Authors: Aleysa Mohammad , Simon Marc-René , Meriee Souha
Published: February 2023

Im Bereich der Wärme, vor allem im privaten Sektor, gilt Biomasse als der wichtigste Energieträger der erneuerbaren Energien. Am häufigsten kommt sie für die Bereitstellung von Warmwasser für Raumwärme und Trinkwasser zum Einsatz, in den vergangenen Jahren vermehrt in Kombination mit Solarthermieanlagen. Doch es besteht weiterhin Optimierungsbedarf. Durch eine verbesserte Steuerung der Kessel innerhalb des gesamten Energiebereitstellungssystems sowie einer abgestimmten Kommunikation zwischen den an dem Energieversorgungssystem beteiligten Akteuren (Energieerzeugungsanlage(n), Wärmespeichersystem, Gebäude und sonstige einflussreiche Faktoren) könnten maßgeblich Wärmeverluste, Brennstoff und Emissionen eingespart werden.

Syzygium albumis a critically endangered species, and the wood basic properties haven’t been reported. Therefore, this paper analyzes the wood from the anatomical characteristics, physical properties, and secondary components.The results showed thatobserved S. albumwood of a 46-year-old tree is diffuse-porous to semi-diffuse-porous wood. The maximum vessel tangential diameter is 127.47μm, which is found at the beginning of the earlywood. Thewood rays are heteromorphic type I and II, and the multi-column part is mostly 3 cells wide. In physical properties, the air-dry density is classified as "heavy", whereas its air-dry and full-dry differential dry shrinkage are "small" and "medium", respectively. This indicates that the wood performs better when dried. The content of benzene-ethanol extract from S. albumwood is 2.10%. The benzene-ethanol extracts were analyzed by GC-MS, and the main components are 2,6,11,15-tetramethylhexadecane (3.29%), eicosamethyl cyclodecasiloxane (10.02%), octadecamethyl cyclononasiloxane (7.43%), and tetracosamethyl cyclododeca-siloxane (3.60%), etc.

This work assessed how to remove ligninof palm oil empty fruit bunch (EFB) in environmentally friendly method and less energy. Moreover, delignification was strengthened with additional H2O2to perform hydroxyl radical by microwave radiation in low NaOH solution of concentration up to 0.8 M, 10%. Setting on microwave, solution was heating up and cause delignification work more effective. Observation at black liquor showed that temperature was influence by microwave radiation duration while NaOH concentration affected total suspendedsolidincreasing. Optimally treated EFB at 0,2 M NaOH with effective lignin removal and holocellulose increasing reached 27% and 26%, respectively. Unfortunately, at higher NaOH concentration, the decomposition penetrated EFB interior, holocellulose and made lignin percentage high again. Therefore, EFB yield got less at higher NaOH concentration because more EFB was sludgy and lost during washing. XRD analysis showed the increasing crystallinity by 2.2%, closer to -cellulose. SEM showed successful impurities removal from EFB surface and Ca, Nb, Si, and Mg detected by EDS.

Published: February 2023

The effect of antenna design modification, paper substrates and relative electrical permittivity of background materials on the reflection coefficient of UHF RFID antennas was studied. Simulation software was used to modify the design and calculate the reflection coefficient of the antennas. By modifying the coupling of the dipole with the induction loop of the antennas, areduction of the simulated reflection coefficient was achieved compared to thecommercial antenna. The positive effect of antenna modification was also confirmed by measuring thereflection coefficient of antennas printed on paper by thermal transfer printing, placed on extruded polystyrene and particle board. The reflection coefficient of the modified antennas was lower when placed on extruded polystyrene, whose relative electrical permittivity was lower than particle board. After installing the memory chip to the antennas printed on paper and paperboard, the identification, reading and recording range of passive UHF RFID tags were measured after they were placed on thicker paperboard, extruded polystyrene and particle board. The positive effect of antenna modification on improving the communication quality of passive UHF RFID tags placed on background materials with a relative electrical permittivity of 2.4 to 6.7 wasconfirmed.

