Colonoscopic cancer detection rate: a new performance measure - is it FIT for purpose?

Introduction: Gastrointestinal symptoms correlate poorly with cancer diagnosis. A faecal immunochemical test (FIT) result of ≥10 µg has high sensitivity and negative predictive value for colorectal cancer (CRC) detection. An FIT-based diagnostic pathway may lead to more effective resource utilisation. We aimed to use National Endoscopy Database (NED) data to create a new colonoscopy performance measure, cancer detection rate (CDR) to assess the appropriate identification of target populations for colonoscopy; then to use CDR to assess the impact of implementing an FIT-based referral pathway locally. Methods: NED data were analysed to compare local diagnostic colonoscopic CDR in 2019 (prepathway revision) and 2021 (postpathway revision), benchmarked against overall national CDR for the same time frames. Results: 1, 123, 624 NED diagnostic colonoscopies were analysed. Locally, there was a significant increase in CDR between 2019 and 2021, from 3.01% (2.45%-3.47%) to 4.32% (3.69%-4.95%), p=0.003. The CDR increase was due to both a 10% increase in the number of CRCs detected and a 25% reduction in the number of diagnostic colonoscopies performed. Nationally, there was a smaller, but significant, increase in CDR from 2.02% (1.99%-2.07%) to 2.33% (2.29%-2.37%), p<0.001. The rate of increase in CDR% between 2019 and 2021 was significantly different locally compared with nationally. Conclusion: Our study indicates that the introduction of a robustly vetted FIT-based algorithm to determine whether diagnostic colonoscopy is required, is effective in increasing the colonoscopic CDR. Moreover, CDR appears to be a meaningful performance metric that can be automatically calculated through NED, enabling monitoring of the quality of referral and vetting pathways.

Identifying high cholesterol in the ambulance setting: a mixed-methods cohort study to tackle health inequality.

BACKGROUND: Individuals with low socio-economic status (SES) have disproportionate rates of cardio- vascular disease (CVD) but poorer engagement with preventative health. This study aimed to compare characteristics of individuals with and without hyperlipidaemia and describe their health behaviours. METHODS: A mixed-methods study between January and December 2022. Patients aged ≥40 years using the ambulance service with blood pressure of ≥140/90 had their total cholesterol measured using a point of care device. Data including blood pressure, smoking status, National Early Warning Score 2 and clinical frailty scale (CFS) were analysed. RESULTS: Of 203 patients (59% female, mean age 65.7 years), 115 (56.7%) had total cholesterol ≥5.1 mmol/L. Thirty patients (14.8%) sought treatment and received either statins (n = 9; 4.4%), dietary modification (n = 7; 3.4%) or no further intervention (n = 14; 6.9%), whilst 85 patients (41.9%) took no further action. Lower CFS (OR 0.53 [0.31-0.93]) and higher total cholesterol (OR 2.07 [1.03-2.76]) predicted seeking further management. SES was not associated with hyperlipidaemia or likelihood of seeking further management, rather this was dictated by competing co-morbidity, poor health literacy and digital divide. CONCLUSIONS: Undiagnosed hyperlipidaemia exists in patients using the ambulance service, irrespective of SES. Individual and healthcare system factors prevent engagement in cholesterol lowering behaviours.

Patient experience of pain during vaginal pessary removal and insertion: a service evaluation study.

