Saimon R, Choo WY, Bulgiba A

Asia Pac J Public Health, 2015 Mar;27(2):NP2079-92.
PMID: 23513006 DOI: 10.1177/1010539513480229

Understanding the factors influencing physical activity (PA) in the Asia-Pacific region is critical, given the high prevalence of inactivity in this area. The photovoice technique explores the types of PA and factors influencing PA among adolescents in Kuching, Sarawak. A total of 160 photographs were collected from participants (adolescents, n = 22, mean age = 14.27 ± 0.7 years, and parents, n = 8, mean age = 48 ± 6.8 years). Data analysis used constant comparison methods of a grounded theory. The Analysis Grid for Environments Linked to Obesity was used to categorize PA factors. Study findings were centered on the concept of safety, facilities, parental restriction, friends, cultural traits, media, community cohesiveness, and weather. The central theme was "feeling unsafe" when being outdoors. To promote PA behavior, provision of PA facilities needs to be supported by other programs that build on peer support, crime prevention, and traffic safety, together with other educational campaigns.

2018 APLAR axial spondyloarthritis treatment recommendations

Tam LS, Wei JC, Aggarwal A, Baek HJ, Cheung PP, Chiowchanwisawakit P, et al.

Int J Rheum Dis, 2019 Mar;22(3):340-356.
PMID: 30816645 DOI: 10.1111/1756-185X.13510

INTRODUCTION: Despite the availability of axial spondyloarthritis (SpA) recommendations proposed by various rheumatology societies, we considered that a region-specific guideline was of substantial added value to clinicians of the Asia-Pacific region, given the wide variations in predisposition to infections and other patient factors, local practice patterns, and access to treatment across countries.
MATERIALS AND METHODS: Systematic reviews were undertaken of English-language articles published between 2000 and 2016, identified from MEDLINE using PubMed, EMBASE and Cochrane databases. The strength of available evidence was graded using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Recommendations were developed through consensus using the Delphi technique.
RESULTS: Fourteen axial SpA treatment recommendations were developed based on evidence summaries and consensus. The first 2 recommendations cover non-pharmacological approaches to management. Recommendations 3 to 5 describe the following: the use of non-steroidal anti-inflammatory drugs as first-line symptomatic treatment; the avoidance of long-term corticosteroid use; and the utility of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) for peripheral or extra-articular manifestations. Recommendation 6 refers to the indications for biological DMARDs (bDMARDs). Recommendation 7 deals specifically with screening for infections endemic to Asia, prior to use of bDMARDs. Recommendations 7 to 13 cover the role of bDMARDs in the treatment of active axial SpA and include related issues such as continuing therapy and use in special populations. Recommendation 14 deals with the utility of surgical intervention in axial SpA.
CONCLUSION: These recommendations provide up-to-date guidance for treatment of axial SpA to help meet the needs of patients and clinicians in the Asia-Pacific region.

2018 update of the APLAR recommendations for treatment of rheumatoid arthritis

Lau CS, Chia F, Dans L, Harrison A, Hsieh TY, Jain R, et al.

Int J Rheum Dis, 2019 Mar;22(3):357-375.
PMID: 30809944 DOI: 10.1111/1756-185X.13513

AIM: To update recommendations based on current best evidence concerning the treatment of rheumatoid arthritis (RA), focusing particularly on the role of targeted therapies, to inform clinicians on new developments that will impact their current practice.
MATERIALS AND METHODS: A search of relevant literature from 2014 to 2016 concerning targeted therapies in RA was conducted. The RA Update Working Group evaluated the evidence and proposed updated recommendations using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, to describe the quality of evidence and strength of recommendations. Recommendations were finalized through consensus using the Delphi technique.
RESULTS: This update provides 16 RA treatment recommendations based on current best evidence and expert clinical opinion. Recommendations 1-3 deal with the use of conventional synthetic disease-modifying antirheumatic drugs. The next three recommendations (4-6) cover the need for screening and management of infections and comorbid conditions prior to starting targeted therapy, while the following seven recommendations focus on use of these agents. We address choice of targeted therapy, switch, tapering and discontinuation. The last three recommendations elaborate on targeted therapy for RA in special situations such as pregnancy, cancer, and major surgery.
CONCLUSION: Rheumatoid arthritis remains a significant health problem in the Asia-Pacific region. Patients with RA can benefit from the availability of effective targeted therapies, and these updated recommendations provide clinicians with guidance on their use.

