Abstract
Introduction: Previous studies have identified a positive association between the inflammatory potential of the diet and hypertension. It is not known if BMI is an effect modifier for this association, nor if the association is dose-respondent. This study aimed to assess the association between the dietary inflammatory index (DII) and the risk of hypertension, and assess any effect modification from BMI.Methods: Data from the E3N cohort study, a French prospective population-based study initiated in 1990 was used. From the women in the study, we included those who completed a detailed diet history questionnaire, and who did not have prevalent hypertension or cardiovascular disease at baseline, resulting in 46,652 women. The adapted DII was assessed with data from the dietary questionnaire. Hypertension cases were self-reported and verified through a drug-reimbursement database. Cox proportional hazard models were used to calculate hazard ratios. Spline regression was used to determine any dose-respondent relationship.Results: During 884,267 person-years, 13,183 cases of incident hypertension were identified. The median DII in the population was slightly pro-inflammatory (DII = + 0.44). A highly pro-inflammatory diet (DII > 3.0) was associated with a slight increase in hypertension risk (HRQ1-Q5 = 1.07 [1.02: 1.13]). Evidence was observed for effect modification from BMI, with associations strongest amongst women in the 18.5 - 21.0 BMI range (HRQ1-Q5 = 1.17 [1.06: 1.29]). A weak dose-respondent relationship was observed.Conclusion: Evidence for a weak association between DII and hypertension was observed. Associations were stronger amongst healthy-lean women.
Glucose transporter GLUT1 influences Plasmodium berghei infection in Anopheles stephensi
Authors: Wang Mengfei , Wang Jingwen 
Published: June 2020

Abstract
Background: Sugar-feeding provides energy for mosquitoes. Facilitated glucose transporters (GLUTs) are responsible for the uptake of glucose in animals. However, knowledge of GLUTs function in Anopheles spp. is limited. Methods: Phylogenetic analysis of GLUTs in Anopheles stephensi was performed by the maximum likelihood and Bayesian inference methods. The spatial and temporal expression patterns of four Asteglut genes were analyzed by qPCR. The function of Asteglut1 was examined using a dsRNA-mediated RNA interference method. Transcriptome analysis was used to investigate the global influence of Asteglut1 on mosquito physiology.Results: We identified 4 glut genes, Asteglut1, Asteglutx, Asteglut3 and Asteglut4 in An. stephensi. Asteglut1, Asteglut3 and Asteglut4 were mainly expressed in the midgut. Plasmodium berghei infection differentially regulated the expression of Asteglut genes with significant downregulation of Asteglut1 and Asteglut4, while upregulation of Asteglutx. Only knocking-down Asteglut1 facilitated Plasmodium berghei infection in An. stephensi. This might be due to the accumulation of glucose prior to blood-feeding in dsAsteglut1-treated mosquitoes. Our transcriptome analysis revealed that knockdown of Asteglut1 differentially regulated expression of genes associated with multiple functional clusters, especially those related to detoxification and immunity. The dysregulation of multiple pathways might contribute to the increased P. berghei infection. Conclusions: Our study shows that Asteglut1 participates in defense against P. berghei in An. stephensi. The regulation of Asteglut1 on vector competence might through modulating multiple biological processes, such as detoxification and immunity.

Abstract
Background: Low and middle-income countries have growing older populations and could benefit from the use of multi-domain geriatric assessments in overcoming the challenge of providing quality health services to older persons. This paper reports on the outcomes of a study carried out in Cape Town, South Africa on the validity of the interRAI Check-Up Self-Report instrument, a multi-domain assessment instrument designed to screen older persons in primary health settings. This is the first criterion validity study of the instrument. The instrument is designed to identify specific health problems and needs, including psychosocial or cognition problems and issues related to functional decline. The interRAI Check-Up Self-Report is designed to be compatible with the clinician administered instruments in the interRAI suite of assessments, but the validity of the instrument against clinician ratings has not yet been established. We therefore sought to establish whether community health workers, rather than trained healthcare professionals could reliably administer the self-report instrument to older persons.Methods: We evaluated the criterion validity of the self-report instrument through comparison to assessments completed by a clinician assessor. A total of 112 participants, aged 60 or older were recruited from 7 seniors clubs in Khayelitsha, Cape Town. Each participant was assessed by one of two previously untrained, non-healthcare personnel using the Check-Up Self-report version and again by a trained assessor using the clinician version of the interRAI Check-Up within 48 hours. Our analyses focused on the degree of agreement between the self-reported and clinician-rated versions of the Check-Up based on the simple or weighted kappa values for the two types of ratings. Binary variables used simple kappas, and ordinal variables with three or more levels were examined using weighted kappas with Fleiss-Cohen weights.Results: Based on Cohen’s Kappa values, we were able to establish that high levels of agreement existed between clinical assessors and lay interviewers, indicating that the instrument can be validly administered by community health workers without formal healthcare training. 13% of items had kappa values ranging between 0.10 and 0.39; 51% of items had kappa values between 0.4 and 0.69; and 36% of items had values of between 0.70 and 1.00Conclusion: Our findings indicate that there is potential for the Check-Up Self-Report instrument to be implemented in under-resourced health systems such as South Africa’s.
What do we know about physical activity interventions in vocational education and training? A systematic review

