    Behçet’s disease is a systemic disease which may involve various organs. We describe a case of a patient diagnosed as pleuropericardial involvement of Behçet’s disease. A 30-year-old woman visited our clinic presented with left pleuritic chest pain for s days. She had been diagnosed as Behçet’s disease and admitted to our clinic due to pericardial and pleural effusion repeatedly in past two years. In the previous studies, effusion analysis revealed to be lympho-dominant exudate with high adenosine deaminase level. Acid-fast bacilli (AFB) culture and polymerase chain reaction (PCR) for mycobacterial tuberculosis (M.TB) were negative in the pericardial tissue, and pathologic finding showed mild endothelitis with micro-thrombi formation in the lumen. The patient had been treated with antituberculous medication for a year. In the current admission, chest computed tomography (CT) again showed left pleural effusion without other significant lesion. Pleural fluid analysis was similar with the previous study. Video-assisted thoracoscopic pleural biopsy was performed to obtain the definite diagnosis. Pathology confirmed the diagnosis as pleuropericardial involvement of Behçet’s disease, and we treated the patient with oral steroid in the out-patient department. Pleuropericardial involvement of Behçet’s disease may mimic TB pleurisy or pericarditis due to high adenosine deaminase (ADA) level in effusion analysis. Clinicians should keep in mind that Behçet’s disease may manifest as pleural or pericardial effusion, and pathologic confirmation could be helpful for the definite diagnosis. PMID:27499994

    Shock as an inadequate tissue perfusion is one of the frequent causes of death in trauma patients. In this context, there are various reasons for hemodynamic instability and shock including hypovolemic (hemorrhagic), obstructive (cardiac tamponade, tension pneumothorax), cardiogenic, neurogenic, and rarely septic. In the present report, a 30-year-old trauma patient with full clinical signs and symptoms of shock referred while had unknown origin; it was finally recognized as anaphylactic shock. PMID:26495357

    Purpose. To report a case of unilateral optic neuritis following Measles-Mumps-Rubella (MMR) vaccination. Methods. A 30-year-old female developed unilateral optic neuritis five days after a Measles-Mumps-Rubella (MMR) booster vaccination. The patient displayed unilateral involvement, with severe visual loss. However, visual acuity improved significantly after four days of intravenous steroid therapy with 500 mg/day of methylprednisolone. Conclusions. Optic neuritis is one of the rare complications associated with the mumps, measles, and rubella vaccine. It may be a toxic reaction to the nonviral component of the vaccine, but the exact etiology is unknown. Postvaccination neuritis is generally bilateral and usually affects children. In adults, unilateral optic neuritis is usually correlated with multiple sclerosis (MS). PMID:27195163

    A growing body of evidence has implicated allergens derived from cockroaches as an important environmental factor that may aggravate asthma in sensitized persons. We present the case of a 30-year-old man with asthma and a cockroach allergy. Allergy skin testing confirmed hypersensitivity to cockroach extract, and a home visit revealed visual evidence of infestation and the presence of Bla g 1 German cockroach allergen in vacuumed dust. As is typical of patients with a cockroach allergy and asthma, multiple factors in addition to cockroach allergen appeared to aggravate the patient's asthma. A multimodality therapeutic regimen, which included medications as well as cleaning of the home, integrated pest management, and professional application of chemical controls, resulted in substantial clinical improvement. The pathophysiology, epidemiology, and clinical features of cockroach-allergic asthma are reviewed, and an approach to diagnosis and management is suggested. Images Figure 1 Figure 2 PMID:10064555

    Objectives The purpose of this case report is to describe the chiropractic management of a patient presenting with right arm paralysis and a diagnosis of Parsonage-Turner syndrome. Clinical Features After receiving nerve entrapment release surgery, a 30-year-old man presented with a right arm contracture, atrophy, and weakness with general paralysis of the forearm and index finger of 6 weeks' duration. Intervention and Outcome The patient was provided chiropractic care that included high-velocity/low-amplitude spinal manipulation based upon applied kinesiology manual muscle testing, soft tissue trigger point therapy, exercises, and stretches. The patient demonstrated improvement in range of motion after the first treatment session. By the eighth treatment, he was able to fully straighten his arm. Three years later, the patient reported that he was able to do mountain climbing and that his arm was fully functional and pain-free. Conclusion For this patient, chiropractic care seemed to be successful in relieving his right arm paralysis and restoring normal arm movement. PMID:22654689

    The contamination from a 30-year-old radioactive liquid drain field was assessed for movement in the subsurface and potential risks to humans. This assessment included determining field concentrations of cesium 137 (137Cs) and other inorganic contaminants and modeling of the flow and transport of the liquid waste that was sent to the drain field. The field investigation detected no contamination deeper than 15 feet (4.6 m) from the bottom of the drain field. Prediction of the water content of the vadose zone showed no saturated conditions for times greater than 10 years after the known infiltration. Sensitivity analysis of the modeling parameters showed the equilibrium sorption coefficient to be the most important factor in predicting the contaminant plumes. Calibration of modeling results with field data gave a 137Cs sorption coefficient that is within the range of values found in the literature. The risk assessment for the site showed that the contamination poses no significant risk to human health.

    This work examines where 18- to 30-year-old college students seek health information on the Internet and how they determine site and message credibility. Using a qualitative methodology, five focus groups were conducted with 18- to 30-year-old college students, and transcripts were analyzed with MaxQDA text analysis software. The study revealed that 18- to 30-year-old college students have Internet health information source preferences, reasons for seeking health information on the Internet, and message design factors that improve their perception of site and message credibility. We conclude that the Internet and social media show great promise as effective health communication channels for 18- to 30-year-old college students and confirm that preferred Internet/social media sites can be utilized by health educators to present important risk management/disease prevention information to 18- to 30-year-old college students. In addition, message design factors can lend credibility to both sites and the health information delivered there. PMID:25887107

    Perceptual narrowing in the visual, auditory, and multisensory domains has its developmental origins in infancy. The present study shows that experimentally induced experience can reverse the effects of perceptual narrowing on infants’ visual recognition memory of other-race faces. Caucasian 8- to 10-month-olds who could not discriminate between novel and familiarized Asian faces at the beginning of testing were given brief daily experience with Asian female faces in the experimental condition and Caucasian female faces in the control condition. At the end of three weeks, only infants who received daily experience with Asian females showed above-chance recognition of novel Asian female and male faces. Further, infants in the experimental condition showed greater efficiency in learning novel Asian females compared to infants in the control condition. Thus, visual experience with a novel stimulus category can reverse the effects of perceptual narrowing in infancy via improved stimulus recognition and encoding. PMID:22625845

    Hepatitis C virus (HCV) infection incidence among 18- to 30-year-olds is increasing and guidelines recommend treatment of active injection drug users to limit transmission. We aimed to : measure linkage to HCV care among 18- to 30-year-olds and identify factors associated with linkage; compare linkage among 18- to 30-year-olds to that of patients >30 years. We used the electronic medical record at an urban safety net hospital to create a retrospective cohort with reactive HCV antibody between 2005 and 2010. We report seroprevalence and demographics of seropositive patients, and used multivariable logistic regression to identify factors associated with linkage to HCV care. We defined linkage as having evidence of HCV RNA testing after reactive antibody. Thirty two thousand four hundred and eighteen individuals were tested, including 8873 between 18 and 30 years. The seropositivity rate among those ages 18-30 was 10%. In multivariate analysis, among those 18-30, diagnosis location (Outpatient vs Inpatient/ED) (OR 1.78, 95% CI 1.28-2.49) and number of visits after diagnosis (OR 5.30, 95% CI 3.91-7.19) were associated with higher odds of linking to care. When we compared linkage in patients ages 18-30 to that among those older than 30, patients in the 18-30 years age group were more likely to link to HCV care than those in the older cohort even when controlling for gender, ethnicity, socioeconomic status, birthplace, diagnosis location and duration of follow-up. Eighteen- to 30-year-olds are more likely to link to HCV care than their older counterparts. During the interferon-free treatment era, there is an opportunity to prevent further HCV transmission in this population. PMID:26572798

    Coronary artery dissection is an infrequent cause of acute coronary syndrome in the general population. There is, however, a greater incidence of spontaneous coronary artery dissection (SCAD) in young women, especially in the peripartum period. However, the majority of cases have favorable outcomes with medical management or percutaneous coronary intervention; coronary artery bypass grafting (CABG) and transplantation are utilized in severe cases. This case is a one of a 30-year-old postpartum female with multivessel SCAD requiring CABG with subsequent biventricular failure and inability to wean from bypass. We believe this is the first reported case in which venoarterial extracorporeal membrane oxygenation (VA-ECMO) was used in the management of biventricular heart failure in a postpartum patient with SCAD.

    We have studied the viability of targeted molecular screening for the identification of female patients with hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome. Affected patients harbor a germ-line heterozygous mutation of the fumarate hydratase (FH) gene. Clinically, some patients present with aggressive renal cell carcinoma. Concerning women, in almost all cases, this is preceded by symptomatic uterine leiomyoma. We aimed to identify women operated on for symptomatic leiomyoma by the age of 30. Archived paraffin-embedded leiomyoma tissue was tested for the FH gene mutation in 14 cases. Two patients with multiple leiomyomas and with the confirmed germ-line mutations c.1433_1434dupAAA, p.(Lys477dup) and c.953A>T, p.(His318Leu) were identified and enrolled in a surveillance program. Statistically significant correlation between the presence of multiple uterine leiomyomas (more than seven in our experience) and the FH gene mutation was found. The immunohistochemical expression pattern, of simultaneous FH absence and S-(2-succino)cysteine (2SC) positivity, correlated with the results of the molecular genetic study in only one case. The histomorphologically simultaneous detection of enlarged nucleoli with a clear halo of leiomyocyte nuclei, their fibrillary cytoplasm, the presence of eosinophilic globules, and staghorn vessels proved to be only a partially sensitive indicator of HLRCC-associated leiomyoma and fully correlated with immunohistochemistry and molecular genetic study only in one case. Molecular genetic testing is presently the only reliable diagnostic tool able to identify HLRCC patients. The sensitivity and specificity of the presence of multiple leiomyomas in women with the FH gene mutation who are younger than 30 years old should be confirmed in larger scale studies. The applied targeted molecular screening protocol proved to be effective, resulting in identification of two positive patients out of fourteen tested individuals. PMID:25985877

    Fetal wound healing occurs rapidly and without scar formation early in gestation, but the mechanisms underlying this scarless healing are poorly understood. This study explores the phenotypic and functional modulation of 20-30 year old dermal fibroblasts by mid- and late-gestational keratinocytes (KCs) in vitro. Human KCs of different gestational ages were isolated, characterized, and co-cultured with human 20-30 year old fibroblasts. Gene expression and protein levels of TGF-β family members, precollagen, collagen, matrix metalloproteinases (MMPs), and the tissue inhibitors of metalloproteinases (TIMPs) were measured in the fibroblasts. Mid-gestational KCs promoted faster proliferation and migration of fibroblasts than late-gestational KCs. Additionally, significant differences in gene expression and protein levels of some markers were observed in fibroblasts co-cultured with mid- or late-gestational KCs. Fibroblasts co-cultured with mid-gestational KCs for 48 h exhibited downregulated gene expression of precollagen 1, collagen 1, TGF-β1, TGF-β2, TIMP-2 and TIMP-3, while precollagen 3, collagen 3, TGF-β3, and MMP-1, -2, -3, -9 and -14 were upregulated. In contrast, late-gestational KCs exhibited downregulated TIMP-1, TIMP-2 and TIMP-3 levels, while collagen 1, TGF-β2, TGF-β3, and MMP-2, -3, -9 and -14 were upregulated. Moreover, statistically significant differences in expression levels of precollagen 1, precollagen 3, collagen 1, TGF-β1, -β2, and -β3, MMP-1, -3 and MMP-14, TIMP-1 and TIMP-2 were found between fibroblasts co-cultured with mid- and late-gestational KCs. Furthermore, cytokine levels of IL-1a and HB-EGF were found to be statistically different between conditioned medium from mid- and late-gestational KCs. Therefore, the gestational age of KCs appears to have an important effect on scarless wound healing in the human fetus. PMID:25599870

    Osteoporosis and osteoporotic fractures represent a substantial health burden, and predominantly affect the elderly. Younger generations may also develop these conditions because of various predisposing conditions, including primary hyperparathyroidism. However, little information is available regarding early skeletal manifestations of primary hyperparathyroidism.A 30-year-old Japanese male presented with pain in his left wrist, and was diagnosed with a distal radius fracture. During surgery, we noticed decreased bone strength of the fracture site. Further investigation found osteoporosis and primary hyperparathyroidism owing to a solitary parathyroid adenoma, which was resected without significant complications. History revealed that the patient suffered a metacarpal bone fracture of his right fifth bone 6 months earlier. Although serial x-rays at that time had shown rapidly developed cortical bone erosion around the fractured finger, the possibility of primary hyperparathyroidism was overlooked because of poor awareness of the condition, leading to a 6-month delay in the diagnosis of primary hyperparathyroidism.Clinicians should be aware that finger fractures may be an early skeletal manifestation of primary hyperparathyroidism that can help achieve a prompt diagnosis of the condition, especially when they occur in young adults in the absence of major trauma.

    To determine the timing of peak bone mass and density, we conducted a cross-sectional study of bone mass measurements in 265 premenopausal Caucasian females, aged 8-50 yr. Bone mass and bone mineral density were measured using dual X-ray absorptiometry and single-photon absorptiometry at the spine (anteroposterior, lateral), proximal femur, radius shaft, distal forearm, and the whole body. Bone mass parameters were analyzed using a quadratic regression model and segmented regression models with quadratic-quadratic or quadratic-linear form. The results show that most of the bone mass at multiple skeletal locations will be accumulated by late adolescence. This is particularly notable for bone mineral density of the proximal femur and the vertebral body. Bone mass of the other regions of interest is either no different in women between the age of 18 yr and the menopause or it is maximal in 50-yr-old women, indicating slow but permanent bone accumulation continuing at some sites up to the time of menopause. This gain in bone mass in premenopausal adult women is probably the result of continuous periosteal expansion with age. Since rapid skeletal mineral acquisition at all sites occurs relatively early in life, the exogenous factors which might optimize peak bone mass need to be more precisely identified and characterized.

    Background High concentrations of pro-inflammatory cytokines have been previously observed in the genital fluids of women enrolled in microbicide trials and may explain observed increased HIV transmission in some of these trials. Although the longitudinal nature of these studies allows within-subject comparisons of post-product levels to baseline levels, the fact that the physiologic variations of these cytokines and other markers of immune activation are not fully defined in different populations, makes it difficult to assess changes that can be directly attributed to microbicide use as opposed to other biological and behavioural factors. Methods Cervicovaginal lavage samples were collected from 30 healthy Caucasian and assayed for concentrations of ten cytokines/chemokines, total protein content and two antimicrobial proteins using a multiplex immunoassay and ELISA. Cellular markers were characterized by flow cytometry on mononuclear cells collected from the endocervix using flocked swabs. Bacterial quantification was performed using quantitative PCR. Results Ectopy, menstrual cycle phase, prostate-specific antigen and presence of leucocytes in endocervical cells' supernatant were associated with the concentrations of cyto-/chemokines in cervicovaginal secretions. Approximately 3% of endocervical cells collected were monocytes of which a median of 52% (SD  = 17) expressed both CD4 and CCR5 markers. Approximately 1% of the total cells were T-cells with a median of 61% (SD  = 10) CD4 and CCR5 expression. Around 5% of the monocytes and 16% of the T-cells expressed the immune activation marker HLA-DR. Higher percentages of T-cells were associated with greater quantities of IL-1RA, GM-CSF and elafin. Conclusion We demonstrate the presence of selected soluble and cellular immune activation markers and identify their predictors in the female genital tract of healthy women. Future clinical trials should consider ectopy, sexual activity, menstrual cycle phase and

    Objective The objective of this study was to compare the skeletal, dental and soft tissue characteristics of Caucasian and Afro-Caucasian Brazilian subjects with normal occlusion and to evaluate sexual dimorphism within the groups. Material and Methods The sample comprised lateral cephalograms of untreated normal occlusion subjects, divided into 2 groups. Group 1 included 40 Caucasian subjects (20 of each sex), with a mean age of 13.02 years; group 2 included 40 Afro-Caucasian subjects (20 of each sex), with a mean age of 13.02 years. Groups 1 and 2 and males and females within each group were compared with t tests. Results Afro-Caucasian subjects presented greater maxillary protrusion, smaller upper anterior face height and lower posterior face height, larger upper posterior face height, greater maxillary and mandibular dentoalveolar protrusion as well as soft tissue protrusion than Caucasian subjects. The Afro-Caucasian female subjects had less mandibular protrusion and smaller total posterior facial height and upper posterior facial height than males. Conclusions Brazilian Afro-Caucasian subjects have greater dentoalveolar and soft tissue protrusion than Brazilian Caucasian subjects, with slight sexual dimorphism in some variables. PMID:21552712

    Digital and palmar dermatoglyphics were collected from 360 male and 360 female seven year old Caucasians from the greater Boston area. All participants were screened and found to be free of minor anomalies or chronic diseases. All individuals with I. Q. scores below 70 were also excluded. The results were presented in such a way as to give information on bilateral symmetry as well as overall frequencies of the various dermatoglyphic features. The results were compared with those of the corresponding sample of seven year old normal male and female Negroes of the accompanying report. A review of the distribution of the dermatoglyphic features in different Caucasian populations has also been presented and the overall dermatoglyphics of the Caucasians were discussed in reference to the distribution of the same features in the other major "racial" groups. The method of collection and selection of the subjects, described in the text, makes this set of data unique and one of the most suitable for use as controls in studying the dermatoglyphics of the individuals with diseases or congenital anomalies.

    Computational anthropomorphic human phantoms are useful tools developed for the calculation of absorbed or equivalent dose to radiosensitive organs and tissues of the human body. The problem is, however, that, strictly speaking, the results can be applied only to a person who has the same anatomy as the phantom, while for a person with different body mass and/or standing height the data could be wrong. In order to improve this situation for many areas in radiological protection, this study developed 18 anthropometric standing adult human phantoms, nine models per gender, as a function of the 10th, 50th and 90th mass and height percentiles of Caucasian populations. The anthropometric target parameters for body mass, standing height and other body measures were extracted from PeopleSize, a well-known software package used in the area of ergonomics. The phantoms were developed based on the assumption of a constant body-mass index for a given mass percentile and for different heights. For a given height, increase or decrease of body mass was considered to reflect mainly the change of subcutaneous adipose tissue mass, i.e. that organ masses were not changed. Organ mass scaling as a function of height was based on information extracted from autopsy data. The methods used here were compared with those used in other studies, anatomically as well as dosimetrically. For external exposure, the results show that equivalent dose decreases with increasing body mass for organs and tissues located below the subcutaneous adipose tissue layer, such as liver, colon, stomach, etc, while for organs located at the surface, such as breasts, testes and skin, the equivalent dose increases or remains constant with increasing body mass due to weak attenuation and more scatter radiation caused by the increasing adipose tissue mass. Changes of standing height have little influence on the equivalent dose to organs and tissues from external exposure. Specific absorbed fractions (SAFs) have also

    In order to better define the role of pharmacokinetic variation in reported cross-ethnic differences in dosing patterns of some psychoactive drugs, single dose kinetics of the tricyclic antidepressant desipramine (DMI) were studied in 14 Chinese and 16 Caucasian healthy volunteers. DMI and 2-OH-DMI concentrations were assayed with h.p.l.c. in serial plasma and 24 h urine samples over 5 days following an oral 100 mg dose of DMI. Mean total clearance of DMI ( CLDMI ) from plasma was significantly (P less than 0.05) higher in the Caucasians (123 +/- 57 l/h) than in the Chinese (73.5 +/- 38.8 l/h). There was no significant difference in the apparent clearance of DMI by hydroxylation, fraction of dose metabolized to the hydroxy metabolite, DMI t1/2 or plasma protein binding between the two groups. Trimodal distribution of CLDMI was found, with 4/14 (29%) Chinese demonstrating slow CL (less than 33 l/h) and 4/16 (25%) Caucasians rapid CL (greater than 195 l/h). Correcting CL values for the greater mean weight of the Caucasians did not alter the pattern of distribution. CLDMI did not correlate with body weight. Although environmental factors cannot be ruled out, these results are consistent with genetically based differences in hepatic metabolism, probably affecting pathways in addition to hydroxylation, and suggest that 30% of Orientals would be at risk for toxicity from routine doses of tricyclics or similarly metabolized drugs.

    Young adults with hemophilia face unique challenges during the transition to adulthood, including issues associated with switching from pediatric to adult hematology care, building mature interpersonal relationships, and establishing an independent career with an assurance of medical insurance coverage. A greater understanding of these challenges is essential for developing effective strategies to address the specific needs of this population. These challenges may be differentiated from those of older adults with hemophilia in large part because of more extensive childhood prophylaxis and safer factor products, resulting in fewer joint problems and lower rates of HIV and HCV infections. This analysis of the changing nature and unmet needs of today's young adults entering into adult hemophilia treatment centers, as well as potential strategies for optimally addressing these needs, was developed following roundtable discussions between patients, caregivers, hematologists, and other health care professionals participating in comprehensive care. Challenges identified among young adults with hemophilia include psychosocial issues related to maturity, personal responsibility, and increased independence, as well as concerns regarding when and with whom to share information about one's hemophilia, limited awareness of educational and financial resources, and a low perceived value of regular hematology care. The initiatives proposed herein highlight important opportunities for health care professionals at pediatric and adult hemophilia treatment centers, as well as national organizations, community groups, and career counselors, to address key unmet needs of this patient population.

    Sinus rhythm; an atrial premature complex; sagging ST-segments, low T-waves, and prominent U-waves suggesting hypokalemia. The ST-T and U-wave changes described above are characteristic of hypokalemia. When the serum potassium level is between 3.0 and 3.5 mEq/L, one or more of the findings may be present. All three are common when the serum potassium level is below 2.5 mEq/L. At the lowest serum potassium levels the T-wave becomes a notch on the upstroke of a giant U-wave, as occurs here in the ECG of this woman with a serum potassium of 1.7 mEq/L.1,2 This configuration is occasionally mistaken for the ST-segment depression and long QT interval of myocardial ischemia.3 Atrial premature complexes are common with hypokalemia, and atrial fibrillation may occur. This patient's potassium was repleted, and the following day her ECG was essentially normal (Figure 2) and virtually unchanged from an ECG recorded two years earlier. PMID:27159459

    The Caucasus lies between the Black Sea and the Sea of Azov on the west and the Caspian Sea on the east. The main morphological elements of the Caucasus are the mountain ranges of Greater and Lesser Caucasus, which are divided by the Rioni (Colchis) and Kura intermontane troughs and the pre-Caucasian plain and Araks Depression. The tectonic features of the region result from its position between the Eurasian and Africa-Arabian plates. Two tectonic units of the highest order are distinguished within its limits, the young Scythian platform in the north and the Alpine fold belt in the south. Oil and gas deposits have been found only in the lowlands of the Caucasus, in the pre-Caucasian foreland, and within the Transcaucasian intermontane depressions. The North Caucasian province is made up of the Scythian platform and the marginal troughs of the Alpine Greater Caucasus. Oil and gas accumulations occur at all levels within the sedimentary cover from Triassic the Neogene. In the South Caspian oil and gas subprovince, oil and gas occurs within reservoirs range in age from Late Cretaceous to the Apsheronian stage of the Neogene. The Black Sea subprovince comprises the northwestern part of the sea and the western part of Georgia. The bulk of the explored oil reserves lies within the Neogene and Upper Cretaceous units. The potential in this region is associated with Jurassic terrigenous, Upper Cretaceous carbonate, and Paleogene terrigenous sediments.

    In this exploratory study, we examined differences in the legal characteristics of Caucasian and African-American female offenders (n = 122) who were diverted into substance abuse treatment, to identify any racial disparities. We also examined the differences between groups in demographics and in substance abuse, family, and violence histories. In terms of legal characteristics, the results showed that African-American female offenders were significantly more likely to have been incarcerated at the time of their substance dependency evaluation than were Caucasian female offenders. Also, African-American women were more likely to have served 13 months for the current legal charge in comparison to the 4 months served by Caucasian women, although no differences were found between groups in the severity of the current legal charge. Comparison of demographics and substance abuse, family, and violence histories indicated that African-American women were more likely to be undereducated, crack cocaine dependent, and overly exposed to violence. Overall, the sample of female offenders evidenced severe substance dependency problems, a strong need for inpatient substance abuse treatment, and chronic legal and social difficulties. Implications of these findings are discussed in relation to unbalanced sentencing policies and increasing awareness of the treatment needs of this unique population. PMID:21389168

    To test for demographic and clinical differences between Caucasian and South Asian patients with psoriatic arthritis (PsA) living in the same environment and for differences between sexes. The demographic characteristics of patients attending outpatient clinics were obtained using a semi-structured questionnaire. Clinical parameters included disease activity (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), erythrocyte sedimentation rate (ESR), C-reactive protein), function (Bath Ankylosing Spondylitis Functional Index (BASFI)) and visual analogue scale (VAS) scores for well-being and night pain (10 cm, where 10 = worst possible response). The first symptom experienced at disease onset and the main symptoms during the disease course were recorded in the questionnaire. A total of 217 patents were assessed of whom 151 were Caucasians and 66 were Asians. South Asian patients were significantly younger [(mean) 45.9 years [(SD)(±11.4)] for Asians and 53.1 years (±14.2) for Caucasians (p < 0.005)] and were diagnosed at an earlier age [40.7 years (±11.7) for Asians and 46.7 years (±15.8) for Caucasians (p < 0.05)] compared to Caucasians patients. Asian females with PsA had worse disease in terms of activity (ESR = 23.9 mmHg/h; BASDAI = 6.7), function (BASFI = 5.5), night pain (7.1 on VAS) and well-being (6.6 on VAS) compared with Asian males (13.2 mmHg/h, 5.3, 3.6, 4.1, 4.6, respectively) or Caucasian males and females (15.8 mmHg/h, 5.9, 5.3, 5.4, 5.4; 18.9 mmHg/h, 6.1, 6.1, 5.3, 5.8, respectively). There were no significant differences in symptoms at disease onset or the main symptoms during the disease course between Caucasian and Asian patients, although there was a trend towards more frequent enthesitis in Asian females during the course of disease suggested by pain with pressure compared to Asian males. South Asian patients may develop PsA earlier in life than Caucasian patients do, but their clinical characteristics are generally similar. Asian

  1. Lipoprotein Profiles in Class III Obese Caucasian and African American Women with Nonalcoholic Fatty Liver Disease

    Triglyceride content in the liver is regulated by the uptake, production and elimination of lipoproteins, and derangements in these processes contribute to nonalcoholic fatty liver disease (NAFLD). Previous studies show a direct relationship between intrahepatic fat and production of apolipoprotein B100 (apoB100) containing particles, VLDL and LDL, but little consensus exists regarding changes in lipoprotein production in the development of simple steatosis (SS) versus nonalcoholic steatohepatitis (NASH). Further, ethnic variations in lipoproteins among SS and NASH are unknown as is how such variations might contribute to the differential prevalence of disease among Caucasians versus African Americans. In this study, we assessed plasma lipoprotein profiles by nuclear magnetic resonance (NMR) spectroscopy in 70 non-diabetic class III obese females recruited from the surgical weight loss clinic. Of these, 51 females were stratified by biopsy-staged NAFLD severity (histologically normal, SS, or NASH). NASH females displayed increased circulating triglycerides and increased VLDL particle number and size relative to those with histologically normal livers, while total and large LDL concentration decreased in SS versus NASH and correlated with increased insulin resistance (via HOMA2-IR). When Caucasian women were examined alone (n = 41), VLDL and triglycerides increased between normal and SS, while total LDL and apoB100 decreased between SS and NASH along with increased insulin resistance. Compared to Caucasians with SS, African American women with SS displayed reduced triglycerides, VLDL, and small LDL and a more favorable small to large HDL ratio despite having increased BMI and HOMA2-IR. These findings suggest that ApoB100 and lipoprotein subclass particle number and size can delineate steatosis from NASH in obese Caucasian females, but should be interpreted with caution in other ethnicities as African Americans with SS display relatively improved lipoprotein profiles

    We have previously shown evidence of strong sex-biased genetic blending in the founding and ongoing history of the Brazilian population, with the African and Amerindian contribution being highest from maternal lineages (as measured by mitochondrial DNA) and the European contribution foremost from paternal lineages (estimated from Y-chromosome haplogroups). The same phenomenon has been observed in several other Latin American countries, suggesting that it might constitute a universal characteristic of the Iberian colonization of the Americas. However, it has also recently been detected in the Black population of the United States. We thus wondered if the same could be observed in American Caucasians. To answer that question, we retrieved 1387 hypervariable I Caucasian mitochondrial DNA sequences from the FBI population database and established their haplogroups and continental geographical sources. In sharp contrast with the situation of the Caucasian population of Latin American countries, only 3.1% of the American Caucasian sequences had African and/or Amerindian origin. To explain this discrepancy we propose that the finding of elevated genomic contributions from European males and Amerindian or African females depends not only on the occurrence of directional mating, but also on the "racial" categorization of the children born from these relations. In this respect, social practices in Latin America and in the United States diverge considerably; in the former socially significant "races" are normally designated according to physical appearance, while in the latter descent appears to be the most important factor.

    A 30-year-old, right-handed female presented 2 weeks postpartum with acute-onset severe headache, vertigo, and vomiting. Initial neurologic examination illustrated lingual dysarthria, horizontal nystagmus, right dysmetria on finger-to-nose testing, and weakness of the extremities. Magnetic resonance imaging showed a large, left lateral medullary infarction (Wallenberg syndrome) with cephalad extension into the ipsilateral pons as well as involvement of the left middle cerebellar peduncle. The patient was discharged 3 weeks later to an inpatient rehabilitation facility with gradual improvement of her symptoms. PMID:26500545

    The Atrial Fibrillation Follow-Up Investigation of Rhythm Management (AFFIRM) study concluded that rate control with anticoagulation was equivalent overall to rhythm control with cardioversion for long-term survival and that anticoagulation reduced the risk of stroke. We compared baseline and follow-up data for three ethnic groups: Caucasians (n=3,599), African Americans (n=265) and Hispanics (n=132). Caucasians were older and more likely male, African Americans were more likely female and hypertensive, and Hispanics had higher prevalence of cardiomyopathy. Survival was better for rate control than rhythm control in Caucasians, equivalent in African Americans and better for rhythm control in Hispanics. Outcomes may be influenced by differential baseline characteristics, but low numbers of African Americans and Hispanics warrant caution in data interpretation. BACKGROUND: The AFFIRM study compared a rate-control strategy to a rhythm-control strategy for the treatment of atrial fibrillation (AF) in patients at high risk for stroke or death. It concluded that the rhythm-control strategy offered no survival advantage, and it also confirmed the value of anticoagulation to prevent complications of AF. Data have not previously been available for specific racial ethnic populations. METHODS: We compared baseline and follow-up data for the patients randomized to rate-control versus rhythm-control in three population groups-Caucasian, African-American and Hispanic. RESULTS: Among 4,060 total patients, 3,599 were Caucasian, 265 were African-American and 132 were Hispanic. At baseline, Caucasians were older and had a higher percentage of males, normal ejection fractions, AF as their only cardiac diagnosis, a prior antiarrhythmic drug failure and less congestive heart failure. African Americans were more likely to be female, had more hypertension and qualified for the study with a first episode of AF, compared to Caucasians. Hispanics had more cardiomyopathy at baseline than

    Within dominant American culture, females often learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at (i.e., self-objectification), which can result in negative outcomes. Body surveillance (the indicator of self-objectification) has been found to predict concern with weight/shape in predominantly Caucasian samples, but research has not yet examined the potential reciprocal relations between body surveillance and weight/shape concern. Participants were 226 women attending a Midwestern university (70 self-identified as African American and 156 as Caucasian) who provided data at two time points, spaced about 5 months apart. Results revealed that downward spirals of body surveillance and weight/shape concern were apparent for the Caucasian but not the African American women. However, there was evidence that body surveillance helped account for change in weight/shape concern for the African American women. PMID:21596635

    Given that parenting practices have been linked to suicidal behavior in adolescence, examining the moderating effect of parenting styles on suicidal behavior early in development could offer potential insight into possible buffers as well as directions for suicide prevention and intervention later in adolescence. Hence, the moderating effects of parenting styles, including authoritarian, permissive, and features of authoritative parenting, on depressed and aggressive children's suicidal behavior, including ideation and attempts, were evaluated with young children (N = 172; 72% male, 28% female) ranging from 6 to 12 years of age. African American (69%) and Caucasian (31%) children admitted for acute psychiatric inpatient care completed standardized measures of suicidal behavior, depressive symptoms, and proactive and reaction aggression. Their parents also completed standardized measures of parental distress and parenting style. Hierarchical regression analyses revealed that, while statistically controlling for age and gender, children who endorsed more depressive symptoms or reactive aggression reported more current and past suicidal behavior than children who endorsed fewer depressive or aggressive symptoms. The significant positive relationship observed between depressive symptoms and childhood suicidal behavior, however, was attenuated by parental use of authoritarian parenting practices for African-American and older children but not for younger and Caucasian children. The ethnic/racial difference observed for the buffering effect of authoritarian parenting practices offers potential theoretical and clinical implications for conceptualizing the moderating effects of parenting styles on African-American and Caucasian children's suicidal behavior.

    The purpose of this study was to determine differences in reported alcohol use and depressive symptomatology among a sample of 524 African-American and Caucasian adolescents. Of specific interest was determining if ethnicity, gender, and age predicted severity of scores obtained on the Reynolds Adolescent Depression Scale (RADS) and Adolescent Drinking Index (ADI). Extreme groups were formed using upper (> 75%) and lower (< 25%) quartiles. Three other groups were formed using each instrument's normatively derived cutoff scores: depressed only (RADS > 77), heavy drinking (ADI > 16) and mixed (RADS > 77, ADI > 16). Several results were obtained. First, Caucasians obtained significantly higher scores on the ADI than African-Americans, although no differences were obtained for the RADS. Females scored higher on the RADS but lower on the ADI than males. In terms of extreme scores, females were less likely to belong to the severe depression group, while older adolescents in general and African-Americans in particular had a greater probability of belonging to the heavy-drinking group. Finally, using RADS and ADI cutoff scores, females were less likely than males to belong to the depression only group as were African-Americans. Older adolescents, in general, and African-Americans in particular had a greater probability of belonging to the mixed group than did their counterparts. PMID:15861619

    Background: Research regarding risk factors and prevalence of low bone mineral density (BMD) among African-American and Caucasian college-aged women are limited. The objective of this cross-sectional study was to determine if selected predictors of BMD in African-American and Caucasian college-aged women differ by race. Methods: A total of 101 local African-American (n=50) and Caucasian (n=51) females, ages 18 to 30 years, were in this study. All data were collected in the Bone Density and Body Composition Laboratory. BMD was measured using DXA technology. Race, family history of osteoporosis, BMI, current physical activity, osteoporosis knowledge, length of time on oral contraceptives, age at menarche and calcium intake were included in the multiple regression analyses with spinal and femoral BMD as dependent variables. Results: Overall, 38.6% had low spinal BMD and 7.9% had low femoral BMD. BMI (β=0.073, R2 = .148, P = .001, 95% CI [0.030, 0.116]) and current physical activity (β=0.071, R2 = .148, P = .017, 95% CI [0.013, 0.129]) were the only variables that were statistically significant in predicting spinal BMD. BMI (β=0.056, R2 = .13, P = .010, 95% CI [0.014, 0.098]) and current physical activ-ity (β=0.078, R2 = .13, P = .007, 95% CI [0.022, 0.134]) were also the only varia-bles that were statistically significant in predicting femoral BMD. Race was not a significant predictor of spinal or femoral BMD. Conclusion: It is imperative for both African-American and Caucasian women to engage in osteoporosis-preventive behaviors.

    Objective: The current study describes sleeping heart rate patterns in an adolescent cohort of Hispanic and Caucasian children over approximately a 5-year period to determine how sex, ethnicity, and body mass index (BMI) contribute to sleeping heart rate patterns over time. Methods: Participants were recruited from a large urban school district in the southwest United States as part of the Tucson Children's Assessment of Sleep Apnea Study (TuCASA). Heart rate data was obtained through electrocardiogram (ECG) recordings during in-home polysomnography, approximately 5 years apart. Second-wave cohort data were analyzed to determine how age, sex, ethnicity, physical activity, and BMI contribute to average sleeping heart rates. The same variables were used to investigate how sleeping heart rate patterns change longitudinally from school-age (6–11 years) to adolescence (10–17 years) during sleep. Results: Female adolescents had significantly faster average heart rates during sleep. Sleeping heart rate decreased significantly with increasing age in the adolescent cohort. Although the Hispanic group had a statistically significant higher body mass index than Caucasians, there were no significant differences in heart rate observed between ethnicities or in those who were classified as obese (BMI ≥ 95th percentile for age). Longitudinal analysis between the school-aged and adolescent cohort revealed a significant overall decrease in heart rate across a 5-year period. Conclusions: Hispanic and Caucasian adolescents experience a similar decrease in sleeping heart rate with age. Female adolescents had significantly faster heart rates than males, and no significant differences were observed between Caucasians and Hispanics, or obese vs. nonobese adolescents.

    Rotigotine is a dopamine receptor agonist indicated for the treatment of Parkinson's disease and moderate-to-severe restless legs syndrome. Continuous transdermal delivery of rotigotine via a silicon-based patch maintains stable plasma concentrations over 24 h. The objective of the study was to evaluate the pharmacokinetics, safety, and tolerability of a multiple-dose schedule of rotigotine transdermal patch in Japanese and Caucasian subjects. In this open-label, repeated-dose, parallel-group study (ClinicalTrials.gov: NCT01854216), healthy male and female subjects of Japanese or Caucasian ethnic origin were matched by gender, body mass index, and age. Subjects underwent a 9-day patch application period. 12 Japanese and 12 Caucasian subjects were included in the pharmacokinetic analyses. Mean apparent doses (actual amount of drug delivered) increased proportionally with rotigotine nominal dosages (1, 2, and 4 mg/24 h) and were similar for both ethnic groups, with large inter-individual variability. Mean plasma concentration-time profiles for unconjugated rotigotine were similar in both ethnic groups at day 3 for each dosage. Peak concentrations (C max,ss) and area under the concentration-time curves from pre-dose to the concentration measured 24 h after administration of patch (AUC(0-24,ss)) showed similar exposure in both groups; higher values in Japanese subjects were explained by differences in body weight. For total rotigotine, C max,ss and AUC(0-24,ss) values were higher in Caucasian subjects and could be explained by small differences in apparent dose. Rotigotine was generally well tolerated following multiple applications up to 4 mg/24 h. These findings suggest similar dosage requirements for rotigotine transdermal system in Japanese and Caucasian populations. PMID:25773763

    Epidermal inclusion cysts are a late complication of female genital circumcision, which is a practice that affects 125 million women primarily from Africa and the Middle East. A 30-year-old woman, gravida 4, para 1, presented to our clinic with an 8-year history of a slowly enlarging periclitoral mass. The patient had undergone female genital circumcision at the age of 5 years. We describe and video-illustrate the surgical technique of excising the 8-cm epidermal inclusion cyst. Using this technique, the entire cyst was resected intact, excess vulvar skin removed, and defect repaired. Postoperatively, she had minimal pain, no dyspareunia, and good cosmesis. Restoration of anatomy for this late complication of female genital circumcision is achievable with knowledge of anatomy, adherence to basic surgical principles that include tension-free closure, and close postoperative follow up.

    The purpose of this study was to examine high school students' math values, perceived math achievement, and STEM career choice. Participants (N=515) were rural high school students from the U.S. Northwest. Data was collected by administering the "To Do or Not to Do:" STEM pilot survey. Most participants (n=294) were Latinos, followed by Caucasians (n=142). Fifty-three percent of the students rated their math achievement as C or below. Of high math students, 57% were male. Females were 53% of low math students. Caucasians (61%) rated themselves as high in math in a greater proportion than Latinos (39%). Latinos (58%) rated themselves as low in math in a greater proportion than Caucasians (39%). Math Values play a significant role in students' perceived math achievement. Internal math values (r =.68, R2 =.46, p =.001) influenced perceived math achievement regardless of gender (males: r =.70, R2 =.49, p =.001; females: r =.65, R2 =.43, p =.001), for Latinos (r =.66, R2 =.44, p =.001), and Caucasians (r =.72, R2 =.51, p =.001). External math values (r =.53, R2 =.28, p =.001) influenced perceived math achievement regardless of gender (males: r =.54, R2 =.30, p =.001; females: r =.49, R2 =.24, p =.001), for Latinos (r =.47, R2 =.22, p =.001), and Caucasians (r =.58, R2 =.33, p =.001). Most high-math students indicated an awareness of being good at math at around 11 years old. Low-math students said that they realized that math was difficult for them at approximately 13 years of age. The influence of parents, teachers, and peers may vary at different academic stages. Approximately half of the participants said there was not a person who had significantly impacted their career choice; only a minority said their parents and teachers were influencing them to a STEM career. Parents and teachers are the most influential relationships in students' career choice. More exposure to STEM role models and in a variety of professions is needed.

    Herein, we present the case of a 22-year old obese Caucasian woman female with no acquired thrombophilic risk factors who was diagnosed with extensive cerebral sinus thrombosis. A detailed thrombophilia workup demonstrated persistently elevated plasminogen activator inhibitor 1 (PAI-1) activity levels, with an elevated PAI-1 antigen concentration and homozygosity for the PAI-1 4G allele (4G/4G genotype). The patient was treated with indefinite warfarin anticoagulation medication due to the unprovoked nature of her thrombotic event. Disturbances in the fibrinolytic system, in particular PAI-1, have been related to an increased risk of arterial and venous thrombosis. In this article, we discuss the pathophysiology of hypofibrinolysis associated with elevated PAI-1 levels and the PAI-1 4G/5G polymorphism. PMID:27287941

    Objective: Limited data are available on racial differences in clinical characteristics and burden in adult female acne. The objective was to describe racial differences in clinical characteristics, psychosocial impact, perceptions, behaviors, and treatment satisfaction in facial adult female acne. Design: Cross-sectional, web-based survey. Setting: Diverse sample of United States women. Participants: Women between the ages of 25 and 45 years with facial acne (≥25 visible lesions). Measurements: Outcomes included sociodemographic characteristics, psychosocial impacts, perceptions, behaviors, and treatment satisfaction. Racial differences were evaluated using descriptive statistics and t-test/chi-square analyses. Results: 208 females participated (mean age 35±6 years); 51.4 percent were White/Caucasian and 48.6 percent were non-White/Caucasian women [Black/African American (n=51); Hispanic/Latina (n=23); Asian (n=16); Other (n=ll)]. Age of acne onset (mean 14.8±5 vs. 17.0±8 years, p<0.05) and acne concern occurred earlier (16.6±7 vs. 19.3±9 years, p<0.05) in White/Caucasian than non-White/Caucasian subjects. Facial acne primarily presented on chin (28.0%) and cheeks (30.8%) for White/Caucasian women versus cheeks (58.4%) for non-White/Caucasian women. Non-White/Caucasian women experienced more postinflammatory hyperpigmentation than White/Caucasian women (p<0.0001). Facial acne negatively affected quality of life (QoL) in both groups, and most participants (>70%) reported some depression/anxiety symptoms. More White/Caucasian than non-White/Caucasian women were troubled by facial acne (88.8% vs. 76.2%, p<0.05). Lesion clearance was most important to White/Caucasian women (57.9 vs. non-White/Caucasian 31.7%, p<0.001); non-White/Caucasian females focused on postinflammatory hyperpigmentation clearance (41.6% vs. Caucasian 8.4%, p<0.0001). Conclusion: Results highlight racial differences in participant-reported clinical characteristics, attitudes, behaviors, and

    A large sample of adolescents brought for psychiatric evaluation to a public University based facility are the subjects of the study. Material incorporated in a DSM-III multiaxial formulation plus symptoms constituted the dependent variables. Analyses concentrated on ethnic differences, with variation associated with gender and social class controlled statistically. Caucasians showed comparatively greater clinical morbidity: higher number of Axis I definite diagnoses and level of symptoms. Eating disorder diagnoses were more common in Caucasians. There were no significant differences pertaining to level of stress or social impairment. Blacks showed higher levels of symptoms scored as "social aggression" and diagnosed as conduct disorders. The pattern of results raised the question of a possible referral bias, with blacks shunted to the psychiatric facility with lower levels of standard clinical psychopathology, but higher levels of social oppositional behavior. Further research is needed to verify if such a bias does exist. PMID:8444771

    Chronic lymphocytic leukemia (CLL) is a common hematological malignancy in Western countries. However, this disease is very rare in Asian countries. It is not clear whether the mechanisms of development of CLL in Caucasians and Asians are the same. We compared genetic abnormalities in Asian and Caucasian CLL using 250k GeneChip arrays. Both Asian and Caucasian CLL had four common genetic abnormalities: deletion of 13q14.3, trisomy 12, abnormalities of ATM (11q) and abnormalities of 17p. Interestingly, trisomy 12 and deletion of 13q14.3 were mutually exclusive in both groups. We also found that deletions of miR 34b/34c (11q), caspase 1/4/5 (11q), Rb1 (13q) and DLC1 (8p) are common in both ethnic groups. Asian CLL more frequently had gain of 3q and 18q. These suggest that classic genomic changes in the Asian and Caucasina CLL are same. Further, we found amplification of IRF4 and deletion of the SP140/SP100 genes; these genes have been reported as CLL-associated genes by previous genome-wide-association study. We have found classic genomic abnormalities in Asian CLL as well as novel genomic alteration in CLL. PMID:23708256

    Research on psychopathy among incarcerated, Caucasian males has consistently demonstrated deficits in emotion processing and response inhibition. Using the PCL-R to classify participants as psychopathic or non-psychopathic, this study examined the performance of incarcerated, Caucasian females on two laboratory tasks: A lexical decision task used to assess emotion processing and a passive avoidance task used to assess response inhibition. Contrary to prediction, deficits in performance typically exhibited by psychopathic males were not exhibited by psychopathic females in this sample. Implications of these findings are discussed and an interpretation of the results in the context of the Response Modulation Hypothesis is presented. PMID:21686054

    Summary This study was conducted to test whether there exists an association between vitamin D-binding protein (DBP) gene and compression strength index (CSI) phenotype. Candidate gene association analyses were conducted in total sample, male subgroup, and female subgroup, respectively. Two single-nucleotide polymorphisms (SNPs) with significant association results were found in males, suggesting the importance of DBP gene polymorphisms on the variation in CSI especially in Caucasian males. Introduction CSI of the femoral neck (FN) is a newly developed phenotype integrating information about bone size, body size, and bone mineral density. It is considered to have the potential to improve the performance of risk assessment for hip fractures because it is based on a combination of phenotypic traits influencing hip fractures rather than a single trait. CSI is under moderate genetic determination (with a heritability of ~44% found in this study), but the relevant genetic study is still rather scarce. Methods Based on the known physiological role of DBP in bone biology and the relatively high heritability of CSI, we tested 12 SNPs of the DBP gene for association with CSI variation in 405 Caucasian nuclear families comprising 1,873 subjects from the Midwestern US. Association analyses were performed in the total sample, male and female subgroups, respectively. Results Significant associations with CSI were found with two SNPs (rs222029, P=0.0019; rs222020, P=0.0042) for the male subgroup. Haplotype-based association tests corroborated the single-SNP results. Conclusions Our findings suggest that the DBP gene might be one of the genetic factors influencing CSI phenotype in Caucasians, especially in males. PMID:19543766

    South Asian adults are known to have very high rates of Coronary heart disease (CHD) and insulin resistance and, even as adolescents, may show higher risk factors for CHD. The aim of this study was to investigate the prevalence of small, dense low density lipoprotein (sdLDL) subclasses in a cohort of adolescent boys. The specific objective was to investigate the relationship between measures of fatness, ethnicity and LDL diameter in this cohort. Preformed native (non-denaturing) polyacrylamide 3-13% gradient gels and a multipurpose vertical electrophoresis system were used for the separation of LDL sub-fractions in a single school year cohort of boys aged 15-16 years (n=135). Latex beads and thyroglobulin standards were used to construct a calibration curve in order to calculate LDL particle diameters by regression (Total Lab Software v1.11). ANOVA was used to compare LDL size among different ethnic groups (SPSS and Stat View). The study sample was comprised of 45.2% Caucasians, 41.5% East Asians and 13.3% from the Indian subcontinent (South Asians). There was a non-significant trend for South Asians to have a lower LDL diameter than either Caucasians or East Asian boys which was independent of % total body fat (%TBF) and body mass index (BMI). This is the first adolescent cohort to examine sdLDL which included Caucasians, East and South Asians. It appears that the higher risk profile for CHD and diabetes noted in South Asian adults may be evident even during adolescence. PMID:17077065

    This study aimed to derive quantitative abundance values for key hepatic transporters suitable for in vitro-in vivo extrapolation within a physiologically based pharmacokinetic modeling framework. A meta-analysis was performed whereby data on abundance measurements, sample preparation methods, and donor demography were collated from the literature. To define values for a healthy Caucasian population, a subdatabase was created whereby exclusion criteria were applied to remove samples from non-Caucasian individuals, those with underlying disease, or those with subcellular fractions other than crude membrane. Where a clinically relevant active genotype was known, only samples from individuals with an extensive transporter phenotype were included. Authors were contacted directly when additional information was required. After removing duplicated samples, the weighted mean, geometric mean, standard deviation, coefficient of variation, and between-study homogeneity of transporter abundances were determined. From the complete database containing 24 transporters, suitable abundance data were available for 11 hepatic transporters from nine studies after exclusion criteria were applied. Organic anion transporting polypeptides OATP1B1 and OATP1B3 showed the highest population abundance in healthy adult Caucasians. For several transporters, the variability in abundance was reduced significantly once the exclusion criteria were applied. The highest variability was observed for OATP1B3 > OATP1B1 > multidrug resistance protein 2 > multidrug resistance gene 1. No relationship was found between transporter expression and donor age. To our knowledge, this study provides the first in-depth analysis of current quantitative abundance data for a wide range of hepatic transporters, with the aim of using these data for in vitro-in vivo extrapolation, and highlights the significance of investigating the background of tissue(s) used in quantitative transporter proteomic studies.

    INTRODUCTION Class II malocclusion affects about 15 % of the US population and is characterized by a convex profile and occlusion disharmonies. The specific etiological mechanisms resulting in the range of Class II dento-skeletal combinations observed is not yet understood. Most studies describing the class II phenotypic diversity have utilized moderate sample sizes or have focused on younger individuals that later in life may outgrow their class II discrepancies; such a focus may also preclude the visualization of adult class II features. The majority have utilized simple correlation methods resulting in phenotypes that may not be generalizable to different samples and thus may not be suitable for studies of malocclusion etiology. The purpose of this study is to address these knowledge gaps by capturing the maximum phenotypic variation present in a large Caucasian sample of class II individuals selected with strict eligibility criteria and rigorously standardized multivariate reduction analyses. METHODS Sixty-three lateral cephalometric variables were measured from pre-treatment records of 309 Class II Caucasian adults (82 males, 227 females; ages 16–60 years). Principal component analysis (PCA) and cluster analysis were used to generate comprehensive phenotypes in an effort to identify the most homogeneous groups of individuals reducing heterogeneity and improving the power of future malocclusion etiology studies. RESULTS PCA resulted in 7 principal components that accounted for 81% of the variation. The first three components represented variation on mandibular rotation, upper incisor angulation and mandibular length, respectively. The cluster analysis identified 5 distinct Class II phenotypes. CONCLUSIONS A comprehensive spectrum of Class II phenotypic definitions was obtained that could be generalized to other samples advancing our efforts to the identification of etiological factors underlying Class II malocclusion.

