Impact of race and socioeconomic deprivation on clinical outcomes and healthcare utilization in pediatric multiple sclerosis.

Health disparities in adult-onset multiple sclerosis have been identified in the Black/African American (AA) population. A higher relapse rate has been suggested in Black/AA patients with pediatric-onset MS (POMS), but little work explores healthcare utilization and social determinants of health (SDOH). To evaluate racial, ethnic, and socioeconomic disparities in POMS outcomes. Retrospective chart review identified 31 eligible patients diagnosed with POMS at Children's of Alabama between 2013 and 2023. Demographics, outcomes, and healthcare utilization over 2 years from diagnosis were collected. Patient addresses were connected to SDOH measures from the US Census. Bivariate analysis was performed using Fisher's Exact Test, Wilcoxin Test, and 2-sided t-test. Black/AA children had a higher Expanded Disability Status Scale (EDSS) at first presentation (p = 0.0276) and were more likely to initiate fingolimod vs. glatiramer acetate (p = 0.0464). Living further from Children's of Alabama was associated with a higher most recent EDSS (p = 0.0301) and fewer neurology appointments (p = 0.0167). Families living in more socioeconomically deprived census tracts had significantly more hospital admissions. Black/AA POMS patients had a more severe initial presentation and were started on higher efficacy medication. We identified disparities in EDSS and healthcare utilization based on SDOH data linked to a child's home address.

Lower admission stroke severity is associated with good collateral status in distal medium vessel occlusion stroke.

Distal medium vessel occlusions (DMVOs) are a significant contributor to acute ischemic stroke (AIS), with collateral status (CS) playing a pivotal role in modulating ischemic damage progression. We aimed to explore baseline characteristics associated with CS in AIS-DMVO. This retrospective analysis of a prospectively collected database enrolled 130 AIS-DMVO patients from two comprehensive stroke centers. Baseline characteristics, including patient demographics, admission National Institutes of Health Stroke Scale (NIHSS) score, admission Los Angeles Motor Scale (LAMS) score, and co-morbidities, including hypertension, hyperlipidemia, diabetes, coronary artery disease, atrial fibrillation, and history of transient ischemic attack or stroke, were collected. The analysis was dichotomized to good CS, reflected by hypoperfusion index ratio (HIR) <.3, versus poor CS, reflected by HIR ≥.3. Good CS was observed in 34% of the patients. As to the occluded location, 43.8% occurred in proximal M2, 16.9% in mid M2, 35.4% in more distal middle cerebral artery, and 3.8% in distal anterior cerebral artery. In multivariate logistic analysis, a lower NIHSS score and a lower LAMS score were both independently associated with a good CS (odds ratio [OR]: 0.88, 95% confidence interval [CI]: 0.82-0.95, p<.001 and OR: 0.77, 95% CI: 0.62-0.96, p=.018, respectively). Patients with poor CS were more likely to manifest as moderate to severe stroke (29.1% vs. 4.5%, p<.001), while patients with good CS had a significantly higher chance of having a minor stroke clinically (40.9% vs. 12.8%, p<.001). CS remains an important determinant in the severity of AIS-DMVO. Collateral enhancement strategies may be a worthwhile pursuit in AIS-DMVO patients with more severe initial stroke presentation, which can be swiftly identified by the concise LAMS and serves as a proxy for underlying poor CS.

Comparison of radiological and clinical characteristics of COVID-19 positive and negative ischemic stroke patients undergoing revascularization: A single-centre Turkish study

ObjectiveWe aimed to compare the radiological and clinical characteristics of COVID-19-positive and -negative acute ischemic stroke (AIS) patients who underwent revascularization and to evaluate whether COVID-19 has an effect on revascularization and outcome in AIS patients with COVID-19 infection. MethodsConsecutive COVID-19 positive and negative AIS patients who underwent intravenous thrombolysis and/or endovascular therapy in our hospital between March 2020 and February 2022 were included in this study. Our study is retrospective and 23 COVID-19 positive patients and 108 COVID-19 negative patients were compared in terms of radiological and clinical characteristics. ResultsHypertension was lower in the COVID-19 positive ischemic stroke group (p=0.029). Admission NIHSS score was higher in COVID-19 positive patients (p=0.041). ASPECTS was found to be lower in COVID-19 positive ischemic stroke patients (p=0.019). The rate of hyperdense artery sign differed between groups (p=0.014) and was higher in the COVID-19 positive ischemic stroke group. The incidence of multi-vessel occlusion was found to be significantly higher in the COVID-19-positive ischemic stroke group (p=0.002). In terms of prognostic features, only the 3-month good outcome rate was statistically significantly lower in the COVID-19-positive ischemic stroke group (p=0.011). ConclusionThis study found that radiologically, COVID-19 may be associated with lower ASPECTS in ischemic stroke patients receiving revascularization treatment and may predispose to multivessel occlusion and hyperdense artery sign. Clinically, COVID-19 may be associated with a more severe initial presentation and worse prognosis at 3 months in ischemic stroke patients undergoing revascularization, but may not affect long-term mortality.

