Background and aim: To analyze the prevalence of ophthalmic manifestations in patients with celiac disease, Crohn’s disease and ulcerative colitis in Munich/Germany. Methods: A total of 272,873 patients of Ludwig Maximilians Universitat Ophthalmological Hospital with eye disease were evaluated between 2003 and 2019. The International Classification of Diseases, 10th revision (ICD-10) of celiac disease Crohn’s disease, ulcerative colitis, and all medical records which had the diagnosis of these diseases were analyzed. Results: A total of 272,873 patients were analyzed, with a mean age of 53 years, with approximately 48% female patients, and 51% male patients. We selected 72 patients with celiac disease (68% women and 32% men), with a minimum age of 8 years, maximum of 103 years, and an average of 52 years. The most common diagnoses were dry eye (32%) and cataract (12%). The mean intraocular pressure of patients with celiac disease was 15 mmHg. During the same study period, 103 patients with Crohn’s disease were analyzed, with an average intraocular pressure of 14 mmHg.The minimum age of the patients was 12 years and a maximum of 93 years with an average age of 55 years, with 57% of females and 43% of males. The most common diagnoses were cataract (22%) and dry eye (19%). During the same study period, 99 patients with ulcerative colitis were analyzed, with an average intraocular pressure of 14 mmHg.The minimum age of the patients was 6 years and a maximum of 96 years, with an average age of 61 years, with 36% of females and 64% of males. The most common diagnoses were cataract (29.2%) and dry eye (12%). Conclusions: The main ophthalmological manifestations of patients requiring eye follow-up were dry eye and cataract for all the diseases analyzed, which can be considered as coincident complications. None of the three diseases had increased intraocular pressure. Thus, celiac disease presented a profile of ophthalmological manifestation similar to the other intestinal inflammatory diseases studied.

Purpose: To assess the association between carbohydrates (CH) intake and glaucoma incidence. Methods: 18,247 volunteer participants (183,067 person-years at risk) with 10-year of median follow-up were included in this prospective dynamic cohort. Baseline total CH intake (g/d) was categorised in quartiles and classified in nine different CH food sources. Self-reported diagnosis of glaucoma was collected at baseline and on biennial follow-up questionnaires. CH intake and glaucoma diagnosis were validated in a subsample of participants. We studied potential confounders and effect modificators, including diabetes. The relationship between CH intake and glaucoma incidence was analysed using multivariable Cox proportional hazards ratio (HR) models to adjust for potential confounding factors. Results: During 10 years of median follow-up, a total of 242 new cases of glaucoma were identified. Participants in the highest quartile of baseline CH intake had a significantly higher risk of glaucoma as compared to participants in the lowest quartile [HR 1.50 (95% Confidence interval (CI): 1.01–2.25), p for trend = 0.042]. None of the nine CH food groups was individually related to glaucoma. In stratified analyses, after excluding all cases of diabetes, the HR comparing extreme quartiles of CH intake was 1.77 (95% CI: 1.15–2.74). Conclusions: Our results suggest that a higher intake of total carbohydrates is associated with a higher risk of incident glaucoma. The total amount of CH, rather than the specific food sources of CH, seems to play a major role, and this association does not seem to be confounded or modified by diabetic status.

Published: April 2021

Objective: This present study aims to investigate the potential prognostic values of dynactin genes ( DCTN) for predicting the overall survival (OS) in low-grade glioma (LGG) patients. Methods: The DCTN mRNA expression data were downloaded from The Cancer Genome Atlas database containing 518 patients with LGG. The Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses for DCTN genes were performed by using Database for Annotation, Visualization, and Integrated Discovery platform, and their enrichment results were verified by using the Biological Networks Gene Ontology tool. Next, the correlations between DCTN genes and LGG were identified by Pearson correlation coefficient analysis. The OS was estimated by Kaplan-Meier survival analysis. The cBio Cancer Genomics Portal was used to analyze the mutations of DCTN genes and their effects on the prognosis of LGG. The correlation between the abundance of immune infiltration and tumor purity of DCTN genes were predicted by The Tumor Immune Estimation Resource. Results: Our research showed that the mRNA expression of DCTN4 in tumor tissues was much higher ( P < 0.01) than that in normal tissues. Meanwhile, there was a certain correlation between the DCTN genes. Survival analysis showed that the high expression of DCTN1, DCTN3, DCTN4, DCTN6, and their co-expression were significantly correlated with favorable OS in LGG patients ( P < 0.05). In DCTN2, a high mutation rate was observed. Further research showed that the genetic alteration in DCTN genes was related to a poor OS and progression-free survival of LGG patients. The expression of DCTN genes had a certain correlation with immune infiltrating cells. Conclusion: Our study showed that the high expressions of DCTN1, DCTN3, DCTN4, and DCTN6 were associated with a favorable OS of LGG patients, indicating that these DCTN genes are potential biomarkers for evaluating the prognosis of LGG patients.

