Diagnostic challenges and individualized treatment of cervical adenocarcinoma metastases to the breast: A case report.

BACKGROUND: Cervical cancer is a rare primary tumor resulting in metastases to the breast with few cases reported in literature. Breast metastases are associated with poor prognosis. The following case highlights the diagnostic challenges associated with metastatic cervical cancer to the breast along with individualized treatment. CASE SUMMARY: A 44-year-old G7P5025 with no significant past medical or surgical history presented with heavy vaginal to an outside emergency department where an exam and a pelvic magnetic resonance imaging showed a 4.5 cm heterogenous lobulated cervical mass involving upper two thirds of vagina, parametria and lymph node metastases. Cervical biopsies confirmed high grade adenocarcinoma with mucinous features. A positron emission tomography/computed tomography (PET/CT) did not show evidence of metastatic disease. She received concurrent cisplatin with external beam radiation therapy. Follow up PET/CT scan three months later showed no suspicious fluorodeoxyglucose uptake in the cervix and no evidence of metastatic disease. Patient was lost to follow up for six months. She was re-imaged on re-presentation and found to have widely metastatic disease including breast disease. Breast biopsy confirmed programmed death-ligand 1 positive metastatic cervical cancer. The patient received six cycles of carboplatin and paclitaxel with pembrolizumab. Restaging imaging demonstrated response. Patient continued on pembrolizumab with disease control. CONCLUSION: Metastatic cervical cancer to the breast is uncommon with nonspecific clinical findings that can make diagnosis challenging. Clinical history and immunohistochemical evaluation of breast lesion, and comparison to primary tumor can support diagnosis of metastatic cervical cancer to the breast. Overall, the prognosis is poor, but immunotherapy can be considered in select patients and may result in good disease response.

A Comparison of Remote vs In-Person Proctored In-Training Examination Administration for Internal Medicine.

PURPOSE: In response to COVID-19, the American College of Physicians provided residents the option to complete the 2020 Internal Medicine In-Training Examination (IM-ITE) via in-person and remote proctoring. This study evaluated the extent to which scores obtained from both testing modalities were comparable. METHOD: Data were analyzed from residents from all U.S.-based Accreditation Council for Graduate Medical Education-accredited IM residency programs and participating Canadian and international programs who completed the IM-ITE in 2020. The final sample contained 27,115 IM residents: 9,205 postgraduate year (PGY) 1, 9,332 PGY-2, and 8,578 PGY-3. Testing modality, gender, PGY, time spent on assessment, and native language were used to predict percent-correct scores in a multilevel regression model. This model included all main effects and all 2-way interactions between testing modality and each resident-level demographic variable, allowing those effects to be controlled for. RESULTS: Of 27,115 residents studied, 11,354 (42%) tested remotely and 15,761 (58%) in person. Across the parameters of interest (main effect of testing modality and 2-way interactions), the only statistically significant effects were the interaction effects between testing mode (interaction effect: -0.61; 95% confidence interval (CI): -1.01, -0.21) and PGY (interaction effect: -0.54; 95% CI: -0.95, -0.13) (P = .002). Differences between in-person and remote predicted scores were slightly larger for PGY-1 than for PGY-2 and PGY-3 residents (controlling for the other predictors in the model), but the magnitude of these differences across residency training was well under a single percentage point. Because these statistically significant effects were deemed educationally nonsignificant, the study concluded that performance did not substantively differ across in-person and remote examinees. CONCLUSIONS: Residents taking the 2020 IM-ITE performed similarly across in-person and remote proctoring. This study provides evidence of score comparability across the 2 testing modalities and supports continued use of remote proctoring for the IM-ITE.

Impact of the COVID-19 pandemic on internal medicine training in the United States: results from a national survey.

