Cost-effectiveness of Direct Transfer to Angiography Suite of Patients With Suspected Large Vessel Occlusion

BACKGROUND AND OBJECTIVES

Patients with acute ischemic stroke due to large vessel occlusion (LVO) deemed eligible for endovascular thrombectomy (EVT) are transferred from the emergency room to the angiography suite to undergo the procedure. Recently, the strategy of direct transfer of patients with suspected LVO to the angiography suite (DTAS) has been shown to improve functional outcomes. This study aims to evaluate the cost-effectiveness of the DTAS strategy vs initial transfer of patients with suspected LVO (Rapid Arterial Occlusion Evaluation score >4 and NIH Stroke Scale >10) to the emergency room (ITER).

METHODS

A decision-analytic Markov model was developed to estimate the cost-effectiveness of the DTAS strategy vs the ITER strategy from a Dutch health care perspective with a 10-year time horizon. The primary outcome was the incremental cost-effectiveness ratio (ICER) using Dutch thresholds of $59,135 (€50,000) and $94,616 (€80,000) per quality-adjusted life year (QALY). Uncertainty of input parameters was assessed using 1-way sensitivity analysis, scenario analysis, and probabilistic sensitivity analysis.

RESULTS

The DTAS strategy yielded 0.65 additional QALYs at an additional $16,089, resulting in an ICER of $24,925/QALY compared with the ITER strategy. The ICER varied from $27,169 to $38,325/QALY across different scenarios. The probabilistic sensitivity analysis showed that the DTAS strategy had a 91.8% and 97.0% likelihood of being cost-effective at a decision threshold of $59,135/QALY and $94,616/QALY, respectively.

DISCUSSION

The cost-effectiveness of the DTAS strategy over ITER is robust for patients with suspected LVO. Together with recently published clinical results, this means that implementation of the DTAS strategy may be considered to improve the workflow and outcome of EVT.

Cognitive Interviews of Vietnamese Americans on Healthy Eating and Physical Activity Health Educational Materials

The purpose of this study was to better understand if a health educational presentation using culturally adapted materials was understandable and culturally appropriate, and that the content was retained, in an older Vietnamese American population. This study used cognitive interviewing. A convenient sampling was used to recruit eight participants by staff of a community-based organization from its client base. This is the first study to document that family eating style poses a challenge for estimating food intake among Vietnamese Americans. Participants who ate in a family eating style were not able to recall or estimate the number of servings of protein and vegetables. Some older Vietnamese Americans used food for healing and self-adjusted portion sizes from dietary recommendations. Cognitive interviewing is a useful method to improve comprehension, retention, and cultural appropriateness of health educational materials. Further nutrition research concerning intake measurement in ethnic groups that practice a family eating style is warranted.

A mediation model of professional psychological help seeking for suicide ideation among Asian American and white American college students

This study examined professional psychological help seeking among 1,045 white American and Asian American students from 70 U.S. colleges and universities who had seriously considered attempting suicide. The authors found that Asian American college students had lower rates of professional psychological help seeking for their suicide ideation than White American college students. Guided by social network perspectives on professional psychological help seeking, the authors also tested mediators of this racial disparity. Relative to white Americans, Asian Americans were advised by fewer people (especially fewer family members) to seek professional help, which was, in turn, associated with lower rates of professional psychological help seeking for suicide ideation. These findings underscore the importance of gatekeeping as a suicide prevention strategy for Asian American college students.

The interpersonal shame inventory for Asian Americans: scale development and psychometric properties

This article reports the development and psychometric properties of the Interpersonal Shame Inventory (ISI), a culturally salient and clinically relevant measure of interpersonal shame for Asian Americans. Across 4 studies involving Asian American college students, the authors provided evidence for this new measure's validity and reliability. Exploratory factor analyses and confirmatory factor analyses provided support for a model with 2 correlated factors: external shame (arising from concerns about others' negative evaluations) and family shame (arising from perceptions that one has brought shame to one's family), corresponding to 2 subscales: ISI-E and ISI-F, respectively. Evidence for criterion-related, concurrent, discriminant, and incremental validity was demonstrated by testing the associations between external shame and family shame and immigration/international status, generic state shame, face concerns, thwarted belongingness, perceived burdensomeness, self-esteem, depressive symptoms, and suicide ideation. External shame and family shame also exhibited differential relations with other variables. Mediation findings were consistent with a model in which family shame mediated the effects of thwarted belongingness on suicide ideation. Further, the ISI subscales demonstrated high alpha coefficients and test-retest reliability. These findings are discussed in light of the conceptual, methodological, and clinical contributions of the ISI.

