"Playing for Bragging Rights": A Qualitative Study of Students' Perceptions of Gamification.

BACKGROUND: Nursing faculty sought to promote students' engagement with course material and their peers by using Kaizen, an online educational game. The purpose of this qualitative study was to learn more about nursing students' perceptions of team competition in an educational game and whether the game promoted their engagement with educational material in one fundamental nursing course. METHOD: Qualitative data collection included focus groups, observations of students, documents showing leaderboards and game participation, and "status of competition" e-mails. Data were transcribed and coded to determine emerging themes. RESULTS: Four themes emerged from data analysis: learning in teams, motivators to play, learning course content, and suggestions for game improvement. CONCLUSION: Students were overwhelmingly positive about using a gamified platform for its educational rewards. They perceived that playing the game increased their knowledge retention, and they believed it helped them improve their test-taking skills. [J Nurs Educ. 2019;58(2):79-85.].

Hypothyroidism in Women.

Hypothyroidism, a disease in which the thyroid gland does not make enough thyroid hormone, is the second most common endocrine disorder among women. Symptoms of hypothyroidism include fatigue, weight gain, alteration in cognition, infertility, and menstrual abnormalities. The most common cause of hypothyroidism in the United States is Hashimoto's thyroiditis. The American Thyroid Association recommends an initial screening for thyroid disease at age 35years and every 5years thereafter. Thyroid-stimulating hormone is highly sensitive to thyroid dysfunction and is used to evaluate thyroid disorders. Monotherapy with levothyroxine is the standard for treating hypothyroidism. Diagnosing hypothyroidism requires appropriate diagnostic tests to facilitate prompt diagnosis and treatment.

Discharge planning rounds to the bedside: a patient- and family-centered approach.

Discharge planning rounds done at the bedside is an effective patient-centered approach to discharge planning and does not take any longer than traditional rounds apart from the patient and caregiver. Bedside rounds may decrease patient utilization of health care resources after discharge.

Accreditation: The hallmark of educational quality.

CONTEXT: Although accreditation issues have received attention over time, an accurate examination of accreditation has been absent within the radiologic science literature. OBJECTIVE: Using a literature review format, this review will define accreditation, provide a historical review of accreditation and purposes, identify the types of accreditation, discuss the major issues related to accreditation and explain how accreditation has affected the radiologic sciences. RESULTS: Although there is a great deal of rhetoric about accreditation in the radiologic sciences, research to support a particular type of accreditation within the radiologic sciences is absent. SUMMARY: Accreditation programs continuously are reviewed and changed, and accreditation organizations constantly strive to improve quality. In the past, the radiologic sciences have been influenced by accreditation decisions. The potential for future accreditation decisions affecting the radiologic sciences profession is possible.

Gene expression profiles in primary ovarian serous papillary tumors and normal ovarian epithelium: identification of candidate molecular markers for ovarian cancer diagnosis and therapy.

With the goal of identifying genes with a differential pattern of expression between ovarian serous papillary carcinomas (OSPCs) and normal ovarian (NOVA) epithelium and using this knowledge for the development of novel diagnostic and therapeutic markers for ovarian cancer, we used oligonucleotide microarrays with probe sets complementary to 12,533 genes to analyze the gene expression profiles of 10 primary OSPC cell lines, 2 established OSPC cell lines (UCI-101, UCI-107) and 5 primary NOVA epithelial cultures. Unsupervised analysis of gene expression data identified 129 and 170 genes that exhibited >5-fold upregulation and downregulation, respectively, in primary OSPC compared to NOVA. Genes overexpressed in established OSPC cell lines had little correlation with those overexpressed in primary OSPC, highlighting the divergence of gene expression that occurs as a result of long-term in vitro growth. Hierarchical clustering of the expression data readily distinguished normal tissue from primary OSPC. Laminin, claudin 3, claudin 4, tumor-associated calcium signal transducers 1 and 2 (TROP-1/Ep-CAM, TROP-2), ladinin 1, S100A2, SERPIN2 (PAI-2), CD24, lipocalin 2, osteopontin, kallikrein 6 (protease M), kallikrein 10, matriptase (TADG-15) and stratifin were among the most highly overexpressed genes in OSPC compared to NOVA. Downregulated genes in OSPC included transforming growth factor-beta receptor III, platelet-derived growth factor receptor alpha, SEMACAP3, ras homolog gene family member I (ARHI), thrombospondin 2 and disabled-2/differentially expressed in ovarian carcinoma 2 (Dab2/DOC2). Differential expression of some of these genes, including claudin 3, claudin 4, TROP-1 and CD24, was validated by quantitative RT-PCR and flow cytometry on primary OSPC and NOVA. Immunohistochemical staining of formalin-fixed, paraffin-embedded tumor specimens from which primary OSPC cultures were derived further confirmed differential expression of CD24 and TROP-1/Ep-CAM markers on OSPC vs. NOVA. These results, obtained with highly purified primary cultures of ovarian cancer, highlight important molecular features of OSPC and may provide a foundation for the development of new type-specific therapies against this disease.

