Human papillomavirus (HPV) is the most common sexually transmitted infection in the US. HPV vaccine is a viable source of prevention against high-risk strains that are likely to cause cancer. However, particularly among racial and ethnic minorities such as Chinese Americans, HPV vaccination rates are suboptimal. The goal of this study was to evaluate the effect of a culturally tailored intervention on HPV vaccine uptake in Chinese Americans. We designed and implemented a multilevel longitudinal pilot study to examine the efficacy of the HPV intervention among Chinese American parents/guardians. We recruited 180 participants from federally qualified health center and community-based clinics that serve predominantly low-income Chinese Americans in Philadelphia. Participants were randomized into an intervention group (n?=?110) or a control group (n?=?70). The intervention group received an HPV specific intervention, while the control group received a general health intervention. The primary outcome was medical record-confirmed receipt of first shot and completion of HPV vaccine within six months of receiving the interventions. Repeated measure ANOVA was utilized to examine the intervention effect on knowledge between intervention and control groups. Knowledge differed significantly, with participants in the intervention group demonstrating the greatest improvement following the intervention. A multivariable logistic regression was used to examine the association between HPV vaccine initiation and study group assignment. There was a significant effect of provider recommendation, parent’s gender, and health insurance status on HPV vaccine uptake. This study demonstrated positive impact of a culturally tailored intervention on HPV vaccination uptake among Chinese Americans.
We describe a case of granulomatosis with polyangiitis (GPA; formerly named Wegener granulomatosis) that presented initially as florid areas of gingival swelling. The patient also had upper respiratory symptoms that included sinus congestion and cough of recent onset. Clinical-pathologic correlation aided the interpretation of non-specific biopsy findings and immediate referral to an appropriate medical specialist. Treatment was rendered at an early stage of disease with a good response to date. Review of the literature indicates that gingival swelling, often with the characteristic appearance of “strawberry gingivitis” may represent the initial sign of disease in 2% of patients with GPA. Biopsy of gingival lesions often shows a non-specific histologic appearance that should be interpreted in the context of the clinical appearance and pertinent medical history. The clinical investigations that lead to definitive diagnosis and treatment are presented to facilitate the management of this uncommon but potentially fatal condition. 相似文献
ObjectivesThe objective of this study was to assess the performance of models of primary healthcare (PHC) delivered in First Nation and adjacent communities in Manitoba, using hospitalization rates for ambulatory care sensitive conditions (ACSC) as the primary outcome.MethodsWe used generalized estimating equation logistic regression on administrative claims data for 63 First Nations communities from Manitoba (1986–2016) comprising 140,111 people, housed at the Manitoba Centre for Health Policy. We controlled for age, sex, and socio-economic status to describe the relationship between hospitalization rates for ACSC and models of PHC in First Nation communities.ResultsHospitalization rates for acute, chronic, vaccine-preventable, and mental health-related ACSCs have decreased over time in First Nation communities, yet remain significantly higher in First Nations and remote non-First Nations communities as compared with other Manitobans. When comparing different models of care, hospitalization rates were historically higher in communities served by health centres/offices, whether or not supplemented by itinerant medical services. These rates have significantly declined over the past two decades.ConclusionLocal access to a broader complement of PHC services is associated with lower rates of avoidable hospitalization in First Nation communities. The lack of these services in many First Nation communities demonstrates the failure of the current Canadian healthcare system to meet the need of First Nation peoples. Improving access to PHC in all 63 First Nation communities can be expected to result in a reduction in ACSC hospitalization rates and reduce healthcare cost. 相似文献
ObjectivesThe last Canadian biobehavioural surveillance study of HIV and other sexually transmitted and blood-borne infections (STBBI) among gay, bisexual and other men who have sex with men (GBM) was conducted in 2010. We designed a study to measure STBBI prevalence among GBM in metropolitan Montreal, Toronto and Vancouver and to document related preventive and risk behaviours.MethodsThe Engage Cohort Study used respondent-driven sampling (RDS) to recruit GBM who reported sex with another man in the past 6 months. At baseline, we examined recruitment characteristics of the samples, and the RDS-II-adjusted distributions of socio-demographics, laboratory-confirmed HIV and other STBBI prevalence, and related behaviours, with a focus on univariate differences among cities.ResultsA total of 2449 GBM were recruited from February 2017 to August 2019. HIV prevalence was lower in Montreal (14.2%) than in Toronto (22.2%) or Vancouver (20.4%). History of syphilis infection was similar across cities (14–16%). Vancouver had more HIV-negative/unknown participants who reported never being HIV tested (18.6%) than Toronto (12.9%) or Montreal (11.5%). Both Montreal (74.9%) and Vancouver (78.8%) had higher proportions of men who tested for another STBBI in the past 6 months than Toronto (67.4%). Vancouver had a higher proportion of men who used pre-exposure prophylaxis (PrEP) in the past 6 months (18.9%) than Toronto (11.1%) or Montreal (9.6%).ConclusionThe three largest cities of Canada differed in HIV prevalence, STBBI testing and PrEP use among GBM. Our findings also suggest the need for scale-up of both PrEP and STI testing among GBM in Canada. 相似文献
