Yoga as a non-pharmacologic therapy to reduce dinutuximab-induced pain in patients with neuroblastoma.

BACKGROUND: Anti-GD2 antibodies are key components of treatment for high-risk neuroblastoma; however, they cause neuropathic pain. Yoga therapy may help reduce pain and distress associated with anti-GD2 therapy. PROCEDURE: Children 3 years of age or older with neuroblastoma participated in individualized yoga therapy while receiving the anti-GD2 antibody dinutuximab (DIN). Yoga therapy was deemed feasible if patients participated during 60% or more of DIN admissions. Patients and caregivers assessed pain/distress before and after yoga therapy with a distress thermometer (DT) and Wong-Baker FACES pain rating scale and completed questionnaires regarding satisfaction with yoga therapy. Therapy was deemed efficacious if there was a ≥1 point pain score change and reduction in distress after yoga. RESULTS: Eighteen patients were enrolled; 52 encounters (admissions for DIN) were evaluable. Ten of 18 were female, three of 18 were Hispanic, and 10/18 were White. Median age at enrollment was 5.5 years (range: 3-11). Yoga therapy was feasible in 39/52 (75%) encounters. Significant reductions in caregiver-reported pain and distress and reductions in patient-reported pain and distress after yoga therapy were reported. Twelve of 18 caregivers completed questionnaires: seven agreed/strongly agreed that yoga was valuable, and nine agreed/strongly agreed to continued participation in yoga. Thirty-four of 36 clinicians reported that they would recommend yoga therapy for other patients receiving DIN. CONCLUSIONS: Yoga therapy was feasible during DIN therapy and may be effective in reducing DIN-associated pain and distress. Future studies are needed to evaluate changes in opioid usage with the addition of yoga therapy during anti-GD2 antibody therapy.

Transmission of Spinach Downy Mildew via Seed and Infested Leaf Debris.

Spinach downy mildew, caused by the obligate oomycete pathogen Peronospora effusa, is a worldwide constraint on spinach production. The role of airborne sporangia in the disease cycle of P. effusa is well established, but the role of the sexual oospores in the epidemiology of P. effusa is less clear and has been a major challenge to examine experimentally. To evaluate seed transmission of spinach downy mildew via oospores in this study, isolated glass chambers were employed in two independent experiments to grow out oospore-infested spinach seed and noninfested seeds mixed with oospore-infested crop debris. Downy mildew diseased spinach plants were observed 37 and 34 days after planting in the two isolator experiments, respectively, in the chambers that contained one of two oospore-infested seed lots or seeds coated with oospore-infested leaves. Spinach plants in isolated glass chambers initiated from seeds without oospores did not show downy mildew symptoms. Similar findings were obtained using the same seed lot samples in a third experiment conducted in a growth chamber. In direct grow out tests to examine oospore infection on seedlings performed in a containment greenhouse with oospore-infested seed of two different cultivars, characteristic Peronospora sporangiophores were observed growing from a seedling of each cultivar. The frequency of seedlings developing symptoms from 82 of these oospore-infested seed indicated that approximately 2.4% of seedlings from infested seed developed symptoms, and 0.55% of seedlings from total seeds assayed developed symptoms. The results provide evidence that oospores can serve as a source of inoculum for downy mildew and provide further evidence of direct seed transmission of the downy mildew pathogen to seedlings in spinach via seedborne oospores.

Understanding the Genotypic and Phenotypic Structure and Impact of Climate on Phytophthora nicotianae Outbreaks on Potato and Tomato in the Eastern United States.

