A Phase 2 Study of Sitravatinib in Combination with Nivolumab in Patients with Advanced or Metastatic Urothelial Carcinoma. Eur Urol Oncol 2023:S2588-9311(23)00282-1. [PMID: 38105142 DOI: 10.1016/j.euo.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/16/2023] [Accepted: 12/01/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND AND OBJECTIVE Checkpoint inhibitor therapy (CPI) has demonstrated survival benefits in urothelial carcinoma (UC); however, not all patients benefit from CPI due to resistance. Combining sitravatinib, a multitargeted receptor tyrosine kinase inhibitor of TYRO3, AXL, and MERTK (TAM) receptors and VEGFR2, with CPI may improve antitumor responses. Our objective was to assess the efficacy and safety of sitravatinib plus nivolumab in patients with advanced/metastatic UC. METHODS The 516-003 trial (NCT03606174) is an open-label, multicohort phase 2 study evaluating sitravatinib plus nivolumab in patients with advanced/metastatic UC enrolled in eight cohorts depending on prior treatment with CPI, platinum-based chemotherapy (PBC), or antibody-drug conjugate (ADC). Overall, 244 patients were enrolled and treated with sitravatinib plus nivolumab (median follow-up 14.1-38.2 mo). Sitravatinib (free-base capsules 120 mg once daily [QD] or malate capsule 100 mg QD) plus nivolumab (240 mg every 2 wk/480 mg every 4 wk intravenously). KEY FINDINGS AND LIMITATIONS The primary endpoint was objective response rate (ORR; RECIST v1.1). The secondary endpoints included progression-free survival (PFS) and safety. The Predictive probability design and confidence interval methods were used. Among patients previously treated with PBC, ORR, and median PFS were 32.1% and 3.9 mo in CPI-naïve patients (n = 53), 14.9% and 3.9 mo in CPI-refractory patients (n = 67), and 5.4% and 3.7 mo in CPI- and ADC-refractory patients (n = 56), respectively. Across all cohorts, grade 3 treatment-related adverse events (TRAEs) occurred in 51.2% patients and grade 4 in 3.3%, with one treatment-related death (cardiac failure). Immune-related adverse events occurred in 50.4% patients. TRAEs led to sitravatinib/nivolumab discontinuation in 6.1% patients. CONCLUSIONS AND CLINICAL IMPLICATIONS Sitravatinib plus nivolumab demonstrated a manageable safety profile but did not result in clinically meaningful ORRs in patients with advanced/metastatic UC in the eight cohorts studied. PATIENT SUMMARY In this study, the combination of two anticancer drugs, sitravatinib and nivolumab, resulted in manageable side effects but no meaningful responses in patients with bladder cancer.

Abstract
PURPOSE To provide guidance to clinicians regarding the use of systemic therapy for melanoma. METHODS American Society of Clinical Oncology convened an Expert Panel and conducted an updated systematic review of the literature. RESULTS The updated review identified 21 additional randomized trials. UPDATED RECOMMENDATIONS Neoadjuvant pembrolizumab was newly recommended for patients with resectable stage IIIB to IV cutaneous melanoma. For patients with resected cutaneous melanoma, adjuvant nivolumab or pembrolizumab was newly recommended for stage IIB-C disease and adjuvant nivolumab plus ipilimumab was added as a potential option for stage IV disease. For patients with unresectable or metastatic cutaneous melanoma, nivolumab plus relatlimab was added as a potential option regardless of BRAF mutation status and nivolumab plus ipilimumab followed by nivolumab was preferred over BRAF/MEK inhibitor therapy. Talimogene laherparepvec is no longer recommended as an option for patients with BRAF wild-type disease who have progressed on anti-PD-1 therapy. Ipilimumab- and ipilimumab-containing regimens are no longer recommended for patients with BRAF-mutated disease after progression on other therapies.This full update incorporates the new recommendations for uveal melanoma published in the 2022 Rapid Recommendation Update.Additional information is available at www.asco.org/melanoma-guidelines.

