Abstract
Background
Providing a stable osteosynthesis in fragility fractures of the pelvis can be challenging. Cement augmentation increases screw fixation in osteoporotic bone. Generating interfragmentary compression by using a lag screw also improves the stability. However, it is not known if interfragmentary compression can be achieved in osteoporotic sacral bone by cement augmentation of lag screws.
The purpose of this study was to compare cement-augmented sacroiliac screw osteosynthesis using partially versus fully threaded screws in osteoporotic hemipelvises concerning compression of fracture gap and pull-out force.

Methods
Nine fresh-frozen human cadaveric pelvises with osteoporosis were used. In all specimens, one side was treated with an augmented fully threaded screw (group A), and the other side with an augmented partially threaded screw (group B) after generating a vertical osteotomy on both sides of each sacrum. Afterwards, first a compression test with fracture gap measurement after tightening of the screws was performed, followed by an axial pull-out test measuring the maximum pull-out force of the screws.

Results
The fracture gap was significantly wider in group A (mean: 1.90 mm; SD: 1.64) than in group B (mean: 0.91 mm; SD: 1.03; p = 0.028).
Pull-out force was higher in group A (mean: 1696 N; SD: 1452) than in group B (mean: 1616 N; SD: 824), but this difference was not statistically significant (p = 0.767).

Conclusions
Cement augmentation of partially threaded screws in sacroiliac screw fixation allows narrowing of the fracture gap even in osteoporotic bone, while resistance against pull-out force is not significantly lower in partially threaded screws compared to fully threaded screws.

Published: December 2021

Abstract
Objective
This study was aimed to evaluate the effect of preoperative composite inflammatory index on adhesional perinephric fat (APF), providing a help for preoperative risk assessment of laparoscopic partial nephrectomy (LPN) in patients with renal cell carcinoma.

Materials and methods
A retrospective study was conducted on 231 patients with renal cell carcinoma, who underwent laparoscopic partial nephrectomy. They were divided into two groups according to whether there was APF during operation. Relevant clinical data, laboratory parameters and imaging examination were obtained before operation to calculate the composite inflammatory index and MAP score. The composite inflammatory index was divided into high value group and low value group by ROC curve method. The related predictive factors of APF were analyzed by logistic regression method.

Results
The APF was found in 105 patients (45.5%). In multivariate analysis, systemic immune inflammation index (SII) (high/low), MAP score, tumor size and perirenal fat thickness were independent predictors of APF. The operation time of patients with APF was longer, and the difference of blood loss was not statistically significant.

Conclusion
SII is an independent predictor of APF before laparoscopic partial nephrectomy.

Authors: Balay-odao Ejercito Mangawa , Alquwez Nahed , Al Thobaity Abdulellah , Al Otaibi Khalaf , Alsakran Yousef Ali Abdulrahman , Cruz Jonas Preposi 
Published: December 2021

Abstract
Background
Every person has a persona (or mask) which is the façade that every person shows to the world. Thus, males use façade to reveal or conceal their true feelings and emotions. Also, the male uses mental health façade to protect themselves from prejudice and judgment. Thus, the study aimed to explore the experiences of male Saudi nursing students of mental health.

Method
Husserl’s descriptive phenomenology was used as a guiding lens to explore. Eleven participants were involved in the study by using the referral sampling technique. An unstructured interview was performed to gather information from the participants. The seven steps of the descriptive Colaizzi process were followed to investigate and examine the obtained data. The credibility, dependability, confirmability, transferability, and reflexivity criteria were observed to ensure the rigor of the study.

Results
The findings have two major themes. The first theme is the unadulterated smile that describes optimism in the family and mutual guarantee. The second theme is the orchestrated smile, which describes avoiding diverting burdens, social responsibility, protection of self, and reputation.

Conclusions
The findings document that the mental health façade of male Saudi nursing students is associated with the expectation of family optimism, mutual guarantee, the expectation of society, and self-protection.

