RESUMEN

Postnatal hippocampal neurogenesis is essential for learning and memory. Hippocampal neural precursor cells (NPCs) can be induced to proliferate and differentiate into either glial cells or dentate granule cells. Notably, hippocampal neurogenesis decreases dramatically with age, partly due to a reduction in the NPC pool and a decrease in their proliferative activity. Alpha-melanocyte-stimulating hormone (α-MSH) improves learning, memory, neuronal survival and plasticity. Here, we used postnatally-isolated hippocampal NPCs from Wistar rat pups (male and female combined) to determine the role of the melanocortin analog [Nle4, D-Phe7]-α-MSH (NDP-MSH) in proliferation and fate acquisition of NPCs. Incubation of growth-factor deprived NPCs with 10 nM NDP-MSH for 6 days increased the proportion of Ki-67- and 5-bromo-2'-deoxyuridine (BrdU)-positive cells, compared to the control group, and these effects were blocked by the MC4R antagonist JKC-363. NDP-MSH also increased the proportion of glial fibrillar acidic protein (GFAP)/Ki-67, GFAP/sex-determining region Y-box2 (SOX2) and neuroepithelial stem cell protein (NESTIN)/Ki-67-double positive cells (type-1 and type-2 precursors). Finally, NDP-MSH induced peroxisome proliferator-activated receptor (PPAR)-γ protein expression, and co-incubation with the PPAR-γ inhibitor GW9662 prevented the effect of NDP-MSH on NPC proliferation and differentiation. Our results indicate that in vitro activation of MC4R in growth-factor-deprived postnatal hippocampal NPCs induces proliferation and promotes the relative expansion of the type-1 and type-2 NPC pool through a PPAR-γ-dependent mechanism. These results shed new light on the mechanisms underlying the beneficial effects of melanocortins in hippocampal plasticity and provide evidence linking the MC4R and PPAR-γ pathways in modulation of hippocampal NPC proliferation and differentiation.

RESUMEN

Chemsex is described as the use of psychoactive substances during sexual activity to sustain, enhance, disinhibit, or facilitate the sexual experience. It preferentially concerns men who have sex with men. The main objective of this study was to examine the relationship between participation in chemsex and the psychological variables impulsivity, sexual assertiveness, and hypersexuality. The sample was composed of 137 Spanish men. A total of 104 participants reported that they had engaged in chemsex, with ages ranging from 19 to 42 years (M = 31.41, SD = 4.83). A total of 33 participants reported that they had never participated in chemsex sessions. The participants were contacted and recruited at social centers, LGBT associations, and key informants. Results showed that men who participated in chemsex reported higher impulsivity, higher hypersexuality, and lower sexual assertiveness than those who have never participated in it. The frequency of participation in chemsex, as well as the number of substances consumed, was positively and significantly correlated with dimensions of impulsivity and hypersexuality. This frequency and this consumption were negatively and significantly correlated with sexual assertiveness. Findings showed significant differences in the psychological variables based on the number of consumed substances (polydrug use/consumption of one substance) and the time of consumption (before, during or before and during sex). In conclusion, the study demonstrates the existence of a clear relationship between the experience of chemsex and psychological factors such as being an impulsive person, presenting hypersexual behavior, and/or having low sexual assertiveness.

RESUMEN

Varroa mites, scientifically identified as Varroa destructor, pose a significant threat to beekeeping and cause one of the most destructive diseases affecting honey bee populations. These parasites attach to bees, feeding on their fat tissue, weakening their immune systems, reducing their lifespans, and even causing colony collapse. They also feed during the pre-imaginal stages of the honey bee in brood cells. Given the critical role of honey bees in pollination and the global food supply, controlling Varroa mites is imperative. One of the most common methods used to evaluate the level of Varroa mite infestation in a bee colony is to count all the mites that fall onto sticky boards placed at the bottom of a colony. However, this is usually a manual process that takes a considerable amount of time. This work proposes a deep learning approach for locating and counting Varroa mites using images of the sticky boards taken by smartphone cameras. To this end, a new realistic dataset has been built: it includes images containing numerous artifacts and blurred parts, which makes the task challenging. After testing various architectures (mainly based on two-stage detectors with feature pyramid networks), combination of hyperparameters and some image enhancement techniques, we have obtained a system that achieves a mean average precision (mAP) metric of 0.9073 on the validation set.

