RESUMEN

The prevalence of mental health problems constitutes an open challenge for modern societies, particularly for low and middle-income countries with wide gaps in mental health support. With this in mind, five datasets were analyzed to track mental health trends in Mexico City during the pandemic's first year. This included 33,234 responses to an online mental health risk questionnaire, 349,202 emergency calls, and city epidemiological, mobility, and online trend data. The COVID-19 mental health risk questionnaire collects information on socioeconomic status, health conditions, bereavement, lockdown status, and symptoms of acute stress, sadness, avoidance, distancing, anger, and anxiety, along with binge drinking and abuse experiences. The lifeline service dataset includes daily call statistics, such as total, connected, and abandoned calls, average quit time, wait time, and call duration. Epidemiological, mobility, and trend data provide a daily overview of the city's situation. The integration of the datasets, as well as the preprocessing, optimization, and machine learning algorithms applied to them, evidence the usefulness of a combined analytic approach and the high reuse potential of the data set, particularly as a machine learning training set for evaluating and predicting anxiety, depression, and post-traumatic stress disorder, as well as general psychological support needs and possible system loads.

RESUMEN

Introduction: Pediatricians in training are a population at risk for anxiety and depression: they face long working hours, they are confronted with the suffering and death of a vulnerable population and may have personal characteristics that put them in danger. Nonetheless, few studies have looked at their prevalence and associated factors. We aimed to compare demographic, professional activities, adversities and perfectionism personality features between a group of pediatricians in training with depression and/or anxiety and a group of pediatricians in training without depression nor anxiety and, to identify the variables that increase the probabilities of depression and/or anxiety in pediatricians in training. Methods: Pediatric residents who voluntarily answered an online survey distributed via personal and institutional social media channels from October 2019 to April 2021, as part of a cross-sectional study with medical specialists and residents from Mexico were included. Demographic information, professional activities and adversities, perfectionism personality features (Multidimensional Perfectionism Scale), depression and anxiety (ICD-11 PHC) were evaluated. For comparison purposes Chi-square tests (χ2) and independent sample t-tests were used. A logistic regression analysis was used to identify those variables that increase the probabilities of depression and/or anxiety. Results: 934 pediatric residents answered the survey. 11.6% reported having depression and 20% anxiety. Being single, a history of anxious or depressive episodes, being the resident in charge of a patient who died, aggressions from colleagues and a high concern for errors were associated with current depression and/or anxiety. Discussion: Screening for depressive and anxious symptoms should be routinely performed from entry to the residency to favor early intervention. A shift from promoting perfectionism to a more compassionate training could serve a population facing so many adversities.

RESUMEN

Rod-shaped fission yeast grows through cell wall expansion at poles and septum, synthesized by essential glucan synthases. Bgs1 synthesizes the linear ß(1,3)glucan of primary septum at cytokinesis. Linear ß(1,3)glucan is also present in the wall poles, suggesting additional Bgs1 roles in growth polarity. Our study reveals an essential collaboration between Bgs1 and Tea1-Tea4, but not other polarity factors, in controlling growth polarity. Simultaneous absence of Bgs1 function and Tea1-Tea4 causes complete loss of growth polarity, spread of other glucan synthases, and spherical cell formation, indicating this defect is specifically due to linear ß(1,3)glucan absence. Furthermore, linear ß(1,3)glucan absence induces actin patches delocalization and sterols spread, which are ultimately responsible for the growth polarity loss without Tea1-Tea4. This suggests strong similarities in Bgs1 functions controlling actin structures during cytokinesis and polarized growth. Collectively, our findings unveil that cell wall ß(1,3)glucan regulates polarized growth, like the equivalent extracellular matrix in neuronal cells.

RESUMEN

Obesity is a major health challenge due to its high prevalence and associated comorbidities. The excessive intake of a diet rich in fat and sugars leads to a persistent imbalance between energy intake and energy expenditure, which increases adiposity. Here, we provide an update on relevant diet-microbe-host interactions contributing to or protecting from obesity. In particular, we focus on how unhealthy diets shape the gut microbiota and thus impact crucial intestinal neuroendocrine and immune system functions. We describe how these interactions promote dysfunction in gut-to-brain neuroendocrine pathways involved in food intake control and postprandial metabolism and elevate the intestinal proinflammatory tone, promoting obesity and metabolic complications. In addition, we provide examples of how this knowledge may inspire microbiome-based interventions, such as fecal microbiota transplants, probiotics, and biotherapeutics, to effectively combat obesity-related disorders. We also discuss the current limitations and gaps in knowledge of gut microbiota research in obesity.

