Nasal steroid use and osteitis development in chronic rhinosinusitis with nasal polyps
Authors: Şimşek Sadullah , İşlek Akif 
Published: October 2022

Abstract
Objectives
Osteitis and tissue remodeling are inflammatory processes associated with the severity of chronic rhinosinusitis with nasal polyps (CRSwNP). Nasal steroids are the mainly recommended therapeutics in the treatment of the disease, and besides their beneficial effects, they may worsen osteitis via osteopenia. This study aimed to search for the coalescence of osteitis in CRSwNP and nasal steroid use (NSU).

Methods
A cross-sectional study was designed. Patients who underwent paranasal sinus computed tomography (PNSCT) imaging were queried, and the sino‐nasal outcome test-22 (SNOT-22) was completed. Regular NSU was defined as a continued treatment for 2 months in the last 6 months. The cumulative period of NSU during the last 6 months was determined and classified as no use or, for 1 to 3 months, or more than 3 months. Lund-MacKay scores (LMS) and Global Osteitis Scores (GOS) were calculated for 10 sinuses via PNSCT.

Results
Sixty-two patients were included in the study. The mean GOS score was 5.7 ± 1.7 points higher in patients with regular NSU (p = 0.002, 95% CI: 9.2–2.2, t-test). LMS and SNOT-22 scores also were significantly higher for patients with regular NSU (p = 0.036 and < 0.001 consecutively). The mean GOS score showed a significant increase according to the cumulative period of NSU (p < 0.001, one-way ANOVA test). Similarly, LMS and SNOT-22 scores were also significantly associated with the duration of total NSU. GOS score showed a significant positive high correlation with LMS and SNOT-22 scores (p < 0.001, r = 0.608 and r = 0.753 consecutively).

Conclusions
This association found between the severity of GOS and NSU is probably due to the severity of the disease. However, it may question the value of the NSU effect in the development of osteitis. The presence of NSU should be investigated in future histopathological studies.

Authors: Mazlan Rafidah , Raman Kausallya , Abdullah Asma 
Published: October 2022

AbstractBackgroundUniversal newborn hearing screening (UNHS) has been widely adopted worldwide as a standard of care because it enables the detection of congenital hearing loss early in life. Therefore, the concepts of regular measurement of performance using pre-determined quality measures are recommended for continuous improvement of the program. This study aimed to evaluate and update the performance of a UNHS program by measuring the recommended quality measures between 2010 and 2019. A retrospective study analyzing data of 50569 babies screened between January 2010 and December 2019 was performed. The pre-determined quality measures of coverage rate, initial referral rate, return to follow-up rate, diagnosis rate, and age at diagnosis were measured.ResultsThe average coverage rate was 95.5%, with all years achieving the recommended benchmark of ≥ 95% except 2014 (91.8%) and 2019 (89.5%). Generally, the initial referral rate (10%) exceeded the benchmark of ≤ 4%. The program only managed to reach the benchmark for initial referral rate in 2013, 2014, and 2015. Both quality indicators for return to follow-up and diagnosis rates also did not meet the ≥ 95% and ≥ 90% standards, respectively. The return to follow-up ranged from 62 to 72.7%, while the average diagnosis rate was 73.4% (60–100%). One hundred thirty-seven infants were diagnosed with hearing loss at a median age of 3.8 months (± 0.4 months), resulting in a prevalence of 0.27%.ConclusionThe findings demonstrated an excellent coverage rate but unsatisfactory performance for other quality indicators. Hence, the current program needs to be revisited to remain relevant and effective.

Published: October 2022

Abstract
Background
Acute invasive fungal rhinosinusitis (AIFRS) is a rare aggressive life-threatening infection that affects immunocompromised individuals. Recently, an increase in the incidence of this infection has been reported in patients who have SARS-CoV-2 infection or recently recovered. This study was to assess the outcome and define risk factors that might affect the outcome in SARS-CoV-2-related AIFRS. A prospective observational study included 54 patients diagnosed with SARS-CoV-2-related AIFRS. Controlling the predisposing factors, systemic antifungal, and early surgical debridement was performed. The mortality rate was calculated. Age, sex, underlying risk factors, the extent of the disease, debridement technique, and other biochemical variables were evaluated regarding their impact on survival. Patients were followed up for 3 months.

