RESUMO
BACKGROUND: Load carriage imposes high physical stresses on the human body, increasing the risk of injuries. This study assessed the effectiveness of a passive military exoskeleton in off-loading the weight placed on the body during heavy load carriage under static standing and dynamic walking conditions. METHODS: Eight full-time regular personnel of the Singapore Armed Forces enrolled in the study. Static loading tests included nine trials of 10-s quiet standing while carrying different loads (0-55 kg) with and without the exoskeleton. For dynamic loading, participants walked on a treadmill on flat, inclined, and declined surfaces while carrying two different loads (25 kg, 35 kg) with and without the exoskeleton. In-shoe normal ground reaction forces (GRF) were recorded during quiet standing and treadmill walking. Differences in total force with and without the exoskeleton during static loading were compared using Wilcoxon one-sample signed ranked tests against zero (no weight off-load) as a reference. Statistical parametric mapping test was used to compare the walking in-shoe GRF-time series with and without exoskeleton use for each load and surface condition. RESULTS: Exoskeleton use was effective in off-loading loads of 2.3-13.5 kg during static quiet standing but the response varied substantially across loads and among the participants. Statistical analysis revealed no meaningful differences in the walking in-shoe GRF with and without exoskeleton use. The results were largely consistent across flat, inclined, and declined surfaces, and both 25-kg and 35-kg loads. CONCLUSIONS: The passive military exoskeleton was effective in off-loading some load from the human body during static quiet standing but not dynamic walking on flat and sloped surfaces. The varied response across loads and participants calls for better design and fitting of the military exoskeleton to individual users.

Background: A high incidence of venous thromboembolism (VTE) in COVID-19 has led to international recommendations for thromboprophylaxis. With limited data on Asian patients with COVID-19, the role of thromboprophylaxis remains unclear. Objectives: To investigate the in-hospital incidence of VTE in an Asian COVID-19 cohort, describe the VTE trend through successive COVID-19 waves (wild-type, delta, and omicron), and characterize the risk factors for VTE. Methods: We performed a retrospective observational cohort study of hospitalized COVID-19 adults from January 2020 to February 2022. Objectively confirmed VTE were reviewed to obtain VTE incidence and trend. Subset analysis of critical (intensive care), moderate (oxygen supplementation), and mild cases hospitalized ≥5 days was performed to investigate risk factors and in-hospital hazards of VTE. Results: Sixteen VTE events occurred among 3574 patients. Overall, VTE incidence was 0.45%, or 0.21% in mild, 3.60% in moderate, and 5.38% in critical infection. The maximum cumulative risk of VTE was 1.14% at 14 days for mild, 8.13% at 21 days for moderate, and 11.55% at 35 days for critical infection. Thromboprophylaxis use in mild, moderate, and critical cases was 5.7%, 28.8%, and 81.7%, respectively. In multivariable analysis, the severity of infection remained the strongest independent predictor of VTE. Compared with mild infection, the relative risk was 8.26 (95% CI, 2.26-30.16) for critical infection and 6.29 (95% CI, 1.54-25.67) for moderate infection. Conclusion: Overall, VTE incidence in Asian patients with COVID-19 is <1% across successive waves. Patients with moderate and critical infections are at greater risk for VTE and should be considered for routine thromboprophylaxis.
RESUMO
BACKGROUND: The conventional approach to treatment for Paget's disease of the breast has been mastectomy, but there is an increasing trend to consider breast-conserving surgery (BCS) followed by radiotherapy (RT) in these patients. This study aimed to provide an updated systematic review and meta-analysis comparing outcomes after BCS with RT versus mastectomy in the treatment of Paget's disease of the breast. METHODS: Studies before May 2021 were included. Primary outcomes were overall survival and local recurrence. Separate analyses of Paget's disease associated with ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) were undertaken. Meta-regression was used to adjust for imbalance in the proportion of IDC among patients selected to undergo BCS versus mastectomy. RESULTS: Overall survival in patients with Paget's disease who underwent BCS with RT was higher than for those who underwent mastectomy with pooled mortality hazard ratio (HR) of 0.68, (95% per cent c.i. 0.45 to 1.01). Patients with Paget's disease with DCIS had higher overall survival after BCS with or without RT versus mastectomy, with adjusted HR of 0.14 (0.10 to 0.20) and 0.28 (0.22 to 0.36), respectively. For patients with Paget's disease and IDC, overall survival was lower for BCS with or without RT versus mastectomy, with adjusted HR of 0.84 (0.57 to 1.25) and 1.64 (1.04 to 2.58), respectively. In Paget's disease and IDC, local recurrence risk was much higher for BCS with RT, RR 26.8 (1.60 to 456) versus without RT, RR 51.8 (6.80 to 391). In patients with Paget's disease and DCIS, risk of local recurrence versus mastectomy was lower for BCS with RT 0.72 (0.11 to 4.50) but slightly higher for BCS alone 1.38 (0.09 to 21.20). CONCLUSION: BCS with RT may be a comparable treatment alternative to mastectomy for patients with Paget's disease with DCIS, and for selected patients with Paget's disease and IDC.
RESUMO
The loadsol® wireless in-shoe force sensors can be useful for in-field measurements. However, its accuracy is unknown in the military context, whereby soldiers have to carry heavy loads and walk in military boots. The purpose of this study was to establish the validity of the loadsol® sensors in military personnel during loaded walking on flat, inclined and declined surfaces. Full-time Singapore Armed Forces (SAF) personnel (n = 8) walked on an instrumented treadmill on flat, 10° inclined, and 10° declined gradients while carrying heavy loads (25 kg and 35 kg). Normal ground reaction forces (GRF), perpendicular to the contact surface, were simultaneously measured using both the loadsol® sensors inserted in the military boots and the Bertec instrumented treadmill as the gold standard. A total of eight variables of interest were compared between loadsol® and treadmill, including four kinetic (impact peak force, active peak force, impulse, loading rate) and four spatiotemporal (stance time, stride time, cadence, step length) variables. Validity was assessed using Bland-Altman plots and 95% Limits of Agreement (LoA). Bias was calculated as the mean difference between the values obtained from loadsol® and the instrumented treadmill. Results showed similar force-time profiles between loadsol® sensors and the instrumented treadmill. The bias of most variables was generally low, with a narrow range of LoA. The high accuracy and good agreement with standard laboratory equipment suggest that the loadsol® system is a valid tool for measuring normal GRF during walking in military boots under heavy load carriage.

