RESUMO
Arylamines are essential building blocks for the manufacture of valuable pharmaceuticals, pigments and dyes. However, their current industrial production involves the use of chemocatalytic procedures with a significant environmental impact. As a result, flavin-dependent nitroreductases (NRs) have received increasing attention as sustainable catalysts for more ecofriendly synthesis of arylamines. In this study, we assessed a novel NR from Bacillus tequilensis, named BtNR, for the synthesis of pharmaceutically relevant arylamines, including valuable synthons used in the manufacture of blockbuster drugs such as vismodegib, sonidegib, linezolid and sildenafil. After optimizing the enzymatic reaction conditions, high conversion of nitroaromatics to arylamines (up to 97 %) and good product yields (up to 56 %) were achieved. Our results indicate that BtNR has a broad substrate scope, including bulky nitro benzenes, nitro pyrazoles and nitro pyridines. Hence, BtNR is an interesting biocatalyst for the synthesis of pharmaceutically relevant amine-functionalized aromatics, providing an attractive alternative to traditional chemical synthesis methodologies.

Extravasation is a fundamental step in the metastatic journey, where cancer cells exit the bloodstream and breach the endothelial cell barrier to infiltrate target tissues. The tactics cancer cells employ are sophisticated, closely reflecting those used by the immune system for tissue surveillance. Remarkably, tumor cells have been observed to form distinct associations or clusters with immune cells where neutrophils stand out as particularly crucial partners. These interactions are not accidental; they are critical for cancer cells to exploit the immune functions of neutrophils and successfully extravasate. In another strategy, tumor cells mimic the behavior and characteristics of immune cells. They release a suite of inflammatory mediators, which under normal circumstances, guide the processes of endothelium reshaping and facilitate the entry and movement of immune cells within tissues. In this review, we offer a new perspective on the tactics employed by cancer cells to extravasate and infiltrate target tissues. We delve into the myriad mechanisms that tumor cells borrow, adapt, and refine from the immune playbook. Video Abstract.

Video slot machines (VSM) are considered a particularly harmful gambling format; however, scant data is available on their use among underage Italian individuals. Two surveys were conducted in 2018 and 2022 involving 7,959 underage high school students (57.8% female) in Pavia, Northern Italy. We estimated adjusted odds ratios (aOR) and corresponding 95% confidence intervals (CI) for lifetime experience and current regular (at least monthly) use of VSM, according to family, educational and behavioral factors. Overall, participants reporting lifetime VSM experience were 13.2% (95% CI: 12.5 - 13.9), 15.2% (95% CI: 14.0-16.4%) in 2018, and 12.0% (95% CI: 11.1-13.0%) in 2022. Current regular VSM users were 1.4% (95% CI: 1.1-1.7) in total, 1.2% (95% CI: 0.8-1.6%) in 2018 and 1.5% (95% CI: 1.1-1.8%) in 2022. VSM lifetime experience and current regular use were significantly more frequent in males (aORs: 1.55 and 4.81, respectively), students who failed a year (aORs: 2.07 and 3.44), or with daily gambling parents/siblings (aORs: 2.83 and 4.86). Lifetime use of alcohol, tobacco, or illicit substances was significantly directly associated with lifetime VSM use (aORs between 2.64 and 4.75); monthly alcohol, tobacco, or illicit substances use was significantly directly associated with current regular VSM use (aORs between 4.47 and 18.21). Sexting and voluntary self-injury were significantly more frequent among VSM lifetime/current regular users. VSM use, which is directly associated with other risky behaviors, may be pervasive among Italian minors. Such public health concern calls for legislative enforcements and integrated multidisciplinary health promotion and prevention strategies.
RESUMO
Most flavin-dependent enzymes contain a dissociable flavin cofactor. We present a new approach for installing in vivo a covalent bond between a flavin cofactor and its host protein. By using a flavin transferase and carving a flavinylation motif in target proteins, we demonstrate that "dissociable" flavoproteins can be turned into covalent flavoproteins. Specifically, four different flavin mononucleotide-containing proteins were engineered to undergo covalent flavinylation: a light-oxygen-voltage domain protein, a mini singlet oxygen generator, a nitroreductase, and an old yellow enzyme-type ene reductase. Optimizing the flavinylation motif and expression conditions led to the covalent flavinylation of all four flavoproteins. The engineered covalent flavoproteins retained function and often exhibited improved performance, such as higher thermostability or catalytic performance. The crystal structures of the designed covalent flavoproteins confirmed the designed threonyl-phosphate linkage. The targeted flavoproteins differ in fold and function, indicating that this method of introducing a covalent flavin-protein bond is a powerful new method to create flavoproteins that cannot lose their cofactor, boosting their performance.

