RESUMO

The widespread Pseudomonas genus comprises a collection of related species with remarkable abilities to degrade plastics and polluted wastes and to produce a broad set of valuable compounds, ranging from bulk chemicals to pharmaceuticals. Pseudomonas possess characteristics of tolerance and stress resistance making them valuable hosts for industrial and environmental biotechnology. However, efficient and high-throughput genetic engineering tools have limited metabolic engineering efforts and applications. To improve their genome editing capabilities, we first employed a computational biology workflow to generate a genus-specific library of potential single-stranded DNA-annealing proteins (SSAPs). Assessment of the library was performed in different Pseudomonas using a high-throughput pooled recombinase screen followed by Oxford Nanopore NGS analysis. Among different active variants with variable levels of allelic replacement frequency (ARF), efficient SSAPs were found and characterized for mediating recombineering in the four tested species. New variants yielded higher ARFs than existing ones in Pseudomonas putida and Pseudomonas aeruginosa, and expanded the field of recombineering in Pseudomonas taiwanensisand Pseudomonas fluorescens. These findings will enhance the mutagenesis capabilities of these members of the Pseudomonas genus, increasing the possibilities for biotransformation and enhancing their potential for synthetic biology applications. .

RESUMO

PURPOSE: Facilitated subcutaneous immunoglobulin (fSCIG; immune globulin infusion 10% [human] with recombinant human hyaluronidase [rHuPH20]) permits high-volume subcutaneous immunoglobulin (SCIG) infusion, shorter infusion times and reduced dosing frequency relative to conventional SCIG. It is initiated by gradually increasing infusion volumes over time (dose ramp-up) to achieve target dose level (TDL). Whether ramp-up strategies have tolerability or safety advantages over direct initiation at full TDL has not been evaluated clinically. METHODS: This phase 1 open-label study assessed tolerability and safety of fSCIG 10% with accelerated or no ramp-up compared with conventional ramp-up in healthy adults (NCT04578535). Participants were assigned to one of the three ramp-up arms to achieve TDLs of 0.4 or 1.0 g/kg/infusion. The primary endpoint was the proportion of infusions completed without interruption or infusion rate reduction owing to treatment-emergent adverse events (TEAEs). Safety was assessed as a secondary endpoint. RESULTS: Of 51 participants enrolled, 50 (98.0%) tolerated all fSCIG 10% infusions initiated (n = 174). Infusion rate was reduced in one participant owing to headache in the 0.4 g/kg/infusion conventional ramp-up arm. Study discontinuations were higher in the no ramp-up arm (70%) versus the conventional (0%) and accelerated (22%) arms at the 1.0 g/kg/infusion TDL. Safety outcomes did not substantially differ between treatment arms. CONCLUSION: The favorable tolerability and safety profiles of fSCIG 10% in healthy participants support initiating treatment with fSCIG 10% with accelerated ramp-up at TDLs up to 1.0 g/kg. Data support no ramp-up at TDLs close to 0.4 g/kg but additional data are needed for higher doses.

RESUMO

The Interpersonal Theory of Suicide (IPTS) has received support for its role in understanding suicidal thoughts and behaviors. However, few longitudinal studies have focused on testing this theory in university students. The present study aimed to confirm the theoretical model of the IPTS in a sample of 225 Spanish university students, using path analysis in a longitudinal study. We assessed thwarted belongingness and perceived burdensomeness at T1 and hopelessness and suicidal ideation at T2, 12-14 weeks later. Moreover, we assessed suicidal ideation weekly for 14 weeks. Path analyses confirmed the Interpersonal Theory of Suicide model, with thwarted belongingness and perceived burdensomeness as direct and indirect predictors of suicidal ideation through hopelessness. Providers of guidance and clinical services in university settings should be trained to identify perceived burdensomeness, social belongingness, hopelessness, and suicidal ideation when screening for suicide prevention.

