Can allostatic load in pregnancy explain the association between race and subsequent cardiovascular disease risk: A cohort study.

OBJECTIVE: To assess the relationship between allostatic load, a measure of cumulative chronic stress in early pregnancy and cardiovascular disease risk, 2-7 years postpartum, and pathways contributing to racial disparities in cardiovascular disease risk. DESIGN: Secondary analysis of a prospective cohort study. SETTING MULTICENTER POPULATION: Pregnant women. METHODS: Our primary exposure was high allostatic load in the first trimester, defined as at least 4 of 12 biomarkers (systolic blood pressure, diastolic blood pressure, body mass index, cholesterol, low-density lipoprotein, high-density lipoprotein, high-sensitivity C-reactive protein, triglycerides, insulin, glucose, creatinine and albumin) in the unfavourable quartile. Logistic regression was used to test the association between high allostatic load and main outcome adjusted for confounders: time from index pregnancy and follow up, age, education, smoking, gravidity, bleeding in the first trimester, index adverse pregnancy outcomes, and health insurance. Each main outcome component and allostatic load were analysed secondarily. Mediation and moderation analyses assessed the role of high allostatic load in racial disparities of cardiovascular disease risk. MAIN OUTCOME MEASURE: Incident cardiovascular disease risk: hypertension, or metabolic disorders. RESULTS: Cardiovascular disease risk was identified in 1462/4022 individuals (hypertension: 36.6%, metabolic disorder: 15.4%). After adjustment, allostatic load was associated with cardiovascular disease risk (adjusted odds ratio [aOR] 2.0, 95% CI 1.8-2.3), hypertension (aOR 2.1, 95% CI 1.8-2.4) and metabolic disorder (aOR 1.7, 95% CI 1.5-2.1). Allostatic load was a partial mediator between race and cardiovascular disease risk. Race did not significantly moderate this relationship. CONCLUSIONS: High allostatic load during pregnancy is associated with cardiovascular disease risk. The relationships between stress, subsequent cardiovascular risk and race warrant further study.

Non-invasive digital thermal monitoring and flow-mediated dilation in systemic sclerosis.

OBJECTIVES: The fingers, toes, and tips of the nose and ears have specialised structural and functional features for thermoregulation, and are the most common areas of Raynaud's phenomenon in systemic sclerosis. Digital thermal monitoring (DTM) of vascular reactivity assesses Doppler ultrasound hyperemic, low frequency, blood velocity of radial artery and fingertip vascular function. Flow mediated dilation (FMD) is an indirect measure of endothelial function, perfusion, and vasodilator ability. In this study, we investigated the cross-sectional correlation of FMD and DTM variables to inform an optimised noninvasive study of SSc endothelial function. A student's T-test was used to compare means of DTM across binary variables. METHODS: Consented SSc registry patients were included in this analysis. The subjects were prepared for FMD and DTM per standardised guidelines. The SSc clinical features were recorded. Spearman's Rank Correlation was used to assess the strength of a relationship FMD and DTM variables. RESULTS: Thirty-four SSc subjects had FMD and DTM performed on the same day. Relative (0.42, p=<0.02), absolute FMD (0.41, p<0.02), and shear rate (0.32, p<0.07) were weakly, but significantly correlated with the DTM. Reactive hyperemia (-0.44, p=0.000) was weakly inversely, but significantly related with DTM. Baseline diameter and flow were not significantly related to the DTM. CONCLUSIONS: This non-invasive study of SSc endothelial function suggests that macrocirculation (including relative and absolute FMD, shear rate, and peak hyperemia) and microcirculatory thermoregulation (characterised by DTM) are significantly correlated, thus warrants further prospective study.

Implications of endothelial shear stress on systemic sclerosis vasculopathy and treatment.

There are no Federal Drug Administration approved drugs for the treatment of systemic sclerosis vascular digital ulcers (DU) in the United States, which are thought to be an end-stage result of prolonged ischaemia due to severe, prolonged Raynaud's phenomenon. Most therapeutics for vasodilation used in SSc work different pathways to target the smooth muscle to induce vessel relaxation. Longitudinal studies of vascular function allow insight into the effects of medications used for Raynaud's phenomenon in the SSc patient population. In this review, we discuss vascular tone, the function of the endothelium in SSc, and provide the rationale for longitudinal studies of vascular function and therapeutics that target the endothelial shear stress in addition to vasodilation for treatment and prevention of DU. This review provides the rationale for vasodilatory medication use for treatment of SSc-related DU and justifies access to non-FDA approved medications for this indication.

