Lenvatinib Plus Pembrolizumab Versus Sunitinib in First-Line Treatment of Advanced Renal Cell Carcinoma: Final Prespecified Overall Survival Analysis of CLEAR, a Phase III Study.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We present the final prespecified overall survival (OS) analysis of the open-label, phase III CLEAR study in treatment-naïve patients with advanced renal cell carcinoma (aRCC). With an additional follow-up of 23 months from the primary analysis, we report results from the lenvatinib plus pembrolizumab versus sunitinib comparison of CLEAR. Treatment-naïve patients with aRCC were randomly assigned to receive lenvatinib (20 mg orally once daily in 21-day cycles) plus pembrolizumab (200 mg intravenously once every 3 weeks) or sunitinib (50 mg orally once daily [4 weeks on/2 weeks off]). At this data cutoff date (July 31, 2022), the OS hazard ratio (HR) was 0.79 (95% CI, 0.63 to 0.99). The median OS (95% CI) was 53.7 months (95% CI, 48.7 to not estimable [NE]) with lenvatinib plus pembrolizumab versus 54.3 months (95% CI, 40.9 to NE) with sunitinib; 36-month OS rates (95% CI) were 66.4% (95% CI, 61.1 to 71.2) and 60.2% (95% CI, 54.6 to 65.2), respectively. The median progression-free survival (95% CI) was 23.9 months (95% CI, 20.8 to 27.7) with lenvatinib plus pembrolizumab and 9.2 months (95% CI, 6.0 to 11.0) with sunitinib (HR, 0.47 [95% CI, 0.38 to 0.57]). Objective response rate also favored the combination over sunitinib (71.3% v 36.7%; relative risk 1.94 [95% CI, 1.67 to 2.26]). Treatment-emergent adverse events occurred in >90% of patients who received either treatment. In conclusion, lenvatinib plus pembrolizumab achieved consistent, durable benefit with a manageable safety profile in treatment-naïve patients with aRCC.

Review on the screening of urine glucose for early diagnosis of type 2 diabetes mellitus in school children and adolescents with obesity in Hong Kong.

OBJECTIVES: Obesity and type 2 diabetes mellitus (T2DM) are growing health concerns. Since 2005, Student Health Service (SHS) and Hong Kong Paediatric Society formulated a protocol on urine glucose screening (UGS) for early diagnosis of T2DM in students with obesity in Hong Kong. This study reviews students with T2DM captured by this screening program and compare the data with the Hong Kong Children Diabetes Registry (HKCDR) database, to see if the UGS program facilitates early diagnosis of T2DM. METHODS: Students between the ages of 10-18 years old with age- and sex-specific body mass index (BMI) >97th percentile who attended SHS between the school years from 2005/06 to 2017/18 were recruited for UGS. Those tested positive for random urine glucose underwent diagnostic testing for T2DM according to ADA guidelines. Demographic data and investigatory results from UGS and HKCDR within the same time period were compared. RESULTS: A total of 216,526 students completed UGS in the said period; 415 (0.19 %) students were tested positive for urine glucose of which 121 students were diagnosed with T2DM. UGS picked up 23 % of the newly diagnosed T2DM cases. When compared to the HKCDR database, students diagnosed via UGS were significantly younger, less obese, and had fewer diabetic related complications. The negative predictive value of UGS is high and can effectively rule out T2DM. CONCLUSIONS: Urine glucose screening is an inexpensive and simple test that allows for early diagnosis of T2DM among obese school students. Other methods including POCT HbA1c can be explored to improve program effectiveness.

Early Versus Late Feeding After Percutaneous Endoscopic Gastrostomy Placement in Trauma and Burn.