    Menopause is one of the crucial physiological events during the life of a woman. Transition of menopause status is accompanied by increased risks of various health problems such as osteoporosis. Peripheral blood monocytes can differentiate into osteoclasts and produce cytokines important for osteoclast activity. With quantitative proteomics LC-nano-ESI-MS(E) (where MS(E) is elevated-energy MS), we performed protein expression profiling of peripheral blood monocytes in 42 postmenopausal women with discordant bone mineral density (BMD) levels. Traditional comparative analysis showed proteins encoded by four genes (LOC654188, PPIA, TAGLN2, YWHAB) and three genes (LMNB1, ANXA2P2, ANXA2) were significantly down- and upregulated, respectively, in extremely low- versus high-BMD subjects. To study functionally orchestrating groups of detected proteins in the form of networks, we performed weighted gene coexpression network analysis and gene set enrichment analysis. Weighted gene coexpression network analysis showed that the module including the annexin gene family was most significantly correlated with low BMD, and the lipid-binding related GO terms were enriched in this identified module. Gene set enrichment analysis revealed that two significantly enriched gene sets may be involved in postmenopausal BMD variation by regulating pro-inflammatory cytokines activities. To gain more insights into the proteomics data generated, we performed integrative analyses of the datasets available to us at the genome (DNA level), transcriptome (RNA level), and proteome levels jointly.

    Compression from median arcuate ligament was observed during multidetector 64-row computed tomography in a Caucasian 30-year-old female. The patient was referred for examination to exclude anatomical pathologies causing hypertension. The examination demonstrated that left renal artery, which had its origin in the chest (at the level of upper one-third of Th12), was compressed as it passed by median arcuate ligament of the diaphragm. In addition, aortic compression and kinked shape was also revealed. PMID:25940812

    Secondary hypokalemic periodic paralysis is rare. However, when it occurs, it is usually associated with Graves' disease and it is mostly diagnosed in Asiatic male patients. In this report, we analyze the diagnostic procedure in three cases of hypokalemic periodic paralysis associated with Graves' disease, diagnosed in three different emergency care units over the last 3 years. Three Caucasian men (26, 30, and 39 years of age) came to the emergency care unit for acute tetraparesia. One of them had suffered 15 stereotypical episodes of tetraparesia during the last 2 years. Goiter was present in each case. Kalemia was 1.8, 2.1, and 3 mmol/l, respectively. Triggering events such as considerable sugar intake and physical exercise were present in two cases. In all cases, low TSH levels, high FT4 levels, and anti-TSH receptor antibodies led to the diagnosis of Graves' disease. All patients were treated with potassium supplementation and neomercazole. Outcome was good with a follow-up of 6, 9, and 24 months, respectively. Emergency care practitioners should be aware of this diagnosis, which may affect Caucasian patients presenting with transient tetraparesia in a primary care unit. PMID:16137557

    Anabolic androgenic steroids (AAS) are synthetic testosterone derivatives which undergo extensive metabolism in man. Differences in the excretion of phase II metabolites are strongly associated with inter-individual and inter-ethnic variations. Sulfate metabolites have been described as long-term metabolites for some AAS. Clostebol is the 4-chloro derivative of testosterone and the aim of the present study was the evaluation of clostebol sulfate metabolites in Caucasian population by LC-MS/MS technology. Clostebol was orally administered to four healthy Caucasian male volunteers, and excretion study urines were collected up to 31 days. Several analytical strategies (neutral loss scan, precursor ion scan and selected reaction monitoring acquisitions modes) were applied to detect sulfate metabolites in post-administration samples. Sixteen sulfate metabolites were detected, five of them having detectability times above 10 days (S1a, S2a, S3b, S3g and S4b). Interestingly, metabolite S1a could be detected up to the last collected sample of all excretion studies and it was characterized by LC-MS/MS and GC-MS as 4ξ-chloro-5α-androst-3β-ol-17-one 3β-sulfate. Thus, monitoring of S1a improves the detection time of clostebol misuse with respect to the commonly monitored metabolites, excreted in the glucuronide fraction. Importantly, this new metabolite can be incorporated into recently developed LC-MS/MS screening methods base on the direct detection of phase II metabolites. PMID:27085012

    Acute aerobic exercise produces post-exercise hypotension (PEH). Chinese populations have lower prevalence of cardiovascular disease compared to Caucasians. PEH may be associated cardiovascular disease through its influence on hypertension. The purpose of this study was to compare PEH between Caucasian and Chinese subjects following acute aerobic exercise. 62 (30 Caucasian and 32 Chinese, 50% male) subjects underwent measurement of peripheral and central hemodynamics as well as arterial and cardiac evaluations, 30 min and 60 min after 45 min of treadmill exercise. Caucasians exhibited significantly higher baseline BP than the Chinese. While the reduction in brachial artery systolic BP was greater in Caucasian than in the Chinese, there was no difference in changes in carotid systolic BP between the groups. The increase in cardiac output and heart rate was greater in the Chinese than Caucasians, but total peripheral resistance and leg pulse wave velocity decreased by a similar magnitude in the Chinese and Caucasian subjects. We conclude that acute aerobic exercise produces a greater magnitude of PEH in peripheral systolic BP in Caucasian compared to Chinese subjects. The different magnitude in PEH was caused by the greater increase in cardiac output mediated by heart rate, with no change in stroke volume. It is possible that initial BP differences between races influenced the findings. PMID:25329430

    INTRODUCTION Class III malocclusion is characterized by a composite of dento-skeletal patterns that lead to the forward positioning of the mandibular teeth in relation to the maxillary teeth and a concave profile. Environmental and genetic factors are associated with this condition, which affects 1% of the US population and imposes significant esthetic and functional burdens on affected individuals. The purpose of this study was to capture the phenotypic variation present in a large sample of white adults with Class III malocclusion by using multivariate reduction methods. METHODS Sixty-three lateral cephalometric variables were measured from pre-treatment records of 292 Class II Caucasian adults (126 males, 166 females; ages 16-57 years). Principal component analysis and cluster analysis were used to capture the phenotypic variation and identify the most homogeneous groups of individuals to reduce genetic heterogeneity. RESULTS Principal component analysis resulted in 6 principal components that accounted for 81.2% of the variation. The first three components represented variations in mandibular horizontal and vertical position, maxillary horizontal position, and mandibular incisor angulation, respectively. The cluster model identified 5 distinct subphenotypes of Class III malocclusion. CONCLUSIONS A spectrum of phenotypic definitions was obtained replicating results of previous studies and supporting the validity of these phenotypic measures in future research of genetic and environmental etiology of Class III malocclusion.

    The all-female Caucasian rock lizard species Darevskia dahli and other parthenogenetic species of this genus reproduce normally via true parthenogenesis. Previously, the genetic diversity of this species was analyzed using allozymes, mitochondrial DNA, and DNA fingerprint markers. In the present study, variation at three microsatellite loci was studied in 111 specimens of D. dahli from five populations from Armenia, and new information regarding clonal diversity and clone formation in D. dahli was obtained that suggests a multiple hybridization origin. All individuals but one were heterozygous at the loci studied. Based on specific allele combinations, 11 genotypes were identified among the individuals studied. Individuals with the same genotypes formed distinct clonal lineages: one major clone was represented by 72 individuals, an intermediate clone was represented by 21 individuals, and nine other clones were rare and represented by one or several individuals. A new approach based on the detection and comparison of genotype-specific markers formed by combinations of parental-specific markers was developed and used to identify at least three hybridization founder events that resulted in the initial formation of one major and two rare clones. All other clones, including the intermediate and seven rare clones, probably arose through postformation microsatellite mutations of the major clone. This approach can be used to identify hybridization founder events and to study clone formation in other unisexual taxa. PMID:24896777

    The all-female Caucasian rock lizard species Darevskia dahli and other parthenogenetic species of this genus reproduce normally via true parthenogenesis. Previously, the genetic diversity of this species was analyzed using allozymes, mitochondrial DNA, and DNA fingerprint markers. In the present study, variation at three microsatellite loci was studied in 111 specimens of D. dahli from five populations from Armenia, and new information regarding clonal diversity and clone formation in D. dahli was obtained that suggests a multiple hybridization origin.

    Autoerythrocyte sensitization syndrome is a psychologically induced painful bruising condition. Two female, 19 and 30-year-old presented with recurrent episodes of painful ecchymotic bruising over accessible areas of body. In the younger female, episodes were since 3 years and were precipitated by stress and trivial trauma. The elder female presented with similar lesions since 3 months which were spontaneous in presentation. There were no obvious psychiatric manifestations in either. Clinically, ecchymotic changes in various stages of development were seen. Routine hemogram and coagulation profile were normal. Histopathology showed extravasated erythrocytes, perivascular neutrophils and fibrinoid deposition. Intradermal injection of autologous whole blood produced a painful ecchymotic reaction after 2 h similar to the presenting lesions. Psychiatric evaluation revealed mild mixed depression - anxiety disorder in the younger female while the latter revealed no abnormalities. The diagnosis of autoerythrocyte sensitization syndrome was made based on clinical history and findings, positive autoerythrocyte sensitization test, psychiatric evaluation and absence of any other clinical or laboratory pathology.

    During platinum group metals (PGMs) refining the possibility exists for dermal exposure to PGM salts. The dermal route has been questioned as an alternative route of exposure that could contribute to employee sensitisation, even though literature has been focused on respiratory exposure. This study aimed to investigate the in vitro permeation of platinum and rhodium through intact Caucasian skin. A donor solution of 0.3mg/ml of metal, K2PtCl4 and RhCl3 respectively, was applied to the vertical Franz diffusion cells with full thickness abdominal skin. The receptor solution was removed at various intervals during the 24h experiment, and analysed with high resolution ICP-MS. Skin was digested and analysed by ICP-OES. Results indicated cumulative permeation with prolonged exposure, with a significantly higher mass of platinum permeating after 24h when compared to rhodium. The mass of platinum retained inside the skin and the flux of platinum across the skin was significantly higher than that of rhodium. Permeated and skin retained platinum and rhodium may therefore contribute to sensitisation and indicates a health risk associated with dermal exposure in the workplace. PMID:25084315

    Young infants are known to prefer own-race faces to other race faces and recognize own-race faces better than other-race faces. However, it is entirely unclear as to whether infants also attend to different parts of own- and other-race faces differently, which may provide an important clue as to how and why the own-race face recognition advantage emerges so early. The present study used eye tracking methodology to investigate whether 6- to 10-month-old Caucasian infants (N = 37) have differential scanning patterns for dynamically displayed own- and other-race faces. We found that even though infants spent a similar amount of time looking at own- and other-race faces, with increased age, infants increasingly looked longer at the eyes of own-race faces and less at the mouths of own-race faces. These findings suggest experience-based tuning of the infant's face processing system to optimally process own-race faces that are different in physiognomy from other-race faces. In addition, the present results, taken together with recent own- and other-race eye tracking findings with infants and adults, provide strong support for an enculturation hypothesis that East Asians and Westerners may be socialized to scan faces differently due to each culture's conventions regarding mutual gaze during interpersonal communication.

    Rapid urbanisation has led African women to have an obesity prevalence double than that of Caucasian women, and this also holds true for the stroke prevalence in Africans. The study aimed to compare various metabolic syndrome (MS) criteria of the International Diabetes Federation (IDF) of body mass index and age-matched African (n=102) and Caucasian women (n=115). More Caucasian (30.4%) than African women (24.8%) had MS. Only 48% of African women had waist circumferences (WC) higher than the IDF cutoff, compared to 62.6% of Caucasians. Caucasian women were significantly taller and heavier and had higher triglycerides, plasminogen activator inhibitor-1 activity, and cortisol. African women had significantly higher blood pressure, leptin, fibrinogen and C-reactive protein, and higher odds ratios for having the MS for HDL-cholesterol, blood pressure, and fasting glucose than Caucasians. It is concluded that the IDF WC criterion needs a downward adjustment for African women due to a smaller body size. Lean African women seem to be at higher risk for MS than Caucasians. South Africa needs to stem the increasing rates of type 2 diabetes by decreasing obesity and by education (unschooled African women showed a 4.8 times higher likelihood of having MS than schooled women).

    Aims The aim of this study was to investigate the heritability as well as genetic and environmental correlations of left ventricular (LV) structural and functional traits in complex pedigrees of a Caucasian population. Methods and results We randomly recruited 459 white European subjects from 52 families (50% women; mean age 45 years). LV structure was measured by M-mode and 2D echocardiography and LV function was measured by conventional Doppler and tissue Doppler imaging (TDI). Other measurements included blood pressure, anthropometric, and biochemical measurements. We estimated the heritability of LV traits while adjusting for covariables, including sex, age, body height and weight, systolic and diastolic blood pressures, and heart rate. With full adjustment, heritability of LV mass was 0.23 (P= 0.025). The TDI-derived mitral annular velocities Ea and Aa showed moderate heritability (h2= 0.36 and 0.53, respectively), whereas the mitral inflow A peak had weak heritability (h2 = 0.25) and the E peak was not heritable (h2 = 0.11). We partitioned the total phenotypic correlation when it reached significance, into a genetic and an environmental component. The genetic correlations were 0.61 between the E and Ea peaks and 0.90 between the A and Aa peaks. Conclusion Our study demonstrated moderate heritability for LV mass as well as the mitral annular Ea and Aa peaks. We also found significant genetic correlations between the E and Ea peaks and between the A and Aa peaks. Our current findings support the ongoing research to map and detect genetic variants that contribute to the variation in LV mass and other LV structural and functional phenotypes. PMID:21398654

    Examined relationships among negative life events, four locus of control attributions (Internality, Powerful Others, Chance and God Control), and psychological distress for Korean American versus Caucasian American Protestants. Negative events and Powerful Others beliefs were positively related to distress, whereas Internality was negatively related to distress. Ethnicity and God Control interacted: The relationship between God Control beliefs and anxiety was negative for Caucasians but positive for Koreans. Three-way interactions (Ethnicity x Locus of Control x Negative Events) also emerged. As Caucasians' Powerful Others beliefs increased, the positive relationship between negative events and depression became stronger; Koreans' Powerful Others beliefs had no such effect. As Caucasians' God Control beliefs increased, the negative event-depression relationship changed from positive to negative; the reverse was true for Koreans. Findings support the value of assessing ethnoculture and religiousness in stressful life events research. PMID:9231996

    Coping strategies have significant effects on older people's health. This study examined whether gender and ethnic differences influence the coping strategies chosen by older adults when they encounter daily life stressors. Data were collected from 444 community-dwelling people over the age of 65, including 238 Caucasian Americans and 206 Korean Americans. Results showed significant differences between the two groups. Korean Americans had higher scores on problem and emotion-focused coping strategies as well as avoidant coping strategies than Caucasian Americans. Caucasian older women employed more active coping, planning, and positive reframing skills; relied more on religion; and sought emotional support more than Caucasian men. For Korean Americans, older women utilized religion and denial; whereas older men employed instrumental support and substance abuse. The results suggest that practitioners should develop ethnic, gender-specific programs to help older adults cope more effectively with their daily life stressors. PMID:25260229

    In racial disparities research, perceived discrimination is a proposed risk factor for unfavorable health outcomes. In a proposed “threshold-constraint” theory, discrimination intensity may exceed a threshold and require coping strategies, but social constraint limits coping options for African Americans, who may react to perceived racial discrimination with disengagement, because active strategies are not viable under this social constraint. Caucasian Americans may experience less discrimination and lower social constraint, and thus may use more active coping strategies. 213 African Americans and 121 Caucasian Americans with cancer participated by completing measures of mistreatment, coping, and quality of life. African Americans reported more mistreatment than Caucasian Americans (p< 001) and attributed mistreatment more to race/ethnicity (p < .001). In the mistreatment-quality of life relationship, disengagement was a significant mediator for Caucasians (B = −.39;CI .13–.83) and African Americans (B = −.20;CI .07–.43). Agentic coping was a significant mediator only for Caucasians (B = −.48;CI .18–.81). Discrimination may exceed threshold more often for African Americans than for Caucasians and social constraint may exert greater limits for African Americans. Results suggest that perceived discrimination affects quality of life for African Americans with cancer because their coping options to counter mistreatment, which is racially based, are limited. This process may also affect treatment, recovery, and survivorship. PMID:25090144

    It is uncertain when female circumcision was first practiced, but it certainly preceded the founding of both Christianity and Islam. A review of past and current historical, popular and professional literature was undertaken, and 4 types of female circumcision were identified. Typically female circumcision is performed by a local village practitioner, lay person or by untrained midwives. Female genital mutilation is not accepted by any religious or medical opinion, and is a violation of human rights against helpless individuals who are unable to provide informed consent and who must therefore be protected through education and legislation. Complications of female circumcision can present after many years. Any medical practitioner (either for adult or pediatric) can be confronted with this issue of female circumcision, even in countries where this custom is not present, thus mandating the understanding of this complex issue.

    Activation of the hypothalamic-pituitary-adrenal axis leads to secretion of cortisol, which binds to peripheral glucocorticoid receptor and mediates a complex series of metabolic and immune effects. Cortisol also binds to receptors in the hypothalamus and pituitary, and inhibits further secretion of adrenocorticotropic hormone thus preventing an excessive response. Excess glucocorticoid effect is seen in Cushings disease, adrenal adenomas/carcinomas and in glucocorticoid resistance. Within such pathology there are health consequences of excessive glucocorticoid action, including obesity, hypertension, and glucose intolerance or diabetes. We hypothesized that increased glucocorticoid receptor in peripheral tissue might mediate an excess glucocorticoid effect in the absence of increased cortisol secretion. The objective of the study was to investigate the relationship between glucocorticoid receptor density in leukocytes and health risk indices relevant to obesity and diabetes in a sample of Caucasian and African American subjects. Comparison of glucocorticoid receptor concentration with subject body mass index, percentage body fat, waist circumference, insulin resistance, plasma cortisol levels, gender, and lipid profiles were conducted. Increased glucocorticoid receptor density significantly correlated with body mass index, percentage body fat, waist circumference, and insulin resistance. No significant correlation was observed for glucocorticoid receptor density with lipid profiles. Furthermore, no significant differences were observed in glucocorticoid receptor density between Caucasian and African American subjects or male and female participants. Our results show that high risk health conditions, such as obesity and type-2 diabetes, may be associated with a form of hypothalamic-pituitary-adrenal axis dysfunction, characterized by localized leukocyte glucocorticoid receptor over-expression.

    Several previous studies found that Asians transplanted for hepatitis B virus (HBV) infection had worse post-transplant outcomes than Caucasians. Data on post-transplant outcomes of African Americans and waitlist outcomes of Asian Americans and African Americans with hepatitis B are scant. The aim of this study was to compare waitlist and post-transplant outcomes among Asian Americans, African Americans, and Caucasians who had HBV-related liver disease. Data from a retrospective-prospective study on liver transplantation for HBV infection were analyzed. A total of 274 patients (116 Caucasians, 135 Asians, and 23 African Americans) from 15 centers in the United States were enrolled. African Americans were younger and more Asian Americans had hepatocellular carcinoma (HCC) at the time of liver transplant listing. The probability of undergoing transplantation and the probability of survival on the waitlist were comparable in the 3 racial groups. Of the 170 patients transplanted, 19 died during a median follow-up of 31 months. The probability of post-transplant survival at 5 years was 94% for African Americans, 85% for Asian Americans, and 89% for Caucasians (P = 0.93). HCC recurrence was the only predictor of post-transplant survival, and recurrence rates were similar in the 3 racial groups. Caucasians had a higher rate of HBV recurrence: 4-year recurrence was 19% versus 7% and 6% for Asian Americans and African Americans, respectively (P = 0.043). In conclusion, we found similar waitlist and post-transplant outcomes among Caucasians, Asian Americans, and African Americans with hepatitis B. Our finding of a higher rate of HBV recurrence among Caucasians needs to be validated in other studies. PMID:19718627

    We compared arterial elasticity in American Indian and Caucasian children, adolescents, and young adults, and we assessed whether demographic, body composition, and ambulatory activity measures were predictive of arterial elasticity within each group. Fifty-one American Indians and 66 Caucasians between the ages of 8 and 30 years were assessed on large artery elasticity index, small artery elasticity index, body fat percentage, and daily ambulatory activity during 7 consecutive days. American Indians had a higher percentage of body fat than Caucasians (p = 0.002), whereas daily ambulatory activity measures were similar (p > 0.05). American Indians had a 16% lower large artery elasticity index (p = 0.007) and a 19% lower small artery elasticity index (p < 0.001) than Caucasians. The regression model for large artery elasticity index included average cadence (p = 0.001), fat-free mass (p < 0.001), age component (Caucasian only) (p < 0.001), and sex (p = 0.025). The regression model for small artery elasticity index included fat-free mass (p < 0.001), maximum cadence for 30 continuous minutes (p = 0.009), race (p = 0.005), and average cadence (p = 0.049). Between 8 and 30 years of age, elasticity means for the large and small arteries is lower in American Indians than in Caucasians. A smaller difference was observed in children, with a trend to a much larger difference in young adults. Furthermore, greater fat-free mass and higher daily ambulatory cadence are associated with higher arterial elasticity in both American Indians and Caucasians. PMID:21828174

    Super Koropon primer (MB0125-055) plays a significant role in the corrosion protection of areas throughout the Orbiter. Because the Shuttle Program relies so heavily upon the performance of the Koropon primer, it is necessary to fully understand all aspects of the behavior of the coating. One area where little understanding of the Koropon primer still exists is the level of risk associated with age related degradation. Recently, efforts were undertaken to better understand the age life of the Koropon primer and to gain some insight into the aging process of this coating. In that study, an aluminum access panel from the Orbiter Enterprise was used to investigate the performance of the old Koropon film. A control panel was also used to study the performance of new Koropon coating. Preliminary investigations into the performance of aged Super Koropon primer indicated a significant decrease in corrosion protection. This investigation serves as an example of how Focused Ion Beam/Scanning Microscopy can be used to characterize the changes that occur as coatings age.

    BACKGROUND: First Nation populations in Canada have a very low incidence of inflammatory bowel disease (IBD). Based on typical infections in this population, it is plausible that the First Nations react differently to microbial antigens with a different antibody response pattern, which may shed some light as to why they experience a low rate of IBD. OBJECTIVE: To compare the positivity rates of antibodies known to be associated with IBD in Canadian First Nations compared with a Canadian Caucasian population. METHODS: Subjects with Crohn’s disease, ulcerative colitis (UC), rheumatoid arthritis (RA) (as an immune disease control) and healthy controls without a personal or family history of chronic immune diseases, were enrolled in a cohort study aimed to determine differences between First Nations and Caucasians with IBD or RA. Serum from a random sample of these subjects (n=50 for each of First Nations with RA, First Nations controls, Caucasians with RA, Caucasians with Crohn’s disease, Caucasians with UC and Caucasians controls, and as many First Nations with either Crohn’s disease or UC as could be enrolled) was analyzed in the laboratory for the following antibodies: perinuclear antineutrophil cytoplasmic antibody (pANCA), and four Crohn’s disease-associated antibodies including anti-Saccharomyces cerevisiae, the outer membrane porin C of Escherichia coli, I2 – a fragment of bacterial DNA associated with Pseudomonas fluorescens, and the bacterial flagellin CBir-1. The rates of positive antibody responses and mean titres among positive results were compared. RESULTS: For pANCA, First Nations had a positivity rate of 55% in those with UC, 32% in healthy controls and 48% in those with RA. The pANCA positivity rate was 32% among Caucasians with RA. The rates of the Crohn’s disease-associated antibodies for the First Nations and Caucasians were comparable. Among First Nations, up to one in four healthy controls were positive for any one of the Crohn

    Age-specific hip fracture incidence has been increasing in some parts of the world. The incidence of hip fractures among Japanese on the island of Oahu, Hawaii in 1979-1981 was approximately half that of Caucasians in North America, but similar to the incidence in Japan. We surveyed the incidence on Oahu again in 1991-1995 for all races to compare the incidence among Japanese to the earlier rates, and to other populations, including Caucasians on Oahu. The incidence of hip fracture among Japanese in Hawaii between 1991-1995 had not changed appreciably (compared to 1979-1981), and was similar to that among Caucasians on Oahu. The incidence among Hawaii Japanese and Caucasians was similar to, or lower than Japan overall, and much lower (one-third to one-half) than that reported for Caucasians in North America and Northern Europe, suggesting that the prevalence of certain risk factors may be lower in Hawaii. These findings confirm other studies suggesting that nongenetic factors may be responsible for much of the observed differences in hip fracture incidence between countries, and between races.

    Recent genome-wide association studies (GWASs) conducted in Asian populations have identified novel risk loci for systemic lupus erythematosus (SLE). Here, we genotyped 10 single-nucleotide polymorphisms (SNPs) in eight such loci and investigated their disease associations in three independent Caucasian SLE case–control cohorts recruited from Sweden, Finland and the United States. The disease associations of the SNPs in ETS1, IKZF1, LRRC18-WDFY4, RASGRP3, SLC15A4, TNIP1 and 16p11.2 were replicated, whereas no solid evidence of association was observed for the 7q11.23 locus in the Caucasian cohorts. SLC15A4 was significantly associated with renal involvement in SLE. The association of TNIP1 was more pronounced in SLE patients with renal and immunological disorder, which is corroborated by two previous studies in Asian cohorts. The effects of all the associated SNPs, either conferring risk for or being protective against SLE, were in the same direction in Caucasians and Asians. The magnitudes of the allelic effects for most of the SNPs were also comparable across different ethnic groups. On the contrary, remarkable differences in allele frequencies between Caucasian and Asian populations were observed for all associated SNPs. In conclusion, most of the novel SLE risk loci identified by GWASs in Asian populations were also associated with SLE in Caucasian populations. We observed both similarities and differences with respect to the effect sizes and risk allele frequencies across ethnicities. PMID:23249952

    Within the last four decades Asia has witnessed major transformation in its population demographics, which gave rise to changes in food availability, food habits and lifestyle. A significant consequence of these changes has been the continuing rise in overweight and obesity across Asia. In parallel, there has been a significant rise in Asians in the incidence of the major chronic diseases, particularly in cardiometabolic disorders such as metabolic syndrome, type 2 diabetes, hypertension, and other cardiovascular diseases. Given that the majority of the evidence, to date, investigating the associations between adiposity and cardiometabolic disorder risk have been obtained from studies undertaken either in European or in North American Caucasians, in this chapter, we have reviewed differences in body fat content and distribution between East Asians, South Asians, and Caucasians. The evidence is consistent that the content and distribution of body fat are markedly different between the various ethnic groups. We found that Asians have a greater predisposition towards adiposity at higher BMI than in Caucasians. Moreover, at any given level of adiposity, Asians have a much greater predisposition to risk of cardiometabolic disorders than Caucasians. We therefore strongly endorse the need for different adiposity cutoffs in Asians as compared to the Caucasians. We have also reviewed the predictive abilities of the various body composition/adiposity measures in determining risk of cardiometabolic disorders in Asians. PMID:26319906

    Few studies have assessed relationships between perceived racism, racism-related stress, and alcohol problems. The current study examined these relationships within the context of tension reduction models of alcohol consumption. Participants were 94 African American and 189 Caucasian college freshmen who completed an online survey assessing perceived racism, alcohol consequences, alcohol consumption, negative affect, and deviant behavior. Hierarchical multiple regressions indicated that racism-related stress predicted alcohol consequences for both African American and Caucasian college students, even after controlling for alcohol consumption, negative affect, and behavioral deviance. The frequency of racist events predicted alcohol consequences for Caucasian but not African American students. These findings highlight the need to address racism and racism-related stress in college-based alcohol prevention and intervention efforts. PMID:23046273

    The purpose of this study is to investigate differences in attitudes toward rape between Asian and Caucasian college students. The Attitudes Toward Rape scale was used to measure beliefs about rape in a convenience sample of 169 college students. Three items regarding stranger rape myths were added. Findings suggest that Asian students are more likely than Caucasian students to believe women should be held responsible for preventing rape and to view sex as the primary motivation for rape. Asians also have stronger beliefs than Caucasians do that victims cause the rape and that most rapists are strangers. This research suggests that outreach programs can play an important role in providing information, education, and prevention regarding rape and that males and Asian students should be target populations for such programs.

    Introduction The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descents with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample. Methods Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40), Japanese-Brazilian (n = 32) and Mongoloid (n = 33). The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr. Results Statistical differences (P < 0.05) indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group. Conclusion The dental patterns found for the Japanese-Brazilian descents were, in general, more similar to those of the Mongoloid sample. PMID:25279521

    African American participation in Alzheimer's disease (AD) research studies has been historically low. To determine whether older African Americans and Caucasians had different knowledge or attitudes related to AD, we administered the Alzheimer's Disease Knowledge Scale (ADKS) to 67 older African Americans and 140 older caucasians in the greater Atlanta area as well as questions targeting locus of control over general health and AD risks. Older African Americans scored slightly lower on ADKS than older caucasians, with race only accounting for 1.57 (95% confidence interval [CI] 0.57-2.61, P < .001) points of difference in a multivariate model. Attitudes toward AD were also similar between the 2 groups but 1 (35.7%) in 3 adults reported control over general health but not AD risks. In addition to enhancing education content in outreach efforts, there is an urgent need to address the perception that future AD risks are beyond one's own internal control. PMID:26646115

    Catechol-O-methyl transferase (COMT) is an important estrogen-metabolizing enzyme, and common genetic variants in this gene could affect breast cancer risk. We conducted a large population-based case control study in Massachusetts, New Hampshire, and Wisconsin to examine six strategically selected COMT haplotype-tagging (ht) single nucleotide polymorphism (SNPs), including the val158met polymorphism (rs4680), in relation to breast cancer risk. Analyses were based on 1,655 Caucasian women with invasive breast cancer and 1,470 Caucasian controls. None of the six individual SNPs were associated with breast cancer risk. The global test for haplotype associations was nonsignificant (p- value=0.097), although two uncommon haplotypes present in 6% of the study population showed statistically significant inverse associations with risk. These results suggest that genetic variation in COMT has no significant association with breast cancer risk among Caucasian women. PMID:20150638

    Largescale genome-wide association studies (GWAS) showed that the TOMM40 rs2075650 polymorphism is significantly associated with Alzheimer's disease (AD) in Caucasian ancestry and Asian population. Here, we evaluated this association with large-scale samples from selected 12 studies (N=28,515; 10,358 cases and 18,157 controls) through the PubMed, AlzGene, and Google Scholar. We identified a significant association between rs2075650 and AD with P=0.000, OR=4.178 and 95% CI 1.891-9.228. In subgroup analysis, we identified significant association between rs2075650 polymorphism and AD in both Asian and Caucasians but not mixed populations. Collectively, our analysis shows TOMM40 rs2075650 polymorphism is associated with AD susceptibility in Asian, Caucasian, and mixed populations. We believe that our analysis will be helpful for future genetic researches on AD. PMID:27328316

  14. Average heterozgosity of STRPs in the Pima Indians is lower than in Caucasians

    The Pima Indians of Arizona have the highest reported prevalence of non-insulin dependent diabetes (NIDDM) in the world. To localize regions of the genome which may contain genes important in the predisposition to NIDDM, we are producing a high density genetic map in this population. In contrast to previous studies in the Pima which have examined polymorphisms in single genes or small genetic regions, we are using short tandem repeated polymorphisms (STRPs) as genetic markers covering the entire genome. We have genotyped over 150 STRPs in a sample consisting of approximately 1000 individuals comprising 250 nuclear families. Many of these STRPs were originally typed in a sample of Caucasians (CEPH) thus allowing direct comparisons between populations. Our analyses indicate that the average heterozygosity of the STRPs is 11% lower in the Pima (P<0.001). A survey of 8 different blood group markers in the Pima showed a 17% difference in average heterozygosity when compared with North American Caucasians (P<0.001). In contrast, a sample of 11 restriction fragment length polymorphisms (RFLPs) does not show a similar difference in average heterozygosity. The average heterozygosity is 3% higher in the Pima as compared to Caucasians for these 11 RFLPs (P<0.001). There is a significant correlation between estimates of heterozygosity based on the sample of STRP markers in Pima and Caucasians (R=0.48 P<0.001), but less than 25% of the variance is explained by this relationship, presumably reflecting different evolutionary histories for each group since divergence of these two populations. In addition to differences in allele frequencies between the two populations, we have tentatively identified a number of markers which differ from Caucasians in the allele sizes. The decrease in average heterozygosity observed with STRP markers supports the view that the Pima Indians represent a more genetically homogenous population than Caucasians.

    The haplotypes at four polymorphic loci of the Y chromosome were determined in 245 Caucasian males from 12 subpopulations. The data show that haplotype radiation occurred among Caucasians. Haplotype radiation was accompanied by recurrent mutations at STR loci that caused partial randomization of haplotype structure. The present distribution of alleles at short tandem repeats (STRs) can be explained by a mutation pattern similar to those described for autosomal STRs. The degree of variation among groups of subpopulations was assayed by using the Analysis of Molecular Variance. The results confirm a faster divergence of the Y chromosome as compared to the rest of the genome. PMID:8587142

  16. The Effect of BCMO1 Gene Variants on Macular Pigment Optical Density in Young Healthy Caucasians

    Background: Serum lutein (L) and zeaxanthin (Z) positively correlate with macular pigment optical density (MPOD); hence, the latter is a valuable indirect tool for measuring L and Z content in the macula. L and Z have been attributed antioxidant capacity and protection from certain retinal diseases but their uptake within the eye is thought to depend on genetic, age, and environmental factors. In particular, gene variants within beta-carotene monooxygenase (BCMO1) are thought to modulate MPOD in the macula. Objectives: To determine the effect of BCMO1 single nucleotide polymorphisms (SNPs) rs11645428, rs6420424, and rs6564851 on MPOD in a cohort of young healthy participants of Caucasian origin with normal ocular health. Design: In this cohort study, MPOD was assessed in 46 healthy participants (22 male and 24 female) with a mean age of 23.8 ± 4.0 years (range 19–33). The three SNPs, rs11645428, rs6420424, rs6564851 that have established associations with MPOD were determined using MassEXTEND (hME) Sequenom assay. One-way analysis of variance was performed on groups segregated into homozygous and heterozygous BCMO1 genotypes. Correlations between body mass index (BMI), iris color, gender, central retinal thickness (CRT), diet, and MPOD were investigated. Results: Macular pigment optical density neither significantly varied with BCMO1 rs11645428 (F2,41 = 0.70, p = 0.503), rs6420424 (F2,41 = 0.21, p = 0.801) nor rs6464851 homozygous or heterozygous genotypes (F2,41 = 0,13, p = 0.88), in this young healthy cohort. The combination of these three SNPs into triple genotypes based on plasma conversion efficiency did not affect MPOD (F2,41 = 0.07, p = 0.9). There was a significant negative correlation with MPOD and CRT (r = −0.39, p = 0.01) but no significant correlation between BMI, iris color, gender, and MPOD. Conclusion: Our results indicate that macular pigment deposition within the central retina is not dependent on

    We report the clinical and genetic evaluation of a 2-year-old Greek female with striking phenotypic similarities to the three previously published cases of Okamoto syndrome. The main features were characteristic facies, cleft palate, generalized hypotonia, severe developmental delay, congenital hydronephrosis, and congenital heart defects. Routine chromosome testing and whole-genome high-resolution comparative genetic hybridization analysis were negative for any gross numerical or structural chromosome aberrations and for microdeletions/duplications of more than 3 million base pairs respectively. Fluorescence in situ hybridization analysis for 22q11.2 deletion and DNA analysis of the protein tyrosine phosphatase, non-receptor type II gene were normal, thus excluding DiGeorge and Noonan syndromes. Our patient did not show most of the cardinal features of Schinzel-Giedion, otopalatodigital, and C-trigonocephaly syndromes. Moreover, in our patient some new malformations were identified: unilateral kidney hypoplasia and severe anal stenosis. The latter was considered as pertinent and is described here to establish a wider clinical spectrum of Okamoto syndrome. At the age of 3 years 6 months the child continues to show severe growth failure and significant global developmental delay. For the practising paediatrician it is prudent to bear Okamoto syndrome in mind, especially in children with learning disability and a pattern of dysmorphic features. PMID:19046188

    As an infectious disease, typhus has triggered many epidemics during the course of wars and caused thousands of death all through the ages. The French physician Charles Nicolle (1886-1936) defined its agent as a louse transferring the disease from man to man in 1909 and was awarded the Nobel Prize in 1928. Many cases were reported during the 1st World War both in the European and the Ottoman armies; and one of the most severe epidemics broke in the Caucasian front; a great number of civilians and soldiers died at winter in 1914 and 1915. Lice had to be destroyed in order to prevent the epidemic, but etuves in the Caucasian front was too few to achieve it. Clothes were cleansed in ovens by means of a method proposed by Dr. Abdülkadir Noyan (1886-1977). On March 28, 1915 the first typhus vaccination, obtained from the infected blood of the patients, was applied by Dr. Tevfik Salim (Saklam) (1882-1963). In 1916 Dr. Ahmet Fikri Tüzer discovered a disinfection apparatus called "buğu sandiği" (vapour box) which was widely used in the Caucasian front after 1917. This apparatus was highly useful in controlling the typhus epidemics. 164 health officers lost their lifes in the Caucasian front between 1914-1918, in addition, 7310 military casualties were recorded from 1915 to the end of the war.

    1979-09-01

    The photoprotective role of melanin was evaluated by comparing the transmission of ultraviolet (UV) radiation through skin samples of blacks and Caucasians, using both biologic and spectroscopic techniques. UVA transmission was measured using fluoranthene, which causes a phototoxic response to UVA wavelength. UVB was measured by monitoring erythema produced by either a 150-watt xenon arc or FS-20 sunlamps. It was found that on the average, five times as much ultraviolet light (UVB and UVA) reaches the upper dermis of Caucasians as reaches that of blacks. Differences in transmission between the stratum corneum of blacks and of Caucasians were far less striking. The main site of UV filtration in Caucasians is the stratum corneum, whereas in blacks it is the malpighian layers. Melanin acts as a neutral density filter, reducing all wavelengths of light equally. The superior photoprotection of black epidermis is due not only to increased melanin content but also to other factors related to packaging and distribution of melanosomes. Not only are these data consistent with epidemiologic evidence, but they also may indicate why blacks are less disposed to phototoxic drug responses as well as less susceptible to acute and chronic actinic damage.

    The correlates of nonsuicidal self-injury (NSSI) among Asian and Caucasian university students; differences in the rates, frequency, forms, severity, and emotional contexts of NSSI among self-injuring students; and whether Asian students who are highly oriented toward Asian culture differed from those less oriented toward Asian culture in NSSI characteristics were investigated. University students (N = 931), including 360 Caucasian students (n = 95, 26.4%, with a history of ≥ 1 episode of NSSI) and 571 Asian students (n = 107, 18.7%, with a history of NSSI), completed questionnaires assessing NSSI, acculturation, and putative risk factors for NSSI. Caucasian students were more likely to report NSSI, particularly cutting behavior, self-injured with greater frequency and versatility, and reported greater increases in positively valenced, high arousal emotions following NSSI, compared to Asian students. Among Asian students, obsessive-compulsive symptoms, experiential avoidance, and anger suppression increased the likelihood of reporting a history of NSSI. Among Caucasian students, lack of emotional clarity and anger suppression increased likelihood of NSSI. Finally, some tentative findings suggested potentially important differences in rates and frequency of NSSI among Asian students who were highly oriented toward Asian culture compared with those less oriented toward Asian culture.

In this review, we systematically discuss publications that compare CAD biomarkers between Asians and Caucasians in the general population. A PubMed search yielded 5,570 hits, containing 59 articles describing 47 unique cohorts that directly compare Asians with Caucasians. Ten biomarkers were taken into account for this review: total cholesterol; triglycerides; high-density lipoprotein cholesterol; low-density lipoprotein cholesterol; C-reactive protein; glucose; insulin; glycated hemoglobin; fibrinogen; and plasminogen activator inhibitor-1. Triglycerides were 1.13-fold higher in South Asians than in Caucasians, and insulin levels were 1.33-fold higher. In Japanese and Chinese subjects, lower C-reactive protein levels were reported: 0.52 and 0.36-fold, respectively. Ethnicity-specific prognostic measures of CAD biomarkers were rarely reported. CAD biomarker levels differ between Asians and Caucasians and among Asian ethnic groups in population-based cohorts. The ethnicity-specific prognostic value of CAD biomarkers is yet to be determined.

    Incidence of infective endocarditis during pregnancy is around 0.006% with high maternal and fetal mortality. Bacillus cereus is an extremely rare cause for endocarditis in intravenous drug abusers (IVDA) or those with valvular disease or devices such as pacemakers. We report a case of B. cereus endocarditis, which, to the best of our knowledge, has never been reported in pregnancy. A 30-year-old, 25-week pregnant female presented with right shoulder pain, swelling and erythema on the lateral aspect of deltoid muscle from large abscess over her deltoid muscle. She was found to have a vegetation on the native tricuspid valve. Cultures from abscess fluid and blood cultures grew B. cereus, she was appropriately treated with antimicrobials and had favorable outcomes. There are <20 cases of B. cereus endocarditis reported but none during pregnancy. When cultures grow unusual organisms the case must be thoroughly investigated. This case illustrates a rare situation (endocarditis in pregnancy) with an unusual outcome (B. cereus) on an uncommon valve (tricuspid valve). PMID:26793477

    The elemental content of anagen hair fibers in a Caucasian population of healthy females and males in the age range 10-69 years was performed to constitute a baseline for further studies of pathological conditions. Proton induced X-ray emission (PIXE) analyses were performed on single hair fibers in triplicate from 103 individuals in order to determine sulfur, zinc, calcium, and chlorine content. The hair fibers were all anagen hairs collected from a site little influenced by genetic and hormonal influences 1.5 cm above the right ear of the probands. An area 5-8 mm from the follicle bottom was chosen for the analysis in all cases to minimize effect of hair-do contamination. The average sulfur content was 0.049 g/g and the average zinc content 170 micrograms/g. These results were not significantly influenced by chloroform/ethanol rinsing before analysis. The calcium and chlorine contents were 330 micrograms/g and 0.0033 g/g respectively. The latter data are expected to be more seriously influenced by external factors (e.g., contamination) than sulfur and zinc. No correlation between elemental concentration and sex was found for sulfur and zinc in the present material. PIXE analysis of single hair fibers yields valuable information on the elemental composition of hair fibers and can be rapidly and efficiently performed after simple mounting procedures.

    In three studies, implicit and explicit measures were used to examine the interconnections between ethnic and national identities among Latino Americans and Caucasian Americans. Consistently, Latino Americans as a group were conceived of as being less American than Caucasian Americans (Studies 1-3). This effect was exhibited by both Caucasian and Latino participants. Overall, Caucasian participants displayed a stronger national identification than Latino participants (Studies 2 and 3). In addition, ethnic American associations accounted for the strength of national identification for Caucasian participants, but not for Latino participants (Study 2). Finally, ethnic differences in national identification among individuals who exclude Latino Americans from the national identity emerged when persistent ethnic disparities were primed, but not when increasing equalities were stressed (Study 3). In sum, ethnic American associations account for the merging versus dissociation between ethnic and national identifications and reflect a long-standing ethnic hierarchy in American society.

    Caucasian populations have a higher prevalence of cardiovascular disease (CVD) when compared with their Chinese counterparts and CVD is associated with autonomic function. It is unknown whether autonomic function during exercise recovery differs between Caucasians and Chinese. The present study investigated autonomic recovery following an acute bout of treadmill exercise in healthy Caucasians and Chinese. Sixty-two participants (30 Caucasian and 32 Chinese, 50% male) performed an acute bout of treadmill exercise at 70% of heart rate reserve. Heart rate variability (HRV) and baroreflex sensitivity (BRS) were obtained during 5-min epochs at pre-exercise, 30-min, and 60-min post-exercise. HRV was assessed using frequency [natural logarithm of high (LnHF) and low frequency (LnLF) powers, normalized high (nHF) and low frequency (nLF) powers, and LF/HF ratio] and time domains [Root mean square of successive differences (RMSSD), natural logarithm of RMSSD (LnRMSSD) and R–R interval (RRI)]. Spontaneous BRS included both up-up and down-down sequences. At pre-exercise, no group differences were observed for any HR, HRV and BRS parameters. During exercise recovery, significant race-by-time interactions were observed for LnHF, nHF, nLF, LF/HF, LnRMSSD, RRI, HR, and BRS (up-up). The declines in LnHF, nHF, RMSSD, RRI and BRS (up-up) and the increases in LF/HF, nLF and HR were blunted in Chinese when compared to Caucasians from pre-exercise to 30-min to 60-min post-exercise. Chinese exhibited delayed autonomic recovery following an acute bout of treadmill exercise. This delayed autonomic recovery may result from greater sympathetic dominance and extended vagal withdrawal in Chinese.

    Soya isoflavones: genistein and daidzein are increasingly consumed in Western countries. Their beneficial effects are discussed considering nutrition and health in Asia. The present study aimed to check whether chronic ingestions, ethnic origin and dietary context can influence soya phyto-oestrogen bioavailability. Two prospective trials were carried out to blindly assess the pharmacokinetics after acute and chronic intake of soya-based cheese (45.97 (sd1.57) mg isoflavones) taken once a day for 10 d. Twelve healthy young Asians immersed for 2 months in France were randomised in a cross-over design to compare the influence of a Western v. Asian dietary context. The second trial partly nested in the first one, compared Asians under the Western diet to twelve healthy young male Caucasians under the same diet. All volunteers were non-equol producers. After an acute intake of soya in Western diet, Asians exhibited higher maximum concentration measured in plasma (Cmax) and area under the plasma concentration-time curve (AUC) for genistein and daidzein than Caucasians (P = 0.005, 0.006, 0.032 and 0.008, respectively). In Caucasians under Western diet, AUC and Cmax values significantly increased after chronic intake. This was not the case for daidzein in Asians whatever the dietary context. For the first time, it is evidenced that on acute intake of soya cheese, Asians absorb soya phyto-oestrogens better than Caucasians, regardless of whether the background diet is Western or Asian. On chronic ingestions, AUC and Cmax values were increased for daidzein and genistein in Caucasians but not in Asians. There are ethnic differences in isoflavone pharmacokinetic and bioavailability. This may influence health outcomes. PMID:19622188

    In a previous investigation, we demonstrated an increased progression of overt AIDS in the African American population compared to the Caucasian population as reflected by the significantly lower absolute number of CD4+ lymphocytes detected in the African American population in an earlier study. The present study elucidates some of the possible genetic factors which may contribute to disease association or protection against HIV infection. The HLA phenotypes expressed as A, B, C, DR and DQw antigens were revealed by the Amos-modified typing procedure. NIH scoring was utilized to designate positive cells taking up trypan blue. A test of proportion equivalent to the chi 2 approximation was used to compare the disease population (n = 62; 38 African Americans, 24 Caucasians) to race-matched normal heterosexual local controls (323 African Americans, 412 Caucasians). Significant p values were corrected for the number of HLA antigens tested. HLA markers associated with possible protection from infection for African Americans were Cw4 and DRw6, whereas Caucasians expressed none. Disease association markers present in the African American population were A31, B35, Cw6, Cw7, DR5, DR6, DRw11, DRw12, DQw6 and DQw7, whereas in the Caucasian population A28, Aw66, Aw48, Bw65, Bw70, Cw7, DRw10, DRw12, DQw6 and DQw7 were demonstrated. The highest phenotypic frequency for a disease association marker in the study was for HLA-DR5 (62.9%) in the HIV-infected African American population without Kaposi's sarcoma compared to a frequency of 28.9% for the regional control group (p = 0.0012). We conclude that genetic factors do have a role in HIV infection since only 50-60% of those exposed to the AIDS virus will become infected. PMID:1910527

    Background Killer cell immunoglobulin-like receptors (KIRs) are a family of inhibitory and activatory receptors that are expressed by most natural killer (NK) cells. The KIR gene family is polymorphic: genomic diversity is achieved through differences in gene content and allelic polymorphism. The number of KIR loci has been reported to vary among individuals, resulting in different KIR haplotypes. In this study we report the genotypic structure of KIRs in 217 unrelated healthy Italian individuals from 22 immunogenetics laboratories, located in the northern, central and southern regions of Italy. Methods Two hundred and seventeen DNA samples were studied by a low resolution PCR-SSP kit designed to identify all KIR genes. Results All 17 KIR genes were observed in the population with different frequencies than other Caucasian and non-Caucasian populations; framework genes KIR3DL3, KIR3DP1, KIR2DL4 and KIR3DL2 were present in all individuals. Sixty-five different profiles were found in this Italian population study. Haplotype A remains the most prevalent and genotype 1, with a frequency of 28.5%, is the most commonly observed in the Italian population. Conclusion The Italian Caucasian population shows polymorphism of the KIR gene family like other Caucasian and non-Caucasian populations. Although 64 genotypes have been observed, genotype 1 remains the most frequent as already observed in other populations. Such knowledge of the KIR gene distribution in populations is very useful in the study of associations with diseases and in selection of donors for haploidentical bone marrow transplantation.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    Shuttlesworth, Mary E; Zotter, Deanne

    2011-01-01

    The influential roles of culture and ethnic identity are frequently cited in developing disordered eating and body dissatisfaction, constituting both protective and risk factors. For African American women, strongly identifying with African American cultural beauty ideals may protect against disordered eating to lose weight, but may actually increase risk in development of disordered eating directed at weight gain, such as binge eating. This study compares African American and Caucasian women on disordered eating measures, positing that African American women show greater risk for binge eating due to the impact of ethnic identity on body dissatisfaction. Findings indicate low levels of ethnic identity represent a risk factor for African American women, increasing the likelihood of showing greater binge eating and bulimic pathology. In Caucasian women, high levels of ethnic identity constitute a risk factor, leading to higher levels of both binge eating and global eating pathology. Implications for prevention and treatment are discussed. PMID:22073427

    There have been a few epidemiological studies reporting VDR polymorphisms including Fok1, Bsm1, Apa1 and Taq1with breast cancer incidence and therefore risk. The results however are controversial, often due to smaller sample size. Concerning most of the studies were performed on Caucasian women, we conducted this comprehensive meta-analysis encompassing 38,151 cases and 47,546 controls (Fok1: 13,152 cases, 17,443 controls; Bsm1: 14,755 cases, 18,633 controls; Apa1: 3080 cases, 3412 controls; Taq1: 7164 cases, 8068 controls) to better understand roles of the polymorphisms in breast cancer development among Caucasian population. We did not find any association of the most controversial genotype Fok1 with breast cancer risk in Caucasian women (ff vs. FF: OR = 1.05, 95% CI = 0.95-1.22, P = 0.32 for heterogeneity; ff vs. Ff: OR = 1.05, 95% CI = 0.94-1.17, P = 0.40; ff vs. Ff + FF: OR = 1.07, 95% CI = 0.95-1.14, P = 0.37 and ff + Ff vs. FF: OR = 1.04, 95% CI = 0.99-1.09, P = 0.23). For Bsm1, Apa1 and Taq1, no significant association was also not found in the homozygote comparison, heterozygote comparison, recessive and dominant models respectively. In conclusion, the current analysis suggested that the four polymorphisms (Fok1, Bsm1, Apa1 and Taq1) of VDR may be not associated with breast cancer risk in Caucasian women. PMID:25606388

    As computer usage becomes mandatory on college campuses across the world, the issue of examining students' attitudes toward computers becomes very important. The major goal of this study was to examine the relationship between gender and ethnicity and African American and Caucasian college students attitudes toward computers. The Computer Attitude Scale instrument was used to measure the students' attitudes. During the Summer of the 1996 academic year, a university in the southeastern United States was selected to participate in this study. A total of 230 African American and Caucasian undergraduate students participated in the study. The students were pre-tested during the first week of the semester to access their initial computer attitudes. The students were enrolled in one of the mandatory computer literacy courses (Computer Literacy Awareness Course or C, Pascal or FORTRAN Programming Course) for 12 weeks. There were a total of seven different instructors for the courses. During the 12th week of class, the students were post-tested to access their computer attitudes after completing one of the computer literacy courses. Results were analyzed using ANCOVA. While both African Americans and Caucasian students showed a slight increase in their attitudes toward computers after completing the course, no significant difference between the groups was found. However, all groups were found to have positive attitudes toward computers in general. Data analysis also indicated no significant gender difference among African American and Caucasian undergraduate students. This confirmed findings of previous studies in which no significant gender difference was found to exist among college students.

