Water security is a significant challenge for the Saudi Arabia Kingdom’s development and stability, affecting other economic sectors beyond the water sector. Insufficient water resources are causing economic and social crises; addressing this issue is crucial for the country’s growth and stability. This study aims to manage water resources in central Saudi Arabia (Wadi AS SAHBAA) through a two-level approach. The first level involves extracting rainfall amounts from satellite imagery to predict future rainfall intensity using PERSIANN-CCS-CDR data. The second level focuses on monitoring groundwater recharge using geographic information systems (GIS) and remote sensing techniques. The study further seeks to understand rainstorm behavior influenced by climate variability and applies geomatics techniques for quantitative analysis. The results show that the Wadi AS SAHBAA basin receives an annual precipitation of 116.6 mm/year and mean annual precipitation of 9.7 mm. The year 2019 experienced the highest recorded precipitation, reaching 222.3 mm and mean annual precipitation of 18.5 mm. Between 2013 and 2019, the AS SAHBAA region experienced increased rainfall driven by intense storm events; however, it declined during the period 2020–2022. Moreover, 2021 recorded the lowest annual precipitation of 53.8 mm with mean annual precipitation of (4.5 mm), possibly linked to reduced storm activity due to the COVID-19 pandemic. The study uses several methods to estimate groundwater recharge from rainfall and concludes that the average infiltration during 2013–2022 was varying from 1.59–36.63 mm, representing about between 1.03 and 28.5% of total rainfall. This is reflected in groundwater storage capacity, which ranges from approximately 1.65 to 38.27 million m³ yearly. This study provides a framework for monitoring precipitation and groundwater recharge and offers practical recommendations for regional development and sustainable water management. Full article

Depression has become a major concern for educational institutes due to its increasing incidence and detrimental impacts on students’ well-being. However, its global prevalence in the context of tertiary education remains unclear. This umbrella review summarised existing meta-analyses and systematic reviews to examine the worldwide prevalence of depression among university students. Several sociodemographic and methodological factors, including differences in depression prevalence before, during, and after COVID-19, were examined as moderators. Structured and exhaustive searches were conducted in five bibliographic databases and five journals, alongside two sources of grey literature. A total of 61 meta-analyses and systematic reviews were included in the final synthesis. Review-level sample sizes ranged from 823 to 8,238,954 (Mdn = 24,047), covering all inhabited continents and a broad range of countries across high-, middle-, and low-income settings. The global median prevalence of depression across the included reviews was 32.00%, with reported estimates ranging from 11.00% to 63.00%. Analysis of specific populations highlighted greater vulnerability among female students and those studying in Asia compared to Europe. The pandemic was shown to have contributed to the increase in depression prevalence among university students. Given this high prevalence of depression, there is an imperative need for educational institutions to prioritise mental well-being. Full article

The COVID-19 pandemic severely disrupted tourism globally, with considerable variation in impact and recovery across regions. This study examines how tourism demand, revenue, employment, and transport evolved in the Visegrád Four (V4) countries—Czechia, Hungary, Poland, and Slovakia—between 2015 and 2025, assessing recovery speed and sectoral resilience across nine indicators. The modelled window varies by indicator: 2015–2023 for revenue indicators, 2015–2024 for visitor-flow indicators, and 2015–2025 for employment and air passenger indicators. Annual data from Eurostat and the Hungarian Central Statistical Office were analysed using descriptive comparative methods, linear mixed-effects models, and interrupted time series analysis with counterfactual projections. All indicators showed sustained pre-pandemic growth followed by a statistically significant 2020 shock. International demand fell roughly twice as sharply as domestic demand, and air passenger traffic suffered the largest absolute collapse. Revenue recovered fastest, surpassing pre-pandemic levels by 2023–2024 in all countries, while guest-volume recovery is projected only by 2025–2027. Part-time employment remained below 2015 levels in three of four countries despite volume and revenue recovery, indicating structural labour market adjustment. Slovakia consistently showed non-significant post-shock recovery slopes in seven of nine indicators, emerging as the region’s weakest performer. These findings indicate that COVID-19 produced uneven, revenue-led recovery across V4, and the employment paradox and Slovakia’s underperformance underscore the need for diversified, evidence-based tourism crisis management.

