Health Is Power, and Health Is Wealth: Understanding the Motivators and Barriers of African American/Black Male Immigrants With Gastrointestinal Conditions.

The digestive health of African American/Black male immigrants in the United States has not been previously studied. Much of what is known about gastrointestinal (GI) concerns in this population is based on studies conducted on the overall Black American population. The purpose of this narrative study was to understand how African American/Black male immigrants with GI concerns navigated their GI condition. Fifteen African American/Black male immigrants from various cities in the United States participated in two remote focus groups to discover what motivates them to take control of their illness. Narrative analysis was used to analyze the qualitative data. Most men, 47% (n = 7), did not have health insurance, and 67% (n = 10) reported their income was less than US$52,000. The themes identified were: (1) lack of knowledge of GI, (2) denial of initial diagnosis, (3) self-discipline, (4) positive provider interactions, (5) health as a priority, and (6) advice to other African American/Black male immigrants experiencing GI. A strengths-based approach is necessary for describing the health-seeking behaviors among African American/Black male immigrants.

Medicinal plants used to treat "African" diseases by the local communities of Bwambara sub-county in Rukungiri District, Western Uganda.

ETHNOPHARMACOLOGICAL RELEVANCE: In Africa, traditional medicine encompasses a diverse range of practices, including herbalism and spiritualism, where some diseases are believed to be "African" since they can only be traditionally treated. Indigenous knowledge on the management of "African" diseases using medicinal plants is still handed down orally from generation to generation by tribal societies of tropical Africa, and with the rapid westernization of these societies there is a pressing need to record local knowledge before it is lost forever. AIM: This study documented medicinal plant species associated with the management of "African" diseases by the local communities of Bwambara sub-county in Rukungiri district, Western Uganda. METHODS: A cross-sectional study was conducted using semi-structured questionnaires and interviews. The data collected included names of plant species, plant parts used, diseases treated, methods of preparation, and mode of administration of the herbal remedies. A total of 196 informants participated in the study. Data were analyzed and presented using descriptive statistics and the Informant consensus factor. RESULTS: We documented 67 medicinal plant species distributed over 27 families and 62 genera. The most commonly reported species belong to Asteraceae family. The most frequently used medicinal species were Chenopodium opulifolium (27), Sesbania sesban (26), Thevetia peruviana (25), Leonotis nepetifolia (23), Momordica foetida (23), Euphorbia hirta (21) and Cassia mimosoides (20). Leaves were the most commonly used plants parts and decoctions were the main method of preparation. Water was the main medium used for the preparation of the remedies which were administered orally while petroleum jelly was the main medium for those which were used as ointments. The medicinal plant species reported are used to treat 39 conditions which were clustered into 10 International Classification of Primary Care (ICPC) disease categories. There is a high degree of consensus among the informants on which medicinal plant species they use for different diseases especially disorders in the following categories: neurological (FIC = 0.90), general and unspecified (FIC = 0.87), digestive (FIC = 0.86) and female genital (FIC = 0.82). CONCLUSION: Local communities of Bwambara sub-county in Rukungiri district, Western Uganda use a rich diversity of medicinal plant species in the management of various "African" diseases. Therefore, collaboration between users of medicinal plants and scientists is paramount, to help in the discovery of new drugs based on indigenous knowledge.

Are Anxious and Depressive Symptoms Associated with Gastrointestinal Symptoms in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)?

Psychological distress is common among non-Hispanic/Latino adults with gastrointestinal (GI) symptoms. Heartburn and acid regurgitation symptom prevalence, and their relationship with anxious and depressive symptoms, was examined in 16,415 Hispanic Community Health Study/Study of Latinos participants aged 18-74 from 4 US cities (Bronx, NY; Chicago, IL; Miami, FL; San Diego, CA). Complex survey logistic regression models were used to test relations between GI, anxious, and depressive symptoms. 10.1% (95% confidence interval [CI] = 9.4, 10.8) and 8.9% (95% CI = 8.3, 9.5) of the overall sample (estimates are weighted and adjusted for age and body mass index) respectively self-reported heartburn and acid regurgitation at least several times/week within the past year. Adults who reported GI symptoms several times/week or more also self-reported higher psychological distress compared to adults who reported GI symptoms less frequently. For one standard deviation higher in anxious symptoms (5.6 units), GI prevalence odds were respectively 1.14 (95% CI = 1.10, 1.17) and 1.14 (95% CI = 1.09, 1.18) for heartburn and acid regurgitation. GI prevalence odds (heartburn = 1.14, 95% CI = 1.11, 1.18; acid regurgitation = 1.15, 95% CI = 1.10, 1.18) were similar for one standard deviation higher in depressive symptoms (5.9 units). Demographic, health, and clinical characteristics did not significantly attenuate relationships between GI and psychological distress symptoms. Psychological distress is related to GI symptoms in US Hispanics/Latinos.

