“It’s a matter of age”: Four dimensions of youths’ news consumption
Authors: Klopfenstein Frei Nadine , Wyss Valery , Gnach Aleksandra , Weber Wibke 
Published: September 2022

News media in Switzerland are confronted with the challenge of not reaching young people, as youth-specific news platforms and formats are not used by the target group. Our study aims to determine how and where young people can be reached with news. It uses a mixed methods approach to analyze the expectations of young people towards news content and formats and to determine their news consumption patterns. The results show that young people’s news consumption is characterized by four dimensions: 1. duration and times of consumption, 2. news consumption habits and behavior, 3. restrictions, 4. media literacy. The significance of these dimensions varies between three age groups determined through the study. The news consumption of the 12-to-14 year-olds is strongly restricted by parents and school. This group consumes news mainly through media available at home. In the group of 15- to-17 year-olds, parental influence and restrictions decrease, while peer influence increases. This age group spends a lot of time on social media platforms where young people stumble upon news rather accidentally. Between 18 and 20 years of age, news consumption stabilizes, and individual patterns emerge. This age group accesses news via selected apps and social media channels. Young people in Switzerland prefer visual formats like pictures, videos, and memes. When scrolling through social media platforms, they come across news content which arouses their interest in certain information and leads them to search for it on media websites. Swiss Youth wants to be informed about relevant news or topics that are “in vogue”.

ObjectivesMetabolic syndrome (MetS) and hepatitis C virus (HCV) are associated with a higher risk of impaired pulmonary function (iPF). This study aimed to investigate the relationships among MetS, iPF, and viral hepatitis.MethodsThis community-based study enrolled participants undergoing annual health check-ups in southern Taiwan between March and December 2019. We performed multivariable logistic regression analyses adjusted for demographics and characteristics to identify the factors associated with iPF.ResultsA total of 2337 participants completed examinations, of whom 928 (39.7%) had iPF. The participants with iPF were elderly (68.8  ±  12.8 years old) and predominately female (63%). MetS increased the risk of iPF (odds ratio (OR) 1.51, 95% confidence interval (CI) 1.27–1.81, p < 0.001). Beyond age (OR 1.03, 95% CI 1.02–1.04) and smoking (OR 1.309, 95% CI 1.004–1.705), female sex (OR 0.74, 95% CI 0.59–0.93) and high education level (OR 0.96, 95% CI 0.94–0.98, p < 0.001) protected against iPF. HCV was not significantly associated with iPF (OR 1.17, 95% CI 0.90–1.52, p  =  0.235) in multivariable analysis. MetS was associated with a higher risk of iPF in the non-HBV/HCV group (OR 1.86, 95% CI 1.54–2.26) and HBV alone group (OR 3.44, 95% CI 1.89–6.28), but not in the HCV alone group (OR 1.02, 95% CI 0.64–1.62).DiscussionMetS was an independent predictor of iPF, especially the restrictive type, and had different effects in the HBV/non-viral hepatitis and HCV groups. Female sex and education were inversely associated with iPF.

Published: September 2022

Background: Acute respiratory distress syndrome (ARDS) is a severe complication among patients with severe acute pancreatitis (SAP), which may be associated with increased mortality in hospitalized patients. Thus, an effective model to predict ARDS in patients with SAP is urgently required. Methods: We retrospectively analyzed the data from the patients with SAP who recruited in Xiangya Hospital between April 2017 and May 2021. Patients meeting the Berlin definition of ARDS were categorized into the ARDS group. Logistic regression models and a nomogram were utilized in the study. Descriptive statistics, logistic regression models, and a nomogram were used in the current study. Results: Comorbidity of ARDS occurred in 109 (46.58%) of 234 patients with SAP. The SAP patients with ARDS group had a higher 60-day mortality rate, an increased demand for invasive mechanical ventilation, and a longer intensive care unit (ICU) stay than those without ARDS ( p < .001 for all). Partial pressure of oxygen (PaO2): fraction of inspired oxygen (FiO2) < 200, platelets <125 × 109/L, lactate dehydrogenase >250 U/L, creatinine >111 mg/dL, and procalcitonin >0.5 ng/mL were independent risk variables for development of ARDS in SAP patients. The area under the curve for the model was 0.814, and the model fit was acceptable [ p = .355 (Hosmer–Lemeshow)]. Incorporating these 5 factors, a nomogram was established with sufficient discriminatory power (C-index 0.814). Calibration curve indicated the proper discrimination and good calibration in the predicting nomogram model. Conclusion: The prediction nomogram for ARDS in patients with SAP can be applied using clinical common variables after the diagnosis of SAP. Future studies would be warranted to verify the potential clinical benefits of this model.

