1.Factors influencing physical inactivity among adults in Negeri Sembilan, Peninsular Malaysia
The Medical Journal of Malaysia 2019;74(5):389-393
Background: Physical inactivity remains the most important
modifiable risk factor in preventing a variety of noncommunicable diseases (NCDs) and has been identified to
be a risk factor for obesity, heart disease and cancers. This
study examined the prevalence and factors associated with
physical inactivity among the suburban adult population in
Port Dickson district, Negeri Sembilan, Peninsular Malaysia.
Material and Methods: This was a community based crosssectional study involving 397 adult respondents conducted
in February 2016. Data was collected by face-to-face
interview using a structured questionnaire. Data regarding
socio-demographic factors (age, gender, ethnicity,
education level, marital status and monthly income, working
hours), current behavioural stage of physical activity and
perceived benefits and barriers to physical activity were
collected. Physical activity measured using the International
Physical Activity Questionnaire (IPAQ) with the cut-off point
of less than 600 met-min per week was considered to be
physically inactive.
Results: The prevalence of physical inactivity among adult
population was 36.3%. Factors significantly associated with
physical inactivity included age, gender, marital status,
working hours and current behavioural stage of physical
activity.
Conclusion: Physical inactivity is high among the adult
community in Negeri Sembilan district, Peninsular Malaysia
and was strongly associated with age, gender, marital
status, working hours and current behavioural stage of
physical activity. It is important to identify individuals with
physical inactivity and its associated factors early as this
could severely affect the quality of life of the individuals

INTRODUCTIONThe interesting topic of cutaneous and subcutaneous metastasis from rectal carcinoma is discussed using 3 cases.
CLINICAL PICTUREThe first case was a 70-year-old man with T3N2M0 rectal mucinous adenocarcinoma, who developed an inflammatory subcutaneous metastasis at the left scapula 2 years after anterior resection. The second case was a 51-year-old man with T4N2M0 splenic flexure mucinous adenocarcinoma, who developed metastatic disease including a subcutaneous secondary to the back. The third case was a 53-year-old woman who developed vulval recurrence 10 months after abdomino-perineal resection for a low T3N1M0 rectal adenocarcinoma.
TREATMENTAll underwent wide resection.
CONCLUSIONThis entity is rare and usually signifies disseminated disease if found remote from the resection site and warrants a thorough metastatic work up. A high index of suspicion is recommended when encountered with unresolving skin lesions in cancer patients.

PURPOSE: Perianal adenocarcinoma arising from a chronic anorectal fistula is a rare condition for which the natural history and optimal management are not well established. For that reason, we conducted a retrospective analysis of 5 consecutive patients with a perianal adenocarcinoma arising from a chronic anorectal fistula managed at our institution from January 2014 to December 2015. METHODS: The patients were identified from a prospectively collected colorectal cancer database that included all patients managed for colorectal cancer at our institution. RESULTS: The median age at diagnosis was 64 years (range, 55–72 years). Magnetic resonance imaging (MRI) was the initial investigation for all patients and showed a hyperintense T2-weighted image. One patient underwent an abdominoperineal resection following neoadjuvant chemoradiotherapy and remained disease free during the 12-month follow-up. Three patients received neoadjuvant therapy with intent for surgery, but did not undergo surgery due to either worsening health or metastatic spread. One patient declined intervention. The median overall survival was 10.5 months (range, 2–19 months). CONCLUSION: A high index of suspicion is required to make a clinical diagnosis of an anal adenocarcinoma arising from a chronic fistula. Histologic diagnosis must be achieved to confirm the diagnosis. Multimodal therapy with neoadjuvant chemoradiotherapy followed by abdominoperineal resection is the treatment of choice.

