Addressing the Health Needs of Indian Americans in the Greater Philadelphia Region Through a Scoping Survey: Cancer Screening Assessment.

Despite higher income and education, there are profound health disparities among Asian Americans. These disparities are highlighted in particular by screening behaviors for cancer. Between 1998 and 2008, cancer rates increased threefold among Indian Americans, raising concern that cancer screening in this group may be especially low. To better understand cancer screening behavior, we collected data from a total of 157 self-identifying Indian Americans residing in the greater Philadelphia area. Nearly all participants reported having health insurance (98.7%), and most had received a physical exam within a year (87.3%). Only17.4% of the participants were referred for mammography, while 30% of participants over age 30 were referred for ovarian cancer screening. Just 4 participants were recommended for pancreatic cancer screening. The findings contribute new information to the understanding of health needs of Indian Americans residing in the greater Philadelphia region and reveal a need for greater focus on preventive care.

Assessing Physicians' Recommendations for Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) Testing Among Minority Populations in Greater Philadelphia and New York City.

Deaths from liver cancer are on the rise and disproportionately affect minority racial/ethnic groups. In this study, we examined associations between physicians' recommendations for hepatitis B virus (HBV) and hepatitis C virus (HCV) screening and sociodemographic and lifestyle factors among minority populations in the areas of Greater Philadelphia and New York City. Using Poisson regression with robust variance estimation, we evaluated potential associations for 576 Hispanic American (HA), African American (AA), and Asian Pacific American (APA) adults, using blood tests as an outcome measure, with adjustment for sociodemographic factors We found that APAs (34.2%) were most likely to have a physician recommend HBV and HCV screening tests (34.2% and 27.1%, respectively), while HAs were least likely to receive an HBV recommendation (15.0%) and AAs were least likely to receive an HCV recommendation (15.3%). HAs were significantly likely to have never received a blood test for either HBV or HCV (RR = 1.25, 95% CI: 1.05, 1.49). APAs were significantly more likely to receive a screening recommendation for HBV (RR = 1.10, 95%CI: 1.01, 1.20) and to have a blood test (RR = 1.57, 95% CI: 1.06, 2.33). Our findings show that, among HAs, AAs, and APAs, physician recommendations are strongly associated with patients undergoing blood tests for HBV and HCV and that minority populations should increasingly be recommended to screen for HBV and HCV, especially given their elevated risk.

Induction of Endometrial HOXA 10 Gene Expression by Vitamin D and its Possible Influence on Reproductive Outcome of PCOS Patients Undergoing Ovulation Induction Procedure.

Background and Objectives: Polycystic ovarian syndrome (PCOS) is one of the most common endocrinopathies in women frequently presenting with anovulatory infertility. Low successful pregnancy and live birth rates even after successful ovulation induction (OI) and in vitro fertilization (IVF) in these patients indicate that endometrial dysfunction may be another important factor contributing to infertility. Vitamin D acting through nuclear receptors induces the expression of various genes required for cell growth and differentiation and plays a crucial role in reproduction. Homeobox 10 (HOXA10) may be one of the potential targets for vitamin D action. HOXA10 gene product promotes the differentiation of endometrial cells, making the endometrium receptive for implantation. The present study was undertaken to determine the effect of circulating vitamin D levels on HOXA10 gene expression in endometrial tissues and its possible influence on the reproductive outcome of PCOS patients undergoing OI procedure. Materials and Methods: A prospective cohort study was conducted on 110 infertile PCOS patients. The patients were divided into two groups: Group 1: Vitamin D ³20 ng/ml, Group 2: Vitamin D <20 ng/ml. Endometrial samples were obtained from 22 patients using pipelle biopsy, used to determine HOXA10 mRNA (messenger ribonucleic acid) expression by quantitative RT-PCR (reverse transcription-polymerase chain reaction) and protein expression by Western blotting. OI was performed using Clomiphene citrate or Letrozole from the 3rd day of the cycle, and patients were followed up for a maximum of five cycles. Attainment of successful pregnancy was considered a positive outcome. Results: Both the groups were similar in mean age and other endocrine parameters. Serum vitamin D levels were significantly low (P < 0.001), and BMI (body mass index) was significantly high (P = 0.032) in group 2 compared to group 1. Endometrial HOXA10 mRNA (by quantitative rtPCR) and protein expression (by western blotting) were significantly low in group 2 compared to group 1. The clinical pregnancy rate was low in group 2 (28.6%) compared to group 1 (42.3%), but this difference was not significant (P = 0.22). On regression analysis adjusted for age and BMI, vitamin D was an independent predictor of successful pregnancy after OI (P = 0.09). Conclusion: Circulating vitamin D levels influence the endometrial HOXA10 gene expression, and this may be reflected on the reproductive outcome of infertile PCOS patients undergoing OI.

