Object: Some factors affect hospitalization time in patients with acute cerebral infarctionMethod: Cross-sectional, retrospective descriptive study including 150 patients with acute cerebral infarction treated at the Neurology Center and Stroke Center, Bach Mai Hospital from January 2023 to December 2023.Result: The average hospital admission time was 661.5 minutes (11 hours); Only 26 patients were hospitalized early before 4.5 hours, accounting for 17.3%; Factors affecting the early hospitalization time of patients are high educational level (OR: 2.362; 95% CI [1.002-5.565]), daytime onset time (OR: 3.787; 95% CI [ 0.081-0.996]), having a witness at the time of symptom onset (OR: 5.928; 95% CI [1.336-26.308]), using ambulance transportation (OR: 32.445; 95% CI [9,916-106,223]), history of stroke or TIA (OR: 5.9; 95% CI [1.73-20,121]), recognition of symptoms of stroke (OR: 256.82; 95% CI [31] ,69-2081.44]) and knowledge of fibrinolytic drugs (OR: 83.18; 95% CI [16.81-411.69]); Factors affecting the patient's late hospitalization time include: distance to the hospital >15km (OR: 0.33; 95% CI [0.117-0.931]), admission to a front-line medical facility (OR: : 0.165; 95% CI [0.054-0.507]).Conclusion: Factors affecting the patient's early hospitalization time include: high educational level, time of illness onset during the day, presence of witnesses at the time of symptom onset, use of public transport ambulance, history of stroke or TIA, recognition of stroke symptoms and knowledge of thrombolytic drugs.

External validation of a stepwise 0/1/3h algorithm to triage patients with suspected myocardial infarction

Abstract Background In patients with suspected myocardial infarction (MI), application of 0/1h-algorithms is recommended by guidelines of the European Society of Cardiology. Depending on assay-specific changes of high-sensitivity troponin (hs-Tn), these algorithms allow for rule-in or rule-out of MI at presentation or after 1 hour (h). Yet, a relevant proportion of patients remain in the observe group at 1h in need for further diagnostic. Recently, specific cutoffs at 3h were suggested for hs-TnT, enabling an additional 3h triage option in conjunction with the 0/1h algorithm to further reduce the proportion of patients in the observe zone. Objective We aimed to externally validate the diagnostic performance of the 0/1/3h algorithm in patients with suspected MI. Methods We consecutively enrolled patients with symptoms suggestive of MI in the emergency department of a tertiary hospital in Germany. Patients with STEMI were excluded. Concentrations of hs-TnT were measured at presentation, after 1h and 3h. Final diagnoses were adjudicated by two cardiologists according to the 4th Universal Definition of MI. Applying the 0/1/3h algorithm, patients were triaged into rule-in, rule-out- and observe-group. We assessed the diagnostic performance parameters in the overall sample as well as for predefined subgroups including sex, age ≥65 vs. <65 years, glomerular filtration rate (GFR) ≥60ml/min/m² vs. <60ml/min/m², and symptom onset time <1h vs. 1-3h vs. >3h). Results In 2,514 patients (median age 64 years, 36.4% female), prevalence of NSTEMI was 14.4%. Application of the 0/1/3h algorithm ruled-out 1511 (60.1%) and ruled-in 587 (23.3%) patients. Only 416 (16.6%) remained in the observe group at 3h. Safety of rule-out was high with a sensitivity of 98.6% (95%CI 96.8%, 99.4%) and a corresponding negative predictive value of 99.7% (95%CI 99.2%, 99.9%). Rule-in performance was acceptable with a specificity of 89.3% (95%CI 87.9%, 90.5%) and positive predictive value (PPV) of 60.8% (95%CI 56.8, 64.7, Figure 1). Regarding subgroup analyses, sensitivity and NPV were marginally but statistically lower in patients with normal as compared with impaired renal function (p both <0.001). Further, specificity was substantially lower in older patients (84.8% vs. 93.3%, p<0.001), patients with GFR<60ml/min/m² (78.3% vs. 93.0%, p<0.001) as well as in male patients (88.1% vs. 91.2%, p=0.028) (Figure 2). A relevantly larger proportion of patients remained in the observe group after 3h in patients with impaired renal function (32.3% vs. 10.9%), as well as in patients aged ≥ 65 years (26.8% vs. 6.8%). Conclusion Application of the 0/1/3h algorithm in patients with suspected MI resulted in good diagnostic performance with excellent rule-out safety and moderate rule-in capacity. In patients with impaired renal function as well as elderly patients, specificity was significantly lower while observing a larger proportion of patients remaining in the observe zone at three hours.Figure 1:Diagnostic flowFigure 2:Forest Plots

