Background: Singapore’s healthcare system allows both antibiotic prescribing and dispensing across public and private primary care settings, presenting an ideal context to learn from systems where dispensing is closely tied to diverse operational models and funding mechanisms. Aim: To explore processes underpinning decision-making for antibiotic prescribing by primary care doctors in Singapore, by examining doctors’ experiences in different primary care settings. Methods: Thirty semi-structured interviews were conducted with 17 doctors working in publicly funded primary care clinics (polyclinics) and 13 doctors working in private general practitioner (GP) clinics (solo, small group and large group practices). Interviews were audio-recorded and transcribed verbatim. Data were analysed using applied thematic analysis. Results: Given the lack of National Guidelines for antibiotic prescribing in the Singapore context, this practice is currently non-standardised in both private and publicly funded primary care settings. Themes contributing to best practice narratives relate to having independent funding sources and control over drug formulary orders, and valuing reduction in antimicrobial resistance (AMR). The existence of trusting patient-doctor relationships, and reasonable patient loads were observed to allow joint participatory and informed decision-making that further enabled appropriate prescribing. The importance of monitoring and application of data/evaluations to inform practice was a minority theme, nevertheless underpinning all levels of optimal care delivery.Conclusions: A model for appropriate antibiotic prescribing-related interventions needs to prioritise addressing and shaping organisational and personal Valuing of AMR reduction. These values have to also Align with wider systemic constraints experienced in publicly funded institutions, operational management of private clinics and interactions with patients at the interpersonal level. The overcoming of such constraints and allowing time for patient Liaison and trust building will crystalise these earlier initiatives. Use of data to monitor and Evaluate antibiotic prescribing, informing optimal delivery systems should be routinely shared for transparency and to improve prescribing practices. These dimensions are summarised in the VALUE model for appropriate antibiotic prescribing and stewardship in primary care, which is recommended as transferable to diverse contexts.

- Abstract
BACKGROUND: Personalised care and support planning (CSP) has been shown to improve diabetes outcomes, patient experience and provider morale in the care of persons living with diabetes. However, this has not been confirmed in controlled studies. Patient Activation through Community Empowerment/Engagement for Diabetes Management (PACE-D) is a pragmatic controlled trial that evaluates the effectiveness of personalised CSP in persons living with diabetes in the public primary care setting in Singapore. METHODS: Teamlet-empanelled patients with diabetes at four polyclinics are recruited for this study. Participants who attend either of the two Intervention clinics are sent their investigation results in a care planning letter (CPL) to prepare them for the CSP conversation. This conversation is facilitated by a trained CSP practitioner who engages them in discussion of concerns, goals and action plans, and documents their plans for subsequent review. Participants in the two Control clinics will receive standard diabetes care. Participants will complete two or more CSP conversations (Intervention) or regular consultations (Control) at the annual review visits within the 18 months of the study. The sample size is calculated at 1620 participants, with glycated haemoglobin (HbA1c) as the primary outcome measure. Secondary outcome measures include patient activation (as measured by PAM-13) and changes in healthcare utilisation and cost. DISCUSSION: This study is a pragmatic trial that evaluates the effectiveness of personalised CSP in persons living with diabetes in a real world setting. It promises to provide insights with regard to the implementation of this model of care in Singapore and the region. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT04288362. Retrospectively registered on 28 February 2020.

Abiraterone acetate, a drug that blocks endogenous androgen synthesis, plus prednisone is indicated for metastatic castration-resistant prostate cancer. We evaluated the clinical benefit of abiraterone acetate plus prednisone with androgen-deprivation therapy in patients with newly diagnosed, metastatic, castration-sensitive prostate cancer. In this double-blind, placebo-controlled, phase 3 trial, we randomly assigned 1199 patients to receive either androgen-deprivation therapy plus abiraterone acetate (1000 mg daily, given once daily as four 250-mg tablets) plus prednisone (5 mg daily) (the abiraterone group) or androgen-deprivation therapy plus dual placebos (the placebo group). The two primary end points were overall survival and radiographic progression-free survival. After a median follow-up of 30.4 months at a planned interim analysis (after 406 patients had died), the median overall survival was significantly longer in the abiraterone group than in the placebo group (not reached vs. 34.7 months) (hazard ratio for death, 0.62; 95% confidence interval [CI], 0.51 to 0.76; P

- Abstract
Data on primary care antibiotic prescription practices for children in Singapore, which are essential for health care policy, are lacking. We aimed to address this gap and to benchmark prescription practices against international standards. A retrospective cohort database study on antibiotic prescriptions for children (aged < 18 years) who visited six public primary care clinics in Singapore between 2018 and 2021 was conducted. Data were categorised according to the World Health Organization's Access, Watch, Reserve (WHO AWaRe) classification. Quality indicators from the European Surveillance of Antimicrobial Consumption Network (ESAC-Net) and the National Institute for Health and Care Excellence (NICE) guidelines were used as a measure of appropriateness of antibiotic prescribing at the individual and overall patient level. In 831,669 polyclinic visits by children between 2018 and 2021, there was a significant reduction in mean antibiotics prescribed per month during pandemic years (2020-2021) compared to pre-pandemic (2018-2019) (MD 458.3, 95% CI 365.9-550.7). Most prescriptions (95.8%) for acute conditions fell within the WHO AWaRe "Access" group. Antibiotic prescription significantly exceeded (55.2%) the relevant quality indicator for otitis media (0-20%). The proportion of children receiving appropriate antibiotics for acute respiratory infections ( n = 4506, 51.3%) and otitis media ( n = 174, 49.4%) was low compared to the quality indicator (80-100%). There is a need to develop local evidence-based primary care antibiotic guidelines, as well as to support the development of stewardship programmes.

