The generation of electric power is one important source of pollutants such as mercury, sulfur dioxide, nitrogen oxides, and fine particulate matter that can affect the respiratory, cardiovascular, and central nervous systems and cause pregnancy complications. But protecting people from environmental health hazards has become increasingly complex. Air pollutants are often invisible and travel many miles virtually undetected. Nurses can play a critical role in preventive strategies, as well as in the national debate on energy production and dependence on fossil fuels. [ABSTRACT FROM AUTHOR]

Background: The aim of our study was to evaluate the post-release outcomes of incarcerated individuals with opioid use disorder (OUD) treated with extended-release buprenorphine (XRB) in a rural county jail. Administrative data were collected from a pilot program within a jail in Maine that introduced XRB treatment in 2022 and a comparable jail utilizing sublingual buprenorphine (SLB) during the same period to compare post-release outcomes. Log-binomial regression models were used to estimate the risk ratio (RR) and 95% confidence interval (CI) for jail use of XRB vs. SLB on post-release community buprenorphine continuation., Results: From September 2022 to September 2023, 70 individuals who received XRB were released from the pilot jail and 130 individuals who received SLB were released from the comparison jail. After adjusting for age, sex, and buprenorphine use at entry to jail, individuals released from the pilot jail were almost 3 times (adjusted RR = 2.67, 95% CI 1.84, 3.88) as likely to continue community buprenorphine treatment post-release relative to the comparison jail. In addition, utilization of XRB allowed for expanded access to OUD treatment, was well tolerated, and reduced medication diversion., Conclusions: In this pilot program in Maine, XRB treatment during incarceration was associated with higher post-release community buprenorphine continuation when compared to individuals treated with SLB. These findings provide strong evidence for the superiority of XRB vs. SLB for the treatment of OUD in jail settings., (© 2024. The Author(s).)

Background Compared to in-person recruitment, virtual interviewing reduces costs and promotes equity. However, many residency applicants believe that visiting programs helps inform their rank decisions. Objective We assessed the feasibility of and stakeholder opinions about optional in-person visits after virtual interviewing and program rank list finalization. Methods Six internal medicine residency programs conducted virtual recruitment in 2022-2023 and finalized their rank lists 4 weeks before the deadline. Applicants were invited for optional in-person visits after program rank list finalization. Interviewed applicants, program directors, and program administrators were given surveys that included 7-17 questions and employed "skip logic," discrete answers (eg, "yes/no/unsure" or multiple choice), and open-ended questions. Survey questions assessed stakeholders' opinions about the value, equity, and potential downsides of this recruitment process. Results Participating programs interviewed an average of 379 applicants (range 205-534) with 39 (10.3% [39 of 379], range 7.9%-12.8% [33 of 420-51 of 397]) applicants completing in-person visits. Of 1808 interviewed applicants, 464 responded to the survey (26%); 88% (407 of 464) believe a similar optional in-person visit should be offered next year, 75% (347 of 464) found this process equitable, but only 56% (258 of 464) trusted programs not to change their rank lists. Nearly all who attended an in-person visit (96.5%, 109 of 113) found it valuable. All program directors liked the optional in-person visit and believe future applicants should be offered similar in-person visits. Conclusions A large majority of participating applicants and program directors believe that in-person visits should be offered after program rank list finalization. The majority of respondents felt this recruitment process was equitable.