OBJECTIVES: This paper documents our experience and outcomes of using a relatively new endovascular rotational thrombectomy device for salvage of thrombosed vascular access. METHODOLOGY: A retrospective study reviewing patients with thrombosed native AVF or AVG who underwent endovascular declotting using a rotational thrombectomy device between November 2018 and May 2020 at a tertiary university hospital in Southeast Asia. We evaluated demographics, procedural data, technical and procedural success, patency rates and complications. RESULTS: A total of 40 patients underwent single session endovascular declotting of thrombosed vascular access. The mean follow-up period was 21.6 months (range 13.4-31 months). The technical success was 92.5% and clinical success was 80%. About 50% of patients had concomitant thrombolysis for pharmacomechanical thrombectomy. One patient had a myocardial infarction during the post-operative period. There were no other major complications within 30 days. The primary patency was 45.5% at 6 months and 22.7% at 12 months. Assisted primary patency was 68.1% at 6 months and 61.6% at 12 months, which was maintained up to 2 years. The secondary patency was 84.1% at 6 and 12 months. CONCLUSION: Our study shows that rotational thrombectomy device for single session thrombectomy of thrombosed arteriovenous fistulas and grafts is safe and effective. A high technical and clinical success rate was achieved, with low complication rates and specific advantages compared to other techniques, including reduced length of hospital stay. Our reported mid-term outcomes are reasonable with an assisted primary patency of 62% at 12 and 24 months. The use of newer techniques and novel dedicated thrombectomy devices show promise.

INTRODUCTION: Institutional surgical antibiotic prophylaxis (SAP) guidelines are in place at all public hospitals in Singapore, but variations exist and adherence to guidelines is not tracked consistently. A national point prevalence survey carried out in 2020 showed that about 60% of surgical prophylactic antibiotics were administered for more than 24 hours. This guideline aims to align best practices nationally and provides a framework for audit and surveillance. METHOD: This guideline was developed by the National Antimicrobial Stewardship Expert Panel's National Surgical Antibiotic Prophylaxis Guideline Development Workgroup Panel, which comprises infectious diseases physicians, pharmacists, surgeons and anaesthesiologists. The Workgroup adopted the ADAPTE methodology framework with modifications for the development of the guideline. The recommended duration of antibiotic prophylaxis was graded according to the strength of consolidated evidence based on the scoring system of the Singapore Ministry of Health Clinical Practice Guidelines. RESULTS: This National SAP Guideline provides evidence-based recommendations for the rational use of antibiotic prophylaxis. These include recommended agents, dose, timing and duration for patients undergoing common surgeries based on surgical disciplines. The Workgroup also provides antibiotic recommendations for special patient population groups (such as patients with ß-lactam allergy and patients colonised with methicillin-resistant Staphylococcus aureus), as well as for monitoring and surveillance of SAP. CONCLUSION: This evidence-based National SAP Guideline for hospitals in Singapore aims to align practices and optimise the use of antibiotics for surgical prophylaxis for the prevention of surgical site infections while reducing adverse events from prolonged durations of SAP.

