Abstract
Despite extensive preclinical testing, cancer therapeutics can result in unanticipated toxicity to non-tumor tissue in patients. These toxicities may pass undetected in preclinical experiments due to modeling limitations involving poor biomimicry of 2-dimensional in vitro cell cultures and due to lack of interspecies translatability in in vivo studies. Instead, primary cells can be grown into miniature 3-dimensional structures that recapitulate morphological and functional aspects of native tissue, termed "organoids." Here, human bronchioalveolar organoids grown from primary alveolar epithelial cells were employed to model lung epithelium and investigate off-target toxicities associated with antibody-drug conjugates (ADCs). ADCs with three different linker-payload combinations (mafodotin, vedotin, and deruxtecan) were tested in bronchioalveolar organoids generated from human, rat, and nonhuman primate lung cells. Organoids demonstrated antibody uptake and changes in viability in response to ADC exposure that model in vivo drug sensitivity. RNA sequencing identified inflammatory activation in bronchioalveolar cells in response to deruxtecan. Future studies will explore specific cell populations involved in interstitial lung disease and incorporate immune cells to the culture.

Abstract
Extensive efforts have been undertaken to combine superconductivity and the quantum Hall effect so that Cooper-pair transport between superconducting electrodes in Josephson junctions is mediated by one-dimensional edge states1-6. This interest has been motivated by prospects of finding new physics, including topologically protected quasiparticles7-9, but also extends into metrology and device applications10-13. So far it has proven challenging to achieve detectable supercurrents through quantum Hall conductors2,3,6. Here we show that domain walls in minimally twisted bilayer graphene14-18 support exceptionally robust proximity superconductivity in the quantum Hall regime, allowing Josephson junctions to operate in fields close to the upper critical field of superconducting electrodes. The critical current is found to be non-oscillatory and practically unchanging over the entire range of quantizing fields, with its value being limited by the quantum conductance of ballistic, strictly one-dimensional, electronic channels residing within the domain walls. The system described is unique in its ability to support Andreev bound states at quantizing fields and offers many interesting directions for further exploration.

Abstract
BACKGROUND Families face a range of barriers in supporting their children's active play in nature including family circumstances, environmental constraints, and behavioral factors. Evidence-based strategies to address these barriers are needed. We aimed to develop and pilot test a primary care-based family-centered behavioral intervention to promote active outdoor play in 4-10 year-old children. METHODS Project Nature, a provider-delivered intervention that provides informational resources and an age-appropriate toy for nature play, was initially developed for children ages 0-3. With stakeholder input, we adapted existing materials for 4-10 year-olds and conducted usability testing at an urban clinic serving families from diverse backgrounds. Subsequently, we conducted a mix-methods pilot study to evaluate intervention feasibility and acceptability. Parents of 4-10 year-olds completed pre- and post-surveys (n = 22), and a purposive subset (n = 10) completed qualitative interviews. Post-intervention, pediatric providers (n = 4) were interviewed about their implementation experiences. RESULTS The majority (82%) of parents liked the information provided and the remaining (18%) were neutral. Qualitatively, parents reported that: the toy provided a tangible element to help children and parents be active, they did not use the website, and they wished the intervention emphasized strategies for physical activity during cold and wet seasons. Providers felt the materials facilitated discussion about behavior change with families. There were no statistically significant changes in PA and outdoor time pre- and post-intervention. CONCLUSIONS Project Nature was welcomed by providers and families and may be a practical intervention to promote outdoor active play during well-child visits. Providing an age-appropriate nature toy seemed to be a critical component of the intervention, and may be worth the additional cost, time and storage space required by clinics. Building from these results, Project Nature should be revised to better support active outdoor play during suboptimal weather and evaluated to test its efficacy in a fully-powered trial.

Abstract
Chronic wasting disease (CWD) is a highly infectious, fatal prion disease that affects cervid species. One promising method for CWD surveillance is the use of detection dog-handler teams wherein dogs are trained on the volatile organic compound signature of CWD fecal matter. However, using fecal matter from CWD-positive deer poses a biohazard risk; CWD prions can bind to soil particles and remain infectious in contaminated areas for extended periods of time, and it is very difficult to decontaminate the affected areas. One solution is to use noninfectious training aids that can replicate the odor of fecal matter from CWD-positive and CWD-negative deer and are safe to use in the environment. Trained CWD detection dogs' sensitivity and specificity for different training aid materials (cotton, GetXent tubes, and polydimethylsiloxane, or PDMS) incubated with fecal matter from CWD-positive and CWD-negative deer at two different temperatures (21 °C and 37 °C) for three different lengths of time (6 h, 24 h, and 48 h) were evaluated. Cotton incubated at 21 °C for 24 h was identified as the best aid for CWD based on the dogs' performance and practical needs for training aid creation. Implications for CWD detection training and for training aid selection in general are discussed.