Aim: Little is known about whether pain can be effectively managed in pregnant women with opioid use disorder (OUD) during delivery hospitalization, particularly those undergoing surgery and taking buprenorphine as medication for OUD (MOUD). To address this question, we compared pain scores and opioid analgesic utilization during delivery hospitalization in women taking their pre-hospital dose of buprenorphine who delivered by cesarean section to matched controls. To inform future research efforts, we also began to explore opioid analgesic utilization and pain scores by type of anesthesia as this variable is often not included in related literature., Methods: Retrospective matched cohort study of 46 women prescribed buprenorphine during pregnancy who delivered by cesarean section during a 7-year period., Results: When compared to matched controls, women taking their pre-hospital dose of buprenorphine undergoing cesarean section utilized more opioid analgesics as measured by morphine milligram equivalents (MME) (mean MME first 48 hours 153.0 mg vs 175.1 mg, respectively, P  < .01) but had similar pain scores during delivery hospitalization. There was no difference in MME utilization by maternal dose of buprenorphine though sample sizes were small. Women on buprenorphine who received spinal anesthesia with morphine had mean pain scores that were 1.4 points lower ( P  = .01) during the first 48 hours than women on buprenorphine receiving other methods of anesthesia., Discussion and Conclusions: Pregnant women taking their pre-hospital dose of buprenorphine throughout their surgical delivery hospitalization were able to achieve pain relief similar to women not on MOUD but had higher MME requirements. Our results add to the emerging body of evidence suggesting that individuals on MOUD can achieve adequate post-surgical pain management without adjusting their pre-hospital dose of buprenorphine. Further research is required to fully understand the optimal buprenorphine dosing regimen during surgical hospitalizations. Our results also provide important preliminary evidence that spinal anesthesia containing opioids can be used effectively in individuals with OUD requiring surgical intervention., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Background: Burnout is common among physicians and physician leaders, including residency program directors (PDs). The effects of the COVID-19 pandemic and other stressors in 2020 on PDs is unknown., Objective: To measure the prevalence of burnout among internal medicine (IM) residency PDs 6 months into the COVID-19 pandemic., Methods: A total of 429 IM PDs, representing 83% of accredited residency programs, were surveyed from August to December 2020. Burnout, using a 2-item screening tool, and self-reported consideration of resigning in 2020, were compared to their annual prevalence since 2012 and tested for possible associations with pandemic stressors and program characteristics., Results: The survey response rate was 61.5% (264 of 429). One-third (33.6%, 87 of 259) of PD respondents met burnout criteria, and 45.1% (110 of 244) reported considering resigning in the past year, which were within the range of preceding years. PDs who reported feeling highly supported by institutional leadership were less likely to meet burnout criteria and to have considered resigning. There were no associations between burnout or consideration of resigning and the amount of clinical time PDs spent in their roles, duration of maximum stress on programs, budget cuts to programs, or geographic region., Conclusions: The prevalence of burnout among PDs in fall 2020 was similar to the prevalence of burnout in pre-pandemic years despite uniquely extreme stressors. PDs' perception of being highly supported by institutional leadership was associated with lower prevalence of burnout and consideration of resigning. Perceived leadership support may be a protective factor against burnout during periods of high stress., Competing Interests: Conflict of interest: The authors declare they have no competing interests.

Background: Single-center studies have reported residents experience barriers to accessing supervising physicians overnight, but no national dataset has described barriers perceived by residents or the association between supervision models and perceived barriers., Objective: To explore residents' perception of barriers to accessing overnight supervision., Design: Questions about overnight supervision and barriers to accessing it were included on the American College of Physicians Internal Medicine In-Training Examination® (IM-ITE®) Resident Survey in Fall 2017., Participants: All US-based internal medicine residents who completed the 2017 IM-ITE®. Responses from 20,744 residents (84%) were analyzed., Main Measures: For our main outcome, we calculated percentages of responses for eight barriers and tested for association with the presence or absence of nocturnists. For our secondary outcome, we categorized free-text responses enumerating barriers from all residents into the five Systems Engineering Initiative for Patient Safety (SEIPS) categories to elucidate future areas for study or intervention., Key Results: Internal medicine residents working in hospitals without nocturnists more commonly reported having at least one barrier to accessing a supervising physician "always" or "most of the time" (5075/9842, 51.6%) compared to residents in hospitals with nocturnists (3074/10,902, 28.2%, p < 0.001). Among residents in hospitals without nocturnists, the most frequently reported barrier to accessing attending supervision was attendings not being present in the hospital (30.4% "always" or "most of the time"); residents in hospitals with nocturnists most frequently reported desire to make their own decisions as a barrier to contacting attendings (15.7% "always" or "most of the time"). Free-text responses from residents with and without nocturnists most commonly revealed organization (47%) barriers to accessing supervision; 28% cited person barriers, and 23% cited tools/technology barriers., Conclusions: Presence of nocturnists is associated with fewer reported barriers to contacting supervising physicians overnight. Organizational culture, work schedules, desire for independence, interpersonal interactions, and technology may present important barriers., (© 2021. Society of General Internal Medicine.)

