OBJECTIVES/GOALS: The Title V Coop developed CRESCO, a physical and virtual space in the libraries of the two cooperating institutions. Adopting a flexible and transformational approach, it offers services to support the development of research and information skills of undergraduate students and faculty who receive clinical-translational research (CTR) training. METHODS/STUDY POPULATION: Since 2016, CRESCO has been staffed by a multidisciplinary team composed of three librarians, a statistician, an instructional designer, and an IT specialist. The physical facilities of the two libraries were remodeled and equipped, and a central portal was created to provide services and access to resources on a 7/24 basis. Online tutorials, workshops, and mentoring services have been offered that address topics in statistics, literature search, plagiarism, and the use of several research software. Services statistics are collected, and a questionnaire is administered to evaluate the workshops. RESULTS/ANTICIPATED RESULTS: The main results include 12 online tutorials created in CTR areas and available in the CRESCO hub portal; 14,660 mentoring/consultations offered in statistics, the use of research-related software, and the search for scientific literature search; and 6 online workshops created in CTR areas, with 463 attendees. When evaluating online workshops, participants considered that their acquired learning was high or extremely high on the following topics: use of Intellectus Statistics (88%, n = 96); selection of statistical tests (81%, n = 92); use of Turnitin (85%, n = 76); literature search (91%, n = 58); and citations and references in Mendeley (90%, n = 67). DISCUSSION/SIGNIFICANCE: These results suggest that the flexible, multidisciplinary, and transformational approach of CRESCO has been successful in helping undergraduate students and faculty develop the skills necessary to conduct CTR projects.
The British Society for Parasitology (BSP) holds a biannual symposium devoted to the kinetoplastids, and seeks to cover the full gamut of research into these important organisms, and alternates with the Woods Hole Kinetoplastid Molecular Cell Biology meeting that serves a similar community. While normally embedded within the main BSP Spring meeting, on several occasions the symposium has enjoyed the opportunity of being hosted on mainland Europe. In 2020, the BSP was fortunate to spend some time in Granada in Spain, where a superb meeting with excellent science in a spectacular setting was overshadowed by news of an emerging novel coronavirus. In this editorial, we hope to have captured some of that excellent science and to highlight aspects of the many great papers and reviews in this special issue, as well as provide a few images from the meeting, which we hope for this who attended will bring back some fond memories.
To examine associations between household food insecurity and children’s physical activity and sedentary behaviours.
Secondary analysis was conducted on the Healthy Communities Study, an observational study from 2013 to 2015. Household food insecurity was assessed by two items from the US Department of Agriculture’s 18-item US Household Food Security Survey Module. Physical activity was measured using the 7-d Physical Activity Behaviour Recall instrument. Data were analysed using multilevel statistical modelling.
A total of 130 communities in the USA.
In sum, 5138 US children aged 4–15 years.
No associations were found for the relationship between household food insecurity and child physical activity. A significant interaction between household food insecurity and child sex for sedentary behaviours was observed (P = 0·03).
Additional research capturing a more detailed assessment of children’s experiences of food insecurity in relation to physical activity is warranted. Future studies may consider adopting qualitative study designs or utilising food insecurity measures that specifically target child-level food insecurity. Subsequent research may also seek to further explore sub-group analyses by sex.
In strong electromagnetic regimes, gyrokinetic simulations have linked a substantial ion-scale turbulence stabilization to the presence of supra-thermal particles, capturing qualitatively well the experimental observations in different devices worldwide. An explanation for the underlying physical mechanism responsible for the fast-ion-induced turbulent transport reduction observed in the numerical simulations has been proposed only recently by Di Siena et al. (Nucl. Fusion, vol. 59, 2019, p. 124001; Nucl. Fusion, vol. 60, 2020, p. 089501). It involves a nonlinear cross-scale coupling (nonlinear interaction involving different modes at different wavenumbers) between ion-temperature-gradient and marginally stable Alfvén eigenmodes, which in turn increases zonal flow activity. In view of an optimization of this turbulence-stabilizing effect, the key parameters controlling the nonlinear cross-scale coupling are here identified. At the same time, these findings provide useful insights for reduced-turbulence models and integrative approaches, which might be trained on the results presented in this paper to grasp the underlying physics and the parameter scaling of the beneficial effects of fast particles on plasma turbulence.
