Objective: The objective of this study was to compare maternity leave satisfaction between physicians and nonphysicians. Currently, paid maternal leave is not guaranteed in the United States, resulting in palpable dissatisfaction among parents. Previous studies have shown associations between length of paid leave and career satisfaction and maternal happiness. Materials and Methods: A Qualtrics
® electronic survey was distributed to female professionals through email and social media from April 2019 to March 2020. Inclusion criterion was ≥1 child by birth or adoption, or active pregnancy. Continuous and categorical data were analyzed using two-sample t-test and chi-square, respectively. Results: Of 808 respondents, 77% were physicians. Mean age at birth/adoption of first child was higher in physicians versus nonphysicians (32.1 years vs. 29.7 years; p < 0.001). Physicians took shorter maternity leave than nonphysicians (10.9 weeks vs. 12.0 weeks, p = 0.017) with half of that time paid by employers (5.4 weeks vs. 5.9 weeks, p = 0.2). Dissatisfaction was high among physicians (85.1%) and nonphysicians (92.4%) that correlates with maternity leave compensation dissatisfaction (49% vs. 71.3%, p < 0.001). Thirty-four percent of physicians versus 41% of nonphysicians stated that their health was negatively impacted by maternity leave length. Physicians and nonphysicians reported similar incidences of depression, and breastfeeding, delivery, and other postpartum complications. When queried, 38.8% of physicians and 57% of nonphysicians said they would desire >16 weeks of paid maternity leave (p < 0.001). Conclusions: In conclusion, dissatisfaction among professional women on maternity leave duration and compensation is high in the United States. Given health implications for both mother and child, this should invite further discussion and changes. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Purpose: Hippocampus-avoidance whole brain radiotherapy with simultaneous integrated boost (HA-WBRT+SIB) is a complex treatment option for patients with multiple brain metastases, aiming to prevent neurocognitive decline and simultaneously increase tumor control. Achieving efficient hippocampal dose reduction in this context can be challenging. The aim of the current study is to present and analyze the efficacy of complete directional hippocampal blocking in reducing the hippocampal dose during HA-WBRT+SIB. Methods: A total of 30 patients with multiple metastases having undergone HA-WBRT+SIB were identified. The prescribed dose was 30 Gy in 12 fractions to the whole brain, with 98% of the hippocampus receiving ≤ 9 Gy and 2% ≤ 17 Gy and with SIB to metastases/resection cavities of 36–51 Gy in 12 fractions. Alternative treatment plans were calculated using complete directional hippocampal blocking and compared to conventional plans regarding target coverage, homogeneity, conformity, dose to hippocampi and organs at risk. Results: All alternative plans reached prescription doses. Hippocampal blocking enabled more successful sparing of the hippocampus, with a mean dose of 8.79 ± 0.99 Gy compared to 10.07 ± 0.96 Gy in 12 fractions with the conventional method (p < 0.0001). The mean dose to the whole brain (excluding metastases and hippocampal avoidance region) was 30.52 ± 0.80 Gy with conventional planning and 30.28 ± 0.11 Gy with hippocampal blocking (p = 0.11). Target coverage, conformity and homogeneity indices for whole brain and metastases, as well as doses to organs at risk were similar between planning methods (p > 0.003). Conclusion: Complete directional hippocampal blocking is an efficient method for achieving improved hippocampal sparing during HA-WBRT+SIB. [ABSTRACT FROM AUTHOR]

- Abstract
Background: All-trans retinoic acid (ATRA), a derivate of vitamin A, has been successfully used as a therapy to induce differentiation in M3 acute promyelocytic leukemia (APML), and has led to marked improvement in outcomes. Previously, attempts to use ATRA in non-APML in the clinic, however, have been underwhelming, likely due to persistent signaling through other oncogenic drivers. Dysregulated JAK/STAT signaling is known to drive several hematologic malignancies, and targeting JAK1 and JAK2 with the JAK1/JAK2 inhibitor ruxolitinib has led to improvement in survival in primary myelofibrosis and alleviation of vasomotor symptoms and splenomegaly in polycythemia vera and myelofibrosis. Objective: While dose-dependent anemia and thrombocytopenia limit the use of JAK2 inhibition, selectively targeting JAK1 has been explored as a means to suppress inflammation and STAT-associated pathologies related to neoplastogenesis. The objective of this study is to employ JAK1 inhibition (JAK1i) in the presence of ATRA as a potential therapy in non-M3 acute myeloid leukemia (AML). Methods: Efficacy of JAK1i using INCB52793 was assessed by changes in cell cycle and apoptosis in treated AML cell lines. Transcriptomic and proteomic analysis evaluated effects of JAK1i. Synergy between JAK1i+ ATRA was assessed in cell lines in vitro while efficacy in vivo was assessed by tumor reduction in MV-4-11 cell line-derived xenografts. Results: Here we describe novel synergistic activity between JAK1i inhibition and ATRA in non-M3 leukemia. Transcriptomic and proteomic analysis confirmed structural and functional changes related to maturation while in vivo combinatory studies revealed significant decreases in leukemic expansion. Conclusions: JAK1i+ ATRA lead to decreases in cell cycle followed by myeloid differentiation and cell death in human leukemias. These findings highlight potential uses of ATRA-based differentiation therapy of non-M3 human leukemia. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Barriers to research participation by racial and ethnic minority group members are multi-factorial, stem from historical social injustices and occur at participant, research team, and research process levels. The informed consent procedure is a key component of the research process and represents an opportunity to address these barriers. This manuscript describes the development of the Strengthening Translational Research in Diverse Enrollment (STRIDE) intervention, which aims to improve research participation by individuals from underrepresented groups. Methods: We used a community-engaged approach to develop an integrated, culturally, and literacy-sensitive, multi-component intervention that addresses barriers to research participation during the informed consent process. This approach involved having Community Investigators participate in intervention development activities and using community engagement studios and other methods to get feedback from community members on intervention components. Results: The STRIDE intervention has three components: a simulation-based training program directed toward clinical study research assistants that emphasizes cultural competency and communication skills for assisting in the informed consent process, an electronic consent (eConsent) framework designed to improve health-related research material comprehension and relevance, and a "storytelling" intervention in which prior research participants from diverse backgrounds share their experiences delivered via video vignettes during the consent process. Conclusions: The community engaged development approach resulted in a multi-component intervention that addresses known barriers to research participation and can be integrated into the consent process of research studies. Results of an ongoing study will determine its effectiveness at increasing diversity among research participants. [ABSTRACT FROM AUTHOR]