Background: Training residents to become competent in common bedside procedures can be challenging. Some hospitals have attending physician-led procedure teams with oversight of all procedures to improve procedural training, but these teams require significant resources to establish and maintain., Objective: We sought to improve resident procedural training by implementing a resident-run procedure team without routine attending involvement., Methods: We created the role of a resident procedure coordinator (RPC). Interested residents on less time-intensive rotations voluntarily served as RPC. Medical providers in the hospital contacted the RPC through a designated pager when a bedside procedure was needed. A structured credentialing process, using direct observation and a procedure-specific checklist, was developed to determine residents' competence for completing procedures independently. Checklists were developed by the residency program and approved by institutional subspecialists. The service was implemented in June 2016 at an 850-bed academic medical center with 70 internal medicine and 32 medicine-pediatrics residents. The procedure service functioned without routine attending involvement. The impact was evaluated through resident procedure logs and surveys of residents and attending physicians., Results: Compared with preimplementation procedure logs, there were substantial increases postimplementation in resident-performed procedures and the number of residents credentialed in paracenteses, thoracenteses, and lumbar punctures. Fifty-nine of 102 (58%) residents responded to the survey, with 42 (71%) reporting the initiative increased their ability to obtain procedural experience. Thirty-one of 36 (86%) attending respondents reported preferentially using the service., Conclusions: The RPC model increased resident procedural training opportunities using a structured sign-off process and an operationalized service., Competing Interests: Conflict of interest: The authors declare they have no competing interests.

Background : In May 2017, the Alliance for Academic Internal Medicine (AAIM) published guidelines intending to standardize and improve internal medicine residency program director (PD) letters of recommendation (LORs) for fellowship applicants. Objectives : This study aimed to examine fellowship PDs impressions of the new guidelines, letter writers' adherence to the guidelines, and the impact of LORs that conformed to guidelines compared to non-standardized letters. Methods : The authors anonymously surveyed fellowship PDs from January to March 2018 to gather input about LORs submitted to their programs during the 2017 fellowship application cycle. Results : A total of 78% of survey respondents were satisfied with letters that followed the AAIM guidelines, whereas 48% of respondents were satisfied with letters that did not. Fellowship PDs felt that letters that followed the AAIM guidelines were more helpful than letters that did not, especially for differentiating between applicants from the same institution and for understanding residents' performance across the six core competency domains. Fellowship PDs provided several suggestions for residency PDs to make the LORs even more helpful. Conclusion : Fellowship PD respondents indicated that LORs that followed the new AAIM guidelines were more helpful than letters that did not.

Some internal medicine residency program directors have expressed concerns that their third-year residents may have been subjected to inappropriate communication during the 2016 fellowship recruitment season. The authors sought to study applicants' interpersonal communication experiences with fellowship programs. Many respondents indicated that they had been asked questions that would constitute violations of the National Residency Matching Program (NRMP) Communications Code of Conduct agreement, including how they plan to rank specific programs. Moreover, female respondents were more likely to have been asked questions during interview experiences about other programs to which they applied, and about their family plans. Post-interview communication policies were not made clear to most applicants. These results suggest ongoing challenges for the internal medicine community to improve communication with applicants and uniform compliance with the NRMP communications code of conduct during the fellowship recruitment process., Competing Interests: No potential conflict of interest was reported by the authors.​

