Published: September 2019

Background: Advanced age is the most important risk factor for pancreatic cancer and about half of patients are diagnosed with metastatic disease. In the first-line setting, multidrug chemotherapy regimens were shown to be more effective than gemcitabine alone. However, the older population was under-represented in randomized clinical trials. We aimed to describe the clinical profile of older patients with metastatic pancreatic cancer and their survival outcomes. Materials and methods: This was a retrospective, unicentric study that included patients diagnosed with metastatic pancreatic cancer (non-neuroendocrine), aged 65 years and over. Results: The study population comprised 196 patients. The median age was 73 years; 67% of these patients presented Eastern Cooperative Oncology Group performance status (ECOG) ⩽ 1 and the median Charlson Comorbidity score was 10. Chemotherapy was given to 89% of the patients. The most frequently used chemotherapy regimens were gemcitabine (44%), 5-fluorouracil and oxaliplatin [FOLFOX; 26%], and 5-fluorouracil, oxaliplatin and irinotecan (FOLFIRINOX; 20%). Patients treated with FOLFIRINOX were younger and they presented better performance status. After a median follow up of 19.8 months, the median overall survival (OS) was of 7.2 months and the median time to first-line-treatment failure was 4.6 months. Among patients treated with chemotherapy, the median OS was highest for those treated with FOLFIRINOX (13.8 months), as compared with FOLFOX (7.0 months) or gemcitabine (6.7 months); p = 0.004. Nonetheless, treatment with FOLFIRINOX was associated with increased risk of severe toxicity ( p = 0.008). Conclusion: Older patients with metastatic pancreatic cancer benefit from palliative chemotherapy, and FOLFIRINOX is a therapeutic option in rigorously selected older patients.

Published: September 2019

Background: Classification of disease and interventions in traditional medicine (TM) is necessary for standardised coding of information. Currently, in Iran, there is no standard electronic classification system for disease and interventions in TM. Objective: The current study aimed to develop a national framework for the classification of disease and intervention in Persian medicine based on expert opinion. Method: A descriptive cross-sectional study was carried out in 2018. The existing systems for the classification of disease and interventions in TM were reviewed in detail, and some of the structural and content characteristics were extracted for the development of the classification of Iranian traditional medicine. Based on these features, a self-administered questionnaire was developed. Study participants (25) were experts in the field of Persian medicine and health information management in Tehran medical universities. Results: Main axes for the classification of disease and interventions were determined. The most important applications of the classification system were related to clinical coding, policymaking, reporting of mortality and morbidity data, cost analysis and determining the quality indicators. Half of the participants (50%) stated that the classification system should be designed by maintaining the main axis of the World Health Organization classification system and changing the subgroups if necessary. A computer-assisted coding system for TM was proposed for the current study. Conclusion: Development of this classification system will provide nationally comparable data that can be widely used by governments, national organisations and academic researchers.
Percentage low-density lipoprotein-cholesterol response to a given statin dose is not fixed across the pre-treatment range: Real world evidence from clinical practice: Data from the ESC-EORP EUROASPIRE V Study

Aims Recent European guidelines recommend in patients with atherosclerotic cardiovascular disease to achieve a reduction of low-density lipoprotein-cholesterol of at least 50% if the baseline low-density lipoprotein-cholesterol level is between 1.8 and 3.5 mmol/L. Systematic reviews have associated a given statin/dose combination with a fixed percentage low-density lipoprotein-cholesterol response. Algorithms for detecting cases and estimating the prevalence of familial hypercholesterolaemia often rely on such fixed percentage reductions. Methods and results We used data from 915 coronary patients participating in the EUROASPIRE V study in whom atorvastatin or rosuvastatin therapy was initiated at hospital discharge and who were still using these drugs at the same dose at a follow-up visit 6 or more months later. Pre and on-treatment low-density lipoprotein-cholesterol levels were compared across the full low-density lipoprotein-cholesterol range. The prevalence of FH was estimated using the Dutch Lipid Clinic Network criteria, once using observed pre-treatment low-density lipoprotein-cholesterol and once using imputed pre-treatment low-density lipoprotein-cholesterol by following the common strategy of applying fixed correction factors to on-treatment low-density lipoprotein-cholesterol. Inter-individual variation in the low-density lipoprotein-cholesterol response to a fixed statin and dose was considerable, with a strong inverse relation of percentage reductions to pre-treatment low-density lipoprotein-cholesterol. The percentage low-density lipoprotein-cholesterol response was markedly lower at the left end of the pre-treatment low-density lipoprotein-cholesterol range especially for levels less than 3 mmol/L. The estimated prevalence of familial hypercholesterolaemia was 2% if using observed pre-treatment low-density lipoprotein-cholesterol and 10% when using imputed low-density lipoprotein-cholesterol. Conclusion The inter-individual variation in the percentage low-density lipoprotein-cholesterol response to a given dose of a statin is largely dependent on the pre-treatment level: the lower the pre-treatment low-density lipoprotein-cholesterol level the smaller the percentage low-density lipoprotein-cholesterol reduction. The use of uniform correction factors to estimate pre-treatment low-density lipoprotein-cholesterol is not justified.

