Abstract
The exact pathogenesis of polycystic ovary syndrome (PCOS), the most common neuroendocrine disorder in women of reproductive age, has not been fully elucidated. Recent studies suggested that chronic inflammation and neurotransmitter disorder involved in the progress of PCOS. Troxerutin, a natural flavonoid, was reported to possess neuroprotective effect in several disease models by inhibiting inflammation or enhancing neurotrophic factor. In this study, we investigated the possible protective effect and mechanism of troxerutin in a dihydrotestosterone (DHT)-induced rat model of PCOS. The PCOS rat models were treated with troxerutin at a dose of 150mg/kg or 300mg/kg for up to 4 weeks. Results showed that 300mg/kg troxerutin significantly decreased the body weight gain and improved the pathological changes of ovary induced by DHT. Meanwhile, the elevated gonadotrophin-releasing hormone (GnRH), gonadotrophin and testosterone in the serum of PCOS rats were reduced with the treatment of troxerutin. The expression of kisspeptin and NKB in arcuate nucleus and their receptors kiss1r and NK3r in GnRH positive neurons of median eminence were markedly decreased in troxerutin-treated rats. Of note, the GnRH inhibitory regulator GABA and stimulatory regulator glutamate were also restored to the normal level by troxerutin. The present study indicated that troxerutin may exhibit a protective effect in PCOS rat model via regulating neurotransmitter release.

Abstract
Background

Community dialogues have been used in various participatory approaches in various health prevention and awareness programs, including family planning interventions to increase understanding and alignment of particular issues from different peoples’ perspectives. The feasibility testing comprised of the implementation of a community dialogue intervention which generated discussion on key issues that needed to be addressed to decrease the unmet need for family planning- in this instance improving Quality of Care; and an evaluation thereof. The aim of this paper is to document the evaluation of the feasibility testing of a community dialogue approach, as part of formative phase research, in order to increase community and health care provider dialogue about family planning and contraceptives.

Methods

The operational and cultural feasibility of the community dialogue was evaluated through participant observations during the dialogue, using a standardised feasibility testing tick-list, and through focus group discussions with three different groups of stakeholders who participated in the community dialogue.

Results

Overall, 21 of the 30 invited participants attended the meeting. The approach created dialogue on family planning and QoC as per the objectives of the feasibility testing. There was a dialogue about how the quality of care could be achieved in family planning from the divergent stakeholders, guided by the agreed-upon ground rules. A need for more time for discussion and representation from the adolescents and other stakeholders in family planning such as the nutritionist was noted. Some participants were not comfortable with the language used, while others felt the other participants had more knowledge about the topics discussed.

Conclusion

Generally, the community dialogue was well received by the community members and the healthcare providers, as was seen from the positives sentiment expressed by both categories. Some key considerations for refining the approach included soliciting maximum participation from otherwise marginalized groups like the youths would provide stronger representation.

Abstract
Background Results on the association between trans-β-carotene and obesity are less clear and little is known about how their relationship may be affected by plasma glucose levels.The present study aimed to evaluate the relationships between trans-β-carotene and obesity and to investigate whether plasma glucose levels had a modifying effect on these relationships. Methods Children aged 6-18 years were selected from the National Health and Nutrition Examination Survey(NHANES) (2001–2006) (n =8030). The serum trans-β-carotene levels were divided into tertiles, and their associations with obesity were evaluated using multivariable-adjusted linear regression models adjusted for potential confounding factors. The interaction effects between trans-β-carotene levels and plasma glucose levels on obesity were further evaluated. Results In the fully adjusted model, using serum trans-β-carotene as natural log-transformed continuous variable, the negative association between trans-β-carotene level and obesity were confirmed. In addition, plasma glucose levels significantly modified the inverse association between trans-β-carotene and obesity (p value for interaction: 0.09). A stronger association of trans-β-carotene levels with obesity was found in higher plasma glucose levels (more than100 mg/dl) than in lower plasma glucose levels. Further, a non-linear relationship was detected between trans-β-carotene and obesity in participants with higher plasma glucose levels, with an inflection point of 2.7 (trans-β-carotene =14.88 ug/dl). The effect sizes and confidence intervals for the left and right sides of the inflection point were 0.10 (0.00 to 0.2) and 6.7 (0.1 to 348.2), respectively. Conclusion Our findings indicate that the association between trans-β-carotene concentration and obesity is stronger in individuals with higher plasma glucose population than in those with lower plasma glucose levels.