Conflicting results have been obtained through meta-analyses for the role of obesity as a risk factor for adverse outcomes in patients with coronavirus disease-2019 (COVID-19), possibly due to the inclusion of predominantly multimorbid patients with severe COVID-19. Here, we aimed to study obesity alone or in combination with other comorbidities as a risk factor for short-term all-cause mortality and other adverse outcomes in Mexican patients evaluated for suspected COVID-19 in ambulatory units and hospitals in Mexico. We performed a retrospective observational analysis in a national cohort of 71 103 patients from all 32 states of Mexico from the National COVID-19 Epidemiological Surveillance Study. Two statistical models were applied through Cox regression to create survival models and logistic regression models to determine risk of death, hospitalisation, invasive mechanical ventilation, pneumonia and admission to an intensive care unit, conferred by obesity and other comorbidities (diabetes mellitus (DM), chronic obstructive pulmonary disease, asthma, immunosuppression, hypertension, cardiovascular disease and chronic kidney disease). Models were adjusted for other risk factors. From 24 February to 26 April 2020, 71 103 patients were evaluated for suspected COVID-19; 15 529 (21.8%) had a positive test for SARS-CoV-2; 46 960 (66.1%), negative and 8614 (12.1%), pending results. Obesity alone increased adjusted mortality risk in positive patients (hazard ratio (HR) = 2.7, 95% confidence interval (CI) 2.04–2.98), but not in negative and pending-result patients. Obesity combined with other comorbidities further increased risk of death (DM: HR = 2.79, 95% CI 2.04–3.80; immunosuppression: HR = 5.06, 95% CI 2.26–11.41; hypertension: HR = 2.30, 95% CI 1.77–3.01) and other adverse outcomes. In conclusion, obesity is a strong risk factor for short-term mortality and critical illness in Mexican patients with COVID-19; risk increases when obesity is present with other comorbidities.
The aim of this study is to test the psychometric properties of the Spanish validation of the Fear of COVID-19 Scale (FCV-19S) in a Paraguayan population.
Participants were recruited through an Internet-based survey. All participants whose scores in the Hospital Anxiety and Depression Scale (HADS) and The Fear Questionnaire (FQ) were greater than zero were included. 1245 subjects responded voluntarily: 1077 subjects, scoring >0, were considered.
To establish construct validity of the FCV-19S, an exploratory factor analysis was performed using the KMO test, which was adequate, and the Bartlett sphericity test, which was significant (p <.0001). The CFI, NFI, GFI, TLI and RMSEA indices were used to evaluate the model and showed good adjustment. Cronbach’s α showed valid internal consistency (α = 0.86). This validation was supported by significant correlation (p <.001) with the HADS scale for anxiety and depression and with the FQ scale for specific phobia.
The Spanish version of the FCV-19S is a 7-item scale with two dimensions, psychological symptoms and physiological symptoms, which demonstrated robust psychometric properties in a Paraguayan population.
Most of the existing prediction models for COVID-19 lack validation, are inadequately reported or are at high risk of bias, a reason which has led to discourage their use. Few existing models have the potential to be extensively used by healthcare providers in low-resource settings since many require laboratory and imaging predictors. Therefore, we sought to develop and validate a multivariable prediction model of death in Mexican patients with COVID-19, by using demographic and patient history predictors. We conducted a national retrospective cohort study in two different sets of patients from the Mexican COVID-19 Epidemiologic Surveillance Study. Patients with a positive reverse transcription-polymerase chain reaction for SARS-CoV-2 and complete unduplicated data were eligible. In total, 83 779 patients were included to develop the scoring system through a multivariable Cox regression model; 100 000, to validate the model. Eight predictors (age, sex, diabetes, chronic obstructive pulmonary disease, immunosuppression, hypertension, obesity and chronic kidney disease) were included in the scoring system called PH-Covid19 (range of values: −2 to 25 points). The predictive model has a discrimination of death of 0.8 (95% confidence interval (CI) 0.796–0.804). The PH-Covid19 scoring system was developed and validated in Mexican patients to aid clinicians to stratify patients with COVID-19 at risk of fatal outcomes, allowing for better and efficient use of resources.
