Changes in spinal curve during dentistry studies measured with a Spinal Mouse device: A five-year prospective study.

Musculoskeletal disorders (MSDs) often arise and develop during dentistry studies. The most affected regions are related to the spine. Possible associations between spinal curve parameters and MSDs have not yet been investigated amongst dentistry students. This longitudinal observational study aimed to determine whether spinal curve changes during dentistry studies, analyse the relationship between objective findings and subjectively declared MSDs and compare spinal curve parameters with those published in the literature. Seventy-three dentistry students answered a questionnaire on MSDs, and were examined using the Spinal Mouse® device at the beginning, in the middle, and at the end of their 5-year study. The spinal curve exhibited a gender diversity in the lumbar lordosis angle, sacrum inclination, and thoracolumbar ratio. From the first to fifth study year, we observed an increase in the range of motions in the sagittal and frontal planes, an increase in the maximal extent of right lateral inclination, and a decrease in maximal left lateral inclination. Whole-spine backward inclination increased only in women, and forward sacral inclination decreased. No statistically significant relationships were found between the objective findings and subjectively declared MSDs. The spinal curve shape differed between men and women and changed during dentistry studies. No objective markers or predictors of MSDs were found amongst the dentistry students. These findings can serve as a benchmark for further studies on the association between MSDs and objective findings.

Results of patch testing propolis in the European baseline series: A 4-year retrospective study.

Propolis was added to the European baseline series (EBS) in 2019. To investigate the frequency and relevance of positive patch tests to propolis in the EBS and to study co-reactivities. Retrospective study in patients patch tested between June 2019 and November 2023 in a university hospital in Amsterdam, The Netherlands. Of 3134 consecutive patients, 299 (9.5%) had a positive reaction to propolis 10% pet. Only nine reactions (3%) were judged to be clinically relevant. There were significant co-reactivities to Myroxylon pereirae resin (balsam of Peru), colophonium, fragrance mixes 1 and 2, and to limonene and linalool hydroperoxides. A steep increase in rates of positive reactions to propolis was observed from 2020 to 2023. This was highly likely the result of the replacement of Chinese propolis with Brazilian propolis by the manufacturer. Positive patch tests for propolis are very frequent in Amsterdam, but only a few of these reactions are relevant. Most are probably (pseudo-)cross-reactions in patients with fragrance allergies. Propolis in the EBS has very limited value for dermatologists and patients in The Netherlands. Changes in patch test materials should be provided to all users to avoid misinterpretation of patch test results.

Analysis of different factors on dental students' perception of a flipped classroom model: A 6-year follow-up study.

To evaluate different factors affecting two different cohorts of dental students' perceptions with the flipped classroom (FC) model in a preclinical dental course over six years. In 2016 (cohort #1) and 2022 (cohort #2), second-year dental students participated in FC model in a preclinical dental course consisting of pre-class recorded videos and lectures along with classroom interactive exercises. Students then completed an anonymous pen-and-paper survey evaluating three factors influencing students' overall study experience with the FC model. Survey responses from cohort #1 and cohort #2 were compared to assess the effect of generation, student demographics and COVID-19 pandemic on students' perceptions. When asked to rate the FC experience out of 5, the mean ratings of cohort #1 and cohort #2 were 4.3 (±0.9) and 4.0 (±0.8), respectively. Cohort #2 preferred viewing slides and videos prior to class and had a higher agreement that pre-class course materials were beneficial to class preparation. Conversely, cohort #1 had a higher agreement that in-class discussion and exercises helped them to learn course content. From cohort #2, 88.6% of males and 71.6% of females preferred the FC approach over traditional lecture. Both cohorts reported positively with the FC model of teaching. Cohort #2 had higher positive reports with the pre-class work and cohort #1 had a higher positive report with in-class work. Course design should reflect the students' points of view and learning perspectives with careful consideration of the student population in the classroom.

