Experiences of Female and Male Medical Students With Death, Dying, and Palliative Care: One Size Does Not Fit All

Background: Medical students learn about death, dying, and palliative care (DDPC) through formal curricular offerings and informal clinical experiences; however, the lessons learned in the clinic may be at odds with the formal curriculum. Reflective writing is a means for students to “bracket” their DDPC experiences and reconcile conflicts between the formal and informal curriculum. Objectives: The aim of this study is to compare the level of reflection demonstrated in medical students’ narratives on DDPC with other experiences and to examine the domains of professionalism that students perceive to be prevalent in their DDPC experiences. Methods: Third-year medical students submitted professionalism narratives during their internal medicine clerkship. We identified a subset of narratives related to DDPC (n = 388) and randomly selected control narratives (n = 153). We assessed the level of reflection demonstrated in the narratives using a validated rubric and analyzed the professionalism domains that students identified as relevant to their experience. Results: There was no difference in reflective level between DDPC and control narratives. Within the DDPC group, female students demonstrated higher reflection (2.24 ± 0.71) than male students (2.01 ± 0.77; P < .001). Caring, compassion and communication, and honor and integrity were prominent among DDPC narratives. More females identified caring, compassion, and communication as relevant to their DDPC experiences, whereas more males identified altruism. Conclusion: Males and females have different perceptions of DDPC experiences, and female students appear to be more deeply impacted. These findings can help clinical faculty engage students more effectively with this challenging topic

Teaching Self-Management Skills in Persons with Chronic Lower Limb Swelling and Limited Mobility: Evidence for Usability of Telerehabilitation

The purpose of this study was to evaluate the usability of telerehabilitation as a method of teaching self-management for chronic swelling of the lower limbs in persons with limited mobility. An in-home telerehabilitation self-management education protocol for chronic swelling of the lower limbs, termed Telerehabilitation to Empower You to Manage and Prevent Swelling (TR-PUMPS), was implemented using the Versatile and Integrated System for Telerehabilitation (VISYTER) software platform. Participants (n=11) were 36-79 years old, predominately female (72.7%) and diagnosed with a variety of health conditions. Participants’ perceived usability scores of the remote delivery of TR-PUMPS was high with a median score of 6.67 (range 4.90 - 7.00) on a Likert scale: 1= disagree to 7= agree. There was no correlation between participants’ familiarity with information technology and their perception of telerehabilitation usability. These results support telerehabilitation as a viable method for teaching a home-based, self-managemen

Young adult outcomes associated with teen pregnancy among high-risk girls in a randomized controlled trial of Multidimensional Treatment Foster Care

Teen pregnancy is associated with a host of deleterious outcomes for girls, such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, including adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group care (GC) in a study of adolescent girls (significantly fewer pregnancies reported in the 2-year follow-up for MTFC girls), the present study followed this sample into young adulthood (approximately 7 years post-baseline) to examine the effects of adolescent pregnancy on young adult substance use and pregnancy-related outcomes. All participants were randomly assigned to MTFC (N = 81) or GC (N = 85) as adolescents as part of a randomized controlled trial (RCT). Results from logistic regression analyses indicated that becoming pregnant during the 2-year follow-up was significantly related to illicit drug use, miscarriage from a new pregnancy, and child welfare involvement 7 years post-baseline. In addition, baseline marijuana use predicted marijuana use at 7 years post-baseline. © 2013 Copyright Taylor and Francis Group, LLC

Impact of a disease-management program on symptom burden and health-related quality of life in patients with idiopathic pulmonary fibrosis and their care partners

Patients were recruited from the Dorothy P. and Richard P. Simmons Center for Interstitial Lung Disease, located within the University of Pittsburgh Medical Center. Idiopathic pulmonary fibrosis results in scarring of the lung and respiratory failure, and has a median survival of 3 to 5 years from the time of diagnosis. The purpose of this study was to determine whether patients with idiopathic pulmonary fibrosis and their care partners could be more optimally managed by a disease-management intervention entitled “Program to Reduce Idiopathic Pulmonary Fibrosis Symptoms and Improve Management,” which nurses delivered using the format of a support group. We hypothesized that participation would improve perceptions of health-related quality of life (HRQoL) and decrease symptom burden

