Growth rate, impact of smoking and management of incidentally found paranasal sinus osteomas.

OBJECTIVE: To build upon existing literature regarding growth rate of asymptomatic, incidentally found paranasal sinus (PNS) osteomas, evaluate potential factors associated with growth rate and present an argument for how to follow up. METHODS: At our institution, EPIC SlicerDicer was used to screen imaging studies using keyword 'osteoma' and included patients with at least 2 imaging studies 6 months apart that both demonstrated a PNS osteoma(s). Imaging studies with the largest time interval were selected. Non-PNS osteomas were excluded. RESULTS: 47 patients that fit this criterion with a median duration of interval imaging of 35.9 months. Growth rate was measured to be 0.39 mm/year in the cephalocaudal direction and 0.45 mm/year in the mediolateral direction, together averaging 0.42 mm/year. Increases in growth rate additionally did not appear to impact the likelihood of developing conditions including nasal polyposis or chronic sinusitis and symptoms such as sinus pressure, headache, postnasal drip, or congestion. Those with interval scans >36 months were found to have a slower growth rate than those with closer interval scans. Furthermore, former smokers and current smokers had significantly greater growth rates than nonsmokers. CONCLUSION: Given their slow growth rate, we conclude that select lesions likely do not require follow-up. If there is concern that growth could cause an obstructive complication, such as blocking the frontal outflow tract, we argue a single scan at one year is appropriate. If there is additional growth on this scan, surveillance scans up to 3 years could be performed to assess stability. Lastly, while there was a significant growth rate for smokers compared to non-smokers, the slow growth rate is unlikely to influence management.

Broadening placement opportunities for nursing students through an indirect supervision model.

BACKGROUND: Higher Education Institutions struggle to fill national deficits in student placement capacity, especially in social care and the voluntary sector. The Indirect Placement Supervision and Assessment Model and its holistic focus helps redress this deficit. METHODS: A Microsoft Forms survey was distributed to a self-selecting sample of 50 students, placement providers, and university staff, all of whom had been involved in indirect supervision as either an assessor, student, or supervisor. RESULTS: Three key themes emerged from the data collected; responses suggested that the model generated greater placement variety, increased placement capacity, and brought about reciprocal gains in the learner-supervisor matrix. CONCLUSION: The study's key implication for healthcare institutions pertains to a strong evidence base that the indirect supervision model provides an efficient means of broadening nursing placement variety and capacity alike.

Noninvasive Temperature Measurements in Tissue-Simulating Phantoms Using a Solid-State Near-Infrared Sensor.

The monitoring of body temperature is a recent addition to the plethora of parameters provided by wellness and fitness wearable devices. Current wearable temperature measurements are made at the skin surface, a measurement that is impacted by the ambient environment of the individual. The use of near-infrared spectroscopy provides the potential for a measurement below the epidermal layer of skin, thereby having the potential advantage of being more reflective of physiological conditions. The feasibility of noninvasive temperature measurements is demonstrated by using an in vitro model designed to mimic the near-infrared spectra of skin. A miniaturizable solid-state laser-diode-based near-infrared spectrometer was used to collect diffuse reflectance spectra for a set of seven tissue phantoms composed of different amounts of water, gelatin, and Intralipid. Temperatures were varied between 20-24 °C while collecting these spectra. Two types of partial least squares (PLS) calibration models were developed to evaluate the analytical utility of this approach. In both cases, the collected spectra were used without pre-processing and the number of latent variables was the only optimized parameter. The first approach involved splitting the whole dataset into separate calibration and prediction subsets for which a single optimized PLS model was developed. For this first case, the coefficient of determination (R2) is 0.95 and the standard error of prediction (SEP) is 0.22 °C for temperature predictions. The second strategy used a leave-one-phantom-out methodology that resulted in seven PLS models, each predicting the temperatures for all spectra in the held-out phantom. For this set of phantom-specific predicted temperatures, R2 and SEP values range from 0.67-0.99 and 0.19-0.65 °C, respectively. The stability and reproducibility of the sample-to-spectrometer interface are identified as major sources of spectral variance within and between phantoms. Overall, results from this in vitro study justify the development of future in vivo measurement technologies for applications as wearables for continuous, real-time monitoring of body temperature for both healthy and ill individuals.

