Pattern of Primary Resistance of Helicobacter pylori to Clarithromycin among Pediatric Patients from North-Eastern Romania

Background: Helicobacter pylori antibiotic resistance has increased worldwide and affects the effectiveness of current therapies. The recommended first-line empiric treatment should be tailored to the local clarithromycin resistance rate. This study aimed to determine the pediatric patient profile and rate of clarithromycin resistance for patients diagnosed with Helicobacter pylori by gastric biopsy. Methods: We studied 84 positive gastric samples for Helicobacter pylori. Positive results were confirmed by a rapid urease test and histopathological examination, with the type of gastritis established according to the Sydney System. Gastric biopsy samples were stored in RNA saver. Clarithromycin resistance was determined by a real-time polymerase chain reaction-based molecular assay after RNA-DNA extraction. Results: Of the 84 biopsy samples analyzed, 35 (41.6%) were resistant to clarithromycin. Clarithromycin resistance was found mainly in girls (80%) with a mean age of 15 years (range 6–17 years). The history of prior exposure to clarithromycin was 91.6%. The concordance between the histopathological examination and the PCR test was 100%. Conclusions: One in 2.4 children infected with Helicobacter pylori had a strain resistant to clarithromycin. This resistant strain may be a reason for treatment failure in Romanian children, yet this is uninvestigated. The high rate of bacterial resistance to this antibiotic among children indicates the need for susceptibility testing before therapy.
Impact of dimensionality reduction techniques on student performance prediction using machine learning

This study addresses the crucial issue of predicting student performance in educational data mining (EDM) by proposing an Adaptive Dimensionality Reduction Algorithm (ADRA). ADRA efficiently reduces the dimensionality of student data, encompassing various academic, demographic, behavioral, social, and health-related features. It achieves this by iteratively selecting the most relevant features based on a combined normalized mean rank of five feature ranking methods. This reduction in dimensionality enhances the performance of predictive models and provides valuable insights into the key factors influencing student performance. The study evaluates ADRA using four different student performance datasets and six machine learning algorithms, comparing it to three existing dimensionality reduction methods. The results show that ADRA achieves an average dimensionality reduction factor of 6.2 while maintaing comprable accuracy with other mehtods.
Current Uses and Future Perspectives of Genomic Technologies in Clinical Microbiology

Recent advancements in sequencing technology and data analytics have led to a transformative era in pathogen detection and typing. These developments not only expedite the process, but also render it more cost-effective. Genomic analyses of infectious diseases are swiftly becoming the standard for pathogen analysis and control. Additionally, national surveillance systems can derive substantial benefits from genomic data, as they offer profound insights into pathogen epidemiology and the emergence of antimicrobial-resistant strains. Antimicrobial resistance (AMR) is a pressing global public health issue. While clinical laboratories have traditionally relied on culture-based antimicrobial susceptibility testing, the integration of genomic data into AMR analysis holds immense promise. Genomic-based AMR data can furnish swift, consistent, and highly accurate predictions of resistance phenotypes for specific strains or populations, all while contributing invaluable insights for surveillance. Moreover, genome sequencing assumes a pivotal role in the investigation of hospital outbreaks. It aids in the identification of infection sources, unveils genetic connections among isolates, and informs strategies for infection control. The One Health initiative, with its focus on the intricate interconnectedness of humans, animals, and the environment, seeks to develop comprehensive approaches for disease surveillance, control, and prevention. When integrated with epidemiological data from surveillance systems, genomic data can forecast the expansion of bacterial populations and species transmissions. Consequently, this provides profound insights into the evolution and genetic relationships of AMR in pathogens, hosts, and the environment.
Quad-Polarized Diversity Hollow Cylindrical Dielectric Resonator Antenna

