Abstract This study presents new ionanofluids (INF) composed of 1-ethyl-3-methylimidazolium acetate ionic liquid (IL) and graphene oxide (GO) nanoparticles which have been assessed for the first time in an experimental flat plate solar thermal collector (FPSC). For this purpose, four types of INFs were synthesized, maintaining a constant concentration of GO nanoparticles dispersed in different base fluids: ionic liquid (IL/GO), a mixture of ionic liquid and water in varying concentrations (IL-water (75–25)%/GO and IL-water (50–50)%/GO), and water (Water/GO). These four INFs were characterized and their thermophysical and physicochemical properties were determined. The results indicated a 37.4% improvement in efficiency and up to a 2.5-fold increase in temperature within the collector when the IL was applied exclusively as the base fluid, compared to water. Furthermore, IL/GO demonstrated excellent stability, showing no signs of deterioration or nanoparticle precipitation two years after preparation and testing. These findings suggest that INFs based on IL and GO nanoparticles significantly enhance the efficiency of FPSC, presenting a promising option for solar energy applications and opening a new research avenue for INFs in the production of domestic hot water.

Palaeoseismological studies play a crucial role in the seismic characterization of regions with slow-moving faults. This is the case in the central Betic Cordillera, a highly populated area for which the record of prehistoric earthquakes is very limited, despite being one of the regions with the greatest seismic hazard in Spain. We present here a palaeoseismological characterization of the Galera Fault, one of the active faults accommodating deformation in the central Betic Cordillera. We excavated and analysed several trenches along the fault trace. We quantitatively correlate the results from these trenches, resulting in a surface rupture history involving seven or eight events (accounting for the epistemic uncertainties) during the last ca. 24 000 years, with recurrence intervals ranging from 1520 to 1720 years. Further analysis of this surface rupture history seems to indicate that the Galera Fault is prone to producing earthquake clusters as we recorded five events in ∼400 years (ca. 1536–1126 BCE) and only two events in the ∼3200 years that followed. Using the fault geometry and palaeoseismological data, we also carried out a seismogenic characterization of the fault. This analysis yielded a maximum expected magnitude of 6.7 ± 0.3 and a recurrence interval of 1857 years. Furthermore, we also present a geodetic rupture scenario for the maximum expected event, involving displacements of up to 0.5 m. Finally, we discuss the possible impact of the deduced palaeoearthquakes on the development of Bronze Age human settlements located in the vicinity of the fault. In addition to their intrinsic value, our results will provide the basis for future seismic-hazard assessments carried out in the central Betic Cordillera.

Abstract Background There is little research investigating the subjective experiences of parenting young children while living in poverty and experiencing financial strain using qualitative methodologies. Therefore, the objective of this study was to employ a qualitative approach to provide a nuanced and balanced view on the topic of parenting young children under financial strain in the Canadian context. Methods We conducted a qualitative study using semi-structured interviews between July and August 2021 in Kingston, Ontario, Canada. Sixteen participants aged 20–39 self-identified as living under financial strain while parenting a child aged 2–5 years. A qualitative inductive thematic analysis was undertaken with a focus on describing the contents of the data. Results Four major themes emerged from the data: experience of being a parent, impact of financial strain on the family unit, impact of financial strain on the children, and impact of financial strain on the parent. Numerous deleterious physical, mental, and material impacts on the family unit and parent were identified, however parent-perceived impacts of financial strain on their children were minimal. Parents described striking levels of resourcefulness and resiliency in providing the necessities for their families, absorbing the most significant impacts of financial strain through the phenomenon of self-sacrifice. Conclusion The impacts of financial strain on families with young children are far reaching. Further research into the impacts of self-sacrifice on parents experiencing financial strain are needed to better understand this issue, and to inform social programming and resources that could help alleviate the deleterious impacts of poverty on parent mental, social, and physical health.

