Association between plausible genetic factors and weight loss from GLP1-RA and bariatric surgery: a multi-ancestry study in 10 960 individuals from 9 biobanks.

Obesity is a significant public health concern. GLP-1 receptor agonists (GLP1-RA), predominantly in use as a type 2 diabetes treatment, are a promising pharmacological approach for weight loss, while bariatric surgery (BS) remains a durable, but invasive, intervention. Despite observed heterogeneity in weight loss effects, the genetic effects on weight loss from GLP1-RA and BS have not been extensively explored in large sample sizes, and most studies have focused on differences in race and ethnicity, rather than genetic ancestry.

Breast Cancer Stage at Diagnosis in a Nigerian Hospital: Trend over a Decade.

Background: Breast cancer outcomes are poor in Nigeria, partly due to late-stage diagnosis. To assess the impact of past and present interventions, a review of an institutional data base was performed to determine the trend with respect to stage at diagnosis over a decade.

Methods: A retrospective analysis of an institutional data base was performed over a decade.

Breast cancer in elderly patients: a clinicopathological review of a Nigerian database.

Background: Breast cancer in the elderly population has not been evaluated in the Nigerian context. With the rising incidence of breast cancer and the changing demographics, it is likely that an increasing number of elderly patients will be managed in the coming years in Nigeria. This review describes the clinicopathological profile of elderly patients with breast cancer in a Nigerian database.

Contemporary management of breast cancer in Nigeria: Insights from an institutional database.

High-quality data are needed to guide interventions aimed at improving breast cancer outcomes in sub-Saharan Africa. We present data from an institutional breast cancer database to create a framework for cancer policy and development in Nigeria. An institutional database was queried for consecutive patients diagnosed with breast cancer between January 2010 and December 2018.

Habitual Fish Consumption, n-3 Fatty Acids, and Nuclear Magnetic Resonance Lipoprotein Subfractions in Women.

Background Supplementation with omega-3 (n-3) fatty acid or dietary fish may protect against atherosclerosis, but the potential mechanisms are unclear. Prior studies found modest triglyceride-lowering effects and slight increases in LDL (low-density lipoprotein) cholesterol. Limited evidence has examined n-3 effects on more detailed lipoprotein biomarkers.

Background: The use of mesh has revolutionized the management of hernias in many parts of the world. There is, however, limited experience on its use in sub-Saharan Africa. This study describes a single hospital experience after 500 cases of mesh hernia repairs in a sub-Saharan African country.

Group IIA Secretory Phospholipase A, Vascular Inflammation, and Incident Cardiovascular Disease.

Objective- Inflammation is a causal risk factor for cardiovascular disease (CVD). sPLA-IIA (group IIA secretory phospholipase A) plays an integral role in regulating vascular inflammation. Although studies investigated sPLA-IIA in secondary prevention, we prospectively evaluated sPLA-IIA mass and genetic variants with CVD events in a primary prevention population with chronic inflammation.

GlycA, a novel inflammatory marker, is associated with subclinical coronary disease.

Objective: GlycA, a novel NMR biomarker of inflammation, has been associated with incident cardiovascular disease (CVD) in the general population, but its association with CVD among HIV-infected individuals is unknown. We examined the associations between GlycA and subclinical coronary plaque among HIV-infected and HIV-uninfected men participating in Multicenter AIDS Cohort Study (MACS).

Design: Cross-sectional analysis of 935 men with plasma measurement of GlycA and noncontrast cardiac computed tomography (CT) and/or coronary CT angiography.

Associations of ideal cardiovascular health with GlycA, a novel inflammatory marker: The Multi-Ethnic Study of Atherosclerosis.

Background: Unhealthy lifestyles and inflammation contribute to cardiovascular disease (CVD). GlycA is a novel biomarker of systemic inflammation representing post-translational glycosylation of acute phase reactants and associated with increased clinical CVD risk.

Hypothesis: We hypothesized that ideal cardiovascular health (CVH), as assessed by (higher) Life's Simple 7 (LS7) scores, would be associated with lower GlycA levels among individuals free of CVD in a multiethnic community-based population.