Purmal K, Alam MK, Pohchi A, Abdul Razak NH

PLoS One, 2013;8(12):e84202.
PMID: 24367643 DOI: 10.1371/journal.pone.0084202

Intermaxillary (IMF) screws feature several advantages over other devices used for intermaxillary fixation, but using cone beam computed tomography (CBCT) scans to determine the safe and danger zones to place these devices for all patients can be expensive. This study aimed to determine the optimal interradicular and buccopalatal/buccolingual spaces for IMF screw placement in the maxilla and mandible. The CBCT volumetric data of 193 patients was used to generate transaxial slices between the second molar on the right to the second molar on the left in both arches. The mean interradicular and buccopalatal/buccolingual distances and standard deviation values were obtained at heights of 2, 5, 8 and 11 mm from the alveolar bone crest. An IMF screw with a diameter of 1.0 mm and length of 7 mm can be placed distal to the canines (2 - 11 mm from the alveolar crest) and less than 8 mm between the molars in the maxilla. In the mandible, the safest position is distal to the first premolar (more than 5 mm) and distal to the second premolar (more than 2 mm). There was a significant difference (p<0.05) between the right and left quadrants. The colour coding 3D template showed the safe and danger zones based on the mesiodistal, buccopalatal and buccolingual distances in the maxilla and mandible.The safest sites for IMF screw insertion in the maxilla were between the canines and first premolars and between the first and second molars. In the mandible, the safest sites were between the first and second premolars and between the second premolar and first molar. However, the IMF screw should not exceed 1.0 mm in diameter and 7 mm in length.

Malays Orthop J, 2007;1(1):34-38.
MyJurnal

Domestic paediatric hand injuries make up the bulk of overall paediatric hand injuries. This is a retrospective study of domestic paediatric hand injuries admitted into an urban hospital that required surgical intervention. The most common injuries sustained were tendon injuries (24%), total amputations (20%) and lacerations wounds (16%). Accordingly the most common surgical interventions were tendon repairs (28%), toilet suturing (24%) and refashioning (20%). Parents and care providers need to be more vigilant and careful when supervising children including ensuring the safe storage of dangerous items. Sharp items may require additional safety features and warning labels.

Ahmad NA, Yook Heng L, Salam F, Mat Zaid MH, Abu Hanifah S

Sensors (Basel), 2019 Nov 05;19(21).
PMID: 31694284 DOI: 10.3390/s19214813

A developed colorimetric pH sensor film based on edible materials for real-time monitoring of food freshness is described. The mixed natural dyes from edible plants Clitoria sp and Brassica sp were extracted and incorporated into ι-carrageenan film as a colorimetric pH sensor film for monitoring food spoilage and its freshness. The color changes of the developed colorimetric sensor film were measured with chromametry and UV-vis spectroscopy, respectively. Experimental results show that colorimetric pH sensor film demonstrated statistically significant differences (p < 0.05) between CIE-L*a*b* coordinates color system indicated that the developed colorimetric sensor film was able to give a gradual change in color over a wide pH range. The color of the colorimetric sensor film also changes discretely and linearly with factors that contribute to food spoilage using shrimp and durian samples. Moreover, the developed colorimetric pH sensor film has the potential to be used as a safe, non-destructive testing and also a flexibly visual method for direct assessment of food freshness indicator during storage.

A Heart for Travel: Travel Health Considerations for Patients with Heart Disease and Cardiac Devices

Flaherty G, De Freitas S

Ir Med J, 2016 Dec 12;109(10):486.
PMID: 28644591

Cardiovascular disease is the leading cause of death in adult international travellers. Patients living with heart disease should receive specific, individualised pre-travel health advice. The purpose of this article is to provide evidence-based advice to physicians who are consulted by travellers with cardiovascular disease. Fitness-to-travel evaluation will often be conducted by the general practitioner but other medical specialists may also be consulted for advice. Patients with chronic medical conditions should purchase travel health insurance. The general pre-travel health consultation addresses food and water safety, insect and animal bite avoidance, malaria chemoprophylaxis, and travel vaccinations. Patients with devices such as cardiac pacemakers should be familiar with how these may be affected by travel. Cardiac medications may cause adverse effects in cold or hot environments, and specific precautions must be followed by anticoagulated travellers. The physician should be aware of how to access medical care abroad, and of the potential for imported tropical diseases in returned travellers.

