Applying Sydney Triage to Admission Risk Tool (START) to improve patient flow in emergency departments: a multicentre randomised, implementation study.

BACKGROUND: To determine the effectiveness of applying the Sydney Triage to Admission Risk Tool (START) in conjunction with senior early assessment in different Emergency Departments (EDs). METHODS: This multicentre implementation study, conducted in two metropolitan EDs, used a convenience sample of ED patients. Patients who were admitted, after presenting to both EDs, and were assessed using the existing senior ED clinician assessment, were included in the study. Patients in the intervention group were assessed with the assistance of START, while patients in the control group were assessed without the assistance of START. Outcomes measured were ED length of stay and proportion of patients correctly identified as an in-patient admission by START. RESULTS: A total of 773 patients were evaluated using the START tool at triage across both sites (Intervention group n = 355 and control group n = 418 patients). The proportion of patients meeting the 4-hour length of stay thresholds was similar between the intervention and control groups (30.1% vs. 28.2%; p = 0.62). The intervention group was associated with a reduced ED length of stay when compared to the control group (351 min, interquartile range (IQR) 221.0-565.0 min versus 383 min, IQR 229.25-580.0 min; p = 0.85). When stratified into admitted and discharged patients, similar results were seen. CONCLUSION: In this extension of the START model of care implementation study in two metropolitan EDs, START, when used in conjunction with senior early assessment was associated with some reduced ED length of stay.

Peroral endoscopic myotomy: 10-year outcomes from a large, single-center U.S. series with high follow-up completion and comprehensive analysis of long-term efficacy, safety, objective GERD, and endoscopic functional luminal assessment.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) is becoming the treatment of choice for achalasia. Data beyond 3 years are emerging but are limited. We herein report our 10-year experience, focusing on long-term efficacy and safety including the prevalence, management, and sequelae of postoperative reflux. METHODS: This was a single-center prospective cohort study. RESULTS: Six hundred ten consecutive patients received POEM from October 2009 to October 2019, 160 for type 1 achalasia (26.2%), 307 for type II (50.3%), 93 for type III (15.6%), 25 for untyped achalasia (4.1%), and 23 for nonachalasia disorders (3.8%). Two hundred ninety-two patients (47.9%) had prior treatment(s). There was no aborted POEM. Median operation time was 54 minutes. Accidental mucosotomies occurred in 64 patients (10.5%) and clinically significant adverse events in 21 patients (3.4%). No adverse events led to death, surgery, interventional radiology interventions/drains, or altered functional status. At a median follow-up of 30 months, 29 failures occurred, defined as postoperative Eckardt score >3 or need for additional treatment. The Kaplan-Meier clinical success estimates at years 1, 2, 3, 4, 5, 6, and 7 were 98%, 96%, 96%, 94%, 92%, 91%, and 91%, respectively. These are highly accurate estimates because only 13 patients (2%) were missing follow-up assessments. One hundred twenty-five patients (20.5%) had reflux symptoms more than once per week. At a median of 4 months, the pH study was completed in 406 patients (66.6%) and was positive in 232 (57.1%), and endoscopy was completed in 438 patients (71.8%) and showed reflux esophagitis in 218 (49.8%), mostly mild. CONCLUSIONS: POEM is exceptionally safe and highly effective on long-term follow-up, with >90% clinical success at ≥5 years.

Persistent symptoms after Covid-19: qualitative study of 114 "long Covid" patients and draft quality principles for services.

