An Evaluation Study of a College Success Course as a Counseling Intervention
Community colleges are attracting many first generation minority students. A question often asked is how can a college, faculty, and staff promote student achievement, particularly to underrepresented groups? One of the courses required at a South Texas community college, serving a predominately Hispanic population, is a College Success Course. Courses such as these are designed to facilitate students in developing the necessary skills/a college. The study explored the perceptions of counselors and students regarding the effectiveness of a College Success Course as a counseling intervention and as it related to improved student skills and achievement. The study included a between interviews were conducted with six counselors who taught the College Success Course. The students that received the College Success Course intervention completed a personal skills survey with open-ended questions. The constant comparative method was utilized to analyze the additional qualitative data (Patton, 2002). The findings of the qualitative portion of the study indicated that the College Success Course was viewed overall by s effective counseling intervention to improve student success skills. Students completed Nelson and Low’s (2004) College Version Emotional Skills Assessment Process (ESAP). Descriptive statistics and a one (ANOVA) were completed to compare the posttest ESAP scores of the intervention groups in comparison with the control groups. The ANOVA was significant in the assertion scores only. Although the quantitative statistical significance was limited, t facilitating them in improving their study skills
Academic Health Collaborative of Worcester
The Academic Health Collaborative of Worcester (AHCW) is a formal partnership between local universities and the Worcester Division of Public Health (WDPH) to bridge academics and practice for the purpose of public health improvement. The mission of the ACHW is to foster collaboration between the WDPH, UMass Memorial Medical Center, and academic partners to improve community health and develop public health research and practice leaders. Current academic partners include Clark University, UMass Medical School, and Worcester State University. The collaborative allows the WDPH to work closely with faculty to create a study or project with student deliverables co-designed by faculty and WDPH staff to advance the strategic plan of the WDPH and the Community Health Improvement Plan. Successful AHCW workforce development initiatives have included internships, clerkships, consultancies, and service learning assistantships. Most recently, a consultant developed materials to improve the structure and capacity of the AHCW. Due to this work, we anticipate additional partners to join the AHCW in the coming months. Student education, workforce development, and practice-focused research make the AHCW uniquely positioned to improve the public\u27s health through an interdisciplinary approach. Through the collaborative, WDPH can leverage local expertise to help achieve its goal of becoming the healthiest city in New England by 2020
Computer Gaming and Student Achievement: Investigating Middle School Students’ Behaviors
In spite of very little research on the subject, a growing concern exists among professionals that excessive time spent by students on computer gaming may have an undesirable effect in scholastic achievement. In this study, middle grade students self-reported their time spent on computer gaming for a one week time period. These self-reports were related with their GPAs at the end of the semester. Analysis of 114 students’ GPAs in English, Math, and Science indicated the presence of a statistically significant difference in English GPAs between students in the High Computer Gaming group from students in the Moderate and Low Computer Gaming groups. No differences were yielded for Math or Science GPAs. Implications are discussed
Is it for generation me? A qualitative study exploring marketing and selling plants online to millennial-aged consumers
As online selling of products like living plants increases, it is increasingly important to understand how millennial-aged consumers perceive the purchasing experience. New-media technologies like social media, e-newsletters, and other forms of digital communication are easily adopted by millennial-aged consumers. One of these tools, 360-degree video, offers novel ways to preview products offered online and look inside local brick-and-mortar stores, which can be visited in person. Sales of horticultural goods online have been slow to be developed by industry veterans, creating ample opportunities available to new ventures. This qualitative study used a series of three focus groups to answer the research questions of RQ1: What challenges exist for garden centers attracting millennials? RQ2: What are millennials preferences for purchasing live plants online? RQ3: What aspects of digital online marketing influence millennials to make decisions? RQ4: What are millennials preferences for 360-degree video? Results of this study indicate 360-degree video is not the preferred avenue for marketing plants online to millennials, however, high-quality photos and video with educational content and the use of social media could be effective
Bioactive Recombinant Human Oncostatin M for NMR-Based Screening in Drug Discovery
Oncostatin M (OSM) is a pleiotropic, interleukin-6 family inflammatory cytokine that plays an important role in inflammatory diseases, including inflammatory bowel disease, rheumatoid arthritis, and cancer progression and metastasis. Recently, elevated OSM levels have been found in the serum of COVID-19 patients in intensive care units. Multiple anti-OSM therapeutics have been investigated, but to date no OSM small molecule inhibitors are clinically available. To pursue a high-throughput screening and structure-based drug discovery strategy to design a small molecule inhibitor of OSM, milligram quantities of highly pure, bioactive OSM are required. Here, we developed a reliable protocol to produce highly pure unlabeled and isotope enriched OSM from E. coli for biochemical and NMR studies. High yields (ca. 10 mg/L culture) were obtained in rich and minimal defined media cultures. Purified OSM was characterized by mass spectrometry and circular dichroism. The bioactivity was confirmed by induction of OSM/OSM receptor signaling through STAT3 phosphorylation in human breast cancer cells. Optimized buffer conditions yielded 1H, 15N HSQC NMR spectra with intense, well-dispersed peaks. Titration of 15N OSM with a small molecule inhibitor showed chemical shift perturbations for several key residues with a binding affinity of 12.2 ± 3.9 μM. These results demonstrate the value of bioactive recombinant human OSM for NMR-based small molecule screening
Sex differences in brain tumor glutamine metabolism reveal sex-specific vulnerabilities to treatment
BACKGROUND: Brain cancer incidence and mortality rates are greater in males. Understanding the molecular mechanisms that underlie those sex differences could improve treatment strategies. Although sex differences in normal metabolism are well described, it is currently unknown whether they persist in cancerous tissue.