Gastric microbiota and Helicobacter pylori in Indonesian population.

BACKGROUND: The profile of gastric mucosal microbiota has not yet been described in the Indonesian population where the prevalence of Helicobacter pylori is low. METHODS: This is a cross-sectional study analyzing 16S rRNA of 137 gastric biopsy specimens. We analyzed the association between gastric microbiota, H. pylori infection, and gastric mucosal damage. RESULT: Among 137 analyzed samples, 27 were H. pylori-positive and 110 were H. pylori -negative based on culture, histology, and 16S rRNA gene analysis. Significantly lower α-diversity parameters, including Pielou's index, was observed in H. pylori-infected individuals compared with noninfected individuals (all P < .001). Among H. pylori-negative individuals, the permutational analysis of variance of Bray-Curtis dissimilarity distances showed a significant association with different ethnicities, suggesting some ethnic groups had specific microbiota profiles based on the presence of different operational taxonomic units. The linear discriminant analysis effect size (LEfSe) of the H. pylori-negative group showed significant associations between the presence of Micrococcus luteus and Sphingomonas yabuuchiae with Timor and Papuan ethnicities, respectively. The presence of Bulledia sp and Atopobium sp was associated with the Javanese ethnicity. We observed lower α-diversity scores in individuals with gastric mucosal damage and profiles with high abundances of Paludibacter sp and Dialister sp based on LEfSe analysis. CONCLUSION: Our findings suggest the presence of H. pylori is more correlated with a distinct microbiome profile than ethnic precedence.

Medicinal plants for gastrointestinal diseases among the Kuki-Chin ethnolinguistic groups across Bangladesh, India, and Myanmar: A comparative and network analysis study.

ETHNOPHARMACOLOGICAL RELEVANCE: The Kuki-Chin is a composite ethnolinguistic group made up of many distinct groups and subgroups that are linked by a common history, culture, and population distribution in the Kuki-Chin region, shared geopolitically by Bangladesh, India, and Myanmar. This region is shown to be in a hotspot of digestive disease activity based on official reports and in concordance with data from related ethnopharmacological field surveys. Our work provides a comparative analysis of medicinal plant knowledge for the treatment of gastrointestinal diseases (GAS-Ds) among the Kuki-Chin ethnic groups found across the three countries. AIM OF THE STUDY: The objectives were (1) to identify the medicinal plants and herbal therapies for the treatment of GAS-Ds reported in related Kuki-Chin ethnobotanical publications, (2) to find the similarities and differences in medicinal plant knowledge among the country-affiliated groups by comparing plant and disease information, and (3) to determine significant plant taxa and their pattern(s) of use as digestive disease herbal remedies by analyzing disease-plant networks. MATERIALS AND METHODS: Secondary data were gathered from 34 related studies through internet search of ethnobotanical information from field studies published in journals, reports, books, and dissertations/theses. These data represented 22 Kuki-Chin ethnolinguistic groups inhabiting 23 districts across six states comprising the Kuki-Chin region: the Chittagong Division (Bangladesh); Mizoram, Assam, Manipur, and Tripura States (India); and Chin State (Myanmar). Scientific names of plants and digestive diseases collated from secondary sources were validated and standardized following the Plant List and the International Classification of Primary Care Second Edition, respectively. RESULTS AND DISCUSSION: A total of 482 species in 330 genera and 118 families of vascular plants were recorded for the treatment of 29 standardized GAS-Ds. On the basis of the number of use-reports, regional native species Phyllanthus emblica, Centella asiatica, and Aegle marmelos, as well as the non-natives Carica papaya, Portulaca oleracea, and Psidium guajava were found to be the most preferred. Comparative analysis of medicinal species showed that groups in India revealed the highest number of medicinal plant taxa, followed by those in Bangladesh and Myanmar. The most prevalent GAS-Ds were shown to be abdominal pain epigastric, gastroenteritis presumed infections, and diarrhoea, as supported by the number of use-reports and medicinal taxa used for their treatment, and their informant consensus factor values. Analyses of disease-plant networks graphically showed both GAS-Ds distribution patterns in the region and potential medicinal plant (group) candidates for further studies. CONCLUSION: Overall, this study revealed an astonishingly rich diversity of medicinal plants used to treat digestive diseases among the Kuki-Chin. A comparative analysis showed variations and remarkable distinctions in medicinal plant knowledge among country-affiliated groups, as likely influenced by external sociocultural factors and geopolitical barriers, as well as the availability of ethnobotanical data. The use of network analysis reflected not only shared common affinities and patterns of plant use based on the taxonomic composition and species selection, but also disease prevalence and distribution patterns. The information found here can hopefully spur interest among future researchers and policy makers to better improve both the (ethno) medicinal research capacity and healthcare system in the region.

