CAnceR IN PreGnancy (CARING) - a retrospective study of cancer diagnosed during pregnancy in the United Kingdom.

BACKGROUND: The incidence of cancer diagnosed during pregnancy is increasing. Data relating to investigation and management, as well as maternal and foetal outcomes is lacking in a United Kingdom (UK) population. METHODS: In this retrospective study we report data from 119 patients diagnosed with cancer during pregnancy from 14 cancer centres in the UK across a five-year period (2016-2020). RESULTS: Median age at diagnosis was 33 years, with breast, skin and haematological the most common primary sites. The majority of cases were new diagnoses (109 patients, 91.6%). Most patients were treated with radical intent (96 patients, 80.7%), however, gastrointestinal cancers were associated with a high rate of palliative intent treatment (63.6%). Intervention was commenced during pregnancy in 68 (57.1%) patients; 44 (37%) had surgery and 31 (26.1%) received chemotherapy. Live births occurred in 98 (81.7%) of the cases, with 54 (55.1%) of these delivered by caesarean section. Maternal mortality during the study period was 20.2%. CONCLUSIONS: This is the first pan-tumour report of diagnosis, management and outcomes of cancer diagnosed during pregnancy in the UK. Our findings demonstrate proof of concept that data collection is feasible and highlight the need for further research in this cohort of patients.

Efficacy of immune checkpoint inhibitors for the treatment of advanced melanoma in patients with concomitant chronic lymphocytic leukemia.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have revolutionized the management of advanced melanoma (AM). However, data on ICI effectiveness have largely been restricted to clinical trials, thereby excluding patients with co-existing malignancies. Chronic lymphocytic leukemia (CLL) is the most prevalent adult leukemia and is associated with increased risk of melanoma. CLL alters systemic immunity and can induce T-cell exhaustion, which may limit the efficacy of ICIs in patients with CLL. We, therefore, sought to examine the efficacy of ICI in patients with these co-occurring diagnoses. PATIENTS AND METHODS: In this international multicenter study, a retrospective review of clinical databases identified patients with concomitant diagnoses of CLL and AM treated with ICI (US-MD Anderson Cancer Center, N = 24; US-Mayo Clinic, N = 15; AUS, N = 19). Objective response rates (ORRs), assessed by RECIST v1.1, and survival outcomes [overall survival (OS) and progression-free survival (PFS)] among patients with CLL and AM were assessed. Clinical factors associated with improved ORR and survival were explored. Additionally, ORR and survival outcomes were compared between the Australian CLL/AM cohort and a control cohort of 148 Australian patients with AM alone. RESULTS: Between 1997 and 2020, 58 patients with concomitant CLL and AM were treated with ICI. ORRs were comparable between AUS-CLL/AM and AM control cohorts (53% versus 48%, P = 0.81). PFS and OS from ICI initiation were also comparable between cohorts. Among CLL/AM patients, a majority were untreated for their CLL (64%) at the time of ICI. Patients with prior history of chemoimmunotherapy treatment for CLL (19%) had significantly reduced ORRs, PFS, and OS. CONCLUSIONS: Our case series of patients with concomitant CLL and melanoma demonstrate frequent, durable clinical responses to ICI. However, those with prior chemoimmunotherapy treatment for CLL had significantly worse outcomes. We found that CLL disease course is largely unchanged by treatment with ICI.

Registry-derived stage (RD-Stage) for capturing cancer stage at diagnosis for endometrial cancer.

