RESUMO

BACKGROUND: Colombia has high numbers of internally displaced people, forced to migrate due to the conflict. 1 in 3 displaced women undergo pregnancy during adolescence, compared to around 1 in 5 in the non-displaced population, alongside health and resource inequalities between these groups. There is limited qualitative information available from the perspectives of displaced women experiencing adolescent pregnancy. This research explores how structural violence may feature in their experiences. METHODS: Qualitative methods were used. Participants were recruited with purposive sampling, using key informants and snowball sampling technique. 14 semi-structured interviews were conducted in Ciudad Bolívar, Bogotá, involving 11 displaced women who began childbearing age 15-19 in the past 10 years, and 4 participants' mothers. Data was analysed using the theoretical framework of structural violence, and emergent themes categorised using thematic analysis. RESULTS: Pregnancy was considered advantageous in many ways, but this was contradicted by resulting disadvantages that ensued. Structural violence was embedded in life stories, manifesting in poverty and difficulties accessing reliable income, poor access to healthcare and education following pregnancy. Institutional and interpersonal discrimination confounded these challenges. CONCLUSIONS: Pregnancy during adolescence was a contradictory experience, representing both a safety net and a trap due to a complex interplay of structural and cultural violence in everyday survival. Policymakers must consider the importance of the context surrounding adolescent pregnancy and address systematic disadvantages affecting women in these positions.

The violent conflict in Colombia has left many people forced to leave their homes and become 'internally displaced'. Internally displaced women are more likely to become pregnant during their adolescence than non-displaced women. This work tries to understand more about the everyday lives of displaced women who experience adolescent pregnancy, through interviews. The interviews were analysed and results interpreted using the theory of 'structural violence'. Structural violence describes how social structures such as racism, sexism, war and poverty determine life choices, leading to suffering and inequality. The work found that pregnancy and motherhood in adolescence for displaced women was positive in many ways by bringing purpose, status and companionship. However, these women also experienced many challenges after pregnancy, such as exclusion from education and secure employment and difficulty accessing healthcare. This demonstrated that structural violence features in multiple interconnected forms in the daily lives of displaced adolescent mothers. The work urges policymakers to appreciate the complexity of context surrounding adolescent pregnancy and motherhood, and to address the structural disadvantages facing women in these situations.

RESUMO

In Colombia, the long-lasting internal conflict heavily shaped the socio-ecological context and imposed relationships that persisted after the peace agreement was signed in 2016. One question of interest is whether policies or interventions conceived to attain desirable goals for the post-conflict society may be effective or, rather, if the constraints imposed by the conflict scenario might produce unintended effects, either on the environmental or the social side. To explore this issue, we envisaged the socio-ecological system as a parsimonious set of characteristic ecological and social variables within the conflict-related framework and reconstructed their interactions, exploiting elicitation-based information and the literature. We visualized the resulting interactive networks as signed digraphs. Applying the qualitative technique of loop analysis combined with numerical simulations, we predicted the response of the system to policies as drivers of change, such as subsidized credit to capital-intensive activities or policies that increase small farming competitiveness and access to markets. Highlighting causal linkages reveals that the persistence of conflict factors may produce unexpected interdependencies between licit and illicit activities and that, only in a few cases, the persistence of these mechanisms allows synergies between desirable goals.This article is part of the theme issue 'Connected interactions: enriching food web research by spatial and social interactions'.

RESUMO

Introduction: The overvaluation of weight and shape is a diagnostic criterion in eating disorders, except in binge eating disorder (BED), where it has received less attention. This aspect is also not usually analyzed in people with overweight or obesity without an eating disorder. This research aims to identify the indicators of symptomatology, as well as those of self-construction and cognitive structure, that are associated with overvaluation in obesity, either alone or in conjunction with BED. Method: A sample of 102 overweight or obese participants was accessed. The sample was divided into four groups: one without overvaluation or BED (n = 33); a second with overvaluation and without BED (n = 21); a third with BED, but without overvaluation (n = 15), and a fourth with BED and overvaluation (n = 33). The groups completed instruments regarding eating symptomatology, anxiety, depression, and stress. In addition, they were administered the Repertory Grid Technique, a semi-structured interview to evaluate the cognitive structure involved in the construal of the self and others. Results: The factors of overvaluation and the presence of BED independently explained eating symptomatology, and the latter also showed a tendency to influence anxiety, depression, and stress. In terms of cognitive structure, weight polarization was explained by overvaluation, while BED was associated with a high presence of cognitive conflicts. In self-construction, BED was the factor that explained the differences, particularly in Self-Ideal discrepancy. Discussion: The results highlight the importance of overvaluation in obesity, even in the absence of BED. Its evaluation and treatment are recommended. Furthermore, in the case of BED, it is also advisable to evaluate the overvaluation of weight and shape since it can be a severity specifier.

