RESUMO

Little is known about whether body composition changes differently between children with and without obesity following 1 year of nonintervention. Therefore, we investigated body composition in early pubescent children (8-12 yr) with and without obesity before and after a period of 1 year of nonintervention. Early pubescent children (8-12 yr; Tanner stage ≤ 3) with (body mass index, BMI ≥ 95th percentile) and without obesity (15th < BMI < 85th percentile) were recruited. At baseline, 88 children (n = 25 without obesity) completed dual-energy X-ray absorptiometry imaging (DXA) for body composition measurements [%body fat, fat mass, fat-free mass (FFM)]. One year later, 47 participants (n = 15 without obesity) returned for repeat testing. The children without obesity were older (11.0 ± 1.0 vs. 10.0 ± 1.2 yr; means ± SD) (P = 0.013). There was no group difference in height, and both groups increased in height similarly after 1 year (147.7 ± 8.9 to 154.5 ± 9.2 cm without vs. 145.6 ± 5.8 to 152.5 ± 5.9 cm with obesity) (P < 0.001). Weight was greater (P < 0.001) in children with obesity at baseline as was the increase in weight after 1 yr (9.25 vs. 5.82 kg) (interaction, P = 0.005). Fat mass increased by 4.4 kg in children with obesity and by 1.1 kg in children without obesity (interaction, P < 0.001). However, there was no difference in fat-free mass between those with and without obesity at baseline (29.9 ± 5.9 vs. 31.6 ± 4.8 kg) (P = 0.206) with both groups increasing similarly over 1 year (gain of 4.87 vs. 4.85 kg with and without obesity, respectively). Without intervention, the increase in fat mass is four times greater in children with obesity after 1 year as compared with children without obesity.NEW & NOTEWORTHY Little is known about changes in body composition in children with and without obesity following 1 year of nonintervention. We report that without intervention, fat mass gain is significantly greater in children with obesity after 1 year compared with those without obesity. Body mass index (BMI) and %body fat measurements after 1 year yielded no significant increase suggesting that BMI and %fat alone are not suitable measures for tracking changes in adiposity among children.

RESUMO

BACKGROUND: The rising incidence and complexity of revision knee arthroplasty has led to an increase in the use of metaphyseal reconstruction systems. One of the most widely used systems are metaphyseal sleeves as they have demonstrated excellent long-term survival. However, there is concern about the possible difficulty of extracting a sleeve if it were necessary, as no known procedures have yet been validated. METHODS: We examined the outcomes of removing 23 well-integrated metaphyseal sleeves using the same systematized technique. RESULTS: All sleeves were extracted without any intraoperative complications. Four subjects required an osteotomy to complete the extraction, while 62% of the sample were found to have an AORI IIB defect. All cases were successfully reconstructed with a new metaphyseal fixation, implanting a new sleeve in 38% of subjects compared with cones in the remaining 62%. CONCLUSIONS: The technique described here produced successful, reproducible outcomes for the removal of integrated metaphyseal sleeves with minimal bone loss and no intraoperative complications.

RESUMO

BACKGROUND: The association of asthma and metabolic syndrome (MetS) among adolescents and young adults (AYAs) remains unclear, as well as the role of obesity in this relationship. METHODS: AYAs aged 12-25 years who participated in the 2011-2020 National Health and Nutrition Examination Survey were included in this cross-sectional analysis. The moderating effect of obesity (age- and sex-adjusted body mass index ≥ 95th%ile for adolescents or ≥ 30 kg/m2 for adults) on asthma and MetS were evaluated in four groups: 1) both asthma and obesity; 2) asthma and no obesity; 3) obesity and no asthma; and 4) healthy controls with no obesity/asthma. RESULTS: A total of 7,709 AYAs (53.9% aged 12-18 years, 51.1% males, and 54.4% non-Hispanic White) were included in this analysis. 3.6% (95% CI 2.8-4.3%) had obesity and asthma, 7.6% (95% CI 6.8-8.4%) had asthma and no obesity, 21.4% (95% CI 19.6-23.2%) had obesity and no asthma, and 67.4% (95% CI 65.4-69.4%) had neither obesity nor asthma. The estimated prevalence of MetS was greater among those with both obesity and asthma versus those with only asthma (4.5% [95% CI 1.7-7.3%] vs. 0.2% [95% CI 0-0.5%], p < 0.001). Compared to healthy controls, those with both obesity and asthma had ∼10 times higher odds of having MetS (aOR 10.5, 95% CI 3.9-28.1). CONCLUSIONS: Our results show the association between MetS and asthma is stronger in AYAs with BMI-defined obesity. Efforts to prevent and treat obesity may reduce MetS occurrence in AYAs with asthma.

