Standards of perioperative management in total knee and hip arthroplasty procedures. A survey-based study. Part I: Preoperative management

Background Recent years have seen an increasing number of elective total knee (TKA) and hip arthroplasty (THA) procedures. Since a wide variety of methods and procedures are used in perioperative management, a survey-based study was carried out to identify the patterns of practice in Polish hospitals. Methods With the help of the LimeSurvey application, questionnaires for anaesthesio-logists and orthopaedists were prepared to gain insight into the preparation of patients for TKA and THA procedures and perioperative care. Questionnaires included both single and multiple-choice questions concerning among other things type of laboratory tests, additional examinations and consultations performed on a routine basis before elective TKA and THA procedures. Results A total of 162 medical centres took part in the study. Questionnaire responses were obtained from 93 (57%) orthopaedics teams and 112 (69%) anaesthesiology teams. A mean (standard deviation, SD) of 7.2 (3.5) laboratory tests are routinely ordered before surgery. For example, 47% of orthopaedists and 20% of anaesthesiologists order urinalysis, while 53% of orthopaedists and 26% of anaesthesiologists order a CRP test. Seventy-nine per cent of orthopaedists refer patients for at least one specialist consultation before the procedure. Dental consultation is requested by 40%, gynaecological consultation by 27%. Patient preoperative education is provided by 85% of orthopaedists and preoperative rehabilitation is prescribed by 46% of them. A total of 56% surveyed anaesthesiologists perform pre-anaesthetic evaluation upon patients’ hospital admission. Conclusions The study found that the number of examinations and specialist consultations conducted in Polish hospitals exceeded the scope of recommendations of scientific societies. Furthermore, the authors identified a need to standardise perioperative management in the form of Polish guidelines or recommendations, with the intention to improve patient safety and optimize health care expenses.
Age exacerbates the negative effect of depression on executive functioning in racial and ethnic minorities

Age and depression may interact to produce a “double jeopardy” for cognitive impairment, and executive functioning, in cognitively unimpaired aging. Few studies have considered middle age or the ethnoracial diversity of subjects, despite evidence of more severe cognitive outcomes in historically minoritized people. In this pilot study, we investigated the impact of age on depression-related cognitive impairment and the underlying brain volumes in middle-aged non-Hispanic White adults (116), and Hispanic and Black adults (60), with a total number of 176 adults. The result shows a significant interaction between age and depression for executive functioning, specifically for middle-aged Hispanic and Black adults, but not non-Hispanic White adults. Prefrontal cortex volumes, which were reduced in the Black and Hispanic compared to the non-Hispanic White adults, partially mediated the relationship between depression level and executive functioning, across age and ethnoracial group. Collectively, these results suggest that the negative impact of depression on executive functioning and Prefrontal cortex volumes integrity may be exacerbated by age and that historically minoritized people may be particularly sensitive to this double jeopardy.
An atlas of rational genetic engineering strategies for improved xylose metabolism in Saccharomyces cerevisiae

Xylose is the second most abundant carbohydrate in nature, mostly present in lignocellulosic material, and representing an appealing feedstock for molecule manufacturing through biotechnological routes. However, Saccharomyces cerevisiae—a microbial cell widely used industrially for ethanol production—is unable to assimilate this sugar. Hence, in a world with raising environmental awareness, the efficient fermentation of pentoses is a crucial bottleneck to producing biofuels from renewable biomass resources. In this context, advances in the genetic mapping of S. cerevisiae have contributed to noteworthy progress in the understanding of xylose metabolism in yeast, as well as the identification of gene targets that enable the development of tailored strains for cellulosic ethanol production. Accordingly, this review focuses on the main strategies employed to understand the network of genes that are directly or indirectly related to this phenotype, and their respective contributions to xylose consumption in S. cerevisiae, especially for ethanol production. Altogether, the information in this work summarizes the most recent and relevant results from scientific investigations that endowed S. cerevisiae with an outstanding capability for commercial ethanol production from xylose.
Revealing Sexual Dimorphism in Prolactin Regulation From Early Postnatal Development to Adulthood in Murine Models