BACKGROUND: Capture of cancer stage at diagnosis is important yet poorly reported by health services to population-based cancer registries. In this paper we describe current completeness of stage information for endometrial cancer available in Australian cancer registries; and develop and validate a set of rules to enable cancer registry medical coders to calculate stage using data available to them (registry-derived stage or 'RD-Stage'). METHODOLOGY: Rules for deriving RD-stage (Endometrial carcinoma) were developed using the American Joint Commission on Cancer (AJCC) TNM (tumour, nodes, metastasis) Staging System (8th Edition). An expert working group comprising cancer specialists responsible for delivering cancer care, epidemiologists and medical coders reviewed and endorsed the rules. Baseline completeness of data fields required to calculate RD-Stage, and calculation of the proportion of cases for whom an RD stage could be assigned, was assessed across each Australian jurisdiction. RD-Stage (Endometrial cancer) was calculated by Victorian Cancer Registry (VCR) medical coders and compared with clinical stage recorded by the patient's treating clinician and captured in the National Gynae-Oncology Registry (NGOR). RESULTS: The necessary data completeness level for calculating RD-Stage (Endometrial carcinoma) across various Australian jurisdictions varied from 0 to 89%. Three jurisdictions captured degree of spread of cancer, rendering RD-Stage unable to be calculated. RD-Stage (Endometrial carcinoma) could not be derived for 64/485 (13%) cases and was not captured for 44/485 (9%) cases in NGOR. At stage category level (I, II, III, IV), there was concordance between RD-Stage and NGOR captured stage in 393/410 (96%) of cases (95.8%, Kendall's coefficient = 0.95). CONCLUSION: A lack of consistency in data captured by, and data sources reporting to, population-based cancer registries meant that it was not possible to provide national endometrial carcinoma stage data at diagnosis. In a sample of Victorian cases, where surgical pathology was available, there was very good concordance between RD-Stage (Endometrial carcinoma) and clinician-recorded stage data available from NGOR. RD-Stage offers promise in capturing endometrial cancer stage at diagnosis for population epidemiological purposes when it is not provided by health services, but requires more extensive validation.

Lower risk of invasive meningococcal disease during pregnancy: national prospective surveillance in England, 2011-2014.

OBJECTIVE: To describe cases of invasive meningococcal disease (IMD) in women of childbearing age and to estimate the disease incidence and relative risk of IMD in pregnant compared with non-pregnant women. DESIGN: Prospective enhanced national surveillance for IMD. SETTING: England. POPULATION: Women of reproductive age (15-44 years) with laboratory-confirmed IMD. METHODS: Public Health England conducts enhanced national surveillance for IMD in England. Laboratory-confirmed cases are followed up with postal questionnaires to general practitioners. All cases confirmed in women of reproductive age from 1 January 2011 to 31 December 2014 were included. MAIN OUTCOME MEASURES: Annual IMD incidence and relative risk of IMD in pregnant compared with non-pregnant women of reproductive age. RESULTS: During the 4-year surveillance period, there were 1502 cases of IMD in females across England; of these, 310 (20.6%) cases were in women of reproductive age, including four women who were pregnant at the time of IMD confirmation (1.3%). Serogroup distribution of IMD cases in women of childbearing age was similar to the overall distribution. The four cases in otherwise healthy pregnant women were confirmed across all trimesters and all survived; one case in the first trimester had a septic miscarriage. The incidence of IMD was lower in pregnant than in non-pregnant women (0.16 compared with 0.76 per 100 000 pregnant and non-pregnant years, respectively), giving a lower risk of IMD in pregnant women (incidence rate ratio, IRR, 0.21; 95% confidence interval, 0.06-0.54). CONCLUSIONS: Pregnant women are nearly five times less likely to develop IMD compared with non-pregnant women, but the infection can be severe. TWEETABLE ABSTRACT: The risk of meningococcal disease is lower in pregnant women compared with non-pregnant women; the infection can occur across all trimesters and can be severe.

Quality of life in bipolar disorder: towards a dynamic understanding.

BACKGROUND: Although quality of life (QoL) is receiving increasing attention in bipolar disorder (BD) research and practice, little is known about its naturalistic trajectory. The dual aims of this study were to prospectively investigate: (a) the trajectory of QoL under guideline-driven treatment and (b) the dynamic relationship between mood symptoms and QoL. METHODS: In total, 362 patients with BD receiving guideline-driven treatment were prospectively followed at 3-month intervals for up to 5 years. Mental (Mental Component Score - MCS) and physical (Physical Component Score - PCS) QoL were measured using the self-report SF-36. Clinician-rated symptom data were recorded for mania and depression. Multilevel modelling was used to analyse MCS and PCS over time, QoL trajectories predicted by time-lagged symptoms, and symptom trajectories predicted by time-lagged QoL. RESULTS: MCS exhibited a positive trajectory, while PCS worsened over time. Investigation of temporal relationships between QoL and symptoms suggested bidirectional effects: earlier depressive symptoms were negatively associated with mental QoL, and earlier manic symptoms were negatively associated with physical QoL. Importantly, earlier MCS and PCS were both negatively associated with downstream symptoms of mania and depression. CONCLUSIONS: The present investigation illustrates real-world outcomes for QoL under guideline-driven BD treatment: improvements in mental QoL and decrements in physical QoL were observed. The data permitted investigation of dynamic interactions between QoL and symptoms, generating novel evidence for bidirectional effects and encouraging further research into this important interplay. Investigation of relevant time-varying covariates (e.g. medications) was beyond scope. Future research should investigate possible determinants of QoL and the interplay between symptoms and wellbeing/satisfaction-centric measures of QoL.