AbstractRed pepper is enriched in antioxidant components, such as carotenoids, phenolic compounds, and vitamins. In this study, we investigated the natural variability in the content of carotenoids and phenolic acids in 11 red pepper cultivars grown in two locations in South Korea during 2016, 2017, and 2018. Seven carotenoids and six phenolic acids, including soluble and insoluble forms, were detected in the red fruit pericarps. The major carotenoids were β-carotene (40%) and capsanthin (20%). The content of insoluble phenolic acids was higher than that of soluble phenolic acids because of the large amount of insoluble p-coumaric acid. The statistical analysis of combined data showed significant differences among varieties, locations, and years for most of the measured components. The results from variance component analysis indicated that the effects of location, year and the interaction of location and year mainly accounted for the variation in carotenoids, whereas variations in phenolic acid content were attributed to year and variety. In addition, the results of principal component analysis and orthogonal partial least-squares discriminant showed that carotenoids were well discriminated by location and year, whereas phenolic acids were distinctively separated only by year. The data from this study could explain the natural variation in the content of carotenoids and phenolic acids in red pepper fruits by genotype and environment.
Ancient basketry on the inside: X-ray computed microtomography for the non-destructive assessment of small archaeological monocotyledonous fragments: examples from Southeast Europe
Authors: Andonova Mila 
Published: December 2021

Abstract
This study proposes non-destructive assessment instrumentation, the X-ray MicroCT scanning, to evaluate archaeological basketry remains prior to any destructive analysis. Three case studies are originating from two archaeological sites in Southeast Europe, with three different stages of preservation (poor, sufficient and very good). In addition, there are two preservation modes—charring and desiccation—along with two conservation situations: treated and untreated with conservation agent fragments. The three different scenarios were chosen to explore the potential range of X-ray MicroCT scanning technology when applied to monocotyledonous small-sized archaeological remains. It was proved that this non-invasive X-ray method is particularly suitable for the often-disadvantaged ancient basketry remains.

Published: December 2021

AbstractThe surfaces of the Martian moons, Phobos and Deimos may offer a stable environment for long-term operation of platforms. We present a broad assessment of potential scientific investigations, as well as strategic and operational opportunities offered by long-term operation of an instrumented lander. Studies using observations of Mars’ moons, and the detailed new findings expected from the JAXA Martian Moons eXploration (MMX) mission, International Mars Sample Return (MSR) Campaign and other upcoming Mars missions, provide a driver for feasibility and trade studies for follow-on missions that would build on the knowledge gain from those missions. We discuss the scientific questions and operational objectives that may be pertinent for landed platforms on the martian moons, including (1) monitoring and scientific investigations of Mars’ surface and atmosphere, (2) scientific investigations of the martian moons, (3) monitoring and scientific investigations of the space environment, (4) data relay for Mars surface assets or interplanetary missions and 5) use in a Mars navigation/positioning system. We present results from visibility calculations performed using the SPICE observation geometry system for space science missions, and a Phobos shape model. We compute as a function of location on Phobos, visibility quantities that are most relevant to science and operational objectives. These include visibility from Phobos of the Sun, Earth, Mars surface and atmosphere, Deimos, and Jupiter. We also consider occultation events by the Mars atmosphere of Earth and Deimos that may provide opportunities for radio science. Calculations are performed for a study period spanning one Mars year in a hypothetical future operational scenario (1 Jan 2030–18 Nov 2031). We combine visibility metrics to identify locations on Phobos most suitable for long-term operation of a platform. We find the Mars-facing side of Phobos, and limited areas on the leading and trailing sides, satisfy the most requirements defined for Mars and Phobos science, space environment monitoring, and data relay/navigation. We demonstrate that compliance with requirements related to visibility of Mars and its atmosphere are not mutually exclusive with those that are better satisfied on Phobos’ anti-Mars side, such as those aided by maximizing their cumulative view factor to the ecliptic plane (i.e. visibility to the Sun, Earth or outer solar system). Finally, our methodology allows to assess the extent to which combined visibility metrics can meet mission requirements. The process we describe can be used to support landing site identification and selection on planets, moons and small bodies.

The military as a neglected pathogen transmitter, from the nineteenth century to COVID-19: a systematic review
Authors: Chaufan Claudia , Dutescu Ilinca A. , Fekre Hanah , Marzabadi Saba , Noh K. J. 
Published: December 2021

Abstract
Background
The risk of outbreaks escalating into pandemics has soared with globalization. Therefore, understanding transmission mechanisms of infectious diseases has become critical to formulating global public health policy. This systematic review assessed evidence in the medical and public health literature for the military as a disease vector.

Methods
We searched 3 electronic databases without temporal restrictions. Two researchers independently extracted study data using a standardized form. Through team discussions, studies were grouped according to their type of transmission mechanism and direct quotes were extracted to generate themes and sub-themes. A content analysis was later performed and frequency distributions for each theme were generated.

