Associations of a Prenatal Serum Per- and Polyfluoroalkyl Substance Mixture with the Cord Serum Metabolome in the HOME Study.

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous and persistent chemicals associated with multiple adverse health outcomes; however, the biological pathways affected by these chemicals are unknown. To address this knowledge gap, we used data from 264 mother-infant dyads in the Health Outcomes and Measures of the Environment (HOME) Study and employed quantile-based g-computation to estimate covariate-adjusted associations between a prenatal (∼16 weeks' gestation) serum PFAS mixture [perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexanesulfonic acid (PFHxS), and perfluorononanoic acid (PFNA)] and 14,402 features measured in cord serum. The PFAS mixture was associated with four features: PFOS, PFHxS, a putatively identified metabolite (3-monoiodo-l-thyronine 4-O-sulfate), and an unidentified feature (590.0020 m/z and 441.4 s retention time; false discovery rate <0.20). Using pathway enrichment analysis coupled with quantile-based g-computation, the PFAS mixture was associated with 49 metabolic pathways, most notably amino acid, carbohydrate, lipid and cofactor and vitamin metabolism, as well as glycan biosynthesis and metabolism (P(Gamma) <0.05). Future studies should assess if these pathways mediate associations of prenatal PFAS exposure with infant or child health outcomes, such as birthweight or vaccine response.

Evaluation of health service outcomes for an audiology first point of contact retrocochlear clinic: a 6-year retrospective cohort study.

OBJECTIVE: Although existing studies of audiology first point of contact clinics which screen for retrocochlear pathology have demonstrated positive clinical outcomes, they have provided limited information regarding service impacts. Thus, this study aimed to evaluate both the clinical and health service outcomes of an audiology first point of contact (FPOC) clinic for adults referred to ENT services with suspected retrocochlear pathology. DESIGN: Retrospective cohort study. STUDY SAMPLE: All 1123 patients referred to the clinic over a 6-year period (2013-2019). RESULTS: Most (73.7%) of the 1123 patients referred to the Retrocochlear Clinic were managed and discharged by the audiologist and did not require ENT appointment. Almost half (43.1%) were directly referred for MRI imaging, of which 4 (1.1%) were diagnosed with Vestibular Schwannoma. Waiting times for first appointments significantly (p < 0.001) reduced from a median of 748 days to 63.5 days over the 6-year period. Attendance rates also significantly (p < 0.001) improved over this time (from 52.2% to 90%). There were no adverse events reported. Of those discharged without attending an ENT appointment, 1.8% were rereferred to ENT within 12 months of discharge. CONCLUSIONS: This audiology FPOC Retrocochlear Clinic was shown to be a safe and effective alternative service model.

Prenatal organophosphorus pesticide exposure and executive function in preschool-aged children in the Norwegian Mother, Father and Child Cohort Study (MoBa).

INTRODUCTION: Prenatal exposure to organophosphorus pesticides (OPPs) has been associated with neurodevelopmental deficits in children, however evidence linking OPPs with specific cognitive mechanisms, such as executive function (EF), is limited. OBJECTIVE: This study aims to evaluate the association between prenatal exposure to OPPs with multiple measures of EF in preschool-aged children, while considering the role of variant alleles in OPP metabolism genes. METHODS: We included 262 children with preschool attention-deficit/hyperactivity disorder (ADHD), and 78 typically developing children, from the Preschool ADHD substudy of the Norwegian, Mother, Father, and Child Cohort Study. Participants who gave birth between 2004 and 2008 were invited to participate in an on-site clinical assessment when the child was approximately 3.5 years; measurements of EF included parent and teacher rating on Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P), and three performance-based assessments. We measured OPP metabolites in maternal urines collected at ∼17 weeks' gestation to calculate total dimethyl- (ΣDMP) and diethyl phosphate (ΣDEP) metabolite concentrations. We estimated multivariable adjusted ß's and 95% confidence intervals (CIs) corresponding to a change in z-score per unit increase in log-ΣDMP/DEP. We further characterized gene-OPP interactions for maternal variants in PON1 (Q192R, M55L), CYP1A2 (1548T > C), CYP1A1 (IntG > A) and CYP2A6 (-47A > C). RESULTS: Prenatal OPP metabolite concentrations were associated with worse parent and teacher ratings of emotional control, inhibition, and working memory. A one log-∑DMP increase was associated with poorer teacher ratings of EF on the BRIEF-P (e.g. emotional control domain: ß = 0.55, 95% CI: 0.35, 0.74), when weighted to account for sampling procedures. We found less consistent associations with performance-based EF assessments. We found some evidence of modification for PON1 Q192R and CYP2A6 -47A > C. Association with other variants were inconsistent. CONCLUSIONS: Biomarkers of prenatal OPP exposure were associated with more adverse teacher and parent ratings of EF in preschool-aged children.

