- Abstract
A vertical co?product technology simultaneously produces multiple outputs that differ along a rankable quality metric. Co?product manufacturers often sell products through a distributor. We examine a setting in which a manufacturer sells vertically differentiated co?products through a self?interested distributor to quality?sensitive end customers. The manufacturer determines its production, product line design, and wholesale prices. The distributor determines its purchase quantities and retail prices. In traditional product?line design, products can be produced independently of each other and higher?quality products have higher production costs. This literature established that the length of the product line (i.e., difference between highest and lowest qualities) is greater in an indirect channel than in a direct channel. By contrast, co?products cannot be produced independently of each other. Among other findings, we establish that this interdependency causes the opposite channel effect: for co?products, the length of the product line is smaller in an indirect channel than in a direct channel. Additionally, we show that there exists a theoretical contract, combining revenue sharing and reverse slotting fees, that eliminates the indirect channel distortions in both product line design and output quantities.

- Abstract
The odd-odd N = Z nuclide, 78Y has been produced in the 40Ca(40Ca,pn) reaction at 125 MeV. Recoiling fragments separated by their AIQ values were implanted onto the tape of a moving tape collector and transported to a shielded position between two plastic β detectors and two Ge γ-ray detectors where β-γ coincidences were recorded as a function of time. γ rays with energies of 279 (100%), 504 (90%), and 713 (40%) keV, previously identified as yrast transitions in daughter 78Sr, were observed and found to decay with a half-life of 5.8 (6) s. From the relative intensities of the γ-rays, a spin and parity of 5+ and T = 0 are assigned to the parent state in 78Y undergoing β decay. A production cross section of 4±1 μb has been determined for 78Y by comparison of the counting rates with those of other reaction products with known cross sections. An upper limit of 500 keV can be set for the energy of this level relative to a possible highly deformed T = 1 0+ ground state. From this limit, it can be inferred that T = 1 pn pairing is considerably quenched relative to such pairing in adjacent odd-odd N = Z 7‡Rb. Two-quasiparticle rotor model calculations have been used to account for the structure of 78Y and adjacent nuclides.

- Abstract
Objective . Neonatal hypothermia is a worldwide health burden with an incidence ranging from 32% to 85% in hospitals and 11% to 92% in homebirths. It is prevalent in Nepal and associated with increased morbidity and mortality. The study objective was to identify key practice standards of newborn thermal management in Nepal. Methods . Our subjects included 6 lead newborn physicians from major birthing centers in Kathmandu. A modified Delphi process was used to identify the top 5 key practice standards for newborn thermoregulation in the hospital, health post, and home, compiled from 14 World Health Organization recommended practices. Results . There was consensus in all ranked practices except using radiant heat sources in the hospital and performing Kangaroo Mother Care in the homebirths. Comments conveyed that interventions during the immediate delivery phase were most impactful and feasible. Conclusion . Nepali physicians prioritized thermoregulatory practices during the immediate resuscitation period over the post-resuscitation period., Competing 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) 2024.)

- Abstract
As detailed in its flagship report, Genome UK, the UK government recognises the vital role that broad public engagement across whole populations plays in the field of genomics. However, there is limited evidence about how to do this at scale. Most public audiences do not feel actively connected to science, are oftenunsure of the relevance to their lives and rarely talk to their family and friends about; we term this dis-connection a 'disengaged public audience'. We use a narrative review to explore: (i) UK attitudes towards genetics and genomics and what may influence reluctance to engage with these topics; (ii) innovative public engagement approaches that have been used to bring diverse public audiences into conversations about the technology. Whilst we have found some novel engagement methods that have used participatory arts, film, social media and deliberative methods, there is no clear agreement on best practice. We did not find a consistently used, evidence-based strategy for delivering public engagement about genomics across diverse and broad populations, nor a specific method that is known to encourage engagement from groups that have historically felt (in terms of perception) and been (in reality) excluded from genomic research. We argue there is a need for well-defined, tailor-made engagement strategies that clearly articulate the audience, the purpose and the proposed impact of the engagement intervention. This needs to be coupled with robust evaluation frameworks to build the evidence-base for population-level engagement strategies., Competing Interests: No competing interests were disclosed., (Copyright: © 2023 Middleton A et al.)

