RESUMEN

The concept of solar geoengineering remains a topic of debate, yet it may be an effective way for cooling the Earth's temperature. Nevertheless, the impact of solar geoengineering on regional or local climate patterns is an active area of research. This study aims to evaluate the impact of solar geoengineering on precipitation and temperature extremes of the Muda River Basin (MRB), a very important agricultural basin situated in the northern Peninsular Malaysia. The analysis utilized the multi-model ensemble mean generated by four models that contributed to the Geoengineering Model Intercomparison Project (GeoMIP6). These models were configured to simulate the solar irradiance reduction (G6solar) and stratospheric sulfate aerosols (G6sulfur) strategies as well as the moderate (SSP245) and high emission (SSP585) experiments. Prior to the computation of extreme indices, a linear scaling approach was employed to bias correct the daily precipitation, maximum and minimum temperatures. The findings show that the G6solar and G6sulfur experiments, particularly the latter, could be effective in holding the increases in both annual and monthly mean precipitation totals and temperature extremes close to the increases projected under SSP245. For example, both G6solar and G6sulfur experiments project increases of temperature over the basin of 2 °C at the end of the 21st century as compared to 3.5 °C under SSP585. The G6solar and G6sulfur experiments also demonstrate some reliability in modulating the increases in precipitation extreme indices associated with flooding to match those under SSP245. However, the G6sulfur experiment may exacerbate dry conditions in the basin, as monthly precipitation is projected to decrease during the dry months from January to May and consecutives dry days are expected to increase, particularly during the 2045-2064 and 2065-2084 periods. Increases dry spells could indirectly affect agricultural and freshwater supplies, and pose considerable challenges to farmers.

RESUMEN

Transgender and gender diverse youth and young adults (TGDY) experience higher mental health morbidity, including self-harm, suicide ideation, and suicide attempts, as compared to cisgender peers. Support from family members is associated with improved mental health outcomes for TGDY. However, little is known about the process that caregivers who consider themselves supportive undergo and how caregiver-youth relationships evolve through a TGDY's gender journey. Through a reflexive thematic analysis of 14 interviews conducted with caregivers of TGDY from April-July 2022, we sought to understand how caregivers who considered themselves supportive of TGDY navigated shifting relationships with themselves, their children, and their communities. Applying theories of Ambiguous Loss and Thriving Through Relationships, findings coalesced around several themes including reflecting on change, re-negotiating interpersonal relationships, and educating through relationships. The gender journeys of TGDY required caregivers to navigate relationships with self (feeling loss and wrestling with worry for their child), negotiate relationships with others (disclosing to extended family and social networks), and educate themselves and others through relationships (connecting through personal narratives from other families, parents supporting parents, learning to advocate for their child). The process of caregivers learning to support their children was facilitated through profound intrapersonal and interpersonal reflection, connection, and community. Understanding this process is important to inform educational interventions and programs that help caregivers learn to support and advocate effectively for TGDY.

RESUMEN

Efforts to improve sexual health outcomes among young cisgender women require in-depth understanding of how women with diverse sexual identities make decisions about their sexual health. We conducted semi-structured interviews with 31 young cisgender women with diverse sexual identities and histories (age range 18-29 (M = 23.32); 81% White; 29% bisexual, 26% heterosexual, 16% lesbian, 13% queer, 10% pansexual, 3% gay, 3% demisexual) about their decision-making surrounding sexual risk reduction. By conducting thematic analysis, we found that, regardless of partner sex or gender, women adapted sexual health strategies based on how much commitment, trust, and communication existed in their relationships. Because heteronormative structural influences limited access to information and safer sex options, women had to rely on trust and communication more with other women and partners with vaginas, compared to men and partners with penises. Women did not consider safer sex strategies with partners with vaginas (e.g. hand washing) risk-reduction techniques; instead, they considered them general hygiene or a way to take care of a partner. We propose that an inclusive model of young women's sexual decision-making should: (a) highlight the influence of relationships; (b) frame prevention in terms of overall health instead of pregnancy and STIs; and (c) acknowledge that structural factors, such as heteronormativity and sex-negativity, constrain women's decisions.

