RESUMEN
BACKGROUND: Exposure to potentially traumatic events increases the risk of a person developing a mental disorder. Training community members to offer support to a person during and after a traumatic situation may help lower this risk. This study reports on the cultural adaptation of Australian mental health first aid guidelines for individuals exposed to a potentially traumatic event to the Chilean and Argentinian context. METHODS: A Delphi expert consensus study was conducted with two panels of experts, one of people with lived experience of trauma (either their own or as a carer; n = 26) and another one of health professionals (n = 41). A total of 158 items, drawn from guidelines developed by Australian experts in 2019, were translated to Spanish and evaluated in a two-round survey process. The panellists were asked to rate each item on a five-point Likert scale; statements were included in the final guidelines if 80% of both panels endorsed the item as "essential" or "important". RESULTS: Consensus was achieved on 142 statements over two survey rounds. A total of 102 statements were included from the English-language guidelines, and 40 locally generated statements were accepted in the second round. Local experts endorsed a larger number of items compared to their counterparts in Australia and emphasised the importance of acknowledging the first aider's limitations, both personally and as part of their helping role. Additional items about working as a team with other first responders and considering helping the person's significant others were endorsed by the local panellists. CONCLUSIONS: The study showed a high level of acceptance of the original actions suggested for inclusion in the guidelines for Australia, but also a significant number of new statements that highlight the importance of the adaptation process. Further research on the dissemination of these guidelines into a Mental Health First Aid training course for Chile and Argentina is still required.

BACKGROUND: Psychotic symptoms may be less common than anxiety or affective symptoms, but they are still frequent and typically highly debilitating. Community members can have a role in helping to identify, offer initial help and facilitate access to mental health services of individuals experiencing psychosis. Mental health first aid guidelines for helping a person experiencing psychosis have been developed for the global north. This study aimed to adapt the English- language guidelines for Chile and Argentina. METHODS: A Delphi expert consensus study was conducted with two panels of experts, one of people with lived experience of psychosis (either their own or as a carer; n = 29) and another one of health professionals (n = 29). Overall, 249 survey items from the original English guidelines and 26 items suggested by the local team formed a total of 275 that were evaluated in the first round. Participants were invited to rate how essential or important those statements were for Chile and Argentina, and encouraged to suggest new statements if necessary. These were presented in a second round. Items with 80% of endorsement by both panels were included in the guidelines for Chile and Argentina. RESULTS: Data were obtained over two survey rounds. Consensus was achieved on 244 statements, including 26 statements locally generated for the second round. Almost 20% of the English statements were not endorsed (n = 50), showing the applicability of the original guidelines but also the importance of culturally adapting them. Attributions and tasks expected to be delivered by first aiders were shrunk in favour of a greater involvement of mental health professionals. Self-help strategies were mostly not endorsed and as were items relating to respecting the person's autonomy. CONCLUSIONS: While panellists agreed that first aiders should be aware of human rights principles, items based on recovery principles were only partially endorsed. Further research on the dissemination of these guidelines and development of a Mental Health First Aid training course for Chile and Argentina is still required.

BACKGROUND: Depression is one of the most common mental health problems worldwide and, while prevalence rates in Latin America are relatively high, most people who meet the criteria for diagnosis do not receive treatment. Family and friends of a person with depression can play an important role in supporting a person to seek and engage with treatment. However, many people do not have the necessary skills or confidence to help. English-language mental health first aid guidelines have been developed to support people to provide such help. The aim of this study was to culturally adapt these guidelines for Chile and Argentina. METHODS: A Delphi expert consensus study was conducted with two expert panels, one of people with lived experience of depression (either their own or as a carer; n = 26) and one of health professionals (n = 29). Overall, 172 statements from the English-language guidelines were translated and compiled into a questionnaire. Participants were asked to rate statements based on how essential or important those statements were for Chile and Argentina and to suggest new statements if necessary. RESULTS: Data were obtained over two survey rounds. Consensus was achieved on 172 statements. A total of 137 statements were adopted from the English-language guidelines, whereas 35 new endorsed statements were generated from panel suggestions. There were similarities between the English-language guidelines and those for Chile and Argentina. The adapted guidelines did not include some of the items from the English-language guidelines related to commenting on a person's strengths or making judgements about their character, and also incorporated new items related to the incorporation of sociocultural considerations as causes of depression and attention to inequities in mental health. CONCLUSIONS: The significant number of new items underscores the importance of undertaking a careful process of cultural adaptation. Further research on dissemination and incorporation of the guidelines into the Mental Health First Aid training course for Chile and Argentina is still required.