Long-term administration of atorvastatin had no effect on the occurrence and progression of spontaneous hypertensive intracerebral hemorrhage in mice

Abstract Background Intracerebral hemorrhage (ICH) is a catastrophic disease with limited treatment options. Statins and low low-density lipoprotein cholesterol (LDL-C) levels have been reported to be associated with increased risk of ICH. Safety concerns of statins were raised as statins become the cornerstone of anti-atherosclerosis therapy. To date, the effect of statins on the incidence of ICH still remains a controversial topic. Purpose The aim of this study was to investigate the effect of atorvastatin on the occurrence and progression of hypertensive ICH in mice. Methods Male wild-type C57BL/6J mice, 13 months old, were randomly divided into atorvastatin (Ato, n=20) group and vehicle (Veh, n=20) group. The atorvastatin group and vehicle group were given atorvastatin (20 mg/kg) and same volume of 0.5% sodium carboxymethylcellulose by oral gavage for 8 weeks, separately. Angiotensin II (Ang II) and L-NAME were then used to induce hypertensive ICH. The time of stroke symptom onset was documented. Hemorrhage volumes were measured by spectrophotometric hemoglobin assay. Results After 8 weeks of atorvastatin or vehicle administration, serum LDL-C levels were significantly lower in the mice treated with atorvastatin than vehicle controls (0.705 vs. 1.008 mmol/L, P<0.001). The administration of atorvastatin did not show significant effects on the systolic blood pressure (SBP) levels when compared with the vehicle group (164 vs. 166 mmHg, P=0.497) after the induction of Ang II and L-NAME. Hemorrhage was observed in brain morphology, and was further verified by hematoxylin and eosin staining or MRI scans in mice that showed signs of stroke. During the 28-day experimental period, 75% (15/20) of mice in the atorvastatin group developed signs of ICH, and 70% (14/20) of mice in the vehicle group developed in the similar time window. The incidence of hypertensive ICH had no significant difference between atorvastatin and vehicle groups (Log-rank P=0.761). Hemorrhage volumes were also comparable between the two groups (1.462 vs. 1.392 uL, P=0.788). Conclusion Reducing serum LDL-C levels by long-term administration of atorvastatin had no effect on the occurrence and progression of spontaneous hypertensive ICH in middle-aged mice.

Changes in core depressive symptoms over time in peripartum women: A network analysis

Perinatal depression (PND) is a prevalent mental health condition that affects women during pregnancy and after childbirth. Distinct clinical subtypes of PND exist, with the timing of symptom onset being a pivotal element in the classification of these subtypes. However, the specific manifestations of PND across the various stages of pregnancy and the postpartum period remain to be elucidated. This study aimed to explore the changes in depression symptoms with the stage of pregnancy. Women in their second (n = 161) and third trimesters (n = 248) of pregnancy as well as those in their first 6 weeks of the postpartum period (n = 110) were recruited. Each patient was evaluated using the Edinburgh Postnatal Depression Scale. A network analysis approach was used to explore the interconnections among depressive symptoms across the different time periods. Women in the postpartum period exhibited the most pronounced prevalence of PND and severity of depressive symptoms. In the second and third trimesters, “sadness and misery” was the most central symptom. However, its prominence diminished after childbirth. “Fear and panic” was the predominant symptom in the postpartum network. The structural integrity of PND symptom networks was maintained across all three periods, with consistent strength and closeness. This study demonstrates the temporal evolution of PND’s central symptoms in women during and after pregnancy, transitioning from depression-centric to anxiety-centric manifestations. These findings advocate for symptom-specific interventions to enhance the mental well-being of mothers and their offspring. Furthermore, this study offers clinical insights into the biological underpinnings of PND subtypes, facilitating precise diagnosis and targeted treatment strategies.

Functional neurological disorder in pregnancy, labour and the postpartum period: systematic review.

