RESUMEN

Onjective: Climate change and environmental pollution have known health effects. The recently introduced inflation reduction act (IRA) by the United States government includes funding initiatives to curb climate change, and reduce environmental pollution, in line with the nationally determined contribution (NDC) plan (40-50 % reduction in greenhouse gas [GHG] emissions by 2030, as compared with 2005). The projected cardiovascular health benefits of the IRA driven climate actions to achieve the NDC goals are not known. Methods: We used the Energy Policy Simulator (EPS), a simulation algorithm based on systems dynamics modelling estimating the impact of various energy policies, to model the impact of achieving NDC targets in the United States on health outcomes by 2050. We further investigated race-specific impact on mortality (absolute and relative) by 2050.We estimated the projected reduction in six adverse health outcomes between 2022 and 2050: asthma attacks, non-fatal heart attacks, hospital admissions, respiratory symptoms and bronchitis, lost workdays, and deaths. Results: Achievement of NDC targets by 2050 will result in 987,415 avoided asthma attacks, 41,565 avoided nonfatal heart attacks, 18,993 avoided hospital admissions, 1,493,010 avoided respiratory symptoms and bronchitis, 3,317,250 avoided lost workdays, and 32,659 avoided deaths (22,839 among white individuals, 4993 among Black individuals, 2801 among Asian individuals, and 2026 among other/multirace individuals). By 2050, minority racial groups had higher relative change in avoided deaths (white -0.74 %, Black -1.01 %, Asian -1.24 %, and other/multirace -1.75 %). Similarly, Hispanics/latinos higher relative reductions in deaths (-1.4 %) compared with non-Hispanic/Latinos (-0.7 %) by 2050. Conclusion: The IRA facilitated achievement of NDC GHG reduction goals by 2050 would result in substantial number of avoided adverse health outcomes and death. Racial and ethnic minorities are expected to have the largest relative reductions in deaths by 2050. The current report underscores the importance of continued climate action investment irrespective of political differences. The appreciation of this aspect of the IRA may be more important to overall preservation of health, beyond the reduction in medication costs.

RESUMEN

Background: Symptom accommodation by family members (FMs) of individuals with posttraumatic stress disorder (PTSD) includes FMs' participation in patients' avoidance/safety behaviours and constraining self-expression to minimise conflict, potentially maintaining patients' symptoms. The Significant Others' Responses to Trauma Scale (SORTS) is the only existing measure of accommodation in PTSD but has not been rigorously psychometrically tested.Objective: We aimed to conduct further psychometric analyses to determine the factor structure and overall performance of the SORTS. Method: We conducted exploratory and confirmatory factor analyses using a sample of N = 715 FMs (85.7% female, 62.1% White, 86.7% romantic partners of individuals with elevated PTSD symptoms).Results: After dropping cross-loading items, results indicated good fit for a higher-order model of accommodation with two factors: an anger-related accommodation factor encompassed items related largely to minimising conflict, and an anxiety-related accommodation factor encompassed items related primarily to changes to the FM's activities. Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction, although the factors showed somewhat distinct associations. Item Response Theory analyses indicated that the scale provided good information and robust coverage of different accommodation levels.Conclusions: SORTS data should be analysed as both a single score as well as two factors to explore the factors' potential differential performance across treatment and relationship outcomes.


We examined the Significant Others' Responses to Trauma Scale (SORTS), a measure of symptom accommodation in PTSD, among a large sample of family members.As measured by the SORTS, accommodation in PTSD could be broken down into two aspects: anger-related accommodation and anxiety-related accommodation.Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction.

RESUMEN

BACKGROUND: Nearly 50% of ST elevation myocardial infarction (STEMI) patients have multivessel coronary artery disease. The optimal selection of non-culprit lesions for complete revascularization is a matter of current debate. Little is known about the predictive value of myocardial perfusion study (MPS) in this scenario. METHODS: We enrolled 49 STEMI patients (61.5 ± 10.3 years) with at least one major non-culprit lesion (50-90%) other than left main coronary artery lesions. Overall 63 non-infarct- related artery (IRA) stenoses (65.2 ± 11.9%) were recommended for further evaluation using Fractional Flow Reserve (FFR) measurement as is standard in our institution. Prior to FFR, all patients were scheduled for non-invasive MPS using single-photon emission computed tomography (SPECT). Both FFR and MPS were performed 4-8 weeks after STEMI with MPS preceding FFR within no more than 48 hours. An FFR value of ≤0.80 was considered significant and guided the final revascularization strategy. The results of MPS were correlated to FFR as well as to the clinical and angiographic characteristics of both culprit and non-infarct-related lesions. RESULTS: Based on FFR, 30 out of 63 stenoses (47.6%) in 27 patients were considered hemodynamically significant (FFR 0.69 ± 0.08, range 0.51-0.79) compared to residual 33 stenoses considered negative (FFR 0.87 ± 0.04, range 0.81-0.96). The MPS revealed abnormal myocardium (23.6% average, range 5-56%) in 21 patients (42.8%). Among those patients, only 9 showed the evidence of ischemic myocardium (average 10.8%, range 4-18%) with low sensitivity of MPS in predicting positive FFR. Besides that, higher proportion of patients (71.4% vs. 42.9%, P=0.047) with overall lower FFR values (0.73 vs. 0.80, P=0.014, resp.) in non-IRAs as well as higher proportion of patients with more severely compromised flow in IRAs (P=0.048) during STEMI had MPS-detected abnormal myocardium. CONCLUSION: In STEMI patients with multivessel coronary artery disease, we observed rather weak correlation between MPS using SPECT and invasive hemodynamic measurement using FFR in ischemia detection.

