RESUMO

Eurocentric physical characteristics, including a thin, tall physique, long straight hair, and fair skin, typify Western beauty standards. Past research indicates that for Black women, greater identification with one's racial/ethnic culture may buffer against internalizing Eurocentric beauty standards, specifically the thin ideal. Black/White Biracial women often experience different appearance pressures from each of their racial identity's sociocultural appearance ideals. Unfortunately, body image research is limited among Bi/Multiracial individuals. Participants were recruited online via Prime Panels, a high-quality data recruitment service provided by CloudResearch. Participants, M(SD)Age= 34.64 (12.85), self-reported their racial/ethnic identification, thin and thick/curvy ideal internalization, and hair and skin tone satisfaction. Using linear regression analyses, we assessed whether racial/ethnic identification buffered against monoracial Black (n = 317) and Black/White Biracial (n = 254) women's thin ideal internalization. Additionally, we assessed whether stronger racial/ethnic identity was associated with stronger thick/curvy ideal internalization and hair and skin tone satisfaction. Supporting hypotheses, greater racial/ethnic identification was associated with higher thick/curvy ideal internalization and hair and skin tone satisfaction among both Black and Biracial women. Contrary to hypotheses, greater racial/ethnic identification was not associated with lower thin ideal internalization in either group. Our results stress the need to use racially and culturally sensitive measurements of body image.

RESUMO

Over 10% of the US population over 12 years old meets criteria for Alcohol Use Disorder (AUD), yet few effective, long-term treatments are currently available. Glycogen synthase kinase 3 beta (GSK3ß) has been implicated in ethanol behaviors and poses as a potential therapeutic target in the treatment of AUD. Here we investigate the role of tideglusib, a selective GSK3ß inhibitor, in ethanol consumption and other behaviors. We have shown tideglusib decreases ethanol consumption in both a model of daily, progressive ethanol intake (two-bottle choice, intermittent ethanol access) and binge-like drinking behavior (drinking-in-the-dark) without effecting water intake. Further, we have shown tideglusib to have no effect on ethanol pharmacokinetics, taste preference, or anxiety-like behavior, though there was a transient increase in total locomotion following treatment. Additionally, we assessed liver health following treatment via serum levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase and showed no effect on aminotransferase levels though there was a decrease in alkaline phosphatase. RNA sequencing studies revealed a role of GSK3ß inhibition via tideglusib on the canonical Wnt signaling pathway, suggesting tideglusib may carry out its effects on ethanol consumption through effects on ß-catenin binding to the transcription factors TCF3 and LEF1. The data presented here further implicate GSK3ß in alcohol consumption and support the use of tideglusib as a potential therapeutic in the treatment of AUD.

RESUMO

BACKGROUND: Benefits of hybrid closed-loop (HCL) systems in a high-risk group with type 1 diabetes and impaired awareness of hypoglycemia (IAH) have not been well-explored. METHODS: Adults with Edmonton HYPO scores ≥1047 were randomized to 26-weeks HCL (MiniMed™ 670G) vs standard therapy (multiple daily injections or insulin pump) without continuous glucose monitoring (CGM) (control). Primary outcome was percentage CGM time-in-range (TIR; 70-180 mg/dL) at 23 to 26 weeks post-randomization. Major secondary endpoints included magnitude of change in counter-regulatory hormones and autonomic symptom responses to hypoglycemia at 26-weeks post-randomization. A post hoc analysis evaluated glycemia risk index (GRI) comparing HCL with control groups at 26 weeks post-randomization. RESULTS: Nine participants (median [interquartile range (IQR)] age 51 [41, 59] years; 44% male; enrolment HYPO score 1183 [1058, 1308]; Clarke score 6 [6, 6]; n = 5 [HCL]; n = 4 [control]) completed the study. Time-in-range was higher using HCL vs control (70% [68, 74%] vs 48% [44, 50%], P = .014). Time <70 mg/dL did not differ (HCL 3.8% [2.7, 3.9] vs control 6.5% [4.3, 8.6], P = .14) although hypoglycemia episode duration was shorter (30 vs 50 minutes, P < .001) with HCL. Glycemia risk index was lower with HCL vs control (38.1 [30.0, 39.2] vs 70.8 [58.5, 72.4], P = .014). Following 6 months of HCL use, greater dopamine (24.0 [12.3, 27.6] vs -18.5 [-36.5, -4.8], P = .014), and growth hormone (6.3 [4.6, 16.8] vs 0.5 [-0.8, 3.0], P = .050) responses to hypoglycemia were observed. CONCLUSIONS: Six months of HCL use in high-risk adults with severe IAH increased glucose TIR and improved GRI without increased hypoglycemia, and partially restored counter-regulatory responses.