  17. Risk factors for breast cancer in postmenopausal Caucasian and Chinese-Canadian women

    PubMed Central

    2010-01-01

    Introduction Striking differences exist between countries in the incidence of breast cancer. The causes of these differences are unknown, but because incidence rates change in migrants, they are thought to be due to lifestyle rather than genetic differences. The goal of this cross-sectional study was to examine breast cancer risk factors in populations with different risks for breast cancer. Methods We compared breast cancer risk factors among three groups of postmenopausal Canadian women at substantially different risk of developing breast cancer - Caucasians (N = 413), Chinese women born in the West or who migrated to the West before age 21 (N = 216), and recent Chinese migrants (N = 421). Information on risk factors and dietary acculturation were collected by telephone interviews using questionnaires, and anthropometric measurements were taken at a home visit. Results Compared to Caucasians, recent Chinese migrants weighed on average 14 kg less, were 6 cm shorter, had menarche a year later, were more often parous, less often had a family history of breast cancer or a benign breast biopsy, a higher Chinese dietary score, and a lower Western dietary score. For most of these variables, Western born Chinese and early Chinese migrants had values intermediate between those of Caucasians and recent Chinese migrants. We estimated five-year absolute risks for breast cancer using the Gail Model and found that risk estimates in Caucasians would be reduced by only 11% if they had the risk factor profile of recent Chinese migrants for the risk factors in the Gail Model. Conclusions Our results suggest that in addition to the risk factors in the Gail Model, there likely are other factors that also contribute to the large difference in breast cancer risk between Canada and China.

    We have reported that lactobionic acid is produced from lactose by Acetobacter orientalis in traditional Caucasian fermented milk. To maximize the application of lactobionic acid, we investigated favorable conditions for the preparation of resting A. orientalis cells and lactose oxidation. The resting cells, prepared under the most favorable conditions, effectively oxidized 2-10% lactose at 97.2 to 99.7 mol % yield. PMID:22313756

    Objectives The objective of this study was to determine whether clinical, environmental, and genetic factors can be used to develop dosing algorithms for Caucasians and African Americans that perform better than giving empirical 5 mg/day. Methods From April 2002 through December 2005, 259 warfarin initiators were prospectively followed until they reached maintenance dose. Results The Caucasian algorithm included 11 variables (R2=0.43). This model (51% within 1 mg) performed better compared with 5 mg/day (29% within 5±1 mg). The African American algorithm included 10 variables (R2=0.28). This model predicted 37% of doses within 1 mg of the observed dose; a small improvement compared with 5 mg/day (34%). These results were similar to the results we obtained from testing other (published) algorithms. Conclusions The dosing algorithms in Caucasians explained <45% of the variability and the algorithms in African Americans performed only marginally better than giving 5 mg empirically. PMID:18596683

    Large-scale genome-wide association studies (GWAS) identified three single nucleotide polymorphisms rs11136000, rs2279590, and rs9331888 in CLU gene to be significantly associated with Alzheimer's disease (AD) in Caucasian ancestry. Both rs11136000 and rs2279590 variants were successfully replicated in Asian population. However, previous studies reported either a weak association or no association between rs9331888 polymorphism and AD in Asian population. Here, we searched the PubMed, AlzGene, and Google Scholar databases. We selected 12 independent studies that evaluated the association between the rs9331888 polymorphism and AD using a case-control design. Using an additive model, we did not identify significant heterogeneity among these 12 studies. We observed significant association between rs9331888 polymorphism and AD in pooled populations (P = 2.26E - 07, odds ratio (OR) = 1.10, 95 % confidence interval (CI) 1.06-1.14). In subgroup analysis, we did not identify significant heterogeneity in both Asian and Caucasian populations. We identified significant association in Caucasian population (P = 1.67E - 08, OR = 1.13, 95 % CI 1.08-1.18) but not in East Asian population (P = 0.49, OR = 1.02, 95 % CI 0.96-1.10). PMID:25633098

    The aims of this study were to determine whether disparities in waiting list outcomes exist for Hispanics and African Americans during the post-MELD era, and to investigate interactions between disparities and geography. Scientific Registry of Transplant Recipients data were used to compare Hispanics and African Americans to Caucasians listed between 2003 and 2008. Endpoints included (i) receipt of a liver transplant and (ii) death or removal from the waiting list for being too sick or medically unsuitable. Adjustment for possible confounders was performed using multivariate Cox regression, with adjustment for geographic variation using a fixed-effects multilevel model. In multivariate analysis, African Americans have similar hazard of transplantation and death/removal as Caucasians during the post-MELD era. However, Hispanics are less likely to receive a transplant than Caucasians despite adjustment for potential confounders (HR 0.80, 95% CI 0.77-0.83), while having a similar hazard of death/removal. This effect disappeared after adjusting for unequal regional distribution of Hispanics, who represent 8% of patients in donation service areas (DSAs) having median waiting times of < or = 155 days versus 19% in DSAs with median waiting times of >155 days. In conclusion, disparities in liver transplantation exist for Hispanics during the post-MELD era, caused by geographic variation in organ availability. PMID:19624565

    Race categorization of faces is a fast and automatic process and is known to affect further face processing profoundly and at earliest stages. Whether processing of own- and other-race faces might rely on different facial cues, as indicated by diverging viewing behavior, is much under debate. We therefore aimed to investigate two open questions in our study: (1) Do observers consider information from distinct facial features informative for race categorization or do they prefer to gain global face information by fixating the geometrical center of the face? (2) Does the fixation pattern, or, if facial features are considered relevant, do these features differ between own- and other-race faces? We used eye tracking to test where European observers look when viewing Asian and Caucasian faces in a race categorization task. Importantly, in order to disentangle centrally located fixations from those towards individual facial features, we presented faces in frontal, half-profile and profile views. We found that observers showed no general bias towards looking at the geometrical center of faces, but rather directed their first fixations towards distinct facial features, regardless of face race. However, participants looked at the eyes more often in Caucasian faces than in Asian faces, and there were significantly more fixations to the nose for Asian compared to Caucasian faces. Thus, observers rely on information from distinct facial features rather than facial information gained by centrally fixating the face. To what extent specific features are looked at is determined by the face's race. PMID:24796509

    PURPOSE: This exploratory study examined perceptions and beliefs of African Americans and Caucasians related to cancer care. Understanding belief systems and cultures optimizes cancer treatment and care delivery to ethnic minority individuals. PATIENTS AND METHODS: Focus groups were conducted with 39 African-American and Caucasian cancer patients. Data analysis included whole group analysis with a team of five researchers. RESULTS: Regardless of ethnicity, cancer patients share many of the same emotions and experiences, and want complete information and quality care. Differences were also apparent. African-American participants were more likely to report increased religious behaviors, believe that healthcare providers demonstrate care with simple actions and provision of practical assistance, and use church and community information sources. Caucasian participants were more likely to report spiritual but not overtly religious changes, and depend on healthcare providers for information. CONCLUSION: Understanding how culture colors perceptions, communication and information requirements is critical to providing effective care to ethnically diverse cancer patients. Findings have implications for professionals understanding ways patients seek information, the role of spirituality and religion in care, and ways healthcare providers demonstrate care.

    A large-scale study of facial soft tissue depths of Caucasian adults was conducted. Over a 2-years period, 967 Caucasian subjects of both sexes, varying age and varying body mass index (BMI) were studied. A user-friendly and mobile ultrasound-based system was used to measure, in about 20min per subject, the soft tissue thickness at 52 facial landmarks including most of the landmarks used in previous studies. This system was previously validated on repeatability and accuracy [S. De Greef, P. Claes, W. Mollemans, M. Loubele, D. Vandermeulen, P. Suetens, G. Willems, Semi-automated ultrasound facial soft tissue depth registration: method and validation. J. Forensic Sci. 50 (2005)]. The data of 510 women and 457 men were analyzed in order to update facial soft tissue depth charts of the contemporary Caucasian adult. Tables with the average thickness values for each landmark as well as the standard deviation and range, tabulated according to gender, age and BMI are reported. In addition, for each landmark and for both sexes separately, a multiple linear regression of thickness versus age and BMI is calculated. The lateral asymmetry of the face was analysed on an initial subset of 588 subjects showing negligible differences and thus warranting the unilateral measurements of the remaining subjects. The new dataset was statistically compared to three datasets for the Caucasian adults: the traditional datasets of Rhine and Moore [J.S. Rhine, C.E. Moore, Tables of facial tissue thickness of American Caucasoids in forensic anthropology. Maxwell Museum Technical series 1 (1984)] and Helmer [R. Helmer, Schädelidentifizierung durch elektronische bildmischung, Kriminalistik Verlag GmbH, Heidelberg, 1984] together with the most recent in vivo study by Manhein et al. [M.H. Manhein, G.A. Listi, R.E. Barsley, R. Musselman, N.E. Barrow, D.H. Ubelbaker, In vivo facial tissue depth measurements for children and adults. J. Forensic Sci. 45 (2000) 48-60]. The large-scale database

    South Asians are at higher risk than White Caucasians for the development of obesity and obesity-related non-communicable diseases (OR-NCDs), including insulin resistance, the metabolic syndrome, type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). Rapid nutrition and lifestyle transitions have contributed to acceleration of OR-NCDs in South Asians. Differences in determinants and associated factors for OR-NCDs between South Asians and White Caucasians include body phenotype (high body fat, high truncal, subcutaneous and intra-abdominal fat, and low muscle mass), biochemical parameters (hyperinsulinemia, hyperglycemia, dyslipidemia, hyperleptinemia, low levels of adiponectin and high levels of C-reactive protein), procoagulant state and endothelial dysfunction. Higher prevalence, earlier onset and increased complications of T2DM and CHD are often seen at lower levels of body mass index (BMI) and waist circumference (WC) in South Asians than White Caucasians. In view of these data, lower cut-offs for obesity and abdominal obesity have been advocated for Asian Indians (BMI; overweight >23 to 24.9 kg m(-2) and obesity ≥ 25 kg m(-2); and WC; men ≥ 90 cm and women ≥ 80 cm, respectively). Imbalanced nutrition, physical inactivity, perinatal adverse events and genetic differences are also important contributory factors. Other differences between South Asians and White Caucasians include lower disease awareness and health-seeking behavior, delayed diagnosis due to atypical presentation and language barriers, and religious and sociocultural factors. All these factors result in poorer prevention, less aggressive therapy, poorer response to medical and surgical interventions, and higher morbidity and mortality in the former. Finally, differences in response to pharmacological agents may exist between South Asians and White Caucasians, although these have been inadequately studied. In view of these data, prevention and management strategies should be more

    The intravenous (iv) formulation of levetiracetam has been available in clinical practice worldwide for several years, but not in Japan. Two open-label studies were conducted: Study A evaluated the bioequivalence of iv and oral tablet formulations in healthy Japanese volunteers; and Study B subsequently compared the pharmacokinetics of iv levetiracetam in healthy Japanese and Caucasian volunteers. Study A had a randomised, two-way crossover design; a single 1,500 mg levetiracetam dose was administered as a 15-min iv infusion and as 3 × 500 mg oral tablets to Japanese volunteers. In Study B, 1,500 mg levetiracetam was administered as single and repeated 15-min iv infusions to Japanese and Caucasian volunteers. Overall, 26/27 volunteers completed Study A and 32/32 (16 Japanese; 16 Caucasian) completed Study B. In Study A, the point estimate and 90 % confidence interval (CI) for the geometric least squares mean (LSM) ratio (iv vs oral) were fully included within the acceptance range for bioequivalence (0.85-1.25) for the area under plasma concentration-time curve from 0 to last quantifiable observation (AUClast 0.97 [0.95, 0.99]), but not for the maximum plasma concentration (C max 1.64 [1.47, 1.83]). In Study B, after a single iv infusion, the point estimates (90 % CI) for the geometric LSM ratio (Japanese vs Caucasian) for body weight-normalised C max and AUClast were 1.21 (1.07, 1.36) and 0.97 (0.90, 1.04), respectively. Corresponding values after repeated iv infusions were C max,ss 1.01 (0.91, 1.12) and AUCτ,ss 0.89 (0.83, 0.96). Levetiracetam was well tolerated in both studies. Study A did not demonstrate the bioequivalence of single doses of levetiracetam 1,500 mg administered as an iv infusion and as oral tablets in healthy Japanese adults. Study B, however, showed that pharmacokinetic profiles were generally similar between Japanese and Caucasian adults after single and repeated iv infusions of levetiracetam 1,500 mg. PMID:25283522

    OBJECTIVE This cross-sectional clinical study compared the pathophysiology of type 2 diabetes in Japanese and Caucasians and investigated the role of demographic, genetic, and lifestyle-related risk factors for insulin resistance and β-cell response. RESEARCH DESIGN AND METHODS A total of 120 Japanese and 150 Caucasians were enrolled to obtain comparable distributions of high/low BMI values across glucose tolerance states (normal glucose tolerance, impaired glucose tolerance, and type 2 diabetes), which were assessed by oral glucose tolerance tests. BMI in the two cohorts was distributed around the two regional cutoff values for obesity. RESULTS Insulin sensitivity was higher in Japanese compared with Caucasians, as indicated by the homeostatic model assessment of insulin resistance and Matsuda indices, whereas β-cell response was higher in Caucasians, as measured by homeostatic model assessment of β-cell function, the insulinogenic indices, and insulin secretion ratios. Disposition indices were similar for Japanese and Caucasians at all glucose tolerance states, indicating similar β-cell response relative to the degree of insulin resistance. The main determinants for differences in metabolic indices were measures of body composition, such as BMI and distribution of adipose tissue. Differences in β-cell response between Japanese and Caucasians were not statistically significant following adjustment by differences in BMI. CONCLUSIONS Our study showed similar disposition indices in Japanese and Caucasians and that the major part of the differences in insulin sensitivity and β-cell response between Japanese and Caucasians can be explained by differences in body composition.

    PURPOSE: To explore attitudes and perceptions of obesity, and identify preferences for weight-management interventions by African-American and Caucasian women who were followed in general internal medicine clinics. PROCEDURE: Surveys exploring these issues were mailed to African-American (n=240) and Caucasian (n=240) women with a BMI of > or =30. MAIN FINDINGS: Caucasian women felt past weight-loss efforts were helped by weight-loss programs significantly more than African-American women (P<0.001); African-American women were more likely to feel that their cultural background contributed to their weight gain than did Caucasian women (P=0.001). African-American women expressed a higher need for one-on-one counseling with their physician (P<0.001) as well as group meetings with the dietician, physician and other women (P=0.004) than did Caucasian women. African-American women also felt it was more important for weight-loss programs to have information on food common to their culture than did Caucasian women (P<0.001). CONCLUSIONS: Differences in cultural background and preferences about weight loss interventions have important policy implications for how the U.S. healthcare system provides care to an ever-increasing multicultural population with a national epidemic such as obesity.

    Objectives To ascertain whether non-Hispanic African American and Caucasian chronic pain sufferers differ or converge in their self-reports of pain experience and pain adjustment. Research Design A telephone survey of U.S. English-speaking adults selected via random-digit dialing procedures and constrained to locate persons with chronic pain within selected gender by age groupings. Subjects A national sample of 2,407 participants contained a total of 214 non-Hispanic African Americans. A sample of 214 non-Hispanic Caucasians was randomly selected from the larger set of 1,935 Caucasian participants to serve as a comparison group for the present study. Measures Participants provided responses to interviewer questions that assessed pain experience (severity, interference, and emotional burden) and psychosocial outcomes (coping, attitudes and beliefs, catastrophizing, social support and hindrance, pain’s interference with daily life activities, treatment status, and medication taking). Results Although African American and Caucasian adults with chronic pain did not differ significantly in pain severity, interference, emotional burden, or current treatment status, multivariate analyses revealed differences in several domains of psychosocial functioning. Compared to Caucasians, African Americans reported greater pain-related interference with daily living, deficiencies in coping, and counterproductive attitudes and beliefs. African Americans also reported greater impatience and insensitivity from the most important person in their lives. Conclusions Psychosocial dimensions of chronic pain differed between community-residing African American and Caucasian adults surveyed as part of a national sample. PMID:15669950

    Background: Underweight as a public health problem in young women is associated with nutritional deficiencies, menstrual irregularity, eating disorders, reduced fertility, etc. Since resting metabolic rate (RMR) is a necessary component in the development of nutrition support therapy, therefore we determined the accuracy of commonly used predictive equations against RMR measured by indirect calorimetry among healthy young underweight females. Methods: This cross-sectional study was conducted on 104 underweight females aged 18–30 years old with body mass index (BMI) <18.5 kg/m2 in 2013. After collecting anthropometric data, body composition was measured by bioelectric impedance analysis (BIA). RMR was measured by using indirect calorimetry (FitMate™) and was estimated by 10 commonly used predictive equations. Comparisons were conducted using paired t-test. The accuracy of the RMR equations was evaluated on the basis of the percentage of subjects’ predicted RMR within 10% of measured RMR. Results: The mean BMI of subjects was 17.3±1.3 kg/m2. The measured RMR ranged 736–1490 kcal/day (mean 1084.7±175 kcal/day). Findings indicated that except Muller and Abbreviation, other equations significantly over estimated RMR, compared to measured value (P<0.05). As an individual prediction accuracy, these predictive equations showed poor performance with the highest accuracy rate of 54.8% for Muller equation (22.1% under and 23.1% over-prediction) and 43.3% for Abbreviation equation (31.7% under and 25% over-prediction), the percentage bias was 1.8% and 0.63% and RMSE was 162 and 173 kcal/d, respectively. Conclusion: Although Muller equation gave fairly acceptable prediction, more suitable new equations are needed to be developed to help better management of nutritional plans in young underweight people.

    Previous studies have reported that 3- to 4-month-olds show a visual preference for faces of the same gender as their primary caregiver (e.g., Quinn et al., 2002). In addition, this gender preference has been observed for own-race faces, but not for other-race faces (Quinn et al., 2008). However, most of the studies of face gender preference have focused on infants at 3–4 months. Development of gender preference in later infancy is still unclear. Moreover, all of these studies were conducted with Caucasian infants from Western countries. It is thus unknown whether a gender preference that is limited to own-race faces can be generalized to infants from other racial groups and different cultures with distinct caregiving practices. The current study investigated the face gender preferences of Asian infants presented with male versus female face pairs from Asian and Caucasian races at 3, 6, and 9 months and the role of caregiving arrangements in eliciting those preferences. The results showed an own-race female face preference in 3- and 6-month-olds, but not in 9-month-olds. Moreover, the downturn in the female face preference correlated with the cumulative male face experience obtained in caregiving practices. In contrast, no gender preference or correlation between gender preference and face experience was found for other-race Caucasian faces at any age. The data indicate that the face gender preference is not specifically rooted in Western cultural caregiving practices. In addition, the race dependency of the effect previously observed for Caucasian infants reared by Caucasian caregivers looking at Caucasian but not Asian faces extends to Asian infants reared by Asian caregivers looking at Asian but not Caucasian faces. The findings also provide additional support for an experiential basis for the gender preference, and in particular suggest that cumulative male face experience plays a role in inducing a downturn in the preference in older infants.

    There is still a paucity of data on how breast cancer (BC) biology influences outcomes in elderly patients. We evaluated whether ER/PR/HER2 subtype and TNM stage of invasive BC had a significant impact on overall survival (OS) in a cohort of 232 elderly Caucasian female patients (≥70 year old (y/o)) from our institution over a ten-year interval (January 1998-July 2008). Five ER/PR/HER2 BC subtypes classified per 2011 St. Gallen International Expert Consensus recommendations were further subclassified into three subtypes (traditionally considered "favorable" subtype-ER+/PR+/HER2-, and traditionally considered "unfavorable" BC subtypes: HER2+ and triple negative). OS was measured comparing these categories using Kaplan Meier curves and Cox regression analysis, when controlled for TNM stage. The majority of our patients (178/232 = 76.8%) were of the "favorable" BC subtype; 23.2% patients were with "unfavorable" subtype (HER2+ = 12% (28/232) and triple negative = 11.2% (26/232)). Although a trend for better OS was noted in HER2+ patients (68%) vs. 56% in ER+/PR+ HER2- or 58% in triple negative patients, "favorable" BC subtype was not significantly predictive of better OS (p = 0.285). TNM stage was predictive of OS (p < 0.001). These results are similar to our published studies on Caucasian BC patients of all ages in which ER/PR/HER2 status was not predictive of OS, irrespective of classification system used. PMID:26264027

    Background: Phase-IV, open-label, single-arm study (NCT01203917) to assess efficacy and safety/tolerability of first-line gefitinib in Caucasian patients with stage IIIA/B/IV, epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC). Methods: Treatment: gefitinib 250 mg day−1 until progression. Primary endpoint: objective response rate (ORR). Secondary endpoints: disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and safety/tolerability. Pre-planned exploratory objective: EGFR mutation analysis in matched tumour and plasma samples. Results: Of 1060 screened patients with NSCLC (859 known mutation status; 118 positive, mutation frequency 14%), 106 with EGFR sensitising mutations were enrolled (female 70.8% adenocarcinoma 97.2% never-smoker 64.2%). At data cutoff: ORR 69.8% (95% confidence interval (CI) 60.5–77.7), DCR 90.6% (95% CI 83.5–94.8), median PFS 9.7 months (95% CI 8.5–11.0), median OS 19.2 months (95% CI 17.0–NC; 27% maturity). Most common adverse events (AEs; any grade): rash (44.9%), diarrhoea (30.8%); CTC (Common Toxicity Criteria) grade 3/4 AEs: 15% SAEs: 19%. Baseline plasma 1 samples were available in 803 patients (784 known mutation status; 82 positive; mutation frequency 10%). Plasma 1 EGFR mutation test sensitivity: 65.7% (95% CI 55.8–74.7). Conclusion: First-line gefitinib was effective and well tolerated in Caucasian patients with EGFR mutation-positive NSCLC. Plasma samples could be considered for mutation analysis if tumour tissue is unavailable. PMID:24263064

    This cross-sectional study examines health information-seeking behaviors and access to and use of technology among rural African Americans, Caucasians, and Hispanics. There was a low level of health information seeking across the sample. Few used smartphones or tablets and did not endorse receiving health information from their health care provider by e-mail. Printed materials remained a source of health information as did friends and family. Information should be shared using multiple platforms including more passive methods such as television and radio. More research is needed to ensure the health literacy, numeracy, and ability to navigate the online environment. PMID:26333608

    Coping strategies and optimism have significant effects on the health of older women. Culture affects coping behaviors used to deal with stress. We examined the relationship between optimism and coping strategies used to manage daily stress and health among community-dwelling Caucasian, Korean American, and African American women. Data were collected from 373 women over the age of 65. Results showed that each group used different coping strategies. The more optimistic used more problem-focused and adaptive copings, while the less optimistic employed more avoidant copings. Differences in cultural background and individual levels of optimism guided their coping strategies. PMID:23865863

    Anthropological investigations have shown that representatives of European and mongoloid races lived in the river basin of Aragvi from late Stone Age. These data confirm a viewpoint of academician V.P. Alekssev (1974) that population of the Caucasus was compound in race terms from the ancient times. Situation of the Caucasian peoples on the dendrogrammes built corresponds in general to the data of national anthropologists. Clusterization of other europeoid ethnic groups also corresponds in general to the anthropological and historical data and confirms hypothesis which we have set up earlier about differentiation of europeoids, north mongoloids and amerinds of the same population which lived in Asia in palaeolith.

    2014-01-01

    Background This study compared efficacy and safety of the selective relaxant binding agent sugammadex (2 mg/kg) with neostigmine (50 μg/kg) for neuromuscular blockade (NMB) reversal in Chinese and Caucasian subjects. Methods This was a randomized, active-controlled, multicenter, safety-assessor-blinded study (NCT00825812) in American Society of Anesthesiologists Class 1-3 subjects undergoing surgery with propofol anesthesia. Rocuronium 0.6 mg/kg was administered for endotracheal intubation, with 0.1–0.2 mg/kg maintenance doses given as required. NMB was monitored using TOF-Watch® SX. At second twitch reappearance, after last rocuronium dose, subjects received sugammadex 2 mg/kg or neostigmine 50 μg/kg plus atropine 10–20 μg/kg, according to randomization. Primary efficacy variable was time from sugammadex/neostigmine to recovery of the train-of-four (TOF) ratio to 0.9. Results Overall, 230 Chinese subjects (sugammadex, n = 119, neostigmine, n = 111); and 59 Caucasian subjects (sugammadex, n = 29, neostigmine, n = 30) had evaluable data. Geometric mean (95% CI) time to recovery to TOF ratio 0.9 was 1.6 (1.5–1.7) min with sugammadex vs 9.1 (8.0–10.3) min with neostigmine in Chinese subjects. Corresponding times for Caucasian subjects were 1.4 (1.3–1.5) min and 6.7 (5.5–8.0) min, respectively. Sugammadex 2 mg/kg was generally well tolerated, with no serious adverse events reported. There was no residual NMB or recurrence of NMB. Conclusion Both Chinese and Caucasian subjects recovered from NMB significantly faster after sugammadex 2 mg/kg vs neostigmine 50 μg/kg, with a ~5.7 times (p < 0.0001) faster recovery with sugammadex vs neostigmine in Chinese subjects.

    Aims Compare subjective responses to alcohol among Han Chinese and Caucasian American males. Design Double-blinded, placebo-controlled human laboratory design. Participants completed three randomized experimental sessions with high and low alcohol, and placebo beverage. Setting Chinese participants were examined at Xinjiang Medical University, China. Caucasian participants were examined at the University of Chicago, USA. Participants 70 Han Chinese (35 heavy/35 light drinkers) and 75 Caucasian Americans (43 heavy/32 light drinkers). Measurements Breath alcohol concentration (BrAC) and the Stimulation and Sedation subscales of the Biphasic Alcohol Effects Scale were assessed at pre-drink baseline and four timepoints after beverage consumption. The Like and Want subscales of the Drug Effects Questionnaire were also assessed at the post-drink assessments. Findings Comparisons with light drinkers showed that high and low dose alcohol produced decreases in stimulation, liking, and wanting in Chinese vs. Caucasians (ps<.05), and dose-dependent increases in sedation in both groups (ps<0.001). Among heavy drinkers, high dose alcohol produced higher stimulation (p<0.001) but with concomitant higher sedation for both doses (ps<0.05) for Chinese vs. Caucasians. Alcohol also demonstrated significantly lower liking (ps<0.001) in Chinese vs. Caucasian heavy drinkers for both doses. Interestingly, both groups showed dose dependent increases in wanting relative to placebo (ps<0.05), but the magnitude of the increase was lower in Chinese. Conclusions Stimulating effects of alcohol are predominant in Chinese male binge drinkers, as has been found in Caucasians, but with less hedonic and motivational reward, potentially explaining some of the lower risk for alcohol disorders in Asian subgroups.

    Takayasu's arteritis (TA) and Crohn's disease (CD) are chronic inflammatory granulomatous disorders of undetermined etiology. TA is a large vessel vasculitis with a predilection for the aorta and its branches in young women of Asian descent; whereas CD has characteristic gastrointestinal manifestations more prevalent in young Caucasians. We describe a case of both diseases in a young Hispanic female, review the literature, and impart new insight on possible genetic linkage and the role of interleukin 12 B (IL-12B) as the common autoimmune mechanism and potential therapeutic target in this rare disease combination.

    Dapoxetine is a short-acting selective serotonin reuptake inhibitor developed for the on-demand treatment of premature ejaculation and is approved in some European Union countries, as well as Mexico and Korea, for this indication. The pharmacokinetics of dapoxetine 30 mg and 60 mg in healthy Chinese (single dose), Japanese, and Caucasian men (single and multiple dose) were assessed in 2 studies. In the 3 ethnic groups, dapoxetine was rapidly absorbed following oral administration, with peak plasma concentrations evident approximately 1 hour after dosing, independent of dose, dosing frequency (single or multiple dosing), or ethnicity. Dapoxetine was eliminated in a biphasic manner with an apparent mean terminal half-life of 14 to 17 hours. There was a dose-proportional increase in dapoxetine maximum plasma concentration (C(max)) and area under concentration-time curves (AUCs). The single-dose pharmacokinetic parameters of dapoxetine metabolites were also similar for the 3 ethnic groups, as were the pharmacokinetics of dapoxetine and its metabolites following single and multiple dosing in Caucasian and Japanese men. Dapoxetine was well tolerated by all 3 ethnic groups. PMID:20097934

    We analyse the effects of the air ambient temperature on the airflow across a Caucasian nasal cavity under different ambient temperatures using CFD simulations. A three-dimensional nasal model was constructed from high-resolution computed tomography images for a nasal cavity from a Caucasian male adult. An exhaustive parametric study was performed to analyse the laminar-compressible flow driven by two different pressure drops between the nostrils and the nasopharynx, which induced calm breathing flow rates ࣈ 5.7 L/min and ࣈ 11.3 L/min. The inlet air temperature covered the range - 10(o) C ⩽ To ⩽50(o) C. We observed that, keeping constant the wall temperature of the nasal cavity at 37(o) C, the ambient temperature affects mainly the airflow velocity into the valve region. Surprisingly, we found an excellent linear relationship between the ambient temperature and the air average temperature reached at different cross sections, independently of the pressure drop applied. Finally, we have also observed that the spatial evolution of the mean temperature data along the nasal cavity can be collapsed for all ambient temperatures analysed with the introduction of suitable dimensionless variables, and this evolution can be modelled with the help of hyperbolic functions, which are based on the heat exchanger theory.

    BACKGROUND AND OBJECTIVE To compare Asian and Caucasian anterior segment dimensions measured by optical coherence tomography (OCT). PATIENTS AND METHODS Anterior segment OCT images were obtained in normal subjects. Four line scans were acquired at the 90°, 45°, 0°, and 135° meridians of each eye. Computer calipers acquired anterior segment dimensions of corneal diameter, anterior chamber width, corneal vault, and anterior chamber depth on OCT images. Univariate and multivariate analyses were performed to assess correlations. RESULTS Corneal diameter was 0.5 mm narrower (P < .01), anterior chamber width was 0.46 mm narrower (P < .01), and corneal vault was 0.22 mm lower (P < .01) in Asian eyes. All anterior segment dimensions decreased with age. CONCLUSION Asian eyes had smaller anterior segments compared to Caucasian eyes. Regardless of race, anterior segment dimensions were smaller in older subjects. Age-related changes may affect the tolerability of long-term implants such as phakic intraocular lenses. PMID:22320411

    In a retrospective analysis of 87 cases of Caucasian childhood non-Hodgkin malignant lymphoma (NHML) from Lyon, France, all the case were diffuse lymphomas, but 47 were diagnosed as monomorphic small non-cleaved NHML, pathologically indistinguishable from Burkitt's lymphoma (BL). BL could then be the most frequent childhood lymphoma in France. This homogeneous series allows better definition of the characteristics of BL within NHML. Age distribution is similar to that of endemic BL, with a sex ratio of 3.7/1. Abdominal masses are initially present in 68% of the cases, whereas jaw is involved in only 4%. The disease is characterized by its overwhelming evolution in the absence of therapy. However, complete remission (CR) is usually obtained after the first chemtherapy regimen. Most relapses occur at 3-8 months. Death could be related to cerebrospinal fluid (CSF) involvement, local recurrence or secondary marrow involvement. Ninety per cent of the patients alive with no evidence of disease (NED) 8 months after CR can be considered as definitely cured. Our study on Caucasian children with NHML indicates that, from histological and clinical criteria, nearly half the cases are very similar to African BL. Even though EBV rarely associated with our cases, BL could be a worldwide lymphoma. PMID:7082553

    Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P < 0.0001). The change in vellus hair proportion (<40 μm) was significantly lower in the adenosine group than that in the placebo group (P = 0.0154). The change in hair density compared with baseline of the adenosine group was also significantly higher compared with that of the placebo group (P = 0.0470). No adverse effects due to treatment were noted during this study by dermatological evaluation. Adenosine is effective in increasing the proportion of thick hair in Caucasian men with AGA as well as in Japanese men and women. PMID:26508659

    The health impact of environmental toxins has gained increasing recognition over the years. Polycyclic aromatic hydrocarbons (PAHs) and environmental tobacco smoke (ETS) are known to affect nervous system development in children, but no studies have investigated how polymorphisms in PAH metabolic or detoxification genes affect child cognitive development following PAH exposure during pregnancy. In two parallel prospective cohort studies of nonsmoking African American and Dominican mothers and children in New York City and of Caucasian mothers and children in Krakow, Poland, we explored the effect of gene-PAH interaction on child mental development index (MDI), as measured by the Bayley Scales of Infant Development-Revised (BSID-II). Genes known to play important roles in the metabolic activation or detoxification of PAHs were selected. Genetic variations in these genes could influence susceptibility to adverse effects of PAHs in polluted air. We explored the effects of interactions between prenatal PAH exposure and 21 polymorphisms or haplotypes in these genes on MDI at 12, 24, and 36 months among 547 newborns and 806 mothers from three different ethnic groups: African Americans, Dominicans, and Caucasians. PAHs were measured by personal air monitoring of mothers during pregnancy. Significant interaction effects between haplotypes and PAHs were observed in mothers and their newborns in all three ethnic groups after Bonferroni correction for multiple comparisons. The strongest and most consistent effect observed was between PAH and haplotype ACCGGC of the CYP1B1 gene. PMID:19860743

    The study of the craniofacial relations and variations in man has long been used to differentiate various racial groups in physical anthropology. Morphologic features of different races and ethnic groups are not randomly distributed but appear in geographic clusters. Richardson wonders whether there is only one race, comprising ethnic groups separated by cultural, climatic, and geographic boundaries, causing subtle changes in facial morphology. Since the introduction of roentgenographic cephalometry in orthodontics, several methods of analysis have been developed for clinical diagnosis and treatment planning. Also, these methods have been used to establish the cephalometric norms of different ethnic groups: American Negro, Australian aborigine, American Mexican, Norwegian, Indian, Japanese, Swedish, and Iranian. Sassouni, Ricketts, and others have concluded that norms differ between Caucasians and other ethnic and racial groups. Ethnic differences in facial traits do exist. Awareness of the normal dentofacial pattern of each ethnic group will undoubtedly ensure better success of treatment to establish optimal facial harmony. These conclusions prompted the present investigation, which compares Greek and American-Caucasian dentofacial patterns of adolescents, and provides information on the facial characteristics of Greek adolescents. To date, no similar study has been made. PMID:2923103

    Non-syndromic oculocutaneous albinism (OCA) is a clinically and genetically heterogeneous autosomal recessive disorder with mutations identified in several genes: OCA1 (tyrosinase, TYR), OCA2 (OCA2), OCA3 (tyrosinase-related protein 1, TYRP1), and OCA4 (membrane-associated transporter protein, MATP). OCA3 was thought to be restricted to black populations, where it was clinically described as rufous or brown albinism, until the recent report of a homozygous TYRP1 mutation in Caucasian patients from a consanguineous Pakistani family. Here, we describe a German patient of Caucasian origin, with a light-yellow skin, yellow-gold hair with orange highlights, fair eyelashes, several pigmented naevi, and no tendency to tan, only to burn. Eye-colour is blue-green with substance defects of the iris. Molecular analysis did not reveal any mutation in the TYR and OCA2 genes. Two mutations were found in the TYRP1 gene: a missense mutation (c.1066G>A/p.Arg356Glu) that was inherited from the mother, and a de novo single-base deletion (c.106delT/p.Leu36X). This finding suggests that mutation screening should be extended to the TYRP1 gene in patients from all ethnic origins, at least in cases where no mutations have been identified in the other OCA genes.

    This phase 1 study evaluated the single-dose pharmacokinetics and safety of subcutaneous golimumab, a human anti-tumor necrosis factor-alpha monoclonal antibody, in healthy Japanese and Caucasian subjects. Eligible subjects were males, aged 20 to 45 years, weighing 50 to 90 kg with a body mass index of 19 to 30 kg/m(2). Japanese and Caucasian subjects were matched by body weight and dose group. Blood samples were collected through day 50 following a single subcutaneous injection of golimumab 50 or 100 mg. The pharmacokinetic parameters were determined using a noncompartmental method. All 51 subjects (24 Japanese, 27 Caucasian) were included in the safety analysis; 47 completed the study and were included in the pharmacokinetic analysis. The pharmacokinetics of golimumab were comparable in both race groups. Peak concentrations were observed approximately 4 to 6 days after administration. No significant differences in exposure or mean half-life (range, 11-13 days) were observed between Japanese and Caucasian subjects at the same dose level. Regardless of race, serum golimumab exposure increased with increasing dose. Mean apparent clearance ranged from 12 to 19 mL/kg/d. Mean apparent volume of distribution (224-262 mL/kg) remained constant with an increase in dose. No antibodies to golimumab were detected. Single subcutaneous injections of golimumab 50 mg or 100 mg were generally well tolerated in these healthy male Japanese and Caucasian subjects. PMID:20133508

    The effects of Asian and Caucasian facial morphology were examined by having Canadian children categorize pictures of facial expressions of basic emotions. The pictures were selected from the Japanese and Caucasian Facial Expressions of Emotion set developed by D. Matsumoto and P. Ekman (1989). Sixty children between the ages of 5 and 10 years were presented with short stories and an array of facial expressions, and were asked to point to the expression that best depicted the specific emotion experienced by the characters. The results indicated that expressions of fear and surprise were better categorized from Asian faces, whereas expressions of disgust were better categorized from Caucasian faces. These differences originated in some specific confusions between expressions. PMID:10971913

    Background Interventions using mobile health (mHealth) apps have been effective in promoting healthy lifestyle behavior change and hold promise in improving health outcomes to thereby reduce health disparities among diverse racial/ethnic populations, particularly Latino and Asian American subgroups (Filipinos and Koreans) at high risk for diabetes and cardiovascular disease. Latinos and Asian Americans are avid digital technology owners and users. However, limited datasets exist regarding digital technology ownership and use, especially among specific racial/ethnic subgroups. Such information is needed to inform development of culturally tailored mHealth tools for use with lifestyle interventions promoting healthy behaviors for these at-risk racial/ethnic populations. Objective The intent of the study was to examine (1) digital technology ownership and usage, and (2) factors predicting downloading health apps for Caucasian, Filipino, Korean, and Latino American subgroups. Methods A cross-sectional survey conducted in August 2013 through December 2013 recruited 904 participants (Caucasians n=172, Filipinos n=250, Koreans n=234, and Latinos n=248), age >18 years, from California community events, clinics, churches, and online. English, Spanish, and Korean surveys were administered via paper or online. Descriptive statistics characterized the sociodemographics and digital technology ownership/usage of the 904 participants. Differences among groups in categorical variables were examined using chi-square statistics. Logistic regression was used to determine factors predicting downloading health apps. Results Overall, mean age was 44 years (SD 16.1), with 64.3% (581/904) female. Only 44.7% (404/904) of all participants reported English as their primary language (Caucasian 98.3%, 169/172; Filipino 67.6%, 169/250; Korean 9.4%, 22/234, and Latino 17.7%, 44/248.

    Asians have a lower prevalence of hypertensive disorders of pregnancy than Caucasians. Since sympathetic overactivity and dysregulation of the renal-adrenal system (e.g. low aldosterone levels) have been found in preeclamptic women, we hypothesized that Asians have lower muscle sympathetic nerve activity (MSNA) and greater aldosterone concentrations during normal pregnancy than Caucasians. In a prospective study, blood pressure (BP), heart rate (HR), and MSNA were measured during supine and upright tilt (30 deg and 60 deg for 5 min each) in 9 Asians (32 ± 1 years (mean ± SEM)) and 12 Caucasians (29 ± 1 years) during pre-, early (≤8 weeks of gestation) and late (32-36 weeks) pregnancy, and post-partum (6-10 weeks after delivery). Supine MSNA increased with pregnancy in both groups (P < 0.001); it was significantly lower in Asians than Caucasians (14 ± 3 vs. 23 ± 3 bursts min(-1) and 16 ± 5 vs. 30 ± 3 bursts min(-1) in early and late pregnancy, respectively; P = 0.023). BP decreased during early pregnancy (P < 0.001), but was restored during late pregnancy. HR increased during pregnancy (P < 0.001) with no racial difference (P = 0.758). MSNA increased during tilting and it was markedly lower in Asians than Caucasians in late pregnancy (31 ± 6 vs. 49 ± 3 bursts min(-1) at 60 deg tilt; P = 0.003). Upright BP was lower in Asians, even in pre-pregnancy (P = 0.006), and this racial difference persisted during pregnancy. Direct renin and aldosterone increased during pregnancy (both P < 0.001); these hormones were greater in Asians (P = 0.086 and P = 0.014). Thus, Asians have less sympathetic activation but more upregulated renal-adrenal responses than Caucasians during pregnancy. These results may explain, at least in part, why Asian women are at low risk of hypertensive disorders in pregnancy. PMID:25545472

    The effect of exercise intensity on the on- and off-transient kinetics of oxygen uptake (VO2) was investigated in African American (AA) and Caucasian (C) women. African American (n=7) and Caucasian (n=6) women of similar age, body mass index and weight, performed an incremental test and bouts of square-wave exercise at moderate, heavy and very heavy intensities on a cycle ergometer. Gas exchange threshold (LTGE) was lower in AA (13.6±2.3mL·kg−1min−1) than C (18.6±5.6mL·kg−1min−1). The dynamic exercise and recovery VO2 responses were characterized by mathematical models. There were no significant differences in 1) peak oxygen uptake (VO2peak) between AA (28.5±5mL kg−1min−1) and C (31.1±6.6mL kg−1min−1) and 2) VO2 kinetics at any exercise intensity. At moderate exercise, the on- and off- VO2 kinetics was described by a mono-exponential function with similar time constants τ1,on (39.4±12.5s;38.8±15s) and τ1,off (52.7±10.1s;40.7±4.4s) for AA and C, respectively. At heavy and very heavy exercise, the VO2 kinetics was described by a double-exponential function. The parameter values for heavy and very heavy exercise in the AA group were respectively: τ1,on (47.0±10.8;44.3±10s), τ2,on (289±63;219±90s), τ1,off (45.9±6.2;50.7±10s), τ2,off (259±120;243±93s) while in the C group were respectively: τ1,on (41±12;43.2±15s); τ2,on(277±81;215±36s), τ1,off (40.2±3.4;42.3±7.2s), τ2,off (215±133;228±64s). The on- and off-transients were symmetrical with respect to model order and dependent on exercise intensity regardless of race. Despite similar VO2 kinetics, LTGE and gain of the VO2 on-kinetics at moderate intensity were lower in AA than C. However, generalization to the African American and Caucasian populations is constrained by the small subject numbers. PMID:21717119

    Cystic fibrosis (CF) is one of the more common lethal autosomal recessive disorders in Caucasian populations. Numerous hypotheses including genetic drift, founder effect, sex ratio, segregation distortions and various forms of heterozygote advantage have been proposed to explain the relatively high frequency of CF alleles. The observation of high linkage disequilibrium between markers at the 5{prime} end of CFTR and mutations that cause CF raised the possibility of epistatic selection. CF-linked marker allele frequencies were determined in 417 elderly individuals from a stable Czech population that survived high levels of infant and childhood mortality in the pre-antibiotic era. These data were compared with allele frequencies of 646 contemporary newborns and 345 young adults drawn from the same population who had significantly lower mortality rates in the antibiotic era. Allele frequencies of markers CS7/Hhal and KM19/Pstl from the D7S23 locus are significantly different (p<0.05) between elderly female and male subjects in this population. Furthermore, there is a significant difference in the allele frequencies of marker CS7/Hhal when newborn females and elderly women are compared (p<0.05). Taken together, these data suggest that the allele status at the CS7 region influenced female survival in the period of high infant and childhood mortality in the pre-antibiotic era. Under this selective pressure, CFTR mutations that occurred on the {open_quotes}favorable{close_quotes} background would marginally increase in frequency in each successive generation and more ancient mutations residing on this background would become the most frequent in the general population.

    Context: The African-American skeleton is resistant to PTH; whether it is also resistant to PTHrP and the hormonal milieu of lactation is unknown. Objectives: The objective of the study was to assess bone turnover markers in African-Americans during lactation vs Caucasians. Design and Participants: A prospective cohort study with repeated measures of markers of bone turnover in 60 African-American women (3 groups of 20: lactating, bottle feeding, and healthy controls), compared with historic Caucasian women. Setting: The study was conducted at a university medical center. Outcome Measures: Biochemical markers of bone turnover and calcium metabolism were measured. Results: 25-Hydroxyvitamin D (25-OHD) and PTH were similar among all 3 African-American groups, but 25-OHD was 30%–50% lower and PTH 2-fold higher compared with Caucasians (P < .001, P < .002), with similar 1,25 dihydroxyvitamin D [1,25(OH)2D] values. Formation markers [amino-terminal telopeptide of procollagen-1 (P1NP) and bone-specific alkaline phosphatase (BSAP)] increased significantly (2- to 3-fold) in lactating and bottle-feeding African-American women (P1NP, P < .001; BSAP, P < .001), as did resorption [carboxy-terminal telopeptide of collagen-1 (CTX) and serum amino-terminal telopeptide of collagen 1 (NTX), both P < .001]. P1NP and BSAP were comparable in African-American and Caucasian controls, but CTX and NTX were lower in African-American vs Caucasian controls. African-American lactating mothers displayed quantitatively similar increases in markers of bone formation but slightly lower increases in markers of resorption vs Caucasians (P = .036). Conclusions: Despite reported resistance to PTH, lactating African-American women have a significant increase in markers of bone resorption and formation in response the hormonal milieu of lactation. This response is similar to that reported in Caucasian women despite racial differences in 25-OHD and PTH. Whether this is associated with similar bone

    Allele frequencies for six PCR-based loci and three protein-based (i.e., enzyme systems) loci were determined in a Caucasian sample population from New Jersey. The loci are LDLR, GYPA, HBGG, D7S8, Gc, HLA-DQA1, PGM1, ESD, and EAP. All loci meet Hardy-Weinberg expectations. In addition, there is little evidence for association of alleles among the nine loci. The allelic frequency data generally are similar to another Caucasian population database. PMID:9068180

    Background: Female pattern hair loss (FPHL) is the most common cause of alopecia in women, characterized by diffuse nonscarring hair loss in frontal, central, and parietal areas of the scalp. Pathophysiology of FPHL is still not well known, and it is probably a multifactorial genetic trait. FPHL is also observed in women without increased androgen levels, which raises the likelihood of androgen-independent mechanisms and explains the lack of response to antiandrogen treatments in some patients. Vitamin D is a factor that has recently been considered in dealing with these patients. The purpose of this study was to evaluate the serum levels of Vitamin D in patients with FPHL and compare it with healthy controls. Methods: In this case-control study, 45 women with FPHL were evaluated as well as the same number of healthy women matched for age, hours spent under sunlight per day, and body mass index. Serum 25(OH) D3 level was measured using ELISA. Results: 60% of FPHL patients were in 15–30 years old age group with the mean standard deviation (SD) age of 29.11 (7.30) years. In the majority of patients (66.7%), severity of hair loss was Ludwig I. Mean (SD) serum Vitamin D3 level in patient and control group was 13.45 (8.40) and 17.16 (8.96), respectively. T-test showed a significant difference between the two groups in terms of Vitamin D3 serum levels (P = 0.04). Conclusions: This study indicated the correlation between the incidence of FPHL and decreased serum levels of Vitamin D3. It is recommended to evaluate serum Vitamin D3 levels as well as other hormone assays in these patients. PMID:27625563

    Equol production, isoflavone excretion, and the salivary estradiol profile among 36 females, native Irish Caucasian volunteers following ingestion of 200mL soymilk is reported. The soymilk contained daidzein (73+/-6.7mg) and genistein (86+/-10.2mg). Volunteers provided personal and family medical history. Dietary analysis revealed that all volunteers regularly consumed soy-based or soy-supplemented food products. The mean age, mean age at menarche, and body mass index of volunteers were 46.6+/-12.3 years, 13.1 years and 26.1, respectively. The average number of children per volunteer was 2.13. Twelve (34%) of the volunteers were found to be first-degree relatives of breast cancer patients. Following consumption of the soymilk, equol was detected in the urine of 18 (51%) of the volunteers. Mean urinary daidzein and genistein concentrations during the hours following soymilk ingestion were 13.5 and 16.7microg/mg creatinine, respectively, however, some volunteers excreted little (less than 4.0microg/mg) or no isoflavone. Salivary estradiol in most (24) volunteers had decreased from 51.5+/-28.67pmol/L pre-ingestion to 29.75+/-16.13pmol/L 5h after drinking the soymilk. However, the salivary estradiol in 12 subjects (34%) increased from 33.76+/-13.4pmol/L to 137.4+/-65.64pmol/L over the same period. Individuals whose salivary estradiol increased had significantly less children (1.58 (P<0.05)), were more likely to (a) return urine samples with low isoflavone content (50.3% compared to 25%), (b) to be equol producers (67% compared to 41.7%), and (c) to be first-degree relatives of breast cancer patients (41.7% compared to 25%). Volunteers who reported a first-degree link to breast cancer were more likely to have a higher body mass index (29.0 compared to 26.1 (P<0.05)), to be equol producers (75% compared to 51%), and to excrete isoflavones in low quantities only (60% compared to 50%). First-degree relatives also had fewer children (1.75 (P<0.05)). The results indicate a

  20. Of Caucasians, Asians, and Giraffes: The Influence of Categorization and Target Valence on Social Projection.

    Past research has indicated that social projection is moderated by categorization, with more projection onto ingroups than onto outgroups. However, a few studies have reported elevated levels of projection even onto outgroups. In line with recent evidence, we hypothesized that positive target valence is the key feature of conditions that elicit projection onto outgroups. The present research extends previous findings by testing whether the effect of valence occurs independent of categorization, with increased levels of projection onto positive ingroup and non-ingroup targets alike. We designed two experiments in which target valence was manipulated by means of evaluative conditioning. Category membership was varied by using faces of Caucasians, Asians, and giraffes. The results supported our valence hypothesis. Counter-intuitively, we also found higher levels of projection onto giraffes than onto humans. These findings suggest that current cognition-based models of projection are not sufficient to account for the whole range of projection phenomena. PMID:26160332

    Summary Introduction: Several techniques can be performed to improve nasal tip definition such as cartilage resection, tip grafts, or sutures. Objctive: To evaluate the outcome of lateral intercrural suture at the lower lateral cartilage by endonasal rhinoplasty with a basic technique without delivery in decreasing the angle of domal divergence and improving the nasal tip definition. Method: This prospective study was performed in 64 patients in which a suture was made on the board head of the lower lateral cartilage in the joint between the dome and lateral crus, using polydioxanone (PDS) with sharp, curved needle. Results: In all of the cases, better definition of the nasal tip was achieved by intercrural suturing for at least 6 months postoperatively. Conclusion: Lateral intercrural suture of the lower lateral cartilage provides improved nasal tip definition and can be performed by endonasal rhinoplasty without delivery in the Caucasian nose.

