Degendering Parents on Birth Certificates.

Birth certificates typically designate parents as "mothers" or "fathers," although some US states offer nongendered designations. The authors argue that gendered characterizations offer scant legal or moral value and that states should move to degender parental status on birth certificates but retain that information in registrations of birth. Registrations of birth identify the person giving birth to a child, when, and where, and they report demographic and health information useful for civic and public health purposes. Birth certificates typically report a child's name, sex, date and location of birth, and parentage so far as known. As documents establishing parents' standing in relation to children and vice versa, as well as age and presumptive citizenship, birth certificates add no legal or moral value by gendering parents. Gendering parents on birth certificates obliges the state to rely on exclusionary criteria of "mother" and "father." By contrast, degendering parental status withdraws the need for such criteria and confers benefits on people with transgender and nonbinary identities, as well as undercutting any problematic presumption that parents have responsibilities to their children qua mother or qua father.

Identification and quantification of 11 airborne biochemicals emitted by the brown recluse and another primitive hunting spider using headspace solid-phase microextraction-GC/MS.

Loxosceles reclusa, or brown recluse spider, is a harmful household spider whose habitat extends throughout the Midwest in the USA and other regions in the world. The pheromones and other biomolecules that facilitate signaling for brown recluses and other spider species are poorly understood. A rapid and sensitive method is needed to analyze airborne spider signaling biomolecules to better understand the structure and function of these biochemicals in order to control the population of the spiders. In this study, we developed a novel headspace solid-phase microextraction (HS-SPME)-GC/MS method to analyze potential pheromones and biomolecules emitted by the brown recluse spider. The method is highly selective and sensitive for biomolecule identification and quantification from a single live spider. Using this novel non-destructive HS-SPME-GC/MS technique, we identified 11 airborne biomolecules, including 4-methylquinazoline, dimethyl sulfone, 2-methylpropanoic acid, butanoic acid, hexanal, 3-methylbutanoic acid, 2-methylbutanoic acid, 2,4-dimethylbenzaldehyde, 2-phenoxyethanol, and citral (contains both isomers of neral and geranial). Some of these airborne biomolecules were also reported as semiochemicals associated with biological functions of other spiders and insects. The method was also applied to study the airborne biochemicals of Plectreurys tristis, another primitive hunting spider with a poor web, enabling quantitation of the same compounds and demonstrating a difference in signaling molecule concentrations between the two species. This method has potential application in the study of pheromones and biological signaling in other species, which allows for the possibility of utilizing attractant or deterrent functions to limit household populations of harmful species.

Dying well in nursing homes during COVID-19 and beyond: The need for a relational and familial ethic.

This paper applies a relational and familial ethic to address concerns relating to nursing home deaths and advance care planning during Covid-19 and beyond. The deaths of our elderly in nursing homes during this pandemic have been made more complicated by the restriction of visitors even at the end of life, a time when families would normally be present. While we must be vigilant about preventing unnecessary deaths caused by coronavirus outbreaks in nursing homes, some deaths of our elders are inevitable. Thus, it is essential that advanced care planning occurs in a way that upholds the familial and relational aspects of elders' lives that often matter to them the most. We invoke concepts from feminist ethicists like Hilde Lindemann and Eva Kittay and introduce Avery Weisman and Thomas Hackett's concept of "appropriate death" to suggest better ways of planning for those deaths of our elderly that cannot be avoided. Our hope is to allow for deaths that are as meaningful as possible for both the elderly and the family members who survive them.

Gestation as mothering.

Some commentators maintain that gestational surrogates are not 'mothers' in a way capable of grounding a claim to motherhood. These commentators find that the practices that constitute motherhood do not extend to gestational surrogates. We argue that gestational surrogates should be construed as mothers of the children they bear, even if they fully intend to surrender those children at birth to the care of others. These women stand in a certain relationship to the expected children: they live in changed moral circumstances by reason of their pregnancy, and they engage in the practices said to define motherhood in the post-birth context. By contrast, ovum donors and embryo donors are not similarly 'mothers' because they do not find themselves involved in these circumstances. Not all women involved in three-parent in vitro fertilization qualify as mothers either. Given this analysis of mothering, we note that transmen who gestate children are engaged in mothering activity even if they otherwise function as a father to those children. By itself, this defence of the maternity of gestational surrogates does not confer moral title to the children they bear; gestation would not by itself override the contractual arrangements gestational surrogates have made regarding the disposition of their children. This interpretation of gestational surrogates as mothers does, however, undercut cultural understandings of these women as mere 'vessels', devoid of entitlement to respect as persons and parents. We also consider the meaning of mothering for 'brain-dead' women kept alive to give birth and for the prospect of extracorporeal gestation.

