RESUMEN

Clear cell carcinomas are rare and relatively chemo-insensitive ovarian cancers with a characteristic molecular pathogenesis. Alterations in ARID1A, a component of the multiprotein chromatin remodeling complex SWI/SNF, are likely early events in the development of ovarian clear cancers arising from atypical endometriosis. Insight into additional driver events and particularly mutations in the same chromatin remodeling complex is limited. Isolated loss of SMARCA4, encoding the ATPase of the SWI/SNF complex, characterizes other aggressive gynecologic cancers including small cell carcinomas of the ovary hypercalcemic type (SCCOHT), undifferentiated endometrial carcinomas (UDEC), and uterine sarcomas (SDUS). The ovarian clear cell carcinoma of a 48-year-old showed in the initial surgical specimen a subclonal loss of SMARCA4 in addition to an ARID1A mutation, i.e., two alterations in the SWI/SNF heterochromatin remodeling complex. We anticipated that the SMARCA4 loss would worsen the disease course in analogy to SCCOHT, UDEC, and SDUS. However, the disease did not accelerate. Instead, the recurrent disease showed restored SMARCA4 expression while retaining the ARID1A mutation. Combinatorial redundancy, diversity and sequence in the SWI/SNF complex assembly as well as DNA- and tissue-specificity may explain the observed irrelevance of SMARCA4 loss in the presented ARID1A mutated ovarian clear cell carcinoma.

RESUMEN

Background: Depression and post-traumatic stress disorder (PTSD) are prevalent in pregnancy, especially among military members. These conditions can lead to adverse birth outcomes, yet, there's a paucity of evidence for prevention strategies. Optimizing physical fitness is one understudied potential intervention. We explored associations between prepregnancy physical fitness and antenatal depression and PTSD in soldiers. Materials and Methods: This was a retrospective cohort study of active-duty U.S. Army soldiers with live births between 2011 and 2014, identified with diagnosis codes from inpatient and outpatient care. The exposure was each individual's mean Army physical fitness score from 10 to 24 months before childbirth. The primary outcome was a composite of active depression or PTSD during pregnancy, defined using the presence of a code within 10 months before childbirth. Demographic variables were compared across four quartiles of fitness scores. Multivariable logistic regression models were conducted adjusting for potential confounders selected a priori. A stratified analysis was conducted for depression and PTSD separately. Results: Among 4,583 eligible live births, 352 (7.7%) had active depression or PTSD during pregnancy. Soldiers with the highest fitness scores (Quartile 4) were less likely to have active depression or PTSD in pregnancy (Quartile 4 vs. Quartile 1 adjusted odds ratio 0.55, 95% confidence interval 0.39-0.79). Findings were similar in stratified analyses. Conclusion: In this cohort, the odds of active depression or PTSD during pregnancy were significantly reduced among soldiers with higher prepregnancy fitness scores. Optimizing physical fitness may be a useful tool to reduce mental health burden on pregnancy.

RESUMEN

Sexual victimization of women by men on college campuses is a growing societal concern, with research identifying a host of situational and characterological factors that may predict men's likelihood to engage in sexual misconduct. In the present study, we examined the relative contribution and potential interplay of these various determinants on college men's perceptions of women's sexual desire and consent in hypothetical dating scenarios depicting a sexual interaction. We found that the men (N = 145) in this sample (a) conflated sexual desire with consent, (b) varied their appraisals of consent and desire depending on whether and how the woman in the vignette communicated consent or refusal, (c) perceived higher levels of consent if the man in the vignette had intercourse with the woman previously and as a function of escalating sexual intimacy in the ongoing interaction, (d) endorsed higher levels of perceived desire and consent across situations if they more strongly held rape-supportive attitudes, and (e) moderated their association between situational factors and perceptions of a woman's sexual intentions based on their endorsement of rape myths and a hypermasculine ideology. We conclude that efforts to prevent sexual violence among college students may benefit from being modeled on our findings that some men are likelier to infer consent regardless of the situation, that specific situational factors can foster misperceptions of consent across men in general, and that certain individuals in particular situations may pose the greatest risk for sexual misconduct.