- Abstract
Objective: Dental caries is preventable, yet it remains a common childhood disease. As children are dependent on their parents for oral health care, oral health education for parents is essential to ensure they understand the risk factors and consequences of dental caries and their role in its prevention. This study aims to explore parents' oral health education needs to enable the development and provision of a tailored online oral health education module., Methods: Online focus group discussions were conducted among Malaysian parents to gather information about the content, layout and presentation of oral health information parents sought for the provision of oral health care for their children. Video recordings were transcribed verbatim and thematic analysis was performed using an inductive approach., Results: In total, 24 parents participated in the discussions and 4 main themes were uncovered. The first theme was perceived information needs related to dental caries, oral health care and the importance of deciduous teeth. The second theme was parents' preferred information resources which were social media, dentists, mobile phone applications and medical personnel. Thirdly, information delivery format and specific characteristics were recommended. The final theme was challenges and barriers faced in maintaining oral health due to parental constraints, child behaviour and external factors., Conclusion: Parents' profound feedback and experiential standpoint stipulate the need for the development and delivery of a comprehensible and visually engaging oral health education module by healthcare professionals via social media to enable access to evidence-based information consistently., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

- Abstract
Background: Antibiotic prescription practices in primary care in Singapore have received little scholarly attention. In this study, we ascertained prescription prevalence and identified care gaps and predisposing factors., Methods: A retrospective study was conducted on adults (>21 years old) at six public primary care clinics in Singapore. Prescriptions >14 days were excluded. Descriptive statistics were used to showcase the prevalence data. We used chi-square and logistic regression analyses to identify the factors affecting care gaps., Results: A total of 141,944 (4.33%) oral and 108,357 (3.31%) topical antibiotics were prescribed for 3,278,562 visits from 2018 to 2021. There was a significant reduction in prescriptions ( p < 0.01) before and after the pandemic, which was attributed to the 84% reduction in prescriptions for respiratory conditions. In 2020 to 2021, oral antibiotics were most prescribed for skin (37.7%), genitourinary (20.2%), and respiratory conditions (10.8%). Antibiotic use in the "Access" group (WHO AWaRe classification) improved from 85.6% (2018) to 92.1% (2021). Areas of improvement included a lack of documentation of reasons for antibiotic use, as well as inappropriate antibiotic prescription for skin conditions., Conclusion: There was a marked reduction in antibiotic prescriptions associated with the onset of the COVID-19 pandemic. Further studies could address the gaps identified here and evaluate private-sector primary care to inform antibiotic guidelines and the local development of stewardship programs.

- Abstract
Background: Recent evidence suggested the link between nephrolithiasis and renal function impairment. We aimed to determine the renal function profile and potential factors associated with reduced renal function amongst renal stone formers in multi-ethnic Asians., Methods: We conducted a cross-sectional study involving patients undergoing percutaneous nephrolithotomy between May 2015 and December 2019. Reduced renal function was defined as having estimated glomerular filtration rate < 60 ml/min per 1.73 m2. Renal stone samples were collected and quantified using infrared spectroscopy. Potential factors associated with reduced renal function including age, ethnicity, educational level, history of diabetes, hypertension, gout, hydronephrosis, serum uric acid level, and type of renal stone were evaluated using univariable and multivariable analyses., Results: A total of 1162 patients from a multi-ethnic population (Malays 67%, Chinese 19%, Indians 13% and indigenous people 1%) with median age of 57 years (Interquartile range 48-64) were enrolled in the study. Almost a third of patients were found with reduced renal function. Multivariable analysis showed that the odds of having reduced renal function increased with age, ethnicity, lower educational level, history of diabetes, hypertension, gout, bilateral hydronephrosis, elevated serum uric acid level and infection stone., Conclusions: Reduced renal function varies between ethnicities and all age groups of renal stone formers. In addition to age and ethnicity, cardiovascular risk factors including diabetes and hypertension may also need to be taken into account in managing stone patients with reduced renal function., Competing Interests: The authors have read the journal’s policy and have the following competing interests to declare: Avro Abadi Sdn Bhd provided support for this study by funding the Thermo Scientific Nicolet iS5 Fourier-transform infrared (FT-IR) spectrometer. This does not alter our adherence to PLOS ONE policies on sharing data and materials. There are no patents, products in development or marketed products associated with this research to declare.