Introduction: The updated common rule, for human subjects research, requires that consents "begin with a 'concise and focused' presentation of the key information that will most likely help someone make a decision about whether to participate in a study" (Menikoff, Kaneshiro, Pritchard. The New England Journal of Medicine. 2017; 376(7): 613–615.). We utilized a community-engaged technology development approach to inform feature options within the REDCap software platform centered around collection and storage of electronic consent (eConsent) to address issues of transparency, clinical trial efficiency, and regulatory compliance for informed consent (Harris, et al. Journal of Biomedical Informatics 2009; 42(2): 377–381.). eConsent may also improve recruitment and retention in clinical research studies by addressing: (1) barriers for accessing rural populations by facilitating remote consent and (2) cultural and literacy barriers by including optional explanatory material (e.g., defining terms by hovering over them with the cursor) or the choice of displaying different videos/images based on participant's race, ethnicity, or educational level (Phillippi, et al. Journal of Obstetric, Gynecologic, & Neonatal Nursing. 2018; 47(4): 529–534.). Methods: We developed and pilot tested our eConsent framework to provide a personalized consent experience whereby users are guided through a consent document that utilizes avatars, contextual glossary information supplements, and videos, to facilitate communication of information. Results: The eConsent framework includes a portfolio of eight features, reviewed by community stakeholders, and tested at two academic medical centers. Conclusions: Early adoption and utilization of this eConsent framework have demonstrated acceptability. Next steps will emphasize testing efficacy of features to improve participant engagement with the consent process. [ABSTRACT FROM AUTHOR]

Objective: To discuss the study design and data analysis for three‐phase interrupted time series (ITS) studies to evaluate the impact of health policy, systems, or environmental interventions. Simulation methods are used to conduct power and sample size calculation for these studies. Methods: We consider the design and analysis of three‐phase ITS studies using a study funded by National Institutes of Health as an exemplar. The design and analysis of both one‐arm and two‐arm three‐phase ITS studies are introduced. Results: A simulation‐based approach, with ready‐to‐use computer programs, was developed to determine the power for two types of three‐phase ITS studies. Simulations were conducted to estimate the power of segmented autoregressive (AR) error models when autocorrelation ranged from −0.9 to 0.9 with various effect sizes. The power increased as the sample size or the effect size increased. The power to detect the same effect sizes varied largely, depending on testing level change, trend changes, or both. Conclusion: This article provides a convenient tool for investigators to generate sample sizes to ensure sufficient statistical power when three‐phase ITS study design is implemented.

Marine alginates are well established in wound management. Compared with different modern wound dressings, marine alginates cannot prove superior effects on wound healing. Alginates from bacteria have never been studied for medical applications so far, although the microbial polymer raises expectations for improved binding of wound factors because of its unique O-acetylation. Due to its possible positive effects on wound healing, alginates from bacteria might be a superior future medical product for clinical use. To prove the binding capacity of microbial alginates to pathophysiological factors in chronic wounds, we processed microbial alginate fibres, produced from fermentation of the soil bacterium Azotobacter vinelandii ATCC 9046, into needle web dressings and compared them with commercial dressings made of marine alginate. Four dressings were assessed: Marine alginate dressings containing either ionic silver or zinc/manganese/calcium, and microbial alginate dressings with and without nanosilver. All dressings were tested in an in vitro approach for influence on chronic wound parameters such as elastase, matrix metalloproteases-2, tumour necrosis factor-α, interleukin-8, and free radical formation. Despite the alginate origin or addition of antimicrobials, all dressings were able to reduce the concentration of the proinflammatory cytokines TNF-α and IL-8. However, microbial alginate was found to bind considerable larger amounts of elastase and matrix metalloproteases-2 in contrast to the marine alginate dressings. The incorporation of zinc, silver or nanosilver into alginate fibres did not improve their binding capacity for proteases or cytokines. The addition of nanosilver slightly enhanced the antioxidant capacity of microbial alginate dressings, whereas the marine alginate dressing containing zinc/manganese/calcium was unable to inhibit the formation of free radicals. The enhanced binding affinity by microbial alginate of Azotobacter vinelandii to pathophysiological factors may be interesting to support optimal conditions for wound healing. [ABSTRACT FROM AUTHOR]