INTRODUCTION: Timing to resume feeds after percutaneous endoscopic gastrostomy (PEG) placement continues to vary among US trauma surgeons. The purpose of this study was to assess differences in meeting nutritional therapy goals and adverse outcomes with early versus late enteral feeding after PEG placement. METHODS: This retrospective review included 364 trauma and burn patients who underwent PEG placement. Data included patient characteristics, time to initiate feeds, rate feeds were resumed, % feed volume goals on postoperative days 0-7, and complications. Statistical analysis was performed comparing two groups (feeds ≤ 6 h versus > 6 h) and three subgroups (< 4 h, 4-6 h, ≥ 6 h) based on data quartiles. Chi-square/Fisher's exact test, independent-samples t-test, and one-way analysis of variance were used to analyze the data. RESULTS: Mean time to initiate feeds after PEG was 5.48 ± 4.79 h. Burn patients received early feeds in a larger proportion. A larger proportion of trauma patients received late feeds. The mean % of goal feed volume met on postoperative day 0 was higher in the early feeding group versus the late (P < 0.001). There were no differences in adverse events, even after subgroup analysis of those who received feeds < 4 h after PEG placement. CONCLUSIONS: Patients with early initiation of feeds after PEG placement achieve a higher percentage of goals on day 0 without an increased rate of adverse events. Unfortunately, patients routinely fall short of their target tube feeding goals.

Systemic treatment of advanced and metastatic urothelial cancer: The landscape in Australia.

The 5-year survival rate of metastatic urothelial carcinoma (mUC) is estimated to be as low as 5%. Currently, systemic platinum-based chemotherapy followed by avelumab maintenance therapy is the only first-line treatment for mUC that has an overall survival benefit. Cisplatin-based chemotherapy (usually in combination with gemcitabine) is the preferred treatment but carboplatin is substituted where contraindications to cisplatin exist. Treatment with immune checkpoint inhibitors, antibody-drug conjugates, and kinase inhibitors has not yet demonstrated superiority to chemotherapy as first-line therapy and remains investigational in this setting. A recent media release indicates that chemotherapy plus nivolumab gives an OS advantage as first-line treatment but results of this study have not yet been made public. Pembrolizumab remains an option in those having primary progression on first-line chemotherapy or within 12 months of neoadjuvant chemotherapy. The antibody-drug conjugate, enfortumab vedotin has TGA approval for patients whose cancer has progressed following chemotherapy and immunotherapy and has just received a positive Pharmaceutical Benefits Scheme recommendation. The use of molecular screens for somatic genetic mutations, gene amplifications, and protein expression is expanding as drugs that target such abnormalities show promise. However, despite these advances, a substantial proportion of patients with mUC have significant barriers to receiving any treatment, including advancing age, frailty, and comorbidities, and less toxic, effective therapies are needed.

Treatment patterns and outcomes in older adults with castration-resistant prostate cancer: Analysis of an Australian real-world cohort.

INTRODUCTION: Prostate cancer (PC) is the second commonest malignancy and fifth leading cause of cancer death in men worldwide. Older men are more likely to develop PC but are underrepresented in pivotal clinical trials, leading to challenges in treatment selection in the real-world setting. We aimed to examine treatment patterns and outcomes in older Australians with metastatic castration-resistant prostate cancer (mCRPC). MATERIALS AND METHODS: We identified 753 men with mCRPC within the electronic CRPC Australian Database (ePAD). Clinical data were analysed retrospectively to assess outcomes including time to treatment failure (TTF), overall survival (OS), PSA doubling time (PSADT), PSA50 response rate, and pre-defined adverse events of special interest (AESIs). Descriptive statistics were used to report baseline characteristics, stratified by age groups (<75y, 75-85y and >85y). Groups were compared using Kruskal-Wallis and Chi-square analyses. Time-to-event analyses were performed using Kaplan-Meier methods and compared through log-rank tests. Cox proportional hazards univariate and multivariate analyses were performed to evaluate the influence of variables on OS. RESULTS: Fifty-seven percent of men were aged <75y, 31% 75-85y, and 12% >85y. Patients ≥75y more frequently received only one line of systemic therapy (40% of <75y vs 66% 75-85y vs 68% >85y; P < 0.01). With increasing age, patients were more likely to receive androgen receptor signalling inhibitors (ARSIs) as initial therapy (42% of <75y vs 70% of 75-85y vs 84% of >85y; p < 0.01). PSA50 response rates or TTF did not significantly differ between age groups for chemotherapy or ARSIs. Patients >85y receiving enzalutamide had poorer OS but this was not an independent prognostic variable on multivariate analysis (hazard ratio [HR] 0.93(0.09-9.35); p = 0.95). PSADT >3 months was an independent positive prognostic factor for patients receiving any systemic therapy. Older patients who received docetaxel were more likely to experience AESIs (18% in <75y vs 37% 75-85y vs 33% >85y, p = 0.038) and to stop treatment as a result (21% in <75y vs 39% in 75-85y; p = 0.011). DISCUSSION: In our mCRPC cohort, older men received fewer lines of systemic therapy and were more likely to cease docetaxel due to adverse events. However, treatment outcomes were similar in most subgroups, highlighting the importance of individualised assessment regardless of age.