Evaluation of childhood nutrition by dietary survey and stable isotope analyses of hair and breath.

OBJECTIVES: The natural abundances of carbon, nitrogen, and sulfur stable isotopes in hair, and of carbon isotopes in breath serve as quantitative biomarkers of protein and carbohydrate sources, but applicability of isotopes for evaluating children's diet has not been demonstrated. In this study, we sought to describe the stable isotope patterns observed in the hair and breath of children and to assess dietary variations in relation to age and ethnicity, hypothesizing that these would reflect dietary differences across age and ethnic groups and would correlate with intake variables derived from a Food Frequency Questionnaire. METHODS: Data were obtained from a cross-sectional study of non-Hispanic white (N = 115) and Hispanic (N = 97) children, aged 9-16 years, in Salt Lake City, Utah. Sampling included a hair sample, breath samples (AM and PM), and a youth/adolescent food questionnaire (YAQ). Hair was analyzed for carbon (δ13 C), nitrogen (δ15 N), and sulfur (δ34 S) isotopes, and breath samples for δ13 CAM/PM of respired CO2 . RESULTS: Non-Hispanic whites had lower δ13 C, δ15 N, δ13 CAM , and δ13 CPM values than Hispanics. Hair δ13 C and δ15 N values were correlated with protein sources, particularly for non-Hispanics. Breath δ13 C values were correlated with carbohydrate sources, particularly for Hispanic students. Non-Hispanic white students reported greater intake of total protein, animal protein, dairy, and grain than Hispanic students. Hispanic students reported higher intake of carbohydrates, particularly sweetened beverages. CONCLUSION: While YAQ and stable isotope data reflected strong cultural influences in diet, no significant gender-based nor age-based differences were detected. Significant covariation between YAQ and isotopes existed and demonstrate the potential of stable isotopes for characterizing children's diet.

Sublingual Abnormalities in Systemic Sclerosis.

BACKGROUND: Sublingual frenulum abnormalities have been observed in systemic sclerosis (SSc), but the clinical significance of such features is not known. The goal of this project was to devise a reliable bedside tool to confirm the presence of sublingual frenulum abnormalities in SSc and explore potential associations with patient demographics and gastrointestinal clinical phenotype. METHODS: A working group was created to develop a semiquantitative assessment tool for assessing sublingual abnormalities, the Sublingual Abnormalities Index (SAI). Sublingual frenulum thickness, frenulum length, sublingual buccal mucosa pallor, and the presence of oral telangiectasia were each individually scored using 0- to 2-point Likert scales and a composite score of the 4 domains created by summation of the individual scores. Assessment of the sublingual region of 21 patients with SSc and 8 control subjects was undertaken. An image of the sublingual frenulum was obtained using prespecified camera settings to allow assessment of interrater reliability with 2 independent blinded assessors. RESULTS: Scores for each of the SAI domains differed between control subject and SSc population (P = 0.0003). Patients with SSc had a composite SAI score of 4.3 (SD, 0.37). None of the control subjects had a composite SAI score of more than 2. There was excellent interrater reliability between clinician assessment and each blinded assessor (Cohen κ's of 0.72 and 0.82, respectively). CONCLUSIONS: This feasibility study confirms the presence of clinical sublingual abnormalities in SSc, which can be categorized using a simple scoring chart with moderate to near-perfect interrater agreement. The functional significance and pathogenesis of this abnormality warrant further study.

Regular expression-based learning to extract bodyweight values from clinical notes.