Abstract
PURPOSE/OBJECTIVE(S) High precision radiotherapy for small animal radio-neuromodulation requires conformal treatment to very small targets down to 2.5 mm. A focused kV technique based on novel usage of polycapillary x-ray lenses can focus x-ray beams to <0.2 mm in diameter, which is ideal for such uses. Such application also requires high resolution CT images for treatment planning and setup, which was hard to achieve using conventional x-ray tube. In this work, we demonstrate the feasibility of using a virtual focal spot generated with an x-ray lens to perform high-resolution CBCT acquisition. MATERIALS/METHODS The experiment with x-ray lens was set up on an x-ray tabletop system to generate a virtual focal spot. A pinhole image was acquired for the virtual focal spot and compared with the one acquired with the conventional focal spot without the lens. The planar imaging resolution with and without the lens were evaluated using a line pair resolution phantom. The spatial resolution of the two settings were estimated by reconstructing a 0.15-mm wire phantom and comparing its full width half maximum (FWHM). A CBCT scan of a rodent head was also acquired to further demonstrate the improved resolution using the x-ray lens. RESULTS Compared to conventional imaging acquisition with a measured x-ray focal spot of 0.395 mm FWHM, the virtual focal spot size was measured at 0.175 mm. The reduction in focal spot size with lens leads to an almost doubled planar imaging resolution and a 26% enhancement in 3D spatial resolution. A realistic CBCT acquisition of a rodent head mimicked the imaging acquisition step for radio-neuromodulation and further showed the improved visualization for fine structures. CONCLUSION This work demonstrated that the focused kV x-ray technique was capable of generating small focal spot size of <0.2 mm. The proposed method provides an adaptive imaging platform to acquire x-ray and CBCT images for treatment planning and setup with improved spatial resolution compared to conventional CBCT image acquisition.

Abstract
The spread of SARS-CoV-2, which causes the disease COVID-19, is difficult to control as some positive individuals, capable of transmitting the disease, can be asymptomatic. Thus, it remains critical to generate noninvasive, inexpensive COVID-19 screening systems. Two such methods include detection canines and analytical instrumentation, both of which detect volatile organic compounds associated with SARS-CoV-2. In this study, the performance of trained detection dogs is compared to a noninvasive headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) approach to identifying COVID-19 positive individuals. Five dogs were trained to detect the odor signature associated with COVID-19. They varied in performance, with the two highest-performing dogs averaging 88% sensitivity and 95% specificity over five double-blind tests. The three lowest-performing dogs averaged 46% sensitivity and 87% specificity. The optimized linear discriminant analysis (LDA) model, developed using HS-SPME-GC-MS, displayed a 100% true positive rate and a 100% true negative rate using leave-one-out cross-validation. However, the non-optimized LDA model displayed difficulty in categorizing animal hair-contaminated samples, while animal hair did not impact the dogs' performance. In conclusion, the HS-SPME-GC-MS approach for noninvasive COVID-19 detection more accurately discriminated between COVID-19 positive and COVID-19 negative samples; however, dogs performed better than the computational model when non-ideal samples were presented.

