RESUMO

As currently the most common metabolic disease, type 2 diabetes mellitus (T2DM) has shown a continuous increase in the number of patients in recent decades. Most anti-T2DM drugs tend to cause some side effects. Given the pathogenesis of T2DM, natural products have emerged as an important source of anti-T2DM drugs. This article reviews natural products with potential hypoglycemic activity from 2019 to 2023. A total of 200 previously natural products were discovered on SciFinder, PubMed and Web of Science. These products were categorized based on their structural frameworks and their biological activities were summarized. Although the mechanisms of action of most compounds are unclear, these compounds could still serve as candidates for the development of lead compounds. Therefore, further structure and activity research of natural products will significantly contribute to the development of potential anti-T2DM drugs.

RESUMO

BACKGROUND: Social conditions and dietary behaviors have been implicated in the rising burden of gastrointestinal cancers (GIC). The "food environment" reflects influences on a community level relative to food availability, nutritional assistance, and social determinants of health. Using the US Department of Agriculture-Food Environment Atlas (FEA), we sought to characterize the association of food environment on GIC presenting stage and long-term survival. METHODS: Patients diagnosed with GIC between 2013 and 2017 were identified using the SEER database. FEA-scores were based on 282 county-level food security variables, store-restaurant availability, SNAP/WIC enrollment, pricing/taxes, and producer vicinity adjusted-for factors of socioeconomic status, race-ethnicity, transportation access, and comorbidities. Relative FEA rankings across US counties were averaged into a composite score and assigned to patients by county-of-residence. The association of FEA, cancer stage, and survival were analyzed using multiple logistic regression and cox-proportional hazard models relative to White/non-White race/ethnicity. RESULTS: Among 287,148 patients, the most common GIC-sites were colon (n = 97,942, 34%), pancreas (n = 49,785, 17.3%), liver (n = 31,098, 11.0%) and esophagus (n = 16,271, 5.7%). A worse food environment was independently associated with increased odds of late-stage diagnosis (esophageal odds ratio [OR]: 1.03, 95% confidence interval [CI]: 1.01-1.05; hepatic OR: 1.06, 95% CI: 1.03-1.08; pancreatic OR: 1.04, 95% CI: 1.01-1.06) among all patients; in contrast, food environment was associated with colorectal cancer stage among non-White patients only (OR: 1.04, 95% CI: 1.03-1.06). Worse food environment was associated with worse 3-year survival (colon OR: 1.03, 95% CI: 1.01-1.04; hepatic OR: 1.12, 95% CI: 1.08-1.17; gastric OR: 1.07, 95% CI: 1.01-1.13). Similar associations were noted relative to overall survival among the entire cohort (biliary tract hazard ratio [HR]: 1.03, 95% CI: 1.01-1.05; esophageal HR: 1.02, 95% CI: 1.01-1.04; hepatic HR: 1.07, 95% CI: 1.06-1.09; pancreatic HR: 1.04, 95% CI: 1.02-1.05; rectum HR: 1.03, 95% CI: 1.01-1.04; gastric HR: 1.05, 95% CI: 1.03-1.07), as well as among non-White patients (biliary HR: 1.04, 95% CI: 1.01-1.07; colon HR: 1.03, 95% CI: 1.01-1.05; esophageal HR: 1.05, 95% CI: 1.02-1.08; hepatic HR: 1.08, 95% CI: 1.06-1.10) (all p < 0.003). CONCLUSIONS: Food environment was independently associated with late-stage tumor presentation and worse 3-year and overall survival among GIC patients. Interventions to address inequities across communities relative to food environments are needed to alleviate disparities in cancer care.

