    AIM: Calcium infusion is used after parathyroid surgery for renal hyperparathyroidism to treat postoperative hypocalcaemia. We compared a new infusion regimen to one commonly used in Malaysia based on 2003 K/DOQI guidelines.

    METHODS: Retrospective data on serum calcium and infusion rates was collected from 2011-2015. The relationship between peak calcium efflux (PER) and time was determined using a scatterplot and linear regression. A comparison between regimens was made based on treatment efficacy (hypocalcaemia duration, total infusion amount and time) and calcium excursions (outside target range, peak and trough calcium) using bar charts and an unpaired t-test.

    RESULTS: Fifty-one and 34 patients on the original and new regimens respectively were included. Mean PER was lower (2.16 vs 2.56 mmol/h; P = 0.03) and occurred earlier (17.6 vs 23.2 h; P = 0.13) for the new regimen. Both scatterplot and regression showed a large correlation between PER and time (R-square 0.64, SE 1.53, P

    Currently, protein interaction of Homo sapiens nucleotide binding domain (NBD) of heat shock 70 kDa protein (PDB: 1HJO) with p53 motif remains to be elucidated. The NBD-p53 motif complex enhances the p53 stabilization, thereby increasing the tumor suppression activity in cancer treatment. Therefore, we identified the interaction between NBD and p53 using STRING version 9.1 program. Then, we modeled the three-dimensional structure of p53 motif through homology modeling and determined the binding affinity and stability of NBD-p53 motif complex structure via molecular docking and dynamics (MD) simulation. Human DNA binding domain of p53 motif (SCMGGMNR) retrieved from UniProt (UniProtKB: P04637) was docked with the NBD protein, using the Autodock version 4.2 program. The binding energy and intermolecular energy for the NBD-p53 motif complex were -0.44 Kcal/mol and -9.90 Kcal/mol, respectively. Moreover, RMSD, RMSF, hydrogen bonds, salt bridge, and secondary structure analyses revealed that the NBD protein had a strong bond with p53 motif and the protein-ligand complex was stable. Thus, the current data would be highly encouraging for designing Hsp70 structure based drug in cancer therapy.

    In recent years, there have been increasing accounts of illegal substance abuse among university students and professional groups in Malaysia. This study looks at university students' perceptions about this phenomenon. Students from Malaysian universities were asked for their impressions about drug availability and abuse, as well as factors contributing to drug abuse and relapse. The questionnaire also inquired into their knowledge and views regarding government versus private rehabilitation centers, as well as their exposure to, and views about, school-based drug-prevention education. Participants were 460 university students from five Malaysian states: Penang, Selangor, Kuala Lumpur, Sabah, and Sarawak. Results showed gender differences in perceptions of relapse prevention strategies, as well as factors leading to drug abuse and relapse. Students also believed that drug education would be more effective if initiated between the ages of 11 and 12 years, which is slightly older than the common age of first exposure, and provided suggestions for improving existing programs. Implications of student perceptions for the improvement of current interventions and educational programs are discussed.

    Introduction:The incidence of pertussis has been said to increase over the years, and the affected patient-age group has also changed with the increasing number of cases amongst adolescents and adults. Therefore, adults require booster vaccination for protection against pertussis infection. Vaccination among healthcare workers (HCW) should be prioritized when a country implements an adult vaccine. However, the coverage of pertussis vaccination is still deficient among HCW due to low-risk perception. This study focused on finding the risk perception of pertussis in-fection amongst the HCWs based on the Protection Motivation Theory (PMT) and their acceptance to take pertussis vaccination. Methods: This was a cross-sectional study using online survey. The website link is given to the Health-care workers consisting of doctors, Assistant Medical Officers, nurses, and Environmental Health Officers. Results: A total of 853 responders responded to the questionnaire. Most of the respondents (81.5%) are willing to receive the pertussis vaccine. Independent t-test showed that the PMT score was significantly different between those willing and those not willing to take the vaccine (p-value < 0.001, t statistics (df)= 7.729 (325). Robust path analysis showed that sociodemographic factors (age, the institution of working and prior pertussis vaccination) (p=0.004), threat (p

