Epidemiológiai körkép: a krónikus vesebetegségek és a vesepótló kezelések gyakorisága
Authors: Kulcsár Imre
Published: May 2024

A szerző nemzetközi és hazai adatok alapján bemutatja a krónikus vesebetegek számának dinamikus növekedését, és a végállapotú vesebetegek ellátásának növekvő terheit (vesepótló kezelések, hospitalizáció, magas halálozási kockázat – amely utóbbiak jelentős egészségügyi költségnövekedéssel járnak). Fontosnak tartja a betegség korai diagnózisát és adekvát konzervatív kezelését. Magyarországon a krónikus vesebetegek számát körülbelül 1,5 millióra becsülik. A vesepótló kezelésre kerülő (incidens) betegek száma évente 4500-5000 fő, nagyobb hányadukat az akut esetek jelentik. A krónikus vesebetegek közül vesepótló kezelésre kerülők (incidens), illetve az adott év végén is kezelt (prevalens) betegek számát illetően a magyar adatok európai szinten relatíve magasabbak. Peritonealis dialízisben kezelt betegeink száma magasabb az európai (ERAEDTA) átlagnál. Transzplantáció vonatkozásában nem vagyunk lemaradásban. Dialízisellátó helyeink száma relatíve kevés és a dialízisellátás szerkezete is bővítendő.

Published: May 2024

A vesepótló kezelésre szoruló betegek számának növekedésével a peritonealis dialízist (PD) igénylő betegek száma is növekszik. A hasi dialízis valójában egy effektív és jól tolerálható vesepótló kezelés a vesebetegségek széles spektrumában, az életkortól függetlenül, akár idős betegek számára is. A PD költséghatékonyabb dialízismódszer és a reziduális vesefunkció megőrzésében is jelentősebb szerepe van a hemodialízishez képest, ami kiemelkedő fontosságú a PD-kezelt betegek túlélése szempontjából. Mindezek miatt remélhetőleg a hasi dialízis alkalmazása még szélesebb körben fog elterjedni a mindennapi betegellátásban és ezáltal valószínűleg az alapellátó orvosok és más társszakmában dolgozó kollégák is egyre gyakrabban találkozhatnak majd PD-kezelt páciensekkel. Összefoglalónk célja, hogy ezen vesepótló kezelési modalitás alapvető kezelési elveit jobban megismerje az olvasó és ezáltal a hasi dialíziskezelést az általános belgyógyászati gondolkodás részévé tegyük.
A novel performance adaptation method for aero-engine matching over a wide operating range
Authors: Wang Ye , Wang Zepeng , Wang Xizhen , Zhao Bokun , Zhao Yongjun
Published: May 2024

High-fidelity performance modelling is crucial for the development of aero-engine digital twin technology. The accuracy of component-level models heavily relies on the precision of characteristic maps, and inaccuracies in these maps can cause significant deviations between predicted and actual engine performance. A novel method of aero-engine performance adaptation based on adaptation factor surfaces is proposed, which aims to provide a performance matching method for aero-engines over a wide operating range. To improve the convergence and stability of the solution, a hybrid algorithm is proposed that fuses model and measured data to calculate the adaptation factor at the operating points. The modification of the characteristic maps is achieved in both directions by means of adaptation factor surfaces. The method is validated by simulating two engines with distinct maps, and the results show that the method significantly improves the model accuracy at the component level under widely varying operating conditions, taking into account the multidimensional aspects of the maps and the differences between the real engine and the model. The proposed approach has the potential to improve the accuracy and efficiency of digital twin technology for aero-engines.

Published: May 2024

Local gravestone (Pilsbryconcha exilis) is an animal that lives in fresh waters such as rivers, lakes, and other waters. The survival of local mussels is very high so that in large quantities it can be used as a water purification process due to pollutants and heavy metal pollution. Cyanide is commonly used to extract gold ore, waste that is wasted in waterways contains a lot of CN compounds so that it can pollute the living things in it. The purpose of this study was to determine the potential of local gravestone (Pilsbryoconcha exilis) as a biofilter to decrease cyanide (CN) levels. This study consisted of three treatments and one control (without KCN) with one replication. The number of mussels in each treatment amounted to 10 tails with the concentration of cyanide used was 0.04; 0.07; and 0.1 ppm. The results of this study indicate that local gravestone can affect the decrease in cyanide levels in the experimental aquarium media. In the treatment with KCN concentration of 0.07 ppm there was a decrease in cyanide levels of 0.011 mg/L and the treatment with 0.1 ppm KCN concentration decreased cyanide levels of 0.025 mg/L. The survival rate of the mussel during the research process was 100%, because there were no local dead mussels found. The best daily growth rate was in treatment 3 with 0.1 ppm KCN concentration of 2.3%.