RESUMEN

Tributyltin (TBT) is a biocide used in the formulation of antifouling paints and it is highly harmful. Despite the ban, the compound persists in the environment, contaminating marine foodstuffs and household products. Therefore, considering the route of exposure to the contaminant, the gastrointestinal tract (GIT) acts as an important barrier against harmful substances and is a potential biomarker for understanding the consequences of these agents. This work aimed to evaluate histological and neuronal alterations in the duodenum of male Wistar rats that received 20 ng/g TBT and 600 ng/g via gavage for 30 consecutive days. After the experimental period, the animals were euthanized, and the duodenum was intended for neuronal histochemistry (total and metabolically active populations) and histological routine (morphometry and histopathology). The results showed more severe changes in neuronal density and intestinal morphometry in rats exposed to 20 ng/g, such as total neuronal density decrease and reduction of intestinal layers. In rats exposed to 600 ng/g of TBT, it was possible to observe only an increase in intraepithelial lymphocytes. We conclude that TBT can be more harmful to intestinal homeostasis when consumed in lower concentrations.

RESUMEN

The invisibility of lesbian, gay, and bisexual (LGB+) women in sexual health research is of particular concern when it comes to understanding and supporting their sexual health practices. We conducted a qualitative secondary analysis of sexual health decision-making interviews among 22 LGB+ cisgender women who ranged in age from 20 to 26 (M = 23.1 years, SD = 1.8 years). Participants were mostly bisexual (n = 9), White (n = 13), and all reported at least some college education. Results showed that LGB+ women both reify and push against heteronormativity in their sexual partnerships. By queering definitions of "sex" beyond heterosexual intercourse, leaning into trust as a foundation of new sexual partnerships, and promoting accessible and realistic hygienic strategies for STI prevention, LGB+ women queer, or reimagine, new sexual scripts. These results highlight the need for relationship and sexual health scholars to direct focus toward the promotion of holistic sexual and relationship education and research which reflects LGB+ women's various sexual desires, goals and needs. Understanding LGB+ women's sexual scripts and health outcomes will ensure that this population continues to be validated and supported by clinicians, researchers, and educators.

RESUMEN

BACKGROUND: Patients with immune-mediated thrombotic thrombocytopenic purpura (iTTP) have anti-ADAMTS-13 immunoglobulin G (IgG) autoantibodies that enhance ADAMTS-13 clearance and/or inhibit its function. ADAMTS-13 normally circulates in a closed conformation, which is manifested by the interaction of the CUB domains with the central spacer domain. Disruption of the spacer-CUB interaction opens ADAMTS-13, which augments its proteolytic function but may also expose cryptic autoimmune epitopes that promote further autoantibody recognition. OBJECTIVES: To explore differences in autoantibody binding to ADAMTS-13 in its closed or open conformations in patients with iTTP and to correlate these differences with disease-related parameters. METHODS: We developed a novel assay to measure autoantibodies binding to closed and open ADAMTS-13. Autoantibody titer and IgG subclass binding to open or closed ADAMTS-13 were measured in 70 iTTP first presentation samples and correlated with clinical data, remission, and relapse. RESULTS: In 70 patients with iTTP, the mean autoantibody titer against open ADAMTS-13 was, on average, approximately 2-fold greater than that against closed ADAMTS-13, suggesting that ADAMTS-13 opening increases epitope exposure and immune complex formation. Autoantibody titer against closed/open ADAMTS-13 and IgG subclass did not correlate with ADAMTS-13 antigen at presentation. Two patients with iTTP and persistent autoantibodies lost specificity for closed ADAMTS-13 in remission. Recognition of closed/open ADAMTS-13 and autoantibody IgG subclass between the first and second iTTP episodes were very similar. CONCLUSION: ADAMTS-13 autoantibody binding is highly influenced by ADAMTS-13 conformation. Although this does not appear to modify the pathogenicity of autoantibodies, the autoantibody signature at relapse suggests that relapse represents re-emergence of the original autoimmune response rather than de novo presentation.