INTRODUCTION: Since satisfaction with cancer screening experience can increase adherence to programs and contribute to reduce morbidity and mortality, its assessment is crucial for programs´ effectiveness. Our aim was to conduct a systematic review about satisfaction of participants with organized colorectal cancer screening. METHODS: We searched relevant scientific databases (MEDLINE, EMBASE, PsycINFO, and CINAHL) from inception to May 2022. We selected cross-sectional studies and clinical trials reporting a quantitative survey-based measure of satisfaction towards CRC screening. RESULTS: A total of 15 studies were included, being published from 1992 to 2019 for an overall number of 21 surveys. Of those, 16 (76%) investigated satisfaction with screening tests (fecal occult blood test, fecal immunochemical test, sigmoidoscopy, colonoscopy, computed tomographic colonography), 4 (19%) with colonoscopy as assessment test after suspicious findings, and 2 (10%) with both the screening and assessment phase. None of the included surveys used a validated questionnaire. Most surveys reported a high level of satisfaction for both screening and further assessment phases. Temporary pain, discomfort, embarrassment, and anxiety while waiting for results were the commonest negative aspects perceived, with some variability across studies and considered procedures. CONCLUSIONS: Satisfaction with the information and communication about screening was generally good, but some authors reported participants' sub-optimal understanding of informative material. Satisfaction with CRC screening is generally high, but its evaluation is performed using non-validated instruments, which limits the interpretation of results and prevents comparability of the current body of evidence.
RESUMO
PURPOSE: The healthcare needs of parents of adolescents with congenital heart disease (CHD) have been under-investigated as no valid and reliable tools have been developed for assessing their needs. Therefore, this study aims to develop and validate the Parents' Healthcare Needs Scale for adolescents with CHD (PHNS-CHD). DESIGN AND METHODS: A multi-method approach and multi-phase design were employed. Phase one referred to generating scale items based on emerging themes in the literature, and phase two showed the validation process, divided into three steps. Step one tested the content and face validity of the first version of the PHNS-CHD. After that, step two described the initial psychometric validation process of scale using an exploratory factorial analysis (EFA). Then, step three confirmed the PHNS-CHD factorial structure and assessed its internal consistency. RESULTS: The PHNS-CHD showed evidence of face and content validity, adequate construct, and internal consistency and stability. Specifically, it had 22 items grouped into five domains, labeled as follows: Healthcare education to the child; to be supported as a parent, clinical support to the child, the continuum of care to the child; emotional support to the child. CONCLUSIONS: The PHNS-CHD is a psychometrically robust measure for assessing the healthcare needs of parents of adolescents with CHD. PRACTICE IMPLICATIONS: The PHNS-CHD might help clinicians, especially pediatric nurses, assess the healthcare needs of parents of adolescents with CHD and design adequate care plans for the whole family.
RESUMO
The uterine electromyogram, also called electrohysterogram (EHG), is the electrical signal generated by uterine contractile activity. The EHG has been considered an expanding technique for pregnancy monitoring and preterm risk evaluation. Data were collected on the abdominal surface. It has been speculated the effect of the placenta location on the characteristics of the EHG. In this work, a preliminary exploration method is proposed using the average spectra of Alvarez waves contractions of subjects with anterior and non-anterior placental position as a basis for the triple-dispersion Cole model that provides a best fit for these two cases. This leads to the uterine impedance estimation for these two study cases. Non-linear least square fitting (NLSF) was applied for this modelling process, which produces electric circuit fractional models' representations. A triple-dispersion Cole-impedance model was used to obtain the uterine impedance curve in a frequency band between 0.1 and 1 Hz. A proposal for the interpretation relating the model parameters and the placental influence on the myometrial contractile action is provided. This is the first report regarding in silico estimation of the uterine impedance for cases involving anterior or non-anterior placental positions.