MYELOID leukemia ,APOPTOSIS ,GENETIC overexpression ,PROTEIN expression ,RNA interference - Abstract
Myeloid cell leukemia 1 ( Mcl-1) is an antiapoptotic member of the Bcl-2 family of proteins that when overexpressed is associated with high tumor grade, poor survival, and resistance to chemotherapy. Mcl-1 is amplified in many human cancers, and knockdown of Mcl-1 using RNAi can lead to apoptosis. Thus, Mcl-1 is a promising cancer target. Here, we describe the discovery of picomolar Mcl-1 inhibitors that cause caspase activation, mitochondrial depolarization, and selective growth inhibition. These compounds represent valuable tools to study the role of Mcl-1 in cancer and serve as useful starting points for the discovery of clinically useful Mcl-1 inhibitors.

- Abstract
Summary Bromodomain and extra-terminal domain (BET) family inhibitors offer an approach to treating hematological malignancies. We used precision nuclear run-on transcription sequencing (PRO-seq) to create high-resolution maps of active RNA polymerases across the genome in t(8;21) acute myeloid leukemia (AML), as these polymerases are exceptionally sensitive to BET inhibitors. PRO-seq identified over 1,400 genes showing impaired release of promoter-proximal paused RNA polymerases, including the stem cell factor receptor tyrosine kinase KIT that is mutated in t(8;21) AML. PRO-seq also identified an enhancer 3′ to KIT. Chromosome conformation capture confirmed contacts between this enhancer and the KIT promoter, while CRISPRi-mediated repression of this enhancer impaired cell growth. PRO-seq also identified microRNAs, including MIR29C and MIR29B2 , that target the anti-apoptotic factor MCL1 and were repressed by BET inhibitors. MCL1 protein was upregulated, and inhibition of BET proteins sensitized t(8:21)-containing cells to MCL1 inhibition, suggesting a potential mechanism of resistance to BET-inhibitor-induced cell death.

The discovery of JAK2
V617F a decade ago led to optimism for a rapidly developing treatment revolution in Ph- myeloproliferative neoplasms. Unlike BCR-ABL, however, JAK2 was found to have a more heterogeneous role in carcinogenesis. Therefore, for years, development of new therapies was slow, despite standard treatment options that did not address the overwhelming symptom burden in patients with primary myelofibrosis (MF), post-essential thrombocythemia MF, post-polycythemia vera MF, and myelodysplastic syndrome (MDS)/ myeloproliferative neoplasm (MPN) syndromes. JAK-STAT inhibitors have changed this, drastically ameliorating symptoms and ultimately beginning to show evidence of impact on survival. Now, the genetic foundations of myelofibrosis and MDS/MPN are rapidly being elucidated and contributing to targeted therapy development. This has been empowered through updated response criteria for MDS/MPN and refined prognostic scoring systems in these diseases. The aim of this article is to summarize concisely the current and rationally designed investigational therapeutics directed at JAK-STAT, hedgehog, PI3K-Akt, bone marrow fibrosis, telomerase, and rogue epigenetic signaling. The revolution in immunotherapy and novel treatments aimed at previously untargeted signaling pathways provides hope for considerable advancement in therapy options for those with chronic myeloid disease.

In 2003,Laricobius nigrinusFender was introduced into the eastern United States as a biological control agent of the hemlock woolly adelgid (Adelges tsugaeAnnand). Following its release, it was discovered thatL. nigrinuswas hybridising and producing viable progeny withLaricobius rubidusLeConte, a species native to eastern North America. Recently,Laricobius osakensisMontgomery and Shiyake was imported from Japan into the USA as a potential biological control agent of hemlock woolly adelgid. Hybridisation betweenL. nigrinusandL. rubidusled to interest in the outcome of interactions betweenL. osakensisand the other twoLaricobiusspp. The purpose of this study was to determine ifL. osakensiscould mate withL. nigrinus, if they could produce hybrid progeny, and whether mating interferes with reproductive output.Laricobiusspp. were observed mating directly following emergence and found to be capable of producing sterile eggs in the absence of a mating event. Laboratory and confined field studies found no evidence thatL. osakensisandL. nigrinuscould produce hybrid progeny and the interaction between the two species did not result in a lower reproduction associated with interspecific mating attempts. Interbreeding should therefore not have an impact on biological control using these species. Fecundity experiments showed thatL. osakensisproduced eggs earlier in the season and at a higher rate thanL. nigrinus, suggesting thatL. osakensismay have the potential to be an even more successful biological control agent thanL. nigrinus.

