Coinhibitory Pathways in the B7-CD28 Ligand-Receptor Family.

Immune responses need to be controlled for optimal protective immunity and tolerance. Coinhibitory pathways in the B7-CD28 family provide critical inhibitory signals that regulate immune homeostasis and defense and protect tissue integrity. These coinhibitory signals limit the strength and duration of immune responses, thereby curbing immune-mediated tissue damage, regulating resolution of inflammation, and maintaining tolerance to prevent autoimmunity. Tumors and microbes that cause chronic infections can exploit these coinhibitory pathways to establish an immunosuppressive microenvironment, hindering their eradication. Advances in understanding T cell coinhibitory pathways have stimulated a new era of immunotherapy with effective drugs to treat cancer, autoimmune and infectious diseases, and transplant rejection. In this review we discuss the current knowledge of the mechanisms underlying the coinhibitory functions of pathways in the B7-CD28 family, the diverse functional consequences of these inhibitory signals on immune responses, and the overlapping and unique functions of these key immunoregulatory pathways.

Monolithic highly multi-mode XLMA-fiber resonator for high power operation.

Highly multi-mode fiber resonators can be an excellent solution to achieve high output power with homogeneous beam profiles, while nonlinear effects are suppressed due to the high number of modes and high mode-field areas. While highly reflective fiber-Bragg-gratings (HR-FBGs) are a well-developed technology in single-mode fibers, in multi-mode fibers HR-FBGs are under investigation to enable monolithic resonators. Here, we present a monolithic multi-mode fiber resonator in a > 50 µm core diameter XLMA-fiber. We achieve a slope efficiency of up to 50%, stable wavelength operation at 1074 nm and homogeneous beam profiles using an HR-FBG with app. 70% reflectivity.

EndOxy: Mid-term stability and shear stress resistance of endothelial cells on PDMS gas exchange membranes.

Endothelialized oxygenator devices (EndOxy) with a physiological, nonthrombogenic, and anti-inflammatory surface offer the potential to overcome current shortcomings of conventional extracorporeal membrane oxygenation such as complications like thromboembolism and bleeding that deteriorate adequate long-term hemocompatibility. The approach of endothelialization of gas exchange membranes, and thus the formation of a nonthrombogenic and anti-inflammatory surface, is promising. In this study, we investigated the mid-term shear stress resistance as well as gas transfer rates and cell densities of endothelial cells seeded on RGD-conjugated polydimethylsiloxane (RGD-PDMS) gas exchange membranes under dynamic conditions. Human umbilical vein endothelial cells were seeded on RGD-PDMS and exposed to defined shear stresses in a microfluidic bioreactor. Endothelial cell morphology was assessed by bright field microscopy and immunocytochemistry. Furthermore, gas transfer measurement of blank, RGD-conjugated, and endothelialized PDMS oxygenator membranes was performed. RGD-PDMS gas exchange membranes proved suitable for the dynamic culture of endothelial cells for up to 21 days at a wall shear stress of 2.9 dyn/cm2 . Furthermore, the cells resisted increased wall shear stresses up to 8.6 dyn/cm2 after a previous dynamic preculture of each one hour at 2.9 dyn/cm2 and 5.7 dyn/cm2 . Also, after a longer dynamic preculture of three days at 2.9 dyn/cm2 and one hour at 5.7 dyn/cm2 , increased wall shear stresses of 8.6 dyn/cm2 were tolerated by the cells and cell integrity could be remained. Gas transfer (GT) tests revealed that neither RGD conjugation nor endothelialization of RGD-PDMS significantly decrease the gas transfer rates of the membranes during short-term trials. Gas transfer rates are stable for at least 72 hours of dynamic cultivation of endothelial cells. Immunocytochemistry showed that the cell layer stained positive for typical endothelial cell markers CD31 and von Willebrand factor (VWF) after all trials. Cell density of EC on RGD-PDMS increased between 3 and 21 days of dynamic culture. In this study, we show the suitability of RGD-PDMS membranes for flow resistant endothelialization of gas-permeable membranes, demonstrating the feasibility of this approach for a biohybrid lung.

DeepCAGE transcriptomics identify HOXD10 as a transcription factor regulating lymphatic endothelial responses to VEGF-C.

