The study examined crude oil exploration activities and particulate matter pollutants concentration in selected Rivers East and Rivers South-East communities, Rivers State. The study adopted the completely randomized block design (CRBD). Ambient air quality readings were taken in-situ in four (4) stations (two each from each of the communities) using the Aero Qual 500 Series (Gas Monitor), GT 321 Particulate Metre, Automated Global Position System (GPS), and Extech Meteorology Metre, While mean and clustered column chart was used to analyze the data. The study revealed the concentrations of 694 ppm and 613 ppm for CO2 in Bodo and Igwuruta communities respectively which were higher than the WHO daily approved limit of 462 ppm. The study further revealed that the higher concentration of particulate matter pollutants (PMPs) like (NO2 = 0.098 μg/m3, O3 = 0.04 μg/m3, So2 = 0.00 μg/m3, H2S = 0.01 μg/m3, CH4 =0 μg/m3, CO = 0.5 μg/m3, NH3 =0.3 μg/m3, Pm 2.5 = 0.022 μg/m3, Pm 10 = 0.018 μg/m3, temperature = 34.6 oC) obtained at the Bodo artisanal refining sites and that obtained at the Igwuruts flow station were all still within the WHO daily approved limits for the specific PMPs. Also, the excessive concentration of CO2 accentuates the presence of soot that exacerbates the discolouration of vegetation as well as poor air quality, residents’ high susceptibility to skin diseases, cancer and respiratory ailments, intense heat, respiratory complications like cough, carthar, etc. The study recommended amongst others that more trees should be planted to absorb the excess CO2 that accentuates the buildup of soot that damage the built environment; destroy car windshield, roof surfaces, house floors and windows and also, causing health risk of rashes, aging, asthma, bronchitis on the residents around the environs of the Agbada/Igwuruta flow station and Bodo artisanal refining site.

Background: Children's headaches are not well understood, and diagnosis can be difficult. Children who get frequent headaches are frequently badly impacted. The relationship between lifestyle factors including food, exercise, and sleep and the occurrence of headaches, particularly migraines, has been investigated mostly in adults, leading to changes in lifestyle as a conventional treatment in addition to medical therapy. Objective: To find out clinical profile of children with recurrent headache. Materials and Methods: This is a cross sectional study was conducted Centre for Neurodevelopment and Autism in Children (Pediatric Neurology OPD), Dept. of Pediatrics of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during January 2022 to June 2022. Total of 100 children attending with recurrent headache were taken consecutively over a period of six months for this study. Patient with recurrent headache were classified (diagnosed) based on clinical presentation (according to International Headache Society diagnostic criteria). Results: The majority of patients (54%) suffered migraines without aura, and 48% had severe headaches. 70% of patients exhibited sensitivity to bright light during a headache episode, 80% had sensitivity to noise, 85% had no headaches while playing TV video games, and 66% had a history of headaches caused by sun exposure. Conclusion: Males dominated in the pre-pubertal age range, whereas girls dominated after puberty. The most prevalent RHA diagnosis was migraine without an aura. Headache triggers or precipitating factors were also compared to previous research.

Background: Chronic obstructive pulmonary disease is one of the most common non-communicable illnesses, having the potential to be fatal, it is now the third leading cause of death worldwide. Objectives: The aim of our study was to estimate the prevalence of COPD, its associated risk factors, causes and management in Saudi Arabia. Methods: For article selection, the PubMed database and EBSCO Information Services were used. All relevant articles relevant with our topic and other articles were used in our review. Other articles that were not related to this field were excluded. The data was extracted in a specific format that was reviewed by the group members. Conclusion: In Saudi Arabia, the prevalence estimated of COPD is relatively high, moreover it increases by time. High prevalence of smoking and increased age was reported to be the most common effective risk factors of COPD in Saudi population. COPD is now considered a preventable and potentially treatable disease if detected in the early stages. Avoidance of exposure to harmful particles, mainly smoking, can prevent progression to a clinically significant stage of the disease.