RESUMEN

BACKGROUND: ARCADIA compared apixaban to aspirin for secondary stroke prevention in patients with cryptogenic stroke and atrial cardiopathy. One possible explanation for the neutral result is that biomarkers used did not optimally identify atrial cardiopathy. We examined the relationship between biomarker levels and subsequent detection of AF, the hallmark of atrial cardiopathy. METHODS: Patients were randomized if they met criteria for atrial cardiopathy, defined as P-wave terminal force >5000 µV*ms in ECG lead V1 (PTFV1), NT-proBNP >250 pg/mL, or left atrial diameter index (LADI) ⩾3 cm/m2. For this analysis, the outcome was AF detected per routine care. RESULTS: Of 3745 patients who consented to screening for atrial cardiopathy, 254 were subsequently diagnosed with AF; 96 before they could be randomized and 158 after randomization. In unadjusted analyses, ln(NT-proBNP) (RR per SD, 1.99; 95% CI, 1.85-2.13), PTFV1 (RR per SD, 1.15; 95% CI, 1.03-1.28) and LADI (RR per SD, 1.34; 95% CI, 1.20-1.50) were associated with AF. In a model containing all 3 biomarkers, demographics, and AF risk factors, age (RR per 10 years, 1.24; 95% CI, 1.09-1.41), ln(NT-proBNP) (RR per SD, 1.88; 95% CI, 1.67-2.11) and LADI (RR per SD, 1.25; 95% CI, 1.14-1.37) were associated with AF. These three variables together had a c-statistic of 0.82 (95% CI, 0.79-0.85) but only modest calibration. Discrimination was attenuated in sensitivity analyses of patients eligible for randomization who may have been more closely followed for AF. CONCLUSIONS: Biomarkers used to identify atrial cardiopathy in ARCADIA were moderately predictive of subsequent AF.

RESUMEN

OBJECTIVE: The aim of the study was to describe how physical exercise affects metabolic control, insulin requirements and carbohydrate intake in children who use hybrid closed-loop systems. METHODS: Cross-sectional study design. The sample included 21 children and adolescents diagnosed with type 1 diabetes. During the study, participants were monitored for a period of 7 days to gather comprehensive data on these factors. RESULTS: Nine participants (42.9%) had switched to exercise mode to raise the target glucose temporarily to 150 mg/dL. The HbA1c values ranged from 5.5% to 7.9% (median, 6.5%; IQR, 0.75). The percentage of time within the target range of 70-180 mg/dL was similar; however, there was an increased duration of hyperglycaemia and more autocorrections on exercise days. The time spent in severe hyperglycaemia (>250 mg/dL) increased by 2.7% in exercise compared to non-exercise days (P = .02). It is worth noting that hypoglycaemic episodes did not increase during the exercise days compared with non-exercise days. CONCLUSION: The hybrid closed-loop system was effective and safe in children and adolescents with type 1 diabetes during the performance of competitive sports in real life.

RESUMEN

BACKGROUND: The gut microbiota controls broad aspects of human metabolism and feeding behavior, but the basis for this control remains largely unclear. Given the key role of human dipeptidyl peptidase 4 (DPP4) in host metabolism, we investigate whether microbiota DPP4-like counterparts perform the same function. RESULTS: We identify novel functional homologs of human DPP4 in several bacterial species inhabiting the human gut, and specific associations between Parabacteroides and Porphyromonas DPP4-like genes and type 2 diabetes (T2D). We also find that the DPP4-like enzyme from the gut symbiont Parabacteroides merdae mimics the proteolytic activity of the human enzyme on peptide YY, neuropeptide Y, gastric inhibitory polypeptide (GIP), and glucagon-like peptide 1 (GLP-1) hormones in vitro. Importantly, administration of E. coli overexpressing the P. merdae DPP4-like enzyme to lipopolysaccharide-treated mice with impaired gut barrier function reduces active GIP and GLP-1 levels, which is attributed to increased DPP4 activity in the portal circulation and the cecal content. Finally, we observe that linagliptin, saxagliptin, sitagliptin, and vildagliptin, antidiabetic drugs with DPP4 inhibitory activity, differentially inhibit the activity of the DPP4-like enzyme from P. merdae. CONCLUSIONS: Our findings confirm that proteolytic enzymes produced by the gut microbiota are likely to contribute to the glucose metabolic dysfunction that underlies T2D by inactivating incretins, which might inspire the development of improved antidiabetic therapies.