Published: June 2020

Abstract
Background: Although the health benefits of physical activity (PA) are well known, young people’s level of PA is often insufficient and tends to decline in adolescence. Numerous studies have investigated the effectiveness of PA-promoting interventions among young people, but none have reviewed the effectiveness of PA interventions in the vocational education and training (VET) setting. This systematic review aims to (1) synthesize and review the available literature on PA-promoting interventions in VET and (2) examine the effects of these interventions on PA-related outcomes such as PA level, physical fitness, physiological parameters, or psychological factors. Methods: Five electronic databases were searched for studies involving adolescents aged 15 to 20 years that took place in VET settings and evaluated the effects of interventions with a PA component on PA-related outcomes such as PA level, physical fitness, physiological parameters, or psychological factors. The screening process and the quality assessment were conducted by two independent reviewers; data extraction was conducted by one reviewer and verified by another. Results: The literature search identified 18,959 articles and 11,282 unique records. After the screening process, nine studies, all coming from European or Asian countries, met the pre-defined eligibility criteria and were included in qualitative analyses. All but two studies reported significant improvements for at least one PA-related outcome. The interventions substantially differed in their development approaches (top-down vs. bottom-up approaches), complexity (multi- vs. single-component), and addressed behavior (multi-behavioral vs. single-behavioral). The most conspicuous finding was that bottom-up approaches tend to improve outcomes at the psychological level and top-down approaches at the physical level. Regarding the interventions’ complexity and addressed behavior, we did not reveal any conclusive results.Conclusion: This systematic review highlights the varying effects of PA-promoting interventions in VET. Nevertheless, heterogeneous effects, overall weak study quality and availability of studies only from two continents limited our ability to draw clear conclusions about the potentially most effective intervention strategies. Therefore, future research should focus on high-quality studies with long-term follow-ups to make recommendations for practical use. Trial registration: PROSPERO CRD42018109845

Published: June 2020

Abstract
Background: Posterior cruciate ligament (PCL) avulsion fracture of tibia is an uncommon but serious complication during primary cruciate retaining total knee arthroplasty (TKA). The first objective of this report was to conduct a retrospective cohort study to investigate the incidence and potential risk factors of PCL avulsion fracture in primary cruciate-retaining TKA. The second objective was to assess the functional outcomes of the knee after reduction of PCL avulsion fracture.Methods: From January 2014 to January 2016, 56 patients who experienced PCL avulsion fracture of tibia in primary cruciate-retaining TKA were included in study group. Patients in this group underwent reduction of avulsion fracture. In this period, we selected 224 patients (control group) for comparison. Patients in this group also underwent the same TKA but no PCL avulsion fracture occurred. Range of motion of the knee and Knee Society Scores were assessed. The forgotten joint score was used to analyze the ability to forget the joint. Differences were considered statistically significant at p < 0.05.Results: In our series, the incidence of PCL avulsion fracture was 4.6%. There was no significant differences (p > 0.05) with regard to preoperative or postoperative range of motion of the knee, final 4 year mean clinical score in study and control groups 92.4 ± 2.7 and 93.6 ± 1.9, respectively, and mean functional scores of 85.1 ± 1.8 and 87.1 ± 1.2, respectively.Conclusions: The incidence of PCL avulsion fracture of tibia is relatively high. Older age and female gender were two risk factors of fracture in primary cruciate-retaining TKA. Reduction of PCL avulsion fracture with high-strength line can achieve good stability and function of the knee.