This study examines the impact of oil price volatility on economic growth in Nigeria over the period 1990–2024. Real exchange rate, nominal exchange rate, exchange rate volatility and inflation rate as a stand in for exchange rate volatility while oil export revenue serves as the dependent variable. Data were sourced from the World Banks World Development Indicator (WDI), and Central Bank of Nigeria) statistical Bulletin 2024. The empirical result revealed that exchange rate molality had a long-run relationship with oil export revenue in the long-run according to the bound test. Further findings showed that both the real exchange rate and nominal exchange rate exert a negative but statistically significant effect on oil export revenue, while exchange rate volatility and inflation rate exhibit a positive but statistically insignificant relationship with oil export revenue in the long run. Based on these findings, the study concludes that exchange rate volatility plays a significant role in influencing oil export revenue in Nigeria. It was recommended amongst other that the Central Bank of Nigeria should prioritize policies that promote exchange rate stability. This can be achieved through managed float regimes, adequate foreign reserve management, and timely interventions in the foreign exchange market to reduce excessive depreciation of the naira.

Background: Traditional mono-focal intraocular lenses (IOLs) have been commonly used in cataract surgery but have limited intermediate vision. These lenses are designed to achieve improved visual outcomes and optical quality without the drawbacks associated with multifocal lenses. The present study compares visual outcomes, optical quality, and patient satisfaction for Monofocal versus Monofocal-Plus IOLs. Methods: This postoperative observational study was carried out at Department of Ophthalmology, Dr. Sirajul Islam Medical College and Hospital and Bangladesh Eye Hospital, Dhaka, Bangladesh, from July 2022 to June 2023, including 40 cataract surgery patients. Patients were divided in Monofocal IOL (n=20) & Monofocal-Plus IOL (n=20) groups. Preoperative 1-month and 3-month follow-up assessments of visual acuity (LogMAR), contrast sensitivity (logCS), higher-order aberrations (HOA), and patient satisfaction scores were performed. SPSS version 26 was used to analyze data, with a p<0.05 significance level. Results: Uncorrected visual acuity was significantly better 3 months post-op with mono-focal-plus IOL at 3 months (p=0.008), photopic contrast sensitivity (p=0.04), and spherical aberration (p=0.00). There was a trend toward improvement in best-corrected visual acuity (p=0.08). Monofocal-Plus IOL patients reported significantly lower glare (p=0.01) and halos (p=0.01) and better night vision quality scores (p=0.005). The requirement for more spectacles was less in the Monofocal-Plus group (15.0% vs. 35.5%), but not significant (p=0.14). Conclusion: Compared to Monofocal IOLs, Monofocal-Plus IOLs provide better visual performance, optical quality, and higher patient satisfaction. These findings support their adoption as an IOL of choice in cataract surgery.

The administration of iodinated contrast media (ICM) is indispensable for modern diagnostic and interventional procedures. However, the subsequent development of acute kidney injury (AKI) represents a significant clinical challenge, associated with increased morbidity, mortality, and healthcare expenditure. Historically termed contrast-induced nephropathy (CIN), the understanding of this condition has evolved, leading to the more precise term contrast-associated AKI (CA-AKI) to reflect a temporal association rather than assumed causality. The pathophysiology is multifactorial, involving direct tubular cytotoxicity, renal vasoconstriction leading to medullary hypoxia, and oxidative stress. While the risk is low in the general population, it is markedly elevated in patients with pre-existing chronic kidney disease (CKD), diabetes mellitus, heart failure, and in the context of intra-arterial procedures with high contrast volumes. The prevention of CA-AKI has traditionally been managed in departmental silos, an approach that is often fragmented and unreliable. This review proposes a comprehensive, multidisciplinary framework that integrates the expertise of four key pillars: Radiology, Pharmacy, Anesthesia, and Public Health. Effective prevention begins with a shared foundation of robust risk stratification, leveraging quantitative scoring systems and automated electronic health record (EHR) alerts. The Pharmacy pillar focuses on evidence-based pharmacological and medication management, including standardized hydration protocols, controversial adjunctive therapies like N-acetylcysteine and statins, and a critical "nephrotoxic hold" on high-risk medications. The Radiology pillar centers on procedural optimization through the selection of appropriate contrast agents, strict adherence to the principle of dose minimization guided by dose-to-eGFR ratios, and the use of advanced technologies like automated injectors and ultra-low contrast techniques. The Anesthesia pillar provides intraprocedural hemodynamic stewardship for high-risk patients, maintaining renal perfusion through goal-directed fluid therapy and judicious use of vasopressors. Finally, the Public Health pillar provides the system-level architecture for success, designing and implementing hospital-wide "prevention bundles," fostering interdepartmental communication, promoting patient education, and driving continuous quality improvement through audit and feedback. By synergizing these distinct but complementary roles, healthcare systems can transition from a reactive to a proactive and reliable model of care, significantly reducing the clinical and economic burden of CA-AKI.