Migrant agricultural workers (MAWs), predominantly individuals from countries in the Global South, play a vital role in maintaining Canadian food security. Employed in low-income positions across the country, they often face workplace hazards and numerous occupational health and safety (OHS) challenges related to long working hours, limited access to OHS information, gaps in knowledge, structural power imbalances with employers, and language and cultural barriers. This pilot study explored the knowledge, attitudes, and perceptions of OHS issues among MAWs in Southern and Eastern Ontario during the COVID-19 pandemic. Participants completed survey questions on working conditions, OHS hazards, and living conditions. A total of 93 questionnaires were completed, 55 by Spanish-speaking and 38 by English-speaking individuals, with 91% of respondents identifying as male. Several participants reported awareness of positive COVID-19 cases in their workplaces, and some indicated having experienced OHS-related illnesses or injuries but felt uncomfortable reporting them to supervisors. Knowledge of OHS rights varied, with a notable minority uncertain about their entitlement to sick leave. The findings indicate a need for further research and targeted interventions to strengthen health and safety practices among MAWs and to ensure they are informed, protected, and supported in exercising their workplace rights.

Background/Objectives: The global health crisis of the COVID-19 pandemic in 2020 severely impacted healthcare systems, particularly affecting cancer patients, including those with lung cancer. Understanding the pandemic’s effects on lung cancer diagnosis is important for providing guidelines for future similar crises. Methods: A comprehensive search was conducted using the SCOPUS and PubMed databases, including keywords such as ‘COVID-19 pandemic,’ ‘lung cancer,’ ‘diagnosis,’ and ‘screening.’ In the initial screening phase, studies were selected based on their title and abstract, followed by the removal of duplicates. A second round of full-text screening was then performed using predefined inclusion and exclusion criteria. Specific checklists were applied to ensure methodological quality. Results: Out of 564 articles, 78 met the inclusion criteria and were grouped according to changes in lung cancer incidence, screening and diagnostic procedures, and staging during the COVID-19 pandemic compared to pre-pandemic. Multiple studies reported an average decline of 20% in newly diagnosed lung cancer cases, alongside significant decreases in screenings, follow-ups, and diagnostic procedures. In contrast, only two studies reported an increase in lung cancer incidence, and three studies reported increases in screening or diagnostic activity. Eight studies reported a shift toward more advanced-stage diagnoses and fewer early-stage detections, while four studies observed a decrease in advanced-stage lung cancer during the pandemic compared to pre-pandemic years. Conclusions: Studies show that overall, the COVID-19 pandemic disrupted lung cancer diagnosis in many countries, highlighting the need for stronger healthcare systems that can support crisis response and equitable care.

Background/Objectives: Child social vulnerability is a multidimensional phenomenon influenced by poverty, material deprivation, inequality, and institutional protection. This study analysed child and adolescent social vulnerability in Europe between 2017 and 2023 and developed a Child Social Vulnerability Index (CSVI). Methods: A longitudinal ecological study was conducted using Eurostat country-year data from European countries. Indicators included severe child poverty, severe material deprivation, income inequality (Gini index), preventive healthcare expenditure, and social protection expenditure. Descriptive, longitudinal, principal component, and cluster analyses were performed. Results: The findings revealed substantial differences in child social vulnerability across European countries. Poverty, material deprivation, and inequality were strongly associated, supporting the multidimensional nature of vulnerability. Principal Component Analysis supported the internal structure of the child Social Vulnerability Index (CSVI), identifying two components that explained 76.35% of the variance. The CSVI showed a very high correlation with the first principal component (r = 0.97, p < 0.001) confirming its structural consistency. Longitudinal analyses revealed a significant decline in child social vulnerability between 2017 and 2023 with an additional reduction during the COVID-19/post-COVID period. Cluster analysis identified three distinct European vulnerability profiles based on the CSVI and institutional protection dimension. Conclusions: Child social vulnerability in Europe is shaped by the interaction of socioeconomic inequalities and institutional protection mechanisms. The CSVI provides a useful tool for monitoring vulnerability and informing policies to reduce inequalities and promote child and adolescent well-being. Full article

