Body fat assessment in youth with overweight or obesity by an automated bioelectrical impedance analysis device, in comparison with the dual-energy x-ray absorptiometry: a cross sectional study
Authors: Samouda Hanen , Langlet Jérémie 
Published: August 2022

AbstractBackgroundBioelectrical impedance analysis (BIA) is a widely used method to assess total body fat (TBF) depots characterising obesity. Automated BIA devices provide an inexpensive and easy assessment of TBF, making them widely available to the general public and healthcare providers without specific qualification to assess body composition. The equations included in the automated BIA devices have been developed in very few specific populations, which means that they are not suitable to assess TBF for everyone and need to be validated before use in other populations.The aimof the present work is to evaluate the accuracy of the automated BIA device Tanita® BC-532 in youth of White European ethnicity, compared with the dual-energy x-ray absorptiometry (DEXA), gold standard measurement of TBF.MethodsTotal body fat percentage (TBF%) was measured with the BIA device Tanita® BC-532 and DEXA (Hologic® QDR4500W) in 197 youth of White European ethnicity (N = 104 girls), 7-17 years old, and visiting theDiabetes & Endocrinology Care Paediatrics Clinic, Centre Hospitalier de Luxembourg,for overweight or obesity management.ResultsTBF% evaluated with BIA was significantly correlated with TBF% measured with DEXA in both boys (rPearson = 0.617) and girls (rPearson = 0.648) (p <  10− 4). However, the residual mean between the assessment of TBF% by BIA and by DEXA [TBFBIA(%)-TBFDEXA(%)] is extremely high (mean ± standard deviation = 10.52% ± 5.22% in boys, respectively 9.96% ± 4.40% in girls). The maximal absolute residual value is also very high, about 24% in both genders.ConclusionsThe automated BIA device Tanita® BC-532 appears to be not accurate to assess total body fat in youth with overweight or obesity. There is a need to calibrate the BIA device before its use in the populations where it was not previously validated.

Abstract
Background
Existing evidence marked a prevalent use of Complementary and Alternative Medicine (CAM) therapies in Lebanon that is concomitant with low rates of disclosure to health care providers and limited knowledge among the general public of safety and side effects of CAM use.

Objectives
To examine the perspectives of Lebanese CAM users, CAM providers, and health care providers (HCPs) regarding their understanding of CAM and of the Push and Pull factors that drive its use.

Methods
A qualitative research study was conducted using in-depth interviews, targeting Lebanese adults (CAM users; 18-65 years) (n=14), CAM providers such as yoga instructors, owners of CAM product outlets, herbalists, and religious figures (n=13); and HCPs including physicians, nurses, dietitians, and pharmacists (n=14). The topic guide covered, in addition to the understanding of CAM, the Push and Pull factors driving CAM use. The adults were recruited by convenient sampling, and CAM providers and HCPs using a purposive sampling approach. Interviews were audiotaped, transcribed, and translated into English. Analysis was performed using a qualitative thematic approach. Similarities and differences in the perceptions of the participants with regards to factors that influence CAM use were charted and contrasted, using a triangulated approach.

Results
The three study groups exhibited a similar understanding of CAM, referring to non-conventional therapies used to prevent/treat diseases or to enhance wellbeing. CAM users and CAM providers identified “distrust in HCPs”, “lack of patient-centered care in CM”, and “limitations and side effects of CM” as important Push factors. All study groups highlighted the limited CAM knowledge of HCPs as a main reason for the lack of patient-centered care. All three groups also underscored the affordability and the social and cultural support for CAM as main enablers of its prevalent use. Unlike HCPs who were skeptical about the safety and effectiveness of CAM, CAM users and CAM providers indicated that most of CAM therapies are safe and efficient.

Conclusions
The triangulation of perspectives (CAM users, CAM providers, and HCPs) in this study allowed a comprehensive appraisal of CAM use and its drivers. Improving the HCPs’ CAM-related knowledge, promoting patient-centered care and fostering an open dialogue between HCPs and CAM providers are among the recommendations of the study.

