RESUMO

Increasing evidence points out that Executive Functions (i.e., EFs) may be core mechanisms for the generation of resilient responses to adversity. A systematic review testing the relations between either affective (hot) and/or non-affective (cold) EFs (i.e., inhibition, flexibility and working memory updating) and resilience was conducted. A total of 449 articles were initially identified. After two steps of title-and-abstract (k = 449), and full-text reading filtering (k = 67), 11 studies were reviewed. Three studies included cold measures of working memory and supported significant positive relations between higher working memory functioning and higher trait resilience levels. One study included cold measures of inhibition and another one both hot and cold measures, with only the first one supporting a positive relation between more efficient inhibition and higher trait resilience levels. Finally, 7 studies measured flexibility in its cold and/or hot dimensions and overall supported significant relations between higher flexibility and higher levels of trait, process and outcome resilience measures. These results support the role of EFs performance to promote different forms of resilience. This review allows to identify different issues that need to be addressed in future research and highlight the need to integrate the analysis of all hot and cold EFs components to understand their role in the generation of resilience.

RESUMO

Background: Weight loss and lifestyle interventions are the mainstay of treatment in pediatric NAFLD. There are gaps in the literature on the objective improvement in BMI to meaningfully impact NAFLD in children. Aim: To determine the decrease in BMI associated with a significant decline in ALT and other metabolic parameters. Methods: Retrospective chart review of pediatric patients with the diagnosis of NAFLD. Data were collected at the baseline and 6 and 12 months. A linear regression model was used to assess the percent change in BMI predictive of change in ALT and other metabolic parameters. Results: 281 charts were included. 71% of patients who had up to a 2.5% loss in BMI at 6 months had a decrease in ALT of up to 10 U/L compared to 43% patients who did not have a decrease in BMI up to 2.5% loss at the same time period (P=0.01). The linear regression model showed that 6-month and 12-month percent changes in BMI are predictive of 6-month and 12-month ALT changes (P=0.01 and 0.02), respectively. ALT normalization was achieved on 12% of patients with a ≥2.5% decrease in BMI at 6 months compared to 1% of patients that had no decrease of ≥2.5% decrease in BMI at 6 months (P=0.01). The mean BMI Z-score decline was 0.18 (P=0.001) in the group with a ≥2.5% decrease in BMI at 6 months. Conclusions: BMI loss of up to 2.5% and the mean BMI Z-score 0.18 are associated with a significant decrease in ALT of up to 10 U/L. BMI percent change at 6 months and 12 months is predictive of changes in ALT. These results should help guide providers in clinical practice set objective goals for the management of children with NAFLD resulting from obesity.

RESUMO

BACKGROUND: Negative childbirth experiences can be related to the onset of perinatal post-traumatic stress symptomatology (P-PTSS), which significantly impacts the mother and the infant. As a response in the face of the discomfort caused by P-PTSS, maladaptive emotion regulation strategies such as brooding can emerge, contributing to the consolidation of post-partum depressive symptoms. Ultimately, both types of symptomatology, P-PTSS and post-partum depression, can act as risk factors for developing mother-child bonding difficulties. Still, this full set of temporal paths has to date remained untested. The present longitudinal study aimed to analyze the risk factors associated with the appearance of P-PTSS after post-partum and to test a path model considering the role of P-PTSS as an indirect predictor of bonding difficulties at eight months of postpartum. METHODS: An initial sample of pregnant women in the third trimester of gestation (N = 594) participated in a longitudinal study comprising two follow-ups at two and eight months of postpartum. The mothers completed online evaluations that included socio-demographic data and measures of psychological variables. A two-step linear regression model was performed to assess the predictive role of the variables proposed as risk factors for P-PTSS, and a path model was formulated to test the pathways of influence of P-PTSS on bonding difficulties. RESULTS: A history of psychopathology of the mother, the presence of depression during pregnancy, the presence of medical complications in the mother, and the occurrence of traumatic birth experiences all acted as significant predictors of P-PTSS, explaining 29.5% of its variance. Furthermore, the path model tested further confirmed an indirect effect of P-PTSS, triggered by a negative childbirth experience, on subsequent bonding difficulties eight months after labor through its association with higher levels of brooding and, ultimately, postpartum depression levels. A further path showed that bonding difficulties at two months postpartum can persist at eight months postpartum due to the onset of brooding and postpartum depression symptoms. CONCLUSION: We identified a set of robust predictors of P-PTSS: the mother's previous history of depression, perinatal depression during pregnancy, the presence of medical complications in the mother and the occurrence of traumatic birth experiences, which has important implications for prevention. This is particularly relevant, as P-PTSS, when triggered by a negative childbirth experience, further indirectly predicted the development of mother-child bonding difficulties through the mediation of higher use of brooding and symptoms of postpartum depression. These findings can serve as a basis for developing new longitudinal studies to further advance the understanding of perinatal mechanisms of mental health.

