Proton Pump Inhibitors in Germany: Status Quo of a Growing Market. Health Serv Res Manag Epidemiol 2024; 11:23333928241241220. [PMID: 38562150 PMCID: PMC10983788 DOI: 10.1177/23333928241241220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 02/12/2024] [Accepted: 03/05/2024] [Indexed: 04/04/2024] Open
Abstract
Introduction The volume of prescriptions for proton pump inhibitors (PPIs) remains high, although the literature increasingly points to excessive prescribing in relation to guideline recommendations. No very recent data is available on the specific situation in Germany, particularly on the proportion of PPI consumption from over-the-counter (OTC) sales and self-selection, following PPI down-scheduling. The aim of this study was to determine the actual amount of prescribed and OTC PPIs in Germany. Methods For this retrospective study, several IQVIA databases were used, representing all prescriptions billed to statutory and private health insurers in Germany, as well as OTC sales. Analyses were performed for the period November 2020 to October 2021 or partially November 2018 to October 2021 and were descriptive in nature. Mainly, data were collected from IQVIATM PharmaScope National® as well as IQVIA TM DPM® databases. Results A total of 2.87 billion PPI tablets were shown to have been sold between November 2020 and October 2021, with most drugs prescribed in the largest packages and strengths. In addition, the OTC PPI market increased by an average of 14% per year over a 3-year period. Conclusions The results of this study suggest the substantial size of the PPI market in Germany is based on prescriptions, a consistent increase in OTC PPI purchases and a recent increase in prescriptions.

Topical Alginate Protection against Pepsin-Mediated Esophageal Damage: E-Cadherin Proteolysis and Matrix Metalloproteinase Induction. Int J Mol Sci 2023; 24:ijms24097932. [PMID: 37175640 PMCID: PMC10178445 DOI: 10.3390/ijms24097932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/18/2023] [Accepted: 04/25/2023] [Indexed: 05/15/2023] Open
Abstract
Epithelial barrier dysfunction is a hallmark of gastroesophageal reflux disease (GERD) related to symptom origination, inflammatory remodeling and carcinogenesis. Alginate-based antireflux medications were previously shown to topically protect against peptic barrier disruption, yet the molecular mechanisms of injury and protection were unclear. Herein, Barrett's esophageal (BAR-T) cells were pretreated with buffered saline (HBSS; control), dilute alginate medications (Gaviscon Advance or Gaviscon Double Action, Reckitt Benckiser), a viscosity-matched placebo, or ADAM10 and matrix metalloproteinase (MMP) inhibitors before exposure to HBSS pH7.4 or pH4 ± 1 mg/mL pepsin for 10-60 min. Cell viability was assessed by ATP assay; mediators of epithelial integrity, E-cadherin, ADAM10, and MMPs were examined by Western blot and qPCR. Alginate rescued peptic reduction of cell viability (p < 0.0001). Pepsin-pH4 yielded E-cadherin fragments indicative of regulated intramembrane proteolysis (RIP) which was not rescued by inhibitors of known E-cadherin sheddases. Transcriptional targets of E-cadherin RIP fragments were elevated at 24 h (MMP-1,2,9,14; p < 0.01). Alginate rescued E-cadherin cleavage, ADAM10 maturation, and MMP induction (p < 0.01). Results support RIP as a novel mechanism of peptic injury during GERD. Alginate residue after wash-out to mimic physiologic esophageal clearance conferred lasting protection against pepsin-induced molecular mechanisms that may exacerbate GERD severity and promote carcinogenesis in the context of weakly acidic reflux.

