Acceptance and commitment therapy (ACT), as an empirically based third-wave cognitive behavioral therapy, has shown promise in enhancing well-being and functioning across diverse populations. ...However, in the context of caregiving, the effect size of available ACT interventions remains at best moderate, sometimes accompanied by high dropout rates, highlighting the need for more effective and feasible intervention designs.
The objective of our study was to evaluate the feasibility and acceptability of a fully online ACT program designed for family caregivers of people with dementia. This study aimed to boost psychological flexibility and support caregivers, enabling them to realize and prioritize their own life values alongside their caregiving responsibilities.
A mixed methods feasibility study using an uncontrolled pretest-posttest design was conducted. This intervention included a 9-week web-based self-help program based on ACT incorporating collaborative goal setting and weekly web-based motivational coaching for family caregivers of people with dementia. This study involved 30 informal caregivers recruited through memory clinics and social media platforms in the Netherlands and received approval from the Medical Ethics Committee of the Maastricht University Medical Center+ (NL77389.068.21/metc21-029).
A total of 24 caregivers completed the postintervention assessment, indicating a high adherence rate (24/29, 83%). Caregivers reported positive feedback regarding collaborative goal setting, but some found challenges in implementing new skills due to their own habitual responses or the unpredictable context of dementia caregiving. Personalizing the intervention based on individual value preferences was highlighted as beneficial.
Compared to other web-based self-help ACT interventions for family caregivers, this intervention showed a high adherence and sufficient level of feasibility, which underscores the use of personalization in delivering web-based interventions. Moreover, the potential of this ACT-based intervention for family caregivers of people with dementia was demonstrated, suggesting that further research and a larger-scale controlled trial are warranted to validate its effectiveness.

The distribution and regulation of the cohesin complexes have been extensively studied during mitosis. However, the dynamics of their different regulators in vertebrate meiosis is largely unknown. In ...this work, we have analyzed the distribution of the regulatory factor Sororin during male mouse meiosis. Sororin is detected at the central region of the synaptonemal complex during prophase I, in contrast with the previously reported localization of other cohesin components in the lateral elements. This localization of Sororin depends on the transverse filaments protein SYCP1, but not on meiosis‐specific cohesin subunits REC8 and SMC1β. By late prophase I, Sororin accumulates at centromeres and remains there up to anaphase II. The phosphatase activity of PP2A seems to be required for this accumulation. We hypothesize that Sororin function at the central region of the synaptonemal complex could be independent on meiotic cohesin complexes. In addition, we suggest that Sororin participates in the regulation of centromeric cohesion during meiosis in collaboration with SGO2‐PP2A.
Synopsis
This study analyses the distribution of Sororin, a regulatory factor of the cohesin complex, during male mouse meiosis. The results suggest different functions of Sororin at the synaptonemal complex and at the centromere.
Sororin loads to the central region of the synaptonemal complex in a SYCP1‐dependent manner, but independently of cohesin complexes containing meiosis‐specific REC8 and SMC1β subunits.
Sororin accumulates at the centromere by late prophase I and remains there until anaphase II.
Sororin could participate in the regulation of centromeric cohesion during meiosis in collaboration with the SGO2‐PP2A complex.

Armed conflict has positioned Colombia as the country with the second highest internal displacement of citizens. This situation has forced government projects and international cooperation agencies ...to intervene to mitigate the impact of violence; however, the coping strategies implemented by the country's minorities are still unknown. The study objective is to describe the coping strategies and their relation with mental health within Afro-descendant culture in Colombia and the effects that armed conflict has on these coping mechanisms, through a phenomenological study involving focus groups and interviews with experts. Rituals and orality have a healing function that allow Afro-Colombian communities to express their pain and support each other, enabling them to cope with loss. Since the forced displacement, these traditions have been in jeopardy. Armed conflict prevents groups from mourning, generating a form of latent pain. Afro-Colombians require community interventions that create similar spaces for emotional support for the bereaved persons in the pre-conflict period. Thus, it is essential to understand the impact of this spiritual and ritualistic approach on mental health issues and the relevance of narrative and community interventions for survivors.
