We examined (1) how interviewers construct fit perceptions about applicants and (2) the relationship between these perceptions and actual hiring recommendations. It was hypothesized that actual demographic similarity and human capital similarity would indirectly affect fit perceptions. These fit perceptions would be predicted by the interviewer's perceived similarity to applicants, mediated by two factors: interviewers' liking of the applicant and interviewers' expectations of applicant performance. Actual interviewer-applicant dyads (N=118) were studied. The results indicated that the relationship between perceived similarity and fit perceptions is mediated by performance expectations but not by liking. This study provides evidence that interviewers are more rational than previous research suggested. However, the fact that human resource interviewers are more likely to perceive applicants as similar to themselves than line interviewers suggests that interviewers' neutrality is questioned.

Background: Since 2015, ~ 8 million Venezuelans have fled what was once Latin America's most prosperous nation, with many relocating to nearby Colombia and others migrating to the United States (U.S.). Emerging research suggests that migration-related cultural stress is a challenge for Venezuelans and is related to an increased risk of mental health problems. However, it remains uncertain how cultural stress and mental health outcomes manifest over time and across countries., Methods: We use independent sample t-tests to compare survey data from multiple studies of Venezuelan migrants in Bogotá and Medellín, Colombia, and the U.S. State of Florida. Data collected include self-report measures on discrimination, negative context of reception (NCR), and depression and post-traumatic stress disorder (PTSD) screening diagnoses, collected from distinct cross-national cohorts in 2017 (N = 638) and 2023-2024 (N = 1241)., Results: Self-reported NCR and discrimination were consistently higher among Venezuelan migrants in Colombia than among Venezuelans in Florida. Levels of cultural stress within countries were variable, with NCR decreasing across years in Florida and discrimination increasing in both Florida and Colombia. Many Venezuelan migrants reported symptoms of mental health problems, with half of the sample in Colombia (54-56%) and two-fifths of the sample in Florida (39-41%) screening positive for depression in 2017 and 2023-2024. Individuals exposed to higher levels of cultural stress were substantially more likely to screen positive for depression and PTSD., Conclusions: This study is the first to examine cultural stress and mental health among Venezuelan migrants across national contexts and different stages of the still-unfolding international migration crisis., Competing Interests: Declarations.

Background and Purpose: Levodopa-entacapone-carbidopa intestinal gel (LECIG) infusion is a recently developed device-aided therapy for advanced Parkinson disease (PD) patients. The aim of this study was to report real-world evidence about the effectiveness, tolerability, and safety of LECIG in PD patients., Methods: A multicenter observational retrospective study of the first patients who initiated LECIG in Spain was performed. All neurologists with an experience of at least two patients treated until 30 March 2024 were invited to participate. Data about effectiveness and safety from the medical records (V0, pre-LECIG; V1, initiation of LECIG; V2, post-LECIG follow-up) with a total of 246 variables were collected., Results: Seventy-three PD patients (61.6% males, 70.1 ± 9.1 years old) from 21 Spanish centers with a mean disease duration of 14.4 ± 6.3 years (range = 5-31) were included. Twenty-six patients (35.6%) were switched directly from levodopa-carbidopa intestinal gel. The mean exposure to LECIG was 177.3 ± 110.5 days (range = 7-476). The mean daily OFF time decreased from 5.2 ± 3 (pre-LECIG) to 1.9 ± 1.8 (post-LECIG; n = 66, p < 0.0001). Global improvement was observed in >85% of the patients. No significant change was detected in the levodopa equivalent daily dose from V0 to V2. Only 7% received 24-h infusion, and 24.7% required more than one cartridge per day at V2. Thirty-four patients (46.6%) had at least one adverse event related to LECIG and/or the device system. Five patients (6.8%) discontinued LECIG., Conclusions: LECIG was safe and effective in advanced PD patients., (© 2024 The Author(s).

As climate change continues to displace greater numbers of people, transnational ties are important sources of social protection for climate migrants. Migrants assemble unique configurations of formal and informal social protections depending on the resources available within their sending and receiving communities. However, the specific constellations of social protections that climate migrants use following disaster and displacement remain underexamined. Authors conducted semistructured interviews with Puerto Ricans who migrated in the aftermath of Hurricane Maria (N = 41) and used qualitative content analysis to trace the assemblages of formal and informal social protections used to navigate the resettlement process. Results suggest that informal support from migrants' transnational ties was instrumental in successfully making use of formal sources of support, including federal emergency relief programs, to leave the island and resettle on the U.S. mainland. This reliance on informal social protections often strained participants' informal networks and raised questions of equity for people internally displaced by climate change. These findings highlight the need for a more equitable and effective linkage of climate migrants with public resources., (© 2024 National Association of Social Workers.)

Objectives: A growing body of research points to a relationship between exposure to migration-related cultural stress and mental health problems. However, such research is often conducted with the tacit assumption that postmigration experiences are the primary-if not singular-driver of psychological distress. In the present study, we aim to extend the cultural-stress paradigm by examining the influences of both premigration crisis exposure and postmigration cultural stress on depression in a sample of Venezuelan crisis migrants in Colombia., Method: Survey data for the present study were collected from Venezuelan youth ( N = 429, ages 12-17, M age = 14.0 years, 49% female) and adults ( N = 566, ages 18+, M age = 35.1 years, 82% female) in Bogota and Medellin, Colombia between April and June 2023., Results: Both crisis exposure and discrimination were independently related to depressive symptoms. However, when examined in a multivariate model along with discrimination, crisis exposure was not a significant predictor of depressive symptoms among youth, and its influence weakened considerably among adults. Among both youth and adults, a Crisis Exposure × Discrimination interaction term significantly predicted depressive symptoms, indicating that discrimination was a more robust predictor of depressive symptoms among those endorsing lower levels of crisis exposure than among those reporting high levels of crisis exposure., Conclusion: Our research provides new insights into the experiences of Venezuelan migrant youth and adults in Colombia. It provides further support for the importance of drawing from a crisis-informed cultural-stress framework when working with crisis migrant populations.

In the aftermath of Hurricane María's devastating impact on Puerto Rico in September 2017, a wave of migration to the continental United States followed. Despite Puerto Rico's territorial association with the United States, its distinct culture and language often render its migrants as cultural minorities who are often treated as foreigners. Prior research has indicated that natural disasters can have a profound effect on the family unit, so examining the experiences of displacement and resettlement of Puerto Rican parents can shed light on the challenges faced by these families. Using cultural stress theory and psychological sense of community as guiding frameworks, this qualitative study aimed to explore the experience of Puerto Rican parents displaced to the United States following Hurricane María. A total of 42 Puerto Rican Hurricane María migrant parents agreed to participate in semistructured interviews. Our findings illuminate a trade-off in the lives of Puerto Rican migrants: As they departed their homeland, they exchanged social connections, support networks, and the vibrant social fabric of Puerto Rico for the promise of economic stability, reduced crime, and enhanced prospects for themselves and their children in the United States. This study represents a crucial contribution to the understanding of Puerto Ricans who have embarked on the challenging journey of relocating in the aftermath of Hurricane María. It underscores how they grapple with the multifaceted challenges and benefits inherent in their roles as cross-cultural climate migrants, transitioning from the predominantly Spanish-speaking, Latin American context of Puerto Rico to the diverse landscape of the United States.

