Poor personal financial health has been linked to key components of health including burnout, substance abuse, and worsening personal relationships. Understanding the state of resident financial health is key to improving their overall wellbeing.A secondary analysis of a survey of New England general surgery resident was performed to understand their financial wellbeing. Questions from the National Financial Capability Study were used to compare to an age- and regionally matched cohort.Overall, 44% (250/570) of surveyed residents responded. Residents more frequently reported spending less than their income each year compared to the control cohort (54% vs 34% , p0.01). However, 17% (39/234) of residents reported spending more than their income each year. Sixty five percent of residents (152/234), found it "not at all difficult" to pay monthly bills versus 17% (76/445) of the control cohort (p0.01). However, 32% (75/234) of residents reported it was "Somewhat" or "Very" difficult to pay monthly bills. Residents more frequently reported they "certainly" or "probably" could "come up with" $2000 in a month compared to the control cohort (85% vs 62% p0.01). But 16% (37/234) of residents reported they could not. In this survey, 21% (50/234) of residents reported having a personal life insurance policy, 25% (59/234) had disability insurance, 6% (15/234) had a will, and 27% (63/234) had$300,000 worth of student loans.Surgical residents have better financial wellbeing than an age- and regionally-matched cohort, but there is still a large proportion who suffer from financial difficulties.

Surgical culture has shifted to recognize the importance of resident well-being. This is the first study to longitudinally track regional surgical resident well-being over 5 years.An anonymous cross-sectional, multi-institutional survey of New England general surgery residents using novel and published instruments to create three domains: health maintenance, burnout, and work environment.Overall, 75% (15 of 20) of programs participated. The response rate was 44% (250 of 570), and 53% (133 of 250) were women, 94% (234 of 250) were 25 to 34 years old, and 71% (178 of 250) were in a relationship. For health maintenance, 57% (143 of 250) reported having a primary care provider, 26% (64 of 250) had not seen a primary care provider in 2 years, and 59% (147 of 250) endorsed being up to date with age-appropriate health screening, but only 44% (109 of 250) were found to actually be up to date. Only 14% (35 of 250) reported exercising more than 150 minutes/week. The burnout rate was 19% (47 of 250), with 32% (81 of 250) and 25% (63 of 250) reporting high levels of emotional exhaustion and depersonalization, respectively. For program directors and attendings, 90% of residents reported that they cared about resident well-being. Eighty-seven percent of residents believed that it was acceptable to take time off during the workday for a personal appointment, but only 49% reported that they would personally take the time.The personal health maintenance of general surgery residents has changed little over the past five years, despite an overwhelming majority of residents reporting that attendings and program directors care about their well-being. Further study is needed to understand the barriers to improvement of resident wellbeing.

To describe the first year of the Educational Quality Improvement Program (EQIP) DESIGN: The Educational Quality Improvement Program (EQIP) was formed by the Association of Program Directors in Surgery (APDS) in 2018 as a continuous educational quality improvement program. Over 18 months, thirteen discrete goals for the establishment of EQIP were refined and executed through a collaborative effort involving leaders in surgical education. Alpha and beta pilots were conducted to refine the data queries and collection processes. A highly-secure, doubly-deidentified database was created for the ingestion of resident and program data.36 surgical training programs with 1264 trainees and 1500 faculty members were included in the dataset. 51,516 ERAS applications to programs were also included. Uni- and multi-variable analysis was then conducted.EQIP was successfully deployed within the timeline described in 2020. Data from the ACGME, ABS, and ERAS were merged with manually entered data by programs and successfully ingested into the EQIP database. Interactive dashboards have been constructed for use by programs to compare to the national cohort. Risk-adjusted multivariable analysis suggests that increased time in a technical skills lab was associated with increased success on the ABS's Qualifying Examination, alone. Increased time in a technical skills lab and the presence of a formal teaching curriculum were associated with increased success on both the ABS's Qualifying and Certifying Examination. Program type may be of some consequence in predicting success on the Qualifying Examination.The APDS has proved the concept that a highly secure database for the purpose of continuous risk-adjusted quality improvement in surgical education can be successfully deployed. EQIP will continue to improve and hopes to include an increasing number of programs as the barriers to participation are overcome.

