Several ethnic minority groups experience elevated rates of first-episode psychosis (FEP), but most studies have been conducted in urban settings. We investigated whether incidence varied by ...ethnicity, generation status, and age-at-immigration in a diverse, mixed rural, and urban setting.
We identified 687 people, 16-35 years, with an ICD-10 diagnosis of FEP, presenting to Early Intervention Psychosis services in the East of England over 2 million person-years. We used multilevel Poisson regression to examine incidence variation by ethnicity, rural-urban setting, generation status, and age-at-immigration, adjusting for several confounders including age, sex, socioeconomic status, population density, and deprivation.
People of black African (incidence rate ratio: 4.06; 95% confidence interval CI: 2.63-6.25), black Caribbean (4.63; 95% CI: 2.38-8.98) and Pakistani (2.31; 95% CI: 1.35-3.94) origins were at greatest FEP risk relative to the white British population, after multivariable adjustment. Non-British white migrants were not at increased FEP risk (1.00; 95% CI: 0.77-1.32). These patterns were independently present in rural and urban settings. For first-generation migrants, migration during childhood conferred greatest risk of psychotic disorders (2.20; 95% CI: 1.33-3.62).
Elevated psychosis risk in several visible minority groups could not be explained by differences in postmigratory socioeconomic disadvantage. These patterns were observed across rural and urban areas of our catchment, suggesting that elevated psychosis risk for some ethnic minority groups is not a result of selection processes influencing rural-urban living. Timing of exposure to migration during childhood, an important social and neurodevelopmental window, may also elevate risk.
Approximately 1 in 5 adults in the US had a sexually transmitted infection (STI) in 2018. This review provides an update on the epidemiology, diagnosis, and treatment of gonorrhea, chlamydia, ...syphilis, Mycoplasma genitalium, trichomoniasis, and genital herpes.
From 2015 to 2019, the rates of gonorrhea, chlamydia, and syphilis increased in the US; from 1999 to 2016, while the rates of herpes simplex virus type 1 (HSV-1) and HSV-2 declined. Populations with higher rates of STIs include people younger than 25 years, sexual and gender minorities such as men and transgender women who have sex with men, and racial and ethnic minorities such as Black and Latinx people. Approximately 70% of infections with HSV and trichomoniasis and 53% to 100% of extragenital gonorrhea and chlamydia infections are asymptomatic or associated with few symptoms. STIs are associated with HIV acquisition and transmission and are the leading cause of tubal factor infertility in women. Nucleic acid amplification tests have high sensitivities (86.1%-100%) and specificities (97.1%-100%) for the diagnosis of gonorrhea, chlamydia, M genitalium, trichomoniasis, and symptomatic HSV-1 and HSV-2. Serology remains the recommended method to diagnose syphilis, typically using sequential testing to detect treponemal and nontreponemal (antiphospholipid) antibodies. Ceftriaxone, doxycycline, penicillin, moxifloxacin, and the nitroimidazoles, such as metronidazole, are effective treatments for gonorrhea, chlamydia, syphilis, M genitalium, and trichomoniasis, respectively, but antimicrobial resistance limits oral treatment options for gonorrhea and M genitalium. No cure is available for genital herpes. Effective STI prevention interventions include screening, contact tracing of sexual partners, and promoting effective barrier contraception.

HPV16 is a common sexually transmitted infection although few infections lead to cervical precancer/cancer; we cannot distinguish nor mechanistically explain why only certain infections progress. ...HPV16 can be classified into four main evolutionary-derived variant lineages (A, B, C, D) that have been previously suggested to have varying disease risks.
We used a high-throughput HPV16 whole-genome sequencing assay to investigate variant lineage risk among 3215 HPV16-infected women. Using sublineages A1/A2 as the reference, we assessed all variant lineage associations with infection outcome over three or more years of follow-up: 1107 control subjects (<CIN2), 906 CIN2, 1008 CIN3, 69 squamous cell carcinomas (SCC), 85 adenocarcinomas in situ (AIS), and 40 adenocarcinomas. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). All statistical tests were two-sided.