- Abstract
Prostate cancer is the third most common cancer in Malaysia with the lifetime risk of 1 in 117 men. Here, we initiated a longitudinal Malaysia Prostate Cancer (M-CaP) Study to investigate the clinical and tumour characteristics, treatment patterns as well as disease outcomes of multi-ethnic Asian men at real-world setting. The M-CaP database consisted of 1839 new patients with prostate cancer diagnosed between 2016 and 2018 from nine public urology referral centres across Malaysia. Basic demographic and clinical parameters, tumour characteristics, primary treatment, follow-up and vital status data were retrieved prospectively from the hospital-based patients' case notes or electronic medical records. Primary endpoints were overall survival (OS) and biochemical progression-free survival (bPFS). The median age at diagnosis of M-CaP patients was 70 years (interquartile range, IQR 65-75). Majority of patients were Chinese (831, 45.2%), followed by Malays (704, 38.3%), Indians (124, 6.7%) and other races (181, 9.8%). The median follow-up for all patients was 23.5 months (IQR 15.9-33.6). Although 58.1% presented with late-stage cancer, we observed ethnic and geographic disparities in late-stage prostate cancer diagnosis. Curative radiotherapy and primary androgen deprivation therapy were the most common treatment for stage III and stage IV diseases, respectively. The median OS and bPFS of stage IV patients were 40.1 months and 19.2 months (95% CI 17.6-20.8), respectively. Late stage at presentation remains a challenge in multi-ethnic Asian men. Early detection is imperative to improve treatment outcome and survival of patients with prostate cancer., (© 2021 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

- Abstract
Background: Singapore's healthcare system presents an ideal context to learn from diverse public and private operational models and funding systems., Aim: To explore processes underpinning decision-making for antibiotic prescribing, by considering doctors' experiences in different primary care settings., Methods: Thirty semi-structured interviews were conducted with 17 doctors working in publicly funded primary care clinics (polyclinics) and 13 general practitioners (GP) working in private practices (solo, small and large). Data were analysed using applied thematic analysis following realist principles, synthesised into a theoretical model, informing solutions to appropriate antibiotic prescribing., Results: Given Singapore's lack of national guidelines for antibiotic prescribing in primary care, practices are currently non-standardised. Themes contributing to optimal prescribing related first and foremost to personal valuing of reduction in antimicrobial resistance (AMR) which was enabled further by organisational culture creating and sustaining such values, and if patients were convinced of these too. Building trusting patient-doctor relationships, supported by reasonable patient loads among other factors were consistently observed to allow shared decision-making enabling optimal prescribing. Transparency and applying data to inform practice was a minority theme, nevertheless underpinning all levels of optimal care delivery. These themes are synthesised into the VALUE model proposed for guiding interventions to improve antibiotic prescribing practices. These should aim to reinforce intrapersonal Values consistent with prioritising AMR reduction, and Aligning organisational culture to these by leveraging standardised guidelines and interpersonal intervention tools. Such interventions should account for the wider systemic constraints experienced in publicly funded high patient turnover institutions, or private clinics with transactional models of care. Thus, ultimately a focus on Liaison between patient and doctor is crucial. For instance, building in adequate consultation time and props as discussion aids, or quick turnover communication tools in time-constrained settings. Message consistency will ultimately improve trust, helping to enable shared decision-making. Lastly, Use of monitoring data to track and Evaluate antibiotic prescribing using meaningful indicators, that account for the role of shared decision-making can also be leveraged for change., Conclusions: These VALUE dimensions are recommended as potentially transferable to diverse contexts, and the model as implementation tool to be tested empirically and updated accordingly., (© 2021.

- Abstract
The J-CAPRA score is an assessment tool which stratifies risk and predicts outcome of primary androgen deprivation therapy (ADT) using prostate-specific antigen, Gleason score, and clinical TNM staging. Here, we aimed to assess the generalisability of this tool in multi-ethnic Asians. Performance of J-CAPRA was evaluated in 782 Malaysian and 16,946 Japanese patients undergoing ADT from the Malaysian Study Group of Prostate Cancer (M-CaP) and Japan Study Group of Prostate Cancer (J-CaP) databases, respectively. Using the original J-CAPRA, 69.6% metastatic (M1) cases without T and/or N staging were stratified as intermediate-risk disease in the M-CaP database. To address this, we first omitted clinical T and N stage variables, and calculated the score on a 0-8 scale in the modified J-CAPRA scoring system for M1 patients. Notably, treatment decisions of M1 cases were not directly affected by both T and N staging. The J-CAPRA score threshold was adjusted for intermediate (modified J-CAPRA score 3-5) and high-risk (modified J-CAPRA score ≥6) groups in M1 patients. Using J-CaP database, validation analysis showed that overall survival, prostate cancer-specific survival, and progression-free survival of modified intermediate and high-risk groups were comparable to those of original J-CAPRA (p > 0.05) with Cohen's coefficient of 0.65. Around 88% M1 cases from M-CaP database were reclassified into high-risk category. Modified J-CAPRA scoring system is instrumental in risk assessment and treatment outcome prediction for M1 patients without T and/or N staging., (© 2020 The Authors.