- Abstract
The way we "talk" about genetics plays a vital role in whether public audiences feel at ease in having conversations about it. Our research explored whether there was any difference between "what we say" and "what people hear" when providing information about genetics to community groups who are known to be missing from genomics datasets. We conducted 16 focus groups with 100 members of the British public who had limited familiarity with genomics and self-identified as belonging to communities with Black African, Black Caribbean, and Pakistani ancestry as well as people of various ancestral heritage who came from disadvantaged socio-economic backgrounds. Participants were presented with spoken messages explaining genomics and their responses to these were analyzed. Results indicated that starting conversations that framed genomics through its potential benefits were met with cynicism and skepticism. Participants cited historical and present injustices as reasons for this as well as mistrust of private companies and the government. Instead, more productive conversations led with an acknowledgment that some people have questions-and valid concerns-about genomics, before introducing any of the details about the science. To diversify genomic datasets, we need to linguistically meet public audiences where they are at . Our research has demonstrated that everyday talk about genomics, used by researchers and clinicians alike, is received differently than it is likely intended. We may inadvertently be further disengaging the very audiences that diversity programs aim to reach., Competing Interests: The authors declare no competing interests., (© 2023 The Author(s).)

- Abstract
Objective To examine antibiotic use in long-term care residents at a VA skilled nursing facility. Design Quality improvement project. Setting Long-term care residents admitted to the Community Living Center of a Midwestern VA medical center. Patients Inclusion criteria were long-term care residents admitted to the VA skilled nursing facility who were prescribed an oral (including via percutaneous endoscopic gastrostomy tube) antibiotic from January 1, 2018, to December 31, 2018. Residents were excluded if they were admitted for hospice care, rehabilitation, or short-term skilled nursing. Residents were also excluded if they were on intravenous or topical antibiotics. Results Fifty-six unique antibiotic courses consisting of 13 different antibiotics were evaluated. Median days of therapy per 1,000 resident days was 39.7 overall, for quarter 1 was 51, quarter 2 was 42, quarter 3 was 49.3, and quarter 4 was 17.5. Average antibiotic days of therapy was 7.6 days. Fluoroquinolones comprised 26.8% of the courses, followed by beta-lactamase inhibitors at 25%. Of the 56 courses, 85.7% were found to have appropriate dose/frequency, while 73.2% had appropriate duration. No reports of Clostridioides difficile infection were noted. Thirty-one antibiotic courses had cultures obtained, of which 29 did not deescalate therapy. Of these, 5 (17.2%) were indicated for de-escalation. Conclusion Antibiotic use in this skilled nursing facility have opportunities for intervention, including reducing fluoroquinolone use, optimizing de-escalation, and shortening days of therapy. The implementation of an antimicrobial stewardship monitoring program within the long-term care setting could assist in maximizing therapy while reducing antibiotic exposure.

- Abstract
Arsenic (As) is a common contaminant in soils, and analysis of soils by inductively coupled plasma-mass spectrometry (ICP-MS) is often used to detect As in soil extracts. Internal standards (ISs) are part of ICP-MS analyses to enhance precision and accuracy by compensating for instrument variability; however, an improper choice of IS can result in negative analytical bias. The goal of this study was to develop a protocol for evaluating ISs commonly used in ICP-MS. Three soils of varying clay content and total As were extracted with a dilute electrolyte [0.005 mol L
-1 Mg(NO3 )2 ] and an acid digest. Arsenic concentrations were quantified by ICP-MS using typical ISs:6 Li,45 Sc,69 Ga,89 Y,103 Rh,115 In,159 Tb, and209 Bi. Standard addition was used as a benchmark for As quantification. The most consistent IS was115 In. Elevated, naturally occurring concentrations were detected for several of the ISs, particularly in the total digests, emphasizing the necessity for screening soils prior to analysis., (© 2022 The Authors.