Acute gastrointestinal illness in an African Indigenous population: the lived experience of Uganda's Batwa.

INTRODUCTION: Indigenous populations in low-income regions are often the most acutely affected by social gradients that impact health, including high burdens of infectious disease. Using a mixed methods approach, this study characterized the lived experience of acute gastrointestinal illness (AGI) in an Indigenous Batwa population in south-western Uganda. METHODS: Quantitative data analyses were conducted on data from three cross-sectional census surveys of Batwa conducted in January 2013 (n=583), January 2014 (n=569) and April 2014 (n=540). Using a 14-day recall period, cases of AGI were defined as three or more loose stools or any vomiting in a 24-hour period. These analyses were supplemented by qualitative data from key informant interviews (n=11 interviews) and Batwa focus group discussions (n=61 participants). RESULTS: From the surveys, episodes of diarrhea and episodes of vomiting lasted on average 3.6 (95%CI 2.3-4.3) and 3.0 (95%CI 2.1-3.9) days, and individuals experienced an average of 4.3 (95%CI 3.9-4.8) and 2.6 (95%CI 2.1-3.1) loose stools and vomiting episodes in 24 hours. Focus group participants and key informants indicated that episodes of AGI for Batwa were not limited to symptom-based consequences for the individual, but also had economic, social and nutritional impacts. CONCLUSION: Despite efforts to increase health literacy in disease transmission dynamics, risks and prevention measures, the perceived barriers and a lack of benefits still largely underscored adopting positive AGI prevention behaviors. This study moved beyond surveillance and provided information on the broader community-level burden of AGI and highlighted the current challenges and opportunities for improved uptake of AGI prevention measures for the Batwa.

What is the qualitative evidence concerning the risks, diagnosis, management and consequences of gastrointestinal infections in the community in the United Kingdom? A systematic review and meta-ethnography.

BACKGROUND: Gastrointestinal (GI) infections cause a significant public health burden worldwide and in the UK with evidence pointing to socio-economic inequalities, particularly among children. Qualitative studies can help us understand why inequalities occur and contribute to developing more effective interventions. This study had two aims: 1. Conduct a systematic review to determine the extent and nature of UK qualitative evidence on gastrointestinal infections; 2. Use meta-ethnography to examine the influences of the differing social contexts in which people live. METHODS: MEDLINE, Scopus, Web of science, CINAHL and JSTOR were searched for UK qualitative studies engaging with the risk, diagnosis, management or consequences of gastrointestinal infections from 1980 to July 2019. Five reviewers were involved in applying inclusion and exclusion criteria, extracting and synthesising data (PROSPERO CRD 42017055157). RESULTS: Searches identified 4080 studies, 18 met the inclusion criteria. The majority (n = 16) contained data relating to the risk of gastrointestinal infection and these made up the main synthesis. The tenets of meta-ethnography were used to glean new understandings of the role of social and environmental contexts in shaping the risk of gastrointestinal infection, specifically with respect to foodborne GI illness. Three main explanations concerning risk emerged from the data: explanations of risk in the community were underpinned by understandings of 'bugs', dirt and where food comes from; risks were negotiated in households alongside diverse processes of decision making around food; and resources available to households shaped food practices. CONCLUSION: This systematic review highlights the scarcity of UK qualitative evidence examining gastrointestinal infections. Apart from risk, questions around diagnosis, management and consequences of illness were largely untouched. No studies investigated patterning by socio-economic status. Nevertheless, the meta-ethnography yielded wider contextual theories and explanations as to why people might not follow food hygiene guidance, giving pointers to the types of qualitative enquiry needed to develop more effective interventions.