We modeled cross-well strain/strain rate responses of fiber optic sensing, including distributed strain sensing (DSS) and low-frequency distributed acoustic sensing (DAS), to hydraulic stimulation. DSS and low-frequency DAS have been used to measure strain or the strain rate to characterize hydraulic fractures. However, the current application of DSS/DAS is limited to acquisition, processing, and qualitative interpretations. The lack of geomechanical models hinders the development of the technology toward quantitative interpretation and inversion. We have developed a strategy to use the displacement discontinuity method to model the strain field around kinematically propagating fractures. For a horizontal monitoring well, modeling results were able to explain the heart-shaped extending pattern before a fracture hit, the polarity flip due to fracture interaction during stimulation, and the V-shaped pattern when a fracture does not intersect with the monitoring well. For a vertical monitoring well, modeling shows the different characters of strain rate responses when a fracture is near and far away from a vertical monitoring well. We also investigated the effects of fractures with various geometries such as elliptic and layered fractures. We compared and verified the modeling with field data from the Hydraulic Fracturing Test Site 2, a research experiment performed in the Permian Basin. Our modeling work can be used to identify patterns in field observations. The results also help to improve acquisition design and lay the groundwork for quantitative interpretation and inversion.

Induced hyperthermia has been demonstrated as an effective oncological treatment due to the reduced heat tolerance of most malignant tissues; however, most techniques for heat generation within a target volume are insufficiently selective, inducing heating and unintended damage to surrounding healthy tissues. Plasmonic photothermal therapy (PPTT) utilizes light in the near-infrared (NIR) region to induce highly localized heating in gold nanoparticles, acting as exogenous chromophores, while minimizing heat generation in nearby tissues. However, optimization of treatment parameters requires extensive in vitro and in vivo studies for each new type of pathology and tissue targeted for treatment, a process that can be substantially reduced by implementing computational modeling. Herein, we describe the development of an innovative model based on the finite element method (FEM) that unites photothermal heating physics at the nanoscale with the micron scale to predict the heat generation of both single and arrays of gold nanoparticles. Plasmonic heating from laser illumination is computed for gold nanoparticles with three different morphologies: nanobipyramids, nanorods, and nanospheres. Model predictions based on laser illumination of nanorods at a visible wavelength (655 nm) are validated through experiments, which demonstrate a temperature increase of 5 °C in the viscinity of the nanorod array when illuminated by a 150 mW red laser. We also present a predictive model of the heating effect induced at 810 nm, wherein the heating efficiencies of the various morphologies sharing this excitation peak are compared. Our model shows that the nanorod is the most effective at heat generation in the isolated scenario, and arrays of 91 nm long nanorods reached hyperthermic levels (an increase of at least 5 °C) within a volume of over 20 μm(3).

The incidence of esophageal cancer (EC) is on the rise. With the distinct subtypes of adenocarcinoma and squamous cell carcinoma comes specific risk factors, and as a result, people of certain regions of the world can be more prone to a subtype. For example, squamous cell carcinoma of the esophagus has the highest incidence in eastern Africa and eastern Asia, with smoking being a major risk factor, whereas adenocarcinoma is more prevalent in North America and western Europe, with gastroesophageal reflux disease being a leading risk factor. With that being said, adenocarcinoma and squamous cell carcinoma have similar and unfortunately poor survival rates, partly because EC is prone to early metastasis given that the esophagus does not have a serosa, as well as the superficial nature of its lymphatics compared with the rest of the gastrointestinal tract. This makes early detection of the utmost importance, and certain patients have been shown to have the benefit of screening/surveillance endoscopies, including those with Barrett's esophagus, lye-induced/caustic strictures, tylosis, and Peutz-Jeghers syndrome. Until treatments significantly improve, identifying EC at the earliest stage will have the best success for patient outcomes, and further elucidation of its pathogenesis and risk factors may lead to identifying other high-risk groups that should be screened.