RESUMO

BACKGROUND AND AIMS: Microscopic colitis (MC) is a common cause of chronic diarrhea; however, the clinical course of this disease is poorly understood. We aimed to investigate how patients diagnosed with MC were treated in routine clinical practice and how their symptoms compared to patients with other causes of chronic diarrhea at one year follow-up. METHODS: We conducted a case-control study of patients undergoing outpatient colonoscopy to evaluate diarrhea. The study pathologist determined whether patients were classified as MC cases or non-MC controls. One year after colonoscopy, we interviewed cases (n = 74) and controls (n = 162) about their diagnosis, medications for diarrhea, and symptom burden. RESULTS: At 1-year follow-up after colonoscopy, 10% of MC cases were unaware of the diagnosis, 60% had been prescribed a medication for diarrhea, 40% had fecal urgency, 32% had weight loss, and 21% had fecal incontinence. Among cases, 46% were treated with budesonide. Compared to cases, controls had worse symptoms based on the Microscopic Colitis Disease Activity Index score with a median score of 3.0 (interquartile range 1.9-4.2) vs 2.3 (interquartile range 1.4-3.2) at 1-year follow-up. Controls had more frequent stools, urgency, fecal incontinence, and abdominal pain. CONCLUSION: In a cohort of patients with biopsy-confirmed MC and diarrhea controls, we found that some cases remained unaware of their diagnosis, many cases had persistent symptoms, and controls had worse symptoms than cases. These findings suggest there are opportunities to improve management of this chronic disease.

RESUMO

BACKGROUND & AIMS: Colonoscopy often is recommended after an episode of diverticulitis to exclude missed colorectal cancer (CRC). This is a controversial recommendation based on limited evidence. We estimated the prevalence and odds of CRC and advanced colorectal neoplasia on colonoscopy in patients with diverticulitis compared with CRC screening. METHODS: Using data from the Gastrointestinal Quality Improvement Consortium registry, we performed a cross-sectional study with patients ≥40 years old undergoing outpatient colonoscopy for an indication of diverticulitis follow-up evaluation or CRC screening. The primary outcome was CRC. The secondary outcome was advanced colorectal neoplasia. Odds ratios (ORs) and 95% CIs were calculated. RESULTS: We identified 4,591,921 outpatient colonoscopies performed for screening and 91,993 colonoscopies for diverticulitis follow-up evaluation. CRC prevalence was 0.33% in colonoscopies for screening and 0.31% in colonoscopies for diverticulitis. Compared with screening, patients with diverticulitis were less likely to have CRC (adjusted OR, 0.84; 95% CI, 0.74-0.94). CRC prevalence decreased to 0.17% in colonoscopies performed for diverticulitis only. Compared with screening, patients with diverticulitis as the only indication were less likely to have CRC (adjusted OR, 0.49; 95% CI, 0.36-0.68). CRC prevalence increased to 1.43% in patients with complicated diverticulitis. Compared with screening, patients with complicated diverticulitis were more likely to have CRC (adjusted OR, 3.57; 95% CI, 1.59-8.01). CONCLUSIONS: The risk of CRC cancer is low in most patients with diverticulitis. Patients with complicated diverticulitis are the exception. Our results suggest that colonoscopy to detect missed CRC should include diverticulitis patients with a complication and those not current with CRC screening.

RESUMO

INTRODUCTION: Researchers have traditionally tested the benefits of social support, showing that it promotes positive health outcomes. There is a lack of research assessing the deleterious impact of poor social support. Low familial support can serve as a stressor in the lives of adolescents, ultimately fostering negative emotions and maladaptive coping, such as attempted suicide. METHODS: Guided by general strain theory, this study uses two waves of data from the National Study of Adolescence to Adult Health (N = 13,827; n = 7105 for females, n = 6722 for males) to test the effect of low familial support on depressive symptomatology and whether the latter mediates the effect of low familial support on suicide attempt for both males and females. RESULTS: The analyses reveal that low familial support is positively and significantly associated with depressive symptomatology for male and female adolescents. Regarding suicide attempt, adolescents with lower levels of familial support and higher depressive symptomatology were likely to report attempting suicide. Contrary to theoretical expectations, depressive symptomatology did not mediate the relationship between low familial support and suicide attempt. CONCLUSIONS: Overall, the results provide justification for efforts to provide resources to adolescents who lack familial support.

