Abstract
Abstract
Background
In order to differentiate perioperative myocardial infarction/injury (PMI) after non-cardiac surgery from preexisting cardiomyocyte injury from chronic disorders, recent studies have shown the importance of using an acute absolute increase as a criterion for PMI. For high-sensitivity troponin T (hs-cTnT), PMI defined as an absolute increase of 14ng/L (the 99th percentile) has been shown to be strongly associated with 30-day mortality. Until now, no data on hs-cTnI are available. This is a major unmet clinical need, as relevant differences between hs-cTnT and hs-cTnI have recently been identified and, as worldwide hs-cTnI is more commonly used as compared to hs-cTnT. We hypothesized that applying the same criterion to hs-cTnI, would reveal a similar association with outcomes.
Purpose
To evaluate the incidence and outcome of PMI diagnosed by hs-cTnI after non-cardiac surgery.
Methods
We included prospectively consecutive high cardiovascular risk patients undergoing non-cardiac surgery. Hs-cTnI concentrations were measured before surgery and, daily after surgery, for three days. PMI was defined as an absolute rise of ≥26ng/L (the 99th percentile of the assay studied) from baseline values. The primary outcome was major adverse cardiovascular events (MACE), a composite of cardiovascular death, myocardial infarction, acute heart failure and arrhythmias, and the secondary outcome was all-cause mortality, within 30 days and one year.
Results
We included 2,018 patients submitted to 2,551 surgeries. Patients had median age of 73 years (IQR 68–79) and 56% were male. After surgery, 231 patients (9%, 95% CI 8–10%) fulfilled PMI diagnostic criterion. Patients with PMI had higher rates of MACE than patients without PMI, at 30 days (13% vs. 2%; P<0.001) and, at one-year follow-up (25% vs. 8%; P<0.001). All-cause mortality was also higher in PMI patients within 30 days and one year (9% vs. 1.5% and, 22% vs. 8%, respectively; P<0.001). In multivariate cox regression analysis, PMI showed a hazard ratio (HR) of 4.7 (95% CI, 2.9–7.6; P<0.001) within 30 days, and a HR of 2.7 (95% CI, 2.0–3.7; P<0.001) within one year for the occurrence of MACE. For total mortality, PMI showed a HR of 3.8 (95% CI, 2.1–6.8; P<0.001) within 30 days and a HR of 2.0 (95% CI, 1.4–2.7; P<0.001) after one year.
Conclusion
PMI is frequent and associated with high rates of MACE and mortality in short- and long-term follow-up after non-cardiac surgery, regardless of the high-sensitivity troponin assay used for diagnosis.

Abstract
Abstract
Background
Perioperative myocardial injuries (PMI) are a common complication following non-cardiac surgery associated with significantly increased postoperative mortality. Due to its mostly asymptomatic presentation it is currently often missed in clinical routine. With the advent of routine screening PMI will be an increasingly recognised. Therefore, a more detailed understanding of the different etiologies causing PMI is needed to guide management.
Methods
We included consecutive high-risk patients (defined as known cardiovascular disease or aged ≥65 years) undergoing major non-cardiac surgery at two hospitals into this prospective multicenter observational study. All patients received a systematic screening using cardiac troponin (cTn) in clinical routine for detection of PMI, defined as an absolute cTn-rise from baseline values within 3 days of surgery. Patients were contacted to assess occurrence of major adverse events (MACE) including all-cause death at 30-days. First, we identified preoperative existing comorbidities as well as perioperative factors associated with PMI by multivariable regression analysis. Second, PMI were centrally adjudicated to identify predefined subtypes (“type I myocardial infarction (T1MI)”, “acute heart failure” (AHF), “tachyarrhythmia”, “extra-cardiac” triggers, “unknown”) by two independent reviewers using all clinical information available, and subtypes tested for association with 30-day (MACE).
Results
From 2014 to 2016 we enrolled 4250 patients undergoing 5375 surgeries. PMI occurred after 785 (14,5%) surgeries. Occurrence of PMI was more frequent with older age and cardiovascular comorbidities, especially insulin-dependent diabetes mellitus and chronic kidney disease. Perioperatively multiple known type II triggers (hypotension, bleeding, hypoxemia, tachycardia, length of surgery) were associated with PMI. Only 5,0% of PMI were adjudicated as “T1MI”, 4,3% as “AHF”, 4,3% as “tachyarrhythmia”, 12,0% “extra-cardiac” and the majority of 74,4% as “unknown”. The subtypes were associated increased MACE-rates (24% for T1MI, 40% for “AHF”, 22% for “tachyarrhythmia”, 24% for “extra-cardiac”, 7,1% for “unknown”) compared to non-PMI patients (1,8%, p<0,001 see Figure).
MACE within 30 days following surgery
Conclusion
PMI occurs more likely in patients with preoperative existing comorbidities, PMI are associated with type II triggers in the intra- as well as postoperative period. We identified subtypes allowing a risk-stratification to identify high-risk types and guide clinical management.