Hematological cancers are among the most common cancers in adults and children. Despite significant improvements in therapies, many patients still succumb to the disease. Therefore, novel therapies are needed. The Wiskott-Aldrich syndrome protein (WASp) family regulates actin assembly in conjunction with the Arp2/3 complex, a ubiquitous nucleation factor. WASp is expressed exclusively in hematopoietic cells and exists in two allosteric conformations: autoinhibited or activated. Here, we describe the development of EG-011, a first-in-class small molecule activator of the WASp auto-inhibited form. EG-011 possesses in vitro and in vivo anti-tumor activity as a single agent in lymphoma, leukemia, and multiple myeloma, including models of secondary resistance to PI3K, BTK, and proteasome inhibitors. The in vitro activity was confirmed in a lymphoma xenograft. Actin polymerization and WASp binding was demonstrated using multiple techniques. Transcriptome analysis highlighted homology with drugs-inducing actin polymerization.

Bacteria are capable of remarkable adaptations to their environment, including undesirable bacterial resistance to antibacterial agents. One of the most serious cases is an infection caused by multidrug-resistant Staphylococcus aureus, which has unfortunately also spread outside hospitals. Therefore, the development of new effective antibacterial agents is extremely important to solve the increasing problem of bacterial resistance. The bacteriolytic enzyme autolysin E (AtlE) is a promising new drug target as it plays a key role in the degradation of peptidoglycan in the bacterial cell wall. Consequently, disruption of function can have an immense impact on bacterial growth and survival. An in silico and in vitro evaluation of iminosugar derivatives as potent inhibitors of S. aureus (AtlE) was performed. Three promising hit compounds (1, 3 and 8) were identified as AtlE binders in the micromolar range as measured by surface plasmon resonance. The most potent compound among the SPR response curve hits was 1, with a KD of 19 μM. The KD value for compound 8 was 88 μM, while compound 3 had a KD value of 410 μM.

Introduction In the assessment of suicidal behavior, recent studies describe the great influence of an environmental component with adverse life events and stressors that can influence ideation and self-harm. Objectives -1. We propose to analyze the reasons for consultation of adolescents between 12 and 16 years old who consult for suicidal ideation/behavior. 2. Estimate the frequency of different socio-family life events. Methods -A retrospective review of emergency consultations in the last 4 months is performed. Sociodemographic data, vital events, reason for consultation and evolution in the following 40 days after the first consultation are collected. Results -Data are collected from 16 adolescents who consult due to suicidal ideation/gesture in a period of 4 months, of which 42% (7) are women and 57% (9) are men. The reasons recorded as stressful life events were: 32% unstructured family environment, 13% death of a close relative, 37% poor parental supervision, 26% end of a romantic relationship, 15% legal problems, 2% sexual or physical abuse, 68 % academic problems, 13% bullying. It was observed that in 63% of the cases they had more than one adverse experience. Conclusions -Different adverse life events frequently precede suicidal ideation and behavior that can be minimized or go unnoticed and undervalued. A meticulous clinical history can clarify some of the reasons that influence the hopelessness and clinical anguish that suicidal patients present. Its early detection provides the opportunity for an early and specialized approach Disclosure of Interest None Declared

Introduction The gut-brain axis establishes the relationships between bacteria, neurotransmitters and psychophysiological responses associated with a neuronal and behavioral correlate in autism and different mental disorders. In recent years, there has been an increase in studies on the implications of the gut microbiota (MI) in children with autism spectrum disorders (ASD). Objectives 1. To study if there is a dysbiosis or alteration of the MI can trigger the appearance of ASD symptoms. It is considered that there is a frequent comorbidity with gastro-intestinal symptoms (GS), pain and sensory reactivity in ASD, and that these are indicators of a possible alteration in the gut-brain axis. Methods In this sense, children with ASD have hypersensitivity to certain visual, olfactory, tactile, etc. stimuli. which makes them be more picky about food and have certain repetitive patterns of behavior, as a consequence they present gastrointestinal symptoms such as constipation and abdominal pain. Sensory reactivity can influence both feeding and sleep patterns in autism. Results Currently, there are measuring instruments for sensory reactivity, pain and gastro-intestinal symptoms. However, there are several limitations of these instruments and especially with sensory reactivity in autism because: (1) the items had not been developed in collaboration with interested parties (pediatricians, neuropsychologists, etc.) and (2) the lack of structural validity analysis. Thus, it appears that most validation studies do not meet the criteria of sufficient psychometric quality according to the COSMIN guidelines. Additionally, there is a lack of consensus around terminology (e.g., sensory overreactivity, hyperreactivity, SOR, etc.) and components relevant to sensory functioning. Conclusions In the present work, preliminary data are presented on new measures to take into account to evaluate sensory reactivity and pain in the population with autism. This is a first step to obtain an index of the gut-brain axis for the ASD population. Keywords: ASD, gut-brain, sensory reactivity, pain Disclosure of Interest None Declared

