Dyslipidemia is increasing among U.S. children, and the prevalence is highest among children with diabetes and obesity. Recently, vitamin D deficiency has been suggested as a possible dietary risk factor for dyslipidemia. Despite the high prevalence of vitamin D deficiency amongst children, virtually no studies have evaluated the association between vitamin D and dyslipidemia among children. We evaluated the vitamin D and dyslipidemia relationship among 240 children and adolescents aged 2 through 21 years who were outpatients of a pediatric endocrinology unit at a large tertiary care facility in Western Massachusetts from April 2008 to April 2010. Eligible children were those with either obesity and/or type 1 or 2 diabetes mellitus. A total of 17.4% of children had severe (<15.0 ng/ml) vitamin D deficiency, 19.2% had moderate (15.0-19.9 ng/ml) deficiency, 36.3% were insufficient (20.0-29.9 ng/ml), and 27.1% had normal (≥30.0 ng/ml) levels. A total of 28.8% of children had high total cholesterol (TC ≥180 mg/dL), 19.6% had high triglycerides (TG; <10years: ≥110 mg/dL, ≥10years: ≥130 mg/dL), 21.3% had low high density lipoprotein (HDL <40 mg/dL), and 6.7% had high low density lipoprotein (LDL ≥130 mg/dL). Moderate vitamin D deficiency was associated with increased risk of high TC (adjusted odds ratio [OR adj] = 2.9, 95% confidence interval (CI): 1.0, 8.8) compared to children with normal vitamin D levels. Severe vitamin D deficiency was associated with an increased risk of low HDL (OR adj = 3.5, 95% CI: 1.0-12.3) and high TG (OR adj = 11.7, 95% CI: 1.9, 70.3) compared to children with normal vitamin D levels. Children with moderate vitamin D deficiency had approximately 3-fold increased risk of high TC compared to children with normal vitamin D levels. In comparison to children with normal vitamin D levels, severe vitamin D deficiency was associated with a strong and significant increased risk of low HDL and high TG; with a significant dose-response relationship. Additionally, in linear regression analyses, we found that an increase in vitamin D deficiency was associated with a significant mean increase in all four measures of dyslipidemia. Vitamin D adequacy may reduce the risk of dyslipidemia in children.

<p>Research examining the relationships between religious indicators and the cardiovascular health of individuals and populations has been relatively understudied in the Canadian context. This thesis contains three main studies, developed from a sequential explanatory mixed method research design.</p> <p>The first study examined the association between the frequency of religious service attendance (RSA) and prevalence of coronary heart disease (CHD), diabetes and high blood pressure in Canada. The Saskatchewan sample of the Canadian Community Health Survey (CCHS-4.1) was used to build multivariable logistic regression models. The analysis revealed participants who attended religious services more than once a week had lower prevalent odds of CHD (OR= 0.82, 95% CI 0.61-1.11, p>0.05), diabetes (OR=0.60, 95% CI 0.45-0.80, p</p> <p>The second study was qualitative and undertaken to help interpret and explain the quantitative results from the CCHS. Twelve semi-structured interviews with ordained pastors and three focus groups with parishioners in Catholic, Anglican and United churches were conducted in Canada. The findings suggest that attending religious services: (1) promotes mental health; (2) provides social support and activities; and (3) promotes health and lifestyle behaviours to lower CHD risk.</p> <p>Qualitative data from the second study was used for the third study, which identified relevant factors associated with the implementation of heart health promotion programs in churches. Among the various factors identified, pastor leadership, funding for a parish nurse, community-focused interventions, secured infrastructure and social support were important to facilitate health promotion programs in churches.</p> / Doctor of Philosophy (PhD)