There is a paucity of effective intervention tools for overweight/obese women to assess, guide and monitor their eating behavior. This study aimed to develop a lifestyle intervention tool, assess its acceptability and usefulness, and verify its construct validity in overweight/obese women. The 6P tool (Portion, Proportion, Pleasure, Phase, Physicality, Psychology) was developed and 15 women with a body mass index (BMI) ≥ 25 kg/m2 were interviewed to assess its perceived acceptability and usefulness. Subsequently, the revised 6P tool was tested in 46 women with a BMI ≥ 25 kg/m2. The Three-Factor Eating Questionnaire (TFEQ), International Physical Activity Questionnaire-Short (IPAQ), and weight were measured at baseline and one-month. Most participants were satisfied with the presentation of the 6P tool (86.8%), and agreed it was useful in guiding healthy eating (81.6%) and raising awareness of eating behavior (97.4%). There were significant improvements in cognitive restraint (p = 0.010) and disinhibition (p = 0.030) (TFEQ), portion size (P1), pleasure behaviors (P3), and total composite 6P score (p < 0.001). However, there was no significant reduction in weight or increase in physical activity. The 6P tool is acceptable and presents with good validity for assessing lifestyle behaviors.

BACKGROUND AND AIM: Endoscopic retrograde cholangiopancreatography (ERCP), with interval laparoscopic cholecystectomy (LC), is the most common treatment approach for common bile duct (CBD) stones. However, recent studies show that single-stage laparoscopic CBD exploration (LCBDE) is safe and feasible. Three-dimensional (3D) laparoscopy enhances depth perception and facilitates intracorporeal suturing. The application of 3D technology for LCBDE is emerging, and we report our case series of 3D LCBDE. METHODS: We audited the 27 consecutive 3D LCBDE performed from July 2017 to January 2020. We have a liberal policy for magnetic resonance cholangiopancreatography (MRCP) in patients with deranged liver function tests (LFT). All CBD explorations were done through choledochotomy with a 5 mm flexible choledochoscope and primarily repaired with an absorbable barbed suture without a stent or T-tube. RESULTS: The mean age of patients was 68 (range 44-91) years, and 12 (44%) were male. The indications for surgery were choledocholithiasis 67% (n=18), cholangitis 22% (n=6), and gallstone pancreatitis 11% (n=3). About 67% (n=18) had pre-operative ERCP. About 37% (n=10) had pre-operative biliary stent. Pre-operative MRCP was done in 74% (n=20), and the mean diameter of CBD was 14.5 mm (range 7-30). The median operative time was 160 (range 80-265) min. The operative drain was inserted in 18 patients. One patient each (4%) had a bile leak and a retained stone. There was no open conversion, readmission, or mortality. CONCLUSION: 3D LCBDE with primary repair by an absorbable barbed suture is safe and feasible. RELEVANCE FOR PATIENTS: This paper emphasized that one stage LCBDE should be a treatment option which is comparable with two stage ERCP followed by LC to treat CBD stones. In addition, 3D technology and barbed sutures use in LCBDE are safe and useful.

BACKGROUND: Arterial and venous thrombosis are reported to be common in critically ill COVID-19 patients. METHOD AND RESULTS: This is a national multicenter retrospective observational study involving all consecutive adult COVID-19 patients who required intensive care units (ICU) admission between 23 January 2020 and 30 April 2020 in Singapore. One hundred eleven patients were included and the venous and arterial thrombotic rates in ICU were 1.8% (n = 2) and 9.9% (n = 11), respectively. Major bleeding rate was 14.8% (n = 16). CONCLUSIONS: Critically ill COVID-19 patients in Singapore have lower venous thromboembolism but higher arterial thrombosis rates and bleeding manifestations than other reported cohorts.
RESUMO
The most apparent practical advantage of del Nido cardioplegia (DNC) is that it allows the surgeon a longer arrest period before a subsequent dose is needed, as opposed to the conventional St. Thomas' cardioplegia solution where the recommended ischemic time is â¼15-20 minutes. In this study, we explored the incidence of arrhythmia after cross-clamp removal as a surrogate for a safe myocardial ischemic time with the use of DNC in adult heart surgery. A total of 113 patients who had undergone heart valve repair and/or replacement surgery at the National University Hospital, Singapore, were investigated. This single-center retrospective study was conducted on a population where DNC had been used for myocardial protection between January 2017 and April 2019. Cardioplegia ischemic time interval groups were not significant predictors of postoperative arrhythmia, defibrillation, and intraoperative intra-aortic balloon pump usage. Crude comparison of postoperative outcomes showed no significant differences in any other postoperative variables, including mortality and total hospital stay. From the results of the present study, it appears that there is no optimal ischemic time interval for the administration of DNC within a 120-minute time period. It is likely that DNC has a redosing interval of, and may provide adequate myocardial protection, for up to 120 minutes.

