Measuring the α-particle charge radius with muonic helium-4 ions.

The energy levels of hydrogen-like atomic systems can be calculated with great precision. Starting from their quantum mechanical solution, they have been refined over the years to include the electron spin, the relativistic and quantum field effects, and tiny energy shifts related to the complex structure of the nucleus. These energy shifts caused by the nuclear structure are vastly magnified in hydrogen-like systems formed by a negative muon and a nucleus, so spectroscopy of these muonic ions can be used to investigate the nuclear structure with high precision. Here we present the measurement of two 2S-2P transitions in the muonic helium-4 ion that yields a precise determination of the root-mean-square charge radius of the α particle of 1.67824(83) femtometres. This determination from atomic spectroscopy is in excellent agreement with the value from electron scattering1, but a factor of 4.8 more precise, providing a benchmark for few-nucleon theories, lattice quantum chromodynamics and electron scattering. This agreement also constrains several beyond-standard-model theories proposed to explain the proton-radius puzzle2-5, in line with recent determinations of the proton charge radius6-9, and establishes spectroscopy of light muonic atoms and ions as a precise tool for studies of nuclear properties.

Underwater Endoscopic Mucosal Resection Vs Conventional Endoscopic Mucosal Resection for Superficial Nonampullary Duodenal Epithelial Tumors in the Western Setting.

BACKGROUND & AIMS: Conventional endoscopic mucosal resection (C-EMR) is established as the primary treatment modality for superficial nonampullary duodenal epithelial tumors (SNADETs), but recently underwater endoscopic mucosal resection (U-EMR) has emerged as a potential alternative. The majority of previous studies focused on Asian populations and small lesions (≤20 mm). We aimed to compare the efficacy and outcomes of U-EMR vs C-EMR for SNADETs in a Western setting. METHODS: This was a retrospective multinational study from 10 European centers that performed both C-EMR and U-EMR between January 2013 and July 2023. The main outcomes were the technical success, procedure-related adverse events (AEs), and the residual/recurrent adenoma (RRA) rate, evaluated on a per-lesion basis. We assessed the association between the type of endoscopic mucosal resection and the occurrence of AEs or RRAs using mixed-effects logistic regression models (propensity scores). Sensitivity analyses were performed for lesions ≤20 mm or >20 mm. RESULTS: A total of 290 SNADETs submitted to endoscopic resection during the study period met the inclusion criteria and were analyzed (C-EMR: n = 201, 69.3%; U-EMR: n = 89, 30.7%). The overall technical success rate was 95.5% and comparable between groups. In logistic regression models, compared with U-EMR, C-EMR was associated with a significantly higher frequency of overall delayed AEs (odds ratio [OR], 4.95; 95% CI, 2.87-8.53), postprocedural bleeding (OR, 7.92; 95% CI, 3.95-15.89), and RRAs (OR, 3.66; 95% CI, 2.49-5.37). Sensitivity analyses confirmed these results when solely considering either small (≤20 mm) or large (>20 mm) lesions. CONCLUSIONS: Compared with C-EMR, U-EMR was associated with a lower rate of overall AEs and RRAs, regardless of lesion size. Our results confirm the possible role of U-EMR as an effective and safe technique in the management of SNADETs.

Hanle Effect for Lifetime Determinations in the Soft X-Ray Regime.

By exciting a series of 1s^{2} ^{1}S_{0}→1snp^{1}P_{1} transitions in heliumlike nitrogen ions with linearly polarized monochromatic soft x rays at the Elettra facility, we found a change in the angular distribution of the fluorescence sensitive to the principal quantum number n. In particular it is observed that the ratio of emission in directions parallel and perpendicular to the polarization of incident radiation increases with higher n. We find this n dependence to be a manifestation of the Hanle effect, which served as a practical tool for lifetime determinations of optical transitions since its discovery in 1924. In contrast to traditional Hanle effect experiments, in which one varies the magnetic field and considers a particular excited state, we demonstrate a "soft x-ray Hanle effect" which arises in a static magnetic field but for a series of excited states. By comparing experimental data with theoretical predictions, we were able to determine lifetimes ranging from hundreds of femtoseconds to tens of picoseconds of the 1snp^{1}P_{1} levels, which find excellent agreement with atomic-structure calculations. We argue that dedicated soft x-ray measurements could yield lifetime data that are beyond current experimental reach and cannot yet be predicted with sufficient accuracy.