Burden and Cost of Gastrointestinal, Liver, and Pancreatic Diseases in the United States: Update 2018.

BACKGROUND & AIMS: Estimates of disease burden can inform national health priorities for research, clinical care, and policy. We aimed to estimate health care use and spending among gastrointestinal (GI) (including luminal, liver, and pancreatic) diseases in the United States. METHODS: We estimated health care use and spending based on the most currently available administrative claims from commercial and Medicare Supplemental plans, data from the GI Quality Improvement Consortium Registry, and national databases. RESULTS: In 2015, annual health care expenditures for gastrointestinal diseases totaled $135.9 billion. Hepatitis ($23.3 billion), esophageal disorders ($18.1 billion), biliary tract disease ($10.3 billion), abdominal pain ($10.2 billion), and inflammatory bowel disease ($7.2 billion) were the most expensive. Yearly, there were more than 54.4 million ambulatory visits with a primary diagnosis for a GI disease, 3.0 million hospital admissions, and 540,500 all-cause 30-day readmissions. There were 266,600 new cases of GI cancers diagnosed and 144,300 cancer deaths. Each year, there were 97,700 deaths from non-malignant GI diseases. An estimated 11.0 million colonoscopies, 6.1 million upper endoscopies, 313,000 flexible sigmoidoscopies, 178,400 upper endoscopic ultrasound examinations, and 169,500 endoscopic retrograde cholangiopancreatography procedures were performed annually. Among average-risk persons aged 50-75 years who underwent colonoscopy, 34.6% had 1 or more adenomatous polyps, 4.7% had 1 or more advanced adenomatous polyps, and 5.7% had 1 or more serrated polyps removed. CONCLUSIONS: GI diseases contribute substantially to health care use in the United States. Total expenditures for GI diseases are $135.9 billion annually-greater than for other common diseases. Expenditures are likely to continue increasing.

A cross-sectional investigation of the health needs of asylum seekers in a refugee clinic in Germany.

BACKGROUND: Over one million asylum seekers were registered in Germany in 2016, most from Syria and Afghanistan. The Refugee Convention guarantees access to healthcare, however delivery mechanisms remain heterogeneous. There is an urgent need for more data describing the health conditions of asylum seekers to guide best practices for healthcare delivery. In this study, we describe the state of health of asylum seekers presenting to a multi-specialty primary care refugee clinic. METHODS: Demographic and medical diagnosis data were extracted from the electronic medical records of patients seen at the ambulatory refugee clinic in Dresden, Germany between 15 September 2015 and 31 December 2016. Data were de-identified and analyzed using Stata version 14.0. RESULTS: Two-thousand-seven-hundred and fifty-three individual patients were seen in the clinic. Of these, 2232 (81.1%) were insured by the state indicating arrival within the last 3 months. The median age was 25, interquartile range 16-34. Only 786 (28.6%) were female, while 1967 (71.5%) were male. The most frequent diagnoses were respiratory (17.4%), followed by miscellaneous symptoms and otherwise not classified ailments (R series, 14.1%), infection (10.8%), musculoskeletal or connective tissue (9.3%), gastrointestinal (6.8%), injury (5.9%), and mental or behavioral (5.1%) categories. CONCLUSIONS: This study illustrates the diverse medical conditions that affect the asylum seeker population. Asylum seekers in our study group did not have a high burden of communicable diseases, however several warranted additional screening and treatment, including for tuberculosis and scabies. Respiratory illnesses were more common amongst newly arrived refugees. Trauma-related mental health disorders comprised half of mental health diagnoses.

