Abstract
Background: Certain species of macaques are natural hosts of Plasmodium knowlesi and P. cynomolgi, which can both cause malaria in humans, and P. inui, which can be experimentally transmitted to humans. A significant number of zoonotic malaria cases have been reported in humans throughout Southeast Asia, including Thailand. There have been only two studies undertaken in Thailand to identify malaria parasites in non-human primates in 6 provinces. The objective of this study was to determine the prevalence of P. knowlesi, P. coatneyi, P. cynomolgi, P. inui and P. fieldi in non-human primates from 4 new locations in Thailand. Methods: A total of 93 blood samples from Macaca fascicularis, M. leonina and M. arctoides were collected from four locations in Thailand: 32 were captive M. fascicularis from Chachoengsao Province (CHA), 4 were wild M. fascicularis from Ranong Province (RAN), 32 were wild M. arctoides from Prachuap Kiri Khan Province (PRA), and 25 were wild M. leonina from Nakornratchasima Province (NAK). DNA was extracted from these samples and analysed by nested PCR assays to detect Plasmodium, and subsequently to detect P. knowlesi, P. coatneyi, P. cynomolgi, P. inui and P. fieldi.Results: Twenty-seven of the 93 (29%) samples were Plasmodium-positive by nested PCR assays. Among wild macaques, all 4 M. fascicularis at RAN were infected with malaria parasites followed by 50% of 32 M. arctoides at PRA and 20% of 25 M. leonina at NAK. Only 2 (6.3%) of the 32 captive M. fascicularis at CHA were malaria-positive. All 5 species of Plasmodium were detected and 16 (59.3%) of the 27 macaques had single infections, 9 had double and 2 had triple infections. The composition of Plasmodium species in macaques at each sampling site was different. Macaca arctoides from PRA were infected with P. knowlesi, P. coatneyi, P. cynomolgi, P. inui and P. fieldi. Conclusions: The prevalence and species of Plasmodium varied among the wild and captive macaques, and between macaques at 4 sampling sites in Thailand. Macaca arctoides is a new natural host for P. knowlesi, P. inui, P. coatneyi and P. fieldi.

Abstract
Background: Previous studies of diabetes among armed forces personnel did not assess a comprehensive disease prevalence. We conducted a systematic review and meta-analysis to estimate the prevalence of type 2 diabetes and prediabetes among the military personnel and police officers. Methods: We carried out a systematic search on electronic databases from January 2000 to July 2020. All studies with a report of the prevalence of diabetes and/or prediabetes among armed forces personnel were selected. However, studies with inappropriate population, estimation of incidence, and non-English language were excluded. The Cochran test and I2 statistics were used to determine the heterogeneity of the studies. Random- or fixed-effects model, along with subgroup analysis on diabetes or prediabetes as well as the component of armed forces, was carried out to determine the overall prevalence. All analyses were conducted using STATA software. Results: Among 858 citations, 30 studies were entered into the meta-analysis, involving 1879170 individuals. The meta-analysis estimated the prevalence of type 2 diabetes among the military personnel (9.15%; CI: 5.35-12.96) and police officers (9.58%; 95% confidence intervals [CI]: 5.98-13.18). The overall prevalence of prediabetes among the military personnel and the police officers were 7.32% (CI: 4.22-10.42) and 6.39% (CI: 4.54-8.23), respectively. Conclusion: The prevalence of diabetes and prediabetes among armed forces were consistent with global reports among general population. These results will inform policy-makers and healthcare providers to find solutions, and help to take action to reduce diabetes risk factors on a wider scale, particularly among armed forces personnel.
Imbalance of laminar-specific excitatory and inhibitory circuits of the orbitofrontal cortex in autism
Authors: Liu Xuefeng , Bautista Julied , Liu Edward , Zikopoulos Basilis 
Published: September 2020