Endoscopic transmural resection as an alternative to colorectal surgery after high-risk (non-curative) endoscopic resection.

Endoscopic full-thickness resection (eFTR) is an emerging technique that enables effective and safe management of complex colorectal lesions. The full-thickness resection device (FTRD®, Ovesco, Germany) has primarily been used for non-exposed transmural resection of challenging subepithelial or epithelial lesions, where conventional methods may be limited. This technique represents an alternative to surgery in selected patients, and its applications are rapidly expanding. In recent years, eFTR has been described as an alternative to surgery for scars aiming to exclude residual tumors after non-curative endoscopic resection. We present a case of a 41-year-old woman with Lynch syndrome (dMLH1) with rectal adenocarcinoma at the age of 20 underwent anterior resection of the rectum and adjuvant chemoradiotherapy. At the age of 39, during endoscopic surveillance, she presented with a suspicious lesion (Paris 0-Is+IIa, NICE2, JNET2B) measuring 16mm in the hepatic angle, and underwent en bloc endoscopic mucosal resection (EMR). Histopathological analysis revealed a low-grade invasive adenocarcinoma with lymphoid stroma with deep invasion of the submucosa and resection margin involvement (vertical R1). After a multidisciplinary team discussion, complementary surgery was proposed but the patient refused, opting for close endoscopic and imaging surveillance. Two subsequent colonoscopies plus computed tomography (CT) scans showed no signs of macro or microscopic residual or recurrent tumor, even after extensive biopsies of the colonic scar. However, a CT scan 20months post-resection showed a de novo 2cm thickening of the parietal wall in the hepatic angle, consistent with the location of the previous endoscopic resection. Suspecting deep parietal tumor recurrence without superficial endoscopic findings, a transmural endoscopic resection using FTRD® of the EMR scar was performed, whose histology revealed no transparietal tumor recurrence.

Predicting residual neoplasia after a non-curative gastric ESD: validation and modification of the eCura system in the Western setting: the W-eCura score.

OBJECTIVE: To evaluate the risk factors for lymph node metastasis (LNM) after a non-curative (NC) gastric endoscopic submucosal dissection (ESD) and to validate and eventually refine the eCura scoring system in the Western setting. Also, to assess the rate and risk factors for parietal residual disease. DESIGN: Retrospective multicentre multinational study of prospectively collected registries from 19 Western centres. Patients who had been submitted to surgery or had at least one follow-up endoscopy were included. The eCura system was applied to assess its accuracy in the Western setting, and a modified version was created according to the results (W-eCura score). The discriminative capacities of the eCura and W-eCura scores to predict LNM were assessed and compared. RESULTS: A total of 314 NC gastric ESDs were analysed (72% high-risk resection (HRR); 28% local-risk resection). Among HRR patients submitted to surgery, 25% had parietal disease and 15% had LNM in the surgical specimen. The risk of LNM was significantly different across the eCura groups (areas under the receiver operating characteristic curve (AUC-ROC) of 0.900 (95% CI 0.852 to 0.949)). The AUC-ROC of the W-eCura for LNM (0.916, 95% CI 0.870 to 0.961; p=0.012) was significantly higher compared with the original eCura. Positive vertical margin, lymphatic invasion and younger age were associated with a higher risk of parietal residual lesion in the surgical specimen. CONCLUSION: The eCura scoring system may be applied in Western countries to stratify the risk of LNM after a gastric HRR. A new score is proposed that may further decrease the number of unnecessary surgeries.

Iron pill-induced gastritis: an unrecognized side effect of iron-deficiency anemia.

Iron-deficiency anemia is a prevalent condition usually treated with iron supplementation. Iron pill-induced gastritis is an under-recognized, albeit serious potential complication of iron pill ingestion in the upper gastrointestinal tract. This entity must be identified by healthcare providers who prescribe iron. The diagnosis of this unusual drug-induced disease is based on endoscopic findings and histopathological examination, because the clinical symptoms are vague and non-specific. Herein we report a case of a 79-year-old woman with iron-deficiency anemia taking oral ferrous sulfate with multiple congestive and eroded polypoid lesions. Histology showed an H. pylori-negative erosive gastritis with iron deposition, confirming the diagnosis of iron pill-induced gastritis. The aim of this report is to highlight that iron pill-induced gastritis is an under-diagnosed entity that must be kept in mind when patients undergo chronic iron-pill therapy because it can lead to serious complications of the upper gastrointestinal tract.