RESUMEN

BACKGROUND: Per the Centers for Medicare and Medicaid Services (CMS) Code of Federal Regulations (CFR) 482.23(c) regarding medication administration, hospital policies and procedures must identify time-critical scheduled medications which must be administered within 30 minutes either before or after the scheduled dosing time, for a total administration window of 1 hour. OBJECTIVE: The general objective of this analysis was to determine whether there was a difference in meeting medication administration goals when comparing time-critical to non-time-critical scheduled medication administration in both intensive care units (ICUs) and general medical floors at a large, academic medical center. METHODS: Data were collected in 6 inpatient nursing units (3 general medical units and 3 ICUs) during the month of June 2017. Electronic medical record charge data for medications were used to evaluate timeliness of medication administration. RESULTS: In total, 69,794 medication administrations were evaluated. Of 389 administrations of time-critical scheduled medications, 268 (69%) were administered on time. Of 69,405 administrations of non-time-critical scheduled medications, 58,099 (84%) were administered on time (P < 0.001). ICUs had a higher percentage of on-time administrations than general medical units (89% vs 77%, P < 0.001), and nurses had a higher percentage of on-time administrations than respiratory therapists (84% vs 63%, P < 0.001). CONCLUSIONS: Non-time-critical scheduled medications were more commonly administered on time compared with time-critical scheduled medications. Staff education and optimizations to the electronic health record (EHR) are interventions that may improve administration of time-critical scheduled medications.

RESUMEN

Introduction: Cannabinoid hyperemesis syndrome (CHS) is a disorder of cyclic and recurrent nausea, vomiting, and abdominal pain associated with high-frequency and extended-duration marijuana use. Standard antiemetic therapy is often ineffective; however, capsaicin, an agonist of transient receptor potential vanilloid 1 (TRPV1), has shown promise in treating CHS.Methods: This retrospective cohort analysis evaluated the safety and efficacy of topical capsaicin for patients presenting with CHS. The primary outcome was to assess if utilization of capsaicin for ED management of CHS decreased ED length of stay (LOS) as compared to a visit without capsaicin. Secondary outcomes included a cost analysis, use of rescue therapies, and adverse events.Results: Forty-three patients met the inclusion criteria within the study period. ED LOS was reduced with capsaicin by a median of 22 minutes (201 vs. 179 min, p = 0.33). Patients received fewer additional medications if capsaicin was utilized (4 vs. 3 doses, p = 0.015), and 67% of visits where capsaicin was utilized required no further treatment prior to discharge. Additionally, opioid usage was less when utilizing capsaicin (166.5 vs. 69 mg OME). Forty-two percent of patients did not have a repeat CHS presentation to the ED after receiving capsaicin for an additional three months after the study period ended. Total medication cost was minimally more expensive (median difference of $3.26) in the capsaicin group. There were no significant adverse events reported with capsaicin.Conclusion: There was no significant difference in ED LOS when capsaicin was utilized for CHS. However, there was a decrease in total medications administered and a reduction in opioid requirements. While medication costs for capsaicin visits were minimally more expensive, the utility of capsaicin as an over-the-counter (OTC) product may empower at home therapy with OTC products, decreasing potentially unnecessary healthcare encounters and costs.

