Abstract
The apolipoprotein-E4 (APOE*4) and apolipoprotein-E2 (APOE*2) alleles are more common in African American versus non-Hispanic white populations, but relationships of both alleles with Alzheimer's disease (AD) pathology among African American individuals are unclear. We measured APOE allele and β-amyloid (Aβ) and tau using blood samples and positron emission tomography (PET) images, respectively. Individual regression models tested associations of each APOE allele with Aβ or tau PET overall, stratified by racialized group, and with a racialized group interaction. We included 358 older adults (42% African American) with Aβ PET, 134 (29% African American) of whom had tau PET. APOE*4 was associated with higher Aβ in non-Hispanic white (P < 0.0001), but not African American (P = 0.64) participants; racialized group modified the association between APOE*4 and Aβ (P < 0.0001). There were no other racialized group differences. These results suggest that the association of APOE*4 and Aβ differs between African American and non-Hispanic white populations. Other drivers of AD pathology in African American populations should be identified as potential therapeutic targets.

Abstract
Background Statins are a cost-effective therapy for prevention of atherosclerotic cardiovascular disease (ASCVD). Guidelines on statins for primary prevention are unclear for older adults (>75 years). Objective Investigate statin utility in older adults without ASCVD events, by risk stratifying in a large healthcare network. Methods We included 8,114 older adults, without CAD, PVD or ischemic stroke. Statin utilization based on ACC/AHA 10-year ASCVD risk calculation, was evaluated in intermediate (7.5%-19.9%) and high-risk patients (≥ 20%); and categorized using low and 'moderate or high' intensity statins with a follow up period of ∼7 years. Cox regression models were used to calculate hazard ratios for incident ASCVD and mortality across risk categories stratified by statin utilization. Data was adjusted for competing risk using Elixhauser Comorbidity Index. Results Compared with those on moderate or high intensity statins, high-risk older patients not on any statin had a significantly increased risk of MI [HR 1.51 (1.17-1.95); p<0.01], stroke [HR 1.47 (1.14-1.90); p<0.01] and all-cause mortality [HR 1.37 (1.19-1.58); p<0.001] in models adjusted for Elixhauser Comorbidity Index. When comparing the no statin group versus the moderate or high intensity statin group in the intermediate risk cohort, although a trend for increased risk was seen, it did not meet statistical significance thresholds for MI, stroke or all-cause mortality. Conclusion Lack of statin use was associated with increased cardiovascular events and mortality in high-risk older adults. Given the benefits appreciated, statin use may need to be strongly considered for primary ASCVD prevention among high-risk older adults. Future studies will assess the risk-benefit ratio of statin intervention in older adults.

Abstract
BACKGROUND Trastuzumab deruxtecan (T-DXd) has shown promising results in patients with breast cancer brain metastases (BCBMs). We conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of T-DXd in the human epidermal growth factor receptor 2 (HER2)-positive BCBM population. PATIENTS AND METHODS We searched PubMed, Embase, and Cochrane Library databases as well as American Society of Clinical Oncology (ASCO), European Society for Medical Oncology (ESMO), and San Antonio Breast Cancer Symposium (SABCS) websites for clinical trials (CTs) and observational studies evaluating T-DXd in patients with HER2-positive BCBM. Heterogeneity was assessed with I2 statistics. Random effects models were used for all statistical analyses, which were carried out using R software (version 4.2.2). RESULTS Ten studies were included, six CTs (n = 189) and four observational studies (n = 130), with a total of 319 patients. The median progression-free survival was 15 months [95% confidence interval (CI) 13.9-16.1 months]. The objective response rate (ORR) was 61% (95% CI 52% to 70%), and the intracranial (IC)-ORR was 61% (95% CI 54% to 69%). No significant differences in ORR and IC-ORR were observed between CTs and observational studies (P = 0.31 and 0.58, respectively). The clinical benefit rate (CBR) was 80% (95% CI 52% to 94%), and the IC-CBR was 70% (95% CI 54% to 82%). The ORR was 68% (95% CI 57% to 77%) in the subgroup of patients with stable BMs and 60% (95% CI 48%-72%) in patients with active BM, with no significant difference between groups (P = 0.35). CONCLUSIONS Our systematic review and meta-analysis supports the IC activity of T-DXd in patients with stable BM and active BM. TRIAL REGISTRATION International Prospective Register of Systematic Reviews (PROSPERO) under the protocol number CRD42023422589.

Abstract
Background In the US, women have similar cardiovascular death rates than men. Less is known about sex differences in statin use for primary prevention and associated atherosclerotic cardiovascular disease (ASCVD) outcomes. Methods Statin prescriptions using electronic health records were examined in patients without ASCVD (myocardial infarction (MI), revascularization or ischemic stroke) between 2013-2019. Guideline-directed statin intensity (GDSI) at index and follow-up visits were compared among sexes across ASCVD risk groups, defined by pooled-cohort equation. Cox regression hazard ratios (HR) [95% CI] were calculated for statin use and outcomes (myocardial infarction, stroke/transient ischemic attack (TIA), and all-cause mortality) stratified by sex. Interaction terms (statin and sex) were applied. Results Among 282,298 patients, (mean age ∼ 50 years) 17.1% women and 19.5% men were prescribed any statin at index visit. Time to GDSI was similar between sexes, but the proportion of high-risk women on GDSI at follow-ups was lower compared to high-risk men (2-years: 27.7 vs 32.0%, and 5-years: 47.2 vs 55.2%, p<0.05). When compared to GDSI, no statin use was associated with higher risk of MI and ischemic stroke/TIA amongst both sexes. High-risk women on GDSI had a lower risk of mortality (HR=1.39 [1.22-1.59]) versus men (HR=1.67 [1.50-1.86]) of similar risk (p value interaction=0.004). Conclusion In a large contemporary healthcare system, there was underutilization of statins across both sexes in primary prevention. High-risk women were less likely to be initiated on GDSI compared with high-risk men. GDSI significantly improved the survival in both sexes regardless of ASCVD risk group. Future strategies to ensure continued use of GDSI, specifically among women, should be explored.

