Published: December 2019

Abstract
Background
Consumption of moldy food has previously been identified as a risk factor for esophageal squamous cell carcinoma (ESCC) in high-risk countries; however, what contributing roles these dietary carcinogenic mycotoxins play in the etiology of ESCC are largely unknown.

Methods
A mycotoxin biomarker-incorporated, population-based case-control study was performed in Huaian area, Jiangsu Province, one of the two high-risk areas in China. Exposure biomarkers of aflatoxins (AF) and fumonisins (FN) were quantitatively analyzed using HPLC-fluorescence techniques.

Results
Among the cases (n = 190), the median levels of AF biomarker, serum AFB1-lysine adduct, and FN biomarker, urinary FB1, were 1.77 pg/mg albumin and 176.13 pg/mg creatinine, respectively. Among the controls (n = 380), the median levels of AFB1-lysine adduct and urinary FB1 were 1.49 pg/mg albumin and 56.92 pg/mg creatinine, respectively. These mycotoxin exposure biomarker levels were significantly higher in cases as compared to controls (p <  0.05 and 0.01, respectively). An increased risk to ESCC was associated with exposure to both AFB1 and FB1 (p <  0.001 for both).

Conclusions
Mycotoxin exposure, especially to AFB1 and FB1, was associated with the risk of ESCC, and a greater-than-additive interaction between co-exposures to these two mycotoxins may contribute to the increased risk of ESCC in Huaian area, China.
Energy drinks and population health: consumption pattern and adverse effects among Saudi population
Authors: Subaiea Gehad M. , Altebainawi Ali F. , Alshammari Thamir M. 
Published: December 2019

Abstract
Background
Caffeine containing energy drinks (EDs) are heavily consumed, particularly among young adults. The number of reports of caffeine intoxication from caffeinated EDs and problems related to caffeine dependence and withdrawal is increasing. The objective was to assess the knowledge and perceived beneficial effects of EDs consumers, to assess consumption patterns and determine the adverse effects experienced by different EDs consumer groups residing in Saudi Arabia.

Methods
An observational cross-sectional study with data from a randomly selected Saudi population was conducted during the period of January 15th, 2015, to April 15th, 2015, using a pre-tested 43-item questionnaire. The data were obtained and collected using interview questionnaires. Sociodemographic characteristics and data on EDs consumption patterns, the level of awareness among study subjects, and the purported benefits and reported adverse effects of EDs were collected. Frequency, percentage, and arithmetic means were calculated using Chi-square and ANOVA tests, and data with p < 0.05 were considered significant.

Results
Of the 816 individuals invited to participate in the study, 783 participants responded and completed interviews, response rate was 96%. Consumers attributed the popularity of EDs to massive advertising media (46.7%) and their stimulating and invigorating effects (37.5%). EDs are consumed by subjects for their effects on fatigue reduction (64.6%), increased alertness and focus (75.8%), and assistance during long driving trips (75.7%). Study subjects reported suffering from adverse effects, including mainly diuresis (53.7%), palpitations (50.7%), insomnia (50.7%). Importantly, an inverse association was identified between knowledge of EDs and consumption rate, and a proportional association was identified between experienced adverse effects and consumption frequency. Lower knowledge scores were identified in daily consumers than in 1–3 times monthly consumers; higher adverse events were experienced by daily consumers than by 1–3 times monthly consumers. The majority of consumers (84.6%) recommended that authorities should regulate EDs consumption.

Conclusions
Excessive EDs consumption is associated with an increased risk of experiencing several adverse events, which is commensurate with published studies. Increasing knowledge about EDs and their possible risks could decrease their consumption by the general public.

Authors: Machado Ausenda , Kislaya Irina , Larrauri Amparo , Matias Dias Carlos , Nunes Baltazar 
Published: December 2019

Abstract
Background
All aged individuals with a chronic condition and those with 65 and more years are at increased risk of severe influenza post-infection complications. There is limited research on cases averted by the yearly vaccination programs in high-risk individuals. The objective was to estimate the impact of trivalent seasonal influenza vaccination on averted hospitalizations and death among the high-risk population in Portugal.

