Effectiveness of psychological interventions for reducing depressive symptomatology and overload and improving quality of life in informal caregivers of non-institutionalized dependent elderly: a systematic review.

Introduction: The phenomenon of aging is distinguished by profound life transformations, with the most dependent group being constituted by elderly individuals. The responsibility for their care primarily falls on the figure of the informal caregiver. The scarcity of time, the stress associated with caregiving, the financial, work-related, and personal difficulties it entails, make it a collective with high probabilities of experiencing various psychological disorders. Interventions that have shown the best results are those of multiple components, composed of various techniques that seek to adapt to the reality of the informal caregiver. Method: The purpose of this study is a systematic review of effective interventions on depressive symptoms, emotional wellbeing, burden, or quality of life in informal caregivers of non-institutionalized dependents from 2018 to the present. A search was conducted in November 2023, on Pubmed, Pubmed Central, Proquest, and Scielo. The final review was conducted on 11 articles. Results: The results indicate that multiple component interventions including cognitive behavioral techniques and psychoeducation in combination with stress coping techniques and social support are more effective on depressive symptoms, burden, quality of life, and increasing the social support network. Discussion: Results on web-based programs demonstrate their efficacy and effectiveness, but require a greater number of trials to adjust their methodological quality and content to the idiosyncrasies of the informal caregiver.

Teen dating violence: predictive role of sexism and the mediating role of empathy and assertiveness based on gender.

Background: Despite efforts to prevent dating violence among adolescents, it remains a major problem with multiple negative consequences. Sexist beliefs, empathy, and assertiveness influence teen dating violence (TDV) with potential gender differences. Objectives: (1) Determine gender disparities in TDV perpetration and victimization, including relational, verbal-emotional, and physical aspects, as well as roles; (2) Analyze gender variations in sexism, empathy, assertiveness, and their relationship with TDV; (3) Establish a predictive model of sexism in TDV with empathy and assertiveness as mediators for both genders. Participants and setting: A sample of 862 secondary school students (50.2% females, 49.8% males; mean age: 14.1 years) from diverse regions in Spain participated. Methods: TDV was measured using the Conflict in Adolescent Dating Relationships Inventory (CADRI) in a cross-sectional study. Sexism, empathy, and assertiveness were assessed using the Ambivalent Sexism Inventory (ASI), Interpersonal Reactivity Index (IRI), and Assertiveness Inventory for Students Questionnaire (AISQ), respectively. Results: Females exhibited higher TDV perpetration, specifically verbal-emotional TDV. Males showed more relational TDV and hostile sexism, while no benevolent sexism differences were observed. Mediation models demonstrated sexism, assertiveness, and empathy as individual predictors of TDV, with varying mediation effects. Personal distress partially mediates the link between sexism and TDV perpetration or victimization in males, while practical personal ability mediates between sexism and TDV perpetration in females. Conclusion: Sexism predicts both perpetration and victimization in TDV, linked to empathy and assertiveness. Notably, specific dimensions of empathy and assertiveness mediate the connection between sexism and TDV, displaying gender-specific patterns. Preventive measures should consider personal distress in male perpetrators/victims and practical personal ability in female perpetrators.

Necrotizing fasciitis of the thigh secondary to perforated rectal cancer: the sciatic foramen as a route for infective spread.

Necrotizing fasciitis (NF) is a potentially life-threatening surgical emergency. It is a rapidly progressive infection of soft tissues, and mortality is related to the degree of sepsis and the general condition of the patient. It is a rare condition that requires a rapid diagnosis and surgical treatment is aggressive debridement. There are a small number of reported cases of perforation of a rectal malignancy leading to NF of the thigh. We present a case with rectal cancer in which the sciatic foramen had provided a channel for the spread of pelvic infection into the thigh.

La fascitis necrotizante es una emergencia quirúrgica potencialmente mortal. Es una infección de tejidos blandos rápidamente progresiva y la mortalidad está relacionada con el grado de sepsis y el estado general del paciente. Es una condición poco común que requiere un diagnóstico rápido, y el tratamiento quirúrgico consiste en un desbridamiento agresivo. Existe un pequeño número de casos notificados de perforación de neoplasia maligna de recto que conduce a fascitis necrotizante del muslo. Presentamos un caso de cáncer de recto en el cual el foramen ciático fue el canal para la propagación de la infección pélvica al muslo.

Outcomes and predictors of left ventricle recovery in patients with severe left ventricular dysfunction undergoing transcatheter aortic valve implantation.