24 h Activity Guidelines in Children and Adolescents: A Prevalence Survey in Asia-Pacific Cities.

This study aimed to examine the prevalence of adherence to 24 h activity guidelines in children and adolescents from Asia-Pacific cities. In 1139 children aged 5-18 years, moderate-to-vigorous physical activity (MVPA), screen viewing time (SVT), sleep duration, child weight, height, sex, and age were parent-reported. Descriptive statistics were used to assess the number of guidelines met, and prevalence of adherence to activity guidelines by city and child sex. Prevalence of meeting all three 24 h activity guidelines was low across all countries (1.8-10.3%) (p < 0.05). Children from Thiruvananthapuram, India had the highest [10.3% (95% CI: 6.0-17.0)], while those from Tokyo, Japan had the lowest prevalence [1.8% (95% CI: 0.5-7.0)] of meeting all three guidelines. The highest prevalence of meeting individual MVPA, SVT and sleep guidelines was found in India [67.5% (95% CI: 58.8-75.1)], Kelaniya, Sri Lanka [63.2% (95% CI: 58.7-67.4)] and Kowloon, Hong Kong [59.4% (95% CI: 51.1-65.3)], respectively. Overall, a higher prevalence of boys met all three guidelines, compared to girls [5.9% (95% CI: 4.1-8.1) vs. 4.7% (3.1-6.6), p = 0.32]. The prevalence of adhering to all three activity guidelines was low in all five participating cities, with a higher proportion of boys meeting all guidelines.

Construction and characterization of a novel miniaturized filamentous phagemid for targeted mammalian gene transfer.

BACKGROUND: As simplistic proteinaceous carriers of genetic material, phages offer great potential as targeted vectors for mammalian transgene delivery. The filamentous phage M13 is a single-stranded DNA phage with attractive characteristics for gene delivery, including a theoretically unlimited DNA carrying capacity, amenability to tropism modification via phage display, and a well-characterized genome that is easy to genetically modify. The bacterial backbone in gene transfer plasmids consists of elements only necessary for amplification in prokaryotes, and, as such, are superfluous in the mammalian cell. These problematic elements include antibiotic resistance genes, which can disseminate antibiotic resistance, and CpG motifs, which are inflammatory in animals and can lead to transgene silencing. RESULTS: Here, we examined how M13-based phagemids could be improved for transgene delivery by removing the bacterial backbone. A transgene cassette was flanked by isolated initiation and termination elements from the phage origin of replication. Phage proteins provided in trans by a helper would replicate only the cassette, without any bacterial backbone. The rescue efficiency of "miniphagemids" from these split origins was equal to, if not greater than, isogenic "full phagemids" arising from intact origins. The type of cassette encoded by the miniphagemid as well as the choice of host strain constrained the efficiency of phagemid rescue. CONCLUSIONS: The use of two separated domains of the f1 ori improves upon a single wildtype origin while still resulting in high titres of miniphagemid gene transfer vectors. Highly pure lysates of miniaturized phagemids could be rapidly obtained in a straightforward procedure without additional downstream processing.

Patterns of Relapse in Australian Patients With Clinical Stage 1 Testicular Cancer: Utility of the Australian and New Zealand Urogenital and Prostate Cancer Trials Group Surveillance Recommendations.