Functional neurological disorder (FND) most often presents in women of childbearing age, but little is known about its course and outcomes during pregnancy, labour and postpartum (the perinatal period). We searched MEDLINE, PsycInfo and Embase combining search terms for FND and the perinatal period. We extracted data on patient demographics, subtype of FND, timing of symptom onset, comorbidities, medications, type of delivery, investigations, treatment, pregnancy outcomes and FND symptoms at follow-up. We included 36 studies (34 case reports and 2 case series) describing 43 patients. Six subtypes of FND were identified: functional (dissociative) seizures, motor weakness, movement disorder, dissociative amnesia, speech disorders and visual symptoms. New onset of perinatal FND was more common in the third trimester and onwards. Some women with functional seizures were exposed to unnecessary anti-seizure prescriptions and intensive care admissions. Prospective studies are urgently needed to explore how FND interacts with women's health in the perinatal period.

Analysis of laboratory and instrumental data in young patients with COVID-19 and cardiovascular disorders

Introduction. Despite significant information on cardiovascular damage in older patients with COVID- 19, there is no clear understanding of the variability of cardiac diseases manifestations in young patients. Additionally, summarized data characterizing the severity of myocardial damage in these patients is lacking.Aim. To compare laboratory and functional study data and identify predictors of cardiovascular damage in young patients with COVID-19.Materials and methods. An analysis of 4,453 medical records from 2020 to 2022 was conducted. The focus was on patient age (18- 44 years), primary diagnosis, severity of COVID-19, comorbid conditions, timing of cardiovascular symptom onset, and laboratory and functional study data characterizing cardiovascular system damage. According to the inclusion and exclusion criteria, 132 medical records of patients aged 18 to 44 years with moderate COVID-19 were selected, including 49 with cardiovascular issues and 83 without cardiovascular pathology.Results. Comparative analysis showed that cardiovascular system damage in young patients with moderate COVID-19, compared to those without cardiovascular pathology, was associated with elevated levels of C-reactive protein (CRP) (p=0.001), brain natriuretic peptide (NTproBNP) (p<0.0001), D-dimer (p<0.0001), and troponin I (p<0.0001). CRP levels in patients with pericarditis and acute myocardial infarction (AMI) were higher than in those with acute cerebrovascular accident (ACVA) (p=0.001). No differences in D-dimer levels were found between subgroups (p>0.05). Troponin I and NTproBNP levels in the AMI subgroup were higher than in the pericarditis (p<0.0001 and p=0.047, respectively) and ACVA (p=0.001 and p=0.043, respectively) subgroups. Patients with cardiovascular disorders had a reduced left ventricular ejection fraction (LVEF) (p=0.005) without significant changes in left ventricular end-systolic (p=0.200) and end-diastolic volumes (p=0.119). The lowest LVEF was found in the AMI and ACVA subgroups (p=0.001). Correlation-regression analysis revealed associations between cardiovascular complications and NTproBNP (r=0.673, p<0.001), troponin I (r=0.543, p<0.001), and D-dimer (r=0.363, p<0.001), as well as LVEF (r=-0.341, p<0.001). Significant stochastic relationships were also found between D-dimer and troponin I (r=0.532, p<0.001), NTproBNP (r=0.545, p<0.001); and between LVEF and troponin I (r=-0.420, p<0.001), NTproBNP (r=-0.314, p<0.001). Multivariate regression analysis showed that NTproBNP, with a sensitivity of 86.5% and specificity of 81.9%, is an independent predictor of cardiovascular complications in young patients with moderate COVID-19 (OR=1.175, p=0.001).Conclusion. The results indicate that the severity of COVID-19, regardless of patient age and comorbidities, can be a factor in the development of cardiovascular complications. NTproBNP levels in the blood of COVID-19 patients can be an early marker of cardiovascular risk. However, further research is needed to confirm the pathogenetic role of cardiotropic protein in the development of pericarditis, AMI, and ACVA in these patients.

