  1. Maqasid al-shariah as a complementary framework to conventional bioethics
    Saifuddeen SM, Rahman NN, Isa NM, Baharuddin A
    Sci Eng Ethics, 2014 Jun;20(2):317-27.
    PMID: 23836155 DOI: 10.1007/s11948-013-9457-0
    With the rapid advancements made in biotechnology, bioethical discourse has become increasingly important. Bioethics is a multidisciplinary and interdisciplinary field that goes beyond the realm of natural sciences, and has involved fields in the domain of the social sciences. One of the important areas in bioethical discourse is religion. In a country like Malaysia, where Muslims make up the majority of the population, Islam plays a crucial role in providing the essential guidelines on the permissibility and acceptability of biotechnological applications in various fields such as medicine, agriculture, and food processing. This article looks at the framework of a complementary model of bioethics derived from the perspective of Islam. The framework is based on 'maqasid al-shariah' (purposes or objectives of Islamic law) which aims to protect and preserve mankind's faith, life, intellect, progeny, and property. It is proposed that 'maqasid al-shariah' be used as a pragmatic checklist that can be utilized in tackling bioethical issues and dilemmas.
  2. The Right to Use Kratom from the Psychiatric and Islamic Perspectives
    Leong Bin Abdullah MFI, Mohamad MA, Abdul Rahman NN
    J Relig Health, 2021 Apr;60(2):841-853.
    PMID: 31069602 DOI: 10.1007/s10943-019-00830-w
    This paper aimed to summarize kratom's psychological effects on users and the Islamic views on kratom use. A literature survey of published kratom studies, teachings based on the holy Qur'an, the Sunnah, and views of several Islamic scholars based on qualitative methodology through text analysis was conducted. The results demonstrated that despite its beneficial therapeutic effects, the harm induced by kratom outweighs its benefits. We concluded that kratom use for medicinal purposes is only warranted if useful constituent mitragynine can be extracted and used on its own, and if more rigorous human studies demonstrated good safety profile and efficacy of mitragynine for therapeutic purposes.
  3. Fulltext Correlation between thoracolumbar curvatures and respiratory function in older adults
    Rahman NN, Singh DK, Lee R
    Clin Interv Aging, 2017;12:523-529.
    PMID: 28352165 DOI: 10.2147/CIA.S110329
    Aging is associated with alterations in thoracolumbar curvatures and respiratory function. Research information regarding the correlation between thoracolumbar curvatures and a comprehensive examination of respiratory function parameters in older adults is limited. The aim of the present study was to examine the correlation between thoracolumbar curvatures and respiratory function in community-dwelling older adults. Thoracolumbar curvatures (thoracic and lumbar) were measured using a motion tracker. Respiratory function parameters such as lung function, respiratory rate, respiratory muscle strength and respiratory muscle thickness (diaphragm and intercostal) were measured using a spirometer, triaxial accelerometer, respiratory pressure meter and ultrasound imaging, respectively. Sixty-eight community-dwelling older males and females from Kuala Lumpur, Malaysia, with mean (standard deviation) age of 66.63 (5.16) years participated in this cross-sectional study. The results showed that mean (standard deviation) thoracic curvature angle and lumbar curvature angles were -46.30° (14.66°) and 14.10° (10.58°), respectively. There was a significant negative correlation between thoracic curvature angle and lung function (forced expiratory volume in 1 second: r=-0.23, P<0.05; forced vital capacity: r=-0.32, P<0.05), quiet expiration intercostal thickness (r=-0.22, P<0.05) and deep expiration diaphragm muscle thickness (r=-0.21, P<0.05). The lumbar curvature angle had a significant negative correlation with respiratory muscle strength (r=-0.29, P<0.05) and diaphragm muscle thickness at deep inspiration (r=-0.22, P<0.05). However, respiratory rate was correlated neither with thoracic nor with lumbar curvatures. The findings of this study suggest that increase in both thoracic and lumbar curvatures is correlated with decrease in respiratory muscle strength, respiratory muscle thickness and some parameters of lung function. Clinically, both thoracic and lumbar curvatures, respiratory muscles and lung function should be taken into consideration in the holistic management of respiratory function among older adults.