RESUMO

A scoping review of publications about commercial milk formulas intended for or consumed by children 12-36 months (CMF 12-36) was conducted. This review aimed to comprehensively map the existing literature, identify key concepts in the field and understand its evolution through time. A total of 3329 articles were screened and 220 were included, published between 1986 and 2024. Most works were published after 2016 (70.0%) and in high-income countries (71.8%). Original studies were the vast majority (81.8%) of publications. Most publications dealt with feeding practices or analysed the composition and/or contamination of specific products (44.1% and 35.9%), but since the late 2000s, publications about marketing, policy, legislation, and consumer perception started to appear. Most published works (65.5%) did not focus exclusively on CMF 12-36 and included formulas for other demographics or other foods. About half of the works (55.5%) did not consider CMF 12-36 to be a breast milk substitute. We found 81 distinct product denominations used to refer to CMF 12-36, Growing Up Milk was the most common (25.9%). CMF industry was involved in 41.8% of all analysed works, and industry participation and funding were not always clearly informed (22.5% lacked a conflict of interest statement, and 25.5% did not present any information about funding). In the last decade, publications about CMF 12-36 have increased in volume and diversified in scope and subject matter. CMF-industry participation has always been and still is present in the field, so possible vested interests should be taken into account when appreciating the literature.

RESUMO

Disarmament, demobilization, and reintegration (DDR) processes have undergone significant evolution in recent decades, reflecting the complex dynamics of the transition from conflict to peace. This paper presents a comparative analysis of three generations of DDR processes, illustrating the shift from a primarily security-focused approach to a comprehensive strategy that includes socioeconomic development, political participation, and community engagement. In Colombia, a country with a long history of armed conflict, the process of DDR has undergone significant changes. These changes were made to adapt to the intricate realities of war, peace agreements, and social integration. During its evolution, DDR in Colombia has encountered challenges in expanding beyond the traditional scope of disarmament and demobilization to include the crucial aspect of reintegration. This highlights the significance of addressing the varied needs of ex-combatants and ensuring their sustainable integration into civilian life. The findings emphasize the importance of flexible and context-sensitive DDR frameworks that acknowledge the distinct challenges and opportunities of each post-conflict scenario. This provides valuable insights for future peacebuilding efforts worldwide.

RESUMO

Introduction: The Male Warrior Hypothesis (MWH) proposes that sex-specific selective pressures have promoted male cooperation with the ingroup members to outcompete rival groups. However, intergroup conflicts do not occur in isolation and the outcomes of previous competitions may influence group cooperativeness. Since this phenomenon is not well understood, we aimed to shed light on the effect of previous competition outcome on later cooperative behavior under intergroup conflicts. Based on the MWH, we hypothesized that repeated contests between groups could enhance ingroup cooperation, regardless of the outcome of the previous contest because status is at risk, but when competition is not present, participants would move to the symmetric equilibria. Methods: To test this hypothesis, we recruited 246 individuals organized in groups of 6 and measured cooperation using a threshold public good game over two rounds, manipulating the outcome in the first round to create groups of winners and losers. Results: Our results show that intergroup conflict scenarios promoted cooperation in both victory and defeat conditions, whereas, in the control scenario only losers increased their cooperation. Discussion: We argue that winners under the presence of an external threat may enhance in-group cooperation in order to assure their status; whereas, losers may be attempting to regain it.

RESUMO

In Mexico social dynamics are changing toward less traditional arrangements. With a qualitative interview study, we explore the link between marital conflict and mothers' ability to foster healthy dietary habits. Sample consisted of 21 middle-class cohabitating mothers of preschoolers. Results suggests that marital conflict leads women to experiences of tension, ambivalence, or inaction on fostering healthy eating habits. Parents' mismatch in gender beliefs, food preferences, time orientation, and risk aversion play a role in creating disagreements. When men participate, women feel "helped" and grateful, but the forms and extent of desired participation may vary among traditional, ambivalent and non-traditional women.

