Association Between Healthy Eating Index-2020 and Oral Microbiome Among Postmenopausal Women.

BACKGROUND: Dietary intake has been suggested to be associated with the oral microbiome, but no study has examined the association between overall diet quality and the oral microbiome. OBJECTIVES: This study aimed to investigate the cross-sectional association between the Healthy Eating Index-2020 (HEI-2020) and the diversity and composition of the oral microbiome among participants in the Buffalo Osteoporosis and Periodontal Disease (OsteoPerio) Study. METHODS: In 1175 postmenopausal women (mean age: 67 ± 7.0 y), we estimated the HEI-2020 scores for each woman from a food frequency questionnaire administered from 1997 to 2000. Bacterial DNA was extracted from subgingival plaque samples and analyzed using 16S ribosomal RNA sequencing. The alpha-diversity (within-sample diversity) and ß-diversity (between-sample diversity) across HEI-2020 quartiles were examined using analysis of covariance and permutational multivariate analysis of variance, respectively. The associations between the HEI-2020 score and the relative abundance of microbial taxa were examined by linear regression models. The analyses were further conducted for individual components of the HEI-2020. RESULTS: No statistically significant associations were observed between the HEI-2020 scores and alpha- or beta-diversity. However, greater consumption of seafood, plant proteins, and total protein and lower consumption of added sugars were positively associated with alpha-diversity. After we applied a false detection rate (FDR) correction, higher HEI-2020 scores were significantly associated with decreased abundance of Lautropia, Streptococcus gordonii, Cardiobacterium valvarum, and Cardiobacterium hominis, and increased abundance of Selenomonas sp. oral taxon 133 and Selenomonas dianae (FDR-adjusted P values < 0.10). Additionally, 28 other taxa were identified as being associated with HEI-2020 components. CONCLUSIONS: Although the HEI-2020 was associated with the composition, but not the diversity, of the oral microbiome, individual HEI-2020 components were associated with both its diversity and composition. Specific dietary components may have more impact on the diversity and composition of oral microbiome than overall diet quality assessed by the HEI-2020.

Diet quality and blood lead levels in Uruguayan first graders.

OBJECTIVE: Foods are a potential source of lead but also contain nutrients that counteract the intestinal absorption of lead. Translatable evidence is needed to better understand the relationship between whole diets and blood lead levels (BLLs) in children. In this cross-sectional study we investigated the association between dietary variety, adequacy, moderation, and overall diet quality with children's BLLs. METHODS: First graders (~ 7 years) from Montevideo, Uruguay were evaluated in years 2009-13 (Phase I, n = 303) and 2015-19 (Phase II, n = 443). Lead was measured in fasting blood via atomic absorption spectrometry and primary caregivers completed two non-consecutive 24-h recalls. Indices of dietary variety (maximum score of 20), adequacy (maximum 40), moderation (maximum 30), and overall diet quality were calculated from food and nutrient intakes averaged over two recall days. The indices were adapted from the Diet Quality Index-International based on dietary recommendations for children. Missing covariate data were imputed. The associations between diet quality measures and BLLs were modeled separately in Phase I and II with multivariable linear models, testing for sex differences via interaction terms and stratified models. RESULTS: The median[IQR] BLLs were 3.8[2.6, 4.9] and 1.3[0.7, 3.6] µg/dL in study Phases I and II, respectively. All diet quality scores were <60 % of the maximum values and daily intakes of key food groups fell below recommended levels. There was little evidence of an association between measures of diet quality and children's BLLs overall. On the other hand, higher diet variety, adequacy, and overall diet quality were associated with slightly higher BLLs among girls in Phase I only. CONCLUSIONS: In the context of low lead exposure and food consumption patterns that fall short of recommended levels, the relation of diet quality to children's BLLs may depend on lead exposure levels.

Accuracy of self-reported treated hypertension in the women's health initiative: Comparisons with medication inventories.