RESUMEN

AIM: This study aimed to overproduce industrially relevant and safe bio-compound trans-cinnamic acid (tCA) from Photorhabdus luminescens with deletion strategies and homologous expression strategies that had not been applied before for tCA production. METHODS AND RESULTS: The overproduction of the industrially relevant compound tCA was successfully performed in P. luminescens by deleting stlB (TTO1ΔstlB) encoding a cinnamic acid CoA ligase in the isopropylstilbene pathway and the hcaE insertion (knockout) mutation (hcaE::cat) in the phenylpropionate catabolic pathway, responsible for tCA degradation. A double mutant of both stlB deletion and hcaE insertion mutation (TTO1DM ΔstlB-hcaE::cat) was also generated. These deletion strategies and the phenylalanine ammonium lyase-producing (PI-PAL from Photorhabdus luminescens) plasmid, pBAD30C, carrying stlA (homologous expression mutants) are utilized together in the same strain using different media, a variety of cultivation conditions, and efficient anion exchange resin (Amberlite IRA402) for enhanced tCA synthesis. At the end of the 120-h shake flask cultivation, the maximum tCA production was recorded as 1281 mg l-1 in the TTO1pBAD30C mutant cultivated in TB medium, with the IRA402 resin keeping 793 mg l-1 and the remaining 488 mg l-1 found in the supernatant. CONCLUSION: TCA production was successfully achieved with homologous expression, coupled with deletion and insertion strategies. 1281 mg l-1is the highest tCA concentration that achieved by bacterial tCA production in flask cultivation, according to our knowledge.

RESUMEN

INTRODUCTION: APC-associated polyposis is a rare hereditary disorder characterized by the development of multiple adenomas in the digestive tract. Individuals with APC-associated polyposis need to be managed by specialized multidisciplinary teams in dedicated centers. AREAS COVERED: The study aimed to review the literature on Familial adenomatous polyposis (FAP) to provide an update on diagnostic and surgical management while focusing on strategies to minimize the risk of desmoid-type fibromatosis, cancer in anorectal remnant, and postoperative complications. FAP individuals require a comprehensive approach that includes diagnosis, surveillance, preventive surgery, and addressing specific extracolonic concerns such as duodenal and desmoid tumors. Management should be personalized considering all factors: genotype, phenotype, and personal needs. Total colectomy and ileo-rectal anastomosis have been shown to yield superior QoL results when compared to Restorative Procto colectomy and ileopouch-anal anastomosis with acceptable oncological risk of developing cancer in the rectal stump if patients rigorously adhere to lifelong endoscopic surveillance. Additionally, a low-inflammatory diet may prevent adenomas and cancer by modulating systemic and tissue inflammatory indices. EXPERT OPINION: FAP management requires a multidisciplinary and personalized approach. Integrating genetic advances, innovative surveillance techniques, and emerging therapeutic modalities will contribute to improving outcomes and quality of life for FAP individuals.

RESUMEN

This study presents two modified polymers for Cu2+ ion removal from aqueous media. Shredded maize stalk (MC) and a strong-base anionic resin (SAX) were modified with indigo carmine (IC) in order to obtain two different complexing polymers, i.e., IC-MC and SAX-IC. Initially, the complex reaction between IC and Cu2+ in the solution was studied. Additionally, the complex formation Cu2+-IC in liquid solutions was evaluated at different pH ranges of 1.5, 4.0, 6.0, 8.0, and 10.0, respectively. For Cu2+ ions, adsorption onto the IC-MC and IC-SAX batch experiments were conducted. The contact time for evaluating the optimum adsorption for Cu2+ ions on the complexing materials was established at 1 h. Efficient Cu2+ ion adsorption on the IC-MC and SAX-IC at pH = 10 was achieved. The adsorption of Cu2+ ions depends on the quantity of IC retained on MC and SAX. At 2.63 mg IC/g MC(S4) and 22 mg IC/g SAX(SR2), a high amount of Cu2+ ion adsorption was reported. The highest adsorption capacity (Qe) of IC-MC was obtained at 0.73 mg/g, and for IC-SAX, it was attained at 10.8 mg/g. Reusability experiments were performed using the HCl (0.5 M) solution. High regeneration and reusability studies of IC-MC and IC-SAX were confirmed, suggesting that they can be used many times to remove Cu2+ ions from aqueous matrices. Therefore, the development of complexing materials could be suitable for Cu2+ ion removal from wastewater.

RESUMEN

BACKGROUND: The optimal revascularization strategy for non-culprit vessels is still up for debate nowadays, particularly when it comes to individuals with different Killip classes. Therefore, the aim of our study was to investigate whether multivessel revascularization, as compared with infarct-related artery (IRA) alone revascularization, improves long-term prognosis in patients who have experienced an acute myocardial infarction (AMI) and have multivessel coronary artery disease (CAD). METHODS: A retrospective analysis was conducted on clinical data from 646 patients who presented with AMI and multivessel CAD at Beijing Chaoyang hospital between November 2014 and November 2020. Based on various revascularization strategies, patients were categorised into two groups: IRA-only revascularization (n = 416) and multivessel revascularization (n = 230). The primary endpoint was cardiovascular death. RESULTS: In the following 60.6 months (60.6 ± 23.9), the primary endpoint occurred in 3% of the multivessel revascularization group versus 9.6% in the IRA-only revascularization group (HR 0.284, CI 0.120-0.669, p = 0.002). For the Killip I-II patients (n = 533), the primary endpoint occurred in 2.6% of the multivessel revascularization group versus 9.5% in the IRA-only revascularization group (HR 0.236, CI 0.083-0.667, p = 0.003). For Killip III-IV patients (n = 113), there was no significance differences in the primary endpoint. After using the inverse probability weighted method, the benefit of complete revascularization was consistently observed. CONCLUSIONS: Multivessel revascularization significantly reduced the incidence of cardiovascular death for patients presenting with AMI and multivessel CAD, particularly for Killip I-II patients. There were no significant differences in the primary outcome across the groups of patients with Killip III-IV.

