Abstract
Background: Overweight and obesity are becoming a big issue in Shandong province. Based on the big data of children and adolescents in Shandong province, we try to explore the spatial differences and explain the causes of this phenomenon, so as to provide suggestions and data support for solving related problems in similar areas. Methods: The sample came from Shandong province's physical examination data in 2017. A total of 10.27 million schoolchildren aged 6-18 years were included. ArcGIS software (hot spot analysis) was used to explore the spatial differences, and regional influencing factors were analyzed by multinomial logistic regression.Results: The prevalence of overweight and obesity among schoolchildren aged 6-18 years were 17.93% and 6.79%, respectively. Moreover, boys/girls, urban/rural areas both showed that the former rate was higher than the latter, and the 9-11 age group was confirmed to have the highest prevalence. Regional distribution illustrated that, in Shandong province, the areas with high prevalence of overweight and obesity were mainly concentrated in the central, northern and eastern parts, and the hot spot clusters were located in Yantai and Weihai, while the low-value areas were aggregated in the western (boys) and southern (girls) regions. Further exploration revealed that total retail sales of consumer goods (CGTRS) and per capita disposable income (PCDI) were confirmed as risk factors for regional obesity level.Conclusions: The spatial difference of overweight and obesity is statistically significant between the eastern region (high value cluster) and the western region (low value cluster), and it is influenced by some regional factors, suggesting that for a few regions, relevant department should pay more attention to this phenomenon. More education on this problem should be done to make people know more about health, and more researches should be done to see what intervention could solve this problem.

Abstract
Background: The Service Availability and Readiness Assessment (SARA) surveys generate data on the readiness of health facility services. We constructed a readiness index related to malaria services and determined the association between health facility malaria readiness and malaria mortality in children under the age of 5 years in Burkina Faso.Methods: Data on inpatients visits and malaria-related deaths in under 5-year-old children were extracted from the national Health Management Information System (HMIS) in Burkina Faso. Bayesian geostatistical models with variable selection were fitted to malaria mortality data. The most important facility readiness indicators related to general and malaria-specific services were determined. Multiple correspondence analysis (MCA) was used to construct a composite facility readiness score based on multiple factorial axes. The analysis was carried out separately for 112 medical centres and 546 peripheral health centres.Results: Malaria mortality rate in medical centres was 4.8 times higher than that of peripheral health centres (3.46% vs. 0.72%, p<0.0001). Essential medicines was the domain with the lowest readiness (only 0.1% of medical centres and 0% of peripheral health centres had the whole set of tracer items of essential medicines). Basic equipment readiness was the highest. The composite readiness score explained 30% and 53% of the original set of items for medical centres and peripheral health centres, respectively. Mortality rate ratio (MRR) was by 59% (MRR = 0.41, 95% Bayesian credible interval (BCI): 0.19-0.91) lower in the high readiness group of peripheral health centres, compared to the low readiness group. Medical centres readiness was not related to malaria mortality. The geographical distribution of malaria mortality rate indicate that regions with health facilities with high readiness show lower mortality rates.Conclusion: Performant health services in Burkina Faso are associated with lower malaria mortality rates. Health system readiness should be strengthened in the regions of Sahel, Sud-Ouest and Boucle du Mouhoun. Emphasis should be given to improving the management of essential medicines and to reducing delays of emergency transportation between the different levels of the health system.

Abstract
Background: A number of studies have shown that genetic factor plays an important role in etiology of panic disorder (PD). The aim of the present study was to examine the association of serotonin-related gene polymorphisms with PD risk. Then, we analyzed the correlation between these gene polymorphisms and response to sertraline drug. Methods: 233 patients with PD and 231 healthy controls were enrolled in the study. Panic Disorder Severity Scale (PDSS) were administered to all subjects, and all patients in the study were also assessed after 4 weeks of treatment. The SLC6A4(rs140701, rs3813034, 5-HTTLPR and STin2), 5-HTR1A rs6295, 5-HTR2A rs6313 and COMT rs4680 gene polymorphisms were genotyped and assessed for the potential association. Results: The allelic model showed that the SLC6A4 rs140701 polymorphism variant was significantly associated with increased risk of PD (OR = 0.624, 95 % CI 0.450-0.864, p <0.05), and a significant result was found in the dominant model (OR = 0.546; 95% CI, 0.371-0.804, p <0.05). There was a significant difference in allele and genotype frequency between responders and nonresponders in the 5-HTTLPR polymorphism (OR = 0.205, 95 % CI 0.128-0.328; OR = 0.249, 95 % CI 0.155-0.401, both p <0.001), indicating the PD patients with S-allele had a poorer response to sertraline than L-allele carriers. Conclusion s : The present study suggests that the SLC6A4 rs140701 polymorphism variant may be associated with susceptibility to PD, and 5-HTTLPR polymorphism may be a predictor of response to sertraline in the treatment of PD.

