation. Disease in developed countries is usually observed in travelers and in seasonal outbreaks associated with imported produce from endemic areas. Recently, summertime outbreaks in the United States have also been linked to locally grown produce. Cyclosporiasis causes a diarrheal illness which may be severe in infants, the elderly, and immunocompromised individuals. The increased adoption of highly sensitive molecular diagnostic tests, including commercially available multiplex panels for gastrointestinal pathogens, has facilitated the detection of infection and likely contributed to the increased reports of cases in developed countries. This manuscript reviews important aspects of the biology, epidemiology, and clinical manifestations of C. cayetanensis and provides an in-depth discussion of current laboratory diagnostic methods.

Purpose Clinical trials have demonstrated that standardized voice treatment programs are effective for some patients, but identifying the unique individual treatment ingredients specifically responsible for observed improvements remains elusive. To address this problem, the authors used a taxonomy of voice therapy, the Rehabilitation Treatment Specification System (RTSS), and a Delphi process to develop the RTSS-Voice (expert consensus categories of measurable and unique voice treatment ingredients and targets). Method Initial targets and ingredients were derived from a taxonomy of voice therapy. Through six Delphi Rounds, 10 vocal rehabilitation experts rated the measurability and uniqueness of individual treatment targets and ingredients. After each round, revisions (guided by the experts' feedback) were finalized among a primary reader (a voice therapy expert) and two external readers (rehabilitation experts outside the field of voice). Consensus was established when the label and definition of an ingredient or target reached a supramajority threshold (≥ 8 of 10 expert agreement). Results Thirty-five target and 19 ingredient categories were agreed to be measurable, unique, and accurate reflections of the rules and terminology of the RTSS. Operational definitions for each category included differences in the way ingredients are delivered and the way individual targets are modified by those ingredients. Conclusions The consensus labels and operationalized ingredients and targets making up the RTSS-Voice have potential to improve voice therapy research, practice, and education/training. The methods used to develop these lists may be useful for other speech, language, and hearing treatment specifications. Supplemental Material https://doi.org/10.23641/asha.15243357