RESUMO

Secondary metabolites, bioactive compounds produced by living organisms, can unveil symbiotic relationships in nature. In this study, soilborne entomopathogenic nematodes associated with symbiotic bacteria (Xenorhabdus stockiae and Photorhabdus luminescens) were extracted from solvent supernatant containing secondary metabolites, demonstrating significant inhibitory effects against E. coli, S. aureus, B. subtilus, P. mirabilis, E. faecalis, and P. stutzeri. The characterization of these secondary metabolites by Fourier transforms infrared spectroscopy revealed amine groups of proteins, hydroxyl and carboxyl groups of polyphenols, hydroxyl groups of polysaccharides, and carboxyl groups of organic acids. Furthermore, the obtained crude extracts were analyzed by high-performance liquid chromatography for the basic identification of potential bioactive peptides. Gas chromatography-mass spectrometry analysis of ethyl acetate extracts from Xenorhabdus stockiae identified major compounds including nonanoic acid derivatives, proline, paromycin, octodecanal derivatives, trioxa-5-aza-1-silabicyclo, 4-octadecenal, methyl ester, oleic acid, and 1,2-benzenedicarboxylicacid. Additional extraction from Photorhabdus luminescens yielded functional compounds such as indole-3-acetic acid, phthalic acid, 1-tetradecanol, nemorosonol, 1-eicosanol, and unsaturated fatty acids. These findings support the potential development of novel natural antimicrobial agents for future pathogen suppression.

RESUMO

BACKGROUND: Atherosclerotic cardiovascular disease is the main cause of mortality worldwide and is strongly influenced by circulating low-density lipoprotein (LDL) cholesterol levels. Only a few genes causally related to plasma LDL cholesterol levels have been identified so far, and only 1 gene, ANGPTL3, has been causally related to combined hypocholesterolemia. Here, our aim was to elucidate the genetic origin of an unexplained combined hypocholesterolemia inherited in 4 generations of a French family. METHODS: Using next-generation sequencing, we identified a novel dominant rare variant in the LIPC gene, encoding for hepatic lipase, which cosegregates with the phenotype. We characterized the impact of this LIPC-E97G variant on circulating lipid and lipoprotein levels in family members using nuclear magnetic resonance-based lipoprotein profiling and lipidomics. To uncover the mechanisms underlying the combined hypocholesterolemia, we used protein homology modeling, measured triglyceride lipase and phospholipase activities in cell culture, and studied the phenotype of APOE*3.Leiden.CETP mice after LIPC-E97G overexpression. RESULTS: Family members carrying the LIPC-E97G variant had very low circulating levels of LDL cholesterol and high-density lipoprotein cholesterol, LDL particle numbers, and phospholipids. The lysophospholipids/phospholipids ratio was increased in plasma of LIPC-E97G carriers, suggestive of an increased lipolytic activity on phospholipids. In vitro and in vivo studies confirmed that the LIPC-E97G variant specifically increases the phospholipase activity of hepatic lipase through modification of an evolutionarily conserved motif that determines substrate access to the hepatic lipase catalytic site. Mice overexpressing human LIPC-E97G recapitulated the combined hypocholesterolemic phenotype of the family and demonstrated that the increased phospholipase activity promotes catabolism of triglyceride-rich lipoproteins by different extrahepatic tissues but not the liver. CONCLUSIONS: We identified and characterized a novel rare variant in the LIPC gene in a family who presents with dominant familial combined hypocholesterolemia. This gain-of-function variant makes LIPC the second identified gene, after ANGPTL3, causally involved in familial combined hypocholesterolemia. Our mechanistic data highlight the critical role of hepatic lipase phospholipase activity in LDL cholesterol homeostasis and suggest a new LDL clearance mechanism.

RESUMO

ABSTRACT: More research on the medium- and long-term effects of childhood exposure to war, including orphanhood, is needed. We compared 50 orphans 1 who lost their father during the war in Bosnia and Herzegovina (1992-1995) and 50 age- and sex-matched adolescents from two-parent families during 2011-2012 in terms of sociodemographic characteristics, behavioral/emotional problems, depression, resilience, maternal mental health, and perceived social support. The two groups differed on sociodemographic factors, that is, number of children, family composition, income, school grades, and refugeehood. Paternal war orphans did not differ in terms of adolescent mental health and resilience from their nonorphaned peers, controlling for sociodemographic variables. The mothers of orphans had comparably more posttraumatic psychopathology. As for perceived resources for social support, orphans identified those comparably more often among distant relatives and in the community, that is, religious officials and mental health professionals, and less often among siblings, paternal grandparents, paternal and maternal uncles/aunts, school friends and teachers. Our findings suggest that contextual factors may play an important role in orphans' postwar mental health.