Introduction Reviewing the histories of patients with childhood and adolescent schizophrenia, on numerous occasions, traumatic factors with great emotional and social impact are observed, such as situations of mistreatment, abuse and emotional deprivation, where help is requested but resources are scarce and the approach is limited without work in network. Objectives 1. Analysis of the consultation pathways in adolescents with severe psychiatric and socio-familial symptoms and the time delay in optimal guidance. 2. Evaluate the services involved. 3. Evaluate the clinical control of treatment with aripiprazole. Methods Retrospective observational analysis, 5 months, of prodromal symptoms of childhood psychosis and help-seeking pathways in a 13-year-old adolescent, as well as a description of the pharmacological approach and professional teams involved. Results A 13-year-old adolescent who went to the emergency room with her mother for ingesting anti-cockroaches with self-inflicted intent. Reviewing his medical history, 4 serious autolytic gestures were detected in the last 2 months. Referred to Mental Health who did not attend. On clinical examination, florid psychotic, with perplexity, self-reference, ideation of harm, language and behavioral disorganization. Auditory and kinesthetic hallucinations. A situation of neglect of the minor and abuse by the parents is detected; the risk had not been previously reported. Oral aripiprazole (up to 15 mg/day) was prescribed with good tolerance and progressive improvement in symptoms. We worked jointly with Social Services, the Juvenile Prosecutor’s Office, Education and the hospital Psychiatry unit. In some of the resources the situation was already evident, the scope of their action was limited and delaying attention for months. Conclusions Based on cases like this, we ask ourselves if psychiatrists are sensitized to the comorbidity of serious mental pathology and the existence of risk situations in minors and if they are oriented toward multiprofessional management. Networking provides us with an early diagnosis, improving the therapeutic approach. Disclosure of Interest None Declared

The pyruvate transporter MPC1 (mitochondrial pyruvate carrier 1) acts as a tumour-suppressor, loss of which correlates with a pro-tumorigenic phenotype and poor survival in several tumour types. In high-grade serous ovarian cancers (HGSOC), patients display copy number loss of MPC1 in around 78% of cases and reduced MPC1 mRNA expression. To explore the metabolic effect of reduced expression, we demonstrate that depleting MPC1 in HGSOC cell lines drives expression of key proline biosynthetic genes; PYCR1, PYCR2 and PYCR3, and biosynthesis of proline. We show that altered proline metabolism underpins cancer cell proliferation, reactive oxygen species (ROS) production, and type I and type VI collagen formation in ovarian cancer cells. Furthermore, exploring The Cancer Genome Atlas, we discovered the PYCR3 isozyme to be highly expressed in a third of HGSOC patients, which was associated with more aggressive disease and diagnosis at a younger age. Taken together, our study highlights that targeting proline metabolism is a potential therapeutic avenue for the treatment of HGSOC.

Abstract Critical care practice is constantly evolving. Pressures for bed availability in publicly funded healthcare systems have led to an increase in patients delayed in their discharge from critical care to the wards. This has resulted in more patients discharged directly home (DDH) from the intensive care unit (ICU). However, few formal pathways for DDH exist. We have performed a retrospective audit of the patients discharged home from our unit in the largest tertiary referral hospital in the Republic of Ireland from 2017 to 2022 to investigate their characteristics and the safety of this practice, given the understandable patient safety concerns raised. Results In total, 84 patients have been DDH from our unit between 2017 and 2022 from a total of 4747 patients. The overall rate of DDH increased year on year, and the vast majority of these patients were initially admitted from the emergency department or following elective major surgery. Most patients had an APACHE score of less than 11 points, and the majority were admitted for less than 3 days, with single organ failure. There was a gender divide, as greater than 60% of the patients admitted were male, with a mean age of 44. Conclusion DDH has been an important tool in improving patient flow through the hospital, avoiding unnecessary de-escalation to the ward for a select group of critical care patients. The re-admission rate in the year post-ICU discharge was very low, showing that DDH has not adversely impacted patient safety.