BACKGROUND: Suicide continues to pose a significant global public health challenge and ranks as one of the leading causes of death worldwide. Given the prevalence of suicide risk in the community, there is a significant likelihood of encountering individuals who may be experiencing suicidal thoughts or plans, creating an opening for non-health professionals to offer support. This study aims to culturally adapt the original Australian Mental Health First Aid Guidelines for suicide risk to the Chilean and Argentine context. METHODS: A two-round Delphi expert consensus study was conducted involving two panels, one comprising individuals with personal experience in suicide thoughts/attempts or caregiving for those with such experiences (n = 18), and the other consisting of professionals specialized in suicide assessment and support for individuals at risk (n = 25). They rated a total of 179 items mainly derived from guidelines developed by Australian experts and translated into Spanish (168), and new items included by the research team (11). The panel members were requested to assess each item utilizing a five-point Likert scale. During the second round, items that received moderate approval in the initial round were re-evaluated, and new items suggested by the local experts in the first round were also subjected to evaluation in the next round. Inclusion in the final guidelines required an 80% endorsement as "essential" or "important" from both panels. RESULTS: Consensus of approval was reached for 189 statements. Among these, 139 statements were derived from the English-language guidelines, while 50 locally generated statements were accepted during the second round. A significant difference from the original guideline was identified concerning the local experts' reluctance to discuss actions collaboratively with adolescents. Furthermore, the local experts proposed the inclusion of an entirely new section addressing suicide risk in older individuals, particularly focusing on suicide methods and warning signs. CONCLUSIONS: A Delphi expert consensus study was conducted to culturally adapt mental health first aid guidelines for assessing suicide risk in Chile and Argentina. This study involved professionals and individuals with lived experience. While many items were endorsed, some related to inquiring about suicide risk and autonomy, particularly for adolescents, were not. An additional section for older individuals was introduced. Future research should explore the implementation and impact of these adapted guidelines in training courses. This is vital for enhancing mental health support and implementing effective suicide prevention strategies in Chile and Argentina.

OBJECTIVE: Report the prevalence of depression, resilience, and risk factors among healthcare workers (HCW) during Co-vid-19. MATERIALS AND METHODS: This is an observational cross-sectional study derived from the ongoing international, prospective multicentric study "The COVID-19 HEalth caRe wOrk-Ers Study" (HEROES). A convenience sample of 2 127 HCW was obtained from Chiapas and Jalisco between May 19th and July 24th 2020. Depression was assessed using the Patient Health Questionnaire, resilience with the Brief Resilience Scale and a Covid risk scale was developed. Model-adjusted prevalence ratios (PRs) and an additive interaction model were performed. RESULTS: Moderate-severe depression was found in 16.6% of HCW. Those from Jalisco, physicians, in hospitals, with chronic illness and mental health history were more depressed. The interaction between resilience and risk showed that, compared to those with no risk and medium/high resilience, HCW at risk with medium/high resilience had a 2.38 PR for depression while those at risk and low resilience had a PR of 5.83. CONCLUSION: This evidence points the need to develop strategies to enhance resilience and reduce the risk in HCW.

Objectives. To assess the baseline prevalence of mental health conditions and associated exposures in a cohort of health care workers (HCWs) in Guatemala. Methods. We analyzed baseline information from the 2020 Web-based COVID-19 Health Care Workers Study (HEROES)-Guatemala. Outcomes included mental distress and depressive symptoms. Exposures included COVID-19 experiences, sociodemographic characteristics, and job characteristics. We used crude and adjusted Poisson regression models in our analyses. Results. Of the 1801 HCWs who accepted to participate, 1522 (84.5%) completed the questionnaire; 1014 (66.8%) were women. Among the participants, 59.1% (95% confidence interval [CI] = 56.6, 61.5) screened positive for mental distress and 23% (95% CI = 20.9, 25.2) for moderate to severe depressive symptoms. COVID-19 experiences, sociodemographic characteristics, and job characteristics were associated with the study outcomes. Participants who were worried about COVID-19 infection were at higher risk of mental distress (relative risk [RR] = 1.47; 95% CI = 1.30, 1.66) and depressive symptoms (RR = 1.51; 95% CI = 1.17, 1.96). Similarly, the youngest participants were at elevated risk of mental distress (RR = 1.80; 95% CI = 1.24, 2.63) and depressive symptoms (OR = 4.58; 95% CI = 1.51, 13.87). Conclusions. Mental health conditions are highly prevalent among Guatemalan HCWs. (Am J Public Health. 2022;112(S6):S602-S614. https://doi.org/10.2105/AJPH.2021.306648).