Effect of blood transfusion during radiotherapy on the immune function of patients with cancer of the uterine cervix: role of interleukin-10.

PURPOSE: To analyze prospectively the effects of blood transfusion administered during radiotherapy (RT) on the immune function of patients with locally advanced cervical cancer. METHODS AND MATERIALS: In a total of 15 patients, 7 transfused and 8 untransfused, lymphocyte populations, including CD3+, CD4+, and CD8+ T-cell subsets, B cells (CD19+), and natural killer (NK) cells (CD56+, CD16+, CD3-) were studied before (i.e., time 0), during (i.e., times 1 and 2), and after (i.e., time 3) therapy. Expression of the early (CD25) and late (HLA-DR) activation markers on CD3+ T cells, the intracellular levels of perforin in CD8+ and CD56+ cells, and interferon (IFN)-gamma, interleukin (IL)-2, and IL-4 in CD4+ and CD8+ T cells were also measured. NK cell cytotoxicity against the NK-sensitive target K-562 cells and CD8+ T-cell-directed cytotoxicity against OKT3 hybridoma cells were also assessed. Finally, the plasma levels of the immunoregulatory cytokine IL-10 were analyzed by enzyme-linked immunosorbent assay. RESULTS: The mean absolute number of all lymphocyte subsets compared with pretreatment levels decreased significantly during RT of both transfused and untransfused patients (p >0.001), with no detectable differences between the two groups in terms of total lymphocytes or relative numbers of CD3+ and CD4+ T cells, CD56+ NK cells, or CD19+ B cells. In contrast, concomitant with an inversion of the CD4/CD8 ratio, a significant increase in the number of CD8+ T cells at time 2 and CD3+ T cells, CD8+ T cells, and NK cells at time 3 was found in the transfused patients compared with the untransfused group. The percentages of CD25+/CD3+ T cells and HLA-DR+/CD3+ T cells increased during RT of the untransfused patients, but CD3+ T cells showed decreased CD25 expression and increased HLA-DR expression in the transfused group. An increase of CD8+ IFN-gamma+ T cells with a concomitant decrease in CD8+ IL-2+ T cells was found in the transfused vs. untransfused group, and no differences were noted in the percentage of CD4+ IFN-gamma+ T cells and CD4+ IL-2+ T cells. The proportion of perforin-positive CD8+ and CD56+ cells was higher in the transfused group than in the untransfused group. However, CD56+ cells and CD8+ T cells from the transfused patients showed markedly diminished cytotoxic function. Finally, IL-10 was detected only in the plasma of the transfused patients. CONCLUSION: Blood transfusion during primary RT for cervical cancer profoundly alters the magnitude and characteristics of radiation-induced immunosuppression. Elevated serum IL-10 in transfused patients may play a role in the disregulation of lymphocyte function, in particular, the depression of NK- and T-cell cytotoxicity. Investigation of alternatives to blood transfusion during RT that do not diminish host immunity is warranted.

Overexpression of HER-2/neu in uterine serous papillary cancer.

PURPOSE: Uterine serous papillary carcinoma (USPC) is a highly aggressive variant of endometrial cancer and histologically similar to high-grade ovarian cancer. HER-2/neu, the transmembrane receptor encoded by the c-erbB2 gene, is overexpressed by immunohistology in approximately 25% of ovarian cancers. In this study, we have evaluated the expression of HER-2/neu in several fresh, established, paraffin-embedded, fixed USPCs. In addition, we have tested the sensitivity of USPC cells to Herceptin treatment. EXPERIMENTAL DESIGN: Ten consecutive USPC specimens were assessed by immunohistochemistry for the intensity of expression of HER-2/neu. In addition, three USPC cell lines were analyzed for expression of HER-2/neu by flow cytometry as well as for sensitivity to Herceptin-mediated, complement-dependent cytotoxicity, antibody-dependent cellular cytotoxicity (ADCC), and inhibition of cell proliferation. RESULTS: Eight of 10 (80%) of the USPCs assessed immunohistochemically for the intensity of expression of HER-2/neu stained heavily for HER-2/neu (2+ to 3+). Fresh and established primary USPC cell lines were found to express significantly more HER-2/neu receptor by flow cytometry (on the average, 10-fold greater) when compared with HER-2/neu-positive primary or established breast and ovarian cancer cell lines (P < 0.001). Importantly, although these USPC cell lines were resistant to chemotherapy in vivo and to natural killer- and complement-mediated cytotoxicity in vitro, they were found to be highly sensitive to Herceptin-mediated ADCC. USPC cell proliferation was also inhibited by Herceptin. A significant enhancement of ADCC was demonstrated when effector cells were exposed to low doses of IL-2 in vitro. Physiological concentrations of human serum IgG did not inhibit Herceptin-mediated ADCC against USPC. CONCLUSIONS: On the basis of these findings and previous reports showing a positive in vivo correlation between efficacy of Herceptin therapy and the level of HER-2/neu overexpression by tumor cells, we propose that Herceptin might be a novel and attractive therapeutic strategy in patients harboring chemotherapy-resistant, recurrent, or metastatic USPC.