Australian multicentre study of current real-world prophylaxis practice in severe and moderate haemophilia A and B.

INTRODUCTION: With the emergence of novel treatment products for haemophilia and an increasing focus on the benefits of pharmacokinetic driven individualized prophylaxis, robust national data with regard to current patterns of factor consumption and adherence are required. AIM: To characterize current Australian practice with regard to use of prophylactic clotting factor infusions in patients with moderate or severe haemophilia A (HA) and haemophilia B (HB). METHODS: This was a retrospective, non-interventional study utilizing Australian Bleeding Disorder Registry (ABDR) data collected over a 12 month period. Registered and consented patients with moderate or severe HA or HB without inhibitors were included. RESULTS: A total of 718 HA (551 severe, 167 moderate) and 166 HB (87 severe, 79 moderate) patients were included. Regular prophylaxis was prescribed in 453 patients (82%) with severe HA, 42 patients (25%) with moderate HA, 66 patients (75%) with severe HB and 11 patients (14%) with moderate HB. Near universal prophylaxis was achieved in the paediatric subgroup. The mean weekly dose of factor VIII in severe HA was 84 international units/kg/wk (IU/kg/wk) vs 71 IU/kg/wk of factor IX in severe HB. Most patients on prophylaxis were treated ≥3 times/wk (HA) or 2 times/wk (HB). Non-adherence peaked in the 20-29 year age group. Older individuals on regular prophylaxis used more factor than was expected for their prescribed regimen. CONCLUSION: Prophylaxis rates in severe haemophilia are comparable with other developed nations. The benefit of a national registry is demonstrable. Furthermore research into the underlying reasons for non-compliance in young adults with haemophilia is required.

Screening for cognitive impairment in SLE using the Self-Administered Gerocognitive Exam.

Objective Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect the central nervous system in multiple ways, including causing cognitive dysfunction. Cognitive dysfunction is a common complaint of SLE patients yet diagnosis is challenging, time consuming, and costly. This study evaluated the Self-Administered Gerocognitive Exam (SAGE) as a screening test for cognitive impairment in a cohort of SLE patients. Methods A total of 118 SLE patients completed the SAGE. Providers completed the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the Systemic Lupus International Collaborative Clinics Damage Index (SLICC-DI). SAGE scores were grouped into normal (>16) and abnormal (≤16) categories. Univariate and multivariate analyses were performed. Results Of the 118 participants, 21(18%) scored ≤16 on the SAGE instrument. In univariate analysis, race, ethnicity, household income, and SLICC-DI scores were associated with the SAGE ( p < 0.05). In multivariable analysis, abnormal SAGE score was independently associated with higher SLICC-DI score (odds ratio (OR) = 1.44, 95% confidence intervals 1.04-1.99, p = 0.03)), Hispanic ethnicity (OR = 43.4, 95% CI 3.1-601, p = 0.005), and lower household income (OR = 11.9 for ≤$15,000 vs >$50,000, 95% CI 2.45-57, p = 0.002). Conclusions In SLE patients, this study demonstrates an independent relationship between neurocognitive impairment (as measured by the SAGE) and higher lupus-related damage, as measured by the SLICC-DI, and lower household income. Abnormal SAGE scores were also associated with Hispanic ethnicity. A language barrier could explain this because the SAGE instrument was conducted in English only. The SAGE was feasible to measure in the clinic setting.

Optimal duration of risperidone or olanzapine adjunctive therapy to mood stabilizer following remission of a manic episode: A CANMAT randomized double-blind trial.