Objectives. To investigate associations between COVID-19-related factors and depressive symptoms among primary care workers (PCWs) in São Paulo, Brazil, and to compare the prevalence of probable depression among PCWs before and during the pandemic. Methods. In a random sample of primary care clinics, we examined 6 pandemic-related factors among 828 PCWs. We used multivariate Poisson regression with robust variance to estimate prevalence ratios for probable depression. We assessed the prevalence of probable depression in PCWs before and during the pandemic in 2 comparable studies. Results. Adjusted prevalence ratios were substantial for insufficient personal protective equipment; experiences of discrimination, violence, or harassment; and lack of family support. Comparisons between PCWs before and during the pandemic showed that the prevalence of probable depression among physicians, nurses, and nursing assistants was higher during the pandemic and that the prevalence among community health workers was higher before the pandemic. Conclusions. Our findings indicate domains that may be crucial to mitigating depression among PCWs but that, with the exception of personal protective equipment, have not previously been examined in this population. It is crucial that governments and communities address discriminatory behaviors against PCWs, promote their well-being at work, and foster family support.

BACKGROUND: Among all psychoactive substances, alcohol consumption presents the most significant public health problem and is a leading risk factor for overall disease burden in Latin America. However, most people who meet criteria for a substance use disorder do not receive treatment in primary or secondary care sources. Community members can play a role in helping people to seek help as they are likely to encounter people experiencing problem drinking and recognize the signs. However, many do not have adequate mental health first aid knowledge or skills to provide help. We aimed to culturally adapt the existing English-language mental health first aid guidelines for helping someone with problem drinking for Argentina and Chile. METHODS: The Delphi consensus method was used to determine the importance of helping actions translated from the English-language guidelines and to add new actions suggested by expert panellists. The importance of each statement was rated by two expert panels. Panel one included people with lived experience (either their own or as a support person, n = 23) recruited in Argentina and panel two included health professionals (n = 31) recruited in Argentina and Chile. RESULTS: Overall, 165 helping actions were endorsed by panellists across two consecutive survey rounds. Endorsed items included 132 of the 182 items translated into Spanish from the English-language guidelines and 33 of the 61 new items generated from panellists' comments in the first survey round. CONCLUSIONS: While there were some similarities in recommended helping actions between English-speaking countries, and Argentina and Chile, key differences were seen in attitudes to low-risk drinking. While there was a relatively high level of agreement between health professionals and people with lived experience, some divergence of opinion was seen, particularly in the area of commitment to recovery as a condition for help. Future research should explore the implementation of the guidelines.

BACKGROUND: Preliminary country-specific reports suggest that the COVID-19 pandemic has a negative impact on the mental health of the healthcare workforce. In this paper, we summarize the protocol of the COVID-19 HEalth caRe wOrkErS (HEROES) study, an ongoing, global initiative, aimed to describe and track longitudinal trajectories of mental health symptoms and disorders among health care workers at different phases of the pandemic across a wide range of countries in Latin America, Europe, Africa, Middle-East, and Asia. METHODS: Participants from various settings, including primary care clinics, hospitals, nursing homes, and mental health facilities, are being enrolled. In 26 countries, we are using a similar study design with harmonized measures to capture data on COVID-19 related exposures and variables of interest during two years of follow-up. Exposures include potential stressors related to working in healthcare during the COVID-19 pandemic, as well as sociodemographic and clinical factors. Primary outcomes of interest include mental health variables such as psychological distress, depressive symptoms, and posttraumatic stress disorders. Other domains of interest include potentially mediating or moderating influences such as workplace conditions, trust in the government, and the country's income level. RESULTS: As of August 2021, ~ 34,000 health workers have been recruited. A general characterization of the recruited samples by sociodemographic and workplace variables is presented. Most participating countries have identified several health facilities where they can identify denominators and attain acceptable response rates. Of the 26 countries, 22 are collecting data and 2 plan to start shortly. CONCLUSIONS: This is one of the most extensive global studies on the mental health of healthcare workers during the COVID-19 pandemic, including a variety of countries with diverse economic realities and different levels of severity of pandemic and management. Moreover, unlike most previous studies, we included workers (clinical and non-clinical staff) in a wide range of settings.