PURPOSE: International guidelines advocate for active surveillance as the preferred treatment strategy for patients with stage 1 testicular cancer after orchidectomy although a personalized discussion is required. MATERIALS AND METHODS: We conducted an analysis of individuals registered in iTestis, Australia's testicular cancer registry, to describe the patterns of relapse and outcomes of patients treated in Australia where the Australian and New Zealand Urogenital and Prostate Cancer Trials Group Surveillance Recommendations are widely adopted. RESULTS: A total of 650 individuals diagnosed between 2000 and 2020 were included, 63% (411 of 650) seminoma and 37% (239 of 650) nonseminoma. The median age was 34 years (range 14-74). 26% (106 of 411) with seminoma and 15% (36 of 239) nonseminoma received adjuvant chemotherapy. After a median follow-up of 43 months (range 0-267) postorchidectomy, relapse occurred in 10% (43 of 411) of seminoma and 18% (43 of 239) of nonseminoma. The two-year relapse-free survival was 92% (95% CI, 89 to 95) and 82% (95% CI, 78 to 87) in seminoma and nonseminoma, respectively. All relapses (86 of 86) were detected at a routine surveillance visit; 98% (85 of 86) were asymptomatic and detected solely through imaging (62 of 86, 72%), tumor markers (6 of 86, 7%), or a combination (17 of 86, 20%). The most common relapse site was isolated retroperitoneal lymphadenopathy (53 of 86, 62%). No nonpulmonary visceral metastases occurred. At relapse, 98% (84 of 86) had International Germ Cell Cancer Collaborative Group (IGCCCG) good prognosis; 2 of 86 intermediate prognosis (both nonseminoma). No deaths occurred. CONCLUSION: In our cohort of stage 1 testicular cancer, where national surveillance recommendations have been widely adopted, recurrences were detected at routine surveillance visits and, almost exclusively, asymptomatic with IGCCCG good-prognosis disease. This provides reassurance that active surveillance is safe.

Survival by Depth of Response and Efficacy by International Metastatic Renal Cell Carcinoma Database Consortium Subgroup with Lenvatinib Plus Pembrolizumab Versus Sunitinib in Advanced Renal Cell Carcinoma: Analysis of the Phase 3 Randomized CLEAR Study.

BACKGROUND: The extent of tumor shrinkage has been deemed a predictor of survival for advanced/metastatic renal cell carcinoma (RCC), a disease with historically poor survival. OBJECTIVE: To perform an exploratory analysis of overall survival (OS) by tumor response by 6 mo, and to assess the efficacy and survival outcomes in specific subgroups. DESIGN, SETTING, AND PARTICIPANTS: CLEAR was an open-label, multicenter, randomized, phase 3 trial of first-line treatment of advanced clear cell RCC. INTERVENTION: Patients were randomized 1:1:1 to lenvatinib 20 mg orally daily with pembrolizumab 200 mg intravenously once every 3 wk, lenvatinib plus everolimus (not included in this analysis), or sunitinib 50 mg orally daily for 4 wk on treatment/2 wk of no treatment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Landmark analyses were conducted to assess the association of OS with tumor shrinkage and progressive disease status by 6 mo. Progression-free survival, duration of response, and objective response rate (ORR) were analyzed by the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk subgroup and by the presence of target kidney lesions. Efficacy was assessed by an independent review committee as per Response Evaluation Criteria in Solid Tumors version 1.1. RESULTS AND LIMITATIONS: Landmark analyses by tumor shrinkage showed that patients enrolled to lenvatinib plus pembrolizumab arm with a confirmed complete response or >75% target-lesion reduction by 6 mo had a 24-mo OS probability of ≥91.7%. A landmark analysis by disease progression showed that patients with no progression by 6 mo had lower probabilities of death in both arms. Patients with an IMDC risk classification of intermediate/poor had longer median progression-free survival (22.1 vs 5.9 mo) and a higher ORR (72.4% vs 28.8%) with lenvatinib plus pembrolizumab versus sunitinib. Similarly, results favored lenvatinib plus pembrolizumab in IMDC-favorable patients and those with/without target kidney lesions. Limitations of the study are that results were exploratory and not powered/stratified. CONCLUSIONS: Lenvatinib plus pembrolizumab showed improved efficacy versus sunitinib for patients with advanced RCC; landmark analyses showed that tumor response by 6 mo correlated with longer OS. PATIENT SUMMARY: In this report of the CLEAR trial, we explored the survival of patients with advanced renal cell carcinoma by assessing how well they initially responded to treatment. We also explored how certain groups of patients responded to treatment overall. Patients were assigned to cycles of either lenvatinib 20 mg daily plus pembrolizumab 200 mg every 3 wk or sunitinib 50 mg daily for 4 wk (followed by a 2-wk break). Patients who either had a "complete response" or had their tumors shrunk by >75% within 6 mo after starting treatment with lenvatinib plus pembrolizumab had better survival than those with less tumor reduction by 6 mo. Additionally, patients who had more severe disease (as per the International Metastatic Renal Cell Carcinoma Database Consortium) at the start of study treatment survived for longer without disease progression with lenvatinib plus pembrolizumab than with sunitinib.