Samples from potato fields with lesions with late blight-like symptoms were collected from eastern North Carolina in 2017 and the causal agent was identified as Phytophthora nicotianae. We have identified P. nicotianae in potato and tomato samples from North Carolina, Virginia, Maryland, Pennsylvania, and New York. Ninety-two field samples were collected from 46 fields and characterized for mefenoxam sensitivity, mating type, and simple sequence repeat genotype using microsatellites. Thirty-two percent of the isolates were the A1 mating type, while 53% were the A2 mating type. In six cases, both A1 and A2 mating types were detected in the same field in the same year. All isolates tested were sensitive to mefenoxam. Two genetic groups were discerned based on STRUCTURE analysis: one included samples from North Carolina and Maryland, and one included samples from all five states. The data suggest two different sources of inoculum from the field sites sampled. Multiple haplotypes within a field and the detection of both mating types in close proximity suggests that P. nicotianae may be reproducing sexually in North Carolina. There was a decrease in the average number of days with weather suitable for late blight, from 2012 to 2016 and 2017 to 2021 in all of the North Carolina counties where P. nicotianae was reported. P. nicotianae is more thermotolerant than P. infestans and grows at higher temperatures (25 to 35°C) than P. infestans (18 to 22°C). Late blight outbreaks have decreased in recent years and first reports of disease are later, suggesting that the thermotolerant P. nicotianae may cause more disease as temperatures rise due to climate change.

Phytophthora capsici, 100 Years Later: Research Mile Markers from 1922 to 2022.

In 1922, Phytophthora capsici was described by Leon Hatching Leonian as a new pathogen infecting pepper (Capsicum annuum), with disease symptoms of root rot, stem and fruit blight, seed rot, and plant wilting and death. Extensive research has been conducted on P. capsici over the last 100 years. This review succinctly describes the salient mile markers of research on P. capsici with current perspectives on the pathogen's distribution, economic importance, epidemiology, genetics and genomics, fungicide resistance, host susceptibility, pathogenicity mechanisms, and management.

Mixed Study Systematic Review and Meta-analysis of Sexuality and Sexual Rehabilitation in LGBTQI+ Adults Living With Chronic Disease.

OBJECTIVE: To systematically review how sexuality is experienced by lesbian, gay, bisexual, transgender, queer or questioning, intersex plus (other gender identifies and sexual orientations) (LGBTQI+) persons living with chronic disease. DATA SOURCES: PsycINFO, Embase, MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health, and Web of Science were searched from date of inception to November 2021 for English language publications. Reference lists of relevant publications were also searched. STUDY SELECTION: Eligible studies reported on sexuality among LGBTQI+ persons living with chronic disease. The search yielded 12,626 records; 665 full texts were assessed for eligibility and 63 documents included (59 unique studies). Study quality was rated using the Mixed Methods Appraisal Tool. DATA EXTRACTION: Characteristics of included studies were recorded independently by 2 authors. Differences were resolved through discussion or with a third author. DATA SYNTHESIS: A sequential, exploratory mixed-studies approach was used for synthesis. Pooled analysis indicated that among gay and bisexual men living with prostate cancer, 68.3% experienced erectile dysfunction and 62.9% had insufficient quality of erection to engage in anal sex. Among gay and bisexual men living with HIV or AIDS, 29.3% experienced loss of libido and 25.3% experienced erectile dysfunction. Although sexual dysfunction was common, LGBTQI+ persons had difficulty accessing appropriate sexual counseling and identified negative attitudes and heteronormative assumptions by health care providers as significant barriers to sexual health. Interventions to address sexuality focused entirely on reduction of risky sexual behavior among men living with HIV or AIDS. Women, transgender persons, and intersex persons were largely excluded from the research studies. CONCLUSIONS: Current understandings of the effect of chronic disease on LGBTQI+ sexuality are limited and mostly focus on the male sexual response. LGBTQI+ persons who experience difficulty with sexuality struggle to identify appropriate services, and there is an absence of evidence-based interventions to promote sexual health and well-being in this population.

Chronic frontal neurobehavioural symptoms in combat-deployed military personnel with and without a history of blast-related mild traumatic brain injury.