Abstract
Interval programs have been developed for multiple sports, allowing athletes to return to sport-specific activity in a graded fashion, minimizing the risk of reinjury. However, there currently exists a gap in the literature surrounding the use of interval programs for the rehabilitation of punting and place-kicking athletes. We aim to perform a systematic review of the literature examining the use of interval kicking programs to aid punting and place-kicking athletes following a lower-extremity injury. Following PRISMA guidelines, a review was performed using PubMed and MEDLINE databases to evaluate the literature surrounding interval kicking programs for punting and place-kicking athletes. Search terms were combined using Boolean operators of "AND" and "OR". Articles included in this review met these criteria: 1) included patients with lower-extremity pain/injury, 2) reported a return to sport progressive program, and 3) analyzed the measure's ability to predict a successful return to sport. The initial search returned 115 articles. Seventy-nine of these articles were excluded after initial screening, leaving 36 full-text articles for final review. Of these final articles, there were no studies outlining the use of interval kicking programs by punting or place-kicking athletes. Of the articles reviewed, the most relevant was an interval kicking program developed by Arundale et al. specifically for the soccer athlete. Punting and place-kicking use biomechanically distinct patterns of movement, warranting a specific interval program. This review identified a gap in knowledge surrounding the use of interval programs in the rehabilitation of punting and place-kicking athletes. This review will now describe what is currently known regarding biomechanics of punting and place kicking, the injuries experienced by these athletes, and the benefit an individualized interval program could provide. There currently exists a gap in the literature surrounding the use of interval programs for the rehabilitation of punting and place-kicking athletes. The biomechanics and application of these skills are distinct, and an interval program designed specifically for these athletes is warranted. Future research should be dedicated to the development, implementation, and analysis of an interval kicking program designed for these athletes.

Abstract
Abstract
Introduction
This study aimed to assess the impact of the COVID-19 pandemic on the sleep of adult patients of a multidisciplinary sleep clinic.
Methods
Patients were invited to complete online surveys: Survey 1 in October 2020 (increased COVID-19 restrictions) followed by Survey 2 in February 2021 (after easing of restrictions for a COVIDSafe summer).
Results
Of the 746 patients invited to participate, 73 completed and 8 partially returned Survey 1 (mean age 50.1 years, range 21–83 years, 58% female). Subsequently, 46 completed and 5 partially answered Survey 2. In Survey 1, 22/74 (29.7%) reported reduced sleep quantity and 31/75 (41.3%) indicated worse sleep quality compared with prior to the pandemic. In Survey 2, 33/46 (71.7%) described unchanged sleep quantity whilst 5/46 (10.9%) reported increased sleep quantity since easing COVID-19 restrictions. 36/46 (78.3%) indicated unchanged sleep quality whereas 5/46 (10.9%) described improved sleep quality since easing restrictions. However, 9/46 (19.6%) reported that their sleep remained worse compared with pre-pandemic. For patients who completed both surveys, there was no significant change in Insomnia Severity Index scores (Survey 1 mean 13.6, Survey 2 mean 12.9, mean difference -0.67 [95%CI -2.02, 0.68], p=0.32) or PROMIS Sleep-Related Impairment 8a T-scores (Survey 1 mean 59.0, Survey 2 mean 59.5, mean difference 0.44 [95%CI -1.55, 2.42], p=0.66).
Discussion
The COVID-19 pandemic has negatively affected the sleep of 44% of patients. Following easing of restrictions, symptoms of insomnia and sleep-related impairment did not change significantly, and 19.6% reported that their sleep was not back to their pre-pandemic baseline.

Abstract
INTRODUCTION Information on the long-term treatment satisfaction with secukinumab for patients with plaque psoriasis in real-world settings is limited. The objective of this study was to describe real-world treatment satisfaction in patients with plaque psoriasis who initiated secukinumab using data from an electronic medical records-based dermatology database. METHODS Patients aged ≥ 18 years with plaque psoriasis in Modernizing Medicine Data Services' affiliate's database who received secukinumab 3/1/2018-1/21/2020 were included. Satisfaction with the treatment's effectiveness in clearing the skin of psoriasis was evaluated using a 5-point Likert scale during the 12-month baseline period and at 6-, 12-, 18-, and 24-month postindex visits for the overall population and at 6-, 12-, and 18-month postindex visits for subgroups stratified by prior biologic and systemic therapy use. Additionally, satisfaction levels were assessed among patients who were unsatisfied with treatment at baseline. RESULTS Overall, 82.3% agreed that secukinumab was effective in clearing their skin at 6 months, which was maintained through 12 (81.7%), 18 (83.3%), and 24 months (81.4%). Similar results were observed in biologic-experienced/naive and systemic-experienced/naive patients. Overall mean (SD) treatment satisfaction improved from 2.49 (1.36) at baseline to 1.77 (1.06) at 6 months, with similar improvements in satisfaction scores reported at each follow-up period up through 24 months. Of the patients who were not satisfied at baseline, 77.9% reported being satisfied with their treatment at 6 months, which continued through 12 (74.4%), 18 (82.8%), and 24 months (71.4%). Patients receiving secukinumab experienced meaningful changes in percent affected body surface area and Physician Global Assessment scores that were sustained through 24 months, regardless of prior treatment experience. CONCLUSIONS These real-world findings highlight the high level of sustained satisfaction with secukinumab treatment for improving and maintaining skin clearance in patients with moderate-to-severe disease, regardless of prior treatment experience.