While conventional theories posit that stronger institutions buffer economies against crises, the COVID-19 pandemic presents a puzzle: despite substantial variation in institutional capacity, the global economic contraction of 2020 was both severe and widespread. Motivated by this puzzle, we constructed a global panel dataset from 2014 to 2024 and employed two-way fixed-effect estimation with Driscoll–Kraay robust standard errors to examine the differential role of state capacity across COVID-19 crisis phases. The results confirm that the shock caused by the pandemic reduced GDP per capita growth across countries, with the Americas experiencing disproportionately deeper contractions and stronger rebounds relative to other regions. Most importantly, the findings reveal a temporal asymmetry in institutional effectiveness: our constructed composite resource-based measure of state capacity does not mitigate the initial economic contraction but exerts a positive, statistically significant effect on post-pandemic recovery. Unsurprisingly, model re-estimation with the conventional perception-based measure of state capacity fails to replicate this dynamic, underscoring the importance of measurement strategy in institutional research. These results challenge the assumption that institutions uniformly buffer shocks, demonstrating instead that state capacity is more consequential for recovery than crisis prevention. Full article

This paper examines changes in the macroeconomic indicators of the member countries of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) following their accession to the agreement. This study aims to identify shifts in the structural comparability of national economies and to assess the processes of macroeconomic convergence in the context of sustainable development. To achieve this objective, reference pools of CPTPP member countries are constructed, and their digital profiles are developed based on key macroeconomic indicators and grouped into three blocks: (1) indicators of economic growth and the state of the real sector, including GDP (constant 2015 US$), GDP growth, annual %, gross capital formation, % of GDP, unemployment, total % of total labor force, and national estimate; (2) indicators of foreign economic activity and trade openness, including exports of goods and services, % of GDP, imports of goods and services, % of GDP, external balance on goods and services (% of GDP), foreign direct investment, net inflows, % of GDP, and trade, and % of GDP; (3) indicators of financial and macroeconomic stability including inflation, consumer prices, annual %, central government debt, % of GDP, and gross savings, and % of GDP. Based on the digital profiles, similarities/differences in the economies were examined by applying linear discriminant analysis (LDA). The empirical framework covers two periods: (1) 2013–2017 (pre-accession) years and (2) 2019–2023 (post-accession) years. The results indicate that the economies of member countries in 2013–2017 exhibited a high degree of heterogeneity. In contrast, the 2019–2023 period demonstrates a tendency toward partial convergence of macroeconomic parameters, as evidenced by a reduction in distances between country profiles in the discriminant space. While interpreting the results, it is acknowledged that the 2019–2023 period coincided with the effects of the global crisis caused by the COVID-19 pandemic, which significantly impacted international trade dynamics. For most countries, this period was characterized by a decline in several macroeconomic indicators and investment activity, an increase in debt burdens, and enhanced heterogeneity in economic dynamics, which was taken into account when interpreting macroeconomic convergence processes within the CPTPP. The scientific novelty of the study lies in its application of an approach based on the analysis of the structural similarity of the macroeconomic profiles of CPTPP countries, which complements traditional assessments of the effects of economic and trade integration. The practical significance of the findings is associated with their potential use in evaluating the prospects for CPTPP expansion and in modeling alternative scenarios of participation and sustainable development within international trade agreements under conditions of global economic transformation.

During the coronavirus disease-2019 (COVID-19) pandemic, wastewater-based surveillance (WBS) gained renewed importance by enabling nationwide assessment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) circulation independent of individual testing. In Germany, WBS was established by a series of initiatives, including the AMELAG project, established in 2022. As the pandemic phase waned, the extensive surveillance infrastructure—comprising around 170 wastewater treatment plants (WWTPs)—was scaled down. A subset of 53 WWTPs was selected by a hierarchical set of criteria to ensure continuation of WBS in 2025, resulting in a reduced population coverage (26% instead of 37%), preserving the monitoring of infection dynamics while improving operational efficiency. The multi-stage selection approach integrated operational experience and performance data of WWTPs collected between November 2022 and July 2024, including wastewater characteristics and laboratory quantification success, minimum population coverage across all administrative regional states of the country, and statistical quality metrics such as the frequency of outliers and implausible inflexion points or the deviation from LOESS regression trends. Additional consideration was given to sites of extended research relevance. Reducing the number of WWTPs by more than two-thirds did not result in notable deviations in the aggregated national SARS-CoV-2 viral load profile. However, the evaluation was limited to SARS-CoV-2 data, despite ongoing expansion of the WBS network to include additional pathogens. Overall, the data-driven site-selection framework, developed from scientific and operational criteria, ensures the sustainable continuation of the nationwide WBS system. Full article