RESUMO

Currently, the process of evaluating suicide is highly subjective, which limits the efficacy and accuracy of prevention efforts. Artificial intelligence (AI) has emerged as a mean of investigating large datasets to identify patterns within 'big data' that can determine the factors on suicide outcomes. Here, we used AI tools to extract the topic from (press and social) media texts. However, news media articles lack of suicide tags. Using tweets with hashtags related to suicide, we trained a neuronal model that identifies if a given text has a suicide-related topic. Our results suggest a high level of impact of suicide cases in the media, and an intrinsic thematic relationship of suicide news. These results pave the way to build more interpretable suicide data from the media, which may help to better track, understand its origin, and improve prevention strategies.

RESUMO

BACKGROUND: Suicide is a major global public health issue that is becoming increasingly common despite preventive efforts. Though current methods for predicting suicide risk are not sufficiently accurate, technological advances provide invaluable tools with which we may evolve toward a personalized, predictive approach. OBJECTIVE: We aim to predict the short-term (1-week) risk of suicide by identifying changes in behavioral patterns characterized through real-time smartphone monitoring in a cohort of patients with suicidal ideation. METHODS: We recruited 225 patients between February 2018 and March 2020 with a history of suicidal thoughts and behavior as part of the multicenter SmartCrisis study. Throughout 6 months of follow-up, we collected information on the risk of suicide or mental health crises. All participants underwent voluntary passive monitoring using data generated by their own smartphones, including distance walked and steps taken, time spent at home, and app usage. The algorithm constructs daily activity profiles for each patient according to these data and detects changes in the distribution of these profiles over time. Such changes are considered critical periods, and their relationship with suicide-risk events was tested. RESULTS: During follow-up, 18 (8%) participants attempted suicide, and 14 (6.2%) presented to the emergency department for psychiatric care. The behavioral changes identified by the algorithm predicted suicide risk in a time frame of 1 week with an area under the curve of 0.78, indicating good accuracy. CONCLUSIONS: We describe an innovative method to identify mental health crises based on passively collected information from patients' smartphones. This technology could be applied to homogeneous groups of patients to identify different types of crises.

RESUMO

There might be differential characteristics between those who have attempted suicide once in their lifetime (single attempters) and those who have attempted suicide two or more times (multiple attempters). We aimed to identify the factors that differentiate single and multiple attempters in child and adolescents. This study was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, and the review protocol was registered in PROSPERO. We conducted a systematic literature search in three databases to identify original studies exploring the characteristics of single attempters vs. multiple attempters among adolescents. We considered a wide range for the definition of adolescent, following most recent recommendations: 10-24 years. We carried out a meta-analysis. Fourteen studies were included in the systematic review and 13 in the meta-analysis with a total sample of with a total of 4286 participants. The factors statistically significantly associated with being a multiple attempter in the meta-analysis were: anxiety disorders, depression severity, alcohol abuse, substance abuse, aggressiveness, and hopelessness. Multiple attempters have a more severe clinical profile, with greater severity of symptoms. Knowledge of the risk factors associated with being a multiple attempter could help us to predict which patients are more likely to reattempt suicide and need further monitoring and a tailored treatment. Prevention programs tailored for the adolescent population, along with identification of early risk factors, could help to prevent suicidal behavior among this vulnerable population.

