Challenging assumptions about the demographics of eosinophilic gastrointestinal diseases: A systematic review

Background

The demographic characteristics of patients with eosinophilic gastrointestinal diseases (EGIDs) are poorly understood. Population-based assessments of EGID demographics may indicate health disparities in diagnosis.

Objectives

We aimed to characterize the demographic distribution of EGIDs and evaluate the potential for bias in reporting patient characteristics.

Methods

We conducted a systematic review, extracting data on age, sex, gender, race, ethnicity, body mass index, insurance, and urban/rural residence on EGID patients and the source population. Differences in proportions were assessed by chi-square tests. Demographic reporting was compared to recent guidelines.

Results

Among 50 studies that met inclusion/exclusion criteria, 12 reported ≥1 demographic feature in both EGID and source populations. Except for age and sex or gender, demographics were rarely described (race = 4, ethnicity = 1, insurance = 1) or were not described (body mass index, urban/rural residence). A higher proportion of male subjects was observed for EoE or esophageal eosinophilia relative to the source population, but no difference in gender or sex distribution was observed for other EGIDs. "Sex" and "gender" were used interchangeably, and frequently only the male proportion was reported. Reporting of race and ethnicity was inconsistent with guidelines.

Conclusion

Current data support a male predominance for EoE only. Evidence was insufficient to support enrichment of EGIDs in any particular racial, ethnic, or other demographic group. Population-based studies presenting demographics on both cases and source populations are needed. Implementation of guidelines for more inclusive reporting of demographic characteristics is crucial to prevent disparities in timely diagnosis and management of patients with EGIDs.

An investigation of the clinical impact and therapeutic relevance of a DNA damage immune response (DDIR) signature in patients with advanced gastroesophageal adenocarcinoma

BACKGROUND

An improved understanding of which gastroesophageal adenocarcinoma (GOA) patients respond to both chemotherapy and immune checkpoint inhibitors (ICI) is needed. We investigated the predictive role and underlying biology of a 44-gene DNA damage immune response (DDIR) signature in patients with advanced GOA.

MATERIALS AND METHODS

Transcriptional profiling was carried out on pretreatment tissue from 252 GOA patients treated with platinum-based chemotherapy (three dose levels) within the randomized phase III GO2 trial. Cross-validation was carried out in two independent GOA cohorts with transcriptional profiling, immune cell immunohistochemistry and epidermal growth factor receptor (EGFR) fluorescent in situ hybridization (FISH) (n = 430).

RESULTS

In the GO2 trial, DDIR-positive tumours had a greater radiological response (51.7% versus 28.5%, P = 0.022) and improved overall survival in a dose-dependent manner (P = 0.028). DDIR positivity was associated with a pretreatment inflamed tumour microenvironment (TME) and increased expression of biomarkers associated with ICI response such as CD274 (programmed death-ligand 1, PD-L1) and a microsatellite instability RNA signature. Consensus pathway analysis identified EGFR as a potential key determinant of the DDIR signature. EGFR amplification was associated with DDIR negativity and an immune cold TME.

CONCLUSIONS

Our results indicate the importance of the GOA TME in chemotherapy response, its relationship to DNA damage repair and EGFR as a targetable driver of an immune cold TME. Chemotherapy-sensitive inflamed GOAs could benefit from ICI delivered in combination with standard chemotherapy. Combining EGFR inhibitors and ICIs warrants further investigation in patients with EGFR-amplified tumours.

Expert Recommendations on Use of Topical Therapeutics for Vitiligo in Pediatric, Adolescent, and Young Adult Patients

Importance

Evidence-based recommendations for the treatment of vitiligo in pediatric, adolescent, and young adult patients in the US are needed.

Objective

To develop evidence- and consensus-based expert recommendations on the diagnosis and treatment of vitiligo in young patients.

Evidence Review

A process was developed to produce consensus recommendations addressing questions regarding pediatric vitiligo. A librarian-conducted literature review was performed using articles that met the inclusion criteria: published in English, containing primary data (including meta-analysis) and pediatric-specific data, and analysis of 6 or more patients. Included articles were graded by the Strength of Recommendation Taxonomy criteria and Oxford Centre for Evidence-based Medicine's Levels of Evidence and Grades of Recommendation. Research questions were reviewed on May 9, 2022, through a video conference. One month after the conference, participants participated in an online survey documenting their level of agreement with the generated statements, using a 5-point Likert scale.

Findings

Articles on topical corticosteroids and/or topical calcineurin inhibitors (n = 50), topical Janus kinase inhibitors (n = 5), pseudocatalase (n = 2), and microdermabrasion (n = 2) met inclusion criteria. Forty-two recommendations were made on the diagnosis of vitiligo and optimal topical therapeutics, with 33 recommendations obtaining a 70% or greater composite agreement and strong agreement. Topical calcineurin inhibitors twice daily, topical corticosteroids with time limitation due to atrophy risk, and topical ruxolitinib, 1.5%, cream-used off-label for patients younger than 12 years and limited to nonsegmental vitiligo-were identified as evidence-based first-line therapies in the management of pediatric and adolescent patients, with specific guidance on age-based data, minimum therapeutic trial of 6 months or greater, prolonged therapy to prevent recurrence, and the positive benefit of coordinated use of UV therapeutic sources.

Conclusions and Relevance

Evidence supports the use of topical calcineurin inhibitors, topical corticosteroids, and topical Janus kinase inhibitors as effective therapeutics for vitiligo in pediatric, adolescent, and young adult patients, with specific decisions on choice of agent based on factors such as site location, body surface area, and age.

Fatigue in children who have recently completed treatment for acute lymphoblastic leukemia: a longitudinal study

BACKGROUND

This study examined fatigue in patients treated for childhood acute lymphoblastic leukemia (ALL) over a 2-year period (3- to 27-months post-treatment completion), from the perspective of children and parent caregivers, compared to a healthy comparison group.

METHODS

Eighty-three patients (4-16 years at enrolment) and their parents, reported on the child's fatigue using the Pediatric Quality of Life Inventory- Multidimensional Fatigue Scale (PedsQL-MFS), at 3- 15- and 27-months post-treatment completion, and 53 healthy children and their parents reported on fatigue across the same timepoints.

RESULTS

Parent proxy-reporting showed that parents of ALL patients reported more total fatigue than parents of the comparison group at all time points, with all subscales elevated (general, cognitive, and sleep/rest fatigue). In contrast, patient self-report of fatigue over this period differed from the comparison children for the general fatigue subscale only. Self-reported total fatigue was worse than the comparison group at the 27-month timepoint, with cognitive and sleep/rest fatigue symptoms contributing to this difference. Expected improvements in fatigue over time were not evident in either patient or parent report and no demographic risk factors were identified. Parents and children from both groups reported significantly more fatigue at all time points compared to commonly utilised normative population data.

CONCLUSIONS

Patients treated for childhood ALL are impacted by fatigue symptoms in the post-treatment and early survivorship period. These findings highlight that patients in the 2-years following treatment require increased symptom surveillance and may benefit particularly from interventions that target cognitive and sleep/rest fatigue.