This communication investigates a new quad-polarized diversity dielectric resonator antenna (DRA). The HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {x}}$ </tex-math></inline-formula>, HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {y}}$ </tex-math></inline-formula>, TE<inline-formula> <tex-math notation="LaTeX">$_{02\delta + 1}$ </tex-math></inline-formula>, and TM<inline-formula> <tex-math notation="LaTeX">$_{02\delta }$ </tex-math></inline-formula> modes of the cylindrical DRA are utilized. For a solid cylindrical DRA, the TM<inline-formula> <tex-math notation="LaTeX">$_{02\delta }$ </tex-math></inline-formula>-mode frequency is lower than those of the HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {x,y}}$ </tex-math></inline-formula> and TE<inline-formula> <tex-math notation="LaTeX">$_{02\delta + 1}$ </tex-math></inline-formula> modes, which is an obstacle to the diversity design. In the central DR region, the E-field of the TM<inline-formula> <tex-math notation="LaTeX">$_{02\delta }$ </tex-math></inline-formula> mode is strong, but those of the HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {x,y}}$ </tex-math></inline-formula> and TE<inline-formula> <tex-math notation="LaTeX">$_{02\delta + 1}$ </tex-math></inline-formula> modes are relatively weak. Therefore, decreasing the relative permittivity of that region by introducing a hollow can increase the TM<inline-formula> <tex-math notation="LaTeX">$_{02\delta }$ </tex-math></inline-formula>-mode frequency, with much smaller effects on the HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{x,y}$ </tex-math></inline-formula> and TE<inline-formula> <tex-math notation="LaTeX">$_{02\delta + 1}$ </tex-math></inline-formula> modes. In this way, the frequencies of the DRA modes can be made closer to one another. A hollow cylindrical glass DRA is employed to demonstrate this idea. The broadside <inline-formula> <tex-math notation="LaTeX">${y}$ </tex-math></inline-formula>-polarized HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {x}}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">${x}$ </tex-math></inline-formula>-polarized HEM<inline-formula> <tex-math notation="LaTeX">$_{31\delta }^{\mathrm {y}}$ </tex-math></inline-formula> modes are excited through two groups of notched aperture pairs. These four apertures are equally fed to excite the horizontally polarized omnidirectional TE<inline-formula> <tex-math notation="LaTeX">$_{02\delta +1}$ </tex-math></inline-formula> mode. Finally, a probe is used to excite the vertically polarized omnidirectional TM<inline-formula> <tex-math notation="LaTeX">$_{02\delta }$ </tex-math></inline-formula> mode. The proposed quad-polarized DRA has a minimum isolation of 21.4 dB and a peak gain of 3.57 dBi across the operation band. Additionally, its radiation patterns exhibit symmetry.
The Effect of Automated Agents on Individual Performance Under Induced Stress

Induced stress is a phenomenon commonly experienced across different fields such as emergency services, healthcare, air traffic control, sports, and business - which necessitates the development of effective coping strategies and resilience for individuals or teams performing under pressure. This study aims to examine the effects of automated agents on individual performance during high-stress conditions. The design of these agents ensures they carry out identical tasks as participants based on predetermined frameworks. Participants underwent an experimentally designed task that aimed at inducing stress while measuring their performance amidst time pressure and auditory distraction. Results indicate that working with automated agents causes individuals to alter their approach by focusing narrowly on immediate concerns - making it challenging for them to consider several options or see broader contexts accurately. Regardless of ability level participants' performances were influenced by these automated agents. Future research will explore how these findings interact with physiological signals. This study highlights the importance of developing effective coping strategies and the potential impact of social factors on individual performance under induced stress.
Quantifying the consensus on anthropogenic global warming in the scientific literature

We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991–2011 matching the topics 'global climate change' or 'global warming'. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming. In a second phase of this study, we invited authors to rate their own papers. Compared to abstract ratings, a smaller percentage of self-rated papers expressed no position on AGW (35.5%). Among self-rated papers expressing a position on AGW, 97.2% endorsed the consensus. For both abstract ratings and authors' self-ratings, the percentage of endorsements among papers expressing a position on AGW marginally increased over time. Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research. 2013 Environ. Res. Lett. 8 024024
Does the dominant hand’s use affect the complication rates in prosthetic breast reconstruction?