Construction of Femoral Vessel Nomograms for Planning Cardiac Interventional Procedures in Children 0-4 Years Old.

The objectives of this study were to construct femoral artery (FA) and femoral vein (FV) nomograms in children aged 0-4 years and to construct probability curves for the occurrence of arterial access complications based on the size of the FA. The FV and FA are commonly accessed during cardiac catheterizations in children with congenital heart diseases (CHD). However, nomograms for vessel dimensions based on child's age or size are not available. This knowledge may be helpful for interventional planning. A prospective study was performed on 400 children (age 0-4 years) with CHD undergoing cardiac catheterizations over a 3-year period. Ultrasound evaluation of the right and left FA and FV was performed under anesthesia prior to vascular access. Regression modeling was applied to derive nomograms based on quantile polynomial regression, which yielded good fit to the data judged by R-squared. GAMLSS transformation method was used to formulate smoothed percentiles. A separate prospective evaluation of FA to determine the size below which loss of pulse (LOP) are likely to occur was performed. Nomograms for FA and FV diameter and cross-sectional area against age and body surface area and probability curves for FA LOP were constructed. It is now possible to examine ultrasound-based normal sizes of femoral vein and artery in children 0-4 years of age. Femoral vessel nomograms and LOP probability curves may help with interventional planning. Future studies with larger sample size, including children of other ages may be useful.

Physical Therapy Outcome Measures for Assessment of Lower Extremity Chronic Pain-Related Function in Pediatrics.

PURPOSE: To assess the clinical utility of 5 physical therapy (PT) outcome measures in quantifying functional changes in pediatric lower extremity chronic pain treated at a hospital-based interdisciplinary rehabilitation center. DESIGN: This was a cross-sectional study with retrospective review of 173 individuals, 8 to 18 years old, treated from June 2008 to 2013. METHODS: The measures used were the Timed Up and Go, Timed Up and Down Stairs, Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, 6-minute walk test, and Lower Extremity Functional Scale. Participant performance was correlated with demographic characteristics, the Functional Disability Index, Multidimensional Anxiety Scale for Children, Child Depression Inventory, and Canadian Occupational Performance Measure. RESULTS: Scores from all 5 PT measures showed significant improvement following treatment. Functional Disability Index correlated to every PT measure except the 6-minute walk test. CONCLUSIONS: This study supports the clinical use of these PT measures to track functional progress after rehabilitative treatment of lower extremity chronic pain-related disability.

Quality Assessment of Meta-analyses Published in Leading Anesthesiology Journals From 2005 to 2014.

Meta-analysis, when preceded by a systematic review, is considered the "gold standard" in data aggregation; however, the quality of meta-analyses is often questionable, leading to uncertainty about the accuracy of results. In this study, we evaluate the quality of meta-analyses published in 5 leading anesthesiology journals from 2005 to 2014. A total of 220 meta-analyses published in Anesthesiology, Pain, British Journal of Anaesthesia, Anaesthesia, or Anesthesia & Analgesia were identified for inclusion. The quality of each meta-analysis was determined using the Revised Assessment of Multiple Systematic Reviews (R-AMSTAR). R-AMSTAR rated 11 questions related to systematic reviews and meta-analyses on a scale of 1-4, with 4 representing the highest quality. Overall meta-analyses quality was evaluated using a Spearmen regression analysis and found to positively correlate with time (rs = 0.24, P < .001). Similarly, a temporal association was found for conflict of interest (rs = 0.51, P < .001) and comprised a list of included and excluded studies (rs = 0.32, P < .001). In conclusion, the quality of meta-analyses published in leading anesthesiology journals has increased over the last decade. Furthermore, assessing the scientific quality of included studies in meta-analyses (P = .60) and using this assessment to formulate conclusions and/or recommendations (P = .67) remains relatively low (median R-AMSTAR: 2, interquartile range [IQR]: 2-3]; median R-AMSTAR: 2, IQR: 1-2, respectively).

Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Pediatric Critically Ill Patient: Society of Critical Care Medicine and American Society for Parenteral and Enteral Nutrition.

This document represents the first collaboration between two organizations, American Society of Parenteral and Enteral Nutrition and the Society of Critical Care Medicine, to describe best practices in nutrition therapy in critically ill children. The target of these guidelines is intended to be the pediatric (> 1 mo and < 18 yr) critically ill patient expected to require a length of stay greater than 2 or 3 days in a PICU admitting medical, surgical, and cardiac patients. In total, 2,032 citations were scanned for relevance. The PubMed/Medline search resulted in 960 citations for clinical trials and 925 citations for cohort studies. The EMBASE search for clinical trials culled 1,661 citations. In total, the search for clinical trials yielded 1,107 citations, whereas the cohort search yielded 925. After careful review, 16 randomized controlled trials and 37 cohort studies appeared to answer one of the eight preidentified question groups for this guideline. We used the Grading of Recommendations, Assessment, Development and Evaluation criteria to adjust the evidence grade based on assessment of the quality of study design and execution. These guidelines are not intended for neonates or adult patients. The guidelines reiterate the importance of nutritional assessment, particularly the detection of malnourished patients who are most vulnerable and therefore potentially may benefit from timely intervention. There is a need for renewed focus on accurate estimation of energy needs and attention to optimizing protein intake. Indirect calorimetry, where feasible, and cautious use of estimating equations and increased surveillance for unintended caloric underfeeding and overfeeding are recommended. Optimal protein intake and its correlation with clinical outcomes are areas of great interest. The optimal route and timing of nutrient delivery is an area of intense debate and investigations. Enteral nutrition remains the preferred route for nutrient delivery. Several strategies to optimize enteral nutrition during critical illness have emerged. The role of supplemental parenteral nutrition has been highlighted, and a delayed approach appears to be beneficial. Immunonutrition cannot be currently recommended. Overall, the pediatric critical care population is heterogeneous, and a nuanced approach to individualizing nutrition support with the aim of improving clinical outcomes is necessary.

Effects of Physical Exercise Interventions on Gait-Related Dual-Task Interference in Older Adults: A Systematic Review and Meta-Analysis.

Dual-task interference during walking can substantially limit mobility and increase the risk of falls among community-dwelling older adults. Previous systematic reviews examining intervention effects on dual-task gait and mobility have not assessed relative dual-task costs (DTC) or investigated whether there are differences in treatment-related changes based on the type of dual task or the type of control group. The purpose of this systematic review was to examine the effects of physical exercise interventions on dual-task performance during walking in older adults. A meta-analysis of randomized controlled trials (RCTs) compared treatment effects between physical exercise intervention and control groups on single- and dual-task gait speed and relative DTC on gait speed. A systematic search of the literature was conducted using the electronic databases PubMed, CINAHL, EMBASE, Web of Science, and PsycINFO searched up to September 19, 2014. Randomized, nonrandomized, and uncontrolled studies published in English and involving older adults were selected. Studies had to include a physical exercise intervention protocol and measure gait parameters during continuous, unobstructed walking in single- and dual-task conditions before and after the intervention. Of 614 abstracts, 21 studies met the inclusion criteria and were included in the systematic review. Fourteen RCTs were included in the meta-analysis. The mean difference between the intervention and control groups significantly favored the intervention for single-task gait speed (mean difference: 0.06 m/s, 95% CI: 0.03, 0.10, p < 0.001), dual-task gait speed (mean difference: 0.11 m/s, 95% CI 0.07, 0.15, p < 0.001), and DTC on gait speed (mean difference: 5.23%, 95% CI 1.40, 9.05, p = 0.007). Evidence from subgroup comparisons showed no difference in treatment-related changes between cognitive-motor and motor-motor dual tasks, or when interventions were compared to active or inactive controls. In summary, physical exercise interventions can improve dual-task walking in older adults primarily by increasing the speed at which individuals walk in dual-task conditions. Currently, evidence concerning whether physical exercise interventions reduce DTC or alter the self-selected dual-task strategy during unobstructed walking is greatly lacking, mainly due to the failure of studies to measure and report reciprocal dual-task effects on the non-gait task.

