Published: September 2024

Traditional anatomical preparations as they are often found in university collections are both historical treasure and moral responsibility of the hosting institutions. These remains not only represent the tradition and history of anatomical science and education, but above all are the remains of human beings and thus should be treated with dignity. While the discussion on public display of historical human remains is ongoing, the responsibility to keep them in an optimal state of preservation is not in question. However, most time-honored anatomical collections do or did not have the financial and/or technical capacity to keep these high standards, underlining the need for exchange of technical know-how between anatomical institutes and the support of restoration/conservation professionals. Here, we present a state-of-the-art conservation and restoration of a fetal natural skeleton from the early twentieth century along with the professional documentation of restoration-measures. Therefore, we used modern photo- and video documentation, including photogrammetry, as well as UV- and x-ray-examinations to record historical and new restoration procedures. We carried out measures to reconstitute the structural stability of the skeleton. Moreover, we replaced lost parts of the left foot skeleton, and critically discuss the legitimacy of body part replacement in historical specimens. We are convinced, that similar cases of insufficiently preserved specimens can be found in most anatomical collections. Therefore, this article is not only intended to document the state-of-the-art conservation and restoration of a natural skeleton, but also serve as an inspiration for similar campaigns in other institutions in the future.
Impact of a suicide prevention learning module for firearm training courses in Louisiana
Authors: Houtsma Claire , Reyes Lauren , MacWilliams Katherine , True Gala
Published: September 2024

Background

Firearm suicide is a leading cause of death in the United States. Suicide prevention experts have advocated for upstream interventions that can be implemented prior to the development of suicidal thoughts, particularly those that focus on lethal means safety (LMS; e.g., increasing secure firearm storage). To reach firearm owners with LMS messaging, researchers have developed suicide prevention training content which can be incorporated into firearm training courses. However, no study to date has evaluated impact of such training on firearm course students’ subsequent knowledge, attitudes, and openness related to secure firearm storage. Thus, the current study sought to examine both the feasibility and acceptability of a LMS-focused suicide prevention training module among firearm course students, as well as the impact of this module on students’ secure firearm storage-related knowledge, attitudes, and openness.

Methods

Firearm instructors (N = 6) and students in firearm classes (N = 83) were recruited to participate. Students were invited to complete voluntary, anonymous pre- and post-surveys during courses they attended that were led by these instructors. Instructors and students were also invited to complete a brief qualitative interview.

Results

Results indicated that firearm instructors and students in firearm courses found the module feasible and acceptable. Additionally, students’ knowledge about the relationship between firearms and suicide, openness to changing firearm storage practices, and endorsement of the importance of discussing firearms and suicide with fellow firearm owners, as well as willingness and confidence to do so, all significantly increased after viewing the module.

Conclusions

These findings provide strong support for the use of such culturally competent LMS messaging as upstream suicide prevention in settings such as concealed carry courses.
Nominal and achieved stromal ablation depth after myopic transepithelial photorefractive keratectomy: implications for residual stromal thickness calculation
Authors: Feng Yue , Nitter Tore Arnstein , Liu Xu , Stojanovic Aleksandar
Published: September 2024

Background

The primary objective of this investigation was to compare the nominal central ablation depth with the achieved central corneal stromal ablation depth after StreamLight transepithelial photorefractive keratectomy (tPRK) for myopia with WaveLight® laser by Alcon Laboratories, TX, USA.

Methods

This ambispective study encompassed a retrospective analysis of 40 eyes who underwent treatment for myopia and astigmatism, followed by a prospective examination conducted 6–9 months postoperatively. Pre- and postoperative Avanti spectral-domain optical coherence tomography (SD-OCT; Optovue Inc., CA, USA) provided stromal and epithelial thickness maps. The difference between pre- and postoperative central stromal thicknesses at the corneal vertex was used to calculate the achieved stromal thickness ablation depth. This value was then compared with the corresponding central nominal depth on the laser ablation planning map.