Abstract
Abstract Magnolia biondii Pamp is an important ornamental tree species widely grown and used as a rootstock in the propagation of different Magnolia varieties. In the current studies, anatomical, physiological and endogenous hormones were studied to check the effect of IBA 750 mg/L on the adventitious rooting and to provide theoretical and technical support for the propagation of Magnolia biondii Pamp through stem cuttings. Two thousand stem cuttings were prepared and divided into two groups i.e., IBA treated cuttings and water control. For the evaluation of antioxidant enzyme activities, and endogenous hormones levels, samples were collected on the day of planting and each 5th day and further steps were carried out in the laboratory according to the protocols and proper precautions. For the anatomical observations, samples were collected on the 13th, 15th, and 17th day for IBA treated cuttings while 21st, 23rd, and 25th day for control. Collected samples were preserved in the FAA solution and further observations were carried out in the laboratory. Anatomical observations showed that it took 13 days for the differentiation of root primordia to the appearance of young adventitious roots in IBA treated cuttings, while it took 21 days to develop primordia in the control. Antioxidant enzyme activities involved in ROS were significantly higher in the IBA treated cuttings compared to control. POD showed a peak on the 13th day before the emergence of roots in IBA treated cuttings while it showed a peak on the 21st day in the control. PPO showed a peak on the 21st day in the IBA treated cuttings while it showed a peak on the 29th day in the control. SOD showed a peak on the 17th day in IBA treated cuttings, while it showed a peak on the 25th day in the control. Exogenous application of IBA enhanced the endogenous IAA and GA3 levels compared to CK, while it reduced the levels of ABA continuously at the time of rooting and then increased gradually. Inclusively, our study suggests that IBA 750 mg/L is efficient for the rooting of Magnolia biondii Pamp cuttings, as it enhanced the process of antioxidant enzyme activities, endogenous hormones levels and reduced the time of root formation which is evident from the anatomical observations.

Abstract
OBJECTIVE We examined guideline-directed statin intensity (GDSI) use and atherosclerotic cardiovascular disease (ASCVD) outcomes in patients with diabetes across a contemporary health care system. RESEARCH DESIGN AND METHODS Patients without preexisting ASCVD were categorized by diabetes status and 10-year ASCVD risk (borderline [5-7.4%], intermediate [7.5-19.9%], high [≥20%]). Mean ±SD time to start of or change to GDSI was calculated. Incident ASCVD and all-cause mortality association, stratified by ASCVD risk, was calculated using Cox regression. RESULTS Among 282,298 patients, 28,807 (10.2%) had diabetes and 253,491 (89.8%) did not. Only two-thirds of intermediate- and high-risk patients with diabetes were receiving GDSI therapy at 5-year follow-up. In fully adjusted models, patients with diabetes not taking a statin (vs. GDSI) had a significantly higher risk of stroke and mortality in the intermediate- and high-risk groups (hazard ratio for mortality 1.81 [95% CI 1.58-2.07] vs. 1.41 [1.26-1.57]; P for interaction < 0.01). CONCLUSIONS Significant gaps remain in GDSI use for high-risk patients with diabetes, conferring an increased risk of ASCVD outcomes and all-cause mortality.

Abstract
Cardiovascular disease (CVD) remains one of the leading causes of morbidity and mortality in aging adults across the United States. Prior studies indicate that the presence of atherosclerosis, the pathogenic basis of CVD, is linked with dementias. Alzheimer's disease (AD) and AD-related dementias are a major public health challenge in the United States. Recent studies indicate that ≈3.7 million Americans ≥65 years of age had clinical AD in 2017, with projected increases to 9.3 million by 2060. Treatment options for AD remain limited. Development of disease-modifying therapies are challenging due, in part, to the long preclinical window of AD. The preclinical incubation period of AD starts in midlife, providing a critical window for identification and optimization of AD risk factors. Studies link AD with CVD risk factors such as hypertension, inflammation, and dyslipidemia. Both AD and CVD are progressive diseases with decades-long development periods. CVD can clinically manifest several years earlier than AD, making CVD and its risk factors a potential predictor of future AD. The current review focuses on the state of literature on molecular and metabolic pathways modulating the heart-brain axis underlying the potential association of midlife CVD risk factors and their effect on AD and related dementias. Further, we explore potential CVD/dementia preventive strategies during the window of opportunity in midlife and the future of research in the field in the multiomics and novel biomarker use era.