  4. Islamic Considerations on the Application of Patient's Autonomy in End-of-Life Decision
    Malek MM, Abdul Rahman NN, Hasan MS, Haji Abdullah L
    J Relig Health, 2018 Aug;57(4):1524-1537.
    PMID: 29417395 DOI: 10.1007/s10943-018-0575-5
    In end-of-life situation, the need for patient's preference comes into the picture with the intention of guiding physicians in the direction of patient care. Preference in medical directive is made by a person with full mental capacity outlining what actions should be taken for his health should he loses his competency. This is based on the reality of universal paradigm in medical practice that emphasises patient's autonomy. A specific directive is produced according to a patient's wish that might include some ethically and religiously controversial directives such as mercy killing, physician-assisted suicide, forgoing life-supporting treatments and do-not-resuscitate. In the future, patient autonomy is expected to become prevalent. The extent of patient autonomy has not been widely discussed among Muslim scholars. In Islam, there are certain considerations that must be adhered to.
  5. Fulltext Three-Dimensional (3D) Printing of Organs according to the Perspective of Islamic Law
    Sabri AM, Ramli MA, Abdul Rahman NN, Hamdan MN
    Asian Bioeth Rev, 2023 Jan;15(1):69-80.
    PMID: 36618954 DOI: 10.1007/s41649-022-00210-9
    The outburst of the fourth Industrial Revolution had a significant impact on many aspects of life. The discovery of new technologies in medicine has resulted in innovations: organ transplants. The introduction of three-dimensional (3D) organ printing technology promises improvements to the field. Organs such as the liver, kidneys, heart and others are printed to meet the needs of the actual organs. However, the production of prototype organs to replace the original organs is associated with the issue of changing the creation of Allah. Accordingly, this study will analyse the issue of changing the creation of God in three-dimensional (3D) organ printing technology according to the perspective of Islamic law. Several appropriate methodologies in Islamic law (usul fiqh) are used such as legal reasoning through maqasid shariah perspective and analogical reasoning. The result shows that three-dimensional (3D) organ printing technology falls under the permissible category of changing the creation of Allah because it can save human lives. The production of organs through 3D printing involving changes included in the category of necessity (daruri) and need (hajiy) is permissible, but the category of desirable (tahsini) requires further specifications.
  6. Optimizing supercritical carbon dioxide in the inactivation of bacteria in clinical solid waste by using response surface methodology
    Hossain MS, Nik Ab Rahman NN, Balakrishnan V, Alkarkhi AF, Ahmad Rajion Z, Ab Kadir MO
    Waste Manag, 2015 Apr;38:462-73.
    PMID: 25636860 DOI: 10.1016/j.wasman.2015.01.003
    Clinical solid waste (CSW) poses a challenge to health care facilities because of the presence of pathogenic microorganisms, leading to concerns in the effective sterilization of the CSW for safe handling and elimination of infectious disease transmission. In the present study, supercritical carbon dioxide (SC-CO2) was applied to inactivate gram-positive Staphylococcus aureus, Enterococcus faecalis, Bacillus subtilis, and gram-negative Escherichia coli in CSW. The effects of SC-CO2 sterilization parameters such as pressure, temperature, and time were investigated and optimized by response surface methodology (RSM). Results showed that the data were adequately fitted into the second-order polynomial model. The linear quadratic terms and interaction between pressure and temperature had significant effects on the inactivation of S. aureus, E. coli, E. faecalis, and B. subtilis in CSW. Optimum conditions for the complete inactivation of bacteria within the experimental range of the studied variables were 20 MPa, 60 °C, and 60 min. The SC-CO2-treated bacterial cells, observed under a scanning electron microscope, showed morphological changes, including cell breakage and dislodged cell walls, which could have caused the inactivation. This espouses the inference that SC-CO2 exerts strong inactivating effects on the bacteria present in CSW, and has the potential to be used in CSW management for the safe handling and recycling-reuse of CSW materials.
