The environmental impact of nitrous oxide inhalation sedation appointments and equipment used in dentistry. Eur Arch Paediatr Dent 2024:10.1007/s40368-024-00895-6. [PMID: 38679632 DOI: 10.1007/s40368-024-00895-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 03/19/2024] [Indexed: 05/01/2024]
Abstract
PURPOSE This paper reports a life cycle impact assessment (LCIA) to calculate the environmental footprint of a dental appointment using N2O, comparing single-use equipment with reusable equipment. Nitrous oxide (N2O) is used successfully in dentistry to provide sedation and pain relief to anxious patients, most commonly in children. However, N2O is a powerful climate pollutant 298 times more damaging than carbon dioxide over a 100-year estimate. METHODS The functional unit chosen for this LCIA was 30 min delivery of N2O to oxygen in a 50:50 ratio at 6 L per minute flow rate as inhalation sedation to one patient. Two types of equipment were compared to deliver the anaesthetic gas: reusable and disposable items. RESULTS The use of disposable equipment for N2O sedation produces a significantly larger environmental impact across nearly all of the environmental impact scores, but the overall global warming potential is comparable for both types of equipment due to the vast environmental pollution from N2O itself. CONCLUSION N2O sedation is a reliable treatment adjunct but contributes to climate change. Single-use equipment has a further deleterious effect on the environment, though this is small compared to the overall impact of N2O. Dental priorities should be to deliver safe and effective care to patients that protects staff, minimises waste and mitigates impact on the environment alongside promoting research into alternatives.

Household income and health-related quality of life in children receiving treatment for acute myeloid leukemia: Potential impact of selection bias in health equity research. Cancer Med 2024; 13:e6966. [PMID: 38572962 PMCID: PMC10993703 DOI: 10.1002/cam4.6966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 12/28/2023] [Accepted: 01/15/2024] [Indexed: 04/05/2024] Open
Abstract
OBJECTIVE Examine the influence of household income on health-related quality of life (HRQOL) among children with newly diagnosed acute myeloid leukemia (AML). DESIGN Secondary analysis of data prospectively collected from pediatric patients receiving treatment for AML at 14 hospitals across the United States. EXPOSURE Household income was self-reported on a demographic survey. The examined mediators included the acuity of presentation and treatment toxicity. OUTCOME Caregiver proxy reported assessment of patient HRQOL from the Peds QL 4.0 survey. RESULT Children with AML (n = 131) and caregivers were prospectively enrolled to complete PedsQL assessments. HRQOL scores were better for patients in the lowest versus highest income category (mean ± SD: 76.0 ± 14 household income <$25,000 vs. 59.9 ± 17 income ≥$75,000; adjusted mean difference: 11.2, 95% CI: 2.2-20.2). Seven percent of enrolled patients presented with high acuity (ICU-level care in the first 72 h), and 16% had high toxicity (any ICU-level care); there were no identifiable differences by income, refuting mediating roles in the association between income and HRQOL. Enrolled patients were less likely to be Black/African American (9.9% vs. 22.2%), more likely to be privately insured (50.4% vs. 40.7%), and more likely to have been treated on a clinical trial (26.7% vs. 18.5%) compared to eligible unenrolled patients not enrolled. Evaluations of potential selection bias on the association between income and HRQOL suggested differences in HRQOL may be smaller than observed or even in the opposing direction. CONCLUSIONS While primary analyses suggested lower household income was associated with superior HRQOL, differential participation may have biased these results. Future studies should partner with patients/families to identify strategies for equitable participation in clinical research.

Efficacy of prophylactic use of intraoperative vancomycin powder in preventing surgical site infection in neurological surgeries in Irrua, Nigeria: A randomized controlled study. J Clin Neurosci 2024; 121:155-160. [PMID: 38401293 DOI: 10.1016/j.jocn.2024.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 02/02/2024] [Accepted: 02/09/2024] [Indexed: 02/26/2024]
Abstract
PURPOSE The objective was to determine the efficacy of intraoperative vancomycin powder in preventing SSIs in neurological surgeries. METHODS A prospective randomized controlled study of patients who had clean cranial and non-implant spine surgeries at the Irrua Specialist Teaching Hospital, Irrua, Nigeria from February 1, 2021 to January 31, 2022. Patients were randomized into two groups. Group A patients had prophylactic intraoperative vancomycin powder applied to the surgical bed before wound closure while group B patients did not. Patients in both groups were followed up for 30 days post-operatively for evidence of SSI. The occurrence of SSIs was determined using clinical and laboratory parameters. Baseline characteristics, operative details, rates of wound infection, and microbiological data for each case were recorded. Data was analyzed using Statistical Package for Scientific Solution (SPSS) version 23 software. RESULTS Forty-two patients were randomized into 2 groups of 21 patients each. The age range of the patients was 20 to 80 years. The majority of the patients were males (32 out of 42). The mean age of patients in group A was 48.05 ± 17.03 years, while group B had a mean age of 45.95 ± 19.14 years. The mean Body Mass Index of patients in groups A and B were 23.92 ± 5.21 and 23.21 ± 3.99 respectively. Seven out of 21 patients (33.3 %) in the control group ( group B) had superficial SSIs while no patient in the experimental group had SSI, p-value < 0.05. The organisms cultured were Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. CONCLUSION Intraoperative vancomycin powder was effective in reducing the rate of SSIs following neurological surgeries and without adverse drug reactions.