Few studies have reported on the accuracy of self-reported hypertension history among older postmenopausal women, which was this study's objective. Participants were postmenopausal women enrolled in the Osteoporosis and Periodontal Disease (OsteoPerio) study, an ancillary investigation of the Women's Health Initiative Observational Study (WHI-OS) at the Buffalo, New York, clinical site. Participants self-reported their history of physician diagnosed hypertension treated with medication at WHI-OS enrollment (1993-1998; n = 1342, mean age 63 years), then 3 years later at OsteoPerio enrollment (1997-2001; n = 1342), and again at OsteoPerio Year 5 follow-up (2002-2005; n = 1020). At each time point, medication inventories were recorded and served as the criterion with which self-report was compared in the present study. Physician diagnosed-treated hypertension was also self-reported annually on mailed health update questionnaires in the WHI-OS and were compared against medication inventory at the subsequent clinic exam. Of those participants who self-reported a history of hypertension at WHI enrollment, OsteoPerio enrollment, and OsteoPerio Year 5 follow-up, 41.2%, 90.3%, and 94.4%, respectively, had anti-hypertensive pills in their medication inventory. Across the three time points, sensitivity and specificity ranged from 0.72 to 0.98 and from 0.85 to 0.95, and kappa coefficients ranged from 0.52 to 0.79 when comparing self-report with medication inventory. For self-reported newly physician-diagnosed and treated hypertension on the annual health update questionnaire, 88.4% and 95.2% of those reporting hypertension had anti-hypertensive pills in the subsequent medication inventory. In general, sensitivity and kappa were lower in women aged ≥70 versus < 70 years and in those with history of cardiovascular disease and diabetes compared to those without these comorbidities. In this cohort of postmenopausal women, self-reported physician diagnosed and treated hypertension demonstrated moderate to high accuracy when compared against anti-hypertensive medication use documented by pill inventory, particularly for those who were younger and managing fewer comorbidities.

Sex and race disparities in the association between work characteristics and vitamin D deficiency: findings from the National Health and Nutrition Examination Survey, 2005-2010.

OBJECTIVES: Vitamin D deficiency is highly prevalent worldwide; however, few large population-based studies have examined occupational risk factors. We examined associations between shift work, work schedule, hours worked, outdoor work, occupation and serum 25-hydroxyvitamin D (25(OH)D) levels in the US working population. METHODS: This cross-sectional study included 8601 workers from the 2005-2010 National Health and Nutrition Examination Survey (NHANES) cycles. NHANES occupational data were supplemented with measures of outdoor work from the Occupational Information Network. Serum 25(OH)D concentration in nanomoles per litre (nmol/L) was categorised as sufficient (≥75), insufficient (50-<75), moderately deficient (30-<50) and severely deficient (<30). Age-adjusted weighted multinomial and binary logistic regression were used to examine associations between work-related factors and vitamin D status with sex-race/ethnicity stratification. RESULTS: Shift workers had higher odds of severe vitamin D deficiency compared with day workers (OR: 1.64, 95% CI 1.22 to 2.19). Compared with those in white-collar occupations, those in natural resources were less likely to be deficient (OR: 0.31, 95% CI 0.19 to 0.52), while those in production were more likely to be deficient (OR: 2.25, 95% CI 1.48 to 3.43). Women working ≥40 hours/week compared with <40 hours/week were more likely to be moderately deficient (OR: 1.30, 95% CI 1.06 to 1.59). Black women working in sales were more likely to be deficient than those in management (OR: 1.53, 95% CI 1.03 to 2.27). Mexican American men working nights had the highest odds of deficiency (OR: 2.64, 95% CI 1.38 to 5.06). CONCLUSIONS: Work-related factors were associated with vitamin D status and there were race/ethnicity and sex differences. Targeted vitamin D screening and supplementation interventions may reduce these disparities.

Developing and evaluating the construct validity of a dietary pattern predictive of plasma TMAO and choline.

BACKGROUND AND AIMS: The metabolism of choline (highly present in animal products) can produce trimethylamine N-oxide (TMAO), a metabolite with atherosclerotic effects; however, dietary fiber may suppress this metabolic pathway. This study aimed to develop a dietary pattern predictive of plasma TMAO and choline concentrations using reduced rank regression (RRR) and to evaluate its construct validity. METHODS AND RESULTS: Diet and plasma concentrations of choline (µmol/L) and TMAO (µmol/L) were assessed in 1724 post-menopausal women who participated in an ancillary study within the Women's Health Initiative Observational Study (1993-1998). The TMAO dietary pattern was developed using RRR in half of the sample (Training Sample) and applied to the other half of the sample (Validation Sample) to evaluate its construct validity. Energy-adjusted food groups were the predictor variables and plasma choline and TMAO, the response variables. ANCOVA and linear regression models were used to assess associations between each biomarker and the dietary pattern score. Discretionary fat, potatoes, red meat, and eggs were positively associated with the dietary pattern, while yogurt, fruits, added sugar, and starchy vegetables were inversely associated. Mean TMAO and choline concentrations significantly increased across increasing quartiles of the dietary pattern in the Training and Validation samples. Positive associations between the biomarkers and the TMAO dietary pattern were also observed in linear regression models (Validation Sample: TMAO, adjusted beta-coefficient = 0.037 (p-value = 0.0088); Choline, adjusted beta-coefficient = 0.011 (p-value = 0.0224). CONCLUSION: We established the TMAO dietary pattern, a dietary pattern reflecting the potential of the diet to contribute to plasma concentrations of TMAO and choline.

