The macro-social and environmental conditions in which people live, such as the level of a country’s development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.

We conducted a cross-sectional study pooling brain imaging (T1-based) data from 145 magnetic resonance imaging (MRI) studies in 7,962 healthy adults (4,110 women) in 29 different countries. We used a meta-regression approach to relate the brain structure to the country’s level of development and inequality.

Higher human development was consistently associated with larger hippocampi and more expanded global cortical surface area, particularly in frontal areas. Increased inequality was most consistently associated with smaller hippocampal volume and thinner cortical thickness across the brain.

Our results suggest that the macro-economic conditions of a country are reflected in its inhabitants’ brains and may explain the different incidence of brain disorders across the world. The observed variability of brain structure in health across countries should be considered when developing tools in the field of personalized or precision medicine that are intended to be used across the world.

To simulate the impact of a price subsidy (price reduction) on purchases of healthy foods with suboptimal consumption.

We used data from the 2018 Mexican National Household Income and Expenditure Survey, a cross-sectional study. We estimated own- and cross-price elasticities of the demand for food groups using a Linear Approximation of an Almost Ideal Demand System. Using the estimated elasticities, we derived changes in purchases associated with a 10, 20 and 30 % price reduction in healthy food groups with suboptimal consumption. We also estimated price reductions for these food groups that would meet the recommendations of the Healthy Reference Diet (EAT-HRD) proposed by the EAT-Lancet commission.

Price reductions were associated with increases in the quantity purchased, ranging from 9·4 to 28·3 % for vegetables, 7·9 to 23·8 % for fruits, 0·8 to 2·5 % for legumes and 6·0 to 18·0 % for fish. Higher reductions in prices would be needed to achieve the EAT-Lancet Commission’s recommendations for food groups with suboptimal consumption in Mexico: a 39·7 % reduction in prices for fruits, 20·0 % for vegetables and 118·7 % for legumes.

Our study shows that reductions in prices can lead to increases in purchases of healthier food options. More research is needed to assess the most cost-effective strategy to deliver subsidies using either conditional cash transfers, vouchers or food baskets provided to families or direct subsidies to producers.

Both childhood adversity (CA) and first-episode psychosis (FEP) have been linked to alterations in cortical thickness (CT). The interactive effects between different types of CAs and FEP on CT remain understudied.

One-hundred sixteen individuals with FEP (mean age = 23.8 ± 6.9 years, 34% females, 80.2% non-affective FEP) and 98 healthy controls (HCs) (mean age = 24.4 ± 6.2 years, 43% females) reported the presence/absence of CA <17 years using an adapted version of the Childhood Experience of Care and Abuse (CECA.Q) and the Retrospective Bullying Questionnaire (RBQ) and underwent magnetic resonance imaging (MRI) scans. Correlation analyses were used to assess associations between brain maps of CA and FEP effects. General linear models (GLMs) were performed to assess the interaction effects of CA and FEP on CT.

Eighty-three individuals with FEP and 83 HCs reported exposure to at least one CA. CT alterations in FEP were similar to those found in participants exposed to separation from parents, bullying, parental discord, household poverty, and sexual abuse (r = 0.50 to 0.25). Exposure to neglect (β = −0.24, 95% CI [−0.37 to −0.12], p = 0.016) and overall maltreatment (β = −0.13, 95% CI [−0.20 to −0.06], p = 0.043) were associated with cortical thinning in the right medial orbitofrontal region.

Cortical alterations in individuals with FEP are similar to those observed in the context of socio-environmental adversity. Neglect and maltreatment may contribute to CT reductions in FEP. Our findings provide new insights into the specific neurobiological effects of CA in early psychosis.

This study aims to outline Clostridioides difficile infection (CDI) trends and outcomes in Mexican healthcare facilities during the COVID-19 pandemic.

Observational study of case series.

CDI patients.

Demographic, clinical, and laboratory data of CDI patients were obtained from clinical records. Cases were classified as community or healthcare-associated infections, with incidence rates calculated as cases per 10,000 patient days. Risk factors for 30-day all-cause mortality were analyzed by multivariate logistic regression.