Association Between Social Determinants of Health and Traumatic Brain Injury: A Scoping Review

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Disparities exist in the populations that acquire TBIs, however, with a greater burden and poorer outcomes associated with communities of color and lower socioeconomic status. To combat health inequities such as these, institutions have begun to target social determinants of health (SDoH), which are environmental factors that affect health outcomes and risks. The SDoH may play a role in sustaining a TBI and provide modifiable targets for action to reduce the risk of TBI, especially in high-risk communities. In this study, we describe the existing literature regarding SDoH and their association with sustaining a TBI. We performed a scoping review with a comprehensive search of the Ovid MEDLINE/Embase databases. To summarize the literature, this review adapts the World Health Organization's Commission on SDoH's conceptual framework. Fifty-nine full-text articles, including five focusing on lower and middle-income countries, met our study criteria. Results of the scoping review indicate that several structural determinants of health were associated with TBI risk. Lower educational attainment and income levels were associated with higher odds of TBI. In addition, multiple studies highlight that minority populations were identified as having higher odds of TBI than their White counterparts. Literature highlighting intermediate determinants of health examined in this review describes associations between sustaining a TBI and rurality, work environment, medical conditions, medication/substance use, and adversity. Recommended exploration into lesser-researched SDoH is discussed, and the expansion of this review to other aspects of the TBI continuum is warranted.

Reduction in re-rupture rates following implementation of return-to-sport testing after anterior cruciate ligament reconstruction in 313 patients with a mean follow-up of 50 months

OBJECTIVES

The objective of this study was to assess the mid-term effectiveness of a return to sport (RTS) test in relation to preventing anterior cruciate ligament (ACL) re-rupture and contralateral ACL injury following ACL reconstruction (ACLR). Furthermore, this study aimed to assess the timing of passing a, RTS-test after surgery, and the effect age has on RTS outcomes.

METHODS

Patients undergoing ACLR between August 2014 and December 2018 took an RTS-test following rehabilitation. The RTS-test consisted of the Anterior Cruciate Ligament Return to Sport After Injury Scale, a single-leg hop, a single-leg triple hop, a single-leg triple cross-over hop, a box-drop vertical jump down, a single-leg 4-rep max-incline leg press, and a modified agility T test. RTS-passing criteria were ≥90% limb symmetry index in addition to defined takeoff and landing parameters. Mid-term review assessed sporting level, ACL re-injury, and contralateral ACL injury.

RESULTS

A total of 352 patients underwent RTS-testing, following ACLR with 313 (89%) contactable at follow-up, a mean of 50 months (standard deviation: 11.41, range: 28-76) after surgery. The re-rupture rate was 6.6% after passing the RTS-test and 10.3% following failure (p ​= ​0.24), representing a 36% reduction. Contralateral ACL injury rate after surgery was 6% and was 19% lower in those passing the RTS test. The mean age of patients passing their first RTS-test was significantly higher than that of those who failed (p ​= ​0.0027). Re-ruptures in those who passed the RTS test first time occurred late (>34 months), compared to those who failed first time, which all occurred early (<33 months) (p ​= ​0.0015). The mean age of re-rupture was significantly less than those who did not sustain a re-rupture (p ​= ​0.025).

CONCLUSION

Passing a RTS-test following ACLR reduces ACL re-rupture by 36.21% and contralateral ACL injury by 19.15% at mid-term follow-up. Younger patients are more likely to fail a RTS-test and are at higher risk of contralateral ACL rupture.

Are Population-Level Approaches to Dementia Risk Reduction Under-Researched? A Rapid Review of the Dementia Prevention Literature

Dementia is forecast to become increasingly prevalent, particularly in low- and middle-income countries, and is associated with high human and economic costs. Primary prevention of dementia -preventing risk factors leading to disease development - is an emerging global public health priority. Primary prevention can be achieved in two ways: individual-level or population-level. In this rapid review, we quantify the proportion of contributing interventional evidence to the dementia primary prevention literature that is concerned with either approach. We searched Medline, the National Institute for Health and Care Excellence, Cochrane, the World Health Organization, and Google to identify systematic reviews that described primary prevention interventions for dementia. We used search terms related to dementia risk reduction, intervention/policy, and review. We analysed reference lists of included dementia prevention reviews to identify contributing primary prevention evidence, and categorised these as either individual-level or population-level. Additionally, we examined search strategies to investigate the likelihood of reviews identifying available population-level interventions. We included twelve of the 527 articles retrieved. Population-level evidence was summarised by only two reviews. In these two reviews, <2.5% of the interventions described where population-level interventions. Most search strategies were weighted towards identifying individual-level evidence. Existing systematic reviews of dementia primary prevention interventions include almost no population-level evidence. Correction of this imbalance is needed to ensure that dementia prevention policies can achieve meaningful reductions in the prevalence of, and inequalities in, dementia.

What is a population-level approach to prevention, and how could we apply it to dementia risk reduction?

The World Health Organisation's 2022 'blueprint for dementia research' highlights the need for more research into population-level risk reduction. However, definitions of population-level prevention vary, and application to dementia is challenging because of its multi-factorial aetiology and a maturing prevention evidence base. This paper compares and contrasts key concepts of 'population-level prevention' from the literature, explores related theoretical models and policy frameworks, and applies this to dementia risk reduction. We reach a proposed definition of population-level risk reduction of dementia, which focusses on the need to change societal conditions such that the population is less likely to develop modifiable risk factors known to be associated with dementia, without the need for high-agency behaviour change by individuals. This definition, alongside identified policy frameworks, can inform synthesis of existing evidence and help to co-ordinate the generation of new evidence.

Scoping review and expert-based consensus recommendations for assessment and management of psychogenic non-epileptic (functional) seizures (PNES) in children: A report from the Pediatric Psychiatric Issues Task Force of the International League Against Epilepsy

Limited guidance exists regarding the assessment and management of psychogenic non-epileptic seizures (PNES) in children. Our aim was to develop consensus-based recommendations to fill this gap. The members of the International League Against Epilepsy (ILAE) Task Force on Pediatric Psychiatric Issues conducted a scoping review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-SR) standards. This was supplemented with a Delphi process sent to pediatric PNES experts. Consensus was defined as ≥80% agreement. The systematic search identified 77 studies, the majority (55%) of which were retrospective (only one randomized clinical trial). The primary means of PNES identification was video electroencephalography (vEEG) in 84% of studies. Better outcome was associated with access to counseling/psychological intervention. Children with PNES have more frequent psychiatric disorders than controls. The Delphi resulted in 22 recommendations: Assessment-There was consensus on the importance of (1) taking a comprehensive developmental history; (2) obtaining a description of the events; (3) asking about potential stressors; (4) the need to use vEEG if available parent, self, and school reports and video recordings can contribute to a "probable" diagnosis; and (5) that invasive provocation techniques or deceit should not be employed. Management-There was consensus about the (1) need for a professional with expertise in epilepsy to remain involved for a period after PNES diagnosis; (2) provision of appropriate educational materials to the child and caregivers; and (3) that the decision on treatment modality for PNES in children should consider the child's age, cognitive ability, and family factors. Comorbidities-There was consensus that all children with PNES should be screened for mental health and neurodevelopmental difficulties. Recommendations to facilitate the assessment and management of PNES in children were developed. Future directions to fill knowledge gaps were proposed.