Background Numerous studies have investigated risk factors for unfavorable outcomes in prosthetic breast reconstruction, such as obesity, perioperative radiotherapy, and acellular dermal matrix use. However, no reports have explored whether the use of the dominant hand influences complications in breast reconstruction. To address this gap in the literature, analyzed complication rates between the dominant and non-dominant sides after reconstruction.Methods We retrospectively reviewed the charts of 160 patients (170 breasts) who underwent breast reconstruction from February 2017 to March 2022. We analyzed the complications between beasts on the dominant and non-dominant sides according to the reconstruction method.Results During prosthetic breast reconstruction, the drainage volume and duration on the dominant side exceeded those on the non-dominant side after reconstruction (duration: 9.79 days on the dominant side vs. 9.12 days on the non-dominant side, P=0.196; volume: 771.1 mL on the dominant side vs. 654.3 mL on the non-dominant side, P=0.027). The incidence of complications such as wound dehiscence, mastectomy flap necrosis, and infection was significantly higher in the dominant hand group (infection: 6 vs. 0, P=0.014; dehiscence: 15 vs. 4, P=0.009; flap necrosis: 13 vs. 4, P=0.024). Conclusions Complications including seroma, infection, and mastectomy skin flap necrosis following prosthetic reconstruction were common in breasts on the dominant-hand side. Therefore, meticulous management and restriction of shoulder movement can aid in preventing seroma-related complications in prosthetic breast reconstruction, especially on the side of the dominant hand.
Influence of biochar use on sugarcane growth, soil parameters, and groundwater quality

This study deals with the influence of biochar use on sugarcane growth and nitrate-nitrogen percolation losses, as well as chemical and physical properties of Shimajiri maji soil. Two varieties of biochars, biosolids and bagasse (residues of sugarcane stalks after juice extraction), were mixed with Shimajiri maji soil. Changes in nitrate-nitrogen concentration in percolating water, specific gravity, and available soil moisture before sugarcane planting and after harvest were investigated. Indices of sugarcane growth (stem diameter and length), Brix, and yield of estimated available sugar in each plot were estimated. Results indicated that bagasse charcoal reduced soil dry density and increased available moisture of Shimajiri maji soil. Maintaining suitable soil water content increased yields and sugar content of sugarcane, while nitrate-nitrogen concentration in percolating water also decreased. Hence, bagasse charcoal use may reduce nitrogen loads in Shimajiri maji soil.
Assessing the impacts of habitat fragmentation and subsequent anthropogenic expansion on the behavioural, nesting and population ecology of the estuarine crocodile, Crocodylus porosus

The project sought to examine the effects of habitat loss and fragmentation on the ecology and population genetics of the estuarine crocodile (Crocodylus porosus). Additionally, the role played by humans in this anthropogenically-altered landscape was examined. Through the utilisation of a host of technologies, some previously established, some completely novel in crocodilian research, a new insight into how the landscape is utilised by these cryptic predators was developed. This project represents a first detailed look at Sabah’s crocodilian population, as well as being the first active crocodile research carried out in Sabah’s longest river. Male crocodiles were found to adhere to one of two behavioural strategies, territorial and nomadic, mirroring findings of Campbell et al. (2013). Territory sizes were, however, found to be smaller than those described in Australia, this was attributed to increased prey availability and ecosystem productivity. Only two females were tagged and appeared to also display differences in behavioural strategy. However, due to the small sample size, further work is required to confirm this. Both males and females were found to avoid barriers and were unwilling to pass beyond the barrier, despite no physical obstruction. Nests were detectable aerially through the use of drones and medium-large scale surveys shown to be feasible. Nests were found to all display a number of similarities in terms of habitat characteristics, allowing for refined modelling of survey locations. This allows for a larger survey area to be completed given a limited number of flights, highlighting its cost effectiveness versus traditional methods of nest surveying. Genetic analysis suggested that there was no evidence of a genetic bottleneck following the population recovery that has occurred over the last 30 years. Geographically indistinct haplogroups were discovered, as well as limited levels of inbreeding. The project also indicated that the population studied had undergone a population expansion that seems to have coincided with the onset of the last ice age and is likely attributable to changes in climate.
Policy review of government regulation no. 55 of 2022 regarding regulations adjustment of income tax in the micro small medium enterprises (MSMEs)