The Neuropathic Pain Special Interest Group of the International Association for the Study of Pain recently sponsored the development of evidence-based guidelines for the pharmacological treatment of neuropathic pain. Tricyclic antidepressants, dual reuptake inhibitors of serotonin and norepinephrine, calcium channel alpha(2)-delta ligands (ie, gabapentin and pregabalin), and topical lidocaine were recommended as first-line treatment options on the basis of the results of randomized clinical trials. Opioid analgesics and tramadol were recommended as second-line treatments that can be considered for first-line use in certain clinical circumstances. Results of several recent clinical trials have become available since the development of these guidelines. These studies have examined botulinum toxin, high-concentration capsaicin patch, lacosamide, selective serotonin reuptake inhibitors, and combination therapies in various neuropathic pain conditions. The increasing number of negative clinical trials of pharmacological treatments for neuropathic pain and ambiguities in the interpretation of these negative trials must also be considered in developing treatment guidelines. The objectives of the current article are to review the Neuropathic Pain Special Interest Group guidelines for the pharmacological management of neuropathic pain and to provide a brief overview of these recent studies.

Currently, an estimated 38 million individuals 65 years or older live in the United States, and more than 11 million of these individuals are 80 years or older. Older people are at high risk of neuropathic pain because many diseases that cause neuropathic pain increase in incidence with age. Depending on their underlying health, older adults with neuropathic pain may have to cope with multiple coexisting diseases, polypharmacy, and impaired functional ability. The objective of this article is to review how aging and frailty affect the treatment of older adults with neuropathic pain. Specific topics reviewed include the complexity of treatment decisions in older patients due to aged heterogeneity, multimorbidity, and polypharmacy; selection of treatment in an effort to maximize patients' functional abilities in addition to relieving their pain; more careful dosing (usually lower) and monitoring of pharmacotherapy relative to younger patients due to age-related changes in pharmacokinetics and pharmacodynamics; and underrepresentation of older adults in clinical trials of neuropathic pain treatments, which further compromises physicians' ability to make informed treatment decisions.

Background: Teaching hospitals increasingly rely on transfers of patient care to another physician (hand-offs) to comply with duty hour restrictions. Little is known about the impact of hand-offs on medical students., Objective: To evaluate the impact of hand-offs on the types of patients students see and the association with their subsequent Medicine Subject Exam performance., Design: Observational study over 1 year., Participants: Third-year medical students in an Inpatient Medicine Clerkship at five hospitals with night float systems., Primary Outcome: Medicine Subject Exam at the end of the clerkship; explanatory variables: number of fresh (without prior evaluation) and hand-off patients, diagnoses, subspecialty patients, and full evaluations performed during the clerkship, and United Stated Medical Licensing Examination (USMLE) Step I scores., Main Results: Of the 2,288 patients followed by 89 students, 990 (43.3%) were hand-offs. In a linear regression model, the only variables significantly associated with students' Subject Exam percentile rankings were USMLE Step I scores (B = 0.26, P < 0.001) and the number of full evaluations completed on fresh patients (B =0.20, P = 0.048; model r (2) = 0.58). In other words, for each additional fresh patient evaluated, Subject Exam percentile rankings increased 0.2 points. For students in the highest quartile of Subject Exam percentile rankings, only Step I scores showed a significant association (B = 0.22, P = 0.002; r (2) = 0.5). For students in the lowest quartile, only fresh patient evaluations demonstrated a significant association (B = 0.27, P = 0.03; r (2) = 0.34)., Conclusions: Hand-offs constitute a substantial portion of students' patients and may have less educational value than "fresh" patients, especially for lower performing students.