Ethion food poisoning outbreak in Pereira, Colombia, 2022

Introduction Ethion is an organophosphate used as an acaricide and insecticide, that is restricted worldwide. In Colombia, pesticide poisoning is the third most common cause of chemical intoxication. On 9 October 2022, an outbreak of ethion poisoning occurred in Pereira. The aim of this study was to describe the clinical and epidemiological characteristics of the outbreak. Methods This is a descriptive study of an outbreak of organophosphate poisoning. The onset of symptoms occurred on 9 October 2022, following the consumption of empanadas. Information was collected on sociodemographic characteristics and clinical manifestations, as well as from paraclinical examinations. Data were obtained from clinical histories, field epidemiological investigations, and inspection visits. Food samples were collected for analysis by gas chromatography-mass spectrometry. Attack rates, proportions, and measures of central tendency, dispersion, and position were calculated. Results The case definition was met by 37 individuals with a median age of 30 years; all presented with muscarinic symptoms, 29 patients presented with nicotinic symptoms, and 20 patients presented with neurological symptoms. Males were the most affected (57%), and the most common time of symptom onset was 10:00 am. Twenty-three patients (62%) required intensive care unit admission, of whom 14 (38%) required mechanical ventilation. No deaths were reported. Erythrocyte acetylcholinesterase activity was reduced in all patients. Ethion was detected in mass-prepared maize and empanadas at concentrations greater than 0.1 mg/kg. The consumption of empanadas was identified as the common source. Discussion In Colombia, pesticide poisonings are the third most common type of poisoning caused by chemical substances reported to the National Health Institute through the National Public Health Surveillance System. In the present outbreak, ethion was in empanadas, likely due to contamination of cooking oil. Conclusions We describe a large ethion-contaminated food poisoning outbreak reported in Colombia. The main symptoms were muscarinic, and the main treatment measures employed were atropine and respiratory support. Increased awareness of pesticide poisoning and training for food handlers are needed.

Knowledge, attitude and behaviour around concussion at the FIFA Women’s World Cup 2023: part 2 – coaches, performance staff and players

ABSTRACT The objective of this observational cross-sectional study was to assess the knowledge, attitude and behaviour of coaches and performance staff (i.e. ‘coaching staff’), and players from the 32 teams qualified for the FIFA Women’s World Cup 2023 regarding assessment and management of concussion in football. Two online surveys were developed: 1) coaching staff, and 2) players. The results were analysed descriptively. Eighty-four coaching staff and 229 players completed the survey. Concussion knowledge: 39% of coaching staff and 33% of players were aware of concussion protocol(s). Knowledge: concussion symptom onset time was correctly reported by 18% of coaching staff and 11% of players. Knowledge about risks related to sustaining a concussion or returning to play too soon varied in both groups. Attitude: 26% of coaching staff and 31% of players reported being very confident or confident in recognizing a suspected concussion. Half of the players (52%) reported to always report symptoms of concussion if feeling any. One (1%) member of the coaching staff and 24 (10%) players reported feeling that a player can return to play with mild symptoms after a concussion. Behaviour: Most coaching staff reported they would have supportive behaviour if faced with a suspected concussion on the pitch. Among players, 64% stated that they would leave the assessment to their team’s medical staff, and 4% would encourage their teammates to keep playing. In conclusion, coaching staff and players showed limited knowledge about concussion. Most coaching staff reported attitudes and intended behaviour towards protecting players’ health; whilst players' responses varied.

Accuracy of the Dual Path Platform (DPP) rapid test for the diagnosis of leptospirosis: A multi-center study in six Brazilian states

Leptospirosis is a zoonotic disease with significant global impact and a challenging diagnosis. The utilization of adequately validated rapid tests is relevant for the opportune identification of the disease and for reduction in fatality rates. The present study analyzes the accuracy and reliability of the Dual Path Platform (DPP) assay -produced in Brazil by the Oswaldo Cruz Foundation (Fiocruz)- for diagnosing leptospirosis. Firstly, a serological panel was constructed in the Brazilian Reference Laboratory for Leptospirosis using samples routinely handled by reference laboratories of six Brazilian states. It consisted of 150 positive (according to MAT and IgM-ELISA) and 250 negative samples for leptospirosis. Subsequently, the panel samples were distributed to the reference laboratories for the performance of DPP assays in triplicate. Different measures were used in the assessment of diagnostic quality. Predictive values were estimated for different pre-test probability settings. Sensitivities varied between 67.33 % and 74.00 % and specificities between 93.20 % and 98.40 % in the states, and there were adequate agreements between them. Accuracies were lower for the samples of patients with less than 7 days of symptoms. In contexts of prevalence values up to around 25 %, positive and negative predictive values were around 90 %. However, in situations of high pre-test probabilities, NPVs were low. This study improves understanding of the use of DPP in diagnosing leptospirosis, particularly its application in healthcare settings. As long as the time of symptoms onset and clinical and epidemiological contexts are adequately considered for the interpretation of results, DPP is a valid option to be used in the leptospirosis diagnostic routine.

