Nouri AI, Hassali MA, Hashmi FK

Perspect Public Health, 2020 Jan;140(1):62-66.
PMID: 31165671 DOI: 10.1177/1757913919832927

AIMS: This article examines the outputs of pharmaceutical education with the development of the pharmacy profession and how that affects pharmaceutical innovation. It also discusses different models of collaboration between the academic and pharmaceutical industry in order to achieve a healthy collaboration between the stakeholders.
METHODS: The perspective, experiences and insights of educators from various backgrounds, origin and educational levels were sought regarding the role of pharmacy education in providing pharmaceutical research and development workforce.
RESULTS: Many countries around the world are currently undertaking major reforms in pharmacy education due to the changing landscape of health and healthcare delivery. These reforms must be accompanied by robust systems to assure that the quality of educational structures, processes and outcomes will produce competent pharmacy graduates in the future. It is also considered imperative that pharmacy academic institutions should establish collaboration with the drug development units, the pharmaceutical industry and government agencies for sustainability and positive research outcomes.
CONCLUSION: Shortcomings in pharmacy curricula need to be addressed and the authors have proposed the 'TARGET' approach for the development of integrated pharmacy curriculum to substantially contribute to pharmaceutical research and development.

Sugar molasses from agricultural waste could be a sustainable carbon source for the synthesis of graphene adsorbent introduced in this work. The sugar molasses was successfully converted to graphene-like material and subsequently coated on the sand as graphene sand composite (GSC), as proven by XRD, XPS, Raman spectroscopy, and SEM with EDX mapping analyses. The adsorption performance of GSC was evaluated against the removal of Tetracycline (TC) and methylene blue (MB) pollutants from an aqueous solution in a fixed bed column continuous-flow adsorption setup. The effect of different process conditions: bed height (4-12 cm), influent flow rate (3-7 mL/min), and contaminants' concentration (50-150 ppm) was investigated. The results revealed that column performance was improved by increasing the bed depth and lowering the flow rate and concentration of the pollutants. The best removal efficiency was obtained when the bed height was 12 cm, the influent flow rate of 3 mL/min, and the pollutants' initial concentration was 50 mg/L. Thomas, Adams-Bohart, and Yoon-Nelson models were attempted to fit the breakthrough curves. Regeneration of the GSC indicated the decline of breakthrough time from 240-280 to 180 min, reflecting the decrease in adsorptive sites due to the incomplete regeneration process. Overall, sugar molasses was shown to be a low-cost precursor for synthesizing valuable graphene material in the form of GSC, which can reduce the problem for industrial waste management of sugar molasses, and the GSC could be used as an adsorbent for environmental application.
Fulltext Sustainable synthesis of graphene sand composite from waste cooking oil for dye removal

Abdullah Sani NS, Ang WL, Mohammad AW, Nouri A, Mahmoudi E

Sci Rep, 2023 Feb 02;13(1):1931.

Waste cooking oil (WCO) appears to be a potential carbonaceous source for synthesizing graphene sand composite (GSC) adsorbent in removing pollutants. This study presents a green synthesis method of GSC using WCO as a sustainable carbon source for the synthesis of GSC through the thermal graphitization method. Characterization analysis conducted on GSCWCO verified the successful coating of WCO onto the sand surface and conversion to graphene, which possessed distinct functional groups and features of graphene materials. GSCWCO adsorbent effectiveness in removing Congo Red dye through batch adsorption was studied under the influence of different initial concentrations (20 to 100 mg/L), and the optimum pH (pH 2 to 10), contact time (5 to 240 min), and temperature (25 to 45 °C) were investigated. The GSCWCO showed removal rates of 91.5% achieved at an initial dye concentration of 20 mg L-1, 1.0 g of adsorbent dosage, a temperature of 25 °C, and 150 min of contact time. The GSCWCO exhibited a maximum capacity of 5.52 mg g-1, was well-fitted to the Freundlich isotherm model with an R2 value of 0.989 and had an adsorption mechanism that followed the pseudo-second-order kinetic model. Negative values of enthalpy (ΔH) and Gibbs free energy (ΔG) revealed that CR adsorption onto GSCWCO was a spontaneous and exothermic process. The presence of functional groups on the surface of GSCWCO with such interactions (π-π attractive forces, hydrophobic forces, and hydrogen bonding) was responsible for the anionic dye removal. Regeneration of GSCWCO adsorbent declined after four cycles, possibly due to the chemisorption of dyes with GSC that resulted in inefficient adsorption. Being a waste-to-wealth product, GSCWCO possessed great potential to be used for water treatment and simultaneously benefited the environment through the effort to reduce the excessive discharge of WCO.
Fulltext Knowledge and attitudes concerning antibiotic use and resistance among the public in Pulau Pinang, Malaysia