The analgesic effect of a vapocoolant stream spray in reducing heat nociception on the glabrous skin of rat pups.

BACKGROUND: Blood sampling is a common screening and diagnostic test in newborn infants in the neonatal intensive care unit, and heel lancing accounts for two-thirds of these tests. Heel lancing causes acute pain and distress, and most infants rarely receive analgesics because of fear of respiratory depression from opioids and lack of effectiveness of topical local anesthetics on the glabrous skin. To circumvent this latter problem, we investigated the analgesic efficacy and safety of a topical vapocoolant spray. METHODS: Forty Sprague-Dawley rat pups aged 7 days old were randomly assigned to receive either vapocoolant or saline spray on the plantar hindpaws for 5 to 6 seconds. Forty-five seconds later, the paws were subjected to a modified hotplate test to quantify the nociceptive flexor withdrawal (NFW) thresholds before and after treatment with the sprays. Seven days later, the animals were euthanized and the hindpaws were examined histologically. A nested analysis of variance approach was used to account for the triplicate measurements per animal. A 2-tailed P < 0.05 was considered significant. RESULTS: At baseline, there were no differences in the NFW thresholds between the 2 groups (P = 0.22). After treatment, these thresholds were significantly lower in both vapocoolant (P < 0.001) and saline (P = 0.008) groups relative to baseline values. The vapocoolant group demonstrated a significantly longer NFW latency time compared to the saline group (P < 0.001). All specimens in both groups were examined and showed normal skin histology. CONCLUSIONS: Vapocoolant spray treatment of the glabrous skin is effective and safe after a single treatment.

Non-targeted analysis (NTA) and suspect screening analysis (SSA): a review of examining the chemical exposome.

Non-targeted analysis (NTA) and suspect screening analysis (SSA) are powerful techniques that rely on high-resolution mass spectrometry (HRMS) and computational tools to detect and identify unknown or suspected chemicals in the exposome. Fully understanding the chemical exposome requires characterization of both environmental media and human specimens. As such, we conducted a review to examine the use of different NTA and SSA methods in various exposure media and human samples, including the results and chemicals detected. The literature review was conducted by searching literature databases, such as PubMed and Web of Science, for keywords, such as "non-targeted analysis", "suspect screening analysis" and the exposure media. Sources of human exposure to environmental chemicals discussed in this review include water, air, soil/sediment, dust, and food and consumer products. The use of NTA for exposure discovery in human biospecimen is also reviewed. The chemical space that has been captured using NTA varies by media analyzed and analytical platform. In each media the chemicals that were frequently detected using NTA were: per- and polyfluoroalkyl substances (PFAS) and pharmaceuticals in water, pesticides and polyaromatic hydrocarbons (PAHs) in soil and sediment, volatile and semi-volatile organic compounds in air, flame retardants in dust, plasticizers in consumer products, and plasticizers, pesticides, and halogenated compounds in human samples. Some studies reviewed herein used both liquid chromatography (LC) and gas chromatography (GC) HRMS to increase the detected chemical space (16%); however, the majority (51%) only used LC-HRMS and fewer used GC-HRMS (32%). Finally, we identify knowledge and technology gaps that must be overcome to fully assess potential chemical exposures using NTA. Understanding the chemical space is essential to identifying and prioritizing gaps in our understanding of exposure sources and prior exposures. IMPACT STATEMENT: This review examines the results and chemicals detected by analyzing exposure media and human samples using high-resolution mass spectrometry based non-targeted analysis (NTA) and suspect screening analysis (SSA).

Gestational organophosphate ester exposure and preschool attention-deficit/hyperactivity disorder in the Norwegian Mother, Father, and Child cohort study.

