Authors: Lee Hyun , Choe Yeong Hun , Park Seung Yong 
Published: November 2019

Abstract
Background: There are limited data regarding the efficacy and safety of remifentanil sedation for diagnostic bronchoscopy. Methods: A retrospective study of 186 patients who underwent diagnostic bronchoscopy at Chonbuk National University Hospital was performed. Patients were classified into the remifentanil group and midazolam/propofol group according to the drugs used during bronchoscopy. The aim of this study was to evaluate the clinical efficacy and safety of remifentanil by comparing it with those of conventional drugs, midazolam and propofol. Results: Of the 186 patients, 111 patients received remifentanil and 75 received midazolam/propofol during the bronchoscopy. The proportion of patients who required bronchoscopy for endobronchial inspection alone was significantly higher in the midazolam/propofol group than in the remifentanil group (93.3% vs. 71.2%; p < 0.001). In contrast, the proportion of patients who required more invasive procedures, such as bronchoscopic biopsy, bronchoalveolar lavage, or transbronchial lung biopsy, was significantly higher in the remifentanil group than in the midazolam/propofol group (27.8% vs. 6.7%; p < 0.001). The recovery time was significantly shorter in the remifentanil group than in the midazolam/propofol group (mean 6.4 min vs. 11.6 min, p < 0.001). There was no significant difference between the groups with regard to safety events including desaturation, hypotension, and arrhythmia. Conclusions: Despite the higher proportion of patients who underwent more invasive procedures in the remifentanil group than in the midazolam/propofol group, there was no significant difference in safety events between the groups. Those in the remifentanil group also demonstrated a faster recovery time than those in the midazolam/propofol group.

Abstract
Background: Tuberculosis is a serious health threat, especially for people living with human immune deficiency virus worldwide and the burden of TB/HIV infection is still high in Ethiopia in particular. Objective: To determine the predictors of tuberculosis infection among adults visiting anti-retroviral treatment center in East and west Gojjam, Northwest Ethiopia, 2017Methods: An institution based unmatched case-control study was conducted in East and West Gojjam Zone, Northwest, Ethiopia from March 7-April 15, 2017. Cases were 139 tuberculosis infected human immune deficiency virus positives and controls were 413 non-TB infected HIV positives i.e. 1:3 proportion. All cases in each health facility who confirmed by acid-fast bacilli (direct microscopy), culture and gene expert were considered as TB positive fine needle aspiration. However controls were selected by using simple random sampling technique through the above diagnostic criteria and the data were collected with Face to face interview as well as patient medical record were used and the quality of the data were assured, checked, coded, cleaned and entered in EPI-Data version 3.1 and exported to SPSS version 20 for the analysis. Result: Of the total sample (556), just about 552(99.2%) were participated in the study among this 47.5% were females and 58.9% were rural. Behavioral and modifiable biological risk factors: alcohol users (AOR=2.33; 95% CI:1.34,4.07), BMI<18.5kg/m2 (AOR=3.03;95%CI:1.79,5.14), CD4 count ≤200 cells/µl (AOR=2.34;95%CI:1.89,2.79) and between 201-499 cells/µl (AOR=2.63; 95%CI: 1.01,6.84), bedridden and ambulatory (AOR=3.3;95%CI:1.70,6.29 and AOR=8.2;95%CI:4.34,15.64),respectively. TB history in the family (AOR=3.00; 95%CI: 1.57, 5.74) were predictors for TB infection. Taking CPT (AOR=0.36; 95%CI: 0.21, 0.62) and having early WHO clinical stage I or II (AOR=0.34; 95%CI: 0.20, 0.56) had protective effect against TB infection. Conclusion &Recommendation: Behavioral, biological, clinical and TB history in the family were highly prevalent in the study area. Strengthen screening more frequently, CPT Prophlaxysis and treated promptly important to reduce TB co-morbidity.

Published: November 2019

Abstract
After the circulation of H5N1 in 2006, 2015 and 2016 in Iraq, a new H5N8 influenza virus emerged in Iraq in 2018. In this study, a HPAI virus subtype H5N8 was identified from backyard domestic geese in Kurdistan region, Iraq. Phylogenic analyses of the hemagglutinin (HA) and neuraminidase (NA) genes indicated that Iraq H5N8 viruses belonged to clade 2.3.4.4 group B and clustered with isolates from Iran, Israel and Belgium. Genetic analysis of HA of the Iraq H5N8 indicated molecular markers for avian-type receptors. Characterization of the NA gene showed that the virus had sensitive molecular markers for antiviral drugs. This is the first study ever on H5N8 in Iraq and it is crucial to understand the epidemiology of the viruses in Iraq and the Middle East. The results are suggestive of a possible role of migratory birds in the introduction of HPAI subtype H5N8 into Iraq.

