Published: February 2020

Introduction:
Recent studies in general surgery and internal medicine have shown that female physicians may have improved morbidity and mortality compared with their male counterparts. In the field of orthopaedic surgery, little is known about the influence of surgeon gender on patient complications. This study investigates patient complications after hip and knee arthroplasty based on the gender of the treating surgeon.

Methods:
Using a risk-adjusted outcomes database of 100% Medicare data from a third party, an analysis of outcomes after primary hip and knee arthroplasty based on surgeon gender was performed. This data set, which provided risk-adjusted complication rates for each surgeon performing at least 20 primary knee or hip arthroplasties from 2009 to 2013, was matched with publically available Medicare data sets to determine surgeon gender, year of graduation, area of practice, and surgical volume. Confounding variables were controlled for in multivariate analysis.

Results:
Of the 8,965 surgeons with identified gender, 187 (2.0%; 187 of 8,965) were identified as women and performed 21,216 arthroplasties (1.4%; 21,216 of 1,518,419). Overall, female surgeons averaged fewer arthroplasties (total knee arthroplasty: 87.0 versus 124.9 [P < 0.001]; total hip arthroplasty [THA]: 62.8 versus 78.8 [P = 0.02]) and were earlier in their practice (20.6 versus 25.0 years; P < 0.001) compared with their male counterparts. Male and female surgeons had similar adjusted complication rates for THA (2.78% versus 2.84%) and total knee arthroplasty (2.24% versus 2.26%). Multivariate analysis found that the predictors of increased complications were decreased surgeon volume, THA, increased surgeons' years in practice, and geographic region.

Discussion:
Overall, female orthopaedic surgeons performed fewer arthroplasties and were earlier in their career. This, however, did not a have a negative impact on their surgical outcomes. Rather, complication rates were dependent on surgeon volume, surgeon experience, and region.

Level of Evidence:

Published: February 2020

Background: Mosques are the most holy places in the eyes of Allah-Exalted and Glorified, and the religious mosque leaders (Khateebs) who read 15-20 minutes Khutbah prior to Friday Prayers have great knowledge in religion of Islam and are considered the peace-building leaders through delivering the pertinent Friday sermons around the world.
Objective: This online consenting cross-sectional survey explored the mental health awareness, perceptions, attitudes and practices of Khateebs of Riyadh region, Saudi Arabia.
Methods: This survey used 14-items self-designed culturally competitive questionnaire and sociodemographic proforma to tap religious mosque leaders’ knowledge, perceptions, practices and attitude towards mental health.
Results: Majority of mosque leaders were middle aged with higher education and extensive experience as a model of true interlocutor (Khateeb). Their knowledge and practices revealed were replete with religious and spiritual healing approaches but religious mosque leaders did not completely overlook the role of psychiatric medications and mental health professionals in the management of mentally ill persons. However, religious mosque leaders showed some negative attitudes towards patients with mental disorders, and recommended 10 corrective guides including integration of mosques and religious leaders into mental health system.
Conclusion: Despite mosque leader’s good mental health literacy, they need further training to plug certain loopholes traced in their mental health literacy. Researchers should conduct further similar research overcoming the caveats of this survey not only in Saudi Arabia but also globally in Muslim world.
Improving Cancer Immunotherapy with CRISPR‐Based Technology

Published: February 2020

AbstractThe rapidly evolving field of immunotherapy has attracted great attention in the field of cancer research and already revolutionized the clinical practice standard for treating cancer. Genetically engineered T cells expressing either T cell receptors or chimeric antigen receptors represent novel treatment modalities and are considered powerful weapons to fight cancer. The immune checkpoint blockade, which harnesses the negative control signaling behind the anti‐tumor immune response with therapeutic antibodies by blocking cytotoxic T lymphocyte‐associated protein 4 or the programmed cell death 1 pathways are another mainstream direction for cancer immunotherapy. In addition to cytotoxic T cells, other immune cell types such as nature killer cells and macrophages also possess the ability to eradicate cancer cells, which may serve as the basis to develop novel cancer immunotherapies. The advent of cutting‐edge genome editing technology, especially clustered regularly interspaced palindromic repeats (CRISPR)‐based tools, has greatly expedited many biomedical research areas, including cancer immunology and immunotherapy. In this review, the contribution of current CRISPR techniques to basic and translational cancer immunology research is discussed, and the future for cancer immunotherapy in the age of CRISPR is predicted.
Influence of farm size and insured type on crop insurance returns
Authors: Sharma Sankalp , Walters Cory G. 
Published: February 2020

