Authors: Jenkins Jeffrey S. , Abatzoglou John T. , Peterson Brian A. 
Published: April 2023

Abstract
Wilderness visitation, particularly overnight use, is reactive to climate variability because backpackers face greater exposure to and dependence on environmental conditions. This study examines the effect that spring snowpack had on the timing and volume of permits issued for overnight use of the Yosemite Wilderness during peak and shoulder-season months (April–October) from 2002 to 2019. We categorize 1 April snowpack at Tuolumne Meadows into snow drought (<75%), high snowpack (>125%), and near-average snowpack (75%–125%). Results confirm wilderness-wide differences between snowpack categories, including change in spring overnight visitors (April–June: +20% snow drought and −28% high snowpack). Our findings confirm that snow drought allows for more access to high-elevation trailheads when seasonal roads are open earlier in spring (May–June: +74% Tioga Road and +81% Tuolumne Meadows). Mid- to high-elevation trailheads experience a sustained increase in use during high-snowpack years (June–October: +12% Yosemite Valley and Big Oak Flat; +15% Glacier Point Road and Wawona; +32% Hetch Hetchy) because a narrower seasonal access window leads to filled permit quotas in the high country and displaces use to lower-elevation trailheads. These findings have implications for wilderness stewards, including biophysical and experiential impacts on wilderness character from earlier and longer seasons, especially at higher elevation and in fragile alpine and subalpine areas, as snow drought in mountain-protected areas becomes more common. Recommendations to address greater early-season use and its attendant impacts include adaptively managing permits for different types of snowpack years, including potential changes in the number, timing, and destination of select trailhead quotas.

Authors: Li Shuo , Shi Yawen , Chen Tianzhen , Zhao Min 
Published: April 2023

Background: China has introduced a large number of national mental health policies over the past decade. However, few studies have touched on what changes the policies brought to the media. Aims: This study aimed to investigate the relationship between stigma reports, classifications of mental disorders (SMI: severe mental illness vs. CMD: common mental disorders) and sources of information (mental health professionals vs. non-mental health professionals) from 2011 to 2020 in China Daily, an established official media of China. Method: This study consists of policy review and media review. The policy review reviewed the media management content in Chinese national plans, policies, and laws on mental health from 2011 to 2020. China Daily news articles reporting mental illness-related topics were included in this study as the media material. After a two-step review, the eligible news articles were coded with a structured codebook. The proportion and frequency of stigma depiction of mental disorders, classifications of mental disorders and source of information were counted by year. Chi-test was undertaken to determine the relationship between stigma reports and different classifications of mental disorders and sources of information. An exploratory analysis was conducted to explore the changes in depiction around time points of policy publications. Results: The number of anti-stigmatizing articles increased significantly from 2011 to 2020. There is a statistical difference in the proportion of stigmatizing codes between articles featuring SMI and CMD (χ2 = 44.56, p < .001) and different sources of information (χ2 = 78.49, p < .001). And the statistical difference remained over the decade. Conclusion: The results of the research indicate that the media may have alleviated the problem of stigma. But the subtle stigmatization still exists, which needs joint efforts of the government and media.

Background: Glenoid bone loss is a critical factor in the management of anterior shoulder instability (ASI). Computed tomography (CT) is often considered the gold standard to evaluate glenoid bone loss, but it is associated with negative factors such as radiation. Thus, interest exists as to when orthopaedic surgeons need a CT scan to guide decision-making when treating ASI. Purpose: To determine whether information gained from a shoulder CT scan alters orthopaedic surgeons’ management plan for ASI and, secondarily, to determine whether surgeon- and patient-specific factors affect whether a CT scan changes treatment and which clinical factors are most important in surgical decision-making. Study Design: Cross-sectional study. Methods: A questionnaire composed of 24 ASI vignettes was administered to Herodicus Society members, American Shoulder and Elbow Surgeons Neer Circle members, and sports medicine fellowship–trained orthopaedic surgeons. Participants chose their recommended surgical treatment from the options of arthroscopic Bankart repair, open Bankart repair, bony reconstruction procedure, or other based on patient history, radiographs, and magnetic resonance imaging. Participants were then shown CT images and asked whether their treatment plan changed and, if not, whether the CT scan was not necessary or had reinforced their decision. Generalized linear mixed-effects logistic regression modeling was performed to assess the influence of vignette and respondent characteristics on treatment decisions. Results: A total of 74 orthopaedic surgeons completed the survey; 96% were fellowship trained (sports medicine, 50%; shoulder and elbow surgery, 41%), and 66% practiced in academic settings. CT imaging did not change the selected treatment strategy in 75.6% of responses. In cases when management did not change, surgeons reported that the CT scan reinforced their decision in 53.4% of responses and was not necessary for decision-making in 22.2% of responses. Decision-making was more likely to be changed after CT in male patients and those with off-track lesions. Conclusion: Information gained from a CT scan did not alter treatment decision-making in three-quarters of vignettes among surgeons experienced in the management of ASI. The finding that CT scans did alter the treatment plan in nearly a quarter of cases is not insignificant, and it appears that in patients with borderline glenoid track status and few other risk factors for recurrence after arthroscopic stabilization, CT imaging is more likely to change management.
Acetabular cup fixation with and without screws following primary total hip arthroplasty: migration evaluated by radiostereometric analysis