Abstract
INTRODUCTION Engaging with patients when designing a clinical or research project is beneficial; feedback from the intended audience provides invaluable insight form the patients' perspective. Working with patients can result in developing successful research grants and interventions. The benefit of including the voice of the patient in the Yorkshire Cancer Research funded PREHABS study is described in this article. METHODS Patients were included in the PREHABS study from inception to completion. The Theory of Change methodology was used to provide a framework to implement patient feedback to refine the study intervention. RESULTS In total, 69 patients engaged with the PREHABS project. Two patients were recruited as co-applicants on the grant and were members on the Trial Management Group. Six patients attended the pre application workshop and provided feedback on their lived experiences of being a lung cancer patient. Commentary from the patients influenced the interventions selected and the design of the prehabs study. Following ethical approval (21/EE/0048) and informed written consent, 61 patients were recruited into the PREHABS study between October 2021 and November 2022. The breakdown of recruited patients was 19 males: mean age 69.1 years (SD 8.91) and 41 females; mean age 74.9 years (SD 8.9). CONCLUSION It is practicable and beneficial to include patients at all stages of designing and delivering a research study. Patient feedback can help refine the study interventions to allow for maximum acceptance, recruitment and retention. IMPLICATIONS FOR PRACTICE Including patients in the design of radiotherapy research studies can provide invaluable insight that can support the selection and delivery of interventions that are acceptable to the patient cohort.

Abstract
OBJECTIVES Protestant Christians are more likely to own firearms and not store them locked/unloaded compared to those from other religions. This study examines how Protestant Christians view the relationship between their religious and firearm beliefs and how that informs openness to church-based firearm safety interventions. STUDY DESIGN Grounded theory analysis of 17 semi-structured interviews with Protestant Christians. METHODS Interviews, conducted August-October 2020, focused on firearms owned, carrying/discharge/storage behaviors, Christian belief compatibility with firearm ownership, and openness to church-based firearm safety interventions. Audio-recorded interviews were transcribed verbatim and analyzed using grounded theory techniques. RESULTS Participant perspectives varied on firearm ownership motivations and compatibility of Christian values with firearm ownership. Variation in these themes and in openness to church-based firearm safety interventions resulted in clustering of participants into three groups. Group 1 owned firearms for collecting/sporting purposes and intricately connected their Christian identity with firearm ownership, but they were not open to intervention due to perceived high firearm proficiency. Group 2 did not connect their Christian identity to their firearm ownership; some believed these identities were incompatible, so were also not open to intervention. Group 3 owned firearms for protection and believed church, as a community hub, was an excellent location for firearm safety interventions. CONCLUSIONS The clustering of participants into groups varying in openness to church-based firearm safety interventions suggests it is feasible to identify Protestant Christian firearm owners open to intervention. This study presents a first step in coupling firearm owner characteristics with community-based, tailored interventions with promise for efficacy.

Abstract
BACKGROUND Bloodstream infections (BSIs) are a frequent cause of morbidity in patients with acute myeloid leukemia (AML), due in part to the presence of central venous access devices (CVADs) required to deliver therapy. OBJECTIVE To determine the differential risk of bacterial BSI during neutropenia by CVAD type in pediatric patients with AML. METHODS We performed a secondary analysis in a cohort of 560 pediatric patients (1,828 chemotherapy courses) receiving frontline AML chemotherapy at 17 US centers. The exposure was CVAD type at course start: tunneled externalized catheter (TEC), peripherally inserted central catheter (PICC), or totally implanted catheter (TIC). The primary outcome was course-specific incident bacterial BSI; secondary outcomes included mucosal barrier injury (MBI)-BSI and non-MBI BSI. Poisson regression was used to compute adjusted rate ratios comparing BSI occurrence during neutropenia by line type, controlling for demographic, clinical, and hospital-level characteristics. RESULTS The rate of BSI did not differ by CVAD type: 11 BSIs per 1,000 neutropenic days for TECs, 13.7 for PICCs, and 10.7 for TICs. After adjustment, there was no statistically significant association between CVAD type and BSI: PICC incident rate ratio [IRR] = 1.00 (95% confidence interval [CI], 0.75-1.32) and TIC IRR = 0.83 (95% CI, 0.49-1.41) compared to TEC. When MBI and non-MBI were examined separately, results were similar. CONCLUSIONS In this large, multicenter cohort of pediatric AML patients, we found no difference in the rate of BSI during neutropenia by CVAD type. This may be due to a risk-profile for BSI that is unique to AML patients.