RESUMO

Infanticide and adoption have been attributed to sexual selection, where an individual later reproduces with the parent whose offspring it killed or adopted. While sexually selected infanticide is well known, evidence for sexually selected adoption is anecdotal. We report on both behaviors at 346 nests over 27 y in green-rumped parrotlets (Forpus passerinus) in Venezuela. Parrotlets are monogamous with long-term pair bonds, exhibit a strongly male-biased adult sex ratio, and nest in cavities that are in short supply, creating intense competition for nest sites and mates. Infanticide attacks occurred at 256 nests in two distinct contexts: 1) Attacks were primarily committed by nonbreeding pairs (69%) attempting to evict parents from the cavity. Infanticide attacks per nest were positively correlated with population size and evicting pairs never adopted abandoned offspring. Competition for limited nest sites was a primary cause of eviction-driven infanticide, and 2) attacks occurred less frequently at nests where one mate died (31%), was perpetrated primarily by stepparents of both sexes, and was independent of population size. Thus, within a single species and mating system, infanticide occurred in multiple contexts due to multiple drivers. Nevertheless, 48% of stepparents of both sexes adopted offspring, and another 23% of stepfathers exhibited both infanticide and long-term care. Stepfathers were often young males who subsequently nested with widows, reaching earlier ages of first breeding than competitors and demonstrating sexually selected adoption. Adoption and infanticide conferred similar fitness benefits to stepfathers and appeared to be equivalent strategies driven by limited breeding opportunities, male-biased sex ratios, and long-term monogamy.

RESUMO

Parallel computing is a current algorithmic approach to looking for efficient solutions; that is, to define a set of processes in charge of performing at the same time the same task. Advances in hardware permit the massification of accessibility to and applications of parallel computing. Nonetheless, some algorithms include steps that require or depend on the results of other steps that cannot be parallelized. Speculative computing allows parallelizing those tasks and reviewing different execution flows, which can involve executing invalid steps. Speculative computing solutions should reduce those invalid flows. Product configuration refers to selecting features from a set of available options respecting some configuration constraints; a not complex task for small configurations and models, but a complex one for large-scale scenarios. This article exemplifies a videogame product line feature model and a few configurations, valid and non-valid, respectively. Configuring products of large-scale feature models is a complex and time-demanding task requiring algorithmic solutions. Hence, parallel solutions are highly desired to assist the feature model product configuration tasks. Existing solutions follow a sequential computing approach and include steps that depend on others that cannot be parallelized at all, where the speculative computing approach is necessary. This article describes traditional sequential solutions for conflict detection and diagnosis, two relevant tasks in the automated analysis of feature models, and how to define their speculative parallel version, highlighting their computing improvements. Given the current parallel computing world, we remark on the advantages and current applicability of speculative computing for producing faster algorithmic solutions.

RESUMO

BACKGROUND: This study explores the impacts of attacks perpetrated in the context of armed conflict, to female health workers in three Colombian territories. METHODS: We conducted a document review of the reports and databases of the Colombian Truth Commission, 17 in-depth semi-structured interviews with experts on the national and regional armed conflict and the medical mission, and 26 female health workers who were victims of attacks. RESULTS: Experts and female health workers reported attacks to health activities, facilities, equipment, and personnel, including attacks to traditional doctors belonging to indigenous communities. The most frequent attacks were threats and retention of health personnel; theft of supplies and medicines; damage and use of infrastructure and means of transport for purposes other than health care; and hinderance of health service provision. The attacks occurred in a framework of structural violence that intersects with poverty, racism, and gender bias. The impacts of these attacks include gender-based violence, significant disruption of the lives of health workers, and physical, emotional, psychological, social, and economic effects on the victims and their families. The government response to protect victims and populations has been absent or insufficient. CONCLUSIONS: Attacks to health care were reported in all the studied territories obstructing adequate health care. Impacts of these attacks affect negatively the professional and personal life of the workers and are aggravated by structural violence and absent or little institutional response.