BACKGROUND: Bodyweight related measures (weight, height, BMI, abdominal circumference) are extremely important for clinical care, research and quality improvement. These and other vitals signs data are frequently missing from structured tables of electronic health records. However they are often recorded as text within clinical notes. In this project we sought to develop and validate a learning algorithm that would extract bodyweight related measures from clinical notes in the Veterans Administration (VA) Electronic Health Record to complement the structured data used in clinical research. METHODS: We developed the Regular Expression Discovery Extractor (REDEx), a supervised learning algorithm that generates regular expressions from a training set. The regular expressions generated by REDEx were then used to extract the numerical values of interest. To train the algorithm we created a corpus of 268 outpatient primary care notes that were annotated by two annotators. This annotation served to develop the annotation process and identify terms associated with bodyweight related measures for training the supervised learning algorithm. Snippets from an additional 300 outpatient primary care notes were subsequently annotated independently by two reviewers to complete the training set. Inter-annotator agreement was calculated. REDEx was applied to a separate test set of 3561 notes to generate a dataset of weights extracted from text. We estimated the number of unique individuals who would otherwise not have bodyweight related measures recorded in the CDW and the number of additional bodyweight related measures that would be additionally captured. RESULTS: REDEx's performance was: accuracy=98.3%, precision=98.8%, recall=98.3%, F=98.5%. In the dataset of weights from 3561 notes, 7.7% of notes contained bodyweight related measures that were not available as structured data. In addition 2 additional bodyweight related measures were identified per individual per year. CONCLUSION: Bodyweight related measures are frequently stored as text in clinical notes. A supervised learning algorithm can be used to extract this data. Implications for clinical care, epidemiology, and quality improvement efforts are discussed.

Autophagy is a key feature in the pathogenesis of systemic sclerosis.

Autophagosomes are formed during autophagy, which is activated by hypoxia and starvation. Autophagy is important for mast cell degranulation. We hypothesized that autophagy is a key feature in the pathogenesis of systemic sclerosis (SSc). We examined SSc clinical features and mast cell density across the presence and severity of autophagy. Skin punch biopsy was performed on 33 SSc patients and 6 healthy controls (HC). Autophagy was evaluated by immunofluorescence on paraffin sections using LC3-FITC staining on these patients. The intensity of staining and mast cell density was examined across clinical features in 19 of the SSc patients. Presence of autophagosome formation was assessed by EM in 17 of the SSc patients and 4 HC. In our SSc study population, 29 of subjects were female and 23 were limited cutaneous. Twenty-nine of 33 SSc patients had autophagy by LC3-FITC staining. Intensity of staining decreased with longer duration of SSc (p = 0.09) and RP (p = 0.10). Bloating and distention differed across level of intensity staining (Wilcoxon signed-rank test, p = 0.05), with the greatest levels among those with moderate intensity. On EM, autophagosome formation was present in 16 of 17 SSc patients and no HC. All SSc patients had perivascular mast cells. Autophagy was present in 29 of 33 SSc patients, and none of our HC suggesting importance in pathogenesis. Autophagy staining was greater among those with shorter duration of SSc. Bloating and distention were higher in patients with moderate autophagy staining. Perivascular mast cells were present in all SSc patients. The role of autophagy in vasculopathy and mast cell activation in SSc warrants further studies.

Expanding the Treatment Team: What Is the Role for Occupational Therapy, Physical Therapy, Wound Care, and Nutritional Support in Systemic Sclerosis?

The optimal systemic sclerosis (SSc) care plan includes an occupational therapist and physical therapist as well as wound care experts and a registered dietitian if indicated. Screening instruments for functional and work disability, hand and mouth limitations, malnutrition, and dietary intake can identify the need for ancillary support services. Telemedicine can assist in developing effective ancillary treatment plans. Reimbursement for services may limit access for patients with SSc to expand their care team but a focus on prevention rather than management of damage is recognized as an important unmet need in SSc. In this review, the role of a comprehensive care team for SSc is discussed.

High dietary fiber intake is associated with decreased inflammation and all-cause mortality in patients with chronic kidney disease.

Chronic kidney disease is considered an inflammatory state and a high fiber intake is associated with decreased inflammation in the general population. Here, we determined whether fiber intake is associated with decreased inflammation and mortality in chronic kidney disease, and whether kidney disease modifies the associations of fiber intake with inflammation and mortality. To do this, we analyzed data from 14,543 participants in the National Health and Nutrition Examination Survey III. The prevalence of chronic kidney disease (estimated glomerular filtration rate less than 60 ml/min per 1.73 m(2)) was 5.8%. For each 10-g/day increase in total fiber intake, the odds of elevated serum C-reactive protein levels were decreased by 11% and 38% in those without and with kidney disease, respectively. Dietary total fiber intake was not significantly associated with mortality in those without but was inversely related to mortality in those with kidney disease. The relationship of total fiber with inflammation and mortality differed significantly in those with and without kidney disease. Thus, high dietary total fiber intake is associated with lower risk of inflammation and mortality in kidney disease and these associations are stronger in magnitude in those with kidney disease. Interventional trials are needed to establish the effects of fiber intake on inflammation and mortality in kidney disease.

Dietary phosphorus intake and mortality in moderate chronic kidney disease: NHANES III.