Published: February 2023

The addition of green tea leaves fractions < 0.315 mm as afiller to urea-formaldehyde resin to reduction of emission of formaldehyde from three-layer birch plywood was investigated. Moreover, other properties such as bonding quality and water resistance of plywood were investigated. It was found that green tea had an ability to absorb formaldehyde. This phenomenon was caused by phenolic compounds contained in green tea leaves. The addition of green tea in the amount of 20% and 25% resulted in a decrease in formaldehyde emission fromplywood comparing to the reference sample. Thebonding quality test showed that the addition of tea leaves as a filler did not affect thestrength properties of the tested bond lines.
THE POTENTIAL OF PRODUCING HIGH ADDED VALUE STRUCTURAL TIMBER FROM LAMELLAE WASTE. TEST RESULTS AND ANALYSIS
Authors: HORVÁTH DÉNES , FEHÉR SÁNDOR , BÁDER MÁTYÁS
Published: February 2023

The research was based on the analysis of the density, bending strength and modulus of elasticity of 100 oak lamellae generated as small-sized production waste. In this part of thestudy series, the test results were presented in detail and analysed, in particularly the density distribution. Correlations between some test results have been shown. The dynamic and static test results were also compared. Despite the poor quality lamellae, the average density of the sample set corresponds to literary values and the distribution of density is normal. Specimens with low density are unsuitable for further use. But the density alone cannot be used for classification. Between static and dynamic modulus of elasticity can be found a good relationship. The relationships between density and both static and dynamic modulus of elasticity of the specimens can be considered as good, too. The best correlation is in bending tests between the deflection of the specimens in the elastic range and the bending strength.

The study investigated morphology and thermal properties of cellulose/poly furfural alcohol (PFA) composites prepared from maize stalk through acid mixtures. The cellulose nanocrystals (CNCs) were extracted from maize stalk via acid hydrolysis using mixtures of various acids.The prepared CNCs were encapsulated in a PFA matrix via in situpolymerization process using p-toluene sulfonic acid as catalyst. The properties of untreated maize stalk, cellulose and their nanocomposites were analysed by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transmission infrared (FTIR) and thermogravimetric analysis (TGA). The crystallinity of maize stalk was generally increased after an acid hydrolysis dominated by H2SO4/HNO3 and H2SO4/HCl. The same trend was observed from TGA, except that H2SO4/H3PO4and H2SO4/HClO4dominated thermal stability trailed by H2SO4hydrolysed CNC nanocomposite. The surface breakage of fibers observed in SEM images was depended on the strength of acids used tohydrolysed the CNC. There was also evidence of aggregation and cracked PFA surface with addition of acid hydrolysed CNCs, dependent on the acids strength. The H2SO4/HClO4hydrolysed CNC/PFA displayed afairly good dispersion of CNCs in the PFA matrix with no surface breakage.

Elbow stiffness is a common problem following trauma to the elbow. Sixty-seven patients with post-traumatic elbow stiffness were surgically treated between 1985 - 2000. Sixty-one were clinically reviewed after a mean follow-up of 15 years (range: 7 to 19 years). The initial trauma had resulted in 8 intrinsic, in 31 extrinsic and in 28 mixed lesions. The mean preoperative flexion – extension arc of motion, was 46°. After an unsuccessful conservative treatment, open surgical arthrolysis was performed in 59 patients with exclusively extrinsic or mixed lesions, through a lateral approach combined with a medial approach when deemed necessary. In patients with complex intrinsic lesions here were 3 resection arthroplasties and 5 total elbow arthroplasties performed. At final follow-up, the mean arc of motion of the elbow was significantly improved to 100° in 56 patients who had undergone open arthrolysis; 3 were lost to follow-up. Among the 3 patients who had undergone arthroplasty resection, only one had a markedly improved elbow function with a 90° arc of motion; elbow stiffness had recurred in the other two patients. Of the 5 patients who underwent total elbow arthroplasty, 3 were lost to follow-up; the other 2 patients had a stable elbow, with a fair arc of motion of 60° and 70° respectively, both with a flexion contracture of 20°. Complications included 2 superficial infections, which healed following conservative treatment, and one fracture following remodelling of a malunited distal fracture of the humerus. In the treatment of the post-traumatic stiffness of the elbow, the arthrolysis and the arthroplasty are indicated in dependence on the existent (extrinsic or intrinsic) lesions and on their severity.