Abstract
A functionalized multiwalled carbon nanotube (MWCNT)-coated solid-phase microextraction (SPME) fiber was developed for concentrating analytes in aqueous samples. Sodium deoxycholate(NaDC) was used as a dispersing agent for non-covalent modification of MWCNTs. The coating was characterized by transmission electron microscope, scanning electron microscopy and infrared spectroscopy. It showed porous structure and had large adsorption capacity. To investigate the capability of this MWCNTs/NaDC SPME fiber, it was applied to the analysis of phenols in aqueous solution. After extraction, the analytes were desorbed in an acetonitrile–water solution and analyzed using high-performance liquid chromatography. The MWCNTs/NaDC fiber exhibited good analytical performance, and fine preparation reproducibility was obtained with the relative standard deviations (RSDs) ranging from 4.9% to 10.2% (n = 6) in one batch, from 5.7% to 11.9% (n = 3) among different batches. Under the optimum extraction conditions, the detection limits were 0.15–0.30 ng/mL(S/N=3), the linear detection ranges were 1–100 ng/mL (R2≥0.9997) for these analytes, and good recoveries(80.3%–95.4%) were obtained for the spiked samples. This is a simple and accurate pretreatment method for the analysis of phenols in aqueous samples.

Abstract
Background Mammalian X chromosomes are mainly euchromatic with a similar size and structure among species whereas Y chromosomes are smaller, have undergone substantial evolutionary changes and accumulated male specific genes and genes involved in sex determination. The PAR is conserved on the X and Y and pair during meiosis. The structure, evolution and function of mammalian sex chromosomes is still poorly understood because few species have high quality sex chromosome assemblies. Results Here we report the first bovine sex chromosome assemblies that include the complete pseudoautosomal region (PAR) spanning 6.84 Mb and three Y chromosome X-degenerate (X-d) regions. We show that the ruminant PAR comprises 31 genes and is similar to the PAR of pig and dog but extends further than those of human and horse. Differences in the pseudoautosomal boundaries are consistent with evolutionary divergence times. Conclusions A bovidae-specific expansion of members of the lipocalin gene family in the PAR may reflect immune-modulation and anti-inflammatory responses that contribute to parasite resistance in ruminants. Comparison of the X-d regions of Y chromosomes across species reveal five conserved X-Y gametologs, which are global regulators of gene activity, and may have a fundamental role in mammalian sexual dimorphism.

Abstract
Background Locally advanced breast cancer often undergoes neoadjuvant chemotherapy (NAC), which allows in vivo evaluation of the therapeutic response. The determination of the pathological complete response (pCR) is one way to evaluate the response to neoadjuvant chemotherapy. However, the rate of pCR differs significantly between molecular subtypes and the cause is not yet determined. Recently, the metabolic reprogramming of cancer cells and its implications for tumor growth and dissemination has gained increasing prominence and could contribute to a better understanding of NAC. Thus, this study proposed to evaluate the expression of metabolism-related proteins and its association with pCR and survival rates. Methods The expression of monocarboxylate transporters 1 and 4 (MCT1 and MCT4, respectively), cluster of differentiation 147 (CD147), glucose transporter-1 (GLUT1) and carbonic anhydrase IX (CAIX) was analyzed in 196 locally advanced breast cancer samples prior to NAC. The results were associated with clinical-pathological characteristics, occurrence of pCR, disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS). Results The occurrence of pCR was higher in the group of patients whith tumors expressing GLUT1 and CAIX than in the group without expression (27.8% versus 13.1%, p = 0.030 and 46.2% versus 13.5%, p = 0.007, respectively). Together with regional lymph nodes staging and mitotic staging, CAIX expression was considered an independent predictor of pCR. In addition, CAIX expression was associated with DFS and DSS (p = 0.005 and p = 0.012, respectively). Conclusions CAIX expression was a predictor of pCR and was associated with higher DFS and DSS in locally advanced breast cancer patients subjected to NAC.

