RESUMEN

OBJECTIVES: Social determinants of health (SDOH) (healthcare access and quality, education access and quality, socioeconomic status, social and cultural context, neighborhood and built environment) ( Healthy People 2030 ) have been shown to impact a wide range of health-related outcomes and access to care. Given the medical and nonmedical costs associated with children with unilateral hearing loss (UHL), the varied insurance coverage for hearing healthcare services, and the differences in hearing aid utilization rates between children of different sociodemographic classes, the sociodemographic information of children with UHL enrolled in research studies should be collected to ensure the generalizability of hearing healthcare interventions. Therefore, the objective of this scoping review is to assess the reporting of SDOH data for participants in studies of pediatric UHL and its comparison to population trends. DESIGN: Two searches of published literature were conducted by a qualified medical librarian. Two reviewers then evaluated all candidate articles. Study inclusion parameters were from 2010 to present, peer-reviewed studies with prospective study design, and participant population including children (age 0 to 18 years old) with UHL. RESULTS: Two literature searches using PubMed Medline and Embase found 442 and 3058 studies each for review. After abstract and paper review, 87 studies were included in final qualitative review, with 22 of these studies reporting race distribution of participants, 15 reporting insurance status or family income, and 12 reporting the maternal education level. CONCLUSIONS: Sociodemographic data are not commonly reported in research studies of children with UHL. In reported samples, research participants are more likely to have private insurance and higher family income compared with overall population distribution. These demographic biases may affect the generalizability of study results to all children with UHL. Further evaluation is warranted to evaluate whether participant recruitment affects outcomes that reflect the overall population.

RESUMEN

OBJECTIVE: To investigate the fatigue levels of children with hearing loss (HL) and obstructive sleep apnea (OSA), hypothesizing that the fatigue experienced by children with HL is under-recognized. STUDY DESIGN: Cross-sectional survey. METHODS: We identified children aged 2-18 with HL, OSA, sleep-disordered breathing (SDB), and controls from a pediatric otolaryngology clinic and sleep center. Children and/or parents completed the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL MFS), Hearing Environments And Reflection on Quality of Life (HEAR-QL), and OSA-18. RESULTS: Responses of 50 children with HL, 79 with OSA, and 18 with SDB were compared with those of 49 recruited controls (RC) and literature controls (LC). Children with HL or OSA had higher fatigue than controls in the PedsQL MFS self-reported (HL 65.4, OSA 54.7, RC 71.8, LC 80.5, p < 0.001) and parent-reported (HL 64.6, OSA 59.3, RC 75.2, LC 89.6, p < 0.001). Children with HL had Cognitive Fatigue similar to that of children with OSA (self 60.4 vs. 49.5, p = 0.170; parent 56.0 vs. 56.7, p = 0.998), though with decreased Sleep/Rest Fatigue (self 67.8 vs. 56.3, p = 0.033; parent 69.8 vs. 57.5, p = 0.001). Children with HL or OSA had lower disease-related quality of life (QOL) than controls in the HEAR-QL and OSA-18, respectively. Stratification with disease severity revealed no differences in fatigue. CONCLUSION: Children with HL or OSA experience higher fatigue and lower QOL than controls. Similar Cognitive Fatigue in both groups suggests under-recognized fatigue in children with HL.

RESUMEN

The association between fatty acids and prostate cancer remains poorly explored in African-descent populations. Here, we analyze 24 circulating fatty acids in 2934 men, including 1431 prostate cancer cases and 1503 population controls from Ghana and the United States, using CLIA-certified mass spectrometry-based assays. We investigate their associations with population groups (Ghanaian, African American, European American men), lifestyle factors, the fatty acid desaturase (FADS) genetic locus, and prostate cancer. Blood levels of circulating fatty acids vary significantly between the three population groups, particularly trans, omega-3 and omega-6 fatty acids. FADS1/2 germline genetic variants and lifestyle factors explain some of the variation in fatty acid levels, with the FADS1/2 locus showing population-specific associations, suggesting differences in their control by germline genetic factors. All trans fatty acids, namely elaidic, palmitelaidic, and linoelaidic acids, associated with an increase in the odds of developing prostate cancer, independent of ancestry, geographic location, or potential confounders.