RESUMEN

Acute respiratory failure (ARF) is a leading cause, along with sepsis, of admission to the intensive care unit (ICU) of patients with active cancer. Presenting variable clinical severity, ARF in onco-hematological patients has differing etiologies, primarily represented by possibly opportunistic acute infectious pneumonia (de novo hypoxemic ARF), and decompensation in chronic cardiac or respiratory diseases (e.g., acute pulmonary edema or exacerbated chronic obstructive pulmonary disease). In these patients, orotracheal intubation is associated with a doubled risk of in-hospital mortality. Consequently, over the last three decades, numerous researchers have attempted to demonstrate and pinpoint the precise role of non-invasive ventilation (NIV) in the specific context of ARF in onco-hematological patients. While the benefits of NIV in the management of acute pulmonary edema or alveolar hypoventilation (hypercapnic ARF) are well-demonstrated, its positioning in de novo hypoxemic ARF is debatable, and has recently been called into question. In the early 2000s, based on randomized controlled trials, NIV was recommended as first-line treatment, one reason being that it allowed significantly reduced use of orotracheal intubation. In the latest randomized studies, however, the benefits of NIV in terms of survival orotracheal intubation have not been observed; as a result, it is no longer recommended in the management of de novo hypoxemic ARF in onco-haematological patients.

RESUMEN

Background: Maladaptive trauma appraisal plays an important role in the development and maintenance of posttraumatic stress disorder (PTSD). While studies have demonstrated the effectiveness of exposure and cognitive treatments for PTSD symptomatology, the effect of such treatments on specific trauma appraisals is still not well understood.Objective: The study investigated the effect of an exposure and a cognitive restructuring internet-based treatment on specific trauma appraisals in Arabic-speaking participants with PTSD.Method: 334 participants received either an exposure (n = 167) or a cognitive restructuring (n = 167) internet-based treatment. PTSD symptom severity (PCL-5) and specific trauma appraisals (TAQ) were assessed at pre- and post-treatment. Changes in specific trauma appraisals within and between the two treatments were analyzed using multi-group change modelling. Associations between changes in PTSD symptom severity and changes in trauma appraisals were evaluated using Pearson product-moment correlation. For both treatments, participants with versus without reliable improvement were compared regarding changes in specific trauma appraisals using Welch tests. Analyses were performed on 100 multiple imputed datasets.Results: Both treatments yielded significant changes in shame, self-blame, fear, anger, and alienation (all ps < .001). Changes in betrayal were only significant in the cognitive restructuring treatment (p < .001). There was no evidence of differences between treatments for any specific trauma appraisal. Changes in PTSD symptom severity were significantly associated with changes in trauma appraisals (all ps < .001). In both treatments, participants who experienced reliable improvement in PTSD symptom severity showed significantly larger pre- to post-treatment changes in specific trauma appraisals compared to those without reliable improvement. Again, differences in betrayal were only significant in the cognitive restructuring treatment.Conclusions: The findings indicate that both treatments are effective in reducing trauma appraisals in Arabic-speaking people with PTSD. Changes in trauma appraisal seem to be associated with changes in PTSD symptomatology.Trial registration: German Clinical Trials Register identifier: DRKS00010245.


Exposure and cognitive restructuring treatment in Arabic-speaking individuals with PTSD yield significant changes in shame, self-blame, fear, anger, and alienation.Changes in PTSD symptoms are positively associated with changes in specific trauma appraisals.There is no evidence of differences between both treatments for any specific trauma appraisal.

RESUMEN

AIM: Ileorectal anastomosis (IRA) following total abdominal colectomy (TAC) allows for resortation of bowel continuity but prior studies have reported rates of anastomotic leak (AL) to be as high as 23%. We aimed to report rates of AL and complications in a large cohort of patients undergoing IRA. We hypothesized that AL rates were lower than previously reported and that selective use of diverting loop ileostomy (DLI) is associated with decreased AL rates. METHOD: Patients undergoing TAC or end-ileostomy reversal with IRA, with or without DLI, between 1980 and 2021 were identified from a prospectively maintained institutional database and retrospectively analysed. Redo IRA cases were excluded. Short-term (30-day) surgical outcomes were collected using our database. AL was defined using a combination of imaging and, in the case of return to the operating room, intraoperative findings. RESULTS: Of 823 patients in the study cohort, DLI was performed in 27% and performed more frequently for constipation and inflammatory bowel disease. The overall AL rate was 3% (1% and 4% in those with and without DLI, respectively) and diversion was found to be protective against leak (OR 0.28, 95% CI 0.08-0.94, p = 0.04). However, patients undergoing diversion had a higher overall rate of postoperative complications (51% vs. 36%, p < 0.001) including superficial wound infection, urinary tract infection, dehydration, blood transfusion and portomesenteric venous thrombosis (all p < 0.04). CONCLUSION: Our study represents the largest series of patients undergoing IRA reported to date and demonstrates an AL rate of 3%. While IRA appears to be a viable surgical option for diverse indications, our study underscores the importance of careful patient selection and thoughtful consideration of staging the anastomosis and temporary faecal diversion when necessary.