METHODS: Using positron emission tomography (PET) imaging and mass spectrometry, we assessed sex differences in glioma metabolism in samples from affected individuals. We assessed the role of glutamine metabolism in male and female murine transformed astrocytes using isotope labeling, metabolic rescue experiments, and pharmacological and genetic perturbations to modulate pathway activity.
FINDINGS: We found that male glioblastoma surgical specimens are enriched for amino acid metabolites, including glutamine. Fluoroglutamine PET imaging analyses showed that gliomas in affected male individuals exhibit significantly higher glutamine uptake. These sex differences were well modeled in murine transformed astrocytes, in which male cells imported and metabolized more glutamine and were more sensitive to glutaminase 1 (GLS1) inhibition. The sensitivity to GLS1 inhibition in males was driven by their dependence on glutamine-derived glutamate for α-ketoglutarate synthesis and tricarboxylic acid (TCA) cycle replenishment. Females were resistant to GLS1 inhibition through greater pyruvate carboxylase (PC)-mediated TCA cycle replenishment, and knockdown of PC sensitized females to GLS1 inhibition.
CONCLUSION: Our results show that clinically important sex differences exist in targetable elements of metabolism. Recognition of sex-biased metabolism may improve treatments through further laboratory and clinical research.

Human cytomegalovirus in breast milk is associated with milk composition and the infant gut microbiome and growth
Human cytomegalovirus (CMV) is a highly prevalent herpesvirus that is often transmitted to the neonate via breast milk. Postnatal CMV transmission can have negative health consequences for preterm and immunocompromised infants, but any effects on healthy term infants are thought to be benign. Furthermore, the impact of CMV on the composition of the hundreds of bioactive factors in human milk has not been tested. Here, we utilize a cohort of exclusively breastfeeding full-term mother-infant pairs to test for differences in the milk transcriptome and metabolome associated with CMV, and the impact of CMV in breast milk on the infant gut microbiome and infant growth. We find upregulation of the indoleamine 2,3-dioxygenase (IDO) tryptophan-to-kynurenine metabolic pathway in CMV+ milk samples, and that CMV+ milk is associated with decreased Bifidobacterium in the infant gut. Our data indicate two opposing CMV-associated effects on infant growth; with kynurenine positively correlated, and CMV viral load negatively correlated, with infant weight-for-length at 1 month of age. These results suggest CMV transmission, CMV-related changes in milk composition, or both may be modulators of full-term infant development
Mammary molecular portraits reveal lineage-specific features and progenitor cell vulnerabilities.
The mammary epithelium depends on specific lineages and their stem and progenitor function to accommodate hormone-triggered physiological demands in the adult female. Perturbations of these lineages underpin breast cancer risk, yet our understanding of normal mammary cell composition is incomplete. Here, we build a multimodal resource for the adult gland through comprehensive profiling of primary cell epigenomes, transcriptomes, and proteomes. We define systems-level relationships between chromatin-DNA-RNA-protein states, identify lineage-specific DNA methylation of transcription factor binding sites, and pinpoint proteins underlying progesterone responsiveness. Comparative proteomics of estrogen and progesterone receptor-positive and -negative cell populations, extensive target validation, and drug testing lead to discovery of stem and progenitor cell vulnerabilities. Top epigenetic drugs exert cytostatic effects; prevent adult mammary cell expansion, clonogenicity, and mammopoiesis; and deplete stem cell frequency. Select drugs also abrogate human breast progenitor cell activity in normal and high-risk patient samples. This integrative computational and functional study provides fundamental insight into mammary lineage and stem cell biology
Examining sociodemographic correlates of opioid use, misuse, and use disorders in the All of Us Research Program
BACKGROUND: The All of Us Research Program enrolls diverse US participants which provide a unique opportunity to better understand the problem of opioid use. This study aims to estimate the prevalence of opioid use and its association with sociodemographic characteristics from survey data and electronic health record (EHR).
METHODS: A total of 214,206 participants were included in this study who competed survey modules and shared EHR data. Adjusted logistic regressions were used to explore the associations between sociodemographic characteristics and opioid use.
RESULTS: The lifetime prevalence of street opioids was 4%, and the nonmedical use of prescription opioids was 9%. Men had higher odds of lifetime opioid use (aOR: 1.4 to 3.1) but reduced odds of current nonmedical use of prescription opioids (aOR: 0.6). Participants from other racial and ethnic groups were at reduced odds of lifetime use (aOR: 0.2 to 0.9) but increased odds of current use (aOR: 1.9 to 9.9) compared with non-Hispanic White participants. Foreign-born participants were at reduced risks of opioid use and diagnosed with opioid use disorders (OUD) compared with US-born participants (aOR: 0.36 to 0.67). Men, Younger, White, and US-born participants are more likely to have OUD.
CONCLUSIONS: All of Us research data can be used as an indicator of national trends for monitoring the prevalence of receiving prescription opioids, diagnosis of OUD, and non-medical use of opioids in the US. The program employs a longitudinal design for routinely collecting health-related data including EHR data, that will contribute to the literature by providing important clinical information related to opioids over time. Additionally, this data will enhance the estimates of the prevalence of OUD among diverse populations, including groups that are underrepresented in the national survey data
