Depression and anxiety are common complications associated with traumatic brain injury (TBI) patients but screening tools which are validated to assess these complications in the TBI population are scarce. This study investigated the validity of the Malay version of Hospital Anxiety and Depression Scale (HADS) to screen for depression and anxiety among Malaysian TBI patients. Materials and Methods: This cross-sectional study recruited 101 TBI patients in which they were administered the Malay version of HADS and the Structured Clinical Interview for Diagnostic and Statistical Manual for Mental Disorder 4thEdition (DSM-IV) for Axis I Disorders (SCID-I) (as comparison tool). Internal consistency (Cronbach’s α) and concurrent validity (using receiver operating characteristics) of the Malay version of HADS were evaluated. Results: The total Malay version of HADS score and its anxiety subscale exhibited good internal consistency of 0.80 and 0.78 respectively, but the internal consistency of its depressive subscale was low at 0.57. The depressive subscale of the Malay version of HADS exhibited high area under the curve (AUC) of 0.86, specificity of 82%, sensitivity of 76% and negative predictive value of 91% but its positive predictive value was 58%, at cut-off point of 8/9. While the anxiety subscale also demonstrated high AUC of 0.88, specificity of 71%, sensitivity of 93% and negative predictive value of 98% its positive predictive value was only 34%. Conclusion: The Malay version of HADS is a valid screening tool for depression and anxiety among Malaysian TBI population.

Brain-derived neurotrophic factor (BDNF) is a neurotrophin that is highly expressed in the brain. It influences neuronal survival, growth and acts as a control centre for neurotransmitters. It also plays a crucial role in learning and memory. Current evidence indicates that BDNF may be a possible neurotrophic factor that controls cognitive functions under normal and neuropathological conditions. Recent findings indicate a reduction in cognitive performance in individuals with Alzheimer's disease (AD). This relationship between cognitive performance and AD is important for investigating both the time they overlap and the pathophysiological mechanism in each case. Therefore, this study reviewed the existing knowledge about BDNF and cognitive performance in the AD population. The findings support the idea that this tropic factor may be a potential biomarker for evaluating the changes in cognitive performance in AD.

Objectives: Posttraumatic growth (PTG) is the experience of positive psychological growth as a result of struggle with highly challenging life crises. This study was conducted to investigate the degree of PTG and its associated factors, as well as to identify which positive psychological parameters most significantly associated with greater PTG among Malaysian cancer patients. Design, sample, & methods: This cross-sectional survey included 195 patients with different cancer diagnoses. Perceived spousal support, level of hope, level of optimism, and PTG were measured using various validated indexes. Findings: The total mean score for PTG Inventory-Short Form (PTGI-SF) was 39.87 (±9.09). Female gender, Islamic religious belief, and having higher level of hope and greater spousal support were associated with a higher PTGI-SF score, and the most significant predictor was the hope scale. Conclusions: Malaysian cancer patients exhibited a high level of PTG, and hope was the positive psychological factor which was most significantly associated with PTG. Implications for psychosocial providers: Psychosocial interventions that promote positive psychology should be included in the treatment for cancer patients.
Is kratom (Mitragyna speciosa Korth.) use associated with ECG abnormalities? Electrocardiogram comparisons between regular kratom users and controls

OBJECTIVES: Little is known about the cardiotoxic effects of kratom (Mitragyna speciosa Korth.), a medicinal plant. This analytical cross-sectional study investigated the prevalence of electrocardiogram (ECG) abnormalities and QTc intervals in regular kratom users compared with non-kratom-using control subjects.
METHODS: We enrolled regular kratom users and non-kratom-using control subjects from three communities. Demographic data, clinical data, kratom use characteristics, and ECG findings were recorded. The mitragynine content of kratom juice was quantified using a validated gas chromatography-mass spectrometry (GC-MS) method.
RESULTS: A total of 200 participants (100 kratom users and 100 control subjects) participated in this study. The prevalence of ECG abnormalities in kratom users (28%) did not differ from that of control subjects (32%). Kratom use was not associated with ECG abnormalities, except for significantly higher odds of sinus tachycardia (OR = 8.61, 95% CI = 1.06-70.17, p = 0.035) among kratom users compared with control subjects. The odds of observing borderline QTc intervals were significantly higher for kratom users compared with control subjects, regardless of the age of first use, the duration of use, the daily quantity consumed, and the length of time that had elapsed between last kratom use and ECG assessment. Nevertheless, there were no differences in the odds of having prolonged QTc intervals between kratom users and controls. The estimated average daily intake of mitragynine consumed by kratom users was 434.28 mg.
CONCLUSION: We found no link between regular kratom use and electrocardiographic abnormalities with an estimated average daily intake of 434.28 mg of mitragynine.