Is Preoperative Chemoprophylaxis Safe for Venous Thromboembolism Prevention in Patients With Head and Neck Cancer?

OBJECTIVE: To assess the safety of preoperative chemoprophylaxis (PEC) in head and neck cancer (HNC) patients undergoing oncologic procedures. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic center. METHODS: HNC patients with Caprini risk score (CRS) ≥5 who underwent inpatient surgery ≥3 hours between 2015 and 2020 were included. Patients were divided into 2 cohorts, PEC and control, based on whether or not they received a single dose of low molecular weight heparin or unfractionated heparin prior to surgery. The primary endpoint was the 30-day rate of major bleeding events. RESULTS: A total of 539 patients were included; 427 patients received PEC prior to surgery. The rate of major bleeding was 6.7%. The PEC cohort was more likely to have received concurrent aspirin or ketorolac (225 of 427 patients vs 36 of 112 patients; P = .0002), greater duration of chemoprophylaxis (7.8 vs 5.0 days; P < .0001), have higher CRS (7.2 vs 6.6; P < .0001), longer operative times (596 vs 512 minutes; P < .0001), higher blood loss (265 vs 214 ml; P = .02), and higher bleeding rates when compared to the control (34 of 427 patients; P = .03). On multivariate analysis, only PEC was associated with bleeding (odds ratio, 8.74; 95% confidence interval, 1.15-66.5). The rate of VTE was 1.3% and was not significantly different between cohorts. CONCLUSION: PEC was associated with an increase in bleeding and did not result in lower rates of VTE in patients with HNC. This study highlights the need to determine the optimal regimen of chemoprophylaxis in this patient cohort.

Assessment of Survival Kinetics for Emergent Highly Pathogenic Clade 2.3.4.4 H5Nx Avian Influenza Viruses.

High pathogenicity avian influenza viruses (HPAIVs) cause high morbidity and mortality in poultry species. HPAIV prevalence means high numbers of infected wild birds could lead to spill over events for farmed poultry. How these pathogens survive in the environment is important for disease maintenance and potential dissemination. We evaluated the temperature-associated survival kinetics for five clade 2.3.4.4 H5Nx HPAIVs (UK field strains between 2014 and 2021) incubated at up to three temperatures for up to ten weeks. The selected temperatures represented northern European winter (4 °C) and summer (20 °C); and a southern European summer temperature (30 °C). For each clade 2.3.4.4 HPAIV, the time in days to reduce the viral infectivity by 90% at temperature T was established (DT), showing that a lower incubation temperature prolonged virus survival (stability), where DT ranged from days to weeks. The fastest loss of viral infectivity was observed at 30 °C. Extrapolation of the graphical DT plots to the x-axis intercept provided the corresponding time to extinction for viral decay. Statistical tests of the difference between the DT values and extinction times of each clade 2.3.4.4 strain at each temperature indicated that the majority displayed different survival kinetics from the other strains at 4 °C and 20 °C.

Outpatient Parenteral Antimicrobial Therapy in a Safety Net Hospital: Opportunities for Improvement.

