Abstract Colonic bacterial biofilms are an emerging manifestation in colorectal cancer (CRC); they exhibit carcinogenic properties and are frequently present on right-sided cancerous lesions. Whether bacterial biofilms propose a risk factor for early carcinogenesis in humans is yet unresolved. Therefore, we studied bacterial biofilms in tandem with adenoma formation in patients with Lynch syndrome (LS). LS patients carry a pathogenic germline variant in one of the DNA mismatch repair (MMR) genes, resulting in a variable predisposition to develop colonic cancerous lesions. A total of 100 LS patients were included in our study, consisting of 23 MLH1, 24 MSH2, 36 MSH6, and 17 PMS2 MMR variants. During regular screening colonoscopies, normal-appearing forceps biopsies were taken from colon ascendens (right colon) and descendens (left colon). Biopsies were screened for bacterial biofilms using fluorescent in situ hybridization by targeting bacterial 16s rRNA. The frequency of colorectal adenomas (tubular adenomas and [tubulo]villous adenomas) before and during colonoscopy was registered. Overall, 60% of patients presented with a biofilm, of which most were right-sided (right-sided: 25%, both sides: 21%, left-sided: 14%). Interestingly, adenomas were more frequently present in patients with a right-sided biofilm (right-sided: 64%, both sides: 58%) than in patients with a left-sided biofilm (29%) or no biofilm (38%). The occurrence of bacterial biofilms was not correlated with age, BMI, or MMR-variant. Statistical analysis revealed that right-sided bacterial biofilms correlated with right-sided adenomas (Pearson: 0.272, p=0.007) and left-sided adenomas (Pearson: 0.227, p=0.026), while left-sided biofilms were not correlated with left- or right-sided adenomas (Pearson: 0.037, p=0.718 and -.127, p=.213). To model the probability of right-sided adenoma formation, we performed a binary logistic regression analysis and found that age (odds ratio: 1.065 [CI: 1.024; 1.108, p=0.002]) and right-sided biofilms (odds ratio: 3.020 [CI: 1.151; 7.926, p=0.025]) significantly contributed. Our data suggest that right-sided bacterial biofilms are a hallmark for high-risk LS patients and may play a role in early carcinogenesis. This abstract is also being presented as Poster A06.

Engineered Circular RNA Sponges Act as miRNA Inhibitors to Attenuate Pressure Overload-Induced Cardiac Hypertrophy
Authors: Annadoray Lavenniah, Tuan Danh Anh Luu, Yiqing Peter Li, Tingsen Benson Lim, Jianming Jiang, Matthew Ackers-Johnson, Roger S.-Y. Foo
Journal: Molecular Therapy (2020)

Circular RNAs (circRNAs) sequester microRNAs (miRNAs) and repress their endogenous activity. We hypothesized that artificial circRNA sponges (circmiRs) can be constructed to target miRNAs therapeutically, with a low dosage requirement and extended half-lives compared to current alternatives. This could present a new treatment approach for critical global pathologies, including cardiovascular disease. Here, we constructed a circmiR sponge to target known cardiac pro-hypertrophic miR-132 and -212. Expressed circmiRs competitively inhibited miR-132 and -212 activity in luciferase rescue assays and showed greater stability than linear sponges. A design containing 12 bulged binding sites with 12 nucleotides spacing was determined to be optimal. Adeno-associated viruses (AAVs) were used to deliver circmiRs to cardiomyocytes in vivo in a transverse aortic constriction (TAC) mouse model of cardiac disease. Hypertrophic disease characteristics were attenuated, and cardiac function was preserved in treated mice, demonstrating the potential of circmiRs as novel therapeutic tools. Subsequently, group I permutated intron-exon sequences were used to directly synthesize exogenous circmiRs, which showed greater in vitro efficacy than the current gold standard antagomiRs in inhibiting miRNA function. Engineered circRNAs thus offer exciting potential as future therapeutics.
Mood Homeostasis, Low Mood, and History of Depression in 2 Large Population Samples

Journal: JAMA Psychiatry (2020)