Bean Consumption during Childhood Is Associated with Improved Nutritional Outcomes in the First Two Years of Life.

Bean consumption during childhood may play a role in promoting early-life health given their high nutritional quality. To examine the associations of children's bean consumption with the socio-demographic characteristics of the child and mother and the child's nutrient intake, we analyzed data from the WIC-ITFPS-2, which followed children and their mothers at 1, 3, 5, 7, 9, 11, 13, 15, 18, and 24 months (m) following birth. Caregivers (mostly mothers) responded to an interview-administered 24 h recall on their child's dietary intake at each time point. The intake of dried beans, chili, yellow beans, and lima beans was quantified. Correlate measures included socio-demographic characteristics. Outcome measures of interest focused on the intake of macronutrients (grams and % kcals) and micronutrients at 11 (infancy) and 24 m (toddler) only. To ensure statistical power, we only examined the associations of dried beans and chili with socio-demographics (Chi-square tests) and nutritional outcomes (ANOVA) at 11 and 24 m. The proportion of children who consumed dried beans or chili was very low in the first 6 m of age, started to increase at 7 m (1.2% and 0.4%) and 11 m (4.9% and 2.3%), and reached a high level at 18 m (10.5%) and 24 m (5.9%), respectively. Consumption of yellow or lima beans was rare (<0.1%). At 11 and 24 m, dried bean consumption was higher in children who were White (vs. Black). Dried bean and chili consumption was higher in children who were of Hispanic or Latino ethnicity (vs. non-Hispanic or non-Latino ethnicity). Children who consumed dried beans and chili at 11 or 24 m had a higher intake of total energy, protein, total fiber, potassium, folate, and magnesium compared with non-consumers. The bean consumption was low amongst children, differed by race and ethnicity, and was associated with improved macro- and micronutrient intake in children at 11 and 24 m.

Association between dietary patterns and periodontal disease: The OsteoPerio cohort study.

AIM: To examine the association of dietary patterns with periodontal disease (PD) and its progression over 5 years. MATERIALS AND METHODS: Analyses involved 1197 post-menopausal women from the OsteoPerio cohort. Dietary patterns assessed include Healthy Eating Index-2015 (HEI), Alternative HEI (AHEI), Dietary Approaches to Stop Hypertension (DASH) and alternate Mediterranean Diet (aMed) at baseline (the average of two food frequency questionnaires administered between 1993 and 2001). At baseline and the 5-year follow-up, periodontal assessments evaluated alveolar crestal height (ACH), probing pocket depth (PPD), clinical attachment loss (CAL), percentage of gingival sites bleeding on probing (%BOP) and missing teeth due to PD. Linear and logistic regression were used to examine the associations. RESULTS: Cross-sectionally, HEI and aMed were associated with smaller CAL and %BOP; along with DASH, they were associated with a decreased odds of teeth missing due to PD. AHEI and aMed were associated with a decreased odds of severe PD. Prospectively, AHEI was associated with greater ACH progression. This association was attenuated to the null after loss of ACH was imputed for teeth lost due to PD over follow-up, or after excluding participants with diabetes, osteoporosis, hypertension or heart disease at baseline. CONCLUSIONS: Better adherence to healthy dietary patterns was associated with better PD measures cross-sectionally but greater progression of ACH over 5 years. The latter might be explained by incident tooth loss due to PD and pre-existing comorbidities.

Alcohol Consumption and the Diversity of the Oral Microbiome in Postmenopausal Women.