Results

A total of 40 eyes (OD/OS:18/22) of 40 patients (31.4 ± 9.2 years) were available for evaluation. The mean treated spherical equivalent was − 2.98 ± 1.46 D. The mean nominal and achieved central stromal ablation depths were 51.22 µm and 59.67 μm, respectively, showing a mean stromal excessive ablation of 16.50%. The mean pre- and postoperative central epithelial thicknesses were 53.74 μm and 59.31 μm, respectively, showing a mean postoperative thickness increase of 10.46%. This increase in the epithelial thickness rendered the mean postoperative pachymetry reduction to 54.11 μm, only 2.33% greater than the mean nominal ablation depth.

Conclusions

The study revealed a central stromal ablation 16.50% greater than the nominal ablation depth. This excessive stromal removal was largely compensated for by the increase in epithelial thickness, resulting in a mean difference between the nominal ablation depth and the achieved central corneal pachymetry reduction of only 2.33%. This significant excessive central stromal ablation must be taken into consideration in the calculation of the residual stromal thickness.
Arachnoid Cysts in Athletes with Sports-Related Concussion: A Case Series and Literature Review
Authors: Stevens Andrew R. , Yakoub Kamal M. , Davies David J. , Belli Antonio , O’Halloran Philip J.
Published: September 2024

Background

Arachnoid cysts (AC) are associated with a risk of rupture or haemorrhage following head impact and pose a potential predisposing factor for significant complications of sport-related concussion. Despite a recognised association between ACs and intracranial haemorrhage/cyst rupture, the risk profile of participating in contact sports with AC is not well defined. We report a retrospective case series of players presenting to the Birmingham Sports Concussion Clinic between 2017 and 2023 and underwent MRI head, with a comprehensive review of the prior literature.

Results

432 athletes underwent MRI of which 11 were identified to have AC (middle fossa n = 8; posterior fossa n = 2, intraventricular n = 1). Average maximal diameter was 4.1 ± 1.2 cm. 64% had a protracted recovery (≥ 3 months). 9% experienced an AC specific complication (cyst rupture, complete neurological recovery, maximal diameter 6.5 cm, Galassi II, 4 previous concussions). 91% of patients (mean maximal diameter 3.9 ± 1.0 cm) experienced no complications despite multiple previous accumulated sports-related concussions (mean 3.3, range 1–9). Case studies from the literature are summarised (n = 63), with 98% reporting complications, none of which resulted in adverse or unfavourable neurological outcomes. Across prospective and retrospective cohort studies, 1.5% had a structural injury, and (where outcome was reported) all had a favourable outcome.

Conclusions

AC is an incidental finding in athletes, with the majority in our cohort having sustained serial concussions without AC complication. The single complication within this cohort occurred in the largest AC, and AC size is proposed as a tentative factor associated with increased risk of contact sports participation. Complications of AC appear to be a rare occurrence. This case series and review has not identified evidence to suggest that participation in sports with AC is of significant risk, though individualised assessment and discussion of the potential risks of contact sports participation should be offered.
From CFOs to crypto: exploratory study unraveling factors in corporate adoption
Authors: Campino José , Rodrigues Bruna
Published: September 2024

Cryptocurrency adoption has gained significant attention across various fields owing to its disruptive potential and associated challenges. However, companies' adoption of cryptocurrencies remains relatively low. This study aims to comprehensively examine the factors influencing cryptocurrency adoption, their interrelationships, and their relative importance. To achieve this objective, we employ a Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach coupled with network analysis tools. By adopting a practical approach rather than a purely theoretical one, our unique contribution lies in the valuable insights derived from experienced Chief Financial Officers (CFOs) of various companies with experience in both traditional finance and cryptocurrencies. Furthermore, the unique blend of analytical rigor and industry expertise supports the study's relevance, offering nuanced insights that are not only academically robust but also immediately applicable in the corporate landscape. Our findings highlight the paramount importance of safety in transactions and trust in the chosen platform for companies considering cryptocurrency adoption. Additionally, criteria such as faster transactions without geographical limitations, lower transaction fees, seamless integration with existing systems, and potential cost savings are identified as crucial drivers. Both the DEMATEL approach and network analysis reveal strong interconnections among the criteria, emphasizing their interdependence and, notably, their reliance on transactional safety. Furthermore, our causes and effects analysis indicates that CFOs perceive company-led cryptocurrency adoption to positively impact the broader cryptocurrency market.
A review of methods for the analysis of diagnostic tests performed in sequence
Authors: Fanshawe Thomas R. , Nicholson Brian D. , Perera Rafael , Oke Jason L.
Published: September 2024

