Abstract
Background Vector control through long lasting insecticidal nets and focal indoor residual spraying (IRS) is a major component of the Tanzania national malaria control strategy. In mainland Tanzania, IRS has been conducted annually around Lake Victoria basin since 2007. Due to pyrethroid resistance in malaria vectors, use of pyrethroids for IRS was phased out and from 2014 to 2017 pirimiphos-methyl (Actellic 300CS) was sprayed in regions of Kagera, Geita, Mwanza and Mara. Methods WHO Cone bioassays were conducted monthly on interior house walls to determine residual efficacy of pirimiphos-methyl CS. Indoor CDC light traps with or without bottle rotator were hung next to protected sleepers indoors and also set outdoors (un-baited) as a proxy measure for indoor and outdoor biting rate and time of biting. A sub-sample of Anopheles were tested by PCR to determine species identity and ELISA for sporozoite rate. Results Annual IRS with Actellic® CS between 2015 and 2017 was effective on sprayed walls for a mean of 7 months in cone bioassay. PCR of 2016 and 2017 samples showed vector populations were predominantly An. arabiensis (58.1%, n=4,403 IRS sites, 58%, n=2,441 unsprayed sites). There was a greater proportion of An. funestus s.s. in unsprayed sites (20.4%, n=858) than sprayed sites (7.9%, n=595) and fewer An. parensis (2%, n=85 unsprayed, 7.8%, n=591 sprayed). Biting peaks of An. gambiae s.l. followed periods of rainfall occurring between October and April, but were generally lower in sprayed sites than unsprayed. In most sprayed sites, An. gambiae s.l. indoor densities increased between January and February, i.e. 10-12 months after IRS. Based on these data and malaria case data, the timing of IRS was changed to November in Kagera and Geita Regions in 2018. The predominant species An. arabiensis had a sporozoite rate in 2017 of 2.0% (95% CI: 1.4-2.9) in unsprayed sites compared to 0.8% (95% CI: 0.5-1.3) in sprayed sites (p=0.003). Sporozoite rates also appeared to be lower for An. funestus collected in sprayed sites. Conclusion IRS appeared to have substantial impact on malaria transmission, with sporozoite rate in An. arabiensis being 59% lower in sprayed sites than in unsprayed sites in 2017.

Abstract
Background: The average number of accidents in professional drivers is higher than other drivers. These people's driving safety culture is likely different from others. Since there is little evidence about taxi drivers' safety culture, the emergence of related factors is valuable to be explored as a basic model. Therefore, the present study aimed at providing a model for explaining the affecting factors of the taxi drivers' safety culture in Iran based on Grounded Theory (GT).Method: This research was exploratory research aimed at explaining the factors affecting the safety culture of taxi drivers in Iran (Zanjan) and presenting a theoretical model. To this end, 26 IDIs were conducted with 12 taxi drivers and 14 others that were directly or indirectly involved with taxi drivers who were selected by theoretical sampling. Furthermore, in order to validate the themes resulted from the study and to gain a deeper understanding, an FGD containing six taxi drivers was held. According to the process suggested by Corbin and Strauss, the grounded theory method was used to interpret the collected data.Results: The results of this study brought SEL-SB model based on five emerged themes for the safety culture of taxi drivers, including stewardship and governance, law manifestation, socio-cultural profile, economic pressure, and safe behaviors. The axial theme of stewardship and governance was quite prominent. Participants emphasized factors such as the need for increased management commitment, cross-sectoral collaboration among traffic-related organizations, and quality of public transport services.Conclusion: Improving the driving behaviors of taxi drivers calls for understanding the way how they perceived traffic safety culture around them. The SEL-SB model emphasizes the need to dramatically organizational changes in the traffic-related organization in order to taxi drivers’ safety culture.