Methods
The impact of trivalent seasonal influenza vaccination was estimated using vaccine coverage, vaccine effectiveness and the number of influenza-related hospitalizations and deaths. The number of averted events (NAE), prevented fraction (PF) and number needed to vaccinate (NVN) were estimated for seasons 2014/15 to 2016/17.

Results
The vaccination strategy averted on average approximately 1833 hospitalizations and 383 deaths per season. Highest NAE was observed in the ≥65 years population (85% of hospitalizations and 95% deaths) and in the 2016/17 season (1957 hospitalizations and 439 deaths). On average, seasonal vaccination prevented 21% of hospitalizations in the population aged 65 and more, and 18.5% in the population with chronic conditions. The vaccination also prevented 29% and 19.5% of deaths in each group of the high-risk population. It would be needed to vaccinate 3360 high-risk individuals, to prevent one hospitalization and 60,471 high-risk individuals to prevent one death.

Conclusion
The yearly influenza vaccination campaigns had a sustained positive benefit for the high-risk population, reducing hospitalizations and deaths. These results can support public health plans toward increased vaccine coverage in high-risk groups.
Research protocol local ingredients-based supplementary food as an alternative to corn-soya blends plus for treating moderate acute malnutrition among children aged 6 to 59 months: a randomized controlled non-inferiority trial in Wolaita

Published: December 2019

AbstractBackgroundIn Ethiopia, 12.5% of children below 5 years are wasted, and 9.7% are moderately wasted. The present strategy for the management of moderate acute malnutrition (MAM) is a supplementary feeding program; however, this is only provided to chronically food-insecure areas. This randomized controlled non-inferiority trial examines if Local ingredients-based supplement (LIBS) is as effective as corn-soya blends plus (CSB+) in treating moderate acute malnutrition among children aged 6–59 months.MethodsA randomized controlled non-inferiority trial will be conducted with moderately wasted children aged 6 to 59 months in Wolaita, Ethiopia. The calculated sample size is 324 (i.e. with 162 children in each of two arms, to be assigned by randomization). The daily ration will be: 100 g of LIBS plus 25.2 g of sugar with 8 ml oil in the intervention group, and 150 g of CSB+ with 16 ml of oil in the control group. These interventions will be provided for a maximum period of 12 weeks, with follow-up performed on a weekly basis. Data analysis will be done using SPSS and STATA software. Both intention-to-treat and per protocol analyses will be done. Hazard ratio and Kaplan-Meier (log rank) curves of survival analysis will be done to predict the probability of recovery rate. Logistic regression will be used to test for interactions between independent and dependent variables. Analysis of variances, t-tests, fisher’s exact test and chi-square tests will be used to assess baseline characteristics.ConclusionsThis paper will introduce to the existing research locally available nutritious foods which have the potential to enhance recovery from moderate acute malnutrition and to reduce the burden of malnutrition. The perceptions of mothers on feeding children with local ingredient-based supplementary food to assist recovery from moderate acute malnutrition will be the focus of in a qualitative study to follow; this will provide a further contribution in an evolving area of research.Trial registrationPan-African Clinical Trial Registration number:PACTR201809662822990, retrospectively registered on 11/09/2018.

Published: December 2019

Abstract
Background
There is growing recognition of the importance of educating health professional students to enhance their competence in collaborating with individuals from other health professions in the area of global health. This study aimed to identify the performance levels in interprofessional global health competencies (IGHC) of health professional students, their educational needs, and the strategies for successfully developing IGHC.

Methods
This study used a mixed methods design involving an online survey followed by focus group interviews. A sample of 325 fourth-year undergraduate students from 14 health-related majors completed a self-report online survey (38.8% response rate). The performance of IGHC was measured on a five-point Likert scale using the IGHC items developed by the Consortium of Universities for Global Health. Additionally, 12 senior students and five professors in global health-related majors participated in focus group interviews. The students’ educational needs and priorities were analysed using the Borich needs assessment and the Locus for Focus model.