Renal Dysfunction in Prediabetes: Confirmed by Glomerular Hyperfiltration and Albuminuria.

Objectives Prediabetes is defined as an intermediate state of hyperglycemia with glucose levels above normal but below the diagnostic cutoff of diabetes mellitus. Prediabetes is considered as an important risk factor for the development of diabetes and complications associated with diabetes. Since glomerular hyperfiltration (elevated GFR) and albuminuria represent early and reversible stages of kidney damage seen in patients with type 2 diabetes, we aim to assess the impact of hyperglycemia in prediabetic range on renal functions measured by estimated GFR and urine albumin excretion (UAE). Materials and Methods The study included 1,031 patients aged 30 to 70 years, attending regular health checkup. Patients were grouped as normal, prediabetes, and diabetes according to the American Diabetic Association (ADA) criteria based on fasting blood sugar and hemoglobin A1c (HbA1c). Further, the patients were grouped into multiple subgroups based on age and gender. UAE was measured by using immunoturbidimetric method, and GFR was estimated by chronic kidney disease epidemiology collaboration (CKD EPI) equation. Statistical Analysis Prevalence of hyperfiltration (estimated glomerular filtration rate above the age and gender specific 95th percentile), and albuminuria in prediabetes and diabetes was compared with normal controls. Odds ratio and 95% confidence interval were calculated by using logistic regression analysis to predict the occurrence of hyperfiltration in prediabetes and diabetes. Analysis of variance followed by post hoc comparison was done to assess the significance of difference, and p -value < 0.05 was considered statistically significant. Results Prevalence of hyperfiltration was more in prediabetes and diabetes compared with normal controls, and it increased with surging HbA1c level that was shown as higher odds ratio for hyperfiltration in both the groups. UAE was more in the prediabetes and diabetes group when compared with normal controls, but the difference was significant only in diabetes. Conclusion Since glomerular hyperfiltration represents an early and reversible stage of renal damage manifesting before the appearance of albuminuria, elevated GFR can be used to identify asymptomatic patients with intermediate hyperglycemia having high risk of developing nephropathy in the future. Prediabetes represents a window of opportunity to initiate preventive strategies at an early stage before the occurrence of significant renal damage.

Immunohistochemical expression of tumor necrosis factor-like weak inducer of apoptosis and fibroblast growth factor-inducible immediate early response protein 14 in oral squamous cell carcinoma and its implications.

AIM: To study the expression of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) and fibroblast growth factor-inducible immediate early response protein 14 (Fn14) in oral squamous cell carcinoma (OSCC), to elucidate the possible role of TWEAK-Fn14 in OSCC development. METHODS: Immunohistochemistry for TWEAK-Fn14 was performed on 61 oral mucosal samples: healthy oral mucosa (HOM; N = 15); oral dysplastic lesions (ODL; N = 15); and OSCC (N = 31). Extent of staining (ES) and immunoreactive score (IRS) were assessed. The data was statistically analyzed. RESULTS: All OSCC expressed TWEAK, and the Fn14 expression was noted in 90% of OSCC. A significant difference in the TWEAK and Fn14 expression was noted among the groups. ES and IRS of TWEAK-Fn14 significantly increased in OSCC compared with ODL and HOM. ES of TWEAK was significantly higher than Fn14 in all 3 groups. ES of TWEAK-Fn14 was significantly higher at the invasive tumor front (ITF) than in the whole tumor. TWEAK-Fn14 showed a significant association with clinicopathological parameters of prognostic significance. CONCLUSION: Findings suggest that TWEAK and Fn14 may participate in the growth and progression of OSCC. Increased expression of TWEAK-Fn14 at the ITF may facilitate increased proliferation, altered differentiation and invasion.