Randomised clinical trial: the use of alginates during preinvestigation proton pump inhibitor wash-out and their impact on compliance and symptom burden. BMJ Open Gastroenterol 2023; 10:bmjgast-2022-001026. [PMID: 36627148 PMCID: PMC9835863 DOI: 10.1136/bmjgast-2022-001026] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 11/18/2022] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND/AIMS Investigation of gastro-oesophageal reflux disease is usually performed off proton pump inhibitors (PPIs). This can exacerbate symptoms, potentially impacting investigation accuracy if patients circumvent the preinvestigation instructions. There are no standard recommendations on how to manage PPI withdrawal. We aimed to assess the impact of structured alginate use on symptom burden. METHODS Participants were already established on ≥4 weeks of PPI therapy and being referred for manometry and 24-hour pH/impedance testing. Preinvestigation instructions involved stopping PPIs and H2 receptor antagonists for 1 week, but antacids and alginates were allowed until the night before. Participants were randomised to follow these standard instructions (control group), or the same instructions with the provision of Gaviscon Advance to be taken four times daily (treatment group). The primary outcome assessed change in Gastro-Oesophageal Reflux Disease Health-Related Quality of Life Score. KEY RESULTS Data for 48 patients were available for primary outcome assessment. While patients in the control group had a significant increase in symptoms (median difference 6.5, 95% CI (1 to 7), p=0.04), no change occurred in the treatment arm (median difference -1.5, 95% CI (-2, 3.5), p=0.54). There were no serious adverse events. CONCLUSIONS Structured alginate use prevents symptom exacerbation during preinvestigation PPI wash-out. These findings are limited to the 1-week wash-out period but can benefit thousands of patients undergoing investigation for gastro-oesophageal reflux each year. Further research is required to assess this effect in other settings, such as sustained PPI deprescription. The trial was funded by Reckitt Benckiser. TRIAL REGISTRATION NUMBER EudraCT registration 2019-004561-41.

Prescribing Patterns of Proton Pump Inhibitors in Germany: A Retrospective Study Including 472 146 Patients. J Prim Care Community Health 2023; 14:21501319231221002. [PMID: 38142444 PMCID: PMC10749518 DOI: 10.1177/21501319231221002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 11/27/2023] [Accepted: 11/29/2023] [Indexed: 12/26/2023] Open
Abstract
The aims of this study were to analyze proton pump inhibitor (PPI) users in Germany, defining and classifying them in terms of treatment appropriateness, and to analyze the PPI prescription practices of healthcare providers. The updated DGVS (Deutsche Gesellschaft für Gastroenterologie, Verdauungs-und Stoffwechselkrankheiten) gastroesophageal reflux disease (GERD) treatment guideline (published March 2023) for mild heartburn symptoms recommends carrying out a probatory treatment of mild symptoms via other medication such as antacids, alginates, and H2 blockers before escalating to PPI treatments, if the patient profile allows. This retrospective cross-sectional study was based on data from the IQVIA™ Disease Analyzer database (DA) and included adult patients (18 years or older) in 1006 general and 39 gastroenterological practices in Germany who received at least 1 PPI prescription or alginate between September 2019 and September 2021 (hereinafter referred to as the index period). Analyses included indications associated with PPI prescription, co-diagnoses, co-therapies of PPI patients, duration of PPI therapy, dosages of PPI prescriptions, and proportions of practices prescribing PPIs and alginates. A total of 472 146 patients taking PPIs and 9101 patients taking alginates were available for analysis. Very few patients (4.5%) of the total cohort were treated in complete adherence to treatment guidelines. Conditions such as gastritis and duodenitis (47.2%) and reflux diseases (38.4%) were more frequently associated with PPI prescriptions. The average PPI treatment period lasted 141 days, and 36.6% of patients were treated for >6 months. High doses were prescribed relatively often (ie, 42.8% of esomeprazole prescriptions were 40 mg, 59.1% of lansoprazole prescriptions 30 mg, 28.6% of omeprazole prescriptions 40 mg). With each practice prescribing PPIs to at least 10% of their patients; 72% of general practitioners (GPs) and 8% of GENTS (Gastroenterologists) prescribed alginates. This study highlights that discrepancies exist between clinical guidelines and real-life prescribing practices of PPIs in Germany. Particular attention should be given to the incidence of patients being prescribed high-dose or long-duration PPI with mild indications. These findings are particularly apt considering the publication (March 2023) of new guidelines on the "management of gastroesophageal reflux disease and eosinophilic esophagitis," by the DGVS.