RESUMO

Foraging decisions involve assessing potential risks and prioritizing food sources, which can be challenging when confronted with changing and conflicting circumstances. A crucial aspect of this decision-making process is the ability to actively overcome defensive reactions to threats and focus on achieving specific goals. The ventral pallidum (VP) and basolateral amygdala (BLA) are two brain regions that play key roles in regulating behavior motivated by either rewards or threats. However, it is unclear whether these regions are necessary in decision-making processes involving competing motivational drives during conflict. Our aim was to investigate the requirements of the VP and BLA for foraging choices in conflicts involving overcoming defensive responses. Here, we used a novel foraging task and pharmacological techniques to inactivate either the VP or BLA or to disconnect these brain regions before conducting a conflict test in male rats. Our findings showed that BLA is necessary for making risky choices during conflicts, whereas VP is necessary for invigorating the drive to obtain food, regardless of the presence of conflict. Importantly, our research revealed that the connection between VP and BLA is critical in controlling risky food-seeking choices during conflict situations. This study provides a new perspective on the collaborative function of VP and BLA in driving behavior, aimed at achieving goals in the face of dangers.

RESUMO

Introducción: En los contextos del conflicto armado convergen actividades que potencialmente pueden producir toxicidad por metales pesados; inclusive, muchas víctimas de artefactos explosivos improvisados portan esquirlas residuales interiorizadas, de composición y potencial toxicidad desconocidas. Ello ha sido poco estudiado. Objetivo: Describir los niveles biológicos de plomo y mercurio en civiles supervivientes de la masacre de Bojayá, su eventual exposición actual, así como signos y síntomas compatibles con toxicidad crónica. Metodología: Estudio observacional descriptivo, tipo serie con 13 casos. Resultados: El 38.46 % de los casos tuvo niveles de plomo en sangre superiores o cercanos al valor límite superior, sin fuentes específicas identificadas. Un 46.15 % tuvo niveles mercuriales superiores o cercanos al límite de referencia, y se los considera exposición ambiental por minería aurífera regional. La valoración clínica toxicológica mostró síntomas y signos clínicos potencialmente asociados con toxicidad crónica por metales. Conclusión: Hubo presencia de residuos de artefactos explosivos en personas con hallazgos sugestivos de toxicidad por plomo o mercurio, sin que pueda afirmarse una relación directa y específica entre los dos aspectos; algunos casos sugieren exposición ambiental para mercurio, y exposición a proyectiles para el plomo, relacionadas con dinámicas del conflicto armado. Son necesarios estudios adicionales para afirmar la existencia de asociaciones causales.

Introduction: In the contexts of armed conflict, activities converge that can potentially produce heavy metal toxicity; including many victims of improvised explosive devices carry internalised residual shrapnel, of unknown composition and potential toxicity. This has been little studied. Objective: To describe the biological levels of lead and mercury in civilian survivors of the Bojayá massacre, their possible current exposure, as well as signs and symptoms compatible with chronic toxicity. Methodology: Descriptive observational study, serial type with 13 cases. Results: 38.46 % of the cases had blood lead levels above or close to the upper limit value, with no specific sources identified. 46.15 % had mercury levels above or close to the reference limit, and were considered environmental exposure from regional gold mining. Clinical toxicological assessment showed clinical signs and symptoms potentially associated with chronic metal toxicity. Conclusion: There was a presence of explosive ordnance residues in individuals with findings suggestive of lead or mercury toxicity, without a direct and specific relationship between the two; some cases suggest environmental exposure for mercury, and projectile exposure for lead, related to the dynamics of the armed conflict. Further studies are needed to affirm the existence of causal associations.

RESUMO

The Peruvian guanaco (Lama guanicoe cacsilensis) is classified as being "in critical danger of extinction" by the government. In this study, we evaluate how the conflict between farmers and guanacos in the Susapaya and Estique Districts, Tacna Department (Southern Peru) may represent a threat to their survival. To evaluate the situation, we 1. Conducted field surveys to monitor guanaco presence, 2. Used available remote sensing data to map guanaco movement, and 3. interviewed the impacted farmers concerning their losses. Remote sensing data showed that sedentary guanaco family groups located in prime steppe vegetation habitats never entered agricultural areas, while field surveys showed that bachelor bands and solitary individuals did, perhaps seeking forage due to growing population pressure. Interview data found that 90% of community farmers felt that guanacos were a problem best resolved by better fencing (45%), hunting (19%), or increased security (16%), and 92% saw no value in the conservation of the species. Hunting is illegal, given the critically endangered status of guanacos in Peru, so additional efforts are needed to both educate those who feel guanacos are a menace and involve them in efforts to preserve the species.