RESUMO

BACKGROUND AND AIM: Food/environmental allergens have been associated with eosinophilic esophagitis (EoE); however, the correlation between allergy profiles and disease responsiveness to proton pump inhibitor (PPI) therapy remains unclear. We aimed to assess the association between food/environmental allergies identified on allergen testing and histologic response to PPI in patients with treatment-naive EoE. METHODS: Adults with newly diagnosed EoE who underwent formal testing for food/environmental allergies at a tertiary center were included. All patients underwent twice-daily PPI for 8 weeks with subsequent repeat endoscopy and biopsy to assess histologic response. Patients with <15 eosinophils/hpf on post-PPI mucosal biopsies were classified as responders (PPI-r-EoE), while those with ≥15 eosinophils/hpf were nonresponders (PPI-nr-EoE). RESULTS: Sixty-one patients met inclusion criteria (21 PPI-r-EoE vs 40 PPI-nr-EoE). Demographic, clinical, and endoscopic finding variables were similar between groups. Positive food allergen test was more prevalent among PPI-nr-EoE patients (82.5% vs 42.9%, P = 0.003). On multivariable analysis, positive food allergen testing remained an independent predictor for PPI nonresponse (aOR 0.15, CI: 0.04-0.58, P = 0.0006). Positive environmental allergen testing was highly prevalent, with no significant differences between groups (77.5% vs 95.2%, P = 0.14). However, higher number of positive environmental allergens (23.3% [≥5 allergens] vs 73.3% [<5 allergens], P = 0.003) and specific aeroallergens correlated with PPI-nr-EoE. CONCLUSION: Positive food allergy testing and increased environmental allergens predicted lower likelihood of histologic response to PPI in EoE. Our findings support an allergic phenotype of EoE that may less likely respond to PPI therapy. Formal allergen testing may play a role in therapy selection and tailored management in EoE.

RESUMO

GOALS: To assess the predictive value of baseline peripheral absolute eosinophil counts (AECs) for proton pump inhibitor (PPI) response in eosinophilic esophagitis (EoE). BACKGROUND: PPI leads to histologic remission in ~50% of EoE patients, although there are few distinguishing clinical features between PPI-responsive (PPI-r-EoE) and nonresponsive (PPI-nr-EoE) diseases. Peripheral eosinophilia is present in ~50% of EoE cases and is associated with eosinophil density on esophageal biopsy and worse clinical outcomes. The association between peripheral eosinophilia and PPI-responsiveness in EoE remains unclear. STUDY: This is a retrospective cohort study of adult EoE patients at a tertiary center between 2012 and 2016. All patients underwent twice daily PPI trials for ≥8 weeks followed by repeat esophageal biopsies and were classified as PPI-r-EoE or PPI-nr-EoE based on histologic response (<15 eosinophils/high power field). Baseline peripheral AEC was obtained within 1 month before index endoscopy. Analyses were performed using Fisher exact/Student t test (univariate) and logistic regression (multivariable). RESULTS: One hundred eighty-three patients (91 PPI-nr-EoE and 92 PPI-r-EoE) were included. Mean peripheral AEC was higher among PPI-nr-EoE patients (0.41 vs 0.24 K/µL, P = 0.013). Baseline peripheral eosinophilia (>0.5 K/µL) was more prevalent among patients with PPI-nr-EoE (70.4% vs 45.5%, P = 0.023) and a history of food impaction (51.9% vs 23.7%, P = 0.0082). On multivariable analyses, peripheral eosinophilia remained an independent predictor for PPI response (adjacent odds ratio = 2.86, CI: 1.07-7.62, P = 0.036) and food impaction (adjacent odds ratio = 2.80, CI: 1.07-7.35, P = 0.037). CONCLUSIONS: Baseline peripheral eosinophilia independently predicts PPI nonresponse and food impaction in EoE patients. Peripheral AEC may help therapy selection in EoE and prevent delays in achieving histologic remission.