Authors: Veatch Olivia J. , Steinle Jacob , Hossain Waheeda A. , Butler Merlin G. 
Published: August 2022

Abstract
Background
Heritable connective tissue disorders (HCTDs) consist of heterogeneous syndromes. The diagnosis of HCTDs is aided by genomic biotechnologies (e.g., next-generation sequencing panels) facilitating the discovery of novel variants causing disease.

Methods
Detailed clinical exam data and CLIA-approved genetic testing results from next generation sequencing of 74 genes known to play a role in HCTDs were manually reviewed and analyzed in one hundred consecutive, unrelated patients with phenotypic features indicative of a HCTD referred over a 3.5-year period (2016–2020) to a specialized academic genetics clinic. The prevalence of symptoms was evaluated in the context of genetic variants. We also determined if symptoms among different organ systems were related and performed latent class analysis to identify distinct groups of patients based on symptomatology.

Results
In the cohort of 100 consecutive, unrelated individuals there were four pathogenic, six likely pathogenic and 35 classified potentially pathogenic variants of unknown clinical significance. Patients with potentially pathogenic variants exhibited similar symptom profiles when compared to patients with pathogenic/likely pathogenic variants in the same genes. Although results did not meet a multiple testing corrected threshold, patients with connective tissue symptoms had suggestive evidence of increased odds of having skin (odds ratio 2.18, 95% confidence interval 1.12 to 4.24) and eye symptoms (odds ratio 1.89, 95% confidence interval 0.98 to 3.66) requiring further studies. The best performing latent class analysis results were identified when dividing the dataset into three distinct groups based on age, gender and presence or absence of symptoms in the skeletal, connective tissue, nervous, gastrointestinal and cardiovascular systems. These distinct classes of patients included individuals with: (1) minimal skeletal symptoms, (2) more skeletal but fewer connective tissue, nervous or gastrointestinal symptoms and (3) more nervous system symptoms.

Conclusions
We used novel approaches to characterize phenotype-genotype relationships, including pinpointing potentially pathogenic variants, and detecting unique symptom profiles in patients with features of HCTDs. This study may guide future diagnosis and disease/organ system monitoring with continued improvement and surveillance by clinicians for patients and their families.
IDO/kynurenine pathway in cancer: possible therapeutic approaches
Authors: Abd El-Fattah Eslam E. 
Published: August 2022

AbstractCancer is one of the leading causes of death in both men and women worldwide. One of the main changes associated with cancer progression, metastasis, recurrence, and chemoresistance is the change in the tumor immune microenvironment, especially immunosuppression. Cancer immunosuppression appears in multiple forms, such as inhibition of immuno-stimulant cells with downregulation of immuno-stimulant mediators or through stimulation of immuno-suppressive cells with upregulation of immunosuppressive mediators. One of the most immunosuppressive mediators that approved potency in lung cancer progression is indoleamine 2,3-dioxygenase (IDO) and its metabolite kynurenine (Kyn). The current review tries to elucidate the role of IDO/Kyn on cancer proliferation, apoptosis, angiogenesis, oxidative stress, and cancer stemness. Besides, our review investigates the new therapeutic modalities that target IDO/Kyn pathway and thus as drug candidates for targeting lung cancer and drugs that potentiate IDO/Kyn pathway and thus can be cancer-promoting agents.