Lymphangiogenesis plays a crucial role during development, in cancer metastasis and in inflammation. Activation of VEGFR-3 (also known as FLT4) by VEGF-C is one of the main drivers of lymphangiogenesis, but the transcriptional events downstream of VEGFR-3 activation are largely unknown. Recently, we identified a wave of immediate early transcription factors that are upregulated in human lymphatic endothelial cells (LECs) within the first 30 to 80 min after VEGFR-3 activation. Expression of these transcription factors must be regulated by additional pre-existing transcription factors that are rapidly activated by VEGFR-3 signaling. Using transcription factor activity analysis, we identified the homeobox transcription factor HOXD10 to be specifically activated at early time points after VEGFR-3 stimulation, and to regulate expression of immediate early transcription factors, including NR4A1. Gain- and loss-of-function studies revealed that HOXD10 is involved in LECs migration and formation of cord-like structures. Furthermore, HOXD10 regulates expression of VE-cadherin, claudin-5 and NOS3 (also known as e-NOS), and promotes lymphatic endothelial permeability. Taken together, these results reveal an important and unanticipated role of HOXD10 in the regulation of VEGFR-3 signaling in lymphatic endothelial cells, and in the control of lymphangiogenesis and permeability.

An Overview of Home-Based Primary Care: Learning from the Field.

ISSUE: Homebound and functionally limited individuals are often unable to access office-based primary care, leading to unmet needs and increased health care spending. GOAL: Show how home-based primary care affects outcomes and costs for Medicare and Medicaid beneficiaries with complex care needs. METHODS: Qualitative synthesis of expert perspectives and the experiences of six case-study sites. FINDINGS AND CONCLUSIONS: Successful home-based primary care practices optimize care by: fielding interdisciplinary teams, incorporating behavioral care and social supports into primary care, responding rapidly to urgent and acute care needs, offering palliative care, and supporting family members and caregivers. Practices participating in Medicare's Independence at Home Demonstration saved $3,070 per beneficiary on average in the first year, primarily by reducing hospital use under this shared-savings program. The experience of a risk-based medical group that contracts with health plans and health systems to provide home-based care suggests similar potential to reduce health care spending under capitated or value-based payment arrangements. Making effective home-based primary care more widely available would require a better-prepared workforce, appropriate financial incentives to encourage more clinicians to provide house calls to their home-limited patients, and relevant quality measures to ensure that value-based payment is calibrated to meet the needs of patients and their families.

Simultaneous frequency stabilization, wavelength multiplexing and improvement of beam quality using a self-optimizing external cavity diode laser.

The combination of a dense wavelength division multiplexer based on volume Bragg gratings (VBGs) and a subsequent feedback mirror forms an efficient single-stage frequency stabilization and multiplexing system. The laser emission of the connected diode laser sources is automatically forced to amplify the wavelengths with the maximum feedback and the minimum losses, respectively. Therefore, different transversal modes of a single emitter may be linked to different wavelength regions that fulfill the Bragg conditions of the VBGs with high efficiency. We demonstrate a multiplexing system with a channel spacing of 1.5 nm and an optical efficiency of 86%, up to 90% being feasible with modifications. The emission bandwidth of the diode laser single emitters is reduced to <300 pm. Due to transversal mode selection, the lateral beam quality factor M2 of the single emitters decreases by a factor of 1.4 on average, compared to the free running sources.

Suppression of cross coupling in an external resonator for a diode laser bar with 19 single emitters.

We present an external cavity in a quasi-Littrow configuration for a diode laser bar with 19 single emitters and the individual spectral stabilization, ranging from wavelengths between 970 and 980 nm corresponding to each emitter. The imaging of the vertical waveguide mode onto a blazed grating acting as a diffractive optical element is realized with a beam transformation system that swaps the vertical and lateral axes. Along with a feedback intensity of <10%, the reduction of the divergence due to a beam expander results in high losses for cross coupling modes. We demonstrate the possibility to suppress cross coupling and that even a process-related small smile error has a positive effect on the quality of the spectral stabilization in a quasi-Littrow configuration.

Models of Care for High-Need, High-Cost Patients: An Evidence Synthesis.

This brief analyzes experts' reviews of evidence about care models designed to improve outcomes and reduce costs for patients with complex needs. It finds that successful models have several common attributes: targeting patients likely to benefit from the intervention; comprehensively assessing patients' risks and needs; relying on evidence-based care planning and patient monitoring; promoting patient and family engagement in self-care; coordinating care and communication among patients and providers; facilitating transitions from the hospital and referrals to community resources; and providing appropriate care in accordance with patients' preferences. Overall, the evidence of impact is modest and few of these models have been widely adopted in practice because of barriers, such as a lack of supportive financial incentives under fee-for-service reimbursement arrangements. Overcoming these challenges will be essential to achieving a higher-performing health care system for this patient population.