Technological and mathematical advances have provided opportunities to investigate new approaches for the holistic quantification of complex biological systems. One objective of these approaches, including the multi-inverse deterministic approach proposed in this paper, is to deepen the understanding of biological systems through the structural development of a useful, best-fitted inverse mechanistic model. The objective of the present work was to evaluate the capacity of a deterministic approach, that is, the multi-inverse approach (MIA), to yield meaningful quantitative nutritional information. To this end, a case study addressing the effect of diet composition on sheep weight was performed using data from a previous experiment on saccharina (a sugarcane byproduct), and an inverse deterministic model (named Paracoa) was developed. The MIA successfully revealed an increase in the final weight of sheep with an increase in the percentage of corn in the diet. Although the soluble fraction also increased with increasing corn percentage, the effective nonsoluble degradation increased fourfold, indicating that the increased weight gain resulted from the nonsoluble substrate. A profile likelihood analysis showed that the potential best-fitted model had identifiable parameters, and that the parameter relationships were affected by the type of data, number of parameters and model structure. It is necessary to apply the MIA to larger and/or more complex datasets to obtain a clearer understanding of its potential.
There is a substantial proportion of patients who drop out of treatment before they receive minimally adequate care. They tend to have worse health outcomes than those who complete treatment. Our main goal is to describe the frequency and determinants of dropout from treatment for mental disorders in low-, middle-, and high-income countries.
Respondents from 13 low- or middle-income countries (N = 60 224) and 15 in high-income countries (N = 77 303) were screened for mental and substance use disorders. Cross-tabulations were used to examine the distribution of treatment and dropout rates for those who screened positive. The timing of dropout was examined using Kaplan–Meier curves. Predictors of dropout were examined with survival analysis using a logistic link function.
Dropout rates are high, both in high-income (30%) and low/middle-income (45%) countries. Dropout mostly occurs during the first two visits. It is higher in general medical rather than in specialist settings (nearly 60% v. 20% in lower income settings). It is also higher for mild and moderate than for severe presentations. The lack of financial protection for mental health services is associated with overall increased dropout from care.
Extending financial protection and coverage for mental disorders may reduce dropout. Efficiency can be improved by managing the milder clinical presentations at the entry point to the mental health system, providing adequate training, support and specialist supervision for non-specialists, and streamlining referral to psychiatrists for more severe cases.
To study whether there are personality characteristics that discriminate between IPV women and non-abused control women, taking into account the effect of emotional state (depressive symptoms).
A total of 176 women victim of IPV and 193 non-abused control women were assessed with the Dimensional Assessment of Personality Pathology (DAPP-BQ; Livesley, 1990), the Beck Depression Inventory -II (BDI-II; Beck, 1996), and the Index of Spouse Abuse (ISA; Hudson & McIntosh, 1981). Women victim of IPV were recruited from Domestic Violence Centers, and non-abused control women were recruited from Primary Care Centers and Mental Health Services. A two way analysis of variance (IPV * Depression) were used for detecting differences in personality traits taking into account the effect of depression (BDI ≥ 17).
After controlling for depression, IPV victims scored higher than control women in submissiveness (F=6.41; p=0.01), cognitive distortion (F=4.35; p=0.04), intimacy problems (F=27.02; p< 0.001), suspiciousness (F=5.02; p=0.03) and self-harm (F=4.93; p=0.03), and lower in rejection (F=14.66; p< 0.001).
IPV victims showed high submission, low hostility, intimacy problems, suspiciousness, tendency to depersonalization or derealization, and suicidal ideation and attempts, as a result of chronic abuse. Some of these aspects could be explained by the presence of PTSD, more than by pre-existing personality characteristics. Traumatic and chronic stress can alter functional aspects of the brain and lead to the development of dysfunctional cognitive and behavioral characteristics that may be considered in the psychotherapeutic approach.
The goal of this research was to explore the use of PCR as a marker of inflammation and CVD in patients with Schizophrenia.