Existing therapeutic options are insufficient to tackle the disease burden of depression, and new treatments are sorely needed. Defining new psychotherapeutic targets is challenging given the paucity of coherent mechanistic explanations for depression.To assess whether mood homeostasis (ie, the stabilization of one's mood by engaging in mood-modifying activities) is a possible new therapeutic target by testing the hypothesis that people with low (vs high) mean mood and people with (vs without) a history of depression have impaired mood homeostasis.The quantitative association between mood and daily activities was computed in 2 large case-control studies based on the 58sec data set (collected from December 1, 2012, to May 31, 2014, and analyzed from April 1 to 30, 2019), and the World Health Organization Study on Global Aging and Adult Health (WHO SAGE) data set (collected from January 1, 2007, to December 31, 2010, and analyzed from June 1 to 30, 2019). The 58sec data set consists of self-enrolled participants from high-income countries. The WHO SAGE data set consists of nationally representative participants in low- and middle-income countries recruited via cluster sampling.The main outcome (defined before data analysis) was the difference in mood homeostasis between people with high vs low mean mood (58sec data) and between people with vs without a history of depression (WHO SAGE data).A total of 28 212 participants from the 58sec data set (65.8% female; mean [SD] age, 28.1 [9.0] years) and 30 116 from the WHO SAGE data set (57.0% female; mean [SD] age, 57.8 [14.7] years) were included, for an overall study population of 58 328 participants. Mood homeostasis was significantly lower in people with low (vs high) mean mood (0.63 [95% CI, 0.45 to 0.79] vs 0.96 [95% CI, 0.96 to 0.98]; P < .001) and in people with (vs without) a history of depression (0.03 [95% CI, -0.26 to 0.24] vs 0.68 [95% CI, 0.55 to 0.75]; P < .001). In dynamic simulations, lower mood homeostasis led to more depressive episodes (11.8% vs 3.8% yearly risk; P < .001) that lasted longer (4.19 vs 2.90 weeks; P = .006).In this study, mood homeostasis appeared to have been impaired in people with low mood and in those with a history of depression. Mood homeostasis may therefore provide new insights to guide the development of treatments for depression.
The profile of peripheral blood lymphocyte subsets and serum cytokines in children with 2019 novel coronavirus pneumonia
Authors: Hui Li, Kailan Chen, Maochang Liu, Hua Xu, Qiong Xu
Journal: Journal of Infection (2020)

The study was aimed at investigating the characteristics of peripheral blood lymphocyte subsets and serum cytokines in children with 2019 novel coronavirus (2019-nCoV) pneumonia.Children with 2019-nCoV pneumonia or with respiratory syncytial virus (RSV) pneumonia were included. Data including lymphocyte subsets and serum cytokines were collected and analyzed.56 patients were included in the study, 40 children with 2019-nCoV pneumonia and 16 children with RSV pneumonia. Compared with children with RSV pneumonia, patients with 2019-nCoV pneumonia had higher count of CD3+8+ lymphocyte, higher percentages of CD3+, CD3+8+ lymphocytes and a lower percentage of CD19+ lymphocyte. The serum IL-10 level was significantly higher in children with RSV pneumonia. One 2019-nCoV pneumonia child who was with an obvious increase of IL-10 developed severe pneumonia.Immune response played a very important role in the development of 2019-nCoV pneumonia. The effective CD8+ T cell response might influence the severity of 2019-nCoV pneumonia. The adaptable change in IL-10 level might contribute to the relatively mild pneumonia symptoms in children with 2019-nCoV pneumonia and bacterial co-infection might be a risk factor of severe 2019-nCoV pneumonia.