AbstractBackgroundPrenatal vitamin use is recommended before and during pregnancies for normal fetal development. Prenatal vitamins do not have a standard formulation, but many contain calcium, folic acid, iodine, iron, omega-3 fatty acids, zinc, and vitamins A, B6, B12, and D, and usually they contain higher concentrations of folic acid and iron than regular multivitamins in the US Nutrient levels can impact epigenetic factors such as DNA methylation, but relationships between maternal prenatal vitamin use and DNA methylation have been relatively understudied. We examined use of prenatal vitamins in the first month of pregnancy in relation to cord blood and placenta DNA methylation in two prospective pregnancy cohorts: the Early Autism Risk Longitudinal Investigation (EARLI) and Markers of Autism Risk Learning Early Signs (MARBLES) studies.ResultsIn placenta, prenatal vitamin intake was marginally associated with −0.52% (95% CI −1.04, 0.01) lower mean array-wide DNA methylation in EARLI, and associated with −0.60% (−1.08, −0.13) lower mean array-wide DNA methylation in MARBLES. There was little consistency in the associations between prenatal vitamin intake and single DNA methylation site effect estimates across cohorts and tissues, with only a few overlapping sites with correlated effect estimates. However, the single DNA methylation sites withp-value < 0.01 (EARLI cordnCpGs = 4068, EARLI placentanCpGs = 3647, MARBLES cordnCpGs = 4068, MARBLES placentanCpGs = 9563) were consistently enriched in neuronal developmental pathways.ConclusionsTogether, our findings suggest that prenatal vitamin intake in the first month of pregnancy may be related to lower placental global DNA methylation and related to DNA methylation in brain-related pathways in both placenta and cord blood.

Abstract
Background
Imprinting Control Regions (ICRs) are CpG-rich sequences acquiring differential methylation in the female and male germline and maintaining it in a parental origin-specific manner in somatic cells. Despite their expected high mutation rate due to spontaneous deamination of methylated cytosines, ICRs show conservation of CpG-richness and CpG-containing transcription factor binding sites in mammalian species. However, little is known about the mechanisms contributing to the maintenance of a high density of methyl CpGs at these loci.

Results
To gain functional insights into the mechanisms for maintaining CpG methylation, we sought to identify the proteins binding the methylated allele of the ICRs by determining the interactors of ZFP57 that recognizes a methylated hexanucleotide motif of these DNA regions in mouse ESCs. By using a tagged approach coupled to LC–MS/MS analysis, we identified several proteins, including factors involved in mRNA processing/splicing, chromosome organization, transcription and DNA repair processes. The presence of the post-replicative mismatch-repair (MMR) complex components MSH2 and MSH6 among the identified ZFP57 interactors prompted us to investigate their DNA binding profile by chromatin immunoprecipitation and sequencing. We demonstrated that MSH2 was enriched at gene promoters overlapping unmethylated CpG islands and at repeats. We also found that both MSH2 and MSH6 interacted with the methylated allele of the ICRs, where their binding to DNA was mediated by the ZFP57/KAP1 complex.

Conclusions
Our findings show that the MMR complex is concentrated on gene promoters and repeats in mouse ESCs, suggesting that maintaining the integrity of these regions is a primary function of highly proliferating cells. Furthermore, the demonstration that MSH2/MSH6 are recruited to the methylated allele of the ICRs through interaction with ZFP57/KAP1 suggests a role of the MMR complex in the maintenance of the integrity of these regulatory regions and evolution of genomic imprinting in mammalian species.

