Abstract
AIM To investigate the impacts of breast conservation therapy (BCT) and mastectomy on heart-specific mortality in breast cancer patients. METHODS Patients with primary breast cancer registered in the Surveillance, Epidemiology, and End Results (SEER) database between Jan 1998 and Dec 2015 were included. Patients were divided into either breast conservation therapy or mastectomy group. To compare mortality caused by heart diseases in breast cancer patients with BCT or mastectomy, univariate and multivariate regression after propensity score matching (PSM) were performed. Kaplan-Meier analysis was also used to evaluate heart-specific survival between two groups. RESULTS 132,616 patients with breast cancer were enrolled in this study. After PSM, four risk factors including age, race, marital status and types of surgery were identified significantly associated with death from heart diseases. Heart-specific survival analysis further showed that overall, BCT poses a lower risk to heart-specific mortality compared with mastectomy. CONCLUSION Compared with mastectomy, BCT significantly decreased heart-specific mortality in breast cancer patients.

Elevation of Serum Copper in the New Orleans Bariatric Clinic Population: the Norm or Geographically Localized Findings? Obes Surg 2021; 31:4911-4917. [PMID: 34405337 DOI: 10.1007/s11695-021-05666-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 08/11/2021] [Accepted: 08/11/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION Circulating micronutrient levels of both serum copper and zinc have been studied to varying degrees in both the general public and patients having undergone bariatric surgery. According to the 2019 ASMBS clinical guidelines, copper supplementation is recommended for patients undergoing metabolic surgery, especially after Roux-en-Y gastric bypass and duodenal switch. Copper excess has not been previously reported to any significant degree in any population. OBJECTIVE In this study, we investigate an elevated serum copper level in the pre-surgical intervention population of the Bariatric Center of the University Medical Center-New Orleans, a primary safety net hospital for the state of Louisiana. METHODS Five hundred five consecutive patients from the bariatric surgery undergoing a workup for surgical intervention were assessed. Patients were included regardless of whether they proceeded to surgery. The study was conducted as a retrospective review of deidentified data that was collected as part of our routine workup for bariatric surgery. RESULTS The study population of the clinic consisted of a mean BMI of approximately 50 kg/m2, with 91% of the population reporting female and 69% recording an African American race. It was discovered in this population that 26% of the patients had an elevated copper level of > 155 mcg/dl. Additional analysis was performed attempting to elucidate an environmental role in the elevation by qualitative analysis of patient's location of residence using reported home address. Additional variables were studied as well including serum zinc concentration, age, BMI, and race to address any correlative variables with our findings. CONCLUSION This study identifies an elevated serum copper concentration in a pre-intervention underserved bariatric center population positively associated with BMI, female gender, and African American race. Additional studies will be necessary to see if these trends are also apparent in normal weight controls, or if weight loss influences copper levels. Pre-existing serum copper deficiencies may be more prevalent in the bariatric populations than previously believed. Increased serum copper in this population was positively associated with increased BMI, age, and female gender compared to that of the male group. Increased serum copper was also associated more closely with African American ethnicity compared to Caucasian patients.

Abstract
Obesity is a global epidemic that poses a serious health concern due to it being a risk factor for life-threatening chronic diseases, such as type 2 diabetes, cancer, and cardiovascular diseases. Pharmacotherapy remains the mainstay for the management of obesity; however, its usefulness is limited due to poor drug efficacy, non-specificity and toxic side effects. Therefore, novel approaches that could provide insights into obesity and obesity-associated diseases as well as development of novel anti-obesity treatment modalities or improvement on the existing drugs are necessary. While the ideal treatment of obesity should involve early intervention in susceptible individuals, targeted nanotherapy potentially provides a fresh perspective that might be better than the current conventional therapies. Independent studies have shown improved drug efficacy by using prohibitin (PHB)-targeted therapy in obese rodents and non-human primates, thus providing a proof of concept that targeted nanotherapy can be a feasible treatment for obesity. This review presents a brief global survey of obesity, its impact on human health, its current treatment and their limitations, and the role of angiogenesis and PHB in the development of obesity. Finally, the role and potential use of nanotechnology coupled with targeted drug delivery in the treatment of obesity are discussed.

Abstract
PURPOSE A concept analysis was undertaken to examine the attributes, characteristics, and uses of the concept of obesogenic environment within a pediatric context. CONCLUSIONS Utilizing a modified version of Walker and Avant's method, the attributes and characteristics of obesogenic environment were identified as it pertains to children. Based on the review of the literature and previous definitions applied to adults, a definition of the concept of obesogenic environment within a pediatric context was developed; examples of sample cases illustrate the concept further. PRACTICE IMPLICATIONS Defining the concept of obesogenic environment has utility for nursing theory development, practice, research, and education.

Abstract
The importance of changing patterns of obesity in society and its implications for public health are well recognized. However, the adult life course of body mass index (BMI) changes in individuals over time is largely unknown and has mostly been extrapolated from cross-sectional studies. The present study examines individual specific variation of BMI during a 15-year follow-up period in a community-based sample of UK females. We attempted to establish whether there is a common, generalized pattern which captures variation in BMI over time. The participants of this study belong to a prospective population cohort of British women studied intensively since 1989: the Chingford Study. The sample originally consisted of 1,003 women aged 45-68 years, who were assessed annually for BMI during follow-up period. Polynomial regression models were used to assess longitudinal BMI variation. We observed a great stability in individual BMI variation during the follow-up period, reflected by high correlations between the baseline BMI and follow-up BMI 10 and 15 years later (r = 0.876, N = 810, and r = 0.824, N = 638, respectively). We also found that three different major age-related patterns in BMI could be clearly identified: no change in 30.6% in 58% it increased and in 11.4% it decreased with age. Thus, our data suggest that individual age-related changes in BMI are very different. Therefore, simply combining all individuals into groups by any other criteria (age, sex, etc.) and overlooking the distinctive patterns of BMI change may lead to biased inferences in epidemiologic and etiologic research of the future.