Mortality in adolescents and young adults following a first presentation to the emergency department for alcohol.

We conducted a population-based, retrospective cohort study of first-time emergency department (ED) visits in adolescents and young adults (AYA) due to alcohol and compared mortality to AYA with nonalcohol ED visits between 2009 and 2015 using standardized all-cause mortality ratios (age, sex, income, and rurality). We described the cause of death for AYA and examined the association between clinical factors and mortality rates in the alcohol cohort using proportional hazard models. A total of 71,776 AYA had a first-time ED visit due to alcohol (56.1% male, mean age 20.7 years) between 2009 and 2015, representing 3.3% of the 2,166,838 AYA with an ED visit in this time period. At 1 year, there were 2396 deaths, 248 (10.3%) following an ED visit related to alcohol. First-time alcohol ED visits were associated with a threefold higher risk in mortality at 1 year (0.35% vs. 0.10%, adjusted hazard ratio [aHR] 3.07, 95% confidence interval [CI] 2.69-3.51). Mortality was associated with age 25-29 years (aHR 3.88, 95% CI 2.56-5.86), being male (aHR 1.98, 95% CI 1.49-2.62), having a history of mental health or substance use (aHR 3.22, 95% CI 1.64-6.32), cause of visit being withdrawal/dependence (aHR 2.81, 95% CI 1.96-4.02), and having recurrent ED visits (aHR 1.97, 95% CI 1.27-3.05). Trauma (42.7%), followed by poisonings from drugs other than opioids (38.3%), and alcohol (28.6%) were the most common contributing causes of death. Incident ED visits due to alcohol in AYA are associated with a high risk of 1-year mortality, especially in young adults, those with concurrent mental health or substance use disorders, and those with a more severe initial presentation. These findings may help inform the need and urgency for follow-up care in this population.

Characteristics, risk factors and outcomes of patients managed for left-sided infective endocarditis: a prospective study in a high-volume center

Abstract Background Although medical and surgical management of infective endocarditis (IE) have improved in the recent decades, the associated mortality remains high. Available prospective data are scarce, and further knowledge from prospective cohorts could help improving the prognosis of patients with IE. Objective To describe the characteristics and outcomes of left-sided IE and to determine the risk factors associated to in-hospital mortality in a high-volume center. Methods From 15 September 2020 to 15 February 2023, all patients with left-sided IE managed in a tertiary center of cardiology were included in this prospective, observational study. The diagnosis of IE was made according to current guidelines and management was collegially discussed by the endocarditis team. Determinants of in-hospital death were assessed using a multivariate logistic regression model including any covariate associated in univariate analysis (p&amp;lt;0.1). Results A total of 185 patients were included during the study period. Median age was 68 [56 – 76] years, 141 (76%) patients were males, and 75 (41%) cases involved a prosthetic valve. Aortic valve, mitral valve and involvement of both valves were observed in 111 (60%), 48 (26%) and 26 (14%) patients, respectively. Multimodal cardiac imaging, including cardiac computed tomography (CT) and/or PET-FDG, was used in 64 (35%) of all cases, and 49/75 (65%) patients with valvular prosthesis. Severe valvular regurgitation was identified in 56 (30%) patients, root abscess and/or false aneurysms in 57 (31%) patients. A pathogen agent was identified in 169 (91%) patients, and the most frequent germs were Staphylococcus (30%), Streptococcus (30%) and Enterococcus (17%). A severe initial presentation requiring intensive care unit (ICU) admission was observed in 42 (23%) patients. Cardiac surgery was performed in 102 (55%) cases, and 41 (22%) patients required an emergent surgery. A total of 37 (20%) patients died during the initial in-hospital phase, mostly from cardiac or neurovascular causes. In a multivariate analysis, hypertension (Odd ratio (OR) = 3.3; 95% confidence interval (CI): 1.4 – 10), bi-valvular endocarditis (OR = 3.1; 95%CI: 1.0 – 9.5), unidentified pathogen (OR = 4.3; 95%CI: 1.7 – 15) and chronic alcoholic abuse (OR = 16.4; 95%CI: 3.7 – 87.9) were independently associated with increased in-hospital mortality (Table). Conclusion Severe initial presentation requiring an ICU admission and/or urgent cardiac surgery was common among patients with left-sided IE. Chronic alcoholic abuse and unidentified pathogen appear as major determinants of in-hospital mortality.Table