Alginates for Protection Against Pepsin-Acid Induced Aerodigestive Epithelial Barrier Disruption. Laryngoscope 2022; 132:2327-2334. [PMID: 35238407 DOI: 10.1002/lary.30087] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 02/17/2022] [Accepted: 02/21/2022] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) are chronic conditions caused by backflow of gastric and duodenal contents into the esophagus and proximal aerodigestive tract, respectively. Mucosal barrier dysfunction resultant from the synergistic actions of chemical injury and the mucosal inflammatory response during reflux contributes to symptom perception. Alginates effectively treat symptoms of mild to moderate GERD and have recently shown benefit for LPR. In addition to forming a "raft" over gastric contents to reduce acidic reflux episodes, alginates have been found to bind the esophageal mucosa thereby preserving functional barrier integrity measured by transepithelial electrical resistance. The aim of this study was to further examine the topical protective capacity of alginate-based Gaviscon Advance (GA) and Double Action (GDA) against pepsin-acid mediated aerodigestive epithelial barrier dysfunction in vitro. STUDY DESIGN Translational. METHODS Immortalized human esophageal and vocal cord epithelial cells cultured in transwells were pretreated with liquid formula GA, GDA, matched viscous placebo solution, or saline (control), then treated for 1 h with saline, acid (pH 3-6) or pepsin (0.1-1 mg/ml) at pH 3-6. Endpoint measure was taken of horseradish peroxidase (HRP) allowed to diffuse across monolayers for 2 h. RESULTS Pepsin (0.1-1 mg/ml) at pH 3-6 increased HRP flux through cultures pretreated with saline or placebo (p < 0.05); acid alone did not. GA and GDA prevented barrier dysfunction. CONCLUSIONS GA and GDA preserved epithelial barrier function during pepsin-acid insult better than placebo suggesting that protection was due to alginate. These data support topical protection as a therapeutic approach to GERD and LPR. Laryngoscope, 132:2327-2334, 2022.

Abstract
INTRODUCTION Proton pump inhibitors (PPIs) used in the management of gastro-esophageal reflux disease (GORD) are among the most frequently prescribed classes of drug worldwide. Currently, however, physicians are prescribing PPIs for extended periods, often without an indication, which is not in line with current guidance and therefore preventing appropriate reflux management. Inappropriate or excessive PPI prescribing is becoming increasingly visible, yet there is currently little research available on the impact such current practice has on the patient experience. This study aims to understand patient attitudes toward their PPI treatment and the impact current PPI prescribing patterns have on the patient experience. METHODS An online survey of current and previous users of PPI for GORD was conducted in the UK and Germany. Topics covered included prior steps taken before first consultation with a physician, initial recommendations, PPI treatment initiation and duration, use of PPI, management of reflux whilst taking a PPI, stopping PPI treatment, and patient attitudes. RESULTS Among 566 patient participants (UK, n = 372; Germany, n = 194) 69% to 79% reported being prescribed medication at their first visit to a physician, of which 61% to 68% were prescribed a PPI either alone or combined with another treatment. 41% to 48% of patients answered "don't know" when asked how long they expected to continue taking their PPI. 49% to 50% of patients currently on PPIs also reported having concerns with regards to long-term treatment. 70% of patients recalled being well informed on dosage and treatment regimens. However, other safety and usage information was reported as being less frequently discussed. CONCLUSIONS Although patients reported concerns regarding ongoing long-term PPI treatment, this was not reflected in the prescribing pattern from physicians. More can be done to ensure patients are fully informed about their PPI treatment at consultation. Findings also suggest a disconnect exists between standard treatment guidelines and prescribing patterns, as experienced by patients.

A Novel In Vitro Model for Determining the Optimum pH and Dose Volume of New Liquid Alginate for Infant Reflux Suppression. Drugs R D 2021; 21:331-339.

Abstract
BACKGROUND Gastroesophageal reflux frequently occurs in infants from birth to 2 years and is characterised by reflux and regurgitation often occurring during or immediately after feeds. These reflux events can range in both frequency and severity, and as the reflux events increase, they become increasingly distressing for both the infant and the parent. The study aimed to characterise the properties of a new infant liquid alginate product, determining the optimum gastric pH and dose volume for maximum reflux suppressant activity. METHODS An in vitro infant stomach model was designed and developed that allowed products to be assessed for their reflux suppression activity. The validation of the model was completed by three independent operators comparing a milk control with infant Gaviscon to evaluate the models' robustness, reproducibility, and ease of use. The model was used to establish reflux suppression activity of a new liquid alginate infant formulation in comparison with a milk control. Suppression activity was assessed at varying doses and pH within a physiological range. RESULTS The validation study demonstrated no significant difference in refluxate volumes for the milk control within each reflux event when comparing across the three individual operators. Similarly, no statistical differences were seen during the infant Gaviscon experiments, confirming the robustness and reproducibility of the model. Significant reflux suppression was seen across the pH range (except at pH 5.75); the pH most advantageous for reflux suppression was pH 5.25. The optimum dose volume for consistently suppressing reflux was shown to be 5 ml. An infant stomach model was designed for evaluating reflux suppression activity of a formulation of liquid alginate. The optimum gastric pH and dose volume for demonstrating significant reflux suppression and the thickening of formula milk by the infant liquid alginate formulation were established. CONCLUSION This study confirms the mode of action of the alginate formula, demonstrating a superior reduction in the retrograde movement of in vitro gastric contents and volume of regurgitation. The study also demonstrates that optimal performance occurs in conditions that are in line physiologically with the target patient. Both actions compliment and support the efficacy of the alginate formulation as a reflux therapy agent.

