Review
Gastro-oesophageal reflux is associated with a wide range of respiratory disorders, including asthma, isolated chronic cough, idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease and cystic fibrosis. Reflux can be substantial and reach the proximal margins of the oesophagus in some individuals with specific pulmonary diseases, suggesting that this association is more than a coincidence. Proximal oesophageal reflux in particular has led to concern that microaspiration might have an important, possibly even causal, role in respiratory disease. Interestingly, reflux is not always accompanied by typical reflux symptoms, such as heartburn and/or regurgitation, leading many clinicians to empirically treat for possible gastro-oesophageal reflux. Indeed, costs associated with use of acid suppressants in pulmonary disease far outweigh those in typical GERD, despite little evidence of therapeutic benefit in clinical trials. This Review comprehensively examines the possible mechanisms that might link pulmonary disease and oesophageal reflux, highlighting the gaps in current knowledge and limitations of previous research, and helping to shed light on the frequent failure of antireflux treatments in pulmonary disease.

Review
(Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection. There is no ideal treatment for Hp. Hp infection is not cured by a single antibiotic, and sometimes, a combined treatment with three or more antibiotics is ineffective. Atrophic gastritis (AG) is a chronic disease whose main features are atrophy and/or intestinal metaplasia of the gastric glands, which arise from long-standing Hp infection. AG is reportedly linked to an increased risk for gastric cancer, particularly when extensive intestinal metaplasia is present. Active or past Hp infection may be detected by conventional methods in about two-thirds of AG patients. By immunoblotting of sera against Hp whole-cell protein lysates, a previous exposure to Hp infection is detected in all AG patients. According to guidelines, AG patients with Hp positivity should receive eradication treatment. The goals of treatment are as follows: (1) Cure of infection, resolution of inflammation and normalization of gastric functions; (2) possible reversal of atrophic and metaplastic changes of the gastric mucosa; and (3) prevention of gastric cancer. An ideal antibiotic regimen for Hp should achieve eradication rates of approximately 90%, and complex multidrug regimens are required to reach this goal. Amongst the factors associated with treatment failure are high bacterial load, high gastric acidity, Hp strain, smoking, low compliance, overweight, and increasing antibiotic resistance. AG, when involving the corporal mucosa, is linked to reduced gastric acid secretion. At a non-acidic intra-gastric pH, the efficacy of the common treatment regimens combining proton pump inhibitors with one or more antibiotics may not be the same as that observed in patients with Hp gastritis in an acid-producing stomach. Although the efficacy of these therapeutic regimens has been thoroughly tested in subjects with Hp infection, there is a paucity of evidence in the subgroup of patients with AG. Bismuth-based therapy may be an attractive treatment in the specific setting of AG, and specific studies on the efficacy of bismuth-based therapies are needed in patients with AG.

Review
Gastroesophageal reflux disease (GERD) is the most common acid-related disorder encountered during clinical practice in Pakistan and is associated with significant impairment of health-related quality of life. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Pakistani accepted directive by the standards of evidence-based medicine is still lacking. Our aim was to create an understanding of the natural history and presentations of reflux disease; evaluating possible treatment options available for the patients with complex and uncomplicated reflux ailments with the development of current and up to date evidence based endorsement, relevant to the needs of Pakistani health care providers in order to treat oesophageal manifestations of GERD. In order to make such guidelines, a comprehensive literature search was conducted with pertinent evidence reviewed, and quality of relevant data assessed. The resultant conclusions were based on the best available evidence and expert opinion of the authors of technical review panel.

