Crisis resolution teams (CRTs) are a crucial component of mental health care, providing timely support to individuals experiencing acute mental health crises. This abstract delves into the concept of crisis and seeks to identify the patients who stand to benefit from these specialized services.

Defining crisis within the context of CRTs can be complex. It encompasses not only immediate emergencies but also broader mental health distress.

Research suggests that suitable candidates for CRT interventions are those facing acute mental health crises : This includes individuals experiencing suicidal ideation, severe agitation, or severe emotional distress.

La “Escala de Evaluación de Resolución de Crisis” (Crisis Resolution Team Assessment Tool, CRTAT) de Sonia Johnson es una herramienta diseñada para para medir la efectividad de los CRT y la duración de la intervención en crisis. Establece un límite de seis semanas como el período máximo durante el cual se debe ofrecer la atención en crisis.

Existen otras escalas de evaluación para medir la eficacia de la resolución de crisis:

1. 1. Escala de Intensidad de Crisis (CIS): se utiliza para medir la gravedad de la crisis y la necesidad de intervención inmediata.

2. 2. Escala de Evaluación de Crisis de Brage Hansen (BCES): se enfoca en la evaluación de crisis suicidas y evalúa la intensidad de la ideación suicida y la urgencia de la intervención.

3. 3. Escala de Evaluación de Crisis de Eriksson (ECAS): Diseñada para evaluar la intensidad de la crisis en pacientes psiquiátricos, la ECAS se centra en la agitación, la ansiedad y la angustia emocional.

- Studies have explored the effectiveness of CRTs and the perspectives of service users. Understanding how patients perceive crisis and CRT services is crucial for tailoring interventions effectively.

- CRTs play a vital role in mental health care, offering timely support to individuals experiencing crises. While defining crisis is complex, suitable candidates often include those in acute distress requiring immediate intervention. Understanding the perspectives of service users and the diverse nature of crisis experiences informs effective crisis resolution strategies.

“Cluster suicides,” also known as “suicide clusters,” refer to a phenomenon in which a series of suicides occur within a specific community, group, or geographic area within a relatively short period of time. These suicides often appear to be interconnected, either through imitation or contagion, and may involve individuals who have some form of social or emotional connection to each other.

• - Understanding the definition and characteristics of cluster suicides.

• - Analyzing common risk factors and triggers in cluster suicide cases.

• - Evaluating prevention and support strategies for affected individuals and communities.

We conduct an analysis of this concept based on a sample of suicides that occurred in a Spanish region over an 8-year period (2015-2022).

High cognitive activity possibly reduces the risk of cognitive decline and dementia.

To investigate associations between an individual's need to engage in cognitively stimulating activities (need for cognition, NFC) and structural brain damage and cognitive functioning in the Dutch general population with and without existing cognitive impairment.

Cross-sectional data were used from the population-based cohort of the Maastricht Study. NFC was measured using the Need For Cognition Scale. Cognitive functioning was tested in three domains: verbal memory, information processing speed, and executive functioning and attention. Values 1.5 s.d. below the mean were defined as cognitive impairment. Standardised volumes of white matter hyperintensities (WMH), cerebrospinal fluid (CSF) and presence of cerebral small vessel disease (CSVD) were derived from 3T magnetic resonance imaging. Multiple linear and binary logistic regression analyses were used adjusted for demographic, somatic and lifestyle factors.

Participants (n = 4209; mean age 59.06 years, s.d. = 8.58; 50.1% women) with higher NFC scores had higher overall cognition scores (B = 0.21, 95% CI 0.17–0.26, P < 0.001) and lower odds for CSVD (OR = 0.74, 95% CI 0.60–0.91, P = 0.005) and cognitive impairment (OR = 0.60, 95% CI 0.48–0.76, P < 0.001) after adjustment for demographic, somatic and lifestyle factors. The association between NFC score and cognitive functioning was similar for individuals with and without prevalent cognitive impairment. We found no significant association between NFC and WMH or CSF volumes.

A high need to engage in cognitively stimulating activities is associated with better cognitive functioning and less presence of CSVD and cognitive impairment. This suggests that, in middle-aged individuals, motivation to engage in cognitively stimulating activities may be an opportunity to improve brain health.

Late-life depression has been associated with volume changes of the hippocampus. However, little is known about its association with specific hippocampal subfields over time.

We investigated whether hippocampal subfield volumes were associated with prevalence, course and incidence of depressive symptoms.

We extracted 12 hippocampal subfield volumes per hemisphere with FreeSurfer v6.0 using T1-weighted and fluid-attenuated inversion recovery 3T magnetic resonance images. Depressive symptoms were assessed at baseline and annually over 7 years of follow-up (9-item Patient Health Questionnaire). We used negative binominal, logistic, and Cox regression analyses, corrected for multiple comparisons, and adjusted for demographic, cardiovascular and lifestyle factors.

A total of n = 4174 participants were included (mean age 60.0 years, s.d. = 8.6, 51.8% female). Larger right hippocampal fissure volume was associated with prevalent depressive symptoms (odds ratio (OR) = 1.26, 95% CI 1.08–1.48). Larger bilateral hippocampal fissure (OR = 1.37–1.40, 95% CI 1.14–1.71), larger right molecular layer (OR = 1.51, 95% CI 1.14–2.00) and smaller right cornu ammonis (CA)3 volumes (OR = 0.61, 95% CI 0.48–0.79) were associated with prevalent depressive symptoms with a chronic course. No associations of hippocampal subfield volumes with incident depressive symptoms were found. Yet, lower left hippocampal amygdala transition area (HATA) volume was associated with incident depressive symptoms with chronic course (hazard ratio = 0.70, 95% CI 0.55–0.89).