Published: February 2023

This study evaluates the envelope thermal performance of high-rise apartment buildings in Malaysia, which are being largely dominated due to the high economic development and increased population. The evaluation was conducted using the Overall Thermal Transfer Value (OTTV), which is the key tool used in the Green Building Index to assess the Energy Efficiency of buildings. Different high-rise apartment buildings were selected with different architecture styles, to account for several periods of building construction. The OTTV value was calculated for the west-oriented façade of the selected buildings, which is considered as a critical orientation that receives high solar radiation. The results showed that four out of the five investigated buildings achieved the minimum requirements for the OTTV, i.e., less than 50 W/m². The maximum and minimum OTTV values with the buildings’ original design were 82.60 W/m² and 41.54 W/m², respectively. However, one of the buildings achieved a lower OTTV value with the installation of shading devices by the owners, i.e., decreased from 48.39 W/m² to 37.60 W/m². The solar radiation penetration through the fenestration was found to be the major contributor to the total OTTV, while it can be controlled by the shading devices. Besides, using dark paints increased the heat conduction through the opaque walls by more than double compared to light paints. This study shows that some design considerations, such as paint colour, shading devices, and glazing material, can have a great influence on the heat gain in buildings.

Published: February 2023

The present work investigates the exergy and effective efficiency of the multi-pass solar air collector with longitudinal fins by analysis approach and multi-objective optimization. The effect of 0.01-0.02 kg/s air flow rate, 15-35 mm collector depth, 1-3 m collector length, and 24.21-30.67 mm fin pitch was considered. The optimization was analyzed by the Preference Selection Index (PSI) method, with three maximum criteria: thermal efficiency, effective efficiency, and exergy efficiency. Mathematical models were solved by EES software. Results indicated that the multi-pass (TPLF and DPLF) type was better than the SPWF type by three criteria. The highest exergy efficiency of the TPLF and DPLF types was 6.696% and 5.636%. The greatest effective efficiency of the TPLF and DPLF types was 69.09% and 66.17%. Furthermore, the optimization results indicated that the three efficiency criteria of the DPLF type were 58.38%, 58.22%, and 4.491% for the best case; the three efficiency criteria of the TPLF type were 60.97%, 60.85%, and 5.439% for the best case. The worst configuration was the model with a short collector length, large collector depth, and large fin pitch. The collector efficiency decreased with decreased fin pitch for the configuration with the large collector length, short collector depth, and high mass flow rate.

Published: February 2023

Hyperlipidemia is a condition which comprises several acquired and genetic disorders that cause elevated lipid levels in the body. The elevated lipids may further lead to various health complications such as arteriosclerosis, cardiovascular disease, cerebrovascular and peripheral vascular diseases. A 41-year-old male, non-alcoholic, non-smoking, vegetarian, and self-employed patient reported with chronic abnormally high level of lipids. The patient was assessed on day 1, day 18 and after completion of 25 days of Ayurveda and naturopathy therapy for hyperlipidemia. In spite of suffering from hyperlipidemia, the patient was not having any associated complaints; therefore he was prescribed an integrated therapy of yoga, Ayurveda and Naturopathy. The results of present case report showed substantial reduction in cholesterol and triglycerides levels with three weeks of yoga, Ayurveda, and Naturopathy treatment. The patient was not prescribed any concomitant allopathic medications during the treatment period. The case study concluded that combined alternative therapies of yoga, Ayurveda and Naturopathy have helped in substantial reduction of abnormal levels of lipids in a short duration of three weeks.
A Statistical Analysis of Magnetic Field Changes in the Photosphere during Solar Flares Using High-cadence Vector Magnetograms and Their Association with Flare Ribbons
Authors: Yadav Rahul , Kazachenko M. D.
Published: February 2023

