Perceived ethnic discrimination has a negative impact on health. One of the key mechanisms may be a dysregulation of stress-responsive systems. Our aims were to investigate whether (1) acute face-to-face ethnic discrimination induces a stress response, and (2) to compare long-term endocrine functioning between immigrants and nonimmigrants. 30 male Turkish immigrants living in Germany underwent an ethnic discrimination condition and a control condition in the laboratory. Perceived ethnic discrimination, stress, salivary alpha-amylase and cortisol were measured four times...

BACKGROUND: Risk factors for B-cell non-Hodgkin lymphoma (B-NHL) have not been assessed among Palestinian Arabs (PA) and Israeli Jews (IJ). METHODS: In a case-control study we investigated self-reported medical and lifestyle exposures, reporting odds ratios (ORs) and 95% confidence intervals [CIs], by ethnicity, for overall B-NHL and subtypes. RESULTS: We recruited 823 cases and 808 healthy controls. Among 307 PA/516 IJ B-NHL cases (mean age at diagnosis = 51 [±17] versus 60 [±15] years, respectively) subtype distributions differed, with diffuse large B-cell lymphoma (DLBCL) being prominent among PA (71%) compared to IJ (41%); follicular lymphoma (FL), was observed in 14% versus 28%, and marginal zone lymphoma, in 2% versus 14%, respectively...

Ulnar-mammary syndrome (UMS) is an autosomal dominant disorder resulting from TBX3 haploinsufficiency. It typically affects limb, apocrine gland, hair, tooth and genital development and shows marked intrafamilial and interfamilial variability in phenotypic expression. We report a family (twin brothers and their father) affected with UMS because of a novel TBX3 mutation. The twin brothers showed classical features of UMS, whereas their father was mildly affected. The c.1423C>T (p.Q475*) nonsense mutation in exon 6 of the TBX3 gene identified in the patients by targeted Sanger sequencing is predicted to lead to premature termination of translation...

Skin colour varies from pale white to very dark. Fitzpatrick's skin phototypes are based on the person's skin colour and its response to sun exposure in terms of burning and tanning of the skin. Fitzpatrick's type 1V-V1 is known as the skin of colour and type 1-111 is the fair or white skin. The colour of the skin and texture of the hair are the most apparent phenotype to differentiate the different races; this correlates closely with the geography and ultraviolet radiation of the sun. There are notable differences in skin disease incidence, presentation, and treatment based on skin type...

Disposal of hair wastes at landfills causes nitrate leaching to ground water, and use of the waste as fertiliser could be a viable option. This study was to determine elemental composition of major hair types in South Africa and their nitrogen (N) and phosphorus (P) release in soil. Wastes of African, White and Indian hair were obtained from local salons and analysed for carbon (C), N and sulphur (S) with the Leco CNS analyzer, and P, bases, aluminium (Al) and micronutrients, with the ICP. We also conducted an incubation study to determine changes in mineral N and P in soil...

The under-representation of ethnic minority participants, who are more likely to be socially disadvantaged in biomedical research, limits generalizability of results and reductions in health disparities. To facilitate investigations of how social disadvantage "gets under the skin," this pilot study evaluated low-intensity methods for collecting hair and saliva samples from multiethnic breast cancer survivors (N = 70) and analysis of biomarkers of chronic stress (cortisol levels) and biological age (telomere length)...

POU4F3 gene encodes a transcription factor which plays an essential role in the maturation and maintenance of hair cells in cochlea and vestibular system. Several mutations of POU4F3 have been reported to cause autosomal dominant nonsyndromic hearing loss in recent years. In this study, we describe a pathogenic nonsense mutation located in POU4F3 in a four-generation Chinese family. Target region capture sequencing was performed to search for the candidate mutations from 81 genes related to nonsyndromic hearing loss in this family...

