Abstract

Background: Long-term outcomes of patients treated with helmet noninvasive ventilation (NIV) are unknown: safety concerns regarding the risk of patient self-inflicted lung injury and delayed intubation exist when NIV is applied in hypoxemic patients. We assessed the 6-month outcome of patients who received helmet NIV or high-flow nasal oxygen for COVID-19 hypoxemic respiratory failure. Methods: In this prespecified analysis of a randomized trial of helmet NIV versus high-flow nasal oxygen (HENIVOT), clinical status, physical performance (6-min-walking-test and 30-s chair stand test), respiratory function and quality of life (EuroQoL five dimensions five levels questionnaire, EuroQoL VAS, SF36 and Post-Traumatic Stress Disorder Checklist for the DSM) were evaluated 6months after the enrollment. Results: Among 80 patients who were alive, 71 (89%) completed the follow-up: 35 had received helmet NIV, 36 high-flow oxygen. There was no inter-group difference in any item concerning vital signs (N = 4), physical performance (N = 18), respiratory function (N = 27), quality of life (N = 21) and laboratory tests (N = 15). Arthralgia was significantly lower in the helmet group (16% vs. 55%, p = 0.002). Fifty-two percent of patients in helmet group vs. 63% of patients in high-flow group had diffusing capacity of the lungs for carbon monoxide < 80% of predicted (p = 0.44); 13% vs. 22% had forced vital capacity < 80% of predicted (p = 0.51). Both groups reported similar degree of pain (p = 0.81) and anxiety (p = 0.81) at the EQ-5D-5L test; the EQ-VAS score was similar in the two groups (p = 0.27). Compared to patients who successfully avoided invasive mechanical ventilation (54/71, 76%), intubated patients (17/71, 24%) had significantly worse pulmonary function (median diffusing capacity of the lungs for carbon monoxide 66% [Interquartile range: 47–77] of predicted vs. 80% [71–88], p = 0.005) and decreased quality of life (EQ-VAS: 70 [53–70] vs. 80 [70–83], p = 0.01). Conclusions: In patients with COVID-19 hypoxemic respiratory failure, treatment with helmet NIV or high-flow oxygen yielded similar quality of life and functional outcome at 6months. The need for invasive mechanical ventilation was associated with worse outcomes. These data indicate that helmet NIV, as applied in the HENIVOT trial, can be safely used in hypoxemic patients.

Abstract

A 3-m thick sediment sequence, found in a limestone mine located in the south of Italy at a depth of ca. 25–30 m from the current ground level, was investigated. Samples from 5 layers were analysed by X-ray diffraction, elemental analysis, Inductively Coupled Plasma Mass Spectrometry and micromorphology. Microbial DNA was analysed by 16S rRNA gene metabarcoding. The main mineral compounds found in the 5 layers were calcite (70–80%) and clay minerals in layers #1 and #5, goethite (75%) and hematite in layer #2, manganese (66%) and iron oxides in layer #3, and almost exclusively goethite in layer #4. Micromorphology data allowed to shed light in understanding whether these sediments formed by subsequent weathering of carbonates and silicates or by migration of soil sediments from the surface, or also by the accumulation of shallow marine sediments occurring between the middle Pliocene and the lower Pleistocene, when the extreme western sector of this area underwent strong subsidence. From the microbiological point of view, upon the 16S rRNA gene analysis, these 5 layers appear to cluster in three groups. Overall, such a distribution suggests that, both in the top (#1) and in bottom layers (#4 and #5), different communities would have undergone in situ reproduction and colonization exploiting metabolically the substrate, whereas the two mid layers would have received bacterial convection by passive transport of percolating waters. At the same time, micromorphological data show that each layer preserved its distinct features to be related to the environmental condition at the time of deposition. The chemical, mineralogical and micromorphological features of the layers and the known physiology of the microbial taxa thereby encountered highlight the possible role of the latter in elucidating the occurrence of certain mineral species as well as the biogeochemistry of elements like Mn and Fe in sediment layers.

Abstract

Background and purpose: The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2. Methods: Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group. Results: In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection. Conclusions: Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

Abstract

Frank J. Stevenson (1922–2015) was one of the scientists who dedicated their professional life to increase our understanding of the properties and functions of NOM. He can be certainly considered as a pioneer of NOM and HS research by exploring innovative approaches to the study of both bulk SOM and humus chemistry. For more than thirty years, he was among the most influential in pushing forward the frontiers and guiding the directions in these research areas, which encouraged the IHSS to dedicate this Special Issue to his memory.

Abstract

Pig slurry is a source of organic matter (OM) and nutrients, nevertheless nowadays its disposal represents a serious problem at national scale due to both the large volume to be managed (ca. 18 million m3 y-1) and the insufficient land on which it could be spread. Anaerobic digestion (AD) could solve this environmental issue as it allows converting organic residues into biogas, a renewable source of energy, and digestate, a by-product with enhanced fertilizer and amendment properties. This is particularly true when the AD is performed at the solid state where the more recalcitrant fraction of OM may be accumulated. In this study, we investigated the changes in the OM composition during AD at different percolate recirculation frequency, thus providing information on the agronomic potential of resulting digestate samples. Solid-state anaerobic digestion (S-SAD) of pig slurry and straw (3:1 w/w) was carried out for this purpose. To avoid inhibition phenomena caused by volatile fatty acids accumulation during S-SAD, percolate recirculation technology was adopted. Three tests were carried out using 1, 2 and 4 recirculations day-1, respectively. A control test (i.e., without percolate recirculation) was also performed. The initial mixture and digestate samples (control, 1S-SAD, 2S-SAD, 4S-SAD) were characterized by elemental (CHNS), thermogravimetric (TG) and differential thermogravimetric (DTG) analysis, pyrolysis coupled to gas chromatography and mass spectrometry (Py-GC/MS) and 13C nuclear magnetic resonance (13C NMR) spectroscopy. Preliminary results suggested an increase of the OM degradation due to percolate recirculation. In particular, among digestate samples, 4S-SAD showed the lowest C/N and O/C values, as well as the lowest TG weight loss between 250 and 350°C (WL1), the latter one due to the greater consumption of sugars and cellulosic materials. 2S-SAD and 4S-SAD exhibited also a slight enhancement of TG weight loss between 350 and 550°C (WL2), which may be ascribed to a relative enrichment in humic-like substances and non-hydrolyzable residues. As a result, the thermostability index (WL2/WL1), generally used to describe chemical changes induced by OM biotransformation, was highest for 4S-SAD, followed by 2S-SAD, 1S-SAD and the control. Pyrolysis products at 400°C were grouped into 8 families according to their chemical nature, i.e. aromatics (Ar), lignin-derived aromatics (Lig), polysaccharides (Ps), ketones, n-alkane/ene, fatty acids (FA), sterols and terpenoids and N-compounds. Digestate samples exhibited lower contribution of Ps (the lowest in 4S-SAD) and higher Ar and Lig contents (the highest in 4S-SAD), as compared to the initial mixture. Likewise, 13C NMR spectra of the digestates evidenced a preferential degradation of O-alkyl C. This was particularly true for 4S-SAD that showed also the lowest O-alkyl C/alkyl C ratio, commonly used as an index of OM stability. On the opposite, this ratio was highest for the sample with 1 recirculation day-1 (1S-SAD), indicating its low degradation degree. In conclusion, atomic ratios, thermostability index, O-alkyl C/alkyl C ratio and preliminary Py-GC/MS results consistently showed a positive effect of the highest number (4) of percolate recirculations per day on the degree of OM degradation, resulting in a more stable OM in the corresponding digestate.