Results
The participants’ IGHC mean score was 3.11 (SD = 0.55) and differed by previous global health activity experiences (t = − 2.10, p = .037). Nine competencies in six domains using the Locus for Focus model were identified as a priority for global health education. Suggested strategies to enhance IGHC included establishing IGHC education in formal curricula, developing value-based content and outcomes, and engaging students in learning activities.

Conclusions
It is necessary to design an interprofessional pre-departure course to achieve the priority IGHC and to organise learning activities where there is cooperation in problem solving while applying the expertise of each major within resource-limited settings. This study supports future health professional education that should foster enhanced roles and scopes of practice as changing agents to assure the achievement of sustainable development goals.

Published: December 2019

AbstractBackgroundVideographic material of animals can contain inapparent signals, such as color changes or motion that hold information about physiological functions, such as heart and respiration rate, pulse wave velocity, and vocalization. Eulerian video magnification allows the enhancement of such signals to enable their detection. The purpose of this study is to demonstrate how signals relevant to experimental physiology can be extracted from non-contact videographic material of animals.ResultsWe applied Eulerian video magnification to detect physiological signals in a range of experimental models and in captive and free ranging wildlife. Neotenic Mexican axolotls were studied to demonstrate the extraction of heart rate signal of non-embryonic animals from dedicated videographic material. Heart rate could be acquired both in single and multiple animal setups of leucistic and normally colored animals under different physiological conditions (resting, exercised, or anesthetized) using a wide range of video qualities. Pulse wave velocity could also be measured in the low blood pressure system of the axolotl as well as in the high-pressure system of the human being. Heart rate extraction was also possible from videos of conscious, unconstrained zebrafish and from non-dedicated videographic material of sand lizard and giraffe. This technique also allowed for heart rate detection in embryonic chickens in ovo through the eggshell and in embryonic mice in utero and could be used as a gating signal to acquire two-phase volumetric micro-CT data of the beating embryonic chicken heart. Additionally, Eulerian video magnification was used to demonstrate how vocalization-induced vibrations can be detected in infrasound-producing Asian elephants.ConclusionsEulerian video magnification provides a technique to extract inapparent temporal signals from videographic material of animals. This can be applied in experimental and comparative physiology where contact-based recordings (e.g., heart rate) cannot be acquired.

Authors: Yulianda Dicky , Sati Andy Indra , Makhmudi Akhmad , Gunadi  
Published: December 2019

Abstract
Background
Hirschsprung-associated enterocolitis (HAEC) is a life-threatening complication of Hirschsprung disease (HSCR), that might occur preoperatively. We investigated the risk factors of preoperative HAEC.

Method
We retrospectively reviewed all medical records of HSCR patients admitted at Dr. Sardjito Hospital, Indonesia from March 2012 until March 2015. Diagnosis of HAEC was determined using the Delphi scoring system.

Results
Sixty-one HSCR patients were involved in this study, of whom 48 were males and 13 females. Eighteen percent (11/61) patients had a preoperative HAEC. The most common findings of the HAEC score found in our patients were distended abdomen (100%) and dilated loops of bowel (100%), followed by lethargy (72.7%), cut-off sign in rectosigmoid with absence of distal air (72.7%), leukocytosis (72.7%), and shift to left (63.6%). There was no association between gender, age of HSCR diagnosis, early/late diagnosis during neonatal period, aganglionosis type, albumin level nor body mass index with preoperative HAEC (p = 0.69, 0.76, 0.33, 1.0, 0.86, and 0.50, respectively). In addition, the maternal age, gestational age, and maternal education level also did not correlate with the development of preoperative HAEC (p = 0.71, 0.59, and 0.32, respectively).

Conclusion
The incidence of preoperative HAEC in our hospital is considered relatively moderate, with the most common findings of distended abdomen and dilated loops of bowel. None of the identified risk factors have an association with the development of HAEC in our patients.
RETRACTED ARTICLE: Circular RNA ABCB10 promotes hepatocellular
carcinoma progression by increasing HMG20A expression by sponging
miR-670-3p
Authors: Fu Yu , Cai Limin , Lei Xuexue , Wang Dunwei 
Published: December 2019

Abstract
Background/aims
The dysregulation of circABCB10 may play an critical role in tumor
progression. However, its function in liver cancer (HCC) is still unclear.
Therefore, this experimental design is based on circABCB10 to explore the
pathogenesis of HCC.

