RESUMO

(analítico) El servicio militar obligatorio en el Perú ha generado debates y controversias por la violencia con el que opera, tanto al obligar como al maltratar e incluso torturar a los jóvenes secuestrados. Recién a fines de los años 90 se demostraría la crueldad con la que se operaba, desmantelándose en el 2000. El artículo busca identificar dicha violencia mediante el encauzamiento que operaría en durante la década de 1960. Se aplicaron un total de 28 entrevistas a hombres y mujeres entre los 60 y 83 años. Como hipótesis se propone el uso de la discriminación y del autoritarismo para degradar a los sectores más populares del país. Así, las estrategias biopolíticas denigrantes instaladas persuadirían a la población de la necesidad de tales levas militares incurriendo en un juvenicidio legalizado.

(analytical) Compulsory military service in Peru has generated debates and controversies due to the violence with which it operates, both by forcing and mistreating and even torturing kidnapped youths. Only at the end of the 1990s would the cruelty with which it was operated be demonstrated, dismantling it in the year 2000. The article seeks to identify said violence through the channeling that would operate during the 1960s. Methodologically, a total of 28 interviews with men and women are applied between 60 and 83 years old. As a hypothesis, the use of discrimination and authoritarianism to degrade the most popular sectors of the country is proposed. Thus, the installed demeaning biopolitical strategies would persuade the population of the need for such levies, incurring in a legalized juvenile murder.

RESUMO

OBJECTIVES: To analyze case reports with individual patient data belonging to the Armed Forces submitted to specific physical or military combat training that was affected by rhabdomyolysis and identify factors that influenced the diagnosis and clinical evolution of the syndrome. CONTENT: We conducted a systematic review following the PRISMA guidelines and registered on PROSPERO (CRD42021242465). We searched MedLine (via PubMed), Scopus, Cochrane, Lilacs, SciELO, CINAHL, Web of Science, SPORTDiscus, ScienceDirect, and PEDro databases for studies that reported cases of military personnel affected by rhabdomyolysis. SUMMARY AND OUTLOOK: Thirteen studies met the inclusion criteria. Forty-nine individual cases of rhabdomyolysis were analyzed. From them, it was possible to identify several associated factors, which were responsible for developing rhabdomyolysis in military personnel. Thirty military personnel (60%) practiced physical training and 20 (40%) practiced specific military combat training. The creatine kinase (CK) peak ranged from 1,040 to 410,755 U/L, with an average of 44.991 U/L, and 14 (28%) of the cases reported alteration of renal function and four militaries (8%) evolved to death condition. Physical activities performed strenuously and without proper planning conditions such as room temperature, the period without adequate water intake, the amount of equipment used during the activity contributed to the development of rhabdomyolysis in the cases of military personnel analyzed in the present study. Therefore, it is recommended that future studies investigate the relationship between the prevalence of rhabdomyolysis cases and the severity of its consequence when associated with progressive methods of training, hydration control, acclimatization to austere environments, monitoring for the existence of hereditary diseases, and control of the use of supplementary nutritional substances.

RESUMO

Abstract Background: Brain Derived Neurotrophic Factor (BDNF) serum levels change with age, physical exercise, and neuropsychiatric disorders such as dementia, depression, anxiety, schizophrenia, and bipolar disorder. Military personnel are physically and mental training with an increased risk of developing mental disorders. Objective: The main objective of this study was determinate the BDNF serum levels in four military samples. 132 participants, administrative personnel (control) and three different Special Operations Forces (SOF) groups participated in the study. Methods: A first group of SOFS was on a training course (SOF-TC), second group exposed to 48 hours of operational stress (SOF-48hS) and third group exposed to two-weeks of operational stress (SOF-2wS). The mini interview was conducted and CAPS, and BNF levels were determined by ELISA assays. Results: Differences in age, were evaluated by ANOVA post-hoc Tukey´s. Differences in BNDF levels are evaluated by the Kruskal-Wallis test post hoc Dunn's. Spearman's correlation was used to analyze the relationship between BDNF and age. The SOF-TC had a BDNF elevation in comparison with Control group that could be related to age differences or the physical and mental training.SOF-2wS had decreased BDNF levels in comparison to the other groups that could be related to the psychosocial stress or other mental disorders such as PTSD. That group, 2 participants showed signs of PTSD. Conclusion: BDNF levels are an accurate method for the evaluation of mental health to prevent, diagnose & treat mental disorders in military personnel exposed to operational stress.