RESUMO

Objectives: Online educational platforms with open access have seen a growing adoption in the field of medical education. However, the extent of their global usage is still unclear. To fill this knowledge gap, our objective is to examine the usage patterns of two renowned open-access resources in Otolaryngology. This includes identifying the most sought-after topics and understanding the demographics of their users. Methods: Retrospective study of web analytics data between 2016 and 2021 extracted from the Headmirror.com and Mayo Clinic Otolaryngology YouTube channel platforms analyzing demographic and education topic trends via descriptive, geospatial, time-series, t-tests, and ANOVA analyses. Results: Viewership spanned 124 countries in 7 different geographic regions, with 72 countries comprising low- to middle-income countries, mostly represented ages of 25-34 years old, came from high-income countries rather than low-income (p < .001), and used mobile phones followed by computers for device access. Video-educational material comprised of subspecialty topics on Rhinology and Sinus Surgery (25%) at the highest end and Facial Trauma (1%) at the lowest. Controlling for the age of the video content, the most-accessed videos comprised of subspecialty topics on Head and Neck Surgery at the highest end and Laryngology at the lowest with significant differentiation across topics of interest (p < .044). Conclusions: This assessment of web-analytics platforms from two widely used otolaryngology free, online-access materials showed increasing global usage trends with significant differentiating factors along viewership demographics, as well as sought-after subspecialty topics of interest. In turn, our results not only lay the groundwork for characterizing the global otolaryngology audience but also for future development of targeted educational materials and accessibility initiatives aimed at ameliorating global educational disparities in the field.

RESUMO

BACKGROUND: Salivary gland cancers (SGC)-social determinants of health (SDoH) investigations are limited by narrow scopes of SGC-types and SDoH. This Social Vulnerability Index (SVI)-study hypothesized that socioeconomic status (SES) most contributed to SDoH-associated SGC-disparities. METHODS: Retrospective cohort of 24 775 SGCs assessed SES, minority-language status (ML), household composition (HH), housing-transportation (HT), and composite-SDoH measured by the SVI via regressions with surveillance and survival length, late-staging presentation, and treatment (surgery, radio-, chemotherapy) receipt. RESULTS: Increasing social vulnerability showed decreases in surveillance/survival; increased odds of advanced-presenting-stage (OR: 1.12, 95% CI: 1.07, 1.17), chemotherapy receipt (OR: 1.13, 95% CI: 1.03, 1.23); decreased odds of primary surgery (0.89, 0.84, 0.94), radiotherapy (0.91, 0.85, 0.97, p = 0.003) for SGCs. Trends were differentially correlated with SES, ML, HH, and HT-vulnerabilities. CONCLUSIONS: Through quantifying SDoH-derived SGC-disparities, the SVI can guide targeted initiatives against SDoH that elicit the most detrimental associations for specific sociodemographics.

RESUMO

BACKGROUND: Prior works have studied the impact of social determinants on various cancers but there is limited analysis on eye-orbit cancers. Current literature tends to focus on socioeconomic status and race, with sparse analysis of interdisciplinary contributions. We examined social determinants as measured by the Centers for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI), quantifying eye and orbit melanoma disparities across the United States. METHODS: A retrospective review of 15,157 patients diagnosed with eye-orbit cancers in the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2017 was performed, extracting 6139 ocular melanomas. SVI scores were abstracted and matched to SEER patient data, with scores generated by weighted averages per population density of county's census tracts. Primary outcome was months survived, while secondary outcomes were advanced staging, high grading, and primary surgery receipt. RESULTS: With increased total SVI score, indicating more vulnerability, we observed significant decreases of 23.1% in months survival for melanoma histology (p < 0.001) and 19.6-39.7% by primary site. Increasing total SVI showed increased odds of higher grading (odds ratio [OR] 1.20, 95% confidence interval [CI] 1.02-1.43) and decreased odds of surgical intervention (OR 0.94, 95% CI 0.92-0.96). Of the four themes, higher magnitude contributions were observed with socioeconomic status (26.0%) and housing transportation (14.4%), while lesser magnitude contributions were observed with minority language status (13.5%) and household composition (9.0%). CONCLUSIONS: Increasing social vulnerability, as measured by the CDC SVI and its subscores, displayed significant detrimental trends in prognostic and treatment factors for adult eye-orbit melanoma. Subscores quantified which social determinants contributed most to disparities. This lays groundwork for providers to target the highest-impact social determinant for non-clinical factors in patient care.