What is the societal burden of endometriosis-associated symptoms? a prospective Belgian study.

Endometriosis is a complex disease that affects a large number of women of reproductive age and imposes a significant burden on patients and society. The aim of this study was to evaluate diagnosis, comorbidities, healthcare resource use, treatment patterns, costs and quality of life of women with endometriosis seen in a Belgian tertiary care centre. A total of 134 patients were included in a prospective questionnaire-based cost-of-illness study. Patients were diagnosed after a median delay of 2 years after onset of symptoms. Almost all patients reported having at least one comorbidity. Total annual costs per patient were €9872 (95% confidence interval €7930­11,870), with costs of productivity loss representing 75% of total costs. Hospitalizations, surgeries, infertility treatments, pain and anxiety increased total costs significantly (P 0.001). Patients generated an average of 0.82 QaLY over a 1-year time horizon. This study showed that direct and indirect costs attributable to endometriosis-associated symptoms are substantial. Earlier diagnosis and cost-effective treatment of endometriosis may decrease productivity loss, quality of life impairment and healthcare consumption and consequently reduce total costs to patients and society.

In vivo performance of the VistaProof fluorescence-based camera for detection of occlusal lesions.

OBJECTIVES: The aim of this study was to evaluate the in-vivo performance of the VistaProof fluorescence-based camera (VP) on occlusal surfaces. METHODS: The study was approved by the ethics committee and informed consent was given by the participants. The study included 306 unrestored permanent teeth of 26 patients. The occlusal surfaces of the teeth were examined visually using International Caries Detection and Assessment System (ICDAS) criteria. Then, digital images of the surfaces were made using the VP. The actual depth of the lesions was assessed using radiographs and/or clinically by opening the lesion when appropriate. Correlation between all methods was assessed using Spearman's rank correlation coefficient (r s ). Sensitivity (SE) and specificity (SP) were calculated at D1-(enamel lesions) and D3-(dentine caries) diagnostic threshold and area under the ROC curve (AUC) were assessed. RESULTS: Significant positive correlation was found between ICDAS, VP measurements and the reference standard (r s 0.46-0.71, p < 0.01). SE and SP were at D1-diagnostic threshold level 92.3 and 41.1 %, respectively. At D3-diagnostic threshold, SE was 25.9 % and SP 97.9 %. The diagnostic performance (AUC) was 0.82 (D1) and 0.85 (D3). Combination of VP measurements with ICDAS showed the SE value of 74.1 % at D3-diagnostic threshold. CONCLUSION: The VP showed good diagnostic performance. The combination of VP measurements with ICDAS improved the SE in detecting dentine lesions.

Respondent Demographics and Contraceptive Use Patterns in the United States: A National Survey of Family Growth Analysis.

INTRODUCTION: Contraception is an important tool for helping to prevent both unintended pregnancies and sexually transmitted infections (STIs). Medical costs related to STIs are high and impose a large burden on both patients and the healthcare system. In addition, unintended pregnancies account for a large portion of pregnancies in the United States (US) and are associated with adverse maternal and infant health outcomes. Both STIs and unintended pregnancies are continuous public health concerns, and this study aims to identify patterns in contraceptive method use in relation to specific social determinants of health. METHODS: Utilizing the Centers for Disease Control and Prevention (CDC)'s 2017-2019 National Survey of Family Growth report on current contraceptive status, we isolated data from 3,572 respondents who reported using one of the following contraceptive methods: oral contraceptive pills (OCPs), male condoms, partner's vasectomy, female sterilization, withdrawal, medroxyprogesterone acetate injections (Depo-Provera), hormonal implant, or an intrauterine device (IUD). We analyzed these contraceptive methods among age, race, education, marital status, and insurance status. Data were analyzed in RStudio 2022.02.0 (RStudio Team, RStudio: Integrated Development for R. RStudio, PBC, Boston, MA) through a test of equal proportions for a significance of P < 0.05. A concurrent Yates' continuity correction was performed in order to limit erroneous significant findings based on small sample sizes where applicable. The study conception and data analysis were performed independently with oversight from our preceptor at HCA Florida Brandon Hospital, Brandon, Florida. RESULTS: There were statistically significant differences for all our selected methods of contraception across different age groups. There were statistically significant differences for OCPs, male condoms, partner's vasectomy, female sterilization, Depo-Provera, hormonal implant, and IUD across different race groups and different insurance statuses. There were statistically significant differences for OCPs, male condoms, partner's vasectomy, female sterilization, withdrawal, hormonal implant, and IUD across different education levels and different marital statuses. CONCLUSION: This analysis highlights gaps that are present in female reproductive autonomy through the statistical differences in contraceptive methods across various demographics and warrants continued focus on the role that social determinants of health play in the prevention of unintended pregnancies and STIs. In order to promote fairness and equality in healthcare, it is essential to increase education on these topics both within and beyond medical settings. This effort aims to provide patients with equitable access to healthcare and attempt to address health disparities that are prevalent in multiple different sectors.

