Abstract
Accurate measurement of abdominal aortic aneurysms is necessary to predict rupture risk and, more recently, to follow aneurysm sac behavior following endovascular repair. Up until this point, aneurysm diameter has been the most common measurement utilized for these purposes. Although aneurysm diameter is predictive of rupture, accurate measurement is hindered by such factors as aortic tortuosity and interobserver variability, and it does not account for variations in morphology such as saccular aneurysms. Additionally, decreases in aneurysm diameter do not completely describe the somewhat complex remodeling seen following endovascular repair of aortic aneurysms. Measurement of aneurysm volume has the advantage of describing aneurysm morphology in a multidimensional fashion, but it has not been readily available or easily measured until recently. This has changed with the introduction of commercially available software tools that permit quicker and easier to perform volume measurements. Whether it is time for volume to replace, or compliment, diameter is the subject of the current debate.

Abstract
Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality in the United States, and worldwide. Recognition of PPH is challenging, but once hemorrhage is recognized, management needs to focus on achieving adequate uterine tone and maintaining maternal hemodynamic stability. There have been several advances in the management of postpartum hemorrhage, many of which can be implemented at the labor and delivery unit level.There have been many advances in the understanding of at-risk parturients, and the use of hemorrhage protocols and safety bundles have been shown to improve patient outcomes. There are many new advances in transfusion management (e.g. fibrinogen concentrate, prothrombin complex concentrate, tranexamic acid) that can compliment traditional component therapy. Consideration should be given to transferring women at high risk for complications (e.g. invasive placentation) to a higher level facility for delivery.Although postpartum hemorrhage itself may not be preventable, early identification of blood loss, and mobilization of resources may prevent adverse outcomes. Multidisciplinary planning at the system level, ensuring that hemorrhage protocols exist, as well as for management of high-risk patients is important for improving patient outcomes.

Abstract
Lencucha and Thow tackle the enormous public health challenge of developing non-communicable disease (NCD) policy coherence within a world structured and ruled by neoliberalism. Their work compliments scholarship on other causal mechanisms, including the commercial determinants of health, that have contributed to creating the risk commodity environment and barriers to NCD prevention policy coherence. However, there remain significant gaps in the understanding of how these causal mechanisms interact within a whole system. As such, public health researchers' suggestions for how to effectively prevent NCDs through addressing the risk commodity environment tend to remain fragmented, incomplete and piecemeal. We suggest this is, in part, because conventional policy analysis methods tend to be reductionist, considering causal mechanisms in relative isolation and conceptualizing them as linear chains of cause and effect. This commentary discusses how a systems thinking approach offers methods that could help with better understanding the risk commodity environment problem, identifying a more comprehensive set of effective solutions across sectors and its utility more broadly for gaining insight into how to ensure recommended solutions are translated into policy, including though transformation at the paradigmatic level.

Abstract
Perfluoroalkyl substances (PFAS) are ubiquitous and persistent environmental contaminants, yet knowledge of their biological effects and mechanisms of action is limited. The highest aqueous PFAS concentrations are found in areas where bacteria are relied upon for functions such as nutrient cycling and contaminant degradation, including fire-training areas, wastewater treatment plants, and landfill leachates. This research sought to elucidate one of the mechanisms of action of PFAS by studying their uptake by bacteria and partitioning into model phospholipid bilayer membranes. PFAS partitioned into bacteria as well as model membranes (phospholipid liposomes and bilayers). The extent of incorporation into model membranes and bacteria was positively correlated to the number of fluorinated carbons. Furthermore, incorporation was greater for perfluorinated sulfonates than for perfluorinated carboxylates. Changes in zeta potential were observed in liposomes but not bacteria, consistent with PFAS being incorporated into the phospholipid bilayer membrane. Complementary to these results, PFAS were also found to alter the gel-to-fluid phase transition temperature of phospholipid bilayers, demonstrating that PFAS affected lateral phospholipid interactions. This investigation compliments other studies showing that sulfonated PFAS and PFAS with more than seven fluorinated carbons have a higher potential to accumulate within biota than carboxylated and shorter-chain PFAS.

Abstract
Individuals with developmental disabilities, such as autism spectrum disorder, typically exhibit conversation skill deficits, with two prevailing deficits including giving and accepting compliments. The current study used an individualized approach to assess and teach accepting and giving compliments specific to performance, possession, and appearance with three adolescents and young adults with developmental disabilities. We taught these skills using behavioral skills training and prompting during conversations utilizing a multiple-baseline design across participants. We also observed generalization and treatment extension of the participants' skills in conversations with adults not associated with teaching and in the absence of any teaching procedures. The results support the efficacy of the procedures used toward improving giving and accepting compliments within the context of a conversation. We discuss considerations to improve the social acceptability of and refinements to the teaching procedures and acquired skills.