    The growth of children whose parents originated from the Indian subcontinent (Asians) and of indigenous, white children in Rochdale (Caucasians) has been related to dietary intake which was estimated by 3-day weighed intakes during a longitudinal study at 3, 6, 9, 12 and 24 months of age. The use of human milk vis-à-vis infant milk formulas, the age of introduction of solid food and the effect of other environmental factors were also evaluated. Multiple regression analysis revealed the effects of diet per se on growth to be fairly minimal; a maximum of 28 per cent of the variation in growth could be explained by diet and the few individual nutrients significantly correlated with a growth index were not consistent.

    The alar-spanning suture is one of the easiest techniques for correcting the width of the alar complex that reduces the bulbous tip of African-Caucasian patients. This conservative technique does not weaken the lateral crura and yields long- term predictable results. Rhinoplastic surgeons should keep in mind this useful and reliable tool in their options for refinement of these challenging wide tips and not create so dramatic a change that the appearance is not consonant with the patient's ethnic heritage. Despite cosmetic surgeons usually performing it through an external columellar incision approach, it is possible, in many cases, to do it in a closed access, and thus avoid the risk of hyperpigmentation or hypertrophic scarring.

    A 60-year-old lady of Chinese origin presented with a right medial canthal mass. The lesion had been present for many years but progressively increased in size a few months prior to the consultation. Clinical examination revealed a medial canthal mass measuring 1.8 cm in diameter. It was firm with an irregular crusting surface. It was not attached to underlying deep lamella, and there were overlying telangiectatic vessels with contact bleeding. Excisional biopsy of the lesion confirmed a diagnosis of eccrine porocarcinoma. Eccrine porocarcinoma rarely occurs in the eyelid, and this is the first reported case of its occurrence in non-Caucasian patient. Given the significant risk of recurrence and metastasis, long-term surveillance is warranted. Although being rare, ophthalmologists should be vigilant of this potentially life-threatening lesion in the management of eyelid tumors. PMID:24841732

    Type 2 diabetes mellitus (T2DM) is one of the leading causes of morbidity and mortality. While all ethnic groups are affected, the prevalence of T2DM in South Asians, both in their home countries and abroad, is extremely high and is continuing to rise rapidly. Innate biological susceptibilities coupled with rapid changes in physical activity, diet, and other lifestyle behaviors are contributing factors propelling the increased burden of disease in this population. The large scope of this problem calls for investigations into the cause of increased susceptibility and preventative efforts at both the individual and population level that are aggressive, culturally sensitive, and start early. In this review, we outline the biological and environmental factors that place South Asians at elevated risk for T2DM, compared with Caucasian and other ethnic groups. PMID:23317344

    Data on the complex genetic analysis of three sympatric species of Caucasian wood mice, Apodemus ponticus, A. fulvipectus, and A. uralensis are presented. A high degree of genetic differentiation at the isozymic, karyological and molecular (nuclear DNA) levels was revealed. The genetic distances between each pair of species varied significantly within a wide range depending on the analyzed level of the organization of genetic material. Mean values of genetic divergence from one species to another were also variable. These findings indicated that evolution of chromosomes was slower than that of isozymes, and the degree of species divergence was similar on cytogenetic and molecular levels. They also suggested that the rates of species evolution could vary in different phyletic lineages and on different levels of organization. Some phyletic lineages of Apodemus could be distinguished by different directions of evolution. PMID:9589852

    Within the oceanic area of Tethys, with a typical oceanic crust, in geological past relatively small continental or subcontinental plates (terranes) were situated. The Greater Caucasian, Black Sea - Central Transcaucasian, Baiburt - Sevanian and Iran - Afghanian accretionary terranes, which in geological past represented island arcs or microcontinents, are identified in the Caucasian segment of the Alpine-Mediterranean belt. They are separated by ophiolite sutures (relics of small or large oceanic basins) of different age. During the Late Precambrian, Paleozoic and Early Mesozoic these terranes underwent horizontal displacement in different directions and ultimately they joined the Eurasian continent. New LA-ICP-MS U-Pb zircon dating along with available geologic, petrologic and geochemical investigations, allow to trace with confidence the main stages of regional metamorphism, granite formation and, consequently, pre-Alpine continental crust making within the Caucasus. At the pre-Grenville stage (1200 Ma and more) between the Baltica and Gondvana ancient continents, on the oceanic crust of Prototethys accumulation mainly of terrigenous sediments and of basic volcanites took place. At the Grenville stage (1000-800 Ma) subcontinental or primitive continental crust (gneiss-migmatite complex and synmetamorphic grenitoids of sodium series) were formed in suprasubduction conditions by both sides of Proto-Paleotethys and along the northern peripheries of comparatively small oceanic basins of the Arkhiz and Southern Slope of the Greater Caucasus. At the Baikalian stage (650-550 Ma) plagiogneissic complex has been cut by Precambrian gabbroids and intruded by large bodies of quartz-diorites. The next, Late Baikalian stage (540-500 Ma) is determined by the intrusion of Cambrian basites and Late Baikalian granitoids and by manifestation of intensive suprasubduction regional metamorphism. Late Baikalian tectogenesis is accompanied by contraction of the small oceanic basin of

    Histidine decarboxylase gene (HDC) encodes histidine decarboxylase which is the crucial enzyme for the biosynthesis of histidine. Studies have shown that histamine is likely to be involved in the regulation of reproduction system. To find the possible correlation between HDC gene and AANM (age at natural menopause), we selected 265 postmenopausal women from 131 nuclear families and performed a transmission disequilibrium test. Significant within-family associations with AANM for SNP rs854163 and SNP rs854158 of HDC gene were observed (P values=0.0018 and 0.0197, respectively). After 1000 permutations, SNP rs854163 still remained significant within-family association with AANM. Consistently, we also detected a significant within-family association between haplotype block 2 (defined by SNP rs854163 and rs860526) and AANM in the haplotype analyses (P value=0.0397). Our results suggest that the HDC gene polymorphisms are significantly associated with AANM in Caucasian women. PMID:16919600

    The Caucasus Mountain System is a part of the Cenozoic Alpine-Himalayan-Indonesian Convergence Zone (AHICZ) which lasted throughout Eurasia from Western Mediterranean to Western Pacific. This belt has been formed after closure of the Mesozoic Tethys and is marked by mountains building processes, appearance of riftogenic structures, numerous late Cenozoic basaltic plateaus, and chain of often within-continental andesite-latite volcanic arcs, which trace suture zones of the continental plates collision. Caucasus Mountains are located in eastern part of the proper Alpine Zone in zone of Arabian-Eurasian syntaxis and appeared as a result of submeridional pressure which generated by oncoming moving of these plates. The Great Caucasus is represent the south border of the Eurasian plate, uplifted along the Main Caucasian Fault (Thrust). The latter is a part of super-regional deep-seated fault ranged from the Kopetdag through Caspian Sea, Caucasus and Crimea; very likely, that its further continuation is Tornquist-Teisseyre Zone. This superfault separates areas of Alpine convergence from Eurasian plate sensu stricto. The Caucasus occurred between Black and Caspian seas with passive margins and oceanic crust, covered by sediments of 10-15 km thick. Depressions of the seas form large "downfall", or caldrons which cut off pre-Pliocene structures of Caucasus and Kopetdag. These seas are, probably, small remnants of the Tethys which gradually shallowing in the Miocene (Zonenshain, Le Pichon, 1986). New essential deepening of the Black Sea and South-Caspian deep began in the Pliocene- Quaternary; it occurred simultaneously with uprising of Crimea and Caucasus, which were not marked in relief before (Grachev, 2000). Large positive isostatic anomaly beneath the Trans-Caucasian Transverse Uplift (TCTU) of the Great Caucasus and Lesser Caucasus, which stretch out to Arabian plate, occurred between "subsides" Black and especially Caspian seas with neutral to negative isostatic

    Purpose To compare the keratometric and pachymetric parameters of healthy eyes with those affected by steep cornea and keratoconus (KC) using Scheimpflug camera. Setting Briz-L Eye Clinic, Baku, Azerbaijan. Design A cross-sectional study. Methods In this study, 49 KC (Amsler–Krumeich stage 1) eyes and 36 healthy eyes were enrolled. A complete ophthalmic evaluation and a Scheimpflug camera scan were performed in every eye included in the study. Tomographic parameters such as parameters from the front and back cornea, maximum keratometry reading (Kmax), corneal volume (CV), anterior chamber volume (ChV), anterior chamber depth (ACD), anterior chamber angle (AC angle), keratometric power deviation (KPD), maximum front elevation (Max FE), and maximum back elevation (Max BE), as well as pachymetric progression indices (PPI), Ambrosio relational thickness (ART), index of surface variance (ISV), index of vertical asymmetry (IVA), center keratoconus index (CKI), index of height asymmetry (IHA), index of height decentration (IHD), and radius minimum (RM) were collected and statistically compared between the two groups. Results PPI, ART, ISV, IVA, CKI, IHA, IHD, and RM parameter values were significantly different (P<0.05) between the KC and healthy eyes. There were no significant differences in K mean and Q values of the frontal corneal parameters, as well as in Kmax, AC angle, RM, back, and front astigmatism, between stage 1 keratoconic and normal Caucasian eyes with steep cornea. All other parameters such as K mean and Q values of the back corneal parameters, Max FE, Max BE, ACD, ChV, and CV showed significant differences between the groups (P<0.05 for all). Conclusion Scheimpflug imaging is able to detect corneal morphological differences between stage 1 KC eyes and healthy eyes with steep cornea, in Caucasians. PMID:27099469

    Interindividual differences in metabolism of the soy isoflavone, daidzein, to equol and O-desmethylangolensin (ODMA) by human gut bacteria, have been associated with altered risk of cancer and other chronic diseases, according to some studies. Differences have been reported in the prevalence of the equol-producer phenotype among populations, with a higher prevalence in soy-consuming Asian populations than in Western populations. To date, prevalence of the daidzein-metabolizing phenotypes in Asians, compared with Caucasians, has not been evaluated in the context of a standardized phenotyping method. We assessed the prevalence of equol- and ODMA-producer phenotypes in 91 Korean American (KA) women and girls living in the Seattle, Washington area and compared this with previous similarly collected prevalence data in Caucasian American (CA) women and girls (n = 222). We also compared the dietary habits of the 2 groups. Isoflavonoid concentrations in first-void morning urines, collected after a 3-d soy challenge, were used to establish equol-, and ODMA-producer phenotypes (>44 microg/L). The prevalence of the equol-producer phenotype was higher (51 vs. 36%; P = 0.015) and the ODMA-producer phenotype was lower (84 vs. 92%, P = 0.03) in KA than in CA women and girls. KAs consumed approximately 3 times more soy foods than the CAs, but no significant associations were found between the consumption of soy foods and equol-producer phenotype. Our findings support the reports that, compared with Western populations, Asian populations have a higher equol-producer prevalence. The additional observation that the prevalence of the ODMA-producer phenotype is lower in KAs suggests that daidzein-metabolizing patterns in general may differ between KAs and CAs. PMID:16614428

    Objective: Typically regarded as an adolescent condition, acne among adult females is also prevalent. Limited data are available on the clinical characteristics and burden of adult female acne. The study objective was to describe clinical characteristics and psychosocial impact of acne in adult women. Design: Cross-sectional, web-based survey. Setting: Data were collected from a diverse sample of United States females. Participants: Women ages 25 to 45 years with facial acne (≥25 visible lesions). Measurements: Outcomes included sociodemographic and clinical characteristics, perceptions, coping behaviors, psychosocial impact of acne (health-related quality of life using acne-specific Quality of Life questionnaire and psychological status using Patient Health Questionnaire), and work/productivity. Results: A total of 208 women completed the survey (mean age 35±6 years), comprising White/Caucasian (51.4%), Black/African American (24.5%), Hispanic/Latino (11.1%), Asian (7.7%), and Other (5.3%). Facial acne presented most prominently on cheeks, chin, and forehead and was characterized by erythema, postinflammatory hyperpigmentation, and scarring. Average age of adult onset was 25±6 years, and one-third (33.7%) were diagnosed with acne as an adult. The majority (80.3%) had 25 to 49 visible facial lesions. Acne was perceived as troublesome and impacted self-confidence. Makeup was frequently used to conceal acne. Facial acne negatively affected health-related quality of life, was associated with mild/moderate symptoms of depression and/or anxiety, and impacted ability to concentrate on work or school. Conclusion: Results highlight the multifaceted impact of acne and provide evidence that adult female acne is under-recognized and burdensome. PMID:24578779

    This study examined racial differences in eating-disorder psychopathology, eating/weight-related histories, and biopsychosocial correlates in women (n = 53 Caucasian and n = 56 African American) with comorbid binge eating disorder (BED) and obesity seeking treatment in primary care settings. Caucasians reported significantly earlier onset of binge eating, dieting, and overweight, and greater number of times dieting than African American. The rate of metabolic syndrome did not differ by race. Caucasians had significantly elevated triglycerides whereas African Americans showed poorer glycaemic control (higher glycated haemoglobin A1c [HbA1c]), and significantly higher diastolic blood pressure. There were no significant racial differences in features of eating disorders, depressive symptoms, or mental and physical health functioning. The clinical presentation of eating-disorder psychopathology and associated psychosocial functioning differed little by race among obese women with BED seeking treatment in primary care settings. Clinicians should assess for and institute appropriate interventions for comorbid BED and obesity in both African American and Caucasian patients. PMID:26640009

    2014-01-01

    A central claim of cultural neuroscience is that the culture to which an individual belongs plays a key role in shaping basic cognitive processes and behaviours, including eye movement behaviour. We previously reported a robust difference in saccade behaviour between Chinese and Caucasian participants; Chinese participants are much more likely to execute low latency express saccades, in circumstances in which these are normally discouraged. To assess the extent to which this is the product of culture we compared a group of 70 Chinese overseas students (whose primary cultural exposure was that of mainland China), a group of 45 participants whose parents were Chinese but who themselves were brought up in the UK (whose primary cultural exposure was western European) and a group of 70 Caucasian participants. Results from the Schwartz Value Survey confirmed that the UK-Chinese group were culturally similar to the Caucasian group. However, their patterns of saccade latency were identical to the mainland Chinese group, and different to the Caucasian group. We conclude that at least for the relatively simple reflexive saccade behaviour we have investigated, culture cannot explain the observed differences in behaviour. PMID:24709988

In this report, we present the first case of a Caucasian patient with the p.Val122Ile mutated TTR-related cardiac amyloidosis treated with heart transplantation due to this gene mutation frequent in Afro-Americans with a prevalent isolated heart involvement. The choice of isolated heart transplantation instead of combined heart and liver transplantations was based on (1) severe and progressive cardiac disease, (2) evidence of a gene mutation generally associated with isolated cardiac disease and (3) absence of relevant extra-cardiac involvement (with the possible exception of mild peripheral neuropathy). In any case, the very short post-transplant observation period of 10 months does not allow any conclusions on the long-term course of the presented strategy. Finally, it is the first European Caucasian family with the p.Val122Ile TTR mutation that has been described. Till now, very few Caucasian cases of p.Val122Ile mutated TTR-related cardiac amyloidosis have been reported. The patient and some members of his family also had mild peripheral neuropathy suggesting a regional phenotypic heterogeneity of European Caucasian TTR p.Val122Ile. PMID:22449240

    Substantial data indicate that oxidative stress is involved in the development of diabetic retinopathy. Two candidate genes that affect the oxidative stress are manganese mitochondrial superoxide dismutase (Mn-SOD) and endothelial nitric oxide synthase (eNOS). The aim of the present study was to examine the role of the V16A polymorphism of the Mn-SOD gene and the 4a/b polymorphism of the eNOS gene in the development of diabetic retinopathy in Caucasians with type 2 diabetes. In this cross sectional case-control study 426 unrelated Slovene subjects (Caucasians) with type 2 diabetes mellitus were enrolled: 283 patients with diabetic retinopathy and the control group of 143 subjects with type 2 diabetes of duration of more than 10 years who had no clinical signs of diabetic retinopathy. A significantly higher frequency of the VV genotype of the V16A polymorphism of the Mn-SOD was found in patients with diabetic retinopathy compared to those without diabetic retinopathy (OR=2.1, 95% CI = 1.2–3.4; p = 0.006), whereas the 4a/b polymorphism of the eNOS gene failed to yield an association with diabetic retinopathy. We may conclude that the VV genotype of the V16A polymorphism of the Mn-SOD gene was associated with diabetic retinopathy in Caucasians with type 2 diabetes, therefore it might be used as a genetic marker of diabetic retinopathy in Caucasians.

    A substantial research literature implicates potential racial/ethnic bias in the diagnosis of schizophrenia and in clinical ratings of psychosis. There is no similar information regarding bias effects on ratings of everyday functioning. Our aims were to determine if Caucasian raters vary in their ratings of the everyday functioning of schizophrenia patients of different ethnicities, to find out which factors determine accurate self-report of everyday functioning in different ethnic groups, and to know if depression has similar effects on the way people of different ethnicities self-report their current functionality. We analyzed data on 295 patients with schizophrenia who provided their self-report of their everyday functioning and also had a Caucasian clinician rating their functionality. Three racial/ethnic groups (African American (AA), Hispanic and Caucasian) were studied and analyzed on the basis of neurocognition, functional capacity, depression and real-world functional outcomes. No differences based on racial/ethnic status in clinician assessments of patients' functionality were found. Differences between racial groups were found in personal and maternal levels of education. Severity of depression was significantly correlated with accuracy of self-assessment of functioning in Caucasians, but not in AAs. Higher scores on neurocognition and functional capacity scales correlated with reduced overestimation of functioning in AAs, but not in Hispanics. This data might indicate that measurement of everyday functionality is less subject to rater bias than measurement of symptoms of schizophrenia. PMID:26160197

  8. Use of oral anticoagulants in African-American and Caucasian patients with atrial fibrillation: is there a treatment disparity?

    Atrial fibrillation (AF) is a very common cardiac arrhythmia, and its prevalence is increasing along with aging in the developed world. This review discusses racial differences in the epidemiology and treatment of AF between African-American and Caucasian patients. Additionally, the effect of race on warfarin and novel oral anticoagulant use is discussed, as well as the role that physicians and patients play in achieving optimal treatment outcomes. Despite having a lower prevalence of AF compared with Caucasians, African-Americans suffer disproportionately from stroke and its sequelae. The possible reasons for this paradox include poorer access to health care, lower health literacy, and a higher prevalence of other stroke-risk factors among African-Americans. Consequently, it is important for providers to evaluate the effects of race, health literacy, access to health care, and cultural barriers on the use of anticoagulation in the management of AF. Warfarin-dose requirements vary across racial groups, with African-American patients requiring a higher dose than Caucasians to maintain a therapeutic international normalized ratio; the novel oral anticoagulants (dabigatran, rivaroxaban, and apixaban) seem to differ in this regard, although data are currently limited. Minority racial groups are not proportionally represented in either real-world studies or clinical trials, but as more information becomes available and other social issues are addressed, the treatment disparities between African-American and Caucasian patients should decrease.

    Background: The epidemiological evaluation of androgenetic alopecia (AGA) is based mainly on direct observation and questionnaires. The international epidemiology and environmental risk factors of AGA in young Caucasian men remain unknown. Aim: To use photographs and data from the Internet to evaluate severe AGA and generate greater understanding of the international epidemiology of the disorder in young Caucasian men. Materials and Methods: A population-based cross-sectional study design was used. The sample included 26,340 Caucasian men aged 30 to 40 years who had uploaded profiles to two dating websites. Their photographs were evaluated for AGA and graded as follows: severe AGA (Norwood type VI-VII), non-severe AGA, and unknown. Epidemiological data were collected from the sites. Logistic regression was used to analyze the effect of risk factors on the prevalence of severe AGA. Results The overall success rate for identifying severe AGA by indirect evaluation of Internet photographs was 94%. The prevalence of severe AGA was 15.33% overall and varied significantly by geographical region. The risk of having severe AGA was increased by 1.092 for every year of age between 30 and 40 years. Severe AGA was more prevalent in subjects with higher body mass index. Conclusions: Photographs from the Internet can be used to evaluate severe AGA in epidemiological studies. The prevalence of severe AGA in young Caucasian men increases with age and varies by geographical region. Body mass index is an environmental risk factor for severe AGA. PMID:26288425

    The relationship between partner violence and physical health symptoms is well-established. Although some researchers have theorized that the physical health effects of partner violence may be worse for ethnic minority women, there is little research addressing this topic. The current study examined whether African American women demonstrate a differential association in this relationship than Caucasian women. This study included 323 women (232 African American, 91 Caucasian) who participated in a larger investigation of the psychological and psychophysiological correlates of recent partner violence among women seeking help for the abuse. Race was examined as a moderator of the relationship between partner violence frequency and physical health symptoms. Although mean levels of partner violence frequency and physical health symptoms did not significantly differ between African American and Caucasian women, linear regression analyses demonstrated a significant positive relationship between partner violence frequency and physical health symptoms for African American women; whereas there was no association observed between these variables for Caucasian women. Post hoc analyses revealed that posttraumatic stress disorder symptoms partially mediated the association between partner violence frequency and physical health symptoms for the African American women. The current findings underscore the importance of considering race when studying the effect of partner violence on women’s health. PMID:23616911

    Inflammatory bowel disease is rare in the Chinese population, which may result in limited support, misinformation, and unalleviated fears and adversely affect quality of life (QOL). This study compared the inflammatory bowel disease (IBD)-related knowledge, QOL, and use of complementary and alternative medicines and therapies (CAMT) in two contrasting IBD populations. Chinese and Caucasian IBD patients completed a questionnaire on IBD knowledge and CAMT usage. QOL was evaluated using the validated Inflammatory Bowel Disease Questionnaire. One hundred sixty-two IBD patients were recruited, 81 Chinese and 81 Caucasian. The IBD knowledge score was higher in Caucasian than in Chinese IBD patients (median difference, 6.5; P = 0.001) and was independent of education and occupation. Twenty-one-percent of Chinese subjects incorrectly identified their IBD type (0% in the Caucasian group; P < 0.001). QOL was higher in the Chinese than the Caucasian group, but not significantly different after adjusting for disease activity. QOL was unassociated with IBD knowledge. The overall use of CAMT was similar in both groups (33% of Chinese and 37% of Caucasian patients) and similar for Crohn's disease and ulcerative colitis. IBD-related knowledge was inferior in Chinese compared to Caucasian IBD patients. Health-related QOL is unlikely to be greatly influenced by disease-related knowledge or education. A high proportion of Chinese and Caucasian IBD patients uses CAMT. PMID:15573925

    Background Disease prevalence and response to medical therapy may differ among patients of diverse ethnicities. Poor outcomes with in vitro fertilization (IVF) treatment have been previously shown in Indian women compared to Caucasian women, and some evidence suggests that poor embryo quality may be a cause for the discrepancy. In our center, only patients with the highest quality cleavage stage embryos are considered eligible for extending embryo culture to the blastocyst stage. We compared live birth rates (LBR) between Indian and Caucasian women after blastocyst transfer to investigate whether differences in IVF outcomes between these ethnicities would persist in patients who transferred similar quality embryos. Methodology/Principal Findings In this retrospective cohort analysis, we compared IVF outcome between 145 Caucasians and 80 Indians who had a blastocyst transfer between January 1, 2005 and June 31, 2007 in our university center. Indians were younger than Caucasians by 2.7 years (34.03 vs. 36.71, P = 0.03), were more likely to have an agonist down regulation protocol (68% vs. 43%, P<0.01), and were more likely to have polycystic ovarian syndrome (PCOS), although not significant, (24% vs. 14%, P = 0.06). Sixty eight percent of Indian patients had the highest quality embryos (4AB blastocyst or better) transferred compared to 71% of the Caucasians (P = 0.2). LBR was significantly lower in the Indians compared to the Caucasians (24% vs. 41%, P<0.01) with an odds ratio of 0.63, (95%CI 0.46–0.86). Controlling for age, stimulation protocol and PCOS showed persistently lower LBR with an adjusted odds ratio of 0.56, (95%CI 0.40–0.79) in the multivariate analysis. Conclusions/Significance Despite younger age and similar embryo quality, Indians had a significantly lower LBR than Caucasians. In this preliminary study, poor prognosis after IVF for Indian ethnicity persisted despite limiting analysis to patients with high quality embryos transferred

    Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI and n = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13, p = .004) and well-being (r = -.09, p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors. PMID:26850943

    Left ventricular hypertrophy (LVH) is predictive of cardiovascular disease. The vasodilator, natriuretic and diuretic actions of atrial natriuretic peptide (ANP) support a role in the pathophysiology of hypertension. Measuring the redundant precursor fragment mid-regional portion of pro-atrial natriuretic peptide (MRproANP) overcomes the technical difficulties of quantifying the bioactive ANP. This study sought to investigate the diagnostic and prognostic utility of MRproANP in a hypertensive Caucasian patient population. A total of 194 hypertensive patients (39 patients with LVH, 69±7.82 years of age, 74% female vs 155 patients without LVH, 68±6.51 years of age, 71% female) were derived from a screening study. Plasma MRproANP concentrations were quantified using immunoluminometric assays. Hypertensive patients with LVH had higher MRproANP concentrations than those without LVH (103.04 (50.58) vs 84.11 pmol l(-1) (44.82); P=0.014). Independent predictors of left ventricular mass index were LogMRproANP (P=0.022), male gender (P<0.001), body mass index (P=0.001) and history of angina or myocardial infarction (P=0.009). The receiver operating curve for MRproANP for the detection of LVH was limited, yielding an area under the curve of only 0.628 (confidence interval 0.523-0.733; P=0.014). Therefore, the role of MRproANP may not lie in the diagnosis of LVH but in monitoring the response to therapy. A nonsignificant trend towards greater mortality in patients with above-median MRproANP levels compared with below-median levels (P=0.167) was observed. Larger studies are required to assess its prognostic utility further. PMID:22113442

    Vascular calcifications are frequent in chronic renal disease and are associated to significant cardiovascular morbidity and mortality. The long term predictive value of coronary artery calcifications detected by multi-layer spiral computed tomography for major cardiovascular events was evaluated in non-diabetic Caucasian patients on maintenance hemodialysis free of clinical cardiovascular disease. Two-hundred and five patients on maintenance hemodialysis were enrolled into this observational, prospective cohort study. Patients underwent a single cardiac multi-layer spiral computed tomography. Calcium load was quantified and patients grouped according to the Agatston score: group 1 (Agatston score: 0), group 2 (Agatston score 1-400), group 3 (Agatston score 401-1000) and group 4 (Agatston score >1000). Follow-up was longer than seven years. Primary endpoint was death from a major cardiovascular event. Actuarial survival was calculated separately in the four groups with Kaplan-Meier method. Patients who died from causes other than cardiovascular disease and transplanted patients were censored. The “log rank” test was employed to compare survival curves. One-hundred two patients (49.7%) died for a major cardiovascular event during the follow-up period. Seven-year actuarial survival was more than 90% for groups 1 and 2, but failed to about 50% for group 3 and to <10% for group 4. Hence, Agatston score >400 predicts a significantly higher cardiovascular mortality compared with Agatston score <400 (p<0.0001); furthermore, serum Parathyroid hormone levels > 300 pg/l were associated to a lower survival (p < 0.05). Extended coronary artery calcifications detected by cardiac multi-layer spiral computed tomography, strongly predicted long term cardiovascular mortality in non-diabetic Caucasian patients on maintenance hemodialysis. Moreover, it was not related to conventional indices of atherosclerosis, but to other non-traditional risk factors, as serum Parathyroid

    Three distinct mitochondrial maternal lineages (haplotype Groups A, B, and C) have been found in the domestic sheep. Group B has been observed primarily in European domestic sheep. The European mouflon carries this haplotype group. This could suggest that European mouflon was independently domesticated in Europe, although archaeological evidence supports sheep domestication in the central part of the Fertile Crescent. To investigate this question, we sequenced a highly variable segment of mitochondrial DNA (mtDNA) in 406 unrelated animals from 48 breeds or local varieties. They originated from a wide area spanning northern Europe and the Balkans to the Altay Mountains in south Siberia. The sample included a representative cross-section of sheep breeds from areas close to the postulated Near Eastern domestication center and breeds from more distant northern areas. Four (A, B, C, and D) highly diverged sheep lineages were observed in Caucasus, 3 (A, B and C) in Central Asia, and 2 (A and B) in the eastern fringe of Europe, which included the area north and west of the Black Sea and the Ural Mountains. Only one example of Group D was detected. The other haplotype groups demonstrated signs of population expansion. Sequence variation within the lineages implied Group A to have expanded first. This group was the most frequent type only in Caucasian and Central Asian breeds. Expansion of Group C appeared most recently. The expansion of Group B involving Caucasian sheep took place at nearly the same time as the expansion of Group A. Group B expansion for the eastern European area started approximately 3,000 years after the earliest inferred expansion. An independent European domestication of sheep is unlikely. The distribution of Group A variation as well as other results are compatible with the Near East being the domestication site. Groups C and D may have been introgressed later into a domestic stock, but larger samples are needed to infer their geographical origin. The

    Background Although vitamin D receptor (VDR) polymorphisms have been shown to be associated with abnormal glucose metabolism, the reported polymorphisms are unlikely to have any biological consequences. The VDR gene has two potential translation initiation sites. A T-to-C polymorphism has been noted in the first ATG (f allele), abolishing the first translation initiation site and resulting in a peptide lacking the first three amino acids (F allele). We examined the role of this polymorphism in insulin sensitivity and beta cell function. This study included 49 healthy Caucasian subjects (28 females, age 28 ± 1 years old, body mass index 24.57 ± 0.57 kg/m2, waist-hip ratio 0.81 ± 0.01 cm/cm). They were all normotensive (less than 140/90 mmHg) and glucose tolerant, which was determined by a standard 75-gm oral glucose tolerance test. Their beta cell function (%B) and insulin sensitivity (%S) were calculated based on the Homeostasis Model Assessment (HOMA). Their genotypes were determined by a polymerase chain reaction-restriction fragment length polymorphism analysis. Phenotypes were compared between genotypic groups. Results There were 18 FF, 21 Ff, and 10 ff subjects. Since only 10 ff subjects were identified, they were pooled with the Ff subjects during analyses. The FF and Ff/ff groups had similar glucose levels at each time point before and after a glucose challenge. The Ff/ff group had higher insulin levels than the FF group at fasting (P=0.006), 30 minutes (P=0.009), 60 minutes (P=0.049), and 90 minutes (P=0.042). Furthermore, the Ff/ff group also had a larger insulin area under the curve than the FF group (P=0.009). While no difference was noted in %B, the Ff/ff group had a lower %S than the FF group (0.53 vs. 0.78, P=0.006). A stepwise regression analysis confirmed that the Fok I polymorphism was an independent determinant for %S, accounting for 29.3% of variation in %S when combined with waist-hip ratio. Conclusions We report that the Fok I polymorphism

    Abstract Asians have a lower prevalence of hypertensive disorders of pregnancy than Caucasians. Since sympathetic overactivity and dysregulation of the renal–adrenal system (e.g. low aldosterone levels) have been found in preeclamptic women, we hypothesized that Asians have lower muscle sympathetic nerve activity (MSNA) and greater aldosterone concentrations during normal pregnancy than Caucasians. In a prospective study, blood pressure (BP), heart rate (HR), and MSNA were measured during supine and upright tilt (30 deg and 60 deg for 5 min each) in 9 Asians (32 ± 1 years (mean ± SEM)) and 12 Caucasians (29 ± 1 years) during pre-, early (≤8 weeks of gestation) and late (32–36 weeks) pregnancy, and post-partum (6–10 weeks after delivery). Supine MSNA increased with pregnancy in both groups (P < 0.001); it was significantly lower in Asians than Caucasians (14 ± 3 vs. 23 ± 3 bursts min−1 and 16 ± 5 vs. 30 ± 3 bursts min−1 in early and late pregnancy, respectively; P = 0.023). BP decreased during early pregnancy (P < 0.001), but was restored during late pregnancy. HR increased during pregnancy (P < 0.001) with no racial difference (P = 0.758). MSNA increased during tilting and it was markedly lower in Asians than Caucasians in late pregnancy (31 ± 6 vs. 49 ± 3 bursts min−1 at 60 deg tilt; P = 0.003). Upright BP was lower in Asians, even in pre-pregnancy (P = 0.006), and this racial difference persisted during pregnancy. Direct renin and aldosterone increased during pregnancy (both P < 0.001); these hormones were greater in Asians (P = 0.086 and P = 0.014). Thus, Asians have less sympathetic activation but more upregulated renal–adrenal responses than Caucasians during pregnancy. These results may explain, at least in part, why Asian women are at low risk of hypertensive disorders in pregnancy. Key points Asian women have a lower prevalence of hypertensive disorders of pregnancy than Caucasian

    Despite progress in breast cancer treatment, disparity persists in survival time between African American (AA) and Caucasian women in the US. Tumor stage and tumor grade are the major prognostic factors that define tumor aggressiveness and contribute to racial disparity between AA and Caucasian women. Studying the interaction of race with tumor grade or stage may provide further insights into the role of intrinsic biological aggressiveness in disecting the AA-Caucasian survival disparity. Therefore, the current study was performed to evaluate the interaction of race with tumor grade and stage at diagnosis regarding survival in a cohort of patients treated at the Winthrop P. Rockefeller Cancer Institute of the University of Arkansas for Medical Sciences (Little Rock, AR, USA). The cohort included 1,077 patients, 208 (19.3%) AA and 869 (80.7%) Caucasian, diagnosed with breast cancer between January 1997 and December 2005. Kaplan-Meier survival plots were generated and Cox regressions were performed to analyze the associations of race with breast cancer-specific survival time. Over a mean follow-up time of 1.5 years, AA women displayed increased mortality risk due to breast cancer-specific causes [hazard ratio (HR), 1.74; 95% confidence interval (CI), 1.23–2.46]. The magnitude of racial disparity varied strongly with tumor grade (race-x-grade interaction; P<0.001). No significant interaction was observed between race and tumor stage or race and age at diagnosis. Among women diagnosed with grade I tumors, the race disparity in survival time after controlling for tumor stage and age was strong (HR, 9.07; 95% CI, 2.11–38.95), but no significant AA-Caucasian disparity was observed among women with higher-grade tumors. The data suggest that, when diagnosed with grade I breast cancer, AA may experience poorer survival outcomes compared with Caucasian patients, regardless of tumor stage or age. The findings potentially provide significant clinical and public health

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to religious

    There is increasing evidence that vitamin D can protect against breast cancer. The actions of vitamin D are mediated via the vitamin D receptor (VDR). We have investigated whether polymorphisms in the VDR gene are associated with altered breast cancer risk in a UK Caucasian population. We recruited 241 women following a negative screening mammogram and 181 women with known breast cancer. The VDR polymorphism Bsm I, an intronic 3' gene variant, was significantly associated with increased breast cancer risk: odds ratio bb vs BB genotype = 2.32 (95% CI, 1.23-4.39). The Bsm I polymorphism was in linkage disequilibrium with a candidate translational control site, the variable length poly (A) sequence in the 3' untranslated region. Thus, the 'L' poly (A) variant was also associated with a similar breast cancer risk. A 5' VDR gene variant, Fok I, was not associated with breast cancer risk. Further investigations into the mechanisms of interactions of the VDR with other environmental and/or genetic influences to alter breast cancer risk may lead to a new understanding of the role of vitamin D in the control of cellular and developmental pathways.

    Previous studies of pulmonary diffusing capacity in healthy children primarily focused upon Caucasian (C) subjects. Since lung volumes in African-Americans (AA) are smaller than lung volumes in C subjects of the same height, diffusing capacity values in AA children might be interpreted as low or abnormal using currently available equations without adjusting for race. Healthy AA (N = 151) and C (N = 301) children between 5 and 18 years of age performed acceptable measurements of single breath pulmonary diffusing capacity for carbon monoxide (DLCO ) and alveolar volume (VA ) according to current ATS/ERS guidelines. The natural log of DLCO and VA were associated with height, gender, age, and race; AA children had lower DLCO and VA compared to C children. Adjustment of DLCO for Hemoglobin (Hgb) resulted in no significant difference in DLCO among these healthy subjects with normal Hgb. In summary, we report prediction equations for DLCO and VA that include adjustment for race (C; AA) demonstrating that AA have lower DLCO and VA compared to C children for the same height, gender, and age.

    Post-exercise hypotension (PEH) is widely observed in Caucasians (CA) and is associated with histamine receptors 1- and 2- (H1R and H2R) mediated post-exercise vasodilation. However, it appears that blacks (BL) may not exhibit PEH following aerobic exercise. Hence, this study sought to determine the extent to which BL develop PEH, and the contribution of histamine receptors to PEH (or lack thereof) in this population. Forty-nine (22 BL, 27 CA) young and healthy subjects completed the study. Subjects were randomly assigned to take either a combined H1R and H2R antagonist (fexofenadine and ranitidine) or a control placebo. Supine blood pressure (BP), cardiac output and peripheral vascular resistance measurements were obtained at baseline, as well as at 30 min, 60 min and 90 min after 45 min of treadmill exercise at 70% heart rate reserve. Exercise increased diastolic BP in young BL but not in CA. Post-exercise diastolic BP was also elevated in BL after exercise with histamine receptor blockade. Moreover, H1R and H2R blockade elicited differential responses in stroke volume between BL and CA at rest, and the difference remained following exercise. Our findings show differential BP responses following exercise in BL and CA, and a potential role of histamine receptors in mediating basal and post-exercise stroke volume in BL. The heightened BP and vascular responses to exercise stimulus is consistent with the greater CVD risk in BL. PMID:27074034

    The aim of the study was to investigate the bioequivalence of a generic product of 8 mg film-coated tablets (test) to the branded product (reference) at the same strength in order to apply for regulatory approval. The secondary objective of the study was to compare the tolerability of both products. A double blinded, randomized, cross-over, 2-period, comparative study was conducted in healthy Caucasian volunteers under fasting conditions. A single oral dose administration of the test or reference product was followed by a 7-day wash-out period. The ondansetron concentration was determined using a validated high performance liquid chromatography with a UV detection method. The 90% confidence interval of the point estimate (test over reference products) for C(max) and AUC(0-t) fell within the 80.00-125.00% acceptance range. The results of the study indicate that the film-coated tablets of Ondatron 8 mg manufactured by Tarchomińskie Zakłady Farmaceutyczne Polfa S.A. (test product) are bioequivalent to those of Zofran manufactured by GlaxoSmithKline Export Ltd (reference product). Both products were well tolerated. PMID:24132707

    Purpose This study compared in vivo kinematic differences between Caucasian and South Korean patients after a posterior-substituting total knee arthroplasty (PS-TKA). Materials and Methods In vivo motions of 9 Caucasian and 13 South Korean knees with a PS-TKA during weight bearing single leg lunge were determined using a dual fluoroscopic imaging technique. Normalized tibiofemoral condylar motions and articular contact locations were analyzed. Results Femoral condylar motions of the two groups showed a similar trend in anteroposterior translation, but the South Korean patients were more anteriorly positioned than the Caucasian patients at low flexion and maximal flexion angles in both medial and lateral compartments (p<0.05). Mediolateral femoral condyle translations were similar between the two groups. For tibiofemoral articular contact kinematics, the South Korean patients had significantly more anterior contact locations at the medial compartment at low flexion angles, and more lateral contact locations at the lateral compartment at 0° and 90° flexion compared to the Caucasian patients (p<0.05). The South Korean patients had significantly larger distances between the medial and lateral contact locations at 60° and 90° flexion compared to the Caucasian patients (p<0.05). Conclusions The study revealed that while the Caucasian and South Korean knees had similar femoral condylar motions, after PS-TKA the South Korean patients showed different articular contact point kinematics compared to the Caucasian patients.

    mtDNA sequence variation was examined in 175 Caucasians from the United States and Canada by PCR amplification and high-resolution restriction-endonuclease analysis. The majority of the Caucasian mtDNAs were subsumed within four mtDNA lineages (haplogroups) defined by mutations that are rarely seen in Africans and Mongoloids. The sequence divergence of these haplogroups indicates that they arose early in Caucasian radiation and gave raise to modern European mtDNAs. Although ancient, none of these haplogroups is old enough to be compatible with a Neanderthal origin, suggesting that Homo sapiens sapiens displaced H. s. neanderthaliensis, rather than mixed with it. The mtDNAs of one of these haplogroups have a unique homoplasmic insertion between nucleotide pair (np) 573 and np 574, within the D-loop control region. This insertion makes these mtDNAs prone to a somatic mutation that duplicates a 270-bp portion of the D-loop region between np 309 and np 572. This finding suggests that certain nonpathogenic mtDNA mutations could predispose individuals to mtDNA rearrangements. Images Figure 3 Figure 4 PMID:7942855

    Microcystic adnexal carcinoma (MAC) is extremely rare among Asians, with the majority of cases presenting in Caucasian individuals. The current study describes the case of a 38-year-old Chinese woman who presented with a 10 year history of a mass in the upper lip. A biopsy resulted in a diagnosis of MAC. The patient underwent complete surgical resection and the tumor was successfully excised. During 6 months of follow-up, there was no evidence of recurrence. To the best of our knowledge, the present case is the first Chinese case to be reported in the English literature, and is presented with the aim of increasing the awareness and aiding in the management of MAC in non-Caucasian populations.

    Introduction We report the first known case of human T-lymphotropic virus type I associated myelopathy/tropical spastic paraparesis in an Australian Caucasian, a disease reported in Aboriginal and immigrant populations where the virus is often endemic. Case presentation A 41-year-old Caucasian Australian man had a 3-year background of progressive functional decline from a myelopathy with spastic paraparesis and sphincteric dysfunction. Conclusions Although studies have shown a very low prevalence of human T-lymphotropic virus type I in the greater Australian population, increased focus on Aboriginal health, and the expanding diversity and integration of the Australian population means that presentation of human T-lymphotropic virus type I-associated disease is likely to increase.

    Elevated circulating levels of the adrenal androgen dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are associated with increased breast cancer risk in prospective studies. Genetic variants in hypothalamic-pituitary-adrenal (HPA) axis genes may contribute to these circulating hormone levels, and consequently to breast cancer risk. No previous studies have examined the effects of genetic variants in HPA axis genes on breast cancer risk. We evaluated the associations of 49 single nucleotide polymorphisms (SNPs) in five HPA axis genes (NR3C1, NR3C2, CRH, CRHR1, and CRHBP) with the risk of breast cancer in the Women's Insights and Shared Experiences (WISE) Study of Caucasians (346 cases and 442 controls), as well as African Americans (149 cases and 246 controls). Of the 49 SNPs evaluated, one showed a nominal significant association (P for trend < 0.05) with breast cancer risk among Caucasians, and another two among African Americans. The age-adjusted additive odds ratio (OR) (95% confidence interval (95% CI)) of the SNP rs11747190[A] in the CRHBP gene for the risk of breast cancer among Caucasian women was 1.45 (1.09-1.94). The age-adjusted additive ORs (95% CIs) of two SNPs (CRHBP rs1700688[T] and CRHR1 rs17689471[C]) for the risk of breast cancer among African American women were 1.84 (1.13-2.98) and 2.48 (1.20-5.13), respectively. However, these SNPs did not show significant associations after correction for multiple testing. Our findings do not provide strong supportive evidence for the contribution of genetic variants in these HPA axis genes to the risk of developing breast cancer in either Caucasians or African Americans.

    To discover susceptibility genes of late-onset Alzheimer’s disease (LOAD), we conducted a 3-stage genome-wide association study (GWAS) using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD), Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC). In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008) and controls (n = 1,016). Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values <2×10−5 were genotyped in a second Japanese sample (885 cases, 985 controls), and evidence of association was confirmed for one SORL1 SNP (rs3781834, P = 7.33×10−7 in the combined sample). Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls) and Caucasians (11,840 AD cases, 10,931 controls) revealed genome wide significance with rs11218343 (P = 1.77×10−9) and rs3781834 (P = 1.04×10−8). SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P = 1.71×10−5) and rs744373 near BIN1 (P = 1.39×10−4). The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations. PMID:23565137

    Over the past four decades in the United States, there has been a divergent trend in mortality rates between African-Americans and Caucasians with colorectal cancer (CRC). Rates among Caucasians have been steadily declining, whereas rates among African-Americans have only started a gradual decline in recent years. We reviewed epidemiologic studies of CRC racial disparities between African-Americans and Caucasians, including studies from SEER and population-based cancer registries, Veterans Affairs (VA) databases, healthcare coverage databases, and university and other medical center data sources. Elevated overall and stage-specific risks of CRC mortality and shorter survival for African-Americans compared with Caucasians were reported across all data sources. The magnitude of racial disparities varied across study groups, with the strongest associations observed in university and non-VA hospital-based medical center studies, while an attenuated discrepancy was found in VA database studies. An advanced stage of disease at the time of diagnosis among African-Americans is a major contributing factor to the racial disparity in survival. Several studies, however, have shown that an increased risk of CRC death among African-Americans remains even after controlling for tumor stage at diagnosis, socioeconomic factors, and comorbidity. Despite advances in treatment, improvements in the standard of care, and increased screening options, racial differences persist in CRC mortality and survival. Therefore, continued research efforts are necessary to disentangle the clinical, social, biological, and environmental factors that constitute the racial disparity. In addition, results across data sources should be considered when evaluating racial differences in cancer outcomes. PMID:18048968

    Leber hereditary optic neuropathy (LHON) is a type of blindness caused by mtDNA mutations. Three LHON mtDNA mutations at nucleotide positions 3460, 11778, and 14484 are specific for LHON and account for 90% of worldwide cases and are thus designated as {open_quotes}primary{close_quotes} LHON mutations. Fifteen other {open_quotes}secondary{close_quotes} LHON mtDNA mutations have been identified, but their pathogenicity is unclear. mtDNA haplotype and phylogenetic analysis of the primary LHON mutations in North American Caucasian patients and controls has shown that, unlike the 3460 and 11778 mutations, which are distributed throughout the European-derived (Caucasian) mtDNA phylogeny, patients containing the 14484 mutation tended to be associated with European mtDNA haplotype J. To investigate this apparent clustering, we performed {chi}{sup 2}-based statistical analyses to compare the distribution of LHON patients on the Caucasian phylogenetic tree. Our results indicate that, unlike the 3460 and 11778 mutations, the 14484 mutation was not distributed on the phylogeny in proportion to the frequencies of the major Caucasian mtDNA haplogroups found in North America. The 14484 mutation was next shown to occur on the haplogroup J background more frequently that expected, consistent with the observation that {approximately}75% of worldwide 14484-positive LHON patients occur in association with haplogroup J. The 11778 mutation also exhibited a moderate clustering on haplogroup J. These observations were supported by statistical analysis using all available mutation frequencies reported in the literature. This paper thus illustrates the potential importance of genetic background in certain mtDNA-based diseases, speculates on a pathogenic role for a subset of LHON secondary mutations and their interaction with primary mutations, and provides support for a polygenic model for LHON expression in some cases. 18 refs., 3 tabs.

    Circulating insulin-like growth factor-one (IGF-I) and IGF binding protein-3 (IGFBP-3) levels have been associated with common diseases. Although family-based studies suggest that genetic variation contributes to circulating IGF-I and IGFBP-3 levels, analyses of associations with multiple IGF-I and IGFBP-3 single nucleotide polymorphisms (SNPs) have been limited, especially among African Americans. We evaluated 30 IGF-I and 15 IGFBP-3 SNPs and estimated diplotypes in association with plasma IGF-I and IGFBP-3 among 984 premenopausal African American and Caucasian women. In both races, IGFBP-3 rs2854746 (Ala32Gly) was positively associated with plasma IGFBP-3 (CC versus GG mean difference among Caucasians = 631 ng/ml, 95% confidence interval: 398, 864; African Americans = 897 ng/ml, 95% confidence interval: 656, 1138), and IGFBP-3 diplotypes with the rs2854746 GG genotype had lower mean IGFBP-3 levels than referent diplotypes with the CG genotype, while IGFBP-3 diplotypes with the CC genotype had higher mean IGFBP-3 levels. IGFBP-3 rs2854744 (−202 A/C) was in strong linkage disequilibrium with rs2854746 in Caucasians only, but was associated with plasma IGFBP-3 in both races. Eight additional IGFBP-3 SNPs were associated with 5% or greater differences in mean IGFBP-3 levels, with generally consistent associations between races. Twelve IGF-I SNPs were associated with 10% or greater differences in mean IGF-I levels, but associations were generally discordant between races. Diplotype associations with plasma IGF-I did not parallel IGF-I SNP associations. Our study supports that common IGFBP-3 SNPs, especially rs2854746, influence plasma IGFBP-3 levels among African Americans and Caucasians, but provides less evidence that IGF-I SNPs affect plasma IGF-I levels.

    The angiosperm female gametophyte is critical for plant reproduction. It contains the egg cell and central cell that become fertilized and give rise to the embryo and endosperm of the seed, respectively. Female gametophyte development begins early in ovule development with the formation of a diploid megaspore mother cell that undergoes meiosis. One resulting haploid megaspore then develops into the female gametophyte. Genetic and epigenetic processes mediate specification of megaspore mother cell identity and limit megaspore mother cell formation to a single cell per ovule. Auxin gradients influence female gametophyte polarity and a battery of transcription factors mediate female gametophyte cell specification and differentiation. The mature female gametophyte secretes peptides that guide the pollen tube to the embryo sac and contains protein complexes that prevent seed development before fertilization. Post-fertilization, the female gametophyte influences seed development through maternal-effect genes and by regulating parental contributions. Female gametophytes can form by an asexual process called gametophytic apomixis, which involves formation of a diploid female gametophyte and fertilization-independent development of the egg into the embryo. These functions collectively underscore the important role of the female gametophyte in seed and food production. PMID:22303279

    Multiple sclerosis (MS) is a demyelinating disease in the central nervous system. Genetics have been considered as a leading factor in the prevalence and disease course of MS. We have presented an informatics-based eFolder system for integrating patients' clinical data with MR images and lesion quantification results. The completed eFolder system has been designed and developed in aiding to evaluate disease manifestation differences in Hispanic and Caucasian MS patients. MS lesion data, as shown in MRI, can be extracted by the 3-D automatic lesion detection tool in the eFolder, and data storing and mining tools in eFolder is able to extract and compare data from individual patients. The computer-aided detection (CAD) algorithm has been modified and enhanced to include spatial information as detection criteria. For this study, 36 Caucasian MS patients and 36 matched Hispanic patients have been selected. Most recent MR images of the patients are collected, and images are evaluated both by the CAD tool in the eFolder and radiologists. The results are compared between Caucasian and Hispanic patients and statistically evaluated to see if the two populations have significant difference in lesion presentations. The results can be used to evaluate differences in the two groups of patients and to evaluate the new CAD algorithm's performance with radiologists' contours. Significant findings can further evaluate effectiveness of MS eFolder in MS-related research.

    Chronic rhinosinusitis with nasal polyps (CRSwNP) in Caucasians is a chronic Th2 inflammatory disease of the nasal and paranasal mucosa and the recruitment of leukocytes to the site of inflammation is poorly understood. We studied mRNA and protein expression profiles of adhesion molecules in nasal polyp and associated inferior turbinate tissues using molecular, biochemical, and immunohistological methods. Analysis showed a strongly decreased E-selectin expression in nasal polyps with a significant difference between eosinophil and neutrophil counts in nasal polyps and balanced counts in inferior turbinates. E-selectin expression is known to be downregulated in a Th2 milieu and has an essential role in immunosurveillance by locally activating neutrophil arrest and migratory function. A downregulation of E-selectin may come along with an immune imbalance in Caucasian nasal polyps due to a significant inhibition of neutrophil recruitment. Therefore, we suggest that an upregulation of E-selectin and the associated influx of neutrophils may play a significant role in the resolution of inflammation as well as for the pathophysiology of nasal polyps of Caucasian chronic rhinosinusitis patients.