Background: Outpatient parenteral antimicrobial therapy (OPAT) is a safe and cost-effective transitional care approach administered via different delivery models. No standards exist for appropriate OPAT program staffing. We examined outcomes of patients receiving OPAT via different care models to identify strategies to improve safety while reducing health care overuse. Methods: Retrospective demographic, clinical, and outcome data of patients discharged with OPAT were reviewed in 2 periods (April-June 2021 and January-March 2022; ie, when staffing changed) and stratified by care model: self-administered OPAT, health care OPAT, and skilled nursing facility OPAT. Results: Of 342 patients, 186 (54%) received OPAT in 2021 and 156 (46%) in 2022. Hospital length of stay rose from 12.4 days to 14.3 in 2022. In a Cox proportional hazards regression model, visits to the emergency department (ED) within 30 days of OPAT initiation (hazard ratio, 1.76; 95% CI, 1.13-2.73; P = .01) and readmissions (hazard ratio, 2.34; 95% CI, 1.22-4.49; P = .01) increased in 2022 vs 2021, corresponding to decreases in OPAT team staffing. Higher readmissions in the 2022 cohort were for reasons unrelated to OPAT (P = .01) while readmissions related to OPAT did not increase (P = .08). Conclusions: In a well-established OPAT program, greater health care utilization-length of stay, ED visits, and readmissions-were seen during periods of higher staff turnover and attrition. Rather than blunt metrics such as ED visits and readmissions, which are influenced by multiple factors besides OPAT, our findings suggest the need to develop OPAT-specific outcome measures as a quality assessment tool and to establish optimal OPAT program staffing ratios.

Inflammatory bowel disease-associated colorectal cancer negatively affects surgery outcomes and health care costs.

BACKGROUND: Inflammatory bowel disease may affect the pathogenesis and clinicopathologic course of colorectal cancer. We sought to characterize the impact of inflammatory bowel disease on outcomes after colectomy and/or proctectomy for a malignant indication. METHODS: Patients diagnosed with colorectal cancer as well as a pre-existing comorbid diagnosis of Crohn's disease or ulcerative colitis between 2018 and 2021 were identified from Medicare claims data. The postoperative textbook outcome was defined as the absence of complications, as well as no extended hospital stay, 90-day readmission, or mortality. Postdischarge disposition and expenditures were also examined. RESULTS: Among 191,684 patients with colorectal cancer, 4,770 (2.5%) had a pre-existing diagnosis of inflammatory bowel disease. Patients with inflammatory bowel disease-associated colorectal cancer were less likely to undergo surgical resection (no inflammatory bowel disease: 47.6% vs inflammatory bowel disease: 42.1%; P < .001). Among patients who did undergo colorectal surgery, individuals with inflammatory bowel disease were less likely to achieve a textbook outcome (odds ratio 0.64 [95% confidence interval 0.58-0.70]). In particular, patients with inflammatory bowel disease had higher odds of postoperative complications (odds ratio 1.24 [1.12-1.38]), extended hospital stay (odds ratio 1.41 [1.27-1.58]), and readmission within 90 days (odds ratio 1.56 [1.42-1.72]) (all P < .05). Patients with inflammatory bowel disease-associated colorectal cancer were less likely to be discharged to their home under independent care (odds ratio 0.77 [0.68-0.87]) and had 12.2% higher expenditures, which correlated with whether the patient had a postoperative textbook outcome. CONCLUSION: One in 40 patients with colorectal cancer had concomitant inflammatory bowel disease. Inflammatory bowel disease was associated with a lower probability of achieving ideal postoperative outcomes, higher postdischarge expenditure, as well as worse long-term survival after colorectal cancer resection.

Bayesian evaluation of meat juice ELISA for detecting Salmonella in slaughtered pigs without specifying a cut-off.