Abstract
Objective : Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessively inherited disorder characterized by insensitivity to noxious stimuli and inability to sweat. Methods : In this case report, an 18-year-old Chinese boy diagnosed with CIPA with the clinical features of loss of algesthesis, inability to sweat, self-mutilation, developmental delay and dislocation of the left hip joint. Blood samples from the patient was collected and subjected to genetic analysis. Results : Sequencing analysis revealed a novel mutation, c.1769A>G, in the neurotrophic tyrosine kinase receptor type 1 gene (NTRK1). In silico studies suggested that the mutations described are detrimental to the function of the protein encoded by the NTRK1 gene. Conclusions : The novel mutation widen the genetic mutation spectrum of NTRK1 in CIPA patients, and provide more evidence for precise diagnosis of the clinically suspected patients with CIPA.

Published: March 2020

Abstract
Background: Androgen insensitivity syndrome (AIS) is a rare disease caused by mutations in the AR gene. This results in resistance to the actions of androgen as well as a female phenotype with 46 XY. Anatomically, individuals with AIS lack both a uterus and ovaries. Case presentation: In this case report, we detail a 32-year-old patient with complete AIS (CAIS). This female patient with 46 XY genotype came to our hospital seeking surgical removal of bilateral testis. The subsequent medical history, clinical examination, imaging, and endocrine outcomes from this patient were collected and are presented here. Conclusions: Individuals with CAIS need appropriate care from doctors and support from their family. The diagnosis, treatment, and management of CAIS also requires a multidisciplinary approach.

Abstract
Image processing is a field in which biometric traits such as Face, voice, lip movements, hand geometry, odour, gait, iris, retina, fingerprint etc., are essential for recognition. The face is the most critical biometric trait for recognition because the face is an easily approachable biometric trait. There is no need for attention from a human being for face recognition. Human face classification is a challenging task for a machine. In this project, minimum distance classifier used with LASSO based gender classification. Database of 100 images (50 male and 50 female face images which considered from 4 different databases) used for face recognition and classification. Original face image database used for the gender classification. This approach of dual classfication ((1) Recognizing or classfying human faces from various objects and (2) Classifying gender through face recognition) is made possible with the help of combining modified SIFT feature in combination with ridge regression (RR), elastic net (EN) and lasso regression with GSVM (LRGS) based classificatioins. The final classfication results with accuracy are as follows for RR- 89.6%, EN- 93.5%, LR-93.2% and propsed approach(LRGS) with 98.4% accurate detection rate with rediction names.

Abstract
BackgroundAs parasites spend a large amount of their life cycles on their hosts, to gain a better understanding of how host-parasite systems work, information about the life cycle of the parasite is important. Numerous laboratory and few field-based studies have explored the influence of microclimates on developmental times of different stages of various species of ixodid ticks and found that most of these species develop quicker and survive better at temperatures between 18 and 26°C and relative humidity between 75% and 94%. Ixodes anatis Chilton, 1904, or kiwi tick, is an endophilic, nidicolous species endemic to North Island brown kiwi (Apteryx mantelli, NIBK) and the Tokoeka (Apteryx australis). Little is known about the environmental conditions that are ideal for the development of the kiwi tick. Our aims in this study were to determine and compare the conditions of temperature and RH that ensured the best survival, and the shortest interstadial periods for the kiwi tick, in the laboratory and outdoors inside artificial kiwi burrows.MethodsWe collected free walking engorged ticks off wild kiwi hosts and placed them in the laboratory at various fixed temperature and humidity regimes. We also placed sets of different stages of these ticks in artificial kiwi burrows and in both cases, recorded the times taken for the ticks to moult to the next stage.ResultsWe found that temperature had a larger impact on the moults between stages than relative humidity, and larvae and nymphs both showed optimum development between 10-20°C, which is lower than many other species of Ixodid ticks. However, larvae moulted quicker and survived better when saturation deficits were <1-2 mmHg (RH>94%) while for nymphs the optimum saturation deficits were 1-10 mmHg.ConclusionsWe believe that the kiwi tick has adapted to stable, but relatively cool and humid conditions in the burrows reflecting the evolutionary consequences of its association with the kiwi.