BACKGROUND: Internal medicine (IM) residency is a notoriously challenging time generally characterized by long work hours and adjustment to new roles and responsibilities. The COVID-19 pandemic has led to multiple emergent adjustments in training schedules to accommodate increasing needs in patient care. The physician training period, in itself, has been consistently shown to be associated with vulnerability with respect to mental well-being. The impact of the COVID-19 pandemic on the experience of IM trainees is not well established. OBJECTIVE: Characterize the impact of the COVID-19 pandemic on trainee clinical education, finances, and well-being. METHODS: We developed a survey composed of 25 multiple choice questions, 6 of which had an optional short-answer component. The survey was distributed by the American College of Physicians (ACP) to 23,289 IM residents and subspecialty fellows. We received 1,128 complete surveys and an additional 269 partially completed surveys. RESULTS: The majority of respondents reported a disruption in their clinical schedule (76%) and a decrease in both didactic conferences (71%) and protected time for education (56%). A majority of respondents (81%) reported an impact on their well-being with an increase in their level of burnout and 41% of respondents reported a decrease in level of direct supervision. Despite these changes, the majority of trainee respondents (78%) felt well prepared for clinical practice after graduation. CONCLUSIONS: These results outline the vulnerable position of internal medicine physicians in training. Preserving educational experiences, adequate supervision, and humane work hours are essential in protecting trainees from mental illness and burnout during global emergencies.

Tobacco Smoking and Survival Following a Diagnosis with Ovarian Cancer.

BACKGROUND: Little is known about the influence of smoking on ovarian cancer survival. We investigated this relationship in a hospital-based study. METHODS: Analyses included 519 women with ovarian cancer. We used multivariable adjusted Cox proportional hazards regression models to estimate HRs and 95% confidence intervals (CI). RESULTS: Risk of all-cause mortality was increased for current smokers (HR = 1.70; 95% CI: 1.09-2.63) versus never smokers, especially for those with ≥15 cigarettes per day (HR = 1.92; 95% CI: 1.15-3.20). Results were largely similar after additional adjustment for debulking status (current vs. never smokers, HR = 2.96; 95% CI: 1.07-8.21) or neoadjuvant chemotherapy (comparable HR = 2.87; 95% CI: 1.02-8.06). Compared with never smokers, smoking duration ≥20 years (HR = 1.38; 95% CI: 0.94-2.03) and ≥20 pack-years (HR = 1.35; 95% CI: 0.92-1.99) were suggestively associated with worse outcomes. Current smoking was also positively associated with the risk of mortality among patients with ovarian cancer recurrence (current vs. never/past smokers, HR = 2.79; 95% CI: 1.44-5.41), despite the null association between smoking and recurrence (HR = 1.46; 95% CI: 0.86-2.48). Furthermore, no association was observed for smoking initiation before age 18 (HR = 1.22; 95% CI: 0.80-1.85), or either environmental smoke exposure at home (HR = 1.16; 95% CI: 0.76-1.78) or at work (HR = 1.10; 95% CI: 0.75-1.60). CONCLUSIONS: Our results suggest active tobacco smoking is associated with worse ovarian cancer outcomes, particularly after a recurrence. IMPACT: Our findings support structured smoking cessation programs for patients with ovarian cancer, especially in recurrent settings. Further research to confirm these findings and examine the interplay between smoking and the tumor immune microenvironment may help provide insight into ovarian cancer etiology.

A survey of internists' recommendations for aspirin in older adults and barriers to evidence-based use.

Recent trials suggest that aspirin for primary prevention may do more harm than good for some, including adults over 70 years of age. We sought to assess how primary care providers (PCPs) use aspirin for the primary prevention in older patients and to identify barriers to use according to recent guidelines, which recommend against routine use in patients over age 70. We surveyed PCPs about whether they would recommend aspirin in clinical vignettes of a 75-year-old patient with a 10-year atherosclerotic cardiovascular disease risk of 25%. We also queried perceived difficulty following guideline recommendations, as well as perceived barriers and facilitators. We obtained responses from 372 PCPs (47.9% response). In the patient vignette, 45.4% of clinicians recommended aspirin use, which did not vary by whether the patient was using aspirin initially (p = 0.21); 41.7% believed aspirin was beneficial. Perceived barriers to guideline-based aspirin use included concern about patients being upset (41.6%), possible malpractice claims (25.0%), and not having a strategy for discussing aspirin use (24.5%). The estimated adjusted probability of rating the guideline as "hard to follow" was higher in clinicians who believed aspirin was beneficial (29.4% vs. 8.0%; p < 0.001) and who worried the patient would be upset if told to stop aspirin (26.7% vs. 12.5%; p = 0.001). Internists vary considerably in their recommendations for aspirin use for primary prevention in older patients. A high proportion of PCPs continue to believe aspirin is beneficial in this setting. These results can inform de-implementation efforts to optimize evidence-based aspirin use.

