Published: June 2020

Purpose: To describe a case of retinopathy as onset manifestation of chronic myeloid leukemia (CML), successfully treated with leukapheresis and medical therapy. Methods: A 28-year-old male patient presented complaining painless acute visual impairment in his right eye (RE). He reported moderate asthenia and episodes of night sweats during the previous month. His past medical history was unremarkable. BCVA at presentation was 20/80 in RE and 20/32 in left eye (LE). Fundus examination revealed venous congestion, diffuse Roth spots, and whitish macular infiltrates in both eyes. OCT showed hyperreflective foveal infiltrates, in both eyes. Blood test showed markedly elevated white blood cells (WBCs) count (430 × 103/mm3). Clinical-instrumental examination revealed hepatosplenomegaly. These features were consistent with CML. The patient was treated with leukapheresis and nilotinib. Results: After 2 weeks of treatment, the WBCs count dropped (71 × 103/mm3), and the patient reported subjective improvement of symptoms. At 1-month follow-up, BCVA and retinopathy signs were improved in both eyes. OCT showed the almost complete resolution of foveal infiltrates with ellipsoid zone focal defects. At 4-months follow-up, we observed complete resolution of retinopathy. BCVA was 20/32 in RE and 20/25 in LE. OCT showed the persistence of ellipsoid zone focal defects in RE and complete anatomical restoration in LE. At 6-months follow-up, the patient was clinically well and his WBCs count was normal. Conclusion: In our case, the CML-related retinopathy represented the onset sign of the underlying systemic pathology, leading to proper management and treatment, with hematological normalization and resolution of the retinopathy.

Background: The spinal cord (SC) is highly relevant to disability in multiple sclerosis (MS), but few studies have evaluated longitudinal changes in quantitative spinal cord magnetic resonance imaging (SC-MRI). Objectives: The aim of this study was to characterize the relationships between 5-year changes in SC-MRI with disability in MS. Methods: In total, 75 MS patients underwent 3 T SC-MRI and clinical assessment (expanded disability status scale (EDSS) and MS functional composite (MSFC)) at baseline, 2 and 5 years. SC-cross-sectional area (CSA) and diffusion-tensor indices (fractional anisotropy (FA), mean, perpendicular, parallel diffusivity (MD, λ⊥, λ||) and magnetization transfer ratio (MTR)) were extracted at C3–C4. Mixed-effects regression incorporating subject-specific slopes assessed longitudinal change in SC-MRI measures. Results: SC-CSA and MTR decreased ( p = 0.009, p = 0.03) over 5.1 years. There were moderate correlations between 2- and 5-year subject-specific slopes of SC-MRI indices and follow-up EDSS scores (Pearson’s r with FA = −0.23 ( p < 0.001); MD = 0.31 ( p < 0.001); λ⊥ = 0.34 ( p < 0.001); λ|| = −0.12 ( p = 0.05), MTR = −0.37 ( p < 0.001); SC-CSA = −0.47 ( p < 0.001) at 5 years); MSFC showed similar trends. The 2- and 5-year subject-specific slopes were robustly correlated ( r = 0.93–0.97 for FA, λ⊥, SC-CSA and MTR, all ps < 0.001). Conclusion: In MS, certain quantitative SC-MRI indices change over 5 years, reflecting ongoing tissue changes. Subject-specific trajectories of SC-MRI index change at 2 and 5 years are strongly correlated and highly relevant to follow-up disability. These findings suggest that individual dynamics of change should be accounted for when interpreting longitudinal SC-MRI measures and that measuring short-term change is predictive of long-term clinical disability.
Dropping out and moving on: A qualitative study of autistic people’s experiences of university
Authors: Cage Eilidh , Howes Jack 
Published: June 2020