OBJECTIVE: This study evaluated frontal behavioural symptoms, via the FrSBe self-report, in military personnel with and without a history of blast-related mild traumatic brain injury (mild TBI). METHODS: Prospective observational cohort study of combat-deployed service members leveraging 1-year and 5-year demographic and follow up clinical outcome data. RESULTS: The blast mild TBI group (n = 164) showed greater frontal behavioural symptoms, including clinically elevated apathy, disinhibition, and executive dysfunction, during a 5-year follow-up, compared to a group of combat-deployed controls (n = 107) without mild TBI history or history of blast exposure. We also explored changes inbehaviourall symptoms over a 4-year span, which showed clinically significant increases in disinhibition in the blast mild TBI group, whereas the control group did not show significant increases in symptoms over time. CONCLUSION: Our findings add to the growing evidence that a proportion of individuals who sustain mild TBI experience persistent behavioural symptoms. We also offer a demonstration of a novel use of the FrSBe as a tool for longitudinal symptom monitoring in a military mild TBI population.

Efficacy of Organic Fungicides for Downy Mildew in Field-Grown Sweet Basil.

Downy mildew is a common, widespread disease affecting basil leaves. No tolerance for disease symptoms, especially on leaves for fresh consumption, necessitates management. Six replicated experiments were conducted between 2010 and 2016 with field-grown basil of a susceptible cultivar exposed to naturally occurring, wind-dispersed sporangiospores of Peronospora belbahrii to evaluate fungicides approved for use on organically produced crops and products in development. Products tested currently registered for use on basil in the U.S. and labeled for downy mildew were Actinovate (Streptomyces lydicus), Companion (Bacillus subtilis), Cueva (copper octanoate), Double Nickel (Bacillus amyloliquefaciens), Forticept EP #1 (thyme oil), Milagrum Plus (Bacillus subtilis), Organocide (sesame oil), Oso (polyoxin D zinc salt), OxiDate (hydrogen dioxide), Procidic (citric acid), Regalia (Reynoutria sachalinensis extract), Stargus (Bacillus amyloliquefaciens), and Trilogy (neem oil). Most are biopesticides. A conventional fungicide, Revus (mandipropamid), was included in most experiments as a positive control. Applications were made weekly to foliage with a backpack sprayer starting before symptoms were seen, except in 2013 when disease onset was early and 2015 when applications were made twice weekly. Organic treatments tested in 2013 started with a soil drench application around the base of plants two days after transplantation. Fungicide efficacy was assessed based on incidence of symptomatic leaves rather than disease severity because there is no tolerance for disease on fresh-market herbs. None were effective based on weekly severity assessments or AUDPC values, confirming results from other researchers that downy mildew cannot be effectively managed with organic fungicides applied to susceptible basil cultivars.

Providing culturally appropriate residential dementia care for older adults with an Indian heritage: Perspectives from Sydney-based stakeholders.

BACKGROUND AND OBJECTIVES: Global migration and an increased life expectancy led to a growing number of people with dementia from Culturally and Linguistically Diverse (CaLD) backgrounds living in long-term residential care settings. These minority groups' wellbeing may be negatively impacted due to poor culturally appropriate care that fails to honour valued cultural traditions. This study considered culturally appropriate dementia care for older adults with an Indian heritage living in Sydney-based residential aged care facilities. RESEARCH DESIGN AND METHODS: The Nominal Group Technique was employed to collect data from three groups of stakeholders of Indian heritage over a period of 6 months: care staff (n = 8), family of residential care recipients (n = 8), and community-dwelling older adults (n = 7). RESULTS: Perspectives highlighted six concepts for consideration: (1) embracing a person-centred approach to promote culturally appropriate dementia care; (2) training staff in culturally appropriate forms of respect; (3) the impact of staff ratios on care; (4) the importance of familiarity to meaningful engagement; (5) the importance of food; and (6) the necessity of engaging family and the wider Indian community in residential care activities. CONCLUSIONS: Culturally appropriate dementia care for older adults with an Indian heritage is an area in need of further development. To ensure that residents with an Indian heritage are respected as an ethnic minority, it remains crucial that research is generated to inform policy development on each CaLD group as a separate entity.

De novo epilepsy after microsurgical resection of brain arteriovenous malformations.

