Introduction: Fingermarks left at a crime scene can indicate the presence of an individual and his/her involvement in the crime. Fingermarks, usually invisible, can appear on any surface and may be contaminated by any exogenous substances, including drug substance. Recovery of fingermarks contaminated by drug substance is crucial to link an individual with the drug-related crimes. Hence, this study was aimed to investigate the recovery and visualisation of methamphetamine-contaminated fingermarks from various non-porous surface materials. Methods: In this study, fingermarks were deposited on 11 types of surface materials varied by the presence of methamphetamine contamination, immediacy of deposition, and their concentration levels. Each fingermark was then developed using white and black fingerprint powders, graded, and compared based on the different settings. Results: Application of fingerprint powder was good in developing fingermarks; however, its suitability depends on the nature of the surface materials. Black fingerprint powder produced better visualisation where the fingermarks on all the 11 surface materials tested in this study were successfully recovered compared to white fingerprint powders. Methamphetamine-contaminated fingermarks could still be recovered using the fingerprint powder dusting method, but the fingermark grade was reduced due to the presence of exogenous substance. Conclusion: To conclude, the recovery and visualisation of methamphetamine-contaminated fingermarks on non-porous surfaces were successfully carried out through the application of fingerprint powder. A more severe contamination might lead to lower fingermark grade showing lesser ridge details.

Introduction: There are few limited studies on the rate of suicidal thoughts and attempts between students in the Middle East, especially in Saudi Arabia. Aim: We sought to assess the rate of suicide ideation and attempts between students at King Abdulaziz University in Jeddah, Saudi Arabia Materials and Methods: We conducted a cross-sectional study between 2019 and 2022, with 3,514 participants aged between 17 and 25 years. Data were obtained using an electroni questionnaire based on the Depression, Anxiety, and Stress Scale-21. All statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) version 21. Results and Discussion: Of the 3,514 students who completed the questionnaire, 1,324 were male and 2,190 were female; 8.4% had attempted suicide in the past year, and 23.4% had thought of suicide in the past year. We noted a strong relationship between depression level and suicidal thoughts. Over 68 respondents had been diagnosed with severe depression, and 58.8% had attempted suicide in the past year. Suicidal thoughts and attempts were also strongly related to anxiety; 246 students had been diagnosed with anxiety in the previous year. Conclusion: One of the leading reasons of mortality among adolescents is suicide. Early follow-up can enhance mental health and quality of life.

Objective: This study is a preliminary work to develop a Malay version questionnaire named ‘Inventori Persepsi bagi Muslim yang Memiliki Masalah Pendengaran (IPM3P)’ to assess the perception on Islamic understanding and practice among Muslim adults with hearing impairment. Methods: The scale development involved three phases: i) generation of domains based on the literature, ii) generation of sub-domains based on literature review and Islamic panel survey, and iii) generation of items. Results: Preliminary version of IPM3P consists of 59 items was produced, representing three domains: Obligation (18 items), Practice (21 items), and Difficulty (20 items), and seven sub-domains (‘Ibadah’, ‘Aqidah’, ‘Muamalat’, ‘Tasawwuf’, ‘Akhlak’,‘Da’wah’, and ‘Sirah’). Conclusion: The preliminary version of IPM3P needs to be psychometrically tested. This pioneering study may become an impetus towards more research pertaining to understanding the effect of hearing loss towards religious life in the future in Malaysia.

Objective: To study the chemical profile, antimicrobial properties, and synergistic effect with known antibiotics of essential oil extracted from the marine red macroalgae Centroceras clavulatum (C. Agardh) Montagne, collected in Morocco. Methods: The chemical composition of the oil was analyzed by gas chromatography-mass spectrometry. The oil was evaluated for antibacterial (Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis, Micrococcus luteus, Staphylococcus aureus, and Klebsiella pneumoniae), and antifungal activity (Candida albicans, Candida glabrata, Candida krusei, and Candida parapsilosis), by the disc diffusion method. The minimum inhibitory and minimum microbicidal concentrations of the oil were determined, as well as the synergistic effects of its application combined with the antibiotics ciprofloxacin and fluconazole, by the checkerboard method. Results: Thirty molecules were identified in the essential oil, comprising 96.27% of the total oil composition. Monoterpenes such as carvacrol (36.06%) were the most abundant compounds, followed by caryophyllene (14.67%), endo-borneol (9.04%), pyroterebic acid (3.23%) and caryophyllene oxide (3.13%). The oil exhibited a moderate antimicrobial activity with inhibition zone diameters ranging from 9.0 to 15.0 mm. The minimum inhibitory concentration values varied between 0.9 and 14.7 mg/mL, and Bacillus subtilis and Escherichia coli were the more sensitive bacteria with 0.9 and 1.9 mg/mL, respectively. The minimum microbicidal concentration values ranged from 0.4 to 14.7 mg/mL. A significant synergic action was observed when the oil was applied in combination with ciprofloxacin and fluconazole, with fractional inhibitory concentration index values ranging from 0.31 to 0.50. Synergy was found in 80% of the combinations and a 2 to 16-fold reduction of antibiotics MIC was observed. Conclusions: Our findings suggest that the essential oil of Centroceras clavulatum should be further appraised for its potential use in the management of multi-drug resistant microorganisms, with the purpose to restore the activity of standard antimicrobial drugs.