BACKGROUND: Dietary phosphorus intake is usually restricted in dialysis patients but the associations of dietary phosphorus intake with mortality in moderate chronic kidney disease (CKD) are unknown. Therefore, we examined these associations in National Health and Nutrition Examination Survey III. METHODS: Dietary phosphorus intake was estimated from 24-h dietary recalls administered by trained personnel. CKD was defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m(2). Time to mortality was examined by Cox regression models taking into account the complex survey design. RESULTS: 1105 adults with CKD were studied. Phosphorus intake was 1033 ± 482 mg/day (mean ± SD), eGFR was 49.3 ± 9.5 mL/min/1.73 m(2) and serum phosphorus was 3.5 ± 0.5 mg/dL. Compared to those in the lowest tertile of phosphorus intake (mean 532 ± 161 mg/day), those in the highest third (1478 ± 378 mg/day) had similar serum phosphorus levels (3.6 ± 0.5 versus 3.5 ± 0.6 mg/dL, P = 0.113) and modestly higher eGFR (50.0 ± 8.1 versus 47.5 ± 12.0 mL/min/1.73 m(2), P = 0.014). After adjustment for demographics, comorbidity, eGFR, physical activity, energy intake and nutritional variables, phosphorus intake was not associated with mortality [hazard ratio (HR) 0.98 per 100 mg/dL increase, 0.93-1.03]. CONCLUSIONS: High dietary phosphorus intake is not associated with increased mortality in moderate CKD, presumably because serum phosphorus levels are maintained in the normal range at this level of GFR. Interventional trials are needed to define optimal phosphorus intake in moderate CKD.

Pelvic Floor Support and Symptoms 1 Year Postpartum in Relation to Excess Body Habitus Before, During and After First Vaginal Birth.

IMPORTANCE: Obesity may be a modifiable risk factor for pelvic floor disorders. OBJECTIVES: The objective of this study is to determine associations between weight, weight changes, and cumulative exposure to excess body mass index (BMI) from prepregnancy to 1 year postpartum on pelvic floor support and symptoms 1 year after first vaginal birth. STUDY DESIGN: In 645 primiparous women who gave birth vaginally, we assessed anatomic pelvic floor support, pelvic floor symptoms and BMI at the third trimester, 5 - 10 weeks, and 1 year postpartum; we also assessed BMI prepregnancy and predelivery. Using multivariable models, we determined associations between pelvic floor outcomes 1 year postpartum and BMI quartiles at different timepoints, gestational weight gain, and postpartum weight retention. We evaluated associations between stress urinary incontinence (SUI) and moderate/severe urinary incontinence (UI) 1 year postpartum and cumulative excess BMI from prepregnancy to 1-year postpartum (BMI1year). RESULTS: Body mass index was not associated with anatomic support, composite symptom burden, overactive bladder, anal incontinence, or constipation at any timepoint. Gestational weight gain and postpartum weight retention were not associated with any 1-year outcome. Body mass index at every timepoint was positively associated with SUI and moderate/severe UI; BMI1year was most predictive. Cumulative excess BMI was positively associated with SUI and moderate/severe UI but only slightly more predictive of these outcomes than BMI1year alone. CONCLUSIONS: Body mass index over the pregnancy trajectory was not associated with outcomes other than UI. The small advantage of cumulative exposure to excess BMI over BMI1year in predicting SUI and moderate/severe UI suggests that BMI1year adequately captures risk of these 1-year outcomes.

Randomized, Double-Blind Placebo-Controlled Trial to Assess the Effect of Probiotics on Irritable Bowel Syndrome in Veterans With Gulf War Illness.

Background: Many veterans who served in Operation Desert Storm (August 1990 to March 1991) experienced a complex of symptoms of unknown etiology called Gulf War illness (GWI), which significantly impacts the health and quality of life (QOL) and may have contributed to irritable bowel syndrome (IBS). Methods: We performed a prospective, double-blind placebocontrolled study to determine the efficacy of the multistrain De Simone Formulation probiotic containing 8 strains of bacteria on symptoms of IBS and GWI. Veterans of Operation Desert Storm who had IBS and ≥ 2 nonintestinal symptoms of GWI were included. The primary study endpoint was change in bowel symptom score. The secondary endpoints were mean change in symptoms, QOL, and extra-intestinal and posttraumatic stress disorder (PTSD) symptoms. Results: A total of 101 Gulf War veterans with IBS and GWI were screened at the Veteran Affairs Medical Center in Salt Lake City, Utah. The study was completed by 53 veterans; 47 (89%) were male with a mean (SD) age of 55 (8) years. The probiotic did not improve IBS symptoms or other extra-intestinal symptoms common to IBS and GWI. Conclusions: Our study did not demonstrate statistically significant improvement in IBS symptoms or QOL after treatment with the probiotic. We also did not find any improvement in symptoms of GWI or PTSD.