The electrohysterogram (EHG) is the uterine muscle electromyogram recorded at the abdominal surface of pregnant or non-pregnant woman. The maternal respiration electromyographic signal (MR-EMG) is one of the most relevant interferences present in an EHG. Alvarez (Alv) waves are components of the EHG that have been indicated as having the potential for preterm and term birth prediction. The MR-EMG component in the EHG represents an issue, regarding Alv wave application for pregnancy monitoring, for instance, in preterm birth prediction, a subject of great research interest. Therefore, the Alv waves denoising method should be designed to include the interference MR-EMG attenuation, without compromising the original waves. Adaptive filter properties make them suitable for this task. However, selecting the optimal adaptive filter and its parameters is an important task for the success of the filtering operation. In this work, an algorithm is presented for the automatic adaptive filter and parameter selection using synthetic data. The filter selection pool comprised sixteen candidates, from which, the Wiener, recursive least squares (RLS), householder recursive least squares (HRLS), and QR-decomposition recursive least squares (QRD-RLS) were the best performers. The optimized parameters were L = 2 (filter length) for all of them and λ = 1 (forgetting factor) for the last three. The developed optimization algorithm may be of interest to other applications. The optimized filters were applied to real data. The result was the attenuation of the MR-EMG in Alv waves power. For the Wiener filter, power reductions for quartile 1, median, and quartile 3 were found to be -16.74%, -20.32%, and -15.78%, respectively (p-value = 1.31 × 10-12).

The addition of a common amino acid, phenylalanine, to a Layer-by-Layer (LbL) deposited polyelectrolyte (PE) film on a nanoporous membrane can increase its ionic selectivity over a PE film without the added amino acid. The addition of phenylalanine is inspired by detailed knowledge of the structure of the channelrhodopsins family of protein ion channels, where phenylalanine plays an instrumental role in facilitating sodium ion transport. The normally deposited and crosslinked PE films increase the cationic selectivity of a support membrane in a controllable manner where higher selectivity is achieved with thicker PE coatings, which in turn also increases the ionic resistance of the membrane. The increased ionic selectivity is desired while the increased resistance is not. We show that through incorporation of phenylalanine during the LbL deposition process, in solutions of NaCl with concentrations ranging from 0.1 to 100 mM, the ionic selectivity can be increased independently of the membrane resistance. Specifically, the addition is shown to increase the cationic transference of the PE films from 81.4% to 86.4%, an increase on par with PE films that are nearly triple the thickness while exhibiting much lower resistance compared to the thicker coatings, where the phenylalanine incorporated PE films display an area specific resistance of 1.81 Ω cm2 in 100 mM NaCl while much thicker PE membranes show a higher resistance of 2.75 Ω cm2 in the same 100 mM NaCl solution.

There is considerable interest in understanding what makes an individual vulnerable or resilient to the deleterious effects of stressful events. From candidate genes, dopamine (DA) and dopamine transporter (DAT) have been linked to anxiety, depression, and post-traumatic stress disorder. We investigated role of DAT using the new DAT heterozygous (DAT-HET) and homozygous mutant (DAT-KO) rat models of hyperdopaminergia. We studied the impact of two breeding conditions in spontaneous locomotor behavior of female rats. The classical colony, through mating DAT-HET males × DAT-HET females (breeding HET-HET), was used. A second WT colony was derived and maintained (breeding WT-WT). Additionally, a subgroup of rats was bred through mating DAT-KO males × WT females (atypical HET, breeding KO-WT). We studied the effects of genotype and its interaction with maternal care (depending by breeding condition). HET-HET breeding led to reduced activity in HET females compared to WT rats (from WT-WT breeding). However, HET females from KO-WT breeding did not differ so much from WT rats (WT-WT breeding). The maternal-care impact was then confirmed: HET mothers (breeding HET-HET) showed reduced liking/grooming of pups and increased digging away from nest, compared to WT mothers (breeding WT-WT). In their female offspring (HET, breeding HET-HET vs. WT, breeding WT-WT), isolation plus wet bedding induced higher and more persistent impact on activity of HET rats, even when the stressor was removed. Our results highlight the importance of epigenetic factors (e.g., maternal care) in responses to stress expressed by offspring at adulthood, quite independently of genotype. DAT hypofunction could determinate vulnerability to stressful agents via altered maternal care.

