Authors: Tay Mindy KX , Lee Joyce YC , Wee Ian YJ , Oh Helen ML
Published: January 2023

Introduction: Urinary tract infections remain one of the most frequently encountered acquired complications in an intensive care unit (ICU). The objective of this study was to determine the incidence, risk factors, microbial sensitivity patterns, and clinical outcomes of patients with UTIs acquired during their admission to an ICU in an acute care hospital in Singapore. Materials and Methods: This was a 14-week prospective study. All ICU patients ≥18 years who remained in the ICU for ≥48 hours were eligible for this study. Patients were reviewed daily and the presence of an ICU-acquired UTI was identified via urinary microscopic examination or culture results. Other data collected included patient demographics, ICU admission criteria, concomitant illnesses, presence of invasive lines, microbial sensitivity and treatment outcomes. Results: Thirty-five (13.7%) cases of ICU-acquired UTI occurred in 256 separate ICU admissions. The most common micro-organisms isolated were Candida spp. (34%). Female gender and prior exposure to antibiotics were independent risk factors for developing an ICU-acquired UTI (P <0.01). Both mean length of ICU stay and duration of catheterisation were significantly longer for patients with ICU-acquired UTI (P <0.001). The mortality rate of patients with ICU-acquired UTIs (12.1%) was slightly higher than those without (9.9%). Conclusions: The incidence of ICU-acquired UTIs was similar to figures reported for nosocomial UTIs from the previous studies. Significant risk factors for developing an ICU-acquired UTI were female gender and history of antibiotic exposure prior to ICU admission. The insignificant link between ICU-acquired UTI and mortality requires further investigation in larger cohorts.

Published: January 2023

Introduction: 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. Materials and Methods: 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. Results: 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 re diction 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. Conclusion: 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.

Authors: Huang Jingjing , Liu Xing , Wu Ziqiang , Cao Dan , Sadda Srinivas
Published: January 2023

Introduction: We studied the automated intraretinal segmentation on Fourier domain optical coherence tomography (OCT). Materials and Methods: Thirty eyes from 30 normal subjects were studied using the RTVue-100. Both radial and raster scan protocol were performed 3 times on each subject. The OCT software performs automated intraretinal segmentation and provides macular thickness measurements. Results: Both scanning protocols provide reproducible inner, outer and full retinal thickness measurements. The inner, outer and full retinal thicknesses at the foveal central subfield were 67.31 ± 12.27 μm, 151.67 ± 12.96 μm, 219.33 ± 23.19 μm, respectively by the raster scan, and 63.27 ± 10.37 μm, 147.07 ± 14.54 μm, 209.89 ± 21.80 μm, respectively by the radial scan. Macular regional variations were consistently observed. The raster scan protocol gives greater retinal thickness measurements than the radial scan protocol (P <0.05), but the latter yields slightly more reproducible results. Conclusions: Fourier domain OCT equipped with the ability to perform automatic intraretinal segmentation is a convenient tool in studying diseases that may differentially affect various parts of the retina. However, the establishment of normative values can be complicated by different scanning protocols, devices used, methods of data presentation and definition of intraretinal boundaries.

An Eight Year Review of Exercise-related Cardiac Arrests
Authors: Cheah Si Oon , Ong Marcus EH , Chuah Matthew BF
Published: January 2023

Introduction: Exercise-related cardiac arrest is uncommon, however it is devastating when it occurs in otherwise healthy adults. This study aims to identify the characteristics of exercise-related cardiac arrest in the study population and estimate the overall survival rate. Materials and Methods: This is a retrospective observational study of exercise-related cardiac arrest in Singapore. Patients with exercise-related out of hospital cardiac arrest (OHCA) were selected from the Cardiac Arrest and Resuscitation Epidemiology (CARE) database, which is a prospective cardiac arrest registry, derived from ambulance records, emergency department and hospital discharge records. Patient characteristics, cardiac arrest circumstances and outcomes were studied. Results: Fifty-five cases of exercise-related cardiac arrests were identified from December 2001 to January 2008. Mean age was 50.9 years with a male predominance of 96.4%. Eighty percent of the exercise-related cardiac arrests were witnessed, however only 58.2% of the patients received bystander cardiopulmonary resuscitation (CPR). The first presenting rhythm was ventricular fibrillation (VF) in 40% of the patients, followed by asystole (38.2%). Of 96.2% of the patients who died from cardiac causes, coronary artery disease was the main etiology for 54%. The 30-day survival rate was 5.5%. Conclusion: We found that exercise-related cardiac arrest causes significant mortality in our community. Increased CPR training among the public, easy access to defibrillators and faster emergency medical service (EMS) response time could improve the outcome of exercise-related cardiac arrests. A comprehensive pre-participation screening for competitive exercises should be outlined for primary prevention of exercise-related cardiac arrest. A better reporting system for exercise-related cardiac arrest is needed.

Authors: Salazar Marlon , Ceranto Ribeiro Luís Felipe
Published: January 2023

O consumo de energia elétrica é um dos principais indicadores de desenvolvimento e bem-estar de uma população, logo, as variáveis que determinam este consumo são de grande importância. Este trabalho tem como objetivo decompor o consumo de energia elétrica residencial entre os estados brasileiros, além disso, buscar-se-á verificar o impacto da epidemia de Coronavírus sobre o consumo de energia residencial. Para tanto, utiliza-se a metodologia de decomposição de índices, conhecida como Index Decomposition Analysis (IDA), cujo objetivo é decompor o consumo de energia elétrica residencial em três efeitos, são eles: Efeito Intensidade, Efeito População e Efeito Regional. Os resultados obtidos denotam que o Efeito Intensidade, ou seja, variação do consumo de energia elétrica mediante a variação do consumo per capita, apresentou a maior influência sobre o consumo de energia, além disso, para apenas dois estados, este efeito não foi o mais importante. Já com relação ao impacto da pandemia de Coronavírus, não foi possível determinar a influência desta sobre o consumo, haja vista que apenas o ano de 2020 foi analisado, contudo, o ano de 2020 apresentou o maior aumento (variação) do consumo de energia desde 2015, mesmo apresentando alta expressiva do desemprego e redução da renda do trabalho.