Abstract
Lung cancer is the third most common type of cancer in the UK, with nearly 50 000 new cases diagnosed a year. Treatments for lung cancer have improved in recent years with the advent of new surgical and radiotherapy techniques and the increased use of immunotherapies. These advances have resulted in increasing numbers of patients surviving beyond the completion of their treatment. Lung cancer patients are now not dying from their cancer diagnosis, but from other co-existing pathologies. Lung cancer patients commonly present with multiple comorbidities. Mitigating the effects of poor lifestyles and changing behaviours may improve the efficacy of treatments, reduce side-effects and improve the quality of life for lung cancer patients. Published evidence supports the use of interventions to manage behavioural habits, to optimise the health of patients. There is no consensus as to what, when or how to embed these into the patient pathway. Supporting patients before, during and after their cancer treatments to increase activity, eat well and stop smoking have been seen to decrease side-effects and improve patient outcomes and wellbeing. The challenge is to provide a package of interventions that is acceptable to patients and fits within the patient pathway so as not to conflict with diagnostic and therapeutic activities. This article reviews where we are today with providing behavioural support to optimise the health of lung cancer patients undergoing treatment.

Abstract
IMPORTANCE Pediatric acute myeloid leukemia (AML) requires multiple courses of intensive chemotherapy that result in neutropenia, with significant risk for infectious complications. Supportive care guidelines recommend hospitalization until neutrophil recovery. However, there are little data to support inpatient over outpatient management. OBJECTIVE To evaluate outpatient vs inpatient neutropenia management for pediatric AML. DESIGN, SETTING, AND PARTICIPANTS This cohort study used qualitative and quantitative methods to compare medical outcomes, patient health-related quality of life (HRQOL), and patient and family perceptions between outpatient and inpatient neutropenia management. The study included patients from 17 US pediatric hospitals with frontline chemotherapy start dates ranging from January 2011 to July 2019, although the specific date ranges differed for the individual analyses by design and relative timing. Data were analyzed from August 2019 to February 2020. EXPOSURES Discharge to outpatient vs inpatient neutropenia management. MAIN OUTCOMES AND MEASURES The primary outcomes of interest were course-specific bacteremia incidence, times to next course, and patient HRQOL. Course-specific mortality was a secondary medical outcome. RESULTS Primary quantitative analyses included 554 patients (272 [49.1%] girls and 282 [50.9%] boys; mean [SD] age, 8.2 [6.1] years). Bacteremia incidence was not significantly different during outpatient vs inpatient management (67 courses [23.8%] vs 265 courses [29.0%]; adjusted rate ratio, 0.73; 95% CI, 0.56 to 1.06; P = .08). Outpatient management was not associated with delays to the next course compared with inpatient management (mean [SD] 30.7 [12.2] days vs 32.8 [9.7] days; adjusted mean difference, -2.2; 95% CI, -4.1 to -0.2, P = .03). Mortality during intensification II was higher for patients who received outpatient management compared with those who received inpatient management (3 patients [5.4%] vs 1 patient [0.5%]; P = .03), but comparable with inpatient management at other courses (eg, 0 patients vs 5 patients [1.3%] during induction I; P = .59). Among 97 patients evaluated for HRQOL, outcomes did not differ between outpatient and inpatient management (mean [SD] Pediatric Quality of Life Inventory total score, 70.1 [18.9] vs 68.7 [19.4]; adjusted mean difference, -2.8; 95% CI, -11.2 to 5.6). A total of 86 respondents (20 [23.3%] in outpatient management, 66 [76.7%] in inpatient management) completed qualitative interviews. Independent of management strategy received, 74 respondents (86.0%) expressed satisfaction with their experience. Concerns for hospital-associated infections among caregivers (6 of 7 caregiver respondents [85.7%] who were dissatisfied with inpatient management) and family separation (2 of 2 patient respondents [100%] who were dissatisfied with inpatient management) drove dissatisfaction with inpatient management. Stress of caring for a neutropenic child at home (3 of 3 respondents [100%] who were dissatisfied with outpatient management) drove dissatisfaction with outpatient management. CONCLUSIONS AND RELEVANCE This cohort study found that outpatient neutropenia management was not associated with higher bacteremia incidence, treatment delays, or worse HRQOL compared with inpatient neutropenia management among pediatric patients with AML. While outpatient management may be safe for many patients, course-specific mortality differences suggest that outpatient management in intensification II should be approached with caution. Patient and family experiences varied, suggesting that outpatient management may be preferred by some but may not be feasible for all families. Further studies to refine and standardize safe outpatient management practices are warranted.

