Material, Psychological, and Behavioral Financial Hardship Among Lesbian, Gay, and Bisexual Cancer Survivors in the United States.
PURPOSE: Driven by anti-LGBTQ+ stigma, emerging literature suggests that lesbian, gay, and bisexual (LGB) cancer survivors experience financial hardship (FH) more frequently than heterosexual survivors. However, few studies have used nationally representative samples to estimate this inequity.
METHODS: National Health Interview Survey data from 2019 to 2022 were pooled and weighted. Outcomes included material, psychological, and behavioral FH. The behavioral domain was further broken down into subdomains including medical care, prescription medications, and mental health care. Multivariable logit models controlling for a variety of factors were used to generate LGB and heterosexual predicted probabilities and differential effects for each FH outcome. Stratified estimates were generated by sex and age groups.
RESULTS: A total of N = 374 LGB and N = 12,757 heterosexual cancer survivors were included in this analysis. In adjusted analyses, LGB cancer survivors had significantly higher material (19%, 95% CI, 15 to 24 v 12%, 95% CI, 11 to 13; P = .004), psychological (44%, 95% CI, 38 to 51 v 37%, 95% CI, 36 to 38; P = .035), and behavioral (23%, 95% CI, 18 to 28 v 13%, 95% CI, 13 to 14; P < .0001) FH than heterosexual survivors. LGB cancer survivors also had higher medical behavioral (11%, 95% CI, 7 to 15 v 7%, 95% CI, 6 to 7; P = .030), prescription medication behavioral (14%, 95% CI, 10 to 19 v 10%, 95% CI, 9 to 10; P = .032), and mental health behavioral (9%, 95% CI, 6 to 13 v 3%, 95% CI, 3 to 4; P < .0001) FH than heterosexual survivors. Stratified estimates revealed young LGB cancer survivors had the highest probability of each outcome (material: 31%, 95% CI, 23 to 40; psychological: 58%, 95% CI, 50 to 66; behavioral: 45%, 95% CI, 36 to 53).
CONCLUSION: In this nationally representative analysis, LGB cancer survivors experience substantial inequities in all FH outcomes. It is crucial that future FH interventional work should prioritize populations at the highest risk of FH, such as LGB cancer survivors
Determinants of cord blood adipokines and association with neonatal abdominal adipose tissue distribution
Background Cord blood leptin and adiponectin are adipokines known to be associated with birth weight and overall infant adiposity. However, few studies have investigated their associations with abdominal adiposity in neonates. We examined maternal factors associated with cord blood leptin and adiponectin, and the association of these adipokines with neonatal adiposity and abdominal fat distribution measured by magnetic resonance imaging (MRI) in an Asian mother-offspring cohort. Methods Growing Up in Singapore Towards healthy Outcomes (GUSTO), is a prospective mother-offspring birth cohort study in Singapore. Cord blood plasma leptin and adiponectin concentrations were measured using Luminex and Enzyme-Linked Immunosorbent Assay respectively in 816 infants. A total of 271 neonates underwent MRI within the first 2-weeks after delivery. Abdominal superficial (sSAT), deep subcutaneous (dSAT), and intra-abdominal (IAT) adipose tissue compartment volumes were quantified from MRI images. Multivariable regression analyses were performed. Results Indian or Malay ethnicity, female sex, and gestational age were positively associated with cord blood leptin and adiponectin concentrations. Maternal gestational diabetes (GDM) positively associated with cord blood leptin concentrations but inversely associated with cord blood adiponectin concentrations. Maternal pre-pregnancy body mass index (BMI) showed a positive relationship with cord blood leptin but not with adiponectin concentrations. Each SD increase in cord blood leptin was associated with higher neonatal sSAT, dSAT and IAT; differences in SD (95% CI): 0.258 (0.142, 0.374), 0.386 (0.254, 0.517) and 0.250 (0.118, 0.383), respectively. Similarly, each SD increase in cord blood adiponectin was associated with higher neonatal sSAT and dSAT; differences in SD (95% CI): 0.185 (0.096, 0.274) and 0.173 (0.067, 0.278), respectively. The association between cord blood adiponectin and neonatal adiposity was observed in neonates of obese mothers only. Conclusions Cord blood leptin and adiponectin concentrations were associated with ethnicity, maternal BMI and GDM, sex and gestational age. Both adipokines showed positive association with neonatal abdominal adiposity.Peer reviewe