Sedation and Analgesia for Adult Outpatient Burn Dressing Change: A Survey of American Burn Association Centers.

The management of pain and sedation during burn dressing change is challenging. Previous reviews and studies have identified wide variability in such practices in hospitalized burn patients. This survey-based study aimed to determine the most commonly utilized sedation and analgesia practices in adult burn patients treated in the outpatient setting. The goal was to identify opportunities for improvement and to assist burn centers in optimizing sedation procedures. A 23-question survey was sent to members of the American Burn Association. Nonpharmacological interventions including music, television, games, and virtual reality were used by 68% of survey respondents. Eighty-one percent reported premedicating with oral opioids, 32% with intravenous opioids, and 45% with anxiolytics. Fifty-nine percentage of respondents indicated that the initial medication regimen for outpatient dressing changes consisted of the patient's existing oral pain medications. Forty-three percent indicated that there were no additional options if this regimen provided inadequate analgesia. Fifty-six percentage of respondents felt that pain during dressing change was adequately controlled 75% to 100% of the time, and 32% felt it was adequately controlled 50% to 75% of the time. Nitrous oxide was used by 8%. Anesthesia providers and an acute pain service are available in a minority of cases (13.7% and 28%, respectively) and are rarely consulted. Procedural burn pain remains significantly undertreated in the outpatient setting and the approach to treatment is variable among burn centers in the United States. Such variation likely represents an opportunity for identifying and implementing optimal practices and developing guidelines for burn pain management in the outpatient setting.

Seasonal Variation of Water Quality in Unregulated Domestic Wells.

In the United States (U.S.), up to 14% of the population depend on private wells as their primary drinking water source. The U.S. government does not regulate contaminants in private wells. The goals of this study were to investigate the quality of drinking water from unregulated private wells within one mile (1.6 kilometers) of an effluent-dominated river in the arid Southwest, determine differences in contaminant levels between wet and dry seasons, and identify contributions from human sources by specifically measuring man-made organic contaminants (perfluorooctanoic acid (PFOA), perfluorooctane sulfate (PFOS), and sucralose). Samples were collected during two dry seasons and two wet seasons over the course of two years and analyzed for microbial (Escherichia coli), inorganic (arsenic, cadmium, chromium, copper, lead, mercury, nitrate), and synthetic organic (PFOA, PFOS, and sucralose) contaminants. Arsenic, nitrate, and Escherichia coli concentrations exceeded their respective regulatory levels of 0.01 mg/L, 10 mg/L, and 1 colony forming unit (CFU)/100 mL, respectively. The measured concentrations of PFOA and PFOS exceeded the respective Public Health Advisory level. Arsenic, PFOA, PFOS, and sucralose were significantly higher during the dry seasons, whereas E. coli was higher during the wet seasons. While some contaminants were correlated (e.g., As and Hg ρ = 0.87; PFOA and PFOS ρ = 0.45), the lack of correlation between different contaminant types indicates that they may arise from different sources. Multi-faceted interventions are needed to reduce exposure to drinking water above health-based guidelines.

So not mothers: responsibility for surrogate orphans.

The law ordinarily recognises the woman who gives birth as the mother of a child, but in certain jurisdictions, it will recognise the commissioning couple as the legal parents of a child born to a commercial surrogate. Some commissioning parents have, however, effectively abandoned the children they commission, and in such cases, commercial surrogates may find themselves facing unexpected maternal responsibility for children they had fully intended to give up. Any assumption that commercial surrogates ought to assume maternal responsibility for abandoned children runs contrary to the moral suppositions that typically govern contract surrogacy, in particular, assumptions that gestational carriers are not 'mothers' in any morally significant sense. In general, commercial gestational surrogates are almost entirely conceptualised as 'vessels'. In a moral sense, it is deeply inconsistent to expect commercial surrogates to assume maternal responsibility simply because commissioning parents abandon children for one reason or another. We identify several instances of child abandonment and discuss their implications with regard to the moral conceptualisation of commercial gestational surrogates. We conclude that if gestational surrogates are to remain conceptualised as mere vessels, they should not be expected to assume responsibility for children abandoned by commissioning parents, not even the limited responsibility of giving them up for adoption or surrendering them to the state.