Abstract
Pulmonary wall isolation (PWI) is increasingly used as an adjunctive lesion set to compliment pulmonary vein isolation (PVI), especially in patients with persistent atrial fibrillation (AF). The objective was to compare outcomes of catheter ablation in patients with persistent AF undergoing PVI with and without adjunctive PWI.We performed a retrospective study of 558 patients who underwent de novo and repeat ablation for persistent AF. Subjects were matched using propensity score adjustments. Outcomes were freedom from recurrent atrial arrhythmia and adverse events.Among 558 patients who underwent ablation for persistent AF, 78 (14%) underwent PVI + PWI, 255 (46%) underwent PVI, and 225 (40%) underwent PVI + linear ablation. Stratified logistic regression analysis with propensity matching revealed higher odds of recurrent arrhythmia with PVI + PWI when compared to PVI (odds ratio [OR] 2.25, 95% CI 1.08-4.69, P = .030) and when compared to PVI + linear (OR 2.31, 95% CI 1.01-5.28, P = .048). Within the PVI + PWI group, 57.7% of subjects were in normal sinus rhythm at 6 months compared to 73.9% and 72.2% in PVI and PVI + linear groups, respectively. Adverse events were rare, with 19 events total identified across all groups.PVI + PWI does not appear to be as effective as PVI or PVI + linear ablation in reducing the recurrence of arrhythmia within 6 months of the index procedure in patients with persistent AF. A prospective, randomized controlled trial comparing these ablation techniques is needed to clarify the role of extensive substrate modification for treatment of persistent AF.PWI is increasingly used as an adjunctive lesion set to compliment PVI in patients with persistent AF. We performed a retrospective study of 558 patients who underwent de novo and repeat ablation for persistent AF to compare the outcomes between PVI with and without adjunctive PWI. We found an increased incidence in recurrence of AF and other atrial arrhythmias at 6 months in the PVI + PWI cohort compared to PVI with or without additional linear ablation. A prospective, randomized controlled trial comparing these ablation techniques is needed to clarify the role of extensive substrate modification for treatment of persistent AF.

Abstract
Rheumatoid arthritis (RA), an autoimmune and chronic inflammatory disorder, is an incurable disease. We developed a peptide-based electrochemical sensor using electrochemical impedance spectroscopy that can be used to detect autoantibodies for RA diagnostics. We first validated that the developed peptide showed high sensitivity and could compliment the current gold standard method of an anti-cyclic citrullinated peptide antibody (anti-CCP) ELISA. The developed peptide can be modified on the nanogold surface of the working electrode of sensing chips through the method of a self-assembling monolayer. The sensing process was first optimized using a positive control cohort and a healthy control cohort. Subsequently, 10 clinically confirmed samples from RA patients and five healthy control samples were used to find the threshold value of the impedance between RA and healthy subjects. Furthermore, 10 clinically confirmed samples but with low values of anti-CCP autoantibodies were used to evaluate the sensitivity of the present method compared to the conventional method. The proposed method showed better sensitivity than the current conventional anti-CCP ELISA method.

Abstract
A rotation sensor is one of the key elements of inertial navigation systems and compliments most cell phone sensor sets used for various applications. Currently, inexpensive and efficient solutions are mechanoelectronic devices, which nevertheless lack long-term stability. Realization of rotation sensors based on spins of fundamental particles may become a drift-free alternative to such devices. Here, we carry out a proof-of-concept experiment, demonstrating rotation measurements on a rotating setup utilizing nuclear spins of an ensemble of nitrogen vacancy centers as a sensing element with no stationary reference. The measurement is verified by a commercially available microelectromechanical system gyroscope.

Abstract
Fine-needle aspiration (FNA) has long been considered the first and an important diagnostic tool in the evaluation of thyroid nodules. The advantages of FNA include simplicity, safety, cost-effectiveness, high diagnostic accuracy, and low complication rate. Nevertheless, limitations associated with FNA include a substantial rate of inconclusive results and indeterminate interpretations. Therefore, core needle biopsy (CNB) of the thyroid gland has been proposed as a complementary or even alternate diagnostic method to evaluate thyroid nodules. Although controversial, a growing number of researchers have reported CNB to be an effective and safe sampling method for thyroid nodules, especially for cases with inadequate or indeterminate FNA yields. Skeptics highlight local pain and bleeding risk. Supporters highlight the potential likelihood of overcoming FNA limitations by obtaining a larger amount of tissue and using architecture and cellular details to guide possible ancillary testing. This review evaluates the indications, advantages, and disadvantages of CNB as compared with FNA of the thyroid gland.