Diagnostic accuracy of clinical tests directed to the long head of biceps tendon in a surgical population: a combination of old and new tests.

BACKGROUND: Our objective was to examine the clinical utility of old and new clinical tests directed to the long head of the biceps tendon (LHBT) and to quantify the importance of proper test interpretation. METHODS: A consecutive 65 patients scheduled to undergo arthroscopic surgery were selected. Before surgery, 5 clinical tests were performed: Speed, Yergason, upper cut, biceps resisted flexion (BRF), and modified BRF (mBRF) using a dumbbell. Pain in an area other than the bicipital groove was noted. The presence of LHBT disease was assessed at arthroscopy, and the clinical utility of the tests was calculated. RESULTS: The upper cut test was the most sensitive test and the one with the lowest negative likelihood ratio (0.90 and 0.26, respectively); the Yergason test was the most specific and the one with the highest positive likelihood ratio (0.83 and 2.20, respectively). BRF strength did not correlate with an LHBT lesion. The mBRF test has a sensitivity of 0.34 and a specificity of 0.75. Higher age predicted an increased risk of an LHBT lesion (1.2 times). Different interpretations of the tests can result in a difference of up to 29 percentage points in performance (ie, sensitivity). CONCLUSION: Our results suggest that the upper cut test should be used as a screening test and that after a positive result, the Speed and the Yergason tests should be used as confirmatory tests.

Association between the location of colon polyps at baseline and surveillance colonoscopy - A retrospective study.

INTRODUCTION: Several factors are used to stratify the probability of polyp recurrence. However, there are no studies correlating the location of the initial polyps and the recurrent ones. The aim of this study was to verify whether the polyp location at the surveillance colonoscopy was correlated with the location of the previously excised polyps at the baseline colonoscopy. METHODS: A retrospective study of patients submitted to colonoscopy with presence and excision of all polyps, followed by a surveillance colonoscopy. Polyp location was divided into proximal/distal to splenic flexure and rectum. Characteristics and recurrent rates at the same colon location were also evaluated. RESULTS: Out of the 346 patients who underwent repeated colonoscopy, 268 (77.4%) had at least 1 polyp detected. For all the segments there was an increased risk of recurrent polyps in the same location and it was about four times higher in proximal (OR 3.5; CI 2.1-6.0) and distal colon segments (OR 3.8; CI 2.1-6.8), followed by three times higher in the rectum (OR 2.6; CI 1.5-4.6). No difference was found between the rates of recurrence at the same segment, taking into consideration the polyp morphology, size, polypectomy technique employed and histological classification. CONCLUSION: There seems to be a significant association between polyp location at baseline and surveillance colonoscopy.

Long segments of columnar-lined lower esophagus are not always metaplastic.

The presence of columnar epithelium in the esophagus is associated with two conditions: Barrett's esophagus and heterotopic gastric mucosa. The former results from the metaplastic replacement of the normal distal squamous esophageal lining, is associated with gastroesophageal reflux and is a pre-neoplastic condition. The second is thought as a congenital condition, resulting from the incomplete squamous epithelialization of the esophagus during embryologic development. It is found mainly in the cervical esophagus. Histologically, Barrett's esophagus is composed of an admixture of cardiac mucosa, oxintocardiac mucosa and intestinal metaplasia. Most of heterotopic gastric mucosa consists of oxynticmucosa where the mucosal glands are straight and composed of parietal and chief cells.There are few reports of heterotopic gastric mucosa in the lower esophagus, generally presenting as small islands. In the present report, a series of four cases of large lower esophageal heterotopic gastric mucosa is described. All patients were initially misdiagnosed with Barrett's esophagus and referred for surveillance. The correct diagnosis was based in endoscopic and histological features. In all, a circular tiny strip of squamous mucosa was observed at endoscopy between the lower end of the columnarlined esophagus and the esophagogastric junction, defined as the proximal end of the gastric folds. Biopsy samples taken from the columnar-lined segments of the four patients showed pure oxyntic mucosa.When columnar-lined esophagus is observed in the distal esophagus not in continuity with gastric mucosa, the diagnosis of heterotopic gastric mucosa must be thought and confirmed histologically by the presence of pure oxyntic mucosa.