Published: April 2023

Background: Early cup migration after total hip arthroplasty (THA) is correlated to late revision due to aseptic loosening. However, the use of screws for increased cup stability remains unclear and debated. The purpose of this study is to assess acetabular migration between cups fixated with and without the use of screws. Methods: Patients underwent primary THA using either a direct anterior (DA) or a direct lateral (DL) approach. The DA surgeon routinely supplemented cup fixation with 1 or 2 screws while the DL surgeon used no screws. At 7 follow-up visits up to 2 years post operation, patients underwent radiostereometric analysis (RSA) imaging for implant migration tracking. The primary outcome was defined as proximal cup migration measured with model-based RSA. Results: 68 patients were assessed up to 2 years post operation, n = 43 received screws and n = 25 did not. The use of screws had a significant effect on cup migration ( p = 0.018). From 2 weeks to 2 years post operation, the total mean migration was 0.403 ± 0.681 mm and 0.129 ± 0.272 mm ( p = 0.319) for cups with and without screws, respectively. The number of screws used also had a significant impact, with cups fixated with 1 screw migrating more than cups fixated with 2 ( p = 0.013, mean difference 0.712 mm). Conclusions: Acetabular cups fixated with only 1 screw resulted in greater migration than cups with no screws or 2 screws, though the mean magnitude was well under the 1.0 mm threshold for unacceptable migration. However, 3 of the 24 patients who received only 1 screw exceeded the 1.0 mm threshold for unacceptable migration. Ultimately, the results of this study show that the use of 2 screws to supplement cup fixation can provide good implant stability that is equivalent to a secure press-fit component with no screws.

Published: April 2023

Background Telehealth is a rapidly growing modality for expanding healthcare access, especially in the post-COVID-19 era. However, telehealth requires high-quality broadband, thus making broadband a social determinant of health. The objective of this study was to evaluate the association between broadband access and telehealth utilization across the United States during the COVID-19 pandemic. Methods Using a cross-sectional, ecological study design, we merged county-level data on broadband capacity (Microsoft's Rural Broadband Initiative), telehealth utilization among Medicare Fee-for-Service beneficiaries from January through September 2020 (CareJourney), and county-level socioeconomic characteristics (Area Health Resources Files). Multivariable linear regression was used to estimate the association between broadband capacity, county-level characteristics, and telehealth utilization. Results Among the 3107 counties, those with the greatest broadband availability (quintile 5) had 47% higher telehealth utilization compared to counties with the least broadband availability (quintile 1). In the adjusted model, a 1 standard deviation (SD) increase in broadband access was associated with a 1.54 percentage point (pp) increase in telehealth utilization (P < 0.001). Rural county designation (−1.96 pp; P < 0.001) and 1 SD increases in average Medicare beneficiary age (−1.34 pp; P = 0.001), number of nursing home beds per 1000 individuals (−0.38 pp; P = 0.002), and proportion of Native Americans/Pacific Islanders (−0.59 pp; P < 0.001) were associated with decreased telehealth utilization. Conclusion The association between broadband access and telehealth utilization and the decreased telehealth utilization in rural areas highlight the importance of broadband access for healthcare access and the need to continue investing in broadband infrastructure to promote equitable healthcare access across populations.
Antecedents to Sexual Harassment of Women in Selected Male-Dominated Occupations: A Systematic Review
Authors: Riddle Kimbely , Heaton Karen 
Published: April 2023

