Abstract
Background We examined the effect of intubation time and the lung mechanics on clinical outcomes in coronavirus disease 2019 (COVID-19) patients. Methods Based on the patient's hospital admission, intubation time was defined as early (≤ 2 days) or late (> 2 days). Patients were further divided into three groups; early (≤ 3 days), late (4 - 6 days), and very late (> 6 days) intubated. Results A total of 194 patients were included; 66.5% male, median age 65 years. Fifty-eight patients (29.9%) were intubated early and 136 (70.1%) late. Early intubated patients revealed lower mortality (44.8% vs. 72%, P < 0.001), were younger (60 vs. 67, P = 0.002), had lower sequential organ failure assessment (SOFA) scores (6 vs. 8, P = 0.002) and higher lung compliance on admission days 1, 6 and 12 (42 vs. 36, P = 0.006; 40 vs. 33, P < 0.001; and 37.5 vs. 32, P < 0.001, respectively). Older age (adjusted odds ratio (aOR) = 1.15, P < 0.001), intubation time (aOR = 1.15, P = 0.004), high SOFA scores (aOR = 1.81, P < 0.001), low partial pressure of oxygen (PaO2)/fractional inspired oxygen tension (FiO2) ratio (aOR = 0.96, P = 0.001), and low lung compliance on admission days 1 and 12 (aOR = 1.12, P = 0.012 and aOR = 1.14, P < 0.001, respectively) were associated with higher mortality. Very late and late intubated patients had higher mortality rates than patients intubated early (78.4% vs. 63.4% vs. 44.6%, respectively, P < 0.001). Conclusions Among COVID-19 intubated patients, age, late intubation, high SOFA scores, low PaO2/FiO2 ratio, and low lung compliance are associated with higher intensive care unit (ICU) mortality.

Abstract
Backgrounds Folate Hydrolase‐1 (FOLH1; PSMA) is a type II transmembrane protein, luminally expressed by solid tumour neo‐vasculature. Monoclonal antibody (mAb), J591, is a vehicle for mAb‐based brachytherapy in FOLH1+ cancers. Brachytherapy is a form of radiotherapy that involves placing a radioactive material a short distance from the target tissue (e.g., on the skin or internally); brachytherapy is commonly accomplished with the use of catheters, needles, metal seeds and antibody or small peptide conjugates. Herein, FOLH1 expression in primary (p) and metastatic (m) Merkel cell carcinoma (MCC) is characterized to determine its targeting potential for J591‐brachytherapy. Materials & Methods Paraffin sections from pMCC and mMCC were evaluated by immunohistochemistry for FOLH1. Monte Carlo simulation was performed using the physical properties of conjugated radioisotope lutetium‐177. Kaplan–Meier survival curves were calculated based on patient outcome data and FOLH1 expression. Results Eighty‐one MCC tumours were evaluated. 67% (54/81) of all cases, 77% (24/31) pMCC and 60% (30/50) mMCC tumours were FOLH1+. Monte Carlo simulation showed highly localized ionizing tracks of electrons emitted from the targeted neo‐vessel. 42% (34/81) of patients with FOLH1+/− MCC had available survival data for analysis. No significant differences in our limited data set were detected based on FOLH1 status (p = 0.4718; p = 0.6470), staining intensity score (p = 0.6966; p = 0.9841) or by grouping staining intensity scores (− and + vs. ++, +++, +++) (p = 0.8022; p = 0.8496) for MCC‐specific survival or recurrence free survival, respectively. Conclusions We report the first evidence of prevalent FOLH1 expression within MCC‐associated neo‐vessels, in 60‐77% of patients in a large MCC cohort. Given this data, and the need for alternatives to immune therapies it is appropriate to explore the safety and efficacy of FOLH1‐targeted brachytherapy for MCC. What's already known about this topic? We report the first evidence of prevalent folate hydrolase‐1 (FOLH1; also known as prostate‐specific membrane antigen) expression within MCC‐associated neovessels.
What does this study add? Herein, FOLH1 expression in Merkel cell carcinoma neovasculature is validated, and the therapeutic mechanism of specific, systemic targeting of disseminated disease with antibody‐based brachytherapy, is defined.