The Prevalence of Nonsuicidal Self-Injury in Military Personnel: A Systematic Review and Meta-Analysis

Military service members and veterans (SMVs) are at risk for self-directed violence, including nonsuicidal self-injury (NSSI). While NSSI is an important construct worthy of independent study, it is understudied among SMVs and, when included in research, typically examined in the context of suicide risk. Consequently, lifetime prevalence rate estimates of NSSI among SMVs vary. This Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review and meta-analysis estimated the average lifetime NSSI prevalence among SMVs and explored demographic and methodological factors that may account for observed variability. Based on a search of Ovid MEDLINE, Embase, PsycINFO, and Web of Science, 47 samples from 42 articles across five countries met inclusion criteria. Results revealed an average NSSI lifetime prevalence rate of 15.76% among SMVs. Significantly higher prevalence rates were observed among clinical (28.14%) versus community (11.28%) samples and studies using interviews to assess NSSI (23.56%) versus self-report (13.44%) or chart review (7.84%). Lifetime prevalence increased as publication year increased and decreased as sample size increased. In contrast to prior literature, prevalence rates were comparable between active-duty SMVs, and studies collecting data anonymously versus those that did not. Lifetime prevalence was not moderated by age, gender, race, country, primary research focus, quality of NSSI operationalization, or whether NSSI methods were assessed. Findings suggest NSSI is a pervasive problem among military personnel, particularly within clinical settings, highlighting the need for systematic assessment of this important but understudied clinical phenomenon among SMVs. Further research is necessary to elucidate additional risk factors for NSSI among SMVs, including trauma exposure.

Systematic review of TNFα-induced paradoxical psoriasis: Treatment outcomes of switching to alternative biologic therapies in inflammatory bowel disease patients

OBJECTIVES

The objective of this systematic review was to evaluate the efficacies of different biologic therapies in treating tumor necrosis factor-alpha (TNFα)-induced paradoxical psoriasis (PXP) and controlling inflammatory bowel disease (IBD) symptoms.

METHODS

We conducted a literature search of the Ovid EMBASE, Ovid Medline, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials databases from their inception to October 3, 2021. We considered all peer-reviewed, randomized controlled trials, chart reviews, and observational studies that discussed the TNFα-induced PXP treatment outcomes in IBD patients of switching to different biologic therapies.

RESULTS

Switching to ustekinumab (UST) resulted in complete or partial resolution of TNFα-induced PXP in 83.1% of patients (74 out of 89 patients), while switching to either vedolizumab (VDZ) or secukinumab led to complete resolution in 100% of patients (eight out of eight patients). Approximately 75.4% of patients who were switched to UST remained in IBD remission, 4.6% in partial remission, and 20.0% in the flare of IBD.

CONCLUSIONS

UST has sufficient data to demonstrate the efficacy in treating TNFα-induced PXP and controlling IBD symptoms concurrently. More data is needed to validate the efficacies of VDZ and SEC in treating TNFα-induced PXP in IBD patients.

Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study

INTRODUCTION

The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures.

METHODS

In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025.

FINDINGS

Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation.

INTERPRETATION

After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

The Use of Telemedicine in Outpatient Pain Management: A Scoping Review

BACKGROUND

Telemedicine is an increasingly important tool in outpatient pain management. Telemedicine can be implemented through various strategies and a multitude of approaches have been described in existing literature.

OBJECTIVES

This scoping review aims to survey how telemedicine has been approached in published literature, providing insight for continued implementation.

STUDY DESIGN

Scoping review.

SETTING

Outpatient pain management.

METHODS

Ovid MEDLINE and Embase databases were queried. Two board-certified pain management physicians screened search results for relevant publications based on predetermined criteria. Included publications focused on outpatient pain management via live video or telephone and reported empirical outcomes. Publications were excluded that focused on acute pain, progressive muscle relaxation, physical therapy, or psychiatry, including cognitive behavioral therapy, or that primarily described educational modules, apps, mobile tracking, or automated calls. Nonfull publications (abstracts) and articles not available in English were also excluded. A third reviewer performed full-text screening, extracting variables of interest. Systematic reviews and meta-analyses were excluded from final selection.

RESULTS

Text and abstract screening of 3,302 results yielded 88 publications. Upon full-text screening, 64 additional publications were excluded, yielding 24 publications. High-quality randomized controlled trials (RCTs) were described in 5 (21%) publications, pilot RCTs in 4 (17%), prospective studies in 1 (4%), retrospective studies in 5 (21%), survey-based studies in 7 (29%), and other types of studies in 2 (8%). Cancer pain was the focus of 3 (13%) studies, headache/facial pain the focus of 4 (17%), musculoskeletal the focus of 3 (13%), and unspecified chronic pain the focus of 14 (58%). Patient experiences were the focus of 18 (75%) publications, provider experiences the focus of 2 (8%), and both patient and provider experiences the focus of 4 (17%). Outcome improvement measures were studied in 17 (71%) publications, process improvement measures in 5 (21%), and both types of measures in 2 (8%). Standard visits without on-site support were described in 4 (17%) publications, while standard visits with on-site support were described in 9 (38%). The remaining 11 (46%) described structured/integrated pain management programs. Positive pain-related outcomes were reported in 9 (38%) studies. Increased access or decreased barriers to care were reported in 9 (38%). Patient satisfaction was reported in 12 (50%) publications, with 10 (42%) describing positive results.

LIMITATIONS

This scoping review focused on telemedicine delivered via telephone or live video communication, excluding a substantial body of literature focused on virtual courses, modules, and other telehealth programs not involving live communication.

CONCLUSIONS

Current literature describes telemedicine implementation with various levels of technological and logistical support. Models of telemedicine represented in current literature include: standard visits with on-site support, standard visits without on-site support, and structured/integrated pain management programs. Presently, no literature has directly compared outcomes from these different approaches. Choice of model will depend on the specific goals and available resources. Patient satisfaction was studied most frequently and generally demonstrated positive results. Though current literature is heterogeneous and lacks RCTs, it consistently demonstrates benefits of telemedicine to patient satisfaction, pain, and access to care.

A novel approach using electroacupuncture for erectile dysfunction after radical prostatectomy: A case report

INTRODUCTION

Research shows that electrical stimulation to damaged peripheral nerves has promising effects on nerve regeneration and recovery of function.

DESCRIPTION

A 71 yr. old male, who was 12 months post left intrafacial and right incremental nerve sparing robotic radical prostatectomy received 6 sessions of sacral electroacupuncture/acupuncture at weekly intervals, commencing 12 months post operatively.

METHODS

CARE guidelines informed the case study report. Positive changes in erectile function after electroacupuncture was recorded using validated scores (IIEF-5 and EHS). Qualitative information was collected via a feedback box.

DISCUSSION

Given that current treatments for post radical prostatectomy erectile dysfunction are invasive and largely unsuccessful, further investigation into electroacupuncture for this population should be pursued.

Anemia in patients with hidradenitis suppurativa : A systematic review with meta-analysis

IMPORTANCE

Hidradenitis suppurativa (HS) is associated with a number of physical and psychological comorbidities. Studies have suggested an association between HS and anemia; however, this association is not widely understood and may result in delayed diagnosis and treatment and possible increase in morbidity and mortality.

OBJECTIVE

To systematically review and perform a meta-analysis regarding the association between HS and anemia, and to characterize the subtypes of anemia associated with HS.

DATA SOURCES

A search of the EMBASE, Medline, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials databases from the time of database inception to September 25, 2022, yielded 313 unique articles.

STUDY SELECTION

All observational studies and randomized controlled trials published in English that examined the odds ratio (OR) of anemia in patients with HS were screened by 2 independent reviewers. Case reports were excluded. Among 313 unique articles, 7 were deemed eligible.

DATA EXTRACTION AND SYNTHESIS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines facilitated data extraction. The Newcastle-Ottawa Scale (NOS) was used to analyze risk of bias of included studies. In addition to OR and 95% confidence intervals, relevant data on patient demographics and anemia subtypes were also extracted.