Abstract
On-target, off-tissue toxicity limits the systemic use of drugs that would otherwise reduce symptoms or reverse the damage of arthritic diseases, leaving millions of patients in pain and with limited physical mobility. We identified cystine-dense peptides (CDPs) that rapidly accumulate in cartilage of the knees, ankles, hips, shoulders, and intervertebral discs after systemic administration. These CDPs could be used to concentrate arthritis drugs in joints. A cartilage-accumulating peptide, CDP-11R, reached peak concentration in cartilage within 30 min after administration and remained detectable for more than 4 days. Structural analysis of the peptides by crystallography revealed that the distribution of positive charge may be a distinguishing feature of joint-accumulating CDPs. In addition, quantitative whole-body autoradiography showed that the disulfide-bonded tertiary structure is critical for cartilage accumulation and retention. CDP-11R distributed to joints while carrying a fluorophore imaging agent or one of two different steroid payloads, dexamethasone (dex) and triamcinolone acetonide (TAA). Of the two payloads, the dex conjugate did not advance because the free drug released into circulation was sufficient to cause on-target toxicity. In contrast, the CDP-11R-TAA conjugate alleviated joint inflammation in the rat collagen-induced model of rheumatoid arthritis while avoiding toxicities that occurred with nontargeted steroid treatment at the same molar dose. This conjugate shows promise for clinical development and establishes proof of concept for multijoint targeting of disease-modifying therapeutic payloads.

Abstract
Objectives: To evaluate if nurses can reliably perform ultrasound-guided peripheral intravenous catheter placement in children with a high success rate after an initial training period. A secondary aim was to analyze complication rates of ultrasound-guided peripheral intravenous catheters. Methods: A database recorded all ultrasound-guided peripheral intravenous catheter encounters in the emergency department from November 2013 to April 2019 including the emergency department nurse attempting placement, number of attempts, and whether it was successful. Patient electronic medical records were reviewed for the time of and reason for intravenous removal. The probabilities of first-attempt successful intravenous placement and complication at successive encounters after an initial training period were calculated. These probabilities were plotted versus encounter number to graph best-fit logarithmic regressions. Results: A total of 83 nurses completed a standardized training program in ultrasound-guided peripheral intravenous catheter placement including 10 supervised ultrasound-guided peripheral intravenous catheter placements. In total, 87% (3513/4053) of the ultrasound-guided peripheral intravenous catheter placed after the training program were successful on the first attempt. The probability of successfully placing an ultrasound-guided peripheral intravenous catheter increased as nurses had more experience placing ultrasound-guided peripheral intravenous catheters (R2 = 0.18) and was 83% at 10 encounters. Twenty-five percent (904/3646) of ultrasound-guided peripheral intravenous catheters had complications, and there was no statistically significant relationship between the number of encounters per nurse and complication rates (R2 < 0.001). Conclusion: Nurses can reliably place ultrasound-guided peripheral intravenous catheters at a high success rate after an initial training period. First-attempt success rates were high and increased from 67% to 83% for the first 10 unsupervised encounters after training and remained high. The complication rate was low and did not change as nurses gained more experience.

Abstract
The impenetrability of the blood-brain barrier (BBB) to most conventional drugs impedes the treatment of central nervous system (CNS) disorders. Interventions for diseases like brain cancer, neurodegeneration, or age-associated inflammatory processes require varied approaches to CNS drug delivery. Cystine-dense peptides (CDPs) have drawn recent interest as drugs or drug-delivery vehicles. Found throughout the phylogenetic tree, often in drug-like roles, their size, stability, and protein interaction capabilities make CDPs an attractive mid-size biologic scaffold to complement conventional antibody-based drugs. Here, we describe the identification, maturation, characterization, and utilization of a CDP that binds to the transferrin receptor (TfR), a native receptor and BBB transporter for the iron chaperone transferrin. We developed variants with varying binding affinities (KD as low as 216 pM), co-crystallized it with the receptor, and confirmed murine cross-reactivity. It accumulates in the mouse CNS at ~25% of blood levels (CNS blood content is only ~1%-6%) and delivers neurotensin, an otherwise non-BBB-penetrant neuropeptide, at levels capable of modulating CREB signaling in the mouse brain. Our work highlights the utility of CDPs as a diverse, easy-to-screen scaffold family worthy of inclusion in modern drug discovery strategies, demonstrated by the discovery of a candidate CNS drug delivery vehicle ready for further optimization and preclinical development.