Efficacy and Safety of Telaglenastat Plus Cabozantinib vs Placebo Plus Cabozantinib in Patients With Advanced Renal Cell Carcinoma: The CANTATA Randomized Clinical Trial. JAMA Oncol 2022; 8:1411-1418. [PMID: 36048457 PMCID: PMC9437824 DOI: 10.1001/jamaoncol.2022.3511] [Citation(s) in RCA: 35] [Impact Index Per Article: 17.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 06/16/2022] [Indexed: 11/14/2022]
Abstract
Importance Dysregulated metabolism is a hallmark of renal cell carcinoma (RCC). Glutaminase is a key enzyme that fuels tumor growth by converting glutamine to glutamate. Telaglenastat is an investigational, first-in-class, selective, oral glutaminase inhibitor that blocks glutamine utilization and downstream pathways. Preclinically, telaglenastat synergized with cabozantinib, a VEGFR2/MET/AXL inhibitor, in RCC models. Objective To compare the efficacy and safety of telaglenastat plus cabozantinib (Tela + Cabo) vs placebo plus cabozantinib (Pbo + Cabo). Design, Setting, and Participants CANTATA was a randomized, placebo-controlled, double-blind, pivotal trial conducted at sites in the US, Europe, Australia, and New Zealand. Eligible patients had metastatic clear-cell RCC following progression on 1 to 2 prior lines of therapy, including 1 or more antiangiogenic therapies or nivolumab plus ipilimumab. The data cutoff date was August 31, 2020. Data analysis was performed from December 2020 to February 2021. Interventions Patients were randomized 1:1 to receive oral cabozantinib (60 mg daily) with either telaglenastat (800 mg twice daily) or placebo until disease progression or unacceptable toxicity. Main Outcomes and Measures The primary end point was progression-free survival (Response Evaluation Criteria in Solid Tumors version 1.1) assessed by blinded independent radiology review. Results A total of 444 patients were randomized: 221 to Tela + Cabo (median [range] age, 61 [21-81] years; 47 [21%] women and 174 [79%] men) and 223 to Pbo + Cabo (median [range] age, 62 [29-83] years; 68 [30%] women and 155 [70%] men). A total of 276 (62%) patients had received prior immune checkpoint inhibitors, including 128 with prior nivolumab plus ipilimumab, 93 of whom had not received prior antiangiogenic therapy. Median progression-free survival was 9.2 months for Tela + Cabo vs 9.3 months for Pbo + Cabo (HR, 0.94; 95% CI, 0.74-1.21; P = .65). Overall response rates were 31% (69 of 221) with Tela + Cabo vs 28% (62 of 223) with Pbo + Cabo. Treatment-emergent adverse event (TEAE) rates were similar between arms. Grade 3 to 4 TEAEs occurred in 160 patients (71%) with Tela + Cabo and 172 patients (79%) with Pbo + Cabo and included hypertension (38 patients [17%] vs 40 patients [18%]) and diarrhea (34 patients [15%] vs 29 patients [13%]). Cabozantinib was discontinued due to AEs in 23 patients (10%) receiving Tela + Cabo and 33 patients (15%) receiving Pbo + Cabo. Conclusions and Relevance In this randomized clinical trial, telaglenastat did not improve the efficacy of cabozantinib in metastatic RCC. Tela + Cabo was well tolerated with AEs consistent with the known risks of both agents. Trial Registration ClinicalTrials.gov Identifier: NCT03428217.

Cambridge hybrid closed-loop algorithm in children and adolescents with type 1 diabetes: a multicentre 6-month randomised controlled trial. Lancet Digit Health 2022; 4:e245-e255. [PMID: 35272971 DOI: 10.1016/s2589-7500(22)00020-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 12/10/2021] [Accepted: 01/25/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Closed-loop insulin delivery systems have the potential to address suboptimal glucose control in children and adolescents with type 1 diabetes. We compared safety and efficacy of the Cambridge hybrid closed-loop algorithm with usual care over 6 months in this population. METHODS In a multicentre, multinational, parallel randomised controlled trial, participants aged 6-18 years using insulin pump therapy were recruited at seven UK and five US paediatric diabetes centres. Key inclusion criteria were diagnosis of type 1 diabetes for at least 12 months, insulin pump therapy for at least 3 months, and screening HbA1c levels between 53 and 86 mmol/mol (7·0-10·0%). Using block randomisation and central randomisation software, we randomly assigned participants to either closed-loop insulin delivery (closed-loop group) or to usual care with insulin pump therapy (control group) for 6 months. Randomisation was stratified at each centre by local baseline HbA1c. The Cambridge closed-loop algorithm running on a smartphone was used with either (1) a modified Medtronic 640G pump, Medtronic Guardian 3 sensor, and Medtronic prototype phone enclosure (FlorenceM configuration), or (2) a Sooil Dana RS pump and Dexcom G6 sensor (CamAPS FX configuration). The primary endpoint was change in HbA1c at 6 months combining data from both configurations. The primary analysis was done in all randomised patients (intention to treat). Trial registration ClinicalTrials.gov, NCT02925299. FINDINGS Of 147 people initially screened, 133 participants (mean age 13·0 years [SD 2·8]; 57% female, 43% male) were randomly assigned to either the closed-loop group (n=65) or the control group (n=68). Mean baseline HbA1c was 8·2% (SD 0·7) in the closed-loop group and 8·3% (0·7) in the control group. At 6 months, HbA1c was lower in the closed-loop group than in the control group (between-group difference -3·5 mmol/mol (95% CI -6·5 to -0·5 [-0·32 percentage points, -0·59 to -0·04]; p=0·023). Closed-loop usage was low with FlorenceM due to failing phone enclosures (median 40% [IQR 26-53]), but consistently high with CamAPS FX (93% [88-96]), impacting efficacy. A total of 155 adverse events occurred after randomisation (67 in the closed-loop group, 88 in the control group), including seven severe hypoglycaemia events (four in the closed-loop group, three in the control group), two diabetic ketoacidosis events (both in the closed-loop group), and two non-treatment-related serious adverse events. There were 23 reportable hyperglycaemia events (11 in the closed-loop group, 12 in the control group), which did not meet criteria for diabetic ketoacidosis. INTERPRETATION The Cambridge hybrid closed-loop algorithm had an acceptable safety profile, and improved glycaemic control in children and adolescents with type 1 diabetes. To ensure optimal efficacy of the closed-loop system, usage needs to be consistently high, as demonstrated with CamAPS FX. FUNDING National Institute of Diabetes and Digestive and Kidney Diseases.