Results
Fifty-four patients with a mean age of 48.1 years. Diabetes mellitus was the most common comorbidity affecting 52 patients (96.3%). Intracranial and intraorbital extension had a predictive value for mortality (P value 0.050 and 0.049 respectively). However, only intracranial extension was the independent predictor of mortality. Biochemical variables were higher than the normal range, but only serum ferritin level above 165 ng/ml was an independent predictor of mortality in patients with AIFR. The mortality rate was 38.9%.

Conclusion
The extent of the disease has a major impact on survival, so early diagnosis of AIFRS within patients infected with SARS-CoV-2 or recently recovered is essential to reduce mortality.
Deep-learning missing well-log prediction via long short-term memory network with attention-period mechanism

Published: October 2022

Underground reservoir information can be obtained through well-log interpretation. However, some logs might be missing due to various reasons, such as instrument failure. A deep-learning-based method that combines a convolutional layer and a long short-term memory (LSTM) layer is proposed to estimate the missing logs without the expensive relogging. The convolutional layer is used to extract the depth-series features initially, which are then input into the LSTM layer. To improve the feature memory and extraction capabilities of the LSTM layer, we construct two LSTM-based components: the first component uses an attention mechanism to optimize the LSTM units by adaptively adjusting network weights, and the second component uses a period-skip mechanism, which enhances the sensitivity of aperiodic changes in the depth series by learning the information of the shallow sequence. In addition, we add an autoregressive component to enhance the linear feature extraction capability while learning the nonlinear relationship between different logs. A total of 13 wells from two different regions are used for experiments, including 11 training and two test wells. We use one well to calculate the uncertainties of four time-series networks, i.e., our proposed network and three benchmark models (recurrent neural network, gated recurrent unit, and LSTM), to demonstrate the stability and robustness of the proposed method. Furthermore, we evaluate the performance of our proposed method in several crossover experiments, e.g., different logging intervals, depths, and input logs. Compared to a state-of-the-art deep learning method and a classic LSTM network, the proposed network has higher reliability, which is reflected in the feature extraction of depth series with a larger span. The experimental results demonstrate that our proposed network can accurately generate sonic and other unknown logs.
Low-frequency ambient ocean-bottom node surface-wave seismology: A Gulf of Mexico case history
Authors: Girard Aaron J. , Shragge Jeffrey , Olofsson Bjorn 
Published: October 2022

Long-time marine seismic recordings are becoming more common with the increased use of ocean-bottom nodes (OBNs), which can measure ambient seismic energy at frequencies lower than the typical minimum values in active-source compressed air-gun surveys. Interferometric processing on long-time ambient multicomponent data allows for the extraction of low-frequency (sub-2.0 Hz) responses in virtual source gathers (VSGs). Using 40 days of continuous OBN recordings acquired on a large dense array during a field experiment in the Gulf of Mexico, we find that sub-2.0 Hz surface-wave energy in the computed VSGs is strongly coherent and exhibits an identifiable spatially varying character. In particular, after rotating the data components from a Cartesian geographic into a polar wave-vector reference frame, we find that radial VSGs (i.e., oriented along the vector connecting the virtual source and receiver) clearly indicate that surface-wave propagation is influenced by salt bodies as identified in a colocated active-source survey situated at a minimum of 0.7 km depth below the seafloor, an observation consistent with calculated 0.25–0.50 Hz surface-wave sensitivity kernels. This suggests that low-frequency ambient OBN surface-wave seismology could be important for estimating the long-wavelength elastic material properties (particularly S-wave velocity) and identifying the lateral boundaries of salt bodies without any prior knowledge of subsurface geology.

Tropical sprue (TS) is a post-infective disease of the small bowel characterized by a malabsorption syndrome affecting tropics inhabitants and visitors. Diagnosis of TS remain challenging since it can be confused with common diarrheal diseases, especially in non-endemic areas. We report a Tunisian case of latent TS. A 58-year-old male with a history of chronic watery diarrhea, was admitted to the intensive care unit for confusion which was related to severe metabolic acidosis. Despite the neurological improvement after hydro-electrolytic resuscitation and acid-base disorders correction, the patient continued to have three to five loose stools daily. A nutritional assessment showed a malabsorption syndrome: iron, Vitamin B12 and folate deficiencies; normochromic normocytic anemia and hypoalbuminemia. Gastrointestinal endoscopy showed duodenal villous atrophy and biopsy confirmed subtotal villous atrophy with increased intraepithelial lymphocytosis and a thickened hyalonalized sub-epithelial basal lamina. Celiac disease was evoked, however the patient did not improve on a gluten-free diet and the celiac serology was negative. On re-interviewing, we discovered that the patient had spent two months in India three years prior. Given the travel history, clinico-biological and histological data TS was highly considered and a good response to a five-month antibiotic course combined to nutritional supplementation supported this diagnosis. Clinico-biological, endoscopic and histological findings were overlapping between TS and other malabsorption diseases, explaining diagnosis difficulties. TS should be systematically discussed in tropics visitors presenting with chronic diarrhea. Improvement after micronutrient and vitamin deficiencies replacement combined to a prolonged antibiotic course supports the diagnosis of TS.