Abstract
Introduction. Resistance rates to azoles and echinocandins of Candida spp. increased over the last decade.Hypothesis/Gap Statement. Widespread use of antifungals could lead to development and dissemination of resistant Candida spp.Aim. To identify risk factors for isolation of Candida spp. non-susceptible to either fluconazole or echinocandins.Methodology. All patients hospitalized in the Intensive Care Unit (ICU) of the University General Hospital of Patras, Greece with Candida spp. isolated from clinical specimens during a ten-year period (2010-19) were included. Candida isolates were identified using Vitek-2 YST card. Consumption of antifungals was calculated.Results. During the study period, 253 isolates were included. C. non-albicans predominated (64.4 %) with C. parapsilosis being the most commonly isolated (42.3 %) followed by C. glabrata (nomenclatural change to Nakaseomyces glabrataa; 8.7 %) and C. tropicalis (11.9 %). Among all isolates, 45.8 and 28.5 % were non-susceptible and resistant to fluconazole, respectively. Concerning echinocandins, 8.7 % of isolates were non-susceptible to at least one echinocandin (anidulafungin or micafungin) and 3.1 % resistant. Multivariate analysis revealed that hospitalization during 2015-19, as compared to 2010-14, isolate being non-albicans or non-susceptible to at least one echinocandin was associated with isolation of fluconazole non-susceptible isolate. Administration of echinocandin, isolate being C. glabrata or C. tropicalis, or Candida spp. non-susceptible to fluconazole were independently associated with isolation of Candida spp. non-susceptible to at least one echinocandin. Fluconazole's administration decreased during the study period, whereas liposomal-amphotericin B's and echinoncandins' administration remained stable.Conclusion. Fluconazole's non-susceptibility increased during the study period, despite the decrease of its administration. Although echinocandins' administration remained stable, non-susceptibility among Candida spp. increased.

Abstract
Background Immunoglobulins (Igs) and cells of the innate and adaptive immune systems play a critical role in a host's response to sepsis. The aim of this study was to investigate the possible differences in the levels of Igs, white blood cells (WBCs), and T and B lymphocytes cells in relation to the microbiological and clinical responses of patients with sepsis or septic shock from carbapenem non-susceptible Gram-negative bacteria (CnS-GNB). Methods This pilot cohort study involved 24 hospitalized patients with sepsis or septic shock due to bacteremia from CnS-GNB. The microbiological and clinical responses of the patients were evaluated in relation to their blood levels of IgA, IgE, IgM and IgG, as well as WBCs and subpopulations of T and B cells upon sepsis diagnosis. A microbiological response was determined as clearance of bacteremia at 14 days of active antibiotic treatment for the isolated bacterial pathogen. Clinical response was defined as the resolution of all clinical and laboratory signs of infection and sepsis at 14 days of active antibiotic treatment for the isolated pathogen. Results From the 24 patients included in the study 18 (75%) and six patients (25%) presented and did not present microbiological response respectively, while 16 patients presented clinical response (64%) and eight patients (36%) did not have clinical response. The levels of the Igs did not show statistically significant differences between patients with sepsis from CnS-GNB bacteremia who exhibited microbiological or clinical response. There were also no statistically significant differences in the levels of WBCs and the subpopulations of T and B cells levels for these patients (P > 0.05). According to this pilot study, peripheral blood Igs and lymphocyte subpopulations levels do not affect the clinical and microbiological response of septic patients with bacteremia from CnS-GNB. Conclusions In patients with sepsis or septic shock from CnSGNB, there were no differences in the levels of Igs, circulating WBCs and T and B cells subpopulations between those with microbiological or clinical response and non-responders.