Differences in hippocampal fissure, molecular layer and CA volumes might co-occur or follow the onset of depressive symptoms, in particular with a chronic course. Smaller HATA was associated with an increased risk of incident (chronic) depression. Our results could capture a biological foundation for the development of chronic depressive symptoms, and stresses the need to discriminate subtypes of depression to unravel its biological underpinnings.

Although some studies have reported that case management (CM), when is compared with standard care, reduces the loss of contact with health services, the debate continues about its superiority over other treatment models.

To assess treatment adherence and reasons for treatment discontinuation, and the impact of the type of APs administration on it, for a group of patients with schizophrenia treated in a CMP or receiving standard treatment in mental health units (MHUs).

An observational, longitudinal study (ten-year follow-up) was conducted on 688 patients with severe schizophrenia (CGI-S ≥ 5). All the causes of the end of treatment were recorded, together with the AP medication prescribed and kind of regimes.

43.6% of the patients had discontinued treatment in MHUs and only 12.1% on the CMP (p < 0.0001). 27.6% of patients in MHUs were on long-acting injectables (LAIs), and 57.6 on the CMP (p < 0.001). Treatment discontinuation was closely linked to be on OAPs medication in both cases (p < 0.001).Table 1.Treatment discontinuation, hospital admissions and suicide attempts [N(%)]

Our findings show how specific strategies as programs with an integrated treatment and case-managed approach, increase adherence. Moreover, treating with LAI APs clearly contributes to the achievement of these results. The widespread implementation of comprehensive community programs with case management, and the use of LAI-APs, should be an effective choice for people with schizophrenia and clinical severity and impairment, and at high risk of treatment discontinuation.

To determine risk factors for the development of long coronavirus disease 2019 (COVID-19) in healthcare personnel (HCP).

We conducted a case–control study among HCP who had confirmed symptomatic COVID-19 working in a Brazilian healthcare system between March 1, 2020, and July 15, 2022. Cases were defined as those having long COVID according to the Centers for Disease Control and Prevention definition. Controls were defined as HCP who had documented COVID-19 but did not develop long COVID. Multiple logistic regression was used to assess the association between exposure variables and long COVID during 180 days of follow-up.

Of 7,051 HCP diagnosed with COVID-19, 1,933 (27.4%) who developed long COVID were compared to 5,118 (72.6%) who did not. The majority of those with long COVID (51.8%) had 3 or more symptoms. Factors associated with the development of long COVID were female sex (OR, 1.21; 95% CI, 1.05–1.39), age (OR, 1.01; 95% CI, 1.00–1.02), and 2 or more SARS-CoV-2 infections (OR, 1.27; 95% CI, 1.07–1.50). Those infected with the SARS-CoV-2 δ (delta) variant (OR, 0.30; 95% CI, 0.17–0.50) or the SARS-CoV-2 o (omicron) variant (OR, 0.49; 95% CI, 0.30–0.78), and those receiving 4 COVID-19 vaccine doses prior to infection (OR, 0.05; 95% CI, 0.01–0.19) were significantly less likely to develop long COVID.

Long COVID can be prevalent among HCP. Acquiring >1 SARS-CoV-2 infection was a major risk factor for long COVID, while maintenance of immunity via vaccination was highly protective.

Individuals with depression have an increased dementia risk, which might be due to modifiable risk factors for dementia. This study investigated the extent to which the increased risk for dementia in depression is explained by modifiable dementia risk factors.

We used data from the English Longitudinal Study of Ageing (2008–2009 to 2018–2019), a prospective cohort study. A total of 7460 individuals were included [mean(standard deviation) age, 65.7 ± 9.4 years; 3915(54.7%) were women]. Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale-8 (score ≥3) or self-reported doctor's diagnosis. Ten modifiable risk factors for dementia were combined in the ‘LIfestyle for BRAin health’ (LIBRA) score. Dementia was determined by physician diagnosis, self-reported Alzheimer's disease or the shortened version of the Informant Questionnaire on Cognitive Decline in the Elderly (average score ≥3.38). Structural equation modelling was used to test mediation of LIBRA score.

During 61 311 person-years, 306 individuals (4.1%) developed dementia. Participants aged 50–70 years with depressive symptoms had higher LIBRA scores [difference(s.e.) = 1.15(0.10)] and a 3.59 times increased dementia risk [HR(95% CI) = 3.59(2.20–5.84)], adjusted for age, sex, education, wealth and clustering at the household level. In total, 10.4% of the dementia risk was mediated by differences in LIBRA score [indirect effect: HR = 1.14(1.03–1.26)], while 89.6% was attributed to a direct effect of depressive symptoms on dementia risk [direct effect: HR = 3.14(2.20–5.84)].

Modifiable dementia risk factors can be important targets for the prevention of dementia in individuals with depressive symptoms during midlife. Yet, effect sizes are small and other aetiological pathways likely exist.