Background

Many clinical pathways for the diagnosis of disease are based on diagnostic tests that are performed in sequence. The performance of the full diagnostic sequence is dictated by the diagnostic performance of each test in the sequence as well as the conditional dependence between them, given true disease status. Resulting estimates of performance, such as the sensitivity and specificity of the test sequence, are key parameters in health-economic evaluations. We conducted a methodological review of statistical methods for assessing the performance of diagnostic tests performed in sequence, with the aim of guiding data analysts towards classes of methods that may be suitable given the design and objectives of the testing sequence.

Methods

We searched PubMed, Scopus and Web of Science for relevant papers describing methodology for analysing sequences of diagnostic tests. Papers were classified by the characteristics of the method used, and these were used to group methods into themes. We illustrate some of the methods using data from a cohort study of repeat faecal immunochemical testing for colorectal cancer in symptomatic patients, to highlight the importance of allowing for conditional dependence in test sequences and adjustment for an imperfect reference standard.

Results

Five overall themes were identified, detailing methods for combining multiple tests in sequence, estimating conditional dependence, analysing sequences of diagnostic tests used for risk assessment, analysing test sequences in conjunction with an imperfect or incomplete reference standard, and meta-analysis of test sequences.

Conclusions

This methodological review can be used to help researchers identify suitable analytic methods for studies that use diagnostic tests performed in sequence.
Prevalence of household food insecurity and its association with food waste
Authors: Diana Rian , Martianto Drajat , Baliwati Yayuk F. , Sukandar Dadang , Hendriadi Agung
Published: September 2024

Background

Household food waste significantly contributes to overall food waste. While the relationship between food security and food waste has been extensively studied at the macro level, there is a need for research focusing on the quantitative association between food security and food waste at the household level in developing countries, particularly in Southeast Asia. This study aims to estimate the prevalence of household food insecurity and household food waste and to examine the association between household food security and food waste using direct measurements.

Subjects and methods

A total of 215 households in Bogor Regency, Indonesia, participated in this cross-sectional study. Food waste was measured using waste composition analysis and a 7-day diary. The Food Insecurity Experience Scale (FIES) questionnaire was used to assess household food security, while household income and the proportion of food expenditure were considered confounding factors. The association between food security and food waste was examined using Kendall tau-b and ordinal logistic regression.

Results

The prevalence of household food insecurity was 18.6%, and the average household food waste was 77 kg/cap/year. Cereals, tubers, and their derivatives (especially rice) and vegetables were major contributors to edible waste, while fruits dominated inedible waste. A negative association was observed between food waste and household food security (edible FW: p = 0.044, r = -0.110; total FW: p = 0.038, r = -0.114), suggesting that household food waste decreases as the severity of food insecurity increases. However, after adjusting for household income, the proportion of food expenditure, and the education levels of spouses, this association became statistically insignificant (p > 0.05).

Conclusion

There was no significant association between household food security status and food waste. Household income plays a significant role in determining the quantity of household food waste, as higher income is associated with increased food waste. Strategies to prevent and reduce food waste should focus on major contributors such as rice and vegetables, especially among families with higher food accessibility.

Published: September 2024

Background

Ligament tension balance is a major determinant for the success of total knee replacement (TKR). The present study aimed at determining the inter-rater and intra-rater reliability in performing ligament tension assessment using an imageless robotic-assisted TKR.