RESUMEN

BACKGROUND: We assessed pain, acceptability, patient preference, and tolerability of patients with psoriasis and psoriatic arthritis after switching guselkumab from a prefilled syringe to One-Press autoinjector pen. METHODS: Patients with psoriasis and psoriatic arthritis treated for at least 6 months with guselkumab syringe were recruited from Jan 2019 to Dec 2022. Gender, age, diagnosis, self-administration, and pain perception of guselkumab prefilled syringe were recorded. At the first visit, patients completed a post-auto-injection syringe questionnaire before starting auto-injection pen administration. After 2 and 6 months of guselkumab self-injection using the One-Press autoinjector pen, patient experience, adherence, preference, pain, and safety of each administration were assessed using post-guselkumab by One-Press autoinjector pen questionnaire. RESULTS: 40 patients [psoriasis n=34, psoriatic arthritis n=6] were included. All patients self-administered guselkumab by One-Press autoinjector pen. Pain at the injection site was significantly reduced with the use of the One-Press autoinjector pen. All patients considered that using One-Press autoinjector pen was easier than the syringe, 98% chose the pen as their preferred delivery system. CONCLUSION: The One-Press autoinjector pen for guselkumab administration is presented as a preferred option, with a high satisfaction and less painful compared to the administration of guselkumab in a prefilled syringe.

RESUMEN

In this original research, we present the results in terms of effectiveness and safety of bimekizumab for hidradenitis suppurativa in real clinical practice. Results indicated significant improvement in all activity scores and patient-reported outcomes at week 16, including a notable decrease in mean IHS4 from 27.1 to 15.6 (p < 0.001), HS-PGA from 5.1 to 3.2 (p < 0.001), VAS pain from 8.3 to 4.7 (p < 0.001) and DLQI from 21.6 to 12.6 (p < 0.001). Bimekizumab, administered every 2 or 4 weeks, was well-tolerated with no discontinuations and no new safety concerns identified. These findings corroborate the drug's effectiveness and favourable safety profile observed in phase 3 clinical trials, supporting its use in real-world clinical practice for treating HS.

RESUMEN

Background This study was designed to analyze the influence of age and comprehensive geriatric evaluation on clinical results of pancreaticobiliary disease management in elderly patients. Methods A prospective observational study has been undertaken, including 140 elderly patients (over 75 years) with benign pancreaticobiliary disease. Patients were divided according to age in the following groups: group 1: 75–79 years old; group 2: 80–84 years old; group 3: 85 years and older. They underwent a comprehensive geriatric assessment with different scales: Barthel Index, Pfeiffer Index, Charlson Index, and Fragility scale, at admission and had been follow-up 90 days after hospital discharge to analyze its influence on morbidity and mortality. Results Overall, 140 patients have been included (group 1=51; group 2=43 and group 3=46). Most of them, 52 cases (37.8%), had acute cholecystitis, followed by 29 cases of acute cholangitis (20.2%) and acute pancreatitis with 25 cases (17.9%). Significant differences has been observed on complications in different age groups (p=0.033). Especially in patients with a Barthel Index result ≤60, which suggests that these less functional patients had more severe complications after their treatment (p=0.037). The mortality rate was 7.1% (10 patients). Conclusions No significant differences were found between age, morbidity and mortality in elderly patients with pancreaticobiliary disease. Comprehensive geriatric scales showed some utility in their association with specific complications. (AU)


