Large Outbreak

Background. In 2011, a multistate outbreak of listeriosis linked to contaminated cantaloupes raised concerns that many pregnant women might have been exposed toListeria monocytogenes. Listeriosis during pregnancy can cause fetal death, premature delivery, and neonatal sepsis and meningitis. Little information is available to guide healthcare providers who care for asymptomatic pregnant women with suspectedL. monocytogenesexposure.Methods. We tracked pregnancy-associated listeriosis cases using reportable diseases surveillance and enhanced surveillance for fetal death using vital records and inpatient fetal deaths data in Colorado. We surveyed 1,060 pregnant women about symptoms and exposures. We developed three methods to estimate how many pregnant women in Colorado ate the implicated cantaloupes, and we calculated attack rates.Results. One laboratory-confirmed case of listeriosis was associated with pregnancy. The fetal death rate did not increase significantly compared to preoutbreak periods. Approximately 6,500–12,000 pregnant women in Colorado might have eaten the contaminated cantaloupes, an attack rate of ~1 per 10,000 exposed pregnant women.Conclusions. Despite many exposures, the risk of pregnancy-associated listeriosis was low. Our methods for estimating attack rates may help during future outbreaks and product recalls. Our findings offer relevant considerations for management of asymptomatic pregnant women with possibleL. monocytogenesexposure.

AbstractBackgroundEstimating the actual number of COVID-19 infections is crucial for steering through the COVID-19 pandemic crisis. It is, however, notoriously difficult, as many cases have no or only mild symptoms. Surveillance data for in-household secondary infections offers unbiased samples for COVID-19 prevalence estimation.MethodsWe analyse 16 115 Polish surveillance records to obtain key figures of the COVID-19 pandemic. We propose conservative upper and lower bound estimators for the number of SARS-CoV-2 infections. Further, we estimate age-dependent bounds on the severe case rate, death rate, and the in-household attack rate.ResultsBy maximum likelihood estimates, the total number of COVID-19 cases in Poland as of July 22nd, 2020, is at most around 13 times larger and at least 1.6 times larger than the recorded number. The lower bound on the severeness rate ranges between 0.2% for the 0–39 year-old to 5.7% for older than 80, while the upper bound is between 2.6% and 34.1%. The lower bound on the death rate is between 0.04% for the age group 40–59 to 1.34% for the oldest. Overall, the severeness and death rates grow exponentially with age. The in-household attack ratio is 8.18% for the youngest group and 16.88% for the oldest.ConclusionsThe proposed approach derives highly relevant figures on the COVID-19 pandemic from routine surveillance data, under assumption that household members of detected infected are tested and all severe cases are diagnosed.MOCOSThe MOCOS (MOdelling COrona Spread) international research group is an interdisciplinary scientific consortium.

Background: Intracranial atherosclerotic stenosis is a major cause of stroke and yet there are currently no proven effective treatments for it. The SAMMPRIS trial, comparing aggressive medical management alone with aggressive medical management combined with intracranial angioplasty and stenting, was prematurely halted when an unexpectedly high rate of periprocedural events was found in the endovascular arm. The goal of our study is to report the immediate and long-term outcomes of patients with ≥ 70 % symptomatic intracranial atherosclerotic stenosis treated with balloon angioplasty and stent placement in a single centre. Patients and methods: This is a retrospective review of 37 consecutive patients with 42 procedures of ballon angioplasty and stenting for intracranial atherosclerotic stenosis (≥ 70 % stenosis) treated between 1999 and 2012. Technical success (residual stenosis ≤ 50 %), periprocedural success (no vascular complications within 72 hours), and long-term outcomes are reported. Results: Technical and periprocedural success was achieved in 90.5 % of patients. The within 72 hours periprocedural stroke/death rate was 7.1 % (4.8 % intracranial haemorrhage), and the 30-day stroke/death rate was 9.5 %. Thirty patients (81 %) had clinical follow-up at ≥ 6 months. During follow-up, 5 patients developed 6 ischemic events; 5 of them (17 %) were ipsilateral. The restenosis rate was 27 %, and the retreatment rate was 12 %. Conclusions: Our outcomes of the balloon angioplasty/stent placement for intracranial atherosclerotic stenosis are better than those in the SAMMPRIS study and compare favourably with those in large registries and observational studies.