Methods

Twenty-four knees in 21 patients who received robotic-assisted TKR for end-stage varus osteoarthritis were examined. Three orthopedic specialists and six orthopedic trainees participated in the operations. Data from the ligament tension assessment were collected during the operations.

Results

For the inter-rater reliability, “extension medial” and “flexion medial” had excellent reliability whilst “extension lateral” and “flexion lateral” had good-to-excellent reliability. For the intra-rater reliability, “extension medial” showed excellent reliability, “extension lateral” and “flexion medial” showed good-to-excellent reliability, and “flexion lateral” showed moderate-to-excellent reliability.

Conclusions

Robotic-assisted technology provides a reliable solution to improve ligament tension assessment. All ligament tension assessments with the use of the technology could demonstrate at least good-to-excellent reliability except for the intra-rater reliability of “flexion lateral”.
T2 mapping post acute myocardial infarction: a novel technique in assessing myocardial edema
Authors: Elsaid Maha Mourad Mohyeldin , Mosaad Basant Mohamed Raief , Hassan Hend Galal Eldeen Mohamed Ali , Amin Youssef Mohamed Mohamed Fahmy , Ibrahim Ahmed Samir
Published: September 2024

Objective

Cardiovascular magnetic resonance (CMR) is considered the gold standard imaging modality for assessing myocardial infarction lesions, offering precise myocardial tissue characterization. Elevated transverse relaxation time (T2) serves as a specific indicator of increased myocardial water content, thus becoming a valuable index for myocardial edema. However, conventional T2-weighted CMR sequence exhibits several limitations, primarily providing qualitative information. In contrast, recently developed quantitative T2 mapping techniques overcome these limitations, enabling a more reliable assessment of myocardial edema. These techniques offer the advantage of diagnosing and monitoring myocardial injury without the necessity of contrast agents. Our study aims to add to a growing literature demonstrating the efficacy of quantitative T2 mapping technique to detect and quantify regions of myocardial edema post-myocardial infarction.

Result

Native T1 and T2 mapping accurately identified myocardial edema in all patients enrolled in the study. Notably, native T1 and T2 values exhibited a significant elevation in the infarcted myocardium compared to the remote myocardium (for T1: 1295.50 ± 87.65 vs. 1074.95 ± 92.86 ms, respectively; and for T2: 74.63 ± 6.51 vs. 52.53 ± 6.26 ms, respectively; p < 0.0001 for both). Microvascular obstruction was observed in 12 out of 20 patients, affecting one or more myocardial segments within the infarct areas. Among this subgroup, regions with a microvascular obstruction within the infarct zone displayed lower T1 and T2 values compared to areas of infarction without microvascular obstruction (for T1: 1115.05 ± 64.70 vs. 1295.50 ± 87.65 ms, respectively; and for T2: 53.65 ± 3.56 vs. 74.63 ± 6.51 ms, respectively; p < 0.0001 for both). Additionally, we provided reference values for myocardial T1 and T2 specific to our facility’s 1.5 Tesla CMR system, applicable to both infarct and remote myocardium.

Conclusion

Parametric T1 and T2 mapping techniques can detect and quantify myocardial edema resulting from myocardial infarction. The presence of microvascular obstruction that results from revascularization injury affects both T1 and T2 values. This information can be used and has broad clinical implications for diagnosis and guiding or monitoring the treatment of myocardial infarction.

Published: September 2024

Background

Addressing knowledge and concerns related to corticosteroid is essential to enhance patient care, promote optimal utilization, and minimize their potential side effects.

Methods

A cross-sectional study was conducted to assess knowledge and attitudes regarding corticosteroid use among healthcare providers (HCPs) in the United Arab Emirates using a validated questionnaire. Knowledge, attitudes, and fear items were described as frequency and percentages. Then, a total score was calculated; multilinear regression was used to see the effect of demographics on these scores.