Abstract
Background: To investigate predictors of pathological invasiveness and prognosis of lung adenocarcinoma in patients with pure ground-glass nodules (pGGNs). Methods: Clinical and computed tomography (CT) features of invasive adenocarcinomas (IACs) and pre-IACs were retrospectively compared in 641 consecutive patients with pGGNs and confirmed lung adenocarcinomas who had undergone postoperative CT follow-up. Potential predictors of prognosis were investigated in these patients. Results: Of 659 pGGNs in 641 patients, 258 (39.1%) were adenocarcinomas in situ, 265 (40.2%) were minimally invasive adenocarcinomas, and 136 (20.6%) were IACs. Respective optimal cutoffs for age, serum carcinoembryonic antigen concentration, maximal diameter, mean diameter, and CT density for distinguishing pre‑IACs from IACs were 53 years, 2.19 ng/mL, 10.78 mm, 10.09 mm, and −582.28 Hounsfield units (HU). Univariable analysis indicated that sex, age, maximal diameter, mean diameter, CT density, and spiculation were significant predictors of lung IAC. In multivariable analysis age, maximal diameter, and CT density were significant predictors of lung IAC. During a median follow-up of 41 months no pGGN IACs recurred. Conclusions: pGGNs may be lung IACs, especially in patients aged > 55 years with lesions that are > 1 cm in diameter and exhibit CT density > −600 HU. pGGN IACs of < 3 cm in diameter have good post-resection prognoses.

Abstract
Background: Lumbar lordosis (LL) can be restored, and screw-related complications may be avoided with the stand-alone expandable cage method. However, the long-term spinopelvic changes and safety remain unknown. We aimed to elucidate the long-term radiologic outcomes and safety of this technique. Methods: Data from patients who underwent multi-level stand-alone expandable cage fusion and 80 patients who underwent screw-assisted fusion between February 2007 and December 2012, with at least 5 years of follow-up, were retrospectively analyzed. Segmental angle and translation, short and whole LL, pelvic incidence, pelvic tilt, sacral slope (SS), sagittal vertical axis, thoracic kyphosis, and presence of subsidence, pseudoarthrosis, retropulsion, cage breakage, proximal junctional kyphosis (PJK), and screw malposition were assessed. The relationship between local, lumbar, and spinopelvic effects was investigated. The implant failure rate was considered a measure of procedure effectiveness and safety. Results: In total, 69 cases were included in the stand-alone expandable cage group and 150 cases in the control group. The stand-alone group showed shorter operative time (58.48±11.10 versus 81.43±13.75, P=.00028), lower rate of PJK (10.1% versus 22.5%, P=.03), and restoration of local angle (4.66±3.76 versus 2.03±1.16, P=.000079) than the control group. However, sagittal balance (0.01±2.57 versus 0.50 ±2.10, P=.07) was not restored, and weakness showed higher rate of subsidence (16.31% versus 4.85 %, P=.0018), pseudoarthrosis (9.92% versus 2.42%, P=.02), cage, and retropulsion (3.55% versus 0, P=.01) than the control group.Conclusions: Stand-alone expandable cage fusion can restore local lordosis; however, global sagittal balance was not restored. Furthermore, implant safety has not yet been proven.
Financial reimbursement - Irrelevant for GPs' readiness to implement brief intervention to reduce alcohol consumption? A cross-sectional vignette study.

Abstract
BACKGROUND: General Practitioners' (GPs) readiness to implement screening and brief intervention (SBI) to treat patients with excessive alcohol consumption is low. Several studies identified crucial barriers such as insufficient financial reimbursement. In contrast to the barriers-account, we assume that low implementation readiness of GPs may be less attributed to external barriers but rather more so to inherent characteristics of SBI. To test our assumption, we conducted a vignette study assessing the GPs' readiness to implement SBI in comparison to a pharmacological intervention also designed for the treatment of excessive drinkers in relation to standard or above-standard financial reimbursement. According to our hypothesis GPs should be less ready to implement SBI regardless of financial reimbursement. METHODS: A convenience sample of GPs was recruited to answer the questionnaire. To assess the GPs' implementation readiness a 4-item 6-point Likert scale was developed and pretested. RESULTS: One hundred forty GPs completed the questionnaire. GPs were more ready to implement the pharmacological intervention than SBI, F (1,132)=27.58, p >.001 (main effect). We found no effect for financial reimbursement, F (1,132)=3.60, ns , and no interaction effect, F (1,132)=2.20, ns . CONCLUSIONS: Further research should investigate more thoroughly the crucial characteristics of SBI to initiate a modification process finally leading to more effective primary care dependency prevention.

