OBJECTIVE: Angioplasty and Stenting of intracranial atherosclerotic lesions have a higher complication rate and a large proportion of this is attributable to side branch arterial occlusion from forceful displacement of the atheroma into the ostia or snowplowing effect. This can result in severe disabilities when it result in small infarcts involving eloquent areas in the posterior circulation or the motor tracts. MATERIALS AND METHODS: We present a series of 6 cases utilizing a new dual catheter technique for maintaining the patency of at-risk vessels during angioplasty and stenting. There are several methods previously described to help reduce the incidence of stroke but because they do not have a physical presence in the ostia to protect it, they are unable to guarantee the patency of the vessel. RESULTS: All 6 patients underwent angioplasty and stenting with the technique. The patients were assessed for complications with post-procedure magnetic resonance imaging and no complications were found. CONCLUSION: In this preliminary series, the dual catheter technique appears to safe and effective in preventing occlusion of the adjacent branch arteries. This technique may facilitate the use of the Wingspan stent in the treatment of intracranial atherosclerotic stenotic segments by reducing the risk of peri-procedural stroke.

INTRODUCTIONThis study determines the associations between self-reported chronic conditions, limitations in activities of daily living and health-related quality of life (HRQoL) among community dwelling elderly in Singapore.
MATERIALS AND METHODSA population-based cross-sectional survey was conducted among a random sample of 4200 residents from 58 blocks of dwellings in Marine Parade housing estate between April and May 2011. A structured questionnaire was used to collect data on demographic characteristics; chronic disease profile, health screenings, healthcare utilisation, physical activity, activities of daily living (ADL) and functional ability and health related quality of life. Quality of life was assessed using European Quality of life 5 Domain (EQ-5D). Ordinary least squares (OLS) regression was used to identify independent predictors of health related quality of life.
RESULTSA total of 2454 respondents for included for analysis. Most of the respondents were females (57.2%) and aged between 65 and 74 years (48.5%). Among them, 79.1% of the respondents were Chinese. Approximately three-fourth (77.5%) of the survey respondents reported having at least one of the 13 chronic medical conditions; high blood pressure (57.7%), high blood cholesterol (51.6%), diabetes (22.9%) were the most commonly reported conditions. Independent predictors of HRQoL with greatest decrements in EQ-5D index and visual analog scores (VAS) were unemployment, self-reported depression, arthritis and osteoporosis and ADL limitations for activities such as "unable to shower", "unable to do housework" and elderly with depressive symptoms (GDS score≥5).
CONCLUSIONThe study had identified predictors of HRQoL in elderly Singapore residents and also provides community-based EQ-5D index and VAS scores associated with a wide variety of chronic conditions and ADL limitations.

INTRODUCTIONEmergency gastrectomy has been shown to be associated with poor morbidity and mortality rates. The aims of this study were to review the outcomes of emergency gastrectomy in our institution and to determine any factors that were associated with worse perioperative outcomes.
MATERIALS AND METHODSA retrospective review of all patients who underwent emergency gastrectomy for various indications from October 2003 to April 2009 was performed. All the complications were graded according to the classification proposed by Clavien and group.
RESULTSEighty-fi ve patients, median age 70 (range, 27 to 90 years), underwent emergency gastrectomy. The indications for the surgery included perforation, bleeding and obstruction in 45 (52.9%), 32 (37.6%) and 8 (9.4%) patients, respectively. The majority of the patients (n = 46, 54.1%) had an American Society of Anesthesiologists (ASA) score of 3. Partial or subtotal, and total gastrectomy were performed in 75 (88.2%) and 10 (11.8%) patients, respectively. Malignancy was the underlying pathology in 33 (38.8%) patients. The perioperative mortality rate was 21.2% (n = 18) with another 27 (31.8%) patients having severe complications. Twelve (14.1%) patients had a duodenal stump leak. The independent factors predicting worse perioperative complications included high ASA score and in perforation cases. Other factors such as malignancy, age and extent of surgery were not signifi cantly related. The presence of a duodenal stump leak was the only independent factor predicting mortality.
CONCLUSIONEmergency gastrectomy is associated with dismal morbidity and mortality rates. Patients with high ASA scores and perforations fared worse, and duodenal stump leak increases the risk of mortality.

