Abstract
Background: Little attention has been paid to whether snoring frequency is associated with body composition in menopausal women, particularly in China. This study objected to investigate the association between self-reported snoring and body composition in (peri-post) menopausal Chinese women as well as metabolic indicators.Methods: This cross-sectional study enrolled 715 participants aged 40-67 years from the Menopause Clinic in the Shanghai Sixth People’s Hospital. Participants were categorized into four subgroups stratified by self-reported snoring frequency: never, rarely (<1 night per week), occasionally (1-2 nights per week), regularly (≥3 nights per week), while body composition was measured using bioelectrical impedance analysis (BIA).Besides, blood sample were collected to test the glycolipid indicators. Results: In our sample of investigation, regular snoring (≥3 nights per week) was found to be an independent risk factor for higher fat mass (total, upper limbs, trunk), with the highest risk of 2.4 times for fat mass of trunk after adjusting for metabolic confounders(p=0.003). Meanwhile, regular snoring was independently associated with higher fat mass (total and each segment) only in menopausal transition (p=0.023).Conclusions: We suggested that self-reported regular snoring may be taken as a simple alternative to predict higher fat mass (≥17.11kg, upper quartile) in menopausal women. Similarly, body composition should be attached to the great importance to those who in menopausal transition in order to help to prevent obstructive sleep apnea (OSA).

Authors: Guerin Suzanne , Kiernan Gemma , Courtney Eileen , McQuillan Regina , Ryan Karen 
Published: June 2020

Abstract
Background: The aim of this study was to explore expert professionals’ opinions on service provision to children under six with life-limiting neurodevelopmental disabilities (LLNDD), including the goals of care and the integration and coordination of palliative care in general and specialist services. Methods: A Delphi design was used with three survey questionnaire rounds, one open-ended and two closed response rounds. Primary data collected over a six-month period from expert professionals with five years’ (or more) experience in pediatric, intellectual disability and/or palliative care settings. Ratings of agreement and prioritization were provided with agreement expressed as a median (threshold = 80%) and consensus reported as interquartile ranges. Stability was measured using non-parametric tests. Results: Primary goals of care were achievement of best possible quality of life, effective communication and symptom management. Service integration and coordination were considered inadequate, and respondents agreed that areas of deficiency included palliative care. Improvement strategies included a single care plan, improved communication and key worker appointments. Conclusions: The findings suggest that services do not serve this group well with deficiencies in care compounded by a lack of information on available services and sub-optimal communication between settings. Further research is needed to develop an expert-based consensus regarding the care of children with LLNDD.

Abstract
Background: Closely related species of the carp family (Cyprinidae) have evolved distinctive abilities to survive under cold stress, but molecular mechanisms underlying the generation of cold resistance remain largely unknown. In this study, we compared transcriptomic profiles of two carp species to identify key factors and pathways for cold tolerance and acclimation. Results: Larvae of Songpu mirror carp and Barbless carp that were pretreated at 18°C for 24 hours significantly improved their survival rates under lethal cold temperature at 8°C or 10°C, indicating that two carp species possess the ability of cold acclimation. However, Songpu mirror carp exhibited stronger abilities of cold tolerance and acclimation than Barbless carp. Transcriptomic profiles of Songpu mirror carp and Barbless carp larvae at 28°C and 18°C were compared during cold acclimation through RNA-seq. Differentially expressed genes that are closely associated with the differences in cold acclimation between two carp species were identified through bioinformatics and Venn's diagram analysis. GO enrichment analysis of these genes indicated that cellular component assembly involved in morphogenesis, secondary alcohol metabolism and drug transport were the most up-regulated biological processes during cold acclimation of Songpu mirror carp. Conversely, positive regulation of macroautophagy, intracellular protein transport, and organonitrogen compound catabolism were the most down-regulated biological processes during cold acclimation of Barbless carp. KEGG enrichment analysis revealed that factors in the FoxO-related signaling pathways are mainly responsible for the development of differences in cold tolerance and acclimation between two carp species since altering the phosphorylation of key proteins in the FoxO-related signaling pathways with inhibitors or an activator significantly decreased the cold tolerance and acclimation of Songpu mirror carp. These data provided key clues for dissection of molecular mechanisms underlying the development of cold tolerance and acclimation in carps. Conclusions: These findings indicate that larvae of two carp species possess different abilities of cold tolerance and can build cold acclimation under mild low temperature. Multiple biological processes and FoxO-related signaling pathways are closely associated with the development of differences in cold tolerance and acclimation between two carp species.