Introduction: Acute retinal necrosis (ARN) is a severe eye disease demanding swift treatment to prevent blindness. Early action involving antiviral medications and corticosteroids is crucial for optimal visual outcomes., Objective: We present an ARN case series showcasing treatment experience and results., Methodology: Patients diagnosed with ARN based on SUN Working Group 2021 criteria were included; all underwent comprehensive eye exams, PCR analysis, and imaging., Results:  Eight patients were studied; PCR confirmed ARN in six. Induction treatment, either oral valacyclovir (5/8) or intravenous acyclovir (3/8), lasted 10-14 days. Maintenance included oral valacyclovir (6/8), oral valganciclovir (2/8) for six months, along with intravitreal ganciclovir. Visual outcomes were similar for oral and intravenous therapies; poor baseline acuity and macular involvement tend to result in a worse final acuity., Conclusions: Swift treatment is vital to ARN management. Our findings emphasize effective treatment strategies' role in visual prognosis., Abbreviations: ACV: Acyclovir; BCVA: Best Corrected Visual Acuity; CMV: Cytomegalovirus; EBV: Epstein Barr Virus; FTA-ABS: Fluorescent treponemal antibody absorption test; HSV 1-2: Herpes simplex virus 1-2; HIV: Human Immunodeficiency Virus; IV-ACV: Intravenous- Acyclovir; PCR: Polymerase Chain Reaction;Tg: Toxoplasma gondii ; VZV: Varicella Zoster Virus; VCV: Valacyclovir; VDRL: Venereal disease research laboratory test.

There is scarce information about the effect of sperm morphology and seminal plasma composition on cat semen freezability. Thus, this study aims to assess the effect of cat sperm morphology and seminal plasma cholesterol (CHOL) and triacylglyceride (TAG) concentrations on sperm post-thaw survival. Ejaculates (n = 49) were evaluated, and seminal plasma was separated and frozen until CHOL and TAG concentrations were measured. The sperm pellet was diluted in a tris-based egg yolk extender, frozen (n = 38), or processed for sperm ultrastructure study (n = 11). Abnormalities recorded were abnormal head shape and size, detached heads, knobbed or ruffled acrosomes, eccentric mid-piece insertion, proximal and distal cytoplasmic droplets, folded and coiled tails, and Dag defect. Ultramicroscopic evaluation detected several sperm abnormalities in fresh semen and some sperm damage in frozen semen. Seminal plasma lipids components were positively correlated with post-thaw motility and acrosome integrity. Higher freezability indices for motility and acrosome integrity were observed in frozen-thawed semen with high seminal plasma CHOL and TAG concentrations. No freezability differences were observed between teratozoospermic and normozoospermic ejaculates. Our results showed that even when seminal plasma was removed before cryopreservation, sperm survival after thawing was significantly higher in samples with high seminal plasma CHOL and TAG concentrations, indicating a rapid adherence to these compounds to the sperm plasma membrane, protecting sperm cells from temperature changes. Nevertheless, there were no differences in sperm freezability by sperm morphology., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Sugarcane production has been linked to the release of heavy metals and metalloids (HM/MTs) into the environment, raising concerns about potential health risks. This study aimed to assess the levels of 19 HM/MTs in children living near a sugarcane mill through a pilot biomonitoring investigation. We investigated sex-related differences in these element levels and their correlations. A cross-sectional study was conducted, analyzing data from 20 children in the latter part of 2023. Spearman correlation coefficients with 95% confidence intervals (CIs) were used to assess the relationships between urinary HM/MT levels. Detectable levels of 17 out of the 19 HM/MTs were found across the entire study sample, with arsenic and copper detectable in 95% of the children. Titanium exhibited higher levels in boys compared to girls (p = 0.017). We identified 56 statistically significant correlations, with 51 of them being positive, while the remaining coefficients indicated negative relationships. This study characterized HM/MT levels in school-aged children residing near a sugarcane mill through a pilot biomonitoring investigation. Further research employing larger sample sizes and longitudinal assessments would enhance our understanding of the dynamics and health impacts of HM/MT exposure in this vulnerable population.

Environmental exposure to heavy metals and metalloids, originating from sources such as mining and manufacturing activities, has been linked to adverse renal effects. This cross-sectional study assessed children's exposure to these elements and its association with urinary kidney injury molecule-1 (KIM-1). We analyzed data from 99 school-aged children residing in nine localities within the state of Colima, Mexico, during the latter half of 2023. Levels of 23 metals/metalloids and urinary KIM-1 were measured using inductively coupled plasma mass spectrometry (ICP-MS) and enzyme-linked immunosorbent assay, respectively. Detectable levels of these contaminants were found in over 91% of participants, with varied exposure profiles observed across locations ( p = 0.019). After adjusting for confounding factors like gender, age, and locality, higher levels of six metals/metalloids (boron, cadmium, cesium, lithium, selenium, zinc) were significantly associated with increased KIM-1 levels. Tailored mitigation efforts are crucial to protect children from regional pollutant burdens. However, limitations exist, as our study did not capture all potential factors influencing heavy metal/metalloid and KIM-1 levels., (© 2024. The Author(s).)

Aim: ChiTn, a mouse/human chimeric anti-Tn monoclonal antibody, was radiolabeled with iodine-131 ( 131 I) and technetium-99m ( 99m Tc) to assess its biodistribution and internalization in Tn-expressing (Tn+) and wild-type (Tn-) LL/2 lung cancer cells. Results: Selective accumulation and gradual internalization of ChiTn were observed in Tn+ cells. Biodistribution in mice with both Tn+ or Tn- lung tumors indicated that the uptake of radiolabeled ChiTn within tumors increased over time. Dual-labeling experiments with 99m Tc and 131 I showed different biodistribution patterns, with 99m Tc exhibiting higher values in the liver, spleen, and kidneys, while 131 I showed higher uptake in the thyroid and stomach. However, tumor uptake did not significantly differ between Tn+ and Tn- tumors. To improve tumor targeting, Losartan, an antihypertensive drug known to enhance tumor perfusion and drug delivery, was investigated. Biodistribution studies in Losartan-treated mice revealed significantly higher radiolabeled ChiTn uptake in Tn+ tumors. No significant changes were observed in the uptake of the control molecule IgG-HYNIC™ 99m Tc. Conclusions: These findings demonstrate the enhanced tumor targeting of radiolabeled ChiTn in Losartan-treated mice with Tn-expressing lung tumors. They highlight the potential of ChiTn as a theranostic agent for cancer treatment and emphasize the importance of Losartan as an adjunctive treatment to improve tumor perfusion and drug delivery.