RESUMEN

OBJECTIVE: The parent-proxy Preschool HEAR-QL (Hearing Environments And Reflections on Quality of Life) is a quality of life (QOL) measure for 2 to 6-year-old children with hearing loss (HL). We compared Preschool HEAR-QL scores for children with HL and children with normal hearing (NH) to examine the measure's discriminant validity. STUDY DESIGN: Cross-sectional study. SETTING: Three tertiary care pediatric otolaryngology clinics. PATIENTS: Two hundred forty-eight parents of children 2 to 6 years old with NH or HL participated. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The Preschool HEAR-QL has five domains: Behavior and Attention, Hearing Environments, New Social Situations, Social Interactions, and Communications. Scores range from 0 to 100; higher scores indicate higher QOL. Scores for children with NH and with HL were compared using analysis of variance (ANOVA) and area under the receiver operating characteristic (AUROC) curves. RESULTS: Total HEAR-QL mean (SD) scores were higher for children with NH compared to children with HL (75.7 [10.5] vs. 67.5 [15.5], p < 0.001). Scores were not significantly different between children with unilateral and bilateral HL. Children 2 to 4 years old received lower Communications-domain scores than children 4 to 6 years old across all children (63.7 [25.4] vs. 74.1 [24.3], p = 0.01) and within the HL cohort (61.3 [25.1] vs. 72.6 [25.3]; p = 0.009). The Hearing Environments domain displayed excellent discrimination (AUROC = 0.858); other domains showed little to no discrimination. CONCLUSIONS: The Hearing Environments-domain of the Preschool HEAR-QL differentiated between children with and without HL. Children with NH had higher scores than children with HL on both Total HEAR-QL and Hearing Environment-domain scores.

RESUMEN

BACKGROUND: Previous research has revealed links between air pollution exposure and metabolic syndrome in adults; however, these associations are less explored in children. OBJECTIVE: This study aims to investigate the association between traffic-related air pollutants (TRAP) and biomarkers of metabolic dysregulation, oxidative stress, and lung epithelial damage in children. METHODS: We conducted cross-sectional analyses in a sample of predominantly Latinx, low-income children (n = 218) to examine associations between air pollutants (nitrogen dioxide (NO2), nitrogen oxides (NOx), elemental carbon, polycyclic aromatic hydrocarbons, carbon monoxide (CO), fine particulates (PM2.5)) and biomarkers of metabolic function (high-density lipoprotein (HDL), hemoglobin A1c (HbA1c), oxidative stress (8-isoprostane), and lung epithelial damage (club cell protein 16 (CC16)). RESULTS: HDL cholesterol showed an inverse association with NO2 and NOx, with the strongest relationship between HDL and 3-month exposure to NO2 (-15.4 mg/dL per IQR increase in 3-month NO2, 95% CI = -27.4, -3.4). 8-isoprostane showed a consistent pattern of increasing values with 1-day and 1-week exposure across all pollutants. Non-significant increases in % HbA1c were found during 1-month time frames and decreasing CC16 in 3-month exposure time frames. CONCLUSION: Our results suggest that TRAP is significantly associated with decreased HDL cholesterol in longer-term time frames and elevated 8-isoprostane in shorter-term time frames. TRAP could have the potential to influence lifelong metabolic patterns, through metabolic effects in childhood.

RESUMEN

There is evidence that tumor immunobiology and immunotherapy response may differ between African American and European American prostate cancer patients. Here, we determine if men of African descent harbor a unique systemic immune-oncological signature and measure 82 circulating proteins in almost 3000 Ghanaian, African American, and European American men. Protein signatures for suppression of tumor immunity and chemotaxis are elevated in men of West African ancestry. Importantly, the suppression of tumor immunity protein signature associates with metastatic and lethal prostate cancer, pointing to clinical importance. Moreover, two markers, pleiotrophin and TNFRSF9, predict poor disease survival specifically among African American men. These findings indicate that immune-oncology marker profiles differ between men of African and European descent. These differences may contribute to the disproportionate burden of lethal prostate cancer in men of African ancestry. The elevated peripheral suppression of tumor immunity may have important implication for guidance of cancer therapy which could particularly benefit African American patients.