Antecedentes Este estudio fue diseñado para analizar la influencia de la edad y la evaluación geriátrica integral en los resultados clínicos del manejo de la enfermedad pancreatobiliar en pacientes de edad avanzada. Métodos Se ha realizado un estudio observacional prospectivo en el que se incluyeron 140 pacientes de edad avanzada (mayores de 75 años) con enfermedad pancreatobiliar benigna. Los pacientes se dividieron según la edad en los siguientes grupos: Grupo 1: 75-79 años; Grupo 2: 80-84 años; Grupo 3: 85 años y más. Se les realizó una valoración geriátrica integral con diferentes escalas: Barthel Index, Pfeiffer Index, Charlson Index y Fragility scale, al ingreso y seguimiento 90 días después del alta hospitalaria para analizar su influencia en la morbimortalidad. Resultados En total, se incluyeron 140 pacientes (Grupo 1=51; Grupo 2=43 y Grupo 3=46). La mayoría de ellos, 52 casos (37,8%), presentaron colecistitis aguda, seguido de colangitis aguda con 29 casos (20,2%) y pancreatitis aguda con 25 casos (17,9%). Se han observado diferencias significativas en las complicaciones en diferentes grupos de edad (p=0,033). Especialmente en pacientes con un índice de Barthel ≤60, lo que sugiere que estos pacientes menos funcionales tuvieron complicaciones más severas después de su tratamiento (p=0,037). La tasa de mortalidad fue de 7,1% (10 pacientes). Conclusiones No se encontraron diferencias significativas entre la edad, la morbilidad y la mortalidad en pacientes ancianos con enfermedad pancreatobiliar. Las escalas geriátricas integrales mostraron cierta utilidad en su asociación con complicaciones específicas. (AU)

RESUMEN

We are entering a new era in the management of adiposity-based chronic disease (ABCD) with type 2 diabetes (T2D) and related chronic kidney disease (CKD). ABCD, T2D and CKD can affect almost every major organ system and have a particularly strong impact on the incidence of cardiovascular disease (CVD) and heart failure. ABCD and the associated insulin resistance are at the root of many cardiovascular, renal and metabolic (CKM) disorders, thus an integrated therapeutic framework using weight loss (WL) as a disease-modifying intervention could simplify the therapeutic approach at different stages across the lifespan. The breakthrough of highly effective WL drugs makes achieving a WL of >10% possible, which is required for a potential T2D disease remission as well as for prevention of microvascular disease, CKD, CVD events and overall mortality. The aim of this review is to discuss the link between adiposity and CKM conditions as well as placing weight management at the centre of the holistic CKM syndrome approach with a focus on CKD. We propose the clinical translation of the available evidence into a transformative Dysfunctional Adipose Tissue Approach (DATA) for people living with ABCD, T2D and CKD. This model is based on the interplay of four essential elements (i.e. adipocentric approach and target organ protection, dysfunctional adiposity, glucose homeostasis, and lifestyle intervention and de-prescription) together with a multidisciplinary person-centred care. DATA could facilitate decision-making for all clinicians involved in the management of these individuals, and if we do this in a multidisciplinary way, we are prepared to meet the adipocentric challenge.

RESUMEN

Family Accommodation is a very common phenomenon in families where a member has been diagnosed with Obsessive Compulsive Disorder (OCD). The objective of this literature review through the systematic search method was to know the state of the art of the Family Accommodation process in families of adolescents diagnosed with OCD, highlighting the growing literature that addresses the importance of addressing family factors associated with OCD, mainly Family Accommodation, and its implications in prognosis, treatment and quality in family dynamics, making clear the lack of Mexican research that addresses the phenomenon. We found 79 studies that met the inclusion and exclusion criteria, of which 32 identified that accommodation was related to other individual and family variables, 13 analyzed it as a predictor of treatment success or failure, 17 of them focused on evaluating family-focused treatments, 7 analyzed the effects of combined treatments, 3 studies found that accommodation was present in other disorders besides OCD, 2 emphasized the importance of studying the construct in non-Western cultures and 2 more were qualitative. Three studies were identified in unpublished literature and were conducted in Mexican population. This review demonstrated that the literature has shown the importance of including family accommodation in the treatment of pediatric OCD, but there is very little research in Latino and non-Western populations.