Abstract
Background Suboptimal adherence to 6-mercaptopurine (6-MP) is prevalent in pediatric acute lymphoblastic leukemia (ALL) and associated with increased risk of relapse. Rapid uptake of personal technology makes mobile health (mHealth) an attractive platform to promote adherence. Objective Study objectives were to examine access to mobile technology and preferences for an mHealth intervention to improve medication adherence in pediatric ALL. Methods A cross-sectional survey was administered in oncology clinic to parents of children with ALL as well as adolescents and young adults (AYAs) with ALL receiving maintenance chemotherapy. Results A total of 49 parents (median age [IQR] 39 [33-42] years; female 76% [37/49]) and 15 patients (median age [IQR] 17 [16-19]; male 80% [12/15]) participated. All parents and AYAs owned electronic tablets, smartphones, or both. Parents’ most endorsed mHealth app features included a list of medications (71%, 35/49), information about 6-MP (71%, 35/49), refill reminders (71%, 35/49), and reminders to take 6-MP (71%, 35/49). AYAs' most endorsed features included refill reminders (73%, 11/15), reminders to take 6-MP (73%, 11/15), and tracking 6-MP (73%, 11/15). Conclusions Parents and AYAs reported ubiquitous access to mobile technology and strong interest in multiple adherence-specific mHealth app features. Parents and AYAs provided valuable insight into preferred features for a multifunctional behavioral intervention (mHealth app) to promote medication adherence in pediatric ALL.

Abstract
BACKGROUND Adherence to oral chemotherapy, including 6-mercaptopurine (6-MP), is suboptimal in pediatric acute lymphoblastic leukemia (ALL), which is associated with increased risk of relapse. Study objectives were to examine self-reported adherence to 6-MP and related barriers to adherence, mapped to the capability, opportunity, motivation, and behavior (COM-B) model for behavior change. PROCEDURE Forty-nine parents (median, 39 years old; 76% females) and 15 patients (median, 17 years old, 20% females) completed the study survey. RESULTS Suboptimal adherence was reported in 43% of parents and 73% of patients. Most parents and patients (80% and 90%, respectively) reported ≥1 adherence barrier. Parents reported difficulty helping their child meet others with ALL (43%), contacting community organizations (39%), and meeting other parents (37%). Patients reported difficulty finding out what their medications are (40%), finding out what 6-MP does (47%), and meeting other patients (40%). Using the COM-B, we found that parents and patients endorsed barriers in multiple components, especially physical (55%, 67%) and social opportunity (56%, 47%), highlighting that barriers to adherence may be multifaceted. CONCLUSIONS Our results suggest that parents and patients with ALL face various prevalent barriers to medication adherence and provide insight into the development of behavioral interventions focused on promoting adherence, which is essential to prevent relapse and optimize health outcomes in ALL.

Abstract
Neurosurgical services is an essential component of tertiary level of health care, this field is still evolving in Nigeria with lack of material and manpower. There is a near complete absence of neurosurgeons in the rural communities in Nigeria with over 95% resident in urban area. Starting a neurosurgical services takes a huge sacrifice from the neurosurgeon who is faced with a decision to do something in the presence of a near absence of material and manpower, and in turn circumvent processes with extra burden so as to ensure he/she provides leadership with respect to patients care and assists in the training of allied surgeons and other healthcare staffs to mitigate against morbidity and mortality. Our research is aimed to highlight the total number of patients attended to in the neurosurgical unit, challenges, prospect, and future.

Abstract
First described in a publication by two Nigerian Neurosurgeons, Adeloye A and Odeku EL, in 1971, Adeloye-Odeku disease is a solitary congenital subgaleal inclusion dermoid cyst of the anterior fontanelle. This rare lesion, which makes up about 0.1-0.5% of all cranial tumours and 0.2% of all inclusion cysts, was initially thought to be found only in Africans. However, further reports have shown it to have a universal occurrence, as it has been reported in Caucasians, Chinese, Indians, and other part of the world. This lesion is also known as Congenital inclusion dermoid cyst (CIDS), is a benign slow-growing lesion, and if untreated, may persist to adult life.
This article gives a highlight of the disease and its management and goes further to report 3 cases of this rare benign lesion seen in Irrua, South-South Nigeria, a rural, low-resource tertiary health institution.
Incidentally and interestingly, all three cases presented within three consecutive months (January-March, 2019) at the neurosurgery outpatient clinic. Being uncomplicated cases, private and group counselling was done. The parents of the patients were much more reassured and relieved from their anxieties seeing others with similar problem. They were all worked up for surgery at different dates, had excision of the cysts with no complication and are currently being followed at the outpatient clinic.

