Background
Because of time and cost constraints, objective classification of atopic and nonatopic asthma has been limited in large epidemiologic studies. However, as we try to better understand exposure-outcome associations and ensure appropriate treatment of asthma, it is important to focus on phenotype-defined asthma classification.Objective
To compare atopic and nonatopic asthma in rural children with regard to risk factors and clinical outcomes.Methods
We conducted a cross-sectional study in rural Saskatchewan, Canada, in 2011. Parents of 6- to 14-year-old children completed a health and exposure survey. Skin prick tests were completed in a subsample of 529 children. Asthma was based physician diagnosis. Asthma status was defined as no asthma, nonatopic asthma, and atopic asthma.Results
Asthma prevalence was 14.7% of which 32.1% of cases were atopic. After adjustment, early respiratory illness and a family history of asthma were predictors of childhood asthma, regardless of atopic status (P < .05). Being overweight and having a dog in the home were associated with an increased risk of nonatopic asthma (P < .05). A mother with a history of smoking increased the risk of atopic asthma (P = .01). Compared with those with nonatopic asthma, in the past 12 months, children with atopic asthma were more likely to report a sneezy, runny, or blocked nose or have shortness of breath (odds ratio >2), whereas those with nonatopic asthma were more likely to have parents who missed work (odd ratio >3). Those with nonatopic asthma had significantly lower forced expiratory volume in 1 second compared w2ith those with atopic asthma.Conclusion
Exposures may contribute differentially to atopic and nonatopic asthma and result in differential clinical presentation or burden. The study of these characteristics is important for etiologic understanding and management decisions. 相似文献2.

Objective
To describe the perspectives and experiences of athletic trainers, coaches, and student-athletes approximately three years post-implementation of the NCAA sickle cell trait (SCT) screening policy.Participants
Two-hundred and eight student-athletes, 32 athletic trainers, and 43 coaches from 10 NCAA Division I (DI) institutions in North Carolina from January to June 2014.Methods
Two online surveys were used to assess knowledge, perspectives, and experiences.Results
Athletic staff were more supportive than student-athletes of the need for the policy. Noted challenges included variation in implementation and follow-up for SCT-positive athletes, financial costs to institutions and athletes, and timing of the screening.Conclusions
More education about SCT is needed for student-athletes and athletic staff in order to help make the implementation more successful. All parties need to be in agreement regarding the importance of knowing which student-athletes have SCT and how that information will be utilized. 相似文献3.

Background
Atopic diseases have increased since the second half of the previous century. Atopic workers are at higher risk to be sensitized to latex, and the first years of exposure are supposed to be especially risky.Objective
To assess atopic status and rate of latex sensitization in health care students starting their exposure to latex gloves.Methods
We analyzed medical surveillance data from 1,628 health care students from 2010 to 2016. Students completed a questionnaire focused on their previous and current latex exposure and personal and family histories of allergic diseases; underwent skin prick testing with common allergens and latex extract (and/or total and latex-specific immunoglobulin E in serum); and underwent a medical examination.Results
Skin prick test results for common inhalant allergens showed that 807 of 1,628 students (49.6%) had atopy. Atopy by skin prick testing was associated with male sex (odds ratio 1.49, 95% confidence interval 1.18–1.86), a personal history of oculorhinitis or asthma (odds ratio 10.22, 95% confidence interval 7.4–14.13), and atopic eczema (odds ratio 1.87, 95% confidence interval 1.05–3.36) at multivariate regression analysis. Eleven students (0.7% of total population) were found to be sensitized to latex and all had atopy.Conclusion
Despite the high prevalence of atopy in health care students of Trieste, the latex sensitization rate is very low and comparable to general population. This is reasonably due to the low exposure to latex gloves at the time of the evaluation and to low latex release from the gloves currently used in our hospital. 相似文献4.