RESUMO

OBJECTIVE: To investigate the association of social determinants of health (SDoH) in squamous cell carcinoma of the tongue in the United States and to evaluate the real-world contribution of specific disparities. STUDY DESIGN: Retrospective cohort study. SETTING: United States. METHODS: The Centers for Disease Control and Prevention-Social Vulnerability Index (SVI) and National Cancer Institute-Surveillance, Epidemiology, and End Results Program database were used to study 62,103 adult tongue squamous cell carcinoma patients from 1975 to 2017. Regression analysis assessed trends in months of follow-up and survival across social vulnerability and 4 subcategories of social vulnerability. RESULTS: As overall SVI score increases (increased social vulnerability), there is a significant decrease in the average length of follow-up (22.95% decrease from 63.99 to 49.31 months; P < .001) across patients from the lowest and highest social vulnerability groups. As overall SVI score increases, there is a significant decrease in the average months of survival (28.00% decrease from 49.20 to 35.43 months; P < .001). There is also a significantly greater odds ratio (OR = 1.05; P < .001) of advanced cancer staging upon presentation at higher SVI scores. Patients with higher SVI scores have a lower OR (0.93; P < .001) of receiving surgery as their primary treatment when compared to patients with lower SVI scores. Patients with higher SVI scores also have a significantly greater OR (OR = 1.05; P < .001) of receiving chemotherapy as their primary treatment when compared to patients with lower SVI scores. CONCLUSION: Increased social vulnerability is shown to have a detrimental impact on the treatment and prognosis of patients with squamous cell carcinoma of the tongue.

RESUMO

Background: As thyroid cancer incidence rises, it is increasingly valuable to recognize disparities in treatment and diagnosis. Prior investigations into social determinants of health (SDoH) are limited to pediatric populations or studies looking at single factors such as race or environmental influences. Utilizing the CDC-social vulnerability index and SEER-patient database to assess the amalgamated, real-world influence of varied SDoH and their quantifiable impact on thyroid cancer disparities across the United States. Methods: In a retrospective cohort study, 199,340 adult thyroid cancer patients from 1975 to 2017 were assessed for significant regression trends in months of follow-up/surveillance, survival, late staging, and treatment receipt across thyroid cancer-subtypes with increasing overall social vulnerability, as well as in 15 SDoH variables regarding socioeconomic status, minority-language status, household composition, and housing-transportation across all the U.S. counties while accounting for sociodemographic regional differences. Results: With increasing overall social vulnerability, decreases in months of follow-up were observed with patients with papillary, follicular, medullary, oncocytic, and anaplastic thyroid cancer (p = 0.001). Comparing lowest with highest vulnerability cohorts, relative decreases in months of surveillance ranged from 55.6% (14.5-6.5 months) with anaplastic to 17% (108.6-90.2) with oncocytic. Socioeconomic status vulnerabilities, followed by vulnerabilities in household composition and housing-transportation type, contributed to these overall trends. Similar survival decreases occurred across all thyroid cancer patients, ranging from 55.9% (9.6-4.2) with anaplastic to 28.3% (97-69.5) with oncocytic. Minority-language status vulnerabilities and housing-transportation types largely contributed to these trends. Increasing overall vulnerability was associated with increased odds of advanced staging for papillary (odds ratio [OR] = 1.07 [confidence interval, CI 1.03-1.12]) and decreased odds of indicated treatment via surgery (lowest, medullary: 0.91 [CI 0.84-0.99]), radiation therapy (lowest, anaplastic: 0.88 [CI 0.82-0.93]), and chemotherapy (lowest, oncocytic: 0.81 [CI 0.67-0.98]) were observed. Vulnerabilities in minority-language status and housing-transportation, followed by socioeconomic status vulnerabilities, were differential contributors to these overall vulnerability trends. Conclusions: Our results show significant detriments in thyroid cancer care and prognosis in the United States with increasing overall social vulnerability while identifying which SDoH quantifiably contribute more to disparities in inter-relational, real-world-like contexts.

RESUMO

BACKGROUND: In this study, our objective was to investigate the predictive value of serum and urine fluctuations of neutrophil gelatinase-associated lipid transporters (NGAL) in relation to the progression of chronic kidney disease (CKD) among patients with septic associated AKI (SA-AKI). METHODS: A total of 425 SA-AKI patients were enrolled in this study and divided into the recovery group (n = 320) and the AKI-to-CKD group (n = 105) based on 3-month follow-up data. The serum and urine NGAL levels on the day of AKI diagnosis (T0) and 48 h after anti-AKI treatment (T1) were recorded and calculated. RESULTS: The levels of NGAL in serum and urine were found to be higher in the AKI-to-CKD group compared to the recovery group at T1 point (P < 0.05). The reductions of NGAL at 48 h in serum and urine were lower in the AKI-to-CKD group than those observed in the recovery group (P < 0.05). In comparison to T0, a significant decrease was noted for both serum and urine NGAL levels on T1 among patients who recovered from AKI (P < 0.05), whereas no such trend was observed among those with AKI-to-CKD transition (P > 0.05). After adjusting age, sex, and BMI through partial correlation analysis, the reduction of serum NGAL was found to be most strongly associated with the transition from AKI to CKD. ROC analysis showed an AUC of 0.832 for serum NGAL reduction, with a cut-off value of - 111.24 ng/ml and sensitivity and rates of 76.2% and 81.2%, respectively. Logistic regression analysis indicated that a reduction of serum NGAL ≥ - 111.24 ng/ml was the early warning indicator for the progression of CKD in SA-AKI patients. CONCLUSION: The reduction of serum NGAL following 48 h of anti-AKI therapy represents a distinct hazard factor for the advancement of CKD in patients with SA-AKI, independent of other variables.