Comparison of lidocaine and lidocaine-xylazine for distal paravertebral anesthesia in dairy cattle.

OBJECTIVE: To determine the time of onset and duration of action of distal paravertebral blocks (DPB) in dairy cattle using lidocaine and lidocaine plus xylazine (LX). ANIMALS: 10 healthy adult Holstein cows. METHODS: Unilateral DPB were performed in 6 cows at L1, L2, and L4. They received 2 treatments (lidocaine and LX) in a blinded random crossover design. Due to treatment failure, 4 additional cows were enrolled. The lidocaine treatment received 1,800 mg (90 mL) of lidocaine, and treatment LX received 1,784 mg (89.2 mL) of lidocaine and 16 mg (0.8 mL) of xylazine. Anesthesia was assessed by response (rapid movements of the tail, directed movements of the feet, or turning of the head towards the site of the needle pricks) to 6 approximately 1-cm deep needle pricks to the paralumbar fossa with a 22-gauge hypodermic needle. The time of onset, duration of action, maximum sedation score, and average heart rate (HR) were compared between treatments. RESULTS: Duration of anesthesia was significantly prolonged after DPB in cows treated with LX (251.6 ± 96.94 minutes) compared to lidocaine (105.8 ± 35.9 minutes; P = .01). Treatment with LX was associated with significantly lower average heart rate (56 ± 3 beats/min) compared to cows treated with lidocaine (59 ± 3 beats/min; P = .045). The LX treatment was associated with mild sedation but was not significant (P = .063). CLINICAL RELEVANCE: The addition of xylazine to a lidocaine DPB provides a longer duration of anesthesia, is inexpensive and practical, and can be implemented with ease.

Hypokinetic Biliary Dyskinesia in a Pediatric Patient: A Case Report.

The diagnosis of biliary dyskinesia (BD) in pediatric patients lacks uniformity across the literature. BD is among the most common reasons for cholecystectomy in pediatric patients. Even still, diagnostic criteria for this disorder, including symptomatology and gallbladder ejection fraction, as well as the symptomatic relief after cholecystectomy, are inconsistent across the literature for the pediatric population. We share the case of an 18-year-old female patient who presented to our clinic for cholecystectomy for a diagnosis of BD. After 10 months of seeking a diagnosis, an eventual nuclear medicine HIDA scan revealed a biliary ejection fraction of 18%, leading her to our care. The patient underwent robotic-assisted laparoscopic cholecystectomy and tolerated the procedure well, reporting a resolution of symptoms on follow-up. The diagnosis and management of BD are complicated by the combination of vague and varied symptomatology and a lack of definitive, uniform diagnostic criteria in the pediatric population. Variability in diagnostic requirements varies between sources. While some look to the interpretation of gallbladder emptying studies, others rely on surgical outcomes. To further complicate diagnosis, some patients experience symptoms that do not correlate with their gallbladder emptying studies. The controversy extends beyond diagnosis as some studies argue against cholecystectomy as a treatment for BD, as it has been shown to not always resolve symptoms. More research should be conducted to identify and establish more consistent diagnostic criteria for BD in the pediatric population, as well as to study symptomatic improvement following cholecystectomy to establish optimal treatment for these patients. Biliary dyskinesia is a relatively common but rather inconsistent diagnosis in the pediatric population, and attention should be turned toward developing uniform and consistent diagnostic criteria in order to optimally recognize, diagnose, and treat these patients, ensuring a shorter time-to-diagnosis and improved quality of life.

Appendiceal Endometriosis Presenting As Chronic Appendicitis: A Case Report.

