The plastic injection moulding industry is a constantly developing industrial field. This industrial process requires the manufacturing of metal moulds using complex heating and cooling systems. The purpose of this research is to optimize both the plastic injection moulding process and the mould manufacturing process itself by combining practices in this industry with current additive manufacturing technologies, specifically Wire Arc Additive Manufacturing (WAAM) technology. A mould punch was manufactured by using both WAAM technology, whose internal cooling system has been designed under the concept of Conformal Cooling, and conventional cooling channel designs and manufacturing techniques in order to carry out a comparative analysis. Theoretical results obtained by CAE methods showed an improvement in heat extraction in the WAAM mould. In addition, the WAAM mould was able to achieve better temperature homogeneity in the final part, minimizing deformations in the final part after extraction. Finally, the WAAM manufacturing process was proven to be more efficient in terms of material consumption than the conventional mould, reducing the buy-to-fly ratio of the part by 5.11.

Background: To implement recovery-oriented practice, it is important to have instruments capable of evaluating such practice. A number of different questionnaires have been developed in recent years which measure recovery orientation in mental health services. Objective: To identify and analyze patient-reported experience measures (PREMs) reported in the literature that are related to recovery-oriented practice in mental health services. Methodology: This study followed the Joanna Briggs Institute methodology for scoping reviews. Searches were carried out in the Web of Science, CINAHL, Medline (via Pubmed), and SCOPUS databases and in grey literature repositories (Google Scholar, Opengrey, Dart-Europe, Teseo). Papers on recovery services for adults suffering from mental disorders (MDs) were included. Those focusing on addiction and intellectual disability care services were excluded. Results: Sixteen papers met the inclusion criteria. The selected PREMs mainly identified recovery-oriented systems, treatment, community integration and support as the dimensions addressed most frequently in questionnaires. The average number of items included in the questionnaires was found to be 54. With regard to psychometric properties, 62% of the papers evaluated reliability (internal consistency) and 56% provided some kind of evidence of validity. Conclusions: This review aims to give an overview of the existing instruments in the literature and to highlight the characteristics of each one of them. Several different PREMs exist which evaluate recovery-oriented practice. No instrument currently exists which could be described as a benchmark tool, but there are quite a few with good psychometric properties capable of producing data that are useful when evaluating clinical services.

Acute lymphoblastic leukemia (ALL) is a hematopoietic disorder that mainly affects the child population, and it is characterized by the presence of lymphoid progenitor or precursor cells with different genetic alterations. The origin of this disease is controversial, since some authors assumed that leukemic transformation occurs in a lymphoid progenitor, and there is also evidence that suggests the existence of leukemic initiating cells (LIC). PTL, DMAPT, and PU-H71 are agents that have been shown to eliminate bulk and stem cells from myeloid leukemias, but this effect has not been analyzed in lymphoblastic leukemias. In this study, we evaluated the effect of these compounds in different populations from pediatric B-ALL. For this, bone marrow samples from pediatric patients without treatment were obtained and cultured in the presence or absence of PTL, DMAPT, and PU-H71. The viability and apoptosis index were analyzed by flow cytometry in different hematopoietic subpopulations. These observations indicate that PTL and DMAPT are able to reduce B-ALL cells with a minimum effect in normal hematopoietic and non-hematopoietic cells. In contrast, PU-H71 was able to reduce the leukemic population and had a minimal effect in normal cells. These results present evidence that PTL and DMAPT are able to abrogate in vitro different populations of B-ALL and could represent a possibility of treatment, as well as prevent disease progression or relapse.