Abstract
Background: The rate of diagnosis of advanced lung adenocarcinoma must be improved. In this study, we compared the detection rates of EGFR-tyrosine kinase inhibitor-sensitizing mutations (mEGFRs) in bronchial washing fluid (BWF) and the plasma of patients with lung adenocarcinoma using the tissue genotype as the standard reference.Methods: Paired blood and BWF specimens were collected from 73 patients with lung cancer. The tumor EGFR mutation status was determined by genotyping of the plasma and BWF samples using droplet digital PCR (ddPCR).Results: The study cohort included 26, 10, 10, and 27 patients with stage I, II, III, and IV disease. Of the 73 cases, 35 had a wild-type EGFR, and 19 had the L858R substitution and exon 19 deletion mutations. The areas under the receiver operator characteristic curves for sensitivity vs. specificity of ddPCR were 0.895 [95% confidence interval (CI): 0.822–0.969] for BWF and 0.686 (95% CI: 0.592–0.780) for plasma (p < 0.001). The fractional abundance was higher in BWF of the mEGFR-positive cases than in the plasma (p = 0.004), facilitating easy threshold setting and discrimination between mEGFR-positive and negative cases. When genotyping results obtained using plasma and BWF were compared for early lung cancer (stages I–IIIA), the diagnostic yields were significantly higher for BWF ddPCR, and the same tendency was observed for the advanced stages, suggesting that the BWF data may reflect the genotype status in early-stage patients.Conclusions: The mEGFR genotyping results obtained using BWF showed a higher diagnostic efficacy than did those obtained using the plasma. Thus, BWF-based genotyping may be a useful substitute for that using plasma in lung cancer.

Published: June 2020

Abstract
Background: Several studies indicated that dietary organic selenium (Se) usually absorbed better than an inorganic source, with high retention and bioavailability. Dietary Se as an antioxidant element affects the immune system and hematological status in animals. Therefore, the aim of this study was to evaluate the effect of dietary supplementation of bacterial selenium as an organic source on hematology, immunity response, selenium retention, and gut morphology in broiler chickens. Results: The present results revealed that supplementation of inorganic Se was associated with the lowest level of RBC, HB, and PCV with significant difference than ADS18-Se. In the starter stage, both T2 and T5 were associated with the significantly highest IgG level compared to the basal diet, while all supplemented groups showed higher IgM levels compared to the control group. In the finisher phase, all Se supplemented groups showed significant (P ˂ 0.05) increases in IgG, IgA, and IgM levels compared to T1. Birds fed bacterial-Se showed high intestinal villus height and better Se retention more than sodium selenite. The organic selenium of ADS18 had a superior action in improving Se retention compared to ADS1 and ADS2 bacterial Se. Conclusion: Bacterial organic Se had a beneficial effect on the villus height of small intestine led to high Se absorption and retention. Thus, it caused a better effect of Se on hematological parameters and immunity response.

Authors: Lawrie Steven Alan , Lawrie Angus , Vertullo Christopher 
Published: June 2020

Abstract
Background

Meniscal repair device deployment failure is a recognised complication of all-inside meniscal repair with subsequent risk of patient harm. The Fast-Fix device has undergone design changes to reduce deployment failure since its introduction in 2001.

Purpose

The purpose of this study was to assess the incidence and mechanism of intra-operative deployment failure of the 3 rd generation Fast-fix 360™ (Smith & Nephew, Andover, USA) device.

Method

Data was prospectively collected for 106 consecutive all-inside meniscal repairs undertaken with the Fast-fix 360™ device. Patient demographics, mechanism of failure, site and type of repair were recorded.

Results

20 deployment failures occurred in 423 Fast-fix 360™ deployments, an incidence of 4.72%. Deployment failure occurred in 19 of 109 patients an incidence of 17.43%. Six different failure mechanisms occurred; anchor exiting device without trigger being initiated, anchors not holding in meniscus, both anchors simultaneously exiting device and braided suture failing. The most common failure mechanism was failure of the second anchor not holding in the meniscus.

Average cost of device failure was $75 per patient.

Conclusion

Despite design modification, deployment failure still occurs with similar modes top to the original design.