Abstract
OBJECTIVE The main objective of performing this study was the mutational analysis of Forkhead box family member (FoxP3) and Interleukin-22 (IL-22) genes and their associations with systemic lupus erythematosus (SLE). MATERIALS AND METHODS A total of sixty blood samples were collected from SLE patients from different hospitals in Lahore. Proforma was based on American College of Rheumatology (ACR) criteria. The total time for this research was one year (2018-2019). DNA was extracted, and FoxP3 and IL-22 genes were polymerized through PCR and further sequenced through the Sanger Sequencing method. Chromas version 2.6.6 was used for the similarity index of sequences. NG_060763 and NG_007392.1 were used as Reference Sequences of IL-22 and FoxP3 genes, respectively. RESULTS Three already identified Single Nucleotide Polymorphisms (SNPs) in the IL-22 gene i.e., rs2227491, rs2227485, and rs2227513, were confirmed in the sequencing results of SLE patients. Results showed that there were nine novel mutations (27.27%) in the case of the IL-22 gene in the studied genotyped samples. These SNPs had remarkably increased allele T frequency in rs2227485 and allele C frequency in rs2227491 and rs2227513. On the other hand, in the case of FoxP3 gene exon 2, there was an addition of T at position 10 in the intronic portion, thus not involved in the progression of the disease. CONCLUSIONS The importance of cytokine-mediated signaling pathways, such as the IL-22 gene, is thus established. Novel variants in the IL-22 gene likely contributed significantly to the development of this autoimmune disorder. The current study found that the dysregulation of the inflammatory markers in SLE is not related to the FoxP3 gene, even though FoxP3 is implicated in the tolerance process.

Abstract
In patients with hypertriglyceridemia, a short-term low-saturated fat vs high-saturated fat diet induced lower plasma lipids and improved monocyte phenotypes. These findings highlight the role of diet fat content and composition for monocyte phenotypes and possibly cardiovascular disease risk in these patients.

Abstract
PURPOSE OF REVIEW Statins inhibit the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase in the liver and reduce atherosclerotic cardiovascular disease (ASCVD) risk by enhancing low-density lipoprotein (LDL) clearance from the circulation. In this review, we discuss their efficacy, safety, and real-world utilization to make a case for reclassifying statins as nonprescription over-the-counter drugs to improve access and availability with the overarching goal of increasing statin utilization in patients most likely to benefit from this class of therapy. RECENT FINDINGS Statin efficacy for reducing risk in primary and secondary ASCVD prevention populations as well as their safety and tolerability has been thoroughly investigated in large-scale clinical trials over the past 3 decades. Despite the overwhelming scientific evidence, statins are underutilized even among those at the highest ASCVD risk. We propose a nuanced approach to use statins as nonprescription drugs that leverages a multi-disciplinary clinical model. It integrates lessons learned from experiences outside the USA with a proposed Food and Drug Administration rule change that allows nonprescription drug products with an additional condition for nonprescription use.

Abstract
Introduction Adequate physical activity is an integral requirement for achieving cardiovascular health. Physical inactivity is the fourth leading cause of death worldwide. Hence, it is important to identify racial/ethnic groups that are less likely to achieve sufficient physical activity levels, and to address barriers to meeting physical activity requirements. Methods Cross-sectional data from the 2006–2015 National Health Interview Survey (NHIS) were used to compare self-reported sufficient physical activity among different racial/ethnic groups: non-Hispanic (NH) Whites, NH Blacks, NH Asians, and Hispanics in the United States. Sufficient physical activity was defined as ≥ 150 minutes per week of moderate-intensity physical activity, ≥ 75 minutes per week of vigorous-intensity physical activity, or ≥ 150 minutes per week of moderate and vigorous physical activity. Results The study sample consisted of 296,802 individuals, mean age ± standard error age 46.4 ± 0.10 years, 52% women, 70% NH White, 12% NH Black, 5% NH Asian, and 14% Hispanic. The prevalence of sufficient physical activity in the overall population was 46%, while it was 48% among NH Whites, 39% among NH Blacks, 45% among NH Asians, and 40% among Hispanics. In multivariable-adjusted models (odds ratio; 95% confidence interval), NH Blacks (0.79; 0.64,0.97), NH Asians (0.72; 0.62,0.85) and Hispanics (0.71; 0.61,0.82) were significantly less likely to engage in sufficient physical activity compared with NH Whites. Older age, women, and low income were inversely associated with sufficient physical activity, while a college education or higher was associated directly with it. Conclusions NH Black and Asian Americans and Hispanic adults were less likely to engage in sufficient physical activity levels compared with Whites. It is important to address barriers to meeting physical activity thresholds to help achieve optimal cardiovascular health.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are potent medications in the toolkit for treatment of atherosclerotic cardiovascular disease. These agents have been well studied in clinical trials supporting their efficacy in dramatically reducing low-density lipoprotein cholesterol (LDL-C) and impact on cardiovascular outcomes. Since the approval of commercial use for PCSK9 inhibitors in 2015, we have also gained significant experience in the use of these therapeutics in the real-world setting. In this article, we review current guideline recommendations, clinical trial evidence on efficacy and safety as well as data on cost-effectiveness, prescription and adherence. We focus primarily on the monoclonal antibody class of PCSK9 inhibitors in this review while also touching on other types of therapeutics that are under development.

