Abstract
Background: Safer conception counseling (SCC) to promote safer conception methods (SCM) is not yet part of routine family planning or HIV care, and to date there are no published controlled evaluations of SCC.Methods: In a hybrid, cluster randomized controlled trial, six HIV clinics were randomly assigned to implement the SCC intervention Our Choice using either a high (SCC1) or low intensity (SCC2) approach, or existing family planning services (usual care). 389 HIV clients considering childbearing with an HIV-negative partner enrolled. The primary outcome was self-reported use of appropriate reproductive method (SCM if trying to conceive; modern contraceptives if not) over 12 months or until pregnancy. Results: The combined intervention groups used appropriate reproductive methods more than usual care [20.8% vs. 6.9%; adjusted OR (95% CI)=10.63 (2.79, 40.49)], and SCC1 reported a higher rate than SCC2 [27.1% vs. 14.6%; OR (95% CI)=4.50 (1.44, 14.01)]. Among those trying to conceive, the intervention arms reported greater accurate use of SCM compared to usual care [24.1% vs. 0%; OR (95% CI)=91.84 (4.94, 1709.0)], and SCC1 performed better than SCC2 [34.6% vs. 11.5%; OR (95% CI)=6.43 (1.90, 21.73)]; the arms did not vary on modern contraception use among those not trying to conceive. A cost of $631 per person was estimated to obtain accurate use of SCM in SCC1, compared to $1014 in SCC2. Conclusions: More intensive training and supervision leads to greater adoption of complex SCM behaviors and is more cost-effective than the standard implementation approach.Trial registration: Clinicaltrials.gov, NCT03167879; date registered May 23, 2017; https://clinicaltrials.gov/ct2/show/NCT03167879.

Abstract
Background: This study investigated the effects of piglets with dietary supplementation yeast fermentation product (YFP) on growth performance, immune status and intestinal inflammation after a Salmonella typhimurium challenge. Twenty-four weaned piglets were assigned to four treatments including: non-challenge control (Con); Salmonella typhimurium-challenged control (ST); ST + 0.2% YFP (0.2% YFP); and ST + 0.4% YFP (0.4% YFP). All piglets were challenged twice with Salmonella typhimurium. All of them were killed at 7th day after the second challenge to obtain plasma and intestine for analysis.Results: 0.4% YFP increased average daily gain (ADG) and duodenal villus height and villus height/ crypt depth (P < 0.05) and decreased feed-gain ratio (P < 0.05) after Salmonella typhimurium challenge compared with ST group. The 0.4% YFP decreased the elevating concentrations IL-1b and IL-6 (P < 0.01) induced by Salmonella typhimurium and increased the concentration of IL-10 (P < 0.05) in plasma compared with ST group. Furthermore, YFP influenced the apoptosis related mRNA levels of Bax, Bcl-2 and caspase 3 (P < 0.05) and increased intestinal occludin protein expression (P < 0.05). 0.4% YFP down-regulated the mRNA expressions of TLR4, MyD88, IRAK1, TRAF6 and NFkB (P < 0.05) and decreased the mRNA expression of IL-6, TNFa (P < 0.05) and increased the IL-10 (P < 0.01) in duodenum compared with ST group. In addition, 0.4% YFP decreased the phosphorylation levels of p38 MAPK and ERK1/2 (P < 0.01).Conclusions: Dietary 0.4% yeast fermentation product supplementation had positive effects on growth performance and intestinal barrier function and reduced intestinal inflammation of weaned piglets challenged with Salmonella typhimurium.

Abstract
Background: Glaucoma is a leading cause of blindness worldwide and is characterized by degeneration associated with the death of retinal ganglion cells (RGCs). It is believed that glaucoma is a group of heterogeneous diseases with multifactorial pathomechanisms. Here, we investigate whether anti-inflammation treatment with an ER stress blockade can selectively promote neuroprotection against NMDA injury in the RGCs.Methods: Retinal excitotoxicity was induced with an intravitreal NMDA injection. Microglial activation and neuroinflammation were evaluated with Iba1 immunostaining and cytokine gene expression. A stable HT22 cell line transfected with an NF-kB reporter was used to assess NF-kB activity after hesperidin treatment. CHOP-deficient mice were used as a model of ER stress blockade. Retinal cell death was evaluated with a TUNEL assay.Results: In the NMDA injury group, Iba1-positive microglia increased 6 h after NMDA injection. Also at 6 h, pro-inflammatory cytokines and chemokines increased, including TNFα, IL-1b, IL-6 and MCP-1. In addition, the MCP-1 promoter-driven EGFP signal, which we previously identified as a stress signal in injured RGCs, also increased; hesperidin treatment suppressed this inflammatory response and reduced stressed RGCs. In CHOP-deficient mice that received an NMDA injection, the gene expression of pro-inflammatory cytokines, chemokines, markers of active microglia, and inflammatory regulators was greater than in WT mice. In WT mice, hesperidin treatment partially prevented retinal cell death after NMDA injury; this neuroprotective effect was enhanced in CHOP-deficient mice.Conclusions: These findings demonstrate that ER stress blockade is not enough by itself to prevent RGC loss due to neuroinflammation in the retina, but it has a synergistic neuroprotective effect after NMDA injury when combined with an anti-inflammatory treatment based on hesperidin.