Analysis of pooled genome sequences from Djallonke and Sahelian sheep of Ghana reveals co-localisation of regions of reduced heterozygosity with candidate genes for disease resistance and adaptation to a tropical environment. BMC Genomics 2019; 20:816. [PMID: 31699027 PMCID: PMC6836352 DOI: 10.1186/s12864-019-6198-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Accepted: 10/16/2019] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND The Djallonke sheep is well adapted to harsh environmental conditions, and is relatively resistant to Haemonchosis and resilient to animal trypanosomiasis. The larger Sahelian sheep, which cohabit the same region, is less well adapted to these disease challenges. Haemonchosis and Trypanosomiasis collectively cost the worldwide animal industry billions of dollars in production losses annually. RESULTS Here, we separately sequenced and then pooled according to breed the genomes from five unrelated individuals from each of the Djallonke and Sahelian sheep breeds (sourced from Ghana), at greater than 22-fold combined coverage for each breed. A total of approximately 404 million (97%) and 343 million (97%) sequence reads from the Djallonke and Sahelian breeds respectively, were successfully mapped to the sheep reference genome Oar v3.1. We identified approximately 11.1 million and 10.9 million single nucleotide polymorphisms (SNPs) in the Djallonke and Sahelian breeds, with approximately 15 and 16% respectively of these not previously reported in sheep. Multiple regions of reduced heterozygosity were also found; 70 co-localised within genomic regions harbouring genes that mediate disease resistance, immune response and adaptation in sheep or cattle. Thirty- three of the regions of reduced heterozygosity co-localised with previously reported genes for resistance to haemonchosis and trypanosomiasis. CONCLUSIONS Our analyses suggest that these regions of reduced heterozygosity may be signatures of selection for these economically important diseases.

Abstract
Abstract
Background
Endoscopic third ventriculostomy (ETV) is becoming a popular option of treatment in carefully selected patients with hydrocephalus (Drake et al., Childs Nerv Syst 25:467-472, 2009). The success or possible outcome of its application in treating hydrocephalus can be predicted by employing a preoperative scoring system. An example of such a system is the endoscopic third ventriculostomy success score (ETVSS). It could form a basis for decision-making and prognostication. This study aimed to evaluate ETVSS as a preoperative predictive tool in children with hydrocephalus who satisfy the inclusion criteria for the option of ETV procedure as treatment modality.
Methodology
This is a prospective hospital-based study of 68 children under 2 years of age that presented at the Lagos University Teaching Hospital (LUTH) out of 161 children with hydrocephalus from November 2014 to April 2016. The predicted ETVSS was calculated by the addition of patients’ age, presumed aetiology and prior shunting. These children were stratified into three groups according to ETVSS as higher score predicts better ETV outcome and vice versa. They were followed up for 6 months to determine the success rate of ETV.
Results
The age of the study population ranged from 0 to 24 months with a mean age of 5.52 ± 5.48 months. 69.1% of these patients were male and 30.9% were female with a male to female ratio of 2.2:1. The mean predicted ETVSS (48.82 ± 19.20%) and actual ETV success score (56.20 ± 15.10%) using the ANOVA were significantly related (p value < 0.05).
Conclusion
This study concluded that the early outcome of ETV in children below 2 years of age with hydrocephalus is directly related to the preoperative ETVSS.

Abstract
BACKGROUND Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), together known as keratinocyte cancers (KCs), are the commonest cancer in white ethnic populations. Recent improvements to registry data collection in England has allowed more accurate analysis of the epidemiology of BCC and cSCC and for the first time we are able to provide an accurate (representative) tumour burden for KC in the U.K. OBJECTIVES To estimate the incidence of BCC and cSCC in the U.K. METHODS A cohort of patients with KCs between 2013 and 2015 were identified using linkage to diagnostic codes derived from pathology reports collected into the national cancer registry. Data from England's cancer registry were combined with data from Scotland, Northern Ireland and Wales. European age-standardized incidence rates (EASRs) of the first BCC and cSCC per patient per annum (PPPA) were calculated. RESULTS In the U.K, the EASR of the first BCC and cSCC PPPA in 2013-15 were 285 and 77 per 100 000 person years, respectively (211 120 KCs total in 2015). The mean annual percentage increase was 5% between 2013 and 2015 for both BCC and cSCC. By counting the first KC PPPA, we include an additional 51% KCs compared with the previous reporting technique which counts only the first BCC and cSCC in a patient's lifetime, yet it represents a probable underestimation of 5-11% of the true tumour count. CONCLUSIONS Based on an improved methodology, a more representative incidence of KC is presented, which is essential to healthcare planning and will lead to improved understanding of the epidemiology of KC. What's already known about this topic? Keratinocyte cancers (KCs) are the most common cancers affecting white ethnic populations. The incidence of basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) is increasing worldwide including the U.K., most commonly in elderly male Caucasian patients. These cancers are traditionally substantially underreported and frequently excluded from national cancer statistics. What does this study add? Using improved data collection methods in England and validated tumour-reporting techniques, we report the most accurate BCC and cSCC incidence data for the U.K. ever published. Identifying the first BCC and cSCC per patient per annum, the incidence of BCC and cSCC in the U.K. (excluding Wales) was 285 and 77 per 100 000 person years, respectively, between 2013 and 2015, with more than 210 000 KCs in the U.K. in 2015.