As gerontologists may know, there are a great deal of studies and a variety of academic literature on the misuse of alcohol and prescription medication amongst the elderly population. While there is a plethora of information on alcohol and prescription misuse, there is little reported data about the prevalence of other substance misuse experienced by this population. This study aims to help to fill that gap in the data by using quantitative methods to describe the scope of substance abuse of individuals 55-years or older. This study utilizes data from the Treatment Data Set Admission (TEDS-A). The TEDS-A is a public data set which includes admissions data from multiple substance abuse treatment facilities associated with the Substance Abuse and Mental Health Services Association (SAMHSA). This is a regional study, therefore this study focuses only on individuals 55-years or older who have been admitted into substance abuse treatment facilities in the state of California in the year 2014. The TEDS-A is a data set that is supported and conducted by members of SAMHSA. Most of their public data sets, including the TEDS-A, can be accessed on their website (https://www.datafiles.samhsa.gov/study/treatment-episode-data-set-admissions-teds-2014-nid16949). The data available in the TEDS-A involves a number of admission questions, including demographic data, reasons for intake, primary through tertiary substance concerns, questions regarding social status, information on medical insurance, and more. This study looks at the descriptive frequencies of the use of alcohol, crack/cocaine, marijuana/hashish, heroin, other opiates & synthetics, methamphetamine, and other substances. The study includes 13,512 cases, of which 9966 (73.8%) of cases were male, 3539 (26.2%) were female, and 7 (0.1%) were missing and/or invalid. The results of the data suggests that, while alcohol abuse is a problem, those over 55 are admitted into substance abuse clinics for many other reasons, not just alcohol abuse.

BackgroundThe prompt seeking of medical care after the onset of symptoms suggestive of acute coronary syndromes (ACS)/acute myocardial infarction (AMI) is associated with the receipt of coronary reperfusion therapy, and effective cardiac medications in patients with an ACS/AMI and is crucial to reducing mortality and the risk of serious clinical complications in these patients. Despite declines in important hospital complications and short-term death rates in patients hospitalized with an ACS/AMI, several patient groups remain at increased risk for these adverse outcomes, including women and the elderly. However, recent trends in age and sex differences in extent of pre-hospital delay, hospital management practices, and short-term outcomes associated with ACS/AMI remain unexplored. The objectives of this study were to examine the overall magnitude, and changing trends therein, of age and sex differences in duration of pre-hospital delay (1986-2005), hospital management practices (1999-2007), and short-terms outcomes (1975-2005) in patients hospitalized with ACS/AMI. MethodsData from 13,663 residents of the Worcester, MA, metropolitan area hospitalized at all greater Worcester medical centers for AMI 15 biennial periods between 1975 and 2005 (Worcester Heart Attack Study), and from 50,096 patients hospitalized with an ACS in 106 medical centers in 14 countries participating in the Global Registry of Acute Coronary Events (GRACE) between 2000 and 2007 were used for this investigation. Results In comparison with men years, patients in other age-sex strata exhibited significantly longer pre-hospital delay, with the exception of women < 65 years; had a significantly lower odds of receiving aspirin, angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), beta blockers, statins, and undergoing coronary artery bypass graft surgery (CABG) surgery or percutaneous coronary intervention (PCI), and were significantly more likely to develop atrial fibrillation, cardiogenic shock, heart failure, and to die during hospitalization and in the first 30 days after admission. There was a significant interaction between age and sex in relation to the use of several medications and the development of several of these outcomes; in patients Conclusions Our results suggest that the elderly were more likely to experience longer prehospital delay, were less likely to be treated with evidence-based treatments during hospitalization for acute coronary syndrome, and were more likely to develop adverse outcomes compared to younger persons. Younger women were less likely to be treated with effective treatments and were more likely to develop adverse outcomes compared with younger men while there was no sex difference in these outcomes. Interventions targeted at older patients, in particular, are needed to encourage these high-risk patients to seek medical care promptly to maximize the benefits of currently available treatment modalities. More targeted treatment approaches during hospitalization for ACS/AMI for younger women and older patients are needed to improve their hospital prognosis.