Abstract
OBJECTIVES Although IVIG infusions are usually well tolerated, reactions can include hypotension, chills, and, rarely, anaphylactic reactions. Risk of adverse reactions correlates with dose and rate of IVIG infusion. An echocardiogram is the preferred imaging modality to detect coronary artery changes in acute Kawasaki disease (KD), but the quality of the study can be compromised if a child moves much during the imaging procedure. Thus, sedation is often required for children younger than 3 years of age. There is concern regarding coadministration of IVIG and sedatives. Therefore, the purpose of this analysis is to determine when the majority of IVIG infusion reactions occur to help find the optimal time to safely perform a sedated echocardiogram in patients with KD. METHODS This is a retrospective, single-center analysis of patients with KD administered IVIG at Rady Children's Hospital San Diego from November 1, 2013, to October 31, 2016. RESULTS Of the 260 subjects in this study, 34 (13%) had an IVIG infusion reaction consisting of either chills or hypotension. There were no anaphylactic reactions. All infusion reactions occurred within 4 hours of starting IVIG. No hypotension reactions occurred after 4 hours. All subjects were able to complete their IVIG infusion without any further complications. CONCLUSIONS Given that the maximum IVIG infusion rate is reached at 1.5 hours per our hospital's policy and that the overwhelming majority of infusion reactions occurred within the first 4 hours, we found it is safe to coadminister IVIG with sedation 4 hours after initiation of IVIG infusion.

Abstract
FGF21, an important metabolic regulator, has recently been suggested as a biomarker for heart failure (HF). FGF21 is involved in the integrated mitochondrial stress response, and has been shown to be upregulated with mitochondrial DNA damage, which occurs more frequently in dilated cardiomyopathy. In this study, we investigated whether FGF21 can be used as a biomarker for metabolic stress in HF. We collected blood and cardiac tissue samples from ischemic and non-ischemic HF patients who have undergone VAD transplantation. We also collected blood and tissue from mice with HF due to 1) combination of transverse aortic constriction and coronary artery ligation (TAC+Lig) or 2) cardiac-specific knockout of the mitochondrial transcription factor A (Tfam). Serum FGF21 levels were measured using Enzyme-linked immunosorbent assay (ELISA). Messenger RNA was extracted from the tissue and FGF21 gene expression was measured using real-time quantitative PCR (qPCR). Immunohistochemical staining was performed on tissue sections (either paraffin embedded or frozen) to observe FGF21 levels. Serum FGF21 was elevated in human HF patients compared to healthy controls, as well as in both mouse models of HF. In human patients, cardiac FGF21 gene expression was upregulated 2.2-fold compared to donors. In the TAC+Lig mouse model we observed a 3.37-fold increase, while the Tfam knockout model which has severe mitochondrial damage exhibited a 218-fold increase in cardiac FGF21 gene expression. Further qPCR assays revealed changes in FGF21 gene expression in the liver and white fat of TFAM-KO, indicating metabolic stress on other organs resulting from HF. In conclusion, serum FGF21 is elevated in multiple models of HF, and appears to have both cardiac and extra cardiac sources. Future work will investigate 1) whether there is a correlation between FGF21 levels and mitochondrial damage, and 2) the signaling pathway resulting in metabolic stress to other organs in HF.