BACKGROUND: Consumption of pork and pork products is a major source of human infection with Salmonella. Salmonella is typically subclinical in pigs, making it difficult to identify infected pigs. Therefore, effective surveillance of Salmonella in pigs critically relies on good knowledge on how well the diagnostic tests used perform. A test that has been used in several countries for Salmonella monitoring is serological testing of meat juice using an ELISA (MJ ELISA) to detect antibodies against Salmonella. This MJ ELISA data could be used to estimate infection prevalence and trends. However, as the MJ ELISA output is a sample-to-positive (S/P) ratio, which is a continuous outcome rather than a binary (positive/negative) result, the interpretation of this data depends upon a chosen cut-off. AIM: To apply Bayesian latent class models (BLCMs) to estimate diagnostic accuracy of the MJ ELISA test values in the absence of a gold standard without needing to apply a cut-off. METHODS AND RESULTS: BLCMs were fitted to data from a UK abattoir survey carried out in 2006 in order to estimate the diagnostic accuracy of MJ ELISA with respect to the prevalence of active Salmonella infection. This survey consisted of a MJ ELISA applied in parallel with the bacteriological testing of caecal contents, carcass swabs and lymph nodes (n = 625). A BLCM was also fitted to the same data but with dichotomisation of the MJ ELISA results, in order to compare with the model using continuous outcomes. Estimates were obtained for sensitivity and specificity of the ELISA over a range of S/P values and for the bacteriological tests and were found to be similar between the models using continuous and dichotomous ELISA outcomes. CONCLUSION: The Bayesian method without specifying a cut-off does allow prevalence to be inferred without specifying a cut-off for the ELISA. The study results will be useful for estimating infection prevalence from serological surveillance data.

The undue influence of genetic information on senior medical students' treatment decisions.

BACKGROUND: Knowledge of the genetic basis of health conditions can influence how the public perceives their own and others' health. When there are known genetic associations for such conditions, genetic essentialist biases facilitate deterministic thinking and an over-emphasis of genetic causality. This study investigates the role that genetic essentialist biases play in medical decision-making. METHODS: Senior postgraduate medical students (N = 102) read a scenario in which a patient presents with gastroenterological symptoms. Half of the students were told that the patient tested positive for HLADQ2 - a gene implicated in, but not deterministic of, coeliac disease. The other half received no genetic information. Students were assessed on their recommendations for investigation and management using a multiple-choice questionnaire. Twenty-two of these students participated in a qualitative follow-up which used focus groups and semi-structured interviews to explore the reasoning behind students' responses. RESULTS: Management recommendations differed between the two groups, with those receiving genetic information more likely to recommend a gluten free diet. Recommendations for further investigation did not differ significantly between groups. Interviews suggested that these findings arose despite the students' good understanding of the common non-deterministic nature of genes, such as HLADQ2. CONCLUSION: Differences in management recommendations suggest that the inclusion of genetic information unduly biased students towards a premature diagnosis of a serious health condition, coeliac disease. Follow-up interviews introduced the possibility that observed manipulation-based differences may have been based on anticipated expectations of examiners, rather than perceived future clinical practice. Based on the present results it is unclear whether intentional exam-taking strategies fully account for medical students' decisions, or if they contribute in addition to the activation of genetic essentialist biases. Further research in clinical settings may ascertain whether genetic essentialist biases would truly influence medical student and doctors within their clinical practice environment.

Clinician perspectives on voluntary assisted dying and willingness to be involved: a multisite, cross-sectional survey during implementation in New South Wales, Australia.

BACKGROUND: In the context of nationwide law reform, New South Wales (NSW) became the last state in Australia to legalise voluntary assisted dying (VAD) - commencing 28 November 2023. Clinicians have divergent views regarding VAD, with varying levels of understanding, support, and willingness to be involved, and these may have a significant impact on the successful implementation. AIMS: To understand levels of support, understanding and willingness to be involved in VAD among clinical staff across NSW during implementation of VAD. METHODS: A multisite, cross-sectional online survey of clinicians across four local health districts, assessing relevant demographics, awareness of and support for VAD legislation and willingness to be involved in different levels of VAD-related clinical activities. RESULTS: A total of 3010 clinical staff completed the survey. A majority of participants were aware of VAD legislation in NSW (86.35%) and supportive of it (76%), with nursing and allied health clinicians significantly more likely than medical specialists to express support. Among medical specialists, support was statistically more likely in those who did not care for patients at the end of life and those with limited knowledge of the legislation. Willingness of medical specialists to perform key roles was significantly lower, with 41.49% willing to act in coordinating or consulting roles, and only 23.21% as administering practitioners. CONCLUSIONS: The majority of clinical staff surveyed across NSW supported VAD legislation. While many eligible clinicians were reluctant to be actively involved, sufficient numbers appear willing to provide VAD services, indicating that successful implementation should be possible.