Halim NAAA, Chang CT, Chan HK, Hassali MA, Nouri A

Malays J Med Sci, 2018 Nov;25(6):141-147.
PMID: 30914888 MyJurnal DOI: 10.21315/mjms2018.25.6.15

The aim of this cross-sectional study was to evaluate the knowledge and attitudes concerning antibiotic use and resistance among members of the local community in Pulau Pinang, Malaysia. The study was conducted among 326 residents of the Jelutong district, Pulau Pinang state, from August to October 2013. A self-administered five-part questionnaire was used for the data collection. The respondents exhibited inadequate knowledge of antibiotics in general. Approximately 80% of them did not know the indications for antibiotic use, while 76% believed that antibiotics were useful in terms of resolving viral fever. Additionally, 52.6% believed that antibiotics could be used to treat all types of infections. Inadequate knowledge of antibiotic resistance was also evident among the respondents, since 72.9% of them did not agree that resistant bacteria can spread from human or animal to human, while 32% were unaware that bacteria can develop resistance to antibiotics. More than 60% of respondents admitted that they took antibiotics in order to accelerate their recovery from illness, while 34.8% claimed that they only stopped taking antibiotics when they felt better. The findings hence indicate that most respondents had poor knowledge and attitudes concerning antibiotic use and resistance, which suggests the need for more community-based educational campaigns designed to improve the public's knowledge and attitudes regarding antibiotics.

Decorating nanomaterials on graphene oxide (GO) can enhance its adsorption capacity and removal efficiency of water pollutants. In this study, for the first time, nano-sized polylactic acid (PLA) has been successfully decorated on the surface of GO through a facile synthesis approach. The adsorptive efficiency of GO-PLA for removing methylene blue (MB) and tetracycline (TC) from an aqueous solution was examined. The characterization confirmed the successful decoration of PLA on GO nanosheets with the nano size of PLA. It was hypothesized that the PLA was decorated on the surface of GO through covalent bonding between oxygen-containing functional groups and lactide molecules. The optimum adsorption parameters determined were at the adsorbent dose of 0.5 g L-1, pH 4, contact time of 120 min, and temperature of 318 K. The pseudo-second-order kinetic model described the contaminants' adsorption behaviour, and the intraparticle diffusion model revealed that both surface adsorption and intraparticle diffusion controlled the adsorption process. Langmuir isotherm model best described the adsorption behaviour of the pollutants on GO-PLA and demonstrated the maximum monolayer uptake capacities of MB (332.5 mg g-1) and TC (223.7 mg g-1). The adsorption results indicated that the uptake capacities of GO-PLA in comparison to GO have increased by approximately 70% and 110% for MB and TC, respectively. These observations reflect the remarkable role of nano-sized PLA that enhanced the adsorption capacity due to its additional functional group and larger surface area.
Fulltext Management of mild degenerative cervical myelopathy and asymptomatic spinal cord compression: an international survey

Brannigan JFM, Davies BM, Mowforth OD, Yurac R, Kumar V, Dejaegher J, et al.

Spinal Cord, 2024 Feb;62(2):51-58.
PMID: 38129661 DOI: 10.1038/s41393-023-00945-8

STUDY DESIGN: Cross-sectional survey.
OBJECTIVE: Currently there is limited evidence and guidance on the management of mild degenerative cervical myelopathy (DCM) and asymptomatic spinal cord compression (ASCC). Anecdotal evidence suggest variance in clinical practice. The objectives of this study were to assess current practice and to quantify the variability in clinical practice.
METHODS: Spinal surgeons and some additional health professionals completed a web-based survey distributed by email to members of AO Spine and the Cervical Spine Research Society (CSRS) North American Society. Questions captured experience with DCM, frequency of DCM patient encounters, and standard of practice in the assessment of DCM. Further questions assessed the definition and management of mild DCM, and the management of ASCC.
RESULTS: A total of 699 respondents, mostly surgeons, completed the survey. Every world region was represented in the responses. Half (50.1%, n = 359) had greater than 10 years of professional experience with DCM. For mild DCM, standardised follow-up for non-operative patients was reported by 488 respondents (69.5%). Follow-up included a heterogeneous mix of investigations, most often at 6-month intervals (32.9%, n = 158). There was some inconsistency regarding which clinical features would cause a surgeon to counsel a patient towards surgery. Practice for ASCC aligned closely with mild DCM. Finally, there were some contradictory definitions of mild DCM provided in the form of free text.
CONCLUSIONS: Professionals typically offer outpatient follow up for patients with mild DCM and/or asymptomatic ASCC. However, what this constitutes varies widely. Further research is needed to define best practice and support patient care.