Abstract
Background: Diabetic limb ulcers are highly prevalent and contribute to a significant increase in cost for the treatment of these patients in health services. However, healing of these wounds is a major health problem and may even lead to amputation. The primary aim of the current study is to evaluate the efficacy of hyperbaric oxygen therapy (HBOT) in facilitating the healing of diabetic foot ulcers, in addition to secondarily evaluating whether it reduces the number of amputations and improves the quality of life in these patients. Methods: A non-blind randomised clinical study will be conducted in the city of Imperatriz, Maranhão state, Brazil from 2019 to 2020, in diabetic patients with chronic foot ulcers (classified as Wagner grade 2, 3, and 4, persisting for more than one month). The outpatient follow-up for diabetic foot patients will be done at the Unified Health System, with a sample size of 120 patients (the randomisation allocation will be 1:1, being 60 patients for each arm). Half of the patients will receive standard treatment, i.e. dressings, debridement, antibiotics, and load relief, along with HBOT (HBOT group), and the other half will receive only standard treatment (control group). The patients of the HBOT group will be evaluated upon admission, after 10, 20, 30 and 35 HBOT sessions, and after six months and one year. The patients of the control group will also be evaluated at equivalent periods (upon admission, after 2, 4, 6 and 7 weeks, six months and one year). The SF-36 quality of life questionnaire will be filled upon admission and after three months of follow-up in both groups. The primary and secondary endpoints will be assessed with 1 year of follow-up. Discussion: Diabetic foot ulcers are a highly prevalent complication of diabetes with serious consequences. A study to assess the efficacy of HBOT in healing the ulcers and reducing the rate of amputations in diabetic patients is justified, which will eventually aid in the development of guidelines for treating these ulcers.

Published: June 2020

Abstract
Background: Akebia trifoliata (Thunb.) Koidz, a perennial wild woody liana, can be used as biofuel to generate bioenergy, as well as a traditional Chinese medicine plant,and new potential edible fruit crop, due to its high yields in fields, wide adaptability, high economic, medicinal and nutritive values, and tolerance tocultivation conditions. However, the pericarp of A. trifoliata cracks longitudinallyalong the ventral suture during fruit ripening, which is a serious problem that limits its usefulness and causes significant losses in yield and commercial value. Furthermore, there have been no known investigations on fruit cracking and its molecular mechanisms in A. trifoliata . Results: In this study, the dynamic structural changes in fruit pericarps were observed, revealing that the cell wall of fruit pericarp became thinner, and had reduced integrity, and that the cell walls began to degrade in the cracking fruits compared to those observed in non-cracking fruits. Moreover, analyses of the complementary RNA- sequencing-based transcriptomes and tandem mass tag-based proteomes at different development stages during fruit ripening were performed, and the expression of various genes and proteins was found to be changed after cracking, The mRNA levels of 20 differentially expressed genes and 17 differentially abundant proteins (DAPs) involved in cell wall metabolism were further analyzed; 20 DAPs were also validated through parallel reaction monitoring analysis. Among these, pectate lyases and pectinesterase involved in pentose and glucuronate interconversions, β-galactosidases 2 involved in galactose metabolism, were significantly up-regulated in cracking fruits compared to levels in non-cracking fruits, suggesting that they might play crucial roles in A. trifoliata fruit cracking. Conclusions: This study provides new insights into the molecular basis of fruit cracking in A. trifoliata fruits and important clues for further studies on the genetic improvement of A. trifoliata and the breeding of non-cracking varieties.