RESUMEN

OBJECTIVE: To evaluate the diagnostic performance of FENa (Fractional excretion of sodium), FEK (fractional excretion of potassium) and uSID (urinary strong ion difference) in predicting pAKI in sepsis and septic shock. DESIGN: Retrospective cohort study. SETTING: Two intensive care units in Argentina. PATIENTS: Adult patients with a confirmed diagnosis of sepsis or septic shock and AKI, and had a urinary biochemistry within 24h of the AKI diagnosis. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: We evaluated the diagnostic accuracy of FENa, FEK and uSID through a ROC (Receiver Operating Characteristic) curve analysis. RESULTS: 80 patients were included. 40 patients presented pAKI. pAKI group had higher APACHE, SOFA score, and mortality rate. In the ROC curve analysis, uSID had no diagnostic utility (AUC=0.52, p=0.69). FENa presented moderate accuracy showing an AUC of 0.71 (95% CI 0.60-0.83; p=0.001), while FEK presented low accuracy with an AUC of 0.69 (95% CI 0.57-0.80; p=0.04). The optimal Youden point for identifying pAKI was at a FENa higher than 0.51 % with a specificity of 72.5% and a sensitivity of 65.0%. In the case of FEK, a value higher than 21.9 % presented the best relation, with a specificity of 67.5% and a sensitivity of 65.0%. CONCLUSIONS: urine biochemistry interpretation in septic patients must be revised. FENa and FEK are related to the severity of AKI and could be helpful complementary tools for diagnosing pAKI.

RESUMEN

BACKGROUND: In Iran, half of all mortalities and 79% of those induced by noncommunicable diseases are attributed to cardiovascular diseases. In Iran, due to the high rate of noncommunicable diseases, a modified program (PEN) called Ira-PEN was integrated into the primary care program in health centers. The Ira-PEN program is adapted from the comprehensive WHO-PEN program to estimate the 10-year risk of cardiovascular diseases to control the main risk factors of noncommunicable diseases nationally. This study was conducted to investigate the process of service provision to determine the information needs and the necessary interventions in the comprehensive health service centers of Ardabil Province. MATERIALS AND METHODS: The present descriptive and analytical study was conducted in the Ardabil University of Medical Sciences. It used the data available in the registration system of the Health Network. The research population consisted of all people aged between 40 and 80 who visited the comprehensive health service centers to perform risk assessment of cardiovascular strokes in the province from 2018 to the end of 2021. The collected data were added to Excel. FORCAST function was used to predict the future through a linear regression analysis. To compare the final results, which is actually a reduction in mortality due to cardiovascular diseases, the difference test of two mortality rates due to cardiovascular diseases was used in 2018 and 2021. Test of two death proportions was performed through z test and Minitab21 Software. RESULTS: The prevalence of cardiovascular disease risk factors was as follows: history of heart attack (0.59%), history of stroke (0.51%), history of diabetes (7.9%), history of high blood pressure (15.7%), and history of prediabetics (12.8%). The probability of suffering from lipid disorder was 26.4% and BMI > 30 was 32.4%. The risk factors of hypertension, abdominal obesity, and smoking showed a decrease in the measurement of disease risk factors during 4 years. CONCLUSIONS: Identification of the common risk factors in the region helps to focus interventions on effective prevention and treatment measures and adopt evidence-based policies in order to reduce these risk factors. Since the investigated risk factors are rooted in inappropriate behaviors and lifestyles, by modifying these behaviors and changing lifestyles, their prevalence can be reduced and reducing these risk factors will lead to a reduction in the prevalence of cardiovascular diseases.

RESUMEN

El acoso escolar y el ciberacoso se presentan como comporta-mientos de riesgo durante la adolescencia. Aunque se ha reconocido una importante relación entre ambos fenómenos, aspectos referidos a su preva-lencia, la semejanza y diferencia entre uno y otro, la transferencia de roles, así como los aspectos emocionales, sociales y morales asociados aún están sin resolver. El objetivo fue explorar los perfiles de implicación en acoso y ciberacoso a través de un análisis de clases latentes y examinar su asocia-ción con desconexión moral, ajuste social y normativo y rumiación de la ira. Se presenta un estudio longitudinal en dos tiempos con 3,006 escolares de secundaria (Medad= 13.53; 51.9% chicas). Se utilizaron autoinformes ampliamente validados en la población de referencia. Los resultados mos-traron cuatro clases latentes: no implicados, víctimas-cibervíctimas, agreso-res victimizados y totalmente implicados. Análisis de regresión logística identificaron un bajo ajuste social en los totalmente implicados, bajo ajuste normativo y alta desconexión moral en perfiles mixtos, y alta rumiación de la ira en todos los perfiles de implicación, principalmente en agresores vic-timizados. Se discuten estos resultados en términos de su valor para com-prender los matices que distinguen el acoso y ciberacoso, de la existencia de roles puros y mixtos y de las variables emocionales, sociales y morales asociadas.(AU)