Results
Of 6477 studies, 210 met our inclusion criteria and provided evidence, spanning over two centuries (1810–2020), for the military as a pathogen transmitter, within itself or between it and civilians. Biological mechanisms driving transmission included person-to-person transmission, contaminated food and water, vector-borne, and airborne routes. Contaminated food and/or water were the most common biological transmission route. Social mechanisms facilitating transmission included crowded living spaces, unhygienic conditions, strenuous working, training conditions, absent or inadequate vaccination programs, pressure from military leadership, poor compliance with public health advice, contractor mismanagement, high-risk behaviours, and occupation-specific freedom of movement. Living conditions were the most common social transmission mechanism, with young, low ranking military personnel repeatedly reported as the most affected group. Selected social mechanisms, such as employment-related freedom of movement, were unique to the military as a social institution. While few studies explicitly studied civilian populations, considerably more contained information that implied that civilians were likely impacted by outbreaks described in the military.

Conclusions
This study identified features of the military that pose a significant threat to global health, especially to civilian health in countries with substantial military presence or underdeveloped health systems. While biological transmission mechanisms are shared by other social groups, selected social transmission mechanisms are unique to the military. As an increasingly interconnected world faces the challenges of COVID-19 and future infectious diseases, the identified features of the military may exacerbate current and similar challenges and impair attempts to implement successful and equitable global public health policies.

Published: December 2021

Abstract

Context
Adrenal insufficiency (AI) is an uncommon, life-threatening disorder requiring lifelong treatment with steroid therapy and special attention to prevent adrenal crisis. Little is known about the prevalence of AI in Canada or healthcare utilization rates by these patients.

Objective
We aimed to assess the prevalence and healthcare burden of AI in Alberta, Canada.

Methods
This study used a population-based, retrospective administrative health data approach to identify patients with a diagnosis of AI over a 5-year period and evaluated emergency and outpatient healthcare utilization rates, steroid dispense records, and visit reasons.

Results
The period prevalence of AI was 839 per million adults. Patients made an average of 2.3 and 17.8 visits per year in the emergency department and outpatient settings, respectively. This was 3 to 4 times as frequent as the average Albertan, and only 5% were coded as visits for AI. The majority of patients were dispensed glucocorticoid medications only.

Conclusion
The prevalence of AI in Alberta is higher than published data in other locations. The frequency of visits suggests a significant healthcare burden and emphasizes the need for a strong understanding of this condition across all clinical settings. Our most concerning finding is that 94.3% of visits were not labeled with AI, even though many of the top presenting complaints were consistent with adrenal crisis. Several data limitations were discovered that suggest improvements in the standardization of data submission and coding can expand the yield of future studies using this method.
From Exile to “Retro-Utopia”
Authors: Popović Djordje 
Published: December 2021

Abstract
The act of writing ensures that exile is never permanent in the mind of the writer even if it is an abiding feature of his or her reality. Dubravka Ugrešić explores this paradox in much of her work, suggesting that migrant writers experience “double exile”—first on account of displacement and then because they are forced to reflect on the condition of being displaced, in effect, staging their alienation in the act of commenting on it. This dialectic of permanence and impermanence alone hints at a more developed relationship between home and exile than is usually allowed in the ontologically inflected interpretations of Ugrešić’s work. Instead of valorizing exile as a desirable, paradigmatically human condition, this article shows Ugrešić breaking with exilic literary and theoretical conventions by advancing the possibility of a return to what she calls “retro-utopia”—a place glimpsed in an unfulfilled past and a home to which a community based on shared positions, not identity, can return. The argument is based on an exegetical approach to an ur-document in transnational post-Yugoslav literature, Ugrešić’s 1997 novel The Museum of Unconditional Surrender, as well as on a key distinction in Edward Said’s secular criticism between filiative and affiliative social bonds.
Health professionals’ views of the first national GP payment scheme for structured type 2 diabetes care in Ireland: a qualitative study
Authors: McGrath Niamh , Riordan Fiona , Kearney Patricia M , O'Neill Kate , McHugh Sheena M 
Published: December 2021