Abstract
Background: Giant cell tumor of soft tissues (GCT-ST) is a low malignant uncommon neoplasm, with is histological and immunophenotype similar to that of GCT of bone. Primary giant cell tumor of soft tissue arising in the thyroid is exceedingly rare. Case presentation: We reported a new case of GCT-ST originating from the thyroid occurring in 69-year-old woman. Histologically, the tumor was composed of two morphological components, mononuclear cells admixed with multinucleated osteoclast-like giant cells. Tumor is devoid of atypia, pleomorphism, and atypical mitosis. Immunohistochemically, the tumor cells showed strongly positivity with antibodies to CD68, but were negative for AE1/AE3, EMA and additional muscle markers. Conclusions: Due to its rare occurrence, we analyzed the clinical features of patients with primary thyroid GCT-ST to summarize some of our experiences and conduct a literature. The interest of this case lies in the rarity of this entity, the difficulty in preoperative diagnosis, and the confusion with other malignancies.

Abstract
Background Periodontal ligament stem cells (PDLSCs) have many applications in the field of cytotherapy, tissue engineering, and regenerative medicine. However, the effect of age on the biological characteristics and immunoregulation of PDLSCs remains unclear. Methods In this study, we compared PDLSCs isolated from young and elderly individuals. PDLSCs proliferation was analyzed by Cell Counting Kit-8 (CCK-8) and 5-ethynyl-2'-deoxyuridine (EdU) staining, and apoptosis level was detected by Annexin V-PE/7-ADD staining. PDLSCs osteogenic/adipogenic differentiation potentials were assessed by alkaline phosphatase (ALP), Alizarin Red, Oil Red O staining and related quantitative analysis. PDLSCs immunoregulatory capacity was determined by EdU and Annexin V-PE/7-ADD staining. To explore its underlying mechanism, microarray, quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR), and western blot analyses were performed to detect differentially expressed genes and proteins in PDLSCs. Results Our results demonstrated that with aging, the proliferation and osteogenic/adipogenic differentiation potential of PDLSCs decreased, whereas apoptosis of PDLSCs increased. Moreover, the immunosuppressive ability of PDLSCs decreased with aging. Compared with PDLSCs from young subjects, analysis of mRNA expression revealed an upregulation of CCND3 and RC3H2 , and a downregulation of Runx2, ALP, COL1A1, PPARγ2, CXCL12, FKBP1A, FKBP1B, NCSTN, P2RX7, PPP3CB, RIPK2, SLC11A1, and TP53 in those from elderly individuals. Furthermore, protein expression levels of Runx2, ALP, COL1A1, and PPARγ2 in the elderly group was decreased, whereas that of CCND3 increased. Conclusions Taken together, aging influences biological and immunological characteristics of PDLSCs, and thus it is more appropriate to utilized PDLSCs from young individuals for tissue regeneration, post-aging treatment, and allotransplantation.
Priority domains, aims, and testable hypotheses for implementation research: A scoping review and evidence map protocol
Authors: Garner Bryan R , Patel Sheila , Kirk M. Alexis 
Published: March 2020

Abstract
Background: The challenge of implementing evidence-based innovations within practice settings is a significant public health issue the field of implementation research (IR) is focused on addressing. Significant amounts of funding, time, and effort have been invested in IR to date, yet there remains significant room for advancement, especially regarding IR’s development of scientific theories as defined by the National Academy of Sciences (i.e., a comprehensive explanation of the relationship between variables that is supported by a vast body of evidence). Research priority setting (i.e., promoting consensus about areas where research effort will have wide benefits to society) is a key approach to helping accelerate research advancements. Thus, building upon existing IR, general principles of data reduction, and a general framework for moderated mediation, this article identifies priority domains, aims, and testable hypotheses for IR and describes a scoping review protocol to identify and map the extent to which IR has examined these priorities to date.Methods: Implementation Science is the leading journal for publishing IR and receives over 800 submissions annually. Thus, this scoping review will focus on IR published in Implementation Science between its inception in 2006 and 12/31/2019. The current scoping review and evidence map protocol has been developed in accordance with the approach developed by Arksey & O’Malley and advanced by Levac, Colquhoun, and O’Brien. All research articles and short reports will be reviewed. Because scoping reviews seek to provide an overview of the identified evidence base rather than synthesize findings from across studies, we plan to use our data-charting form to provide a descriptive overview of implementation research to-date and summarize the research via one or more summary tables. We will use the priority aims and testable hypotheses (PATH) diagram, which integrates the four priority domains, three priority aims, and four priority testable hypotheses, to develop a map of the evidence (or lack thereof).Discussion: This scoping review and evidence map is intended to help accelerate IR focused on one or more of IR’s priority aims and testable hypotheses, which in turn will accelerate IR’s development of NAS-defined scientific theories and, subsequently, improvements in public health.Systematic review registration: Open Science Framework: https://osf.io/3vhuj/

