Authors: Khraibet Maysoon Sami , Atiyah Nadia Ridha , Aziez Tuorkia Sheerza 
Published: January 2025

Background: Endometriosis is characterized by the presence of endometrial tissue outside the uterus There are no definitive signs or symptoms associated with endometriosis, and its presentation can be different based on the affected areas. It is a prevalent cause of various degree of infertility among younger women. The management approach of endometriosis may involve both medical and surgical therapy. Laparoscopic procedures have shown promising results in enhancing fertility prospects for young women suffering from endometriosis. Methods: This study included women diagnosed with endometriosis after experiencing infertility. A comprehensive history was taken, focusing on symptom duration, any additional co-morbidities, and the length of infertility. All patients underwent diagnostic laparoscopy. Based on the site and severity of the endometriosis, procedures such as adhesiolysis, excision, and ablation of endometrial lesions were performed. Patients were monitored, and instances of successful pregnancies (both spontaneous and those resulting from assisted reproductive techniques) were documented. Results: Among the 100 cases studied, endometriosis was identified in 12 patients (11.5%). The most frequently affected age group was 26-30 years (47.83%). A total of 9 patients (78.26%) had primary infertility, while the remaining 5 patients (21.74%) experienced secondary infertility. The ovaries were the most commonly affected site, involved in all cases. Surgical interventions performed included cystectomy (30.43%), endometrioma drainage and fulguration (13.04%), and adhesiolysis (34.78%). Of the 9 patients who achieved successful ovulation following laparoscopic surgery, 6 (66.66%) went on to complete their pregnancies successfully. Conclusions: Laparoscopic procedures for infertility provide both diagnostic and therapeutic benefits and yield favorable outcomes concerning successful pregnancies.
Highlights:

Endometriosis impacts fertility: Laparoscopy is crucial for diagnosis and treatment.
Surgical interventions: Enhance fertility by addressing endometrial lesions.
Study focus: Infertile women, ages 18-40, with laparoscopy-confirmed endometriosis.

Generative artificial intelligence causes displacement for white-collar workers but reduces regional opportunity disparities
Authors: Liu Lun , Hu Jiayin , Wang Anqi , Weng Zongyuan 
Published: January 2025

Abstract

Recent developments of generative artificial intelligence (GenAI) have reignited discussions about technological unemployment, yet empirical evidence remains scarce. Using a comprehensive dataset of over one million online job postings from China spanning 2018 to 2024, this study provides a timely assessment of GenAI’s impact on local and regional labor markets following the surge of GenAI tools in late 2022. Our analysis reveals a nontrivial job displacement effect of GenAI in the short and medium run, disproportionately affecting entry-level, high-wage positions and highly-educated workers. Notably, this displacement effect is more pronounced in larger, more economically developed cities, suggesting a reduction in job opportunity disparities across regions in era of GenAI. We also find that lower labor costs and higher occupation diversity increase the resilience of local labor markets to the disruptive effects of GenAI. These findings offer crucial insights for policymakers to mitigate the adverse consequences of GenAI while harnessing its potential for positive societal transformation.
Crystal Phase Reconstruction of Bi-(N-C)/Bi(OH)3-Bi2O3 for Selective Cleavage of Lignin Cꞵ-O-4 Bond via Fluidized Electrocatalysis

Published: January 2025

Abstract

Developing efficient systems for directional lignin depolymerization via cleaving the aryl ether bonds to produce high-value-added chemicals is intriguing but remains challenging. Herein, we report a crystal phase reconstruction strategy for the synthesis of heterogeneous Bi-(Et3N)0.3 catalyst with rich defect sites and high-valence Bi species, which exhibits promising performance towards the fluidized electrocatalytic hydrogenation (FECH) of lignin-derived 2-phenoxy-1-phenylethanol with full conversion and up to 60.7% yield of phenol formation. Experimental and theoretical results confirm that the high-valence Bi species is beneficial in promoting the rapid activation of the protons, while the rich-defect sites derived from the crystal phase reconstruction between Bi-O and Bi-N-C coordination optimize the adsorption-activation of oxygen-containing intermediates. Moreover, by manipulating the variation of current density, the dissociation efficiency of protons and the enrichment degree of the electron-rich ([PW10VIW2VO40]5−) groups of the phosphotungstic acid (HPW) electrolyte were modulated, enabling the controllable switching of the phenol generation pathway. This study elucidates that the synergy between defect sites and high-valence Bi metals could advance the rational design of efficient electrocatalytic systems for the directional and efficient cleavage of lignin Cꞵ-O-4 bonds for high-value-added chemicals.

