01), significantly lower E wave velocities (P < 0.01) and left ventricle mass (P < 0.01), and lower values of relative wall thickness (P < 0.01). Compared with subjects in their 70s and 80s in the studies by Daimon and Okura, the E and A wave velocities were higher.

We established the normal range of TTE parameters in elderly patients who had LV ejection fraction > 55% without cardiac, renal, or aortic disease. Sex differences were present as well as a tendency towards age-related changes in LV geometry and diastolic function. ActinomycinD Most of the patients aged  over 90years had LV hypertrophy and potential diastolic dysfunction.

Nonintubated chest trauma patients with fractured ribs admitted to the intensive care unit (ICU) are at risk for complications and may require invasive ventilation at some point. Effective pain control is essential. We assessed whether epidural analgesia (EA) in patients with fractured ribs who were not intubated at ICU admission decreased the need for invasive mechanical ventilation (IMV). We also looked for risk factors for IMV.

This retrospective, observational, multicenter study conducted in 40 ICUs in France included consecutive patients with three or more fractured ribs who were not intubated at admission between July 2013 and July 2015.

Of the 974 study patients, 788 were included in the analysis of intubation predictors. EA was used in 130 (16.5%) patients, and 65 (8.2%) patients required IMV. Factors independently associated with IMV were chronic respiratory disease (P = 0.008), worse SAPS II (P < 0.0001), flail chest (P = 0.02), worse Injury Severity Score (P = 0.0003), higher respiratory rate at admission (P = 0.02), alcohol withdrawal syndrome (P < 0.001), and noninvasive ventilation (P = 0.04). EA was not associated with decreases in IMV requirements, median numerical rating scale pain score, or intravenous morphine requirements from day 1 to day 7.

EA was not associated with a lower risk of IMV in chest trauma patients with at least 3 fractured ribs, moderate pain, and no intubation on admission. Further studies are needed to clarify the optimal pain control strategy in chest trauma patients admitted to the ICU, notably those with severe pain or high opioid requirements.

Known atrial fibrillation (AF) rate and appropriate prescription of oral anticoagulants (OACs) in acute ischemic stroke (AIS) patients with AF in China are not as well known as in Western countries.

Known AF and unknown AF, rate and adequacy of OACs use of AIS patients with AF attending five hospitals from April 2018 to August 2019 in the northwest region of China were investigated.

A total of 344 patients were enrolled. Of these, 237 (AF-known group; 237/344, 68.9%) and 107 patients (AF-unknown group; 107/344, 31.1%) were diagnosed with AF before and after AIS during this hospitalization, respectively. In the AF-known group with echocardiography results (178 patients, including 103 female and 75 male patients), 154 of overall, 88 of female and 66 of male patients, respectively, were indicated to be taking OACs. However, the actual OACs proportion was much lower [overall (30.5%, 47/154); female (31.8%, 28/88) and male (28.8%, 19/66) patients] than indicated. Only one female patient met the guideline-based criteria for OACs. As for patients diagnosed with massive cerebral infraction (MCI; 43.0%, 148/344), the known AF rate was 65.5% (97/148). Among the MCI patients in the AF-known group with echocardiography results (61 patients), 50 patients had an OACs indication. However, only 22.0% (11/50) of these patients took OACs, and none met the guideline-based criteria for OACs.

This study revealed a low known AF rate, low OACs use rate and low rate of meeting the guideline-based criteria for OACs in AIS patients with AF in the northwest region of China. These findings indicated the importance of AF as a public health problem in China.

The zoonotic HEV genotype 3, which is highly prevalent in Europe, is mainly transmitted by consumption of raw meat and raw meat products produced from infected pigs or wild boars. High salt concentrations represent an important measure to preserve meat products and to inactivate foodborne pathogens. Here, an HEV preparation in phosphate-buffered saline (PBS) was subjected to different salt concentrations and the remaining infectivity was measured in a cell culture assay. Treatments with up to 20% sodium chloride for 24 h at 23 °C, with and without addition of 0.015% sodium nitrite or 0.03% sodium nitrate, did not lead to virus inactivation as compared to PBS only. Conditions usually applied for short-term and long-term fermented raw sausages were simulated by incubation at 22 °C for up to 6 days and at 16 °C for up to 8 weeks, respectively. Only 2% sodium chloride with 0.015% sodium nitrite showed a weak ( less then  1 log10), but significant, infectivity reduction after 2 and 4 days as compared to PBS only. Addition of 2% sodium chloride and 0.03% sodium nitrate showed a slight, but not significant, decrease in infectivity after 2 and 8 weeks as compared to PBS only. In conclusion, HEV is highly stable at high salt concentrations and at salt conditions usually applied to preserve raw meat products.
