RESUMO
It has been suggested that there may be an imbalance of excitation and inhibitory processes in the visual areas of the brain in people with migraine aura (MA). One idea is thalamocortical dysrhythmia, characterized by disordered oscillations, and thus disordered communication between the lateral geniculate nucleus and the cortex. Cross-orientation suppression is a visual task thought to rely on inhibitory processing, possibly originating in the lateral geniculate nucleus. We measured both resting-state oscillations and cross-orientation suppression using EEG over occipital areas in people with MA and healthy volunteers. We found evidence of cross-orientation suppression in the SSVEP responses, but no evidence of any group difference. Therefore, inhibitory processes related to cross-orientation suppression do not appear to be impaired in MA.
RESUMO
BACKGROUND: Although the pharmacokinetic profile of subcutaneous (SC) infliximab (IFX) is superior to conventional intravenous (IV) IFX, long-term efficacy and safety of SC IFX in patients with inflammatory bowel disease (IBD) have not been reported yet. This study aimed to evaluate long-term clinical outcomes of IBD patients treated with SC IFX compared with those of IBD patients treated with IV IFX during maintenance therapy. METHODS: This prospective cohort study enrolled 61 IBD patients in clinical remission who received scheduled IFX maintenance therapy. Of them, 38 patients were switched to SC IFX, while 23 patients continued IV IFX with dose optimization. Enrolled patients were followed up for 1 year. The primary outcome was durable remission defined as clinical remission (Crohn's disease, Harvey-Bradshaw index <5; ulcerative colitis, partial Mayo score <2) and biochemical remission (C-reactive protein <0.5 mg/dL) with IFX trough level ≥3 µg/mL throughout the follow-up period. RESULTS: One-year clinical remission, 1-year biochemical remission, and mucosal healing did not differ between the IV and SC IFX groups (n = 20 of 23 vs 33 of 38; Pâ =â 1.000; n = 22 of 23 vs 34 of 38; P = .641; and n = 10 of 18 vs 17 of 25; P = .414, respectively). During follow-up, the number of patients with IFX trough level <3 µg/mL was significantly lower in the SC IFX group (n = 0 of 38, 0%) than in the IV IFX group (n = 10 of 23, 43%) (P < .001). The SC IFX group showed higher 1-year durable remission than the IV IFX group (n = 31 of 38, 82% vs n = 11 of 23, 48%; P = .013). The incidence of IFX-related adverse events did not differ significantly between both groups (26% vs 39%; P = .446). CONCLUSION: The SC IFX switch induced a higher 1-year durable remission rate than continuing IV IFX in patients with IBD during scheduled maintenance therapy, showing similar safety.
Long-term efficacy and safety of subcutaneous infliximab in patients with inflammatory bowel diseases have not been reported yet. Switching from intravenous to subcutaneous infliximab showed higher 1-year durable remission than continuing intravenous infliximab during scheduled maintenance therapy, with similar safety.

BACKGROUND: Transgender persons are at high risk for HIV infection. Testing is a key component of the national effort to end the HIV epidemic in the United States. SETTING: Sixty-one local and state health departments and 150 community-based organizations funded by the Centers for Disease Control and Prevention to conduct HIV testing programs. METHODS: We analyzed HIV testing data submitted to the Centers for Disease Control and Prevention by funded health departments and community-based organizations during 2012-2017. Descriptive analysis examined patterns of HIV testing and key outcomes (diagnosis of HIV infection, linkage to HIV medical care, and interview for partner services) among transgender persons. Multivariate robust Poisson regression was used to assess associations between HIV testing outcomes and demographic characteristics, census region, and test setting. RESULTS: A total of 82,818 HIV tests were provided to transgender persons. Of these, 2280 (2.8%) transgender persons were diagnosed with HIV infection; 1556 (1.9%) received a new and 724 (0.9%) a previous diagnosis with HIV infection. The highest percentage of new HIV diagnosis was found among persons tested in correctional settings (4.6%), non-Hispanic Blacks (3.5%) and transgender women (2.4%). Among newly diagnosed persons, 85.0% were linked to HIV medical care ≤90 days after diagnosis and 63.5% were interviewed for partner services. CONCLUSIONS: HIV positivity was high, and the delivery of partner services was low, among transgender persons. HIV testing outcomes among transgender persons varied significantly by demographic characteristics and test setting. HIV prevention programs that are responsive to the needs of transgender persons may address gender-related disparities in HIV testing outcomes.