Published: January 2025

Abstract

Background: Hematologic abnormality, especially anemia, and changes in total and differential blood counts are mostly observed with this condition. Advanced CKD patients undergo hemodialysis as a standard treatment, and consequently, the parameters go along with these patients. Acquiring the relevant changes will help in improving patient management and complications arising from CKD.
Objective: To evaluate the change in total and differential blood counts in adult CKD patients before and after hemodialysis, especially as it concerns levels of hemoglobin, hematocrit, red blood cells, white blood cells, platelets, and differential count (neutrophils, lymphocytes, monocytes, eosinophils).
Methods: A prospective observational study was conducted at Kisii Teaching and Referral Hospital, Kenya, on 120 adult chronic kidney disease patients on hemodialysis. Blood samples were taken before the start of the dialysis session (pre-hemodialysis) and taken within 30 minutes after the dialysis session (post-hemodialysis). Automated hematology analyzer performed all necessary hematological analysis that included total blood count and differential blood count. The data were analyzed using SPSS version 26. Pre- and post-hemodialysis values were compared with t tests for paired samples or Wilcoxon signed-rank tests.
Results: The mean hemoglobin concentration increased significantly from a baseline value of 8.4 ± 1.9 g/dL pre-hemodialysis to a post-hemodialysis concentration of 10.1 ± 2.1 g/dL (p < 0.001). Hematocrit and red blood cell counts also increased considerably (p < 0.01). White blood cell counts dropped significantly from 8.5 ± 3.4 × 10³ cells/μL pre-hemodialysis to 7.3 ± 2.8 × 10³ cells/μL post-hemodialysis (p = 0.004). The platelet count also fell from 270 ± 82 × 10³ cells/μL pre-hemodialysis to 248 ± 75 × 10³ cells/μL post-hemodialysis (p = 0.03). Neutrophil percent decreased while lymphocyte percent increased significantly post-hemodialysis (p = 0.01 and p = 0.02 respectively).
Conclusion: Hemodialysis is shown to significantly improve hemoglobin, hematocrit, and red blood cell counts in adult patients who have chronic kidney disease. However, hemodialysis reduces white blood cell and platelet counts in adult chronic kidney disease patients. These modifications in hematology may have been of benefits of the clearance of uremic toxins and the reduced inflammation during dialysis. Certain of these modifications, like anemia or changes in platelets, persist beyond the process, establishing the need for further management of hematological manifestations in chronic kidney disease patients. Long-term studies are also encouraged to cover the extent of the effects of dialysis on hematological and immune functions among chronic kidney disease patients.
Advances in Iron Deficiency Management in Chronic Kidney Disease: Insights into Pathophysiology, Diagnosis, and Therapeutic Approaches
Authors: Ogolla Collince Odiwuor , Karani Lucy W. , Musyoki Stanslaus , Maruti Phidelis 
Published: January 2025

Abstract

Background: Iron deficiency is very common and is clinically significant in patients with chronic kidney disease (CKD). It contributes to anemia and adversely affects outcomes in these patients, including quality of life, and survival. For all the advancements in our understanding of iron metabolism, the optimal methods for treating deficiency in patients with CKD continue to be an area of active research.
Objective: The focus of this review is to describe the advances in the pathophysiology, diagnosis, and management of iron deficiency in CKD, emphasizing its biomarker value and the efficacy of oral versus intravenous (IV) iron supplementation.
Methods: One hundred twenty patients with chronic kidney disease (stage 3 to 5) suffering from anemia due to iron deficiency were included in this prospective, observational study. They were assigned to either Group A (mild to moderate iron deficiency anemia [IDA], n=60) or Group B (severe IDA, n=60), according to the severity of iron deficiency. Group A received oral iron supplementation, whereas Group B received IV iron therapy. Various parameters on lab tests were measured (initial and after the treatment duration of 8 weeks) for assessment: serum ferritin, transferrin saturation (TSAT), soluble transferrin receptor (sTfR), and serum hepcidin levels. The primary outcome was change in hemoglobin levels, whereas change in iron biomarkers counted as secondary outcomes.
Results: The efficacy of IV iron therapy was superior to oral iron supplementation in increasing hemoglobin concentrations and iron parameters (p<0.05). In Group B, the mean increase in hemoglobin concentration was 2.3 g/dL, along with impressive data regarding serum ferritin, TSAT, and sTfR. Elevation in hepcidin levels was significant in severe iron deficiency, indicating that less iron was available for erythropoiesis. The comparison of sTfR as a diagnostic marker showed it to be a better indicator than the traditional markers, such as ferritin, under inflammatory conditions.
Conclusion: IV iron supplementation is better than oral iron for treating severe iron deficiency in patients with CKD, leading to better clinical outcomes. New biomarkers, such as sTfR, are much better in evaluating iron status in CKD patients than before, especially in those with concurrent inflammation. All these weighs heavily toward individualized management of the disease.