INTRODUCTIONDepression in the elderly is a major public health issue. Socioeconomic status (SES) and social support are strong risk factors for depression. This study aimed to investigate the influence of SES and social support in elderly depression, and the modifying effect of social support on the relationship between SES and depression.
MATERIALS AND METHODSA community-based survey was conducted on residents≥60 years old. Depressive symptoms were determined with scores≥5 using the 15-item Geriatric Depression Scale (GDS). Multivariable logistic regression was performed to determine the odds ratio (OR) of depressive symptoms with respect to SES and social support, and interaction terms between the two variables.
RESULTSOf 2447 responses analysed, 188 (7.8%) respondents had depressive symptoms. Living in 2-room housing, living alone/with a domestic helper, infrequent leisure time with children/grandchildren or being childless, and feeling socially isolated were independently associated with depressive symptoms. Relative to residents living with spouse and children in 4-/5-room housing, the highest ORs for depressive symptoms were those living with spouse and children in 2-room (OR: 3.06, P<0.05), followed by living with children only in 3-room (OR: 2.98, P<0.05), and living alone/with a domestic helper in 4-/5-room (OR: 2.73, P<0.05). Living with spouse only appears to buffer against depressive symptoms across socioeconomic classes, although the effect was not statistically significant.
CONCLUSIONLow social support and low SES significantly increased the odds of depressive symptoms. The moderating effect of social support on depression was however not consistent across SES groups. Specific interventions need to target different SES groups to better help older adults at risk of developing depression.

INTRODUCTIONIn Hong Kong, obesity and its associated co-morbidities are increasingly becoming a health and societal burden. Conservative weight management therapy is ineffective in maintaining substantial weight loss in severely obese patients and more invasive interventions are required to achieve sustainable weight loss.
MATERIALS AND METHODSInvasive bariatric procedures were introduced to Hong Kong in 2002. Severely obese patients will be seen in a combined obesity clinic where multi-disciplinary assessment was carried out before interventional therapy. Patients will be allocated to various bariatric surgeries such as laparoscopic adjustable gastric banding (LAGB), laparoscopic sleeve gastrectomy (LSG) or laparoscopic gastric bypass (LGB) when operative criteria were met. For selected patients who were not suitable or refused surgical treatment, endoscopic placement of intragastric balloon (IGB) will be used as an alternative weight control option. Multi-disciplinary approach was also applied during perioperative period to accomplish different clinical needs for the individual patient.
RESULTSOver 500 patients were seen in our unit seeking advice on severe obesity. Two hundred and twenty-five patients received interventional therapy which included LAGB (n = 57), LSG (n = 71), LGB (n = 7) and IGB programme (n = 120). Thirty patients (25%) received second bariatric surgery after IGB removal. Adverse events occurred in 20 patients (7.8%) and there was no operative mortality. At 2 years, the mean percentage of excessive weight loss (%EWL) for LAGB, LSG and LGB are 34%, 51% and 61%, respectively. In those patients who received IGB alone, the mean %EWL at removal and 6 months after removal were 44% and 34%, respectively.
CONCLUSIONSThrough a multi-disciplinary weight management programme with different specialties and various bariatric procedures, favourable results can be achieved in patients with severe obesity.

INTRODUCTIONThe aim of the study was to describe the prevalence and risk factors for diabetic retinopathy in a multi-ethnic diabetic patient cohort referred for retinal evaluation from a nationwide diabetic retinopathy screening programme in Singapore.
MATERIALS AND METHODSSeven hundred and forty-two patients, aged 21 to 95, referred for suspected diabetic retinopathy on annual one-field non-mydriatic 45 degree retinal photographs (Topcon TRC-NW6, Topcon Corporation, Tokyo, Japan) from primary care to the Singapore National Eye Centre diabetic retinopathy clinic were included. The photographs had been interpreted by 24 trained family physicians accredited every 2 years with a training programme. Patients underwent a standardised interview and examination. Fundi were examined with indirect ophthalmoscopy by 2 examiners. Presence and severity of diabetic retinopathy was graded into none, mild, moderate, severe, very severe non-proliferative diabetic retinopathy and proliferative diabetic retinopathy. Macular oedema and clinically significant macular oedema were also graded.
RESULTSNinety-nine per cent of patients were type 2 diabetics. The prevalence of diabetic retinopathy was 38.1%, visionthreatening retinopathy was 11.8% and macular oedema was 6.9%. There were no racial differences. Significant predictors of any retinopathy were longer duration of diabetes, lower body mass index, being on treatment for hypertension, hypercholesterolaemia and use of diabetic medication. Predictors for vision-threatening retinopathy were younger age, longer duration of diabetes and lower body mass index.
CONCLUSIONSThe use of one-field non-mydriatic 45 degree photography as a screening tool for diabetic retinopathy resulted in a cohort of which 38.1% had diabetic retinopathy. Risk factors for diabetic retinopathy of this cohort are also presented.