MAIN OUTCOMES AND MEASURES

The primary outcome was the OR of anemia in HS patients. This study also attempted to characterize anemia subtypes associated with HS.

RESULTS

In total, 2 case-control and 5 cross-sectional studies featured a total of 11,693 patients. Among the studies, 4 of 7 demonstrated a statistically significant positive association between anemia and HS (ORs, 2.20 [1.42-3.41], 2.33 [1.99-2.73], 1.87 [1.02-3.44], and 1.50 [1.43-1.57]), with macrocytic and microcytic subtypes being most common. After adjusting for publication bias, meta-analysis with random effects revealed HS to be associated with increased odds of anemia compared to non-HS groups (OR 1.59 [1.19, 2.11]).

CONCLUSIONS AND RELEVANCE

There is a statistically significant positive association between HS and anemia, particularly for the aforementioned subtypes. Patients with HS should be screened for anemia. In case of lower hemoglobin concentration, the anemia of HS patients should be subdivided according to mean corpuscular volume of the red blood cells and further investigated depending on subtype.

Early Biologic Treatment Decreases Risk of Surgery in Crohn's Disease but not in Ulcerative Colitis: Systematic Review and Meta-Analysis

BACKGROUND AND AIMS

Inflammatory bowel disease (IBD) can lead to long-term complications that significantly impact patients' quality of life and healthcare resource utilization. Prior studies have demonstrated improved short-term outcomes to early exposure of biologics in patients with Crohn's disease (CD) but not in patients with ulcerative colitis (UC). However, there are conflicting data on impact of early intervention on longer-term adverse events. Therefore, we conducted a systematic review and meta-analysis assessing the impact of early biologic treatment on rates of IBD-related surgery.

METHODS

A systematic search was conducted in April 2022. Studies were included if biologic initiation was compared between patients starting early (<3 years of diagnosis or top-down treatment) vs later (>3 years of diagnosis or step-up treatment). Studies with <1 year of follow-up were excluded. The outcomes were colectomy and CD-related surgery for patients with UC and CD, respectively. Random-effects analyses were conducted to compare rates of IBD surgery between early and late biologic treatment.

RESULTS

Eighteen studies were included in the meta-analysis. Three studies included patients with UC and 15 studies included patients with CD. In patients with CD, early biologic therapy was associated with lower odds of surgery (odds ratio, 0.63; 95% confidence interval, 0.48-0.84) compared with late treatment. Conversely, in patients with UC, the odds of colectomy were increased (odds ratio, 2.86; 95% confidence interval, 1.30-6.30).

CONCLUSIONS

Early biologic treatment is associated with lower rates of surgery in patients with CD. In contrast, early biologic therapy appears to be associated with higher rates of colectomy in patients with UC, which may be confounded by disease severity.

Post-acute phase and sequelae management of epidermal necrolysis: an international, multidisciplinary DELPHI-based consensus

BACKGROUND

Long-term sequelae are frequent and often disabling after epidermal necrolysis (Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)). However, consensus on the modalities of management of these sequelae is lacking.

OBJECTIVES

We conducted an international multicentric DELPHI exercise to establish a multidisciplinary expert consensus to standardize recommendations regarding management of SJS/TEN sequelae.

METHODS

Participants were sent a survey via the online tool "Survey Monkey" consisting of 54 statements organized into 8 topics: general recommendations, professionals involved, skin, oral mucosa and teeth, eyes, genital area, mental health, and allergy workup. Participants evaluated the level of appropriateness of each statement on a scale of 1 (extremely inappropriate) to 9 (extremely appropriate). Results were analyzed according to the RAND/UCLA Appropriateness Method.

RESULTS

Fifty-two healthcare professionals participated. After the first round, a consensus was obtained for 100% of 54 initially proposed statements (disagreement index < 1). Among them, 50 statements were agreed upon as 'appropriate'; four statements were considered 'uncertain', and ultimately finally discarded.

CONCLUSIONS

Our DELPHI-based expert consensus should help guide physicians in conducting a prolonged multidisciplinary follow-up of sequelae in SJS-TEN.

Telehealth-supervised exercise in systemic lupus erythematosus: A pilot study

OBJECTIVES

To explore the feasibility and effectiveness of telehealth-supervised exercise for adults with Systemic lupus erythematosus (SLE).

METHODS

This was a non-randomised controlled pilot trial comparing telehealth-supervised exercise (8 weeks, 2 days/week, 45 min, moderate intensity) plus usual care with usual care alone. Mixed methods were used to assess change in fatigue (FACIT-fatigue), quality of life (SF36), resting fatigue and pain (11-point scale), lower body strength (five-time sit-to-stand) and endurance (30 s sit-to-stand), upper body endurance (30 s arm curl), aerobic capacity (2 min step test), and experience (survey and interviews). Group comparison was performed statistically using a two-sample T-test or Mann-Whitney U-test. Where known, we used MCID or MCII, or assumed a change of 10%, to determine clinically meaningful change within groups over time. Interviews were analysed using reflexive thematic analysis.

RESULTS

Fifteen female adults with SLE were included (control group n = 7, exercise group n = 8). Statistically significant differences between groups, in favour of the exercise intervention, were noted for SF36 domain emotional well-being (p = 0.048) and resting fatigue (p = 0.012). There were clinically meaningful improvements over time for FACIT-fatigue (+6.3 ± 8.3, MCID >5.9), SF36 domains physical role functioning (+30%), emotional role functioning (+55%), energy/fatigue (+26%), emotional well-being (+19%), social functioning (+30%), resting pain (-32%), and upper body endurance (+23%) within the exercise group. Exercise attendance was high (98%, 110/112 sessions); participants strongly agreed (n = 5/7, 71%) or agreed (n = 2/7, 29%) they would do telehealth-supervised exercise again and were satisfied with the experience. Four themes emerged: (1) ease and efficiency of exercising from home, (2) value of live exercise instruction, (3) challenges of exercising at home, and (4) continuation of telehealth-supervised exercise sessions.

CONCLUSION

Key findings from this mixed-method investigation suggest that telehealth-supervised exercise was feasible for, and well-accepted by, adults with SLE and resulted in some modest health improvements. We recommend a follow-up RCT with more SLE participants.

The Need to Prioritize Model-Updating Processes in Clinical Artificial Intelligence (AI) Models: Protocol for a Scoping Review

BACKGROUND

With an increase in the number of artificial intelligence (AI) and machine learning (ML) algorithms available for clinical settings, appropriate model updating and implementation of updates are imperative to ensure applicability, reproducibility, and patient safety.

OBJECTIVE

The objective of this scoping review was to evaluate and assess the model-updating practices of AI and ML clinical models that are used in direct patient-provider clinical decision-making.

METHODS

We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist and the PRISMA-P protocol guidance in addition to a modified CHARMS (Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) checklist to conduct this scoping review. A comprehensive medical literature search of databases, including Embase, MEDLINE, PsycINFO, Cochrane, Scopus, and Web of Science, was conducted to identify AI and ML algorithms that would impact clinical decision-making at the level of direct patient care. Our primary end point is the rate at which model updating is recommended by published algorithms; we will also conduct an assessment of study quality and risk of bias in all publications reviewed. In addition, we will evaluate the rate at which published algorithms include ethnic and gender demographic distribution information in their training data as a secondary end point.