Results

Among 129 HCPs, 100 had previously prescribed corticosteroids (77.5%), with intranasal spray being the most dispensed dosage form (89.0%). Respiratory diseases were the most reported indication for corticosteroid dispensing (93.0%). HCPs preferred corticosteroids for their ability to quickly relief of patients' symptoms (67.0%). About 60.0% identified increased appetite as a patient-reported side effect. The assessment of the HCPs' knowledge showed a median score of 10 out of 11 (IQR = 9–11). The median fear score was six out of 10 (IQR = 4–10), but they were significantly and conversely related to each other.

Conclusion

This study revealed that while HCPs in the UAE possess substantial knowledge regarding corticosteroid use, their concerns, particularly around side effects, indicate a need for further education. Addressing these concerns through targeted educational programs could enhance the safe and effective utilization of corticosteroids, ultimately improving patient care outcomes.

Authors: H.B. Sridevi , Fernandes Anisha Maria , D'souza Sanyo , B. Prashantha , Rao Pooja , Shenoy M Suchitra
Published: September 2024

Introduction Cancer and cytotoxic chemotherapy used for its treatment predispose to severe and often fatal infections. Prompt diagnosis and timely antibiotic therapy are crucial, with delays in therapy initiation having high mortality. Complete blood count (CBC) is an inexpensive, standardized, and preliminary investigation for the management and follow-up of cancer patients with diagnostic and prognostic value. Method We studied the types of infections associated with various cancers treated with chemotherapy, their etiologies and susceptibility patterns, and the hematological profile of these patients as predictors of infection. Results A total of 21 patients (12 solid and 9 hematological malignancies) presented with 31 febrile episodes. White Blood cell count (2079 cells/cu. mm), percentage of neutrophils (52.9%), absolute neutrophil (137.5 cells/cu. mm), and platelet count (1,77,507 cells/cu. mm) were significantly lower in the 11 patients with febrile neutropenia. The absolute lymphocyte count (412.7 cells/cu. mm) was reduced with a strikingly low Neutrophil-to-lymphocyte ratio (NLR) (6.07) in patients with neutropenia. Laboratory and radiological evidence were present in 14/15 episodes of hematological malignancies (p-0.218) whereas unexplained clinical sepsis was common in solid malignancies (p-0.0202). The majority of documented infections were bacterial, caused by gram-negative bacilli, often showing multi-drug resistance. Infectious etiologies were identified in 71.4% of the patients with febrile neutropenia for >5days. Bacterial infections developed within 2 days of neutropenia, whereas viral and fungal infections manifested in prolonged neutropenia. Multi-site infections and higher mortality rates were observed in patients with febrile neutropenia. (p<0.04) Conclusion Febrile neutropenia is a common complication among patients receiving chemotherapy for cancer, with an increased risk of morbidity and mortality. Early, rapid, and accurate diagnosis is key to prompt intervention. Hematological parameters such as Total Leukocyte count, platelet count, NLR, and Platelet-to-lymphocyte ratio are promising biomarkers in conjunction with morphological changes in neutrophils, thus proving that CBC and peripheral smears are simple, easily available, cost-effective, and highly dependable screening tools, especially in resource-poor settings.
Exoskeleton Training for Spinal Cord Injury Neuropathic Pain (ExSCIP): Protocol for a Phase 2 Feasibility Randomised Trial
Authors: White Conor , Doherty Orlaith , Smith Eimear , Blake Catherine , Finnerup Nanna Brix , Kirwan Nathan , Pollock Mark , Lennon Olive
Published: September 2024

