Abstract
Background The present study focuses on diversity and biological activities of the endophytic fungal community from Distylium chinense , a rare waterlogging tolerant plant endemic to the Three Gorges Reservoir. This study has been explored the characteristics of endophytic fungi in waterlogged environment including both aquatic and terrestrial fungi, and they may produce new metabolites under complex and extreme conditions, which may possess bioactive property. Therefore, the antioxidant, antimicrobial and anticancer activities of all endophytes isolated from this study have been investigated. Moreover, the active metabolites of the most broad-spectrum bioactive strain have also been studied.Results A total of 154 fungal endophytes were isolated from roots and stems. They were categorized into 30 morphotypes based on cultural characteristics and were affiliated with 27 different taxa. Among these, the most abundant fungal orders included Diaporthales (34.4%) and Botryosphaeriales (30.5%), which were predominantly represented by the species Phomopsis sp. (24.7%) and Neofusicoccum parvum (23.4%). Fermentation extracts were evaluated, screening for antioxidant, antimicrobial and anticancer activities. Among the 154 isolates tested, 99 (64.3%) displayed significant antioxidant activity, 153 (99.4%) exhibited inclusive antimicrobial activity against at least one tested microorganism and 27 (17.5%) showed exclusive anticancer activity against one or more cancer cell lines. Specifically, the crude extract of Irpex lacteus DR10-1 exhibited note-worthy bioactivities. Further chemical investigation on DR10-1 strain resulted in the isolation and identification of two known bioactive metabolites, indole-3-carboxylic acid ( 1 ) and indole-3-carboxaldehyde ( 2 ), indicating their potential roles in plant growth promotion and human medicinal value.Conclusions These results indicated that diverse endophytic fungal population inhabits D. chinense . The isolated endophyte DR10-1 ( Irpex lacteus ) has the potential to be a source of novel antioxidant/antimicrobial/anticancer compounds. The findings of the present study not only provide a sustainable resource for the utilization of endophytic fungi in D. chinense but also provides an important basis for further understanding of fungal communities in medicinal plants.

Abstract
Background The World Health Organization (WHO) End Tuberculosis Strategy calls for a 90% reduction in tuberculosis (TB) deaths and an 80% reduction in the incidence rate between 2015 and 2035. The 2018 WHO guidelines recognize the need for high-burden countries to implement outreach and treatment for the most vulnerable patients with latent TB infection (LTBI) in addition to treating patients with the active disease. The Democratic Republic of Congo (DR Congo) is among the countries bearing the highest burden of TB. However, additional data on LTBI is required for effective policy and strategy against the disease. Accordingly, the aim of this study is to estimate the prevalence of LTBI in HIV-infected adults in Kinshasa, DR Congo. Methods Over two hundred HIV-infected adult residents of Kinshasa were screened using both TUBERTEST®, which is a tuberculin skin test (TST), and QuantiFERON-TB Gold Plus® (QFT-Plus), which is an interferon gamma release assay. LTBI was screened using TST, QFT-Plus, and a combination of the two tests. The agreement between TST and QFT-Plus was calculated using Cohen’s Kappa coefficient. Results A total of 248 HIV-infected persons were enrolled in the study. Seventy-six patients (30.7% IC 95%: 25.2-36.7) had a positive TST result. Sixty-four (25.8% IC 95%: 20.7-31.6) had a positive QFT-Plus test result. The Kappa coefficient between TST and QFT-Plus was 0.225. Conclusions The prevalence of LTBI among HIV positive adults in Kinshasa was high considering either the positive TST or the positive QFT-Plus. However, the two tests had poor agreement.

Abstract
Bankground: The objective of this paper was to describe the first symptoms associated with systemic lupus erythematosus (SLE), including clinical manifestations, laboratory findings, prognoses, differences between men and women at the time of first diagnosis of SLE. Methods : We enrolled 223 patients with initial diagnosis of SLE. Their initial symptoms, demographic, clinical and laboratory data，prognoses and causes of death were analyzed retrospectively. Clinical manifestations and laboratory profiles were compared between male and female patients. Results: Compared with female patients, male patients had an earlier age of onset, a higher incidence of neuropsychiatric involvements, a lower incidence of leukocytopenia , and a higher score of SLE Disease Activity Index (SLEDAI）at diagnosis. Fever and malar rash were most frequent presentations at onset of SLE. The most common clinical manifestation at first diagnosis was fever, followed by arthralgia, malar rash, Raynaud ’ s phenomenon, arthritis. The liver function abnormalities included increased ALT,AST,ALP and γ-GGT.ANA were found in 100% of patients, followed by anti-dsDNA(LIA) in 72.1%, anti-Ro60 in 67.8%, anti-Ro52 in 62.3%, anti-nucleosomes in 55.7%. Conclusions: We identified clinical and serological manifestations of Chinese SLE patients at first diagnosis. Male patients showed a distinctive manifestation including younger age of onset，a higher incidence of CNS manifestations, a higher score of SLEDAI compared to females.