AbstractIn this article, we empirically examine the impact of farm size and insured type on returns from crop insurance participation in four regions using unit‐level crop insurance contract data. Our quasi‐panel empirical model provides guidance on whether larger producers are riskier than smaller producers and whether cash producers are riskier than landlords. In our sample, we did not find evidence that large producers obtain higher returns from insurance participation than their smaller counterparts. In fact, we found evidence of the opposite that larger producers in Iowa and Nebraska receive less than their smaller counterparts. Our farm size results suggest that any legislation limiting crop insurance participation from large producers would negatively influence the insurance pool, driving up premiums and consequently administrative and operational subsidies and per‐acre premium subsidy dollars. We did find evidence that cash insured types get more back in insurance than landlords in both Montana and Oklahoma, suggesting the possibility of moral hazard in input usage. Our results also highlight spatial differences in crop insurance outcomes.

AbstractThe unique “green food” certification scheme in China, which is aimed to ensure environmental and product safety, has attracted increasing attention. In this study, using 398 household‐level survey data from kiwifruit growers in Xixia county of Henan Province, China, alongside a propensity score matching method, we examined the impact of “green food” certification scheme on economic and environmental effects. Our results showed that: (a) the “green food” certification program did not have significant environmental effect of sustainable production practices because kiwifruit growers did not significantly increase farmyard manure, reduce pesticide and chemical material inputs, except for employed labor inputs; (b) the certification did have significantly economic effect because certified growers received higher sale prices and had reasonable and even higher economic benefits. These findings suggest that the “green food” certification program did not significantly reduce the chemical material inputs, but it helped kiwifruit growers receive higher economic benefits. The “green food” certification program has not achieved its two major goals for kiwifruit production in China [EconLit citations: O13, O44, Q01].

PremiseNutrients, light, water, and temperature are key factors limiting the growth of individual plants in nature. Mutualistic interactions between plants and microbes often mediate resource limitation for both partners. In the mutualism between legumes and rhizobia, plants provide rhizobia with carbon in exchange for fixed nitrogen. Because partner quality in mutualisms is genotype‐dependent, within‐species genetic variation is expected to alter the responses of mutualists to changes in the resource environment. Here we ask whether partner quality variation in rhizobia mediates the response of host plants to changing light availability, and conversely, whether light alters the expression of partner quality variation.MethodsWe inoculated clover hosts with 11 strains of Rhizobium leguminosarum that differed in partner quality, grew plants under either ambient or low light conditions in the greenhouse, and measured plant growth, nodule traits, and foliar nutrient composition.ResultsLight availability and rhizobium inoculum interactively determined plant growth, and variation in rhizobium partner quality was more apparent in ambient light.ConclusionsOur results suggest that variation in the costs and benefits of rhizobium symbionts mediate host responses to light availability and that rhizobium strain variation might more important in higher‐light environments. Our work adds to a growing appreciation for the role of microbial intraspecific and interspecific diversity in mediating extended phenotypes in their hosts and suggests an important role for light availability in the ecology and evolution of legume–rhizobium symbiosis.

AbstractStudies on N2 activation and transformation by transition metal hydride complexes are of particular interest and importance. The synthesis and diverse transformations of a dinitrogen dititanium hydride complex bearing the rigid acridane‐based acriPNP‐pincer ligands {[(acriPNP)Ti]2(μ2‐η1:η2‐N2)(μ2‐H)2} are presented. This complex enabled N2 cleavage and hydrogenation even without additional H2 or other reducing agents. Furthermore, diverse transformations of the N2 unit with a variety of organometallic compounds such as ZnMe2, MgMe2, AlMe3, B(C6F5)3, PinBH, and PhSiH3 have been well established at the rigid acriPNP‐ligated dititanium framework, such as reversible bonding‐mode change between the end‐on and side‐on/end‐on fashions, diborylative N=N bond cleavage, the formal insertion of two dimethylaluminum species into the N=N bond, and the formal insertion of two silylene units into the N=N bond. This work has revealed many unprecedented aspects of dinitrogen reaction chemistry.

