Change the World One Worm at a Time!
My Capstone Project aims to blend the old with the new. It\u27s about taking tried-and-true farming practices and breathing new life into them with innovative, sustainable solutions. It seeks to balance making a living from the land and caring for it for future generations.
The project\u27s core revolves around Organic Worm Tea, a natural product we\u27ve been developing and testing. This process involves rolling up our sleeves, getting our hands dirty, and observing the tea\u27s effect on various farms, including those run by immigrant farmers who bring unique farming traditions from their home countries.
But this project isn\u27t just about my local farming community; it\u27s also about the bigger picture. My project aims to inspire more farmers to adopt these practices by showing that sustainable farming can pay the bills. Ultimately, this could trigger a ripple effect, transforming the world of agriculture into one that\u27s healthier and more sustainable

A Systematic Examination of the 2013Ā ACC/AHA Pooled Cohort RiskĀ Assessment Tool for AtheroscleroticĀ Cardiovascular Disease
AbstractBackgroundThe 2013 American College of Cardiology/American Heart Association updated cholesterol guidelines recommend the use of Pooled Cohort Equations to estimate 10-year absolute risk for atherosclerotic cardiovascular disease (ASCVD) in primary prevention.ObjectivesThis study sought to systematically examine the Pooled Cohort Equations to determine risk factor levels required to exceed risk thresholds outlined in new cholesterol guidelines.MethodsWe entered continuous risk factor levels in isolation and in specified combinations with the risk tool, and we observed predicted risk output patterns. We used the 10-year ASCVD risk threshold ofĀ ā„7.5% as a clinically relevant risk threshold.ResultsWe demonstrated that a hypothetical man or woman can reach clinically relevant risk thresholds throughout the eligible age spectrum of 40 to 79 years of age, depending on the associated risk factor burden in all race-sex groups. Age continues to be a major determinant of 10-year ASCVD risk for both men and women. Compared with the previous risk assessment tool used in cholesterol guidelines, the inclusion of a stroke endpoint and use of race-specific coefficients permit identification of at-risk African Americans and non-Hispanic white women at much younger ages and lower risk factor levels.ConclusionsThese data provide context of specific risk factor levels and groups of individuals who are likely to have 10-year ASCVD risk estimatesĀ ā„7.5%. Age continues to be a major driver of risk, which highlights the importance of the clinician-patient discussion before statin therapy is initiated
High-Density Lipoprotein Cholesterol and Particle Concentrations, Carotid Atherosclerosis, and Coronary Events MESA (Multi-Ethnic Study of Atherosclerosis)
ObjectivesThe purpose of this study was to evaluate independent associations of high-density lipoprotein cholesterol (HDL-C) and particle (HDL-P) concentrations with carotid intima-media thickness (cIMT) and incident coronary heart disease (CHD).BackgroundHDL-C is inversely related to CHD, and also to triglycerides, low-density lipoprotein particles (LDL-P), and related metabolic risk. HDL-P associations with CHD may be partially independent of these factors.MethodsIn a multiethnic study of 5,598 men and women ages 45 to 84 years old, without baseline CHD, excluding subjects on lipid-lowering medications, triglycerides >400 mg/dl, or missing values, we evaluated associations of HDL-C and nuclear magnetic resonance spectroscopy-measured HDL-P with cIMT and incident CHD (myocardial infarction, CHD death, and angina, n = 227 events; mean 6.0 years follow-up). All models were adjusted for age, sex, ethnicity, hypertension, and smoking.ResultsHDL-C and HDL-P correlated with each other (Ļ = 0.69) and LDL-P (Ļ = ā0.38, ā0.25, respectively, p < 0.05 for all). For (1 SD) higher HDL-C (15 mg/dl) or HDL-P (6.64 Ī¼mol/l), cIMT differences were ā 26.1 (95% confidence interval [CI]: ā34.7 to ā17.4) Ī¼m and ā30.1 (95% CI: ā38.8 to ā 21.4) Ī¼m, and CHD hazard ratios were 0.74 (95% CI: 0.63 to 0.88) and 0.70 (95% CI: 0.59 to 0.82), respectively. Adjusted for each other and LDL-P, HDL-C was no longer associated with cIMT (2.3; 95% CI: ā 9.5 to 14.2 Ī¼m) or CHD (0.97; 95% CI: 0.77 to 1.22), but HDL-P remained independently associated with cIMT (ā22.2; 95% CI: ā 33.8 to ā10.6 Ī¼m) and CHD (0.75; 95% CI: 0.61 to 0.93). Interactions by sex, ethnicity, diabetes, and high-sensitivity C-reactive protein were not significant.ConclusionsAdjusting for each other and LDL-P substantially attenuated associations of HDL-C, but not HDL-P, with cIMT and CHD. Potential confounding by related lipids or lipoproteins should be carefully considered when evaluating HDL-related risk
The bactericidal effect of shock waves
There are a variety of theories relating to the origins of life on our home planet, some of which
discuss the possibility that life may have been spread via inter-planetary bodies. There have been a number
of investigations into the ability of life to withstand the likely conditions generated by asteroid impact (both
contained in the impactor and buried beneath the planet surface). Previously published data regarding the
ability of bacteria to survive such applied shockwaves has produced conflicting conclusions. The work
presented here used an established and published technique in combination with a single stage gas gun,
to shock and subsequently recover Escherichia coli populations suspended in a phosphate buffered saline
solution. Peak pressure across the sample region was calculated via numerical modelling. Survival data
against peak sample pressure for recovered samples is presented alongside control tests. SEM micrographs
of shocked samples are presented alongside control sets to highlight key differences between cells in each
case
Estimating the workload associated with symptoms-based ovarian cancer screening in primary care: an audit of electronic medical records
BACKGROUND: Ovarian cancer is the most lethal gynaecological malignancy in the United Kingdom (UK). Studies have found that many women with ovarian cancer have symptoms for several months before diagnosis. Using a symptoms-based tool to diagnose ovarian cancer (OC) earlier is appealing, but may increase general practitioner (GP) workload because the symptoms are typically vague and non-specific. This study aimed to provide estimates of the GP workload associated with offering symptoms-based ovarian cancer screening. METHODS: A cross-sectional analysis of electronic records from four general practices in England, UK. We downloaded anonymous data on women aged 45ā74 who consulted over one week to estimate the proportion who would be offered āscreeningā according to the UK National Institute for Health and Care Excellence (NICE) guidelines and a symptoms index (Index 2) over one year. We used previous consultations (censoring women with no prior symptom at the date of their last recorded consultation) to estimate the proportion of women presenting with a new (not recorded in previous 12Ā months) NICE symptom each year. RESULTS: Data were obtained from 19,558 women. The proportion presenting over one week varied between practices (5%-14%), however, the proportion with an OC symptom was similar (17% overall). Over one year, an estimated 51.8% (95% CI 44.0%-59.7%) would present with an OC symptom, 26.6% (95% CI 19.3%-35.1%) with a NICE symptom and 20.3% (95% CI 13.7%-28.5%) with an Index 2 symptom. Each year, an estimated 11.9% (95% CI 5.0%-18.3%) of women would present with a new NICE symptom. CONCLUSION: One in two women aged 45ā74 present to primary care at least once a year with an OC symptom, 11.9% with a new NICE symptom. This would be comparable to 2 to 8 yearly screening (depending on what symptoms triggered testing)