Abstract
Background: The human orbitofrontal cortex (OFC) is involved in assessing the emotional significance of events and stimuli, emotion-based learning, allocation of attentional resources, and social cognition. Little is known about the structure, connectivity and excitatory/inhibitory circuit interactions underlying these diverse functions in human OFC, as well as how the circuit is disrupted in individuals with autism spectrum disorder (ASD).Methods: We used post-mortem brain tissue from neurotypical adults and individuals with ASD. We examined the morphology and distribution of myelinated axons across cortical layers in OFC, at the single axon level, as a proxy of excitatory pathways. In the same regions, we also examined the laminar distribution of all neurons and neurochemically- and functionally-distinct inhibitory neurons that express the calcium-binding proteins parvalbumin (PV), calbindin (CB), and calretinin (CR). Results: We found that the density of myelinated axons increased consistently towards layer 6, while the average axon diameter did not change significantly across layers in both groups. However, both the density and diameter of myelinated axons were significantly lower in the ASD group compared with the Control group. The distribution pattern and density of the three major types of inhibitory neurons was comparable between groups, but there was a significant reduction in the density of excitatory neurons across OFC layers in ASD. Limitations: This study is limited by the availability of human post-mortem tissue optimally processed for high-resolution microscopy and immunolabeling, especially from individuals with ASD. Conclusions: The balance between excitation and inhibition in OFC is at the core of its function, assessing and integrating emotional and social cues with internal states and external inputs. Our preliminary results provide evidence for laminar-specific changes in the ratio of excitation/inhibition in OFC of adults with ASD, with an overall weakening and likely disorganization of excitatory signals and a relative strengthening of local inhibition. These changes likely underlie pathology of major OFC communications with limbic or other cortices and the amygdala in individuals with ASD, and may provide the anatomic basis for disrupted transmission of signals for social interactions and emotions in autism.

Abstract
Background: Evaluation of the resting energy expenditure (REE) is essential to ensure an appropriate dietary prescription for patients with type 2 diabetes. The aim of this record was to evaluate the accuracy of predictive equations for REE estimation in patients with type 2 diabetes, considering indirect calorimetry (IC) as the reference method.Methods: A cross-sectional study was performed in outpatients with type 2 diabetes. Clinical, body composition by electrical bioimpedance and laboratory variables were evaluated. The REE was measured by IC (QUARK RMR, Cosmed, Rome, Italy) and estimated by eleven predictive equations. Data were analyzed using Bland–Altman plots, paired t-tests, and Pearson’s correlation coefficients.Results: 62 patients were evaluated [50% female; mean age 63.1 ± 5.2 years; diabetes duration of 11 (1-36) years, and mean A1C of 7.6 ± 1.2%]. There was a wide variation in the accuracy of REE values predicted by equations when compared to IC REE measurement. In all patients, Ikeda and Mifflin St-Jeor equations were that most underestimated REE. And, the equations that overestimated the REE were proposed by Dietary Reference Intakes and Huang. The most accurate equations were FAO/WHO/UNO in women (-1.8% difference) and Oxford in men (-1.3% difference).Conclusion: In patients with type 2 diabetes, in the absence of IC, FAO/WHO/UNO and Oxford equations provide the best REE prediction in comparison to measured REE for women and men, respectively.

Abstract
Background: Obesity is a globally increasing health epidemic requiring early lifestyle intervention. Our main objective was to examine the effectiveness of companion-intensive multi-aspect weight management (CIMWM) in Chinese adults with obesity.Methods: In this 6-month, prospective, open-label, multicenter, randomized controlled clinical trial, we recruited 272 obese adults aged 18–50 years with a body mass index (BMI) ≥28.0 kg/m2 and capable of using smartphones. CIMWM (n=136) offered both daily online instructions and monthly face-to-face guidance by physicians, dietitians, and health managers along with the provision of meal replacements in the first 3 months. Traditional multi-aspect weight management (TMWM, n=136) provided monthly face-to-face guidance by the same panel of professionals and the same meal replacements as CIMWM group, but required subjects to complete daily self-monitoring instead of offering daily online instructions. Body composition and metabolic parameters were assessed at baseline, 1, 2, 3, and 6 months by physicians. Primary outcomes were the clinically-significant weight loss and changes in BMI and body composition.Results: Participants in both groups showed significantly reduced BMI, body fat mass (BFM), visceral fat area (VFA), and HOMA-IR (P<0.05). CIMWM was shown to be superior to TMWM in the improvement of clinically-significant weight loss, BMI, total cholesterol (TC), the body composition parameters BFM and the skeletal muscle mass-to-visceral fat area ratio (S/V) (P<0.05). The non-alcoholic fatty liver disease score (NFS) was negatively related to S/V at baseline. After weight management, NFS was lowered among individuals with levels in the highest tertile (P<0.05). Metabolic memory in terms of the continuous reduction of BMI, BFM, and TC was retained up to 6 months in spite of participants transferring to self-monitoring assessment in the final 3 months.Conclusions: The CIMWM strategy in obese Chinese adults is proved to be more effective than TMWM in weight loss, and motivates greater adherence to intervention and lifestyle reprogramming.Trial registration: Chinese Clinical Trial Registry, ChiCTR1800017463, Registered July 31, 2018, retrospectively registry. http://www.chictr.org.cn/showproj.aspx?proj=29649