Evaluation of renal function in subclinical hypothyroidism.

INTRODUCTION: Patients with subclinical hypothyroidism (SCH) have a few or no symptoms or signs of thyroid dysfunction and thus by its very nature, SCH is a laboratory diagnosis. Serum creatinine is elevated and glomerular filtration rate (GFR) values are reversibly reduced in overt hypothyroid patients. We hypothesize that SCH also may be associated with low GFR. AIMS AND OBJECTIVES: The objective of this study was (1) to know the effect of SCH on kidney function, (2) to find the correlation between the renal function parameter creatinine, estimated GFR (eGFR), and thyroid-stimulating hormone (TSH), and (3) to know if creatinine values can be predicted by TSH values in SCH cases. MATERIALS AND METHODS: This is a hospital-based cross-sectional study for 1 year. A total of 608 subjects of either sex were included in the study and were divided into 3 groups: (1) SCH, (2) overt hypothyroidism (OHT), and (3) euthyroidism (ET). TSH, free triiodothyronine, free thyroxine, and serum creatinine were estimated and eGFR was calculated using modification of diet in renal disease study equation and the chronic kidney disease epidemiology collaboration equations. RESULTS: Serum creatinine levels were higher and eGFR was lower significantly in the subclinical hypothyroid group when compared to the control ET group (P < 0.001). The overtly hypothyroid group had significantly higher levels of serum creatinine and lower eGFR when compared to both the groups (P < 0.001). Significant correlation between TSH, creatinine, and eGFR was found in OHT group only. Linear regression analysis showed the regression in creatinine upon TSH is attributable to 44.5% among OHT group, 48.2% in SCH group. CONCLUSION: It can be concluded that the SCH group behaves biochemically similar to OHT group and changes in serum creatinine reflect tissue hypothyroidism in SCH cases.

Urine Albumin Excretion as a Marker of Acute Glycemic Changes in Isolated Postprandial Hyperglycemia.

INTRODUCTION: Postprandial hyperglycemia is a major risk factor for the development of cardiovascular diseases (CVDs), and Most of the times it occurs in patients with normal glycemic control diagnosed by fasting blood glucose (FBG) and glycated hemoglobin levels. Urine albumin excretion (UAE) is an independent predictor of CVD risk. AIM: To estimate UAE in isolated postprandial hyperglycemia (IPPHG) patients and to assess the relationship of UAE with FBG and postprandial blood glucose (PPBG) levels. SETTINGS AND DESIGN: A cross-sectional study was carried out in 318 patients with Type II diabetes in the age group 30-60 years for 6 months. MATERIALS AND METHODS: Patients were divided into five groups based on their FBG and PPBG values. UAE and lipid profile were measured in all the groups. STATISTICAL ANALYSIS: UAE and lipid profile in different groups were compared using ANOVA. Regression analysis was used to predict the variation of UAE with FBG, PPBG, and total cholesterol (TC). RESULTS: Patients with IPPHG had significantly higher albumin excretion compared to normoglycemia (NG) group [P < 0.0001]. In impaired glucose tolerance and isolated fasting hyperglycemia groups, it did not differ significantly from NG group [P = 0.206 and P = 0.173]. Lipid profile did not show any significant difference between the groups. On regression analysis, PPBG but not FBG or TC correlated positively with UAE. CONCLUSION: UAE is easy, less expensive, and Widely available method done on spot urine samples which predicts the acute glycemic changes and increased risk of developing CVDs in patients with IPPHG.

Annexin A2 and its downstream IL-6 and HB-EGF as secretory biomarkers in the differential diagnosis of Her-2 negative breast cancer.

