    Most Christian universities support a traditional view of human sexuality. It is uncertain if they can survive with their religious identity intact, given the rapid increase in societal acceptance of same-sex marriage. The 2015 Obergefell v. Hodges decision legalizing same-sex marriage increases pressure to be more affirming. Thirty-four presidents at universities in the Council for Christian Colleges and Universities (CCCU) participated in a survey, and twelve were interviewed to explore their perceptions regarding that pressure and potential responses. The study was framed by institutional isomorphism theory, and data were analyzed using basic qualitative research methods. The results show that coercive isomorphism is the strongest mechanism, with current pressure to conform emanating from state and federal government. Regional variance is considerable as institutions in the South report little pressure while those in blue states like California report strong local pressure. It is experienced in actual or implied threats to remove student access to state and federal financial aid and eliminate tax-exempt status at universities that discriminate based on sexual orientation. Liberal voices within the Church, accrediting agencies, LGBT advocacy groups, and changing student values are other sources of pressure. Universities seek compromise solutions but are prepared to mount a legal challenge based on the Free Exercise Clause of the First Amendment. They are not prepared to deal with changing student values, the strongest long-term source of pressure. To withstand pressure to conform, Christian universities must craft a unified response; find alternative sources of funding; engage and educate their boards; and find a way to assure young people that it is possible to be kind and loving while holding non-affirming policies related to same-sex marriage

    Use of the Three-Spined Stickleback (Gasterosteus aculeatus) As a Sensitive in Vivo Test for Detection of Environmental Antiandrogens

    We have previously shown that exposure to exogenous androgens causes female sticklebacks (Gasterosteus aculeatus) to produce the glue protein, spiggin, in their kidneys. This protein can be quantified by an enzyme-linked immunosorbent assay developed and validated at the Centre for Environment, Fisheries and Aquaculture Science. Here we report the development of an in vivo test for the detection of environmental antiandrogens. The system involves the simultaneous exposure of female sticklebacks to 17α-methyltestosterone (a model androgen) at 500 ng/L and suspected environmental antiandrogens over a period of 21 days. The spiggin content of the kidneys is then measured, and any antiandrogenic activity is evaluated by comparing the spiggin levels of female fish exposed to antiandrogens to those of female fish exposed solely to the model androgen. The assay detects the antiandrogenic activity of flutamide, vinclozolin (both used at 250 μg/L), linuron (at 150 μg/L), and fenitrothion (at 15 and 150 μg/L). These results provide the first evidence of in vivo antiandrogenic activity of both linuron and fenitrothion in teleosts. Although there are other suggested fish species that could be used for this purpose, the stickleback is the only widely available species in which it is now possible to study both estrogenic and antiandrogenic end points in the same individual. Furthermore, the species is endemic and ubiquitous in Europe, and it possesses many ecological traits that make it better suited than other potential species for field research into endocrine disruption

    UKCP18 marine report

    Changes in global and regional sea level arise from a wide variety of geophysical processes that operate on different time and space scales (the sea level “jigsaw puzzle”). Global mean sea level (GMSL) rise occurs from thermal expansion of seawater and the addition of water to the ocean from the loss of land-based ice and water. Changes in land-based ice and water storage result in spatial patterns of regional sea level change through the associated impact on Earth’s gravity field and other effects. Local changes in seawater density and ocean circulation also give rise to a spatial pattern of change, which varies markedly among climate models, and is therefore highly uncertain. In addition, the ongoing response of the Earth system to the last deglaciation brings about a spatial pattern of regional sea level change across the UK that is dominated by the effect of vertical land motion. At local scales, the impacts of coastal sea level change typically arise primarily from extreme water level events. These deviations from the regional mean water level are often associated with storm surges and extreme wave conditions combined with the local tide. The UKCP18 sea level work focuses on 21st century projections of: (i) regional time-mean sea level; (ii) changes in surge extremes; (iii) potential changes in tide and surge characteristics; and (iv) changes in local wave climate. In addition, we present exploratory projections of regional time-mean sea level change out to 2300. All projections are rooted in, or traceable to, CMIP5 climate model simulations under the RCP climate change scenarios

    Standardization of Epidemiological Surveillance of Group A Streptococcal Impetigo