Abstract
Purpose The aim of this study is to report the characteristic and mortality outcomes of lung transplant patients that contracted COVID19. Methods A retrospective chart review was conducted of lung transplant recipients who tested positive for COVID19 from 6/1/2020 to 9/1/2021. Results Forty-five patients were included for mortality incidence review with 2 patients who were admitted to outside facilities during their COVID diagnosis with limited treatment data. Mortality incidence was 15.5% with cohort mean age of 62 (±11.7). Median time from transplant to infection was 1281 days (223-5800). Five patients required O2 and n=5 were intubated with 80% mortality (n=4) among those intubated. Baseline demographics of age, gender, indication for transplant or race were not statistically different among patients that died vs those that survived. Vaccinations (2 doses) prior to infection were evident in n=35 (77.8%) of the patients. Maintenance immunosuppressants and covid therapies (table 1) did not have an associated difference in survival from infection. A significant association with mortality was found from the time of reported symptoms to triage or hospitalization in those that survived vs died, 3.3 vs 9.4 days (p=0.003). Conclusion This is one of the largest cohorts reporting lung transplant recipients who contracted COVID19, and despite lungs being the organ directly affected by COVID19, mortality rates are comparable to rates reported in other solid organ transplants. Time to triage from symptom onset to clinic management or hospital admission for COVID appears to be associated with improved mortality rates.

P–222 Can we optimise the time that we perform the fertilisation check in the lab? Lessons learnt from time-lapse incubation. Hum Reprod 2021.

Abstract
Abstract
Study question
Can time-lapse data be used to identify the optimum time to perform the fertilisation check for oocytes cultured in standard incubation?
Summary answer
The optimum time to perform fertilisation checks for oocytes cultured in standard incubation is 16.5hpi+/–0.5h.
What is known already
Time-lapse incubation allows the embryologist to retrospectively review collated images of oocytes and embryos to capture important embryological observations that may have otherwise been missed. This is a luxury not available to embryologists when oocytes or embryos are cultured in standard incubation. Traditionally, the optimum time to perform the fertilisation check is 17 hours post insemination (hpi) +/- 1 hour. It was hypothesised that this could be fine-tuned ensuring the maximum number of fertilised oocytes were observed, thereby increasing the number of usable embryos for the patient.
Study design, size, duration
This was a retrospective, multicentre analysis including data from 27,022 ICSI derived embryos cultured in time-lapse incubation between January 2011 to November 2019.
Participants/materials, setting, methods
The time of pronuclei appearance and disappearance was recorded using the time-lapse incubation software. The number of oocytes exhibiting normal fertilisation (defined as the presence of two pronuclei) during 30 minute intervals from 15hpi to 20hpi was determined.
Main results and the role of chance
Between 15–17.5hpi the average number of oocytes exhibiting normal fertilisation was 98.19% with most oocytes having visible pronuclei at 16–16.5hpi (98.32%). At 18–18.5hpi the number of visible pronuclei falls to 95.53% and continues to fall to 87.02% at 19.5–20hpi meaning that over 3000 (11%) normally fertilised oocytes, within this cohort, would not be identified.
Limitations, reasons for caution
The conclusions of this investigation cannot be effectively extrapolated to IVF embryos as only ICSI embryos were used for the determination of the results.
Wider implications of the findings: The optimum time to perform fertilisation checks for oocytes cultured in standard incubation is 16.5hpi+/–0.5h. However, without the use of time-lapse incubation, the fertilisation of at least 2% of embryos that create a fetal heart will be missed, even if the fertilisation check is performed in the optimum window (16.5hpi+/–0.5h).

P–792 The introduction of an embryo morphokinetics annotation quality assurance scheme across ten fertility clinics including 59 participants. Hum Reprod 2021.

Abstract
Abstract
Study question
Can a group-wide quality assurance scheme be developed to effectively determine inter-operator agreement for morphokinetic parameters of interest.
Summary answer
Very strong agreement was found between all operators except for one, therefore this scheme effectively identified areas of improvement in inter-operator annotations.
What is known already
Where fertility clinics use embryo morphokinetics to determine viability potential, quality assurance of annotations is essential. Embryo selection algorithms rely on the manual determination of certain morphokinetic parameters. Variations in these parameters can lead to differences in the algorithm score attributed to an embryo thus potentially affecting its fate. It is vital that all embryologists involved in embryo annotation and selection are consistent with their annotation approach through regular quality assurance mechanisms.
Study design, size, duration
Each participant was required to annotate the same three embryos for morphokinetic parameters of interest, including tPB2, tPNf, t2 to t5, t8, tM, tSB, tB. Participants were also required to grade embryos at 68 hours post insemination (hpi), 112hpi and to assess additional parameters used for embryo selection or future investigations, such as the extent of morula compaction. The aim of this scheme is to release new distribution each quarter to ensure regular participation.
Participants/materials, setting, methods
All embryologists responsible for embryo annotation in a single, UK fertility group were enrolled onto the scheme. A total of 59 participants from 10 fertility clinics in the UK were included. Inter-operator agreement was assessed using two-way, mixed intraclass correlation coefficient (ICC) for consistency. Five categories of agreement were determined based on ICC score; very weak (0–0.2), weak (0.21–0.4), moderate (0.41–0.6), strong (0.61–0.8) and very strong (0.81–1.0).
Main results and the role of chance
Very strong agreement (0.81–1.0) was observed between all operators for all parameters assessed except for one operator who showed a weak agreement (0.21–0.4) with all other operators. Descriptive statistics revealed standard deviations (SD) ranging from 0.34 (t3) to 3.43 (t5). For each parameter the SD across the three assessed embryos ranged from 0.34–3.43; tPB2 (0.11–0.98), tPNf (2.06–4.40), t2 (0.22–0.80), t3 (0.16–0.70), t4 (0.39–0.65). t5 (2.40–5.44), t8 (0.33–2.72), tM (1.00–2.72), tSB (1.08–2.67), tB (1.12–1.81). These results indicate a high concordance with less subjective annotations such as the cell stage divisions and more variability with the subjective annotations such as the blastulation parameters. The concordance with less well practiced or understood annotations, such as extent of morula compaction, planar or tetrahedral orientation at the four cell stage as well as angle of extrusion of second polar body in relation to the first polar body, was poorer as indicated using descriptive statistics. This highlighted the need for experience in performing these annotations before drawing conclusions regarding their predictive nature in relation to an embryo’s viability.
Limitations, reasons for caution
The variability between more subjective parameters would be expected to be higher than others. The participation in these schemes can create false environments which do not reflect how an embryologist would usually score; they may spend longer on some decisions given the nature of the scheme.
Wider implications of the findings: Quality assurance of morphokinetic annotations across clinics utilising standardised selection models is crucial. Robust annotation policies and education programmes are essential in achieving consistent results between operators. Quality assurance schemes can identify individuals who lack consistency overall and can identify reliably annotated parameters to inform inclusion in embryo selection algorithms.