BACKGROUND: Alcohol reduces neutrophil function and decreases salivary flow, which could affect the composition of the oral microbiome. OBJECTIVE: We hypothesized that the α- and ß-diversity of the oral microbiome and the relative abundance of bacterial taxa would differ by frequency and type of alcohol consumption. METHODS: We used a food frequency questionnaire to assess the frequency of consumption of beer, wine, and liquor (drinks/week) in a sample of 1179 postmenopausal women in the Osteoporosis and Periodontal Disease Study. Women were categorized as nondrinkers, drinking <1 drink/wk, ≥1 to <7 drinks/wk, or ≥7 drinks/wk for total alcohol consumption and for beer, wine, and liquor consumption. The composition and diversity of the oral microbiome was assessed from subgingival plaque samples using 16S ribosomal RNA amplicon sequencing. Permutational multivariate analysis of variance (PERMANOVA) was used to examine ß-diversity (between-sample diversity) in the microbiome between alcohol consumption categories. Analysis of covariance was used to examine the mean α-diversity (within-sample diversity), assessed by the Shannon index (species evenness), Chao1 index (species richness), and observed operational taxonomic unit (OTU) count and the mean relative abundance of 245 bacterial taxa across alcohol consumption categories. RESULTS: Over half of the participants (67%) consumed alcohol, with 14% reporting ≥1 drink/d. The ß-diversity across categories of total alcohol consumption, but not categories of alcohol type, was statistically significantly different (P for PERMANOVA = 0.016). Mean α-diversity measures were statistically significantly higher (P < 0.05) in the highest category of total alcohol and wine consumption compared to nondrinkers; no significant associations were found for beer or liquor consumption. The relative abundance of 1 OTU, Selenomonassp._oral_taxon_133, was significantly lower in the highest level of total alcohol consumption compared to nondrinkers after adjustment for multiple comparisons. CONCLUSIONS: Alcohol consumption was associated with the diversity and composition of the subgingival microbiome.

Air Pollution and Chronic Eye Disease in Adults: A Scoping Review.

PURPOSE: We conducted a scoping review of studies examining ambient air pollution as a risk factor for chronic eye disease influencing the lens, retina, and intraocular pressure in adults. METHODS: Terms related to air pollution and eye disease outcomes were used to search for publications on Embase, Web of Science Core Collection, Global Health, PubMed, and the Cochrane Central Register of Controlled Trials from January 1, 2010, through April 11, 2022. RESULTS: We identified 27 articles, focusing on the following non-mutually exclusive outcomes: cataract (n = 9), presbyopia (n = 1), retinal vein occlusion or central retinal arteriolar and venular equivalents (n = 5), intraocular pressure (IOP) (n = 3), glaucoma (n = 5), age-related macular degeneration (AMD) (n = 5), diabetic retinopathy (n = 2), and measures of retinal morphology (n = 3). Study designs included cross-sectional (n = 16), case-control (n = 4), and longitudinal (n = 7). Air pollutants were measured in 50% and 95% of the studies on lens and retina or IOP, respectively, and these exposures were assigned to geographic locations. Most research was conducted in global regions with high exposure to air pollution. Consistent associations suggested a possibly increased risk of cataract and retina-associated chronic eye disease with increasing exposure to particulate matter (PM2.5-PM10), NO2, NOx, and SO2. Associations with O3 were less consistent. CONCLUSIONS: Accumulating research suggests air pollution may be a modifiable risk factor for chronic eye diseases of the lens and retina. The number of studies on each specific lens- or retina-related outcome is limited. Guidelines regarding the role of air pollution in chronic eye disease do not exist.

Retrospective analysis of vertical Hepatitis C exposure and infection in children in Western New York.

BACKGROUND: Vertical transmission of hepatitis C virus (HCV) is the primary cause of hepatitis C in the pediatric population. Nonetheless, only a small proportion of HCV-exposed children are tested. This study aimed to measure the proportion of HCV-exposed children tested and infected in Western New York and to identify factors influencing the odds of testing and infection in this population. METHODS: This was a 11-year retrospective chart review study in which clinical, demographic, and behavioral data for HCV-exposed children and their mothers were collected. This period included year 2019 when a hepatitis C program began promoting early hepatitis C screening among infants born to mothers positive for hepatitis C. PCR-based detection of hepatitis C was used for children under 18 months of age and antibody testing for children above 18 months of age, followed by PCR if the antibody testing was positive. Logistic regression models were used to determine which characteristics associate with testing and infection status. RESULTS: From a total of 133 children evaluated in clinic for hepatitis C from 2011 to 2021, 96.2% (128/133) were seen from 2019 to 2021. Among the 133 HCV-exposed children in our sample, 72.1% (96/133) were tested for HCV, 62.4% (83/133) were tested by PCR, 9.0% (12/133) tested by antibody, and 5.2% (5/95) of those tested were infected. Only one child out of 12 was positive for hepatitis C antibody yet, subsequent PCR testing was negative in this child. Among all five hepatitis C infected children, four were diagnosed with neonatal abstinence syndrome, five had maternal history of illicit drug use, one had maternal history of HIV infection, and all of them were identified after the hepatitis C program open in 2019. The odds of a child being tested were lower for those accompanied by their biological mother at their clinic visit (odds ratio, 0.16; 95% CI, 0.06-0.45). CONCLUSIONS: Screening programs on hepatitis C vertical transmission improved detection of hepatitis C among exposed children. The proportion of children born to mothers with hepatitis C in Western New York that were positive for hepatitis C was 5.2%, suggesting that similar proportion of exposed infants born before 2019 were lost for follow up.