ObjectiveTo systematically review the literature on the mental health of adolescents associated with sexual and reproductive outcomes, and compare the mental health outcomes with that of other age groups.MethodsWe searched seven databases for relevant peer-reviewed articles published between 1 January 2010 and 25 April 2019. Our inclusion criteria required that the study included age-disaggregated data on adolescents, and focused and assessed mental health outcomes associated with pregnancy or sexually transmitted infections. We extracted data on the specific health event, the mental health outcome and the method of measuring this, and comparisons with other age groups.FindingsAfter initially screening 10 818 articles by title and abstract, we included 96 articles in our review. We observed that a wide-ranging prevalence of mental ill-health has been reported for adolescents. However, most studies of mental health during pregnancy did not identify an increased risk of depression or other mental disorders among adolescents compared with other age groups. In contrast, the majority of studies conducted during the postpartum period identified an increased risk of depression in adolescents compared with other age groups. Three studies reported on mental health outcomes following abortion, with varying results. We found no studies of the effect of sexually transmitted infections on mental health among adolescents.ConclusionWe recommend that sexual and reproductive health services should be accessible to adolescents to address their needs and help to prevent any adverse mental health outcomes. 相似文献
When a new treatment regimen is expected to have comparable or slightly worse efficacy to that of the control regimen but has benefits in other domains such as safety and tolerability, a noninferiority (NI) trial may be appropriate but is fraught with difficulty in justifying an acceptable NI margin that is based on both clinical and statistical input. To overcome this, we propose to utilize composite risk‐benefit outcomes that combine elements from domains of importance (eg, efficacy, safety, and tolerability). The composite outcome itself may be analyzed using a superiority framework, or it can be used as a tool at the design stage of a NI trial for selecting an NI margin for efficacy that balances changes in risks and benefits. In the latter case, the choice of NI margin may be based on a novel quantity called the maximum allowable decrease in efficacy (MADE), defined as the marginal difference in efficacy between arms that would yield a null treatment effect for the composite outcome given an assumed distribution for the composite outcome. We observe that MADE: (1) is larger when the safety improvement for the experimental arm is larger, (2) depends on the association between the efficacy and safety outcomes, and (3) depends on the control arm efficacy rate. We use a numerical example for power comparisons between a superiority test for the composite outcome vs a noninferiority test for efficacy using the MADE as the NI margin, and apply the methods to a TB treatment trial. 相似文献
The Glycine tabacina polyploid complex has been shown to include a minimum of two morphological and crossing groups, which also differ in chloroplast DNA (cpDNA) restriction map and nuclear ribosomal gene repeat phenotype. These AAB2B2 and BBB2B2 G. tabacina polyploids contain plastomes referable to the A and B diploid plastome groups of subgenus Glycine, respectively. Eight different cpDNA variants were observed among the 65 B-type polyploids studied, six of which were identical for numerous restriction site characters to plastome types found among the highly polymorphic B genome diploid species. It is hypothesized that there have been numerous independent origins of polyploid G. tabacina: at least one AA x B2B2 event and a minimum of five BB x B2B2 events involving different BB types as female progenitor. Low amounts of cpDNA divergence between diploid and polyploid plastomes and among the plastomes of geographically disjunct polyploids suggest that the origin and dispersal of polyploids are relatively recent events. All hypothesized diploid progenitors are native to Australia, while both A- and B-type G. tabacina polyploids occur on islands of the Pacific outside the range of diploids. The presence of several different plastome types of polyploid G. tabacina in the Pacific islands suggests that several colonization events have occurred. 相似文献
Mycoplasma pneumoniae infection is a rare cause of acute nephritis. Six children (2 girls) aged 5–10 years, admitted for nephritis, had serological
tests showing recent Mycoplasma pneumoniae infection. The diagnosis of Mycoplasma pneumoniae infection was based on the presence of serum IgM, detected either by immunofluorescence (IF) (n=1) or enzyme-linked immunosorbent assay (n=5). Four children had a renal biospy, with analysis of parenchymal Mycoplasma pneumoniae components by indirect IF and polymerase chain reaction. Extrarenal symptoms were: respiratory (n=3), ear, nose, and throat (n=2), gastrointestinal (n=3), hepatic (n=1), neurological (n=1), articular (n=1), and hematological (n=3). The patients presented with acute nephritis (1 had a nephrotic syndrome) or with acute renal failure and proteinuria.
Pathological findings included type 1 membranoproliferative glomerulonephritis (MPGN, n=1), proliferative endocapillary glomerulonephritis (n=2), and minimal change disease (n=1). The patient with type 1 MPGN progressed rapidly towards end-stage renal failure because of a congenital solitary kidney.
Among the patients with endocapillary glomerulonephritis, 1 relapsed 6 months later and remained proteinuric, while the other
recovered, as did the child with minimal change disease. The search for Mycoplasma pneumoniae antigens and nucleic acids in renal tissue was negative. However, the absence of the microorganism in the kidney is a common
feature of post-streptococcal glomerulonephritis. We conclude that Mycoplasma pneumoniae is a rare yet potential cause of acute glomerulonephritis.

Substance abuse and violence among today's youth are at an all time high. Numerous prevention programs have been implemented to address these issues. Not all are successful. Research has found that when schools and communities are involved in the planning of prevention programs, youth are more cognizant of risk factors and of behaviors that strengthen risk factors. The purpose of this study was to assess the emerging needs for prevention and health education among youth, and to identify effective approaches for prevention program development and service delivery in schools and communities. This study surveyed 312 youth prevention specialists, school and community health educators and counselors, and parents in a regional sample of ten states. Results indicated that substance abuse and violence are the two most critical and priority issues in need of comprehensive prevention. Multiple prevention service delivery strategies appropriate to youth, including training, technical assistance, conferencing and networking, needs assessment and evaluation, and information requests are discussed in detail. Implications for prevention programming emphasized reducing risk factors and strengthening protective factors, reaching and motivating youth participation.相似文献