We identified 2,356 CDI cases: 2,118 (90%) were healthcare-associated, and 232 (10%) were community-associated. Common comorbidities included hypertension, diabetes, and cancer. Previous high use of proton-pump inhibitors, steroids, and antibiotics was observed. Recurrent infection occurred in 112 (5%) patients, and 30-day mortality in 371 (16%). Risk factors associated with death were a high Charlson score, prior use of steroids, concomitant use of antibiotics, leukopenia, leukocytosis, elevated serum creatine, hypoalbuminemia, septic shock or abdominal sepsis, and SARS-CoV-2 coinfection. The healthcare-associated CDI incidence remained stable at 4.78 cases per 10,000 patient days during the pre-and pandemic periods. However, the incidence was higher in public hospitals.

Our study underscores the need for routine epidemiology surveillance and standardized CDI classification protocols in Mexican institutions. Though CDI rates in our country align with those in some European countries, disparities between public and private healthcare sectors emphasize the importance of targeted interventions.

Long-term care facilities, such as nursing homes and other assisted living facilities, have been hit particularly hard by the COVID-19. The overall pandemic created an enormous pressure on long-term care workers (LTCWs), making them particularly vulnerable to mental disorders. However, most of the existing evidence regarding the well-being of care professionals has predominantly focused on frontline healthcare workers.

This study aimed to identify long-term psychological needs of LTCWs derived from the COVID-19 pandemic, as part of a project that is developing an intervention to reduce psychological distress in this population group.

We performed a qualitative study with a rapid research approach. Participants were recruited from long-term care facilities located in Catalonia, Spain. Between April and September 2022, we conducted semi-structured interviews inquiring about the most psychologically challenging stages of the pandemic, perceived emotions during those stages, main determinants of those emotions, and their emotional state at the time of the interview. We used a qualitative content analysis method with an inductive-deductive approach.

Thirty LTCWs participated in the study. Mean age was 44 (SD=11,4), 87% were females and one third were from foreign nationalities. The period of the pandemic with highest mental health burden was the outbreak, with almost every worker having experienced some form of emotional distress. Emotional distress persisted over time in more than half of participants, with fatigue and nervousness being the main emotions expressed at the time of the interview. High workload, feeling that pandemic times are not over and poor working conditions that have remained since then, have been the most frequently expressed determinants of such emotions.

Long after the pandemic outbreak, emotional distress is still relevant. The persistent burden of psychological distress points to a need for institutions to take action to improve working conditions and promote employees’ wellbeing.

Suicide attempts (SA) leading to highly lethal consequences have been associated with heightened suicide planning (Barker et al., 2022), along with deficits in social cognition (Levi-Belz et al., 2022). Hypomentalizing, characterized by excessive uncertainty regarding mental states, may contribute to heightened social withdrawal and an increased risk of SA (Nestor & Sutherland, 2022). Although certain studies have identified a connection between hypomentalizing profiles and self-harm (Badoud et al., 2015), research into the lethality of SA remains limited.

This study aimed to explore the association between hypomentalizing and SA lethality.

Our study encompassed a cohort of 1,371 patients who committed a SA. We conducted assessments of mentalizing using the RFQ-8 instrument, and evaluations of suicidal ideation and behavior employing the CSRSS questionnaire. Demographic and clinical characteristics were compared using the T-student and Chi-square tests. To investigate the relationship between hypomentalizing and the SA lethality, we employed logistic regression models.

Descriptive date are presented in Table 1. Our results show that hypomentalizing do not predict a higher SA lethality. Additionally, hypomentalizing increased the risk of SA planning (p≤0.001, B=-0.182), and SA planning predicted a higher SA lethality (see Table 2).Table 1.

Means Comparison for low and high lethality (N=1371)

While the association between hypomentalizing and high SA lethality was not significant, a discernible trend toward such relationship can be noted. Further studies examining the moderating effects of planning in the association between hypomentalizing and SA lethality are required.

Suicide is a serious public health problem. Each year it is estimated that it causes almost one million deaths worldwide, much more than those caused by war or homicide. These deaths are also devastating, affecting not only the person who commits them, but also his or her environment (family, friends, professionals involved, etc.) and society as a whole. The risk and protective factors for suicide are well known in the literature, which gives rise to the estimation of possible high-risk groups according to their characteristics, especially when risk factors are added, protective factors are reduced, and unfavorable life circumstances are present. Among these groups with greater vulnerability to suicidal behavior are homeless people with severe mental disorders, who are unfortunately little visible in society and in the investigation.