Background Following Spinal Cord Injury (SCI), 53% of people develop neuropathic pain (NP). NP can be more debilitating than other consequences of SCI, and a persistent health issue. Pharmacotherapies are commonly recommended for NP management in SCI, although severe pain often remains refractory to these treatments in many sufferers. Furthermore, poor medication adherence exists, stemming from unacceptable side-effects and fear of dependency. Sensorimotor stimulation using active walking with robotic assistance has not been well studied in NP after SCI, despite convincing locomotor-based pre-clinical studies, identifying prevention and reversal of NP. Our primary aim is to assess the impact of exoskeleton-based walking on NP intensity and interference after SCI and examine feasibility outcomes for progression to a definitive trial. Methods This is a phase 2 single-blinded, randomised feasibility study. It will test the feasibility and acceptability of exoskeleton-based walking 3 times per week for 12 weeks (intervention), as a mechanistic-based intervention for NP after SCI. The comparator will be an equally dosed, blended relaxation programme devoid of motor imagery prompts. 40 participants with moderate-to-severe NP post SCI will be recruited and randomised to intervention and comparator groups. The primary outcomes are feasibility outcomes for progression to definitive trial which include recruitment and retention rates, adverse events and acceptability of the intervention. Secondary outcomes explore changes in NP intensity and interference as measured by the International Spinal Cord Injury Pain Basic Data Set 3.0 (ISCIPBDS) at baseline, post-intervention (week 13) and at 6-month follow-up. Conclusions There is a need to explore non-pharmacological management of NP after SCI. The findings of this feasibility trial will inform the development of a future multicentre, international RCT, Trial Registration NCT06463418, 08/07/2024, https://clinicaltrials.gov/study/NCT06463418.

Towards a comprehensive framework for risk assessment of organizational development project portfolios
Authors: Micán Camilo , Fernandes Gabriela , Araújo Madalena
Published: September 2024

The benefits of risk management in the context of project portfolios have been widely recognized in the literature. However, approaches that assess the risk of organizational development project portfolios from the perspective of how the portfolio delivers value to the parent organization remain largely unexplored. To address this gap, our research takes a constructivist approach and an organizational perspective on project portfolios. We conducted twenty-eight semi-structured interviews and used thematic analysis to identify and relate four themes of a comprehensive project portfolio risk assessment (PPRA) framework: "project portfolio as the organizational unit for PPRA"; "organizational capabilities as portfolio outcomes in which PPR can be assessed"; "project portfolio levels as sources of risk factors in PPRA"; and "balance between project portfolio attributes complexity". Within the framework of organizational development project portfolios, this study contributes to our understanding of PPRA by providing two propositions: (1) The capabilities to be generated by the project portfolio can be used as the portfolio primary results on which PPRA can assess the risk of the project portfolio, establishing the impact of PPR on the project portfolio value delivering to the parent organization, and (2) The risk factors that impact the project portfolio expected results can be represented into PPRA as ‘output-related’ risk factors and ‘outcome-related’ risk factors.
Less Artificial, More Intelligent: Understanding Affinity, Trustworthiness, and Preference for Digital Humans
Authors: Seymour Mike , Yuan Lingyao (Ivy) , Riemer Kai , Dennis Alan R.
Published: September 2024

Practice- and policy-oriented abstract:

Companies are increasingly deploying highly realistic digital human agents (DHAs) controlled by advanced AI for online customer service, tasks typically handled by chatbots. We conducted four experiments to assess users’ perceptions (trustworthiness, affinity, and willingness to work with) and behaviors while using DHAs, utilizing quantitative surveys, qualitative interviews, direct observations, and neurophysiological measurements. Our studies involved four DHAs, including two commercial products (found to be immature) and two future-focused ones (where participants believed the AI-controlled DHAs were human-controlled). In the first study, comparing perceptions of a DHA, chatbot, and human agent from descriptions revealed few differences between the DHA and chatbot. The second study, involving actual use of a commercial DHA, showed participants found it uncanny, robotic, or difficult to converse with. The third and fourth studies used a “Wizard of Oz” design, with participants believing a human-controlled DHA was AI-driven. Results showed a preference for human agents via video conferencing, but no significant differences between DHAs and human agents when visual fidelity was controlled. Current DHAs, despite communication issues, trigger more affinity than chatbots. When DHAs match human communication abilities, they are perceived similarly to human agents for simple tasks. This research also suggests DHAs may alleviate algorithm aversion.
The Minimax Property in Infinite Two-Person Win-Lose Games
Authors: Holzman Ron
Published: September 2024

We explore a version of the minimax theorem for two-person win-lose games with infinitely many pure strategies. In the countable case, we give a combinatorial condition on the game which implies the minimax property. In the general case, we prove that a game satisfies the minimax property along with all its subgames if and only if none of its subgames is isomorphic to the “larger number game.” This generalizes a recent theorem of Hanneke, Livni, and Moran. We also propose several applications of our results outside of game theory.