Background AnnexinA2 (AnxA2) membrane deposition has a critical role in HB-EGF shedding as well as IL-6 secretion in breast cancer cells. This autocrine cycle has a major role in cancer cell proliferation, migration and metastasis. The objective of the study is to demonstrate annexinA2-mediated autocrine regulation via HB-EGF and IL-6 in Her-2 negative breast cancer progression. Methods Secretory annexinA2, HB-EGF and IL-6 were analysed in the peripheral blood sample of Her-2 negative ( n = 20) and positive breast cancer patients ( n = 16). Simultaneously, tissue expression was analysed by immunohistochemistry. The membrane deposition of these secretory ligands and their autocrine regulation was demonstrated using triple-negative breast cancer cell line model. Results Annexina2 and HB-EGF expression are inversely correlated with Her-2, whereas IL-6 expression is seen in both Her-2 negative and positive breast cancer cells. RNA interference studies and upregulation of annexinA2 proved that annexinA2 is the upstream of this autocrine pathway. Abundant soluble serum annexinA2 is secreted in Her-2 negative breast cancer (359.28 ± 63.73 ng/mL) compared with normal (286.10 ± 70.04 ng/mL, P < 0.01) and Her-2 positive cases (217.75 ± 60.59 ng/mL, P < 0.0001). In Her-2 negative cases, the HB-EGF concentrations (179.16 ± 118.81 pg/mL) were highly significant compared with normal (14.92 ± 17.33 pg/mL, P < 0.001). IL-6 concentrations were increased significantly in both the breast cancer phenotypes as compared with normal ( P < 0.001). Conclusion The specific expression pattern of annexinA2 and HB-EGF in triple-negative breast cancer tissues, increased secretion compared with normal cells, and their major role in the regulation of EGFR downstream signalling makes these molecules as a potential tissue and serum biomarker and an excellent therapeutic target in Her-2 negative breast cancer.

Chronic Periodontitis in Type 2 Diabetes Mellitus: Oxidative Stress as a Common Factor in Periodontal Tissue Injury.

INTRODUCTION: The prevalence of periodontitis is significantly higher among people with poorly controlled diabetes mellitus. Majority of tissue destruction in periodontitis is considered to be the result of an aberrant inflammatory/immune response to microbial plaque and involve prolonged release of reactive oxygen species (ROS). There is increased evidence for compromised antioxidant capacity in periodontal tissues and fluids which may be an added factor for tissue damage in periodontitis. AIM: To study the possible role of Reactive oxygen species (ROS) and antioxidant status in blood among chronic periodontitis patients with and without Type 2 Diabetes mellitus. MATERIALS AND METHODS: The study comprised of total 100 subjects among which 25 were normal healthy controls, 25 were gingivitis patients, 25 were chronic periodontitis patients (CP) and 25 were having chronic periodontitis with type 2 diabetes (CP with DM). ROS levels were determined as MDA (Malondialdehyde) and antioxidant status as plasma total antioxidant capacity (TAC), vitamin C and erythrocyte Superoxide dismutase (SOD) and catalase activity. RESULTS: There was significant increase in MDA levels in all the patient groups compared with healthy controls (p<0.05). The decrease in TAC, Vitamin C and SOD levels among CP with DM patients as compared to controls was highly significant (p<0.01). There was a positive correlation between the probing pocket depth and MDA levels among periodontitis patients with diabetes (r=0.566, p=0.003). CONCLUSION: There is increased oxidative stress in chronic periodontitis with and without type 2 diabetes indicating a common factor involvement in tissue damage. More severe tissue destruction in periodontitis is associated with excessive ROS generation which is positively correlated in type 2 diabetic subjects.

Paraoxonase Activity and Lipid Profile in Paediatric Nephrotic Syndrome: A Cross-sectional Study.