Abstract
Abstract
Background
The aim of this study is to systematically compare rates of erosion and chronic pain after mesh insertion for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) surgery.
Method
A systematic electronic search was performed on studies that evaluated the incidence of erosion and chronic pain after mesh insertion for POP or SUI. The primary outcome measurement was to compare mesh erosion and chronic pain rates for POP and SUI surgery.
Results
Twenty-six studies on 292,606 patients (n = 9077 for POP surgery and n = 283529 for SUI surgery) met inclusion criteria. The POP group were older (p < 0.0001) and had a lower BMI (p < 0.0001). Mesh erosion rates were significantly greater in the POP group compared to the SUI group (4% versus 1.9%) [OR 2.13; 95% CI 1.91-2.37; p < 0.0001]. The incidence of chronic pain was significantly greater in the POP group compared to the SUI group (6.7% versus 0.6%) [OR 11.02; 95% CI 8.15-14.9; p < 0.0001].
Conclusions
The risk of mesh erosion and chronic pain is significantly higher after surgery for POP compared to SUI. Since a higher volume of mesh is typically used for POP surgery this supports evidence for a dose-response relationship between the volume of mesh used and the erosion risk.

Abstract
PURPOSE To provide guidance to clinicians regarding the use of systemic therapy for melanoma. METHODS ASCO convened an Expert Panel and conducted a systematic review of the literature. RESULTS A systematic review, one meta-analysis, and 34 additional randomized trials were identified. The published studies included a wide range of systemic therapies in cutaneous and noncutaneous melanoma. RECOMMENDATIONS In the adjuvant setting, nivolumab or pembrolizumab should be offered to patients with resected stage IIIA/B/C/D BRAF wild-type cutaneous melanoma, while either of those two agents or the combination of dabrafenib and trametinib should be offered in BRAF-mutant disease. No recommendation could be made for or against the use of neoadjuvant therapy in cutaneous melanoma. In the unresectable/metastatic setting, ipilimumab plus nivolumab, nivolumab alone, or pembrolizumab alone should be offered to patients with BRAF wild-type cutaneous melanoma, while those three regimens or combination BRAF/MEK inhibitor therapy with dabrafenib/trametinib, encorafenib/binimetinib, or vemurafenib/cobimetinib should be offered in BRAF-mutant disease. Patients with mucosal melanoma may be offered the same therapies recommended for cutaneous melanoma. No recommendation could be made for or against specific therapy for uveal melanoma.

Abstract
PURPOSE Platinum-based chemotherapy for first-line treatment of metastatic urothelial cancer is typically administered for a fixed duration followed by observation until progression. "Switch maintenance" therapy with PD-1 blockade at the time of chemotherapy cessation may be attractive for mechanistic and pragmatic reasons. PATIENTS AND METHODS Patients with metastatic urothelial cancer achieving at least stable disease on first-line platinum-based chemotherapy were enrolled. Patients were randomly assigned double-blind 1:1 to switch maintenance pembrolizumab 200 mg intravenously once every 3 weeks versus placebo for up to 24 months. Patients with disease progression on placebo could cross over to pembrolizumab. The primary objective was to determine the progression-free survival. Secondary objectives included determining overall survival as well as treatment outcomes according to PD-L1 combined positive score (CPS). RESULTS Between December 2015 and November 2018, 108 patients were randomly assigned to pembrolizumab (n = 55) or placebo (n = 53). The objective response rate was 23% with pembrolizumab and 10% with placebo. Treatment-emergent grade 3-4 adverse events occurred in 59% receiving pembrolizumab and 38% of patients receiving placebo. Progression-free survival was significantly longer with maintenance pembrolizumab versus placebo (5.4 months [95% CI, 3.1 to 7.3 months] v 3.0 months [95% CI; 2.7 to 5.5 months]; hazard ratio, 0.65; log-rank P = .04; maximum efficiency robust test P = .039). Median overall survival was 22 months (95% CI, 12.9 months to not reached) with pembrolizumab and 18.7 months (95% CI, 11.4 months to not reached) with placebo. There was no significant interaction between PD-L1 CPS ≥ 10 and treatment arm for progression-free survival or overall survival. CONCLUSION Switch maintenance pembrolizumab leads to additional objective responses in patients achieving at least stable disease with first-line platinum-based chemotherapy and prolongs progression-free survival in patients with metastatic urothelial cancer.