Home-based care, technology, and the maintenance of selves.

In this paper, I will argue that there is a deep connection between home-based care, technology, and the self. Providing the means for persons (especially older persons) to receive care at home is not merely a kindness that respects their preference to be at home: it is an important means of extending their selfhood and respecting the unique selves that they are. Home-based technologies like telemedicine and robotic care may certainly be useful tools in providing care for persons at home, but they also have important implications for sustaining selfhood in ways that are of value to individuals and those who care for them. I will argue, by appealing to Hilde Lindemann's notion of "holding" persons' identities in place, that technological interventions are not only useful tools for improving and sustaining health and good care at home, but that they may also help to extend our personal identities and relational capacities in ways that are practically and ethically good. Because of these important goods, I will claim that there is a prima facie moral duty to do this "holding" work and that it is best done by family members and loved ones who are well suited to the job because of their history and relationship with the individual that needs to be "held" in place.

Variation in Arabidopsis flowering time associated with cis-regulatory variation in CONSTANS.

The onset of flowering, the change from vegetative to reproductive development, is a major life history transition in flowering plants. Recent work suggests that mutations in cis-regulatory mutations should play critical roles in the evolution of this (as well as other) important adaptive traits, but thus far there has been little evidence that directly links regulatory mutations to evolutionary change at the species level. While several genes have previously been shown to affect natural variation in flowering time in Arabidopsis thaliana, most either show protein-coding changes and/or are found at low frequency (<5%). Here we identify and characterize natural variation in the cis-regulatory sequence in the transcription factor CONSTANS that underlies flowering time diversity in Arabidopsis. Mutation in this regulatory motif evolved recently and has spread to high frequency in Arabidopsis natural accessions, suggesting a role for these cis-regulatory changes in adaptive variation of flowering time.

A survey of the trans-regulatory landscape for Drosophila melanogaster abdominal pigmentation.

Trait development results from the collaboration of genes interconnected in hierarchical networks that control which genes are activated during the progression of development. While networks are understood to change over developmental time, the alterations that occur over evolutionary times are much less clear. A multitude of transcription factors and a far greater number of linkages between transcription factors and cis-regulatory elements (CREs) have been found to structure well-characterized networks, but the best understood networks control traits that are deeply conserved. Fruit fly abdominal pigmentation may represent an optimal setting to study network evolution, as this trait diversified over short evolutionary time spans. However, the current understanding of the underlying network includes a small set of transcription factor genes. Here, we greatly expand this network through an RNAi-screen of 558 transcription factors. We identified 28 genes, including previously implicated abd-A, Abd-B, bab1, bab2, dsx, exd, hth, and jing, as well as 20 novel factors with uncharacterized roles in pigmentation development. These include genes which promote pigmentation, suppress pigmentation, and some that have either male- or female-limited effects. We show that many of these transcription factors control the reciprocal expression of two key pigmentation enzymes, whereas a subset controls the expression of key factors in a female-specific circuit. We found the pupal Abd-A expression pattern was conserved between species with divergent pigmentation, indicating diversity resulted from changes to other loci. Collectively, these results reveal a greater complexity of the pigmentation network, presenting numerous opportunities to map transcription factor-CRE interactions that structure trait development and numerous candidate loci to investigate as potential targets of evolution.

Trap design for the brown recluse spider, Loxosceles reclusa.

While there are limited options for chemical-free Arachnid pest control, glue-traps are one suitable alternative to pesticides. The effectiveness of several three-dimensional glue-trap shapes for trapping the brown recluse spider, Loxosceles reclusa Gertsch and Mulaik (Araneae: Sicariidae), was investigated using four novel glue-trap shape designs, which were compared to an existing design currently on the market. These four novel and one standard shape designs were tested using pairwise comparisons. The most preferred trap design was a flat glue-trap with no covering. Although this type of trap was most efficient for capturing L. reclusa, it can pose risks in homes with children and pets for obvious reasons. Among the traps with coverings, the vertical strut trap was most preferred by the spiders, and should perhaps be the trap of choice for homeowners with children and pets.

Discrete event simulation for healthcare organizations: a tool for decision making.