- Abstract
With the aging population and consequent increase in associated prevalence of frailty, dementia, and multimorbidity, primary care physicians will be overwhelmed with the complexity of the psychosocial and clinical presentation. Geriatric syndromes including frailty, sarcopenia, cognitive impairment, and anorexia of aging (AA) either in isolation or in combination are associated with an increased risk of adverse outcomes and if recognized early, and appropriately managed, will lead to decreased disability. Primary care practices are often located in residential settings and are in an ideal position to incorporate preventive screening and geriatric assessment with personalized management. However, primary care physicians lack the time, multidisciplinary resources, or skills to conduct geriatric assessment, and the limited number of geriatricians worldwide further complicates the matter. There is no one effective strategy to implement geriatric assessment in primary care which is rapid, cost-effective, and do not require geriatricians. Rapid Geriatric Assessment (RGA) takes <5 min to complete. It screens for frailty, sarcopenia, AA, and cognition with assisted management pathway without the need of a geriatrician. We developed RGA iPad application for screening with assisted management in two primary care practices and explored the feasibility and overall prevalence of frailty, sarcopenia, and AA. The assessment was conducted by trained nurses and coordinators. Among 2,589 older patients ≥65 years old, the prevalence of frailty was 5.9%, pre-frail 31.2%, and robust 62.9%. Fatigue was present in 17.8%, and among them, the prevalence of undiagnosed depression as assessed by the Patient Health Questionnaire (PHQ)-9 was 76.4% and 13.5% of total. The prevalence of sarcopenia was 15.4%, and 13.9% experienced at least one fall in the past year. AA was prevalent in 10.9%. The time taken to do the assessment with defined algorithm was on average 5 min or less per patient, and 96% managed to complete the assessment prior to seeing their doctor in the same session. The RGA app is a rapid and feasible tool to be used by any healthcare professional in primary care for identification of geriatric syndrome with assisted management., (Copyright © 2020 Merchant, Hui, Kwek, Sundram, Tay, Jayasundram, Chen, Ng, Tan and Morley.)

- Abstract
Background: Personalised care and support planning (CSP) has been shown to improve diabetes outcomes, patient experience and provider morale in the care of persons living with diabetes. However, this has not been confirmed in controlled studies. Patient Activation through Community Empowerment/Engagement for Diabetes Management (PACE-D) is a pragmatic controlled trial that evaluates the effectiveness of personalised CSP in persons living with diabetes in the public primary care setting in Singapore., Methods: Teamlet-empanelled patients with diabetes at four polyclinics are recruited for this study. Participants who attend either of the two Intervention clinics are sent their investigation results in a care planning letter (CPL) to prepare them for the CSP conversation. This conversation is facilitated by a trained CSP practitioner who engages them in discussion of concerns, goals and action plans, and documents their plans for subsequent review. Participants in the two Control clinics will receive standard diabetes care. Participants will complete two or more CSP conversations (Intervention) or regular consultations (Control) at the annual review visits within the 18 months of the study. The sample size is calculated at 1620 participants, with glycated haemoglobin (HbA1c) as the primary outcome measure. Secondary outcome measures include patient activation (as measured by PAM-13) and changes in healthcare utilisation and cost., Discussion: This study is a pragmatic trial that evaluates the effectiveness of personalised CSP in persons living with diabetes in a real world setting. It promises to provide insights with regard to the implementation of this model of care in Singapore and the region., Trial Registration: ClinicalTrials.gov Identifier NCT04288362.

- Abstract
Background: Approximately one-third of all adults worldwide are diagnosed with multiple chronic conditions (MCCs). The literature has identified several challenges facing providers and patients coping with managing MCCs in the community, yet few studies have considered their viewpoints in combination. A qualitative study involving healthcare providers and users was thus conducted to examine facilitators and barriers of managing patients with MCCs in the community in Singapore., Methods: This study involves 26 semi-structured interviews with 10 physicians, 2 caregivers and 14 patients seeking treatment in the polyclinics that provide subsidised primary care services. Topic guides were developed with reference to the literature review, Chronic Care Model (CCM) and framework for patient-centred access to healthcare., Results: Despite the perceived affordability and availability of the support system, some patients still encountered financial difficulties in managing care. These include inadequacy of the nation-wide medical savings scheme to cover outpatient treatment and medications. Half of healthcare users did not know where to seek help. While patients could access comprehensive services in polyclinics, those who did not visit the clinics might not receive timely care. Furthermore, patients reported long consultation waiting time. Physicians were able to propose and drive quality improvement projects to improve care quality. However, there were challenges to delivering safe and quality care with limited consultation duration due to the need to manage high patient load and waiting time, inadequate communication with specialists to coordinate care, and resource constraints in managing complex patients. Although providers could equip patients with self-management and lifestyle-related guidelines, patients' actions are influenced by multiple factors, including work requirements, beliefs and environment., Conclusions: There were barriers on care access, delivery and self-management. It is crucial to adopt a whole-of-society approach involving individuals, community, institutions and policymakers to improve and support MCC management. This study has also highlighted the importance of considering the different viewpoints of healthcare providers and users in policy formulation and community care planning.