Bullying and cyberbullying are risky behaviours which normally occur during adolescence. Although an important relationship has been recognized between the two phenomena, issues related to their prevalence, the similarity and difference between them, the transfer of roles, as well as the emotional, social, and moral aspects associated with them, remain un-resolved. The aim of this study was to explore the roles ofinvolvement in bullying and cyberbullying through an analysis of latent classes, and exam-ine their association with moral disengagement, social and normative ad-justment, and anger rumination. The study had a two-stage longitudinal de-sign, with 3,006 secondary school students (Mage= 13.53; 51.9% girls), us-ing extensively validated self-reports in the reference population. The re-sults showed four latent classes: uninvolved, victim-cybervictim, bully-victim and wholly involved. Logistic regression analyses identified a low social adjustment in those wholly involved, low normative adjustment and high moral disengagement in mixed profiles, and high anger rumination in all involvement profiles, mainly in bully-victim. These results are discussed in terms of their value in understanding the distinctions between bullying and cyberbullying, the existence of pure and mixed roles, and the associat-ed emotional, social, and moral variables.(AU)

RESUMEN

La sociedad postmoderna ha transformado muchas conductas familiares, entre ellas, la comunicación familiar y el hábito de comer en familia, práctica que ha disminuido en España en las últimas décadas, al tiempo que han aumentado la agresividad y las conductas violentas en adolescentes. El objetivo principal de este trabajo fue determinar la relación de la frecuencia de comidas en familia con la comunicación familiar y con la agresividad en población adolescente. Participaron 1117 adolescentes (51.1% mujeres y 48.9% varones), entre 14 y 18 años (M = 16.20; DT = 1.31), procedentes de 23 centros educativos, 10 grados universitarios y 18 centros específicos de menores de Castilla y León (España). Se utilizó el Cuestionario de Agresividad de Buss y Perry (BPAQ) y la Escala de Comunicación Familiar (FCS). Los resultados muestran que la ausencia de comidas en familia está asociada con un descenso de la comunicación familiar y un aumento de la agresividad física, la ira y la hostilidad del adolescente. Si comer en familia va acompañado de comunicación familiar, una mayor frecuencia de comidas en familia se relaciona con una disminución de las tres dimensiones mencionadas de la agresividad. Sin embargo, si se deja al margen la influencia de la comunicación familiar, comer frecuentemente en familia se relaciona con una reducción de la agresividad (física, ira y hostilidad), pero comer siempre en familia está asociado con un nuevo incremento de la agresividad física y hostilidad. Los hallazgos revelan la importancia de potenciar las comidas en familia y la comunicación familiar. (AU)


Postmodern society has modified many family behaviors, among them, family communication and the habit of eating together as a family, a practice that has decreased in Spain in the last decades while aggressiveness and violent behaviors in adolescents have increased. The main objective of the present study was to determine the relationship between the frequency of family meals with family communication and with aggression in adolescent population. 1117 adolescents (51.1% female and 48.9% male), aged between 14 and 18 years (M = 16.20; SD = 1.31), from 23 educational centers, 10 university grades, and 18 specific juvenile centers in Castilla y León (Spain) participated in the study. The Buss and Perry Aggression Questionnaire (BPAQ) and the Family Communication Scale (FCS) were used. The results show that the absence of family meals is associated with a decrease in family communication and an increase in adolescent physical aggression, anger, and hostility. If family meals are accompanied by family communication, a higher frequency of family meals is associated with a decrease in the three aforementioned dimensions of aggression. However, if the influence of family communication is left out, eating frequently as a family is related to a reduction in physical aggression, anger and hostility, but always eating as a family is associated with a new increase in physical aggression and hostility.

RESUMEN

El trastorno de conducta grave es un notable problema social y de salud mental en población infantil y adolescente. Aquí se presentan los resultados de una investigación cuantitativa de nivel descriptivo, que tuvo como objetivo general realizar una caracterización de la agresividad en un grupo de adolescentes con este tipo de trastorno. El estudio se desarrolló con jóvenes de un centro de internamiento preventivo que se encontraban en proceso de judicialización, aún no sancionados, pero privados de la libertad. Se seleccionaron por conveniencia 115 hombres, a los que se les aplicaron cinco instrumentos de medición: el Inventario de Motivos para la Agresión, el Inventario de Situaciones y Comportamientos Agresivos, el Cuestionario de Agresión de Buss-Perry, el Cuestionario de Agresividad Proactiva y Reactiva, y la Escala de Agresividad Apetitiva. El principal motivo para la agresión era conseguir algo que querían, eran agresivos sin que hubiese algún motivo, expresaban frecuentemente su ira, amenazaban a personas conocidas, se enojaban cuando tenían desacuerdos, creían que los demás se burlaban de ellos a sus espaldas, se sentían bien después de agredir física o verbalmente a alguien, portaban armas para usarlas en peleas y consideraban que pelear era lo único que querían hacer en la vida.


Severe conduct disorder is a notable social and mental health problem in child and adolescent population. Here we present the results of a descriptive quantitative research with the general objective of characterizing aggressiveness in a group of adolescents with this type of disorder. The study was carried out with young people from a preventive detention center who were in the process of judicialization, not yet sanctioned, but deprived of their liberty. A total of 115 males were selected by convenience and five measurement instruments were applied: the Motives for Aggression Inventory, the Aggressive Situations and Behavior Inventory, the Buss-Perry Aggression Questionnaire, the Proactive and Reactive Aggressiveness Questionnaire, and the Appetitive Aggressiveness Scale. The main motive for aggression was to get something they wanted, they were aggressive for no reason, they frequently expressed anger, threatened people they knew, got angry when they had disagreements, believed that others made fun of them behind their backs, felt good after physically or verbally assaulting someone, carried weapons to use in fights, and considered that fighting was the only thing they wanted to do in life.