BACKGROUND: Attention-deficit/hyperactivity-disorder (ADHD) is a leading neurodevelopmental disorder in children worldwide; however, few modifiable risk factors have been identified. Organophosphate esters (OPEs) are ubiquitous chemical compounds that are increasingly prevalent as a replacement for other regulated chemicals. Current research has linked OPEs to neurodevelopmental deficits. The purpose of this study was to assess gestational OPE exposure on clinically-assessed ADHD in children at age 3 years. METHODS: In this nested case-control study within the Norwegian Mother, Father, and Child Cohort study, we evaluated the impact of OPE exposure at 17 weeks' gestation on preschool-age ADHD. Between 2007 and 2011, 260 ADHD cases were identified using the Preschool Age Psychiatric Assessment and compared to a birth-year-stratified control group of 549 children. We categorized bis(2-butoxyethyl) phosphate (BBOEP) and bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) as values < limit of detection (LOD) (BBOEP N = 386, BDCIPP N = 632), ≥LOD but < limit of quantification (LOQ) (BBOEP N = 413; BDCIPP N = 75), or above LOQ (BBOEP N = 70; BDCIPP N = 102). Diphenyl phosphate (DPhP) and di-n-butyl phosphate (DnBP) were categorized as quartiles and also modeled with a log10 linear term. We estimated multivariable adjusted odds ratios (ORs) using logistic regression and examined modification by sex using an augmented product term approach. RESULTS: Mothers in the 3rd DnBP quartile had 1.71 times the odds of having a child with ADHD compared to the 1st quartile (95%CI: 1.13, 2.58); a similar trend was observed for log10 DnBP and ADHD. Mothers with BDCIPP ≥ LOD but < LOQ had 1.39 times the odds of having a child with ADHD compared to those with BDCIPP < LOD (95%CI: 0.83, 2.31). Girls had lower odds of ADHD with increasing BBOEP exposure (log10 OR: 0.55 (95%CI: 0.37, 0.93), however boys had a weakly increased odds (log10 OR: 1.25 (95%CI: 0.74, 2.11) p-interaction = 0.01]. CONCLUSIONS: We found modest increased odds of preschool ADHD with higher DnBP and BDCIPP exposure.

Prenatal organophosphate ester exposure and executive function in Norwegian preschoolers.

Organophosphate esters (OPEs) are ubiquitous chemicals, used as flame retardants and plasticizers. OPE usage has increased over time as a substitute for other controlled compounds. This study investigates the impact of prenatal OPE exposure on executive function (EF) in preschoolers. Methods: We selected 340 preschoolers from the Norwegian Mother, Father, and Child Cohort Study. Diphenyl-phosphate (DPhP), di-n-butyl-phosphate (DnBP), bis(2-butoxyethyl) phosphate (BBOEP), and bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) were measured in maternal urine. EF was measured using the Behavior Rating Inventory of Executive Functioning-Preschool (BRIEF-P) and the Stanford-Binet fifth edition (SB-5). EF scores were scaled so a higher score indicated worse performance. We estimated exposure-outcome associations and evaluated modification by child sex using linear regression. Results: Higher DnBP was associated with lower EF scores across multiple rater-based domains. Higher DPhP and BDCIPP were associated with lower SB-5 verbal working memory (ß = 0.49, 95% CI = 0.12, 0.87; ß = 0.53, 95% CI = 0.08, 1.02), and higher BBOEP was associated with lower teacher-rated inhibition (ß = 0.34, 95% CI = 0.01, 0.63). DPhP was associated with lower parent-reported BRIEF-P measures in boys but not girls [inhibition: boys: 0.37 (95% CI = 0.03, 0.93); girls: -0.48 (95% CI = -1.27, 0.19); emotional control: boys: 0.44 (95% CI = -0.13, 1.26); girls: -0.83 (95% CI = -1.73, -0.00); working memory: boys: 0.49 (95% CI = 0.03, 1.08); girls: -0.40 (95% CI = -1.11, 0.36)]. Fewer sex interactions were observed for DnBP, BBOEP, and BDCIPP, with irregular patterns observed across EF domains. Conclusions: We found some evidence prenatal OPE exposure may impact EF in preschoolers and variation in associations by sex.

Organophosphorus Pesticide Exposure at 17 Weeks' Gestation and Odds of Offspring Attention-Deficit/Hyperactivity Disorder Diagnosis in the Norwegian Mother, Father, and Child Cohort Study.