- Abstract
Female pelvic anatomy can be a conceptual challenge. To understand the function of the pelvis, one must understand the basic anatomy and then the dynamic nature of the structures that allow for urinary and bowel continence in a variety of circumstances. An understanding of normal anatomy and function provides the clinician with a framework for understanding the pathophysiology of pelvic organ prolapse and female urinary incontinence. The evaluation of female urinary incontinence often involves the recognition and treatment of concurrent pelvic abnormalities, such as cystocele, uterine prolapse, enterocele, rectocele, or perineal laxity. The factors responsible for pelvic floor relaxation rarely affect isolated anatomic areas. This chapter provides a detailed description of normal female pelvic anatomy, and an emphasis is placed on key surgical landmarks for reestablishing normal anatomy. [ABSTRACT FROM AUTHOR]

Objective: To determine whether the rates of nontraumatic dental condition (NTDC)-related emergency department (ED) visits are higher during the typical working hours of dental offices and lower during night hours, as well as the associated factors. Methods: We analyzed data from the National Hospital Ambulatory Medical Care Survey for 1997 through 2007 using multivariate binary and polytomous logistic regression adjusted for survey design to determine the effect of predictors on specified outcome variables. Results: Overall, 4,726 observations representing 16.4 million NTDC-related ED visits were identified. Significant differences in rates of NTDC-related ED visits were observed with 40%-50% higher rates during nonworking hours and 20% higher rates on weekends than the overall average rate of 170 visits per hour. Compared with 19-33 year olds, subjects ,18 years old had significantly higher relative rates of NTDC-related ED visits during nonworking hours [relative rate ratio (RRR) = 1.6 to 1.8], whereas those aged 73 and older had lower relative rates during nonworking hours (RRR = 0.4; overall P = 0.0005). Compared with those having private insurance, Medicaid and self-pay patients had significantly lower relative rates of NTDC visits during nonworking and night hours (RRR = 0.6 to 0.7, overall P , 0.0003). Patients with a dental reason for visit were overrepresented during the night hours (RRR = 1.3; overall P = 0.04). Conclusion: NTDC-related visits to ED occurred at a higher rate during nonworking hours and on weekends and were significantly associated with age, patient-stated reason for visit and payer type.

Introduction and hypothesis: We compared the operative and immediate postoperative experience of the trocar-based Prolift® and non-trocar-based Elevate® techniques used to repair vaginal prolapse. Methods: A retrospective review of Prolift and Elevate repairs was performed. Baseline characteristics and operative and postoperative variables evaluated included compartment(s) repaired, adjacent organ injury, operative time (OT), change in hemoglobin (ΔH), pain score, narcotic use, length of stay (LOS), and short-term complications. Categorical variables were assessed as counts and percent frequency. Data were compared using chi-squared analysis and paired t test. Results: Prolift ( n = 143) and Elevate ( n = 77) patients were similar in age ( p = 0.19). Concurrent hysterectomy was done in 22 (15.4 %) and 24 (31.2 %), respectively, and concurrent midurethral sling placed in 100 (70 %) and 50 (65 %), respectively. LOS (median, 25th,75th) after anterior/apical compartment repairs was shorter with Elevate, whether with (1.0; 1.0,1.5 vs. 2.0 days;1.0, 2.0; p = 0.003) or without (2.0; 1.0, 2.0 vs. 2.0 days; 2.0, 3.0; p = 0.024) hysterectomy, but no differences in OT, ΔH, pain score, or narcotic use occurred. Posterior compartment mean pain scores were lower with Prolift (3.6 ± 2.2 vs. 1.7 ± 1.5, p = 0.035), and three-compartment-repair pain scores were lower with Elevate (0.6 ± 1.3 vs 2.5 ± 1.9; p = 0.013). Three bladder injuries occurred with Prolift but none with Elevate. Conclusions: Operative and postoperative experiences were similar between groups; however, Elevate anterior/apical repairs had shorter LOS, which might reflect more aggressive discharge planning. There were no bowel or major vascular injuries, and the Prolift trocar bladder injuries did not alter the surgical procedure. [ABSTRACT FROM AUTHOR]

The t(8;21) and t(16;21) that are associated with acute myeloid leukaemia disrupt two closely related genes termed Myeloid Translocation Genes 8 (MTG8) and 16 (MTG16), respectively. Many of the transcription factors that recruit Mtg16 regulate haematopoietic stem and progenitor cell functions and are required to maintain stem cell self-renewal potential. Accordingly, we found that Mtg16-null bone marrow (BM) failed in BM transplant assays. Moreover, when removed from the animal, Mtg16-deficient stem cells continued to show defects in stem cell self-renewal assays, suggesting a requirement for Mtg16 in this process. Gene expression analysis indicated that Mtg16 was required to suppress the expression of several key cell-cycle regulators including E2F2, and chromatin immunoprecipitation assays detected Mtg16 near an E2A binding site within the first intron of E2F2. BrdU incorporation assays indicated that in the absence of Mtg16 more long-term stem cells were in the S phase, even after competitive BM transplantation where normal stem and progenitor cells are present, suggesting that Mtg16 plays a role in the maintenance of stem cell quiescence.

Medical Education 2011: : 166-175 Academic medical centres may adopt new learning technologies with little data on their effectiveness or on how they compare with traditional methodologies. We conducted a comparative study of student reflective writings produced using either an electronic (blog) format or a traditional written (essay) format to assess differences in content, depth of reflection and student preference. Students in internal medicine clerkships at two US medical schools during the 2008-2009 academic year were quasi-randomly assigned to one of two study arms according to which they were asked to either write a traditional reflective essay and subsequently join in faculty-moderated, small-group discussion ( n = 45), or post two writings to a faculty-moderated group blog and provide at least one comment on a peer's posts ( n = 50). Examples from a pilot block were used to refine coding methods and determine inter-rater reliability. Writings were coded for theme and level of reflection by two blinded authors; these coding processes reached inter-rater reliabilities of 91% and 80%, respectively. Anonymous pre- and post-clerkship surveys assessed student perceptions and preferences. Student writing addressed seven main themes: (i) being humanistic; (ii) professional behaviour; (iii) understanding caregiving relationships; (iv) being a student; (v) clinical learning; (vi) dealing with death and dying, and (vii) the health care system, quality, safety and public health. The distribution of themes was similar across institutions and study arms. The level of reflection did not differ between study arms. Post-clerkship surveys showed that student preferences for blogging or essay writing were predicted by experience, with the majority favouring the method they had used. Our study suggests there is no significant difference in themes addressed or levels of reflection achieved when students complete a similar assignment via online blogging or traditional essay writing. Given this, faculty staff should feel comfortable in utilising the blog format for reflective exercises. Faculty members could consider the option of using either format to address different learning styles of students. [ABSTRACT FROM AUTHOR]