Abstract
Background: For over ten years, dental cellulitis management is not so longer simple: more and more patients need long-time hospitalization, several surgical interventions and intensive care follow-up. This prospective study seeks to highlight criteria that can split patients with severe odontogenic infection into two main groups: those with simple evolution after treatment of the infection and those for whom complex management is necessary to obtain healing.Methods: All patients with severe odontogenic infection (namely patients which necessitated hospital admission, intravenous antibiotherapy and general anesthesia) were prospectively recorded between January 2004 and December 2014. Statistical tests used were: chi-square test (or Fisher’s exact test when appropriate) for categorical data, and Student t-test (or Mann & Withney test when appropriate) for continuous data; statistics were computed with STATA V12 (Stata Corp, College Station, Texas, USA) and with R (R version 3.0.2; The R Foundation for Statistical Computing, Vienna, Austria; http://www.r-project.org).Results: A total of 653 patients were included in the study, 611 (93.6%) had one surgery, 42 (6.4%) had more than one surgery (range 2 – 15 surgeries) before healing. In multivariate analysis, objectives criteria which emerge are: C-reactive protein (CRP) level (CRP>200 mg/l, p=0.01, OR=4.12 IC95%=[1.33-12.72]), alcohol abuse (p=0.03, OR=2.70 IC95%=[1.09-6.7]), penicillin allergy (p=0.001, OR=5.47 IC95%=[1.99-15-09]), mandibular molar infection (p= 0.02, OR=2.74 IC95%=[1.16-6.48]). A conditional inference tree (CTREE) illustrated the association of prognostic factors and the need of multiple surgery. Conclusion: Four subgroups of patients with severe odontogenic infection have a relative risk range between 25 % and 33% to have several surgical intervention associated with complications as intensive unit care follow-up, tracheotomy or death: 1- patients with CRP>200 mg/l; 2- patients with CRP between 50 and 200 mg/l and penicillin allergy; 3- patients with CRP between 50 and 200 mg/l, without penicillin allergy but with molar mandibular infection and psychiatric disorders; 4- patients with CRP ≤ 50 mg/l or unknown CRP level and immunodepression.IRB number: CE-CIC-GREN-12-08

Abstract
Background:This study was undertaken to investigate the utility of 123I-ioflupane (123I-FP-CIT) single photon emission computed tomography (SPECT), 123I-metaiodobenzylguanidine (123I-MIBG) scintigraphy and both of these to differentiate among progressive supranuclear palsy (PSP), including typical cases and other subtypes, and Parkinson’s disease (PD).Methods: Twenty-five patients with typical PSP (Richardson's syndrome; PSP-RS), 14 atypical ones (PSP-variants; PSP-V) and 42 PD who underwent both 23I-FP-CIT SPECT and 123I-MIBG scintigraphy within short intervals were enrolled. Speciﬁc binding ratio (SBR) of the striatum and midbrain and anteroposterior and asymmetry ratio of the striatal SBR on 123I-FP-CIT SPECT and heart-to-mediastinum (H/M) ratio and washout rate (WR) on 123I-MIBG scintigraphy were used as quantitative measures. The classifier performance based on adaptive boosting was evaluated using five-fold cross-validation for these measures.Results: Midbrain SBR and the striatal anteroposterior ratio were statistically lower in PSP-RS than PD. On the other hand, there were no significant differences in any other quantitative measures among PSP-RS, PSP-V and PD. Striatal and midbrain SBRs and anteroposterior ratio of PSP-V were approximately in-between those of PSP-RS and PD. PD showed the lowest early and delayed H/M ratios and highest WR of any group. The combination of 123I-FP-CIT and 123I-MIBG was useful in discriminating PSP-RS and PSP-V from PD, while 123I-FP-CIT was superior to 123I-MIBG in differentiating PSP-RS from PSP-V.Conclusion: The combination of 123I-FP-CIT SPECT and 123I-MIBG scintigraphy, rather than either alone, may be a useful differential diagnostic tool to differentiate patients with PSP-RS, PSP-V and PD.

Abstract
Background:Someneuropsychological diseases are associated with abnormal thiamine metabolism, including Korsakoff-Wernicke syndrome and Alzheimer’s disease. However, in vivo detection of brain thiamine metabolism status isstill unavailable and needs to be developed.Methods:A novel PET tracer 18F-labeled thiaminewasautomatically radio-synthesized via a two-step route. The main parameters of characterization were proved by high performance liquid chromatography (HPLC). Metabolic kinetics of 18F-labeled thiamine and the status of cerebral thiamine uptakein mice and marmosets were studied by micro-positron emission tomography (PET)/computer tomography imaging. Also, in vivo stability, renal excretion rate, biodistribution, and the correlation between cerebral 18F-labeled thiamine retention and blood thiamine levels were investigated.Results: The 18F-labeled thiamine was stableboth in vitro and in vivoand manifested fast uptake and clearance in vivo. The biodistribution of 18F-labeled thiamine were consistent with previously reports on thiamine distribution in mice. The retention of cerebral 18F-labeled thiamine was higher in mice with thiamine deficiency than that in control mice, and negatively correlated with blood thiaminediphosphate levels in marmosets.Conclusion:The 18F-labeled thiamine met the requirements for ideal PET tracer to in vivoevaluate the status of cerebral thiamine metabolism. This study laid the foundation for further studies on the relevant diseases.