    During mild cold exposure, non-shivering thermogenesis increases to maintain core body temperature by increasing utilization of substrates, especially fatty acids (FA), ultimately affecting lipid-associated metabolites. We aimed to investigate whether mild cooling induces changes in other metabolites and whether this response differs between white Caucasians and South Asians, who have a disadvantageous metabolic phenotype. 12 lean male Dutch white Caucasians and 12 matched Dutch South Asians were exposed to mild cold. Before and after 100 min exposure, serum samples were collected for analysis of 163 metabolites and 27 derived parameters using high throughput metabolomics. The overall response to mild cooling between both ethnicities was not different, therefore the data were pooled. After Bonferroni correction, mild cooling significantly changed 44 of 190 (23%) metabolic parameters. Specifically, cooling increased 19 phosphatidylcholine (PC) species, only those containing very long chain FAs, and increased the total class of PC containing mono-unsaturated FAs (+12.5%). Furthermore, cooling increased 10 sphingomyelin species as well as the amino acids glutamine (+18.7%), glycine (+11.6%) and histidine (+10.6%), and decreased short-chain (C3 and C4) acylcarnitines (-17.1% and -19.4%, respectively). In conclusion, mild cooling elicits substantial effects on serum metabolites in healthy males, irrespective of white Caucasian or South Asian ethnicity. PMID:26384768

    B and T lymphocyte attenuator (BTLA) is one of the members of immunoglobulin superfamily which, like CTLA-4 and PD-1, is involved in down regulation of immune response. Despite the important role of BTLA in maintaining immune homeostasis, relatively little studies were devoted to the relationship of polymorphisms in the gene encoding BTLA with susceptibility to autoimmune disease and cancer. Moreover, all published works were done in Asian populations. BTLA gene is located on chromosome 3 in q13.2 and consists of five exons. The aim of this study was to investigate the alleles, genotypes and haplotypes frequency of selected BTLA gene polymorphisms in Caucasian population originating from Poland. For this study, the single-nucleotide polymorphisms (SNPs) were chosen on the basis of literature data. Additionally, the tag dSNP under linkage equilibrium r (2) > 0.8 and available at the National Center for Biotechnology Information (NCBI) for Caucasian population of rare alleles at a frequency greater than 5 % have been chosen using the NCBI database. The ten BTLA SNPs investigated were: rs1844089, rs2705535, rs9288952, rs9288953, rs1982809, rs2633580, rs2705511, rs2705565, rs76844316, rs16859633. For all SNPs selected on the basis of literature data the significantly different distributions of genotypes between Asian and Caucasian populations were observed. PMID:25182981

    A theoretical framework, which included perspectives of individualism-collectivism and self-efficacy, was used to investigate factors associated with sexual risk practice among gay Asian and Caucasian men. "Risk" was defined as unprotected anal intercourse with any casual partner or with a regular partner whose HIV status was not concordant with the participant's. Altogether, 201 Caucasian and 199 Asian gay men, largely recruited from gay social venues in inner Sydney, completed an anonymous questionnaire. Most participants were gay self-identified and gay community attached, and more than half of the Asian men had been living in Sydney for at least 3 years. Overall, the Asian men were more collectivist oriented and the Caucasian men more individualist oriented. Data analyses revealed that higher self-efficacy in avoiding casual risk encounters and smaller proportion of gay friends were associated with less risk. The inclusion of individualism-collectivism and social cognitive variables in the examination of sexual risk practices among gay men from different cultural backgrounds holds promise. PMID:15058711

    Oculocutaneous albinism (OCA) is a genetically heterogeneous group of disorders characterized by absent or reduced pigmentation of the skin, hair, and eyes. In humans, four genes have been associated with "classical" OCA and another 12 genes with syndromic forms of OCA. To assess the prevalence of different forms of OCA and different gene mutations among non-Hispanic Caucasian patients, we performed DNA sequence analysis of the four genes associated with "classical" OCA (TYR, OCA2, TYRP1, SLC45A2), the two principal genes associated with syndromic OCA (HPS1, HPS4), and a candidate OCA gene (SILV), in 121 unrelated, unselected non-Hispanic/Latino Caucasian patients carrying the clinical diagnosis of OCA. We identified apparent pathologic TYR gene mutations in 69% of patients, OCA2 mutations in 18%, SLC45A2 mutations in 6%, and no apparent pathological mutations in 7% of patients. We found no mutations of TYRP1, HPS1, HPS4, or SILV in any patients. Although we observed a diversity of mutations for each gene, a relatively small number of different mutant alleles account for a majority of the total. This study demonstrates that, contrary to long-held clinical lore, OCA1, not OCA2, is by far the most frequent cause of OCA among Caucasian patients. PMID:18463683

    Breast cancer is a commonly diagnosed malignancy and the second leading cause of cancer-related death among American women today. Despite the lower incidence of breast cancer among African American women, they are more likely to die from the disease each year than their white counterparts. We present a retrospective cohort study of the tumor registry data from electronic medical records of patients diagnosed with breast cancer at the University of Florida Health, Jacksonville from 2000 to 2005. A total of 907 patients were diagnosed with breast cancer; 445 patients with invasive breast cancer had complete medical records and were selected for this review. Much like previously published research, we found that African American patients presented with a more advanced stage and aggressive subtype of breast cancer than white patients, and were less likely to have health insurance. However, we have yet to determine if universal health care insurance can lead to improved health care access, better breast cancer awareness, and an enhanced attitude toward breast cancer screenings. Such factors would ultimately lead to an earlier diagnosis and better outcomes in both African American and white patients. We plan to investigate this critical issue in a follow-up study (BRCA-2; Breast Cancer and Racial Disparity Between Caucasian and African American Women, Part 2), which will begin a few years after the complete implementation of the universal health care law enacted by President Obama in 2010. The higher frequency of aggressive tumor subtypes in African American women warrants more attention. We suggest further research to determine whether decreasing the initial age for screening or increasing the frequency of mammograms in African American women would improve breast cancer outcomes. This study underscores the importance of identifying and preventing obstacles in routine breast cancer screening, as well as increasing breast cancer awareness. PMID:24518421

    Background Landsteiner-Wiener (LW) is the human blood group system no. 16, which comprises 2 antithetical antigens, LWa and LWb and the high prevalence antigen LWab. LW is encoded by the Intracellular Adhesion Molecule 4 (ICAM4) gene. The ICAM4 protein is part of the Rhesus complex in the red cell membrane and is involved in cell-cell adhesion. Methods We developed a method to sequence the whole 1.9 kb ICAM4 gene from genomic DNA in 1 amplicon. We determined the nucleotide sequence of exons 1 to 3, the 2 introns and 402 bp 5′-UTR and 347 bp 3′-UTR in 97 Caucasian and 91 African American individuals. Results Seven variant ICAM4 alleles were found, distinct from the wild type ICAM4 allele (GenBank KF712272), known as LW*05 and encoding LWa. An effect of the LWa/LWb amino acid substitution on the protein structure was predicted by 2 of the 3 computational modeling programs used. Conclusions We describe a practical approach for sequencing and determining the ICAM4 alleles using genomic DNA. LW*05 is the ancestral allele, which had also been observed in a Neandertal sample. All 7 variant alleles are immediate derivatives of the prevalent LW*05 and caused by 1 single nucleotide polymorphism (SNP) in each allele. Our data were consistent with the NHLBI GO Exome Sequencing Project (ESP) and the dbSNP databases, as all SNPs had been observed before. Our study has the advantage over the other databases in that it adds haplotype (allele) information for the ICAM4 gene, clinically relevant in the field of transfusion medicine. PMID:24673173

    2015-01-01

    The problem of species and speciation is considered using as a model the cryptic species of rodents inhabiting the Caucasus, the mountain chain with prominent altitude environmental gradient and insular pattern of mountain habitats. These circumstances open additional possibilities for the choice of species conception (biological or phylogenetic), exploration of ancestry pathways (sympatric or allopatric speciation) of model cryptic species groups, and testing the 'refuge' hypothesis. As model species, sibling-species Sicista from the group 'caucasica' (a group of unstriped birch mice) and representatives of the vole subspecies Terricola (Microtus, Arvicolinae) were used. Based on the new data on karyology, nucleotide sequences of mitochondrial gene cytb, multivariate statistical analysis of odontologic traits, and biogeography of sibling-species Sicista from the group 'caucasica' and voles from subspecies Terricola (Microtus, Arvicolinae), their evolutionary history is reconstructed and applicable species concepts are examined. For the present sibling-species Sicista from the group 'caucasica' the allopatric dispersion is typical, which agrees with the hypothesis of speciation in refuges. The sympatry of Terricola sibling-species in the Caucasus is considered as being secondary, and their phenotypic likeness--as an adaptation to similar environmental conditions. Affirmed coexistence of sibling-species Microtus (Terricola) majori and Microtus (Terricola) daghestanicus in the Caucasus (without their hybridization) supports the biological conception of species. The existence of Sicista allospecies from the group of Caucasian unstriped birch mice is best conformed to the phylogenetic conception. However, the high level of chromosomal differences between sibling-species and, in particular, between extreme variants of common evolutionary line (Sicista kazbegica, Sicista kluchorica) does not contradict the biological conception of species.

    2013-01-01

    Background Cleidocranial dysplasia (CCD) is a rare congenital autosomal dominant skeletal disorder. The disorder is caused by heterozygosity of mutations in human RUNX2, which is present on the short arm of chromosome 6p21. The incidence of CCD is one per million births. CCD appears spontaneously with no apparent genetic cause in approximately 40% of affected patients, and one in three patients has unaffected parents. The most prevalent features associated with CCD are aplastic or hypoplastic clavicles, supernumerary teeth, failed eruption of permanent teeth, and a hypoplastic maxilla. Case presentation A 13-year-old Caucasian boy presented with a chief complaint of delayed eruption of the permanent anterior teeth. The patient was subsequently diagnosed with CCD based on the clinical examination, panoramic X-ray, anterior-posterior and lateral cephalogram, and chest radiograph findings. The details of this case are herein reported because of the extremely low incidence of this disorder. Conclusions CCD is of clinical importance in dentistry and medicine because it affects the bones and teeth and is characterized by many changes in skeletal patterning and growth. Particularly in dentistry, CCD is of great clinical significance because is associated with delayed ossification of the skull sutures, delayed exfoliation of the primary teeth, lack of permanent teeth eruption, multiple supernumerary teeth, and morphological abnormalities of the maxilla and mandible. Patients with CCD seek treatment mainly for dental problems. Knowledge of the pathogenesis, clinical characteristics, and diagnostic tools of CCD will enable clinicians to render the appropriate treatment to improve function and aesthetics. Early diagnosis of CCD is crucial for timely initiation of an appropriate treatment approach. PMID:23289840

    Summary Lipoid congenital adrenal hyperplasia (lipoid CAH), the most severe form of CAH, is most commonly caused by mutations in steroidogenic acute regulatory protein (STAR), which is required for the movement of cholesterol from the outer to the inner mitochondrial membranes to synthesize pregnenolone. This study was performed to evaluate whether the salt-losing crisis and the adrenal inactivity experienced by a Scandinavian infant is due to a de novo STAR mutation. The study was conducted at the University of North Dakota, the Mercer University School of Medicine and the Memorial University Medical Center to identify the cause of this disease. The patient was admitted to a pediatric endocrinologist at the Sanford Health Center for salt-losing crisis and possible adrenal failure. Lipoid CAH is an autosomal recessive disease, we identified two de novo heterozygous mutations (STAR c.444C>A (STAR p.N148K) and STAR c.557C>T (STAR p.R193X)) in the STAR gene, causing lipoid CAH. New onset lipoid CAH can occur through de novo mutations and is not restricted to any specific region of the world. This Scandinavian family was of Norwegian descent and had lipoid CAH due to a mutation in S TAR exons 4 and 5. Overexpression of the STAR p.N148K mutant in nonsteroidogenic COS-1 cells supplemented with an electron transport system showed activity similar to the background level, which was ∼10% of that observed with wild-type (WT) STAR. Protein-folding analysis showed that the finger printing of the STAR p.N148K mutant is also different from the WT protein. Inherited STAR mutations may be more prevalent in some geographical areas but not necessarily restricted to those regions. Learning points STAR mutations cause lipoid CAH.This is a pure population from a caucasian family.Mutation ablated STAR activity.The mutation resulted in loosely folded conformation of STAR.

    BACKGROUND Meningomyelocele (MM) is a common human birth defect. MM is a disorder of neural development caused by contributions from genes and environmental factors that result in the neural tube defect and lead to a spectrum of physical and neurocognitive phenotypes. METHODS A multi-disciplinary approach has been taken to develop a comprehensive understanding of MM through collaborative efforts from investigators specializing in genetics, development, brain imaging, and neurocognitive outcome. Patients have been recruited from five different sites: Houston and the Texas-Mexico border area; Toronto, Canada; Los Angeles, California; and Lexington, Kentucky. Genetic risk factors for MM have been assessed by genotyping and association testing using the transmission disequilibrium test. RESULTS A total of 509 affected child/parent trios and 309 affected child/parent duos have been enrolled to date for genetic association studies. Subsets of the patients have also been enrolled for studies assessing development, brain imaging, and neurocognitive outcomes. The study recruited two major ethnic groups with 45.9% Hispanics of Mexican descent and 36.2% North American Caucasians of European descent. The remaining patients are African American, South and Central American, Native American and Asian. Studies of this group of patients have already discovered distinct corpus callosum morphology and neurocognitive deficits that associate with MM. We have identified maternal MTHFR 667T allele as a risk factor for MM. In addition, we also found that several genes for glucose transport and metabolism are potential risk factors for MM. CONCLUSIONS The enrolled patient population provides a valuable resource for elucidating the disease characteristics and mechanisms for MM development. PMID:18937358

    Objective to assess Female Sexual Function Index (FSFI) scores and delay to resume sexual activity associated with a previous severe maternal morbidity. Method This was a multidimensional retrospective cohort study. Women who gave birth at a Brazilian tertiary maternity between 2008 and 2012 were included, with data extraction from the hospital information system. Those with potentially life-threatening conditions and maternal near miss episodes (severe maternal morbidity) were considered the exposed group. The control group was a random sample of women who had had uncomplicated pregnancy. Female sexual function was evaluated through FSFI questionnaire, and general and reproductive aspects were addressed through specific questions. Statistical analyses were performed using Mann-Whitney and Pearson´s Chi-square for bivariate analyses. Logistic regression was used to identify variables independently associated with lower FSFI scores. Results 638 women were included (315 at exposed and 323 at not exposed groups). The majority of women were under 30 years-old in the control group and between 30 and 46 years-old in the exposed group (p = 0.003). Women who experienced severe maternal morbidity (SMM) had statistically significant differences regarding cesarean section (82.4% versus 47.1% among deliveries without complications, p<0.001), and some previous pathological conditions. FSFI mean scores were similar among groups ranging from 24.39 to 24.42. It took longer for exposed women to resume sexual activity after index pregnancy (mean 84 days after SMM and 65 days for control group, p = 0.01). Multiple analyses showed no significant association of FSFI below cut-off value with any predictor. Conclusion FSFI scores were not different in both groups. However, they were lower than expected. SMM delayed resumption of sexual activity after delivery, beyond postpartum period. However, the proportion of women in both groups having sex at 3 months after delivery was similar

    Recently an association was demonstrated between the single nucleotide polymorphism (SNP), rs9939609, within the FTO locus and obesity as a consequence of a genome wide association (GWA) study of type 2 diabetes in adults. We examined the effects of two perfect surrogates for this SNP plus 11 other SNPs at this locus with respect to our childhood obesity cohort, consisting of both Caucasians and African Americans (AA). Utilizing data from our ongoing GWA study in our cohort of 418 Caucasian obese children (BMI>or=95th percentile), 2,270 Caucasian controls (BMI<95th percentile), 578 AA obese children and 1,424 AA controls, we investigated the association of the previously reported variation at the FTO locus with the childhood form of this disease in both ethnicities. The minor allele frequencies (MAF) of rs8050136 and rs3751812 (perfect surrogates for rs9939609 i.e. both r(2) = 1) in the Caucasian cases were 0.448 and 0.443 respectively while they were 0.391 and 0.386 in Caucasian controls respectively, yielding for both an odds ratio (OR) of 1.27 (95% CI 1.08-1.47; P = 0.0022). Furthermore, the MAFs of rs8050136 and rs3751812 in the AA cases were 0.449 and 0.115 respectively while they were 0.436 and 0.090 in AA controls respectively, yielding an OR of 1.05 (95% CI 0.91-1.21; P = 0.49) and of 1.31 (95% CI 1.050-1.643; P = 0.017) respectively. Investigating all 13 SNPs present on the Illumina HumanHap550 BeadChip in this region of linkage disequilibrium, rs3751812 was the only SNP conferring significant risk in AA. We have therefore replicated and refined the association in an AA cohort and distilled a tag-SNP, rs3751812, which captures the ancestral origin of the actual mutation. As such, variants in the FTO gene confer a similar magnitude of risk of obesity to children as to their adult counterparts and appear to have a global impact. PMID:18335027

    Female chimpanzees exhibit exceptionally slow rates of reproduction and raise their offspring without direct paternal care. Therefore, their reproductive success depends critically on long-term access to high-quality food resources over a long lifespan. Chimpanzee communities contain multiple adult males, multiple adult females and their offspring. Because males are philopatric and jointly defend the community range while most females transfer to new communities before breeding, adult females are typically surrounded by unrelated competitors. Communities are fission-fusion societies in which individuals spend time alone or in fluid subgroups, whose size depends mostly on the abundance and distribution of food. To varying extents in different populations, females avoid direct competition by foraging alone or in small groups in distinct, but overlapping core areas within the community range to which they show high fidelity. Although rates of aggression are low, females compete for space and access to food. High rank correlates with high reproductive success, and high-ranking females win direct contests for food and gain preferential access to resource-rich sites. Females are aggressive to immigrant females and even kill the newborn infants of community members. The intensity of such aggression correlates with population density. These patterns are compared to those in other species, including humans. PMID:24167307

    Cystic fibrosis (CF), caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, is one of the most common autosomal recessive diseases in Caucasians. We screened for the CFTR gene mutation in a Caucasian father with congenital bilateral absence of the vas deferens (CBAVD), a Taiwanese mother, and twins resulting from an intracytoplasmic single sperm injection (ICSI) procedure. DNA fragments that showed abnormal banding patterns on temporal temperature gradient gel electrophoresis analysis followed by analysis of DNA sequence was used. The Caucasian father with CBAVD had _F508 and p.L375F mutations. The two children were heterozygous for the _F508 and p.L375F mutations, respectively. Mutation analysis of the CFTR gene should always be recommended for infertile couples seeking ICSI. The possibility of the children resulting from ICSI being a victim or carrier of CBAVD or CF, especially when the father is Caucasian with CBAVD, should be discussed during genetic counseling.

    Antioxidant nutrient intervention strategies to ameliorate negative health factors are of notable research interest. Central to the thesis that antioxidant nutrients improve biological defense systems and provide health benefits is an accurate indication of daily antioxidant nutrient intake. Little information is available concerning these nutrient intakes among non-affluent women of the southern U.S. This study examines the 24-h intake of vitamins: A, E, C, -carotene, a-tocopherol, riboflavin, and minerals: zinc, selenium, copper, manganese, iron, and molybdenum among 259 Caucasian (CA) and African-American (AA) women from small urban communities. Women were non-pregnant females, 19-93 y of age. Statistical comparisons of nutrient intake were made by least squares means within age groups. Intakes were compared to various Dietary Reference Intakes including Recommended Daily Allowance (RDA) and Estimated Average Requirement (EAR) values as established by the U.S. National Research Council. Numerous dietary deficiencies in important antioxidant nutrients associated with metabolic antioxidant systems were identified. Few race-related differences were detected. Intake of vitamin A was generally within recommended levels while vitamin E intake was below the EAR. The vitamin precursors, -carotene and a-tocopherol, were significantly (P<0.05) below customary intakes at all ages. More than 60% of this population reported dietary copper, zinc, and selenium intakes below recommended levels. A lack of race differences for most nutrient intakes suggests similar socioeconomic or endogeneous regional factors. All women in this population reported dietary intakes of antioxidant vitamins and minerals below recommended values, conditions that could contribute to subsequent health risks unless nutrient-dense food choices and antioxidant supplementation are considered in their overall nutritional support.

    Objectives Aging signs can be classified into four main categories: wrinkles/texture, lack of firmness of cutaneous tissues (ptosis), vascular disorders, and pigmentation heterogeneities. During a lifetime, skin will change in appearance and structure not only because of chronological and intrinsic processes but also due to several external factors such as gravity, sun and ultraviolet exposure, and high levels of pollution; or lifestyle factors that have important and obvious effects on skin aging, such as diet, tobacco, illness, or stress. The effect of these external factors leads to progressive degradations of tegument that appear with different kinetics. The aim of this study was to clinically quantify the effect of sun exposure on facial aging in terms of the appearance of new specific signs or in terms of increasing the classical signs of aging. Materials and methods This study was carried out on 298 Caucasian women from 30 years to 78 years old. The participants were divided into two groups according to their sun exposure history: 157 women were characterized as sun-seeking, and the other 141 were classified as sun-phobic. This division was made possible by dermatologist grading of heliodermal status on the basis of several observations of classic criteria: wrinkles, sagging, pigmentation heterogeneities, vascular disorders, elastosis, and so on. This work was an opportunity to complete clinical photographic tools by adding in our portfolio new scales for signs observed in the two groups. Thus, 22 clinical parameters were investigated by a panel of twelve trained experts to characterize each woman’s face regarding standardized photographic scales, and thus describe the aging process. Results By calculating statistical correlations between the four clinical clusters (wrinkles/texture, ptosis, vascular disorders, and pigmentation disorders), and real age and apparent age on the one hand and heliodermal status on the other hand, we identified a link between

    Variability in peripheral Quantitative Computed Tomography (pQCT) measurement sites limits direct comparisons of results between studies. Further, it is unclear what estimates of bone strength are most indicative of changes due to aging, disease, or interventions. The purpose of this study was to examine age group and sex differences in tibia morphology. Additional purposes of this study were to determine which tibia site or sites are most sensitive for detecting age and sex differences. Methods Self-identifying Caucasian men (n=55) and women (n=59) ages 20-59 years and separated by decades had their non-dominant tibias measured with pQCT (Stratec XCT 3000) at every 10% of the limb length from 5%-85% (distal to proximal). Volumetric BMD and BMC of the total, cortical and trabecular bone were determined, as well as periosteal (PeriC) and endosteal (EndoC) circumferences, and cortical thickness (CTh). Results There were significant (p<0.01) site effects for all BMC, vBMD, PeriC and EndoC measures. Large sex differences (men>women) in Tot.BMC (21-28%) were paralleled by differences in Cort.BMC (21-25%) (p<0.01). Site*sex interaction effects were significant (p<0.05) for BMC (peak sex difference: 5%, 15%, 25%, 85% sites) and circumference (peak sex difference: 65% site) variables. CTh and total vBMD were lowest (p<0.05) in 50-59 yr group, and EndoC was highest in the 50-59 yr group. Site*age interactions existed for Cort.vBMD, Tot.BMC (85% site), and EndoC (25%, 35%, 55%-85% sites). Correcting for bone free lean body mass (BFLBM) greatly reduced sex differences, eliminating sex*site interaction effects, but sex main effects remained significant. Correcting for BFLBM did not eliminate age effects. Conclusion The magnitude of age and sex differences in tibia variables varied by measurement site demonstrating the need for standardization of measurement sites. PMID:22449446

  10. Identification of genetic polymorphisms of CYP2S1 in a Finnish Caucasian population.

    CYP2S1 is a recently discovered member of the cytochrome P450 (CYP) gene superfamily. Interestingly, even though the DNA sequence identifies it as the sole member of the new CYP2S family, CYP2S1 exhibits many features typical to CYP1 family members, e.g. dioxin-inducibility mediated by the aryl hydrocarbon receptor (AHR) and the aryl hydrocarbon receptor nuclear translocator (ARNT). In addition, CYP2S1 metabolises some aromatic hydrocarbons as well as cellular substances. These characteristics, together with a wide extrahepatic tissue distribution, suggest that CYP2S1 may have an important role in both exogenous and endogenous metabolism. This is the first study characterising CYP2S1 alleles and naming them with the recommended CYP allele nomenclature. We used denaturing gradient gel electrophoresis (DGGE) and direct sequencing to investigate genetic variation of CYP2S1 in 100 male Finnish Caucasians. Those exons in which variation was found were examined in subsequent 100 subjects. The coding region of all of the nine exons, as well as a 449 bp fragment of the proximal promoter region, was analysed. This systematic investigation revealed eight single nucleotide polymorphisms (SNPs), which comprise nine different variant alleles (haplotypes), in addition to the wild-type allele. Seven of the SNPs occurred in the protein-coding areas and one in the proximal 3' untranslated region (3'UTR). Two of these sequence variations (10347C > T and 13106C > T) result in non-conservative amino acid substitutions, i.e. Arg380Cys and Pro466Leu, respectively. The respective allelic variants, CYP2S1*2 ([10347C > T]) and CYP2S1*3 (13106C > T; 13255A > G]), occurred in our study population at frequencies of 0.50 and 3.75%, respectively. The most common of the variant alleles was CYP2S1*1H (23.8%), harbouring a 13255A > G substitution located in the 3'UTR. PMID:15450424

    We compared calcium (Ca) sources and intake, as well as multivitamin/mineral supplement use between female students with nutrition/health background and those from general-student-populations. 314 participants 18–37 y, including 57 African-Americans and 54 Caucasian-Americans recruited from Nutrition and/or other Health Sciences departments (NHS), and 100 African-American and 103 Croatian women representing general-student-population (GSP), completed food frequency questionnaire assessing their usual Ca intake and supplement use. NHS populations met recommendations and consumed significantly more Ca, particularly from dairy sources, and were more likely to take supplements than GSP groups, suggesting that health education may influence Ca intake.

    2016-01-01

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences. PMID:26759415

    Caucasian black grouse (Tetrao mlokosiewiczi) is on the 'red' list of species of high conservation concern as nearest threatened (NT) and also in level (I) of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The black grouse distribution range in Iran is restricted to the Arasbaran region, Northwest of Iran, and the populations and range of this specialist bird species have been declining over the last decades. Management of forest and grassland structures is important for black grouse population survival. The main goals of this study were to monitor and quantify the landscape pattern changes in Caucasian black grouse habitat in the Arasbaran biosphere reserve in two periods of 14 years (1987-2001) and 10 years (2001-2011). For quantifying landscape pattern changes, various landscape metrics were derived by spatial analysis software FRAGSTATS 3.3, including NP (number of habitat patches), LPI (largest patch index) and TE (total edge). The results indicated that the proportion of forest decreased from 39.95 to 31.95% and the proportion of grassland decreased from 44.45 to 38.44% in the 24-year span. NP of forests increased in the first period and decreased in the second period of study. TE of dense forest at altitude above 1800 m decreased. Reduction of forest edge is an indicator of reduction in habitat availability for Caucasian black grouse which use the forest edge for living, lekking and hatching in upland. Our results provided quantitative data on habitat loss and fragmentation in the Arasbaran biosphere reserve and indicated negative impacts of the landscape structure changes on Black grouse habitat.

    Objective A cross-sectional study of mixed connective tissue disease (MCTD) was performed to determine if there were identifiable differences in the clinical expression of MCTD associated with race or ethnicity. Methods Miami, Florida, and Midwestern US (Missouri) Caucasian MCTD cohorts were studied. Clinical and laboratory features of the 2 MCTD cohorts were compared. A concurrently collected cohort of Sm-positive patients with systemic lupus erythematosus (SLE) was studied as a control. Disease activity and severity and functional status were measured. CD4+CD25high-expressing T-regulatory cells were enumerated and serum soluble L selectin was measured as biomarkers of disease activity. Results The Miami and Missouri Caucasian MCTD groups, while differing from the SLE group, were largely similar; however, gastroesophageal reflux, sclerodactyly, and malar rash were significantly more frequent in the Missouri MCTD group and alopecia was more frequent in the Miami MCTD group. Significant clinical and laboratory differences were found between the Miami MCTD and Miami SLE groups despite similar disease duration, activity, severity and functional status. Raynaud's phenomenon (RP), hand swelling, synovitis, myositis, and sclerodactyly were all significantly more common in RNP-positive MCTD versus Sm-positive SLE subjects. Conclusion Ethnic differences were observed in the frequency of end-organ involvement in the Miami MCTD versus the Missouri Caucasian MCTD groups. Clinical and laboratory features of all MCTD groups were clearly different from the SLE group, despite similar disease activity, disease severity, and functional status. Disease activity measures appeared to behave similarly as valid measures of disease activity in SLE and MCTD. PMID:18260175

    Objectives Obesity is considered to be one of the most important risk factors for obstructive sleep apnea (OSA) but less is known about the role of ethnicity in OSA. The purpose of this study was to investigate the interethnic difference of obesity-related phenotypes in OSA and to reveal the role of ethnicity in OSA. Methods We searched MEDLINE, LILACS, Scopus, and the Cochrane Library using the key words “sleep apnea,” “body mass index,” “neck circumference,” “waist circumference,” “waist to hip ratio,” etc. Inclusion criteria were adults over 18 years of age, and studies that included polysomnography, obesity-related parameters, and a clear demarcation of ethnicity in the patient population. Included studies were reviewed by 2 independent reviewers. The following information was collected for controls and OSA: number, age, gender, country, ethnicity (Asian or Caucasian), study design, apnea-hypopnea index/respiratory disturbance index, body mass index (BMI), neck circumference (NC), waist circumference (WC), and/or waist to hip ratio (WHR). Results A total of 8,312 publications were retrieved with a subsequent 19 manuscripts that met the selection criteria. A total of 2,966 patients were included for analysis. The main findings were as follows: There was no difference in BMI, WC, and WHR between patients with OSA and controls after accounting for publication bias; Patients with OSA have greater NC than controls (standard mean difference, 0.89; 95% confidence interval, 0.63 to 1.14); and There was no difference in NC between Asian and Caucasians patients (P=0.178). Conclusion OSA might not be related with BMI, WC, and WHR. Only NC demonstrated a strong association with OSA, and this finding was not different between Asians and Caucasians. PMID:26976019

    We evaluated whether African-Americans in the Osteoarthritis Initiative have a greater risk (vs. Caucasians) of poor 4-year function outcome within strata defined by gender, BMI, and waist circumference. Using WOMAC function, 20 meter walk, and chair stand performance, poor outcome was defined as moving into a worse function group or remaining in the 2 worst groups over 4 years. Logistic regression was used to evaluate the relationship between racial group and outcome within each stratum, adjusting for age, education, and income, and then further adjusting for BMI, comorbidity, depressive symptoms, physical activity, knee pain, and OA severity. In 3695 persons with or at higher risk for knee OA, higher BMI and large waist circumference were each associated with poor outcome. Among women with high BMI and among women with large waist circumference, African-Americans were at greater risk for poor outcome by every measure, adjusting for age, education, and income. From fully adjusted models, potential explanatory factors included income, comorbidity, depressive symptoms, pain, and disease severity. Findings were less consistent for men, emerging only for the 20 meter walk or chair stand outcomes, and potentially explained by age and knee pain. Among OAI women with excess body weight, African-Americans are at greater risk than Caucasians for poor 4-year outcome. Modifiable factors that may help to explain these findings in the OAI include comorbidity, depressive symptoms, and knee pain. Targeting such factors, while supporting weight loss, may help to lessen the outcome disparity between African-American and Caucasian women. PMID:22833527

  17. Association between XRCC1 polymorphism 399 G->A and glioma among Caucasians: a systematic review and meta-analysis

    PubMed Central

    2012-01-01

    Background The x-ray cross complementing group 1 gene (XRCC1) is crucial to proper repair of DNA damage such as single-strand DNA breaks. A non-synonymous polymorphism in XRCC1, 399 G → A, has been shown to reduce effectiveness of such DNA repair and has been associated with the risk of certain cancers. The known risk for glioma from high dose ionizing radiation makes associations between this polymorphism and glioma of particular interest. Methods A systematic literature review and meta-analysis was conducted to explore the association between XRCC1 399 G → A and glioma. Subgroup analyses by grade, gender, genotyping method, country in which study was conducted, and study size were conducted when data were available and validity of the results were assessed by influence analyses and exploration of potential publication bias. Results Six studies were eligible for meta-analysis including data on 2,362 Caucasian glioma cases and 3,085 Caucasian controls. Pooled analysis yielded a significant association between the variant of interest and risk of glioma (OR = 1.17, 95% CI: 1.05-1.30) which was found to be disproportionately driven by a single study. Exclusion of this study, in an influence analysis, produced no statistically significant evidence of association with glioma (OR = 1.10, 95% CI: 0.98-1.23), and no evidence of publication bias. Conclusions This meta-analysis does not suggest a major role of the XRCC1 399 G → A polymorphism in influencing risk of glioma among Caucasians. Future studies should report data separately for glioma subtypes to permit stratified analyses for Grade III and Grade IV glioma and examine other polymorphisms in this gene. PMID:23101479

    Aim The purpose of the study was to explore the perceived risk for diabetes and heart attack and associated health status of Caucasian, Filipino, Korean, and Latino Americans without diabetes. Methods A cross-sectional survey was conducted with 904 urban adults (mean age 44.3 ± 16.1 years; 64.3% female) in English, Spanish or Korean between August and December 2013. Results Perceived risk for developing diabetes was indicated by 46.5% (n = 421), and 14.3% (n = 129) perceived themselves to be at risk for having a heart attack in their lifetime. Significant predictors of pessimistic diabetes risk perceptions: Filipino (adjusted odds ratio [AOR] = 1.7; 95% CI: 1.04–2.86) and Korean (AOR = 2.4; 1.33–4.48) ethnicity, family history of diabetes (AOR = 1.4; 1.00–1.84), female gender (AOR = 1.4; 1.04–1.96), high cholesterol (AOR= 1.6; 1.09–2.37) and higher body mass index (BMI) (AOR = 1.1; 1.08–1.15). Predictors of pessimistic heart attack risk perceptions were family history of an early heart attack (AOR = 2.9; 1.69–5.02), high blood pressure (AOR = 2.4; 1.45–3.84), and higher BMI (AOR = 1.1; 1.04–1.12) after controlling for socio-demographic factors. Older age, physical inactivity, smoking, and low HDL levels were not associated with risk perceptions. Conclusion Multiple risk factors were predictive of greater perceived diabetes risk, whereas, only family history of heart attack, high blood pressure and increases in BMI significantly contributed to perceived risk of heart attack among ethnically diverse at risk middle-aged adults. It is important that healthcare providers address the discordance between an individual’s risk perceptions and the presence of actual risk factors. PMID:25931282

  19. Understanding the female offender.

    PubMed

    Cauffman, Elizabeth

    2008-01-01

    Although boys engage in more delinquent and criminal acts than do girls, female delinquency is on the rise. In 1980, boys were four times as likely as girls to be arrested; today they are only twice as likely to be arrested. In this article, Elizabeth Cauffman explores how the juvenile justice system is and should be responding to the adolescent female offender. Cauffman begins by reviewing historical trends in arrest rates, processing, and juvenile justice system experiences of female offenders. She also describes the adult outcomes commonly observed for female offenders and points out that the long-term consequences of offending for females are often more pronounced than those for males, with effects that extend to the next generation. She also considers common patterns of offending in girls, as well as factors that may increase or decrease the likelihood of offending. She then reviews what is known about effective treatment strategies for female offenders. Female delinquents have a high frequency of mental health problems, suggesting that effective prevention efforts should target the mental health needs of at-risk females before they lead to chronic behavior problems. Once girls with mental health problems come into the juvenile justice system, says Cauffman, diverting them to community-based treatment programs would not only improve their individual outcomes, but allow the juvenile justice system to focus on cases that present the greatest risk to public safety. Evidence is emerging that gender-specific treatment methods can be effective for female offenders, especially when treatment targets multiple aspects of offenders' lives, including family and peer environments. But it is also becoming clear that female offenders are not a homogeneous group and that treatment ultimately should be tailored to suit individual needs defined more specifically than by gender alone. Despite myriad differences between male and female offending, many of the primary causes of

    Pima Indians are insulin resistant and hyperinsulinaemic compared with Caucasians. We investigated whether abdominal fat distribution was different between Pimas and Caucasians and whether differences in the amount of visceral fat explained metabolic differences between the groups. Total body fat (absorptiometry) and abdominal fat distribution at L4-L5 (magnetic resonance imaging) were compared in 20 Pima Indians (10 men/10 women) and 20 age-, sex- and BMI-matched Caucasians. Insulin action was measured as glucose disposal during a two-step hyperinsulinaemic-euglycaemic glucose clamp and insulin secretion was assessed in response to oral and intravenous glucose tolerance tests. By design, percent body fat was similar in Pimas and Caucasians. Abdominal visceral and subcutaneous adipose tissue areas were also similar in the two groups (151+/-16 vs 139+/-15 cm2 and 489+/-61 vs 441+/-7 cm2 respectively). Plasma insulin concentrations were higher in Pimas than Caucasians in the fasting state (27+/-6 vs 11+/-2 mU/ml; p < 0.01) and after a 75-g oral glucose load (area under the curve 19975+/-2626 vs 9293+/-1847 mU x l(-1) x 180 min(-1); p < 0.005). Glucose disposal was lower in Pimas than Caucasians during both steps of the clamp and negatively correlated (after adjustment for percent body fat and sex) with visceral adipose tissue in Caucasians (partial r = -0.51, p = 0.03), but not in Pima Indians (r = -0.03, p = 0.92). Insulin secretion was not related to visceral fat independently of percent body fat in either group. We conclude that a relative increase in visceral fat does not explain insulin resistance and hyperinsulinaemia in Pima Indians. PMID:10027574

    The metabolism of the anticonvulsant drug mephenytoin exhibits a genetic polymorphism in humans. This polymorphism exhibits marked racial heterogeneity, with the poor metabolizer PM phenotype representing 13-23% of oriental populations, but only 2-5% of Caucasian populations. Two defective CYP2C19 alleles (CYP2C19*2 and CYP2C19*3) have been described, which account for more than 99% of Oriental poor metabolizer alleles but only approximately 87% of Caucasian poor metabolizer alleles. Therefore, additional defects presumably contribute to the poor metabolizer in Caucasians. Recent studies have found a third mutation CYP2C19*4, which accounts for approximately 3% of Caucasian poor metabolizer alleles. A fourth rare mutation (CYP2C19*5A) (C99,A991,Ile331;C1297T,Arg433-->Trp) resulting in an Arg433 to Trp substitution in the heme-binding region has been reported in a single Chinese poor metaboliser outlier belonging to the Bai ethnic group. The present study identifies a second variant allele CYP2C19*5B (C99-->T; A991-->G, Ile331-->Val; C1297-T, Arg433-->Trp in one of 37 Caucasian poor metabolizers. The frequency of the CYP2C19*5 alleles is low in Chinese (approximately 0.25% in the Bai ethnic group) and Caucasians (< 0.9%). However, these alleles contribute to the poor metabolizer phenotype in both ethnic groups and increases the sensitivity of the genetic tests for identifying defective alleles to approximately 100% in Chinese poor metabolizers and 92% in Caucasian poor metabolizers genotyped in our laboratory. The Arg433 to Trp mutation in the heme-binding region essentially abolishes activity of recombinant CYP2C19*5A toward S-mephenytoin and tolbutamide, which is consistent with the conclusion that CYP2C19*5 represents poor metabolizer alleles.

  2. Male sexual harassment alters female social behaviour towards other females.

    Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

    Human pigmentation is a polygenic quantitative trait with high heritability. Although a large number of single nucleotide polymorphisms (SNPs) have been identified in pigmentation genes, very few SNPs have been examined in relation to human pigmentary phenotypes and skin cancer risk. We evaluated the associations between 15 SNPs in 8 candidate pigmentation genes (TYR, TYRP1, OCA2, SLC24A5, SLC45A2, POMC, ASIP and ATRN) and both pigmentary phenotypes (hair color, skin color and tanning ability) and skin cancer risk in a nested case-control study of Caucasians within the Nurses' Health Study (NHS) among 218 melanoma cases, 285 squamous cell carcinoma (SCC) cases, 300 basal cell carcinoma (BCC) cases and 870 common controls. We found that the TYR Arg402Gln variant was significantly associated with skin color (p-value = 7.7 x 10(-4)) and tanning ability (p-value = 7.3 x 10(-4)); the SLC45A2 Phe374Leu variant was significantly associated with hair color (black to blonde) (p-value = 2.4 x 10(-7)), skin color (p-value = 1.1 x 10(-7)) and tanning ability (p-value = 2.5 x 10(-4)). These associations remained significant after controlling for MC1R variants. No significant associations were found between these polymorphisms and the risk of skin cancer. We observed that the TYRP1 rs1408799 and SLC45A2 1721 C>G were associated with melanoma risk (OR, 0.77; 95% CI, 0.60-0.98 and OR, 0.75; 95% CI, 0.60-0.95, respectively). The TYR Ser192Tyr was associated with SCC risk (OR, 1.23; 95% CI, 1.00-1.50). The TYR haplotype carrying only the Arg402Gln variant allele was significantly associated with SCC risk (OR, 1.35; 95% CI, 1.04-1.74). The OCA2 Arg419Gln and ASIP g.8818 A>G were associated with BCC risk (OR, 1.50; 95% CI, 1.06-2.13 and OR, 0.73; 95% CI, 0.53-1.00, respectively). The haplotype near ASIP (rs4911414[T] and rs1015362[G]) was significantly associated with fair skin color (OR, 2.28; 95% CI, 1.46-3.57) as well as the risks of melanoma (OR, 1.68; 95% CI, 1.18-2.39) and SCC

    Acne in the adult female often presents as a chronic condition that can have a considerable negative psychological, social and emotional impact on the affected individual. Estimated prevalence rates of adult female acne vary widely according to study type. Case reports and clinical examinations estimate the prevalence of clinical acne at 10-12%, while survey estimates of physiological disease states are as high as 54%. Two subtypes of adult female acne may be defined according to time of onset: 'persistent' and 'late-onset', accounting for approximately 80 and 20% of cases, respectively. Postadolescent acne is generally mild-to-moderate in severity and presents with more inflammatory lesions and fewer comedones compared to adolescent acne. Furthermore, the impact of acne on the quality of life is often greater in adult females than in younger individuals. Despite these important differences, the key principles of acne treatment in the adult female do not differ significantly from those of other age groups. However, specific characteristics relating to the adult female should be considered when selecting a treatment regimen. PMID:24280643

    This study examined racial differences in anxious youth using data from the Child/Adolescent Anxiety Multimodal Study (CAMS) [1]. Specifically, the study aims addressed whether African American (n = 44) versus Caucasian (n = 359) children varied on (1) baseline clinical characteristics, (2) treatment process variables, and (3) treatment outcomes. Participants were ages 7-17 and met DSM-IV-TR criteria for generalized anxiety disorder, social phobia, and/or separation anxiety disorder. Baseline data, as well as outcome data at 12 and 24 weeks, were obtained by independent evaluators. Weekly treatment process variables were collected by therapists. Results indicated no racial differences on baseline clinical characteristics. However, African American participants attended fewer psychotherapy and pharmacotherapy sessions, and were rated by therapists as less involved and compliant, in addition to showing lower mastery of CBT. Once these and other demographic factors were accounted for, race was not a significant predictor of response, remission, or relapse. Implications of these findings suggest African American and Caucasian youth are more similar than different with respect to the manifestations of anxiety and differences in outcomes are likely due to treatment barriers to session attendance and therapist engagement.

    Background: strategies to prevent falls often recommend regular exercise. However, 40% of over 50s in the UK report less physical activity than is recommended. Even higher rates of sedentary behaviour have been reported among South Asian older adults. Objective: to identify salient beliefs that influence uptake and adherence to exercise for fall prevention among community-dwelling Caucasian and South Asian 60–70 year olds in the UK. Methods: we undertook an ethnographic study using participant observation, 15 focus groups (n = 87; mean age = 65.7 years) and 40 individual semi-structured interviews (mean age = 64.8 years). Data analysis used framework analysis. Results: young older adults do not acknowledge their fall risk and are generally not motivated to exercise to prevent falls. Those who had fallen are more likely to acknowledge risk of future falls. Whilst many of the beliefs about falls and exercise expressed were very similar between Caucasians and South Asians, there was a tendency for South Asians to express fatalistic beliefs more often. Conclusion: fall prevention should not be the focus of strategies to increase uptake and adherence to exercise. The wider benefits of exercise, leading to an active healthy lifestyle should be encouraged. PMID:19039019

    Objective To describe weight misperception and to examine the influence of sociodemographic factors on underestimation of weight status in Caucasian, Latino, Filipino, and Korean Americans. Design Data from 886 non-pregnant adults who participated in a cross-sectional survey administered in English, Spanish, and Korean, were analyzed. The actual weight status derived from the participants’ body mass index (BMI) categories and their perceived weight status were compared. A multiple logistic regression model was used to explore if underestimation of weight status was associated with ethnicity, gender, and education level. Results Caucasians, Latinos, Filipinos, and Koreans represented 19.4%, 26.8%, 27.4%, and 26.4% of the total sample of 886. Overall, 2 in 3 participants correctly perceived their weight status, but 42% of Latinos underestimated their weight status and 22% of Koreans overestimated their weight status. Latino ethnicity, male, and low education (≤ high school) were related to greater underestimation of weight status (p < 0.05). In contrast, Korean ethnicity was related to less underestimation of weight status (p < 0.05). Conclusions Misperception of weight status should be counted in any efforts to develop a weight management intervention for Latino and Korean Americans. PMID:26118149

    Scores on the Boston Naming Test (BNT) are frequently lower for African American when compared to Caucasian adults. Although demographically-based norms can mitigate the impact of this discrepancy on the likelihood of erroneous diagnostic impressions, a growing consensus suggests that group norms do not sufficiently address or advance our understanding of the underlying psychometric and sociocultural factors that lead to between-group score discrepancies. Using item response theory and methods to detect differential item functioning (DIF), the current investigation moves beyond comparisons of the summed total score to examine whether the conditional probability of responding correctly to individual BNT items differs between African American and Caucasian adults. Participants included 670 adults age 52 and older who took part in Mayo's Older Americans and Older African Americans Normative Studies. Under a 2-parameter logistic IRT framework and after correction for the false discovery rate, 12 items where shown to demonstrate DIF. Six of these 12 items (“dominoes,” “escalator,” “muzzle,” “latch,” “tripod,” and “palette”) were also identified in additional analyses using hierarchical logistic regression models and represent the strongest evidence for race/ethnicity-based DIF. These findings afford a finer characterization of the psychometric properties of the BNT and expand our understanding of between-group performance. PMID:19570311

    Low levels of 25-hydroxy vitamin D (25(OH)D) and polymorphisms in the vitamin D receptor gene (VDR) have been found separately to increase risk of breast cancer. The aim of this study was to determine whether low 25(OH)D levels, alone and in combination with BsmI VDR genotype, increased breast cancer risk in a United Kingdom (UK) Caucasian population. Breast cancer patients (n=179) and control women (n=179) were recruited and 25(OH)D levels measured by enzyme-linked immunosorbent assay (ELISA). VDR genotype was determined by polymerase chain reaction (PCR) and restriction enzyme digest. Analysis showed that subjects with 25(OH)D levels <50 nM and the bb BsmI VDR genotype are 6.82 times more likely to have breast cancer than subjects with levels of 25(OH)D>50 nM and either the BB or Bb genotype (95% confidence interval (CI) 2.31-14.7, P<0.001). This study indicates that low levels of circulating 25(OH)D, both alone and in combination with BsmI VDR genotype, may increase risk of breast cancer in a UK Caucasian population. PMID:15911240

    We developed a novel brain atlas template to facilitate computational brain studies of Chinese subjects and populations using high quality magnetic resonance imaging (MRI) and well-validated image analysis techniques. To explore the ethnicity-based structural brain differences, we used the MRI scans of 35 Chinese male subjects (24.03+/-2.06 years) and compared them to an age-matched cohort of 35 Caucasian males (24.03+/-2.06 years). Global volumetric measures were used to identify significant group differences in the brain length, width, height and AC-PC line distance. Using the LONI BrainParser, 56 brain structures were automatically labeled and analyzed for all subjects. We identified significant ethnicity differences in brain structure volumes, suggesting that a population-specific brain atlas may be more appropriate for studies involving Chinese populations. To address this, we constructed a 3D Chinese brain atlas based on high resolution 3.0T MRI scans of 56 right-handed male Chinese volunteers (24.46+/-1.81 years). All Chinese brains were spatially normalized by using linear and nonlinear transformation via the "AIR Make Atlas" pipeline workflow within the LONI pipeline environment. This high-resolution Chinese brain atlas was compared to the ICBM152 template, which was constructed using Caucasian brains. PMID:20152910

    Although previous studies have shown that interactions between monoamine oxidase A (MAOA) genotype and childhood maltreatment predict Caucasian boys’ antisocial behavior, the generalizability of this gene-environment interaction to more diverse populations and more common parenting behaviors, such as punitive discipline in early childhood, is not clearly understood. Among 189 low-income men (44% African American, 56% Caucasian) who underwent rigorous assessments of family behavior and social context longitudinally across 20 years, those men with the low activity MAOA allele who experienced more punitive discipline at ages 1.5, 2, and 5 years showed more antisocial behavior from ages 15 through 20 years. Effects of punitive discipline on antisocial behavior differed by caregiver and age at which it occurred, suggesting sensitive periods throughout early childhood in which low MAOA activity elevated boys’ vulnerability to harsh parenting and risk for antisocial behavior. This genetic vulnerability to punitive discipline—and not just extreme, maltreatment experiences—may generalize to other male populations at risk for antisocial behavior. PMID:27014508

    Catalase is a central antioxidant enzyme constituting the primary defense against oxidative stress. In this study, we investigated whether the functional –262C/T polymorphism in the promoter of catalase gene is associated with the presence of diabetic retinopathy (DR), diabetic nephropathy (DN) and ischemic heart disease (IHD) in 520 Caucasian-Brazilians with type 2 diabetes. The –262C/T polymorphism was also examined in 100 Caucasian blood donors. Patients underwent a clinical and laboratory evaluation consisting of a questionnaire, physical examination, assessment of diabetic complications and laboratory tests. Genotype analysis was performed using the polymerase chain reaction followed by digestion with restriction enzyme. The genotype and allele frequencies of the –262C/T polymorphism in patients with type 2 diabetes were very similar to those of blood donors (T allele frequency = 0.20 and 0.18, respectively). Likewise, there were no differences in either genotype or allele frequencies between type 2 diabetic patients with or without DR, DN or IHD. Thus, our results do not support the hypothesis that the –262C/T polymorphism is related to the development of DR, DN or IHD in patients with type 2 diabetes. Further studies are necessary to elucidate the role of catalase gene polymorphisms in the pathogenesis of diabetic complications. PMID:17264407

    Fear of negative evaluation is a central component of social anxiety. The current study examines the relation between fear of negative evaluation and fears of confirming stereotypes about a social group to which one belongs among people diagnosed with social anxiety disorder. Participants (N = 94) with a primary diagnosis of social anxiety disorder who self-identified as either African American (n = 41) or Caucasian (n = 53) completed standardized self-report measures of stereotype confirmation concerns and fear of negative evaluation. Results from hierarchical logistical regression showed that stereotype confirmation concerns predicted fear of negative evaluation for both racial groups, with greater concern predicting greater fear. This association was moderated by race, B = −.24, t = −2.67, p < .01, such that stereotype confirmation concerns had a stronger association with fear of negative evaluation for Caucasians (b = .38, p < .01) than for African Americans (b = .14, p < .05). This study is the first to directly examine the relation between stereotypes and fear of negative evaluation within a socially anxious sample. Although we cannot identify the specific social group to which each participant’s stereotype confirmation concerns apply, this study provides quantitative evidence that the social context within which socially anxious individuals view themselves impacts their fear of negative evaluation and highlights the need for further research in this area.