RESUMEN

ABSTRACT Aim: This study aims to investigate the 90-day and 1-year mortality and the affecting factors of mortality in patients who have started dialysis treatment for the first time. Methods: Patients who started intermittent hemodialysis for the first time in the hemodialysis unit were evaluated. Patients who received hemodialysis treatment for any reason before, patients who underwent hemodialysis due to methyl alcohol, lithium, or mushroom poisoning, and patients who started dialysis in the intensive care unit were excluded from the study. The clinical and laboratory data were obtained from the patients, at admission time, from the electronic data record system and patients' charts.Univariate and multivariate logistic regression analyses were used to identify predictive factors for 90-days and 1-year mortality-dependent variables. Results: 229 patients were included in this study. 133(58.8%) of the patients were male, 96(41.9%) were female, and the median age was 64 years. While 166 patients had pre-existing renal disease, 63 patients had no prior renal disease. The number of patients who died within 90 days, which refers to short-term mortality, was 49 (21.4%). 73 patients (31.9%) died in one year (long-term mortality). At the end of one year, 38% of the whole group of patients continued receiving renal replacement therapy, while 10% of all CKD patients had not a requirement of dialysis, and only 9.17% of the patients had renal recovery. In the multivariate analysis established for short-term mortality, the following parameters showed significant predictive features: ejection fraction (OR = 3.80, 95% CI: 1.05-13.72, p=0.042), CRP (OR = 0.20, 95% CI: 0.04-0.92, p= 0.039), age (OR = 0.21, 95% CI: 0.05-0.91, p= 0.038), and diastolic blood pressure (OR = 0.08, 95% CI: 0.02-0.28, p< 0.001). The multivariate analysis for long-term mortality indicated that systolic blood pressure (OR = 0.26, 95% CI: 0.08-0.82, p= 0.022), diastolic blood pressure (OR = 0.21, 95% CI: 0.68-0.66, p= 0.008), and potassium (OR = 0.27, 95% CI: 0.10-0.70, p= 0.007) were independent predictive markers. Conclusion: Patients with CKD who have not yet started hemodialysis treatment should be followed closely, as hypervolemia, hypotension, and hemodynamic instability increase the risk of death, according to our study. In addition, we recommend that clinical conditions such as hemodynamic instability or sepsis, which may cause hypotension in AKI-D, should be addressed as soon as possible, and optimizing the fluid-electrolyte balance carefully in those patients we determined to be at risk.


RESUMEN Objetivo: Este estudio tiene como objetivo investigar la mortalidad a 90 días y 1 año y los factores que afectan la mortalidad en pacientes que han iniciado tratamiento de diálisis por primera vez. Métodos: Se evaluaron pacientes que iniciaron hemodiálisis intermitente por primera vez en la unidad de hemodiálisis. Se excluyeron del estudio los pacientes que recibieron tratamiento de hemodiálisis por cualquier motivo anteriormente, los pacientes que se sometieron a hemodiálisis por intoxicación con alcohol metílico, litio o hongos y los pacientes que iniciaron diálisis en la unidad de cuidados intensivos. Los datos clínicos y de laboratorio se obtuvieron de los pacientes al momento del ingreso, del sistema de registro electrónico de datos y de las historias clínicas de los pacientes. Se utilizaron análisis de regresión logística univariados y multivariados para identificar factores predictivos para variables dependientes de mortalidad a 90 días y 1 año. Resultados: 229 pacientes fueron incluidos en este estudio. 133 (58,8%) de los pacientes eran hombres, 96 (41,9%) eran mujeres y la mediana de edad fue de 64 años. Mientras que 166 pacientes tenían enfermedad renal preexistente, 63 pacientes no tenían enfermedad renal previa. El número de pacientes que fallecieron dentro de los 90 días, que se refiere a la mortalidad a corto plazo, fue de 49 (21,4%). 73 pacientes (31,9%) fallecieron en un año (mortalidad a largo plazo). Al cabo de un año, el 38% de todo el grupo de pacientes continuaba recibiendo terapia de reemplazo renal, mientras que el 10% de todos los pacientes con ERC no requerían diálisis y solo el 9,17% de los pacientes presentaban recuperación renal. En el análisis multivariante establecido para la mortalidad a corto plazo, los siguientes parámetros mostraron características predictivas significativas: fracción de eyección (OR = 3,80, IC 95%: 1,05-13,72, p=0,042), PCR (OR = 0,20, IC 95%: 0,04 -0,92, p= 0,039), edad (OR = 0,21, IC 95%: 0,05-0,91, p= 0,038) y presión arterial diastólica (OR = 0,08, IC 95%: 0,02-0,28, p< 0,001). El análisis multivariado para la mortalidad a largo plazo indicó que la presión arterial sistólica (OR = 0,26, IC 95%: 0,08-0,82, p= 0,022), la presión arterial diastólica (OR = 0,21, IC 95%: 0,68-0,66, p= 0,008), y el potasio (OR = 0,27, IC 95%: 0,10-0,70, p= 0,007) fueron marcadores predictivos independientes. Conclusión: Los pacientes con ERC que aún no han iniciado tratamiento con hemodiálisis deben ser seguidos de cerca, ya que la hipervolemia, la hipotensión y la inestabilidad hemodinámica aumentan el riesgo de muerte, según nuestro estudio. Además, recomendamos que las condiciones clínicas como la inestabilidad hemodinámica o la sepsis, que pueden causar hipotensión en AKI-D, deben abordarse lo antes posible y optimizar cuidadosamente el balance de líquidos y electrolitos en aquellos pacientes que determinamos que están en riesgo.