RESUMO

We have studied the rich dynamics of a damped particle inside an external double-well potential under the influence of state-dependent time-delayed feedback. In certain regions of the parameter space, we observe multistability with the existence of two different attractors (limit cycle or strange attractor) with well separated mean Lyapunov energies forming a two-level system. Bifurcation analysis reveals that, as the effects of the time-delay feedback are enhanced, chaotic transitions emerge between the two wells of the double-well potential for the attractor corresponding to the fundamental energy level. By computing the residence time distributions and the scaling laws near the onset of chaotic transitions, we rationalize this apparent tunneling-like effect in terms of the crisis-induced intermittency phenomenon. Further, we investigate the first passage times in this regime and observe the appearance of a Cantor-like fractal set in the initial history space, a characteristic feature of hyperbolic chaotic scattering. The non-integer value of the uncertainty dimension indicates that the residence time inside each well is unpredictable. Finally, we demonstrate the robustness of this tunneling intermittency as a function of the memory parameter by calculating the largest Lyapunov exponent.

RESUMO

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.

RESUMO

INTRODUCTION: Liver disease is a leading cause of morbidity and mortality among persons living with HIV (PLHIV). While chronic viral hepatitis has been extensively studied in low- and middle-income countries (LMICs), there is limited information about the burden of metabolic disorders on liver disease in PLHIV. METHODS: We conducted a cross-sectional analysis of baseline data collected between October 2020 and July 2022 from the IeDEA-Sentinel Research Network, a prospective cohort enrolling PLHIV ≥40 years on antiretroviral treatment (ART) for ≥6 months from eight clinics in Asia, Americas, and central, East, southern and West Africa. Clinical assessments, laboratory testing on fasting blood samples and liver stiffness measurement (LSM)/controlled attenuation parameter (CAP) by vibration-controlled transient elastography were performed. Multivariable logistic regression models assessed factors associated with liver fibrosis (LSM ≥7.1 kPa) and steatosis (CAP ≥248 dB/m). Population attributable fraction (PAF) of each variable associated with significant liver fibrosis was estimated using Levin's formula. RESULTS: Overall, 2120 PLHIV (56% female, median age 50 [interquartile range: 45-56] years) were included. The prevalence of obesity was 19%, 12% had type 2 diabetes mellitus (T2DM), 29% had hypertension and 53% had dyslipidaemia. The overall prevalence of liver fibrosis and steatosis was 7.6% (95% confidence interval [CI] 6.1-8.4) and 28.4% (95% CI 26.5-30.7), respectively, with regional variability. Male sex at birth (odds ratio [OR] 1.62, CI 1.10-2.40), overweight/obesity (OR = 2.50, 95% CI 1.69-3.75), T2DM (OR 2.26, 95% CI 1.46-3.47) and prolonged exposure to didanosine (OR 3.13, 95% CI 1.46-6.49) were associated with liver fibrosis. Overweight/obesity and T2DM accounted for 42% and 11% of the PAF for liver fibrosis, while HBsAg and anti-HCV accounted for 3% and 1%, respectively. Factors associated with steatosis included overweight/obesity (OR 4.25, 95% CI 3.29-5.51), T2DM (OR 2.06, 95% CI 1.47-2.88), prolonged exposure to stavudine (OR 1.69, 95% CI 1.27-2.26) and dyslipidaemia (OR 1.68, 95% CI 1.31-2.16). CONCLUSIONS: Metabolic disorders were significant risk factors for liver disease among PLHIV in LMICs. Early recognition of metabolic disorders risk factors might be helpful to guide clinical and lifestyle interventions. Further prospective studies are needed to determine the causative natures of these findings.