BACKGROUND: Data on the likelihood of left ventricle (LV) recovery in patients with severe LV dysfunction and severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and its prognostic value are limited. AIMS: We aimed to assess the likelihood of LV recovery following TAVI, examine its association with midterm mortality, and identify independent predictors of LV function. METHODS: In our multicentre registry of 17 TAVI centres in Western Europe and Israel, patients were stratified by baseline LV function (ejection fraction [EF] >/≤30%) and LV response: no LV recovery, LV recovery (EF increase ≥10%), and LV normalisation (EF ≥50% post-TAVI). RESULTS: Our analysis included 10,872 patients; baseline EF was ≤30% in 914 (8.4%) patients and >30% in 9,958 (91.6%) patients. The LV recovered in 544 (59.5%) patients, including 244 (26.7%) patients whose LV function normalised completely (EF >50%). Three-year mortality for patients without severe LV dysfunction at baseline was 29.4%. Compared to this, no LV recovery was associated with a significant increase in mortality (adjusted hazard ratio 1.32; p<0.001). Patients with similar LV function post-TAVI had similar rates of 3-year mortality, regardless of their baseline LV function. Three variables were associated with a higher likelihood of LV recovery following TAVI: no previous myocardial infarction (MI), estimated glomerular filtration rate >60 mL/min, and mean aortic valve gradient (mAVG) (expressed either as a continuous variable or as a binary variable using the standard low-flow, low-gradient aortic stenosis [AS] definition). CONCLUSIONS: LV recovery following TAVI and the extent of this recovery are major determinants of midterm mortality in patients with severe AS and severe LV dysfunction undergoing TAVI. Patients with no previous MI and those with an mAVG >40 mmHg show the best results following TAVI, which are at least equivalent to those for patients without severe LV dysfunction.

A Core Outcome Set for Efficacy of Acute Treatment of Hereditary Angioedema.

BACKGROUND: Clinical trials investigating drugs for the acute treatment of hereditary angioedema attacks have assessed many different outcomes. This heterogeneity limits the comparability of trial results and may lead to selective outcome reporting bias and a high burden on trial participants. OBJECTIVE: To achieve consensus on a core outcome set composed of key outcomes that ideally should be used in all clinical efficacy trials involving the acute treatment of hereditary angioedema attacks. METHODS: We conducted a Delphi consensus study involving all relevant parties: patients with hereditary angioedema, hereditary angioedema expert clinicians and clinical researchers, pharmaceutical companies, and regulatory bodies. Two Internet-based survey rounds were conducted. In round 1, panelists indicated the importance of individual outcomes used in clinical trials on a 9-point Likert scale. Based on these results, a core outcome set was developed and voted on by panelists in round 2. RESULTS: A total of 58 worldwide panelists completed both rounds. The first round demonstrated high importance scores and substantial agreement among the panelists. In the second round, a consensus of 90% or greater was achieved on a core outcome set consisting of five key outcomes: change in overall symptom severity at one predetermined time point between 15 minutes and 4 hours after treatment, time to end of progression of all symptoms, the need for rescue medication during the entire attack, impairment of daily activities, and treatment satisfaction. CONCLUSIONS: This international study obtained a high level of consensus on a core outcome set for the acute treatment of hereditary angioedema attacks, consisting of five key outcomes.

New Genetic Variants of RUNX2 in Mexican Families Cause Cleidocranial Dysplasia.

Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia characterized by persistent open skull sutures with bulging calvaria, hypoplasia, or aplasia of clavicles permitting abnormal opposition of the shoulders; wide public symphysis; short middle phalanx of the fifth fingers; and vertebral, craniofacial, and dental anomalies. It is a rare disease, with a prevalence of 1-9/1,000,000, high penetrance, and variable expression. The gene responsible for CCD is the Runt-related transcription factor 2 (RUNX2) gene. We characterize the clinical, genetic, and bioinformatic results of four CCD cases: two cases within Mexican families with six affected members, nine asymptomatic individuals, and two sporadic cases with CCD, with one hundred healthy controls. Genomic DNA analyses of the RUNX2 gene were performed for Sanger sequencing. Bioinformatics tools were used to predict the function, stability, and structural changes of the mutated RUNX2 proteins. Three novel heterozygous mutations (c.651_652delTA; c.538_539delinsCA; c.662T>A) and a previously reported mutation (c.674G>A) were detected. In silico analysis showed that all mutations had functional, stability-related, and structural alterations in the RUNX2 protein. Our results show novel mutations that enrich the pool of RUNX2 gene mutations with CCD. Moreover, the proband 1 presented clinical data not previously reported that could represent an expanded phenotype of severe expression.