Background: Payment schemes are widely used to improve chronic disease management in general practice. Although stakeholder views of such schemes could provide valuable learning regarding aspects that work and those which are more difficult to implement, there is a paucity of such data. We explored health professionals’ views of the implementation of the first national general practice payment scheme for type 2 diabetes (T2DM) care in Ireland, the ‘cycle of care’. Methods: Qualitative data were drawn from a multiple case study evaluating the implementation of a National Clinical Programme for Diabetes, collected from April 2016 to June 2017. Interview and focus group transcripts from participants involved in providing diabetes management in general practice and who referenced the cycle of care were eligible for inclusion in the current analysis. Data were analysed using reflective thematic analysis. Results: We analysed data from 28 participants comprising general practitioners (GPs) (n=8), practice nurses (n=9) and diabetes nurse specialists (DNS) (n=11). Participants perceived the cycle of care as “not adequate, but…a good start” to improve T2DM care in general practice in Ireland. Perceived benefits were greater financial viability for T2DM management in general practice, fostering a more proactive approach to T2DM care, delivery of T2DM care closer to patients’ homes, and increased use of other community diabetes services e.g., DNS and podiatry. Participants identified the limited resource for practice nurse time, inflexibility to provide care based on patient need and issues with data submission as drawbacks of the cycle of care. Conclusions: The cycle of care was viewed as a positive first step to increase and improve T2DM care delivered in general practice in Ireland. The implementation issues identified in this study should be considered in the design of future payment schemes targeting chronic disease management in general practice.
A systematic review of phage therapy applied to bone and joint infections: an analysis of success rates, treatment modalities and safety

Published: December 2021

Bone and joint infections are difficult to treat, and increasing antibiotic resistance has only made them more challenging. This has led to renewed interest in phage therapy (PT). The aim of this systematic review was to determine success rate, current treatment modalities and safety of PT in bone and joint infections.A systematic search of PubMed, EMBASE and Cochrane databases as well as the journalPHAGEfor literature published between January 2000 and April 2021 was conducted according to PRISMA guidelines to identify all human studies assessing bacteriophages as therapy for bone and joint infections. All study designs and patient populations were eligible. The review’s primary outcome was success rate.Twenty records describing a total of 51 patients and 52 treatment episodes were included. No randomized controlled studies were identified. The overall success rate was 71% (n= 37/52). Topical administration alone was the most frequent administration route (85%,n= 44/52). Antibiotics were administered concomitantly with PT in the majority of treatments (79%,n= 41/52), and surgery was performed for 87% (n= 45/52) of treatment episodes. Four minor adverse events related to PT were reported, representing 8% (n= 4/52) of treatment episodes.PT for bone and joint infections has not been evaluated in any randomized controlled clinical study, and current administration modalities are highly variable between case reports and case series. While publications included here show potential benefit and few adverse effects, clinical trials are warranted to assess the efficacy of PT for bone and joint infections and determine optimal treatment modalities.Cite this article:EFORT Open Rev2021;6:1148-1156.

Tunable dual-channel slow light in a graphene grating plasmonic waveguide
Authors: Zhang Yingqiu , Wu Qiaohua , Cui Jingang , Li Chunlei 
Published: December 2021

We propose a plasmonic waveguide comprising a single-layer graphene, a silica dielectric layer, and a silicon grating substrate to realize dual-channel slow surface plasmon polaritons. The dual-channel results from the introduction of two kinds of periodic structures with defects in the waveguide. According to the Bragg equation, we match the appropriate structure parameters to ensure the slow light dual-channel working around

(42 THz). The influence of the structure parameters on the slow light effect is discussed, and the largest value of the normalized delay bandwidth product (NDBP) is up to 7.38. Then, by shifting the gate voltage, obvious linear blueshift of the dual-channel is achieved. In this process, the slow light performance of the dual-channel exhibits good stability, and the average values of the NDBP are 4.5 and 4.4. Due to the flexible tunability, the waveguide may pave the way for the design of slow light devices.

Published: December 2021

Excimer lasers play a key role in deep ultraviolet lithography. To further study the voltage and energy features of the excimer laser and control it to work in a constant energy mode, a temporal convolutional neural network was designed to fabricate an excimer laser voltage–energy model. The proposed model uses the currently measured energy data to predict the subsequent output energy data. For the voltage–energy data that cannot be obtained, we simulated the initial energy data corresponding to the part of the voltage value based on the relationship between energy and voltage as the initial input of the model. The energy data of any voltage for the excimer laser at each moment were obtained. Finally, a continuous excimer laser voltage–energy model was established. The difference between the means of the measured and generated energy data is less than 0.5 mJ.