Dietary Fats and All-cause and Breast Cancer-specific Mortality among Women with Breast Cancer: The Western New York Exposures and Breast Cancer Study.

BACKGROUND: Study results of prediagnostic dietary fat intake and breast cancer mortality have been inconclusive. While dietary fat subtypes [saturated (SFA), polyunsaturated (PUFA), and monounsaturated (MUFA) fatty acids] may have different biological effects, there is little evidence regarding the association of dietary fat and fat subtype intake with mortality after breast cancer diagnosis. METHODS: Women with incident, pathologically confirmed invasive breast cancer and complete dietary data (n = 793) were followed in a population-based study, the Western New York Exposures and Breast Cancer study. Usual intake before diagnosis of total fat and subtypes were estimated from a food frequency questionnaire completed at baseline. HRs and 95% confidence intervals (CI) for all-cause and breast cancer-specific mortality were estimated with Cox proportional hazards models. Interactions by menopausal status, estrogen receptor (ER) status, and tumor stage were examined. RESULTS: Median follow-up time was 18.75 years; 327 (41.2%) participants had died. Compared with lower intake, greater intake of total fat (HR, 1.05; 95% CI, 0.65-1.70), SFA (1.31; 0.82-2.10), MUFA (0.99; 0.61-1.60), and PUFA (0.99; 0.56-1.75) was not associated with breast cancer-specific mortality. There was also no association with all-cause mortality. Results did not vary by menopausal status, ER status, or tumor stage. CONCLUSIONS: Prediagnostic intake of dietary fat and fat subtypes was not associated with either all-cause or breast cancer mortality in a population-based cohort of breast cancer survivors. IMPACT: Understanding factors affecting survival among women diagnosed with breast cancer is critically important. Dietary fat intake prior to diagnosis may not impact that survival.

Circulating vitamin D and breast cancer risk: an international pooling project of 17 cohorts.

Laboratory and animal research support a protective role for vitamin D in breast carcinogenesis, but epidemiologic studies have been inconclusive. To examine comprehensively the relationship of circulating 25-hydroxyvitamin D [25(OH)D] to subsequent breast cancer incidence, we harmonized and pooled participant-level data from 10 U.S. and 7 European prospective cohorts. Included were 10,484 invasive breast cancer cases and 12,953 matched controls. Median age (interdecile range) was 57 (42-68) years at blood collection and 63 (49-75) years at breast cancer diagnosis. Prediagnostic circulating 25(OH)D was either newly measured using a widely accepted immunoassay and laboratory or, if previously measured by the cohort, calibrated to this assay to permit using a common metric. Study-specific relative risks (RRs) for season-standardized 25(OH)D concentrations were estimated by conditional logistic regression and combined by random-effects models. Circulating 25(OH)D increased from a median of 22.6 nmol/L in consortium-wide decile 1 to 93.2 nmol/L in decile 10. Breast cancer risk in each decile was not statistically significantly different from risk in decile 5 in models adjusted for breast cancer risk factors, and no trend was apparent (P-trend = 0.64). Compared to women with sufficient 25(OH)D based on Institute of Medicine guidelines (50- < 62.5 nmol/L), RRs were not statistically significantly different at either low concentrations (< 20 nmol/L, 3% of controls) or high concentrations (100- < 125 nmol/L, 3% of controls; ≥ 125 nmol/L, 0.7% of controls). RR per 25 nmol/L increase in 25(OH)D was 0.99 [95% confidence intervaI (CI) 0.95-1.03]. Associations remained null across subgroups, including those defined by body mass index, physical activity, latitude, and season of blood collection. Although none of the associations by tumor characteristics reached statistical significance, suggestive inverse associations were seen for distant and triple negative tumors. Circulating 25(OH)D, comparably measured in 17 international cohorts and season-standardized, was not related to subsequent incidence of invasive breast cancer over a broad range in vitamin D status.

Relationship between the subgingival microbiome and menopausal hormone therapy use: The Buffalo OsteoPerio study.

