Non-communicable diseases (NCDs) account for 76% of deaths in Iran and this number is on the rise, parallel to global rates. Many risk factors associated with NCDs are preventable; however it is first necessary to conduct observational studies to identify relevant risk factors, and the most appropriate approach to control them. Iran is a multi-ethnic country, therefore the Ministry of Health and Medical Education sought to launch a nationwide cohort study-the Prospective Epidemiological Research Studies in IrAN (PERSIAN)-in order to identify the most prevalent NCDs among Iranian ethnicities, and to investigate effective methods of prevention...

<p>Hair loss affects millions of men and women of all ages and ethnicities, impacting appearance, social interactions, and psycho-emotional well-being. Although a number of options are available, they are limited, carry a potential risk of side effects, and none have proven to be comprehensive for treatment of hair loss. Across the spectrum of hair loss disorders, there has long been a segmentation into distinct mechanisms, driving the main trend in current therapeutics to focus on targeting single molecules or pathways...

REVIEW
Michelle Henry
Men of all races are currently more open to requesting and undergoing treatments for a plethora of cosmetic concerns. Among the most common goals are procedures that combat the signs of aging, rejuvenate the skin, even out the color tone, address textural issues such as acne scarring, and improve hair disorders. Given the differences in cultural ideals and anatomic/physiologic differences in ethnic skin, it is important for physicians to be aware and sensitive to the nuances required when providing consultation and treating non-Caucasian men...

#4
Franz J Wortmann, Gabriele Wortmann
A deconvolution process has been developed for curves obtained by Differential Scanning Calorimetry in water for Merino wool and the main ethnic hair types. This enables estimation of the fractions of ortho- and para-type cell groups. The results also indicate that hair may contain a further, low-sulphur sub-group of ortho-type cells. The sizes of the major cell fractions are in line with expectations from microscopical investigations. The fractions are comparable for hair types and no consistent association between cell type fractions and hair curvature is observed...

Earlier puberty and menarcheal age are associated with adverse health outcomes. Reported associations of maternal adiposity with daughters' menarcheal age are inconsistent. We examined associations between maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG), and daughters' age at menarche (n = 3,935), pubarche (Tanner stage 2 for pubic hair) and thelarche (Tanner stage 2 for breast development) (n = 2,942) in the Avon Longitudinal Study of Parents and Children, a UK prospective pregnancy cohort (baseline 1991-1992)...

BACKGROUND: Non-suicidal self-injury (NSSI) is a highly prevalent and serious public health problem among adolescents worldwide. However, to date there were no studies assessing the prevalence of NSSI defined by suggested DSM-5 criteria among Chinese adolescents. We aimed to conduct a nationwide survey to explore the prevalence of and risk factors for NSSI among school-based adolescents in rural China. METHODS: A total sample of 15,623 adolescents in rural China were enrolled by using a multistage sampling method...

Little research has examined the impact of maternal lifetime trauma exposure on infant temperament. We examined associations between maternal trauma history and infant negative affectivity and modification by prenatal cortisol exposure in a sociodemographically diverse sample of mother-infant dyads. During pregnancy, mothers completed measures of lifetime trauma exposure and current stressors. Third-trimester cortisol output was assessed from maternal hair. When infants were 6 months old, mothers completed the Infant Behavior Questionnaire-Revised...

BACKGROUND: Higher socioeconomic position (SEP) has been associated with increased risk of breast cancer. Its relationship with earlier age of pubertal onset, a risk factor for breast cancer, is less clear. METHODS: We studied the relationship of SEP to pubertal onset in multiethnic cohort of 1237 girls aged 6-8 years at baseline. Girls in three U.S. cities were followed for 5-8 years with annual clinical examinations from 2004 to 2012. SEP measures were examined for associations with pubertal onset, assessed by breast budding (thelarche) and pubic hair development (adrenarche)...

Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare genetic disorder that shows a characteristic progeria phenotype. We conducted a questionnaire survey of 1173 tertiary hospitals in Japan and reviewed the academic reports, to identify the characteristics of Asian patients with classical HGPS. As a result, four Japanese patients were identified; this was estimated to account for approximately two-third of the prevalence in Japan. Three Asian patients who had definitively been diagnosed with classical HGPS were identified in the literature; in total, the clinical characteristics of seven patients were evaluated...

Ami R Zota, Bhavna Shamasunder
The obstetrics-gynecology community has issued a call to action to prevent toxic environmental chemical exposures and their threats to healthy human reproduction. Recent committee opinions recognize that vulnerable and underserved women may be impacted disproportionately by environmental chemical exposures and recommend that reproductive health professionals champion policies that secure environmental justice. Beauty product use is an understudied source of environmental chemical exposures. Beauty products can include reproductive and developmental toxicants such as phthalates and heavy metals; however, disclosure requirements are limited and inconsistent...

BACKGROUND: Increased stiffness of large arteries is an important determinant of cardiovascular disease risk. Higher values of arterial stiffness measured by carotid-femoral pulse wave velocity (cf-PWV) have been measured in adult African-Americans compared with whites. Studies assessing ethnic differences in cf-PWV among children and adolescents are scarce. This study sought to evaluate the association between ethnicity and cf-PWV in Brazilian children and adolescents. METHODS: Seven hundred and seventy-one children and adolescents (211 blacks and 560 nonblacks, 11...

BACKGROUND: Tobacco smoke contains known hormonally active chemicals and reproductive toxicants. Several studies have examined prenatal maternal smoking and offspring age at menarche, but few examined earlier pubertal markers, nor accounted for exposure during childhood. Our objective was to examine pre- and postnatal smoke exposure in relation to timing of early pubertal events. METHODS: An ethnically diverse cohort of 1239 girls was enrolled at age 6-8 years old for a longitudinal study of puberty at three US sites...

BACKGROUND: Elevated prolactin levels (hyperprolactinemia) are a frequent adverse effect of antipsychotic medications, especially in young populations. Prolonged hyperprolactinemia may affect sexual functioning and the onset and progression of puberty. OBJECTIVE: This study assessed potentially prolactin-related treatment-emergent adverse events (PPRL-TEAEs) and sexual maturation during long-term treatment of adolescents with paliperidone extended-release (ER). METHODS: This post hoc analysis of a 2-year open-label multicenter study (NCT00488319) included patients of either sex aged 12-17 years at study enrollment, diagnosed with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, 4th edition [DSM-IV]) for ≥1 year, who had received one or more adequate antipsychotic treatment prior to enrollment but had not responded sufficiently...

BACKGROUND Alopecia areata is an immune mediated inflammatory hair loss, which occurs in all ethnic and age groups, and both sexes. However no significant etiology has been known for this disease. Helicobacter pylori (H. pylori) , is an organism colonized in gastric mucosa. This bacterium has been associated with certain extra-digestive dermatological conditions. The causal relationship between alopecia areata and H. pylori infection has been discussed in literature. Therefore, we conducted this study to evaluate the prevalence of H...

BACKGROUND: Pubertal milestones, such as onset of breast development and menstruation, play an important role in breast cancer etiology. It is unclear if these milestones are different in girls with a first- or second-degree breast cancer family history (BCFH). METHODS: In the LEGACY Girls Study (n = 1040), we examined whether three mother/guardian-reported pubertal milestones (having reached Tanner Stage 2 or higher (T2+) for breast and pubic hair development, and having started menstruation) differed by BCFH...