Psychotherapeutic interventions for depressive symptoms in older adults in a community setting: a systematic review protocol.

Depression is a prevalent illness among the elderly, so psychotherapeutic interventions are needed to promote health and quality of life. This literature review aims to identify trials of any psychotherapeutic interventions aimed at reducing depressive symptoms in older adults. A systematic literature review with a meta-analysis will be carried out. The following databases will be searched: CINAHL Plus with Full Text, MedicLatina, MEDLINE with Full Text, and Psychology and Behavioral Sciences Collection. To minimize bias, four reviewers will independently assess the inclusion of studies. The fifth reviewer will be responsible for disaggregating inclusion and exclusion between two authors. The results of the analysis will be grouped in a table with the characteristics of the included studies, including author, year, sample, objectives, methods, assessment instruments, psychotherapeutic interventions, results, follow-up and a data compilation scheme. This scientific article is a systematic review protocol for which the data has already been extracted and is being analyzed. Examples of possible strategies to include cognitive restructuring and mental health programs for older adults in community settings. With this clear and direct identification of psychotherapeutic interventions, it will be clearer for mental health professionals to be able to intervene effectively to promote the mental health and well-being of older adults. PROSPERO registration number: CRD42023449190.

"Geriatric Proximity" Intervention in COVID-19 Context: Contribution to Reducing Loneliness and Improving Affectivity.

(1) Background: The pandemic context has limited the social and family contacts of institutionalized older adults, and intervention is urgently needed. The aim of this study is to assess the impact of the implementation of a "Geriatric Proximity" intervention on the functioning, satisfaction with social support, affective experience, and feelings of loneliness of institutionalized older adults in the times of the pandemic. (2) Methods: This is a pilot study. An experimental group (subject to the "Geriatric Proximity" intervention) and a control group were constituted. Four assessment instruments were applied to both groups: the satisfaction with social support scale; the elderly nursing core set; the positive and negative affect schedule; and the UCLA loneliness scale. (3) Results: The control group shows no differences between the three measurement instants, while the experimental group shows between first and third measurements (all p < 0.05). We observed a reduction in the scores of loneliness scale, negative affect, and cognition functioning and an increase in satisfaction with social support and positive affect. (4) Conclusions: The intervention "Geriatric Proximity" showed a positive contribution by decreasing loneliness and increasing affectivity, satisfaction with social support, and cognitive function during the pandemic period.

Successful Endoscopic Closure of Esophageal Perforation in Boerhaave Syndrome Using the Over-the-Scope Clip.

Boerhaave syndrome (BS) is a rare but potentially fatal condition. Although surgery is considered the standard treatment, endoscopic therapy has acquired an important role as a minimally invasive management approach. The authors describe 2 cases of middle-aged male patients, presenting with spontaneous esophageal perforation after severe straining and vomiting. In the first case, the patient presented with a bone impaction in the upper esophagus successfully removed by rigid esophagoscopy. After the procedure, a chest X-ray/cervicothoracic computerized tomography scan (CT) showed a left hydropneumothorax and pneumomediastinum with oral contrast leak at the lower esophagus. In the second case, the patient presented to the Emergency Department with severe chest pain after an episode of vomiting. The CT showed a massive pneumomediastinum, subcutaneous emphysema, and an oral contrast leak compatible with BS. The patient was initially submitted to surgical suture, but contrast extravasation persisted after 12 days. After multidisciplinary team discussion of both patients, an upper gastrointestinal endoscopy was performed, which revealed pericentimetric wall defects at the distal esophagus. These were successfully closed using an over-the-scope clip (OTSC). After at least a 9-month follow-up, patients have remained clinically well with no relapse. The authors highlight the severity of these clinical cases and the endoscopic option that proved to be decisive in addressing BS. The favorable outcomes suggest a role for the OTSC approach in closing spontaneous esophageal perforation both as first-line and as rescue therapy after a surgical failure.