Published: September 2020

Abstract
Background: The current rapid prevalence of the novel coronavirus (COVID-19) pandemic over the world is associated with a considerable level of scared, anxiety and panic among the public, in particular, healthcare providers (HCPs) as the most vulnerable group at risk for SARS-CoV-2 infection. To protect and enhance HCPs' capacity to carry out their duties in responding to COVID-19, healthcare authorities should keep them away from stress and anxiety and improve their knowledge, attitude, and practice towards COVID-19 to ensure their compliance to infection control precautions. Therefore, this study aimed to explore knowledge, attitudes, anxiety, and preventive behaviours among Yemeni HCPs towards COVID-19. Methods: A descriptive, web-based-cross-sectional study was conducted among a number of 1231 Yemeni HCPs. The COVID-19 related questionnaire was designed using Google forms. The responses were coded and analysed using the software package (IBMSPSS), version 22.0. Descriptive statistics and Pearson's correlation coefficient test were also used in this study. A p-value of < 0.05 levels with a 95% confidence interval was considered as statistically significant.. The data collection started on 22nd April 2020, at 6 PM and closed on 26th April 2020 at 11 AM. Results: The results indicated that out of 1231 of the HCPs participating in this study, 61.6% were male and 67% were in the age group of 20 to 30 years old with a mean of 29.29±6.75. Most of them (86%) had a bachelor degree or above and had 10 years of working experience or less (88.1%). Besides, although 57.1% of the respondents obtained their information via social and news media and 60.0% had never attended lectures/discussions about COVID-19, the results revealed that the majority of respondents had an adequate level of knowledge, an optimistic attitude, moderate anxiety and high performance in preventive behaviors (69.8%, 85.10%, 51.0& 87.70%, respectively) toward the COVID-19 pandemic. Conclusion: Although the Yemeni HCPs exhibited an adequate level of knowledge, an optimistic attitude, moderate anxiety and high performance in preventive behaviours toward the COVID-19 pandemic, the results showed gaps in some themes, particularly in their knowledge and attitude on COVID-19 pandemic which need to be updated or refreshed.

Abstract
ABSTRACTBackground: In Malawi, numerous barriers may prevent women from accessing cervical cancer screening services — including social factors such as male partner involvement. We conducted surveys that included open- and closed-ended questions with married Malawian men to evaluate their knowledge and beliefs about cervical cancer. Methods: HIV-positive adult (≥18 years) men (married or in a stable relationship) were recruited from an antiretroviral therapy clinic in Lilongwe, Malawi. Men were asked a series of survey questions to assess their knowledge about cervical cancer, experience with cervical cancer, their female partner’s screening history, and their beliefs about gender norms and household decision-making. Following the survey, participants responded to a set of open-ended interview questions about cervical cancer screening, and men’s role in prevention.Results: 120 men were enrolled with average age 44 years and 55% having completed secondary school or higher education. Despite only moderate knowledge about cervical cancer and screening (average assessment score of 62% correct), all men expressed support of cervical cancer screening, and most (86%) believed they should be involved in their female partner’s decision to be screened. Over half (61%) of men said their female partner had ever previously been screened for cervical cancer, and this was positively correlated with the male respondent having more progressive gender norms around sexual practices. Some men expressed concerns about the screening process, namely the propriety of vaginal exams when performed by male clinicians, and whether the procedure was painful.Conclusions: Male partners in Malawi want to be involved in decisions about cervical cancer screening, but have limited knowledge about screening, and hold rigid beliefs about gender norms that may affect their support for screening. Messaging campaigns addressing men’s concerns may be instrumental in improving women’s adoption of cervical cancer screening services in Malawi and similar settings.

Published: September 2020

Abstract
Background: Pomelo is one of the three major species of citrus. The fruit accumulates a variety of abundant secondary metabolites that affect the flavor. UDP-glycosyltransferases (UGTs) are involved in the glycosylation of secondary metabolites. Results: In the present study, we performed a genome-wide analysis of pomelo UGT family, a total of 145 UGTs was identified based on the conserved plant secondary product glycosyltransferase (PSPG) motif. These UGT genes were clustered into 16 major groups through phylogenetic analysis of these genes with other plant UGTs (A-P). Pomelo UGTs were distributed unevenly among the chromosomes. At least 10 intron insertion events were observed in these UGT genome sequences, and I-5 was identified to be the highest conserved one. The expression profile analysis of pomelo UGT genes in different fruit tissues during development and ripening was carried out by RNA-seq. Conclusions: We identified 145 UGTs in pomelo fruit through transcriptome data and citrus genome database. Our research provides available information on UGTs studies in pomelo, and provides an important research foundation for screening and identification of functional UGT genes.