Abstract
INTRODUCTION The initial treatment for many orthopaedic injuries is splinting. Unfortunately, formal musculoskeletal training is limited in primary care leading to deficiencies in competency and confidence. Suboptimal splints can result in complications such as skin break-down, worsening of deformity, and increased pain. Our orthopaedic surgery clinic often cares for patients who initially present to an emergency department or primary care clinic for their orthopaedic injury. Previous studies have shown that a high number of splints are applied improperly in the primary care setting, which could result in in avoidable skin complications and fracture instability. METHODS Orthopaedic surgery residents held a splinting workshop for family medicine residents. The workshop involved didactic and skills portions. Pre- and post-surveys were administered using a 10-point scale to assess confidence in applying three common splints. The data were analyzed using student's t-test and qualitative feed-back. RESULTS Confidence in applying and molding each splint type improved significantly (p < 0.05). Knowledge in splint construction improved significantly as well (p < 0.05). Subjective feedback was positive. CONCLUSION These results showed inter-residency education can increase residents' confidence in skill-based medical care significantly. The results are encouraging and should facilitate further collaboration between multispecialty residency programs to improve patient care. Further investigation is needed to determine how well skills gained in workshop are retained.

Modified frailty index predicts early outcomes after colorectal surgery: an ACS-NSQIP study. Colorectal Dis 2019; 21:1192-1205. [PMID: 31162882 DOI: 10.1111/codi.14725] [Citation(s) in RCA: 66] [Impact Index Per Article: 13.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Accepted: 05/14/2019] [Indexed: 02/08/2023]
Abstract
AIM Frailty is defined as a decrease in physiological reserve with increased risk of morbidity following significant physiological stressors. This study examines the predictive power of the five-item modified frailty index (5-mFI) in predicting outcomes in colorectal surgery patients. METHODS The American College of Surgeons National Surgical Quality Improvement Program Database was queried from 2011 to 2016 to determine the predictive power of 5-mFI in patients who had colorectal surgery. RESULTS Of 295 490 patients, 45.8% had a score of 0, 36.2% had a score of 1 and 18% had a score of ≥ 2. On univariate analysis, frailer patients had significantly greater incidences for overall morbidity, serious morbidity, mortality, prolonged length of hospital stay, discharge to a facility other than home, reoperation and unplanned readmission. These findings were consistent on multivariate analysis where the frailest patients had greater odds of postoperative overall morbidity (OR 1.39; 95% CI 1.35-1.43), serious morbidity (OR 1.39; 95% CI 1.33-1.45), mortality (OR 2.00; 95% CI 1.87-2.14), prolonged length of hospital stay (OR 1.24; 95% CI 1.20-1.27), discharge destination to a facility other than home (OR 2.80; 95% CI 2.70-2.90), reoperation (OR 1.17; 95% CI 1.11-1.23) and unplanned readmission (OR 1.31; 95% CI 1.26-1.36). Weighted kappa statistics showed strong agreement between the 5-mFI and 11-mFI (kappa = 0.987, P < 0.001). CONCLUSIONS The 5-mFI is a valid and easy to use predictor of 30-day postoperative outcomes after colorectal surgery. This tool may guide the surgeon to proactively recognize frail patients to instigate interventions to optimize them preoperatively.

Abstract
BACKGROUND AND OBJECTIVES The American Board of Family Medicine (ABFM) is the first medical specialty board to require all residents participate in the maintenance of certification (MOC) process prior to sitting for board certification. This study used surveys and focus groups of family medicine residents in four university-affiliated residency programs to explore participants' perceived benefits and barriers to common methods of completing the performance improvement in practice (Part IV) MOC requirement, and the perceived impact on practice. METHODS Residents independently selected into one of three ABFM-approved methods of meeting the Part IV requirement. Following completion of the activity, participants completed a survey and then participated in a focus group. RESULTS Residents cited time constraints as a major barrier to all Part IV methods. They also reported lack of relevance to practice, deficiencies in performance improvement skills, and access to clinical data. Ease of use was a benefit of online modules, but residents did not perceive them as relevant to practice or leading practice change. Portfolio and self-directed activities were perceived as most relevant to practice and improved patient care, and involved more team-based experiences. Most participants would not participate in Part IV if not required. CONCLUSIONS Group quality improvement projects through the portfolio-approved and self-directed activities seemed to be the most positively reported way to complete the ABFM requirement. Regardless of method, time constraints and quality improvement expertise are significant barriers to completion of the requirement. Residency programs will need to grapple with these barriers to maximize benefits to residents as they prepare to become board certified.

Abstract
UK Defence Medical Services’ personnel have experienced an intense exposure to patients injured during war over the last decade and a half. As some bitter lessons of war surgery were relearned and innovative practices introduced, outcomes for patients impr oved consistently as experience accumulated. The repository of many of the enduring lessons learnt at the Role 4 echelon of care remain at the Queen Elizabeth Hospital Birmingham (QEHB), with the National Health Service and Defence Medical Services personnel who treated the returning casualties. On 22 May 2017, a terrorist detonated an improvised explosive device at the Manchester Arena, killing 22 and wounding 159 people. In the aftermath of the event, QEHB was requested to provide support to the Manchester clinicians and teleconferencing and then two clinical visits were arranged. This short report describes the nature of the visits, outlines the principles of Military Aid to the Civil Authority and looks to the future role of the Defence Medical Services in planning and response to UK terrorism events.

Abstract
Non-pharmacological techniques in the management of hypertension have been shown to be beneficial. This pilot study was set up to examine how often routine advice was given with respect to weight reduction and/or lifestyle adjustments, and whether it was heeded. Three-quarters of the 69 patients in the study smoked or were overweight but only half of the smokers recalled advice to stop. One-fifth of the patients were apparently not told to lose weight. Only one-third recalled being told to reduce alcohol intake. Lifestyle counselling and the management of hypertension in this small study appeared to be not completely effective for various reasons. It is likely to be cheaper and more satisfactory than medication alone or as an adjunct and its application deserves further study.