Desa Branta Pesisir, terletak di wilayah pesisir pantai selatan Kabupaten Pamekasan, Madura, Provinsi Jawa Timur, dikenal akan sumber daya lautnya yang melimpah, terutama dalam pemasaran ikan laut segar atau kering. Di antara kurang lebih 180 Usaha Kecil Menengah (UKM) di Branta Pesisir, UKM Dinny Home Industry adalah industri rumahan yang mengolah dan memasarkan makanan laut. Produk utama UKM Dinny adalah ikan krispi dan rambak kulit ikan, namun kemasannya generik, sehingga kurang dikenal dan tidak mencolok di pasar. Desain kemasan tidak mencerminkan kualitas, harga, dan karakter produk sebagai kuliner pesisir asal Madura dengan baik. Kemasan yang kurang persuasif juga menghambat penjualan dan kepercayaan diri pemilik untuk memamerkan produknya di festival atau event kuliner. Karena itu, Tim Pengabdi dan UKM Dinny sepakat bahwa permasalahan ini menjadi prioritas karena kemasan adalah bagian integral dari program pemasaran UKM, yang memengaruhi daya saing di pasar dan kelangsungan usaha. Dengan kegiatan abmas berbasis produk ini, tim pengabdi mengembangkan desain kemasan yang representatif dan media promosi untuk mengenalkan produk dan kemasan yang baru. Kegiatan ini mendukung pertumbuhan ekonomi berkelanjutan dan menciptakan pekerjaan yang layak (SDG 8), dan mendorong pola konsumsi dan produksi berkelanjutan (SDG 12), yang sangat penting terutama pasca pandemi Covid-19.

Objectives: to compare the color change and surface roughness of polyetheretherketones (PEEK) immersed in various beverages and mouthrinses for 7 days. Methods: the specimens were divided into 6 groups, 10 pieces per group, and each group was immersed in different solutions as followed: coffee, cola, red wine, distilled water, 0.5% povidone iodine, and 1% hydrogen peroxide. A color change (∆E*ab) was measured in each sample before and after 7 days of immersion in different solutions. At a significance level of 0.05, color change data were analyzed using one-way ANOVA and pairwise comparisons with the Games-Howell method, and surface roughness changes were analyzed using the Wilcoxon Sign-Rank test. Results: immersion of PEEK in 0.5% povidone iodine caused the most color change, followed by red wine when continuously immersed for 7 days. However, immersion in different types of solutions did not affect the surface roughness of PEEK. Conclusions: After 7 days of immersion, 0.5% povidone iodine and red wine caused color change in PEEK with no change in surface roughness

No abstract available. Article truncated after 150 words. A 79-year-old man presented to our institution for evaluation of intermittent fevers, profound nasal pain with congestion, cough, sore throat, voice changes, fatigue, generalized weakness, and loose stools which had been progressively affecting the patient for the last 6 months. The patient has a past medical history of ulcerative colitis, hypothyroidism, atrial fibrillation, and hypertension. Just preceding the onset of symptoms, the patient had gone on a month-long trip through Africa and Asia. His symptoms were presumed infectious in the outpatient setting and had responded somewhat to an extended course of ciprofloxacin and metronidazole. The patient had an outpatient head and neck CT that demonstrated significant mucosal thickening of the maxillary sinuses (Figure 3A). An outside hospital CT of the abdomen/pelvis was unremarkable aside from sigmoid diverticulosis. The patient’s significant nasal pain and congestion along with the fevers was suggestive of granulomatosis with polyangiitis (GPA). The differential also included hematologic …