Published: January 2025

Abstract

This study examines the influence of effort, growth mindset, and motivation on mathematics performance, comparing the effectiveness of traditional and machine learning regression models. Using secondary data from 4,552 students, five models—multiple regression, Random Forest, Gradient Boosting, XGBoost, and LightGBM—were evaluated for predictive accuracy and feature importance. The results demonstrate that machine learning models, particularly XGBoost, significantly outperform traditional regression, with XGBoost achieving the lowest Mean Squared Error (MSE = 7186.49) and the highest R-squared (0.1571). Effort emerged as the strongest predictor, followed by growth mindset, while motivation had a smaller but notable influence. These findings reinforce the applicability of Self-Regulation Theory and Growth Mindset Theory, highlighting the potential of machine learning to enhance educational research. Practical implications emphasize the importance of fostering effort and growth mindset through targeted interventions and leveraging predictive analytics for data-driven decision-making in education.
Adoption of the budget by competence in Brazil based on comparative experiences in the USA, Canada, United Kingdom, Australia, and New Zealand
Authors: Gonçalves Andrew Pereira , Nascimento Roberto Sérgio do , Viotto Ricardo 
Published: January 2025

Purpose: To analyze the feasibility of adopting competency budgeting in Brazil.
Methodology: Qualitative, exploratory, bibliographic, documental, and content analysis nature, with the cataloguing of the material based on environmental attributes (political commitment, human capital, long-term sustainability, and macroeconomic policy) and technical attributes (depreciation and valuation of assets, capital expenditure, symmetry between reports, recognition of benefits and accountability). The work is comparative in nature based on the practices adopted in the USA, Canada, United Kingdom, Australia, and New Zealand.
Results: The examinations of environmental attributes in comparison with technical attributes were more homogeneous in reference to the countries analysed. It was identified that the technical attributes were the ones that were more casuistic, aiming to meet the specific situations of the participating countries. In Brazil, if the reform were implemented, the study pointed to attributes related to macroeconomic (environmental) policy and accountability (technical) as being the most favorable.
Contributions of the Study: It was identified that the most advanced experiences on accrual budgeting come from countries of Anglo-Saxon origin, whose accounting systems are convergent with those used by companies. In this sense, it is hoped that the work can contribute to the broadening of the discussion of the systematics, in view of the indication of environmental and technical attributes considered to facilitate and/or hinder the process.

Published: January 2025

Background
Dental caries, a multifactorial tooth-related disease, is significantly influenced by microorganisms, like Streptococcus mutans. This bacterium causes dental caries and destruction by forming a biofilm on the tooth surface. This study aimed to prepare Hypericum perforatum nanoemulsion and evaluate its anti-biofilm effects against Streptococcus mutans bacteria.

Methods
Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and Minimum Biofilm Inhibitory Concentration (MBIC) were used to assess the antimicrobial and anti-biofilm properties of the nanoemulsion.

Results
The results showed that the Hypericum perforatum nanoemulsion had less MIC, MBC, and MBIC than the free oil form (p=0.03, p=0.03, and p=0.02, respectively). The results also showed that the Hypericum perforatum nanoemulsion had less MIC and MBC than amikacin as a positive group (p=0.04 and p=0.04, respectively); however, the MBIC of nanoemulsion and amikacin was similar (p=0.07).

Conclusion
The studied nanoemulsion can be used as a potent and new material for preventing dental caries.
