Background: Occupational bronchopulmonary diseases (OBPDs)—including pneumoconiosis, silicosis, and occupational COPD—remain a pressing public health issue, especially in regions with intensive mining, metallurgy, and construction industries. Caused by chronic inhalation of fibrogenic dusts, these conditions are often diagnosed at late stages, resulting in irreversible lung damage and diminished work capacity. Methods: A scoping review was performed using the Arksey and O’Malley framework, with methodological refinements from the Joanna Briggs Institute. Following PRISMA-ScR guidelines, we searched PubMed, Scopus, and gray literature for publications from 2014 to 2024. After screening 1761 records and full-text review, nine studies were included in the final synthesis, comprising two systematic reviews, two narrative literature reviews, and five observational studies. Results: Key risk factors identified included prolonged exposure to silica and coal dust, tobacco use, and genetic susceptibility. Diagnostic delays were attributed to the underuse of high-resolution CT and exhaled nitric oxide analysis. Several studies highlighted the diagnostic value of oxidative stress and inflammatory markers (e.g., IL-6, TNF-α). Nutritional rehabilitation and polyphenol-enriched herbal therapies were associated with improved respiratory function and quality of life. However, these strategies remain underutilized, particularly in low-resource settings. Conclusions: A coordinated, biomarker-driven approach integrating early diagnosis, dust exposure control, and tailored rehabilitation is urgently needed. Multidisciplinary models may reduce the clinical and socioeconomic burden of OBPDs.

Acute intestinal infections remain one of the leading causes of morbidity among children under five years of age and represent an important public health challenge in both developed and developing countries. Although these infections often share similar clinical manifestations, their etiological structure, severity, diagnostic accessibility, treatment approaches, and prevention strategies differ considerably depending on socioeconomic conditions, sanitation, healthcare infrastructure, and vaccination coverage. Aim: This review aims to summarize current data on the epidemiology, etiology, clinical presentation, diagnosis, treatment, and prevention of acute intestinal infections in children aged 1–5 years, as well as to provide a comparative analysis of approaches in countries with different income levels. Methods: A review of scientific literature focused on acute intestinal infections in young children was conducted. Source selection included full-text assessment. The extracted data were summarized descriptively according to pathogen groups: viral, bacterial, and protozoal infections. A PRISMA flow diagram was used to present the source selection process. Results: The reviewed literature indicates that viral pathogens, particularly rotavirus and norovirus, are among the leading causes of acute gastroenteritis in children under five years of age. According to Global Burden of Disease 2021 estimates, approximately 392.8 million diarrhoeal episodes and 0.34 million deaths occurred among children under five years of age globally in 2021, with mortality disproportionately concentrated in sub-Saharan Africa and South Asia. Bacterial infections, including Shigella and diarrheagenic Escherichia coli, are less frequent but are more often associated with invasive disease, severe diarrhea, and systemic complications. Protozoal infections, including Giardia lamblia, may contribute to prolonged diarrhea, especially in children with malnutrition or weakened immune status. Substantial regional differences were identified in pathogen distribution, antimicrobial resistance, diagnostic capacity, access to healthcare, and vaccination coverage. In developing countries, the disease burden remains strongly associated with limited access to safe water, sanitation, timely diagnosis, and appropriate medical care, whereas in developed countries acute intestinal infections more commonly contribute to outbreaks, emergency department visits, and hospitalizations. Conclusions: Acute intestinal infections in children aged 1–5 years remain an important global health burden with substantial regional disparities. Effective prevention and control require context-specific strategies combining high vaccination coverage, improved water, sanitation and hygiene, timely pathogen-specific diagnosis, rational antimicrobial use, and strengthened surveillance, with particular priority given to high-burden and resource-limited settings.