Housing conditions associated with recurrent gastrointestinal infection in urban Aboriginal children in NSW, Australia: findings from SEARCH.

OBJECTIVE: To examine the associations between housing and gastrointestinal infection in Aboriginal children in urban New South Wales. METHODS: A total of 1,398 Aboriginal children were recruited through four Aboriginal Community Controlled Health Services. Multilevel regression modelling of survey data estimated associations between housing conditions and recurrent gastrointestinal infection, adjusting for sociodemographic and health factors. RESULTS: Of the sample, 157 children (11%) had recurrent gastrointestinal infection ever and 37 (2.7%) required treatment for recurrent gastrointestinal infection in the past month. Children in homes with 3+ housing problems were 2.51 (95% CrI 1.10, 2.49) times as likely to have recurrent gastrointestinal infection ever and 6.79 (95% CrI 2.11, 30.17) times as likely to have received recent treatment for it (versus 0-2 problems). For every additional housing problem, the prevalence of recurrent gastrointestinal infection ever increased by a factor of 1.28 (95% CrI 1.14, 1.47) and the prevalence of receiving treatment for gastrointestinal infection in the past month increased by a factor of 1.64 (95% CrI 1.20, 2.48). CONCLUSIONS: Housing problems were independently associated with recurrent gastrointestinal infection in a dose-dependent manner. Implications for public health: The role of housing as a potential determinant of health in urban Aboriginal children merits further attention in research and policy settings.

Clinical and economic implications of upper gastrointestinal adverse events in Asian rheumatological patients on long-term non-steroidal anti-inflammatory drugs.

AIM: To determine the incidence and direct costs of NSAID-induced upper GI adverse events in Malaysian rheumatology patients. METHODS: A retrospective, multi-centre, cohort study of rheumatology patients on long-term NSAIDs was conducted. Clinical data of patients treated between 2010 and 2013 were collected for a 24-month follow-up period. The costs of managing upper GI adverse events were based on patient level resource use data. RESULTS: Six hundred and thirty-four patients met the inclusion criteria: mean age 53.4 years, 89.9% female, diagnosis of rheumatoid arthritis (RA; 59.3%), osteoarthritis (OA; 10.3%) and both RA and OA (30.3%). Three hundred and seventy-one (58.5%) patients were prescribed non-selective NSAIDs and 263 (41.5%) had cyclo-oxygenase-2 inhibitors. Eighty-four upper GI adverse events occurred, translating into a risk of 13.2% and an incidence rate of 66.2 per 1000 person-years. GI adverse events comprised: dyspepsia n = 78 (12.3%), peptic ulcer disease (PUD) n = 5 (0.79%) and upper GI bleeding (UGIB) n = 1 (0.16%). The total direct healthcare cost of managing adverse events was Malaysian Ringgit (MR) 37 352 (US dollars [USD] 11 419) with a mean cost of MR 446.81 ± 534.56 (USD 136.60 ± 163.42) per patient, consisting mainly of GI pharmacotherapy (33.8%), oesophagoduodenoscopies (23.1%) and outpatient clinic visits (18.2%). Mean cost per patient by GI events were: dyspepsia, MR 408.98 ± 513.29 (USD125.03 ± 156.92); PUD, MR 805.93 ± 578.80 (USD 246.39 ± 176.95); UGIB, MR 1601.94 (USD 489.74, n = 1). CONCLUSION: The economic burden of GI adverse events due to long-term NSAIDs use in Malaysian patients with chronic rheumatic diseases is modest.

Psychological factors influence the overlap syndrome in functional gastrointestinal disorders (FGIDs) among middle-aged women in South Korea.