Published: July 2020

Abstract
Background: Transfer RNA-derived small RNAs (tsRNAs) are a recently discovered form of non-coding RNA capable of regulating myriad physiological processes. The role of tsRNAs in hMSC adipogenic differentiation, however, remains incompletely understood. The purpose of this study was to identify the novel tsRNA-16902 as a regulator of hMSC adipogenic differentiation.Methods: In this study we conducted transcriptomic sequencing of hMSCs after inducing their adipogenic differentiation, and we were thereby able to clarify the molecular mechanism underlying the role of tsRNA-16902 in this context via a series of molecular biology methods. Results: When we knocked down tsRNA-16902 expression, this impaired hMSC adipogenic differentiation and associated marker gene expression. Bioinformatics analyses further revealed tsRNA-16902 to target retinoic acid receptor γ (RARγ). Luciferase reporter assays also confirmed the ability of tsRNA-16902 to bind to the RARγ 3’-untranslated region. Consistent with this, RARγ overexpression led to impaired hMSC adipogenesis. Further analyses additionally revealed that Smad2/3 phosphorylation as increased in cells that either overexpressed RARγ or in which tsRNA-16902 had been knocked down. We also assessed the adipogenic differentiation of hMSCs in which tsRNA-16902 was knocked down and at the same time a Smad2/3 inhibitor was added to disrupt Smad2/3 phosphorylation. The adipogenic differentiation of hMSCs in which tsRNA-16902 was knocked down was further enhanced upon the addition of a Smad2/3 signaling inhibitor relative to tsRNA-16902 knockdown alone.Conclusions: Through a comprehensive profiling analysis of tsRNAs that were differentially expressed in the context of hMSC adipogenic differentiation, we were able to identify tsRNA-16902 as a previously uncharacterized regulator of adipogenesis. tsRNA-16902 is able to regulate hMSC adipogenic differentiation by targeting RARγ via the Smad2/3 signaling pathway. Together our results may thus highlight novel strategies of value for treating obesity.

Abstract
Background Visceral leishmaniasis (VL) was one of the most important parasitic diseases in China, caused by Leishmania protozoans and transmitted by sand flies. Recently VL cases have reappeared in China, including the extension region of the Loess Plateau . The purpose of this study was trying to reveal the reason of reappearance to the developing the prevention and control measures. Methods Sand flies were collected by light traps from rural areas in Shanxian, Henan, China in 2015, as well as in Wuxiang and Yangquan, Shanxi, China in 2017. The blood sources of sand flies were analyzed by PCR detecting the host-specific mitochondrial cytochrome b (mtDNA Cyt b ) gene fragments. Leishmania infection in sand flies was detected by amplifying and sequencing ribosomal DNA internal transcribed spacer 1 ( ITS1 ). The Leishmania specific antibodies in the sera of local dogs were detected by ELISA kit. Results Blood sources showed diversity in the extension region of the Loess Plateau, including human, chicken, dog, cattle, pig and goat. Multiple blood sources within a sand fly were observed in samples from Yangquan (17/118, 14.4%) and Wuxiang (12/108, 11.1%). Leishmania DNA was detected in sand flies collected from Yangquan with minimum infection rate of 1.00%. The ITS1 sequences were conserved with the Leishmania donovani complex. The positive rate of Leishmania specific antibodies in dogs was 5.97%. Conclusion This study detected the blood sources and Leishmania parasites infection of sand flies by molecular methods in the extension region of Loess Plateau, China. A high epidemic risk of leishmaniasis is currently indicated by the results as the infection of Leishmania in sand flies, the extensive blood sources of sand flies including humans, and positive antibody of Leishmania in local dog sera. Given the recent increase of VL cases, asymptomatic patients, dogs and other potential infected animals should be screened and treated. Furthermore, the density of sand flies needs to be controlled and personal protection should be strengthened.

