ABSTRACT
OBJECTIVE: To assess the relationship between knowledge of long-acting reversible contraception (LARC) and intention to use LARC among female students. PARTICIPANTS: Participants consisted of a convenience sample of 292 female undergraduate and graduate students at a large midwestern university. METHODS: We conducted a cross-sectional in-person survey and multivariate analysis of LARC knowledge and intention to use LARC. RESULTS: Total response rate was 84.9%. Among contraceptive users, 13.3% were using a LARC method. On average, respondents scored 4.8/10 (SD 2.5) on a 10-item LARC knowledge assessment. Higher levels of LARC knowledge were associated with the intent to use LARC in the future in our multivariate analysis (RR 1.7, 95% CI 1.14-2.54: p = .01). Common reasons for LARC hesitancy were a need for more information, safety concerns, and risk of undesirable side effects. CONCLUSIONS: Low LARC knowledge and students' self-identified need for further LARC information represent an opportunity for campus contraceptive interventions which empower students to make informed reproductive decisions.
ABSTRACT
Preeclampsia leads to increased risk of morbidity and mortality for both mother and fetus. Most previous studies have largely neglected mechanical compression of the left renal vein by the gravid uterus as a potential mechanism. In this study, we first used a murine model to investigate the pathophysiology of left renal vein constriction. The results indicate that prolonged renal vein stenosis after 14 days can cause renal necrosis and an increase in blood pressure (BP) of roughly 30 mmHg. The second part of this study aimed to automate a diagnostic tool, known as the supine pressor test (SPT), to enable pregnant women to assess their preeclampsia development risk. A positive SPT has been previously defined as an increase of at least 20 mmHg in diastolic BP when switching between left lateral recumbent and supine positions. The results from this study established a baseline BP increase between the two body positions in nonpregnant women and demonstrated the feasibility of an autonomous SPT in pregnant women. Our results demonstrate that there is a baseline increase in BP of roughly 10-14 mmHg and that pregnant women can autonomously perform the SPT. Overall, this work in both rodents and humans suggests that (1) stenosis of the left renal vein in mice leads to elevation in BP and acute renal failure, (2) nonpregnant women experience a baseline increase in BP when they shift from left lateral recumbent to supine position, and (3) the SPT can be automated and used autonomously.
ABSTRACT
OBJECTIVES: The goal of this study is to describe modifiable lifestyle variables associated with reduced rate of Parkinson's disease (PD) progression. METHODS: The patient-reported outcomes in PD (PRO-PD) were used as the primary outcome measure, and a food frequency questionnaire (FFQ) was used to assess dietary intake. In this cross-sectional analysis, regression analysis was performed on baseline data to identify the nutritional and pharmacological interventions associated with the rate of PD progression. All analyses were adjusted for age, gender, and years since diagnosis. RESULTS: 1053 individuals with self-reported idiopathic PD were available for analysis. Foods associated with the reduced rate of PD progression included fresh vegetables, fresh fruit, nuts and seeds, nonfried fish, olive oil, wine, coconut oil, fresh herbs, and spices (P < 0.05). Foods associated with more rapid PD progression include canned fruits and vegetables, diet and nondiet soda, fried foods, beef, ice cream, yogurt, and cheese (P < 0.05). Nutritional supplements coenzyme Q10 and fish oil were associated with reduced PD progression (P = 0.026 and P = 0.019, resp.), and iron supplementation was associated with faster progression (P = 0.022). DISCUSSION: These are the first data to provide evidence that targeted nutrition is associated with the rate of PD progression.