Published: June 2020

Abstract
Background: The ability of blood feeding arthropods to successfully acquire and transmit pathogens of medical and veterinary importance has been shown to be interfered or enhanced by the arthropod’s native microbiome. Mosquitoes transmit bacteria, viruses, protozoan and filarial nematodes, majority of which contributes to the 17% of infectious disease cases worldwide. Dirofilaria immitis, a mosquito transmitted filarial nematodes of dogs and cats, is vectored by several mosquito species including Aedes aegypti.Methods: In this study, we investigated the impact of D. immitis colonization on the microbiome of laboratory reared female A. aegypti. Metagenomic analysis of the V3-V4 variable region of the microbial 16SRNA was used for identification of the microbial differences down to species level.Results: We generated a total of 1068 OTUs representing 16 phyla, 181 genera and 271 bacterial species. Overall, in order of abundance, Proteobacteria, Bacteroidetes, Actinobacteria and Firmicutes were the most represented phylum with D. immitis infected mosquitoes having more of Proteobacteria (71%) than uninfected mosquitoes (56.9%). An interesting finding in this study is the detection of Klebsiella oxytoca in relatively similar abundance in infected and uninfected mosquitoes, suggesting a possible endosymbiotic relationship. It has been previously shown to indirectly compete for nutrients with fungi on the domestic housefly eggs and larva. While D. immitis colonization has no effect on the overall species richness, we identified significant differences in the composition of selected bacteria genus and phylum between the two groups. We also reported distinct compositional and phylogenetic differences in the individual bacteria species when commonly identified bacteria were compared.Conclusions: In conclusion, this is the first study to the best of our knowledge to understand the impact of a filarial infection on the microbiome of its mosquito vector. Further studies is required to identify bacteria species that could play an important role in the mosquito biology. While the microbiome composition of A. aegypti mosquito have been previously reported, our study shows that in an effort to establish itself, a filarial nematode modifies and alters the overall microbial diversity within its mosquito host.

Abstract
Background: Identification of people living with HIV is key in HIV prevention and control. Partner Notification service is a World Health Organization backed strategy of reaching out to sexual partners of people diagnosed with HIV for HIV testing. However, its adoption and success rate in Kenya remains unknown.Methods: A cross sectional facility based study was undertaken in five purposely selected health facilities in Gatanga Sub county, Muranga County, Kenya. A retrospective review of patient medical records data for HIV positive index clients and their Sexual Partners conducted. Census approach was applied to extract data for study subjects from Partner Notification Services registers for the period covering January 2017 to August 2018. Epi Info software was used for data analysis.Results: A total of 183 index clients were offered Partner notification services. The mean age of the indexed clients studied was 39(SD ±13.1). Females comprised 64 % of clients studied. Of the 183 indexed clients, 89% accepted the services and elicited 216 sexual partners for tracing. The ratio of elicited sexual partners to index client was 1.3:1. Out of the 216 sexual partners, 77% were reached and tested. A total of 46 [32%] of the sexual partners elicited and traced, tested HIV positive. The most preferred approaches were provider referral (51%) and contract referral (45%). Dual referral (4%) was the least preferred approach. Conclusions: Assisted Partner notification services is acceptable and an effective strategy of increasing HIV case identification and raising awareness to exposed sexual partners in low resource countries.

Abstract
Background Prader–Willi syndrome (PWS) is a neurodevelopmental disorder characterized by multiple respiratory, cognitive, endocrine, and behavioral symptoms, such as central apnea, intellectual disabilities, exaggerated stress responses, and temper tantrums. The locus coeruleus noradrenergic system (LC-NE) modulates a diverse range of behaviors, including arousal, learning, pain modulation, and stress-induced negative affective states, which are possibly correlated with the pathogenesis of PWS phenotypes. Therefore, we evaluated the LC-NE neuronal activity of necdin-deficient mice, an animal model of PWS. Methods Heterozygous necdin-deficient mice (B6.Cg-Ndn tm1ky ) were bred from wild-type (WT) females to generate WT (+m/+p) and heterozygotes (+m/−p) animals, which were examined of LC-NE neuronal activity, developmental reflexes and plethysmography. Results On slice electrophysiology, LC-NE neurons of Ndn tm1ky mice with necdin deficiency showed significantly decreased spontaneous activities and impaired excitability, which was mediated by enhanced A-type voltage-dependent potassium currents. Ndn tm1ky mice also exhibited the neonatal phenotypes of PWS, such as hypotonia and blunt respiratory responses to hypercapnia. Conclusions LC-NE neuronal firing activity decreased in necdin-deficient mice, suggesting that LC, the primary source of norepinephrine in the central nervous system, is possibly involved in PWS pathogenesis.