Cryopyrin-Associated Periodic Syndrome: An Update on Diagnosis and Treatment Response

Cryopyrin-associated periodic syndrome (CAPS) is a rare hereditary inflammatory disorder encompassing a continuum of three phenotypes: familial cold autoinflammatory syndrome, Muckle-Wells syndrome, and neonatal-onset multisystem inflammatory disease. Distinguishing features include cutaneous, neurological, ophthalmologic, and rheumatologic manifestations. CAPS results from a gain-of-function mutation of the NLRP3 gene coding for cryopyrin, which forms intracellular protein complexes known as inflammasomes. Defects of the inflammasomes lead to overproduction of interleukin-1, resulting in inflammatory symptoms seen in CAPS. Diagnosis is often delayed and requires a thorough review of clinical symptoms. Remarkable advances in our understanding of the genetics and the molecular pathway that is responsible for the clinical phenotype of CAPS has led to the development of effective treatments. It also has become clear that the NLRP3 inflammasome plays a critical role in innate immune defense and therefore has wider implications for other inflammatory disease states

Anosmin-1 contributes to brain tumor malignancy through integrin signal pathways

Anosmin-1, encoded by the KAL1 gene, is an extracellular matrix (ECM)-associated protein which plays essential roles in the establishment of olfactory and GNRH neurons during early brain development. Loss-of-function mutations of KAL1 results in Kallmann syndrome with delayed puberty and anosmia. There is, however, little comprehension of its role in the developed brain. As reactivation of developmental signal pathways often takes part in tumorigenesis, we investigated if anosmin-1-mediated cellular mechanisms associated with brain tumors. Our meta-analysis of gene expression profiles of patients' samples and public microarray datasets indicated that KAL1 mRNA was significantly upregulated in high-grade primary brain tumors compared with the normal brain and low-grade tumors. The tumor-promoting capacity of anosmin-1 was demonstrated in the glioblastoma cell lines, where anosmin-1 enhanced cell motility and proliferation. Notably, anosmin-1 formed a part of active β1 integrin complex, inducing downstream signaling pathways. ShRNA-mediated knockdown of anosmin-1 attenuated motility and growth of tumor cells and induced apoptosis. Anosmin-1 may also enhance the invasion of tumor cells within the ECM by modulating cell adhesion and activating extracellular proteases. In a mouse xenograft model, anosmin-1-expressing tumors grew faster, indicating the role of anosmin-1 in tumor microenvironment in vivo. Combined, these data suggest that anosmin-1 can facilitate tumor cell proliferation, migration, invasion, and survival. Therefore, although the normal function of anosmin-1 is required in the proper development of GNRH neurons, overexpression of anosmin-1 in the developed brain may be an underlying mechanism for some brain tumors

Predictors of linkage to care following community-based HIV counseling and testing in rural Kenya

Despite innovations in HIV counseling and testing (HCT), important gaps remain in understanding linkage to care. We followed a cohort diagnosed with HIV through a community-based HCT campaign that trained persons living with HIV/AIDS (PLHA) as navigators. Individual, interpersonal, and institutional predictors of linkage were assessed using survival analysis of self-reported time to enrollment. Of 483 persons consenting to follow-up, 305 (63.2%) enrolled in HIV care within 3 months. Proportions linking to care were similar across sexes, barring a sub-sample of men aged 18–25 years who were highly unlikely to enroll. Men were more likely to enroll if they had disclosed to their spouse, and women if they had disclosed to family. Women who anticipated violence or relationship breakup were less likely to link to care. Enrolment rates were significantly higher among participants receiving a PLHA visit, suggesting that a navigator approach may improve linkage from community-based HCT campaigns.Vestergaard Frandse