Abstract Serum prolactin (PRL) levels exhibit a gradual rise both in male and female rats from birth to adulthood, with females consistently displaying higher levels compared to age-matched males. This pattern has traditionally been attributed to the development and maturation of endocrine and neuroendocrine networks responsible for regulating PRL synthesis and secretion. However, the effect of dopamine (DA), which acts as an inhibitory factor on lactotroph function, also increases from birth to puberty, particularly in females. Nonetheless, the secretion of PRL remains higher in females compared to males. On the other hand, the observed sex differences in serum PRL levels during early postnatal development cannot be attributed to the influence of estradiol (E2). While serum E2 levels gradually increase after birth, only after 45 days of life do the disparities in E2 levels between females and males become evident. These observations collectively suggest that neither the maturation of hypothalamic DA regulation nor the rise in E2 levels can account for the progressive and sustained elevation in serum PRL levels and the observed sexual dimorphism during postnatal development. This review highlights the importance of recent discoveries in animal models that shed light on inhibitory mechanisms in the control of PRL secretion within the pituitary gland itself, that is intrapituitary mechanisms, with a specific emphasis on the role of transforming growth factor β1 and activins in PRL secretion.
Late outcomes of renal denervation are more favourable than early ones: facts or fancies?

ABSTRACT Following second-generation randomized trials, there is evidence that renal denervation (RDN) decreases blood pressure (BP), although to a lesser extent than suggested in the initial controlled and observational studies. The recent publication of the 36-month follow-up of the Symplicity HTN-3 trial has raised expectations, suggesting increasing, late benefits of the procedure, despite initially negative results. These findings come after those obtained at 36 months in the sham-controlled trial SPYRAL HTN-ON MED and in the Global Symplicity Registry. However, they are susceptible to biases inherent in observational studies (after unblinding for sham-control) and non-random, substantial attrition of treatment groups at 36 months, and used interpolation of missing BPs. More importantly, in SPYRAL HTN-ON MED and Symplicity HTN-3, long-term BP changes in patients from the initial RDN group were compared with those in a heterogeneous control group, including both control patients who did not benefit from RDN and patients who eventually crossed over to RDN. In crossover patients, the last BP before RDN was imputed to subsequent follow-up. In Symplicity HTN-3, this particular approach led to the claim of increasing long-term benefits of RDN. However, comparison of BP changes in patients from the RDN group and control patients who did not undergo RDN, without imputation of BPs from crossover patients, does not support this view. The good news is that despite the suggestion of sympathetic nerve regrowth after RDN in some animal models, there is no strong signal in favour of a decreasing effect of RDN over time, up to 24 or even 36 months. Still, current data do not support a long-term increase in the effect of RDN and the durability of RDN-related BP reduction remains to be formally demonstrated.
Drugs with a negative impact on cognitive functions (Part 2): drug classes to consider while prescribing in CKD patients

ABSTRACT There is growing evidence that chronic kidney disease (CKD) is an independent risk factor for cognitive impairment, especially due to vascular damage, blood–brain barrier disruption and uremic toxins. Given the presence of multiple comorbidities, the medication regimen of CKD patients often becomes very complex. Several medications such as psychotropic agents, drugs with anticholinergic properties, GABAergic drugs, opioids, corticosteroids, antibiotics and others have been linked to negative effects on cognition. These drugs are frequently included in the treatment regimen of CKD patients. The first review of this series described how CKD could represent a risk factor for adverse drug reactions affecting the central nervous system. This second review will describe some of the most common medications associated with cognitive impairment (in the general population and in CKD) and describe their effects.
Prevalence of viral DNA in high-grade serous epithelial ovarian cancer and correlation with clinical outcomes