Abstract
Abstract
Background
Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.
Methods
This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.
Results
Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.
Conclusion
The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

Abstract
This study explores the antioxidant activity, phytochemical screening, total phenolic and flavonoids contents in the extracts of four locally available weeds plants namely Convolvulus arvensis, Chenopodium murale, Avena fatua and Phalaris minor with different solvents. The antioxidant activities of these extracts were determined via various in-vitro methods such as total antioxidant activity (TAA), reducing power (RP), DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging and hydrogen peroxide scavenging assays. Phytochemical screening was performed both qualitatively as well as quantitatively. Total phenolic content (TPC) and total flavonoid content (TFC) were determined through Folin- Ciocalteu reagent and aluminium chloride methods respectively. Methanol-chloroform solvent showed the presence of a high amount of TPC in milligram of gallic acid equivalent per gram of dry weight (mg of GAE/g of DW) in the extracts of all weeds. Their descending sequence was Avena fatua (74.09) ˃ Phalaris minor (65.66) ˃ Chenopodium murale (64.04) ˃ Convolvulus arvensis (61.905), while, chloroform solvent found to be best solvent for the extraction of TFC. Methanol-chloroform solvent was also found to be best solvent for TAA (Total antioxidant activity assay) which showed values in milligram of ascorbic acid equivalent per gram of dry weight (mg of AAE /g of DW), for DPPH scavenging activity, reducing power (antioxidant activity) and hydrogen peroxide scavenging activity. Phytochemical screening indicated the presence of polyphenols, flavonoids, tannins, saponins, alkaloids and glycosides in these weeds.

Abstract
This study was aimed to investigate Carbofuran (CF)-induced pathological changes in cattle egret. Two hundred cattle egrets were reared and equally divided into four groups and given different CF concentrations (0.03 mg/L, 0.02 mg/L, 0.01 mg/L and 0 mg/L (control group)). Hematology, serum biochemistry, histopathology, and immunological markers were studied. Our results confirm that CF induces anemic conditions, leukocytosis, elevated liver enzymatic activity, and alterations in renal biomarkers. Moreover, specific microscopic lesions such as multifocal necrosis, pyknotic nuclei, hemorrhages, congestion, and inflammatory cell proliferation were observed in the liver, kidney, spleen, and thymus. These findings suggest that CF can induce harmful effects, so the application of this pesticide in the field must be strictly monitored to mitigate the possibility of exposure to non-target species.

Abstract
The current focus is on the overall pattern of seed storage present in the fragments of the soil of piedmont and alluvial landscapes of the environment. The present study predicted the seed banks of both soils of alluvial and piedmont zones in different ecological conditions and evaluate the potential of seeds in the restoration of both environments. The composition of the seed bank of soil is mainly affected by the alluvial environment and the structure of cleared area shows that more species of germinating annual grasses and growable seeds with the higher total number. Extant vegetation structures have an important role in the diversity of soil seed reservoirs, whose composition corresponded with the openness of the site. When in situ soil seed bank is recruited, it helps to restore only some components of the plant community in an alluvial environment. In our current research, it was confirmed that seed richness was higher in number at lower elevation (alluvial) than that at high elevation (piedmont). Seed richness showed a significant negative correlation with anions, cations, while significantly positive with altitude that suggests the richness pattern of the overall seed bank of the area is influenced by various environmental factors.

Abstract
Birds are among the best bio-indicators, which can guide us to recognize some of the main conservation concerns in ecosystems. Anthropogenic impacts such as deforestation, habitat degradation, modification of landscapes, and decreased quality of habitats are major threats to bird diversity. The present study was designed to detect anthropogenic causative agents that act on waterbird diversity in Tarbella Dam, Indus River, Pakistan. Waterbird censuses were carried out from March 2019 to February 2020 in multiple areas around the dam. A total of 2990 waterbirds representing 63 species were recorded. We detected the highest waterbird richness and diversity at Pehure whereas the highest density was recorded at Kabbal. Human activity impacts seemed to be the main factor determining the waterbird communities as waterbirds were negatively correlated with the greatest anthropogenic impacts. Waterbirds seem to respond rapidly to human disturbance.

Abstract
In present study, salivary microbial diversity of postpartum females was compared with nonpregnant females. Microbial colonization was raised in postpartum females especially those having oral health issues. Isolated bacterial species showed enhanced biofilm forming and multi drug resistance. Alpha diversity was decrease in postpartum female having oral health issues with PLWB. Bray-Curtis dissimilarity was highest between females with dental issues and different pregnancy outcomes.
The present study investigates the dysbiosis in salivary bacterial diversity by culture-dependent and independent methods. Culturable aerobic and facultative anaerobic bacterial diversity was studied in saliva collected from 267 postpartum and 54 nonpregnant females by using standard microbiological methods. For unculturable bacterial diversity, DNA from saliva samples of four selected females was sequenced by targeting V4 region of 16S rRNA. In postpartum females, S. mutans was significantly more prevalent. Its colonization was also seen significant among females having gingivitis (P < 0.01), dental caries (P < 0.01), and in those giving birth to low weight baby. In postpartum group, 65.16% females were culture positive for Staphylococcus, 12.73% Gram positive rods, 10.48% N. meningitides, 6.36% K. pneumoniae, 5.61% Enterobacter species and 2.62% E. coli. Isolates showed high biofilm forming ability and antibiotic resistance. Upon analysis of unculturable bacterial diversity, a total of 16 phyla and 156 genera were observed. Alpha diversity was decrease in postpartum female having oral health issues with pre-term low weight birth, compared to females with full term birth. Bray-Curtis dissimilarity was highest between female with dental issues and different pregnancy outcomes. Bacterial diversity and abundance altered among females with different oral health conditions and pregnancy outcomes, and also have pathogenic potential.