RESUMO

BACKGROUND AND AIMS: Guidelines recommend emergent or urgent EGD for esophageal food impaction (EFI), but data on how time to EGD impacts the risk of adverse events remain limited. We determined whether EFI-to-EGD time was associated with adverse events. METHODS: In this retrospective cohort study of patients with endoscopically confirmed EFI, adverse events were classified as esophageal (mucosal tear, bleeding, perforation) or extraesophageal (aspiration, respiratory compromise, hypotension, arrhythmia). Esophageal perforation and extraesophageal adverse events requiring intensive care unit admission were classified as serious adverse events. Baseline characteristics, event details, and procedural details were compared between patients with and without adverse events. Multivariable logistic regression was performed to assess for an association between EFI-to-EGD time and adverse events. RESULTS: Of 188 patients with EFI, 22 (12%) had any adverse event and 2 (1%) had a serious adverse event. Patients with adverse events were older and more likely to have an esophageal motility disorder, to tolerate secretions at presentation, and to have a higher American Society of Anesthesiologists score. EFI-to-EGD time was similar in those with and without adverse events. On multivariable analysis, EFI-to-EGD time was not associated with adverse events (odds ratio, 1.00 [95% confidence interval, .97-1.04] for 1-hour increments; odds ratio, 1.03 [95% confidence interval, .86-1.24] for 6-hour increments). Results were similar after stratifying by eosinophilic esophagitis status and after adjusting for possible confounders. CONCLUSIONS: Because the time from EFI to EGD is not associated with adverse events, emergent EGD for EFI may be unnecessary, and other considerations may determine EGD timing.

RESUMO

INTRODUCTION: Differences in eosinophilic esophagitis (EoE) presentation and outcomes by ethnicity or race remain understudied. We aimed to determine whether EoE patients of Hispanic/Latinx ethnicity or non-White race have differences in presentation at diagnosis or response to topical corticosteroid (tCS) treatment. METHODS: This retrospective cohort study included subjects of any age with a new diagnosis of EoE and documentation of ethnicity or race. For those who had treatment with tCS and follow-up endoscopy/biopsy, we assessed histologic response (<15 eosinophils/hpf), global symptom response, and endoscopic response. Hispanic EoE patients were compared with non-Hispanics at baseline and before and after treatment. The same analyses were repeated for White vs non-Whites. RESULTS: Of 1,026 EoE patients with ethnicity data, just 23 (2%) were Hispanic. Most clinical features at presentation were similar to non-Hispanic EoE patients but histologic response to tCS was numerically lower (38% vs 57%). Non-White EoE patients (13%) were younger at diagnosis and had less insurance, lower zip code-level income, shorter symptom duration, more vomiting, less dysphagia and food impaction, fewer typical endoscopic features, and less dilation. Of 475 patients with race data treated with tCS, non-Whites had a significantly lower histologic response rate (41% vs 59%; P = 0.01), and odds of histologic response remained lower after controlling for potential confounders (adjusted odds ratio 0.40, 95% confidence intervals: 0.19-0.87). DISCUSSION: Few EoE patients at our center were Hispanic, and they had similar clinical presentations as non-Hispanics. The non-White EoE group was larger, and presentation was less dysphagia-specific. Non-White patients were also less than half as likely to respond to tCS.