Hurricane María caused significant devastation on the island of Puerto Rico, impacting thousands of lives. Puerto Rican crisis migrant families faced stress related to displacement and relocation (cultural stress), often exhibited mental health symptoms, and experienced distress at the family level. Although cultural stress has been examined as an individual experience, little work has focused on the experience as a family. To address this gap, we conducted a mixed-methods study designed to examine the predictive effects of cultural stress on family conflict and its mental health implications among Puerto Rican Hurricane María parent and child dyads living on the U.S. mainland. In the quantitative phase of the study, 110 parent-child dyads completed an online survey assessing cultural stress, family dynamics, and mental health. As part of our primary analysis, we estimated a structural equation path model. Findings from the quantitative phase showed a significant positive relationship between family cultural stress and family conflict, as well as individual parent and child mental health symptoms. In the qualitative phase of the study, 35 parent-child dyads participated in individual interviews. Findings from the interviews revealed variations in difficulties related to language, discrimination, and financial burdens, with some participants adapting more quickly and experiencing fewer stressors. Findings also highlight the impact on mental health for both parents and youth, emphasizing the family-level nature of cultural stress, while noting a potential discrepancy between qualitative and quantitative findings in the discussion of family conflict., (© 2024 Family Process Institute.)

Emerging research provides insights into migration-related cultural stress experiences and mental health among Venezuelan migrants; however, prior studies have not considered the critical distinction between online xenophobia and in-person discrimination. To address this gap, we assess the psychometric properties of an abbreviated version of the Perceived Online Racism Scale (PORS) with Venezuelan migrant youth and examine the interplay between online xenophobia, in-person discrimination, and mental health. Survey data were collected from Venezuelan migrant youth ( N = 319; ages 13-17, 49.5% female) in Colombia in April-July 2023. Confirmatory factor analysis (CFA) was used to examine the PORS, and multiple regression was conducted to examine key associations. The CFA showed excellent model fit: χ²(7) = 13.498, p = .061; comparative fit index = .989; Tucker-Lewis index = .977; root-mean-square error of approximation = .055; standardized root-mean-square residual = .026. Controlling for demographic factors, online xenophobia was associated with depressive symptoms (β = .253, p < .001) and anxiety (β = .200, p = .001). The online xenophobia-mental health association weakened when controlling for in-person discrimination but remained nevertheless significant (depression: β = .181, p = .002, anxiety: β = .135, p = .026). Interaction effects (Online × In-Person) revealed a pattern in which greater exposure to online xenophobia was associated with greater distress, but only at relatively low levels of in-person discrimination. Findings provide new insights regarding (a) the properties of an increasingly relevant measure of cultural stress, (b) how online xenophobia relates to mental health, and (c) the interplay of online and in-person cultural stressors vis-à-vis mental health among Venezuelan migrant youth.

Fluid status (FS) is a diagnostic challenge in critically ill patients with COVID-19. Here, we compared parameters related to FS derived from cumulative fluid balance (CFB), bioelectrical impedance analysis (BIA) and venous congestion assessed by ultrasound (VExUS) to predict mortality. We retrospectively reviewed the medical records of individuals with severe pneumonia due to COVID-19 between July and November 2021 in a single center. Comorbidities, demographic, clinical and laboratory data as well as results from CFB, BIA and VExUS measurements were collected on admission and weekly afterwards for two consecutive evaluations. Seventy-nine patients were included, of which eighteen (14.2%) died. Abnormalities of FS were only identified by BIA. Extracellular water/total body water ratio (ECW/TBW) > 0.394 (overhydrated) by BIA was a good predictor of mortality (AUC = 0.78, 95% CI: 0.067-0.89). Mortality risk was higher in overhydrated patients (OR: 6.2, 95% CI: 1.2-32.6, p = 0.02) and in persistently overhydrated patients (OR: 9.57, 95% CI: 1.18-77.5, p = 0.03) even after adjustment to age, serum albumin and acute kidney injury (AKI) in stages 2-3. Time to death was shorter in overhydrated patients (HR: 2.82, 95% CI: 1.05-7.5, log-rank test p = 0.03). Abnormalities in FS associated with mortality were only identified by BIA in critically ill patients with COVID-19.

Objective: The objective of the study was to explore red cell distribution width (RDW) as a surrogate marker of inflammation, alone and in conjunction with muscle wasting to predict malnutrition-related adverse outcomes., Methods: This was a single-center observational study including adult hospitalized patients. Demographic variables, malnutrition criteria, and RDW were captured within 24 hours of hospital admission. Correlation tests and regression models were performed between these variables (RDW and muscle wasting) and adverse outcomes (in-hospital mortality and unplanned transfer to critical care areas (CCA)., Results: Five hundred and forty-five patients were included in the final analysis. Muscle wasting showed an independent association with adverse outcomes in every regression model tested. RDW alone showed fair predictive performance for both outcomes' significance and the adjusted model with muscle wasting showed association only for unplanned transfer to CCA., Conclusion: RDW did not improve the prediction of adverse outcomes compared to muscle wasting assessed by physical examination and simple indexes for acute and chronic inflammation. Malnourished patients presented higher RDW values showing a possible metabolic profile (higher inflammation and lower muscle). It is still unknown whether nutrition support can influence RDW value over time as a response marker or if RDW can predict who may benefit the most from nutritional support., (Copyright: © 2024 Permanyer.)