- Abstract
Objective: To examine the results of the Malaysian Advanced Prostate Cancer Consensus Conference (MyAPCCC) 2018, held for assessing the generalizability of consensus reached at the Advanced Prostate Cancer Consensus Conference (APCCC 2017) to Malaysia, a middle-income country., Methods: Six key sections were chosen: (1) high-risk localized and locally advanced prostate cancer, (2) oligometastatic prostate cancer, (3) castration-naïve prostate cancer, (4) castrate resistant prostate cancer, (5) use of osteoclast-targeted therapy and (6) global access to prostate cancer drugs. There were 101 consensus questions, consisting of 91 questions from APCCC 2017 and 10 new questions from MyAPCCC 2018, selected and modified by the steering committee; of which, 23 questions were assessed in both ideal world and real-world settings. A panel of 22 experts, comprising of 11 urologists and 11 oncologists, voted on 101 predefined questions anonymously. Final voting results were compared with the APCCC 2017 outcomes., Results: Most voting results from the MyAPCCC 2018 were consistent with the APCCC 2017 outcomes. No consensus was achieved for controversial topics with little level I evidence, such as management of oligometastatic disease. No consensus was reached on using high-cost drugs in castration-naïve or castration-resistant metastatic prostate cancer in real-world settings. All panellists recommended using generic drugs when available., Conclusions: The MyAPCCC 2018 voting results reflect the management of advanced prostate cancer in a middle-income country in a real-world setting. These results may serve as a guide for local clinical practices and highlight the financial challenges in modern healthcare., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)

- Abstract
Introduction: Prostate cancer is a heterogenous disease and the mechanisms that drive it to behave differently are not well understood. Tumour expression of the ERG oncogene occurs in the majority of patients with prostate cancer in Western studies. This is considered to be oncogenic as ERG acts as a transcription factor to regulate genes involved in tumour proliferation and invasion. In this study we investigated expression of ERG in Malaysian men with prostate cancer., Methods: Tissues were collected from 80 patients with clinically detected prostate cancer and treated with radical prostatectomy. Cases were tested for ERG by immunohistochemistry using the mouse monoclonal antibody EP111. All blocks on 48 cases were tested in order to determine the extent of heterogeneity of ERG expression within individual cases. ERG expression was analysed in relation to patient age, ethnicity and tumour stage and grade., Results: Forty-six percent of cases were ERG positive. There was no significant association between ERG and tumour grade or stage. Sixty-nine percent of Indian patients had ERG positive tumours; this was significantly higher (p=0.031) than for Chinese (40%) and Malay (44%) patients. Heterogeneity of ERG expression, in which both positive and negative clones were present, was seen in 35% of evaluated cases. Evaluation by tumour foci showed younger patients had more ERG positive tumour foci than older patients (p=0.01). Indian patients were more likely to have the majority of tumour foci with ERG staining positively, compared to either Chinese or Malay patients (P <0.01)., Conclusion: In this study, tumour expression of ERG was more likely to occur in patients of Indian ethnicity.

- Abstract
Objectives: To develop a simple prostate volume (PV) calculator that can aid in managing patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement at daily urology services in developing Asian countries., Materials and Methods: We conducted a cross-sectional study of men aged above 40 years with no history of prostate cancer, prostate surgery, or 5α-reductase inhibitor treatment. Serum prostate-specific antigen (PSA) and total PV were measured in each subject. Potential sociodemographic and clinical variables including age, weight, comorbidities, and International Prostate Symptom Score (IPSS) were collected. Of 1034 subjects, 837 were used in building the PV calculator using regression analysis. The remaining 1/5 (n = 197) was used for model validation., Results: There were 1034 multiethnic Asian men (Chinese 52.9%, Malay 35.4%, and Indian 11.7%) with mean age of 60 ± 7.6 years. Average PV was 29.4 ± 13.0 mL while the overall mean of PSA was 1.7 ± 1.7 ng/mL. We identified age, IPSS, weight, and PSA (all P <.05) in the PV regression model. Using the validation set, the coefficient of determination (R
2 ) of this PV calculator was 0.47 where PV = 20.6 + (age - 60) × 0.1 + (IPSS score) × 0.1 + (Weight - 70) × 0.3 + (history of alpha-blocker treatment for LUTS) × 9.6 + PSA × 3.7. The area under curve of this model in predicting PV above 30 mL and 40 mL were 0.82 (95% confidence interval, 0.75-0.88) and 0.91 (95% confidence interval, 0.87-0.96), respectively., Conclusion: We develop a PV calculator that is simple and accurate to be used in routine clinical consultation for patients with LUTS. A separate study is important to confirm and to validate the findings in other populations., (Copyright © 2018 Elsevier Inc. All rights reserved.)- Published

- Abstract
Objectives: To determine the lower urinary tract symptoms (LUTS) profile and factors affecting its degree of severity including cardiovascular risk profile, age, ethnicity, education level and prostate volume in a multiethnic Asian setting., Materials and Methods: We conducted a cross-sectional study of 1021 men aged 40-79 years with no clinical evidence of prostate cancer, prostate surgery or 5α-reductase inhibitor treatment of known prostate conditions. The severity of LUTS was assessed using the International Prostate Symptom Score (IPSS). Potential factors associated with LUTS including age, ethnicity, education, history of hypertension, diabetes and hypercholesterolemia, height, weight, and prostate volume were evaluated using univariable and multivariable analyses., Results: There were 506 (50%) men found to have moderate-to-severe LUTS attaining an IPSS above 7. Overall, nocturia (45.5%) was the most frequently reported symptom. Multivariable analysis showed that age, ethnicity, prostate volume and history of hypertension and hypercholesterolemia were independent factors associated with severity of LUTS (p < 0.05). Considering individual lower urinary tract symptoms, we found a strong association of storage symptom with history of hypertension and hypercholesterolemia. Malay men were significantly bothered by post micturition symptom compared to their Chinese and Indian counterparts. Stratified analyses of LUTS demonstrated a mutually exclusive cardiovascular risk factors profile defined by ethnicity., Conclusion: Severity of LUTS varies between different ethnicities across all age groups. In addition to age and prostate volume, ethnicity and cardiovascular risk factors including hypertension and hypercholesterolemia may also need to be taken into account in managing men with LUTS.