BACKGROUND: This study investigated the association between menopausal hormone therapy (HT) use and the subgingival microbiome, for which published information is limited. METHODS: This cross-sectional study included 1270 postmenopausal women, aged 53-81 years, who completed clinical examinations. Detailed information on HT use (type, delivery mode, duration) was obtained from questionnaires. HT use was categorized into three groups (never, former, current). 16S rRNA sequencing was performed on subgingival plaque samples obtained during dental examinations. Operational taxonomic units were centered log2-ratio (CLR) transformed to account for the compositional data structure. Analysis of variance was used to compare mean microbial relative abundances across HT categories with Benjamini-Hochberg correction. RESULTS: Significantly higher alpha diversity (Shannon Index) and beta diversity (Aitchison distance) was observed in never compared with current HT users (p < 0.05, each). Of the total 245 microbial taxa identified, 18 taxa differed significantly among the three HT groups, 11 of which were higher in current users and seven of which were lower in current users as compared with never users (p < 0.05, each). Differences in relative abundance between never and current HT users were materially unchanged after adjustment for age, body mass index, and oral hygiene. CONCLUSIONS: Relative abundance of several subgingival bacteria differed significantly between never and current HT users in a cohort of postmenopausal women. Additional studies are needed to determine the extent that these relationships might account for the previously reported inverse association between HT use and periodontal disease in older women.

Hepatitis C Virus Exposure and Infection in the Perinatal Period.

BACKGROUND: Hepatitis C virus infection is a leading cause of blood-borne hepatitis disease worldwide. Hepatitis C is a silent liver disease that, without treatment, leads to late-onset complications, including chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma, in 10-40% of patients. OBJECTIVE: This study aimed to review the epidemiology, clinical features, diagnosis, treatment, and prevention of hepatitis C among perinatally exposed children. METHODS: Public databases, including MEDLINE and PubMed, and websites from the Centers for Disease Control and Prevention, the Food and Drug Administration, the World Health Organization, and the National Institutes of Health were searched for relevant articles published between 2006 and 2021. RESULTS: The prevalence of hepatitis C has increased among women of childbearing age in the United States and is associated with risk factors, such as intravenous drug use, health inequities, and low socioeconomic background. Infants born to hepatitis C virus-infected mothers have a 6% risk of vertical transmission, and among those infected, 75% will develop chronic hepatitis C and late complications. However, hepatitis C-exposed infants are frequently lost to follow-up, and those infected have delayed diagnosis and treatment and are at high risk for late-onset complications. Direct- acting antivirals and the establishment of effective treatment guidelines cure hepatitis C virus infections. CONCLUSION: Hepatitis C predominantly affects underserved communities. Early screening of mothers and infants is critical for the diagnosis, treatment, and prevention of chronic infections and lateonset complications. New policies are needed to address hepatitis C health care inequities affecting mothers and infants in the United States.

Dietary carbohydrate intake is associated with the subgingival plaque oral microbiome abundance and diversity in a cohort of postmenopausal women.

Limited research exists on carbohydrate intake and oral microbiome diversity and composition assessed with next-generation sequencing. We aimed to better understand the association between habitual carbohydrate intake and the oral microbiome, as the oral microbiome has been associated with caries, periodontal disease, and systemic diseases. We investigated if total carbohydrates, starch, monosaccharides, disaccharides, fiber, or glycemic load (GL) were associated with the diversity and composition of oral bacteria in subgingival plaque samples of 1204 post-menopausal women. Carbohydrate intake and GL were assessed from a food frequency questionnaire, and adjusted for energy intake. The V3-V4 region of the 16S rRNA gene from subgingival plaque samples were sequenced to identify the relative abundance of microbiome compositional data expressed as operational taxonomic units (OTUs). The abundance of OTUs were centered log(2)-ratio transformed to account for the compositional data structure. Associations between carbohydrate/GL intake and microbiome alpha-diversity measures were examined using linear regression. PERMANOVA analyses were conducted to examine microbiome beta-diversity measures across quartiles of carbohydrate/GL intake. Associations between intake of carbohydrates and GL and the abundance of the 245 identified OTUs were examined by using linear regression. Total carbohydrates, GL, starch, lactose, and sucrose intake were inversely associated with alpha-diversity measures. Beta-diversity across quartiles of total carbohydrates, fiber, GL, sucrose, and galactose, were all statistically significant (p for PERMANOVA p < 0.05). Positive associations were observed between total carbohydrates, GL, sucrose and Streptococcus mutans; GL and both Sphingomonas HOT 006 and Scardovia wiggsiae; and sucrose and Streptococcus lactarius. A negative association was observed between lactose and Aggregatibacter segnis, and between sucrose and both TM7_[G-1] HOT 346 and Leptotrichia HOT 223. Intake of total carbohydrate, GL, and sucrose were inversely associated with subgingival bacteria alpha-diversity, the microbial beta-diversity varied by their intake, and they were associated with the relative abundance of specific OTUs. Higher intake of sucrose, or high GL foods, may influence poor oral health outcomes (and perhaps systemic health outcomes) in older women via their influence on the oral microbiome.