Atypical antipsychotic adjunctive therapy to lithium or valproate is effective in treating acute mania. Although continuation of atypical antipsychotic adjunctive therapy after mania remission reduces relapse of mood episodes, the optimal duration is unknown. As many atypical antipsychotics cause weight gain and metabolic syndrome, they should not be continued unless the benefits outweigh the risks. This 52-week double-blind placebo-controlled trial recruited patients with bipolar I disorder (n=159) who recently remitted from a manic episode during treatment with risperidone or olanzapine adjunctive therapy to lithium or valproate. Patients were randomized to one of three conditions: discontinuation of risperidone or olanzapine and substitution with placebo at (i) entry ('0-weeks' group) or (ii) at 24 weeks after entry ('24-weeks' group) or (iii) continuation of risperidone or olanzapine for the full duration of the study ('52-weeks' group). The primary outcome measure was time to relapse of any mood episode. Compared with the 0-weeks group, the time to any mood episode was significantly longer in the 24-weeks group (hazard ratio (HR) 0.53; 95% confidence interval (CI): 0.33, 0.86) and nearly so in the 52-weeks group (HR: 0.63; 95% CI: 0.39, 1.02). The relapse rate was similar in the 52-weeks group compared with the 24-weeks group (HR: 1.18; 95% CI: 0.71, 1.99); however, sub-group analysis showed discordant results between the two antipsychotics (HR: 0.48, 95% CI: 0.17; 1.32 olanzapine patients; HR: 1.85, 95% CI: 1.00, 3.41 risperidone patients). Average weight gain was 3.2 kg in the 52-weeks group compared with a weight loss of 0.2 kg in the 0-weeks and 0.1 kg in the 24-weeks groups. These findings suggest that risperidone or olanzapine adjunctive therapy for 24 weeks is beneficial but continuation of risperidone beyond this period does not reduce the risk of relapse. Whether continuation of olanzapine beyond this period reduces relapse risk remains unclear but the potential benefit needs to be weighed against an increased risk of weight gain.

Long-term maintenance of efficacy of dapagliflozin in patients with type 2 diabetes mellitus and cardiovascular disease.

AIM: To evaluate the long-term efficacy, safety and tolerability of dapagliflozin versus placebo added to usual care in patients with type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). METHODS: Data were pooled from two phase III studies (NCT01031680 and NCT01042977) in high-risk patients (N = 1887) with T2DM and CVD treated with dapagliflozin (10 mg/day) or placebo. Patients completing the double-blind treatment studies (24 weeks) entered one or two sequential double-blind, long-term (LT) extensions of 28 (LT1; n = 1649) and 52 (LT2; n = 568) weeks. RESULTS: Baseline and CVD characteristics were similar in the two groups. Patients entering LT1 and LT2 on dapagliflozin maintained a greater mean reduction in glycated haemoglobin (HbA1c) versus placebo at 52 weeks [LT1, -0.58% (95% confidence interval -0.68, -0.49)] and 104 weeks [LT2, -0.35% (95% confidence interval -0.59, -0.12)]. Mean body weight and systolic blood pressure (SBP) reductions versus placebo were maintained in patients entering LT1 (52 weeks; -2.23 kg and -3.25 mmHg, respectively) and LT2 (104 weeks; -3.16 kg and -2.03 mmHg, respectively). Patients on dapagliflozin had a better three-item composite endpoint of clinical benefit (glycaemia, weight and SBP) compared with placebo at week 24 (LT1, 10.1% vs. 1.1%) and week 104 (LT2, 6.7% vs. 1.4%). Genital and urinary tract infections were more frequent with dapagliflozin than with placebo. Events of hypoglycaemia, renal impairment/failure and volume depletion were similar between groups. CONCLUSIONS: The long-term efficacy of dapagliflozin to maintain reductions in HbA1c, SBP and body weight over 2 years, together with its tolerability profile, make dapagliflozin an appropriate option in high-risk patients with T2DM and CVD.

High sodium intake is associated with short leukocyte telomere length in overweight and obese adolescents.