This study aims to analyze GR No. 55 of 2022 with regulations that have an impact on previous regulations. The analysis technique used is qualitative with several approaches. The qualitative descriptive approach analysis technique analyzes the comparison of GR No. 55 of 2022 and the Miles and Hubermen approach analysis technique is used in the policy study of GR No. 55 of 2022. Data collection techniques by collaborating literature study techniques with in-depth interviews with academic and practitioner informants. The main findings of the study identified that a significant change in GR No. 55 of 2022 is the regulation of benefit-in-kind from non-taxable to taxable income. The determination of the value of benefit-in-kind can create room for disputes due to differences in perceptions arising from the valuation of benefit-in-kind based on the market price. This potential dispute becomes a reference for further regulation by the tax authority. The results of this study contribute to MSME taxpayers in fulfilling GR No. 55 of 2022 as an application of tax liability compliance.
The Impact of Bacterial Co-Infection on Hospitalized Children with Human Rhinovirus and Human Metapneumovirus Infections: A Retrospective Analytical Cross-Sectional Study

Background: Human rhinovirus (HRV) and human metapneumovirus (hMPV) are common viral causes of pediatric respiratory tract infections. Bacterial co-infections frequently complicate HRV and hMPV illnesses in children, but the interactions between viral and bacterial pathogens and their impacts on disease severity are not well understood. Objectives: The present research aimed to analyze and compare the clinical features of HRV and hMPV mono-infections in hospitalized children and to assess the impact of bacterial co-infection on the disease severity of HRV and hMPV infections. Methods: The present retrospective analytical cross-sectional study was conducted to compare the clinical features between HRV and hMPV mono-infections and HRV and hMPV with bacterial co-infections in hospitalized children aged 14 years or younger. Results: Between January and December 2022, we investigated 1,978 children hospitalized with HRV infection, of which 1,529 had HRV mono-infection and 1,117 hospitalized with hMPV infection, among whom 910 had hMPV mono-infection. Compared to HRV, hMPV mono-infection exhibited more pronounced symptoms of fever, cough, and rales in most age groups, while HRV showed more wheezing. Except in patients ≥ 6 years old, hMPV was more associated with pneumonia and longer hospitalizations. In contrast to HRV mono-infections, children with bacterial co-infections had a higher proportion of coughs (P < 0.001), pneumonia (P < 0.001), pediatric intensive care unit (PICU) admissions (P < 0.001), and longer hospitalizations (P = 0.003). Demographic characteristics, clinical presentation, diagnosis, and treatments showed no significant differences between patients with hMPV mono-infection and co-infection. Conclusions: Among hospitalized children, hMPV mono-infection resulted in more severe respiratory illnesses compared to HRV mono-infection. Bacterial co-infections exacerbated disease severity in HRV infections.
The responses of surface albedo to climatic changes in Xilin Gol grassland