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse is a common problem affecting women, but there is currently a lack of research focusing on patient experience of pessary changes. This study was aimed at capturing the patient perspective of pessary changes and formally assessing pain during pessary removal and insertion. METHODS: A service evaluation request was granted by South Tees Hospitals NHS Trust. Patients undergoing pessary change (ring, shelf, or Gellhorn) in gynaecology outpatient clinics over a 6-month period were asked to rate their pain scores on a ten-point numerical pain-rating scale. Other associated data were collected. RESULTS: Out of 213 women, 58.2% reported that pessary removal was more painful than insertion, 30.5% reported equal pain, and 10.8% reported that insertion was more painful than removal. Pain scores were significantly higher for removal (mean 4.37, median 4, IQR 4-7) than for insertion (mean 2.66, median 2, IQR 2-4, p <0.001). Ring pessaries were significantly less painful to both remove and insert than shelf and Gellhorn pessaries. Smaller pessaries were more painful to both remove and insert. There was no significant difference in pain scores reported by those with or without diagnosed vulval conditions. CONCLUSIONS: Pessary removal causes most women moderate pain, which should be communicated to patients beforehand. Ring pessaries are significantly less painful to change than other pessary types. Clinicians should consider pain as a factor in their decision-making surrounding pessary choice and when counselling patients. Future research should focus on ways to reduce pain during pessary removal.

A Retrospective Database Analysis to Investigate Treatment Patterns and Health Care Resource Utilisation in Patients who CYCLe AntiMuscarinics in ENgland (CYCLAMEN).

BACKGROUND: Patients with overactive bladder may cycle through different antimuscarinic medications even though there is limited evidence to support this approach. OBJECTIVE: To describe treatment patterns and the associated health care resource utilisation (HCRU) according to antimuscarinic cycling groups. DESIGN, SETTING, AND PARTICIPANTS: The CYCLe AntiMuscarinics in ENgland (CYCLAMEN) study was a retrospective observational investigation that used primary care records from the Clinical Practice Research Datalink GOLD database linked to Hospital Episode Statistics secondary care data. Eligible patients (≥18 yr) were prescribed their first antimuscarinic between January 2014 and December 2017. Patients were categorised into groups prescribed one, two, or three or more (groups 1-3) consecutive unique antimuscarinics over 18 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The HCRU rate and costs were calculated for the period of continuous antimuscarinic therapy (first antimuscarinic treatment episode) and the 18-mo follow-up period. Treatment sequence patterns were displayed using sunburst plots and Kaplan-Meier analysis was used to assess time on treatment. RESULTS AND LIMITATIONS: Overall, 35 369 patients were included, of whom 31 760 (89.8%) received one antimuscarinic (group 1), 3182 (9.0%) received two (group 2), and 427 (1.2%) received three or more (group 3). The most common initial antimuscarinics were solifenacin (13 628 patients, 42.9%) in group 1, and oxybutynin in group 2 (1267 patients, 39.8%) and group 3 (200 patients, 46.8%). The median duration of the first antimuscarinic treatment episode was 57 d and <20% of patients were receiving any antimuscarinic after 18 mo. The number of primary care visits and mean costs increased across groups. The reasons for cycling could not be identified in this study. CONCLUSIONS: Approximately 10% of patients underwent sequential cycling with two or more antimuscarinics. Furthermore, as the majority discontinued treatment within 18 mo, there is a need to improve the management of these patients in the clinical care setting. PATIENT SUMMARY: We investigated treatment patterns and health care use for patients with overactive bladder who were prescribed at least one antimuscarinic drug (AMD), which are drugs that reduce some of the impulses passing from the bladder to the brain. Around 10% of patients accessing primary health care in England received more than one sequential AMD. Most patients discontinued treatment, which may indicate inadequate management of their condition. Prescription of a higher number of AMDs was associated with higher health care costs.

Increased adverse events following third dose of BNT162b2/Pfizer vaccine in those with previous COVID-19, but not with concurrent influenza vaccine.

Prior studies suggest that adverse events (AEs) following doses one and two of BNT162b2/Pfizer vaccine are worse in those with a prior history of COVID-19. To establish whether this outcome applies to a third/booster dose, we conducted a survey with 534 healthcare workers (HCW) in Northeast England, who reported AEs following all three doses of BNT162b2/Pfizer vaccine. We also explored AEs associated with concurrent seasonal influenza immunisation, in a subset of 492 HCWs. For all doses of BNT162b2/Pfizer vaccine there was a cluster of systemic AEs that were consistently worse in HCWs with a prior history of COVID-19. AEs were no worse in HCWs who received their third/booster dose within 7 days of the influenza jab, rather than further apart. Gender and the presence of ongoing COVID-19 symptoms (OCS) had no effect on AEs associated with COVID-19 or influenza vaccination, though younger HCWs experienced more AEs overall. Our findings have implications for vaccine hesitancy and immunisation protocols.