Healthcare organizations face challenges in efficiently accommodating increased patient demand with limited resources and capacity. The modern reimbursement environment prioritizes the maximization of operational efficiency and the reduction of unnecessary costs (i.e., waste) while maintaining or improving quality. As healthcare organizations adapt, significant pressures are placed on leaders to make difficult operational and budgetary decisions. In lieu of hard data, decision makers often base these decisions on subjective information. Discrete event simulation (DES), a computerized method of imitating the operation of a real-world system (e.g., healthcare delivery facility) over time, can provide decision makers with an evidence-based tool to develop and objectively vet operational solutions prior to implementation. DES in healthcare commonly focuses on (1) improving patient flow, (2) managing bed capacity, (3) scheduling staff, (4) managing patient admission and scheduling procedures, and (5) using ancillary resources (e.g., labs, pharmacies). This article describes applicable scenarios, outlines DES concepts, and describes the steps required for development. An original DES model developed to examine crowding and patient flow for staffing decision making at an urban academic emergency department serves as a practical example.

Outcomes of nasal bridling to secure enteral tubes in burn patients.

BACKGROUND: Reliable securement of nasally inserted enteral tubes is a problem in patients with facial burns that make use of traditional adhesive tape ineffective. OBJECTIVE: To implement the nasal bridle as a way to decrease inadvertent removal of nasally inserted enteral tubes and improve subsequent patient outcomes. METHODS: The nasal bridle was implemented in the burn unit of the University of Kansas Hospital, Kansas City, Kansas, as a quality improvement project. Outcomes for the calendar year 2010 were measured in patients treated before use of the bridle (prebridle control group) and in patients for whom the bridle was used. The groups were compared on measures of tube insertions per tube day, abdominal radiographs per tube day, and a number of complications. RESULTS: A total of 50 patients were studied: 33 in the control group and 17 in the bridle group. Baseline characteristics of age and sex did not differ between the groups. The bridle group had significantly fewer tube insertions and abdominal radiographs per tube day than the control group. Although complications were generally less common in the bridle group, the differences were not statistically significant. CONCLUSIONS: In burn patients, use of a nasal bridle to secure nasally inserted tubes had clinical advantages over securement with traditional adhesive tape.

Designed to fail: how computer simulation can detect fundamental flaws in clinic flow.

Discrete-event simulation can be used as an effective tool for healthcare administrators to "test" various operational decisions. The recent growth in hospital outpatient volumes and a constrained financial environment make discrete-event simulation a cost-effective way to diagnose inefficiency and create and test strategies for improvement. This study shows how discrete-event simulation was used in an adult medicine clinic within a large, tertiary care, academic medical center. Simulation creation steps are discussed, including information gathering, process mapping, data collection, model creation, and results. Results of the simulation indicated that system bottle-necks were present in the medication administration and check-out steps of the clinic process. The simulation predicted that matching resources to excessive demand at appropriate times for these bottleneck steps would reduce patients' mean time in the system (i.e., visit time) from 124.3 (s.d. +/- 65.7) minutes to 87.0 (s.d. +/- 36.4) minutes. Although other factors may affect real-world operations of a clinic, discrete-event simulation allows healthcare administrators and clinic operational decision makers to observe the effects of changing staffing and resource allocations on patient wait and throughput time. Discrete-event simulation is not a cure-all for clinic throughput problems, but can be a strong tool to provide evidentiary guidance for clinic operational redesign.

Postinjury employment as a surrogate for functional outcomes: a quality indicator for trauma systems.

Return to work may be easily monitored as a surrogate of long-term functional outcome for benchmarking and performance improvement of trauma systems. We hypothesized that employment rates among survivors of traumatic brain injury (TBI) decrease following injury and remain depressed for an extended period of time. Data were obtained from a statewide surveillance system of 3522 TBI patients (aged >15 years) who were discharged alive from acute care hospitals and followed yearly using telephone interviews (1996-1999). The study population consisted of patients with severe TBI (head abbreviated injury score 3, 4, or 5) and complete follow-up for 3 years postinjury (n = 572). Patients were mostly young males (43 ± 19 years, 65% male) with blunt TBI (92%). The preinjury employment rate was 67%, which declined to 52% (P < 0.001) in the first year and slowly rose in subsequent years but never reached the preinjury level (54% in year 2, P < 0.001; 57% in year 3, P = 0.001). Increasing severity of TBI was associated with a lower employment rate. Patients who remained employed worked the same number of hours as they did before the injury (47.8 ± 10.5 hours). Female employment rates rose similar to rates for males. However, women who were employed full-time before TBI were more likely to work part-time after TBI than men (50% vs 24%, P < 0.001). In conclusion, survivors of severe injury do not attain preinjury employment levels for several years. Once validated in other studies, postinjury employment may be used as an indicator to monitor functional outcomes in trauma registries.