Published: June 2020

Abstract
Background Marking mosquitoes is vital for mark-release-recapture and many laboratory studies, but their small size precludes the use of methods that are available for larger animals such as unique identifier tags and radio devices. Fluorescent dust is the most commonly used method to distinguish released individuals from the wild population. Numerous colours and combinations can be used, however, dust sometimes affects longevity and behaviour so alternatives that do not have these effects would contribute substantially. Rhodamine B has previously been demonstrated to be useful for marking adult Aedes aegypti males when added to the sugar meal. Unlike dust, this also marked the seminal fluid making it possible to detect matings by marked males in the spermatheca of females. Here, marking of Anopheles gambiae sensu stricto with rhodamine B and uranine was performed to estimate their potential contribution. Methods Two fluorescent markers, rhodamine B and uranine, were dissolved in sugar water and fed to adult An. gambiae. Concentrations that are useful for marking individuals and seminal fluid were determined. The effects on adult longevity, the durability of the marking and detection of the marker in mated females was determined. Male mating competitiveness was also evaluated.Results Rhodamine B marking in adults is detectable for at least three weeks, however uranine marking declines with time and at low doses can be confused with auto-fluorescence. Both can be used for marking seminal fluid which can be detected in females mated by marked males, but, again, at low concentrations uranine-marking is more easily confused with the natural fluorescence of seminal fluid. Neither dye affected mating competitiveness.Conclusions Both markers tested could be useful for field and laboratory studies. Their use has substantial potential to contribute to a greater understanding of the bio-ecology of this important malaria vector. Rhodamine B has the advantage that it appears to be permanent and is less easily confused with auto-fluorescence. The primary limitation of both methods is that sugar feeding is necessary for marking and adults must be held for at least 2 nights to ensure all individuals are marked whereas dusts provide immediate and thorough marking.

Abstract
Background: Remote ischemic conditioning during cerebral ischemia (remote ischemic perconditioning, RIPerC) refers to the application of several cycles of brief ischemia and reperfusion (I/R) commonly to a limb, and it represents a new paradigm in neuroprotection with multiple mechanisms of action in ischemic stroke (IS) patients during acute phase. Some clinical trials just finished, and a few others are still ongoing; gather the current knowledge and pull it down to influence the present and future studies was the goal of this paper. Methods: A systematic review of published research papers and/or registered clinical trials since 2000 was performed. Results: Nineteen studies were identified and only four studies were completed. All of them have demonstrated that RIPerC is safe, feasible and well tolerated in IS patients. However, a high heterogeneity of clinical trial characteristics was observed: five (26.3%) randomized clinical trials (RCTs) included only thrombolytic-treated patients, three (15.8%) RCTs only thrombectomy-treated patients, and five (26.3%) RCTs required radiological confirmation of IS. Temporal inclusion criteria vary from 4h to 48h. Most of the clinical trials used 4 cycles of RIPerC in the upper non-affected limb. Interestingly, only three (16.7%) RCTs applied RIPerC during the transportation in the ambulance. Neuroimaging outputs were the main endpoints when endovascular therapy was applied; functional outcome is also the main endpoint in large-medium size studies. Conclusions: This review summarizes the completed and ongoing clinical trials on RIPerC in IS patients, where RIPerC has been used alone or in combination with recanalization therapies. Ongoing clinical trials will provide new information on the best RIPerC intervention strategy and potentially improve the functional outcome of IS patients; definition of new RIPerC strategies would ideally aim at enhancing tissue preservation, promoting neurological recovery, and stratify patients to improve treatment feasibility.

