Trace odour is one of the trace material evidence that has significant value in forensic analysis. The recovery of relevant trace odour components from clothing has the potential to be a form of trace evidence that can be used to assess the likelihood of a contact between individuals in sexual and violent cases. They have the same potential as other trace evidence and can narrow down the suspect in the investigation. Studies conducted previously related to trace odour have succeeded in proving that this trace odour is unique, has its signature profile and can distinguish it from other sources such as fingerprints and DNA. This review highlights these trace odours and their persistence after being transferred, which contribute to a complete picture of the dynamics and potential application in the forensic reconstruction process. The literature was sourced from electronic databases such as Scopus, PubMed, Springer Link, Wiley On¬line Library and Science Direct. Keywords such “odour”, “trace odour”, “scent”, “volatile organic compound”, “forensic identification” were utilised. Further studies on various forms of trace odour are needed to strengthen their evidential values and be admissible to the court.

Introduction: Caspase-3 is a crucial mediator of the extrinsic apoptosis pathway. The role of caspase-3 for extrinsic apoptosis signalling is still a challenge and should be exploited in childhood ALL. This study aimed to compare the caspase-3 expression in the patient’s bone marrow before and after the induction phase of chemotherapy in childhood ALL. It will also to correlate the mean difference in caspase-3 expression between ALL standard-risk and ALL high-risk patients. Methods: Seventeen newly diagnosed ALL subjects were enrolled in this study. Caspase-3 expression in bone marrow was assessed using flow cytometry and monoclonal antibodies. A T-test and a paired T-test were used to compare between groups. The correlation coefficient between ALL groups was evaluated using Spearman’s test and linear regression with a significant p-value of 0.05. Results: The caspase-3 expression is higher after induction therapy. However, it showed an insignificant difference (16.56+12.91% vs 27.71+12.33%; p = 0.08, p > 0.05). The mean difference of caspase-3 in ALL high-risk groups was significantly higher than in ALL standard-risk groups with a positive correlation (p = 0.007, r = 0.756). Conclusion: The caspase-3 expression after induction phase chemotherapy was increased in all standard-risk and high-risk patients; other lymphoblast apoptosis markers need to be confirmed alongside caspase-3.

Introduction: Stroke is one of the most common neurological diseases, often causing death or gross physical impairment or disability. The associated risk factors such as hypertension, high cholesterol, diabetes, heart disease, and smoking should serve as warnings. However, most people are still not aware of these risks. The main aim of this study is to identify stroke awareness behavior using the construct variable from the Theory of Planned Behavior as the predictor (attitude factor, subjective norm factor, perceived behavioral factor, and intention to perform behavior). Methods: A cross-sectional study was conducted on 256 people who have a high risk of stroke at the Poncokusumo Health Center, Malang, Indonesia. The sampling technique used was purposive sampling. The authors used all the construct variables in the Theory of Planned Behavior. The stroke awareness behavior was measured using a questionnaire developed from the National Stroke Awareness Guide, while the attitude factor, subjective norm factor, perceived behavioral factor, and intention were measured using the instruments developed from standard instruments from the Theory of Planned Behavior. Structural Equation Modeling (SEM-PLS) was used to analyse the data. Result: This study found that 68.4% of respondent with high or low intention of preventing a stroke can be predicted by attitude factors, subjective norm factors, and perceived behavioral factors. While 96.1% of good or bad stroke awareness behavior can be predicted by the model used in this study, the rest (3.9%) is explained by other variables outside this research model. Conclusion: The hypothesis testing results showed that all construct variables in the Theory of Planned Behavior can be strong predictors of stroke awareness behavior. All variables in the Theory of Planned Behavior can be powerful predictors of stroke awareness behavior.

Introduction: There is an increasing demand for additional techniques to diagnose and treat cancer including CRC or colorectal cancer effectively. Utilizing antibodies as biomarker could contribute to accurate diagnosis of cancer due to its high specificity and sensitivity. One of the etiologies of CRC progression was proposed as the alterations of hexosamine biosynthetic pathway which could subsequently influence the rate-limiting enzyme, glutamine-fructose-6-phosphate aminotransferase (GFAT1). These increased enzymatic activities resulted in an elevation of glucose uptake that provides nutrients facilitating the progression of cancer cells. Therefore, we attempted to determine the potential of GFAT1 as the biomarker for CRC by correlating its expression with clinicopathological features of the patients. Methods: A total of 132 10% formalin-fixed paraffin embedded tissue were retrieved. Immunohistochemistry (IHC) was performed on the tissue sections and digital images were subsequently acquired. All the images were automatedly analyzed using IHC Profiler. GFAT1 immunoreactivity in colorectal tissues was calculated using an adapted H-score formula. Clinicopathological features of the patients were statistically correlated with the status of GFAT1. Results: Colorectal adenocarcinoma tissues had the significantly highest GFAT1 H-scores with the mean of 103.18 compared to adenoma and non-tumor tissues. There have been no significant associations between clinicopathological characteristics of the patients and the status of GFAT1 except for tumor size. Conclusion: Immunoreactivity of GFAT1 was significantly different between non-tumorous tissues and adenocarcinoma as well as between adenoma and adenocarcinoma tissues. GFAT1 could serve as one of the prognostic biomarkers or useful targets.