'I felt like I deserved it because I was autistic': Understanding the impact of interpersonal victimisation in the lives of autistic people.

LAY ABSTRACT: Research suggests that autistic people are more likely to be hurt by someone they know (e.g. a friend or a family member) compared to non-autistic people. In this study, we wanted to know how being hurt by someone you know affects autistic people, and what might help them recover. In total, 102 autistic people took part in an interview, where we asked questions like how being hurt by people they know had made them feel and whether anyone they had asked for help had done a good job of supporting them. We analysed what they had said using thematic analysis, which involved reading what everyone said and looking for common themes. Our findings showed that a lot of autistic people think it is normal to be hurt by people you know because it has happened to them so much. This makes many autistic people feel like they need to mask parts of themselves to stay safe, but this also makes them really exhausted. It took some people a long time to realise what had happened to them was wrong, and it was hard to ask for help. People who did ask for help often had bad experiences with professionals (e.g. police) who did not know much about autistic people. They said better support would come from creating more autistic-run support groups and educating people about autism. These findings are important for working out how to help people who have been hurt by people they know.

The small HDL particle hypothesis of Alzheimer's disease.

We propose the hypothesis that small high-density lipoprotein (HDL) particles reduce the risk of Alzheimer's disease (AD) by virtue of their capacity to exchange lipids, affecting neuronal membrane composition and vascular and synaptic functions. Concentrations of small HDLs in cerebrospinal fluid (CSF) and plasma were measured in 180 individuals ≥60 years of age using ion mobility methodology. Small HDL concentrations in CSF were positively associated with performance in three domains of cognitive function independent of apolipoprotein E (APOE) ε4 status, age, sex, and years of education. Moreover, there was a significant correlation between levels of small HDLs in CSF and plasma. Further studies will be aimed at determining whether specific components of small HDL exchange across the blood, brain, and CSF barriers, and developing approaches to exploit small HDLs for therapeutic purposes.

Integrated Quantitative Targeted Lipidomics and Proteomics Reveal Unique Fingerprints of Multiple Metabolic Conditions.

Aberrations in lipid and lipoprotein metabolic pathways can lead to numerous diseases, including cardiovascular disease, diabetes, neurological disorders, and cancer. The integration of quantitative lipid and lipoprotein profiling of human plasma may provide a powerful approach to inform early disease diagnosis and prevention. In this study, we leveraged data-driven quantitative targeted lipidomics and proteomics to identify specific molecular changes associated with different metabolic risk categories, including hyperlipidemic, hypercholesterolemic, hypertriglyceridemic, hyperglycemic, and normolipidemic conditions. Based on the quantitative characterization of serum samples from 146 individuals, we have determined individual lipid species and proteins that were significantly up- or down-regulated relative to the normolipidemic group. Then, we established protein-lipid topological networks for each metabolic category and linked dysregulated proteins and lipids with defined metabolic pathways. To evaluate the differentiating power of integrated lipidomics and proteomics data, we have built an artificial neural network model that simultaneously and accurately categorized the samples from each metabolic risk category based on the determined lipidomics and proteomics profiles. Together, our findings provide new insights into molecular changes associated with metabolic risk conditions, suggest new condition-specific associations between apolipoproteins and lipids, and may inform new biomarker discovery in lipid metabolism-associated disorders.

"This Was Just How This Friendship Worked": Experiences of Interpersonal Victimization Among Autistic Adults.