Background: Angiogenesis is a process that many tumors depend on for growth, development, and metastasis. Vascular endothelial growth factor (VEGF) is one of the major players in tumor angiogenesis in several tumor types, including melanoma. VEGF inhibition is achieved by bevacizumab, a humanized monoclonal antibody that binds with high affinity to VEGF and prevents its function. In order to successfully enable in vivo VEGF expression imaging in a murine melanoma model, we previously labeled bevacizumab with [ 99m Tc]Tc. We observed that this was feasible, but it had prolonged blood circulation and delayed tumor uptake., Objective: The aim of this study was to develop a radiolabeled Fab bevacizumab fragment, [ 99m Tc]Tc-HYNICFab( bevacizumab), for non-invasive in vivo VEGF expression molecular imaging., Methods: Flow cytometry was used to examine VEGF presence in the murine melanoma cell line (B16-F10). Bevacizumab was digested with papain for six hours at 37°C to produce Fab(bevacizumab), which was then conjugated to NHS-HYNIC-Tfa for radiolabeling with [ 99m Tc]Tc. Stability and binding affinity assays were also evaluated. Biodistribution and single photon emission computed tomography/computed tomography (SPECT/CT) were performed at 1, 3, and 6 h (n = 4) after injection of [ 99m Tc]Tc-HYNIC-Fab(Bevacizumab) in normal and B16-F10 tumor-bearing C57Bl/6J mice., Results: Using flow cytometry, it was shown that the B16-F10 murine melanoma cell line has intracellular VEGF expression. Papain incubation resulted in the complete digestion of bevacizumab with good purity and homogeneity. The radiolabeling yield of [ 99m Tc]Tc-HYNIC-Fab(bevacizumab) was 85.00 ± 6.06%, with a specific activity of 291.87 ± 18.84 MBq/mg (n=3), showing in vitro stability. Binding assays demonstrated significant intracellular in vitro VEGF expression. Fast blood clearance and high kidney and tumor uptake were observed in biodistribution and SPECT/CT studies., Conclusions: We present the development and evaluation of [ 99m Tc]Tc-HYNIC-Fab(bevacizumab), a novel molecular VEGF expression imaging agent that may be used for precision medicine in melanoma and potentially in other VEGF-expressing tumors., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Female gender could be a cause of diagnostic delay in inflammatory bowel disease (IBD). The aim of this study was to investigate the diagnostic delay in women vs men and potential causes., Methods: This multicenter cohort study included 190 patients with recent diagnosis of IBD (disease duration <7 months). Reconstruction of the clinical presentation and diagnostic process was carried out in conjunction with the semistructured patient interview, review, and electronic medical records., Results: The median time from symptom onset to IBD diagnosis was longer in women than in men: 12.6 (interquartile range, 3.7-31) vs 4.5 (2.2-9.8) months for Crohn's disease (CD; P = .008) and 6.1 (3-11.2) vs 2.7 (1.5-5.6) months for ulcerative colitis (UC; P = .008). Sex was an independent variable related to the time to IBD diagnosis in Cox regression analysis. The clinical presentation of IBD was similar in both sexes. Women had a higher percentage of misdiagnosis than men (CD, odds ratio [OR], 3.9; 95% confidence [CI], 1.5-9.9; UC, OR 3.0; 95% CI, 1.2-7.4). Gender inequities in misdiagnosis were found at all levels of the health system (emergency department, OR 2.4; 95% CI, 1.1-5.1; primary care, OR 2.5; 95% CI, 1.3-4.7; gastroenterology secondary care, OR 3.2; 95% CI, 1.2-8.4; and hospital admission, OR 4.3; 95% CI, 1.1-16.9)., Conclusions: There is a longer diagnostic delay in women than in men for both CD and UC due to a drawn-out evaluation of women, with a higher number of misdiagnoses at all levels of the health care system., (© 2023 Crohn’s & Colitis Foundation.

Objectives: Following Hurricane Maria, scores of Puerto Rican "Maria migrants" fled the island with thousands permanently resettling on the United States (U.S.) mainland. Emerging evidence suggests that many Maria migrants are exposed to migration-related cultural stressors, including discrimination, negative context of reception, and language stress. The present study examines the associations of premigration hurricane trauma and postmigration cultural stress with posttraumatic stress disorder (PTSD) symptom severity and positive PTSD screens., Method: Participants were 319 adult (age 18+, 71% female) Puerto Rican Hurricane Maria survivors on the U.S. mainland. Data were collected virtually between August 2020 and October 2021. Participants completed Spanish-language measures of hurricane-related trauma, postmigration cultural stress exposure, PTSD symptoms, and positive screens., Results: One in five (20.5%) Maria migrants reported PTSD scores in the range indicating a likely PTSD diagnosis (i.e., positive screen of 50+). Both hurricane trauma and migration-related cultural stressors independently predicted posttraumatic stress and positive PTSD screens. Additionally, controlling for the effect of hurricane trauma, discrimination and language stress were strongly linked with PTSD. Further, hurricane trauma and cultural stressors interact such that cultural stress predicts PTSD-positive screens at low-to-moderate levels of hurricane trauma exposure but not at high-to-very-high levels., Conclusion: Findings underscore the importance of providing mental health and other psychosocial supports to hurricane survivors and evacuees beyond the immediate aftermath of the disaster, and the need to consider both premigration trauma and postmigration experiences in terms of the mental health of crisis migrant populations.

The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes without cumulus are markedly low. This study assessed the integrity of capacitated bovine sperm acrosome when exposed to increasing concentrations of P4, and evaluated whether exogenous P4 during in vitro fertilization (IVF) increases the developmental competence of partially cumulus-denuded oocytes in serum-free conditions. After a 4-h capacitation induction, sperm were incubated with increasing concentrations of P4 (0, 0.1, 10 and 100 μM) and evaluated for viability, caspase activation and acrosome status at three different times (4, 5, and 22 h), including the capacitation induction period. Progesterone induced sperm acrosomal exocytosis without compromising sperm viability or activating sperm caspases. Sperm undergoing acrosome reaction exhibited three differential Concanavalin A patterns, corresponding to early, intermediate and late acrosomal exocytosis. The percentage of these patterns significantly increased over time, regardless of P4 concentration, except for those spermatozoa with late acrosomal exocytosis, which only showed an increase at 22 h of incubation. After incubation for 1 h with 100 μM P4, spermatozoa showing intermediate acrosomal exocytosis significantly increased. At 22 h of incubation, the pattern corresponding to early acrosomal exocytosis evidenced a dose-dependent increase. However, prematurely high levels of acrosome reaction induced by 100 μM P4 led to inefficient IVF outcomes (P < 0.05). Therefore, IVF trials with partially cumulus-denuded oocytes were carried out with lower P4 concentrations (0, 0.1, 1, 5, 10 μM). Cleavage rate significantly increased at 1 μM P4, which translated to increased total embryo production after 7 days of in vitro culture (P < 0.05). Significantly higher percentages of expanded blastocysts were observed at both 1 μM and 10 μM P4 as compared to the other experimental conditions. In conclusion, the different patterns of acrosomal exocytosis identified over time by incubation of live sperm with a fluorescent lectin revealed the existence of sperm subpopulations heterogeneous in their physiological states. Moreover, exogenous P4 at 1 μM during IVF improved the developmental competence of partially cumulus-denuded oocytes in serum-free conditions., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: The asbestos industry began its operations in Colombia in 1942 with the establishment of an asbestos-cement facility in Sibaté, located in the Department of Cundinamarca. Despite extensive asbestos use and production in Colombia, the country lacks a reliable epidemiological surveillance system to monitor the health effects of asbestos exposure. The Colombian health information system, known as SISPRO, did not report mesothelioma cases diagnosed in the municipality, posing a significant challenge in understanding the health impacts of asbestos exposure on the population of Sibaté., Methods: To address this issue, an active surveillance strategy was implemented in Sibaté. This strategy involved conducting door-to-door health and socioeconomic structured interviews to identify Asbestos-Related Diseases (ARDs). Validation strategies included a thorough review of medical records by a panel of physicians, and the findings were communicated to local, regional, and national authorities, as well as the general population., Results: The active surveillance strategy successfully identified a mesothelioma cluster in Sibaté, revealing the inadequacy of the existing health information system in monitoring asbestos-related diseases. The discovery of this cluster underscores the critical importance of implementing active surveillance strategies in Colombia, where governmental institutions and resources are often limited., Conclusion: The findings of this study emphasize the urgent need for Colombia to establish a reliable epidemiological surveillance system for asbestos-related diseases (ARDs). Active surveillance strategies can play a crucial role in identifying mesothelioma clusters and enhancing our understanding of the health effects of asbestos exposure in low- and middle-income countries., Competing Interests: The authors declare no financial conflict of interest. The following authors reported that they served as expert witness in court trials on asbestos-related diseases: C.M., P.C., B.T.. J.P.R.-B. was invited, between 2015 and 2019, ad honorem, to provide his expert opinion in the Colombian Senate in support of a national asbestos ban that had been proposed, a ban that was finally approved in 2019., (Copyright: © 2023 The Author(s).)