RESUMO

AIMS: To examine the psychometric properties of the Diabetes Management Experiences Questionnaire (DME-Q). Adapted from the validated Glucose Monitoring Experiences Questionnaire, the DME-Q captures satisfaction with diabetes management irrespective of treatment modalities. METHODS: The DME-Q was completed by adults with type 1 diabetes as part of a randomized controlled trial comparing hybrid closed loop (HCL) to standard therapy. Most psychometric properties were examined with pre-randomization data (n = 149); responsiveness was examined using baseline and 26-week follow-up data (n = 120). RESULTS: Pre-randomization, participants' mean age was 44 ± 12 years, 52% were women. HbA1c was 61 ± 11 mmol/mol (7.8 ± 1.0%), diabetes duration was 24 ± 12 years and 47% used an insulin pump prior to the trial. A forced three-factor analysis revealed three expected domains, that is, 'Convenience', 'Effectiveness' and 'Intrusiveness', and a forced one-factor solution was also satisfactory. Internal consistency reliability was strong for the three subscales ( α range = 0.74-0.84) and 'Total satisfaction' ( α = 0.85). Convergent validity was demonstrated with moderate correlations between DME-Q 'Total satisfaction' and diabetes distress (PAID: rs = -0.57) and treatment satisfaction (DTSQ; rs = 0.58). Divergent validity was demonstrated with a weak correlation with prospective/retrospective memory (PRMQ: rs = -0.16 and - 0.13 respectively). Responsiveness was demonstrated, as participants randomized to HCL had higher 'Effectiveness' and 'Total satisfaction' scores than those randomized to standard therapy. CONCLUSIONS: The 22-item DME-Q is a brief, acceptable, reliable measure with satisfactory structural and construct validity, which is responsive to intervention. The DME-Q is likely to be useful for evaluation of new pharmaceutical agents and technologies in research and clinical settings.

RESUMO

BACKGROUND: Patients with obesity often report esophageal symptoms, with abnormal reflux and esophageal motility suggested as potential mechanisms. However, prior studies showed varying results, often limited by study design/size and esophageal function/symptom measures utilized. We aimed to examine the relationship between obesity and objective esophageal function testing and patient-reported outcomes, utilizing prospective symptom, manometric and reflux monitoring data with impedance. METHODS: Adults referred for high-resolution impedance-manometry (HRiM) and multichannel intraluminal impedance-pH monitoring (MII-pH) to evaluate esophageal symptoms were enrolled. Validated symptom and health-related quality of life (HR-QOL) instruments were prospectively collected: GERDQ, reflux symptoms index (RSI), dominant symptom intensity (DSI, multiplied 5-point Likert scales for symptom frequency/severity), global symptom severity (GSS, 100-point visual analog scale), and Short Form-12 (SF-12) for HR-QOL. Esophageal function testing measures were compared across body mass index (BMI) categories and correlated with patient-reported outcomes. KEY RESULTS: Seven hundred and fifty four patients were included (Normal:281/Overweight:253/Class I obesity:137/Class II/III obesity:83). Reflux burden measures on MII-pH (acid exposure time, total reflux episodes, bolus exposure time), conclusive pathologic reflux (Lyon), and hiatal hernia were increased in higher obesity classes compared to normal BMI. Class II/III obesity was associated with more normal/hypercontractile swallows, less ineffective swallows, and better bolus transit on HRiM. BMI correlated positively with GERDQ/RSI/DSI/GSS, and negatively with physical component score (SF-12). Esophageal symptom severity and HR-QOL correlated strongly with MII-pH findings, but not HRiM measures. CONCLUSIONS/INFERENCES: Obesity is associated with increased esophageal symptom burden and worse physical HR-QOL, which correlate with higher acid/bolus reflux burden but not altered esophageal motility/transit/contractile reserve.

RESUMO

BACKGROUND: The presentation of eosinophilic esophagitis (EoE) is heterogeneous, but trends over time are not known. AIM: To determine whether clinical and endoscopic phenotypes at EoE diagnosis have changed over the past 2 decades. METHODS: In this retrospective cohort study, adults and children with newly diagnosed EoE were phenotyped as follows: (1) inflammatory vs fibrostenotic vs mixed on endoscopy; (2) atopic vs non-atopic; (3) age at symptom onset; (4) age at diagnosis; (5) presence of autoimmune or connective tissue disease; and (6) responsive to steroids. The prevalence of different phenotypes was categorized by 5-year intervals. Multivariate analysis was performed to assess for changes in patient features over time. RESULTS: Of 1187 EoE patients, age at diagnosis increased over time (from 22.0 years in 2002-2006 to 31.8 years in 2017-2021; p < 0.001) as did the frequency of dysphagia (67% to 92%; p < 0.001). Endoscopic phenotypes were increasingly mixed (26% vs 68%; p < 0.001) and an increasing proportion of patients had later onset of EoE. However, there were no significant trends for concomitant autoimmune/connective tissue disease or steroid responder phenotypes. On multivariate analysis, after accounting for age, dysphagia, and food impaction, the increase in the mixed endoscopic phenotype persisted (aOR 1.51 per each 5-year interval, 95% CI 1.31-1.73). CONCLUSION: EoE phenotypes have changed over the past two decades, with increasing age at diagnosis and age at symptom onset. The mixed endoscopic phenotype also increased, even after controlling for age and symptomatology. Whether this reflects changes in provider recognition or disease pathophysiology is yet to be elucidated.

