Abstract
Backgrounds: However there have been numerous investigations of intrascleral intraocular lens (IOL) fixation techniques, there is room for improvement in terms of simplifying complicated techniques and reducing the high levels of skill required. This study aimed to report a novel technique for sutureless intrascleral fixation of the IOL using retinal forceps with a 27-gauge trocar.Methods: Nineteen eyes of 18 patients underwent intrascleral fixation of the IOL from July 2018 to September 2019 were enrolled in this study. A 27-gauge trocar formed 3-mm scleral tunnels positioned at 4 and 10 o’clock, 2 mm from the corneal limbus. We used a 3-piece IOL haptic grasped by a 27-gauge retinal forceps and pulled from the 27-gauge trocar. The IOL was fixed by making a flange. Main outcome measures were visual acuity, corneal endothelial cell density, IOL tilt, decentration, predicted error of refraction and complications.Results: The 19 eyes were followed up for 1 month. The mean pre- and postoperative logMAR uncorrected visual acuity (UCVA) was 1.06 ± 0.63 and 0.40 ± 0.26, respectively (p<0.01), while the mean pre- and postoperative logMAR best corrected visual acuity (BCVA) was 0.27 ± 0.51 and 0.06 ± 0.15, respectively (p=0.09). The mean corneal endothelial cell density was 2406 ± 625 to 2004 ± 759 cells/mm2 at 1 month (p=0.13). The mean IOL tilt was 3.52 ± 3.00°, and the mean IOL decentration was 0.39 ± 0.39 mm. There was no correlation among IOL tilt, decentration and BCVA (p>0.05). The mean prediction error of the target refraction was –0.03 ± 0.93 D. The complications were vitreous hemorrhage (3 eyes), hyphema (1 eye), IOP elevation (1 eye), iris capture of the IOL (1 eye) and hypotony (2 eyes). No IOL dislocation occurred.Conclusions: IOL intrascleral fixation with a flange achieved good IOL fixation and visual outcome in the scleral tunnels created with the 27-gauge trocar.

Abstract
Background: Earlier we reported that the microRNA (miR)-155 expression in dendritic cells (DCs) from Behcet’s disease (BD) patients was decreased and affected cytokine production of DCs. In this study, we investigated the mechanisms whereby miR-155 regulates cytokine production by DCs.Methods: The formation of autophagosomes in DCs was detected by transmission electron microscopy. Western blotting was used to detect the protein levels of LC3, Beclin-1, P62, p-mTOR and p-Akt in DCs. TNF-α, IL-6 and IL-1β expression were investigated by ELISA. MiR-155 mimics were transfected to DCs to evaluate its effects on autophagy and cytokine production. RNA interference was used to downregulate the expression of TAB2.Results: The formation of autophagosomes was found in DCs of active BD patients. The expressions of LC3-Ⅱ, Beclin-1and P62 were significantly increased in DCs of active BD patients compared to that of inactive BD patients and healthy controls. The expressions of IL-6, IL-1β and TNF-α were significantly increased in DCs of active BD patients compared to that of healthy controls. The autophagy promoter (3-MA) and inhibitor (rapamycin) significantly decreased or increased the expression of TNF-α, IL-6 and IL-1β by DCs. The expression of LC3-Ⅱand Beclin-1 were significantly increased, but the expression of P62 proteins was decreased in DCs transfected with miR-155 mimics or after TAB2 was downregulated. The expression of TNF-α, IL-6 and IL-1β were decreased in DCs after miR-155 was upregulated or TAB2 was downregulated. The ratios of p-Akt/Akt and p-mTOR/mTOR were decreased in DCs after miR-155 was upregulated. Conclusions: These results suggest that miR-155 affects the production of TNF-α, IL-6 and IL-1β by DCs through activation of the Akt/mTOR signaling pathway and by affecting the process of autophagy.

