Abstract
Background

To review the international literature on community-based interventions aiming to improve the oral health of Indigenous adolescents and identify which demonstrate a positive impact.

Methods

Data sources were MEDLINE, EMBASE, CINAHL, SCOPUS, the COCHRANE library and the Australian Indigenous Health Info Net. Articles were included where they: were published in English from 1990 onwards; described oral health outcomes for Indigenous adolescents aged 10 to 19 years; implemented a community based oral health intervention. The Quality Assessment Tool for Quantitative Studies from the Effective Public Health Practice Project was applied.

Results

Nine studies met inclusion criteria; two rated strong in quality; only one study was conducted with an urban community; five reported moderate community engagement. Five intervention strategies were identified, and schools were the most common setting reported. Statistically significant improvements were described in eight studies with the most frequently reported outcome being change in decayed missing or filled teeth.

Conclusions

Few good quality peer reviewed international studies of community-based oral health interventions which address the needs of Indigenous adolescents exist. Studies must include strong Indigenous community leadership and governance at all stages of the research, adopt participatory action-based research approaches, and are required in urban communities.

Registration

The PRISMA checklist of items to include when reporting a systematic review were followed and this review was registered with the PROSPERO register (number: CRD42018084673).

Abstract
Background: In recent years, methamphetamine regular use has increased noticeably in Iran, and this can have harmful consequences for the health of individuals and society. Therefore, the aim of this study is to investigate the consequences of methamphetamine regular use in Tehran.Methods: This qualitative content analysis study was carried out by using conventional approach. Date were collected through observation and in-depth interview with 20 regular users of methamphetamine adult in Tehran (15 males and 5 female). Participants were selected through snowball and purposeful sampling method which continued until data saturation. Guba and Lincoln criteria were used to assess the strength of the research.Results: The extraction of the codes resulted in three main categories, including: 1. The short-term consequences, consisting of the sub-categories of individual and social consequences 2. The long-term consequences, consisting of the sub-categories of psychological and physical consequences, high risk behaviors, severely decayed memory and changes in the eating pattern. 3. hallucinations and delusions including the sub-categories of visual and auditory hallucinations, delusion of suspicion and delusion of having supernatural power.Conclusion: Methamphetamine regular use has serious adverse effects on overall health of individuals. Therefore, implementing educational programs in order to raise awareness and changing attitudes about the short and long term consequences of using methamphetamine in high risk group is highly recommended.

Published: March 2020

Abstract
Background: Belonging to lineage Ⅰ of Brassicaceae, Camelina sativa is formed by two hybridizations of three species (three sub-genomes). The three sub-genomes were diverged from a common ancestor, likely derived from lineage Ⅰ (Ancestral Crucifer karyotype, ACK). The karyotype evolutionary trajectories of the C. sativa chromosomes are currently unknown. Here, we managed to adopt a telomere-centric theory proposed previously to explain the karyotype evolution in C. sativa . Results: By characterizing the homology between A. lyrata and C. sativa chromosomes, we inferred ancestral diploid karyotype of C. sativa (ADK), including 7 ancestral chromosomes, and reconstructed the evolutionary trajectories leading to the formation of extant C. sativa genome. The process involved 2 chromosome fusions. We found that sub-genomes Cs-G1 and Cs-G2 may share a closer common ancestor than Cs-G3. Together with other lines of evidence from Arabidopsis, we propose that the Brassicaceae plants, even the eudicots, follow a chromosome fusion mechanism favoring end-end joining of different chromosomes, rather than a mechanism favoring the formation circular chromosomes and nested chromosome fusion preferred by the monocots. Conclusions: The present work will contribute to understanding the formation of C. sativa chromosomes, providing insight into Brassicaceae karyotype evolution.