Authors: Bekele Firomsa , Hajure Mohammedamin 
Published: April 2021

Introduction: The mental health of the health care professionals is more likely to be affected by the coronavirus disease-19 compared to the general population. Accordingly, the current study aimed to summarize the magnitudes and determinants of the psychological impact of coronavirus among health care professionals. Methods: The studies from Medline via PubMed, Science Direct, and Google Scholar were searched from 5 September to 19 October 2020. The review was conducted as per PRISMA-2009 (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Result: Initially, 6316 articles were searched from three databases (PubMed, Science Direct, and Google Scholar). Finally, 20 articles were filtered to be included in our review. Among different types of psychological impact, stress was reported that lies within the range from 5.2% to 100%, anxiety was reported from 11.1% to 100%, depression was from 10.6% to 58%, and insomnia was from 28.75% to 34%. Several factors were related to the negative psychological state of health care workers due to coronavirus disease-19 like educational level, occupation, gender, age, working environment, work experience, legal status, ethnicity, psychological comorbidity, social support, personal/family exposure, and feeling of health care providers. Conclusion: The most common psychological impacts among health care workers were anxiety and stress. Besides different sociodemographic factors that determine the psychological impacts, front-line health care workers and participants having psychological comorbidity have a high risk of negative psychological state impacts as compared to their counterparts. Therefore, special attention should tend to health care workers directly involved in the prevention and management of coronavirus disease-19 and having a different risk of mental health condition.

Study Design: Retrospective pooled analysis of individual patient data. Objectives: Spinal chondroblastoma (CB) is a very rare pathology and its clinicopathological and prognostic features remain unclear. Here, we sought to characterize the clinicopathological data of a large spinal CB cohort and determine factors affecting the local recurrence-free survival (LRFS) and overall survival (OS) of patients. Methods: Electronic searches using Medline, Embase, Google Scholar and Wanfang databases were performed to identify eligible studies per predefined criteria. A retrospective review was also conducted to include additional patients at our center. Results: Twenty-seven studies from the literature and 8 patients from our local institute were identified, yielding a total of 61 patients for analysis. Overall, there were no differences in clinicopathological characteristics between the local and literature cohorts, except for absence or presence of spinal canal invasion by tumor on imagings and chicken-wire calcification in tumor tissues. Univariate Kaplan-Meier analysis revealed that previous treatment, preoperative or postoperative neurological deficits, type of tumor resection, secondary aneurysmal bone cyst (ABC), chicken-wire calcification and radiotherapy correlated closely with LRFS, though only type of tumor resection, chicken-wire calcification and radiotherapy were predictive of outcome based on multivariate Cox analysis. Analyzing OS, we found that a history of preoperative treatment, concurrent ABC, chicken-wire calcification, type of tumor resection and adjuvant radiotherapy had a significant association with survival, whereas only type of tumor resection remained statistically significant after adjusting for other covariables. Conclusion: These data may be helpful in prognostic risk stratification and individualized therapy decision making for patients.

Abstract
Background
Knowledge about SARS-CoV-2 infection in pregnancy and newborns is scarce. The objective of this study is to analyse clinical and epidemiological characteristics of a cohort of women infected with SARS-CoV-2 during pregnancy and their newborns exposed to SARS-CoV-2 during gestation.

Methods
Multicentric observational study of Spanish hospitals from the GESNEO-COVD cohort, participants in RECLIP (Spanish Network of Paediatric Clinical Assays). Women with confirmed SARS-CoV-2 infection by PCR and/or serology during pregnancy, diagnosed and delivering during the period 15/03/2020–31/07/2020 were included. Epidemiological, clinical, and analytical data was collected.