A national study of moral distress among U.S. internal medicine physicians during the COVID-19 pandemic.

BACKGROUND: There have been no studies to date of moral distress during the COVID-19 pandemic in national samples of U.S. health workers. The purpose of this study was to determine, in a national sample of internal medicine physicians (internists) in the U.S.: 1) the intensity of moral distress; 2) the predictors of moral distress; 3) the outcomes of moral distress. METHODS: We conducted a national survey with an online panel of internists, representative of the membership of the American College of Physicians, the largest specialty organization of physicians in the United States, between September 21 and October 8, 2020. Moral distress was measured with the Moral Distress Thermometer, a one-item scale with a range of 0 ("none") to 10 ("worst possible"). Outcomes were measured with short screening scales. RESULTS: The response rate was 37.8% (N = 810). Moral distress intensity was low (mean score = 2.4, 95% CI, 2.2-2.6); however, 13.3% (95% CI, 12.1% - 14.5%) had a moral distress score greater than or equal to 6 ("distressing"). In multiple linear regression models, perceived risk of death if infected with COVID-19 was the strongest predictor of higher moral distress (ß (standardized regression coefficient) = 0.26, p < .001), and higher perceived organizational support (respondent belief that their health organization valued them) was most strongly associated with lower moral distress (ß = -0.22, p < .001). Controlling for other factors, high levels of moral distress, but not low levels, were strongly associated (adjusted odds ratios 3.0 to 11.5) with screening positive for anxiety, depression, posttraumatic stress disorder, burnout, and intention to leave patient care. CONCLUSIONS: The intensity of moral distress among U.S. internists was low overall. However, the 13% with high levels of moral distress had very high odds of adverse mental health outcomes. Organizational support may lower moral distress and thereby prevent adverse mental health outcomes.

Effects of Healthcare Organization Actions and Policies Related to COVID-19 on Perceived Organizational Support Among U.S. Internists: A National Study.

GOAL: Perceived organizational support (POS) may promote healthcare worker mental health, but organizational factors that foster POS during the COVID-19 pandemic are unknown. The goals of this study were to identify actions and policies regarding COVID-19 that healthcare organizations can implement to promote POS and to evaluate the impact of POS on physicians' mental health, burnout, and intention to leave patient care. METHODS: We conducted a cross-sectional national survey with an online panel of internal medicine physicians from the American College of Physicians in September and October of 2020. POS was measured with a 4-item scale, based on items from Eisenberger's Perceived Organizational Support Scale that were adapted for the pandemic. Mental health outcomes and burnout were measured with short screening scales. PRINCIPAL FINDINGS: The response rate was 37.8% (N = 810). Three healthcare organization actions and policies were independently associated with higher levels of POS in a multiple linear regression model that included all actions and policies as well as potential confounding factors: opportunities to discuss ethical issues related to COVID-19 (ß (regression coefficient) = 0.74, p = .001), adequate access to personal protective equipment (ß = 1.00, p = .005), and leadership that listens to healthcare worker concerns regarding COVID-19 (ß = 3.58, p < .001). Sanctioning workers who speak out on COVID-19 safety issues or refuse pandemic deployment was associated with lower POS (ß = -2.06, p < .001). In multivariable logistic regression models, high POS was associated with approximately half the odds of screening positive for generalized anxiety, depression, post-traumatic stress disorder, burnout, and intention to leave patient care within 5 years. APPLICATIONS TO PRACTICE: Our results suggest that healthcare organizations may be able to increase POS among physicians during the COVID-19 pandemic by guaranteeing adequate personal protective equipment, making sure that leaders listen to concerns about COVID-19, and offering opportunities to discuss ethical concerns related to caring for patients with COVID-19. Other policies and actions such as rapid COVID-19 tests may be implemented for the safety of staff and patients, but the policies and actions associated with POS in multivariable models in this study are likely to have the largest positive impact on POS. Warning or sanctioning workers who refuse pandemic deployment or speak up about worker and patient safety is associated with lower POS and should be avoided. We also found that high degrees of POS are associated with lower rates of adverse outcomes. So, by implementing the tangible support policies positively associated with POS and avoiding punitive ones, healthcare organizations may be able to reduce adverse mental health outcomes and attrition among their physicians.