RESULTS

Our initial literature search yielded approximately 13,693 articles, with approximately 7810 articles to consider for full reviews among our team of 7 reviewers. We plan to complete the review process and disseminate the results by spring of 2023.

CONCLUSIONS

Although AI and ML applications in health care have the potential to improve patient care by reducing errors between measurement and model output, currently there exists more hype than hope because of the lack of proper external validation of these models. We expect to find that the AI and ML model-updating methods are proxies for model applicability and generalizability on implementation. Our findings will add to the field by determining the degree to which published models meet the criteria for clinical validity, real-life implementation, and best practices to optimize model development, and in so doing, reduce the overpromise and underachievement of the contemporary model development process.

A review of the vitiligo literature to standardize the expression of disease severity

The literature on vitiligo is extremely heterogeneous with limited standardization in vitiligo disease severity reporting. The IDEOM Vitiligo Workgroup initiated a project to develop an improved understanding of clinical reporting of vitiligo severity and extent. A medical librarian-developed literature review identified 51 English-language clinical trials treating vitiligo topically using topical corticosteroids or topical tacrolimus that included adult and paediatric patients, with 10 or more patients. Grading of studies was performed using SORT criteria. The grading systems used included three studies reporting overall improvement: one as absolute Improvement vs. did not improve (B2), one as marked improvement (C3) and one as improvement, no change or worse (A2). Severity was reported as straight body surface area scoring (BSA) in five trials with grades of (A1, A1, B1, C2 and C3), and two via photography and mapping (A1, A2). Many studies report success as meeting the metric of 50% improvement or clearance (C3). Kanwar et al. further subdivides this into 50% to &lt;75% or &gt;75% (C3). Three studies add the complete clearance metric (A1, A1, B1), with some adding worsening categories. Most studies create a grading system including G0- no change (A1, A1, A2, A2&lt; B2, B2, B3, B3), G1- 1–25%, G2- 26–50%, G3- 51–75%, G4- 75–99% (one study by Lepe et al. reports this as &gt;75%) and G5- 100% re-pigmentation [Bae et al. (C2) report these numbers as 0, 1–24%, 25–49%, 50–74%, 75–99%, 100%]. Variations in response include the meta-analysis by Lee et al. reporting &gt;25%, &gt;50% and &gt;75% re-pigmentation and the combination of G0 and G1 as &lt; or = 25% re-pigmentation, considered a failure (A1, A1, A2. B2, C3, C3, C3). Koopmans-VanDorp (B2) and Kandil (B2) break down re-pigmentation as none, beginning (&lt;25%), good (25–90%) or complete or almost complete (90–100%) or spontaneous re-pigmentation. Success can be defined as G3–G5 or G4–G5. Kathuria classifies &lt;50% as failure (A1). Hu and Farajzadeh (A2) classify &gt;50% as success, Bae (C2) classifies &gt;75% and Kumari (B2) as &gt;90% improvement. Majid further subdivides the score into six subdivisions (A1). Abd-Elazim (A2) reports VASI and Baldo reports DLQI. Sach (C1) and Batchelor (A1) use the vitiligo noticeability scale Baldo, with target patches reported as ‘a lot less noticeable’ or ‘no longer noticeable’ being successful. Ibrahim (A2) uses Patient-Expressed Satisfaction, reporting ‘not satisfied’, ‘slightly satisfied’, ‘satisfied’ or ‘very satisfied’. Batchelor (A1) report percentage re-pigmentation, onset and maintenance of response, treatment burden, QoL, side effects and cost-effectiveness. Body surface area total and quartiles of improvement are the most commonly reported metrics in studies with high-level evidence. The addition of categories of no improvement, complete clearance, spontaneous improvement and worsening appears to enhance information collection. Collection of data using photographs or computer-assisted BSA monitoring enhances data reproducibility. Using 50%, 75% and 90% as thresholds for success appears to be standardized, with a rarer inclusion of 100%. Validated scores like VASI represent a validated alternative collection method, which can be modified to address the 50%, 75% and 90% thresholds. Quality of life has not per se been correlated to clinical response to topical therapeutics, and current scores including patient expression of satisfaction, vitiligo noticeability and satisfaction are not known to reflect topical response at this time.

Vitiligo evidence-based expert consensus recommendations for paediatric and adolescent patients: part I—topical therapeutics

No United States paradigm for the treatment of paediatric, adolescent and young adult vitiligo has been developed. To develop evidence and consensus-based expert opinion to promote therapeutic consistency for the diagnosis and treatment of vitiligo. An IRB-exempted process was developed to produce consensus recommendations based on literature review and SORT criteria. Research questions were reviewed on 9 May 2022 in a video-based conference. Forty-two recommendations were made on the diagnosis of vitiligo (5) and optimal topical therapeutics (37). Topical calcineurin inhibitors, topical corticosteroids and topical ruxolitinib 1·5% cream were all identified as potential first-line therapies in the management of paediatric and adolescent patients with specific guidance on age-based data, frequency of application, minimum length of the therapeutic trial and coordinated usage of ultraviolet light therapy. The literature on paediatric and adolescent vitiligo has a heterogeneous methodology and lack of patient-reported outcomes. Children with vitiligo may be effectively managed with a variety of topical agents as first- and second-line therapy. Evidence supports the utility of topical calcineurin inhibitors, topical corticosteroids and topical JAK inhibitors, with limitations based on factors such as location, body surface area and age.

Family Treatments for Individuals at Risk for Suicide

Background: This PRISMA scoping review explored worldwide research on family-based treatments for suicide prevention. Research on this topic highlights the importance of facilitating familial understanding of a suicidal individual. Aim: The review sought evidence of outcomes of trials in which both the patient and family member in the intervention arm attended the same sessions at which suicide was openly discussed. Method: To explore this topic, the authors searched for randomized and nonrandomized controlled trials using Medline (Ovid), PsycINFO (Ovid), Social Services Abstracts (EBSCO), and Web of Science on July 8, 2020. Results: Ten different studies were included that spanned five treatment modalities. Specifically, of the interventions in these 10 articles, 40% employed some sort of cognitive-behavioral therapy, 20% examined attachment-based family therapy, 20% used family-based crisis intervention, and the remaining 20% were distinct interventions from one another. Additionally, several of these articles demonstrated rigorous study methodology and many of the articles reported significant improvements in suicidal ideation or behaviors. Conclusion: Several important research gaps were identified. While this approach has been largely understudied, and to date has been primarily researched in adolescent populations, family interventions have great potential for treatment and prevention of suicidality.

Postmortem changes in brain cell structure: a review

Brain cell structure is a key determinant of neural function that is frequently altered in neurobiological disorders. Following the global loss of blood flow to the brain that initiates the postmortem interval (PMI), cells rapidly become depleted of energy and begin to decompose. To ensure that our methods for studying the brain using autopsy tissue are robust and reproducible, there is a critical need to delineate the expected changes in brain cell morphometry during the PMI. We searched multiple databases to identify studies measuring the effects of PMI on the morphometry (i.e. external dimensions) of brain cells. We screened 2119 abstracts, 361 full texts, and included 172 studies. Mechanistically, fluid shifts causing cell volume alterations and vacuolization are an early event in the PMI, while the loss of the ability to visualize cell membranes altogether is a later event. Decomposition rates are highly heterogenous and depend on the methods for visualization, the structural feature of interest, and modifying variables such as the storage temperature or the species. Geometrically, deformations of cell membranes are common early events that initiate within minutes. On the other hand, topological relationships between cellular features appear to remain intact for more extended periods. Taken together, there is an uncertain period of time, usually ranging from several hours to several days, over which cell membrane structure is progressively lost. This review may be helpful for investigators studying human postmortem brain tissue, wherein the PMI is an unavoidable aspect of the research.