- Abstract
Objectives: To study the baseline PSA profile and determine the factors influencing the PSA levels within a multiethnic Asian setting., Materials and Methods: We conducted a cross-sectional study of 1054 men with no clinical evidence of prostate cancer, prostate surgery or 5α-reductase inhibitor treatment of known prostate conditions. The serum PSA concentration of each subject was assayed. Potential factors associated with PSA level including age, ethnicity, height, weight, family history of prostate cancer, lower urinary tract voiding symptoms (LUTS), prostate volume and digital rectal examination (DRE) were evaluated using univariable and multivariable analysis., Results: There were 38 men (3.6%) found to have a PSA level above 4 ng/ml and 1016 (96.4%) with a healthy PSA (≤4 ng/ml). The median PSA level of Malay, Chinese and Indian men was 1.00 ng/ml, 1.16 ng/ml and 0.83 ng/ml, respectively. Indians had a relatively lower median PSA level and prostate volume than Malays and Chinese, who shared a comparable median PSA value across all 10-years age groups. The PSA density was fairly similar amongst all ethnicities. Further analysis showed that ethnicity, weight and prostate volume were independent factors associated with age specific PSA level in the multivariable analysis (p<0.05)., Conclusion: These findings support the concept that the baseline PSA level varies between different ethnicities across all age groups. In addition to age and prostate volume, ethnicity may also need to be taken into account when investigating serum PSA concentrations in the multiethnic Asian population.

- Abstract
Surgical wound infection after a renal transplant procedure can lead to graft loss in the presence of host immunosuppression and graft exposure to the environment. Early cover of the wound with well-vascularized tissue will facilitate early wound healing and preservation of the graft. The pedicle anterolateral thigh perforator flap is a popular flap used for soft tissue reconstruction in the groin and perineum. We present a case of an anterolateral thigh flap used to cover an exposed transplanted kidney after surgical wound breakdown., (Copyright © 2011 S. Karger AG, Basel.)

- Abstract
The incidence of prostate cancer in Malaysia is still low compared to the west. This may be due to a true low incidence or lower detection rates. Prostate Awareness Campaigns are held on a yearly basis to educate and encourage males over the age of 50 years to have their prostate examined. Such a campaign was organized in 2005 at the national level involving 12 district hospitals. A total of 2770 participants attended the campaign. 38.7% had no urinary symptoms and attended out of curiosity. Among the symptomatic patients, nocturia was the most bothersome in the majority. 84.6% of the participants also had some degree of erectile dysfunction based on the IIEF questionnaire. 10.4% of participants had a PSA > 4 ng/mL. Malay participants had the highest mean PSA level (2.32 ng/mL) and Indian participants the lowest (1.30 ng/mL). 408 participants were called back for biopsy but only 183 agreed to the biopsy. 30 cancers were detected. At present Malaysia will benefit most by continuing to conduct these awareness programmes to educate the public on prostate disease and hopefully in future patients will be less reluctant to have prostate biopsies taken when indicated., (Copyright © 2010 Elsevier Inc.

Objective: To study the attitudes, concerns, perceived impact, coping strategies, knowledge on avian influenza (AI) and personal protection measures, and institutional and personal preparedness for AI among all Indonesian primary healthcare workers (PHW)., Methods: Questionnaire survey of PHW from four public primary healthcare clinics in South Jakarta (n = 333), with Singaporean PHW from 18 such clinics as controls (n = 1321). Twelve focus group discussions with 51 South Jakarta PHW were also conducted. Quantitative and qualitative data were analysed separately with statistical and thematic analysis, respectively, then combined., Results: South Jakarta PHW had positive attitudes but major concerns about contracting AI, difficulties in diagnosing human AI and inadequacy of personal protection provided. South Jakarta PHW are less knowledgeable about AI and use of personal protection equipment, and reported poorer awareness, availability and participation in AI preparation activities. Only 3% of South Jakarta PHW received influenza vaccination in the preceding 6 months and few felt prepared for AI., Conclusions: South Jakarta primary healthcare workers are not well prepared for avian influenza. There is an urgent need to build their primary healthcare capacity to protect them and contain this global health threat.