Abstract
Background: Tigecycline is a therapeutic option for carbapenemase-producing Klebsiella pneumoniae (CP-Kp). Our aim was to evaluate the impact of the tigecycline’s minimum inhibitory concentration (MIC) in the outcome of patients with CP-Kp bacteraemia treated with tigecycline monotherapy. Methods: Patients with monomicrobial bacteraemia due to CP-Kp that received appropriate targeted monotherapy or no appropriate treatment were included. Primary outcome was 30-day mortality. MICs of meropenem, tigecycline, and ceftazidime/avibactam were determined by Etest, whereas for colistin, the broth microdilution method was applied. PCR for blaKPC, blaVIM, blaNDM, and blaOXA genes was applied. Results: Among 302 CP-Kp bacteraemias, 32 isolates (10.6%) showed MICs of tigecycline ≤ 0.5 mg/L, whereas 177 (58.6%) showed MICs that were 0.75–2 mg/L. Colistin and aminoglycoside susceptibility was observed in 43.0% and 23.8% of isolates, respectively. The majority of isolates carried blaKPC (249; 82.5%), followed by blaVIM (26; 8.6%), both blaKPC and blaVIM (16; 5.3%), and blaNDM (11; 3.6%). Fifteen patients with tigecycline MIC ≤ 0.5 mg/L and 55 with MIC 0.75–2 mg/L were treated with tigecycline monotherapy; 30-day mortality was 20.0% and 50.9%, respectively (p = 0.042). Mortality of 150 patients that received other antimicrobials was 24.7%; among 82 patients that received no appropriate treatment, mortality was 39.0%. No difference in 30-day mortality was observed between patients that received tigecycline (MIC ≤ 0.5 mg/L) or other antimicrobials. Conclusion: Tigecycline monotherapy was as efficacious as other antimicrobials in the treatment of bloodstream infections due to CP-Kp isolates with a tigecycline’s MIC ≤ 0.5 mg/L.

Abstract
Viral vector mediated gene therapy has become commonplace in clinical trials for a wide range of inherited disorders. Successful gene transfer depends on a number of factors, of which tissue tropism is among the most important. To date, definitive mapping of the spatial and temporal distribution of viral vectors in vivo has generally required postmortem examination of tissue. Here we present two methods for radiolabeling adeno-associated virus (AAV), one of the most commonly used viral vectors for gene therapy trials, and demonstrate their potential usefulness in the development of surrogate markers for vector delivery during the first week after administration. Specifically, we labeled adeno-associated virus serotype 10 expressing the coding sequences for the CLN2 gene implicated in late infantile neuronal ceroid lipofuscinosis with iodine-124. Using direct (Iodogen) and indirect (modified Bolton-Hunter) methods, we observed the vector in the murine brain for up to one week using positron emission tomography. Capsid radioiodination of viral vectors enables non-invasive, whole body, in vivo evaluation of spatial and temporal vector distribution that should inform methods for efficacious gene therapy over a broad range of applications.

Abstract
BACKGROUND Guillain-Barré syndrome (GBS) is a heterogeneous condition that encompasses acute immune-mediated polyneuropathies. GBS is the most frequent cause of acute neuromuscular paralysis worldwide and constitutes one of the most serious emergencies in neurology. Description of case: As it presents extremely rarely with the first symptom being abdominal pain, herein we report the case of a 48-year-old man who presented with acute abdominal pain and diagnosed with GBS. The patient required mechanical ventilation for two weeks and was discharged one month later, after having had a tracheostomy and developed tetraplegia. CONCLUSION GBS should be included in the differential diagnosis of acute abdominal pain when other medical or surgical causes have been excluded. Hippokratia 2015; 19 (4): 374-375.

Abstract
Microfibrous palygorskite clay mineral and nanocrystalline TiO(2) are incorporating in the preparation of nanocomposite films on glass substrates via sol-gel route at 500°C. The synthesis involves a simple chemical method employing nonionic surfactant molecule as pore directing agent along with the acetic acid-based sol-gel route without direct addition of water molecules. Drying and thermal treatment of composite films lead to the elimination of organic material while ensure the formation of TiO(2) nanoparticles homogeneously distributed on the surface of the palygorskite microfibers. TiO(2) nanocomposite films without cracks consisted of small crystallites in size (12-16 nm) and anatase crystal phase was found to cover palygorskite microfibers. The composite films were characterized by microscopy techniques, UV-vis, IR spectroscopy, and porosimetry methods in order to examine their structural properties. Palygorskite/TiO(2) composite films with variable quantities of palygorskite (0-2 w/w ratio) were tested as new photocatalysts in the photo-discoloration of Basic Blue 41 azo-dye in water. These nanocomposite films proved to be very promising photocatalysts and highly effective to dye's discoloration in spite of the small amount of immobilized palygorskite/TiO(2) catalyst onto glass substrates. 3:2 palygorskite/TiO(2) weight ratio was finally the most efficient photocatalyst while reproducible discoloration results of the dye were obtained after three cycles with same catalyst. It was also found that palygorskite showed a positive synergistic effect to the TiO(2) photocatalysis.