Authors: Wicaksono Arif , Hernina Revi
Published: May 2024

This study aims to cluster sub-districts (kelurahan) in Bogor Municipality based on greenness level.  Normalized Difference Vegetation Index (NDVI) values were processed from Landsat 8 OLI recorded on 24 May 2020, downloaded from United States Geological Survey (USGS) website.  NDVI values greater than 0,3 indicate that vegetation pixels are separated from overall raster maps.  These NDVI values over 0,3 were extracted based on each sub-district poligon within Bogor Municipality.  For sub-districts with NDVI 0,3, the percentage of the area and NDVI mean values were generated using Geographic Information System (GIS).  In order to cluster 68 sub-districts in Bogor Municipality, two variables of NDVI, namely area percentage and mean NDVI values, were processed using the Fuzzy C Means (FCM) method.  Greenness level clustering using the FCM method shows 14 sub-districts in high class, 28 in medium class, and 26 in low cluster class. Overlay analysis among clusters shows two sub-districts (7.69%) in the low cluster class inside the medium class, one sub-district (3.57%) in the medium class within the low class, and one sub-district (7.14%) in the high cluster class inside the medium class. There are two main indications for an overlapping sub-district located in multiple clusters, namely the sub-district that has little different values with neighbouring cluster centres, and the sub-district that has similar different values with two cluster centres.

AIM: the optimal extent of adhesiolysis for stoma takedown after Hartmann’s procedure is still unknown. This study is for evaluation the early and late results after partial and total dissection of adhesions during Hartmann’s reversal (HR).PATIENTS AND METHODS: a prospective non-randomized study included 99 patients with end colostomy. Fifty patients were included in the main group, in which partial adhesiolysis was performed during HR, and 49 — were the control group, in which complete dissection of adhesions was performed. The groups did not differ in the basic demographic characteristics, number of previous operations, and the severity of the adhesions.RESULTS: the operation time in the groups of partial and total adhesiolysis was 222 vs 205 minutes, respectively (p = 0.9). Injury of the intestinal wall occurred in 18 patients in the main group, and in 19 controls (p = 0.8). The postoperative stay was 12 in the main group vs 11 in the control (p = 0.7). The morbidity rate in the main group was 42% (n = 21), in controls — 29% (n = 14) (p = 0.2). Reoperations were performed in 4 patients of the main group, no reoperations in the control group were required, but no significant differences were obtained (p = 0.5). In the group of partial adhesiolysis, 1 fatal outcome was registered. By the regression analysis, the only factor increasing the likelihood of postoperative complications was a BMI > 35 kg/m2 (OR = 5.3; 95% CI: 1.5–21.2; p = 0.01).CONCLUSION: total adhesiolysis does not affect the operation time and traumatism of Hartmann reversal, does not increase morbidity rate.

AIM: to develop ultrasound semiotics of solitary rectal ulcer (SRU).PATIENTS AND METHODS: fifty-eight patients with a histologically verified SRU were included in the retrospective study. All patients underwent colonoscopy and transrectal ultrasound (TRUS). Changes in rectal wall detected by TRUS were compared with colonoscopy data.RESULTS: On TRUS SRU is represented by a significantly thickened rectal wall (median thickness of the rectal wall in the region of SRU is 9 (7–10) mm and 5 (4–6) mm outside, p < 0.001), most often with a predominance of muscular and submucosal layers (46/58, 79%). The structure and echogenicity of these layers are changed: the connective tissue layer is visualized in muscular layer (51/58, 88%), submucosal layer is hypoechogenic (47/58, 81%), boundaries between rectal wall layers are faded (50/58, 86%). Ulcers in SRU are characterized by presence of areas where the mucous layer cannot be traced (sensitivity 100%, specificity 95%), its extent is comparable to extent of ulcers detected on colonoscopy (p = 0.528). Polypoid SRU is characterized by local thickening of the mucosa (sensitivity 89%, specificity 95%). TRUS location of the SRU in height (p = 0.644) is comparable with colonoscopy data.CONCLUSION: the study determined general ultrasound signs of SRU and made it possible to differentiate macroscopic forms of SRU from each other with TRUS.