OBJECTIVE: Seizures are the second most common presenting symptom of brain arteriovenous malformations (bAVMs) after hemorrhage. Risk factors for preoperative seizures and subsequent seizure control outcomes have been well studied. There is a paucity of literature on postoperative, de novo seizures in initially seizure-naïve patients who undergo resection. Whereas this entity has been documented after craniotomy for a wide variety of neurosurgically treated pathologies including tumors, trauma, and aneurysms, de novo seizures after bAVM resection are poorly studied. Given the debilitating nature of epilepsy, the purpose of this study was to elucidate the incidence and risk factors associated with de novo epilepsy after bAVM resection. METHODS: A retrospective review of patients who underwent resection of a bAVM over a 15-year period was performed. Patients who did not present with seizure were included, and the primary outcome was de novo epilepsy (i.e., a seizure disorder that only manifested after surgery). Demographic, clinical, and radiographic characteristics were compared between patients with and without postoperative epilepsy. Subgroup analysis was conducted on the ruptured bAVMs. RESULTS: From a cohort of 198 patients who underwent resection of a bAVM during the study period, 111 supratentorial ruptured and unruptured bAVMs that did not present with seizure were included. Twenty-one patients (19%) developed de novo epilepsy. One-year cumulative rates of developing de novo epilepsy were 9% for the overall cohort and 8.5% for the cohort with ruptured bAVMs. There were no significant differences between the epilepsy and no-epilepsy groups overall; however, the de novo epilepsy group was younger in the cohort with ruptured bAVMs (28.7 ± 11.7 vs 35.1 ± 19.9 years; p = 0.04). The mean time between resection and first seizure was 26.0 ± 40.4 months, with the longest time being 14 years. Subgroup analysis of the ruptured and endovascular embolization cohorts did not reveal any significant differences. Of the patients who developed poorly controlled epilepsy (defined as Engel class III-IV), all had a history of hemorrhage and half had bAVMs located in the temporal lobe. CONCLUSIONS: De novo epilepsy after bAVM resection occurs at an annual cumulative risk of 9%, with potentially long-term onset. Younger age may be a risk factor in patients who present with rupture. The development of poorly controlled epilepsy may be associated with temporal lobe location and a delay between hemorrhage and resection.

First Report of Bacterial Blight on arugula (Eruca vesicaria subsp. sativa) caused by Pseudomonas cannabina pv. alisalensis in New York.

Bacterial blight of arugula (Eruca vesicaria subsp. sativa cv. Standard) was observed in a commercial crop being grown in a high tunnel under overhead irrigation in Argyle, NY in January 2021. Approximately 80-100% of the plants were affected. Symptoms started as small, angular, water-soaked lesions visible on both sides of the leaves, then expanded, coalesced and later dried and turned tan. Fluorescent pseudomonads from five different plants were isolated on King's medium B agar amended with boric acid, chloramphenicol, and cycloheximide (Schaad et al. 2001) from surface disinfested symptomatic leaf tissues macerated in phosphate buffer (10mM, pH 7.0). Five representative isolates from each of the five plants produced levan and were negative for arginine dihydrolase and oxidase. They did not rot potatoes but were able to induce a hypersensitive reaction on tobacco (Nicotiana tabacum L. cv Glurk) within 24 h, thus demonstrating that the isolates belonged to LOPAT group 1 (Lelliott et al. 1966). DNA fragment banding patterns of these isolates generated by repetitive extragenic palindromic sequence PCR (repPCR) with BOXA1R primers were compared to the pathotype strains of Pseudomonas cannabina pv. alisalensis and Pseudomonas syringae pv. maculicola, known fluorescent pathogens of the Brassicaceae. The repPCR banding pattern of all isolates matched the pattern of Pseudomonas cannabina pv. alisalensis. Bacterial inoculum for pathogenicity experiments was prepared from 48 h KBBC agar cultures suspended in phosphate buffer (10mM, pH 7.0) and adjusted to 0.6 optical density at 600nm yielding approximately 108 CFU/ml. Five-week-old arugula plants were sprayed until run-off with one of the three isolates from arugula, a negative control (sterile buffer), or a positive control (P. cannabina pv. alisalensis) that is pathogenic to crucifers and also reported to cause disease on arugula in California (Bull et al. 2004). Experiments consisted of three replications of each treatment and two independent experiments were conducted. Small water-soaked spots resembling the original symptoms developed on all plants inoculated with the three representative isolates and P. cannabina pv. alisalensis. Moreover, reisolates from the symptomatic tissues were fluorescent on KBBC and had identical repPCR banding pattern as inoculated strains, demonstrating Koch's postulates. To our knowledge, this is the first report of bacterial blight on arugula caused by Pseudomonas cannabina pv. alisalensis in the Northeastern US. It was previously reported in California, Nevada, and Minnesota (Bull and du Toit 2009; Bull et al. 2004). This report may have significance for all brassica leafy green growers in the Northeast as P. cannabina pv. alisalensis has a broad host range including members of the Brassicaceae and oats which are commonly used as cover crops in mixed vegetable production.