The origin of endometriosis has multiple theories, with controversy over which may demonstrate the prominent pathophysiology. The most common extra-pelvic organ system affected by endometriosis is the gastrointestinal tract. Gastrointestinal endometriosis (GE) accounts for 3 to 37% of all endometriosis cases, and appendiceal endometriosis is present in around 3% of GE cases, therefore constituting less than 1% of all endometriosis cases. In this report, we present a 24-year-old female with a past medical history significant for endometriosis status post two excisional laparoscopies who presented with eight months' duration of right lower quadrant pain, constant and stabbing, with rebound tenderness. Appendectomy and histopathology demonstrated focal endometriosis, diffuse serosal fibrovascular adhesions involving the appendiceal serosa/subserosa, as well as a dilated lumen filled with hemorrhagic content. When the appendix is not considered in endometriosis pathology, patients are at increased risk for unresolved pain and further laparoscopic procedures. Prophylactic appendectomy appears to be a worthwhile consideration in patients with chronic pelvic pain, given the high frequency of appendiceal pathology.

Urolithin A as a Potential Agent for Prevention of Age-Related Disease: A Scoping Review.

The aging of an organism is hallmarked by systemic loss of functional tissue, resulting in increased fragility and eventual development of age-related neurodegenerative, musculoskeletal, cardiovascular, and neoplastic diseases. Growing scientific evidence points to mitochondrial dysfunction as a key contributor in the aging process and subsequent development of age-related pathologies. Under normal physiologic conditions, the body removes dysfunctional mitochondria via an autophagic process known as mitophagy. Urolithin A (UA), a metabolite produced when gut microflora digests the polyphenol compounds ellagitannin and ellagic acid, is a known inducer of mitophagy via several identified mechanisms of action. The primary objective of this scoping review is to identify and summarize the clinical relevance of UA supplementation in the prevention of age-related pathology and diseases. A computer-assisted literature review was performed using PubMed and EMBASE for primary source research articles examining UA supplementation and aging-related pathologies. A total of 293 articles were initially identified from a database search, and 15 articles remained for inclusion in this review, based on predetermined criteria. Analysis of the 15 identified publications demonstrated that UA holds potential as a dietary intervention for slowing the progression of aging and preventing the development of age-related disease. This review also illustrates the potential role that mitochondrial health and inflammation play in the progression of age-related pathology. Identifying the clinical relevance of UA supplementation in the prevention of age-related pathology and diseases will help further the focus of research on treatments that may improve the longevity and quality of life in patients at risk for these comorbidities.

An Immunohistochemical Anomaly: A Case Report and Systematic Review of Myofibroblastoma of the Breast.

Myofibroblastoma (MFB) is a rare but benign mesenchymal tumor most commonly appearing within breast tissue. Most cases of MFB occur in postmenopausal women and are treated by surgical excision. The diagnosis of MFB is made through immunohistochemical (IHC) analysis, with the most common biomarkers being CD34+, desmin+, smooth muscle actin+, and vimentin+. In this article, we describe a case of an MFB in a premenopausal female with variance from classic IHC findings. We also performed a systemic review of the MFB of the breast. The systemic review compiles the most common IHC findings of MFB, patient demographics, treatment methods, lesion size, and the presence or absence of pain associated with the lesion. As MFB can share many features with other breast lesions, including potentially malignant ones, this article sought to underline the most common IHC findings and characteristics of MFB to aid in the proper diagnosis of MFB.

Influence of Aerosolization on Endothelial Cells for Efficient Cell Deposition in Biohybrid and Regenerative Applications.

The endothelialization of gas exchange membranes can increase the hemocompatibility of extracorporeal membrane oxygenators and thus become a long-term lung replacement option. Cell seeding on large or uneven surfaces of oxygenator membranes is challenging, with cell aerosolization being a possible solution. In this study, we evaluated the endothelial cell aerosolization for biohybrid lung application. A Vivostat® system was used for the aerosolization of human umbilical vein endothelial cells with non-sprayed cells serving as a control. The general suitability was evaluated using various flow velocities, substrate distances and cell concentrations. Cells were analyzed for survival, apoptosis and necrosis levels. In addition, aerosolized and non-sprayed cells were cultured either static or under flow conditions in a dynamic microfluidic model. Evaluation included immunocytochemistry and gene expression via quantitative PCR. Cell survival for all tested parameters was higher than 90%. No increase in apoptosis and necrosis levels was seen 24 h after aerosolization. Spraying did not influence the ability of the endothelial cells to form a confluent cell layer and withstand shear stresses in a dynamic microfluidic model. Immunocytochemistry revealed typical expression of CD31 and von Willebrand factor with cobble-stone cell morphology. No change in shear stress-induced factors after aerosolization was reported by quantitative PCR analysis. With this study, we have shown the feasibility of endothelial cell aerosolization with no significant changes in cell behavior. Thus, this technique could be used for efficient the endothelialization of gas exchange membranes in biohybrid lung applications.