RESUMEN

Blackleg and soft rot diseases represent a major threat to the health of potato (Solanum tuberosum) and other vegetable, ornamental and fruit crops worldwide; their main causal agents are species of Pectobacterium and Dickeya. In May 2022, 60% of potato plants (cv. Spunta) in a production field in Córdoba, Argentina (31°32'36''S 64°09'46''W) showed soft rot, blackleg and wilt. To isolate the causal agent, decayed plant tissues were disinfected in 2% NaClO, macerated in sterile water and streaked on crystal violet pectate (CVP) medium. Plates were incubated at 28°C for 48 h. Colonies that produced a pit on CVP medium were purified on nutrient agar. Two of the isolates, called 1Aia and 1B, were characterized by tests commonly employed for the identification of pectinolytic bacteria (Schaad et al. 2001). Both produced Gram-negative rods that were facultatively anaerobic, oxidase negative, nonfluorescent on King´s B, resistant to erythromycin and caused soft rot of potato slices. In addition, these isolates did not produce the blue pigment indigoidine and grew on nutrient glucose agar containing 5% NaCl. Phenotypic characteristics of the isolates 1Aia and 1B were compatible with Pectobacterium spp. Genomic DNA was extracted using the commercially available Wizard® Genomic DNA Purification Kit (Promega) according to the manufacturer's instructions for the purification of DNA from Gram-negative bacteria. The isolates were positive in a PCR assay for Pectobacterium brasiliense (Duarte et al. 2004). The purified DNA of isolate 1Aia was used to construct a pooled Illumina library, which was sequenced at the Genomics Unit from the National Institute of Agricultural Technology (INTA, Argentina), by using high-throughput Illumina sequencing technology. Average nucleotide identity (ANI) calculation performed by FastANI v0.1.3 (Jain et al. 2018) showed 96.11% identity between the genome of the type strain LMG 21371 of P. brasiliense (Acc. no. JQOE00000000) and our strain 1Aia (Acc. no. JAYGXQ000000000). For pathogenicity test, 3-weeks-old potato plants (cv. Spunta) planted in pots were infiltrated with 10 µl of a bacterial suspension (1x107 CFU/ml) 5 cm above the base of the stem using a sterile syringe. Negative controls were infiltrated with sterile water. Plants were kept under greenhouse conditions and regularly watered. The experiment was performed twice with six plants per treatment. Two days after inoculation, plants treated with P. brasiliense strain 1Aia or 1B showed necrotic lesions on the stems and tubers soft rot symptoms while control plants remained asymptomatic. To fulfill Koch´s postulates, bacteria were re-isolated from symptomatic plants. Re-isolated bacteria, called 1Aia d and 1B d, were confirmed as P. brasiliense according to biochemical and PCR results, as outlined above. Also, the % ANI value between P. brasiliense isolates 1Aia and 1Aia d was 99.99% (Acc. no. JAYGXR000000000). To our knowledge, this is the first report of the occurrence of P. brasiliense in Argentina. This pathogen has been observed causing blackleg and tuber soft rot on potato in Brazil (Duarte et al. 2004), Netherlands (Nunes Leite et al. 2014), Switzerland (de Werra et al. 2015), Russia (Voronina et al. 2019), Serbia (Loc et al. 2022) and USA (Zhang et al. 2023), among other countries worldwide. Due to the important economic and nutritional value of the crop, the distribution of P. brasiliense needs to be investigated and monitored in order to develop effective control strategies.