Results
A total of 105 pregnant women with a median of 34.1 years old (IQR: 28.8–37.1) and 107 newborns were included. Globally, almost 65% of pregnant women had some COVID-19 symptoms and more than 43% were treated for SARS-COV-2. Overall, 30.8% of pregnant women had pneumonia and 5 (4.8%) women were admitted to the intensive care unit needing invasive mechanical ventilation. There was a rate of 36.2% of caesarean sections, which was associated with pneumonia during pregnancy (OR: 4.203, CI 95%: 1.473–11.995) and lower gestational age at delivery (OR: 0.724, CI 95%: 0.578–0.906). The prevalence of preterm birth was 20.6% and prematurity was associated with pneumonia during gestation (OR: 6.970, CI95%: 2.340–22.750) and having a positive SARS-CoV-2 PCR at delivery (OR: 6.520, CI95%: 1.840–31.790). All nasopharyngeal PCR in newborns were negative at birth and one positivized at 15 days of life. Two newborns died, one due to causes related to prematurity and another of unexpected sudden death during early skin-to-skin contact after delivery.

Conclusions
Although vertical transmission has not been reported in this cohort, the prognosis of newborns could be worsened by SARS-CoV-2 infection during pregnancy as COVID-19 pneumonia increased the risk of caesarean section deliveries and preterm births.

Abstract
Background
Interprofessional learning (IPL) is a key challenge in Malaysia in incorporating the current profession-specific medical education into the interprofessional learning curriculum. Safe practices would be enhanced with improved collaboration among the health professionals when they learn with, from, and about each other. The main objective of this study was to determine the significant differences in self-assessment, attitude, and perception of interprofessional learning among doctors and nurses in a teaching hospital in Klang Valley, Malaysia. The second objective was to determine if there is any significant difference in the selected demography factors, mean and total scores between doctors and nurses in self-assessment, attitude, and perceptions of IPL aspects.

Methods
A total of doctors (39) and nurses (37) were recruited for an interventional study on the interprofessional learning approach on hospital acquired infection control. The participants responded to the University of West England Interprofessional (UWEIP) questionnaire at baseline consisting of four dimensions in IPL aspects; Self-assessment on communication and teamwork skills (CTW), interprofessional learning (IPL), interprofessional interaction (IPI), and interprofessional relationship (IPR). The Cronbach alpha value for the total questionnaire was established at 0.79.

Results
The majority of doctors scored positive in CTW, IPL, IPR, and neutral in IPI. Nurses’ also recorded the highest positive scores in CTW, IPL, and IPR, and neutral in IPI. Negative scores were found in CTW and IPI. A significant difference was revealed between doctors and nurses in IPL attitude; p = 0.024 and there was no significant difference in other dimensions (p > .05). Results also found a significant difference between participants’ and non-participants of IPL training sessions; p = 0.009.

Conclusions
This study revealed the infusion of interprofessional learning training among the health professionals displayed better self-assessments, attitudes, and perceptions towards collaborative practices.

Abstract
Background
The complex interrelationships between professional identity, job satisfaction, burnout, and turnover intention among general practitioners (GPs) are insufficiently understood in China. This study aimed to investigate the interrelationships between professional identity, job satisfaction, burnout, and turnover intention in China, and to examine whether job satisfaction and burnout played mediating roles between professional identity and turnover intention.

Methods
A cross-sectional survey was conducted between October, 2017 and February, 2018 in China. The participants were selected using a multistage stratified random sampling method. Data were collected with a self-administered questionnaire from 3236 GPs (response rate, 99.8%) working in community health institutions in China. Professional identity was measured by the 13 items scale, and job satisfaction scale with an 11-item designed by Shi et al. was employed. Burnout was measured using a 22-item Maslach Burnout Inventory-Human Services Survey, and turnover intention was measured with a 6 items scale. Descriptive statistics were calculated and groups’ differences were estimated Student’s t-test and analyses of variance. Pearson’s correlation analysis was used to assess the degree of correlation among different dimensions of professional identity, job satisfaction, burnout, and turnover intention. Structural equation modeling analysis was applied to examine the interrelationships among these study variables based on the hypothesized model.

Results
The proposed model achieved a good model fit. Job satisfaction had a direct negative effect on turnover intention (β = − 0.38, P < 0.001), burnout had a direct positive effect on turnover intention (β = 0.37, P < 0.001), and professional identity had an indirect negative effect on turnover intention through the mediating effect of job satisfaction and burnout.

Conclusions
Our study elucidated the pathways linking professional identity, job satisfaction, and burnout to turnover intention of GPs. This revealed that turnover intention was significantly affected by job satisfaction and burnout, and the effects of professional identity on turnover intention can be mediated by job satisfaction and burnout.