Abstract
BACKGROUND Evidence suggests that soluble CD40-ligand (sCD40L) is elevated in coronary artery disease (CAD) and is released from activated platelets during the acute myocardial infarction (AMI). Although sCD40L is part of immune response, the mechanisms regulating its release in different disease states remain unknown. MATERIALS AND METHODS This study enrolled 596 subjects: 201 patients with stable CAD, 109 patients with AMI and 286 healthy controls. Circulating levels of sCD40L, interleukin-6 (IL-6), soluble vascular cell adhesion molecule-a (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS Patients with AMI (n = 109) had higher levels of sCD40L and IL-6 compared to both CAD (n = 201) (P < 0.01) and controls (n = 286) (P < 0.01), while CAD also had higher levels of sCD40L and IL-6 compared to controls (P < 0.01). Similarly, sICAM-1 and sVCAM-1 levels were higher in CAD and AMI compared to controls (P < 0.05). IL-6 was the only parameter independently associated with sCD40L in healthy individuals [beta (SE):0.491(0.096), P = 0.0001]. However, in CAD or AMI, only diabetes mellitus [beta (SE): 2.689 (1.082), P = 0.044 and beta (SE): 10.406 (3.215), P = 0.002, respectively] and smoking [beta (SE): 3.470 (1.111), P = 0.002 and beta (SE): 9.694 (2.478), P = 0.0001, respectively] (but not IL-6), were independently associated with sCD40L levels. CONCLUSIONS Both CAD and AMI are accompanied by increased levels of sCD40L in parallel with an elevation of proinflammatory cytokine IL-6 and adhesion molecules sVCAM-1 and sICAM-1. Diabetes mellitus and smoking (but not IL-6 or adhesion molecules) were the only factors independently associated with sCD40L levels in CAD and AMI patients.

Abstract
10663 Background: Addition of trastuzumab (Herceptin, H) to successive neoadjuvant taxane+anthracycline-based chemo in patients (pts) with HER-2 (+) breast cancer significantly increases the pathological complete response (CR) rates. PLD has considerably less cardiotoxicity compared to parent drug. The aim of the study was to evaluate the activity and safety of combining H with PLD and P as 1st-line chemo in HER-2 (+) MBC pts. Methods: Inclusion criteria were: histologically confirmed MBC or relapsed after adjuvant chemo, ≥1 measurable lesion, adequate organ function, ECOG-PS 0–1, left ventricular ejection fraction (LVEF) by MUGA ≥55% (reevaluated after cycles 3 and 6). HER-2 positivity was determined by IHC and confirmed with CISH. Chemo was administered as follows: H 6mg/kg (8mg/kg-1st cycle) infused over 90min, PLD 35mg/m2 over 1hr, and P 175mg/m2 over 3hrs on day 1, with prophylactic G-CSF, recycled every 3 weeks. In responders, H was administered as consolidation (6mg/kg/3wks) until disease progression. Results: From 10/2003–10/2005, 19 female HER-2 positive MBC pts were enrolled. Median age: 68 (range, 42–78). Metastatic sites were: lung 6, liver 1, bone 3, lymph nodes 11, soft tissue 5 [median: 2 (range, 1–4)]. Pts received a median of 6 (range, 1–8) for a total of 102 cycles. PLD was started at 35 mg/m2, but in pts with grade 3 hand-foot syndrome (HFS) dose was reduced by 25% (6 pts), or the drug was omitted for 1 cycle (1 pt). 17 pts completed 3–6 cycles and were evaluable for response, all treated patients were evaluable for toxicity. Response rates (RR) were 71%; CR 41%, PR 30%, SD 29%, with no PD. Two pts rendered operable had pCR. Toxicities were: HFS; grade 4: 1, grade 3: 6 (overall 37%), grade 3–4 neutropenia: 4, grade 3 anemia: 1, grade 3–4 mucositis: 2, and grade 2 alopecia: 19. Neither significant LVEF decline, nor symptomatic cardiac event was observed. It is too early to provide data on response duration, TTP, and OS, and these will be available at the meeting. Conclusions: H+P+PLD as 1st-line chemo in HER-2(+) MBC pts is a very active and well tolerated regimen with no significant morbidity/mortality. HFS was the most relevant toxicity. The study is ongoing. No significant financial relationships to disclose.