Abstract
Background and Aims Endoscopic ultrasound is useful for obtaining high-resolution images of pancreaticobiliary diseases, but is not readily available for physical checkups. In this study, we evaluated the safety and efficacy of single-session esophagogastroduodenoscopy and endoscopic ultrasound in the detection of upper-gastrointestinal and pancreaticobiliary diseases using a forward-viewing radial scan ultrasonic endoscope. Methods A total of 148 patients who were scheduled for upper-gastrointestinal screening using an endoscope were prospectively included. All patients were examined by EUS in combination with EGD using a forward-viewing radial scan ultrasonic endoscope. The primary endpoint was the safety of the procedures. The secondary endpoints were the prevalence of diseases, the basal imaging capability of EUS, the procedure time, total dose of propofol, and the correlation between background factors and the prevalence of pancreatic disease. The imaging capability at each region was scored as 0 (invisible) to 2 (sufficient visualization to evaluate the organs). Results Intraoperative hypotension occurred as an adverse event of intravenous anesthesia in one patient. There were 82 pancreaticobiliary findings and 165 upper-gastrointestinal findings (malignancy not included). Follicular lymphoma of the intra-abdominal lymph nodes was detected in one patient. The mean imaging scores of each section were 1.95 (pancreatic head and papilla), 2.0 (pancreatic body), 1.99 (pancreatic tail), and 1.89 (common bile duct and gallbladder). Age, history of diabetes mellitus, and smoking history were significantly associated with the prevalence of pancreatic diseases. Conclusion The simultaneous performance of EGD and EUS using a new ultrasonic endoscope is tolerable and safe for upper-gastrointestinal and pancreaticobiliary screening.

Abstract
Background: Safe childbirth remains a daunting challenge, particularly in low-resource settings where most pregnancy-related deaths occur. Cameroon’s maternal mortality rate, estimated at 782 per 100,000 live births in 2011 is significantly high. Adherence to good practice standards by birth attendants is key to improving pregnancy outcomes. The WHO Safe Childbirth checklist was designed as a tool to improve the quality of care provided to women giving birth. This checklist was implemented at the Yaounde Gyneco-Obsteric and Pediatric Hospital. Quantitative and qualitative assessment of its utilization is essential to secure a change in attitudes and practice and engender improvement in maternal health. Objective: Evaluate the change in attitudes and practice of nurses and compare outcomes in cases where it was and was not used, 6 months after introduction of the safe childbirth checklist in a maternity setting. Methods: A cross sectional and retrospective study was conducted over a 6 month period (January – June 2018). Predesigned questionnaires were used to collect qualitative data on the checklist from personnel of the maternity and another data collection form used to extract information from patient records. Data analysis was done using SPSS version 23.0. Chi square test was used to compare categorical variables, while the student test was used to compare continuous variables. Results: Of the 1001 files retrieved from the archives, 25 were excluded. The checklist was used in 828/976 (84.8%) files. We observed an increasing trend in the usage rate, with a peak at 93.9% recorded during the last 2 months. Pages 2 and 3 were least completed, in <10% of cases during the first 5 months. Fewer cases of pre-eclampsia and eclampsia were associated with the use of the checklist, compared to patients in whom the checklist was not used (2·1% Vs 5·4%, p = 0·017). Fifty percent of the staff reported that the checklist increased workload while 37.5% mentioned laziness and absence of checklists in some files as a hindrance to its proper use. Conclusion: The use of the safe childbirth checklist improved progressively with a simultaneous reduction in obstetrical and neonatal complications overtime.

Abstract
Background: Parkinson’s disease (PD) and atypical parkinsonisms (APD) have overlapping symptoms challenging an early diagnosis. Diagnostic accuracy is important because PD and APD have different prognosis and response to treatment. We aimed to identify diagnostic inflammatory biomarkers of PD and APD in cerebrospinal fluid (CSF) using the multiplex proximity extension assay (PEA) technology and to study possible correlations of biomarkers with disease progression.

Methods: CSF from a longitudinal cohort study consisting of PD and APD patients (PD, n = 44; multiple system atrophy (MSA), n = 14; vascular parkinsonism (VaP), n = 9; and PD with VaP, n = 7) and controls (n = 25) were analyzed.

Results: Concentrations of CCL28 were elevated in PD compared to controls (p = 0.0001). Five other biomarkers differentiated both MSA and PD from controls (p < 0.05) and 10 biomarkers differentiated MSA from controls, of which two proteins, i.e. beta nerve growth factor (β-NGF) and Delta and Notch like epidermal growth factor-related receptor (DNER), were also present at lower levels in MSA compared to PD (both p = 0.032). Two biomarkers (MCP-1 and MMP-10) positively correlated with PD progression (rho > 0.650; p < 0.01).