RESUMO

OBJECTIVES: Feeding tubes can provide a temporary or long-term solution for nutritional therapy. Little is known regarding the use of feeding tubes in patients with eosinophilic esophagitis (EoE). We sought to describe the characteristics and outcomes in EoE patients requiring tube feeding. METHODS: This was a retrospective cohort study of EoE patients at a large tertiary care health system. Demographics, clinical characteristics, and endoscopic findings were extracted from medical records, and patients who had a feeding tube were identified. Patients with and without a feeding tube were compared. Details about the tube, complications, and treatment were extracted. Growth, global symptomatic, endoscopic, and histopathologic (<15 eos/hpf) responses were compared before and after the initiation of feeding tube therapy. RESULTS: We identified 39 of 1216 EoE patients who had a feeding tube (3%). Feeding tube patients were younger (mean age 6.3 years), reported more vomiting, and had a lower total endoscopic reference score than non-feeding tube patients ( P < 0.01 for all). Tubes were used for therapy for an average of 6.8 years, with most patients (95%) receiving both pharmacologic and formula treatment for EoE. An emergency department visit for a tube complication was required in 26%. Tube feeding improved body mass index z score ( P < 0.01), symptomatic response (42%), endoscopic response (53%), and histologic response (71%). CONCLUSIONS: Among EoE patients, only a small subset required a feeding tube and predominantly were young children with failure to thrive. Feeding tubes significantly improved growth and, when used in combination with other treatments, led to reduced esophageal eosinophilic inflammation.

RESUMO

Neuroblastoma is a complex and aggressive type of cancer that affects children. Current treatments involve a combination of surgery, chemotherapy, radiotherapy, and stem cell transplantation. However, treatment outcomes vary due to the heterogeneous nature of the disease. Computational models have been used to analyse data, simulate biological processes, and predict disease progression and treatment outcomes. While continuum cancer models capture the overall behaviour of tumours, and agent-based models represent the complex behaviour of individual cells, multiscale models represent interactions at different organisational levels, providing a more comprehensive understanding of the system. In 2018, the PRIMAGE consortium was formed to build a cloud-based decision support system for neuroblastoma, including a multi-scale model for patient-specific simulations of disease progression. In this work we have developed this multi-scale model that includes data such as patient's tumour geometry, cellularity, vascularization, genetics and type of chemotherapy treatment, and integrated it into an online platform that runs the simulations on a high-performance computation cluster using Onedata and Kubernetes technologies. This infrastructure will allow clinicians to optimise treatment regimens and reduce the number of costly and time-consuming clinical trials. This manuscript outlines the challenging framework's model architecture, data workflow, hypothesis, and resources employed in its development.

RESUMO

OBJECTIVE: To examine differences in sleep disturbance, nocturia, and depression among adults with overactive bladder (OAB) by treatment type. METHODS: A cross-sectional survey of adults with OAB assessed sleep disturbance, nocturia, and depression using patient-reported outcome measures, including the Patient Reported Outcomes Measurement Information System (PROMIS)-29 Profile v2.1 (Sleep Disturbance and Depression domains), Lower Urinary Tract Dysfunction Research Network Symptom Index-10, and PROMIS Sleep Disturbance Short Form 8B. Treatment groups included antimuscarinics, ß-3 adrenergic agonists, and no treatment. Analysis of covariance (ANCOVA) was used to test for differences in study endpoints; Bonferroni-adjusted pairwise tests (P < .05/3) were performed to compare differences in least squares means between groups. RESULTS: One hundred participants were included per treatment group. The overall mean (standard deviation) age across all groups was 47.8 (11.8) years. Symptom scores across all PROMIS domains in all three treatment groups were higher than the US general population. There were no statistically significant differences in outcomes across treatment groups. CONCLUSION: Adults with OAB reported being affected by sleep disturbance and depression, regardless of treatment. The mirabegron group trended toward the lowest symptom impact across all outcomes, however, comparisons were not significant. Future research should examine temporal associations between OAB treatment, sleep disturbance, and outcomes.