We analyze high-cadence vector magnetograms (135 s) and flare-ribbon observations of 37 flares from the Solar Dynamics Observatory to understand the spatial and temporal properties of changes in the photospheric vector magnetic field and their relationship to footpoints of reconnected fields. Confirming previous studies, we find that the largest permanent changes in the horizontal field component lie near the polarity inversion line, whereas changes in the vertical field are less pronounced and are distributed throughout the active region. We find that pixels swept up by ribbons do not always exhibit permanent changes in the field. However, when they do, ribbon emission typically occurs several minutes before the start time of field changes. The changes in the properties of the field show no relation to the size of active regions, but are strongly related to the flare-ribbon properties such as ribbon magnetic flux and ribbon area. For the first time, we find that the duration of permanent changes in the field is strongly coupled with the duration of the flare, lasting on average 29% of the duration of the GOES flare. Our results suggest that changes in photospheric magnetic fields are caused by a combination of two scenarios: contraction of flare loops driven by magnetic reconnection and coronal implosion.

Using ∼427 ks of Chandra observations, we present a study of shock heating and intracluster medium (ICM) cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roughly 50, 80, and 130 kpc from the center. The total energy associated with the shocks is ∼6 × 1061 erg, with the central active galactic nucleus (AGN) driving a pair of weak shocks every 20–30 Myr with a power P
sh ≈ 1046 erg s−1. Based on its morphology and age (∼30 Myr), the inner cocoon shock is associated with the four equidistant X-ray cavities previously discovered. From the thermodynamic analysis of the inner 30 kpc, we find evidence for ICM condensation into colder gas between and behind the X-ray cavities. The total AGN mechanical power (cavities and shocks) of 3.4 × 1046 erg s−1 can balance the ICM radiative losses, estimated as L
cool = 2.3 × 1045 erg s−1. By building plots of P
cav versus L
cool, P
shock versus L
cool, and P
tot versus L
cool for RBS 797 and 14 other galaxy clusters, galaxy groups, and elliptical galaxies where both cavities and shocks are detected, we verify that the most powerful outbursts are found in the strongest cooling systems. Ultimately, we observe that the mechanical power of the AGN exceeds the gas radiative losses by a factor that is different for FR I and FR II radio galaxies, being less than a few tens for FR Is (as RBS 797) and more than roughly 100 for FR IIs.

Published: February 2023

The quasar SDSS 0956 + 5128 exhibits three distinct velocity components with large offsets in emission: the systemic velocity of [O ii], [O iii], and [Ne iii] narrow lines have redshift z = 0.7142; the broad Mg ii line is shifted by −1200 km s−1 with respect to the narrow lines; the broad Hα and Hβ lines are at −4100 km s−1. We present new Hubble Space Telescope spectra of Lyα and C iv emission lines and high-resolution images of the quasar. The offsets of these lines are consistent with the velocity component of the Balmer emission, and the photometry in optical and near-infrared wavelengths does not show any signs of recent mergers in the host galaxy or irregularities in the location of the quasar. The data do not confirm predictions of the previous most likely hypotheses involving a special orientation and morphology of the quasar disk, such as in the recoiling black hole scenario, neither it is consistent with accretion disk winds. Instead, based on the cumulative evidence, we propose a new scenario, in which the broad-line region is in the state of outflow caused by a strong shock wave, with a supernova as a possible event for producing the shock ejecta.
Temporal and Latitudinal Variations in Ca-K Plage and Network Area: An Implication for Meridional Flows
Authors: Priyal Muthu , Singh Jagdev , Ravindra Belur , Sindhuja G.
Published: February 2023