RESUMO

OBJECTIVES: Studies addressing social determinants of health (SDH) in head-neck melanomas (HNM) have only assessed incidence with increasing socioeconomic status. None have investigated a wider scope of SDH or their summed influence on affecting HNM prognosis and follow-up care. METHODS: This retrospective cohort study analyzed 374,138 HNM in adults from 1975 to 2017 from the NCI-Surveillance, Epidemiology, and End Results Program (NCI-SEER) database. Utilizing the NCI-SEER database, Social Vulnerability Index (SVI) scores were matched to county of residence upon diagnosis. Univariate linear regressions were performed on length of care (months of follow-up/surveyed) and prognosis (months survival) across various SDH/SVI scores of socioeconomic status, minority and language status, household composition, housing and transportation, and their total composite. RESULTS: With increasing overall SVI score, which indicates increasing social vulnerability, months of follow-up showed significant decreases ranging from 0.04% to 27.63% compared with the lowest vulnerability groups, with the highest differences in nodular melanomas and the lowest with malignant melanomas in giant pigmented nevi. Similarly, months survival significant decreases ranged from 0.19% to 39.84% compared with the lowest SVI scores, with the highest difference in epithelioid cell melanomas and the lowest in amelanotic melanoma. Comprising this overall score trend, decreases with socioeconomic status, minority-language status, household composition, and housing-transportation contributed differentially per histology subtype. CONCLUSIONS: Our data highlight significant negative trends in HNM prognosis and care with higher total social vulnerability while showing which SDH-themes quantifiably contribute more to these differences.

RESUMO

OBJECTIVE: To compare head and neck squamous cell carcinoma stage at presentation and survival in Medicaid-expanded states versus nonexpanded states. STUDY DESIGN: Retrospective cohort. SETTING: Northwestern University Feinberg School of Medicine. METHODS: The Head and Neck with human papillomavirus Status Database within the Surveillance, Epidemiology, and End Results (SEER) Program was queried for cases of head and neck squamous cell carcinoma (HNSCC) diagnosed in the years 2010 to 2016. Cases were grouped according to their respective state Medicaid expansion status. Multivariable logistic regressions and multivariable Cox proportional hazards models were used to evaluate associations with stage IV disease and survival. RESULTS: Compared to nonexpanded states, Medicaid-expanded states had a significantly larger proportion of Medicaid patients (20.3% vs 16.7%, P = .0009) and a significantly smaller proportion of uninsured patients (1.7% vs 10.1%, P < .0001). The case selection process resulted in 2215 patients meeting inclusion criteria. In multivariable analysis, cases under Medicaid expansion were 31% less likely to present with stage IV disease compared to cases in nonexpanded states (odds ratio: 0.69, 95% confidence interval [CI]: 0.51-0.93). In the multivariable Cox proportional hazards model, cases under Medicaid expansion had significantly better mortality outcomes and were 32% less likely to die compared to cases in nonexpanded states (hazard ratio: 0.68, 95% CI: 0.55-0.84). CONCLUSION: Medicaid expansion is associated with fewer stage IV cases and improved survival of HNSCC cases. These findings support continued efforts to expand Medicaid coverage.