Prenatal organophosphorus pesticides (OPs) are ubiquitous and have been linked to adverse neurodevelopmental outcomes. However, few studies have examined prenatal OPs in relation to diagnosed attention-deficit/hyperactivity disorder (ADHD), with only two studies exploring this relationship in a population primarily exposed through diet. In this study, we used a nested case-control study to evaluate prenatal OP exposure and ADHD diagnosis in the Norwegian Mother, Father, and Child Cohort Study (MoBa). For births that occurred between 2003 and 2008, ADHD diagnoses were obtained from linkage of MoBa participants with the Norwegian Patient Registry (N = 297), and a reference population was randomly selected from the eligible population (N = 552). Maternal urine samples were collected at 17 weeks' gestation and molar sums of diethyl phosphates (ΣDEP) and dimethyl phosphates metabolites (ΣDMP) were calculated. Multivariable adjusted logistic regression models were used to estimate the association between prenatal OP metabolite exposure and child ADHD diagnosis. Additionally, multiplicative effect measure modification (EMM) by child sex was assessed. In most cases, mothers in the second and third tertiles of ΣDMP and ΣDEP exposure had slightly lower odds of having a child with ADHD, although confidence intervals were wide and included the null. EMM by child sex was not observed for either ΣDMP or ΣDEP. In summary, we did not find evidence that OPs at 17 weeks' gestation increased the odds of ADHD in this nested case-control study of ADHD in MoBa, a population primarily experiencing dietary exposure.

Prenatal Exposure to Organophosphorus Pesticides and Preschool ADHD in the Norwegian Mother, Father and Child Cohort Study.

Prenatal organophosphorus pesticide (OPP) exposure has been associated with child attention-deficit/hyperactivity disorder (ADHD) in agricultural communities and those that are exposed to residentially applied insecticides. To examine this association in populations that are exposed primarily through diet, we estimate the associations between prenatal OPP exposure and preschool ADHD in the Norwegian Mother, Father and Child Cohort Study (MoBa), and describe modification by paraoxonase 1 (PON1) gene variants. We used participants from the MoBa Preschool ADHD Sub-study (n = 259 cases) and a random sample of MoBa sub-cohort participants (n = 547) with birth years from 2004 to 2008. Prenatal urinary dialkylphosphate (DAP) metabolites (total diethylphosphate [∑DEP] and total dimethylphosphate [∑DMP]) were measured by an ultra-performance liquid chromatography-time-of-flight system and summed by molar concentration. Maternal DNA was genotyped for coding variants of PON1 (Q192R and L55M). We used a multivariable logistic regression to calculate the odds ratios (OR) and 95% confidence intervals, adjusted for maternal education, parity, income dependency, age, marital status, ADHD-like symptoms, pesticide use, produce consumption, and season. We found no associations between DAP metabolite concentrations and preschool ADHD. The adjusted ORs for exposure quartiles 2-4 relative to 1 were slightly inverse. No monotonic trends were observed, and the estimates lacked precision, likely due to the small sample size and variation in the population. We found no evidence of modification by PON1 SNP variation or child sex. Maternal urinary DAP concentrations were not associated with preschool ADHD.

American Society for Parenteral and Enteral Nutrition Clinical Guidelines: The Validity of Body Composition Assessment in Clinical Populations.

On behalf of the American Society for Parenteral and Enteral Nutrition (ASPEN), a systematic review was conducted to evaluate the best available evidence regarding the validity of relevant body composition methods (eg, dual energy X-ray absorptiometry [DXA], ultrasound [US], and bioelectrical impedance analysis [BIA]) in clinical populations. The guidelines targeted adults >18 years of age with a potentially inflammatory condition or pathological end point associated with a specific disease or clinical condition. In total, 7375 studies were retrieved, and 15 DXA, 7 US, and 23 BIA studies provided applicable data. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used to assess the diagnostic accuracy of the test method against a "gold standard" reference. The Grading of Recommendations, Assessment, Development and Evaluation criteria were used to separate the evaluation of the body of evidence from the recommendations. Based on a limited number of studies and expert opinion, DXA is recommended for the assessment of fat mass in patients with a variety of disease states; however, the validity of DXA for lean mass assessment in any clinical population remains unknown. No recommendations can be made at this time to support the use of US or BIA in the clinical setting, as data to support its validity in any specific patient population are limited in scope or by the proprietary nature of manufacture-specific BIA regression models to procure body composition data, respectively. Directions for future research are provided. These clinical guidelines were approved by the ASPEN Board of Directors.

[ASPEN-FELANPE Clinical Guidelines: Nutrition Support of Adult Patients with Enterocutaneous Fistula]. / Guías Clínicas ASPEN-FELANPE: Terapia Nutricional en Pacientes Adultos con Fístulas Enterocutáneas.