'Doing' dating: A cross-sectional survey of young adults (18-35 years) in Australia and Hong Kong.

INTRODUCTION: Dating is an occupation through which people form intimate relationships with others. Despite the importance of intimate relationships for wellbeing, there is limited information available in occupational therapy literature about the activities involved in dating and little guidance for practitioners who wish to support clients from diverse backgrounds who experience difficulties with dating. To address this gap, this study sought to explore dating among young adults (18-35 years) and compare dating activities between two contexts: Australia and Hong Kong. METHODS: Data were collected using an e-survey designed for this study and refined using cognitive interviewing (n = 12). It included questions about dating initiation and activities. Study design and reporting was guided by the Checklist for Reporting Results of Internet E-Surveys. Data were analysed using descriptive statistics and between group comparisons. Reponses to open ended questions were subjected to interpretative content analysis and quantified. RESULTS: In total, 2208 young adults aged 18-35 who had at least one dating experience and resided in either Australia or Hong Kong completed the survey. Participants met their dates most commonly through school, friends, dating apps, and work. The most frequent ways to ask a person on a date were by suggesting 'hanging out' or going out for food, drink or to the movies. Most participants reported that organising a date required extended negotiation between the parties. Differences were found between participants from Hong Kong and Australia. CONCLUSIONS: This is the first study of contemporary dating from an occupational perspective and provides an understanding of dating activities in two different cultural contexts.

The parenting occupations and purposes conceptual framework: A scoping review of 'doing' parenting.

INTRODUCTION: Parenting is a valued, common and challenging adult role. Many parents, including some living with disability or difficult social circumstances, experience barriers to fulfilling their parenting roles. Yet, occupational therapy involvement in parenting is rarely documented. Current understandings about 'doing' parenting lack cohesion and are dispersed in occupational therapy literature. This study aims to map and synthesise occupational therapy literature on 'doing' parenting to describe the state of the existing knowledge base, and develop a conceptual framework of parenting occupations as portrayed in occupational therapy literature. METHODS: A scoping review was conducted. Medline, EMBASE, CINAHL, PsycINFO, Scopus, and Web of Science were searched on 28 October 2019 and updated on 18 February 2021. Journal articles and book chapters were screened for eligibility. Included texts' publication characteristics, methodological characteristics, and areas of focus were summarised. Interpretive content analysis was conducted. RESULTS: From 5945 unique records, 105 texts were included. These discussed general parenting, parents with disabilities, and parenting in challenging social situations. Most texts focussed on mothers caring for young children in Western cultural contexts. The analysis culminated in the development of a conceptual framework: the Parenting Occupations and Purposes (POP) Framework. This comprises 10 interrelated areas of parenting occupations, which are performed for the purposes of addressing the child's basic, developmental and social needs. Parenting occupations were also found to be influenced by additional, underlying occupations that build parenting capacity - Continuous Parental Development (CPD) occupations. CONCLUSION: These findings provide an overview of current occupational therapy conceptualisations of parenting. Unlike most of the existing literature on parenting, the POP Framework is parent-centric rather than child-centric. More research on parenting occupations is needed, especially with more diverse representation (fathers, ages of children, parental disability and sociocultural background). Further research is required to examine the POP Framework's usefulness in guiding research and practice, particularly among parents with diverse characteristics.

Addressing Sexuality Among People Living With Chronic Disease and Disability: A Systematic Mixed Methods Review of Knowledge, Attitudes, and Practices of Health Care Professionals.