Abstract
AIMS The aim of this study was to describe the epidemiology of closed isolated fractures of the femoral shaft in children, and to compare the treatment and length of stay (LOS) between major trauma centres (MTCs) and trauma units (TUs) in England. PATIENTS AND METHODS National data were obtained from the Trauma and Audit Research Network for all isolated, closed fractures of the femoral shaft in children from birth to 15 years of age, between 2012 and 2015. Age, gender, the season in which the fracture occurred, non-accidental injury, the mechanism of injury, hospital trauma status, LOS and type of treatment were recorded. RESULTS A total of 1852 fractures were identified. The mean annual incidence was 5.82 per 100 000 children (95% confidence interval (CI) 5.20 to 6.44). The age of peak incidence was two years for both boys and girls; this decreased with increasing age. Children aged four to six years treated in MTCs were more likely to be managed with open reduction and internal fixation compared with those treated in TUs (odds ratio 3.20; 95% CI 1.12 to 9.14; p = 0.03). The median LOS was significantly less in MTCs than in TUs for children aged between 18 months and three years treated in both a spica (p = 0.005) and traction (p = 0.0004). CONCLUSION This study highlights the current national trends in the management of closed isolated fractures of the femoral shaft in children following activation of major trauma networks in 2012. Future studies focusing on the reasons for the differences which have been identified may help to achieve more consistency in the management of these injuries across the trauma networks.

Abstract
This article describes a new technique for quantifying creative collaboration and applies it to the user study evaluation of a co-creative drawing agent. We present a cognitive framework called
creative sense-making
that provides a new method to visualize and quantify the interaction dynamics of creative collaboration, for example, the rhythm of interaction, style of turn taking, and the manner in which participants are mutually making sense of a situation. The creative sense-making framework includes a qualitative coding technique, interaction coding software, an analysis method, and the cognitive theory behind these applications. This framework and analysis method are applied to empirical studies of the
Drawing Apprentice
collaborative sketching system to compare human collaboration with a co-creative AI agent vs. a Wizard of Oz setup. The analysis demonstrates how the proposed technique can be used to analyze interaction data using continuous functions (e.g., integrations and moving averages) to measure and evaluate how collaborations unfold through time.

Review article: the human intestinal virome in health and disease. Aliment Pharmacol Ther 2017; 46:800-815. [PMID: 28869283 PMCID: PMC5656937 DOI: 10.1111/apt.14280] [Citation(s) in RCA: 145] [Impact Index Per Article: 20.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Revised: 04/07/2017] [Accepted: 08/07/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND The human virome consists of animal-cell viruses causing transient infections, bacteriophage (phage) predators of bacteria and archaea, endogenous retroviruses and viruses causing persistent and latent infections. High-throughput, inexpensive, sensitive sequencing methods and metagenomics now make it possible to study the contribution dsDNA, ssDNA and RNA virus-like particles make to the human virome, and in particular the intestinal virome. AIM To review and evaluate the pioneering studies that have attempted to characterise the human virome and generated an increased interest in understanding how the intestinal virome might contribute to maintaining health, and the pathogenesis of chronic diseases. METHODS Relevant virome-related articles were selected for review following extensive language- and date-unrestricted, electronic searches of the literature. RESULTS The human intestinal virome is personalised and stable, and dominated by phages. It develops soon after birth in parallel with prokaryotic communities of the microbiota, becoming established during the first few years of life. By infecting specific populations of bacteria, phages can alter microbiota structure by killing host cells or altering their phenotype, enabling phages to contribute to maintaining intestinal homeostasis or microbial imbalance (dysbiosis), and the development of chronic infectious and autoimmune diseases including HIV infection and Crohn's disease, respectively. CONCLUSIONS Our understanding of the intestinal virome is fragmented and requires standardised methods for virus isolation and sequencing to provide a more complete picture of the virome, which is key to explaining the basis of virome-disease associations, and how enteric viruses can contribute to disease aetiologies and be rationalised as targets for interventions.

Abstract
AIMS Unicompartmental knee arthroplasty (UKA) has been successfully performed in the United States healthcare system on outpatients. Despite differences in healthcare structure and financial environment, we hypothesised that it would be feasible to replicate this success and perform UKA with safe day of surgery discharge within the NHS, in the United Kingdom. This has not been reported in any other United Kingdom centres. PATIENTS AND METHODS We report our experience of implementing a pathway to allow safe day of surgery discharge following UKA. Data were prospectively collected on 72 patients who underwent UKA as a day case between December 2011 and September 2015. RESULTS A total of 61 patients (85%) were discharged on the same day. The most common reason for failure was logistical; five patients had their operation too late in the day. Three patients failed to mobilise safely, two had inadequate control of pain and one had a leaking wound. The mean length of stay for those who were not discharged on the same day was 1.2 nights (1 to 3). During the same time, 58 patients underwent planned inpatient UKA, as they were deemed inappropriate for discharge on the day of surgery. However, three of these were safely discharged on the same day. Follow-up data, 24 hours post-operatively, were available for 70 patients; 51 (73%) reported no or mild pain, 14 (20%) had moderate pain and five (7%) had severe pain. There were no re-admissions. All patients had a high level of satisfaction. CONCLUSION We found that patients can be safely and effectively discharged on the day of surgery after UKA, with high levels of satisfaction. This clearly offers improved management of resources and financial savings to healthcare trusts. Cite this article: Bone Joint J 2017;99-B:788-92.