Authors: Girma Andualem , Lamore Yonas 
Published: September 2022

Objective: Microorganisms are one of the main indoor air contaminants. In a hospital setting, a range of hospital-acquired infectious diseases are caused due to indoor air pollution. Studies conducted on hospital patients and healthcare workers revealed that indoor air pollution is causing more severe health problems than outdoor air pollution. Thus, this study aimed to determine the bacterial indoor air quality in Jimma University Specialized Hospital in southwest Ethiopia. Method: An institution-based cross-sectional study was conducted from late May to October 2020. Indoor air samples were collected through a passive method by exposing prepared sample plates for prescheduled exposure time, and bacterial species were identified using morphology and biochemical tests. Result: Based on the findings, neither of the wards showed a similar microbial concentration. Among the studied wards, the minimum and the maximum bacterial distribution ranged from 280 to 6369 cfu/m3, respectively. Staphylococcus aureus, coagulase-negative spp., Klebsiella spp., Escherichia coli, Bacillus spp., Proteus spp., and Streptococcus spp. were bacterial isolates. Statistically, the concentration of the bacteria in all the studied wards was tested significantly different ( p ⩽ 0.001). Conclusion: Among studied wards, the emergency outpatient ward showed a maximum bacterial concentration in contrast to the minor operating room. Based on the criteria of the World Health Organization on hospital-acquired infections, studied wards were highly contaminated.

Introduction: Stroke is the second-leading global cause of death next to ischemic heart disease. The burden of stroke mortality, morbidity, and disability is increasing across the world. In Ethiopia, evidence on the survival status of adult stroke patients is insufficient. The purpose of this study is to estimate in-hospital mortality and its predictors among adult stroke patients. Methods: Institution-based retrospective follow-up study was conducted on adult stroke patients who were admitted to Debre Markos Comprehensive Specialized Hospital from 1 November 2015 to 31 October 2020. Through simple random sampling, 382 patient charts were selected from 1125 stroke patients for 5 years follow-up period. Data were entered using EpiData™ version 4.1 and exported to Stata/SE™ version 14 for cleaning, coding, categorizing, and analysis. Predictor variables were selected using 95% confidence interval with a corresponding adjusted hazard ratio. Results: In this study, 219 (57.33%) males and the mean (standard deviation) age of 57.65 ± 14.3 years. The in-hospital mortality rate of stroke was 12.8%; the median (interquartile range) time to mortality and Glasgow Coma Scale were 7 (4–13) days and 14 (11–15), respectively. The incidence of in-hospital mortality was 29/1000, 11/1000, 8/1000, and 13.6/1000 person-days in the first, second, third, and end of follow-up weeks, respectively. Pneumonia (adjusted hazard ratio = 3.51 (95% confidence interval = 1.86, 6.61)), hemorrhagic stroke (adjusted hazard ratio = 2.03 (95% confidence interval = 1.03, 3.99)), moderate impairment Glasgow Coma Scale (9–12) (adjusted hazard ratio = 2.16 (95% confidence interval = 1.08, 4.29)), severe impairment Glasgow Coma Scale (3–8) (adjusted hazard ratio = 2.38 (95% confidence interval = 1.01, 5.67)), history of hypertension (adjusted hazard ratio = 2.01 (95% confidence interval = 1.08, 3.74)), and increased intracranial pressure (adjusted hazard ratio = 2.12 (95% confidence interval = 1.10, 4.07)) were statistically significant predictors for in-hospital mortality. Conclusion: In-hospital mortality of stroke was relatively high, and the median time to mortality was 8 days. Pneumonia, hemorrhagic stroke, Glasgow Coma Scale, history of hypertension, and increased intracranial pressure were identified predictors.