RESUMEN

Terpenes are a major class of secondary metabolites present in all plants, and long hypothesized to have diversified in response to specific plant-herbivore interactions. Herbivory is a major biotic interaction that plays out across broad temporal and spatial scales that vary dramatically in temperature regimes, both due to climatic variation across geographic locations as well as the effect of seasonality. In addition, there is an emerging understanding that global climate change will continue to alter the temperature regimes of nearly every habitat on Earth over the coming centuries. Regardless of source, variation in temperature may influence herbivory, in particular via changes in the efficacy and impacts of plant defensive chemistry. This study aims to characterize temperature-driven variation in toxicological effects across several structural classes of terpenes in the model herbivore Vanessa cardui, the painted lady butterfly. We observed a general increase in monoterpene toxicity to larvae, pupa, and adults at higher temperatures, as well as an increase in development time as terpene concentration increased. Results obtained from this study yield insights into possible drivers of seasonal variation in plant terpene production as well as inform effects of rising global temperatures on plant-insect interactions. In the context of other known effects of climate change on plant-herbivore interactions like carbon fertilization and compensatory feeding, temperature-driven changes in plant chemical defense efficacy may further complicate the prediction of climate change impacts on the fundamental ecological process of herbivory.

RESUMEN

We investigated parasitic zoonoses caused by protozoans and helminths in urban and peri-urban rat populations (Rattus norvegicus and R. rattus) in Spanish cities. Rats were trapped and then dissected to remove adult helminths, and the contents of the large intestine were retrieved for the study of parasitic forms. The Midi Parasep® solvent free (SF) technique was used to concentrate the parasites in the intestinal contents. Some of the rats studied (n = 8) were infected by the rat lungworm, Angiostongylus cantonensis, whose first stage larvae (L1) are shed in rat faeces. After the concentration technique, L1 larvae were found in the sediment of 6 of the 8 positive rats. The two negative sediment samples were due to the presence of either only adult females or, in addition to males, only young females in the lungs of the rats. In view of our results, Midi Parasep® SF turned out to be a simple, rapid, inexpensive, and sensitive method to detect nematode larvae, such as the L1 larvae of A. cantonensis (or A. costaricensis), in natural and experimentally infected rats.

RESUMEN

BACKGROUND: Severe deficiency in ADAMTS-13 (<10%) and the loss of von Willebrand factor-cleaving function can precipitate microvascular thrombosis associated with thrombotic thrombocytopenic purpura (TTP). Patients with immune-mediated TTP (iTTP) have anti-ADAMTS-13 immunoglobulin G antibodies that inhibit ADAMTS-13 function and/or increase ADAMTS-13 clearance. Patients with iTTP are treated primarily by plasma exchange (PEX), often in combination with adjunct therapies that target either the von Willebrand factor-dependent microvascular thrombotic processes (caplacizumab) or the autoimmune components (steroids or rituximab) of the disease. OBJECTIVES: To investigate the contributions of autoantibody-mediated ADAMTS-13 clearance and inhibition in patients with iTTP at presentation and through the course of the PEX therapy. PATIENTS/METHODS: Anti-ADAMTS-13 immunoglobulin G antibodies, ADAMTS-13 antigen, and activity were measured before and after each PEX in 17 patients with iTTP and 20 acute TTP episodes. RESULTS: At presentation, 14 out of 15 patients with iTTP had ADAMTS-13 antigen levels of <10%, suggesting a major contribution of ADAMTS-13 clearance to the deficiency state. After the first PEX, both ADAMTS-13 antigen and activity levels increased similarly, and the anti-ADAMTS-13 autoantibody titer decreased in all patients, revealing ADAMTS-13 inhibition to be a modest modifier of the ADAMTS-13 function in iTTP. Analysis of ADAMTS-13 antigen levels between consecutive PEX treatments revealed that the rate of ADAMTS-13 clearance in 9 out of 14 patients analyzed was 4- to 10-fold faster than the estimated normal rate of clearance. CONCLUSION: These data reveal, both at presentation and during PEX treatment, that antibody-mediated clearance of ADAMTS-13 is the major pathogenic mechanism that causes ADAMTS-13 deficiency in iTTP. Understanding the kinetics of ADAMTS-13 clearance in iTTP may now enable further optimization of treatment of patients with iTTP.

RESUMEN

Yeast surface display (YSD) has been extensively used for protein design, engineering, and directed evolution in the past two decades. Here, we describe methods for directed evolution of tissue inhibitors of metalloproteinase (TIMP), the natural inhibitors of matrix metalloproteinases (MMPs), through design and generation of a combinatorial library of TIMP mutants and screening the targeted TIMP library of variants toward MMP binding using YSD. This protocol can be adopted to other natural enzyme inhibitors and similar protein binders such as antibodies.