Intraarticular gold microparticles using hyaluronic acid as the carrier for hip osteoarthritis. A 2-year follow-up pilot study

We recently conducted a pilot study in which we discovered that introducing metallic gold microparticles into the knee joint can help reduce pain caused by osteoarthritis for up to two years. Additionally, we identified significant proteomic changes in the synovial fluid and serum within eight weeks of the procedure. In this study, we aimed to evaluate whether there may be a clinical relevant effect of intra-articular injection of gold microparticles on hip osteoarthritis. A cohort of 22 patients, aged ≥ 18 years, with pain ≥ 3 months, and Kellgren-Lawrence OA grade 2–4, were included. Metallic gold 20 mg, 72.000 pieces, 20–40 µ-meter BerlockMicroImplants (BMI) were injected into the hip joint using hyaluronic acid as the carrier. In total, we treated 26 hip joints. The primary outcome was the Western Ontario and McMaster Universities Arthritis Index (WOMAC). WOMAC pain decreased from 11 (2–20 to 3 (0–8), stiffness from 6 (0–8) to 1 (0–4), and activity from 43 (18–68) to 11 (0–27), all P = 0.0001. When adjusting for the minimally relevant differences, the P-values were 0.0015 for WOMAC pain, 0.26 for stiffness, and 0.011 for activity. Combined intraarticular treatment with metallic gold microparticles and hyaluronic acid may improve hip joint pain and function. Joint stiffness did not improve when assessed against the minimal clinically relevant difference. This study suggests a basis for a future placebo-controlled randomized trial of gold microparticles and hyaluronic acid in hip osteoarthritic patients.

Heart rate variability as a biomarker for transdiagnostic depressive and anxiety symptom trajectory in adolescents and young adults.

Internalizing psychopathology is associated with abnormalities in heart rate variability (HRV). Lower HRV that reflects reduced parasympathetic nervous system activity has been observed in depressive and anxiety disorders. Existing studies predominantly used categorical rather than dimensional approaches, the latter of which better addresses clinical comorbidity and heterogeneity. Moreover, there is little evidence on the role of HRV in longitudinal symptom trajectory in adolescents and young adults. The current study examined the association between HRV and internalizing symptom trajectory using a dimensional approach-the tri-level model of depression and anxiety. Adolescents and young adults (N = 362) were recruited in a 3-year longitudinal study, where they completed electrocardiogram recordings and self-report symptom questionnaires. Multilevel modeling was conducted with high-frequency power bands (HF power) of interbeat intervals at baseline as the predictor, and tri-level symptom factors over 3 years as the outcome. HF power significantly predicted the trajectory of the broad General Distress symptom factor, but not the intermediate Fears or Anhedonia-Apprehension symptom factors. Higher HF power was associated with a decline in General Distress over time. This association was held when neuroticism, other tri-level symptom factors, and demographic variables were covaried. That is, greater parasympathetic nervous system activity at baseline was significantly associated with a greater decline in the broad internalizing symptom factor, but not symptom factors that are more specific to depressive or anxiety disorders. Parasympathetic activity, therefore, may be a transdiagnostic biomarker for internalizing symptoms in adolescents and young adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Incidence, diagnostics, therapeutic management and outcomes of paediatric intestinal pseudo-obstruction in the Netherlands: A 20-year retrospective cohort study.

To describe incidence, clinical course, diagnostic and therapeutic management and long-term follow-up of paediatric intestinal pseudo-obstruction (PIPO) in the Netherlands between 2000 and 2020. Multicenter, national, retrospective, observational study including patients aged <18 years diagnosed with PIPO and treated between 2000 and 2020 in Dutch academic medical centres. Outcomes included demographics, incidence, symptoms, diagnostic- and treatment methods used during follow-up, number of hospital admissions and mortality. Between 2000 and 2020, 43 children (median age 120 months, range 13 - 301, 54% female) were diagnosed with PIPO in the Netherlands. Mean incidence was 0.008/100,000/years (range 0/100 000-0.029/100 000). Twenty-six patients developed PIPO in the neonatal period. Initial symptoms were vomiting (n = 21/35, 60%) and abdominal distension (n = 14/35, 40%). Diagnostic strategies included imaging, manometry, histopathology, metabolic- and genetic screening, endoscopy and exploratory surgery. Treatment was divided in nutritional support, pharmacotherapy, colonic irrigation and surgical interventions, of which nutrition and surgery were the cornerstones for care. During the observed study period, the median number of hospital admissions was 22.5 (range 1-176) with a median of 157.5 days (range 3-840) during 20-year follow-up. Two patients (6%) died: one from sepsis and one due to a severe underlying neurological disease. Heterogeneity in diagnostic- en treatment methods existed between patients. PIPO is a rare, long-lasting complex disease requiring a high number of diagnostic and therapeutic interventions and hospital admissions. However, mortality rate is relatively low. Based on our results, we recommend centralization and standardization of care for this complex rare disease.