Abstract
The radula is the food gathering and processing structure and one important autapomorphy of the Mollusca. It is composed of a chitinous membrane with small, embedded teeth representing the interface between the organism and its ingesta. In the past, various approaches aimed at connecting the tooth shapes, which are highly distinct within single radulae due to their different functions. However, conclusions from the literature have been mainly drawn from microscopical analyses of mounted radulae, but the real interacting radular parts – even though the precise contact areas are essential for determining a tools functionality – and the 3D architecture of this complex feeding structure have not been previously determined. In the experimental approach presented here individuals of Vittina turrita (Neritidae, Gastropoda) were fed with algae paste attached to different sandpaper types. By comparison with radulae from a control group, sandpaper-induced tooth wear patterns were identified and both the area and volume loss were quantified. In addition to the exact contact area of each tooth, conclusions about the 3D position of teeth and the radular bending during feeding motion could be drawn. Furthermore, hypotheses about the specific functions of individual tooth types could be put forward. This kind of feeding experiments under controlled conditions is new for Mollusca and may provide a good basis for future studies on the radula functional morphology. It can be potentially applied to species with distinct tooth morphologies and ecological niches.

Abstract
Objectives: Neoadjuvant radiochemotherapy (nCRT) is universally considered to be a valid treatment to achieve downstaging, improve local disease control and obtain better resectability in locally advanced rectal cancer (LARC). The aim of this study is to correlate the change in tumor 18F -FDG PET-CT standardized uptake value (SUV) before and after nCRT, in order to obtain an early prediction of pathologic response (pR) achieved in patients with LARC.Data description: We performed a retrospective analysis of patients with LARC diagnosis who underwent curative resection. All patients received nCRT and surgical treatment was carried after 8/12th. All patients underwent a baseline 18F -FDG PET-CT scan within the week prior to the initiation of the treatment (PET-CT SUV1) and a second scan (PET-C T SUV2) within six weeks of the completion of nCRT. Furthermore, we evaluated the prognostic value of 18F -FDG PET-CT in terms of disease free survival (DFS) and overall survival (OS) in patients with LARC.A total of 133 patients with LARC were included in the study. Patients were divided in two groups according to the TRG (tumor regression grade): 107 (80%) as Responders group (TRG0-TRG1) and 26 (25%) as the No-Responders group (TRG2-TRG3). We obtained a significant difference in Δ%SUV between the two different groups responders vs no responders (p<0.012).The results of this analysis have shown that 18F-FDG PET-CT may be an indicator in order to evaluate the pR to nCRT in patients with LARC. The decrease in 18F-FDG PET-CT uptake in the primary tumor may offer primary information in order to early identify those patients more likely to obtain a pCR to nCRT and predict those unlikely to regress significantly.

Abstract
BackgroundThe modification of the gut microbiota by antibiotics may influence the disease susceptibility and immunological responses. Infants in the neonatal intensive care unit (NICU) subjected to frequent antibiotics and oxygen therapies, which may give rise to the local and systemic inflammatory reactions and progression of bronchopulmonary dysplasia (BPD). This study aimed to investigate the role of intestinal dysbacteriosis by antibiotic therapy before hyperoxia exposure in the progression of BPD.MethodsMice had been exposed to hyperoxia (85% O2) since postnatal day 3 until day 16 for the BPD model establishment, treated with antibiotics from postnatal day 2 until day 8. Treated mice and appropriate controls were harvested on postnatal day 10 for 16S rRNA gene sequencing, or postnatal day 17 for assessment of alveolar morphometry and macrophages differentiation.ResultsAntibiotic-induced intestinal dysbacteriosis before hyperoxia exposure gave rise to deterioration of BPD evidenced by reduced survival rates and alveolarization, moreover, antibiotic-induced intestinal dysbacteriosis resulted in increased iNOS and decreased Arg-1 levels in lung homogenates.ConclusionBroad-spectrum antibiotic-induced intestinal dysbacteriosis may participate in BPD pathogenesis via alteration of the macrophage polarization status. Manipulating the gut microbiota may potentially intervene the therapy of BPD.