Background: Approximately 50% of women in all workplaces experience sexual harassment. Women who work in male-dominated occupations may be more susceptible to sexual harassment than those who work in non-male-dominated occupations. Research on factors contributing to workplace sexual harassment in male-dominated occupations is limited. This paper reviews the known antecedents that put female workers at risk of sexual harassment in select male-dominated occupations and to identify gaps in the literature and opportunities for future occupational health nursing research. Methods: A search was conducted using PubMed, CINAHL, PsycINFO, and Web of Science. Included articles addressed sexual harassment of female workers in male-dominated occupations such as law enforcement, firefighting, truck driving, and construction. Results: The search yielded 25 relevant research articles. Antecedents to sexual harassment in the workplace included lower rank, shorter tenure, physicality of the job, job insecurity, negative relationships with peers and/or supervisors, treating women as outsiders, exaggerated gender differences, unequal gender ratios, and promotions based on gender. Common antecedents to sexual harassment in the workplace identified in the literature include organizational culture and gender composition. Conclusion/Application to Practice: Workplace sexual harassment of women is a problem in male-dominated occupations. Research is needed to better understand the organizational antecedents of sexual harassment in male-dominated occupations within community settings to prevent workplace sexual harassment.

Published: April 2023

AbstractTo enrich material types applied to additive manufacturing and enlarge application scope of additive manufacturing in conformal cooling tools, M2 high-speed steel specimens were fabricated by selective laser melting (SLM). Effects of SLM parameters on the microstructure and mechanical properties of M2 high-speed steel were investigated. The results showed that substrate temperature and energy density had significant influence on the densification process of materials and defects control. Models to evaluate the effect of substrate temperature and energy density on hardness were studied. The optimized process parameters, laser power, scan speed, scan distance, and substrate temperature, for fabricated M2 are 220 W, 960 mm/s, 0.06 mm, and 200 ℃, respectively. Based on this, the hardness and tensile strength reached 60 HRC and 1000 MPa, respectively. Interlaminar crack formation and suppression mechanism and the relationship between temperature gradient and thermal stress were illustrated. The inhibition effect of substrate temperature on the cracks generated by residual stresses was also explained. AM showed great application potential in the field of special conformal cooling cutting tool preparation.

Abstract
Background
Stone wool is an inorganic mineral insulation material increasingly used to reduce the climate impact of buildings. The acute and chronic ecotoxicological potential of stone wool eluates have been studied in a battery of standardized laboratory ecotoxicological tests. The experiments were conducted with stone wool test materials in fibrous and milled form, with and without the presence of organic binder. For the preparation of eluates, the OECD protocol on the transformation/dissolution of metals and metal compounds was applied. The resulting eluates were used in acute tests, i.e., bioluminescence test with Aliivibrio fischeri (DIN EN ISO 11348-1:2009), algae growth test with Desmodesmus subspicatus (OECD No. 201) and immobilization test with Daphnia magna (OECD No. 202), as well as chronic tests, i.e., the Daphnia magna reproduction test (OECD No. 211) and the nematode growth and reproduction test with Caenorhabditis elegans (ISO 10872:2010).

Results
While no acute or chronic ecotoxicological effects of the eluates were observed for fibrous stone wool material, the milled test materials showed some chronic effects on aquatic invertebrates. Depending on the test materials and concentrations of milled stone wool used in the eluate preparation, these chronic effects included significant stimulation or inhibition of daphnid reproduction and nematode growth. The chemical analysis conducted in parallel to the ecotoxicological assessment indicated no leaching of organic substances from the applied binder or mineral oils and no formation of nanoparticles by the milling of stone wool. Furthermore, ICP-MS and ICP-OES analysis of eighteen elements revealed that only aluminum and nickel could be quantified in the eluates, at concentrations of approximately 750 µg/L and 7 µg/L, respectively.

Conclusions
Based on the present ecotoxicological assessment, eluates from stone wool fibers cannot be considered as chemically hazardous to the aquatic environment. However, additional investigations of the ecotoxicological potential of the milled material and the environmental exposure of stone wool products are necessary for a complete evaluation of potentially negative effects of stone wool insulation materials.

Abstract
Backgroud
The single nucleotide polymorphisms (SNPs) and copy number variations (CNVs) are two major genomic variants, which play crucial roles in evolutionary and phenotypic diversity.