BACKGROUND/OBJECTIVES: Telomere shortening has an important role in cellular aging. However, the impact of high sodium intake, an important risk factor of age-related diseases, on telomere shortening remains unknown. Therefore, we examined the relationship between high dietary sodium intake and leukocyte telomere length (LTL), particularly in the context of obesity, as obesity increases salt sensitivity. SUBJECTS/METHODS: LTL was determined by a quantitative polymerase chain reaction method in 766 adolescents aged 14-18 years (50% females, 49% African Americans). Dietary sodium intake was assessed by seven independent 24-h dietary recalls. We divided the sample into low sodium (mean 2388±522 mg per day) or high sodium groups (mean 4142±882 mg per day) based on the median value (3280.9 mg per day). RESULTS: In the entire cohort, there was no significant association between sodium intake and LTL (r=-0.05, P=0.24). However, there was a significant interaction between sodium intake and obesity status (P=0.049). Further multiple linear regression analyses revealed that higher dietary sodium intake was associated with shorter LTL in the overweight/obese group (body mass index ⩾85th percentile, ß=-0.37, P=0.04), but not in the normal-weight group (ß=0.01, P=0.93) after adjusting for multiple confounding factors. In the overweight/obese group, LTL was significantly shorter in the high sodium intake subjects vs low sodium intake subjects (1.24±0.22 vs. 1.32±0.20, P=0.02), but not the normal-weight group (1.29±0.24 vs 1.30±0.24, P=0.69). CONCLUSIONS: Higher dietary sodium intake is associated with shorter telomere length in overweight and obese adolescents.

Spontaneous coronary artery thrombosis in the setting of active lupus mesenteric vasculitis.

A 33-year-old male with systemic lupus erythematosus (SLE) presented with acute abdominal pain and was found to have lupus mesenteric vasculitis on imaging and during exploratory laparotomy. Post laparotomy he continued to have persistent nausea and dyspepsia and an electrocardiogram showed evidence of an inferior ST elevation myocardial infarction (STEMI). Emergency cardiac catheterization showed evidence of thrombotic right coronary artery occlusion. His coronaries were otherwise normal with no evidence of underlying coronary artery disease. Extensive workup with trans-esophageal echo, serologies for antiphospholipid antibody syndrome (APS) and bubble study was negative. This effectively ruled out Libman-Sacks endocarditis, APS-induced arterial thrombus and paradoxical emboli as potential causes of his STEMI. By exclusion of other causes, the etiology of his STEMI was felt to be secondary to in-situ coronary artery thrombosis in the setting of active SLE. To the best of our knowledge, this is the first report of a patient with SLE presenting with both lupus mesenteric vasculitis and in-situ coronary arterial thrombosis in the absence of APS.

Durability and tolerability of dapagliflozin over 52 weeks as add-on to metformin and sulphonylurea in type 2 diabetes.

AIMS: To evaluate the safety and efficacy of dapagliflozin as add-on therapy to metformin plus sulphonylurea over 52 weeks. METHODS: Patients with type 2 diabetes mellitus (T2DM) using sulphonylurea and metformin received dapagliflozin 10 mg/day or placebo added to therapy for 52 weeks (24-week randomized, double-blind period plus 28-week double-blind extension). RESULTS: A total of 219 patients were randomized 1 : 1 to dapagliflozin or placebo. Over 52 weeks, glycated haemoglobin (HbA1c) and fasting plasma glucose levels showed greater improvement from baseline with dapagliflozin (-0.8% and -1.5 mmol/l) than with placebo (-0.1% and 0.6 mmol/l). More patients achieved HbA1c <7.0% with dapagliflozin (27.3%) than with placebo (11.3%) at 52 weeks. Dapagliflozin was associated with greater reductions in body weight and systolic blood pressure (-2.9 kg and -1.0 mmHg) compared with placebo (-1.0 kg and 1.1 mmHg). Greater increases in total, LDL and HDL cholesterol and decreases in triglycerides were observed with dapagliflozin (3.4, 4.8, 6.9 and -8.0%, respectively) versus placebo (1.4, 0.9, 0.6 and 2.9%, respectively). Fewer patients were rescued for failing to reach glycaemic targets with dapagliflozin (9.3%) than with placebo (44.4%). Adverse events and serious adverse events were similar between groups (dapagliflozin: 69.7 and 6.4%; placebo: 73.4 and 7.3%). More hypoglycaemic events were observed with dapagliflozin (15.6%) than with placebo (8.3%). Genital infections were reported in more patients in the dapagliflozin (10.1%) than in the placebo group (0.9%) and urinary tract infection frequency was similar in the two groups (10.1 and 11.0%). CONCLUSION: Dapagliflozin as add-on to metformin plus a sulphonylurea was well tolerated and improvement in glycaemic control was maintained over 52 weeks.

Dapagliflozin twice daily or once daily: effect on pharmacokinetics and urinary glucose excretion in healthy subjects.

