RESUMO
Romantic attachment is a popular theory for explaining affect, cognition, and behavior in romantic contexts. This popularity has led to a surge of self-report measures assessing dimensions of attachment. In this study, we considered the ability of 2 common attachment measures, the Adult Attachment Questionnaire (AAQ) and the Experience in Close Relationships-Revised (ECR-R), to replicate the avoidant and anxious attachment factors. We also determined the degree of measurement invariance across, and mean differences between, genders and single and nonsingle individuals. Both the AAQ (N = 650) and the ECR-R (N = 1,271) successfully distinguished avoidant and attachment factors. The AAQ showed evidence for partial strong measurement invariance, whereas the ECR-R showed strict factorial invariance for both gender and relationship status. Gender differences were detected on both measures in a direction consistent with previous research, with males exhibiting higher levels of avoidant attachment (relative to females) and females exhibiting higher levels of anxious attachment (relative to males). Furthermore, when compared to individuals who were currently single, those in romantic relationships exhibited lower levels of avoidant tendencies. This research aligns with the notion that the AAQ and ECR-R reliably assess similar constructs, across genders and single and nonsingle individuals.

BACKGROUND: In 2010, in the midst of the human immunodeficiency virus (HIV) epidemic in Zimbabwe, 69% of faculty positions in the Department of Medicine of the University of Zimbabwe College of Health Sciences (UZ-CHS) were vacant. To address the ongoing need to train highly skilled HIV clinicians with only a limited number of faculty, we developed and implemented a course for final-year medical students focused on HIV care using team-based learning (TBL) methods. METHODS: A competency-based HIV curriculum was developed and delivered to final-year medical students in 10 TBL sessions as part of a 12 week clinical medicine attachment. A questionnaire was administered to the students after completion of the course to assess their perception of TBL and self-perceived knowledge gained in HIV care. Two cohorts of students completed the survey in separate academic years, 2011 and 2012. Descriptive analysis of survey results was performed. RESULTS: Ninety-six of 120 students (80%) completed surveys. One hundred percent of respondents agreed that TBL was an effective way to learn about HIV and 66% strongly agreed. The majority of respondents agreed that TBL was more stimulating than a lecture course (94%), fostered enthusiasm for the course material (91%), and improved teamwork (96%). Students perceived improvements in knowledge gained across all of the HIV subjects covered, especially in challenging applied clinical topics, such as management of HIV antiretroviral failure (88% with at least a "large improvement") and HIV-tuberculosis co-infection (80% with at least a "large improvement"). CONCLUSIONS: TBL is feasible as part of medical education in an African setting. TBL is a promising way to teach challenging clinical topics in a stimulating and interactive learning environment in a low-income country setting with a high ratio of students to teachers.

Rapid automatized naming (RAN) has surged in popularity recently as an important indicator of reading difficulties, including dyslexia. Despite an extensive history of research on RAN, including recent meta-analyses indicating a unique contribution of RAN to reading above and beyond phonemic awareness, questions remain regarding RAN's relationship to reading. Specific questions exist regarding how PA mediates that relationship and how best to use data from RAN measures to identify risk for reading failure. Through multiple studies, we demonstrate that RAN is not merely subsumed by skills typically assessed when conducting universal screening for reading difficulties (i.e., phonemic segmentation fluency and letter naming fluency), but contributes unique information above and beyond these measures. Additionally, we discuss the process for the development of cut points for risk for Acadience RAN, along with guidance regarding how educators can interpret RAN scores as an indicator of risk for future reading difficulties. The results presented here support the idea that difficulties associated with RAN are not merely reflections of difficulties with other early literacy skills typically assessed during universal screening, but constitute separate and distinct difficulties that may precipitate later reading problems.
RESUMO
The human immunodeficiency virus (HIV) pandemic has amplified the global burden of tuberculosis (TB), particularly in sub-Saharan Africa, where 82% of the world's TB/HIV coinfection exists. HIV infection significantly increases the risk of developing and dying from TB and was associated with 350,000 TB deaths in 2010. The diagnosis of HIV-associated TB is often challenging due to atypical clinical and radiographic manifestations, more frequent extrapulmonary disease, and higher rates of smear-negative pulmonary TB. Nucleic acid amplification tests, including the Xpert MTB/RIF assay (Cepheid, Sunnyvale, CA), improve our ability to rapidly diagnose both smear-negative and extrapulmonary TB. The standard 6-month anti-TB regimen is usually adequate for HIV coinfected persons, but intermittent dosing in the intensive phase should be avoided because of an increased risk of relapse with acquired rifamycin resistance. The comanagement of HIV and TB is challenging due to drug-drug interactions, overlapping drug toxicities, concerns about adherence, and the immune reconstitution inflammatory syndrome. However, the initiation of antiretroviral therapy (ART) during the course of TB treatment is necessary to improve survival, and the appropriate timing of ART is dependent on the level of immune suppression. Therefore, the management of TB must be well coordinated with HIV resources, prepared to rapidly diagnose HIV, assess immune status, and correctly treat both infections.

The QuantiFERON-TB Gold In-Tube assay (QFT) is increasingly being used for latent tuberculosis screening in patients infected with human immunodeficiency virus (HIV) in the United States. This is a retrospective analysis of repeating positive QFT assays as a strategy to identify false-positive results in HIV-infected patients at low risk for tuberculosis.

In the spring of 2020, the Alaska Native Tribal Health Consortium (ANTHC) designed and built a sanitizing treatment system to address shortages of filtering facepiece respirators (FFRs). The design criteria included sanitizing large numbers of FFRs, repeatedly achieving FFR fit test requirements, and deactivating enveloped respiratory viruses, such as SARS-CoV-2. The outcome was the Mobile Sanitizing Trailer (MST), a 20 by 8-foot modified trailer designed to process up to 1,000 FFRs during a standard heat cycle. This paper reports on the MST's ability to: (1) sustain a target temperature, (2) produce tolerable conditions for FFRs as measured by fit factor and (3) successfully deactivate an infectious model virus. We found that the MST reliably and uniformly produced 75 degrees Celsius in the treatment chamber for the prescribed periods. Quantitative analysis showed that the FFRs achieved acceptable post-treatment fit factor even after 18, 60-minute heat cycles. Finally, the treated FFR materials had at least a log 3.0 reduction in viral RNA and no viable virus after 30, 60 or 90 minutes of heat treatment. As a sanitizing treatment during supply shortages, we found the MST a viable option for deactivation of virus and extending the usable life of FFRs.