Abstract
BackgroundGlossina (Tsetse flies) biologically transmit trypanosomes that infect both humans and animals. Knowledge of their distribution patterns is a key element to better understand the transmission dynamics of trypanosomosis. Tsetse distribution in Rwanda has not been well enough documented and little is known of their current distribution. This study determined the current spatial distribution, abundance, diversity, and seasonal variations of tsetse flies in and around the Akagera National Park.MethodsA longitudinal stratified sampling, following the seasons was used. Biconical traps were deployed in 55 sites for six consecutive days of each study month from May 2018 to June 2019, and emptied every 48hours. Flies were identified using FAO keys and the number of flies per trap day (FTD) was used to determine the apparent density. Pearson chi-square (χ2) and parametrical tests (t-test and ANOVA) were used to determine the variations between the variables. The significance (p< 0.05) at 95% confidence interval was considered. Logistic regression was used to determine the association between tsetse occurrence and the associated predictors. Results39,516 tsetse flies were collected, of which 73.4% and 26.6% were from inside Akagera NP and the interface area respectively. Female flies accounted for 61.3% while 38.7% were males. Two species were identified, i.e. G. pallidipes [n=29,121, 7.4 flies/trap/day (FTD)] and G. morsitans centralis (n=10,395; 2.6 FTD). The statistical difference in numbers was significant between the two species (p=0.000). The flies were more abundant during the wet season (15.8 FTD) than the dry season (4.2 FTD). Large numbers of flies were trapped around the swamp areas (69.1 FTD) inside the park and in Nyagatare District (11.2 FTD) at the interface. Glossina morsitans was 0.218 times less likely to occur outside the park. The chance of co-existing between the two species reduced outside the protected area (0.021 times).ConclusionsThe occurrence of Glossina seems to be limited to the protected Akagera NP and a narrow band in its surroundings. This finding will be crucial to design appropriate control strategies. Glossina pallidipes was found in higher numbers and therefore conceivably the most important vector of trypanosomosis. Regional coordinated control and regular monitoring of Glossina distribution are recommended.

Abstract
Background: We aimed to establish and validate a coagulation-feature-based nomogram to predict recurrence-free survival for prostate cancer patients.Methods: The study contained 168 prostate cancer patients who had received radical prostatectomy between 2012 and 2018. The Kaplan-Meier plot and log-rank analysis were used to screen recurrence-free survival-related features. The nomogram was established by combining the significant coagulation features with clinicopathological characteristics by using Cox regression analysis. The accuracy and clinical significance of the nomogram model were assessed by receiver operating characteristic (ROC) curve, Kaplan-Meier plot, and calibration plot. Besides, we explored the correlation between coagulation pathway activity and patients’ prognosis based on public datasets by using gene set variation analysis (GSVA) analysis.Results: The results suggested that patients in the high-risk subgroup showed unfavorable prognoses than those in the low-risk subgroup classified by the nomogram model in both the training (log-rank P < 0.0001) and validation (log-rank P = 0.0004) cohorts. The nomogram model exhibited high discriminative accuracy in the training cohort [1-year area under the curve (AUC) of 0.74, and 3-year AUC of 0.69], which was confirmed in the internal validation cohort (C-index = 0.651). Besides, the calibration plots confirmed good concordance for the prediction of recurrence-free survival at 1 and 3 years. Besides, the subgroup analyses confirmed the usage of this model in different clinicopathological subgroups. Finally, GSVA analyses suggested that patients with higher coagulation pathway scores mostly had unfavorable prognoses than those with lower scores, a result consistent with the findings obtained above.Conclusions: In conclusion, we develop a practical nomogram model for the recurrence-free survival predicting of prostate cancer patients. This model may offer clinicians prognostic assessments and facilitate personalized treatment.

Published: January 2021

Abstract
BackgroundGlobally, breast cancer is one of the most common cancers with poor prognosis. The Fanconi anemia (FA) pathway genes maintain genome stability and play important roles in human diseases, including cancer. However, the prognostic values and biological roles of FA pathway genes in breast cancer have not been clarified.MethodsIn this study, the ONCOMINE, UCSC Xena, UALCAN, Kaplan-Meier plotter, cBioPortal, GEPIA, GeneMANIA, DAVID and TIMER databases were used to investigate the transcriptional and survival data of FA pathway genes in patients with breast cancer.ResultsMost of the FA pathway genes were found to be significantly upregulated in breast cancer tissues when compared to normal tissues. Additionally, the elevated expression levels of FA pathway genes were significantly associated with poor survival outcomes in breast cancer patients. Through functional enrichment analysis, the FA pathway genes were positively associated with cell cycle and nucleoplasm and negatively correlated with SRP-dependent co-translational protein targeting to membrane and ribosome. Furthermore, the expression levels of FA pathway genes exhibited a significant positive association with immune infiltration.ConclusionThe FA pathway genes are potential prognostic biomarkers for breast cancer and may offer effective as well as new strategies for cancer management.