RESUMO

Background: There is growing evidence of fungal infections associated with COVID-19. The development of cryptococcosis in these patients has been infrequently reported. However, it can be life-threatening. Objective: To identify cases of COVID-19 patients who developed cryptococcosis and to compare baseline characteristics and management between those who survived and those who died. Methods: We conducted a scoping review using PubMed, Scopus, Web of Science, and Embase to identify studies that reported patients with COVID-19 and cryptococcosis. No language restriction was applied. Single case reports, case series, and original articles were included. It is important to note that 'n' refers to the total number of individuals with the specified variable. Results: A total of 58 studies were included. Among these studies, 51 included individual patient data, detailing information on a total of 65 patients, whereas eight studies reported the proportion of cryptococcosis in COVID-19 patients. One study provided both individual and aggregate case information. From individual patient data, the majority were male (73.9%; n = 48) with a median age of 60 years (range: 53-70). Severe COVID-19 and multiple comorbidities, led by arterial hypertension and diabetes mellitus, were frequently reported, but few had classic immunosuppression factors. On the other hand, HIV status, either negative or positive, was reported in just over half of the patients (61.5%; n = 40). Most were admitted to the intensive care unit (ICU) (58.5%; n = 31), received mechanical ventilation (MV) (50.0%; n = 26), and developed disseminated cryptococcosis (55.4%; n = 36). Secondary infection, mainly bacterial, was reported in 19 patients (29.2%). Mortality was 47.7% (n = 31). Of the studies that reported the proportion of cryptococcosis in COVID-19 cases, the majority were descriptive studies published as conference abstracts. Conclusion: Cryptococcosis in COVID-19 patients has been reported more frequently. However, it is still not as common as other fungal infections associated with COVID-19. Few patients have some classic immunosuppression factors. The factors associated with mortality were male sex, age, ICU admission, MV, secondary infections, and lymphopenia.

RESUMO

High-density probes allow electrophysiological recordings from many neurons simultaneously across entire brain circuits but don't reveal cell type. Here, we develop a strategy to identify cell types from extracellular recordings in awake animals, revealing the computational roles of neurons with distinct functional, molecular, and anatomical properties. We combine optogenetic activation and pharmacology using the cerebellum as a testbed to generate a curated ground-truth library of electrophysiological properties for Purkinje cells, molecular layer interneurons, Golgi cells, and mossy fibers. We train a semi-supervised deep-learning classifier that predicts cell types with greater than 95% accuracy based on waveform, discharge statistics, and layer of the recorded neuron. The classifier's predictions agree with expert classification on recordings using different probes, in different laboratories, from functionally distinct cerebellar regions, and across animal species. Our classifier extends the power of modern dynamical systems analyses by revealing the unique contributions of simultaneously-recorded cell types during behavior.

RESUMO

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.