Published: September 2022

Background Osteoporotic vertebral compression fracture (OVCF) has become a health issue of worldwide concern. Percutaneous kyphoplasty (PKP) is one of the main surgical methods for OVCFs. This study aimed to evaluate and compare the clinical efficacy and safety of PKP with high- and low-viscosity bone cement for OVCFs. Methods Totally 62 patients with single-level OVCF were enrolled in this study from December 2018 to April 2021. Among them, 32 cases underwent PKP with high-viscosity bone cement, while 30 cases underwent PKP with low-viscosity bone cement. Visual analog scale (VAS) scores and Oswestry disability index (ODI) scores were used in the pre- and post-operative period to assess patients’ rehabilitation. Compression rates of anterior vertebra height (AVH) and posterior vertebra height (PVH) were analyzed to evaluate the restoration of vertebra height. Leakage rates and locations were recorded to show clinical safety. Results VAS and ODI scores both significantly improved in 2 groups at 1 day, 1 month, and 3 months after surgery. Compression rates of AVH and PVH at 1 day and 3 months after PKP were lower than those before surgery. However, there was no significant difference in VAS scores, ODI scores, and compression rates between both groups. However, PKP with high-viscosity bone cement achieved a lower bone cement leakage rate significantly, which showed the safety of high-viscosity bone cement in PKP. Conclusions PKP with high- and low-viscosity bone cement both improved the recovery of patients and restored vertebra heights. Notably, PKP with high-viscosity bone cement can achieve favorable clinical outcomes as well as lower bone cement leakage rate.

Published: September 2022

Introduction The optimal surgical treatment for Vancouver B2 and B3 fractures has not been determined, and bone defects and delays in fracture healing significantly affect treatment outcomes. Some authors have argued that when a serious bone defect is present, the use of cortical strut allografts for the treatment of type B2 and B3 periprosthetic femoral fractures (PFFs) after hip joint replacement may be beneficial. This study aimed to determine the usefulness of cortical strut allografts based on mid-to long-term clinical radiologic results after surgical treatment of Vancouver B-type PFFs. Methods We retrospectively reviewed the outcomes of 48 patients with postoperative PFFs. The mean duration of follow-up was 6.7 years. The 22 patients were treated with cortical strut allograft. Each case was characterized and described in detail, including the length of allograft and the union period, and possible correlations between allograft length and strut-to-host bone union were analyzed. Clinical evaluations included Parker mobility and Harris hip scores. At the final follow-up, we assessed the radiological results using the Beals and Tower’s criteria, stem subsidence, and fracture union time. Results All 48 fractures united at an average of 21.5 weeks, and strut-to-host bone union was typically observed within 32 months. No positive correlation was identified between the allograft length and incorporation period. There was one deep infection and four cases of dislocation, but there was no fracture or malunion of the cortical strut allografts. No evidence of femoral loosening was observed in any of the patients. Conclusion Cortical strut allografts used to treat type B PFFs showed high rates of bone union and survival. In mid-to long-term follow-up, the cortical strut allograft length did not affect to incorporation time. The author concluded that cortical strut allografts are useful treatment for PFFs regardless subtype classification of the Vancouver type B.