INTRODUCTION: Dyslipidaemia of Nephrotic Syndrome (NS) is known to be linked to oxidative reactions and atherosclerosis. Paraoxonase (PON1) has been implicated in the prevention of Low Density Lipoprotein (LDL) lipid peroxidation and also degrades biologically active oxidised lipids in lipoprotein. AIM: The present study was taken up to assess PON1 levels in paediatric nephrotic syndrome and also to see if any correlation exists between lipid parameters and PON1. MATERIALS AND METHODS: This study consists of Group 1 with 40 cases of NS in the age group of 2-14 years and Group 2 with 40 age and sex matched healthy controls. Lipid profile and paraoxonase activity was measured in serum samples of both the groups. RESULTS: Statistical analysis by student's t-test showed that the mean levels of Total Cholesterol, Trigylycerides, LDL, and VLDL were significantly increased in Group 1 when compared to Group 2 (p <0.001). The mean levels of HDL were similar in both groups. The levels of PON1 were significantly lowered in Group 1 when compared to Group 2. Correlation studies showed no significant correlation between lipid profile and PON1. CONCLUSION: Cases have atherosclerotic dyslipidaemia and significantly decreased PON1 activity. Decreased PON1 may lead to increased oxidation of LDL accelerating the process of atherosclerosis.

Cell surface interaction of annexin A2 and galectin-3 modulates epidermal growth factor receptor signaling in Her-2 negative breast cancer cells.

Overexpression and activation of tyrosine kinase receptors like EGFR and Src regulate the progression and metastasis of Her-2 negative breast cancer. Recently we have reported the role of cell membrane interaction of phospholipid-binding protein annexin A2 (AnxA2) and EGFR in regulating cellular signaling in the activation of angiogenesis, matrix degradation, invasion, and cancer metastasis. Beta-galactoside-specific animal lectin galectin-3 is an apoptosis inhibitor, and cell surface-associated extracellular galectin-3 also has a role in cell migration, cancer progression, and metastasis. Similar expression pattern and membrane co-localization of these two proteins made us to hypothesize in the current study that galectin-3 and AnxA2 interaction is critical for Her-2 negative breast cancer progression. By various experimental analyses, we confirm that glycosylated AnxA2 at the membrane surface interacts with galectin-3. N-linked glycosylation inhibitor tunicamycin treatment convincingly blocked AnxA2 membrane translocation and its association with galectin-3. To analyze whether this interaction has any functional relevance, we tried to dissociate this interaction with purified plant lectin from chickpea (Cicer arietinum agglutinin). This highly specific 30 kDa plant lectin could dissociate AnxA2 from endogenous lectin galectin-3 interaction at the cell surface. This dissociation could down-regulate Bcl-2 family proteins, cell proliferation, and migration simultaneously triggering cell apoptosis. Targeting this interaction of membrane surface glycoprotein and its animal lectin in Her-2 negative breast cancer may be of therapeutic value.

Resistin levels in gingival crevicular fluid of patients with chronic periodontitis and type 2 diabetes mellitus.

BACKGROUND: Resistin is associated with local and systemic inflammatory conditions with a direct correlation with type 2 diabetes mellitus (T2DM). The aim of this clinico-biochemical study is to estimate and compare the levels of resistin in the gingival crevicular fluid (GCF) in health, chronic periodontitis (CP), and T2DM. METHODS: Sixty patients (aged >35 years) who participated in this study were divided into four groups of 15 patients each: healthy individuals (group 1), patients with CP (group 2), patients with T2DM (group 3), and patients with T2DM and CP (group 4). The parameters assessed included plaque index (PI), gingival index (GI), probing depth (PD), periodontal index, body mass index, random blood sugar (RBS), and glycated hemoglobin (HbA1c). GCF (4 µL) was collected and analyzed for resistin levels using an enzyme-linked immunosorbent assay. RESULTS: Resistin was detected in the GCF of all patients. A significant difference was observed in GCF resistin concentrations from group 1 versus group 2 (P = 0.0093), group 3 (P = 0.0341), and group 4 (P = 0.0002); in group 2 versus group 4 (P = 0.0032); and in group 3 versus group 4 (P = 0.0008). When all the samples were analyzed together, GCF resistin levels positively correlated with GI, PD, PI, RBS, and HbA1c and were predictable with PD and HbA1c. CONCLUSIONS: Resistin levels are increased in CP and T2DM. Hence, GCF resistin levels may be considered as a potential inflammatory marker for periodontitis with T2DM.