Osteoporosis is a significant public health problem in the U.S. It not only affects the physical well-being of the older women but also creates a substantial financial burden for the health care system. The mainstay of osteoporosis medications is bisphosphonate treatment of which alendronate and risedronate are the most commonly prescribed in clinical practice. However, there have been no head-to-head randomized controlled trials (RCTs) evaluating the effects of these two bisphosphonates on fracture outcomes. In the absence of RCTs, observational studies are necessary to provide alternative evidence on the comparative effectiveness between alendronate and risedronate on fracture outcomes. However, existing observational studies have provided inconclusive results partially due to residual confounding from unobserved variables such as patients’ health status or behavior. IV analysis may be one method to address unmeasured confounding bias in observational studies. While it has not been applied in bisphosphonate research, it has been used in research on a variety of other prescription medications. In this dissertation, we applied the IV approach with an IV, date of generic alendronate availability, to evaluate the comparative effectiveness between alendronate and risedronate using observational data. This dissertation improved current research in several ways. First, we extended the IV approach to research on bisphosphonates. Second, compared with the current observational studies on bisphosphonates, this dissertation may more accurately estimate the relative effects between alendronate and risedronate because IV analysis is not subject to unmeasured confounding bias. Third, the study results extended the current evidence of the comparative effectiveness between the two most commonly prescribed bisphosphonates. Finally, we proposed and provided empirical evidence of a new IV that might be used for future prescription drug research. The finding of this dissertation can be summarized from three aspects. First, we found that the evidence supported the validity of the date of generic availability as an IV in the study of bisphosphonates. Second, applying IV approach to study the comparative effectiveness of alendronate and risedronate, we found that alendronate and risedronate were comparable to reduce the risk of 12-month non-vertebral fractures in older women. Since generic alendronate is availability on the market while generic risedronate is not, promoting the use of alendronate may help reduce the healthcare cost and not sacrifice the clinical effectiveness. Finally, by comparing the proposed IV with a popular IV-physician preference, we found that both the calendar time IV based on the date of generic availability and the physician preference appeared to be valid. It might be practically easier to use the calendar time IV than the physician preference IV.

Limited data exists describing the long-term prognosis of patients with acute decompensated heart failure (ADHF) further stratified according to currently recommended ejection fraction (EF) findings. In addition, little is known about the magnitude of, and factors associated with, long-term prognosis for these patients. Based on previously validated and clinically relevant criteria, we defined HF-REF as patients with an EF value ≤40%, HF-PEF was defined as an EF value > 50%, and HF-BREF was defined as patients with an EF value during their index hospitalization between 41 and 49%. The hospital medical records of residents of the Worcester (MA) metropolitan area who were discharged after ADHF from all 11 medical centers in central Massachusetts during the 5 study years of 1995, 2000, 2002, 2004, and 2006 were reviewed. Follow-up was completed through 2011 for all patient cohorts. The average age of this population was 75 years, the majority was white, and 44% were men. Patients with HF-PEF experienced higher post discharge survival rates than patients with either HF-REF or HF-BREF at 1, 2, and 5-years after discharge. Advanced age and lower estimated glomerular filtration rate findings at the time of hospital admission were important predictors of 1-year death rates, irrespective of EF findings. Previously diagnosed chronic obstructive pulmonary disease, chronic kidney disease, and atrial fibrillation were associated with a poor prognosis in patients with PEF and REF whereas a history of diabetes was an important prognostic factor for patients with REF and BREF. In conclusion, although improvements in 1-year post-discharge survival were observed for patients in each of the 3 EF groups examined to varying degrees, the post- 7 discharge prognosis of all patients with ADHF remains guarded. In addition, we observed differences in several prognostic factors between patients with ADHF with varying EF findings, which have implications for more refined treatment and surveillance plans for these patients.