This study assesses liquidity, profitability, and working capital management (WCM) strategy in Polish manufacturing companies in the pressure-casting industry, drawing on evidence from the pre-COVID-19, COVID-19, and Russia–Ukraine war periods. Using panel data from 19 companies representing 90% of the Polish aluminum diecasting industry, we employ non-parametric tests (Mann–Whitney U and Kruskal–Wallis) to analyze the data. The period after the COVID-19 crisis coincides with the Russian–Ukrainian war. These countries are Poland’s neighbors. This period of uncertainty for Poland has led to supply chain disruptions and reduced investments. For manufacturing companies, this is dangerous because they have limited development opportunities. The results indicate the adoption of a conservative WCM strategy in Polish aluminum foundries during the pre-COVID-19, COVID-19, and Russia–Ukraine war periods, characterized by increased inventory levels, extended operating cycles in large firms. Additionally, the results showed reduced the level of receivables in large companies and visible decrease in the level of financial liquidity and profitability—however, these differences are not statistically significant. Polish aluminum foundries are adapting their WCM strategies toward an optimal, conservative approach that incorporates both safe and risky elements to ensure continued operations and profits. In addition, larger Polish aluminum foundries exhibit distinct liquidity patterns relative to smaller foundries, particularly in indicators of inventory, receivables, and fixed assets. In addition, the Russia–Ukraine war period exhibits distinct liquidity characteristics in Polish aluminum foundries compared with the COVID-19 and pre-COVID-19 periods, particularly in inventory turnover and operating cycle. The results of this study offer several novel contributions to the existing literature on financial security indicators by examining unexplored factors related to size and period. The results of this study have several practical implications for business leaders seeking to adopt an optimal liquidity, profitability, and WCM strategy. Full article

Background: The COVID-19 pandemic caused disruptions in HPV vaccination and may have severely undermined global cervical cancer prevention, posing long-term risks to controlling cervical cancer and other HPV-related diseases. Objective: We conducted a scoping review to map and synthesize available evidence on how the COVID-19 pandemic has affected human papillomavirus (HPV) vaccination programs in low- and middle-income countries (LMICs) focusing on changes in vaccine delivery and coverage, determinants of uptake, economic and programmatic consequences and vaccine hesitancy. Methods: Inclusion criteria were limited to studies published in the English language between January 2020 to May 2025, and followed JBI and Arksey & O’Malley’s scoping review guidelines. The review proceeded through three stages: database searches, gray literature and citation tracking and used a PRISMA-ScR checklist to guide narrative and tabular synthesis. Results: A total of 1063 records, 57 studies were included in the final analysis, and these were spread out across 37 low- and middle-income countries (LMICs) mainly in Africa, Asia, and Latin America. Our analysis revealed that HPV vaccination coverage declined substantially during the COVID-19 pandemic, with reductions of up to 90% reported across the included studies, in the context of school closures, workforce redeployment, and supply-chain disruptions. Recovery efforts also faced major barriers including vaccine hesitancy, misinformation about COVID-19 vaccines, and travel restrictions. Strategies like digital tools, mobile clinics, and community health workers showed promise alongside integrated school- and facility-based approaches, although there is limited evidence on cost-effectiveness and long-term sustainability of these strategies. Conclusions: HPV vaccination in LMICs was significantly disrupted by the COVID-19 pandemic due to unreliable vaccine supply chains, health-worker shortages, and challenges tied to school-based vaccine delivery. Although recovery methods show potential, longer observation periods are needed to determine their full effectiveness. Full article

Background/Objectives: COVID-19 may result in persistent symptoms, some of which can be disabling, referred to as post-acute sequelae of SARS-CoV-2 (PASC, or long COVID). The growing recognition of PASC as a public health challenge underscores the need for comprehensive studies of its course, risk factors, and clinical outcomes. This multicentric study aimed to compare the prevalence, symptom spectrum, and functional impact of PASC in two patient groups: those hospitalized with COVID-19 and those managed exclusively in ambulatory care. Methods: Molecular, clinical, and demographic data were obtained from 319 patients diagnosed with COVID-19 in seven European countries. Patients were classified as PASC in accordance with the WHO definition. Results: PASC is more frequent and severe among hospitalized patients, while ambulatory patients present with milder but prolonged symptoms. Categorical age analysis suggests that older age was associated with a higher incidence of PASC, highlighting the need for multidisciplinary management and targeted support. Conclusions: Our findings highlight distinct differences in the presentation and impact of PASC across patient groups, with important implications for individualized care, multidisciplinary management, and effective healthcare planning in the post-pandemic era.