RESUMO

BACKGROUND: Adolescents with type 1 diabetes (T1D) are at increased risk for depression. A history of recurrent depression (HRD) may relate to worse health outcomes than single-episode depression. However, no study has explored this issue among T1D adolescents. PARTICIPANTS AND PROCEDURE: We examined differences in psychosocial and diabetes-related outcomes between T1D adolescents with (G1; n = 33) and without (G2; n = 18) HRD. Participants were 51 youths (aged 12-17 years) enrolled in a depression treatment study. Youths and one caregiver each completed several measures. Using MANOVA, followed by individual ANOVAs, and chi-square tests, we compared groups in continuous and categorical variables, respectively. RESULTS: MANOVA results were significant, F(7, 43) = 3.97, p = .002. Adolescents from G1 obtained higher scores than youths in G2 in self-esteem/guilt problems, cognitive alterations, and sadness due to T1D. Their caregivers reported more burden and rated their offspring as having more internalizing problems, facing more barriers to complying with T1D treatment, and using a medical ID less frequently than their counterparts did. A higher percentage of G1 participants presented clinical anxiety and inadequate glycemic control, and reported a history of major depression. According to caregivers, a higher proportion of G1 members had experienced multiple diabetes-related hospitalizations, were non-compliant with insulin treatment, and lived in homes with a conflictive environment. CONCLUSIONS: Our study documents important differences in outcomes between T1D youths with vs. without any HRD. Clinicians may need an intensive and integrative approach to treat mental and physical aspects of health among these patients.

RESUMO

Background: Trigeminal neuralgia (TN) is a highly disabling facial pain syndrome, historically known as the suicide disease, in which most cases can be cured with appropriate surgical treatment. Case Description: We present the case of a 43-year-old male farmer with acute, self-limiting episodes of shock-like pain on the left side of the face that started in June of 2021. He was diagnosed with TN and was treated with carbamazepine. Magnetic resonance imaging was performed, which revealed an epidermoid cyst (EC) at the prepontine cistern with an extension to the left cerebellopontine angle. The neurosurgery department at our institution was consulted, which performed surgical tumor resection and Vth cranial nerve decompression. During the resection, a neurovascular conflict (NVC) was identified at the root entry zone. After the resection around the nerve and its whole tract was completed, a microvascular decompression (MVD) was performed. Conclusion: TN secondary to EC in association with a NVC is a rare phenomenon, due to the growth pattern of the EC. TN may remit if an appropriate treatment is carried out. In cases of NVC, an MVD is required apart from an appropriate resection to achieve pain relief.

RESUMO

Research suggests that health literacy (HL) is critical in preventing and managing health problems. However, over half of adults in Mexico report having inadequate health literacy. Research suggests the parent-child relationship can be a key predictor of developmental competencies; however, little research has examined how dyadic family interactions relate to HL. This study examined whether parent-child relationship conflict was associated with adolescent health literacy among families living in Mexico. Data from a parent-child dyads in Mexico were gathered using online surveys (N = 746, 373 parent-child dyads). Our findings suggested that child-reported family conflict-but not parent-reported family conflict - was associated with lower adolescent health literacy. Researchers and practitioners should consider how parent-child conflict may impact adolescent health outcomes, and prioritise child reports in data collection.

RESUMO

We investigated the causal impact of conflict-related violence on individual mental health and its potential pathways in Colombia. Using data from before and after the 2016 peace accord between the Colombian government and the Revolutionary Armed Forces of Colombia (FARC), we adopted a difference-in-differences empirical design combined with instrumental variables estimation. We also used formal mediation analysis to investigate a possible mediating role of alcohol consumption in the relationship between conflict exposure and mental health. Our results did not support the hypothesis that changes in exposure to conflict violence after the peace accord causally led to any changes in individual mental health. We were unable to identify a statistically significant mediating effect of alcohol consumption in the relationship between exposure to conflict violence and mental health.

RESUMO

Grounded in developmental and cultural-ecological perspectives, the current study examined trajectories of parent-youth conflict regarding everyday issues across adolescence and into young adulthood. Data came from 246 Mexican-origin families in the southwestern United States with younger siblings (51% female, Mage = 12.8, SD = 0.58), older siblings (Mage = 15.5, SD = 1.57), mothers (Mage = 39.0; SD = 4.6), and fathers (Mage = 41.7; SD = 5.8) and were collected at four time points over an 8-year period. Multilevel modeling analyses revealed linear declines in mother-youth and father-youth conflict across ages 12-22. Youth, but not parent, familism values were associated with variation in parent-youth conflict. This study extends understanding of culturally and developmentally salient processes of mother-youth and father-youth relationships in Mexican-origin families.