Background
There is a trend toward an increased worldwide prevalence of allergic diseases. It is speculated that industrialization with resultant air pollution plays a role. However, there are sparse epidemiologic data on the relation between air pollution and atopic dermatitis (AD) in adults.Objective
To investigate the relation between exposure to air pollutants and adult AD in a cross-sectional study based on data from the National Health Insurance Research Database in Taiwan.Methods
We identified 1,023 adult patients with AD and 4,092 age- and sex-matched controls without allergic diseases in 2011. Using data from 71 Environmental Protection Agency monitoring stations across Taiwan, levels of exposure to air pollutants were determined by the location of a subject's place of residence. Multivariate logistic regression analysis, adjusted for age, sex, levels of urbanization, and family income, was performed.Results
We found an association between particulate matter <2.5 μm in diameter or the Pollutant Standards Index (the highest sub-index of the concentrations of 5 main air pollutants after transformation) and the development of adult AD. The adjusted odds ratios were 1.05 (95% confidence interval 1.02–1.08) and 1.02 (95% confidence interval 1.01–1.03), respectively.Conclusion
These results demonstrated that air pollution, represented by particulate matter <2.5 μm in diameter or the Pollutant Standards Index, was modestly associated with the development of AD in adults. 相似文献5.
Objective
This article reviews the latest science and epidemiologic studies related to drug allergy in children and adults to explore possible mechanisms related to female propensity for drug allergy.Data Sources
PubMed literature review, focusing primarily on the last 5 years.Study Selections
Articles reviewing the science behind female predisposition to atopic and asthmatic conditions and epidemiologic studies reviewing drug allergy and drug-induced anaphylaxis.Results
Despite adult female predilection for atopic conditions, few laboratory studies explore sex-specific mechanisms in atopic/allergic diseases, and most are focused on autoimmunity and asthma. Drug allergy is more frequently reported in adult females compared with adult males. Adult females are also more likely to have drug-induced anaphylaxis (DIA), although no clear sex predominance has been reported in fatal or severe DIA. Studies in children suggest the reverse picture, with prepubertal males more likely to have drug allergy and DIA than prepubertal girls.Conclusion
Possible explanations for female predisposition for drug allergy are multifactorial and include disproportionate utilization of health care with more exposure to antibiotics or medications, genetic factors related to the X chromosome, epigenetic changes, and discrepant hormonal interactions with immune cells. 相似文献6.

Objectives
This study aims to explore the spatial characteristics of the alpha-fetoprotein (AFP) reference value in healthy Chinese adults, and its relationship to geographical location.Methods
A total of 9396 AFP reference values were collected from patients in 96 administrative units. A correlation analysis and support vector machine (SVM) were employed to extract dependent geographical factors and predict the reference values in the entire country, respectively. A geostatistics analysis was developed to reveal the spatial characteristics of the value.Results
Under the long-term influence of geographical environment, AFP reference values show spatial autocorrelation and regional variation. The values are higher in western and northern areas than in eastern and southern areas of China.Conclusions
The AFP reference values show regional differences, and this difference should be considered in clinical practice. 相似文献7.
Objective
To review the current state of the literature regarding the socioeconomics of atopic dermatitis (AD)—more specifically how socioeconomic status (SES) affects AD risk and how the presence of AD may affect one’s SES—as well as discuss the cost of the disease to society.Data Sources
A PubMed search was performed to include English-language articles with the keywords atopic dermatitis, cost, finances, economic, income, career, socioeconomic, with preference to those written in the last 5 years.Study Selections
Studies were included if they provided information pertaining to socioeconomics in relation to disease severity, disease incidence, direct costs, indirect costs, and effects on work, education, and career choice.Results
Many studies have reported that higher SES is associated with increased AD prevalence, whereas lower SES is associated with increased AD severity. Regardless of patient SES, AD creates substantial direct costs that affect the patient, patient’s family, and the payer. Additionally, the effects of the disease create indirect costs from absenteeism and presenteeism, as well as opportunity costs from hinderances in learning, affecting patient SES and the economy.Conclusion
Given the substantial and growing burden on the patient and the economy when access to appropriate treatment is limited, the socioeconomic burden of AD represents a tangible public health concern that must be addressed. 相似文献8.