    In order to establish how many children with seronegative spondyloarthropathy (SpA) starting with peripheral arthritis and/or enthesitis will develop ankylosing spondylitis (AS), 13 consecutive Caucasian pediatric patients, (11 with the seronegative enthesopathy and arthropathy (SEA) syndrome and 2 with isolated B27 associated peripheral arthritis or enthesitis at entry), were followed prospectively with no loss for more than 5 years. Sacroiliac joint plain films obtained at the last visit were mixed with those of 14 control subjects and read blindly. The course of SpA was self-limiting in 6 patients and recurrent in the other 7. Six patients had episodes of inflammatory cervical and/or lumbar pain during followup. However, none showed any limitation of spinal movement in the asymptomatic periods. Only one patient (9.1%) of 11 with the SEA syndrome showed bilateral sacroiliitis and met New York criteria for AS after 5 years of disease. Our results suggest that the proportion of Caucasian children with the SEA syndrome developing AS is much lower than the 75% found in a similar study on Mexican children. Lack of evaluation of all patients after 5 years, the reading of pelvic plain films without reducing observer error, and the male predominance in the Mexican study, probably in addition to ethnic or environmental factors, may account for differences.

    No study until now has examined the impact of the physical and psychological condition on voter turnout among elderly African Americans and Caucasians. Utilizing data from a national survey (Aging in the Eighties) and using multiple logistic regression, the present study examines the impact of health rating and life satisfaction as well as other socio-psychological characteristics on voting turnout among elderly Caucasian and African Americans. The results provide some empirical evidence that the pattern of election participation can be significantly influenced by the self-assessment of health and life satisfaction. For elderly Caucasians self-assessment of health is significantly related to voting behavior, whereas among elderly African Americans life satisfaction shows significant impact on turnout. Elderly African Americans who identified their personal political philosophy as "liberal" were more likely to vote, while among elderly Caucasians, those who identified their personal political philosophy as "conservative" were more likely to vote. In addition, SES, age, and organizational activity proved to have significantly independent impact on elderly Caucasian turnout, whereas among elderly African Americans, education was detected as a significant predictor.

    The recent dramatic increase in breast cancer incidence across China with progressive urbanization and economic development has signaled the urgent need for molecular and clinical detailing of breast cancer in the Chinese population. Our analyses of a unique transethnic collection of breast cancer frozen specimens from Shanghai Fudan Cancer Center (Chinese Han) profiled simultaneously with an analogous Caucasian Italian series revealed consistent transcriptomic data lacking in batch effects. The prevalence of Luminal A subtype was significantly lower in Chinese series, impacting the overall prevalence of estrogen receptor (ER)-positive disease in a large cohort of Chinese/Caucasian patients. Unsupervised and supervised comparison of gene and microRNA (miRNA) profiles of Chinese and Caucasian samples revealed extensive similarity in the comprehensive taxonomy of transcriptional elements regulating breast cancer biology. Partition of gene expression data using gene lists relevant to breast cancer as “intrinsic” and “extracellular matrix” genes identified Chinese and Caucasian subgroups with equivalent global gene and miRNA profiles. These findings indicate that in the Chinese and Caucasian groups, breast neoplasia and the surrounding stromal characteristics undergo the same differentiation and molecular processes. Transcriptional similarity across transethnic cohorts may simplify translational medicine approaches and clinical management of breast cancer patients worldwide. PMID:25787708

    The Alpine-Himalayan convergence zone (AHCZ) underwent recent transverse shortening under the effect of collisional compression. The process was accompanied by rotation of separate microplates. The Caucasian and Eastern Mediterranean regions are segments of the of the AHCZ and are characterized by intensive endogenous and exogenous geodynamic processes, which manifest themselves in occurrence of powerful (with magnitude of 8-9) earthquakes accompanied by development of secondary catastrophic processes. Large landslides, rock falls, avalanches, mud flows, etc. cause human deaths and great material losses. The development of the aforesaid endogenous processes is set forth by peculiarities of the deep structure of the region and an impact of deep geological processes. The Caucasus is divided into several main tectonic terranes: platform (sub-platform, quasi-platform) and fold-thrust units. Existing data enable to perform a division of the Caucasian region into two large-scale geological provinces: southern Tethyan and northern Tethyan located to the south of and to the north of the Lesser Caucasian ophiolite suture, respectively. The recent investigations show that the assessments of the seismic hazard in these regions are not quite correct - for example in the West Caucasus the seismic hazard can be significantly underestimated, which affects the corresponding risk assessments. Integrated analysis of gravity, magnetic, seismic and thermal data enables to refine the assessment of the seismic hazard of the region, taking into account real rates of the geodynamic movements. Important role play the last rheological constructions. According to Reilinger et al. (2006) tectonic scheme, the West flanking of the Arabian Plate manifests strike-slip motion, when the East Caucasian block is converging and shortening. The Eastern Mediterranean is a tectonically complex region located in the midst of the progressive Afro-Eurasian collision. The recent increasing geotectonic

    The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

    AIDS is spreading most rapidly among women, who often cannot negotiate the use of a male condom with reluctant partners. Recent findings from 6 countries, however, indicate that women can draw upon peer support to help them negotiate female condom use with reluctant partners. These findings come from Family Health International's (FHI) AIDS Control and Prevention (AIDSCAP) Project's introduction of the female condom to women through peer support groups in Kenya and Brazil, and the Joint UN Program on HIV/AIDS' (UNAIDS) coordinated studies in Costa Rica, Indonesia, Mexico, and Senegal on sexual negotiation, women's empowerment, and the female condom, also using group education sessions. The US Agency for International Development recently committed $100,000 toward the purchase of 150,000 female condoms for operations research and familiarization in countries where officials have not been exposed to the method. More than 130 participants from 19 countries attended FHI's May 1-2, 1997, conference on the female condom convened in Arlington, Virginia. PMID:12292734

    Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees. PMID:8400925

    The female athlete triad is a spectrum of interrelated pathophysiologic consequences of low energy availability, menstrual dysfunction, and low bone mineral density. Components of the triad are not only counterproductive to athletic performance goals, but can lead to serious long-term negative health outcomes. Practitioners caring for female athletes play an important role detecting at-risk athletes early in their course along the disease spectrum. Importantly, women who are evaluated for one component of the triad should always be screened for the other two. Detecting the disorder early is the most important factor for preventing the potentially severe consequences, and requires heightened vigilance on the part of all those who work with this special patient population. In this article, we discuss the epidemiology, pathophysiology, diagnosis, evaluation, and management of the female athlete triad. PMID:25365814

    The passage of Title IX legislation in 1972 provided enormous opportunities for women to reap the benefits of sports participation. For most female athletes, sports participation is a positive experience, providing improved physical fitness, enhanced self-esteem, and better physical and mental health. Nonetheless, for a few female athletes, the desire for athletic success combined with the pressure to achieve a prescribed body weight may lead to the development of a triad of medical disorders including disordered eating, menstrual dysfunction, and low bone mineral density (BMD)--known collectively as the female athlete triad. Alone or in combination, the disorders of the triad can have a negative impact on health and impair athletic performance. PMID:17241915

    Female pattern hair loss, or female pattern androgenetic alopecia, is a nonscarring alopecia with a multi-factorial etiology that mostly affects postmenopausal women and is characterized by a reduction in hair density over the crown and frontal scalp. The clinical picture is characterized by a diffuse rarefaction of scalp hair over the mid-frontal scalp and a more-or-less intact frontal hairline without any signs of inflammation or scarring. Although the disease poses only a cosmetic concern, it is chronic and may have a significant negative psychological impact on the affected person. The aim of treating female pattern hair loss is to reduce hair loss and, to a certain extent, succeed in promoting hair regrowth. Various treatment methods are available, but it remains unclear which are the most effective. Early initiation of treatment and the combination of various modalities seem to be more efficacious than monotherapy. PMID:26370643

    200 dental plaster casts of Western Cape Caucasoid subjects, all of whom were under the age of 21 years, were used in this study. Mesio-distal measurements (MD lengths) were obtained of all the teeth, disregarding the third molars. This data was used to develop regression equations, for maxillary and for mandibular arches, to enable the prediction of the mesio-distal lengths of the canine and two premolars. The study identified the sum of the MD lengths of the permanent lower incisors as the best predictor. It appears that separate predictions for male and female are not warranted. The equations and the predicted values were compared with those of Moyers (1973 and 1988) and some significant differences were found. The Prediction Tables will be useful in analysis of the mixed dentition phase in patients from this population group. PMID:1820683

Physical examination revealed swelling of the bilateral lower extremities. There was exquisite tenderness on palpation over the medial thighs, with marked increase in pain on hip and knee flexion. Muscle strength of quadriceps, hamstrings, and hip adductor was decreased due to muscle pain. Pedal pulses were palpable bilaterally. Roentogenograms of the left femur revealed calcification of the left femoral arterial wall. Venogram revealed no obstruction with normal drainage. Complete blood cell count showed left shift of the neutrophils, markedly accelerated erythrocyte sedimentation rate, prolonged prothorombin time of 9 sec (normal 11.7 sec), C-reactive protein of 7.3 mg/dl and serum creatine kinase level of 175 IU/L. FBS was 225 mg/dl and Hb A 1 c was 16.4%. An MR imaging of the thighs revealed high signal intensities in the bilateral adductor muscles on T 2-weighted images. The symptoms resolved spontaneously over a three week period. From the course of the illness and MR imaging, the patient was diagnosed having diabetic muscle infarction (DMI), a rare complication of diabetes mellitus. To our knowledge, this is the first reported case of DMI in Japan. Diabetic microangiopathy and hypercoagulability are thought to be responsible for inducing DMI. Because the diagnosis can be made from the characteristic clinical and the typical MR imaging findings, muscle biopsy is not always necessary to obtain the diagnosis of DMI. PMID:10391074

    Since the passage of Title IX in 1972, women's participation in physical activity and sports has increased significantly. A concurrent expansion in the body of knowledge regarding women and sports has occurred. Questions regarding menstrual dysfunction and exercise continue, while new questions about menstrual dysfunction and its effect on bone mineral density have arisen. Physical and physiological differences between men and women not only guide treatment, but help fuel policy decisions regarding competition between males and females. It is essential for the physical therapist to remain current on issues related to women and sports in order to better advise and treat the female athlete. PMID:8808516

    Female hair loss is a devastating issue for women that has only relatively recently been publicly acknowledged as a significant problem. Hair transplant surgery is extremely successful in correcting the most cosmetically problematic areas of alopecia. This article discusses the surgical technique of hair transplantation in women in detail, including pearls to reduce postoperative sequelae and planning strategies to ensure a high degree of patient satisfaction. A brief overview of some of the medical treatments found to be helpful in slowing or reversing female pattern hair loss is included, addressing the available hormonal and topical treatments.

    Recent studies have shown that participants use different eye movement strategies when scanning own- and other-race faces. However, it is unclear (1) whether this effect is related to face recognition performance, and (2) to what extent this effect is influenced by top-down or bottom-up facial information. In the present study, Chinese participants performed a face recognition task with Chinese, Caucasian, and racially ambiguous faces. For the racially ambiguous faces, we led participants to believe that they were viewing either own-race Chinese faces or other-race Caucasian faces. Results showed that (1) Chinese participants scanned the nose of the true Chinese faces more than that of the true Caucasian faces, whereas they scanned the eyes of the Caucasian faces more than those of the Chinese faces; (2) they scanned the eyes, nose, and mouth equally for the ambiguous faces in the Chinese condition compared with those in the Caucasian condition; (3) when recognizing the true Chinese target faces, but not the true target Caucasian faces, the greater the fixation proportion on the nose, the faster the participants correctly recognized these faces. The same was true when racially ambiguous face stimuli were thought to be Chinese faces. These results provide the first evidence to show that (1) visual scanning patterns of faces are related to own-race face recognition response time, and (2) it is bottom-up facial physiognomic information that mainly contributes to face scanning. However, top-down knowledge of racial categories can influence the relationship between face scanning patterns and recognition response time. PMID:25497461

    Children, 4-6 years old, 153 Caucasian and 50 African-American, from a pre-school and kindergarten programme in a low income industrial area, who participated in a voluntary oral health examination, were questioned and examined for signs and symptoms of craniomandibular disorders (CMD) and of oral parafunctions. Most of the CMD signs and symptoms were mild. Eight per cent had recurrent (at least 1-2 times per week) TMJ pain, and 5% had recurrent neck pain, African-American children more often than Caucasian children (P < 0.05). Seventeen per cent had recurrent headache. Three per cent had recurrent earache. Pain or tiredness in the jaws during chewing was reported by 25% of the children, more often by African-American than by Caucasian children (P < 0.001) and more often by girls than by boys (P < 0.05). Pain at jaw opening occurred in 10% of the children, more often in the African-American than in the Caucasian group (P < 0.001). Thirteen per cent of the children had problems in opening the mouth. Deviation during opening was observed in 17% and reduced opening in 2%. Reduced lateral movements, locking or luxation were not observed in any child. Palpation pain was found in the lateral TMJ area in 16%, in the posterior TMJ area in 25%, in the temporalis and masseter areas in 10%, and pain for all regions was found more often in the African-American than in the Caucasian children (P < 0.01). Thirty-four per cent of the African-American, and 15% of the Caucasian children admitted to having ear noises (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7722749

    Several studies have reported differences between African Americans and Caucasians in relative proportion of psychotic symptoms and disorders, but whether this reflects racial bias in the assessment of psychosis is unclear. The purpose of this study was to examine the distribution of psychotic symptoms and potential bias in symptoms assessed via semi-structured interview using a cohort of 3,389 African American and 5,692 Caucasian participants who were diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder. In this cohort, the diagnosis of schizophrenia was relatively more common, and the diagnosis of bipolar disorder and schizoaffective disorder-bipolar type was less relatively common, among African Americans than Caucasians. With regard to symptoms, relatively more African Americans than Caucasians endorsed hallucinations and delusions symptoms, and this pattern was striking among cases diagnosed with bipolar disorder and schizoaffective-bipolar disorder. In contrast, the relative endorsement of psychotic symptoms was more similar among cases diagnosed with schizophrenia and schizoaffective disorder-depressed type. Differential item function analysis revealed that African Americans with mild psychosis over-endorsed "hallucinations in any modality" and under-endorsed "widespread delusions" relative to Caucasians. Other symptoms did not show evidence of racial bias. Thus, racial bias in assessment of psychotic symptoms does not appear to explain differences in the proportion of symptoms between Caucasians and African Americans. Rather, this may reflect ascertainment bias, perhaps indicative of a disparity in access to services, or differential exposure to risk factors for psychosis by race. © 2015 Wiley Periodicals, Inc.

    Study Objectives: To evaluate vitamin D (25(OH)D) levels in obstructive sleep apnea syndrome (OSAS) and possible relationships to OSAS severity, sleepiness, lung function, nocturnal heart rate (HR), and body composition. We also aimed to compare the 25(OH)D status of a subset of OSAS patients compared to controls matched for important determinants of both OSAS and vitamin D deficiency (VDD). Methods: This was a cross-sectional study conducted at an urban, clinical sleep medicine outpatient center. We recruited newly diagnosed, Caucasian adults who had recently undergone nocturnal polysomnography. We compared body mass index (BMI), body composition (bioelectrical impedance analysis), neck circumference, sleepiness (Epworth Sleepiness Scale), lung function, and vitamin D status (serum 25-hydrpoxyvitamin D (25(OH)D) across OSAS severity categories and non-OSAS subjects. Next, using a case-control design, we compared measures of serum 25(OH)D from OSAS cases to non-OSAS controls who were matched for age, gender, skin pigmentation, sleepiness, season, and BMI. Results: 106 adults (77 male; median age = 54.5; median BMI = 34.3 kg/m2) resident in Dublin, Ireland (latitude 53°N) were recruited and categorized as non-OSAS or mild/moderate/severe OSAS. 98% of OSAS cases had insufficient 25(OH)D (< 75 nmol/L), including 72% with VDD (< 50 nmol/L). 25(OH)D levels decreased with OSAS severity (P = 0.003). 25(OH)D was inversely correlated with BMI, percent body fat, AHI, and nocturnal HR. Subsequent multivariate regression analysis revealed that 25(OH)D was independently associated with both AHI (P = 0.016) and nocturnal HR (P = 0.0419). Our separate case-control study revealed that 25(OH)D was significantly lower in OSAS cases than matched, non-OSAS subjects (P = 0.001). Conclusions: We observed widespread vitamin D deficiency and insufficiency in a Caucasian, OSAS population. There were significant, independent, inverse relationships between 25(OH)D and AHI as well as

    2013-01-01

    Background Melasma is a common hypermelanosis of the face. The use of a classical Q-switched ruby laser (QSRL) to treat melasma is discussed controversially and is associated with frequent adverse effects, such as hyper- or hypopigmentation. Recently a fractional-mode (FRx) QSRL was developed to minimize the adverse effects of classical QSRL. The objective of this research was to evaluate the efficacy and safety of a novel FRx-QSRL in the treatment of melasma in Caucasian patients. Methods We performed a retrospective study of 25 Caucasian melasma patients (Fitzpatrick skin types I to III). Patients received one to three FRx-QSRL treatments (Tattoostar FRx, Asclepion Laser Technologies, Jena, Germany) at pulse energies of 4 to 8 J/cm2. Three blinded investigators independently evaluated the melasma area and severity index (MASI) score before treatment and at the four- to six-week follow-ups. At additional three-month follow-ups, patients evaluated subjective improvement, pain and over-all satisfaction with the treatment according to a numeric analogue score (NAS). Side effects were documented. Results At four to six weeks post laser treatment for a mean of 1.4 sessions, we observed a significant (P = 0.0001) reduction of the MASI score from 6.54 to 1.98 (72.3%). Patients rated the pain of the intervention at a mean 2.46 points (0 = no pain; 10 = maximum pain), the improvement at a mean 5.55 points (0 = no improvement; 10 = maximum improvement) and the overall satisfaction at a mean 4.66 points (0 = not satisfied; 10 = maximum satisfaction). After three months, post-inflammatory hyperpigmentation (PIH) and/or recurring melasma were observed in 7 (28%) and 11 (44%) patients, respectively. Conclusion The 694-nm FRx-QSRL is a safe and effective option for treating melasma in Caucasian patients. Over periods of >3 months, PIH and/or recurring melasma may develop at significant rates and may reduce patient satisfaction. Multiple treatment

    Background Lack of reliable predictive biomarkers is a stumbling block in the management of prostate cancer (CaP). Prostate-specific antigen (PSA) widely used in clinics has several caveats as a CaP biomarker. African-American CaP patients have poor prognosis than Caucasians, and notably the serum-PSA does not perform well in this group. Further, some men with low serum-PSA remain unnoticed for CaP until they develop disease. Thus, there is a need to identify a reliable diagnostic and predictive biomarker of CaP. Here, we show that BMI1 stem-cell protein is secretory and could be explored for biomarker use in CaP patients. Methodology/Principal Findings Semi-quantitative analysis of BMI1 was performed in prostatic tissues of TRAMP (autochthonous transgenic mouse model), human CaP patients, and in cell-based models representing normal and different CaP phenotypes in African-American and Caucasian men, by employing immunohistochemistry, immunoblotting and Slot-blotting. Quantitative analysis of BMI1 and PSA were performed in blood and culture-media of siRNA-transfected and non-transfected cells by employing ELISA. BMI1 protein is (i) secreted by CaP cells, (ii) increased in the apical region of epithelial cells and stromal region in prostatic tumors, and (iii) detected in human blood. BMI1 is detectable in blood of CaP patients in an order of increasing tumor stage, exhibit a positive correlation with serum-PSA and importantly is detectable in patients which exhibit low serum-PSA. The clinical significance of BMI1 as a biomarker could be ascertained from observation that CaP cells secrete this protein in higher levels than cells representative of benign prostatic hyperplasia (BPH). Conclusions/Significance BMI1 could be developed as a dual bio-marker (serum and biopsy) for the diagnosis and prognosis of CaP in Caucasian and African-American men. Though compelling these data warrant further investigation in a cohort of African-American patients. PMID:23308129

    CYP2D6 genotyping (CYP2D6*3, CYP2D6*4, CYP2D6*5, CYP2D6*13, CYP2D6*16 alleles and gene duplications) was previously performed on 1053 Caucasian and African-American lung cancer cases and control individuals and no significant difference in allele frequencies between cases and control individuals detected. We have carried out additional genotyping (CYP2D6*6, CYP2D6*7, CYP2D6*8, CYP2D6*9, CYP2D6*10, CYP2D6*17 alleles) and debrisoquine phenotyping on subgroups from this study to assess phenotype-genotype relationships. African-Americans showed significant differences from Caucasians with respect to frequency of defective CYP2D6 alleles, particularly CYP2D6*4 and CYP2D6*5. The CYP2D6*17 allele occurred at a frequency of 0.26 among 87 African-Americans and appeared to explain higher average metabolic ratios among African-Americans compared with Caucasians. CYP2D6*6, CYP2D6*8, CYP2D6*9 and CYP2D6*10 were rare in both ethnic groups but explained approximately 40% of higher than expected metabolic ratios among extensive metabolizers. Among individuals phenotyped with debrisoquine, 32 out of 359 were in the poor metabolizer range with 24 of these (75%) also showing two defective CYP2D6 alleles. Additional single strand conformational polymorphism analysis screening of samples showing large phenotype-genotype discrepancies resulted in the detection of three novel polymorphisms. If subjects taking potentially interfering drugs were excluded, this additional screening enabled the positive identification of 88% of phenotypic poor metabolizers by genotyping. This sensitivity was comparable with that of phenotyping, which identified 90% of those with two defective alleles as poor metabolizers. PMID:9918137

    2013-01-01

    Context: Female pattern hair loss (FPHL) also known as female androgenetic alopecia is a common condition afflicting millions of women that can be cosmetically disrupting. Prompt diagnosis and treatment are essential for obtaining optimal outcome. This review addresses the clinical presentation of female pattern hair loss, its differential diagnosis and treatment modalities. Evidence Acquisition: A) Diffuse thinning of the crown region with preservation of the frontal hairline (Ludwig’s type) B) The “Christmas tree pattern” where the thinning is wider in the frontal scalp giving the alopecic area a triangular shaped figure resembling a christmas tree. C) Thinning associated with bitemporal recession (Hamilton type). Generally, FPHL is not associated with elevated androgens. Less commonly females with FPHL may have other skin or general signs of hyperandrogenism such as hirsutism, acne, irregular menses, infertility, galactorrhea and insulin resistance. The most common endocrinological abnormality associated with FPHL is polycystic ovarian syndrome (PCOS). Results: The most important diseases to consider in the differential diagnosis of FPHL include Chronic Telogen Effluvium (CTE), Permanent Alopecia after Chemotherapy (PAC), Alopecia Areata Incognito (AAI) and Frontal Fibrosing Alopecia (FFA). This review describes criteria for distinguishing these conditions from FPHL. Conclusions: The only approved treatment for FPHL, which is 2% topical Minoxidil, should be applied at the dosage of 1ml twice day for a minimum period of 12 months. This review will discuss off-label alternative modalities of treatment including 5-alfa reductase inhibitors, antiandrogens, estrogens, prostaglandin analogs, lasers, light treatments and hair transplantation.

    2012-01-01

    Context: The female athlete triad (the triad) is an interrelationship of menstrual dysfunction, low energy availability (with or without an eating disorder), and decreased bone mineral density; it is relatively common among young women participating in sports. Diagnosis and treatment of this potentially serious condition is complicated and often requires an interdisciplinary team. Evidence Acquisition: Articles from 1981 to present found on PubMed were selected for review of major components of the female athlete triad as well as strategies for diagnosis and treatment of the conditions. Results: The main goal in treatment of young female athletes with the triad is a natural return of menses as well as enhancement of bone mineral density. While no specific drug intervention has been shown to consistently improve bone mineral density in this patient population, maximizing energy availability and optimizing vitamin D and calcium intake are recommended. Conclusions: Treatment requires a multidisciplinary approach involving health care professionals as well as coaches and family members. Prevention of this condition is important to minimize complications of the female athlete triad. PMID:23016101

    Data from the measurement of broadband ultrasonic attenuation (BUA) and speed of sound (SOS), using the Lunar Achilles ultrasonic densitometer, were collected for Caucasian women from five centres in the United Kingdom (Leeds, London, Nottingham, Lincoln and Sheffield). After correcting for machine variability at each site, the data were combined into a central reference database comprising 2087 women aged 16-93 years. The data are presented in 5-year bands and show a mean fall of 0.36% per year for BUA and 0.08% per year for SOS in the 60 years following the attainment of peak bone mass. This fall in BUA compares with that observed using dual energy X-ray absorptiometry studies of the lumbar spine and femoral neck of 0.32% per year and 0.44% per year, respectively, for the age range 25-65 years.

    The biological properties of the isolate from Trichinella from ajackal in the North-Caucasian Region of the Russian Federation were studied. The jackal's muscle tissue showed two Trichinella species preserving their genetic isolation during 5 passages on mice. Oval capsules containing live larvae (on day 90 after infection) in the rat muscles corresponds to the conventional description of the species Trichinella spiralis in their morphometric and biological properties. The morphological data, biological properties, and poor adaptation of round capsule-enclosed parasites to rats indirectly show their affiliation to the other Trichinella species--T. native or T. britovi. There was a negative test for outbred albino rat muscle Trichinella resistance to freezing, which, might be associated with the poor adaptation of this Trichinella isolate to this species of rodents.

    Aspects of the female body may be attractive because they signal evolutionary fitness. Greater body fatness might reflect greater potential to survive famines, but individuals carrying larger fat stores may have poor health and lower fertility in non-famine conditions. A mathematical statistical model using epidemiological data linking fatness to fitness traits, predicted a peaked relationship between fatness and attractiveness (maximum at body mass index (BMI) = 22.8 to 24.8 depending on ethnicity and assumptions). Participants from three Caucasian populations (Austria, Lithuania and the UK), three Asian populations (China, Iran and Mauritius) and four African populations (Kenya, Morocco, Nigeria and Senegal) rated attractiveness of a series of female images varying in fatness (BMI) and waist to hip ratio (WHR). There was an inverse linear relationship between physical attractiveness and body fatness or BMI in all populations. Lower body fat was more attractive, down to at least BMI = 19. There was no peak in the relationship over the range we studied in any population. WHR was a significant independent but less important factor, which was more important (greater r2) in African populations. Predictions based on the fitness model were not supported. Raters appeared to use body fat percentage (BF%) and BMI as markers of age. The covariance of BF% and BMI with age indicates that the role of body fatness alone, as a marker of attractiveness, has been overestimated. PMID:26336638

    Associations of parity with body fat and its distribution are poorly understood; therefore, we examined the relationships between parity and obesity in young adult women. Body mass index (BMI), skin-folds, and waist-hip ratio were compared in 1452 African-American and 1268 Caucasian nonpregnant women aged 18 to 30, adjusting for age (where no age-parity interactions were present), education, physical activity (assessed by questionnaire) and fitness (assessed by graded exercise test), dietary fat intake, alcohol and smoking. Adjusted mean BMI was significantly higher in African-American women aged 25-30 years with three or more children (28.5 kg/m2) than in those with two (27.0 kg/m2), one (26.2 kg/m2), or no children (26.3 kg/m2). Similar trends were found in Caucasians (BMI = 23.3, 23.4, 23.7, 25.0 kg/m2 for parity = 0, 1, 2, > or = 3, respectively), but the mean BMI was significantly higher in African Americans in each parity group. The association between BMI and parity was not present among women 18-24 years of age. Skinfolds were directly associated with parity in African Americans only. Waist-hip ratios were generally lower among nulliparous than parous women in both ethnic groups; race differences were present only among nulliparas. In conclusion, parity was associated with BMI in women aged 25 to 30 years but did not explain ethnicity-related differences in body mass. PMID:16358400

    Neuromyelitis optica (NMO) is a homogenous disease that can be diagnosed by an association of clinical, neuroimaging and serological aspects. We analysed our 4 years NMO series with longitudinally extensive transverse myelitis (LETM) during the disease course. We included consecutive adult Caucasian patients who were diagnosed with definite NMO, or cases of NMO-IgG seropositive LETM considered as limited forms of NMO. Patients included were negative for other diseases (autoimmune, infectious, etc.). We report the Expanded Disability Status Scale (EDSS), brain and spine MRI, CSF, NMO-IgG, treatment, motor and visual outcome. Thirteen cases fulfilled the inclusion criteria, and the mean follow-up period was 3.74 ± 1.8 years. The initial motor deficit was severe with the mean value of motor functional parameter of 4.46 ± 1 and improved at discharge to 2.53 ± 1.4 (p < 0.001). With treatment, the outcome after LETM attack was good in 10 patients, with a significant improvement of the EDSS mainly upon motor deficit, while visual function had a very slight amelioration. The CSF analysis was normal in 8 cases; spinal MRI showed evidence of LETM in all patients while brain MRI was normal in 7. NMO-IgG is a biomarker for NMO that is of diagnostic value in cases of isolated LETM. LETM has a better outcome than ON in NMO Caucasians. Spinal MRI is essential for NMO diagnosis in the presence of LETM and the absence of multiple brain MRI lesions. Maintenance immunosuppressive therapy reduces the frequency of attacks. PMID:25944511

    Background Klotho has an important role in insulin signalling and the development of ageing-like phenotypes in mice. The common functional "KL-VS" variant in the KLOTHO (KL) gene is associated with longevity in humans but its role in type 2 diabetes is not known. We performed a large case-control and family-based study to test the hypothesis that KL-VS is associated with type 2 diabetes in a UK Caucasian population. Methods We genotyped 1793 cases, 1619 controls and 1616 subjects from 509 families for the single nucleotide polymorphism (SNP) F352V (rs9536314) that defines the KL-VS variant. Allele and genotype frequencies were compared between cases and controls. Family-based analysis was used to test for over- or under-transmission of V352 to affected offspring. Results Despite good power to detect odds ratios of 1.2, there were no significant associations between alleles or genotypes and type 2 diabetes (V352 allele: odds ratio = 0.96 (0.84–1.09)). Additional analysis of quantitative trait data in 1177 healthy control subjects showed no association of the variant with fasting insulin, glucose, triglycerides, HDL- or LDL-cholesterol (all P > 0.05). However, the HDL-cholesterol levels observed across the genotype groups showed a similar, but non-significant, pattern to previously reported data. Conclusion This is the first large-scale study to examine the association between common functional variation in KL and type 2 diabetes risk. We have found no evidence that the functional KL-VS variant is a risk factor for type 2 diabetes in a large UK Caucasian case-control and family-based study. PMID:16753056

    This study's primary purpose was to examine the relative contribution of social-behavioral predictors to reading and math skills. The study expands on Duncan et al.'s (2007) work by using longitudinal methodology from the National Institute of Child Health and Human Development's Study of Child Care and Youth Development (SECCYD) and the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) databases, and by focusing on potential differences in patterns of early predictors of later reading and math trajectories for African American versus Caucasian students. Predictor measures were selected at kindergarten, and the outcomes included standardized reading and math scores obtained from Grades 1, 3, 5, and 9 for the SECCYD sample, and Grades 3, 5, and 8 for the ECLS-K sample. Consistent with Duncan et al.'s findings, results reflect the relative contributions of early reading and math skills to later functioning in these respective academic domains for both samples, and there are indications for the importance of early expressive language skills to both reading and math in the SECCYD sample. Findings related to the power of social-behavioral predictors, however, are not consistent across samples. Although the SECCYD sample evidenced no such predictors, several interactions in the ECLS-K sample suggested the moderating effects of early ratings of aggressive behaviors and internalizing behaviors on later reading and math for African American students. The moderating effects of early teacher ratings of attention and internalizing behaviors for African American students as compared with Caucasian students in later math growth also were noted. The importance of early social-behavioral functions as related to later academic skills remains an important area of inquiry. PMID:20822220

    How African American hair fragility relates to hair care practices and biologic differences between races is not well understood. To assess the differences between perceptions of hair health, hair care practices, and several biologic hair parameters between Caucasian and African American women. A questionnaire on perceptions of hair health and hair care practices was administered. Biological and structural parameters of hair shaft and scalp, including growth, density, diameter, cycle, breakage, and scalp blood flow were also assessed in this case-control study. Significant differences between the Caucasian and African American women were observed in the questionnaire and biologic study data. Regarding self-reported perceptions of hair health, there were differences in the following: hair shaft type (P < 0.001), hair breakage (P = 0.040), and desire to change hair (P = 0.001). Regarding self-reported hair care practices, there were differences in the following: location of haircutting (P = 0.002) and washing (P = 0.010), washing frequency (P < 0.001), chemical relaxer use (P < 0.001), hooded hair dryer use (P < 0.001), and hair shaft conditioner use (P = 0.005). The two groups had similar practices in regard to the use of hair color, frequency of hair color use, chemical curling agents, and handheld blow dryer use. Regarding biological and structural parameters, there were differences in the following: hair growth rate (P < 0.001), density (P = 0.0016), diameter (P = 0.01), number of broken hairs (P < 0.001), and blood flow (P = 0.03). There was no significant difference in hair cycle parameters.The differences in hair care practices and hair fiber morphology among African American women may contribute to clinically observed variation in hair fragility and growth.

    We comprehensively examined the rare variants in the IPO11-HTR1A region to explore their roles in neuropsychiatric disorders. Five hundred seventy-three to 1,181 rare SNPs in subjects of European descent and 1,234-2,529 SNPs in subjects of African descent (0 < minor allele frequency (MAF) < 0.05) were analyzed in a total of 49,268 subjects in 21 independent cohorts with 11 different neuropsychiatric disorders. Associations between rare variant constellations and diseases and associations between individual rare variants and diseases were tested. RNA expression changes of this region were also explored. We identified a rare variant constellation across the entire IPO11-HTR1A region that was associated with attention deficit hyperactivity disorder (ADHD) in Caucasians (T5: P = 7.9 × 10(-31) ; Fp: P = 1.3 × 10(-32) ), but not with any other disorder examined; association signals mainly came from IPO11 (T5: P = 3.6 × 10(-10) ; Fp: P = 3.2 × 1 0(-10) ) and the intergenic region between IPO11 and HTR1A (T5: P = 4.1 × 10(-30) ; Fp: P = 5.4 × 10(-32) ). One association between ADHD and an intergenic rare variant, i.e., rs10042956, exhibited region- and cohort-wide significance (P = 5.2 × 10(-6) ) and survived correction for false discovery rate (q = 0.006). Cis-eQTL analysis showed that, 29 among the 41 SNPs within or around IPO11 had replicable significant regulatory effects on IPO11 exon expression (1.5 × 10(-17) ≤P < 0.002) in human brain or peripheral blood mononuclear cell tissues. We concluded that IPO11-HTR1A was a significant risk gene region for ADHD in Caucasians. PMID:26079129

    Unisexual all-female lizards of the genus Darevskia that are well adapted to various habitats are known to reproduce normally by true parthenogenesis. Although they consist of unisexual lineages and lack effective genetic recombination, they are characterized by some level of genetic polymorphism. To reveal the mutational contribution to overall genetic variability, the most straightforward and conclusive way is the direct detection of mutation events in pedigree genotyping. Earlier we selected from genomic library of D. unisexualis two polymorphic microsatellite containg loci Du281 and Du215. In this study, these two loci were analyzed to detect possible de novo mutations in 168 parthenogenetic offspring of 49 D. unisexualis mothers and in 147 offspring of 50 D. armeniaca mothers . No mutant alleles were detected in D. armeniaca offspring at both loci, and in D. unisexualis offspring at the Du215 locus. There were a total of seven mutational events in the germ lines of four of the 49 D. unisexualis mothers at the Du281 locus, yielding the mutation rate of 0.1428 events per germ line tissue. Sequencing of the mutant alleles has shown that most mutations occur via deletion or insertion of single microsatellite repeat being identical in all offspring of the family. This indicates that such mutations emerge at the early stages of embryogenesis. In this study we characterized single highly unstable (GATA)n containing locus in parthenogenetic lizard species D. unisexualis. Besides, we characterized various types of mutant alleles of this locus found in the D. unisexualis offspring of the first generation. Our data has shown that microsatellite mutations at highly unstable loci can make a significant contribution to population variability of parthenogenetic lizards. PMID:18648496

    Within the human MHC region larger stretches of conserved DNA, called conserved ancestral haplotypes exist. However, many MHC haplotypes contain only fragments of an ancestral haplotype. Little is known, however, on relative distribution of the ancestral haplotypes to their fragments. Therefore we determined the frequency of carriers of the whole ancestral haplotype 8.1 (AH8.1) and its fragments in 127 healthy Hungarian people, 101 healthy Ohioian females, and in nine Hungarian families. The HLA-DQ2, HLA-DR3(17), RAGE -429C allele, the mono-S-C4B genotype, the HSP70-2 1267G allele and the TNF -308A (TNF2) allele were used as markers of the AH8.1. Frequency of carriers of the whole AH8.1 and its fragments was similar in the both populations. 18% of the subjects carried the whole AH8.1 in at least one chromosome, while 17-20%, 36-39%, and 24-29%, respectively carried two or three constituents of the haplotype, only one constituent or none of them. Similar results were obtained in the family study. In addition, marked differences were found in the relationship of the constituents' alleles to the whole AH8.1. In both populations, 29%, 50-59%, 52-56% and 76-96%, respectively of the carriers of HSP70-2 1267G, RAGE-429C, TNF2, and mono-S carriers carried the whole 8.1 haplotype. These findings may have important implications for studies of the disease associations with different MHC ancestral haplotypes. PMID:17558713

    A recent survey by the Inter-African Committee for Traditional Practices Affecting the Health of Women and Children found that 75-85 million women in Africa have undergone some form of female genital mutilation (FGM). FGM has long been practiced in Kenya. The ethnic groups which practice it, including the Kikuyu, Kamba, Kisii, Kalenjin, Maasai, and people of Somali origin, have a death rate of 170/1000 of their female populations. Approximately half of these deaths are the result of FGM, a practice which also contributes to the poor health of mutilated women. The adverse health consequences of FGM have led Kenya's President Daniel arap Moi to ban the practice in his country. In announcing the ban, President Moi advised Kenyans to discontinue cultural practices and customs which have no place in modern society and which will otherwise retard development. A number of prominent Kenyans have come forth in support of Moi's move. PMID:12293761

    Abstract Modest or even occasional nonadherence to combined antiretroviral therapy (cART) can result in adverse clinical outcomes. African Americans demonstrate lower rates of adherence than Caucasians or Latinos. Identifying factors that influence medication adherence among African Americans is a critical step toward reducing HIV/AIDS disease progression and mortality. In a sample of 181 African American (n=144) and Caucasian (n=37) HIV-positive drug-using individuals [age (M=42.31; SD=6.6) education (M=13.41; SD=2.1)], we examined the influence of baseline drug use, literacy, neurocognition, depression, treatment-specific social support, and patient satisfaction with health care provider on medication adherence averaged over the course of 6 months (study dates 2002–2006). Our findings suggest differential baseline predictors of medication adherence for African Americans and Caucasians, such that patient satisfaction with provider was the strongest predictor of follow-up medication adherence for African Americans whereas for Caucasians depressive symptoms and treatment-specific social support were predictive of medication adherence (after controlling for duration of drug use).

    This study aims to (a) examine the roles of knowledge, distrust in medical professionals, information sources, and 2 dimensions of religiosity (i.e., religious activity and religious belief) in influencing willingness to participate (WTP) in cancer clinical trials and to (b) compare the results for Caucasians and African Americans in order to inform future recruitment. An online survey was fielded via a Knowledge Networks panel with a nationally representative sample including 478 Caucasians and 173 African Americans. The results showed that distrust in medical professionals was a strong barrier to WTP for both ethnic groups, whereas factual knowledge about trial procedures was not associated with WTP for either ethnic group. Seeking trial information from doctors was positively associated with WTP for Caucasians; seeking trial information from hospitals was positively associated with WTP for African Americans. More interestingly, levels of religious activity negatively predicted WTP for Caucasians but positively predicted WTP for African Americans. Self-reported religious belief was not associated with WTP for either ethnic group. In sum, although distrust is a common barrier to WTP, the influence of preferred information sources and religious activity on WTP varies as a function of ethnicity. PMID:27175604

    The risk of acute graft-versus-host disease (GVHD) after HLA-matched sibling bone marrow transplantation (BMT) is lower in Japanese than in Caucasian patients. However, race may have differential effect on GVHD dependent on the graft source. North American Caucasian and Japanese patients receiving their first allogeneic BMT or peripheral blood stem cell transplantation from an HLA-matched sibling for leukemia were eligible. BMT was performed in 13% of the Caucasian patients and in 53% of the Japanese patients. On multivariate analysis, the interaction term between race and graft source was not significant in any of the models, indicating that graft source does not affect the impact of race on outcomes. The risk of grade III or IV acute GVHD was significantly lower in the Japanese patients compared with the Caucasian patients (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.57 to 0.96), which resulted in lower risk of nonrelapse mortality in the Japanese patients (HR, 0.69; 95% CI, 0.54 to 0.89). The risk of relapse was also lower in this group. The lower risks of nonrelapse mortality and relapse resulted in lower overall mortality rates among the Japanese patients. In conclusion, our data indicate that irrespective of graft source, the risk of severe acute GVHD is lower in Japanese patients, resulting in a lower risk of nonrelapse mortality. PMID:26762681

    Exposure to idealized media portrayals of women induces appearance dissatisfaction in females, in the short term. Interventions that highlight the artificial nature of media portrayals can mitigate this effect. The present research investigated whether a 75 second television commercial, that demonstrates behind-the-scenes techniques used to artificially enhance media models, could be similarly effective. Eighty-seven Caucasian female undergraduates were randomly assigned to one of three conditions. The first group viewed music videos and ordinary television commercials. A second group viewed the same music videos and the "intervention" commercial. A final, control, group viewed television and commercials featuring no people. Viewing music videos resulted in significantly lower levels of self-reported appearance satisfaction compared to viewing control television, p<.05, d=-.67. However, exposure to the intervention commercial counter-acted this effect. Demonstrating the extent to which media portrayals of women are artificially enhanced can mitigate detrimental effects on female appearance satisfaction. PMID:21353655

    Background Polycystic ovary syndrome (PCOS) is the most common chronic endocrine disorder affecting women of reproductive age. This study aimed to compare the HRQoL of South Asian and white Caucasian women with PCOS, given that it is particularly common among women of South Asian origin and they have been shown to have more severe symptoms. Methods The Polycystic Ovary Syndrome Questionnaire (PCOSQ) and the Short Form-36 (SF-36) were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS. Results Although HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3), indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01). On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p = 0.01). The best

    Exfoliation syndrome (XFS) is an important risk factor for glaucoma (XFG) worldwide. LOXL1 variants are highly associated with XFS in most populations; however, the high frequency of risk alleles in normal individuals and the reversal of risk alleles in different ethnic populations suggest that other factors contribute to XFS pathogenesis. Clusterin (CLU) is an extracellular matrix chaperone that prevents protein aggregation and is highly expressed in ocular tissues affected by XFS. Studies examining common CLU variants for association with XFS have been inconsistent. The purpose of this study was to evaluate CLU variants for association with XFS in two independent datasets from the United States (222 cases and 344 controls) and Israel (92 cases and 102 controls). Seven tag SNPs that captured >95% of alleles at r(2) greater than 0.8 across the CLU genomic region were genotyped using TaqMan assays. Genotypes for an additional SNP, rs2279590, were imputed using phased haplotypes of HapMap reference CEU samples. Of the 8 CLU SNPs selected for the study, none were significantly associated with XFS in either case-control group (age and sex adjusted P > 0.14 and 0.36, respectively, in the US and Israeli datasets), or when they were meta-analyzed together (age and sex adjusted P > 0.13). Haplotype analysis using all 8 SNPs or only the promoter region SNPs also did not show significant associations of CLU with XFS in the combined US and Israeli dataset (P > 0.28). Meta-analysis of the data from this study and previous studies in Caucasian populations (1184 cases and 978 controls) resulted in statistically significant association of rs2279590 with XFS (summary OR = 1.18, 95% CI: 1.03-1.33, P = 0.01). Significant association between rs2279590 and XFS was also found in Indian populations (summary OR = 0.76, 95% CI: 0.61-0.96; P = 0.02); however, significant heterogeneity between the Caucasian and Indian populations possibly due to reversal of the risk allele

In male-to-female transsexuals with strong masculine facial features, facial feminization surgery is performed as part of the gender reassignment. A strong association between femininity and attractiveness has been attributed to the upper third of the face and the interplay of the glabellar prominence of the forehead. Studies have shown that a certain lower jaw shape is characteristic of males with special attention to the strong square mandibular angle and chin and also suggest that the attractive female jaw is smaller with a more round shape mandibular angles and a pointy chin. Other studies have shown that feminization of the forehead through cranioplasty have the most significant impact in determining the gender of a patient. Facial feminization surgeries are procedures aimed to change the features of the male face to that of a female face. These include contouring of the forehead, brow lift, mandible angle reduction, genioplasty, rhinoplasty and a variety of soft tissue adjustments. In our maxillofacial surgery department at the Sheba Medical Center we perform forehead reshaping combining with brow lift and at the same surgery, mandibular and chin reshaping to match the remodeled upper third of the face. The forehead reshaping is done by cranioplasty with additional reduction of the glabella area by burring of the frontal bone. After reducing the frontal bossing around the superior orbital rims we manage the soft tissue to achieve the brow lift. The mandibular reshaping, is performed by intraoral approach and include contouring of the angles by osteotomy for a more round shape (rather than the manly square shape angles), as well as reshaping of the bone in the chin area in order to make it more pointy, by removing the lateral parts of the chin and in some cases performing also genioplasty reduction by AP osteotomy.