Abstract
Ecological momentary assessment is a valuable research technique meant to capture real-time data and contextualize disease. While more common in neuropsychiatric research, this methodology is exceptionally fit for tinnitus. Tinnitus has been shown to be affected by many patient-level and environment-specific factors. From an individual's baseline anxiety to the level of ambient noise in their environment, the level of bother experienced by those with tinnitus can vary widely. Only assessing tinnitus within a clinical environment can distort the true impact of the disease. Ecological data can minimize bias while generating an individualistic picture of the burden being experienced by the patient. Individual data can also compliment new research methods rooted in precision medicine, providing clearer, better-suited treatments for each patient on the tinnitus spectrum.

Abstract
Pandemics have shaped humanity over and over again, but the coronavirus outbreak of 2019-2020 is in a world at the tipping point of catastrophic climate change. Its origins and distinction derive from over-population with inequity and an industrial revolution since the 17th century which has exploited fossil fuels as a globalised energy source, a period now described as the anthropocene. Asymptotic ecosystem loss and dysfunction, for people whose being is socioecological, makes ultimate survival tenuous. Microbial forms of life jump species when habitats are destroyed, or their host misused. Our innate immunity depends on our general health and fitness- social, mental, physical, and nutritional, in step with nature and its rhythms through walking in it, enjoying sunlight and sleep. Biodiversity and the associated benefit of food variety, after being breast-fed, is the key descriptor of a healthful, sustainable, accessible, and acceptable way of eating. How this pattern might contribute to our resilience in the face of a highly transmissible and biologically evasive virus is becoming clear. It may also be possible to compliment usefully preventive vaccination and therapeutic healthcare and rehabilitation through a greater understanding of our nutritional biology.

Abstract
This theoretical paper introduces six emotion socialization typologies that can be used for designating emotion responsivity styles of parents and peers of children in middle childhood, referred to as Parent and Peer Emotion Responsivity Styles (PPERS). This typology draws on theoretical foundations of meta-emotion and emotion socialization. These typologies are compliment with and extend Gottman's emotion-based parenting styles, as they are organized generally by whether the response is more positive or more negative and whether the response is more emotionally constructive or destructive, but extend the four styles to include whether the parent or peer targets the emotion directly when responding to a child's emotions, or whether they target the emotion-related behavior. On the positive end, there is the Emotion Constructive style, which targets the child's emotions directly. The other two positive styles include Emotion Responsive and Emotion Acceptive, which target the child's emotional behaviors with higher or lower levels of activity. On the negative side, there is the Emotion Destructive style which is employed to target the emotion itself, while the Emotion Punitive and Emotion Dismissive styles target the child's emotion-related behavior with varying levels of activity. Implications for the development and study of these theoretical typologies are discussed.

Abstract
In order to better understand how the complex, densely packed, heterogeneous milieu of a cell influences enzyme kinetics, we exposed opposing reactions catalyzed by yeast alcohol dehydrogenase (YADH) to both synthetic and protein crowders ranging from 10 to 550 kDa. The results reveal that the effects from macromolecular crowding depend on the direction of the reaction. The presence of the synthetic polymers, Ficoll and dextran, decrease Vmax and Km for ethanol oxidation. In contrast, these crowders have little effect or even increase these kinetic parameters for acetaldehyde reduction. This increase in Vmax is likely due to excluded volume effects, which are partially counteracted by viscosity hindering release of the NAD+ product. Macromolecular crowding is further complicated by the presence of a depletion layer in solutions of dextran larger than YADH, which diminishes the hindrance from viscosity. The disparate effects from 25 g/L dextran or glucose compared to 25 g/L Ficoll or sucrose reveals that soft interactions must also be considered. Data from binary mixtures of glucose, dextran, and Ficoll support this "tuning" of opposing factors. While macromolecular crowding was originally proposed to influence proteins mainly through excluded volume effects, this work compliments the growing body of evidence revealing that other factors, such as preferential hydration, chemical interactions, and the presence of a depletion layer also contribute to the overall effect of crowding.

Abstract
Background: Currently, PCR assay is a golden standard for diagnosis of Covid-19. However, it needs nasopharyngeal swabs, expensive instruments and expertise. It even causes PCR errors.
Methods: We validated the antibody assay (Roche) in 36 followed patients and 1879 controls (medical staffs).
Results: Of 1879 medical staffs, only two (0.11%) were positive by Cut off Index (COI; 1.0) (mean ± SD, 0.094 ± 0.047). Thirty six patients were composed of three groups; Group A,4 from Diamond Princess cruise ship, Group B, 2 infected in Africa, and Group C, 30 infected in Japan. PCR assays were conducted at outside laboratories before and repeated in house after hospitalized. Of 36 at admission, positive antibody was seen in 4/4 from the ship, 0/2 from Africa, and 5/30 from Japan. Two from Africa showed the increase of COI and became positive on days 8 and 13. Thirty Japanese was divided in two groups, e.g., 23 showed dynamic increase of COI up to 84.4 within 3 days while active virus replication present (Group C). In remaining 7 (7/30, 23%) (Group C'), no rise of antibody nor positive in house PCR assays, indicative of false positive results of PCR at the beginning.
Conclusion: This antibody testing has a wide dynamic ranges of COI and, thus, could be utilized in the early infection phase. This may also compliment and even help to avoid possible PCR errors. Therefore, this can serve as a powerful diagnostic tool, needed in the frontline of the clinic and hospitals.