Abstract
Background: Ralstonia solanacearum is one of the most notorious soil-borne phytopathogens. It causes a severe wilt disease with deadly effects on many economically important crops. The microbita of disease-suppressive soils are thought that they can contribute to the disease resistance of crop plants, thus, to conduct the microbial community and their interaction characteristics between suppressive soil (SS) and conducive soil (CS) will help to understand resistance mechanism. Here, the bacterial community structure, correlation analysis with soil chemical properties, interaction network of SS (nearly no disease in three years), and CS (suffered heavy bacterial wilt disease) were analyzed.
Results: Compared with CS, a higher bacterial community diversity index was found in SS , and the relative abundance of main genera Bacillus , Gaiellales , Roseiflexus , Gemmatimonadaceae , Nocardioides , and Anaerolineacear reached significant levels. Redundancy analysis at the genus level indicated that the available phosphate played a key role in the bacterial community distribution, and its role was negatively correlated with soil pH, organic matter content, alkali-hydrolyzable nitrogen, and available potassium contents. Interaction network analysis further demonstrated that greater diversity at the genus level existed in the SS network and formed a stable network. Additionally, the species of Mycobacterium , Cyanobacteria , and Rhodobiaceae are the key components that sustain the network stability. Seven clusters of orthologous groups exhibited significant differences between SS and CS. Moreover, 55 bacterial strains with distinct antagonistic activities to R. solancearum were isolated and identified.
Conclusions: Our findings indicate that the bacterial diversity and interaction network differed between the CS and SS samples, providing a good foundation in the study of bacterial wilt.

Published: March 2020

Abstract
Background: Sarcopenia and handgrip strength have been observed and correlated in association with hypertension among the old-age people. However, the results reported in different studies were inconsistent. In the current study, we conducted a systematic review and meta-analysis to reveal the significant association between sarcopenia, handgrip strength, and hypertension in older adults.
Methods: PubMed, MEDLINE, Cochrane Library, and EMBASE databases were searched from inception to 15 November, 2019 to retrieve the original research studies that addressed the association between sarcopenia, handgrip strength, and hypertension. All the relevant data were retrieved, analyzed, and summarized.
Results: 19 studies met the inclusion criteria and a total of 21301 participants were included in the meta-analysis. Eight eligible studies have reported the odd ratios (ORs) of hypertension and the ORs ranged from 0.41 to 4.38. When pooled the ORs together, the summarized ORs was 1.29 [95% confidence interval (CI) =1.00-1.67]. The summarized ORs for the Asian group 1.50 (95% CI=1.35-1.67) was significantly higher than that of Caucasian group 1.08 (95% CI=0.39-2.97). Eleven studies have provided the data on association between handgrip strength and hypertension. The overall ORs and 95% CI was 0.99 (95% CI=0.80-1.23), showing no significant association.
Conclusion: Sarcopenia was associated with hypertension, but no correlation was found between handgrip strength and hypertension in older adults.

Abstract
Background: The first month is the most crucial period for child survival. Neonatal mortality continues to remain high with little improvement over the years in Sub-Saharan Africa, including Ethiopia. This region shows the least progress in reducing neonatal mortality and continues to be a significant public health issue. In this study setting, the causes and predictors of neonatal death in the neonatal intensive care units are not well documented. Hence, this study aimed to determine the causes and predictors of neonatal mortality among infants admitted to neonatal intensive care units in eastern Ethiopia. Methods: A facility-based prospective follow-up study was conducted among neonates admitted to neonatal intensive care units in public hospitals in eastern Ethiopia from November 1 to December 30, 2018. Data were collected using a pre-tested structured questionnaire and a follow-up checklist. The main outcomes and causes of death were set by pediatricians and medical residents. Epi-Data 3.1 and Statistical Package for Social Sciences Version 25 software were used for data entry and analysis, respectively. Multivariable logistic regression was used to identify the predictors of facility-based neonatal mortality.Results: The proportion of facility-based neonatal mortality was 20%(95% CI:16.7-23.8%). The causes of death were complications of preterm birth (28.58%), birth asphyxia (22.45%), neonatal infection (18.36%), meconium aspiration syndrome (9.18%), respiratory distress syndrome (7.14%), and congenital malformation (4.08%). Low birth weight, preterm births, length of stay in the neonatal intensive care unit, low 5 minutes APGAR score, hyperthermia, and initiation of feeding were predictors of neonatal death among infants admitted to the neonatal intensive care units in public hospitals in eastern Ethiopia.Conclusions: The proportion of facility-based neonatal deaths was unacceptably high. The main causes of death were preventable and treatable. Hence, improving the timing and quality of antenatal care is essential for early detection, anticipating high-risk newborns, and timely interventions. Furthermore, early initiation of feeding and better referral linkage to tertiary health facilities could lead to a reduction in neonatal death in this setting.