RESUMEN

Infection with the SARS-CoV-2 virus, resulting in COVID-19 disease, has presented a unique scenario associated with high rates of thrombosis. The risk of venous thrombosis is some three- to sixfold higher than for patients admitted to a hospital for other indications, and for patients who have thrombosis, mortality appears to increase. Thrombosis may be a presenting feature of COVID-19. Pulmonary thrombi are the most frequent events, some related to deep vein thrombosis, but also to in situ microvascular and macrovascular thrombosis. Other venous thromboses include catheter- and circuit-associated in patients requiring hemofiltration and extracorporeal membrane oxygenation. Arterial thrombosis is less commonly documented, with 3% of patients in intensive care units having major arterial strokes and up to 9% having myocardial infarction, both of which are most likely multifactorial. Risk factors for thrombosis above those already documented in hospital settings include duration of COVID-19 symptoms before admission to the hospital. Laboratory parameters associated with higher risk of thrombosis include higher D-dimer, low fibrinogen, and low lymphocyte count, with higher factor VIII and von Willebrand factor levels indicative of more severe COVID-19 infection. All patients should receive thromboprophylaxis when admitted with COVID-19 infection, but the dose and length of treatment are still debated. Thrombosis continues to be treated according to standard VTE guidelines, but adjustments may be needed depending on other factors relevant to the patient's admission.

RESUMEN

Management of soft tissue avulsion after facial bites could be challenging in some situation. We presented the case of a 32 years old men suffering from a full thickness avulsion of the left lower lip and cheek after a dog bite. Even if the lip fragment was initially put on the bin, a microvascular replantation was performed. The vascularization was based on the left inferior labial artery. No veins were found. We used post-operative leech therapy to avoid venous congestion during 10 days. A large antibiotherapy was conducted. Adaptation of antibiotics blood concentration was also necessary due to the permanent bleeding caused by leech therapy. At the 6 month consultation, the patient recovered an impressive labial function and sensibility. Replantation gives the best functional and esthetical outcomes in these rare and complex cases. Artificial blood drainage, large antibiotic therapy and close post-operative follow-up are significant parts of the replantation success.

RESUMEN

Although control efforts are improving, vector-borne diseases remain a global public health challenge. There is a need to shift vector control paradigms while developing new products and programmes. The importance of modifying vector behaviour has been recognised for decades but has received limited attention from the public health community. This study aims to: (1) explore how the use of spatial repellents at sublethal doses could promote public health worldwide; (2) propose new methods for evaluating insecticides for use by the general public; and (3) identify key issues to address before spatial repellents can be adopted as complementary vector control tools. Two field experiments were performed to assess the effects of an insecticidal compound, the pyrethroid transfluthrin, on Aedes albopictus mosquitoes. The first examined levels of human protection, and the second looked at mosquito knockdown and mortality. For the same transfluthrin dose and application method, the percent protection remained high (>80%) at 5 h even though mosquito mortality had declined to zero at 1 h. This result underscores that it matters which evaluation parameters are chosen. If the overarching goal is to decrease health risks, sublethal doses could be useful as they protect human hosts even when mosquito mortality is null.

RESUMEN

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a potentially fatal thrombotic microangiopathy caused by autoantibody-mediated severe deficiency of ADAMTS13. Standardized definitions of response, exacerbation, remission, and relapse were initially proposed in 2003 and modified by the International Working Group for TTP in 2017. These definitions, which have been widely used in clinical practice and research, are based primarily on the platelet count and are benchmarked against the timing of discontinuation of therapeutic plasma exchange (TPE). They do not incorporate ADAMTS13 activity or the temporizing effects on the platelet count of caplacizumab, a novel anti-von Willebrand factor (VWF) nanobody. In light of these limitations, the IWG aimed to develop revised consensus outcome definitions that incorporate ADAMTS13 activity and the effects of anti-VWF therapy, by using an estimate-talk-estimate approach. The updated definitions distinguish clinical remission and clinical relapse (defined primarily by platelet count) from ADAMTS13 remission and ADAMTS13 relapse (defined by ADAMTS13 activity). The revised definitions of exacerbation and remission are benchmarked against not only the timing of discontinuation of TPE but also that of anti-VWF therapy. Retrospective validation of the revised definitions is described, although they have yet to be prospectively validated. Clinical implications of the updated outcome definitions are also discussed and an example of their application to clinical practice is provided to highlight their clinical relevance.