RESUMO

OBJECTIVES: Cystatin C is increasingly used as a marker of renal function as a complement to serum creatinine and glomerular filtration rate (GFR). We have assessed its efficacy as a predictor of mortality in a group of patients with increased cystatin C but GFR> 60mL/min. DESIGN AND METHODS: We included 608 patients, 65.9% male, 34.6% had diabetes mellitus. The mean age was 58.5±14.5 years and a mean GFR of 64.1±33.5mL/min. Patients were divided into 3 groups: CONTROL (normal cystatin C and GFR> 60mL/min, age 53.3±12.8years, GFR 96.6±22.4mL/min,n=193), INCREASED CYSTATIN (cystatin C>1.03mg/l and GFR>60mL/min, age 58.9±13,1years, GFR 72.2±10.4mL/min, n=40) and CKD (chronic kidney disease, increased cystatin C and GFR <60mL/min, age 61.4±14.8years, GFR 36.0±12.7mL/min, n=160). The relationship with overall mortality was analyzed using the Kaplan-Meier method. RESULTS: Mean cystatin C was 0.75±0.13 versus 1.79±0.54 in CKD group and 1.14±0.14mg/l, p <0.001). In CONTROL group survival was 93.9% at 5y, compared to 78.8% in the ERC group and 82.3% in the INCREASED CYSTATIN group (p <0.001) Five-year survival before renal replacement therapy was also different for the ERC group (73%, p <0.001 Log Rank) but not between the other two groups (CONTROL 99.0%, INCREASED CYSTATIN 94.3% p=0.08). CONCLUSIONS: Increased plasmatic levels of cystatin C in patients with GFR> 60mL/min was a predictor of increased mortality but not of progression to end-stage renal failure. These results confirm the interest of routinely measuring cystatin C.

RESUMO

BACKGROUND: The impact of co-management on clinical outcomes in neurosurgical patients is uncertain. This study aims to describe the implementation of a hospitalist co-management program in a neurosurgery department and its impact on the incidence of complications, mortality, and length of stay. METHODS: The authors used a quasi-experimental study design that compared a historical control period (July-December 2017) to a prospective intervention arm. During the intervention period, patients admitted to a neurosurgery inpatient unit who were older than 65 years, suffered certain conditions, or were admitted from ICUs were included in the co-management program. Two hospitalists joined the surgical staff and intervened in the diagnostic and therapeutical plan of patients, participating in clinical decisions and coordinating patient navigation with neurosurgeons. The incidence of moderate or severe complications measured by the Accordion Severity Grading System, in-hospital mortality, and length of stay of the two cohorts were compared. Multivariate regression was used to adjust for confounders, and the average treatment effect was estimated using inverse probability of treatment weighting. RESULTS: The adjusted incidence of moderate or severe complications was lower among co-managed patients (odds ratio [OR] 0.60, 95% confidence interval [CI] 0.39-0.91). Mortality was unchanged (OR 0.83, 95% CI 0.15-4.17). Length of stay was lower in co-managed patients, with a 1.3-day reduction observed after inverse probability of treatment weighting analysis. CONCLUSION: Hospitalist co-management was associated with a reduced incidence of complications and length of stay in neurosurgical patients, but there was no difference in in-hospital mortality.

RESUMO

Background: Brief therapies have proven to reduce tobacco cost-effectively, however, unsuccessful quit attempts remain notable in real-life conditions, and the underlying mechanisms of treatment success are still unclear. Objectives: We aimed to analyze the effectiveness of the Guided Self-Change (GSC) therapy combined with varenicline (VAR+T) in public health services against varenicline alone (VAR), and to identify mediators of treatment outcomes. We conducted a two-arm quasi-experimental study with 126 treatment-seeking smokers (age=57.3±9.1 years; 59.5% women). Before treatment, and at weeks 12 and 24, we assessed tobacco use and five potential mediators: withdrawal, craving, motivation to quit, anxiety, and depression. Results: Only 25% of participants adhered to varenicline prescription, and 54% to GSC therapy. VAR+T group showed a greater proportion of abstainers compared to VAR group at week 12 (75% vs 57.4%; φc=0.21) and week 24 (62.9% vs 52.5%; φc=0.10). When controlling for weeks taking varenicline, motivation showed a significant indirect effect over abstinence rates in VAR+T compared with VAR (a1b1=1.34; 95%CI=0.04, 5.03). Conclusions: The GSC effectiveness seems to increase motivation which in turn contributes to reducing tobacco use. The implementation of GSC therapy in public health services could minimize treatment duration and increase smoking abstinence in 'real-life' conditions where varenicline adherence remains low.