Background: The victimization of autistic people by familiar others (interpersonal victimization) is an understudied phenomenon despite suggestions that prevalence rates may be disproportionately high. We know very little about the way autistic people perceive these experiences, and how to support them. The aim of the current study was to explore experiences of interpersonal victimization among autistic adults from their own perspective. Methods: We recruited 43 autistic adults to take part in a qualitative online study, and asked about their experiences of being victimized or taken advantage of by people they know in the past. We analyzed their comments at the semantic level using inductive thematic analysis, from a critical realist perspective. Results: We identified two key themes in the data. The first theme, "cycles of victimization" highlighted the occurrence of polyvictimization in the sample. The second ("perceptions of victimization") focused on how these experiences were related to difficulties with trust (of both self and others), the recognition of victimization, and heightened compliance. The participants expressed difficulty with saying no to people, and found it difficult to identify when someone had negative or manipulative intentions. Conclusions: Our findings suggest that autistic adults experience victimization from a range of close others, and may find it difficult to recognize when someone is acting in an abusive manner. Many participants had experienced heightened compliance in response to unreasonable requests from others, however, reasons for this were varied (e.g., fear and desire to avoid confrontation) and require further investigation. These findings have implications for developing supports that enable autistic adults to recognize their own boundaries and advocate for themselves, in addition to helping them to recognize what a healthy relationship looks like.

Why was this study done?: We think that many autistic people experience being hurt by people they know. This can include both physical harm such as hitting, and emotional harm such as being called horrible things. We currently know very little about these experiences, even though we think it happens a lot. What was the purpose of this study?: The purpose of this study was to find out more about the experiences of autistic people who have been hurt by someone they know, from their own point of view. What did the researchers do?: Using an online survey, we invited autistic adults who had been hurt by someone they know to write about what had happened to them from their own point of view. Forty-three autistic people wrote about their experiences and we analyzed these data by reading what they had said and looking for patterns (themes) across people. What were the results of this study?: Many of the participants told us that they had been hurt more than once, by different people (e.g., their parents, and people they thought were friends). Some participants said that they found it difficult to tell whether someone is treating them badly, and to trust their own judgment about other people's behavior. Some people said that they felt like they had do what other people told them to do. Some did this to avoid getting other people into trouble, whereas others did it because they were scared of what would happen if they said no. What do these findings add to what was already known?: Previous studies have shown that lots of autistic people have been hurt by people they know, and that this has a negative impact on their mental health. Researchers have also asked autistic people what might put them at risk of being hurt by people they know, and how to prevent it. To our knowledge, this is the first study to directly ask autistic people about their own experiences of being hurt by people they know, and highlights what they feel is important for us to know about it. What are potential weaknesses in this study?: We do not know very much about the people who took part aside from their age and gender (e.g., what their race or ethnicity is), and we do not know much about the people who victimized them (e.g., whether they were neurotypical or autistic themselves), or exactly when it happened. How will these findings help autistic people now or in the future?: The findings from this study could be used to think about how we can support autistic people in saying no if someone tells them to do something they do not want to do. They can also be used to find ways to help people to recognize when other people are being hurtful. Finally, we hope that reading this study will make other researchers and practitioners interested in learning how to support autistic people who have been hurt by people they know.

Prior COVID-19 infection is associated with increased Adverse Events (AEs) after the first, but not the second, dose of the BNT162b2/Pfizer vaccine.

The BNT162b2/Pfizer SARS-CoV-2 vaccine has been widely used in the UK, particularly amongst healthcare workers (HCWs). To establish whether previous COVID-19 influenced vaccine-associated Adverse Events (AEs), we conducted a survey-based study of HCWs in Northeast England. Out of 1238 HCWs, 32% self-reported prior positive PCR and/or antibody test for SARS-CoV-2. Post-dose AEs were worse in those with prior COVID-19 after the first, but not the second dose of vaccine. Second dose AEs were greater in frequency/severity, regardless of COVID-19 history, and they were more systemic in nature. Women and younger HCW were more likely to report AEs after both doses, while dosing interval had no effect on AEs. Ongoing Symptomatic COVID-19 was associated with greater frequency/severity of AEs after dose 2, but not dose one. Overall, AEs were self-limiting and short-lived (i.e.,<48 h) in nature. These findings have implications for vaccine hesitancy and informing guidelines for recommended dosing protocols.