Real-world clinical outcomes and cost estimates of metastatic castration-resistant prostate cancer treatment: does sequencing of taxanes and androgen receptor-targeted agents matter?

INTRODUCTION: Health economic outcomes of real-world treatment sequencing of androgen receptor-targeted agents (ARTA) and docetaxel (DOC) remain unclear. MATERIAL AND METHODS: Data from the electronic Castration-resistant Prostate cancer Australian Database (ePAD) were analyzed including median overall survival (mOS) and median time-to-treatment failure (mTTF). Mean total costs (mTC) and incremental cost-effectiveness ratios (ICER) of treatment sequences were estimated using the average sample method and Zhao and Tian estimator. RESULTS: Of 752 men, 441 received ARTA, 194 DOC, and 175 both sequentially. Of participants treated with both, first-line DOC followed by ARTA was the more common sequence (n = 125, 71%). mOS for first-line ARTA was 8.38 years (95% CI: 3.48, not-estimated) vs. 3.29 years (95% CI: 2.92, 4.02) for DOC. mTTF was 15.7 months (95% CI: 14.2, 23.7) for the ARTA-DOC sequence and 18.2 months (95% CI: 16.2, 23.2) for DOC-ARTA. In first-line, ARTA cost an additional $13,244 per mTTF month compared to DOC. In second-line, ARTA cost $6726 per mTTF month. The DOC-ARTA sequence saved $2139 per mTTF compared to ARTA-DOC, though not statistically significant. CONCLUSION: ICERs show ARTA had improved clinical benefit compared to DOC but at higher cost. There were no significant cost differences between combined sequences.

Diabetic ketoacidosis in children with new-onset type 1 diabetes mellitus: demographics, risk factors and outcome: an 11 year review in Hong Kong.

OBJECTIVES: Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes (T1D). The aim of this study is to analyze the incidence, clinical characteristics, management and outcome of children presenting with DKA in new-onset T1D from 2008 to 2018 in Hong Kong. METHODS: Data was extracted from the Hong Kong Childhood Diabetes Registry. All subjects less than 18 years with newly diagnosed T1D from 1 January 2008 to 31 December 2018 managed in the public hospitals were included. Information on demographics, laboratory parameters, DKA-related complications and management were analyzed. RESULTS: In the study period, there were 556 children with newly diagnosed T1D in our registry and 43.3% presented with DKA. The crude incidence rate of new-onset T1D with DKA was 1.79 per 100,000 persons/year (CI: 1.56-2.04). Subjects presenting with DKA were younger (9.5 ± 4.5 vs. 10.5 ± 4.4, p=0.01) and had shorter duration of symptoms (4.2 ± 5.9 days vs. 10.6 ± 17.1 days, p<0.01). Regarding management, up to 12.4% were given insulin boluses and 82.6% were started on insulin infusion 1 h after fluid resuscitation. The rate of cerebral edema was 0.8% and there was no mortality. CONCLUSIONS: Younger age and shorter duration of symptoms were associated with DKA in new-onset T1D. Despite availability of international guidelines, there was inconsistency in acute DKA management. These call for a need to raise public awareness on childhood diabetes as well as standardization of practice in management of pediatric DKA in Hong Kong.