Increased systemic levels of inflammatory cytokines have been associated with the development of pathophysiologic events during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. ...To further explore differences in the pattern and dynamics of plasma cytokines in individuals with coronavirus disease-19 (COVID-19), and the relationship with disease mortality, here we evaluated the plasma levels of proinflammatory and regulatory cytokines in Colombian patient survivors and nonsurvivors of SARS-CoV-2 infection. Individuals with confirmed COVID-19, with other respiratory diseases requiring hospitalization, and healthy controls, were included. Plasma levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, interferon-γ, IL-10, soluble tumor necrosis factor receptor I (sTNFRI), and transforming growth factor-β1 were measured by a bead-based assay or enzyme-linked immunosorbent assay and clinical, laboratory, and tomographic parameters were registered during hospitalization. The levels of most of the evaluated cytokines were increased in COVID-19 individuals relative to healthy controls. The levels of IL-6, IL-10, and sTNFRI were directly associated with the development of respiratory failure, immune dysregulation, and coagulopathy, as well as with COVID-19 mortality. Particularly, the early, robust, and persistent increase of circulating IL-6 characterized COVID-19 nonsurvivors, while survivors were able to counteract the inflammatory cytokine response. In addition, IL-6 systemic levels positively correlated with the tomographic extension of lung damage in individuals with COVID-19. Thus, an exacerbated inflammatory cytokine response, particularly mediated by IL-6 added to the inefficiency of regulatory cytokines, distinguishes COVID-19-associated tissue disturbances, severity, and mortality in Colombian adults.
Hepatobiliary, pancreatic, and gastrointestinal cancers account for 36% of the ten million deaths caused by cancer worldwide every year. The two main reasons for this high mortality are their late ...diagnosis and their high refractoriness to pharmacological treatments, regardless of whether these are based on classical chemotherapeutic agents, targeted drugs, or newer immunomodulators. Mechanisms of chemoresistance (MOC) defining the multidrug resistance (MDR) phenotype of each tumor depend on the synergic function of proteins encoded by more than one hundred genes classified into seven groups (MOC1-7). Among them, the efflux of active agents from cancer cells across the plasma membrane caused by members of the superfamily of ATP-binding cassette (ABC) proteins (MOC-1b) plays a crucial role in determining tumor MDR. Although seven families of human ABC proteins are known, only a few pumps (mainly MDR1, MRP1-6, and BCRP) have been associated with reducing drug content and hence inducing chemoresistance in hepatobiliary, pancreatic, and gastrointestinal cancer cells. The present descriptive review, which compiles the updated information on the expression of these ABC proteins, will be helpful because there is still some confusion on the actual relevance of these pumps in response to pharmacological regimens currently used in treating these cancers. Moreover, we aim to define the MOC pattern on a tumor-by-tumor basis, even in a dynamic way, because it can vary during tumor progression and in response to chemotherapy. This information is indispensable for developing novel strategies for sensitization.
Olive pollen is one of the most important causes of respiratory allergy, with Ole e 1 being the most clinically relevant sensitizing allergen. Peptide-based vaccines represent promising therapeutic ...approaches, but the use of adjuvants is required to strengthen the weak immunogenicity of small peptides. We propose the use of dendrimeric scaffolds conjugated to the T cell immunodominant epitope of Ole e 1 (OE109–130) for the development of novel vaccines against olive pollen allergy. Four dendrimeric scaffolds containing an ester/ether with nine mannoses, an ester succinimidyl linker with nine N-acetyl-glucosamine units or nine ethylene glycol units conjugated to OE109–130 peptide were designed, and their cytotoxicity, internalization pattern, and immunomodulatory properties were analyzed in vitro. None of the dendrimers exhibited cytotoxicity in humanized rat basophil (RBL-2H3), human bronchial epithelial Calu-3, and human mast LAD2 cell lines. Confocal images indicated that mannosylated glycodendropeptides exhibited lower colocalization with a lysosomal marker. Moreover, mannosylated glycodendropeptides showed higher transport tendency through the epithelial barrier formed by Calu-3 cells cultured at the air–liquid interface. Finally, mannosylated glycodendropeptides promoted Treg and IL10+Treg proliferation and IL-10 secretion by peripheral blood mononuclear cells from allergic patients. Mannosylated dendrimers conjugated with OE109–130 peptide from Ole e 1 have been identified as suitable candidates for the development of novel vaccines of olive pollen allergy.
