Toxic Shock-like Syndrome Associated with Necrotizing Streptococcus Pyogenes Infection

Two patients with toxic shock-like syndrome are presented. Both patients had necrotizing cellulitis due to Streptococcus pyogenes, and both patients required extensive surgical debridement. The association of Streptococcus pyogenes infection and toxic shock-like syndrome is discussed

Impact of stroke‐associated pneumonia on mortality, length of hospitalization, and functional outcome

Objectives: Stroke‐associated pneumonia (SAP) is common and associated with adverse outcomes. Data on its impact beyond 1 year are scarce. Materials and methods: This observational study was conducted in a cohort of stroke patients admitted consecutively to a tertiary referral center in the east of England, UK (January 2003‐April 2015). Logistic regression models examined inpatient mortality and length of stay (LOS). Cox regression models examined longer‐term mortality at predefined time periods (0‐90 days, 90 days‐1 year, 1‐3 years, and 3‐10 years) for SAP. Effect of SAP on functional outcome at discharge was assessed using logistic regression. Results: A total of 9238 patients (mean age [±SD] 77.61 ± 11.88 years) were included. SAP was diagnosed in 1083 (11.7%) patients. The majority of these cases (n = 658; 60.8%) were aspiration pneumonia. After controlling for age, sex, stroke type, Oxfordshire Community Stroke Project (OCSP) classification, prestroke modified Rankin scale, comorbidities, and acute illness markers, mortality estimates remained significant at 3 time periods: inpatient (OR 5.87, 95%CI [4.97‐6.93]), 0‐90 days (2.17 [1.97‐2.40]), and 91‐365 days (HR 1.31 [1.03‐1.67]). SAP was also associated with higher odds of long LOS (OR 1.93 [1.67‐2.22]) and worse functional outcome (OR 7.17 [5.44‐9.45]). In this cohort, SAP did not increase mortality risk beyond 1 year post‐stroke, but it was associated with reduced mortality beyond 3 years. Conclusions: Stroke‐associated pneumonia is not associated with increased long‐term mortality, but it is linked with increased mortality up to 1 year, prolonged LOS, and poor functional outcome on discharge. Targeted intervention strategies are required to improve outcomes of SAP patients who survive to hospital discharge

A Crucial Role for Antimicrobial Stewardship in the Midst of COVID-19

As the world deals with a pandemic, there remains another global challenge that cannot be ignored. Use of broad-spectrum antibiotics may be justified, as we are trying to treat a novel disease condition, which, in turn, could lead to an increase in antimicrobial resistance. We can decrease morbidity, mortality, and health care costs by controlling antimicrobial resistance, but it requires antimicrobial stewardship. Major components of effective and timely antimicrobial stewardship are diagnostic stewardship, infection prevention and control, and integration of COVID-19-specific flags into electronic health records, all of which may be integrated into current strategies of COVID-19 mitigation and management. Going through the influenza season of 2020, implementation of antimicrobial stewardship education efforts in the United States can help us contend with influenza in addition to COVID-19 and any bacterial coinfections or secondary infections. Additional solutions include the development of vaccines, alternative therapies, such as antibodies, and advanced diagnostics using advances in genomics and computer science

The peripheral blood transcriptome in septic cardiomyopathy: an observational, pilot study.

