Although previous research identified predictors of violent events within violent heterosexual couples, findings were limited to the woman's reports, to her perceptions; his assessments were not obtained. This exploratory study was conducted to gain understanding of proximal predictors of violence assessed in "real-time" from the perspective of both partners. Fifteen adult heterosexual couples in which the woman reported experiencing partner violence in the prior 30 days were enrolled in a primary care clinic. Each partner provided separate daily telephone reports for eight weeks via an automated Interactive Voice Response (IVR), concerning the previous day's violence, alcohol use, stressors, emotional reactions and concerns for children. Same-day correlates were determined by Pearson correlations while prior-day predictors were identified via vector autoregression. Same-day correlations show that men's violence was associated with almost every other variable while women's violence correlated with men's violence, men's drug use, women's alcohol use, anger, closeness, hassles, and all men's negative feelings. Using prior-day predictors, men's violence was related to feelings (primarily hers), but women's violence was more dependent upon feelings of both of them as well as women's prior-day violence and alcohol use. Men's violence was dependent upon their partners' prior-day feelings and the men's lack of concern about effects of violence on children. Women's violence was also dependent upon women's prior-day feelings, as well as women's violence, alcohol use, marital closeness, and men's concern for children. Although the co-occurrence of men's and women's violence has been seen before, in this study only women's violence was linked to alcohol use.Background Palliative care is expanding as part of treatment, but remains underutilized in trauma settings. Palliative care consultations (PCC) have shown to reduce nonbeneficial, potentially inappropriate interventions (PII), as decision for their use should always be made in the context of both the patient's prognosis and the patient's goals of care. Objective To characterize trauma patients who received PCC and to analyze the effect of PCC and do-not-resuscitate (DNR) orders on PII in severely injured patients. Setting/Subjects Retrospective cohort study of 864 patients admitted to two level 1 trauma centers 432 patients who received PCC (PCC group) were compared with 432 propensity score match-controlled (MC group) patients who did not receive PCC. Measurements PCC in a consultative palliative care model, PII (including tracheostomy and percutaneous endoscopic gastrostomy) rate and timing, DNR orders. Results PCC rate in trauma patients was 4.3%, with a 5.3-day average time to PCC. PII were done in 9.0% of PCC and 6.0% of MC patients (p = 0.09). In the PCC group, 74.1% of PII were done before PCC, and 25.9% after. PCC compared with MC patients had significantly higher mechanical ventilation (60.4% vs. 18.1%, p  less then  0.001) and assisted feeding requirements (14.1% vs. 6.7%, p  less then  0.001). We observed a statistically significant reduction in PII after PCC (p = 0.002). Significantly less PCC than MC patients had PII following DNR (26.3% vs. 100.0%, p = 0.035). Conclusions PCC reduced PII in severely injured trauma patients by factor of two. Since the majority of PII in PCC patients occurred before PCC, a more timely administration of PCC is recommended. To streamline goals of care, PCC should supplement or precede a DNR discussion.Experimental manipulations in social psychology must exhibit construct validity by influencing their intended psychological constructs. Yet how do experimenters in social psychology attempt to establish the construct validity of their manipulations? Following a preregistered plan, we coded 348 experimental manipulations from the 2017 issues of the Journal of Personality and Social Psychology. Representing a reliance on "on-the-fly" experimentation, the vast majority of these manipulations were created ad hoc for a given study and were not previously validated before implementation. A minority of manipulations had their construct validity evaluated by pilot testing before implementation or via a manipulation check. Of the manipulation checks administered, most were face valid, single-item self-reports, and only a few met criteria for "true" validation. In aggregate, roughly two fifths of manipulations relied solely on face validity. To the extent that they are representative of the field, these results suggest that best practices for validating manipulations are not commonplace-a potential contributor to replicability issues. These issues can be remedied by validating manipulations before implementation using validated manipulation checks, standardizing manipulation protocols, estimating the size and duration of manipulations' effects, and estimating each manipulation's effects on multiple constructs within the target nomological network.Basal-like triple-negative breast cancers frequently express high levels of c-Myc. This oncoprotein signals to the core cell cycle machinery by impinging on cyclin E. High levels of E-type cyclins (E1 and E2) are often seen in human triple-negative breast tumors. In the current study, we examined the requirement for E-type cyclins in the c-Myc-driven mouse model of breast cancer (MMTV-c-Myc mice). 3MA To do so, we crossed cyclin E1- (E1-/-) and E2- (E2-/-) deficient mice with MMTV-c-Myc animals, and observed the resulting cyclin E1-/-/MMTV-c-Myc and cyclin E2-/-/MMTV-c-Myc females for breast cancer incidence. We found that mice lacking cyclins E1 or E2 developed breast cancers like their cyclin Ewild-type counterparts. In contrast, further reduction of the dosage of E-cyclins in cyclin E1-/-E2+/-/MMTV-c-Myc and cyclin E1+/-E2-/-/MMTV-c-Myc animals significantly decreased the incidence of mammary carcinomas, revealing arole for E-cyclins in tumor initiation. We also observed that depletion of E-cyclins in human triple-negative breast cancer cell lines halted cell cycle progression, indicating that E-cyclins are essential for tumor cell proliferation. In contrast, we found that the catalytic partner of E-cyclins, the cyclin-dependent kinase 2 (CDK2), is dispensable for the proliferation of these cells. These results indicate that E-cyclins, but not CDK2, play essential and rate-limiting roles in driving the proliferation of c-Myc overexpressing breast cancer cells.