Published: September 2019

Objectives: Being the most common type of oral malignancies, oral squamous cell carcinoma is initiated by epithelial dysplasia, which can be marked by the expression of nuclear factor kappa B and cyclooxygenase 2. Curcumin has been known for its anti-cancer potential. The objective of this study was to evaluate the anti-cancer potential of curcumin on oral squamous cell carcinoma based on the expression of the nuclear factor kappa B and cyclooxygenase 2 during epithelial dysplasia stage. Methods: This experimental study was performed on 35 Sprague Dawley rats at the Veterinary Medicine Faculty, Bogor Agricultural Institute, Indonesia. At the beginning of the experiments, all rats were induced by 100 µg 0.5% 7,12-dimethylbenz(a)anthracene every 2 days for the duration of 28 days. Once epithelial dysplasia stage was reached, all rats were then randomly divided into control group (that did not receive curcumin) or the experimental group (the group that received curcumin for the next 4 weeks). After 4 weeks, the histopathological examination of haematoxylin and eosin and immunohistochemistry examination were conducted. Data were gathered and analyzed by using the Wilcoxon–Mann–Whitney test. Results: The results of the current study revealed that the experimental group showed significantly less nuclear factor kappa B (p < 0.01) and cyclooxygenase 2 (p = 0.03) expressions compared to the control group. Conclusion: The results of the study suggested that curcumin was effective in suppressing nuclear factor kappa B and cyclooxygenase 2 expression in experimentally induced oral squamous cell carcinoma. Future studies investigating curcumin anti-cancer potential in a further stage of oral squamous cell carcinoma, as well as the involvement of other components that might improve curcumin anti-cancer potential, are of importance.

Published: September 2019

Objectives Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are immunosuppressive viruses in cats that increase their susceptibility to zoonotic pathogens. This study aimed to determine the occurrence of one or both viruses, the risk factors associated with infection, and to develop further recommendations. Methods This was a cross-sectional study conducted at the Veterinary Faculty of Eduardo Mondlane University, Mozambique, between March and December 2017, in 145 cats. From each of 145 cats, we took 1.5 ml of blood by jugular puncture for detection of antibodies to FIV and FeLV antigens in whole blood using a commercial test kit, DFV Test FeLV/FIV. Results We found an overall prevalence of 11.0% and 14.5% for FIV antibodies and FeLV antigens, respectively, with four (2.8%) cats coinfected by both pathogens. Male cats were more likely to be infected with FIV (odds ratio [OR] 1.1, 95% confidence interval [CI] 0.3–4.0) compared with female cats. Clinically ill cats were more likely to have a positive result for FeLV antigen infection (OR 18.8, 95% CI 5.2–68.3). Moreover, cats living in suburban areas have a greater chance of a positive result for FeLV infection (OR 3.7, 95% CI 1.4–9.6) compared with cats living in urban areas. Conclusions and relevance FIV and FeLV occur in cats from Maputo and possibly all over the country. Further studies should be conducted in Mozambique and other African countries to define the burden of both pathogens in cats, coinfection with other zoonotic pathogens and the possible role played by the cats on the transmission of zoonotic and opportunistic diseases to humans.