As the construction industry moves towards greater sustainability, the application of more durable and environmentally friendly materials, capable of providing comfort in buildings and infrastructure, is a key element to consider. In this context, the use of alkali-activated binders (AAB) and geopolymers (GP), which have a lower carbon footprint than ordinary Portland cement (OPC), has emerged as an important alternative. Moreover, the addition of waste-based lightweight aggregates (LWA) to AAB and GP matrices produces lightweight composites that offer enhanced mechanical performance and improved comfort as building materials, while offering an alternative use to the increasing number of waste materials from diverse sources. This paper presents a comprehensive review of the literature on the above-mentioned topics (waste LWA in an AAB/GP matrix) published between 2012 and 2023, mainly indexed in the Scopus database. The waste-based LWA reported in the literature were categorized, and their properties and morphology presented. Then, the influence of the size, quantity, and nature of the LWA on the composite's properties and performance was analyzed. Fresh state performance, mechanical performance, density, and thermal and acoustic insulation were considered. This review is complemented by a bibliometric analysis, where keyword correlation and co-authorship networks on this field are established. The review highlights the potential of cementitious composites including waste-based LWA as a sustainable building material for structural and non-structural applications. However, more studies are required to further understand the behaviour of these composites under innovative manufacturing processes, such as extrusion and 3D printing., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Objective: We examine the interplay of acculturation orientation, cultural stress, and hurricane trauma exposure with behavioral health among Puerto Rican crisis migrants who relocated to the US mainland after Hurricane Maria., Method: Participants were 319 adult (M age  = 39 years; 71% female; 90% arriving in 2017-2018) Hurricane Maria survivors surveyed on the US mainland. Latent profile analysis was used to model acculturation subtypes. In turn, ordinary least squares regression was executed to examine the associations of cultural stress and hurricane trauma exposure with behavioral health while stratifying by acculturation subtype., Results: Five acculturation orientation subtypes were modeled, three of which-Separated (24%), Marginalized (13%), and Full Bicultural (14%)-align closely with prior theorizing. We also identified Partially Bicultural (21%) and Moderate (28%) subtypes. Stratifying by acculturation subtype, with behavioral health (depression/anxiety symptoms) specified as the dependent variable, hurricane trauma and cultural stress accounted for only 4% of explained variance in the Moderate class, a somewhat greater percentage in the Partial Bicultural (12%) and Separated (15%) classes, and substantially greater amounts of variance in the Marginalized (25%) and Full Bicultural (56%) classes., Conclusion: Findings underscore the importance of accounting for acculturation in understanding the relationship between stress and behavioral health among climate migrants., (© 2023 The Authors.

Asbestos is a carcinogenic mineral banned in Colombia since 1 January 2021; however, there is a considerable amount of asbestos-containing building materials (ACBM) installed across the country in products such as roof tiles, tanks, pipes, and downspouts. Installed ACBM represent an exposure risk when the mineral fibers are released into the air through deterioration, damage, or disturbance of the cement matrix within which the asbestos is contained. Due to potential detrimental impacts on human health, safe management and correct handling of ACBM is a matter of vital importance. This article proposes evidence-based environmental management guidelines, aimed at public policymaking, for the removal and final disposal of installed ACBM in Colombia. A descriptive study was carried out, with a qualitative approach, based on an integrative literature review of international practices applied in the removal and disposal of installed ACBM. Forty scientific publications were reviewed, as well as the regulations for removal, transport, and final disposal of installed asbestos-cement from Australia, the USA, Italy, Chile, the UK, and Canada. Guidelines for the removal and final disposal of installed ACBM are proposed, suggesting the following stages: (a) diagnosis and management plan of installed ACBM, (b) removal of installed ACBM, (c) transport of ACBM waste, and (d) final disposal of ACBM waste. Expert opinion was collected to assess the local feasibility of the proposed guidelines. These guidelines may help direct national and regional agencies to establish comprehensive strategies with clear, measurable, and achievable goals for future replacement of installed ACBM.

Favipiravir is an important selective antiviral that emerged as an alternative against COVID-19 during the pandemic. Its synthesis has gained great interest and the conventional strategies proceed through multiple-step protocols (6-7 reaction steps), which involve, in addition, several drawbacks with global yields, lower than 34%. Herein, a simple, economical, eco-friendly and scalable (1 g) one-step protocol for the synthesis of favipiravir from the direct fluorination of the available 3-hydroxy-2-pyrazinecarboxamide with Selectfluor® is reported. The reaction proceeds easily in BF 4 -BMIM through a simple operational work-up, affording the favipiravir with a yield of 50% without the need of a special catalyst/additive. The key point of the present strategy was the use of the ionic liquid of BF 4 -BMIM, which helps to minimize the several chemical limitations derived from 3-hydroxy-2-pyrazinecarboxamide as a substrate for the direct Selectfluor-mediated fluorination. All these chemical reactivity aspects are also discussed in detail.

Glioblastoma (GBM), as the most central nervous system (CNS) intractable disease, has spoiled millions of lives due to its high mortality. Even though several efforts have been made, the existing treatments have had limited success. In this sense, we studied a lead compound, the boron-rich selective epidermal growth factor receptor (EGFR)-inhibitor hybrid 1 , as a potential drug for GBM treatment. For this end, we analyzed the in vitro activity of hybrid 1 in a glioma/primary astrocytes coculture, studying cellular death types triggered by treatment with this compound and its cellular localizations. Additionally, hybrid 1 concentrated boron in glioma cells selectively and more effectively than the boron neutron capture therapy (BNCT)-clinical agent 10 B-l-boronophenylalanine and thus displayed a better in vitro -BNCT effect. This encouraged us to analyze hybrid 1 in vivo . Therefore, immunosuppressed mice bearing U87 MG human GBM were treated with both 1 and 1 encapsulated in a modified liposome (recognized by brain-blood barrier peptide transporters), and we observed a potent in vivo per se antitumor activity (tumor size decrease and animal survival increase). These data demonstrate that 1 could be a promising new targeted therapy for GBM.

