Understanding How Youth and Elders Form Relationships: A Study of Four Linking Lifetimes Programs

This report describes four projects established by the Temple University Center for Intergenerational Learning. It also uses the mentors' and youth's own words to delineate the various stages their relationships go through and the effects of different strategies on the development of positive relationships. The report includes an early attempt to correlate different mentoring approaches with their effects on relationship formation

Building Relationships With Youth in Program Settings: A Study of Big Brothers/Big Sisters

The success of mentoring programs often relies on ensuring that matched adults and youth meet long enough and often enough to establish a relationship that could generate positive changes for youth. This report draws on P/PV's research on program practices from Big Brothers/Big Sisters of America to provide a better understanding of mentoring relationships and their dynamics. Specifically, it provides insight into what helps good mentoring relationships to form, characteristics of good relationships and why they break up

Mentoring in the Juvenile Justice System: Findings from Two Pilot Programs

The final report on the pilot documents recruitment, operations, the activities of matched adults and youth and the characteristics of sustained matches. The pilot was not able to meet its goal of maintaining 100 matches over one year, and had limited success helping youth transition back to the community. Both results were attributed to the absence of a structure for recruiting, screening, training, supporting and supervising the mentors

Health-related quality of life in Black breast cancer survivors with and without triple-negative breast cancer (TNBC)

PurposeBlack women are more likely to develop early-onset (≤50 years) breast cancer (BC) and have the lowest five-year, cause-specific survival rate of any United States (U.S.) racial or ethnic group. These disparities can be attributed partially to the higher rate of triple-negative BC (TNBC) in Blacks. Yet, little is known about health-related quality of life (HRQOL) among Black women with TNBC.MethodsBlack women with invasive BC ≤ 50 years were recruited via the Florida Cancer Data System as part of a population-based case-only study of etiology and outcomes of early-onset invasive BC. Of 460 consented participants, a subset of 355 self-reported sociodemographic, clinical, and psychosocial variables. Descriptive analyses included participants with known TNBC (n = 85) or non-TNBC (n = 245) disease. Univariable and multivariable analyses were conducted to examine differences in factors associated with HRQOL.ResultsIn unadjusted analyses, TNBC participants had significantly lower FACT-B total scores (90.1 ± 27.9) compared to non-TNBC (98.5 ± 27.6) participants (p < 0.05). For the TNBC group, multivariable analyses indicated five individual-level, and three systemic-level factors explain 80% of the response variation in HRQOL. For the non-TNBC group, seven individual-level factors and three systemic-level factors account for 76% of the variation in HRQOL scores.ConclusionsCompared to Black women with non-TNBC, TNBC women have worse HRQOL. There are key individual and systemic-level factors that are unique to both groups. Findings can inform future HRQOL interventions to support young Black BC survivors

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu

Health-status outcomes with invasive or conservative care in coronary disease

BACKGROUND In the ISCHEMIA trial, an invasive strategy with angiographic assessment and revascularization did not reduce clinical events among patients with stable ischemic heart disease and moderate or severe ischemia. A secondary objective of the trial was to assess angina-related health status among these patients. METHODS We assessed angina-related symptoms, function, and quality of life with the Seattle Angina Questionnaire (SAQ) at randomization, at months 1.5, 3, and 6, and every 6 months thereafter in participants who had been randomly assigned to an invasive treatment strategy (2295 participants) or a conservative strategy (2322). Mixed-effects cumulative probability models within a Bayesian framework were used to estimate differences between the treatment groups. The primary outcome of this health-status analysis was the SAQ summary score (scores range from 0 to 100, with higher scores indicating better health status). All analyses were performed in the overall population and according to baseline angina frequency. RESULTS At baseline, 35% of patients reported having no angina in the previous month. SAQ summary scores increased in both treatment groups, with increases at 3, 12, and 36 months that were 4.1 points (95% credible interval, 3.2 to 5.0), 4.2 points (95% credible interval, 3.3 to 5.1), and 2.9 points (95% credible interval, 2.2 to 3.7) higher with the invasive strategy than with the conservative strategy. Differences were larger among participants who had more frequent angina at baseline (8.5 vs. 0.1 points at 3 months and 5.3 vs. 1.2 points at 36 months among participants with daily or weekly angina as compared with no angina). CONCLUSIONS In the overall trial population with moderate or severe ischemia, which included 35% of participants without angina at baseline, patients randomly assigned to the invasive strategy had greater improvement in angina-related health status than those assigned to the conservative strategy. The modest mean differences favoring the invasive strategy in the overall group reflected minimal differences among asymptomatic patients and larger differences among patients who had had angina at baseline

Initial invasive or conservative strategy for stable coronary disease

BACKGROUND Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. METHODS We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction. RESULTS Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, 121.8 percentage points; 95% CI, 124.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32). CONCLUSIONS Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used