1744. Association Between Antibiotic Prescribing for Urinary Tract Infection (UTI) and UTI Severity of Illness Upon Admission to Hospitals in New York State

Abstract Background It has been previously demonstrated that county-level antibiotic prescribing (CP) and resistance (AR) influence urinary tract infection (UTI) severity of illness upon hospital presentation in New York State (NYS, Grillo et al. IDWEEK 2021). However, previous investigations were geographically limited to the most densely populated regions of NYS. This study builds on the previous study by evaluating additional NYS regions and outcomes. Methods Retrospective, cross-sectional study, combining data from NYS Statewide Planning and Research Cooperative System (SPARCS) and previously published data on CP for UTI in female Medicare beneficiaries. Eligibility criteria: female patients admitted to a NYS inpatient setting in 2017, UTI (CCS 159), Medicare insurance. New York county (Manhattan) county was excluded. CP was the primary exposure. “Low” or “high” CP was based on the statewide median. Severe infection (All-patient refined severity of illness on admission ≥ 3, SI) was the primary outcome. Association between CP and SI, hospitalization costs, were evaluated using chi-square, logistic regression, Mann-Whitney U test. Log-rank test assessed time to discharge, censoring those that went to hospice or died inpatient. Results 13,173 patients were included, 4,250 (32.3%) low CP, 8,923 (67.7%) high CP. Baseline demographics (Figure 1) that differed between groups included age, race, ethnicity, and emergency admission (P &amp;lt; 0.001, χ2 test). In the multivariable logistic regression analysis low CP was associated with increased odds for severe urinary tract infection after adjusting for potential confounders (aOR: 1.08 [1.003 – 1.163]). Additional factors associated with severe infection are presented in Figure 2. Median (IQR) hospital costs were similar but statistically significantly lower in the low CP group (Figure 3), median (IQR) time to hospital discharge was 4 days in each group (P &amp;lt; 0.001). Figure 1.Adjusted Odds Ratios for Severe Urinary Tract InfectionFigure 2.Hospital Costs Conclusion Low CP may be a risk factor for severe initial presentation to the hospital in UTI. Further research is needed to examine the effects of prescribing patterns and additional factors that may influence severity of infection in this setting.

Common peripheral nerve entrapments in the upper limb.

Entrapment of peripheral nerves can occur as they travel through restrictive spaces. This nerve compression can result in a constellation of signs and symptoms, which are often called syndromes. Patients initially report pain, paraesthesia and numbness, followed by weakness and clumsiness and, ultimately, muscle wasting. The specific region of paraesthesia and pain and the specific muscle weakness is determined by the peripheral nerve involved and the location of the entrapment. Diagnosis is mainly based on history and examination. Further investigations are available for atypical presentations. Each syndrome has its own set of risk factors, but repetitive action and muscle overuse are commonly associated with most syndromes. The treatment is activity modification followed by steroid injection and finally surgical decompression for ongoing persistent symptoms or severe initial presentation. This article outlines the history, examination, possible investigations and management for common peripheral nerve entrapments of the median, ulnar and radial nerves.

Case Report – Successful Thrombectomy After Critical Resuscitation Following a Cardiac Arrest

Sparse evidence exists to support a delayed attempt at thrombectomy after a periprocedural cardiac arrest or acute medical decompensation. This case highlights the presentation of a 23‐year‐old woman with dilated cardiomyopathy, who initially presented with a left middle cerebral artery stroke syndrome, but who had a cardiac arrest in the angiogram suite prior to the procedure starting. After aggressive resuscitation in the critical care unit, repeat imaging showed a persistent perfusion deficit in the left middle cerebral artery territory and she successfully underwent a thrombectomy. The case highlights that critical care efforts, even after a severe initial presentation, and significant resuscitative efforts in the intensive care unit setting, can still lead to a successful thrombectomy, and that eligibility for thrombectomy can be reassessed as the patient stabilizes.