Introduction Currently 11 infectious agents are classified as carcinogenic but the role of infectious agents on outcomes of epithelial ovarian cancer is largely unknown. Objective To explore the association between infectious agents and ovarian cancer, we investigated the prevalence of viral DNA in primary ovarian cancer tumors and its association with clinical outcomes. Methods Archived tumors from 98 patients diagnosed with high-grade serous epithelial ovarian cancer were collected between 1/1/1994 and 12/31/2010. After DNA extraction, Luminex technology was utilized to identify polymerase chain reaction-amplified viral DNA for 113 specific viruses. Demographic data and disease characteristics were summarized using descriptive statistics. We used logistic regression and Cox proportional hazards model to assess associations between tumor viral status and disease outcome and between tumor viral presence and overall survival (OS), respectively. Results Forty-six cases (45.9%) contained at least one virus. Six highly prevalent viruses were associated with clinical outcomes and considered viruses of interest (VOI; Epstein-Barr virus 1, Merkel cell polyomavirus, human herpes virus 6b, and human papillomaviruses 4, 16, and 23). Factors independently associated with OS were presence of VOI (HR 4.11, P = 0.0001) and platinum sensitivity (HR 0.21, P<0.0001). Median OS was significantly decreased when tumors showed VOI versus not having these viruses (22 vs 44 months, P<0.0001). Women <70 year old with VOI in tumors had significantly lower median OS versus age-matched women without VOI (20 vs 57 months, P = 0.0006); however, among women ≥70 years old, there was no difference in OS by tumor virus status. Conclusions The presence of a VOI was significantly associated with a lower OS. These findings may have implications for clinical management of ovarian cancer but require additional studies.
Tamoxifen Response at Single-Cell Resolution in Estrogen Receptor–Positive Primary Human Breast Tumors

Abstract Purpose: In estrogen receptor–positive (ER+)/HER2− breast cancer, multiple measures of intratumor heterogeneity are associated with a worse response to endocrine therapy. We sought to develop a novel experimental model to measure heterogeneity in response to tamoxifen treatment in primary breast tumors. Experimental Design: To investigate heterogeneity in response to treatment, we developed an operating room-to-laboratory pipeline for the collection of live normal breast specimens and human tumors immediately after surgical resection for processing into single-cell workflows for experimentation and genomic analyses. Live primary cell suspensions were treated ex vivo with tamoxifen (10 μmol/L) or control media for 12 hours, and single-cell RNA libraries were generated using the 10X Genomics droplet-based kit. Results: In total, we obtained and processed normal breast tissue from two women undergoing reduction mammoplasty and tumor tissue from 10 women with ER+/HER2− invasive breast carcinoma. We demonstrate differences in tamoxifen response by cell type and identify distinctly responsive and resistant subpopulations within the malignant cell compartment of human tumors. Tamoxifen resistance signatures from resistant subpopulations predict poor outcomes in two large cohorts of ER+ breast cancer patients and are enriched in endocrine therapy–resistant tumors. Conclusions: This novel ex vivo model system now provides the foundation to define responsive and resistant subpopulations within heterogeneous human tumors, which can be used to develop precise single cell–based predictors of response to therapy and to identify genes and pathways driving therapeutic resistance.
Improving health literacy of antibiotic use in people with cystic fibrosis (CF)—comparison of the readability of patient information leaflets (PILs) from the EU, USA and UK of 23 CF-related antibiotics used in the treatment of CF respiratory infections

