 Ozonized Water as an Adjuvant in Hand Hygiene: Analysis of the Impact on Microbial Reduction Infections are among the most common adverse events affecting patients in hospital settings, and hand hygiene is a primary measure for disease prevention. This study analyzed the impact of using ozonated water as an adjuvant in reducing microorganisms present on the hands of surgical teams before pediatric cardiovascular operations, and on the hands of nurses working in the Intensive Care Unit (ICU). Over one year, a quantitative microbiological analysis was conducted on 224 hand surface samples from 10 ICU professionals and 5 surgical center professionals, which constituted the study material. Samples were collected at two distinct times: before and after hand hygiene and rinsing with either water without ozone or ozonated water.  There was a 100% reduction in the number of Colony-Forming Units (CFU) in surgical center samples after rinsing with ozonated water, with p=0.0029 for the ...

 Congenital Infections: The Reality of a Municipality in Southwestern Goiás The present work aimed to identify cases of congenital infections up to the first two years of life in a municipality in the southwest of Goiás, considering that they represent an important public health problem, given the indicators of neonatal morbidity and mortality. This is an epidemiological, descriptive, analytical study, investigating cases of congenital infections by consulting the medical records of children treated at a specialty outpatient clinic in the city. A Chi-Square test of independence was performed to investigate the association between diagnosed diseases and the variables pregnancy history, period of diagnosis and maternal age. The results indicate that women with a maternal age between 20 and 30 years are 4.19 times more likely (95% CI: 1.14 - 15.45) to be diagnosed with syphilis compared to those with a maternal age younger than 20 years. Therefore, maternal age is considered a factor ...

 Research Trends in Nursing and Health Care in Low-Resource Countries: Kenya's Example The delivery of healthcare and nursing practice are severely hampered in low- resource nations like Kenya by inadequate infrastructure, a lack of workers, and a lack of funding for research. A growing corpus of research addressing creative strategies and context specific solutions has emerged in spite of these obstacles. In Kenya, research in nursing and healthcare has expanded dramatically, tackling important health issues like infectious diseases, non- communicable diseases, maternal and child health, and workforce issues. Increased scholarly participation, governmental programs, and global partnerships are all responsible for this progress. But persistent obstacles such as a lack of mentorship, inadequate infrastructure, and financial limitations keep getting in the way of new developments. To speed up progress, it is crucial to increase funding for research, improve mentorship programs, use d...

  Defibrillation Vector Change in CPR A Systematic Review Cardiopulmonary resuscitation (CPR) and early defibrillation are essential for managing cardiac arrest. Defibrillation, which interrupts chaotic myocardial electrical activity, has traditionally been performed using an automated external defibrillator (AED) with pads in the anterolateral position. However, in cases of refractory ventricular fibrillation (VF), the effectiveness of this technique may decrease, leading to the exploration of alternatives such as defibrillation vector change. This strategy aims to improve shock efficacy by redistributing the electric field and promoting synchronized myocardial depolarization. This study aims to analyze the scientific evidence on the impact of defibrillation vector change on rhythm conversion, return of spontaneous circulation (ROSC), and survival in patients with cardiac arrest. A systematic review with a meta-analysis of studies published between 2020 and 2025 was conducted, inc...

 Petrophysics and Well Log Correlation of “FTP” Field Offshore Niger Delta One challenging thing about doing formation evaluation studies in clastic formation like the Niger Delta is accurately identifying and mapping the reservoir sands and their edges. This is also true when studying the offshore Niger Delta. The database comprised borehole logs from four wells. Gamma ray logs were used to map the lithology while thye hydrocarbon bearing reservoirs were identified with a mix of gamma ray and resistivity logs. Well-logged correlation was carried out using similarity in log signatures. Schlumberger software (PETRELTTM) was used for interpretation. The computation of petrophysical parameters such as net-to-gross volume, volume of shale, porosity, permeability, and hydrocarbon saturation was done using standard equations. The general lithology in the area is an alternation of sands and shales. Three reservoirs designated as R1, R2, and R3 extend across all the wells. Reservoir R1 is ...

 Perforation of Casing Strings in Oil and Gas Wells with a Polymer Solution Jet: Scientific and Practical Aspects The hydrodynamic behavior of water–polyethylene oxide (PEO) solutions under model flow conditions in hydroperforator jet-forming nozzles was investigated. Experimental results confirmed that, in the nozzle inlet region, PEO macromolecular coils can transition into a highly extended conformation. The ratio of the measured birefringence to its theoretical maximum reached 0.33, corresponding to approximately 60% uncoiling of macromolecular chains. The energy potential of high-velocity jets formed from water–PEO solutions was studied at various polymer concentrations and nozzle discssharge pressures. Evaluation was conducted based on the penetration depth of the jet into a model casing string of an oil and gas well, the cement sheath, and the surrounding rock formation. Additional assessment was performed by measuring the impact force of the jet on a metal target mounted on...

 Agroindustrial Waste: Importance and Applications in the Production of Microbial Enzymes The growing environmental concerns have intensified interest in renewable sources, promoting the use of agro-industrial residues as alternative substrates for the production of materials, chemicals, and bioenergy. Among these residues, cheese whey stands out due to its high content of lactose, proteins, and minerals, and is widely used in microbial fermentations to produce industrially relevant compounds such as enzymes. Likewise, lignocellulosic wastes like sugarcane bagasse have proven effective as carbon sources for cellulase production, while corn steep liquor has been employed as an inexpensive nitrogen source. Studies involving Bacillus licheniformis SMIA-2 have demonstrated its potential to produce enzymes such as proteases, avicelase, and carboxymethyl cellulase (CMCase) using agro-industrial residues, including passion fruit peel flour, cheese whey, and sugarcane bagasse supplemented ...

 The Role of Breeding in Increasing the Adaptation of Crops to Climate Change in Conditions of Tajikistan The article presents scientific results on the creation of new promising varieties of a number of agricultural crops, which are currently widely cultivated in the lands of farms in Tajikistan. Based on the analysis of the work of local and foreign breeders, it was found that in the future, such breeding methods as remote interspecific hybridization, mutagenesis and introduction will play an important role in the adaptation of agricultural crops to climate change. Due to the fact that global climate change causes an increase in air temperature, an increase in the level of soil salinity, a lack of moisture in the soil, an increase in the number of pests and plant diseases, etc., it is necessary to strengthen breeding and genetic research in the future. In this regard, the goal of our long-term breeding work was to obtain new intensive varieties of such important agricultural crop...

 Denied by Design: Navigating the Access to Workers’ Compensation Care in Chicago Workers’ compensation (WC) was introduced as a no-fault system to provide injured workers with timely access to medical treatment and compensation for lost wages. When the treating physicians submit a care request to the third party insurer, these requests are often subjected to a utilization review process. Utilization Review (UR) is the process of comparing an injured worker’s case to evidence-based clinical guidelines that outline national standards for a patient with similar symptoms as the one being reviewed. UR often results in a delay or denial of treatment and access to care. Analyzing these disparities can help improve patients' access to appropriate and necessary medical care. A retrospective case series was utilized to analyze existing treatment plans of multiple patients subjected to the UR process. Consent was obtained from an orthopedic private practice located in the Greater Chicago Are...