BACKGROUND: Self-stigma is a dimension of stigma concerning how individuals internalize negative attributes and discriminate against their own selves. Dementia is a stigmatizing condition, and there is a paucity of research exploring the manifestations and implications of self- stigma in people living with dementia in various contexts. AIM: To examine how self-stigma manifests in the experiences of people living with early-stage dementia in Santiago, Chile. PARTICIPANTS: Six men and five women living with early-stage dementia of the Alzheimer's type, aged between 64 and 82 years old (mean = 70). METHODS: One-on-one interviews were conducted, focusing on the experience of people living with early-stage dementia to provide insights on how self-stigma manifests. Interviews were analyzed with a qualitative content analysis approach using Corrigan's social cognitive model of self-stigma (2016). RESULTS: Self-stigma manifested as devaluation and blame at a cognitive level, and as restriction of participation at a behavioral level. Families and dementia education emerged as contextual elements that influenced the internalization of negative attributes in the participants' experiences. CONCLUSIONS: Consistent with previous qualitative research, we found that self-stigma has negative consequences as it concerns emotions, self-prejudices, and self-discrimination. This study provides distinctive insights on the process of internalization of stigma and the influence of external elements. Self-stigma remains an understudied but important feature of the dementia experience, an understanding of which can lead to developing and testing supportive approaches upon diagnosis to minimize its adverse effects.

Objetivos: Avaliar a prevalência basal de condições de saúde mental e exposições associadas em uma coorte de trabalhadores da saúde (TS) na Guatemala. Métodos: Analisamos as informações da linha de base do estudo on-line sobre trabalhadores da saúde e a COVID-19 (HEROES), realizado em 2020 na Guatemala. Os desfechos incluíram angústia debilitante e sintomas de depressão. As exposições incluíram experiências com a COVID-19, características sociodemográficas e características do trabalho. Usamos em nossas análises modelos de regressão bruta e ajustada de Poisson. Resultados: Dos 1801 TS que concordaram em participar, 1522 (84,5%) preencheram o questionário, sendo que 1014 (66,8%) eram mulheres. Dentre esses participantes, 59,1% (intervalo de confiança [IC] de 95%=56,6; 61,5) apresentaram resultado positivo na triagem de angústia debilitante e 23% (IC 95%=20,9, 25,2) apresentaram resultado positivo para sintomas de depressão moderados a graves. Experiências com COVID-19, e características sociodemográficas e de trabalho apresentaram associação com os resultados do estudo. Os participantes que estavam preocupados com infecção por COVID-19 apresentaram maior risco de angústia debilitante (risco relativo [RR]=1,47; IC95%=1,30; 1,66) e sintomas de depressão (RR=1,51; IC 95% =1,17; 1,96). Da mesma maneira, os participantes mais jovens apresentaram alto risco de apresentarem angústia debilitante (RR=1,80; IC 95%=1,24; 2,63) e sintomas de depressão (OR=4,58; IC 95%=1,51; 13,87). Conclusões: Condições de saúde mental são altamente prevalentes entre os guatemaltecos.
RESUMEN
The components of metabolic syndrome (MetS) and hepatogastrointestinal diseases are widespread worldwide, since many factors associated with lifestyle and diet influence their development and correlation. Due to these growing health problems, it is necessary to search for effective alternatives for prevention or adjuvants in treating them. The positive impact of regulated microbiota on health is known; however, states of dysbiosis are closely related to the development of the conditions mentioned above. Therefore, the role of prebiotics, probiotics, or symbiotic complexes has been extensively evaluated; the results are favorable, showing that they play a crucial role in the regulation of the immune system, the metabolism of carbohydrates and lipids, and the biotransformation of bile acids, as well as the modulation of their central receptors FXR and TGR-5, which also have essential immunomodulatory and metabolic activities. It has also been observed that they can benefit the host by displacing pathogenic species, improving the dysbiosis state in MetS. Current studies have reported that paraprobiotics (dead or inactive probiotics) or postbiotics (metabolites generated by active probiotics) also benefit hepatogastrointestinal health.