Allostatic Load and Adverse Pregnancy Outcomes.

OBJECTIVE: To assess the association between allostatic load, as an estimate of chronic stress, and adverse pregnancy outcomes. METHODS: This was a secondary analysis of nuMoM2b (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be), a prospective observational cohort study. Our primary exposure was dichotomous high allostatic load in the first trimester, defined as 4 or more of 12 biomarkers in the "worst" quartile. The primary outcome was a composite adverse pregnancy outcome: hypertensive disorders of pregnancy (HDP), preterm birth, small for gestational age (SGA), and stillbirth. Secondary outcomes included components of the composite. Multivariable logistic regression was used to test the association between high allostatic load and adverse pregnancy outcomes, adjusted for potential confounders. Mediation and moderation analyses were conducted to assess the role of allostatic load along the causal pathway between racial disparities and adverse pregnancy outcomes. RESULTS: Among 4,266 individuals, 34.7% had a high allostatic load. Composite adverse pregnancy outcome occurred in 1,171 (27.5%): 14.0% HDP, 8.6% preterm birth (48.0% spontaneous and 52.2% indicated), 11.0% SGA, and 0.3% stillbirth. After adjustment for maternal age, gravidity, smoking, bleeding in the first trimester, and health insurance, high allostatic load was significantly associated with a composite adverse pregnancy outcome (adjusted odds ratio [aOR] 1.5, 95% CI 1.3, 1.7) and HDP (aOR 2.5, 95% CI 2.0-2.9), but not preterm birth or SGA. High allostatic load partially mediated the association between self-reported race and adverse pregnancy outcomes. The association between allostatic load and HDP differed by self-reported race, but not for a composite adverse pregnancy outcome, preterm birth, or SGA. CONCLUSION: High allostatic load in the first trimester is associated with adverse pregnancy outcomes, particularly HDP. Allostatic load was a partial mediator between race and adverse pregnancy outcomes. The association between allostatic load and HDP differed by self-reported race.

Macronutrient composition influence on breast cancer risk in Hispanic and non-Hispanic white women: the 4-Corners Breast Cancer Study.

The association of dietary macronutrient composition with risk of breast cancer is not well understood. We investigated the macronutrient composition of diet in the 4-Corners Breast Cancer Study. Logistic regression models were used for case-control comparisons adjusted for age, center, education, smoking, total activity, calories, dietary fiber, dietary calcium, height, parity, recent hormone exposure, reference year body mass index (BMI), and the interaction of BMI and recent hormone exposure. Breast cancer risk declined with increasing dietary fat and increased with carbohydrates similarly across ethnicity and menopausal status. Associations of carbohydrate (direct) and fat (inverse), particularly saturated and monounsaturated fat, with breast cancer were present among normal and overweight postmenopausal women and absent among obese postmenopausal women. No substantive differences were noted in the association of macronutrients with risk of breast cancer between non-Hispanic white and Hispanic women. Associations of the macronutrients carbohydrate and fat with breast cancer risk were attenuated among postmenopausal obese women.

Oral clefts and maternal biomarkers of folate-dependent one-carbon metabolism in Utah.

BACKGROUND: Maternal folate intake and related biomarkers have been inconsistently associated with a risk of oral clefts. METHODS: Maternal concentrations of plasma folate (PF) and erythrocyte folate (EF), plasma pyridoxal-5'-phosphate (PLP; active vitamin B(6) ) and total plasma homocysteine (tHcy) were measured in a Utah study with 347 cases and 469 controls. RESULTS: Risk of all clefts combined, including cleft lip with or without cleft palate (CL/P) and cleft palate only (CP), was 65% lower in the highest versus lowest PF quartile (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.23-0.53; p-trend < 0.001). Results remained significant in the subgroups with isolated CL/P and CP (p-trend < 0.001 in each). EF results were similar. In the highest versus lowest PLP quartile, risk of CP with other malformations was lower (OR, 0.25; 95% CI, 0.07-0.95); however, no other associations were significant for PLP or tHcy. Differences in mean biomarker levels between cases and controls widened with an increasing interval between delivery and maternal blood collection. Decreased cleft risk with increasing quartiles of PF, EF, and PLP and decreasing tHcy was more apparent in mothers with a longer versus shorter interval between the index child delivery and blood collection. CONCLUSION: Low maternal blood folate concentration was associated with an increased risk of clefts, and the differences in mean case and control PF, EF, PLP, and tHcy concentrations widened over time. Additional mechanistic studies are warranted to elucidate whether an acquired or inherited disorder of folate metabolism plays a role in the etiology of clefts.