Introduction: The concept of "Balanced Regional Development" has been formally adopted as a primary goal of Economic Planning on a Global Scale throughout history and into the future. Its intention is to minimize spatial disparities between geographic regions, as well as provide access to opportunity and resources equally across the country. North Bengal’s development strategy must take a thoughtful, integrated, multi-dimensional approach that includes: improvements to physical infrastructure; initiatives to encourage new industry sectors; the expansion of human capital; and the development of institutional structures that promote participatory planning and equitable access to resources. Objective of the Study: The study has tried to identify the causes, which differ between the North Bengal and the South Bengal, and to focus primarily on ways to eliminate these disparities and develop in a unified plan for regional equity. Methodology: The Study is a combination of the analytical method to study regional differences, and the policy method to develop strategies for the equitable development of all regions. It uses a combination of both the theoretical perspective to understand and the empirical perspective to collect the data. Result and Discussion: Identification of gaps of development between North Bengal and South Bengal with its reasons and nature has been sought first and then shown. Conclusion: For North Bengal to succeed, it too needs a well-planned, long-term, and integrated approach to address all aspects of its development, such as making its economy more varied, building better roads and schools, improving access to quality healthcare, developing sustainable agricultural practices, and strengthening local institutions.

This research examines Artificial Intelligence (AI) and Machine Learning (ML) applications in financial risk assessment and investment strategies for mergers and acquisitions (M&A). A comprehensive analysis of over 20,000 global deals from 2013-2023 shows that integrating Ai to predict M&As could reduce transaction failure rates and increase valuation accuracy. After testing multiple algorithms, the XGBoost classifier performed best for merger success with a recall of 60% and precision of 62% on historical data from the Institute of Mergers, Acquisitions and Alliances. The main contribution of this work is a new integrated framework that combines AI-driven quantitative analysis with human expert judgment, addressing the fundamental limitations of both purely algorithmic and solely human-driven approaches to M&A evaluation. This outperforms existing benchmarks in the literature and is a big step forward in predictability. The results also suggest explainable AI architectures, human-machine collaboration protocols and multidisciplinary training for professionals to ensure accountability, transparency and operational efficiency. The research concludes that AI in M&A is not just about the technology but about how it’s integrated with human judgment, ethical governance and context specific communication frameworks

The primary motivation for individuals with deep-bite malocclusion seeking orthodontic treatment is the improvement of aesthetics, occlusion, and functions. Deep bites can be treated by the intrusion of anterior teeth and the extrusion of the posterior teeth, or both, according to the exposure of the incisors in the smile. In this case report, we present the treatment of a female patient with a deep-bite malocclusion. This paper describes the clinical and radiographic changes with orthodontic treatment using Invisalign clear aligners and their effectiveness to normalize the overjet and overbite and enhance both aesthetics and functions.

Anterior open bite is a complex malocclusion that often requires comprehensive treatment due to its multifactorial etiology and high relapse potential. Conventional treatment options such as orthognathic surgery or extraction therapy may have limitations. Recent advancements in skeletal anchorage have introduced miniscrews as a minimally invasive and reliable alternative. This case report illustrates an 18-year-old female with sagittal skeletal Class II pattern, hyperdivergent facial type and class I molar and end-on Class II canine relationship, with an anterior open bite. The treatment plan consisted of using miniscrews placed bilaterally in the posterior maxilla to facilitate molar intrusion. A transpalatal arch was used to maintain transverse stability during the intrusion phase. The approach resulted in effective molar intrusion, closure of the open bite, and an improved facial profile.

In this study we have studied "Killing Motion of Static Cylindrically Symmetric Spacetimes in f(R) Gravity" by using algebraic and direct integration techniques. This study investigates the Killing motions of static cylindrically symmetric spacetimes with in framework of f(R) gravity, a generalization of Einstein’s General Relativity. We explore the existence of Killing vector fields to understand the symmetries and conserved quantities in such spacetimes. By analysing the modified field equations, we determine the constraints imposed by f(R) gravity on the geometry and dynamics of cylindrically symmetric spacetimes. These contribute to understanding the interplay between symmetry properties and gravitational theories beyond General Relativity. The results have implications for astrophysical and cosmological models influenced by alternative gravity theories. We discussed four cases and found that the dimension of Killing vector fields is either three, four or ten.