Long COVID 1 year after hospitalisation for COVID-19: a prospective bicentric cohort study.

AIMS OF THE STUDY: There is increasing interest in better understanding of long COVID, a condition characterised by long-term sequelae — appearing or persisting after the typical convalescence period — of coronavirus disease 2019 (COVID-19). Herein, we describe long-term outcomes regarding residual symptoms and psychological distress in hospitalised patients 1 year after COVID-19. METHODS: This prospective cohort study included consecutive adult patients hospitalised for confirmed COVID-19 in two Swiss tertiary-care hospitals between March and June 2020. The primary endpoint was evidence of long COVID 1 year after discharge, defined as ≥1 persisting or new symptom related to COVID-19, from a predefined list of symptoms. Secondary endpoints included psychological distress and symptoms of post-traumatic stress disorder (PTSD). RESULTS: Among 90 patients included in the study, 63 (70%) had symptoms of long COVID 1 year after hospitalisation, particularly fatigue (46%), concentration difficulties (31%), shortness of breath (21%) and post-exertion malaise (20%). Three predictors, namely duration of hospitalisation (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.00–1.22; p = 0.041), severity of illness (OR 1.19, 95% CI 1.04–1.37; p = 0.013), and self-perceived overall health status 30 days after hospitalisation (OR 0.97, 95% CI 0.94–1.00; p = 0.027) were associated with long COVID. Regarding secondary endpoints, 16 (18%) experienced psychological distress and 3 (3.3%) patients had symptoms of PTSD. CONCLUSION: A high proportion of COVID-19 patients report symptoms of long COVID 1 year after hospitalisation, which negatively affects their quality of life. The most important risk factors were severe initial presentation of COVID-19 with long hospital stays.

Women of reproductive age in a tertiary intensive care unit: indications, outcome and the impact of pregnancy\u2014a retrospective cohort study

BackgroundTo evaluate the indications for admission and mortality rates of women of reproductive age admitted to a tertiary Intensive Care Unit (ICU) and to compare the outcomes of obstetric and non-obstetric admissions.Methods A retrospective cohort study was performed, including all women aged 17–41 years admitted to a level 3 ICU in the Netherlands, between January 1, 2000 and January 1, 2016. Primary outcome was indication for admission and mortality. Mortality, length of stay (LOS), need for mechanical ventilation and APACHE II score were compared between obstetric and non-obstetric admissions. The obstetric group was further analyzed for maternal and perinatal outcomes.Results3461 women (median age 32 years) were included, with an overall mortality rate of 13.3%. The obstetric group consisted of 265 women (7.7%). The non-obstetric group (n = 3196) was admitted most often for cardiovascular disease (19.6%), followed by oncologic disease (15%). Mortality was the highest in women with oncologic disease (23.9%). The obstetric group had lower mortality compared to the non-obstetric group (4.9% vs. 14%, p < 0.001), despite higher APACHE II score (14 vs. 11, p < 0.001) and a higher ventilation rate (47.9% vs. 39%, p = 0.004). Major surgical or endovascular interventions, besides caesarean section, were performed in 46% of the obstetric group. Perinatal death occurred in 17.2% and of the surviving infants, 63.2% were born preterm and 45.1% required Neonatal Intensive Care Unit admission.ConclusionsCardiovascular disease is the most important indication for admission and oncologic disease is associated with highest mortality in women of reproductive age. Obstetric patients constitute a small percentage of all ICU admissions in a tertiary ICU center. They have lower mortality rates than non-obstetric young female patients, despite a more severe initial presentation. Nevertheless lasting maternal morbidity and perinatal mortality and morbidity is frequent.

COVID-19 and Atrial Fibrillation in Older Patients: Does Oral Anticoagulant Therapy Provide a Survival Benefit?-An Insight from the GeroCovid Registry.