BACKGROUND: The world's most catastrophic epidemic thunderstorm asthma event (ETSA) affected Melbourne in 2016. Little is known about the natural history of individuals affected by such extreme events. OBJECTIVE: In this single center prospective 3-year longitudinal study, symptomatology and behaviors of individuals affected by ETSA were assessed. METHODS: Standardized telephone questionnaire was used to evaluate frequency of asthma symptoms, inhaled corticosteroid preventer use, asthma action plan ownership, and healthcare utilization. Questionnaires were administered at 12, 24, and 36 months after 2016 ETSA. Subgroup analyses of the 'current', 'past', 'possible,' and 'no asthma' subgroups were also conducted. RESULTS: Two hundred and eight, 164, and 112 completed questionnaires were analyzed in 2017, 2018, and 2019, respectively. Seventy to eighty five percent of respondents reported ongoing asthma symptoms in any given year, of which 20%-28% experienced weekly symptoms. Nearly 50% of respondents were prescribed preventers, with approximately 45% adherent at least 5 days a week. Less than 40% had an asthma action plan and 15%-20% sought urgent medical attention for asthma over the follow-up period. Among 106 individuals with 3 consecutive years of completed questionnaires, those with no prior doctor diagnosis of asthma were significantly more likely to be asymptomatic on follow-up than those with a prior doctor diagnosis of asthma (p = 0.02). Subgroup analyses suggest that large proportions of respondents with 'past' and 'no asthma' continue to remain symptomatic throughout the 36-month period. CONCLUSION: In individuals affected by ETSA, we found evidence of ongoing loss of asthma control in those with previously well controlled asthma, and the persistence of symptoms suggestive of asthma in those with no history or symptoms suggestive of prior asthma, even after 36 months from initial ETSA. Low rates of inhaler adherence and asthma action plan ownership may contribute to increased morbidity and mortality from future ETSA events. Further research is required to confirm these findings.
RESUMO
Remote cerebellar hemorrhage (RCH) is a rare yet potentially fatal complication of supratentorial and spinal surgery, where there has been either intentional or accidental breach of the dura. We present a case of RCH following a L4-5 decompression laminectomy complicated by an intraoperative dural tear which was detected and repaired at the time of surgery. Despite prompt intra-operative repair of the dura, there was persistent cerebrospinal fluid leak as evidenced by a high subfascial epidural drain output which resulted in bilateral intraparenchymal cerebellar hemorrhage. The patient was managed conservatively and recovered without neurological deficits.

BACKGROUND: The Victorian Audit of Surgical Mortality (VASM) investigates all surgically related deaths in Victoria, Australia, as a surgical educational activity aimed to make surgery safer. Whilst data collected within the audit are regularly reviewed for accuracy, there has never been a review of the data provided from health services. METHODS: Two-year death data provided by one Victorian health service were reviewed. Hospital notes for 4 months of each year were analysed to assess patients dying under surgical care. These data were compared to referrals to the VASM over the same period. RESULTS: Of the 3907 patient deaths recorded, 35.1% were reviewed. During their final admission, 178 (13%) patients underwent a procedure (93 medical and 85 surgical). Only 29.2% of these were recorded in the health service data set. Eighteen patients died under the care of a surgeon without a procedure, meaning that 103 deaths should have been reported to the VASM of which only 55.3% (57/103) were reported. CONCLUSION: There were major errors in the health service database resulting in under-reporting of deaths to the VASM which could have education and policy repercussions. For improvements to the safety and quality of health services, it is critical that all deaths are accurately recorded by health services and reported to the relevant bodies with internal verification processes.

