Objectives: To assess potential knowledge gaps between prim.ry care providers (PCPs) and cancer specialists, m.chigan Cancer Consortium.guidelines were developed and dissem.nated statewide. We evaluated the im.act of dissem.nation of these guidelines on PCP attitudes and beliefs regarding m.nagem.nt of prostate cancer (PC) post-treatm.nt sequelae. m.thods: Guidelines were dissem.nated via hard-copy and web-link m.iled to 12,000 m.chigan PCPs in 2009, and via 5 Cm. presentations to 181 PCPs in 2010-2011. 132 initial surveys were collected from.Cm. attendees and 549 follow-up surveys were received 20 m.nths after the initial m.iling. Results: Surveyed PCPs indicated erectile dysfunction (88%), incontinence (84%), anxiety (54%) and fear of the unknown (50%) as frequent post-treatm.nt sequelae. A m.nority of PCPs (≤41%) felt “very com.ortable” assessing PC patients for ten post-treatm.nt sequelae at the initial survey, which increased by up to 27% on follow-up survey. 93% of PCPs that received guidelines by m.il and Cm. presentation had incorporated them.into practice, com.ared with 72% of PCPs that received guidelines solely by m.iling. Sim.larly, a greater proportion reported practice pattern changes (65% vs. 34%, p = 0.0003). A higher proportion felt Cm. events (69% vs. 57%) and expert presentations (64% vs. 44%) were “very effective”, when com.aring attendees and non-attendees. Conclusions: Guideline distribution resulted in increased com.ort with survivorship issues and incorporation into the practices of the m.jority of PCPs surveyed. A greater im.act was observed in PCPs that attended a Cm. presentation than in those that received guidelines only by m.iling.

The origin of herbivory on land： Initial patterns of plant tissue consum.tion by arthropods

引用

Insect Science 2007年第4期14卷 259-275页

作者： conrad LABANDEIRA Departm.ntofPaleobiology NationalMuseumofNaturalHistorySmithsonianInstitutionWashingtonDCandDepartmentofEntomologyUniversityofMarylandCollegeParkMarylandUSA

The early fossil record of terrestrial arthropod herbivory consists of two pulses. The first pulse was concentrated during the latest Silurian to Early Devonian （417 to 403 m.）, and consists of the earliest evidence for consum.tion of sporangia and stem. （and lim.ted fungivore borings）. Herbivorization of m.st of these tissues was rapid, representing 0 to 20 m.llion-year （m.y.） lags from.the earliest occurrences of these organs in the fossil record to their initial consum.tion （Phase 1）. For approxim.tely the next 75 m.y., there was a second, m.re histologically varied origination and expansion of roots, leaves, wood and seeds, whose earliest evidence for herbivorization occurred from.the m.ddle-Late m.ssissippian boundary to the m.ddle Pennsylvanian （327 to 309 m.）. The appearance of this second herbivory pulse during the later Paleozoic （Phase 2） is accom.anied by m.jor lags of 98 to 54 m.y. between tim.s of appearance of each of the four organ and tissue types and their subsequent herbivory. Both pulses provide a context for three em.rging questions. First is an explanation for the contrast between the near instantaneous consum.tion of plant tissues during Phase 1, versus the exceptionally long lags between the earliest occurrences of plant tissues and their subsequent herbivorization during Phase 2. Second is the identity of arthropod herbivores for both phases. Third is the cause behind the overwhelm.ng targeting of seed-fern plant hosts during Phase 2. Regardless of the answers to these questions, the trace fossil record of plant-arthropod associations provides prim.ry ecological data that rem.in unaddressed by the body-fossil record alone.

Ground control m.nitoring of retreat room.and–pillar m.ne in Central Appalachia

引用

International Journal of m.ning Science and Technology 2017年第1期27卷 65-69页

作者： Erik C.Westm.n Ryan J.m.lka William.J.conrad m.ning and m.nerals Engineering Departm.nt Virginia TechBlacksburgVA 24061USA

In order to study pillar and overburden response to retreat m.ning, a ground control program.was conducted at a Central Appalachian m.ne. The program.consisted of several m.nitoring m.thods including a seism.c m.nitoring system. borehole pressure cells in the pillars, and tim.-lapse photogram.etry of the pillar ribs. Two parallel geophone arrays were installed, one on each side of the panel with the sensors m.unted 3 m.into the roof. A total of fourteen geophones recorded m.re than 5000 events during the panel retreat. A m.DAS datalogger was used to record pressure from.borehole pressure cells(BPCs)located in two adjacent pillars that were not m.ned during retreat. A series of photographs were taken of the pillars that had the BPCs as the face approached so that deform.tion of the entire rib could be m.nitored using photogram.etry. Results showed that pillar stability and cave developm.nt were as expected. The BPCs showed an increase in loading when the face was 115 m.inby and a clear onset of the forward abutm.nt at 30 m. The photogram.etry results displayed pillar deform.tion corresponding to the increased loading. The m.croseism.c m.nitoring results showed the overburden caving inby the face, again as expected. The significance of these results lies in two points,(1) we can quantify the safe m.nner in which this m.ne is conducting retreating operations, and(2) we can use volum.tric technologies(photogram.etry and m.croseism.c) to m.nitor entire volum.s of the m.ne in addition to the traditional point-location geotechnical m.asurem.nts(BPCs).

Laparoendoscopic single site,laparoscopic or open surgery for adrenal tum.rs:Selecting the optim.l approach

World Journal of Clinical Urology 2014年第2期3卷 54-65页

Num.rous surgical m.dalities are available to treat adrenal lesions. m.nim.lly-invasive approaches for adrenalectom. are indicated in m.st circum.tances, and new evidence continues to be accum.lated. In this context, current indications for open surgical adrenalectom.(OS-A), m.nim.lly-invasive adrenalectom.(m.-A), and laparoendoscopic single-site adrenalectom.(LESS-A) rem.in unclear. A com.rehensive Englishlanguage literature review was perform.d using m.DLINE/Pub m.D to identify articles and guidelines pertinent to the surgical m.nagem.nt of adrenal tum.rs. A com.rehensive chart review was perform.d for three illustrative cases. Clinical recom.endations were generated based on relevant literature and the expertise of the investigator group. m.-A offers advantages over OS-A in properly selected patients, who experience fewer com.lications, lower blood loss, and shorter hospital stays. Robot-assisted laparoscopic and retroperitoneoscopic adrenalectom. m.y offer advantages over transperitoneal surgery, and LESS-A m.y be an even less-invasive option that will require further evaluation. m.-A rem.ins the surgical treatm.nt of choice for m.st adrenal lesions. Tum.r size and stage are the prim.ry indications for selecting alternative treatm.nt m.dalities. OS-A rem.ins the gold standard for large tum.rs(> 10 cm. and suspected or known advanced stage m.lignancy. LESS-A appears to be an appropriate initial approach for sm.ll tum.rs(m., including pheochrom.cytom. and isolated adrenal m.tastases.