- Abstract
The roundheaded pine beetle (Dendroctonus adjunctus Blandford [Coleoptera: Curculionidae, Scolytinae]) is an aggressive (tree-killing) bark beetle species that attacks several species of pine. Characteristics of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) trees chosen for attack by this beetle were studied in a current outbreak in northern Arizona. We found significant differences in basal area increment, crown width, lengths of internodes, subbranches, and needles, phloem thickness, and resin composition between attacked and unattacked trees. Attacked trees had significantly lower basal area increment and internode and needle lengths but longer subbranch lengths at the top of the crown and longer crown widths. Attacked trees also had thicker phloem and contained a significantly higher percentage of α-pinene in resin, but a lower percentage of longifolene than unattacked trees. A baited tree experiment showed that attacks by the roundheaded pine beetle did not affect resin composition through time. Overall, our results suggest that host selection by the roundheaded pine beetle may not be random and that tree growth characteristics and resin composition are probably important factors in host selection.

Context: Research suggests that pharmaceutical marketing influences prescribing and may cause cognitive dissonance for prescribers. This work has primarily been with physicians and physician-trainees. Questions remain regarding why prescribers continue to meet with pharmaceutical representatives (PRs).Objective: To describe the reasons that prescribers from various health professions continue to interact with PRs despite growing evidence of the influence of these interactions.Design, Setting, and Participants: Multi-disciplinary focus groups with 61 participants held in practice settings and at society meetings.Results: Most prescribers participating in our focus groups believe that overall PR interactions are beneficial to patient care and practice health. They either trust the information from PRs or feel that they are equipped to evaluate it independently. Despite acknowledgement of study findings to the contrary, prescribers state that they are able to effectively manage PR interactions such that their own prescribing is not adversely impacted. Prescribers describe few specific strategies or policies for these interactions, and report that policies are not consistently implemented with all members of a clinic or institution. Some prescribers perceive an inherent contradiction between academic centers and national societies receiving money from pharmaceutical companies, and then recommending restriction at the level of the individual prescriber. Prescribers with different training backgrounds present a few novel reasons for these meetings.Conclusions: Despite evidence that PR detailing influences prescribing, providers from several health professions continue to believe that PR interactions improve patient care, and that they can adequately evaluate and filter information presented to them by PRs. Focus group comments suggest that cultural change is necessary to break the norms that exist in many settings. Applying policies consistently, considering non-physician members of the healthcare team, working with trainees, restructuring the current primary care model and offering convenient, individualized, non-biased educational options may aid success.

This journal watch is sponsored by the Alliance for Clinical Education (ACE). The purpose of this article is to summarize medical education manuscripts from specialty journals that are important and relevant to educators across specialties. Specialties included in our review were cardiology, gastroenterology, general internal medicine, pulmonology, nephrology, hematology and oncology, endocrinology, rheumatology, infectious disease, and neurology. We are grateful to Teaching and Learning in Medicine and ACE for giving us the opportunity to publish this review. The Clerkship Directors in Internal Medicine Research Committee conducted this review. Included are English articles published from September 2006 through September 2007. PubMed was searched for peer-reviewed research publications reporting primary data on medical education. Medical subject heading terms included combinations of medical education, medical student, residency training, practice, undergraduate medical education, graduate medical education, internship and residency, and continuing medical education. We also reviewed the bibliographies of all articles found though our PubMed search to identify additional articles that may not have been included in PubMed's search engine. Furthermore, we discussed identified articles with content experts in each specialty to ensure that appropriate journals and articles were included from each subspecialty. The journals that we selected for review are not often read by the typical medical educator. We included articles from general and subspecialty journals of internal medicine excluding the following, which have a focus on medical education or cross-specialties: Academic Medicine, Advances in Health Science Education, Medical Education, Medical Teacher, Teaching and Learning in Medicine, Journal of the American Medical Association, and New England Journal of Medicine. Specialties included in our review were cardiology, gastroenterology, general internal medicine, pulmonology, nephrology, hematology and oncology, endocrinology, rheumatology, infectious disease, and neurology. We also reviewed the bibliographies of all articles found though our PubMed search to identify additional articles. Furthermore, we discussed identified articles with content experts in each specialty to ensure that appropriate journals and articles were included from each subspecialty. Authors rated each article based on relevance, rigor, importance, and generalizibility of findings. We also sought to include articles from each phase in the continuum of medical education: undergraduate, graduate, and continuing medical education as well as qualitative and quantitative studies. Articles were ranked by each author. We then held conference calls and had e-mail discussions to establish consensus on the articles included in this review. The following is a summary of each selected article grouped by theme. [ABSTRACT FROM AUTHOR]

