Waste recycling: utilization of coffee grounds and kitchen waste in vermicomposting

Adi AJ, Noor ZM

Bioresour Technol, 2009 Jan;100(2):1027-30.
PMID: 18752936 DOI: 10.1016/j.biortech.2008.07.024

Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratio (T(1)), cow dung: coffee grounds in 30:70 ratio (T(2)), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratio (T(3)). The multiplication of earthworms in terms of numbers and weight were measured at the end of vermicomposting. Consequently, only T(2) showed significant increase (from it initial stage) compared to other treatments. The presence of coffee grounds in T(2) and T(3) showed higher percentage of nutrient elements in vermicompost produced. The data reveal that coffee grounds can be decomposed through vermicomposting and help to enhance the quality of vermicompost produced rather than sole use of kitchen waste in vermicomposting.

Delay in commencing treatment in patients diagnosed with smear-positive pulmonary tuberculosis (PTB) may promote the spread of PTB in the community. Socio-demographic and clinical data from 169 patients (119 retrospectively and 50 prospectively collected) treated for smear-positive PTB in our hospital Chest Clinic from June 2002 to February 2003 were analysed. One hundred and fifty eight (93.5%) patients were started on treatment in less than 7 days from the time when the report first became available while 11 (6.5%) patients had their treatment started > or = 7 days. The median 'discovery to treatment' window was 1 day (range, 0 to 24 days). Of the factors studied, longevity of symptoms, absence of fever or night sweats and having sought traditional medicine were associated with delay in treatment commencement. The urgency and importance of anti-TB treatment should be emphasized especially to patients who are inclined towards treatment with traditional medicine.

Vermiremoval of heavy metal in sewage sludge by utilising Lumbricus rubellus

Azizi AB, Lim MP, Noor ZM, Abdullah N

Ecotoxicol Environ Saf, 2013 Apr;90:13-20.
PMID: 23294636 DOI: 10.1016/j.ecoenv.2012.12.006

Experiments were conducted to remove heavy metals (Cr, Cd, Pb, Cu and Zn) from urban sewage sludge (SS) amended with spent mushroom compost (SMC) using worms, Lumbricus rubellus, for 105 days, after 21 days of pre-composting. Five combinations of SS/SMC treatments were prepared in triplicate along with a control for each treatment in microcosms. Analysis of the earthworms' multiplication and growth and laboratory analysis were conducted during the tenth and fifteenth week of vermicomposting. Our result showed that the final biomass of earthworms (mg) and final number of earthworms showed significant differences between treatments i.e. F=554.70, P=0.00 and F=729.10, P=0.00 respectively. The heavy metals Cr, Cd and Pb contained in vermicompost were lower than initial concentrations, with 90-98.7 percent removal on week ten. However, concentrations of Cu and Zn, that are considered as micronutrients, were higher than initial concentrations, but they were 10-200-fold lower than the EU and USA biosolid compost limits and Malaysian Recommended Site Screening Levels for Contaminated Land (SSLs). An increment of heavy metals were recorded in vermicompost for all treatments on week fifteen compared to week ten, while concentration of heavy metals in earthworms' tissue were lower compared to vermicompost. Hence, it is suggested that earthworms begin to discharge heavy metals into their surroundings and it was evident that the earthworms' heavy metals excretion period was within the interval of ten to fifteen weeks.

Ismail FF, Mohamed Noor Z, Muda SM, Ab Rahman NS

J Pharm Bioallied Sci, 2020 Nov;12(Suppl 2):S681-S690.
PMID: 33828361 DOI: 10.4103/jpbs.JPBS_383_19

Context: The attitude of healthcare professionals and social supports give big influence toward self-esteem of physically disabled people.
Aims: To explore how impairments could affect the self-esteem of physically disabled people and how healthcare professionals and social support boost their self-esteem.
Materials and Methods: This study was conducted qualitatively whereby face-to-face interviews were conducted among 10 participants with physical disabilities. Participants were recruited from two rehabilitation centres in Kuantan, namely Community-based rehabilitation and rehabilitation, occupational therapy, and physiotherapy of public hospital in Kuantan. Interviews were conducted using the developed interview guide that explored on the disabled peoples' self-esteem and motivation, feelings toward attitude of the healthcare professionals, and satisfaction toward the physical, services, and social support from the healthcare professionals. Thematic analysis was done to identify the themes emerged from the interview transcripts.
Results: Five males and five females with age ranging from 31 to 58 years were interviewed. Five are still working or studying post impairments. Participants claimed being low self-esteem resulted from negative perception from the society, issue of rejection, being discriminated, and difficulty in getting support from the society. Most of the participants asserted that they gained their motivation and self-esteem due to the continuous support from various groups, such as their spouses, family members, colleagues, employers, and healthcare professionals.
Conclusions: Despite heavy workload and stressful working environment, positive attitude showed by the healthcare professionals is highly praised. Hence, this will indirectly improve the self-esteem, motivation, and rehabilitation progress of physically disabled people.
Reprint of: Cling film plastic wrap: An innovation for dead body packaging, preservation and transportation by first responders as a replacement for cadaver body bag in large scale disasters