Biochemical analysis of soft tissue infectious fluids and its diagnostic value in necrotizing soft tissue infections: a 5-year cohort study

BackgroundNecrotizing soft tissue infections (NSTI) are rapidly progressing and life-threatening conditions that require prompt diagnosis. However, differentiating NSTI from other non-necrotizing skin and soft tissue infections (SSTIs) remains challenging. We aimed to evaluate the diagnostic value of the biochemical analysis of soft tissue infectious fluid in distinguishing NSTIs from non-necrotizing SSTIs.MethodsThis cohort study prospectively enrolled adult patients between May 2023 and April 2024, and retrospectively included patients from April 2019 to April 2023. Patients with a clinical suspicion of NSTI in the limbs who underwent successful ultrasound-guided aspiration to obtain soft tissue infectious fluid for biochemical analysis were evaluated and classified into the NSTI and non-necrotizing SSTI groups based on their final discharge diagnosis. Common extravascular body fluid (EBF) criteria were applied.ResultsOf the 72 patients who met the inclusion criteria, 10 patients with abscesses identified via ultrasound-guided aspiration were excluded. Based on discharge diagnoses, 39 and 23 patients were classified into the NSTI and non-necrotizing SSTI groups, respectively. Biochemical analysis revealed significantly higher albumin, lactate, lactate dehydrogenase (LDH), and total protein levels in the NSTI group than in the non-necrotizing SSTI group, and the NSTI group had significantly lower glucose levels and pH in soft tissue fluids.In the biochemical analysis, LDH demonstrated outstanding discrimination (area under the curve (AUC) = 0.955; p < 0.001) among the biochemical markers. Albumin (AUC = 0.884; p < 0.001), lactate (AUC = 0.891; p < 0.001), and total protein (AUC = 0.883; p < 0.001) levels also showed excellent discrimination. Glucose level (AUC = 0.774; p < 0.001) and pH (AUC = 0.780; p < 0.001) showed acceptable discrimination. When the EBF criteria were evaluated, the total scores of Light’s criteria (AUC = 0.925; p < 0.001), fluid-to-serum LDH ratio (AUC = 0.929; p < 0.001), and fluid-to-serum total protein ratio (AUC = 0.927; p < 0.001) demonstrated outstanding discrimination.ConclusionBiochemical analysis and EBF criteria demonstrated diagnostic performances ranging from acceptable to outstanding for NSTI when analyzing soft tissue infectious fluid. These findings provide valuable diagnostic insights into the recognition of NSTI. Further research is required to validate these findings.

Treatment Outcomes of Four-Implant-Retained Maxillary Palateless Overdenture: A 5-Year Observational Study.

Palateless overdentures (PLODs) provide advantages of improved taste perception and retention over conventional dentures. We aimed to evaluate 5-year outcomes of four implant maxillary PLODs. In this prospective observational study, edentulous participants were enrolled. A new conventional maxillary denture was prepared followed by implant placement and insertion of four implant retained maxillary PLOD. Oral health quality of life was assessed using the 49-item Oral Health Impact Profile (OHIP-49) at multiple intervals over 5 years along with biological and mechanical outcomes. Nine patients were evaluated at year 5. The mean age was 68 years, and six of the nine patients were males. The cumulative survival rate of implants was 100% while the implant success rate was 86%. Nylon retentive replacement was the most common encountered complication noted approximately four times per patient over 5 years. From a mean OHIP-49 severity score of 71.2 at baseline, severity scores decreased to 23.9 (p < 0.001) at year 1, denoting a clinically meaningful and statistically significant improvement in oral health quality of life. The lowered OHIP-49 severity scores remained stable throughout 5 years of follow-up. Four implant supported maxillary overdenture appears to have good patient perceived, biological and mechanical outcomes over 5 years. Fully powered studies are needed to replicate these findings.

