United in Fight against prOstate cancer (UFO) registry: first results from a large, multi-centre, prospective, longitudinal cohort study of advanced prostate cancer in Asia.

OBJECTIVES: To document the management of advanced prostate cancer including diagnosis, prognosis, treatment, and care, in real-world practice in Asia using the United in Fight against prOstate cancer (UFO) registry. PATIENTS AND METHODS: We established a multi-national, longitudinal, observational registry of patients with prostate cancer presenting to participating tertiary care hospitals in eight Asian countries. A total of 3636 eligible patients with existing or newly diagnosed high-risk localised prostate cancer (HRL), non-metastatic biochemically recurrent prostate cancer (M0), or metastatic prostate cancer (M1), were consecutively enrolled and are being followed-up for 5 years. Patient history, demographic and disease characteristics, treatment and treatment decisions, were collected at first prostate cancer diagnosis and at enrolment. Patient-reported quality of life was prospectively assessed using the European Quality of Life-five Dimensions, five Levels (EQ-5D-5L) and Functional Assessment of Cancer Therapy for Prostate Cancer questionnaires. In the present study, we report the first interim analysis of 2063 patients enrolled from study start (15 September 2015) until 18 May 2017. RESULTS: Of the 2063 enrolled patients, 357 (17%), 378 (19%), and 1328 (64%) had HRL, M0 or M1 prostate cancer, respectively. The mean age at first diagnosis was similar in each group, 56% of all patients had extracapsular extension of their tumour, 28% had regional lymph node metastasis, and 53% had distant metastases. At enrolment, 62% of patients had at least one co-morbidity (mainly cardiovascular disease or diabetes), 91.8% of M1 patients had an Eastern Cooperative Oncology Group performance score of <2 and the mean EQ-5D-5L visual analogue score was 74.6-79.6 across cohorts. Treatment of M1 patients was primarily with combined androgen blockade (58%) or androgen-deprivation therapy (either orchidectomy or luteinising hormone-releasing hormone analogues) (32%). Decisions to start therapy were mainly driven by treatment guidelines and disease progression. Decision to discontinue therapy was most often due to disease progression (hormonal drug therapy) or completion of therapy (chemotherapy). CONCLUSION: In the UFO registry of advanced prostate cancer in Asia, regional differences exist in prostate cancer treatment patterns that will be explored more deeply during the follow-up period; prospective follow-up is ongoing. The UFO registry will provide valuable descriptive data on current disease characteristics and treatment landscape amongst patients with prostate cancer in Asia.

Outcomes of warfarinized patients with minor head injury and normal initial CT scan.

OBJECTIVES: We investigated delayed outcomes of patients with minor head injury, warfarin, and a normal initial head computer tomographic (CT) scan finding. METHODS: We conducted a single-center, retrospective study on such patients who were admitted. A second CT was not mandatory. International normalized ratios were classified into subtherapeutic, therapeutic, and supratherapeutic ranges. We traced them 2 weeks after discharge for delayed intracranial hemorrhage (ICH). Primary outcomes were proportions with ICH on second CT, fresh-frozen plasma (FFP) and/or vitamin K administration, and neurosurgical intervention. Secondary outcomes were hospital length of stay and the proportion with ICH 2 weeks after discharge. We explored differences in proportions of ICH during hospital stay among different strata (age ≥65 years, antiplatelet therapy, supratherapeutic international normalized ratio ranges, and FFP administration). Data were analyzed using descriptive statistics. P values less than .05 were considered statistically significant. RESULTS: We recruited 298 patients. Of admissions (N = 295), 11 (3.7%) had a second CT, with one (0.3%) abnormality. There were 7 (2.4%) and 8 (2.7%) patients who received FFP and vitamin K, respectively. One patient (0.3%) required neurosurgical intervention. The median hospital length of stay was 3 (interquartile range, 2) days. No patients reattended 2 weeks after discharge. There were no statistically significant differences in the proportions of ICH during hospital stay among the 4 strata. CONCLUSIONS: Delayed ICH was rare with no predictive factors. Clinical monitoring before deciding on second CT was safe. The optimal period and mode of observation had yet to be determined.

