Published: September 2020

Abstract
Backgroundː During emergence from anesthesia after partial and total laryngectomy, excessive airway reflex and systemic hypertension may lead to subcutaneous emphysema, hemorrhage or pneumothorax.Methodsː American Society of Anesthesiologist physical status III and IV male adults undergoing elective laryngectomy were recruited and randomly allocated to receive either dexmedetomidine (group D) or midazolam (group M). The primary outcome was incidence and severity of cough. Pulse oximetry results (SpO2), heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were also recorded. The visual analog scale and the Ramsay sedation scale were recorded at the points of wakefulness and departure from the post-anesthesia care unit (PACU). Rescue analgesia consumption, the time of spontaneous breath recovery, duration of the PACU stay, and the incidence of adverse effects were also recorded.Resultsː The prevalence of no coughing was significantly higher in group D than in group M at the points of wakefulness and departure. HR, SBP, and DBP were significantly lower in group D compared with group M, and SpO2 was significantly higher in group D than in group M at the moment of laryngectomy. Pain scores were lower in group D than in group M. The Ramsay score at the point of wakefulness was higher in group D than in group M. There was no difference in time to spontaneous breathing recovery, duration of the PACU stay, and incidence of adverse effects.Conclusionsː Compared with midazolam, dexmedetomidine is an effective alternative to attenuate coughing and hemodynamic changes with a low incidence of adverse events during emergence from anesthesia after partial and total laryngectomy.Trial registration: NCT03918889, registered at clinicaltrials.gov, date of registration: March 28, 2019.

Abstract
Objective: Endometriosis is a common and painful condition characterized by the formation of endometrial lesions within the peritoneal cavity. Previous studies have suggested a role for hedgehog signalling in the pathogenesis of endometriosis. We investigated the role of hedgehog signalling in the establishment of endometriosis lesions using 5E1, a hedgehog ligand neutralising antibody, and a mouse model of endometriosis. To mimic the initiation of by endometriosis by retrograde menstruation, which is believed to occur in humans, donor mice underwent an artificial menstruation protocol. Fragments of menstrual endometrium were injected into the peritoneal cavity of estrogen primed recipients. Recipients received twice weekly injections of 5E1 or an isotype matched control antibody for three weeks. Lesions were collected and analysed for markers of epithelium, proliferation and apoptosis by immunofluorescence microscopy.Results: Treatment with 5E1, reduced the number of lesions found on the mesentery. No significant changes were found in the size of lesions, abundance of endometrial epithelial cells, proliferation or apoptosis.

Abstract
Background Otoscopy is an important clinical skill to master in the undergraduate medical curriculum. This study investigated the effect of a supplementary web-based learning platform in improving diagnostic ability and confidence in otoscopy among final year medical undergraduates in Universiti Kebangsaan Malaysia Medical Centre (UKMMC).MethodsA supplementary otoscopy training using a web-based learning platform was introduced to final year medical undergraduates who have completed a three-week posting in otorhinolaryngology. A total of 45 subjects who participated in the learning platform were included in this prospective interventional study. All of them answered questionnaires on level of confidence (LC) and completed online questions on diagnostic ability (DA) at three different timelines during the study: prior to intervention (T1), after intervention (T2) and 4 months following the intervention (T3).ResultsLC scores were significantly higher across the timelines measured: T1 vs T2 vs T3 respectively (p<0.05). DA scores were significantly higher across the timelines measured: T1 vs T2 vs T3 respectively (p<0.05). Both LC and DA scores showed sustained improvements at 4 months post intervention across both external auditory canal and tympanic membrane anatomical subsites. ConclusionSubjects’ level of confidence in performing otoscopy and diagnostic ability showed sustained improvements at 4 months with this intervention. We conclude that supplementary otoscopy training using a web based learning platform complements the teaching and learning of otoscopy among final year medical undergraduates.

