Comparison of risk scoring systems for critical care patients with upper gastrointestinal bleeding: predicting mortality and length of stay.

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is a common reason for intensive care admission. While there exist a number of UGIB scoring systems which are used to predict mortality, there are limited studies assessing the discriminative value of these scores in intensive care unit (ICU) patients. The purpose of this study was to analyse five different UGIB scoring systems in predicting ICU mortality and length of stay and compare them to two commonly used ICU mortality scoring systems. MATERIAL AND METHODS: We retrospectively identified all patients requiring ICU admission for UGIB to St James's Hospital over an 18-month period. We calculated their AIM65, Glasgow- Blatchford score, pre- and post-Rockall score, ABC, APACHE II and SOFA scores. We used area under the receiver operating characteristic curve (AUROC) to compare the predictive values of these six scoring systems for ICU and hospital mortality as well as ICU length of stay greater than seven days. RESULTS: APACHE II showed excellent discriminative value in predicting mortality in ICU patients (AUROC: 0.87; CI: 0.75-0.99) while the SOFA score showed good discriminative value (AUROC: 0.71; CI: 0.50-0.93). None of the UGIB scoring systems predicted mortality in these patients. All scoring systems showed poor discriminative value in predicting ICU length of stay. CONCLUSIONS: We were not able to validate any of these UGIB scoring systems for mortality or length of stay prediction in ICU patients. This study supports the validity of APACHE II as a clinical tool for predicting mortality in ICU patients with UGIB.

Rash morphology as a predictor of COVID-19 severity: A systematic review of the cutaneous manifestations of COVID-19.

Approximately 6% of those with COVID-19 will experience cutaneous manifestations. Examining data from this cohort could provide useful information to help with the management of COVID-19. To that end, we conducted a systematic review primarily to assess rash morphologies associated with COVID-19 and their relationship with disease severity. Secondary outcomes include demographics, distribution, dermatological symptoms, timeline, diagnostic method and medication history. The literature was searched for all patients with skin manifestations thought to be related to suspected or confirmed COVID-19. Patients with a history of dermatological, rheumatological or occupational skin disorders were excluded. Of the 2056 patients selected, the most common morphologies were chilblain-like lesions (54.2%), maculopapular (13.6%) and urticaria (8.3%). Chilblain-like lesions were more frequent in the younger population (mean age 21.5, standard deviation ± 10.8) and were strongly linked with milder disease, not requiring an admission (odds ratio [OR] 35.36 [95% confidence interval {CI} 23.58, 53.03]). Conversely, acro-ischaemia and livedo reticularis were associated with worse outcomes, including a need for ICU (OR 34.01 [95% CI 16.62, 69.57] and OR 5.57 [95% CI 3.02, 10.30], respectively) and mortality (OR 25.66 [95% CI 10.83, 60.79] and OR 10.71 [95% CI 4.76, 24.13], respectively). Acral lesions were the most common site (83.5%). 35.1% experienced pruritus, 16.4% had pain and 4.7% reported a burning sensation. 34.1% had asymptomatic lesions. Rash was the only symptom in 20.9% and occurred before or alongside systemic symptoms in 12.4%. 28.3% had a positive polymerase chain reaction nasopharyngeal swab and 5.4% had positive antibodies, while 21.9% tested negative and 45.1% were not tested. In conclusion, COVID-19 causes a variety of rashes, which may cause symptoms and add to morbidity. Rash type could be helpful in determining COVID-19 prognosis.

Predictors of Stone-Related Events in Asymptomatic Untreated Intrarenal Calculi.