A Lean Approach to Evaluating Prescribing Errors in Medication Reconciliation

Putra Y, Yusof MM

Stud Health Technol Inform, 2021 May 27;281:814-815.
PMID: 34042691 DOI: 10.3233/SHTI210288

We evaluated medication reconciliation processes of a qualitative case study at a 1000-bed public hospital. Lean tools were applied to identify factors contributing to prescribing errors and propose process improvement. Errors were attributed to the prescriber's skills, high workload, staff shortage, poor user attitude and rigid system function. Continuous evaluation of medication reconciliation efficiency is imperative to identify and mitigate errors and increase patient safety.

Fulltext A New Pedestrian Crossing Level of Service (PCLOS) Method for Promoting Safe Pedestrian Crossing in Urban Areas

Ahmed T, Moeinaddini M, Almoshaogeh M, Jamal A, Nawaz I, Alharbi F

Int J Environ Res Public Health, 2021 08 20;18(16).
PMID: 34444563 DOI: 10.3390/ijerph18168813

Crosswalks are critical locations in the urban transport network that need to be designed carefully as pedestrians are directly exposed to vehicular traffic. Although various methods are available to evaluate the level of service (LOS) at pedestrian crossings, pedestrian crossing facilities are frequently ignored in assessing crosswalk conditions. This study attempts to provide a comprehensive framework for evaluating crosswalks based on several essential indicators adopted from different guidelines. A new pedestrian crossing level of service (PCLOS) method is introduced in this research, with an aimto promote safe and sustainable operations at such locations. The new PCLOS employs an analytical point system to compare existing street crossing conditions to the guidelines' standards, taking into account the scores and coefficients of the indicators. The quantitative scores and coefficients of indicators are assigned based on field observations and respondent opinions. The method was tested to evaluate four pedestrian crosswalks in the city of Putrajaya, Malaysia. A total of 17 indicators were selected for the study after a comprehensive literature review. Survey results show that the provision of a zebra crossing was the most critical indicator at the pedestrian crossings, while drainage near crosswalks was regarded as the least important. Four indicators had a coefficient value above 4, indicating that these are very critical pedestrian crossing facilities and significantly impact the calculation of LOS for pedestrian crossings. Four crosswalks were evaluated using the proposed method in Putrajaya, Malaysia. The crosswalk at the Ministry of Domestic Trade Putrajaya got the "PCLOS A". In contrast, the midblock crossing in front of the Putrajaya Corporation was graded "PCLOS C". While the remaining two crosswalks were graded as "PCLOS B" crosswalks. Based on the assigned PCLOS grade, the proposed method could also assist in identifying current design and operation issues in existing pedestrian crossings and providing sound policy recommendations for improvements to ensure pedestrian safety.

A Review on Mycotoxins in Food and Feed: Malaysia Case Study

Afsah-Hejri L, Jinap S, Hajeb P, Radu S, Shakibazadeh S

Compr Rev Food Sci Food Saf, 2013 Nov;12(6):629-651.
PMID: 33412719 DOI: 10.1111/1541-4337.12029

Fungi are distributed worldwide and can be found in various foods and feedstuffs from almost every part of the world. Mycotoxins are secondary metabolites produced by some fungal species and may impose food safety risks to human health. Among all mycotoxins, aflatoxins (AFs), ochratoxin A (OTA), trichothecenes, deoxynivalenol (DON and T-2 toxin), zearalenone (ZEN), and fumonisins (FMN) have received much attention due to high frequency and severe health effects in humans and animals. Malaysia has heavy rainfall throughout the year, high temperatures (28 to 31 °C), and high relative humidity (70% to 80% during wet seasons). Stored crops under such conditions can easily be contaminated by mycotoxin-producing fungi. The most important mycotoxins in Malaysian foods are AFs, OTA, DON, ZEN, and FMN that can be found in peanuts, cereal grains, cocoa beans, and spices. AFs have been reported to occur in several cereal grains, feeds, nuts, and nut products consumed in Malaysia. Spices, oilseeds, milk, eggs, and herbal medicines have been reported to be contaminated with AFs (lower than the Malaysian acceptable level of 35 ng/g for total AFs). OTA, a possible human carcinogen, was reported in cereal grains, nuts, and spices in Malaysian market. ZEN was detected in Malaysian rice, oat, barley, maize meal, and wheat at different levels. DON contamination, although at low levels, was reported in rice, maize, barley, oat, wheat, and wheat-based products in Malaysia. FMN was reported in feed and some cereal grains consumed in Malaysia. Since some food commodities are more susceptible than others to fungal growth and mycotoxin contamination, more stringent prevention and control methods are required.