Sensory Stimulation of the Foot and Ankle Early Post-stroke: A Pilot and Feasibility Study.

Background: Somatosensory stimulation of the lower extremity could improve motor recovery and walking post-stroke. This pilot study investigated the feasibility of a subsequent randomized controlled trial (RCT) to determine whether task-specific gait training is more effective following either (a) intensive hands-on somatosensory stimulation or (b) wearing textured insoles. Objectives: Determine recruitment and attrition rates, adherence to intervention, acceptability and viability of interventions and outcome measures, and estimate variance of outcome data to inform sample size for a subsequent RCT. Methods: Design: randomized, single-blinded, mixed-methods pilot study. Setting: In-patient rehabilitation ward and community. Participants: n = 34, 18+years, 42-112 days following anterior or posterior circulation stroke, able to follow simple commands, able to walk independently pre-stroke, and providing informed consent. Intervention: Twenty 30-min sessions of task-specific gait training (TSGT) (delivered over 6 weeks) in addition to either: (a) 30-60 min mobilization and tactile stimulation (MTS); or (b) unlimited textured insole (TI) wearing. Outcomes: Ankle range of movement (electrogoniometer), touch-pressure sensory thresholds (Semmes Weinstein Monofilaments), motor impairment (Lower Extremity Motricity Index), walking ability and speed (Functional Ambulation Category, 5-m walk test, pressure insoles) and function (modified Rivermead Mobility Index), measured before randomization, post-intervention, and 1-month thereafter (follow-up). Adherence to allocated intervention and actual dose delivered (fidelity) were documented in case report forms and daily diaries. Focus groups further explored acceptability of interventions and study experience. Analysis: Recruitment, attrition, and dose adherence rates were calculated as percentages of possible totals. Thematic analysis of daily diaries and focus group data was undertaken. Standard deviations of outcome measures were calculated and used to inform a sample size calculation. Results: Recruitment, attrition, and adherence rates were 48.57, 5.88, and 96.88%, respectively. Focus groups, daily-diaries and case report forms indicated acceptability of interventions and outcome measures to participants. The 5-m walk was selected as primary outcome measure for a future trial [mean (SD) at end of intervention: 16.86 (11.24) MTS group and 21.56 (13.57) TI group]; sample size calculation indicated 60 participants are required per group. Conclusion: Recruitment, attrition and adherence rates and acceptability of interventions and outcomes justify a subsequent powered RCT of MTS+TSGT compared with TI+TSGT.

Qualitative assessment of knowledge and attitudes towards cervical cancer screening among male Latino immigrants in Houston, Texas.

BACKGROUND: Male spouses and partners play an important role in determining a woman's willingness to participate in cervical cancer screening. However, the attitudes and behaviors by which they influence a woman's decision to undergo Pap testing remain poorly understood. METHODS: A series of semi-structured, qualitative interviews were conducted in Spanish with 19 recent Latino immigrants in Houston, Texas. The interview format was designed to establish each individual's pattern of engagement with the United States healthcare system, assess baseline knowledge of cervical cancer screening and evaluate attitudes and patterns of communication with their female partners regarding health care. Interview questions were constructed using principles of the Theory of Reasoned Action. All interviews were conducted in Spanish. After translation, responses were coded and scored with the goal of identifying themes and key observations. RESULTS: Most subjects reported few, if any, interactions with the healthcare system since their arrival in the United States. Although most participants reported being aware that women should be seen by their doctors regularly, fewer than half could clearly indicate the purpose of a Pap test or could state with certainty the last time their female partner had undergone screening. Multiple subjects expressed a general distrust of the health care system and concern for its costs. Approximately half of subjects reported that they accompanied their female partner to the health care provider's office and none of the participants reported that they were present in examination rooms at the time their partner underwent screening. Multiple participants endorsed that there may be some concerns within their community regarding women receiving frequent gynecologic care and distrust of the healthcare system. Almost all interviewed subjects stated that while they would allow their female partners to see male physicians, they also expressed the opinion that other men might be uncomfortable with this and that women would likely be more comfortable with female physicians. CONCLUSIONS: Strategies to enhance knowledge of HPV and cancer screening and improve trust in the health care system among male spouses or partners should be explored with the goal of promoting cervical cancer screening among immigrant Latinx populations.