Red blood cell fatty acids and age-related macular degeneration in postmenopausal women.

PURPOSE: To evaluate the relationship between red blood cell (RBC) polyunsaturated fatty acid (PUFA) levels, and dietary PUFA and fish intake, with prevalent and incident age-related macular degeneration (AMD) in a US cohort of postmenopausal women. METHODS: This analysis included 1456 postmenopausal women from the Women's Health Initiative (WHI) Clinical Trials. RBC PUFAs were measured from fasting serum samples collected at WHI baseline. Dietary PUFAs and fish intake were assessed via food frequency questionnaires at baseline. There were 240 women who had prevalent AMD and 138 who self-reported AMD development over 9.5 years. Adjusted odds ratios and 95% confidence intervals were estimated for prevalent AMD by RBC PUFA levels, dietary PUFA intake, and frequency of fish consumption. Adjusted hazard ratios and 95% confidence intervals were estimated for incident AMD. A p-for-trend was estimated for continuous measures of dietary PUFA and fish intake. RESULTS: No significant association was found between prevalent or incident AMD and RBC docosahexaenoic acid (DHA) + eicosapentaenoic acid (EPA), EPA, DHA, alpha-linolenic acid (ALA), linoleic acid (LA), or arachidonic acid (AA). A positive association was found between dietary intake of AA and odds of prevalent AMD (p-for-trend for continuous AA intake = 0.02) and between intake of LA/ALA and incident AMD (p-for-trend for continuous ratio of LA/ALA intake = 0.03). No statistically significant associations were found between AMD and dietary intake of PUFAs or fish. CONCLUSIONS: RBC PUFAs were not associated with AMD in this cohort. Overall, dietary analyses of PUFAs supported this, excepting dietary AA intake and intake of LA in proportion to ALA of which there were trends of increased risk.

Sleep Quality and Dietary Patterns in an Occupational Cohort of Police Officers.

We examined the association between self-reported sleep quality, sleep duration, and dietary patterns among police officers in the Buffalo Cardio-Metabolic Occupational Stress (BCOPS) study.422 police officers aged 21-74 (2004-2009).We used a cross-sectional study design and obtained sleep quality and duration from responses to the 19-item Pittsburgh Sleep Quality Index. Using 46 energy-adjusted food groups derived from a 125-item food frequency questionnaire, we identified dietary patterns using exploratory factor analysis. Multiple linear regression analysis was used to examine the associations of sleep quality and duration with the derived dietary patterns.We identified major dietary patterns: fruits and vegetables (FV), dairy products, starches and fried foods, and meat and eggs. Individuals with poor sleep quality had a lower average FV score than those with optimal sleep (ß [SE] = -0.32 [0.13]; p = .01). Significant interactions were observed between sex and the FV and dairy products dietary patterns, where women with poor sleep quality had a lower mean FV score compared to women with optimal sleep quality (ß [SE] = -0.81 [0.29]; p = .01). Women with < 6 hours sleep duration had a lower mean dairy score compared to women with ≥ 7 hours sleep duration (ß [SE] = -0.69 [0.29]; p = .02). We did not observe these associations among men.Among women, good sleep quality and long sleep duration were associated with a dietary pattern high in consumption of both fruits and vegetables and dairy products.Abbreviations: BCOPS: Buffalo Cardio-Metabolic Occupational Stress study; BMI: body mass index; FFQ: food frequency questionnaire; FV: fruits and vegetables; KMO: Kaiser-Meyer-Olkin test; MET: metabolic equivalent of task score; PSQI: Pittsburgh Sleep Quality Index questionnaire.

Clinical and Lifestyle-Related Prognostic Indicators among Esophageal Adenocarcinoma Patients Receiving Treatment at a Comprehensive Cancer Center.

