Regular tests for human papillomavirus (HPV) and early treatment could represent an important strategy for preventing anal cancers among men who have sex with men (MSM). This study investigated facilitators and barriers to take up clinician-collected and self-collected HPV tests among Chinese MSM. This study was based on the baseline sample of a longitudinal study promoting HPV vaccination among 350 Chinese MSM who had never received an HPV vaccination. The baseline survey was conducted from August 2019 to April 2020. The prevalence of any HPV tests uptake in lifetime was 19.1%; 4.9% had HPV infection in anus, genital, oral cavity, and other places. Among the participants, 20% and 76.8% intended to take up self-financed and free clinician-collected HPV tests, and 76.8% intended to use free self-collected HPV tests. After adjusting for significant background characteristics, perceived risk of HPV infection, and perceived benefits, barriers, cue to action, and self-efficacy related to HPV tests in general and/or specific to self-collected HPV tests were associated with behavioral intention to take up free clinician-collected and/or self-collected HPV tests. Less than 20% of Chinese MSM reported HPV tests uptake. Modifying perceptions related to HPV tests may be useful to increase HPV tests coverage in this group. 相似文献

PurposeTo examine the impact of targeted efforts to increase the number of female speakers at the Society of Interventional Radiology (SIR) Annual Scientific Meeting (ASM) by reporting gender trends for invited faculty in 2017/2018 vs 2016.Materials and MethodsFaculty rosters for the 2016, 2017, and 2018 SIR ASMs were stratified by gender to quantify female representation at plenary sessions, categorical courses, symposia, self-assessment modules, and “meet-the-expert” sessions. Keynote events, scientific abstract presentations, and award ceremonies were excluded. In 2017, the SIR Annual Meeting Committee issued requirements for coordinators to invite selected women as speakers. Session coordinators are responsible for issuing speaker invitations, and invited speakers have the option to decline.ResultsYears 2017 and 2018 showed increases in female speaker representation, with women delivering 13% (89 of 687) and 14% (85 of 605) of all assigned presentations, compared with 9% in 2016 (46 of 514; P = .03 and P = .01, respectively). Gender diversity correlated with the gender of the session coordinator(s). When averaged over a 3-year period, female speakers constituted 7% of the speaker roster (112 of 1,504 presentations) for sessions led by an all-male coordinator team, compared with 36% (108 of 302) for sessions led by at least 1 female coordinator (P < .0001). Results of the linear regression model confirmed the effect of coordinator team gender composition (P < .0001).ConclusionsHaving a woman as a session coordinator increased female speaker participation, which suggests that the inclusion of more women as coordinators is one mechanism for achieving gender balance at scientific meetings. 相似文献

Hepatitis B virus (HBV) can be found in ovarian tissues. This study compared HBV DNA levels in follicular fluid collected during oocyte retrieval with paired serum samples in HBV carriers after ovarian stimulation during IVF treatment for infertility. Sixty‐four HBV carrier women referred to the Assisted Reproductive Units of two Hong Kong hospitals were recruited. At oocyte retrieval, the follicular fluid aspirated from the first follicle was collected for study. In 22 women, the first follicular fluid sample from both ovaries was similarly collected and studied. These women were also tested for liver function test and HBeAg. In 28 (43.8%) women, HBV DNA was detected in follicular fluid and the level correlated with serum levels (Spearman's correlation P < .001). There was concordant detection of HBV DNA in both ovaries, and the levels were significantly correlated (Spearman's correlation P = .029). In 40% of women with FF HBV DNA, the follicular fluid:serum ratio was >1.0, suggesting stimulation of HBV replication. These women also had significantly different liver function test results. Increased HBV replication exists in 40% of women with HBV DNA detected in follicular undergoing ovarian stimulation during IVF treatment. 相似文献