RESUMEN

The TMEM16A channel, a member of the TMEM16 protein family comprising chloride (Cl-) channels and lipid scramblases, is activated by the free intracellular Ca2+ increments produced by inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release after GqPCRs or Ca2+ entry through cationic channels. It is a ubiquitous transmembrane protein that participates in multiple physiological functions essential to mammals' lives. TMEM16A structure contains two identical 10-segment monomers joined at their transmembrane segment 10. Each monomer harbours one independent hourglass-shaped pore gated by Ca2+ ligation to an orthosteric site adjacent to the pore and controlled by two gates. The orthosteric site is created by assembling negatively charged glutamate side chains near the pore´s cytosolic end. When empty, this site generates an electrostatic barrier that controls channel rectification. In addition, an isoleucine-triad forms a hydrophobic gate at the boundary of the cytosolic vestibule and the inner side of the neck. When the cytosolic Ca2+ rises, one or two Ca2+ ions bind to the orthosteric site in a voltage (V)-dependent manner, thus neutralising the electrostatic barrier and triggering an allosteric gating mechanism propagating via transmembrane segment 6 to the hydrophobic gate. These coordinated events lead to pore opening, allowing the Cl- flux to ensure the physiological response. The Ca2+-dependent function of TMEM16A is highly regulated. Anions with higher permeability than Cl- facilitate V dependence by increasing the Ca2+ sensitivity, intracellular protons can replace Ca2+ and induce channel opening, and phosphatidylinositol 4,5-bisphosphate bound to four cytosolic sites likely maintains Ca2+ sensitivity. Additional regulation is afforded by cytosolic proteins, most likely by phosphorylation and protein-protein interaction mechanisms.

RESUMEN

Background and aims Patients’ perception of their bowel cleansing quality may guide rescue cleansing strategies before colonoscopy. The main aim of this study was to train and validate a convolutional neural network (CNN) for classifying rectal effluent during bowel preparation intake as “adequate” or “inadequate” cleansing before colonoscopy.Patients and methodsPatients referred for outpatient colonoscopy were asked to provide images of their rectal effluent during the bowel preparation process. The images were categorized as adequate or inadequate cleansing based on a predefined 4-picture quality scale. A total of 1203 images were collected from 660 patients. The initial dataset (799 images), was split into a training set (80%) and a validation set (20%). The second dataset (404 images) was used to develop a second test of the CNN accuracy. Afterward, CNN prediction was prospectively compared with the Boston Bowel Preparation Scale (BBPS) in 200 additional patients who provided a picture of their last rectal effluent.ResultsOn the initial dataset, a global accuracy of 97.49%, a sensitivity of 98.17% and a specificity of 96.66% were obtained using the CNN model. On the second dataset, an accuracy of 95%, a sensitivity of 99.60% and a specificity of 87.41% were obtained. The results from the CNN model were significantly associated with those from the BBPS (P<0.001), and 77.78% of the patients with poor bowel preparation were correctly classified.ConclusionThe designed CNN is capable of classifying “adequate cleansing” and “inadequate cleansing” images with high accuracy.

RESUMEN

BACKGROUND: Current research is moving from studying cognitive biases and maladaptive emotion regulation (ER) as relatively stable phenomena contributing to affective disturbances, adopting ecological methodologies, such as Experience Sampling Methods (ESM). However, there is still limited ESM evidence on the interactions between stress and ER strategies' use, and negative interpretation biases, regarding their relations with momentary affective states. In this study, we used a new ESM design to disentangle the contextual, regulatory and cognitive processes implicated in daily affective experiences. METHOD: A sample of 103 participants completed an ESM study (3 times a day for 10 days) that included self-reports of momentary affect, stress intensity, ER strategies' use and a cognitive task measuring momentary negative interpretation biases. RESULTS: Multilevel analyses supported significant interactions of both rumination and worry with stress intensity, to account for momentary higher negative and lower positive affect levels. Furthermore, higher state negative interpretation bias levels uniquely predicted both higher negative and lower positive momentary affect levels. CONCLUSION: This study implemented a novel online cognitive task within an ESM procedure, which helped to disentangle how contextual ER strategies' use and momentary cognitive biases uniquely relate to affective experiences in daily life.

RESUMEN

Acute myocardial infarction can result in various mechanical complications, although they have become rare with the advent of reperfusion therapies. Among these complications, ventricular septal rupture (VSR) and left ventricular aneurysm (LVA) are infrequent but life-threatening conditions associated with high morbidity and mortality. We present a rare case of a 67-year-old male with acute myocardial infarction who developed concomitant apical LVA and ventricular septal rupture. LEARNING POINTS: Mechanical complications of myocardial infarction, such as a ventricular septal rupture (VSR) and left ventricular aneurysm (LVA), are rare but life-threatening.Early diagnosis is critical. A ventricular septal defect (VSD) requires immediate surgical closure, while surgery for LVA is only considered in specific cases such as chest pain or thromboembolism.Diagnostic tools such as echocardiography and left ventriculography play a vital role in identifying and characterising these complications, enabling timely treatment decisions.