PURPOSE: The incidence of esophageal adenocarcinoma (EAC) has risen substantially in recent decades, while the average 5-year survival remains only ~20%. Disease stage and treatment are the strongest prognostic factors. The role of lifestyle factors in relation to survival remains uncertain, with a handful of studies to date investigating associations with obesity, smoking, physical activity, diet, or medications. METHODS: This study included patients diagnosed with primary adenocarcinoma of the esophagus, gastroesophageal junction, or cardia (N = 371) at Roswell Park Comprehensive Cancer Center between 2003 and 2019. Leveraging extensive data abstracted from electronic medical records, epidemiologic questionnaires, and a tumor registry, we analyzed clinical, behavioral, and environmental exposures and evaluated stage-specific associations with survival. Survival distributions were visualized using Kaplan-Meier curves. Cox proportional hazards regression models adjusted for age, sex, stage, treatment, and comorbidities were used to estimate the association between each exposure and all-cause or cancer-specific mortality. RESULTS: Among patients presenting with localized/regional tumors (stages I-III), current smoking was associated with increased overall mortality risk (HR = 2.5 [1.42-4.53], p = 0.002), while current physical activity was linked to reduced risk (HR = 0.58 [0.35-0.96], p = 0.035). Among patients with stage IV disease, individuals reporting pre-diagnostic use of statins (HR = 0.62 [0.42-0.92], p = 0.018) or NSAIDs (HR = 0.61 [0.42-0.91], p = 0.016) had improved overall survival. Exploratory analyses suggested that high pre-diagnostic dietary consumption of broccoli, carrots, and fiber correlated with prolonged overall survival in patients with localized/regional disease. CONCLUSION: Our data suggest that lifestyle exposures may be differentially associated with EAC survival based on disease stage. Future investigation of larger, diverse patient cohorts is essential to validate these findings. Our results may help inform the development of lifestyle-based interventions to improve EAC prognosis and quality of life.

Indices of Diet Quality and Risk of Lung Cancer in the Women's Health Initiative Observational Study.

BACKGROUND: Prospective evidence on associations between diet quality indices and lung cancer risk is limited, particularly among older women. OBJECTIVES: We investigated associations between 4 diet quality indices [Healthy Eating Index-2015 (HEI-2015), Alternate Healthy Eating Index 2010 (AHEI-2010), alternate Mediterranean Diet (aMED), and Dietary Approaches to Stop Hypertension (DASH)] and lung cancer incidence and mortality in the Women's Health Initiative Observational Study. METHODS: Postmenopausal women aged 50-79 y at baseline (1993-1998) self reported their diet intake and information on relevant covariates. We used Cox proportional hazards regression models to estimate HRs and 95% CIs after controlling for age, smoking, and other relevant covariates. RESULTS: During ∼17 y of follow-up among 86,090 participants, 1491 lung cancer cases and 1393 lung cancer deaths were documented. Dietary indices were not associated with overall lung cancer incidence but were protective against squamous cell carcinoma (12.8% of total lung cancer) cases (HEI-2015: HR: 0.85; 95% CI: 0.76, 0.96; AHEI-2010: HR: 0.87; 95% CI: 0.78, 0.98; aMED: HR: 0.90; 95% CI: 0.81, 0.99; DASH: HR: 0.87; 95% CI: 0.77, 0.98). Among the indices, only HEI-2015 showed an inverse trend (P-trend = 0.02) with overall lung cancer mortality. Smoking status or participant age at baseline did not modify the association between dietary indices and lung cancer incidence or mortality. CONCLUSIONS: After comprehensive control of smoking exposure, we found that diet quality was not associated with overall lung cancer among postmenopausal women. However, a high-quality diet was inversely related to incident lung cancer of the squamous cell subtype. Future studies in populations with diverse age, smoking history, and dietary intake may further elucidate the relation between diet quality indices and lung cancer, especially by histological subtype.

Plasma 25-Hydroxyvitamin D Concentrations and Serum and Salivary C-Reactive Protein in the Osteoporosis and Periodontal Disease Study.

Vitamin D has been hypothesized to play an important role in preventing the development and progression of periodontal disease, but the underlying immune modulatory mechanisms remain understudied. We examined the cross-sectional association between biomarkers of vitamin D status and C-reactive protein (CRP) among postmenopausal women aged 53-81 years. Linear regression was used to examine the association between plasma 25-hydroxyvitamin D (25[OH]D) concentrations, a biomarker of vitamin D status, and both salivary and serum CRP concentrations in 567 women from the Buffalo Osteoporosis and Periodontal Disease (OsteoPerio) Study (1997-2000). CRP concentrations were measured with multiplex arrays and transformed for normality using the natural log. Concentrations above and below the limit of detection were included in analysis as right- and left-censored observations. An inverse association was observed between 25(OH)D and salivary CRP in a model adjusted for age, smoking status, frequency of tooth brushing and flossing, and hormone therapy use (-7.56% difference in salivary CRP concentrations per 10 nmol/L increase in 25(OH)D, 95% CI: -12.78 to -2.03). Further adjustment for percent body fat attenuated this association (-2.48%, 95% CI: -7.88 to 3.24). No significant associations were found between 25(OH)D and serum CRP. Plasma vitamin D concentrations were not associated with salivary or serum CRP concentrations in this cohort of postmenopausal women.