    Impetigo is a highly contagious bacterial infection of the superficial layer of skin. Impetigo is caused by group A Streptococcus (Strep A) and Staphylococcus aureus, alone or in combination, with the former predominating in many tropical climates. Strep A impetigo occurs mainly in early childhood, and the burden varies worldwide. It is an acute, self-limited disease, but many children experience frequent recurrences that make it a chronic illness in some endemic settings. We present a standardized surveillance protocol including case definitions for impetigo including both active (purulent, crusted) and resolving (flat, dry) phases and discuss the current tests used to detect Strep A among persons with impetigo. Case classifications that can be applied are detailed, including differentiating between incident (new) and prevalent (existing) cases of Strep A impetigo. The type of surveillance methodology depends on the burden of impetigo in the community. Active surveillance and laboratory confirmation is the preferred method for case detection, particularly in endemic settings. Participant eligibility, surveillance population and additional considerations for surveillance of impetigo, including examination of lesions, use of photographs to document lesions, and staff training requirements (including cultural awareness), are addressed. Finally, the core elements of case report forms for impetigo are presented and guidance for recording the course and severity of impetigo provided

    Longitudinal observation and decline of neutralizing antibody responses in the three months following SARS-CoV-2 infection in humans

    Get PDF
    Antibody responses to SARS-CoV-2 can be detected in most infected individuals 10–15 d after the onset of COVID-19 symptoms. However, due to the recent emergence of SARS-CoV-2 in the human population, it is not known how long antibody responses will be maintained or whether they will provide protection from reinfection. Using sequential serum samples collected up to 94 d post onset of symptoms (POS) from 65 individuals with real-time quantitative PCR-confirmed SARS-CoV-2 infection, we show seroconversion (immunoglobulin (Ig)M, IgA, IgG) in >95% of cases and neutralizing antibody responses when sampled beyond 8 d POS. We show that the kinetics of the neutralizing antibody response is typical of an acute viral infection, with declining neutralizing antibody titres observed after an initial peak, and that the magnitude of this peak is dependent on disease severity. Although some individuals with high peak infective dose (ID50 > 10,000) maintained neutralizing antibody titres >1,000 at >60 d POS, some with lower peak ID50 had neutralizing antibody titres approaching baseline within the follow-up period. A similar decline in neutralizing antibody titres was observed in a cohort of 31 seropositive healthcare workers. The present study has important implications when considering widespread serological testing and antibody protection against reinfection with SARS-CoV-2, and may suggest that vaccine boosters are required to provide long-lasting protection

    Deterministic Evolutionary Trajectories Influence Primary Tumor Growth: TRACERx Renal.

    Get PDF
    The evolutionary features of clear-cell renal cell carcinoma (ccRCC) have not been systematically studied to date. We analyzed 1,206 primary tumor regions from 101 patients recruited into the multi-center prospective study, TRACERx Renal. We observe up to 30 driver events per tumor and show that subclonal diversification is associated with known prognostic parameters. By resolving the patterns of driver event ordering, co-occurrence, and mutual exclusivity at clone level, we show the deterministic nature of clonal evolution. ccRCC can be grouped into seven evolutionary subtypes, ranging from tumors characterized by early fixation of multiple mutational and copy number drivers and rapid metastases to highly branched tumors with >10 subclonal drivers and extensive parallel evolution associated with attenuated progression. We identify genetic diversity and chromosomal complexity as determinants of patient outcome. Our insights reconcile the variable clinical behavior of ccRCC and suggest evolutionary potential as a biomarker for both intervention and surveillance

    Fc-Optimized Anti-CD25 Depletes Tumor-Infiltrating Regulatory T Cells and Synergizes with PD-1 Blockade to Eradicate Established Tumors

    CD25 is expressed at high levels on regulatory T (Treg) cells and was initially proposed as a target for cancer immunotherapy. However, anti-CD25 antibodies have displayed limited activity against established tumors. We demonstrated that CD25 expression is largely restricted to tumor-infiltrating Treg cells in mice and humans. While existing anti-CD25 antibodies were observed to deplete Treg cells in the periphery, upregulation of the inhibitory Fc gamma receptor (FcγR) IIb at the tumor site prevented intra-tumoral Treg cell depletion, which may underlie the lack of anti-tumor activity previously observed in pre-clinical models. Use of an anti-CD25 antibody with enhanced binding to activating FcγRs led to effective depletion of tumor-infiltrating Treg cells, increased effector to Treg cell ratios, and improved control of established tumors. Combination with anti-programmed cell death protein-1 antibodies promoted complete tumor rejection, demonstrating the relevance of CD25 as a therapeutic target and promising substrate for future combination approaches in immune-oncology