Published: September 2019

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used to rescue patients with cardiac arrest refractory to conventional therapy, necessitating evaluation of factors that may affect outcomes. Methods: A single-center retrospective review of pediatric patients (<21 years old) who underwent ECPR from January 2010 to November 2017. Comparisons between nonsurvivors and survivors, to decannulation and discharge, were made. Factors associated with survival and rate of complications were examined. Results: Seventy patients were supported with ECPR. Forty-nine (70%) patients survived to decannulation and 38 (54%) patients to discharge. There was no statistical difference between baseline characteristics of survivors and nonsurvivors, including age at cannulation, weight (kg), time to cannulation (minutes), and total time on extracorporeal membrane oxygenation (hours). Survivors to discharge had significantly higher pH prior to cannulation compared to nonsurvivors (7.11 ± 0.24 vs 6.97 ± 0.21, P = .01). Of all, 23.2% of patients received renal replacement therapy (RRT), 39.4% had significant bleeding, 22.5% had thrombotic complications, and 68.8% had neurologic injury on imaging studies. A greater number of nonsurvivors received RRT compared to survivors to discharge (35.5% vs 10.8%, P = .02). There were no differences in bleeding or thrombotic complications or radiographically established neurologic injury. Conclusions: Although ECPR effectively increases overall survival, a better characterization of long-term outcomes is needed.
Mixed Messages: I. The Consequences of Communicating Negative Statements Within Emotional Support Messages to Cancer Patients
Authors: Ray Colter D , Floyd Kory , Tietsort Cris J , Veluscek Alaina M , Otmar Christopher D , Hashi Emi C , Fisher Rosalie 
Published: September 2019

Background: Not all emotional support messages consist purely of positive statements. Some emotional support messages received by cancer patients simultaneously communicate statements of caring but also negative statements, such as criticisms of patients’ actions. Objective: This study tests if a negative statement occurring within an emotional support message affects cancer patients’ perceptions of the effectiveness of the entire emotional support message as well as the perceived competence of the supporter communicating the emotional support message. Methods: Cancer patients watched video recordings of emotional support messages and subsequently provided ratings on message effectiveness and supporter competence. Some emotional support messages included negative statements, whereas other messages did not. Results: Messages that included a negative statement were rated lower on message effectiveness than messages without negative statements. Cancer patients rated supporters communicating messages with a negative statement as having significantly less competence than those who did not communicate a negative statement. Conclusion: A single negative statement occurring within an emotional support message may result in cancer patients viewing the emotional support as less effective and the supporter as less competent.

Published: September 2019

Traditional tuberculosis (TB) epidemiology reports rarely provide a detailed analysis of TB incidence in particular geographic locations and among diverse population groups. Western Sydney Local Health District (WSLHD) has one of the highest TB incidence rates in Australia, and we explored whether more detailed epidemiological analysis could provide a better overview of the local disease dynamics.Using multiple relevant data sources, we performed a retrospective descriptive study of TB cases diagnosed within the WSLHD from 2006 to 2015 with a specific focus on geographic hotspots and the population structure within these hotspots.Over the study period nearly 90% of Western Sydney TB cases were born in a high TB incidence country. The TB disease burden was geographically concentrated in particular areas, with variable ethnic profiles in these different hotspots. The most common countries of birth were India (33.0%), the Philippines (11.4%) and China (8.8%). Among the local government areas in Western Sydney, Auburn had the highest average TB incidence (29.4 per 100 000) with exceptionally high population-specific TB incidence rates among people born in Nepal (average 223 per 100 000 population), Afghanistan (average 154 per 100 000 population) and India (average 143 per 100 000 population).Similar to other highly cosmopolitan cities around the world, the TB burden in Sydney showed strong geographic concentration. Detailed analysis of TB patient and population profiles in Western Sydney should guide better contextualised and culturally appropriate public health strategies.

Abstract

Background
Pesticide residue contamination of surface water in agricultural areas can have adverse effects on the ecosystem. We have performed an integrated chemical and bioanalytical profiling of surface water samples from Swedish agricultural areas, aiming to assess toxic activity due to presence of pesticides. A total of 157 water samples were collected from six geographical sites with extensive agricultural activity. The samples were chemically analyzed for 129 commonly used pesticides and transformation products. Furthermore, the toxicity was investigated using in vitro bioassays in the water samples following liquid–liquid extraction. Endpoints included oxidative stress response (Nrf2 activity), estrogen receptor (ER) activity, and aryl hydrocarbon receptor (AhR) activity. The bioassays were performed with a final enrichment factor of 5 for the water samples. All bioassays were conducted at non-cytotoxic conditions.