Purpose:
Endoscopic total mastectomy (ETM) is predominantly performed with reconstruction using prostheses, lipofilling, omental flaps, latissimus dorsi flaps, or a combination of these techniques. Common approaches include minimal incisions, e.g., periareolar, inframammary, axillary, or mid-axillary line, which limit the technical ability to perform autologous flap insets and microvascular anastomoses, as such the ETM with free abdominal-based perforator flap reconstruction has not been robustly explored.
Methods:
We studied female patients with breast cancer who underwent ETM and abdominal-based flap reconstruction. Clinical-radiological-pathological characteristics, surgery, complications, recurrence rates, and aesthetic outcomes were reviewed.
Results:
Twelve patients underwent ETM with abdominal-based flap reconstruction. The mean age was 53.4 years (range 36–65). Of the patients, 33.3% were surgically treated for stage I, 58.4% for stage II, and 8.3% for stage III cancer. Mean tumor size was 35.4 mm (range 1–67). Mean specimen weight was 458.75 g (range 242–800). Of the patients, 92.3% successfully received endoscopic nipple-sparing mastectomy and 7.7% underwent intraoperative conversion to skin-sparing mastectomy after carcinoma was reported on frozen section of the nipple base. Mean operative time for ETM was 139 minutes (92–198), and the average ischemic time was 37.3 minutes (range 22–50). Fifty percent of patients underwent deep inferior epigastric perforator, 33.4% underwent MS-2 transverse rectus abdominis musculocutaneous (TRAM), 8.3% underwent MS-1 TRAM, and 8.3% underwent pedicled TRAM flap reconstruction. No cases required re-exploration, no flap failure occurred, margins were clear, and no skin or nippleareolar complex ischemiaecrosis developed. In the aesthetic outcome evaluation, 16.7% were excellent, 75% good, 8.3% fair, and none were unsatisfactory. No recurrences were observed.
Conclusion
ETM through a minimal-access inferior mammary or mid-axillary line approach, followed by immediate pedicled TRAM or free abdominal-based perforator flap reconstruction, can be a safe means of achieving an “aesthetically scarless” mastectomy and reconstruction through minimal incisions.

Dengue early warning system, based on many different factors including climatic factors, is likely to be a useful tool for predicting dengue cases. This study aims to assess the perceptions, attitudes, and responses to dengue early warning among a sample of residents in Kuala Lumpur, Malaysia as well as the factors associated with their willingness in participating dengue prevention public activity. A community-based cross-sectional study was conducted among residents of Titiwangsa District, Kuala Lumpur. A structured questionnaire was administered via face-to-face interview. About 75% of the respondents perceived dengue early warning as a useful tool for the community to take preventive measures. However, more than half did not know elevated temperature increases dengue cases. More than 80% wanted to know more how climate can be used to predict dengue outbreak. Willingness of participating in dengue control public activity was associated with age (p<0.001), educational level (p=0.005), perception (p<0.001), and attitude (p<0.001). Perception towards dengue early warning was positive among the urban residents. Majority of the participants reported good attitude with regard to dengue early warning while a minority demonstrated a poor response. Educational level, perception, and attitude are significantly associated with willingness to engage in dengue prevention public activity.

INTRODUCTION:
In Singapore, non-anaesthesiologists generally administer sedation during gastrointestinal endoscopy. The drugs used for sedation in hospital endoscopy centres now include propofol in addition to benzodiazepines and opiates. The requirements for peri-procedural monitoring and discharge protocols have also evolved. There is a need to develop an evidence-based clinical guideline on the safe and effective use of sedation by non-anaesthesiologists during gastrointestinal endoscopy in the hospital setting.
METHODS:
The Academy of Medicine, Singapore appointed an expert workgroup comprising 18 gastroenterologists, general surgeons and anaesthesiologists to develop guidelines on the use of sedation during gastrointestinal endoscopy. The workgroup formulated clinical questions related to different aspects of endoscopic sedation, conducted a relevant literature search, adopted Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology and developed recommendations by consensus using a modified Delphi process.
RESULTS:
The workgroup made 16 recommendations encompassing 7 areas: (1) purpose of sedation, benefits and disadvantages of sedation during gastrointestinal endoscopy; (2) pre-procedural assessment, preparation and consent taking for sedation; (3) Efficacy and safety of drugs used in sedation; (4) the role of anaesthesiologist administered sedation during gastrointestinal endoscopy; (5) performance of sedation; (6) post-sedation care and discharge after sedation; and (7) training in sedation for gastrointestinal endoscopy for non-anaesthesiologists.
CONCLUSION
These recommendations serve to guide clinical practice during sedation for gastrointestinal endoscopy by non-anaesthesiologists in the hospital setting.