Atrial fibrillation (AF), the most frequent arrhythmia of older patients, associates with serious thromboembolic complications and high mortality. Coronavirus disease 2019 (COVID-19) severely affects aged subjects, determining an important prothrombotic status. The aim of this study was to evaluate mortality-related factors in older AF patients with COVID-19. Between March and June 2020, we enrolled ≥60 year-old in-hospital COVID-19 patients (n = 806) in GeroCovid, a multicenter observational study promoted by the Italian Society of Gerontology and Geriatric Medicine. The prevalence of AF was 21.8%. In-hospital mortality was higher in the AF group (36.9 vs. 27.5%, p = 0.015). At admission, 51.7, 10.2, and 38.1% of AF cases were taking, respectively, oral anticoagulants (OACs), antiplatelet agents, and no antithrombotic therapy. During hospitalization, 51% patients switched to low-molecular-weight heparins. AF patients who survived were younger (81 ± 8 vs. 84 ± 7 years; p = 0.002) and had a lower CHA2DS2-VASc score (3.9 ± 1.6 vs. 4.4 ± 1.3; p = 0.02) than those who died. OAC use before (63.1 vs. 32.3%; p < 0.001) and during hospitalization (34.0 vs. 12.7%; p = 0.002) was higher among survivors. At multivariable analysis, lower age, higher self-sufficiency, less severe initial COVID-19 presentation, and the use of vitamin K antagonists (odds ratio [OR] = 0.16, 95% confidence interval [CI]: 0.03-0.84) or direct OACs (OR = 0.22, 95% CI: 0.08-0.56) at admission, or the persistence of OAC during hospitalization (OR = 0.05, 95% CI: 0.01-0.24), were associated with a lower chance of in-hospital death. AF is a prevalent and severe condition in older COVID-19 patients. Advanced age, dependency, and relevant clinical manifestations of disease characterized a worse prognosis. Preadmission and in-hospital anticoagulant therapies were positively associated with survival.

Emergency medicine updates: Anaphylaxis.

Anaphylaxis is a potentially deadly condition that requires emergent therapy. While frequently treated in the emergency department (ED), recent evidence updates may improve the diagnosis and management of this condition. This paper evaluates key evidence-based updates concerning the diagnosis and management of anaphylaxis for the emergency clinician. The presentation of anaphylaxis can vary. Current diagnostic criteria can be helpful when evaluating patients for anaphylaxis, though multiple criteria exist. While the most common causes of anaphylaxis include medications, insect venom, and foods, recent literature has identified an IgE antibody response to mammalian galactose alpha-1,3-galactose, known as alpha-gal anaphylaxis. Epinephrine is the first-line therapy and is given in doses of 0.01 mg/kg (up to 0.5 mg in adults) intramuscularly (IM) in the anterolateral thigh. Intravenous (IV) epinephrine administration is recommended in patients refractory to IM epinephrine and IV fluids, or those with cardiovascular collapse. Antihistamines and glucocorticoids should not delay administration of epinephrine and do not demonstrate a significant reduction in risk of biphasic reactions. Biphasic reactions may affect 1-7% of patients with anaphylaxis. Risk factors for biphasic reaction include severe initial presentation and repeated doses of epinephrine. Disposition of patients with anaphylaxis requires consideration of several factors. Emergency clinicians must be aware of current updates in the evaluation and management of this disease.

Endothelial Nitric Oxide Synthase (Glu298Asp) Polymorphism is Associated Significantly with Ischemic Stroke Presenting with Seizures and Altered Sensorium.

Endothelial nitric oxide synthase (eNOS) is an enzymatic marker whose genetic polymorphism might predispose to acute ischemic stroke (AIS) via vascular endothelial dysfunction. It has a potential role in atherosclerosis, making it a plausible risk factor for stroke. Prior studies have failed to prove a conclusive relationship between eNOS polymorphism and AIS. The aim of this study is to find an association between the presence of eNOS polymorphism (Glu298Asp) and the risk of developing AIS. We recruited 307 subjects including 153 AIS cases and 154 healthy controls. The eNOS (Glu298Asp) polymorphism was identified in EDTA blood by PCR amplification of the target region followed by restriction enzyme digestion, and genotyping on Agarose gel. GG, GT and TT genotypes were obtained. Statistical analysis was done using SPSS software version 20. A significant association was found between the presence of TT genotype and the risk of AIS (Odd's ratio (OR): 2.43, P-value = 0.038). There was no significant association between the TT genotype and the traditional stroke risk factors. However, the TT genotype was significantly associated with the presence of altered consciousness (OR: 5.27, 95% CI: 1.59-17.04, P-value = 0.003) and with the occurrence of seizures at presentation (OR: 7.98, 95% CI: 1.99-32.09, P-value = 0.007). There is a significant association between the presence of eNOSpolymorphism (Glu298Asp) and the risk of AIS, and the TT genotype may predispose to a more severe initial presentation of ischemic stroke.