- Abstract
Introduction: During an avian influenza (AI) pandemic, primary-care physicians (PCPs) are expected to play key roles in the prevention and control of the disease. Different groups of PCPs could have different concerns and preparedness level. We assessed the concerns, perceived impact and preparedness for an outbreak among PCPs in Singapore., Materials and Methods: A cross-sectional survey of PCPs working in private practice (n=200) and public clinics (n=205) from March to June 2006 with an anonymous self-administered questionnaire on concerns (12- items), perceived impact (10 items) and preparedness (10 items) for an outbreak., Results: Two hundred and eighty-five PCPs responded - 149 (response rate: 72.7%) public and 136 (response rate: 67.3%) private. The majority were concerned about risk to their health from their occupation (95.0%) and falling ill with AI (89.7%). Most (82.5%) accepted the risk and only 33 (11.8%) would consider stopping work. For perceived impact, most felt that people would avoid them (69.6%) and their families (54.1%). The majority (81.3%) expected an increased workload and feeling more stressed at work (86.9%). For preparedness, 78.7% felt personally prepared for an outbreak. Public PCPs were more likely to be involved in infection-control activities and felt that their workplaces were prepared., Conclusions: Most PCPs felt personally prepared for an outbreak but were concerned about their exposure to AI and falling ill. Other concerns included social ostracism for themselves and their families. Public PCPs appeared to have a higher level of preparation. Addressing concerns and improving level of preparedness are crucial to strengthen the primary-care response for any AI outbreak.

- Abstract
Hand-assisted laparoscopic nephrectomy (HAL-N) and nephroureterectomy (HAL-NU) were introduced to bridge the gap between open and laparoscopic surgery. This newer technique has the benefits of both laparoscopic and open surgical approaches but has a shorter learning curve and decreased operative time compared to laparoscopic surgery. A review of our 2-year experience showed that for the seventeen cases of HAL-N that was performed, the mean operative time was 187.8 minutes while the mean length of hospital stay was 4.1 days. For the two HAL-NU cases, the mean operative time was 415 minutes while the mean length of hospital stay was 5.5 days. Only one complication occurred and it was an incisional hernia at the hand-port site. There was no recurrence for the carcinoma cases. Our experience shows that this technique is feasible and safe.

- Abstract
Introduction: With the potential threat of an avian influenza (AI) pandemic, healthcare workers (HCWs) are expected to play important roles, and they encounter significant stress levels from an expected increase in workload. We compared the concerns, perceived impact and preparedness for an AI pandemic between HCWs working in public primary care clinics and a tertiary healthcare setting., Materials and Methods: An anonymous, self-administered questionnaire was given to 2459 HCWs working at 18 public polyclinics (PCs) and a tertiary hospital (TH) in Singapore from March to June 2006. The questionnaire assessed work-related and non-work-related concerns, perceived impact on personal life and work as well as workplace preparedness., Results: We obtained responses from 986 PC and 873 TH HCWs (response rate: 74.6% and 76.7%). The majority in both groups were concerned about the high AI risk from their occupation (82.7%) and falling ill with AI (75.9%). 71.9% accepted the risk but 25.5% felt that they should not be looking after AI patients with 15.0% consider resigning. HCWs also felt that people would avoid them (63.5%) and their families (54.1%) during a pandemic. The majority expected an increased workload and to feel more stressed at work. For preparedness, 74.2% felt personally prepared and 83.7% felt that their workplaces were prepared for an outbreak. TH HCWs were more likely to be involved in infection-control activities but the perception of infection-control preparedness in both groups was high (>80.0%)., Conclusions: HCWs in both public primary and tertiary healthcare settings felt prepared, personally and in their workplaces, for a pandemic. Their main concerns were risks of falling ill from exposure and the possibility of social ostracism of themselves and their families. Preparedness levels appeared high in the majority of HCWs. However, concerns of HCWs could affect their overall effectiveness in a pandemic and should be addressed by incorporating strategies to manage them in pandemic planning.

Objective: To examine the characteristics, management practices and outcomes of patients presenting with symptoms of benign prostatic hyperplasia (BPH) in Asia, with a focus on comorbidities and sexuality., Patients and Methods: In this multinational prospective observational registry, eligible patients with BPH attending a urology clinic for the first time were enrolled. Details of comorbidities, sexuality and symptoms of BPH were collected through the International Prostate Symptom Score (IPSS), International Index of Erectile Dysfunction-5 (IIEF-5) and the Danish Prostate Symptom Score (DAN-PSS-1) questionnaires. The follow-up was scheduled at 1-3 or 3-6 months, depending on the treatment., Results: In 994 men aged 40-88 years the most common comorbidities were hypertension (38%) and obesity (36%). Nocturia was the most common symptom for consultation. A previous episode of acute urinary retention (AUR) was recorded in 12%. About 90% of the men had moderate-to-severe lower urinary tract symptoms (LUTS), and the severity increased with age. Sexual dysfunction was reported by 82%, and it correlated with the severity of LUTS. Of 918 sexually active men, only 20% had normal erectile function; 36%, 19% and 25% reported severe, moderate and mild erectile dysfunction (ED), respectively. BPH medication was started in 78%, 9% had surgery, and in 13% an approach of watchful waiting was adopted. In all, 89% of patients completed the follow-up. The symptoms of BPH resolved in 93% after surgery, in 83% on BPH medication and in 34% of those on 'watchful waiting'. Surgery, which led to a mean reduction of 17.0 IPSS points, was the most effective in improving LUTS. Improvement on the DAN-PSS-1 items of reduced erection and reduced ejaculation was higher with medication, while surgery led to better outcomes on the DAN-PSS-1 item of pain/discomfort on ejaculation. For ED, from baseline to after treatment, the mean IIEF-5 scores changed from 19.1 to 18, from 14.2 to 14.8, and from 4.5 to 5.5 for those with mild, moderate and severe ED at baseline, respectively. Only 2.3% of patients had an episode of AUR while on treatment. About 5.5% of patients on BPH medication and 6% of surgical patients reported adverse events., Conclusion: Asian patients with BPH usually present with LUTS; sexual dysfunction is also very common. BPH medication is the most frequent treatment approach, followed by watchful waiting and surgery. Medication and surgery resulted in a greater reduction of LUTS and improvement in sexual dysfunction than watchful waiting. As Asian men remain sexually active even at advanced ages, sexual function should be assessed and discussed with the patient before deciding the management strategy for LUTS associated with BPH.