Over the past 40 years, the prevalence of obesity has risen dramatically, reaching epidemic proportions. By 2030 the number of people affected by obesity will reach 1.12 billion worldwide. Gastrointestinal hormones, namely incretins, play a vital role in the pathogenesis of obesity and its comorbidities. GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1), which are secreted from the intestine after nutrient intake and stimulate insulin secretion from pancreatic ß cells, influence lipid metabolism, gastric empting, appetite and body weight. The gut microbiota plays an important role in various metabolic conditions, including obesity and type 2 diabetes and influences host metabolism through the interaction with enteroendocrine cells that modulate incretins secretion. Gut microbiota metabolites, such as short-chain fatty acids (SCFAs) and indole, directly stimulate the release of incretins from colonic enteroendocrine cells influencing host satiety and food intake. Moreover, bariatric surgery and incretin-based therapies are associated with increase gut bacterial richness and diversity. Understanding the role of incretins, gut microbiota, and their metabolites in regulating metabolic processes is crucial to develop effective strategies for the management of obesity and its associated comorbidities.

Over the past 40 years, the prevalence of obesity has risen dramatically, reaching epidemic proportions. Metabolic surgery has proven to be highly effective in treating obesity, leading to significant improvements or complete resolution of obesity-related comorbidities. Research conducted in both animals and humans suggests that the metabolic benefits achieved through metabolic surgery cannot be solely attributed to weight loss. Indeed, there has been an increasing recognition of intestinal inflammation as a novel factor influencing obesity. The gastrointestinal tract is continuously exposed to dietary components, particularly diets rich in saturated fats, which are known to contribute to obesity. It is now widely accepted that heat shock proteins can be released from various cells including intestinal epithelial cells and act as proinflammatory signals. Several studies have shown that circulating levels of glucose-regulated protein 78 (GRP78) are increased in subjects with obesity and correlate with the severity of the disease. Moreover, mice with a partial knockout of GRP78 are protected from diet-induced obesity. In this review, we discuss the role of GRP78 in the development of obesity. Several evidence suggests that GRP78 can influence adipogenesis, lipid droplets stabilization, insulin resistance, and liver steatosis. We also provide an update on GRP78 regulation following metabolic surgery, focusing on the bypass of the small intestine as a key factor for GRP78 secretion. Finally, we discuss the potential role of monoclonal antibodies against GRP78 as a treatment for obesity.

OBJECTIVE: The general aim of the present study was the exploration of the relationships between childhood trauma subdimensions (physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect), unbalanced family functioning patterns (disengaged, enmeshed, rigid, and chaotic), and love addiction. METHOD: A sample of 910 individuals (76.6% female; Mage = 30 years, SD = 10.55) engaged in a romantic relationship participated in the research and completed the Love Addiction Inventory-Short Form, Family Adaptability and Cohesion Evaluation Scales-IV, and Childhood Trauma Questionnaire-Short Form. RESULTS: Among the childhood trauma subdimensions, emotional and physical abuse showed significant and positive associations with love addiction levels. Furthermore, the path analysis showed that unbalanced family functioning patterns parallelly mediated the relationship between emotional (enmeshed, rigid, and chaotic patterns) and physical abuse (chaotic patterns) and love addiction. Gender as a covariate was controlled for. CONCLUSIONS: The present study offers insight into the mechanisms by which specific forms of childhood trauma could lead to love addiction in adulthood. The findings offer valuable insights for developing customized interventions when working with individuals struggling with love addiction, as well as for implementing effective preventive activities for the condition.