Abstract
Background: There is a significant lack of research in the Nepalese study population on adherence in patients with schizophrenia. This cross-sectional, non-interventional study aims to re-examine the recognised correlation between insight and adherence in this population, whilst exploring the association between patient demographics and adherence to help bring understanding to how familial and environmental factors may impact adherence. Methods: Patients were recruited upon attendance to outpatient’s appointments and admission to the psychiatry department of Manipal Teaching Hospital. A self-report questionnaire was used to collect data on patient demographics, including age, ethnicity, religion, employment status, current living arrangements and education level; the Birchwood Insight Scale (BIS); and the Drug Attitude Inventory (DAI-10) score. Descriptive statistics on the demographics, BIS and DAI-10 were collated using SPSS. An analysis of variance of DAI-10 scores according to participant demographics was performed using a one-way ANOVA analysis. Correlation between the BIS and BIS subscales and the DAI-10 was tested using Pearson’s 2-tailed analysis at 0.01 significance level.Results: 19 participants consented to participate in this study with 100% data obtained. 57.9% unemployed, 63.2% living with parents and 47.4% had only a basic education. 36.8% of participants had poor insight; 84.2% of participants had poor insight into their symptoms; 78.9% of participants had poor insight into their illness and 36.8% had poor insight into their need for treatment. 52.7% of participants were poor adherers. No significant differences in DAI-10 scores were found between demographic groups. A positive correlation was found between the total BIS score and DAI-10 score (Pearson correlation coefficient of 0.585; P value = 0.009). Furthermore, the awareness of need for treatment subscale score and the DAI-10 score found a correlation coefficient of 0.609 (P value = 0.006). Conclusions: In conclusion, this study found prevalent non-adherence to medication and demonstrated that insight correlates with adherence. Although study findings did not suggest that patient demographics were associated with non-adherence, it is important to consider the possibility that these high rates of non-adherence have other contributing factors; overcoming rural health inequality, cultural beliefs regarding psychiatric illness and unaffordability remain the great challenges for the Nepalese population.

Abstract
Background Suicidal ideation and attempt are highly prevalent among medical students compared to the general population and negatively impacts the quality of life, physical, and mental well being of students. However, research into suicidal ideation and attempt among medical students in low and middle-income countries are limited. Therefore, this study aimed to explore the suicide ideation and attempt and associated factors among medical students in Ethiopia.Methods An institution based cross-sectional study was conducted from March to June 2019 at the University of Gondar among medical students. A simple random sampling technique used to get study units by their identification card. Suicide ideation and attempt were assessed by using World Health Organization Composite International Diagnostic Interview (CIDI) to assess suicide ideation and attempt. Data were collected using self-administered questionnaires. Binary logistic regression analysis was used to identify associated factors between suicidal ideation and attempt with the explanatory variables at p-value <0.05 was considered statistically significant.Results The prevalence of suicidal ideation and attempt among study participants was found to be 14% and 7.4% with 95% CI (10.9, 18.1) and (5.1, 10.2), respectively. In multivariate logistic regression; female sex (AOR: 5.21, 95% CI: 2.42, 11.20), depression (AOR: 10.12, 95% CI; 4.80, 21.52), current khat chewing (AOR: 4.46, 95% CI; 132, 15.02), and poor social support (AOR: 4.46, 95% CI: 1.43, 13.87) were factors significantly associated with suicidal ideation. Being female (AOR: 8.08, 95% CI: 3.04, 21.39), depression (AOR: 10.66, 95% CI; 4.01, 28.01 ) and history of mental illness (AOR: 5.53, 95% CI; 1.20, 25.50) were factors significantly associated with suicidal attempt.Conclusion In the current study, the prevalence of suicidal ideation among medical students was low compared to other studies, but the suicidal attempt was high. The University of Gondar better to instate a screening program for every medical student for early diagnosis and intervention of suicide ideation and attempt.