Knowledge, attitude, and behaviour around concussion at the FIFA Women's World Cup 2023: part 1 - medical staff.

The objective of this observational cross-sectional study was to assess the knowledge, attitudes and behaviours of medical staff participating in the FIFA Women's World Cup 2023 regarding the assessment and management of concussion in football. Medical staff from 32 teams qualified for the FIFA Women's World Cup 2023 were invited to answer an online survey. Results were analysed descriptively. 47 participants completed the survey. Concussion knowledge: 98% were aware of concussion protocol(s). Most concussive signs or symptoms were recognised, though only 36% of participants (n = 17) correctly reported potential symptom onset time. Knowledge on assessment and return to play elements varied. Attitude: 77% (n = 36) reported being very confident or confident in recognizing a suspected concussion. When assessing a suspected concussion on the pitch, 55% (n = 26) reported to have felt pressured by the player sometimes, very often or always, and 47% (n = 22) by the coaching staff. Behaviour: Among doctors, 70% reported their national team performs baseline concussion assessments. Reported use of on-field assessment elements suggested in concussion guidelines varied between 5% and 95%. In conclusion, most medical staff participating in the FIFA Women's World Cup 2023 were generally knowledgeable about concussion, reported on-pitch and return to play attitudes and behaviours aligning with evidence-based standards for safeguarding players' health. However, gaps were observed in all three domains, compared to guidelines. Expanding education to players and coaching staff is suggested to facilitate the delivery of evidence-based best practice.

Dermatologic manifestations of patients with severe and non-severe COVID-19 infection: A cross-sectional study

Introduction: Since the emergence of COVID-19 in late 2019, multiple concerns have been raised regarding the unknown nature of the disease, including dermatologic complications. In this study, we discussed dermatologic manifestations of patients with COVID-19 infection who visited our clinic. Methods: Eighty- six patients were involved based on our inclusion and exclusion criteria (50 female and 36 male). All patients with definite diagnosis of COVID-19 who were referred to our dermatologic clinic were enrolled in this cross-sectional study. Only lesions which occurred 1 week prior to or 3 months after first COVID-19 symptoms were included. The photographs of all lesions were independently reviewed by four experienced dermatologists and an infectious disease specialist to reach the objectives stated above. Qualitative data presented as frequency (%) and compared using chi-squared or Fisher’s exact test, and quantitative data presented as mean±SD or median (IQR) based on normality, with P value≤0.05 considered statistically significant. Results: Eighty- six patients were enrolled in the study (mean±SD age=36.95±17.78). Eighteen specific types of dermatologic complications were seen. The most common lesions included maculopapular rash and scalp hair loss. The only lesions with a statistically significant difference regarding COVID-19 symptom onset time were maculopapular rash, telogen effluvium, and papular urticaria. The only lesions with statistically significant difference regarding COVID-19 severity were maculopapular rash, telogen effluvium, and urticaria. Conclusion: Our study revealed that a wide range of skin lesions may occur in patients with COVID-19. We found a statistically significant relation between disease severity and certain dermatologic manifestations.

Racial Disparities in the Diagnosis and Prognosis of ALS Patients in the United States.

Amyotrophic lateral sclerosis (ALS) is a progressive, fatal disease with largely unknown etiology. This study compares racial differences in clinical characteristics of ALS patients enrolled in the National ALS Registry (Registry). Data from ALS patients who completed the Registry's online clinical survey during 2013-2022 were analyzed to determine characteristics such as site of onset, associated symptoms, time of symptom onset to diagnosis, and pharmacological and non-pharmacological interventions for White, Black, and other race patients. Surveys were completed by 4242 participants. Findings revealed that Black ALS patients were more likely to be diagnosed at a younger age, to have arm or hand initial site of onset, and to experience pneumonia than were White ALS patients. ALS patients of other races were more likely than White ALS patients to be diagnosed at a younger age and to experience twitching. The mean interval between the first sign of weakness and an ALS diagnosis for Black patients was almost 24months, statistically greater than that of White (p = 0.0374; 16months) and other race patients (p = 0.0518; 15.8months). The mean interval between problems with speech until diagnosis was shorter for White patients (6.3months) than for Black patients (17.7months) and other race patients (14.8months). Registry data shows racial disparities still exist in the diagnosis and clinical characteristics of ALS patients. Increased recruitment of non-White ALS patients and better characterization of symptom onset between races might aid clinicians in diagnosing ALS sooner, leading to earlier therapeutic interventions.