Stability of lipids in plasma and serum: Effects of temperature-related storage conditions on the human lipidome.

Large epidemiological studies often require sample transportation and storage, presenting unique considerations when applying advanced lipidomics techniques. The goal of this study was to acquire lipidomics data on plasma and serum samples stored at potential preanalytical conditions (e.g., thawing, extracting, evaporating), systematically monitoring lipid species for a period of one month. Split aliquots of 10 plasma samples and 10 serum samples from healthy individuals were kept in three temperature-related environments: refrigerator, laboratory benchtop, or heated incubator. Samples were analyzed at six different time points over 28 days using a Bligh & Dyer lipid extraction protocol followed by direct infusion into a lipidomics platform using differential mobility with tandem mass spectrometry. The observed concentration changes over time were evaluated relative to method and inter-individual biological variability. In addition, to evaluate the effect of lipase enzyme levels on concentration changes during storage, we compared corresponding fasting and post-prandial plasma samples collected from 5 individuals. Based on our data, a series of low abundance free fatty acid (FFA), diacylglycerol (DAG), and cholesteryl ester (CE) species were identified as potential analytical markers for degradation. These FFA and DAG species are typically produced by endogenous lipases from numerous triacylglycerols (TAGs), and certain high abundance phosphatidylcholines (PCs). The low concentration CEs, which appeared to increase several fold, were likely mass-isobars from oxidation of other high concentration CEs. Although the concentration changes of the high abundant TAG, PC, and CE precursors remained within method variability, the concentration trends of FFA, DAG, and oxidized CE products should be systematically monitored over time to inform analysts about possible pre-analytical biases due to degradation in the study sample sets.

Surgical interventions for lamellar macular holes.

BACKGROUND: Lamellar macular holes (LMHs) are small, partial-thickness defects of the macula defined by characteristic features on optical coherence tomography (OCT), including a newly recognised type of epiretinal membrane termed 'epiretinal proliferation'. There may be a rationale to recommend surgery for individuals with LMHs, particularly those with functional or anatomical deterioration, or poor baseline vision causing significant disability, to stabilise the LMH and prevent further visual deterioration; however, there is currently no evidence-based consensus. OBJECTIVES: To assess the effect of surgical interventions on post-operative visual and anatomical outcomes in people with a confirmed LMH. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Ovid, Embase Ovid, Scopus SciVerse, ISRCTN registry, US National Institutes of Health Ongoing Trials Register, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We also searched reference lists of included trials to identify other eligible trials which our search strategy may have missed. The date of the search was 20 July 2021. SELECTION CRITERIA: We included randomised controlled trials (RCTs) involving participants with a confirmed LMH diagnosis which reported one or more surgical intervention(s), alone or in combination, in at least one arm of the RCT. DATA COLLECTION AND ANALYSIS: We used standard methods as expected by Cochrane. Two study authors independently extracted data and assessed the risk of bias for included trials. Trial authors were contacted for further information and clarification. MAIN RESULTS: A single RCT was eligible for inclusion. Thirty-six participants were randomised in a 2:1 ratio; 24 were allocated to undergo surgery (pars plana vitrectomy, peeling of the epiretial proliferation followed by fovea-sparing removal of the internal limiting membrane) and 12 (10 following two participant dropouts) to observation. Overall, the certainty of the evidence was low for all outcomes due to selection and detection bias, and the low number of participants enrolled in the study which may affect the accuracy of results and reliability of conclusions. At six-month follow-up, change in vision was better in the surgery group (-0.27 logMAR improvement) than observation (0.02 worsening) (mean difference (MD): -0.29 logMAR, 95% confidence intervals (CI): -0.33 to -0.25). Central retinal thickness increased in the surgery group over 6 months 126 µm increase) compared with observation group (decrease by 11µm) (MD: 137 µm, 95% CI: 125.87 µm to 148.13 µm). Finally, at six-month follow-up, retinal sensitivity was better in the surgery group (3.03 dB increase) compared with the observation group (0.06 dB decrease) (MD: 3.09 dB, 95% CI: 2.07 to 4.11 dB). Vision-related quality of life and metamorphopsia were not reported. No adverse outcomes or complications were reported in the study, however, authors could not provide information on whether any individuals developed deterioration in vision of 0.2 logMAR or worse. AUTHORS' CONCLUSIONS: The included single trial demonstrated improvements in visual and anatomical outcome measures for participants with a LMH who underwent surgery compared with observation only. Therefore, we can conclude that participants who undergo surgery may achieve superior post-operative best corrected visual acuity and anatomical outcomes compared with observation only. However, the results of a single and small RCT provides limited evidence to support or refute surgery as an effective management option for LMHs. Future RCTs with a larger number of participants and with fewer methodological limitations and biases are necessary to inform future clinical practice.