AIM: to assess the postoperative complications rate in the groups with intra- and extracorporeal ileotransverse anastomosis in laparoscopic right colectomy.PATIENTS AND METHODS: a single-center, randomized, non-inferiority trial was conducted with intention-to-treat data analysis. There were two groups of patients in whom performed laparoscopic right colectomy using a standardized technique. In the main group (n = 39) intracorporeal ileotransverse anastomosis (IA) was formed, in the comparison group — extracorporeal anastomosis (EA) (n = 40).RESULTS: the operation time in the IA group was 192.4 ± 62.3, and in the EA group — 144.1 ± 41.3 minutes (p = 0.0002). The time of anastomosis formation was also significantly different: 53 (35; 71) minutes in intracorporeal and 30 (26; 35) minutes inn extracorporeal methods (p < 0.0001). The morbidity rate was not significantly different (25.6% vs 27.5%; p = 0.95). In the main group it was 25.6%, and in the control group 27.5% (p = 0.95). Postoperative hospital stay in the main group was significantly less — 5 vs 7.3 days in the comparison group (p < 0.001).CONCLUSION: the randomized trial demonstrated that IA is safe and comparable to EA in terms of the morbidity rate, despite its longer operation time. At the same time, in the IA group, patients achieved discharge criteria earlier, which reduced postoperative hospital stay.

AIM: to find histological prognostic factors for survival in patients with anorectal melanoma.PATIENTS AND METHODS: single center retrospective study of histological specimens of patients with anorectal melanoma (2005-2023). A revision of histological specimens was carried out, using the following criteria: multifocal growth, maximum tumor size, maximum thickness by Breslow, ulceration, perineural and lymphovascular invasion, as well as depth of invasion. Statistical processing was carried out using the Cox regression.RESULTS: twenty-one patients were included in the study. In all patients, treatment started with surgery: 13 (61.9%) — abdominoperineal excision (APE); 8 (28.1%) — local excision). The sample contained patients with the following initial stages of the process: IB–IIB — 12 (57.1%); III — 9 (42.9%). Nine (42.9%) patients developed local recurrence, and 8 (38.1%) — distant metastases. On univariate analysis, DFS was significantly affected by ulceration RR 0.061 (CI 95.0%; 0.004–0.097, p = 0.048), there was a trend towards the role of neurotropism RR 3.654 (CI 95.0%; 0.934–14.297, p = 0.063) and pigmentation RR 2.485 (CI 95.0%; 0.832–7.424, p = 0.103). In multivariate analysis, none of the criteria had a significant effect on DFS. On OS in univariate analysis was a trend towards an effect of Breslow invasion depth of more than 2 cm HR 1.028 (CI 95.0%; 0.998–1.060, p = 0.070) and depth of tumor invasion HR 2.117 (CI 95.0%; 0.990–4.525, p = 0.053). In multivariate analysis, none of the criteria had a significant effect on OS.CONCLUSION: evaluation of the effectiveness by histological features of skin melanoma showed the potential use of neurotropism, Breslow invasion of more than 2 cm and depth of tumor invasion as factors of unfavorable impact on DFS and OS in ARM. More trials are needed.

Radiation exposure poses a significant threat to human health. Emerging research indicates that even low-dose radiation once believed to be safe, may have harmful effects. This perception has spurred a growing interest in investigating the potential risks associated with low-dose radiation exposure across various scenarios. To comprehensively explore the health consequences of low-dose radiation, our study employs a robust statistical framework that examines whether specific groups of genes, belonging to known pathways, exhibit coordinated expression patterns that align with the radiation levels. Notably, our findings reveal the existence of intricate yet consistent signatures that reflect the molecular response to radiation exposure, distinguishing between low-dose and high-dose radiation. Moreover, we leverage a pathway-constrained variational autoencoder to capture the nonlinear interactions within gene expression data. By comparing these two analytical approaches, our study aims to gain valuable insights into the impact of low-dose radiation on gene expression patterns, identify pathways that are differentially affected, and harness the potential of machine learning to uncover hidden activity within biological networks. This comparative analysis contributes to a deeper understanding of the molecular consequences of low-dose radiation exposure.