Introduction: The COVID-19 pandemic significantly impacted the global teaching and learning process (TnL). Unfortunately, to date, not many qualitative studies have been published specifically on the impact of COVID-19 on the Family Medicine course, particularly in Malaysia. Hence, this study aimed to explore the impact of COVID-19 pandemic on the teaching and learning experience of undergraduate students undergoing their Family Medicine course at a local university. Methods: A qualitative study using focused group discussion (FGD), was conducted among undergraduate students during the lockdown period. A semi-structured interview guide was used to interview 20 students, in their fifth undergraduate year, undertaking their fourth to fifth week of a total six-week course. They were selected using purposive snowball sampling method. There were four focus group discussions (FGD) with five students in a group. All interviews were audio-taped, transcribed verbatim, and the contents were analysed using the standard content analysis framework. Subsequently, thematic content analysis was conducted, and three major themes were produced. Results: The three major themes were (1) facilitators to learning, (2) barriers to learning, and (3) rooms for improvement. Conclusion: Although COVID-19 pandemic had significant impact on TnL of Family Medicine course among undergraduates, the students remained optimistic and proposed some improvement from their point of view. However, a creative, realistic, effective, and impactful way of TnL, particularly in clinical aspects should be developed and experimented. Technological progress and advancement should permit this idea to be achievable and implemented in near future.

Introduction: Scoliosis is characterized by an abnormal lateral curvature that may occur during a child’s growth period. Early detection and intervention are needed to prevent the progression of abnormal curvatures. While the gold standard for diagnosing idiopathic scoliosis is x-ray imaging, there is a quick and easy way to perform screening, i.e., using a smartphone. A mobile application with a built-in inclinometer and simple scoliosis tests may help detect scoliosis. Therefore, this study aimed to assess the ScoScreen mobile application’s content for early screening of AIS. Methods: We recruited five physiotherapists with more than five years of experience in paediatric and musculoskeletal and one spinal surgeon. The validity of this study was assessed using a content validity form. Content validity was assessed by calculating the Item-level Content Validity Index (I-CVI), Scale-level Content Validity Index (S-CVI), and modified kappa. Results: The results show that the content validity of ScoScreen has an excellent level of content validity (I-CVI=0.83 – 1.00). The average approach’s overall content validity index was high (S-CVI/Ave=0.94). All items in this study were excellent, with the kappa scores greater than 0.74 (kappa= 0.816 – 1). Conclusion: The development of ScoScreen for early screening of AIS was proven to have excellent content validity in this study. As a result, the Scoscreen mobile application is appropriate for early detection of AIS in terms of its content.

Introduction: The Coronavirus disease pandemic of 2019 (COVID-19) has had psychological implications and altered the public’s well-being. In response to the pandemic, mental health practitioners play an essential role in mitigating the adverse psychological effects among the public. However, as the demand for mental health services increases, the responsibilities of mental health professionals are far stretched from what they can handle. Therefore, this research is aimed to explore the psychological impact of the pandemic on the mental health practitioners in Selangor and their coping strategies. Method: A total of 10 mental health practitioners who are clinical psychologists and counselors participated in the one-to-one interview. The collected data were analysed using thematic analysis. Result: The higher client loads, the transition to virtual therapy, burnout, and anxiety were found to have an impact on the mental health practitioners’ well-being. Despite the challenging psychological impact, the mental health practitioners expressed a high level of satisfaction with their jobs, which they attributed to the supportive organisational culture and their intrinsic drive for selecting this profession. The mental health practitioners have reported that perceived organisational support, social support, and self-care approaches are effective coping mechanisms. Mindfulness skills such as breathing techniques and meditation are often practiced by the participants to calm the mind and body from a long day of work. Conclusion: The implication of the study contributes to breaking the stigmatisation of help seeking behaviour among the helping professions, as well as urging the policy makers, governments, and foundations to play a part in providing accessible and quality mental healthcare to the society.