Authors: Teodoro Renata Pereira , Scherrer Danielle , Camargo Maria José de , Costa Ana , Andrade Cecília Vianna de , RUSSOMANO FABIO BASTOS 
Published: July 2020

Abstract
Background

According to the Brazilian Guidelines on Cervical Cancer Screening, women with cytopathologic diagnosis of high-grade intraepithelial lesion, abnormal colposcopic findings, fully visible squamocolumnar junction, and age 25 years or older should be treated at the first visit (“see and treat – S&T”). The main limitation to this approach is the risk of overtreatment, identified by histology without preinvasive lesion. This study aimed to measure the negative histology rate in women submitted to S&T according to the Brazilian Guidelines.
Methods

This was a cross-sectional study that analyzed records from a database with 616 women submitted to S&T from 1996 to 2017. Negative histology was defined as the following histopathologic results: HPV without CIN, inflammatory, low-grade squamous intraepithelial lesion (LSIL), and CIN 1.
Results

Of the 616 women, there were 52 (8.44% − 95%CI 6.25–10.64%) with a histopathologic report without preinvasive cervical lesion. No statistical association was found between this outcome and younger ages or a significant downward trend over time.
Conclusion

The overtreatment rate in this study can be considered low and consistent with the acceptable rates reported in the literature, reinforcing the prevailing Brazilian guideline, in which the benefits of immediate treatment outweigh the risk of losses following biopsy.
Intervertebral disc vacuum phenomenon is associated with Modic changes in the adjacent endplate: implications for discogenic back pain
Authors: Liu Junhui , Xiang Yufeng , Shan Zhi , Fan Shunwu , Zhao Fengdong 
Published: July 2020

Abstract
Background: Back pain often arises from degenerative changes in lumbar intervertebral discs and their adjacent endplates. A painful endplate is not easy to identify in patients, but it could be possibly revealed by inflammatory-like ‘Modic’ changes and by a ‘vacuum phenomenon’ within the disc. We hypothesize that Modic changes and a VP often co-exist in those lumbar levels most closely associated with back pain. Methods: We scanned 1023 consecutive inpatients of the Department of Orthopaedics from 2015 August to 2018 August, all patients suffered from lumbar degenerative diseases. Whether the patients had back pain or not were evaluated, and the prevalence and location of vacuum phenomenon(VP) and Modic changes were compared at each spinal level. Results: 5115 discs were studied from 1023 patients. The number of discs showed to have a VP was 430 using CT. Of the 430 discs with a CT-diagnosed VP, 116 were L4-5, and 171 were L5-S1. 522 of the 5115 discs exhibited Modic changes, with the prevalence of type I, type II and type III Modic changes being 1.6%, 8.2% and 0.4% respectively. Modic changes usually occurred adjacent to L4-5 discs or L5-S1 discs. The prevalence of back pain was higher in the VP group than no-VP group, VP were significantly associated with Modic changes Type II at L4/5 and at L5/S1.Conclusion: VP are closely associated with back pain and Modic changes in the lower lumbar spine. Further investigations may be warranted when radiographs or CT identify a VP in a lumbar disc.

Published: July 2020

Abstract
Background: investigate the prevalence and The related factors between the two types of premature ejaculation (lifelong PE[LPE], acquired PE [APE] in men and atherosclerosis. Methods: One hundred patients complaining of PE and 100 control subjects were enrolled in this prospective study.All cases underwent a full medical history and Clinical examination.Blood pressure,serum lipid profile, testosterone,and Body mass index (BMI) were measured.The Arabic index of premature ejaculation (AIPE) and self-estimated (IELT) Intravaginal latency time was used for PE evaluation. Atherosclerosis was diagnosed by measuring the Carotid artery intima-media thickness (CIMT). Patients were divided into two major groups, (Group 1) [PE group] and (Group 2) [Control group]. Results: The mean age of cases in (group1) and (group 2) were 44.5 ± 11.7 versus 42.3 ± 10.8 yrs. The Systolic BP, diastolic (BP), Serum Triglycerides, serum LDL (BMI), the prevalence of atherosclerosis and smoking rate showed higher results in (group1) compared to group2, with significant difference (p<0.001). The IELT was significantly lower in group1 (2.67± 1.25) compared to group2 (3.77±1.52), (p<0.001). The prevalence of APE (74%) was significantly higher than LPE (26%) in group1(p<0.001). regression analysis revealed that patients with APE showed more comorbidities than LPE patients concerning the prevalence of atherosclerosis, hypertension, and hyperlipidemia (p<0.001 for all items).Both of APE and LPE were significantly related to age>35y, BMI ≥ 25 kg/m2, smoking, Bl pressure and hyperlipidemia (p<0.001 for all factors).Conclusions: Both types of PE,predominately the APE type,are associated with atherosclerosis, hypertension, and hyperlipidemia. The APE type reported more prevalence than the LPE.