Abstract
Backgrounds: The outbreak of COVID-19 caused by a novel coronavirus, SARS-CoV-2, has been listed as a public health emergency of international concern by WHO. Most COVID-19 patients presented with a mild infection, but many challenges exist in therapy of severe and critical severe patients. This paper systematically reviewed clinical features, treatments and outcomes of severe and critical severe patients infected COVID-19. Methods: The clinical, laboratory, imaging features, treatment and outcomes of COVID-19 were collected. The data were analyzed by using STATA 15 statistical software to estimate the prevalence and 95% CI in severe and critical severe patients with COVID-19. A random or fixed effect model was used to estimate the prevalence and 95% CI. Results: After screening, 8 studies including a total of 275 patients were included in this meta-analysis. The percentage of severe and critical severe patients in confirmed COVID-19 cases was 25% (95% CI 16-36%). Fever, cough, dyspnea, lymphopenia and bilateral distribution of patchy shadows were the most prevalent findings in these patients. Utilization rate of antiviral drugs, corticosteroid, non-invasive ventilation, invasive mechanical ventilation was high in therapy strategies. The most prevalent complications were ARDS, shock, and acute cardiac injury. Discussion: Severe and critical severe COVID-19 patients usually had complications even a fatal outcome. As vaccines and anti-coronaviral drugs are under development, the principles of treatment for these patients should be focused on improving oxygenation, lung protective and function support of multiple organs.

Abstract
Background Human T-cell lymphotropic virus (HTLV) remains a concern for blood safety. The detection of HTLV has not yet been applied for routine blood screening in China, even though lots of HTLV positive cases have been reported in southeastern China. However, data on the prevalence of HTLV infection among blood donors is limited. Objective The objective was to investigate the prevalence of HTLV among blood donors in three representative blood centers in China and evaluate the feasibility of chemiluminescence immunoassay (CLIA) for blood screening. Methods From November 2018 to March 2019, blood plasma samples collected from Hebei, Changsha and Shenzhen blood centers were screening for HTLV-1/2 antibody using Lumipulse G HTLV-I/II Immunoreaction Cartridges set (CLIA) and enzyme-linked immunosorbent assay (ELISA), followed with confirmatory test using INNO-LIA HTLV I/II. Results A total of 59929 blood donations were collected and screened for HTLV-1/2. The reactive rate of CLIA and ELISA among donations in Shenzhen blood center (0.0943%, 27/28621) was higher than Hebei (0.0248%, 4/16144) and Changsha (0.0198%, 3/15164) ( P <0.05). After confirmation, 3 samples were confirmed as indeterminate for HTLV antibodies, only 1 sample from Shenzhen blood center was confirmed and typed as HTLV-1. The overall prevalence of HTLV-1/2 was 1.67 per 100,000 (1/59929). The HTLV-infected blood donor was a first female donor at age 32 with high school degree, born in Fujian province, and SHE minority. Conclusion In summary, the overall prevalence of HTLV-1/2 among blood donors in the tree blood centers in China remains relatively low. However, blood donations with positive or indeterminate results for HTLV antibodies found in the study reminded us the importance of HTLV screening among blood donors in China. In the view of HTLV prevalence and cost, all the first-blood donors should undergo HTLV screening as a systematic strategy to reduce the risk of transmission of HTLV through blood transfusion.

Abstract
BACKGROUND This report describes a process for designing a 3D printed patient-specific applicator for HDR brachytherapy of the orbit. CASE PRESENTATION A 34-year-old man with recurrent melanoma of the orbit was referred for consideration of re-irradiation. An applicator for HDR brachytherapy was designed based on the computed tomography (CT) of patient anatomy. The body contour was used to generate an applicator with a flush fit against the patient’s skin while the planning target volume (PTV) was used to devise channels that allow for access and coverage of the tumor bed. An end-to-end quality assurance test was devised to determine feasibility for clinical use. The applicator was designed to conform to the volume and contours inside the orbital cavity. Support wings placed flush with the patient skin provided stability and reproducibility, while 16 source channels of varying length were needed for sufficient access to the target. A solid sheath, printed as an outer support-wall for each channel, prevented bending or accidental puncturing of the surface of the applicator. CONCLUSIONS Quality assurance tests demonstrated feasibility for clinical use. Our experience with available 3D printing technology used to generate an applicator for the orbit may provide guidance for how materials of suitable biomechanical and radiation properties can be used in brachytherapy.