This study investigated the psychological factors related to the overlap syndrome, i.e., multiple gastrointestinal conditions that are part of functional gastrointestinal disorders (FGIDs) in the same individual and potentially related to quality of life (QOL) among women aged 45-60 years (n = 627) in South Korea. The study was undertaken between July 2014 and March 2015. Depressive and anxiety symptoms were ascertained using the Center for Epidemiologic Studies Depression scale (CES-D) and the Beck Anxiety Inventory (BAI), respectively. Negative cognition and the cognitive triad were identified using the Automatic Thoughts Questionnaire-Negative (ATQ-N) and the Cognitive Triad Inventory (CTI), respectively. Resilience and QOL were assessed using the Connor-Davidson Resilience Scale (CD-RISC) and World Health Organization Quality of Life scale abbreviated version (WHOQOL-BREF). Women with the overlap syndrome had the highest CES-D (mean = 16.66 ± 11.79, p < .001), BAI (mean = 17.46 ± 12.67, p < .001), and ATQ-N scores (mean = 53.61 ± 20.88, p < .001), followed by women with gastrointestinal disorders but without the overlap syndrome and healthy controls. Healthy controls had the highest WHOQOL-BREF score (mean = 77.69 ± 12.53, p < .001). After stepwise selection, the final model explained 61.8 percent of the variance in QOL. Thus, depressive symptoms, anxiety, negative cognition, cognitive triad, and resilience were significantly related to QOL in women with the overlap syndrome.

Efficacy and safety of mycophenolate mofetil in patients with IgA nephropathy: an update meta-analysis.

BACKGROUND: The application of mycophenolate mofetil (MMF) in treating patients with immunoglobulin A nephropathy (IgAN) remains uncertain. This update meta-analysis was performed to re-evaluate the therapeutic potential of MMF in IgAN. METHODS: Articles were obtained by searching the electronic databases without language restriction. Randomized controlled trials studying the role of MMF in treating IgAN were collected. The quality of included studies was critically evaluated. Data analyses were performed by using RevMan 5.3 software. RESULTS: A total of 297 articles were screened and eight articles were finally included. Among the eight randomized controlled trials, five and three were high quality and low quality, respectively. Both fixed-effect and random-effect model were used. Pooled results by combining all the eight studies suggested that IgAN patients in MMF group had a higher remission rate than that in control group. Compared to placebo or corticosteroid monotherapy, MMF monotherapy exerted a higher remission rate and side effect rate in both main analysis and subgroup analysis by human race. Compared to corticosteroid plus other immunosuppressive agent therapy, corticosteroid plus MMF therapy had a higher remission rate, lower serum creatinine doubling rate, progression to end-stage renal disease rate and side effects rate. Subgroup analysis by therapeutic regimen further confirmed these results between corticosteroid plus MMF therapy and corticosteroid plus cyclophosphamide therapy. Funnel-plot displayed a symmetrical figure, indicating no publication bias existed. CONCLUSIONS: MMF has the potential in treatment of IgAN, especially for Asians. The evidence currently available shows that MMF monotherapy has a more efficacy but higher side effects when compared to placebo or corticosteroid monotherapy in treatment of Asians with IgAN. While MMF combined with corticosteroid regimen has a more efficacy and lower side effects when compared with corticosteroid plus cyclophosphamide regimen.

European Society for Paediatric Gastroenterology, Hepatology and Nutrition Guidelines for the Evaluation and Treatment of Gastrointestinal and Nutritional Complications in Children With Neurological Impairment

OBJECTIVES: Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment. METHODS: Thirty-one clinical questions addressing the diagnosis, treatment, and prognosis of common gastrointestinal and nutritional problems in neurological impaired children were formulated. Questions aimed to assess the nutritional management including nutritional status, identifying undernutrition, monitoring nutritional status, and defining nutritional requirements; to classify gastrointestinal issues including oropharyngeal dysfunctions, motor and sensory function, gastroesophageal reflux disease, and constipation; to evaluate the indications for nutritional rehabilitation including enteral feeding and percutaneous gastrostomy/jejunostomy; to define indications for surgical interventions (eg, Nissen Fundoplication, esophagogastric disconnection); and finally to consider ethical issues related to digestive and nutritional problems in the severely neurologically impaired children. A systematic literature search was performed from 1980 to October 2015 using MEDLINE. The approach of the Grading of Recommendations Assessment, Development, and Evaluation was applied to evaluate the outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation using the nominal voting technique. Expert opinion was applied to support the recommendations where no randomized controlled trials were available

Age-related common miRNA polymorphism associated with severe toxicity in lung cancer patients treated with platinum-based chemotherapy.