RESUMO
Nitroreductases (NRs) are NAD(P)H-dependent flavoenzymes that reduce nitro aromatic compounds to their corresponding arylamines via the nitroso and hydroxylamine intermediates. Because of their broad substrate scope and versatility, NRs have found application in multiple fields such as biocatalysis, bioremediation, cell-imaging and prodrug activation. However, only a limited number of members of the broad NR superfamily (> 24 000 sequences) have been experimentally characterized. Within this group of enzymes, only few are capable of amine synthesis, which is a fundamental chemical transformation for the pharmaceutical, agricultural, and textile industries. Herein, we provide a comprehensive description of a recently discovered NR from Bacillus tequilensis, named BtNR. This enzyme has previously been demonstrated to have the capability to fully convert nitro aromatic and heterocyclic compounds to their respective primary amines. In this study, we determined its biochemical, kinetic and structural properties, including its apparent melting temperature (Tm) of 59 °C, broad pH activity range (from pH 3 to 10) and a notably low redox potential (-236 ± 1 mV) in comparison to other well-known NRs. We also determined its steady-state and pre-steady-state kinetic parameters, which are consistent with other NRs. Additionally, we elucidated the crystal structure of BtNR, which resembles the well-characterized Escherichia coli oxygen-insensitive NAD(P)H nitroreductase (NfsB), and investigated the substrate binding in its active site through docking and molecular dynamics studies with four nitro aromatic substrates. Guided by these structural analyses, we probed the functional roles of active site residues by site-directed mutagenesis. Our findings provide valuable insights into the biochemical and structural properties of BtNR, as well as its potential applications in biotechnology.
RESUMO
BACKGROUND AND OBJECTIVE: In an effort to limit the risks associated with medical radiation exposure, the last century witnessed the development of dose control mechanisms, recommended by the International Commission on Radiological Protection. This organization recommends the optimization of radiation protection to provide the highest level of safety that may reasonably be achievable. Adhering to the "as low as reasonably achievable" principle, the purpose of this study was to monitor the 18F-FDG injected activity in PET and optimize the radiation protection through an internal audit process. This monitoring allows the identification of opportunities for improvement in patient care and safety, as well as to establish a periodic review of the medical unit reference levels. METHODS: The methodology is based on short run Quesenberry (Q) statistics and normalized nonconstant sample size (Z-chart) control charts. Anonymized data from 512 patients were selected from a set of 18F-FDG PET/CT (Siemens, Biograph 6) examinations performed during 10 months. The analyzed variable was the ratio between the 18F-FDG injected activity (MBq) and patient weight (kg). RESULTS: Mean injected 18F-FDG activity was 347.811 ± 64.967 MBq corresponding to a mean effective dose of 6.608 ± 1.234 mSv. The ratio between the 18F-FDG injected activity and the body mass of patients was reduced from 5.243 ± 0.716 to 5.171 ± 0.672 MBq/kg during the statistical data analysis. The study demonstrates that control charts can be a useful tool to signal situations where patients receive an activity significantly different from the standard practice in a medical unit. CONCLUSION: The use of joint control charts is a suitable tool for detecting nonoptimized radiopharmaceutical administration. This analysis provides opportunities to evaluate and improve the quality of practice in nuclear medicine. This methodology constitutes an internal audit that may help health care professionals to make appropriate decisions to ensure all patients receive the safest and most appropriate care.
RESUMO
Macrophages are key immune cells that can adapt their metabolic phenotype in response to different stimuli. Lysine deacetylases are important enzymes regulating inflammatory gene expression and lysine deacetylase inhibitors have been shown to exert anti-inflammatory effects in models of chronic obstructive pulmonary disease. We hypothesized that these anti-inflammatory effects may be associated with metabolic changes in macrophages. To validate this hypothesis, we used an unbiased and a targeted proteomic approach to investigate metabolic enzymes, as well as liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry, to quantify metabolites in combination with the measurement of functional parameters in primary murine alveolar-like macrophages after lipopolysaccharide-induced activation in the presence or absence of lysine deacetylase inhibition. We found that lysine deacetylase inhibition resulted in reduced production of inflammatory mediators such as tumor necrosis factor α and interleukin 1ß. However, only minor changes in macrophage metabolism were observed, as only one of the lysine deacetylase inhibitors slightly increased mitochondrial respiration while no changes in metabolite levels were seen. However, lysine deacetylase inhibition specifically enhanced expression of proteins involved in ubiquitination, which may be a driver of the anti-inflammatory effects of lysine deacetylase inhibitors. Our data illustrate that a multiomics approach provides novel insights into how macrophages interact with cues from their environment. More detailed studies investigating ubiquitination as a potential driver of lysine deacetylase inhibition will help developing novel anti-inflammatory drugs for difficult-to-treat diseases such as chronic obstructive pulmonary disease.