Residual Risk of Atherosclerotic Cardiovascular Events in Relation to Reductions in Very-Low-Density Lipoproteins.

Background: It is uncertain whether pharmacological reductions in very-low-density lipoproteins (VLDLs), and their component triglyceride and cholesterol could reduce residual risk of atherosclerotic cardiovascular disease (ASCVD) events among individuals in whom low-density lipoprotein cholesterol (LDL-C) has been adequately lowered. We examined whether individuals with greater on-statin reductions in VLDL-related measures-beyond reductions in LDL-C-were at further reduced risk of ASCVD.

Methods And Results: In 9423 participants in the JUPITER (Justification for the Use of Statins in Prevention) trial (NCT00239681), at baseline and on statin we measured standard lipids, 400-MHz proton nuclear magnetic resonance spectroscopy-measured VLDL particle subclasses (small, medium, and large VLDL lipoprotein particle concentration), and total VLDL cholesterol mass.

Developing a Breast Cancer Screening Program in Nigeria: Evaluating Current Practices, Perceptions, and Possible Barriers.

Purpose: In low- and middle-income countries like Nigeria, women present with advanced breast cancer at an earlier age. Given the limited resources, development of screening programs that parallel resource capabilities of low- and middle-income countries is imperative. The objective of this study was to evaluate the perceptions, practices, and barriers regarding clinical breast examination (CBE) screening in a low-income community in Nigeria.

Atherogenic Lipoprotein Determinants of Cardiovascular Disease and Residual Risk Among Individuals With Low Low-Density Lipoprotein Cholesterol.

Background: Levels of LDL (low-density lipoprotein) cholesterol in the population are declining, and increasing attention is being focused on residual lipid-related pathways of atherosclerotic cardiovascular disease risk beyond LDL cholesterol. Among individuals with low (<130 mg/dL) LDL cholesterol, we undertook detailed profiling of circulating atherogenic lipoproteins in relation to incident cardiovascular disease in 2 populations.

Methods And Results: We performed proton nuclear magnetic resonance spectroscopy to quantify concentrations of LDL and VLDL (very low-density lipoprotein) particle subclasses in 11 984 JUPITER trial participants (NCT00239681).

Lipoprotein insulin resistance score and risk of incident diabetes during extended follow-up of 20 years: The Women's Health Study.

Background: Type II diabetes (T2D) is preceded by prolonged insulin resistance and relative insulin deficiency incompletely captured by glucose metabolism parameters, high-density lipoprotein (HDL) cholesterol and triglycerides.

Objective: Whether lipoprotein insulin resistance (LPIR) score, a metabolomic marker, is associated with incident diabetes and improves risk reclassification over traditional markers on extended follow-up.

Methods: Among 25,925 nondiabetic women aged 45 years or older, LPIR was measured by nuclear magnetic resonance spectroscopy as a weighted score of very low density lipoprotein, low-density lipoprotein, and HDL particle sizes, and their subsets concentrations.

Markers of Inflammation and Incident Breast Cancer Risk in the Women's Health Study.

Chronic inflammation may be a risk factor for the development and progression of breast cancer, yet it is unknown which inflammatory biomarkers and pathways are especially relevant. The present study included 27,071 participants (mean age = 54.5 years) in the Women's Health Study who were free of cancer and cardiovascular disease at enrollment (1992-1995), with baseline measures of 4 inflammatory biomarkers: high-sensitivity C-reactive protein, fibrinogen, N-acetyl side-chains of acute phase proteins, and soluble intercellular adhesion molecule-1.

Associations of Diabetes and Obesity with Risk of Abdominal Aortic Aneurysm in Men.

The associations of diabetes and obesity with the risk of abdominal aortic aneurysm (AAA) are inconclusive in previous studies. We conducted prospective analysis in the Physicians' Health Study. Among 25,554 male physicians aged ≥ 50 years who reported no AAA at baseline, 471 reported a newly diagnosed AAA during a mean of 10.