BACKGROUND: Approximately 10% of patients with Covid-19 experience symptoms beyond 3-4 weeks. Patients call this "long Covid". We sought to document such patients' lived experience, including accessing and receiving healthcare and ideas for improving services. METHODS: We held 55 individual interviews and 8 focus groups (n = 59) with people recruited from UK-based long Covid patient support groups, social media and snowballing. We restricted some focus groups to health professionals since they had already self-organised into online communities. Participants were invited to tell their stories and comment on others' stories. Data were audiotaped, transcribed, anonymised and coded using NVIVO. Analysis incorporated sociological theories of illness, healing, peer support, clinical relationships, access, and service redesign. RESULTS: Of 114 participants aged 27-73 years, 80 were female. Eighty-four were White British, 13 Asian, 8 White Other, 5 Black, and 4 mixed ethnicity. Thirty-two were doctors and 19 other health professionals. Thirty-one had attended hospital, of whom 8 had been admitted. Analysis revealed a confusing illness with many, varied and often relapsing-remitting symptoms and uncertain prognosis; a heavy sense of loss and stigma; difficulty accessing and navigating services; difficulty being taken seriously and achieving a diagnosis; disjointed and siloed care (including inability to access specialist services); variation in standards (e.g. inconsistent criteria for seeing, investigating and referring patients); variable quality of the therapeutic relationship (some participants felt well supported while others felt "fobbed off"); and possible critical events (e.g. deterioration after being unable to access services). Emotionally significant aspects of participants' experiences informed ideas for improving services. CONCLUSION: Suggested quality principles for a long Covid service include ensuring access to care, reducing burden of illness, taking clinical responsibility and providing continuity of care, multi-disciplinary rehabilitation, evidence-based investigation and management, and further development of the knowledge base and clinical services. TRIAL REGISTRATION: NCT04435041.

Per-oral endoscopic myotomy in patients with or without prior Heller's myotomy: comparing long-term outcomes in a large U.S. single-center cohort (with videos).

BACKGROUND AND AIMS: Heller's myotomy (HM) is one of the most effective treatments for esophageal achalasia. However, failures do exist, and the success rate tends to decrease with time. The efficacy of rescue treatments for patients with failed HM is limited. A few small-scale studies have reported outcomes of per-oral endoscopic myotomy (POEM) in these patients. We conducted this study to systematically assess feasibility, safety, and efficacy of POEM on patients who have had HM. METHODS: Patients at least 3 months out from POEM were selected from our prospective database: 318 consecutive POEMs performed from October 2009 to October 2016. The efficacy and safety of POEM were compared between the 46 patients with prior HM and the remaining 272 patients. RESULTS: Patients with prior HM had longer disease history, more advanced disease, more type I and less type II achalasia, lower before-POEM Eckardt scores, and lower before-POEM lower esophageal sphincter (LES) pressure (all P < .01). Procedure parameters and follow-up results (clinical success rate, Eckardt score, LES pressure, GERD score, esophagitis, and pH testing) showed no significant difference between the 2 groups. For the 46 HM-POEM patients, no clinically significant perioperative adverse events occurred. Their overall clinical success rate (Eckardt score ≤3 and no other treatment needed) was 95.7% at a median follow-up of 28 months. CONCLUSION: POEM as a rescue treatment for patients with achalasia who failed HM is feasible, safe, and highly effective. It should be the treatment of choice in managing these challenging cases at centers with a high level of experience with POEM.

Preparing for Disaster: a Cross-Sectional Study of Social Connection and Gun Violence.

Living in communities with persistent gun violence is associated with negative social, behavioral, and health outcomes, analogous to those of a natural disaster. Taking a disaster-preparedness approach may identify targets for community-based action to respond to on-going gun violence. We assessed the relevance of adapting a disaster-preparedness approach to gun violence and, specifically, the relationship between perceived collective efficacy, its subscales of social cohesion and informal social control, and exposure to gun violence. In 2014, we conducted a cross-sectional study using a community-based participatory research approach in two neighborhoods in New Haven, CT, with high violent crime rates. Participants were ≥18 years of age and English speaking. We measured exposure to gun violence by adapting the Project on Human Development in Chicago Neighborhoods Exposure to Violence Scale. We examined the association between perceived collective efficacy, measured by the Sampson Collective Efficacy Scale, and exposure to gun violence using multivariate modeling. We obtained 153 surveys (51% response rate, 14% refusal rate, and 35% non-response rate). Ninety-five percent reported hearing gunfire, 58% had friend or family member killed by gun violence, and 33% were physically present during a shooting. In the fully adjusted model, one standard deviation higher perceived collective efficacy was associated with lower reported exposure to gun violence (ß = -0.91, p < 0.001). We demonstrated that it is possible to activate community members and local officials to engage in gun violence research. A novel, community-based approach adapted from disaster-preparedness literature may be an effective framework for mitigating exposure to gun violence in communities with persistent gun violence.