RESUMEN

Currently, the modeling of complex chemical-physical processes is drastically influencing industrial development. Therefore, the analysis and study of the combustion process of the boilers using machine learning (ML) techniques are vital to increase the efficiency with which this equipment operates and reduce the pollution load they contribute to the environment. This work aims to predict the emissions of CO, CO2, NOx, and the temperature of the exhaust gases of industrial boilers from real data. Different ML algorithms for regression analysis are discussed. The following are input variables: ambient temperature, working pressure, steam production, and the type of fuel used in around 20 industrial boilers. Each boiler's emission data was collected using a TESTO 350 Combustion Gas Analyzer. The modeling, with a machine learning approach using the Gradient Boosting Regression algorithm, showed better performance in the predictions made on the test data, outperforming all other models studied. It was achieved with predicted values showing a mean absolute error of 0.51 and a coefficient of determination of 99.80%. Different regression models (DNN, MLR, RFR, GBR) were compared to select the most optimal. Compared to models based on Linear Regression, the DNN model has better prediction performance. The proposed model provides a new method to predict CO2, CO, NOx emissions, and exhaust gas outlet temperature.

RESUMEN

Importance: Atrial cardiopathy is associated with stroke in the absence of clinically apparent atrial fibrillation. It is unknown whether anticoagulation, which has proven benefit in atrial fibrillation, prevents stroke in patients with atrial cardiopathy and no atrial fibrillation. Objective: To compare anticoagulation vs antiplatelet therapy for secondary stroke prevention in patients with cryptogenic stroke and evidence of atrial cardiopathy. Design, Setting, and Participants: Multicenter, double-blind, phase 3 randomized clinical trial of 1015 participants with cryptogenic stroke and evidence of atrial cardiopathy, defined as P-wave terminal force greater than 5000 µV × ms in electrocardiogram lead V1, serum N-terminal pro-B-type natriuretic peptide level greater than 250 pg/mL, or left atrial diameter index of 3 cm/m2 or greater on echocardiogram. Participants had no evidence of atrial fibrillation at the time of randomization. Enrollment and follow-up occurred from February 1, 2018, through February 28, 2023, at 185 sites in the National Institutes of Health StrokeNet and the Canadian Stroke Consortium. Interventions: Apixaban, 5 mg or 2.5 mg, twice daily (n = 507) vs aspirin, 81 mg, once daily (n = 508). Main Outcomes and Measures: The primary efficacy outcome in a time-to-event analysis was recurrent stroke. All participants, including those diagnosed with atrial fibrillation after randomization, were analyzed according to the groups to which they were randomized. The primary safety outcomes were symptomatic intracranial hemorrhage and other major hemorrhage. Results: With 1015 of the target 1100 participants enrolled and mean follow-up of 1.8 years, the trial was stopped for futility after a planned interim analysis. The mean (SD) age of participants was 68.0 (11.0) years, 54.3% were female, and 87.5% completed the full duration of follow-up. Recurrent stroke occurred in 40 patients in the apixaban group (annualized rate, 4.4%) and 40 patients in the aspirin group (annualized rate, 4.4%) (hazard ratio, 1.00 [95% CI, 0.64-1.55]). Symptomatic intracranial hemorrhage occurred in 0 patients taking apixaban and 7 patients taking aspirin (annualized rate, 1.1%). Other major hemorrhages occurred in 5 patients taking apixaban (annualized rate, 0.7%) and 5 patients taking aspirin (annualized rate, 0.8%) (hazard ratio, 1.02 [95% CI, 0.29-3.52]). Conclusions and Relevance: In patients with cryptogenic stroke and evidence of atrial cardiopathy without atrial fibrillation, apixaban did not significantly reduce recurrent stroke risk compared with aspirin. Trial Registration: ClinicalTrials.gov Identifier: NCT03192215.