Abstract
Background It has been shown that iron deficiency anemia (IDA) is associated with psychosocial consequences and psychiatric morbidity. However, the association between adults with IDA and psychiatric disorders has not been clarified. The purpose of this study is to investigate the psychiatric disorders morbidity of IDA in comparison with non-IDA group and to examine the risk of psychiatric disorders in IDA patients treated with iron supplementary.Methods All study subjects aged ≥ 20 years with newly diagnosed IDA in the Taiwan National Health Insurance Database during 2000-2012 were enrolled. We matched IDA and non-IDA subjects according to age and gender in a 1:2 ratio. Our primary outcome was diagnosis of psychiatric disorders and the patients were monitored until the end of 2013. The Cox proportional hazards regression model was used to evaluate the risk of psychiatric disorders events to occur in IDA.Results The adjusted hazard ratios (aHR) of psychiatric disorders was 1.49 (95% CI = 1.43 – 1.56) in the IDA group compared with the non-IDA group. Among the different type of psychiatric disorders occurrence, the IDA group was associated with significantly higher incidence and risks of dementia, anxiety disorders, depression, sleep disorders and psychotic disorders (p < 0.05). Furthermore, iron supplementation use to IDA subjects was associated with significantly lower risk of psychiatric disorders compared with IDA patients without iron supplementation.Conclusions Our study indicates that IDA had an increased risk of psychiatric disorders, regardless of other confounders. Moreover, in IDA patients, iron supplementation use could reduce the risk of psychiatric disorders, especially sleep disorders.

Abstract
Background: Good sibling relationships in adulthood are known to be a protective factor for mental health. The present study examined and compared the relationships of siblings with either a healthy brother or sister or one experiencing schizophrenia. Methods: In the first phase, we ran a statistical comparison of the two sibling groups on the quality of their sibling relationships, emotional distress, and self-esteem. In the second phase, we looked at whether the quality of the sibling relationship modifies the impact of having a brother or sister with SZ on emotional distress and self-esteem. Results: Results showed that sibling relationships in schizophrenia are less warm and are characterized by heightened rivalry and conflict. In addition, analysis revealed a mediating effect of sibling relationship on the emotional distress of siblings with a brother/sister diagnosed with schizophrenia. Conclusion: More needs to be done to enhance the mental health of adults who have a brother or sister with schizophrenia, notably via their sibling relationships.

Abstract
Objective Delirium is a serious and distressing neurocognitive disorder of physiological aetiology that is common in advanced cancer. Understanding of delirium pathophysiology is largely hypothetical, with some evidence for involvement of inflammatory systems, neurotransmitter alterations and glucose metabolism. To date, there has been limited empirical consideration of the distinction between delirium pathophysiology and that of the underlying disease, for example, cancer where these mechanisms are also common in advanced cancer syndromes such as pain and fatigue. This systematic review explores biomarker overlap in delirium, specific advanced cancer-related syndromes and prediction of cancer prognosis. Methods A systematic literature search was conducted, using MEDLINE, PubMed, Embase, CINAHL, CENTRAL and Web of Science, to identify body fluid biomarkers in delirium, cancer prognosis and advanced cancer-related syndromes of interest. Studies were excluded if they reported delirium tremens only; did not measure delirium using a validated tool; the sample had less than 75% of participants with advanced cancer; measured tissue, genetic or animal biomarkers, or were conducted post-mortem. Articles were screened for inclusion independently by two authors, and data extraction and an in-depth quality assessment conducted by one author, and checked by two others. Results The 151 included studies were conducted in diverse settings in 32 countries between 1985 and 2017, involving 28130 participants with a mean age of 69.3 years. Seventy-one studies investigated delirium biomarkers, and 80 studies investigated biomarkers of an advanced cancer-related syndrome or cancer prognosis. Overall, 41 biomarkers were studied in relation to both delirium and either an advanced cancer-related syndrome or prognosis; and of these, 24 biomarkers were positively associated with either delirium or advanced cancer syndromes/prognosis in at least one study. The quality assessment showed large inconsistency in reporting. Conclusion There is considerable overlap in the biomarkers in delirium and advanced cancer-related syndromes. Improving the design of delirium biomarker studies and considering appropriate comparator/controls will help to better understanding the discrete pathophysiology of delirium in the context of co-existing illness.