Duration of adhesion of swallowed alginates to distal oesophageal mucosa: implications for topical therapy of oesophageal diseases. Aliment Pharmacol Ther 2020; 52:442-448. [PMID: 32548849 DOI: 10.1111/apt.15884] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 05/18/2020] [Accepted: 05/24/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND We have previously shown, ex vivo, that alginate solutions can have a topical protective effect on oesophageal mucosal biopsies exposed to simulated gastric juice. Oesophageal mucosal impedance can measure the duration of mucosal adherence of ionic solutions since the impedance drops when the solution is present, and rises to baseline as the solution clears. AIM To investigate the in vivo duration of adhesion of swallowed alginate solution to distal oesophageal mucosa. METHODS We studied 20 healthy volunteers and 10 patients with heartburn. A pH-impedance catheter was inserted, and baseline distal channel oesophageal impedance measured. Healthy volunteers received 10 mL of either sodium alginate (Gaviscon Advance), Gaviscon placebo (no alginate) or viscous slurry (saline mixed with sucralose), given in a randomised, single-blinded order over three visits. Patients received either sodium alginate or placebo on two visits. Initial impedance drop was measured, then 1-minute mean impedance was measured each minute until ≥75% recovery to baseline. RESULTS In healthy volunteers, sodium alginate adhered to the oesophageal mucosa for longer than placebo or viscous slurry (10.4 [8.7] minutes vs 1.1 [1.6] vs 3.6 [4.0], P < 0.01). In patients, sodium alginate adhered to the oesophageal mucosa for longer than placebo (9.0 (5.4) vs 3.7 (4.1), P < 0.01). CONCLUSIONS Sodium alginate solution adhered to the oesophageal mucosa for significantly longer than placebo or viscous slurry. This demonstrates that alginates could confer a protective benefit due to mucoadhesion and can be a basis for further development of topical protectants and for topical drug delivery in oesophageal disease.

Abstract
BACKGROUND Late-night supper increases the risk of postprandial reflux from the acid pocket especially in obesity. An alginate-based, raft-forming medication may be useful for obese patients with GERD. AIMS To compare the efficacy of Gaviscon Advance (Reckitt Benckiser, UK) and a non-alginate antacid in post-supper suppression of the acid pocket and post-prandial reflux among obese participants. METHODS Participants underwent 48 h wireless and probe-based pH-metry recording of the acid pocket and lower oesophagus, respectively, and were randomised to single post-supper (10 pm) dose of either Gaviscon Advance or a non-alginate antacid on the second night. Primary outcomes were suppression of median pH of acid pocket and lower oesophagus, measured every 10-minutes post-supper for 1 h. Secondary outcomes were suppression of % time pH < 4 at lower oesophagus and improvement in frequency and visual analogue score (VAS) of regurgitation. RESULTS Of the 81 screened participants, 55 were excluded and 26 (mean age 33.5 years, males 77.8% and BMI 32.8 kg/m2 ) were randomised to Gaviscon Advance (n = 13) or antacid (n = 13). Median pH of the acid pocket but not the lower oesophagus was suppressed with Gaviscon Advance vs antacid (all P < 0.04) Gaviscon Advance but not antacid significantly reduced in % time pH < 4, symptom frequency and VAS on day 2 vs day 1 (all P < 0.05). CONCLUSIONS Among obese individuals, Gaviscon Advance was superior to a non-alginate antacid in post-supper suppression of the acid pocket.

Abstract
Background Gastroesophageal reflux disease (GORD) is a common condition affecting 30% of infants aged 0–23 months. The Infant Gastroesophageal Questionnaire Revised version (I-GERQ-R) is an observer-reported outcome measures (ObsRO) developed to evaluate the impact of GORD on young infants. However, evidence regarding the clinically important difference (CID) for the I-GERQ-R is limited. The aim of this study was to determine a CID for the I-GERQ-R. Methods A literature review was undertaken (PsycInfo, Embase, MedLine and EconLit databases) for longitudinal studies involving the I-GERQ-R. Articles were not limited by language or publication date. A random effects model was applied to calculate an overall CID, along with I2 and Q statistics. Publication bias was also assessed. Results The search identified 42 articles; 11 were selected for full-text review and 7 articles were identified for full data extraction. The studies included a total of 661 infants (range: 30 to 313); 424 infants had been diagnosed with GORD (64%). The age range of the infants across the studies was from birth to 7 months. The overall CID was −6.54 (95% confidence interval: −4.35 to −8.74), Q = 17.96, p=0.08 and I2=22.04. Conclusion This study derived a CID for the I-GERQ-R and indicated a threshold around 6 could signify a clinically important difference for this instrument. The lower limit of the 95% confidence interval suggested a threshold of 3 to 4 could represent a minimally important difference. These results may help inform clinical decisions in evaluating meaningful change in symptom severity in children affected by GORD.