Treating cell lines with glucocorticoids offers protection against the damage caused by subsequent exposure to selected bacterial pore-forming toxins, and is dependent on the glucocorticoid receptor.

ABSTRACT: Uterine diseases and heat stress (HS) are major challenges for the dairy cow. Heat stress alters host immune resilience, making cows more susceptible to the development of uterine disease. Although HS increases the incidence of uterine disease, the mechanisms by which this occurs are unclear. We hypothesize that evaporative cooling (CL) to alleviate HS in prepartum cows has carry-over effects on postpartum innate immunity. Nulliparous pregnant Holstein heifers were assigned to receive either forced CL that resulted in cool conditions (shade with water soakers and fans; n = 14) or to remain under HS conditions (barn shade only; n = 16) for 60 d prepartum. Postpartum, all cows were housed in a freestall barn equipped with shade, water soakers, and fans. Respiratory rate and rectal temperature during the prepartum period were greater in HS heifers compared with CL heifers, indicative of HS. Although milk production was decreased in HS cows compared with CL cows, the incidence of uterine disease and content of total or pathogenic bacteria in vaginal mucus on d 7 or d 21 postpartum was not affected by treatment. Whole blood was collected on d 21 and subjected to in vitro stimulation with lipopolysaccharide. Lipopolysaccharide-induced accumulation of IL-1β, IL-10, and MIP-1α was greater in blood collected from HS cows compared with CL cows. Our results imply that prepartum HS during late pregnancy has carry-over effects on postpartum innate immunity, which may contribute to the increased incidence of uterine disease observed in cows exposed to prepartum HS.

Spelling ability is a key dimension of orthographic knowledge and a crucial component literacy skill that supports automatic word recognition and fluent reading. There has been substantial research on first language (child) English speakers’ spelling ability, including the effectiveness of instruction interventions for improving spelling knowledge. However, there is relatively little research on spelling in adult learners of English as a second language, and even less examining instructional interventions for improving their spelling. The current study addressed this gap by implementing an adaptation of a phonics-based instructional intervention in a university-based intensive English reading class. Compared to two different control cohorts, the cohort receiving the intervention significantly improved their ability to accurately identify whether an English word was spelled correctly or not. Analyses also considered the influence of a variety of lexical characteristics as well as participants’ L1 writing system. The results demonstrate the efficacy of this intervention in adult L2 English learners and also highlight the importance of considering word characteristics and participants’ language background when examining spelling performance.

Abstract Objective Tracheostomy tube change is a multistep skill that must be performed rapidly and precisely. Despite the critical importance of this skill, there is wide variation in teaching protocols. Methods An innovative operant conditioning teaching methodology was employed and compared to traditional educational techniques. Medical student volunteers at a tertiary care academic institution (Albert Einstein College of Medicine) were recruited and randomly distributed into 2 groups: operant vs traditional (control). Following the educational session, each group was provided with practice time and then asked to perform 10 tracheostomy tube changes. Performance was recorded and scored by blinded raters using deidentified video recordings. Results The operant learning group (OLG) demonstrated greater accuracy in performing a tracheostomy tube change than the traditional demonstration group. Twelve of 13 operant learners performed the skill accurately each time compared to 3 of 13 in the traditional group (P = 0.002). The median lesson time was longer for the OLG (535 seconds) than for the traditional group, (200 seconds P