Real-world first-line systemic therapy patterns in metastatic castration-resistant prostate cancer.

Introduction: Several systemic therapies have demonstrated a survival advantage in metastatic castration resistant prostate cancer (mCRPC). Access to these medications varies significantly worldwide. In Australia until recently, patients must have received docetaxel first, unless unsuitable for chemotherapy, despite no evidence suggesting superiority over androgen receptor signalling inhibitors (ARSIs). Our study investigated real-world systemic treatment patterns in Australian patients with mCRPC. Methods: The electronic CRPC Australian Database (ePAD) was interrogated to identify mCRPC patients. Clinicopathological features, treatment and outcome data, stratified by first-line systemic therapies, were extracted. Comparisons between groups utilised Kruskal-Wallis tests and Chi-Square analyses. Time-to-event data were calculated using Kaplan-Meier methods and groups compared using log-rank tests. Factors influencing overall survival (OS) and time to treatment failure (TTF) were analysed through Cox proportional hazards regression models. Results: We identified 578 patients who received first-line systemic therapy for mCRPC. Enzalutamide (ENZ) was most commonly prescribed (n = 240, 41%), followed by docetaxel (DOC, n = 164, 28%) and abiraterone (AA, n = 100, 17%). Patients receiving ENZ or AA were older (79, 78.5 years respectively) compared with DOC (71 years, p = 0.001) and less likely to have ECOG performance status 0 (45%, 44%, 59% in ENZ, AA and DOC groups respectively p < 0.0001). Median TTF was significantly higher in those receiving ENZ (12.4 months) and AA (11.9 months) compared to DOC (8.3 months, p < 0.001). PSA50 response rates and OS were not statistically different. Time to developing CRPC > 12 months was independently associated with longer TTF (HR 0.67, p < 0.001) and OS (HR 0.49, p = 0.002). Conclusion: In our real-world population, ENZ and AA were common first-line systemic therapy choices, particularly among older patients and those with poorer performance status. Patients receiving ENZ and AA demonstrated superior TTF compared to DOC, while OS was not statistically different. Our findings highlight the important role of ARSIs, given the variability of access worldwide.

Renoprotective effects of ferric citrate in a mouse model of chronic kidney disease.

In chronic kidney disease, ferric citrate has been shown to be an effective phosphate binder and source of enteral iron; however, the effects of ferric citrate on the kidney have been less well-studied. Here, in Col4α3 knockout mice-a murine model of progressive chronic kidney disease, we evaluated the effects of five weeks of 1% ferric citrate dietary supplementation. As expected, ferric citrate lowered serum phosphate concentrations and increased serum iron levels in the Col4α3 knockout mice. Consistent with decreased enteral phosphate absorption and possibly improved iron status, ferric citrate greatly reduced circulating fibroblast growth factor 23 levels. Interestingly, ferric citrate also lessened systemic inflammation, improved kidney function, reduced albuminuria, and decreased kidney inflammation and fibrosis, suggesting renoprotective effects of ferric citrate in the setting of chronic kidney disease. The factors mediating possible ferric citrate renoprotection, the mechanisms by which they may act, and whether ferric citrate affects chronic kidney disease progression in humans deserves further study.

Graduate medical education-led continuous assessment of burnout and learning environments to improve residents' wellbeing.