Renal point-of-care ultrasound performed by ED staff with limited training and 30-day outcomes in patients with renal colic.

BACKGROUND AND AIM: Emergency Department (ED) renal point-of-care ultrasound (PoCUS) in renal colic by accredited specialists has good prognostic value. This may not be generalizable to under-resourced EDs. We investigated PoCUS in renal colic in our ED with lesser training. METHODS: We performed a single-centre health records review of adult ED patients with renal colic and PoCUS. Patients were managed by a non-ED specialist/resident doctor with no POCUS accreditation in consultation with an attending. These doctors attended a 3.5-h training session conducted by accredited attendings to examine hydronephrosis. They needed to verify their PoCUS findings with an attending during the first two weeks of their six-month posting before performing it independently. The primary outcome was 30-day urological procedures in hydronephrotic vs. non-hydronephrotic groups. Secondary outcomes were the distribution of primary outcome with grades of hydronephrosis, 30-day ED nephrolithiasis-related reattendances in hydronephrotic vs. non-hydronephrotic groups and its distribution with grades of hydronephrosis. We compared outcomes using Fisher's exact test. We also reported crude odds ratio (COR) and 95% CI of primary outcome between hydronephrotic vs. non-hydronephrotic groups. p values ≤ 0.05 were significant. RESULTS: We recruited 651 patients; 160 (24.6%) without and 491 (75.4%) with hydronephrosis. Rates of grades of hydronephrosis were: mild (76.6%), moderate (13.8%), severe (1.2%) and undifferentiated (8.4%). There was a difference in 30-day urological procedures (rates [95% CI]) in hydronephrotic vs. non-hydronephrotic groups, 11.2 [8.7-14.0]% vs. 2.5 [1.0-6.3]%; p < 0.001; COR (95% CI) 4.9 (1.8-13.8); p = 0.002. Increasing 30-day urological procedural rates were associated with increasing grade of hydronephrosis [no: 2.5%, mild: 7.7%, moderate: 23.5%, severe: 67.0% and undifferentiated: 14.6%; p < 0.001]. No differences occurred in other secondary outcomes. CONCLUSIONS: Renal PoCUS could be performed by non-ED specialist/resident doctors to identify patients without hydronephrosis who rarely required urological intervention. Hydronephrotic patients could benefit from further risk stratification.

ABSTRAIT: CONTEXTE ET OBJECTIF: L'échographie rénale au point de soin (PoCUS) dans les coliques rénales par des spécialistes agréés a une bonne valeur pronostique. Cela peut ne pas être généralisable aux SU sous-financés. Nous avons étudié PoCUS dans les coliques rénales dans notre DE avec une formation moindre. MéTHODES: Nous avons effectué un examen des dossiers médicaux d'un seul centre des patients adultes atteints de coliques rénales et de PoCUS. Les patients étaient pris en charge par un médecin résident/spécialiste non-membre de la DG sans accréditation POCUS en consultation avec un médecin traitant. Ces médecins ont assisté à une séance de formation de 3,5 heures menée par des titulaires accrédités pour examiner l'hydronéphrose. Ils devaient vérifier leurs résultats PoCUS auprès d'un assistant pendant les deux premières semaines de leur affectation de six mois avant de l'effectuer de manière indépendante. Le critère de jugement principal était des procédures urologiques de 30 jours dans les groupes hydronéphrotiques vs non-hydronephrotiques. Les critères de jugement secondaires étaient la distribution du critère de jugement primaire avec les grades d'hydronéphrose, les reattendances liées à la néphrose ED de 30 jours dans les groupes hydronéphrotiques vs non hydronéphrotiques et sa distribution avec les grades d'hydronéphrose. Nous avons comparé les résultats en utilisant le test exact de Fisher. Nous avons également signalé un rapport de cotes brut (RC) et un IC à 95 % du critère de jugement principal entre les groupes hydronéphrotiques et non hydronéphrotiques. Les valeurs de P 0,05 étaient significatives. RéSULTATS: Nous avons recruté 651 patients; 160 (24,6%) sans et 491 (75,4%) avec hydronéphrose. Les taux d'hydronéphrose étaient les suivants : légère (76,6 %), modérée (13,8 %), sévère (1,2 %) et indifférenciée (8,4 %). Il y avait une différence dans les interventions urologiques de 30 jours (taux [IC à 95 %]) dans les groupes hydronéphrotiques par rapport aux groupes non-hydronephrotiques, 11,2 [8,7-14,0] % contre 2,5 [1,0-6,3]%; p < 0,001; RCC (IC à 95 %) 4,9 (1,8-13,8); p = 0,002. L'augmentation des taux de procédures urologiques de 30 jours était associée à l'augmentation du grade d'hydronéphrose [non : 2,5%, léger : 7,7%, modéré : 23,5%, sévère : 67,0% et indifférencié : 14,6%; p < 0,001]. Aucune différence n'est survenue dans les autres critères de jugement secondaires. CONCLUSIONS: La PoCUS rénale pourrait être réalisée par des médecins non spécialistes/résidents de la D pour identifier les patients sans hydronéphrose qui ont rarement nécessité une intervention urologique. Les patients hydronéphrotiques pourraient bénéficier d'une meilleure stratification des risques.