The Ca-K spectroheliograms obtained at the Kodaikanal observatory are used to generate a uniform time series using the equal-contrast technique for studying the long- and short-term variations in the solar chromosphere. The percentages of plage, enhanced network, and active and quiet network areas at various latitudes is compared with the activity at 35° latitude and also with the sunspot number for the period of 1907–1984. The values of the phase differences indicate that the activity begins at ∼45° latitude and shifts progressively to a lower latitude at a speed of ∼9.4 m s−1 . The shift speed slows down gradually and reaches ∼3 m s−1 at ∼5° latitude. No phase difference between the variations of Ca-K activity at 55°, 65°, and 75° latitude belts implies that changes in the activity are happening simultaneously. The analysis shows that the activity at polar latitude belts is anticorrelated with the sunspot number. This study indicates that a multicell meridional flow pattern could exist in the latitude direction. One type of cell could transport the magnetic elements from mid- to low-latitude belts through meridional flows, and the other cell type could be operating in the polar region.

Published: February 2023

Neutrino-cooled accretion flow around a spinning black hole, produced by a compact binary merger, is a promising scenario for jet formation and launching magnetically driven outflows. Based on GW170817 gravitational wave detection by LIGO and Virgo observatories, followed by electromagnetic counterparts, this model can explain the central engine of the short-duration gamma-ray bursts and kilonova radiations. Using the open-source general relativistic magnetohydrodynamic HARM-COOL code, we evolved several 2D magnetized accretion disk–black hole models with a realistic equation of state in the fixed curved spacetime background. We applied the particle tracer technique to measure the properties of the outflows. The disk and black hole's initial parameters are chosen in a way to represent different possible postmerger scenarios of the merging compact objects. Our simulations show a strong correlation between the black hole's spin and ejected mass. Generally, mergers producing massive disks and rapidly spinning black holes launch stronger outflows. We observed our models generate winds with moderate velocity (v/c ∼ 0.1–0.2) and a broad range of electron fractions. We use these results to estimate the luminosity and light curves of possible radioactively powered transients emitted by such systems. We found that the luminosity peaks within the range of 1040–1042 erg s−1, which agrees with previous studies for disk wind outflows.

Evidence for the presence of ion cyclotron waves (ICWs), driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the joint observations performed by Parker Solar Probe and the Metis coronagraph on board Solar Orbiter, local measurements of the solar wind can be linked with the large-scale structures of the solar corona. The results suggest that the dynamics of the current sheet layers generates turbulence, which in turn creates a sufficiently strong temperature anisotropy to make the solar-wind plasma unstable to anisotropy-driven instabilities such as the Alfvén ion cyclotron, mirror-mode, and firehose instabilities. The study of the polarization state of high-frequency magnetic fluctuations reveals that ICWs are indeed present along the current sheet, thus linking the magnetic topology of the remotely imaged coronal source regions with the wave bursts observed in situ. The present results may allow improvement of state-of-the-art models based on the ion cyclotron mechanism, providing new insights into the processes involved in coronal heating.

We report near-infrared polarization of the zodiacal light (ZL) measured from space by the Diffuse Infrared Background Experiment (DIRBE) on board the Cosmic Background Explorer in photometric bands centered at 1.25, 2.2, and 3.5 μm. To constrain the physical properties of interplanetary dust, we use DIRBE Weekly Sky Maps to investigate the solar elongation (ϵ), ecliptic latitude (β), and wavelength (λ) dependence of ZL polarization. We find that the polarization of the ZL varies as a function of ϵ and β, consistent with observed polarization at λ = 550 nm. While the polarization dependence on wavelength at (ϵ, β) = (90°, 0°) is modest (increasing from 17.7% ± 0.2% at 1.25% μm to 21.0% ± 0.3% at 3.5 μm), the variation is more pronounced at the north ecliptic pole (23.1% ± 1.6%, 35.1% ± 2.0%, and 39.3% ± 2.1% at 1.25, 2.2, and 3.5 μm, respectively). The variation in ZL polarization with wavelength is not explained by either Rayleigh scattering or absorptive particles larger than 10 μm.