Platinum-based chemotherapy toxicity severely impedes successful treatment in lung cancer patients. MicroRNAs (miRs) have a significant impact on the occurrence and survival rate of lung cancer. The purpose of this study was to investigate the association between common miRNA variants and platinum-based chemotherapy toxicity in lung cancer patients. A total of eight functional single nucleotide polymorphisms (SNPs) of miRNA were genotyped in 408 lung cancer patients by MALDI-TOF mass spectrometry. All the patients were histologically confirmed as lung cancer, and were treated with platinum-based chemotherapy for at least two cycles. It was found that the polymorphism rs2042553 of miR-5197 had a significant association with overall severe toxicity in both additive (P=.031, odds ratio [OR]=1.41, 95% confidence interval [CI] 1.03-1.93) and dominant (P=.009, OR=1.80, 95% CI 1.16-2.80) models. MiR-605 rs2043556 was significantly related to severe hepatotoxicity in dominant model (P=.022, OR=2.51, 95% CI 1.12-4.14). In addition, rs2910164 of miR-146a had marginal statistical effect on severe hepatotoxicity in additive model (P=.054). The subgroup analyses showed that miR-27a rs895819 was related to gastrointestinal toxicity in age >56 years old, smoking and non-smoking patients. Taken together, our results revealed that polymorphisms of miR-5197, miR-605, miR-146a, and miR-27a contributed to the chemotherapy toxicity of lung cancer, which may serve as a predictive tool for toxicity evaluation of platinum-based chemotherapy in lung cancer patients.

Racial Variation in Patient-Reported Outcomes Following Treatment for Localized Prostate Cancer: Results from the CEASAR Study.

BACKGROUND: Relatively little is known about the relationship between race/ethnicity and patient-reported outcomes after contemporary treatments for localized prostate cancer. OBJECTIVE: To test the hypothesis that treatment-related changes in urinary, bowel, sexual, and hormonal function vary by race/ethnicity. DESIGN, SETTING, AND PARTICIPANTS: The Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) study is a prospective, population-based, observational study that enrolled 3708 men diagnosed with localized prostate cancer in 2011-2012. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patient-reported disease-specific function was measured using the 26-item Expanded Prostate Index Composite (EPIC) at baseline and 6 and 12 mo after enrollment. Mean treatment differences in function were compared by race using risk-adjusted generalized estimating equations. RESULTS AND LIMITATIONS: While all race/ethnic groups reported considerable declines in scores for urinary incontinence after radical prostatectomy (RP) when compared to active surveillance, African-American men reported a greater difference than white men did (adjusted difference-in-differences 8.4 points, 95% confidence interval 2.0-14.8; p=0.01). No difference in bother scores was noted and the overall proportion of explained variation attributable to race/ethnicity was relatively small in comparison to primary treatment and baseline function. No clinically significant racial variation was noted for the sexual, bowel, irritative voiding, or hormone domains. Limitations include the lack of well-established thresholds for clinical significance using the EPIC instrument. CONCLUSION: While these data demonstrate that incontinence at 1 yr after RP may be worse for African-American compared to white men, the difference appears to be modest overall. Treatment selection and baseline function explain a much greater proportion of the variation in function after treatment. PATIENT SUMMARY: We observed that the effect of treatment for prostate cancer on patient-reported function did not vary dramatically by race/ethnicity. Compared to white men, African-American men experienced a somewhat more pronounced decline in urinary continence after radical prostatectomy, but the corresponding changes in bother scores were not significantly different between the two groups.

African Americans Have Better Outcomes for Five Common Gastrointestinal Diagnoses in Hospitals With More Racially Diverse Patients.