Background
Increased photoprotection by natural melanin allows for African-Americans to be less impacted by photoaging than Caucasians. However, less is known about chronological aging in this population.Objective
To create a photonumeric scale for African-Americans to evaluate chronological skin aging and to explore contributing elements to intrinsic aging.Methods
Standardized photographs of the upper inner arm were taken from 75 African-American participants. Five participants were chosen as standards to create a 9-point photonumeric scale (0 = none, 8 = most severe). The scale was utilized by three blinded dermatologists to independently rate participants' photographs.Results
The interrater agreements were 0.768 (95% CI: 0.671–0.834) for trial 1 and 0.725 (0.608–0.794) for trial 2. The intrarater agreements were 0.757 (0.596–0.875), 0.850 (0.771–0.903), and 0.790 (0.686–0.855) for the three raters. Averaged chronological aging scores were correlated with participants' survey responses, which revealed age as a significant predictor (r = 0.72, p < 0.001).Limitation
Our study was limited by the sample size, although the number of study participants was similar on a investigation in Caucasians.Conclusion
This study created the first reliable photonumeric scale for chronologic skin aging in African-Americans and found increased age and greater BMI as contributors to intrinsic skin aging phenotype in this population. 相似文献9.

Background
Prostate cancer affects black men disproportionately. Black men have an increased incidence of prostate cancer diagnoses at earlier ages and higher grade as indicated by Gleason score, compared to other races. This study investigates the impact of socioeconomic status (SES) on prostate cancer tumor grade among black men.Methods
Black men with a prostate cancer diagnosis during 1973–2011 were examined using individual-level data from the SEER NLMS database. Logistic regression model estimated the likelihood of receiving a diagnosis of high versus low grade prostate cancer based on self-reported SES status at the time of diagnosis.Results
Men who completed high school only were statistically significantly more likely to have a higher prostate cancer grade than those with a bachelor's degree or higher. However, there was no dose-response effect across educational strata. Retirees were 30% less likely to have higher grade tumors compared to those who were employed.Conclusions
SES differences among black men did not fully explain the high grade of prostate cancer. Further research is needed on the biology of the disease and to assess access to medical care and prostate health education, discrimination, stress exposures, and social norms that might contribute to the aggressiveness of prostate cancer among black men. 相似文献10.

Background
African American adults achieve smaller amounts of weight loss than their white counterparts when exposed to the same intervention and are more likely to regain weight during long-term follow-up.Objective
To identify perceived motivators, barriers, and facilitators to weight loss and behavior change among African American adults.Methods
Two focus groups were conducted between April and May 2015 at an urban community health center in Baltimore City, Maryland. A total of 13 participants took part in the discussions. Eligible participants were obese (BMI 30+) African American adults aged 21–70 who had at least one obesity-related comorbidity. Discussion questions were designed to identify the personal, social, and environmental factors that influence weight loss and behavior change among urban minority populations.Results
Statements were first classified as a motivator, barrier, or facilitator, then divided further as a personal, social, or environmental factor influencing weight loss and behavior change. Among the findings, several novel motivators (reducing or eliminating medication, improving physical intimacy) and barriers (personal transportation, lack of access to scales) emerged that were not previously characterized in the existing literature.Conclusions
This study was intended to provide preliminary evidence that may be used to guide the development of innovative and culturally relevant weight-loss interventions in the future. Results are applicable to similar urban minority populations. 相似文献11.