  7. Fulltext Treatment of clinical solid waste using a steam autoclave as a possible alternative technology to incineration
    Hossain MS, Balakrishnan V, Rahman NN, Sarker MZ, Kadir MO
    Int J Environ Res Public Health, 2012 Mar;9(3):855-67.
    PMID: 22690168 DOI: 10.3390/ijerph9030855
    A steam autoclave was used to sterilize bacteria in clinical solid waste in order to determine an alternative to incineration technology in clinical solid waste management. The influence of contact time (0, 5, 15, 30 and 60 min) and temperature (111 °C, 121 °C and 131 °C) at automated saturated steam pressure was investigated. Results showed that with increasing contact time and temperature, the number of surviving bacteria decreased. The optimum experimental conditions as measured by degree of inactivation of bacteria were 121 °C for 15 minutes (min) for Gram negative bacteria, 121 °C and 131 °C for 60 and 30 min for Gram positive bacteria, respectively. The re-growth of bacteria in sterilized waste was also evaluated in the present study. It was found that bacterial re-growth started two days after the inactivation. The present study recommends that the steam autoclave cannot be considered as an alternative technology to incineration in clinical solid waste management.

    Teh TL, Rahman NN, Shahadat M, Wong YS, Syakir MI, Omar AK
    Environ Monit Assess, 2016 Jul;188(7):404.
    PMID: 27295186 DOI: 10.1007/s10661-016-5394-0
    The present study deals with possible contamination of the soil by metal ions which have been affecting the environment. The concentrations of metal ions in 14 borehole samples were studied using the ICP-OES standard method. The degree of contamination was determined on the basis of single element pollution index (SEPI), combined pollution index (CPI), soil enrichment factor (SEF), and geo-accumulation index (Igeo). Geo-accumulation indices and contamination factors indicated moderate to strong contaminations for eight boreholes (BL-1, BL-2, BL-6, BL-8, BL-9, BL-10, BL-12, and BL-13) while the rest were extremely contaminated. Among all the boreholes, BL-3 and BL-11 demonstrated the highest level of Cd(II) and Pb(II) which were found the most polluted sites. The level of metal contamination was also compared with other countries. The development, variation, and limitations regarding the regulations of soil and groundwater contamination can be provided as a helpful guidance for the risk assessment of metal ions in developing countries.
  9. The right of women in property sharing in Bangladesh: Can the islamic inheritance system eliminate discrimination?
    Khan I, Abdullah MF, Rahman NN, Nor MR, Yusoff MY
    Springerplus, 2016;5(1):1695.
    PMID: 27757367
    This study seeks to discover the best solution for women's property sharing between Islamic and current social practices in Bangladesh. A qualitative method has been adopted to achieve this goal. It is found that the majority of the women are marginalised from their property in the social practice. On the other hand, in the Islamic solution, the property is fixed for all classes of women and is based on a property sharing system called fara'id that takes into account the roles and responsibilities of man and woman in the society. Men are responsible for providing maintenance to their wives and children. Men in Islamic society should bear expenditure related to marriage. The research concludes that the Islamic solution is fair and ensures just property sharing rights for women. It suggests that the Islamic solution for property sharing should be implemented to empower women in Bangladesh.
  10. Fulltext History, problems, and prospects of Islamic insurance (Takaful) in Bangladesh
    Khan I, Rahman NN, Yusoff MY, Nor MR
    Springerplus, 2016;5(1):785.
    PMID: 27386271 DOI: 10.1186/s40064-016-2400-5
    This study explains the history, current problems, and future possibilities of Islamic insurance (takaful) in Bangladesh. To articulate these issues, the researcher has adopted the qualitative method, and data has been collected through secondary sources i.e. articles, books, and online resources. The study reveals that Islamic insurance in Bangladesh is regulated by the Insurance Act 2010 which is contradictory with Islamic insurance causing numerous problems for Islamic insurance. This study also points out that Islamic insurance is a fast growing industry with huge prospects in Bangladesh. The government should introduce separate regulations for both Islamic and conventional insurance. The research concludes with suggestions for the further development of Islamic insurance in Bangladesh.

