    1%). Flattening of the retina and closure of all retinal breaks was achieved in all eyes after a single surgery. Late recurrence of retinal detachment occurred in two eyes (3.9%) due to proliferative vitreoretinopathy (PVR). No complicated cataract or iatrogenic retinal breaks were detected in all eyes.

    DFCE technique could be effectively used for treatment of uncomplicated superior bullous RRD in adults ⩽40 years. It is safe and provides good visualization during surgery with no iatrogenic retinal breaks or complicated cataract.

Ever changing conditions call for the development of theory and simulation tools to finely describe multiple strata of society while supporting the evaluation of “what-if” scenarios. Particularly important is to assess the effectiveness of potential testing approaches and vaccination strategies. Here, an agent-based modeling platform is proposed to simulate the spreading of COVID-19 in small towns and cities, with a single-individual resolution. The platform is validated on real data from New Rochelle, NY-one of the first outbreaks registered in the United States. Supported by expert knowledge and informed by reported data, the model incorporates detailed elements of the spreading within a statistically realistic population. Along with pertinent functionality such as testing, treatment, and vaccination options, the model accounts for the burden of other illnesses with symptoms similar to COVID-19. Unique to the model is the possibility to explore different testing approaches-in hospitals or drive-through facilities-and vaccination strategies that could prioritize vulnerable groups. Decision-making by public authorities could benefit from the model, for its fine-grain resolution, open-source nature, and wide range of features.Purpose GI-4000, a series of recombinant yeast expressing four different mutated RAS proteins, was evaluated in subjects with resected ras-mutated pancreas cancer. Methods Subjects (n = 176) received GI-4000 or placebo plus gemcitabine. Subjects’ tumors were genotyped to identify which matched GI-4000 product to administer. Immune responses were measured by interferon-γ (IFNγ) ELISpot assay and by regulatory T cell (Treg) frequencies on treatment. Pretreatment plasma was retrospectively analyzed by matrix-assisted laser desorption/ionization-time-of-flight (MALDI-ToF) mass spectrometry for proteomic signatures predictive of GI-4000 responsiveness. Results GI-4000 was well tolerated, with comparable safety findings between treatment groups. The GI-4000 group showed a similar pattern of median recurrence-free and overall survival (OS) compared with placebo. For the prospectively defined and stratified R1 resection subgroup, there was a trend in 1 year OS (72% vs. 56%), an improvement in OS (523.5 vs. 443.5 days [hazard ratio (HR) = 1.06 [confidence interval (CI) 0.53-2.13], p = 0.872), and increased frequency of immune responders (40% vs. 8%; p = 0.062) for GI-4000 versus placebo and a 159-day improvement in OS for R1 GI-4000 immune responders versus placebo (p = 0.810). For R0 resection subjects, no increases in IFNγ responses in GI-4000-treated subjects were observed. A higher frequency of R0/R1 subjects with a reduction in Tregs (CD4+/CD45RA+/Foxp3low) was observed in GI-4000-treated subjects versus placebo (p = 0.033). A proteomic signature was identified that predicted response to GI-4000/gemcitabine regardless of resection status. Conclusion These results justify continued investigation of GI-4000 in studies stratified for likely responders or in combination with immune check-point inhibitors or other immunomodulators, which may provide optimal reactivation of antitumor immunity.

    To establish the extent to which sound amplitudes delivered by a vibrating tuning fork change around its long axis and to evaluate whether such differences in amplitude might change the results of the Rinne test.

    Experimental measurements.

    Laboratory setting.

    Setup I a vibrating tuning fork was handheld and manually rotated around its long axis next to a sound recording device (the simulated ear) in order to record sound amplitude data at a full range of angles relative to the device; files were split into segments in which sound amplitude changed A (from a maximum to a minimum) and B (from a minimum to a maximum). Setup II a vibrating tuning fork was machine-rotated, and the angle of rotation, along with the sound amplitude, was automatically recorded through a single full rotation.

    The angles of 0° and 180° (which equate to the established best practice in Rinne testing) were associated with the highest sound amplitudes. All other angles decreased sound amplitude. The greatest decrease in amplitude was recorded at 51° and 130°. This difference ranged from 9.8 to 34.7 dB, depending on the initial amplitude.

    The outcome of a Rinne test can be affected if attention is not paid to the precise angle at which the tuning fork is held relative to the ear. The potential of this effect will be greater when high background noise or patient hearing loss requires that the tuning fork be vigorously excited to obtain high sound amplitudes.

