Difficult intubation provokes bacteremia
Abstract Purpose: To evaluate the prevalence of bacteremia after mask ventilation, laryngoscopy, and endotracheal intubation before induction of general anesthesia and to discover any correlation between traumatic manipulations and bacteremia. The specific bacteria responsible, knowledge of which may guide the prophylactic use of antibiotics, also were investigated. Methods: Fifty patients were enrolled. Three 10-mL blood samples were collected from a peripheral vein 10 min before induction of anesthesia, 10 min after mask ventilation, and 10 min after intubation. All samples were placed in aerobic and anaerobic bottles for culture and bacterial identification. Results: Cultures received 10 min after intubation were positive in 12% of patients. The following strains were isolated: Escherichia coli in two cases, Staphylococcus aureus in three cases, and Peptostreptococcus anaerobius in one case. A strong positive correlation was found between difficult intubation and bacteremia. No correlation between bacteremia and easy intubation or between bacteremia and face mask ventilation was identified. Conclusion: Traumatic manipulations during difficult laryngoscopy and endotracheal intubation could cause bacteremia. This finding may justify and guide prophylactic use of antibiotics. 52
Efficacy and safety of abrocitinib in patients with moderateâtoâsevere atopic dermatitis and comorbid allergies
Background: Abrocitinib efficacy by comorbidity status in patients with moderateâtoâsevere atopic dermatitis (AD) has not been previously assessed. This post hoc analysis evaluated the efficacy and safety of abrocitinib in patients with AD and allergic comorbidities.
Methods: Data were pooled from patients who received abrocitinib 200âmg, 100âmg, or placebo in phase 2b (NCT02780167) and phase 3 (NCT03349060, NCT03575871) monotherapy trials. Patients with and without allergic comorbidities (allergic asthma, rhinitis, conjunctivitis, or food allergy) were evaluated for Investigator's Global Assessment (IGA) response (clear [0] or almost clear [1]), â„75% improvement in the Eczema Area and Severity Index (EASIâ75), â„4âpoint improvement in Peak Pruritus Numerical Rating Scale (PPâNRS4), and Dermatology Life Quality Index (DLQI) response (<2 with baseline score â„2). Other outcomes were PatientâOriented Eczema Measure (POEM), SCORing Atopic Dermatitis (SCORAD), Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD), and treatmentâemergent adverse events (TEAEs).
Results: Of 942 patients, 498 (53%) reported at least one allergic comorbidity (asthma only, 33%; conjunctivitis only or rhinitis only or both, 17%; food allergies only, 15%; >1 allergic comorbidity, 34%). Regardless of comorbidity status, from Week 2 to Week 12, higher percentages of patients treated with either abrocitinib dose achieved IGA 0/1, EASIâ75, PPâNRS4, or DLQI 0/1 versus placeboâtreated patients. Changes from baseline in POEM, SCORAD, and PSAAD were greater with abrocitinib than with placebo in patients with and without allergic comorbidities. Most TEAEs were mild or moderate.
Conclusions: Efficacy and safety data support abrocitinib use to manage AD in patients with or without allergic comorbidities
The seed germination properties of two hyperaccumulator plant species with the potential for Ni agromining
The aim of this study is to investigate the effect of different nickel concentrations and light in combination with storage conditions and storage time on the
seed germination ability of two serpentine-endemic nickel hyperaccumulating
species (Bornmuellera emarginata and B. tymphaea). The seeds of both species
were collected from natural populations in the Pindus Mountain range, Greece
in early July and stored in a refrigerator (4°C) and in laboratory conditions
(22°C). The seeds were exposed to a range of nickel concentrations typical of
non-ultramafic â ultramafic gradient in two light environments (12 h photoperiod and continuous darkness). The nickel concentration only had a significant
effect on B. emarginata, decreasing its seed germination rate with increasing
Ni concentrations. The storage temperature significantly affected the germination percentage of both species and it was higher at 4°C compared to 22°C. A
higher germination rate (> 60%) was observed for 5â8-month-old seeds, but
both species generally showed significantly higher germination rates in the tests
conducted seven months after seed ripening in the field. A higher germination
rate was observed in a 12-hour photoperiod than in continuous darkness only
for B. tymphaea. This study provides guidelines on the germination capacity of
two obligate nickel hyperaccumulators with a potential for use in agromining
systems
Blurred vision due to choroidal metastasis as the first manifestation of lung cancer: A case report
<p>Abstract</p> <p>Background</p> <p>Reduction in visual acuity combined with blurred vision is rarely the first sign of lung cancer and very few cases have been announced globally.</p> <p>Case presentation</p> <p>A case of a 46-year-old man who admitted with blurred vision is presented. His medical history, apart from a mild gastritis under treatment was negative. Ocular examination revealed a decrease in visual acuity due to a choroidal tumor. Further image body scans demonstrated a right lung lesion with dissemination to other organs. Diagnosis of a non-small cell lung cancer established after a VATS biopsy carried out.</p> <p>Conclusion</p> <p>Blurred vision due to choroidal metastasis as the primary symptom of lung cancer is very uncommon. A great index of suspicion is essential when a choroidal lesion appears.</p
Clinical effectiveness of thrombus aspiration during percutaneous coronary intervention for stent thrombosis in a contemporary setting
Objective-
The impact of adjunctive manual thrombus aspiration (TA) in patients with stent thrombosis (ST) treated with percutaneous intervention has not been evaluated in the current era of potent P2Y12 agents and new-generation drug-eluting stents. We sought to assess the effect of TA using data from a large contemporary registry.