Background: Recent changes in healthcare system and training mandates have altered the clinical learning environment. We incorporated reflective writing into Internal Medicine clerkships (IMcs) in multiple institutions so students could consider the impact of clerkship experiences on their personal and professional development. We analyzed student reflections to inform curricula and support learning.Methods: We qualitatively analyzed the reflections of students at 3 US medical schools during IMcs (N = 292) to identify themes, tone, and reflective quality using an iterative approach. Chi-square tests assessed differences between these factors and across institutions.Findings: Students openly described powerful experiences. Major themes focused on 4 categories: personal issues (PI), professional development (PD), relational issues (RI), and medical care (MC). Each major theme was represented at each institution, although with significant variability between institutions in many of the subcategories including student role (PI), development-as-a-physician (PD), professionalism (PD) (p < 0.001). Students used positive tones to describe student role, development-as-a-physician and physician-patient relationship (PD) (p < 0.01-0.001), and negative tones for quality and safety (MC) (p < 0.05). Only 4% of writings coded as professionalism had a positive tone. Students employed a "reporting" voice in writing about clinical problem-solving, healthcare systems, and quality/safety (MC).Discussion: Reflection is considered important to professional development. Our analysis suggests that students at 3 institutions reflect on similar experiences. Theme variability across institutions implies curricula should be tailored to local culture. Reflective quality analysis suggests students are better equipped to reflect on certain experiences over others, which may impact learning. Student reflections can function as a mirror for our organizations, offer institutional feedback for support and improvement, and inform curricula for learners and faculty.

Uncontrolled hypertension is a significant health problem, due in part to patients' under-use of antihypertensive medications. This study explored what factors influence patients' decisions to accept or resist initiation of pharmacologic therapy for hypertension. A total of 210 subjects reviewed a clinical vignette and a hypothetical physician-patient dialogue. They then self-reported their likelihood of accepting the physician's recommendation to initiate therapy with an antihypertensive. Additional measures included trust in the physician, satisfaction, beliefs about medication effectiveness, safety and side-effects, and beliefs about hypertension. Analyses included bivariate correlations and multivariate linear regression. Findings suggest that the strongest correlates of intent to begin therapy were trust in the physician (r = 0.65, p< 0.01), satisfaction with communication (r= 0.53, p< 0.01), and belief that medications can effectively treat hypertension (r = 0.45, p< 0.01). Three other beliefs were also correlated with acceptance of treatment: the belief that physicians do not prescribe unsafe medications (r=0.25, p<0.01), worry about having hypertension (r = 0.18, p<0.01) and belief that hypertension is a very serious disease (r= 0.26, p<0.01). Acceptance of treatment was not correlated with worry about medication side-effects or belief that medications cause problems (p> 0.01). The tone of the dialogue (positive versus negative) did not result in statistically significant differences in subjects' responses on any measures. The study concludes that attention to patients' perceptions and beliefs about hypertension and medication efficacy may help patients accept pharmacologic treatment. [ABSTRACT FROM AUTHOR]

Background: The 4th-year internal medicine subinternship (subI), with its strong emphasis on experience-based learning and increased patient responsibilities, is an important component of undergraduate medical education. Discussions have begun amongst educational leaders on the importance of standardizing curriculum and evaluation tools utilized during the subinternship. Purpose: The objective of this survey was to describe the current state of educational practices regarding the subI curriculum, use of Clerkship Directors in Internal Medicine (CDIM) curricular guidelines, evaluation methodologies, and subintern call frequency and duty hours. Methods: The survey was a part of the CDIM annual survey sent to 109 institutional members in 2005. The subinternship survey included 17 questions that addressed the prevalence of formal curricula in the subinternship, use of CDIM curricular guidelines and resources, and the evaluation tools utilized for assessment of the subinternship. Two questions examined the call frequency and duty hours of the subinterns. Results: Eighty-eight members responded (81%). Of the respondents, 37% have a formal curriculum and 35% used CDIM curricular guidelines for the subinternship. More than half of the respondents agreed that the curricular guide helped organize their subI rotations (53%), and 48% agreed that it enhanced the quality of subI education. A global rating summative evaluation form (56%) was the most commonly used evaluation tool in the subinternship. Objective Structured Clinical Examinations1-3 (1%) and Mini-Clinical Evaluation Exercise (mini-CEX)4(2%) were much less utilized during the subinternship. The respondents expressed an interest in the development of a standardized exam (47%) and clinical assessment tools such as the mini-CEX (59%). The vast majority of IM subinterns participate in 3 to 9 calls per rotation and spend less than 80 hr in the hospital per week. Conclusions: A formal curriculum is offered in slightly more than one third of subIs. Clerkship directors expressed interest in developing standardized evaluation tools to assess subintern competencies. The majority of IM subinterns spend less than 80 hr in the hospital per week. Further studies are needed to assess barriers to incorporating a formal curriculum and develop standardized tools to assess subintern competencies. [ABSTRACT FROM AUTHOR]