RESUMO

Despite growing recognition of the need for increased diversity among students, trainees, and faculty in health care, the medical workforce still lacks adequate representation from groups historically underrepresented in medicine (URiM). The subspecialty field of pediatric pulmonology is no exception. Although there have been efforts to address issues of diversity, equity, and inclusion (DEI) in our own field, gaps persist. To address these gaps, the members of the Diversity, Equity, and Inclusion Advisory Group (DEI-AG) of the American Thoracic Society Pediatrics Assembly created and distributed a Needs Assessment Survey in the United States and Canada to better understand the racial and ethnic demographics of the pediatric pulmonary workforce and to learn more about successes, gaps, and opportunities to enhance how we recruit, train, and retain a diverse workforce. The DEI-AG leadership cochairs convened a workshop to review the findings of the DEI Needs Assessment Survey and to develop strategies to improve the recruitment and retention of URiM fellows and faculty. This Official ATS Workshop Report aims to identify barriers and opportunities for recruitment, training, and career development within the field of pediatric pulmonology. Additionally, we offer useful strategies and resources to improve the recruitment of URiM residents, the mentorship of trainees and junior faculty, and the career development of URiM faculty in academic centers. This Workshop Report is an important first deliverable by the DEI-AG. We hope that this work, originating from within the Pediatrics Assembly, will serve as a model for other Assemblies, disciplines across the ATS, and other fields in Pediatrics.

RESUMO

BACKGROUND: We hypothesized that, as posterior malleolar ankle fractures usually present one or two main fragments, the buttress plating principle can be successfully achieved either with conventional nonlocking or anatomic locking posterior tibia plates, and no clinical differences should be found. The aim of this study was to evaluate the outcomes of posterior malleolar ankle (PM) fractures treated with conventional nonlocking (CNP) or anatomic locking plates (ALP), and also to compare both constructs in terms of crude costs. METHODS: A retrospective cohort study was designed. CNP was used in 22 patients and ALP was used in 11 patients. American Orthopedic Foot and Ankle Society (AOFAS) score was registered at four weeks, 3-6 months, 12 and 24 months to assess all patients' functional status. The primary outcome was ankle and hindfoot AOFAS score at 12 months follow-up visit. All complications, radiographic evaluation and implant construct costs were also registered and compared. The average follow-up was 25.4 (range, 12-42) months. RESULTS: No significant difference was observed between both cohorts, in terms of AOFAS score and complication rate (P > .05). We found that ALP construct is 17 times more expensive than CNP construct in our institution (P < .001). CONCLUSION: Anatomic locking posterior tibial plates may be an interesting device when poor bone quality is present or when a true multifragmentary pilon fracture is faced. Anatomic locking posterior tibia plate should not become a regular implant for any PM fracture since equivalent clinical and radiological results were obtained in our study using CNP with a significant reduced cost.

RESUMO

INTRODUCTION: Adolescent patients make up a significant number of the primary care population, yet medical training specific to adolescents is inadequate and challenging. 2 Medical trainees report feeling less competent caring for adolescents compared to caring for infants and children. 3 Framed after an adolescent HEADSS (Home, Education/employment, peer group Activities, Drugs, Sexuality and Suicide/depression) interview role-play activity for pediatric clerkship students, 1,2 this study sought to investigate the impact that facilitated role-play would have on physician assistant (PA) students' self-perceived knowledge, skills, and comfort in interviewing adolescents. METHODS: A coached role-play focused on skills used during a HEADSS interview was used to demonstrate the communication skills inherently important to adolescent encounters. Pre- and postintervention surveys were administered. RESULTS: Data from 2 sequential cohorts (n = 88) showed statistically significant improvement in pre- versus postsession self-perception of knowledge ( p ≤ 0.0001) and skills ( p ≤ 0.0001), but not in comfort ( p = 0.1610). DISCUSSION: Teaching PA students how best to engage with adolescents can be done effectively via coached role-play.

