Introduction: The USM Pre-clinical medical students’ guidance and counselling needs questionnaire (USM-MS- GCN-Q) is an English-language guidance and counselling needs questionnaire which was developed specifically for pre-clinical medical students. The aim of this study is to highlight the construct validity of USM-MSGCN-Q among pre-clinical medical students. Methods: In June 2017, a cross-sectional study on 208 pre-clinical medical students was conducted in Universiti Sains Malaysia (USM). This self-administered USM-MSGNC-Q consisted of four constructs and 20 items with a 5-point Likert scale within each item. A confirmatory factor analysis was em- ployed to test the hypothesized measurement model. Results: The final measurement model fitted the data well. The four-factor model initially consisted of 20 items however, it was reduced to 18 items with the goodness of fit indices suggesting good model fit (RMSEA 0.89, GFI .915 and ChiSq/df 2.642). Internal consistency reliability (Cronbach’s alpha) was 0.879 for self-leadership skills, 0.929 for communication skills, 0.871 for learning skills, and 0.870 for psychological coping skills. The overall Cronbach’s value was 0.922. Respective composite reliability values were 0.879,0.952,0.879 and 0.835 while the Average Variance Extracted values were 0.729, 0.911, 0.595 and 0.630. Conclusion: This study has confirmed that self-leadership, communication, learning and psychological coping skills were the components of guidance and counselling needs which influences the effectiveness of guidance and coun- selling sessions with pre-clinical medical students.

Premature ejaculation (PE) reduces sexual satisfaction and quality of life.
Both SSRI Fluoxetine and Dapoxetine have been used in the treatment of PE. Fluoxetine
is used as off-label treatment meanwhile Dapoxetine is the first SSRI specifically
designed for PE with short half-life and few side effects. (Copied from article).

One of the challenges in mentoring relationships is to understand the real issues faced by the mentees. A mechanism has been established to offer a credible mentoring inventory. The aim of the study was to determine the construct validity and reliability index of the Universiti Sains Malaysia Mentoring Inventory (USM-MT-i) among early phase medical students in a Malaysian public medical school. A cross-sectional study was conducted in June 2017 among 208 early phase of the medical students of School of Medical Sciences, Universiti Sains Malaysia. USM-MT-i is a self-administered inventory and was established based on the information gained from the mentors and mentees. The prevalidated inventory entailed 44 primary items. Exploratory factor analysis (EFA) and Cronbach’s alpha reliability analysis were utilised to determine the construct validity and reliability of such inventory. The result revealed three potential constructs with 39 items extracted from the USMMT- i; academic leadership (19 items), communication skills (12 items) and examination competence (8 items) with factor loading ranges from 0.50–0.77, 0.51–0.80 and 0.65–0.87, respectively. Internal consistency reliability (Cronbach’s alpha) for each domain were 0.95, 0.93 and 0.92, respectively. The overall Cronbach’s alpha was 0.96. The present study promoted that the three factors with 39 items of the USM-MT-i has a good validity and reliability value to survey for mentoring needs among medical students in their early phase.

Background: In end-stage renal disease (ESRD), troponin T concentrations can be elevated even without cardiac ischaemia, which hampers the diagnosis of acute myocardial infarction (AMI). The objectives of our study were to determine the proportion of dialysisdependent ESRD patients without acute coronary syndrome (ACS) but with highly sensitive cardiac troponin T (hs-cTnT) levels above the 99th percentile upper reference limit and to evaluate the range of hs-cTnT among this population.
Methods: A cross-sectional study was conducted at the haemodialysis (HD) unit of a tertiary hospital in Malaysia from January 2018 to February 2019. Dialysis-dependent ESRD patients were included and those with a recent history of ACS (within 30 days) were excluded. Pre-dialysed serum hs-cTnT levels were measured using Cobas e411. The upper limit of the 99th percentile value for troponin T was 14 ng/L.
Results: A total of 150 patients were recruited as study participants. The majority were female (62%) and of Malay ethnicity (94%), and the mean (SD) age was 45.19 (16.36) years old. The hs-cTnT range (min, max) was 11.39-738.30 ng/L and the median (interquartile range [IQR]) of hs-cTnT was 59.20 (83.41) ng/L. Elevated hs-cTnT levels were observed in 149/150 (99%) of the study participants (54/55 [98.2%] of the patients were on HD, and 95/95 [100.0%] of the patients were on continuous ambulatory peritoneal dialysis).
Conclusion: This study supports prior research showing that even without ACS, most ESRD patients have elevated concentrations of cardiac troponin. Furthermore, our study illustrates the need to revisit the use of absolute troponin values when making a diagnosis of ACS in ESRD patients.
