In this task, you are given an abstract of article. Your task is to generate label "True" if abstract is structured, otherwise generate "False". A structured abstract is composed of a topic sentence (or key sentence), relevant supporting sentences, and a closing (or transition) sentence. This structure is key to keeping your abstract focused on the main idea and creating a clear and concise image.

Q: Disadvantaged family socioeconomic status (SES) is often assumed to diminish parent training program effectiveness. In examining effects of SES, influences of initial problem severity have been largely ignored. In the present meta-analysis, we examined (a) whether there is a differential influence of SES on parent training effectiveness at immediate posttreatment and at 1-year follow-up-controlling for levels of initial problem severity--and (b) whether SES interacts with initial problem severity in its effect on program effectiveness. Seventy-five studies on parent training program effectiveness to reduce disruptive child behavior were included. Separate analyses were conducted for immediate posttreatment and approximately 1-year follow-up assessments. Immediately posttreatment, disadvantaged samples benefited less from parent training, but only when they had low levels of initial problem severity. At follow-up, disadvantaged samples benefited less from parent training regardless of initial problem severity. Initial problem severity was a strong predictor of effect sizes both immediately posttreatment and at follow-up. Parent training programs are equally effective for disadvantaged and nondisadvantaged families immediately posttreatment, at least when initial problems are severe. Maintenance of treatment gain, however, seems harder for disadvantaged families, suggesting that more sustained family support may be needed.

Q: BACKGROUND Cerebellar glioblastoma multiforme (cGBM) is rare, and although there is a general belief that these tumors have a worse prognosis than supratentorial GBM (sGBM), few studies have been published to support this belief.
OBJECTIVE To investigate the effect of cerebellar location on survival through a case-control design comparing overall survival time of cGBM and sGBM patients.
METHODS The Surveillance, Epidemiology, and End Results (SEER) registry was used to identify 132 patients with cGBM (1973-2008). Each cGBM patient was matched with an sGBM patient from among 20,848 sGBM patients on the basis of age, extent of resection, decade of diagnosis, and radiation therapy using propensity score matching.
RESULTS Within the cGBM, 37% were older than 65 years of age, 62% were men, and 87% were white. Most patients underwent surgery and radiation (74%), whereas only 26% underwent surgical resection only. The median survival time for the cGBM and sGBM matched cohort was 8 months; however, the survival distributions differed (log-rank P = .04). Survival time for cGBM vs sGBM at 2 years was 21.5% vs 8.0%, and 12.7% vs 5.3% at 3 years. Multivariate analysis of survival among cGBM patients showed that younger age (P < .0001) and having radiation therapy (P < .0001) were significantly associated with reduced hazard of mortality. Among all patients, multivariate analysis showed that tumor location (P = .03), age (P < .0001), tumor size (P = .009), radiation (P < .0001), and resection (P < .0001) were associated with survival time in the unmatched cohort.
CONCLUSION Median survival time for cGBM and sGBM patients was 8 months, but cGBM patients had a survival time advantage as the study progressed. These findings suggest that cGBM patients should be treated as aggressively as sGBM patients with surgical resection and radiation therapy.

Q: HIV causes a chronic infection characterized by depletion of CD4(+) T lymphocytes and the development of opportunistic infections. Despite drugs that inhibit viral spread, HIV infection has been difficult to cure because of uncharacterized reservoirs of infected cells that are resistant to highly active antiretroviral therapy (HAART) and the immune response. Here we used CD34(+) cells from infected people as well as in vitro studies of wild-type HIV to show infection and killing of CD34(+) multipotent hematopoietic progenitor cells (HPCs). In some HPCs, we detected latent infection that stably persisted in cell culture until viral gene expression was activated by differentiation factors. A unique reporter HIV that directly detects latently infected cells in vitro confirmed the presence of distinct populations of active and latently infected HPCs. These findings have major implications for understanding HIV bone marrow pathology and the mechanisms by which HIV causes persistent infection.