RESUMO

BACKGROUND: Prior studies in social determinants (SDoH) of truncal-extremity melanomas (TEM) have analyzed race, income, and environmental factors relative to their effect on health disparities. However, they are limited by the narrow scopes of SDoH and study population, while lacking analyses of interrelational contribution of SDoH on TEM disparities. METHODS: This retrospective cohort study of adult TEM patients (1975-2017) assessed linear regression trends in months of survival, as well as logistic regression trends in advanced presenting stage, surgery, and chemotherapy receipt across TEM subtypes with increasing overall social vulnerability and vulnerability in 15 SDoH variables grouped into socioeconomic status (SES), minority-language status (ML), household composition (HH), and housing-transportation (HT) themes measured by the SVI. SVI measures are ranked/compared across all US counties for relative vulnerability in a specific SDH and their total composite while accounting for sociodemographic-regional differences. RESULTS: Across 325 760 TEM patients, increasing overall social vulnerability demonstrated significant decreases in the survival period for 7/13 TEM histology types (p < 0.001), with relative decreases in the survival period as high as 44.0% (67.0-37.5 months) for epithelioid cell. SES and HH were the highest-magnitude contributors to these overall trends. For many patients with TEM, increased odds of advanced presenting stage (highest with acral-lentiginous: odds ratio [OR], -1.18; 95% confidence interval [CI], 1.02-1.36), decreased odds of indicated surgery receipt (lowest with amelanotic, 0.79; 0.71-0.87), and increased odds of indicated chemotherapy (highest with melanoma in giant nevi: 1.50; 1.01-2.44) were observed; SES and ML followed by HH and HT contributed to these trends. CONCLUSIONS: There were detriments in TEM care & prognosis in the United States with increasing social vulnerability. Identifying which SDH quantifiably are associated more with disparities in interrelational, real-world contexts is important to provide nuance to inform future research and initiatives to address TEM disparity.

RESUMO

OBJECTIVE To study the improvement effect of total flavonoids from Rosa multiflora root on vascular injury in rheumatoid arthritis (RA) model rats and its potential mechanism. METHODS Female Wistar rats were randomly divided into normal control group, model group, aspirin group (positive control, 30 mg/kg), low-dose and high-dose groups of total flavonoids from R. multiflora root (4.15, 8.30 g/kg, by crude drug), with 10 rats in each group. Except for the normal control group, the RA model was induced in other groups by collagen induction and high-fat diet. After 14 days of modeling, they were given corresponding drug solution/0.5% sodium carboxymethyl cellulose solution intragastrically, once a day, for 36 consecutive days. The total body score, arthritis index (AI) and swollen joint count (SJC) of the rats were evaluated regularly. After the last medication, serum levels of interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule- 1 (VCAM-1) were determined. The pathological morphological changes in the vascular tissue of thoracic aorta were observed; the protein expression of Toll-like receptor 4 (TLR4) and the protein phosphorylation levels of Janus kinase 2 (JAK2) and signal transduction and activator of transcription 3 (STAT3) in vascular tissue of thoracic aorta were measured. RESULTS Compared with the normal control group, serum levels of IL-6, ICAM-1 and VCAM-1, protein expression of TLR4, and the protein phosphorylation levels of JAK2 and STAT3 in vascular tissue of thoracic aorta were increased significantly in model group (P< 0.01). The atherosclerotic plaque (atheroma), cholesterol crystal, lymphocyte infiltration and a small number of unbroken foam cell aggregation could be seen in the vascular tissue of thoracic aorta. Compared with the model group, total body score (except for the low-dose group), AI and SJC were decreased significantly in groups of total flavonoids from R. multiflora root on the 28th day (P<0.05 or P<0.01); total body score,AI and SJC were decreased significantly in low-dose group of total flavonoids from R. multiflora root on the 49th day (P<0.05 or P<0.01); the other quantitative indicators in serum and vascular tissue were significantly reversed in groups of total flavonoids from R. multiflora root (P<0.05 or P<0.01), and pathological damage of vascular tissue was significantly relieved. CONCLUSIONS Total flavonoids from R. multiflora root can significantly improve vascular injury in RA model rats, and its mechanism may be related to reducing the protein expression of TLR4 in vascular tissue and inhibiting the activation of IL-6/JAK2/ STAT3 signaling pathway.