    The recent outbreak of the COVID-19 altered the traditional paradigm of clinical medical education. While individual clerkships have shared their curricular adaptations via social and academic networking media, there is currently no organizational standard in establishing a non-clinical, Emergency Medicine (EM) virtual rotation (VR). The primary objective of this study was to describe EM clerkship directors’ (CDs) perspectives on their experience adapting an EM VR curriculum during the onset of the COVID-19 pandemic.

    A 21-item survey with quantitative and qualitative questions was disseminated between June and August 2020 to EM CDs via the Clerkship Director of Emergency Medicine (CDEM) Listserv to describe their experience and perspectives in adapting a VR during the spring of 2020.

    We analyzed 59 out of 77 EM clerkship survey responses. Among respondents, 52% adapted a VR while 47.5% did not. Of those who adapted a VR, 71% of CDs had 2 weeks or less to develop the new curriculum, with 84% reporting uslearning with limited time, this was not equivalent to the formal development of pre-planned VR experiences. Future faculty development and curriculum innovation are required to fully transition an in-person immersive experience to a non-inferior virtual experience.The COVID-19 pandemic has dramatically affected medical education. Emergency medicine (EM) requires excellence in multiple core competencies, including leadership, teamwork and communication skills, as well as procedural experience. To meet these objectives, we developed a hybrid simulation model that accommodated a reduced number of learners in our simulation center to allow for physical distancing, seamlessly integrated with an on-line integrated experience for remote learners. All learners participated or watched one adult and one pediatric simulation case. Fourteen residents participated in live simulation, while six residents and six medical students comprised the remote group. At the end of each case, the live-feed was ended, and separate debriefings were conducted by different EM faculty, in-person and on-line (via Zoom). An electronic survey was then sent to participants to rate the effectiveness of the intervention; 23 survey responses were collected 52.2% (12) from the live session and 47.2% (11) from the virtual session. Survey results demonstrated that the on-line simulation observation and debriefing had the same, if not better, satisfaction than in-person simulation sessions and debriefings. Due to its success, this new method of hybrid simulation will be our plan for the foreseeable future, at least until COVID-19 abates.

    The COVID-19 pandemic posed significant challenges to traditional simulation education. Because simulation is considered best practice for competency-based education, emergency medicine (EM) residencies adapted and innovated to accommodate to the new pandemic normal. Our objectives were to identify the impact of the pandemic on EM residency simulation training, to identify unique simulation adaptations and innovations implemented during the pandemic, and to analyze successes and failures through existing educational frameworks to offer guidance on the use of simulation in the COVID-19 era.

    The Society for Academic Emergency Medicine (SAEM)’s Simulation Academy formed the SimCOVID task force to examine the impact of COVID-19 on simulation didactics. A mixed-methods approach was employed. A literature search was conducted on the subject and used to develop an exploratory survey that was distributed on the Simulation Academy Listserv. The results were subjected to thematic analysis and examined through existnd organizational capacity to support simulation-based efforts for the evolving clinical and educational landscape.

    Offset analgesia (OA), a large reduction in pain after a brief increase in intensity of an otherwise stable painful stimulus, has been established by a large body of research. But the opposite effect, onset hyperalgesia (OH), a disproportional hyperalgesic response after a briefly decreased intensity of a painful stimulus, has only been investigated in one previous study.

    The aim of this study was to induce OA and OH in healthy participants and explore the effects of different stimulus ranges (increase/decrease of temperature) on OA and OH.

    A total of 62 participants were tested in 2 identical experiments. learn more Offset analgesia and OH conditions included 2 different temperature deviations (±1°C/±2°C) from initial temperature and were compared with a constant temperature (control).

    Offset analgesia was successfully elicited in OA

    in experiment 1, and in OA

    and OA

    in experiment 2. Results indicate a continuous stimulus-response relationship between the stimulus range and the resulting hypoalgesic respoe to following changes in temperature.The COVID-19 pandemic has affected daily lives of people around the world. People have already started to live wearing masks, keeping a safe distance from others and maintaining a high level of hygiene. This paper deals with an in-depth analysis of riskness associated with COVID-19 infections in Kolkata Municipal Corporation (KMC) at the sub-city (ward) level. Attempts have been made to identify the areas with high or low risk of infections using GIS-based geostatistical approach. Cosine Similarity Index has been used to rank different wards of KMC according to the degree of riskness. Four indices were computed to address intervention objectives and to determine ‘Optimized Prevention Rank’ of wards for future policy decisions. The highest risk areas were located in the eastern and western part of the city, to a great extent overlapped with wards containing larger share of population living in slums and/or below poverty level. While, highly infected areas lie in central Kolkata and in several wards at the eastern and northeastern periphery of the KMC.