RESUMO

BACKGROUND: In children, obesity typically reduces functional residual capacity (FRC), which reduces airway caliber and increases airway resistance. Whether these obesity-related changes in respiratory function can alter bronchodilator responsiveness is unknown. OBJECTIVE: To investigate bronchodilator responsiveness in nonasthmatic children with and without obesity. METHODS: Seventy nonasthmatic children, 8-12 years old, without (n = 19) and with (n = 51) obesity, completed spirometry, impulse oscillometry, and airway resistance measurements through plethysmography pre/post 360 µg of inhaled albuterol. FRC was assessed pre albuterol. A two-way analysis of variance determined the effects of obesity (group) and inhaled albuterol (pre-post) on outcome measures. RESULTS: FRC (%total lung capacity) was 16% lower in children with obesity compared with those without obesity. There was no significant group by pre-post albuterol interaction on any outcome variables. Albuterol inhalation reduced total, central and peripheral airway resistance and increased airway reactance (i.e., less negative) to a similar degree in children with and without obesity. In children with obesity, airway resistance was increased whether measured by impulse oscillometry or plethysmography. However, once airway resistance was adjusted for lung volumes (i.e., specific airway resistance or sRaw ), there were no differences between children with and without obesity. In addition, significant but moderate associations were detected between chest mass and FRC (r = -0.566; p < 0.001), FRC and total airway resistance (i.e., Raw ; r = -0.445; p < 0.001). CONCLUSIONS: In nonasthmatic early pubescent children, obesity increases total, central, and peripheral respiratory system resistance. However, the added respiratory system resistance and low lung volume breathing with obesity are not sufficient to reduce bronchodilator responsiveness.

RESUMO

Forced mid-expiratory flow (i.e., isoFEF25-75) may increase with a short-acting ß2-agonist in nonasthmatic children without bronchodilator responsiveness. This could also increase estimated ventilatory capacity along mid-expiration (V̇Ecap25-75), especially in vulnerable children with obesity who exhibit altered breathing mechanics. We estimated V̇Ecap25-75 pre- and post-albuterol treatment in 8-12yo children without (n = 28) and with (n = 46) obesity. A two-way ANOVA was performed to determine effects of an inhaled bronchodilator (pre-post) and obesity (group) on isoFEF25-75 and V̇Ecap25-75. There was no group by bronchodilator interaction or main group effect on outcome variables. However, a significant main effect of the bronchodilator was detected in spirometry parameters, including a substantial increase in isoFEF25-75 (17.1 ±â€¯18.0 %) and only a slight (non-clinical) but significant increase in FEV1 (2.4 ±â€¯4.3 %). V̇Ecap25-75 significantly increased with albuterol (+11.7 ±â€¯10.6 L/min; +15.8 ±â€¯13.9 %). These findings imply potentially important increases in ventilatory reserve with a bronchodilator in nonasthmatic children without and with obesity, which could potentially influence respiratory function at rest and during exercise.

RESUMO

INTRODUCTION: The previously reported Patients' Experience of LIving with CANcer-associated thrombosis (PELICAN) identified several areas of unmet clinical and support need for cancer patients diagnosed with venous thromboembolism (VTE) in the UK. It is not known whether such experiences are restricted to one particular country's healthcare system and culture. We therefore undertook an evaluation of patients' experience of cancer-associated thrombosis (CAT) within a Spanish setting. METHODS: Twenty consecutive Spanish patients with CAT were interviewed about their experiences of living with CAT as per the previous PELICAN study. Where possible, spouses were interviewed in conjunction. Semi-structured interviews were audio recorded, transcribed and translated into English. Transcripts were coded using Nvivo software and data were analysed using framework analysis. A pragmatic approach was undertaken to allow explication of the potential cultural and operational differences that were not apparent in the UK dataset. RESULTS: Several commonalities between the UK and Spanish patients were identified including the traumatic nature of the experience, the need for information and adaptive behaviors through ritualisation. Within the major themes lay new themes as follows. (1) The traumatic experience of CAT impacted on the family dynamic with respect to discussions within the family unit and support needs of individuals other than the patient. It also had a profound impact on the patient's concept of self with increased awareness of their mortality and seriousness of the cancer. (2) The need for information extended to the family as well as the patients. This was needed at the point of CAT diagnosis as well as an opportunity to later address unanswered questions. (3) Adaptive behaviors were common with similar ritualisations seen in the UK patients. CONCLUSION: The distress experienced by patients with CAT is not isolated to the UK alone but is similar in Spanish patients as well. The patient information provided regarding LMWH injections is important, but there is a need to for patients and their families to be given additional information about CAT itself and future prognosis. CAT also has a profound impact on the patient's family who has similar support needs. It appears that there are several commonalities between UK and Spanish patients, as well as specific local issues. This study justifies expansion of the sampling to other countries.