Cadaver body bags are the conventional method to contain a human body or human remains, which includes the use for storage and transportation of the deceased at any crime scene or disaster scene. During disasters, most often than not, the first responders including the police will be equipped with cadaver body bags to do scene processing of human remains and collection of personal belongings at the disaster site. However, in an unanticipated large scale disasters involving hundreds and thousands of fatalities, cadaver body bags supplies may be scarce. The authors have therefore innovated the cling film plastic wrap as an alternative for the cadaver body bag used at the disaster site. The plastic wrap was tested on six different experimental subjects, i.e. both adult and child mannequins; body parts of the mannequin figure (arm and hand); a human adult subject and an unknown dead body. The strengths of the cling film plastic wrap are discussed in comparison with the cadaver body bag in the aspects of costing, weight, duration of the wrap, water and body fluid resistant properties, visibility and other advantages. An average savings of more than 5000% are noted for both adult body wrap and child body wrap compared to the cadaver body wrap. This simply means that the authors can either wrap 25 adult dead bodies or 80 children dead bodies with the cost of 1 cadaver body bag. The cling film plastic wrap has proven to have significant innovation impact for dead body management particularly by the first responders in large scale disasters. With proper handling of dead bodies, first responders can manage the dead with dignity and respect in an overwhelmed situation to facilitate the humanitarian victim identification process later.
Fulltext Exploring Culture, Religiosity and Spirituality Influence on Antihypertensive Medication Adherence Among Specialised Population: A Qualitative Ethnographic Approach

Patient Prefer Adherence, 2021;15:2249-2265.
PMID: 34675490 DOI: 10.2147/PPA.S319469

Background: Hypertension is one of the major risk factors of stroke and leading risk factors for global death. Inadequate control of blood pressure due to medication non-adherence remains a challenge and identifying the underlying causes will provide useful information to formulate suitable interventions.
Purpose: This study aimed to explore the roles of culture, religiosity, and spirituality on adherence to anti-hypertensive medications.
Methodology: A semi-structured qualitative interview was used to explore promoters and barriers to medication adherence among hypertensive individuals residing in urban and rural areas of Perak State, West Malaysia. Study participants were individuals who are able to comprehend either in Malay or English, above 18 years old and on antihypertensive medications. Interview transcriptions from 23 participants were coded inductively and analyzed thematically. Codes generated were verified by three co-investigators who were not involved in transcribing process. The codes were matched with quotations and categorized using three levels of themes named as organizing, classifying and general themes.
Results: Cultural aspects categorized as societal and communication norms were related to non-adherence. The societal norms related to ignorance, belief in testimony and anything "natural is safe" affected medication adherence negatively. Communication norms manifested as superficiality, indirectness and non-confrontational were also linked to medication non-adherence. Internal and organizational religiosity was linked to increased motivation to take medication. In contrast, religious misconception about healing and treatment contributed towards medication non-adherence. The role of spirituality remains unclear and seemed to be understood as related to religiosity.
Conclusion: Culture and religiosity (C/R) are highly regarded in many societies and shaped people's health belief and behaviour. Identifying the elements and mechanism through which C/R impacted adherence would be useful to provide essential information for linking adherence assessment to the interventions that specifically address causes of medication non-adherence.

A survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association conducted in 2022 found considerable variation in care across the region. A Call to Action is proposed to improve acute care, rehabilitation and secondary fracture prevention across Asia Pacific.
PURPOSE: Fragility fractures impose a substantial burden on older people and their families, healthcare systems and national economies. The current incidence of hip and other fragility fractures across the Asia Pacific region is enormous and set to escalate rapidly in the coming decades. This publication describes findings of a survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association (APOA) conducted in 2022.
METHODS: The survey was developed as a collaboration between the Asia Pacific Osteoporosis and Fragility Fracture Society and the Asia Pacific Fragility Fracture Alliance, and included questions relating to aspects of care upon presentation, during surgery and mobilisation, secondary fracture prevention, and access to specific services.
RESULTS: In total, 521 APOA members completed the survey and marked variation in delivery of care was evident. Notable findings included: Fifty-nine percent of respondents indicated that analgesia was routinely initiated in transit (by paramedics) or within 30 minutes of arrival in the Emergency Department. One-quarter of respondents stated that more than 80% of their patients underwent surgery within 48 hours of admission. One-third of respondents considered non-hip, non-vertebral fractures to merit assessment of future fracture risk. One-third of respondents reported the presence of an Orthogeriatric Service in their hospital, and less than a quarter reported the presence of a Fracture Liaison Service.
CONCLUSION: A Call to Action for all National Orthopaedic Associations affiliated with APOA is proposed to improve the care of fragility fracture patients across the region.