Autistic people are at high risk of dropping out of university, but little research has examined this issue. Fourteen autistic people participated in semi-structured interviews examining their experiences at university and the reasons they had dropped out. Thematic analysis identified patterns in participants’ responses. Themes were categorised as systemic issues, challenges within university or life after dropping out. Systemic issues centred around accessing diagnosis, autism understanding, mental health and outsider status. Challenges at university included culture shock, becoming disengaged, lack of proactive support and perceived inevitability of dropping out. Finally, life after dropping out was characterised by processing of trauma and shame, and realisation of doing ‘what’s right for you’. Together, these themes suggest that many improvements could be made at universities, such as more proactive support and creating more accessible environments. Societal-level change is also needed to improve educational opportunities for autistic people. Lay abstract Many autistic people now go to university, but many of them also drop out of their studies. In fact, it is believed that autistic people are at higher risk of dropping out, but little research has been done to understand why this is happening. This research used interviews to take an in-depth look at 14 autistic people’s experiences of dropping out of university. All the things the participants talked about were examined closely by the researchers who identified common themes in what the participants discussed. The first set of themes captured some overarching issues faced by autistic people, such as difficulties with getting diagnosed, a lack of autism understanding, mental health challenges and feeling like an outsider. The next themes were organised within challenges faced at university, including a feeling of culture shock, becoming disengaged from one’s studies, a lack of proactive support from their university and a feeling that dropping out became inevitable. Finally, there were themes about life after dropping out, which involved a sense that the experience at university had been traumatic and shameful, but they believed people had to do what is right for them. All of these themes suggest that universities need to be better at supporting autistic people when they first come to university, and that they should actively offer clear support throughout and try and make the university environment more accessible for everyone, to ensure more autistic people have a positive university experience.
Head circumference trends in autism between 0 and 100 months

Published: June 2020

Meta-analyses of head circumference in autistic individuals exist; however, simple meta-analytic approaches are limited. Consequently, we gathered head circumference raw data of autistic ( N = 2381) and typically developing participants ( N = 994) by re-analysing the data from previously published studies together. The present study found no mean difference between head circumference of autistic and typically developing individuals, although simple effect analyses revealed smaller mean head circumference in autistic than typically developing females aged 12–17 months. However, compared to controls, the frequency of extreme head circumference in autistic males was greater at birth and between 60 and 100 months. In addition, the frequency of extremely small head circumference between 6 and 11 months, and extremely large head circumference between 12 and 17 months, was greater in autistic than typically developing males. For autistic females, compared to controls, extreme head circumference was more frequent between 36 and 59 months and less frequent at birth. We conclude that it is imperative to consider the effects of age and sex when investigating the relationship between autism diagnosis and head circumference. This variance was more effectively described via the approach of the present study than previous meta-analytic approaches. Lay abstract Summaries of studies that have measured head size in those with autism, known as meta-analyses, currently exist. However, this approach does not adequately explain extreme cases (such as those with extremely small, or extremely large, head size). Because of this, we obtained all available published data measuring head size (12 studies). The data from each study were then combined to make a larger dataset. We found that females with autism aged 12–17 months had, on average, smaller head sizes. Otherwise, average head size was not atypical in autism. However, we found that males with autism were more likely to have extreme head sizes at birth and between 60 and 100 months, a small head between 6 and 11 months, and a large head between 12 and 17 months. Females with autism were more likely to have extreme head sizes between 36 and 59 months and were less likely at birth. Our approach was able to measure the influence of age and biological sex on head size in autism, as well as the frequency of extreme cases of head size in autism. These results add to what we already know about head size in autism.

Authors: Wagner Eric R. , Barras Laurel A. , Fort Michael W. , Robinson William , Rizzo Marco 
Published: June 2020

This investigation assessed 106 consecutive primary proximal interphalangeal joint arthroplasties performed on border digits: 73 index or 33 little fingers. This was compared with 193 arthroplasties performed in non-border digits: 121 middle or 72 ring fingers. There were 20 proximal interphalangeal joint arthroplasties in the border digits that required revision surgery for pain and stiffness (10 digits), dislocation (six digits), implant fracture (one digit), and infection (three digits). Risk of revision surgery was not associated with border digit. The 5-year implant survival rate for the border digits was 81%. There was no significant difference in implant revision rate or joint dislocations between border and non-border digits. We conclude that proximal interphalangeal joint arthroplasties performed in border digits had similar pain relief, survivorship, complications, and reoperation rates compared with those performed in non-border digits. Level of evidence: IV