Abstract
Despite significant progress, our understanding of how specific oncogenes transform cells is still limited and likely underestimates the complexity of downstream signalling events. To address this gap, we use mass spectrometry-based chemical proteomics to characterize the global impact of an oncogene on the expressed kinome, and then functionally annotate the regulated kinases. As an example, we identify 63 protein kinases exhibiting altered expression and/or phosphorylation in Src-transformed mammary epithelial cells. An integrated siRNA screen identifies nine kinases, including SGK1, as being essential for Src-induced transformation. Accordingly, we find that Src positively regulates SGK1 expression in triple negative breast cancer cells, which exhibit a prominent signalling network governed by Src family kinases. Furthermore, combined inhibition of Src and SGK1 reduces colony formation and xenograft growth more effectively than either treatment alone. Therefore, this approach not only provides mechanistic insights into oncogenic transformation but also aids the design of improved therapeutic strategies. The systemic understanding of oncogenic kinase signalling is still limited. Here, the authors combine chemical proteomics with functional screens to assess the impact of oncogenic Src on the expressed kinome and identify SGK1 as a critical mediator of Src-induced cell transformation.

Abstract
The innate immune response tends to become hyperactive and proinflammatory in older organisms. We investigated connections between activity of the immune-related genes and aging using the Drosophila model. A hallmark of Drosophila immunity is the production of antimicrobial peptides (AMP), whose expression is triggered via activation of the Toll and Imd immune pathways and regulated by NF-ĸB-like transcription factors, Dif/Dorsal and Relish. It was previously shown that overexpression of the upstream component of the immune pathways shortens lifespan via activation of the Relish-dependent immune response. Here we show that direct overexpression of the Relish target AMP genes broadly at high levels or in the fat body induced apoptosis, elicited depolarization of the mitochondria and significantly shortened lifespan. Underexpression of Relish in the fat body beginning in the second half of lifespan prevented overactivation of AMPs and extended longevity. Unlike infection-induced responses, the age-related increase in AMPs does not require the upstream recognition/transduction module of the Imd pathway. It does however require downstream elements, including Relish and Ird5, a component of the downstream IKK complex. Together, these results established causal links between high-level production of antimicrobial peptides and longevity.

Abstract
Essentials Clinical prediction rules (CPRs) can stratify patients with pulmonary embolism (PE) and cancer. A meta-analysis was done to assess prognostic accuracy in CPRs for mortality in these patients. Eight studies evaluating ten CPRs were included in this study. CPRs should continue to be used with other patient factors for mortality risk stratification. SUMMARY Background Cancer treatment is commonly complicated by pulmonary embolism (PE), which remains a leading cause of morbidity and mortality in these patients. Some guidelines recommend the use of clinical prediction rules (CPRs) to help clinicians identify patients at low risk of mortality and therefore guide care. Objective To determine and compare the accuracy of available CPRs for identifying cancer patients with PE at low risk of mortality. Methods A literature search of Medline and Scopus (January 2000 to August 2017) was performed. Studies deriving/validating ≥ 1 CPR for early post-PE all-cause mortality were included. A bivariate, random-effects model was used to pool sensitivity and specificity estimates for each CPR. Traditional random-effects meta-analysis was performed to estimate the weighted proportion of patients deemed at low risk of early mortality, mortality in low risk patients and odds ratios for death compared with higher-risk patients. Results Eight studies evaluating 10 CPRs were included. The highest sensitivities were observed with Hestia (98.1%, 95% confidence interval [CI] = 75.6-99.9%) and the EPIPHANY index (97.4%, 95% CI = 93.2-99.0%); sensitivities of remaining rules ranged from 59.9 to 96.6%. Of the six CPRs with sensitivities ≥ 95%, none had specificities > 33%. Random-effects meta-analysis suggested that 6.6-51.6% of cancer patients with PE were at low risk of mortality, 0-14.3% of low-risk patients died and low-risk patients had a 43-94% lower odds of death compared with those at higher risk. Conclusions Because of the limited total body of evidence regarding CPRs, their results, in conjunction with other pertinent patient-specific clinical factors, should continue to be used in identifying appropriate management for PE in patients with cancer.