The primary objective of this single-centre, open-label crossover study (NCT01072578) was to assess the effect of dapagliflozin on the amount of glucose in the blood and urine in healthy volunteers when dapagliflozin was administered once a day (10 mg) versus twice a day (5 mg every 12 h) after 5 days of dosing. At steady state, the AUC(ss)0₋24 (area under the dapagliflozin curve (0-24 hours) at steady state), C(ss,av) (average concentration at steady state) between dapagliflozin 5 mg twice daily and 10 mg once daily were similar AUC(ss)0₋24 [5 mg bid, (458.0 (28.7)) and 10 mg qd, (470.0 (28.5))] and C(ss,av) [5 mg bid 18.8 (28.9)) and 10 mg qd, (19.6(28.5))], but minimum and maximum plasma levels of dapagliflozin differed significantly. Percent inhibition of renal glucose reabsorption (%IRGRA) and total urinary glucose excretion over 24 h were similar for both doses. The relationship between the mean dapagliflozin concentration and %IRGRA and the total urinary glucose excreted was well described by a maximum effect model. The results indicate that dapagliflozin may be used for either once daily or twice daily administration.

Long-term glycaemic response and tolerability of dapagliflozin versus a sulphonylurea as add-on therapy to metformin in patients with type 2 diabetes: 4-year data.

AIMS: To assess the long-term efficacy and tolerability of dapagliflozin versus glipizide as add-on to metformin in patients with inadequately controlled type 2 diabetes. METHODS: The present study was an extension of an earlier randomized, double-blind, phase III study of dapagliflozin (n = 406) vs glipizide (n = 408) to 208 weeks (4 years). Patients continued to receive their assigned medication. No statistical treatment-group comparisons were calculated. RESULTS: At 208 weeks, dapagliflozin compared with glipizide produced sustained reductions in glycated haemoglogin (HbA1c): -0.30% [95% confidence interval (CI), -0.51 to -0.09], in total body weight: -4.38 kg (95% CI -5.31 to -3.46) and in systolic blood pressure (SBP): -3.67 mmHg (95% CI -5.92 to -1.41). The HbA1c coefficient of failure was significantly lower for dapagliflozin than for glipizide: 0.19 (95% CI 0.12-0.25) versus 0.61 (95% CI 0.49-0.72, difference -0.42; p = 0.0001). Dapagliflozin was not associated with glomerular function deterioration, while this occurred more frequently in patients in the glipizide group. Fewer patients reported hypoglycaemia in the dapagliflozin compared with the glipizide group (5.4 vs 51.5%). Genital and urinary tract infections were more common with dapagliflozin than with glipizide, but their incidence decreased with time and all events responded well to antimicrobial treatment. CONCLUSIONS: In patients completing 4 years of treatment, dapagliflozin was well tolerated and associated with sustained glycaemic efficacy and greater reductions in body weight and SBP versus glipizide.

A longitudinal cohort study evaluating the impact of a geriatrician-led residential care outreach service on acute healthcare utilisation.

BACKGROUND: over the last decade, high demand for acute healthcare services by long-term residents of residential care facilities (RCFs) has stimulated interest in exploring alternative models of care. The Residential Care Intervention Program in the Elderly (RECIPE) service provides expert outreach services to RCFs residents, interventions include comprehensive care planning, management of inter-current illness and rapid access to acute care substitution services. OBJECTIVE: to evaluate whether the RECIPE service decreased acute healthcare utilisation. DESIGN: a retrospective cohort study using interrupted time series analysis to analyse change in acute healthcare utilisation before and after enrolment. SETTING: a 300-bed metropolitan teaching hospital in Australia and 73 RCFs within its catchment. SUBJECTS: there were 1,327 patients enrolled in the service with a median age of 84 years; 61% were female. METHODS: data were collected prospectively on all enrolled patients from 2004 to 2011 and linked to the acute health service administrative data set. Primary outcomes change in admission rates, length of stay and bed days per quarter. RESULTS: in the 2 years prior to enrolment, the mean number of acute care admissions per patient per year was 3.03 (SD 2.9) versus post 2.4 (SD 3.3), the service reducing admissions by 0.13 admissions per patient per quarter (P = 0.046). Prior to enrolment, the mean length of stay was 8.6 (SD 11.0) versus post 3.5 (SD 5.0), a reduction of 1.5 days per patient per quarter (P = 0.003). CONCLUSIONS: this study suggests that an outreach service comprising a geriatrician-led multidisciplinary team can reduce acute hospital utilisation rates.