Background: The measures taken to contain the COVID-19 pandemic, led to significant changes in university education, resulting in the new normal standard of virtual teaching in many undergraduate medical schools worldwide. Therefore, the aim of this paper was to determine the factors related to academic satisfaction with virtual teaching in medical students during the COVID-19 pandemic. Methods: A cross-sectional-analytical study was conducted on medical students at a private university in Peru, through self-reported questionnaires divided into sociodemographic data and variables of interest that could influence academic satisfaction during the pandemic. To evaluate possible factors related to academic satisfaction, stepwise regression models were performed for both sexes. Results: In total, data from 310 medical students, 117 males and 193 females, were analyzed. Academic satisfaction reached a score of 11.2 ± 2.9, which was similar in both sexes. The best regression model for males (AIC: 544.32; RMSE: 2.42; R2: 0.30) showed that adaptation to university life (favorable change) and depression (unfavorable change) explained 30% of changes in students' academic satisfaction. While in females (AIC: 907.59; RMSE: 2.49; R 2: 0.22) the model integrated favorable factors such as adjustment to college life and anxiety; while depression and poor sleep quality were unfavorable factors. Conclusion: Factors that contributed to academic satisfaction in medical students were determined in this study, which differed by gender. Thus, it is important to take into account the particularities of male and female medical students in order to improve their academic satisfaction during their university careers.
Transplantation in the opinion of operating nurses
Authors: Majchrowicz Bożena 
Published: October 2022

Transplant surgery has become the standard method of treating many diseases that were fatal until recently. Doubts in this matter, regardless of the effectiveness of this method of saving human life, still exist in the public opinion. There are still stereotypes that inhibit the development of transplantology as a field of science.
The aim of the research was to present the opinions of the surveyed operating nurses on transplantation
Material and methods: The research was conducted on social networks in a group associating operating nurses in January and February 2021. 193 medical nurse nurses participated in them. The research method was a diagnostic survey and the tool was the original questionnaire. During the statistical analysis, the Chi2 test as well as the Kendall Tau-b and Kendall Tau-c correlations were used to check the significance of the relationship between the variables built on the qualitative scales.
Results and conclusions: 95.1% of the surveyed nurses considered transplantation saving lives. 49.5% of the respondents believe that the best way to regulate the procurement of organs for transplantation is consent given in life. An equally large group of respondents, 34.0%, say that it is enough not to object while living. The respondents support the transplant procedure due to their high awareness in this regard. They know that transplant operations save people's lives and are safe for living donors.
Product Market Competition and Corporate Relocations: Evidence from the Supply Chain
Authors: Chen Chen , Dasgupta Sudipto , Huynh Thanh D. , Xia Ying 
Published: October 2022

We show that intensified competition changes the location of business activity and, in turn, affects supply chain relationships. Using establishment-level data, we find that, when upstream product markets become more competitive, suppliers are more likely to relocate their establishments closer to customers. Following the supplier’s relocation, its sales to the customer increase, its relationship with the customer is less likely to be terminated, and its innovation is more aligned with the customer’s innovation. The relocated supplier also experiences more analyst following and institutional ownership that are in common with the customer and is more likely to issue equity than debt. However, the improved relationship, by causing the supplier to engage more in innovation dedicated to the customer, adversely affects creative innovation, which is known to drive growth.