Abstract
INTRODUCTION The adoption of robot-assisted laparoscopic (RAL) procedures in the field of urology has occurred rapidly, but is, to date, without pediatric-specific instrumentation. Surgical fog is a significant barrier to safe and efficient laparoscopy. This appears to be a significant challenge when adapting three-dimensional 8.5-mm scopes to use in pediatric RAL surgery. The objective of the present study was to compare matched controls from a prospectively collected database to procedures that were performed utilizing special equipment and a protocol to minimize surgical fog in pediatric RAL procedures. METHODS A prospectively collected database of all patients who underwent RAL pediatric urology procedures was used to compare: procedure, age, sex, American Society of Anesthesiologists score, weight, console time, number of times the camera was removed to clean the lens during a procedure, length of hospital stay, and morphine equivalents required in the postoperative period. A uniquely developed protocol was used, it consisted of humidified (95% relative humidity) and warmed CO2 gas (95 °F) insufflation via Insuflow® on a working trocar, with active smoke evacuation via PneuVIEW®XE on the opposite working trocar with a gas pass through of 3.5-5 l/min. The outcomes were compared with matched controls (Summary Fig). RESULTS The novel gas protocol was utilized in 13 procedures (five pyeloplasties, two revision pyeloplasties, three ureteroureterostomies (UU), three nephrectomies) and compared with 13 procedures (six pyeloplasties, one revision pyeloplasty, three UU, three nephrectomies) prior to the protocol development. There was no statistical difference in age (P = 0.78), sex (P = 0.11), ASA score (P = 1.00) or weight (P = 0.69). There were no open conversions, ≥Grade 2 Clavien complications, or readmissions within 30 days in either group. CONCLUSIONS This novel gas protocol yielded a statistically significant reduction in procedure time, by decreasing the number of times the camera was required to be pulled during the case by more than five occurrences, and saved approximately 35 min on average per case.

Abstract
OBJECTIVES This study evaluated the effectiveness of the Center for Executive Medicine (CEM) concierge primary care practice on preventive colorectal cancer (CRC) screening rates relative to local and national comparator data. METHODS We performed an electronic medical record search encompassing our entire patient population who are between the ages of 50 and 75 years to determine the rate of CRC screening. We compared this rate with the average rate of Medicare Advantage plans reported by our Independent Physician Association (IPA) in 2015 and national health plans reported by the National Committee for Quality Assurance in 2014. RESULTS The CEM had a CRC screening rate of 90.2%, which was significantly higher than local IPA Medicare Advantage plans (63.3%) and National Committee for Quality Assurance national plans (57.7%-66.5%). CEM members were significantly more likely than were IPA members to undergo screening (odds ratio 1.425, 95% confidence interval 1.348-1.507, P < 0.0001). CONCLUSIONS These results suggest that the CEM practice strategy and processes increase CRC screening rates.

Abstract
WHAT IS KNOWN AND OBJECTIVE Proactive synchronization of medication refills through an appointment-based model (ABM) is a community pharmacy-based intervention targeting adherence to medications. We aimed to systematically review evidence on the impact of the ABM on medication taking behaviour, health resource utilization, clinical outcomes and the preferences of patients and providers. METHODS We conducted a systematic literature search of MEDLINE and Scopus from database inception through 6 February 2017. Studies were included if they were original investigations evaluating the impact of the ABM on at least one outcome of interest and published in the peer-reviewed literature as a full-text manuscript in the English language. Outcomes included medication taking behaviour, clinical and economic outcomes, health resource utilization, and patient or provider satisfaction. Data were synthesized qualitatively. RESULTS Five studies, mostly observational in design and with low risk of bias, were included. Objective measures of medication taking behaviour were consistently improved in patients enrolled in an ABM vs control, indicating an association between appointment-based medication synchronization with improved adherence and decreased likelihood of non-persistence. A single decision analysis indicates a cost savings over 1 year associated with the appointment-based medication synchronization programme modelled, for hypertension, diabetes and hyperlipidaemia. Limited data regarding health resource utilization and clinical outcomes and patient or provider satisfaction exist and are currently inconclusive. WHAT IS NEW AND CONCLUSION The ABM provides a unique, patient-centred service to improve medication adherence amongst patients taking chronic medications while demonstrating a positive financial return on investment. Future research is needed to determine the impact of the ABM on final health outcomes.