Abstract
Meningiomas are relatively common primary spinal tumours, being the second most common intraspinal tumours probably after vertebral haemangioma.It constitutes about 25% of all intraspinal tumours; however, in the presence of extradural spinal lesions, the diagnosis of meningioma is uncommon and often not among the first two considerations. Purely extradural spinal meningioma, especially of the “En plaque” variety, usually simulate malignant disease (metastatic diseases and lymphoma) and may result in inadequate therapy, however, the presence of nerve root attachment is even rarer.Our case report is that of an entirely cervicothoracic extradural en?plaque meningioma (WHO grade 1) with a nerve root attachment (right C7) and intrathoracic extension. We highlighted the issues in diagnosis, operative intervention and long-term follow-up.

Experiences of Stigma and Support Reported by Participants in a Network Intervention to Reduce HIV Transmission in Athens, Greece; Odessa, Ukraine; and Chicago, Illinois. AIDS Behav 2019; 23:1210-1224.

Abstract
A growing body of evidence suggests that network-based interventions to reduce HIV transmission and/or improve HIV-related health outcomes have an important place in public health efforts to move towards 90-90-90 goals. However, the social processes involved in network-based recruitment may pose a risk to participants of increasing HIV-related stigma if network recruitment causes HIV status to be assumed, inferred, or disclosed. On the other hand, the social processes involved in network-based recruitment to HIV testing may also encourage HIV-related social support. Yet despite the relevance of these processes to both network-based interventions and to other more common interventions (e.g., partner services), there is a dearth of literature that directly examines them among participants of such interventions. Furthermore, both HIV-related stigma and social support may influence participants' willingness and ability to recruit their network members to the study. This paper examines (1) the extent to which stigma and support were experienced by participants in the Transmission Reduction Intervention Project (TRIP), a risk network-tracing intervention aimed at locating recently HIV-infected and/or undiagnosed HIV-infected people and linking them to care in Athens, Greece; Odessa, Ukraine; and Chicago, Illinois; and (2) whether stigma and support predicted participant engagement in the intervention. Overall, experiences of stigma were infrequent and experiences of support frequent, with significant variation between study sites. Experiences and perceptions of HIV-related stigma did not change significantly between baseline and six-month follow-up for the full TRIP sample, and significantly decreased during the course of the study at the Chicago site. Experiences of HIV-related support significantly increased among recently-HIV-infected participants at all sites, and among all participants at the Odessa site. Both stigma and support were found to predict participants' recruitment of network members to the study at the Athens site, and to predict participants' interviewer-rated enthusiasm for naming and recruiting their network members at both the Athens and Odessa sites. These findings suggest that network-based interventions like TRIP which aim to reduce HIV transmission likely do not increase stigma-related risks to participants, and may even encourage increased social support among network members. However, the present study is limited by its associational design and by some variation in implementation by study site. Future research should directly assess contextual differences to improve understanding of the implications of site-level variation in stigma and support for the implementation of network-based interventions, given the finding that these constructs predict participants' recruitment of network members and engagement in the intervention, and thereby could limit network-based interventions' abilities to reach those most in need of HIV testing and care.

Abstract
There are no consensus guidelines for management of pediatric oncology patients presenting with fever and nonneutropenia, with limited research into the outcomes of withholding empiric i.v. antibiotics. We conducted a prospective cohort study assessing the safety and efficacy of observing well-appearing patients presenting with fever and nonneutropenia (absolute neutrophil count ≥ 500 cells/mm3 ). Of 238 episodes, 82.7% patients were observed with no infectious complications and low overall incidence of bacteremia (3.4%). There were no significant differences in individual clinical variables. We propose that observation alone in some well-appearing febrile pediatric oncology patients is safe and limits the use of unnecessary empiric antibiotics.

Abstract
In the present study a severe outbreak of hemorrhagic pneumonia (HP) in neonatal minks concomitant with Leismania infantum (L. infantum) detection is reported. The outbreak took place on a Greek mink farm and affected 1,362 mink kits, with 524 dying. Macroscopic lesions of 14 necropsied affected kits were confined to the respiratory system with dark red, consolidated lung lobes and to the small intestine with severe, acute, hemorrhagic and necrotic enteritis. Microscopic examination of lung sections revealed severe hemorrhagic pyogranulomatous pneumonia. Bacteria were obtained in pure culture from the lungs of all necropsied animals and were confirmed as Pseudomonas aeruginosa (P. aeruginosa). Three out of 14 (21.4%) animals were positive for the presence of L. infantum DNA. The outbreak was attributed to the infection of minks with P. aeruginosa, possibly as a consequence of being immuno-suppressed by L. infantum. Further research is necessary, especially on the pathogenesis of P. aeruginosa/L. infantum co-infection and the implications of this interaction on HP disease outcome.