Long-term effect of hyperoxemia during chronic obstructive pulmonary disease exacerbation managed by emergency medical service and emergency department: a prospective, exploratory study.

OBJECTIVE: Long-term effects of hyperoxemia during acute exacerbation of chronic obstructive pulmonary disease (AECOPD) remained unknown. We aimed to explore these effects of hyperoxemia during AECOPD. METHODS: This was an exploratory follow-up study of a cohort with AECOPD managed by Emergency Medical Service and two emergency departments (EDs). Patients were classified as hyperoxemic (PaO2 > 65 mmHg) or nonhyperoxemic (PaO2 ≤ 65 mmHg). Patients discharged from ED/inpatient care were followed up prospectively for 1 year. The primary outcome was 1-year all-cause mortality in hyperoxemic vs. nonhyperoxemic groups. Secondary outcomes were 3-month all-cause mortality and median number of repeat AECOPD hospitalizations within 1 year. We generated Kaplan-Meier curves and compared them using log-rank test. The primary outcome was also analyzed using Cox proportional-hazards model. We reported crude and adjusted hazard ratios, their 95% confidence intervals (CIs) and P values. We adjusted for two a priori predictors of delayed mortality; age ≥ 70 years and repeat AECOPD hospitalizations. RESULTS: A total of 231 patients were analyzed. One-year mortality rates in hyperoxemic vs. nonhyperoxemic groups were 26/137 (19.0%) and 12/94 (12.8%), respectively (P = 0.693). Although Kaplan-Meier curves showed divergent courses favoring nonhyperoxemic group, log-rank test was not statistically significant (P = 0.203). The crude and adjusted hazard ratios (reference: nonhyperoxemic group) were 1.55 (95% CIs, 0.78-3.08; P = 0.207) and 1.57 (95% CIs, 0.79-3.13; P = 0.196), respectively. Secondary outcomes did not differ. CONCLUSIONS: Our study reported no effect on 1-year all-cause mortality associated with hyperoxemia during AECOPD. Further studies are needed to prove/disprove our findings.

Effectiveness of a post-emergency department discharge multidisciplinary bundle in reducing acute hospital admissions for the elderly.