Abstract
Background The aim of this retrospective study was to compare the efficacy and safety profile of a single XEN-microstent in different types of primary and secondary open angle glaucoma. Methods A single XEN microstent was implanted in patients with primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), pseudoexfoliation glaucoma (PEX) and secondary glaucoma (Sec.Gl). The intraocular pressure (IOP), the active substances of the applied IOP-lowering drugs, the best corrected visual acuity (BCVA) and the mean deviation (MD) of the perimetry were measured at baseline and at regular follow-ups, scheduled at 2 days and 1, 3, 6 and 12 months after surgery. Results 153 eyes were included in this analysis. 113 eyes were affected by POAG (74%), 5 eyes by NTG (3%), 22 eyes by PEX (14%) and 13 eyes by Sec.Gl (9%). Mean IOP decreased in all treatment groups during the 12 months of follow-up (complete group: 23.9±7.4 to 15.4±5.1 mmHg (p<0.01); POAG: 22.8±6.5 to 15.1±4.6 mmHg (p<0.01); NTG: 16.6±3.4 to 11.6±2.2 mmHg (p<0.05); PEX: 28.0±7.9 to 17.1±6.6 mmHg (p<0.01); Sec.Gl: 28.9±13.9 to 15.5±6.9 mmHg (p<0.05)). In the 153 eyes the average number of IOP-lowering drugs applied decreased from 2.6±1.2 to 0.8±1.3 12 months after surgery (p<0.01). BCVA and mean deviation of automated standard perimetry remained stable in all groups during follow-up. Conclusion As in eyes suffering from POAG, IOP and number of IOP-lowering drugs applied can be effectively reduced by XEN implantation in eyes suffering from NTG, PEX and secondary glaucoma while leaving BCVA and visual field unchanged.

Abstract
Background It was confirmed that alveolar hypercoagulation and fibrinolytic inhibition were associated with refractory hypoxemia in acute respiratory distress syndrome (ARDS), and NF-κB pathway was involved in this process. The purpose of the present study is to explore the effects and relevant mechanisms exerted by NEMO-binding domain peptide (NBDP) to alleviate alveolar hypercoagulation and fibrinolytic inhibition aroused by lipopolysaccharide in ARDS mice.
Materials and Methods Adult male BALB/c mice inhaled lipopolysaccharide (LPS, mg/L) to induce ARDS. 30 minutes before LPS administration, we treated the mice with increasing concentrations of intratracheally inhaled NBDP or saline aerosol. Six hours after LPS treatment, bronchoalveolar lavage fluids (BALF) were collected and then all mice were executed. We checked coagulation and fibrinolysis associated factors in lung tissues and in BALF as well. We simultaneously observed the activation of NF-κB signaling pathway as well.
Results NBDP pretreatment dose-dependently inhibited either the expressions of tissue factor (TF) and plasminogen activator inhibitor (PAI) 1 in lung tissues or the secretions of TF, PAI-1, thrombin-antithrombin complex (TAT) and promoted activated protein C (APC) secretion in BALF induced by LPS. LPS-induced high expression of pulmonary procollagen peptide type Ⅲ (PⅢP) was also declined by NBDP pretreatment in dose-dependent manner. Western blotting showed that NBDP pretreatment obviously attenuated LPS-induced IKKα/β, Iκα and NF-κB p65 activation. LPS-induced p65 DNA binding activity was inhibited by NBDP pretreatment either. We also noticed NBDP protected mice against LPS-induced lung injury in a dose-dependent manner.
Conclusions Our experimental findings demonstrate that NBDP dose-dependently ameliorated LPS-induced alveolar hypercoagulation and fibrinolytic inhibition through inhibiting NF-κB signaling pathway. NBDP is expected to be a new therapeutic target to correct the abnormalities of alveolar coagulation and fibrinolysis in ARDS.