Results
In this study, we performed a comprehensive analysis to explore the genetic variations (SNPs and CNVs) of high sperm motility (HSM) and poor sperm motility (PSM) Simmental bulls using the high-coverage (25×) short-read next generation sequencing and single-molecule long reads sequencing data. A total of ~ 15 million SNPs and 2,944 CNV regions (CNVRs) were detected in Simmental bulls, and a set of positive selected genes (PSGs) and CNVRs were found to be overlapped with quantitative trait loci (QTLs) involving immunity, muscle development, reproduction, etc. In addition, we detected two new variants in LEPR, which may be related to the artificial breeding to improve important economic traits. Moreover, a set of genes and pathways functionally related to male fertility were identified. Remarkably, a CNV on SPAG16 (chr2:101,427,468 − 101,429,883) was completely deleted in all poor sperm motility (PSM) bulls and half of the bulls in high sperm motility (HSM), which may play a crucial role in the bull-fertility.

Conclusions
In conclusion, this study provides a valuable genetic variation resource for the cattle breeding and selection programs.

AbstractBackgroundGeranylgeranyl pyrophosphate synthase (GGPS) is a structural enzyme of the terpene biosynthesis pathway that is involved in regulating plant photosynthesis, growth and development, but this gene family has not been systematically studied in cotton.ResultsIn the current research, genome-wide identification was performed, and a total of 75 GGPS family members were found in four cotton species,Gossypium hirsutum,Gossypium barbadense,Gossypium arboreumandGossypium raimondii. The GGPS genes were divided into three subgroups by evolutionary analysis. Subcellular localization prediction showed that they were mainly located in chloroplasts and plastids. The closely related GGPS contains a similar gene structure and conserved motif, but some genes are quite different, resulting in functional differentiation. Chromosome location analysis, collinearity and selection pressure analysis showed that many fragment duplication events occurred in GGPS genes. Three-dimensional structure analysis and conservative sequence analysis showed that the members of the GGPS family contained a large number of α-helices and random crimps, and all contained two aspartic acid-rich domains, DDxxxxD and DDxxD (x is an arbitrary amino acid), suggesting its key role in function. Cis-regulatory element analysis showed that cotton GGPS may be involved in light response, abiotic stress and other processes. A GGPS gene was silenced successfully by virus-induced gene silencing (VIGS), and it was found that the chlorophyll content in cotton leaves decreased significantly, suggesting that the gene plays an important role in plant photosynthesis.ConclusionsIn total, 75 genes were identified in fourGossypiumspecies by a series of bioinformatics analysis. Gene silencing from GGPS members ofG. hirsutumrevealed that GGPS plays an important regulatory role in photosynthesis. This study provides a theoretical basis for the biological function of GGPS in cotton growth and development.

Published: April 2023

AbstractBackgroundGastrodia elata(tianma), a well-known medicinal orchid, is widely used to treat various kinds of diseases with its dried tuber. In recent years, new chromosome-level genomes ofG.elatahave been released in succession, which offer an enormous resource pool for understanding gene function. Previously we have constructed GelFAP for gene functional analysis ofG.elata. As genomes are updated and transcriptome data is accumulated, collection data in GelFAP cannot meet the need of researchers.ResultsBased on new chromosome-level genome and transcriptome data, we constructed co-expression network ofG. elata, and then we annotated genes by aligning with sequences from NR, TAIR, Uniprot and Swissprot database. GO (Gene Ontology) and KEGG (Kyoto Encylopaedia of Genes and Genomes) annotations were predicted by InterProScan and GhostKOALA software. Gene families were further predicted by iTAK (Plant Transcription factor and Protein kinase Identifier and Classifier), HMMER (hidden Markov models), InParanoid. Finally, we developed an improved platform for gene functional analysis inG. elata(GelFAP v2.0) by integrating new genome, transcriptome data and processed functional annotation. Several tools were also introduced to platform including BLAST (Basic Local Alignment Search Tool), GSEA (Gene Set Enrichment Analysis), Heatmap, JBrowse, Motif analysis and Sequence extraction. Based on this platform, we found that the flavonoid biosynthesis might be regulated by transcription factors (TFs) such as MYB, HB and NAC. We also tookC4HandGAFP4as examples to show the usage of our platform.ConclusionAn improved platform for gene functional analysis inG. elata(GelFAP v2.0,www.gzybioinformatics.cn/Gelv2) was constructed, which provides better genome data, more transcriptome resources and more analysis tools. The updated platform might be preferably benefit researchers to carry out gene functional research for their project.
