Existing guidelines and studies on the benefits of cerclage in twin pregnancies with a dilated cervix have low reliability and inconsistent conclusions. New randomized control trials and cohort studies focusing on twin pregnancies with cervical insufficiency were published recently. Therefore, this meta-analysis aimed to compare outcomes of cerclage placement and expectant treatment in twin pregnancies with a dilated cervix using recent data.

We screened the PubMed, Web of Science, ClinicalTrials.gov, and Cochrane Library databases to identify randomized controlled trials and cohort studies comparing maternal and perinatal outcomes of twin pregnancies with cervical dilation, with and without cerclage placement, published until December 2020. Estimates were pooled using random-effects or fixed-effect models depending on the heterogeneity. Mean difference, 95% confidence interval, and relative risk were used to compare the outcomes. The risk of bias was assessed using the Cochrane Handbook and the Newcastle-Ottawa Scale. The meta-analyses followed the guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines for systematic reviews of observational studies.

Five studies, comprising 275 twin pregnancies, met the inclusion criteria; of those, 167 underwent cerclage and 108 were expectantly managed. Cerclage placement significantly prolonged the interval from the time of diagnosis to delivery and reduced the incidence of preterm delivery, perinatal death, and complications. The fetal outcomes improved significantly in cases managed with cerclage.

Therefore, emergent cerclage is a potential option for managing twin pregnancies with cervical dilation of at least 1 cm.

This study aimed to evaluate the biological potential of A. cearensis leaves by antioxidant and in vitro cytogenotoxic analyses of ethanolic crude extract (EE) and its fractions in healthy human cells. The EE was obtained by percolation, followed by fractionation using dichloromethane, cyclohexane, ethyl acetate (EtOAc), and methanol (MeOH) as organic solvents. Extract and all fractions were evaluated for their antioxidant potential by DPPH and reducing power tests. In vitro cytotoxic activity was determined in human peripheral blood mononuclear cells by MTT assay for the extract, EtOAc and MeOH fractions. In turn, the genotoxic activity was determined in human lymphocytes by the Cytokinesis Block Micronucleus assay only for the EtOAc fraction. Only EtOAc fraction was analyzed via gas chromatography coupled to mass spectrometry due to its higher biological activity. Considering the antioxidant potential, the EtOAc fraction was most effective in DPPH (EC50 43.37 µg/mL) and reducing power (EC50 89.80 µg/mL) assays. GC-MS analysis of the EtOAc fraction led to the identification of guaiacol, 2,3-dihydro-benzofuran, 2-methoxy-4-vinylphenol, isovanillic acid methyl ester, 4-hydroxybenzaldehyde, and 4-(ethoxymethyl)-phenol. The EE (400-1000 µg/mL), EtOAc (≤150 µg/mL) and MeOH (50 and 150-600 µg/mL) fractions were not cytotoxic by MTT test. Additionally, the EtOAc fraction (100-400 µg/mL) did not induce significant genotoxic damage. Concentrations of the EtOAc fraction with antioxidant activity showed no cytotoxicity, nor genotoxicity potential, indicating them as a nontoxic natural antioxidant source.

Brain tumors (BT) are among the most prevalent cancers in recent years. Various studies have examined the diagnostic role of microRNAs in different diseases; however, their diagnostic role in BT has not been comprehensively investigated. This meta-analysis was performed to assess microRNAs in the blood of patients with BTs accurately.

Twenty-six eligible studies were included for analysis. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), area under curve (AUC), Q*index, summary receiver-operating characteristic (SROC) were assessed using the Meta-Disc V.1.4 and Comprehensive Meta-Analysis V.3.3 software.

The diagnostic accuracy of microRNA was high in identifying BT based on the pooled sensitivity 0.82 (95%CI 0.816-0.84), specificity 0.82 (95%CI 0.817-0.84), PLR 5.101 (95%CI 3.99-6.51), NLR 0.187 (95%CI 0.149-0.236), DOR 34.07 (95%CI 22.56-51.43) as well as AUC (0.92), and Q*-index (0.86). Subgroup analyses were performed for sample types (serum/plasma), reference genes (RNU6, miR-39, and miR-24), and region to determine the diagnostic power of microRNAs in the diagnosis of BT using pooled sensitivity, specificity, PLR, NLR, AUC, and DOR.

This meta-analysis suggested that circulating microRNAs might be potential markers for noninvasive early detection of BT.

Mental health difficulties are common among people with Huntington's disease (HD). However, such difficulties are only weakly associated with HD progression, suggesting their causes may be multifactorial rather than purely disease-related. find more Genetically unaffected family members have been shown to experience similar levels of mental distress to people with HD, potentially due to systemic stressors and life disruption. These factors may also influence mental wellbeing in people with HD. Accordingly, this study aimed to compare patterns and occurrence of mental distress between people with HD and genetically unaffected control groups, to determine systemic and environmental contributions to HD-related distress.

Exploratory and confirmatory factor analysis was used to compare the structure of mental distress in 5,294 individuals from four groups manifest or premanifest HD, family control, and genotype-negative. Data were from the Enroll-HD study, using scores from the Problem Behaviors Assessment, the Hospitalusly believed. This suggests contributions from systemic as well as genetic factors in families affected by HD, especially in terms of anxiety symptoms.