A cross-sectional analysis of the BSA administrative claim database was conducted including all men and women, >18 years, with a schizophrenia spectrum disorders (by DSM-IV criteria) diagnosis. PCR measurement together with socio-demographics, evolution, medical history, 10-years CVD risk (Framingham equation) and biochemistry data was extracted for analysis.
705 patients [53.0% men, 48.2 ± 15.8 years (mean ± SD), 5.9 ± 3.2 years of evolution, 79.7% on atypical drugs] met criteria for analysis. Mean 10-year CVD risk was high; 11.9% ± 5.7% and mean PCR levels were 2.6 + 2.5 mg/L with 30.4% showing values above normal's (≥ 3 mg/L). Unadjusted PCR slightly correlated with CVD risk; r = 0.171, p < 0.001. After adjusting by age, sex, evolution, smoking and anti-inflammatory drugs treatment, PCR was linearly associated with 10-year CVD risk stratified by its level of risk (low, moderate, high/very high); respectively, 2.3 (95% CI: 2.1–2.5), 3.1 (2.6–3.5) and 3.7 (3.2–4.1) mg/L; F = 13.5, p < 0.001. Patients with known CVD showed also higher PCR levels; 3.7 (2.9–4.5) vs. 2.5 (2.4–2.7) mg/L, p = 0.008, and higher probability of values above normal's; Odds Ratio = 4.71 (2.01–11.04), p < 0.001.
High PCR levels (above normals) were associated with both known CVD and high/very high 10-year risk of CVD event in patients with schizophrenia. Then, PCR might be a marker of inflammation and CVD in this psychiatric disorder.
The aim of this study was to identify risk factors in early postpartum that predict postpartum depression (PPD) at 6-8 weeks.
A prospective cohort of 309 women was studied between the 2nd-3rd days postpartum and at 6-8 weeks postpartum. Initially we administered a general information questionnaire that included obstetrical variables and history of personal and family affective disorders. Between the 2nd and 3rd days postpartum they filled out the Spanish version of the Edinburgh Postnatal Depression Scale (EPDS), Spielberg Anxiety Trait and State Inventory (STAI-R/S), Neuroticism Dimension (EPQ), St Paul Ramsey Questionnaire (life events) and Duke Social Support Scale. At 6-8 weeks postpartum they filled out again the EPDS. Women who scored ≥10 were screened as having PPD.
The incidence of PPD at 6-8 weeks was 14.6%. After Bonferroni correction, univariated analysis showed that previous personal history of depression (p<0.001), high neuroticism (p<0.001), low social support (p<0.002) and high EPDS (p<0.001) in the immediate postpartum were associated with PPD. Logistical regression analysis identified previous personal history of depression and high initial level of depression (OR=14.6; 95%CI=4.8-12.2; p<0.001) as risk factors for PPD. The absence of signification of the Hosmer-Lemersshow test (x2 =9.654; df=8; p=0.290) indicated the goodness-of-fit of the prediction model.
A previous history of depression and EPDS≥10 in the immediate postpartum allow to identify women with high risk of PPD before leaving the Obstetric Ward.
This study has been supported in part by grants: Instituto Carlos III: GO3/184; FIS: PI041783 and FIS 05/2565.
To examine whether the postpartum depression (PPD) subgroup with positive antithyroid antibodies (Ab+) compared with the PPD subgroup without positive presence of Ab (Ab -) have a different psycho-social and psychopathological characteristics.
One hundred three (N=103) patients with PPD according with DSM-IV criteria were included. Autoimmune status of the thyroid (Thyroperoxidasa antibodies, Thyroglobulin antibodies), severity of depression and anxiety (EPDS and 21-item Hamilton and STAI-S scales), psychosocial variables (Early Trauma Inventory, Saint Paul Ramsey Questionnaire, Marital Adjustment Test) were assessed joint with other several demographics and reproductive variables.
The presence of childhood sexual abuse in PPD women increase the probability of Ab(+) (OR= 2,528 ; 95% CI =1,00-6,39). The levels of Thyroid peroxidase antibodies (TPOAb) titers have a strongly correlation (p<0,000) with the levels of the Early Trauma Inventory.