The t(14;19)(q32;q13) often juxtaposes BCL3 with immunoglobulin heavy chain (IGH) resulting in overexpression of the gene. In contrast to other oncogenic translocations, BCL3 rearrangement (BCL3-R) has been associated with a broad spectrum of lymphoid neoplasms. Here we report an integrative whole-genome sequence, transcriptomic, and DNA methylation analysis of 13 lymphoid neoplasms with BCL3-R. The resolution of the breakpoints at single base-pair revealed that they occur in two clusters at 5’ (n=9) and 3’ (n=4) regions of BCL3 associated with two different biological and clinical entities. Both breakpoints were mediated by aberrant class switch recombination of the IGH locus. However, the 5’ breakpoints (upstream) juxtaposed BCL3 next to an IGH enhancer leading to overexpression of the gene whereas the 3’ breakpoints (downstream) positioned BCL3 outside the influence of the IGH and were not associated with its expression. Upstream BCL3-R tumors had unmutated IGHV, trisomy 12, and mutated genes frequently seen in chronic lymphocytic leukemia (CLL) but had an atypical CLL morphology, immunophenotype, DNA methylome, and expression profile that differ from conventional CLL. In contrast, downstream BCL3-R neoplasms were atypical splenic or nodal marginal zone lymphomas (MZL) with mutated IGHV, complex karyotypes and mutated genes typical of MZL. Two of the latter four tumors transformed to a large B-cell lymphoma. We designed a novel fluorescence in situ hybridization assay that recognizes the two different breakpoints and validated these findings in 17 independent tumors. Overall, upstream or downstream breakpoints of BCL3-R are mainly associated with two subtypes of lymphoid neoplasms with different (epi)genomic, expression, and clinicopathological features resembling atypical CLL and MZL, respectively.

Abstract Nowadays, exome sequencing is a robust and cost-efficient genetic diagnostic tool already implemented in many clinical laboratories. Despite it has undoubtedly improved our diagnostic capacity and has allowed the discovery of many new Mendelian-disease genes, it only provides a molecular diagnosis in up to 25–30% of cases. Here, we comprehensively evaluate the results of a large sample set of 4974 clinical exomes performed in our laboratory over a period of 5 years, showing a global diagnostic rate of 24.62% (1391/4974). For the evaluation we establish different groups of diseases and demonstrate how the diagnostic rate is not only dependent on the analyzed group of diseases (43.12% in ophthalmological cases vs 16.61% in neurological cases) but on the specific disorder (47.49% in retinal dystrophies vs 24.02% in optic atrophy; 18.88% in neuropathies/paraparesias vs 11.43% in dementias). We also detail the most frequent mutated genes within each group of disorders and discuss, on our experience, further investigations and directions needed for the benefit of patients.

Abstract Background Bacterial infection of the uterus in postpartum dairy cows limits ovarian follicle growth, reduces blood estradiol concentrations, and leads to accumulation of bacterial lipopolysaccharide (LPS) in ovarian follicular fluid. Although treating granulosa cells with LPS in vitro decreases the expression of the estradiol synthesis enzyme CYP19A1 and reduces estradiol secretion, the molecular mechanisms are unclear. The transcription factor CCAAT enhancer binding protein beta (CEBPβ) not only facilitates the transcription of LPS regulated cytokines, but also binds to the promoter region of CYP19A1 in humans, mice, and buffalo. We hypothesized that LPS alters CEBPβ signaling to reduce CYP19A1 expression, resulting in decreased estradiol secretion. Methods Bovine granulosa cells were isolated from small/medium or large follicles and treated with LPS in the presence of FSH and androstenedione for up to 24 h. Results Treatment with LPS increased CXCL8 and IL6 gene expression and reduced estradiol secretion in granulosa cells from both small/medium and large follicles. However, LPS only reduced CYP19A1 expression in granulosa cells from large follicles. Treatment with LPS increased CEBPB expression and reduced CEBPβ nuclear localization in granulosa cells from small/medium follicles, but not granulosa cells from large follicles. Conclusions Although LPS reduces estradiol synthesis in bovine granulosa cells, the effects of LPS on CYP19A1 and CEBPβ are dependent on follicle size.

