RESUMEN
BACKGROUND: Perforator dissection and flap elevation are routinely performed for microsurgical reconstruction; however, there is a steep learning curve to mastering these technical skills. Though live porcine models have been utilized as a microsurgical training model, there are significant drawbacks that limit their use, including cost, limited ability for repetition, and obstacles associated with animal care. Here we describe the creation of a novel perforator dissection model using latex augmented non-living porcine abdominal walls. We provide anatomic measurements that demonstrate valuable similarities and differences to human anatomy to maximize microsurgical trainee practice. METHODS: Six latex-infused porcine abdomens were dissected based on the deep cranial epigastric artery (DCEA). Dissection was centered over the abdominal wall mid-segment between the second and fourth nipple line. Dissection steps included exposure of lateral and medial row perforators, incision of anterior rectus sheath with perforator dissection, and dissection of DCEA pedicle. DCEA pedicle and perforator measurements were compared with deep inferior epigastric artery (DIEA) data in the literature. RESULTS: An average of seven perforators were consistently identified within each flap. Assembly of the model was performed quickly and allowed for two training sessions per specimen. Porcine abdominal walls demonstrate similar DCEA pedicle (2.6 ± 0.21 mm) and perforator (1.0 ± 0.18 mm) size compared with a human's DIEA (2.7 ± 0.27 mm, 1.1 ± 0.85 mm). CONCLUSION: The latex-infused porcine abdominal model is a novel, realistic simulation for perforator dissection practice for microsurgical trainees. Impact on resident comfort and confidence within a microsurgical training course is forthcoming.

BACKGROUND: Perforator dissection and flap elevation are routinely performed for microsurgical reconstruction; however, there is a steep learning curve to mastering these technical skills. Though live porcine models have been utilized as microsurgical training models, significant drawbacks limit their use. We recently developed a latex-perfused, nonliving, porcine abdomen perforator dissection simulation and described its anatomic similarity to the human deep inferior epigastric artery flap. The purpose was to assess the change in resident confidence in performing key operative steps of flap elevation and perforator dissection and obtain feedback on model realism and utility. METHODS: Seventeen plastic and reconstructive surgery resident physicians (postgraduate years 1-6) at a single institution participated in a perforator dissection session utilizing the simulation model. Each resident completed pre- and postactivity surveys to assess interval change in confidence in operating. The postactivity survey also asked residents to answer questions regarding their perception of the model's anatomic and surgical realism and utility in microsurgical training. RESULTS: Following a practice session using the latex-perfused, nonliving porcine abdomen, resident confidence was significantly increased in performing all key operative steps and the procedure overall (p = 0.001). All residents (n = 17, 100%) believed the model would improve "trainees' ability to perform perforator dissection in the operating room." Perforator, fascial, and pedicle anatomy were reported to be "Very" similar to human anatomy, with a median Likert score (MLS) of 4. Additionally, six out of the eight surgical steps were noted to be "Very" realistic, with only "Flap Design" and "Fascial Closure" found to be "Moderately" realistic with an MLS of 3. CONCLUSION: The latex-infused porcine abdominal model is a novel, realistic simulation for microsurgical trainee perforator dissection practice. This model offers a suitable substitute for perforator dissection practice, as its implementation within a microsurgery training course improves resident comfort and confidence.
RESUMEN
PURPOSE: Informed by prior research and influenced by concerns that the COVID-19 pandemic heightened social isolation, this project examined the impact of a 12-month long letter writing project on levels of loneliness. METHOD: Through partnerships with local anti-poverty agencies, pen pals were paired between MSW students and community members who utilize services at these organizations. Participants completed the UCLA Loneliness Scale before and after the intervention. RESULTS: We found a mean decrease in loneliness at the end of the intervention. DISCUSSION: Letter writing was a successful way to attend to loneliness due to its accessibility to the participants. Our letter writing intervention is different in many ways from e-mail and texting. Participants noted that the waiting process between letter gave them time to think more deeply about their response as well as event to look forward to (e.g. getting mail). We found that the low-tech aspects of the project might have been helpful to some participants. CONCLUSION: Letter writing is an easily replicable, low-cost, low-tech activity for use by practitioners, which may be useful in a variety of social work settings to reduce loneliness.

Despite the large number of U.S. adults who overweight or obese, few providers have ready access to comprehensive lifestyle interventions, the cornerstone of medical obesity management. Our goal was to establish a research infrastructure embedded in a comprehensive lifestyle intervention treatment for obesity. The Obesity Treatment Research Program (OTRP) is a multi-specialty project at Mayo Clinic in Rochester, Minnesota designed to provide a high intensity, year-long, comprehensive lifestyle obesity treatment. The program includes a nutritional intervention designed to reduce energy intake, a physical activity program and a cognitive behavioral approach to increase the likelihood of long-term adherence. The behavioral intervention template incorporated the Diabetes Prevention Program and the Look AHEAD trial materials. The OTRP is consistent with national recommendations for the management of overweight and obesity in adults, but with embedded features designed to identify patient characteristics that might help predict outcomes, assure long-term follow up and support various research initiatives. Our goal was to develop approaches to understand whether there are patient characteristics that predict treatment outcomes.
RESUMEN
INTRODUCTION: E-consultations are asynchronous text-based consultations between providers which can facilitate patient access to timely specialty care. In contrast to traditional face-to-face consults, conveying and completing recommendations of the specialist is the responsibility of the referring provider. This presents a new workflow for primary care providers who have multiple options (face-to-face, telephone, letter, secure message) to communicate the e-consultation recommendations. This study examines how primary care providers are managing this new workflow. METHODS: We performed a retrospective random sampling of e-consultations with individual medical record review and classified e-consultations by type of recommendation, how recommendations were communicated to patients, and whether recommendations were carried out. RESULTS: We randomly selected 220 e-consultations in 13 different specialties for review. In all, 85% of e-consultations contained recommendations for referring providers. Recommendations on medication(s) were most common (35%) followed by recommendations on ordering laboratory tests (29%). In all, 25% of the time e-consultants gave multiple possible courses of action for referring providers to choose from. Patient notification of recommendations was found for 192 (87%) of e-consultations with providers performing the notification 63% of the time and nursing staff performing the notification 37% of the time. The communication back to the patients included communication via nurse telephone calls (37%), provider telephone calls (23%), secure messages (24%), face-to-face visits (11%), and by written correspondence (5%). DISCUSSION: Managing recommendations from e-consultations results in a new workflow for primary care providers. Healthcare institutions that utilize e-consults should be aware of this new workflow. Further study is needed to determine best practices for this task that is now increasing in primary care.