Abstract
BackgroundTo evaluate the level and correlation of serum neuropeptide cakiNnin gene-elated peptide (CORP), somatostatin (SS) and inflammatory factors (CRP, TNF-o, MCP-1 and sICAM-1) in patients with coronary atherosclerotic heart disease (CAD) complicated with type 2 diabetes mellitus (DM), to explore the mechanism of diabetic patients prone to complicated CAD.MethodsPatients were divided into three groups according to corcmary angiography results and whether there was a history of type 2 diabetes: control group (no CAD or DM; n 58), CAD group (stable CAD without DM; n 68) and DM+CAD group (stable CAD+DM; n =66). The age, sex ratio and body mass index (BMI) of the three groups were balanced, and the indexes of serum CORP, SS and inflammatory factors (CRP, TNE-a, IL-113, MCP-1 and sICAM-1) were measured by ELASA method. The relationship between serum CORP, SS and inflammatory factors (CRP, TNE-¢,11,-1), MCP-1 and sICAM-1) were analyzed by Spearman correlation analysis, and the risk factors f CAD were analysed by binary logistic regression model.ResultsThere were significant differences between neuropeptides (CORP, SS) and inflammatory factors (CRP, TNT', IL-I, MCP-1 and sICAM-1) in the th©© groups. Compared with the control group and the CAD group, CGRP and SS were decreased (P < 0.05), and inflammatory factors were significantly increased (P < 0.05) in the DMTCAD group. CGRP and SS were negatively correlated with inflammatory factors. Logistic regression model showed that CORP, SS, 11-10 and MCP-1 were independent risk factors for CAD (P <0.05). ConclusionCompared with the control group and the CAD group, patients in the DMTCAD group had less CGRP and SS but more inflammatory factors. Moreover, the inflammabry factors were negatively correlated with neuropeptides, and neuropeptides and some inflammatory factors are independent risk factors for CAD. This suggests that the TRPV1 injury in the sensory nerve endings and the reduction of neuropeptides release in type 2 diabetic patients may increase the risk of CAD. The mechanism may include that these neuropeptides may inhibit the inflammatory response to some extend

Abstract
Background: Mother and fetal Doppler ultrasound during pregnancy is an established and safe tool for quantitative analysis of the utero-placental and the fetoplacental blood flow and seems to be affected by Ethnic hetérogenicity. Objective. To establish normative data for the resistive index of Uterine arteries, Umbilical artery and middle cerebral artery of Cameroonian pregnant women in the second half of pregnancy using multiples of the median and percentile reference range.Methods. We conducted a cross-sectional study on 93 low risk singleton gestation women aged above 18 years between 28 and 39 weeks of gestation in two hospitals in Cameroon during 7 months. We seek for resistive index (RI) of both left and right uterine arteries (LUt and RUt), Umbilical artery (UmA) and Middle cerebral artery (MCA). We also estimated the gestational age (GA), the mother age, the fetal weight (EFW) and the cerebro – placental ration (CPR).Pearson's correlation analysis of the relationship between these RI and selected maternal parameters was done. Regression modeling across gestational age was performed to obtain the reference values and normogram curve with values ranged at 5 and 95th percentiles. P < 0.05 was considered statistically significant.Results. The mean GA and EFW was 33.5 +/- 2.92 weeks (médian of 34) and 2337.5 +/- 734 g respectively. The means RI value of target vessels were 0.55 +/- 0.077; 0.76 +/- 0.071 ; 0.48 +/- 0.077 and 0.46 +/-0.087 for UmA, McA, RUt and LUt with extremes values of des 0.38 to 0.77 ; 0.49 to 0.87; 0.30 to 0.70 and 0.29 to 0.69 respectively. Only UmA RI and CPR values had shown correlations with GA (r= - 0.338, p≤0.01 and r=0.314; p≤0.001) and EFW (r=-0.445, p≤0.001 and r=0.234; p = 0.02). No difference between LUt and RUt RI values was found. The nomogram curve for UmA, McA, RUt and LUt value revealed a general low RI values of in our sample.Conclusions. Fetal Doppler should carefully interpreted according to general low RI values during low risk singleton pregnancy shown by this study. The generated 5and 95th percentiles RI values curves for each target vessel could be useful in that way.Trial registration:N°431/UY1/FMSB/VDRC/CSD du 24 mai 2017 by the Institutional Review Board at the faculty of Medicine and Biomedical Sciences of University of Yaoundé 1.

Abstract

Background
A previous 2-year cohort study has shown that isolated high home systolic blood pressure (IH-HSBP) may increase the risk of diabetic nephropathy. However, this association has not been previously assessed over medium to long term.
Methods
This prospective 5-year cohort study of 424 patients with normoalbuminuria investigated the effect of IH-HSBP on the risk of diabetic nephropathy in patients with type 2 diabetes mellitus. Diabetic nephropathy was defined as advancement from normoalbuminuira to micro- or macroalbuminuria.
Results
Among 424 patients, 75 developed diabetic nephropathy during the study period. Adjusted odds ratio of developing diabetic nephropathy because of IH-HSBP was 2.39 (95% confidence interval 1.15–4.96, p = 0.02). Sex; body mass index; duration of diabetes mellitus; and levels of hemoglobin A1c, total cholesterol, creatinine; and use of renin-angiotensin-aldosterone system inhibitors were included in the model as covariates.
Conclusions
IH-HSBP was associated with an increased risk of diabetic nephropathy among type 2 diabetes mellitus patients with normoalbuminuria over medium to long term. These findings suggest that IH-HSBP might be a useful marker in disease prognostication.