Snakebites are serious public health problem in many regions of the world, particularly in rural areas lacking medical facilities. Snake bite is a well-known occupational hazard amongst farmers, plantation workers, and other outdoor workers and results in much morbidity and mortality throughout the world. This occupational hazard is no more an issue restricted to a particular part of the world; it has become a global issue. Accurate statistics of the incidence of snakebite and its morbidity and mortality throughout the world is difficult to publish, however, it is certain to be higher than what is reported. This is because even today most of the victims initially approach traditional healers for treatment and many are not even registered in the hospital. Hence, registering such patients is an important goal if we have accurate statistics and reduce the morbidity and mortality due to snakebite. World Health Organization (WHO) has published guidelines for the clinical management of snakebites. In this article the author tries to throw light on the incidence and clinical features of snakebite and the management and treatment guidelines as per the WHO recommendation.

Enhancing aesthetics, occlusion and functions is a primary motivation for individuals with open-bite malocclusion seeking orthodontic treatment. Open-bite malocclusion, characterized by a lack of vertical overlap of the anterior teeth, can be effectively treated with a combined surgical and orthodontic approach. In this case report, we present the treatment of a male patient with an open-bite malocclusion and a skeletal class II. Initially, the patient underwent a presurgical phase where fixed orthodontic appliance was bonded to achieve well-aligned arches, then came the maxillary impaction to normalize the overjet and overbite and enhance both aesthetics and functions. Keywords: Skeletal Class II, Open-Bite Malocclusion, Orthodontic Treatment, orthognathic surgery, Maxillary Impaction.

Background: Urinary tract infection (UTI) is one of the most prevalent bacterial infections during pregnancy, associated with significant maternal and fetal morbidity if left untreated. The physiological changes of pregnancy, such as urinary stasis and altered urine composition, increase the risk of both symptomatic and asymptomatic UTIs. Early identification and management are therefore crucial. Aim of the study: To evaluate the incidence of urinary tract infections during pregnancy and assess the associated maternal and fetal outcomes in a tertiary care setting. Methods: This prospective study was conducted over two years in the Department of obstetrics and Gynecology, Rangpur Community Medical College Hospital, Rangpur, Bangladesh. A total of 220 pregnant women aged 18–40 years were enrolled, of whom 41 were diagnosed with UTI based on clinical presentation, urine microscopy, and culture sensitivity. Patients were classified as having symptomatic or asymptomatic UTI and were followed throughout pregnancy and postpartum for adverse outcomes. Statistical analysis was performed using SPSS version 26. Result: Among the 41 UTI-positive cases, the highest incidence (60.98%) was observed in women aged 18–25 years and in primigravida patients (56.10%). The majority (58.54%) of infections occurred during the second trimester. Asymptomatic UTI accounted for 65.25% of cases. The most common pathogen was Escherichia coli (36.59%), followed by Klebsiella (24.39%). Adverse maternal outcomes included anemia (26.83%), puerperal pyrexia (24.39%), and abortion (12.20%). Fetal complications included preterm birth (36.59%), fetal growth restriction (14.63%), and perinatal mortality (12.20%). Conclusion: UTI during pregnancy is a frequent and often silent infection, with significant implications for both maternal and fetal health. Routine screening and prompt treatment are essential, especially during the second trimester, to minimize complications such as preterm labor, intrauterine growth restriction, and perinatal mortality.

Retroperitoneal teratoma represents 1-11% of primary retroperitoneal tumors [1]. It is generally benign whether mature or immature. The treatment is surgical and the prognosis is excellent in the absence of complications. We report a case of mature retroperitoneal teratoma in an 8-year-old girl revealed by an isolated right paramedian abdominal mass. CT revealed a right suprarenal mass, fatty density with calcifications, without invasion of neighboring structures, measuring 124 mm in transverse diameter, 104 mm in anteroposterior diameter and 174 mm in height. Management consisted of complete excision of the tumor without incident.