Study Design A modified Delphi study. Objective To assess current practice patterns in the management of cervical spinal cord injury (SCI) and develop a simplified, practical classification system which offers ease of use in the acute setting, incorporates modern diagnostic tools and provides utility in determining treatment strategies for cervical SCI. Methods A three-phase modified Delphi procedure was performed between April 2020 and December 2021. During the first phase, members of the AOSpine SCI Knowledge forum proposed variables of importance for classifying and treating cervical SCI. The second phase involved an international survey of spine surgeons gauging practices surrounding the role and timing of surgery for cervical SCI and opinions regarding factors which most influence these practices. For the third phase, information obtained from phases 1 and 2 were used to draft a new classification system. Results 396 surgeons responded to the survey. Neurological status, spinal stability and cord compression were the most important variables influencing decisions surrounding the role and timing of surgery. The majority (>50%) of respondents preferred to perform surgery within 24 hours post-SCI in clinical scenarios in which there was instability, severe cord compression or severe neurology. Situations in which <50% of respondents were inclined to operate early included: SCI with mild neurological impairments, with cord compression but without instability (with or without medical comorbidities), and SCI without cord compression or instability. Conclusions Spinal stability, cord compression and neurological status are the most important variables influencing surgeons’ practices surrounding the surgical management of cervical SCI. Based on these results, a simplified classification system for acute cervical SCI has been proposed.

Published: September 2022

Background: Ice hockey referees and linesmen are at risk for musculoskeletal injuries because of the lack of protective equipment and contact with players, sticks, pucks, the ice surface and boards. Purpose: To quantify and analyze injuries reported by officials of the International Ice Hockey Federation (IIHF). Study Design: Descriptive epidemiology study. Methods: A 61-question survey tool was designed by an interdisciplinary team to evaluate musculoskeletal injuries experienced by ice hockey officials. This survey was administered to 600 active IIHF referees and linesmen. Only completed survey responses were included in the statistical analysis. Continuous variables were analyzed using unpaired t-tests, while categorical data were assessed utilizing chi-square tests. Results: Of the 600 surveys administered, 264 surveys were completed by officials from 45 countries (44% response rate). Of the respondents, 72% were male, and 28% were female, with a mean age of 31.1 ± 5.8 years. Officiating experience averaged 11.4 ± 6.0 years (6.3 ± 4.5 years with the IIHF). A total of 295 injuries were reported by 55% of the officials. Injuries occurred more frequently during games compared with training, and officials who worked year-round had more total injuries than those who took time off ( P = .03). The most common injuries involved the wrist and hand (n = 64 [22%]), head and face (n = 58 [20%]), and the knee (n = 47 [16%]). Wrist and hand trauma included 23 fractures. Knee and shoulder injuries were most likely to require surgery compared with other body areas ( P < .001); 30 officials underwent surgery because of an acute knee injury (10%). Injury prevention activities were effective at reducing injuries ( P = .04). Conclusion: Most ice hockey officials experienced musculoskeletal injuries during their career. The risk of trauma to the wrist and hand can possibly be reduced via equipment modifications including protective gloves. A greater emphasis should be placed on injury prevention programs and time away from officiating competitions.