Results
A total of 51 pesticides and transformation products were detected in the water samples. Most of the compounds were herbicides, followed by fungicides, insecticides and transformation products. The highest total pesticide concentration in an individual sample was 39 µg/L, and the highest median total concentration at a sample site was 1.1 µg/L. The largest number of pesticides was 31 in a single sample. We found that 3% of the water samples induced oxidative stress response, 23% of the samples activated the estrogen receptor, and 77% of the samples activated the aryl hydrocarbon receptor. Using Spearman correlation coefficients, a statistically significant correlation was observed between AhR and ER activities, and AhR activity was strongly correlated with oxidative stress in samples with a high AhR activity. Statistically significant relationships were observed between bioactivities and individual pesticides, although the relationships are probably not causal, due to the low concentrations of pesticides. Co-occurrence of non-identified chemical pollutants and naturally occurring toxic compounds may be responsible for the induced bioactivities.

Conclusions
This study demonstrated that integrated chemical analysis and bioanalysis can be performed in water samples following liquid/liquid extraction with a final enrichment factor of 5. AhR and ER activities were induced in water samples from agricultural areas. The activities were presumably not caused by the occurrence of pesticides, but induced by other anthropogenic and natural chemicals.
BINDER: computationally inferring a gene regulatory network for Mycobacterium abscessus

Published: September 2019

AbstractBackgroundAlthough many of the genic features inMycobacterium abscessushave been fully validated, a comprehensive understanding of the regulatory elements remains lacking. Moreover, there is little understanding of how the organism regulates its transcriptomic profile, enabling cells to survive in hostile environments. Here, to computationally infer the gene regulatory network forMycobacterium abscessuswe propose a novel statistical computational modelling approach: BayesIan gene regulatory Networks inferreD via gene coExpression and compaRative genomics (BINDER). In tandem with derived experimental coexpression data, the property of genomic conservation is exploited to probabilistically infer a gene regulatory network inMycobacterium abscessus.Inference on regulatory interactions is conducted by combining ‘primary’ and ‘auxiliary’ data strata. The data forming the primary and auxiliary strata are derived from RNA-seq experiments and sequence information in the primary organismMycobacterium abscessusas well as ChIP-seq data extracted from a related proxy organismMycobacterium tuberculosis. The primary and auxiliary data are combined in a hierarchical Bayesian framework, informing the apposite bivariate likelihood function and prior distributions respectively. The inferred relationships provide insight to regulon groupings inMycobacterium abscessus.ResultsWe implement BINDER on data relating to a collection of 167,280 regulator-target pairs resulting in the identification of 54 regulator-target pairs, across 5 transcription factors, for which there is strong probability of regulatory interaction.ConclusionsThe inferred regulatory interactions provide insight to, and a valuable resource for further studies of, transcriptional control inMycobacterium abscessus, and in the family ofMycobacteriaceaemore generally. Further, the developed BINDER framework has broad applicability, useable in settings where computational inference of a gene regulatory network requires integration of data sources derived from both the primary organism of interest and from related proxy organisms.

Published: September 2019

Abstract

Background
We aimed to evaluate the prevalence of foot and/or ankle arthritis (FAA) and its impact on clinical indices in patients with rheumatoid arthritis (RA).

Methods
This cross-sectional study used data from the Korean College of Rheumatology Biologics & Targeted therapy registry to observe clinical outcomes of patients undergoing biologics therapy and conventional therapy. FAA was defined as ≥1 tender or swollen joint in the ankle and/or 1st-5th metatarsophalangeal (MTP) joints. Disease Activity Score 28 (DAS28), Routine Assessment of Patient Index Data 3 (RAPID3), Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI) were assessed.

Results
Among 2046 patients, 598 had FAA. The ankle joint was the most commonly involved joint in FAA (tender joint, 71.4%; swollen joint, 59.5%), followed by the third and second MTP joints. Patients with FAA showed higher DAS28, RAPID3, SDAI, and CDAI scores. FAA presence was significantly associated with non-remission as per DAS28-ESR (odds ratio, 3.4; 95% confidence interval, 2.0–5.8), DAS28-CRP (3.6, 2.4–5.3), SDAI (6.3, 2.8–14.6), CDAI (7.6, 2.4–24.3), and RAPID3 (5.6, 2.7–11.5) indices on adjusting for age, sex, disease duration, presence of rheumatoid factor, presence of anti-cyclic citrullinated peptide antibody, lung disease, use of methotrexate, and previous use of biological disease-modifying anti-rheumatic drugs. Patients with FAA were less likely to achieve remission of SDAI (n = 6, 1.0%) and CDAI (n = 3, 0.5%) than that of DAS28-ESR (n = 21, 3.5%), DAS28-CRP (n = 38, 6.4%), and RAPID3 (n = 12, 2.0%).

Conclusions
FAA represents a severe disease activity and is an independent risk factor for non-remission in patients with RA.
