Mentoring in academic medicine requires the trained mentor to commit time, purpose and dedication for the personal and professional development of three categories of protégés or mentees i.e. medical students, the clinician-trainee and the clinical-educator. Conventionally, assigned mentors monitor the progress of the first two categories of personnel as their career pathway is clearly defined. On the other hand the clinician–educator in academic medicine could be a scientist or a career clinician expected to contribute to medical education activities and research. The clinician educator has grown in complexity as he multitasks in providing clinical care, assists in delivering the medical curriculum and is expected to do research and publish. Although there is dearth of research in mentoring the clinician-educator, it is clear that mentored clinicaleducators are more productive by way of scientific publications. Trained mentors are expected to identify the needs of the mentee with regards to the level of his career development and his aptitude to move up the academic ladder, successfully nurturing the maturation process. Processes of mentoring in the clinical setting, attributes of the successful mentor and facilitating the mentee in overcoming challenges in academic medicine are discussed.

Fulltext Information-seeking practices of senior medical students: the impact of an evidence-based medicine training programme

Lai NM, Nalliah S

Educ Health (Abingdon), 2010 Apr;23(1):151.
PMID: 20589599

CONTEXT: The practice of Evidence-based Medicine (EBM) involves physicians regularly accessing and appraising clinical information. Few prior studies have assessed the information-seeking behaviours of medical undergraduates. At the International Medical University (IMU), Malaysia, senior medical students receive clinically-integrated EBM training to facilitate their future practice of EBM.
OBJECTIVES: We assessed whether EBM training in the final six months of medical training changes our students' information-seeking practices and their confidence in understanding and appraising clinical evidence.
METHODS: Between September 2005 and February 2006, self-administered questionnaires were distributed to 65 senior medical students at the beginning and again at the end of their clerkship training during which there was a clinically-integrated EBM curriculum. The questionnaires covered the topics of their preferred sources of clinical information, online search frequencies, estimated time to retrieve an abstract, and their understanding and confidence in their critical appraisal skills.
FINDINGS: Sixty-four (98%) students completed the initial survey and 63 (97%) completed the follow-up survey. The majority indicated that they preferred to first consult another individual (colleagues, lecturers, hospital staff) for their clinical queries (60.9% in the initial survey and 61.9% in the follow-up survey), with no change in their overall preference following the EBM curriculum six months later (p=0.144). There were significant increases in search activities following the curriculum, for example, students who searched PubMed or Medline for more than three times per week increased from 9.7% to 31.7% (p < 0.001). Students reported that they more often accessed single journals than databases. Despite significant improvements in students' reported understanding of journals and their confidence in critical appraisal (p < 0.001), there was no improvement in reported search speed, with 48.4% in the initial survey and 49.2% in the follow-up survey reporting to take 30 minutes or less to trace an abstract of interest (p=0.979).
CONCLUSIONS: Our EBM training, offered within a supportive curriculum, increased our students' confidence and activity related to EBM, but failed to change students' reported information-seeking behaviours. Other factors influencing medical students' information-seeking practice need to be explored.

Fulltext Eclampsia in Kelantan

Nalliah S, Abdullah AR

Med J Malaysia, 1990 Mar;45(1):49-56.
PMID: 2152069

A review of eclampsia in Kelantan was undertaken from 1983-1988. There were 146 documented cases in the state (66 per 100,000 deliveries). Eight maternal deaths occurred. Sixty seven (45.9%) were primigravida. Six of the 79 multiparous women developed eclampsia for the first time following remarriages to new partners. The multisystem dysfunction resulting from eclampsia resulted in varied maternal complications. Fatal cerebral haemorrhage (3 cases), acute pulmonary oedema (8 cases), acute renal failure (6 cases), HELLP Syndrome (8 cases) and acute abruptio placentae were the commoner complications. The average number of convulsions per patient was 1.3. The mean gestation of mothers who delivered prematurely (28.2%) was 34.6 weeks and that for those at term (71.8%) was 39.1 weeks. The caesarean section rate was 42.5%. The perinatal mortality rate was 185.9 per 1000. The implications of this high maternal and fetal mortality and morbidity are discussed in the light of the health delivery system and patient education. A team approach to medical management of eclampsia with the need for intensive care monitoring is suggested.