Prevalence of histological abnormalities in hysterectomy specimens performed for prolapse. A systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: The practice of histopathological assessment of the uterus following hysterectomy for benign indications including pelvic organ prolapse (POP) surgery is common and often routine. While pathology is not anticipated, the finding of pathology requiring further action is always a concern, in particular CIN (cervical intraepithelial neoplasia) or cervical/uterine malignancy. We aimed to perform a systematic review to understand the prevalence of actionable uterine and cervical pathology in hysterectomy specimens performed for POP. METHODS: A literature search was performed in January 2020 of MEDLINE, Embase and CINAHL using the Healthcare Databases Advanced Search platform. Included studies reported CIN and/or uterine/cervical malignancy in histological assessment of hysterectomy specimens performed purely for POP. Meta-analysis of prevalence was performed using the MetaXL ( www.epigear.com ) add-in for Microsoft Excel. RESULTS: Six hundred seventy-seven records were identified, out of which 34 studies were eligible. Overall prevalence (95% confidence interval [CI]) of endometrial cancer in 33 studies was 0.004 (0.003-0.006), I2 = 41%, number needed to treat (NNT) 1:250. Total actionable uterine pathology was 0.005 (0.003-0.006) in 33 studies, I2 = 35%, NNT = 1:200. Overall prevalence of cervical cancer in 19 papers was 0.001 (0.000-0.002), I2 = 18%, NNT = 1:1000. In 16 studies the overall prevalence of CIN was 0.013 (0.001-0.033), I2 = 95%, NNT = 1:77. Prevalence of total actionable pathology was 0.013 (0.006-0.0023), I2 = 86%, NNT = 1:77. CONCLUSION: The risk of actionable pathology is low, but not negligible. The variation between populations is wide. The prevalence of finding such pathology supports the routine practice of sending all hysterectomy specimens performed for POP for histological assessment.

"Masking Is Life": Experiences of Masking in Autistic and Nonautistic Adults.