NOTCH mutations are frequent in B cell malignancies. Here the authors use retroviral transduction of primary malignant B cells from Chronic Lymphocytic Leukemia (CLL) and Mantle Cell Lymphoma (MCL) patients to show that NOTCH1/2-mutations facilitate mechanism of immune escape.

Abstract Background Existing studies of patient-reported outcomes (PRO) following total knee arthroplasty (TKA) based on fixation methods (cemented vs cementless) are limited to single centers with small sample sizes. Using multicentered data,, we compared baseline and early post-operative global and condition-specific PROs between patients undergoing cemented versus cementless TKA. Methods With PROs prospectively collected through Comparative Effectiveness Pulmonary Embolism Prevention After Hip and Knee Replacement (PEPPER) trial (ClinicalTrials.gov: NCT02810704), we examined pre- and post-operative (1, 3, and 6-months) outcomes in 5,961 patients undergoing primary TKA enrolled by 28 medical centers between December 2016 and August 2021. Outcomes included the short-form of the Knee Injury and Osteoarthritis Outcome Score (KOOS-Jr.), the Patient-Reported Outcomes Measurement Information System Physical Health (PROMIS-PH), and the Numeric Pain Rating Scale (NPRS). To minimize selection bias, we performed a 1-to-1 propensity score matched analysis to assess relative pre- to post-operative change in outcomes within and between cemented and cementless TKA groups. Results With greater than 90% follow-up, significant pre to- post-operative improvements were observed in both groups. At 6 months, the cemented TKA group achieved a 3.3 point (55% of the Minimum Clinically Important Difference) greater improvement in the mean KOOS-Jr. (95%CI: 0.36, 6.30; P = 0.028) than did the cementless group with no significant between-group differences in PROMIS-PH and NPRS. Conclusions In a large cohort of primary TKAs, patients with cemented fixation reported early incremental benefit in KOOS-Jr. over those with cementless TKA. Future studies are warranted to capture longer follow-up of PROs.

There is still a long way ahead regarding the COVID-19 pandemic, since emerging waves remain a daunting challenge to the healthcare system. For this reason, the development of new preventive tools and therapeutic strategies to deal with the disease have been necessary, among which serological assays have played a key role in the control of COVID-19 outbreaks and vaccine development. Here, we have developed and evaluated an immunoassay capable of simultaneously detecting multiple IgG antibodies against different SARS-CoV-2 antigens through the use of Bio-PlexTM technology. Additionally, we have analyzed the antibody response in COVID-19 patients with different clinical profiles in Cadiz, Spain. The multiplex immunoassay presented is a high-throughput and robust immune response monitoring tool capable of concurrently detecting anti-S1, anti-NC and anti-RBD IgG antibodies in serum with a very high sensitivity (94.34–97.96%) and specificity (91.84–100%). Therefore, the immunoassay proposed herein may be a useful monitoring tool for individual humoral immunity against SARS-CoV-2, as well as for epidemiological surveillance. In addition, we show the values of antibodies against multiple SARS-CoV-2 antigens and their correlation with the different clinical profiles of unvaccinated COVID-19 patients in Cadiz, Spain, during the first and second waves of the pandemic.

Summary: Antibiotic resistance is reaching alarming levels, demanding for the discovery and development of antibiotics with novel chemistry and mechanisms of action. The recently discovered antibiotic cacaoidin combines the characteristic lanthionine residue of lanthipeptides and the linaridin-specific N-terminal dimethylation in an unprecedented N-dimethyl lanthionine ring, being therefore designated as the first class V lanthipeptide (lanthidin). Further notable features include the high D-amino acid content and a unique disaccharide substitution attached to the tyrosine residue. Cacaoidin shows antimicrobial activity against gram-positive pathogens and was shown to interfere with peptidoglycan biosynthesis. Initial investigations indicated an interaction with the peptidoglycan precursor lipid IIPGN as described for several lanthipeptides. Using a combination of biochemical and molecular interaction studies we provide evidence that cacaoidin is the first natural product demonstrated to exhibit a dual mode of action combining binding to lipid IIPGN and direct inhibition of cell wall transglycosylases.