Severe SARS-CoV-2 pneumonia: Clinical, functional and imaging outcomes at 4 months

IntroductionGiven the pathophysiology of coronavirus disease 19 (COVID-19), persistent pulmonary abnormalities are likely. MethodsWe conducted a prospective cohort study in severe COVID-19 patients who had oxygen saturation<94% and were primarily admitted to hospital. We aimed to describe persistent gas exchange abnormalities at 4 months, defined as decreased diffusing capacity of the lungs for carbon monoxide (DLco) and/or desaturation on the 6-minute walk test (6MWT), along with associated mechanisms and risk factors. ResultsOf the 72 patients included, 76.1% required admission to an intensive care unit (ICU), while 68.5% required invasive mechanical ventilation (MV). A total of 39.1% developed venous thromboembolism (VTE). After 4 months, 61.4% were still symptomatic. Functionally, 39.1% had abnormal carbon monoxide test results and/or desaturation on 6MWT; high-flow oxygen, MV, and VTE during the acute phase were significantly associated. Restrictive lung disease was observed in 23.6% of cases, obstructive lung disease in 16.7%, and respiratory muscle dysfunction in 18.1%. A severe initial presentation with admission to ICU (P=0.0181), and VTE occurrence during the acute phase (P=0.0089) were associated with these abnormalities. 41% had interstitial lung disease in computed tomography (CT) of the chest. Four patients (5.5%) displayed residual defects on lung scintigraphy, only one of whom had developed VTE during the acute phase (5.5%). The main functional respiratory abnormality (31.9%) was reduced capillary volume (Vc<70%). ConclusionAmong patients with severe COVID-19 pneumonia who were admitted to hospital, 61% were still symptomatic, 39% of patients had persistent functional abnormalities and 41% radiological abnormalities after 4 months. Embolic sequelae were rare but the main functional respiratory abnormality was reduced capillary volume. A respiratory check-up after severe COVID-19 pneumonia may be relevant to improve future management of these patients.

#82: Osteomyelitis with Panton-Valentine Leukocidin Producing Staphylococcus aureus Strains, Experience in a Tertiary Pediatric Hospital in Mexico City

Abstract Background S. aureus is the most common cause of osteomyelitis in children. Panton-Valentine leucocidin (PVL) is an exotoxin produced by certain S. aureus strains, which can be detected in both methicillin-sensitive and -resistant strains of staphylococci. Pediatric osteomyelitis by PVL producing S. aureus constitute a rare, but highly critical event. They are characterized by a rapid course of marked inflammation, worsening under conservative therapy, and a high rate of recurrence. No information is available on osteomyelitis and Panton-Valentine leukocidin producing S. aureus in Mexico. Objective The aim of this study was to determine the molecular characterization of S. aureus strains isolated in pediatric patients with osteomyelitis and their clinical features in a tertiary hospital in Mexico City. Methods We conducted a prospective study of children admitted for osteomyelitis, between December 2018 and November 2019, at Instituto Nacional de Pediatría. We obtained an informed consent in children under 12 years of age and an informed assent in children over 12. The confirmation of the S. aureus isolates was performed by amplification and analysis of 16S rRNA and nuc genes. The mecA and pvl genes were detected by PCR, the clinical features were obtained at the admission. Results Fifty patients were included and 26 cases of osteomyelitis were diagnosed, 13 were due to staphylococcus aureus genus and 6 due to S. aureus; all of them were methicillin susceptible and two were PVL producers. Both patients had a severe initial presentation, with extensive local abscesses, and one required three surgical procedures and developed septic pulmonary embolism. The two patients received double antimicrobial treatment and required a long therapy interval. Conclusions Osteomyelitis with Panton-Valentine Leukocidin producing S. aureus seems to be more severe. In patients with severe osteomyelitis, it is essential to detect the PVL toxin because they require early surgical intervention and prolonged intravenous therapy. Our findings suggest that the severity of the osteomyelitis is linked with PVL production more than with methicillin resistance due to that all our isolates were methicillin susceptible.