The longitudinal retention of STEM students through a multifaceted mentoring and tutoring program

ABSTRACT This 4-year longitudinal study identified the impact of a multifaceted mentoring and tutoring program on the retention and graduation rates of a diverse body of undergraduate college students enrolled in high-risk science courses. Findings revealed that the program was successful in increasing the retention and graduation rates of students who participated in the program. All student cohorts tutored through the program demonstrated significantly higher survival rates when they increased their usage of tutoring, threby demonstrating greater survival to retention. Notably, cohorts with high as well as those with low academic competencies achieved the highest 4-year retention survival probabilities when they participated in six or more tutoring sessions. Additionally, through further analysis, a predictive model derived from this research offers a valuable tool that can be strategically utilized to improve retention and/or graducation outcomes of at-risk populations and underrepresented populations in STEM education.

Unravelling self-regulation in early childhood: protocol for the longitudinal SPROUTS study

BackgroundEnough is known about self-regulation to establish it as a priority target for education and intervention efforts beginning in early childhood, yet not enough to meaningfully and reliably alter developmental trajectories. Rather than resigning our aspirations, we need more nuanced and integrative understanding of self-regulation abilities and change.MethodsLaunching in 2024, SPROUTS is a 3-year longitudinal study of early self-regulation, beginning in the pre-school period (3–5 years old at Wave 1) with retrospective data back to birth and annual data collection across the transition to school period (ages 5–7 years at Wave 3). Data will be collected on children’s self-regulation, related abilities, outcomes, as well as prior and current contexts. One nested study within each Wave–that contributes complementary insights via supplementary and in-depth methods and data–will enable further exploration of contemporary issues related to self-regulation.DiscussionInsights generated can potentiate more effective intervention and education efforts by: improving intervention cost-benefit ratios; identifying likely mechanisms of change; easing burdens of unhealthy and antisocial behaviours associated with low self-regulation; and, most importantly, contributing to giving children the best early start to life. These benefits are timely in the context of intense policy and educational interest in fostering children’s self-regulation.Trial RegistrationOpen Science Framework: osf.io/maqdg.

Visual analysis of postmortem interval estimation trends and collaborative networks: a 15-year study (2006-2020).

Utilizing a visual analysis of the literature on postmortem interval (PMI) estimation indexed by Web of Science (WOS), this study investigates developmental trends and research hot points across each 5-year period from 2006 to 2020. Additionally, collaborative efforts among authors, countries, and institutions were examined. Research hot points, high-frequency keywords, authors, countries and institutions in relevant papers were analyzed using CiteSpace.5.7.R2 information visualization analysis software over the past 15 years. The literature related to PMI estimation has witnessed consistent growth over time. In the keyword co-occurrence network, several impactful terms stand out, including blowfly, mitochondrial DNA, and emerging concepts like virtual autopsy. Technological advancements, such as RNA stability analysis and virtual autopsy tools, have played a pivotal role in shaping the direction of PMI research. Scientific research institutions dominate the high-frequency affiliations within the institutional cooperative network. Additionally, the country cooperative network exhibits a trend of co-occurrence and multi-clustering. As science and technology continue to advance, traditional PMI estimation methods mature while novel interdisciplinary approaches drive innovation. By identifying emerging trends and research hotspots, this study provides a roadmap for future investigations, guiding researchers toward new opportunities in PMI estimation.

Association between renal function and the Treatment of Diabetic Macular Edema in Long-Term Cohort Study

To determine the correlation between the severity of chronic kidney disease (CKD) and treatment of diabetic macular edema (DME). The retrospective 2-year cohort study included eyes with DME confirmed using spectral-domain optical coherence tomography in Taipei Veterans General Hospital, Taiwan, between 2010 and 2020. All the eyes were treated with an intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) during regular follow-up around 2 years. They were categorized into 3 different groups: an estimated glomerular filtration rate ≥ 60 (mL/min per 1.73 m2) (group A), < 60 (group B), and patients undergoing hemodialysis (group C). The main outcome measures were (1) visual improvement, (2) structural improvement, and (3) the injection frequency of anti-VEGF in the different groups. In this study, 167 eyes from 120 patients were enrolled. Compared with groups B and C, the eyes in group A experienced the only significant visual improvement at month 3, month 6, and month 12 (P = 0.0001, 0.0002, 0.0013, respectively). The presence of subretinal fluid and intraretinal cysts was significantly decreased in groups A and B. In the treatment frequency analysis, the number of injections was the highest in group A and lowest in group C during the study period (P = 0.04). The severity of CKD had an impact on the DME treatment. The less severe CKD was, the greater the visual improvement that could be achieved. In addition, relatively poor renal function required a lower anti-VEGF injection frequency. The active prevention of the progression of CKD may play a key role in DME treatment.