Abstract Background Antibiotic adherence is poor amongst people with cystic fibrosis (CF). Low-quality patient information leaflets (PILs), which accompany prescription antibiotics, with poor readability may contribute to poor antibiotic adherence, with the potential for antimicrobial resistance (AMR) development. The aim of this study was to examine the readability of antibiotic PILs used to treat CF lung infections. Methods CF-related antibiotics (n = 23; seven classes: aminoglycosides, β-lactams, fluoroquinolones, macrolides/lincosamides, oxazolidinones, tetracyclines, trimethoprim/sulfamethoxazole) were investigated. Readability of PILs (n = 141; 23 antibiotics) from the EU (n = 40), USA (n = 42) and UK (n = 59) was calculated. Results Mean [± standard error of mean (SEM)] values for the Flesch Reading Ease (FRE) for EU, USA and UK were 50.0 ± 1.1, 56.2 ± 1.3 and 51.7 ± 1.1, respectively (FRE target ≥60). Mean (± SEM) values for the Flesch Kinkaid Grade Level (FKGL) for the EU, USA and UK were 9.0 ± 0.2, 7.5 ± 0.2 and 9.6 ± 0.2, respectively (FKGL target ≤8). US PILs were significantly shorter (P < 0.0001) in words (mean ± SEM = 1365 ± 52), than either UK or EU PILs, with fewer sentences (P < 0.0001), fewer words per sentence (P < 0.0001) and fewer syllables per word. The mean ( ± SEM) reading time of UK PILs (n = 59) was 12.7 ± 0.55 mins . Conclusions Readability of antibiotic PILs is poor. Improving PIL readability may lead to improved health literacy, which may translate to increased antibiotic adherence and AMR avoidance. Authors preparing written materials for the lay/patient CF community are encouraged to employ readability calculators, so that final materials are within recommended readability reference parameters, to support the health (antibiotic) literacy of their readers.
Homologous Recombination: How RecA Finds the Perfect Partner

synthesis in the mushroom bodies upon robust and chronic developmental expression as one would expect, although defects in axonal structureswere observed. Thus, the RICIN transgene used may lack the potency necessary for making strong conclusions about the requirement for normal protein synthesis. A control experiment performed to test the potency of RICIN in blocking mushroom-body protein synthesis using the KAEDE reporter is questionable for two reasons. It remains unknown whether KAEDE expression offers a good surrogate for the hoped-for effect on the many endogenous proteins that are involved in LTM. In addition, the inhibition of KAEDE expression was monitored only in the cell bodies of the mushroom bodies. Protein synthesis underlying LTM is complex, being required in multiple cellular compartments, including the cell body, axons and dendrites. Whether the RICIN toxin had sufficient efficacy across all compartments is unknown. Finally, neurons are plastic and redundant. A large body of evidence has indicated that olfactory memory in insects is distributed across multiple nodes of the olfactory nervous system. There exist approximately 5000 mushroom body neurons, but only two DAL neurons. Mushroom bodies are remarkably resilient to insults. A genetic lesion that completely removes the vertical lobes leaves learning and memory after massed conditioning completely intact; one that removes the horizontal lobes leaves learning and memory after both spaced and massed conditioning intact [15]. Redundancy and/or plasticity of the mushroom bodies may allow insults to many of these neurons before phenotypic effects are observed, whereas insults to a node of the system comprising only two neurons would have immediately observable effects. We believe that past and current evidence from multiple insect species favors a model in which cellular consolidation, including the requirement for new protein synthesis, occurs at multiple nodes within the olfactory nervous system, with systems consolidation — which has not yet been demonstrated in Drosophila — overlaying consolidation at the cellular level [16]. The discovery by Chen et al. [5] that the DAL neurons comprise one of the nodes in the olfactory nervous system required for olfactory memory in the fly could prove to be an important contribution to our understanding of the circuitry underlying LTM, but prior studies showing that these neurons are important for heat sensation [17] cast doubt on their specificity for memory formation. Most importantly, the negative result with regard to mushroom bodies requires additional experiments. Until then, as the Spanish proverb says, ‘‘those you claim to be dead are in perfectly good health’’.
Partial cellular reprogramming: A deep dive into an emerging rejuvenation technology

Abstract Aging and age‐associated disease are a major medical and societal burden in need of effective treatments. Cellular reprogramming is a biological process capable of modulating cell fate and cellular age. Harnessing the rejuvenating benefits without altering cell identity via partial cellular reprogramming has emerged as a novel translational strategy with therapeutic potential and strong commercial interests. Here, we explore the aging‐related benefits of partial cellular reprogramming while examining limitations and future directions for the field.
Embryo Condition Media Collected from Polycystic Ovary Syndrome Patients with Abdominal Obesity Can Increase The Decidualization Potential of Healthy Endometrial Stromal Cells