Methods-
The study population was derived from the Essex ST Investigation Registry (ESTHIR), which contains all consecutive cases of angiographically determined definite ST undergoing interventional treatment in a tertiary cardiac centre between November 2015 and June 2018. Propensity score matching was performed to match patients who underwent TA (TA group) to those who did not (n-TA group). The study endpoints were final TIMI flow and survival free of cardiovascular death (CD) or target lesion revascularisation (TLR).
Results-
A total of 128 ST patients were included in the present analysis. The mean age was 65 ± 11 years, and 84% were male. About 90% of the patients presented with STEMI, and 85% had very late ST. Seventy-two patients (56%) underwent TA. After propensity score matching, 30 patients were included in each study group. A higher rate of final TIMI III flow was observed in the TA group (TA vs n-TA group, 100% vs 83%), but this difference did not reach statistical significance (p = 0.052). At 1000 days of follow-up, survival free of CD or TLR was not different between the two groups (p = 0.8).
Conclusion-
In a propensity-matched population of ST patients undergoing PCI in a contemporary setting, TA was not associated with improved final TIMI flow or long-term cardiovascular outcomes
In chronic spontaneous urticaria soluble FcΔRI is elevated and linked to atopy and chronic inducible urticaria
A comparative analysis of colourâemotion associations in 16â88âyearâold adults from 31 countries
As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact their mood and overall well-being. However, there is a lack of empirical evidence to provide informed guidance on colour choices, irrespective of age group. To work towards informed choices, we investigated whether the associations between colours and emotions observed in younger individuals also apply to older adults. We recruited 7,393 participants, aged between 16 and 88 years and coming from 31 countries. Each participant associated 12 colour terms with 20 emotion concepts and rated the intensity of each associated emotion. Different age groups exhibited highly similar patterns of colour-emotion associations (average similarity coefficient of 0.97), with subtle yet meaningful age-related differences. Adolescents associated the greatest number but the least positively biased emotions with colours. Older participants associated a smaller number but more intense and more positive emotions with all colour terms, displaying a positivity effect. Age also predicted arousal and power biases, varying by colour. Findings suggest parallels in colour-emotion associations between younger and older adults, with subtle but significant age-related variations. Future studies should next assess whether colour-emotion associations reflect what people actually feel when exposed to colour
International consensus guidelines for the diagnosis and management of food proteinâinduced enterocolitis syndrome: Executive summaryâWorkgroup Report of the Adverse Reactions to Foods Committee, American Academy of Allergy, Asthma & Immunology
Food protein-induced enterocolitis (FPIES) is a non-IgE cell- mediated food allergy that can be severe and lead to shock. Despite the potential seriousness of reactions, awareness of FPIES is low; high-quality studies providing insight into the pathophysiology, diagnosis, and management are lacking; and clinical outcomes are poorly established. This consensus document is the result of work done by an international workgroup convened through the Adverse Reactions to Foods Committee of the American Academy of Allergy, Asthma & Immunology and the International FPIES Association advocacy group. These are the first international evidence-based guidelines to improve the diagnosis and management of patients with FPIES. Research on prevalence, pathophysiology, diagnostic markers, and future treatments is necessary to improve the care of patients with FPIES. These guidelines will be updated periodically as more evidence becomes available
