Typical supervisor scripts and etiquette for help-provision involve indirect, soft correction strategies to build trainee self-entrustment. These scripts appear to be difficult to adapt appropriately to under-performing trainees. Importantly, supervisor scripts also promote patient entrustment, increasing the likelihood of patients returning to the trainee and training practice for subsequent review, which is a major mechanism for ensuring patient safety in general practice. Theories of entrustment in general practice training must account for the interplay between supervisor, trainee and patient entrustment processes, and work-related constraints. Gaps between entrustment as espoused in theory, and entrustment as enacted, may suggest limitations of entrustment theory when extended to the general practice context, and/or room for improvement in the oversight of trainee consultations in general practice training.Photodynamic therapy (PDT) is gradually becoming an alternative method in the treatment of several diseases. Here, we investigated the role of oxygen in photodynamically treated cervical cancer cells (HeLa). The effect of PDT on HeLa cells was assessed by exposing cultured cells to disulphonated zinc phthalocyanine (ZnPcS2) and tetrasulphonated zinc tetraphenylporphyrin (ZnTPPS4). Fluorescence microscopy revealed their different localizations within the cells. ZnTPPS4 seems to be mostly limited to the cytosol and lysosomes, whereas ZnPcS2 is most likely predominantly attached to membrane structures, including plasmalemma and the mitochondrial membrane. Phototoxicity assays of PDT-treated cells carried out under different partial pressures of oxygen showed dose-dependent responses. Interestingly, ZnPcS2 was also photodynamically effective at a minimal level of oxygen, under a nitrogen atmosphere. On the other hand, hyperbaric oxygenation did not lead to a higher PDT efficiency of either photosensitizer. Although both photosensitizers can induce a significant drop in mitochondrial membrane potential, ZnPcS2 has a markedly higher effect on mitochondrial respiration that was completely blocked after two short light cycles. In conclusion, our observations suggest that PDT can be effective even in hypoxic conditions if a suitable sensitizer is chosen, such as ZnPcS2, which can inhibit mitochondrial respiration.Purpose To date, it is not clear which anticancer agent is useful in combination with trastuzumab and pertuzumab As the first and second selective regimens for advanced or metastatic breast cancer (AMBC), this multicenter, open-label, phase II trial (JBCRG-M03 UMIN000012232) presents a prespecified analysis of eribulin in combination with pertuzumab and trastuzumab. Methods We enrolled 50 patients with no or single prior chemotherapy for HER2-positive AMBC during November 2013-April 2016. All patients received adjuvant or first-line chemotherapy with trastuzumab and a taxane. The treatment comprised eribulin on days 1 and 8 of a 21-day cycle and trastuzumabplus pertuzumab once every 3 weeks, all administered intravenously. While the primary endpoint was the progression-free survival (PFS), secondary endpoints were the response rate and safety. Results Of 50 patients, 49 were eligible for safety analysis, and the full analysis set (FAS) included 46 patients. We treated 8 (16%) and 41 (84%) patients in first- a Trial registration ID UMIN-CTR UMIN000012232.MET is a receptor tyrosine kinase known to drive neoplastic transformation and aggressive tumor phenotypes. Crizotinib is an oral multi-targeted tyrosine kinase inhibitor of MET, ALK, RON, and ROS1 kinases. In this study, the anticancer effects of crizotinib on breast cancer cells were investigated in vitro along with the molecular mechanisms associated with these effects. Besides, the antiproliferative effects of crizotinib in combination with chemotherapy, hormonal drugs, and targeted agents were examined. Results showed that crizotinib produced dose-dependent antiproliferative effects in BT-474 and SK-BR-3 breast cancer cells with IC50 values of 1.7 μM and 5.2 μM, respectively. Crizotinib inhibited colony formation of BT-474 cells at low micromolar concentrations (1-5 μM). Immunofluorescence and Western blotting indicated that crizotinib reduced total levels of MET and estrogen receptor (ERα) in BT-474 cells. Adaptaquin Also, crizotinib reduced the levels of phosphorylated (active) MET and HER2 in BT-474 cells. The combined treatment of crizotinib with doxorubicin and paclitaxel resulted in synergistic growth inhibition of BT-474 cells with combination index values of 0.46 and 0.35, respectively. Synergy was also observed with the combination of crizotinib with the hormonal drugs 4-hydroxytamoxifen and fulvestrant in BT-474 cells. Alternatively, the combination of crizotinib with lapatinib produced antagonistic antiproliferative effects in both BT-474 and SK-BR-3 cells. Collectively, these findings demonstrate the anticancer effects of crizotinib in breast cancer cells and reveal ERα as a potential therapeutic target of the drug apart from its classical kinase inhibitory activity. Crizotinib could be an appealing option in combination with chemotherapy or hormonal drugs for the management of breast cancer.

The multiple mini interview (MMI) has been incorporated into the holistic review process in the selection of students to US medical schools. The MMI has been used to evaluate interpersonal and intrapersonal attributes which are deemed as necessary for future physicians. We hypothesized that there would be little difference in overall MMI evaluation data compared with traditional interview ratings.

The University of North Carolina School of Medicine developed an interview process that included atraditional interview and MMI format during the 2019 admissions cycle. Evaluation data along with key demographic variables for 608 MD program applicants were analyzed using descriptive and inferential statistical analyses.

The MMI format slightly favored female over male applicants (p = 0.002) but did not select for or against applicants based on age, race/ethnicity, underserved/rural area upbringing, or indicators of disadvantage. Out of 608 applicants, 356 (59%) completed apost-interview survey in which the experience was positively rated.