Background: Polycystic ovary syndrome (PCOS) is a common endocrinological disorder associated with abdominal obesity (AO) and some reproductive complications including low pregnancy rate. Embryo-endometrium cross-talk has a key role in successful embryo implantation and subsequent normal pregnancy rate. The primary objective of this study is to evaluate the decidualization potential of endometrial stromal cells (ESCs) using the embryo condition media (ECM) collected from PCOS patients with AO, compared to ECM of those patients without AO. Materials and Methods: In this experimental study, we measured the capacity of ECM collected from PCOS patients with or without AO for decidualization induction in healthy ESCs after coculture. A total number of 53 embryos from 40 couples belonging to PCOS with AO, PCOS without AO, nonPCOS with AO, and nonPCOS without AO patients, were included in our study. The embryosof four groups were single-cultured up to the blastocyst stage. Their ECM (45λ/well) were pooled and added to healthy ESCs monolayer culture media to investigate their effects on decidualization potential via gene (PRL, IGFBP1, IL1-β, HOXA10, IL-6 and TNF-α) and protein (PRL, IGFBP1, IL1-β) expression analysis and ESCs migration assay. Results: The morphological analysis, migration assay (P≤0.0321), protein (P≤0.0139) and gene expression analysis showed PCOS with AO accounted for the highest gene (PRL, IGFBP1, IL1-β, HOXA10, IL-6, TNF-α) and protein markers (PRL, IGFBP1, IL1-β) (P≤0.05). NonPCOS individuals without AO had the lowest level of both gene and protein decidualization markers (P≤0.05). Conclusion: Considering decidualization as an inflammatory process, a higher level of decidualization markers was associated with a higher inflammatory status created by AO and PCOS, separately. Inflammation may disrupt the process of inflammatory to anti-inflammatory phase required for prevention of pregnancy loss, this could explain the high rate of abortion in these cases.

Experimental results show that this method has good effects on opposing the influences of lighting, shine, neon lighting, shadow of light.
Activation of the Nrf-2/HO-1 signalling axis can alleviate metabolic syndrome in cardiovascular disease

Abstract Background: Cardiovascular disease (CVD) is widely observed in modern society. CVDs are responsible for the majority of fatalities, with heart attacks and strokes accounting for approximately 80% of these cases. Furthermore, a significant proportion of these deaths, precisely one-third, occurs in individuals under 70. Metabolic syndrome encompasses a range of diseases characterized by various physiological dysfunctions. These include increased inflammation in adipose tissue, enhanced cholesterol synthesis in the liver, impaired insulin secretion, insulin resistance, compromised vascular tone and integrity, endothelial dysfunction, and atheroma formation. These factors contribute to the development of metabolic disorders and significantly increase the likelihood of experiencing cardiovascular complications.Method: We selected studies that proposed hypotheses regarding metabolic disease syndrome and cardiovascular disease (CVD) and the role of Nrf2/HO-1 and factor regulation in CVD research investigations based on our searches of Medline and PubMed.Results: A total of 118 articles were included in the review, 16 of which exclusively addressed hypotheses about the role of Nrf2 on Glucose regulation, while 16 involved Cholesterol regulation. Likewise, 14 references were used to prove the importance of mitochondria on Nrf2. Multiple studies have provided evidence suggesting the involvement of Nrf2/HO-1 in various physiological processes, including metabolism and immune response. A total of 48 research articles and reviews have been used to highlight the role of metabolic syndrome and CVD.Conclusion: This review provides an overview of the literature on Nrf2/HO-1 and its role in metabolic disease syndrome and CVD.
Subgraph extraction and graph representation learning for single cell Hi-C imputation and clustering

Abstract Single-cell Hi-C (scHi-C) technology enables the investigation of 3D chromatin structure variability across individual cells. However, the analysis of scHi-C data is challenged by a large number of missing values. Here, we present a scHi-C data imputation model HiC-SGL, based on Subgraph extraction and graph representation learning. HiC-SGL can also learn informative low-dimensional embeddings of cells. We demonstrate that our method surpasses existing methods in terms of imputation accuracy and clustering performance by various metrics.