Abstract
Background: Mild cognitive impairment (MCI) is an intermediate phase between normal cognitive ageing and overt dementia, with amnesic MCI (aMCI) being the dominant subtype. This study aims to synthesise the prevalence results of MCI and aMCI in community-dwelling populations in China through a meta-analysis and systematic review.Methods: The study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) protocol. English and Chinese studies published before 1 March 2020 were searched from ten electronic bibliographic databases. Two reviewers screened for relevance of the studies against the pre-defined inclusion and exclusion criteria and assessed the quality of the included studies using the Risk of Bias Tool independently. A random-effect model was adopted to estimate the prevalence of MCI and aMCI, followed by sub-group analyses and meta-regression. Sensitivity and publication bias tests were performed to verify the robustness of the meta-analyses.Results: A total of 41 studies with 112,632 participants were included in the meta-analyses. The Chinese community-dwelling populations over 55 years old had a pooled prevalence of 12.2% [95% confidence interval (CI): 10.6%, 14.2%] for MCI and 10.9% [95% CI: 7.7%, 15.4%] for aMCI, respectively. The prevalence of MCI increased with age. The American Psychiatric Association’s Diagnostic tool (DSM-IV) generated the highest MCI prevalence (13.5%), followed by the Petersen criteria (12.9%), and the National Institute on Aging Alzheimer’s Association (NIA-AA) criteria (10.3%). Women, rural residents, and those who lived alone and had low levels of education had higher MCI prevalence than others. ​Conclusion: Higher MCI prevalence was identified in community-dwelling older adult populations in China compared with some other countries, possibly due to more relaxed criteria being adopted for confirming the diagnosis. The study shows that aMCI accounts for 66.5% of MCI, which is consistent with findings of studies undertaken elsewhere.Systematic review registration number: PROSPERO CRD42019134686

Abstract
Background: To investigate long-term outcomes of prediction error after phacotrabeculectomy and to determine risk factors that may cause unstable prediction error after phacotrabeculectomy in glaucoma patients. Methods: A total 120 eyes of 120 patients who had underwent uncomplicated phacotrabeculectomy (combined group) or phacoemulsification (phaco-only group) were included. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) were measured before and after surgery, and anterior segment parameters including anterior chamber depth (ACD), lens vault (LV), and anterior vault (AV) measured using anterior-segment optical coherence tomography were compared between the two groups. The mean absolute error (MAE) at 3, 6, 12, and 24 months postoperatively were compared. Risk factors associated with unstable prediction error (MAE ≥ 0.5) were investigated in the combined group. Results: In both groups, BCVA was improved and IOP was decreased significantly. MAE at 3, 6, 12, 24 months postoperatively were not significantly different between two groups. The risk factors for unstable prediction error after 12 months of phacotrabeculectomy were old age and LV. Whereas, the only factor predicting unstable prediction error after 24 months of phacotrabeculectomy was LV. The cut-off value of LV for predicting unstable refractive error analyzed by the ROC curve was 0.855 mm. Conclusions: Phacotrabeculectomy may be an effective treatment with stable long-term outcomes of prediction error similar to phacoemulsification in patients with glaucoma. However, elderly patients or patients with large LV may be predisposed to unstable prediction error after phacotrabeculectomy.