Modelling flock heterogeneity in the transmission of peste des petits ruminants virus and its impact on the effectiveness of vaccination for eradication.

Peste des petits ruminants (PPR) is an acute infectious disease of small ruminants targeted for global eradication by 2030. The Global Strategy for Control and Eradication (GSCE) recommends mass vaccination targeting 70% coverage of small ruminant populations in PPR-endemic regions. These small ruminant populations are diverse with heterogeneous mixing patterns that may influence PPR virus (PPRV) transmission dynamics. This paper evaluates the impact of heterogeneous mixing on (i) PPRV transmission and (ii) the likelihood of different vaccination strategies achieving PPRV elimination, including the GSCE recommended strategy. We develop models simulating heterogeneous transmission between hosts, including a metapopulation model of PPRV transmission between villages in lowland Ethiopia fitted to serological data. Our results demonstrate that although heterogeneous mixing of small ruminant populations increases the instability of PPRV transmission-increasing the chance of fadeout in the absence of intervention-a vaccination coverage of 70% may be insufficient to achieve elimination if high-risk populations are not targeted. Transmission may persist despite very high vaccination coverage (>90% small ruminants) if vaccination is biased towards more accessible but lower-risk populations such as sedentary small ruminant flocks. These results highlight the importance of characterizing small ruminant mobility patterns and identifying high-risk populations for vaccination and support a move towards targeted, risk-based vaccination programmes in the next phase of the PPRV eradication programme. Our modelling approach also illustrates a general framework for incorporating heterogeneous mixing patterns into models of directly transmitted infectious diseases where detailed contact data are limited. This study improves understanding of PPRV transmission and elimination in heterogeneous small ruminant populations and should be used to inform and optimize the design of PPRV vaccination programmes.

Executive Summary: Guidelines and Recommendations for Laboratory Analysis in the Diagnosis and Management of Diabetes Mellitus.

BACKGROUND: Numerous laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. An expert committee compiled evidence-based recommendations for laboratory analysis in patients with diabetes. The overall quality of the evidence and the strength of the recommendations were evaluated. The draft consensus recommendations were evaluated by invited reviewers and presented for public comment. Suggestions were incorporated as deemed appropriate by the authors (see Acknowledgments in the full version of the guideline). The guidelines were reviewed by the Evidence Based Laboratory Medicine Committee and the Board of Directors of the American Association of Clinical Chemistry and by the Professional Practice Committee of the American Diabetes Association. CONTENT: Diabetes can be diagnosed by demonstrating increased concentrations of glucose in venous plasma or increased hemoglobin A1c (Hb A1c) in the blood. Glycemic control is monitored by the patients measuring their own blood glucose with meters and/or with continuous interstitial glucose monitoring devices and also by laboratory analysis of Hb A1c. The potential roles of noninvasive glucose monitoring; genetic testing; and measurement of ketones, autoantibodies, urine albumin, insulin, proinsulin, and C-peptide are addressed. SUMMARY: The guidelines provide specific recommendations based on published data or derived from expert consensus. Several analytes are found to have minimal clinical value at the present time, and measurement of them is not recommended.

Cumulative Sum Chart as Complement to Objective Assessment of Graduating Surgical Resident Competency: An Exploratory Study.