Background Sex hormones initiate profound physical and physiological changes during the pubertal process, but to what extent are they responsible for continuing the body composition changes of late adolescence and what happens to body composition on sudden sex hormone withdrawal? Methods Thirty-six healthy, phenotypically and chromosomally normal late and post-pubertal individuals aged 15-17 years with gender dysphoria (transgirls - birth-registered males identifying as female n = 11; and transboys - birth-registered females identifying as male n = 25) underwent Tanita body composition analysis at 0, 6 and 12 months during reproductive hormone suppression with Triptorelin as part of the standard therapeutic protocol. Results and conclusions In the transgirl cohort, paired t-test analysis demonstrated a significant decrease in height and lean mass standard deviation scores over the 12-month period, going against an expected trajectory over that time. In contrast, oestrogen suppression appeared not to affect the body composition of transboys; their measurements were not significantly different at baseline and after 12 months of treatment. The withdrawal of sex hormone secretion does not appear to have a significant impact on female post-pubertal body composition, in contrast to that seen at the menopause. This suggests that other factors may preserve normal body balance in adolescents in the absence of sex steroids.

BACKGROUND: The prevalence of hepatitis C virus (HCV) has been reported to be high among people experiencing homelessness. People who are homeless often have multiple needs that may take precedence over HCV testing and treatment. We quantitatively evaluated the outcomes of a service providing HCV treatment to people attending homeless services. METHODS: Clients attending homeless services were referred to a nurse specialising in HCV-related care. The nurse provided HCV testing, education and case-management while prescriptions were provided by an affiliated doctor. Logistic regression was used to explore factors associated with treatment commencement. RESULTS: Fifty-two clients referred (78%) underwent testing, thirty-nine were HCV-RNA positive among whom 18 (46%) reported sleeping rough and 29 (74%) reported injecting drug use; 66% had injected less than three months ago. Twenty-four (62%) clients commenced treatment, of whom thirteen (54%) had a sustained virological response test; all were cured. Treatment commencement was lower among people who reported sleeping rough (aOR 0.15, 95%CI 0.029-0.73). There was no difference in treatment commencement based on injecting drugs (aOR 1.06, 95%CI 0.21-5.2). CONCLUSION: Most clients' commenced treatment and the majority were successfully cured using a dedicated nursing service. Clients who reported sleeping rough may still face personal and/or system level barriers to HCV treatment.

BACKGROUND: Carbapenem-resistant (CR), extremely drug-resistant (XDR), and pan-drug-resistant (PDR) Acinetobacter baumannii and Pseudomonas aeruginosa pose a huge clinical threat. This study reviews the impact of control groups on the association of antecedent antibiotic use and the acquisition of CR/XDR/PDR A. baumannii and P. aeruginosa. METHODS: Studies investigating the role of antibiotics as a risk factor for CR/XDR/PDR A. baumannii and P. aeruginosa acquisition in adult hospitalized patients from 1950 to 2016 were identified in the databases. These were divided into two groups: antibiotic-resistant versus antibiotic-sensitive pathogens (group I); antibiotic-resistant versus no infection (group II). A random-effects model was performed. RESULTS: Eighty-five studies (46 A. baumannii, 38 P. aeruginosa, and one of both) involving 22 396 patients were included. CR was investigated in 60 studies, XDR in 20 studies, and PDR in two studies. Prior antibiotic exposure was associated with significant acquisition of CR/XDR/PDR A. baumannii and P. aeruginosa in both groups I and II (p<0.05). Antibiotic classes implicated in both groups included aminoglycosides, carbapenems, glycopeptides, and penicillins. Cephalosporin use was not associated with resistance in either group. Fluoroquinolone exposure was only associated with resistance in group I but not group II. CONCLUSIONS: Control groups play an important role in determining the magnitudes of risk estimates for risk factor studies, hence careful selection is necessary. Antibiotic exposure increases the acquisition of highly resistant A. baumannii and P. aeruginosa, thus appropriate antibiotic use is imperative.

Human papillomavirus (HPV) vaccination uptake in Singapore is low among young women. Low uptake has been found to be linked to low awareness. Thus, this study aimed to understand active and passive vaccine information-seeking behavior. Furthermore, guided by the Elaboration Likelihood Model (ELM), this study examined young women's (aged 21-26 years) processing of information they acquired in their decision to get vaccinated. ELM postulates that information processing could be through the central (i.e., logic-based) or peripheral (i.e., heuristic-based) route. Twenty-six in-depth interviews were conducted from January to March 2016. Data were analyzed using thematic analysis. Two meta-themes-information acquisition and vaccination decision-revealed the heuristic-based information processing was employed. These young women acquired information passively within their social network and actively in healthcare settings. However, they used heuristic cues, such as closeness and trust, to process the information. Similarly, vaccination decisions revealed that women relied on heuristic cues, such as sense of belonging and validation among peers and source credibility and likability in medical settings, in their decision to get vaccinated. The findings of this study highlight that intervention efforts should focus on strengthening social support among personal networks to increase the uptake of the vaccine.