Scoring a Touchdown with Variable Pricing: Evidence from a Quasi-Experiment in the NFL Ticket Markets
Authors: Arslan Hayri A. , Tereyağoğlu Necati , Yılmaz Övünç 
Published: October 2022

Although variable pricing enables sports teams to respond to changing demand across games, reports point to somewhat limited implementation. In this paper, we study the implications of a switch to variable pricing on the primary and resale ticket markets using quasi-experimental data from the National Football League. Applying a difference-in-differences technique with propensity score weighting, we first show that the adoption of variable pricing increases primary market ticket sales by 1.59% per game. We then explore the mechanism behind this positive impact. We find that lower prices for the less attractive games are well received by customers, and customers do not have an unfavorable response to higher prices for the more attractive games. Our analysis of the customers’ activities in the resale market shows that the minimum resale market prices increase for the more attractive games following the switch to variable pricing. This analysis provides evidence for the increase in the option value created by the resale market and explains the positive response to higher prices for the more attractive games. Finally, we investigate when variable pricing is likely to be the most effective. We find that variable pricing has greater success in team hometowns with lower income levels and higher income diversity, and creating more game tiers in variable pricing leads to higher sales.This paper was accepted by Gabriel Weintraub, revenue management and market analytics.Supplemental Material: The data files and online appendix are available at https://doi.org/10.1287/mnsc.2022.4588 .
Follow the Crowd with Uncertain Service Capacity
Authors: Yang Liu , Shang Weixin , Liu Liming 
Published: October 2022

Problem definition: Customer joining behavior is of major concern for service systems where the service capacity is uncertain. Academic/practical relevance: It remains unclear whether customer inference of uncertain service capacity can lead to follow the crowd (FTC) behavior. Management can release capacity information, but how it affects system performance needs to be understood. Methodology: We use a single-server queue to analyze the joining behavior of customers who infer the actual service capacity based on the queue length upon arrival. We also characterize the impact of capacity information disclosure both analytically and numerically. Results: We find that when other customers’ tendency to join the service increases, a tagged customer can make more accurate inferences of service capacity based on queue length. This inference effect arises together with the congestion effect and can lead to FTC when it outweighs the latter. When multiple equilibria exist, we characterize the conditions under which the inference effect is significant at the aggregate customer level so that the joining equilibrium with a larger joining threshold is Pareto-optimal. Managerial implications: Management needs to be careful in setting the information disclosure policy, as the key problem parameters may affect its impact on system throughput and social welfare in opposite directions.

Authors: Saleh Dedawan S. , Ahmad Saddon T. , Kareem Sarmad R. 
Published: October 2022

In this study, the activity concentration of 40K and its’ concentrations in 24 different types of fruits were determined using high purity germanium (HPGe) and sodium iodide scintillation (NaI) detectors. The results of the two measurements are consistent. The Maximum and minimum activities of 40K in dry samples were 750.61 ± 11.88 and 15.64 ± 0.86 Bq kg−1 in apricot and olive, respectively, while in fresh samples they were 152.27 ± 2.12 and 1.99 ± 0.11 Bq kg−1 in dates and olive, respectively. The highest and lowest potassium contents were 489.81 and 6.42 mg/100gm in fresh dates and olives, respectively. Drupe and Tropical fruits, as a fruit family, typically had the highest level of 40K activity and potassium concentration, whereas pome fruits showed the lowest levels. Many of these commonly consumed fresh fruits with rich potassium and water contents are lowering hypertension and improving the hydration status (HS) in people's nutrition. The rate of potassium-40 and total potassium concentration intake for a single unit or portion of the fruits was calculated.
Using discussion forums to support continuing education of workplace learning supervisors: enabling a community of practice
Authors: Clarke Deb 
Published: October 2022

Workplace learning (WPL) supervisors play a significant and fundamental role in enhancing university students’ experiences during their placements. Supervision is a multi-faceted and complex interpersonal and professional activity, which requires continued education to ensure contemporary knowledge, practice and capacity. Increasingly universities are viewing the offering of continued education for industry supervisors as an aspect of their mandate. This research reports on the design, facilitation and evaluation of an online learning module, supported by an asynchronous discussion forum aimed at building capacity of WPL supervisors, and developing cross-disciplinary WPL relationships.
Using a mixed method approach, data were gathered using crude statistical measures including frequency counts of discussion postings, layered with thematic analysis of supervisors’ postings to weekly learning activity stimuli. The results of the research illustrate the powerful opportunities for continued education offered by participation in a purposely designed and supported discussion forum. Participants felt empowered, supported by their online colleagues and enlightened by their enhanced awareness of others’ practices and perspectives. Participants’ capacity to further disseminate their embellished understandings of WPL supervision bought to the fore the far-reaching possibilities of discussion forum use in building professional communities of practice and professional capacity.