Periosteum is a connective tissue that envelopes the outer surface of bones and is tightly bound to the underlying bone by Sharpey’s fibers. It is composed of two layers, the outer fibrous layer and the inner cambium layer. The periosteum is densely vascularised and contains an osteoprogenitor niche that serves as a repository for bone-forming cells, which makes it an essential bone-regenerating tissue and has immensely contributed to fracture healing. Due to the high vascularity of inner cambium layer of the periosteum, periosteal transplantation has been widely used in the management of bone defects and fracture by orthopedic surgeons. Nevertheless, the use of periosteal graft in the management of bone defect is limited due to its contracted nature after being harvested. This review summarizes the current state of knowledge about the structure of periosteum, and how periosteal transplantation have been used in clinical practices, with special reference on its expansion.

Introduction: The most common variety of lung cancer is non–small cell lung cancer (NSCLC) accounting for 84% of new cases. Surgery, chemotherapy and radiation are the primary treatment option. Metformin has recently been demonstrated to have an anti-tumour impact on various cancer cells. The goal of this investigation was to determine the growth inhibitory, antiproliferative, cytotoxic, apoptotic and cell cycle arrest properties of metformin HCl oral tablets on the A549 lung carcinoma cell line. Methods: The cells were treated with different dosages of an oral preparation of metformin, with untreated cells used as a control. The Trypan Blue Exclusion Assay was used to determine metformin’s inhibitory and cytotoxic effects. Flow cytometry was used to evaluate apoptosis and cell cycle arrest. Results: In a dose-dependent manner, metformin HCl was able to reduce the viability of treated cells compared to the untreated control. Cell proliferation was considerably inhibited in the treated group with the IC50 dose than in the untreated control group and the IC50 dose showed no cytotoxic effect on L929 cells. Induction of apoptosis and cell cycle arrest was observed in the IC50 dose-treated group by Flow cytometry analysis and data showed metformin oral drug causes early apoptosis and a considerable cell increase in the S phase of the cell cycle. Conclusion: Metformin inhibits cell growth and induces apoptosis and cell cycle arrest in the cell line. A comprehensive proteome examination is required to understand more about the mechanism of action of the oral metformin HCl on cancer cells.

The goal of this investigation was to determine the growth inhibitory, antiproliferative, cytotoxic, apoptotic and cell cycle arrest properties of metformin HCl oral tablets on the A549 lung carcinoma cell line. Methods: The cells were treated with different dosages of an oral preparation of metformin, with untreated cells used as a control. The Trypan Blue Exclusion Assay was used to determine metformin’s inhibitory and cytotoxic effects. Flow cytometry was used to evaluate apoptosis and cell cycle arrest. Results: In a dose-dependent manner, metformin HCl was able to reduce the viability of treated cells compared to the untreated control. Cell proliferation was considerably inhibited in the treated group with the IC50 dose than in the untreated control group and the IC50 dose showed no cytotoxic effect on L929 cells. Induction of apoptosis and cell cycle arrest was observed in the IC50 dose-treated group by Flow cytometry analysis and data showed metformin oral drug causes early apoptosis and a considerable cell increase in the S phase of the cell cycle. Conclusion: Metformin inhibits cell growth and induces apoptosis and cell cycle arrest in the cell line. A comprehensive proteome examination is required to understand more about the mechanism of action of the oral metformin HCl on cancer cells.","PeriodicalId":40029,"journal":{"name":"Malaysian Journal of Medicine and Health Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44729412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: This methodological research study aimed to measure content validity and reliability of a newly developed questionnaire of knowledge, attitudes, and self-reported practices towards pureed diet preparation (KAP DYS Puree) among hospital food handlers for dysphagia management. Methods: The study was conducted through face validation, content validation, content reliability and construct validation. A cross-sectional design with convenience sampling was carried out involving 4 panels for face validation, 10 raters for content validity and 161 food handlers participated for Exploratory Factor Analysis (EFA), while 30 food handlers were involved for test-retest reliability. The questionnaire which consisted of 40 items distributed into 3 domains and was assessed and analyzed using modified kappa (k*) for reliability. Results: Content Validity Index revealed the following I-CVI values: knowledge = 0.915, attitudes = 0.922 and self-reported practices = 0.900 and modified kappa values (k*) knowledge = 0.983, attitudes = 0.9214 and self-reported practices = 0.899. The EFA was employed for two dimensions which were self-reported practices and attitudes based on principal axis of factoring with varimax rotation. The factor analysis yielded two factors with a total of 10 items in the attitudes domain and two factors with a total of 9 items in the self-reported practices domain that had satisfactory factor loading (> 0.3). The Kaiser-Meyer-Olkin (KMO) values for attitudes = 0.816 and self-reported practices = 0.776. Bartlett’s test of sphericity was significant at p < 0.0001 for attitudes and self-reported practices indicating the suitability of this data for factor analysis. Interclass Correlation Index (ICC) values for attitudes = 0.739 and self-reported practices = 0.789. Conclusion: This instrument can be used as a need assessment tool in the development of a comprehensive training module for pureed diet preparations in dysphagia management.