Non-steroidal Anti-inflammatory Drugs and Osteopathic Manipulative Treatment for Pain Management in Patients With Osteoarthritis: A Literature Review.

The pathophysiology of osteoarthritis (OA) involves the destruction of articular cartilage and the overgrowth of bone with lipping and spur formation. Nerve endings in the joint capsule and adjacent tissues play a major role in the pain mechanisms of osteoarthritis. This often requires patients to seek pain control measures beyond over-the-counter drugs, such as local anesthetics. Osteopathic manipulation treatment (OMT) is a conservative, non-pharmacological treatment that can be used to help treat chronic pain associated with OA. Other non-pharmacologic therapies include weight loss, exercise, physical therapy (PT), and assistive devices. However, pharmacologic management may be added synergistically to control flares and maintain baseline activities of daily living. While oral non-steroidal anti-inflammatory drugs (NSAIDs) have been the mainstay of treatment for pain and inflammation associated with OA, they have a non-selective inhibitory action that often results in negative side effects when used chronically. The possibility of minimizing these complications through alternate treatments such as topical NSAIDs provides an opportunity for patients to receive adequate pain relief from OA without suffering unnecessary consequences. This literature review seeks to assess the state of research regarding topical NSAIDs and OMT as alternatives to the current gold-standard treatment of OA. The significant inclusion criteria consisted of articles that described the effects of OMT on OA or the use of topical NSAIDs such as Voltaren on OA. Due to the limited articles found, a qualitative analysis was performed, and the salient conclusions are outlined. Alternative pharmacological and non-pharmacological treatments, such as topical diclofenac gel and OMT, have shown promising results in the treatment of pain in OA. It is seen that a majority of patients achieve pain management using NSAIDs, acetaminophen, or topical analgesics. Both diclofenac sodium and OMT have individually been shown to be effective treatments of OA when compared to the use of oral NSAIDs. A holistic treatment approach that utilizes both topical diclofenac sodium and OMT may provide OA patients with an effective option to reduce their moderate to severe chronic pain with limited side effects. Further, high-quality randomized controlled trials are needed to identify whether synergistic effects occur when combining diclofenac sodium gel and OMT for pain relief in patients with OA.

Exploring the interagency collaboration between a pediatric oncology health care setting and community schools.

Globally, approximately 400,000 youth are diagnosed with pediatric cancer each year. Treatment-related side effects, psychosocial challenges, and frequent school absences may adversely impact learning and the education experience among these youth. Efforts to enhance interagency collaboration between health care settings and community schools are imperative to facilitate school reintegration. The Standards for the Psychosocial Care of Children with Cancer and Their Families outline specific guidelines related to the continuity of education for students impacted by pediatric cancer. In particular, the Academic Continuity and School Reentry Support and Monitoring and Assessment of Neuropsychological Outcomes standards of care highlighted within this article align with extant programmatic efforts for transitioning hospitalized school-aged children back into community schools. This article aims to describe systematic programmatic efforts within hospital-based psychosocial programs that are consistent with the Standards for the Psychosocial Care of Children with Cancer and Their Families, as well as interagency collaboration with community schools to support student-centered education for youth impacted by pediatric cancer. Resources for school psychologists, teachers, hospital-based programs, and others involved in student-centered education for pediatric cancer patients and survivors are presented.

Support for Community School Personnel Working with Pediatric Cancer Patients: A Quality Improvement Initiative.

Improved therapies and increased survival rates are sending more pediatric cancer patients and survivors back to their classrooms; however, most community school personnel lack training or experience in working with these students. The aim of this quality improvement project was twofold: (a) to evaluate community school personnel's perceptions of their preparedness to work with patients and childhood cancer survivors who have reentered the classroom; and (b) to standardize school reentry supports to improve community school personnel preparedness. Twenty community school personnel, prekindergarten through 12-grade teachers, guidance counselors, and administrators, who had previously worked with a pediatric cancer patient were surveyed regarding their experiences with the patient's school reentry. Responses were coded and analyzed, and a thematic map was created. School personnel reported concerns related to student functioning, such as academic readiness, cognitive impacts of treatment, social-emotional adjustment, physical ability to participate in school, and medical fragility. They also reported concerns related to their own ability to accommodate the student's needs. These results were used to design educational guides for community personnel consisting of information and resources to support them in managing the unique academic, social-emotional, physical, and medical needs of pediatric cancer patients and survivors in the classroom.