    Halophiles are extremophilic microorganisms that grow optimally at high salt concentrations by producing a myriad of equally halotolerant enzymes. Structural haloadaptation of these enzymes adept to thriving under high-salt environments, though are not fully understood. Herein, the study attempts an in silico investigation to identify and comprehend the evolutionary structural adaptation of a halotolerant dehalogenase, DehHX (GenBank accession number: KR297065) of the halotolerant Pseudomonas halophila, over its non-halotolerant counterpart, DehMX1 (GenBank accession number KY129692) produced by Pseudomonas aeruginosa. GC content of the halotolerant DehHX DNA sequence was distinctively higher (58.9%) than the non-halotolerant dehalogenases (55% average GC). Its acidic residues, Asp and Glu were 8.27% and 12.06%, respectively, compared to an average 5.5% Asp and 7% Glu, in the latter; but lower contents of basic and hydrophobic residues in the DehHX. The secondary structure of DehHX interestingly revealed a lower incidence of α-helix forming regions (29%) and a higher percentage of coils (57%), compared to 49% and 29% in the non-halotolerant homologues, respectively. Simulation models showed the DehHX is stable under a highly saline environment (25% w/v) by adopting a highly negative-charged surface with a concomitant weakly interacting hydrophobic core. The study thus, established that a halotolerant dehalogenase undergoes notable evolutionary structural changes related to GC content over its non-halotolerant counterpart, in order to adapt and thrive under highly saline environments.Communicated by Ramaswamy H.

    Objective: This study assesses the prevalence of musculoskeletal (MSK) pain in patients attending primary care clinics in a medium-sized town in Malaysia and examines the interventions given for the symptoms and the level of the associated disabilities.

    Method: This investigation comprises a cross-sectional descriptive study of all patients visiting two primary care clinics aged 18 years and above. Patients presenting with joint pain answered a questionnaire assessing demographic data, disabilities (measured by the Stanford HAQ-DI), and treatment options.

    Results: Of 1,074 patients surveyed, 202 (18.8%) had MSK complaints. The mean age of those with MSK pain was 56.1 years. Incidence increased with age, reaching 78.8% of those over 48 years of age. The knee was the most common site of MSK pain (52.2%), with 20.3% requiring referral for specialist assessment. The median HAQ score was 0.375 and 89.6% of those surveyed had mild disability.

    Conclusion: MSK pain is a common problem among patients visiting primary care clinics. The most common site of MSK pain was the knee. On formal assessment, the majority of these patients exhibited mild disability. A significant proportion of patients still required specialist referral. This finding would suggest a need for further training on the management of MSK disease at the primary care level to avoid over-burdening the secondary care services.

    Next generation DNA sequencing and analysis of amplicons spanning the pharmacogene CYP2D6 suggested that the Nextera transposase used for fragmenting and providing sequencing priming sites displayed a targeting bias. This manifested as dramatically lower sequencing coverage at sites in the amplicon that appeared likely to form G-quadruplex structures. Since secondary DNA structures such as G-quadruplexes are abundant in the human genome, and are known to interact with many other proteins, we further investigated these sites of low coverage. Our investigation revealed that G-quadruplex structures are formed in vitro within the CYP2D6 pharmacogene at these sites, and G-quadruplexes can interact with the hyperactive Tn5 transposase (EZ-Tn5) with high affinity. These findings indicate that secondary DNA structures such as G-quadruplexes may represent preferential transposon integration sites and provide additional evidence for the role of G-quadruplex structures in transposition or viral integration processes.

    BACKGROUND: This preliminary finding from a qualitative study examined the process of self-efficacy for the development of physical activity during myocardial infarction (MI) after recovery. A combination of healthy behaviors, including physical activity is the secondary prevention recommended to reduce the risk of recurrent MI. This study aims to understand how self-efficacy for physical activity is developed in a patient after MI by examining their perceptions and personal adherence to physical activity.

    DESIGN AND METHODS: This was a qualitative study and data was collected through semi-structured in-depth recorded phone interviews with eight Malay male participants. They were screened using a questionnaire and participants that met the inclusion criteria were interviewed, and were admitted to National Heart Centre, Malaysia between January to June 2019 diagnosed with MI. The data collected were analysed using NVivo 12 software and thematic analysis was applied.

    RESULTS: Four preliminary themes emerged from the study: 1) beliefs in physical activity; 2) healthy lifestyle: new normal or same old habit; 3) factors determining participation in pa; and 4) physical activity adherence strategies.

    CONCLUSIONS: The results of the studies showed that participants understand the need to maintain physical activity, which helps to maintain a healthy life after MI and prevent recurrent infarction. Strategies for developing self-efficacy for physical activity were also discussed. The need to understand that maintaining physical activity as well as adopting a new normal of healthy habit after MI is crucial in order to maintain the health and prevent recurrence of MI.

    INTRODUCTION: Most of the authors currently agree that congenital talipes equinovarus (CTEV) or idiopathic clubfoot can be effectively treated with the Ponseti method instead of extensive soft tissue surgery. This study was conducted to investigate whether there is a difference in the outcome between starting treatment before one month of age or after that age.