Rationale: Use of ACEIs (angiotensin-converting enzyme inhibitors) and ARBs (angiotensin II receptor blockers) is a major concern for clinicians treating coronavirus disease 2019 (COVID-19) in patients with hypertension. Objective: To determine the association between in-hospital use of ACEI/ARB and all-cause mortality in patients with hypertension and hospitalized due to COVID-19. Methods and Results: This retrospective, multi-center study included 1128 adult patients with hypertension diagnosed with COVID-19, including 188 taking ACEI/ARB (ACEI/ARB group; median age 64 [interquartile range, 55–68] years; 53.2% men) and 940 without using ACEI/ARB (non-ACEI/ARB group; median age 64 [interquartile range 57–69]; 53.5% men), who were admitted to 9 hospitals in Hubei Province, China from December 31, 2019 to February 20, 2020. In mixed-effect Cox model treating site as a random effect, after adjusting for age, gender, comorbidities, and in-hospital medications, the detected risk for all-cause mortality was lower in the ACEI/ARB group versus the non-ACEI/ARB group (adjusted hazard ratio, 0.42 [95% CI, 0.19–0.92]; P =0.03). In a propensity score-matched analysis followed by adjusting imbalanced variables in mixed-effect Cox model, the results consistently demonstrated lower risk of COVID-19 mortality in patients who received ACEI/ARB versus those who did not receive ACEI/ARB (adjusted hazard ratio, 0.37 [95% CI, 0.15–0.89]; P =0.03). Further subgroup propensity score-matched analysis indicated that, compared with use of other antihypertensive drugs, ACEI/ARB was also associated with decreased mortality (adjusted hazard ratio, 0.30 [95% CI, 0.12–0.70]; P =0.01) in patients with COVID-19 and coexisting hypertension. Conclusions: Among hospitalized patients with COVID-19 and coexisting hypertension, inpatient use of ACEI/ARB was associated with lower risk of all-cause mortality compared with ACEI/ARB nonusers. While study interpretation needs to consider the potential for residual confounders, it is unlikely that in-hospital use of ACEI/ARB was associated with an increased mortality risk.

Journal: BMJ (2020)

Abstract Objective To estimate and compare progression rates to type 2 diabetes mellitus (T2DM) in women with gestational diabetes mellitus (GDM) and healthy controls. Design Systematic review and meta-analysis. Data sources Medline and Embase between January 2000 and December 2019, studies published in English and conducted on humans. Eligibility criteria for selecting studies Observational studies investigating progression to T2DM. Inclusion criteria were postpartum follow-up for at least 12 months, incident physician based diagnosis of diabetes, T2DM reported as a separate outcome rather than combined with impaired fasting glucose or impaired glucose tolerance, and studies with both a group of patients with GDM and a control group. Results This meta-analysis of 20 studies assessed a total of 1 332 373 individuals (67 956 women with GDM and 1 264 417 controls). Data were pooled by random effects meta-analysis models, and heterogeneity was assessed by use of the I 2 statistic. The pooled relative risk for the incidence of T2DM between participants with GDM and controls was estimated. Reasons for heterogeneity between studies were investigated by prespecified subgroup and meta-regression analyses. Publication bias was assessed by funnel plots and, overall, studies were deemed to have a low risk of bias (P=0.58 and P=0.90). The overall relative risk for T2DM was almost 10 times higher in women with previous GDM than in healthy controls (9.51, 95% confidence interval 7.14 to 12.67, P&lt;0.001). In populations of women with previous GDM, the cumulative incidence of T2DM was 16.46% (95% confidence interval 16.16% to 16.77%) in women of mixed ethnicity, 15.58% (13.30% to 17.86%) in a predominantly non-white population, and 9.91% (9.39% to 10.42%) in a white population. These differences were not statistically significant between subgroups (white v mixed populations, P=0.26; white v non-white populations, P=0.54). Meta-regression analyses showed that the study effect size was not significantly associated with mean study age, body mass index, publication year, and length of follow-up. Conclusions Women with a history of GDM appear to have a nearly 10-fold higher risk of developing T2DM than those with a normoglycaemic pregnancy. The magnitude of this risk highlights the importance of intervening to prevent the onset of T2DM, particularly in the early years after pregnancy.

Adapting to a Pandemic — Conducting Oncology Trials during the SARS-CoV-2 Pandemic
Authors: Aaron C. Tan, David M. Ashley, Mustafa Khasraw
Journal: Clinical Cancer Research (2020)

Abstract The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has necessitated changes in cancer care delivery as resources are reallocated. Clinical trials and other research activities are inevitably impacted. Start-up activities for new trials may be deferred and recruitment suspended. For patients already enrolled however, there are challenges in continuing treatment on trial. Regulatory bodies have issued guidance on managing clinical trials during the pandemic, including contingency measures for remote study visits, delivery of investigational product, and site monitoring visits. New cancer clinical trial practices during the SARS-CoV-2 pandemic include new risk assessment strategies, decentralized and remote trial coordination, data collection, and delegation of specific therapeutic activities. This experience could provide evidence of more feasible and cost-effective methods for future clinical trial conduct.