OBJECTIVE: To systematically review health care professionals' practices and attitudes toward addressing sexuality with people who are living with chronic disease and disability. DATA SOURCES: Scopus, PubMed, PsycINFO, Cumulative Index to Nursing and Allied Health, Allied and Complementary Medicine Database, and MEDLINE were searched to August 2020 for English language publications. Reference lists of relevant publications were also searched. STUDY SELECTION: Eligible studies reported on knowledge, attitudes, and behaviors of health care professionals about addressing sexuality in the context of chronic disease and disability. The search yielded 2492 records; 187 full texts were assessed for eligibility and 114 documents were included (103 unique studies). Study quality was rated using the Mixed Methods Appraisal Tool. DATA EXTRACTION: Characteristics of included studies were recorded independently by 2 authors. Differences were resolved through discussion or by a third author. DATA SYNTHESIS: A sequential, exploratory mixed studies approach was used for synthesis. Pooled analysis showed that 14.2% (95% CI, 10.6-18.9 [I2=94.8%, P<.001]) of health professionals report routinely asking questions or providing information about sexuality. Professionals reported limited confidence, competence, and/or comfort when initiating conversations about sexuality or responding to patient questions. Sexual rehabilitation typically focused on the effect of disease, disability, and medication on sexual function. Broader dimensions of sexuality were rarely addressed. CONCLUSION: Despite recognizing the value of sexuality to health and well-being, most health professionals regardless of clinical context fail to routinely include assessment of sexuality in their practice. Professionals have limited knowledge and confidence when addressing sexuality and experience significant discomfort when raising this topic with people living with chronic disease and disability. Multicomponent implementation programs are needed to improve health professionals' knowledge, competence, and comfort when addressing sexuality for people living with chronic disease and disability.

Impact of surgeon rhBMP-2 cost awareness on complication rates and health system costs for spinal arthrodesis.

OBJECTIVE: Recombinant human bone morphogenetic protein-2 (rhBMP-2) is used in spinal arthrodesis procedures to enhance bony fusion. Research has suggested that it is the most cost-effective fusion enhancer, but there are significant upfront costs for the healthcare system. The primary objective of this study was to determine whether intraoperative dosing and corresponding costs changed with surgeon cost awareness. The secondary objective was to describe surgical complications before and after surgeon awareness of rhBMP-2 cost. METHODS: A retrospective medical record review was conducted to identify patients who underwent spinal arthrodesis procedures performed by a single surgeon, supplemented with rhBMP-2, from June 2016 to June 2018. Collected data included rhBMP-2 dosage, rhBMP-2 list price, and surgical complications. Expected Medicare reimbursement was calculated. Data were analyzed before and after surgeon awareness of rhBMP-2 cost. RESULTS: Forty-eight procedures were performed using rhBMP-2, 16 before and 32 after surgeon cost awareness. Prior to cost awareness, the most frequent rhBMP-2 dosage level was x-small (38.9%, n = 7), followed by large (27.8%, n = 5) and small (22.2%, n = 4). After cost awareness, the most frequent rhBMP-2 dosage was xx-small (56.8%, n = 21), followed by x-small (21.6%, n = 8) and large (13.5%, n = 5). The rhBMP-2 average cost per surgery was $4116.56 prior to surgeon cost awareness versus $2268.38 after. Two complications were observed in the pre-cost awareness surgical group; 2 complications were observed in the post-cost awareness surgical group. CONCLUSIONS: Surgeon awareness of rhBMP-2 cost resulted in use of smaller rhBMP-2 doses, decreased rhBMP-2 cost per surgery, and decreased overall hospital admission charges, without a detectable increase in surgical complications.