Breast Milk Protects Against Gastrointestinal Symptoms in Infants at High Risk for Autism During Early Development.

OBJECTIVES: Parents of children with autism spectrum disorders (ASDs) often report gastrointestinal (GI) dysfunction in their children. The objectives of the present study were to determine whether infants at high risk for developing ASD (ie, siblings of children diagnosed as having ASD) show greater prevalence of GI problems and whether this prevalence is associated with diet and age at weaning from breast milk. METHODS: Using questionnaires, diet history and GI problems were tracked prospectively and retrospectively in 57 high-risk infants and for comparison in 114 low-risk infants (infants from families without ASD history). RESULTS: In low-risk infants, prevalence of GI symptoms, in aggregate, did not vary with diet or age of weaning. By contrast, high-risk infants with GI symptoms were weaned earlier than those without symptoms (P < 0.04), and high-risk infants showed greater prevalence of GI symptoms, in aggregate, on a no breast milk diet than on an exclusive breast milk diet (P < 0.017). Constipation, in particular, was more prevalent in high-risk infants compared with low-risk infants (P = 0.01), especially on a no breast milk diet (P = 0.002). High-risk infants who completed weaning earlier than 6 months showed greater prevalence of constipation (P = 0.001) and abdominal distress (P = 0.004) than those fully weaned after 6 months. CONCLUSIONS: The greater prevalence of GI symptoms in high-risk infants suggests that GI dysfunction during early infant development may be a part of the ASD endophenotype. Late weaning and exclusive breast milk were associated with protection against GI symptoms in high-risk infants.

Effect of digestion and storage of human milk on free fatty acid concentration and cytotoxicity.

OBJECTIVES: Fat is digested in the intestine into free fatty acids (FFAs), which are detergents and therefore toxic to cells at micromolar concentration. The mucosal barrier protects cells in the adult intestine, but this barrier may not be fully developed in premature infants. Lipase-digested infant formula, but not fresh human milk, has elevated FFAs and is cytotoxic to intestinal cells, and therefore could contribute to intestinal injury in necrotizing enterocolitis (NEC), but even infants exclusively fed breast milk may develop NEC. Our objective was to determine whether stored milk and milk from donor milk (DM) banks could also become cytotoxic, especially after digestion. METHODS: We exposed cultured rat intestinal epithelial cells or human neutrophils to DM and milk collected fresh and stored at 4°C or -20°C for up to 12 weeks and then treated for 2 hours (37°C) with 0.1 or 1 mg/mL pancreatic lipase and/or trypsin and chymotrypsin. RESULTS: DM and milk stored 3 days (at 4°C or -20°C) and then digested were cytotoxic. Storage at -20°C for 8 and 12 weeks resulted in an additional increase in cytotoxicity. Protease digestion decreased, but did not eliminate cell death. CONCLUSIONS: Present storage practices may allow milk to become cytotoxic and contribute to intestinal damage in NEC.

Digested formula but not digested fresh human milk causes death of intestinal cells in vitro: implications for necrotizing enterocolitis.