Published: June 2020

Abstract
Background: The frequency of alpha thalassemia trait is about 40% in the Kuwaiti population, but there has been no comprehensive study of the prevalent alleles. This is a report of the patients who were referred for molecular diagnosis over a 20-year period.Methods: This is a retrospective study of the a-globin genotypes obtained in the Hemoglobin Research Laboratory of the Department of Pediatrics, Kuwait University from 1994 to 2015. Genotyping was by a combination of PCR, allele-specific oligonucleotide hybridization and reverse dot-blot hybridization (Vienna Lab Strip Assay).Results: Four hundred samples were characterized and analyzed from individuals aged <1 month to 80 years, with a median of 6 years from 283 unrelated families.. Most (90.8%) were Kuwaiti nationals. The common genotype was homozygosity for the polyadenylation-1 mutation (αPA-1α/α PA-1α) in 33.3%, followed by heterozygosity (αα/α PA-1α) for the same mutation in 32.3%. The PA-1 was therefore the most frequent allele (0.59). The frequency of the α0, –MED was 0.017. Rare alleles that were found in very low frequencies included the α0 (--FIL) in a Filipino child, Hb Constant Spring, Hb Adana, and Hb Icaria.Conclusion: There is a wide variety of alpha thalassemia alleles among Kuwaitis, but the nondeletional PA-1 is by far the most common cause of moderate to severe HbH (β4 tetramer), disease phenotype. The α0 (–MED) allele is also encountered, which has implications for pre-marital counselling especially the possibility of having babies with alpha thalassemia major (Barts hydrops fetalis).

Abstract
Background: Microbial cell factories are usually engineered and employed for cultivations that combine product synthesis with growth. Such a strategy inevitably invests part of the substrate pool towards the generation of biomass and cellular maintenance. Hence, engineering strains for the formation of a specific product under non-growth conditions would allow to reach higher product yields. In this respect, isoprenoid biosynthesis represents an extensively studied example of growth-coupled synthesis with rather unexplored potential for growth-independent production. Rhodobacter sphaeroides is a model bacterium for isoprenoid biosynthesis, either via the native 2-methyl-D-erythritol 4-phosphate (MEP) pathway or the heterologous mevalonate (MVA) pathway, and for poly-β-hydroxybutyrate (PHB) biosynthesis.Results: This study investigates the use of this bacterium for growth-independent production of isoprenoids, with amorpha-4,11-diene as reporter molecule. For this purpose, we employed the recently developed Cas9-based genome editing tool for R. sphaeroides to rapidly construct single and double deletion mutant strains of the MEP and PHB pathways, and we subsequently transformed the strains with the amorphadiene producing plasmid. Furthermore, we employed 13C-metabolic flux ratio analysis to monitor the changes in the isoprenoid metabolic fluxes under different cultivation conditions. We demonstrated that active flux via both isoprenoid pathways while inactivating PHB synthesis maximizes growth-coupled isoprenoid synthesis. On the other hand, the strain that showed the highest growth-independent isoprenoid yield and productivity, combined the plasmid-based heterologous expression of the orthogonal MVA pathway with the inactivation of the native MEP and PHB production pathways.Conclusions: Apart from proposing a microbial cell factory for growth-independent isoprenoid synthesis, this work provides novel insights about the interaction of MEP and MVA pathways under different growth-conditions.

Authors: Deng Qingwen , Liu Wenbin 
Published: June 2020

Abstract
Background: Limited diffusion and utilization of health technology have greatly halted the improvement of resource integration and healthcare outcomes. However, the dynamic mechanism of health technology diffusion in the context of the integrated care system (ICS) remained largely unknown. The purpose of this study is to develop and validate the scale on Dynamics of Health Technology Diffusion in Integrated Care System (DHTDICS) for providing instruments to investigate the health technology diffusion in the ICS. Methods: The scale with 39 items was initially designed on the basis of the proposed model developed from previous research. And it was validated in a cross-sectional questionnaire survey including 246 participants. Exploratory factor analysis was used to assess domains in the questionnaire, and analyzed correlation, factorials, internal consistency and validity of the questionnaire. In addition, structural equation modeling was performed to determine the total effects of each domain on the health technology diffusion in the ICS.Results: Reliability analysis revealed excellent internal consistency, as the value of Cronbach’s alpha greater than 0.80 for all of the four DHTDICS domains in this study. An acceptable validity was confirmed through tests of construct validity, convergent validity and discriminant validity. With respect to the potential domains and dimensions that DHTDICS contributes, the results highlight the existence of 4 domains: personal beliefs, technical drivers, organizational readiness, and external environment. Among them, the impact on health technology diffusion is, in descending order, organizational readiness, personal beliefs, external environment, and technical drivers.Conclusions: The findings of this study support the validity of the DHTDICS, and will be a helpful reference for developing future intervention strategies to promote health technology diffusion in the ICS.