Abstract
Background Inadequate sleep hygiene (SH) is considered one the factors contributing to insomnia, including comorbid insomnia with mental disorders. However, the practice of SH by depressed patients with comorbid insomnia has not been explored. We aimed to compare the practice of SH between patients with major depression with comorbid insomnia, primary insomnia, and good sleepers. Methods One hundred and eighty-two adult individuals participated: 62 outpatients with major depressive disorder with comorbid insomnia (MDD), 56 outpatients with primary insomnia (PI), and 64 good sleepers (GS). All participants were assessed with a structured psychiatric interview, an insomnia interview, the Pittsburgh Sleep Quality Index, the Insomnia Severity Index and the Sleep Hygiene Practice Scale. We compared the practice of SH as a whole and by domains between the groups and the relation between SH practice, insomnia and sleep quality. Results Patients with PI and MDD showed a significantly worse practice of global SH. In the comparison by SH domains, MDD and PI groups had significantly higher scores than GS in all domains; individuals with MDD showed a significantly worse practice of sleep schedule and arousal related behaviors than PI group. SH practice was significantly related with insomnia and sleep quality in the whole sample, however only in the PI this association remained significant. Arousal-related behaviors domain was the main predictor of insomnia and sleep quality. Conclusions Although patients with insomnia comorbid with MDD or with PI have a worse SH practice than GS, only arousal-related behaviors and drinking/eating habits contribute significantly to insomnia severity and sleep quality.

Abstract
Background

Head and neck cancers are aggressive epithelial tumors and well recognized as a particularly challenging class of tumors to treat. Comprehensive molecular profiling is leading to the development of “personalized” or “precision” medicine. Here we report the genomic profiling of Chinese head and neck cancers and the incidence of NTRK aberrations.
Methods

We retrospectively analyzed the genetic aberrations in 127 patients of Chinese head and neck cancer. All the patients were detected by 1021-gene panel (including NTRK1, NTRK2, NTRK3) of hybridization capture-based next-generation sequencing with tumor tissue and matched peripheral blood control samples.
Results

This studied was inspired by the outcome benefit of a parotid cancer patient harboring ETV6-NTRK3 fusion, who received crizotinib treatment and achieved a 2-year progression-free survival (PFS). Then, we reviewed 127 cases of head and neck cancer in our database. The most common histology type was HNSCC (79.5%). The genomic profiling indicated that both in our Chinese cohort and TCGA database, TP53 is the most frequently mutated gene in head and neck cancer. The incidence of NTRK genetic aberrations was 7.9% (10/127) including NTRK fusion (n = 4, 3.1%) and NTRK mutation (n = 6, 4.7%). The most common fusion was ETV6-NTRK3 (n = 3, 2.4%). Compared to NTRK-wt group, NTRK aberration group had more APC and PTPRD aberrations (p < 0.05). The association of genetic aberrations with tumor mutation burden (TMB) had been analyzed. NTRK fusion-group had a lower TMB compared to the NTRK-wt group (p = 0.034). TP53 and LRP1B showed significant association with higher TMB (both p < 0.01), which may be potential markers of immunotherapy in head and neck cancer patients.
Conclusions

Our data is the first study to report the genomic profiling in Chinese head and neck cancers and the incidence of NTRK fusion. About 3% of Chinese head and neck patients may benefit from targeted therapy of NTRK inhibitors. An ETV6-NTRK3 fusion patient reached a long-term response with crizotinib treatment,indicating crizotinib might be an alternative treatment option for patients with NTRK fusions.

Abstract
Background: Oral squamous cell carcinoma (OSCC) has a high incidence of metastasis. Tumor immunotherapy targeting programmed death ligand 1 (PD-L1) or programmed cell death protein 1 (PD-1) is revolutionary; however, only a few patients with OSCC respond to this treatment. Therefore, it is necessary to understand the molecular mechanisms of OSCC growth and metastasis to identify new therapeutic targets. Methods: In this study, we first analyzed the expression level of protein kinase D3 (PKD3) and PD-L1, and their correlation with mesenchymal and epithelial markers through UALCAN database, UCSC Xena, western blot, and immunostaining of human OSCC tissue sections. We knocked down and overexpressed PKD3 in OSCC cell lines and analyzed cell growth, migration, and invasion using western blot, cell proliferation assays, wound healing assays, and Transwell assays. A mouse footpad xenograft model was used to study the effects of PKD3 on tumor growth and lymph node metastasis in vivo. Results: The expression of PKD3 and PD-L1 in OSCC cells and tissues was significantly increased, and correlated positively with mesenchymal markers but negatively with epithelial markers. Silencing PKD3 significantly inhibited the growth, metastasis, and invasion of OSCC cells, while its overexpression promoted these processes. PKD3 regulated PD-L1 expression through the ERK/STAT1/3 signaling pathway, forming a positive feedback regulatory loop with PD-L1 to induce epithelial-mesenchymal transition (EMT) in OSCC. Conclusions: There is a positive feedback regulation between PKD3 and PD-L1, which can drive the EMT of OSCC cells through the ERK/STAT1/3 pathway, thereby promoting tumor growth and metastasis. Our findings provide a theoretical basis for targeting PKD3 as an alternative method to block EMT for regulating PD-L1 expression and inhibiting OSCC growth and metastasis . Keywords: OSCC, PKD3, PD-L1, EMT, tumor growth, metastasis

