Home Blood Pressure Monitoring in Women of Child-Bearing Age With Hypertension From 2009 to 2014

BACKGROUND

Hypertension (HTN) is a leading cause of maternal mortality, and HTN guidelines recommend home blood pressure monitoring (HBPM) to help achieve blood pressure (BP) control. Evidence suggests that HBPM be coupled with a care team to maximize its effectiveness. HBPM use and the prevalence of provider counseling in child-bearing age women with HTN are unknown.

METHODS

We used data from 3,614 women in the cross-sectional National Health and Nutrition Examination Surveys 2009-2014 to determine HBPM use and provider counseling for women of child-bearing age (20-50 years) with and without HTN. HBPM use and provider counseling were self-reported. We examined rates of HBPM use by race/ethnicity, poverty-income ratio (PIR), education, and insurance.

RESULTS

Among women of child-bearing age with HTN, the mean (SE) age was 37.0 (0.3) years, the mean (SE) BMI was 35.5 (0.6) kg/m2, and 73% were on BP medication. Of these women with HTN, 49.6% reported HBPM use in the past year and 40.4% received provider counseling. There was no significant difference in HBPM use by race/ethnicity, PIR, or insurance, though higher education was associated with HBPM use. Women with HTN who received provider counseling were more likely to use HBPM (odds ratio = 15.7, 95% confidence interval 9.1-26.9).

CONCLUSIONS

Nearly half of child-bearing age women with HTN have adopted HBPM, and provider counseling was strongly associated with HBPM use. This highlights a need and opportunity for providers to improve BP management by supporting a popular and valuable monitoring approach among women of child-bearing age with HTN.

Developing a curriculum to improve cardiology fellows' training in pregnancy and cardiovascular disease

BACKGROUND

Exposure to pregnant women with cardiovascular disease (CVD) during cardiology fellowship training is limited and without a standard curriculum in the United States. The authors sought to evaluate a dedicated curriculum to teach management of CVD in pregnancy to improve general cardiology fellowship training.

METHODS

The authors developed a dedicated CVD in pregnancy curriculum for the general cardiology fellows at a large academic medical center in the fall of 2019. Fellows' knowledge was assessed via a board-style examination and exposure and attitudes related to the care of pregnant women with CVD were evaluated with a needs assessment questionnaire before and after the curriculum.

RESULTS

Of the 17 fellows who participated in the curriculum, 12 completed the needs assessment pre-curriculum and 9 post-curriculum. The mean (SD) number of pregnant women with CVD cared for by each fellow in the inpatient and outpatient settings were 0.75 (1.29) and 0.56 (0.73), respectively. After the curriculum, all fellows reported awareness of available resources to treat pregnant women with CVD, while a majority disagreed that they receive regular exposure to pregnant patients with CVD in their training. The authors observed significant increases in fellows' confidence in their knowledge of normal cardiovascular physiology of pregnancy, physical exam skills, and ability to care for pregnant women with valvular disease and arrhythmias from pre to post-curriculum. A total of 15 fellows completed the board-style exam pre-curriculum and 15 post-curriculum. Fellows' performance on the board-style examination improved slightly from before to after the curriculum (64.0 to 75.3% correct, p = 0.02).

CONCLUSIONS

A dedicated curriculum improved cardiology fellows' knowledge to recognize and treat CVD in pregnancy and improved confidence in caring for this unique patient population.

Dietary Habits and Medications to Control Hypertension Among Women of Child-Bearing Age in the United States from 2001 to 2016

BACKGROUND

Hypertension (HTN) in pregnancy is a leading cause of maternal morbidity and mortality in the United States. Although the Dietary Approaches to Stop Hypertension (DASH) diet is recommended for all adults with HTN, rates of DASH adherence and antihypertensive medication use in women of child-bearing age are unknown. Our objectives were to determine DASH adherence and antihypertensive medication use in women of child-bearing age.

METHODS

In the National Health and Nutrition Examination Surveys from 2001 to 2016, we estimated DASH adherence among women of child-bearing age (20-50 years). We derived a DASH score (0-9) based on 9 nutrients, with DASH adherence defined as DASH score ≥4.5. HTN was defined by blood pressure (BP) ≥130/80 mm Hg or antihypertensive medication use. DASH scores were compared across BP categories and antihypertensive medication use was categorized.