Association between prenatal and childhood PM2.5 exposure and preadolescent anxiety and depressive symptoms.

Background: Fine particulate matter (PM2.5) exposure has been linked to anxiety and depression in adults; however, there is limited research in the younger populations, in which symptoms often first arise. Methods: We examined the association between early-life PM2.5 exposure and symptoms of anxiety and depression in a cohort of 8-11-year-olds in Mexico City. Anxiety and depressive symptoms were assessed using the Spanish versions of the Revised Children's Manifest Anxiety Scale and Children's Depression Inventory. Daily PM2.5 was estimated using a satellite-based exposure model and averaged over several early and recent exposure windows. Linear and logistic regression models were used to estimate the change in symptoms with each 5-µg/m3 increase in PM2.5. Models were adjusted for child's age, child's sex, maternal age, maternal socioeconomic status, season of conception, and temperature. Results: Average anxiety and depressive symptom T-scores were 51.0 (range 33-73) and 53.4 (range 44-90), respectively. We observed consistent findings for exposures around the fourth year of life, as this was present for both continuous and dichotomized anxiety symptoms, in both independent exposure models and distributed lag modeling approaches. This window was also observed for elevated depressive symptoms. An additional consistent finding was for PM2.5 exposure during early pregnancy in relation to both clinically elevated anxiety and depressive symptoms, this was seen in both traditional and distributed lag modeling approaches. Conclusion: Both early life and recent PM2.5 exposure were associated with higher mental health symptoms in the child highlighting the role of PM2.5 in the etiology of these conditions.

PSF-Radon transform algorithm: Measurement of the point-spread function from the Radon transform of the line-spread function.

In this article, we present a new method called point spread function (PSF)-Radon transform algorithm. This algorithm consists on recovering the instrument PSF from the Radon transform (in the line direction axis) of the line spread function (i.e., the image of a line). We present the method and tested with synthetic images, and real images from macro lens camera and microscopy. A stand-alone program along with a tutorial is available, for any interested user, in Martinez (PSF-Radon transform algorithm, standalone program). RESEARCH HIGHLIGHTS: Determining the instrument PSF is a key issue. Precise PSF determinations are mandatory if image improvement is performed numerically by deconvolution. Much less exposure time to achieve the same performance than a measurement of the PSF from a very small bead. Does not require having to adjust the PSF by an analytical function to overcome the noise uncertainties.

Disturbances in the IgG Antibody Profile in HIV-Exposed Uninfected Infants Associated with Maternal Factors.

Over the last 20 years, the incidence of vertical HIV transmission has decreased from 25%-42% to less than 1%. Although there are no signs of infection, the health of HIV-exposed uninfected (HEU) infants is notoriously affected during the first months of life, with opportunistic infections being the most common disease. Some studies have reported effects on the vertical transfer of antibodies, but little is known about the subclass distribution of these antibodies. We proposed to evaluate the total IgG concentration and its subclasses in HIV+ mothers and HEU pairs and to determine which maternal factors condition their levels. In this study, plasma from 69 HEU newborns, their mothers, and 71 control pairs was quantified via immunoassays for each IgG isotype. Furthermore, we followed the antibody profile of HEUs throughout the first year of life. We showed that mothers present an antibody profile characterized by high concentrations of IgG1 and IgG3 but reduced IgG2, and HEU infants are born with an IgG subclass profile similar to that of their maternal pair. Interestingly, this passively transferred profile could remain influenced even during their own antibody production in HEU infants, depending on maternal conditions such as CD4+ T-cell counts and maternal antiretroviral treatment. Our findings indicate that HEU infants exhibit an altered IgG subclass profile influenced by maternal factors, potentially contributing to their increased susceptibility to infections.

Attitudes toward death and burnout syndrome in geriatrics and gerontology healthcare personnel / Actitudes hacia la muerte y síndrome de burnout en el personal sanitario de geriatría y gerontología

Introduction Geriatric and gerontology healthcare workers are associated with a series of psychosocial risks such as death, bereavement and illness, and this implies a significant emotional and work overload, which can lead to negative attitudes toward death. Objective The aims of this study were to assess attitudes toward death, the level of burnout and the relationship between geriatrics and gerontology professionals. Method A correlational, cross-sectional study was conducted, in which the 42 participants in the sample completed an online questionnaire including the Revised Profile of Attitudes to Death (PAM-R) and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Results The results obtained show that the predominant attitude toward death in the sample is that of neutral acceptance, and with regard to burnout syndrome, moderate average levels are found in the dimensions of emotional exhaustion and personal accomplishment, but a low level of depersonalisation. Conclusion Healthcare workers with attitudes of greater fear of death or acceptance of escape tend to experience higher levels of emotional exhaustion and depersonalisation, as do those with an attitude of death avoidance, who also have lower personal fulfillment (AU)