Conclusions: PEA technique identified potential new CSF biomarkers to help to predict the prognosis of PD. Also, we identified new candidate biomarkers to distinguish MSA from PD.

Abstract
Background Due to its rapid lethal effect in the early development stage of shrimp, acute hepatopancreatic necrosis disease (AHPND) has been causing great economic losses, since its first outbreak in southeast China in 2009. Vibrio parahaemolyticus, carrying the pirA and pirB toxin genes is known to cause AHPND in shrimp. The overall objective of this study was to sequence the whole genome of AHPND positive V. parahaemolyticus strains isolated from shrimp (Peneaus monodon) of the south-west region of Bangladesh in 2016 and 2017 and characterize the genomic features and emergence pattern of this marine pathogen. Results Two targeted AHPND positive V. parahaemolyticus strains were confirmed using PCR with 16S rRNA, ldh, AP3 and AP4 primers. The assembled genomes of strain MSR16 and MSR17 were comprised of a total of 5,393,740 bp and 5,241,592 bp, respectively. From annotation, several virulence genes involved in chemotaxis and motility, EPS type II secretion system, Type III secretion system-1 (T3SS-1) and its secreted effectors, thermolabile hemolysin were found in both strains. Importantly, the ~69 kb plasmid was identified in both MSR16 and MSR17 strains containing the two toxin genes pirA and pirB. Antibiotic resistance genes were predicted against β-lactam, fluoroquinolone, tetracycline and macrolide groups in both MSR16 and MSR17 strains. Conclusions The findings of this research may facilitate the tracking of pathogenic and/or antibiotic-resistant V. parahaemolyticus isolates between production sites, and the identification of candidate strains for the production of vaccines as an aid to control of this devastating disease. Also, the emergence pattern of this pathogen can be highlighted to determine the characteristic differences of other strains found all over the world.

Published: November 2019

Abstract
Objective: Yeasts are unicellular microorganisms may cause systemic infection in immunocompromised patients. The aim of this study was to identify yeast strains isolated from clinical specimens using molecular techniques. Results: A total of 202 yeast strains isolated from 341 clinical samples between February 2017 and May 2019. All clinical isolates were identified using phenotypic and molecular tests including PCR-RFLP, duplex-PCR, multiplex-PCR, and PCR-sequencing. The most yeast fungal isolates were obtained from urine (66.8%), nail (9.4%), skin lesion (7.9%), bronchoalveolar lavage (5.9%), and blood (3.9%). One hundred and twenty-one Candida species were identified as non- albicans versus 76 Candida albicans. Trichosporon asahii, and Pichia terricola were uncommon non- Candida yeasts isolated from urine samples. For the first time, we isolated P. terricola as etiological agent of urinary tract infection in a pregnant female. Since Candida species show different levels of resistance to antifungal agents, precise identification of clinical isolates is critical for better treatment of infection.

Published: November 2019

Abstract
Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death in China. The lack of effective treatment results in a high recurrence rate in patients who undergo radical tumor resection, and the 5-year survival rate remains low. Our previous studies demonstrated that Plasmodium infection provides a potent antitumor effect by inducing innate and adaptive immunity in a murine Lewis lung carcinoma (LLC) model. Methods: A study was conducted to investigate the inhibitory effect of Plasmodium infection on hepatocellular carcinoma in mice, and chip analysis techniques were used to find possible signal regulation mechanisms. Results: we report that Plasmodium infection efficiently inhibited tumor progression and prolonged survival in tumor-bearing mice in a murine implanted hepatoma model. The inhibition of tumor progression by Plasmodium infection is related to the suppression of tumor angiogenesis within the tumor tissue and the decreased infiltration of tumor-associated macrophages (TAMs). Further study demonstrated that TAM-produced matrix metalloprotease 9 (MMP-9) contributed to tumor angiogenesis in the tumor tissue and that the reduced expression of MMP-9 in TAMs mediated by parasite infection resulted in the suppression of tumor angiogenesis. A mechanistic study revealed that the Plasmodium-derived hemozoin (HZ) that accumulated in TAMs inhibited IGF-1 signaling through the PI3-K and MAPK signaling pathways, which led to decreased expression of MMP-9 in TAMs. Conclusions: Our study suggests that this novel method of inhibiting tumor angiogenesis by Plasmodium infection is of high importance for developing new therapies for cancer patients.