Abstract
Obesity has become an international public health concern. In the United States, the rates of overweight and obesity have escalated dramatically in the last several decades. The health implications of obesity stem from its relationship with the development and progression of several health complications and diseases. Cardiovascular disease, which is the number one killer of women and men, is strongly influenced by obesity. The exact biological relationship between these two conditions is difficult to understand because several overlapping physiological systems and processes influence their development. One important component that affects obesity and cardiovascular disease is the sex of the individual. Although this basic biological variable is an obvious area for scientific study, research analyzing the influence of sex on obesity and cardiovascular disease is gravely lacking. The Society for Women's Health Research convened a workshop of obesity and cardiovascular disease experts in November 2005 to identify the gaps in scientific knowledge and crucial next steps in research related to sex differences in obesity and cardiovascular disease. This meeting report describes the workshop attendees' recommendations in detail.

Abstract
The prevalence of child and adolescent obesity has increased dramatically in the last 20 years and has led to a rise in cardiovascular-related comorbidities, including type 2 diabetes, in children and youth. The American Heart Association (AHA) issued a scientific statement with available evidence and guidance for health professionals involved in the prevention and management of childhood obesity. The scientific statement was ranked as 1 of the Top 10 Research Advances of 2005 by the AHA. This article builds on the scientific statement, presents multilevel determinants, and emphasizes individual and population-based approaches to prevention. Treatment of child and youth obesity, along with the implications for nurses and other health professionals, is also included.

Abstract
Obesity is associated with a number of serious diseases and with a degree of motor disability, but the extent of the risk and functional derangement within the obese population is not yet completely defined. The study aims to evaluate the combined effect of degree of adiposity, body fat distribution and age on selected cardiovascular risk factors and functional motor disability in a cohort of obese women. A multivariate analysis of variance (MANOVA) is employed to show the combined impact of body mass index (BMI), waist-to-hip ratio (WHR) and age on systolic and diastolic blood pressure (SBP and DBP), total and HDL cholesterol (T-CH and HDL-CH), coronary heart disease (CHD) risk, leg power output (W, assessed with a Margaria test for stair climbing) and subjective general fatigue in a cohort of 463 obese women (BMI range 30.2-66.7 kg/m2; age range 18-83 yr). High WHR and older age, but not BMI, are to a variable degree related to unfavorable values of parameters which contribute to the cardiovascular risk. WHR in the high range is associated with significantly higher values of SBP (p<0.001), CHD risk scores (p<0.001) as well as lower levels of HDL-CH (p=0.01), while older age is significantly associated with higher SBP (p<0.001), T-CH (p<0.001) and CHD risk scores (p<0.001). A significant interaction between age and WHR was detected in the effect on DBP (p=0.01), the negative role of high WHR values being apparent in older women (age > or = 51 yr) but not in younger ones (age < 51 yr). Although not significantly related to CHD risk scores, BMI interacted significantly with WHR in determining high risk score values (p=0.01), the negative effect of a high WHR being apparent in women with a high degree of obesity (BMI > or = 40 kg/m2) but not in those with a low one (BMI < 40 kg/m2). In contrast, WHR did not significantly affect W, which appeared to be mainly dependent on age (p<0.001) and BMI (p<0.001), when considered in terms of unit body mass (BM). Subjective global fatigue, however, was unaffected by any of the factors considered. In the present cohort of obese women, older age and excessive abdominal fat distribution (as assessed by WHR) appear to be significant factors in relation to increased cardiovascular disease risk, irrespective of BMI, while older age and higher levels of overall adiposity are associated with functional motor derangement irrespective of body fat distribution. This suggests that obesity increases metabolic risk and induces motor dysfunction by means of different biological mechanisms and with a different impact within the obese female population.

Abstract
OBJECTIVE Obesity, a major risk factor for idiopathic intracranial hypertension (IIH), is rapidly increasing in all ages of the United States population. We studied trends in the incidence of cerebrospinal fluid (CSF) shunts for IIH in the United States between 1988 and 2002, using a national hospital discharge database. METHODS This was a retrospective study using the Nationwide Inpatient Sample and robust weighted least-squares regression, adjusted for stratified survey methodology. RESULTS There were 2779 admissions for CSF shunting procedures (new or revision) in IIH patients in the database. In-hospital mortality for new shunts was 0.5% (0.9% for ventricular shunts and 0.2% for lumbar shunts). The estimated total United States caseload of CSF shunting procedures for IIH increased 350% between 1988 and 2002 (P < 0.001). (The 2002 United States caseload was 1370 admissions). New shunt placements increased 320% during this interval (P < 0.001). In some subpopulations in which obesity is less important as a risk factor for IIH, caseload increases were less marked: pediatric IIH shunting (age < 13 yr) increased 52% and shunting in male IIH patients increased 38%, but shunting in older patients (age > 44 yr) increased 240% during the study period. Bariatric procedures (e.g., gastric bypass) increased very rapidly in incidence since 1998, with nearly 200 such procedures performed on IIH patients in 2002. CONCLUSION The incidence of CSF shunting for IIH is increasing in the population of the United States at about the same relative rate as morbid obesity. Studies to establish the best shunting method in IIH and to explore alternative treatment strategies, such as optic nerve sheath fenestration and bariatric surgery, are urgently needed.