Abstract
INTRODUCTION Clinical clerkships that rely on community preceptors as faculty and assessors are challenged by the variability in their assessments of student performance. This workshop was designed to improve the interrater reliability of preceptors' assessment of student performance. METHODS This workshop uses a series of videos showing standardized student interactions with standardized patients and a preceptor. The videos feature a borderline satisfactory student-patient encounter and a superior student encounter. For each case, there is a video of the student providing an oral presentation of the encounter to a preceptor. The concept of a plus/delta card is also presented. Participants are asked to note positive elements of the interactions and elements needing improvement on the plus/delta card while watching the videos. Next, participants share their assessment of the students with the group using an audience response system. Group discussion allows for consensus and leads to decreased variation in preceptor assessments of each student's performance. This workshop has been delivered to preceptors in our institution as a 1-hour workshop. Additionally, a version has been presented twice at national medical teaching conferences as a faculty development workshop, instructing faculty how to facilitate the workshop. RESULTS Participant evaluations from the workshop show an increase in preceptors' awareness of specific student behaviors to observe as well as increased confidence with assessing more consistently across various student performances. DISCUSSION Using videos with standardized patients, students, and preceptors demonstrating various qualities of performance is effective in improving precision in preceptors' assessment of students in clinical settings.

Abstract
UNLABELLED Phenomenon: Medical student perspectives were sought about active learning, including concerns, challenges, perceived advantages and disadvantages, and appropriate role in the educational process. APPROACH Focus groups were conducted with students from all years and campuses of a large U.S. state medical school. FINDINGS Students had considerable experience with active learning prior to medical school and conveyed accurate understanding of the concept and its major strategies. They appreciated the potential of active learning to deepen and broaden learning and its value for long-term professional development but had significant concerns about the efficiency of the process, the clarity of expectations provided, and the importance of receiving preparatory materials. Most significantly, active learning experiences were perceived as disconnected from grading and even as impeding preparation for school and national examinations. Insights: Medical students understand the concepts of active learning and have considerable experience in several formats prior to medical school. They are generally supportive of active learning concepts but frustrated by perceived inefficiencies and lack of contribution to the urgencies of achieving optimal grades and passing United States Medical Licensing Examinations, especially Step 1.

Abstract
AIMS Childhood cancer survivors treated with haematopoietic stem cell transplantation (HSCT) and total body irradiation are at an increased risk of developing diabetes early in life due to insulin resistance and β-cell dysfunction, but the optimal screening method is unknown. The National Institute for Health and Care Excellence guidelines for community diabetes screening recommend using fasting glucose ≥ 7 mmol/l and/or HbA1c ≥ 48 mmol/mol (6.5%) for diagnosis and, fasting glucose 5.5-6.9 mmol/l or HbA1c 42-47 mmol/mol (6-6.5%) to indicate high risk. This study aimed to evaluate the sensitivities of fasting glucose and HbA1c in the diagnosis of diabetes and impaired glucose tolerance in childhood HSCT survivors. METHOD The patients were 35 (male = 19) HSCT survivors from a single UK centre under follow-up from 2006 to 2013. Patients had a median age (range) of 19.2 (13.1-26.2) years and had been treated for acute lymphoblastic (n = 31) or myeloid (n = 4) leukaemia when aged 7.8 (2.4-16.7) years. The outcome measures were oral glucose tolerance test (OGTT), fasting glucose and HbA1c . RESULTS OGTT identified 6 patients with diabetes (120-min glucose ≥ 11.1 mmol/l), 12 with impaired glucose tolerance (120-min glucose 7.8-11.0 mmol/l) and 2 with impaired fasting glucose (≥ 7 mmol/l). Fasting glucose ≥ 7 mmol/l or HbA1c ≥ 48 mmol/mol identified two of the six patients with diabetes diagnosed on OGTT. Fasting glucose ≥ 5.5 mmol/l and HbA1c ≥ 42 mmol/mol identified three and two patients, respectively, with diabetes. Only 1 of 12 patients with impaired glucose tolerance had a fasting glucose ≥ 5.5 mmol/l and none had HbA1c ≥ 42 mmol/mol (≥ 6%). CONCLUSIONS The fasting glucose and HbA1c cut-offs used in UK population screening only identified one-third of HSCT survivors with diabetes and do not identify those at risk. Diabetes screening in HSCT survivors requires standard OGTTs.

Abstract
AIMS To compare change in dietary intake, with an emphasis on food groups and food intake behaviour, over time across treatment arms in a diabetes prevention trial and to assess the differences in dietary intake among demographic groups within treatment arms. METHODS Data are from the Diabetes Prevention Program and Diabetes Prevention Program Outcomes Study. Participants were randomized to a lifestyle intervention (n = 1079), metformin (n = 1073) or placebo (n = 1082) for an average of 3 years, after which the initial results regarding the benefits of the lifestyle intervention were released and all participants were offered a modified lifestyle intervention. Dietary intake was assessed using a food frequency questionnaire at baseline and at 1, 5, 6 and 9 years after randomization. RESULTS Compared with the metformin and placebo arms, participants in the lifestyle arm maintained a lower total fat and saturated fat and a higher fibre intake up to 9 years after randomization and lower intakes of red meat and sweets were maintained for up to 5 years. Younger participants had higher intakes of poultry and lower intakes of fruits compared with their older counterparts, particularly in the lifestyle arm. Black participants tended to have lower dairy and higher poultry intakes compared with white and Hispanic participants. In the lifestyle arm, men tended to have higher grain, fruit and fish intakes than women. CONCLUSIONS Changes in nutrient intake among participants in the lifestyle intervention were maintained for up to 9 years. Younger participants reported more unhealthy diets over time and thus may benefit from additional support to achieve and maintain dietary goals.