- Abstract
Aims We assessed the utility of three self-assessment instruments: the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the post-operative Patient Global Impression of Improvement (PGI-I) score, and the International Prostate Symptom Score (IPSS) by correlating them with an objective outcome, the change in 24-hr pad weight, after a male perineal sling. Methods Twenty-six men with urodynamically confirmed stress incontinence underwent a male perineal sling. Patients were evaluated pre-operatively and post-operatively with a 24-hr pad test, IPSS and ICIQ-SF. Patients also completed the PGI-I post-operatively. Changes in study parameters were compared via the paired t-test, and correlations were performed using Spearman's rho. Results There were significant reductions in 24-hr pad weight (−274 g, P < 0.001), percentage 24-hr pad weight (54.2%), ICIQ-SF score (−6.3, P < 0.001), and the three ICIQ-SF subscores (−1.2, −1.7, −3.4 for Questions 3, 4, and 5, respectively, P < 0.001 for all). The change in total ICIQ-SF score and the post-operative PGI-I score correlated strongly with percentage reduction in 24-hr pad weight (r = −0.68, P < 0.001; r = −0.81, P < 0.001, respectively) and with each other (r = 0.79, P < 0.001). The change in all three ICIQ-SF subscores correlated significantly with percentage reduction in 24-hr pad weight and with post-operative PGI-I score. There was no significant change in the IPSS or the voiding or storage subscores, and none correlated with any other study parameter. Conclusions This study validates the construct validity of the ICIQ-SF and PGI-I in the assessment of treatment for male stress incontinence and should make clinicians confident in comparing studies of incontinence treatment utilizing the change ICIQ-SF score, the post-operative PGI-I score, and percentage reduction in 24-hr pad weight as outcome measures.

BACKGROUND: Disclosure of medical errors is encouraged, but research on how patients respond to specific practices is limited. OBJECTIVE: This study sought to determine whether full disclosure, an existing positive physician-patient relationship, an offer to waive associated costs, and the severity of the clinical outcome influenced patients' responses to medical errors. PARTICIPANTS: Four hundred and seven health plan members participated in a randomized experiment in which they viewed video depictions of medical error and disclosure. DESIGN: Subjects were randomly assigned to experimental condition. Conditions varied in type of medication error, level of disclosure, reference to a prior positive physician-patient relationship, an offer to waive costs, and clinical outcome. MEASURES: Self-reported likelihood of changing physicians and of seeking legal advice: satisfaction, trust, and emotional response. RESULTS: Nondisclosure increased the likelihood of changing physicians, and reduced satisfaction and trust in both error conditions. Nondisclosure increased the likelihood of seeking legal advice and was associated with a more negative emotional response In the missed allergy error condition, but did not have a statistically significant impact on seeking legal advice or emotional response in the monitoring error condition. Neither the existence of a positive relationship nor an offer to waive costs had a statistically significant impact. CONCLUSIONS: This study provides evidence that full disclosure is likely to have a positive effect or no effect on how patients respond to medical errors. The clinical outcome also influences patients' responses. The impact of an existing positive physician-patient relationship, or of waiving costs associated with the error remains uncertain.

CONTEXT: Trainees are exposed to medical errors throughout medical school and residency. Little is known about what facilitates and limits learning from these experiences. OBJ'ECT/VE: To identify major factors and areas of tension in trainees' learning from medical errors. DESIGN, SETTING, AND PARTICIPANTS: Structured telephone interviews with 59 trainees (medical students and residents) from 1 academic medical center. Five authors reviewed transcripts of audiotaped interviews using content analysis. RESULTS: Trainees were aware that medical errors occur from early in medical school. Many had an intense emotional response to the idea of committing errors in patient care. Students and residents noted variation and conflict in institutional recommendations and individual actions. Many expressed role confusion regarding whether and how to initiate discussion after errors occurred. Some noted the conflict between reporting errors to seniors who were responsible for their evaluation. Learners requested more open discussion of actual errors and faculty disclosure. No students or residents felt that they learned better from near misses than from actual errors, and many believed that they learned the most when harm was caused. CONCLUSIONS: Trainees are aware of medical errors, but remaining tensions may limit learning, institutions can immediately address variability in faculty response and local culture by disseminating clear, accessible algorithms to guide behavior when errors occur. Educators should develop longitudinal curricula that integrate actual cases and faculty disclosure. Future multi-institutional work should focus on identified themes such as teaching and learning in emotionally charged situations, learning from errors and near misses and balance between individual and systems responsibility.

Purpose To assess primary care preceptors' perceptions of the issues involved in teaching when medical errors occur. In particular, we examined preceptors' responses to trainees involved in medical errors, factors influencing their response, and their perceptions of barriers to teaching from medical errors. Methods A total of 38 primary care preceptors participated in 7 focus groups on teaching and medical errors. Participants were drawn from medical schools throughout the northeastern USA. Content analysis of transcripts identified major themes. Results We developed a framework describing how preceptors and learners respond to medical errors, the factors that influence these responses, and the relationships between these. We also identified barriers to teaching from medical errors. Preceptors are especially sensitive to learners' distress as a result of errors. Emotional distress and self-doubt are seen as inimical to learning, possibly causing more attention to be directed to emotional support than to correction and instruction. At the same time, accepting responsibility for errors was seen as prerequisite to learning. For many preceptors, vivid recollections of their own errors during training were influential in determining how they in turn responded as preceptors; none reported having received training in this area. Conclusion This study describes preceptors' experiences of responding to trainees' medical errors, and identifies barriers to teaching from errors. The intersection of patient safety and medical education is a critical area for future research. We propose a framework that may help guide future research efforts, which should focus on identifying factors that promote faculty development to optimise learning and reduce the likelihood of future errors.