Risk Factors and Outcomes of Hospitalized Patients With Severe Coronavirus Disease 2019 (COVID-19) and Secondary Bloodstream Infections: A Multicenter Case-Control Study.

BackgroundCoronavirus disease 2019 (COVID-19) has become a global pandemic. Clinical characteristics regarding secondary infections in patients with COVID-19 have been reported but detailed microbiology, risk factors and outcomes of secondary bloodstream infections (sBSI) in patients with severe COVID-19 have not been well described.MethodsWe performed a multicenter, case-control study including all hospitalized patients diagnosed with severe COVID-19 and blood cultures drawn from March 1, 2020 to May 7, 2020 at three academic medical centers in New Jersey, USA. Data collection included demographics, clinical and microbiologic variables, and patient outcomes. Risk factors and outcomes were compared between cases (sBSI) and controls (no sBSI).ResultsA total of 375 hospitalized patients were included. There were 128 sBSIs during the hospitalization. For the first set of positive blood cultures, 117 (91.4%) were bacterial and 7 (5.5%) were fungal. Those with sBSI were more likely to have altered mental status, lower mean percent oxygen saturation on room air, have septic shock and be admitted to the intensive care unit compared to the controls. In-hospital mortality was higher in those with a sBSI versus controls (53.1% vs 32.8%, p=0.0001).ConclusionsWe observed hospitalized adult patients with severe COVID-19 and sBSI had a more severe initial presentation, prolonged hospital course, and worse clinical outcomes. To maintain antimicrobial stewardship principles, further prospective studies are necessary to better characterize risk factors and prediction modeling to better understand when to suspect and empirically treat for sBSI in severe COVID-19.

Bell’s palsy workup: Does audiometry add value?

ObjectiveTo investigate if routine audiometry in Bell’s palsy patients has prognostic value. MethodsRetrospective case review was conducted on all Bell’s palsy patients (n=191) seen at the tertiary otolaryngology specialist outpatient clinic from 2015 to 2017. Correlation of ipsilesional audiometric thresholds with patients’ time-to-recovery and initial clinical severity (measured by House-Brackmann (HB) scoring) were used for the prognostic outcome measure. Audiometry results were analyzed using three contiguous frequency pure-tone average (1kHz, 2kHz, 4kHz). Statistical analysis was done via Stata (v13.1), significance tests were 2-sided at 5% significance level. ResultsThere was no significant difference between audiometric thresholds between the ipsilesional ear and the contralateral ear (p=0.87). Time-to-recovery was significantly longer for patients with severe initial presentation as compared to mild and moderate severity (p<0.01). There was no correlation found between the audiometry results and HB score at presentation (p=0.39). There was no correlation found between ipsilesional audiometric thresholds and time-to-recovery (p=0.58). ConclusionOur study suggests that routine audiometry has limited prognostic value in Bell’s palsy patients.

Clinical characteristics and long-term health in celiac disease patients diagnosed in early childhood: Large cohort study

BackgroundEarly detection of celiac disease could theoretically prevent most of the disease-associated complications, but long-term effects of this approach are unclear. AimsTo investigate features at diagnosis and adulthood health in celiac disease patients diagnosed in early childhood in 1965–2014. MethodsMedical data on 978 pediatric patients were collected and study questionnaires sent to 559 adult patients who were diagnosed in childhood. Results were compared between patients diagnosed in early (≤3.0 years) and later (3.1-17.9 years) childhood. ResultsEarly diagnosed patients (n=131) had more often total villous atrophy (37% vs 25%, p=0.001), gastrointestinal presentation (61% vs 47%, p<0.001), growth disturbances (70% vs 32%, p=0.001) and severe symptoms (30% vs 9%, p<0.001) and were less often screen-detected (10% vs 27%, p<0.001) at diagnosis than those diagnosed later (n=847).Among 239 adult responders, early diagnosed patients (n=36) had fewer comorbidities (33% vs 53%, p=0.034) but considered their health less often good/excellent (69% vs 84%, p=0.029). The groups were comparable in current age, dietary adherence, symptoms and health-related quality of life. ConclusionDespite more severe initial presentation, the long-term health in early diagnosed patients was mostly comparable or even better to those diagnosed later in childhood. Poorer self-perceived health suggests a need for support during the transition to adulthood care.