The domestic cat is a highly prolific species; thus, reproductive control is crucial to reducing feral cat overpopulation. This study aimed to assess the effect of a commercially-available GnRH vaccine for swine on suppressing sperm production in male cats. Twelve sexually mature tomcats were randomly divided into two groups. Treated cats (n = 9) received a GnRH vaccine (Improvac, Zoetis Belgium SA, 0.5 mL sc) twice 4 wk apart, and the control group (CON, n = 3) saline solution (0.5 mL sc). Reproductive parameters and blood samples were recorded every 2 wk, from 6 wk before vaccination until 24 wk after the first dose. Day 0 of the study was defined as the day of primary immunization with either the vaccine or saline solution. Serum testosterone concentrations of treated cats dropped to basal levels 6 wk after D0, while CON cats maintained serum testosterone concentrations between normal ranges during the study period. No differences were observed in pretreatment and CON seminal samples. However, a progressive decrease in seminal quality was observed in treated cats from wk 8 until the end of the study. By wk 24, sperm concentration and total sperm count decreased by 90%, motility decreased by 70%, and viability decreased by 60%. Moreover, testicular volume was reduced by 49%, and penile spines showed almost complete atrophy by the end of the study. Although treated cats showed a decrease in the hematocrit, erythrocyte count, and hemoglobin concentration, values were within the reference range for domestic cats. No differences were observed in the other hematological and biochemical parameters evaluated. Our results agree with previous immunocontraception studies in cats, showing that Improvac vaccination effectively reduced sperm quality, testicular volume, and serum testosterone concentration. Further studies should be carried out to define the Improvac long-term effect., Competing Interests: Declaration of competing interest The authors declared no potential conflicts of interest concerning this article's research, authorship, and/or publication., (Copyright © 2022.

Introduction: One of the main contributors to cognitive reserve (CR) is the involvement in cognitively stimulating activities (CSAs), including education, work, leisure, social and physical activities. Personality traits are plausible determinants of CR, influencing the tendency to engage in CSAs. The goal of this study was to evaluate the association between personality and CR, operationalised as self-rated involvement in CSAs, in a sample of individuals aged 18-50 or more. Method: We collected two-wave non-probabilistic online data throughout Mexico. The instruments were the Big Five Inventory-2 for the baseline, its extra-short form for the follow-up and the Self-Rating of Cognitive Reserve (SRCR). Confirmatory factor analyses (CFAs) were performed to test the unifactorial structure of the SRCR, and multiple regressions were conducted with personality factors as predictors of CR. Results: For the baseline, 2025 participants were recruited, and 610 for the follow-up, most of them female and aged 18-40. CFAs showed excellent goodness-of-fit, and the regression analyses proved Negative Emotionality and Extraversion to be the main predictors of CR. Conclusions: Our study highlights the need to identify personality profiles at high risk of underdevelopment of CR in ages where it is still feasible to promote engagement in CSAs.

Asbestos (all forms, including chrysotile, crocidolite, amosite, tremolite, actinolite, and anthophyllite) is carcinogenic to humans and causally associated with mesothelioma and cancer of the lung, larynx, and ovary. It is one of the carcinogens most diffuse in the world, in workplaces, but also in the environment and is responsible for a very high global cancer burden. A large number of countries, mostly with high-income economies, has banned the use of asbestos which, however, is still widespread in low- and middle-income countries. It remains, thus, one of the most common occupational and environmental carcinogens worldwide. Italy issued an asbestos ban in 1992, following the dramatic observation of a large increase in mortality from mesothelioma and other asbestos-related diseases in exposed workers and also in subjects with non-occupational exposure. A mesothelioma registry was also organized and still monitors the occurrence of mesothelioma cases, conducting a case-by-case evaluation of asbestos exposure. In this report, we describe two Italian communities, Casale Monferrato and Broni, that faced an epidemic of mesothelioma resulting from the production of asbestos cement and the diffuse environmental exposure; we present the activity and results of the Italian mesothelioma registry (ReNaM), describe the risk-communication activities at the local and national level with a focus on international cooperation and also describe the interaction between mesothelioma registration and medical services specialized in mesothelioma diagnosis and treatment in an area at high risk of mesothelioma. Finally, we assess the potential application of the solutions and methods already developed in Italy in a city in Colombia with high mesothelioma incidence associated with the production of asbestos-cement materials and the presence of diffuse environmental asbestos pollution.

Introduction: In 1994, Claudio Bassi reported a case of medical treatment for infected pancreatic necrosis (IPN); then since 1996 numerous articles of case series were published with treatment only with antibiotics with good outcomes., Objectives: To present our experience in the management of patients with IPN with antibiotics (without drainage)., Methods: We retrospectively reviewed cases with a diagnosis of IPN from January 2018 to October 2020, focusing on those cases that were treated conservatively (hydro-electrolyte, nutritional support and antibiotics). The diagnosis was made by observing gas in the retroperitoneum by CT or by clinical deterioration of the patient with pancreatic necrosis without another focus. Fine needle aspiration was not performed., Results: We identified 25 patients with a diagnosis of IPN; eleven were treated conservatively. According to Atlanta, modified in 2012, 3 were classified severely and the rest moderately severe. All received antibiotics for at least 3 weeks. None required parenteral nutrition. The mean hospital stay was 38 days. Three patients were readmitted. 8 underwent cholecystectomy after having resolved the condition; the rest were already cholecystectomized. There were no deaths in this series., Conclusions: IPN can be treated conservatively without drainage with good results in selected cases.

This study aimed to assess 1) the effect of high environmental temperatures on sperm production and 2) the effectiveness of a temperature-humidity index (THI) to predict the degree of thermal stress in a cat model. Semen collection was performed by electroejaculation for 18 mo in 20 tomcats maintained under controlled photoperiod. Still, temperature and humidity were not experimentally manipulated to describe the effect of natural climate conditions on seminal samples. Ejaculates (n = 512) were then grouped according to temperature records of the sampling day and compared by temperature and THI index. Significant lower sperm parameters and increase sperm tail abnormalities were observed during warm environments (temperature and THI). Concentration and total sperm count were the most affected parameters. Environmental temperatures of 28.5 °C with 54% relative humidity (THI = 77.07) and 27.9 °C with 66% humidity (THI = 77.84) were upper thresholds of moderate thermal stress. Moreover, days with relative humidity near 90% led to severe thermal stress with temperatures as low as 26.6 °C (THI = 78.88). The current study demonstrates the detrimental effect of high environmental temperatures on sperm quality in the domestic cat. This effect is observed at lower temperatures when high relative humidity is present. In this sense, the THI was a reliable predictor of the magnitude of thermal stress experienced by cats. Thus, cats from reproductive programs should be maintained under controlled photoperiod cycles with temperatures around 20 °C and humidity around 70% to avoid semen detrimental effects., (Copyright © 2022 Elsevier Inc.