Theoretical model of recovery following a suicidal episode (COURAGE): scoping review and narrative synthesis

BACKGROUND

Despite a significant need, there are currently no rigorously developed empirically based models for what personal recovery from a suicidal episode looks like.

AIMS

To develop a theoretical model of personal recovery after a suicidal episode, based on a comprehensive literature review and stakeholder feedback.

METHOD

A scoping review of all empirical studies on this topic was conducted, followed by a thematic analysis to create a preliminary framework. Consultation-based revisions were then made based on feedback from a stakeholder panel to develop the final theoretical model.

RESULTS

The final model comprised seven themes: choosing life, optimising identity, understanding oneself, rediscovering meaning, acceptance, growing connectedness and empowerment (acronym 'COURAGE'). Although there are some similarities between COURAGE and other models of personal recovery, there are components, such as 'choosing life' and 'understanding oneself', that are specific to recovery after an acute suicidal episode.

CONCLUSIONS

To our knowledge, this is the first study to use a comprehensive literature review with stakeholder feedback to develop a conceptual model of personal recovery after an acute suicidal episode. This model has important implications for both researchers and clinicians to consider. Looking ahead, COURAGE can inform the reconceptualisation of assessment, research and clinical care of individuals who have experienced a suicidal episode.

89 DIAGNOSIS AND TREATMENT OF SUSPECTED OBSTRUCTIVE SLEEP APNOEA (OSA) IN OLDER PEOPLE: A RETROSPECTIVE COMPARATIVE ANALYSIS

Background

Obstructive Sleep Apnoea (OSA) is common yet often undiagnosed in older people as symptoms of fatigue and poor sleep are common and non-specific. OSA screening tools also lack validity in older patients. This study aims to review the clinical presentation, use of screening tools and treatment adherence in older people.

Methods

A retrospective cohort study of patients &gt;65 years attending a tertiary sleep clinic who underwent polysomnography for suspected OSA was performed. Electronic patient records were reviewed to obtain information on clinical presentation, screening scores, polysomnography reports and treatment initiated. Correlation between variables was performed using Pearson’s correlation co-efficient and represented using R-score. To compare CPAP usage with younger people, a cohort of controls &lt;65 years were matched in 2:1 ratio for OSA severity (mild, moderate or severe) at diagnosis. Comparison of adherence rates was performed using Mann-Whitney U-test and represented using Z-scores.

Results

A convenience sample of 100 consecutive older patients were included. Fatigue was present in 53% and witness reported snoring in 86% and apnoeas in 56%. Moderate or severe OSA was confirmed by polysomnography in 91% cases. BMI and the STOP-BANG questionnaire were positively correlated with OSA severity as measured by Apnoea Hypopnea Index, while ESS and Berlin Questionnaire were not. Positive pressure ventilation was initiated in 90% patients. CPAP was extremely effective with the median AHI falling to within normal range on follow up. CPAP usage was significantly higher in older patients compared with younger matched control (85% vs 66% p=013).

Conclusion

Older people with OSA present with classical symptoms. STOP -BANG questionnaire and BMI were positively correlated with AHI values while other screening tools lacked validity. Treatment with CPAP was highly efficacious in older people with high usage rates and should be considered as first-line treatment for moderate and severe OSA in older patients.

293 PRE-ADMISSION POTENTIALLY INAPPROPRIATE PRESCRIBING PREVALENCE ON A CARE OF THE OLDER ADULT MEDICAL WARD

Background

Potentially Inappropriate Prescribing (PIP) is a common but critical issue in care of the older adult. It is estimated that between 50 and 70% of those over 65 years are receiving at least one potentially inappropriate medication. Polypharmacy is a good indicator of PIP as it can indicate over- and inappropriate prescribing through prescribing cascade, exposing patients to risks of drug interactions and Adverse Drug Events (ADEs). 10-20% of hospital admissions of older adults are directly related to ADE of inappropriately prescribed drugs.

Methods

Point prevalence study using the ‘Screening Tool of Older Persons Prescriptions’ (STOPP) to identify PIPs on a geriatric medicine ward. Patients over 65 years of age admitted from home were included in the study. Patients’ pre-admission medications and changes made to these were assessed using STOPP.

Results

Sixteen patients out of 22 met the inclusion criteria. The average age of the patients included in the study was 82.3 years with a range from 70 to 88 years. 75% were female. 94% had polypharmacy prior to admission with an average of 2.25 PIPs (range 0 to 5). 43% (n=7) had all their PIPs addressed by a geriatrician as per STOPP, with a further 18% (n=3) having some of their PIPs altered. 25% (n=4) did not have any alterations to their PIPs.

Conclusion

Despite widely known impacts of PIPs on older adults, PIP remains highly prevalent in those admitted to hospital. PIP and polypharmacy can increase incident frailty two-fold and polypharmacy and frailty can lead to a 6-fold increase in mortality within two and a half years. We must actively educate all those involved in prescribing for this cohort of patients to reduce PIPs and their adverse effects.

250 AUDIT INTO THE USE AND COMPLICATIONS OF MAINTENANCE INHALER THERAPY IN MEDICALLY ADMITTED PATIENTS OVER THE AGE OF 65 YEARS

Background

Adequate maintenance inhaler use is associated with improved symptom control and reduced exacerbation rates, however, cognitive impairment and limitations in dexterity can be a barrier to inhaled therapy.

Methods

Between the 20th of April and 30th May 2022 patients admitted to our ward over the age of 65 years had their maintenance inhaler technique assessed using the National Asthma Council of Australia checklist. Symptom control was assessed by either the Asthma Control Test (ACT) or the Chronic Obstructive Pulmonary Disease (COPD) assessment tool (CAT). The 4 AT score was used to screen for neurocognitive impairment.

Results

20 patients were recruited to the study. 40% were male. Mean age 81.5 years +- 6.8years. The respiratory diagnosis was COPD in 70%, Asthma 20%, Interstitial Lung Disease 5% and bronchiectasis 5%. 65 % had pulmonary function testing performed. Asthma symptom control was within target in 75% of the asthma patients (ACT score &gt;20). Mean score 21 +- 2.5. COPD symptom control was within target in 31% of patients (CAT score &lt;10) . Mean CAT score of 19.3 +- 8. 4. 20% had a pre-admission diagnosis of neurocognitive impairment. The mean 4AT score of the cohort was 1.2. 35% had audible wheeze at the time of review. 80% of inhalers were prescribed for the licensed indication. 35% had potential complications of inhaler therapy – 25% pneumonia and 10% oral candidiasis. Notably all pneumonias were associated with fluticasone. Inhaler technique was associated with errors in almost a quarter of all patients (24%). Increasing 4AT score correlated with high likelihood of inhaler errors, R = 0.63.

Conclusion

Poor inhaler technique is correlated with neurocognitive impairment. Pneumonia is a potential complication of inhaler therapy and represents an opportunity for deprescribing in patients with COPD.

Suicide and Telehealth Treatments: A PRISMA Scoping Review

BACKGROUND

This PRISMA scoping review explored worldwide research on the delivery of suicide-specific interventions through an exclusive telehealth modality. Research over telehealth modalities with suicidal individuals highlights the importance of facilitating participants' access to treatments despite location and circumstances (e.g., rural, expenses related to appointments, etc.).