Abstract
Periprosthetic fractures around total knee replacements were first reported more than 30 years ago. They are becoming more common. Various associated risk factors have been described. Treatment options for femoral fractures around total knee replacements include non-operative management, locked plates, retrograde intramedullary nails and revision arthroplasty. Periprosthetic fractures of the tibia and patella are also described, but are less common. This review article provides an overview of the epidemiology and frequency of periprosthetic fractures around total knee replacement, their initial assessment and the current treatment options available.

Preclinical characterisation of the GM-CSF receptor as a therapeutic target in rheumatoid arthritis. Ann Rheum Dis 2014; 74:1924-30. [PMID: 24936585 PMCID: PMC4602263 DOI: 10.1136/annrheumdis-2014-205234] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2014] [Accepted: 05/01/2014] [Indexed: 01/19/2023]
Abstract
Objective Previous work has suggested that the granulocyte macrophage colony stimulating factor (GM-CSF)–GM-CSF receptor α axis (GM-CSFRα) may provide a new therapeutic target for the treatment of rheumatoid arthritis (RA). Therefore, we investigated the cellular expression of GM-CSFRα in RA synovial tissue and investigated the effects of anti-GM-CSFRα antibody treatment in vitro and in vivo in a preclinical model of RA. Methods We compared GM-CSFRα expression on macrophages positive for CD68 or CD163 on synovial biopsy samples from patients with RA or psoriatic arthritis (PsA) to disease controls. In addition, we studied the effects of CAM-3003, an anti-GM-CSFR antibody in a collagen induced arthritis model of RA in DBA/1 mice. The pharmacokinetic profile of CAM-3003 was studied in naïve CD1(ICR) mice (see online supplement) and used to interpret the results of the pharmacodynamic studies in BALB/c mice. Results GM-CSFRα was expressed by CD68 positive and CD163 positive macrophages in the synovium, and there was a significant increase in GM-CSFRα positive cells in patients in patients with RA as well as patients with PsA compared with patients with osteoarthritis and healthy controls. In the collagen induced arthritis model there was a dose dependent reduction of clinical arthritis scores and the number of F4/80 positive macrophages in the inflamed synovium after CAM-3003 treatment. In BALB/c mice CAM-3003 inhibited recombinant GM-CSF mediated margination of peripheral blood monocytes and neutrophils. Conclusions The findings support the ongoing development of therapies aimed at interfering with GM-CSF or its receptor in various forms of arthritis, such as RA and PsA.

Abstract
BACKGROUND The relatively new paediatric LCP hip plate (Synthes GmBH Eimattstrasse 3 CH-4436 Oberdorff) is used in children, both with and without neuromuscular disease, for fixation of proximal femoral osteotomy for a variety of indications. MATERIALS AND METHODS We retrospectively reviewed the notes and radiographs of all those children who have had paediatric LCP device for the fixation of proximal femoral osteotomy and proximal femur fractures in our institution (Royal Manchester Children's Hospital), between October 2007 and July 2010, for their clinical progress, mobilization status, radiological healing and any complications. RESULTS Forty-three paediatric LCP hip plates were used in 40 patients (27 males and 13 females) for the fixation of 40 proximal femoral osteotomies and three proximal femur fractures. This included 13 children with underlying neuromuscular pathology and 27 children without neuromuscular disease. All osteotomies and fractures radiologically healed within 6 months [majority (n = 40) within 3 months]. There was no statistically significant difference (p = 0.45) in the neck shaft angle between the immediately post-operative and final X-rays after completion of bone healing. There were no implant-related complications both in patients with and without neuromuscular disease. No metalwork loosening was observed and no plate revisions were required. Three post-operative fractures occurred in patients with neuromuscular pathology treated with post-operative plaster immobilisation. CONCLUSION The paediatric LCP hip plate provides a stable and reliable fixation of the proximal femoral osteotomy performed for a variety of paediatric orthopaedic conditions.

Gastroesophageal reflux disease: the case for improving patient education in primary care. THE JOURNAL OF FAMILY PRACTICE 2013; 62:719-725.

Abstract
PURPOSE Gastroesophageal reflux disease (GERD) affects up to 25% of the western population, and the annual expenditure for managing GERD is estimated to be more than $14 billion. Most GERD patients do not consult a specialist, but rather rely on their primary care physician for symptom management. Research has shown that many patients--regardless of diagnosis--do not fully understand what their doctors tell them and remain uncertain as to what they are supposed to do to take care of themselves. To determine if patients are adequately educated in the management of GERD, we conducted a survey. METHOD We administered a survey to patients with GERD in an outpatient setting and explored their knowledge of such management practices as modification of behavior and diet and use of medication. RESULTS Of 333 patients enrolled, 66% reported having an in-depth discussion with their primary care physician. Among patients taking a proton pump inhibitor, 85% of those who’d had an in-depth discussion were aware of the best time to take their medication, compared with only 18% of those who did not have an in-depth discussion. In addition, patients who’d had in-depth conversations were significantly more likely than those who didn’t to know some of the behavior modification measures that might improve their symptoms. CONCLUSION Our study underscores the need for primary care providers to fully discuss GERD with their patients to improve overall management of the disease.