Abstract
Viroids of fruit trees are plant pathogens distributed worldwide and can cause severe losses and economic damage to crops. A survey of fruit trees was carried out in 17 orchards in the northern and Sahel regions of Tunisia. Samples were collected in field trees of peach (Prunus persica L), pear (Pyrus communis L), and almond (Prunus dulcis Mill.) that showed symptoms potentially caused by viroids (leaf mosaic in peach, blister canker in pear, and necrotic leaves in almond). The investigation was conducted during May, September, and December 2003 to screen for the presence of Pear blister canker viroid (PBCVd) on pear, Peach latent mosaic viroid (PLMVd) on peach, and Hop stunt viroid (HSVd) on the three plant species in naturally infected field trees. The detection method was based on one-tube reverse transcription-polymerase chain reaction (RT-PCR) assays using a Titan kit (Roche Diagnostics, Penzberg, Germany). DNA amplification was obtained by using previously reported primer pairs for PLMVd and HSVd (1,4). For PBCVd, forward primer 5' GTCTGAAGCCTGGGCGCTGG 3' and reverse primer 5' CCTTCGT CGACGACGAGCCGAG 3' were designed using an available sequence (3). Positive controls included isolate D168 of PLMVd (obtained from Dr. B. Pradier, Station de Quarantaine des Ligneux, Lempdes, France) and propagated in GF 305 rootstock and HSVd (provided by Dr. R. Flores, Instituto de Biologia Molecular y cellular de Plantas, Valencia, Spain) propagated in cucumber. The method described by Grasseau et al. (2), with some modifications, was used to prepare the samples for RT-PCR. RT-PCR analysis of nucleic acid preparations from leaves and bark of peach, pear, and almond showed that PLMVd occurred in the northern and Sahel regions of Tunisia. Of 37 peach trees tested, 12 were found infected with PLMVd. Two pear trees among 73 tested were infected with PBCVd. HSVd was detected in 2 of 11 almond, 1 of 37 peach, and 7 of 72 pear trees tested. One pear tree infected with HSVd was also infected with PBCVd. Symptoms observed in fruit trees were not consistently associated with the presence of viroids. Nucleotide sequence analyses of cloned amplification products obtained using the PBCVd, PLMVd, and HSVd primers confirmed a size of 315, 330, and 300 nt, respectively, and revealed a sequence similar to sequence variants from other isolates previously characterized for each viroid. PBCVd was 99% identical with the P47A isolate variant 9 (GenBank Accession No. Y18043); PLMVd shared 85 to 96% identity with the PC-C32 Italian isolate of PLMVd from peach (GenBank Accession No. AJ550905), and HSVd shared 99 to 100% identity with the HSVd from dapple plum fruit (GenBank Accession No. AY460202). To our knowledge, our investigation reports for the first time, the occurrence of PLMVd, PBCVd, and HSVd infecting fruit trees in Tunisia, stressing the need for a certification program to aid in prevention and spread of fruit tree viroids in this country.

Abstract
A real-time fluorescent reverse-transcriptase polymerase chain reaction (RT-PCR) assay using a short fluorogenic 3' minor groove binder (MGB) DNA hydrolysis probe was developed for the detection of Prunus necrotic ringspot virus (PNRSV) in stone fruit trees. The covalent attachment of the minor groove binder moiety at the 3' end of the probe increased the probe target duplex stability and raised the melting temperature to a range suitable for real-time analysis. The real-time RT-PCR assay correlated well with conventional RT-PCR results for the detection of PNRSV. This assay reliably detects PNRSV in bark tissues of dormant cherry and plum trees. Furthermore, it is well adapted for the routine detection of PNRSV because it eliminates one risk of contamination by performing the whole test in a single closed tube. This system may replace the commonly used diagnostic techniques (e.g., woody indicators and immunological tests) to detect this virus.