Published: September 2022

Introduction The COVID 19 pandemic increased the need for rapid and accurate diagnostic testing for COVID. When testing became available, a systems response was needed to efficiently accommodate the high-volume flow of patients who needed testing. Self-scheduling of COVID testing was developed to help patients safely and efficiently schedule their COVID testing online or with a mobile app. Methods We captured the counts of COVID test appointments, time patients spent in scheduling COVID test appointments, appointment lead times, and no-shows for COVID test appointments. For 17 months of self-scheduling, we retrospectively compared self-scheduling with the concurrent staff scheduling of COVID tests. Results From November 2020 through March 2022 there were 619 104 scheduled appointments for COVID testing with 22% (136 252) being self-scheduled. For asymptomatic self-scheduled COVID tests, accounting for 10.3% (63 605/619 104) of total COVID tests scheduled, median time to self-schedule was 3.1 min, interquartile range (IQR) [2.4,4.7]. For symptomatic self-schedulers accounting for 11.7% (72 647/619 104) of total COVID tests scheduled, the median time to self-triage and self-schedule was 5.8 min, IQR[4.3,8.9]. Self-scheduled COVID appointments increased to 44% (42 387/97 086) of the total COVID appointments during the peak month of January 2022. Median appointment lead time for symptomatic self-scheduled COVID test appointments was 6.6 h compared to 2.9 h ( P < .0001) for symptomatic staff scheduled appointments. However, adjusting for the 24% (32 194/135 252) that self-scheduled during hours when testing was unavailable, the median appointment lead time for symptomatic self-scheduled patients dropped to 3.6 h. No-shows were 2.5% for self-scheduled appointments compared to 3.0% no-shows that were staff scheduled (odds ratio 0.83, P < .0001). Conclusion COVID testing was self-scheduled for a large percent of scheduled COVID tests, taking patients only a few minutes to complete. Self-scheduling use increased over time, associated with a decreasing use of staff scheduled appointments and lower no-shows.

AbstractWodegongjieite occurs in the Cr-11 chromitite orebody of the Luobusa ophiolite in the Kangjinla district, Tibet, China. It is found in two inclusions in corundum: (1) as a partial overgrowth (holotype) up to 1.5 μm thick around a spheroid 20 μm across of wenjiite (Ti10(Si,P,□)7), kangjinlaite (Ti11(Si,P)10), zhiqinite (TiSi2) and badengzhuite (TiP), and (2) as pools up to 0.25 μm wide filling interstices between wenjiite, jingsuiite (TiB2), osbornite–khamrabaevite (Ti[N,C]) and corundum. Energy dispersive analyses gave Al2O334.09, SiO249.11, K2O 2.56, CaO 11.71, SrO 2.53, total 100.0 wt.%, corresponding to K0.58Sr0.26Ca2.25Al7.20Si8.80O31.20, ideally KCa3(Al7Si9)O32, for Si + Al = 16 cations.Single-crystal studies were carried out with three-dimensional electron diffraction providing data for anab initiostructure solution in the hexagonal space groupP6/mcc(#192) witha= 10.2(2) Å,c= 14.9(3) Å,V= 1340(50) Å3andZ= 2. Density (calc.) = 2.694 g⋅cm–3. The refinement, which assumes complete Si–Al disorder, gives averageT1–O andT2–O bond lengths both as 1.65 Å. It was not practical to use unconstrained refinement for the occupancies of the large cation sites 6fand 2a. Theab initiomodel shows clearly that the two cation sites have different sizes and coordination. Consequently, we imposed the condition (1) that all the K occupies the 2asite as the average K–O bond length of 3.07 Å is close to the average K–O bond lengths reported in kokchetavite and (2) that all the Ca occupies the 6fsite as the average Ca–O bond length of 2.60 Å (2.36 Å and 2.84 Å for Ca–O1 and Ca–O3, respectively) is reasonable for Ca–O. Assuming that all K and all Ca are located at the 2asite and 6fsite, respectively, Sr occupancies of these sites could be refined. Thermal parameters are positive and in a reasonable range. The structure is a sheet silicate isostructural with the K-feldspar polymorph kokchetavite, with two crystallographically distinct sites for K, but not with the topologically identical anorthite polymorph dmisteinbergite (CaAl2Si2O8) with only a single site for Ca. Substitution of K by Ca at the 6fsite is associated with marked rotation of the Si,Al tetrahedra and a collapse of the structure to accommodate the smaller Ca ion.The spheroid of intermetallic phases is believed to have formed from the interaction of mantle-derived CH4+ H2fluids with basaltic magmas at depths of ~30–100 km, resulting in precipitation of corundum that entrapped intermetallic melts. Associated immiscible silicate melt of granodioritic composition crystallised metastably to wodegongjieite instead of a mixture of anorthite and K-feldspar.