BACKGROUND: Premature infants fed formula are more likely to develop necrotizing enterocolitis (NEC) than those who are breastfed, but the mechanisms of intestinal necrosis in NEC and protection by breast milk are unknown. We hypothesized that after lipase digestion, formula, but not fresh breast milk, contains levels of unbound free fatty acids (FFAs) that are cytotoxic to intestinal cells. METHODS: We digested multiple term and preterm infant formulas or human milk with pancreatic lipase, proteases (trypsin and chymotrypsin), lipase + proteases, or luminal fluid from a rat small intestine and tested FFA levels and cytotoxicity in vitro on intestinal epithelial cells, endothelial cells, and neutrophils. RESULTS: Lipase digestion of formula, but not milk, caused significant death of neutrophils (ranging from 47 to 99% with formulas vs. 6% with milk) with similar results in endothelial and epithelial cells. FFAs were significantly elevated in digested formula vs. milk and death from formula was significantly decreased with lipase inhibitor pretreatment, or treatments to bind FFAs. Protease digestion significantly increased FFA binding capacity of formula and milk but only enough to decrease cytotoxicity from milk. CONCLUSION: FFA-induced cytotoxicity may contribute to the pathogenesis of NEC.

Developing services for long COVID: lessons from a study of wounded healers.

Persistent symptoms lasting longer than 3 weeks are thought to affect 10-20% of patients following SARS-CoV-2 infection. No formal guidelines exist in the UK for treating patients with long COVID and services are sporadic and variable, although additional funding is promised for their development.In this study, narrative interviews and focus groups are used to explore the lived experience of 43 healthcare professionals with long COVID. These individuals see the healthcare system from both professional and patient perspectives, thus represent an important wealth of expertise to inform service design.We present a set of co-designed quality standards, highlighting equity and ease of access, minimal patient care burden, clinical responsibility, a multidisciplinary and evidence-based approach, and patient involvement; and we apply these to propose a potential care pathway model that could be adapted and translated to improve care of patients long COVID.

Recommendations for the recognition, diagnosis, and management of long COVID: a Delphi study.

BACKGROUND: In the absence of research into therapies and care pathways for long COVID, guidance based on 'emerging experience' is needed. AIM: To provide a rapid expert guide for GPs and long COVID clinical services. DESIGN AND SETTING: A Delphi study was conducted with a panel of primary and secondary care doctors. METHOD: Recommendations were generated relating to the investigation and management of long COVID. These were distributed online to a panel of UK doctors (any specialty) with an interest in, lived experience of, and/or experience treating long COVID. Over two rounds of Delphi testing, panellists indicated their agreement with each recommendation (using a five-point Likert scale) and provided comments. Recommendations eliciting a response of 'strongly agree', 'agree', or 'neither agree nor disagree' from 90% or more of responders were taken as showing consensus. RESULTS: Thirty-three clinicians representing 14 specialties reached consensus on 35 recommendations. Chiefly, GPs should consider long COVID in the presence of a wide range of presenting features (not limited to fatigue and breathlessness) and exclude differential diagnoses where appropriate. Detailed history and examination with baseline investigations should be conducted in primary care. Indications for further investigation and specific therapies (for myocarditis, postural tachycardia syndrome, mast cell disorder) include hypoxia/desaturation, chest pain, palpitations, and histamine-related symptoms. Rehabilitation should be individualised, with careful activity pacing (to avoid relapse) and multidisciplinary support. CONCLUSION: Long COVID clinics should operate as part of an integrated care system, with GPs playing a key role in the multidisciplinary team. Holistic care pathways, investigation of specific complications, management of potential symptom clusters, and tailored rehabilitation are needed.

Long Covid - The illness narratives.

Callard and Perego depict long Covid as the first illness to be defined by patients who came together on social media. Responding to their call to address why patients were so effective in making long Covid visible and igniting action to improve its care, we use narrative inquiry - a field of research that investigates the place and power of stories and storytelling. We analyse a large dataset of narrative interviews and focus groups with 114 people with long Covid (45 of whom were healthcare professionals) from the United Kingdom, drawing on socio-narratology (Frank), therapeutic emplotment (Mattingly) and polyphonia (Bakhtin). We describe how storytelling devices including chronology, metaphor, characterisation, suspense and imagination were used to create persuasive accounts of a strange and frightening new condition that was beset with setbacks and overlooked or dismissed by health professionals. The most unique feature of long Covid narratives (in most but not all cases) was the absence, for various pandemic-related reasons, of a professional witness to them. Instead of sharing their narratives in therapeutic dialogue with their own clinician, people struggled with a fragmented inner monologue before finding an empathetic audience and other resonant narratives in the online community. Individually, the stories seemed to make little sense. Collectively, they provided a rich description of the diverse manifestations of a grave new illness, a shared account of rejection by the healthcare system, and a powerful call for action to fix the broken story. Evolving from individual narrative postings to collective narrative drama, long Covid communities challenged the prevailing model of Covid-19 as a short-lived respiratory illness which invariably delivers a classic triad of symptoms; undertook and published peer-reviewed research to substantiate its diverse and protracted manifestations; and gained positions as experts by experience on guideline development groups and policy taskforces.