Background
As with many other populations, abuse of older adults is a growing problem across the Africa Diaspora. Modernization and urbanization are eroding the traditional values of respect for older adults. Also, older adults living in environments with limited social and economic resources, and having no means of economic support create a recipe for elder abuse and neglect.Methods
This article reviews the current literature on the epidemiology, risk factors, and interventions used for elder abuse across the African Diaspora.Results
Reports of elder abuse range from 24.9% to 81.1% across the Diaspora. Risk factors include cognitive and physical impairment, social isolation, lack of resources and widowhood.Conclusion
Community-based programs using the unique social networks of older populations of African descent can provide a venue to improve caregiver training and support, reinforce traditional filial and informal caregiving practices, increase the utilization of available governmental and institutional. 相似文献12.
Background
Atopic disorders have been reported in CHARGE syndrome, but the prevalence and underlying mechanisms are not known.Methods
We performed a retrospective study of atopic disorders in 23 individuals with CHARGE syndrome, and reviewed other published reports of atopic disorders in CHARGE syndrome. We assayed for enrichment of atopic disorders in CHARGE syndrome based on gender and presence of a CHD7 pathogenic variant.Results
In our cohort, 65% (15/23) of individuals with CHARGE syndrome were found to have a pathogenic CHD7 variant. Overall, 65% (15/23) of individuals with CHARGE had atopic disorders. Among the 23 individuals with CHARGE, 22% (5/23) had food allergy, 26% (6/23) exhibited drug allergy, 22% (5/23) had contact allergy, 9% (2/23) had allergic rhinitis, and 22% (5/23) had asthma. In our cohort, the proportion of males to females with CHARGE and atopic disorders was 11:4 (P < 0.01), and there was no significant difference between atopic disorders in individuals with CHD7 pathogenic variants and those without CHD7 pathogenic variants (P > 0.05).Conclusion
In our cohort of 23 individuals with CHARGE syndrome, 15 (65%) exhibited atopic disorders, with a slight male predominance. 相似文献13.

Background
Few studies have examined health behavior interventions for African American women who are uterine cancer survivors. Black-white differences in uterine cancer survival suggest that there are unmet needs among these survivors.Methods
This article identifies opportunities to address disparities in uterine corpus cancer survival and quality of life, and thereby to increase uterine cancer survivorship among African American women.Results
For cancer survivors, common side effects, lasting for long periods after cancer treatment, include fatigue, loss of strength, lymphedema, and difficulty sleeping. A variety of interventions have been evaluated to address physical and mental health concerns, including exercise and dietary interventions. Considerable information exists about the effectiveness of such interventions for alleviating distress and improving quality of life among cancer survivors, but few studies have focused specifically on African American women with a uterine corpus cancer diagnosis. Research-tested culturally tailored lifestyle interventions are lacking.Conclusions
There is a need for a better understanding of uterine cancer survivorship among African American women. Additional evaluations of interventions for improving the quality of life and survival of African American uterine cancer survivors are needed. 相似文献15.

Background
Social and cultural outcomes are critically important in medical education. A large medical school located in the United States implemented a learning community model intended to promote social and cultural growth among its medical students. The purpose of this study was to evaluate the degree to which medical students from the same peer cohort were socially connected across racial and sex groups.Methods
Because most assessments involving social and cultural outcomes involve self-reported data of a personal nature, the possibility of social desirability bias is increased. To mitigate this threat, this study utilized a novel method for measuring medical students social connectedness by having peers in one's advisory college provide social connectedness ratings about one another.Results
While surface level results did not reveal any significant differences, a closer inspection of data revealed Black females were less socially connected with medical student peers from their cohort than other peer groups.Discussion
Possible explanations for this are discussed. Future research should continue to investigate the experiences of Black females in medical schools so as to better understand the needs of this important and valuable subpopulation of students. 相似文献16.

Background
Construction of appropriate test items is a challenge in preparing quality multiple choice questions. Item analysis provides valuable feedback data on validity of multiple choice questions. The present study was conducted to evaluate the difficulty index, discrimination index and distracter efficiency of the items present in the multiple choice questions of post graduate dental entrance examinations.Methods
A list consisting of 20 MCQs was taken from the entrance exam books of MCQs on an introductory topic and administered to 104 undergraduate students.Results
In the present study 15% of the MCQs related to impression making procedure were difficult with difficulty index (p) less than 30%, 15% were poor discriminators and 55% had at least one non-functional distracter.Conclusion
Item analysis of MCQs in post graduate entrance examinations demonstrated low difficulty index, discrimination index and distracter efficiency. Hence, we propose a strong need for faculty training in test constructors and their post validation. 相似文献17.