Published: August 2022

AbstractBackgroundMesenchymal stem cells (MSCs) have a great potential ability for endothelial differentiation, contributing to an effective means of therapeutic angiogenesis. Placenta-derived mesenchymal stem cells (PMSCs) have gradually attracted attention, while the endothelial differentiation has not been fully evaluated in PMSCs. Metabolism homeostasis plays an important role in stem cell differentiation, but less is known about the glycometabolic reprogramming during the PMSCs endothelial differentiation. Hence, it is critical to investigate the potential role of glycometabolism reprogramming in mediating PMSCs endothelial differentiation.MethodsDil-Ac-LDL uptake assay, flow cytometry, and immunofluorescence were all to verify the endothelial differentiation in PMSCs. Seahorse XF Extracellular Flux Analyzers, Mito-tracker red staining, Mitochondrial membrane potential (MMP), lactate secretion assay, and transcriptome approach were to assess the variation of mitochondrial respiration and glycolysis during the PMSCs endothelial differentiation. Glycolysis enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) was considered a potential modulator for endothelial differentiation in PMSCs by small interfering RNA. Furthermore, transwell,in vitroMatrigel tube formation, andin vivoMatrigel plug assays were performed to evaluate the effect of PFKFB3-induced glycolysis on angiogenic capacities in this process.ResultsPMSCs possessed the superior potential of endothelial differentiation, in which the glycometabolic preference for glycolysis was confirmed. Moreover, PFKFB3-induced glycometabolism reprogramming could modulate the endothelial differentiation and angiogenic abilities of PMSCs.ConclusionsOur results revealed that PFKFB3-mediated glycolysis is important for endothelial differentiation and angiogenesis in PMSCs. Our understanding of cellular glycometabolism and its regulatory effects on endothelial differentiation may propose and improve PMSCs as a putative strategy for clinical therapeutic angiogenesis.
An (un)healthy social dilemma: a normative messaging field experiment with flu vaccinations
Authors: Mussio Irene , de Oliveira Angela C. M. 
Published: August 2022

Abstract
Background
Influenza seasons can be unpredictable and have the potential to rapidly affect populations, especially in crowded areas. Prior research suggests that normative messaging can be used to increase voluntary provision of public goods, such as the influenza vaccine. We extend the literature by examining the influence of normative messaging on the decision to get vaccinated against influenza.

Methods
We conduct a field experiment in conjunction with University Health Services, targeting undergraduate students living on campus. We use four posters, randomized by living area clusters to advertise flu vaccination clinics during the Fall. The wording on the posters is varied to emphasize the individual benefits of the vaccine, the social benefits of the vaccine or both benefits together. We collect survey data for those vaccinated at the vaccination clinics, and for those not vaccinated via an online survey.

Results
We find that any normative message increases the percentage of students getting the flu vaccine compared with no message. In terms of the likelihood of getting the flu vaccine, emphasizing both the individual and social benefits of vaccination has the largest increase in the vaccination rate (19–20 percentage point increase). However, flu vaccinations did not reach the herd immunity threshold (70% of students vaccinated).

Conclusions
This study provides evidence that there is a pro-social component that is relevant in individual vaccination decisions which should be accounted for when designing vaccination campaigns. The results of this normative, pro-social messaging experiment could be extended to other at-risk communities where the number of background risks is much larger. This is especially relevant nowadays, as other seasonal vaccines are being rolled out and younger adults are the ones with the lowest uptake.

AbstractPlant growth-promoting rhizobacteria are a type of beneficial bacteria which inhabit in the rhizosphere and possess the abilities to promote plant growth. Pseudomonas putida LWPZF is a plant growth-promoting bacterium isolated from the rhizosphere soil of Cercidiphyllum japonicum. Inoculation treatment with LWPZF could significantly promote the growth of C. japonicum seedlings. P. putida LWPZF has a variety of plant growth-promoting properties, including the ability to solubilize phosphate, synthesize ACC deaminase and IAA. The P. putida LWPZF genome contained a circular chromosome (6,259,530 bp) and a circular plasmid (160,969 bp) with G+C contents of 61.75% and 58.25%, respectively. There were 5632 and 169 predicted protein-coding sequences (CDSs) on the chromosome and the plasmid respectively. Genome sequence analysis revealed lots of genes associated with biosynthesis of IAA, pyoverdine, ACC deaminase, trehalose, volatiles acetoin and 2,3-butanediol, 4-hydroxybenzoate, as well as gluconic acid contributing phosphate solubilization. Additionally, we identified many heavy metal resistance genes, including arsenate, copper, chromate, cobalt-zinc-cadmium, and mercury. These results suggest that P. putida LWPZF shows strong potential in the fields of biofertilizer, biocontrol and heavy metal contamination soil remediation. The data presented in this study will allow us to better understand the mechanisms of plant growth promotion, biocontrol, and anti-heavy metal of P. putida LWPZF.
Puhals: Outlining the Dynamics of Labour and Hired Herding among the Gaddi Pastoralists of India