AbstractBackgroundInequalities in the availability of maternity health services in rural Australia have been documented, but not the impact on aeromedical retrievals. This study aims to examine the prevalence of pregnancy-related aeromedical retrievals, the most common conditions (overall and in specific age groups), and their distribution according to operation area and demographic characteristics.MethodsCross-sectional study using administrative data from the Royal Flying Doctors Service (RFDS) including all pregnant women aged 15–49 years retrieved by the RFDS between 2015 and 2019. All pregnancy-related aeromedical retrievals were classified according to the International Classification of Diseases, Tenth Revision (ICD-10, chapter XV). The distribution of pregnancy-related conditions was presented overall and stratified by age group (i.e. < 20 years, 20–34 years and 35+ years). Retrieval and receiving sites were geographically mapped with Tableau mapping software® based on postcode numbers of origin and destination.ResultsA total of 4653 pregnancy-related retrievals were identified (mean age 27.8 ± 6.1 years), representing 3.1% of all RFDS transfers between 2015 and 18 and 3.5% in 2018–19 (p-value 0.01). The highest proportion of pregnancy-related retrievals (4.8%) occurred in Western operation. There was an apparent increase in pregnancy-related retrievals in South Australia and the Northern Territory (Central Operation) in 2018–19. Preterm labour/delivery was responsible for 36.4% of all retrievals (40.7% among women aged 15–19 years) and premature rupture of membranes for 14.9% (19.4% among women aged 35–49 years). Inter-hospital transfers represented 87.9% of all retrievals, with most patients relocated from rural and remote regions to urban hospitals; most retrievals occurred during the day, with a median distance of 300 km. Adolescents and Aboriginal and Torres Strait Islander were overrepresented in the sample (four and eight times higher than their metropolitan counterparts, respectively).ConclusionsThe proportion of pregnancy-related aeromedical retrievals varies geographically across Australia. Overall, one-third of retrievals were related to preterm/delivery complications, especially among adolescents. Most retrievals performed by the RFDS are susceptible to public health strategies aimed at improving antenatal care and preventing unintended pregnancies among adolescents and Aboriginal and Torres Strait Islander women. Greater capacity to manage pregnancy conditions in rural hospitals could reduce the requirement for aeromedical inter-hospital transfers.

AbstractBackgroundIschaemic postconditioning (IPoC) refers to brief periods of reocclusion of blood supply following an ischaemic event. This has been shown to ameliorate ischaemia reperfusion injury in different tissues, and it may represent a feasible therapeutic strategy for ischaemia reperfusion injury following strangulating small intestinal lesions in horses. The objective of this study was to assess the degree cell death, inflammation, oxidative stress, and heat shock response in an equine experimental jejunal ischaemia model with and without IPoC.MethodsIn this randomized, controlled, experimental in vivo study, 14 horses were evenly assigned to a control group and a group subjected to IPoC. Under general anaesthesia, segmental ischaemia with arterial and venous occlusion was induced in 1.5 m jejunum. Following ischaemia, the mesenteric vessels were repeatedly re-occluded in group IPoC only. Full thickness intestinal samples and blood samples were taken at the end of the pre-ischaemia period, after ischaemia, and after 120 min of reperfusion. Immunohistochemical staining or enzymatic assays were performed to determine the selected variables.ResultsThe mucosal cleaved-caspase-3 and TUNEL cell counts were significantly increased after reperfusion in the control group only. The cleaved-caspase-3 cell count was significantly lower in group IPoC after reperfusion compared to the control group. After reperfusion, the tissue myeloperoxidase activity and the calprotectin positive cell counts in the mucosa were increased in both groups, and only group IPoC showed a significant increase in the serosa. Tissue malondialdehyde and superoxide dismutase as well as blood lactate levels showed significant progression during ischaemia or reperfusion. The nuclear immunoreactivity of Heat shock protein-70 increased significantly during reperfusion. None of these variables differed between the groups. The neuronal cell counts in the myenteric plexus ganglia were not affected by the ischaemia model.ConclusionsA reduced apoptotic cell count was found in the group subjected to IPoC. None of the other tested variables were significantly affected by IPoC. Therefore, the clinical relevance and possible protective mechanism of IPoC in equine intestinal ischaemia remains unclear. Further research on the mechanism of action and its effect in clinical cases of strangulating colic is needed.