Farah Syazana Ahmad Shahabuddin, Nur Hazirah Ahmat, Ahmed Ikhwan Mohamad, Lau, Kit Mun, Siti Aisyah Mohd Yusof, Teh, Pei Chiek, et al.

International e-Journal of Science, Medicine & Education, 2015;9(2):13-21.
MyJurnal

Background: Misinterpretation of abbreviations by healthcare workers has been reported to compromise patient safety. Medical students are future doctors. We explored how early medical students acquired the practice of using abbreviations, and their ability to interpret commonly used abbreviations in medical practice.

Method: Eighty junior and 74 senior medical students were surveyed using a self-administered questionnaire designed to capture demographic data; frequency and reasons for using abbreviations; from where abbreviations were learned; frequency of encountering abbreviations in medical practice; prevalence of mishaps due to misinterpretation; and the ability of students to correctly interpret commonly used abbreviations. Comparisons were made between senior and junior medical students.

Results: Abbreviation use was highly prevalent among junior and senior medical students. They acquired the habit mainly from the clinical notes of doctors in the hospital. They used abbreviations mainly to save time, space and avoid writing in full sentences. The students experienced difficulties, frustrations and often resorted to guesswork when interpreting abbreviations; with junior students experiencing these more than senior students. The latter were better at interpreting standard and non-standard abbreviations. Nevertheless, the students felt the use of abbreviations was necessary and acceptable. Only a few students reported encountering mishaps in patient management as a result of misinterpretation of abbreviations.

Conclusion: Medical students acquired the habit of using abbreviations early in their training. Senior students knew more and correctly interpreted more standard and non-standard abbreviations compared to junior students. Medical students should be taught to use standard abbreviations only.

A game of Chinese whispers in Malaysia: contextual analysis of child road safety education

Puvanachandra P, Kulanthayan S, Hyder AA

Qual Health Res, 2012 Nov;22(11):1476-85.
PMID: 22910586 DOI: 10.1177/1049732312457245

In 2006, the Malaysian government began implementing road safety education (RSE) programs in primary schools, involving numerous stakeholders. We interviewed 19 stakeholders. Thematic analysis led to the identification of four themes: road traffic injuries (RTIs) among children in Malaysia, the role of RSE, factors affecting successful implementation, and intersectoral involvement. The latter was identified as a significant strength of the overall approach to implementation, and is one of the first examples in Malaysia and in the region of such an approach. Lack of official documentation surrounding ownership, funding responsibilities, and roles among the various sectors led to resistance from some groups. Although we know from scientific studies what works in terms of reducing RTIs, the more important question is how such interventions can be successfully and sustainably implemented, particularly in low- and middle-income countries (LMIC). The results of this study permit stronger understanding of issues surrounding the implementation of RTI interventions in LMIC.

Fulltext A leadless intracardiac transcatheter pacing system

Reynolds D, Duray GZ, Omar R, Soejima K, Neuzil P, Zhang S, et al.

N Engl J Med, 2016 Feb 11;374(6):533-41.
PMID: 26551877 DOI: 10.1056/NEJMoa1511643

BACKGROUND: A leadless intracardiac transcatheter pacing system has been designed to avoid the need for a pacemaker pocket and transvenous lead.
METHODS: In a prospective multicenter study without controls, a transcatheter pacemaker was implanted in patients who had guideline-based indications for ventricular pacing. The analysis of the primary end points began when 300 patients reached 6 months of follow-up. The primary safety end point was freedom from system-related or procedure-related major complications. The primary efficacy end point was the percentage of patients with low and stable pacing capture thresholds at 6 months (≤2.0 V at a pulse width of 0.24 msec and an increase of ≤1.5 V from the time of implantation). The safety and efficacy end points were evaluated against performance goals (based on historical data) of 83% and 80%, respectively. We also performed a post hoc analysis in which the rates of major complications were compared with those in a control cohort of 2667 patients with transvenous pacemakers from six previously published studies.
RESULTS: The device was successfully implanted in 719 of 725 patients (99.2%). The Kaplan-Meier estimate of the rate of the primary safety end point was 96.0% (95% confidence interval [CI], 93.9 to 97.3; P<0.001 for the comparison with the safety performance goal of 83%); there were 28 major complications in 25 of 725 patients, and no dislodgements. The rate of the primary efficacy end point was 98.3% (95% CI, 96.1 to 99.5; P<0.001 for the comparison with the efficacy performance goal of 80%) among 292 of 297 patients with paired 6-month data. Although there were 28 major complications in 25 patients, patients with transcatheter pacemakers had significantly fewer major complications than did the control patients (hazard ratio, 0.49; 95% CI, 0.33 to 0.75; P=0.001).
CONCLUSIONS: In this historical comparison study, the transcatheter pacemaker met the prespecified safety and efficacy goals; it had a safety profile similar to that of a transvenous system while providing low and stable pacing thresholds.