Methods
The expression of circABCB10 and miR-670-3p in HCC tissues was
detected by RT-qPCR. CCK-8, Brdu incorporation, colony formation and transwell
assays were used to determine the effect of circABCB10 on HCC cell proliferation
and migration. Target gene prediction and screening, luciferase reporter assays
were used to validate downstream target genes of circABCB10 and miR-670-3p.
HMG20A expression was detected by RT-qPCR and Western blotting. The tumor
changes in mice were detected by in nude mice.

Results
CircABCB10 was significantly increased in HCC tissues and cell
lines, and high CircABCB10 expression was directly associated with low survival
in HCC patients. Silencing of circABCB10 inhibited proliferation and invasion of
hepatocellular carcinoma. In addition, circABCB10 acted as a sponge of
miR-670-3p to upregulate HMG20A expression. In addition, overexpression of
miR-670-3p or knockdown of HMG20A reversed the carcinogenic effects of
circABCB10 in HCC. There was a negative correlation between the expression of
circABCB10 and miR-670-3p, and a positive correlation between the expression of
circABCB10 and HMG20A in HCC tissues.

Conclusion
circABCB10 promoted HCC progression by modulating the
miR-670-3p/HMG20A axis, and circABCB10 may be a potential therapeutic target for
HCC.

Plasmodium vivax severe imported malaria in two migrants in France
Authors: Izri Arezki , Cojean Sandrine , Leblanc Claire , Cohen Yves , Bouchaud Olivier , Durand Rémy 
Published: December 2019

Abstract
Background
With less than one severe case per year in average, Plasmodium vivax is very rarely associated with severe imported malaria in France. Two cases of P. vivax severe malaria occurred in patients with no evident co-morbidity. Interestingly, both cases did not occur at the primary infection but during relapses.

Case presentations
Patient 1: A 27-year old male, born in Afghanistan and living in France since 2012, was admitted on August 2015 to the Avicenne hospital because of abdominal pain, intense headache, fever and hypotension. The patient was haemodynamically unstable despite 5 L of filling solution. A thin blood film showed P. vivax trophozoites within the red blood cells. To take care of the septic shock, the patient was given rapid fluid resuscitation, norepinephrine (0.5 mg/h), and intravenous artesunate. Nested polymerase chain reactions of the SSUrRNA gene were negative for Plasmodium falciparum but positive for P. vivax. The patient became apyretic in less than 24H and the parasitaemia was negative at the same time. Patient 2: A 24-year old male, born in Pakistan and living in France, was admitted on August 2016 because of fever, abdominal pain, headache, myalgia, and nausea. The last travel of the patient in a malaria endemic area occurred in 2013. A thin blood film showed P. vivax trophozoites within the red blood cells. The patient was treated orally by dihydroartemisinin-piperaquine and recovered rapidly. Nine months later, the patient returned to the hospital with a relapse of P. vivax malaria. The malaria episode was uncomplicated and the patient recovered rapidly. Three months later, the patient came back again with a third episode of P. vivax malaria. Following a rapid haemodynamic deterioration, the patient was transferred to the intensive care unit of the hospital. In all the patient received 10 L of filling solution to manage the septic shock. After 5 days of hospitalization and a specific treatment, the patient was discharged in good clinical conditions.