Abstract
Wilms tumor (WT) treatment regimens are curative for more than 80% of patients, but those with relapsed or refractory disease continue to have poor outcomes. High-dose chemotherapy followed by autologous stem cell rescue is often utilized although outcomes remain variable. We report on HD-ASCR outcomes in 24 patients with relapsed or refractory Wilms tumor. Three-year disease free and overall survival are 46% and 60%, respectively, which is similar to those reported for conventional salvage therapies. These outcomes suggest that conventional salvage therapies should be employed for relapsed and refractory WT rather than HD-ASCR.

Abstract
BACKGROUND We analysed trends in incidence for in situ and invasive melanoma in some European countries during the period 1995-2012, stratifying for lesion thickness. MATERIAL AND METHODS Individual anonymised data from population-based European cancer registries (CRs) were collected and combined in a common database, including information on age, sex, year of diagnosis, histological type, tumour location, behaviour (invasive, in situ) and lesion thickness. Mortality data were retrieved from the publicly available World Health Organization database. RESULTS Our database covered a population of over 117 million inhabitants and included about 415,000 skin lesions, recorded by 18 European CRs (7 of them with national coverage). During the 1995-2012 period, we observed a statistically significant increase in incidence for both invasive (average annual percent change (AAPC) 4.0% men; 3.0% women) and in situ (AAPC 7.7% men; 6.2% women) cases. DISCUSSION The increase in invasive lesions seemed mainly driven by thin melanomas (AAPC 10% men; 8.3% women). The incidence of thick melanomas also increased, although more slowly in recent years. Correction for lesions of unknown thickness enhanced the differences between thin and thick cases and flattened the trends. Incidence trends varied considerably across registries, but only Netherlands presented a marked increase above the boundaries of a funnel plot that weighted estimates by their precision. Mortality from invasive melanoma has continued to increase in Norway, Iceland (but only for elder people), the Netherlands and Slovenia.

Abstract
Type III solar radio bursts are the Sun's most intense and frequent nonthermal radio emissions. They involve two critical problems in astrophysics, plasma physics, and space physics: how collective processes produce nonthermal radiation and how magnetic reconnection occurs and changes magnetic energy into kinetic energy. Here magnetic reconnection events are identified definitively in Solar Dynamics Observatory UV-EUV data, with strong upward and downward pairs of jets, current sheets, and cusp-like geometries on top of time-varying magnetic loops, and strong outflows along pairs of open magnetic field lines. Type III bursts imaged by the Murchison Widefield Array and detected by the Learmonth radiospectrograph and STEREO B spacecraft are demonstrated to be in very good temporal and spatial coincidence with specific reconnection events and with bursts of X-rays detected by the RHESSI spacecraft. The reconnection sites are low, near heights of 5-10 Mm. These images and event timings provide the long-desired direct evidence that semi-relativistic electrons energized in magnetic reconnection regions produce type III radio bursts. Not all the observed reconnection events produce X-ray events or coronal or interplanetary type III bursts; thus different special conditions exist for electrons leaving reconnection regions to produce observable radio, EUV, UV, and X-ray bursts.

Abstract
BACKGROUND Prompt central venous catheter (CVC) removal is currently recommended in children with Staphylococcus aureus central line-associated bloodstream infection (CLABSI). Our objective was to examine the outcome of attempted line salvage in children with S. aureus CLABSI and assess predictors of success. METHODS A single-institution, retrospective cohort study was performed of all children with S. aureus CLABSI between 2012 and 2015. Patients with and without immediate CVC removal (≤ 2 days after first positive culture) were compared. The primary outcome was failed CVC salvage (removal after 3+ days). RESULTS Seventy-seven children met criteria for S. aureus CLABSI. Immediate CVC removal was performed in 27.3% of patients. Among the 72.7% patients in whom CVC salvage was attempted, 78.6% were successful and 21.4% required delayed CVC removal. Malignancy, short gut syndrome, neutropenia, methicillin-resistant S. aureus, and line type were not associated with salvage failure. No associated morbidity or mortality occurred in patients with a failed salvage attempt. New or recurrent bacteremia occurred in five patients, but three were successfully salvaged a second time. CONCLUSIONS CVC salvage was feasible in the majority of children with S. aureus CLABSI and was not associated with significant complications or attributable mortality as reported in adults.

Abstract
In the last five years, options for the treatment of vulvar intraepithelial neoplasia (VIN) have come to include the use of the immune response modifier imiquimod, following case reports of its efficacy in the USA and Europe. Despite topical imiquimod 5% cream being frequently prescribed for the treatment of ano-genital warts, there are no reports of it being used for the treatment of VIN in a genitourinary medicine setting. In this case report self-administered topical imiquimod 5% cream proved an effective treatment for undifferentiated VIN2/3 and should be considered as an alternative therapy in a genitourinary medicine setting.