The results of our study give a link between early stress, the immune system, and postpartum depression.The implication of the immunitary system in the etiopathogenesis of the PPD through the long lasting sensitization of the inflammatory response system and the endocrine system in front to stress behind the CNS and their transmisors and receptors activation is discussed.
To design a scale to measure perceived reasons to stay in violent partner relationships, and to carry out a preliminar analysis of its psychometric properties.
A 44 dicotomic items (true/false) self-report scale was designed (more a last open response question), elaborated according to published studies and open interviews with battered women. The questionnaire was administered to a pilot sample of 10 women to test its viability and comprehensibility. The questionnaire was then administered to a sample of 132 battered women. Exploratory factorial analysis was used to establish the underlying empirical structure. Internal consistency was calculated by mean of Cronbach's alfa coefficient.
The factor analysis identified two empirical factors: external factor (situational factor) and internal factor (psychological factors). Cronbach's alphas were 0.856 and 0.811, respectively.
The Block Escape in Intimate Partner Violence Scale is a reliable and easily comprehensible instrument mesuring percibed reasons of permanence with the aggressor. Its usefulness in both setting, clinical and social, will allow design with great effectiveness intervention strategies suitable for each case.
This study was supported in part by grant-58/05 from the Ministerio de Trabajo y Asuntos Sociales. Instituto de la Mujer.
Few studies have evaluated personality traits as a risk factor of postpartum depression (PPD). The Vulnerable Personality Style Questionnaire (VPSQ; Boyce et al. 2001), is a 9-item self-report scale developed to evaluate personality vulnerability to PPD with satisfactory psychometric properties. It assesses 9 personality dimensions: Coping, Nervy, Timidity, Sensitivity, Worrier, Obsessive, Volatility Organized and Expressive.
To study the vulnerable personality style in a Spanish postpartum sample.
A case-control study: 145 PPD women visited at the Psychiatry Perinatal Unit were compared to 203 healthy women from a postpartum population based study. All women were assessed with the VPSQ (Spanish adaptation), the Edinburgh Postnatal Depression Scale and the Structured Clinical Interview (DSM-IV) axis I. Personality traits were evaluated after full clinical remission. The study was approved by the Institution board.
Univariated analysis showed that women with PPD obtained higher scores (p<.000) in seven VPSQ personality dimensions: Coping, Nervy, Timidity, Sensitivity, Worrier, Obsessive, and Volatility, as well as the VPSQ total score (p<.000). Personal history of depression (p<.000) was also associated with PPD. In the logistic regression analysis; an increase of one point on the VPSQ total score increased the OR in 1.151 fold (95%CI:1.095-1.210) the association with PPD. Other variables associated were age and personal history of depression. The Hosmer-Lemershow test (p=.706) indicated the goodness-of-fit of the model.
Women with PPD had higher scores in the Vulnerable Personality Style Questionnaire. They were more nervous, timid, sensitive, obsessive, worried, angry and cope poorly than healthy postpartum women.
To examine the postpartum thyroid dysfunction (PPTD) and positive thyroid antibodies (Ab+) frequency in the Postpartum Depression (PPD) and to investigate if the PPD patients subgroup with PPTD and/or Ab+ have different characteristics.
Eighty one (N=81) patients with PPD, according with DSM-IV criteria, were included. Thyroid function (Free T3, Free T4,TSH), autoimmune status of the thyroid (Thyroperoxidasa antibodies, Thyroglobulin antibodies) and severity of depression (EPDS and 21-item Hamilton scales), were assessed joint with other several demographics, psycho-social and reproductive variables.
Twenty per cent of the patients with PPD had positive thyroid antibodies and 14% present PPTD. Prior history of early stressors in the PPD patients were significantly related with the presence of Ab+: the presence of childhood maltreatments and/or sexual abuse increased thirteen times the probability of Ab+ (OR: 13,01, 95% CI, 2.01-84.02). Greater number of total stressors were associated with Ab+ (p< 0,030), and Ab+ women showed a higher average of total stressors (2,1) than antibody negative women (1,52). Depressed women with PPTD had positive correlation with previous depressive episodes (p< 0,008).