Socioeconomic inequalities in the detection and treatment of non-communicable diseases represent a challenge for healthcare systems in middle-income countries (MICs) in the context of population ageing. This challenge is particularly pressing regarding hypertension due to its increasing prevalence among older individuals in MICs, especially among those with lower socioeconomic status (SES). Using comparative data for China, Colombia, Ghana, India, Mexico, Russia and South Africa, we systematically assess the association between SES, measured in the form of a wealth index, and hypertension detection and control around the years 2007-15. Furthermore, we determine what observable factors, such as socio-demographic and health characteristics, explain existing SES-related inequalities in hypertension detection and control using a Blinder-Oaxaca decomposition. Results show that the prevalence of undetected hypertension is significantly associated with lower SES. For uncontrolled hypertension, there is evidence of a significant gradient in three of the six countries at the time the data were collected. Differences between rural and urban areas as well as lower and higher educated individuals account for the largest proportion of SES-inequalities in hypertension detection and control at the time. Improved access to primary healthcare in MICs since then may have contributed to a reduction in health inequalities in detection and treatment of hypertension. However, whether this indeed has been the case remains to be investigated., Competing Interests: The authors have declared that no competing interests exist.

Since the discovery of antibiotics, humanity has been able to cope with the battle against bacterial infections. However, the inappropriate use of antibiotics, the lack of innovation in therapeutic agents, and other factors have allowed the emergence of new bacterial strains resistant to multiple antibiotic treatments, causing a crisis in the health sector. Furthermore, the World Health Organization has listed a series of pathogens (ESKAPE group) that have acquired new and varied resistance to different antibiotics families. Therefore, the scientific community has prioritized designing and developing novel treatments to combat these ESKAPE pathogens and other emergent multidrug-resistant bacteria. One of the solutions is the use of combinatorial therapies. Combinatorial therapies seek to enhance the effects of individual treatments at lower doses, bringing the advantage of being, in most cases, much less harmful to patients. Among the new developments in combinatorial therapies, nanomaterials have gained significant interest. Some of the most promising nanotherapeutics include polymers, inorganic nanoparticles, and antimicrobial peptides due to their bactericidal and nanocarrier properties. Therefore, this review focuses on discussing the state-of-the-art of the most significant advances and concludes with a perspective on the future developments of nanotherapeutic combinatorial treatments that target bacterial infections.

Objective: To analyze the psychological and functional sequelae of the COVID-19 pandemic among older adults living in long term care facilities (LTCFs)., Design: Cohort longitudinal study SETTING ANT PARTICIPANTS: A total of 215 residents ≥ 65 years without moderate-to-severe cognitive impairment, living in five LTCFs in Albacete (Spain)., Measurements: Baseline on-site data were collected between March - June 2020 and three-month follow-up between June to September 2020. Symptoms of depression, anxiety, posttraumatic stress disorder (PTSD), and sleep disturbances were measured as psychological variables. Disability in basic activities of daily living (BADL), ambulation and frailty were assessed as functional variables. Differences were analyzed in relation to level of comorbidity and test positivity for COVID-19., Results: At baseline, residents with COVID-19 presented worse functionality, higher frailty levels and malnutrition risk compared to non-COVID-19 residents. At three-month follow-up, higher rates of clinically significant depressive symptoms (57.7%), anxiety symptoms (29.3%), PTSD symptoms (19.1%) and sleep disturbances (93.0%) were found among residents regardless of COVID status. Thus, among 215 residents, 101 (47%) experienced a decline in BADL from baseline to the 3-month follow-up (median functional loss = 5 points in Barthel Index). In multivariate analyses, COVID-19 status did not explain either the functional or the ambulation loss. By contrast, residents with low comorbidity and COVID-19 presented higher PTSD symptoms (effect 2.58; 95% CI 0.93 to 4.23) and anxiety symptoms (effect 2.10; 95% CI 0.48 to 3.73) compared to the low comorbidity/non-COVID19 group., Conclusion: COVID-19 pandemic was associated, after three-months, with high psychological impact in older adults in LTCFs., specifically with higher post-traumatic stress and anxiety symptoms. Functional decline did not differ in relation to COVID-19 status but could be related to isolation strategies used for pandemic control., (Copyright © 2022. Published by Elsevier Inc.)

Background: Patients with inflammatory bowel disease (IBD) are vulnerable to some psychological disorders. Here we describe the psychological impact of a COVID-19 pandemic lockdown in patients with IBD., Methods: This multicenter prospective cohort study included 145 patients recently diagnosed with IBD. Data on clinical and demographic characteristics, anxiety and depression scales, and IBD activity were collected in two telephone surveys, during and after the first COVID-19 lockdown in Spain. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated., Results: During lockdown, 33.1% and 24.1% scored high on the anxiety and depression scales, respectively. Independent factors related to anxiety (all values ORs; 95% CIs) during lockdown were female sex (2; 1.2-5.4) and IBD activity (4.3; 1.8-10.4). Factors related to depression were comorbidity (3.3; 1.1-9.8), IBD activity (6; 1.9-18.1), use of biologics (2.9; 1.1-7.6), and living alone or with one person (3.1; 1.2-8.2). After lockdown, anxiety and depression symptoms showed significant improvement, with 24.8% and 15.2% having high scores for anxiety and depression, respectively. Factors related to post-lockdown anxiety were female sex (2.5; 1.01-6.3), Crohn's disease (3.3; 1.3-8.5), and active IBD (4.1; 1.2-13.7). Factors associated with depression were previous history of mood and/or anxiety disorders (6.3; 1.6-24.9), active IBD (7.5; 2.1-26.8), and steroid use (6.4; 1.4-29)., Conclusions: Lockdown during the COVID-19 pandemic had a significant psychological impact in patients with IBD. Disease activity was related to the presence of anxiety and depression symptoms during and after lockdown., (Copyright © 2021 Elsevier España, S.L.U. All rights reserved.)

The recent enactment of the law banning asbestos in Colombia raises a significant number of challenges. The largest factories that have historically processed asbestos include five asbestos-cement facilities located in the cities of Sibaté (Cundinamarca), Cali (Valle del Cauca), and Barranquilla (Atlántico), and Manizales (Caldas), which has two, as well as a friction products facility in Bogotá D.C. An asbestos chrysotile mine has also operated in Colombia since 1980 in Campamento (Antioquia). In the framework of developing the National Asbestos Profile for Colombia, in this study, we estimated the population residing in the vicinity of asbestos processing plants or the mine and, therefore, potentially at risk of disease. Using a geographic information system, demographic data obtained from the last two general population censuses were processed to determine the number of people living within the concentric circles surrounding the asbestos facilities and the mine. In previous studies conducted in different countries of the world, an increased risk of asbestos-related diseases has been reported for people living at different distance bands from asbestos processing facilities. Based on these studies, circles of 500, 1000, 2000, 5000, and 10,000 m radii, centered on the asbestos processing facilities and the mine that operated in Colombia, were combined with the census data to estimate the number of people living within these radii. Large numbers of people were identified. It is estimated that in 2005, at the country level, 10,489 people lived within 500 m of an asbestos processing facility or mine. In 2018, and within a distance of 10,000 m, the number of people was 6,724,677. This information can aid public health surveillance strategies.