Nalliah S, Thavarashah AS

Int J Gynaecol Obstet, 1989 Jul;29(3):249-51.
PMID: 2569423

Transient blindness associated with pregnancy induced hypertension without neurological symptoms is a rare phenomenon. The blindness in these cases is postulated to be of "cortical blindness". Two such cases occurring immediately after childbirth are presented. The ophthalmic manifestations of this complication of pregnancy induced hypertension and the importance of an urgent evaluation are discussed.
Is menopause managed well enough in general practice?

Thuraisingham C, Nalliah S

Malays Fam Physician, 2023;18:49-100.
PMID: 37719692 DOI: 10.51866/cm.264

Menopause is an important phase in the life of older women. Women's life expectancy has increased worldwide. As women experience and perceive menopause differently depending on their personal, family and sociocultural backgrounds, perimenopausal symptoms can often go unnoticed and missed by general practitioners. General practitioners are uniquely placed in the healthcare delivery pyramid to close this gap and improve patients' quality of life by identifying perimenopausal signs and symptoms early. This article shares knowledge about continuing medical education for general practitioners to close the existing gap. As there is great variability within each menopausal woman's experience as well as among individual women, there is a need to individualise and render personalised care. By being able to discuss accepted and safe standards of care and by advocating for a holistic approach incorporating both non-pharmacological and pharmacological strategies, general practitioners would be able to improve the confidence of their patients for better health outcomes.

The reliability and relevance of medical literature are significant concerns in the post-COVID-19 era, where misinformation and disinformation are serious threats. This practice guide provides an overview of practical strategies to appraise the reliability of research publications critically. These strategies include critically appraising the effectiveness and constraints of various approaches to disseminating medical information, choosing appropriate medical literature resources, navigating library databases, screening the literature from the search, and screening individual publications. We also discuss the importance of considering study limitations and the relevance of the results in research or use in the medical arena. In-depth, critical appraisal of medical or clinical research evidence requires expertise, insight into research methodologies, and a grasp of issues in each field. By harnessing the wealth of reliable and relevant information available in medical literature through the above steps, we can alleviate potentially misleading information and stay at the forefront of our respective fields.
Online formative assessments: exploring their educational value

Nagandla K, Sulaiha S, Nalliah S

J Adv Med Educ Prof, 2018 Apr;6(2):51-57.
PMID: 29607332

Introduction: Online formative assessments (OFA's) have been increasingly recognised in medical education as resources that promote self-directed learning. Formative assessments are used to support the self-directed learning of students. Online formative assessments have been identified to be less time consuming with automated feedback. This pilot study aimed to determine whether participation and performance in online formative assessments (OFA's) had measurable effects on learning and evaluate the students' experience of using the OFA's in the department of Obstetrics and Gynaecology.
Methods: This is a cross-sectional study conducted among fourth year medical students (n=92) during their seven week postings in Obstetrics and Gynaecology. Five sets of online formative assessments in the format of one best answers (OBA), Objective structured practical examination (OSPE) and Short answer question (SAQ) with feedback were delivered over five weeks through the online portal. The mean scores of the end of posting summative exam (EOP) of those who participated in the assessments (OFA users) and of those who did not (non-OFA users) were compared, using Students t test. The frequency of tool usage was analysed and satisfaction surveys were utilized at the end of the course by survey questionnaire using the five point Likert scale.
Results: The mean scores of the students in end of posting summative examination marks for students who had participated in the online formative assessment (OFA users) and for those who had not (non OFA users) showed no significant difference in all the three components OBA, SAQ and OSPE (p=0.902, 0.633, 0.248). Majority of the students perceived that OFAs fulfilled the stated aims and objectives and so they would persuade their peers to participate in the OFAs.
Conclusions: Online formative assessments are perceived as tools that promote self-directed learning, improved knowledge and tailor learning for individual learning needs and style.
Fulltext Assessing undergraduate competence in evidence based medicine: a preliminary study on the correlation between two objective instruments