    Noman EA, Al-Gheethi AA, Rahman NN, Nagao H, Ab Kadir MO
    Environ Sci Pollut Res Int, 2016 Oct;23(19):19806-24.
    PMID: 27417327 DOI: 10.1007/s11356-016-7161-8
    The study aimed to determine the fungal diversity in clinical waste samples from a healthcare facility in Penang Malaysia. Different fungi species were detected in 83.75 % of the 92 clinical waste samples that were screened from different sections of the healthcare facility. One hundred fifty fungal isolates comprising of 8 genera and 36 species were obtained. They were purified by using single spore isolation technique. Subsequently, the isolates were identified by phenotypic method based on morphological and culture characteristics on different culture media. Among all fungal isolates, Aspergillus spp. in section Nigri 10.2 %, Aspergillus niger 9.5 %, Aspergillus fumigatus 8.8 %, Penicillium. simplicissium 8 %, Aspergillus tubingensis 7.3 %, Aspergillus terreus var. terreus 6.6 %, Penicillium waksmanii 5.9 % and Curvularia lunata 6.5 % were the most frequent. Among five sections of the Wellness Centre, the clinical wastes collected from the diagnostic labs of haematology section had the highest numbers of fungal species (29 species). Glove wastes had the highest numbers of fungal species (19 species) among 17 types of clinical wastes screened. Among all fungal species, Aspergillus spp. exhibited higher growth at 37 °C than at 28 °C, indicating the potential of these opportunistic fungi to cause diseases in human. These results indicated the potential of hospital wastes as reservoirs for fungal species.
  12. Fulltext Infectious risk assessment of unsafe handling practices and management of clinical solid waste
    Hossain MS, Rahman NN, Balakrishnan V, Puvanesuaran VR, Sarker MZ, Kadir MO
    Int J Environ Res Public Health, 2013 Jan 31;10(2):556-67.
    PMID: 23435587 DOI: 10.3390/ijerph10020556
    The present study was undertaken to determine the bacterial agents present in various clinical solid wastes, general waste and clinical sharp waste. The waste was collected from different wards/units in a healthcare facility in Penang Island, Malaysia. The presence of bacterial agents in clinical and general waste was determined using the conventional bacteria identification methods. Several pathogenic bacteria including opportunistic bacterial agent such as Pseudomonas aeruginosa, Salmonella spp., Klebsiella pneumoniae, Serratia marcescens, Acinetobacter baumannii, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus pyogenes were detected in clinical solid wastes. The presence of specific pathogenic bacterial strains in clinical sharp waste was determined using 16s rDNA analysis. In this study, several nosocomial pathogenic bacteria strains of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Lysinibacillus sphaericus, Serratia marcescens, and Staphylococcus aureus were detected in clinical sharp waste. The present study suggests that waste generated from healthcare facilities should be sterilized at the point of generation in order to eliminate nosocomial infections from the general waste or either of the clinical wastes.