Abstract
This study compliments previous work where peroxidase was successfully used to crosslink corn fiber gum (CFG) with bovine serum albumin and improve CFG's emulsifying properties. Herein, an alternative type of enzyme, transglutaminase, was used to prepare conjugates of CFG and sodium caseinate. Additionally, the CFG was partially hydrolyzed by sulfuric acid and its crosslinking pattern with caseinate was evaluated. The interfacial crosslinking degree between caseinate and CFG increased after hydrolysis according to high performance size exclusion chromatography. The equilibrium interfacial tension of CFG hydrolysate-caseinate conjugate was lower than that of CFG-caseinate conjugate as the rearrangement rate of the CFG hydrolysate-caseinate conjugate was higher. The dilatational modulus of CFG hydrolysate decreased from that of CFG.

Abstract
Fludeoxyglucose F18 (FDG) is a positron-emitting radiotracer used in conjunction with positron emission tomography (PET) for diagnosis and monitoring of various conditions. Standard imaging modalities such as X-ray, CT, and MRI allows the visualization of healthy and diseased tissue with great details. However, some diseases do not have any structural anatomic abnormalities, or they do not manifest until the late stage. Therefore, functional imaging techniques like PET scan can compliment structural modalities on overcoming some of the deficiencies. PET scan uses radiotracers that are injected into the patient before the scan to visualize the blood flow, metabolic, and biochemical activities in diseased and healthy tissues. FDG is a glucose analog, and it tends to accumulate in the tissue with high glucose demand like tumors and inflammatory cells.

Abstract
Students learn science by actually performing science activities. The 12 laboratories described in this article assist students in applying the fundamental techniques germane to the field of forensic science to "solve" contrived cases and present "evidence" in a mock trial. Moreover, students are also confronted with some of the legal and ethical issues concerning the validity, reliability, and application of some forensic techniques. The pedagogical design of the laboratory course provides a rich, challenging, and interdisciplinary academic experience intended to augment and compliment the didactic forensic lecture portion of the course. This laboratory course was designed to engender, embody, and articulate one of the University's directive goals to support interdisciplinary teaching, research, and programming. Because we developed the laboratories on minimal funds, we demonstrated that it could be cost-effective. And thus, we recommend a laboratory science course be included as part of the curriculum of all forensic nursing students and practitioners.

Abstract
Non-technical skills are the cognitive and interpersonal behaviours that compliment clinical competence in surgery. Effective use of non-technical skills is essential for scrub practice, because they facilitate anticipation of the surgeon's requirements and promote appropriate communication behaviours. This literature review analyses the factors that may influence a scrub practitioner's use of non-technical skills during surgery. Recommendations are made that are intended to improve their use by reducing behavioural variations during surgery.

Abstract
Redesigning acute mental health services: an audit into the quality of inpatient care before and after service redesign in Grampian As part of the redesign of adult mental health services in Grampian and in line with the Scottish Framework for Mental Health (1997), the decision was made to close one of the five acute mental health admission wards within Royal Cornhill Hospital. Inpatient services were to be provided within the remaining four admission wards by increasing their bed compliment from 25 to 28 and by increasing the staffing compliment of the community mental health teams serving Aberdeen city and Aberdeenshire. The adult mental health directorate commissioned an audit to measure certain key items in the 6 months leading up to the redesign and in the 6 months post redesign. This audit focused on the number of admissions, the bed occupancy, the number of incidents, the number of days the ward doors were locked, observation levels, sickness levels and the number of bank hours used. These factors were felt to be important indicators in the monitoring of the quality of patient care as any increase in the instance of these factors could be seen as detrimental to patient care. Therefore, a comparison of these factors, pre- and post-ward closure, was seen as a useful method of assessing the effect of the ward closure and the subsequent loss of seven acute inpatient beds. As the results of the audit showed that the rate of these factors had not increased, it was assumed the quality of care in the inpatient service was as at least as good following the redesign as it was before it. Two issues arose from the audit that merit further discussion, that is, the differences in the numbers of observations and in the numbers of times the ward doors were locked. Two G grade community psychiatric nurses were employed on a 0.5 session per week basis to collect and collate the data.