Abstract
OBJECTIVE To investigate the intragastric acid neutralization activity of a combined alginate-antacid formulation. SIGNIFICANCE Published studies have investigated the reflux-suppressing alginate component of Gaviscon Double Action (Gaviscon DA; RB, UK) but intragastric acid neutralization activity of the antacid component has not been evaluated in vivo. METHODS Intragastric pH monitoring, using a custom-made 10-electrode catheter, was evaluated in a two-part exploratory study in healthy subjects; Part I (n = 6) tested suitability of the catheter using antacid tablets (Rennie; Bayer, Germany); Part II (n = 12) evaluated gastric acid neutralization activity of Gaviscon DA liquid (20 ml) versus placebo in fasted subjects using a randomized, open-label, crossover design. The primary endpoint was the percentage of time that intragastric pH ≥4 was measured during 30 min post-treatment. A confirmatory study of identical design was subsequently conducted (n = 20). RESULTS Monitoring pH using the multielectrode catheter was a viable approach, directly detecting changes in intragastric pH following a single dose of antacid tablets. In the exploratory study, the percentage of time that pH ≥4 during 30 minutes post-treatment was 46.8% with Gaviscon DA liquid versus 4.7% with placebo (p = 0.0004). These findings were supported by the confirmatory study, where pH ≥4 was recorded 50.8% of the time with Gaviscon DA versus 3.5% with placebo (p = 0.0051). In this study, Gaviscon DA was safe and well tolerated. CONCLUSIONS These studies demonstrate the effective acid neutralizing capacity of Gaviscon DA versus placebo in healthy, fasted subjects. This adds to the evidence base for the combination of alginates and antacids.

Co-enrolment of Participants into Multiple Cancer Trials: Benefits and Challenges. Clin Oncol (R Coll Radiol) 2017; 29:e126-e133. [PMID: 28314597 PMCID: PMC5479364 DOI: 10.1016/j.clon.2017.02.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 02/14/2017] [Accepted: 02/16/2017] [Indexed: 11/17/2022]
Abstract
Opportunities to enter patients into more than one clinical trial are not routinely considered in cancer research and experiences with co-enrolment are rarely reported. Potential benefits of allowing appropriate co-enrolment have been identified in other settings but there is a lack of evidence base or guidance to inform these decisions in oncology. Here, we discuss the benefits and challenges associated with co-enrolment based on experiences in the Add-Aspirin trial - a large, multicentre trial recruiting across a number of tumour types, where opportunities to co-enrol patients have been proactively explored and managed. The potential benefits of co-enrolment include: improving recruitment feasibility; increased opportunities for patients to participate in trials; and collection of robust data on combinations of interventions, which will ensure the ongoing relevance of individual trials and provide more cohesive evidence to guide the management of future patients. There are a number of perceived barriers to co-enrolment in terms of scientific, safety and ethical issues, which warrant consideration on a trial-by-trial basis. In many cases, any potential effect on the results of the trials will be negligible - limited by a number of factors, including the overlap in trial cohorts. Participant representatives stress the importance of autonomy to decide about trial enrolment, providing a compelling argument for offering co-enrolment where there are multiple trials that are relevant to a patient and no concerns regarding safety or the integrity of the trials. A number of measures are proposed for managing and monitoring co-enrolment. Ensuring acceptability to (potential) participants is paramount. Opportunities to enter patients into more than one cancer trial should be considered more routinely. Where planned and managed appropriately, co-enrolment can offer a number of benefits in terms of both scientific value and efficiency of study conduct, and will increase the opportunities for patients to participate in, and benefit from, clinical research.

Randomised clinical trial: addition of alginate-antacid (Gaviscon Double Action) to proton pump inhibitor therapy in patients with breakthrough symptoms. Aliment Pharmacol Ther 2017; 45:1524-1533.