RESUMO

Objectives: To describe the complications associated with the different gastrostomy techniques [endoscopic (PEG), radiologic (PRG), and surgical (SG)] performed in the last 26 years in a terciary hospital. Methods: Retrospective observational study. Patients who underwent gastrostomy at the Virgen del Rocío University Hospital between 1995 and 2021 were included. For PEG, the PULL technique was performed until 2018 and subsequently the PUSH technique predominantly. For PRG, a pigtail catheter was used until 2003, a balloon catheter between 2003 and 2009, and a balloon catheter with gastropexy between 2015 and 2021. For SG, the conventional technique (CSG) was performed until 2009 and since then the laparoscopic assisted percutaneous gastrostomy (PLAG) technique. Descriptive analysis was performed obtaining the median and quartiles of the quantitative variables [P50 (P25-P75)] and the frequency for the qualitative variables [n (%)].The comparison of complications between patients who underwent different techniques was performed with Fisher's test. Results: n = 1,070 (PEG = 608, PRG = 344, SG = 118). The three most frequent indications were head and neck tumors, neurological diseases and gastroesophageal tumors. The percentage of patients who had any complication was 48.9% (PEG-PULL), 23.7% (PEG-PUSH), 38.5% (pigtail PRG), 39.2% (balloon PRG), 29.7% (balloon with gastropexy PRG), 87.3% (CSG), and 41.26% (PLAG). 2 (0.18%) patients died from gastrostomy-related complications. 18(1.68%) presented with peritonitis and 5 (0.4%) presented with gastrocolic fistula. The rest of the complications were minor. Conclusion: Gastrostomy in any of its modalities is currently a safe procedure with a low rate of complications, most of which are minor.

RESUMO

Over the last decades, we have witnessed a constant increase in infections caused by multi-drug-resistant strains in emergency departments. Despite the demonstrated effectiveness of antimicrobial stewardship programs in antibiotic consumption and minimizing multi-drug-resistant bacterium development, the characteristics of emergency departments pose a challenge to their implementation. The inclusion of rapid diagnostic tests, tracking microbiological results upon discharge, conducting audits with feedback, and implementing multimodal educational interventions have proven to be effective tools for optimizing antibiotic use in these units. Nevertheless, future multicenter studies are essential to determine the best way to proceed and measure outcomes in this scenario.

RESUMO

OBJECTIVE: The aim of this research was to study the ways in which problems of adaptation to pregnancy influence the development of symptoms of perinatal depression via the presence of brooding and low maternal-fetal bonding, in addition to other risk factors previously established in the literature. STUDY DESIGN: Representative sample of pregnant women in the third trimester of gestation (N = 594) completed an online survey that included sociodemographic data and measures of perinatal depression, adjustment to pregnancy, bonding, and brooding. Other risk factors were also assessed as covariates, such as previous history of depression, generalized anxiety, perceived social support, and experience of stressful life events. Descriptive and correlational analyses were performed on the scores obtained by the subjects with the different instruments. A path model was formulated to establish the pathways through which adjustment influences perinatal depression symptomatology. On the one hand, the presence of brooding (worst adjustment to pregnancy → high brooding → perinatal depression symptomatology), and on the other hand, the quality of maternal-fetal bonding (worst adjustment to pregnancy → poor quality fetal-maternal bonding → perinatal depression symptomatology) would act as a mediator. RESULTS: The factors proposed by the literature were predictive of perinatal depressive symptomatology and the quality of adjustment to pregnancy. Problems adjusting to changes during pregnancy and experiencing it unsatisfactorily may predict individual differences in perinatal depressive symptoms. Significantly, this relationship was mediated by two key factors, the presence of brooding and low quality of the maternal-fetal bond. CONCLUSION: Our results provide evidence in favor of the existence of multiple paths through which difficulties in adapting to pregnancy can favor the occurrence of higher levels of perinatal depressive symptoms and identify new avenues for developing research in this area and preventive interventions empirically informed.