Paediatric cerebral palsy in South Africa: Prevention and care gaps at hospital level

Background: Population-based data show high proportions of severe cases of cerebral palsy (CP) in resource-poor regions such as sub-Saharan Africa, where most children have potentially preventable risk factors (factors that may increase the likelihood of CP occurrence but can be mitigated through medical interventions).Objectives: This study aimed to describe the demographic and clinical profile of children living with CP accessing services at Tygerberg Hospital over a period of 10 years (2010–2020), identify the potential gaps in care (proportion of individuals in a country requiring but not receiving suboptimal or inadequate care), and comparison with a similar study at the same centre two decades ago.Method: This 10-year retrospective study investigated causes and morbidities in children with CP, attending a central hospital in the Western Cape, South Africa.Results: A total of 613 children with CP were identified. Perinatal causes were predominant, especially in 57.7% (n = 354) of the cohort: perinatal asphyxia (41.1%) and preterm birth (16.6%). Postnatal causes constituted 15.2% (n = 93), which included tuberculous meningitis (3.6%) and bacterial meningitis (3.6%). The most common complications were intellectual impairment (61.8%; n = 379); epilepsy (30.8%; n = 189) and visual impairment (54.7%; n = 234). A third of the cohort had severe CP, classified as Gross Motor Function Classification System IV and V (38%).Conclusion: Most of the previously documented main drivers of CP are still present and the implementation of healthcare prevention strategies remains inadequate.Contribution: This study provides longitudinal evidence to confirm that CP in a South African setting is associated with a high burden of potentially preventable causes.

Emergency Medical Services and Police Utilization for Pediatric Mental and Behavioral Health Concerns Within a Large Hospital System.

This study aimed to compare emergency medical services (EMS) and police utilization trends, epidemiology, and emergency department (ED) outcomes between pediatric patients with mental or behavioral health (MBH) emergencies and those with non-MBH concerns transported to a large children's hospital system. This was a retrospective cohort study of patients aged 5 to 18 years transported via EMS and police to two EDs affiliated with a children's hospital from January 2012 through December 2020. Data were abstracted from electronic hospital records. Encounters for MBH emergencies were identified using diagnostic codes and chief complaints. Trends of EMS and police transports of patients with MBH emergencies were examined. Patient demographics and ED outcomes were compared between children presenting with MBH emergencies and those with non-MBH concerns. During the 9-year study period, out of 40,663 transports to the EDs, 36,137 (89%) arrived via EMS, and 4,526 (11%) arrived via police. A total of 10,250 (28.4%) EMS transports were for MBH emergencies. The volume of patients transported by EMS for MBH emergencies increased by 1.4% per year (P < 0.01) with no significant change in total EMS patient volumes. Patients with MBH emergencies transported by EMS were more likely to be older, female, of White race, and publicly insured; require restraint in the ED; and be admitted (P < 0.001). Of police transports, 4153 (91.8%) were for MBH emergencies, with no statistical change in the proportion of police transports that were for MBH emergencies. Police-transported MBH patients compared to non-MBH police-transported patients were more likely to be younger, female, and of White race (P < 0.001); 8.7% required mechanical/physical restraints in ED, 6.7% required pharmacologic restraint medications in ED, and 53% were admitted. The proportion of pediatric transports for MBH emergencies by EMS is rising and comprises the majority of police transports. Distinct from non-MBH pediatric patients transported, MBH patients necessitate significant ED resources, including ED-administered restraints and admission, highlighting their unique burden on the prehospital and ED systems.