Current research shows moderate alcohol consumption is associated with decreased risk of diabetes and excessive consumption or binge drinking can cause insulin resistance and diabetes. In 2010, diabetes was the seventh leading cause of death in the United Statesand was responsible for significant health complications: blindness, kidney failure, and limb amputations, and is a large national economic burden. Fasting blood glucose (FBG) is a tool used to help diagnose diabetes. Abnormally high FBG, ≥100 mg/dl, is indicative of diabetes and pre-diabetes. Few studies have observed diabetic prevalence among young adults or college students. Studying young adults can help provide added information about early risk factors for diabetes and pre-diabetes, facilitating public health efforts to stem the rising tide of the diabetes epidemic. This study aimed to research the associations between alcohol consumption (numbers of days alcohol consumed in the past month and binge alcohol consumption in the past month) and FBG in a college population as part of the FLASH cohort study. FBG levels were measured in 141 young adult participants and alcohol consumption was determined by self report. Other individual-level characteristics and potential confounding variables were also collected. The association between alcohol consumption and FBG followed a J-shaped curve whereby students who reported drinking 6-8 days within the last 30 days showed significantly lower FBG levels than those who did not drink and those who consumed alcohol on nine or more days (p=0.04). Binge drinking did not have a significant association with FBG (p=0.4). Sex and body mass index were also significantly associated with FBG. In conclusion, moderate frequency of alcohol consumption is found to have an inverse relationship with FBG and excessive drinking can reverse these effects.

The obesity epidemic is widespread in American society, often affecting children who bear its consequences innocently. Due to a lack of nutrition knowledge, children rely on caregivers to meet their nutritional needs and instill healthy habits. This study examines parents' attitudes, knowledge, and behaviors, as well as perceived barriers to adopting a whole-foods plant-based diet (WFPD) for their children. Using a modified survey instrument by Morton et al., this study focused on parents and children regarding dietary choices. Participants were recruited from the waiting area of a pediatric clinic at the Medical College of Georgia between April and May 2023. They completed paper surveys assessing beliefs about whole-foods plant-based diet knowledge and suitability, and identifying barriers to adoption. Among the 48 participants, with children averaging 7.5 years old, 69% were familiar with WFPD health benefits, and 17% had past or current involvement with a whole-foods plant-based diet. Likert scale scores determined confidence intervals for opinions on whole-foods plant-based diet barriers, adoption, and nutritional knowledge. Kendall’s tau-b correlation tests uncovered significant connections between perceived barriers, demographics, and understanding of whole-foods plant-based diets. A Spearman’s rank-order test found no correlation between a parent's assessment of their child's health and whole-foods plant-based diet engagement. Many parents didn't perceive significant hurdles to WFPD adoption and expressed readiness to embrace its benefits for their children, pending guidance from healthcare professionals and assistance with shopping and meal preparation. Openings toward solutions to the childhood obesity epidemic exist if stakeholders would reach out and take advantage of the most impactful methods of educating the public in terms of the benefits and successes of a whole-foods plant-based diet.

Introduction: Central Line-Associated Bloodstream Infections (CLABSIs) are a major cause of increased mortality, morbidity and healthcare costs in neonatal intensive care units (NICUs) patients. Despite CDC's efforts to reduce infection rates, patients often suffer consequences. The objective of this study is to perform a systematic review of strategies utilized in the neonatal population and evaluate them with the current CDC's guidelines to assess the effectiveness of bundles in preventing CLABSI in NICUs. Methods: A systematic literature search was conducted using CINAHL Plus with Text, Cochrane Database of Systematic Reviews and MEDLINE from January 2008 up to 2018. There were multiple search terms used and these included "neonate OR newborn OR infant", "CLABSI OR central line-associated bloodstream infection", "intervention OR prevention" and "bundle". The search solely focused on the outcome of infant patients. Therefore studies were excluded for the following criteria: being non-peer reviewed, being published before 2008, and being a case in which CLABSI was assessed in patients outside the NICU. See Table 4 and 5 for further information. Results: Eight articles were eligible for inclusion all of which CDC's guidelines were implemented in their strategy of intervention. The systematic review showed that adherence to care bundles decreases infection rates drastically. All eight articles reported a significant decrease in CLABSI rates following the implementation of the bundle set by CDC with two studies achieving a CLABSI rate of zero. Author's Conclusion: Implementation of care bundles showed a success in reducing CLABSI rates in the NICUs; however none of the studies endorsed a specific bundle application utilized to achieve its intended goal. Some practices adopted CDC's guidelines more than others and those showed a greater decrease in infection rate. In addition, it is evident that nurses deliver the best care when preventing an infection. Further research is needed to assess the effectiveness of a specific bundle element.