Abstract
BACKGROUND Symptomatic breakthrough in proton pump inhibitor (PPI)-treated gastro-oesophageal reflux disease (GERD) patients is a common problem with a range of underlying causes. The nonsystemic, raft-forming action of alginates may help resolve symptoms. AIM To assess alginate-antacid (Gaviscon Double Action, RB, Slough, UK) as add-on therapy to once-daily PPI for suppression of breakthrough reflux symptoms. METHODS In two randomised, double-blind studies (exploratory, n=52; confirmatory, n=262), patients taking standard-dose PPI who had breakthrough symptoms, assessed by Heartburn Reflux Dyspepsia Questionnaire (HRDQ), were randomised to add-on Gaviscon or placebo (20 mL after meals and bedtime). The exploratory study endpoint was change in HRDQ score during treatment vs run-in. The confirmatory study endpoint was "response" defined as ≥3 days reduction in the number of "bad" days (HRDQ [heartburn/regurgitation] >0.70) during treatment vs run-in. RESULTS In the exploratory study, significantly greater reductions in HRDQ scores (heartburn/regurgitation) were observed in the Gaviscon vs placebo (least squares mean difference [95% CI] -2.10 [-3.71 to -0.48]; P=.012). Post hoc "responder" analysis of the exploratory study also revealed significantly more Gaviscon patients (75%) achieved ≥3 days reduction in "bad" days vs placebo patients (36%), P=.005. In the confirmatory study, symptomatic improvement was observed with add-on Gaviscon (51%) but there was no significant difference in response vs placebo (48%) (OR (95% CI) 1.15 (0.69-1.91), P=.5939). CONCLUSIONS Adding Gaviscon to PPI reduced breakthrough GERD symptoms but a nearly equal response was observed for placebo. Response to intervention may vary according to whether symptoms are functional in origin.

Metformin as an adjuvant treatment for cancer: a systematic review and meta-analysis. Ann Oncol 2016; 27:2184-2195.

Abstract
BACKGROUND Metformin use has been associated with a reduced risk of developing cancer and an improvement in overall cancer survival rates in meta-analyses, but, to date, evidence to support the use of metformin as an adjuvant therapy in individual cancer types has not been presented. PATIENTS AND METHODS We systematically searched research databases, conference abstracts and trial registries for any studies reporting cancer outcomes for individual tumour types in metformin users compared with non-users, and extracted data on patients with early-stage cancer. Studies were assessed for design and quality, and a meta-analysis was conducted to quantify the adjuvant effect of metformin on recurrence-free survival (RFS), overall survival (OS) and cancer-specific survival (CSS), to inform future trial design. RESULTS Of 7670 articles screened, 27 eligible studies were identified comprising 24 178 participants, all enrolled in observational studies. In those with early-stage colorectal cancer, metformin use was associated with a significant benefit in all outcomes [RFS hazard ratio (HR) 0.63, 95% confidence interval (CI) 0.47-0.85; OS HR 0.69, CI 0.58-0.83; CSS HR 0.58, CI 0.39-0.86]. For men with early-stage prostate cancer, metformin was associated with significant, or borderline significant, benefits in all outcomes (RFS HR 0.83, CI 0.69-1.00; OS HR 0.82, CI 0.73-0.93; CSS HR 0.58, CI 0.37-0.93); however, there was significant heterogeneity between studies. The data suggest that prostate cancer patients treated with radical radiotherapy may benefit more from metformin (RFS HR 0.45, CI 0.29-0.70). In breast and urothelial cancer, no significant benefits were identified. Sufficient data were not available to conduct analyses on the impact of metformin dose and duration. CONCLUSIONS Our findings suggest that metformin could be a useful adjuvant agent, with the greatest benefits seen in colorectal and prostate cancer, particularly in those receiving radical radiotherapy, and randomised, controlled trials which investigate dose and duration, alongside efficacy, are advocated.