Abstract
Methotrexate is associated with neurologic side effects. It is recommended that patients who developed neurotoxicity be rechallenged with methotrexate, but little is known about the safety of this approach. We performed a chart review to identify patients who received high-dose or intrathecal (IT) methotrexate. Twenty-one of 298 patients (7%) experienced neurologic symptoms attributed to methotrexate treatment in the premaintenance phase. Seventeen of these patients were rechallenged with IT methotrexate and 13 (76%) had no further neurotoxic events. No patients rechallenged during maintenance (n = 9) experienced recurrence of neurotoxic events. It is safe to rechallenge with IT methotrexate in maintenance.

Abstract
BACKGROUND Outcomes for high-risk neuroblastoma remain poor. Modern treatment protocols utilizing intense induction followed by myeloablative consolidation chemotherapy with autologous stem cell rescue (ASCR) have improved survival rates, but the long-term sequelae, including development of secondary malignant neoplasms (SMN), are just now surfacing. METHODS We retrospectively reviewed data from 87 patients with high-risk neuroblastoma who were treated with intensive induction chemotherapy followed by ASCR between January 1991 and July 2011 following one of two institutional protocols: Chicago Pilot 1 (CP1; n = 12) and Chicago Pilot 2 (CP2; n = 75). RESULTS The 15-year overall survival rate for all 87 patients was 33.9% (95% confidence interval [CI], 23.1-45.0%). The 10- and 15-year cumulative incidence of SMN was 16.5% (95%CI, 7.2-38.0%) and 34.2% (95%CI, 18.6-63.1%), respectively, without evidence of a plateau at 15 years. Six of the 10 patients (n = 2 in CP1 and n = 8 in CP2) who developed SMN had hematologic malignancies including acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS). Solid tumors included thyroid papillary carcinoma, chondrosarcoma, hepatocellular carcinoma, and biliary adenocarcinoma. CONCLUSION A significantly higher incidence of SMN, especially hematological malignancies, was observed in this cohort compared to older neuroblastoma studies, potentially due to exposure to epipodophyllotoxins and a high cumulative dose of alkylating agents these patients received. The risk of developing an SMN continued to increase with survival time and did not reach the plateau at 15 years. Although the number of the patients is relatively small, our study emphasizes the need for life-long follow-up of survivors who were treated using modern therapy.

Abstract
AIMS To investigate whether young people with Type 1 diabetes have an increased rate of depression and antidepressant use and whether their risk varies by age group, time from diabetes diagnosis, calendar period of diagnosis or complications status. METHODS A cohort of incident cases of patients with Type 1 diabetes diagnosed before 35 years of age (n = 5548) was identified within the Clinical Practice Research Datalink and individually age and sex matched with up to two control subjects without diabetes (n = 10 657). Patients with depression were identified through general practice-recorded depression codes and antidepressant prescriptions. Cox regression models gave hazard ratios for depression in people with Type 1 diabetes compared with control subjects. RESULTS People with Type 1 diabetes were twice as likely to have a record of antidepressant use and general practice-diagnosed depression as their matched control subjects (hazard ratio 2.08, 95% CI 1.73-2.50, P < 0.001). These associations varied by time from diagnosis, with marked increases observed within the first 5 years of diagnosis (hazard ratio 2.14, 95% CI 1.51-3.03, P < 0.001), and by age at diabetes diagnosis, with excesses noted even in the 10- to 19-year age group (hazard ratio 1.45, 95% CI 1.06-1.98, P = 0.02). CONCLUSIONS This population-based study shows that people with Type 1 diabetes have higher rates of general practice-recorded depression and antidepressant use. The excess is present within 5 years of diabetes diagnosis, suggesting psychological input for patients is warranted in the early years of their condition.

Abstract
Relapsed acute lymphoblastic leukemia (ALL) represents a major cause of morbidity and mortality in pediatrics. With contemporary chemotherapy, >85% of patients with newly diagnosed ALL survive. Unfortunately, 20% of these patients will relapse and for these children, outcomes remain poor despite our best known chemotherapy protocols. Most of these children will achieve a second complete remission, but maintaining this remission remains difficult. Because relapsed ALL is such a significant cause of morbidity and mortality, it is the focus of much research interest. Efforts have been made and continue to focus on understanding the underlying biology that drives relapse. The role of hematopoietic stem cell transplantation in relapsed ALL remains unclear, but many clinicians still favor this for high-risk patients given the poor prognosis with current chemotherapy alone. It is important to use new drugs with little cross-resistance in the treatment of relapsed ALL. New classes of agents are currently being studied. We also discuss prognostic factors and the biology of relapsed ALL.