AIM

The review sought evidence of outcomes of trials or projects in which both the patient and therapist attended sessions conjointly and openly discussed suicide over a telehealth modality (e.g., phone, zoom).

METHOD

To explore this topic the authors searched for research trials and quality improvement projects using Ovid Medline, Ovid Embase, Ovid PsycINFO, EBSCO Social Services Abstracts, and Web of Science on 3/3/2021.

RESULTS

Nine different articles were included that each spanned distinct treatments, with eight being research studies and one being a quality improvement project.

LIMITATIONS

Publications featuring ongoing or upcoming research in which complete study results were not available did not meet inclusion criteria for this review.

CONCLUSION

Several important research gaps were identified. While this approach has been largely understudied, exclusive telehealth delivery of suicide-specific interventions has great potential for the prevention of suicidality, especially in the era of COVID-19 and beyond.

Prenatal ambient temperature and risk for schizophrenia

OBJECTIVE

We conducted a systematic review of the published literature to test the hypothesis that maternal exposure to extremes of ambient temperatures during pregnancy is associated with the risk for psychiatric disorders or congenital malformations in offspring, both of which are indicative of perturbations of fetal neurodevelopment.

METHOD

This study was conducted in accordance with the recommendations outlined in the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting proposal. Electronic databases (Ovid MEDLINE, Ovid Embase, Ovid PsycINFO, Ovid Global Health, Web of Science, and Cochrane Library) were searched. Four independent reviewers selected studies with the following criteria: (1) prenatal maternal ambient temperature exposure; (2) outcome of offspring psychiatric disorder or congenital defects; (3) empirical study; (4) full-length article, no conference presentations or abstracts.

RESULTS

Twenty-two studies met criteria and one was added from a reference list (n = 23). Of these, schizophrenia (n = 5), anorexia nervosa (n = 3) and congenital cardiovascular malformations (n = 6) studies were the most common. Each of these categories showed some evidence of association with an early pregnancy maternal ambient heat exposure effect, with other evidence for a late pregnancy cold effect.

CONCLUSION

Some evidence supports a role for early pregnancy maternal exposure to extreme ambient heat in the development of psychiatric disorders, but large-scale, prospective cohort data on individual births is essential. Optimal studies will be conducted in seasonally variable climates, accounting for actual maternal residence over the pregnancy and at parturition, local environmental temperature records, and appropriate covariates, similar to studies identified by this systematic review for congenital malformations.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run

We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2  M_{⊙} and 1.0  M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14  yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200]  Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2  M_{⊙}<m_{PBH}<1.0  M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1  M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Total neoadjuvant chemotherapy: a silver lining during the COVID pandemic for a patient with locally advanced diffuse distal gastric adenocarcinoma

Perioperative oncological therapies resulting in pathological complete response (pCR) in diffuse-type distal gastric adenocarcinoma are extremely rare. We report a case of locally advanced (cT3 N2 M0) diffuse-type distal gastric adenocarcinoma treated with 'total neoadjuvant' FLOT (eight cycles), due to the COVID-19 pandemic, and laparoscopic radical subtotal gastrectomy with D2 lymphadenectomy. The patient demonstrated a progressive radiological response on positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro-d-glucose integrated with computed tomography (¹⁸F-FDG PET-CT) and pCR in the resected specimen (ypT0 N0). As far as we are aware, this is the first case of pCR in locally advanced T3 N2 diffuse distal gastric cancer to be reported in the literature. It introduces a novel approach of total neoadjuvant chemotherapy with ¹⁸F-FDG PET-CT to assess response, combined with radical minimally invasive surgical management to provide optimal care for patients with gastric cancer.

Risk factors for local atypical fibroxanthoma recurrence and progression to pleomorphic dermal sarcoma: A meta-analysis of individualized participant data

Background

Risk factors for local atypical fibroxanthoma (AFX) recurrence and progression to pleomorphic dermal sarcoma (PDS) have not previously been identified.

Objective

To identify risk factors and provide follow‐up suggestions for local AFX recurrence and progression to PDS.

Methods and Materials

A literature search was performed in the PubMed, EMBASE, and Cochrane databases. The PRISMA and MOOSE guidelines were followed. The risks of local AFX recurrence and progression to PDS were presented as Kaplan–Meier plots and risk factors were presented as hazard ratios (HRs) calculated with univariate and multivariate Cox regression.

Results

Five hundred and ninety‐eight patients with AFX from 14 studies were included. Age >74 years and male sex significantly increased the risk of local recurrence (HR: 7.31 [95% confidence interval [CI]: 1.78–30.0], p < 0.01 and HR: 2.89 [95% CI: 1.04–8.01], p < 0.05, respectively). There was no difference when comparing wide local excision and Mohs' micrographic surgery (p = 0.89). The risks of local AFX recurrence and progression to PDS after 2 years were <1%.

Conclusion

A more intensive follow‐up regimen could be considered in patients >74 years old and males due to the higher risk of local AFX recurrence.

Systematic Review with Meta-Analysis: Fecal Microbiota Transplantation for Severe or Fulminant Clostridioides difficile

BACKGROUND

Severe and fulminant Clostridioides difficile infection (CDI) is associated with significant morbidity and mortality. While fecal microbiota transplantation (FMT) has proved to be a highly effective treatment for recurrent CDI, its efficacy in severe or fulminant CDI remains uncertain.

AIMS

To perform a systematic review with meta-analysis evaluating clinical outcomes and safety of FMT in severe and fulminant CDI.

METHODS

A systemic review with meta-analysis was performed through comprehensive search of Embase, Medline (Ovid), trial registers, and conference abstracts through January 2020. Studies on FMT in severe and fulminant CDI were included. Meta-analysis was done with random effects models given heterogeneity to estimate rates of cure, mortality, and colectomy. Publication bias was assessed using Egger's test.

RESULTS

Sixteen studies comprised of one randomized controlled trial, four cohort studies, and eleven case series were analyzed. In total, 676 patients underwent FMT for severe or fulminant CDI. The overall rate of clinical cure after single FMT was 61.3% (95% CI 43.2-78.0%) with 10.9% (95% CI 0.2-30.2%) of patients experiencing major adverse events. The overall pooled colectomy rate after FMT was 8.2% (95% CI 0.1-23.7%) with a pooled all-cause mortality rate after FMT of 15.6% (95% CI 7.8-25.0%).

CONCLUSION

Low-quality data support the use of fecal microbiota transplantation in patients with severe and fulminant Clostridioides difficile infection.

A cross-sectional analysis of psychological distress among higher education students in Ireland

OBJECTIVES

To examine levels of psychological distress among higher education students in Ireland overall and across a range of personal, higher education, and socioeconomic characteristics, prior to the COVID-19 pandemic.

METHODS

A cross-sectional online survey of college students in Ireland was undertaken in 2018. Data on 5201 students from 13 higher education institutions (HEIs) were analyzed. Stress, anxiety, and depression symptom scores based on the Depression, Anxiety and Stress Scale (DASS-21) were calculated and reported, with statistical testing used to compare across groups.

RESULTS

Overall, 29.6% and 19.1% of respondents were classified in the mild to moderate and severe to extremely severe range for depression respectively. The corresponding proportions were 25.9% and 20.7% for anxiety, and 24.5% and 14.8% for stress. Differences across groups included higher levels of psychological distress for transgender and female students compared to males (p < 0.01), for gay/lesbian/bisexual students compared to heterosexuals (p < 0.01), for undergraduates compared to postgraduates (p < 0.01), for students from intermediate/technical/service/unskilled social classes compared to professional/self-employed social classes (p < 0.01), and for those with financial difficulties compared to those without financial difficulties (p < 0.01).