Probiotics for the treatment of systemic sclerosis-associated gastrointestinal bloating/ distention.

OBJECTIVES: Treatment for gastrointestinal tract (GIT) disease in systemic sclerosis (SSc) is challenging as no immunosuppressive or anti-fibrotic therapy is available with clearly proven efficacy. Probiotics are viable, non-pathogenic microorganisms that are hypothesized to improve the composition of the intestinal microbiota from a potentially harmful composition to a composition that is beneficial to the host. Our hypothesis is that GIT symptoms in SSc patients with moderate bloating would improve with probiotic implementation. METHODS: Ten patients with a moderate-to-severe distention/bloating score (1.25-3.00) on the University of California Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 (UCLA SCTC GIT 2.0), but otherwise stable organ disease not requiring any medication adjustment were recruited from the University of Utah Scleroderma Center. We compared the GIT 2.0 scores at baseline and after 2 months of use of Align (bifidobacterium infantis; 109 CFU per capsule) or Culturelle (lactobacillus GG; 109 CFU per capsule) using paired t-test and calculated effect size (ES). RESULTS: Significant improvement in total GIT 2.0 score (ES = 0.82), reflux (ES = 0.33), bloating/distention (ES = 1.76), and emotional scales (ES = 0.18) were reported after two months of daily probiotic use. CONCLUSIONS: This pilot study suggests probiotics significantly improve the reflux, distention/ bloating, and total GIT scales in SSc patients. As hypothesized, the largest effect was seen in distention/bloating scale. Probiotics may be useful for treatment of SSc-associated distention/ bloating.

The possible impact of increased physical intimate partner violence during the COVID-19 pandemic on ocular health.

During the COVID-19 outbreak, sheltering at home has led to an increase in physical intimate partner violence cases. Intimate partner violence-sustained ocular injuries may be higher during the pandemic due to the increase in physical intimate partner violence. Left untreated, intimate partner violence-related ocular or orbital trauma can lead to permanent vision loss. Even with treatment, patients often lose vision from intimate partner violence-related traumatic ocular injuries. Eye care providers and eye care facilities should understand the community services available to intimate partner violence survivors to better care for these patients. Due to the potential lasting economic burden and social strain of this pandemic, eye care providers and facilities should stay vigilant as there may still be a sustained increase in intimate partner violence even after the global COVID-19 pandemic.

The frequency of Raynaud's phenomenon, very early diagnosis of systemic sclerosis, and systemic sclerosis in a large Veteran Health Administration database.

BACKGROUND: We describe Raynauds phenomenon (RP), potential very early diagnosis of systemic sclerosis (VEDOSS), and systemic sclerosis (SSc) in Veterans deployed in support of Post-9/11 operations. We sought to describe the military occupation specialty, clinical features, and vasodilator use across the three diagnoses. METHODS: Individual Veterans medical records were assessed for RP (ICD-9443.0), VEDOSS with swelling of hands (ICD-9729.81) and RP (ICD-9443.0), and SSc (ICD-9710.1). The distribution of sociodemographic, military service branch, job classification, vasodilator use, and comorbidities were examined across the three classifications of disease. The chi-squared test and Fisher's exact compared frequency of these categorical variables. Logistic regression assessed the likelihood of characteristics of the three classifications. RESULTS: In this population of 607,665 individual Veteran medical records, 857 had RP, 45 met possible VEDOSS criteria, and 71 had a diagnosis of SSc. The majority of RP, potential VEDOSS and SSc cases were white males. Those in craftworks, engineering or maintenance, and healthcare had a greater likelihood of RP. Less than half of RP and VEDOSS patients were on vasodilators. The most common comorbidities in this population were the diagnostic code for pain (highest in the potential VEDOSS group [81.6%]), followed by depression in all groups. CONCLUSION: This is a unique Veteran population of predominately-male patients. Our data suggests that vasodilator medications are potentially being under-utilized for RP and potential VEDOSS. Our data highlights mood and pain management as an important aspect of SSc care.