Published: August 2022

AbstractPastoral practices throughout the world are in a state of flux, and Gaddi pastoralism in India’s Western Himalayas is no exception. Often in literature and common parlance, these practices are predicted to end with the current generation of practising pastoralists. For Gaddi, an agro-pastoral community located in the hill state of Himachal Pradesh in India, these gloomy predictions have remained persistent over decades. Irrespective of these claims, pastoralism continues to remain a viable livelihood option for many within the community even today. However, the institutional dynamics in which these practices are embedded have undergone several changes.In this paper, we discuss the changes in Gaddi pastoralism and its resilience by stressing a critical aspect of labour, often referred to as puhals in their vernacular dialect. Out of the various contextual meanings, we adopt the applied translation of this term as hired herders to understand their role in the larger socio-ecological system amidst the on-going livelihood shifts and declining interest among the Gaddi youth to pursue pastoralism. The data presented in this paper was collected through ethnographic fieldwork conducted during 2018–2019 at Bharmour region of Chamba district in Himachal Pradesh, India. Qualitative tools including in-depth interviews, focus group discussions and participant observations were administered. We discuss various aspects of puhal practices among the Gaddis including their recruitment process, need for hiring, involved negotiations over remunerations, skill sets and access to the resources, to highlight the institutional dynamism. Our findings suggest that hiring herders remains a crucial adaptation for the continuation and sustenance of pastoral practices that are facing contingent external pressures. It also facilitates transmission of local knowledge, livelihood and income diversification, accumulation of wealth, social mobility and cultural continuity. We conclude that hired herding, in the face of increasing labour shortages among the Gaddis, offers an innovative proposition to halt the decline in pastoralism and shape its future.

AbstractBackground/AimsTick-borne encephalitis (TBE) is a disease affecting the central nervous system. Over the last decade, the incidence of TBE has steadily increased in Europe and Asia despite the availably of effective vaccines. Up to 50% of patients after TBE suffer from post-encephalitic syndrome that may develop into long-lasting morbidity. Altered sleep–wake functions have been reported by patients after TBE. The mechanisms causing these disorders in TBE are largely unknown to date. As a first step toward a better understanding of the pathology of TBEV-inducing sleep dysfunctions, we assessed parameters of sleep structure in an established infant rat model of TBE.Methods13-day old Wistar rats were infected with 1 × 106FFU Langat virus (LGTV). On day 4, 9, and 21 post infection, Rotarod (balance and motor coordination) and open field tests (general locomotor activity) were performed and brains from representative animals were collected in each subgroup. On day 28 the animals were implanted with a telemetric EEG/EMG system. Sleep recording was continuously performed for 24 consecutive hours starting at day 38 post infection and visually scored for Wake, NREM, and REM in 4 s epochs.ResultsAs a novelty of this study, infected animals showed a significant larger percentage of time spend awake during the dark phase and less NREM and REM compared to the control animals (p < 0.01 for all comparisons). Furthermore, it was seen, that during the dark phase the wake bout length in infected animals was prolonged (p = 0.043) and the fragmentation index decreased (p = 0.0085) in comparison to the control animals. LGTV-infected animals additionally showed a reduced rotarod performance ability at day 4 (p = 0.0011) and day 9 (p = 0.0055) and day 21 (p = 0.0037). A lower locomotor activity was also seen at day 4 (p = 0.0196) and day 9 (p = 0.0473).ConclusionOur data show that experimental TBE in infant rats affects sleep–wake behavior, leads to decreased spontaneous locomotor activity, and impaired moto-coordinative function.