RESULTS

Of the 7,782 women, the mean age (SE) was 32.8 (0.2) years, 21.4% were non-Hispanic Black, and 20.3% had HTN. The mean DASH score was 2.11 (0.06) for women with self-reported HTN and 2.40 (0.03) for women with normal BP (P < 0.001). DASH adherence was prevalent in 6.5% of women with self-reported HTN compared with 10.1% of women with normal BP (P < 0.05). Self-reported HTN is predominantly managed with medications (84.8%), while DASH adherence has not improved in these women from 2001 to 2016. Moreover, 39.5% of US women of child-bearing age are taking medications contraindicated in pregnancy.

CONCLUSIONS

Given the benefits of optimized BP during pregnancy, this study highlights the critical need to improve DASH adherence and guide prescribing among women of child-bearing age.

Fruit and vegetable consumption is associated with lower prevalence of asymptomatic diverticulosis: a cross-sectional colonoscopy-based study

Background

Previous studies of the relationship between dietary factors and risk of diverticulosis have yielded inconsistent results. We therefore sought to investigate the association between consumption of fruit and vegetables and prevalent diverticulosis.

Methods

Our study population included participants in the Gastrointestinal Disease and Endoscopy Registry (GIDER), a colonoscopy-based longitudinal cohort at the Massachusetts General Hospital, who provided comprehensive information on dietary intake and lifestyle factors using validated questionnaires prior to colonoscopy. Information on presence and location of diverticula was obtained from the endoscopist at the end of each procedure. We used Poisson regression modeling to calculate the prevalence ratios (PRs) and 95% confidence intervals (CIs).

Results

Among 549 participants with a mean age of 61 years enrolled in GIDER, we confirmed diverticulosis in 245 (44.6%). The prevalence of diverticulosis appeared to decrease with higher consumption of fruit and vegetables (P_trend = 0.007 for fruit and 0.008 for vegetables, respectively). Compared to participants with less than five servings of vegetables per week, the multivariable-adjusted PRs of diverticulosis were 0.84 (95% CI, 0.60–1.17) with five to seven servings per week and 0.62 (95% CI, 0.44–0.89) with greater than one serving per day. Similarly, compared to participants with less than five servings per week of fruit, the multivariable-adjusted PR of diverticulosis was 0.60 (95% CI, 0.41–0.87) with greater than one serving per day. These associations were not modified by age, BMI, smoking, or red meat intake (All P_interaction > 0.055).

Conclusion

In a colonoscopy-based longitudinal cohort study, we show that higher consumption of fruit and vegetables is associated with lower risk of prevalent diverticulosis.

Cancer risk in microscopic colitis: a retrospective cohort study

Background

The long-term natural history of microscopic colitis (MC) (collagenous colitis (CC), lymphocytic colitis (LC)), traditionally considered relapsing but non-progressive diseases, is poorly defined. Whether persistent histologic inflammation in such diseases is associated with an increased risk of colorectal neoplasia (CRN) or extracolonic cancers has not been robustly established.

Methods

This retrospective cohort included diagnosed with MC at a referral center. Rates of CRN and extracolonic cancer were compared to patients undergoing screening colonoscopy (n = 306) and to the United States population using data from the Surveillance, Epidemiology, and End-Results (SEER) program. Standardized incidence ratios (SIR) and 95% confidence intervals were calculated and multivariable regression models used to identify the effect of MC diagnosis and severity on cancer risk.

Results

Our study included 221 patients with microscopic colitis (112 CC, 109 LC) among whom 77% were women. Compared to the colonoscopy control population, MC was associated with similar odds of tubular adenoma (Odds ratio (OR) 1.07, 95% CI 0.69–1.66) or villous adenoma (OR 1.26, 95% CI 0.17–9.42). Compared to patients with a single episode of MC, those with 2 or more episodes had similar risk of colon cancer (OR 0.83, 95% CI 0.20–3.39) or tubular adenoma (OR 1.49 95% CI 0.83–2.67). We also identified no statistical increase in the rates of cancer in the MC population compared to US-SEER data.

Conclusion

Microscopic colitis was not associated with increased risk of CRN and extracolonic cancers when compared to controls undergoing colonoscopy or the US SEER population.