Dapagliflozin in type 2 diabetes: effectiveness across the spectrum of disease and over time.

BACKGROUND: Despite many available therapies, patients with type 2 diabetes mellitus (T2DM) frequently do not achieve/maintain glycaemic control. Furthermore, side effects such as hypoglycaemia and weight gain may limit therapy choices. Dapagliflozin, a selective sodium-glucose cotransporter-2 inhibitor, reduces hyperglycaemia by increasing glucosuria independently of insulin, representing a novel approach in T2DM. Dapagliflozin efficacy, safety and tolerability were evaluated across a wide range of clinical trials. METHODS: Dapagliflozin 10-mg efficacy data from (i) two short-term, active-comparator studies (vs. metformin-XR over 24 weeks and vs. glipizide over 52 weeks), (ii) pooled 24-week analyses of five placebo-controlled trials (as monotherapy or add-on therapy), and (iii) long-term studies over 2 years; dapagliflozin 5- and 10-mg pooled safety data from 12 placebo-controlled trials; and cardiovascular safety and malignancy data from 19 dapagliflozin studies were evaluated. RESULTS: In treatment-naïve patients (baseline HbA1c 9%), dapagliflozin reduced HbA1c (-1.45%) similarly to metformin-XR (-1.44%). In metformin-treated patients (baseline HbA1c 7.7%), dapagliflozin achieved a clinically significant reduction (-0.52%) similar to glipizide (-0.52%). In pooled 24-week analyses, dapagliflozin vs. placebo differences in HbA1c, weight and systolic blood pressure (SBP) were -0.60%, -1.61 kg and -3.6 mmHg, respectively. At 2 years, dapagliflozin vs. placebo differences in HbA1c and weight were -0.44 to -0.80% and -2.41 to -3.19 kg, respectively, and vs. glipizide, differences in HbA1c, weight, and SBP were -0.18%, -5.06 kg, and -3.89 mmHg, respectively. Major hypoglycaemia with dapagliflozin was rare (< 0.1%). Urinary tract and genital infections were more common with dapagliflozin, but responded to standard care and rarely led to study discontinuation. Events of renal failure/impairment and malignancies were rare and balanced across treatment groups. Pooled analyses did not indicate that dapagliflozin increased cardiovascular event risk. CONCLUSIONS: Dapagliflozin improved glycaemic control, decreased body weight, and lowered blood pressure across the spectrum of T2DM disease, with maintenance of these benefits over time.

Dapagliflozin in patients with type 2 diabetes receiving high doses of insulin: efficacy and safety over 2 years.

AIMS: Dapagliflozin, a selective inhibitor of sodium-glucose cotransporter 2 (SGLT2), has been shown to improve glycaemic control, stabilize insulin dosing and mitigate insulin-associated weight gain over 48 weeks in patients whose type 2 diabetes mellitus (T2DM) was inadequately controlled despite high doses of insulin. Here the efficacy and safety of dapagliflozin therapy after a total of 104 weeks are evaluated in this population. METHODS: This was a 24-week, randomized, placebo-controlled, double-blinded, multicentre trial followed by two site- and patient-blinded extension periods of 24 and 56 weeks (NCT00673231), respectively. A total of 808 patients, whose T2DM was inadequately controlled on insulin ≥30 IU/day, with or without up to two oral antidiabetic drugs, were randomly assigned to receive placebo or 2.5, 5 or 10 mg/day of dapagliflozin for 104 weeks. At 48 weeks, patients on dapagliflozin 5 mg were switched to 10 mg. Outcomes over 104 weeks included change from baseline in HbA1c, insulin dose and body weight; analyses used observed cases and included data after insulin up-titration. Adverse events (AEs) were evaluated throughout 104 weeks. RESULTS: Five hundred and thirteen patients (63.6%) completed the study. Mean HbA1c changes from baseline at 104 weeks were -0.4% in the placebo group and -0.6 to -0.8% in the dapagliflozin groups. In the placebo group, mean insulin dose increased by 18.3 IU/day and weight increased by 1.8 kg at 104 weeks, whereas in the dapagliflozin groups, insulin dose was stable and weight decreased by 0.9-1.4 kg. AEs, including hypoglycaemia, were balanced across groups. Proportions of patients with events suggestive of genital infection and of urinary tract infection (UTI) were higher with dapagliflozin versus placebo (genital infection 7.4-14.3% vs. 3.0%; UTI 8.4-13.8% vs. 5.6%) but most occurred in the first 24 weeks and most were single episodes that responded to routine management. CONCLUSIONS: Dapagliflozin improved glycaemic control, stabilized insulin dosing and reduced weight without increasing major hypoglycaemic episodes over 104 weeks in patients whose T2DM was inadequately controlled on insulin. However, rates of genital infection and of UTI were elevated with dapagliflozin therapy.