AbstractAlthough tremendous efforts have been devoted to understanding the origin of boosted charge storage on heteroatom‐doped carbons, none of the present studies has shown a whole landscape. Herein, by both experimental evidence and theoretical simulation, it is demonstrated that heteroatom doping not only results in a broadened operating voltage, but also successfully promotes the specific capacitance in aqueous supercapacitors. In particular, the electrolyte cations adsorbed on heteroatom‐doped carbon can effectively inhibit hydrogen evolution reaction, a key step of water decomposition during the charging process, which broadens the voltage window of aqueous electrolytes even beyond the thermodynamic limit of water (1.23 V). Furthermore, the reduced adsorption energy of heteroatom‐doped carbon consequently leads to more stored cations on the heteroatom‐doped carbon surface, thus yielding a boosted charge storage performance.

Published: February 2020

AbstractIn the life system, the biointerface plays an important role in cell adsorption, platelet adsorption and activation. Therefore, the study of protein adsorption on the biointerface is of great significance for understanding life phenomena and treatment in vitro. In this paper, a chiral biointerface was constructed by the virtue of host‐guest interaction between a water‐soluble pillar[5]arene (WP5) and phenethylamine (PEA) over a gold surface for adsorption of lysozyme proteins. From the experimental results it was identified that the host‐guest biointerface has a high adsorption capacity and strong chiral selectivity. Furthermotre, it was identified that the host‐guest interaction plays the decisive role in the enhancement of chirality of the interface, which was much beneficial for increasing protein adsorption and amplifying the capacity of chiral discrimination. Therefore, this work provides a new idea for the construction of biointerface materials with high protein adsorption capacity and high chiral selectivity through supramolecular interaction, which will have potential applications in the fields of biosensors, biocatalysts, biomaterials.

Published: February 2020

AbstractBackgroundTwo RCTs (AVOD and DIABOLO) demonstrated no difference in recovery or adverse outcomes when antibiotics for acute uncomplicated diverticulitis were omitted. Both trials showed non-significantly higher rates of complicated diverticulitis and surgery in the non-antibiotic groups. This meta-analysis of individual-patient data aimed to explore adverse outcomes and identify patients at risk who may benefit from antibiotic treatment.MethodsIndividual-patient data from those with uncomplicated diverticulitis from two RCTs were pooled. Risk factors for adverse outcomes and the effect of observational management were assessed using logistic regression analyses. P &lt; 0·025 was considered statistically significant owing to multiple testing adjustment.ResultsIn total, 545 patients in the observational group and 564 in the antibiotics group were included. No statistical differences were found in 1-year follow-up rates of ongoing diverticulitis (7·2 versus 5·0 per cent in observation versus antibiotics groups respectively; P = 0·062), recurrent diverticulitis (8·6 versus 9·6 per cent; P = 0·610), complicated diverticulitis (4·0 versus 2·1 per cent; P = 0·079) and sigmoid resection (5·0 versus 2·5 per cent; P = 0·214). An initial pain score greater than 7, white blood cell count exceeding 13·5 × 109/l and previous diverticulitis at presentation were risk factors for adverse outcomes. Antibiotic treatment did not prevent adverse outcomes in patients at high risk of adverse events.ConclusionObservational management of acute uncomplicated diverticulitis is safe. Some statistical uncertainty remains, depending on the thresholds of clinical relevance, owing to small differences, but no subgroup that would benefit from antibiotic treatment was apparent.

AbstractIt is challenging to design metal catalysts for in situ transformation of endogenous biomolecules with good performance inside living cells. Herein, we report a multifunctional metal catalyst, ruthenium‐coordinated oligo(p‐phenylenevinylene) (OPV‐Ru), for intracellular catalysis of transfer hydrogenation of nicotinamide adenine dinucleotide (NAD+) to its reduced format (NADH). Owing to its amphiphilic characteristic, OPV‐Ru possesses good self‐assembly capability in water to form nanoparticles through hydrophobic interaction and π–π stacking, and numerous positive charges on the surface of nanoparticles displayed a strong electrostatic interaction with negatively charged substrate molecules, creating a local microenvironment for enhancing the catalysis efficiency in comparison to dispersed catalytic center molecule (TOF value was enhanced by about 15 fold). OPV‐Ru could selectively accumulate in the mitochondria of living cells. Benefiting from its inherent fluorescence, the dynamic distribution in cells and uptake behavior of OPV‐Ru could be visualized under fluorescence microscopy. This work represents the first demonstration of a multifunctional organometallic complex catalyzing natural hydrogenation transformation in specific subcellular compartments of living cells with excellent performance, fluorescent imaging ability, specific mitochondria targeting and good chemoselectivity with high catalysis efficiency.