Published: March 2020

Abstract
Background

Bronchiolitis is a clinical syndrome commonly encountered in practice, particularly among infants and young children. To investigate the prevalence of pathogens in hospitalized infants with bronchiolitis and study the relationship between the clinical characteristics and pathogens.

Methods

We investigated the respiratory specimens and clinical data of 1012 children with bronchiolitis who were treated at the Children’s Hospital of Soochow University between November 2011 and December 2018. The nasopharyngeal aspirates were examined by direct immunofluorescence assay or polymerase chain reaction (PCR) to detect viruses and by PCR and enzyme-linked immunosorbent assay to detect Mycoplasma pneumoniae (MP).

Results

Of the 1012 children with bronchiolitis, 842 (83.2%) were detected at least a pathogen. 614 (60.7%) had single viral infections, 91 (9.0%) had MP infections, 70 (6.9%) had multiple viral infections, and 67 (6.6%) had mixed viral and MP infection. The most common pathogens detected were respiratory syncytial virus (RSV) (44.4%), MP (15.6%), and human rhinovirus (HRV) (14.4%). RSV was the most common pathogen detected in children less than 6 months. Coinfection was detected in 13.5% (137/1012) of the children, but it was less common in children less than 6 months. The age of children with single virus infection was the youngest. Children with single virus infection had a higher proportion of oxygen therapy compared with single MP infection.

Conclusions

The most common pathogen detected in children with bronchiolitis is RSV, followed by MP and HRV. Co-infections lead to prolonged illness and worsening of the symptoms

Abstract
Background

For novel cancer treatments, effectiveness in clinical practice is not always aligned with clinical efficacy results. As such it is important to understand a treatment’s real-world effectiveness. We examined real-world population-based comparative effectiveness of second-line ipilimumab versus non-ipilimumab treatments (chemotherapy or targeted treatments).

Methods

We used a cohort of melanoma patients receiving systemic treatment for advanced disease since April 2005 from Ontario, Canada. Patients were identified from provincial drug databases and the Ontario Cancer Registry who received second-line ipilimumab from 2012 to 2015 (treated) or second-line non-ipilimumab treatment prior to 2012 (historical controls). Historical controls were chosen, to permit the most direct comparison to pivotal trial findings. The cohort was linked to administrative databases to identify baseline characteristics and outcomes. Kaplan-Meier curves and multivariable Cox regression models were used to assess overall survival (OS). Observed potential confounders were adjusted for using inverse probability of treatment weighting (IPTW).

Results

We identified 329 patients with MM who had received second-line treatments (189 treated; 140 controls). Patients receiving second-line ipilimumab were older (61.7 years vs 55.2 years) compared to historical controls. Median OS were 6.9 (95% CI: 5.4-8.3) and 4.95 (4.3-6.0) months for ipilimumab and controls, respectively. The crude 1-year, 2-year, and 3-year OS probabilities were 34.3% (27%-41%), 20.6% (15%-27%), and 15.2% (9.6%-21%) for ipilimumab and 17.1% (11%-23%), 7.1% (2.9%-11%), and 4.7% (1.2%-8.2%) for controls. Ipilimumab was associated with improved OS (IPTW HR=0.62; 95% CI: 0.49-0.78; p <0.0001).

Conclusions

This real-world analysis suggests second-line ipilimumab is associated with an improvement in OS for MM patients in routine practice.