Abstract
Background: Triggering receptor expressed on myeloid cells 2 (TREM2) is expressed in the brain exclusively on microglia and genetic variants are linked to neurodegenerative diseases including Alzheimer’s disease (AD), frontotemporal dementia (FTD) and Nasu Hakola Disease (NHD). The Trem2 variant R47H, confers substantially elevated risk of developing late onset Alzheimer’s disease, while NHD-linked Trem2 variants like Y38C, are associated with development of early onset dementia with white matter pathology. However, it is not known how these Trem2 species, predisposes individuals to presenile dementia.Methods: To investigate if Trem2 Y38C or loss of Trem2 alters neuronal function we generated a novel mouse model to introduce the NHD Trem2 Y38C variant in murine Trem2 using CRISPR/Cas9 technology. Trem2Y38C/Y38C and Trem2-/- mice were assessed for Trem2 expression, differentially expressed genes, synaptic protein levels and synaptic plasticity using biochemical, electrophysiological and transcriptomic approaches.Results: While mice harboring the Trem2 Y38C exhibited normal expression levels of TREM2, the pathological outcomes phenocopied Trem2-/- mice at 6 months. Transcriptomic analysis revealed altered expression of neuronal and oligodendrocytes/myelin genes. We observed regional decreases in synaptic protein levels, with the most affected synapses in the hippocampus. These alterations were associated with reduced synaptic plasticity. Conclusion: Our findings provide in vivo evidence that Trem2 Y38C disrupts normal TREM2 functions. Trem2Y38C/Y38C and Trem2-/- mice demonstrated altered gene expression, changes in microglia morphology, loss of synaptic proteins and reduced hippocampal synaptic plasticity at 6 months in absence of any pathological triggers like amyloid. This suggests TREM2 impacts neuronal functions providing molecular insights on the predisposition of individuals with TREM2 variants resulting in presenile dementia.

Abstract
Background: To investigate the clinical characteristics of Epstein–Barr virus (EBV) infection in the pediatric nervous system (NS). Methods: We retrospectively analyzed the clinical data and follow-up results of 89 children with neurological damage caused by EBV who were hospitalized in the children's hospital of Chongqing Medical University from January 2008 to April 2019. Results: EBV infection of the NS can occur at any time of the year. The highest incidence was seen in the age group of 0–4 years. Fever is the main clinical feature (74/89, 83.1%). The main clinical types were encephalitis/meningoencephalitis (64/89, 71.9%), acute myelitis (2/89, 2.2%), acute disseminated encephalomyelitis (ADEM) (3/89, 3.4%), Guillain–Barré Syndrome (GBS) (15/89, 16.9%), neurological damage caused by EBV-hemophagocytic lymphohistiocytosis (EBV-HLH) (4/89, 4.5%), and NS-post-transplant lymphoproliferative disorder (NS-PTLD) (1/89, 1.1%). Anti-N-methyl-D-aspartate receptor encephalitis was found during the convalescence of EBV encephalitis. EBV encephalitis/meningitis showed no symptoms of tonsillitis, lymph node enlargement, skin rash, hepatosplenomegaly. Acute motor axonal neuropathy is the chief complication in GBS caused by EBV. Conclusion: There were significant differences in neurological complications caused by EBV. The prognosis of EBV infection in the NS is generally good. These illnesses are often self-limiting. A few cases may show residual sequelae.

Abstract
Background We aimed to develop and validate a nomogram incorporating CA125 levels after three cycles of chemotherapy for predicting progression-free survival (PFS) in patients with ovarian cancer.Methods The nomogram was developed in a primary cohort of 491 patients with stage II-IV ovarian cancer. Performance was assessed by concordance index (C-index), calibration curve, and decision curve analysis, and compared with the International Federation of Gynecology and Obstetrics (FIGO) staging system. The predictive value of CA125 levels after three cycles of chemotherapy was evaluated. The model was subjected to bootstrap internal validation. An independent cohort of 81 patients was used for external validation.Results CA125 levels after three cycles of chemotherapy were significantly associated with PFS. Five variables, including CA125 levels were selected to develop the nomogram. The nomogram demonstrated adequate discrimination, with a bootstrap-corrected C-index of 0.708, and good calibration. External validation of the nomogram achieved excellent discrimination (C-index, 0.724) and calibration. CA125 levels after three adjuvant chemotherapy cycles showed a marginally significant increment of discrimination to the nomogram in the primary cohort (C-index, 0.708 vs 0.668; P = 0.097). Superior discriminative ability was observed in the nomogram when compared with the FIGO staging system only in the primary cohort (C-index, 0.708 vs 0.578; P < 0.001). Decision curve analysis demonstrated that our nomogram was clinically useful.Conclusion We developed and validated a nomogram incorporating CA125 levels after three chemotherapy cycles for PFS prediction in ovarian cancer. This nomogram showed well-predictive performance and easy clinical application.