Abstract
The solution models of [Tyr3]octreotate (DPhe1-Cys2-Tyr3-DTrp4-Lys5-Thr6-Cys7-Thr8-COOH, disulfide bridged) (I), its analogs functionalized with an open chain tetraamine chelator, N4-[Tyr3]octreotate (II), and the N4-(Asp)2-[Tyr3]octreotate (III) peptide have been determined through 2D 1H NMR spectroscopy in DMSO. Chemical shift analysis has been performed in an attempt to elucidate structural changes occurring during attachment of the tetraamine to the peptide backbone. NMR-derived geometrical constraints have been used in order to calculate high resolution conformers of the above peptides. Conformational analysis of the three synthetic analogues, have shown that these somatostatin analoges adopt a predominant antiparallel beta-sheet conformation characterized by a beta-like turn spanning residues DTrp4 and Lys5 which is supported in the case of N4-(Asp)2-[Tyr3]octreotate and N4-[Tyr3]octreotate by medium range NOEs. These data indicate that the above-mentioned molecules adopt a rather constrained structure in the 4-residue loop Tyr3-Thr6. Additionally, the C-terminal of [Tyr3]octreotate, comprising Cys7 and Thr8, appears to form a turn-like structure manifested by characteristic side-chain NOEs between Lys5 and Thr8, which have not been detected for the other two compounds. These data are discussed in the light of previous structural data of Sandostatin (octreotide) and suggest that attachment of the N4-chelator and two Asp residues at the N-end of [Tyr3]octreotate impose considerable structural changes and affect the binding properties of these peptides. Indeed, the IC50 values determined during competition binding assays against the sst2 (somatostatin subtype 2 receptor) suggest that the presence of the N4 group enhances receptor affinity, while extension of peptide chain by two negatively-charged Asp residues impairs receptor affinity at approximately one order of magnitude.

Abstract
The "3 + 1" ligand system [SN(R)S/S combination] was applied in order to synthesize neutral mixed-ligand oxotechnetium complexes of the general formula 99mTcO[SN(R)S]/[S] as potential 5-HT1A receptor imaging agents. The complexes are carrying the 1-(2-methoxyphenyl)piperazine moiety, a fragment of the true 5-HT1A antagonist WAY 100635, either on the monodentate ligand [S] or on the tridentate ligand [SN(R)S]. The complexes MO[EtN(CH2CH2S)2] [o-MeOC6H4N(CH2CH2)2NCH2CH2S] (3), MO[o- MeOC6H4N(CH2CH2)2N(CH2)3N(CH2CH2S)2][PhS] (6) and MO[o-MeOC6H4N(CH2CH2)2N(CH2)3N(CH2CH2S)2] [PhCH2CH2S] (9), where M = 99mTc, were prepared at tracer level using 99mTc glucoheptonate as precursor. For structural characterization, the analogous oxorhenium (M = Re, 1, 4 and 7, respectively) and oxotechnetium (M = 99gTc, 2, 5 and 8, respectively) complexes were prepared by ligand exchange reactions. All products were characterized by elemental analysis and spectroscopic methods. Complexes 1, 4 and 7 were further characterized by crystallographic analysis. For 1, the coordination geometry about rhenium can be described as trigonally distorted square pyramidal (tau = 0.36), while for 4 and 7, as distorted trigonal bipyramidal (tau = 0.66 and tau = 0.61, respectively). The coordination sphere about oxorhenium in all complexes is defined by the SNS donor atom set of the tridentate ligand and the sulfur atom of the monodentate coligand. The structure of the 99mTc complexes 3, 6 and 9 was established by comparative HPLC using authentic oxorhenium and oxotechnetium samples. The binding affinity of oxorhenium compounds for the 5-HT1A receptor subtype was determined in rat brain hippocampal preparations (IC50 = 6-31 nM). Preliminary tissue distribution data in healthy mice revealed the ability of all three 99mTc complexes to cross the intact blood-brain barrier (0.49-1.15% ID at 1 min p.i.). In addition, complexes 6 and 9 showed significant brain retention. These promising results have demonstrated that the SNS/S mixed-ligand system can be used in the development of 99mTc complexes as potential 5-HT1A receptor imaging agents.