OBJECTIVES: We sought to characterize the relationship between hospital inpatient racial diversity and outcomes for African-American patients including rates of major complications or mortality during hospitalization for five common gastrointestinal diagnoses. METHODS: Using the 2012 National Inpatient Sample database, hospital inpatient racial diversity was defined as the percentage of African-American patients discharged from each hospital. Logistic regression was used to predict major complication rates or death, long length of stay, and high total charges. Control variables included age, gender, payer type, patient location, area-associated income quartile, hospital characteristics including size, urban vs. rural, teaching vs. nonteaching, region, and the interaction of the percentage of African Americans with patient race. RESULTS: There were 848,395 discharges across 3,392 hospitals. The patient population was on average 27% minority (s.d.±21%) with African Americans accounting for 14% of all patients. Overall, African-American patients had higher rates of major complications or death relative to white patients (adjusted odds ratio (aOR) 1.19; 95% confidence interval (CI) 1.16-1.23). However, when treated in hospitals with higher patient racial diversity, African-American patients experienced significantly lower rates of major complications or mortality (aOR 0.80; 95% CI 0.74-0.86). CONCLUSIONS: African Americans have better outcomes for five common gastrointestinal diagnoses when treated in hospitals with higher inpatient racial diversity. This has major ramifications on total hospital charges.

Time trends in upper gastrointestinal diseases and Helicobacter pylori infection in a multiracial Asian population--a 20-year experience over three time periods.

BACKGROUND: Marked epidemiological changes in upper gastrointestinal diseases and Helicobacter pylori infection have taken place in the Asian Pacific region. In particular, differences with respect to race in the multiracial Asian population in Malaysia have been important and interesting. AIM: A time trend study of upper gastrointestinal disease and H. pylori infection in three time periods: 1989-1990, 1999-2000 and 2009-2010 spanning a period of 20 years was carried out. METHODS: Consecutive first time gastroscopies carried out on patients attending the University of Malaya Medical Center were studied. Diagnoses and H. pylori infection status were carefully recorded. RESULTS: A steady decline in prevalence of duodenal ulcer (DU) and gastric ulcer (GU) from 21.1% to 9.5% to 5.0% and from 11.9% to 9.4% to 9.9% while an increase in erosive oesophagitis (EO) from 2.0% to 8.4% to 9.5% (chi-square for trend; P < 0.001) for the periods 1989-1990, 1999-200 and 2009-2010 were observed. The overall prevalence of H. pylori had also decreased from 51.7% to 30.3% to 11.1% for the same periods of time. The proportion of H. pylori positive ulcers had also decreased: DU (90.1%-69.8%-28.9%) and GU (86.6-56.8%-18.9%) (P < 0.001). This was observed in Malays, Chinese and Indians but the difference over time was most marked in Malays. There was a steady decline in the proportion of patients with gastric and oesophageal cancers. CONCLUSIONS: Peptic ulcers have declined significantly over a 20-year period together with a decline in H. pylori infection. In contrast, a steady increase in erosive oesophagitis was observed. Gastric and oesophageal squamous cell cancers have declined to low levels.

Ethnic variations in upper gastrointestinal hospitalizations and deaths: the Scottish Health and Ethnicity Linkage Study.

BACKGROUND: Upper gastrointestinal (GI) diseases are common, but there is a paucity of data describing variations by ethnic group and so a lack of understanding of potential health inequalities. We studied the incidence of specific upper GI hospitalization and death by ethnicity in Scotland. METHODS: Using the Scottish Health and Ethnicity Linkage Study, linking NHS hospitalizations and mortality to the Scottish Census 2001, we explored ethnic differences in incidence (2001-10) of oesophagitis, peptic ulcer disease, gallstone disease and pancreatitis. Relative Risks (RRs) and 95% confidence intervals were calculated using Poisson regression, multiplied by 100, stratified by sex and adjusted for age, country of birth (COB) and socio-economic position. The White Scottish population (100) was the reference population. RESULTS: Ethnic variations varied by outcome and sex, e.g. adjusted RRs (95% confidence intervals) for oesophagitis were comparatively higher in Bangladeshi women (209; 124-352) and lower in Chinese men (65; 51-84) and women (69; 55-88). For peptic ulcer disease, RRs were higher in Chinese men (171; 131-223). Pakistani women had higher RRs for gallstone disease (129; 112-148) and pancreatitis (147; 109-199). The risks of upper GI diseases were lower in Other White British and Other White [e.g. for peptic ulcer disease in men, respectively (74; 64-85) and (81; 69-94)]. CONCLUSION: Risks of common upper GI diseases were comparatively lower in most White ethnic groups in Scotland. In non-White groups, however, risk varied by disease and ethnic group. These results require consideration in health policy, service planning and future research.