    Microplastics (MPs) are a pervasive pollutant in the marine environment. Pantai Teluk Likas in Sabah, Malaysia is one of the most visited beaches where tourism, recreational, and fisheries activities are high in this area. Hence, the area suffers from severe pollution, particularly from plastics. This study aims to quantify the microplastic composition in terms of color, shapes, and polymer types in marine bivalves (Anadara granosa, Glauconome virens, and Meretrix lyrata) and water column samples from Pantai Teluk Likas. All samples were digested using sodium hydroxide (NaOH) and incubated in the oven for at least 48 h. Serial filtration was done for each sample before they were observed under the dissecting microscope. The microplastics were identified and counted based on their physical attributes which were colors and shapes. The functional group of the polymers was determined using FTIR spectroscopy. Microplastics were found present in all samples collected. G. virens had the highest abundance of microplastics at 113.6 ± 6.5 particles/g followed by M. lyrata at 78.4 ± 3.7 particles/g. On the contrary, A. granosa had the least microplastics with an abundance of 24.4 ± 0.6 particles/g. Meanwhile, 110.0 ± 36.2 particles/L of microplastics were found in water column samples from Pantai Teluk Likas. Based on the analysis, fibers were the most common shape in bivalves, while fibers and films were common in the water column. In terms of colors, black, blue, and red were a few of the most abundant colors observed in both samples. The most common polymer detected in all bivalve species and water column samples is polycarbonate (PC), followed by polymethyl methacrylate (PMMA). Future study that focuses on the correlation between microplastic abundance in the marine biota and the water column is recommended to better understand microplastic availability and exposure.
  14. Honouring Wishes of Patients: An Islamic View on the Implementation of the Advance Medical Directive in Malaysia
    Malek MM, Saifuddeen SM, Abdul Rahman NN, Yusof ANM, Abdul Majid WR
    Malays J Med Sci, 2021 Apr;28(2):28-38.
    PMID: 33958958 DOI: 10.21315/mjms2021.28.2.3
    An Advance Medical Directive (AMD) is a document in which competent patients express their wishes regarding their preferred choice of future medical plans in the event they become incompetent. AMD is important in relation to the patient's right to refuse treatment. However, they must also consider cultural and religious values of different communities. In Islam, there are several concerns that need to be addressed, namely the validity of the AMD according to Islamic jurisprudence and patients' right to end-of-life decision-making. To address these concerns, this article refers to multiple sources of Islamic jurisprudence, such as the Quran, the tradition of Prophet Muhammad and the works of Islamic scholars related to this topic. Based on the findings, Islam does not forbid the use of AMD as a method to honour patients' wishes in their end-of-life care. Islamic jurisprudence emphasises on the importance of seeking patients' consent before carrying out any medical procedures. However, several conditions need to be given due attention, such as: i) a patient's cognitive capacity during the process of drawing up an AMD; ii) the professional views of medical experts; iii) the involvement of family members in end-of-life care and iv) the limitations of a patient's decision-making in creating an AMD.
  15. Fulltext Applications of supercritical fluid extraction (SFE) of palm oil and oil from natural sources
    Akanda MJ, Sarker MZ, Ferdosh S, Manap MY, Ab Rahman NN, Ab Kadir MO
    Molecules, 2012 Feb 10;17(2):1764-94.
    PMID: 22328076 DOI: 10.3390/molecules17021764
    Supercritical fluid extraction (SFE), which has received much interest in its use and further development for industrial applications, is a method that offers some advantages over conventional methods, especially for the palm oil industry. SC-CO₂ refers to supercritical fluid extraction (SFE) that uses carbon dioxide (CO₂) as a solvent which is a nontoxic, inexpensive, nonflammable, and nonpolluting supercritical fluid solvent for the extraction of natural products. Almost 100% oil can be extracted and it is regarded as safe, with organic solvent-free extracts having superior organoleptic profiles. The palm oil industry is one of the major industries in Malaysia that provides a major contribution to the national income. Malaysia is the second largest palm oil and palm kernel oil producer in the World. This paper reviews advances in applications of supercritical carbon dioxide (SC-CO₂) extraction of oils from natural sources, in particular palm oil, minor constituents in palm oil, producing fractionated, refined, bleached, and deodorized palm oil, palm kernel oil and purified fatty acid fractions commendable for downstream uses as in toiletries and confectionaries.
  16. Senile Dementia from Neuroscientific and Islamic Perspectives
    Tumiran MA, Abdul Rahman NN, Mohd Saat R, Ismail AZ, Ruzali WAW, Bashar NKN, et al.
    J Relig Health, 2018 Feb;57(1):1-11.