A4 sublineage was associated with an increased risk of cancer, specifically adenocarcinoma (OR = 9.81, 95% CI = 2.02 to 47.69, P = 4.7x10(-03)). Lineage B had a lower risk of CIN3 (OR = 0.51, 95% CI = 0. 28 to 0.91, P = 02) while lineage C showed increased risk (OR = 2.06, 95% CI = 1.09 to 3.89, P = 03). D2/D3 sublineages were strongly associated with an increased risk of CIN3 and cancer, particularly D2 (OR for cancer = 28.48, 95% CI = 9.27 to 87.55, P = 5.0x10(-09)). D2 had the strongest increased risk of glandular lesions, AIS (OR = 29.22, 95% CI = 8.94 to 95.51, P = 2.3x10(-08)), and adenocarcinomas (OR = 137.34, 95% CI = 37.21 to 506.88, P = 1.5x10(-13)). Moreover, the risk of precancer and cancer for specific variant lineages varied by a women's race/ethnicity; those women whose race/ethnicity matched that of the infecting HPV16 variant had an increased risk of CIN3 + (P < 001).
Specific HPV16 variant sublineages strongly influence risk of histologic types of precancer and cancer, and viral genetic variation may help explain its unique carcinogenic properties.
Every woman experiences the menopause transition period in a very individual way. Menopause symptoms and management are greatly influenced by socioeconomic status in addition to genetic background ...and medical history. Because of their very unique cultural heritage and often holistic view of health and well-being, menopause symptoms and management might differ greatly in aboriginals compared to non-aboriginals. Our aim was to investigate the extent and scope of the current literature in describing the menopause experience of aboriginal women.
Our systematic literature review included nine health-related databases using the keywords 'menopause' and 'climacteric symptoms' in combination with various keywords describing aboriginal populations. Data were collected from selected articles and descriptive analysis was applied.
Twenty-eight relevant articles were included in our analysis. These articles represent data from 12 countries and aboriginal groups from at least eight distinctive geographical regions. Knowledge of menopause and symptom experience vary greatly among study groups. The average age of menopause onset appears earlier in most aboriginal groups, often attributed to malnutrition and a harsher lifestyle.
This literature review highlights a need for further research of the menopause transition period among aboriginal women to fully explore understanding and treatment of menopause symptoms and ultimately advance an important dialogue about women's health care.
Racial differences in susceptibility and progression of pancreatitis have been reported in epidemiologic studies using administrative or retrospective data. There has been little study, however, on ...the clinical profile, causes, and outcome of chronic pancreatitis (CP) in black patients.
We analyzed data on black patients with CP prospectively enrolled in the multicenter North American Pancreatitis Studies from 26 US centers during the years 2000-2014. CP was defined by definitive evidence on imaging studies or histology. Information on demographics, etiology, risk factors, disease phenotype, treatment, and perceived effectiveness was obtained from responses to detailed questionnaires completed by both patients and physicians.
Of the 1,159 patients enrolled, 248 (21%) were black. When compared with whites, blacks were significantly more likely to be male (60.9 vs. 53%), ever (88.2 vs. 71.8%), or current smokers (64.2 vs. 45.9%), or have a physician-defined alcohol etiology (77 vs. 41.9%). There was no overall difference in the duration of CP although for alcoholic CP, blacks had a longer duration of disease (8.6 vs. 6.97 years; P=0.02). Blacks were also significantly more likely to have advanced changes on pancreatic morphology (calcifications (63.3 vs. 55.2%), atrophy (43.2 vs. 34.6%), pancreatic ductal stricture or dilatation (72.6 vs. 65.5%) or common bile duct stricture (18.6 vs. 8.2%)) and function (endocrine insufficiency 39.9 vs. 30.2%). Moreover, the prevalence of any (94.7 vs. 83%), constant (62.6 vs. 51%), and severe (78.4 vs. 65.8%) pain and disability (35.1 vs. 21.4%) were significantly higher in blacks. Observed differences were in part related to variances in etiology and duration of disease. No differences in medical or endoscopic treatments were seen between races although prior cholecystectomy (31.1 vs. 19%) was more common in white patients.
Differences were observed between blacks and whites in the underlying cause, morphologic expression, and pain characteristics of CP, which in part are explained by the underlying risk factor(s) with alcohol and tobacco being much more frequent in black patients as well as disease duration.