U.S. Internists' Perspectives on Discussing Cost of Care With Patients: Structured Interviews and a Survey.

Background: Rising out-of-pocket costs are creating a need for cost conversations between patients and physicians. Objective: To understand the factors that influence physicians to discuss and consider cost during a patient encounter. Design: Mixed-methods study using semistructured interviews and a survey. Setting: United States. Participants: 20 internal medicine physicians were interviewed; 621 internal medicine physician members of the American College of Physicians completed the survey. Measurements: Interviews were analyzed by using thematic analysis, and surveys were analyzed by using descriptive statistics. Results: From the interviews, 4 themes were identified: Physicians are 1) aware that patients are struggling to afford medical care; 2) relying on clues from patients that hint at their cost sensitivity; 3) relying on experience to anticipate potentially high-cost treatments; and 4) aware that patients are making financial trade-offs to afford their care. Three quarters (n = 466) of survey respondents stated that they consider out-of-pocket costs when making most clinical decisions. For 31% (n = 191) of participants, there were times in the past year that they wanted to discuss out-of-pocket prescription drug costs with patients but did not. The most influential factors for ordering a test are the desire to be as thorough as possible (71% [n = 422]) and insurance coverage for the test (68% [n = 422]). Limitation: Findings are self-reported, the sample is limited to a single specialty, the survey response rate was low, information on the patient population was limited, and the survey instrument is not validated. Conclusion: Physicians are attuned to the burden of health care costs and are willing to consider alternative options based on a patient's cost sensitivity.

Nursing research's ivory tower was knocked down long ago.

As a retired research nurse whose career spanned nearly 50 years, I am well qualified to challenge the view that nursing research used to consist of 'obscure studies carried out in distant ivory towers' with little connection to actual nurses (editorial, April 6).

Use of reflexivity in a mixed-methods study.

AIM: To present a novice researcher's use of a reflective research diary in the quantitive measure of a mixed methods study and to recommend resulting changes to practice. BACKGROUND: Reflexivity is often regarded as a useful tool for ensuring the standard of qualitative research. Reflexivity provides transparent information about the positionality and personal values of the researcher that could affect data collection and analysis; this research process is deemed to be best practice. A reflective research diary also allows researchers to record observations about the research process. However, such diaries are rarely used in quantitative research and are even contraindicated. DATA SOURCES: A reflective research diary maintained while conducting a retrospective audit of 150 hospice casenotes. REVIEW METHODS: A reflective research diary was written at the end of every research session to keep a detailed history of the research process and to critically reflect on the researcher's thoughts, feelings and observations on the day's work. DISCUSSION: This paper raises questions about whether reflexivity is appropriate in quantitative research, whether it has the capacity to add something of value or whether it endangers the robustness of the method. The authors consider the place of grounded theory's commitment to reflexivity in this mixed-methods study and discuss whether reflexivity offers any benefits to researcher development. CONCLUSION: Use of reflexivity had a positive impact on the progress of the quantitative measure of this study: it enabled work to be reviewed efficiently and served to inform future research practice. Reflexivity stimulated the acquisition of researcher skills and contributed positively to the development of confidence in the novice researcher. IMPLICATIONS FOR RESEARCH/PRACTICE: Reflexivity in quantitative research practice can be an effective, ongoing means of critically reviewing work, process and researcher development. Reflexivity is recommended to other quantitative researchers.

A question of quality.

RCN fellows consider the challenges to care in their areas of expertise in a series of six articles, starting this week with education.

Patients' opinions of acute chest pain care: a qualitative evaluation of Chest Pain Units.