    OBJECTIVE: To estimate the prevalence of female sexual dysfunction symptoms and the associated risk factors in a sample of patients with substance-related disorders admitted to a specialized in-patient care unit. METHODS: This study used a cross-section design, with eight months of data collection, conducted with substance-dependent women using structured questionnaires to collect socio-demographic data and identify their drug of choice. The Drug Abuse Screening Test, Short Alcohol Dependence Data questionnaire, Fagerström Test for Nicotine Dependence, and Arizona Sexual Experience Scale were also administered. RESULTS: The sample consisted of 105 women who had a mean age of 34.8 years (SD = 12.1, range = 18-65) and were predominantly heterosexual (74.3%), single (47.6%), Caucasian (50.5%), catholic (36.2%), and educated only to the level of primary education (40%), with a monthly family income of up to one minimum salary (37.5%). In 42.9% of the patients, crack was the drug of choice; 47.6% of the sample qualified for the Drug Abuse Screening Test (substantial problems related to drugs), 43.8% exhibited Short Alcohol Dependence Data (moderate or severe dependency), 47.6% exhibited Fagerström Test for Nicotine Dependence (high or very high nicotine dependence). The prevalence of sexual dysfunction symptoms was 34.2% (95% CI = [25.3, 44.1]), and a high level of nicotine dependence and low income increased the chances of having sexual dysfunction by 2.72-fold and 2.54 fold, respectively. An association was also observed between female sexual dysfunction symptoms and schooling and levels of drug dependence. CONCLUSIONS: Female sexual dysfunction symptoms were common among this sample and primarily associated with high levels of nicotine use. PMID:23525317

    Tumor necrosis factor-alpha (TNF-α) inhibitors including etanercept have been demonstrated to be very effective in severe ankylosing spondylitis (AS) in Caucasian patients. However, clinical efficacy of etanercept to treat active AS in Chinese patients has not been reported. In this study, a prospective, open-label trial of etanercept (25 mg BIW), involving 46 AS patients from 16 medical centers of Taiwan, was conducted. Questionnaire was utilized to record demographic data and clinical parameters, including Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Global Index (BASGI), Assessment in Ankylosing Spondylitis (ASAS) 20, 50, and 70, and others, before and at different time intervals after etanercept treatment. Laboratory tests including blood chemistry, hematology, urine analysis, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were done at baseline and at weeks 4, 8, and 12. In this 12-week study, etanercept demonstrated rapid and significant improvement in the ASAS20 response criteria (91.3%), at as early as 2 weeks of therapy (71.3%). Partial remission of AS was achieved in 49.3% of patients after 12 weeks of treatment. Disease activity (BASDAI) and function (BASFI) were also significantly improved after 12 weeks etanercept treatment (p < 0.0001 and p < 0.0001, respectively). In addition, significant increase of chest expansion (2.77 ± 1.69 cm versus 3.56 ± 1.82 cm, p = 0.0004) and lumbar flexion (2.11 ± 2.76 cm versus 2.58 ± 3.42 cm, p = 0.0075) and significant reduction of occiput-to-wall distance (6.59 ± 7.14 cm versus 5.32 ± 6.65 cm, p = 0.0006) were also demonstrated. Both ESR and CRP declined significantly after patients were treated with etanercept. There were no severe adverse effects during the treatment period. Etanercept is generally safe, well tolerated, and effective in Chinese patients with severe AS. Clinical efficacy, including partial remission and BASDAI, is even better in Chinese

  19. Phenotype and frequency of STUB1 mutations: next-generation screenings in Caucasian ataxia and spastic paraplegia cohorts

    PubMed Central

    2014-01-01

    Background Mutations in the gene STUB1, encoding the protein CHIP (C-terminus of HSC70-interacting protein), have recently been suggested as a cause of recessive ataxia based on the findings in few Chinese families. Here we aimed to investigate the phenotypic and genotypic spectrum of STUB1 mutations, and to assess their frequency in different Caucasian disease cohorts. Methods 300 subjects with degenerative ataxia (n = 167) or spastic paraplegia (n = 133) were screened for STUB1 variants by whole-exome-sequencing (n = 204) or shotgun-fragment-library-sequencing (n = 96). To control for the specificity of STUB1 variants, we screened an additional 1707 exomes from 891 index families with other neurological diseases. Results We identified 3 ataxia patients (3/167 = 1.8%) with 4 novel missense mutations in STUB1, including 3 mutations in its tetratricopeptide-repeat domain. All patients showed evidence of pyramidal tract damage. Cognitive impairment was present only in one and hypogonadism in none of them. Ataxia did not start before age 48 years in one subject. No recessive STUB1 variants were identified in families with other neurological diseases, demonstrating that STUB1 variants are not simply rare polymorphisms ubiquitous in neurodegenerative disease. Conclusions STUB1-disease occurs also in Caucasian ataxia populations (1.8%). Our results expand the genotypic spectrum of STUB1-disease, showing that pathogenic mutations affect also the tetratricopeptide-repeat domain, thus providing clinical evidence for the functional importance of this domain. Moreover, they further delineate the phenotypic core features of STUB1-ataxia. Pyramidal tract damage is a common accompanying feature and can include lower limb spasticity, thus adding STUB1-ataxia to the differential diagnosis of “spastic ataxias”. However, STUB1 is rare in subjects with predominant spastic paraplegia (0/133). In contrast to previous reports, STUB1-ataxia can start even above age 40

    Aims Acute lymphoblastic leukemia (ALL) is the most common of all paediatric cancers. Aside from predisposing to ALL, polymorphisms could also be associated with poor outcome. Indeed, genetic variations involved in drug metabolism could, at least partially, be responsible for heterogeneous responses to standardized leukemia treatments, hence requiring more personalized therapy. The aims of this study were to (a) to determine the prevalence of seven common genetic polymorphisms including those that affect the folate and/or thiopurine metabolic pathways, i.e. cyclin D1 (CCND1-G870A), γ-glutamyl hydrolase (GGH-C452T), methylenetetrahydrofolate reductase (MTHFR-C677T and MTHFR-A1298C), thymidylate synthase promoter (TYMS-TSER), thiopurine methyltransferase (TPMT*3A and TPMT*3C) and inosine triphosphate pyrophosphatase (ITPA-C94A), in Caucasian (n = 94, age < 20) and Vietnamese (n = 141, age < 16 years) childhood ALL and (b) to assess the impact of a multilocus genetic risk score (MGRS) on relapse-free survival (RFS) using a Cox proportional-hazards regression model. Results The prevalence of MTHFR-677TT genotype was significantly higher in Caucasians (P = 0.008), in contrast to the prevalence of TYMS-TSER*3R/3R and ITPA-94AA/AC genotypes which were significantly higher in Vietnamese (P < 0.001 and P = 0.02, respectively). Compared with children with a low MGRS (≤3), those with a high MGRS (≥4) were 2.06 (95% CI = 1.01, 4.22; P = 0.04) times more likely to relapse. Adding MGRS into a multivariate Cox regression model with race/ethnicity and four clinical variables improved the predictive accuracy of the model (AUC from 0.682 to 0.709 at 24 months). Conclusion Including MGRS into a clinical model improved the predictive accuracy of short and medium term prognosis, hence confirming the association between well determined pharmacogenotypes and outcome of paediatric ALL. Whether variants on other genes associated with folate metabolism can substantially improve the

    The comparison of psychosocial needs across different cultural settings can identify cultural and service impacts on psychosocial outcomes. We compare psychosocial needs in Hong Kong Chinese and German Caucasian women with breast cancer. Completed questionnaires were collected from 348 Chinese and 292 German women with breast cancer for assessing unmet psychosocial needs (Supportive Care Needs Survey Short Form), psychological distress (the Hospital Anxiety and Depression scale), and listed physical and psychological symptoms. Only 11% of the participants reported not needing help for any of the 34 items. More German (14%) than Chinese women (8%) reported no unmet needs (χ(2) = 6.16, P = .013). With both samples combined, the Health System and Information domain unmet needs were the most prevalent, apart from one Psychological need domain item, "Fear about the cancer spreading." Chinese and German samples differed significantly in prevalence and patterns of unmet psychosocial needs. Multivariate adjustment for demographic, clinical, and sample characteristics, psychological distress, and symptoms showed that significantly greater unmet Health system and Information, and Patient care and support domain needs, associated with the presence of symptoms (β = .232, P < .001), high HADS Anxiety (β = .187, P < .001), higher education attainment (β = .120, P = .002), and Chinese sample membership (β = .280, P < .001). Greater unmet Psychological, Physical and Daily Living, and Sexuality domain needs were associated with the presence of symptoms, psychological distress, and German group membership, among others. German women reported more anxiety (t = 10.45, P < .001) and depression (t = 3.71, P < .001). In post hoc analyses, German, but not Chinese women reporting greater anxiety and depression had greater unmet Psychological and Sexuality domain needs (P < .001). It can be concluded that culture-specific differences in supportive care needs exist. Hong Kong Chinese

    Participation of adolescents and young women in strenuous sports activity may lead to various metabolic and psychological derangements of clinical relevance to the endocrinologist. The most common manifestations encountered in practice are primary and secondary amenorrhea, reduced bone mineral density and eating disorders. The occurrence of all three together has been named "the athletic triad". The underlying hormonal drivers that lead to some of these manifestations are the reduced leptin level as well as the persistent low grade stress response commonly observed in such females. "Exercise-related female reproductive dysfunction" (ERFRD), can possibly include short-term (infertility) and long-term (osteoporosis) consequences. Functional hypothalamic amenorrhea, a manifestation of ERFRD in adolescence, is an integrated response to the combination of excessive physical and emotional stress, exercise, and/or reduced food intake characterized by decreased endogenous GNRH secretion. The primary aim of treating these athletes should be the prevention of the development of any component of the triad as well as the whole complex by educating athletes, trainers, parents and health care professionals about proper nutrition and safe training. The long term prognosis is good. However, significant long term morbidity may affect these young women later in life. PMID:20118893

    Facial, olfactory, and vocal cues may advertise women's fertility. However, most of the evidence for this proposal has come from studies of changes in young adult women's attractiveness over the menstrual cycle. By contrast with this emphasis on changes in attractiveness over the menstrual cycle, possible changes in women's attractiveness over their lifespan have received little attention. The present study investigated men's ratings of young girls' (11-15 years old), adult women's (19-30 years old) and circum-menopausal women's (50-65 years old) facial, body odor, and vocal attractiveness and femininity. Faces and voices, but not body odors, of young girls and adult women were perceived to be significantly more attractive and feminine than those of circum-menopausal women. These data suggest that facial and vocal cues may be cues to women's reproductive value, but that body odor cues do not necessarily advertise this information. PMID:23728193

    Parkinson's disease (PD) is a complex neurodegenerative disease, its etiology is largely unknown. Studies demonstrate the association of genetic and environment factors in causing neuronal degeneration. Reports suggest that the multi-drug resistance gene (MDR1) plays a vital role in preventing the toxic substance in entering the brain, which is associated with PD. However, the association between the MDR1 polymorphisms (C1236T and C3435T) and its susceptibility to PD is inconclusive. Meta analysis was carried by retrieving literatures from databases to search the case-control studies on the associations between the MRD1 polymorphisms and PD. The pooled odds ratios (ORs) and its 95% confidence intervals (CIs) were calculated using fixed and random model to determine the association between the polymorphisms and PD susceptibility. Significant association was noticed for C1236T polymorphism and PD risk in the recessive model OR=0.80, 95% CI=0.66-0.97. Further, ethnicity based analysis showed significant association for C1236T in allelic model of Asian population and also in the recessive models of both Asian and Caucasian populations. However, insignificant associations were noticed for C3435T in all the four models. Overall, the analysis suggested that MDR1 C1236T polymorphism substantially contribute to Parkinson's disease in the recessive genetic model. PMID:27538645

    Muscle phosphoglycerate mutase (PGAM) deficiency has been so far identified in only six patients, five of these being African Americans. We report the results of clinical, morphological, biochemical, muscle culture and 31P-MR spectroscopy studies in the first Caucasian patient with muscle PGAM deficiency. A 23-year-old man had a 10-year history of cramps after physical exertion with one episode of pigmenturia. Neurological examination and EMG study were normal. ECG and echocardiography revealed hypertrophy of the interventricular septum and slight dilation of the left chambers of the heart. Muscle biopsy revealed increased glycogen content and some accumulation of mitochondria. Muscle PGAM activity was markedly decreased (6.5% and 9.7% of control value in two different biopsies). Citrate synthase and other mitochondrial respiratory chain enzyme activities were much higher than normal. In contrast to the marked decrease of PGAM activity observed in muscle biopsy, total enzyme activity in the patient's aneural muscle culture was normal, being represented exclusively by BB isoenzyme. The deficiency of PGAM-MM isoenzyme was reproduced in the patient's innervated muscle culture. Muscle 31P-MR spectroscopy showed accumulation of phosphomonoesters only on fast "glycolytic" exercise. On "aerobic" exercise, Vmax, calculated from the work-energy cost transfer function, showed an increase consistent with the morphological and biochemical evidence of mitochondrial proliferation. This might represent a sort of compensatory aerobic effort in an attempt to restore muscle power. PMID:8006681

    Vitamin D plays a central role in cellular proliferation, apoptosis induction, and tumor growth suppression. The vitamin D receptor (VDR) is a crucial mediator for the cellular effects of vitamin D. A series of epidemiological studies have examined the association between the VDR FokI polymorphism and breast cancer risk, but the findings remain inconclusive. Fifteen eligible case-control studies involving 15,681 cancer cases and 20,632 control subjects were identified through searching PubMed, Embase, and Web of Science. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the association. Heterogeneity across studies was examined with the chi-square-based Q test and the I (2) index. Begg's and Egger's test were also performed to determine publication bias. All statistical data were analyzed by STATA software. The combined estimates did not show significant risks correlated with the FokI polymorphism. However, we found an increased risk in the subgroup analysis by source of control (OR = 1.11, 95% CI = 1.01-1.22; heterogeneity test: P = 0.116, I(2) = 0.0% for ff vs FF; OR = 1.10, 95% CI = 1.01-1.21; heterogeneity test: P = 0.832, I(2) = 0.0% for ff vs Ff + FF). This meta-analysis suggests that the presence of FokI polymorphism may contribute to the risk of breast cancer in Caucasians. PMID:24318991

    Fifty unrelated Basque males from southwest Idaho were typed for the 17 Y-STR loci in the Yfiler multiplex kit (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, YGATA H4.1 and DYS385a/b). In total, 42 haplotypes were identified, with no more than two individuals sharing a single haplotype. The haplotype diversity (HD) was 0.9935, and gene diversity (D) over loci was 0.457 ± 0.137. The Idaho Basque population was compared to the source population from the Basque autonomous region of Northern Spain and Southern France, as well as a United States Caucasian population. The haplotype diversity for the immigrant Basque sample is within 0.4% of the haplotype diversity of the European Basques (0.9903); thus the power of discrimination is similar for each population. The Idaho Basque population has less diversity in 9 out of 16 loci (considering DYS385a/b together) and 3% less diversity across all loci, compared to the European Basque population. A multidimensional scaling analysis (MDS) was created using pairwise R(ST) values to compare the Idaho Basques to other populations. Based upon R(ST) and F(ST) measures, no significant differentiation was found between the Idaho and source European Basque population. PMID:22276968

    Although type 2 diabetes is a chronic illness affecting the entire family, scant literature exists in this area. This study's purpose was to identify needs of family caregivers of persons with type 2 diabetes across cultures. Using a semi-structured interview guide with open-ended questions, a convenience sample of 33 family caregivers of American Indians (n = 14), African Americans (n = 11), and Caucasians (n = 8) with type 2 diabetes were interviewed by telephone. Qualitative content analysis was conducted based on five pre-determined categories derived from an existing conceptual model. Results were similar across groups and provided support for the conceptual model with themes emerging within the five pre-determined categories: (a) information about type 2 diabetes, (b) managing emotions and behaviors, (c) physical care, (d) instrumental care, and (e) personal responses to caregiving. No additional themes emerged. Although small and exploratory, findings provide information that may be useful to the future development of culturally based interventions. PMID:25505159

    Lactobionic acid was first found in a Caucasian fermented milk product popularly known as "Caspian Sea yogurt" in Japan. The presence of lactobionic acid in the fermented milk was indicated by the results of both high-performance anion-exchange chromatographic analysis with pulsed amperometric detection and mass spectrometric analysis. Thereafter, the acid was purified from the yogurt and analyzed by nuclear magnetic resonance. A substantial amount of lactobionic acid was found to be accumulated in the upper layer of the yogurt, especially within 10 mm from the surface. A total of 45 mg of lactobionic acid per 100 g of the upper yogurt layer was collected after 4 d of fermentation. The annual intake of lactobionic acid in individuals consuming 100 g of the yogurt every day would be 0.5 to 1.0 g. A lactose-oxidizing bacterium was isolated from the fermented milk and was identified as Acetobacter orientalis. Washed A. orientalis cells oxidized monosaccharides such as d-glucose at considerable rates, although their activities for substrates such as lactose, maltose, and cellobiose were much lower. When A. orientalis cells were cultivated in cow's milk, they exhibited lactose-oxidizing activity, suggesting that this bacterium was the main organism involved in the production of lactobionic acid in the yogurt.

    The non-specific symptoms the patients express upon the presentation of female bladder outlet obstruction make it a challenge to diagnose. There are subtle differences between the obstructed patient and those whose bladders are underactive and/or fail to mount a detrusor contraction. These disparities can be extracted through a thorough history and examination. At times, the clinician may utilize nomograms, non-invasive uroflow, and urodynamics with the addition of fluoroscopy to establish the diagnosis of obstruction. Management of the obstruction depends on the nature of the condition, whether functional or anatomical. The increase in the number of sling procedures performed to treat stress urinary incontinence has resulted in a rise in the number of iatrogenic obstructions. The temporal relationship between surgery and obstruction is the key to identifying the problem. PMID:26902625

    Objective Describe and evaluate risk factors for HIV/STIs among male-to-female (MTF) transgender persons. Method Using the Life Chart Interview, potential lifetime risk factors for HIV/STIs among MTFs were measured and evaluated in conjunction with lifetime exposures for HIV, syphilis, hepatitis B and hepatitis C. The participants were 517 MTFs between the ages of 19 and 59 from the New York Metropolitan Area. Results HIV/STIs were low among Caucasian Americans and very high among Hispanics and African Americans. In the latter groups, HIV and hepatitis B were associated with an androphillic sexual orientation, lifetime number of commercial sex partners (sex work), and the social expression of transgender identity; syphilis was associated with lifetime number of casual sex partners; hepatitis C was associated with injection drug use, unemployment, and social expression of transgender identity. In multivariate models, the social expression of transgender identity was the strongest and most consistent predictor of HIV/STIs. Consistent with their lower levels of infections, Caucasian Americans reported significantly lower levels of the risk factors found to be predictive of HIV/STI among Hispanics and African Americans. Conclusion HIV/STI prevention in this population should be targeted at Hispanic and African Americans. Prevention programs should incorporate multiple components designed to address the diverse issues confronting ethnic minority transgender persons, with an emphasis on the social expression of transgender identity.

    Caucasian (N = 47) and Southeast (SE) Asian (N = 36) families completed a questionnaire on their attitudes toward sleep, as well as a 7-day sleep diary for their children aged 5 to 11 years. Cultural differences were found in the perceived importance of sleep, particularly compared to homework and belief of how much sleep a child needs. Differences were also found in sleep-wake behaviors and amount of time spent on homework, with SE Asian children reporting a shift in sleep timing and increased homework load compared to Caucasian counterparts. Parental attitudes toward sleep, perception of sleep need, and homework load were not associated with the regulation of actual sleep behaviors in children, regardless of cultural heritage.

    Apolipoprotein-E {epsilon}4 (APOE-{epsilon}4) has been consistently associated with Alzheimer disease (AD) and may be responsible for an earlier age at onset. We have previously reported a diminished association between APOE-{epsilon}4 and AD in African Americans. Using a new method, which allows inclusion of censored information, we compared relative risks by APOE genotypes in an expanded collection of cases and controls from three ethnic groups in a New York community. The relative risk for AD associated with APOE-{epsilon}4 homozygosity was increased in all ethnic groups (African American relative risk [RR] = 3.0; 95% confidence interval [CI] = 1.5-5.9; Caucasian RR = 7.3, 95% CI = 2.5-21.6; and Hispanic RR = 2.5, 95% CI = 1.1-5.7), compared with those with APOE-{epsilon}3/{epsilon}3 genotypes. The risk was also increased for APOE-{epsilon}4 heterozygous Caucasians (RR = 2.9, 95% CI = 1.7-5.1) and Hispanics (RR = 1.6,95% CI = 1.1-2.3), but not for African Americans (RR = 0.6, 95% CI = 0.4-0.9). The age distribution of the proportion of Caucasians and Hispanics without AD was consistently lower for APOE-{epsilon}4 homozygous and APOE-{epsilon}4 heterozygous individuals than for those with other APOE genotypes. In African Americans this relationship was observed only in APOE-{epsilon}4 homozygotes. These results confirm that APOE genotypes influence the RR of AD in Caucasians and Hispanics. Differences in risk among APOE-{epsilon}4 heterozygote African Americans suggest that other genetic or environmental factors may modify the effect of APOE-{epsilon}4 in some populations. 58 refs., 3 figs., 4 tabs.

    Anti-Mullerian hormone (AMH) regulates ovarian folliculogenesis by signaling via its receptors, and elevated serum AMH levels are associated with an increased risk of breast cancer. No previous studies have examined the effects of genetic variants in AMH-related genes on breast cancer risk. We evaluated the associations of 62 single nucleotide polymorphisms (SNPs) in AMH and its receptor genes, including AMH type 1 receptor (ACVR1) and AMH type 2 receptor (AMHR2), with the risk of breast cancer in the Women's Insights and Shared Experiences (WISE) Study of Caucasians (346 cases and 442 controls), as well as African Americans (149 cases and 246 controls). Of the 62 SNPs evaluated, two showed a nominal significant association (P for trend < 0.05) with breast cancer risk among Caucasians, and another two among African Americans. The age-adjusted additive odds ratios (ORs) (95% confidence interval (95% CI)) of those two SNPs (ACVR1 rs12694937[C] and ACVR1 rs2883605[T]) for the risk of breast cancer among Caucasian women were 2.33 (1.20-4.52) and 0.68 (0.47-0.98), respectively. The age-adjusted additive ORs (95% CI) of those two SNPs (ACVR1 rs1146031[G] and AMHR2 functional SNP rs2002555[G]) for the risk of breast cancer among African American women were 0.63 (0.44-0.92) and 1.67 (1.10-2.53), respectively. However, these SNPs did not show significant associations after correction for multiple testing. Our findings do not provide strong supportive evidence for the contribution of genetic variants in AMH-related genes to the risk of developing breast cancer in either Caucasians or African Americans.

    Apolipoprotein-E epsilon 4 (APOE-epsilon 4) has been consistently associated with Alzheimer disease (AD) and may be responsible for an earlier age at onset. We have previously reported a diminished association between APOE-epsilon 4 and AD in African Americans. Using a new method, which allows inclusion of censored information, we compared relative risks by APOE genotypes in an expanded collection of cases and controls from three ethnic groups in a New York community. The relative risk for AD associated with APOE-epsilon 4 homozygosity was increased in all ethnic groups (African American relative risk [RR]=3.0; 95% confidence interval [CI]=1.5-5.9; Caucasian RR=7.3, 95% CI=2.5-21.6; and Hispanic RR=2.5, 95% CI=1.1-5.7), compared with those with APOE-epsilon 3/epsilon 3 genotypes. The risk was also increased for APOE-epsilon 4 heterozygous Caucasians (RR=2.9, 95% CI=1.7-5.1) and Hispanics (RR=1.6, 95% CI=1.1-2.3), but not for African Americans (RR=0.6, 95% Ci=0.4-0.9). The age distribution of the proportion of Caucasians and Hispanics without AD was consistently lower for APOE-epsilon 4 homozygous and APOE-epsilon 4 heterozygous individuals than for those with other APOE genotypes. In African Americans this relationship was observed only in APOE-epsilon 4 homozygotes. These results confirm that APOE genotypes influence the RR of AD in Caucasians and Hispanics. Differences in risk among APOE-epsilon 4 heterozygote African Americans suggest that other genetic or environmental factors may modify the effect of APOE-epsilon 4 in some populations. PMID:8644717

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to religious

    There are three endogamous subdivisions of the Hutterite population, a North American religious isolate. These individuals live on communal farms, and residence is strictly patrilocal. We report on the distributions of HLA-A and B alleles and haplotypes in 203 married women from one subdivision--the Dariusleut--in Alberta, Canada. We demonstrate that there is significant linkage disequilbrium among a large fraction of the distinct haplotypes in the Dariusleut Hutterite data; there is a restriction in the number of distinct haplotypes present in the Dariusleut; the Hutterites and the Old Order Amish (Lancaster County, Pennsylvania) are the most genetically distant pair of populations in an ensemble of 11 Caucasian populations; and, finally, the Old Order Amish and the Hutterites are approximately as distant from the Indiana Amish as they are from the eight other Caucasian populations, which are tightly clustered in the space of gene frequencies. These results are consistent with the fact that the Amish and the Hutterites are genetic isolates with small numbers of founders. Certain haplotypes show significant linkage disequilibrium in these as well as in other Caucasian samples. Thus, some of the linkage disequilibrium antedates the formation of these Anabaptist sects.

    Introduction The knowledge and study of surgical techniques and anthropometric measurements of the nose make possible a qualitative and quantitative analysis of surgical results. Objective Study the main technique used in rhinoplasty on Caucasian noses and compare preoperative and postoperative anthropometric measurements of the nose. Methods A prospective study with 170 patients was performed at a private hospital. Data were collected using the Electronic System Integrated of Protocols software (Sistema Integrado de Protocolos Eletrônicos, SINPE©). The surgical techniques used in the nasal dorsum and tip were evaluated. Preoperative and 12-month follow-up photos as well as the measurements compared with the ideal aesthetic standard of a Caucasian nose were analyzed objectively. Student t test and standard deviation test were applied. Results There was a predominance of endonasal access (94.4%). The most common dorsum technique was hump removal (33.33%), and the predominance of sutures (24.76%) was observed on the nasal tip, with the lateral intercrural the most frequent (32.39%). Comparison between preoperative and postoperative photos found statistically significant alterations on the anthropometric measurements of the noses. Conclusion The main surgical techniques on Caucasian noses were evaluated, and a great variety was found. The evaluation of anthropometric measurements of the nose proved the efficiency of the performed procedures. PMID:25992149

    Youths growing up in low-income inner-city neighborhoods are at substantial risk for initiating substance use, violent behavior, and sexual intercourse at early ages; these risk behaviors continue at comparatively high rates through adolescence. Hopelessness has been implicated as a risk factor for these behaviors. In this paper, we consider how race influences this process. African Americans form a demographic minority within the United States, but they are often the majority within inner-city neighborhoods. For Caucasians, the opposite typically holds. Mixed-race populations form a minority within both contexts. Using longitudinal data, we examine the relationship between race and risk behaviors in several impoverished inner-city neighborhoods where African Americans form the distinct majority and Caucasians and people of mixed racial heritage form a small minority. We also consider how race moderates the relationship between hopelessness and risk behavior. Our findings show that compared to Caucasian or mixed-race adolescents, African American adolescents are less likely to engage in risk behaviors, and that hopelessness has a less important impact on their behaviors.

    This study prospectively examined the course of depression in African American and Caucasian midlife women over an 11-year period. Racial differences in lifetime history of depression, severity of depressive symptoms and rates of depressive disorders at baseline, and persistence or recurrence of depression over an 11 year period were examined. Predictors of persistence/recurrence of depression were also examined. The sample was comprised of 423 midlife women enrolled in the Study of Women Across the Nation (SWAN) Mental Health Study (MHS). All participants completed baseline and annual assessments, which included self-reported measures of health, functioning, and psychosocial factors, and clinician administered assessments of psychiatric disorders. Logistic regression analyses were used to examine predictors of depression persistence/recurrence. Findings indicated that African American and Caucasian women did not differ significantly in rates of lifetime and baseline depressive disorders, or severity of depressive symptoms. Annual assessments revealed no significant differences between the groups in rates of persistent/recurrent depression. While African American and Caucasian women do not differ in recurrence of depression at midlife, factors associated with depression differed by race. PMID:24996377

    Female orgasmic disorder (FOD) is defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision, as a persistent or recurrent delay in, or absence of, orgasm following a 'normal' sexual excitement phase. FOD is a common problem affecting sexual function in a substantial proportion of women. Studies suggest that it is prevalent in 11-41% of women worldwide and can have a tremendous impact on the individual's quality of life, relational satisfaction and general well-being. The etiology of FOD tends to be multifactorial as it relates to genetics, medical conditions, medications, alcohol and drug use, other sexual dysfunctions, mental illness, life stressors, communication deficits and relationship issues. It is critical that sexual functioning in patients is assessed frequently through interview and/or validated questionnaires to aid in treatment strategy and/or referral. Currently, there are no approved medications to treat FOD. However, there are medications and psychological treatments that have shown promise in either treating FOD or thwarting the side effects of medications that can cause FOD. This chapter discusses the epidemiology and etiology of FOD and provides a comprehensive critical review of the literature on assessment and treatment of FOD. PMID:22005203

    The number of girls participating in sports has increased significantly since the introduction of Title XI in 1972. As a result, more girls have been able to experience the social, educational, and health-related benefits of sports participation. However, there are risks associated with sports participation, including the female athlete triad. The triad was originally recognized as the interrelationship of amenorrhea, osteoporosis, and disordered eating, but our understanding has evolved to recognize that each of the components of the triad exists on a spectrum from optimal health to disease. The triad occurs when energy intake does not adequately compensate for exercise-related energy expenditure, leading to adverse effects on reproductive, bone, and cardiovascular health. Athletes can present with a single component or any combination of the components. The triad can have a more significant effect on the health of adolescent athletes than on adults because adolescence is a critical time for bone mass accumulation. This report outlines the current state of knowledge on the epidemiology, diagnosis, and treatment of the triad conditions. PMID:27432852

    Colorectal cancer (CRC) incidence and mortality are higher in African Americans (AAs) than in Caucasian Americans (CAs) and microRNAs (miRNAs) have been found to be dysregulated in colonic and other neoplasias. The aim of this exploratory study was to identify candidate miRNAs that could contribute to potential biological differences between AA and CA colon cancers. Total RNA was isolated from tumor and paired adjacent normal colon tissue from 30 AA and 31 CA colon cancer patients archived at Stony Brook University (SBU) and Washington University (WU)-St. Louis Medical Center. miRNA profiles were determined by probing human genome-wide miRNA arrays with RNA isolated from each sample. Using repeated measures analysis of variance (RANOVA), miRNAs were selected that exhibited significant (p<0.05) interactions between race and tumor or significant (fold change >1.5, p<0.05) main effects of race and/or tumor. Quantitative polymerase chain reaction (q-PCR) was used to confirm miRNAs identified by microarray analysis. Candidate miRNA targets were analyzed using immunohistochemistry. RANOVA results indicated that miR-182, miR152, miR-204, miR-222 and miR-202 exhibited significant race and tumor main effects. Of these miRNAs, q-PCR analysis confirmed that miR-182 was upregulated in AA vs. CA tumors and exhibited significant race:tumor interaction. Immunohistochemical analysis revealed that the levels of FOXO1 and FOXO3A, two potential miR-182 targets, are reduced in AA tumors. miRNAs may play a role in the differences between AA and CA colon cancer. Specifically, differences in miRNA expression levels of miR-182 may contribute to decreased survival in AA colon cancer patients. PMID:24865442

    Breast cancer is the second most common cancer worldwide and the most common cancer reported in women. This malignant tumour is characterised by a number of specific features including uncontrolled cell proliferation. It ranks fifth in the world as a cause of cancer death overall in developed countries and is the second most frequent cause of cancer death in women. Early diagnosis increases 5-year survival rates up to 95%. Heparan sulfate proteoglycans (HSPGs) are complex proteins composed of a core protein to which a number of highly sulfated side chains attach, ubiquitous to the cell surface and within the extracellular matrix. HSPG side chains are synthesised by a highly co-ordinated process resulting in distinct sulfation patterns, which determine specific interactions with cell-signalling partners including growth factors, their receptors, ligands and morphogens. The enzymes responsible for chain initiation, elongation and sulfation are critical for creating HS chain variability conferring biological functionality. This study investigated a single nucleotide polymorphism in SULF1, the enzyme responsible for the 6-O desulfation of heparan sulfate side chains. We investigated this SNP in an Australian Caucasian case-control breast cancer population and found a significant association between SULF1 and breast cancer at both the allelic and genotypic levels (allele, p=0.016; genotype, p=0.032). Our results suggest that the rs2623047 SNP in SULF1 may impact breast cancer susceptibility. Specifically, the T allele of rs2623047 in SULF1 is associated with an increased risk of developing breast cancer in our cohort. The identification of markers including SULF1 may improve detection of this disease at its earliest stages improving patient treatment and prognosis. PMID:24911625

    Very few studies have investigated the determinants of serum vitamin D levels using a set of variables that include simultaneously sun exposure, phototype, dietary intake, sociodemographics, anthropometric, lifestyle data, and genetic polymorphisms. Our objective was to investigate the associations between all these parameters and vitamin D status in a large sample of French adults. This cross-sectional survey was based on 1,828 middle-aged Caucasian adults from the SU.VI.MAX (SUpplémentation en VItamines et Minéraux AntioXydants) study. Plasma 25-hydroxyvitamin D (25OHD) concentration was lower among women (P<0.0001), older subjects (P=0.04), obese/underweight (P<0.0001), those living at higher latitudes (P<0.0001), those whose blood draw occurred in early spring (P<0.0001), less physically active (P<0.0001), with low sun exposure (P<0.0001), and with no-to-low alcohol intake (P=0.0001). Mutant GC rs4588 and rs7041 single nucleotide polymorphisms were associated with lower and higher 25OHD concentrations, respectively (P<0.0001). Dietary intake was not a major determinant of vitamin D status (P=0.7). This study provides an overall picture of determinants of vitamin D status. Several modifiable factors were identified, such as daily-life moderate sun exposure, physical activity, and normal-weight maintenance, which should be targeted by public health policies in order to improve vitamin D status in the general population, while avoiding active/intensive sun exposure, in line with recommendations for skin cancer prevention.

    PURPOSE To explore whether disparities in outcomes exist between African-American (AA) and Caucasian (CS) men with low-grade prostate cancer (PCa) and similar Cancer of the Prostate Risk Assessment post-Surgery (CAPRA-S) features following prostatectomy (RP) METHODS The overall cohort consisted of 1,265 men (234 AA, and 1,031 CS) who met National comprehensive cancer network (NCCN) criteria for low-intermediate risk PCa and underwent RP between 1990 and 2012. We first evaluated whether clinical factors were associated with adverse pathologic outcomes and freedom from biochemical failure (FFbF) using the entire cohort. Next, we studied a subset of 705 men (112 AA, and 593 CS) who had pathologic Gleason score ≤6 (low-grade disease). Using this cohort, we determined whether race impacted FFbF in men with prostatectomy-proven low-grade disease and similar CAPRA-S score. RESULTS With a median follow up time of 27 months, the overall 7-year FFbF rate was 86% vs. 79% in CS and AA men, respectively (p=0.035). There was no significant difference in ≥1 adverse pathologic features between CS vs. AA men (27% vs. 31%; P =0.35) or CAPRA-S score (p=0.28). In the subset analysis of patients with low-grade disease, AA race was associated with worse FFbF outcomes (p=0.002). Furthermore, AA race was a significant predictor of FFbF in men with low-grade disease (HR 2.01, 95%CI 1.08–3.72; p=0.029). CONCLUSIONS AA race is a predictor of worse FFbF outcomes in men with low-grade disease after RP. These results suggest that a subset of AA men with low-grade disease may benefit from more aggressive treatment. PMID:25304288

    The objectives of the present study were to develop and cross-validate new equations for predicting resting energy expenditure (REE) in severely obese children and adolescents, and to determine the accuracy of new equations using the Bland-Altman method. The subjects of the study were 574 obese Caucasian children and adolescents (mean BMI z-score 3.3). REE was determined by indirect calorimetry and body composition by bioelectrical impedance analysis. Equations were derived by stepwise multiple regression analysis using a calibration cohort of 287 subjects and the equations were cross-validated in the remaining 287 subjects. Two new specific equations based on anthropometric parameters were generated as follows: (1) REE=(Sex x 892.68)-(Age x 115.93)+(Weight x 54.96)+(Stature x 1816.23)+1484.50 (R(2) 0.66; se 1028.97 kJ); (2) REE=(Sex x 909.12)-(Age x 107.48)+(fat-free mass x 68.39)+(fat mass x 55.19)+3631.23 (R(2) 0.66; se 1034.28 kJ). In the cross-validation group, mean predicted REE values were not significantly different from the mean measured REE for all children and adolescents, as well as for boys and for girls (difference <2 %) and the limits of agreement (+/-2 sd) were +2.06 and -1.77 MJ/d (NS). The new prediction equations allow an accurate estimation of REE in groups of severely obese children and adolescents. These equations might be useful for health care professionals and researchers when estimating REE in severely obese children and adolescents. PMID:17092390

    From 11 studies, a total of 1,792 Caucasian probands with insulin-dependent diabetes mellitus (IDDM) are analyzed. Antigen genotype frequencies in patients, transmission from affected parents to affected children, and the relative frequencies of HLA-DR3 and -DR4 homozygous patients all indicate that DR3 predisposes in a “recessive”-like and DR4 in a “dominant”-like or “intermediate” fashion, after allowing for the DR3/DR4 synergistic effect. Removal of DR3 and DR4 reveals an overall protective effect of DR2, predisposing effects of DR1 and DRw8, and a slight protective effect of DR5 and a predisposing effect of DRw6. Analysis of affected-parent-to-affected-child data indicates that a subset of DR2 may predispose. The non-DR3, non-DR4 antigens are not independently associated with DR3 and DR4; the largest effect is a deficiency of DR2, followed by excesses of DR1, DRw8, and DRw6, in DR4 individuals, as compared with DR3 individuals. HLA-B locus distributions on patient haplotypes indicate that only subsets of both DR3 and DR4 are predisposing. The presence or absence of Asp at position 57 of the DQβ gene, recently implicated in IDDM predisposition, is not by itself sufficient to explain the inheritance of IDDM. At a minimum, the distinguishing features of the DR3-associated and DR4-associated predisposition remain to be identified at the molecular level. Risk estimates for sibs of probands are calculated based on an overall sibling risk of 6%; estimates for those sharing two, one, or zero haplotypes are 12.9%, 4.5%, and 1.8%, respectively. Risk estimates subdivided by the DR type of the proband are also calculated, the highest being 19.2% for sibs sharing two haplotypes with a DR3/DR4 proband. PMID:3057885

    Sensorineural hearing loss is the most frequent sensory deficit of childhood and is of genetic origin in up to 75% of cases. It has been shown that mutations of the SLC26A4 (PDS) gene were involved in syndromic deafness characterized by congenital sensorineural hearing impairment and goitre (Pendred's syndrome), as well as in congenital isolated deafness (DFNB4). While the prevalence of SLC26A4 mutations in Pendred's syndrome is clearly established, it remains to be studied in large cohorts of patients with nonsyndromic deafness and detailed clinical informations. In this report, 109 patients from 100 unrelated families, aged from 1 to 32 years (median age: 10 years), with nonsyndromic deafness and enlarged vestibular aqueduct, were genotyped for SLC26A4 using DHPLC molecular screening and sequencing. In all, 91 allelic variants were observed in 100 unrelated families, of which 19 have never been reported. The prevalence of SLC26A4 mutations was 40% (40/100), with biallelic mutation in 24% (24/100), while six families were homozygous. All patients included in this series had documented deafness, associated with EVA and without any evidence of syndromic disease. Among patients with SLC26A4 biallelic mutations, deafness was more severe, fluctuated more than in patients with no mutation. In conclusion, the incidence of SLC26A4 mutations is high in patients with isolated deafness and enlarged vestibular aqueduct and could represent up to 4% of nonsyndromic hearing impairment. SLC26A4 could be the second most frequent gene implicated in nonsyndromic deafness after GJB2, in this Caucasian population. PMID:16570074

    Aging is a complex process that is accompanied with changes in both muscle mass and muscle function (strength and performance). Therefore, the current longitudinal study aimed to provide a better insight in 10-year aging-related changes in whole-body muscle mass and strength performance of the leg extensors during the adult life span. Data were gathered within the framework of the first- (2002-2004: baseline) and third-generation Flemish Policy Research Center Sport (2012-2014: follow-up). Results are based on muscle characteristics data of 591 Flemish Caucasian adults (19-73 years, 381 men). Skeletal muscle mass (SMM) was determined with bioelectrical impedance analysis. Biodex Medical System 3® dynamometer was used to measure isometric (PTstatic120°) and isokinetic (PTdynamic60° and PTdynamic240°) strength, ballistic movement speed (S 20 %), and muscular endurance (work) of the knee extensors. Overall strength performance was higher at both evaluation moments in men compared to women (p < 0.01). But only S 20 % declined significantly faster in men compared to women (p < 0.01). Age and baseline strength performance were negatively related with the change in strength performance, even when corrected for SMM, protein intake, and energy expenditure during sports (E sport). In conclusion, strength performance was not associated with E sport in this study, but protein intake was associated with isometric strength in men, and with ballistic and isokinetic strength in women. Changes in S 20 % were significantly greater in men compared to women. Baseline values of strength performance and age were associated with changes in strength performance parameters, even after correction for SMM, protein intake, and E sport. PMID:26961694

    Diet is known to play a major role in the symptoms of the inflammatory bowel disease, Crohn's disease (CD). Although no single diet is appropriate to all individuals, most CD patients are aware of foods that provide adverse or beneficial effects. This study seeks to categorise foods in relation to their effects on symptoms of CD, in a New Zealand Caucasian population. Four hundred and forty-six subjects from two different centres in New Zealand were recruited into the study. An extensive dietary questionnaire (257 food items in 15 groups) recorded self-reported dietary tolerances and intolerances. Across each of the food groups, there were statistically significant differences among responses to foods. A two-dimensional graphical summary enabled stratification of foods according to the probability that they will be either beneficial or detrimental. A small number of foods are frequently considered to be beneficial, including white fish, salmon and tuna, gluten-free products, oatmeal, bananas, boiled potatoes, sweet potatoes (kumara), pumpkin, soya milk, goat's milk and yoghurt. Foods that are typically considered detrimental include grapefruit, chilli or chilli sauce, corn and corn products, peanuts, cream, salami, curried foods, cola drinks, high energy drinks, beer, and red wine. For a number of the food items, the same item that was beneficial for one group of subjects was detrimental to others; in particular soya milk, goat's milk, yoghurt, oatmeal, kiwifruit, prunes, apple, broccoli, cauliflower, linseed, pumpkin seed, sunflower seed, ginger and ginger products, beef, lamb, liver, and oily fish. It was not possible to identify a specific group of food items that should be avoided by all CD patients. The wide range of detrimental items suggests that dietary maintenance of remission is likely to be difficult, and to exclude a substantial number of foods. Personalised diets may be especially important to these individuals. PMID:20144628

  15. Female Sexual Arousal in Amphibians

    2010-01-01

    Rather than being a static, species specific trait, reproductive behavior in female amphibians is variable within an individual during the breeding season when females are capable of reproductive activity. Changes in receptivity coincide with changes in circulating estrogen. Estrogen is highest at the point when females are ready to choose a male and lay eggs. At this time female receptivity (her probability of responding to a male vocal signal) is highest and her selectivity among conspecific calls (measured by her probability of responding to a degraded or otherwise usually unattractive male signal) is lowest. These changes occur even though females retain the ability to discriminate different acoustic characteristics of various conspecific calls. After releasing her eggs, female amphibians quickly become less receptive and more choosy in terms of their responses to male sexual advertisement signals. Male vocal signals stimulate both behavior and estrogen changes in amphibian females making mating more probable. The changes in female reproductive behavior are the same as those generally accepted as indicative of a change in female sexual arousal leading to copulation. They are situationally triggered, gated by interactions with males, and decline with the consummation of sexual reproduction with a chosen male. The changes can be triggered by either internal physiological state or by the presence of stimuli presented by males, and the same stimuli change both behavior and physiological (endocrine) state in such a way as to make acceptance of a male more likely. Thus amphibian females demonstrate many of the same general characteristics of changing female sexual state that in mammals indicate sexual arousal. PMID:20816968

    2013-01-01

    Female pattern hair loss (FPHL) is a common cause of hair loss in women characterized by diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline. Its prevalence increases with advancing age and is associated with significant psychological morbidity. The pathophysiology of FPHL is still not completely understood and seems to be multifactorial. Although androgens have been implicated, the involvement of androgen-independent mechanisms is evident from frequent lack of clinical or biochemical markers of hyperandrogenism in affected women. The role of genetic polymorphisms involving the androgen and estrogen receptors is being increasingly recognized in its causation and predicting treatment response to anti-androgens. There are different clinical patterns and classifications of FPHL, knowledge of which facilitates patient management and research. Chronic telogen effluvium remains as the most important differential diagnosis. Thorough history, clinical examination, and evaluation are essential to confirm diagnosis. Patients with clinical signs of androgen excess require assessment of biochemical parameters and imaging studies. It is prudent to screen the patients for metabolic syndrome and cardiovascular risk factors. The treatment comprises medical and/or surgical modalities. Medical treatment should be initiated early as it effectively arrests hair loss progression rather than stimulating regrowth. Minoxidil continues to be the first line therapy whereas anti-androgens form the second line of treatment. The progressive nature of FPHL mandates long-term treatment for sustained effect. Medical therapy may be supplemented with cosmetic concealment in those desirous of greater hair density. Surgery may be worthwhile in some carefully selected patients. PMID:23974580

  17. Female urinary incontinence rehabilitation.

    PubMed

    Di Benedetto, P

    2004-08-01

    Pelvic floor rehabilitation (PFR) is an important and recommended strategy for the treatment of many urogynecological disorders including urinary incontinence (UI). The recognised pioneer of PFR is the American gynecologist Arnold Kegel who, over 50 years ago, proposed pelvic floor muscle exercises (PFME) to prevent and/or treat female UI. Kegel's techniques were successfully used by others too, but as the years passed these techniques sank into unjustified oblivion. In the 1980s in Europe the medical world's interest in PFME techniques gained ground, contemporaneously with functional electrical stimulation (FES) and biofeedback (BFB). As a general rule, the least invasive and least dangerous procedure for the patient should be the first choice, and behavioural and rehabilitative techniques should be considered as the first line of therapy for UI. The behavioural approaches in women with UI and without cognitive deficits are tailored to the patient's underlying problem, such as bladder training or retraining (BR) for urge UI. BR has many variations but generally consists of education, scheduled voiding, and positive reinforcements. The rehabilitative approaches comprise BFB, FES, PFME, and vaginal cones (VC). BFB allows the subject to modify the unconscious physiological events, while FES is aimed at strengthening perineal awareness, increasing the tone and trophism of the pelvic floor, and inhibiting detrusor overactivity. PFME play an extremely important role in the conservative treatment of UI and overactive bladder, and many studies have demonstrated their effectiveness. Many authors have used the different methods for PFR in a heterogeneous manner: the best results were obtained when protocols requiring the contemporary use of 2 or more techniques were followed.

    Atypical fibroxanthoma (AFX) is an uncommon spindle cell tumor with intermediate or borderline malignant potential. Clinically, it may be misdiagnosed as a squamous cell carcinoma (SCC) or malignant melanoma. Solar irradiation has been implicated in its pathogenesis. The diagnosis of AFX rests on a combination of histopathological features and a negative immunohistochemical profile. AFX is a rare tumor usually found in sun exposed skin of head and neck region in elderly Caucasian men. Rarely, it has a second peak in young adults, where it is found in trunk and extremities. The present case is reported as AFX is quite unusual in a young female with a nodule in the leg which was clinically diagnosed as a malignant melanoma. Only a few cases of AFX have been reported in young women. This case highlights the fact that accurate diagnosis of atypical fibroxanthoma is very crucial so as to avoid overenthusiastic and overzealous treatment as required for a malignant tumor.

    Though the number of female medical graduates has increased throughout the world, their postgraduate professional achievements are said to be suboptimal. Our aim is to look into the achievements of Sudanese female pediatricians and compare them with their male counterparts. A cross sectional study was undertaken using a questionnaire involving pediatricians working in the universities and Ministry of Health, Sudan. Ninety five (65.1%) out of 146 pediatricians responded; 73 (76.8%) were females and 22 (23.2%) were males. Thirty (41%) Of the females were in the academic career. Only 2 (8.3%) out of 24 assistant professors were promoted to associate professors and non of the four associate professors managed to become a professor compared to 68% and 25% among males, respectively. Twenty three (76.6%) of females compared to 31% of males had no publications. Nineteen out of 21 females (90.4%) who have been offered training opportunities abroad declined the offer for family reasons. Fifty four (93%) female pediatricians declined to work outside the capital state. No nursery facilities were available at work place. The main reasons for inadequate achievements included family issues, cultural obstacles, lack of mentorships and unsatisfying work environment and facilities. Suggestions were put forward to improve on these problems. Though female doctors are the majority of undergraduate and graduate students in Sudan, their professional and academic achievements after specialization are not optimal mainly for socio-cultural reasons and these need to be addressed.

    1996-04-01

    The literature on erotic transference and countertransference between female analyst and male patient is reviewed and discussed. It is known that female analysts are less likely than their male colleagues to act out sexually with their patients. It has been claimed that a) male patients do not experience sustained erotic transferences, and b) female analysts do not experience erotic countertransferences with female or male patients. These views are challenged and it is argued that, if there is less sexual acting out by female analysts, it is not because of an absence of eros in the therapeutic relationship. The literature review covers material drawn from psychoanalysis, feminist psychotherapy, Jungian analysis, as well as some sociological and cultural sources. It is organized under the following headings: the gender of the analyst, sexual acting out, erotic transference, maternal and paternal transference, gender and power, countertransference, incest taboo--mothers and sons and sexual themes in the transference.

    Due to cultural and religious reasons, Pakistani women can be reluctant to seek medical attention for disorders affecting their genitals or breasts. As a result, in the case of cervical and breast cancers, oncological treatment is often not received until the diseases are in the late stages. Once a cancer is classified and the tumor marked, the role of the medical physicist begins. Medical physicists' responsibilities include treatment planning, supervising treatment through radiation, dosimetry, contouring, training, equipment selection, education, research, and supervising radiotherapy facilities. In brachytherapy, isotopes are placed at the tumor site in the form of wires or seeds. There are very few female medical physicists in Pakistan. This leads to further hesitation on the part of many women to seek treatment. To help female patients obtain needed medical care, female physics students should be encouraged to pursue the emerging field of medical physics. This would provide a new professional opportunity for female physics students and give comfort to female patients.

    Obstructive sleep apnea (OSA) is more common in men than women. Body size is greater in males (sexual dimorphism), but large body habitus is associated with OSA for both genders. We speculated that male-female phenotypical convergence (reduced sexual dimorphism via identical phenotype acquisition) occurs with OSA and tested hypotheses: (1) phenotypical features pathogenic for OSA differ between OSA and healthy subjects irrespective of gender; and (2) such characteristics exhibit phenotypical convergence. Utilizing an existing database, we calculated male-female (group average) ratios for eight anthropometric and 33 surface cephalometric variables from 104 Caucasian OSA patients [72 males; apnea-hypopnea index (events h(-1) ): males: 42.3 ± 24.7 versus females: 42.6 ± 26.1 (P > 0.9)] and 85 Caucasian, healthy, non-OSA, community volunteers (36 males). Log-transformed data were analysed using a general linear model with post-hoc unpaired t-tests and significance at P < 0.0012 (Bonferroni multiple-comparison correction). OSA patients were older (56.9 ± 14.4 versus 38.0 ± 13.8 years), but there were no within-group gender-based age differences. All anthropometric variables (except height), plus cranial base width, mandibular breadth and retromandibular width diagonal were larger in gender-matched OSA versus healthy comparisons; thus satisfying hypothesis (1). Male-female ratios were mostly >1.0 across groups, but with no significant group × gender interactions no variable satisfied hypothesis (2). Thus, in this exploratory study, OSA patients had gender-common phenotypical differences to healthy subjects, but sexual dimorphism was preserved. Lack of complete phenotypical convergence may indicate gender-based critical phenotype-level attainment for OSA and/or gender-based OSA prevalence arises from factors other than those in this study.

    The World Health Organization estimates that the number of obese and overweight adults has increased to 1.6 billion, with concomitant increases in comorbidity. While genetic factors for obesity have been extensively studied in Caucasians, fewer studies have investigated genetic determinants of body mass index (BMI; weight (kg)/height (m)2) in African Americans. A total of 38 genes and 1,086 single nucleotide polymorphisms (SNPs) in African Americans (n = 1,173) and 897 SNPs in Caucasians (n = 1,165) were examined in the Southern Community Cohort Study (2002–2009) for associations with BMI and gene × environment interactions. A statistically significant association with BMI survived correction for multiple testing at rs4140535 (β = −0.04, 95% confidence interval: −0.06, −0.02; P = 5.76 × 10−5) in African Americans but not in Caucasians. Gene-environment interactions were observed with cigarette smoking and a SNP in ADIPOR1 in African Americans, as well as between a different SNP in ADIPOR1 and physical activity in Caucasians. A SNP in PPARGC1A interacted with alcohol consumption in African Americans, and a different SNP in PPARGC1A was nominally associated in Caucasians. A SNP in CYP19A1 interacted with dietary energy intake in African Americans, and another SNP in CYP191A had an independent association with BMI in Caucasians. PMID:22106445

    We report here our analysis of HLA class II alleles in 180 Caucasian nuclear families with at least two children with insulin-dependent diabetes mellitus (IDDM). DRB1, DQA1, DQB1, and DPB1 genotypes were determined with PCR/sequence-specific oligonucleotide probe typing methods. The data allowed unambiguous determination of four-locus haplotypes in all but three of the families. Consistent with other studies, our data indicate an increase in DR3/DR4, DR3/DR3, and DR4/DR4 genotypes in patients compared to controls. In addition, we found an increase in DR1/DR4, DR1/DR3, and DR4/DR8 genotypes. While the frequency of DQB1*0302 on DR4 haplotypes is dramatically increased in DR3/DR4 patients, DR4 haplotypes in DR1/DR4 patients exhibit frequencies of DQB1*0302 and DQB1*0301 more closely resembling those in control populations. The protective effect of DR2 is evident in this data set and is limited to the common DRB1*1501-DQB1*0602 haplotype. Most DR2{sup +} patients carry the less common DR2 haplotype DRB1*1601-DQB1*0502, which is not decreased in patients relative to controls. DPB1 also appears to play a role in disease susceptibility. DPB1*0301 is increased in patients (P < .001) and may contribute to the disease risk of a number of different DR-DQ haplotypes. DPB1*0101, found almost exclusively on DR3 haplotypes in patients, is slightly increased, and maternal transmissions of DRB1*0301-DPB1*0101 haplotypes to affected children occur twice as frequently as do paternal transmissions. Transmissions of DR3 haplotypes carrying other DPB1 alleles occur at approximately equal maternal and paternal frequencies. The complex, multigenic nature of HLA class II-associated IDDM susceptibility is evident from these data. 76 refs., 1 fig., 7 tabs.