The depressed postpartum women with dysregulation of pituitary-thyroid axis have more early childhood stressors and previous depressive episode. The implication of the inmunitary system and the HPT axis in the etiopathogenesis of the PPD through the activation of the response in front to stress is discussed.
Metabolic Syndrome (MS) is constituted by a set of specific metabolic alterations being postulated that the main dysfunction is insulin resistance. Estimates point to higher prevalence of MS in bipolar patients, between 30 to 35%. Cost-effective screening methods, not recurring to blood test, have been researched.
Analyse knowledge and importance given to MS in bipolar patients. Test the viability of MS screening without blood tests.
Observational, cross-sectional study. Random sample of 15 adult bipolar patients, in euthymic phase. Semi-structured interview, YMRS, HAMD were applied. MS diagnosis investigated according to the International Diabetes Federation (IDF) criteria. MS screening was defined positive if blood pressure ≥ 130/85 or anti-hypertensive medication and abdominal perimeter > 90 in males or > 80 in females. A questionnaire about knowledge, attitudes and concerns on MS was applied.
14 patients completed the investigation protocol. Five (36%) met IDF criteria for metabolic syndrome. Screening sensitivity was 80% and specificity 78%. Twelve patients (80%) were overweigh or obese. Mean IMC in patients that met IDF criteria for MS was 30 while in the other group mean IMC was 26. Only 3 (20%) have ever heard about MS, but the majority of the patients were concerned, in decreasing order, about weight gain, blood pressure cholesterol and hyperglycemia control.
Although limited by small sample size, this study strengthens the idea that MS screening can be effective in clinical practice, it also indicates the need to educate BP patients about MS and to prevent overweight.
The prevalence of mood disorders (anxiety and depression) during pregnancy seems to be similar to the women of the same group without pregnancy. Women with recurrent depression and euthimic women who discontinued antidepressants medication during pregnancy are particularly at high risk for depressive illness. Data about perinatal effects of SSRI antidepressants are gradually accumulating and are controversial. Two meta-analyses and some controlled studies don't find increased risk for major malformations in SSRI-exposed newborn. However, other studies find an increased risk of congenital malformations, poor birth outcomes and neonatal complications.
Neonatal morbidity in infant newborn of women treated with antidepressant drugs.
We examine the relation between the pharmacological treatment of the maternal anxiety/depression during the pregnancy and acute morbidity in infant newborns.
Materials and Methods
Study group of 66 infant newborn of pregnant women with a diagnoses of major depressive episode or defined anxiety disorders according to DSM-IV, who were in treatment with antidepressant drugs during pregnancy. Control group: 120 newborn of healthy pregnant women, who did not receive any treatment, and were contemporary of the same gestational age and sex. Criteria of exclusion: demonstrated toxic consumption (alcohol, cocaine, cannabis, opiates, drug of synthesis). Studied variables: Type of childbirth and analgesia; weight and age of gestation; pH of umbilical artery and Apgar test; presence of malformations; morbidity; feeding; withdrawal syndrome.
Infant newborn of mothers exposed to the antidepressant treatment suffered from more pathology than those of the control group (16/66 vs. 14/114; 24.2% vs.12.3%; p=0.038). Two smaller malformations in the study group were observed, a preauricular appendix (group A) and one moderate pielocilicilar ectasy (group C), both in mothers who received paroxetine (2/60; 3.3% vs. 0/114; 0%, p=0.05, Fisher p=0.118, NS). Only one infant newborn displayed compatible clinical signs with moderate withdrawal syndrome (irritability, vomits) from a mother treated with venlafaxine. No case of convulsions was observed. Breast feeding was less frequent in the group of antidepressant treated mothers (38/66, 57.6% vs. 86/116, 74,1%, p=0.032).
The treatment with antidepressant drugs during pregnancy is necessary for some women. The clinician must weigh the relative risks of various treatment options and take into account individual patient wishes. Although the antidepressant drugs suppose an increased risk for the newborn, it could be assumable for the benefit that represents maintain the mother in an euthimic situation.
We propose to discuss the clinical management, as well as, the accuracy of the psychiatric and obstetric controls to minimize the neonatal complications.