This paper addresses the biomechanical requirements and design of a neck dummy for assessing neck injury risks. The need for an accurate biomechanical representation of the human neck in crash tests is highlighted, emphasizing the importance of replicating the neck's response to impacts. Existing neck dummies are reviewed to assess their similarity to human neck biomechanics, revealing several limitations. To address these gaps, a novel prototype is proposed to mimic the joint between two vertebrae using elastic elements to replicate the behavior of the intervertebral disc. The performance of the neck dummy is evaluated through experimental testing, using IMU and force sensors to monitor its response to perturbations from impacts. The reported results demonstrate that the prototype effectively simulates the intervertebral movement, offering an approach for more accurate injury assessments in crash testing. Concluding remarks suggest the potential of this design to improve the reliability of neck injury assessments in automotive safety research.

Direct-acting antivirals (DAA) are effective in patients with hepatitis C virus (HCV) infection, but there is little information about real-world effectiveness in people living with human immunodeficiency virus (PLH). The aim of this study was to determinate the effectiveness of DAA to achieve sustained virologic response at week 12 post-treatment (SVR12) in PLH with HCV coinfection and in people with HCV-monoinfection. We conducted a prospective cohort. The full analysis set (FAS) included all subjects enrolled in the study; the modified analysis set (MAS) excluded cases with missing data to evaluate SVR12. A total of 278 people were included, 130 (46.7%) with HCV/HIV-coinfection and 148 (53.2%) with HCV-monoinfection. In the HCV/HIV-coinfection group, 82 (63%) received GLE/PIB for 8 weeks, 45 (34.6%) received SOF/VEL for 12 weeks, and 3 (2.3%) were treated with SOF/VEL + RBV for 12 weeks. In the HCV-monoinfection group, 62 (41.8%) received GLE/PIB for 8 weeks, 28 (18.9%) received SOF/VEL for 12 weeks, and 58 (39.1%) participants were treated with SOF/VEL + RBV for 12 weeks. In the FAS analysis, SVR12 was 81.6% in the HCV/HIV-coinfection group and 86.4% in the HCV-monoinfection group (

Many gender differences in mental and physical health, along with accompanying social needs have been reported by those suffering with schizophrenia. The goal of this review is to explore the literature on migrant and culturally diverse women suffering with schizophrenia to develop and implement effective strategies in specialized clinics. In general, we found higher rates of mental health symptoms among migrant and refugee women when compared to men. Several factors contribute to this vulnerability, suggesting that women may experience more pre- and post-migration-related trauma. In clinical populations, migrant status, region of origin, age at the time of migration, migration with family or alone, and migration to join family determine the risk of schizophrenia and the clinical course of the illness. Refugee migrant women have a higher risk of schizophrenia than non-refugee migrants and native-born populations. Migration is associated with poor access to mental health services; low social support, lack of awareness of services, and language barriers may mediate this association. These findings call for specific assessments on migrant women, interventions (e.g., focus groups), and improvement in current programs. In our clinics, we have recently incorporated assessment and intervention strategies that may be effective in our programming.

Microplastics (MPs) are omnipresent particles that receive special attention because of their persistent nature and their potential impact on human disease and on the environment. Most MPs are generated by the degradation of larger plastic items such as clothing, car tires, and discarded plastic materials. In indoor environments, where human beings spend most of their time, aerial MP levels are higher, and the majority are fibers produced from textiles. Airborne MPs indoors are a greater potential danger to humans than MPs ingested in food and drink. Fragments small enough to remain substantially suspended in the air column, the small airborne microparticles that are measured as PM10 and PM2.5, become available for assimilation by human beings through respiration, potentially producing various health problems. Larger MPs act by ingestion and skin contact. MPs can carry microorganisms and micropollutants adsorbed to their surfaces, facilitating their uptake and survival within the human body. Indoor airborne MPs thus represent emerging pollutants of fast-growing concern that are especially important as potential invaders of the human respiratory system, reaching the alveoli of the lungs and finally entering the circulatory system and other tissues. Since this direct human exposure to MP contamination via indoor air is so important, we discuss in this article the ways in which MP concentration and dispersal in indoor air can be affected by air turbulence that is induced by anthropogenic objects such as air conditioners, filters, and purifiers. Much evidence is equivocal and further research is necessary.