Benefits and Safety of Empiric Antibiotic Treatment Active Against KPC-Producing Klebsiella pneumoniae for Febrile Neutropenic Episodes in Colonized Children with Acute Leukemia—An 8-Year Retrospective Observational Study

In children with acute leukemia (AL), the mortality rate from Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae bloodstream infection (KPC-KpBSI) exceeds 50%, highest when active treatment is delayed. Neutropenic KPC-K. pneumoniae carriers are at high risk of KPC-KpBSI, and preemptive empiric antibiotic treatment (EAT) of febrile neutropenic episodes (FNEs) active against KPC-K. pneumoniae may reduce this mortality. We conducted an 8-year (2014–2021) retrospective observational study of 112 febrile neutropenic episodes (FNEs) in 32 children with AL who were KPC-K. pneumoniae carriers: standard EAT for 39 FNEs and active EAT for 73 FNEs (52 ceftazidime/avibactam (CAZAVI)-based and 21 colistin-based combinations, and 5 CAZAVI monotherapy). Successful outcomes (survival from FNE) were observed in 94%; seven were fatal, with four due to infectious causes. KPC-KpBSIs caused 10/112 FNEs, 10/20 g-negative BSIs, and 3 deaths. The mortality rate of KPC-KpBSI was 30%. Active EAT was successful in 97% of the FNEs, compared to 87% with standard EAT. All deaths from KPC-KpBSI occurred in patients who received standard EAT, while none occurred with active EAT. KPC-KpBSI mortality rate with initial inactive treatment was 60%. CAZAVI-based EAT was successful in all FNEs, with a higher success rate without any modification compared to colistin-based EAT, where nephrotoxicity occurred in 14%. Therefore, active EAT, mainly a CAZAVI-based combination, was effective, safe, and associated with low overall and KPC-KpBSI-related mortality.

Ancestry and genome-wide association study of domestic pigs that survive African swine fever in Uganda

African swine fever (ASF) is endemic to Uganda and causes annual outbreaks. Some pigs survive these outbreaks and remain asymptomatic but are African swine fever virus (ASFV) positive. The potential heritability and genetic disparities in disease susceptibility among Ugandan pigs are not fully understood. In a 12-year study, whole blood and tissue samples were collected from 212 pigs across 19 districts in Uganda. Polymerase chain reaction (PCR) assays were used to determine ASFV infection status and genotyping was completed using a commercial porcine array. The point prevalence of ASF was calculated for each district, and breed composition origins were quantified for the sampled pigs by implementing established ancestry analyses. Genome-wide associated studies (GWAS) were conducted using all available domestic swine samples (full study population; n = 206) as well as a reduced dataset (farm-level study population; n = 129). This study revealed a greater number of ASFV-positive pigs in border districts than in non-border districts, a high level of admixture among domestic pigs sampled from Ugandan smallholder farms, and 48 loci that were associated with ASFV infection status. The discovery of 48 significant SNPs and 28 putative candidate genes may imply the possibility of heritability for resistance to ASFV. However, additional investigations in ASFV-endemic regions are required to fully elucidate the heritability of ASFV susceptibility among surviving pigs in Uganda.

Evaluation of stormwater runoff pollutant distributions combined with land-use information in a regional karst aquifer in Texas, USA.

Fast urbanization can result in significant stormwater runoff pollution due to changes in land use. A 3-year study on the distribution and temporal variations of urban water pollutants in stormwater runoff was conducted, with a specific focus on the influence of land-use patterns in the recharge zone of a regional karst aquifer in Texas (Edwards Aquifer). The presence and concentration of various water pollutants including total suspended solids (TSS), total dissolved solids (TDS), nutrients (nitrite, nitrate, ammonia and phosphate), total carbon (TC) and total organic carbon (TOC), oil and grease (O&G), and eight heavy metals (Fe, Mg, Cu, Pb, Zn, Ni, Cr, Cd) were measured in stormwater samples collected from three bioswales. Results show that average TSS in site S1 (598.87mg/L) and S2 (628.69mg/L), COD in site S1 (103.97mg/L), phosphate in sites S1 (1.44mg/L) and S3 (0.65mg/L), and O&G (ranging from 50.63 to 84.32mg/L) in all three sites surpassed the national average (NSQD). While residential areas were identified as the main sources of nutrients, roads and parking lots were associated with heavy metals. Temporal variations indicated the effect of antecedent dry days on the concentrations of TSS and phosphate. Growing seasons as well as pet feces were associated with elevated nitrate concentrations in residential areas. Organic carbon was found overall higher during warmer months, while heavy metals during cooler months. The study also identified specific land-use practices that can be enhanced to mitigate stormwater pollution, such as the implementation of permeable pavements, rain gardens, and stricter waste disposal regulations. The results of this study offer valuable insights for enhancing stormwater management strategies to better mitigate stormwater pollution in urban regions.