BACKGROUND: Promoting residents' wellbeing and decreasing burnout is a focus of Graduate Medical Education (GME). A supportive clinical learning environment is required to optimize residents' wellness and learning. OBJECTIVE: To determine if longitudinal assessments of burnout and learning environment as perceived by residents combined with applying continuous quality Model for Improvement and serial Plan, Do, Study, Act (PDSA) cycles to test interventions would improve residents' burnout. METHODS: From November 2017 to January 2020, 271 GME residents in internal medicine, general surgery, psychiatry, emergency medicine, family medicine and obstetrics and gynecology, were assessed over five cycles by Maslach Burnout Inventory (MBI), and by clinical learning environment factors (which included personal/social relationships, self-defined burnout, program burnout support, program back-up support, clinical supervision by faculty, and sleep difficulties). The results of the MBI and clinical learning environment factors were observed and analyzed to determine and develop indicated Institutional and individual program interventions using a Plan, Do, Study, Act process with each of the five cycles. RESULTS: The response rate was 78.34%. MBI parameters for all GME residents improved over time but were not statistically significant. Residents' positive perception of the clinical supervision by faculty was significantly and independently associated with improved MBI scores, while residents' self-defined burnout; and impaired personal relations perceptions were independently significantly associated with adverse MBI scores on liner regression. For all GME, significant improvements improved over time in residents' perception of impaired personal relationships (p < 0.001), self-defined burnout (p = 0.013), program burn-out support (p = 0.002) and program back-up support (p = 0.028). For the Internal Medicine Residency program, there were statistically significant improvements in all three MBI factors (p < 0.001) and in clinical learning environment measures (p = 0.006 to < 0.001). Interventions introduced during the PDSA cycles included organization-directed interventions (such as: faculty and administrative leadership recruitment, workflow interventions and residents' schedule optimization), and individual interventions (such as: selfcare, mentoring and resilience training). CONCLUSION: In our study, for all GME residents, clinical learning environment factors in contrast to MBI factors showed significant improvements. Residents' positive perception of the clinical learning environment was associated with improved burnout measures. Residents in separate programs responded differently with one program reaching significance in all MBI and clinical learning environment factors measured. Continuous wellbeing assessment of all GME residents and introduction of Institutional and individual program interventions was accomplished.

Pretreatment of choriocarcinoma syndrome: a rare complication of metastatic germ cell tumours.

A 27-year-old man newly diagnosed with metastatic testicular choriocarcinoma developed a large right perinephric haematoma secondary to a metastatic deposit in his right kidney. His presentation was also complicated by bilateral iliac venous thrombosis and pulmonary embolism identified prior to initiation of chemotherapy. He underwent multiple attempts at angioembolisation of the bleeding vessels and ultimately angioembolisation of the main renal artery had to be performed to control the bleeding. Following resolution and commencement of chemotherapy, the patient also developed spontaneous intracranial haemorrhage requiring craniotomy.

Beyond cabazitaxel: Late line treatments in metastatic castration resistant prostate cancer: A retrospective multicentre analysis.

AIMS: Multiple life-prolonging therapies are available for metastatic castration-resistant prostate cancer (mCRPC). However, the optimal treatment strategy following progression through standard treatment with docetaxel, androgen receptor signaling inhibitor (ARSI) and cabazitaxel, remains unclear. We aimed to describe treatment patterns in men with mCRPC following progression on standard treatments and determine whether subsequent treatment choice impacts overall survival. METHODS: Clinicopathologic and treatment data were extracted from the electronic CRPC Australian Database (ePAD) for patients who had received docetaxel, ARSIs and cabazitaxel in any order. Data were analyzed to compare groups that did versus did not receive subsequent systemic therapy. Treatment sequences, median duration of treatment, and median overall survival (mOS) were reported for each treatment group. RESULTS: Ninety-eight eligible patients were identified, with 51 receiving subsequent systemic therapy. Those who received further treatment were younger (68 vs. 71 years, p < .01) but did not have any other differences in clinicopathologic features compared to those who received no further treatment. Patients who received upfront docetaxel were more likely to proceed to subsequent treatment (p = .02). Subsequent systemic therapies varied, the most common being carboplatin-based regimens (n = 13, 25.5%) and many patients were rechallenged with ARSI (n = 10, 19.6%) or docetaxel (n = 6, 11.8%). There was no difference in mOS according to subsequent systemic therapy (p = .09). CONCLUSION: This retrospective multicenter analysis demonstrates the variation in treatment sequences used for mCRPC in the real-world setting. In the absence of high quality, prospective evidence, our results suggest that subsequent treatment choice does not influence survival outcomes and the optimal choice is guided by individual patient and disease-related factors.