    PMID: 26160145 DOI: 10.1007/s10943-015-0079-5
    Diseases involving the nervous system drastically change lives of victims and commonly increase dependency on others. This paper focuses on senile dementia from both the neuroscientific and Islamic perspectives, with special emphasis on the integration of ideas between the two different disciplines. This would enable effective implementation of strategies to address issues involving this disease across different cultures, especially among the world-wide Muslim communities. In addition, certain incongruence ideas on similar issues can be understood better. The former perspective is molded according to conventional modern science, while the latter on the analysis of various texts including the holy Qur'an, sunnah [sayings and actions of the Islamic prophet, Muhammad (pbuh)] and writings of Islamic scholars. Emphasis is particularly given on causes, symptoms, treatments and prevention of dementia.
  17. Lactobacillus probiotics restore vaginal and gut microbiota of pregnant women with vaginal candidiasis
    Ang XY, Roslan NS, Ahmad N, Yusof SM, Abdullah N, Nik Ab Rahman NN, et al.
    Benef Microbes, 2023 Nov 23;14(5):421-431.
    PMID: 38350486 DOI: 10.1163/18762891-20220103
    The development of probiotics has now included the areas along the gut-vaginal axis. We thus aimed to investigate the effects of lactobacilli probiotic to modulate and restore vaginal and gut microbiota of pregnant women with vaginal candidiasis (VC). A randomised, double-blind and placebo-controlled study was performed in 78 pregnant women with VC. Patients were randomised to either the probiotic (SynForU-HerCare) or placebo which were administered at baseline and continued for 8-weeks (two capsules/day of 9.5 log cfu/capsule). Microbiota profiles were assessed at time points of weeks-0, 4 and 8 for high vaginal swab and faecal samples. Shannon diversity index showed that after 8-weeks amid VC, a shift in microbial community compositional changes occurred in the high vaginal region at both genus (P=0.025) and species (P=0.044) levels, where the administration of probiotic prevented such a shift. These changes were mainly attributed to a decreased in abundance of Lactobacillus (P=0.042) accompanied by increased abundance of Prevotella (P=0.002) and Atopobium (P=0.002) in the placebo group while the probiotic group remained unchanged over time. The administration of probiotics also prevented a reduced abundance of faecal phylum Firmicutes after 8-weeks as seen in the placebo group (P<0.0001), which also showed reduction at subsequent taxonomic levels of class, family, genera and species. VC has not only altered the microbiota of vagina regions but also gut microbiota profiles, causing lessening of gut microbiota that are crucial for gut nutrient availability, protection and immunity. The administration of lactobacilli probiotics has prevented such a shift, leading to better modulated gut and vaginal microenvironment amid VC. The study was registered at ClinicalTrials.gov: identifier number NCT03940612.
  18. Lactobacilli reduce recurrences of vaginal candidiasis in pregnant women: a randomized, double-blind, placebo-controlled study
    Ang XY, Chung FY, Lee BK, Azhar SNA, Sany S, Roslan NS, et al.
    J Appl Microbiol, 2021 May 22.
    PMID: 34022103 DOI: 10.1111/jam.15158
    AIMS: The aim of this study was to investigate the effects of lactobacilli strains in preventing the recurrences of vaginal candidiasis (VC) in 78 pregnant women with VC (lactobacilli, n = 39; placebo, n = 39) and the potential benefits on quality of life.

    METHODS AND RESULTS: The lactobacilli putative probiotic (SynForU-HerCare; two capsules/day of 9·5 log CFU per capsule) or placebo was administered for 8-weeks in a randomized, double-blind, placebo-controlled study. Subjects were assessed for vaginal and gut health conditions at baseline, week-4 and week-8 via questionnaires. The vulvovaginal symptom questionnaire not only covered aspects pertaining to vulvovaginal symptoms but also the quality of life impacts such as emotional, social and sexual. The administration of lactobacilli reduced symptoms of irritation (P = 0·023) and discharge (P = 0·011) starting week-4 and continued after week-8 (P