INTRODUCTIONThis study aims to determine the association of geriatric syndromes and depressed mood among respondents with diabetes in a lower income community; and their association with self-management, lifestyle behaviour, and healthcare utilisation. This paper focuses primarily on the 114 respondents with diabetes aged 50+ to inform policy formulation at the community level.
MATERIALS AND METHODSA pilot community health assessment was conducted in 4 blocks of 1- and 2-room apartments in Toa Payoh district from July to November 2009. Using a standard questionnaire, interviewers conducted face-to-face interviews with household members on chronic diseases, geriatric syndromes and health-related behaviour. Data were analysed using SPSSv15.
RESULTSA total of 795 respondents were assessed with a response rate of 61.8%. Of 515 (64.8%) aged 50+ analysed in this study, 22.1% reported having diabetes, of whom 31.6% reported being depressed. Respondents with diabetes who reported being depressed had a higher prevalence of geriatric syndromes compared with those non-depressed; i.e. functional decline (30.6% vs 5.1%, P <0.001); falls (33.3% vs 10.3%, P = 0.003); stumbling (30.6% vs 10.3%, P = 0.007); urinary incontinence (33.3% vs 5.1%, P <0.001), progressive forgetfulness (27.8% vs 6.4%, P = 0.002) and poor eyesight (22.2% vs 6.4%, P = 0.014). They were less likely to comply with medications (86.1% vs 97.3%, P = 0.026) and performed exercise (13.9% vs 53.8%, P <0.001). More had hospital admissions (13.9% vs 7.7%); and they had more outpatient visits per person (2.4 visits vs 0.9 visits, P = 0.03) at Specialist Outpatient Clinics.
CONCLUSIONGeriatric syndromes were associated with the presence of depressed mood among persons with diabetes in the lower income group. As those with depressed mood had more unfavourable self-management and lifestyle behaviour, and utilise higher healthcare services, diabetes management must take these findings into consideration.

9.Effects of dietary supplementation of Sonneratia alba extract on immune protection and disease resistance in goldfish against Aphanomyces invadans
Tropical Biomedicine 2019;36(1):274-288
A 30-day study was conducted on the effects of diets supplementation with 0,
1.0%, 3.0%, and 5.0% Sonneratia alba leaf extracts on healthy goldfish, Carassius auratus
against Aphanomyces invadans. Results showed that the numbers of white blood cell
significantly increased in the infected fish fed with 3.0% and 5.0% supplementation diets after
the second week of experiments. Whilst the numbers of red blood cell significantly decreased
in the infected fish fed with 0 and 1.0% supplementation diets. After the third week of feeding
trials, the total protein, albumin level and lysozyme activity were significantly increased in
the infected fish fed with 3.0% and 5.0% supplementation diets. However, the myeloperoxidase
activity significantly increased after two weeks in the infected fish were fed with 3.0% and
5.0% supplementation diets. The cumulative mortality rate of goldfish decreased up to 17%
when the infected fish were fed with 3.0% supplementation diets. This study indicates that
enriched fish feed with 3.0% and 5.0% S. alba leaf extracts enhanced the non-specific immunity
and survival rate of the goldfish, suggesting that the extract may serve as a potential
prophylactic treatment against A. invadans.

INTRODUCTION: Psychiatric comorbidity is common in patients with functional dyspepsia (FD) but a good screening tool for psychiatric disorders in gastrointestinal clinical practice is lacking. Aims: 1) Evaluate the performance and optimal cut-off of 12-item General Health Questionnaire (GHQ-12) as a screening tool for psychiatric disorders in FD patients; 2) Compare health-related quality of life (HRQoL) in FD patients with and without psychiatric comorbidities. METHODS: Consecutive patients fulfilling Rome III criteria for FD without medical co-morbidities and gastroesophageal reflux disease were recruited in a gastroenterology clinic. The followings were conducted at 4 weeks after index oesophagogastroduodenoscopy: self-administrated questionnaires on socio-demographics, dyspeptic symptom severity (4-point Likert scale), GHQ-12, and 36-item short-form health survey (SF-36). Psychiatric disorders were diagnosed with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) by a trained psychiatrist, which served as reference standard. RESULTS: 55 patients underwent psychiatrist-conducted interview and questionnaire assessment. 27 (49.1%) had current psychiatric disorders as determined by SCID (anxiety disorders: 38.2%, depressive disorders: 16.4%). Receiver operating characteristic curve analysis of GHQ-12 revealed an area under curve of 0.825 (95%CI: 0.698-0.914). Cut-off of GHQ-12 at > or =3 gave a sensitivity of 63.0% (95%CI = 42.4-80.6%) and specificity of 92.9% (95%CI = 76.5%-98.9%). Subjects with co-existing psychiatric disorders scored significantly lower in multiple domains of SF-36 (mental component summary, general health, vitality and mental health). By multivariate linear regression analysis, current psychiatric morbidities (Beta = -0.396, p = 0.002) and family history of psychiatric illness (Beta = -0.299, p = 0.015) were independent risk factors for poorer mental component summary in SF-36, while dyspepsia severity was the only independent risk factor for poorer physical component summary (Beta = -0.332, p = 0.027). CONCLUSIONS: Concomitant psychiatric disorders adversely affect HRQoL in FD patients. The use of GHQ-12 as a reliable screening tool for psychiatric disorders allows early intervention and may improve clinical outcomes of these patients.