Abstract
Background Here, Mesocestoides (M.) vogae infection in mice is proposed as a suitable experimental model for studying the immunity in the peritoneal cavity of mice. Methods To investigate the kinetics of immune parameters in M. vogae-infected mice, we detected, using flow cytometry, the expression of selected lymphoid and myeloid markers within the peritoneal cell population at day 0, 3, 6, 10, 14, 19, 25, 30 and 35 post-infection. Then, using ELISA, we analyzed the cytokine IFN-γ, TGF-β, IL-4 and IL-10 responses and the levels of anti-M. vogae IgG and IgM antibodies in the peritoneal lavage fluid. Cells isolated from peritoneal cavity were subjected to further molecular analysis. To assess cell activation, peritoneal cells were exposed to LPS, and culture supernatants were collected and assayed for the level of cytokines and production of nitrite. Ly6C+ and Ly6G+ cells were isolated using MACS from the peritoneal cells at day 35 post-infection. Both MACS-isolated subsets were co-cultured with preactivated T cells to measure their suppressive capacity. Next, the role of parasite excretory-secretory antigens on induction of CD11b+ myeloid cells with the suppressive phenotype and the production of IL-10 was examined.Results In the peritoneal cavity an initial increase of CD11b+Gr-1+F4/80highMHCIIhigh cells, NK, NKT cells and CD8+ cytotoxic T cells was observed in the first week of infection. At day 14 post-infection, an increase in the number of myeloid CD11b+Gr-1+ cells was detected, and most of this cell population expressed low levels of F4/80 and MHC II in later stages of infection, suggesting the impairment of antigen-presenting cell functions, probably through the excretory-secretory molecules. Moreover, we confirmed that peritoneal Gr1+ cells (Ly6C+ and Ly6G+ population) are phenotypically and functionally consistent with myeloid-derived suppressor cells. Metacestode infection elicited high levels of IL-10 and up-regulated of STAT-3 in peritoneal cells. A higher level of IgM suggests that this isotype may be predominant and is involved in the host protection.Conclusions M. vogae tetrathyridia induced the recruitment of immunosuppressive cell subsets, which may play a key role in the down-regulation of immune response in long-term parasitic diseases, and excretory-secretory antigens seem to be the main regulatory factor.

Abstract
Background: Hispanic/Latino individuals are less likely to receive optimal treatment for chronic kidney disease (CKD) than non-Hispanic whites. This may be particularly detrimental for women of reproductive age as CKD may increase risk for infertility, menstrual irregularities, and pregnancy loss. While these maternal outcomes have been associated with advanced CKD, their occurrence in mild CKD is unclear. Methods: Using baseline (2008-2011) and second study visit (2014-2017) data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), we assessed the association between CKD and self-reported infertility, cessation of menses, hysterectomy, and nonviable pregnancy loss (experienced at less than 24 weeks gestation) in women of reproductive age (18-45 years). Multivariable survey logistic regression analyses were used to compute prevalence odds ratios with 95% confidence intervals (OR, 95% CI). Results: Of the 2,589 women included (mean age 31.4 years), 4.6% were considered to have CKD. In adjusted analyses, women with CKD did not have a significantly increased odds of infertility (OR 1.02, 95% CI 0.42 - 2.49), cessation of menses (OR 1.25, 95% CI 0.52 - 3.04) or hysterectomy (OR 1.17, 95% CI 0.61 - 2.25) compared to those without CKD. In those with CKD, the adjusted odds of a nonviable pregnancy loss was increased when considering pregnancies occurring after baseline visit (OR 2.11, 95% CI 0.63 - 7.02) but not statistically significance. Conclusion: In our Hispanic/Latino cohort, the presence of mild CKD did not confer an additional risk of our outcomes of interest. Examining nonviable pregnancy loss after CKD diagnosis in a larger sample warrants further study.

Abstract
Background: Nutritional strategies for sows designed to reduce peripartum stress are suggested to support postpartum recovery and productivity. Spray-dried plasma (SDP) in sow feed has been reported to benefit sow and litter performance. Stressed animals fed diets with SDP have a more efficient immune response supporting animal recovery and health. The objectives of the present study using 452 sows (147 parity 1 sows, 148 parity 2 sows) were to determine if 0, 0.5 or 2.5% spray-dried porcine plasma (SDPP) in peripartum feed provided from entry in maternity through day 5 of lactation affects sow productivity and serological immune and oxidation status markers around parturition. Post-weaning sow productivity parameters including litter size at the next parturition was evaluated, but peripartum diets were only provided during the first parturition. Results: In the first parturition, total born litter size was lower (P < 0.05) especially for sows allotted to the peripartum diet with 2.5% SDPP. Percentage of stillborn pigs decreased quadratically (P < 0.05) for sows fed 0.5% or 2.5% SDPP compared to 0% SDPP in peripartum feed and this result was not affected by total born litter size. Serum glutathione peroxidase activity linearly increased (P < 0.01) with increased dietary SDPP for both prepartum and postpartum sampling periods. In the next parturition, total born pigs from combined data of parity 1 and 2 sows linearly increased (P < 0.05) and live born pigs tended (P = 0.09) to linearly increase as level of SDPP increased and this result was not affected by total born litter size in the first parturition. The change in total and live born pigs from the first to the next parturition linearly (P < 0.01) increased as dietary SDPP increased for parity 1 and 2 sows. Conclusions: The reduced percentage of stillborn pigs and increased litter size of parity 1 and 2 sows in the next parturition was independent of total born litter size in the first parturition suggesting SDPP in peripartum sow feed may have merit for reducing stillborn pigs and benefit litter size in the next parturition for parity 1 and parity 2 sows.