Care ethics and the global practice of commercial surrogacy.

This essay will focus on the moral issues relating to surrogacy in the global context, and will critique the liberal arguments that have been offered in support of it. Liberal arguments hold sway concerning reproductive arrangements made between commissioning couples from wealthy nations and the surrogates from socioeconomically weak backgrounds that they hire to do their reproductive labor. My argument in this paper is motivated by a concern for controlling harms by putting the practice of globalized commercial surrogacy into the context of care ethics. As I will argue, the unstable situations into which children of global surrogacy arrangements are born is symbolic of the crisis of care that the practice raises. Using the Baby Manji case as my touch point, I will suggest that liberalism cannot address the harms experienced by Manji and children like her who are created through the global practice of assisted reproductive technology. I will argue that, if commissioning couples consider their proposed surrogacy contracts from a care ethics point of view, they will begin to think relationally about their actions, considering the practice from an ethical lens, not just an economic or contractual one.

More operations, more deaths? Relationship between operative intervention rates and risk-adjusted mortality at trauma centers.

INTRODUCTION: The Trauma Quality Improvement Project has demonstrated significant variations in risk-adjusted mortality rates across the designated trauma centers. It is not known whether the outcome differences are related to provider-level clinical decision making. We hypothesized that centers with good outcomes undertake critical operative interventions aggressively, thereby avoiding complications and deaths. METHODS: The previously validated Trauma Quality Improvement Project risk-adjustment algorithm was used to measure observed-to-expected mortality rates (O/E with 90% confidence intervals [CI]) for 152 Level I and II trauma centers participating in the National Trauma Data Bank (version 7.0). Adult patients (>or=16 years) with at least one severe injury (Abbreviated Injury Scale score >or=3) were included (N = 135,654). Operative intervention rates for solid organ injuries (spleen, liver, and kidney) were compared between the centers classified as high mortality (O/E with CI > 1, n = 35 centers) versus low mortality (O/E with CI < 1, n = 37 centers) using nonparametric tests. RESULTS: Low- and high-mortality trauma centers were similar in designation level, hospital and intensive care unit beds, teaching status, and number of trauma, orthopedic, and neurosurgeons. Despite a similar incidence and severity of solid organ injuries, low-mortality centers were less likely to undertake operative interventions. CONCLUSION: Trauma centers with higher risk-adjusted mortality rates are more likely to undertake operative interventions for solid organ injuries. Hence, there is a need to focus quality improvement efforts on medical decision-making and perioperative processes of care.

Centers for Medicare and Medicaid services quality indicators do not correlate with risk-adjusted mortality at trauma centers.

OBJECTIVES: The Centers for Medicare and Medicaid Services (CMS) publicly reports hospital compliance with evidence-based processes of care as quality indicators. We hypothesized that compliance with CMS quality indicators would correlate with risk-adjusted mortality rates in trauma patients. METHODS: A previously validated risk-adjustment algorithm was used to measure observed-to-expected mortality ratios (O/E with 95% confidence interval) for Level I and II trauma centers using the National Trauma Data Bank data. Adult patients (>or=16 years) with at least one severe injury (Abbreviated Injury Score >or=3) were included (127,819 patients). Compliance with CMS quality indicators in four domains was obtained from Hospital Compare website: acute myocardial infarction (8 processes), congestive heart failure (4 processes), pneumonia (7 processes), surgical infections (3 processes). For each domain, a single composite score was calculated for each hospital. The relationship between O/E ratios and CMS quality indicators was explored using nonparametric tests. RESULTS: There was no relationship between compliance with CMS quality indicators and risk-adjusted outcomes of trauma patients. CONCLUSIONS: CMS quality indicators do not correlate with risk-adjusted mortality rates in trauma patients. Hence, there is a need to develop new trauma-specific process of care quality indicators to evaluate and improve quality of care in trauma centers.