Outcomes of Covid-19 Vaccine-Associated Glomerular Diseases (CVAGD) – A Case Series from India

Background Several cases of glomerular diseases following Covid-19 vaccination, especially mRNA vaccines, have been reported. However, there is little data on glomerular diseases associated with the two vaccines widely available in India (Covaxin and Covishield) and their long-term outcomes. Materials and Methods This was a prospective observational study conducted between May 2021 and May 2023. Patients with new-onset or relapse of proteinuria, hematuria, or renal failure within 30 days of Covid-19 vaccination were included. Data on pre-existing renal disease, vaccine type, symptomatology, laboratory reports, kidney biopsy findings, and treatment details were collected. The clinical course and long-term renal outcomes were studied. Results Sixteen patients with Covid-19 vaccine associated glomerular disease (CVAGD) were studied. The median age was 28 years (IQR 20.5–40) and median time of symptom onset was 14 days (IQR 10–16.5) after vaccination. Renal syndromes at presentation were nephrotic syndrome in seven patients (43.75%), nephritic syndrome in seven patients (43.75%), and rapidly progressive renal failure in two patients (12.5%). Kidney biopsy revealed minimal change disease in five patients (31.2%); IgA nephropathy in four patients (25%); C3 glomerulopathy, lupus nephritis, and focal segmental glomerulosclerosis in two patients each (12.5%); and pauci-immune glomerulonephritis (ANCA-associated vasculitis) in one patient (6.25%). Eleven patients were treated with immunosuppressive drugs. Median duration of follow-up was 20 months (IQR 18–21). At last follow-up, 11 patients had complete recovery of renal failure and proteinuria and 4 patients had partial recovery. Conclusion The most common lesions in this series were minimal change disease and IgA nephropathy. The overall long-term outcome of CVAGD appears good.

Flexible Bayesian estimation of incubation times.

The incubation period is of paramount importance in infectious disease epidemiology as it informs about the transmission potential of a pathogenic organism and helps to plan public health strategies to keep an epidemic outbreak under control. Estimation of the incubation period distribution from reported exposure times and symptom onset times is challenging as the underlying data is coarse. We develop a new Bayesian methodology using Laplacian-P-splines that provides a semi-parametric estimation of the incubation density based on a Langevinized Gibbs sampler. A finite mixture density smoother informs a set of parametric distributions via moment matching and an information criterion arbitrates between competing candidates. Algorithms underlying our method find a natural nest within the EpiLPS package, which has been extended to cover estimation of incubation times. Various simulation scenarios accounting for different levels of data coarseness are considered with encouraging results. Applications to real data on COVID-19, MERS and Mpox reveal results that are in alignment with what has been obtained in recent studies. The proposed flexible approach is an interesting alternative to classic Bayesian parametric methods for estimation of the incubation distribution.

Comparison of Demographics: National Amyotrophic Lateral Sclerosis Registry and Clinical Trials Data.

To characterize the participant demographics in the Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) database compared with the web-portal National Amyotrophic Lateral Sclerosis (ALS) Registry (the Registry). Demographics and ALS symptom information were compared between the self-reported registrant data in the Registry web portal (2010-2021) and the latest available PRO-ACT data (updated August 2022), which is a collection of clinical trials data. Greater percentages of younger (≤ 59years old) but smaller percentages of older (60 + years old) participants were represented in PRO-ACT compared to Registry. Enrollment for minority race groups was greater in the Registry portal data, but race information was largely missing/unknown in PRO-ACT database. Median age at the time of diagnosis and age at the time of symptom onset were significantly higher for Registry enrollees compared to the participants of PRO-ACT. Symptom onset sites were similarly reported, but duration between self-noted symptom onset and diagnosis was slight, but significantly longer for the Registry enrollees (11 vs. 9months). Hispanic were as likely as non-Hispanic to participate in research studies, based on the Registry data. There was a notable difference in the age distribution and minority representation of enrollees between the PRO-ACT and Registry study populations. Age distribution in the PRO-ACT database skewed to a younger and less diverse cohort. Despite the clinical heterogeneity and complex disease mechanism of ALS, identifying the underrepresented demographic niche in the PRO-ACT and Registry study populations can help improve patient participation and criteria for patient selection to enhance generalizability.