Abstract
Sulfur-lone pair interactions are important conformational control elements in sulfur-containing heterocycles that abound in pharmaceuticals, natural products, agrochemicals, polymers and other important classes of organic molecules. Nonetheless, the role of intramolecular sulfur-lone pair interactions in the binding of small molecules to receptors is often overlooked. Here we analyze the magnitudes and origins of these interactions for a variety of biologically relevant small molecules using quantum chemical and automated docking calculations. In most cases examined in this study, the lowest energy conformation of the small molecule displays a sulfur-lone pair close contact. However, docking studies, both published and new, often predict that conformations without sulfur-lone pair contacts have the best binding affinity for their respective receptors. This is a serious problem. Since many of these predicted bound conformations are not actually energetically accessible, pursuing design (e.g., drug design) around these binding modes necessarily will lead, serendipity aside, to dead end designs. Our results constitute a caution that one best not neglect these interactions when predicting the binding affinities of potential ligands (drugs or not) for hosts (enzymes, receptors, DNA, RNA, synthetic hosts). Moreover, a better understanding and awareness of sulfur-lone pair interactions should facilitate the rational modulation of host-guest interactions involving sulfur-containing molecules.

Abstract
Toxoplasma gondii, a common brain-tropic parasite, is capable of infecting most nucleated cells, including astrocytes and neurons, in vitro. Yet, in vivo, Toxoplasma is primarily found in neurons. In vitro data showing that interferon-γ-stimulated astrocytes, but not neurons, clear intracellular parasites suggest that neurons alone are persistently infected in vivo because they lack the ability to clear intracellular parasites. Here we test this theory by using a novel Toxoplasma-mouse model capable of marking and tracking host cells that directly interact with parasites, even if the interaction is transient. Remarkably, we find that Toxoplasma shows a strong predilection for interacting with neurons throughout CNS infection. This predilection remains in the setting of IFN-γ depletion; infection with parasites resistant to the major mechanism by which murine astrocytes clear parasites; or when directly injecting parasites into the brain. These findings, in combination with prior work, strongly suggest that neurons are not incidentally infected, but rather they are Toxoplasma's primary in vivo target.

Abstract
OBJECTIVE We hypothesized that the incidence of endothermal heat-induced thrombosis (EHIT) depends on the laser wavelength used in endovenous laser ablation (EVLA) of the saphenous veins. METHODS We identified patients undergoing EVLA in our office from 2005 to 2014 with an 810-nm (hemoglobin-specific) or 1470-nm (water-specific) laser. We reviewed the records for age, sex, body mass index, Clinical, Etiologic, Anatomic, and Pathophysiologic (CEAP) class, vein diameter, vein(s) treated, adjunctive phlebectomy, energy delivered, laser pullback times, and EHIT (closure level ≥3) development. The Fisher exact test and Pearson χ(2) test were used to evaluate the association between EHIT and the categoric variables. Logistic regression was used to evaluate the relationship between EHIT and the continuous variables. RESULTS There were 1439 veins ablated in 1109 patients (769 female, 340 male). The great saphenous vein (GSV) was treated in 1332, the small saphenous vein (SSV) in 78, and both in 29 (22 procedures on accessory veins were excluded). The CEAP C class for these patients was 1 in 0, 2 in 616, 3 in 522, 4 in 150, 5 in 51, and 6 in 98, and was not recorded in 2. EHIT occurred in 76 cases (5.28%), in 73 after GSV ablation and in three after SSV ablation. The 810-nm laser was used in 1144 procedures, and EHIT developed in 69 patients (6.0%). The 1470-nm laser was used in 295 procedures, with EHIT developing in seven patients (2.4%; P = .0122 by Fisher exact test). The average energy delivered to the EHIT group (3517 ± 1998.1 J) was higher than for the non-EHIT group (2825.1 ± 1491.2 J; P = .0002). The average vein diameter was larger in the EHIT group (9.3 ± 3.8 mm) than in the non-EHIT group (7.2 ± 3.3 mm; P = .0001). EHIT occurred in 59 of 837 cases (6.6%) undergoing simultaneous stab phlebectomy compared with 17 of 525 cases (3.1%) undergoing only EVLA (P = .0049). Statistical analysis confirmed the association between EHIT and CEAP class was significant (P = .0001). No differences were seen for age, body mass index, sex, combined bilateral, and multiple or simultaneous GSV and SSV ablations between the two groups. A multivariate analysis confirmed that CEAP class, vein diameter, adjunctive phlebectomy, and laser wavelength were indeed risk factors for post-EVLA EHIT and that energy delivered and pullback time were not. CONCLUSIONS Water-specific laser fiber wavelength (1470 nm) reduces the risk of EHIT compared with a hemoglobin-specific wavelength (810 nm). CEAP class, simultaneous phlebectomy, and vein diameter >7.5 mm are associated with increased risk of EHIT after EVLA.