Effects of statins on the immunoglobulin G glycome.

Background: Statins are among the most widely prescribed medications worldwide and usually many individuals involved in clinical and population studies are on statin therapy. Immunoglobulin G (IgG) glycosylation has been associated with numerous cardiometabolic risk factors.

Methods: The aim of this study was to investigate the possible association of statin use with N-glycosylation of IgG.

Discordance between Circulating Atherogenic Cholesterol Mass and Lipoprotein Particle Concentration in Relation to Future Coronary Events in Women.

Background: It is uncertain whether measurement of circulating total atherogenic lipoprotein particle cholesterol mass [non-HDL cholesterol (nonHDLc)] or particle concentration [apolipoprotein B (apo B) and LDL particle concentration (LDLp)] more accurately reflects risk of incident coronary heart disease (CHD). We evaluated CHD risk among women in whom these markers where discordant.

Methods: Among 27533 initially healthy women in the Women's Health Study (NCT00000479), using residuals from linear regression models, we compared risk among women with higher or lower observed particle concentration relative to nonHDLc (highest and lowest residual quartiles, respectively) to individuals with agreement between markers (middle quartiles) using Cox proportional hazards models.

Association of N-Linked Glycoprotein Acetyls and Colorectal Cancer Incidence and Mortality.

Background: Acute phase proteins highlight the dynamic interaction between inflammation and oncogenesis. GlycA, a novel nuclear magnetic resonance (NMR) inflammatory marker that identifies primarily circulating N-acetyl glycan groups attached to acute phase proteins, may be a future CRC risk biomarker.

Methods: We examined the association between GlycA and incident CRC and mortality in two prospective cohorts (N = 34,320); Discovery cohort: 27,495 participants from Women's Health Study (WHS); Replication cohort: 6,784 participants from Multi-Ethnic Study of Atherosclerosis (MESA).

Breast cancer patients' presentation for oncological treatment: a single centre study.

Introduction: Breast cancer patients are presenting at advanced stages for oncological treatment in Nigeria and World Health Organization predicted developing countries' breast cancer incidence and mortality to increase by year 2020.

Methods: Prospective observational hospital based study that enrolled breast cancer patients from catchment area of an oncology service hospital in Nigeria between 2007 and 2013. Patients' demographics, breast cancer burden and health care giver presentation variables were analysed for causal factors of seeking medical help and what determines commencement of effective oncological treatment.

Circulating N-Linked Glycoprotein Side-Chain Biomarker, Rosuvastatin Therapy, and Incident Cardiovascular Disease: An Analysis From the JUPITER Trial.

Background: GlycA, a novel protein glycan biomarker of N-acetyl side chains of acute-phase proteins, was recently associated with incident cardiovascular disease (CVD) in healthy women. Whether GlycA predicts CVD events in the setting of statin therapy in men and women without CVD but with evidence of chronic inflammation is unknown.

Methods And Results: In the Justfication for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER) trial (NCT00239681), participants with low-density lipoprotein cholesterol <130 mg/dL and high-sensitivity C-reactive protein (hsCRP) ≥2 mg/L were randomized to rosuvastatin 20 mg/day or placebo.

Association of Lipoproteins, Insulin Resistance, and Rosuvastatin With Incident Type 2 Diabetes Mellitus : Secondary Analysis of a Randomized Clinical Trial.

Importance: Statins decrease levels of low-density lipoprotein (LDL) and triglycerides as well as cardiovascular events but increase the risk for a diagnosis of type 2 diabetes mellitus (T2DM). The risk factors associated with incident T2DM are incompletely characterized.

Objective: To investigate the association of lipoprotein subclasses and size and a novel lipoprotein insulin resistance (LPIR) score (a composite of 6 lipoprotein measures) with incident T2DM among individuals randomized to a high-intensity statin or placebo.

Circulating N-Linked Glycoprotein Acetyls and Longitudinal Mortality Risk.

Rationale: Circulating glycoprotein N-acetyl glucosamine residues have recently been associated with incident cardiovascular disease and diabetes mellitus.