- Abstract
The consolidation of information technology (IT) teams from individual facilities to an enterprise-wide reporting structure and the transition of IT staff from operating within a diagnostic imaging department, such as Radiology, to an enterprise IT group is common. The plan to optimize this workforce can have undesirable and unintended consequences, if not done correctly. For those organizations seeking to optimize their workforce to deliver the best possible IT services, including to areas that produce and use medical imaging, this can be an exercise of balancing specialized knowledge and centralized staffing capacity planning. Successfully blending staff that have developed through careers in either general or imaging IT areas into a single team structure requires an understanding of their traditional attitudes, priorities, and skill sets. This paper explores the historic similarities and differences in the skill sets and work cultures between imaging and Enterprise IT, and how to use both to deliver the best outcomes., (© 2021.

- Abstract
OBJECTIVE: To analyze medication interventions prior to and following implementation of the Pharmacy Medication Related Falls Risk Assessment consult service in an older adult population. DESIGN: Retrospective chart review. SETTING: This study involved patients admitted to the Cincinnati Veterans Affairs Medical Center's (VAMC) Community Living Center (CLC), an institutional practice setting. PATIENTS, PARTICIPANTS: Any patient who experienced a fall while admitted to the CLC during fiscal years 2013 or 2018 was considered for inclusion. Patients were excluded if falls were not evaluated by a provider, the patient expired within 10 days after falling, or falls in fiscal year 2018 that did not have a pharmacy consult placed. Fifty falls from each fiscal year were selected. MAIN OUTCOME MEASURES: The primary endpoint encompassed the number of pharmacy medication interventions made within 10 days postfall, with a secondary endpoint evaluating subsequent falls within 30 days of initial event. RESULTS: Following consult implementation, a larger number of pharmacist recommendations (40 vs. 123) and subsequent interventions (accepted recommendations) within ten days postfall (12 vs. 49) were completed. There were 14 subsequent falls within 30 days of the initial event for both fiscal years. A larger percentage of falls and patients experiencing falls from each fiscal year did not receive previous medication interventions. CONCLUSION: Consult implementation increased the number of pharmacist recommendations and subsequent interventions for patients within ten days postfall, reducing the risk of adverse effects, drug-drug interactions, subsequent falls, and polypharmacy.

- Abstract
OBJECTIVE Stereotactic radiosurgery (SRS) with or without whole-brain radiotherapy can be used to achieve local control (> 90%) for small brain metastases after resection. However, many brain metastases are unsuitable for SRS because of their size or previous treatment, and whole-brain radiotherapy is associated with significant neurocognitive morbidity. The purpose of this study was to investigate the efficacy and toxicity of surgery and iodine-125 (
125 I) brachytherapy for brain metastases. METHODS A total of 95 consecutive patients treated for 105 brain metastases at a single institution between September 1997 and July 2013 were identified for this analysis retrospectively. Each patient underwent MRI followed by craniotomy with resection of metastasis and placement of125 I sources as permanent implants. The patients were followed with serial surveillance MRIs. The relationships among local control, overall survival, and necrosis were estimated by using the Kaplan-Meier method and compared with results of log-rank tests and multivariate regression models. RESULTS The median age at surgery was 59 years (range 29.9-81.6 years), 53% of the lesions had been treated previously, and the median preoperative metastasis volume was 13.5 cm3 (range 0.21-76.2 cm3 ). Gross-total resection was achieved in 81% of the cases. The median number of125 I sources implanted per cavity was 28 (range 4-93), and the median activity was 0.73 mCi (range 0.34-1.3 mCi) per source. A total of 476 brain MRIs were analyzed (median MRIs per patient 3; range 0-22). Metastasis size was the strongest predictor of cavity volume and shrinkage (p < 0.0001). Multivariable regression modeling failed to predict the likelihood of local progression or necrosis according to metastasis volume, cavity volume, or the rate of cavity remodeling regardless of source activity or previous SRS. The median clinical follow-up time in living patients was 14.4 months (range 0.02-13.6 years), and crude local control was 90%. Median overall survival extended from 2.1 months in the shortest quartile to 62.3 months in the longest quartile (p < 0.0001). The overall risk of necrosis was 15% and increased significantly for lesions with a history of previous SRS (p < 0.05). CONCLUSIONS Therapeutic options for patients with large or recurrent brain metastases are limited. Data from this study suggest that resection with permanent125 I brachytherapy is an effective strategy for achieving local control of brain metastasis. Although metastasis volume significantly influences resection cavity size and remodeling, volumetric parameters do not seem to influence local control or necrosis. With careful patient selection, this treatment regimen is associated with minimal toxicity and can result in long-term survival for some patients. ▪ CLASSIFICATION OF EVIDENCE Type of question: therapeutic; study design: retrospective case series; evidence: Class IV.- Published