Purpose: There is a lack of data on the natural history of asymptomatic intrarenal calculi. In this study, we investigate stone-related events (SREs) in patients with untreated intrarenal calculi. We also investigate predictive factors for SREs. Methods: All patients found with an asymptomatic intrarenal calculus on CT kidney, ureter, bladder managed conservatively with interval imaging for ≥6 months were included. Patients were evaluated for any SRE. The rate of event according to calculus size, location, and number of calculi was also analyzed. Multivariate logistic regression analysis was performed to determine significant predictors for SREs. Results: In total, 266 renal units from 177 patients met inclusion criteria. The mean stone size was 4.44 mm (range 1-25 mm). Duration of follow-up was 43.78 ± 26.86 months (range 6-106 months). The overall rate of SREs, including intervention (n = 80) and spontaneous stone passage after ureteral colic (n = 40), was 45.1% (n = 120/266). Stones >5 mm were more likely to lead to an event compared with stones ≤5 mm (odds ratio [OR]: 2.94; p = 0.01). Interpolar stones and stones located in multiple calices were more likely to cause a SRE than lower pole stones (OR: 2.05; p = 0.05 and OR: 2.29; p = 0.03, respectively). Conclusion: In this large series of patients with asymptomatic intrarenal calculi, the incidence of a spontaneous SRE was 45.1% after 41 months. Stone size and stone location were significant predictors for a SRE. Information from this study will enable urologists to accurately risk stratify patients with asymptomatic renal stones.

Collaboration, supervision and patient safety in the era of COVID-19: an analysis of medical wards and ICU.

AIMS: COVID-19 resulted in significant changes across medical wards and ICU in St James's Hospital Dublin. This included the implementation of ward-based medical teams (WBMT). The purpose of this study was to identify how these structural changes affected inter-professional collaboration, supervision and patient safety. METHODS: Questionnaires were distributed to doctors working on medical wards and ICU at the height of the first wave of COVID-19. The sense of collaboration, patient safety and supervision were assessed. RESULTS: Fifty-three doctors took part in the study. Thirty-three (62%) felt that collaboration was better than normal. Forty-six (87%) of participants described supervision as "good" or "excellent". Thirty-one out of 40 participants (77%) felt that patient safety was better than normal. DISCUSSION: Implementation of WBMT may result in improved sense of collaboration, supervision and patient safety during COVID-19; however, the increased sense of solidarity and comradery felt during the initial surge make drawing these conclusions challenging.

Unusual presentation of infective endocarditis in ICU.

Bacterial endocarditis remains a challenging condition to manage owing to its variety of different presentations. This report describes a 55-year-old woman with endocarditis who presented confused with shoulder and back pain. Initial diagnosis was made difficult by a negative echocardiogram but aided by striking peripheral stigmata. She was treated for infective endocarditis as she met all five Duke's minor criteria for infective endocarditis. Gallium scan was a useful investigation in identifying lumbar spine and acromioclavicular joint septic foci. This case highlights the challenges of diagnosing endocarditis. It also describes how gallium scans can be useful in identifying occult septic emboli in these patients.

Magnetic Resonance Imaging Features of Traumatic Patellofemoral Dislocation.

Acute traumatic patellar dislocations are encountered with relative frequency, making up 3% of all knee injuries. Typically witnessed in younger patients following sporting injuries, this injury can be debilitating, potentially leading to recurrent dislocation, pain, reduction in activity and patellofemoral osteoarthritis. Management of this injury remains controversial, and as such detailed magnetic resonance imaging (MRI) is increasingly recommended to help illustrate the exact nature of osteochondral and soft tissue injury, with a view to assessing the anatomical sequelae of patellar dislocation as well as the potential of recurrence and dictating the need for either conservative or surgical management in the acute setting. As such, awareness of the typical MRI findings in traumatic patellar dislocations may potentially aid in pursuing appropriate intervention for this pathology. This case describes a 33-year-old gentleman presenting to the emergency department following patellar dislocation. After failed departmental closed reduction, this patient progressed on to definitive anatomical MRI assessment followed by acute surgical intervention in the form of medial patellofemoral ligament (MPFL) repair. This case allows for both illustration and discussion of typical radiological features associated with traumatic patellar dislocation.