This study explores the beliefs and attitudes about the psychosocial mechanisms of peer support work among users who participated in Critical Time Intervention-Task Shifting (CTI-TS), which tested the acceptability and feasibility of a peer support work model to improve community-based mental health care for individuals with psychosis in Latin America. We conducted a secondary analysis of 15 in-depth interviews with CTI-TS participants in Chile, using the framework method and defined the framework domains based on five major mechanisms of peer support work identified by a recent literature review. The analysis revealed that users' perceptions of peer support work mechanisms were strongly shaped by personal motivations, beliefs about professional hierarchies, familial support, and the Chilean mental health system's incipient recovery orientation. The findings underscore the importance of adopting culturally tailored strategies to promote peer support work, such as involving mental health professionals and fostering equal-powered relationships between PSWs and users.

The objective of this study was to compare the effects of the incorporation of microcapsules or nanoemulsions with Opuntiaoligacantha on the quality of fresh cheese. Three treatments were established: Control, cheese with microcapsules (Micro), and cheese with nanoemulsion (Nano). The parameters evaluated were physicochemical (moisture, ash, fat, proteins, and pH), microbiological (mesophilic aerobic bacteria, mold-yeast, and total coliforms), functional (total phenols, flavonoids, and antioxidant capacity), and texture (hardness, elasticity, cohesion, and chewiness) during storage for 45 days at 4 °C. The results showed that adding microcapsules and nanoemulsion did not affect the physicochemical parameters of the cheese. Total coliforms decreased in all samples from the first days of storage (Control: 4.23 ± 0.12, Micro: 3.27 ± 0.02, and Nano: 2.68 ± 0.08 Log10 CFU), as well as aerobic mesophiles and mold-yeast counts. Regarding the functional properties, an increase in total phenols was observed in all treatments. The texture profile analysis showed that the addition of microcapsules and nanoemulsion influenced hardness (Control: 8.60 ± 1.12, Micro: 1.61 ± 0.31, and Nano: 3.27 ± 0.37 N). The antimicrobial effect was greater when nanoemulsions were added, while adding microcapsules influenced the antioxidant activity more positively.

BACKGROUND: Healthcare workers' mental health was affected by SARS-CoV-2 pandemic. AIM: To evaluate healthcare workers' mental health and its associated factors during the pandemic in Chile. MATERIAL AND METHODS: An online self-reported questionnaire was designed including the Goldberg Health Questionnaire, the Patient Health Questionnaire, (PHQ-9), and the Columbia-Suicide Severity Rating Scale among other questions. It was sent to 28,038 healthcare workers. RESULTS: The questionnaire was answered by 1,934 participants, with a median age of 38 years (74% women). Seventy five percent were professionals, and 48% worked at a hospital. Fifty nine percent of respondents had a risk of having a mental health disorder, and 73% had depressive symptoms. Significant associations were found with sex, workplace, and some of the relevant experiences during the pandemic. Fifty one percent reported the need for mental health support, and 38% of them received it. CONCLUSIONS: There is a high percentage of health workers with symptoms of psychological distress, depression, and suicidal ideas. The gender approach is essential to understand the important differences found. Many health workers who required mental health care did not seek or received it.

BACKGROUND: Studies on the long-term consequences of torture in survivors in Chile have only addressed the consequences for mental health, leaving aside the physical consequences. AIM: To report the causes of death in the universe of victims of the Chilean civic-military dictatorship recognized by the Reports of the National Commission for Political Prison and Torture (CNPPT) and the Advisory Commission for the qualification of Disappeared Detainees, Politically Executed individuals and Victims of Political Prison and Torture. MATERIAL AND METHODS: The causes of death, age at the time of death, sex, political context of death and opportunity of repair up to June 2016 are described in 38,254 victims of the Chilean civic-military dictatorship. RESULTS: Of the universe of 38,254 victims, 9,152 (23.9%) died until June 2016. The median age at death was 68 years. The main causes of death were malignant tumors in 28%, cardiovascular diseases in 27%, respiratory diseases in 10%, digestive diseases in 9% and external causes in 8%. CONCLUSIONS: These results can inform prevention and treatment strategies for victims of the Chilean dictatorship.