Published: June 2020

Background: Hypoglycemia is a serious health concern in youth with type 1 diabetes (T1D). Real-time data from continuous glucose monitoring (CGM) can be used to predict hypoglycemic risk, allowing patients to take timely intervention measures. Methods: A machine learning model is developed for probabilistic prediction of hypoglycemia (<70 mg/dL) in 30- and 60-minute time horizons based on CGM datasets obtained from 112 patients over a range of 90 days consisting of over 1.6 million CGM values under normal living conditions. A comprehensive set of features relevant for hypoglycemia are developed and a parsimonious subset with most influence on predicting hypoglycemic risk is identified. Model performance is evaluated both with and without contextual information on insulin and carbohydrate intake. Results: The model predicted hypoglycemia with >91% sensitivity for 30- and 60-minute prediction horizons while maintaining specificity >90%. Inclusion of insulin and carbohydrate data yielded performance improvement for 60-minute but not for 30-minute predictions. Model performance was highest for nocturnal hypoglycemia (~95% sensitivity). Shortterm (less than one hour) and medium-term (one to four hours) features for good prediction performance are identified. Conclusions: Innovative feature identification facilitated high performance for hypoglycemia risk prediction in pediatric youth with T1D. Timely alerts of impending hypoglycemia may enable proactive measures to avoid severe hypoglycemia and achieve optimal glycemic control. The model will be deployed on a patient-facing smartphone application in an upcoming pilot study.

Abstract

Aims
Remodelling of the cardiovascular system (including heart and vasculature) is a dynamic process influenced by multiple physiological and pathological factors. We sought to understand whether remodelling in response to a stimulus, exercise training, altered with healthy ageing.

Methods
A total of 237 untrained healthy male and female subjects volunteering for their first time marathon were recruited. At baseline and after 6 months of unsupervised training, race completers underwent tests including 1.5T cardiac magnetic resonance, brachial and non-invasive central blood pressure assessment. For analysis, runners were divided by age into under or over 35 years (U35, O35).

Results
Injury and completion rates were similar among the groups; 138 runners (U35: n = 71, women 49%; O35: n = 67, women 51%) completed the race. On average, U35 were faster by 37 minutes (12%). Training induced a small increase in left ventricular mass in both groups (3 g/m2, P &lt; 0.001), but U35 also increased ventricular cavity sizes (left ventricular end-diastolic volume (EDV)i +3%; left ventricular end-systolic volume (ESV)i +8%; right ventricular end-diastolic volume (EDV)i +4%; right ventricular end-systolic volume (ESV)i +5%; P &lt; 0.01 for all). Systemic aortic compliance fell in the whole sample by 7% (P = 0.020) and, especially in O35, also systemic vascular resistance (–4% in the whole sample, P = 0.04) and blood pressure (systolic/diastolic, whole sample: brachial –4/–3 mmHg, central –4/–2 mmHg, all P &lt; 0.001; O35: brachial –6/–3 mmHg, central –6/–4 mmHg, all P &lt; 0.001).

Conclusion
Medium-term, unsupervised physical training in healthy sedentary individuals induces measurable remodelling of both heart and vasculature. This amount is age dependent, with predominant cardiac remodelling when younger and predominantly vascular remodelling when older.

Background: The use of silver diamine fluoride (SDF) as a nonsurgical caries management product is growing. Evidence suggests that SDF is very successful in arresting caries. However, a common concern with SDF treatment is the unaesthetic black staining. The purpose of this qualitative study was to determine parents’ views following their children’s treatment with SDF to manage severe early childhood caries (ECC). Method: Parents were interviewed as part of a mixed-method study of SDF to arrest severe ECC. Children with caries lesions in primary teeth were treated with 2 applications of 38% SDF, followed by fluoride varnish. Semistructured in-person and phone interviews were conducted with 19 parents of children in the study. Data were transcribed verbatim and manually coded and uploaded to NVivo 12 for further coding analysis. Results: None of the parents had previously heard about SDF, and they learned about it from the study dentist. Although parents trusted the dentist’s information on SDF, they welcomed additional evidence, especially relating to product safety and effectiveness. Some parents were minimally concerned with the black staining caused by SDF treatment. It was more important that SDF arrested caries progression, minimized pain and sensitivity, and prevented dental infection. However, some parents expressed concerns related to the unaesthetic black staining. Interestingly, many parents indicated that their children were not overly concerned with the black staining. A majority of parents said that they would recommend the treatment to others. Conclusion: This is the first qualitative study involving parents of children who were treated with SDF. Most parents were accepting of SDF as a nonsurgical treatment to arrest caries and minimize dentinal sensitivity secondary to caries, although some expressed concern about the black staining in anterior teeth. It is important to adequately inform parents of the negative aesthetic consequences and obtain informed consent before treatment. Knowledge Transfer Statement: This qualitative study revealed that many parents of children with severe ECC are accepting of SDF as a nonrestorative caries management option, despite the black staining of caries lesions. Dental professionals need to be aware of these parental concerns and obtain written informed consent prior to treatment. Parents also requested more information and resources on SDF on its benefits, effectiveness, and any associated risks.