AIM: This paper is a report of a study to explore the experiences of individuals receiving Chest Pain Unit care and routine Emergency Department care for acute chest pain. BACKGROUND: Chest Pain Units were established in the United States of America with the aim of reducing admissions and costs, whilst improving quality of life and care satisfaction. Trials showed these units to be safe and practical; however, there was a need to establish whether Chest Pain Units could be cost-effective in the United Kingdom, and whether use of a nurse-led protocol could be acceptable to patients. METHOD: We carried out 26 semi-structured interviews in 2005-2006 with patients across seven trial Chest Pain Units in the United Kingdom (14 in intervention sites and 12 in control sites) to explore issues that patients considered were important in their care experiences, and to develop possible explanations for the main trial outcomes. We analysed transcripts using the Framework approach to identify themes relating to care experiences. FINDINGS: Differences in care experiences were more distinct between individual sites than between control and intervention sites. Satisfaction with care was high overall. Interactions with healthcare professionals, in particular specialist nurses, were valued in terms of reassurance, calming effect and competence. Indications for care improvement concerned information-giving about investigations, diagnosis, and self-care advice. Patients with non-cardiac causes needed to feel more supported after discharge. CONCLUSION: Differences between modes of care may not coincide with identified trial outcomes. Qualitative methods can identify aspects of care that improve patient acceptability. The specialist nurse role appears particularly important in providing satisfactory individualized chest pain care.

The zoonotic potential of Mycobacterium avium spp. paratuberculosis: a systematic review.

BACKGROUND: The zoonotic potential of Mycobacterium avium ssp. paratuberculosis (MAP) has been debated for almost a century because of similarities between Johne's Disease (JD) in cattle and Crohn's disease (CD) in humans. Our objective was to evaluate scientific literature investigating the potential association between these two diseases (MAP and CD) and the presence of MAP in retail milk or dairy products using a qualitative systematic review. METHOD: The search strategy included 19 bibliographic databases, 8 conference proceedings, reference lists of 15 articles and contacting 28 topic-related scientists. Two independent reviewers performed relevance screening, quality assessment and data extraction stages of the review. RESULTS: Seventy-five articles were included. Among 60 case-control studies that investigated the association between MAP and CD, 37 were of acceptable quality. Twenty-three studies reported significant positive associations, 23 reported non-significant associations, and 14 did not detect MAP in any sample. Different laboratory tests, test protocols, types of samples and source populations were used in these studies resulting in large variability among studies. Seven studies investigated the association between CD and JD, two challenge trials reported contradictory results, one cross-sectional study did not support the association, and four descriptive studies suggested that isolated MAP is often closely related to cattle isolates. MAP detection in raw and pasteurized milk was reported in several studies. CONCLUSIONS: Evidence for the zoonotic potential of MAP is not strong, but should not be ignored. Interdisciplinary collaboration among medical, veterinary and other public health officials may contribute to a better understanding of the potential routes of human exposure to MAP.

Applicability of phylogenetic methods for characterizing the public health significance of verocytotoxin-producing Escherichia coli strains.

Two phylogenetic methods (multilocus sequence typing [MLST] and a multiplex PCR) were investigated to determine whether phylogenetic classification of verocytotoxin-producing Escherichia coli serotypes correlates with their classification into groups (seropathotypes A to E) based on their relative incidence in human disease and on their association with outbreaks and serious complications. MLST was able to separate 96% of seropathotype D and E serotypes from those that cause serious disease (seropathotypes A to C), whereas the multiplex PCR lacked this level of seropathotype discrimination.

An overview of microbial food safety programs in beef, pork, and poultry from farm to processing in Canada.

Canada's vision for the agri-food industry in the 21st century is the establishment of a national food safety system employing hazard analysis and critical control point (HACCP) principles and microbiological verification tools, with traceability throughout the gate-to-plate continuum. Voluntary on-farm food safety (OFFS) programs, based in part on HACCP principles, provide producers with guidelines for good production practices focused on general hygiene and biosecurity. OFFS programs in beef cattle, swine, and poultry are currently being evaluated through a national recognition program of the Canadian Food Inspection Agency. Mandatory HACCP programs in federal meat facilities include microbial testing for generic Escherichia coli to verify effectiveness of the processor's dressing procedure, specific testing of ground meat for E. coli O157:H7, with zero tolerance for this organism in the tested lot, and Salmonella testing of raw products. Health Canada's policy on Listeria monocytogenes divides ready-to-eat products into three risk categories, with products previously implicated as the source of an outbreak receiving the highest priority for inspection and compliance. A national mandatory identification program to track livestock from the herd of origin to carcass inspection has been established. Can-Trace, a data standard for all food commodities, has been designed to facilitate tracking foods from the point of origin to the consumer. Although much work has already been done, a coherent national food safety strategy and concerted efforts by all stakeholders are needed to realize this vision. Cooperation of many government agencies with shared responsibility for food safety and public health will be essential.