Published: May 2020

Abstract
Background: Electrocardiogram (ECG) is widely used to screen cardiac diseases. To date, no large population study has provided estimates of the prevalences of ECG findings in China. We aim to investigate the prevalences and risk factors of ECG abnormalities in the general population of Chinese adults.Methods: ECG data were obtained from 34965 participants in the 2007-2008 China National Diabetes and Metabolic Disorders Study. ECG abnormalities were classified according to the Minnesota coding (MC) criteria. Prevalences of variant ECG abnormalities were calculated. The associations between ECG abnormalities and gender, age and other risk factors for cardiovascular diseases (CVD) were analyzed by multivariate logistic regression test.Results: The prevalences of major arrhythmias were 1.70%, 2.37% and 1.04% in the whole population, men and women, respectively. Atrial fibrillation/flutter was found in 0.35% of men and 0.20% of women. ST depression and T abnormalities accounted for 10.96%, 7.54% and 14.32% in the whole population, men and women, respectively. Independent of gender and other CVD risk factors, the older age significantly increased the risk of having atrial fibrillation/flutter, complete left bundle branch block, complete right bundle branch block, sinus tachycardia, atrial/junctional/ventricular premature beats, ST depression and T abnormalities, tall R wave left, left/right atrial hypertrophy, left axis deviation and low voltage. Hypertension, overweight, obesity and hypercholesterolemia all independently increased the odds ratios of having ST depression and T abnormalities. History of cardiovascular/cerebrovascular diseases was positively associated with major arrhythmias, ST depression and T abnormalities and tall R wave left.Conclusions: This study provides estimates of the prevalences of ECG findings in a large population of Chinese adults. Gender, age, CVD risk factors and history of cardiovascular/cerebrovascular diseases had important impact on ECG abnormalities.# Liping Yu and Xiaojun Ye contributed equally to this work.

Abstract
BackgroundVisuospatial working memory (VSWM) impairments were common in Autism Spectrum Disorder (ASD). However, the detailed processing characteristics when facing face stimuli has not been studied. The present study aimed to explore the deficits of face encoding and retrieving, two processing periods of VSWM, in children with ASD. Furthermore, the influence of comorbid with Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms and executive function (EF) on VSWM were discussed.MethodsA sample of 98 children were analyzed in the present study including ASD- (ASD-only, n = 24), ADHD (n = 23), ASD+ (with ADHD symptoms, n = 23) and neurotypical controls (NTC, n = 28). Social Responsive Scale (SRS) and Swanson, Nolan, Pelham-IV rating scales (SNAP-IV) were applied to measure autistic and ADHD-related symptoms. We employed face encoding and retrieving task to examine the ability of VSWM as well as Wisconsin Cart Sorting Test (WCST) to assess the EF.ResultsWe found that the children with ASD- exhibited lower accuracy in both face encoding and retrieving, while subjects with ASD + showed lower accuracy in the face retrieving. No evidence implied a deficit of VSWM in ADHD group. We also found diverse indices of EF contributed to the individuals’ differences of VSWM performance in different clinical groups: categories completed (CC) predicted the accuracy of face retrieving in ASD- group; perseverative responses errors (RPE) predicted the response time (RT) of face retrieving in ADHD and ASD + group; while failure to maintain set (FMS) and RPE predicted the RT of face encoding in ASD + group.LimitationsThe sample size is still small and the sample mainly comprised of intellectually able participants. Therefore, our findings should not be overinterpreted.ConclusionOur findings indicate that comorbid with ADHD symptoms and EF may modulate the deficit of face encoding in children with ASD. The study shed lights on the transdiagnostic neurocognitive basis and re-emphasize the importance of considering ADHD-comorbid condition in ASD.Qi Chen and Zengjian Wang contributed equally to this work as the joint first authors.

Abstract
BackgroundThe supportive hospice aged residential Exchange (SHARE) is a new model of palliative care education that has been designed for residential aged care. The goal of SHARE is to help clinical staff improve palliative care within residential aged care facilities and to improve specialist palliative care nurses' knowledge and skill to care for frail older people.MethodThe experiences of 16 bereaved families concerning the palliative care journey (both at the start and finish of a one-year implementation of SHARE) were explored using semi-structured interviews.ResultsFour themes were important to bereaved families’ experience: communication with staff, relationship with general practitioners, systems of care, and hospice involvement. A sub-theme indicating changes in these four components of care between the start and finish of SHARE was identified. A fifth theme highlighted challenges (staff shortages and turnover).ConclusionFindings indicated that SHARE benefited families (improved communication and support) through the end of life journey of their relatives, but challenges remained.