RESUMEN

OBJECTIVE: We explored whether children with hearing loss (HL) and their parents perceive the child's quality of life (QOL) similarly using the Hearing Environment And Reflections on Quality of Life (HEAR-QL) survey. STUDY DESIGN: Cross-sectional study. SETTING: Pediatric otolaryngology clinic. PATIENTS: 7 to 14 year old children with unilateral or bilateral HL and their parents. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The HEAR-QL is a validated hearing-related QOL survey and has three domains and total score, ranging from 0 to 100; higher scores indicate higher QOL. RESULTS: HEAR-QL total score (r = 0.520, p = 0.011), Activities (r = 0.608, p = 0.002), and Feelings (r = 0.657, p = 0.001) domains correlated strongly, but the hearing Environments domain (r = 0.291, p = 0.178) correlated weakly. Children with mild HL scored total and Environments domains lower than their parents (mean difference [MD] -13.9 [95% CI -34.3, 6.6] and -19.2 [95% CI -41.2, 2.7]; Hedge's g 0.67, 0.77, respectively) compared to children with moderate-to-severe HL (moderate HL MD 8.3 [95% CI -15.7, 32.4] and 13.1 [95% CI -25.2, 51.5]; severe HL MD 9.5 [95% CI 0.6, 18.4] and 14.4 [95% CI 4.3, 24.6]). DISCUSSION: Children and their parents correlated strongly on observable Feelings And Activities domains scores but correlated weakly on hearing difficulty in Environments scores. Parents of children with mild HL perceived their children's QOL to be better than the children themselves, differing from the moderate-to-severe HL groups.

RESUMEN

Autoimmune diabetes is a rare but severe endocrine toxicity induced by immune checkpoint inhibitor (ICI) treatment. It is unclear if ICI causes selective islet toxicity or non-selective pancreas toxicity. We analyzed 11 patients treated with ICI who developed ICI-related autoimmune diabetes. Eight patients had lipase and/or amylase tested on the same day of diagnosis of autoimmune diabetes. Among them, 75% (6/8) had normal lipase and 100% (6/6) had normal amylase. There was no correlation between glucose level at onset and biochemical pancreatitis. We characterized the clinical features of ICI-induced autoimmune diabetes. Fifty-five percent (6/11) of patients tested positive for GAD65 autoantibodies, and 55% (6/11) developed diabetic ketoacidosis at manifestation of hyperglycemia. In all 11 patients, C-peptide levels were low in the presence of hyperglycemia. ICI-induced thyroiditis was found in 64% (7/11), of which 36% (4/11) were newly diagnosed with thyroiditis while the remaining 27% (3/11) had pre-existing hypothyroidism followed by ICI-induced thyroiditis. Additionally, 27% (3/11), developed ICI-induced hypophysitis. Thyroiditis and autoimmune diabetes coexisted in all patients with ICI-induced hypophysitis. The median time from ICI treatment to the onset of autoimmune diabetes was 11 weeks. Our data suggest that few patients had coexistent ICI-induced autoimmune diabetes and pancreatitis, suggesting ICI mainly caused selective islet toxicity.

RESUMEN

Sesame germplasm harbors genetic diversity which can be useful for sesame improvement in breeding programs. Seven accessions with different levels of oleic acid were selected from the entire USDA sesame germplasm collection (1232 accessions) and planted for morphological observation and re-examination of fatty acid composition. The coding region of the FAD2 gene for fatty acid desaturase (FAD) in these accessions was also sequenced. Cultivated sesame accessions flowered and matured earlier than the wild species. The cultivated sesame seeds contained a significantly higher percentage of oleic acid (40.4%) than the seeds of the wild species (26.1%). Nucleotide polymorphisms were identified in the FAD2 gene coding region between wild and cultivated species. Some nucleotide polymorphisms led to amino acid changes, one of which was located in the enzyme active site and may contribute to the altered fatty acid composition. Based on the morphology observation, chemical analysis, and sequence analysis, it was determined that two accessions were misnamed and need to be reclassified. The results obtained from this study are useful for sesame improvement in molecular breeding programs.