Introduction
The purpose of this study was to evaluate the two-body wear resistances of natural enamel and four dental materials in vitro.Methods
The testing machine was modified to form a type of pin-on-disk wear test apparatus. Four dental material specimens (Au-Pd alloy, Ag-Pd alloy, FiltekTMP60 and FiltekTMZ350 composite resins) and enamel were used as the pins, and a steatite ceramic grinding wheel was used as the abrasive counter face. The wear volume loss and the rigidity value was measured. The worn surface and the element analysis of the debris were analyzed.Result
The wear volume loss of Au-Pd alloy and its steatite antagonists were the nearest to those of the dental enamel. SEM microphotographs showed that, the main wear mechanism of the dental materials was abrasive and adhesive wear.Conclusions
Au-Pd alloy had good wear resistance and was more suitable for dental applications than other three dental materials. 相似文献18.

Background
Fanconi Anemia (FA) is a rare and heterogeneous genetic syndrome. It is associated with short stature, bone marrow failure, high predisposition to cancer, microcephaly and congenital malformation. Many genes have been associated with FA. Previously, two adult patients with biallelic pathogenic variant in Breast Cancer 1 gene (BRCA1) had been identified in Fanconi Anemia-like condition.Clinical report
The proband was a 2.5 year-old girl with severe short stature, microcephaly, neurodevelopmental delay, congenital heart disease and dysmorphic features. Her parents were third degree cousins. Routine screening tests for short stature was normal.Methods
We conducted whole exome sequencing (WES) of the proband and used an analysis pipeline to identify rare nonsynonymous genetic variants that cause short stature.Results
We identified a homozygous loss-of-function BRCA1 mutation (c.2709T > A; p. Cys903*), which promotes the loss of critical domains of the protein. Cytogenetic study with DEB showed an increased chromosomal breakage. We screened heterozygous parents of the index case for cancer and we detected, in her mother, a metastatic adenocarcinoma in an axillar lymph node with probable primary site in the breast.Conclusion
It is possible to consolidate the FA-like phenotype associated with biallelic loss-of-function BRCA1, characterized by microcephaly, short stature, developmental delay, dysmorphic face features and cancer predisposition. In our case, the WES allowed to establish the genetic cause of short stature in the context of a chromosome instability syndrome. An identification of BRCA1 mutations in our patient allowed precise genetic counseling and also triggered cancer screening for the patient and her family members. 相似文献19.

Background
Food allergies are increasingly prevalent in the pediatric population. Balancing allergen avoidance with the promotion of healthy eating behaviors can be challenging for families.Objective
To characterize mealtime behaviors among parents of young children with food allergy.Methods
Seventy-four parents of young children with food allergies (≤7 years of age) completed measures of mealtime behavior, perceptions of food allergy risk and severity, pediatric parenting stress, and food allergy–related quality of life. Mealtime behavior reports were compared with published data regarding typically developing children, young children with type 1 diabetes, and children with diagnosed feeding disorders (with or without related medical factors).Results
Parents of young children with food allergies reported frequent mealtime concerns. Specifically, they reported significantly more mealtime behavioral concerns than typically developing peers, comparable mealtime behavioral concerns to young children with type 1 diabetes, and significantly fewer mealtime behavioral concerns than children with diagnosed feeding disorders. Parental mealtime concerns were positively correlated with other parent perceptions of food allergy, such as risk of allergen exposure, illness-related parenting stress, and food allergy–related quality of life.Conclusion
Young children with food allergy and their parents are more likely to exhibit mealtime behavioral concerns than typically developing peers and their parents. Future research should investigate the effect of food allergies and maladaptive mealtime behaviors on children's nutrition to provide clinical guidelines for parents who may benefit from psychosocial and/or nutritional support. 相似文献20.