    2013-12-01

    "Female genital circumcision" or "female genital mutilation", as it is called more often, is an operation that is primarily carried out in Africa. Owing to migration, physicians are increasingly confronted with this issue in Western countries as well. A range of negative effects may result from this operation and this article aims to address consequences for female pelvic health. Special emphasis is placed on urogynaecological health consequences; in particular, on "voiding difficulties", "recurrent urinary tract infections" and "vesicovaginal fistula". All of these occur mostly in infibulated women, i.e. in women whose genitalia are sealed by the most severe form of circumcision. Some of the problems that may emerge as a result of the operation can be resolved by defibulation (i.e. surgical reopening of the sealed vulva). Female genital circumcision is a sensitive topic even in the area of research and reliable data are therefore scarce. PMID:23857065

    This case describes a 31-year-old female Caucasian patient with complaints of ongoing depression, agitation, and severe panic attacks. The patient was untreated until a recent unsuccessful trial of citalopram followed by venlafaxine which produced a partial response. Genetic testing was performed to assist in treatment decisions and revealed the patient to be heterozygous for polymorphisms in 5HT2C, ANK3, and MTHFR and homozygous for a polymorphism in SLC6A4 and the low activity (Met/Met) COMT allele. In response to genetic results and clinical presentation, venlafaxine was maintained and lamotrigine was added leading to remission of agitation and depression. PMID:24744941

    Classical autism or autistic disorder belongs to a group of genetically heterogeneous conditions known as Autism Spectrum Disorders (ASD). Heritability is estimated as high as 90% for ASD with a recently reported compilation of 629 clinically relevant candidate and known genes. We chose to undertake a descriptive next generation whole exome sequencing case study of 30 well-characterized Caucasian females with autism (average age, 7.7 ± 2.6 years; age range, 5 to 16 years) from multiplex families. Genomic DNA was used for whole exome sequencing via paired-end next generation sequencing approach and X chromosome inactivation status. The list of putative disease causing genes was developed from primary selection criteria using machine learning-derived classification score and other predictive parameters (GERP2, PolyPhen2, and SIFT). We narrowed the variant list to 10 to 20 genes and screened for biological significance including neural development, function and known neurological disorders. Seventy-eight genes identified met selection criteria ranging from 1 to 9 filtered variants per female. Five females presented with functional variants of X-linked genes (IL1RAPL1, PIR, GABRQ, GPRASP2, SYTL4) with cadherin, protocadherin and ankyrin repeat gene families most commonly altered (e.g., CDH6, FAT2, PCDH8, CTNNA3, ANKRD11). Other genes related to neurogenesis and neuronal migration (e.g., SEMA3F, MIDN), were also identified. PMID:25574603

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C. PMID:23515242

    Purpose The purpose of this study was to explore gender differences in lay knowledge of type 2 diabetes symptoms among community-dwelling Caucasian, Latino, Filipino, and Korean Americans. Design and Methods A cross-sectional survey was administered to a convenience sample of 904 adults (172 Caucasians, 248 Latinos, 234 Koreans, and 250 Filipinos) without diabetes at community events, community clinics, churches, and online in the San Francisco Bay Area and San Diego from August to December 2013. Participants were asked to describe in their own words signs and/or symptoms of diabetes. A multiple logistic regression analysis was performed to examine the association of lay symptom knowledge with gender after controlling for potential confounding factors. Results Overall, the average age of the sample populations was 44 (SD ±16.1) years, 36% were male, and 58% were married. Increased thirst/dry mouth following increased urinary frequency/color/odor and increased fatigue/lethargy/low energy were the most frequently reported signs and symptoms (19.8%, 15.4%, and 13.6%, respectively). After controlling for known confounding factors, women were 1.6 (95% confidence interval, 1.2-2.3, P = .004) times more likely than men to report at least 1 diabetes symptom. However, this gender difference in knowledge of diabetes signs and symptoms did not significantly differ across Caucasians, Latinos, Filipinos, and Korean Americans (P = .87). Conclusion The findings underscore the importance of improving public knowledge and awareness of signs and symptoms of diabetes, particularly in men. PMID:25227121

    The aim of this study was to analyze the impact of core variations on sustained virological response (SVR) to pegylated interferon plus ribavirin (PEG-IFN/RBV) and its association with predictive factors of response in Caucasian patients infected with genotype 1 hepatitis C virus (HCV-1). Full-length core sequences were analyzed in 100 Caucasian HCV-1-infected patients who received therapy with PEG-IFN/RBV. The associations between variations in the core protein and SVR, as well as with predictors of SVR, were analyzed. Variations at core 62, 70 and 110 were selected as candidates. There were almost no variations at these positions among patients harboring HCV-1a. However, they were identified in 10 (30.3 %), 21 (63.6 %) and 13 (39.4 %) subjects with HCV-1b, respectively. Among the HCV-1b patients, 39.1 % individuals carrying core R62 and 70 % subjects with core R62G showed SVR (p = 0.141), and 66.7 % of HCV-1b patients harboring core R70 and 38.1 % with core R70Q achieved SVR (p = 0.157), whereas the rate of SVR was 70 % for individuals with core T110 and 15.4 % for those with core T110N (p = 0.004). No statistical interaction between core variations and IL28B genotype was observed. Patients with R70 showed higher median (interquartile range) baseline plasma levels of low-density-lipoprotein cholesterol (LDL-C) than those with R70Q (96 [86-118] mg/dL vs. 76 [54-88] mg/dL, p = 0.014). We concluded that a substitution at core 110 is associated with a lower rate of SVR in Caucasian HCV-1b-infected patients receiving PEG-IFN/RBV. Furthermore, the variation at the core 70 position is related to plasma levels of LDL-C in these patients. PMID:25161034

    Objectives The OPRL1 gene encodes the nociceptin/orphanin FQ receptor (NOP-R), which plays a role in regulating tolerance and behavioral responses to morphine. However, there is limited information on whether variants of OPRL1 are associated with vulnerability to develop opiate addiction. In this study, we examined five variants of OPRL1 and their role in determining vulnerability to develop opiate addiction. Methods We recruited 447 subjects: 271 former severe heroin addicts and 176 healthy controls. Using a 5′-fluorogenic exonuclease assay (TaqMan®), we genotyped subjects at five variants in OPRL1. It was then determined whether there was a significant association of allele, genotype, or haplotype frequency with vulnerability to develop opiate addiction. Results When the cohort was stratified by ethnicity, we found that, in Caucasians but not in African Americans or Hispanics, the allele frequency of rs6090041 and rs6090043 were significantly associated point-wise with opiate addiction (P = 0.03 and 0.04, respectively). Of the haplotypes formed by these two variants, one haplotype was found to be associated with protection from developing opiate addiction in both African Americans (point-wise P = 0.04) and Caucasians (point-wise P = 0.04), and another haplotype with vulnerability to develop opiate addiction in Caucasians only (P = 0.020). Conclusions This study provides evidence for an association of two variants of the OPRL1 gene, rs6090041 and rs6090043, with vulnerability to develop opiate addiction, suggesting a role for NOP-R in the development of opiate addiction.

    Historically, pepper spray product potency has been established using a taste test evaluation. A taste test is subjective and may not be appropriate for assessing pepper potency in skin. The current study evaluated chemically diverse pepper sprays in human forearm skin using three objective, noninvasive parameters: transepidermal water loss, skin surface temperature and erythema, as a means for assessing dermal pharmacology, toxicology and product potency. Five commercial pepper spray products containing various capsaicinoid analogs at various concentrations were evaluated in duplicate on volar forearms of six Caucasians and six Asians using a 10 min exposure. Mean surface skin temperature, transepidermal water loss results were highly variable and therefore did not demonstrate dose responsive behavior to increasing capsaicinoid concentrations. Erythema, as measured by increases in a* (reflected light in the red-to-green color spectrum) of the L*a*b* uniform color scale, was superior among parameters evaluated in discriminating pepper spray potency and correlated well with the relative and total capsaicinoid concentration in the products. Products containing greater than 16 mg ml(-1) capsaicinoid concentration produced greater erythema responses in Caucasians than Asians. Asians responded greater to the synthetic analog, nonivamide, than to mixtures of capsaicinoids, while Caucasians responded equally to both capsaicinoid analogs. Thus, pepper spray product potency in human skin reflects the total capsaicinoid concentration, the specific capsaicin analog(s) present, and the race of the individual exposed. The finding that the reflectance colorimeter a* scale can differentiate these parameters in skin will have a significant impact on evaluating the use and efficacy of pepper spray products in humans.

  4. Female condom becomes available nationwide.

    PubMed

    1995-01-01

    Between May 1993 and August 1994, only family planning and sexually transmitted disease (STD) clinics had the female condom available. The manufacturer is using a print and educational campaign to market the female condom. The print campaigns provide a toll-free number for consumers and health care providers. The educational component consists of community outreach programs for public health, family planning clinics, and university health centers. The single-use soft polyurethane sheath has a flexible ring at the closed end, which is used to insert the condom and holds it over the cervix. A flexible ring is at the outer end; it holds the condom over the labia. The female condom is prelubricated and comes with a bottle of lubricant. Adding extra lubricant on the penis or the inside of the condom can prevent invagination of the outer ring, the penis entering the vagina instead of the condom, or the condom riding the penis. The 1-year failure rate is 25% for average use and 5.1% for perfect use. Correct and consistent use determines the female condom's ability to protect against STDs and HIV. The female condom helps women protect themselves against pregnancy and STDs/HIV when their male partner refuses to use a latex condom. Since it is visible outside the vagina, some women might still find it difficult to negotiate its use. Drawbacks of the female condom are that it is cumbersome and challenges our traditional gender roles and ideas about sexuality. Education addressing how women feel about themselves, their sexuality, and their relationships is needed to increase female condom use and acceptance. Some couples prefer the female condom over the male condom because it is roomier and because the polyurethane creates a better sensation than latex. PMID:12288570

  5. The functionality of female reciprocal calls in the Iberian midwife toad (Alytes cisternasii): female-female acoustic competition?

    Female midwife toads (genus Alytes) emit highly variable reciprocal calls of unclear function prior to and during courtship. In some species, female-female competition, expressed as physical fighting, has been reported. Males of Majorcan midwife toads (Alytes muletensis) show phonotactic response to female calls, and females of Iberian midwife toads (Alytes cisternasii) respond differently according to the male call characteristics. In this study, I test the hypothesis of female-female acoustic competition as an additional function of female reciprocal calls. Playback tests indicate that female calls are not clearly involved in female acoustic competition in the Iberian midwife toad, therefore female calls could be directed at males rather than towards competitive females.

    Cancer is a leading cause of death worldwide. The cancer incidence rate in Chile is 133.7/100,000 inhabitants and it is the second cause of death, after cardiovascular diseases. Most of the antineoplastic drugs are metabolized to be detoxified, and some of them to be activated. Genetic polymorphisms of drug-metabolizing enzymes can induce deep changes in enzyme activity, leading to individual variability in drug efficacy and/or toxicity. The present research describes the presence of genetic polymorphisms in the Chilean population, which might be useful in public health programs for personalized treatment of cancer, and compares these frequencies with those reported for Asian and Caucasian populations, as a contribution to the evaluation of ethnic differences in the response to chemotherapy. We analyzed 23 polymorphisms in a group of 253 unrelated Chilean volunteers from the general population. The results showed that CYP2A6*2, CYP2A6*3, CYP2D6*3, CYP2C19*3, and CYP3A4*17 variant alleles are virtually absent in Chileans. CYP1A1*2A allele frequency (0.37) is similar to that of Caucasians and higher than that reported for Japanese people. Allele frequencies for CYP3A5*3(0.76) and CYP2C9*3(0.04) are similar to those observed in Japanese people. CYP1A1*2C(0.32), CYP1A2*1F(0.77), CYP3A4*1B(0.06), CYP2D6*2(0.41), and MTHFR T(0.52) allele frequencies are higher than the observed either in Caucasian or in Japanese populations. Conversely, CYP2C19*2 allelic frequency (0.12), and genotype frequencies for GSTT1 null (0.11) and GSTM1 null (0.36) are lower than those observed in both populations. Finally, allele frequencies for CYP2A6*4(0.04), CYP2C8*3(0.06), CYP2C9*2(0.06), CYP2D6*4(0.12), CYP2E1*5B(0.14), CYP2E1*6(0.19), and UGT2B7*2(0.40) are intermediate in relation to those described in Caucasian and in Japanese populations, as expected according to the ethnic origin of the Chilean population.

    The Caucasus is a part of huge Late Cenozoic Alpine-Himalayan zone collision of continental plates, lasted throughout the Eurasian continent. At that the Greater Caucasus is an edge of the Eurasian plate, raised along the large reverse fault - the Main Caucasian Fault. This fault, in turn, is a part of the super-fault, stretching from the Kopetdag to the Trans-European Suture Zone (zone Tornquist-Teisseyre). The Caucasus is limited from its both sides by large depressions of Black and Caspian seas, which "cut off" pre-Pliocene structures both the Caucasus and the Kopetdag; origin of these seas is associated with downward currents in the mantle ("cold plumes"). The peculiar structure of the region is north-south Transcaucasian Rise, which is located in the northern part of Caucasian-Arabian syntaxis. Large positive isostatic anomaly is confined with it, apparently indicating presence here of the mantle plume head. Along the zone of syntaxis the belt of Neogene-Quaternary volcanism occurs which begins in Eastern Anatolia and traced through the Lesser to Greater Caucasus. Two types of volcanic rocks are represented here: (1) prevailing volcanics of calc-alkaline series, very close in petrological and geochemical characteristics to suprasubduction type, and (2) extensive lava plateaus formed by basalts of intraplate (plume related) type. However, subduction zone under the Caucasus region, as well as throughout the Caucasian-Arabian syntaxis, is absent and relatively shallow earthquakes (50-60 km) are dominated here. We considered that origin of calc-alkaline magmas is associated with interaction between the mantle plume head, and crustal material at shallow depths under conditions of deformation at high pressures, leading to melting of the material in the zone of collision. Reduction of space in the area of Caucasian-Arabian syntaxis, which occurred during the Late Cenozoic, reached 400 km; such shortening in absence of subduction was apparently achieved mainly due to

    Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a poor prognosis. A number of studies reported the association between MUC5B promoter polymorphism rs35705950 and IPF, but substantial inconsistent findings were observed and the strength of association remains unclear.The aim of the study was to investigate the association between rs35705950 and IPF in different ethnic populations.PubMed, EMBASE, Web of Science, and CENTRAL were searched from their inception to April 15, 2015. Allelic and phenotypic comparisons were conducted separately, as were comparisons in Caucasian and Asian populations. A meta-analysis with trial sequential analysis was conducted.Nine studies presented in 7 full-text articles were included, encompassing 2733 IPF patients and 5044 controls. Six studies were carried out in the Caucasian population, and 3 in the Asian population. Minor T allele was associated with an increased risk of IPF compared with G allele (odds ratio [OR] 4.85, 95% confidence interval [CI] 3.79-6.21, P = 5.88 × 10), as were TG and TT genotypes compared with GG genotype (TG vs GG: OR 6.20, 95% CI 5.14-7.48, P = 1.70 × 10; TT vs GG: OR 11.29, 95% CI 5.69-22.40, P = 4.22 × 10), in an allele dose-dependent manner. These observations were confirmed in trial sequential analysis in both populations. The strength of association was more remarkable in the Caucasian population than in the Asian population, and no homozygous TT genotype was detected in the Asian population in our study.Our study revealed strong association between the MUC5B promoter rs35705950 polymorphism and the risk of IPF. The strength of association between rs35705950 minor T allele and IPF susceptibility was particularly evident in the Caucasian population, and milder but still significant in the Asian population.

    Breast cancer is the most common form of cancer in American women across most ethnic groups. Although the psychosocial impact of breast cancer is being studied, there is little information on women from diverse ethnic and socioeconomic backgrounds. We conducted a qualitative study with breast cancer survivors (BCS) of various ethnicities. A total of 102 BCS participated in focus group interviews (24 African Americans, 34 Asians, 26 Latinas and 18 Caucasians); 20 health professionals participated in key informant interviews. Important ethnic differences in type of treatment were noted, Asians and Latinas were more likely to receive mastectomies and African American BCS were least likely to receive adjuvant therapies, including radiation and chemotherapy. These BCS enjoyed a fairly good overall health-related quality of life (HRQOL) with some persistent concerns. The prevailing concerns among all women included overall health, moderate physical concerns, cancer recurrence or metastases, psychosocial concerns related to worry about children and burdening the family, and body image and sexual health concerns. Additional challenges included: lack of knowledge about breast cancer; medical care issues such as insurance, cost and amount of time spent with physician; cultural sensitivity of providers, language barriers, cultural factors related to beliefs about illness, gender role and family obligations (e.g. self-sacrifice). These BCS, particularly the women of color, voiced that their spiritual beliefs and practices are central to their coping. This study accomplishes two goals; it adds to the sparse literature concerning the psychosocial sequelae of breast cancer among women of color, and it increases our knowledge of specific cultural influences (e.g. dietary practices, coping) and socio-ecological factors on HRQOL. More importantly, the study addressed areas that have not been studied before, specifically, an in-depth study on BCS QOL comparing multiple ethnic groups

    The practice of female genital mutilation predates the founding of both Christianity and Islam. Though largely confined among Muslims, the operation is also practiced in some Christian communities in Africa such that female genital mutilation takes place in various forms in more than twenty African countries, Oman, Yemen, the United Arab Emirates, and by some Muslims in Malaysia and Indonesia. In recent decades, ethnic groups which practice female genital mutilation have immigrated to Britain. The main groups are from Eritrea, Ethiopia, Somalia, and Yemen. In their own countries, an estimated 80% of women have had the operation. Female genital mutilation has been illegal in Britain since 1985, but it is practiced illegally or children are sent abroad to undergo the operation typically at age 7-9 years. It is a form of child abuse which poses special problems. The authors review the history of female genital mutilation and describe its medical complications. Assuming that the size of the population in Britain of ethnic groups which practice or favor female genital mutilation remains more or less unchanged, adaptation and acculturation will probably cause the practice to die out within a few generations. Meanwhile, there is much to be done. A conspiracy of silence exists in medical circles as well as widespread ignorance. Moreover, none of a number of well-known obstetric and pediatric textbooks mentions female genital mutilation, while the National Society for the Prevention of Cruelty to Children has neither information nor instructional material. It is high time that the problem was more widely and openly discussed. PMID:7787654

    This paper analyses passages of the Hippocratic Corpus, of Aristotle and Galen about oneirogmòs, spermatic emission during sleep, referring specifically to women. Into the Hippocratic texts there is only one gynaecological case among many cases about males: for them this nocturnal emission is symptom of dangerous illness and De genitura gives a causal explanation of such phaenomenon. Instead, in Aristotle and Galen erotic dream is evidence for or against emission of female seed and female contribution to generation. As the argument ofHistoria animalium book X shows clear theoretical differences from that of De generatione animalium, the topic of erotic dream also concerns issues of authenticity. PMID:20695404

    Fruit and vegetables contain carotenoid pigments, which accumulate in human skin, contributing to its yellowness. This effect has a beneficial impact on appearance. The aim was to evaluate associations between diet (fruit, vegetable and dietary carotenoid intakes) and skin color in young women. Ninety-one Caucasian women (Median and Interquartile Range (IQR) age 22.1 (18.1–29.1) years, BMI 22.9 (18.5–31.9) kg/m2) were recruited from the Hunter region (Australia). Fruit, vegetable and dietary carotenoid intakes were estimated by a validated food frequency questionnaire. Skin color was measured at nine body locations (sun exposed and unexposed sites) using spectrophotometry. Multiple linear regression was used to assess the relationship between fruit and vegetable intakes and skin yellowness adjusting for known confounders. Higher combined fruit and vegetable intakes (β = 0.8, p = 0.017) were associated with higher overall skin yellowness values. Higher fruit combined fruit and vegetable intakes (β = 1.0, p = 0.004) were associated with increased unexposed skin yellowness. Combined fruit and vegetables plus dietary carotenoid intakes contribute to skin yellowness in young Caucasian women. Evaluation of interventions using improvements in appearance as an incentive for increasing fruit and vegetable consumption in young women is warranted. PMID:26184306

    Evaluation of the frequency index for mtDNA particular sequences in the Caucasian population is crucial for forensic practice. There are two hypervariable regions in the mtDNA D-loop, HV1 and HV2. Both of them, 610 bp altogether, were sequenced, 342 bp from the hypervariable region HV1 (16024-16365) and 268 bp from the hypervariable region HV2 (73-340). We have analyzed 374 randomly selected non-related individuals of th e Caucasian population and 192 individuals of the Roma subpopulation living in Slovakia. The main goals of the work were to introduce and standardize methods of analysis of variability of the HV1 and HV2 regions of mtDNA for forensic use; to characterize the variability of mtDNA in the Slovakian population taking into account the subpopulations; classification of mtDNA profiles into haplotype groups, and comparison with other haplotype groups in Europe in the frame of phylogenetic studies.

    The purpose of this study was to determine differences in genotype distribution and allele frequency of urokinase and vitamin D receptor (VDR) single nucleotide polymorphisms (SNPs) between first-stone formers, recurrent stone formers, and controls in a Caucasian population. A total of 86 first-stone formers, 78 recurrent stone formers, and 167 controls were included. Urokinase and VDR SNPs were tested by gene amplification followed by ApaL1 and Taq1 endonuclease digestion, respectively. Baseline variables, genotype, and allele frequencies were compared between the three groups, using descriptive statistics. Adjusted odds ratios were calculated to estimate the risk for recurrent urolithiasis associated with genotypes. We found that differences in the distribution of ApaL1 SNP and Taq1 SNP genotypes were statistically different between recurrent stone formers and first-stone formers, and between recurrent stone formers and controls. Allele frequency analysis showed that the T allele for ApaL1 SNP and the C allele for Taq1 SNP were significantly associated with recurrent urolithiasis. For Taq1 SNP, logistic regression analysis showed that the C/C genotype was associated with a more than threefold higher risk for recurrent urolithiasis. We conclude that ApaL1 and Taq1 SNPs of the urokinase and VDR genes are associated with recurrent urolithiasis in a Caucasian population. PMID:26275878

    Racial and ethnic disparities in delinquency among child welfare-involved youth are well documented. However, less is known about the mechanisms through which these disparities occur. This study explores the extent to which sets of variables predict the occurrence of juvenile delinquency and whether race/ethnicity moderates the strength of the relationships between (1) social, emotional, and behavioral (SEB) problems and delinquency and (2) mental health service use and delinquency. We used a nationally representative sample of 727 African American, Caucasian, and Latino youth between the ages of 12-17 who were referred to the child welfare system. Controlling for age, gender, placement instability, maltreatment history, poverty, and urbanicity, linear regression analyses revealed that African American and Latino youth engaged in more delinquent acts than Caucasian youth did. However, service use decreased the likelihood of engaging in more delinquent acts for African Americans. Additional efforts are needed to illuminate and address the contextual and organizational barriers to delivering effective mental health services as a strategy to reduce racial disparities in delinquent behavior.

    The presentation, natural history, clinical outcomes, and response to therapy in patients with heart failure differ in some ways across populations. Women, older adults, and non-Caucasian racial or ethnic groups compose a substantial proportion of the overall heart failure population, but they have typically been underrepresented in clinical trials. As a result, uncertainty exists about the efficacy of some guideline-directed medical therapies and devices in specific populations, which may result in the under- or overtreatment of these patients. Even when guideline-based treatments are prescribed, socioeconomic, physical, or psychologic factors may affect non-Caucasian and older adult patient groups to a different extent and affect the application, effectiveness, and tolerability of these therapies. Individualized therapy based on tailored biology (genetics, proteomics, metabolomics), socioeconomic and cultural considerations, and individual goals and preferences may be the optimal approach for managing diverse patients. This comprehensive approach to personalized medicine is evolving, but in the interim, the scientific community should continue efforts focused on intensifying research in special populations, prescribing guideline-directed medical therapy unless contraindicated, and implementing evidence-based strategies including patient and family education and multidisciplinary team care in the management of patients.

    Allele distributions for 13 tetrameric short tandem repeat (STR) loci, CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, and D21S11, were determined in African American, United States Caucasian, Hispanic, Bahamian, Jamaican, and Trinidadian sample populations. There was little evidence for departures from Hardy-Weinberg expectations (HWE) in any of the populations. Based on the exact test, the loci that departed significantly from HWE are: D21S11 (p = 0.010, Bahamians); CSF1PO (p = 0.014, Trinidadians); TPOX (p = 0.011, Jamaicans and p = 0.035, U.S. Caucasians); and D16S539 (p = 0.043, Bahamians). After employing the Bonferroni correction for the number of loci analyzed (i.e., 13 loci per database), these observations are not likely to be significant. There is little evidence for association of alleles between the loci in these databases. The allelic frequency data are similar to other comparable data within the same major population group.

    Ala100Thr has been suggested to be a Caucasian genetic marker on the FY*B allele. As the Brazilian population has arisen from miscegenation among Portuguese, Africans, and Indians, this mutation could possibly be found in Euro- and Afro-Brazilians, or in Brazilian Indians. Fifty-three related individuals and a random sample of 100 subjects from the Brazilian population were investigated using the polymerase chain reaction and four restriction fragment length polymorphisms. Confirming the working hypothesis, among the related individuals three Afro-Brazilians (two of them a mother and daughter) and a woman of Amerindian descent had the Ala100Thr mutation on the FY*B allele. Five non-related Euro-Brazilians also carried the mutation. All nine individuals presented the Fy(a-b+) phenotype. We conclude that the Ala100Thr mutation can occur in populations other than Caucasians and that this mutation does not affect Duffy expression on red blood cells. Gene frequencies for this allele in the non-related individuals were in agreement with those of other populations. The Duffy frequencies of two Amerindian tribes were also investigated.

    Propionic acidemia is an inherited disorder of organic acid metabolism that is caused by deficiency of propionly-CoA carboxylase. Affected patients fall into two complementation groups, pccA and pccBC (subgroups B, C, and BC), resulting from deficiency of the nonidentical {alpha} and {beta} subunits of PCC, respectively. The authors have detected an unusual insertion/deletion in the DNA of patients from the pccBC and pccC subgroups that replaces 14 nucleotides in the coding sequence of the {beta} subunit with 12 nucleotides unrelated to this region of the gene. Among 14 unrelated Caucasian patients in the pccBc complementation group, this unique mutation was found in 8 of 28 mutant alleles examined. Mutant allele-specific oligonucleotide hybridization to amplified genomic DNAs revealed that the inserted 12 nucleotides do not originate in an {approx}1000-bp region around the mutation. In the course of the investigation, they identified another mutation in the same exon: a 3-bp in-frame deletion that eliminates one of two isoleucine codons immediately preceding the Msp I site. Two unrelated patients were compound heterozygotes for this single-codon deletion and for the insertion/deletion described above. They conclude that either there is a propensity for the PCC {beta}-subunit gene to undergo mutations of this sort at this position or, more likely, the mutations in all of the involved Caucasian patients have a common origin in preceding generations.

    Fruit and vegetables contain carotenoid pigments, which accumulate in human skin, contributing to its yellowness. This effect has a beneficial impact on appearance. The aim was to evaluate associations between diet (fruit, vegetable and dietary carotenoid intakes) and skin color in young women. Ninety-one Caucasian women (Median and Interquartile Range (IQR) age 22.1 (18.1-29.1) years, BMI 22.9 (18.5-31.9) kg/m2) were recruited from the Hunter region (Australia). Fruit, vegetable and dietary carotenoid intakes were estimated by a validated food frequency questionnaire. Skin color was measured at nine body locations (sun exposed and unexposed sites) using spectrophotometry. Multiple linear regression was used to assess the relationship between fruit and vegetable intakes and skin yellowness adjusting for known confounders. Higher combined fruit and vegetable intakes (β = 0.8, p = 0.017) were associated with higher overall skin yellowness values. Higher fruit combined fruit and vegetable intakes (β = 1.0, p = 0.004) were associated with increased unexposed skin yellowness. Combined fruit and vegetables plus dietary carotenoid intakes contribute to skin yellowness in young Caucasian women. Evaluation of interventions using improvements in appearance as an incentive for increasing fruit and vegetable consumption in young women is warranted. PMID:26184306

    Aim Aim of this study was to compare the volume and the shape of mandibular condyles in a Caucasian young adult population, with different skeletal pattern. Material and methods 200 Caucasian patients (15–30 years old, 95 male and 105 females) were classified in three groups on the base of ANB angle: skeletal class I (65 patients), skeletal class II (70 patients) and skeletal class III (65 patients). Left and right TMJs of each subject were evaluated independently with CBCT (Iluma). TMJ evaluation included: condylar volume; condylar area; morphological index (MI). Condylar volumes were calculated by using the Mimics software. The condylar volume, the area and the morphological index (MI) were compared among the three groups, by using non-parametric tests. Results The Kruskal-Wallis test and the Mann Whitney test revealed that: no significant difference was observed in the whole sample between the right and the left condylar volume; subjects in skeletal class III showed a significantly higher condylar volume, respect to class I and class II subjects (p < 0.05); significantly lower condylar volume was observed in class II subjects, respect to class I and class III (p < 0.05). In the whole sample condylar volume (699.8 ± 63.07 mm3 in males and 663.5 ± 81.3 mm3 in females; p < 0.01) as well as condylar surface (423.24 ± 63.03 mm2 in males and 389.76 ± 61.15 mm2 in females; p < 0.01) were significantly higher in males than in females. Conclusion Skeletal class appeared to be associated to the mandibular condylar volume and to the mandibular condylar area in the Caucasian orthodontic population. PMID:23241136

  3. Knee injuries in female athletes.

    PubMed

    Hutchinson, M R; Ireland, M L

    1995-04-01

    Female athletes are at increased risk for certain sports-related injuries, particularly those involving the knee. Factors that contribute to this increased risk are the differences in sports undertaken and in gender anatomy and structure. Gender differences include baseline level of conditioning, lower extremity alignment, physiological laxity, pelvis width, tibial rotation and foot alignment. Sports like gymnastics and cheerleading create a noncontact environment, but can result in significant knee injuries. In quick stopping and cutting sports, females have an increased incidence of anterior cruciate ligament (ACL) injury by noncontact mechanisms. Patellofemoral (PF) disorders are also very common in female athletes. Awareness of these facts helps the sports medicine professional make an accurate diagnosis and institute earlier treatment-focused rehabilitation with or without surgery. Further prospective and retrospective research is needed in areas of epidemiology, mechanisms, severity and types of knee injuries. The goal is to lessen the severity of certain knee injuries and to prevent others. PMID:7604201

    2016-01-01

    Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility. PMID:27123194

  5. Female circumcision: Limiting the harm

    Objective: To review the strength of evidence that links many health hazards to female genital cutting. Material and methods: Literature search in Medline/Pubmed and Google scholar. Results: Female genital cutting is still practiced secretly in both underdeveloped and developed countries due to prevailing strong traditional beliefs. There is insufficient evidence to support the claims that genital cutting is a harmful procedure if performed by experienced personnel in a suitable theatre with facilities for pain control and anesthesia. Cutting, however, is advised not to go beyond type I. Conclusion: Law makers around the globe are invited to review the legal situation in relation to female genital cutting. Proper counseling of parents about possible risks is a must in order to make informed decision about circumcising their daughters. The procedure should be offered to parents who insist on it; otherwise, they will do it illegally, exposing their daughters to possible complications. PMID:24627762

    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values. PMID:12158005

    For a long time, only one public university in Uganda had a department of physics. Several women graduated from this department, but not many showed much interest in pursuing higher degrees in physics. Currently, there are five public universities in Uganda with departments of physics, and there has been an increase in the number of female graduates in physics. At the same time, the number of women pursuing higher degrees in physics has increased, and the universities have registered an increase in female physics lecturers.

    Increased sensitivity to cold may be a predictor of persistent pain, but cold pain threshold is often viewed as unreliable. This study aimed to determine the within-subject reliability and between-subject variance of cold response, measured comprehensively as cold pain threshold plus pain intensity and sensation quality at threshold. A test-retest design was used over three sessions, one day apart. Response to cold was assessed at four sites (thenar eminence, volar forearm, tibialis anterior, plantar foot). Cold pain threshold was measured using a Medoc thermode and standard method of limits. Intensity of pain at threshold was rated using a 10cm visual analogue scale. Quality of sensation at threshold was quantified with indices calculated from subjects' selection of descriptors from a standard McGill Pain Questionnaire. Within-subject reliability for each measure was calculated with intra-class correlation coefficients and between-subject variance was evaluated as group coefficient of variation percentage (CV%). Gender and site comparisons were also made. Forty-five healthy adults participated: 20 male, 25 female; mean age 29 (range 18-56) years. All measures at all four test sites showed high within-subject reliability: cold pain thresholds r = 0.92-0.95; pain rating r = 0.93-0.97; McGill pain quality indices r = 0.87-0.85. In contrast, all measures showed wide between-subject variance (CV% between 51.4% and 92.5%). Upper limb sites were consistently more sensitive than lower limb sites, but equally reliable. Females showed elevated cold pain thresholds, although similar pain intensity and quality to males. Females were also more reliable and showed lower variance for all measures. Thus, although there was clear population variation, response to cold for healthy individuals was found to be highly reliable, whether measured as pain threshold, pain intensity or sensation quality. A comprehensive approach to cold response testing therefore may add validity and

    The current 5-year accelerated longitudinal investigation modeled the developmental trajectories of aggressive behaviors in 10,107 predominantly minority (>70%; African American, American Indian, Asian American, and Hispanic) children and early adolescents (Kindergarten through 8th grade, 49% female youth) from lower to lower-middle socioeconomic strata. Based on a two-part latent growth model, findings suggest that the probability and frequency of aggressive behavior use decreases slightly (linear) through the elementary school years and then increases as children move into middle school (quadratic). Though mean level differences were found across ethnic and racial groups, socioeconomic strata, and particularly by sex at initial status, rates of change over time across all groups were invariant. Findings suggest that potential socialization differences, if any, occur pre-Kindergarten in all groups. PMID:17643190

    2015-10-01

    In certain populations, female Japanese macaques (Macaca fuscata) mount both males and females. Vasey (2007) proposed that female-female sexual mounting in Japanese macaques may be a neutral evolutionary by-product of a purported adaptation, namely, female-male mounting. In this study, we aim to further examine the proposed link between female-male and female-female mounting in Japanese macaques by comparing the structural characteristics that define both forms of mounting. We do so using Eshkol-Wachman Movement Notation (EWMN), a globographic reference system that can be used to describe the position of body segments. No significant differences were observed in the female mounters' positioning of eight different body segments (i.e., lower torso, mid-torso, upper torso, upper arm, lower arm, upper leg, lower leg, and foot) during female-male and female-female mounting. This finding lends support to the conclusion that female-female and female-male mounting are structurally, and thus, evolutionarily, related. PMID:26232264

    In this review of published findings on human immunodeficiency virus (HIV) infection and risk factors among female sex workers, we summarize the results of seroprevalence studies in different countries and discuss the different patterns of transmission among such workers in various geographical regions. The highest rates of HIV infection occur in sub-Saharan Africa, where the widespread existence of sexually transmitted diseases may play an important role in sustaining transmission. In Europe and North America injecting drug use continues to be the major factor associated with HIV infection among female sex workers, while in Latin America and parts of Asia there is a more mixed pattern of heterosexual and parenteral transmission from injecting drug use. Reviewed also are studies of the risk factors associated with HIV infection among female sex workers, such as drug use, sexual behaviour, the presence of sexually transmitted diseases, and condom use; in addition, we comment on some studies of the clients of sex workers. Finally, we propose directions that future research in this area might take and discuss various interventions that need to be undertaken to reduce HIV transmission among female sex workers.

  5. The effect of parental education, prior achievement, self-efficacy, goal orientation, and effort on undergraduate science performance of Latinos and Caucasians

    NASA Astrophysics Data System (ADS)

    Stansbury, Sydney Lynn

    Compared with majority students, underrepresented minorities have demonstrated weaker undergraduate science performance. Previous research has attributed the weaker performance to socioeconomic factors that influence poorer precollege preparation. Studies also have found that, compared with majority students, underrepresented minorities are less confident about their science skills and more interested in extrinsic rewards of science careers. Social Cognitive Theory posits that low self-efficacy coupled with high extrinsic goal orientation diminishes cognitive engagement, resulting in weak performance. Applying motivational characteristics of underrepresented minority students to a Social Cognitive Model may explain why their performance is weaker than that of Caucasians. Thus, the purpose of this study was to investigate the degree to which motivation variables account for the difference between underrepresented minority and majority students' undergraduate science performance. The study was conducted at a large, predominantly Caucasian, private university located in an urban setting in the Southwest. Two hundred twenty-two students--154 Caucasians and 68 Latinos--enrolled in a general chemistry course participated. Students were administered the Motivation for Learning Questionnaire, designed specifically for this study, consisting of scales measuring the following variables: ethnicity, level of parental education, and effort exertion; self-efficacy, effort regulation, intrinsic goal orientation, and extrinsic goal orientation, measures from the Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991); and ability orientation, a measure from the Patterns of Adaptive Learning Survey (Midgley, Maehr, & Urdan, 1995). Financial aid information, chemistry and math placement test scores, and chemistry grades were obtained from other on-campus departments.

Methods Ten race- and sex-stratified nominal groups were conducted, oversampling for African-Americans and women with gout. Patients presented, discussed, combined and rank-ordered their concerns. Results A total of 62 patients with mean age 65.1 years, 60% men, 64% African-American, participated in 10 nominal groups: African-American men (n = 23; 3 groups); African-American women (n = 18; 3 groups); Caucasian men (n = 15; 3 groups); and Caucasian women (n = 6; 1 group). The most frequently cited high-ranked concerns among the ten nominal groups were: (1) effect of gout flare on daily activities (n = 10 groups); (2) work disability (n = 8 groups); (3) severe pain (n = 8 groups); (4) joint swelling and tenderness (n = 6 groups); (5) food restrictions (n = 6 groups); (6) medication related issues (n = 6 groups); (7) dependency on family and others (n = 5 groups); (8) emotional Impact (n = 5 groups); (9) interference with sexual function (n = 4 groups); (10) difficulty with shoes (n = 4 groups); and (11) sleep disruption (n = 4 groups). Compared with men, women ranked the following concerns high more often: problems with shoes (n = 4 versus n = 0 groups); dependency (n = 3 versus n = 2 groups); and joint/limb deformity (n = 2 versus n = 0 group). Compared with Caucasians, African-Americans ranked the following concerns high more often: dietary restrictions (n = 6 versus n = 0 groups); severe pain (n = 6 versus n = 2 groups); gout bringing the day to a “halt” (n = 2 versus n = 0 group); effect on emotional health (n = 4 versus n = 1 groups); and the need for canes/crutches during flares (n = 2 versus n = 0 group). Conclusions Gout has a significant impact on a patient’s QOL. Important differences in the

    Interview and descriptive methods were used to investigate the stressors and coping strategies of academically successful African American female baccalaureate nursing students (N = 23) in the three predominantly Caucasian universities in South Carolina. The study addressed three questions: 1) What are major stressors for African American female students? 2) Which coping strategies do these students use? and 3) Which coping strategies do these students find to be most successful? Major stressors identified, both by priority and frequency of occurrence, were academic in nature, followed in descending order by environmental, financial, interpersonal, and personal stressors. Coping strategies used with the greatest regularity and success were active coping (taking action to remove or circumvent the stressor), seeking social support for instrumental reasons (seeking assistance, information, or advice about what to do from someone in a position to help), and seeking social support for emotional reasons (getting sympathy or emotional support from someone). Behavioral disengagement, denial, and alcohol-drug disengagement were reported to be unsuccessful coping strategies in the majority of instances. PMID:9476729

    The typing of single nucleotide polymorphisms (SNPs) located throughout the human mitochondrial genome assists in resolving individuals with an identical HV1/HV2 haplotype. A set of 11 sites which were selected for distinguishing individuals of a common Western European Caucasian HV1/HV2 mitotype was incorporated into a single base extension (SBE) assay. The assay was optimized for multiplex detection of sequence polymorphisms at positions 3010, 4793, 10211, 5004, 7028, 7202, 16519, 12858, 4580, 477, and 14470 in the mitochondrial genome. PCR primers were designed to allow for multiplex amplification of unique regions in the mitochondrial genome followed by an 11-plex SBE reaction using the SNaPshot(®) reagent kit. Separation and detection can be accomplished with a capillary-based electrophoresis platform commonly found in most forensic laboratories. PMID:22139659

    The search for genes with a positive influence on physical fitness is a difficult process. Physical fitness is a trait determined by multiple genes, and its genetic basis is then modified by numerous environmental factors. The present study examines the effects of the polymorphism of creatine kinase (CKM) gene on VO2max – a physiological index of aerobic capacity of high heritability. The study sample consisted of 154 men and 85 women, who were students of the University School of Physical Education in Poznań and athletes practicing various sports, including members of the Polish national team. The study revealed a positive effect of a rare G (NcoI−) allele of the CKM gene on maximal oxygen uptake in Caucasian women practicing sports requiring aerobic and anaerobic exercise metabolism. Also a tendency was noted in individuals with NcoI−/− (GG) and NcoI−/+ (GA) genotypes to reach higher VO2max levels. PMID:24511349

    Objective Hallux valgus (HV) affects ~36% of Caucasian adults. Although considered highly heritable, the underlying genetic determinants are unclear. We conducted the first genome-wide association study (GWAS) aimed to identify genetic variants associated with HV. Methods HV was assessed in 3 Caucasian cohorts (n=2,263, n=915, and n=1,231 participants, respectively). In each cohort, a GWAS was conducted using 2.5M imputed single nucleotide polymorphisms (SNPs). Mixed-effect regression with the additive genetic model adjusted for age, sex, weight and within-family correlations was used for both sex-specific and combined analyses. To combine GWAS results across cohorts, fixed-effect inverse-variance meta-analyses were used. Following meta-analyses, top-associated findings were also examined in an African American cohort (n=327). Results The proportion of HV variance explained by genome-wide genotyped SNPs was 50% in men and 48% in women. A higher proportion of genetic determinants of HV was sex-specific. The most significantly associated SNP in men was rs9675316 located on chr17q23-a24 near the AXIN2 gene (p=5.46×10−7); the most significantly associated SNP in women was rs7996797 located on chr13q14.1-q14.2 near the ESD gene (p=7.21×10−7). Genome-wide significant SNP-by-sex interaction was found for SNP rs1563374 located on chr11p15.1 near the MRGPRX3 gene (interaction p-value =4.1×10−9). The association signals diminished when combining men and women. Conclusion Findings suggest that the potential pathophysiological mechanisms of HV are complex and strongly underlined by sex-specific interactions. The identified genetic variants imply contribution of biological pathways observed in osteoarthritis as well as new pathways, influencing skeletal development and inflammation. PMID:26337638

    High-risk populations exhibit early transformation of localized prostate cancer (CaP) disease to metastasis which results in the mortality of such patients. The paucity of knowledge about the molecular mechanism involved in acquiring of metastatic behavior by primary tumor cells and non-availability of reliable phenotype-discriminating biomarkers are stumbling blocks in the management of CaP disease. Here, we determine the role and translational relevance of ROBO1 (an organogenesis-associated gene) in human CaP. Employing CaP-progression models and prostatic tissues of Caucasian and African-American patients, we show that ROBO1 expression is localized to cell-membrane and significantly lost in primary and metastatic tumors. While Caucasians exhibited similar ROBO1 levels in primary and metastatic phenotype, a significant difference was observed between tumor phenotypes in African-Americans. Epigenetic assays identified promoter methylation of ROBO1 specific to African-American metastatic CaP cells. Using African-American CaP models for further studies, we show that ROBO1 negatively regulates motility and invasiveness of primary CaP cells, and its loss causes these cells to acquire invasive trait. To understand the underlying mechanism, we employed ROBO1-expressing/ROBO1-C2C3-mutant constructs, immunoprecipitation, confocal-microscopy and luciferase-reporter techniques. We show that ROBO1 through its interaction with DOCK1 (at SH3-SH2-domain) controls the Rac-activation. However, loss of ROBO1 results in Rac1-activation which in turn causes E-Cadherin/β-catenin cytoskeleton destabilization and induction of cell migration. We suggest that ROBO1 is a predictive biomarker that has potential to discriminate among CaP types, and could be exploited as a molecular target to inhibit the progression of disease as well as treat metastasis in high-risk populations such as African-Americans.

    Purpose. Genetically complex disorders, such as primary open angle glaucoma (POAG), may include highly heritable quantitative traits as part of the overall phenotype, and mapping genes influencing the related quantitative traits may effectively identify genetic risk factors predisposing to the complex disease. Recent studies have identified SNPs associated with optic nerve area and vertical cup-to-disc ratio (VCDR). The purpose of this study was to evaluate the association between these SNPs and POAG in a US Caucasian case-control sample. Methods. Five SNPs previously associated with optic disc area, or VCDR, were genotyped in 539 POAG cases and 336 controls. Genotype data were analyzed for single SNP associations and SNP interactions with VCDR and POAG. Results. SNPs associated with VCDR rs1063192 (CDKN2B) and rs10483727 (SIX1/SIX6) were also associated with POAG (P = 0.0006 and P = 0.0043 for rs1063192 and rs10483727, respectively). rs1063192, associated with smaller VCDR, had a protective effect (odds ratio [OR] = 0.73; 95% confidence interval [CI], 0.58–0.90), whereas rs10483727, associated with larger VCDR, increased POAG risk (OR = 1.33; 95% CI, 1.08–1.65). POAG risk associated with increased VCDR was significantly influenced by the C allele of rs1900004 (ATOH7), associated with increased optic nerve area (P-interaction = 0.025; OR = 1.89; 95% CI, 1.22–2.94). Conclusions. Genetic variants influencing VCDR are associated with POAG in a US Caucasian population. Variants associated with optic nerve area are not independently associated with disease but can influence the effects of VCDR variants suggesting that increased optic disc area can significantly contribute to POAG risk when coupled with risk factors controlling VCDR.

    To study vitamin D (25OH D3) in relation to (i) microbial translocation (ii) systemic inflammation and (iii) blood lipid markers, in Caucasian, well-controlled HIV patients and healthy controls, plasma and serum samples from n = 97 male, HIV patients on HAART with immeasurable viral load (<20 copies/ml) since median 6.5 years and no concurrent inflammatory or infectious disease and n = 30 healthy controls were analysed for (i) LPS; (ii) sCD14, hsCRP, IL-4, IL-6, IL-10, IL-17, MCP-1 and IFN-γ; as well as (iii) blood lipids. Vitamin D levels were similarly distributed and equally low in both HIV patients and controls. There was no association between vitamin D levels and markers of microbial translocation, systemic inflammation or dyslipidemia. LPS levels were similar in both groups but HIV patients expressed higher levels of sCD14 and hsCRP, with HIV as an independent risk factor. HIV patients had higher cholesterol and Apo B levels. Notably, more HIV patients smoked and smoking was associated with lower vitamin D levels. In conclusion; these well-treated Caucasian HIV patients had similar vitamin D levels as healthy controls. However, despite perfect virological control, they exhibited slightly increased inflammatory markers and disturbed blood lipids. However, neither of these parameters were associated with low vitamin D levels but appeared to be linked to the HIV-disease per se. Thus, the rationale for vitamin D substitution as a way to improve microbial translocation and systemic inflammation is not fully supported in this HIV population. PMID:25833795

    Objective The objective of this study was to explore the decision-making processes and associated barriers and enablers that determine access and use of healthcare services in Arabic-speaking and English-speaking Caucasian patients with diabetes in Australia. Study setting and design Face-to-face semistructured individual interviews and group interviews were conducted at various healthcare settings—diabetes outpatient clinics in 2 tertiary referral hospitals, 6 primary care practices and 10 community centres in Melbourne, Australia. Participants A total of 100 participants with type 2 diabetes mellitus were recruited into 2 groups: 60 Arabic-speaking and 40 English-speaking Caucasian. Data collection Interviews were audio-taped, translated into English when necessary, transcribed and coded thematically. Sociodemographic and clinical information was gathered using a self-completed questionnaire and medical records. Principal findings Only Arabic-speaking migrants intentionally delayed access to healthcare services when obvious signs of diabetes were experienced, missing opportunities to detect diabetes at an early stage. Four major barriers and enablers to healthcare access and use were identified: influence of significant other(s), unique sociocultural and religious beliefs, experiences with healthcare providers and lack of knowledge about healthcare services. Compared with Arabic-speaking migrants, English-speaking participants had no reluctance to access and use medical services when signs of ill-health appeared; their treatment-seeking behaviours were straightforward. Conclusions Arabic-speaking migrants appear to intentionally delay access to medical services even when symptomatic. Four barriers to health services access have been identified. Tailored interventions must be developed for Arabic-speaking migrants to improve access to available health services, facilitate timely diagnosis of diabetes and ultimately to improve glycaemic control.

    Background Breast cancer susceptibility may be modulated partly through polymorphisms in oxidative enzymes, one of which is myeloperoxidase (MPO). Association of the low transcription activity variant allele A in the G463A polymorphism has been investigated for its association with breast cancer risk, considering the modifying effects of menopausal status and antioxidant intake levels of cases and controls. Methodology/Principal Findings To obtain a more precise estimate of association using the odds ratio (OR), we performed a meta-analysis of 2,975 cases and 3,427 controls from three published articles of Caucasian populations living in the United States. Heterogeneity among studies was tested and sensitivity analysis was applied. The lower transcriptional activity AA genotype of MPO in the pre-menopausal population showed significantly reduced risk (OR 0.56–0.57, p = 0.03) in contrast to their post-menopausal counterparts which showed non-significant increased risk (OR 1.14; p = 0.34–0.36). High intake of antioxidants (OR 0.67–0.86, p = 0.04–0.05) and carotenoids (OR 0.68–0.86, p = 0.03–0.05) conferred significant protection in the women. Stratified by menopausal status, this effect was observed in pre-menopausal women especially those whose antioxidant intake was high (OR 0.42–0.69, p = 0.04). In post-menopausal women, effect of low intake elicited susceptibility (OR 1.19–1.67, p = 0.07–0.17) to breast cancer. Conclusions/Significance Based on a homogeneous Caucasian population, the MPO G463A polymorphism places post-menopausal women at risk for breast cancer, where this effect is modified by diet.

    The MC1R gene is a key regulator of skin pigmentation. We aimed to evaluate the association between MC1R variants and the risk of sporadic cutaneous melanoma (CM) within the M-SKIP project, an international pooled-analysis on MC1R, skin cancer and phenotypic characteristics. Data included 5,160 cases and 12,119 controls from 17 studies. We calculated a Summary Odds Ratio (SOR) for the association of each of the nine most studied MC1R variants and of variants combined with CM by using random-effects models. Stratified analysis by phenotypic characteristics were also performed. Melanoma risk increased with presence of any of the main MC1R variants: the SOR for each variant ranged from 1.47 (95%CI: 1.17–1.84) for V60L to 2.74 (1.53–4.89) for D84E. Carriers of any MC1R variant had a 66% higher risk of developing melanoma compared to wild-type subjects (SOR; 95%CI: 1.66; 1.41–1.96), and the risk attributable to MC1R variants was 28%. When taking into account phenotypic characteristics, we found that MC1R–associated melanoma risk increased only for darker-pigmented Caucasians: SOR (95%CI) was 3.14 (2.06–4.80) for subjects with no freckles, no red hair and skin type III/IV. Our study documents the important role of all the main MC1R variants in sporadic CM and suggests that they have a direct effect on melanoma risk, independently on the phenotypic characteristics of carriers. This is of particular importance for assessing preventive strategies, which may be directed to darker-pigmented Caucasians with MC1R variants as well as to lightly-pigmented, fair-skinned subjects.

    Telomere dysfunction is a crucial event in malignant transformation and tumorigenesis. Telomere length in peripheral blood leukocytes has been associated with lung cancer risk, but the relationship has remained controversial. In this study, we investigated whether the association might be confounded by study of different histological subtypes of lung cancer. We measured relative telomere lengths in patients in a large case-control study of lung cancer and performed stratified analyses according to the two major histological subtypes (adenocarcinoma [AC] and squamous cell carcinoma [SCC]). Notably, AC patients had longer telomeres than controls, whereas SCC patients had shorter telomeres compared to controls. Long telomeres were associated with increased risk of AC, with the highest risk associated with female sex, younger age (<60 years) and lighter smoking (<30 pack-years). In contrast, long telomeres were protective against SCC, particularly in male patients. Our results extend the concept that telomere length affects risk of lung cancer in a manner that differs with histological subtype. PMID:24618342

    This study examines women's social representations of female orgasm. Fifty semi-structured interviews were conducted with British women. The data were thematically analysed and compared with the content of female orgasm-related writing in two women's magazines over a 30-year period. The results indicate that orgasm is deemed the goal of sex with emphasis on its physiological dimension. However, the women and the magazines graft onto this scientifically driven representation the importance of relational and emotive aspects of orgasm. For the women, particularly those who experience themselves as having problems with orgasm, the scientifically driven representations induce feelings of failure, but are also resisted. The findings highlight the role played by the social context in women's subjective experience of their sexual health. PMID:19129342

    Interventions for child sexual abusers should take into account their perspectives on the context of their offenses, but no descriptions of everyday life from the offender's point of view have been published. This study therefore explored female offenders' views of their strengths and challenges. Documented risk assessments of 20 female offenders were analyzed using inductive content analysis (Cavanagh, 1997; Priest, Roberts & Woods, 2002; Woods, Priest & Roberts, 2002). The Good Lives Model provided the initial coding framework and Atlas/ti software (Muhr, 1997) was used for simultaneous data collection and analysis. The content analysis yielded 999 coding decisions organized in three themes. The global theme was relationship experiences. Offenders described the quality of their relationship experiences, including their personal perspectives, intimate relationships and social lives. These descriptions have implications for treatment planning and future research with women who have molested children. PMID:18624098
