Some of the beneficial biocompatible properties of hydroxyapatite [Ca10(PO4)6(OH)2]; the major component and an essential ingredient of normal bone and teeth, are that it is rapidly integrated into the human body and will bond to bone forming indistinguishable unions. But, before new materials are approved for medical use, mutagenesis systems to exclude cytotoxic, mutagenic or carcinogenic properties are applied worldwide. This study aimed to detect any chromosomal aberrations induced by the synthetic hydroxyapatite granules [Manufactured by Universiti Sains Malaysia, (USM) Penang, Malaysia] in the bone marrow cells of mice. The mitotic indices of the groups treated with synthetic hydroxyapatite granules did not show any significant difference as compared to the negative control group treated with distilled water. Also the groups of mice treated with synthetic hydroxyapatite granules and distilled water did not induce significant change in chromosome aberrations as compared to the positive control group treated with Mitomycin C. The mitotic indices and chromosomal analyses indicate that under the present test conditions, synthetic hydroxyapatite granules (manufactured by USM) are non cytotoxic and do not induce chromosome aberrations in the bone marrow cells of mice.

Background: The Diabetes Mellitus in the OffspringQuestionnaire (DMOQ) assesses the perceptions of Type 2diabetes mellitus (T2DM) patients on the risk of theiroffspring developing T2DM and the possibility ofintervention to reduce this risk. It has 34 items framed withinseven domains. This study aimed to adapt, translate andvalidate the DMOQ from English into the Malay language.Methods: This was a cross-sectional validation study among159 T2DM patients attending a public primary care clinic inSelangor. The DMOQ English version underwent adaptation,translation, face validation and field testing to produce theMalay version. Psychometric analysis was performed usingExploratory Factor Analysis, internal consistency and testretestreliability.Results: The DMOQ domains were conceptually equivalentbetween English and Malay language. A total of 13 items andtwo domains were removed during the validation process(three items during the content validation, three items due topoor factor loadings, five items as they loaded onto twodomains which were not interpretable, one item as it did notfit conceptually into the factor it loaded onto and one openendedquestion as it did not fit into the retained domains).Therefore, the final DMOQ Malay version consisted of 21-items within five domains. The Cronbach alpha was 0.714and the intraclass-correlation coefficient was 0.868.Conclusion: The DMOQ Malay version is a valid and reliabletool which is consistent over time. It can be used to examinethe perception of T2DM patients towards the risk of theiroffspring developing diabetes and possibility of interventionin Malay-speaking patients.

Clival chordoma is a rare malignant tumor of the brain that typically occurs in older adults. It has a high local recurrence rate and is hence associated with poor prognosis. Here, we report a case of an adolescent who presented with a 1-month history of worsening headache and blurring of vision, as well as a 6-month history of left-sided facial and body numbness. Clinical findings were consistent with left upper motor neuron lesion of the seventh cranial nerve with involvement of the fifth cranial nerve. He was also found to have a sixth cranial nerve palsy demonstrated by diplopia upon lateral gaze with no evidence of papilledema. Magnetic resonance imaging of the brain suggested clival chordoma. He was subsequently referred to the neurosurgical team, and he successfully underwent an endoscopic trans-sphenoidal surgery to excise the lesion. He recovered well, continued his follow-ups with the neurosurgical team, and showed good progress. He also attended regular follow-ups with his primary care physician to ensure ongoing psychosocial support and monitoring of his overall health status. This case demonstrates the importance of prompt identification and treatment of clival chordoma in an adolescent. Long-term follow-ups and shared care between primary and secondary care physicians are essential to monitor recurrence of tumor and to provide psychosocial support.

Introduction: The Patient Activation Measure (PAM) is one of the most extensively used, widely translated, and tested instruments worldwide in measuring patient activation levels in self-management. This study aimed to determine the validity and reliability of the PAM-13 Malay version among patients with Metabolic Syndrome (MetS) attending a primary care clinic.Methods: This work is a cross-sectional validation study among patients with MetS attending a university primary care clinic in Selangor. The PAM-13 Malay version underwent a validation process and field testing. Psychometric properties were examined using principal component analysis (PCA) with varimax rotation, scree plot, Monte Carlo simulation, internal consistency, and test-retest reliability analyses. Results: The content of the PAM-13 Malay version and the original version were conceptually equivalent. The questionnaire was refined after face validation by 10 patients with MetS. The refined version was then field-tested among 130 participants (response rate 89.7%). The Kaiser–Meyer– Olkin test was 0.767, and Bartlett’s test of sphericity was ≤0.001, indicating sampling adequacy. Two factors were identified and labeled as (1) Passive and Building Knowledge, and (2) Taking Action and Maintaining Behavior. These labels were chosen as they were conceptually consistent with the items representing the levels of activation in PAM-13. The validated PAM-13 Malay version consisted of 13 items, framed into two domains. The overall Cronbach’s α was 0.79, and the intraclass correlation coefficient was 0.45. Conclusions: The PAM-13 Malay version is valid, reliable, and fairly stable over time. This questionnaire can be used to evaluate the levels of activation among patients with MetS in primary care in Malaysia.

Introduction: Childhood anxiety is one of the common mental health problems in children. Untreated childhood anxiety will lead to a higher risk of developing mental health problems in adulthood. Thus, this study aimed to investigate the relationship between parental emotional styles and family values to anxiety level among primary school children. Methods: A cross-sectional study was conducted in a selected primary school in Kelantan, Malaysia. A set of questionnaires consisted of the Revised Child Anxiety and Depression Scale–Parents’ Report (RCADS-P 25), the Parental Emotional Style Questionnaire (PESQ), and the Asian Family Characteristics Scale (AFCS) was used for assessing anxiety, parental emotional styles, and family values, respectively. Data were collected via an online survey using Google Form, and were analysed using Multiple Linear Regression (MLR) to determine the factors associated with childhood anxiety. The significance value was set at p < 0.05. Results: A total of 150 parents of primary school children from the selected school was involved in this study. The majority of respondents were females (82.0%), married (94.7%), hold a degree (66.7%), and were working in the government sector (60.0%). Most of the respondents’ child were twelve years old (20.7%) and males (62%). Based on the MLR, emotional dismissing parental style (p = 0.025) and family values (p = 0.016) were significantly associated with anxiety in these children. Conclusion: Emotional dismissing parental style and family values were significant predictors of anxiety in primary school children. Future intervention research on childhood anxiety is needed.