Lai NM, Teng CL, Nalliah S

Educ Health (Abingdon), 2012 Jul;25(1):33-9.
PMID: 23787382

CONTEXT: The Fresno test and the Berlin Questionnaire are two validated instruments for objectively assessing competence in evidence-based medicine (EBM). Although both instruments purport to assess a comprehensive range of EBM knowledge, they differ in their formats. We undertook a preliminary study using the adapted version of the two instruments to assess their correlations when administered to medical students. The adaptations were made mainly to simplify the presentation for our undergraduate students while preserving the contents that were assessed.
METHODS: We recruited final-year students from a Malaysian medical school from September 2006 to August 2007. The students received a structured EBM training program within their curriculum. They took the two instruments concurrently, midway through their final six months of training. We determined the correlations using either the Pearson's or Spearman's correlation depending on the data distribution.
RESULTS: Of the 120 students invited, 72 (60.0%) participated in the study. The adapted Fresno test and the Berlin Questionnaire had a Cronbach's alfa of 0.66 and 0.70, respectively. Inter-rater correlation (r) of the adapted Fresno test was 0.9. The students scored 45.4% on average [standard deviation (SD) 10.1] on the Fresno test and 44.7% (SD 14.9) on the Berlin Questionnaire (P = 0.7). The overall correlation between the two instruments was poor (r = 0.2, 95% confidence interval: -0.07 to 0.42, P = 0.08), and correlations remained poor between items assessing the same EBM domains (r = 0.01-0.2, P = 0.07-0.9).
DISCUSSION: The adapted versions of the Fresno test and the Berlin Questionnaire correlated poorly when administered to medical students. The two instruments may not be used interchangeably to assess undergraduate competence in EBM.
Fulltext Is there a genetic variation association in the IL-10 and TNF alpha promoter gene with gestational diabetes mellitus?

Montazeri S, Nalliah S, Radhakrishnan AK

Hereditas, 2010 Apr;147(2):94-102.

Gestational diabetes mellitus (GDM), defined as carbohydrate intolerance diagnosed for the first time during pregnancy, affects both maternal and fetal health. Possession of a specific genetic polymorphism can be a predisposing factor for susceptibility to some diseases. The aim of this study was to investigate the association between single nucleotide polymorphisms (SNP) in the promoter gene of interleukin-10 (IL-10) as well as tumor necrosis factor-alpha (TNF alpha) with the development of GDM. Two hundred and twelve consecutive series of eligible normal pregnant women (controls) and gestational diabetes mellitus women were selected based on the study's inclusion and exclusion criteria. DNA was extracted from blood and genotyped for IL-10 at three positions and TNF alpha for gene polymorphism using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Plasma levels of IL-10 and TNF alpha at different gestational periods as well as postpartum were quantified using enzyme linked immunosorbent assay (ELISA). The results of the study showed that the difference in the frequency of SNP at position -597 in the promoter of the human IL-10 gene between the control and GDM groups was statistically significant (p < 0.05). In contrast, there was no significant difference in the frequency of SNP at the other two sites in the promoter region of the human IL-10 gene (-824 and -1082) as well as position -308 in the promoter of the human TNF-alpha (p > 0.05). In addition, there was no significant difference between the two groups in terms of plasma levels of IL-10 as well as TNF alpha in different stages of pregnancy. SNP at position -597 was significantly associated with the development of GDM and shows potential for use as a predictive marker for GDM.
Association between polymorphisms in human tumor necrosis factor-alpha (--308) and -beta (252) genes and development of gestational diabetes mellitus

Montazeri S, Nalliah S, Radhakrishnan AK

Diabetes Res Clin Pract, 2010 May;88(2):139-45.
PMID: 20189261 DOI: 10.1016/j.diabres.2010.01.028