Abstract
AIMS Emerging evidence suggests that remnant cholesterol (RC) promotes atherosclerotic cardiovascular disease (ASCVD). We aimed to estimate RC-related risk beyond low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (apoB) in patients without known ASCVD. METHODS AND RESULTS We pooled data from 17 532 ASCVD-free individuals from the Atherosclerosis Risk in Communities study (n = 9748), the Multi-Ethnic Study of Atherosclerosis (n = 3049), and the Coronary Artery Risk Development in Young Adults (n = 4735). RC was calculated as non-high-density lipoprotein cholesterol (non-HDL-C) minus calculated LDL-C. Adjusted Cox models were used to estimate the risk for incident ASCVD associated with log RC levels. We also performed discordance analyses examining relative ASCVD risk in RC vs. LDL-C discordant/concordant groups using difference in percentile units (>10 units) and clinically relevant LDL-C targets. The mean age of participants was 52.3 ± 17.9 years, 56.7% were women and 34% black. There were 2143 ASCVD events over the median follow-up of 18.7 years. After multivariable adjustment including LDL-C and apoB, log RC was associated with higher ASCVD risk [hazard ratio (HR) 1.65, 95% confidence interval (CI) 1.45-1.89]. Moreover, the discordant high RC/low LDL-C group, but not the low RC/high LDL-C group, was associated with increased ASCVD risk compared to the concordant group (HR 1.21, 95% CI 1.08-1.34). Similar results were shown when examining discordance across clinical cutpoints. CONCLUSIONS In ASCVD-free individuals, elevated RC levels were associated with ASCVD independent of traditional risk factors, LDL-C, and apoB levels. The mechanisms of RC association with ASCVD, surprisingly beyond apoB, and the potential value of targeted RC-lowering in primary prevention need to be further investigated.

Abstract
BACKGROUND Current American College of Cardiology/American Heart Association guidelines recommend using the 10-year atherosclerotic cardiovascular disease (ASCVD) risk to guide statin therapy for primary prevention. Real-world data on adherence and consequences of nonadherence to the guidelines in primary are limited. We investigated the guideline-directed statin intensity (GDSI) and associated outcomes in a large health care system, stratified by ASCVD risk. METHODS Statin prescription in patients without coronary artery disease, peripheral vascular disease, or ischemic stroke were evaluated within a large health care network (2013-2017) using electronic medical health records. Patient categories constructed by the 10-year ASCVD risk were borderline (5%-7.4%), intermediate (7.5%-19.9%), or high (≥20%). The GDSI (before time of first event) was defined as none or any intensity for borderline, and at least moderate for intermediate and high-risk groups. Mean (±SD) time to start/change to GDSI from first interaction in health care and incident rates (per 1000 person-years) for each outcome were calculated. Cox regression models were used to calculate hazard ratios for incident ASCVD and mortality across risk categories stratified by statin utilization. RESULTS Among 282 298 patients (mean age ≈50 years), 29 134 (10.3%), 63 299 (22.4%), and 26 687 (9.5%) were categorized as borderline, intermediate, and high risk, respectively. Among intermediate and high-risk categories, 27 358 (43%) and 8300 (31%) patients did not receive any statin, respectively. Only 17 519 (65.6%) high-risk patients who were prescribed a statin received GDSI. The mean time to GDSI was ≈2 years among the intermediate and high-risk groups. At a median follow-up of 6 years, there was a graded increase in risk of ASCVD events in intermediate risk (hazard ratio=1.15 [1.07-1.24]) and high risk (hazard ratio=1.27 [1.17-1.37]) when comparing no statin use with GDSI therapy. Similarly, mortality risk among intermediate and high-risk groups was higher in no statin use versus GDSI. CONCLUSIONS In a real-world primary prevention cohort, over one-third of statin-eligible patients were not prescribed statin therapy. Among those receiving a statin, mean time to GDSI was ≈2 years. The consequences of nonadherence to guidelines are illustrated by greater incident ASCVD and mortality events. Further research can develop and optimize health care system strategies for primary prevention.

Abstract
Various concentrations (0.01, 0.03 and 0.05 wt ratios) of graphene oxide (GO) nanosheets were doped into magnesium oxide (MgO) nanostructures using chemical precipitation technique. The objective was to study the effect of GO dopant concentrations on the catalytic and antibacterial behavior of fixed amount of MgO. XRD technique revealed cubic phase of MgO, while its crystalline nature was confirmed through SAED profiles. Functional groups presence and Mg-O (443 cm-1) in fingerprint region was evident with FTIR spectroscopy. Optical properties were recorded via UV-visible spectroscopy with redshift pointing to a decrease in band gap energy from 5.0 to 4.8 eV upon doping. Electron-hole recombination behavior was examined through photoluminescence (PL) spectroscopy. Raman spectra exhibited D band (1338 cm-1) and G band (1598 cm-1) evident to GO doping. Formation of nanostructure with cubic and hexagon morphology was confirmed with TEM, whereas interlayer average d-spacing of 0.23 nm was assessed using HR-TEM. Dopants existence and evaluation of elemental constitution Mg, O were corroborated using EDS technique. Catalytic activity against methyl blue ciprofloxacin (MBCF) was significantly reduced (45%) for higher GO dopant concentration (0.05), whereas bactericidal activity of MgO against E. coli was improved significantly (4.85 mm inhibition zone) upon doping with higher concentration (0.05) of GO, owing to the formation of nanorods.