RESUMEN

BACKGROUND: Mitogen-activated protein kinases (MAPKs) preserve cell homeostasis by transducing physicochemical fluctuations of the environment into multiple adaptive responses. These responses involve transcriptional rewiring and the regulation of cell cycle transitions, among others. However, how stress conditions impinge mitotic progression is largely unknown. The mitotic checkpoint is a surveillance mechanism that inhibits mitotic exit in situations of defective chromosome capture, thus preventing the generation of aneuploidies. In this study, we investigate the role of MAPK Pmk1 in the regulation of mitotic exit upon stress. RESULTS: We show that Schizosaccharomyces pombe cells lacking Pmk1, the MAP kinase effector of the cell integrity pathway (CIP), are hypersensitive to microtubule damage and defective in maintaining a metaphase arrest. Epistasis analysis suggests that Pmk1 is involved in maintaining spindle assembly checkpoint (SAC) signaling, and its deletion is additive to the lack of core SAC components such as Mad2 and Mad3. Strikingly, pmk1Δ cells show up to twofold increased levels of the anaphase-promoting complex (APC/C) activator Cdc20Slp1 during unperturbed growth. We demonstrate that Pmk1 physically interacts with Cdc20Slp1 N-terminus through a canonical MAPK docking site. Most important, the Cdc20Slp1 pool is rapidly degraded in stressed cells undergoing mitosis through a mechanism that requires MAPK activity, Mad3, and the proteasome, thus resulting in a delayed mitotic exit. CONCLUSIONS: Our data reveal a novel function of MAPK in preventing mitotic exit and activation of cytokinesis in response to stress. The regulation of Cdc20Slp1 turnover by MAPK Pmk1 provides a key mechanism by which the timing of mitotic exit can be adjusted relative to environmental conditions.

RESUMEN

Prader-Willi Syndrome (PWS) is the most common genetic cause of obesity, occurring in approximately 1 in 15,000 newborns. It results from the lack of expression of genes on the paternal allele of the chromosomal region 15q-11q13 (65-75% due to type 1 or type 2 deletion). Individuals with PWS experience associated symptoms such as hypotonia, hyperphagia, and early-onset obesity (before 5 years of age). Around 20% of adults with PWS also develop type 2 diabetes. Previous studies have shown the beneficial effects of GLP1-RA medications, such as exenatide and liraglutide, in treating type 2 diabetes in PWS. However, there is limited information available on the use of semaglutide in PWS. This study aimed to evaluate the effects of semaglutide on weight loss and glycaemic control in four patients with PWS and type 2 diabetes associated with obesity. The patients were started on weekly subcutaneous progressive doses of semaglutide.

RESUMEN

(1) Background: Interparental conflict is a phenomenon that poses a serious threat not only to the quality of life of the couple but also to the father-child relationship, mother-child relationship, and well-being of adolescents. This study examined the difference in parental attachment and adjustment in adolescents exposed to marital conflict versus those not exposed to parental conflicts in low-income areas. (2) Methods: 67 adolescents involved in Child Welfare Services (CWS) in disadvantaged neighbourhoods in southern Spain were examined. The sample was split into two groups according to the exposure to marital conflict. Subsequently, differences between groups were analysed on father attachment, mother attachment, aggression, antisocial behaviour, and emotional intelligence. (3) Results: Primarily, the data showed significantly worse attachment with the father among conflict-exposed versus non-conflict-exposed adolescents. These results were not found for the attachment with the mother. Additionally, greater anger and worse stress management were found in conflict-exposed adolescents. (4) Conclusions: The results partially confirmed the spillover and compensatory hypothesis. Practical implications point out that developing preventive interventions that protect the father-adolescent attachment in situations of family conflict is recommended.