BACKGROUND: Allergic rhinitis (AR) is a worldwide health problem with rising prevalence. To enhance the estimation of AR prevalence in epidemiological studies, the Score for AR (SFAR), a screening tool, has been developed and widely used. An 8-item SFAR is a handy, self-administered instrument assessing the information on nasal and eye symptoms, seasonal increase in symptoms, skin test results, and previous AR diagnoses. This study aimed to adapt the SFAR to the Chinese population (CSFAR) and validate it by testing its psychometric properties and diagnostic accuracy. METHODS: This methodological study involved translation and validation phases. Different batches of participants were recruited for the above purposes. RESULTS: In phase 1, the CSFAR obtained satisfactory item (80-100%) and scale level (97.8%) semantic equivalence, content validity index (96.7%), comprehensibility (100%), cross-language testing (κ = 0.44-0.83 for item-to-item agreement; intraclass correlation coefficient [ICC] = 0.95, p < 0.05-0.001). In phase 2, CSFAR showed satisfactory internal consistency (α = 0.83), 1-month (ICC = 0.88) and 1-year stability (ICC = 0.85), and construct validity (significant correlation between CSFAR and impairments induced by AR: r = 0.47, p < 0.001). Based on the receiver-operating characteristic curve, comparing the CSFAR with diagnosis made by specialists, an optimal cutoff value was 6 (sensitivity 81.8% and specificity 80.3%). CONCLUSION: SFAR was translated into a Chinese version, the CSFAR. Satisfactory results were obtained for its equivalence, appropriateness, comprehensibility, and relevance, as well as its reliability and validity. A cutoff value of 6 was recommended to increase the diagnostic accuracy in environments with less pollen. This study provides evidence that the SFAR we adapted for the Chinese population is a valuable tool in AR screening.

OBJECTIVE: The Enhanced Comprehensive HIV Prevention Planning project was the first initiative of the Centers for Disease Control and Prevention (CDC) to address the goals of the National HIV/AIDS Strategy (NHAS). Health departments in 12 U.S. cities with a high prevalence of AIDS conducted comprehensive program planning and implemented cost-effective, scalable HIV prevention interventions that targeted high-risk populations. We examined trends in health department HIV prevention programs in these cities during the project. METHODS: We analyzed the number of people who received partner services, condoms distributed, and people tested for HIV, as well as funding allocations for selected HIV prevention programs by year and by site from October 2010 through September 2013. We assessed trends in the proportional change in services and allocations during the project period using generalized estimating equations. We also conducted thematic coding of program activities that targeted people living with HIV infection (PLWH). RESULTS: We found significant increases in funding allocations for HIV testing and condom distribution. All HIV partner services indicators, condom distribution, and HIV testing of African American and Hispanic/Latino populations significantly increased. HIV tests associated with a new diagnosis increased significantly among those self-identifying as Hispanic/Latino but significantly decreased among African Americans. For programs targeting PLWH, health department activities included implementing new program models, improving local data use, and building local capacity to enhance linkage to HIV medical care, retention in care, and treatment adherence. CONCLUSIONS: Overall, these findings indicate that health departments in areas with a high burden of AIDS successfully shifted their HIV prevention resources to scale up important HIV programs and make progress toward NHAS goals.