A latent profile analysis of Asian American men's and women's adherence to cultural values

The goal of this study was to identify diverse profiles of Asian American women's and men's adherence to values that are salient in Asian cultures (i.e., conformity to norms, family recognition through achievement, emotional self-control, collectivism, and humility). To this end, the authors conducted a latent profile analysis using the 5 subscales of the Asian American Values Scale-Multidimensional in a sample of 214 Asian Americans. The analysis uncovered a four-cluster solution. In general, Clusters 1 and 2 were characterized by relatively low and moderate levels of adherence to the 5 dimensions of cultural values, respectively. Cluster 3 was characterized by the highest level of adherence to the cultural value of family recognition through achievement, whereas Cluster 4 was typified by the highest levels of adherence to collectivism, emotional self-control, and humility. Clusters 3 and 4 were associated with higher levels of depressive symptoms than Cluster 1. Furthermore, Asian American women and Asian American men had lower odds of being in Cluster 4 and Cluster 3, respectively. These findings attest to the importance of identifying specific patterns of adherence to cultural values when examining the relationship between Asian Americans' cultural orientation and mental health status.

Coexistent choriocarcinoma and malignant mixed mesodermal tumor of the uterus

OBJECTIVE

The purpose of this article is to report a case of coexisting uterine choriocarcinoma and uterine malignant mixed mesodermal tumor (MMMT). The relevant literature is reviewed and possible pathogenesis discussed.

METHODS

The clinical course and histopathology of the case were reviewed and a Medline literature search for other cases was performed.

RESULTS

The patient's uterine tumor contained syncytiotrophoblastic and cytotrophoblastic cells that stained positively for the beta subunit of human chorionic gonadotrophin consistent with uterine choriocarcinoma. Pathology also revealed a second distinct neoplasm composed of adenocarcinoma admixed with sarcoma, compatible with a uterine MMMT. The patient experienced metastatic choriocarcinoma to her lungs, lymph nodes, and brain. She suffered a complicated clinical course and died 7 months after her initial diagnosis. The literature search revealed that various gynecologic and nongynecologic carcinomas with trophoblastic differentiation have been described, but an association with uterine MMMT has not been previously reported.

CONCLUSIONS

Trophoblastic differentiation and choriocarcinoma associated with gynecologic and nongynecologic tumors is rare. We document the presence of uterine MMMT coexisting with uterine choriocarcinoma that followed an aggressive clinical course and review the possible pathogenesis of this lesion.

Phosphorylation of protein kinase C-related kinase PRK2 during meiotic maturation of starfish oocytes

The resumption of meiosis in the developing starfish oocyte is the result of intracellular signaling events initiated by 1-methyladenine stimulation. One of the earliest detectable kinase activities during meiotic maturation of starfish oocytes is a protein kinase C or PKC-like activity. In this study, several isoforms of protein kinase C were cloned from the oocyte; however, the most abundant PKC-like maternal transcript corresponds to protein kinase C-related kinase 2 (PRK2). PRK2 is expressed in the immature oocyte and at least until germinal vesicle breakdown. Subcellular localization of PRK2 revealed a cytoplasmic distribution in the immature oocyte, which, during meiotic maturation, remained in the cytoplasm but also localized to the disintegrating germinal vesicle. Significantly, PRK2 is phosphorylated in vivo in response to 1-methyladenine which precedes MPF activation, making PRK2 a candidate regulator of early signaling events of meiotic maturation.