- Abstract
Objective: To describe and compare the patterns of nocturia in Asian and Caucasian men presenting with lower urinary tract symptoms (LUTS), and to identify associations or correlations between LUTS and variables from a frequency-volume chart (FVC), as nocturia is common among men with LUTS, and analysis of FVCs shows nocturnal polyuria and reduced nocturnal bladder capacity (NBC) as the predominant causes in Western patients, but there are few comparisons with other ethnic groups., Patients and Methods: Consecutive men aged > or = 40 years, presenting with LUTS and nocturia to an Asian and a Caucasian tertiary centre, were recruited prospectively. The men completed the International Prostate Symptom Score and a 3-day FVC. Men having had bladder outlet surgery and/or receiving anticholinergics were excluded. We computed the nocturia ratio, i.e. the nocturnal urine volume/ 24-h urine volume, nocturia index, predicted nocturnal voids and NBC index (NBCI), and analysed comparisons and correlations., Results: In all, 93 Asian and 200 Caucasian men were recruited prospectively, with a similar age and overall severity of LUTS. The nocturia ratio was larger in the Caucasian men, whereas the NBCI was larger in the Asians (P < 0.001). The prevalence of nocturnal polyuria in men aged > or =60 years (nocturia ratio > or =0.3) was significantly higher in the Caucasian population. Conversely, the prevalence of reduced NBC appeared to be higher in the Asians (based on a NBCI of >2; P < 0.001)., Conclusions: The patterns of nocturia and FVC variables differed significantly in age-matched Asian and Caucasian groups. There are also possible ethnic differences in the causes of nocturia, with nocturnal polyuria being more prevalent in Caucasians.

- Abstract
Percutaneous nephrolithotomy (PCNL) remains the treatment of choice for staghorn renal calculi. Many reports suggest that laparoscopy can be an alternative treatment for large renal stones. We wished to evaluate the role and feasibility of laparoscopic extended pyelolithotomy (REP) for treatment of staghorn calculi. Thirteen patients underwent REP for treatment of staghorn calculi over a 12-day period. Twelve patients had partial staghorn stones and one had a complete staghorn stone. All patients had pre-operative and post-operative imaging including KUB and computed tomography. All procedures were completed robotically without conversion to laparoscopy or open surgery. Mean operative time was 158 min and mean robotic console time was 108 min. Complete stone removal was accomplished in all patients except the one with a complete staghorn calculus. Estimated blood loss was 100 cc, and no patient required post-operative transfusion. REP is an effective treatment alternative to PCNL in some patients with staghorn calculi. However, patients with complete staghorn stones are not suitable candidates for this particular technique.

- Abstract
The occurrence of urinary bladder paragangliomas is rare. A 12-year-old Chinese girl who presented with history of blurring of vision was found to have grade IV hypertensive retinopathy. Investigations revealed a phaeochromocytoma on the posterior wall of the urinary bladder. A partial cystectomy with right ureter reimplantation was undertaken and her hypertension was promptly controlled. The diagnosis and management of this rare tumour is discussed.

- Abstract
Objective: To determine if a volume-adjusted increase in the number of biopsy cores could detect more prostate cancers than the standard sextant biopsy alone, without increasing morbidity, and to determine its applicability in Malaysian patients, as a standard sextant biopsy misses 20-25% of prostate malignancies., Patients and Methods: In a prospective randomized study of patients undergoing transrectal ultrasonography (TRUS)-guided biopsy for a prostate-specific antigen (PSA) level of 4-20 ng/mL without abnormal digital rectal examination (DRE), the men were divided into five main groups (A-E) with prostate volumes of <20, 20-40, 40-60, 60-80 and >80 mL, respectively. Patients in groups B-E were randomized into sextant (B1 to E1) and increased biopsy-core subgroups, i.e. B2 (eight cores), C2 (10 cores), D2 (12 cores) and E2 (14 cores). The morbidity profile was also evaluated during and after TRUS biopsy, assessing a pain score, rectal bleeding, haematuria, haemospermia and development of fever. In all, 132 patients were recruited (mean age 67.8 years; mean PSA 9.41 ng/mL)., Results: The overall cancer detection rate was 24% (32 men). Taking more cores detected 65.5% of cancers, and the sextant biopsy 34.5% (P = 0.0025), but did not increase the overall morbidity., Conclusions: The volume-adjusted, increased-core regimen significantly increased the positive biopsy rate of TRUS-guided prostate biopsies with no added morbidity.