RESUMO

INTRODUCTION: Early adolescence represents a time of heightened vulnerability for depression. Negative interpretation biases have been associated with increases in depressive symptoms during this developmental period; however, the mechanisms underlying the association between interpretation biases and depression remain poorly understood. Cognitive theories posit that interpretation biases give rise to depression by modulating daily affect, particularly in the context of stress. However, this has not yet been directly examined. The present study tested affect intensity and instability as mechanisms linking negative interpretation biases with change in adolescent depressive symptoms. METHODS: Ninety-four adolescents (aged 11-13 years; 51% boys) from Vancouver, Canada, were recruited for this longitudinal study. At baseline (Time 1), participants self-reported depressive symptoms and completed the Scrambled Sentences Task to assess negative interpretation biases. Next, participants completed daily diaries to assess positive affect (PA) and negative affect (NA) during a naturalistic stressor-the first 2 weeks of high school (Time 2). Finally, participants self-reported depressive symptoms 3 months later (Time 3). Path models were conducted to test whether PA and NA intensity and instability mediated prospective associations between negative interpretation biases and depressive symptom changes. RESULTS: Although NA intensity, NA instability, and PA instability predicted increases in depressive symptoms, only NA intensity mediated associations between interpretation biases and symptom changes. Neither PA intensity nor instability mediated these associations. CONCLUSIONS: Elevated daily NA represents a specific mechanism through which stronger negative interpretation biases predict increases in depressive symptoms in adolescence.

RESUMO

Introduction: One of the most damaging aspects, both for people's well-being and for close relationships, is conflict. Beyond different stressors, the emotions evoked, their regulation and an appropriate conflict resolution strategy will reduce negative consequences. Emotional Intelligence facilitates social relationships, but little applied research has been done on the relationship with couple conflict and emotional flooding, particularly from the perspective of women. Therefore, the present study analyzes the role of Perceived Emotional Intelligence (PEI) and the mediating effect of Positive Conflict Resolution strategies (PCR) in couples' conflicts from women's perspective, examining its effect on Emotional Flooding (EF) and Satisfaction. Methods: Through a cross-sectional design, the relationships between variables were analyzed using group comparisons and means of a structural equation model (SEM) in a sample of 692 women. Results: Significant differences were found between the groups by age, length of relationship, and motherhood. The SEM revealed a good fit. PEI predicted 71.8% of the variance in EF and 35% in Satisfaction through PCR and Conflict.

RESUMO

Invasive aspergillosis (IA) is a major cause of morbidity and mortality in patients receiving allogeneic haematopoieticcell transplantation. The deep immunosuppression and a variety of potential additional complications developed in these patients result in IA reaching mortality rates of around 50-60%. This mortality is even higher when the patients are infected with azole-resistant isolates, demonstrating that, despite the complexity of management, adequate azole treatment can have a beneficial effect. It is therefore paramount to understand the reasons why antifungal treatment of IA infections caused by azole-susceptible isolates is often unsuccessful. In this respect, there are already various factors known to be important for treatment efficacy, for instance the drug concentrations achieved in the blood, which are thus often monitored. We hypothesize that antifungal persistence may be another important factor to consider. In this study we present two case reports of haematological patients who developed proven IA and suffered treatment failure, despite having been infected with susceptible isolates, receiving correct antifungal treatment and reaching therapeutic levels of the azole. Microbiological analysis of the recovered infective isolates showed that the patients were infected with multiple strains, several of which were persisters to voriconazole and/or isavuconazole. Therefore, we propose that azole persistence may have contributed to therapeutic failure in these patients and that this phenomenon should be considered in future studies.