BACKGROUND:Septic cardiomyopathy (SCM) is common in sepsis and associated with increased morbidity and mortality. Left ventricular global longitudinal strain (LV GLS), measured by speckle tracking echocardiography, allows improved identification of impaired cardiac contractility. The peripheral blood transcriptome may be an important window into SCM pathophysiology. We therefore studied the peripheral blood transcriptome and LV GLS in a prospective cohort of patients with sepsis. RESULTS:In this single-center observational pilot study, we enrolled adult patients (age > 18) with sepsis within 48 h of admission to the ICU. SCM was defined as LV GLS > - 17% based on echocardiograms performed within 72 h of admission. We enrolled 27 patients, 24 of whom had high-quality RNA results; 18 (75%) of 24 had SCM. The group was 50% female and had a median (IQR) age of 59.5 (48.5-67.0) years and admission APACHE II score of 21.0 (16.0-32.3). Forty-six percent had septic shock. After filtering for low-expression and non-coding genes, 15,418 protein coding genes were expressed and 73 had significantly different expression between patients with vs. without SCM. In patients with SCM, 43 genes were upregulated and 30 were downregulated. Pathway analysis identified enrichment in type 1 interferon signaling (adjusted p < 10-5). CONCLUSIONS:In this hypothesis-generating study, SCM was associated with upregulation of genes in the type 1 interferon signaling pathway. Interferons are cytokines that stimulate the innate and adaptive immune response and are implicated in the early proinflammatory and delayed immunosuppression phases of sepsis. While type 1 interferons have not been implicated previously in SCM, interferon therapy (for viral hepatitis and Kaposi sarcoma) has been associated with reversible cardiomyopathy, perhaps suggesting a role for interferon signaling in SCM

Association of left ventricular longitudinal strain with central venous oxygen saturation and serum lactate in patients with early severe sepsis and septic shock

Syftet med denna studie är att synliggöra pedagogers syn på föräldrasamverkan i förskolan. Vi har även intresserat oss på samverkan mellan pedagogerna och föräldrar med annat modersmål än svenska. Vår studie grundar sig på observationer kring bemötande av föräldrar på förskolan. Vi undersökte hur pedagogerna såg på föräldrasamverkan och hur de arbetar kring samverkan med föräldrar, för att kunna få en bredare syn i vår studie om hur samverkan fungerar på de aktuella förskolorna. Som metod använde vi kvalitativ intervju då detta lämpade sig väl för oss för att vi skulle kunna få en bredare syn om hur samverkan fungerar på de aktuella förskolorna. Intervjuer ger mer exakta svar och det underlättar för oss som intervjuar att ställa följdfrågor. Resultatet visar att samverkan med föräldrar har ökat i förskolan och blivit en stor del av verksamheten. Pedagogerna försöker engagera sig mycket i arbetet med föräldrasamverkan och letar efter möjligheter för att skapa en bra kommunikation med föräldrar som har annat modersmål än svenska. Resultaten visar även att pedagogerna menar att oavsett om föräldrarna behärskar det svenska språket eller inte så anstränger de sig för att visa föräldrarna att de är viktiga i verksamheten

The assessment of circulating volume using inferior vena cava collapse index and carotid Doppler velocity time integral in healthy volunteers: a pilot study

International audienceBackground: Assessment of circulating volume and the requirement for fluid replacement are fundamental to resuscitation but remain largely empirical. Passive leg raise (PLR) may determine fluid responders while avoiding potential fluid overload. We hypothesised that inferior vena cava collapse index (IVCCI) and carotid artery blood flow would change predictably in response to PLR, potentially providing a non-invasive tool to assess circulating volume and identifying fluid responsive patients.Methods: We conducted a prospective proof of concept pilot study on fasted healthy volunteers. One operator measured IVC diameter during quiet respiration and sniff, and carotid artery flow. Stroke volume (SV) was also measured using suprasternal Doppler. Our primary endpoint was change in IVCCI after PLR. We also studied changes in IVCCI after “sniff”, and correlation between carotid artery flow and SV.Results: Passive leg raise was associated with significant reduction in the mean inferior vena cava collapsibility index from 0.24 to 0.17 (p < 0.01). Mean stroke volume increased from 56.0 to 69.2 mL (p < 0.01). There was no significant change in common carotid artery blood flow. Changes in physiology consequent upon passive leg raise normalised rapidly.Discussion: Passive leg raise is associated with a decrease of IVCCI and increase in stroke volume. However, the wide range of values observed suggests that factors other than circulating volume predominate in determining the proportion of collapse with respiration.Conclusion: In contrast to other studies, we did not find that carotid blood flow increased with passive leg raise. Rapid normalisation of post-PLR physiology may account for this