Habitus and Pelvic Floor Symptoms and Support 1 Year Postpartum.

OBJECTIVE: To estimate the association between habitus measures and pelvic floor support and symptoms in primiparous women 1 year after term vaginal delivery. METHODS: In this cross-sectional study including women enrolled at seven academic and community sites, we assessed pelvic floor support, weight, height, waist circumference, and percent fat using air displacement plethysmography and participants completed questionnaires, all at one year postpartum. We tested the association of quintiles of habitus measure, including body mass index (BMI), waist circumference, percent body fat, and waist/height ratio, with the primary outcomes: anatomic support, dichotomized as maximal vaginal descent less than 0 cm (better support) compared with 0 cm or more (worse support) per the pelvic organ prolapse quantification examination and symptom burden (positive with bothersome symptoms in two or more of six symptom domains), and on five secondary outcomes. The sample size provides 90% power to detect odds ratios (ORs) of 1.78 or greater between women at mean compared with mean+1 SD of habitus measure. RESULTS: Of 592 participants, 55 (9.3%) demonstrated worse support and 321 (54.2%) symptom burden. In multivariable analyses, habitus measures were not significantly associated with anatomic support or, except for the highest waist/height ratio quintile, with symptom burden. Compared with women in the first quintile of each habitus measure, those in most higher quintiles demonstrated elevated odds of moderate to severe urinary incontinence (UI); increased odds for stress urinary incontinence (SUI) were mainly limited to the highest quintile. After adjusting for percent body fat, the increased odds for BMI on SUI (OR 2.47, 95% CI 1.43-4.28) were no longer significant (OR 1.38, 95% CI 0.54, 3.51). CONCLUSION: Habitus in primiparous patients at 1 year postpartum was not associated with anatomic support or symptom burden. Habitus was more associated with moderate to severe UI than mild UI. The association of higher BMI with SUI was attenuated by fitness, reflected by fat percentage.

Pseudoexfoliation and Cataract Syndrome Associated with Genetic and Epidemiological Factors in a Mayan Cohort of Guatemala.

The Mayan population of Guatemala is understudied within eye and vision research. Studying an observational homogenous, geographically isolated population of individuals seeking eye care may identify unique clinical, demographic, environmental and genetic risk factors for blinding eye disease that can inform targeted and effective screening strategies to achieve better and improved health care distribution. This study served to: (a) identify the ocular health needs within this population; and (b) identify any possible modifiable risk factors contributing to disease pathophysiology within this population. We conducted a cross-sectional study with 126 participants. Each participant completed a comprehensive eye examination, provided a blood sample for genetic analysis, and received a structured core baseline interview for a standardized epidemiological questionnaire at the Salama Lions Club Eye Hospital in Salama, Guatemala. Interpreters were available for translation to the patients' native dialect, to assist participants during their visit. We performed a genome-wide association study for ocular disease association on the blood samples using Illumina's HumanOmni2.5-8 chip to examine single nucleotide polymorphism SNPs in this population. After implementing quality control measures, we performed adjusted logistic regression analysis to determine which genetic and epidemiological factors were associated with eye disease. We found that the most prevalent eye conditions were cataracts (54.8%) followed by pseudoexfoliation syndrome (PXF) (24.6%). The population with both conditions was 22.2%. In our epidemiological analysis, we found that eye disease was significantly associated with advanced age. Cataracts were significantly more common among those living in the 10 districts with the least resources. Furthermore, having cataracts was associated with a greater likelihood of PXF after adjusting for both age and sex. In our genetic analysis, the SNP most nominally significantly associated with PXF lay within the gene KSR2 (p < 1 × 10-5). Several SNPs were associated with cataracts at genome-wide significance after adjusting for covariates (p < 5 × 10-8). About seventy five percent of the 33 cataract-associated SNPs lie within 13 genes, with the majority of genes having only one significant SNP (5 × 10-8). Using bioinformatic tools including PhenGenI, the Ensembl genome browser and literature review, these SNPs and genes have not previously been associated with PXF or cataracts, separately or in combination. This study can aid in understanding the prevalence of eye conditions in this population to better help inform public health planning and the delivery of quality, accessible, and relevant health and preventative care within Salama, Guatemala.