Abstract
BACKGROUND Many medications administered to patients with schizophrenia possess anticholinergic properties. When aggregated, pharmacological treatments may result in a considerable anticholinergic burden. The extent to which anticholinergic burden has a deleterious effect on cognition and impairs ability to participate in and benefit from psychosocial treatments is unknown. METHOD Seventy patients were followed for approximately 3 years. The MATRICS consensus cognitive battery (MCCB) was administered at baseline. Anticholinergic burden was measured with the Anticholinergic Cognitive Burden (ACB) scale. Ability to benefit from psychosocial programmes was measured using the DUNDRUM-3 Programme Completion Scale (D-3) at baseline and follow-up. Psychiatric symptoms were measured using the PANSS. Total antipsychotic dose was measured using chlorpromazine equivalents. Functioning was measured using the Social and Occupational Functioning Assessment Scale (SOFAS). RESULTS Mediation analysis found that the influence of anticholinergic burden on ability to participate and benefit from psychosocial programmes was completely mediated by the MCCB. For every 1-unit increase on the ACB scale, change scores for DUNDRUM-3 decreased by -0.27 points. This relationship appears specific to anticholinergic burden and not total antipsychotic dose. Moreover, mediation appears to be specific to cognition and not psychopathology. Baseline functioning also acted as mediator but only when MCCB was not controlled for. CONCLUSIONS Anticholinergic burden has a significant impact on patients' ability to participate in and benefit from psychosocial treatment programmes. Physicians need to be mindful of the cumulative effect that medications can have on patient cognition, functional capacity and ability to benefit from psychosocial treatments.

Abstract
Objectives Analysis of screening uptake usually dichotomizes women into attenders and non-attenders, though many women respond positively to some but not all invitations. This paper studies these intermittent attenders. Methods A cohort of 8,571 women invited for consecutive breast screens in the Northern Ireland Breast Screening Programme were followed in a study linking screening and census records. Multivariate logistic analysis was used to analyze the characteristics of those who attended both times (consistent), once (intermittent or ‘one-time only’), or not at all (non-attenders). Results Overall, 15.5% of women attended once and 13.4% were non-attenders. Non-attenders were characteristically disadvantaged (as measured by social renting, car access, and employment status), less likely to be married, and more likely to be healthy. One-time attenders were younger, and suffering poor health, though there was no association with either social renting or employment status. Privately rented accommodation and city living was associated with both one-time attendance and non-attendance. Conclusions One-time attenders are an important and distinct subgroup of screening invitees in this analysis. Their distinct characteristics suggest that transitory factors, such as change in marital status, ill-health, or addressing difficulties through change of residence are important. These distinct characteristics suggest the need for different approaches to increase attendance, among both intermittent attenders and those not attending at all.

Abstract
BACKGROUND The population in developed countries is ageing. Cancer is a disease of ageing, and this is likely to lead to an increase in the number of older patients diagnosed with cancer with significant implications for resource allocation and research priorities. Breast Cancer in older women presents a number of challenges. AIMS This paper describes the trends in number of new breast cancer registrations in older patients over the last 38 years. MATERIALS AND METHODS Data were extracted from the Office for National Statistics describing new registrations of breast cancer for patients aged 65 or over, from 1971 to 2009. RESULTS The number of diagnoses of breast cancer across all age groups increased from 17,694 in 1971 to 40,260 in 2009. The proportion of diagnoses of breast cancer made in women aged 65 and over increased from 42% in 1971 to 45% in 2009. The proportion of diagnoses of breast cancer made in women aged 70 and over increased from 30% in 1971 to 33% in 2009. The number of cases of breast cancer registered in patients aged 65 and over has increased from 7376 in 1971 to 17,934 in 2009. DISCUSSION The reasons for the large increases in the number of older women diagnosed with breast cancer, and older women represent an increasing proportion of those diagnosed are multi-factorial. These include the ageing of the population, obesity, alcohol consumption, use of hormone replacement therapy and reproductive factors, improved breast cancer awareness and the UK National Screening Programme. Clinician attitudes and behaviours and also cancer registries striving to increase their levels are other causes. The effective management of these women will present constraints to service delivery and should therefore influence research priorities. CONCLUSION This short communication reports on the increasing registration of breast cancer in the older age group which will present a number of challenges for the future.

Abstract
AIMS To determine the outcome and morbidity after radiotherapy for locally recurrent cervical cancer. MATERIALS AND METHODS Women who presented with locally recurrent cervical cancer after surgery alone during 1985 and 1997 were identified from the hospital database. Data were collected and analysed to include the stage at first diagnosis, staging investigations before surgery, the surgical procedure, the indication for radiotherapy, the type of radiotherapy, morbidity and survival. RESULTS In total, 130 women had radical external beam radiotherapy and/or intracavitary brachytherapy for locoregional recurrence during the defined study period. The 5-year disease-specific survival for the study population was 40.2%. Women who were treated for vault recurrence had a significantly better 5-year disease-free survival compared with women who developed nodal recurrence alone (55.4% vs 12.5%). This group of women also had a significantly slower rate of disease progression after radiotherapy than women with nodal recurrence (48.7% vs 87.5%, P=0.0001). CONCLUSION Radical radiotherapy alone is able to salvage 55% of vaginal vault recurrences after surgery for cervical cancer with minimal late toxicity. Salvage rates in women with pelvic nodal recurrences are considerably lower. Chemoradiotherapy using intensity-modulated radiotherapy to deliver an escalated radiotherapy dose needs to be pursued to improve locoregional control.