Malays J Pathol, 2004 Jun;26(1):69-71.
PMID: 16190110

Virus isolation and accurate characterization plays a crucial role in the rapid identification of the causative agents of infectious disease outbreaks especially if the causative viruses are novel where no pre-existing diagnostic reagents would be available. A new cell culture tube, named Jui Meng (JM) Cell Culture Tube, was developed to reduce the cost and improve the efficiency and biosafety of work pertaining to virus isolation. The design of the tube is based heavily on the principle of practicability, functionality, biosafety and long-term cost saving for diagnostic laboratory work in virus isolation. It is designed to culture an initial inoculum of one milliliter of culture medium containing 1 x 10(4) to 1 x 10(5) cells/ml.

Fulltext A post hoc analysis of the long-term safety and efficacy of perampanel in Asian patients with epilepsy

Inoue Y, Kaneko S, Hsieh PF, Meshram C, Lee SA, Aziz ZA, et al.

Epilepsia, 2019 03;60 Suppl 1:60-67.
PMID: 30869167 DOI: 10.1111/epi.14645

This post hoc analysis assessed the long-term safety, tolerability, and efficacy of perampanel in Asian patients with refractory focal seizures; an additional analysis assessed the effect of perampanel on focal impaired awareness seizures (FIAS) with focal to bilateral tonic-clonic (FBTC) seizures. In this subanalysis, data from Asian patients ≥12 years of age who had focal seizures with FBTC seizures despite taking one to 3 concomitant antiepileptic drugs at baseline, and who had entered either the long-term extension phase of 3 phase-3 perampanel trials (study 307) or the 10-week extension phase of study 335, were analyzed for the effect of perampanel on duration of exposure, safety, and seizure outcomes. Of 874 Asian patients included in the analysis, 205 had previously received placebo during the double-blind phase-3 trials and 669 had previously received perampanel 2-12 mg/day; 313 had FIAS with FBTC seizures at core study baseline. The median duration of exposure to perampanel was 385.0 days, and the retention rate at one year was 62.6%. Overall, during the first 52 weeks of perampanel treatment, 777 patients (88.9%) had treatment-emergent adverse events (TEAEs), most of which were mild to moderate in severity. The most frequent TEAEs were dizziness (47.1%), somnolence (22.3%), and nasopharyngitis (17.4%). During the first 52 weeks of perampanel treatment, median percent change in seizure frequency per 28 days from pre-perampanel baseline for all focal seizures was -28.1%, and -51.7% for FIAS with FBTC seizures. The 50% responder rate relative to pre-perampanel baseline for all focal seizures was 33.8%, and 51.1% for FIAS with FBTC seizures. Long-term treatment with perampanel in Asian patients had safety, tolerability, and efficacy similar to that of the global population in the phase-3 trials and extension study 307. The safety profile and response rate suggest benefit for an Asian population of patients with refractory epilepsy.

Fulltext A review of cosmetic and personal care products: halal perspective and detection of ingredient

Hashim, P., Mat Hashim, D.

Pertanika Journal of Science & Technology, 2013;21(2):281-292.
MyJurnal

The term halal refers to what ispermitted by Islamic law. It is a basic need for Muslims and encompasses all materials used in everyday life including cosmetics.Muslims want to be assured that the ingredients,handling, processing, distribution, transportation and types of cosmetic used are halal compliant. The halal aspects of cosmetic and personal care products cover ingredients, all the processes involved in production right up to delivery to consumers, safety and product efficacy evaluations. In order to verify halal compliance of cosmetic products, a method of detecting halal and non-halal ingredients is very important and critically needed. Halal cosmetic standards, halal certification and the halal logo can be used as benchmarks for halal compliance. In view of the importance of cosmetic and personal care products from the halal perspective, this review will cover the halal principles, halal cosmetic and personal care products, ingredients, standard and certification as well as safety. The development of the process of detecting non-halal ingredients and authenticating halal ingredients for potential cosmetic applications in recent years are included in this paper.