The Kynurenine Pathway Metabolites in Cord Blood Positively Correlate With Early Childhood Adiposity
Context The kynurenine pathway generates metabolites integral to energy metabolism, neurotransmission, and immune function. Circulating kynurenine metabolites positively correlate with adiposity in children and adults, yet it is not known whether this relationship is present already at birth. Objective In this prospective longitudinal study, we investigate the relationship between cord blood kynurenine metabolites and measures of adiposity from birth to 4.5 years. Methods Liquid chromatography-tandem mass spectrometry was used to quantify cord blood kynurenine metabolites in 812 neonates from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study. Fat percentage was measured by air displacement plethysmography and abdominal adipose tissue compartment volumes; superficial (sSAT) and deep subcutaneous (dSAT) and internal adipose tissue were quantified by magnetic resonance imaging at early infancy in a smaller subset of neonates, and again at 4 to 4.5 years of age. Results Cord blood kynurenine metabolites appeared to be higher in female newborns, higher in Indian newborns compared with Chinese newborns, and higher in infants born by cesarean section compared with vaginal delivery. Kynurenine, xanthurenic acid, and quinolinic acid were positively associated with birthweight, but not with subsequent weight during infancy and childhood. Quinolinic acid was positively associated with sSAT at birth. Kynurenic acid and quinolinic acid were positively associated with fat percentage at 4 years. Conclusion Several cord blood kynurenine metabolite concentrations were positively associated with birthweight, with higher kynurenic acid and quinolinic acid correlating to higher percentage body fat in childhood, suggesting these cord blood metabolites as biomarkers of early childhood adiposity.Peer reviewe
“How am I Going to Live? How am I Going to Pay Rent?”: A Mixed Methods Investigation of Employment, Stigma, and Financial Hardship Among LGBTQ+ Cancer Caregivers
Plain Language Summary
LGBTQ+ cancer caregivers face financial hardship associated with job changes and stigma. Why was the study done? Caring for a loved one with cancer can be expensive, and many caregivers have to change or leave their jobs, leading to financial strain. LGBTQ+ individuals are more likely to face financial challenges and workplace discrimination, which may make caregiving even harder. This study aimed to understand how employment changes and LGBTQ+ stigma was associated the financial well-being of LGBTQ+ cancer caregivers. What did the researchers do? The researchers conducted a national survey of 332 LGBTQ+ cancer caregivers and interviewed 14 of them to learn more about their experiences. They analyzed the survey data to identify factors linked to financial hardship and examined the interviews to understand the challenges caregivers face. What did the researchers find? Many LGBTQ+ caregivers experienced significant financial hardship. Caregivers who had to change/quit jobs had more than three times the odds of financial difficulties. Those who experienced anti-LGBTQ+ stigma were also more likely to struggle financially. The interviews revealed three major themes that revolved around financial burden, LGBTQ+ identity and varying levels of support, as well as unmet financial needs. What do the findings mean? LGBTQ + cancer caregivers face serious financial challenges, especially when they have to change jobs or encounter stigma. Support programs should consider the unique needs of LGBTQ+ caregivers and work to reduce financial hardship and stigma.Introduction Employment changes among cancer caregivers are common and can result in financial hardship. Lesbian, gay, bisexual, transgender, queer, and other identities outside of cisgender heterosexual (LGBTQ+) individuals are more likely to live in poverty and experience workplace discrimination than non-LGBTQ+ individuals. This study aimed to assess the impact of caregiving-related employment changes and anti-LGBTQ+ stigma on financial hardship and describe lived experiences with financial hardship and related employment changes among LGBTQ+ cancer caregivers. Methods An explanatory