Mental health hospitalization rates among U.S. children have been increasing locally and nationally in recent decades. Children in New York State (NYS) have also witnessed several collective traumatic events during the last two decades including the September 11, 2001, terrorist attacks (9/11), the Great Recession, and Hurricane Sandy (2012) and its aftermath. Decomposition of these rates into age, period, and cohort effects may help elucidate how large-scale collective traumatic events may be driving time trends. This study examined age–period–cohort effects in children and youth mental health hospitalizations in NYS from 1999–2013. Age effects followed a linear trend from age 5 years, B = −2.76, 95% CI [−3.48, −2.03)] up to age 15 years, B = 1.62, 95% CI [1.52, 1.73]. The largest period effects were noted in 2004, B = 0.36, 95% CI [0.28, 0.45], and in 2013, B = 0.31, 95% CI [0.15, 0.47], approximately 3 years after 9/11 and the Great Recession, respectively. The largest birth cohort effect was noted for children born in 1992–1995 (range: 0.29 for children born in 1992–0.27 for children born in 1995), suggesting that the birth cohorts who experienced the 9/11 attacks during middle childhood and the Great Recession during puberty are at increased risk of mental health hospitalizations compared to other birth cohorts. 相似文献

Viroporins are small, hydrophobic trans-membrane viral proteins that oligomerize to form hydrophilic pores in the host cell membranes. These proteins are crucial for the pathogenicity and replication of viruses as they aid in various stages of the viral life cycle, from genome uncoating to viral release. In addition, the ion channel activity of viroporin causes disruption in the cellular ion homeostasis, in particular the calcium ion. Fluctuation in the calcium level triggers the activation of the host defensive programmed cell death pathways as well as the inflammasome, which in turn are being subverted for the viruses’ replication benefits. This review article summarizes recent developments in the functional investigation of viroporins from various viruses and their contributions to viral replication and virulence. 相似文献

Immediate memory for “when,where and what”: Short‐delay retrieval using dynamic naturalistic material 下载免费PDF全文
We investigated the neural correlates supporting three kinds of memory judgments after very short delays using naturalistic material. In two functional magnetic resonance imaging (fMRI) experiments, subjects watched short movie clips, and after a short retention (1.5–2.5 s), made mnemonic judgments about specific aspects of the clips. In Experiment 1, subjects were presented with two scenes and required to either choose the scene that happened earlier in the clip (“scene‐chronology”), or with a correct spatial arrangement (“scene‐layout”), or that had been shown (“scene‐recognition”). To segregate activity specific to seen versus unseen stimuli, in Experiment 2 only one probe image was presented (either target or foil). Across the two experiments, we replicated three patterns underlying the three specific forms of memory judgment. The precuneus was activated during temporal‐order retrieval, the superior parietal cortex was activated bilaterally for spatial‐related configuration judgments, whereas the medial frontal cortex during scene recognition. Conjunction analyses with a previous study that used analogous retrieval tasks, but a much longer delay (>1 day), demonstrated that this dissociation pattern is independent of retention delay. We conclude that analogous brain regions mediate task‐specific retrieval across vastly different delays, consistent with the proposal of scale‐invariance in episodic memory retrieval.

ObjectiveTo assess recent cataract service delivery across communities of all sizes in Ontario.DesignRetrospective analysis of health records.ParticipantsAll Ontario Health Insurance Plan users.MethodsRaw physician Ontario Health Insurance Plan claims data for cataract surgery (E140A, E214A) from April 1, 2009, to March 31, 2014, were extracted from the Ontario Ministry of Health and Long-Term Care (MOHLTC) IntelliHealth database. Cataract surgery claims data were sorted by sex, by age, and by Ontario's 444 municipalities based on patient residence. Cataract surgery distribution was examined by population centre: Large Urban (≥100 000 persons), Medium (30 000–99 999 persons), Small (1000–29 999 persons), and Rural (<1000 persons) as defined by Statistics Canada. Wait times were extracted from the MOHLTC wait times database. Cataract surgery rate (CSR), defined as the number of cataract surgeries performed per million, was calculated.ResultsCataract surgery volumes remained unchanged from 2010 to 2014. Mean patient age was 71.6 ± 10 years. Patients lived in large urban (63%), medium (15%), small (21%), and rural (0.6%) communities. Mean wait times increased by 28% to 68.5 days, and 90th percentile wait times increased by 44% to 154.3 days. A reduction in CSR was observed among seniors aged 65–74 years (?10%) and 75+ years (?16%). Rural communities showed the largest decline (?19%). Among seniors aged ≥75 years, CSR declined the most for those living in rural communities (?25%).ConclusionsAdjusting the current government policy of zero-growth in cataract surgery volumes will support growing demands for cataract care in our aging population. 相似文献