Estimates of the prevalence of chronic hepatitis B (CHB) in the United States differ significantly, and the contribution of foreign‐born (FB) persons has not been adequately described. The aim of ...this study was to estimate the number of FB persons in the United States living with CHB by their country of origin. We performed a systematic review for reports of HBsAg seroprevalence rates in 102 countries (covering PubMed from 1980 to July 2010). Data from 1,373 articles meeting inclusion criteria were extracted into country‐specific databases. We identified 256 seroprevalence surveys in emigrants from 52 countries (including 689,078 persons) and 1,797 surveys in the general populations of 98 countries (including 17,861,035 persons). Surveys including individuals with lower or higher risk of CHB than the general population were excluded. Data were combined using meta‐analytic methods to determine country‐specific pooled CHB prevalence rates. Rates were multiplied by the number of FB living in the United States in 2009 by country of birth from the U.S. Census Bureau to yield the number of FB with CHB from each country. We estimate a total of 1.32 million (95% confidence interval: 1.04‐1.61) FB in the United States living with CHB in 2009; 58% migrated from Asia and 11% migrated from Africa, where hepatitis B is highly endemic. Approximately 7% migrated from Central America, a region with lower CHB rates, but many more emigrants to the United States. This analysis suggests that the number of FB persons living with CHB in the United States may be significantly greater than previously reported. Assuming 300,000‐600,000 U.S.‐born persons with CHB, the total prevalence of CHB in the United States may be as high as 2.2 million. (Hepatology 2012)
In Australia and Canada, the sexual health needs of migrant and refugee women have been of increasing concern, because of their underutilization of sexual health services and higher rate of sexual ...health problems. Previous research on migrant women’s sexual health has focused on their higher risk of difficulties, or barriers to service use, rather than their construction or understanding of sexuality and sexual health, which may influence service use and outcomes. Further, few studies of migrant and refugee women pay attention to the overlapping role of culture, gender, class, and ethnicity in women’s understanding of sexual health. This qualitative study used an intersectional framework to explore experiences and constructions of sexual embodiment among 169 migrant and refugee women recently resettled in Sydney, Australia and Vancouver, Canada, from Afghanistan, Iraq, Somalia, South Sudan, Sudan, Sri Lanka, India, and South America, utilizing a combination of individual interviews and focus groups. Across all of the cultural groups, participants described a discourse of shame, associated with silence and secrecy, as the dominant cultural and religious construction of women’s sexual embodiment. This was evident in constructions of menarche and menstruation, the embodied experience that signifies the transformation of a girl into a sexual woman; constructions of sexuality, including sexual knowledge and communication, premarital virginity, sexual pain, desire, and consent; and absence of agency in fertility control and sexual health. Women were not passive in relation to a discourse of sexual shame; a number demonstrated active resistance and negotiation in order to achieve a degree of sexual agency, yet also maintain cultural and religious identity. Identifying migrant and refugee women’s experiences and constructions of sexual embodiment are essential for understanding sexual subjectivity, and provision of culturally safe sexual health information in order to improve well-being and facilitate sexual agency.
To investigate the association between eating behaviours (eating speed and energy intake of main meals) and overweight in pre-school children.
Cross-sectional study. Data consisted of measurements ...(height and weight), questionnaire information (eating behaviours of eating speed and overeating) and on-site observation data (meal duration and energy intake of main meals).
Seven kindergartens in Beijing, China.
Pre-school children (n 1138; age range 3·1-6·7 years old) from seven kindergartens participated in the study.
The multivariate-adjusted odds ratio of overweight in participants with parent-reported 'more than needed food intake' was 3·02 (95 % CI 2·06, 4·44) compared with the 'medium food intake' participants, and higher eating speed was associated with childhood overweight. For the two observed eating behaviours, each 418·7 kJ (100 kcal) increase of lunch energy intake significantly increased the likelihood for overweight by a factor of 1·445, and each 5-min increase in meal duration significantly decreased the likelihood for overweight by a factor of 0·861. Increased portions of rice and cooked dishes were significantly associated with overweight status (OR = 2·274; 95 % CI 1·360, 3·804 and OR = 1·378; 95 % CI 1·010, 1·881, respectively).
Eating speed and excess energy intake of main meals are associated with overweight in pre-school children.