Abstract
Background: Increased intestinal barrier permeability and subsequent gut microbial translocation are significant contributors to inflammatory non-AIDS comorbidities in people living with HIV (PLWH). Evidence in animal models have shown that markers of intestinal permeability and microbial translocation vary over the course of the day and are affected by food intake and circadian rhythms. However, daily variations of these markers are not characterized yet in PLWH. Herein, we assessed the variation of these markers over 24 hours in PLWH receiving antiretroviral therapy (ART) in a well-controlled environment. Methods: As in Canada, PLWH are predominantly men and the majority of them are now over 50 years old, we selected 11 men over 50 receiving ART with undetectable viremia for more than 3 years in this pilot study. Blood samples were collected every 4 hours over 24 hours before snacks/meals from 8:00 in the morning to 8:00 the next day. All participants consumed similar meals at set times, and had a comparable amount of sleep, physical exercise and light exposure. Plasma levels of bacterial lipopolysaccharide (LPS) and fungal (1→3)-β-D-Glucan (BDG) translocation markers, along with markers of intestinal damage fatty acid binding protein (I-FABP) and regenerating islet-derived protein-3α (REG3α) were assessed by ELISA or the fungitell assay.Results: Participants had a median age of 57 years old (range 50 to 63). Plasma levels of BDG and REG3α did not vary significantly over the course of the study. In contrast, a significant increase of LPS was detected between 12:00 and 16:00 (Z-score: -1.15 ± 0.18 vs 0.16 ± 0.15, p=0.02), and between 12:00 and 24:00 (-1.15 ± 0.18 vs 0.89 ± 0.26, p<0.001). The plasma levels of I-FABP at 16:00 (-0.92 ± 0.09) was also significant lower, compared to 8:00 the first day (0.48±0.26, p=0.002), 4:00 (0.73±0.27, p<0.001) or 8:00 on secondary day (0.88±0.27, p<0.001). Conclusions: Conversely to the fungal translocation marker BDG and the gut damage marker REG3α, time of blood collection matters for the proper evaluation for LPS and I-FABP as markers for the risk of inflammatory non-AIDS co-morbidities. These insights are instrumental for orienting clinical investigations in PLWH.

Published: March 2020

Abstract
Background
Anaemia is common in haemodialysis (HD) patients and associated with significant morbidity and mortality. Intravenous (IV) iron combined with erythropoiesis-stimulating agents (ESA) is the mainstay treatment of anaemia in these patients. The comparative efficacy and risk of adverse events with IV iron preparations have been assessed in only a few trials.

Methods
This was a retrospective observational study in 2 centres designed to compare the safety and efficacy of iron sucrose (IS-Venofer®) versus iron isomaltoside (IIM-Diafer®) in haemodialysis patients. The study included patients currently on dialysis and receiving Venofer who were switched to Diafer® and monitored for at least 12 months for each iron preparation.

Results
A total of 190 patients were included and had a mean age of 65.8 years (SD ± 15.5). Non-inferiority was confirmed with no change in mean haemoglobin per mg of iron administered over a 12-month period.
In total there were 41,295 prescriptions of iron isomaltoside and 14,685 of iron sucrose with no difference in the number of reported adverse events during the study period (7 each, none were severe).
There was a statistically significant effect on Hb over time after conversion, including after adjustment for multiple comparisons. There were significant improvements in ferritin over time, which remained at 6 months (P<0.01). The weekly iron dose was similar after adjustment (P=0.02). The EPO dose did not differ significantly after month 0 in patients switched to IIM.

Conclusions
This study demonstrates the comparative safety and efficacy of iron isomaltoside versus iron sucrose, with similar dosing schedules in dialysis patients. Iron isomaltoside is non-inferior to iron sucrose in maintaining Hb in patients on regular haemodialysis/haemodiafiltration with no difference in the number of reported adverse events.

Abstract
Background Chromium has been suggested playing a role in alleviating diabetes, insulin resistance and lipid anomalies, but the effect on metabolic syndrome (MetS) in humans remains controversial. Methods We conducted a matched case-control study in a Chinese population, involving 2,141 MetS cases and 2,141 healthy controls, which were 1:1 matched by age (±2 years) and sex. Plasma chromium was measured by inductively coupled plasma mass spectrometry. Results Plasma chromium levels were lower in MetS group than in control group (mean: 4.36 μg/L and 4.66 μg/L, respectively, P < 0.001), and progressively decreased with the number of MetS components ( P for trend < 0.001). After adjustment for potential confounding factors, the odds ratios (95% confidence intervals) for MetS across increasing quartiles of plasma chromium levels were 1 (reference), 0.84 (0.67-1.05), 0.76 (0.61-0.95), and 0.62 (0.49-0.78), respectively ( P for trend < 0.001). For the components of MetS (high waist circumference, high triglycerides and high blood glucose), the odds ratios (95% confidence intervals) of the highest quartiles were 0.77 (0.61-0.95), 0.67 (0.55-0.80), and 0.53 (0.44-0.64), respectively ( P for trend < 0.05). Conclusions Our results indicated that plasma chromium levels were inversely associated with MetS in Chinese adults. The association may be explained by the relations between plasma chromium levels and high waist circumference, and the triglycerides and blood glucose levels.