    METHODS: This is a retrospective study on babies with CTEV treated in University Malaya Medical Centre from 2013 to 2017. The 54 babies (35 boys and 19 girls) were divided into two cohorts, Group 1 that had treatment before the age of one month, and Group 2 that had treatment after one month old. The number of cast changes, rate of full correction, and rate of relapse after treatment were compared between the two groups.

    RESULTS: Of the 54 babies, with 77 CTEV treated during the period, our outcome showed that the mean number of cast change was 5.9 for Group 1 and 5.7 for Group 2. The difference was not statistically significant. All the affected feet (100%) achieved full correction. One foot in the Group 1 relapsed, while three feet in Group 2 relapsed, but the difference was also not statistically significant. All of the relapsed feet were successfully treated with repeated Ponseti method.

    CONCLUSIONS: Treating CTEV using Ponseti method starting after one month was not associated with more casting change of higher rate of relapse.

    Stroke is a key cerebrovascular disease that is related to high morbidity and mortality in the globe. The Kingdom of Saudi Arabia (KSA) is not an exception where stroke is fast developing into a serious challenge due to the high mortality rate. Additionally, stroke presents a tremendous economic burden and has a devastating effect on the quality of lives of individuals. The number of stroke cases are increasing yearly, thus posing a major challenge to the health care system. Therefore, it is crucial to implement primary and secondary prevention strategies in the KSA. Nevertheless, as compared with developed countries, information on the prevalence, socio-demographic properties and prevention of stroke remains scarce that could be attributed to the shortage of research conducted in this specified region. The review is written to address the various aspects of stroke in the KSA, based on current literatures search using PubMed, Scopus, Web of Science and Google Scholar databases, to identify studies published since inception to Dec 2020.

    The current review aims to summarise the biodiversity and biosynthesis of novel secondary metabolites compounds, of the phylum Actinobacteria and the diverse range of secondary metabolites produced that vary depending on its ecological environments they inhabit. Actinobacteria creates a wide range of bioactive substances that can be of great value to public health and the pharmaceutical industry. The literature analysis process for this review was conducted using the VOSviewer software tool to visualise the bibliometric networks of the most relevant databases from the Scopus database in the period between 2010 and 22 March 2021. Screening and exploring the available literature relating to the extreme environments and ecosystems that Actinobacteria inhabit aims to identify new strains of this major microorganism class, producing unique novel bioactive compounds. The knowledge gained from these studies is intended to encourage scientists in the natural product discovery field to identify and characterise novel strains containing various bioactive gene clusters with potential clinical applications. It is evident that Actinobacteria adapted to survive in extreme environments represent an important source of a wide range of bioactive compounds. Actinobacteria have a large number of secondary metabolite biosynthetic gene clusters. They can synthesise thousands of subordinate metabolites with different biological actions such as anti-bacterial, anti-parasitic, anti-fungal, anti-virus, anti-cancer and growth-promoting compounds. These are highly significant economically due to their potential applications in the food, nutrition and health industries and thus support our communities' well-being.

    Esophageal cancer is one of the top leading causes of cancer-related deaths in Malaysia. To date, neither the prevalence nor incidence of esophageal cancer nationally have been recorded. Esophageal cancer remains a major and lethal health problem even if it is not common in Malaysia. The late presentation of esophageal cancer makes it a difficult and challenging medical problem. Therefore, more governmental and non-governmental organizations of Malaysia should emphasize primary and secondary prevention strategies.

    Rapid epidemiological transition globally has witnessed a rising prevalence of major chronic diseases such as hypertension, diabetes, hyperlipidaemia, obesity, chronic respiratory diseases and cancers over the past 30 years. In Malaysia, these conditions are commonly managed in primary care and published evidence has consistently shown suboptimal management and poor disease control. This in turn, has led to the massive burden of treating complications in secondary care, burden to the patients and their families with regards to morbidity and premature death, and burden to the country with regards to premature loss of human capital. The crushing burden and escalating health care costs in managing chronic diseases pose a daunting challenge to our primary care system, as we remain traditionally oriented to care for acute, episodic illnesses. This paper re-examines the current evidence supporting the implementation of Wagner Chronic Care Model in primary care globally; analyses the barriers of implementation of this model in the Malaysian private general practice through SWOT (strengths, weaknesses, opportunities and threats) analysis; and discusses fundamental solutions needed to bridge the gap to achieve better outcomes.