Abstract
Background: To explore the profile and clinical significance of proinflammatory cytokines in serum and bronchoalveolar lavage fluid (BALF) of children with Mycoplasma pneumoniae pneumonia(MPP) and to elucidate the etiology and pathogenesis of severe MPP (SMPP). Methods: A cohort of 108 children with MPP was divided into SMPP (n=56) and non-severe MPP (NSMPP) (n=52). A total of 40 cases of hospitalized children, who underwent elective surgery, were selected as control group. The levels of proinflammatory cytokines in the serum and BALF were measured by ELISA(Enzyme-linked immunosorbent assay). Results: Compared to the control group, the MPP children showed that the levels of peripheral blood (PB) TNF-a, IFN-g, GM-CSF, IL-17, IL-18, IL-36a, sB7-H1, and sB7-H3 were much higher at the acute phase (P<0.05). Also, they were significantly higher in the SMPP group than that in the NSMPP group (P<0.05). Furthermore, in the SMPP group, the levels of TNF-a, IFN-g, GM-CSF, IL-1b, IL-2, IL-8, IL-36, MPO, MMP-9, NE, sB7-H3 in BALF were significantly higher at acute phase as compared to the control group (P<0.05). sB7-H3 was positively correlated with major proinflammatory cytokines in both PB and BALF specimens. The level of sB7-H3 in PB was >8000 pg/mL was an independent risk factor for SMPP. Conclusions: Excessive inflammation plays a critical role in the occurrence and development of MPP, especially SMPP, and sB7-H3 is an independent risk factor of SMPP.

Abstract
Background: Group B streptococcus (GBS), a gram-positive coccus that occasionally causes neonatal sepsis or invasive infection in the elderly, has been considered a rare cause of endogenous bacterial endophthalmitis (EBE). However, the number of invasive GBS infections is increasing, particularly in elderly patients with underlying conditions such as diabetes mellitus (DM), cardiovascular disease and cancer. We report 6 cases of EBE caused by GBS and review the literature. Methods: Retrospective case series and literature review Results: In the current case series, 6 eyes of 6 patients developed EBE caused by GBS. The average age was 73.5 years. The focus of infection included the urinary tract, cellulitis, arthritis, peritonitis, catheter-associated infection and endocarditis. Four patients had DM. While all 6 strains were sensitive to β-lactams (penicillins and cephems), 4 strains were resistant to levofloxacin (no data for 1 isolate). Each case was treated with the systemic antibiotic to which the individual strain was sensitive. All cases showed poor visual acuity at presentation (decimal visual acuity: less than 0.03). Vitrectomy with intravitreal antibiotics injection was performed in 4 cases. Visual acuity recovered in 4 cases and did not recover in 2 cases, even after vitrectomy. The literature review of 53 eyes of 41 patients revealed that 60% of eyes finally lost all vision, and death occurred in 2 cases. Initial visual acuity of less than counting fingers was associated with a final outcome of lost vision. Of 41 patients, 13 (32%) had DM as an underlying medical condition. The most common extra-ocular infection site was endocarditis (37%). Conclusions: DM is common in patients with EBE caused by GBS. While the 4 cases in the current report had a relatively good visual acuity outcome, despite poor initial visual acuity, the literature review indicated that EBE caused by GBS is generally a severe condition with a poor prognosis. The current study also indicates the importance of considering the possibility of endocarditis on encountering EBE caused by GBS.

Abstract
Background/Aims To examine the effect of pharmacologic dilation on biometric parameters measured by the Lenstar LS 900, and whether these changes affect the power of the calculated intraocular lens (IOL) using multivariable formulas in an undilated versus pharmacologically dilated state. Methods Prospective study of 98 phakic eyes from 53 patients. Axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), and keratometry (K) readings were measured. The first set of measurements was taken prior to dilation. After dilation (pupil diameter ≥6.0mm), a second set of measurements was taken. The Barrett, Olsen, Hill-RBF, Haigis, SRK/T, and Holladay I formulas were used to calculate IOL power before and after dilation. Two calculation methods were used: Method A used a commonly available IOL targeted to achieve the lowest myopic spheroequivalent residual refraction (LMP); Method B calculated ideal IOL power for emmetropia (IPE). Results Statistically significant increases were seen in CCT (p<0.01), ACD (p<0.01), and AL (p<0.01) whereas a statistically significant decrease was seen in LT (p<0.01) post dilation. Using Method A, the percentage of eyes which would have received an IOL with 0.5 D or 1.0 D of higher power, if post-dilation measurements were used, were 25.5%, 30.6%, 20.4% and 23.5% for Barrett, Olsen, Hill-RBF and Haigis, respectively. Using Method B, only Haigis and Olsen had a statistically significant increase in ideal IOL power. Conclusions Pharmacologic dilation can be associated with an increase in non-custom IOL dioptric power when using multivariable formulas, which may lead to a myopic surprise.