The aim of this paper is to review the current state of the question of suicide in homeless people with severe mental disorders.

Review of the international scientific literature on the issue published in the last twenty years.

The few studies available conclude the higher prevalence of suicidal behavior in homeless people with severe mental disorders compared to the general population, which has not been translated into the development of specific care and prevention plans and programs.

It is considered essential to expand investigation in this field, which will be very useful to lay the foundations for the development of guidelines, plans and specific programs, and to know the evidence about them.

Migration has been present in the evolution of human beings throughout history. Economic inequalities give rise to a permanent flow of people trying to improve their lives. In addition, there are people who are forced to seek asylum or refuge due to wars or political violence. Therefore, the migratory flow, gives rise to a clinical scenario in which, the arrival of immigrant people demands an adaptation of the psychiatric paradigm.

The objective of this paper is to review the international scientific literature published on the impact of the migration process on mental health.

We propose a review of the international scientific literature published in recent years on psychiatry and migration.

We present the case of a 27-year-old male, diagnosed with paranoid schizophrenia, who arrived in the Canary Islands after a 2-year migration process from his country of origin (Senegal).

The limits between normality and pathology of certain types of behavior vary from one culture to another.

In the case of a patient with a mental disorder who has undergone a migration process, an approach based on the cultural formulation of the case should be made, taking into account the process of adaptation to the culture of the host country, as well as the impact of the culture of origin on the patient’s interpretation of his or her psychopathology.

Culture can influence the acceptance or rejection of a diagnosis and treatment, affecting the course of the disease and recovery.

Therefore, understanding the cultural context in which the disease is experienced is essential for a good diagnostic evaluation and effective clinical management.

Digital interventions have been found to be successful in preventing occupational mental health concerns, however, they seem to be affected by attrition bias through high attrition rates and differential attrition. Differential attrition arises when the rates of participant dropouts differ across different treatment conditions and is considered a significant challenge to internal validity.

We aimed at systematically review and meta-analyse differential attrition of digital mental health interventions in the workplace setting.

On January 2, 2022, we performed a search in the following electronic databases: PubMed, Scopus, and Web of Science Core. We utilized a combination of terms from five distinct areas, namely mental health, intervention, workplace, implementation, and study design. The study encompassed adult employees who took part in a randomized control trial aimed at preventing mental health issues in the workplace through an online intervention. A team of six reviewers collaborated on the study selection process, while two independent researchers conducted the data extraction for the selected studies. We performed a meta-analysis of the log-transformed relative attrition rates of the included studies using a random-effects model with limited maximum-likelihood (REML) estimation to account for the degree of heterogeneity.

A total of 19 studies were included in the meta-analysis. For baseline to post-intervention, the average total attrition was 26.27% (SD = 21.16%, range = 0 – 66.3%) and the random effects model revealed a higher attrition rate in the intervention group compared to the control group, with a pooled risk ratio of 1.05 (95% CI: 1.01 - 1.10, p = .014). For baseline to follow-up measurement the average total attrition was 27.71% (SD = 20.80%, range = 0 – 67.78%), however, in this case the random effects model did not indicate a higher attrition in the intervention group when compared to the control group (pooled risk ratio = 1.05, 95% CI: 0.98 – 1.12, p = .183).

There is an indication of higher attrition in the intervention group as compared to the control group in occupational e-mental health interventions from baseline to post-intervention, however this does not seem to be the case for baseline to follow-up attrition. These results should be taken into account in the design process of studies and statistical analyses should be adapted to counteract the bias that could result from differential attrition.

Evidence from observational and genetic studies suggests a bidirectional relationship between loneliness and psychosis. To our knowledge, no previous study has assessed the association between loneliness in childhood and first-episode psychosis (FEP).

We aimed to assess the association between loneliness in childhood and the odds of FEP and clinical variables of interest (i.e., diagnosis and clinical and functional severity) in FEP and to explore gender differences in this association.