Given the context and the number of armed conflict victims in the Colombian Pacific coast and their difficulties to access psycho-social care, Narrative Community-based Group Therapy appears as a ...viable mental health intervention. The objective of this study is to describe the process of implementation and results of the intervention in Afro-Colombian victims of violence, in the municipalities of Buenaventura and Quibdó. More specifically, we will be looking at the perspectives of workers and supervisors, through evaluative case studies and individual in-depth interviews. The therapy allows us to identify support and coping systems through coexistence, communication and interaction. It requires an adaptation process to the diversity of knowledge and expressions of victims of Colombian violence, greater empathy from care providers and rigor in their profiles selection, facilities ensuring security and confidentiality, and links with other educational, employment and recreational organizations. It is important to include these results while improving current and future intervention processes.
Women who are victims of intimate partner violence often suffer of depression and anxiety disorders. We evaluated the performance of the SRQ-20 scale (screening test for common mental health ...disorders), in women victims of intimate partner violence by male partners. A total of 100 women were surveyed from the out-patient mental health services in four health institutions in Valle del Cauca (Colombia). SRQ-20 scales (Binary version versus Likert version) were compared with mental health diagnoses based on the HSCL-25 scale, as the gold standard. Optimal SRQ-20 cut-off score is > = 6 points; lower than the initially suggested, sensitivity of 96.6% and specificity of 90.9%. The new SRQ-20-Likert scale, establishing a cut-off of > = 8 points, shows better sensitivity (98.9%) and equal specificity than the original scale. Studied SRQ-20 scales are promising instruments for screening mental health disorders among women victims of intimate partner violence in primary health care settings.

Due to the limited supply of mental health services for Afro-Colombian victims of violence, a Common Elements Treatment Approach (CETA) intervention has been implemented in the Colombian Pacific. ...Given the importance of improvement in mental health interventions for this population, it is necessary to characterize this process. This article seeks to describe the implementation of CETA for Afro-Colombian victims of violence in Buenaventura and Quibdó, Colombia through case studieswith individual in-depth interviews with Lay Psychosocial Community Workers (LPCW), supervisors, and coordinators responsible for implementing CETA. From this six core categories were obtained: 1. Effect of armed conflict and poverty 2. Trauma severity 3. Perceived changes with CETA 4. Characteristics and LPCW's performance 5. Afro-Colombian culturalapproach and 6. Strategies to promote users' well-being.Colombian Pacific's scenario implies several factors, such as the active armed conflict, economic crisis, and lack of mental health care resources, affecting the implementation process and the intervention effects. This implies the need to establish and strengthen partnerships between institutions in order to administer necessary mental health care for victims of violence in the Colombian Pacific.
This study analyses gender differences in the complexity observed in palliative home care through a multicentre longitudinal observational study of patients with advanced disease treated by ...palliative home care teams in Catalonia (Spain). We used the HexCom model, which includes six dimensions and measures three levels of complexity: high (non-modifiable situation), medium (difficult) and low. Results:
= 1677 people, 44% women. In contrast with men, in women, cancer was less prevalent (64.4% vs. 73.9%) (
< 0.001), cognitive impairment was more prevalent (34.1% vs. 26.6%;
= 0.001) and professional caregivers were much more common (40.3% vs. 24.3%;
< 0.001). Women over 80 showed less complexity in the following subareas: symptom management (41.7% vs. 51,1%;
= 0.011), emotional distress (24.5% vs. 32.8%;
= 0.015), spiritual distress (16.4% vs. 26.4%;
= 0.001), socio-familial distress (62.7% vs. 70.1%;
= 0.036) and location of death (36.0% vs. 49.6%;
< 0.000). Men were more complex in the subareas of "practice" OR = 1.544 (1.25-1.90
= 0.000) and "transcendence" OR = 1.52 (1.16-1.98
= 0.002). Observed complexity is related to male gender in people over 80 years of age. Women over the age of 80 are remarkably different from their male counterparts, showing less complexity regarding care for their physical, psycho-emotional, spiritual and socio-familial needs.
