1. Occurrence of twelve UV filters and evidence of cis-octinoxate formation in Adriatic coastal waters: Environmental implications.
Field monitoring along the Adriatic coast identified twelve UV filters in coastal waters and provided evidence that octinoxate can convert to its cis-isomer in situ. These findings underscore the environmental persistence and transformation of sunscreen agents, informing risk assessment and potential regulatory actions.
Impact: Demonstrating in situ formation of cis-octinoxate elevates concern beyond mere occurrence, pointing to transformation pathways that may alter toxicity and persistence. This evidence can shape sunscreen formulation choices and environmental policy.
Clinical Implications: Dermatology and primary care can incorporate environmental counseling (e.g., reef-safer filters) when advising on sunscreen selection, balancing photoprotection with eco-impact. Public health messaging may adapt based on transformation risks.
Key Findings
- Twelve UV filters were detected in Adriatic coastal waters.
- Evidence supports in situ formation of cis-octinoxate in natural waters.
- Findings highlight persistence and ecological risk considerations for personal care UV filters.
Methodological Strengths
- Multi-analyte environmental monitoring targeting a broad set of UV filters
- Field-based evidence of transformation (cis-isomer formation)
Limitations
- Temporal and spatial coverage likely limited to specific coastal segments and periods
- Mechanistic pathways and kinetics of isomerization not fully resolved in situ
Future Directions: Expand longitudinal and seasonal monitoring, quantify isomer-specific toxicity, and evaluate formulation alternatives with lower environmental persistence.
UV filters used in personal care products are increasingly recognised as emerging contaminants due to their persistence and ecological risks. Detected in aquatic systems at concentrations from ng L
2. Polyimide nanosheets based magnetic solid-phase extraction for the extraction of parabens from cosmetic samples followed by gas chromatography-mass spectrometry.
The authors present a magnetic solid-phase extraction platform using polyimide nanosheet-based composites to isolate parabens from cosmetic matrices, coupled with GC-MS for quantification. This method streamlines sample preparation and enhances selectivity, facilitating routine surveillance of preservative residues.
Impact: A new sorbent architecture and magnetic workflow can notably reduce analytical burden in quality control labs, enabling broader monitoring of cosmetic preservatives.
Clinical Implications: While not a clinical test, improved detection of parabens supports regulatory compliance and consumer safety, informing dermatologists when evaluating contact allergy histories to preservatives.
Key Findings
- Developed a polyimide nanosheet-based magnetic sorbent for solid-phase extraction of parabens from cosmetic samples.
- Coupled magnetic SPE with GC-MS for downstream identification and quantification.
- Workflow aims to improve extraction efficiency and selectivity, simplifying sample preparation.
Methodological Strengths
- Innovative sorbent material design leveraging high-surface-area nanosheets
- Magnetic separation simplifies handling and reduces processing time before GC-MS
Limitations
- Performance across diverse cosmetic matrices and inter-laboratory reproducibility need broader validation
- Potential matrix effects and carryover not fully characterized in the abstract
Future Directions: Validate the method across multiple labs and product types, extend to additional preservatives and UV filters, and integrate automation for high-throughput screening.
This study introduces a novel magnetic composite based on polyimide nanosheets (Fe
3. Perspectives on managing skin manifestations in cancer patients: a multidisciplinary mixed-method survey of oncologists and dermatologists.
A mixed-method survey of 117 dermatologists and 19 oncologists in the Middle East found divergent exposure and comfort levels in managing cancer treatment-related skin toxicities. Oncologists encountered cases more frequently but reported lower confidence; barriers included selecting dermo-cosmetic products and limited oncodermatology knowledge, emphasizing the need for structured collaboration.
Impact: By quantifying specialty-specific gaps and barriers, the study provides concrete targets for oncodermatology education, referral pathways, and supportive care protocols across a region with limited prior data.
Clinical Implications: Implement co-managed care models with early dermatology referral, standardized algorithms for common toxicities (e.g., hand-foot syndrome, nail changes), and curated dermo-cosmetic formularies to minimize treatment interruptions.
Key Findings
- Oncologists reported daily encounters with skin manifestations more often than dermatologists (44.4% vs. 8.1%, p<0.001).
- Nail changes were more frequently reported by dermatologists (72.6% vs. 31.6%, p<0.001), while hand-foot syndrome was more common for oncologists (89.5% vs. 6.0%, p<0.001).
- Dermatologists were more comfortable managing toxicities (50.4% vs. 10.5%, p=0.004); barriers included severity, dermo-cosmetic product selection, and limited oncodermatology knowledge.
Methodological Strengths
- Mixed-methods design integrating quantitative and qualitative data
- Inclusion of two key specialties enables comparative insights
Limitations
- Convenience sampling at a medical convention may introduce selection bias
- Small oncologist sample size and self-reported practices limit generalizability
Future Directions: Develop regional consensus guidelines, implement joint clinics or e-consults, and evaluate training interventions that improve early recognition and management of skin toxicities.
BACKGROUND: Cancer treatments often cause skin toxicities that disrupt therapy and reduce patients' quality of life, yet research on their management in the Middle East is scarce. This study aims to examine the practices and challenges of managing skin-related adverse effects in cancer patients. METHODS: A mixed-method survey was conducted on a sample of dermatologists and oncologists practicing in Middle Eastern countries who were invited to participate in Pierre Fabre's annual Middle East Medical Convention. A brief online questionnaire, distributed to 250 dermatologists and 19 oncologists, using both quantitative and qualitative approaches, assessed the frequency, types, and management of skin conditions, alongside perceived barriers and referral practices. RESULTS: The study included responses from 117 dermatologists and 19 oncologists. Oncologists encountered cancer-related skin manifestations considerably more often, with 44.4% seeing such cases daily compared to 8.1% of dermatologists (p < 0.001). Notable differences were also observed in the types of skin conditions reported, such as nail changes, which were significantly more frequent among dermatologists (72.6% vs. 31.6%, p < 0.001), whereas hand-foot syndrome was markedly more commonly observed among oncologists (89.5% vs. 6.0%, p < 0.001). Dermatologists reported feeling very comfortable managing these conditions more often than oncologists (50.4% vs. 10.5%, p = 0.004). Key barriers included the severity of skin conditions, selecting appropriate dermo-cosmetic products, and limited knowledge in onco-dermatology. The qualitative analysis highlighted oncologists' challenges in managing skin toxicities under three main themes: (1) preventing cancer treatment interruptions, (2) limited specialized dermatologic knowledge and support, and (3) addressing patient-centered issues. CONCLUSION: Findings reveal differing perspectives between dermatologists and oncologists and underscore the need for greater collaboration to optimize the management of cancer-related skin toxicities.