OBJECTIVE: The aim of this study is to investigate if an association exists between single nucleotide polymorphism (SNP) in the tumor necrosis factor-alpha (TNF-alpha) and TNF-beta genes.
METHODS: The DNA was extracted and SNP in the human TNF-alpha and TNF-beta genes at positions -308 (G/A) and 252 (A/G), respectively, was analyzed using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Plasma levels of TNF-alpha in different stages of pregnancy were quantified using enzyme linked immunosorbent assay (ELISA).
RESULTS: There was no significant difference in genotype and allele frequency of SNP at position -308 (G/A) in the promoter region of the human TNF-alpha gene as well as the SNP at position 252 (A/G) in the human TNF-beta gene between the GDM and control subjects. Using the logistic regression model, it was found that the SNP in the TNF-alpha as well as TNF-beta were not associated with development of GDM. In addition, the TNF-alpha levels in the plasma of GDM and control mothers were not significantly different.
CONCLUSIONS: In the population studied, the SNP in position -308 (G/A) of the human TNF-alpha or in position 252 (A/G) of the human TNF-beta gene is not an independent risk factor or a predictor for GDM.
Fulltext Multifaceted usage of HPV related tests and products in the management of cervical cancer--a review

Nalliah S, Karikalan B, Kademane K

Asian Pac J Cancer Prev, 2015;16(6):2145-50.
PMID: 25824730

HPV viruses are integral to the development of cervical cancer. The pathogenesis has been extensively studied. To date, numerous HPV tests and products have been developed and successfully utilized in diagnosis, treatment and prevention of cervical cancer. The HPV DNA test, when combined with other routine cervical cancer screening and diagnostic tests namely exfoliative cytology, visual inspection with acetic acid (VIA) and colposcopy has increased the detection rate of cervical cancer. HPV DNA products could also be measured in other body fluids like urine, lymph node tissue, and serum. HPV association could also be quantified by measuring other parameters like HPV mRNA, viral load, viral integration and methylation status. Vaccination against HPV has been found to decrease the incidence of cervical cancer. Further, therapeutic vaccines for cervical cancer against HPV continue to evolve. All these findings pertaining to HPV could possibly decrease the incidence of cervical cancer in the near future. This review aims to give an overview of the HPV tests and products in use and those under trial currently.

Cervical pessary in the prevention of preterm births in multiple pregnancies with a short cervix: PRISMA compliant systematic review and meta-analysis

Thangatorai R, Lim FC, Nalliah S

J Matern Fetal Neonatal Med, 2018 Jun;31(12):1638-1645.
PMID: 28412851 DOI: 10.1080/14767058.2017.1319930

BACKGROUND: Preterm births occur frequently in multiple pregnancies with a short cervix. The cervical pessary is a potential intervention for prevention of preterm births.
OBJECTIVE: To assess the effectiveness of cervical pessary in the prevention of preterm births in multiple pregnancies with a short cervix (<25 mm).
SEARCH STRATEGY: Major databases from 2006 to 20th November 2016 were searched for relevant terms.
SELECTION CRITERIA: We included randomized controlled trials that assessed the effectiveness of cervical pessary on pregnancy outcomes in multiple pregnancies with a short cervix.
DATA COLLECTION AND ANALYSIS: Risk ratio was used as the summary measure with random effects model. We assessed heterogeneity between studies using the I2 index. Quality assessment was done based on Cochrane Handbook Method.
MAIN RESULTS: Pooled data showed no benefit of using cervical pessary in the prevention of preterm births, birth weights less than 1500 g, less than 2500 g, adverse neonatal events and fetal/neonatal deaths in twin pregnancies with a short cervix.
CONCLUSION: We are unable to show benefit of using cervical pessary in preventing preterm births in twin pregnancies with a short cervix. However, as cervical pessary is a reasonable intervention, there is a need for more randomized controlled trials in this area.
The educational environment and self-perceived clinical competence of senior medical students in a Malaysian medical school

Lai N, Nalliah S, Jutti RC, Hla Y, Lim VK

Educ Health (Abingdon), 2009 Aug;22(2):148.
PMID: 20029744

The educational environment is widely considered to be a major factor affecting students' motivation and learning outcomes. Although students' perceptions of their educational environment are often reported, we are unaware of any published reports that relate this information to students' clinical competence, either self-perceived or objectively measured.