The COVID-19 pandemic contributed to more severe and frequent intimate partner violence (IPV) among victims, and less availability of services; however, this research has largely been conducted on only female victims. We investigated the COVID-19 pandemic’s contribution to more severe and frequent IPV among male victims, barriers to getting help, and factors contributing to both increased severity/frequency and barriers. Participants included 318 male IPV victims from English-speaking Western countries who reported being the victim of IPV during the pandemic. They completed a Qualtrics questionnaire asking about their IPV experiences, mental health, COVID-19-related experiences in general and IPV experiences in specific. Overall, 47.8% of the participants experienced an increase in frequency and/or severity of IPV victimization, with help-seeking barriers, job loss, being confined to the house with their aggressor, and prior trauma independently predicting increases. Also, 75.5% reported one or more barriers to accessing help; such barriers were independently predicted by increased severity/frequency of IPV, financial strain, relationship length, being married, using marijuana, severe depression, prior trauma, IPV stigma, and coercive control victimization. Results are discussed in terms of their consistency with the literature on female victims, and the need for gender inclusive research, service provisions, and service recommendations in light of crises such as the COVID-19 pandemic.

Respiratory syncytial virus (RSV) imposes a substantial burden of severe acute respiratory infection (SARI), especially in young children and the elderly. Methods: We describe RSV epidemiology among hospitalized SARI patients at the Ibn Sina University Hospital Center (Rabat, Morocco) from 1 January 2021, to 31 December 2025, using multiplex PCR (BioFire^® RP2.1plus or Xpert^® SARS-CoV-2/Flu/RSV). Results: Among 4604SARI samples, RSV prevalence was 16.1% (739/4604), predominantly pediatric (88.6%, p < 0.001), with peak burden in infants <6 months (70.4% of cases, p < 0.001). Pediatric prevalence was 28.3% (655/2316) vs. 3.8% (84/2204) in adults (p < 0.001), with predominance in the elderly ≥60 years (51/1041, 4.9%). Co-infections occurred in 46.7% (310/665) of FilmArray-tested positives (total = 665), led by rhinovirus/enterovirus (198/310, 63.9%), and were significantly higher in children (48.5%, p < 0.001). RSV peaked in winter (51.6%), except for summer dominance in 2021 (52.5%), reflecting COVID-19 non-pharmaceutical intervention effects. Conclusions: These data establish Morocco’s first comprehensive RSV surveillance baseline, highlighting post-pandemic epidemiological shifts. As maternal vaccines and monoclonal antibodies emerge, these data inform optimal implementation in low- and middle-income countries (LMICs). Full article

Background/Objectives: Individuals with alcohol use disorder (AUD) and tobacco use disorder (TUD) are at increased risk for severe COVID-19 outcomes. However, real-world evidence on vaccine effectiveness (VE) in these populations remains limited, particularly in low- and middle-income countries. This study aimed to evaluate the effectiveness of three or more COVID-19 vaccine doses against mortality in hospitalized patients with AUD and TUD in Brazil. Methods: This retrospective cohort study used data from the SIVEP Gripe database, a national surveillance system of hospitalized COVID-19 cases in Brazil. The study included adults aged ≥18 years with confirmed SARS-CoV 2 infection between February 2020 and June 2025. The intervention was defined as receipt of three or more vaccine doses (fully vaccinated) versus no doses (unvaccinated). Propensity score matching was performed separately for AUD and TUD cohorts. Vaccine effectiveness was estimated using McNemar’s test for paired samples, and the average treatment effect (ATE) and number needed to vaccinate (NNV) were calculated. Results: Among 2,184,723 hospitalized patients, 12,115 had AUD and 45,679 had TUD. After matching, VE against mortality was 42% (95% CI: 27.5–53.5) in the AUD group and 52.6% (95% CI: 46.5–58.1) in the TUD group, compared to 58.5% and 58.9% in their respective non-exposed counterparts. The ATE was consistent across groups (approximately −0.12), and the NNV to prevent one death was 8 (95% CI: 6–15 for AUD; 7–12 for TUD). Conclusions: Although VE was attenuated in individuals with AUD and TUD compared to the general population, the absolute benefit of vaccination remained substantial. Full article