RESUMEN

Decreased levels of positive affect (PA) are a hallmark of depression. Current models propose as potential main mechanisms a dysfunctional use of emotion regulation (ER) strategies (i.e. dampening, positive rumination), and a maladaptive activation of pro-hedonic goals. However, the role of these mechanisms in PA in daily life remains understudied. We used a 10-day ESM design to assess how these mechanisms influence each other and contribute to depressive symptomatology-related low momentary PA in 139 individuals. Higher depressive symptoms were associated with lower PA, pro-hedonic goals, more frequent use of positive rumination, and higher use of dampening. Further, experiencing higher levels of PA predicted lower following time point use of dampening in individuals with higher symptoms. Finally, using positive rumination was more beneficial (i.e. predicted higher PA increases one moment later) for individuals with higher symptomatology. Our findings suggest that moment-to-moment changes in PA daily life are affected by, and have an effect on, both pro-hedonic goals and the use of dampening and positive rumination, highlighting specific cognitive-affective mechanisms that should be considered when designing interventions aimed at improving low PA characterising depression symptomatology.

RESUMEN

BACKGROUND: Physical inactivity during pregnancy has been shown to be linked to an increased risk of complications. However, during pregnancy, doubts arise about what type, intensity and frequency of physical activity are most recommended. OBJECTIVE: Our main objective was to know the level of physical activity (PA) and sedentary lifestyle in a representative sample of pregnant women in Málaga, one of the most populated cities in Spain. Also, we aimed to find out the effects of PA on obstetric and perinatal outcomes and on the mental health of pregnant women, differentiated according to PA intensity and domain. METHODS: Five hundred and forty full-term pregnant women who had their obstetric checks in the maternity ward of the Regional University Hospital of Málaga were recruited through consecutive sampling. Participants answered a questionnaire that included the WHO Global Physical Activity Questionnaire (GPAQ), the Edinburgh Depression Scale (EDS), the Generalized Anxiety Disorder Scale (GAD-7) and some other sociodemographic and health-related questions. Subsequently, information about perinatal outcomes was obtained after birth. RESULTS: Only 50.8% of women followed the WHO recommendations on activity. We found a high proportion of obese pregnant women and a direct effect of a sedentary lifestyle on the rate of cesarean sections and vulvovaginal tears in spontaneous births, as well as on the mental health of future mothers. Women's age, the number of children, BMI at the beginning of pregnancy and leisure time physical activity (LTPA) explained anxiety scores, and age, LTPA, BMI at the end of pregnancy and intense work-related physical activity (WTPA) predicted depression scores. CONCLUSIONS: LTPA improves obstetric outcomes, helping to reduce the rate of cesarean sections and vulvovaginal tears, as well as reducing prenatal anxiety and depression.

RESUMEN

Novel approaches in higher education are needed to reverse underrepresentation of racial/ethnic groups in science, technology, engineering, mathematics, and medicine (STEMM). Building on theoretical frameworks for practice in diverse learning environments, this study provides evidence for Inclusive Science as a conceptual model that reflects initiatives intended to diversify biomedical research training for undergraduates. Using multiple case study design and cross-case analysis, we analyzed data from 10 higher education sites that were awarded the Building Infrastructure Leading to Diversity (BUILD) grant funded by the National Institutes of Health (NIH). We identified the following dimensions of the Inclusive Science model: promoting participation of diverse researchers; introducing diversity innovations in science and research curriculum; improving campus climate for diversity; providing tangible institutional support; creating partnerships with diverse communities; and integrating students' social identities with science identity. We illustrate each dimension of the model with examples of campus practices across BUILD sites. While many may doubt that science can be responsive to diversity, the interventions developed by these campuses illustrate how colleges and universities can actively engage in culturally responsive practices in STEMM undergraduate training that integrate trainees' identities, knowledge of diverse communities, and create a greater awareness of the climate for diversity that affects student training and outcomes. Implications include culturally responsive strategies that many more higher education institutions can employ to support scientific career training for historically excluded groups.

RESUMEN

One of the most frequent diffuse interstitial lung diseases is hypersensitivity pneumonitis. It is related to exposure to diverse antigens, causing fibrosis in advanced stages, making the differential diagnosis with interstitial pulmonary fibrosis difficult as it overlaps with the usual interstitial pneumonia pattern. On the other hand, there are interstitial lung diseases associated with ANCA, such as microscopic polyangiitis, which is also related to the usual interstitial pneumonia pattern. We present the case of a 74-year-old male patient with chronic dyspnea, history of smoking and exposure to organic particles, in addition to a pattern suggestive of moderately severe restriction. The diagnosis was confirmed by histology of hypersensitivity pneumonitis by presenting granules, however, anti MPO and p-ANCA positivity was found, integrating the simultaneous diagnosis of microscopic polyangiitis. This is a case of difficult diagnosis since these pathologies have not been previously reported to coexist.