Cellular allograft for multilevel stand-alone anterior cervical discectomy and fusion.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is the most common treatment for degenerative disease of the cervical spine. Given the high rate of pseudarthrosis in multilevel stand-alone ACDF, there is a need to explore the utility of novel grafting materials. In this study, the authors present a single-institution retrospective study of patients with multilevel degenerative spine disease who underwent multilevel stand-alone ACDF surgery with or without cellular allograft supplementation. METHODS: In a prospectively collected database, 28 patients who underwent multilevel ACDF supplemented with cellular allograft (ViviGen) and 25 patients who underwent multilevel ACDF with decellularized allograft between 2014 and 2020 were identified. The primary outcome was radiographic fusion determined by a 1-year follow-up CT scan. Secondary outcomes included change in Neck Disability Index (NDI) scores and change in visual analog scale scores for neck and arm pain. RESULTS: The study included 53 patients with a mean age of 53 ± 0.7 years who underwent multilevel stand-alone ACDF encompassing 2.6 ± 0.7 levels on average. Patient demographics were similar between the two cohorts. In the cellular allograft cohort, 2 patients experienced postoperative dysphagia that resolved by the 3-month follow-up. One patient developed cervical radiculopathy due to graft subsidence and required a posterior foraminotomy. At the 1-year CT, successful fusion was achieved in 92.9% (26/28) of patients who underwent ACDF supplemented with cellular allograft, compared with 84.0% (21/25) of patients who underwent ACDF without cellular allograft. The cellular allograft cohort experienced a significantly greater improvement in the mean postoperative NDI score (p < 0.05) compared with the other cohort. CONCLUSIONS: Cellular allograft is a low-morbidity bone allograft option for ACDF. In this study, the authors determined favorable arthrodesis rates and functional outcomes in a complex patient cohort following multilevel stand-alone ACDF supplemented with cellular allograft.

Progress in diffuse intrinsic pontine glioma: advocating for stereotactic biopsy in the standard of care.

Diffuse intrinsic pontine glioma (DIPG) is a universally fatal pediatric brainstem tumor affecting approximately 300 children in the US annually. Median survival is less than 1 year, and radiation therapy has been the mainstay of treatment for decades. Recent advances in the biological understanding of the disease have identified the H3K27M mutation in nearly 80% of DIPGs, leading to the 2016 WHO classification of diffuse midline glioma H3K27M-mutant, a grade IV brainstem tumor. Developments in epigenetic targeting of transcriptional tendencies have yielded potential molecular targets for clinical trials. Chimeric antigen receptor T cell therapy has also shown preclinical promise. Recent clinical studies, including prospective trials, have demonstrated the safety and feasibility of pediatric brainstem biopsy in the setting of DIPG and other brainstem tumors. Given developments in the ability to analyze DIPG tumor tissue to deepen biological understanding of this disease and develop new therapies for treatment, together with the increased safety of stereotactic brainstem biopsy, the authors present a case for offering biopsy to all children with suspected DIPG. They also present their standard operative techniques for image-guided, frameless stereotactic biopsy.

Pediatric functional hemispherectomy: operative techniques and complication avoidance.

Functional hemispherectomy/hemispherotomy is a disconnection procedure for severe medically refractory epilepsy where the seizure foci diffusely localize to one hemisphere. It is an improvement on anatomical hemispherectomy and was first performed by Rasmussen in 1974. Less invasive surgical approaches and refinements have been made to improve seizure freedom and minimize surgical morbidity and complications. Key anatomical structures that are disconnected include the 1) internal capsule and corona radiata, 2) mesial temporal structures, 3) insula, 4) corpus callosum, 5) parietooccipital connection, and 6) frontobasal connection. A stepwise approach is indicated to ensure adequate disconnection and prevent seizure persistence or recurrence. In young pediatric patients, careful patient selection and modern surgical techniques have resulted in > 80% seizure freedom and very good functional outcome. In this report, the authors summarize the history of hemispherectomy and its development and present a graphical guide for this anatomically challenging procedure. The use of the osteoplastic flap to improve outcome and the management of hydrocephalus are discussed.

Laser interstitial thermal therapy for pediatric atypical teratoid/rhabdoid tumor: case report.