Motor imagery (MI), defined as the ability to mentally represent an action without actual movement, has been used to improve motor function in athletes and, more recently, in neurological disorders such as Parkinson's disease (PD). link2 Several studies have investigated the neural correlates of motor imagery, which change also depending on the action imagined.

This review focuses on locomotion, which is a crucial activity in everyday life and is often impaired by neurological conditions. After a general discussion on the neural correlates of motor imagery and locomotion, we review the evidence highlighting the abnormalities in gait control and gait imagery in PD patients. Next, new perspectives and techniques for PD patients' rehabilitation are discussed, namely Brain Computer Interfaces (BCIs), neurofeedback, and virtual reality (VR).

Despite the few studies, the literature review supports the potential beneficial effects of motor imagery interventions in PD focused on locomotion. The development of new technologies could empower the administration of training based on motor imagery locomotor tasks, and their application could lead to new rehabilitation protocols aimed at improving walking ability in patients with PD.

Polymicrobial biofilms were formed from saliva for 48 h under an intermittent exposure regime to 1% sucrose and in contact with films or tablets of gellan gum containing 2 mg of morin each. Acidogenicity, bacterial viability, dry weight and insoluble extracellular polysaccharides from biofilms were evaluated. The cytotoxicity of morin was evaluated in oral keratinocytes. Morin released from the systems reduced the viability of all the microbial groups evaluated, as well as the dry weight and insoluble polysaccharide concentration in the matrix and promoted the control of acidogenicity when compared with the control group without the substance. Morin was cytotoxic only at the highest concentration evaluated. In conclusion, morin is an effective agent and shows antimicrobial and anti-biofilm activity against polymicrobial biofilms.

To evaluate the visual outcomes, refractive outcomes and rotational stability of a toric piggyback intraocular lens (1stQ AddOn, GmbH, Mannheim, Germany) for astigmatic refractive error in pseudophakic eyes.

Visual and refractive outcomes were assessed based on the standard graphs for reporting refractive surgery outcomes. Rotational stability was assessed according to the Intraocular Lens (IOL) standards of the International Organisation for Standards.

Twenty-two eyes of 17 patients (age 65.1±9.3years) underwent toric piggyback IOL insertion. After a minimum follow-up of 3 months, 18 eyes (82%) achieved an uncorrected distance visual acuity (UDVA) of 0.00 logMAR (20/20) or better and all eyes achieved 0.1 logMAR (20/25). Mean UDVA improved from 0.27±0.03 to 0.12±0.03 and 0.04±0.04 at one and 3 months (all

<.05). Nineteen eyes (86%) achieved an UDVA at least equal to the pre-operative corrected distance visual acuity (CDVA). No eyes lost more than one line of CDVA. All eyes achieved within 0.5D ofstigmatic refractive error in pseudophakic eyes.Novel coronavirus disease, a serious challenge for the healthcare system, has diverted all the researchers toward the exploration of potential targets, compounds or vaccines for the management of this disease. Mpro enzyme was found to be crucial for replication of this virus which makes this enzyme an attractive drug target for SARS-CoV-2. Diverse pharmacological profile of Alkannin/shikonin (A/S) derivatives build up curiosity to study their antiviral profile. Therefore, current study utilises various computational tools to screen and evaluate all the discovered A/S derivatives to inhibit the Mpro enzyme for its anti-viral activity. Results revealed that the A/S has a very good tendency to inhibit the catalytic activity of the enzyme. Moreover, (5 R,6R)-5,8-dihydroxy-6-methoxy-3,4,5,6-tetrahydro-2H-benzo[a]anthracene-1, 7, 12-trione, an A/S derivative was found to possess drug-likeliness properties and a good ADME profile. Moreover, its complex with Mpro enzyme was found stable for 50 ns which makes it a very promising ligand to treat COVID-19.Temporal coordination of organisms according to the daytime allows a better performance of physiological processes. However, modern lifestyle habits, such as food intake during the rest phase, promote internal desynchronization and compromise homeostasis and health. The hypothalamic suprachiasmatic nucleus (SCN) synchronizes body physiology and behavior with the environmental light-dark cycle by transmitting time information to several integrative hypothalamic nuclei, such as the paraventricular nucleus (PVN), dorsomedial hypothalamic nucleus (DMH) and median preoptic area (MnPO). The SCN receives metabolic information mainly via Neuropeptide Y (NPY) inputs from the intergeniculate nucleus of the thalamus (IGL). Nowadays, there is no evidence of the response of the PVN, DMH and MnPO when the animals are subjected to internal desynchronization by restricting food access to the rest phase of the day. To explore this issue, we compared the circadian activity of the SCN, PVN, DMH and MnPO. link3 In addition, we analyzed the daily activity of the satiety centers of the brainstem, the nucleus of the tractus solitarius (NTS) and area postrema (AP), which send metabolic information to the SCN, directly or via the thalamic intergeniculate leaflet (IGL).