Published: December 2020

Abstract
Background: Williams Syndrome is a developmental disorder characterized by a variable intellectual disability. People with Williams Syndrome need the intervention of several clinical and educational specialists throughout their life. However, little is known about the impact produced by this disability in their immediate environment, especially in families. The purpose was to know the level of quality of life described by families with Williams Syndrome. Methods: The sample was made up of 33 families belong to Spanish Williams Syndrome Association who were evaluated using the Kidslife Scale. Their children and adolescents were between 4 and 20 years old. Eight main quality of life domains were evaluated: emotional well-being, physical well-being, material well-being, personal development, interpersonal relations, social inclusion, self-determination and rightsResults: The obtained data indicated that the degree and presence of intellectual disability did not homogeneously influence people’s quality of life, but many variables could alter their quality of life to a greater or lesser extent. There are no significant differences between quality of life areas but significant differences appeared for level of dependence in the self-determination subarea (p<.05). Conclusions: These results led us to analyse the social and emotional implications for families and their environment.

Abstract
Background: The concept of personalized therapy has been proven to be a promising approach. A popular technique is to utilize gold nanoparticles (AuNPs) as drug delivery vectors for cytotoxic drugs and small molecule inhibitors to target and eradicate oral cancer cells in vitro and in vivo . Both drug and nanocarrier designs play important roles in the treatment efficacy. In our study, we standardized the nanosystem regarding NPs type, size, surface ligands and coverage percentage leaving only the drugs mode of action as the confounding variable. We propose that similarly constructed nanoparticles (NPs) can selectively leverage different conjugated drugs irrelevant to their original mode of action. If proven, AuNPs may have a secondary role beyond bypassing cancer cell membrane and delivering their loaded drugs.
Methods: We conjugated 5- fluorouracil (5Fu), camptothecin (CPT), and a fibroblast growth factor receptor1-inhibitor (FGFR1i) to gold nanospheres (AuNSs). We followed their trajectories in Syrian hamsters with chemically induced buccal carcinomas.
Results: Flow cytometry and cell cycle data shows that 5Fu- and CPT- induced a similar ratio of S-phase cell cycle arrest as nanoconjugates and in their free forms. On the other hand, FGFR1i-AuNSs induced significant sub-G1 cell population compared with its free form. Despite cell cycle dynamics variability, there was no significant difference in tumor cells’ proliferation rate between CPT-, 5Fu- and FGFR1i- AuNSs treated groups. In our in vivo model, FGFR1i-AuNSs induced the highest tumor reduction rates followed by 5Fu- AuNSs. CPT-AuNSs induced significantly lower tumor reduction rates compared with the 5Fu- and FGFR1i- AuNSs despite showing similar proliferative rates in tumor cells.
Conclusions: Our data indicates that the cellular biological events do not predict the outcome seen in our in vivo model. Furthermore, our results suggest that AuNSs selectively enhance the therapeutic effect of small molecule inhibitors such as FGFR1i than potent anticancer drugs. Future studies are required to better understand the underlying mechanism.