Identification of EpCAM as the gene for congenital tufting enteropathy.

BACKGROUND & AIMS: Congenital tufting enteropathy (CTE) is a rare autosomal recessive diarrheal disorder presenting in the neonatal period. CTE is characterized by intestinal epithelial cell dysplasia leading to severe malabsorption and significant morbidity and mortality. The pathogenesis and genetics of this disorder are not well understood. The objective of this study was to identify the gene responsible for CTE. METHODS: A family with 2 children affected with CTE was identified. The affected children are double second cousins providing significant statistical power for linkage. Using Affymetrix 50K single nucleotide polymorphism (SNP) chips, genotyping was performed on only 2 patients and 1 unaffected sibling. Direct DNA sequencing of candidate genes, reverse-transcription polymerase chain reaction, immunohistochemistry, and Western blotting were performed on specimens from patients and controls. RESULTS: SNP homozygosity mapping identified a unique 6.5-Mbp haplotype of homozygous SNPs on chromosome 2p21 where approximately 40 genes are located. Direct sequencing of genes in this region revealed homozygous G>A substitution at the donor splice site of exon 4 in epithelial cell adhesion molecule (EpCAM) of affected patients. Reverse-transcription polymerase chain reaction of duodenal tissue demonstrated a novel alternative splice form with deletion of exon 4 in affected patients. Immunohistochemistry and Western blot of patient intestinal tissue revealed decreased expression of EpCAM. Direct sequencing of EpCAM from 2 additional unrelated patients revealed novel mutations in the gene. CONCLUSIONS: Mutations in the gene for EpCAM are responsible for CTE. This information will be used to gain further insight into the molecular mechanisms of this disease.

Process improvement for follow-up radiology report recommendations of lung nodules.

In the modern healthcare system, there are still wide gaps of communication of imaging results to physician and patient stakeholders and tracking of whether follow-up has occurred. Patients are also unaware of the significance of findings in radiology reports. With the increase in use of cross-sectional imaging such as CT, patients are not only being diagnosed with primary urgent findings but also with incidental findings such as lung nodules; however, they are not being told of their imaging findings nor what actions to take to mitigate their risks. In addition, patients at high risk for developing lung cancer often obtain serial CT scans, but tracking these patients is challenging for the clinician. In order to advance quality improvement goals and improve patient outcomes, we developed a custom application and business process for radiology practitioners that mines available healthcare data, identifies patients with lung nodules in need of follow-up imaging, notifies the patient and the primary care physician via mail, and measures process efficacy via executed follow-up screenings and captured patient condition. This integrated analytics and communication process increased our average rate of patient follow-ups for lung nodules from 26.50 in 2015 to 59.72% in 2017. 17.18% of these patients had new lung nodules or worsening severity of lung findings detected at follow-up. This new process has added missing quality and care coordination to an at-risk patient population. Problem: Communication of imaging results and follow-up recommendations to patients and primary care providers (PCPs) is a challenge for healthcare systems. In addition, tracking whether a patient's follow-up has been completed is another significant gap in care coordination. Patients are often unaware of or cannot even understand the significance of radiology findings or follow-up recommendations reported after imaging procedures. In addition, patients may not have a primary physician listed at time of imaging if the first encounter is in the emergency room (ER) or if their primary care physician or specialist works in a different electronic health record platform. Communication of imaging results to different healthcare providers is challenging with the myriad of existing electronic health record systems that often lack interoperability with other clinical entities.Description of lung nodules in radiology reports can vary widely if a standardised lexicon is not used. Moreover, follow-up recommendations by radiologists can be varied for certain size lung nodules because an individual's risk factors to develop lung cancer may not be known at the time of dictation.Approximately 500 000 radiology imaging procedures are interpreted and performed annually by a single private group of 33 radiologists located at a 665-bed regional referral centre and at a 140-bed acute care community hospital, both located in the suburbs of a major metropolitan city. Management of this volume of patients in the health system can be overwhelming to nurse navigators, and there is usually no system in place for primary care physicians to follow-up lung nodules found unexpectedly on inpatient images. The goal of this project was to develop a better automated tracking method and communication tool to reduce the likelihood that needed follow-up studies are missed by patients and clinicians.