Calidad de vida en adolescentes. Un estudio longitudinal del impacto de la pandemia por COVID-19 / Quality of life in adolescents. A longitudinal study of the impact of the COVID-19 pandemic

Diversos estudios han informado que la calidad de vida relacionada con la salud (CVRS) en adolescentes ha disminuido durante la pandemia por COVID-19. En este trabajo se analizó la CVRS en jóvenes de 13 a 17 años una vez finalizada la pandemia. Para ello se hizo un seguimiento en tres momentos diferentes: antes de la pandemia (2019), durante las restricciones de la pandemia (2021) y tras las restricciones de la misma (2022). Se utilizó un diseño de retardo temporal (time-lag design) en tres fases, con un total de 2027 adolescentes que cumplimentaron el cuestionario Kidscreen-10 de CVRS. Mediante modelos ANOVA y de regresión logística se analizó la influencia del género, la práctica deportiva y estar en tratamiento en salud mental. Los resultados obtenidos mostraron un empeoramiento de la CVRS en 2021, cuando los jóvenes volvían a los centros educativos en régimen de semipresencialidad. Este descenso fue independiente del género. En 2022, una vez eliminadas todas las restricciones, la CVRS se recuperó a niveles prepandemia en los chicos, pero no en las chicas. Lo mismo ocurrió con los jóvenes en tratamiento de salud mental. En todos los casos, la práctica deportiva se mostró como un factor protector de la CVRS.(AU)

Several studies have reported that health-related quality of life (HRQoL) in adolescents has decreased during the COVID-19 pandemic. In this study, HRQoL was analyzed in young people aged 13 to 17 years after the end of the pandemic. For this purpose, we followed up at three different points in time: before the pandemic (2019), during (2021) and af-ter the pandemic restrictions (2022).A time-lag design in three phases was used, with a total of 2027 adolescents completing the Kidscreen-10 HRQoL questionnaire. ANOVA and logistic regression models were used to analyze the influence of gender, playing sports and mental health treat-ment.The results obtained showed a worsening of HRQoL in 2021, when young people returned to school on a blended learning basis.This worsen-ing occurred regardless of gender. In 2022, once all restrictions were re-moved, boys recovered health-related quality of life to pre-pandemic levels, but this did not occur in girls. The same happened with young people in mental health treatment. In all cases, doing sports was shown to be a pro-tective factor for HRQoL.(AU)

Subclinical Left Ventricular Systolic Dysfunction in Hospitalized Patients with COVID-19 by Strain: A 30-Day Echocardiographic Follow-Up.

Background and Objectives: Available studies confirm myocardial injury and its association with mortality in patients with COVID-19, but few data have been reported from echocardiographic studies. The aim of this study was to identify subclinical left ventricular dysfunction by global longitudinal strain (GLS) and its evolution in the short term in hospitalized patients with COVID-19. Materials and Methods: Thirty-one consecutive noncritical patients admitted for COVID-19 were included. Information on demographics, laboratory results, comorbidities, and medications was collected. Transthoracic echocardiograms were performed using a Philips Affinity 50, at the acute stage and at a 30-day follow-up. Automated left ventricular GLS was measured using a Philips Qlab 13.0. A GLS of <-15.9% was defined as abnormal. Results: The mean age was 65 ± 15.2 years, and 61.3% of patients were male. Nine patients (29%) had elevated levels of high-sensitivity troponin I. Left ventricular ejection fraction was preserved in all; however, 11 of them (35.5%) showed reduced GLS. These patients had higher troponin levels (median, 23.7 vs. 3.2 ng/L; p < 0.05) and NT-proBNP (median, 753 vs. 81 pg/mL; p < 0.05). The multivariate analysis revealed that myocardial injury, defined as increased troponin, was significantly associated with GLS values (coefficient B; p < 0.05). Follow-up at 30 days showed an improvement in GLS values in patients with subclinical left ventricular dysfunction (-16.4 ± 2.07% vs. -13.2 ± 2.40%; p < 0.01), without changes in the normal GLS group. Conclusions: Subclinical left ventricular dysfunction is common in noncritical hospitalized patients with COVID-19 (one in every three patients), even with preserved left ventricular ejection fraction. This impairment tends to be reversible on clinical recovery.