Resumen Introducción: Los niveles séricos del factor neurotrófico derivado del cerebro (BDNF) cambian con la edad, el ejercicio físico y los trastornos neuropsiquiátricos como la demencia, la depresión, la ansiedad, la esquizofrenia y el trastorno bipolar. El personal militar está en formación física y mental con un mayor riesgo de desarrollar trastornos mentales. Objetivo: El objetivo principal de este estudio fue determinar los niveles séricos de BDNF en cuatro muestras militares. Participaron en el estudio 132 individuos entre personal administrativo (control) y tres grupos diferentes de Fuerzas de Operaciones Especiales (SOF). Métodos: Un primer grupo de SOFS estaba en un curso de capacitación (SOF-TC), el segundo grupo expuesto a 48 horas de estrés operativo (SOF-48hS) y el tercer grupo expuesto a dos semanas de estrés operativo (SOF-2wS). Se realizó la minientrevista y se determinaron los niveles de CAPS y BNF mediante ensayos ELISA. Resultados: Las diferencias en edad, se evaluaron mediante ANOVA post hoc de Tukey. Las diferencias en los niveles de BNDF se evalúan mediante la prueba de Dunn post hoc de Kruskal-Wallis. Se utilizó la correlación de Spearman para analizar la relación entre BDNF y la edad. El SOF-TC tuvo una elevación de BDNF en comparación con el grupo control que podría estar relacionado con las diferencias de edad o el entrenamiento físico y mental, tal como PTSD. En ese grupo, dos participantes mostraron signos de PTSD. Conclusión: Los niveles de BDNF son un método preciso para la evaluación de la salud mental para prevenir, diagnosticar y tratar los trastornos mentales en el personal militar expuesto al estrés operativo.

RESUMO

ABSTRACT The fundamental objective of military field training exercises (FTX) is to prepare military personnel for real-life operations through simulated scenarios. These training sessions often require extreme physical efforts with prolonged, high-intensity exercises that can be combined with food restrictions and partial, or total, sleep deprivation. Such conditions can compromise an individual's physical performance and cause tissue damage, thus affecting their health. This study aimed to perform a systematic review of the literature to identify studies that measured the changes in hormone levels and biomarkers of cellular injury and oxidative stress resulting from FTX with high levels of energy expenditure combined with food and sleep restrictions. PubMed and the Scopus database were searched for articles that combined physical effort/food restriction/sleep deprivation with military training. The initial database search identified 158 articles that were reduced to 18 after confirmation. Significant reductions were reported in thyroid hormones, T3, T4, and anabolic hormones such as testosterone, insulin and androstenedione. An exception for GH was found, which increased throughout FTX. Less distinct responses to FTX were observed with cortisol, TSH and LH. The presence of biomarkers for cellular damage (myoglobin, TNF, and CRP) and increased immune response activities were also described. The scarcity of information on oxidative stress, analyses of cellular injury and biomarkers of inflammatory responses warrants the future study of these topics, which could be helpful in facilitating the safe and effective physical preparations of the members of the armed forces.

RESUMO

Abstract Tick-borne pathogens belong to one of the two main groups of occupational biohazards, and occupational exposure to such agents puts soldiers at risk of zoonotic infections, such as those caused by rickettsiae. There are few studies on acarological fauna and occupational risk in military areas in Brazil. Thus, the present study aimed to analyze the diversity of ticks present in the military training areas of municipalities in the Southeast Region of Brazil. The ticks were collected from the selected areas using the dragging and flagging techniques as well as by visual detection on the operators' clothing, and environmental information was also recorded. A total of ten species were collected from the 66 surveyed areas, belonging to five genera and nine species: Amblyomma sculptum, Amblyomma dubitatum, Amblyomma brasiliense, Amblyomma longirostre, Amblyomma aureolatum, Dermacentor nitens, Rhipicephalus spp., Ixodes spp. and Haemaphysalis spp. The frequent presence of tick species in military training areas along with traces and sightings of wild animals, most commonly capybaras (Hydrochoerus hydrochaeris), in most of the studied areas, indicates high levels of exposure of the military to tick vectors of spotted fever group rickettsiae and the possible occurrence of infections among the troops.

Resumo As doenças transmitidas por carrapatos estão entre os dois principais grupos de riscos biológicos ocupacionais. Tal exposição ocupacional de militares os colocam sob maior risco de adquirirem doenças zoonóticas, como infecções rickettsiais, entre outras. No Brasil, há raros estudos sobre fauna acarológica e o risco ocupacional em áreas militares. Neste sentido, o presente estudo teve por objetivo analisar a diversidade de carrapatos presentes em áreas de treinamento militar de municípios da região Sudeste do Brasil. Os carrapatos foram coletados nas áreas através de arrasto de flanela, bandeiramento e/ou coleta nas vestimentas do operador, sendo registradas também informações ambientais. Das 66 áreas pesquisadas, foram coletados 9.374 carrapatos, com uma diversidade de cinco gêneros, distribuídos em dez espécies: Amblyomma sculptum, Amblyomma dubitatum, Amblyomma brasiliense, Amblyomma longirostre, Amblyomma aureolatum, Amblyomma spp., Dermacentor nitens, Rhipicephalus spp., Ixodes spp. e Haemaphysalis spp. A presença frequente de espécies de carrapatos nas áreas de instrução militar, associada aos vestígios e à presença de animais silvestres, mais comumente de capivaras na maioria das áreas estudadas, evidencia uma grande exposição dos militares a carrapatos vetores de rickettsias do Grupo da Febre Maculosa e a possível ocorrência de casos humanos nas tropas.