Background: Autistic masking is an emerging research area, and so far, research has suggested that masking has a negative effect on autistic people. Masking relates to general social practices (such as identity management) and is often driven by stigma avoidance. Many nonautistic people also experience stigma that might drive them to suppress aspects of their identity. In this study, we investigate similarities and differences in experiences of masking in autistic and nonautistic people. Methods: We conducted an online survey about experiences and views of masking in autistic people (n = 144), neurodivergent people without an autism diagnosis (n = 49), and neurotypical people (n = 45) recruited via social media. We used thematic analysis to analyze responses to open-ended items about masking, using an inductive approach, at a semantic level, with a critical realist paradigm. Results: Thematic analysis revealed that some aspects of masking are shared across autistic and nonautistic people, such as utilizing mimicry of others as a social strategy or feeling exhausted from masking. All groups reported that masking made them feel disconnected from their true sense of identity and had a negative effect on them. Other aspects of masking seemed more specific to autistic people, such as sensory suppression, and masking leading to suicidal ideation. Conclusions: Our findings suggest that many aspects of masking are experienced across different neurotypes and are likely related to outside perceptions of difference and stigma. It is likely that what we call "autistic masking" is similar to other forms of stigma management previously theorized. Some aspects of masking do seem more specific to the autistic neurotype (e.g., suppression of stimming) and should be explored further to provide support for autistic people recovering from the negative impact of masking. Lay summary: Why was this study done?: Masking is the process of intentionally, or unintentionally, hiding aspects of yourself to avoid harm. Recent research has suggested that autistic people might mask a lot and that this can lead to long-term problems in mental health. At the moment, we do not know which parts of masking are specific to autistic people, and which parts might be experienced by others, especially other neurodivergent people who are not autistic, for example, people with attention-deficit hyperactivity disorder (ADHD).What was the purpose of this study?: The purpose of this study was to find out about masking in autistic and nonautistic people, to find out whether some parts of masking are specific to autistic people, or experienced by others.What did the researchers do?: We conducted an online survey about masking with three groups of people: autistic people, nonautistic people who have another neurodevelopmental or mental health diagnosis, such as dyslexia, ADHD, or depression, and nonautistic people who do not have any neurodevelopmental or mental health diagnoses. The survey included an open text box for people to write about their experiences of masking and their opinions about masking. We analyzed these responses using a method called "thematic analysis." This method helps us look for ideas that people commonly talk about in their answers.What were the results of this study?: We found out that autistic and nonautistic people think masking is very complicated and has a negative effect on them. Both autistic and nonautistic people said that masking made them exhausted and really unhappy and that it made them feel like people did not know the "real them." Only autistic people mentioned that masking sometimes makes them feel suicidal and that masking includes things that other groups did not mention (such as trying to hide being upset by sensory things such as loud noise).What do these findings add to what was already known?: Our findings suggest that some aspects of masking do not just affect autistic people (such as feeling like people do not know the real you), but other parts might be more unique to autistic people (such as hiding stims from other people).What are potential weaknesses in this study?: More women than men and nonbinary people took part, which means that we know more about women than other people. We also do not really know whether everyone in the nonautistic groups were really "not autistic." They could be autistic people who do not have a diagnosis, which might affect our results.How will these findings help autistic people now or in the future?: We hope our findings will help people to understand how masking affects autistic and nonautistic people. We also hope that people designing new studies will look at important things such as whether someone is autistic and nonbinary, or autistic and ADHD as these things might affect their experiences.

The Association between Foveal Floor Measurements and Macular Hole Size.

PURPOSE: Determining which factors influence idiopathic macular hole (MH) size is important because it is a major prognostic indicator of treatment success. Foveal pit morphologic features are highly symmetrical within individuals and may influence idiopathic MH size. Using a series of patients with unilateral idiopathic MHs, we examined the foveal floor size of the fellow eye to evaluate its relationship with idiopathic MH size and postoperative outcomes. DESIGN: Retrospective observational study. PARTICIPANTS: Two hundred forty-one participants with a unilateral idiopathic MH treated with surgery and a fellow eye with no ocular pathologic features. METHODS: Both eyes underwent spectral-domain (SD) OCT imaging at the time of surgery. Minimum linear diameter (MLD) and base diameter (BD) defined idiopathic MH size. Foveal floor width (FFW) and minimal foveal thickness defined foveal pit morphologic features of the fellow eye. MAIN OUTCOME MEASURES: Baseline characteristics, SD OCT measurements, and preoperative variables were compared to determine their relationship with idiopathic MH size and postoperative visual acuity (VA) in logarithm of the minimum angle of resolution units. RESULTS: Foveal floor width was correlated with MLD (r = 0.36; P ≤ 0.001) and BD (r = 0.30; P ≤ 0.001), but not postoperative VA. Minimum linear diameter correlated with preoperative VA (r = 0.49; P ≤ 0.0001) and postoperative VA (r = 0.54; P ≤ 0.0001). A 2-stage regression model was developed to predict postoperative VA (r2 = 0.28): preoperative VA (ß = 0.36; P = 0.002) explained 13% of variability and MLD (ß = 0.29; P = 0.002), and idiopathic MH duration (ß = 0.23; P = 0.004) explained a further 16%. CONCLUSIONS: Foveal floor width of the fellow eye in patients with a unilateral idiopathic MH was correlated significantly with idiopathic MH size and may explain some of the variability in idiopathic MH size observed between individuals. However, FFW could not predict postoperative vision.