Herein, the authors describe the successful use of laser interstitial thermal therapy (LITT) for management of metastatic craniospinal disease for biopsy-proven atypical teratoid/rhabdoid tumor in a 16-month-old boy presenting to their care. Specifically, LITT was administered to lesions of the right insula and left caudate. The patient tolerated 2 stages of LITT to the aforementioned lesions without complication and with evidence of radiographic improvement of lesions at the 2- and 6-month follow-up appointments. To the authors' knowledge, this represents the first such published report of LITT for management of atypical teratoid/rhabdoid tumor.

Efficacy of Conventional Fungicides for Downy Mildew in Field-Grown Sweet Basil in the United States.

Application of fungicides has been the main management practice for Peronospora belbahrii, which is the most important pathogen of sweet basil in the United States. Six replicated experiments were conducted between 2010 and 2016 with field-grown basil of a susceptible cultivar exposed to naturally occurring wind-dispersed sporangiospores of P. belbahrii to evaluate conventional fungicides registered for basil downy mildew in the United States and in development for this use. This project revealed the importance for successful management of using a preventive fungicide application schedule, maintaining a 7-day application interval, and using application equipment designed to provide thorough spray coverage to plants (drop nozzles). Fungicide efficacy was assessed based on incidence of symptomatic leaves rather than disease severity, which is stringent but realistic because there is zero tolerance for disease on fresh-market herbs. Most fungicides were tested as the formulated product marketed in the United States. Oxathiapiprolin was tested as experimental formulations. Its trade name is Orondis. Overall best control was achieved in 2016. Excellent control (99% based on AUDPC values) was obtained with four fungicide programs with oxathiapiprolin, Revus, and ProPhyt, indicating this combination of chemistry was more important than specific timing for each fungicide. Ranman applied in alternation with Revus plus K-Phite was not quite as effective (89% control); this treatment was ineffective in 2015 when the 7-day spray interval was not maintained. Best treatment in 2015 was Quadris applied in alternation with Revus plus oxathiapiprolin for two of three Revus applications. Two different alternations of these fungicides also were effective. But Quadris alternated with Revus was ineffective. When tested singly, the most effective fungicides in 2013 (listed in order based on AUDPC values) were Zampro, Revus, oxathiapiprolin, and Ranman. ProPhyt was effective in 2013 but not in 2012, when another phosphorous acid fungicide, K-Phite, also was ineffective. Only oxathiapiprolin and Zampro were effective in the 2012 experiment; Revus and Ranman were ineffective. Presidio was ineffective both years. Based on the results from this study, Orondis is the most effective fungicide among those evaluated for managing basil downy mildew, and Zampro is second. Neither were labeled for this use on field-grown basil as of June 2020. Ranman applied in alternation with Revus plus K-Phite, a commonly recommended program of labeled fungicides, provided very good control.

How is sexuality after stroke experienced by stroke survivors and partners of stroke survivors? A systematic review of qualitative studies.

OBJECTIVE:: To synthesise how post-stroke sexuality is experienced by stroke survivors and partners of stroke survivors. METHODS:: MEDLINE, PubMed, SCOPUS, CINAHL and PsycINFO were searched from inception to May 2018 using a combination of relevant Medical Subject Headings and Free Text Terms. Only papers published in English reporting original qualitative research were included. Methodological quality was assessed using the Critical Appraisal Skills Programme Qualitative Research Checklist. All text presented as 'results' or 'findings' in the included studies was extracted and subjected to a thematic analysis and synthesis which was discussed and agreed by the research team. RESULTS:: The initial search yielded 136 unique papers with a further 8 papers identified through reference checking. Following full-text review, 43 papers were included in the final synthesis. Two analytical themes were identified: sexuality is silenced and sexuality is muted and sometimes changed, but not forgotten. These themes were made up of six descriptive themes: struggle to communicate within relationships, health professionals don't talk about sexuality, sexuality and disability is a taboo topic, changes to pre-stroke relationships, changed relationship with the stroke survivor's own body and resuming sexual intimacy - adaptation and loss. CONCLUSION:: Stroke has a profound impact on how sexuality is experienced by both stroke survivors and partners of stroke survivors. Despite this, post-stroke sexuality is rarely discussed openly. Stroke survivors and partners value sexuality and may benefit from strategies to support adjustment to post-stroke sexuality.