OBJECTIVE: Hypothalamic-pituitary-adrenal (HPA) measures are crucial for research into stress and stress-related disorders. Most HPA measures fluctuate depending on diurnal rhythms and state confounders. Hair cortisol concentrations (HCC) are less susceptible to such fluctuations, but less is known about trait-like confounders. Using a community sample, we tested the relationship between HCC and a range of variables including demographic variables, hair treatment, and medication, as well as psychosocial variables, namely childhood trauma, critical life events, and depressive symptoms...

Current demographic trends in the United States highlight the growing population of those who identify as having "skin of color." As such, dermatologists must have a greater comfort level and knowledge in treating some of the unique skin and hair conditions seen in this population. Understanding the scientific basis for the evolution of skin color and hair texture is necessary in order to understand the variations in the characteristics of skin and hair seen among racial and ethnic groups. This review seeks to highlight the current scientific explanation of skin color and hair texture, with special attention to people of African descent, in an attempt to give insight into the clinical presentations of hair and skin disorders seen in this group...

PURPOSE: Young adulthood is an important period for preventing the establishment of negative health behaviors that can influence trajectories to chronic disease and early death. Given the evolving nature of educational attainment and income variation during this developmental period, identifying indicators of socioeconomic status (SES) remains a challenge. This study examines measures of subjective and objective indicators of SES to predict health risk for young adults. METHODS: This study uses data from the Truth Initiative Young Adult Cohort Study from respondents aged 18 to 34 years who completed 3 consecutive surveys between June 2011 and August 2012 (n = 2182)...

BACKGROUND: Allergic contact dermatitis after exposure to p-phenylenediamine (PPD)-containing hair dye products is a common and important clinical problem. Because there is a high rate of cross-elicitation of allergic contact dermatitis to other important hair dye products (such as p-toluene diamine and other aminophenol hair dyes) in PPD-allergic patients, safer alternative dyes with excellent hair coloring options are needed. OBJECTIVE: This study aimed to study tolerance to Me-PPD in a PPD-allergic cohort...

BACKGROUND: Ethnic differences in skin sensitivity suggest that greater emphasis be focused on understanding a product's effect in diverse populations. OBJECTIVE: The irritation and/or sensitization potential of 8 baby skin care products in Indian adults were evaluated using cumulative irritation tests (CIT) and human repeat insult patch testing (HRIPT) protocols. PATIENTS/MATERIALS/METHODS: Healthy males or females aged 18 to 65 years of Indian ethnicity were treated with each of 6 products (cream, hair oil, lotion, body wash, shampoo, and baby soap) using CIT (n = 25) and HRIPT (n = 200)...

OBJECTIVE: There is increasing evidence for weight-based discrimination against persons with obesity. This study aimed to examine the physiological impact of perceived weight discrimination on cortisol in hair, an indicator of chronic stress exposure. METHODS: Data were from 563 nonsmoking individuals with obesity (body mass index, BMI ≥30 kg/m(2) ) participating in the English Longitudinal Study of Ageing. Experiences of discrimination were reported via questionnaire, and hair cortisol concentrations were determined from the scalp-nearest 2-cm hair segment...

Acquired trichorrhexis nodosa is a common cause of hair loss for patients of all ethnicities. It is especially prevalent in black patients with tightly curled hair types and can present unique diagnostic and therapeutic challenges due to structural differences in these hair types and the combination of various hair care and styling practices that contribute to hair damage. While scalp biopsies can help rule out other etiologies of hair loss, there is a paucity of histologic findings in acquired trichorrhexis nodosa, making this primarily a clinical diagnosis...

BACKGROUND: Spontaneous preterm birth is a complex syndrome with multiple pathways interactions determining its occurrence, including genetic, immunological, physiologic, biochemical and environmental factors. Despite great worldwide efforts in preterm birth prevention, there are no recent effective therapeutic strategies able to decrease spontaneous preterm birth rates or their consequent neonatal morbidity/mortality. The Preterm SAMBA study will associate metabolomics technologies to identify clinical and metabolite predictors for preterm birth...