RESUMEN

BACKGROUND: Early in the COVID-19 pandemic, concern about widespread waves of depression and suicide emerged worldwide. Clarity on the relationship between mental health symptoms and warning signs of current self-harm or suicide thoughts and behaviors (ShSTB) in Mexican adults could be useful for designing effective public health policies and preventive strategies during health emergencies. OBJECTIVE: The present study uses a path model to explore the relationship between depressive symptoms, anxiety, and related distress, dysfunction, and somatization with ShSTB warning signs in Mexican adults during the COVID-19 pandemic. The study also describes the relative risks of these mental health variables for men and women, and for those who were seeking psychological care versus those who were not. METHOD: The study was conducted with 18,449 Mexicans (M = 33 years, SD = 11.00, range = 18-59), including 12,188 women (66.10 %) and 2706 (14.67 %) who were seeking psychological care. A web-based application included two multidimensional screening scales to evaluate depression, anxiety and somatic symptoms and related distress/dysfunction, as well as past and current ShSTB. Based on the participants' sex, the entire sample was randomly divided into two sub-samples to compare and replicate the Confirmatory Factor Analysis (CFA) results, getting evidence of the multidimensionality of the scales. With the two sub-samples, we also tested the nested models from a structural equation model (SEM) to suggest a relationship between mental health and self-harm/suicide variables. FINDINGS: Our findings suggest that 31 % of participants were at risk for depression, 42.30 % for anxiety, 38.30 % for Marked Distress, Dysfunction and Somatization (MDDS), 33.30 % for at least one ShSTB, and 4.20 % for Previous Self Harm Thoughts and Behaviors (PShTB) during the COVID-19 pandemic. A greater percentage of women and participants seeking psychological care showed high levels of mental health symptoms, PShTB, MDDS, and ShSTB. The path model suggested a direct influence of PShTB and MDDS on ShSTB. Depression symptoms lead to ShSTB in three possible ways: through PShTB, PShTB affecting MDDS, and generalized anxiety affecting MDDS. DISCUSSION AND OUTLOOK: The pandemic was accompanied by a high prevalence of depression-anxiety, marked distress, dysfunction and somatization and self-harm/suicide thoughts and behaviors. The findings of this study suggest evidence over the well-known association between depression and anxiety, and between depression, previous self-harm thoughts and behaviors, and self-harm/suicide. The evidence suggests to distinguish when participants were suffering from MDDS and anxious depression from those only suffering from depression. The methodological conditions of the study suggest a comprehensive model of ShSTB prevention. Findings also suggest the need to care for Mexicans with depressive symptoms and PShTB as well as those suffering from anxious depression with MDDS to prevent suicide, by implementing effective public health policies and preventive strategies to reduce the mental health gap during health emergencies. LIMITATIONS: This research was a cross-sectional study, suggesting that future analyses should focus on the evaluation of its consistency with confirmed diagnoses of mental health disorders, self-harm/suicide risks, and the effect of remote psychological help to address these problems.

RESUMEN

OBJECTIVE: Develop and obtain content validity of a new tool for Evaluating and Classifying the Severity of Adverse Events for Psychotherapeutic Clinical Trials (EVAD). METHOD: Study of the development process of EVAD in four stages: (1) identify the domain and concept definition through a literature review, (2) instrument design, (3) expert judgment of the EVAD items through Gwent's concordance coefficient, and (4) applicability. RESULTS: In the absence of a consistent conceptual framework of adverse events in psychotherapeutic clinical trials, we have developed a framework and defined it. We have designed EVAD items and their complementary tool for rating adverse events. Content validation by expert judges resulted in CVR = 1.0 for each item and CVI = 0.79 in sufficiency, 0.76 in clarity, 0.91 in coherence and 0.95 in relevance for all items (p < 0.001). Final version of EVAD were applied to three participants for 7 weeks. Overall EVAD seems to be clear and meaningful for participants. CONCLUSIONS: EVAD is a semistructured interview based on a consistent conceptual framework, and proven content validity following the most important guidelines described in the literature. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03878186.

RESUMEN

The development of fleshy fruits involves changes in size and mass, followed by cell differentiation, which is associated with anatomical and histological changes. Parallel to these changes, metabolic alterations lead to the production of osmolytes and energy that modify cell turgor pressure, thereby promoting cell expansion and fruit growth. Detailed information is known about these processes in climacteric fruits (e.g. tomato); however, the regulation of metabolism and its association with anatomical changes in non-climacteric fruit development are poorly understood. In this study, we used detailed anatomical and histological analyses to define three developmental phases of chili pepper (Capsicum chinense cv. Habanero): cell division, cell expansion, and ripening. We showed that each was marked by distinct metabolic profiles, underpinning the switches in energy metabolism to support cellular processes. Interestingly, mitochondrial activity was high in the early stages of development and declined over time, with a modest increase in O2 consumption by pericarp tissues at the beginning of the ripening stage. This respiratory-like burst was associated with the degradation of starch and malate, which are the sources of energy and carbon required for other processes associated with fruit maturation.