RESUMO

Aim To investigate the therapeutic effect of the MW-9 on ulcerative colitis(UC)and reveal the underlying mechanism, so as to provide a scientific guidance for the MW-9 treatment of UC. Methods The model of lipopolysaccharide(LPS)-stimulated RAW264.7 macrophage cells was established. The effect of MW-9 on RAW264.7 cells viability was detected by MTT assay. The levels of nitric oxide(NO)in RAW264.7 macrophages were measured by Griess assay. Cell supernatants and serum levels of inflammatory cytokines containing IL-6, TNF-α and IL-1β were determined by ELISA kits. Dextran sulfate sodium(DSS)-induced UC model in mice was established and body weight of mice in each group was measured. The histopathological damage degree of colonic tissue was assessed by HE staining. The protein expression of p-p38, p-ERK1/2 and p-JNK was detected by Western blot. Results MW-9 intervention significantly inhibited NO release in RAW264.7 macrophages with IC50 of 20.47 mg·L-1 and decreased the overproduction of inflammatory factors IL-6, IL-1β and TNF-α(P<0.05). MW-9 had no cytotoxicity at the concentrations below 6 mg·L-1. After MW-9 treatment, mouse body weight was gradually reduced, and the serum IL-6, IL-1β and TNF-α levels were significantly down-regulated. Compared with the model group, MW-9 significantly decreased the expression of p-p38 and p-ERK1/2 protein. Conclusions MW-9 has significant anti-inflammatory activities both in vitro and in vivo, and its underlying mechanism for the treatment of UC may be associated with the inhibition of MAPK signaling pathway.

RESUMO

OBJECTIVES: To develop and implement a novel, comprehensive tool, the Digital Inequity Index (DII), that quantifiably measures modern-technology access in the US to assess the impact of digital inequity on laryngeal cancer (LC) care nationwide. METHODS: DII was calculated based on 17 census-tract level variables derived from the American Community Survey and Federal Communications Commission. Variables were categorized as infrastructure-access (i.e., electronic device ownership, type of broadband, internet provider availability, income-broadband subscription ratio) or sociodemographic (i.e., education, income, disability status), ranked and then averaged into a composite score. 22,850 patients from 2008 to 2017 in SEER were assessed for regression trends in long-term follow-up, survival, prognosis, and treatment across increasing overall digital inequity, as measured by the DII. This methodology allows for us to assess the independent contribution of digital inequity adjusted for socioeconomic confounders. RESULTS: With increasing overall digital inequity, length of long-term follow-up (p < 0.001) and survival (p = 0.025) decreased. Compared to LC patients with low DII, high DII was associated with increased odds of advanced preliminary staging (OR 1.06; 95 % CI 1.03-1.08), treatment with chemotherapy (OR 1.06; 95 % CI 1.04-1.08), and radiation therapy (OR 1.02; 95 % CI 1.00-1.04), as well as decreased odds of surgical resection (OR 0.96; 95 % CI 0.94-97). CONCLUSIONS: Digital inequities are associated with detrimental trends in LC patient outcomes in the US, allowing discourse for targeted means of alleviating disparities while contextualizing national sociodemographic trends of the impact of online access on informed care.

RESUMO

BACKGROUND: There is currently no comprehensive tool that quantifiably measures validated factors of modern technology access in the US for digital inequity impact on esophageal cancer care (EC). OBJECTIVE: To assess the influence of digital inequities on esophageal cancer disparities while accounting for traditional social determinants. METHODS: 15,656 EC patients from 2013-2017 in SEER were assessed for significant regression trends in long-term follow-up, survival, prognosis, and treatment with increasing overall digital inequity, as measured by the Digital Inequity Index (DII). The DII was calculated based on 17 census tract-level variables derived from the American Community Survey and Federal Communications Commission. Variables were categorized as infrastructure access or sociodemographic, ranked, and then averaged into a composite score. RESULTS: With increasing overall digital inequity, significant decreases in the length of long-term follow-up (p < 0.001) and survival (p < 0.001) for EC patients were observed. EC patients showed decreased odds of receiving indicated surgical resection (OR 0.97, 95% CI 0.95-99) with increasing digital inequity. They also showed increased odds of advanced preliminary staging (OR 1.02, 95% CI 1.00-1.05) and decreased odds of receiving indicated chemotherapy (OR 0.97;95% CI 0.95-99). CONCLUSIONS: Digital inequities meaningfully contribute to detrimental trends in EC patient care in the US, allowing discourse for targeted means of alleviating disparities while contextualizing national, sociodemographic trends of the impact of online access on informed care.