OBJECTIVE: We evaluated the effectiveness of the Subacute Ambulatory care for the Functionally challenged and Elderly (SAFE) programme, a post-emergency department (ED) discharge intervention for elderly and functionally challenged patients, in reducing acute hospital admissions. METHODS: This study was a 32-month retrospective quasi-experimental study comparing patients with at least one of six diagnostic classifications who underwent SAFE intervention with those who were eligible but declined and received usual ED care (control). The primary outcomes were rates of first acute hospital admission at 30 and 60 days post-ED discharge. Secondary outcomes were 20-day withdrawal rate and 60-day mortality. The difference in primary outcome between the two groups was compared using a Cox proportional hazards model. We reported adjusted hazard ratios (HRs) with their 95% confidence intervals (CIs) adjusting for predefined factors of age, sex, triage risk assessment tool scores and baseline ED utilization and acute hospital admission rates in the past year. RESULTS: There were 438 and 209 patients in the intervention and control groups, respectively. The intervention group had reduced risk of first acute hospital admission at 30 days (10 vs. 27%, HR=0.34, 95% CI: 0.22-0.52) and 60 days (18 vs. 33%, HR=0.48, 95% CI: 0.34-0.69) compared with the control. The 20-day withdrawal rate was 3.2%. Both groups did not differ in 60-day mortality rates. CONCLUSION: The SAFE programme was effective in reducing first acute hospital admissions in selected elderly and functionally challenged patients after ED discharge at 30 and 60 days compared with usual ED discharge care.

Traumatic diaphragmatic injuries: a retrospective review of a 12-year experience at a tertiary trauma centre.

INTRODUCTION: Traumatic diaphragmatic injuries (TDIs) are clinically challenging. We aimed to review TDIs treated at a tertiary trauma centre over a 12-year period. METHODS: This was a single-centre retrospective review of adult patients with TDIs treated between 1 January 2003 and 31 December 2014. Primary outcomes were mortality rates and Injury Severity Scores (ISS) associated with each TDI subtype. Secondary outcomes included proportions of TDIs diagnosed radiologically, operatively or during autopsy. We compared the TDI subtypes with respect to mechanism of injury, mortality rates and median ISS. Data was analysed using descriptive statistics. RESULTS: Among 46 patients studied, the TDI subtypes noted were acute diaphragmatic herniation (n = 14, 30.4%), tears (n = 22, 47.8%) and contusions (n = 10, 21.7%). Patients with these TDI subtypes had a mortality rate of 35.7%-100%, while the ISS ranges for survivors and deaths were 22.0-34.0 (interquartile range [IQR] 6.5-23.0) and 53.5-66.0 (IQR 16.0-28.5), respectively. TDIs were identified via chest radiography (n = 2/33, 6.1%) and computed tomography (n = 6/13, 46.2%). All survivors (n = 21) and deaths (n = 25) underwent open surgery or autopsy, respectively, which confirmed TDIs. Blunt traumas and penetrating traumas were more frequently associated with acute herniation/contusions and tears, respectively. There were statistically significant differences among the TDI subtypes in their mechanism of injury, mortality rate and median ISS of survivors. CONCLUSION: TDIs showed varying injury patterns with blunt versus penetrating mechanisms of injury, and were associated with significant mortality rates. Preoperative imaging had limited diagnostic use.

A randomised, double-blinded clinical study on the efficacy of multimedia presentation using an iPad for patient education of postoperative hip surgery patients in a public hospital in Singapore.

INTRODUCTION: This study compared patient satisfaction and recall of physiotherapy patient education among patients who had undergone hip surgery, with information presented via an iPad versus a standard paper booklet. METHODS: Patients who had undergone hip surgery joined and completed this single-centre study, which utilised a randomised parallel group design. They were randomly allocated to either Group A (received information on hip surgery physiotherapy via an iPad) or Group B (received the same information via a paper booklet). The participants were blinded to the intervention received by the other group and the testers were blinded to the intervention received by the participants. The interventions were carried out during the patients' first four postoperative physiotherapy sessions. The outcome measures were recorded using pre-validated questionnaires. RESULTS: A total of 42 participants (mean age 70 ± 12 years) were recruited. After the intervention, patients in both groups had improved recall of the information presented during patient education. However, the patients in Group A had a significantly better recall score than those in Group B (4.0 points higher, p < 0.001). The level of patient satisfaction was also significantly higher in Group A than in Group B (8.5 points higher, p < 0.001). CONCLUSION: While the use of an iPad and a paper booklet both had positive outcomes for patient recall and satisfaction, the use of an iPad was found to be more effective at improving patient satisfaction and recall of physiotherapy patient education in the present study.