Published: September 2020

Abstract
Background: Several of the molecular constituent factors in the pathophysiology of Multiple Sclerosis (MS). Neuropilins are transmembrane glycoproteins which have to be receptors for the vascular endothelial growth factor (VEGF) family of angiogenesis factors. The role of angiogenesis factors of Neuropilin-1 and 2 in the pathology of MS is unknown. Methods: We aimed to investigate levels of serum Neuropilin-1 and 2 in Relapsing-Remitting Multiple Sclerosis (RRMS), and Clinically Isolated Syndrome Patients (CIS) and to investigate a correlation with, age, sex, Expanded Disability Status Scale (EDSS) and relationship with immunomodulatory therapy. Serum Neuropilin-1 and 2 concentrations of 46 RRMS patients and 28 CIS patients and 45 healthy control group were analyzed. Clinical status was evaulated using the Expanded Disability Status Scale (EDSS). Results: Neuropilin-1 and 2 concentrations matched for immumodulatuar treatment, age and sex at a group level.Neuropilin levels were found to be significantly higher in the CIS and RRMS patient’s groups compared with the control group (p˂0,001). No statistically significant difference was found between groups; age, immunmodulatuar treatment, EDSS and gender. Conclusions: Neuropilin-1 and 2 levels have been shown to increase in RRMS and CIS patients. Neuropilins, one of the factors of angiogenesis, may be effective in pathophysiology since the first period of the disease.

Abstract
Background: The application of minimally invasive surgery in patients with colorectal cancer (CRC) and a history of previous abdominal surgery (PAS) remains controversial. This retrospective study with propensity score matching (PSM) investigated the impact of PAS on robotic-assisted rectal surgery outcomes in patients with rectal cancer undergoing preoperative concurrent chemoradiotherapy (CCRT).Methods: In total, 203 patients with rectal cancer who underwent preoperative CCRT and robotic-assisted rectal surgery between May 2013 and December 2019 were enrolled. Patients were categorized into PAS and non-PAS groups based on the PAS history. The PSM caliper matching method with 1-to-3 match was used to match PAS patients with non-PAS.Results: Of the 203 enrolled patients, 35 were PAS patients 168 were non-PAS patients. After PSM, 32 PAS patients and 96 non-PAS patients were included for analysis. No significant between-group differences were noted in the perioperative outcomes, including median console time [165 min (PAS) vs 175 min (noon-PAS), P = 0.4542)] and median operation time [275 min (PAS) vs 290 min (non-PAS), P = 0.5943)] after PSM. Postoperative recovery and overall complication rates were also similar (all P > 0.05). Moreover, the between-group differences in pathological or short-term oncological outcomes were also nonsignificant (all P > 0.05). No 30-day postoperative deaths were observed in either group.Conclusion: The current results indicate that robotic-assisted surgery is safe and feasible for PAS patients with rectal cancer undergoing preoperative CCRT. However, future prospective randomized clinical trials are required to verify these findings.

Abstract
Background
To determine whether long-term intensity of glycemic exposure (IGE) during young adulthood is associated with multiple target organs function at midlife independent of single fasting glucose (FG) measurement.
Methods
We included 2,859 participants, aged 18–30 years at Y0, in the Coronary Artery Risk Development in Young Adults (CARDIA) Study. IGE was calculated as the sum of (average FG of two consecutive examinations × years between the examinations) over 25 years. Target organs function was indicated by cardiac structure, left ventricular (LV) systolic function, LV diastolic function, coronary artery calcium (CAC) and urine albumin-to-creatinine ratio (UACR) at Y25. We evaluated the associations between IGE with target organs function using linear regression models and estimated the associations between IGE with numbers of organs involved (0, 1, or ≥ 2 organs) using multinomial logistic regression models.
Results
A 1-SD increment of IGE was significantly associated with worse target organs function after multivariable adjustment: left ventricular mass (β [SE], 5.468 [1.175]); global longitudinal strain (β [SE], 0.161 [0.071]); E/e’ ratio (β[SE], 0.192 [0.071]); CAC score (β [SE], 27.948 [6.116]) and log UACR (β [SE], 0.076 [0.010]). Besides, IGE was independently associated with having ≥ 2 organs involved in both overall population (OR [95% CI], 1.48 [1.23, 1.41], p < 0.001) and subgroups stratified by diabetes at Y25.
Conclusions
Higher intensity of glycemic exposure during young adulthood was independently associated with subclinical alterations of target organs function at midlife. Our findings highlight the importance of early screening and management of IGE in youth.