We characterise the complete mitochondrial genomes (mitogenomes) of Black rockfish (Sebastes melanops Girard, 1856; n = 1), Dark rockfish (Sebastes ciliatus Tilesius, 1813; n = 2) and Dusky rockfish (Sebastes variabilis Pallas, 1814; n = 2). The lengths of the mitogenomes are 16,405 bp for S. melanops, 16,400 bp for both S. ciliatus and 16,400 and 16,401 bp for S. variabilis. We examine these species’ phylogenetic relationships using 35 previously published rockfish mitogenomes, representing 27 species. We find that S. melanops is sister to a clade consisting of S. rubrivinctus, S. nigrocinctus, S. umbrosus and S. oculatus, whereas S. ciliatus and S. variabilis are sister to a clade consisting of S. norvegicus, S. viviparus, S. mentella and S. fasciatus. We were unable to separate S. ciliatus and S. variabilis using their complete mitogenomes.
Clostridium difficile toxins impact on rat colon smooth muscle reactivity
Authors: Vassilev Petar , Zaytseva Ekaterina , Ardasheva Raina , Turiyski Valentin
Published: February 2023

Aim: The present study was conducted in an attempt to find possible direct mechanisms of action of Clostridium difficile toxins A and B (TCdA and TCdB) on contractility of isolated rat intestinal smooth muscles, as the contractive pathways affected by the toxins and responsible for motility disorders remain unclear. 

Materials and methods: Adult male Wistar rats were used in our experiments. Longitudinal smooth muscle (SM) preparations of proximal colon were isolated and their contractile activity was isometrically registered. The samples were mounted in tissue baths and exogenously treated with acetylcholine (ACh), serotonin (5-HT), dopamine, norepinephrine, TCdA and TCdB. The potential of TCdA and TCdB to affect the action of these mediators on SM activity was examined. 

Results: The experiments have shown that exciting action of ACh and 5-HT on colonic contractility is enhanced by TCdA rather than TCdB. Conversely, relaxing effect of dopamine and norepinephrine on contractile activity of colonic SM is under impact of TCdB but not TcdA. TCdA has a stronger direct effect on in vitro SM sensitivity to ACh and 5-HT than TCdB.

Conclusions: TCdA and TCdB affect directly the contractile reactivity of isolated rat colon smooth muscle. TCdA has a stronger direct effect on smooth muscle sensitivity to acetylcholine and 5-HT than TCdB. Such a trend has not been established for dopamine and norepinephrine.

Introduction: Prognostic scores in patients with local peritonitis (LP) have not yet been studied exhaustively.

Aim: We, therefore, aimed in this study to evaluate the ability of several scoring systems to predict death in LP.

Materials and methods: A retrospective analysis including 68 patients with LP was conducted at Prof. Dr. Stoyan Kirkovich University Hospital in Stara Zagora from January 2017 to August 2021. Clinical and laboratory data needed for calculating the scoring systems were collected at admission or postoperatively. We compared the prognostic performance of WSES SSS, MPI, SIRS, and qSOFA using area under the receiver operation characteristics (AUROC) curves and bivariate correlation analysis.

Results: The observed mortality rate was 8.8%. Among all scores, MPI showed the best prognostic performance (AUROC=0.805, 95% CI 0.660–0.950). A threshold MPI >25 points permitted prediction of adverse outcome with a sensitivity of 66.7% and a specificity of 80.6%. The only significant correlation was found between outcome and MPI (p=0.012, r=0.302). 

Conclusions: The MPI has the ability to prognosticate mortality in patients with LP unlike WSES SSS, qSOFA and SIRS.
Free-gliding screw fixation in slipped capital femoral epiphysis: potentially growing im-plants for symptomatic and prophylactic pinning
Authors: Tserovski Stefan , Alexiev Venelin , Kehayov Raytcho
Published: February 2023

Introduction: In situ fixation is the gold standard for mild and moderate slipped capital femoral epiphysis (SCFE) cases. The condition is associated with a low percentage of avascular necrosis and chondrolysis.[1] The present study examines the postoperative femoral neck remodelling and implant elongation in cases of therapeutic and prophylactic in situ fixation using the free-gliding screw system. 