Abstract
Lipids and lipoproteins are the target of many novel therapeutics and are an area with great potential for the prevention and treatment of cardiovascular disease (CVD). Reduction of low-density lipoprotein cholesterol has been the mainstay of reducing the burden of CVD, however, several other atherogenic particles have more recently come into the spotlight as potential avenues for primary and/or secondary prevention of CVD. These include triglycerides, high sensitivity C-reactive protein, apolipoprotein A, apolipoprotein C3 and lipoprotein(a). In this review, we showcase novel therapeutics to target lipid and cardiovascular risk reduction that are either in development or that have recently been approved for use. We discuss the mechanisms of action, data from clinical trials and expected effects of each therapy based on the current body of literature.

Abstract
Metastatic cutaneous SCC carries a poor prognosis with five-year survival of 25%-57%. The aim of this study is to examine the outcomes following surgery with adjuvant therapy for management of metastatic cSCC in a UK-based population. This is a retrospective review of patients with metastatic cSCC of the head and neck who underwent primary surgery at a regional center during a six-year period. Overall and disease specific survival were calculated using Kaplan-Meier and log-rank tests. Results were reported as hazard ratios (HR) with 95% confidence intervals. Forty-five patients met the inclusion criteria. The mean time to discovery of metastases was 9.3 months (range, 0-40 months). Only two patients (4%) had discovery of metastases after two years, with none after 3.3 years. The overall five5-year survival was 31% (95% CI 15%to 48%) with two-year survival at 48% (95% CI 31%to 63%). The median OS survival was 722 days (95% CI 607to 1359). Patients aged >80 years had a decreased OS. This is the largest UK based study documenting the overall and disease specific survival associated with metastatic cutaneous SCC of the head and neck. Our overall survival is comparable to similar studies, but remains poor. Total number of involved nodes, and lymph node ratio were not statistically significant.

Abstract
To further reduce the burden of cardiovascular disease (CVD) and expand prevention efforts, the American Heart Association (AHA) introduced in 2010 the concept of Ideal Cardiovascular Health (ICH), which includes 7 metrics (smoking status, body mass index, physical activity, diet, total cholesterol, blood pressure, and fasting plasma glucose). Limited data exist on the relation between ICH and long-term CVD risk. The Heart Strategies Concentrating on Risk Evaluation (Heart SCORE) study cohort was used to examine the relation between ICH and incident major adverse cardiovascular events (MACE: first occurrence of death, myocardial infarction, stroke, acute ischemic syndrome, or coronary revascularization). The 7 factors of the ICH were scored at study entry on a 0 to 2 scale, resulting in possible range of 0 to 14, with higher scores representing "better" health. Cox regression analyses were used to estimate hazard ratios (HR) of MACE, along with 95% confidence intervals. Over a median follow-up of 12 years, the study population (n = 1,863, 67% women, 42% Black race, mean age 59 years [range 45 to 75]) had 218 MACE. In unadjusted analysis, the ICH score (per 1 unit) was associated with an estimated 12% lower risk of MACE (HR [95% Confidence Interval]: 0.88 [0.82, 0.93]). Adjusting for demographics, education, and quality of life, ICH score was associated with a 10% lower risk of MACE (HR 0.90 [0.84, 0.96]). In a community-based sample of adults, the AHA ICH construct, which includes 7 modifiable CVD risk factors, appears to be a valid measure for predicting long-term risk of MACE.

Abstract
PURPOSE OF REVIEW Genetic, epidemiological, and translational data indicate that Lipoprotein (a) [Lp(a)] is likely in the causal pathway for atherosclerotic cardiovascular diseases as well as calcification of the aortic valves. RECENT FINDINGS Lp(a) is structurally similar to low-density lipoprotein, but in addition to apolipoprotein B-100, it has a glycoprotein apolipoprotein(a) [apo(a)], which is attached to the apolipoprotein B-100. Several distinctive properties of Lp(a) can be attributed to the presence of apo(a). This review discusses the current state of literature on pathophysiological and clinical aspects of Lp(a). After five decades of research, the understanding of Lp(a) structure, biochemistry, and pathophysiology of its cardiovascular manifestations still remains less than fully understood. Universally, Lp(a) elevation may be the most predominant monogenetic lipid disorder with approximate prevalence of Lp(a)>50 mg/dL among estimated >1.4 billion people. This makes a compelling rationale for diagnosing and managing Lp(a)-mediated risk. In addition to discussing various cardiovascular phenotypes of Lp(a) and associated morbidity, we also outline current and emerging therapies aimed at identifying a definitive treatment for elevated Lp(a) levels.

Abstract
BACKGROUND South Asians are at a significantly increased risk of atherosclerotic cardiovascular disease (ASCVD). For a major portion of the South Asian population, the cardiovascular disease events occur at a relatively younger age, are associated with worse outcomes, and have potentially more severe socioeconomic implications compared to their western counterparts. METHODS The term "South Asian" typically constitutes individuals from India, Pakistan, Nepal, Bhutan, Bangladesh, Sri Lanka, and Maldives, including expatriates as well as their families from these countries. Based on this, South Asians form approximately 25% of the world's population, with a high ASCVD burden in this group. In this review, we discuss the pathophysiological factors underlying ASCVD in South Asians, the dyslipidemia types and management, and discuss approaches to improve the overall ASCVD prevention efforts in this large subset population of the world. Although the pathophysiological mechanisms underlying the excess risk of cardiovascular disease in South Asians are multifactorial, dyslipidemia is a primary risk factor for the incidence and prevalence of this disease. The traditional "South Asian" dyslipidemia pattern includes levels of low-density lipoprotein cholesterol (LDL-C) in the normal range with a high concentration of LDL particles, elevated triglycerides, low levels of high-density lipoprotein cholesterol (HDL-C) with dysfunctional HDL particles, and high levels of lipoprotein(a). CONCLUSION While combined efforts to study the expatriate South Asians in western countries have been able to identify South Asian specific dyslipidemias, causal associations and optimal management remain relatively less explored. Larger scale studies are needed to better quantify the relationship of each lipid parameter with ASCVD risk among South Asians as well as optimal lipid targets and management strategies to reduce morbidity and mortality in this high-risk group.