Context: Morbidity and mortality conferences in residency programs are intended to discuss adverse events and errors with a goal to improve patient care. Little is known about whether residency training programs are accomplishing this goal. Objective: To determine the frequency at which morbidity and mortality conference case presentations include adverse events and errors and whether the errors are discussed and attributed to a particular cause. Design, Setting, and Participants: Prospective survey conducted by trained physician observers from July 2000 through April 2001 on 332 morbidity and mortality conference case presentations and discussions in internal medicine (n = 100) and surgery (n = 232) at 4 US academic hospitals. Main Outcome Measures: Frequencies of presentation of adverse events and errors, discussion of errors, and attribution of errors. Results: In internal medicine morbidity and mortality conferences, case presentations and discussions were 3 times longer than in surgery conferences (34.1 minutes vs 11.7 minutes; P = .001), more time was spent listening to invited speakers (43.1% vs 0%; P<.001), and less time was spent in audience discussion (15.2% vs 36.6%; P<.001). Fewer internal medicine case presentations included adverse events (37 [37%] vs 166 surgery case presentations [72%]; P<.001) or errors causing an adverse event (18 [18%] vs 98 [42%], respectively; P = .001). When an error caused an adverse event, the error was discussed as an error less often in internal medicine (10 errors [48%] vs 85 errors in surgery [77%]; P = .02). Errors were attributed to a particular cause less often in medicine than in surgery conferences (8 [38%] of 21 medicine errors vs 88 [79%] of 112 surgery errors; P<.001). In discussions of cases with errors, conference leaders in both internal medicine and surgery infrequently used explicit language to signal that an error was being discussed and infrequently acknowledged having made an error. Conclusions: Our findings call into question whether adverse events and errors are routinely discussed in internal medicine training programs. Although adverse events and errors were discussed frequently in surgery cases, teachers in both surgery and internal medicine missed opportunities to model recognition of error and to use explicit language in error discussion by acknowledging their personal experiences with error.

Human telomerase reverse transcriptase (hTERT) is the catalytic component of a functional telomerase complex, which is important in maintaining cell immortality. In most normal human adult cells, the expression of telomerase is very low and/or transient. In contrast, almost 90% of human tumors express a relatively high level of telomerase implying the possibility of using hTERT as a universal candidate tumor antigen. In this study, we show that human monocyte-derived dendritic cells (DCs) lack telomerase activity. Similar to other normal somatic cells, DCs express the RNA (hTR) component but not the catalytic component, hTERT. We also show that telomerase activity could be reconstituted using either lipid-mediated transfection of the hTERT plasmid DNA or transduction with an E1-, E3-deleted adenoviral vector containing the hTERT gene. However, relative to plasmid transfection, adenoviral gene transfer produced higher levels of hTERT expression. Nine of 10 Adh TERT-transduced DCs were able to generate CTL responses, while only three of nine plasmid-transfected DCs did. CTLs primed against hTERT exhibited killing of telomerase positive but not telomerase negative tumor lines of diverse tissue origins. Antigenic specificity of these T cells to telomerase was further determined by introducing hTERT gene into a telomerase negative cell line, U2OS, by adenoviral transduction. Although some antigenic specificity was directed against adenoviral epitopes, the majority of CTLs were targeted against telomerase-derived antigen(s). Thus, the hTERT gene, particularly as delivered via the recombinant adenovirus, may be useful as vaccine to induce specific T-cell-mediated tumor immunity in cancer patients. In addition, our results suggest that telomerase activity and/or telomerase expression after hTERT gene transfer have a predictive value in the success of hTERT/DC-based cancer vaccination.

COE, CHRISTOPHER L, BOSENBERG, LEON T, FISCHER, MELISSA, and LEVINE, SEYMOUR Psychological Factors Capable of Preventing the inhibition of Antibody Responses in Separated Infant Monkeys CHILD DEVELOPMENT, 1987, 58, 1420-1430 The capacity of infant squirrel monkeys to mount an antibody response to viral challenge was evaluated after removal from their mothers m several social and physical environments Control and separated infants were rejected with a benign virus, the bacteriophage X174, and levels of neutralizing antibody were assessed for 3 weeks Infants separated alone m an unfamiliar environment showed a significant reduction m antibody levels as compared to control infants Allowing infants to remain in the home environment, either alone or with peers, prevented this inhibition of antibody responses from occurring Similarly, providing familiar peers in the novel environment facilitated the normal expression of antibody responses These results indicate that the trauma of maternal separation is significantly reduced when infants are familiar with the separation environment or familiar social companions are available The reduced antibody response was associated with the highest level of adrenal activation induced by the unfamiliar separation condition, but antibody titers and plasma cortisol levels could not be specifically correlated in individual infants.

Penile strangulation is an infrequent clinical condition that has widely been reported. It usually results following placement of a constriction device to enhance sexual stimulation. Early treatment is essential to avoid potential complications, including ischemic necrosis and autoamputation. We describe the use of a Large Orthopedic Pin Cutter to remove a metal penile constriction device in the Emergency Department (ED). This case report describes the relatively safe technique of using an instrument available in many hospitals that can be added to the physician's arsenal in the removal of metal constriction devices.