RESUMEN

The paraneoplastic syndrome referred in the literature as non-islet-cell tumor hypoglycemia (NICTH) and extra-pancreatic tumor hypoglycemia (EPTH) was first reported almost a century ago, and the role of cancer-secreted IGF-II in causing this blood glucose-lowering condition has been widely established. The landscape emerging in the last few decades, based on molecular and cellular findings, supports a broader role for IGF-II in cancer biology beyond its involvement in the paraneoplastic syndrome. In particular, a few key findings are constantly observed during tumorigenesis, (a) a relative and absolute increase in fetal insulin receptor isoform (IRA) content, with (b) an increase in IGF-II high-molecular weight cancer-variants (big-IGF-II), and (c) a stage-progressive increase in the IGF-II autocrine signal in the cancer cell, mostly during the transition from benign to malignant growth. An increasing and still under-exploited combinatorial pattern of the IGF-II signal in cancer is shaping up in the literature with respect to its transducing receptorial system and effector intracellular network. Interestingly, while surgical and clinical reports have traditionally restricted IGF-II secretion to a small number of solid malignancies displaying paraneoplastic hypoglycemia, a retrospective literature analysis, along with publicly available expression data from patient-derived cancer cell lines conveyed in the present perspective, clearly suggests that IGF-II expression in cancer is a much more common event, especially in overt malignancy. These findings strengthen the view that (1) IGF-II expression/secretion in solid tumor-derived cancer cell lines and tissues is a broader and more common event compared to the reported IGF-II association to paraneoplastic hypoglycemia, and (2) IGF-II associates to the commonly observed autocrine loops in cancer cells while IGF-I cancer-promoting effects may be linked to its paracrine effects in the tumor microenvironment. Based on these evidence-centered considerations, making the autocrine IGF-II loop a hallmark for malignant cancer growth, we here propose the functional name of IGF-II secreting tumors (IGF-IIsT) to overcome the view that IGF-II secretion and pro-tumorigenic actions affect only a clinical sub-group of rare tumors with associated hypoglycemic symptoms. The proposed scenario provides an updated logical frame towards biologically sound therapeutic strategies and personalized therapeutic interventions for currently unaccounted IGF-II-producing cancers.

RESUMEN

Se plantearon dos objetivos: a) conocer cómo evolucionó la emoción de ira fundamentalmente y otros sentimientos y emociones, que el alumnado experimentó en la clase de Expresión Corporal, tras incluir prácticas orientales propias de las artes marciales; b) señalar prácticas físicas y estrategias utilizadas en la intervención que puedan disminuir la emoción de ira. 70 alumnos/as universitarios que cursan la asignatura de Expresión Corporal en el Grado de Ciencias de la Actividad Física y el Deporte participaron en el estudio. Se implementó una intervención de ocho sesiones, durante ocho semanas. Se recogió información a través de grupos de discusión y el diario de seguimiento del profesor. El análisis produjo tres categorías/temas: emociones, prácticas físicas y prácticas orientales y estrategias para disminución de la ira. Tras la intervención el alumnado experimentó más emociones positivas que negativas, aunque las negativas predominaron antes del comienzo de las sesiones. Se señala la música, los movimientos lentos, el silencio, el trabajo de respiración y la meditación como estrategias válidas para la disminución de la ira. (AU)


Foram traçados dois objetivos: a) conhecer como evolui fundamentalmente a emoção da raiva e outros sentimentos e emoções que os alunos vivenciaram na aula de Expressão Corporal após a inclusão de práticas orientais típicas das artes marciais; b) apontar práticas físicas e estratégias utilizadas na intervenção que podem reduzir a emoção da raiva. Participaram no estudo setenta estudantes universitários que frequentam a disciplina de Expressão Corporal na Licenciatura em Ciências da Atividade Física e do Desporto. Foi implementada uma intervenção de oito sessões, durante oito semanas. As informações foram coletadas por meio de grupos focais e diário do professor. A análise produziu três categorias/temas: emoções, atividades físicas e estratégias de redução da raiva. Após a intervenção, os alunos vivenciaram mais emoções positivas do que negativas, embora as negativas predominassem antes do início das sessões. Música, movimentos lentos, silêncio, respiração e meditação são apontados como estratégias válidas para reduzir a raiva. (AU)


Two objectives were set: a) know how the emotion of anger fundamentally evolves and other feelings and emotions that the students experienced in Body Expression class after including oriental practices typical of martial arts; b) point out physical practices and strategies used in the intervention that can reduce the emotion of anger. Seventy university students who are studying Body Expression in the Degree in Physical Activity and Sports Sciences participated in the study. An intervention of eight sessions was implemented, for eight weeks. Information was collected through focus groups and teache'rs diary. The analysis produced three categories/themes: emotions, physical activities, and anger reduction strategies. After the intervention, the students experienced more positive than negative emotions, although the negative ones predominated before the beginning of the sessions. Music, slow movements, silence, breath work, and meditation are pointed out as valid strategies for reducing anger. (AU)