RESUMO

PURPOSE OF REVIEW: Prior investigations in social determinants of health (SDoH) and their impact on pediatric head and neck cancers are limited by the narrow scope of cancer types and SDoH being studied while lacking inquiry on the interrelational contribution of varied SDoH in real-world contexts. The purpose of this review is to discuss the current research tackling these shortcomings of SDoH-based studies in head and neck cancer and to discuss means of applying these findings in prospective initiatives and implementations. RECENT FINDINGS: Through leveraging contemporary, large-data analyses measuring diverse social vulnerabilities, several studies have identified comprehensive delineations of which social disparities contribute the largest quantifiable impact on the care of head and neck cancer patients. Progressing from prior SDoH-based research of the decade, these studies contextualize the effect of social vulnerabilities and have laid the foundations to begin addressing these issues in the complex, modern-day environment of interrelatedsocial factors. SUMMARY: Social determinants of health markedly affect pediatric head and neck cancer care and prognosis in complex and surprising ways. Modern-day tools and analyses derived from large-data techniques have unveiled the quantifiable underpinnings of how SDoH impact these pathologies.

RESUMO

BACKGROUND: Modern-day internet access and technology usage substantially impacts aspects of surgical care but remain ill-defined for their associations with gastrointestinal-cancer (GIC) outcomes. We sought to develop the Digital Inequity Index (DII), a novel, a self-adapted tool to quantify access to digital resources, to assess the impact of "digital inequity" on GIC care and prognosis. METHODS: Adult (20+) patients with gastrointestinal malignancies between 2013 and 2017 were identified from the Surveillance, Epidemiology, and End Results Program database. DII was calculated based on 17 census-tract level variables derived from the American Community Survey and Federal Communications Commission. Variables were categorized as infrastructure-access (i.e., electronic device ownership, broadband type, internet provider availability, income-broadband subscription ratio) or sociodemographic (i.e., education, income, disability status), ranked relative across all US counties, and then averaged into a composite score. The association between DII and surgery receipt, staging, surveillance period, and survival time were assessed with multiple logistic and linear regressions. RESULTS: Among 287 228 patients, increasing DII was associated with increased odds of late-stage disease (highest odds ratio [OR]: 1.08, 95% confidence interval [CI]: 1.05-1.10 for hepatic) and decreased odds of receiving surgery (lowest OR: 0.94, 95% CI: 0.93-0.96 for hepatic). Higher DII was associated with shorter postoperative surveillance length (largest decrease -20.4% for hepatic) and overall survival length (largest decrease -16.0% for pancreatic). Sociodemographic and infrastructure-access factors contributed equivalently to surveillance time disparities, while infrastructure-access factors contributed more to survival disparities across GIC types. CONCLUSIONS: As technology dependence has increased, inequities in digital access should be targeted as a contributor to surgical oncologic disparities.

RESUMO

Objectives: To create an otolaryngology-specific needs assessment tool for short-term global surgical trips and to describe our findings from its implementation. Methods: Surveys 1 and 2 were developed based on a literature review and disseminated to Low-Middle Income (LMIC) hosting institutions in Kenya and Ethiopia and to High-Income surgical trip participants (HIC), respectively. Respondents were otolaryngologists identified online, through professional organizations, and by word-of-mouth, who had participated in a surgical trip of <4 weeks. Results: HIC and LMIC respondents shared similar goals of expanding host surgical skills through education and training while building sustainable partnerships. Discrepancies were identified between LMIC desired surgical skills and supply needs and HIC current practices. Microvascular reconstruction (17.6%), advanced otologic surgery (17.6%), and FESS (14.7%) were most desired skills and high-demand equipment needs were FESS sets (89%), endoscopes (78%), and surgical drills (56%). Frequently taught techniques included advanced otologic surgery (36.6%), congenital anomaly surgery (14.6%), and FESS (14.6%) with the largest gap between LMIC-need and HIC-offerings being in microvascular reconstruction (17.6% vs. 0%). We also highlight the discrepancy in expectations of responsibility for trip logistics, research, and patient follow-up. Conclusion: We created and implemented the first otolaryngology-specific needs assessment tool in the literature. With its implementation in Ethiopia and Kenya, we were able to identify unmet needs as well as attitudes and perceptions of LMIC and HIC participants. This tool may be adapted and utilized to assess specific needs, resources, and goals of both host and visiting teams to facilitate successful global partnerships. Level of Evidence: Level VI.