- Abstract
Pediatric embryonal brain tumor patients treated with craniospinal irradiation (CSI) are at risk for adverse effects, with greater severity in younger patients. Here we compare outcomes of CSI vs. high-dose chemotherapy (HD), stem cell transplant (SCT) and delayed CSI in newly diagnosed patients. Two hundred one consecutive patients treated for medulloblastoma (72 %), supratentorial primitive neuroectodermal tumor (sPNET; 18 %) or pineoblastoma (10 %) at two institutions between 1988 and 2014 were retrospectively identified. Progression free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared by log-rank tests. Adjuvant CSI regimens were used for 56 % of patients (upfront-CSI), and HD/SCT regimens were used in 32 % of patients. HD/SCT patients were significantly younger than those receiving upfront-CSI (2.9 vs. 7.8 years; P < 0.0001). There were no differences in metastases, extent of resection, or CSI dose between upfront-CSI and HD/SCT patients, but median follow-up was shorter in the HD/SCT group (6.2 vs. 3.9 years; P = 0.007). There were no significant outcome differences between upfront-CSI and HD/SCT patients who received CSI as a prophylaxis or following relapse (OS 66 % vs. 61 %, P = 0.13; PFS 67 % vs. 62 %, P = 0.12). Outcomes were equivalent when restricting analyses to HD/SCT patients who received prophylactic CSI prior to relapse (OS 66 % vs. 65 %, P = 0.5; PFS 67 % vs. 74 %, P = 0.8). At last follow-up, 48 % of HD/SCT patients had received neither definitive nor salvage radiotherapy. In this retrospective cohort, outcomes with adjuvant HD/SCT followed by delayed CSI are comparable to upfront-CSI for carefully surveyed pediatric embryonal brain tumor patients. Future prospective studies are required to validate this finding, and also to assess the impact of delayed CSI on neurocognitive outcomes.

- Abstract
Purpose: High-dose-rate (HDR) brachytherapy alone is an effective treatment option for patients with early-stage prostate cancer. The purpose of this study was to quantify patient-reported short- and long-term toxicity and quality of life (QOL) after HDR monotherapy., Methods and Materials: Thirty-nine consecutive men between May 2001 and January 2012 were identified for this analysis. All patients underwent definitive HDR monotherapy for favorable prostate cancer to a total dose of 3150 cGy in three fractions, 3800 cGy in four fractions, or 3850 in five fractions. Patient-reported genitourinary function was assessed before HDR, during an acute period after treatment (within 90 days of HDR), and on long-term followup using the American Urological Association International Prostate Symptom Score, a urinary QOL Likert questionnaire, and the Sexual Health Inventory for Men questionnaire. Regression analyses were performed using the ordinary least squares method., Results: With median followup of 57 months, biochemical progression-free survival was 100%. There were no grade ≥3 toxicities. Dose to the urethra and bladder, as well as prostate size and intraprostatic urethra length were predictive for short-term changes in QOL. Advanced patient age was predictive for worse sexual function on both acute and long-term followup., Conclusions: Toxicity after HDR monotherapy for prostate cancer is acceptable. Patients with larger prostates, longer intraprostatic urethras, and greater doses to the bladder and urethra may experience worse acute urinary QOL. Older patients may experience greater impairment in sexual function in the short and long terms., (Copyright © 2015 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.)