mixed-methods study was conducted and included a national survey and individual interviews with survey participants. Multivariable logistic regression models were used to test the association of employment changes with financial hardship. An inductive qualitative analysis guided by two of the three domains of financial hardship (ie, material and behavioral) was conducted. Quantitative and qualitative data were integrated throughout the study. Results A total of N = 332 LGBTQ+ cancer caregivers participated in the survey, and N = 14 participated in an interview. The average modified COmprehensive Score for financial Toxicity and Caregiver Reaction Assessment financial sub-scale were 25.6 (SD: 9.9, Range: 1-44) and 2.99 (SD: 1.0, Range: 1-5). Employment changes (OR: 3.32, 95% CI: 1.73-6.36) and anti-LGBTQ+ stigma (OR: 2.21, 95% CI: 1.47-3.32) were associated with high financial hardship. Three overarching themes from the qualitative analysis included: 1) Financial Hardship: Increased Costs, Strained Finances, and Lost Wages; 2) Caregiving as an LGBTQ+ Person: Stigma, Outness, and Expectations; and 3) Financial Unmet needs and Recommendations. Conclusion LGBTQ+ cancer caregivers experience substantial financial hardship that is associated with employment changes and anti-LGBTQ+ stigma. LGBTQ + cancer caregivers reported varying levels of outness and acceptance that directly influenced their access to financial support. Cancer-related financial hardship interventions tailored to the needs of LGBTQ+ individuals are needed
The socioeconomic landscape of the exposome during pregnancy
Background: While socioeconomic position (SEP) is consistently related to pregnancy and birth outcome dis-parities, relevant biological mechanisms are manifold, thus necessitating more comprehensive characterization of SEP-exposome associations during pregnancy. Objectives: We implemented an exposomic approach to systematically characterize the socioeconomic landscape of prenatal exposures in a setting where social segregation was less distinct in a hypotheses-generating manner. Methods: We described the correlation structure of 134 prenatal exogenous and endogenous sources (e.g., micronutrients, hormones, immunomodulatory metabolites, environmental pollutants) collected in a diverse, population-representative, urban, high-income longitudinal mother-offspring cohort (N = 1341; 2009-2011). We examined the associations between maternal, paternal, household, and areal level SEP indicators and 134 ex-posures using multiple regressions adjusted for precision variables, as well as potential effect measure modifi-cation by ethnicity and nativity. Finally, we generated summary SEP indices using Multiple Correspondence Analysis to further explore possible curved relationships. Results: Individual and household SEP were associated with anthropometric/adiposity measures, folate, omega-3 fatty acids, insulin-like growth factor-II, fasting glucose, and neopterin, an inflammatory marker. We observed paternal education was more strongly and consistently related to maternal exposures than maternal education. This was most apparent amongst couples discordant on education. Analyses revealed additional non-linear as-sociations between areal composite SEP and particulate matter. Environmental contaminants (e.g., per-and polyfluoroalkyl substances) and micronutrients (e.g., folate and copper) showed opposing associations by ethnicity and nativity, respectively. Discussion: SEP-exposome relationships are complex, non-linear, and context specific. Our findings reinforce the potential role of paternal contributions and context-specific modifiers of associations, such as between ethnicity and maternal diet-related exposures. Despite weak presumed areal clustering of individual exposures in our context, our approach reinforces subtle non-linearities in areal-level exposures.Peer reviewe
Associations of childcare arrangements with adiposity measures in a multi-ethnic Asian cohort : The gusto study
Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland.Childcare arrangements shape behavioural patterns that influence the risk of childhood obesity. However, little is known of its influence on childhood obesity in Singapore. We aim to examine the associations between childcare arrangements at the age of 5 years and childhood adiposity at age 6 years. Children from the GUSTO study were grouped into three childcare arrangements at age 5: Full-time centre-based childcare (FC), partial centre-based with parental care (PCP), and partial centre-based with non-parents (grandparents and domestic helpers) as caregivers (PCN). Diet, physical activity and sedentary behaviour information were collected at age 5, while anthropometric measurements were collected at age 6. Associations were analysed using multivariable regression models. Among 540 children, those in PCN had higher BMI z-scores (β: 0.34; 95% CI: 0.01, 0.66), greater sum of skinfold thicknesses (mm) (β: 3.75; 95% CI: 0.53, 6.97) and were 3.55 times (95% CI: 1.78, 7.05) more likely to be overweight/obese than those in FC. Adiposity measures in PCP children did not differ from those in FC. PCN children were reported to have more screen time and greater fast-food intake. Children in PCN tended to have higher adiposity measures. Greater engagement of non-parental caregivers should be considered in interventions targeting child obesity.Peer reviewe
The effect of pyramiding Phytophthora infestans resistance genes RPi-mcd1 and RPi-ber in potato
Despite efforts to control late blight in potatoes by introducing Rpi-genes from wild species into cultivated potato, there are still concerns regarding the durability and level of resistance. Pyramiding Rpi-genes can be a solution to increase both durability and level of resistance. In this study, two resistance genes, RPi-mcd1 and RPi-ber, introgressed from the wild tuber-bearing potato species Solanum microdontum and S. berthaultii were combined in a diploid S. tuberosum population. Individual genotypes from this population were classified after four groups, carrying no Rpi-gene, with only RPi-mcd1, with only RPi-ber, and a group with the pyramided RPi-mcd1 and RPi-ber by means of tightly linked molecular markers. The levels of resistance between the groups were compared in a field experiment in 2007. The group with RPi-mcd1 showed a significant delay to reach 50% infection of the leaf area of 3 days. The group with RPi-ber showed a delay of 3 weeks. The resistance level in the pyramid group suggested an additive effect of RPi-mcd1 with RPi-ber. This suggests that potato breeding can benefit from combining individual Rpi-genes, irrespective of the weak effect of RPi-mcd1 or the strong effect of RPi-ber
Broad spectrum late blight resistance in potato differential set plants MaR8 and MaR9 is conferred by multiple stacked R genes
Phytophthora infestans is the causal agent of late blight in potato. The Mexican species Solanum demissum is well known as a good resistance source. Among the 11 R gene differentials, which were introgressed from S. demissum, especially R8 and R9 differentials showed broad spectrum resistance both under laboratory and under field conditions. In order to gather more information about the resistance of the R8 and R9 differentials, F1 and BC1 populations were made by crossing Mastenbroek (Ma) R8 and R9 clones to susceptible plants. Parents and offspring plants were examined for their pathogen recognition specificities using agroinfiltration with known Avr genes, detached leaf assays (DLA) with selected isolates, and gene-specific markers. An important observation was the discrepancy between DLA and field trial results for Pi isolate IPO-C in all F1 and BC1 populations, so therefore also field trial results were included in our characterization. It was shown that in MaR8 and MaR9, respectively, at least four (R3a, R3b, R4, and R8) and seven (R1, Rpi-abpt1, R3a, R3b, R4, R8, R9) R genes were present. Analysis of MaR8 and MaR9 offspring plants, that contained different combinations of multiple resistance genes, showed that R gene stacking contributed to the Pi recognition spectrum. Also, using a Pi virulence monitoring system in the field, it was shown that stacking of multiple R genes strongly delayed the onset of late blight symptoms. The contribution of R8 to this delay was remarkable since a plant that contained only the R8 resistance gene still conferred a delay similar to plants with multiple resistance genes, like, e.g., cv Sarpo Mira. Using this “de-stacking” approach, many R gene combinations can be made and tested in order to select broad spectrum R gene stacks that potentially provide enhanced durability for future application in new late blight resistant varieties