RESUMO

Mental disorders in children and adolescents may follow different trajectories, such as remission, change of diagnosis, or addition of two or more comorbid diagnoses, showing a heterotypic pattern. This study aims to describe the main diagnostic trajectories across a broad range of mental disorder diagnostic categories, from childhood to adolescence and from adolescence to young adulthood in a clinical population. A prospective study was conducted among a clinical sample of children and adolescents who were aged 3-17 years at the face-to-face baseline interview. Electronic health records of these participants were reviewed 10 years later. The diagnostic stability over time was examined using the kappa coefficient, and factors associated with stability were explored using simple logistic regression. The study included a sample of 691 participants. The kappa coefficient for diagnostic stability across all diagnoses was 0.574 for the transition from childhood to adulthood, 0.614 from childhood to adolescence, and 0.733 from adolescence to adulthood. Neurodevelopmental diagnoses had the highest stability. Factors associated with higher diagnostic stability included family history of mental disorders, receiving psychopharmacological treatment, and symptom severity at baseline. We found a variable diagnostic stability across different diagnoses and age categories. The different life transitions represent complex periods that should not be overlooked from a clinical standpoint. An appropriate transition from child and adolescent mental health services to adult mental health services may have a positive impact on children and adolescents with mental disorders.

RESUMO

Synthetic biologists design and engineer organisms for a better and more sustainable future. While the manifold prospects are encouraging, concerns about the uncertain risks of genome editing affect public opinion as well as local regulations. As a consequence, biosafety and associated concepts, such as the Safe-by-design framework and genetic safeguard technologies, have gained notoriety and occupy a central position in the conversation about genetically modified organisms. Yet, as regulatory interest and academic research in genetic safeguard technologies advance, the implementation in industrial biotechnology, a sector that is already employing engineered microorganisms, lags behind. The main goal of this work is to explore the utilization of genetic safeguard technologies for designing biosafety in industrial biotechnology. Based on our results, we posit that biosafety is a case of a changing value, by means of further specification of how to realize biosafety. Our investigation is inspired by the Value Sensitive Design framework, to investigate scientific and technological choices in their appropriate social context. Our findings discuss stakeholder norms for biosafety, reasonings about genetic safeguards, and how these impact the practice of designing for biosafety. We show that tensions between stakeholders occur at the level of norms, and that prior stakeholder alignment is crucial for value specification to happen in practice. Finally, we elaborate in different reasonings about genetic safeguards for biosafety and conclude that, in absence of a common multi-stakeholder effort, the differences in informal biosafety norms and the disparity in biosafety thinking could end up leading to design requirements for compliance instead of for safety.

RESUMO

There is growing concern that the social and physical distancing measures implemented in response to the Covid-19 pandemic may negatively impact health in other areas, via both decreased physical activity and increased social isolation. Here, we investigated whether increased engagement with digital social tools may help mitigate effects of enforced isolation on physical activity and mood, in a naturalistic study of at-risk individuals. Passively sensed smartphone app use and actigraphy data were collected from a group of psychiatric outpatients before and during imposition of strict Covid-19 lockdown measures. Data were analysed using Gaussian graphical models: a form of network analysis which gives insight into the predictive relationships between measures across timepoints. Within-individuals, we found evidence of a positive predictive path between digital social engagement, general smartphone use, and physical activity-selectively under lockdown conditions (N = 127 individual users, M = 6201 daily observations). Further, we observed a positive relationship between social media use and total daily steps across individuals during (but not prior to) lockdown. Although there are important limitations on the validity of drawing causal conclusions from observational data, a plausible explanation for our findings is that, during lockdown, individuals use their smartphones to access social support, which may help guard against negative effects of in-person social deprivation and other pandemic-related stress. Importantly, passive monitoring of smartphone app usage is low burden and non-intrusive. Given appropriate consent, this could help identify people who are failing to engage in usual patterns of digital social interaction, providing a route to early intervention.

RESUMO

The inclusion of biosafety strategies into strain engineering pipelines is crucial for safe-by-design biobased processes. This in turn might enable a more rapid regulatory acceptance of bioengineered organisms in both industrial and environmental applications. For this reason, we equipped the industrially relevant microbial chassis Pseudomonas putida KT2440 with an effective biocontainment strategy based on a synthetic dependency on phosphite, which is generally not readily available in the environment. The produced PSAG-9 strain was first engineered to assimilate phosphite through the genome-integration of a phosphite dehydrogenase and a phosphite-specific transport complex. Subsequently, to deter the strain from growing on naturally assimilated phosphate, all native genes related to its transport were identified and deleted generating a strain unable to grow on media containing any phosphorous source other than phosphite. PSAG-9 exhibited fitness levels with phosphite similar to those of the wild type with phosphate, and low levels of escape frequency. Beyond biosafety, this strategy endowed P. putida with the capacity to be cultured under non-sterile conditions using phosphite as the sole phosphorous source with a reduced risk of contamination by other microbes, while displaying enhanced NADH regenerative capacity. These industrially beneficial features complement the metabolic advantages for which this species is known for, thereby strengthening it as a synthetic biology chassis with potential uses in industry, with suitability towards environmental release.