A síndrome de Boerhaave (SB) é uma entidade rara, mas potencialmente fatal. Embora a cirurgia seja o tratamento padrão, o tratamento endoscópico tem adquirido um papel importante como opção minimamente invasiva. Os autores descrevem dois casos de doentes do sexo masculino de meia-idade, que apresentaram perfuração esofágica espontânea após esforço emético intenso e vómitos. No primeiro caso, o doente apresentou impactação de um osso no esófago superior, que foi removido com sucesso por esofagoscopia rígida. Após o procedimento, o doente realizou radiografia de tórax e tomografia computorizada (TC) cervico-torácica que evidenciou hidropneumotórax esquerdo e pneumomediastino com extravasamento de contraste oral ao nível do esófago inferior. No segundo caso, o doente apresentou-se no Serviço de Urgência com toracalgia intensa após episódio de vómito. A TC mostrou pneumomediastino exuberante, com enfisema subcutâneo e extravasamento de contraste oral compatível com SB. O doente foi inicialmente submetido a rafia cirúrgica, mas o esofagograma ao 12º dia mostrou persistência de extravasamento do contraste. Após discussão em reunião multidisciplinar, ambos os doentes realizaram endoscopia digestiva alta, com visualização de orifícios pericentimétricos no esófago distal, encerrados com sucesso com a aplicação de clip overthe- scope (OTSC). Após seguimento de pelo menos 9 meses, os doentes permaneceram clinicamente bem, sem evidência de recidiva. Os autores destacam a gravidade desses casos clínicos, bem como a opção endoscópica que se mostrou decisiva no tratamento da SB. Os resultados favoráveis sugerem um papel para a abordagem com OTSC no tratamento da perfuração esofágica espontânea, tanto como tratamento de primeira linha, como terapêutica de resgate após falência do tratamento cirúrgico.

Absolute measurement of the relativistic magnetic dipole transition energy in heliumlike argon.

The 1s2s (3)S(1)→1s(2) (1)S(0) relativistic magnetic dipole transition in heliumlike argon, emitted by the plasma of an electron-cyclotron resonance ion source, has been measured using a double-flat crystal x-ray spectrometer. Such a spectrometer, used for the first time on a highly charged ion transition, provides absolute (reference-free) measurements in the x-ray domain. We find a transition energy of 3104.1605(77) eV (2.5 ppm accuracy). This value is the most accurate, reference-free measurement done for such a transition and is in good agreement with recent QED predictions.

X-linked hypophosphataemic rickets: Report of a novel PHEX mutation and cinacalcet as adjuvant therapy in the mineral metabolism control.

X-linked hypophosphataemic rickets (XLH) is a rare disease caused by a mutation in the phosphate-regulating neutral endopeptidase (PHEX) gene, located on the X chromosome. This gene encodes the phosphate-regulating endopeptidase, and its inactivation leads to increased levels of circulating phosphatonins responsible for renal phosphate loss. The treatment for XLH is still carried out with long-term administration of phosphate and calcitriol, which can be complicated by hyperparathyroidism, nephrocalcinosis, renal failure, and hypertension. We describe the case of a four-decade follow-up patient with XLH. When she was diagnosed, at 19 years, due to bone pain and deformities, she was put on therapy with phosphorus and cholecalciferol. Despite the clinical improvement, serum phosphorus remained difficult to control. At the age of 44 years, she developed tertiary hyperparathyroidism and was submitted to parathyroidectomy. Five years later, parathyroid hyperfunction recurred. This time, cinacalcet was started, 30 mg alternating with 60 mg/day. Currently, she is 59-years old and remains with controlled mineral metabolism. The genetic study of this patient revealed a nonsense heterozygous mutation (c.501G>A) in PHEX gene that was not previously described. In this case, the off-label use of cinacalcet resulted in the normalisation of serum parathormone and phosphorus levels, eliminated recurrent secondary hyperparathyroidism, which aggravates the bone fragility inherent to XLH, and prevented a new parathyroidectomy. This report also adds important information to the genetic basis of XLH with the identification of a new nonsense mutation of the PHEX gene.