This was an observational, case-control study, based on the AGES-CM cohort, a longitudinal prospective study including patients with FEP ages 7-40, their first-degree relatives, and an age- and sex-matched sample of controls in seven university hospitals in the region of Madrid. We assessed loneliness in childhood with the question “Have you ever felt lonely for more than 6 months before the age of 12” and objetive social isolation with the peer relationships item from the childhood subscale of the Premorbid Adjustment Scale. We conducted logistic and linear regression analyses to assess the association between childhood loneliness and i) the odds of presenting a FEP and ii) clinical variables of interest (diagnosis and scores on positive, negative, general, depressive, and manic symptoms and functioning), while adjusting for demographic variables.

The study sample comprised 285 patients with FEP (32.6% female, age 24.50 ± 6.2 years) and 546 controls (48.7% female, age 25.93 ± 5.5 years). Loneliness in childhood was associated with increased odds of FEP (adjusted odds ratio; aOR: 2.17, 95% CI [1.40-3.51], p=.002). This association remained significant after controlling for objective social isolation in childhood (aOR:2.70, IC 95% [1.58-4.62], p<.001).

The effect of the association was stronger in females (aOR:4.74, 95% CI [2.23-10.05], p<.001) than in males (aOR:1.17, IC 95% [0.63-2.19], p=.623). In females with FEP, loneliness in childhood was significantly associated with increased odds of receiving a diagnosis of other psychosis (aOR:0.155, 95% CI [0.048-0.506], p=.002) relative to an SSD diagnosis. In the FEP sample, loneliness in childhood was associated with greater severity of positive and affective symptoms and worse functioning.

Loneliness in childhood is associated with increased odds of FEP and clinical variables of interest. This suggests the potential role of this phenotype as an early risk marker for psychosis that could help guide targeted interventions.

Individuals who are unable to meet their basic needs are more likely to respond reactively to their immediate social and financial hardships with behaviors that lead to “diseases of despair,” which include suicide, drug overdose, and alcohol-induced liver diseases. We sought to assess the feasibility of a community-to-clinic referral approach for diseases of despair-related behaviors.

Guided by the Model for Adaptation Design and Impact, we adapted existing clinical risk assessments into a six-item screener and integrated it into the PA 211 Southwest helpline’s workflow. The screener was created to identify helpline callers at risk for suicidal ideation/behavior, alcohol abuse, drug use, and those in need of seasonal flu vaccination. The screener was implemented from December 2020 to March 2021. We invited at-risk individuals who accepted a service referral to complete baseline and follow-up surveys to learn about their satisfaction with screening and use of referrals.

2,868 callers were invited to take the screener, with 37% (n = 1047) participation. Among screened callers, 19% (n = 196) were at risk of alcohol abuse, 11% (n = 118) for drug use, 9% (n = 98) for suicidal ideation/behavior, and 54% (n = 568) needed flu vaccination. Of those, 265 callers accepted at least one of the offered referrals. Forty-seven individuals took our surveys, with almost half of them (n = 22) reported engaging with a referral and 90% recommended the helpline for health referrals.

Our findings demonstrate the feasibility of using existing community infrastructure and social service systems to actively screen and link at-risk individuals to needed health referrals in their communities.

Cancer patients are among the most vulnerable populations during and after a disaster. We evaluated the impact of treatment interruption on the survival of women with gynecologic cancer in Puerto Rico following Hurricanes Irma and María.

A retrospective cohort study among a clinic-based sample of women with gynecological cancer diagnosed between January 2016 and September 2017 (n = 112) was done. Women were followed from their diagnosis until December 2019, to assess vital status. Kaplan-Meier survival curves and Cox proportional hazards models were performed.

Mean age was 56 (± 12.3) years; corpus uteri (58.9%) was the most common gynecologic cancer. Predominant treatments were surgery (91.1%) and chemotherapy (44.6%). Overall, 75.9% were receiving treatment before the hurricanes, 16.1% experienced treatment interruptions, and 8.9% died during the follow-up period. Factors associated with treatment interruption in bivariate analysis included younger age (≤55 years), having regional/distant disease, and receiving > 1 cancer treatment (P < 0.05). Crude analysis revealed an increased risk of death among women with treatment interruption (HR: 3.88, 95% CI: 1.09-13.77), persisting after adjusting for age and cancer stage (HR: 2.49, 95% CI: 0.69-9.01).

Findings underscore the detrimental impact of treatment interruption on cancer survival in the aftermath of hurricanes, emphasizing the need for emergency response plans for this vulnerable population.