RESUMEN

OBJECTIVES: To summarise and synthesise findings from qualitative primary research studies of nursing students' experiences from educational activities using manikins to gain a deeper understanding of the role these manikins play in the students' learning. DESIGN AND DATA SOURCES: A systematic review and thematic metasynthesis were conducted. Cinahl+, Ovid Medline, ERIC and Embase were searched systematically. REVIEW METHODS: Sandelowski and Barroso's framework guided the review process. A comprehensive search to identify qualitative studies of nursing students' experiences from learning with manikins was performed in January 2019 and updated in April 2020. Study selection was guided by six screening questions derived from these inclusion criteria: qualitative primary studies, published from 2008, in English or Scandinavian, presenting findings of undergraduate nursing students' experiences with manikins at all fidelity levels. Thomas and Harden's method for thematic synthesis was followed. RESULTS: Twenty-eight articles of twenty-seven studies were included. We identified three synthesised analytic themes: Seeing the manikin as a doll or a patient, Experiencing yourself as a nurse caring for a patient, and Being a team member. CONCLUSIONS: When it is perceived as a patient, a manikin can give students a realistic experience of what it means to behave like nurses. Consequently, this realism lets students practice and acquire relational, communicative, and collaborative nursing skills. Using a manikin can facilitate the development of students' professional identity.

RESUMEN

Background: Brain health is a multi-faceted concept used to describe brain physiology, cognitive function, mental health and well-being. Diseases of the brain account for one third of the global burden of disease and are becoming more prevalent as populations age. Diet, social interaction as well as physical and cognitive activity are lifestyle factors that can potentially influence facets of brain health. Yet, there is limited knowledge about the population's awareness of brain health and willingness to change lifestyle to maintain a healthy brain. This paper introduces the Global Brain Health Survey protocol, designed to assess people's perceptions of brain health and factors influencing brain health. Methods: The Global Brain Health Survey is an anonymous online questionnaire available in 14 languages to anyone above the age of 18 years. Questions focus on (1) willingness and motivation to maintain or improve brain health, (2) interest in learning more about individual brain health using standardized tests, and (3) interest in receiving individualized support to take care of own brain health. The survey questions were developed based on results from a qualitative interview study investigating brain health perceptions among participants in brain research studies. The survey includes 28 questions and takes 15-20 min to complete. Participants provide electronically informed consent prior to participation. The current survey wave was launched on June 4, 2019 and will close on August 31, 2020. We will provide descriptive statistics of samples distributions including analyses of differences as a function of age, gender, education, country of residence, and we will examine associations between items. The European Union funded Lifebrain project leads the survey in collaboration with national brain councils in Norway, Germany, and Belgium, Brain Foundations in the Netherlands and Sweden, the National University of Ostroh Academy and the Women's Brain Project. Discussion: Results from this survey will provide new insights in peoples' views on brain health, in particular, the extent to which the adoption of positive behaviors can be encouraged. The results will contribute to the development of policy recommendations for supporting population brain health, including measures tailored to individual needs, knowledge, motivations and life situations.

RESUMEN

Changes in environmental conditions, whether related or not to human activities, are continuously modifying the geographic distribution of vectors, which in turn affects the dynamics and distribution of vector-borne infectious diseases. Determining the main ecological drivers of vector distribution and how predicted changes in these drivers may alter their future distributions is therefore of major importance. However, the drivers of vector populations are largely specific to each vector species and region. Here, we identify the most important human-activity-related and bioclimatic predictors affecting the current distribution and habitat suitability of the mosquito Culex pipiens and potential future changes in its distribution in Spain. We determined the niche of occurrence (NOO) of the species, which considers only those areas lying within the range of suitable environmental conditions using presence data. Although almost ubiquitous, the distribution of Cx. pipiens is mostly explained by elevation and the degree of urbanization but also, to a lesser extent, by mean temperatures during the wettest season and temperature seasonality. The combination of these predictors highlights the existence of a heterogeneous pattern of habitat suitability, with most suitable areas located in the southern and northeastern coastal areas of Spain, and unsuitable areas located at higher altitude and in colder regions. Future climatic predictions indicate a net decrease in distribution of up to 29.55%, probably due to warming and greater temperature oscillations. Despite these predicted changes in vector distribution, their effects on the incidence of infectious diseases are, however, difficult to forecast since different processes such as local adaptation to temperature, vector-pathogen interactions, and human-derived changes in landscape may play important roles in shaping the future dynamics of pathogen transmission.