Background

Digital radiography (DR) is a common and widely available examination. However, spinal DR cannot detect bone marrow edema, therefore, determining vertebral compression fractures (VCFs), especially fresh VCFs, remains challenging for clinicians.

Methods

We trained, validated, and externally tested the deep residual network (DRN) model that automated the detection and identification of fresh VCFs from spinal DR images. A total of 1,747 participants from five institutions were enrolled in this study and divided into the training cohort, validation cohort and external test cohorts (YHDH and BMUH cohorts). We evaluated the performance of DRN model based on the area under the receiver operating characteristic curve (AUC), feature attention maps, sensitivity, specificity, and accuracy. We compared it with five other deep learning models and validated and tested the model internally and externally and explored whether it remains highly accurate for an external test cohort. In addition, the influence of old VCFs on the performance of the DRN model was assessed.

Results

The AUC was 0.99, 0.89, and 0.88 in the validation, YHDH, and BMUH cohorts, respectively, for the DRN model for detecting and discriminating fresh VCFs. The accuracies were 81.45% and 72.90%, sensitivities were 84.75% and 91.43%, and specificities were 80.25% and 63.89% in the YHDH and BMUH cohorts, respectively. The DRN model generated correct activation on the fresh VCFs and accurate peak responses on the area of the target vertebral body parts and demonstrated better feature representation learning and classification performance. The AUC was 0.90 (95% confidence interval [CI] 0.84–0.95) and 0.84 (95% CI 0.72–0.93) in the non-old VCFs and old VCFs groups, respectively, in the YHDH cohort (p = 0.067). The AUC was 0.89 (95% CI 0.84–0.94) and 0.85 (95% CI 0.72–0.95) in the non-old VCFs and old VCFs groups, respectively, in the BMUH cohort (p = 0.051).

Conclusion

In present study, we developed the DRN model for automated diagnosis and identification of fresh VCFs from spinal DR images. The DRN model can provide interpretable attention maps to support the excellent prediction results, which is the key that most clinicians care about when using the model to assist decision-making.
Examining the ability of palm kernel shell extract to control corrosion and assess its economic value on thermo-mechanically treated steel in artificial seawater: a sustainable and environmentally friendly approach

Each year, the rising demand for palm oil generates large amounts of palm kernel shell waste. Discarded palm kernel shells can produce activated carbon, crushed shells, liquified fumes, and other derivatives; however, their indiscriminate disposal persists, raising issues related to the environment and economy. Therefore, the purpose of this study is to investigate the use of palm kernel shell as a corrosion inhibitor for thermo-mechanically treated steel in a seawater environment using gravimetric and electrochemical techniques, as well as surface tests at varying concentrations. The findings demonstrated that the palm kernel shell inhibited the cathodic and anodic processes by adsorption on the steel surface, which followed the Langmuir adsorption isotherm. The inhibitor exhibited a 98% inhibitory efficiency at 500 ppm concentration. Scanning electron microscopy analysis verified the thin films of the inhibitor on steel surface in seawater solution. Fourier transform infrared spectroscopy results show that the extract’s components prevent the steel corrosion through an adsorptive mechanism. According to the inhibitor economic evaluation, employing the palm kernel shell extract is less expensive than utilizing conventional inhibitors.

Published: May 2024

The climatic characteristics of tropical cyclones affecting Qingdao, China, were analyzed from the aspects of frequency, period, and intensity of the tropical cyclones and their impact on rainfall in Qingdao by referring to the Typhoon Yearbook, the tropical cyclone data of China during 1949–2020 as well as surface meteorological observations. The results showed that the frequency of tropical cyclones affecting Qingdao during 1949–2020 took on an overall decreasing trend and mostly exhibited a significant variation period of 2–4 year. Tropical cyclones with the track of turning after landfall and continuing northward after landfall accounted for 47.9%. In July, there were tropical cyclones mainly followed tracks of continuing northward after landfall, and tracks turning after landfall mostly occurred in September. The intensity of the tropical cyclones showed an overall weakening feature with distinct inter-decadal variations, and it did not change much when the northward tropical cyclones close affecting Qingdao. The different track of tropical cyclones had spatially heterogeneous, strong rainfall in Qingdao with the track of continuing northward after landfall brought the highest daily and process rainfall to Qingdao, while the tropical cyclones turning nearshore or advancing offshore before landfall had relatively little rainfall.