(1) Background: Multiple sclerosis (MS) is a neurodegenerative disease characterized by pronounced inflammation. Interleukin 6 (IL-6) is an accurate marker for the state of inflammation, due to the high levels of this cytokine linked to the pathogenesis of the disease. These IL-6 levels could be lowered with an adequate dietary intake of vitamin D. The objective of the study was to determine the level of vitamin D ingested in a sample of patients with MS in the Valencian region (Spain), to establish the vitamin sources, and the possible link between the intake of vitamin D and the pathogenesis of the disease through a relationship with the level of IL-6. (2) Materials and Methods: A descriptive pilot study was carried out with 39 patients with MS in the Valencian region. The dietary-nutritional anamnesis was gained through the food frequency questionnaire (FFQ) and a food diary. Diet and eating habits were analyzed through the Easy Diet (version: 2.0.1)-Consultation Management Program ® software, and IL-6 levels in blood by ELISA technique. (3) Results: The results show a low intake of vitamin D, which is significantly and negatively related to the intake of proteins of vegetable origin, which are consumed in less quantity than proteins of animal origin, and significantly and negatively related with the high blood levels of IL-6, possibly as a consequence of the high intake of fats, mainly unsaturated. (4) Conclusions: MS patients in the Valencian region ingest little vitamin D related to low intake of vegetable protein, which would explain the high levels of IL-6 linked to the high intake of mainly saturated fats.

Introduction: Engagement and co-production in healthcare research and innovation are crucial for delivering person-centred interventions in underserved communities, but the knowledge of effective strategies to target this population is still vague, limiting the provision of person-centred care. Our research aimed to identify essential knowledge to foster engagement and co-production., Materials and Methods: A meta-synthesis research design was used to compile existing qualitative research papers on health communication, engagement, and empowerment in vulnerable groups in high-income countries (HICs) from 2008 to 2018. A total of 23 papers were selected and analysed., Results: 'Design and recruitment' and 'engagement and co-production' thematic areas are presented considering the factors related to researcher-communities attunement and the strategical plans for conducting research. The insights are discussed in light of the literature. Long-term alliances, sustainable structures, and strengthened bonds are critical factors for producing real long-term change, empowering persons and communities, and paving the way to person-centred care., Conclusions: The enhancement of the recruitment, involvement, and empowerment of traditionally disengaged communities and individuals depends on the awareness and analysis of social determinants, power differentials and specific tactics, and the capacity of researchers and individuals to apply all these principles in real-world practice.

This research evaluated the potential photocatalytic efficiency of synthesized Cu-Fe/TiO 2 photocatalysts against organic contaminants and biocontaminants through various synthesis methods (Cu-to-Fe ratio, metal loading, and calcination temperature) and reaction parameters (photocatalyst dose, irradiation time, and different initial methyl orange (MO) concentrations). In addition, the best photocatalysts were characterized through Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), differential reflectance spectroscopy (DRS), and X-ray photoelectron spectroscopy (XPS) analysis techniques. The best metal loading was 1 wt % with 5:5 Cu/Fe ratio and 300 °C calcination temperature (5Cu-5Fe/TiO 2 -300) having 97% MO decolorization. Further analysis indicates that the metal presence does not generate new channels for de-excitation but clearly affects the intensity and decreases charge recombination. The behavior of the photoluminescence intensity is (inversely) proportional to the activity behavior through the series, indicating that the main catalytic effect of Fe and Cu relates to charge recombination and that the Cu-Fe bimetallic catalyst optimizes such function. Moreover, the best-engineered photocatalysts asserted impactful bacteriostatic efficacy toward the tested Escherichia coli strain (in 30 min), and therefore, molecular docking studies were used to predict the inhibition pathway against E. coli β-lactamase enzyme. The photocatalyst had a high negative docking score (-5.9 kcal mol -1 ) due to intense interactions within the active site of the enzyme. The molecular docking study revealed that the ligand could inhibit β-lactamase from producing its bactericidal activity., Competing Interests: The authors declare no competing financial interest., (© 2021 The Authors.

The present study aimed to determine the effect of cat seminal plasma and purified llama ovulation-inducing factor (β-NGF) on ovarian activity in queens. Queens (n = 6) were used for all the treatments in a crossover design with an interval time between treatments of three interestrus intervals. Forty-eight hours after the detection of an estrus vaginal cytology, queens were given cat seminal plasma (subcutaneous or intramuscular), purified llama ovulation-inducing factor (15 or 35 μg), hCG (75 UI), saline, or were mated with a male. A total of 192 estrous cycles were observed. Estrus length and serum estradiol concentration were 6 ± 1 days (range 2-10 d) and 38 pg/mL (range 10-75 pg/mL), respectively. Queens mated and given hCG showed higher serum progesterone concentration and longer interestrus interval (47 ± 5 d) than that of controls (10 ± 3 d). Sixty-seven percent of queens (4/6) treated with subcutaneous cat seminal plasma, and 17% of those treated with purified llama β-NGF showed high serum progesterone concentrations along with prolonged interestrus. However, intramuscular administration of cat seminal plasma produced interestrus intervals similar to controls (15 ± 5 d) and basal serum progesterone concentration (<0.50 ng/mL). This study demonstrates that the subcutaneous administration of cat seminal plasma induced ovulation in queens. Therefore, molecules present in cat seminal plasma, contribute to the induction of ovulation in queens. Identifying those molecules will improve the knowledge of queen's reproductive physiology. Also, it could offer a physiologic alternative to induce ovulation in queens when reproductive biotechnologies are used., Competing Interests: Declaration of competing interest The authors declared no potential conflicts of interest concerning the research, authorship, and/or publication of this article., (Copyright © 2021 Elsevier Inc.

Objective: The area of pediatric hypertension (HTN) research has seen substantial progress over the last two decades, but no bibliometric analysis has yet been undertaken to describe these advances. This study aims to describe the published research examining HTN in children and adolescents from 2000 to 2018., Methods: Articles were retrieved using PubMed and the Web of Science. Analyses were performed to quantify the evolution of scientific output, identifying the leading journals, authors, and countries as well as the existing collaboration networks. Likewise, we identified the most cited articles, describing their document type, main topic focus, and the age of the patients studied., Results: In total, we identified 8317 articles in the Web of Science. The annual number of publications doubled over the study period. Articles were published in 1415 journals, mainly in the categories of Peripheral & Vascular Diseases and Pediatrics. The USA dominated scientific production in the field. Regarding researcher productivity, the top 202 authors participated in 20% of the articles, and there were 47 stable research clusters, with the largest component made up of 17 authors. Altogether, there were 145 most cited articles, with an irregular annual distribution; about half focus on HTN itself, while the rest study associated disorders and conditions., Conclusion: This is the first study to analyze scientific output on HTN in children and adolescents. The snapshot that emerges is of a research area that is growing but is still in a relatively early phase of development., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)