    Primary care practice with its defining features of continuity, comprehensiveness and coordination, is the cornerstone to provide high quality community-based chronic disease management. Poor chronic disease prevention and control at the primary care level will lead to the massive burden of treating complications at secondary care, burden to the patients and their families with regards to morbidity and premature death, and burden to the country with regards to the loss of human capital. Compelling evidence showed that there are innovative and cost-effective interventions to reduce the morbidity and mortality attributable to chronic diseases, but these are rarely translated into high quality population-wide chronic disease care. Primary health care systems around the world were developed in response to acute problems and have remained so despite the increasing prevalence of chronic conditions. An evolution of primary health care system beyond the acute care model to embrace the concept of caring for long term health problems is imperative in the wake of the rising epidemic of chronic diseases. This paper aims to review the evidence supporting high quality and innovative chronic disease management models in primary care and the applicability of this approach in low and middle income countries.

    In pregnancy, the diagnosis of primary hyperparathyroidism (PHP) may be delayed due to physiological changes that occur during this period. The maternal related complications of PHP during pregnancy has been reported to be as high as 67%, whilst fetal complications up to 80% of cases.1 The therapeutic gold standard and definitive treatment for PHP in pregnancy is minimally invasive parathyroidectomy in the second trimester. We report a case of a 22-year old primidgravida who underwent parathyroidectomy in the third trimester of her pregnancy for PHP with persistent hypercalcemia. She was also found to have Vitamin D deficiency which probably led to secondary hyperparathyroidism and made her hypercalcemia more apparent during pregnancy

    Acute mountain sickness is an illness caused by climbing to a high altitude without prior acclimatization. Neurological consequences, like parkinsonism following acute mountain sickness without lesion of brain MRI have been reported rarely. A healthy 56-year-old man presented with dysarthria and gait disturbance. Neurological examination revealed tremor of hands, limb rigidity, and bradykinesia. The symptoms developed approximately 30 days following a 3,500 m climb of the Annapurna in the Himalayas. Brain MRI did not reveal any abnormalities including globus pallidus. The parkinsonism symptoms persisted for about 3 months before a complete recovered was made. We suggest that parkinsonism can develop after climbing to a high altitude but that the symptoms can be transient if a brain MRI detects no abnormalities.

    Protein structure alignment and comparisons that are based on an alphabetical demonstration of protein structure are more simple to run with faster evaluation processes; thus, their accuracy is not as reliable as three-dimension (3D)-based tools. As a 1D method candidate, TS-AMIR used the alphabetic demonstration of secondary-structure elements (SSE) of proteins and compared the assigned letters to each SSE using the [Formula: see text]-gram method. Although the results were comparable to those obtained via geometrical methods, the SSE length and accuracy of adjacency between SSEs were not considered in the comparison process. Therefore, to obtain further information on accuracy of adjacency between SSE vectors, the new approach of assigning text to vectors was adopted according to the spherical coordinate system in the present study. Moreover, dynamic programming was applied in order to account for the length of SSE vectors. Five common datasets were selected for method evaluation. The first three datasets were small, but difficult to align, and the remaining two datasets were used to compare the capability of the proposed method with that of other methods on a large protein dataset. The results showed that the proposed method, as a text-based alignment approach, obtained results comparable to both 1D and 3D methods. It outperformed 1D methods in terms of accuracy and 3D methods in terms of runtime.

    Streptococcosis is an important disease of tilapia throughout the world. In Malaysia, streptococcosis outbreak was commonly reported during the 3-month period of high water temperature between April and July. This study describes the duration of protection following single and double booster dose regimes against streptococcosis in tilapia using a feed-based vaccine containing formalin-killed Streptococcus agalactiae. A total of 510 tilapias of 120 ± 10 g were selected and divided into 3 groups. Fish of Group 1 were vaccinated at weeks 0 and 2 (single booster group) while fish of Group 2 were vaccinated at weeks 0, 2 and 6 (double booster group) with a feed-based vaccine against streptococcosis. Fish of Group 3 was not vaccinated. Serum samples were collected weekly to determine the antibody level while samples of eye, brain and kidney were collected for bacterial isolation. At week 10, all fish were challenged with live S. agalactiae and the survival rate was determined.

    The complexity of physical, hormonal and psychocological changes in menopause may affect the sexual function in women. This study measured the prevalence of female sexual dysfunction (FSD) in Malaysian menopausal women. The associated factors were also examined in the study. A cross-sectional study involved 310 menopausal (defined as last menstrual period more than 12 months ago) who visited a menopausal clinic in a secondary referral hospital in the East Peninsular Malaysia. The prevalence and associated factors of female sexual dysfunction in the study subjects were determined. Sexual dysfunction was assessed using the Malay version of the female sexual function index (MVFSFI). Possible associated factors were collected in a pre-designed questionnaire. The prevalence of FSD for the menopausal women was 21.3%. Younger age was the only factor significantly associated with FSD in the study subjects (adjusted odds ratio=0.916, 95% CI=0.851-0.987). The prevalence of FSD was low in the Malaysian menopausal women and associated with younger age.