Abstract
Background: Coronavirus disease 2019 (COVID-19) is a disease that causes fatal disorders including severe pneumonia. Our study aimed to utilize bioinformatics method to analyze the expression profiling by high throughput sequencing in human bronchial organoids/primary human airway epithelial infected with SARS-CoV-2 to identify the potentially crucial genes and pathways associated with COVID-19.Methods: We analyzed microarray datasets GSE153970 and GSE150819 derived from the GEO database. Firstly, the Differentially expressed genes （DEGs） in human bronchial organoids/primary human airway epithelial infected with SARS-CoV-2. Next, the DEGs were used for GO and KEGG pathway enrichment analysis. Then, the PPI network was constructed and Cytoscape was used to find the key genes.Results: Gene expression profiles of GSE153970 and GSE150819, in all 12 samples were analyzed. A total of 145 DEGs and 5 hub genes were identified in SARS-CoV-2. Meanwhile, we found that the 145 genes are associated with immune responses and the top 5 hub genes including CXCL8, CXCL1, CXCL2, CCL20, and CSF2 were mainly related to leukocyte migration, endoplasmic reticulum lumen, receptor ligand activity. In addition, the results also showed that the hub genes were associated with Cytokine−cytokine receptor interaction, IL−17 signaling pathway, and Rheumatoid arthritis in SARS-CoV-2 infection.Conclusion: The five crucial genes consisting of CXCL8, CXCL1, CXCL2, CCL20, and CSF2 were considered as hub genes of SARS-CoV-2, which may be used as diagnostic biomarkers or molecular targets for the treatment of SARS-CoV-2. It is evidenced that bioinformatics analyses in SARS-CoV-2 can be useful for understanding the underlying molecular mechanism and exploring effective therapeutic targets.

Abstract
Background: Abnormal eye movements are common in spinocerebellar ataxias Type 3 (SCA3). We conducted the research to explore the frequency of abnormal eye movements in Chinese patients with SCA3, to compare the demographic and clinical characteristics between SCA3 patients with and without each type of abnormal eye movement, and to explore the correlation between abnormal eye movements and the severity of ataxia.Methods: Seventy-four patients with SCA3 were enrolled in this cross-sectional study. Six types of abnormal eye movements including impaired smooth pursuit, increased square-wave jerks (SWJ), gaze-evoked nystagmus (GEN), slowing of saccades, saccadic hypo/hypermetria and supranuclear gaze palsy were evaluated by experienced neurologists. The severity of ataxia was evaluated by Scale for the Assessment and Rating of Ataxia (SARA). Results: The prevalence of impaired smooth pursuit, increased SWJ, GEN, slowing of saccades, saccadic hypo/hypermetria and supranuclear gaze palsy in Chinese SCA3 patients was 28.4%, 13.5%, 78.4%, 41.9%, 23.0%, and 5.4%, respectively. SCA3 patients with GEN had higher scores of International Cooperative Ataxia Rating Scale (ICARS-IV) and total ICARS, and longer length of CAG repeat than patients without GEN. SCA3 patients with slowing of saccades had a longer disease duration, higher scores of ICARS-I, ICARS-II, total ICARS and SARA than patients without slowing of saccades. SCA3 patients with saccadic hypo/hypermetria had higher scores of ICARS-III, ICARS-IV, and SARA than patients without saccadic hypo/hypermetria. The demographic and clinical characteristics did not differ significantly between SCA3 patients with and without impaired smooth pursuit, increased SWJ, or supranuclear gaze palsy. Multivariate linear regression showed that the number of abnormal eye movements (0-6), disease duration, Hamilton Depression Rating Scale-24 (HDRS-24) score, and CAG repeat length were positively correlated with SARA score, whereas Montreal Cognitive Assessment (MoCA) score was negatively correlated with SARA score in SCA3. Conclusions: An increased number of abnormal eye movement types correlated with the severity of ataxia in SCA3.