OBJECTIVES: This umbrella review aimed to consolidate the evidence base on the impact of high-fidelity simulation on knowledge and performance among undergraduate nursing students. DESIGN: Umbrella review with meta-analyses of pooled effect sizes, followed by an additional meta-analysis of primary studies from the included systematic reviews, excluding overlapping results. DATA SOURCES: Systematic searches were performed up to August 2023 in PubMed, Embase, and Cochrane Library. We included reviews that compared high-fidelity simulation against other learning strategies. REVIEW METHODS: The risk of bias was assessed for each included systematic review (ROBIS tool) and primary study (RoB 2 or ROBINS-I as appropriate). Random-effect meta-analyses of meta-analyses were performed to estimate the pooled effects of high-fidelity simulation on knowledge and performance. Further random-effect meta-analyses of primary studies were conducted, with overlapping studies excluded (12 %). Subgroup analyses were performed to provide a more comprehensive analysis of the findings. Trim-and-fill analyses were conducted to adjust for potential publication bias. RESULTS: Six systematic reviews were included and encompassed 133 primary studies (2767 and 3231 participants concerning performance and knowledge, respectively). The adjusted pooled effects for knowledge (SMD = 0.877, 95 % CI: 0.182 to 1.572) and performance (SMD = 0.738, 95 % CI: 0.466 to 1.010) closely aligned with those obtained from meta-analyzing the primary studies for knowledge (SMD = 0.980) and performance (SMD = 0.540), both showing high statistical heterogeneity. Traditional lectures represented the more common comparison. The subgroup analysis revealed significant differences in effect sizes across geographic locations, topics, types of control, and how interventions were reported. CONCLUSIONS: The results provide robust evidence supporting the integration of high-fidelity simulation into undergraduate nursing programs to enhance students' knowledge and performance. The high reported heterogeneity may be attributed to variations in study contexts or methodologies. Future research should explore the optimal use of high-fidelity simulation in different educational and cultural contexts.

BACKGROUND: Family and community nurses (FCNs) play a crucial role in delivering primary care to patients within their homes and communities. A key aspect of their role involves various health interventions, which are influenced by their unique competencies, such as health promotion, advanced clinical knowledge, and strong interpersonal skills. However, it is essential to understand which specific health outcomes these interventions impact to better understand the relationship between FCNs' skills and the health results. OBJECTIVE: This study aims to outline the steps we will take to develop a set of core outcomes. These outcomes will be particularly sensitive to the health interventions carried out by FCNs, providing a clearer picture of their practice's impact. METHODS: A Delphi survey will be used for this research, conducted from January to December 2024. The process will involve 5 steps and input from 3 stakeholder categories. These stakeholders will help identify a preliminary list of outcomes that will form the basis of our core outcome set (COS). RESULTS: This guideline will be beneficial for a wide range of stakeholders involved in COS development, including COS developers, trialists, systematic reviewers, journal editors, policy makers, and patient groups. As of January 2024, we have successfully completed the first stage of the study, with the stakeholder group approving the reported outcomes and assigning participant lists for each stakeholder group. CONCLUSIONS: This study will provide a roadmap for identifying the key health outcomes influenced by the interventions of FCNs. The multistakeholder, multiphase approach will ensure a comprehensive and inclusive process. Ultimately, the findings will enhance our understanding of FCNs' impact on health outcomes, leading to more effective primary care strategies and policies.