Al-Qaysi ZT, Zaidan BB, Zaidan AA, Suzani MS

Comput Methods Programs Biomed, 2018 Oct;164:221-237.
PMID: 29958722 DOI: 10.1016/j.cmpb.2018.06.012

CONTEXT: Intelligent wheelchair technology has recently been utilised to address several mobility problems. Techniques based on brain-computer interface (BCI) are currently used to develop electric wheelchairs. Using human brain control in wheelchairs for people with disability has elicited widespread attention due to its flexibility.
OBJECTIVE: This study aims to determine the background of recent studies on wheelchair control based on BCI for disability and map the literature survey into a coherent taxonomy. The study intends to identify the most important aspects in this emerging field as an impetus for using BCI for disability in electric-powered wheelchair (EPW) control, which remains a challenge. The study also attempts to provide recommendations for solving other existing limitations and challenges.
METHODS: We systematically searched all articles about EPW control based on BCI for disability in three popular databases: ScienceDirect, IEEE and Web of Science. These databases contain numerous articles that considerably influenced this field and cover most of the relevant theoretical and technical issues.
RESULTS: We selected 100 articles on the basis of our inclusion and exclusion criteria. A large set of articles (55) discussed on developing real-time wheelchair control systems based on BCI for disability signals. Another set of articles (25) focused on analysing BCI for disability signals for wheelchair control. The third set of articles (14) considered the simulation of wheelchair control based on BCI for disability signals. Four articles designed a framework for wheelchair control based on BCI for disability signals. Finally, one article reviewed concerns regarding wheelchair control based on BCI for disability signals.
DISCUSSION: Since 2007, researchers have pursued the possibility of using BCI for disability in EPW control through different approaches. Regardless of type, articles have focused on addressing limitations that impede the full efficiency of BCI for disability and recommended solutions for these limitations.
CONCLUSIONS: Studies on wheelchair control based on BCI for disability considerably influence society due to the large number of people with disability. Therefore, we aim to provide researchers and developers with a clear understanding of this platform and highlight the challenges and gaps in the current and future studies.

Fulltext A review of ethnobotany, phytochemistry, antimicrobial pharmacology and toxicology of Nigella sativa L

Hossain MS, Sharfaraz A, Dutta A, Ahsan A, Masud MA, Ahmed IA, et al.

Biomed Pharmacother, 2021 Nov;143:112182.
PMID: 34649338 DOI: 10.1016/j.biopha.2021.112182

Nigella sativa L. is one of the most extensively used traditional medicinal plants. This widely studied plant is known to display diverse pharmacological actions, including antimicrobial activities. Current literature has documented its multi-target mode of antimicrobial actions. N. sativa or its bioactive compounds, such as thymoquinone, can induce oxidative stress, cell apoptosis (by producing reactive oxygen species), increase membrane permeability, inhibit efflux pumps, and impose strong biocidal actions. Despite its well-documented antimicrobial efficacy in the experimental model, to the best of our knowledge its antimicrobial mechanisms highlighting the multi-targeting properties have yet to be well discussed. Is N. sativa or thymoquinone a valuable lead compound for therapeutic development for infectious diseases? Are N. sativa's bioactive compounds potential antimicrobial agents or able to overcome antimicrobial resistance? This review aims to discuss the antimicrobial pharmacology of N. sativa-based treatments. Additionally, it provides a holistic overview of the ethnobotany, ethnopharmacology, and phytochemistry of N. sativa.

Fulltext A review of farm tractor overturning accidents and safety

Mohammed Shu'aibu Abubakar, Desa Ahmad, Akande, Bukola Fatai

Pertanika Journal of Science & Technology, 2010;18(2):-.
MyJurnal

Tractor rollover occurs when a tractor tips sideways or backwards and overturns, potentially crushing the operator. Rollovers are typically considered to occur more frequently during a sharp turn at a high speed on sloping terrains, although data show that rollovers do occur on flat land after hitting obstacles or through inappropriate use and hitching of implements. It is important to highlight that tractor overturns are the major cause of death in farm operations. The overturns are as a result of interactions between the tractor operator, the tractor and the environment. A review of the relevant literature reveals that more than 800 people are killed each year in tractor accidents, and for every person killed, at least 40 others are injured. This paper focuses on tractor overturns because they account for more than half of all the tractor-related deaths. In addition, farm tractor operational safety principles are also highlighted.