RESUMEN

ABSTRACT. Due to the need for face-to-face administration of many cognitive screening tests, it is not always feasible to screen large-scale samples. Objective: This study aimed to assess the discriminant validity of the Persian version of Telephone Interview for Cognitive Status (P-TICS-m) and Mini-Mental State Examination in the middle-aged Iranian population. Methods: The P-TICS-m and MMSE were administered to 210 randomly selected middle-aged community-dwelling adults who had been registered in the Neyshabur Longitudinal Study on Ageing. Participants also underwent psychological examination by two neurologists to assess cognitive impairment based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. To evaluate the discriminant validity of P-TICS-m and MMSE with DSM-V criteria, the sensitivity, specificity, positive and negative predictive values (PPV and NPV), and positive and negative likelihood ratios (LR+ and LR−) were calculated. Results: The mean age of the participants was 59.6±6.8 years. The TICS and MMSE were highly correlated (r=0.635, p<0.001). The sensitivity, specificity, PPV, NPV, LR+, and LR− to discriminate cognitive impairment were, respectively, 83%, 92%, 68%, 96%, 10, and 0.182 for MMSE and 100%, 13%, 19%, 100%, 1.16, and 0 for TICS-m. The receiver operating characteristic curve analysis results showed no statistically significant differences between P-TICS-m and MMSE. Conclusions: Our findings indicate that the TICS-m test can be used as a screening tool instead of the MMSE. Due to the low specificity and low PPV of the TICS-m compared to MMSE, the diagnosis should be confirmed using definitive diagnostic tests when a subject is classified as having cognitive impairment.


RESUMO. Diante da necessidade de administração face a face de muitos testes de triagem cognitiva, nem sempre é viável rastrear amostras em grande escala. Objetivo: O objetivo deste estudo foi avaliar a validade discriminante da versão persa do Telephone Interview for Cognitive Status (TICS-m) e do Miniexame do Estado Mental (MMSE) na população iraniana de meia-idade. Métodos: A versão persa do TICS-m (P-TICS-m) e do MMSE foi administrada a 210 adultos de meia-idade residentes na comunidade e selecionados aleatoriamente, que haviam sido registrados no Neyshabur Longitudinal Study on Ageing. Os participantes também foram submetidos a exame psicológico por dois neurologistas para serem avaliados quanto ao comprometimento cognitivo com base nos critérios do Manual de Diagnóstico e Estatística de Transtornos Mentais (DSM-V). Para avaliar a validade discriminante do P-TICS-m e do MMSE com os critérios do DSM-V, foram calculados a sensibilidade, a especificidade, os valores preditivos positivo e negativo (PPV e NPV) e a razão de verossimilhança positiva e negativa (LR+ e LR-). Resultados: A média de idade dos participantes foi de 59,6±6,8 anos. O TICS e o MMSE foram altamente correlacionados (r = 0,635, p <0,001). A sensibilidade, a especificidade, o PPV, o NPV, a LR+ e a LR- do MMSE para discriminar comprometimento cognitivo foram 83, 92, 68, 96%, 10, 0,182; e, para TICS-m, foram 100, 13, 19, 100%, 1,16 e zero, respectivamente. Os resultados da análise da curva característica de operação do receptor (ROC) não mostraram diferenças estatisticamente significativas entre P-TICS-m e MMSE. Conclusões: Nossos achados mostram que o teste TICS-m pode ser utilizado como ferramenta de triagem em vez do MEEM. Por causa da baixa especificidade e do baixo PPV do TICS-m em relação ao MMSE, o diagnóstico deve ser confirmado por meio de testes diagnósticos definitivos quando um indivíduo é classificado como portador de comprometimento cognitivo.

RESUMEN

Las expresiones de amenaza son detectadas con rapidez y precisión, advirtiendo a quienes las observan de la presencia de un potencial peligro. Durante el proceso de detección, la expresión de sorpresa podría jugar un papel importante como clave de orientación en condiciones de incertidumbre donde se requiere una respuesta rápida y precisa. Con el objetivo de analizar este supuesto se plateó un experimento en el que participaron 70 sujetos que realizaron una tarea de señalización espacial, donde se utilizaron expresiones faciales de sorpresa (vs. neutra) como claves de orientación, y expresiones faciales de miedo, ira, alegría y neutras como estímulos objetivo. Los resultados mostraron un efecto facilitador de la expresión de sorpresa solo en la detección de la expresión de ira, reduciendo los tiempos de respuesta y el porcentaje de errores. Los datos apuntan a que la expresión de sorpresa, cuando se procesa como un estímulo independiente, podría facilitar la detección de aquellos estímulos que supongan una amenaza directa, como la expresión de ira, siendo esta distinción clave para entender en qué condiciones se detecta más eficazmente la expresión de ira respecto a otro tipo de expresiones.(AU)


Threatening expressions are detected quickly and accurately, warning the observer of the presence of a potential danger. During the de-tection process, a facial expression of surprise could play an important role as a cue for orientation in conditions of uncertainty that call for a swift and precise response. With a view to analysing this contingency, an experiment was conducted in which 70 subjects undertook a spatial cueing task that involved facial expressions of surprise (vs. neutral ones) as orientation cues, and facial expressions of fear, anger and happiness as target stimuli. The results revealed a priming effect of the expression of surprise solely in the detection of the expression of anger, reducing response times and the percentage of errors. Thedata indicate that the expression of surprise, when processed as an independent stimulus, could prime the detection of those stimuli that constitute a direct threat, such as the expression of anger, with this being a crucial distinction for understanding the circumstances in which the expression of anger is detected more effectively than other kinds of expressions.(AU)