Meta-Analysis Review
BACKGROUND
Heartburn is one of the most common gastrointestinal symptoms in pregnant women. It can occur in all trimesters of pregnancy. The symptoms of heartburn in pregnancy may be frequent, severe and distressing, but serious complications are rare. Many interventions have been used for the treatment of heartburn in pregnancy. These interventions include advice on diet, lifestyle modification and medications. However, there has been no evidence-based recommendation for the treatment of heartburn in pregnancy.
OBJECTIVES
To assess the effects of interventions for relieving heartburn in pregnancy.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2015), ClinicalTrials.gov (2 March 2015), Asian & Oceanic Congress of Obstetrics & Gynaecology (AOCOG) conference proceedings (20-23 October 2013, Centara Grand & Bangkok Convention Centre, Bangkok, Thailand), and reference lists of retrieved studies.
SELECTION CRITERIA
Randomised controlled trials (RCTs) and quasi-RCTS of interventions for heartburn in pregnancy compared with another intervention, or placebo, or no intervention. Cluster-RCTs would have been eligible for inclusion but none were identified. We excluded studies available as abstracts only and those using a cross-over design.Interventions could include advice on diet, lifestyle modification and medications (such as antacids, sucralfate, histamine 2-receptor antagonists, promotility drugs and proton pump inhibitors (PPIs)).
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy.
MAIN RESULTS
We included nine RCTs involving 725 women. However, five trials did not contribute data. Four trials involving 358 women contributed data. Trials were generally at mixed risk of bias.We only identified data for three comparisons: pharmaceutical treatment versus placebo or no treatment; acupuncture versus no treatment and pharmacological intervention versus advice on dietary and lifestyle changes. Pharmaceutical treatment compared with placebo or no treatmentTwo trials evaluated any pharmaceutical treatment compared with placebo or no treatment. One trial examined a treatment rarely used nowadays (intramuscular prostigmine 0.5 mg versus placebo). One trial evaluated the effect of magnesium and aluminium hydroxide plus simethicone liquid and tablet compared with placebo. For the primary outcome of this review (relief of heartburn), women who received pharmaceutical treatment reported complete heartburn relief more often than women receiving no treatment or placebo (risk ratio (RR) 1.85, 95% confidence interval (CI) 1.36 to 2.50 in two RCTs of 256 women, I(2) = 0%, moderate-quality evidence). Data on partial relief of heartburn were heterogenous and showed no clear difference (average RR 1.35, 95% CI 0.38 to 4.76 in two RCTs of 256 women, very low-quality evidence). In terms of secondary outcomes, there was no clear difference in the rate of side effects between the pharmaceutical treatment group and the placebo/no treatment group (RR 0.63, 95% CI 0.21 to 1.89 in two RCTs of 256 women, very low-quality evidence). Pharmacological intervention versus advice on dietary and lifestyle choicesOne study compared 1 g of sucralfate with advice on dietary and lifestyle choices in treating heartburn. More women in the sucralfate group experienced complete relief of heartburn compared to women who received advice on diet and lifestyle choices (RR 2.41, 95% CI 1.42 to 4.07; participants = 65; studies = one). The only secondary outcome of interest addressed by this trial was side effects. The evidence was not clear on intervention side effects rate between the two groups (RR 1.74, 95% CI 0.07 to 41.21; participants = 66; studies = one). There was only one instance of side effects in the pharmacological group. Acupuncture compared with no treatmentOne trial evaluated acupuncture compared with no treatment but did not report data relating to this review's primary outcome (relief of heartburn). In terms of secondary outcomes, there was no difference in the rate of side effects between women who had acupuncture and women who had no treatment (RR 2.43, 95% CI 0.11 to 55.89 in one RCT of 36 women). With regard to quality of life, women who had acupuncture reported improved ability to sleep (RR 2.80, 95% CI 1.14 to 6.86) and eat (RR 2.40, 95% CI 1.11 to 5.18 in one RCT of 36 women).The following secondary outcomes were not reported upon in any of the trials included in the review: miscarriage, preterm labour, maternal satisfaction, fetal anomalies, intrauterine growth restriction, low birthweight.
AUTHORS' CONCLUSIONS
There are no large-scale RCTs to assess heartburn relief in pregnancy. This review of nine small studies (which involved data from only four small studies) indicates that there are limited data suggesting that heartburn in pregnancy could be completely relieved by pharmaceutical treatment. Three outcomes were assessed and assigned a quality rating using the GRADE methods. Evidence from two trials for the outcome of complete relief of heartburn was assessed as of moderate quality. Evidence for the outcomes of partial heartburn relief and side effects was graded to be of very low quality. Downgrading decisions were based in part on the small size of the trials and on heterogenous and imprecise results.There are insufficient data to assess acupuncture versus no treatment and no data to assess other comparisons (miscarriage, preterm labour, maternal satisfaction, fetal anomalies, intrauterine growth restriction, low birthweight).Further RCTs are needed to fully evaluate the effectiveness of interventions for heartburn in pregnancy. Future research should also address other medications such as histamine 2-receptor antagonists, promotility drugs, proton pump inhibitors, and a raft-forming alginate reflux suppressant in treatment of heartburn in pregnancy. More research is needed on acupuncture and other complimentary therapies as treatments for heartburn in pregnancy. Future research should also evaluate any adverse outcomes, maternal satisfaction with treatment and measure pregnant women's quality of life in relation to the intervention.

