The number of clinical trials is rapidly growing, and automation of literature processing is becoming desirable but unresolved. Our purpose was to assess and increase the readiness of clinical trial reports for supporting automated retrieval and implementation in public health practice. We searched the Medline database for a random sample of clinical trials of HIV/AIDS management with likely relevance to public health in Africa.

The summer of 2020 marked a shift in public perception of police brutality and racism in the United States. Following the police murder of George Floyd and ensuing social unrest, the appropriate role and function of the police in communities have been a frequent topic of debate. Of particular concern is the intersection of policing and mental health where we see a pattern of police using excessive force disproportionately against persons with disabilities, especially mental health disabilities (Autistic Self Advocacy Network, 2017).

Our goal is to analyze improvement of scientific performance in a multidimensional outcome space, with a focus on US-based biomedical research. With the growing diversity of research databases, limiting assessment of scientific productivity to bibliometric measures such as number of publications, impact factor of journals and number of citations, is increasingly challenged. Using a wider range of outcomes, from publications through practice improvements to entrepreneurial outcomes, overcomes many current limitations in the study of research growth.

Despite evidence that racial and ethnic characteristics influence the impact of traumatic exposure on psychological health, little is known about how race and ethnic identity can alter, and possibly protect against, the effects of trauma on the psychiatric diagnoses of women. Therefore, the present study examined the moderating role of race/ethnicity and ethnic identity in the link between trauma exposure and psychiatric diagnosis for African American and Caucasian college women. Participants were a sample of 242 women from the Mid-Atlantic region of the United States who self-identified as African American or Black (31%) and European American or Caucasian (69%; age = 19.

Relatively little attention has been afforded to protective factors for community-level risks among non-urban populations. This study examined the extent to which traditional cultural attitudes and behaviors of 137 African American adolescents (ages 12-17) from a rural community moderated the relationship between perceived community disorganization and substance use behaviors. Results from hierarchical linear regression revealed that traditional cultural attitudes and behaviors were differentially related to community disorganization and adolescent substance use.

Transacting siRNA (tasiRNA) biogenesis in Arabidopsis is initiated by microRNA (miRNA) -guided cleavage of primary transcripts. In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment of RNA-DEPENDENT RNA POLYMERASE6 for dsRNA biosynthesis. An extensive screen for Arabidopsis mutants with specific defects in TAS3 tasiRNA biogenesis or function was done.

This brief report looks at the impact of discrimination, poverty and daily hassles on the stress and the subsequent health of African American women. Using this contextual framework, an Africentric, female-centered stress reduction program is presented to address the specific needs of this population. Thirty-three African American women between the ages of 22 and 63 participated in either an 8-h pilot of the proposed Africentric program or a 7-h standard stress reduction intervention.

Background/purpose: Fetal tracheal occlusion (TO) was developed in an attempt to enhance prenatal lung growth and improve survival in fetuses with severe congenital diaphragmatic hernia (CDH). We conducted a randomized, controlled clinical trial in 24 fetuses with severe left CDH (liver herniated into the thorax and low lung-to-head ratio) to compare survival after endoscopic fetal TO vs standard perinatal care (control) and prospectively followed up the 16 survivors (9 control, 7 TO) to compare neurodevelopmental, respiratory, surgical, growth, and nutritional outcomes.

Methods: At 1 and 2 years old, subjects underwent evaluation consisting of medical and neurological history and physical, developmental testing, nutritional assessment, oxygen saturation and pulmonary function testing, chest radiograph, and echocardiogram.

The objective of this study was to assess temporal lobe white matter (WM) quantitatively using T2 relaxometry in patients with pharmacologically intractable temporal lobe epilepsy (TLE). T2 relaxometry was performed using a dual-echo sequence with 23 contiguous oblique coronal slices in 56 consecutive TLE patients and in 30 healthy subjects. Averages of six slices were chosen to calculate T2 relaxation time in the temporal lobe WM (WM-T2) and the hippocampus (Hippo-T2).

The purpose of this study was to examine the relationship and combined influence of racial identity and Africentric values on African American children's psychosocial adjustment. Participants were 104 (53 males, 51 females) African American fourth-grade students attending an inner-city public school in a northeastern city. Child and teacher ratings were used to assess the relationship between racial identity, Africentric values, and several indices of child psychosocial adjustment, including child behavior control, school interest, and teacher perceptions of child strengths and problems in the classroom.

Objective: Non-contrast-enhanced magnetic resonance angiography (MRA) carotid imaging with the time-of-flight (TOF) technique compares favorably with angiography, ultrasound, and excised plaques. However, gadolinium contrast-enhanced MRA (CE-MRA) has almost universally replaced TOF-MRA, because it reduces imaging time (25 seconds vs 10 minutes) and improves signal-to-noise ratio. In our practice we found alarming discrepancies between CE-MRA and TOF-MRA, which was the impetus for this study.