Abstract
The objective of this study was to assess treatment outcomes in a large case series of cervical cancer patients undergoing postoperative radiotherapy in a single center. Case notes of women referred to the Christie Hospital during 1985-1997 for postoperative adjuvant radiotherapy for cervical cancer were reviewed. Of 478 women eligible for analysis, 282 (58.9%) underwent radical hysterectomy and 196 (41.1%) had nonradical hysterectomy. The disease-specific 5-year survival for the study population is 70.1%, with a 5-year risk of developing any recurrence of 30.5% and a 5-year grade 3 morbidity rate of 3.9%. Survival was significantly higher, ie, 80.9% vs 62.7% (P = 0.0001) and recurrence was significantly lower, ie, 18.6% vs 38.8% (P < 0.00005) in the group of women who had adjuvant radiotherapy following a nonradical hysterectomy compared with radical surgery. Thirty percent of women having "radical" surgery had positive resection margins and required postoperative adjuvant pelvic radiotherapy. Women with node-positive disease, who received adjuvant radiotherapy, had a high rate of distant metastases. These women would receive chemoradiotherapy now as primary treatment because of the risk of developing distant metastases. If, despite staging investigations, surgery reveals node-positive disease, then these women should receive adjuvant chemoradiotherapy. Survival was better in women who had nonradical surgery due to smaller volume disease when cancers were unsuspected and hence will have been cured by surgery alone. Multidisciplinary team working, as recommended by national guidelines from 1999, should allow better patient selection for treatment.

Abstract
PURPOSE In March 2001, the National Colorectal Cancer Research Alliance (NCCRA) and OncoLink (http://www.oncolink.org) established a database to facilitate patient enrollment onto clinical trials. This study describes the population registering with the database and identifies discrepancies between individuals registering through the Internet and those registering through a telephone call center. METHODS Participants registered with the NCCRA/OncoLink database through the Internet or a telephone call center. All participants entering the database completed a questionnaire regarding basic demographics, colon cancer risk factors, and indicated how they became aware of the database. Comparisons were made between individuals registering through the Internet and those registering through the telephone call center. RESULTS A total of 2,162 participants registered during the first 16 months of the database. Most patients registered through the Internet rather than the telephone call center (88% v 12%; P < .001). More females than males registered (73% v 27%; P < .001). The majority (89%) were white. Participants registering through the Internet were younger than those registering through the call center (mean, 48.8 v 55.0 years; P < .001). There was no difference between the two groups with regard to sex or ethnicity. CONCLUSION The Internet has the potential to increase the likelihood that interested individuals find appropriate clinical trials. Some of the discrepancies that are known to exist for access to the Internet were also seen for those registering with the database through the Internet. Despite these differences, the potential to increase clinical trial enrollment with this type of Internet-based database is high.

Dental students, social policy students and learning disability: do differing attitudes exist?

Abstract
OBJECTIVES To examine the attitudes of dental students and social policy students towards learning disabilities in order to identify whether attitudinal differences exist and to suggest recommendations in the dental undergraduate curriculum commensurate with Government legislation in the United Kingdom. DESIGN A cross-sectional survey of all undergraduate dental students at Queen's University, Belfast and all undergraduate social policy students at University of Ulster. METHOD A convenience sample of all undergraduate dental and social policy students was obtained. The students completed a questionnaire to assess attitude towards learning disability. The data were analysed using Cronbach's alpha, Student's t-test and analysis of variance (one-way fixed effect model). The level of statistical significance was set at 5%. RESULTS The response rate was 83% for dental students and 97% for social policy students. Dental students had significantly lower mean scores and hence less favourable attitudes to learning disability compared with social policy students. Female dental students had significantly higher mean scores and hence more favourable attitudes to learning disability compared with male students. CONCLUSIONS The findings show that dental undergraduates compared with social policy students had less favourable attitudes towards those with learning disability. Dental students should receive training in learning disability and undergraduate programmes should be conceptualised as a spiral curriculum. It is proposed that social policy theory should be introduced into undergraduate dental curricula, that early exposure to learning disability in a community setting should be incorporated into the first undergraduate years and in later undergraduate clinical years students should treat patients with learning disability in order to promote experiential learning and reflective practice.