Aim: The aim of our study was to assess the postoperative femoral neck growth and evaluate the biomechanical evolution and complication’s rate for 19 therapeutic and 11 prophylactic in situ fixations with a free-gliding screw. 

Materials and methods: We measured the preoperative and postoperative articulo-trochanteric distance (ATD), alpha angle (α angle) and screw elongation in symptomatic hips and in contralateral hips with prophylactic fixation. We compared the radiographic param-eters of 30 hips. 

Results: ATD remains approximately the same for symptomatic cases, whereas it increases for prophylactic fixated hip. Screw elongates in both group with statistically higher value for the prophylactic group. The alpha angle remains pathological in these cases with a mean value of 67.12±4.62°, but decreases for group II. Screw elongates by a mean value of 3.14±2.74 mm for group I and 6.78±8.81 mm for group II.

Conclusions: Prophylactic in situ fixation with free-gliding screws does not affect the proximal femoral growth (ATD), and does not decrease the alpha angle significantly. Screw elongates statistically in both groups, but more significantly for group II. For symptomatic hips, the in situ fixation allows the femoral neck to grow with ATD preserved, but significantly less than in group II. The alpha angle decreases but remains pathological.

Published: February 2023

Background/Aims: Little is known about the effect of Helicobacter pylori eradication on the recurrence of gastric hyperplastic polyps after endoscopic resection. Thus, we evaluated the recurrence rate of gastric hyperplastic polyps based on H. pylori eradication following endoscopic resection.Methods: We retrospectively reviewed the medical records of 201 patients with H. pylori infection who underwent endoscopic resection for gastric hyperplastic polyps at six medical centers. H. pylori status was assessed by histological analysis and a rapid urease test. A total of 149 patients underwent successful H. pylori eradication (eradication group), whereas 52 patients had persistent H. pylori infections (non-eradication group). The recurrence rate of gastric hyperplastic polyps and the risk factors according to H. pylori status were analyzed.Results: During the mean follow-up period of 18.3 months, recurrent gastric polyps developed after endoscopic resection in 10 patients (19.2% [10/52]) in the non-eradication group and 12 patients (8.1% [12/149]) in the eradication group. The cumulative incidence of recurrent gastric hyperplastic polyps was significantly higher in the non-eradication group than in the eradication group (p = 0.041, log‐rank test). In the adjusted analysis, H. pylori eradication reduced the recurrence of gastric hyperplastic polyps (hazard ratio [HR], 0.42; 95% confidence interval [CI], 0.18 to 0.99), whereas anticoagulation therapy increased the risk of recurrence of gastric hyperplastic polyps (HR, 4.91; 95% CI, 1.39 to 17.28).Conclusions: Successful eradication of H. pylori may reduce the recurrence of gastric hyperplastic polyps in patients after endoscopic mucosal resection.
Le commun dans la perspective biographique et la puissance du processus migratoire
Authors: Ozório Lúcia
Published: February 2023

S’inspirant de mes recherches avec les périphéries de la ville de Rio de Janeiro –notamment la favela de Mangueira, également connue comme communauté de Mangueira –, ce texte souhaite contribuer aux réflexions sur le commun dans la perspective biographique. Le débat porte sur la richesse des processus migratoires contemporains dans lesquels la résistance en tant que biopuissance tient un rôle indispensable dans la formation de nouvelles subjectivités. Ces processus incessants de déterritorialisation et de reterritorialisation affirment une immanence radicale à travers des modes multiples d’agir et d’être qui manifestent la non-acceptation de la violence des biopouvoirs et affirment la puissance de la vie (biopuissance). Ces modes uniques d’être et d’agir nous sont accessibles à travers notre dispositif de travail, la narration des histoires de vies en commun , que nous considérons comme un mode et un acte de subjectivation politique.