RESULTS: The system includes 86.9% of all sterile preparations prepared in the Hospital Pharmacy, encompassing chemotherapy, adult parenteral nutrition, and other non-hazardous sterile preparations. Furthermore, the application has been implemented in all hospitalization wards, day care units and two external sites. On average, 5,403 preparations were tracked per month (SD = 297.3). The time required to address incidents related to the distribution of preparations has decreased by 83% (from 38.9 to 6.6 minutes per day). The App regularly provides valuable management data for optimizing workflow in the compounding area. Additionally, users have expressed satisfaction with the application. DISCUSION: The proposed application enables hospital staff to easily and intuitively track preparations compounded in the pharmacy, irrespective of the computer program used for prescription. It has significantly reduced the need for manual record-keeping and has mitigated incidents associated with the distribution of sterile preparations.

RESUMEN

INTRODUCTION: The primary objective of this study is to describe the design and implementation of a mobile application (App) for tracking preparations compounded in the Pharmacy Department. Secondary objectives include: i) evaluating the time spent on resolving incidents related to the distribution of preparations before and after implementation, ii) assessing users satisfaction with the application, and iii) establishing a panel of quality indicators based on the data extracted from the App. METHODS: 1) Defining application requirements, identifying drugs to be included in the software and outlining different workflows. 2) Developing the App in collaboration with the supplier and integrating it with the computer programs involved in prescription and validation. Additionally, QR codes were created to identify delivery points at destination units, and suitable mobile devices were acquired. The initial phase involved user training in the application and a pilot test conducted in a hospital ward. 3) The subsequent phase focused on expansion and consolidation. RESULTS: The system includes 86.9% of all sterile preparations prepared in the Hospital Pharmacy, encompassing chemotherapy, adult parenteral nutrition, and other non-hazardous sterile preparations. Furthermore, the application has been implemented in all hospitalisation wards, day care units and two external sites. On average, 5403 preparations were tracked per month (SD = 297.3). The time required to address incidents related to the distribution of preparations has decreased by 83% (from 38.9 to 6.6 min per day). The App regularly provides valuable management data for optimising workflow in the compounding area. Additionally, users have expressed satisfaction with the application. DISCUSION: The proposed application enables hospital staff to easily and intuitively track preparations compounded in the Pharmacy, irrespective of the computer program used for prescription. It has significantly reduced the need for manual record-keeping and has mitigated incidents associated with the distribution of sterile preparations.

RESUMEN

BACKGROUND AND AIMS: Patients' perception of their bowel cleansing quality may guide rescue cleansing strategies before colonoscopy. The main aim of this study was to train and validate a convolutional neural network (CNN) for classifying rectal effluent during bowel preparation intake as "adequate" or "inadequate" cleansing before colonoscopy. PATIENTS AND METHODS: Patients referred for outpatient colonoscopy were asked to provide images of their rectal effluent during the bowel preparation process. The images were categorized as adequate or inadequate cleansing based on a predefined 4-picture quality scale. A total of 1203 images were collected from 660 patients. The initial dataset (799 images), was split into a training set (80%) and a validation set (20%). The second dataset (404 images) was used to develop a second test of the CNN accuracy. Afterward, CNN prediction was prospectively compared with the Boston Bowel Preparation Scale (BBPS) in 200 additional patients who provided a picture of their last rectal effluent. RESULTS: On the initial dataset, a global accuracy of 97.49%, a sensitivity of 98.17% and a specificity of 96.66% were obtained using the CNN model. On the second dataset, an accuracy of 95%, a sensitivity of 99.60% and a specificity of 87.41% were obtained. The results from the CNN model were significantly associated with those from the BBPS (P<0.001), and 77.78% of the patients with poor bowel preparation were correctly classified. CONCLUSION: The designed CNN is capable of classifying "adequate cleansing" and "inadequate cleansing" images with high accuracy.