RESUMEN

BACKGROUND: Historically, steroids and endomyocardial biopsies have, respectively, been part of standard immunosuppression for preventing cardiac transplant rejection and monitoring for rejection. However, these treatments come with numerous adverse effects. Some transplant programs have questioned whether the risks and costs outweigh the benefits or whether they may interfere with patient outcomes. METHODS: Pediatric cardiac transplantations over 15 years (n = 49) were examined in a single-center retrospective study. Two groups of patients were formed: group 1 received induction steroids and underwent routine protocol biopsy (n = 18), and group 2 neither received steroids nor underwent routine biopsy (n = 13). RESULTS: The 1-year survival rate was similar between the two approaches: group 1 survival was 94% and group 2 survival was 92%. However, differences between the two groups were observed for comorbidities. Group 1 had 11 patients that exhibited rejection, and group 2 had only 1 patient (p = 0.003). Group 2 had fewer cases of posttransplant hypertension (p = 0.001) and insulin dependence (p = 0.02). CONCLUSIONS: This study suggests a less-invasive posttransplant approach that avoids biopsies and steroids was safely implemented in this single center. Both groups had similar survival. However, group 2 had statistically significant less posttransplant rejection, hypertension, and diabetes. Overall, this study shows no increased risk associated with steroid and biopsy avoidance in posttransplant patients, but with some clear benefits.

RESUMEN

The development of a pediatric cardiac support program is a complex, multidisciplinary project. This study describes the University of Iowa Congenital Heart Program's experience from its inception to the present. In, we examine those specific factors that have led to substantial improvements in the program, additionally identifying where further gains can be made. We retrospectively reviewed all pediatric patients who received mechanical cardiac support at the University of Iowa from the inception of the program in 1991. In total, 29 patients received mechanical support between December 1991 and December 2015 and are included in the study. Twelve patients received continuous flow devices and 17 patients received pulsatile flow devices. Median age at implant was 12.8 years (range 0.1-18.2 years). Median weight at implant was 40.5 kg (3.2-123.4 kg). Factors examined included: operating room (OR) time, intensive care unit and hospital length of stay, intubation days, blood product usage, pre- and post-operative bilirubin, creatinine, natriuretic peptide B (NPPB), and device implanted. Categorical and continuous variables were compared using Chi-squared and Wilcoxon rank-sum tests, respectively. Of the 29 patients who received mechanical support, 17 (58.6%) were discharged home, 11 (37.9%) died during their hospitalization, and 1 (3.5%) remains hospitalized. Median length of ventricular assist device support was 59.5 days (range 1-653 days). Between December 1991 and December 2011, in-hospital mortality was 64.3%. Following this period, significant changes were made to patient management with in-hospital mortality decreasing to 13.3% between February 2013 and December 2015. Comparison between deceased and living patients revealed several significant factors including: median number of packed red blood cells transfused, 8 versus 4 units (P = 0.048), median OR time, 396 versus 299 min (P = 0.003), and device implanted. During the early stages of the mechanical support program, higher than expected mortality rates prompted changes in the management of pediatric cardiac patients, specifically, the development of a dedicated management team. These changes significantly improved outcomes and we suggest can be used as a model for similar cardiac support programs, especially in smaller volume programs.

RESUMEN

Motor and sensory loss or dysfunction affects the quality of life for thousands of individuals daily. The upper limb, and especially the hand, are important for a person's ability to complete activities of daily living. Traditional therapy methods focus on motor recovery, but future methods should include sensory recovery and should promote the use of the affected limb(s) at home. In this review, we highlight the current state-of-art robotic devices for the upper limb, and we discuss benefits of including haptic feedback and virtual reality environments during neurorehabilitation. Robotic devices, such as end-effector devices, grounded and ungrounded exoskeletons, have been developed to assist with various functions including individual finger, whole hand, and shoulder movements. Many robots highlighted in this paper are inexpensive and are small enough to be in a patient's home, or allow for telerehabilitation. Virtual reality creates safe environments for patients to practice motor movements and interactive games improve enjoyment of therapy. Haptic feedback creates more immersive virtual reality, and contributes to the recovery of sensory function. Physiological studies conducted after brain trauma and with robotic devices contribute to the understanding of brain plasticity, and illustrate the efficacy of these technologies. We conclude by addressing the future direction of neurorehabilitation research.

RESUMEN

Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547-559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547-559, 2005).