Acute Basilar Artery Tip Thrombosis Presenting as Basilar-Subclavian Steal Phenomenon on Transcranial Doppler

Acute basilar artery (BA) occlusion is a key etiology of devastating posterior circulation stroke, unless recanalization is performed early. Recanalization therapy is determined synthetically based on symptom onset time, stroke severity, and brain imaging. Herein, we report the case of a 72-year-old male patient presenting with minor neurological symptoms, but with thrombotic occlusion at the BA tip. Transcranial Doppler (TCD) showed systolic flow reversal along the vertebrobasilar arteries, and the patient benefited from endovascular thrombectomy. This case highlights the critical role of TCD in identifying hemodynamic insufficiency and determining the implementation of endovascular interventions to mitigate stroke progression.

One- and Two-year Multidisciplinary Follow-Up of MIS-C at a Tertiary Hospital: A Retrospective Cohort Study.

Although 6-month follow-up of patients with multisystem inflammatory syndrome in children (MIS-C) was reassuring, there is scant data on long-term sequelae, including whether changing variants affect clinical severity and outcomes. Children (<18 years of age) admitted to Great Ormond Street Hospital between April 4, 2020, and January 2023, meeting diagnostic criteria for MIS-C were included. Admission and follow-up data were categorized by the predominant SARS-CoV-2 circulating variant in the United Kingdom. One hundred and sixty children [median age, 10.1 (interquartile range, 7.9-12.6) years] were included. There was no difference in the time of symptom onset to diagnosis between waves ( P =0.23) or hospitalization days across all waves ( P =0.32). Inflammatory markers were normal for up to 2 years in all patients except one. Eleven patients (6.9%) remain in follow-up: cardiology (n=5), gastroenterology (n=5) and nephrology (n=1). The main self-reported symptoms at 2 years were abdominal pain (n=5) and myalgia (n=2). Fatigue was present in approximately a quarter of patients at admission; this reduced to 14 (9%), (2%) and 1 (2%) at 6-month, 1-year and 2-year follow-ups, respectively. Chronic fatigue or long-COVID symptomatology was rare (n=1) even with high rates of concurrent Epstein-Barr virus positivity (49/134). All patients had sustained neurological recovery with no new neurological pathology observed. Patients with MIS-C have a sustained recovery, which is reassuring for positive long-term outcomes. Across waves, time from symptom onset to diagnosis and treatment, symptomatology and length of stay were similar. Sustained recovery is reassuring for clinicians and parents alike. Differentiating long-COVID symptomatology from that of MIS-C is important in formulating an individualized treatment plan.

Increased ERCP-related adverse event from premature urgent ERCP following symptom onset in acute biliary pancreatitis with cholangitis

Acute biliary pancreatitis (ABP) with cholangitis requires endoscopic retrograde cholangiopancreatography (ERCP) within 24 h to resolve ductal obstruction. However, this recommendation is based on the timing of emergency room (ER) visits. We wanted to determine the optimal timing of ERCP for ABP based on the timing of symptom onset, not the timing of the ER visit. We retrospectively reviewed 162 patients with ABP with cholangitis who underwent urgent ERCP (within 24 h of ER admission). Area under the receiver operating characteristic (ROC) curve (AUC) was analyzed to determine differences in complication rates according to time from symptom onset. A difference in ERCP-related adverse events (AEs) was identified, and Youden’s J statistic was used to determine a cutoff time from symptom onset (18 h). We compared mortality and complications based on this cutoff. Based on time to symptom onset, significantly higher rates of aspiration pneumonia (odds ratio [OR] 4.00, 95% confidence interval [CI] 1.15–13.92, P = 0.021) and post-ERCP hypotension (OR 11.9, 95% CI 1.39–101.33, P = 0.005) were observed in the ≤ 18-h group than in the > 18-h group. The study found that patients who underwent ERCP within 18 h of symptom onset is associated with an increased risk of ERCP-related AEs.