RESUMO

Mental disorders hamper immunological control of HIV infection by exerting a negative influence on antiretroviral therapy (ART) adherence. We sought to address the possible relationship between non-adherence to antiretroviral treatment (ART), mental disorders and substance use in people living with HIV/AIDS (PLWHA) in Spain, which presents a high prevalence of intravenously transmitted HIV infection. We assessed 125 PLWHA attending regular outpatient follow-up. The main adherence measure was pill collection from the Hospital Pharmacy. We included sociodemographic variables, mental disorders diagnosis, and substance use in the 12 months prior to the assessment. Harmful alcohol consumption (OR: 6.834; 95% CI: 2.008-23.257; p = 0.002), suffering from depression (OR: 5.851; 95% CI: 1.470-23.283; p = 0.012) and being at risk of suicide (OR: 3.495; 95% CI: 1.136-10.757; p = 0.029) increased the likelihood of non-adherence. 29.6% of the sample had been infected via blood contact. HCV co-infection was present in 46.4% of the study sample, increasing the likelihood of non-adherence (OR: 3.223; 95% CI: 1.119-9.286; p = 0.030). Harmful alcohol use and some serious mental disorders (especially depression and suicide risk) are consistently associated with non-adherence to ART. HCV co-infection could be an important risk marker of non-adherence among PLWHA with a high prevalence of intravenous drug use.

RESUMO

Latin American countries (LAC), with their culturally and ethnically diverse populations, form a region that is difficult to define and to understand. The region's health systems are deeply fragmented, which poses great challenges to overall equity levels in health. This is also one of the fastest ageing regions in the world, with increasing demands as well for acute and long-term care (LTC). Demographic and epidemiological transitions across the region are heterogeneous. In this context, health systems are in general, largely unprepared to face the challenge of promoting healthy ageing. This unpreparedness has been magnified by the Coronavirus disease-2019 pandemic. Here, we analyse the burden of disease in the older population and identify priorities to improve the care and quality of life for people living in LAC. Besides an adequately prepared workforce, we must remediate disparities and inequities; develop and implement integrated care; achieve patient-centred care and further develop palliative and end-of-life care; simultaneously, we must develop the structure and financing of LTC services and strengthen the role of public health making healthy ageing an essential component.

RESUMO

BACKGROUND: Medically serious suicide attempts (MSSA) represent a subgroup of clinically heterogeneous suicidal behaviours very close to deaths by suicide. A simple definition of an MSSA is a suicide attempt with life-threatening consequences, regardless of the severity of the attempter's mental disorder. Few studies have specifically analysed the heterogeneity of MSSA. Therefore, the aim of this study is to describe the profile of individuals who made a highly severe MSSA and to compare those admitted to Intensive Care Units (ICU) - including Burn Units- with other MSSA admitted to other medical and surgical units. METHODS: The study sample consisted of 168 patients consecutively admitted to non-psychiatric wards from two public hospitals in Barcelona after an MSSA during a 3-year period. In order to select more severe MSSA, the minimum hospital stay was expanded from Beautrais' definition of ≥ 24 h to ≥ 48 h. Mean hospital stay was 23.68 (SD = 41.14) days. Patients needing ICU treatment (n = 99) were compared to other MSSArs (n = 69) that were admitted to other medical and surgical units, not requiring intensive care treatment, with an initial bivariant analysis followed by a logistic regression analysis using conditional entrance. RESULTS: Medically serious suicide attempters (MSSArs) spent more time hospitalized, more frequently reported recent stressful life events, were more likely to have at least one prior suicide attempt (SA) and their current attempt was more frequently non-planned, compared to the profile of MSSArs reported in previous studies. The most frequent method was medication overdose (67.3%) and jumping from heights (23.2%). Among those who chose more than one method (37.6%), the most frequent combination was medication overdose and drug use. Affective disorders and personality disorders were the most frequent diagnoses. Higher educational level, history of previous mental disorders and prior lifetime suicide attempts were significantly more frequent among those admitted to ICU compared to other MSSArs. Patients needing admission to ICU less frequently used self-poisoning and cuts. CONCLUSIONS: MSSA needing ICU admission can be regarded clinically as similar to attempts resulting in suicide. More research on this type of highly severe suicide behaviour is needed due to its serious implications both from a clinical and public health perspective.