RESUMEN

Thrombotic microangiopathy (TMA) is a syndrome involving fragmentation haemolysis, thrombocytopenia, and thrombosis. A range of disorders including cancer may have TMA as a clinical manifestation. TMA in cancer may be caused by several mechanisms, including systemic microvascular metastases, but may also be due to extensive bone marrow involvement with cancer or secondary necrosis. Chemotherapeutic agents may also cause associated TMA through a range of different mechanisms. Gemcitabine, platinum-based drugs, mitomycin C, and proteasome inhibitors are known to cause TMA in cancer patients. Transplant-associated TMA (TA-TMA) may affect either solid organ or HSCT patients. TA-TMA remains a difficult complication to address due to its high mortality rate, lack of standard diagnostic criteria, and limited therapeutic options. The challenge of cancer-associated TMA is furthered by the fact that plasma exchange is ineffective in its management.

RESUMEN

Convective precipitation is intensifying in many regions, but potential implications of shifts in precipitation types on impacts have not been quantified. Furthermore, risk assessments often focus on rare extremes, but also more frequent hydro-meteorological events burden private and public budgets. Here synoptic, hydrological, meteorological, and socio-economic data are merged to analyse 25 years of damage claims in 480 Austrian municipalities. Exceedance probabilities of discharge and precipitation associated with damage reports are calculated and compared for convective and stratiform weather patterns. During April to November, 60% of claims are reported under convective conditions. Irrespective of the weather type, most of the accumulated cost links to minor hazard levels, not only indicating that frequent events are a highly relevant expense factor, but also pointing to deficiencies in observational data. High uncertainty in damage costs attributable to extreme events demonstrates the questionable reliability of calculating low-frequency event return levels. Significant differences exist among weather types. Stratiform weather types are up to 10 times more often associated with damaging extreme discharge or precipitation, while convective weather shows the highest nuisance level contributions. The results show that changes in convective precipitation are pertinent to risk management as convective weather types have contributed significantly to damage in the past.

RESUMEN

BACKGROUND: Guidelines do not recommend that cancer outpatients receive thromboprophylaxis unless at high venous thromboembolism (VTE) risk, with the Khorana score suggested for risk stratification. This study investigated VTE incidence in outpatients with pancreatic, endometrial, colorectal, ovarian and cervical cancer, the role of Khorana score in risk assessment and potential risk factors. METHODS: Data were retrospectively collected 1 year after cancer diagnosis. VTE associated with inpatient admissions was excluded. RESULTS: Seven hundred forty-six patients were included. VTE rates varied: 26.8% pancreatic; 5.7% endometrial; 9.8% colorectal; 10.2% ovarian; and 0.0% cervical cancer. Excluding VTE at diagnosis, potentially preventable VTE rates were 16.5% in pancreatic, 3.8% in endometrial, 9.8% in colorectal and 8.7% in ovarian cancer. Khorana score was associated with VTE in endometrial cancer only (high-risk: 16.7% vs. low-risk: 1.5%; P < 0.001). VTE rates for patients with central venous catheters (CVCs) were 22.6-34.8% in pancreatic, endometrial, colorectal and ovarian cancers. VTE was associated with CVCs in endometrial, colorectal and ovarian; chemotherapy and Hb < 100 g/L in pancreatic; surgery in endometrial and ovarian; and body mass index > 35 in ovarian cancers following adjusted analysis (P < 0.05). CONCLUSIONS: VTE is a significant burden in pancreatic, endometrial, colorectal and ovarian cancers. Khorana score was not predictive in most cancers. The major VTE-associated variable was CVC. Our data suggest a role for clinical trials of thromboprophylaxis in targeted cancer outpatients.