Introduction In schizoaffective disorder, treatment with atypical antipsychotics is a first-line treatment option associated with treatment with mood stabilizers. One of the associated adverse effects is weight gain, which is sometimes associated with a deterioration of self-image and greater psychosocial impact. Objectives 1. To assess the personal perception and psychosocial adjustment in patients with affective psichotic disorder onset of symptoms in adolescence in current treatment with oral or IM aripiprazole. 2. To determine if there is variation in self-perception in patients with oral treatment compared to patients with long-term injectable treatment Methods Patients with affective psichotic disorder onset in adolescence come to consultation. Retrospective data collection: 9 months. Cross-sectional assessment with E-PICA scale. SPSS21.0. Results 33 patients, 60% women (mean 38.6 years) and 40% men (40.46 years). Men consulted for psychiatric symptoms earlier and their diagnosis is earlier than in women (men: onset 16.8 years, ASD diagnosis 27.15; women: symptoms onset 20.5 years, diagnosis 37.1 years). The use of ILD aripiprazole is observed in 54%, with a similar proportion in both sexes (men 53%, women 55%). In patients with oral aripiprazole, scores were obtained: mild psychosocial impact in 18%, all of them women; moderate impact 18% and severe impact in 9% of cases. While the results with ILD treatment: mild impact in 30% and moderate impact in 24% of cases, not observing severity scores in aripiprazole ILD. Conclusions We observed a better body perception and self-esteem in women diagnosed with schizoaffective disorder and with long-term injectable aripiprazole treatment, assessing the psychosocial impact as mild. In men, the impact is greater, being observed more frequently in men with oral treatment. Continuity of follow-up and future studies will be necessary to determine other associated factors, as well as comparison with the use of other treatments. Disclosure of Interest None Declared

Introduction Serious mental illness in adolescence that not only has a significant impact on the patient but also on other contexts such as their family. Caregivers assume almost all of the care. This responsibility exposes caregivers to intense overload with negative consequences. Objectives To evaluate and quantify the overload of the primary caregiver in children and adolescents with severe mental disorders. Methods A prospective study was designed using structured interviews in caregivers of patients between 11 and 18 years of age with severe mental disorders and substance use who were evaluated in the psychiatric emergency service for 2 months. The Zarit Caregiver Burden Scale was used for quantitative assessment. Diagnosis, main caregiver, socio-health resources were recorded. Results Of a total of 35 patients with serious mental illness between 11 and 16 years of age, the following was observed: intense caregiver burden in 42.2% of cases, moderate in 21%. Being the main caregiver the mother. 27.5% had adequate use of socio-health resources, while 42.7% had not requested them. The greatest need detected was economic and rehabilitation. Conclusions Serious mental disorder present since adolescence leads families to significant destabilization of the family nucleus and comorbidity of psychiatric disorders in caregivers. Good orientation and evaluation of individual cases are necessary to guide families about the resources available in the social and health network, thus avoiding a high overload of caregivers and improving the quality of life of families.

Introduction Chronic back pain is one of the leading causes of disability and treatment is often ineffective. Approximately 85% of cases are primary, for which the peripheral etiology cannot be identified, and maintenance factors include fear, avoidance, and beliefs that pain indicates injury.Studies suggest that an excessively negative orientation towards pain (pain catastrophism) and fear of movement/(re)injury (kinesiophobia) are important in the aetiology of chronic low back pain and associated disability. Objectives The aim is to identify the psychopatological profile (including levels of movement phobia and catastrophic thinking) in patients with chronic low back pain who participate in a multidisciplinary group Comprehensive Care Program for Patients with Chronic Pain (PAINDOC) in the Pain Unit of the Hospital Clínic i Provincial de Barcelona. Methods A cross-sectional descriptive study of 75 patients aged between 28 and 68 years who participate in the treatment is carried out. A clinical interview was carried out, anxiety and depression symptoms were assessed with thHospital Anxiety and Depression Scale (HADS), Kinesiophobia was evaluated with the Tampa Scale Kinesiophobia (TSK-11SV) and catastrophism with the Pain Catastrophizing Scale (PCS). Results The results show that the patients presented a high level of catastrophic thinking, especially in the subgroup of women with a longer duration of pain.Movement phobia was observed in 27% of patients, and correlated with feelings of depression and anxiety. Conclusions Catastrophism is a multidimensional psychological construct that encompasses elements such as rumination, magnification, and incapacity.Catastrophic thinking in relation to pain is a risk factor for chronic pain. Kinesiophobia is based on the fear avoidance model and perpetuates a cycle of heightened fear of pain, disability, and depression. These constructs can be very useful to evaluate in patients to reduce the intensity of pain, the associated emotional suffering and reduce the probability that the pain will become chronic.