This study assessed the reliability of Moderate Resolution Imaging Spectroradiometer(MODIS)-derived land surface albedo products for Xilin Gol grassland,illustrated the seasonal cycles and inter-annual variations of land surface albedo in Xilin Gol grassland,and analyzed correlations between surface albedo variations and climatic changes.The results show MODIS-derived dataset is able to capture seasonal cycle and inter-annual variations of surface albedo,though there is a difference between the MODIS-derived albedo and ground instrumental measurements.The MODIS-derived dataset illustrates that the seasonal cycle patterns of surface albedo vary with spectrum.For the visible band surface albedo,the seasonal cycle presents a "V"-shaped variation with the bottom in the first ten days of August.For the near-infrared band surface albedo,the seasonal cycle is "U"-shaped with the bottom in the period from June to September.However,both visible band surface albedo and near-infrared band surface albedo had consistent inter-annual variations.Moreover,the inter-annual variations of surface albedo were partly attributed to climatic variations.The effects of temperature were significant in the early(April to May) and late(September to November) growth season.The correlation coefficients between temperature and surface albedo were-0.67 and 0.63 in the early and late growth season,respectively.The effects of precipitation were significant through out the growth season.The correlation coefficients between precipitation and surface albedo ranged from-0.54 to-0.76. It is worthy noting that the effects of precipitation were usually lagged by 2-3 months.
The Design of Postgresql’s Security Protection Scheme

Postgresql is a widely used open source database, but it pays more attention to its general functions and performance, and the data security protection measures are seriously insufficient. Aiming at the problems of database security protection such as authentication password leakage and malicious copy of data, this paper studies postgresql database security protection mechanism and the data encryption, including database security protection model, authentication password leakage protection mechanism and underlying data malicious copy protection mechanism. Postgresql’s security protection scheme designed in this paper can break through the key problems such as abnormal data identification in high confusion mode, homomorphic migration of data operation and performance balance, and focus on solving two sensitive data leakage hidden dangers, such as fake login and copy & restore datas, so as to provide security for data storage.
Single-Doppler Radar Analysis of a Mesocyclone in the Taiwan Strait

In this study,the kinematic and precipitation structures of a mesocyclone associated with a hook echo were analyzed using single Doppler radar data.The mesocyclone was embedded in a mesoscale convective rainband near northern Taiwan coastline on 10 September 2004.The synoptic environment was characterized by a moderate convective available potential energy(CAPE) and a moderate ambient vertical shear from surface to 5 km.In addition,a pronounced low-level mesoscale shear/convergence zone,which resulted from the interaction of two tropical depressions,was also identified in the northwest coast of Taiwan,providing a favorable dynamic condition for the development of the mesocyclone. Analyzing single Doppler dipole signature shows that this mesocyclone formed initially at low levels, then deepened and strengthened rapidly into mature stage with the vertical depth exceeding 8 km.The diameter of the mesocyclone decreased with the height at the time of vortexgenesis,and then evolved into columnar structure accompanied with the broader diameter in middle layer.The mesocyclone lasted for about 2 h.The Ground-Based Velocity Track Display(GBVTD) method was applied to retrieve the axisymmetric circulation of the mesocyclone.The GBVTD-derived primary circulation showed the radius of maximum wind(RMW) of the mesocyclone was about 5-6 km and varied from inward tilting to outward tilting with time.The axisymmetric radial wind field was initially characterized by a low-level inflow inside the RMW and outflow outside the RMW,respectively.The strongest reflectivity was associated with a stronger updraft near the RMW,and a weak downdraft was located at the center of the mesocyclone. Subsequently the downdraft and reflectivity near the mesocyclone center strengthened obviously,accompanied with the low-level outflow,strong updraft as well as high reflectivity extending outside the RMW.The relative tangential wind initially exhibited a wavenumber 1 asymmetric structure with the maximum wind region at the left portion of the meso cyclone and shifted counterclockwise with height.The axisymmetric tangential wind strengthened and reached its maximum intensity with a value about 20 m s~(-1) at z=1 km. After that the axisymmetric tangential wind decreased rapidly,meanwhile the wave-1 asymmetric structure redeveloped with the maximum wind at the left-front of motion.In summary,the evolution and structure of the mesocyclone is similar to that observed within a non-supercell mesocyclone.It is worth to mention that the axisymmetric circulation characteristics of the mesocyclone at its mature stage are very similar to those observed in a mature typhoon.However,there are significant differences,i.e.,the size is much smaller,the lifetime is much shorter,and the downdraft in the center is produced by precipitation instead of compensating subsidence.