Objectives: Pain management continues to be suboptimal in emergency departments (EDs). Several studies have documented failures in the processes of care, such as whether opioid analgesics were given. The objectives of this study were to measure the outcomes following administration of intravenous (IV) opioids and to identify clinical factors that may predict poor analgesic outcomes in these patients., Methods: In this prospective cohort study, emergency patients were enrolled if they were prescribed IV morphine or hydromorphone (the most commonly used IV opioids in the study hospital) as their initial analgesic. Patients were surveyed at the time of opioid administration and 1 to 2 hours after the initial opioid dosage. They scored their pain using a verbal 0-10 pain scale. The following binary analgesic variables were primarily used to identify patients with poor analgesic outcomes: 1) a pain score reduction of less than 50%, 2) a postanalgesic pain score of 7 or greater (using the 0-10 numeric rating scale), and 3) the development of opioid-related side effects. Logistic regression analyses were used to study the effects of demographic, clinical, and treatment covariates on the outcome variables., Results: A total of 2,414 were approached for enrollment, of whom 1,312 were ineligible (658 were identified more than 2 hours after IV opioid was administered and 341 received another analgesic before or with the IV opioid) and 369 declined to consent. A total of 691 patients with a median baseline pain score of 9 were included in the final analyses. Following treatment, 57% of the cohort failed to achieve a 50% pain score reduction, 36% had a pain score of 7 or greater, 48% wanted additional analgesics, and 23% developed opioid-related side effects. In the logistic regression analyses, the factors associated with poor analgesia (both <50% pain score reduction and postanalgesic pain score of >or=7) were the use of long-acting opioids at home, administration of additional analgesics, provider concern for drug-seeking behavior, and older age. An initial pain score of 10 was also strongly associated with a postanalgesic pain score of >or=7. African American patients who were not taking opioids at home were less likely to achieve a 50% pain score reduction than other patients, despite receiving similar initial and total equianalgesic dosages. None of the variables we assessed were significantly associated with the development of opioid-related side effects., Conclusions: Poor analgesic outcomes were common in this cohort of ED patients prescribed IV opioids. Patients taking long-acting opioids, those thought to be drug-seeking, older patients, those with an initial pain score of 10, and possibly African American patients are at especially high risk of poor analgesia following IV opioid administration., ((c) 2009 by the Society for Academic Emergency Medicine.)

c-Met is a receptor tyrosine kinase often deregulated in human cancers, thus making it an attractive drug target. One mechanism by which c-Met deregulation leads to cancer is through gain-of-function mutations. Therefore, small molecules capable of targeting these mutations could offer therapeutic benefits for affected patients. SU11274 was recently described and reported to inhibit the activity of the wild-type and some mutant forms of c-Met, whereas other mutants are resistant to inhibition. We identified a novel series of c-Met small molecule inhibitors that are active against multiple mutants previously identified in hereditary papillary renal cell carcinoma patients. AM7 is active against wild-type c-Met as well as several mutants, inhibits c-Met-mediated signaling in MKN-45 and U-87 MG cells, and inhibits tumor growth in these two models grown as xenografts. The crystal structures of AM7 and SU11274 bound to unphosphorylated c-Met have been determined. The AM7 structure reveals a novel binding mode compared with other published c-Met inhibitors and SU11274. The molecule binds the kinase linker and then extends into a new hydrophobic binding site. This binding site is created by a significant movement of the C-helix and so represents an inactive conformation of the c-Met kinase. Thus, our results demonstrate that it is possible to identify and design inhibitors that will likely be active against mutants found in different cancers.

Objective: The slow rate at which articular cartilage degrades in dogs after transection of the anterior cruciate ligament (ACLT) has been attributed to capsular thickening and buttressing by osteophytes. We investigated the roles of the peripheral and central nervous systems in protecting knee joints with chronic ACL deficiency from breakdown., Methods: Five groups of dogs were studied; all were killed 72 weeks after left knee surgery. Group A had ACLT, group B had ACLT followed 52 weeks later by ipsilateral L4-S1 dorsal root ganglionectomy (DRG), group C had DRG followed 2 weeks later by ACLT, group D had sham DRG followed 2 weeks later by ACLT, and group E had DRG followed 2 weeks later by sham ACTL., Results: Group E dogs did not develop knee pathology. All cruciate-deficient knees were lax at the end of the study. The osteoarthritis (OA) that developed in groups A, B, and D was comparable (P > 0.05), and was significantly greater than that in group E (P < 0.05). Group C developed much more severe OA than any of the other groups (P < 0.05)., Conclusion: Ipsilateral sensory input is temporarily important in protecting the unstable joint from rapid breakdown. Over time, the central nervous system apparently acquires the ability to protect the unstable joint without continued ipsilateral sensory input.