OBJECTIVES: To assess the association between state per capita allocations of Centers for Disease Control and Prevention (CDC) funding for HIV testing and the percentage of persons tested for HIV. SETTING AND PARTICIPANTS: We examined data from 2 sources: 2011 Behavioral Risk Factor Surveillance System and 2010-2011 State HIV Budget Allocations Reports. Behavioral Risk Factor Surveillance System data were used to estimate the percentage of persons aged 18 to 64 years who had reported testing for HIV in the last 2 years in the United States by state. State HIV Budget Allocations Reports were used to calculate the state mean annual per capita allocations for CDC-funded HIV testing reported by state and local health departments in the United States. DESIGN: The association between the state fixed-effect per capita allocations for CDC-funded HIV testing and self-reported HIV testing in the last 2 years among persons aged 18 to 64 years was assessed with a hierarchical logistic regression model adjusting for individual-level characteristics. MAIN OUTCOME: The percentage of persons tested for HIV in the last 2 years. RESULTS: In 2011, 18.7% (95% confidence interval = 18.4-19.0) of persons reported being tested for HIV in last 2 years (state range, 9.7%-28.2%). During 2010-2011, the state mean annual per capita allocation for CDC-funded HIV testing was $0.34 (state range, $0.04-$1.04). A $0.30 increase in per capita allocation for CDC-funded HIV testing was associated with an increase of 2.4 percentage points (14.0% vs 16.4%) in the percentage of persons tested for HIV per state. CONCLUSIONS: Providing HIV testing resources to health departments was associated with an increased percentage of state residents tested for HIV.

Although the percentage of overall AIDS diagnoses remains low among Asian and Pacific Islanders (APIs) in the United States compared with other racial/ethnic groups, research on API risk behaviors and health status suggest that the low number of AIDS cases may not provide a full picture of the epidemic and issues faced by this understudied and underserved population. Data from national HIV/AIDS surveillance systems and the Behavioral Risk Factor Surveillance System (BRFSS) were examined to delineate the magnitude and course of the HIV/AIDS epidemic among APIs in the United States. Same-sex sexual activity is the main HIV risk for API men, whereas heterosexual contact is for API women. APIs are significantly less likely to report being tested for HIV despite the fact that a similar proportion of APIs and other racial/ethnic groups reported having HIV risk in the past 12 months. Given the enormous diversity among APIs in the United States it is important to collect detailed demographic information to improve race/ethnicity and HIV risk classification, conduct better behavioral and disease monitoring for informing prevention planning, and addressing cultural, linguistic, economic and legal barriers to HIV prevention among APIs.

Accuracy of recall of the number of sexual partners individuals had over a period of one month, three months, six months and one year was studied in a group of 285 young, single, heterosexual adults. Self-reports of the number of partners were obtained on a weekly basis and then compared with recall of behavior over longer time periods that overlapped the weekly measures. For individuals who claimed abstinence or who claimed to be monogamous, accuracy of recall was relatively high, especially at the shorter time frames. Level of education was related to accuracy for claimed abstainers, such that lower levels of education were associated with lower accuracy of recall. Accuracy rates for individuals who reported having multiple sexual partners tended to be lower and were found to be related to one's propensity to engage in casual sex.

In December 1999 the Centers for Disease Control and Prevention's (CDC's) Division of HIV/AIDS Prevention initiated a standardized evaluation system for CDC-funded health department HIV prevention programs. This health department evaluation guidance asks health departments to develop comprehensive evaluation plans and to submit aggregated data on such activities as intervention planning, process monitoring, and outcome evaluation. During the first year of this system, of 65 health departments, 62 submitted evaluation plans, 37 submitted intervention plan data, and 20 submitted process monitoring data. Major issues affecting implementation of a national evaluation system include varying levels of evaluation capacity among health departments, differences between the CDC's taxonomy for national data collection and local definitions, and limitations regarding use of 1st-year data. The CDC has learned that implementation of a standardized evaluation system takes considerable time and that stakeholder involvement and technical assistance and capacity building support are essential.