RESUMO

BACKGROUND: Contrast-induced nephropathy (CIN) is a major inconvenience in the use of iodinated contrast media (ICM) and it is associated with a significant increase in morbidity and mortality and cost of hospitalization. Remote ischemic preconditioning (RIPC) is a noninvasive and cost-effective tissue protection technique that has showed to be beneficial in decreasing renal insult in patients receiving intravascular contrast. AIM: The primary outcome of this study is to evaluate the impact of RIPC on the incidence of CIN in patients undergoing endovascular aneurysm repair. METHODS: Patients suffering from aortic aneurysm were recruited prior to the administration of ICM. Randomization was used to assign patients into the control/RIPC groups. Biochemical parameters determined renal function before and after surgery in immediate (24-72 hr) and at 30 days of follow-up. RESULTS: Of the 120 patients included in the study, 98,3% were male. Mean age was 73 years (range: 56-87 years). Diabetes and chronic renal failure (considering estimated glomerular filtration [eGFR] <60) was present prior to administration of ICM in 29.16% and 38.33%, respectively. RIPC was applied in 50% (n = 60) of the patients. A total of 24.17% developed CIN regardless of fluidotherapy, RIPC, and other protective strategies. RIPC did not influence outcomes in terms of incidence on CIN, serum creatinine, urea, eGFR, or microalbuminuria in immediate postoperative period. However, the group of RIPC patients showed a statistically significant benefit in renal function in terms of serum creatinine (1.46 ± 0.3 vs. 1.03 ± 0.5; P < 0.001), urea (61.06 ± 27.5 mg/dL vs. 43.78 ± 12.9 mg/dL; P = 0.003), and an increase in eGFR (56.37 ± 23.4 mL/min/1.73 m2 vs. 72.85 ± 17.7 mL/min/1.73 m2; P = 0.004) at 30 days of follow-up. CONCLUSIONS: RIPC seems to be a reasonable, effective, and low-cost technique to alleviate effects of ICM on the renal parenchyma in endovascular aneurysm repair procedures during short-term postoperative period.

RESUMO

BACKGROUND: Chronic physical conditions (CPC) decrease the quality of life of millions of people. In the absence of curative treatments, maintaining healthy lifestyle habits is one of the main pillars in their clinical management. Mobile-based interventions may help patients take care of their health and follow medical recommendations. The purpose of this review is to summarise the latest evidence about mobile telephone applications (apps) for the management of CPC. METHODS: We performed a systematic search of the PubMed and EMBASE databases to identify articles that explored apps for the management of CPC, testing the apps empirically and providing clear outputs on effectiveness and/or feasibility. A total of 3528 articles were identified in the initial search. Following screening and selection process, 20 articles were included in the final review. RESULTS: Mobile apps for CPC are very heterogeneous. The condition with the greater number of apps available was diabetes, followed by cardiovascular diseases. Results of feasibility were generally positive, with high rates of study completion and user engagement. Some studies used incentives, monetary of otherwise. Some of the apps have been tested in randomised controlled trials showing effectiveness in improving symptoms and/or controlling analytical parameters. CONCLUSIONS: Mobile apps are promising tools for the management of CPC. Some apps have been sufficiently tested to propose their implementation in clinical practice. However, several barriers exist that can slow down the routine use of new technologies in healthcare settings.