AbstractProgrammed cell death-1 (PD-1)/programmed death ligand-1 blockade may potentially augment graft-vs-tumor effects following allogeneic hematopoietic cell transplantation (alloHCT), but retrospective studies of anti–PD-1 therapy reported substantial toxicity from graft-versus-host-disease (GVHD). Here, we report the results of a prospective clinical trial of PD-1 blockade for relapsed hematologic malignancies (HMs) after alloHCT (NCT01822509). The primary objective in this phase 1 multicenter, investigator-initiated study was to determine maximum tolerated dose and safety. Secondary objectives were to assess efficacy and immunologic activity. Patients with relapsed HMs following alloHCT were eligible. Nivolumab was administered every 2 weeks until progression or unacceptable toxicity, starting with a 1-mg/kg cohort, with planned deescalation based on toxicity to a 0.5-mg/kg cohort. Twenty-eight patients were treated (n = 19 myeloid, n = 9 lymphoid). Median age was 57 years (range 27-76), and median time from alloHCT to enrollment was 21 months (range 5.6-108.5). Two of 6 patients treated at 1 mg/kg experienced dose-limiting toxicity (DLT) from immune-related adverse events (irAEs). Twenty-two patients were treated at 0.5 mg/kg, and 4 DLTs occurred, including 2 irAEs and 2 with fatal GVHD. The overall response rate in efficacy-evaluable patients was 32% (8/25). With a median follow-up of 11 months, the 1-year progression-free survival and overall survival were 23% and 56%, respectively. In this first prospective clinical trial of an anti–PD-1 antibody for post–alloHCT relapse, GVHD and irAEs occurred, requiring dose deescalation, with only modest antitumor activity. Further studies of anti–PD-1 therapy post–alloHCT may require specific toxicity mitigation strategies. This trial was registered at www.clinicaltrials.gov as #NCT 01822509.
Estimates of the ongoing need for social distancing and control measures post-“lockdown” from trajectories of COVID-19 cases and mortality
Authors: Lonergan Mike , Chalmers James D. 
Published: June 2020

By 21 May 2020, severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) had caused more than 5 million cases of coronavirus 2019 (COVID-19) across more than 200 countries. Most countries with significant outbreaks have introduced social distancing or “lockdown” measures to reduce viral transmission. So the key question now is when, how and to what extent these measures can be lifted.Publicly available data on daily numbers of newly confirmed cases and mortality were used to fit regression models estimating trajectories, doubling times and the reproduction number (R0) of the disease, before and under the control measures. These data ran up to 21 May 2020, and were sufficient for analysis in 89 countries.The estimates of R0before lockdown based on these data were broadly consistent with those previously published: between 2.0 and 3.7 in the countries with the largest number of cases available for analysis (USA, Italy, Spain, France and UK). There was little evidence to suggest that the restrictions had reduced R far below 1 in many places, with France having the most rapid reductions: R00.76 (95% CI 0.72–0.82) based on cases, and 0.77 (95% CI 0.73–0.80) based on mortality.Intermittent lockdown has been proposed as a means of controlling the outbreak while allowing periods of increased freedom and economic activity. These data suggest that few countries could have even 1 week per month unrestricted without seeing resurgence of the epidemic. Similarly, restoring 20% of the activity that has been prevented by the lockdowns looks difficult to reconcile with preventing the resurgence of the disease in most countries.