BACKGROUND: The amino acid taurine (2-Aminoethanesulfonic acid) modulates inhibitory neurotransmitter receptors. This study aimed to determine if the dual action of taurine on GABAC-ρ1R relates to its structure. To address this, we tested the ability of the structurally related compounds homotaurine, hypotaurine, and isethionic acid to modulate GABAC-ρ1R. RESULTS: In Xenopus laevis oocytes, hypotaurine and homotaurine partially activate heterologously expressed GABAC-ρ1R, showing an increment in its deactivation time with no changes in channel permeability, whereas isethionic acid showed no effect. Competitive assays suggest that hypotaurine and homotaurine compete for the GABA-binding site. In addition, their effects were blocked by the ion-channel blockers picrotixin and Methyl(1,2,5,6-tetrahydropyridine-4-yl) phosphinic acid. In contrast to taurine, co-application of GABA with hypotaurine or homotaurine revealed that the dual effect is present separately for each compound: hypotaurine modulates positively the GABA current, while homotaurine shows a negative modulation, both in a dose-dependent manner. Interestingly, homotaurine diminished hypotaurine-induced currents. Thus, these results strongly suggest a competitive interaction between GABA and homotaurine or hypotaurine for the same binding site. "In silico" modeling confirms these observations, but it also shows a second binding site for homotaurine, which could explain the negative effect of this compound on the current generated by GABA or hypotaurine, during co-application protocols. CONCLUSIONS: The sulfur-containing compounds structurally related to taurine are partial agonists of GABAC-ρ1R that occupy the agonist binding site. The dual effect is unique to taurine, whereas in the case of hypotaurine and homotaurine it presents separately; hypotaurine increases and homotaurine decreases the GABA current.

OBJECTIVES: To assess the quality of consultation liaison across all primary health care centers in Chile, and its potential relationship with the psychiatric hospitalization rate. METHODS: We carried out a countrywide ecological cross-sectional study on 502 primary health centers in 275 municipalities (87.3% of total primary health centers in Chile) during 2009. We characterized the presence of consultation liaison using four criteria: availability, frequency, continuity of participants, and continuity across care levels. We also created a dichotomous variable called "optimal consultation liaison" for when all four criteria were met. A quasi-Poisson regression model was used to estimate the rate of hospitalization due to different psychiatric disorders, adjusting by population attributes. RESULTS: Of the primary health centers, 28.3% of them had had optimal consultation liaison during the preceding year, concentrated in the poorest and richest municipalities. Continuity of care was the criterion that was met least often (38.3%). The presence of optimal consultation liaison at the municipal level was associated with fewer psychiatric discharges, with the following incidence rate ratios and 95% confidence intervals (CIs): schizophrenia, 0.65 (95% CI: 0.49-0.85); other psychoses, 0.68 (95% CI: 0.52-0.89); and personality disorders, 0.66 (95% CI: 0. 49-0.89). Municipalities with optimal consultation liaison showed 2.44 fewer total psychiatric discharges per 10 000 inhabitants, although without reaching statistical significance (-0.85 to 5.70). CONCLUSIONS: Using a nationally representative sample, we found that consultation liaison in primary care was associated with having fewer psychiatric hospitalizations. More studies are required to understand the role of each component of consultation liaison.

The objective of the study was to evaluate the psychometric properties of the Edinburg Postnatal Depression Scale (EPDS) to detect depression during pregnancy in Chile. The EPDS was applied to a sample of 111 pregnant women, who were attending an antenatal appointment in primary care centers. The Beck Depression Inventory (BDI-I) was used to assess the convergent validity, and the Depressive Episode module of the MINI was used to identify cases. The factor analysis showed that there was a good fit, with a factor model that explains 57.6 % of the total variance. There was a high degree of internal consistency (Cronbach's α = 0.914) and good convergent validity with the BDI-I (rho = 0.850, p < 0.001). The EPDS was capable of differentiating cases of depression from non-cases. The best cutoff point was between 12 and 13, corresponding to an overall accuracy of 87.4 %. The questionnaire has good psychometric properties and can be useful for detecting cases of depression during pregnancy.