A short-term evaluation of the relationship between plasma ascorbic acid levels and periodontal disease in systemically healthy and type 2 diabetes mellitus subjects.

BACKGROUND: Deficient ascorbic acid levels (AALs) and Type 2 diabetes mellitus (T2DM) are associated with periodontal disease. This study evaluated the relationship between plasma AAL and periodontitis in systemically healthy and T2DM subjects, which to the best of our knowledge is being reported for the first time. METHODS: One hundred twenty subjects were categorized into four groups of 30 each as group 1: without periodontal disease; group 2: chronic gingivitis; group 3: chronic periodontitis, and group 4: chronic periodontitis and freshly diagnosed T2DM. Plaque index (PlI), sulcus bleeding index (SBI), and probing pocket depths (PPDs) were evaluated. Venous blood was evaluated for plasma AAL spectrophotometrically. Randomized subjects were subgrouped within groups 2-4, to receive either scaling and root planing (SRP) with dietary supplementation (450 mg) of ascorbic acid (AA) for two weeks or only SRP. After two weeks, the clinical parameters were reassessed. Tukey's multiple post hoc procedures and paired t test were used with the level of statistical significance adjusted to p ≤ .05. RESULTS: AAL plasma levels were significantly greater in group 1 than in group 2 (p = .0007) and in group 4 (p = .0003). A significant reduction in the SBI was seen in the subgroups that received dietary supplementation of vitamin C within group 2 (p = .0012) and group 4 (p = .036). CONCLUSIONS: Plasma AAL is below the normal range in systemically healthy subjects with gingivitis and diabetics with periodontitis. Dietary AA supplementation with SRP improves the SBI in subjects with gingivitis and diabetics with periodontitis.

Morpho-anatomy of Solanum pseudocapsicum

Morpho-anatomical features in leaves, stems and unripe fruits of Solanum pseudocapsicum L., Solanaceae, were investigated by histological methods. Anatomically the plant may be characterised by the presence of uniseriate trichomes, anomocytic stomata, calcium oxalate needles in leaves while presence of oval to circular compound starch grains, angular vessels, vertically upright, uni-biseriate rays and intraxylary phloem with differentiation of internal cambium abutting marginal pith cells and protoxylem in transverse view. Development of distinct internal cambium may be considered as a characteristic feature for S. pseudocapsicum. Intraxylary secondary phloem was composed of sieve tube elements, companion cells and axial parenchyma cells.

Hospital based preliminary study on osteoporosis in postmenopausal women.

The awareness of osteoporosis has grown world wide in recent years. This silently progressing metabolic bone disease is widely prevalent in India, and osteoporotic fractures are a common cause of morbidity and mortality in adult Indian men and women. Rapid bone loss occurs in postmenopausal women due to hormonal factors which lead to increased risk of fractures. Biochemical markers of bone metabolism are used to assess skeletal turnover. A cross-sectional study of 150 pre- and post menopausal women was carried out at S.D.M College of Medical Sciences and Hospital, Dharwad, during the period of May 2005 to September 2005. The study group consisted of 75 Premenopausal women in the age group of 25-45 years and 75 Postmenopausal women in the age group of 46-65 years. Bone formation markers (Total Calcium, lonised calcium, Phosphorus, Alkaline phosphatase), and bone resorption markers (Urinary Hydroxyproline) were analysed in pre and post menopausal women. Bone formation markers, Total and lonised calcium were significantly decreased (p<0.001) and Alkaline phosphatase was significantly increased (p<0.001) in postmenopausal women compared to premenopausal women. Bone resorption markers, Urinary hydroxyproline excretion was significantly increased (p<0.001) in postmenopausal women. The results from this study suggest that simple, easy, common biochemical markers can still be used to assess the bone turnover in postmenopausal women and hence their risk of developing osteoporosis and fractures.