An Atypical Presentation of a Colonic Lipoma: Avoiding Surgery with a Deeper Endoscopic Look.

INTRODUCTION: Colonic lipomas are common mesenchymal tumours. They are usually asymptomatic and incidentally diagnosed during endoscopic or radiological examinations. Taking into account their typical endoscopic and radiological features and benign nature, tissue sampling, resection or follow-up are generally not required. CASE REPORT: A 61-year-old woman with poor surgical fitness presented with colonic subocclusion and lower gastrointestinal bleeding. A colonoscopy performed 1 month earlier showed a large polypoid lesion with necrotic and ulcerated areas occupying the lumen of the proximal ascending colon with inconclusive histology. An abdominopelvic computed tomography scan with intravenous contrast was done revealing a cecal-colonic intussusception of a heterogeneous mass. The patient was successfully managed conservatively. A delayed revision colonoscopy showed a significantly smaller atypical subepithelial lesion with no necrosis or ulceration. A single, large and deep incision with a pre-cut needle-knife® allowed the direct collection of lesion tissue using standard biopsy forceps through the so-called single-incision needle-knife® (SINK) biopsy technique. Histological examination was compatible with submucosal lipoma. After 18 months of follow-up, the patient remains asymptomatic. DISCUSSION/CONCLUSION: Colonic lipoma complications are rare and can lead to misdiagnosis; in general, they are surgically managed. A conservative approach and a minimally invasive endoscopic procedure allowed a definite diagnosis avoiding the morbidity and mortality of a major surgical intervention in a high-risk patient.

INTRODUÇÃO: Os lipomas do cólon são tumores mesenquimatosos comuns. Frequentemente são assintomáticos e diagnosticados, incidentalmente, em exames endoscópicos e imagiológicos. O diagnóstico histológico, resseção e vigilância não costumam ser necessários devido aos achados endoscópicos e imagiológicos típicos e à sua natureza benigna. CASO CLÍNICO: Uma mulher de 61 anos com contraindicação relativa para cirurgia abdominal recorreu ao serviço de urgência por quadro clínico de suboclusão intestinal e hemorragia digestiva baixa. A colonoscopia, realizada um mês antes, demonstrava uma lesão polipoide com área de necrose e ulceração a ocupar o lúmen do cólon ascendente proximal, com estudo histológico inconclusivo. Foi efetuada uma tomografia computorizada abdominopélvica com contraste intravenoso que revelou uma invaginação ceco-cólica de uma massa heterogénea.Optou-se por uma abordagem conservadora com remissão clínica. A colonoscopia de revisão diferida mostrou, na mesma localização, uma lesão subepitelial de menores dimensões, atípica, sem ulceração ou necrose. Com uma faca-agulha de pré-corte foi efetuada uma incisão única e profunda que permitiu a colheita direta de material usando uma pinça de biopsias standard através da técnica denominada biopsia por faca-agulha de précorte de incisão única. A análise histológica foi compatível com lipoma submucoso. Cerca de 18 meses após o episódio a doente permanece assintomática. DISCUSSÃO/CONCLUSÃO: As complicações do lipoma do cólon são raras e podem levar a um diagnóstico erróneo, geralmente tratado cirurgicamente. Uma abordagem conservadora inicial e um procedimento endoscópico minimamente invasivo permitiram o diagnóstico definitivo, evitando a morbilidade e mortalidade associadas a uma intervenção cirúrgica major numa doente de alto risco.

Factors Associated with Withdrawal Time in European Colonoscopy Practice: Findings of the European Colonoscopy Quality Investigation (ECQI) Group.

The European Colonoscopy Quality Investigation (ECQI) Group aims to raise awareness for improvement in colonoscopy standards across Europe. We analyzed data collected on a sample of procedures conducted across Europe to evaluate the achievement of the European Society of Gastrointestinal Endoscopy (ESGE) mean withdrawal time (WT) target. We also investigated factors associated with WT, in the hope of establishing areas that could lead to a quality improvement. METHODS: 6445 form completions from 12 countries between 2 June 2016 and 30 April 2018 were considered for this analysis. We performed an exploratory analysis looking at WT according to the ESGE definition. Stepwise multivariable logistic regression analysis was conducted to determine the most influential associated factors after adjusting for the other pre-specified variables. RESULTS: In 1150 qualifying colonoscopies, the mean WT was 7.8 min. Stepwise analysis, including 587 procedures where all inputs were known, found that the variables most associated with mean WT were a previous total colonoscopy in the last five years (p = 0.0011) and the time of day the colonoscopy was performed (p = 0.0192). The main factor associated with a WT < 6 min was the time of day that a colonoscopy was performed. Use of sedation was the main factor associated with a higher proportion of WT > 10 min, along with a previous colonoscopy. CONCLUSIONS: On average, the sample of European practice captured by the ECQI survey met the minimum standard set by the ESGE. However, there was variation and potential for improvement.