Review
As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in Japan concerning the epidemiology, pathophysiology, treatment, and Barrett's esophagus during this period. By incorporating the contents of these reports, the guidelines were completely revised, and a new edition was published in October 2015. The revised edition consists of eight items: epidemiology, pathophysiology, diagnosis, internal treatment, surgical treatment, esophagitis after surgery of the upper gastrointestinal tract, extraesophageal symptoms, and Barrett's esophagus. This paper summarizes these guidelines, particularly the parts related to the treatment for GERD. In the present revision, aggressive proton pump inhibitor (PPI) maintenance therapy is recommended for severe erosive GERD, and on-demand therapy or continuous maintenance therapy is recommended for mild erosive GERD or PPI-responsive non-erosive GERD. Moreover, PPI-resistant GERD (insufficient symptomatic improvement and/or esophageal mucosal break persisting despite the administration of PPI at a standard dose for 8 weeks) is defined, and a standard-dose PPI twice a day, change in PPI, change in the PPI timing of dosing, addition of a prokinetic drug, addition of rikkunshito (traditional Japanese herbal medicine), and addition of histamine H2-receptor antagonist are recommended for its treatment. If no improvement is observed even after these treatments, pathophysiological evaluation with esophageal impedance-pH monitoring or esophageal manometry at an expert facility for diseases of the esophagus is recommended.

Review
Gut microbial communities are capable of enzymatically transforming pharmaceutical compounds into active, inactive, and toxic metabolites, thus potentially affecting the pharmacokinetics and bioavailability of orally administered medications. Our understanding of the impact and clinical relevance of how gut microbial communities can directly and indirectly affect drug metabolism and, ultimately, clinical outcomes, is limited. Interindividual variability of gut microbial composition may partially explain differences observed in drug efficacy and toxicity in certain patient populations. This review provides an overview of how gut microbial communities can potentially contribute to individual drug response. This review focuses on the current landscape of clinical and preclinical research that defines the microbiome contribution on medication response with the goal of improving medication efficacy and decreasing medication toxicity.

Alternative and rapid microbiological methods can be effective replacements for more traditional plating approaches for ensuring quality and safety in the pharmaceutical industry. This article compares the efficacy of the Soleris automated method and the traditional plate-count method for the quantitative detection of yeasts and molds at three different microbial bioburden levels. Validation testing was carried out using an antacid oral suspension (aluminum hydroxide 4% + magnesium hydroxide 4% + simethicone 0.4%). Equivalence of data between detection time and colony-forming units was established for both the alternative and the conventional methodologies. Using probability of detection, linear Poisson regression, Fisher's test, and multifactorial analysis of variance (ANOVA), all results from the rapid method were shown to be in statistical agreement with the those of the reference plating procedures. The limits of detection and quantification were statistically similar for both methods (Fisher's exact test, > 0.05), showing that the alternative method is in performance to the reference method. Essential validation parameters such as precision (standard deviation <5, coefficient of variance <35%), accuracy (>70%), linearity (R >0.9025), ruggedness (ANOVA, < 0.05), operative range, and specificity were determined. It was shown that all the test results obtained using the alternative method were in statistical agreement with the those of the standard plate-count method. Thus, this new technology was found to meet all the validation criteria needed to be considered as an alternative method for yeast and mold quantification in the antacid oral suspension tested. However, taking into account that the present validation was carried out utilizing and as suitable models for yeasts and molds and with an antacid oral suspension as a pharmaceutical matrix, further investigation will be required to qualify Soleris technology for other environmental isolates and recovery of these isolates from production batches.