CONCLUSIONS

Rates of psychological distress were high amongst college students in Ireland prior to the COVID-19 pandemic, with substantial differences across groups. Due to study limitations, such as possible selection bias, the findings need replication. Further research is needed to determine the impact of the pandemic on the prevalence of mental illness in this population.

Demonstrating the processes and outcomes of a rural Community Mental Health Rehabilitation Service: A realist evaluation

BACKGROUND

As part of significant mental health reform, the Community Mental Health Rehabilitation Service (CMHRS) was implemented in rural South Australia. The CMHRS is a 10-bed mental health residential program offering rehabilitative mental health support to rural residents.

AIM

To analyse the CMHRS service delivery model and its impact on recovery outcomes for consumers.

METHODS

A mixed method, realist evaluation approach was utilised. A purposive sample of CMHRS staff (n = 6) and consumers (n = 8) were recruited. Consumer recovery was measured using the RAS-DS (on admission and discharge). Participants' perspectives of the service were gained via one staff focus group (n = 6) and individual semi-structured interviews (consumers n = 6; staff n = 2). Pre-post RAS-DS scores were analysed using paired t-tests/Wilcoxon paired-signed rank test, with qualitative data analysed thematically.

RESULTS

Significant positive increases in RAS-DS total scores were observed at discharge, supported by the qualitative themes of (re)building relationships and social connections and recovering health and wellbeing. Contextual factors (e.g. staffing) and program mechanisms (e.g. scheduling) impacting on service implementation were identified.

CONCLUSION

Maintaining a rehabilitation recovery-focused approach, balanced with an appropriately trained multi-disciplinary team, are vital for maximising positive consumer outcomes.

SIGNIFICANCE

This realist evaluation identifies critical factors impacting rural mental health rehabilitation service delivery.

Association between social deprivation status, age of presentation, and survival following ST-segment elevation myocardial infarction

Introduction

Many factors influence age of presentation with and survival following ST-segment myocardial infarction (STEMI). These include age, mode of, and time-delay to emergency treatment, diabetes and smoking. We sought to assess whether overall social deprivation status is associated with age of presentation and mortality following STEMI patients treated with primary PCI.

Methods

All patients treated emergently for STEMI in a large Northern Irish tertiary hospital from 2013 – 2017 were reviewed. Social deprivation is determined as a composite score relating to income, crime etc, and assigned to small geographical regions by the Northern Ireland Statistics and Research Agency. Deprivation score was assigned to patients based on their postcode. The database was ranked by social deprivation score and divided in to quintiles. The most (Grp 1) and least (Grp 5) deprived quintiles were compared. Mortality was determined from a national electronic health record.

Results

1,192 patients were included in the analysis. Mean follow up was 52.5 months (SD 15.6), minimum follow up was 35.6 months. There was no difference in gender: 70.1% male in Grp 1 vs 75.2% male in Grp 5 (p=0.68); no difference in ECG to balloon time: mean 89.9mins (95% CI 84.9–94.9) Grp 1 vs 90.5mins (95% CI 86.2–94.9) Grp 5 (p=0.86). The more deprived group was younger: mean age 60.6 (95% CI 59.5–61.6) vs 65.2 (95% CI 64.2–66.3) (p&lt;0.000). Crude survival measured by Log-rank test was the same between the groups (p=0.52). Following Cox-regression adjustment for age, survival was longer in the least deprived group (p=0.042).

Conclusion

Social deprivation is associated with both a younger age of presentation with, and a higher mortality following STEMI. This is important variable is often overlooked in medical literature and should be further studied.

Group treatments for individuals at risk for suicide: A PRISMA scoping review (ScR)

BACKGROUND

This PRISMA scoping review explored worldwide research of interventions for suicide prevention delivered within a group setting. Research on group treatments underscores the importance of peer connection in diminishing social isolation and increasing social support. Additional benefits of group treatment include cost efficiency and maximization of staff time. However, the clinical outcomes of group treatments with individuals at risk for suicide are less understood and under researched.

AIM

This scoping review had two objectives: 1) To identify existing group treatments where suicidal thoughts and behaviors are openly discussed; 2) To examine the outcomes of these identified treatments, with special attention to treatment integrity.

METHOD

To address these aims the authors searched Medline (Ovid), Embase (Ovid), and PsycINFO (Ovid), on November 25, 2020. At the Full Text stage, articles were included that were peer reviewed, described a suicide specific group intervention and reported suicide specific outcomes. An additional requirement was open dialogue of suicide in the group intervention.

RESULTS

Only ten research reports of suicide-specific group treatments were identified in our PRISMA-ScR. In spite of many differences in setting, population, length, and frequency of sessions, all ten groups reported improvements in varying aspects of suicide symptoms. The only adverse impacts were reported by two studies wherein two (of 92) participants attempted suicide and a small number (7%) of adolescents reported feeling triggered with suicidal thinking during a session. Despite our focus on empirical data in this review, the methodological rigor of the studies evaluated was limited.

CONCLUSION

Despite the paucity of group treatment research in which suicidal thoughts and behaviors are openly discussed, the outcomes of these treatments were promising in decreasing suicide risk. These results may be due to unfounded fears of contagion. Further implications of these findings are considered along with limitations that may have excluded clinical work from meeting inclusion criteria for this review. Nonetheless, this evidence suggests that, suicide-focused groups have great potential for prevention of suicidal symptoms and should be further expanded in the future.

Prevalence and Progression of Incidental Terminal Ileitis on Non-diagnostic Colonoscopy: A Systematic Review and Meta-analysis

BACKGROUND

Incidentally diagnosed terminal ileitis [IDTI] has been reported among asymptomatic persons undergoing non-diagnostic colonoscopy. The purpose of our study was to determine the prevalence and long-term outcomes of asymptomatic terminal ileitis.

METHODS

We performed a systematic review using three biomedical databases [Medline, Embase, and Web of Science] and relevant scientific meeting abstracts. We identified observational studies that reported the prevalence of IDTI in adults undergoing screening or polyp surveillance colonoscopy and/or the long-term outcomes of such lesions. A random-effects meta-analysis was conducted to determine the pooled prevalence rate of IDTI. The progression of IDTI to overt Crohn's disease [CD] was also described.

RESULTS

Of 2388 eligible studies, 1784 were screened after excluding duplicates, 84 were reviewed in full text, and 14 studies were eligible for inclusion. Seven studies reported the prevalence of IDTI in 44 398 persons undergoing non-diagnostic colonoscopy, six studies reported follow-up data, and one study reported both types of data. The pooled prevalence rate of IDTI was 1.6% (95% confidence interval [CI] 0.1-21.8%) with significant heterogeneity [I2 = 99.7]. Among patients who had undergone non-diagnostic colonoscopy and had follow-up data [range 13-84 months reported in five studies], progression to overt CD was rare.

CONCLUSIONS

IDTI is not uncommon on non-diagnostic colonoscopies. Based on limited data, the rate of its progression to overt CD seems low, and watchful waiting is likely a reasonable strategy. Further long-term follow-up studies are needed to inform the natural history of incidental terminal ileitis, factors that predict progression to CD, and therapeutic implications.
