Generalized Spike-Waves, Multiple Loci, and Clinical Course in Children with EEG Features of Benign Epilepsy of Childhood with Centrotemporal Spikes

In 41 patients with EEG features of benign epilepsy of childhood with centrotemporal spikes (BECCT), we noted associated generalized spike-wave discharges (GSWD) in 14.6% and multiple independent sharp wave foci in 9.8%. The presence or absence of these EEG features was not predictive of the clinical course. The high incidence of GSWD in children with BECCT suggests a possible relation in the expression of these two EEG traits.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66418/1/j.1528-1157.1992.tb01764.x.pd

EEG abnormalities aid diagnosis of Rett syndrome

Nine girls with Rett syndrome had 22 electroencephalographic studies performed over 5 years. Nineteen waking tracings demonstrated moderate background slowing. Focal epileptiform activity was observed in 13 studies, 10 of which had bilateral independent foci. Spikes were invariably maximal in central regions, diphasic or triphasic, and of very short duration. In 3 patients, epileptiform activity preceded clinical seizures by up to 2 years. Two children had spontaneous hyperpnea preceding apnea during wakefulness with further background slowing. Video monitoring of 2 children revealed that episodic behavioral changes were not seizures. Ten of 12 sleep recordings had abnormal background activity with absent or rudimentary spindles. Normal activity occurred only in girls younger than years of age. Epileptiform activity was markedly increased during sleep in 8 tracings in which both wakefulness and sleep were obtained. It was characterized by bilaterally independent and bisynchronous spike-and-wave activity, maximal in parasagittal areas. One patient had bursts of high-voltage slow-wave activity followed by attenuation. No apneic episodes were recorded during sleep. In Rett syndrome, electroencephalographic abnormalities include background slowing, centrally located short-duration spikes, and increased epileptiform activity during sleep. This activity commonly preceded clinical seizures in patients studied at initial presentation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27084/1/0000075.pd

Epileptiform abnormalities during sleep in Rett syndrome

We recorded all-night electroencephalograms (EEGs)/polysomnograms on 2 consecutive nights from 4 children (ages 4-11 years) with Rett syndrome. The first 10 sec of each 60 sec epoch were analyzed with counts of left and right hemisphere spikes and correlated with sleep stage. Spike counts were lowest during wakefulness. Spikes were most frequent over parasagittal regions during all sleep stages and varied from 0.28+/-0.03 to 40.4+/-0.7 (mean+/-S.E.M.) spikes/hemisphere/min. Spike counts were 51-109% higher during NREM sleep than during REM sleep. In 3 of 4 subjects, spikes were most frequent during light NREM sleep. Spikes increased in frequency during the second half of the night. We conclude that in Rett syndrome, epileptiform activity is maximally expressed in stage 1-2 NREM sleep and during the early morning hours. Sleep EEG features may be useful in the diagnosis of Rett syndrome.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28605/1/0000414.pd

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