Abstract
BACKGROUND South Asians are at a significantly increased risk of type 2 diabetes (T2D) and cardiovascular disease (CVD), are diagnosed at relatively younger ages, and exhibit more severe disease phenotypes as compared with other ethnic groups. The pathophysiological mechanisms underlying T2D and CVD risk in South Asians are multifactorial and intricately related. METHODS A narrative review of the pathophysiology of excess risk of T2D and CVD in South Asians. RESULTS T2D and CVD have shared risk factors that encompass biological factors (early life influences, impaired glucose metabolism, and adverse body composition) as well as behavioral and environmental risk factors (diet, sedentary behavior, tobacco use, and social determinants of health). Genetics and epigenetics also play a role in explaining the increased risk of T2D and CVD among South Asians. Additionally, South Asians harbor several lipid abnormalities including high concentration of small-dense low-density lipoprotein (LDL) particles, elevated triglycerides, low high-density lipoprotein (HDL)- cholesterol levels, dysfunctional HDL particles, and elevated lipoprotein(a) that predispose them to CVD. CONCLUSION In this comprehensive review, we have discussed risk factors that provide insights into the pathophysiology of excess risk of T2D and CVD in South Asians.

Abstract
Cardiovascular disease prevention is a complicated field requiring similar resource allocation and training as any other subspecialty in cardiology. To highlight the increasing need for primordial, primary and secondary cardiovascular disease prevention at a population level, it is necessary to have a clear vision for not only adequate training in the field but also sample career trajectories that today’s fellows-intraining (FIT) and early career (EC) physicians can use as a reference. However due to less centralized training, reduced exposure to the discipline and no clear institutional champions, direct access to “role model” careers in cardiovascular disease prevention may be lacking for today’s generation of trainees. These trends may change with more formalized recognition and more visibility of career trajectories in the field. In the current short report, we propose career pathways in cardiovascular disease prevention that can serve as a board resource roadmap for today’s FIT/EC physicians to design their careers in cardiovascular disease prevention. We explore three types of preventive cardiologists prototypes including; “the researcher”, “the clinician” and “the academic” preventive cardiologist models. These models are based on experiences gained in separate preventive cardiology training fellowships in addition to general cardiology training. Further, with advances in the scientific technologies, we highlight the future trajectory in the field. Preventive cardiology, although currently not the most desired path for FIT/EC physicians to pursue today, has the potential to be seen as the lucrative and essential training field in the future.

Abstract
BACKGROUND Accumulation of lipoprotein X (LpX) in blood can cause severe hypercholesterolemia and cutaneous xanthomas. Monocytes sensitively sense lipid changes in circulation and contribute to inflammation. However, how monocytes respond to LpX is undefined. OBJECTIVE We examined the phenotype of monocytes from a patient, who had LpX, severe hypercholesterolemia, and extensive cutaneous xanthomas, and effects of semiselective plasmapheresis therapy (SPPT). METHOD Fluorescence-activated cell sorting and adhesion assays were used to examine monocyte phenotype and ex vivo oxidized low-density lipoprotein uptake and adhesion in the patient before and after treatment with SPPT. Effects of plasma from the patient on the phenotype and adhesion of monocytes from a healthy participant were determined. RESULTS SPPT improved hypercholesterolemia and cutaneous xanthomas. Before treatment, the patient had lower frequency of nonclassical monocytes but higher frequency of intermediate monocytes than the control participant. Before treatment, monocytes from the patient with LpX showed more intracellular lipid accumulation, alterations in several cell surface markers and intracellular cytokines, as well as enhanced oxidized low-density lipoprotein uptake and reduced adhesion compared with control. After SPPT, the phenotypes of monocytes from the patient with LpX were similar to control monocytes. Incubation with plasma from the patient before treatment as compared with plasma from the control participant or the patient after treatment increased CD11c expression and adhesion of monocytes from a healthy participant. CONCLUSION LpX-induced hypercholesterolemia increased lipid accumulation and altered the phenotype of monocytes, which may contribute to cutaneous xanthoma development. Removal of LpX by SPPT reduced lipid accumulation and improved monocyte phenotype, likely contributing to xanthoma resolution.

Abstract
Geographic information system (GIS) is designed to generate maps, manage spatial datasets, perform sophisticated “what if” spatial analyses, visualize multiple spatial datasets simultaneously, and solve location-based queries. The impact of big data is in every industry, including the GIS. The location-based big data also known as big spatial data has significant implications as it forces the industry to contemplate how to acquire and leverage spatial information. In this study, a comprehensive taxonomy is created to provide a better understanding of the uses of GIS and big spatial data. The taxonomy is made up of big data technologies, GIS data sources, tools, analytics, and applications. The authors look into the importance of big spatial data and its implications, review the data sources, and GIS analytics, applications, and GIS tools. Furthermore, in order to guide researchers interested in GIS, the challenges that require substantial research efforts are taken into account. Lastly, open issues in GIS that require further observation are summarized.