Is the search for cerebral palsy 'cures' a reasonable and appropriate goal in the 2020s?

In the field of disability research and advocacy, the notion of 'cures' is contentious. Cerebral palsy (CP) is no exception. In this narrative review, we combine perspectives gained during community consultation undertaken for the Australian and New Zealand Cerebral Palsy Strategy, 2020 with those published in the scientific and grey literature to understand whether 'cures for CP' is a reasonable and appropriate goal. We frame these perspectives through the lens of several ethical principles central to the discussion. These include maintaining hope while also being realistic, sensitivity to sharply different viewpoints amongst people with disability and their families, and responding to community priorities, societal attitudes, and identity. Through this exploration of the literature and perspectives, we arrived at a definition of 'cures for CP' that is pluralized and focuses on functional improvement and/or symptom reduction whilst still acknowledging the potential for neural repair/regeneration strategies.

Incidence and clinical characteristics of pediatric-onset type 2 diabetes in Hong Kong: The Hong Kong childhood diabetes registry 2008 to 2017.

OBJECTIVE: With increasing prevalence of childhood obesity worldwide, the incidence of pediatric-onset type 2 diabetes (T2D) is also increasing in many countries. We aim to analyze the time trend and incidence of T2D in children in Hong Kong from 2008 to 2017, and to characterize clinical characteristics at diagnosis. METHODS: Data were retrieved from the Hong Kong Childhood Diabetes Registry. All children with T2D diagnosed at the age of less than 18 years from January 1, 2008 to December 31, 2017 and managed in the public health care system were included in this study. RESULTS: In the incident years of 2008-2017 period, 391 children were diagnosed with T2D. The crude incidence rate was 3.42 per 100,000 persons/year [95% confidence interval (CI) 3.08-3.76], which was much higher than that in last registry of 1.27 per 100,000 persons/year in 1997-2007 (P < 0.001).Most children (76%) were asymptomatic and were diagnosed by routine screening. At presentation, a significant proportion presented with co-morbidities including fatty liver (37.9%), dyslipidaemia (35.3%), hypertension (22.5%), and microalbuminuria (12.8%). CONCLUSIONS: The incidence of T2D in children has increased significantly in Hong Kong. Most of them were asymptomatic and picked up on routine health screening. Yet, comorbidities were commonly identified at diagnosis.

Predictors of real-world utilisation of docetaxel combined with androgen deprivation therapy in metastatic hormone-sensitive prostate cancer.

BACKGROUND: Docetaxel has emerged as a standard-of-care for metastatic hormone-sensitive prostate cancer (mHSPC). Uptake of docetaxel for mHSPC in Australia has not previously been reported. AIMS: To investigate the real-world uptake of docetaxel in mHSPC and to identify predictors of utilisation of docetaxel in mHSPC. METHODS: Men diagnosed from June 2014 to December 2018 and enrolled in the Prostate Cancer Outcomes Registry-Victoria (PCOR-Vic) were included. Data collected include demographics, diagnosis method and institution, staging investigations and treatments within 12 months of diagnosis. Wilcoxon rank-sum, Chi-squared and trend tests were used to identify predictors of docetaxel utilisation. All predictors were entered as covariates simultaneously into a multivariable logistic regression model. Statistical significance was set at 0.05 (two sided). RESULTS: In all, 1014 men with mHSPC were analysed, 25% of whom received docetaxel with androgen deprivation therapy. Uptake of docetaxel increased from 20% in 2014 to 33% in 2018. Predictors of higher usage of docetaxel were younger age and treatment in a private hospital, with both remaining significant on multivariable analysis. Notably, the proportion of men aged <70 years receiving docetaxel increased from 54% in 2014-2015 to 64% in 2016-2018, while in men aged ≥70 years the comparative figures were 15% and 22% respectively. CONCLUSIONS: Although docetaxel was not used in the majority of cases, there was a clear increase in docetaxel uptake, especially in younger men following publication of the CHAARTED and STAMPEDE trials. Identifying barriers to real-world implementation of pivotal clinical trial data is critical to improving outcomes in mHSPC.