INTRODUCTION: Background: the management of patients with enterocutaneous fistula (ECF) requires an interdisciplinary approach and poses a significant challenge to surgeons, gastroenterologists, intensivists, wound/stoma care specialists, and nutrition support clinicians. Available guidelines for optimizing nutritional status in these patients are often vague, based on limited and dated clinical studies, and typically rely on individual or institutional experience. Specific nutrient requirements, appropriate route of feeding, role of immune-enhancing nutrients, and use of somatostatin analogs in the management of patients with ECF remain a challenge for the clinician. The purpose of this clinical guideline is to develop recommendations for the nutritional care of adult patients with ECF. Methods: a systematic review of the best available evidence to answer a series of questions regarding clinical management of adults with ECF was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group. An anonymous consensus process was used to develop the clinical guideline recommendations prior to peer review and approval by the A.S.P.E.N. and FELANPE Board of Directors. Questions: in adult patients with enterocutaneous fistula: 1) What factors best describe nutritional status? 2) What is the preferred route of nutritional therapy (oral diet, EN or PN)? 3) What protein and energy intake provide best clinical outcomes? 4) Is fistuloclysis associated with better outcomes than standard care? 5) Are immune-enhancing nutrients associated with better outcomes? 6) Does the use of somatostatin provide better outcomes than standard medical therapy? 7) When is home parenteral nutrition support indicated?

INTRODUCCIÓN: Introducción: el manejo de las fístulas enterocutáneas (FEC) es un reto que requiere enfoque interdisciplinario y plantea un desafío importante. Las guías para optimizar el estado nutricional en estos pacientes están basadas en estudios que dependen de la experiencia individual y, ocasionalmente, institucional; que se focalizan en el tratamiento integral de las FEC, centrándose en el manejo médico y quirúrgico, mientras que la terapia nutricional se revisa solo superficialmente. Los requerimientos nutricionales, vía de administración, uso de inmunonutrición y de análogos de la somatostatina en el tratamiento de estos pacientes no están bien definidos. El objetivo de esta guía es desarrollar recomendaciones específicas para la terapia nutricional de los pacientes adultos con FEC. Método: revisión sistemática de la mejor evidencia disponible para responder a una serie de preguntas sobre la terapia nutricional de los adultos con FEC, evaluada utilizando la metodología GRADE. Se utilizó un proceso de consenso anónimo para desarrollar las recomendaciones de la guía clínica antes de la revisión por pares y la aprobación por las Juntas Directivas de ASPEN y FELANPE. Preguntas: 1) ¿Qué factores describen mejor el estado nutricional de los adultos con FEC? 2) ¿Cuál es la mejor vía para administrar la terapia nutricional (oral, nutrición enteral o parenteral)? 3) ¿Qué aporte energético y proteico proporciona mejores resultados clínicos? 4) ¿El uso de la fistuloclisis se asocia a mejores resultados? 5) ¿Las fórmulas inmunomoduladoras se asocian a mejores resultados? 6) ¿El uso de la somatostatina proporciona mejores resultados? 7) ¿Cuándo está indicada la terapia nutricional parenteral domiciliaria?

American Society for Parenteral and Enteral Nutrition Guidelines for the Selection and Care of Central Venous Access Devices for Adult Home Parenteral Nutrition Administration.

This document represents the American Society for Parenteral and Enteral Nutrition (ASPEN) clinical guidelines to describe best practices in the selection and care of central venous access devices (CVADs) for the infusion of home parenteral nutrition (HPN) admixtures in adult patients. The guidelines targeted adults >18 years of age in which the intervention or exposure had to include HPN that was administered via a CVAD. Case studies, non-English studies, or studies of CVAD no longer available in the United States were excluded. In total, 564 abstract citations, 350 from Medline and 214 from PubMed/non-MEDLINE databases, were scanned for relevance. Of the 564 citations, 13 studies addressed at least 1 of the 6 guideline-related questions, and none of the studies were prospective and randomized. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria were used to adjust the evidence grade based on assessment of the quality of study design and execution. Recommendations for the CVAD type, composition, or number of lumens to minimize infectious or mechanical complications are based on a limited number of studies and expert opinion of the authors, all very experienced in home infusion therapy. No studies were found that compared best solutions for routine flushing of lumens (eg, heparin versus saline) or for maintaining catheters in situ while treating CVAD mechanical or infectious complications. It is clear that studies to answer these questions are very limited, and further research is needed. These clinical guidelines were approved by the ASPEN Board of Directors.