Factors Associated with Polyp Detection Rate in European Colonoscopy Practice: Findings of The European Colonoscopy Quality Investigation (ECQI) Group.

Background: The European Colonoscopy Quality Investigation (ECQI) Group aims to raise awareness for improvement in colonoscopy standards across Europe. We analysed data collected on a sample of procedures conducted across Europe to evaluate the achievement of the polyp detection rate (PDR) target. We also investigated factors associated with PDR, in the hope of establishing areas that could lead to a quality improvement. Methods: 6445 form completions from 12 countries between 2 June 2016 and 30 April 2018 were considered for this analysis. We performed an exploratory analysis looking at PDR according to European Society of Gastrointestinal Endoscopy (ESGE) definition. Stepwise multivariable logistic regression analysis was conducted to determine the most influential associated factors after adjusting for the other pre-specified variables. Results: In our sample there were 3365 screening and diagnostic procedures performed in those over 50 years. The PDR was 40.5%, which is comparable with the ESGE minimum standard of 40%. The variables found to be associated with PDR were in descending order: use of high-definition equipment, body mass index (BMI), patient gender, age group, and the reason for the procedure. Use of HD equipment was associated with a significant increase in the reporting of flat lesions (14.3% vs. 5.7%, p < 0.0001) and protruded lesions (34.7% vs. 25.4%, p < 0.0001). Conclusions: On average, the sample of European practice captured by the ECQI survey meets the minimum PDR standard set by the ESGE. Our findings support the ESGE recommendation for routine use of HD colonoscopy.

Prognostic scores in cirrhotic patients admitted to a gastroenterology intensive care unit.

BACKGROUND: prognostic scores have been validated in cirrhotic patients admitted to general Intensive Care Units. No assessment of these scores was performed in cirrhotics admitted to specialized Gastroenterology Intensive Care Units (GICUs). AIM: to assess the prognostic accuracy of Acute Physiology and Chronic Health Evaluation (APACHE) II, Simplified Acute Physiology Score (SAPS) II, Sequential Organ Failure Assessment (SOFA), Model for End-stage Liver Disease (MELD) and Child-Pugh-Turcotte (CPT) in predicting GICU mortality in cirrhotic patients. METHODS: the study involved 124 consecutive cirrhotic admissions to a GICU. Clinical data, prognostic scores and mortality were recorded. Discrimination was evaluated with area under receiver operating characteristic curves (AUC). Calibration was assessed with Hosmer-Lemeshow goodness-of-fit test. RESULTS: GICU mortality was 9.7%. Mean APACHE II, SAPS II, SOFA, MELD and CPT scores for survivors (13.6, 25.4, 3.5,18.0 and 8.6, respectively) were found to be significantly lower than those of non-survivors (22.0, 47.5, 10.1, 30.7 and 12.5,respectively) (p < 0.001). All the prognostic systems showed good discrimination, with AUC = 0.860, 0.911, 0.868, 0.897 and 0.914 for APACHE II, SAPS II, SOFA, MELD and CPT, respectively. Similarly, APACHE II, SAPS II, SOFA, MELD and CPT scores achieved good calibration, with p = 0.146, 0.120, 0.686,0.267 and 0.120, respectively. The overall correctness of prediction was 81.9%, 86.1%, 93.3%, 90.7% and 87.7% for the APA-CHE II, SAPS II, SOFA, MELD and CPT scores, respectively. CONCLUSIONS: in cirrhotics admitted to a GICU, all the tested scores have good prognostic accuracy, with SOFA and MELD showing the greatest overall correctness of prediction.