BACKGROUND: Rater-based assessment and objective assessment play an important role in evaluating residents' clinical competencies. We hypothesize that a cumulative sum (CUSUM) chart of operative time is a complement to the assessment of chief general surgery residents' competencies with ACGME Milestones, aiding residency programs' determination of graduating residents' practice readiness. STUDY DESIGN: We extracted ACGME Milestone evaluations of performance of operations and procedures (POP) and 3 objective metrics (operative time, case type, and case complexity) from 3 procedures (cholecystectomy, colectomy, and inguinal hernia) performed by 3 cohorts of residents (N = 15) during their PGY4-5. CUSUM charts were computed for each resident on each procedure type. A learning plateau was defined as at least 4 cases consistently locating around the centerline (target performance) at the end of a CUSUM chart with minimal deviations (range 0 to 1). RESULTS: All residents reached the ACGME graduation targets for the overall POP by the end of chief year. A total of 2,446 cases were included (cholecystectomy N = 1234, colectomy N = 507, and inguinal hernia N = 705), and 3 CUSUM chart patterns emerged: skewed distribution, bimodal distribution, and peaks and valleys distribution. Analysis of CUSUM charts revealed surgery residents' development processes in the operating room towards a learning plateau vary, and only 46.7% residents reach a learning plateau in all 3 procedures upon graduation. CONCLUSIONS: CUSUM charts of operative time complement the ACGME Milestones evaluations. The use of both may enable residency programs to holistically determine graduating residents' practice readiness and provide recommendations for their upcoming career/practice transition.

Algorithmic Identification of Patients With Aspirin-Exacerbated Respiratory Disease Using an Electronic Health Record.

OBJECTIVE: To determine whether an electronic health record (EHR) system can be used to identify cases of aspirin-exacerbated respiratory disease (AERD) in an area outside of a regional referral center with low rates of aspirin desensitization therapy. STUDY DESIGN: Retrospective chart review single academic tertiary care hospital. SETTING: Single-site academic tertiary care hospital. METHODS: Using Epic's SlicerDicer function, an algorithm was created and applied to all patient charts from 2013 to 2021. The algorithm was as follows: "Allergy/Contraindication to NSAIDs OR aspirin" AND "Diagnosis of Nasal polyp AND "Diagnosis of Asthma." Clinical data including demographics, NSAID reaction, and specialist involvement was collected. RESULTS: A total of 54 potential cases of AERD were identified. Thirty-two were determined to have AERD after chart review, yet 12 of these patients (37.5%) had no mention of AERD within the chart. The 54 patients were stratified into 2 cohorts based on reaction to NSAIDs: respiratory (n = 29) or unspecified (n = 25). Of the patients in the respiratory reaction group, 26 were found to have clinical AERD, demonstrating a positive predictive values (PPV) of 89.7%. The overall PPV was 59.3%. Those with a respiratory reaction to NSAIDS listed in the EHR were more likely to have clinical AERD (odds ratio 27.44; confidence interval 6.08-123.85; p < 0.0001). Only 2 patients (6.3%) underwent aspirin desensitization. CONCLUSION: AERD remains under-diagnosed in the study population. The informatics algorithm presented here has a high positive predictive value for identifying clinical AERD patients in a geographical area with low rates of aspirin desensitization and may aid in identifying candidates for expanded treatment options.

The Ethics of Overlapping Relationships in Rural and Remote Healthcare. A Narrative Review.

It is presently unclear whether a distinct "rural ethics" of navigating professional boundaries exists, and if so, what theoretical approaches may assist practitioners to manage overlapping relationships. To be effective clinicians while concurrently partaking in community life, practitioners must develop and maintain safe, ethical, and sustainable therapeutic relationships in rural and remote healthcare. A narrative review was conducted identifying a significant body of qualitative and theoretical literature which explores the pervasiveness of dual relationships for practitioners working in rural and remote healthcare. Rather than viewing dual relationships as ethically unacceptable, much contemporary work focusses on the lived experiences of healthcare workers and explores what approaches may be available that both protect the therapeutic relationship while recognizing the unique nature of rural and remote healthcare practice. We conclude that practitioners must have a means of operating within a contextually informed ethics of professional boundaries. Drawing on pre-existing work, one schema is proposed that could form the basis for further engagement through interactive teaching sessions, professional development, mentoring, or guidelines.