Abstract
Background Circulating galectin‐3 levels provide prognostic information in patients with established heart failure (HF), but the associations between galectin‐3 levels and other incident cardiovascular events in asymptomatic individuals at midlife and when remeasured ≈15 years later are largely uncharacterized. Methods and Results Using multivariable Cox proportional hazards models, we identified associations between plasma galectin‐3 levels (hazard ratio [HR] per 1 SD increase in natural log galectin‐3) and incident coronary heart disease, ischemic stroke, HF hospitalization, and total mortality in ARIC (Atherosclerosis Risk in Communities) participants free of cardiovascular disease at ARIC visit 4 (1996–1998; n=9247) and at ARIC visit 5 (2011–2013; n=4829). Higher galectin‐3 level at visit 4 (median age 62) was independently associated with incident coronary heart disease (adjusted HR, 1.30; 95% CI, 1.06–1.60), ischemic stroke (HR, 1.42; 95% CI, 1.01–2.00), HF (HR, 1.44; 95% CI, 1.17–1.76), and mortality (HR, 1.56; 95% CI, 1.35–1.80). At visit 5 (median age, 74), higher galectin‐3 level was associated with incident HF (HR, 1.93; 95% CI, 1.15–3.24) and total mortality (HR, 1.70; 95% CI, 1.15–2.52), but not coronary heart disease or stoke. Individuals with the greatest increase in galectin‐3 levels from visit 4 to visit 5 were also at increased risk of incident HF and total mortality. Conclusions In a large, biracial community‐based cohort, galectin‐3 measured at midlife and older age was associated with increased risk of cardiovascular events. An increase in galectin‐3 levels over this period was also associated with increased risk.

Abstract
The objective of this study is to analyze the effects of zirconium (Zr) and silver (Ag) doping on the photoactivity of titania (TiO2). Zr–Ag (ZA) co-doped TiO2 products were fabricated via sol–gel technique and their properties (structural and chemical) were characterized. The weight ratio of TiO2 was fixed, while weight ratios of Zr and Ag were varied from 2 to 4, 6 and 8 wt% while synthesized samples were calcined at 400 °C for 3 h. The XRD results demonstrated that the incorporation of metal doping agents failed to alter the host material's lattice structure, however, its crystallite size was reduced from 13.54 to 5.05 nm with increasing Zr4+ and Ag+ concentrations. FTIR spectroscopy was used to examine various functional groups. In the attained spectra, an ample absorption peak between 500 and 1000 cm−1 was recorded, which was ascribed to Ti–O–Ti linkage vibration mode present within TiO2. Surface morphology, microstructure, SAED patterns and elemental composition were examined with FE-SEM, HR-TEM and EDX, which served to confirm the ZA-doped TiO2 product. Band gap energy of the co-doped material was significantly reduced as indicated by a higher wavelength redshift in the spectra. The photoactivity and kinetics of photo-products were investigated by observing photo-decolorization of methylene blue (MB) under a radiation source. Photodecomposition of MB was dramatically enhanced when titania co-doped with Zr and Ag was employed compared to un-doped or mono-doped TiO2. The ZA (8 wt%) co-doped TiO2 photocatalyst depicted the maximum MB removal efficiency (∼93%) within 90 min under a light source. The objective of this study is to analyze the effects of zirconium (Zr) and silver (Ag) doping on the photoactivity of titania (TiO2).![]()

Abstract
Most of the mortalities among Diabetic Nephropathy patients are cardiovascular, if we identify the risk factor, measures can be taken to prevent it. Hence an objective was set to evaluate the association between carotid artery intima media thickness (CIMT) with eGFR in patients of CKD stage III, IV and V among patients with type 2 diabetes mellitus; also, correlation with age, BMI, lipid profile. This cross-sectional, observational study was performed in 70 patients in different stages of CKD in Diabetic Patients selected by Inclusion Criteria (Diabetic nephropathy patients with stages III, IV, V and exclusion Criteria (Acute kidney injury, History of carotid surgery, Patients of MI and stroke). This study was performed in Department of Nephrology, Dhaka Medical College in collaboration with the Department of Radiology and Imaging, laboratory of Department of Biochemistry and Department of Microbiology at Dhaka Medical College Hospital (By standard method in laboratory) from 1st January 2016 to 31st December 2016. eGFR was measured by MDRD formula and the CIMT was measured using an ultrasonographic examination. The mean CIMT was 0.9±0.21mm, and 62.9% of the subjects showed IMT thickening (≥1mm). The carotid IMT elevated significantly with the stage progression of CKD (Overall eGFR mean 28.8±14.5mL/min/1.73m² in CIMT<1mm with range from 6 to 54 and 9.1±9.0mL/min/1.73m² in CIMT ≥1mm with range from 3 to 32 (p=0.001). The eGFR was significantly lower in the patients with CIMT thickening than those without CIMT thickening. eGFR was also significantly associated with CKD stages (p=0.001), serum creatinine (p=0.001), BMI (r = -0.330, p=0.005), and negatively associated with age group, duration of hypertension, smoking. However, the CIMT was not significantly different among the patients at different stages of diabetic nephropathy (r = -0.172, p=156) and age group. It has been concluded that the mean CIMT was markedly high in patients with CKD compared to normal expected value. This study showed a relationship between the CIMT and the renal parameters as eGFR and the stages of diabetic nephropathy with a confirm association between the CIMT and diabetic macroangiopathy.