RESUMO

BACKGROUND: Malignant spinal cord compression (MSCC) has been noted in 3-5% of children with primary tumours. MSCC can be associated with permanent neurological deficits and prompt treatment is necessary. Our aim was to perform a systematic review on MSCC in children < 18 years to help formulate national guidelines. METHODS: A systematic review of the English language was undertaken using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Search criteria included 'MSCC in children, paediatric and metastases' for papers published between January1999 and December 2022. Isolated case reports/case series with < 10 patients were excluded. RESULTS: From a total of 17 articles identified, a final 7 were analysed (Level III/IV). Neuroblastoma constituted the most common cause for MSCC in children (62.7%) followed by sarcoma (14.2%). Soft tissue sarcomas were the most frequent cause of MSCC in children > 5 years old, while for neuroblastomas, the mean age of presentation was 20 months. The median age at time of diagnosis for the entire cohort of patients was 50.9 months (14.8-139). The median follow-up duration was 50.7 months (0.5-204). Motor deficits were the presenting symptom in 95.6% of children followed by pain in 65.4% and sphincter disturbance in 24%. There was a delay of about 26.05 days (7-600) between the onset of symptoms and diagnosis. A multimodality approach to treatment was utilised depending on the primary tumour. The prognosis for neurological recovery was found to be inversely proportional to the degree of neurological deficits and duration of symptoms in four studies. CONCLUSION: Neuroblastoma is the most common cause for MSCC in children (62.7%) followed by sarcoma (14.2%), whilst soft tissue sarcomas constituted the most frequent cause of MSCC in children > 5 years old. The majority of patients presented with motor deficit, followed by pain. In children with neuroblastoma /lymphoma, chemotherapy was the primary treatment. Early surgery should be a consideration with rapid deterioration of neurology despite chemotherapy. A multimodality approach including chemo-radiotherapy and surgery should be the treatment of choice in metastatic sarcomas. It is worth noting that multi-level laminectomy/decompression and asymmetrical radiation to the spine can lead to spinal column deformity in the future.

RESUMO

Objective: Focusing on body functionality - what the body can do - may benefit women's body image. This pilot study examined the effects of focusing on body functionality appreciation during an audio-guided mirror gazing task (F-MGT). Participants: 101 college women, M(SD)AGE = 19.49(1.31), were alternately assigned to F-MGT or a comparison with no guidance on how to examine the body, directed attention mirror gazing task (DA-MGT). Methods: Participants self-reported pre- and post-MGT body appreciation, state appearance satisfaction, and orientation to and satisfaction with physical functionality. Results: Group interactions were significant for body appreciation and functionality orientation. DA-MGT decreased body appreciation from pre- to post-MGT; F-MGT did not change. There were no significant interactions in post-MGT state appearance satisfaction or functionality satisfaction, though state appearance satisfaction increased significantly in F-MGT. Conclusions: Integrating body functionality may buffer against harmful effects of mirror gazing. Given F-MGT's brevity, additional work must assess its potential as an intervention technique.

RESUMO

The application of engineered biomaterials for wound healing has been pursued since the beginning of tissue engineering. Here, we attempt to apply functionalized lignin to confer antioxidation to the extracellular microenvironments of wounds and to deliver oxygen from the dissociation of calcium peroxide for enhanced vascularization and healing responses without eliciting inflammatory responses. Elemental analysis showed 17 times higher quantity of calcium in the oxygen-releasing nanoparticles. Lignin composites including the oxygen-generating nanoparticles released around 700 ppm oxygen per day at least for 7 days. By modulating the concentration of the methacrylated gelatin, we were able to maintain the injectability of lignin composite precursors and the stiffness of lignin composites suitable for wound healing after photo-cross-linking. In situ formation of lignin composites with the oxygen-releasing nanoparticles enhanced the rate of tissue granulation, the formation of blood vessels, and the infiltration of α-smooth muscle actin+ fibroblasts into the wounds over 7 days. At 28 days after surgery, the lignin composite with oxygen-generating nanoparticles remodeled the collagen architecture, resembling the basket-weave pattern of unwounded collagen with minimal scar formation. Thus, our study shows the potential of functionalized lignin for wound-healing applications requiring balanced antioxidation and controlled release of oxygen for enhanced tissue granulation, vascularization, and maturation of collagen.