Impact of a community-acquired pneumonia care bundle in North East England from 2014 to 2017-A quality improvement project.

OBJECTIVES: To explore the impact of implementation of Community-Acquired Pneumonia (CAP) quality care bundle. SETTING: Eight acute hospitals in the North East of England and North Cumbria. PARTICIPANTS: ICD-10 coded CAP aged >18 were identified. A total of 16 201 CAP patients were discharged 2016/2017 (15 707; 2015/2016 and 10 733; 2014/2015). OUTCOME MEASURES: Secondary User Service (SUS) data were collected monthly from April 2014 to 2017. Data were pseudonymised and data flows governed by Data Sharing Agreements. CAP measures were based on British Thoracic Society guidance and agreed following clinician consultation. CAP admissions and individual organisational compliance with and impact of, CAP quality bundle measures was explored. RESULTS: Average length of stay (LOS) was 10.4 days (median 6) 25% >13 days. Crude in-hospital mortality rate was 17.6%, significantly lower (95% CI) than 19.1% in 2015/2016 and 19.3% in 2014/2015. Emergency readmissions within 28 days were 19.7% (19.2%; 2015/2016, 17.9%; 2014/2015). A total of 39.5% of patients received all appropriate care measures. Compliance has improved over time, although not for all hospitals. Most quality measures have higher mortality for those passing measures compared to those failing (P < .05 95% CI). Giving oxygen, had a significantly higher emergency readmission rate, 3.3% higher (95% CI 1.1% to 5.5%). Appropriate antibiotics and recording CURB-65 scores reduced the emergency readmission rates (-2.7% (95% CI -4.5% to -0.8%) -2.6% (95% CI -3.8% to -1.4%), respectively, (P = ns)). CONCLUSION: CAP accounts for significant bed days, mortality and readmissions. Although mortality was lower, LOS and readmission rates were not, despite improvements in compliance after implementation of the care bundle. Care bundle use remained sub-optimal.

The Effect of Internal Limiting Membrane Cleaning on Epiretinal Membrane Formation after Vitrectomy for Proliferative Diabetic Retinopathy.

PURPOSE: We hypothesised that cleaning the internal limiting membrane (ILM) with a flexible nitinol loop following diabetic vitrectomy without peeling may reduce the common occurrence of postoperative epiretinal membrane (ERM) formation. METHODS: Consecutive patients undergoing vitrectomy for proliferative diabetic retinopathy by one surgeon from 2015 to 2019 were studied and divided into 2 cohorts: the control group underwent standard surgery, and the ILM clean group underwent additional cleaning of the macular retina using a flexible nitinol loop after vitrectomy. Masked comparison of ERM on optical coherence tomography was performed at 3 months, and visual acuity (VA) was measured until 12 months postoperatively. RESULTS: Baseline demographics, clinical features, and protein levels were similar between cohorts. The ILM clean group (n = 56) had fewer clinically significant ERM than the control group (n = 50; 4 vs. 20%; p = 0.01), and a significantly lower proportion of the ILM clean group required revision surgery (2 vs. 14%; p = 0.02). VA in the ILM clean group was significantly better than in the control group at 3 months (0.35 vs. 0.50 logMAR; p = 0.02) but not at 12 months (0.34 vs. 0.43 logMAR; p = 0.17). CONCLUSION: ILM cleaning with a flexible nitinol loop following diabetic vitrectomy resulted in significant reduction in ERM formation and reduced necessity for revision surgery. There was significant improvement in VA at 3 months but not over a longer follow-up.