INTRODUCTIONThe influenza pandemic has generated much interest in the press and the medical world. We report our experience with 15 cases of severe novel influenza A H1N1 (2009) infections requiring intensive care. The aim of this review is to improve our preparedness for epidemics and pandemics by studying the most severely affected patients.
CLINICAL PICTUREDuring the epidemic, hospitals were required to provide data on all confirmed H1N1 cases admitted to an intensive care unit (ICU) to the Ministry of Health. We abstracted information from this dataset for this report. To highlight learning points, we reviewed the case notes of, and report, the fi ve most instructive cases.
TREATMENTThere were 15 cases admitted to an ICU from July 4, 2009 to August 30, 2009. Two patients died.
CONCLUSIONSThe lessons we wish to share include the following: preparedness should include having intermediate-care facilities that also provide single room isolation and skilled nursing abilities, stringent visitor screening should be implemented and influenza may trigger an acute myocardial infarction in persons with risk factors.

Background:
and Purpose Tenecteplase is a thrombolytic agent with pharmacological advantages over alteplase and has been shown to be noninferior to alteplase for acute ischemic stroke in randomized trials. However, evidence pertaining to the safety and efficacy of tenecteplase in patients from different ethnic groups is lacking. The aim of this systematic review and metaanalysis was to investigate ethnicity-specific differences in the safety and efficacy of tenecteplase versus alteplase in patients with acute ischemic stroke.
Methods:
Following an International Prospective Register of Systematic Reviews (PROSPERO)- registered protocol (CRD42023475038), three authors conducted a systematic review of the PubMed/MEDLINE, Embase, Cochrane Library, and CINAHL databases for articles comparing the use of tenecteplase with any thrombolytic agent in patients with acute ischemic stroke up to November 20, 2023. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Two independent authors extracted data onto a standardized data collection sheet. A pairwise meta-analysis was conducted in risk ratios (RR).
Results:
From 34 studies (59,601 participants), the rate of complete recanalization was significantly higher (P<0.01) in Asian (RR: 1.91, 95% confidence interval [CI]: 1.30 to 2.80) versus Caucasian patients (RR: 0.99, 95% CI: 0.87 to 1.14). However, Asian patients (RR: 1.18, 95% CI: 0.87 to 1.62) had significantly higher (P=0.01) rates of mortality compared with Caucasian patients (RR: 1.10, 95% CI: 1.00 to 1.22). Caucasian patients were also more likely to attain a modified Rankin Scale (mRS) score of 0 to 2 at follow-up (RR: 1.14, 95% CI, 1.10 to 1.19) compared with Asian (RR: 1.00, 95% CI, 0.95 to 1.05) patients. There was no significant difference in the rate of symptomatic intracranial hemorrhage (P=0.20) and any intracranial hemorrhage (P=0.83) between Asian and Caucasian patients.
Conclusion
Tenecteplase was associated with significantly higher rates of complete recanalization in Asian patients compared with Caucasian patients. However, tenecteplase was associated with higher rates of mortality and lower rates of mRS 0 to 2 in Asian patients compared with Caucasian patients. It may be beneficial to study the variations in response to tenecteplase among patients of different ethnic groups in large prospective cohort studies.

Clitoria ternatea or Commonly known blue pea, is a perennial climber crop native to Asian countries. The current study was aimed to evaluate the antimicrobial activity C. ternatea extract on food borne microorganisms and its antifungal effect on Penicillium expansum. The extract showed significant antimicrobial activity against 3 Gram positive bacteria, 2 Gram negative bacteria and 1 filamentous fungus on disc diffusion assay. The extract also showed good biocidal effect on all Gram positive bacteria tested and P. expansum. However, the kill curve analysis revealed that the fungicidal activity of the extract against P. expansum conidia was depend on the concentration of the extract and the time of exposure of the conidia to the extract. The scanning electron micrograph of the extract treated P. expansum culture showed alterations in the morphology of fungal hyphae. The germination of P. expansum conidia was completely inhibited and conidial development was totally suppressed by the extract, suggesting the possible mode of action of anthocyanin. Besides, the extract also exhibited 5.0-log suppression of microbial growth relative to control in the rice model. The results indicate the potential use of the C. ternatea anthocyanin as food biopreservative.