Se entregó un consentimiento informado previo a la realización del estudio y se siguieron las indicaciones establecidas en la declaraciónn de Helsinki. Los participantes fueron sometidos a un plan de entrenamiento físico con una duración de 4 semanas, en las instalaciones del centro militar. Resultados: Con posterioridad al entrenamiento físico, hubo una disminución significativa de la masa adiposa (p < 0,01), con un aumento de la masa muscular (p < 0,01). No se observaron diferencias significativas en los componentes del somatotipo (Pre: 3,29 - 4,78 - 2,59 vs. Post: 2,73 - 4,72 - 2,73; p = 0,24). Conclusiones: Se concluye que el entrenamiento físico en militares, durante un periodo corto de cuatro semanas, provoca cambios rápidos y significativos en la composición corporal de los soldados; cambios que no alcanzaron a observarse en el somatotipo(AU)

Introduction: The objective of physical training in military training is to develop physical and psychological preparation in adverse environmental conditions. Objective: Determine the changes in body composition and somatotype product of basic physical training in military training for four weeks in conscript soldiers. Methods: 28 men were evaluated (age: 18.9 ± 0.9 years; height: 1.75 ± 0.1 m; weight: 67 ± 8.7 kg; BMI: 22.5 ± 2.4 and ∑6 folds 70.88 ± 26.57) who entered the period of military training in the Chilean Air Force, Quintero headquarters. Informed consent was given before the study; the indications established in the Declaration of Helsinki were followed. The participants were incorporated into a physical training plan for 4 weeks. The program was carried out in the facilities of a military center. Results: After physical training there was a significant decrease in adipose mass (p<0.01) and an increase in muscle mass (p<0.01). There were no significant differences in the somatotype components (Pre: 3.29-4.78-2.59 vs. Post: 2.73-4.72-2.73; p = 0.24). Conclusion: It is concluded that physical training in the military, during a short period of four weeks, causes rapid and significant changes in the body composition of the subjects that are not observed with such clarity through the somatotype(AU)

RESUMO

BACKGROUND: Plantar fasciitis is commonly found among the physically active population, including conscripts. Some studies have reported that being overweight and having psychological symptoms contribute to pain from plantar fasciitis. However, there is a lack of information regarding the physical predictors, and more research is needed to determine the relationship between such predictors and pain intensity from plantar fasciitis in conscripts. OBJECTIVE: To determine which physical and psychological variables act as predictors of pain intensity among Thai novice conscripts with plantar fasciitis. METHODS: Two hundred and seventy Thai novice conscripts without musculoskeletal pain completed the Depression, Anxiety and Stress Scale short version and then received baseline assessment of ankle dorsiflexion angle, ankle plantarflexor strength, and quality of lower extremity movement from a physical therapist. After 10 weeks of military training, 71 of these Thai conscripts developed pain from plantar fasciitis. Multiple linear regression analysis with the forward stepwise method was used to explore the predictors of pain intensity due to plantar fasciitis. RESULTS: Using a forward regression analysis, anxiety (B=0.13; 95% CI, 0.06-0.20; p<0.01) and quality of movement score (B=0.87; 95% CI, 0.28-1.47; p=0.01) were significant predictors of pain intensity. The regression model with these predictors explained 25% of the variability in pain intensity from plantar fasciitis. CONCLUSION: Higher scores of anxiety and movement quality on the lateral step-down task were associated with pain intensity from plantar fasciitis after the completion of a 10-week military program. However, lower ankle dorsiflexion angle and ankle plantarflexor strength did not predict pain intensity.

RESUMO

Resumen Este estudio evaluó el perfil cognitivo y los niveles de desesperanza, depresión y riesgo suicida en un grupo de jóvenes vinculados al proceso de formación de una escuela militar colombiana. En total participaron 114 sujetos, militares regulares de primer año (MR-1A), que representan la totalidad de un contingente particular; todos ellos hombres, con edades entre los diecisiete y los veintidós años, provenientes de hogares ubicados en la región Caribe (41%) y el centro del país (12%), sin ningún tipo de diagnóstico médico o mental relevante. Los resultados indican relaciones lineales y directamente promocionales entre todas las variables, con magnitudes significativas en lo referente a las relaciones depresión-desesperanza (rs= 0,295; ρ = 0,01) y depresión-riesgo suicida (rs= 0,478; ρ = 0,01), siendo esta ultima el reporte más elevado.

Abstract This study evaluated the cognitive profile and the levels of Hopelessness, Depression and Suicide Risk in a youth group linked to the process of forming a Colombian military school. A total of 114 subjects participated, regular military freshman, which representing an entire contingent particular; all male, aged between 17 and 22 years, from households in the Caribbean region (41%) and the center of the country (12%), without any relevant medical or mental diagnosis. The results indicate linear and directly promotional relationships between all variables with significant quantities in relation to depression-hopelessness (rs= 0,295; ρ = 0,01) and depression-suicide risk (rs= 0,478; ρ = 0,01) the latter being the highest report.