Abstract
In this study, we aimed to investigate the relationship of IKBKE rs15672 and BANK1 rs12640056 gene polymorphisms with systemic lupus erythematosus (SLE) susceptibility in China. A case-control study was performed on 567 SLE patients and 345 healthy controls. Six single nucleotide polymorphisms (rs15672, rs2296164, rs12640056, rs6842661, rs1957106 and rs2274064) and clinical features were analyzed. Genotyping was executed with improved multiplex ligation detection reaction assay. SNP rs15672 increased the risk (P = 0.028, OR = 1.25, 95%CI = 1.02–1.52) but rs12640056 decreased the risk of SLE (P = 0.015, OR = 0.78, 95%CI = 0.64–0.95). For rs15672, patients carrying allele A assumed high-level IL-6 (25.36 ± 4.64 vs 16.56 ± 2.95, P = 0.036) and IL-4 (12.06 ± 4.51 vs 4.88 ± 1.76, P = 0.047), but low-level granzyme B (14.07 ± 1.86 vs 18.38 ± 3.85, P = 0.023), IL-18 (267.39 ± 14.67 vs 348.57 ± 44.25, P = 0.002) and IL-33 (0.91 ± 0.26 vs 2.19 ± 1.35, P = 0.029). Organ injury showed that mutant genotype at rs15672 had high-prevalence of arthritis (32.02%) and serositis (34.78%), but low in neuropathy (9.09%). For rs12640056, patients carrying allele T assumed low-level IL-33 (0.46 ± 0.17 vs 2.16 ± 1.00, P = 0.009). In conclusion, gene polymorphisms of rs15672 and rs12640056 present relevant with susceptibility of SLE, and affect the expression of cytokine and organ injury.

Abstract
Background: Antithrombotic medications (antiplatelets and anticoagulants) reduce the risk of cardiovascular disease (CVD), but with the disadvantage of increasing bleeding risk. Ethnicity and socioeconomic deprivation are independent predictors of major bleeds among patients without CVD, but it is unclear whether they are also predictors of major bleeds among patients with CVD or atrial fibrillation (AF) after adjustment for clinical variables. Methods: Prospective cohort study of 488,107 people in New Zealand Primary Care (including 64,420 Māori, the indigenous people of New Zealand) aged 30-79 years who had their CVD risk assessed between 2007 and 2016. Participants were divided into three mutually exclusive subgroups: (1) AF with or without CVD (n=15,212), (2) CVD and no AF (n=43,790), (3) no CVD or AF (n=429,105). Adjusted hazards ratios (adjHRs) were estimated from Cox proportional hazards models predicting major bleeding risk for each of the three subgroups to determine whether ethnicity and socioeconomic deprivation are independent predictors of major bleeds in different cardiovascular risk groups. Results: In all three subgroups (AF, CVD, no CVD/AF), Māori (adjHR 1.63 [1.39-1.91], 1.24 [1.09-1.42], 1.57 [95% CI 1.45-1.70], respectively), Pacific people (adjHR 1.90 [1.58-2.28], 1.30 [1.12-1.51], 1.62 [95% CI 1.49-1.75], respectively) and Chinese people (adjHR 1.53 [1.08-2.16], 1.15 [0.90-1.47], 1.13 [95% CI 1.01-1.26], respectively) were at increased risk of a major bleed compared to Europeans, although for Chinese people the effect did not reach statistical significance in the CVD subgroup. Compared to Europeans, Māori and Pacific peoples were generally at increased risk of all bleed types (gastrointestinal, intracranial and other bleeds). An increased risk of intracranial bleeds was observed among Chinese and Other Asian people and, in the CVD and no CVD/AF subgroups, among Indian people. Increasing socioeconomic deprivation was also associated with increased risk of a major bleed in all three subgroups (adjHR 1.07 [95% CI 1.02-1.12, 1.07 [1.03-1.10], 1.10 [1.08-1.12], respectively, for each increase in socioeconomic deprivation quintile). Conclusion: Ethnicity and socioeconomic status should be considered in bleeding risk assessments to guide the use of antithrombotic medication for the management of AF and CVD.