HIV-1 Populations in Semen Arise through Multiple Mechanisms

HIV-1 is present in anatomical compartments and bodily fluids. Most transmissions occur through sexual acts, making virus in semen the proximal source in male donors. We find three distinct relationships in comparing viral RNA populations between blood and semen in men with chronic HIV-1 infection, and we propose that the viral populations in semen arise by multiple mechanisms including: direct import of virus, oligoclonal amplification within the seminal tract, or compartmentalization. In addition, we find significant enrichment of six out of nineteen cytokines and chemokines in semen of both HIV-infected and uninfected men, and another seven further enriched in infected individuals. The enrichment of cytokines involved in innate immunity in the seminal tract, complemented with chemokines in infected men, creates an environment conducive to T cell activation and viral replication. These studies define different relationships between virus in blood and semen that can significantly alter the composition of the viral population at the source that is most proximal to the transmitted virus

Neoproterozoic to early Paleozoic extensional and compressional history of East Laurentian margin sequences: The Moine Supergroup, Scottish Caledonides

Neoproterozoic siliciclastic-dominated sequences are widespread along the eastern margin of Laurentia and are related to rifting associated with the breakout of Laurentia from the supercontinent Rodinia. Detrital zircons from the Moine Supergroup, NW Scotland, yield Archean to early Neoproterozoic U-Pb ages, consistent with derivation from the Grenville-Sveconorwegian orogen and environs and accumulation post–1000 Ma. U-Pb zircon ages for felsic and associated mafic intrusions confirm a widespread pulse of extension-related magmatism at around 870 Ma. Pegmatites yielding U-Pb zircon ages between 830 Ma and 745 Ma constrain a series of deformation and metamorphic pulses related to Knoydartian orogenesis of the host Moinerocks. Additional U-Pb zircon and monazite data, and 40Ar/39Ar ages for pegmatites and host gneisses indicate high-grade metamorphic events at ca. 458–446 Ma and ca. 426 Maduring the Caledonian orogenic cycle.The presence of early Neoproterozoic silici clastic sedimentation and deformation in the Moine and equivalent successions around the North Atlantic and their absence along strike in eastern North America reflect contrasting Laurentian paleogeography during the breakup of Rodinia. The North Atlantic realm occupied an external location on the margin of Laurentia, and this region acted as a locus for accumulation of detritus (Moine Supergroup and equivalents) derived from the Grenville-Sveconorwegian orogenic welt, which developed as a consequence of collisional assembly of Rodinia. Neoproterozoic orogenic activity corresponds with theinferred development of convergent platemargin activity along the periphery of the supercontinent. In contrast in eastern North America, which lay within the internal parts of Rodinia, sedimentation did not commence until the mid-Neoproterozoic (ca. 760 Ma) during initial stages of supercontinent fragmentation. In the North Atlantic region, this time frame corresponds to a second pulse of extension represented by units such as the Dalradian Supergroup, which unconformably overlies the predeformed Moine succession

Efficient Nuclear Transport of Structurally Disturbed Cargo: Mutations in a Cargo Protein Switch Its Cognate Karyopherin

The Karyopherin (Kap) family of nuclear transport receptors enables trafficking of proteins to and from the nucleus in a precise, regulated manner. Individual members function in overlapping pathways, while simultaneously being very specific for their main cargoes. The details of this apparent contradiction and rules governing pathway preference remain to be further elucidated. S. cerevisiae Lhp1 is an abundant protein that functions as an RNA chaperone in a variety of biologically important processes. It localizes almost exclusively to the nucleus and is imported by Kap108. We show that mutation of 3 of the 275 residues in Lhp1 alters its import pathway to a Kap121-dependent process. This mutant does not retain wild-type function and is bound by several chaperones. We propose that Kap121 also acts as a chaperone, one that can act as a genetic buffer by transporting mutated proteins to the nucleus