Changes in weight loss-related quality of life among type 2 diabetes mellitus patients treated with dapagliflozin.

AIMS: This study evaluated change in health-related quality of life (HRQOL) associated with ongoing weight change among patients with type 2 diabetes mellitus (T2DM) treated with dapagliflozin, a highly selective sodium-glucose cotransporter 2 (SGLT2) inhibitor that lowers blood glucose by increasing urinary glucose excretion and is associated with body weight reductions. METHODS: Patients with T2DM who had inadequate glycaemic control on metformin (MET) alone were enrolled in a 24-week, double-blind, randomized, placebo-controlled study with a 78-week extension to evaluate the effect of dapagliflozin + MET on body weight. Patients also completed the Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes Weight Questionnaire-9 (SHIELD-WQ-9), a weight change-related HRQOL survey. Difference in proportions of patients treated with dapagliflozin 10 mg + MET (n = 89) or placebo + MET (n = 91) who reported improvement in HRQOL was analysed with Fisher's exact test. RESULTS: Dapagliflozin patients had significantly greater weight loss than placebo patients over 102 weeks (p < 0.05). This corresponded to a numerically greater proportion of dapagliflozin-treated patients reporting ongoing weight loss and associated improvements in most HRQOL domains at three different evaluation points (weeks 24, 50 and 102) than placebo-treated patients. In a post-hoc analysis among patients who reported ongoing weight loss regardless of treatment arm, a significantly greater proportion of patients reporting weight loss versus weight gain reported improvements in physical health, self-esteem and overall HRQOL at weeks 24, 50 and 102. CONCLUSIONS: Dapagliflozin-induced weight loss was associated with improvement in overall HRQOL. Overall, ongoing weight loss was associated with improvements in several HRQOL domains compared with weight gain.

Dapagliflozin maintains glycaemic control while reducing weight and body fat mass over 2 years in patients with type 2 diabetes mellitus inadequately controlled on metformin.

AIMS: Dapagliflozin, a highly selective inhibitor of sodium-glucose cotransporter 2 (SGLT2), reduces hyperglycaemia and weight in patients with type 2 diabetes mellitus (T2DM) by increasing urinary glucose excretion. Long-term glycaemic control, body composition and bone safety were evaluated in patients with T2DM after 102 weeks of dapagliflozin treatment. METHODS: This randomized, double-blind, placebo-controlled study (NCT00855166) enrolled patients with T2DM [mean: age 60.7 years; HbA1c 7.2%; body mass index (BMI) 31.9 kg/m(2) ; body weight 91.5 kg] inadequately controlled on metformin. Patients (N = 182) were randomly assigned 1 : 1 to receive dapagliflozin 10 mg/day or placebo added to open-label metformin for a 24-week double-blind treatment period followed by a 78-week site- and patient-blinded extension period. At week 102, changes from baseline in HbA1c, weight, waist circumference, total body fat mass as measured by dual-energy X-ray absorptiometry (DXA), serum markers of bone turnover, bone mineral density (BMD) as measured by DXA, and adverse events were evaluated. RESULTS: A total of 140 patients (76.9%) completed the study. Over 102 weeks, dapagliflozin-treated patients showed reductions in HbA1c by -0.3%, weight by -4.54 kg, waist circumference by -5.0 cm and fat mass by -2.80 kg without increase in rate of hypoglycaemia. Compared with placebo, no meaningful changes from baseline in markers of bone turnover or BMD were identified over 102 weeks. One fracture occurred in each treatment group. The frequency of urinary tract infection (UTI) and genital infection was similar in both treatment groups. CONCLUSIONS: Over 102 weeks, dapagliflozin improved glycaemic control, and reduced weight and fat mass, without affecting markers of bone turnover or BMD in patients with T2DM inadequately controlled on metformin.