Introduction Clinical case description. A 44-year-old male, with paranoid schizophrenia, polydrug addict and IVDU since he was 14 years old. Live alone. He is brought by the Local Police for heteroaggressiveness when he was arrested for trespassing and resisting authority. He has presented 14 hospital admissions and therapeutic communities for detoxification since 2000. Objectives 1. To analyze the causes of abandonment of treatment Methods 1. Complete medical history 2. Blood test with hormone profile 3. PRAEQ Questionnaire Absence of child psychopathology until the age of 6, at which time his parents separate and he becomes introverted, with solitary activities and distractions. On examination, the patient is restless. Psychotic contact. Delusional speech centered on ill-structured ideas of harm, persecution and grandiose, being difficult to explore due to lack of collaboration on the part of the patient, who only accepts treatment with aripiprazole 5 mg due to sexual dysfunction with the rest of the treatments. Results During his admission, he has evolved from a very unstructured delusional theme and social isolation, with lax and tangential speech and refusal to take any treatment except aripiprazole, towards a cooperative, trusting attitude, with attenuation of his delusional ideation, with appropriate, organized and releasable. Treatment with IM aripiprazole is agreed upon for discharge. Clinical judgement: Paranoid schizophrenia (F20.0) Conclusions With this case, we intend to remember that antipsychotics affect different spheres of the patient’s life that can hinder adherence to treatment, and that we often do not take into account. In this specific case, Abilify Maintena is useful because it does not cause sexual dysfunction, which facilitates treatment adherence and greater patient involvement, which gives us greater opportunities for social integration.

Introduction Schizophrenia is a chronic disease that deteriorates the functionality of patients, especially when raising a family and caring for children. We are interested in analyzing the characteristics of mothers and fathers diagnosed with schizophrenia and their degree of global activity when switching from oral treatments to injectable treatments. Objectives 1 To evaluate the quality of life and functional level of mothers with schizophrenia treated with quarterly paliperidone palmitate. 2. To compare the quality of life and functional level when switching from oral treatment to long-acting injectables. Methods Participants were 3 mothers and 3 fathers, 33-40 years old, with a diagnosis of schizophrenia in monotherapy who changed treatment with monthly paliperidone palmitate to quarterly paliperidone palmitate LD IM (525 mg/every 12 weeks). Retrospective data collection. QLS quality of life scale. Results Six patients were included, caregivers of 1 child (80%), 2 children (20%) who met the inclusion criteria and completed the questionnaires. After its application and correction by means of non-parametric tests (N

Abstract Current somatic mutation callers are biased against repetitive regions, preventing the identification of potential driver alterations in these loci. We developed a mutation caller for repetitive regions, and applied it to study repetitive non protein-coding genes in more than 2200 whole-genome cases. We identified a recurrent mutation at position c.28 in the gene encoding the snRNA U2. This mutation is present in B-cell derived tumors, as well as in prostate and pancreatic cancer, suggesting U2 c.28 constitutes a driver candidate associated with worse prognosis. We showed that the GRCh37 reference genome is incomplete, lacking the U2 cluster in chromosome 17, preventing the identification of mutations in this gene. Furthermore, the 5′-flanking region of WDR74, previously described as frequently mutated in cancer, constitutes a functional copy of U2. These data reinforce the relevance of non-coding mutations in cancer, and highlight current challenges of cancer genomic research in characterizing mutations affecting repetitive genes.