Conclusion
Clinicians should be aware of the potential severe complications associated with P. vivax in imported malaria, even though the primary infection is uncomplicated.
Adherence to the low carbohydrate diet and the risk of breast Cancer in Iran
Authors: Sasanfar Bahareh , Toorang Fatemeh , Esmaillzadeh Ahmad , Zendehdel Kazem 
Published: December 2019

AbstractBackgroundPrevious studies on the link between macronutrients and breast cancer have mostly focused on individual macronutrients rather than their combination. This study investigates the association between adherence to a low carbohydrate diet and odds of breast cancer among women.MethodsThis hospital-based case-control study was carried out on 412 women with pathologically confirmed breast cancer within the past year and 456 apparently healthy controls that were matched in terms of age and residential place. Dietary data was collected using a 168-item validated FFQ. Participants were classified in terms of quintiles of percentages of energy intake from carbohydrates, proteins, and fats. Then, individuals in the highest quintile of fat and protein intake were given a score of 5 and those in the lowest quintile of these macronutrients were given a score of 1. Participants in the other quintiles of these macronutrients were given the corresponding score. In terms of carbohydrate intake, those in the highest quintile received a score of 1 and those in the lowest quintile received 5. The scores were then summed up to calculate the total low carbohydrate diet (LCD) score, which varied from 3 to 15. A higher score meant greater adherence to a low carbohydrate diet.ResultsThe mean age of study participants was 45.2 y and mean BMI was 28.4 kg/m2. Mean LCD score of participants was 8.9 ± 2.5 (8.9 ± 2.6 in cases and 9.0 ± 2.5 in controls). Although no significant association was observed between adherence to the LCD score and odds of breast cancer in the study population, a trend toward significant positive association was seen between consumption of LCD and odds of breast cancer in postmenopausal women; after controlling for several potential confounders, individuals in the third quartile of LCD score were 1.94 times more likely to have breast cancer than those in the lowest quartile (95% CI: 1.00, 3.76). This association strengthened after controlling for dietary variables (2.50; 1.18–5.32). Even after further adjustment for BMI, this association remained significant (2.64, 1.23–5.67). No significant relationship was observed in premenopausal women, either before or after controlling for confounders.ConclusionAdherence to LCD may be associated with increased odds of breast cancer in postmenopausal women. Prospective cohort studies are needed to confirm these findings.

Authors: Nwafia Ifeyinwa N. , Ohanu Martin E. , Ebede Samuel O. , Ozumba Uchenna C. 
Published: December 2019

Abstract
Background
The use of antibiotic agents in the treatment of infectious diseases has greatly contributed to the decrease in morbidity and mortality, but these great advances in treatment are being undermined by the rapidly increasing antimicrobial resistant organisms. Extended-spectrum beta-lactamases are enzymes hydrolyzing the beta lactam antibiotics, including third generation cephalosporins and monobactams but not cephamycins and carbapenems. They pose a serious global health threat and have become a challenge for health care providers. The aim of this research was to assess the prevalence of extended-spectrum beta-lactamase producing Escherichia coli in University of Nigeria Teaching Hospital Ituku-Ozalla Enugu and to detect the risk factors for acquisition of the resistant organism. To proffer advice on antibiotic stewardship in clinical practice and public health interventions, to curb the spread of the resistant organisms in the hospital.

Results
Out of the 200 E. coli isolates, 70 (35.00%) were confirmed positive for extended-spectrum beta-lactamase production. Fifty-three (75.7%) were from hospital acquired infections. All the isolates were resistant to ampicillin, tetracycline and chloramphenicol while 68 (97.14%) of the 70 isolates were susceptible to imipenem. BlaTEM, blaSHV and blaTEM were detected in 66 (94%) of the 70 isolates. The ESBL bla genes detected were blaCTX-M (n = 26; 37.14%), blaTEM (n = 7; 10.00%), blaSHV (n = 2; 2.86%), blaCTX-M/TEM (n = 7; 10.0%), blaCTX-M/SHV (n = 14; 20.0%) and blaCTX-M/TEM/SHV (n = 10; 14.29%). The three bla genes were not detected in 4 (5.71%) of the isolates. Recent surgery, previous antibiotic and intensive care unit admission were the associated risk factors to infections caused by extended-spectrum beta-lactamase producing E. coli.

Conclusion
There is a high rate of infections caused by extended-spectrum beta-lactamase producing E. coli. Recent surgery, previous antibiotic and intensive care unit admission were associated risk factors.