A new syndrome of tufting enteropathy and choanal atresia, with ophthalmologic, hematologic and hair abnormalities.

Three siblings are reported with a syndrome of intractable diarrhea of infancy (owing to tufting enteropathy) and choanal atresia/stenosis. Additional components of this condition are a mild shortness of stature, a prominent and broad nasal bridge, micrognathia, single palmar creases, chronic corneal inflammation, episodic cytopenia, and abnormal hair texture. Intelligence is normal, and there is no immunodeficiency distinguishing this syndrome from that reported by Girault et al. (1994). Additional features that might occur in this syndrome include bifid uvula, preauricular pits, and 2/3 toe syndactyly. We compare this syndrome with previously reported intractable diarrhea syndromes and speculate on the developmental mechanisms that could account for many of the features demonstrated by this sibship.

Percutaneous malathion absorption by anuran skin in flow-through diffusion cells.

There is increased concern about the sublethal effects of organophosphorous (OP) compounds on human and animal health, including the potential role of OP compounds in the global decline of amphibian populations. Malathion is one of the most widely used OP pesticides with numerous agricultural and therapeutic applications, and exposure to environmentally applied malathion can lead to adverse systemic effects in anurans. Cutaneous absorption is considered a potentially important route of environmental exposure to OP compounds for amphibians, especially in aquatic environments. One in vitro system commonly used to determine the absorption kinetics of xenobiotics across the skin is the two-compartment Teflon flow-through diffusion cell system. To establish cutaneous absorption kinetics of malathion, six full thickness skin samples taken from both the dorsal and ventral surfaces of each of three bullfrogs (Rana catesbeiana) and three marine toads (Bufo marinus) were placed into two-compartment Teflon flow-through diffusion cells perfused with modified amphibian Ringer's solution. A 26µg/cm(2) dose of malathion-2,3-(14)C diluted in 100% ethanol was applied to each sample (0.44-0.45µCi). Perfusate was collected at intervals over a 6h period and analyzed for (14)C in a scintillation counter. At the end of 6h, surface swabs, tape strips, biopsy punches of the dosed area of skin, and peripheral samples were oxidized and analyzed for residue effects. Malathion absorption was greater across the ventral skin compared to dorsal skin in both bullfrogs and marine toads.

Percutaneous malathion absorption in the harvested perfused anuran pelvic limb.

The objective of this study was to establish an accurate in vitro model for cutaneous absorption in anurans. The harvested perfused anuran pelvic limb (HPAPL) model maintains the anatomic and physiologic integrity of the skin from the pelvic limb, including the intact capillary network. Radiolabeled malathion was applied to the skin of the dorsal thigh, and perfusate was collected over a 6h period. Residues from the skin surface, stratum externum, and dosed area beneath the stratum externum were analyzed. Kinetic parameters were calculated from these data. Absorption was significantly less for the HPAPL than previously reported for Teflon flow-through diffusion cells. However, partitioning effects were comparable. The HPAPL is an appropriate in vitro model for examining cutaneous absorption kinetics in the bullfrog.
