ABSTRACT

INTRODUCTION@#Patients with significant comorbidities have high general anaesthetic risks and are often thought to be undesirable candidates for general anaesthesia and, therefore, surgery. External fixation uses local or regional anaesthesia, and allows patients with significant comorbidities to avoid the risks of general anaesthesia. It has been described to be successful in the management of high-risk patients with intertrochanteric fractures. However, published data have been derived from small case series, and no published literature has attempted to analyse them in totality. This review aims to pool together these case series, and to evaluate the outcomes and complications of external fixation when performed in high-risk patients with intertrochanteric fractures.@*MATERIALS AND METHODS@#The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRSIMA) guidelines. All studies that reported the outcomes of external fixation for intertrochanteric fractures of high-risk patients were included.@*RESULTS@#A total of 13 publications, involving 687 patients, were included in the review. All the studies reported postoperative radiological reduction and complete fracture healing with reduction of limb length discrepancy. One study using parallel placement of proximal fixation screws showed shorter operative duration as compared to convergent placement. Another study mentioned that there was no significant difference in mortality rates between patients with stable fractures and those with unstable fractures who underwent external fixation. All the studies reported a decrease in postoperative immobility, reduction in pain and improvement in clinical outcome hip scores.@*CONCLUSION@#External fixation is promising and useful especially in the management of high-risk patients with intertrochanteric fractures. The procedure can help with radiological reduction of the fracture, reduction of limb length discrepancy, reduction of operative duration, decrease in postoperative immobility, reduction in pain and improvement in clinical outcome hip scores. The procedure is versatile and seems to be able to accommodate both stable and unstable fractures. However, unstable fractures may be associated with greater postoperative morbidity, and it may be worthwhile to prognosticate based on the stability of the patients' fracture for better risk-benefit analysis preoperatively. Shorter operative times can also be achieved through parallel proximal pin placement, without impact on mortality or morbidity.

ABSTRACT

INTRODUCTION@#Diabetes mellitus is a major public health issue in Singapore. To shape healthcare policies for the primary prevention of diabetes, it is crucial to understand Singaporeans' knowledge, attitudes and practices related to diabetes and its prevention. This study aimed to assess the knowledge, attitudes and lifestyles of individuals without diabetes.@*MATERIALS AND METHODS@#A cross-sectional household survey was performed between 31 January to 3 February 2019 to examine knowledge, attitudes and practices related to diabetes. Inclusion criteria of the participants included: 1) Singaporeans/permanent residents, 2) between 30 to 64 years old, and 3) who did not have a diagnosis of diabetes. Logistic and linear regression models were used to analyse the association of knowledge and attitudes with physical activity and diet habits, respectively.@*RESULTS@#Among 806 participants, 72.2% did not meet the Health Promotion Board's physical activity recommendation. Physical activity was associated with better diabetes knowledge (odds ratio [OR] 5.38, 95% confidence interval [CI] = 1.65-17.53, = 0.049), stronger beliefs in diabetes prevention (OR 3.36, 95% CI = 1.02-11.12, = 0.047) and lower levels of worry about diabetes (OR 0.41, 95% CI 0.17-1.00, = 0.049). Neither knowledge nor beliefs or worries about diabetes was associated with diet.@*CONCLUSION@#There is a need to reinforce the importance of physical activity and healthy diet in preventing diabetes. Although improving the knowledge level of diabetes may increase physical activity of the population, it is unlikely to improve dietary choices without effective behavior change interventions.

ABSTRACT

<p><b>INTRODUCTION</b>The near terminal patient with skeletal metastasis may suitably be palliated with an intramedullary nail whereas another patient with good survival potential may benefit from a more extensive resection and reconstructive procedure. In a previous study by the senior author (Nathan et al, 2005), life expectancy in patients operated on for bone metastases correlated with clinical and haematological parameters in a normogram. We performed a cross-cultural comparison to validate this normogram.</p><p><b>MATERIALS AND METHODS</b>We randomly selected 73 patients who had undergone surgery for metastatic bone disease between 28 December 2000 and 11 March 2009. The time to deaths was recorded from hospital records and telephone interviews. Multiple parameters including clinical, radiological and haematological were evaluated for significant prognostic value using Kaplan-Meier survivorship analysis. Statistically significant parameters were entered into a Cox regression model for statistically independent significance. A multi-tier prediction of survival was performed by workers from various levels of seniority.</p><p><b>RESULTS</b>At the time of analysis, there were 40 deaths (55%). Median survival was 15.8 (95% CI, 7.9 to 23.7) months. Kaplan-Meier analysis showed that low haemoglobin (P = 0.0000005), presence of lymph node metastases (P = 0.00008), multiple bone metastases (P = 0.003), presence of visceral metastases, (P = 0.007), low lymphocyte count (P = 0.02) and low serum albumin (P = 0.02) were significantly associated with poor survival. By Cox regression analysis, presence of visceral metastases (P = 0.002), presence of lymph node metastases (P = 0.0002) and low haemoglobin (P = 0.01) were shown to be independent factors in the prediction of survival. Survivorship readings were superimposed onto the previous normogram and found to be similar. Independent blinded use of the normogram allowed good prediction of survival. There was a tendency to underestimate survival when patients survived beyond 1 year of skeletal metastasis.</p><p><b>CONCLUSION</b>Our findings are similar to that of the previous study in showing a relationship between the above-mentioned parameters and survival. This is despite differences in patient demographic characteristics and management protocols. Use of the tools may allow better siting of most appropriate surgery in metastatic bony disease.</p>