Comparison of Anterior and Posterior Cortico-steroid Injections for Pain Relief and Functional Improvement in Shoulder Impingement Syndrome.

Subacromial impingement syndrome (SIS) is the most common cause of shoulder pain. Treatment options for SIS include conservative modalities such as use of nonsteroidal anti-inflammatory drugs, physical therapy, and subacromial corticosteroid injections (CSIs). Although studies have found improvement in pain, function, and range of motion after CSI, the effect of injection route (anterior or posterior) on shoulder pain in patients with SIS has not been investigated. In the study reported here, patients were randomly assigned to 2 treatment groups: anterior CSI and posterior CSI. Pain was assessed with a visual analog scale (VAS) and function with the Single Assessment Numeric Evaluation (SANE). Patients were evaluated before injection (baseline) and 1, 3, and 6 months after injection. Of the 55 patients enrolled, 25 received anterior CSI and 30 received posterior CSI. The 2 groups showed no significant difference in VAS pain at baseline or 1, 3, or 6 months after injection. SANE scores were statistically different at 3 months. Each group had significantly less pain and better function 1, 3, and 6 months after injection than at baseline. Age, sex, and body mass index did not significantly affect the efficacy of anterior or posterior CSIs. In patients with SIS, subacromial CSI reduces pain and improves function for up to 6 months. These effects are no different for anterior and posterior injection routes. As a result, clinicians should rely on their clinical acumen when selecting injection routes, as anterior and posterior are both beneficial.

Longitudinal Photogrammetric Analysis of the Columellar-Labial Angle following Primary Repair of Bilateral Cleft Lip and Nasal Deformity.

BACKGROUND: The changing nasolabial dimensions after repair of bilateral cleft lip and nasal deformity can be documented by anthropometry; however, the columellar-labial angle is rarely measured. METHODS: This is a study of white patients who had synchronous repair of bilateral cleft lip performed by one surgeon (J.B.M.). The columellar-labial angle was measured on lateral photographs with the subject in neutral head position. Average values for columellar-labial angle at two or more time points were analyzed with a general estimating equation and cubic modeling. Values for complete and incomplete bilateral cleft lips were compared to each other and to Farkas' norms. Direct anthropometric measurements of intraoperative columellar length were compared to the postoperative columellar-labial angle using Pearson correlation analysis. RESULTS: Eighty-five patients were studied (64 complete and 21 incomplete clefts). The average photographic follow-up interval was 10 years (range, 1.8 to 19.5 years). The columellar-labial angle in bilateral complete clefts was significantly greater than in incomplete forms (p = 0.002). Although the angles decreased with time, they remained significantly greater than Farkas' normative values in both cleft groups (all p < 0.05). There was no correlation between the magnitude of columellar lengthening achieved during primary nasal correction and the postoperative columellar-labial angle. CONCLUSIONS: An obtuse columellar-labial angle can occur following synchronous nasolabial repair of a bilateral cleft lip, particularly in patients with a complete deformity. Although the angle narrows in time, it remains 1 to 2 SD greater than normal values. Secondary nasal correction may be needed if there is excessive tip rotation after completion of growth and orthognathic surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Revisiting Tension Band Fixation for Difficult Patellar Fractures.

Patella fractures with comminution, osteoporotic bone, and/or previously failed fixation are exceedingly difficult to reduce and fix. Moreover, the risk of symptomatic constructs and patients who are poorly compliant with postoperative activity restrictions can make these complex fracture patterns an even more challenging scenario. Although there is an array of techniques described for comminuted patella fractures, there lacks an accepted surgical technique for these difficult cases. In this clinical series, we describe an enhancement to the traditional tension band construct that uses additional wires and multiple tension bands to gather and fix comminuted fracture patterns in nontransverse planes, bolster osteoporotic bone, and secure fractures in patients undergoing a revision and/or have potential to be poorly compliant with postoperative activity restrictions. The clinical outcomes of 27 patients demonstrate high rates of bony union, functional range of motion, and low rates of both infection and failure. In conclusion, using the basic principles of tension band wiring remains highly versatile, useful, and economical in approaching difficult patella fractures.
